introduction: evidence based medicine (ebm) is current tool in medicine to produce clinical practice guidelines from well-designed, randomized, controlled trials.  we studied knowledge, attitude and practice of evidence based medicine (ebm) of neurologist participated in the iranian congress of neurology. methods: a self administered anonymous questionnaire had been distributed and filled by ne...

The soybean aphid,Aphis glycinesMatsumura, an exotic species in North America that has been detected in 21 U.S. states and Canada, is a major pest for soybean that can reduce maximum photosynthetic capacity and yields. Our existing knowledge is based on relatively few studies that do not span a wide variety of environmental conditions, and often focus on relatively high and damaging population ...

tion and nodulation, thus reducing N2 fixation capacity (Shibles, 1998). Application of N before planting or durNitrogen application during soybean [Glycine max (L.) Merrill] ing the early growth stages can suppress the N2 fixation reproductive stages has the potential to increase soybean productivity. The objective of this study was to determine the impact of N fertilizer process. Fertilizer N...

intercropping is considered for increasing and stability of yield in per unit. in order to evaluating the effect of corn/soybean intercrop in different planting dates, a study was carried out in agricultural sciences and natural resources, university of sari, faculty of agriculture during 2005-2006. the experiment was a split plot design based on randomized complete block design with four repli...

Herbicide plays the main role in guaranteeing the quantity and quality of food. Soybean reactive oxygen species scavenging system eliminates the herbicides’ side effects on the plant by activating antioxidant enzymes, which affects the yield. So, we investigated this procedure to reveal the effect of herbicides on food production. Methods: Experiments were carried out in two locations of Alborz...

The PVM is a system for distributed processing implementations that offers tools for communication between tasks, like point to point messages and broadcasts, and tools to control the spawning of tasks. It was chosen due to the simplicity it allows in the implementation of message exchanges between the agents, and because it allows the definition of which workstation a process must run. Besides...

27 the communication subsystem ; (2) they react only after the occurrence of end-to-end QoS violation ; and (3) they react to QoS violation by renegotiating a degraded QoS and thus they are restricted to applications that can accept a varying QoS. In this paper we presented an approach which allows to recover automatically from QoS violations, and only require user/application intervention (exi...

Soybean stubble is a potentially significant residue of a crop that has attained prominence as an important cash crop, high value food crop, and also as a soil ameliorative. Soybean culture in Australia is a fledgeling yet emerging industry with crop area totalling 68,000 ha in the 1983/84 season with some 80 percent of the crop grown in subtropical regions (Desborough et al. 1984). The potenti...

This study aimed to evaluate the performance, some carcass characteristics from feedlot lambs receiving sunflower crushed (SC) in the diet on partial replacement of soybean meal. The experimental design was randomized block with four levels of SC in the diet (0, 10, 20 and 30% of dry matter (DM)). There was a linear reduction of 0.02; 0.003; 0.003 and 0.17% for each percentage unit of added SC ...
