The Internet of Things (loT) promises to be the next big revolution of the World Wide Web. It has a very wide range of applications, ranging from smart cities, smart homes, monitoring radiation levels in nuclear plants, animal tracking, health surveillance and a lot more. When nodes in wireless sensor networks are monitored through internet it becomes a part of Internet of Things. This brings in a lot of concerns related to security, privacy, standardization, power management. This paper aims at enhancing security in smart home systems. Devices like thermostat, air conditioners, doors and lighting systems are connected with each other and the internet through the internet of things technologies. Encryption and hash algorithms areproposed in this paper through which devices in the loT can securely send messages between them. Encryption algorithm is used to ensure confidentiality as the attackers cannot interpret the cipher text that is sent. In order to ensure integrity (cipher text is not changed) hash algorithm is used.

Earth block is a construction material made primarily from soil. Compressed earth blocks have been widely used to construct many older structures which was found more economical. The present study involves the use of different admixtures which can improve the compressive strength of the pressed composite earth brick. As soil is abundant in nature, the compressed earth bricks can be manufactured in large quantity. By using this method, buildings of uniform component sizes can be made which leads to faster construction with lesser cost. The surface of building can be finished with clay mortar or cement mortar.

Employee attrition can become a serious issue because of the impacts on the organization’s competitive advantage. It can become costly for an organization. The cost of employee attrition would be the cost related to the human resources life cycle, lost knowledge, employee morale, and organizational culture. This study aimed to analyze employee attrition. The result obtained can be used by the management to understand what modifications they should perform to the workplace to get most of their workers to stay. The data for the study were around one thousand four Hundred employees. I collect the employee details from the organization and using Power BI for making visuals with the use of various kind of charts and analyzing the employee attrition using SPSS. The study has six steps: (1) data collection, (2) data pre-processing, (3) data analysis, (4) Making Visuals, (5) Identifying key factors, (6) Generate insights and recommendation, and (7) Analysis using SPSS. Remember that each organization's attrition analysis process may vary based on specific goals, available data, and resources. It's important to tailor the analysis approach to meet the unique needs of your organization.

The release of corrosion debris from metallic implants leading to adverse tissue reactions and pain has jeopardized the lives of patients. This study attempts to observe if this holds true for widely used cost efficient stainless steel fracture plates and screws by studying the microenvironment in the peri prosthetic tissue of the retrieved implants. Fracture plates and nails along with adjacent tissues were collected in 10% neutral buffered formalin. Cellular response was qualitatively evaluated using HE staining and debris distribution was semi-quantitatively graded. Elemental composition of metallic debris was analysed by ESEM-EDAX of the tissue sections. The presence of macrophages, endothelial cells, TLR-4 and HIF-1α were quantitated by Immunohistochemistry and histomorphometry. Analysis of TLR-4 gene expression was carried out by real time PCR and the presence of a hypoxic milieu was confirmed by PCR Array. This study demonstrates the corrosion debris initiated chronic inflammatory reaction to stainless steel fracture plates. Nickel and Chromium ions released from implants induce a hypoxic environment resulting in TLR-4 induction. These results emphasize the need for identification of potential biomarker that could serve as a deciding factor for removal of stainless steel fracture plates from patients prior to the onset of inflammation associated reaction and also suggest the use of better manufacturing techniques and newer bio resorbable implants.
