Size miniaturization of microstrip patch antenna
In this paper, we discuss size miniaturization of microstrip patch antenna using the miniaturization techniques because the compact wireless devices have been in uses and there a need to reduce the size of microstrip patch antenna. This micro strip patch antenna has been designed and simulated using HFSS (High-frequency structure simulation software) tool and getting the good frequency and VSWR results within the UWB frequency range 3.1 to 10.6 GHz. Modified MPA by etching step slot in the ground plane and etching the polygon slot in patch plane.

Social media and its impacts on politics
In recent years, social media are said to have an impact on the public discourse and communication in the society. The Internet has become an increasingly important tool for citizens to not only gain political knowledge but to engage in the political process itself. In particular, social media are increasingly used in political context. More recently, micro-blogging services (e.g., Twitter) and social network sites (e.g., Facebook) are believed to have the potential for increasing political participation. While Twitter is an ideal platform for users to spread not only information in general but also political opinions publicly through their networks, political institutions have also begun to use Facebook pages or groups for the purpose of entering into direct dialogs with citizens and encouraging more political discussions. In this paper, our main focus is to discuss the influence of social media on politics. We explained the importance of social media from the perspective of voters and politicians. We also focused on positive and negative effects of social media on politics. Finally, we conducted an online survey through questionnaires to know the impact of social media on politics.

Experimental study on concrete by replacing cement and aggregate with ground granulated blast furnace slag and crump rubber
Concrete is most widely used building material in the world, as well as the largest user of natural resources with annual consumption of 12.6 billion tons. Concrete is a mixture of cement, fine aggregate, coarse aggregate, and water. Concrete plays a vital role in the development of infrastructure which is, buildings, industrial structures, bridges, and highways etc. Recycled rubber tyre waste is a promising material in the construction industry and the sole reason for this is the lightweight of the resulting concrete when the rubber tyre is incorporated in it as an aggregate replacement.One another such material is Ground Granulated Blast Slag (GGBS). Ground Granulated Blast furnace Slag (GGBS) is a by-product of the blast furnaces used to make iron. GGBS is used to make durable concrete structures in combination with ordinary Portland cement and/or other pozzolanic materials. GGBS has been widely used in Europe, and increasingly in the United States and in Asia for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years

Incremental dynamic analysis and static pushover analysis of existing RC framed buildings using the seismostruct software
Civil Engineering structures are designed to withstand environmental forces like an earthquake, along with gravity loads. These forces are random and dynamic in nature. Therefore the response of the structure is also dynamic and that is what causes the unsafe and uncomfortable conditions. So, performance-based analysis of the structure is required which can be achieved by Incremental Dynamic Analysis (IDA) as well as static pushover analysis (SPA). But, the incremental dynamic analysis is quite accurate and actual response of the structure of the structure from the particularly considered earthquake can be obtained by this method. It involves performing a series of nonlinear dynamic analyses in which the intensity of the ground motion selected for the collapse investigation is incrementally increased until the global collapse capacity of the structure is reached. In the present work, incremental dynamic analysis of reinforced concrete G+6 and the G+11 building is carried out. IDA curves are developed with respect to peak ground acceleration. Performance stages of the buildings such as yielding and collapse are defined with respect to peak ground acceleration of the considered earthquake from the IDA curve. Building susceptibility that is whether the building can sustain the particularly considered earthquake or not is found out using IDA. Also, serviceability criterion for inter-story drift ratio from IS 1893:2002 is checked from the IDA. Static pushover analysis of both the G+6 and G+11 building is also carried out. From the static pushover analysis, the graph of base shear to top displacement is plotted. From the graph, the base shear capacity of the building is found out. The base shear capacity of both the buildings is also found out using IDA and capacity curve of base shear to top displacement from IDA is compared with that of SPA.

Safety analysis in construction worksite using fuzzy AHP and fuzzy TOPSIS
Safety on construction sites is a complex issue. A safety management system (SMS) aims to decrease the number of accidents, injuries, and health problems among workers at a workplace. Ensuring safe workplace conditions at construction sites depends on different factors, including safety rules, management commitment, safety training, and safe behaviour. The current research aims to establish a method for identifying and evaluating the factors that impact workplace safety conditions at construction sites. The fuzzy analytical hierarchy process (AHP) technique was used to determine and measure the qualitative factor weights affecting workplace safety to assist in the evaluation of multiple concurrent criteria. Hence, the fuzzy AHP technique was used to determine criterion weight. Alternatively, a fuzzy technique for Order Performance by Similarity to Ideal Solution (TOPSIS) model was used to evaluate the performance of companies and rank them according to their safety performance. Based on the results and findings of the presented approaches, four companies were ranked for their overall safety performance. The findings are encouraging and can be used in the construction industry to benchmark the performance of con¬struction companies for their application of safety rules and regulations. The approach also determines the leading companies in terms of best practices and provides information for government inspectors to investigate the priorities identified for inspection.

Experimental study of construction and demolition waste in flexible pavement
With the steep increase in the population, construction and demolition of buildings around the world have increased at the same pace which has led to the accumulation of C&D waste. Their disposal is one the major problems as the huge amount of land is required for landfill. In this research possible use of C&D wastes in semi-dense bitumen, macadam has been studied, so these C&D waste can be disposed of properly furthermore the natural aggregate which is depleting at very fast rate can be saved for the future generation. In this study test are conducted to check the feasibility of C&D waste in the asphalt pavement .various tests such a marshal stability test, tensile strength test is conducted to determine the optimum percentage of construction and demolition waste which can be used in semi-dense bitumen macadam. It also helps in saving the material for future. That can be used for bigger construction. The demolition waste with the different percentages as a coarse aggregate has been used in this research and the results have been compared with the conventional mixes. Over 90% of demolition wastes can be filled with the land fillings and due to its toxic nature it will affect the soil and make it useless. Marshal stability and indirect tensile strength tests have been performed which resulted in the increase in the durability and strength of payments.
