Indentation is a primary tool in the investigation of the mechanical properties of very soft tissue such as the brain. However, the usual material characterization protocols are not applicable because the resulting deformation is inhomogeneous, with even the identification of the amount of strain ambiguous and uncertain. Focusing on spherical indentation only, a standard is needed to quantify t...

Two porcine rotavirus strains (CN86 and CC86) isolated during an epidemiological survey of diarrhoea in swine in Argentina were studied because of several unique characteristics. Both these strains were isolated and cloned from the same faecal sample and the electrophoretic migration of 10 of their 11 genomic dsRNA genomic segments in polyacrylamide gels was identical, but strain CC86 had a sup...

In experimental rabbit meningitis, gemifloxacin penetrated inflamed meninges well (22 to 33%) and produced excellent bactericidal activity (change in log(10) [Deltalog(10)] CFU/ml/h, -0.68 +/- 0.30 [mean and standard deviation]), even superior to that of the standard regimen of ceftriaxone plus vancomycin (-0.49 +/- 0.09 deltalog(10) CFU/ml/h), in the treatment of meningitis due to a penicillin...

The in vitro antimicrobial activity of different fractions obtained from rhizome of Curcuma longa was investigated against standard strain and clinical isolates of Staphylococcus aureus. The clinical isolates were found more sensitive for different fractions, than the standard strain of S. aureus. Scanning electron microscopic observations revealed that test pathogen treated with C. longa extra...

In the present study, a series of new substituted oxazolone derivatives (4a-4h) were synthesized by the Erlenmeyer condensation of phthaloylglycylglycine with different aldehydes in the presence of anhydrous sodium acetate and acetic anhydride. The structure of newly-synthesized compounds were evaluated by elemental analyses and spectral ( UV-Visible, IR, NMR, Mass) studies. All the synthe...

background nursing teachers have difficulties fulfilling multiple roles expectations and balancing the various dimensions of their roles that may lead to role strain. in order to lack of culturally and academically proper scale in iran to measure role strain in nursing teachers, localizing a foreign scale in this field is necessary. objectives the objective of this study was psychometric evalua...

Three kinds of recycled aggregate concretes (RACs), with six different replacement rates at four ages, are subjected to the standard cube axial compression test study mechanical properties. Failure modes, compressive strength, stress-strain curves, peak strain, and elastic modulus RACs systematically analysed. In addition, three equations proposed for describe relationship between strength rate...

Nucleic acid amplification technique-based assays are a primary method for the detection of acute hepatitis E virus (HEV) infection, but assay sensitivity can vary widely. To improve interlaboratory results for the detection and quantification of HEV RNA, a candidate World Health Organization (WHO) International Standard (IS) strain was evaluated in a collaborative study involving 23 laboratori...

Strains. Wild type C. elegans (strain N2) were obtained from the Caenorhabditis Genetics Center (University of Minnesota), and ftn-2(ok404) and the ferritin null ftn-2(ok404); ftn-1(ok3625) (strain GMC005) have been previously described1. All strains were cultured at 20 °C on standard nematode growth media (NGM) with E. coli (strain OP50)2. Populations were developmentally synchronized via a 3 ...

The development of slip lines, due to strain localization, is a common cause for failure of soil in many circumstances investigated in geotechnical engineering. Through the use of numerical methods -like finite elementsmany practitioners are able to take into account complex geometrical and physical conditions in their analyses. However, when dealing with shear bands, standard finite elements d...
