scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, plantago ovata forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in jiroft, kerman province, south of iran. as the firstfactor, drought stress included four le...

introduction: human skills, knowledge and efficiency are important factors in the success of organizations and community health centers which have a critical role in total quality management (tqm) as a management system. knowledge is necessary as a source for the organizations survival. on the other hand, in order for implementation of knowledge management, there is a need for a relatively long...

Rational application of pesticides by properly adjusting the amount of product to the actual needs and specific conditions for application is a key factor for sustainable plant protection. However, current plant protection product (PPP) labels registered for citrus in EU are usually expressed as concentration (%; rate/hl) and/or as the maximum dose of product per unit of ground surface, without...

In this paper we present an implementation of the computational method in [1] that allows ranking mathematical statements by their complexity. We introduce the complexity classes ICU,iMi¥1, and, accordingly, show that Legendre’s conjecture, Fermat’s last theorem, and Goldbach’s conjecture are in CU,1, Dyson’s conjecture is in CU,2, the Riemann hypothesis is in CU,3, and the four color theorem i...

in order to investigate the effect of various rates of phosphorus fertilizer and efficiency amount of broadcasting and banding methods on yield and yield components of corn (zea mays l.), a field experiment were arranged in a split-plot design based on a randomized complete block design with four replications at the research field, ramin agricultural and natural resources university, mollathani...

To achieve both high speed and separation efficiency in the separation of a mixture of nerve and blister agent simulants, a high-aspect-ratio micro-fabricated multi-capillary column (MCC, a 50-cm-long, 450-μm-deep, and 60-μm-wide four-capillary column) was fabricated by the application of the microelectromechanical system (MEMS) techniques. Mixtures of chemical warfare agent (CWA) simulants - d...

The aim of this research was to identify factors of morphological and basic motor status in young judoka in prediction of fighting efficiency. The subject sample included 57 judoka aged 13 to 15, who have been involved in training process for averagely three years. The sample of predictor variables included a set of 18 variables for assessing anthropometric characteristics and a set of 12 varia...

to determine sugar beet water requirement and the effect of changing the quantity of applied water on some production components, a study was carried out in ekbatan agricultural research station of hamedān, iran in four years (1994-1997) during which optimum water requirement, root and sugar yield, water use efficiency on the basis of root yield, sugar percentage and water use efficiency on the...
