Thermochemical conversion of non-edible biomass offers an efficient and economically process to provide valuable fuels and prepare chemicals derived from biomass in the context of developing countries. Pyrolysis has advantages over other thermochemical conversion techniques because it can convert biomass directly into solid, liquid and gaseous products by thermal decomposition of biomass in the...

a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...

Characterization of polycrystalline silicon particles produced in a fluidized bed reactor via CVD from monosilane was carried out It was observed that part of the hydrogen from monosilane remained in the particles. Most of hydrogen was bonded to silicon and temperatures as high as 1300 K were required to dehydrogenate the silicon particles. Particles were contaminated with metal elements which ...

MicroRNAs (miRNAs) are small (∼ 22 nucleotides) RNA molecules that base-pair with mRNA primarily at the 3′ untranslated region (UTR) to cause mRNA degradation or translational repression (Bartel [2009]). The expression levels of miRNA and mRNA are usually measured by microarray or RNA-seq. Paried expression profiling of both miRNA and mRNA enables identifying miRNA-mRNA interactions within an i...

تقاضا برای اُلفین های (آلکِن های) سبک مانند پروپن، بوتن و ایزوبوتن و محصولاتی که از این اُلفین ها تولید می شود، بالا و رو به فزونی است. چون منابع فسیلی (طبیعی) فاقد الفین های سبک می باشند و بیشتر آنها شامل هیدروکربن های اشباع شده و آروماتیکها می باشد، روش های سنتزی برای تولید اُلفین های سبک اجتناب ناپذیر است. یکی از راههای تولید اُلفینهای سبک، هیدروژن زدایی آلکان متناظر- حذف یک مولکول - با آنها می ب...

Early pregnancy detection in dairy cattle is an integral part of a successful animal husbandry practice. A simple seed germination technique (Punyakoti test) comprises observation of differential seed germination response of wheat seeds to diluted fresh urine samples as reflected by significant inhibition of germination percentage in pregnant cow urine when compared to non pregnant cow urine. H...

To understand gene expression networks leading to functional properties and compositional traits of the soybean seed, we have undertaken a detailed examination of soybean seed development from a few days post-fertilization to the mature seed using Illumina high-throughput transcriptome sequencing (RNA-Seq). RNA was sequenced from seven different stages of seed development, yielding between 12 m...

s Quantum dots are inorganic nanocrystal semiconductors that behave exceptionally well as fluorophores and find ample applications in electronics, chemical and bio-medical researches and mass production. From the last two decades lot of efforts have been employed to invent a newer method for its preparation that will be beneficial over the conventional one. In this review articles emphasis has ...
