The increase of population in world has led to the generation of large amount of waste products such as waste plastic. These waste plastic will remain in the environment for hundreds of years, this has become inevitable problem in the present world. There is an immediate need for solution for such problem. To bring down the waste products many methods has been proposed and one of them is usage of these waste plastic in concrete which may reduce the environmental problems up to certain extent. This work aims to study possibility of disposing waste plastic as fine aggregate in concrete. In this study waste plastic mix concrete is also reinforced with steel fiber to get advantages of fiber reinforced concrete. For this an experimental study was carried out with M25 grade of concrete to evaluate the workability and mechanical property of waste plastic mix concrete with and without the addition of steel fiber. Sand is substituted with plastic waste at a dosage up to 15% by mass and we found that 5% dosage is an optimum percentage without considerable reduction in strength. Results show that adding steel fiber we can improve the quality of waste plastic mix concrete. Thus it can be concluded that replacement of sand by waste plastic up to 5% can be utilized so that disposal of used plastic can be done and hence deficiency of natural aggregate can be managed effectively.

Solar pond is a device which entraps the impinging solar radiation and stores it as thermal energy in its salty layers. Simple salt gradient solar pond consists of three basic layers: lower convective zone, non-convective zone and last is upper convective zone. In present study a simple working experimental setup of salt gradient solar pond was fabricated equipped with thermo siphon heat exchanger of capacity of 20 l in Sobhasaria Group of Institutions, Sikar (Rajasthan) with locally available materials. Different salt concentration layers were made and Salinity gradient was established successfully. Three day field experiment was conducted by considering a 1m3 solar pond. Three different combinations of salt concentrations were considered to perform the study. Model equations are developed for density and temperature variation in solar pond by MATLAB and validated with MOGA optimization technique

Thiruvanathapuram is the capital city of Kerala state. As the city is completely effected by flood, but within in the local bodies there are few low-lying areas which are susceptible to flash flood. The urban expansion which due to the increase in population are affected by the lack of proper drainage system and also due to the uncontrolled increase in concrete space,which leads to the encroachment happening near the canal area,decrease in land such as paddy field,ponds etc.Landsat 5 and 8 images are used in the analysis to detect land use changes in the city, which gives the idea of conversion of vegetation land to built up.Digital elevation model is used in the preparation of contour maps.The result of this study shows use of landsat images in detecting the land use changes, the blue green network which has been mentioned in the master plan of Thiruvanathapuram are also discussed and the various measures which to be adopted to make the city stable to urban flash flood.

"Big Data" refers to data sets that are huge in size and/or complex. They may be evaluated computationally to reveal trends, associations and patterns, particularly connecting to human behavior and interactions wherein outdated data processing application software’s are inadequate to deal with them. There are various security challenges linked in this area and if any security breach occurs then it would result in great loss in data and reputation, as the massive volume of data is involved. In addition, traditional security mechanisms and tailored mechanisms for big data would not be sufficient. In this paper, we highlight the data security and privacy challenges proposed by various sources and proposed encryption technique in our future research. For making big data secure, techniques such as encryption must be necessary

The design project of Chemical Engineering focus on solving the problem related to a chemical or process industry. The aim of the research paper is to establish study on gaseous emission in cement industry of Sultanate of Oman. The study was concentrated on testing numerous options that may help in dropping the amount of emission from cement plants especially carbon dioxide emission. As per the investigation the suggested technology was CO2 capture and it was effective in terms of cost and maintain the production amount. According to energy and mass balance of the plant it has been found that 8700 tons/day of clinker produces and 5206.08 tons /day of CO2 was generated. The analysis includes the design aspect for cyclone separator that has an efficiency of 42.7%.In addition, according to the feasibility study of this study it has been noticed that FCI of making plant produce 3.17 million ton/year was 4.2 million OMR. Moreover, according to the present investigation it has been identified that the solution for minimizing the emission couldn’t depend not only in method of production but also some alternative substitution for the parameters, raw material and process equipment used for production of cement.
