The axisymmetric acoustic wave propagating in a perfect gas with a shear pipeline flow confined by a circular rigid wail is investigated. The governing equations of non-isentropic and isentropic acoustic assumptions are mathematically deduced while the constraint of Zwikker and Kosten is relaxed. An iterative method based on the Fourier-Bessel theory is proposed to semi-anaiyticaily solve the proposed models. A comparison of numerical results with literature contributions validates the present contribution. Meanwhile, the features of some high-order transverse modes, which cannot be analyzed based on the Zwikker and Kosten theory, are anaiyzed

The estimation of key rate is an important aspect of the quantum key distribution process, especially in the use of dead time. In this paper, we demonstrate a numerical simulation to estimate the average detection probability and the key rate. Using our method, the estimated average detection probability is better than the previous result. Besides, we can easily find the best dead time, especially when considering the impact of after pulse.

The triple-differential cross section （TDCS） for the （e,2e） ionization of a hydrogen molecule is calculated using the molecule distorted-wave Born approximation （MDWBA）. Distorted waves are obtained by solving momentum-space coupled-channel Lippmann-Schwinger equations, including the ground state and the lowest-lying electronic state of b3Σu . TDCSs at the incident energy 100 eV in coplanar asymmetric geometry are reported. The present calculations are compared with the available experimental measurements and the theoretical results.

S100 calcium binding protein A8 (S100A8),a possible novel member of NF-kappa B signal pathway in laryngeal squamous cell carcinoma (LSCC),interacts with human leukocyte antigen B (HLA-B) which carries an NF-kappa B binding site within the enhancer A. The objective of this study was to explore the molecular mechanism of S100A8 in laryngeal carcinogenesis. RT-PCR,Western blotting and immuno-histochemistry staining were applied to evaluate the expression levels of IKKα,P65,REL-B,S100A8,APAF-1 and BCL-2 genes. The signal transduction passway in which S100A8 might participate was explored by RNA interference. Flow cytometry,TUNEL assay and cell invasion in vitro were used to detect the biological behavior of Hep2 cells induced by S100A8 gene. Our results showed that high expression of S100A8 was related to tumorigenesis in LSCC and negatively correlated with the degree of differentiation,indicating that S100A8 gene could inhibit apoptosis and promote metastasis in LSCC. Additionally,the suppression of S100A8 by RNA interference down-regulated BCL-2 but not APAF-1,P65 and IKKα,while,the suppression of P65 could significantly down-regulate the expression of S100A8 gene. In conclusion,S100A8 plays an important role in P65/HLA-B/S100A8/BCL-2/Caspase-9 (-3) pathway in laryngeal carcinoma.

The adverse impact of chemical agriculture in the India on the soil, water, environment and human health （of consumers and farm families） exacerbates rural poverty, even as agriculture productivity remains low. Poor families, especially women, are the most affected by the health and environmental risks that are brought on by chemical agriculture, and they are hardest hit by the deteriorating productivity. On the other hand, the solid waste management problem in India is increasingly being felt in rural and urban areas. In this study, the author proposes to practice ofvermicomposting as technology for both sustainable agriculture and solid waste management, using the Hydro Bioreactor with vegetable waste. This technique is studied in the present research work which is simple and potentially inexpensive. Experiments were conducted to determine the changes in the physicochemical parameters and the dominant species of microorganisms at different temperatures during entire process of vermicomposting were investigated. The vermicompost developed in the hydro bioreactor was found to have comparatively high value of nutrients which can serve as natural fertilizer. The hydro bioreactor vermicomposting has proved very effective and efficient for developing compost from vegetable waste.

Climate change is described as the most universal and irreversible environmental problem facing the planet Earth. While climate change is already manifesting in Ethiopia through changes in temperature and rainfall, its magnitude is poorly studied at regional levels. The objective of this paper was to assess and quantify the magnitude of future changes of climate parameters using Statistical Downscaling Mode (SDSM) version 4.2 in Amhara Regional State which is located between 8°45‘N and 13°45‘N latitude and 35°46‘E and 40°25‘E longitude. Daily climate data (1979- 2008) of rainfall, maximum and minimum temperatures were collected from 10 observed meteorological stations (predictand). The stations were grouped and compared using clustering and Markov chain model, whereas the degree of climate change in the study area was estimated using the coupled HadCM3 general circulation model (GCM) with A2a emission scenarios (Predictors). Both maximum and minimum temperatures showed an increasing trend;the increase in mean maximum temperature ranges between 1.55°C and 6.07°C and that of the mean minimum temperature ranges from 0.11°C and 2.81°C. While the amount of annual rainfall and rainy days decreased in the study Regions in the 2080s. The negative changes in rainfall and temperature obtained from the HadCM3 model in the current study are alarming and suggest the need for further study with several GCM models to confirm the current results and develop adaptation options.
