Md. Haque, Md. Jewel, Abdulla , Md. Rahman, Jakia — 2018-03-19

IntroductionMicrobiological contamination of aquatic ecosystem is a major issue worldwide. Human and animal fecal material is generally considered as greater risk to human health, as it is more likely to contain human enteric pathogens. These pathogens may sometimes pose serious health-hazards to the environment and human population through water and sediment.1, 2Padma is one of the largest and important rivers in Bangladesh, which flows adjacent to Rajshah city. Therefore, a huge amount of dome

India has about 61% net irrigated agricultural area playing a vital role in food security of the country.12, 46 Groundwater is one of the most used water sources for irrigation. Introduction of contemporary drilling techniques, electrical controlled pumping systems, nominal cost of electricity and groundwater legislation rules are not fully promis

A review on Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API)

L. R. Panda , R. K. Aggarwal , D.R. Bhardwaj — 2018-02-27

Introduction Due to industrialization and urbanization, air pollution has turn out to be a serious problem. Now a day’s particulate matter is the big concern due to their undesirable impact on plant and animal.1 The recognition and classification of plants into tolerant and sensitive groups is essential because the sensitive plants can use as an indicator and the tolerant as a sink for the pollutants in city and developed habitats.2 Plants have a very close relationship with nature

Mapping of Agro-Ecological Zones of North-West India in Context to Climate Change Using Geographical Information System

Mohan Singh, R.K Aggarwal — 2018-04-13

Introduction Climate is the composite of all the day-to-day weather conditions in a region over a considerable time. This time period should ideally be long enough to establish relevant statistical information necessary to describe the variations in a region.1 Climate may be thought of as an average of weather conditions over a period of time including the probability for distributions from this average.2,3 Climate is determined by three key factors the amount of energy the

Aquifer Characterization A Scientific Imperative in Analysis of Water Level Trend andndash; A Case Study from Northern Punjab, India

Gopal , M.S. , R.P. , R.P.S. , K.S. — 2018-01-18

Introduction Indo-Gangetic alluvial plains encompass thick piles of sediments characterized by regionally extensive and highly productive multi-aquifer system. Extensive groundwater withdrawal over a depth up to few hundred meters constituting the top 2-3 aquifers, mainly for irrigation means, is taking place all across this multi-aquifer system. The groundwater authority of Government of India is constantly monitoring the situation of dynamic state of these aquifers and periodically releasin

Komalpreet , Jaspal , Sarvesh — 2017-12-29

Introduction Carbon dioxide gas (CO2) available in earth’s atmosphere is about 0.04%. In change in amount of CO2 creates adverse effect on environment. CO2 emission occurs due to combustion of fossil fuels, cement production and deforestation which causes global warming. The cement production contributes large amount of global CO2 emission generated from calcinations of lime stone and combustion of fuels in a kiln. In order to control carbon dioxide emissi
