Two detector materials mica and cellulose-nitrate(cn)-85 have been used to study (14.0MeV/u) Pb + Pb reaction. Events of different multiplicities were registered in mica and cn-85 detectors using the 2π-geometry technique of solid state nuclear track detection. After removing the target material from the detectors the damaged trails in the detectors were revealed as tracks by proper chemical etching. The irradiated area of each sample was scanned and events of different multiplicities were traced. The binary events were bifurcated into elastic and inelastic events. The elastic binary events and three prong events, observed in the reaction, have been used to search out coefficients cμν in the presence of both the detectors, for the reaction under study. Using these coefficients 3- and 4-prong events have been analysed. From the detailed analysis of the results of (14.0MeV/u) Pb+Pb reaction, obtained from mica and cn-85 track detectors we observed a great resemblance of results obtained from the two detectors. combining the results of both the detectors, we report some important outcomes.

The coupled problem means fluid-structure interaction widely encountered in aviation, offshore and nuclear engineerings. The coupling method here means the combination of finite and boundary elements(FE/BE)to improve the computational effciency considerably. In this paper, a general math. Model for simulation of the wetted structure dynamic response to inter/external fluid flow is presented. In particular, the various boundary conditions for fluid region are treated sophsticatodiy. In this way, only the displacement and pressure remain to be the independent variables so that both computer cost and accuracy could be improved. The FORTRAn program package of this model has been compiled on #Univac-1110 in Madison (MAcc), USA, and on #M340S computer in Wuhan University, china. As a first approximation, in this paper a 2-D example for the ship-wave interaction analysis is illustrated.

A midlatitude squall line passed over the array of the cooperative convective Precipitation Experiment (ccOPE) on 1 August 1981. The structure and evolution of the squall line, and the correlations of the storm with surface thermodynamics and kinematic fields are investigated, mainly by using radar and surface mesonet data in ccOPE. The storm-wide precipitation efficiency is also *** squall line was of an obvious process of metabolism. Thirty-four cells formed successively in front of the primary storm and eventually merged into it during the period 1700-2010 MDT. The newest cells formed near surface equivalent potential temperature maxima, and near surface moisture flux convergence zones or / and the 'temperature break lines'. The thunderstorm rainfall, with the precipitation efficiency of 54%, lags 25-30 min behind the moisture flux convergence on the average.

The initiation and propagation of failure in intact rock are a matter of fundamental importance in rock engineering. At low confining pressures, tensile fracturing initiates in samples at 40%-60% of the uniaxial compressive strength and as loading continues, and these tensile fractures increase in density, ultimately coalescing and leading to strain localization and macro-scale shear failure of the samples. The Griffith theory of brittle failure provides a simplified model and a useful basis for discussion of this process. The Hoek-Brown failure criterion provides an acceptable estimate of the peak strength for shear failure but a cutoff has been added for tensile conditions. However, neither of these criteria adequately explains the progressive coalition of tensile cracks and the final shearing of the specimens at higher confining stresses. Grain-based numerical models, in which the grain size distributions as well as the physical properties of the component grains of the rock are incorporated, have proved to be very useful in studying these more complex fracture processes.

Objective:To investigate the pro-inflammatory cytokines profiles in in nigerian pregnant women infected with Plasmodium falciparum(***) ***:Peripheral, and placental blood samples were collected from 96 consenting volunteers comprising 76 *** infected pregnant women and 20 healthy uninfected pregnant women in ***,and subjected to ELISA for cytokines ***:Increased serum concentrations of interferon-gamma(IFn-γ) was observed in infected pregnant women than their uninfected counterparts[(31.2±20.9) pg/mL vs(1.8±0.9) pg/mL]and these differences were statistically significant(χ~2= 26.18,Pnterleukin-12(IL- 12) seen in peripheral blood of the infected pregnant women than the uninfected women[(13.9±3.6) pg/mL vs(28.4±5.28) pg/mL]respectively was not statistically significant(χ~2= 4.96,P>0.05). The interleukin-6(IL-6) was significantly elevated in infected pregnant women(81.0±26.1 pg/mL) than in the uninfected pregnant women[(25.0±5.0) pg/mL](χ~2 = 29.58,Pn all, mean cytokines concentration of IL-6,IL-12 and IFn-γin the placental blood from infected pregnant women were(53.5±23.4) pg/mL,(8.7±6.9) pg/mL and(16.4±4.0) pg/mL,respectively. The multigravidae had a higher haemoglobin level of 10.2 g/dL and birth weight of 3 000 g than the primigrivadae with lower haemoglobin level of 7.5 g/dL and birth weight of 2 430 g. conclusions:The elevated IFn-γamong the malarous pregnant women implicates it as the major cytokine mediator in the host responses to systematic *** malaria in our locality.
