Nitrilase of Rhodococcus rhodochrous J1. Conversion into the active form by subunit association. (1/19)

Nitrilase-containing resting cells of Rhodococcus rhodochrous J1 converted acrylonitrile and benzonitrile to the corresponding acids, but the purified nitrilase hydrolyzed only benzonitrile, and not acrylonitrile. The activity of the purified enzyme towards acrylonitrile was recovered by preincubation with 10 mM benzonitrile, but not by preincubation with aliphatic nitriles such as acrylonitrile. It was shown by light-scattering experiments, that preincubation with benzonitrile led to the assembly of the inactive, purified and homodimeric 80-kDa enzyme to its active 410-kDa aggregate, which was proposed to be a decamer. Furthermore, the association concomitant with the activation was reached after dialysis of the enzyme against various salts and organic solvents, with the highest recovery reached at 10% saturated ammonium sulfate and 50% (v/v) glycerol, and by preincubation at increased temperatures or enzyme concentrations.  (+info)

Hyper-inducible expression system for streptomycetes. (2/19)

Streptomycetes produce useful enzymes and a wide variety of secondary metabolites with potent biological activities (e.g., antibiotics, immunosuppressors, pesticides, etc.). Despite their importance in the pharmaceutical and agrochemical fields, there have been no reports for practical expression systems in streptomycetes. Here, we developed a "P(nitA)-NitR" system for regulatory gene expression in streptomycetes based on the expression mechanism of Rhodococcus rhodochrous J1 nitrilase, which is highly induced by an inexpensive and safe inducer, epsilon-caprolactam. Heterologous protein expression experiments demonstrated that the system allowed suppressed basal expression and hyper-inducible expression, yielding target protein levels of as high as approximately 40% of all soluble protein. Furthermore, the system functioned in important streptomycete strains. Thus, the P(nitA)-NitR system should be a powerful tool for improving the productivity of various useful products in streptomycetes.  (+info)

Effect of high hydrostatic pressure on the barrier properties of polyamide-6 films. (3/19)

Little is known about the barrier properties of polymer films during high pressure processing of prepackaged foods. In order to learn more about this, we examined the influence of high hydrostatic pressure on the permeation of raspberry ketone (dissolved in ethanol/water) through polyamide-6 films at temperatures between 20 and 60 degrees C. Permeation was lowered by increasing pressure at all temperatures. At 23 degrees C, the increasing pressure sequence 0.1, 50, 100, 150, and 200 MPa correlated with the decreasing permeation coefficients P/(10(9) cm(2) s-1) of 6.2, 3.8, 3.0, 2.2, and 1.6. Analysis of the permeation kinetics indicated that this effect was due to a reduced diffusion coefficient. Pressure and temperature acted antagonistically to each other. The decrease in permeation at 200 MPa was compensated for by a temperature increase of 20 degrees C. After release of pressure, the former permeation coefficients were recovered, which suggests that this 'pressure effect' is reversible. Taken together, our data revealed no detrimental effects of high hydrostatic pressure on the barrier properties of polymer films.  (+info)

A new method for measuring free drug concentration: retinal tissue as a biosensor. (4/19)

PURPOSE: To develop a method of using isolated rat retina as a biosensor in experiments on controlled drug release for measuring the resultant concentration of free model drug in living tissue and for testing the biocompatibility of the polymers and polymeric nanostructures used as drug carriers. METHODS: The method is based on the monotonic dependence of the photoresponse kinetics of retinal rods on the concentration of the membrane-permeable phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (IBMX). Changes in the time to peak (tp) of linear-range rod photoresponses were followed by transretinal ERG mass potential recordings in the aspartate-treated, dark-adapted rat retina. The dependence of tp on [IBMX] was measured, and the calibration curve thus obtained was used to determine the amount of IBMX released from polymeric structures. The biocompatibility of the carrier was first assessed by the degree to which rods retained stable function in the presence of the polymer or monomers alone. RESULTS: The dependence of tp on [IBMX] was well-described by a second-order polynomial. After each change of [IBMX], a new equilibrium state was reached within 6 to 9 minutes, depending on temperature. The amounts of IBMX released from biocompatible polymeric structures were measurable with good accuracy in the range 10 to 300 microM. CONCLUSIONS: This method enables accurate concentration determinations of the model drug IBMX in retinal tissue in drug-release experiments. The concentration dependence of the photoresponse kinetics has to be calibrated for each retina and temperature. The same preparation can be used for rapid testing of possible bioincompatibility of various molecules.  (+info)

Temperature limit values for touching cold surfaces with the fingertip. (5/19)

OBJECTIVES: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. METHODS: Data were collected in four laboratories with a total of 20 males and 20 females performing a grand total of 1655 exposures. Each touched polished blocks of aluminium, stainless steel, nylon-6 and wood using the distal phalanx of the index finger with a contact force of 1.0, 2.9 and 9.8 N, at surface temperatures from +2 to -40 degrees C for a maximum duration of 120 s. Conditions were selected in order to elicit varying rates of skin cooling upon contact. Contact temperature (TC) of the fingertip was measured over time using a T-type thermocouple. RESULTS: A database obtained from the experiments was collated and analysed to characterize fingertip contact cooling across a range of materials and surface temperatures. The database was subsequently used to develop a predictive model to describe the contact duration required for skin contact temperature to reach the physiological criteria of onset of pain (15 degrees C), onset of numbness (7 degrees C) and onset of frostbite risk (0 degrees C). CONCLUSIONS: The data reflect the strong link between the risk of skin damage and the thermal properties of the material touched. For aluminium and steel, skin temperatures of 0 degrees C occurs within 2-6 s at surface temperatures of -15 degrees C. For non-metallic surfaces, onset of numbness occurs within 15-65 s of contact at -35 degrees C and onset of cold pain occurs within 5 s of contact at -20 degrees C. The predictive model subsequently developed was a non-linear exponential expression also reflecting the effects of material thermal properties and initial temperature. This model provides information for the protection of workers against the risk of cold injury by establishing the temperature limits of cold touchable surfaces for a broad range of materials, and it is now proposed as guidance values in a new international standard.  (+info)

High-yield activation of scaffold polymer surfaces to attach cell adhesion molecules. (6/19)

Zirconium tetra(tert-butoxide) reacts with surface amide groups of polyamide nylon 6/6 to give (eta(2)-amidate)zirconium complexes in high yield. These surface complexes react to bond the cell-adhesive peptide arginine-glycine-aspartic acid (RGD) to the polymer surface. A surface loading of 0.18 nmol/cm(2) of RGD is achieved, which is 20-1000 times higher than previously reported attainable on natural or synthetic polymers by other strategies. Approximately 40% of the nylon surface is covered by the RGD, which gives a surface that is both stable to hydrolysis and highly active for cell adhesion and spreading in vitro.  (+info)

Nylon-6 capillary-channeled polymer fibers as a stationary phase for the mixed-mode ion exchange/reversed-phase chromatography separation of proteins. (7/19)

Capillary-channeled polymer (C-CP) fibers extruded from nylon-6 are used as the stationary phase for the ion-exchange/reversed-phase mixed-mode chromatographic separation of a three protein mixture. The nylon-6 C-CP fibers are packed collinearly in a 250 x 1.5-mm i.d. column with an interstitial fraction of approximately 0.6. The effects of four displacing salts at three different pHs are studied with regards to protein retention time, peak width, selectivity, and resolution for a synthetic mixture consisting of myoglobin, ribonuclease A, and lysozyme to determine the optimum mobile phase conditions. The net charge model is found to be inadequate in fully explaining the retention behavior, as the proteins are retained by anion and cation-exchange interactions, as well as hydrophobic interactions with the stationary phase. It is found that pH and displacing salt strength had a significant influence on the retention properties and resolution of the proteins.  (+info)

Flixborough disaster - WikipediaFlixborough disaster - Wikipedia
The chemical works, owned by Nypro UK (a joint venture between Dutch State Mines (DSM) and the British National Coal Board (NCB)) had originally produced fertiliser from by-products of the coke ovens of a nearby steelworks. Since 1967, it had instead produced caprolactam, a chemical used in the manufacture of nylon 6.[a] The caprolactam was produced from cyclohexanone. This was originally produced by hydrogenation of phenol, but in 1972 additional capacity was added, built to a DSM design in which hot liquid cyclohexane was partially oxidised by compressed air. The plant was intended to produce 70,000 tpa (tons per annum) of caprolactam but was reaching a rate of only 47,000 tpa in early 1974. Government controls on the price of caprolactam put further financial pressure on the plant.[2] It was a failure of the cyclohexane plant that led to the disaster. A major leak of liquid from the reactor circuit caused the rapid formation of a large cloud of flammable hydrocarbon. When this met an ignition ...

A series of sidearm functionalized bisoxazoline ligands has been synthesized by reaction of the monolithiated methyl{bis(oxazolinyl)}methane with the appropriate electrophiles, and tested in the copper catalyzed asymmetric allylic oxidation of cyclohexene (Kharasch-Sosnovski reaction). The observed enantioselectivities were higher (up to 85% ee) than for the unfunctionalized bisoxazoline (BOX) derivatives (ca. 60% ee). Regardless of the functional groups incorporated into the sidearm unit, the ees obtained for the different derivatives were essentially indistinguishable. This implies that the sidearms do not interfere directly in this reaction and only play an indirect role by virtue of their steric demand. Three of the copper complexes have been characterized by X-ray diffraction, establishing a distorted octahedral coordination geometry around the copper atom in all three cases. In the elongated distorted CuN2O4 octahedra, the two nitrogen atoms of the oxazolines and one oxygen atom of ...

Nanostructuring organic polymers and organic/inorganic hybrid materials and controlling blend morphologies at the molecular level are the prerequisites for modern electronic devices including biological sensors, light emitting diodes, memory devices and solar cells. To achieve all-around high performance, multiple organic and inorganic entities, each designed for specific functions, are commonly incorporated into a single device. Accurate arrangement of these components is a crucial goal in order to achieve the overall synergistic effects. We describe here a facile methodology of nanostructuring conjugated polymers and inorganic quantum dots into well-ordered core/shell composite nanofibers through cooperation of several orthogonal non-covalent interactions including conjugated polymer crystallization, block copolymer self-assembly and coordination interactions. Our methods provide precise control on the spatial arrangements among the various building blocks that are otherwise incompatible with one

Polymer recycle has been practiced as part of the manufacturing process for nylon-6,6 (219) and nylon-6 (220) almost from the beginning of the iadustry. Acid hydrolysis by Du Pont and base hydrolysis by BASF and Rhc ne-Poulenc of relatively pure nylon-6,6 waste streams, followed by separation of iagredients, purification, and reuse, has been practiced for many years. Also, phosphoric acid-cataly2ed hydrolysis and steam distillation of caprolactam from pure nylon-6 is still used by BASF, Rhc ne-Poulenc, and SNIA. However, it is the challenge of recycling post-consumer waste that has generated the greatest activity siace 1990. Stimulated by more stringent governmental regulations for recycling plastic packagiag and automotive plastic components la Germany and the growing landfill problem ia the United States, the nylon iadustry has developed several technologies to address the issue of recycling post-consumer waste. One of the greatest economic challenges is the collection and separation of nylon ...

We present a new and efficient strategy for the atom-economic transformation of both alkynes and allenes to allylic functionalized structures via a Rh-catalyzed isomerization/addition reaction which has been developed in our working group. Our methodology thus grants access to an important structural class valued in modern organic chemistry for both its versatility for further functionalization and the potential for asymmetric synthesis with the construction of a new stereogenic center. This new methodology, inspired by mechanistic investigations by Werner in the late 1980s and based on preliminary work by Yamamoto and Trost, offers an attractive alternative to other established methods for allylic functionalization such as allylic substitution or allylic oxidation. The main advantage of our methodology consists of the inherent atom economy in comparison to allylic oxidation or substitution, which both produce stoichiometric amounts of waste and, in case of the substitution reaction, require ...

Alternative modes of Inheritance: Cytoplasmic, Maternal and Extra nuclear InheritanceAlternative modes of Inheritance: Cytoplasmic, Maternal and Extra nuclear Inheritance
In Paramecium, small granular particles are present in the cytoplasm called as kappa particles. Kappa particles produce a protein called paramecin that kills the sensitive strain without kappa particles. The strain with the kappa particles is called as killer/resistant strain and the other strain is called as sensitive strain. Gene responsible for producing kappa particles is present in homozygous or heterozygous dominant condition in killer strain while it is present in recessive form in sensitive strain. Paramecium reproduces both by sexual and asexual mode. During asexual reproduction, when conditions favour the cells undergo cell division while the kappa particles cannot divide at the same rate. Therefore the daughter cells receive less number of kappa particles and after few generations there can be complete loss of kappa particles. In this situation, strains with dominant alleles remain without any kappa particles. This proves the gene for kappa particles can only help in multiplication of ...

boulez elude: BASF Q2 profit dips amid patchy global economyboulez elude: BASF Q2 profit dips amid patchy global economy
FRANKFURT, Germany (AP) ? Chemicals and oil company BASF SE warned Thursday that it will find it more difficult to achieve its full-year profit target as it reported a 4.2 percent fall in second-quarter earnings due to weaker demand in an uneven global economy.. Following the warning, BASF shares fell 4 percent to 67.09 euros in morning trading in Frankfurt.. Net profit fell 4.2 percent to 1.16 billion euros ($1.53 billion) even as revenues rose 2.9 percent to 18.35 billion euros.. The company, based in Ludwigshafen, Germany, said it saw thinner profit margins on some products in its basic chemicals division such as caprolactam, the raw material for a widely used form of nylon that goes into everything from lingerie to tires.. It also said its business in more extensively processed chemical products saw intense competition in some product lines. That division also saw euro earnings reduced by a weaker yen, while its year-earlier earnings were boosted by insurance payments for damage suffered ...

The influence of fiber orientation and mold geometry variations on the reactive polymerization of ?-caprolactam during the mold filling phase in reactive processing is depicted in this work with the help of Computational Fluid Dynamics (CFD). Therefore the established Malkin kinetics is employed to describe the polymerization process combined with a model that correlates the viscosity of the reactive mixture with the local polymer conversion. To account for the reinforcing textile elements used for production of lightweight parts and the corresponding effects on the injection process, an approach is presented to correctly depict arbitrary fiber orientations within the cavity. Application of these models in CFD enables us to simulate the injection process for complex geometries and varying fiber orientations. Main focus lies on the identification of variations of the flow patterns and local alterations of the polymer conversion induced by different geometry elements and fiber orientations at ...

Enzymes catalyze a plethora of chemical reactions in nature. These biocatalysts offer a variety of benefits that no other synthetic catalyst can offer: high turnover, regio- and stereoselectivity, and ability to work under mild conditions and to react in environmentally friendly manufacturing processes. However, enzymes are not normally optimally suited for industrial applications. It is important to improve their properties to enable their more efficient application in an industrial setting, while also expanding the range of potential chemical reactions that they can catalyze. In this review, we focus our analysis on structural features and mechanisms of different enzymes that contain a pyridoxal-5′-phosphate (PLP) cofactor and that have noteworthy potential as biocatalysts in a variety of industries and applications. The selected PLP enzymes are ω-transaminases, lysine decarboxylase, threonine aldolase, L-tyrosine phenol-lyase, α-amino-ε-caprolactam racemases, and cystathionine β-lyase. ...

The study compared the biosensing properties of laccase biosensors based on carbon nanofibers (CNFs) and copper/carbon composite nanofibers (Cu/CNFs). The two kinds of nanofibers were prepared by electrospinning and carbonization under the same conditions. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy were employed to investigate the morphologies and structures of CNFs and Cu/CNFs. The amperometric results indicated that the Cu/CNFs/laccase(Lac)/Nafion/glass carbon electrode (GCE) possessed reliable analytical performance for the detection of catechol. The sensitivity of the Cu/CNFs/Lac/Nafion/GCE reached 33.1 μA/mM, larger than that of CNFs/Lac/Nafion/GCE. Meanwhile, Cu/CNFs/Lac/Nafion/GCE had a wider linear range from 9.95 × 10−6 to 9.76 × 10−3 M and a lower detection limit of 1.18 μM than CNFs/Lac/Nafion/GCE. Moreover, it exhibited a good repeatability, reproducibility, selectivity and long-term stability, revealing that electrospun Cu/CNFs have great

Handmade cloning (HMC) has been used to generate transgenic pigs for biomedical research. Recently, we found that parthenogenetic activation (PA) of porcine oocytes and improved HMC efficiency could be achieved by treatment with sublethal high hydrostatic pressure (HHP). However, the molecular mechanism underlying the effects of HHP treatment on embryonic development is poorly understood and so was investigated in the present study. Thus, in the present study, we undertook genome-wide gene expression analysis in HHP-treated and untreated oocytes, as well as in 4-cell and blastocyst stage embryos derived by PA or HMC. Hierarchical clustering depicted stage-specific genomic expression profiling. At the 4-cell and blastocyst stages, 103 and 163 transcripts were differentially expressed between the HMC and PA embryos, respectively (P , 0.05). These transcripts are predominantly involved in regulating cellular differentiation, gene expression and cell-to-cell signalling. We found that 44 transcripts ...

The effects of high hydrostatic pressure on microfilaments and microtubules in Xenopus laevis | DevelopmentThe effects of high hydrostatic pressure on microfilaments and microtubules in Xenopus laevis | Development
Xenopus laevis embryos of stages 14-20 were subjected, for periods of 5-330 min, to hydrostatic pressures ranging from 500 to 10000 psi. The specimens were fixed under corresponding pressures and their neuroepithelium was studied under light and electron microscopy. A pressure of 3000 psi, maintained for as long as 180 min, did not inhibit neurulation though it induced slight deformities of the neuroepithelium. A pressure of 4000 psi, applied for 180 min, disrupted the apical ring of microfilaments and blocked neurulation. The cells lost their dissymmetry. The effect was reversible. Lengthening the duration of treatment to 330 min caused the neuroepithelial cells to loose their microtubules and to become round. This situation was not reversible. Our results indicated that microfilaments are more sensitive than microtubules, that both organelles became increasingly sensitive as the exerted pressure was increased and that microtubules of older embryos exhibited a better resistance. Finally, we ...

Analytical MethodsAnalytical Methods
Extractables can be diverse. No single analytical method can detect all extractables, so multiple orthogonal methods must always be used. The table below summarizes analytical techniques and their ability to detect diverse chemical entities extracted from materials.. Liquid chromatography and gas chromatography are two analytical separation techniques that, when applied together, provide the ability to detect diverse extractables. The use of alternate sample introduction techniques (e.g. headspace analysis) and detectors (e.g. flame ionization detector) increases the range of detectable extractables.. In addition, sample modification techniques can provide the ability to more effectively detect specific types of extractables. For example, organic acids are often more easily detected by GC following sample derivatization.. The different techniques employed by VR Analytical are briefly described below. When a combination of these techniques is applied, a more complete characterization of the ...

Scientists: Oxygen & Nitrogen Radiatively Important Greenhouse Gases With IR Absorption Temps Similar To CO2Scientists: Oxygen & Nitrogen Radiatively Important Greenhouse Gases With IR Absorption Temps Similar To CO2
A real-world experiment (Allmendinger, 2016) assessing the efficacy of CO2s IR-absorption temperature capacity relative to air (N2, O2) and Argon (Ar) further establishes CO2 is not the special GHG it is commonly thought to be.. Twin styrofoam Saran-wrap-sealed tubes exposed to sunlight were used, one with pure (1,000,000 ppm) CO2 and the other with air (N2, O2) and/or Ar.. The results were admittedly surprising given expectations CO2 would operate as a radiatively distinct GHG.. The tube absorbing IR with N2 and O2 (air) and Ar warmed to a temperature limit quite similar to (55°C to 58°C) the temperature limit in the 100% CO2 tube (58°C).. There was no remarkable or special heat absorption capacity for CO2 relative to air observed. And Argon - not considered a greenhouse gas - absorbed IR to the same temperature limit as CO2. With a concentration of 9300 ppm, Ar is the third-most abundant gas in the Earths atmosphere.. Because there is so little to distinguish CO2 from the most ...

Batch processiag of nylon-6 is generally used only for the production of specialty polymers such as very high molecular weight polymer or master batch polymers for special additives. In a typical modem batch process (147-150), the caprolactam is mixed ia a hoi ding tank with the desired additives and then charged to an autoclave with a small amount (2-4%) of water. During the two-stage polymeriza tion cycle, the temperature is raised from 80 to 260°C. In the first stage, water is held ia the reactor, the pressure rises, and the hydrolysis and addition steps occur. After a predetermined time the pressure is releasedand the final condensation reaction step occurs. The molecular weight of the polymer can be iacreased by means of a vacuum finishing step, if desired. The entire process can take three to five hours. The final polymer is then drained, often with a forcing pressure of iaert gas, through a die to form ribbons of polymer, which are then cooled ia water and cut iato pellets. Because ...

Cyclohexanone oxime is used primarily as a captive intermediate in the synthesis of caprolactam for the production of polycaprolactam (Nylon-6) fibers and plastics and also in a variety of industrial applications. Cyclohexanone oxime was selected for study because of the potential for human exposure and the interest in oximes as a chemical class. Toxicity studies of cyclohexanone oxime (approximately 99% pure) were carried out in male and female B6C3F1 mice; the compound was administered in drinking water for 2 weeks or 13 weeks. In addition, the genetic toxicity of cyclohexanone oxime was evaluated by determining mutagenicity in Salmonella typhimurium and induction of chromosomal aberrations in cultured Chinese hamster ovary cells in vitro, with and without S9 activation.

Nylon - WikipediaNylon - Wikipedia
Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films or shapes. Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1930. The first example of nylon (nylon 6,6) was produced using diamines on February 28, 1935, by Wallace Carothers at DuPonts research facility at the DuPont Experimental Station. In response to Carothers work, Paul Schlack at IG Farben developed nylon 6, a different formulation based on caprolactam, on January 29, 1938. Nylon was first used commercially in a nylon-bristled toothbrush in 1938, followed more famously in womens stockings or nylons which were shown at the 1939 New York Worlds Fair and first sold commercially in 1940. During World War II, almost all nylon production was diverted to the military for use in parachutes and parachute cord. Wartime uses of ...

DNA topoisomerases are enzymes that control DNA topology and are vital targets for antimicrobial and anticancer drugs. Here we present a mass spectrometry study of complexes formed between the A subunit of the topoisomerase DNA gyrase and the bifunctional inhibitor simocyclinone D8 (SD8), an antibiotic isolated from Streptomyces. These studies show that, in an alternative mode of interaction to that found by X-ray crystallography, each subunit binds a single bifunctional inhibitor with separate binding pockets for the two ends of SD8. The gyrase subunits form constitutive dimers, and fractional occupancies of inhibitor-bound states show that there is strong allosteric cooperativity in the binding of two bifunctional ligands to the dimer. We show that the mass spectrometry data can be fitted to a general model of cooperative binding via an extension of the tight-binding approach, providing a rigorous determination of the dissociation constants and degree of cooperativity. This general approach ...

In 2007, only 5,000 bbl/d of crude and 71,000 bbl/d of petroleum products, including fuel ethanol, moved on tankers and barges from the Midwest to the Gulf Coast. The growth in waterborne movements began in 2010 and was driven by increases in product movements because Midwest refineries with access to discounted crude oil increased the volume of crude oil processed; however, with limited product pipeline capacity from PADD 2 to PADD 3, those refineries turned to alternative modes of transportation to move their products. The growth in 2011 and 2012 waterborne shipments was driven by crude oil movements as production of crude oil in PADD 2 outpaced pipeline capacity growth and producers looked for alternative ways to move growing crude oil volumes to refining centers on the U.S. Gulf Coast ...

DESIGN AND EVALUATION OF EXPERIMENTS WITH LABYRINTHINE STATORECEPTORS.
The report establishes a theoretical framework and computational procedures which lead to an experimental strategy for distinguishing between two alternative modes of operation of the vestibular statoreceptors: the question is whether individual kinocilia in the maculae sacculi and utriculi are innervated by single vestibular afferent fibers; or else, whether convergence of neural discharges originating from several kinocilia with different orientation of functional polarization occurs in vestibular afferent fibers. If the former condition prevails, it is possible to calculate the vector of maximal sensitivity of each kinocilium from the polar plot of nerve discharge rates, obtained at suitable head positions in the gravity field. The principle of the procedure consists in the matching of experimental data with a computer simulated model of sacculus and utriculus. (Author)(*MEDICAL EQUIPMENT

Development of Multi-Class, Multi-Criteria Bicycle Traffic Assignment Models and Solution AlgorithmsDevelopment of Multi-Class, Multi-Criteria Bicycle Traffic Assignment Models and Solution Algorithms
Cycling is gaining popularity both as a mode of travel in urban communities and as an alternative mode to private motorized vehicles due to its wide range of benefits (health, environmental, and economical). However, this change in modal share is not reflected in current transportation planning and travel demand forecasting modeling processes. The existing practices to model bicycle trips in a network are not sophisticated enough to describe the full cyclist experience in route decision-making. The purpose of this paper is to develop a multi-class and multi-criteria bicycle traffic assignment model that not only accounts for multiple user classes by acknowledging that there are different types of cyclists with varying levels of biking experience, but also for relevant factors that may affect each user classes behavior in route choice decisions. The multi-class, multi-criteria bicycle traffic assignment model is developed in a two-stage process. The first stage examines key criteria to generate ...

Baricitinib - Insulin receptor signaling in the development of neuronal structure
The sort VI secretion system (T6SS) is a bacterial nanomachine for the transport of effector molecules into prokaryotic and eukaryotic cells. the existence of distinct T6SS classes. An accessory T6SS component, TagJ/HsiE, exists predominantly in one of the classes. Using bacterial two-hybrid approaches, we showed that the homolog HsiE1 interacts strongly with ClpV1. We then resolved the crystal structure of HsiE1 in complex with the N terminus of HsiB1, a TssB homolog and component of the contractile sheath. Phylogenetic analysis confirmed that these differences distinguish T6SS classes that resulted from a functional co-evolution between TssB, TssC, TagJ/HsiE, and ClpV. The interaction of TagJ/HsiE with the sheath as well as with ClpV suggests an alternative mode of disassembly in which HsiE recruits the ATPase to the sheath. mutant has a reduced T6SS-dependent killing activity toward VipA/VipB sheath (TssB/TssC homologs) (20, 21, 27) is dependent on a direct interaction between ClpV and ...

The Shoulder | Innova RecordingsThe Shoulder | Innova Recordings
We should begin with a word about Dan Hurlins text for The Shoulder, simply because that text is based on an extraordinary real-life story, the kind that tugs right on the heartstrings even as it charms the very pants from our loins. In 1994, shortly after being informed that failing eyesight prevented him from renewing his drivers license, a 74 year-old Iowa farmer, Alvin Straight, learned that his brother in Wisconsin had suffered a stroke. Unable to find an alternative mode of conveyance, due to the remoteness of their mutual locations, he made the 250-mile journey in 41 days, on a riding mower pulling a 10-foot trailer filled with camping supplies at an average speed at 5 miles per hour. You may remember it from the David Lynch version. Dan Moses Schreiers music for this inspired theatrical song-cycle treats Hurlins text exactly as it warrants, avoiding faux folksiness and gratuitous rigor alike in lieu of passion and charm, administered carefully as sacred herbs in a lambent panoply of ...

SÜDPACK: a great example of biotech as a cross-sectoral technology - Healthcare industrySÜDPACK: a great example of biotech as a cross-sectoral technology - Healthcare industry
In principle, the manufacturing process of films for use in biopharmaceutical applications is comparable to that of films for use in food packaging, says Schnellenbach. Pharmaceutical suppliers also have to adhere to precisely defined controlled production processes that are subject to defined change control. This also applies to the formulation of the granules from which the films are extruded at the company site in Ochsenhausen. The supply chain and secure supply of identical granules, documentation, marketing authorisation procedure and the accompanying measurements throughout the controlled production processes have to meet pharmaceutical industry standards.. Safety is the key to biopharmaceutical development and production. So-called extractables and leachables that can migrate from the polymer material into the active ingredients are considered the greatest of all potential risks. Extractables are compounds that can migrate from polymers over a prolonged period of time, at high ...

Thermal and kinetic characteristics in non-isothermal conditions of some aromatic copolyethers containing an octomethylenic...
The paper presents a study of the thermal properties of some aromatic polyethers obtained by phase trasfer catalysis technique. The polymes were synthesized starting from 1,8-dichloro-octane and various bisphenols: 4,4′-dihydroxyazobenzene, 4,4′-dihydroxydiphenyl, bisphenol A and 2,7-dihydroxynaphthalene. Molecular simulations were performed in order to obtain supplementary information concerning the chain conformation and inter-chain interactions. The presence of azobenzenic moieties induces high phase transition values, situated near the thermal stability limit. Therefore, the thermogravimetrical study of these polymers is very important for establishing the temperature limits for DSC and optical microscopy studies. All the polymers present a good thermal stability situated above the isotropization values. In these circumstances no special precautions are necessary for the characterization methods of the liquid crystalline behavior. The kinetic characteristics suggest a similar degradation ...

The factors of a healthy barn climate for pigs - Swineweb.com - Complete Swine News, Markets, Commentary, and Technical InfoThe factors of a healthy barn climate for pigs - Swineweb.com - Complete Swine News, Markets, Commentary, and Technical Info
Climate control in the barn for the most part consists of controlling the temperature. The difficulty in this case is the presence of different types of pigs. Per species (sows, piglets, meat pigs) the optimal temperature can be different and has to be adapted to. In the table below, we highlight estimates of desired temperatures for different species of pigs.. When it gets too cold, ventilation should be minimal to reduce heat disposal. Additional heating may be required to keep the pigs within their comfort zone. The comfort zone is defined here as the temperature limits within which little energy is required to maintain a steady body temperature. When it gets too warm, one should ventilate as much as possible to dispose of heat and create a draft.. ...

Bioneer Pacific - RocketScript™ Reverse TranscriptaseBioneer Pacific - RocketScript™ Reverse Transcriptase
Thermostable Activity: Native M-MLV reverse transcriptase has low thermostable activity, therefore restricting reverse transcription reactions to relatively low temperatures (42°C). This attribute prevents RNA molecules containing many stems and loops (complex secondary structures) from being efficiently transcribed. To resolve this shortcoming, Bioneer has utilized synthetic biotechnology to develop a RTase that is active even at high temperatures of 60°C and above. By removing the traditional reaction temperature limit of 42°C, you are now able to choose your reaction temperature from 42°C -70°C and optimize your cDNA synthesis experiments ...

Is solid helium a quantum crystal? - Fakultät für Physik - LMU München
It had been proposed that superfluidity could coexist with crystalline order in solid helium, thanks its quantum properties. If true, solid helium would have been be the first supersolid. For some years, one thought that this paradoxical coexistence of order in real and momentum space - named supersolidity - had been observed by several groups in the world. But nowadays, we understand that supersolidity does not exist in these crystals, but instead the mobility of their dislocations is so high in the low temperature limit and if all impurities are suppressed, that it does not resist to shear in some directions. The discovery of this giant plasticity in helium crystals is not less interesting than supersolidity. Its careful analysis has led to fundamental progress in the knowledge of dislocation networks and dynamics, which are basic phenomena at the origin of the plasticity of materials. Now a question remains: in the end, what is really quantum in these crystals? I will try to give some ...

A study of the properties of short glass fibre reinforced thermoplastic composites based on poly(ethylene terephthalate), poly(butylene terephthalate) and polyamide-6,6 in an aggressive environment is reported. The influence of the fibre/matrix interface on the composite behaviour in a moist environment is especially studied. Competitive phenomena may explain differences observed according to the nature of the fibre surface treatment. Among them these characteristics may be an intrinsic fragility of some chemical interfacial bonds, the hydrophilicity of some chemical groups, the presence of long macromolecular chains neighbouring the interface or of a transcrystalline interfacial area.

Comments: 78 Pages.. Nylon comprises a family of man-made substances that were first manufactured in 1935. Nylonases are biological enzymes that can break down nylon oligomers. Although the most prominent nylonases are within the family of enzymes classified as 6-aminohexanoate hydrolases, some enzymes not formally classified as 6-aminohexanoate hydrolases also have the ability to breakdown nylons, and so can also be classified as nylonases. Organisms that encode a nylonase enzyme do not necessarily have the ability to actually survive on a nylon substrate as their sole carbon source. Among the first documented organisms that did have this ability was the soil bacterium Arthrobacter KI72. It has long been thought that nylonase genes and proteins were essentially absent from the biosphere prior to 1935. This belief led to the widespread assumption that any nylonase gene observed in the present must have emerged since 1935. Several authors developed hypothetical models of how a specific nylonase ...

Engine Bearings 101 | Constructed, Crushed, & Clearanced for Max PerformanceEngine Bearings 101 | Constructed, Crushed, & Clearanced for Max Performance
Main and rod bearings feature similar constructions. These engine bearings are generally produced by either a casting process or by being sintered from powdered metal. The consensus among engine builders is that cast bearings are superior since the bearing layer (first layer) is completely continuous. The majority of high-performance bearings will use a steel back, a cast layer of a lead-bronze/copper-lead alloy (excellent for heat transfer), a nickel layer (barrier layer) and finally a softer lead-tin-copper overlay (slide layer). The barrier layer and slide layers are plated to the bearing layer in the multi-stage operation. In some cases, a special bearing-surface coating or WPC metal treatment is also applied to the bearing. The coatings improve the scuff-resistance of the bearings (during cold-starts with minimal oil pressure). The WPC metal treatment peens the surface of the bearing on a microscopic level while embedding it with solid lubricants such as Tin (Sn) and Molybdenum Disulfide (MoS2).
