Introduction: To cope with natural and unnatural critical events such as air crashes, car accidents, chemicals and earthquakes or floods needs powerful resource management. Some of these critical events are tiny and by using local and available resources management could be resolved, but some cover extended geographical areas and so need a massive, vast resources and high level management for e...

a new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. the catalytic activity of this dimeric [pd{c6h2(-ch=noh)-(ome)2-2,3}(µ-cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in mizoroki–heck cross ...

Solubility prediction of high molecular weight molecules in high-pressure solvents is an interesting field of research. Sometimes the solubility data are not available for several components due to lacking of valid equipments. Therefore, an accurate prediction technique can help the researchers. According to the literature, the simple Equations of State (EoSs) such as Soave-Redlich-Kwong (SRK),...

this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...

the neoplastic niche comprises complex interactions between multiple cell types and molecules requiring cell-cell signaling as well as local secretion. these niches are important for both the maintenance of cancer stem cells and the induction of neoplastic cells survival and proliferation. each niche contains a population of tumor stem cells supported by a closely associated vascular bed compri...

In this study, we investigated on a systems level how complex protein interactions underlying cell polarity in yeast determine the dynamic association of proteins with the polar cortical domain (PCD) where they localize and perform morphogenetic functions. We constructed a network of physical interactions among >100 proteins localized to the PCD. This network was further divided into five robus...

a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
