LA DELINCUENCIA DE LOS DENOMINADOS «JÓVENES-ADULTOS» EXTRANJEROS EN ESPAÑA
Authors: Cano Paños Miguel Angel , Flores-Fernández María
Published: November 2023

España se ha visto confrontada con el fenómeno de la inmigración desde finales de la década de 1990, momento en el que el porcentaje de ciudadanos extranjeros arribados al país fue aumentado considerablemente año tras año, sobre todo con respecto a aquellos procedentes de países de Latinoamérica y del continente africano. En estos momentos, existe ya en España una consolidada segunda generación de población de origen inmigrante; y en no pocos casos, los hijos e hijas de este contingente llegado a España a finales del siglo xx tienen ya la nacionalidad española, al haber nacido en territorio español.Bajo el trasfondo de la inmigración, existe en el seno de la población española la percepción de que la delincuencia en general, y más concretamente la cometida por aquellos jóvenes de sexo masculino con edades comprendidas entre los 18 y los 25 años, viene marcada, sobre todo, por aquellas conductas delictivas cuyos autores son jóvenes, bien de nacionalidad extranjera, bien de origen extranjero, aunque con pasaporte español (segundas generaciones). En no pocos casos, son los medios de comunicación los que han venido alimentando esta percepción.Por ello, el objetivo del presente trabajo es analizar la evolución, incidencia y características que presenta la delincuencia cometida porjóvenes de entre 18 y 25 años de nacionalidad u origen extranjeros a partir del estudio de las estadísticas oficiales. La hipótesis con la que se parte es que la arriba mencionada percepción de la ciudadanía española no se ve corroborada a partir del análisis estadístico.Por último, y para contextualizar este estudio desde una perspectiva europea, se analizan también, en relación a esta concreta franja de edad de nacionalidad u origen extranjeros, los datos estadísticos de los que se disponen con respecto a Alemania y Francia; países que, ya desde hace décadas y mucho antes que el caso español, vienen estando también confrontados con el fenómeno de la inmigración.

Criticism Standards for Readings on Alzajaj and Alnahas: A Comparative Approach
Authors: Al Zaabi Shaikha
Published: November 2023

This research contains an inductive study of the style and methodology of the two imams Abu Jaafar al-Nahhas (d. 338 AH) and Abu Ishaq Ibrahim bin al-Sari al-Zajjaj (d. 311 AH) in the chapter on choosing and criticizing Qur’anic reading, and extracting the criteria and rules on which they based their opinions and choices, and the methods of graduation and grammatical guidance on which they relied. to it, and the types to which they were subjected to criticism and evaluation. The relationship between parsing and Quranic reading arose as a result of the semantic variation in linguistic sounds, due to a pronunciation or dialectal variation, and from here grammatical interpretation appeared to enhance the reader’s choice and triumph for his doctrine. This is because reading is a Sunnah to be followed, and the Sunnah is more deserving of being followed without necessarily being subject to grammatical interpretation and definitive arguments, and it shows the importance of studying the readings in correcting linguistic usage. And comprehending the specific meanings of some tribes and others who fell into their orbit, and the researcher notes that stopping at the limits of syntax only with the two Imams al-Nahhas and al-Zajjaj does not bring the desired fruit. Rather, we can expand and extend to some jurisprudential horizons without going too far, so the value of that is no less than the value of reading, its syntactic interpretations, and its grammatical directions.
Role of Public-Private Partnerships in Developing Sustainable Cities: Framework, Opportunities, Mechanisms
Authors: Leshinka Patrose Sempeyian , Tembo Moffat , Mwanaumo Erastus Misheng’u
Published: November 2023

The rapid rate of global urbanization has forced governments worldwide to develop sustainable cities through Public Private Partnerships (PPPs), which appear to offer suitable solutions that overcome the shortage of public finance and cuts on public spending. However, it is still unclear what strategies to follow when engaging private sector partners who can fulfill the requirements of PPP for sustainable cities. Based on the existing gap, the current study seeks to understand the role of PPP as a strategy for developing sustainable cities, by studying its framework, opportunities, and mechanisms. The study adopted a systematic review of relevant literature and published materials. The findings demonstrate that PPPs contribute to developing sustainable cities and further identify four common themes: Governance, Public-Private-People Partnerships (PPPPs), Sustainability, and Innovation. The study concluded that these themes are interconnected within the successful development process of a sustainable city PPP. The study further recommends adopting these themes while developing PPP frameworks and mechanisms for sustainable cities. This study adds to the body of knowledge literature on the applicability of PPPs for sustainable urban development.

Published: November 2023

Sustainability in construction has been an everlasting global goal to reduce the emission of greenhouse gases that have had detrimental effects on the environment and negatively impacted human life in general. Graphene, a two-dimensional material exhibiting exceptionally desirable properties, has shown great potential to impact the building and construction sectors significantly. Graphene and its derivatives can easily be used as an additive in concrete-based composites (CBC) to improve their mechanical and durability properties and their safety, with prospects of fostering sustainability. This paper uses a scoping and compressive thorough mixed review approach, and this research aims to assess the endeavors in utilizing Graphene and Its derivatives in cementitious composites and to chart the perspectives found in the existing literature. The paper selected 64 articles from a pool of 576 publications based on their relevance. The comprehensive review concludes that the benefit of using Graphene and its derivatives as a reinforcement in cement composites lies in its superior ability to improve mechanical properties, including tensile strength and compressive strength, and improves durability by restricting crack initiation and expansion at the nanoscale, and enhances resistance to chloride and sulphate attacks as well as improving the safety of concrete based composites, setting it apart from traditional reinforcement methods.
Career Planning Programs and Employees’ Performance in Milling Industries in Kenya. A Case Of Unga Group Limited
Authors: Muriithi James Gitari , Charles Muo
Published: November 2023

Firm growth has various undertones which can describe it in the perspective of market share change, sales growth, employment growth, total assets growth and also level of community participation. The aspect of sales growth involves revenue from sales which was considered in this study and applied as revenue change. Total assets growth was also applied to measure firm growth. Firms that create value through selling their products are rewarded by the market through generation of more revenue, which translates to profit and operating cash flow that finally accrues to the stockholders. Hence, stock performance was studied to determine if it is affected by firm growth. This study, therefore, aimed to investigate the effect of firm growth on stock performance. The study targeted the non-financial firms quoted at the Nairobi Securities Exchange in Kenya. Firm growth was measured using revenue change and total assets change. Thus, the study’s specific objectives were to determine the effect of revenue change on stock performance and establish the effect of total assets change on stock performance of non-financial firms quoted at the Nairobi Securities Exchange. The descriptive statistics indicated that the standard deviation values are all clustered around the corresponding mean. The ANOVA results depicted a statistically significant model at 5 percent. The variables are good predictors of stock performance as justified by an F statistic of 39.14 and the reported p-value of 0.0000 which is less than the 0.05 significance level. The Pearson’s coefficient findings observed that there was no correlation between revenue change and total assets change with stock performance. The panel regression results showed that revenue change and total assets change to a large extent affect stock performance of the listed firms. The study revealed that revenue change has a positive impact on stock performance and also total asset change has a positive effect on stock performance. The study therefore concluded that firm growth has a positive effect on stock performance of listed non-financial firms in Kenya.

Authors: Jamaluddin Jamaluddin
Published: November 2023

This study aims to analyze one of the rights contained in the sale and purchase transaction, namely the khiyar right. The type of research used is library research. There are two approaches used, namely the normative theological approach and the socio-economic approach. Information on data sources is obtained from primary data and secondary data with data collection methods carried out by in-depth searches of references and then analyzed comprehensively. The results showed that in the perspective of Sharia economics, khiyar is one of the rights that must be given to both parties in buying and selling transactions, but the current phenomenon is very rarely found to be implemented by both parties in the transaction. Therefore, one of the findings in this study is to provide education to the public about the importance of implementing khiyar as an integral part of buying and selling, so that both parties like each other.

Published: November 2023

Abstract
The purpose of this research is to reveal MUI's fatwa method in the study of fatwa covid 19. This research is qualitative research, the type of research is library research. The data collection method used is literature study. The research results show that; 1) There are seven fatwas that generally discuss covid 19, namely fatwa numbers 14, 17, 18, 28, 31, 36 in 2020 and number 14 in 2021. With the classification of fatwas issued in 2020, it generally discusses the organization of worship for people affected by covid 19, medical personnel who carry out their duties and worship. The organization of worship will regulate prayer in the mosque or at home, stretching the prayer sash, changing Friday prayers to rawatib prayers. All of these provisions are based on the arguments of the Qur'an, Hadith, and fiqh rules.  2) Based on the existing classification, fatwa covid 19 is a fatwa related to worship and permits aztrazeneca products. On the issue of worship, it can be seen that the fatwa pattern used is to use sharia concessions on the basis of difficult or emergency situations that occur. As for the use of astrazeneca that contains pork trypsin, MUI does not legalize it but only permits it based on the five conditions mentioned in the fatwa. The loss of the five supporters of permissibility results in the loss of emergency and makes astrazeneca haram again.
Keywords: Fatwa, MUI, Covid 19.
Abstrak
Tujuan riset ini untuk mengungkap metode fatwa MUI dalam kajian terhadap fatwa covid 19. Riset ini merupakan riset kualitatif, jenis riset  adalah riset kepustakaan. Metode pengumpulan data  yang digunakan adalah studi literatur. Hasil riset menunjukan bahwa; 1) Terdapat tujuh fatwa yang secara umum membahas covid 19, yaitu fatwa nomor 14, 17, 18, 28, 31, 36 pada tahun 2020 dan nomor 14 tahun 2021. Dengan klasifikasi fatwa yang keluar pada tahun 2020 secara umum membahas tentang penyelenggaraan ibadah orang yang terkena covid 19, para tenaga medis yang melaksanakan tugas dan ibadahnya. Penyelenggaraan ibadah nantinya mengatur shalat di masjid atau di rumah, perenggangan saf shalat, perubahan shalat jumat menjadi shalat rawatib. Keseluruhan ketentuan ini didasarkan pada dalil-dalil al-Quran, Hadis, dan kaidah fikih.  2) Berdasarkan klasifikasi yang ada pada fatwa covid 19 adalah fatwa berkaitan ibadah dan membolehkan produk aztrazeneca. Pada persoalan ibadah, maka terlihat pola fatwa yang digunakan adalah menggunakan keringanan-keringanan syariat atas dasar keadaan sulit atau darurat yang terjadi. Sedangkan pada penggunaan astrazeneca yang mengandung tripsin babi, MUI tidak menghalalkan juga tetapi hanya membolehkan berdasarkan lima ketentuan yang telah disebutkan dalam fatwa. Hilangnya kelima pendukung kebolehan mengakibatkan hilangnya kedaruratan dan membuat astrazeneca kembali haram.

HUKUM PENUKARAN BENDA WAKAF DITINJAU DARI HUKUM POSITIF DAN HUKUM ISLAM
Authors: Qoshwah Nabila Al
Published: November 2023

Wakaf merupakan salah satu komponen dari kebijakan fiskal Islam yang memiliki potensi besar dalam keseimbangan perekonomian suatu negara. Karena menyangkut harta seseorang serta urusan ibadah kepada Allah swt, hal itu sangat riskan terhadap penyalahgunaan oleh pihak yang tidak bertanggung jawab serta muncul berbagai masalah yang terjadi di masyarakat awam, salah satunya kasus penukaran benda wakaf. Tujuan penelitian ini adalah untuk mengetahui relevansi antara teori penukaran benda wakaf menurut hukum positif dan hukum Islam dengan praktik yang terjadi di lapangan melalui kasus musala Ar-Ridwan. Penelitian ini menggunakan metode deskriptif kualitatif. Berdasarkan analisis data yang telah dilakukan, dapat disimpulkan bahwa hukum penukaran benda wakaf menurut hukum positif dan hukum Islam adalah boleh, dengan syarat apabila benda wakaf tersebut sudah tidak dapat dimanfaatkan lagi demi kepentingan bersama. Namun di dalam hukum Islam tidak dibahas bagaimana pengaturannya secara rinci, selama tidak mengubah asal tujuan dari benda wakaf tersebut. Adapun dalam hukum positif mengatur mekanisme penukarannya serta syarat-syarat yang harus ditempuh dalam proses penukarannya, dengan tetap berpedoman baik pada hukum Islam, Undang-undang, Peraturan Pemerintah maupun hukum Agraria karena dalam urusan ini menyangkut pertanahan. Dan dalam praktiknya, penukaran Musala Ar-Ridwan sudah sesuai dengan pengaturan dalam hukum positif.
About the problem of obtaining information necessary to prove the guilt of persons involved in the illegal acquisition, storage and smuggling of wood.
Authors: Viatkin Andrei Anatol'evich
Published: November 2023

The subject of the study is the existing practice of investigating crimes related to the illegal acquisition, storage and smuggling of wood, the results of theoretical and applied scientific research conducted in this field. As the main factors determining the existence of the problem considered in the course of the study, the author identifies: the complex nature of criminal actions that precede the illegal export of forest products; the organized nature of criminal activity; a significant amount of information that is subject to analysis as part of the investigation; the concealment by criminals of their awareness of the illegal origin of wood and the illegality of its export. Special attention is paid to the role of witnesses in criminal cases as well as work with them. The scientific novelty of the work lies in the algorithm proposed by the results of the study for obtaining meaningful information, which consists of two stages of investigative work and takes into account the peculiarities of the method of wood smuggling, and is also focused on the above factors. In addition, it allows you to streamline the process of searching, recording and analyzing information that is necessary to solve the problem of proving the guilty of specific persons. Its application is considered by the author on the example of working with certain categories of witnesses, however, it is universal and in practice can be used by the preliminary investigation body when working with various sources of information.

Self‐assembly of proteinaceous biomolecules into functional materials with ordered structures that span length scales is common in nature yet remains a challenge with designer peptides under ambient conditions. This report demonstrates how charged side‐chain chemistry affects the hierarchical co‐assembly of a family of charge‐complementary β‐sheet‐forming peptide pairs known as CATCH(X+/Y−) at physiologic pH and ionic strength in water. In a concentration‐dependent manner, the CATCH(6K+) (Ac‐KQKFKFKFKQK‐Am) and CATCH(6D−) (Ac‐DQDFDFDFDQD‐Am) pair formed either β‐sheet‐rich microspheres or β‐sheet‐rich gels with a micron‐scale plate‐like morphology, which were not observed with other CATCH(X+/Y−) pairs. This hierarchical order was disrupted by replacing D with E, which increased fibril twisting. Replacing K with R, or mutating the N‐ and C‐terminal amino acids in CATCH(6K+) and CATCH(6D−) to Qs, increased observed co‐assembly kinetics, which also disrupted hierarchical order. Due to the ambient assembly conditions, active CATCH(6K+)‐green fluorescent protein fusions could be incorporated into the β‐sheet plates and microspheres formed by the CATCH(6K+/6D−) pair, demonstrating the potential to endow functionality.

Authors: Stincone Paolo , Naimi Amira , Saviola Anthony J. , Reher Raphael , Petras Daniel
Published: November 2023

With the emergence of next‐generation nucleotide sequencing and mass spectrometry‐based proteomics and metabolomics tools, we have comprehensive and scalable methods to analyze the genes, transcripts, proteins, and metabolites of a multitude of biological systems. Despite the fascinating new molecular insights at the genome, transcriptome, proteome and metabolome scale, we are still far from fully understanding cellular organization, cell cycles and biology at the molecular level. Significant advances in sensitivity and depth for both sequencing as well as mass spectrometry‐based methods allow the analysis at the single cell and single molecule level. At the same time, new tools are emerging that enable the investigation of molecular interactions throughout the central dogma of molecular biology. In this review, we provide an overview of established and recently developed mass spectrometry‐based tools to probe metabolite‐protein interactions—from individual interaction pairs to interactions at the proteome‐metabolome scale.

Published: November 2023

The aim of this article is to identify and estimate different inventories of emissions during construction activities. A unique approach for simulating construction materials and their stochastic embodied greenhouse gas (GHG) emissions is proposed. The % of carbon released by various equipment and materials with respect to construction activities was also measured to assess emissions inventory supported by construction project case example. Finding shows that the gross carbon emissions from construction materials was 5419.576 ton of CO2 whereas carbon emissions from sustainable construction materials was 752.383 ton of CO2. The findings of the study, which revealed a significant potential for an 86.19% reduction in carbon emissions by utilizing substitute substances in construction materials compared to conventional materials, have led to the proposal of important measures. These measures are crucial for identifying the primary sources of carbon emissions in construction activity and play a pivotal role in promoting sustainable construction practices and achieving green ratings for construction projects. The research will help sustainable construction & will pave the way for achieving an effective green rating for construction projects.
Wave-attenuation efficiency of a floating distensible tube at different Keulegan–Carpenter numbers
Authors: Mendes António C. , Braga Francisco P.
Published: November 2023

A water-filled floating rubber tube is tested in a wave flume under regular waves of different steepness. The wave excited pressure bulges in the tube induce periodic oscillations of a forward-bent water column at its stern, which in turn activate a pneumatic power take-off system. The purpose of the experiment is to better understand how the tube’s working modes contribute to the wave energy absorption and to quantify the power extracted from the incident waves. By applying Bernoulli’s equation for incompressible airflow, the water column free-surface displacement measurements deliver the pneumatic chamber pressure and the volume flow through the power take-off. Video captions help to reveal the interactions of the tube with the incident waves and further relate them to the system’s efficiency. Additionally, an energy balance enables the assessment of the internal friction and flow separation losses, at different Reynolds and Keulegan–Carpenter numbers. The hydrodynamic and overall efficiencies of the system are ultimately provided.

Geospatial characteristics of allotment garden provision in Tokyo
Authors: Kishimoto Keidai , Yan Wanglin
Published: November 2023

Allotment gardens (AGs), one of the most popular forms of urban agriculture (UA), have attracted social attention because of the ecosystem services they provide to citizens. However, the services and availability of AGs may be unevenly distributed, owing to their geographic location. The patterns underlying the provision of AG plots and facilities to users in Tokyo are unclear. Thus, this study quantitatively examines the characteristics of different types of AG provision and their determinants in the metropolitan region of Tokyo. We classified a sample of 313 AGs gathered from governmental open data via a non-hierarchical cluster analysis of AG provision patterns based on their properties, including number of plots, plot size, contract price and duration, and facilities such as agricultural equipment and access to instructors. Moreover, we examined the influence of urban development and residential characteristics on these classes using the Kruskal–Wallis test. The analysis identifies six AG provision patterns based on their properties. It also revealed that AG provision in Tokyo was differentiated by the percentage of agricultural land and the socio-demographic characteristics of residents, including population, percentage of young population, and income levels from the city center to the suburban areas, corresponding to urban sprawl. These findings could provide valuable insights to help local governments, farmers, and non-profit organizations address the challenges and opportunities arising from each AG provision pattern and to make AG plots and facilities more adaptable to upcoming urban shrinkage, business opportunities, and possible excessive subdivision and price hikes.

Published: November 2023

One of the pivotal oceanographic factors impacting the hydrodynamic attributes of the waters within the Kawal River Estuary is the prevailing current. This current pattern in the Kawal River estuary exhibits a dynamic nature, primarily under the influence of wind and tidal dynamics. The Kawal River Estuary, as a confluence zone of riverine and oceanic currents, manifests as a dynamically evolving aquatic environment. The investigation was conducted at the Kawal River Estuary in Bintan Regency during the months of September 2021 and January 2022. The research employed the MIKE 21 software, examining two distinct tidal states: high tide and low tide. In September, the sound velocity values averaged 1538.647 m/s at the water surface, 1539.984 m/s within the water column, and 1541.436 m/s at the seabed. In contrast, January recorded sound velocity values of 1534.517 m/s at the surface, 1535.613 m/s within the water column, and 1536.312 m/s at the seabed. Current velocities in September ranged between 0.02 m/s and 0.037 m/s, with a predominant southward direction, while in January, they varied from 0.02 m/s to 0.59 m/s, also exhibiting a southward trajectory. Notably, the swifter current velocities observed in January are attributed to the influence of the northern season.

Published: November 2023

Mangroves are one of the coastal ecosystems that can adapt to tidal areas with highly saline environments. This community plays a crucial role in ecological and economic functions, such as prevention of abrasion and seawater intrusion, providing habitat for biotas, nutrient recirculation, carbon sinking and storage, and mangrove educational tourism. The climatic changes and anthropogenic activities affect the mangrove ecosystem and thus need protection and conservation. The novelty of this research is that it is conducted in a marine protected area and was carried out at several stations consisting of zones such as the core zone, utilization, and others. This research does provide scientific literation about the community structure and health index of the mangrove ecosystem in the Anambas Islands as one of the first steps for ecosystem protection and management. This study was conducted at twelve stations using the squared line transect (10x10 m; 5x5 m; 1x1 m) to calculate vegetation density, and hemispherical photography method to calculate the percentage of canopy cover. The results showed that nine mangrove species were found at the study site: Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorhiza, Xylocarpus granatum, Ceriops tagal, Rhizophora stylosa, Rhizophora lamarckii, Avicennia marina, and Aegiceras floridum. The status of mangrove ecosystem in Anambas Islands is categorized as good and dense condition with a percentage of canopy cover of 85.18% and a density of 2797 ind/ha. The result shows that management of this coastal ecosystem has been carried out well and can develop other potential to support the area’s conservation function.

Authors: Rudi Subiyakto
Published: November 2023

The Blue Economy concept is an economic approach focused on sustainable management of marine resources that can be a solution to the disaster crisis in Indonesia. This study aims to evaluate public policy in the implementation of the Blue Economy concept in Indonesia to anticipate disasters. The research method used is qualitative with literature study as the main approach. The research findings show that existing policies related to the Blue Economy concept and disaster anticipation in Indonesia still need to be improved and strengthened in terms of application and coordination between sectors. The policy cycle in the Blue Economy concept is needed to formulate agendas, policy formulation, policy adoption and legitimacy, and policy assessment and evaluation. Challenges faced in the Blue Economy concept include the application of ecosystem principles, the development of environmentally friendly technology, increasing community involvement, and aligning government policies. In planning and implementing public policies in the Blue Economy concept, collaboration is needed between government, community, private sector, and academic institutions. Thus, synergy is created in building environmentally friendly economic sustainability and reducing disaster risks that impact human life and the surrounding environment.
Geometry optimisation of highly crowned gear couplings working in high misalignment applications to reduce tooth root stresses
Authors: Iñurritegui Aurea , Larrañaga Jon , Arana Aitor , Ulacia Ibai
Published: November 2023

Crowned gear couplings are mechanical components used to transmit power between misaligned rotating shafts. Their geometry is characterised by a significant longitudinal crowning to accommodate angular misalignment. Recent studies reveal that high misalignments drastically reduce the number of teeth in contact and lead to an uneven load distribution among engaged teeth. Consequently, tooth root fracture becomes a common failure mode. Current standards only address misalignment angles below 1.5°, treating applications with greater misalignments as special cases without design guidelines or stress prediction methods. This study proposes a procedure to optimize the design of crowned gear couplings working in high misalignment applications by determining tooth root stress distribution. The geometry is analytically generated, while finite element models are used to calculate the stress distribution. Experimental validation is performed using a dedicated test rig. The obtained results are very close to the ones from the numerical model, demonstrating the suitability of the method for crowned gear couplings operating under significant angular misalignments. The optimized design reduces tooth root stress by 50%, which will increase the fatigue life of the component or enable the application of higher torque values.

Currently, there is growing demand for cheap and reliable electricity production. One possible solution could be the construction of small modular fast neutrons nuclear reactors, where the reactor core cooling fluid is a suitable liquid metal. Liquid tin has significant advantages over the other potential candidates but its usage as coolant is challenging for the confining materials ensuring the nuclear safety of the future reactors. Current paper presents an investigation of structural materials stability in liquid tin with measurement of the surface tension, based on “Wilhelmy plate” method. The results are related to stability of spring steel, iron, nickel and copper, used as dipping plates as well as oxygen/liquid tin interactions when melted tin is exposed to air. The reported custom apparatus in our previous studies, was improved and its measuring capability was enhanced in order to demonstrate reliable results at low cost. Theoretical analysis is provided in order to demonstrate the reliability of the presented approach. Main results include: (1) Determination of liquid tin surface tension in case of air oxygen/tin reaction in liquid surface; (2) Investigation of measuring plate degradation and calculation of solution rate constant in case of dipped a plate made by copper; (3) Determination of Butler’s equation parameters in case of surface oxygen/tin interactions.
Flat ultrafiltration PAN/BNE membranes with temperature-responsive performance obtained by modification with “smart” PVA copolymer
Authors: Miteva Мilena , Christova Darinka
Published: November 2023

The ultrafiltration (UF) composite polyacrylonitrile (PAN)/ butadiene–acrylonitrile elastomer (BNE) membrane obtained by the phase inversion method was modified with temperature sensitivity by physicochemical immobilization of hydrophobically modified poly(vinyl alcohol) (HMPVA). HMPVA was prepared by partial acetalization of poly(vinyl alcohol) (PVA) with a molar mass of 75000 g/mol, resulting in a temperature-sensitive copolymer with a phase transition temperature (Ttr) of 40.2oC. Modification of the membranes was performed by introducing aqueous HMPVA solutions of different concentrations into the membrane structure, followed by its immobilization by cross-linking with glutaraldehyde. The composition, technological and structural characteristics of the membranes before and after the modification were investigated. Scanning electron microscopy (SEM) and barodynamic determinations were used in the typical UF operating pressure range (0–0.5 MPa), evaluating permeability (J, l/m2.h) and rejection (R, %) of water and albumin as a calibrant (molecular mass ~76 kDa). Temperature-sensitive HMPVA in the membrane structure optimizes the energy and material efficiency of the membrane process, including membrane service life and maintenance.
Triangel oder Mahler-Hammer im Konzert von kardiovaskulären Risikofaktoren
Authors: Schettler Volker J. J.
Published: November 2023

Wer einmal die 6. Sinfonie (1903/1904) von Gustav Mahler hört, wird sicherlich im 4. Satz dieses Musikstückes durch den Hammerschlag regelrecht erschüttert werden. Im Gegensatz dazu wirkt eine Triangel geradezu minimalistisch in der Dynamik dieses Musikstückes. Übertragen auf das Lipoprotein(a) (Lp(a)) bleibt es weiterhin unklar, wie ausgeprägt dieser Partikel bei jedem einzelnen Patienten atherosklerotische kardiovaskuläre Erkrankungen (ASCVD) induzieren kann bzw. wie ausgeprägt seine Rolle in der Pathogenese der Atherosklerose („atherosklerotisches Konzert“) tatsächlich ist.
Regionalbudget oder Selektivvertrag?
Authors: Schwarz Julian , Berghöfer Anne , von Peter Sebastian
Published: November 2023

Hintergrund Seit Einführung des § 64b SGB V im Jahr 2013 haben 22 Kliniken ein globales Behandlungsbudget (GBB) auf Basis eines psychiatrischen Modellvorhabens (MV) verhandelt. An der Budgetbildung sind einzelne, mehrere oder alle in einer Versorgungsregion vertretenen Krankenkassen beteiligt und je nach Standort wurden unterschiedliche Maßnahmen zur Förderung einer sektorenübergreifenden Leistungserbringung umgesetzt.

Ziel Es wird untersucht, ob und inwiefern der Umfang der Krankenkassenbeteiligung an MV, die Implementierungsprozesse, die Umsetzung von Versorgungsmerkmalen und die Evaluationsergebnisse zusammenhängen.

Methode Mittels systematischer Suche wurden Studien ausgewählt, die MV mit unterschiedlichen Budgetanteilen vergleichend in Bezug auf die Implementierung sowie

Ergebnisparameter untersucht haben. Um die methodische Heterogenität der Studien und die Komplexität der Fragestellung angemessen zu erfassen, wurde die integrative Übersichtsmethode genutzt.

Ergebnisse Es wurden Originalarbeiten (n = 8) aus 3 multizentrischen Studien identifiziert, wobei qualitative (n = 2) und quantitative Methoden (n = 3) sowie Mixed-Methods (n = 3) zum Einsatz kamen. Kliniken, die ihr gesamtes Budget als MV (= Regionalbudget) verhandelt haben, weisen einen durchgängig höheren Umsetzungsgrad modellspezifischer Merkmale auf, die stärker von Patienten wahrgenommen werden als Kliniken mit einem selektivvertraglichen MV. Kliniken mit Regionalbudget sind überwiegend in ländlichen, Kliniken mit partiellen GBB eher in städtischen Regionen umgesetzt.

Diskussion Die Ergebnisse stärken die Annahme eines positiven Zusammenhangs zwischen Budgetumfang sowie der Ausprägung von Struktur- und Prozessmerkmalen der Modellversorgung. Aufgrund der geringen Anzahl eingeschlossener Studien sind die Befunde als vorläufig zu betrachten.
Photothermal catalytic selective oxidation of isobutane to methacrylic acid over keggin-type heteropolyacid

Published: November 2023

Thermal and photothermal catalytic selective oxidation of isobutane to methacrylic acid (MAA) are comparatively studied over a keggin-type Cs2.9Cu0.34V0.49PMo12O40 heteropolyacid acid. An introduction of light was observed to enhance both the i-C4H10 conversion and the MAA selectivity, and consequently the MAA formate rate, particularly at low temperatures. Characterization results show that oxidation of methacrolein (MAL) to MAA is the rate-limiting step while UV light illumination promotes the oxidation of σ-bonded MAL with OH groups to σ-bonded MAA on the catalyst surface. These results demonstrate a synergistic effect of thermal catalysis and photocatalysis in selective oxidation of isobutane to MAA, which suggests photothermal catalysis as a promising strategy to catalyze the selective oxidation of higher hydrocarbons at relative mild reaction conditions.

Cardiogenic shock (CS) is a life-threatening condition characterized by a state of inadequate systemic tissue perfusion caused by cardiac dysfunction. When to implement, change, or remove the use of a temporary mechanical circulatory support (tMCS) in patients with CS is dependent on the aetiology and severity. Here, patient scenarios underlying the need to escalate, de-escalate, wean, or bridge from tMCS devices are taken into consideration by interdisciplinary heart failure and CS teams. This includes a comprehensive review of and focus on the rationale for specific device escalation and de-escalation strategies, device selection, and general management.
The Lure of Language
Authors: Gunn David M , Fewell Danna Nolan
Published: November 2023

The search for narrative significance is the scrutiny of words. The story world—with its setting, its events, its characters—is a verbal construct, a world made of words. In narrative, life is language. Words create the narrative world, and words hold the key to the significance of that world. Hence to suggest, as this chapter d,1es, that the study of narrative language can be neatly separated from the study of character or plot is misleading. We have, in fact, been working with words all along.
Aging, quantitative health status assessment and the effectiveness of medical care
Authors: Wallace Robert B , Rohre James E
Published: November 2023

In industrialized nations, the elderly consume a substantial proportion of the available health services. Yet, to the extent that various individual treatments and programmatic innovations and interventions are quantitatively evaluated, most studies are conducted on young and middle-aged adults. Evaluation of health system performance and clinical therapy requires measurement of health status. Recent advances in health status measurement of the elderly have allowed higher quality health care intervention studies, though limitations remain. Here we briefly review these methods and limitations, consider their implications for assessing health status and care needs of the community-based elderly, and examine their application to evaluating the effectiveness of selected elderly medical care programmes.

Housing for older people: the North American approach
Authors: Blackie Norman
Published: November 2023

Since the Second World War. the governments of Canada and the United States have intervened directly in the housing market to assist persons with special needs. Federal governments in Canada and the United States have employed three major forms of housing assistance: public housing, subsidized newly constructed units (built by the public and private non-profit sector), and assistance to households living in existing units in the private market. The recipients of this assistance have been low- and moderate-income households. Elderly persons have qualified for housing assistance not on the basis of age but because of low income.
