A Commentary on the Applications of Python in Resolving Issues Concerning Energy and the Ecosystems
Full text linkThe energy industry is just getting started with applying it to problems with energy and ecosystems so they can find solutions. Python\u27s popularity has increased across a variety of sectors, including businesses, academic institutions, government agencies, and research organizations. The true potential it possesses to automate a variety of processes while simultaneously increasing the capabilities of various industries to predict outcomes has been observed. Because of the digital transformation, such as sensors and high-performance computing services, which enable artificial intelligence (AI), machine learning (ML), big data acquisition, and storage in digital oilfields, its popularity has been on the rise in the industry that deals with energy and ecosystems. This is one of the primary reasons why. This can be easily verified by conducting a quick search for the number of publications that have been produced in the field of energy and ecosystems by the Society of Petroleum Engineers over the past few years. Without having to invest in pricey software, the production and reservoir engineers will be able to better manage the production operation thanks to this development. In addition to this, it will lead to a decrease in the overall operating costs and an increase in revenue. As a result, it has been demonstrated to be a promising application that has the potential to bring about a revolutionary change in the industry of energy and ecosystems and to transform the features that are already in place for the purpose of resolving issues related to energy and ecosystems
A Parametric Study Of Window, Orientation And Shading to Minimize Energy Consuption in Mechanically Ventilated High Rise Office Buildings in Dhaka, Bangladesh
Full text linkVital statistics of a building, meaning geometric attributes, are very important design tool to manipulate energy performance of a building which is often neglected. Though a lot of recent researches focused on increasing capabilities of material and technology to build energy efficient buildings, design elements such as form, shape, window, orientation, etc. can play a very important and effective role to increase energy efficiency. The strategic design decisions about geometric attributes in the design phase costs almost nothing and can save energy bills through lifetime of the building, which is yet be specified in particular climatic region and particular building types where energy consumption matters in national scale. This paper investigates the critical proportion of façade glazing through parametric study by simulation to obtain optimum balance between luminous and thermal behavior as well as energy consumption. The context of the study is Dhaka, with tropical monsoon climate where heat and humidity is a big concern. The experiment is carried out and hence relevant to highrise office building due to its large vertical surface compared to insignificant roof area. The outcomes indicate that significant harvesting of daylight and reduction of total energy consumption by 50% comes with proper shading on large glazing on East and West facade; and 30% on South facade.
 
Performance Evaluation of Multiple Helical Tubes as a Receiver for Solar Parabolic Trough Collector
Full text linkSolar parabolic trough collector consists of a parabolic reflector with a central receiver at a focal point through which heat transfer fluid is passed. Parabolic trough collector is used mostly in solar thermal power plants for generating electricity. This paper describes the experimental results of two straight tubes wrapped over each other to form a helically shaped receiver. The receiver was tested with aluminium material with and without black paint over it. Also, the helical tube receiver was tested with a glass cover over it, at two different mass flow rates and, with and without manual tracking. The tested instantaneous thermal efficiency ranges from 31.26% to 45.28% and the overall thermal efficiency ranges from 14.9% to 31.41% during the experimental period. The instantaneous thermal efficiency increased by an average of 1.32 times for unpainted receiver and 1.36 times for black painted receiver with the increase in mass flow rate. By tracking the parabolic collector according to sun’s position, there is an average increase in instantaneous thermal efficiency by 1.1 times for unpainted receiver and 1.04 times for black painted receiver. The paper further reveals that the use of multiple helical tubes as a receiver for parabolic trough collector increases the overall efficiency of the collector in a substantial manner

Azolla (Caroliniana): An Aquatic Energy Crop for Remediation of Eutrophic Ecosystems with Prospect of Biofuel Production in Bangladesh
Full text linkThe Phytoremediation ability of aquatic macrophyte, Azolla as potential biomass, to improve the quality of eutrophic lakes and river water of Bangladesh at lab scale were studied to remove organics, solutes and improving the physicochemical properties of water including pH, DO, EC, TDS, Turbidity and NaCl concentration. In the different eutrophic water, a 100% survival rate of the species was observed. The extensive root system of the phytoremediator improves water quality after one week as determined by a marked decrease in Turbidity, TDS, EC & Nacl and increased in DO and pH. DO content served as a useful indicator of water quality and increased manifolds over 7 days (one week) of treatment. The capability of the plant in removing pollutants and improving water quality was established from the study. After phytoremediation activities, the discarded energy crop biomass could be used to produce green energy because of its high growth potential.
 
A Case Study Of The Environmental Impact Assessment Legislations In Sarawak, Malaysia
Full text linkEnvironmental Impact Assessment (EIA) is a planning tool used to identify, predict, evaluate and mitigate the environmental effects of development projects. In Sarawak, EIA is governed by the both the State and the Federal EIA Orders. This leads to ambivalence in determining the legislation under which a prescribed activity demanding an EIA falls. This case study aims to investigate the implications associated with the coexistence of both EIA Orders in the state of Sarawak from the viewpoints of practicing environmental consultants. The case study reviews the EIA legislations governing EIA practices in the State and includes a qualitative survey involving practicing EIA consultants to gather feedback on the implications associated with the EIA practices and recommendations to resolve the problems identified. The study shows that even though a prescribed activity is defined by the EIA legislations, different stages of the prescribed activity eventually become prescribed activities on their own, which demand fulfillment of different EIA legislation. Unclear demarcation of EIA jurisdiction and different requirements on the scope of an EIA particularly for earthworks also contribute to doubts among environmental consultants interviewed. Consultation, involvement and effective communication with environmental protection as priority are crucial to minimize any uncertainty resulted from co-implementation of both the EIA legislations. Future study can look into comparing perceptions on the effectiveness of the State and the Federal EIA legislations. The case study delves into a crucial issue related to EIA practices in Sarawak, Malaysia which has persisted without being formally addressed in any previous studies.
