An effective measure for controlling the most harmful wintering and winter weed species, such as Apera spica-venti, Galium aparine, Veronica persica, Consolida regalis, Capsella bursa-pastoris, Descurainia Sophia, Vicia villosa, etc. in wheat crops is autumn application of herbicides, especially early stages crop development, starting from seed germination stage, when it sensitive to their pres...

The Romanian hamster Mesocricetus newtoni is endemic to South-Eastern Romania (Dobruja region) and North-Eastern Bulgaria, prefers steppic, arid, uncultivated habitats, but also found in alfalfa fields, less often corn cultures field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this cryptic species. one family group (one female four pups) was mon...

in order to evaluate the effects of yield and yield components and weed diversity and density in row intercropping for wheat and canola, a field experiment was conducted based on a complete randomized block design with three replications at the agricultural research station of ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments included four pa...

This paper studies dimensional visibility representations of graphs in which objects in d correspond to vertices and vertical visibilities between these objects correspond to edges We ask which classes of simple objects are universal i e powerful enough to represent all graphs In particular we show that there is no constant k for which the class of all polygons having k or fewer sides is univer...

Operator splitting techniques were originally introduced with the main objective of saving computational costs. A multi–physics problem is thus split in subproblems of different nature with a significant reduction of the algorithmic complexity and computational requirements of the numerical solvers. Nevertheless, splitting errors are introduced in the numerical approximations due to the separat...

purchased. Too often, this leads to the decision to use the chemicals ‘just in case’ even when their application may cause more harm than good. Alternatives that could be used as part of an IPM strategy include crop rotation and diversity, inter-row planting, management of planting schedules, tillage and irrigation according to the minimisation of pest dangers, and biological strategies, such a...

Background & Aim:The main aim of this study was stabilizing D. Sophia beverage and reduce its sedimentation rate. Experimental: Xanthan and Carboxy methyl cellulose gums have been used in three levels (0.05, .01 and .02 gr/lit) and mixture of Guar-xanthan and carboxymethyl cellulose (each .1 g/l) and extracted dried gum from D. Sophia in (1, 2 an...
