In this study, the thermal treatment of two types of waste from the paper industry was investigated, paper mill sludge and sewage sludge from biological wastewater treatment plants. Hydrothermal carbonisation (HTC) and torrefaction were investigated as sustainable alternatives for solid biofuel production. Untreated samples and samples chemically pre-treated with alcoholic vinegar were subjected to torrefaction at 350 °C in N2 atmosphere, and the exhaust gases were analysed. HTC was performed at 250 °C with a residence time of 4 h. The feedstocks and the biochars produced were characterised by different analytical methods, and the effects of pre-treatment on fuel properties were studied. Both processes, HTC and torrefaction, showed inspiring results in the production of biofuels from paper industry wastes under the tested experimental conditions. A positive influence of pre-treatment on fuel properties (higher heating value, carbon content) of the obtained char was observed, and changes in the gas phase during torrefaction were observed.

Growing consumption is both necessary to end extreme poverty 1 and one of the main drivers of greenhouse gas emissions 2 , creating a potential tension between alleviating poverty and limiting global warming. Most poverty reduction has historically occurred because of economic growth 3-6 , which means that reducing poverty entails increasing not only the consumption of people living in poverty but also the consumption of people with a higher income. Here we estimate the emissions associated with the economic growth needed to alleviate extreme poverty using the international poverty line of US $2.15 per day (ref.  7 ). Even with historical energy- and carbon-intensity patterns, the global emissions increase associated with alleviating extreme poverty is modest, at 2.37 gigatonnes of carbon dioxide equivalent per year or 4.9% of 2019 global emissions. Lower inequality, higher energy efficiency and decarbonization of energy can ease this tension further: assuming the best historical performance, the emissions for poverty alleviation in 2050 will be reduced by 90%. More ambitious poverty lines require more economic growth in more countries, which leads to notably higher emissions. The challenge to align the development and climate objectives of the world is not in reconciling extreme poverty alleviation with climate objectives but in providing sustainable middle-income standards of living., (© 2023.

This article examined the repositioning of science and technology education for security and economic growth and development in Nigeria. The wreck on the nation's image by the incidences of insurgency has caused negative effects on the nation's security and economic development. Security issues are presently major challenges in Nigeria, especially in Northern Nigeria. Furthermore, the continuous rise in insecurity and deterioration in the economic development in Nigeria has called for concern among researchers and policymakers over the years. This article highlights the need for rebranding Nigerians through the internal process of repositioning the science and technology education system for national security and economic sustainability. Literature and other research papers using to gather information. The paper recommends that the nation adopt a proactive approach to improving the teaching and learning of science and technology education professionally and empowering youth while taking everlasting measures to curtail the issues of insurgencies in Nigeria. In other words, we need to reposition our youth's mental reasoning and economically empower them to certify the demands of the modern world. Repositioning Nigerian is one of the fruitful tools to achieve this objective, and rebranding directs the power and energy of Nigerians toward academic and productive goals.

Public health events (PHEs) have emerged as significant threats to human life, health, and economic growth. PHEs, such as COVID-19, have prompted a reevaluation for enhanced regular prevention and control (RPC). In this study, we focus on the core concept of prevention and control intensity (PCI), and establish a neoclassical economic growth model from the long-term and macro perspective to balance life protection and economic growth. The model construct the mechanism of PCI on economic growth through population dynamics and capital accumulation under the backdrop of RPC for PHEs. We find the conditions for PCI when the economy achieves steady state, and provides an algorithm establishing the optimal strategy that maximises per capita disposable income based on the optimal PCI and consumption. Simulation result quantifies an inverted U-shaped relationship between PCI and capital per capita, output per capita and consumption per capita in the steady state. The model suggests that, given the PHEs of inducing potential unemployment shock, it is worthwhile to combine the implementation of moderate PCI with coordinated policies of income distribution., (© 2024.

There is an increasing trend toward regionalization as higher education adapts to openness and globalization. In response, East African countries formed networks and partnerships that strengthened business, higher education, student and staff mobility, and research. This is because regionalization is embedded in East Africa's economy, politics, culture, and social norms. In addition, regionalization is influenced by internationalization and globalization. It promises development opportunities, although challenges are inevitable. This paper examines the contributions of regional student mobility to East Africa's development. We use neoliberal and world systems theories to illuminate the advantages and disadvantages of regionalizing higher education and explain how partner states can maximize opportunities and minimize challenges. Data was collected through convenience sampling of two hundred international students and two staff members in international students' offices. Data analysis revealed that the regionalization of East African higher education reflects historical power relations; it has benefits though founded on inequalities.

Universities play a crucial role in the development of any nation. The success of Higher Education Institutions (HEIs) is the bedrock of the growth in human capacity required to support the growth of an economy. However, HEIs have been criticized for not playing their rightful role in national development. This has been partly attributed to not being able to manage their performance in view of the dynamic and turbulent environment they are operating in. Most HEIs have been caught up in the "business as usual" situation preferring doing things in the traditional ways as opposed to changing with the times. As a result their survival has been at risk especially from those HEIs who have adopted the "business un-usual" mentality. It is as a result of the challenges facing Kenyan HEIs that this paper proposes an adoption of the Balanced Scorecard as a management tool in HEIs. This paper provides a review of literature on the HEI environment globally and in Kenya, highlighting the challenges faced by Kenyan HEIs and proposes the use of the BSC to address the same. The BSC is a tool that helps mainstream the vision and mission of HEIs in their activities thus making the HEIs become strategy focused organizations. The BSC is a strategic planning and management system used to align business activities to the vision and strategy of the organization and to monitor organization performance against strategic goals. Finally, a sample BSC for HEIs in Kenya is proposed. It is felt that if HEIs focused on the issues proposed and measured their performance on the issues identified, their performance will be improved tremendously.

Against the backdrop of high-quality development of the national economy, the development of each city is also facing transformation and upgrading. Cities need high-quality development, and high-quality talents are the key. The problem of attracting high-quality talents in domestic small and medium-sized cities in high-quality development needs to be solved urgently. This paper takes Huai'an, a third-tier city in China, as an example, to understand the intentions and confusions of college students when they seek employment. The qualitative approach of semi-structured interviews is employed. The study finds that in small and medium-sized cities, factors hindering college students from staying in local cities for employment include that the intensity of the government in publicizing high-quality development has not reached to most college students, the guide courses in colleges and universities meet difficulties in the process of delivery, and college students' own career planning are not guided well. In response to the above problems, this paper puts forward suggestions such as strengthening the positive interaction between schools and college students, enhancing the publicity of high-quality urban development among college students, and closely integrating college students' career guidance courses with local development. Quality development attracts more high-quality talents.

Education is a right for all children. Discriminating against either the boys or the girls has serious consequences for future national development. In Nigeria, there are alarming figures showing a large percentage of boys and girls of school age not attending formal education. The focus for this paper therefore is on the girl child bearing in mind the serious implications of not education them on the society. In 2019, 10.19 million children were found to be out of school and 38% of them were girls. Some of the factors attributed to this ugly situation in Nigeria are early marriage, early pregnancy, violence at schools, funding is targeted at boys, child/domestic labour, dangerous journeys to schools, kidnapping, poor sanitation in schools, dilapidated desks/chairs, few female teachers to encourage them to attend school, religious and traditional practices etc. The implications of not addressing these factors as identified in the paper will lead to slower economic growth and reduced income, gender disparity, child mortality rates in communities will soar, she cannot be a policy maker who influences national decisions and women will be less likely to have access to social protection. Finally, recommendations like adequate funding to the education sector, provision of enabling environment, create more awareness among rural dwellers on the need to enroll, retain and encourage the girl child to complete school, Girls4Girls and SHE4HE programmes of UNICEF be sustained, provision of adequate security for all children in and out of school were proffered.
