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)

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 ...

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 ...

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. ...

Results - In 16°C half the swimmers did not complete a two-hour swim in 16°C; four became (or were predicted to become) hypothermic within two hours. In 18 °C, three quarters completed the swim; three became (or were predicted to become) hypothermic. In 20 °C, one swimmer was predicted to become hypothermic in under two hours. The mean linear rate of fall of Tre was greater in 16°C (-1.57°C.hr-1) than 18°C (-1.07°C.hr-1) (p = 0.03). There was no change in swimming performance during the swims or between conditions. Most of the cooling rate could be explained by metabolic heat production and morphology for both 16 °C (R2 = 0.94, p ˂0.01) and 18 °C (R2 = 0.82, p ˂ 0.01) conditions. No relationship was observed between Tre and perception of thermal sensation (r = 0.25, p = 0.13) and there was a weak correlation between Tre and thermal comfort (r = 0.32, p = 0.04 ...
Kosterlitz and Thouless (and independently Berezinskii) were looking at the problem of phase transitions in two dimensions of a certain type. As an example, imagine a huge 2d array of compass needles, each free to rotate in the plane, but interacting with their neighbors, so that neighbors tend to want to point the same direction. In the low temperature limit, the whole array will be ordered (pointing all the same way). In the very high temperature limit, when thermal energy is big compared to the interaction between needles, the whole array will be disordered, with needles at any moment randomly oriented. The question is, as temperature is increased, how does the system get from ordered to disordered? Is it just a gradual thing, or does it happen suddenly in a particular way? It turns out that the right way to think about this problem is in terms of vorticity, a concept that comes up in fluid mechanics as well (see this wiki page with mesmerizing animations). Its energetically expensive to ...

TY - JOUR. T1 - Comparative study of the effects of high hydrostatic pressure on physicochemical, thermal, and structural properties of maize, potato, and sweet potato starches. AU - Rahman, Md Hafizur. AU - Mu, Tai Hua. AU - Zhang, Miao. AU - Ma, Meng Mei. AU - Sun, Hong Nan. PY - 2020. Y1 - 2020. N2 - Effects of high hydrostatic pressure (HHP, 100, 300, and 500 MPa for 15 and 30 min at 25°C) on physicochemical, thermal, and structural properties of maize, potato, and sweet potato starches (20%, w/w) were investigated. Amylose and damaged starch contents of all three starches were increased, but their solubility and swelling power were decreased after HHP treatment. Thermal properties of maize starch were significantly different from those of potato and sweet potato starches. Maize starch treated at 500 MPa was completely gelatinized with larger particle sizes and exhibited lower pasting properties than potato and sweet potato starches. The crystalline pattern of maize and potato starches was ...

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 ...

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 ...
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 ...
Electrospinning is a versatile method to fabricate nanofibers of a range of polymeric and composite materials suitable as scaffolds for tissue engineering applications. In this study, we report the fabrication and characterization of polyaniline-carbon nanotube/poly(N-isopropyl acrylamide-co-methacrylic acid) (PANI-CNT/PNIPAm-co-MAA) composite nanofibers and PNIPAm-co-MAA nanofibers suitable as a three-dimensional (3D) conducting smart tissue scaffold using electrospinning. The chemical structure of the resulting nanofibers was characterized with FUR and H-1 NMR spectroscopy. The surface morphology and average diameter of the nanofibers were observed by SEM. Cellular response of the nanofibers was studied with mice L929 fibroblasts. Cell viability was checked on 7th day of cell culture by double staining the cells with calcein-AM and PI dye. PANI-CNT/PNIPAm-co-MAA composite nanofibers were shown the highest cell growth and cell viability as compared to PNIPAm-co-MAA nanofibers. Cell viability in ...

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. The frequency of micronucleated normochromatic erythrocytes in the bone marrow and peripheral blood of mice from the 13-week study was also determined.. In the 2-week study, groups of five male and five female mice were given ...
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 ...
Phenol ranked 38th in production among U.S. chemicals in 1978 with annual production of 2.38 billion pounds. Approximately 90% of the phenol produced is used in the manufacture of phenolic (phenol formaldehyde) resins, caprolactam, bisphenol A, alkyl phenol, and adipic acid. The remainder of the phenol is used to produce an assortment of end products, including salicylic acid, phenacetin, dyes, metal cleaners, disinfectants, antiseptics, photographic chemicals, wood preservatives (pentachlorophenol), paints, paint and varnish removers, and agricultural chemicals (2,4-D and parathion).. A bioassay of phenol to test for possible carcinogenicity was conducted by providing this substance in drinking water to F344 rats and B6C3F1 mice. Groups of 50 rats and 50 mice of each sex were given drinking water containing 2,500 or 5,000 ppm phenol for 103 weeks. As matched controls, groups of 50 rats and 50 mice of each sex received tap water.. A dose-related depression in mean body weight gain occurred in ...

Dry lubricants can be classified into solid lubricants in powder form, ceraceous sliding films and in bonded coatings containing solids. Bonded coatings are solid lubricants (usually MoS2, graphite or PTFE) that are incorporated into an organic or inorganic binder. In order to allow distribution of the bonded coating, a solvent which evaporates during the hardening or drying time is added. After thorough preparation of the surface, coating is carried out by means of immersion, spraying or painting. ...
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 ...
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
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 ...
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 ...
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 ...
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.. ...
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 ...
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 ...

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).

Although many diseases (such as heart failure) may have a worse prognosis than most cases of cancer, cancer is the subject of widespread fear and taboos. The euphemism of "a long illness" to describe cancers leading to death is still commonly used in obituaries, rather than naming the disease explicitly, reflecting an apparent stigma.[190] In Nigeria, one local name for cancer translates into English as "the disease that cannot be cured".[191] This deep belief that cancer is necessarily a difficult and usually deadly disease is reflected in the systems chosen by society to compile cancer statistics: the most common form of cancer-non-melanoma skin cancers, accounting for about one-third of cancer cases worldwide, but very few deaths[192][193]-are excluded from cancer statistics specifically because they are easily treated and almost always cured, often in a single, short, outpatient procedure.[194] Western conceptions of patients' rights for people with cancer include a duty to fully disclose ...
Before DDT, malaria was successfully eliminated or curtailed in several tropical areas by removing or poisoning mosquito breeding grounds and larva habitats, for example by eliminating standing water.

It is difficult, if not impossible, to predict when and where the breeding sites will form, and to find and treat them before the adults emerge."[138] The relative effectiveness of IRS versus other malaria control techniques (e.g. bednets or prompt access to anti-malarial drugs) varies and is dependent on local conditions.[34] A WHO study released in January 2008 found that mass distribution of insecticide-treated mosquito nets and artemisinin-based drugs cut malaria deaths in half in malaria-burdened Rwanda ...
DNA damage is considered to be the primary underlying cause of malignant neoplasms known as cancers.[16][17] Its central role in progression to cancer is illustrated in the figure in this section, in the box near the top. (The central features of DNA damage, epigenetic alterations and deficient DNA repair in progression to cancer are shown in red.) DNA damage is very common. Naturally occurring DNA damages (mostly due to cellular metabolism and the properties of DNA in water at body temperatures) occur at a rate of more than 60,000 new damages, on average, per human cell, per day[16] [also see article DNA damage (naturally occurring) ]. Additional DNA damages can arise from exposure to exogenous agents. Tobacco smoke causes increased exogenous DNA damage, and these DNA damages are the likely cause of lung cancer due to smoking.[18] UV light from solar radiation causes DNA damage that is important in melanoma.[19] Helicobacter pylori infection produces high levels of reactive oxygen species that ...
