MSWM encompasses a range of interdisciplinary measures that govern the various stages involved in managing unwanted or non-utilizable solid materials, commonly known as rubbish, trash, junk, refuse, and garbage. These stages include generation, storage, collection, recycling, transportation, handling, disposal, and monitoring. The waste materials mentioned in this context exhibit a wide range of items, such as organic waste from food and vegetables, paper, plastic, polyethylene, iron, tin cans, deceased animals, byproducts from demolition activities, manure, and various other discarded materials. This study aims to provide insights into the possibilities of enhancing solid waste management in the Farmgate area of Dhaka North City Corporation (DNCC). To accomplish this objective, the research examines the conventional waste management methods employed in this area. It conducts extensive field surveys, collecting valuable data through interviews with local residents and key individuals involved in waste management, such as waste collectors, dealers, intermediate dealers, recyclers, and shopkeepers. The results indicate that significant amounts of distinct waste categories are produced daily. These include food and vegetable waste, which amount to 52.1 tons/day;polythene and plastic, which total 4.5 tons/day;metal and tin-can waste, which amounts to 1.4 tons/day;and paper waste, which totals 5.9 tons/day. This study highlights the significance of promoting environmental consciousness to effectively shape the attitudes of urban residents toward waste disposal and management. It emphasizes the need for collaboration between authorities and researchers to improve the current waste management system.展开更多

Furthermore, we examine the serious implications these risks have on corporate security. Of particular concern, parents who work with confidential corporate information, such as financial projections or product roadmaps, might find that their kids are targeted by hackers who seek an easier entry-point to home networks and eventually WFH devices. This paper is timely since there is a rising trend of hybrid work in white-collar professions, mixing traditional in-office work with WFH. The latter is increasingly done in split shifts, including work performed before breakfast or after dinner. While this shift offers numerous workforce advantages and helps teen-parent bonding, it also introduces a plethora of cybersecurity risks, especially when these devices and networks are shared with teenagers on home networks. We did a structured survey of 62 teens which confirms that risky online activity abounds, so the threat of risk migration onto corporate networks should not be ignored. We perform a migration risk assessment and identify which teen-origin risks are most likely to contaminate parents’ WFH devices. We evaluate 20 attack vectors and generate 60 risk ratings. We classify 29 as high risk, 8 as medium risk, 13 as low risk, and 10 as not relevant. We offer recommendations to mitigate this new set of cyber risks.展开更多

However, it is difficult to confirm, calculate and check the costs and benefits brought by the implementation of corporate social responsibility under the current ac- counting theory system, so it is difficult to estimate whether the fulfillment of corpo- rate social responsibility has any effects on the corporation value assessment. Therefore, based on corporate social responsibility, the correction mode of corpora- tion value assessment is put forward.展开更多

Using the scenario-based analysis method, this paper analyzes how the output and emission related properties, including cetane number, and sulfur and aromatics contents of diesel produced by CNPC, will vary with changes in the configuration of diesel production units in the next 5-10 years. The results showed that, to upgrade its diesel, CNPC needs to adjust its diesel pool by decreasing the share of fluid catalytic cracking (FCC) diesel and increasing the shares of hydrocracking (HDC) and hydrotreating (HDT) diesel. Furthermore, to produce ultra-low-sulfur diesel, straight-run diesel as well as poor diesel blendstocks such as FCC diesel and coker diesel should be hydrotreated before being blended into finished diesel. Developing highly efficient HDC and HDT catalysts and corresponding processes is the key to CNPC economically producing more and cleaner diesel.展开更多

(CNPC), the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the emission related properties, including antiknock index, and sulfur, olefin, benzene and aromatics contents of gasoline produced by CNPC, vary with the change in the configuration of gasoline production units in the future 5-15 years. The results showed that for CNPC to upgrade its gasoline, the share of fluid catalytic cracking (FCC) naphtha must be reduced, but just increasing reformate or alkylate and isomerate will result in excessive increase in benzene and aromatics contents or a great loss of gasoline octane number. Therefore, CNPC should suitably control the capacity of its FCC units and increase the capacity of reformer, alkylation and isomerization units. Most importantly, CNPC should dramatically expand the capacity of its hydrotreating or non-hydrotreating gasoline upgrading units to decrease the olefin and sulfur contents in FCC gasoline that takes a dominant share of about 80% in the gasoline pool of China.展开更多

The objective of a computerized measurement system is to measure temperature changes existing in a coal stockpile. In order to achieve this intention, the electrical signal conversion of temperatures sensed by 20 temperature sensors placed in certain points inside the coal stockpile, the transfer of these electrical signals into computer media by using analogue-digital conversion unit after applying necessary filterization and upgrading processes and the record of these information into a database in particular time intervals are provided. Afterwards, the diagrams of these time-temperature data are plotted. With the help of these graphs, the competent company will be able to examine the behavior of coal stockpiles in terms of spontaneous combustion and take necessary precautions against self-combustion beforehand.展开更多

A key subject in this quest is the future of automobile, with possibilities on powering ranging from biofuels to Hydrogen Cars (HC), to Electric Vehicles (EV). In turn, the latter is closely connected with the need to deploy Renewable Energies (RE) for electricity generation. Within such new situation, countries and governments are aware that there are new tools for fighting Global Warming (GW), and new policies could be established for winning this battle against CO2. All these initiatives will affect the future of energy corporations, notably hydrocarbon companies;and it should be noted that it will be difficult for the companies to define long-term strategies if energy policies convey upheavals, sudden changes in promoting alternatives and interruptions on activities. Hence, it is very important to adopt energy policies allowing a smooth evolution of the companies’ activities to the new energy model. After analyzing the alternatives with a forecasting-backcasting methodology, an “eclectic approach” is proposed, with the Plug-in Hybrid car with Flexible Fuel (PiHFF) as the central paradigm in the coming promoting policies.展开更多

Based on an analysis of the spatial structure of Samsung's three types of investment and parent company, it is put forward that regional bias exists during the operation of a multi-national corporation (MNC) in China, i.e., regional biases of technology, price, sales as well as decision-making. Front office and back ofrice, two terms related closely with the location of modern MNCs, are defined and locational principles of each are studied. It is pointed out that production companies and R&D institutions belong to back office, while sales company falls into the type of front office. Based on a summarization on the spatial distribution of production companies, sales companies and R&D institutions, the locational principles of front office and back office are then applied in explaining the location of Samsung's operating entities in China. By analyzing the spatial structure and locational principles of Samsung, a typical MNC in China, this paper aims to understand the internal operating mechanism of modern MNCs and then bring assistance to related policies to cope with those problems about MNCs that have attracted growing attention in recent years.展开更多

文摘The extraterritorial application of international human rights conventions is the legal basis for states to regulate the extraterritorial human rights obligations of transnational corporations.In recent years,it has been increasingly challenged by the new trend of the United Nations governing the human rights responsibilities of transnational corporations.A study of existing international rules and practices shows that the extraterritorial application of international human rights conventions depends on the extraterritorial jurisdiction of the States Parties,which mainly includes the actual control over extraterritorial territories and individuals as well as the execution of authority outside the territories.In view of the above,if human rights violations by individuals or transnational corporations occur in areas outside their home territories or are authorized and orchestrated by the home state,the home state shall bear the corresponding human rights responsibilities.Given the restrictive scope of the abovementioned extraterritorial application of international human rights conventions,the international cooperation obligation and the"do no harm"principle may become a new legal basis for states to fulfill their extraterritorial human rights obligations in the future,thereby expanding the basis for the extraterritorial application of international human rights conventions to deal with more serious issues of human rights violations by transnational corporations.However,on the whole,the current identification and codification of states regulating the extraterritorial human rights obligations of transnational corporations should respect the existing rules of international human rights law and should not add any new human rights obligations on states.
