Assessment of the air pollutants on automobiles emission dispersion: the effects of barrier height and the road surface temperature.

In the paper, a mathematical model was constructed that describes the specifications of the wind flow and the dispersion of pollutants, taking into account the variable temperature on the roadway surface, which varies depending on the time for some quarter of the city of Almaty. The impact of the traffic tidal flow was studied based on the data of measuring passing vehicles as a source of pollution by the CFD and on the spatial distribution of pollutants for various types of pollution. A test problem was performed to validate the numerical algorithm and the mathematical model.

[Experience of using Experience of using NefroBest-N for rehabilitation of patients undergoing radical laparoscopic cystectomy].

Aim: To evaluate the efficacy and safety of NefroBest-N in patients undergoing to the radical cystectomy with neobladder formation.

Materials And Methods: A total of 60 patients with invasive bladder cancer aged 56 to 75 years, treated at A.I.

Control of current and voltage oscillations in a short dc discharge making use of external auxiliary electrode.

A dc discharge with a hot cathode is subject to current and voltage plasma oscillations, which have deleterious effects on its operation. The oscillations can be inhibited by installing an auxiliary electrode, placed outside of anode. By collecting a modest current through a small opening in anode, we show that the discharge becomes stable, in a certain pressure range.

[Diagnosis of intermuscular lipomas in children].

According to the data of literature intermuscular lipomas are observed in children, but rarely. The diagnosis of intermuscular lipomas presents certain difficulties since these tumors are frequently taken for sarcomas. Biopsy seems to be an important diagnostic method.
