The automotive sector is one of the most important economically, it not only generates direct employment, but also provides jobs to the entire associated industry. Today, component manufacturers and suppliers face disruptive changes. Electronics, which plays a fundamental role in innovation, new companies and technological giants, who claim their place in the sector; and the mentality of consumers, which opens towards other forms of mobility are some of the irruptions to which face. This article reviews the current literature and exposes the situation that the automotive sector is going through. Component suppliers that have not yet taken the step towards mechatronics or that lack high added value products will have to undergo an industrial regeneration, changing their design processes, if they want to remain competitive and continue in the sector.

Social Wellbeing

The paper explores potentials for increasing residents' wellbeing in multi-family social housing (MSH) undergoing energy renovation. The renovation measures needed to reach national and global climate goals are often not financially feasible when viewed in isolation. Therefore, it is relevant to identify potentials for added value, which can justify more extensive measures. This paper is based on the hypothesis that every renovation project holds potentials for added value in terms of increased resident wellbeing. Further, that it is crucial to extend current understandings of wellbeing beyond single, quantitative wellbeing parameters in order to promote more holistic, long-term sustainable renovation solutions. The paper sheds light on potentials for increased resident wellbeing based on an analysis of residents’ experience and satisfaction with gestures in the existing built environment and comparing these findings to their perceived health. The analysis is based on data collected through a mixed-methods approach in three MSH areas facing extensive renovation. The findings demonstrate and exemplify that energy renovation measures may influence a number of interrelated physiological, mental and social wellbeing aspects across scales. As such, the paper contributes with new insights, which can help promote previously neglected aspects of resident wellbeing in future energy renovation design processes.

Soluble coffee offers the combined benefits of high added value and practicality for its consumers. The hydrolysis of coffee polysaccharides by the biochemical route, using enzymes, is an eco-friendly and sustainable way to improve the quality of this product, while contributing to the implementation of industrial processes that have lower energy requirements and can reduce environmental impacts. This work describes the production of hydrolytic enzymes by solid-state fermentation (SSF), cultivating filamentous fungi on waste from the coffee industry, followed by their application in the hydrolysis of waste coffee polysaccharides from soluble coffee processing. Different substrate compositions were studied, an ideal microorganism was selected, and the fermentation conditions were optimized. Cultivations for enzymes production were carried out in flasks and in a packed-bed bioreactor. Higher enzyme yield was achieved in the bioreactor, due to better aeration of the substrate. The best β-mannanase production results were found for a substrate composed of a mixture of coffee waste and wheat bran (1:1 w/w), using Aspergillus niger F12. The enzymatic extract proved to be very stable for 24 h, at 50 °C, and was able to hydrolyze a considerable amount of the carbohydrates in the coffee. The addition of a commercial cellulase cocktail to the crude extract increased the hydrolysis yield by 56%. The production of β-mannanase by SSF and its application in the hydrolysis of coffee polysaccharides showed promise for improving soluble coffee processing, offering an attractive way to assist in closing the loops in the coffee industry and creating a circular economy.

Family businesses are considered as an important source of economic development and growth in that they create added value by providing new products, processes and technologies. Family businesses, where family values and perspectives dominate, have begun to experience problems in adapting to such a structure in the global economy, where the rate of change has increased, and the competition is intense. In the process of restructuring, entrepreneurial orientation is vital for these businesses. From this point of view, the aim of this chapter is to define family business, to explain their characteristics and to show the two perspectives on the entrepreneurial orientation of family businesses. The concept of “family entrepreneurship” and “transgenerational entrepreneurship” is also mentioned in the chapter. In relation to what is told in the chapter, how a conservative structure has been opened to the market by its third generation, a family business in Turkey that is going through its third generation and the innovations brought about by the new generation compose the case study.

Process Fluid

Energy sustainability and environmental protection in general are at the heart of engineering and industry discussions. Countless efforts have been devoted to improving the energy efficiency of industrial processes and specifically to harnessing their waste energy sources. One such source is waste from agro-industrial processes, which is frequently characterized by increased temperatures and high polluting potential. There are multiple available choices for exploiting energy from such waste, but this paper proposes a new alternative technique that substantially improves the efficiency. Based on the technology of leveraging a hot liquid effluent for heating a process fluid, this system introduces a third liquid to be revalorized by drying that is placed in between the hot and cold liquids. By adding stirrers inside the heat exchanger, the thermal resistance of the third fluid is reduced to a negligible level. Thus, this system has almost the same advantages as the previous one, but with the added benefit that it allows drying of a third fluid. One of the specific applications of this proposed technology is using heat from waste effluents to obtain dried food products. In the present work, it was used to dry slaughterhouse blood to obtain so-called “blood meal”, a product with a high added value that is used as pet food or organic fertilizer, and also has many other industrial applications. As shown here, the new technique outperforms existing alternatives in terms of energy efficiency and economic profitability.

Summary Wastes from industrial processes which use lignocellulosic materials as raw material are an interesting source of chemicals since they can be transformed into products of high added value. In the process described here, ozone was used to produce oxyaromatics from a lignin-rich industrial waste resulting from the production of furfural from almond shells. Ozonation, thioacidolysis and mild alkaline hydrolysis were used to determine some structural features of the raw and acid-hydrolyzed almond shell lignins. During ozone treatment of the different lignin solutions the following compounds were identified: glycolic, oxalic, malonic, glyceric (trace), malic, p-hydroxybenzoic and vanillic acids, p-hydroxybenzaldehyde, vanillin, syringaldehyde and hydroquinone. The aromatic aldehydes passed through a production maximum during the first few minutes of the reaction, while glycolic and oxalic acid (the main aliphatic acids) yields increased throughout the treatment. Raw almond shell lignin had a typical hardwood composition [made up of guaiacyl (G) and syringyl (S) phenylpropane units] and few β-O-4 structures. Acid-hydrolyzed almond shell lignins had a more condensed structure than the above. The S/G ratio obtained by ozonation was slightly lower than that obtained by thioacidolysis, with the (S/G)Ozonation/(S/G)Thioacidolysis ratio ranging from 0.52 to 0.70. The almond shell lignin-polysaccharide complex did not contain any cell wall-esterified p-hydroxycinnamic acid (p-coumaric and ferulic acids).

Solder Joint Fatigue

Electronic products used in autonomous vehicles can be subjected to harsh road conditions. Transportation induced vibration is one such reliability risk to be addressed as part of qualification. Vibration use data and reliability models are very extensively studied for fully packaged systems exposed to vibration risks during shipping. MIL-STD-810G and ISTA4AB are some of the industry standards that address these risks. On the other hand, USCAR-2 and GMW-3172 are couple of standards that may be more relevant for electronics used in automotive applications, where electronic components are exposed to vibration risks during their entire lifetime. Even though the usage model and duration for fully packaged systems in shipping and automotive electronics are different, the source of energy (road conditions), driving the risks are similar. The industry standards based damage model appear to be generic, covering a wide variety of products. In this paper, a knowledge based qualification (KBQ) framework, is used to map use conditions to accelerated test requirements for two failure modes: solder joint fatigue and socket contact fretting. The mechanisms chosen are distinct with different damage metric and drivers. The KBQ obtained qualification requirements were discussed relative to standard requirement with the objective to verify how well industry standard models reflect field reliability risks. For the chosen failure mechanisms and use condition data, it was observed that the industry standards lead to erroneous conclusions about vibration risk in the field.

Cognitive behavior therapy (CBT) is one of the major counseling theories today. However, reliability of this theory has received criticism from other theories, which claim to cognitive interventions do not provide added value on behavioral interventions. The theory criticized and showed dissatisfaction with the practice of CBT is the theory of Acceptance and Commitment Therapy (ACT). Furthermore, ACT is known to a new generation of CBT.ACT is one of the new counseling approach that can be applied to school counselors to deal with the issues of students in the school.
