Rheology
The study of the deformation and flow of matter, usually liquids or fluids, and of the plastic flow of solids. The concept covers consistency, dilatancy, liquefaction, resistance to flow, shearing, thixotrophy, and VISCOSITY.
Blood Viscosity
The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.
Erythrocyte Deformability
Ability of ERYTHROCYTES to change shape as they pass through narrow spaces, such as the microvasculature.
Hemorheology
The deformation and flow behavior of BLOOD and its elements i.e., PLASMA; ERYTHROCYTES; WHITE BLOOD CELLS; and BLOOD PLATELETS.
Viscosity
The resistance that a gaseous or liquid system offers to flow when it is subjected to shear stress. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
Erythrocyte Aggregation
The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
Elasticity
Resistance and recovery from distortion of shape.
Hematocrit
The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
Shear Strength
The internal resistance of a material to moving some parts of it parallel to a fixed plane, in contrast to stretching (TENSILE STRENGTH) or compression (COMPRESSIVE STRENGTH). Ionic crystals are brittle because, when subjected to shear, ions of the same charge are brought next to each other, which causes repulsion.
Microfluidics
The study of fluid channels and chambers of tiny dimensions of tens to hundreds of micrometers and volumes of nanoliters or picoliters. This is of interest in biological MICROCIRCULATION and used in MICROCHEMISTRY and INVESTIGATIVE TECHNIQUES.
Suspensions
Colloids with liquid continuous phase and solid dispersed phase; the term is used loosely also for solid-in-gas (AEROSOLS) and other colloidal systems; water-insoluble drugs may be given as suspensions.
Gels
Colloids with a solid continuous phase and liquid as the dispersed phase; gels may be unstable when, due to temperature or other cause, the solid phase liquefies; the resulting colloid is called a sol.
Hydrogels
Water swollen, rigid, 3-dimensional network of cross-linked, hydrophilic macromolecules, 20-95% water. They are used in paints, printing inks, foodstuffs, pharmaceuticals, and cosmetics. (Grant & Hackh's Chemical Dictionary, 5th ed)
Elastic Modulus
Numerical expression indicating the measure of stiffness in a material. It is defined by the ratio of stress in a unit area of substance to the resulting deformation (strain). This allows the behavior of a material under load (such as bone) to be calculated.
Stress, Mechanical
A purely physical condition which exists within any material because of strain or deformation by external forces or by non-uniform thermal expansion; expressed quantitatively in units of force per unit area.
Mechanical Processes
The behaviors of materials under force.
Erythrocyte Count
The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.
Factor XIIIa
Activated form of FACTOR XIII, a transglutaminase, which stabilizes the formation of the fibrin polymer (clot) culminating the blood coagulation cascade.
Blood Physiological Phenomena
Physiological processes and properties of the BLOOD.
Erythrocytes
Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.
Anemia, Sickle Cell
A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.
Microscopy, Atomic Force
A type of scanning probe microscopy in which a probe systematically rides across the surface of a sample being scanned in a raster pattern. The vertical position is recorded as a spring attached to the probe rises and falls in response to peaks and valleys on the surface. These deflections produce a topographic map of the sample.
Blood Flow Velocity
A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.
Phase Transition
A change of a substance from one form or state to another.
Biomechanical Phenomena
The properties, processes, and behavior of biological systems under the action of mechanical forces.
Emulsions
Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.
Biophysics
The study of PHYSICAL PHENOMENA and PHYSICAL PROCESSES as applied to living things.
Surface Properties
Characteristics or attributes of the outer boundaries of objects, including molecules.

The forward rate of binding of surface-tethered reactants: effect of relative motion between two surfaces. (1/1782)

The reaction of molecules confined to two dimensions is of interest in cell adhesion, specifically for the reaction between cell surface receptors and substrate-bound ligand. We have developed a model to describe the overall rate of reaction of species that are bound to surfaces under relative motion, such that the Peclet number is order one or greater. The encounter rate between reactive species is calculated from solution of the two-dimensional convection-diffusion equation. The probability that each encounter will lead to binding depends on the intrinsic rate of reaction and the encounter duration. The encounter duration is obtained from the theory of first passage times. We find that the binding rate increases with relative velocity between the two surfaces, then reaches a plateau. This plateau indicates that the increase in the encounter rate is counterbalanced by the decrease in the encounter duration as the relative velocity increases. The binding rate is fully described by two dimensionless parameters, the Peclet number and the Damkohler number. We use this model to explain data from the cell adhesion literature by incorporating these rate laws into "adhesive dynamics" simulations to model the binding of a cell to a surface under flow. Leukocytes are known to display a "shear threshold effect" when binding selectin-coated surfaces under shear flow, defined as an increase in bind rate with shear; this effect, as calculated here, is due to an increase in collisions between receptor and ligand with increasing shear. The model can be used to explain other published data on the effect of wall shear rate on the binding of cells to surfaces, specifically the mild decrease in binding within a fixed area with increasing shear rate.  (+info)

Five caffeine metabolite ratios to measure tobacco-induced CYP1A2 activity and their relationships with urinary mutagenicity and urine flow. (2/1782)

To choose a sensitive protocol to discriminate populations exposed and not exposed to inducers, five urinary metabolite ratios (MRs) [MR1 (17X + 17U)/137X, MR2 (5-acetylamino-6-formylamino-3-methyluracil [AFMU] + 1X + 1U)/17U, MR3 (17X/137X), MR4 (AFMU + 1X + 1U + 17X + 17U)/137X, and MR5 (AFMU + 1X + 1U)/17X] were calculated in 4-5 h and 0-24 h urine samples after caffeine intake. One hundred twenty-five healthy volunteers (59 nonsmokers and 66 smokers) were included in the study. All ratios showed a log-normal distribution. MR2 in the two time intervals was the only ratio nondependent on the urine flow. Differences between nonsmokers and smokers could be detected with all ratios at 4-5 h. However, only MR2 and, to a lesser extent, MR5 allowed the discrimination of higher cytochrome P450 1A2 (CYP1A2) activity in smokers in the 0-24 h sample. Although smokers had increased urinary mutagenicity in relation to nonsmokers, a significant association between MRs and urine mutagenicity was observed only with MR2 in the 4-5 h interval; this ratio/time schedule being that of higher association with tobacco consumption. The most flow-dependent ratios, MR1, MR3, and MR4, were closely correlated with each other at the two intervals. The flow dependency profile of each ratio may explain their different power to indicate both tobacco exposure and tobacco-derived mutagenicity. In conclusion, MR2 in the period of 4-5 h after caffeine intake seems preferable, especially at high urine flow rates.  (+info)

Single-polymer dynamics in steady shear flow. (3/1782)

The conformational dynamics of individual, flexible polymers in steady shear flow were directly observed by the use of video fluorescence microscopy. The probability distribution for the molecular extension was determined as a function of shear rate, gamma;, for two different polymer relaxation times, tau. In contrast to the behavior in pure elongational flow, the average polymer extension in shear flow does not display a sharp coil-stretch transition. Large, aperiodic temporal fluctuations were observed, consistent with end-over-end tumbling of the molecule. The rate of these fluctuations (relative to the relaxation rate) increased as the Weissenberg number, gamma;tau, was increased.  (+info)

Chordal force distribution determines systolic mitral leaflet configuration and severity of functional mitral regurgitation. (4/1782)

OBJECTIVES: The purpose of this study was to investigate the impact of the chordae tendineae force distribution on systolic mitral leaflet geometry and mitral valve competence in vitro. BACKGROUND: Functional mitral regurgitation is caused by changes in several elements of the valve apparatus. Interaction among these have to comply with the chordal force distribution defined by the chordal coapting forces (F(c)) created by the transmitral pressure difference, which close the leaflets and the chordal tethering forces (FT) pulling the leaflets apart. METHODS: Porcine mitral valves (n = 5) were mounted in a left ventricular model where leading edge chordal forces measured by dedicated miniature force transducers were controlled by changing left ventricular pressure and papillary muscle position. Chordae geometry and occlusional leaflet area (OLA) needed to cover the leaflet orifice for a given leaflet configuration were determined by two-dimensional echo and reconstructed three-dimensionally. Occlusional leaflet area was used as expression for incomplete leaflet coaptation. Regurgitant fraction (RF) was measured with an electromagnetic flowmeter. RESULTS: Mixed procedure statistics revealed a linear correlation between the sum of the chordal net forces, sigma[Fc - FT]S, and OLA with regression coefficient (minimum - maximum) beta = -115 to -65 [mm2/N]; p < 0.001 and RF (beta = -0.06 to -0.01 [%/N]; p < 0.001). Increasing FT by papillary muscle malalignment restricted leaflet mobility, resulting in a tented leaflet configuration due to an apical and posterior shift of the coaptation line. Anterior leaflet coapting forces increased due to mitral leaflet remodeling, which generated a nonuniform regurgitant orifice area. CONCLUSIONS: Altered chordal force distribution caused functional mitral regurgitation based on tented leaflet configuration as observed clinically.  (+info)

von Willebrand factor contained in a high purity FVIII concentrate (Fanhdi) binds to platelet glycoproteins and supports platelet adhesion to subendothelium under flow conditions. (5/1782)

BACKGROUND AND OBJECTIVE: There is evidence suggesting that von Willebrand factor (VWF) from high purity factor VIII concentrates could be of clinical use in the management of patients suffering from VWD. We analyzed structural and functional characteristics of VWF present in a high purity factor VIII concentrate VWFHPC (Fanhdi). The multimeric structure, the ability to bind to platelet GP Ib/IX or GP IIb/IIIa, and the capacity of VWFHPC to promote platelet adhesion on injured vessels were investigated and compared with that present in standard plasma cryoprecipitates [VWFCRYO]. DESIGN AND METHODS: Binding studies were carried out by incubating radiolabeled VWF and washed platelets, which were activated with either ristocetin (1 mg/mL; for GP Ib/IX), or thrombin (2.5 U/mL; for GP IIb/IIIa). Platelet adhesion was assessed in a perfusion system (shear rate = 800 s-1, 10 min) in which the source of VWF was added (at 0.4 or 0.8 U/mL VWF:Ag) to washed platelets and red cells suspended in a human albumin solution. The deposition of platelets onto the perfused subendothelial surface was morphometrically evaluated and expressed as percentage of surface coverage (%SC). RESULTS: The VWFHPC (152 Units VWF:RCof/mg protein; VWF:RCof/VWF:Ag = 0.97), lacked only a small proportion of high-molecular-weight multimers present in VWFCRYO. Binding affinities (Kd values, nM) of VWFHPC were similar to those of VWFCRYO (5.3 +/- 0.86 vs 5.2 +/- 0.95, for GP Ib/IX; and 11.6 +/- 2.7 vs 15.4 +/- 1.7 for GPIIb-IIIa). A slightly, though not significantly, higher binding capacity for these receptors (Bmax values, molecules/pit) was obtained for VWFHPC. The %SC in perfusions in the presence of albumin was < 10%. Addition of VWFHPC or VWFCRYO significantly increased the %SC, with values of 27.1 +/- 4.9 and 17.5 +/- 2.8%, respectively with 0.4 U/mL (p < 0.004 and p < 0.02 vs albumin); and 30.8 +/- 4.9% and 20.03 +/- 4.1%, respectively, at 0.8 U/mL (p < 0.001 and p < 0.02 vs albumin). INTERPRETATION AND CONCLUSIONS: Our data show that VWF present in the high purity FVIII concentrate Fanhdi retains the functional capacity to bind to GPs Ib/IX and IIb/IIIa and to promote platelet adhesion onto exposed subendothelium.  (+info)

Expression of functional selectin ligands on Th cells is differentially regulated by IL-12 and IL-4. (6/1782)

Immune responses may be qualitatively distinct depending on whether Th1 or Th2 cells predominate at the site of Ag exposure. T cell subset-specific expression of ligands for vascular selectins may underlie the distinct patterns of recruitment of Th1 or Th2 cells to peripheral inflammatory sites. Here we examine the regulation of selectin ligand expression during murine T helper cell differentiation. Large numbers of Th1 cells interacted with E- and P-selectin under defined flow conditions, while few Th2 and no naive T cells interacted. Th1 cells also expressed more fucosyltransferase VII mRNA than naive or Th2 cells. IL-12 induced expression of P-selectin ligands on Ag-activated naive T cells, even in the presence of IL-4, and on established Th2 cells restimulated in the presence of IL-12 and IFN-gamma. In contrast, Ag stimulation alone induced only E-selectin ligand. Interestingly, restimulation of established Th2 cells in the presence of IL-12 and IFN-gamma induced expression of P-selectin ligands but not E-selectin ligands; IFN-gamma alone did not enhance expression of either selectin ligand. In summary, functional P- and E-selectin ligands are expressed on most Th1 cells, few Th2 cells, but not naive T cells. Furthermore, selectin ligand expression is regulated by the cytokine milieu during T cell differentiation. IL-12 induces P-selectin ligand, while IL-4 plays a dominant role in down-regulating E-selectin ligand.  (+info)

Volume flow estimation by colour duplex. (7/1782)

OBJECTIVE: To assess the accuracy of volume blood flow using a digitised colour duplex scanner. DESIGN: Observer-blinded experimental study. MATERIALS AND METHODS: Method comparison was performed with linear regression analysis of 89 paired observations in 11 anaesthetised pigs. A Siemens Sonoline Elegra ultrasound system was used for transcutaneous volume flow estimation using invasive transit time flowmetry by Cardiomed as a reference. RESULTS: For the individual measurement we found a standard error of the estimate (SEE) of 22 ml/min. For the regression line, however, the SEE was only 0.2 ml/min. CONCLUSIONS: Digitised colour-duplex sonography has a volume flow measurement error that is too high for single measurements in the individual patient for the method to be useful in clinical decision making, but sufficient for examinations of groups and comparison of groups.  (+info)

Thiol oxidation of actin produces dimers that enhance the elasticity of the F-actin network. (8/1782)

Slow oxidation of sulfhydryls, forming covalently linked actin dimers and higher oligomers, accounts for increases in the shear elasticity of purified actin observed after aging. Disulfide-bonded actin dimers are incorporated into F-actin during polymerization and generate cross-links between actin filaments. The large gel strength of oxidized actin (>100 Pa for 1 mg/ml) in the absence of cross-linking proteins falls to within the theoretically predicted order of magnitude for uncross-linked actin filament networks (1 Pa) with the addition of sufficient concentrations of reducing agents such as 5 mM dithiothreitol or 10 mM beta-mercaptoethanol. As little as 1 gelsolin/1000 actin subunits also lowers the high storage modulus of oxidized actin. The effects of gelsolin may be both to increase filament number as it severs F-actin and to cover the barbed end of an actin filament, which otherwise might cross-link to the side of another filament via an actin dimer. These new findings may explain why previous studies of actin rheology report a wide range of values when purified actin is polymerized without added regulatory proteins.  (+info)

Rheological characterization of polysaccharide gelsRheological characterization of polysaccharide gels
The rheological measurements included both rotational and oscillatory measurements in different conditions, where several chemical and physical properties were measured with Anton Paar MCR302 dynamic rotational rheometer. Studied polysaccharide gels can be clearly defined to be shear thinning and thixotropic materials. They have strong gel forming properties even at low concentrations, which explains the superior thickening behavior for some of the samples. Along with rheological characterization of selected materials the factors behind different phenomena were investigated. To reveal value and potential use of polysaccharide gels the influence of various factors such as concentration, temperature and ionic strength were determined. The measurements showed a clear difference between studied materials under investigated external parameters ...

Rheology in Thixo- and Rheocasting Processes: A Rheological Characterization of Aluminum Alloys :: Anton-Paar.comRheology in Thixo- and Rheocasting Processes: A Rheological Characterization of Aluminum Alloys :: Anton-Paar.com
Different shear rates/shear stresses showed a significant influence on the rheological behavior and thus the viscosity of the alloy. This was true for the liquid material as well as the liquid-solid phase between liquidus and solidus temperatures, which is crucial for the casting processes. The viscosity at high applied shear stresses (like those used in thixo- and rheocasting processes) is significantly lower than when measured at rest. Structural changes on metallographic microsection were observed linking the loss of dendritic structure with the rheological data. Thus high temperature rheology is shown to be a powerful tool to investigate metal alloys in modern casting processes. Introduction Unlike in normal casting processes, thixo- and rheocasting processes employ liquid-solid mixtures (called semisolids within metallurgy) containing non-dendritic solid fractions that are pressed into dies. One of the main advantages of liquid-solid material (semi-solids) castings as opposed to ...

British Library EThOS: The rheology of crude oil and carbon dioxide mixturesBritish Library EThOS: The rheology of crude oil and carbon dioxide mixtures
The rheology of crude oil mixtures at equilibrium with carbon dioxide (CO2) was studied at elevated pressures and temperatures, similar to those found for oil reservoir conditions. The focus of the work presented in this thesis concerns the measurement of the rheological properties of CO2 saturated mixtures of crude oil. The rheology measurements were made using a high-pressure rheometer coupled to a fluid flow system designed and built in this project. The flow system comprised a mixing vessel and fluid flow loop that allowed the test fluid to be brought into equilibrium with CO2 by stirring and circulating through the rheometer measurement geometry under the pressure and temperature required. Measurements were made for three different fluids saturated with CO2: a light crude oil from the Gulf of Mexico (GoM), Zuata heavy crude oil, and an emulsion of Zuata crude oil with deionized water. The rheological measurements for the GoM crude oil were performed at temperatures of 23 °C and 50 °C and ...

Particle image velocimetry for microscale blood flow measurement | TU Delft RepositoriesParticle image velocimetry for microscale blood flow measurement | TU Delft Repositories
Faculty Mechanical Maritime and Materials Engineering. Date 2008-04-21. Abstract The development, the regulation, and the pathology of the circulatory system (e.g. cardiogenesis, thermoregulation, atherosclerosis) are determined by blood flow induced mechanical forces. While this proposition has been confirmed during recent years, the exact mechanisms still remain unclear. This is mainly due to the fact that those forces could hardly be measured. The goal of the research described in this thesis is the development of a measurement technique that can provide such data for living organisms. Fluid mechanical forces can be deduced from spatial velocity information, as provided by particle image velocimetry. Small, artificial, fluorescent particles with a hydrophilic coating are used to determine the fluid velocity. Fluorescence enables the interference-free recording of the particle motion, and the coating makes the particles invisible to the biological system. Three dimensional flow is accessed ...

A parallelogram channel has drawn very little or no attention in the open literature although it appears as a cross-sectional configuration of some gas turbine rotor blades. Particle image velocimetry (PIV) is presented of local flow structure in a two-pass 90 deg ribbed-wall parallelogram channel with a 180 deg sharp turn. The channel has a cross-sectional equal length, 45.5 mm, of adjacent sides and two pairs of opposite angles are 45 deg and 135 deg. The rib height to channel height ratio is 0.1. All the measurements were performed at a fixed Reynolds number, characterized by channel hydraulic diameter of 32.17 mm and cross-sectional bulk mean velocity, of 10,000 and a null rotating number. Results are discussed in terms of the distributions of streamwise and secondary-flow mean velocity vector, turbulent intensity, Reynolds stress, and turbulent kinetic energy of the cooling air. It is found that the flow is not periodically fully developed in pitchwise direction through the inline 90 deg ...

Rheological Characterization of Polymer Modified BitumensRheological Characterization of Polymer Modified Bitumens
Various polymer modified bitumens (PmBs) were prepared and characterized using a dynamic shear rheometer and a bending beam rheometer. PmBs differ considerably in viscoelastic properties depending on base bitumen, and polymer type and content. The rheology of PmBs is strongly related to the morphology, and is also affected by sample preparation.

were the still and moving wave gauge data. First, the wave gauge remained stationary over the horizontal bottom of the flume and recorded water surface elevations with time. Data were collected for two minutes at a frequency of 60 Hz to analyze wave height and period. Secondly, the carriage which supported the wave gauge was slowly moved down the length of the deep water section of the tank. Moving the wave gauge slowly as the waves propagated past allowed for detection of reflected waves in the tank as described by Dean and Dalrymple (1991). The wave gauge was first slowly moved opposite the direction of wave propagation, and then back in the direction of wave propagation. Again, the data was collected for a length of two minutes at a frequency of 60 Hz. The third set of data collected by the wave gauge was not common to all runs. By slowly moving the wave gauge through the surf zone portion of the tank, the wave set-up could be determined. It was hoped to corroborate the wave set-up measured ...

Simultaneous Rheology and Raman Spectroscopy Part 3: Tracking Polymer Crystallization - Producing Polymers/PlasticsSimultaneous Rheology and Raman Spectroscopy Part 3: Tracking Polymer Crystallization - Producing Polymers/Plastics
Rheology is the analytical method of choice to correlate the absolute flow and deformation characteristics of a given product with its behavior towards a certain processing or application step. However, rheology as an integral method only yields answers on the bulk of the investigated sample. It does not give any insights into what is actually happening on the molecular level during a certain processing step.. Raman spectroscopy has shown its ability as a powerful, effective and non-invasive method for chemical analysis. Coupling a rheometer with a Raman spectrometer provides direct information about the molecular structure and the mechanical properties. This is extremely useful for studying the crystallization behavior of polymer melts during processing.

Nonlinear Continuum Mechanics, Rheology and the Dynamo | Institute for Mathematics and its ApplicationsNonlinear Continuum Mechanics, Rheology and the Dynamo | Institute for Mathematics and its Applications
During the past decade, geoscientists have come to appreciate the often-dominant role played by complex and nonlinear rheologies in the deformation of geologic materials. This is nowhere more evident than in the earths crust and mantle where effective viscosities can vary over many orders of magnitude and different modes of deformation occur. On the largest scale, plate tectonics occurs because of the poorly understood multi-rheological behavior of crustal and mantle rocks. On a smaller scale, complex geomorphic features, such as those in evidence in the Sierra Nevada, are the outcome of flows which are dramatically influenced by variable viscosity, phase transitions, and other physical and chemical properties. Nonlinear rheology, through a number of microscopic processes and macroscopic interactions such as thermal feedback, results in a rich variety of flow behavior including strain localization and instability leading to faulting. Such behaviors are ultimately responsible for such diverse ...

In-line rheology of cement grouts - Feasibility study of an ultrasound based non-invasive methodIn-line rheology of cement grouts - Feasibility study of an ultrasound based non-invasive method
Grouting is used in underground construction to reduce the water flow into tunnels and caverns and to limit the lowering of the surrounding groundwater table. Due to their wide availability and low cost relative to other materials, cement based materials are commonly used as grouts and, in this context, the rheology of the cement grout is an important factor. Rheological properties of cement grout such as viscosity and yield stress are commonly measured off-line using laboratory instruments, and some simple tools are available to make field measurements. However, these methods often lack accuracy and reliability. Although the rheological properties of the grout used play a fundamental role in design and execution, no method has yet been developed to measure these properties in-line in field work.. In this work, for the first time, an in-line rheometry method combining the Ultrasound Velocity Profiling (UVP) technique with Pressure Difference (PD) measurements, known as UVP+PD, was successfully ...

Asymmetric soft-hard colloidal mixtures: osmotic effects, glassy states and rheologyAsymmetric soft-hard colloidal mixtures: osmotic effects, glassy states and rheology
Whereas mixtures of colloids and non-adsorbing polymers have been studied in great detail in the last two decades, binary colloidal mixtures have not received much attention. Yet, fragmental evidence from asymmetric mixtures of hard spheres indicates a wide-ranging, complex behavior from liquid to crystal to single glass and to double glass, and respective rich rheology. Recently, we addressed the question of softness by investigating a mixture of soft and virtually hard colloidal spheres. We found an unprecedented wealth of states including repulsive single glass (RG), liquid, arrested phase separation (APS) and double glass (DG). This is a consequence of the coupling of softness and osmotic forces due to the hard component. We now report on the rheology of the different states with emphasis on the nonlinear response during start-up of stress at constant rate, its relaxation upon flow cessation, and large amplitude oscillatory shearing. Distinct features are identified, whereas comparison with ...

In consideration of the insolubility in water, sensitivity to heat and wide application in the oil and gas industry as a degradable additive, this paper introduces polylactic acid (PLA) to a self-degradable temporary sealing material (SDTSM) to investigate its effect on the SDTSM performance and evaluate its potential to improve the rheological properties and further promote the self-degradation of the material. The thermal degradation of PLA, the rheological properties, compressive strength, hydrated products and water absorption of SDTSMs with different PLA dosages were tested. The analysis showed that the addition of 2% PLA increased the fluidity by 13.18% and reduced the plastic viscosity by 38.04%, when compared to those of the SDTSM without PLA. PLA increased the water absorption of 200 °C-heated SDTSM and had small effect on the types but decreased the hydrate products of 85 °C-cured SDTSM, and created plenty of pores in 200 °C-heated SDTSM. PLA enhanced the self-degradation level of SDTSM by

The rheological properties of three different microstructures of hydrophobically modified alkalisoluble polymers (telechelic, multisticker and combined) in the presence of various concentrations of anionic surfactant and salt (NaCl) were investigated. Associative polymers containing both ionic sites and small number of hydrophobic groups were obtained, and their thickening properties in aqueous solutions, were investigated. Solution polymerization was used for obtaining the different polymers. Relationships between hydrophobe, sodium dodecyl sulfate (SDS) and NaCl concentration are proposed. Owing to the competition between attractive hydrophobic interaction and repulsive electrostatic interactions, such hydrophobically modified polymers exhibit various rheological behaviors in aqueous solutions, depending on microstructure of polyelectrolyte, SDS and NaCl concentrations.

Microrheology is the study of the flow and deformation of fluids on the micrometre scale. It has many benefits over the use of traditional rheomoeters to measure the mechanical properties of fluids. Microrheology has small sample sizes, can extract information about the underlying heterogeneities, often has a lower setup cost, can measure to higher frequencies and can measure the viscoelasticity of in-vivo samples. Work has been carried out to setup and calibrate four different microrheology techniques, namely: diffusing wave spectroscopy, dynamic light scattering, multiple particle tracking and probe laser tracking with a quadrant photodiode and optical traps. This resulted in the ability to measure the viscoelastic properties of a material over approximately eight orders of magnitude, with nanometre resolution on the most sensitive technique; diffusing wave spectroscopy. The link between free Brownian motion and a particle diffusing in a harmonic potential was used to calibrate the trap ...

Development of a Blood Flow Measurement Protocol Using Particle Image by Jennifer Chi-Ying GoDevelopment of a Blood Flow Measurement Protocol Using Particle Image by Jennifer Chi-Ying Go
Peripheral Arterial Occlusive Disease (PAOD) is an acquired inflammatory disease where a peripheral artery becomes occluded due to the buildup of atherosclerotic plaques. In patients that possess collateral arteries, an occlusion can lead to shear induced outward remodeling, arteriogenesis, of these collaterals, partially restoring blood flow. However, newly remodeled collaterals exhibit reduced functional vasodilation, which may impair normal activity, such as ambulation. To model chronic ischemia and arteriogenesis in collaterals, a femoral artery ligation in a murine hindlimb is commonly performed. Previous efforts by our group involved measurements of collateral artery diameter to assess the impact of arteriogenesis on functional vasodilation/vascular reactivity; however diameter measurements are not as descriptive as an assessment of flow, and performing particle image velocimetry allows the change in blood flow control to be investigated. Particle image velocimetry was performed in the profunda

Authors: Baskurt, Oguz K. Article Type: Review Article Abstract: It is has been known for more than 80 years that compared to in vitro determinations, blood behaves as a less viscous fluid under in vivo flow conditions. The experiments of Whittaker and Winton were among the first dealing with the in vivo effects of altered blood rheology, and experimental studies during the second half of 20th century have provided additional evidence for the complexity of in vivo hemodynamics-hemorheology relationships. Careful studies indicate that the impact of a given blood rheology alteration is determined by the properties of the experimental model (e.g., organ or tissue under investigation), experimental approach (e.g., …intravital microscopy, whole organ perfusion) and method used to modify blood rheology. In addition, vascular control mechanisms may play a major role in the resulting hemodynamic effects of a hemorheological alteration: (1) a response simply related to metabolic autoregulation in which ...

In this work, three linear isotactic polypropylenes with different weight-average molecular weights, M-w, and comparable polydispersities were used to produce nonwovens by melt blowing technology at two different temperatures, T. The air/polymer flow rate was changed to maintain the same average fiber diameter, resulting in a different broadness of fiber diameter distribution, which was quantified by the coefficient of variation, CV. The elasticity of the material was evaluated by the reptation-mode relaxation time, lambda(1), and the Rouse-mode reorientation time, lambda(2), determined from the deformation rate dependent shear viscosity data. Extensional rheology was evaluated using uniaxial extensional viscosity measured over a very wide range of strain rates (2 x 10(4) s(-1)-2 x 10(6) s(-1)) using entrance pressure drop and Gibson methods. An obtained plateau value of uniaxial extensional viscosity at the highest extensional strain rates, eta(E,infinity) (normalized by the three times ...

Interactions between internal forces, body stiffness, and fluid environment in a neuromechanical model of lamprey swimming.
Animal movements result from a complex balance of many different forces. Muscles produce force to move the body; the body has inertial, elastic, and damping properties that may aid or oppose the muscle force; and the environment produces reaction forces back on the body. The actual motion is an emergent property of these interactions. To examine the roles of body stiffness, muscle activation, and fluid environment for swimming animals, a computational model of a lamprey was developed. The model uses an immersed boundary framework that fully couples the Navier-Stokes equations of fluid dynamics with an actuated, elastic body model. This is the first model at a Reynolds number appropriate for a swimming fish that captures the complete fluid-structure interaction, in which the body deforms according to both internal muscular forces and external fluid forces. Results indicate that identical muscle activation patterns can produce different kinematics depending on body stiffness, and the optimal value ...

CiNii 博士論文 - Characteristics of shear-driven micro flow between stationary and rotating disks
博士論文. Recently, quantitative flow visualization has become an important tool to investigate three-dimensional complex flow structures in microfluidic. The development of laser, computer and digital image processing techniques made it possible to extract velocity field information from visualized flow images of tracer particles. Particle image velocimetry (PIV) / particle tracking velocimetry (PTV) method has become one of the most useful flow diagnostic technologies in the modern history of fluid mechanics. The particle based velocimetry techniques measure the whole velocity field information in a plane by dividing that is placements Δx and Δy of tracer particles with the time interval Δt during which the particles were displaced. Since the flow velocity is inferred from the particle displacement, it is also important to select proper tracer particles that follow the flow motion accurately without changing the flow properties. These methods have been accepted as a reliable and ...

Difference between revisions of Rheological behavior - Soft-Matter
Magnetorheological Fluid The other fluid that can reinforce Kevlar armor is magnetorheological (MR) fluid. MR fluids are oils that are filled with iron particles. Often, surfactants surround the particles to protect them and help keep them suspended within the fluid. Typically, the iron particles comprise between 20 and 40 percent of the fluids volume. The particles are tiny, measuring between 3 and 10 microns. However, they have a powerful effect on the fluids consistency. When exposed to a magnetic field, the particles line up, thickening the fluid dramatically. The term magnetorheological comes from this effect. Rheology is a branch of mechanics that focuses on the relationship between force and the way a material changes shape. The force of magnetism can change both the shape and the viscosity of MR fluids. The hardening process takes around twenty thousandths of a second. The effect can vary dramatically depending on the composition of the fluid and the size, shape and strength of the ...

Bubbles are ubiquitous in magma during eruption and influence the rheology of the suspension. Despite this, bubble-suspension rheology is routinely ignored in conduit-flow and eruption models, potentially impairing accuracy and resulting in the loss of important phenomenological richness. The omission is due, in part, to a historical confusion in the literature concerning the effect of bubbles on the rheology of a liquid. This confusion has now been largely resolved and recently published studies have identified two viscous regimes: in regime 1, the viscosity of the two-phase (magma-gas) suspension increases as gas volume fraction phi increases; in regime 2, the viscosity of the suspension decreases as phi increases. The viscous regime for a deforming bubble suspension can be determined by calculating two dimensionless numbers, the capillary number Ca and the dynamic capillary number Cd. We provide a didactic explanation of how to include the effect of bubble-suspension rheology in continuum, ...

Rheological characterization of okra pectins - University of Huddersfield RepositoryRheological characterization of okra pectins - University of Huddersfield Repository
Polysaccharides from okra pods (Abelmoschus esculentus) were extracted using a sequential extraction protocol and compared with a simple extraction at pH 6. Rheological properties of three okra extracts were then investigated by means of molecular weight determination, dilute solution rheology, steady shear and oscillatory rheological measurements. The extraction protocols resulted in extracts of relatively high purity and multimodal molecular weight distribution. Furthermore, molecular parameters of the isolated biopolymers such as intrinsic viscosity, Huggins constant, critical concentration and coil overlap parameter were calculated from dilute solution viscometry. Investigation of the generalized flow behaviour using a modified Cross equation and Cox-Merz plots showed evidence that as concentration increases specific interactions start taking place among the polymeric chains that modify the rheological behaviour of the extracts. The change in the rheological behaviour could not only be ...

With the ever increasing market demand for rubber products, those in compounding and manufacturing are tasked with the challenge of increasing output without sacrificing efficiencies. This naturally increases the requirements of processes such as mixing, extruding, and injection molding in the rubber industry. Many factors contribute to the success or failure of a compound formulation to meet the required processing and performance criteria. The physical and chemical properties of the raw polymer are among the most important, including molecular weight, molecular weight distribution, and the degree of long-chain branching. Rheological characterization is perhaps the most powerful technique for quickly and easily obtaining information about these properties, enabling process/production engineers and compounders invaluable information about processability of raw polymers and processed compounds.

One of the room temperature ionic liquids (RTILs), 1-butyl-3-methylimidazoliumchloride ([BMIM]Cl) was chosen to prepare the concentrated solutions of Polyacrylonitrile(PAN). The rheological behaviors of the solutions were measured with rotational rheometryunder different conditions, including temperatures, concentration, and molecular weight ofPAN. The solutions exhibited shear-thinning behaviors, similar to that of PAN/DMFsolutions. The viscosities decreased with the increasing of shear rates. However, theviscosity decreased sharply at high shear rates when the concentration was up to 16wt%. Thedependence of the viscosity on temperature was analyzed through the determination of theapparent activation energy. Unusually, the viscosity of solutions of higher concentration islower than that of lower concentration. Similarly, the viscosity of low molecular weightPAN was higher than high molecular weight PAN at high shear rates. The dynamicrheological measurement indicates the loss modulus is much higher

Changes in rheological properties and amylase activities of trifoliate yam, Dioscorea dumetorum, starch after harvestChanges in rheological properties and amylase activities of trifoliate yam, Dioscorea dumetorum, starch after harvest
Changes in rheological properties and amylase activities occurring in trifoliate yam, Dioscorea dumetorum, starch after harvest were investigated. Trifoliate yam tubers were harvested and stored under tropical ambient (28°C) and cold room conditions (4°C) for 12, 24 and 36 h. The D. dumetorum starches were extracted from the tubers under study and samples were evaluated for changes in their rheological properties (paste characteristics) during storage and to study the action of amylases on D. dumetorum starch after harvesting. The post-harvest activities of α and β-amylases were also studied to evaluate their rate of action on D. dumetorum starch.

Two-dimensional in-cylinder velocity distributions measured with Particle Image Velocimetry were compared with computed results from Computational Fluid Dynamics codes. A high-swirl, two-valve, four-stroke transparent-combustion-chamber research engine was used. Comparisons were made of mean-flow velocity distributions, swirl-ratio evolution during the intake and compression strokes, and turbulence distributions at top-dead-center compression. This comparison with the measured flows led to more accurate calculations by identifying code improvements including swirl in the residual gas, modeling of the gas exchange during the valve overlap, and improved numerical accuracy ...

Rheology - WikipediaRheology - Wikipedia
Rheology (/riːˈɒlədʒi/; from Greek ῥέω rhéō, flow and -λoγία, -logia, study of) is the study of the flow of matter, primarily in a liquid state, but also as soft solids or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is the science of deformation and flow within a material. It is a branch of physics which deals with the deformation and flow of materials, both solids and liquids.[1] The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a suggestion by a colleague, Markus Reiner.[2][3] The term was inspired by the aphorism of Simplicius (often attributed to Heraclitus), panta rhei, everything flows,[4][5] and was first used to describe the flow of liquids and the deformation of solids. It applies to substances that have a complex microstructure, such as muds, sludges, suspensions, polymers and other glass formers (e.g., silicates), as ...

Admixtures were unable to reduce the yield stress of waterglass-activated slag pastes, but the inclusion of a naphthalene derivative admixture in NaOH-activated slag pastes reduced the yield stress by 80%.

Effect of Six non-Newtonian Viscosity Models on Hemodynamic Parameters of Pulsatile Blood Flow in Stenosed Artery
A numerical study of hemodynamic parameters of pulsatile blood flow is presented in a stenotic artery with non-Newtonian models using ADINA. Blood flow was considered laminar, and arterial wall was considered rigid. Studied stenosis severities were 30%, 50% and 70% of the cross-sectional area of the artery. Six non-Newtonian models were used to model the non-Newtonian behavior of blood, and their results were compared with the Newtonian model. The results showed that in Power Law and Walburn-Schneck models, unlike other models, shear stress values before and after the stenosis were smaller than Newtonian models. Also, in maximum flow rate, the Carreua, generalized Power Law, Casson, and Carreua-Yasuda models showed a reduction in global importance factor of non-Newtonian behavior, and as a result, the results approached Newtonian model. In minimum flow rate, the global importance factor of Newtonian behavior increased, which highlighted the importance of Newtonian model. In minimum flow rate, Carreua

Changed blood rheology in patients with idiopathic dilated cardiomyopathyChanged blood rheology in patients with idiopathic dilated cardiomyopathy
Abstract. Rheologic properties of blood were studied in 8 patients with dilated cardiomyopathy (DCM) and in 10 healthy subjects. Whole-blood viscosity was measured at four different shear rates, by means of a computer-controlled rotational viscometer. The patients had significantly higher blood viscosity at all shear rates, both at their natural hematocrits and after an in vitro adjustment of sample hematocrits to 45%. Erythrocyte filterability (5 μm pore size) was significantly lower, fibrinogen concentration significantly higher, and HDLcholesterol concentration significantly lower in the patient group. No significant differences were found regarding hematocrit, mean corpuscular volume, haemoglobin concentration, leukocyte count and filterability (8 μm pore size), plasma viscosity, and total cholesterol concentration.. The measured hemorheologic abnormalities may contribute to the previously reported reduction of coronary blood flow reserve in DCM patients and to myocardial microcirculatory ...

Within the present investigation, a miniature viscous disk pump (VDP) is utilized to characterize and quantify non-Newtonian fluid elastic turbulence effects, relative to Newtonian flow behavior. Such deviations from Newtonian behavior are induced by adding polyacrylamide to purified water. The VDP consists of a 10.16 mm diameter disk that rotates above a C-shaped channel with inner and outer radii of 1.19 mm and 2.38 mm, respectively. A channel depth of 230 μm is employed. Fluid inlet and outlet ports are located at the ends of the C-shaped channel. Experimental data are given for rotational speeds of 126 1/s, 188 1/s, 262 1/s, and 366 1/s, pressure rises as high as 700 Pa, and flow rates up to approximately 0.00000005 m3/s. Reynolds number ranges from 2.9 to 6.5 for the non-Newtonian polyacrylamide solution flows and from 51.6 to 149.8 for the Newtonian pure water flows. To characterize deviations due to non-Newtonian elastic turbulence phenomena, two new parameters are introduced, PrR and ...

淡江大學 | 教師歷程系統 | The effect of turbulent viscous shear stress on red blood cell hemolysis淡江大學 | 教師歷程系統 | The effect of turbulent viscous shear stress on red blood cell hemolysis
Non-physiologic turbulent flow occurs in medical cardiovascular devices resulting in hemodynamic stresses that may damage red blood cells (RBC) and cause hemolysis. Hemolysis was previously thought to result from Reynolds shear stress (RSS) in turbulent flows. A more recent hypothesis suggests that turbulent viscous shear stresses (TVSS) at spatial scales similar in size to RBCs are related to their damage. We applied two-dimensional digital particle image velocimetry to measure the flow field of a free-submerged axisymmetric jet that was utilized to hemolyze porcine RBCs in selected locations. Assuming a dynamic equilibrium for the sub-grid scale (SGS) energy flux between the resolved and the sub-grid scales, the SGS energy flux was calculated from the strain rate tensor computed from the resolved velocity fields. The SGS stress was determined by the Smagorinsky model, from which the turbulence dissipation rate and then TVSS were estimated. Our results showed the hemolytic threshold of the ...

Interactions between organisms and complex flow fields are of significant consequence to many ecological processes (e.g. predator-prey interactions, swimming behavior, spatial dispersion and distribution, diel migration). Thus, turbulence-organism interactions have received much recent attention (e.g. Prairie et al., 2012; Guasto et al., 2012; Durham et al., 2013; Jumars et al., 2009; Yamazaki and Squires, 1996). Quantifying turbulent flow fields with high spatial and temporal resolution, and relating them to the behavior and distributions of organisms, e.g. zooplankton, is critical for advancing our understanding. However, obtaining such data is challenging. First, both turbulent flows and planktonic motion are unsteady and three-dimensional, requiring a time-resolved, volumetric measurement system; second, plankton can propel themselves relative to the surrounding fluid leading to local differences in fluid and organism velocity; and third, many planktonic organisms have ...

Elastic turbulence, which is sensitive to geometry and polymer rheology, has shown great potential for improving the performance of mixing, heat transfer, and even oil recovery. Recent studies showed the importance of the rheological properties of polymer solutions on the onset of elastic turbulence. However, variations of rheological properties based on polymer sensitivities such as salinity and its corresponding effects on the elastic turbulence have not been revealed. This work investigated systematically the effects of salinity on the onset of elastic turbulence in both swirling flow and curvilinear microchannels. The variations of statistical properties, such as probability distribution functions (PDFs) and power spectral density of injected power (PSD), were analyzed for characterization. The onset conditions of elastic turbulence are postponed by high salinity, which is consistent with the mixing performance in a curvilinear microchannel. A salinity independent power-law exponent at a ...

Despite retention of the overall morphology, the cross-linked wormlike micelles exhibit unusual linear and nonlinear flow properties that presumably reflect the micelle stiffening upon cross-linking. Chemical fixation also influences their responses to changes in thermodynamic conditions. To ...

A multitude of consumer products, especially foods, owe their structure, stability and function to the presence of interfaces. Common examples include foams and emulsions such as milk, soups, salad dressings, mayonnaise, ice cream and butter (see McClements [1] and references therein). Although many of these foams and emulsions are thermodynamically unstable, the kinetics of phase separation can be controlled with the addition of various proteins, surfactants, gums and other stabilizing agents, which have very important implications for the shelf life of foods [2]. However, the presence of these additives often leads to complex rheological properties and gives rise to distinctive power laws in the creep response (i.e. the strain varies as γ(t)∼tα) and also in the corresponding frequency response (i.e. the elastic modulus varies with frequency as G′(ω)∼ωα). Such power-law responses are not well described by canonical rheological models such as the Maxwell or Kelvin-Voigt models [3]. ...

In my thesis, I studied three problems involving E. Coli bacterial suspensions. Firstly, I focused on the Brownian motion of passive tracers in this particular active suspension close to a surface. Buoyancy and non-buoyancy swimming solutions were tested, revealing a linear increase of the passive tracer diffusion with the active flux, obtained by the active concentration of bacteria multiplied by the mean velocity. Boundary confinements were also explored in buoyancy conditions, showing a better momentum transfer of the active bacteria as the height of the confinement gets smaller. The use of artificial swimmers instead of bacteria also leads to similar results in the enhancement of the diffusion. Secondly, I considered the modification of the fluid viscosity caused by the presence of these self-propelling entities. It is known that for pusher swimmers as bacteria the viscosity can even be smaller than that of the suspending fluid viscosity. The lack of experimental result showing this effect in the

CICECO Development of multifunctional plaster using nano-TiO2 and distinct particle size cellulose fibers
The present study reports on the development of multifunctional plaster showing superior thermal insulation, ability to control the indoor RH and NOx photocatalytic degradation. The plaster contains TiO2 nanoparticles (1 wt.%) and 0-4 wt.% fibers of two distinct sizes: 1 mm < d < 2 mm (Fb(1-2mm)) and 2 mm < d < 4mm (Fb(2-4mm)). The formulations were adjusted based on flow table and rheometer tests, aiming to assure a desirable workability. Plasters with similar workability (spread on table) showed distinct yield stress values over time and Fb((1-2mm)) plays an important role on the workability control. Rheological behaviour was governed by Fb((2-4mm)). Binary mixture 2.0Fb(1-2mm) + 2.0Fb(2-4mm)2.0Fb(2-4mm) required less water amount to show the same workability of the single formulation 4.0Fb(1-2mm). However, the control of the rheological behavior over time was found difficult. The apparent porosity, water absorption and capillary index were strongly incremented with the rise of cellulose fiber

Resistance to blood flow in microvessels in vivo. | Circulation ResearchResistance to blood flow in microvessels in vivo. | Circulation Research
Resistance to blood flow through peripheral vascular beds strongly influences cardiovascular function and transport to tissue. For a given vascular architecture, flow resistance is determined by the rheological behavior of blood flowing through microvessels. A new approach for calculating the contribution of blood rheology to microvascular flow resistance is presented. Morphology (diameter and length), flow velocity, hematocrit, and topological position were determined for all vessel segments (up to 913) of terminal microcirculatory networks in the rat mesentery by intravital microscopy. Flow velocity and hematocrit were also predicted from mathematical flow simulations, in which the assumed dependence of flow resistance on diameter, hematocrit, and shear rate was optimized to minimize the deviation between measured and predicted values. For microvessels with diameters below approximately 40 microns, the resulting flow resistances are markedly higher and show a stronger dependence on hematocrit ...

BLI - LAMMP - Seminar Video
Most of the materials, in general, are neither purely elastic nor purely viscous; they exhibits both elastic property (revealing its capability to store mechanical energy) and viscous property (manifesting its characteristic to dissipate energy, often in the form of heat). The study of the complex viscoelastic property of matter is known as rheology. Macro-rheology, or synonymously, classical rheometry, for the measurement of the bulk-average viscoelastic property of a material via a conventional rheometer often expresses the results in terms of either the magnitude of the complex viscosity｜*｜or both the real part () which is related to the elastic property and the imaginary part () which is related to the viscous property, both in the units of Pascal sec. (or poise; 1 poise = 0.1 Pa sec.), as a function of the shear rate. Likewise, micro-rheology allows us to probe the localized rheological properties of soft matter (often liquid) with one or more micron-size particles with a ...

Flow Properties of Lambda Carrageenan in Aqueous Systems. By Andrea Rivera del Rio, Mariana Ramírez-Gilly and Alberto Tecante. Small amplitude oscillatory and steady shear measurements at 25°C were used to investigate the rheological behavior of λ‐carrageenan solutions at pH 7.0 ± 1.0 without and with added sodium counterion. The dynamic moduli, G′(ω) and G″(ω), show the typical behavior of macromolecular solutions in which the viscous character predominates. The steady shear flow exhibits a Newtonian zero‐shear viscosity (η0) region followed by a shear‐thinning zone. Viscosity data can be well described by the Carreau‐Yasuda model. Without added Na+, the intrinsic viscosity, [η], and the critical overlap concentration, C*, are 204 dL/g and 0.21%, respectively. With 20 mmol/dm3 Na+, [η] = 14.7 dL/g and C* = 0.38%. For concentrations below C*, the viscous character is more sensitive to the presence of added Na+, and the opposite occurs when the concentration exceeds C*. The ...

Gel form of ECM-scaffold prepared from bovine Nucleus Pulposus. - InfoscienceGel form of ECM-scaffold prepared from bovine Nucleus Pulposus. - Infoscience
Decellularized tissues composed of extracellular matrix (ECM) and used as biologic scaffolds, have been shown to be useful for the repair of a variety of tissues. The clinical utility of such scaffolds for the tissue engineering of Nucleus Pulposus (NP) might be large but limited by the surgical procedure necessary to implant the engineered tissue. An injectable gel form of the ECM could potentially conform the required three-dimensional shape and could be delivered to site of interest by minimally invasive techniques. The goal of this project is to design a gel form of ECM scaffold, prepared from decellularized bovine NP that has been powdered. The work will include the evaluation of the gel to support in vitro growth of bovine NP-cells and the rheological characterization of its properties. Grimm, Alizée; Abdel-Sayed, Philippe

Evaluation of F127 / chitosan hydrogel as a scaffold for bone repair
An in situ gelled scaffold for bone tissue engineering to restore the function of bone tissues is developed. The gel is comprised of Pluronic F127 and chitosan. The gelation temperature (Tgel), and viscoelastic properties and mucoadhesive force of the systems were investigated by means of rheological analyses. At specific concentrations, the hydrogel exhibited a Tgel close to the body temperature due to the addition of chitosan. Mucoadhesion experiments showed a rheological synergism between F127/chitosan gels and mucin dispersion, and a change in the flow behavior. In vitro release results indicated that the optimized gel was able to prolong and control acyclovir release for more than 20 min. Based on cell proliferation assay, the gel exhibited biocompatibility for osteoblasts.

A method is presented to calibrate the transfer function for a fluid-filled compliant cylinder as a function of wavenumber and frequency. An air-filled compliant cylinder has a first linear array of force sensors coupled to the cylinders exterior surface. A turbulent flow field is generated in a fluid environment about the first linear array which generates an output indicative of pressure incident thereupon. A fluid-filled compliant cylinder identical in diameter to the air-filled compliant cylinder houses a second linear array of force sensors. A similar turbulent flow field is generated in the fluid environment about the fluid-filled complaint cylinder to generate an output indicative of pressure incident upon the second linear array. The ratio of outputs is indicative of the transfer function of the fluid-filled compliant cylinder. Each output can be further adjusted by a calibrated sensitivity of the corresponding first and second linear arrays. The method compensates for elastic scattered

OSA | Optical coherence tomography-based micro-particle image velocimetryOSA | Optical coherence tomography-based micro-particle image velocimetry
We present a new application of optical coherence tomography (OCT), widely used in biomedical imaging, to flow analysis in near-wall hydrodynamics for marine research. This unique capability, called OCT micro-particle image velocimetry, provides a high-resolution view of microscopic flow phenomena and measurement of flow statistics within the first millimeter of a boundary layer. The technique is demonstrated in a small flow cuvette and in a water tunnel.. © 2013 Optical Society of America. Full Article , PDF Article ...

Critical Physico-Chemical Parameters to Define Cohesive Properties of an Ophthalmic Viscosurgical Device (OVD) | IOVS | ARVO...Critical Physico-Chemical Parameters to Define Cohesive Properties of an Ophthalmic Viscosurgical Device (OVD) | IOVS | ARVO...
Purpose: : The aim of this study is to show a correlation between cohesive and rheologically measured properties for OVDs and also to show the existence of a transition interval in molecular masses where there is a gradual change from cohesive to dispersive behavior. Methods: : A number of formulations of sodium hyaluronate (HA) in phosphate buffer differing in concentration and molecular mass were made and characterized rheologically. All solutions were formulated to belong to the concentrated regime, i.e. above the critical concentration c* (Simha et al) for each molecular mass. Experimental data for sample formulations were compared to published data for some commercial formulations (Poyer et al). The oscillatory tests were performed in a Physica MCR 300 rheometer with a cone-plate arrangement (CP 25-1). The measurements were performed in the LVE (linear viscoelastic region) under controlled shear deformation (CSD). The elastic, G, and the viscous moduli, G, were analyzed as a function ...

Paste (rheology)Paste (rheology)
In physics, a paste is a substance that behaves as a solid until a sufficiently large load or stress is applied, at which point it flows like a fluid. In rheological terms, a paste is an example of a Bingham plastic fluid. Pastes typically consist of a suspension of granular material in a background fluid. The individual grains are jammed together like sand on a beach, forming a disordered, glassy or amorphous structure, and giving pastes their solid-like character. It is this "jamming together" that gives pastes some of their most unusual properties; this causes paste to demonstrate properties of fragile matter. Examples include starch pastes, toothpaste, mustard, and putty. In pharmacology, paste is a basic pharmaceutical form. It consists of a fatty base (e.g., petroleum jelly) and at least 25% of a solid substance (e.g., zinc oxide). Pharmaceutical pastes are typically intended for external application to the skin. They are usually thick and do not melt at physiologic temperatures. ...
