Body's iterative force-field computer program has been used to calculate strain energies in cyclooctanone (I). 348 MHZ 1H NMR spectra of (I) have been investigated over the temperature range of 25° to -160°C. Two conformation processes affect the 1H NMR spectrum of (I). Iterative force-field calculations on the conformations and conformational interconversion paths of ...

In this study, the effects of nitrogen addition on the production of ultrafine/nano grained AISI 201L stainless steel by advanced thermo-mechanical process were investigated. Cast samples were first homogenized at 1200 °C for 4 h, hot-rolled at 1100 °C and finally, solution-annealed at 1150 °C for 2.5 h. Unidirectional and cross multipass cold rolling at 25 °C was carried out to 90% reduction i...

Foot-and-mouth disease virus (FMDV) serotypes O, A and Asia1 are responsible for a significant number of disease outbreaks in Iraq. The current study can be considered as the first molecular characterization of serotype Asia1 in Iraq. The present investigation reports the detection of serotype FMDV Asia1 from local farms in Sulaimani districts in 2012 and 2014 outbreaks. Phylogenetic analysis o...

in order to evaluate nitrogen fixation ability and nutrients uptake in three cultivars of common bean (phaseolus vulgaris l.) inoculating with some types of inoculants containing different strains of rhizobium leguminosarum; bv. phaseoli an experimental design was conducted in khoramdarah region in 2006 and 2007. in this investigation three types of biological fertilizers including rb117, rb123...

When an impurity is doped in a solid, it inevitably induces a local stress, tending to expand or contract the lattice. Consequently, strain can be applied to change the solubility of impurity in a solid. Generally, the solubility responds to strain "monotonically," increasing (decreasing) with the tensile (compressive) strain if the impurity induces a compressive stress or vice versa. Using fir...

The different steps of phagocytosis, attachment, ingestion and intracellular killing of cells of Helicobacter pylori strain 17874 (expressing sialic acid-specific haemagglutinin) and cells of H. pylori strain 17875 (expressing non-sialic acid-specific haemagglutinin) have been studied. More cells of sialopositive H. pylori strain 17874 have been found attached to human peripheral blood mononucl...
