Transient analysis of layered composite plates accounting for transverse shear strains and von Karman strains
The increasing use of laminated composites in moving structures such as aircraft has led to a need for an efficient and accurate procedure for performing transient bending analysis of laminated composite plates. Classical theory is inadequate because it neglects transverse shear deformation, …

Identification of strains of Rhizobium leguminosarum
… natural variation in the ability of individual strains to tolerate such stress. This could inform the development of better commercial inoculants and enable them to persist better in dry soils. Numerous researchers have investigated the nodulation ability and nitrogen fixation efficacy of R. …

Peripheral Taste System in Inbred Mouse Strains
Taster and non-taster mice strains have been used extensively in animal taste research. Inbred mouse strains C57 and FVB have been proposed to be tasters, where as strains 129 and Balb/C are classified as non-tasters. Therefore, evaluating the peripheral taste system in these mice is of great …

Glycerol from novel strains of halophytic microalgae
… research explored glycerol production in new strains of halotolerant microalgae Dunaliella (T35, T36 and T37) and Asteromonas (T33a, T33b and T33c) obtained from Namibia. The aim was to: (a) Determine the optimum conditions of pH value, temperature and salinity on the specific growth rate and …

Work stressors, strains and hospital unit performance
… in psychological, physiological, and behavioural strains, and subsequently, in suboptimal performance. This thesis includes two studies which investigate the stressor-to-strain-to-performance relationships in hospitals. The first study is a cross-sectional, multi-group investigation based on …

Soybean mosaic virus: strains, ultrastructure and movement
… (SHV), VA and OCM, were classified as G1 and G3 strains, respectively, according to a soybean differential cultivar system. G1/VA and G3/OCM differed in the symptom severity induced on soybean (Glycine max [L.]Merr.) plants and by the production by G3/OCM of cytoplasmic strands, containing virus …

Closure of fatigue cracks at high strains
… closure behavior of short cracks at high cyclic strains under completely reversed cycling. Testing procedures and methodology, and closure measurement techniques, are described in detail. The strain levels chosen for the study cover from predominantly elastic to grossly plastic strains. Crack …

Genome sequence of the hyperinvasive Campylobacter jejuni strains
… of hyperinvasiveness in a group of six C. jejuni strains which have been reported as hyperinvasive into human intestinal cell lines. Here, genomotyping of the hyperinvasive C. jejuni was performed by comparative genomic hybridization (CGH) against four low invasive C. jejuni strains. A group of 67 …

Physiological Characterization of Four Psychrophilic Marine Bacterial Strains
… characterized for taxonomic identification. All strains are Gram-negative obligate aerobes requiring seawater based medium. None of the four strains will grow at or above 22°C. All strains are orange-pigmented, encapsulated, and catalase positive. Strain 12-02 is C-shaped and motile. The …

Nitrate and nitrite growth inhibition of Desulfovibrio strains
Sulfate-reducing bacteria, common non-pathogenic soil bacteria, have the ability to limit the movement of toxic heavy metals from one environmental site to another by keeping those metals from dissolving in water. Limiting the movement of heavy metals into drinking water supplies is especially …

Biological Studies on Various Strains of Trypanosoma Avium
The purpose of this study was to further investigate avian trypanosomids, relative to the Magpie, Steller's Jay, and Sparrowhawk, and to initiate work for a newer aspect of trypanosome study; the effects of radiation upon trypanosome growth in vitro.
