Abstract The main traditional technique for commercial manufacturing of composite pipes is filament winding in which the winding angle and the discontinuity of the structure (caused by starting and ending points of the winding process) are two important matters of concern. In the present study, circular woven fabric w…
The effect of electron beam (EB) irradiation on the tensile, flexural and morphological properties of low-density polyethylene (LDPE)/ethylene-propylene diene elastomer (EPDM) blends had been studied in the absence and presence of crosslink promoters, such as trimethylolpropane triacrylate (TMPTA) and triallyl cyanura…
In the past decade, several higher-order crystal plasticity models have been developed to properly capture size effects, dislocation pile-up and patterning. Here we consider a formulation which accounts for the presence and behavior of both positive and negative dislocations in terms of densities. We derive an implici…
Abstract Based on a further study on knitting and jacquard principles, this paper presents a mathematical design model to make computer-aided design of warp-knitted jacquard spacer fabrics more efficient. The mathematical model with matrix method employs three essential elements of chain notation, threading and Jacqua…
ABSTRACT Cowhide, a natural biopolymer of collagen, forms raw material for leather, biomaterials, and food, among others. Thermal and mechanical analysis was done using dynamic mechanical analyzer. Effect of tanning and natural solar radiations on the storage modulus, tan δ, and thermal stability of pickled and tanned…
Jute is considered as one of the cheapest natural fibre after cotton in terms of its production and uses. Retting is the most important post-harvest operation to yield high quality jute fibre and is solely carried out by various types of retting microorganisms. The present study was undertaken to screen and characteri…
Abstract A series of xNi@Al2O3 catalysts with different Ni content was prepared by impregnation combustion method, the catalytic performance for CO methanation in a slurry‐bed reactor at low‐temperature was studied, and the structure of the catalysts was characterized by X‐ray diffraction, N2 adsorption–desorption, te…
Symmetry protected edge states in 2D topological insulators are interesting both from the fundamental point of view as well as from the point of view of potential applications in nanoelectronics as perfectly conducting 1D channels and functional elements of circuits. Here using a simple tight-binding model and the Lan…
The U32 family is a collection of over 2500 annotated peptidases in the MEROPS database with unknown catalytic mechanism. They mainly occur in bacteria and archaea, but a few representatives have also been identified in eukarya. Many of the U32 members have been linked to pathogenicity, such as proteins from Helicobac…
Abstract Silver antimony sulfoselenide thin films have been investigated for photovoltaic applications. In the present work, we report preparation of AgSb(SxSe1‐x)2 by a rapid thermal processing of pre‐annealed Sb2S3/Ag/Se/Ag/Se layered structures. Sb2S3thin films were deposited by chemical bath deposition and Ag by t…
Size-exclusion chromatography with light scattering detection experiments conducted on poly(acrylic acid) neutralized to different degrees or using hydroxides with different counterions suggest that the same counterion and degree of neutralization is observed at the detector, irrespective of salt concentration, degree…
A major challenge to emerging cell-based medicine including gene therapy is the host immune rejection of transplanted donor cells or engineered tissue. One way to address this problem is to use drugs to achieve immunosuppression. However, suppressing the patient’s immune system may put the patient at risk for many oth…
PURPOSE: The aim of this study was to evaluate of the effect of distilled water and saline ultrasonic nebulization on the inflammatory and oxidative stress responses and on the lower airway architecture. MATERIALS AND METHODS: Twenty-one male Fischer rats were distributed into 3 groups of 7 animals each: a control gro…
The disruption of protein hydroxylation is highly associated with several serious diseases and consequently the identification of protein hydroxylation sites has attracted significant attention recently. Here, we report the development of an improved method, called HydPred, to identify protein hydroxylation sites (hyd…
Abstract A novel type of aramid fibers coated with poly(ethylene glycol) methyl ether (PEGME)-modified multi-walled carbon nanotubes (MWCNTs) was designed using electrophoresis. Owing to the good interaction of MWCNT-PEGME with the matrix, the coated fibers were well dispersed in epoxy resin. Thin films of epoxy/arami…
Carbon fabric (CF)/phenolic laminates filled with pristine and chromic acid treated ultra high molecular weight polyethylene (UHMWPE) microparticles were fabricated. Their interfacial and tribological properties in water environment were comparatively investigated. The interlaminar shear strength (ILSS) of the laminat…
A series of five crystal structures of 1 : 1 halogen-bonded complexes were obtained from 4-[5-(4-alkoxyphenyl)-1,3,4-oxadiazole-2-yl]pyridine and 1,3,5-trifluorotriiodobenzene. Electronic structure calculations show that the N(oxadiazole)⋯I interaction in the new synthon is as strong as the classic N(pyridine)⋯I inter…
Candida antarctica lipase B (CalB) was used as a chemoselective catalyst for the synthesis of multifunctional oligoester resins based on an epoxy-functional ω-hydroxy-fatty acid (EFA) extracted from birch bark.
The villin headpiece helical subdomain (HP36) is one of the best known model systems for computational studies of fast-folding all-α miniproteins. HP21 is a peptide fragment-derived from HP36-comprising only the first and second helices of the full domain. Experimental studies showed that although HP21 is mostly unfol…
Wormlike micelles are typically formed by mixing cationic and anionic surfactants because of attractive interactions in oppositely charged head-groups. The structural transitions of wormlike micelles triggered by pH in ionic liquids composed of N-alkyl-N-methylpyrrolidinium bromide-based ILs (ionic liquids) and anthra…
