Let G be a group, let T be an (oriented) G-tree with finite edge stabilizers, and let V T denote the vertex set of T . We show that, for each G-retract V ′ of the G-set V T , there exists a G-tree whose edge stabilizers are finite and whose vertex set is V ′. This fact leads to various new consequences of the almost stability theorem. We also give an example of a group G, a G-tree T and a G-ret...
The polymers used in plastics are generally harmless. However, they are rarely used in pure form. In almost all commercial plastics, they are "compounded" with monomeric ingredients to improve their processing and end-use performance. In order of total volume used, these monomeric additives may be classified as follows: reinforcing fibers, fillers, and coupling agents; plasticizers; colorants; ...
Method for production and regeneration of Acetobacter pasterianus protoplasts is described. The protoplasts were obtained by treatment of cells with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplast formation was obtained in protoplast buffer with NaCl (0.5M) as ...
Huang Shu and Tongwen Chen Dept. of Electrical and Computer Engineering University of Calgary Calgary, Alberta, Canada T2N 1N4 [email protected] [email protected] Abstract For a single-machine, in nite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H1 optimization. The digital stabilizers designed have low ...
Model tests were performed with different temperatures and soil stabilizers to investigate the effect of horizontal frost heave force on open tunnels in seasonal frozen regions. Experimental results show that dissipation accelerated increase temperature, data indicate compared without stabilizers, decreased by 10% 15% lignin fiber Huaxia No. 1 stabilizer. It can be concluded inhibitory stabiliz...
OBJECTIVE This study surveyed the use of adjunctive mood stabilizers (MS) and benzodiazepines (BZD) in older Asian schizophrenia patients and examined their demographic and clinical correlates. METHOD Information on hospitalized schizophrenia patients aged 55 years or more were extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study. A total of 1,4...
depression is a serious disorder in today’s society, with the estimates of lifetime prevalence being as high as 21% of the general population in some developed countries. as defined by the american psychiatric association, depression is a heterogeneous disorder often manifested with symptoms at the psychological, behavioral, and physiological levels. such patients are often reluctant to take sy...
We construct the first sharply 3-transitive groups not arising from a near field, i.e. point stabilizers have no nontrivial abelian normal subgroup.
Sodium salt of N-acetyl-DL-tryptophan (AT) and octanoic acid (caprylic acid CA) individually and in combination were studied as thermal stabilizer with different concentrations in heat treatment of human albumin solution. HPLC protein profiles before pasteurization of albumin showed less than 1% polymer. In free stabilizer albumin solution during pasteurization visible clot was formed. But by u...
In this research, Zn0.97Cu0.03O nanoparticles are prepared by sol-gel method using various stabilizers (Mono, Di, and Tri-ethanolamine). The effect of stabilizers on the structural, morphological and optical properties of the nanoparticles were investigated. Study of X-ray diffraction pattern shows the hexagonal wurtzite structure of samples. The crystallite size, strain, stress, and deformatio...
