Several studies suggest that some maternal factors such as prim gravids,elderly pregnancy, some occupations, previous high blood pressure, kidneys diseases, diabetes and some medical other diseases...

let  be a banach algebra and  a derivation. in this paper, it is proved, under certain conditions, that , where  is the jacobson radical of . moreover, we prove that if  is unital and  is a continuous derivation, then , where  denotes the set of all primitive ideals such that  is commutative,  denotes the set of all maximal (modular) ideals such that  is commutative, and  is the set of all non-...

key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. to establish a secure communication, two nodes must share common key from their key-rings. otherwise, they can find a key- path in which ens...

background: clinical education with patient-focused learning is very important in medical education. therefore, it is very essential to select an appropriate education method. the current study was conducted to analyze the impact of simultaneous presentation of medical stager and inter in seminars provided with a pre-organizer strategy and from the students' perspective (2012-2013).  metho...

a chelating resin of polystyrene divinylbenzene resin functionalized by 1-(2-pyridylazo) 2- naphtol (psdvb-pan) has been synthesized and its sorption properties have been investigated for preconcentration and determination of cadmium at μg/l level by flame atomic absorption spectrometry. the procedure is based on the sorption of cd(ii) ions on a minicolumn of synthesized chelating resin. the re...

background: pre-pregnancy care is considered as the services assessing and reducing the pregnancy risks through providing medical care and mental support. therefore, a pre-pregnancy counseling protocol was prepared based on a series of guidelines. this study aimed to determine the effect of the protocol on pregnancy and labor indices. methods: this was a four-phase field study conducted in four...

conclusions in comparison with road traffic accidents on city streets, trauma patients in rtas on roads out of the city have longer pre-hospital time intervals and more severe injuries; therefore this group needs more pre-hospital resuscitation interventions. results findings of this study showed that, 75% of rtas occurred on city streets (n = 1 251). motor-car accidents were the most frequent ...

background: it has been documented that cytokines play important roles in the induction of normal functions of the placenta. it has been hypothesized that abnormal expression of the cytokines may be associated with unsuccessful pregnancy. objective: the aim of this study was to compare the serum levels of interleukin-17a (il-17a) and tumor growth factor (tgf-ß) in pre-term, term neonates, and t...

In this paper, some categorical properties of the category { Pre-Dcpo} of all pre-dcpos; pre-ordered sets which are also pre-directed complete, with pre-continuous maps between them is considered. In particular, we characterize products and coproducts in this category. Furthermore, we show that this category is neither complete nor cocomplete. Also, epimorphisms and monomorphisms in {Pre-Dcpo} ...
