Anxiety Levels

COVID-19 is the worst pandemic of this millennium, and it is considered to be the “public enemy number one.” This catastrophe has changed the way we live in the blink of an eye. Not only has it threatened our existence and health status, but the damage associated with it could equally affect our economic, social, and educational systems. The focus of this study was on the anxiety level of university students during the COVID-19 pandemic in Saudi Arabia. The study was conducted between March and June 2020. A questionnaire was administered online, and 400 completed questionnaires were returned. In this study, the Zung self-rating anxiety scale was used to determine the anxiety levels among the respondents. The results indicated that about 35% of the students experienced moderate to extreme levels of anxiety. Anxiety was highly associated with age, sex, and level of education. These findings can enlighten government agencies and policy makers on the importance of making prompt, effective decisions to address students' anxiety during the COVID-19 pandemic. Researchers are encouraged to focus their future studies on how to develop strategies to boost students' resilience and enhance their adaptability skills for similar disasters in the future.

The COVID-19 pandemic has set new challenges for the HoReCa industry. Lockdowns have coincided with and strongly impacted the industrial transformation processes that have been taking place for a decade. Among the most important HoReCa transition processes are those related to the rapid growth of the delivery-food market and ordering meals via internet platforms. The new delivery-food market requires not only the development of specific distribution channels, but also the introduction of appropriate, very specific food packaging. Food packaging and its functionality are defined by the administrative requirements and standards applicable to materials that have contact with food and principally through the prism of the ecological disaster caused by enormous amounts of plastic waste, mainly attributed to the food packaging. To meet environmental and administrative requirements, new technologies to produce food packaging materials are emerging, ensuring product functionality, low environmental impact, biodegradability, and potential for composting of the final product. However, predominantly, the obtained product should keep the nutritional value of food and protect it against changes in color or shape. Current social transformation has a significant impact on the food packaging sector, on one hand creating a new lifestyle for society all over the world, and on the other, a growing awareness of the negative impact of humans on the environment and increasing responsibility for the planet. The COVID-19 pandemic has highlighted the need to develop a circular economy based on the paradigm of shortening distribution channels, using local raw materials, limiting the consumption of raw materials, energy, water, and above all, minimizing waste production throughout the life cycle of products, all of which are in line with the idea of low-carbon development.

Melting Slag

Industrial transition to a totally new level of resources and energy saving necessitates improving the technical level of building materials manufacturing, growing their raw materials base, the assortment, enhancing the quality of manufactured products, cutting their cost price. It requires, first of all, carrying out more detailed research in properties of clay and clay loams, and selecting optimal additives for pottery works. Such disadvantages of clays as burning sensitivity, low compression resistance and flexural strength in a burnt state, low frost resistance cause the impossibility of their application without corrective additives. It is quite difficult to find an additive which can solve all the technological problems mentioned above. This paper provides the development of mixture "clay – electro-melting slag" for ceramic brick, moreover, addition of a steel-smelting slag in the fusion mixture results in the change in mixing water content of ceramic masses, strength and coloration of ceramic samples.

Keywords: vanadium pentoxide；carbon black；reduction and nitridation；vanadium nitrogen alloy. Abstract. The V2O5 extracted from low vanadium shale and carbon black are used as raw materials to prepare briquetting samples through mixing, grinding and pressing. The samples are prereduced, final reduced and nitrated to produce vanadium nitrogen alloy with high nitrogen content. Thermodynamic analysis and experiment results show that：（1）In order to avoid V2O5 volatilization loss during reduction, the briquetting samples should be pre-reduced for 4 hours below the melting point 670°C of V2O5, which can transform V2O5 into low valence vanadium oxide.（2）During V2O5 being self-reduction under N2 atmosphere, if the final reduction temperature is below 1271°C, the VN is preferential formation; if more than 1271°C, the reduced product forms V4C3.（3）To make a product with high nitrogen and low carbon content, the final reduction and nitride temperature should be controlled below 1300°C.

The reduction design is an important orientation for the design and development of corrugated box in the low-carbon economy era. Concentrating on 02 pattern corrugated box, and in accordance with the weight-bearing principle of cartons and intended strength requirements, this paper conducts the local strengthened composition on the corrugated box casing and enhances the physical properties of cartons in circulation, stacking, storage, and other aspects, which achieves the same physical strength as the traditional process but with less raw materials. The conclusions are drawn as follows on the basis of experimental and production cases: under the premise of selecting appropriate composite materials and processes, the use of the local composite strengthening technology in corrugated box casing can produce the carton with the same compressive strength while lowering more than 15% production costs than the conventional process. The study will provide some guidance to the reduction design of the corrugated box.

Abstract As long-spanning timber floor elements attempt to achieve a meaningful market share, proof of serviceability continues to be a demanding task as international consensus remains unsettled. Initiatives to improve vibration levels are achievable, but a lack of confidence in the market is resulting in increases in margins for both manufacturers and contractors. State-of-the-art concrete alternatives are offered at less than half the price, and even though timber floors offer reduced completion costs and low carbon emissions, the market is continuously reserved. Cost reductions for timber floor elements to competitive levels must be pursued throughout the product details and in the stages of manufacturing. As new wood products are introduced to the market, solution space is increased to levels that demand computerized optimization models, which require accurate expenditure predictions. To meet this challenge, a method called item-driven activity-based consumption (IDABC) has been developed and presented in this study. The method establishes an accurate relationship between product specifications and overall resource consumption linked to finished manufactured products. In addition to production time, method outcomes include cost distributions, including labor costs, and carbon emissions for both accrued materials and production-line activities. A novel approach to resource estimation linked to assembly friendliness is also presented. IDABC has been applied to a timber component and assembly line operated by a major manufacturer in Norway and demonstrates good agreement with empirical data.

Personal Travel

Behavioural change has become regarded as a key tool for policy makers to promote behavioural change that can reduce carbon emissions from personal travel. Yet academic research has suggested that promoting low carbon travel behaviours, in particular those associated with leisure and tourism practices, is particularly challenging because of the highly valued and conspicuous nature of the consumption involved. Accordingly, traditional top-down approaches to developing behavioural change campaigns have largely been ineffectual in this field and this chapter explores innovative ways to understand and develop behavioural change campaigns that are driven from the bottom upwards. In doing so, we draw on emergent literature from management studies and social marketing to explore how ideas of service dominant logic can be used to engage consumers in developing each stage of a behavioural change campaign. Using data and insights from research conducted in the south-east of the UK, we outline and evaluate the process for co-producing knowledge about low carbon travel and climate change. We illustrate how behavioural change campaign creation can be an engaging, lively and productive process of knowledge and experience sharing. The chapter ends by considering the role that co-production and co-creation can have in developing strategies for low carbon mobility and, more broadly, the ways in which publics understand and react to anthropogenic climate change.
