 Abstract

Solar energy is the most abundant source of energy available on earth. This can be used by converting it into either thermal energy or electric energy with the help of collector & photovoltaic cell. PV cell is one of the most popular renewable energy products. It can directly convert the solar radiation into electricity which can be utilized to power household appliances. However, during the operation of the PV cell, only around 15% of solar radiation is converted to electricity with the rest converted to heat. The electrical efficiency will decrease when the operating temperature of the PV module increases. In this work, we developed two different cooling techniques (one passive & one active) to maintain the temperature of PV module & compared with conventional panel under natural convection. For the active cooling, wood wool is attached at the backside of the panel. The water is provided on that after 2 hours for heat removal. For the passive cooling, honeycomb fins made up of aluminium sheet of 0.8 mm thickness are used & pressed fit at the backside of the panel with the help of plywood & nut bolts. The experimental result shows 15% improvement in electrical efficiency than the conventional panel.

The novel red-emitting phosphors of Eu3+-activated alkaline earth metal (Sr and Mg) vanadate phosphors, Na(Sr0.97-x, Mgx)VO4:Eu3+0.03 (x = 0 to 0.97) has been successfully synthesized using solid state reaction method and characterized through structure, morphology, luminescence (excitation, emission and CIE coordinates) and decay rate properties as a function of Mg ion concentration. The phosphors show an intense and broad excitation band (monitored for 5D0 ? 7F2 transition of Eu3+) in the 220- 400 nm spectral regions which make them highly suitable for GaN-based LED chips. These phosphors can be efficiently excited by near UV light and exhibit a dominant red emission at 611 nm (5D0?7F2). The decay lifetime and color coordinates were evaluated for Na(Sr,Mg)VO4:Eu3+ phosphors. Therefore, these phosphors could be a potential candidate for light emitting diodes and display applications.

 Abstract

Articulated Manipulators or Robotic Arms, as we know them, are state of the art mechatronics equipment that is at the pinnacle of the automation technologies. They have revolutionized the production processes in various industries, especially in the automobile and electronics sector. Being so advanced, they are not accessible and affordable to many, who aspire to become a robotics engineer and study robotics. The purpose of this paper is centered around the design, development and analysis (using forward kinematics) of an Arduino based 5 degrees of freedom (d.o.f) pick and place robotic arm which is manufactured using 3D Printing technology and uses servo motors. However, the development of the robotic arm itself is not sufficient unless we understand how robots are taught to do the task they are intended and developed to perform. Therefore, this paper also focuses on the various methods of Robot Teaching also known as Robot Jogging and the development of a Teach Pendant which uses potentiometers and buttons as its core components. This enables the user to teach the robotic arm to perform a required task.

 Abstract

Natural products have been used in traditional medicine for cure of many diseases. Many of the traditional drugs isolated from organisms include known anti-cancer drug taxol and antibiotics such as penicillin and streptomycin. There are large number of natural products synthesized by large array of microorganisms. However, in most of the cases the amounts of these compounds are low. Organic synthesis is aimed at total synthesis of such natural products. Such synthesis would help in large scale production and utilisation for treatment of diseases. The present review aims to analyse several newly synthesized natural products and various methods for synthesis. This would help in understanding the advancement of the total synthesis of various complex natural compounds.

 Abstract

In India as well as in West Bengal double strike came from Coronavirus and Super Cyclone Amphan, which damaged the economy tremendously. As there was no vaccine to protect the people from coronavirus so the government has taken the way of lockdown as the only instrument against the protection. But the long-lasting lockdown brought varieties of miseries in the society of which economic discomfort appeared before the day to day earning category population in huge shape. There is no direct link between COVID-19 and Cyclone Amphan but the phenomena are cognate in the sense that they are all products of the tremendous acceleration over the last 30 years, a period in which extreme forms of neo-liberal capitalism has been imposed upon the world by global elites. This great acceleration period is the acceleration of consumption and production and the resulting rise in greenhouse gas emission that lies behind all these crisis from the climate breakdown to the pandemic. Amphan the fiercest cyclone in the recent memory has left the state�s agriculture severely damaged. The loss of crops now pushed up the prices of essentials. Most of the traders in the state as well as in the country cannot reopen their business due to the lockdown. The loss incurred by the traders as well as the farmers due to the Twin factors of COVID-19 and Amphan. The Indian economy is expected to contract for the first time in nearly 41 years. If the contraction as forecasted by RBI and also by other economist is realized, it will be the first contraction for the Asia�s 3rd largest economy since 1979-80, when GDP growth shrank 5.2%. The impact of lockdown was greatly been noticed in the financial sectors. Bank deposits have risen while bank credit during the period dipped. The government is planning to keep the overall spending under check at a time when revenue flow has nearly stalled due to the lockdown, which has halted economic activities across the country. More than four months under lockdown has sent unemployment roaring and forced migrant workers to return home. In the present study an effort has been made to highlight the impact of covid-19 and Amphan on the economy of West Bengal as well as on the country India.
