In recent decades, a number of protocols for Remote data integrity checking(RDIC) have been proposed. Identity(ID) based RDIC protocols are constructed to guarantee cloud data integrity and data privacy. The known protocols for RDIC always assume that the Private key generator(PKG) is a trusted one, but in real-world applications by corrupt PKG, malicious Cloud server(CS) can easily cheat the third party auditor that the data owner’s outsourced data are kept safe through the data has been deleted or altered. In this paper, we explore the novel model of RDIC with untrusted PKG and malicious CS, by employing the partial key method and Authentication, authorization, accounting(AAA) *** construct a new ID-based RDIC, which provides the ID revocation and key updation. The experimental evaluations show that our scheme is more efficient than known ones.

Regolith thickness is considered as a contributing factor for the occurrence of ***, mostly it is ignored because of complex nature and as it requires more time and resources for investigation. This study aimed to appraise the role of regolith thickness on landslide distribution in the Muzaffarabad and surrounding areas, NW *** this purpose regolith thickness samples were evenly collected from all the lithological units at representative sites within different slope and elevation classes in the field. Topographic attributes(slope, aspect, drainage, Topographic Wetness Index,elevation and curvature) were derived from the Digital Elevation Model(DEM)(12.5 m resolution).Arc GIS Model Builder was used to develop the regolith thickness model. Stepwise regression technique was used to explore the spatial variation of regolith thickness using topographic attributes and lithological units. The derived model explains about 88% regolith thickness variation. The model was validated and shows good agreement(70%) between observed and predicted values. Subsequently, the derived regolith model was used to understand the relationship between regolith thickness and landslide distribution. The analysis shows that most of the landslides were located within 1-5 m regolith thickness. However, landslide concentration is highest within 5-10 m regolith thickness, which shows that regolith thickness played a significant role for the occurrence of landslide in the studied area.

In this paper, the MHD peristaltic flow inside wavy walls of an asymmetric channel is investigated, where the walls of the channel are moving with peristaltic wave velocity along the channel length. During this investigation,the electrical conductivity both in Lorentz force and Joule heating is taken to be temperature dependent. Also, the long wavelength and low Reynolds number assumptions are utilized to reduce the governing partial differential equations into a set of coupled nonlinear ordinary differential equations. The new set of obtained equations is then numerically solved using the generalized differential quadrature method(GDQM). This is the first attempt to solve the nonlinear equations arising in the peristaltic flows using this method in combination with the Newton-Raphson technique. Moreover, in order to check the accuracy of the proposed numerical method, our results are compared with the results of built-in Mathematica command NDSolve. Taking Joule heating and viscous dissipation into account, the effects of various parameters appearing in the problem are used to discuss the fluid flow characteristics and heat transfer in the electrically conducting fluids graphically. In presence of variable electrical conductivity, velocity and temperature profiles are highly decreasing in nature when the intensity of the electrical conductivity parameter is strengthened.

分散式污水处理系统作为适用于低密度社区污水处理的解决方案已经引入,而污水处理系统无法使用。农村地区的分散式污水处理系统对于防止水环境污染非常重要。日本的污水处理技术(Johkasou)已经进行了研究,以评估中国餐饮废水治理的可行性,并且其去除效率符合污水排放指南。本研究基于低成本分散式处理系统Johkasou对CODCr,NH3-N,TP和TN去除效率的评估,以评估中国餐饮废水处理的可行性。本研究包括餐饮废水的特点,系统的去除效率和处理系统在不同季节和时间内的机理,以确定时间变化。此外,处理系统由三个隔室组成,厌氧,需氧和消毒,具有不同的去除能力,以确定每个隔室的不同指数。在夏季,秋季,冬季和冬季期间,餐饮废水中CODCr的进水浓度范围为244 至 1035 mg/L,NH3-N 为 7.0 至 30.6 mg/L,TP 为 1.33 至 4.74 mg/L,TN为12.2至43.6 mg/L春季。该处理系统正在利用微生物的活性进行操作,以去除餐饮废水中的这些指标,分别为CODCr56%,NH3-N12.3%,TP12.2%和TN11.6%的去除效率。这项研究显示其三个指标的最高去除效率在夏季,但是CODCr去除率最高的是夏季和秋季。此外,处理系统的每个隔室的平均去除效率分别为73%,NH3-N33%,TP25%和TN32%。我在研究期间的这项研究的目的是关于Johaksou在中国餐饮废水上的应用。本研究论文分别介绍了相关研究的总体介绍,文献综述,具体介绍,材料与方法,结果与讨论,各章的发现与结论。

The role of the leaves of Robinia pseudoacacia L., which is widely distributed in the arid lands, on improving soil physical and chemical properties was analyzed at various incubation periods. The incubated soils added with 0, 25, 50 and 75 g Robinia pseudoacacia leaves were tested after consecutive incubation intervals of 6, 8 and 10 months and the different soil parameters were measured. The results showed the increases in organic matter (OM), extractable K, cation exchange capacity (CEC), aggregate stability and water holding capacity, but the decreases in pH value and bulk density after 6 months’ incubation. The gradual decrease in change rates of soil properties indicated less microbial population and organic residual mineralization under acidic conditions, which were resulted from fast decomposition of leaves after the first 6 months incubation. The increases in soil organic matter content, extractable K, CEC, aggregate stability and water holding capacity and the decreases in soil pH and bulk density provide favorable conditions for crop’s growth.
