تغِیِیرات اقلِیمِی مِیتواند باعث تغِیِیر در آبدهِی متوسط سالانه و فصلِی، بزرگِی و فراوانِی سِیلابها و خشکسالِیها گردد. اِین عوامل بر روِی مدِیرِیت منابع آب کشاورزِی و اکوسِیستمهاِی آبِی تاثِیرگذار است. بدِین منظور حوضه آبخِیز کسِیلِیان در ناحِیه خزر مورد بررسِی قرار گرفت. سرِیهاِی زمانِی روزانه و ماهانه آبدهِی در دوره زمانِی 89-1334 مورد بررسِی قرار گرفتند. پس از بازسازِی سرِیهاِی زمانِی 8 شاخص آبدهِی شامل Q5, Q10, Q30...
This paper estimates a class of models which satisfy a monotonicity condition on the conditional quantile function of the response variable. This class includes as a special case the monotonic transformation model with the error term satisfying a conditional quantile restriction, thus allowing for very general forms of conditional heteroscedasticity. Furthermore, the monotonicity condition enab...
The mud crab, Scylla paramamosain, has abundant nutrients in the ovary, where numerous lipids accumulate during ovarian maturation. However, mechanism behind accumulation of ovary crab maturation is largely unknown. This study conducted a comparative transcriptome analysis ovaries crabs at various stages A total 63.69 Gb clean data was obtained, with Q30 93.34%, and 81,893 unigenes were identif...
هدف از نگارش این پایاننامه، بررسی، جمعآوری و معرفی نمادهای مذهبی و سمبلهای دینی و نقد آثار هنری هنرمندان معاصر ایران با مضامین مذهبی و به ویژه عاشورایی از منظر فرم، رنگ و شعار و همچنین بررسی هنر مذهبی ایران از دوران آلبویه تاکنون و معرفی هنرهای دینی شاخص آن دوران میباشد. محقق، با طبقهبندی پُسترهای عاشورایی براساس رنگهای غالب، یک جامعه آماری از جهت نمادها، رنگها، فرمها و در نهایت شعارهای به کار ر...
High-throughput amplicon sequencing that primarily targets the 16S ribosomal DNA (rDNA) (for bacteria and archaea) Internal Transcribed Spacer rDNA fungi) have facilitated microbial community discovery across diverse environments. A three-step PCR utilizes flexible primer choices to construct library for Illumina has been applied several studies in forest agricultural systems. The protocol, whi...
Wheat (Triticum aestivum L.) is one of the most important crops cultivated worldwide. Identifying the complete transcriptome of wheat grain could serve as foundation for further study of wheat seed development. However, the relatively large size and the polyploid complexity of the genome have been substantial barriers to molecular genetics and transcriptome analysis of wheat. Alternatively, RNA...
The H9N2 subtype low pathogenic avian influenza is one of the most prevalent avian diseases worldwide, and was first documented in 1996 in Korea. This disease caused serious economic loss in Korea's poultry industry. In order to develop an oil-based inactivated vaccine, a virus that had been isolated in 2001 (A/chicken/Korea/01310/2001) was selected based on its pathogenic, antigenic, and genet...
This article updates Kelly and Bruestle (2011) by illustrating how publication trends in different subject categories in economics evolved from 2007 to 2013. Using data from RePEc we show that the largest increase in the relative share was for articles published in JEL category Q (“Agricultural and Natural Resource Economics, Environmental and Ecological Economics”) over this period. Furthermor...
The journal of economic literature classification scheme is a standard scheme to classify economics paper. This paper exames the usage of the scheme in a large set of economics papers. I document what subjects are central to the work of economics.
