Various explants (stem, leaf, and root) of Citrus assamensis were cultured on MS media supplemented with various combinations and concentrations (0.5-2.0 mg L(-1)) of NAA and BAP. Optimum shoot and root regeneration were obtained from stem cultures supplemented with 1.5 mg L(-1) NAA and 2.0 mg L(-1) BAP, respectively. Explant type affects the success of tissue culture of this species, whereby s...

A novel bacterium was isolated from a traditional fermented food, kimchi. The morphology, physiology, biochemical properties and 16S rRNA gene sequence of strain L133(T) were studied. Strain L133(T) was Gram-reaction-positive, catalase-negative and homofermentative, with rod-shaped cells that formed cream colonies. Cells grew in the presence of 0-5 % (w/v) NaCl (optimum, 1-2 %), at pH 5.0-9.0 (...

In recent years, use of biodegradable polymers based nanoparticles has received high interest in the development of vaccines delivery vehicles. The aim of study was to prepare chitosan nanoparticles (CS NPs) for loading Echis carinatus (EC) venom and evaluate their potential as an adjuvant and antigen delivery system on a pilot scale. CS NPs were prepared using ionic gelation method, and their ...

This study presents the synthesis of polyvinyl acetate (PVAc) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (PVA) using alkaline alcoholysis. The influence of the molar ratio of hydrolysis catalyst (NaOH) to PVAc and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the PVA were investigated using response su...

Methoxy poly(ethylene glycol) (mPEG) with molecular mass of 5 kDa activated with succinimidyl carbonate and cyanuric chloride, separately was covalently attached to human red blood cells (RBCs). Inhibition of agglutination by blood-type specific antisera (anti-D) was employed to evaluate the effect of the polymer coating. The remaining single cells after incubation with anti-D sera were cou...

Abstract In this work, the surrogate model of collapse load in terms structural morphology is established based on radial basis function (RBF) network, and form-finding optimization fabricated single-layer grid shell aiming at improvement collapse-resistance capacity realized. To improve accuracy optimal solution, density used to determine sparse region design domain add new sample points regio...

In this study, the surface morphology of net-patterned fluorine-doped tin oxide (FTO) films was optimized with mesh sizes (60 mesh, 40 and 24 mesh) using one-pot horizontal ultrasonic spray pyrolysis deposition (HUSPD) process. The 40M-FTO sample exhibited electrical optical properties due to improved crystallinity FTO. electrochromic (EC) electrodes fabricated showed superior EC performance, i...

Abstract In this paper, we study the influence of two key factors, temperature, and humidity, on gas sensors based titanium dioxide nanowires synthesized at 4 different temperatures with morphology. The samples’ structure are investigated using SEM, XRD FTIR analysis. effects humidity temperature studied by measuring resistance response when exposed to ethanol. At room observed a 15% sensitivit...

An empirical study is performed on the local-optimum space of graph bipartitioning. We examine some statistical features of the fitness landscape. They include the cost-distance correlations and the properties around the central area of local optima. The study revealed some new notable results about the properties of the fitness landscape; e.g., the central area yielded fairly good quality in t...
