Urban Air Pollution- An emerging concern

Review article of Global Journal of Energy and Environment Urban Air Pollution- An emerging concern 1Akshey Bhargava, 2Swati Bhargava, 3Prachi Gohar, 4Preeti Pandey, 5Sheetal Kamble, 6Sabina Aysha 1CEPT University, Ahmedabad, Gujarat, Rajasthan Pollution Control Board, Jaipur, India; 2Architectural Association, London and Proxemics Studio London; 3MS Environmental sciences, Brunel university, U.K; 4Msc./M Tech Environmental Engineering; 5Ph.D Environmental science, Assistant Professor, P.P. Savani University, Surat; 6.Senior Environmental chemist at Qatar Geotechnical and Environment Company(QGEC) in Doha , Qatar Air pollution in cities and urban sectors are increasing significantly on a time scale at global level. This alarming fact is substantiated with its gravity in the sense that more than 80% of people living in urban areas are exposed to air quality levels that exceed the World Health Organization (WHO) limits. The situation world over is more critical to populations in low - income cities which are most impacted. According to the urban air quality database, 98% of cities in low - and middle income countries with more than 100 000 inhabitants do not meet WHO air quality guidelines. However, the cities in high - income countries this percentage decreases to 56%. The WHO reveals the fact that around 3000 cities in 103 countries have started measuring air pollution levels and recognizing the associated health impacts. With declines of urban air quality, the risk of stroke, heart disease, lung cancer, chronic and acute respiratory diseases, including asthma, increases for the people who live in these cities. An effort has therefore been made by the authors in this paper to explain briefly some of the relevant factors responsible for urban air pollution such as heat island effect, albedo effect, urban planning with environmental inputs, climate change, urban environment policy parameters, sustainable urban transport, environmental sustainability etc. These issues need to be addressed globally on ...

Hybrid Voltage Multiplier for RF Energy Harvesting Circuits

Research article of Global Journal of Energy and Environment Hybrid Voltage Multiplier for RF Energy Harvesting Circuits Fredrick Isingo, Prosper Mafole, Abdi T Abdalla Department of Electronics & Telecommunications Engineering, Collage of Information & Communication Technologies, University of Dar es Salaam, Dar es Salaam, Tanzania Paper describes the design of an improved voltage multiplier for Radio Frequency (RF) energy harvesting circuits using a generic doubler circuit and the Dickson’s charge pump, all these utilize the BAT63-02V Schottky diode. The design is based on using four narrow band antennas operating at 800MHz, 1800MHz 2100MHz and 2400MHz, the designs and simulations are performed by Keysight’s ADS 2019 simulation software, the outputs observed show improved voltage levels that can be used to operate ultra-low powered devices such as sensor nodes and remotes. Keywords: RF energy harvesting, Schottky Diode, Voltage multipliers ...

Environmental Pollution- An Introduction

Review article of Global Journal of Energy and Environment Environmental Pollution- An Introduction 1Dr. Akshey Bhargava, 2Prablin Kaur, 3Sabina Aysha, 4Preeti Pandey, 5Prachi Golhar, 6Palavi M Vishwanath 1 Ex. Professor, CEPT University, 2Assistant Professor, P. P. Savani University, Surat , 3 Senior Environmental chemist at Qatar Geotechnical and Environment Company(QGEC) in Doha , Qatar, 4 Msc/M.E Environmental engineering,5 MS Environmental sciences, Brunel University, U.K,  6Assistant Professor at Sir M V School of Architecture, Bengaluru, Karnataka, India Pollution is defined as introduction of harmful components into the environment and those harmful components are called pollutants. They can be natural, for example, volcanic ash, decomposition of organisms etc. or can also be created by human activity, such as dumping of waste, effluent produced by factories or emissions generated from factories, vehicles etc. They can damage the quality of air, water, and land.Many things that are useful to people produce pollution like burning coal to production of electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides—chemical poisons used to kill weeds and insects—seep into waterways and harm wildlife.Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use. An effort has been made by the authors of the present paper to briefly highlight environmental pollution and its emergence.

Experimental Study on Natural and Force Convection Hybrid Active Greenhouse Solar Drying of Mushroom

Research article of Global Journal of Energy and Environment Experimental Study on Natural and Force Convection Hybrid Active Greenhouse Solar Drying of Mushroom Anand Kushwah*, M.K.Gaur , Puspendra Singh, Vikas Thakur Mechanical Engineering Department, Madhav Institute of Technology and Science, Gwalior, (M.P.) This manuscript deals with drying of food to avoid losses between accumulation and consumption of edible material (food), as higher moisture content is one of the reasons for its spoilage during the storage period at time of accumulation (harvesting) .High moisture content in crops leads to fungus infection, attacked by insects, pests and the increased respiration of agriculture produce, which further all threat to food productivity and food security. In order to ensure this concern Solar drying of Mushroom is conducted to investigate the performance of the hybrid active greenhouse for drying mushroom and also study the drying behavior of mushroom (Pleurotus Florida) in terms of its convective heat transfer coefficient and moisture removing rate (% db). The green house consists of a transparent UV stabilized plastic covered and wire & tube type heat exchanger and drying chamber unit. Various experiments are conducted during the course of winter season, in months November and December 2017 and also January 2018 at Madhav Institute of Technology and Science, Gwalior campus (26ᵒ.2183N and 78ᵒ.1828E), India. Experimental set up is situated on the open floor to have a good exposure to the solar radiation. Experimental data are used to calculate the Nusselt number constants using linear regression method. The products (mushroom) to be dried are placed on a single layer wire mesh in the drying chamber to receive energy from hot water obtained from the evacuated tube solar collector (ETSC) and the incident solar radiation on products. During the experimental procedure minimum and maximum solar radiations are 243 W/m² and 925 W/m² ...
