In order to study the genetic diversity of 75 Iranian rice genotypes (45 Iranian land race, 25 improved cultivars, and 5 exotic cultivars) with respect to their salinity tolerance at seedling stage and to determine tolerance indices, based on biomass, genotypic code and Na+/K+ ratio a factorial experiment in randomized complete block design with three replications was conducted under control an...
Effect of glycine betaine and salinity on photosynthetic pigments and ion concentration of safflower
The influence of exogenous application of glycine betaine (GlyBet) was examined on photosynthetic pigments and ions concentration of safflower under salinity stress conditions. The experiment was performed in a randomized complete block design arranged as a factorial with three replications. Salinity treatments (0, 50, 100, and 150 mM) were applied using sodium chloride (NaCl). GlyBet (0, 10, 3...
Particulate emissions from residential wood combustion in Europe revised estimates and an evaluation
Currently residential wood combustion (RWC) is increasing in Europe because of rising fossil fuel prices but also due to climate change mitigation policies. However, especially in small-scale applications, RWC may cause high emissions of particulate matter (PM). Recently we have developed a new high-resolution (7×7 km) anthropogenic carbonaceous aerosol emission inventory for Europe. The invent...
An experiment was conducted in Algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. Serum Ca, Mg and Na levels were significantly high at birth and decreases as the age advanced. The season had a significant effect on the decreased levels of Ca, Mg and K and inversely on the increased levels of N...
The objective of the present research was to investigate the effect of salinity stress on sodium, potassium and calcium concentrations, and Na+/K+ and Na+/Ca2+ ratios at seedling stage in an advanced back cross (BC2F6) rice population. The population was derived from crossing between Hashemi, an Iranian cultivar, and IR67418-110-32222 (IR-22) from IRRI. The ANOVA indicated that the effects of g...
BACKGROUND The aim of this study was to determine whether adding water-contrast in the rectum during transvaginal ultrasonography (RWC-TVS) improves the diagnosis of rectal infiltration in women with rectovaginal endometriosis. METHODS This prospective study included 90 women, with suspect rectovaginal endometriosis, who underwent operative laparoscopy. TVS and RWC-TVS were independently perf...
به منظور بررسی اثرات متقابل تنش های شوری و خشکی بر رشد دو رقم سورگوم (اسپیدفید و پگاه) یک آزمایش فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار در گلخانه گروه خاکشناسی دانشگاه زنجان انجام شد. در این آزمایش فاکتورهای شوری و خشکی هر کدام دارای چهار سطح و فاکتور رقم دارای دو سطح بود. اعمال تیمارهای شوری از طریق آبیاری گلدان های حاوی ارقام مختلف سورگوم با آب شور صورت پذیرفت. سطوح شوری آب آبیاری عبار...
Objectives. The aim of this study was to compare the musculoskeletal and physical strain on healthcare workers, by measuring range of motion (ROM), muscle activity, and heart rate (HR), during transfer of a simulated patient using either a robotic wheelchair (RWC) or a conventional wheelchair (CWC). Methods. The subjects were 10 females who had work experience in transferring patients and anoth...
Matricaria chamomilla is a medicinal plant that is widely cultivated in salt affected soils. This investigation was undertaken to study the effect of NaCl concentration on germination, and the physiological, biochemical and growth characteristics of chamomile. Seed germination and growth were studied at five NaCl concentration levels (0, 40, 80, 120 and 190 mM NaCl concentration). Increasing th...
macrobrachium rosenbergii lifecycle is unique so that the adults thrive in freshwater and larval development requires brackish water environments near to estuaries as close as possible to larval body isosmotic for minimum na/k-atpase activity and maximum atp storage. osmoregulation system at early larval stages is not formed and larval osmoregulation is mainly attributed to na/k-atpase activity...
