The aim of this study was to examine the hypothesis that plants with higher ploidy levels are selected by environments under more extremely stressful conditions than the same (or closely related) species from less rigorous terrestrial or epiphytic habitats. Therefore, we analyzed the chromosome numbers of 26 species belonging to 21 genera and 13 families of angiosperms that were collected on 4 ...

soil salinity affects ions concentrationss of plant tissues and this may alter the merits quality of medicinal plants. experiments were conducted during 2003 at the the isfahan university of technology campus, isfahan, iran, to assess the effects of five soil salinity levels (3.2, 3.6, 4.5, 5.4 and 7.5 ds m-1) on na, k, and ca contents of borage and echium. each plant species was studied in a s...

background and objective : the prevalence of community acquired methicillin resistant staphylococcus aureus (ca-mrsa) is increasing around the world. it involves healthy people and causes a variety of diseases. material and methods : this cross sectional study was conducted from september 2010 - june 2011 on children less than 14 years of ahvaz, southwest iran. the participants were selected wi...

background: the number of interventional cardiology (ic) procedures has increased rapidly. coronary angiography (ca) and percutaneous transluminal coronary angioplasty (ptca) are now widely performed as a matter of routine, and they are considered safe procedures for experienced cardiologists. however, it is also known that these procedures are associated with high radiation doses due to long f...

This report documents our efforts to develop a Generation Challenges 2011 surface realization system by converting the shared task deep inputs to ones compatible with OpenCCG. Although difficulties in conversion led us to employ machine learning for relation mapping and to introduce several robustness measures into OpenCCG’s grammar-based chart realizer, the percentage of grammatically complete...

An acid invertase was isolated and partially purified from mature sugarcane (var HSF 240) stem juice by a combination of Ammonium sulphate, DEAE-cellulose and gel filtration. The purified acid invertase had a specific activity of 17.05 Umg1. Invertase was characterized for various parameters. The pH and temperature optima of the enzyme were 3.0 and 45°C respectively. The Km value and energy of ...

Compression mode giant resonances have been measured in many nuclei from C to Pb with inelastic scattering of 240 MeV particles at small angles. Isoscalar monopole distributions have been extracted for 17 nuclei and isoscalar dipole distributions extracted for 11 nuclei. The E0 strength distributions in Zr, Sn, Sm and Pb have been measured precisely and in Sn, Sm and Pb were found to be concent...
