Abstract: The presence of gas stations in residential areas is very dangerous for what can happen in case of accidents, fires, fuel leaks from tanks or even among vehicles when filling, refueling, in addition to the risk of toxic gases due to lead in gasoline. The article evaluates disaster management in the operational reality of gas stations in urban areas. It also analyzes the reality of occupational diseases and accidents at work of employees in those infrastructures. On this basis, appropriate recommendations and proposals are put forward to serve in the drafting of legislation regulating the distribution of hydrocarbon fuel and disaster management.

Abstract: Noise pollution is addressed as a public health issue induced mainly by urbanization. It is a growing problem in developing cities like Mymensingh, the second-most densely populated city in Bangladesh. Noises of this city are primarily generated from different sources like mass gatherings, transport Vehicles, loudspeakers, Public address systems, festivals etc. The study was conducted at 26 locations, including commercial, sensitive, residential & mixed areas, to analyze the different noise levels from March 6, 2021 to March 14, 2021. GIS (ArcGIS 10.8) with IDW technic was used for detailed noise pollution mapping of the city. Recorded data were compared with Bangladesh Noise Standard (DoE 2006), WHO (2009) and US(EPA) standards. The obtained spatial analytic maps showed......

Abstract: This research attempt to explore the geospatial technology to Model the patiotemporal pattern and the impact of the normalised Build-up index (NDBI), the L S T and NDVI, and how it influences the land use/ land cover (LU/LC) of the region under study. The project depicts the dynamics of urban heat island (UHI) and how they impact the (LU/LC) for 4 epochs (2004 to 2019). We have also detected and identify the dynamics variation in land cover changes that occurred during 15 years leveragingboth open/license source software such as R and GEE, ArcGIS 10.6, Envi 5.3 and. The multi-temporal Landsat satellites images (ETM, and ETM+) covering the Mubi region 2004, 2009, 2014 and 2019 were used as the primary data sources for this project. The global mapper 19 software, Google Earth Pro, https://earthexplorer.usgs.gov/ & http://glovis.usgs.gov, were used for image acquisition while the ArcGIS 10.6, Erdas Imagine 2015 and R software were used in the data analysis. From the analysis, the urban......

Abstract: Though carbon dioxide is crucial for life on earth, its extensive release causes a lot of problems like global warming and greenhouse effect. To avoid this, its release into the environment needs to be controlled. Besides this, carbon dioxide has many industrial uses. Hence the process of carbon dioxide scrubbing was brought into picture, in which the carbon dioxide present in the flue gases is scrubbed with the help of liquid solvents. Aqueous amine solvents are commonly used for this process, with primary and secondary amines as the most common choice among the industries. However, due to the large regeneration energy requirements, studies are being carried out on the use of tertiary amines and sterically hindered amines for this process. This work focuses on these solvents, with their merits and demerits, related to the process. From the comparison carried out in this work, it can be seen that the tertiary amines, blended with activators, prove to be a better choice with respect to energy requirements than the pure primary amines.

Abstract: This paper gave a theoretical understanding of the transmission of symmetrical structure of InGaAs/GaAsSb double quantum well in InP substrate using transfer matrix method (TMM). Variation of the barrier width at a fixed proportion of the Indium concentration in InGaAs/GaAsSb which denotes the conduction band offset was studied with respect to the intensity of transmission reveals that the energy eigenvalues of the quantum well increases with increase in the width of the well with the least energy value obtained at the highest well width. The position peak shifts to the lower energy when the width of the well is increased, with value of 0.0381 eV to 0.0134 eV for well width of 10 nm to 20 nm respectively. With the effect of the electric field of about 0.1 eV, there was an improvement in thr transmittance of the heterstructure from 0.9073 to 0.9882 for well width from 10nm to 20 nm respectively. Effect of the energy on transmission coefficients considering tunneling effects were shown using the Matlab program to evaluate Transfer Matrix Method.

Abstract: Various current movements in urban design seek to create sustainable urban environments with long-lasting structures and a great livability for its inhabitants. Where the cities were designed and developed without urban design principles like in Abuja, Nigeria, urbanization occurs. While the roots of urban development problems in Nigeria are traceable to approaches to social and economic development of the country dating back to events before the pre-colonial era, national socio-economic crisis has fundamentally shaped the country's approach to development since Independence in 1960. In Abuja, urban development laws were prepared such that land use, infrastructure, housing,.......
