in order to study the effects of herbicide rates of metribuzin on nodulations and growth characteristics of chickpea, a series of experiments were carried out at research greenhouses of ferdowsi university of mashhad during 2009 in a randomized complete block design with four replications. studied factors were: different doses of metribuzin herbicide (10- 25- 50- 75- 100- 125 percent of recomme...

background: previous studies indicate a high incidence of digestive cancers along southern parts of caspian sea including ma­zandaran province. the present study was conducted to further investigate time to occurrence, age distribution and pos­sible risks associated with the incidence time of digestive cancers in the above regions. methods: for this purpose the data of digestive cancer incidenc...

As the world trends towards ageing population UN (2011), there is an increasing demand and interest in using technology to increase the quality of life for elderly people. An expanding area of interest is heading towards the health care applications like wearable biometric monitoring sensors. These monitoring nodes, typically powered by batteries, have various functions like sensing & monitorin...

In this paper we deal with the two-dimensional Navier–Stokes system in a torus. The main result establishes the local null controllability with internal controls having one vanishing component. The linearized control system around 0 is not null controllable: the nonlinear term is essential to get this null controllability. Our proof uses the return method together with previous results by Fursi...

Introduction The climate is a complex system that encompasses numerous Earth surface systems, i.e. the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere. The preponderance of scientific evidence indicates that anthropogenic actions such as excess generation of greenhouse gases are causing serious climatic change. Water is a critical resource to humans, commerce, wildlife, and the ...
