Modulation of distal colonic epithelial barrier function by dietary fibre in normal rats. (1/121)

BACKGROUND: Dietary fibre influences the turnover and differentiation of the colonic epithelium, but its effects on barrier function are unknown. AIMS: To determine whether altering the type and amount of fibre in the diet affects paracellular permeability of intestinal epithelium, and to identify the mechanisms of action. METHODS: Rats were fed isoenergetic low fibre diets with or without supplements of wheat bran (10%) or methylcellulose (10%), for four weeks. Paracellular permeability was determined by measurement of conductance and 51Cr-EDTA flux across tissue mounted in Ussing chambers. Faecal short chain fatty acid (SCFA) concentrations were assessed by gas chromatography, epithelial kinetics stathmokinetically, and mucosal brush border hydrolase activities spectrophotometrically. RESULTS: Body weight was similar across the dietary groups. Conductance and 51Cr-EDTA flux were approximately 25% higher in animals fed no fibre, compared with those fed wheat bran or methylcellulose in the distal colon, but not in the caecum or jejunum. Histologically, there was no evidence of epithelial injury or erosion associated with any diet. The fibres exerted different spectra of effects on luminal SCFA concentrations and pH, and on mucosal indexes, but both bulked the faeces, were trophic to the epithelium, and stimulated expression of a marker of epithelial differentiation. CONCLUSIONS: Both a fermentable and a non-fermentable fibre reduce paracellular permeability specifically in the distal colon, possibly by promoting epithelial cell differentiation. The mechanisms by which the two fibres exert their effects are likely to be different.  (+info)

Axon voltage-clamp simulations. I. Methods and tests. (2/121)

This is the first in a series of four papers in which we present the numerical simulation of the application of the voltage clamp technique to excitable cells. In this paper we describe the application of the Crank-Nicolson (1947) method for the solution of the parabolic partial differential equations that describe a cylindrical cell in which the ionic conductances are functions of voltage and time (Hodgkin and Huxley, 1952). This method is compared with other methods in terms of accuracy and speed of solution for a propagated action potential. In addition, differential equations representing a simple voltage-clamp electronic circuit are presented. Using the voltage clamp circuit equations, we simulate the voltage clamp of a single isopotential membrane patch and show how the parameters of the circuit affect the transient response of the patch to a step change in the control potential. The stimulation methods presented in this series of papers allow the evaluation of voltage clamp control of an excitable cell or a syncytium of excitable cells. To the extent that membrane parameters and geometrical factors can be determined, the methods presented here provide solutions for the voltage profile as a function of time.  (+info)

Axon voltage-clamp simulations. II. Double sucrose-gap method. (3/121)

This is the second in a series of four papers on the simulation of the voltage clamp of cylindrical excitable cells. In this paper we evaluate the double sucrose-gap voltage-clamp technique for the squid and lobster giant axons. Using the Crank-Nicolson method of solution of the cable equations and differential equations representing the voltage clamp circuit we studied the effect of length of the sucrose gap "node" on the voltage profile along an excitable cell during a simulated voltage clamp. The voltage gradients along the region of the cell within the node produce "notches" in the current recording as well as changes in the magnitude of the sodium and potassium current for a given voltage step. Our results show that good voltage clamp control requires node lengths less than one-half the axon diameter.  (+info)

Axon voltage-clamp simulations. A multicellular preparation. (4/121)

In this paper we extend the simulation of the voltage clamp of a single nerve fiber to a bundle of axons. These simulations included not only the description of the voltage clamp circuit and a single unidimensional cable to represent the preparation in the "node" region of a double sucrose gap used previously but also a series resistance and a shunt pathway. The output of the voltage control amplifier is applied across the membrane plus the series resistance, producing a voltage drop across the series resistance due to the current generated by the membrane in response to a depolarizing voltage step. Since the membrane current has an inward and an outward phase, voltage drops of opposite sign are produced across the series resistance. During the transient current and at all points along an axon, the potential deviation produced by the series resistance is opposite to the deviation produced by the longitudinal gradient. Only at a command potential equal to the sodium equilibrium potential, the membrane potential transiently matches the command potential. For the attempted voltage clamp of an axon, values of series resistance larger than 50 omega-cm2 allowed propagated action potentials in the membrane. In spite of the presence of propagated action potentials at the calbe membrane, the recorded current does not show "notches" and it has a phase of inward current and a phase of outward current. It is concluded that, in a multicellular preparation with series resistance, the recording of a square voltage pulse does not indicate voltage control of the transmembrane potential. The presence of a shunt pathway produces inaccurate values of current density. Neither series or shunt resistance produce "notches" in the current records.  (+info)

The interaction of DNA with dopamine by spectroscopic and electrochemical methods. (5/121)

It has recently been reported that dopamine may show some biological activities in antitumor and cell apoptosis. We have thoroughly investigated the interaction between dopamine and DNA by CD, UV, fluorescence and electrochemical methods. The results of spectroscopic measurements have indicated that a binding event occurs in a dopamine-DNA system. Besides the electronstatic interaction between a negatively charged DNA molecule and a positively charged dopamine molecule, other binding modes, such as hydrogen-bond and intercalation may also exist in this system. The interaction parameters, including the equilibrium constant and binding numbers, were estimated by an electrochemical method based on the redox current and formal potentials. Both of the two calculation methods showed that the 1:1 type of complex was formed in the dopamine-DNA system and that its equilibrium constant was about 5.85 x 10(6) M(-1). Based on the results of UV, fluorescence and electrochemical experiments in the present study, dopamine may be employed as an effective probe for a DNA assay.  (+info)

Spectroscopic and voltammetric study on the binding of aluminium(III) to DNA. (6/121)

Cyclic voltammetry (CV) and ultraviolet (UV) spectroscopy were used, for the first time, to study the interaction between aluminium(III) and calf thymus DNA under neutral pH conditions. Thus obtained data confirmed the existence of a relatively strong interaction between Al(III) and DNA. The binding site for aluminium(III) on DNA chains is not the bases, but the phosphate groups on the DNA backbones, the same as that for [Co(phen)3](3+/2+) that binds non-specifically and electrostatically to the deoxyribose phosphate backbone of DNA. When coexisting, Al(III) binds more favorably to DNA than [Co(phen)3](3+/2+), which implies the relatively strong binding of Al(III) to the phosphate backbone of DNA under neutral pH conditions. The nature of the binding of Al(III) to DNA is also discussed.  (+info)

Effect of polylysine on transformations and permeability of negative vesicular membranes. (7/121)

Small (40-60 nm in diameter) and large (300-350 nm) negative vesicles were complexed with a cationic polypeptide, poly-L-lysine (PL). Laser microelectrophoresis experiments showed that in small vesicles rendered anionic with the addition of cardiolipin (CL(2-)), only the CL(2-) in the outer leaflet is involved in the complexation with PL. Calorimetric and other data demonstrate that the binding of PL to the membrane surface causes domains ("rafts") of CL(2-) to form in the outer leaflet, and it is these domains that electrostatically bind the polymer. The kinetics of transmembrane permeation of doxorubicin (Dox, a fluorescent anti-tumor drug) was monitored with and without PL binding to the outer surface of the vesicles. It was found that PL mediates the permeation of Dox into the vesicle interior. In the absence of PL, the Dox molecule (possessing an amino group of pK(a)=8.6) binds to the anionic vesicles in the protonated form and, consequently, suffers an impaired mobility through the membrane. On the other hand, when the PL covers the vesicle surface, Dox passes though the membrane with greater ease. The effects of salt and polyanion on the stability of PL-vesicle complexes and the PL-mediated Dox permeation are also discussed.  (+info)

A disposable voltammetric cell for determining the titratable acidity in vinegar. (8/121)

A disposable voltammetric cell using three pencil leads as working, reference, and counter electrodes was developed for determining the titratable acidity, i.e. the acid content in vinegar. The materials of the pencil leads were graphite-reinforcement carbons (GRCs). A voltammetric determination of acid was made by measuring the reduction prepeak current of 3,5-di-t-butyl-1,2-benzoquinone (DBBQ) due to the presence of acids in unbuffered solution. The potential stability of the pseudo-reference electrode of GRC was examined. The prepeak current was found to be proportional to the acetic acid concentration from 0.05 to 2.7 mM with a correlation coefficient of 0.999. The cell-to-cell reproducibility for 1 mM acetic acid was evaluated with ten individual disposable cells. The RSD of the prepeak current and the SD of the prepeak potential were 2.56% and 0.008, respectively. The titratable acidity in five vinegar samples was determined by voltammetry using disposable cells and compared with that of the titratable acidity determined by the conventional potentiometric titration method. We then observed the results by both methods, and found a correlation coefficient of 0.972. As such, the voltammetry using disposable-cell required only one thousandth the volume of a vinegar sample for the titration method. The disposable cell was superior to the conventional electrochemical cell, in terms of facility, environment-friendly, and economy, and thus a sensor using the present cell would be useful for routine work in the quality control of vinegar.  (+info)

Unease-gelatin interdigitated microelectrodes for the conductometric determination of protease activityUnease-gelatin interdigitated microelectrodes for the conductometric determination of protease activity
Conductometric microbiosensors for the determination of trypsin were elaborated via the modification of microfabricated interdigitated gold electrodes by a cross-linked urease/BSA coating covered by a gelatin film. The resulting microelectrodes were exposed to different trypsin concentrations ranging from 100 pg/mL to 1 mg/mL (1 mU/mL to 10,000 U/mL) for selective proteolytic degradation of the gelatin film. Then, the conductometric response of the microbiosensors to urea (33 mu M) was recorded as a function of the trypsin concentration, the gelatin amount (8-80 ng) and the incubation time (40 s, 100 min). The optimum incubation time for each trypsin concentration was determined leading to a detection limit of 100 pg/mL (1 mU/mL). In these optimized conditions, the proof of concept of this sensitive, disposable, low-cost and label-free trypsin biosensors based on a conductometric transducer was demonstrated for the first time.

Microcontroller Action Potential Generator - jpralves.netMicrocontroller Action Potential Generator - jpralves.net
Here I demonstrate how to use a single microcontroller pin to generate action-potential-like waveforms. The output is similar my fully analog action potential generator circuit, but the waveform here is created in an entirely different way. A microcontroller is at the core of this project and determines when to fire action potentials. Taking advantage of the pseudo-random number generator (rand() in AVR-GCCs stdlib.h), I am able to easily produce unevenly-spaced action potentials which more accurately reflect those observed in nature. This circuit has a potentiometer to adjust the action potential frequency (probability) and another to adjust the amount of overshoot (afterhyperpolarization, AHP). I created this project because I wanted to practice designing various types of action potential measurement circuits, so creating an action potential generating circuit was an obvious perquisite.

2018 - English A validation of novel approach for diagnosis of cystic fibrosis (CF) is presented. The method is very simple and fast, since for collection of samples, only wiping of the skin of forearm is needed. The collected sample is analyzed by capillary electrophoresis with contactless conductometric detection (CE-C4D). Ion ratios are determined as ratios of peak area of chloride anion and peak areas of selected cations. It is possible to distinguish between cystic fibrosis patients and healthy individuals when ion ratio is applied as diagnostic factor.

Electrical detection and actuation of single biological cells with application to deformability cytometry for markerless...Electrical detection and actuation of single biological cells with application to deformability cytometry for markerless...
An all-electrical system is developed to actuate and detect single biological cells in a microfluidic channel for diagnostic applications. Interdigitated electrodes fabricated on the channel floor transfer a high frequency signal for capacitance detection and a low frequency signal for dielectrophoretic actuation. In the fluid-filled channel, a pressure-driven flow propels single biological cells, which induce time-dependent capacitance signatures as they pass over the electrodes. With a sub-attofarad (~0.15 aF RMS, 53 Hz bandwidth) capacitance resolution, this system detects biological cells (e.g., 1 yeast cell ~ 50 aF) and their deflections (1 micrometer ~ 5 aF) from exerted dielectrophoretic forces (, 5 pN). Electrical detection of cell actuation by strong DEP forces provides an avenue for both inducing and monitoring the deformation of viscoelastic cells. A strong and repulsive dielectrophoretic force can be used to press a biological cell into a channel wall. When this occurs, the ...

Microcontroller Action Potential Generator - SWHarden.comMicrocontroller Action Potential Generator - SWHarden.com
The core of this circuit is a capacitor which is charged and discharged by toggling a microcontroller pin between high, low, and high-Z states. In the high state (pin configured as output, clamped at 5V) the capacitor charges through a series resistor as the pin sources current. In the low state (pin configured as output, clamped at 0V) the capacitor discharges through a series resistor as the pin sinks current. In the high-Z / high impedance state (pin configured as an input and little current flows through it), the capacitor rests. By spending most of the time in high-Z then rapidly cycling through high/low states, triangular waveforms can be created with rapid rise/fall times. Amplifying this transient and applying a low-pass filter using a single operational amplifier stage of an LM-358 shapes this transient into something which resembles an action potential. Wikipedia has a section describing how to use an op-amp to design an active low-pass filter like the one used here.. ...

Chemiresistors (conductometric sensor) were fabricated on the basis of novel nanomaterials-silica nanosprings ALD coated with ZnO. The effects of high temperature and UV illumination on the electronic and gas sensing properties of chemiresistors are reported. For the thermally activated chemiresistors, a discrimination mechanism was developed and an integrated sensor-array for simultaneous real-time resistance scans was built. The integrated sensor response was tested using linear discriminant analysis (LDA). The distinguished electronic signatures of various chemical vapors were obtained at ppm level. It was found that the recovery rate at high temperature drastically increases upon UV illumination. The feasibility study of the activation method by UV illumination at room temperature was conducted.

The study investigated ingress of Cl- ions and their effects on the compressive strength development of a pozzolana based cement. The cement was made by blending Ordinary Portland Cement (OPC) with selected calcined clays. X-Ray Fluorescence (XRF), Atomic Absorption Spectroscopy (AAS) and flame photometry chemical analysis were carried out as a preliminary test to determine the chemical composition of the sampled clays. It was found that only one of the sampled clays had a sum of Al2O3, SiO2 and Fe2O3 above 70 percent. Sampled clays were activated at a temperature of 700 0C for one and two hours separately and also at 800 0C for one hour. Pozzolanicity test was carried out on the sampled clays using the conductometric method. Clays calcined at 800 0C for one hour exhibited the highest level of pozzolanicity. The calcined clay at 800 0C for one hour was blended with OPC at replacement levels of 25, 30, 35, 40, 45 and 50 percent by weight of the clay to make test cements labeled PCC25, PCC30, ...

The evidence for other neurobehavioural effects in volunteer studies, such as the effects on brain electrical activity, cognition, sleep, hypersensitivity and mood, is less clear. Generally, such studies have been carried out at exposure levels below those required to induce the effects described above, and have produced evidence only of subtle and transitory effects at best. The conditions necessary to elicit such responses are not well-defined at present.. Despite some scattered field-dependent changes, most notably in the alpha frequency band, and with intermittent exposure perhaps more effective than continuous exposure, these studies have produced inconsistent and sometimes contradictory results.. Generally, while electrophysiological considerations suggest that the central nervous system is potentially susceptible to induced electric fields; cognitive studies have not revealed any clear, unambiguous finding..

So, both the fleet owner and the persons sending or procuring the consignment have to sit keeping their fingers crossed till the fleet arrives. To track the path of the vehicle and to monitor the various parameters like fuel consumption, kilometers covered and the amount of load in the vehicle an intelligent device would come handy to solve the problem for the fleet operators and the clients. This paper aims at designing an intelligent device, which has two parts: the transmitter and the receiver. The transmitter is set up in the truck and it consists of a microcontroller to which the GPS and the GSM modem are connected. The analog signals from the transducers, which are used to detect the amount of load and the fuel in the truck, are sent to the microcontroller.

Patente WO1990005300A1 - Method for electrical detection of a binding reaction - Google PatentesPatente WO1990005300A1 - Method for electrical detection of a binding reaction - Google Patentes
A method is disclosed for detecting the occurrence of a binding or complex-forming reaction between specific substances by utilizing the binding reaction to modify an electrical circuit, and then measuring a change in the electrical state of the circuit. A diagnostic element (1D) useful in such a method includes a layer of a biogenic substance (30A), such as an antigenic (12A), coated onto a non-conductive base (22A) between a pair of electrical conductors (23A, 24A) superposed on the base (22A). Electrically conductive, metallic particles (14A) having antibody (15A) which reacts with the antigen (12A) bound thereto (15A), are added to the antigen layer (30A) deposited on the base (22A) and allowed to react therewith. Electrically conductive particles (14A) are thereby bound to the base (22A) due to the binding reaction between the antigen (12A) and antibody (15A) to thereby form aggregates (35A) of electrically conductive particles (14A) which modify the circuit.

This would work, but there are two issues. First, unless you happen to have a 1.25 V source available, this isnt useful. Second, we have one more choice to make. This circuit is only one of many possible solutions. Note that we only determined the ratio of R1 and R2, not their absolute value. R1 and R2 can both be scaled by the same factor to yield other equally valid circuits. There are several ways to look at what this choice means. One way is to decide the maximum current this circuit draws from your input voltage. With a A/D however, the most relevant choice is probably that the output have some minimum impedance. Lets say the A/D requires its input signal to be 10 kΩ or less. That means the parallel combination of R1 and R2 would need to be 10 kΩ. That comes out to R1 = 130 kΩ and R2 = 10.8 kΩ.. Now we have the circuit basically solved, except that it requires a inconvenient voltage source. Note that the voltage source and R2 together can be thought of as a Thevenin source. We can ...

Compression of electronic tongue data based on voltammetry - A comparative studyCompression of electronic tongue data based on voltammetry - A comparative study
In this paper, three data compression methods are investigated to determine their ability to reduce large data sets obtained by a voltammetric electronic tongue without loss of information, since compressed data sets will save data storage and computational time. The electronic tongue is based on a combination of non-specific sensors and pattern recognition tools, such as principal component analysis (PCA). A series of potential pulses of decreasing amplitude are applied to one working electrode at a time and resulting current transients are collected at each potential step. Voltammograms containing up to 8000 variables are subsequently obtained. The methods investigated are wavelet transformation (WT) and hierarchical principal component analysis (HPCA). Also, a new chemical/physical model based on voltammetric theory is developed in order to extract interesting features of the current transients, revealing different information about species in solutions.

Sensors | Free Full-Text | Portable Electronic Tongue Based on Microsensors for the Analysis of Cava WinesSensors | Free Full-Text | Portable Electronic Tongue Based on Microsensors for the Analysis of Cava Wines
Cava is a quality sparkling wine produced in Spain. As a product with a designation of origin, Cava wine has to meet certain quality requirements throughout its production process; therefore, the analysis of several parameters is of great interest. In this work, a portable electronic tongue for the analysis of Cava wine is described. The system is comprised of compact and low-power-consumption electronic equipment and an array of microsensors formed by six ion-selective field effect transistors sensitive to pH, Na+, K+, Ca2+, Cl−, and CO32−, one conductivity sensor, one redox potential sensor, and two amperometric gold microelectrodes. This system, combined with chemometric tools, has been applied to the analysis of 78 Cava wine samples. Results demonstrate that the electronic tongue is able to classify the samples according to the aging time, with a percentage of correct prediction between 80% and 96%, by using linear discriminant analysis, as well as to quantify the total acidity, pH, volumetric

Two different azo molecules functionalized graphene oxide (GO) through an ester linkage have been synthesized for the first time. Chemical structure of the azo-GO hybrids was confirmed by Fourier transform infrared spectroscopy and UV-visible spectroscopy. The GO functionalized with 5-((4-methoxyphenyl)azo)-salicylaldehyde was further characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM). The SEM studies demonstrated that the morphology of the azo-GO hybrid was found to be similar to the GO sheets but slightly more wrinkled. Further, TEM image of azo-GO indicates some dark spots on the GO sheets due to azo functionalization. AFM results also reveal that the azo functionalization increases the thickness of GO sheet to 4-5 nm from 1.2-1.8 nm. Both the azo-hybrids show absorption band around 379 nm due to the $Ï€$-$Ï€$* transition of the trans azo units. Photoluminescence spectra of azo-GO hybrids show a strong ...

Electroanalytical ChemistryElectroanalytical Chemistry
Electroanalytical methods are a class of facility in analytical chemistry, which study an analyte by calibrating the potential (volts) and/or power (amperes) in an electrochemical cell containing the analyte. The three main divisions are potentiometry (the difference in electrode potentials is calibrated), coulometry (the cells current is measured over time), and voltammetry (the cells current is measured while strongly altering the cells potential). A sensor is equipment that detects and reacts to some type of input from the physical environment. A biosensor is an analytical apparature, used for the exposure of an analyte that combines a biological compound with a physicochemical detector. The sensitive biological components e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc. is a biologically borrowed material or biomimetic component that interacts binds or recognizes) with the analyte under study.

Determination of the Charge Density of Anionic PolyacrylamideDetermination of the Charge Density of Anionic Polyacrylamide
Although there are starch based flocculants available, it is the various polyacrylamide compounds that are most commonly used in the mining and petroleum industries. It is primarily used as a method for enhancing the sedimentation of solids in the water treatment processes as well as a mobility control agent in enhanced oil recovery processes. It is most commonly the non-ionic and anionic polyacrylamide compounds which are used in these industries. The charge density of the polyacrylamide will have an effect on its efficacy in these given implementations. There are a number of methods which are traditionally used to determine the carboxylate content of the polyacrylamide. They are conductometric and potentiometric titrations as well as infrared spectroscopy. However, the titration methods are time consuming and the infrared spectroscopy is limited by poorly resolved spectra of carboxylate carbonyl and the amide carboxyl adsorption peaks.. W.M Leung, D.E. Axelson and D. Syme have proposed ...

reaction mechanism - React these iron oxide, ammonium nitrate, and sucrose - Chemistry Stack Exchangereaction mechanism - React these iron oxide, ammonium nitrate, and sucrose - Chemistry Stack Exchange
Two questions: what reaction forms between ammonium nitrate, black iron oxide, and sucrose; and a story related question.. So heres the whole story:. So I was playing around a few months ago and stumbled upon a mixture that generated something similar to Black Snakes (firework). I recently decided to demo this mixture to someone, but I could not find my notes about the experiment, so I decided to try to replicate the mixture from what I remembered.. I am certain that the mixture contained ammonium nitrate, black iron oxide, and some sort of fuel (probably sucrose, impure in the form of powdered sugar). Combining these three ingredients (one part by volume, whatever particle sizes I have), and igniting with a lighter, the mixture does form black snaking ash, and turns red and crumbles as it cools.. Q1: So, what kind of reaction has taken place between the black iron oxide, ammonium nitrate, and sucrose?. If I leave out any one of the ingredients, the ash snake does not form, so all three ...

With the growth of smart sensors being part of everyones everyday life, data driven applications are acquiring more and more relevance in the electronics consumer market. Smartwatches for fitness tracking, camera for security and multimedia entertaining as well as biomedical devices as ECG and EEG wearable devices for health care applications are just few of these examples. Typically, the data streams coming from sensors are processed on servers in the cloud. This requires the data to be sensed by a physical device driven by a microcontroller, possibly pre-processed and eventually sent to the network wirelessly (as using Bluetooth low power WiFi radios) where the packet goes through router and switches until it finally arrives to the server in the cloud which will process it and possibly give feedbacks to the users or to the microcontroller for closed-loop applications. As these smart-sensors are usually battery-powered, they are designed to be energy efficient. Most of the power is spent in ...

Im only loosely involved in 802.15.4 projects for now, and not actively following the latest developments and standards. Having said that, a friend of mine has gotten involved in creating small, wireless modules called RadioBlocks.. They use an IEEE 802.15.4 radio combined with a small ARM Cortex-M0 microcontroller. They use an open-source mesh networking software we created called SimpleMesh, so most of my recent work on 802.15.4 has been around this project. The mesh software is designed to do the basic job of sending a block of data to another node, and otherwise staying out of the way. I previously did a lot of work using IPv6 on such small sensor networks, but havent been active in that area lately.. At Dalhousie, Im working on the area of side-channel analysis of cryptographic systems, specifically power analysis.

Robert] wanted more out of his GE Color Effects G-35 LED Christmas lights. He reverse engineered and then hacked the protocol the lights use to communicate so that he can control each bulb. A 26-bit frame contains a 6-bit address, an 8-bit brightness value, and a 12-bit color value. The daisy chain topology of the data bus allows for modular bulbs with addresses enumerated during the startup of the string of lights. With this information, a 5 volt capable microcontroller is able to control a whole string of these lights with a refresh rate of up to 24Hz. In this case, [Robert] used an ATtiny13A microcontroller to control the string of lights. You can see a video of them in action after the break.. Also taken apart and analyzed, were the wireless transmitter and receiver that came with the lights, revealing a cheap ISM band receiver and transmitter module pair. Perhaps they will be useful for another project. We look forward to seeing people put these hacked lights to use throughout the ...

Abstract: A novel ultrasonic technique (sampled cw method) is used to probe into the viscosity of vortex systems in untwinned and twinned YBCO single crystals. Motion of the flux lines in the superconducting sample is induced via coupling with the moving ionic lattice in the bulk of the sample. Hence, the observed dissipation has its origin in the (induced) motion of the vortices with respect to the ionic background of conduction charge carriers. In the experiments which were performed, pronounced field-dependent attenuation changes were observed which are indicative of transitions from a soft vortex system at low fields to a rigid vortex system at high fields.

In this study we present a novel silver complex of hyaluronan-lipoate (SHLS12) in a gel-state form. NMR analysis, conductometry and elemental analysis demonstrated stable non-covalent interactions between silver ions and the polysaccharide-lipoate backbone, whereas rheological investigations confirmed its gel-like physical-chemical behavior. Biological studies showed the ability of SHLS12 to exert a straightforward activity against different bacterial strains grown in sessile/planktonic state. The biocompatibility was also proved toward two eukaryotic cell lines. By considering both its ability to preserve antibacterial properties when exposed to the serum protein BSA and its low susceptibility to be degraded by hyaluronidase enzyme, this novel complex may be considered as a promising biomaterial for future in vivo applications.. ...

Imagine a force F acting on some object at a distance r from its axis of rotation. We can break up the force into tangential (Ftan), radial (Frad) (see Figure 1). (This is assuming a two-dimensional scenario. For three dimensions -- a more realistic, but also more complicated situation -- we have three components of force: the tangential component Ftan, the radial component Frad and the z-component Fz. All components of force are mutually perpendicular, or normal.) From Newtons Second Law, Ftan = m atan However, we know that angular acceleration ...
