Published: July 2023

Valorization and utilization of brewers’ spent grain (BSG) are of great interest in terms of reducing food waste and promoting more sustainable food systems. In this study, we aimed to evaluate the nutritional value of upcycled barley/rice proteins (BRP) extracted from BSG and compare this with pea proteins (PP). A randomized, cross-over, double-blind controlled trial was conducted with twelve participants (age: 24 ± 2.8 years, BMI: 23.3 ± 3.0 kg/m2). During three separate visits with a one-week washout period between visits, participants received 20 g BRP, PP, or the benchmark protein whey (WP). Blood-free amino acids (AA) were measured to determine postprandial AA uptake kinetics. The estimated total AA (TAA) uptake of BRP was 69% when compared to WP and 87% when compared to PP. The time to reach the maximum values was similar between the three protein sources. When comparing individual essential AA responses between BRP and PP, we observed higher responses in methionine and tryptophane and lower responses in lysine, histidine, and isoleucine for BRP compared to PP. This study demonstrates that BRP exhibits comparable postprandial TAA uptake profiles to PP. The findings highlight the complementarity of BRP and PP, which may offer the potential for blending approaches to optimize protein quality for overall health.

Published: July 2023

Chronic kidney disease affects many people around the world, leading those affected to replacement therapy such as hemodialysis. People who undergo hemodialysis generally undertake 2–3 treatments per week, lasting about 3–4 h each; patients spend many hours per week in contact with nurses, building a therapeutic relationship. The purpose of this work is to assess the quality of nurses’ perceived caring attitudes and behaviors and to determine their perceptions regarding the importance of the therapeutic relationship with the assisted patients. A self-reported questionnaire composed of three sections was administered to nurses; the first section included sociodemographic questions, the second the Caring Nurse–Patient Interaction Scale (CNPI-23), and the third part of the questionnaire was composed of open-ended questions investigating patients’ expectations according to nurses, the relevance of the therapeutic relationship on their work, and its effect on themselves and/or their own job satisfaction. Statistically significant correlations and trends have been observed between nurses’ sociodemographic data and the CNPI-23 items. In the clinical care area, nurses who have a post-basic degree or more years of experience feel more competent than those in other categories; in the relational care area, women tend to feel more competent than men. No correlations were found between the humanistic and comfort care areas. According to the results, the post-basic training of dialysis nurses and the adoption of organizational strategies that encourage nurse retention should be enhanced. This study was not registered.

Published: July 2023

Formaldehyde (HCHO) is a major harmful volatile organic compound (VOC) that is particularly detrimental to human health indoors. Therefore, effectively eliminating formaldehyde is of paramount importance to ensure indoor air quality. In this study, CoAl hydrotalcite (LDH) was prepared using the co-precipitation method and transformed into composite metal oxides (LDO) through calcination. Additionally, a metal Al vacancy was constructed on the surface of the composite metal oxides (EX-LDO and EX-LDO/NF) using an alkaline etching technique. SEM demonstrated the successful loading of CoAl-LDO onto nickel foam surfaces (LDO/NF), and an extended etching time resulted in a greater number of porous structures in the samples. XRD confirmed the successful synthesis of the precursor materials, CoAl hydrotalcite (CoAl-LDH) and CoAl layered double oxides (CoAl-LDO). EDS analysis confirmed a reduction in aluminum content after alkaline etching. XPS analysis verified the presence of abundant Co2+ and surface oxygen as crucial factors contributing to the catalyst’s excellent catalytic activity. The experimental results indicated that catalysts containing metal cation vacancies exhibited superior catalytic performance in formaldehyde oxidation compared to conventional hydrotalcite-derived composite oxides. H2-TPR confirmed a significant enhancement in the participation of lattice oxygen in the catalytic oxidation reaction; it was found that the proportion of surface lattice oxygen consumption by the E5-LDO catalyst (30.2%) is higher than that of the LDO catalyst (23.4%), and the proportion of surface lattice oxygen consumption by the E1-LDO/NF catalyst (27.5%) is higher than that of the LDO/NF catalyst (14.6%), suggesting that cation vacancies can activate the surface lattice oxygen of the material, thereby facilitating improved catalytic activity. This study not only reveals the critical role of surface lattice oxygen in catalytic oxidation activity, but also aids in the further development of novel catalysts for efficient room-temperature oxidation of HCHO. Moreover, it provides possibilities for developing high-performance catalysts through surface modification.

Published: July 2023

The high penetration of renewable energy sources has necessitated the use of more energy-storage devices in Smartgrids. The proposed work addresses the development and implementation of an Instantaneous Discharge Controller (IDC) for a hybrid energy storage system. The discharge control algorithm manages the discharge of the battery and supercapacitor and protects the battery from transient currents. Hybrid energy storage systems (HESSs) are well known for providing ideal attributes such as high-power density and high-energy density for many application areas, including electric vehicles and renewable energy-supported microgrids. However, the application of HESSs for supporting shunt active filters and protecting low power density storage systems from fast variations in load has not been proposed yet. In this context, a hybrid energy storage system (HESS) is proposed here to eliminate harmonics and to support the grid by providing real and reactive power supervened by varying load conditions. This paper proffers an innovative controller for a shunt active filter unified with an HESS to effectively manage storage devices for a microgrid connected to a grid.

Published: July 2023

Group theory is the part of mathematics which addresses the study of symmetry. This paper extends the investigation of the soft group theory which Aktaş and Çağman have defined. We study new concepts in the soft group theory such as the center of the soft group, the kernel of soft homomorphism and soft automorphisms with their basic properties. Furthermore, the concept of soft point groups is introduced and the properties of these soft groups are studied. We state the concept of characteristic soft subgroups of a given soft group. Also, some theorems related to this concept are investigated. We study the characteristic soft subgroups of a given soft point group. The characteristic soft subgroups play a significant part in the study of the soft group theory and are useful for understanding the structure of a soft group and its soft automorphisms. As an application of characteristic soft subgroups, they allow us to identify and study important soft subgroups that are preserved under soft automorphisms. Also, practical applications for our theory can be conducted in future work such as the relation with other disciplines in sciences.

Ethical Issues concerning Health Data Ownership
Authors: CHA Hyunjae , KIM Junhewk
Published: July 2023

In recent years, with the rise of the data economy, the amount of personal health data that is collected and stored has increased significantly and raised ethical and legal concerns over the question of who owns this data. This article reviews the relevant legislation in Korea, the EU, the US, and Japan and shows that in the current legal context there are practical problems with the concept of health data ownership. However, rather than abolishing that concept, this article attempts to situate it in a new ethical framework. Using Fraser’s critical theory of justice, which distinguishes between issues of redistribution versus recognition, this article argues that health data ownership should be understood in terms of a just relationship between data parties and data.

Alfred Kantorowicz, “réconciliateur” entre Est et Ouest
Authors: Guillon Laurence
Published: July 2023

Den Osten und den Westen versöhnen : So könnten der Lebensweg und die geistige Laufbahn von Alfred Kantorowicz (1899-1979), Herausgeber der literarischen Zeitschrift Ost und West, zusammengefasst werden. Der Berliner Autor lehnte sich immer gegen die deutsche Teilung auf, die er als „widernatürlich“ bezeichnete. So befand er sich stets zwischen zwei Stühlen, zu bürgerlich für den kommunistischen Staat, zu sozialistisch für die Bundesrepublik. Auch wenn er doppelt so lange in der BRD (1957-1979) wie in der DDR (1947-1957) gelebt hat und wenn die Jahre, die er im Osten verbracht hat, relativ gut dokumentiert sind, bleibt dagegen sein Werdegang im Westen nach seiner Flucht 1957 eher unerforscht. In diesem Artikel wird versucht, anhand seiner autobiographischen Schriften wie seines Deutschen Tagebuches und seiner in der BRD veröffentlichten Essays diese zwei Jahrzehnte im Westen ans Licht zu bringen.
Malstrom versiegt oder Der Weggegangene bleibt immer der Weggegangene
Authors: Gillen Eckhart J.
Published: July 2023

Die ab 1982 aus Dresden und Chemnitz in die Westberliner Exklave gekommenen Neoexpressiven und Neoromantiker wie Ralf Kerbach und Peter Herrmann fanden sich, von den alten Kollegen abgeschnitten und von den neuen ignoriert, im doppelten Exil zwischen Ost und West wieder. Die beiden Kunstszenen in Westberlin, die der ehemaligen Dresdner und die der Neuen Wilden, blieben in Kerbachs Erinnerung hermetisch getrennt. Die eingesessene Westberliner Kunstszene blieb für ihn und seine Freunde eine geschlossene Gesellschaft, ebenso die Galerieszene. Zu den Neoexpressionisten jenseits der Mauer in Ost-Berlin kam ein Kontakt erst nach dem Fall der Mauer zustande. So konnten die drei Malströme sich nicht zu einem starken Strom vereinen. Dabei wurden sie trotz aller Unterschiede der Mentalitäten und der Intensität der Gefühle in den 1980er-Jahren doch getragen von einem gemeinsamen Lebensgefühl zwischen Cross-over und Mixed-Media-Szene.

Published: July 2023

Despite the recent legal advances in affective-sexual and gender diversity, LGBTIQ+ people continue to face discrimination. In education, however, few studies focus on pre-service early childhood education teachers, although addressing issues related to gender and sexual identity can be helpful for young students. This chapter explores the attitudes of pre-service early childhood education teachers towards the inclusion of LGBTIQ+ issues in their teaching, and their perceptions of their initial training in this regard. An online semi-structured interview is used for gathering qualitative data. Findings show that the participants consider that this type of content should be included in their teaching but adapted to the age of the pupils, as it favors equity, promotes positive values, and helps the integration of LGBTIQ+ students. However, participants also reveal that their university training in this area has been scarce and superficial. The study encourages further teacher training in LGBTIQ+ issues.

A data-driven reduced-order model for rotor optimization
Authors: Peters Nicholas , Silva Christopher , Ekaterinaris John
Published: July 2023

Abstract. For rotor design applications, such as wind turbine rotors or urban air mobility (UAM) rotorcraft and flying-car design, there is a significant challenge in quickly and accurately modeling rotors operating in complex, turbulent flow fields. One potential path for deriving reasonably accurate but low-cost rotor performance predictions is available through the application of data-driven surrogate modeling. In this study, an initial investigation is undertaken to apply a proper orthogonal decomposition (POD)-based reduced-order model (ROM) for predicting rotor distributed loads. The POD ROM was derived based on computational fluid dynamics (CFD) results and utilized to produce distributed-pressure predictions on rotor blades subjected to topology change due to variations in the twist and taper ratio. Rotor twist, θ, was varied between 0, 10, 20, and 30∘, while the taper ratio, λ, was varied as 1.0, 0.9, 0.8, and 0.7. For a demonstration of the approach, all rotors consisted of a single blade. The POD ROM was validated for three operation cases: a high-pitch or a high-thrust rotor in hover, a low-pitch or a low-thrust rotor in hover, and a rotor in forward flight at a low speed resembling wind turbine operation with wind shear. Results showed that reasonably accurate distributed-load predictions could be achieved and the resulting surrogate model can predict loads at a minimal computational cost. The computational cost for the hovering blade surface pressure prediction was reduced from 12 h on 440 cores required for CFD to a fraction of a second on a single core required for POD. For rotors in forward flight, cost was reduced from 20 h on 440 cores to less than a second on a single core. The POD ROM was used to carry out a design optimization of the rotor such that the figure of merit was maximized for hovering-rotor cases and the lift-to-drag effective ratio was maximized in forward flight.

The article describes a study conducted by naturalists from Pune, India, in collaboration with an NGO called RANWA. The study aims to assess the biodiversity and environmental changes in the Pune urban area. The researchers standardized the methodology and focused on living organisms as indicators of ecosystem health. They classified habitat types into wilderness zones (forests, scrub, grasslands) and impacted zones (plantations, agriculture, habitations). The study area extends approximately 30 km from the City Post office and includes Pune and Pimpri-Chinchwad Municipal Corporations. The results show varying diversity levels across organismic groups and habitat types, with some species being sensitive to human impact while others are more tolerant. The study also highlights ongoing changes in the landscape, including habitat destruction due to urban expansion and infrastructure development. The researchers emphasize the importance of ecological monitoring and restoration efforts and hope that their study will contribute to generating scientific data for environmental protection.

The general state of a population's health system can be seen in the maternal morbidity and mortality rates. Despite the obvious benefits of postnatal healthcare services literature reveal that these services are frequently underused, especially in underdeveloped countries such as Pakistan. Objective: To identify the family traits that were thought to be the biggest factor of using the available postnatal health care services. Methods: According to the nature of the study quantitative research method was used. 323 females who were not currently pregnant but had given birth to one or more children selected in the sample of the present study. Final sample was chosen using a multistage sampling technique. Binomial logistic regression analysis was performed to examine the association between family traits and the use of postnatal healthcare services. Results: Results showed that 76.5% of respondents had their postpartum hemorrhage evaluated. The majority of participants (83.6%) and those who took contraceptives after giving birth (83.1%) got breastfeeding support. Results of the current study showed that the number of postnatal care visits was significantly correlated with the husband's age, education, and family's monthly income.  Postnatal care was also connected to the husband's age, education, and family income levels. Conclusions: According to the study's conclusions, education should be targeted towards enhancing the significance of postnatal care services. To address the issue of health care service utilization, policy level actions are required to maximize the ratio of the utilization of postnatal care services.

An Ex Post Impact Assessment of Municipal Restructuring in Finland – What Can We Learn?

A law-drafting process and decision-making should be based on a proper evidence base of the costs and benefits of different regulatory options. Too often, however, regulatory processes lack an adequate scientific evidence base to carry out decent impact assessments. One important and useful way to strengthen the evidence base for forthcoming regulatory reforms is to accomplish ex post impact assessments of past reforms. The necessity for ex post impact assessments has been apparent, for example, in the local government sector, as in several countries the regulator has considered municipal mergers as a panacea for improving the financial position of local governments. In this study, an ex post impact assessment of Finnish municipal structure regulation is conducted. More precisely, the study analyses the impacts of Finnish municipal mergers that were accomplished during the so-called PARAS reform, which took place between 2007 and 2013. The impact assessment is focused on examining the achievement of the objectives set for the PARAS reform in terms of expenditures and vitality. The impacts of the mergers are analysed using the Difference-in-Differences (DiD) methodology on two previously quite unexplored fields in merger literature: business activities (vitality) and comprehensive schooling (expenditures). The results reveal that municipal mergers have not caused any expenditure-moderating and productivity-enhancing effects on comprehensive schooling and no positive effects on the location decisions of business activities. In summary, municipal mergers are not the proper regulatory alternative to moderate the expenditure growth of municipalities, nor do mergers turn municipalities more attractive for residents and businesses and enhance vitality in this manner.

A Critical Evaluation of the Effectiveness of Grenada’s Legislative Responses to the COVID-19 Pandemic

The extent to which nations have been adequately equipped to deal with the severity of the COVID-19 pandemic and its ensuing fallout has been hotly contested, and the legislative responses of states have varied. This article aims to conduct an evidence-based assessment of how well Grenada’s legislative responses to the COVID-19 pandemic performed the objectives they set out to achieve, identifying any changes that occurred, the extent to which these changes were influenced by the legislation or by other non-legislative factors and the primary actors affected by these changes. This assessment features and tests Mousmouti’s criteria of legislative quality, collectively characterized as the ‘effectiveness test’, which evaluates legislative purpose, structure, content and results.

Basal stem rot is one of the important diseases of coconut accounting to severe yield loss in southern India. The disease in Indian subcontinent is reported to be caused by G. lucidum (Leys.) Karst., G. applanatum (Pers.) Pat. And G. boninense. Present status of the disease pertaining to occurrence and distribution in major coconut growing states, symptomology, etiology and epidemiology, disease indexing, pathogen diversity and its management methods are reviewed. The disease if unattended, is becoming a major threat to coconut production in Andhra Pradesh, Karnataka and Tamil Nadu states. Management of the disease is possible with continuous monitoring and implementing biocontrol based integrated management even though there is variation among the pathogenic virulence of Ganoderma isolates. As early disease escapes detection, recent developments in early detection, grouping and molecular identification of the pathogen and integrated disease management measures are summarized in this review paper.

Published: July 2023

Urban sprawl is a global phenomenon of present era and is mostly taking place in less developed countries. In LDCs there is a consistent and vibrant trend among the people to agglomerate in mega cities and large urban centers. This phenomenon has gained the attention of researchers in the fields of urban geography, environmental studies and city & regional planning. Keeping in view its importance, an attempt has been made to explore the use of geo-informatics techniques for the assessment of urban sprawl in Faisalabad city. The result inferred from the classified Landsat image for year 1980 revealed that the total built-up area of Faisalabad was 5661 hectors (26 per cent of total) while year 2010 classified Landsat image depicts that the total built-up area was 9480.44 hectors (44 per cent) of the City. The total areal change for 30 years research span (1980-2010) was 44 per cent in built up land, contrary to this non built-up /open area decreased to 32 per cent during the same period. The total area in 1980 was 102 sq. km while the city grew up to 213 sq. km by year 2010. This appreciable change in built up lands was at the expanse of fertile agricultural tracts once part of the fringe of Faisalabad city.
