it has been well documented that preeclampsia (pe) has a common etiological background, but little is known about its linkage at the molecular level.non- coding rnas are critical posttranscriptional regulators ofgene expression. this study was performed to determine whether peis associated with alterations in placental non-codingrnas expression. microrna(mir)-155-5p and long non-coding rna (ln...
background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...
to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...
در این رساله، وجود و چندگانگی جواب های مثبت دسته ای از معادلات و دستگاه معادلات دیفرانسیل با مشتقات جزئی غیرخطی با شرط های مرزی همگن دیریکله را بر اساس روش جواب های پایینی-بالایی در دو مفهوم کلاسیک و ضعیف مورد بحث قرار می دهیم. فرض کنید $omega$ دامنه ای کراندار در $mathbb{r}^n$ با مرز هموار $partial omega$ است. ابتدا، وجود جواب های مثبت مسائل نیمه مثبت گون نامتناهی [ -delta u=-a ...

to mutate the ice nucleation active (ina) gene in erwinia herbicola strains, tn-5 transposon carried by psup2021 plasmid was used. this plasmid was transferred to the bacterial cells by electroporation. electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. polymerase chain reaction was used for determination of presence or loss of ina gene, using a...
in order to study the effects of four concentrations (check, 5, 10 and 15%) of hull extracts on growth of 10 iranian rice cultivars, two experiments were conducted in completely randomized block design with factorial arrangement and three replications at two sites, laboratory and greenhouse. laboratory study showed that same rice hull extracts had stimulat effects and the others had inhibitory ...
the aim of this study was to investigate the effect of a change in the sequence of concurrent endurance and strength training on aerobic power and body composition of active men. 30 men (mean age 25.8 ± 3.50 years) with endurance and strength training history were divided into these groups: endurance training before strength training (es, n=10), strength training before endurance training (se, ...
in order to assess the impact of different sowing dates on yield and yield components of wheat genotypeswith different growth habits, a two years study (2007-2009) using a split plot in randomized completeblock design with three replications was conducted in kabootarabad agricultural research station ofisfahan. three sowing dates of 12 oct., 1 nov., and 21 nov. were main plots and 15 genotypes ...
waterlogging is one of the problems of cotton-growing in rainy regions which affects adversely plant growth in the early stages. so that rainfall causes waterlogging in early to mid spring in the fields without proper drainage. also, rainfall declines soil and environment temperatures. to investigate the effects of waterlogging period duration and temperature on vegetative properties and glycol...
