2023-09-05

The disposing of accumulated plastic trash on a daily basis is a pressing issue in management of solid waste. In India more than 34.5 lakh tonnes of plastic waste is generated, out of which plastic in the form of polypropylene is the second biggest contributor (19%) accumulating to 6.55 lakh tonnes [7], also it takes thousands of years to decompose in landfills. Fly ash, a by-product in coal-fired power units, can lead to air pollution if scattered unattended on the ground and if dumped at landfill, It would lead to toxic elements getting discharged into groundwater. More than 217.02 million tons of fly-ash was formulated of which 49.92 million tons was dumped in landfill.[12] India being a developing nation is expected to generate more than the above-mentioned plastic waste and fly ash to sustain rapid urbanization and economic growth. Hence, the purpose of this study was to look at the possibility of utilizing reprocessed polypropylene, used foundry sand and fly ash as a binding substance in the manufacturing of paver blocks. To be applied in pedestrian pathways, parking lots, gardens and less to moderate traffic volume roads. A combined method of heating and compression was implemented for full scale casting. The polypropylene pellets are melted and mixed with used foundry sand and fly ash in numerous proportions to determine the optimal proportion. Compressive strength & water absorption test was conducted on the specimen.

Nguyen Thi Ngoc Linh — 2023-09-10

Today, when the world and the market are undergoing drastic changes, digital transformation in businesses is inevitable. This process applies to both B2B and B2C, as consumer behavior, knowledge, expectations, and processes are constantly changing. A business can go digital for many reasons, but by far the main reason is that it's a matter of survival. Before the COVID-19 pandemic, an organization's ability to flexibly adapt to difficulties in supply chain disruptions, market pressures, and customer expectations was very important. The goal of business digital transformation is survival and future strength, but digital transformation initiatives have brought many other benefits to businesses. Currently, increasing customer experience has become an important and competitive factor in the business environment. Here are some reasons why increasing the customer experience is important: In a competitive market, improving the customer experience helps businesses set themselves apart from the competition. Customers often prioritize choosing the best and most memorable experiences, and this can help businesses attract and retain customers. A good experience builds trust and loyalty among customers. When customers are satisfied with a business' products, services, and experience, they are more likely to continue shopping and interacting with that business in the future. This helps to create a loyal and sustainable customer community.

Effect of video games on academic performance of university students’ assessment and appropriate solutions

Le Pham Duc Truong — 2023-09-10

Video games are inherently a useful means of relieving stress, but many people have used them negatively. Game addiction is extremely stressful. Many teenagers sit in front of a phone or computer screen all day, to the point that they forget to eat or sleep. The image of the gates of Internet shops packed with student bicycles is no longer rare. Many young people spend more time playing games than reading, studying, or participating in extracurricular activities. The cause of this situation stems directly from human consciousness. The students are still young, not aware enough of the harmful effects of the game, do not know how to manage their time, and are easily manipulated and enticed. In addition, the neglect of management by family and school is also a factor leading to the above phenomenon. In the long run, toxic video games will wreak havoc both physically and mentally. Addicts' health will deteriorate, their behavior will become sluggish, and their thinking will become clouded. Since then, students will be distracted from studying, alienated from people around them, and have severely degraded personalities. To put an end to this situation, each person must know how to adjust themselves, using games as entertainment tools in moderation.

Diwakar Singh, Dr. Yeetendra Kumar Bind — 2023-09-25

The replacement of natural resources in the manufacture of sand & aggregate is the present issue in the present construction scenario. Ground Granulated Blast furnace Slag (GGBFS) are industrial by-product materials produced from the process of manufacturing iron & recycled aggregate are material produced from waste concrete. Use of GGBFS & recycled aggregate does not only reduce the cost of construction but also helps to reduce the impact on environment by consuming the material generally considered as waste product. Hence in the current study an attempt has been made to minimize the cost of sand & aggregate with concrete mix grade M30 by studying the mechanical behaviour of this concrete mix by partial replacing with advanced mineral admixtures such as GGBFS & recycled aggregate in concrete mix.

In this study, partial replacement of sand with GGBFS & conventional aggregate with recycled aggregate respectively considered. Experimental study is conducted to evaluate the workability and strength characteristics of hardened concrete, properties of concrete have been assessed by partially replacing sand with GGBFS & conventional aggregate with recycled aggregate. The sand has been replaced by GGBFS accordingly in the range of 30%, 40% and 50% by weight of sand for M30 mix & conventional aggregate has been replaced by recycled aggregate accordingly in the range of 0% (without recycled aggregate), 20%, 40%, 60%, 80% and 100% by weight of aggregate for M30 mix. Concrete mixtures were produced, tested and compared in terms of compressive and split tensile strength.
