The availability of low-cost network interface cards (NICs) has made the IEEE 802.11 medium access control (MAC) protocol the de facto MAC standard for wireless mobile ad-hoc networks. Although the IEEE 802.11 MAC protocol is designed to have stations share a single channel in a network, many of the IEEE 802.11 physical (PHY) layer standards define multiple channels and allow the simultaneous, ...

The pro-apoptotic Bcl-2-family protein Bim belongs to the BH3-only proteins known as initiators of apoptosis. Recent data show that Bim is constitutively inserted in the outer mitochondrial membrane via a C-terminal transmembrane anchor from where it can activate the effector of cytochrome c-release, Bax. To identify regulators of Bim-activity, we conducted a search for proteins interacting wit...

The rational use of valuable fish species from aquaculture is difficult to implement without knowledge the state genetic structure local stocks. Different types DNA markers can be used achieve goals selection and breeding work. a stock rainbow trout (Oncorhynchus mykiss Walbaum, 1792) (Salmoniformes, Salmonidae) farmed in Ukraine was studied using DNA-markers: microsatellite (SSR-markers – simp...

Recently, a model was proposed to assess hepatic insulin sensitivity during a meal, i.e., the ability of insulin to suppress glucose production (EGP), SI (P). The model was developed on EGP data obtained from a triple-tracer meal and the tracer-to-tracee clamp technique and validated against the euglycemic hyperinsulinemic clamp. The aim of this study was to assess whether SI (P) can be obtaine...

The paper presents an approach for the on-line monitoring and diagnosis of multi-robot systems where services are provided by a team of robots and the environment is only partially observable via a net of fixed sensors. This kind of systems exhibits complex dynamics where weakly predictable interactions among robots may occur. To face this problem, a model-based approach is adopted: in particul...

Measuring insulin sensitivity during the physiological milieu of oral glucose perturbation, e.g., a meal or an oral glucose tolerance test, would be extremely valuable but difficult since the rate of appearance of absorbed glucose is unknown. The reference method is a tracer two-step one: first, the rate of appearance of glucose (R(a meal)(ref)) is reconstructed by employing the tracer-to-trace...

The mitochondrion has evolved as an important organelle in determining cell survival and cell death. It is involved in a plethora of processes in mammalian cells including ATP production, steroid synthesis, and cell division and cell death. Indeed, mitochondrial dysfunction is associated with numerous human maladies including heart disease. Mitochondrial diseases have traditionally been attribu...

Two types of sabkhas are distinguished in the study coastal area; first type was developed at mouths wadis where sea water enters through high tides; these include; Omm El-Shawesh, Wadi Al-Ain sabkha and Rizk sabkha. A generalized hydrodynamic model for formation this constructed. The second is stretching behind dunes, divided into a longitudinal strip from east to west saline crusts appear som...
