 Abstract

This review research paper examines the evolution of the microstrip patch antenna (MPA) in the field of wireless communication technology. Distinguished researchers have made several efforts to develop MPA in order to meet market demands. To begin, this paper provides a quick overview of wireless technology and MPA. Following that, a literature review is provided in order to better comprehend the concept of a patch antenna that is small in size, has multiband and wideband functionalities, and is widely used in wireless communication. Reported antennas simulation have been accomplished with the help of CST, HFSS, and other tools. Return loss, VSWR, directivity, gain, efficiency, and radiation pattern are all examined with this software. The end result of numerous investigations has been mentioned which can be primarily based on antenna performance factors like patch slot, antenna dimensions, substrate material, and feeding techniques. For their better understanding these findings delineated within the tabular form and finally conclusion of the overview paper is discussed.

 Abstract

Migration is a way to move from one place to another in order to live and work .In economy sector the most valuable commodity is human resource, whether organised or unorganised. work satisfaction is the feelings, behaviours or desire about work and culture of an individual.This study aims to learn more about the migrant workers' employment satisfaction in Tirupur City. This research intends to study essential problems encountered by migration workers and suggest some ways by which they can be adequately and efficiently financed.

 Abstract

India has rich biodiversity and harbour a wealth of various natural flower resources and there is no doubt that the plant kingdom is a treasure house of diverse nature products. Plants, insects and minerals are the sources for obtained the natural dyes. Plants are the most important sources and it can be obtain from various parts includes stem, leaves, flower, fruits, seeds and pills are utilize to extract the natural colorants. Flower dyestuff/colorants are important in textile dyeing as it provides dyes from the sources which is available abundantly but still not fully utilized. This study attempt to review some floral natural dyes and its application on textile sectors.

 Abstract

महावीर प्रसाद द्विवेदी के दौर में भारत की दुर्दशा चरम पर थी। भारत उस समय बाह्य और भीतरी गुलामी से घिरा था। बाह्य गुलामी थी औपनिवेशिक शासन यानी अंग्रेजों की और भीतरी थी परम्परा, जातीयता और वर्गीय गुलामी की। जब समाज में इस तरह की कुरीतियाँ हो तो समाज की स्त्रियों के साथ न्याय कैसे हो सकता था। गुलामी की यह मानसिकता स्त्रियों के सन्दर्भ में भी रही। सदियों से स्त्रियों को माता व पत्नी के कर्तव्यों में जकड़ कर रखा गया। उनकी अभिव्यक्ति को आवाज़ देने वाला कोई न था और न उनमें खुद अपनी स्थिति को समझने की चेतना थी।

 Abstract

Businesses the around the globe are now concerned with risk as much as they care about profitability. Importer and exporters are exposed to loss arising out of exchange rate fluctuations. One of the important approaches to quantify risk is by estimating the Value at Risk (VaR). VaR is the maximum loss that can occur over a certain period of time. This paper estimated the VaR for exporters and importers using the Simulation models, GARCH (1,1) model and variance based model. Based on the results of Back testing it was found that Historical simulation model among these models provides the best estimates and it is therefore recommended for use by exporters and importers in India.

 Abstract

Fresh water supply is one of the most limiting conditions for the population of arid regions. The present paper covers the working principle of systems and processes for extracting water from atmospheric air. Moreover, a summary of the experimental and analytical studies which investigate system performance has been made. Some new designs that greatly expand the solar desiccant technique for absorption with subsequent regeneration are also introduced. The research activities in this sector are still increasing to solve the crucial points that make these systems not yet ready to compete with other systems as water distillation.

 Abstract

Plants have evolved a variety of plant structures and cell walls with mechanical qualities that are crucial to the economy as a result of their responses to biotic and abiotic challenges. Bio acoustic methods have been used to monitor plant health, photosynthesis, ecology, and the quality of marketable plant products, as well as to quantify the mechanical properties of plant structures, improve mechanical harvesting, and identify the distribution of root systems. The circuit created as part of this research effort was used to produce acoustic music using the plants. With the aid of the 555 Timer IC, pulses were produced from discrete analogue signals, and these pulses were then processed to create acoustic music. Along with the light display on the circuit, waveforms were also produced in real time using Serial Plotter in the Arduino IDE programme. The life of plants is extraordinary. In order to communicate with other creatures, which was previously impossible, they needed a medium. This paper describes the development of a tiny step toward plant communication using Plant Bio Acoustics.
