This study focuses on the optimization of the burning temperature of furnace-incinerated rice husk ash (RHA) into a concrete mix design. The primary objective of this study is to investigate the optimum proportion of incineration temperature required to develop an amorphous silica from rice husk wastes and to determine the compressive strength of blended cement replaced partially at the ratio of 5%, 7.5%, 10.0%, and 12.5% of RHA, incinerated at temperatures of 600 °C, 700 °C, and 800 °C. The experimental test specimens, consisting of concrete cubes, were prepared and tested after 7, 14, and 28 days of water curing. The pozzolanic reactivity of RHA highly depends on the silica form. The silica form in the RHA is analyzed by chemical composition analysis and x-ray diffraction analysis based on the incineration period to decide if it is in the amorphous or crystalline form, with the identifying sample having a greater influence on the compressive strength. This study shows that the presence of RHA in concrete tends to improve compressive strength, especially at the early stages of curing, and the optimum replacement of cement with RHA in the concrete was 7.5% at the incineration temperature of 700 °C.

OBJECTIVE

To assess the therapeutic efficacy of acupuncture in combination with Chinese herbs for treatment of horses affected with anhidrosis.

ANIMALS

44 horses affected with anhidrosis for up to 3 years’ duration were enrolled. Inclusion required both compatible clinical signs and results of a quantitative intradermal terbutaline sweat test.

METHODS

Study horses were randomly allocated into 2 groups. Group 1 (n = 19) was treated with daily Chinese herbs and 4 weekly acupuncture sessions. Group 2 (n = 25) was given daily hay powder as a placebo and 4 weekly sham acupuncture sessions. Horses were tested by quantitative intradermal terbutaline sweat test within 2 days after treatment completion and again 4 weeks following treatment.

RESULTS

Terbutaline-induced sweat responses (mg) were not different between groups within 2 days and 4 weeks after treatment. Two days after treatment, ratios of sweat responses (compared to baseline) were higher (P < .05) in the treatment group compared to the placebo group at terbutaline concentrations of 1.0, 100, and 1,000 µg/mL. The number of horses responding to treatment was higher in the treatment group (5/19 [26%]), compared to horses in the placebo group (1/25 [4%]) for 1 of 5 terbutaline concentrations 2 days (10 µg/mL) or 4 weeks (0.1 µg/mL) after treatment.

CLINICAL RELEVANCE

Ratios of sweat responses were higher in treatment horses 2 days after treatment, compared to baseline, but not 4 weeks later. The efficacy of a traditional Chinese veterinary medicine protocol for anhidrosis treatment with acupuncture and Chinese herbs was low but higher in treated horses compared with placebo.

Published: December 2023

Due to the short shelf life of fresh apricots, special postharvest preservation techniques and practices are necessary to avoid significant economic losses. The purpose of the current study is to bring to light an approach that can be used to extend the storage life of apricot fruits treated with essential oils (EOs) (peppermint, thyme and carob EO) and examine the effects of two altitudes (1000 m and 1200 m) on the organic acid levels and respiration rate of apricot fruit during long-term storage. The results show that growing apricots at high altitudes increases the level of organic acids in the fruit, improving its quality and extending its postharvest life. Additionally, treating apricots with EOs postharvest slows down the respiration rate, reducing the consumption of organic acids during storage compared to the untreated fruit. The organic acid content was significantly higher in ‘Kabaaşi’ than in ‘Hacihaliloğlu’, and fruit harvested at 1200 m had significantly higher levels of organic acid than the fruit harvested at 1000 m. During storage, the highest organic acid content and the lowest respiration rate were observed in the fruit of both cultivars treated with peppermint, carob, and thyme oil, as compared to control fruit, respectively. To summarize, the use of EOs as postharvest treatment for apricot is recommended for maintaining the quality of the fruit during extended storage.

The recycling of waste in civil engineering is important as long as it reduces costs and protects the environment. In several countries of the world, different wastes have been used to replace cement or aggregates, such as mineral admixtures, powders and fibers. The aim of this work is to study the influence of fibers from factories and lathing workshops on concrete slump, compressive strength and 3-point flexural strength. The tests have been carried out on concretes containing different types of fibers: stretched steel fibers, fine steel fibers, looped steel fibers and looped aluminium fibers, in proportions varying from 1% to 3% by weight of aggregate. The results show that the behaviour of the concrete in the fresh and hardened state is different depending on the fiber type and content. Fiber distribution analysis was carried out to support the discussion of the results using Gwyddion software.

Concrete is the mostly used construction material composed of a mixture of cement, water, aggregates (such as sand, gravel, or crushed stone), and often additional additives or admixtures. It is widely used in the construction industry for various applications due to its strength, durability, and versatility. Key characteristics of concrete include strength, durability, versatility, fire resistant, cost effective, weather resistant, insulation and decorative options. Concrete plays a vital role in the construction industry, providing the foundation for most buildings, infrastructure, and many other structures worldwide. Its composition and properties can be tailored to meet specific project requirements, making it an indispensable material in modern construction. Various fibers can be used to enhance the mechanical and bonding properties of concrete. Also waste fibers after recycling can be reduced the environmental burden. Keeping in this view, glass powder sodium silicate glass (SSG) is used as replacement of cement with different percentages 0%,4%,8%, and 12% in combination of xanthan gum 0.2% for all mixes. An experimental study is conducted to investigate the mechanical and durability properties of concrete by performing compression test, flexural test, alkali silica reactivity test, sulfate resistivity test and drying shrinkage test. For this, forty-eight concrete cylinders are prepared for compression test, forty-eight concrete prisms for flexural test and thirty-six mortar bars of four mixes are prepared for durability testing. Workability is checked of fresh concrete during the pouring of concrete cylinders. Poured cylinders’ samples are left for 7, 14, 21 and 28 days of curing. Different tests are performed on hardened concrete and mortar samples to evaluate the mechanical and durability properties. Results concluded that workability of four mixes lies between 60-80mm and compressive strength of concrete has been improved using glass powder (SSG). Optimum results have been achieved at 12% as compared to other mixes 4% and 8% of concrete samples. Fibrous material is used as a binding agent and fibrous concrete is suitable for humid environment where high strength and voids less concrete are required. Quantity of cement can be reduced by using different fibers as a replacement of cement. Research recommended that recycled glass powder can be used in concrete as construction material and 12% replacement is suitable for optimum results.

Published: December 2023

In order to design a ventilation system based on the volumetric airflow rate, which will ensure satisfactory indoor air quality and, at the same time, do not oversize the system, it is necessary to know the quantities of pollutants emissions. The concentration of produced pollutants allows the calculation of the required fresh air volumetric flow rate. Two previous published studies are analysed in this article, whose results complement each other. From the calculated values, the graphical dependence between the required fresh air volumetric flow rate and the level of physical activity was developed. It was noticed that, according to the Slovak and Romanian legislation, for the studied gym, there is insufficient air ventilation. At an allowed maximum CO2 concentration level of 1,000 ppm, the required fresh air volumetric flow rate, according to legislative requirements, will ensure a percentage of only 75.59% to 23.25% of the necessary rate (depending of the type of physical activity). For a lower allowed maximum CO2 concentration level, the ensured fresh air volumetric flow rate will be even smaller. The aim of the article is to contribute to the development of healthy environments in fitness centres and gyms and to optimize the design requirements for their ventilation systems.

Published: December 2023

This study investigated the factors influencing hospitality property prices in the context of COVID-19. Previous research primarily focused on luxury hotels, and it lacks a comprehensive analysis of the entire hospitality sector. The study analyzed transaction data of 586 hospitality properties nationwide from 2018 to 2021. We model all the regional economic, physical, locational, and market characteristics. We use pooled OLS specification with all the interacting variables with COVID-19 period (2020 and 2021) dummy variables.
We found that both the residential areas dummy and annual growth of the apartment price index showed positive signs during the COVID-19 period. This study shows that hospitality properties were sold during the period as a residential alternative, such as conversion to officetel.
The Landscape of Inequality in Residential Capitalism: Focusing on the Marginalized Impacts of Income Inequality on Housing Inequality
Authors:   Korean Association for Housing Policy Studies, Lee Hoobin , Hong Dasom
Published: December 2023

The scholarship of residential capitalism contends that capitalist inequality was reshaped centering around housing problems. However, the importance of housing inequality, particularly compared to conventional income inequality, should be identified to demonstrate the argument. If people cannot purchase houses and accumulate assets due to low income, housing inequality is only the result and extension of income inequality. Thus, this study contrasts income and housing inequalities using the concept of housing income, a measure of monetizing the relative benefits of homeownership to other tenures. The results suggest that the housing income of Chonsei households is not higher than that of rental households, and the 2nd to 4th income quintiles have lower housing income than the 1st income quintile. This implies that high income cannot guarantee a dominant position in the landscape of housing inequality in South Korea. Moreover, the result implies that the housing tenure hierarchy (homeownership-Chonsei-rent), which traditionally intermediated housing and income inequalities, does not work anymore. The differentiation of housing inequality from income inequality is especially prominent in the 2nd to 4th income quintiles of Chonsei households. These households utilized debts, called Chonsei deposit loans, to keep up with the rising Chonsei prices, but it aggravated interest burdens and reduced Chonsei households’ monetary benefits in housing income. In conclusion, although Chonsei households could sustain their housing tenure via debts, it closed the gap between Chonsei and rent.
Du numérique au dynamisme, métamorphoser l’esprit du design de l’agriculture
Authors: Pouteau Sylvie
Published: December 2023

L’agriculture manifeste l’intrication constitutive du design des territoires, des plantes cultivées, des nourritures et des vies humaines. L’obscurcissement des liens qui sous-tendent cette intégration a fait disparaître peu à peu la compréhension des dynamismes inhérents aux processus naturels, en particulier ceux qui prennent part à l’édification des plantes et des nourritures. Pour le voir, il est nécessaire d’examiner quel type de rationalité oriente l’esprit du design vers la modernisation agricole et l’agriculture numérique. Cet examen prend son éclairage dans la conception de la connaissance chez Goethe, pour qui le tout ne prend sens qu’à la condition d’intégrer l’idée centrale de métamorphose. Cette conception s’applique à tous les plans d’organisation, et donc à l’esprit même du design. Comme antidote à une désintégration des liens qui unissent, les plantes se révèlent une leçon de métamorphose capable de guider l’innovation au service de territoires animés de vie.

Mixed community microalgal wastewater treatment technologies have the potential to advance the limit of technology for biological nutrient recovery while producing a renewable carbon feedstock, but a deeper understanding of their performance is required for system optimization and control. In Fall 2020, a 568 m3·day-1 (150,000 gal·day-1) Clearas EcoRecover microalgal treatment system was installed at the Village of Roberts (Wisconsin, USA; latitude 45.0°N) wastewater treatment plant to meet their pending effluent permit of 0.04 mg·L-1 total phosphorus (TP; 6-month average). Here we report data and analyses from continuous on-line system monitoring, long-term on-site monitoring, and on-site batch experiments, with particular focus on a 3.5 month winter period with limited outside influences (e.g., no major upstream process changes). Across this period of intensive monitoring, effluent TP concentrations were consistently below 0.03 mg-P·L-1 for 3 months. Core microbial community taxa included Chlorella spp., Scenedesmus spp., and Monoraphidium spp., and key indicators of stable performance included near-neutral pH, sufficient alkalinity, and a diel rhythm in dissolved oxygen. By tracking elemental and biochemical composition of the biomass, we also demonstrated the importance of carbohydrate storage (in photobioreactors) and mobilization (in a dark mix tank) in achieving reliable nutrient recovery and algal growth.

Published: December 2023

Hydrogen atom transfer (HAT) reactions are important in many biological systems. As these reactions are hard to observe experimentally, it is of high interest to shed light on them using simulations. Here, we present a machine learning model based on graph neural networks for the prediction of energy barriers of HAT reactions in proteins. As input, the model uses exclusively non-optimized structures as obtained from classical simulations. It was trained on more than 17,000 energy barriers calculated using hybrid density functional theory. We built and evaluated the model in the context of HAT in collagen, but we show that the same workflow can easily be applied to HAT reactions in other biological or synthetic polymers. We obtain for relevant reactions (small reaction distances) a model with good predictive power (R2 ∼ 0.9 and mean absolute error of < 3 kcal/mol). As the inference speed is high, this model enables evaluations of dozens of chemical situations within seconds. When combined with molecular dynamics in a kinetic Monte-Carlo scheme, the model paves the way toward reactive simulations.
H-Tunneling Exhibiting Unexpectedly Small Primary Kinetic Isotope Effects
Authors: Roque José P. L. , Nunes Cláudio M. , Schreiner Peter R. , Fausto Rui
Published: December 2023

Probing quantum mechanical tunneling (QMT) in chemical reactions is crucial to understand and develop new possibilities of molecular design. Primary H/D kinetic isotopic effects (KIEs) beyond the semiclassical maximum values of 7‒10 are commonly used to assess QMT contributions in one-step hydrogen transfer reactions, because H-atom QMT reactions are assumed to necessarily have large primary H/D KIEs. Nevertheless, we report here the discovery of a reaction model occurring exclusively by H-atom QMT with residual primary H/D KIEs. A 2-hydroxyphenylnitrene, generated in N2 matrix, was found to isomerize to an imino ketone via domino QMT involving sequential anti to syn OH-rotamerization (rate determining step) and [1,4]-H shift reactions. This domino QMT transformation was also observed in the OD deuterated sample, and unexpected primary H/D KIEs between 3 and 4 were measured at 3 to 20 K. Analogous residual primary H/D KIEs were found in the anti to syn OH-rotamerization QMT of 2-cyanophenol in N2 matrix. Evidence suggest that the intriguing isotope insensitive QMT observations arise due to the coupling between the cryogenic N2 medium and the movement of H/D tunneling particles. Should a similar rationale be extrapolated to conventional solution conditions, then QMT may have been overlooked in many chemical reactions.
IMPA1 dependent regulation of phosphatidylinositol 4,5-bisphosphate and calcium signalling by lithium
Authors: Saha Sankhanil , Krishnan Harini , Raghu Padinjat
Published: December 2023

Lithium (Li) is widely used as a mood stabilizer to treat bipolar affective disorder. However, the molecular targets of Li that underpin its therapeutic effect remain unresolved. Inositol monophosphatase (IMPA1) is an enzyme involved in phosphatidylinositol 4,5-bisphosphate (PIP2) resynthesis after PLC signaling. In vitro, Li inhibits IMPA1, but the relevance of this inhibition within neural cells remains unknown. Here, we report that treatment with therapeutic concentrations of Li reduces receptor-activated calcium release from intracellular stores and delays PIP2resynthesis. These effects of Li are abrogated inIMPA1deleted cells. We also observed that in human forebrain cortical neurons, treatment with Li reduced neuronal excitability and calcium signals. After Li treatment of human cortical neurons, transcriptome analyses revealed down-regulation of signaling by glutamate, a key excitatory neurotransmitter in the human brain. Collectively, our findings suggest that inhibition of IMPA1 by Li reduces receptor-activated PLC signaling and neuronal excitability.
Lebanese-Turkish Relations after the 2000s and the Neo-Ottomanist Discourse in Lebanon
Authors: YILDIZ Tuba
Published: December 2023

Lebanon, had non-visible relationships with Turkey after its independence and the post-civil war period. Although it lost the balance of political stability at times, the political affinity that emerged with the participation of Lebanon in the close relations, which Turkey sought to establish with Arab countries in the 2000s, continued with mutual negotiations at the point of cooperation. After the Lebanon-Israel war in 2006, which caused political and economic destruction in the country, Turkey increased its support for Lebanon. Accordingly, the crises appeared after the Arab Spring in the region led Turkey to follow the sensitive policy over the sectarian groups in the country. However, some reactions arose in Lebanon’s political arena against Turkey’s increasing regional activism, bringing several ideological questions on Turkey’s approach towards Lebanon. Regarding the relationship between Turkey and Lebanon, “Does Turkey desire to establish a new Ottoman administration in the Middle East?” was one of the questions asked. Moreover, a negative environment was created and used occasionally as a trump card against Turkey’s approach toward Lebanon, saying that even the Ottoman Empire did not play an active role in the Lebanon region.
This study examines whether there are traces of Neo-Ottomanism and sectarianism in the political roadmap followed by the Turkish Government in its Lebanon policy. It discusses, the diplomatic response of Turkey to the anti-Ottoman rhetoric in Lebanese politics and its effect on bilateral relations. Accordingly, the study analyzes Turkey’s effort to maintain the balance against sectarian discourse that shapes Lebanon’s policy.

Published: December 2023

Today, the problem of diagnosing malignant diseases of the skin of the face, the medial corner of the eye and the trunk worries many researchers. This is due to the increase in recent years in the number of patients with malignant neoplasms of the skin, not only of the face, but also of the body. Malignant skin tumors are: squamous cell carcinoma, basal cell carcinoma, cylindroma (adenocystic carcinoma, basal cell carcinoma with hyaline stroma, cystadenoid carcinoma). Melanoma is a skin tumor that develops from pigment (color) cells - melanoblasts. Cylindroma is an epithelial tumor characterized by the formation of cylindrical structures with stroma hyalinosis. The tumor is prone to infiltrating growth along nerve branches and trunks.Objectively, in patients with BCC, it looks like a red formation protruding above the surface of the skin, which is covered with scales and has become hard over time. A bleeding ulcer forms in the center of the skin lesion. In patients with PKR, it objectively looks like a yellow scaly part, with a tender surface, which also bleeds when touched. An ulcer also forms at the site of such a lesion.Conclusion.The effectiveness of treatment and 5-year survival of patients with malignant skin tumors depends on G, the stage of the disease and the spread of the process.To reduce the number of skin cancer diseases, it is necessary to carry out prevention, that is, to exclude the effects of harmful factors, to conduct sanitary and preventive conversations.Today it is known that the main method of treatment of patients with skin cancer is surgical with determination of the border of the tumor lesion.Key words: skin cancer, diagnosis, treatment methods, malignant diseases, eye diseases

Published: December 2023

Corn is the most produced cereal in the world, used both in human and animal nutrition. This study aimed to compare the fit of the Logistic, Gompertz, and von Bertalanffy non-linear models to data on the accumulation of total dry mass, dry mass of stems, leaves, and ears in corn plants grown with straw mulch from common bean, millet, and Brachiaria brizantha in relation to the days after plant emergence. The assumptions of normality, homoscedasticity, and independence of residuals were checked by Shapiro-Wilk, Breusch-Pagan, and Durbin-Watson tests, respectively. The models were adjusted by the least squares method using the Gauss-Newton algorithm in the R software. The quality of the fit was evaluated based on the values of the coefficient of determination (R2), the residual standard deviation (RSD), the Akaike Information Criterion (AIC), and Bates and Watts curvature measures. The Logistic model presented the best fit for the dry mass of stems and ears, and the Gompertz model for the dry mass of leaves and total dry mass, based on the quality evaluators used.

Published: December 2023

The purpose of this study was to explore how mathematical reasoning, one of the most important topics in school mathematics, is implemented in elementary school mathematics textbook. To this end, this study analyzed the type of reasoning, level of cognitive demands, and structural characteristics of mathematical reasoning tasks provided in the elementary school mathematics textbooks. As a result of this study, it was revealed that the mathematics textbooks had the strength of providing sufficient tasks dealing with pattern recognition type, but were deficient in providing tasks dealing with multiple types of mathematical reasoning, such as making a conjecture, investigating a conjecture, developing a justification, finding a counterexample, and evaluating an argument. Regarding the level of cognitive demands of mathematical reasoning tasks, the mathematics textbooks provided sufficient tasks of procedures with connections, but insufficiently provided tasks of doing mathematics requiring complex thinking. In relation with the structural characteristics of mathematical reasoning, the mathematical reasoning tasks in the mathematics textbooks embodied only the aspects of pattern recognition-making a conjecture and pattern recognition-developing a justification, but were insufficient in embodying the structural flow of mathematical reasoning. In addition, this study suggested that elementary school mathematics textbooks need to provide a wealth of tasks dealing with multiple types of mathematical reasoning, tasks of doing mathematics, and tasks reflecting the structural characteristics of mathematical reasoning.

Published: December 2023

This study aims to explore the impact of the characteristics of remote learning on the overall mathematics classroom. Adapting Lobato et al.'s (2013) notion of “noticing as a phenomenon distributed across individual cognition, social interactions, material resources, and normed practices (p. 809),” the present study reports on similarities and differences in mathematical noticing of two elementary teachers who conducted remote learning on fractions division and how what each teacher noticed was shaped by other elements of their classroom. Although the two teachers taught the same lesson with similar tasks, there were distinct differences between the two teachers' classrooms. Similar to previous studies reporting on students' mathematical noticing, the differences in teachers' centers of focus emerged as a result of focusing interactions, features of mathematical tasks, and the nature of mathematical activities during remote learning. We concluded the study by suggesting the importance of focusing on teachers’ mathematical noticing, implications for future research, and effective professional development design for remote learning.

Introdução.A sífilis é uma infecção sexualmente transmissível (IST) sistêmica e que quando não tratada precocemente tem potencial para evoluir e apresentar sequelas irreversíveis em longo prazo. Nesse sentido, o tratamento e a adesão dos parceiros sexuais de mulheres com resultado positivo para sífilis são um desafio constante no cotidiano de trabalho dos profissionais que atendem nas Unidades Básicas de Saúde (UBS). Objetivo.Sintetizar as publicações científicas, acerca da adesão ao tratamento da sífilis pelo parceiro sexual da mulher atendida na atenção primária. Metodologia. Trata-se de uma pesquisa do tipo revisão integrativa, em que a busca na literatura foi realizada nas bases de dados LILACS (Literatura Latino-americana em Ciências da Saúde), MEDLINE (Medical Literature Analysis and Retrieval System Online), BDENF (Base de Dados de Enfermagem), BRISA (Base Regional de Informes de Avaliação de Tecnologias em Saúde das Américas), RedETSA (Red de Evolución de Tecnologías em Salud de las Américas) e IBECS (Índice Bibliográfico Español em Ciencias de la Salud), utilizando-se os descritores “sífilis” AND “tratamento” AND “parceiros sexuais”. Resultados. Os artigos em estudo foram publicados entre os anos de 2015 e 2019 e os títulos evidenciaram a problemática da sífilis, através de estudos de caráter transversal, epidemiológico, exploratório e qualitativo. Conclusão. Diante dos estudos analisados, percebeu-se que a não adesão ao tratamento da sífilis pelo parceiro sexual, permanece como um notável desafio para o controle desta patologia. Os dados verificados neste estudo confirmam a urgência de intervenções eficientes, dirigidas ao homem na atenção primária em saúde.

Objetivo: Analisar as evidências científicas disponíveis na literatura sobre sinais e sintomas, diagnóstico e medidas de prevenção da COVID-19. Metodologia: Revisão integrativa. As bases de dados utilizadas foram Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), base bibliográfica especializada na área de Enfermagem (BDENF), Índice Bibliográfico Español en Ciencias de la Salud (IBECS), no período de 2020 e 2021, com os descritores: “covid-19”, “diagnóstico” e “prevenção de doenças”. Resultados: Foram obtidos 1.722 estudos, após análises para elegibilidades ficaram 12 artigos: 3 deles abordaram sobre sinais e sintomas; 6 sobre diagnóstico e 3 sobre medidas de prevenção. Os principais sinais e sintomas encontrados foram: febre alta, tosse, dispnéia, cefaléia e dor de garganta com a tríade anosmia, augesia e febre como preditores da COVID-19. Diagnóstico: apresenta três estágios: de incubação assintomática com ou sem vírus detectável, presença do vírus com paciente sintomático e sintomas respiratórios graves com carga viral alta. Para diagnóstico o exame padrão ouro é o RT-PCR e o teste rápido após o 10º dia do início dos sintomas. Conclusão: Os estudos mostram que a origem do COVID-19 permanece incerta. O Brasil é um dos países com maior número de casos confirmados e de mortes. A transmissão ocorre principalmente de pessoa a pessoa sintomática ou não. As medidas de prevenção como higiene das mãos, uso de máscaras e isolamento social são essenciais para o controle da ameaça global. A vacina tornou-se indispensável a fim de minimizar os sintomas e, consequentemente diminuir a sobrecarga do sistema de saúde.

Inter-Organizational Leadership in Healthcare—Using Digital Services, Networks, and Digital Platforms

ABSTRACT: Firms have harnessed service-dominant logic research to understand and enhance the customer purchase journey. They’ve innovated by creating and assessing services that meet customer needs and identifying expectation gaps, which inform ongoing service development to sustain customer value. Moreover, they’ve begun to foster customer loyalty through collaborative competency and digital platforms that engage and empower customers. Healthcare organizations face particular challenges in sustaining value due to the involvement of multiple external partners in value fulfillment and assessment, all within a shifting patient ecosystem. This paper tackles these challenges by advocating for inter-organizational leadership to enhance patient health outcomes, centering on a patient value cycle aimed at specific health improvements. We utilize network theory to develop governance capabilities for collaborative competency and communication theory for resource orchestration, facilitating resource sharing with an integrated digital platform. The paper outlines a framework to create and sustain patient value within a network of health and community actors and considers how these strategies can extend to address long-term patient needs in a primary network. Finally, the paper highlights case studies from this special issue that show inter-organizational leadership in action, delivering patient value through wellness education, preventive screenings, and caregiver support for those with chronic conditions and disabilities. This sets the stage for future research into expanding these models to broader patient care contexts.

The article provides detailed information about ampelodescriptor signs, morphological, biological and technological features of the valuable indigenous grape variety Bayanshira, originating from the ancient center of viticulture – Ganja-Dashkasan zone of Azerbaijan. The enocarpological and enochemical characteristics of bunches and berries, the population structure and the variability of this variety were studied. In order to determine the direction of use and technological suitability of the Bayanshira variety yield, an uvological assessment of bunches and berries of fresh grapes was carried out, prototypes of wines of various types were prepared and their physicochemical analysis was carried out using modern methods. As a result of assessing the intrapopulation phenotypic variability of the variety, several biotypes and clonal variations were identified, their distinctive characteristics were identified and described, and morphological features, biological and technological indicators were studied. Based on the above, a number of important indicators of the biotype of the Bayanshira variety can be noted: t he size of the bunch ranged from 17,2 × 7,7 to 26,5 × 12,6 cm, the shape of the bunches was conical, the number of berries in the bunch was generally more than 200 pieces, but only biotype 6 had an average number of berries in a bunch (150 pieces), berry size ranged from 19,4 × 19,0 to 23,4 × 22,2 mm, bush yield was 4,4-12,4 kg, yield juice from berries was 48,4-84,6 %, sugar content of berry juice was 17,4-21,4 g/100 cm3 , titratable acidity was 4,65-8.02 g/dm3 , the amount of phenolic compounds was 0,25-0,45 g/dm3 , and the amount of biologically active substances was 0,12-0,36 g/dm3.
