Organic dye pollutants present in wastewater pose a significant global challenge. Among pollutants, the synthetic dye rhodamine B(rB) stands out due to its non-biodegradable nature and associated neurotoxic, carcinogenic,and respiratory irritant properties. Extensive research has been conducted on the efficacy of adsorption and photodegradation techniques for the removal of rB from wastewater. While adsorption and advanced oxidation processes(AOPs) have gained considerable attention for their effectiveness in recent years, the underlying behaviors and mechanisms of these technologies remain incompletely understood. Therefore, a comprehensive of recent research progress in this domain is imperative to clarify the basics and present the up-to-date *** review provides an in-depth exploration of the fundamentals, advancements, and future trajectories of rB wastewater treatment technologies, mainly encompassing adsorption and photodegradation. This work starts with a general introduction of outlining the sources, toxicity, and diverse applicable removal strategies. Subsequently, it thoroughly examines crucial techniques within non-photochemical, photochemical, and adsorption technologies, such as UV light assisted AOP, catalyst assisted AOP, ozonation, Fenton system, electrochemical AOP, and adsorption technology. The primary objective is to furnish a broad overview of these techniques,elucidating their effectiveness, limitations, and applicability. Following this, the review encapsulates state-of-theart computational simulations pertaining to rB adsorption and interactions with clays and other ***, it delves into column adsorption of rB dye, and elucidates various influencing factors, including bed height, feed concentration, pollutant(rB) feeding or flow rate, and column regeneration. This panoramic review aims to provide valuable insights into suitable techniques, research gaps, and the applicability of nonphotochemical, photochemical, and

The objective of this research is to study the dry sliding wear behaviour of metal surfaces and influences of their surface hardness. The improved hardness of the TiN deposited surface was about 1763 Hv. The worn surface Scanning Electron Microscope (SEM) morphology exhibits the surface damage due to varying wear test parameters. The Electron Dispersive Spectroscopy (EDS) reveals that the material transfer between the counter parts and the wear mechanism has been involved. The minimum specific wear rate of TiN surface was 0.0018 mg/Nm and 0.0026 mg/Nm against Ti6Al4V alloy and TaN respectively.

researches related to wireless sensor networks primarily concentrate on routing, Location Services, Data Aggregation and Energy Calculation Methods. Due to the heterogeneity of sensor networks using the web architecture, cross layer mechanism can be implemented for integrating multiple resources. Framework for Sensor Web using the cross layer scheduling mechanisms in the grid environment is proposed in this paper. The resource discovery and the energy efficient data aggregation schemes are used to improvise the effective utilization capability in the Sensor Web. To collaborate with multiple resources environment, the grid computing concept is integrated with sensor web. resource discovery and the scheduling schemes in the grid architecture are organized using the medium access control protocol. The various cross layer metrics proposed are Memory Awareness, Task Awareness and Energy Awareness. Based on these metrics, the parameters-Node Waiting Status, Used CPU Status, Average System Utilization, Average Utilization per Cluster, Cluster Usage per Hour and Node Energy Status are determined for the integrated heterogeneous WSN with sensor web in Grid Environment. From the comparative analysis, it is shown that sensor grid architecture with middleware framework has better resource awareness than the normal sensor network architectures.

现在移动手机的使用已经在我们日常生活中广泛地传播，我们利用移动手机作为照相机，收音机，随身听以及浏览网络的工具。由于大部分的网页是为桌面计算机设计的，很难用小的屏幕设备来浏览它们。因此，计算机科学领域兴起了极大的兴趣把具有丰富内容的网页嵌入到我们移动设备小屏幕上。由于移动设备的屏幕较小，输入设备使用困难，因此用户希望只要一次搜索就能达到目的。但是，每个Web网页都有很多小模块，而不同的部分对于终端用户来说有不同的重要性，因此，如何利用最便捷的方式来确定终端用户最感兴趣的网页部分，并保证信息集成完整而不会产生信息损失，是一项值得研究的内容。与屏幕相关的两个缺点是：分辨率过低，因此一些促使像素提升的方法并不凑效;过多的网页内容导致显示的不方便。移动搜索系统采用客户端-服务器架构来满足移动浏览的要求。在客户端，开启一个Lobo驱动器实例在屏幕上等待用户的搜索请求，当一个请求发生，用户选择其中一个结果，服务器便开始计算。服务器首先从客户端接收UrL和关键词，然后服务器把UrL发送给一个解析函数对HTML代码进行解析，并把它转化成文档对象模型（DOM）表示。前向遍历DOM树，得到节点信息并进行停用词过滤和词干提取处理，保证得到所有根词。保存所有的根节点并计算各自的TF-IDF值，然后服务器可以计算网页各部分的后验概率值。这时，可以通过比较关键词与根节点来发现需要的值。计算关键词的后验概率值并与网页各部分的概率值进行比较，最终得出可以向用户展示的最合适部分。结果显示，该方法表现出很好的准确性，不过随着关键词的长度增长，虽然发现重要部分的时间不会显著增加，但准确性会有一定下降。

Nephrolithiasis is increasing in developed and developing countries at an alarming rate. With the global spike in kidney stone diseases, it is crucial to determine what risk factors are influencing the current global landscape for kidney stones. Our aims for this review are: to identity and analyze the four categories of risk factors in contributing to the global scale of stone formation: lifestyle, genetics, diet, and environment; and discuss preventative measures for kidney stone formation. We also performed data search through the published scientific literature, i.e., PubMed~? and found that there is a significant link between lifestyle and obesity with cases of calcium stones. Food and Agriculture Organization of the United Nations and World Health Organization factor indicators for dietary intake and obesity, along with climate data were used to create the projected total risk world map model for nephrolithiasis risk. Complete global analyses of nephrolithiasis deplete of generalizations is nearly insurmountable due to limited sources of medical and demographic information, but we hope this review can provide further elucidation into confounding risk factors and preventative measures for global nephrolithiasis analysis.
