The blackhole attack is one of the simplest yet effective attacks that target the AODV protocol. Blackhole attackers exploit AODV parameters in order to win route requests, and thus, attract traffic, which they subsequently capture and drop. However, the first part of the attack is often neglected in present literature, while the majority of attempts in detection focus only on the second part o...

The evidence base for computerised cognitive behavioural therapy (CCBT) for common mental health problems has expanded rapidly in recent years. Reviews and meta-analyses have produced promising findings with regard to CCBT’s effectiveness and acceptability, but developing and supporting effective and sustainable models of CCBT service implementation remains a challenge. This paper considers CCB...

We prove that the zeros of the polynomials Pm(a) of degree m, defined by Borosh and Moll via Pm(a) = 2m+3/2 π (a + 1) Z ∞ 0 dx (x4 + 2ax2 + 1)m+1 , approach the lemniscate {ζ ∈ C : |ζ − 1| = 1, Rζ < 0}, as m diverges.

In the case of elastic interaction between dislocations and point defects, complex interaction mechanisms can appear, which involve simultaneously depinning-repinning processes and dragging processes.

One of the problems modern world is air pollution by harmful substances contained in exhaust gases cars. To solve this problem, diesel, and gasoline porous particulate filters are used. However, it necessary that filter create a minimum pressure drop while maintaining high filtering capacity. The purpose study to identify feasibility discrete arrangement reduce drop. In work, we carried out det...

The self-discharge of an electric double-layer capacitor with composite activated carbon electrodes and aqueous electrolyte (1 M MgSO4) was studied in detail. Under a long-term potentiostatic charge (stabilization), decrease the discharge capacity observed region voltages exceeding 0.8 V. process consists two phases. In initial phase, cell voltage drop is due to redistribution inside electrodes...

Injury to the sciatic nerve is one of the more serious complications of acetabular fracture and traumatic dislocation of the hip, both in the short and long term. We have reviewed prospectively patients, treated in our unit, for acetabular fractures who had concomitant injury to the sciatic nerve, with the aim of predicting the functional outcome after these injuries. Of 136 patients who underw...

We studied the effects of acute external acidification on the acid-base status and plasma and red cell ion concentrations of lampreys. Mortality was observed within 24 h at pH5 and especially at pH4. The main reason for the high sensitivity of lampreys to acid water appears to be the large drop in blood pH: 0-6 and 0-8 units after 24 h at pH5 and pH4, respectively. The drop of plasma pH is much...

in order to simulate the rotating disk contactor all hydrodynamic parameters, dispersed phase hold-up, characteristic velocity, mean drop size, drop size distribution, axial mixing and mass transfer have been taken into account. mechanisms of mass transfer (stagnant, circulating, oscillating drops) were used in this study. column height found from effect of mean drop size and drop size distribu...

A 20-year-old male had full manifestation of Coffin-Lowry syndrome and 6 year history of progressively severe drop episodes. His drop episodes were precipitated by unexpected sudden auditory stimuli, and were not associated with electroencephalographical changes. The positron emission tomography disclosed metabolic reduction over bilateral temporal-parietal cortex which could contribute to his ...
