Unraveling the Dynamics of BRICS: A Comprehensive Analysis of CO2 Emissions, Energy Consumption, and Technological Innovation
Get PDFWith rising worldwide concerns about climate change and environmental sustainability, it is crucial to understand the link between energy usage, technological innovation, and CO2 emissions. Therefore, this study examines the complex link between energy consumption, technological innovation, and CO2 emissions in the BRICS economies over the time period from 1990 to 2022. To understand the BRICS dynamics and environmental sustainability, the Panel Mean Group Autoregressive Distributed Lag (PMG-ARDL) model is used. The results indicate a significant positive relationship between energy consumption and CO2 emissions, implying that BRICS economies experience a rise in CO2 output due to increased energy usage. Simultaneously, the research reveals an inverse connection between technological innovation and CO2 emissions. In this regard, technological advances are crucial for sustainable growth and environmental protection in the region. This research provides useful insights into the intricate interaction of factors that influence CO2 emissions in developing nations

The Implementation of Solar-Wind Cascading Power Station in Bangladesh
Get PDFEnergy insufficiency is disturbing the improvement of Bangladesh. Since the sun light is not available always and the breeze does not blow constantly, solar and wind power alone are weaker power sources. Coupling solar as well as wind power sources along with storage batteries making up the full duration of time in the absence of wind or sun light supplies a pragmatic shape of power generation. In Bangladesh, breeze is not available most of the places. Only in the coastal areas, wind is sufficient to produce electricity. However, sunlight is available all over the year here. Although solar and wind alone power station has installed here but solar-wind cascading power station has not been installed yet
Flexural Performance of Concrete Structures Reinforced with Fiber Reinforced Polymer (FRP)
Get PDFOne of the most recent uses of FRP is to replace the use of steel in reinforced concrete structures. There are multiple reasons for deciding to choose FRP instead of steel such as their lightweight which can be quite beneficial to the design of buildings, high strength, and high flexibility. However, the initial use of this material was anticipated in the retrofitting of heritage buildings or any other damaged structures. There are several studies that concentrated on the use of FRP to enhance shear and flexural strength of concrete structures. However, limited studies concentrated on the effect of FRP on flexural behavior of concrete beams. Therefore, the aim of this research is to investigate the flexural performance of concrete beams that are reinforced using fiber reinforced polymers. The experimental program that was conducted in this study was divided into 4 different beams, 2 of them were reinforced using ordinary steel, while the other 2 were reinforced using carbon fiber reinforced polymer (CFRP). The highest potential deflection occurred in steel beam was 4.2 mm after applying a maximum of 42 MPa. The second beam was reinforced with FRP and accomplished 38.06 MPa, and the resulted deflection was around 12mm. The third beam was reinforced with steel and highest flexural strength measured was 75.56 MPa, while the deflection resulted from this load is 5.52 mm. Finally, the last beam was reinforced using FRP rebar and resulted deflection was 11.11 from 60.84 MPa. This study has showed the potential of using FRP in concrete structures especially in terms of flexural performance. Further studies are needed to investigate the influence of water and chemical substances on the performance of concrete beams reinforced with FRP
Environmental Impacts of Real Estate Project at Pallabi Eastern Housing Area in Dhaka City, Bangladesh
Get PDFDhaka is the capital city of Bangladesh. Many people are migrating day by day. For their survival, the housing sector is being flourished day by day. The demand impacts the supplies. A number of people are doing housing business to support the situation, but on the contrary, they are grabbing a lot of green fields or water bodies from private properties and evacuating the owners. One of the ill examples is the Eastern Housing Pallabi 2nd Phase Project. The study aims to find the socio-economic status of the land owners and local inhabitants evicted from their land for the project. Concurring to the essential perception and data collected from diverse sources, roughly 350 families are migrated. Of The 45 relocated people placed under survey from the questionnaire survey by snowball sampling, it was found that most people were discovered to have been physically relocated from their original location. The income level, housing situation, and utility infrastructure are poorer than before the resettlement. They are too unaware of taking action against the developer for the deprivation in the land price. The research revealed various facets that shed light on how land developers abused the local population. Land developers, local oligarchs, local politicians, and locals were the four characters who actively participated in this relocation process and played various roles. A few scopes are identified to rehabilitate the victims to recover from their present situation. Government should adequately care about the reallocated people to compensate at the present rate considering the long period of suffering. There is scope for more intensive study on the topic
Urban Population Growth, Per Capita Energy Use, and CO2 Emissions: Evidence from the World\u27s fifth-most Populous Country
Get PDFPakistan is the world’s 5th most populated country. This growing population is causing numerous social and environmental problems. By the increase in population, energy demand is increasing day by day. Pakistan, where majority of the population is living in rural areas is using uncleaned cooking fuel due to which CO2 emission is increasing that is further a cause of environmental degradation. Based on the data (for the period from 1980 to 2019) of World Development Indicators, this study intends to examine the association between urban population, and energy use with CO2 emission. Unit root test was applied to check stationarity of data and after checking the stationarity status of variables, ARDL (Auto regressive distributive lag model) techniques was applied on data. The outcomes of the study showed that trade openness, urbanization, and energy consumption have significant and positive effects on environmental degradation. This study suggest that government must plan population and take steps towards the use of clean cooking fuels to control environmental degradation
