We present preliminary results from the experimental investigation of the response of the atmosphere due to the impact of powerful sh.ck waves. The response is evidenced as ultra low frequency electromagnetic wave radiation at frequency of 2-5 kHz and in duration of 3 7s. We hypothesize that this radiation appears due to the following process： the sh.ck wave ionizes the neutral particles in the air and these charged and neutral particles continue their vertical motion, which forms in the trail of the sh.ck wave. Such motion can cause the cyclotron-like radiation measured.

The previously derived Lane consistent dispersive coupled-channel optical model for nucleon scattering on 232Th and 23Su nuclei is extended to describe scattering on even-even actinides with Z=90-98. A soft-rotator- model （SRM） description of the low-lying nuclear structure is used, where the SRM Hamiltonian parameters are adjusted to the observed collective levels of the target nucleus. SRM nuclear wave functions （mixed in K quantum number） have been used to calculate the coupling matrix elements of the generalized optical model. The ＂effective＂ deformations that define inter-band couplings are derived from the SRM Hamiltonian parameters. Conservation of nuclear volume is enforced by introducing a dynamic monopolar term to the deformed potential, leading to additional couplings between rotational bands. The fitted static deformation parameters are in very good agreement with those derived by Wang and collaborators using the Weizs^cker-Skyrme global mass model （WS4）, allowing use of the latter to predict cross sections for nuclei without experimental data. A good description of the scarce ＂optical＇experimental database is achieved. SRM couplings and volume conservation allow a precise calculation of the compound-nucleus formation cross sections, which is significantly different from that calculated with rigid-rotor potentials coupling the ground-state rotational band. The derived parameters can be used to describe both neutron- and proton-induced reactions.

In this paper, we investigate the flow of customers through queuing systems with randomly varying intensities. The analysis of the Kolmogorov-Chapman system of stationary equations for this model sh.wed that it is not possible to construct a convenient symbolic solution. In this paper an attempt is made to circumvent this requirement by referring to the ergodicity theorems, which gives the conditions for the existence of the limit distribution in the service processes, but do not require knowledge of them.

We have measured the angular distributions for 12C ion beam elastically scattered from 12C target of thickness 17.4 μg/cm2 at energies 15, 18 and 21 MeV which is close to the Coulomb barrier energy for 12C + 12C nuclear system. The elastic scattering of 12C beam on 12C was analysed also at different energies (139.5, 158.8, 180, 240, 288.6, 300, 360 and 420 MeV) from literature in order to obtain the global optical potential parameters, which could fairly reproduce the experimental data. The experimental results were analysed within the framework of both the optical model and the double folding potential obtained with different density-dependent NN interactions which give the corresponding values of the nuclear incompressibility K in the Hartree-Fock calculation of nuclear matter. The agreement between the experimental results and the theoretical predictions in the whole angular range is fairly good.

The area is a part of the Egyptian Eastern Desert in the northwestward to the Gulf of Suez. It covers an area of about 542 square kilometers. Wadi Bada’a is devoid of vegetation, because of the arid climate and water scarcity. However, the present study concerns the flash.flood and its impact on the industrial zone and connected road at wadi Bada’a. In this work, the bivariate statistical method using frequency ratio was used to evaluate the areas of potential risk. Geographic Information System package (GIS) was used to analyze and calculate different data sets. The different data source has been used in the research to produce a flood hazard susceptibility map of the area, including the geologic maps, Landsat-8 imagery, land use, and soil type associated with field investigation and data collection. Spatial database with elements at risk, related features and attributes at wadi Bada’a, were constructed. Training data were created randomly in the study area to create an inventory map with testing data. The inventory location of 95 location points has been created. The inventory datasets were divided into 75% of training datasets and 25% testing data. The independent flood-related factors were evaluated by analyzing each independently and assessing their impact on flooding with inventory datasets. The flood susceptibility maps were constructed-using training and testing datasets have been used to evaluate using the success rate method. The results of the accuracy assessment sh.wed a success rate of 76.6% of Area Under Curve. Therefore, the main road in the study area almost at high risk in many parts because of flash.flood, additionally the industrial activities located in the moderate risk zone.

提出一种操作简单、成本低廉的制备WC-Al_2O_3复合粉末的方法。热力学计算表明,WO_3:xAl:(4-1.5x)C混合体系中WO_3在铝热还原反应过程放出大量的热量,促进了此体系中的碳热还原反应(吸热反应)。用碳原子部分取代铝原子阻止了副产物W_2C的形成,这是由于它在较低温度下具有较低的热力学稳定性。为验证本文作者所提出的反应机理,在微波炉中对不同WO_3:xAl:(4-1.5x)C(1.1≤x≤2)混合物进行热处理。结果表明,当1.4≤x≤2时,反应类型为自蔓延高温合成反应,WO_3:xAl:(4-1.5x)C混合体系中少量Al导致大量WC的产生;当混合体系中x=1.4 mol时,体系经过自蔓延高温合成反应后,在密封环境下连续进行微波加热能获得不含W_2C的WC-Al_2O_3复合物;当x≤1.3时,由于反应不完全以及剩余的反应物,上述反应变得缓慢。
