Within the wireless mesh network, a bottleneck problem arises as the number of concurrent traffic flows (NCTF) increases over a single common control channel, as it is for most conventional networks. To alleviate this problem, this paper proposes a two-stage coordination multi-radio multi-channel MAC (TSC-M2MAC) protocol that designates all available channels as both control channels and data c...

Soil acts as a source of continuous radiation exposure to human and as a medium of migration for transfer of radionuclides to the biological systems hence causes the radiological contamination in the environment. So, it is necessary to study the natural radioactivity in soil to assess the dose due to terrestrial gamma radiation levels in order to know the health risks. The Primordial Radioactiv...

Neu robiological studies ind icate very p recise tempo ral behavior of neuron firings. Abeles [1] has recorded spik e timing of different co rtical cells and, in particular, has observed th e following level of precisio n: when a neuron A fires, neuron B w ould fire 15 1ms later an d neu ron C would fire p recisely 289 ms after that—with a precision across trials of 1 ms! Such lon g delays req ...

We consider Quantum OBDD model. It is restricted version of read-once Quantum Branching Programs, with respect to “width” complexity. It is known that maximal complexity gap between deterministic and quantum model is exponential. But there are few examples of such functions. We present method (called “reordering”), which allows to build Boolean function g from Boolean Function f , such that if ...

Ovarian steroid metabolism was investigated (i) during development in a normal inbred strain in which post-natal follicle growth has been described and (ii) in adult hypogonadal (hpg) mice which lack GnRH and have very low serum concentrations of gonadotrophins. Tissue was incubated with [3H]pregnenolone or [3H]androstenedione and metabolites separated by t.l.c. or h.p.l.c. Progesterone was the...

The preservation quality of buffalo semen is poor. The possibility that the cause is inherent in the enzyme system of the spermatozoa and seminal plasma has not so far been systematically studied. There are a few reports on acid and alkaline phosphatase (Eapen, Shrivastava & RazaNasir, 1946; Roy, Pandey & Rawat, 1960; Sengupta, Misra & Roy, 1963; Misra, Singh & Tomar, 1969), but no reports appe...

Much ~ been written m recent years of the relative advantages and chsadvantages of new intravenous anaesthetics. Such comparisons are always difficult to make because of the many variables which ca~Lnot be easily controlled in a clinical series. For that reason, we attempted some time ago to compare a number of intravenous agents in human vol~mteers, a&a~inistering each drug consecutively to th...
