A Short Glimpse on Eco-friendly Cement: A path towards Sustainable Construction

Soumya Mukherjee — Thu, 30 Nov 2023 00:00:00 +0530

Cement is the main construction material for the development of infrastructure. At the same time, cement industries play a main role in the deterioration of the environment, by emitting carbon dioxide and other obnoxious gaseous emissions. Green cement production encompasses a holistic approach to sustainability, focusing on reducing carbon emissions, optimizing resource utilization, promoting energy efficiency and fostering environmentally responsible practices. There is a need to start implementing green cement to reduce carbon emissions and preserve our planet for future generations.

An Investigation to Optimize Casting Process Parameters – A Simulation Approach

Manas Karak, Arijit Dutta — Thu, 30 Nov 2023 00:00:00 +0530

In casting using experimental method to visualise mould filling and solidification is difficult. To control and monitor casting quality, simulation is desirable. Effects of different casting process parameters in solidification time are observed in this project. In this project, casting process design and simulation are done using ProCAST (Demo version) software. Boundary and initial conditions were reasonably set. Impact of different process parameters on solidification time is analysed. ANOVA is used to find the relation between input and output parameters and a regression equation is made for prediction.

A New Nonlinear One-Dimensional Shape Function applied to Simulate a Steady State Heat Transfer Problem

Arup Kumar Biswas, Samir Chakravarti, Santanu Das — Thu, 30 Nov 2023 00:00:00 +0530

Generally linear shape functions are considered for two noded elements as coefficients of higher order polynomial cannot be determined from two nodes. In the present work, attempts have been made to fit a non-linear trigonometric shape function for one dimensional two noded elements. As in case of nonlinearity, the dependent variable varies nonlinearly with the independent one, consideration of linear shape function may lead to erroneous results. Here, a one dimensional heat transfer problem is solved analytically, with the help of linear shape functions and with the help of newly developed nonlinear shape functions. Analysis shows that results obtained by considering nonlinear shape functions have quite good match with that by linear shape functions.

Water and Environment of Kangsabati River

Gautam Kumar Das — Thu, 30 Nov 2023 00:00:00 +0530

The normal flow of the Kangsabati River, famous for its reservoir at Mukutmanipur, has been practically stopped due to damming on a temporary basis particularly in middle and downstream stretches. Although there are no significant towns on the riverbanks, water is polluted by mixing of waste materials in the river water from the non-point sources. The pollution level of this river is determined in the category of priority IV for BOD concentration 6.4 mg/l of the surface water samples near Midnapore town.

GLOFs Disasters in Himalayas: A Defeat against Climate Change

Sandeep Nandi — Thu, 30 Nov 2023 00:00:00 +0530

In the fight against climate change, India had to face two crushing defeats in the form of environment disasters, the Glacial Lake Outburst Floods (GLOFs) in the Himalayas, in 2013 in Kedarnath and in 2023 in Sikkim. In the last 4 decades, the focus regarding global warming was on Ozone hole and polar ice caps which as per forecast, would melt, and cause sea levels to rise worldwide. No one had predicted the GLOFs disasters due to climate change. The above events call for monitoring and risk assessment of pro-glacial lakes in the Himalayan region to prevent any more disasters.

Impact of Climate Change - Evidence from Archaeological Structures of West Bengal

Gautam Kumar Das — Thu, 30 Nov 2023 00:00:00 +0530

The weathered and battered ancient archaeological structures are vulnerable to climate change. Due to global warming, climate change, sea level rise, etc., construction and cementing materials of the archaeological structures are undergoing rapid, adverse chemical changes. As a consequence, construction materials are losing their durability and the adhesive power of indigenous cementing materials used in ancient structures are rapidly diminished. The current status of construction and cementing materials at various archaeological sites across the Bengal basin and the impact of climate change on them are discussed.

A Comparative Study of the Number of Existing Water Bodies in and around Sunderbans

Nilabhra Rohan Das — Mon, 07 Oct 2024 00:00:00 +0530

West Bengal ranks first among the Indian states regarding the existing number of water bodies. Among the districts, South 24 Parganas houses the highest number of water bodies. The majority of South 24 Parganas district is part of the Sunderbans delta region. Objective of this study is to compare number of enumerated water bodies, at the country, state and district levels as well as an analysis of districts in West Bengal with the highest number of water bodies recorded. The analysis reveals that there is a big gap between total number of water bodies in existence in South 24 Parganas and the runner up districts. Another motif of this study is to find appropriate causes behind.
