high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

dead yeast cells are an abundant residue of the brazilian ethanol industry and the industries still don’t have a proper or desirable destiny for all these cells, which means tons of vitamins and proteins that have not a major end. in the other hand, heavy metal residues are a problem, especially for leather industry, where brazil is also a great producer. in this work, dead yeast cells were use...

residue number system (rns) is a non-weighted number system for integer number arithmetic, which is based on the residues of a number to a certain set of numbers called module set. the main characteristics and advantage of residue number system is reducing carry propagation in calculations. the elimination of carry propagation leads to the possibility of maximizing parallel processing and reduc...

abstract in order to evaluate the effects of rice conventional herbicides on rotational second crops (lettuce, cress, clover, canola and radish), soil microbial biomass and diversity, a field and glasshouse experiments were conducted in mazandaran province and research glasshouse of ferdowsi university of mashhad, respectively. five experiments were carried out for 5 second crop separately with...

carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...

In this paper, a new method is introduced for improving the efficiency of the Residue Number System, which uses both binary and residue representations in order to represent a number. A residue number system uses the remainder of the division in several different modules. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

a gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. the selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their mrl is issued by “the institute of standards of iran” and propoxur whic...

residue number system (rns) is a carry-free and non-weighed integer system. in this paper an improved three-moduli set  in reverse converter based on crt algorithm is proposed. crt algorithm can perform a better delay and hardware implementation in modules via other algorithms. this moduli is based on p that covers a wide range on modules and supports the whole range of its modules in dynamic r...

a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...
