People with diabetes and chronic kidney disease (CKD) are at high risk for kidney failure, atherosclerotic cardiovascular disease, heart failure, and premature mortality. Recent clinical trials support new approaches to treat diabetes and CKD. The 2022 American Diabetes Association (ADA) Standards of Care and Kidney Disease: Improving Global Outcomes (KDIGO) 2022 Clinical Practice Guideline for Diabetes Management in CKD each provide evidence-based recommendations for management. A joint group of ADA and KDIGO representatives reviewed and developed a series of consensus statements to guide clinical care from the Standards of Care and KDIGO Guideline. The published guidelines are aligned in the areas of CKD screening and diagnosis, glycemia monitoring, lifestyle therapies, treatment goals, and pharmacologic management. Recommendations include comprehensive care in which pharmacotherapy that is proven to improve kidney and cardiovascular outcomes is layered on a foundation of healthy lifestyle. Consensus statements provide specific guidance on use of renin-angiotensin system inhibitors, metformin, SGLT2 inhibitors, GLP-1 receptor agonists, and a nonsteroidal mineralocorticoid receptor antagonist. These areas of consensus provide clear direction for implementation of care to improve clinical outcomes of people with diabetes and CKD.

O presente estudo realiza uma problematização sobre o ensino da capoeira na escola, cuja manifestação cultural e os elementos de roda e ofício dos mestres são reconhecidos como patrimônio cultural imaterial da cultura brasileira desde 2008. Foi possível observar uma desarticulação entre o reconhecimento de um patrimônio cultural com as políticas educacionais em nosso país, mesmo com a sanção de leis que amparam o ensino da capoeira na escola, como a Lei 10.639/2003 e a Base Nacional Comum Curricular. O ensino da capoeira e o conhecimento sobre sua relação histórica com o Brasil deveriam ser amplamente abordados nas escolas brasileiras, principalmente dentro da Educação Física escolar.

To selectively remove mercury(II), 2-hydroxyethyl methacrylate (HM) and 2-hydroxyethyl methacrylate/acrylamide (HM/ACR) hydrogels were synthesized using radiation. These hydrogels were used in swelling, diffusion, and binding studies. Swelling parameters for HM/ACR−Hg2+ system are higher than those of HM−Hg2+ systems. Binding of Hg2+ has been observed to be C-type for HM and L-type for HM/ACR hydrogels. Binding parameters were calculated using Freundlich, Langmuir and Henry models. Effects of Hg2+ concentration, radiation dose, ACR ratio, temperature, counter ions were investigated. Binding and swelling of HM increased with the incorporation of acrylamide. HM/ACR hydrogels absorbed only Hg2+, and did not absorb heavy metal ions.

Ecologically friendly composites have been made on the basis of wood sawdust and sillylated styrene as the binder. That binder acts simultaneously as a reinforcing agent. The surface structures were studied by a scanning electron microscopy and energy dispersive X-ray microanalysis. The bending strength increases with the increase in temperature from 453 to 493 K at the constant pressure of 15 MPa. Likely we have heterogeneous reactions between active groups of triethoxysilylated styrene and sawdust, which lead to increasing of the spatial (per specific volume) concentration of chemical bonds. Impact viscosity increases in the same temperature range from 14.6 to 25.8 kJ/m2. Water absorption determined after 3 and 24 h varies over a wide range in the function of the composition. The lowest value is 4.1 wt% water after 24 h

Phenomena of remote interaction in intergel systems polymethacrylic acid hydrogel – poly-4-vinylpyridine hydrogel (hPMAA-hP4VP) and polymethacrylic acid hydrogel – poly-2-methyl-5-vinylpyridine hydrogel (hPMAA-hP2M5VP) have been studied. It was found that there is a decrease of specific electric conductivity, pH and swelling degree of PMAA, P4VP, P2M5VP hydrogels during lanthanum ions sorption by the intergel systems. Significant increase of sorption properties (up to 30 %) in intergel systems comparatively with individual hydrogels of PMAA, P4VP, P2M5VP points to the fact of high ionization during mutual activation of the polymers. Maximum sorption of lanthanum ions occurs at the ratios of 17%hPMAA:83%hP4VP and 50%hPMAA:50%hP2M5VP. Data on obtained IR spectra evidence to the sorption of the rare-earth metal by these intergel systems. The obtained results show a significant importance of possible application of intregel systems based on rare-crosslinked polymer hydrogels of acid and basic nature for creation of new innovative sorption technologies in hydrometallurgy.

The Neutral Red (NR) has been investigated as a corrosion inhibitor for carbon steel (C-steel) in 1M perchloric acid using a weight loss method and theoretical calculations based on density functional theory (DFT). The obtained results revealed that NR is an effective inhibitor and its inhibition efficiency increases with the increasing concentration to attain 89.50 % at 5•10-3 M at 293 K. The thermodynamic parameters as enthalpy, entropy and Gibbs free energy for both dissolution and adsorption processes are calculated and discussed. Moreover, the free energy of adsorption showed that the corrosion inhibition takes place by a spontaneous physicochemical adsorption of inhibitor molecules on the C-steel surface. The results show that the calculated values of the quantum chemical parameters indicate a possible existing link between the effectiveness of the inhibitor and its electronic properties.

The deviation of density and viscosity values of oil mixtures from those calculated according to the additivity rule has been examined. Mathematical models have been developed for determining the properties of mixtures with different compositions taking into account the group composition of the source components. Mixtures containing components with a high content of alkanes and a low content of arenes have been found to be characterized by extreme deviations of density towards the maximum and kinematic viscosity towards the minimum. The created models were validated and compared with existing methods of describing the oil physicochemical properties. An approach to the creation of optimal from a technological point of view formulation for compounding oil of different types is proposed.

The oxidized bitumen produced at the Ukrainian refinery was modified with maleic anhydride. The process temperature was proved to have the most significant effect on modification. The chemical interaction of maleic anhydride with the components of oxidized bitumen was confirmed. At low temperatures (up to 403 K) the chemistry of the modification process is another than chemistry of the process carried out at high temperatures. The structures of the modified bitumen were established at different process temperatures (403, 423 and 443 K) using FTIR spectroscopy. A thin film heating at 436 K (RTFOT method) was performed for the bitumen under study. It was found that for bitumen modified at 403 K, the formed structure is destroyed after heating by RTFOT, which is confirmed by a decrease in the softening point of the bitumen. The FTIR spectra of the original oxidized bitumen and bitumen modified with maleic anhydride at 403 and 443 K were recorded after the RTFOT heating process. Based on the obtained data, the structural transformations that occurred during heating were established.

Chemical composition of sugar cane vinasse (Tucumán, Argentina) was studied finding high concentration of organic compounds. Phenolic compounds were partially characterized, finding mostly flavonoids, anthocyanins, as well as resorcinol and ferulic acid derivatives. Adsorption isotherms of phenolic compounds and total organic compounds were measured on four commercial activated carbons with different physical and chemical properties at two temperatures. The isotherm shape depends on the type of carbon and the adsorption capacity is enhanced as temperature increases. Enthalpies of the adsorption process were estimated, revealing that the adsorption of organic compounds is a chemisorption process, while the adsorption of phenolic compounds is a physisorption process on three of the tested carbons and a chemisorption process on the other one (CONCARBO).

Through powder techniques and in situ solid state reactions, a refractory cement CaAl2O4-based was fabricated, using CaCO3 extracted from chicken eggshells and Al as precursor materials. To reduce the particle size and achieve a homogeneous mixture, the powders were subjected to high-energy milling in a planetary mill. The powders resulting from the grinding were compacted to form cylindrical tablets. These samples were pressureless sintered in air. A particle size distribution analysis indicates that they were obtained from the grinding particles ranging in size from nanometers to 2 microns. Differential thermal analysis indicates that the decomposition of CaCO3 begins at 953 K and ends at 1073 K, a situation confirmed by X-ray diffraction analysis, the latter also indicating that the formation of the CaAl2O4 crystalline phase is completed at 1773 K. The microstructure observed by scanning electron microscope shows equiaxial grains in the form of flakes and sizes from 1 to 2 microns. The average density and hardness of the material was 3.08 g/cm3 and 430 HV, respectively. With regard to thermal shock tests, the material showed cracks from cooling with temperature gradients of 873 K.

Ormanların iklim değişikliğindeki rolünün toplum tarafından daha iyi anlaşılmasını sağlayacak çalışmalara ihtiyaç vardır. Bunun için medya önemli bir araçtır. Bu çalışma; iklim değişikliğiyle ormanlar ve ormansızlaşma arasındaki ilişkiyi medya aracılığıyla ortaya koymak ve bu haberlerin yeterliliğini sorgulamak amacıyla yapılmıştır. Bu amaç doğrultusunda; Türkiye’de seçilen altı gazetenin internet sitelerinde yer alan küresel iklim değişikliği ile ilgili haberlerin, Ocak 2009-Aralık 2018 tarihleri arasındaki 10 yıllık süreçte yıllar içindeki dağılımı ve bu haberlerdeki ormansızlaşmayla iklim değişikliği arasında kurulan ilişkiler incelenmiştir. Bulgulara göre; iklim değişikliği haberlerinin son yıllarda artış eğilimi içerisinde olduğu, fakat bu haberler içinde; “Orman, ağaç, bitki, biyolojik çeşitlilik, ormansızlaşma, yeşil alan vb.” haberlerin oranının sadece %12,4 oranında yer aldığı ortaya çıkmıştır. Ormanları veya ormansızlaşmayı ilişkilendiren haberlerin medyada yeterince yer bulmadığı, bundan öte sadece medyanın değil, dernek, vakıf ve platformlar ile uzman ve akademisyenlerin de ormanlarla iklim değişimi ilişkisini yeterince kuramadığı veya medya ve kamuoyuyla pek paylaşmadığı düşüncesine varılmıştır.
Türkiye ve Katar’ın Orman Ürünleri Ticareti Üzerine Bir Değerlendirme

Published: October 2022

Ekonomik zenginliği ile Katar, dış ticarette Orta Doğu’nun en önemli ülkeleri arasında yer alır. 2017 yılında bölge ülkelerinden Suudi Arabistan, Birleşik Arap Emirlikleri, Bahreyn ve Mısır Katar’a bazı ambargolar uygulamaya başlamış ve bu dönemde Katar diplomatik ve siyasi hayatta yalnız bırakılmıştır. Bu ambargolar sırasında Türkiye’nin Katar’ın yanında tavır sergilemesi, son 20 yıl içinde güçlenen Katar ile Türkiye ilişkisini pekiştirmiştir. Bu çalışmanın amacı Türkiye ile Katar’ın her geçen gün güçlenen ekonomik ve siyasi ilişkisinin orman ürünleri ticaretini nasıl etkilediğini incelemektir. Orman varlığına sahip olmayan Katar, ekonomik zenginliği ile kısmen hammadde, çoğunlukla da mamul ve yarı mamul ithalatına da meyillidir. Mevcut literatür ve güncel istatistiklerin incelenip yorumlanması ile gerçekleştirilen bu çalışma sonucunda, 2017 Körfez Krizi’nin Türkiye’nin Katar’a yönelik toplam genel ihracatında ortalama %44’lük bir artışa etki ettiği görülür. Genel ihracat kategorisindeki bu artışın orman ürünleri sanayine yansımasına bakıldığında ise mobilya hariç, mantar ve ahşap eşya kategorisinde %211’lik, ağaç ve ahşap eşya kategorisinde %353, mobilya kategorisinde ise %108’lik bir artışa neden olduğu görülmektedir. 2017 Körfez Krizi koşullarının Katar ile olan işlenmiş ve mamul düzeydeki katma değeri yüksek mobilya ihracatı kategorisinde artışa neden olduğu gözlenmiştir. Mevcut krizin sona erdiği şu günlerden sonra ise ihracattaki artışın, siyasi otoritenin Katar ile ilişkilerinin seyrine bağlı olmak kaydıyla, artarak devam edeceği tahmin edilebilir.

Published: October 2022

У роботі запропоновано ієрархічно-ітеративний метод кластеризації квазіперіодичного сигналу, що базується на алгоритмі клонального відбору, підвищує швидкість та точність кластеризації. Попередньо проводиться перетворення зразків (квазіперіодичних ділянок) цього сигналу до єдиного амплітудно-часового вікна на основі зсуву та масштабування за часом і амплітудою, лінійною інтерполяцією та дискретизацією за часом. У результаті проведеного аналізу сучасних методів кластеризації квазіперіодичних сигналів встановлено, що більшість із них має один або кілька з таких недоліків: невідома точна кількість кластерів; чутливість до початкових значень центроїдів кластерів; низька ймовірність кластеризації; низька швидкість кластеризації; порівняння ділянок сигналу, що мають лише однаковий розмір; порівняння лише бінарних сигналів. Тому актуальною є розробка методу перетворення квазіперіодичного сигналу й ієрархічно-ітеративного методу кластеризації на основі алгоритму клонального відбору. Це забезпечить підвищення ефективності аналізу структури квазіперіодичного сигналу при проведенні обробки цифрових даних в інтелектуальних комп’ютерних системах ідентифікації особистості, технічної і медичної діагностики, ана-лізу мережевого трафіку тощо. Наведено порівняння запропонованого авторами методу й існуючих методів кластеризації, при цьому параметр клонування α=0.1, параметр мутації β=2.5, кількість замінних антитіл d=0.2|H|. Кластеризація проводилася на квазіперіодичних звуках мовлення, виголошених різними дикторами. Запропоновано метод перетворення квазіперіодичного сигналу, який перетворює зразки (квазіперіодичні ділянки) цього сигналу до єдиного амплітудно-часового вікна, за допомогою зсуву й масштабування за часом і амплітудою, інтерполяцією та дискретизацією. Це дозволяє порівнювати зразки сигналу різної довжини та з різним розмахом амплітуд. Створено метод кластеризації квазіперіодичного сигналу на основі ієрархічно-ітеративного підходу й алгоритму клонального відбору, що зменшує чутливість до початкових значень центроїдів кластерів за рахунок випадкового пошуку та забезпечує адаптивне налаштування кількості кластерів за рахунок ієрархічного підходу, а також підвищує ймовірність кластеризації до 0.98.

CREDIT DEFAULT SWAPS AND BANK SAFETY
Authors: Brigida Matt
Published: October 2022

In this analysis we find evidence that credit default swap (CDS) purchasesincrease bank safety. Specifically, we show banks which were net buyers ofCDS had smaller increases in loan loss reserves in response to the COVID-19crisis. Previous research had speculated that bank CDS purchases causedincreased risk-taking by banks which offset the effect of the hedge. This anal-ysis contributes to this literature on the effect of hedging on bank risk takingand capital structure. Moreover, since our results are consistent with CDSbeing effectively used to hedge, our results have implications for systemicrisk.
Exploring potential drivers of innovation-related activities in Poland: evidence from Polish business clusters
Authors: Kuczewska Joanna , Tomaszewski Tomasz
Published: October 2022

Research background: Innovations are introduced by competitive companies. One of the most common methods, increasingly used by companies, is organizing clusters or cluster initiatives operating within a specialized sector, competing with each other, exploiting the potential of cooperation and its impact on creating new business ideas. However, these efforts could be unviable due to the lack of an effective leader of the group. One should underline a crucial role of the leader in such an organized network, since the leader makes improvements and takes initiatives for all the network and its partners. These concepts prompt us to undertake the research on the role of clusters? characteristics on enhancing willingness to innovate in general. This study aims to point out the main characteristics of clusters and to investigate their impact on companies? innovativeness. The main problem to address is the magnitude of specific effects that might boost introducing new solutions in firms? networks.
Purpose of the article: The purpose of this study is to investigate the impact of factors describing cluster environment (characteristics like cooperation within clusters and beyond them, incentives of a leader, and localization factors) that might affect the innovativeness of companies.
Methods: The authors collected data using questionnaire. This type of primary source enables the authors to construct a model consisting of latent variables such as incentives of coordinator of cluster or cluster initiative, cooperation of firms with local authorities, cooperation between entrepreneurs, or localization. The results are subject to the Structural Equation Modelling (SEM) analysis.
Findings & value added: The conducted analysis leads to several findings. Firstly, incentives provided by the cluster coordinator enable companies to increase the willingness to introduce innovations in general. Secondly, however, the influence of other cluster characteristics on the propensity to innovate for firms functioning within specific Polish business clusters is scant. These findings point to the fact that actions leading to assign the official coordinator of a cluster need to be done, as it should result in better flow of knowledge, more symmetric information among companies within cluster, and more productive and innovative way of functioning firms in general. Regarding innovation clusters (and regional innovation systems), these actions need to be supported by forming policy on regional level, because effective clusters would induce more competitive regional economy in long-term scenario.

The inhibitory effect of α-amylase enzyme from fraction and isolate of mareme leaves (Glochidion arborescens Blume.)
Authors: Ambarsari Niati , Haryoto
Published: October 2022

Mareme leaves (Glochidion arborescens Blume) is a plant that has potential as an antidiabetic agent. A previous study reported that ethanol extract of Mareme leaves exhibits active inhibitory activities of α-amylase enzyme. This study aimed to determine the α-amylase enzyme inhibitory activities of fraction and isolate from Mareme leaves. The ethanol extract of Mareme leaves was fractionated by using vacuum liquid chromatography. Then, it was isolated and purified using a chromatotron, a radial chromatographic method. The fraction and isolate were assayed for α-amylase enzyme inhibitory activities. The result indicated that Mareme leaves could inhibit an active α-amylase enzyme inhibitory activity with an IC50 value of 28.262 ppm. Mareme leaves isolate has a very active inhibition (IC50 value = 21.024 ppm) comparable with acarbose, a positive control (IC50 value = 19.486 ppm). In addition, the statistical analysis using the t-test also resulted in a significant difference in average inhibition of α-amylase enzyme between fraction and isolate of Mareme leaves. The study concludes that the fraction and isolate of Mareme leaves are potential inhibitors of α-amylase enzyme in reducing calorie intake. As such, this plant extract has been proven that it could be a potential antidiabetic or anti-obesity agent to prevent or treat chronic diseases.
Modernidad y tradición en relación a la opinión ilustrada rioplatense en el contexto previo a las revoluciones hispánicas
Authors: Milano Adriana
Published: October 2022

El trabajo propone revisitar la oposición modernidad/tradición en función de algunos discursos sobre las tierras al sur de América en vísperas del inicio de las revoluciones en Hispanoamérica, que François-Xavier Guerra señala como hito en el proceso de la modernidad política. Tales escritos, insertos aún en un escenario virreinal tradicional, presentan actitudes novedosas para el momento pues otorgan indicios para ponderar la existencia de una tendencia ya impuesta a la desacralización de la autoridad, a la manera señalada por Roger Chartier para el contexto dieciochista francés, producto de la circulación de ideas. Estas manifestaciones, puestas en diálogo con la historiografía reciente sobre los lenguajes políticos y la historia de los propios letrados, constituyen una base para pensar a partir de Guerra la operatividad de la dualidad modernidad y tradición en el análisis de los procesos históricos.El análisis no pretende abordar la problemática de definir si constituían o no opinión pública, tema que excede esta presentación, sino introducir el interrogante de qué evidencian esas opiniones en términos de modernidad/tradición y si en todos los casos resulta operativa tal distinción.
Ningún hombre es una isla o cómo apreciar la trayectoria de Jorge Sappia. De laboralistas, sindicatos peronistas y gobiernos radicales
Authors: Gerbaldo Gabriel
Published: October 2022

En el marco de las reformas laborales de fin del siglo XX en la Argentina, el artículo reconstruye los vínculos que sostuvo el laboralista Jorge Jerónimo Sappia con el sindicalismo peronista de la provincia de Córdoba y el de la Nación. Para ello, recurre al método biográfico para reconocer sus lazos partidarios y obreros, y analizar su concepción del rol del sindicalismo y su vínculo con su participación política. Consideramos que su triple dependencia (sindical, laboral y radical) le permitió articular una relación virtuosa con el sindicalismo, para conformarse en una trayectoria excepcional al interior del radicalismo debido a su capacidad de construir consensos.
Great Patriotic War in Soviet and Post-Soviet Cinematography: Problems of Remediation
Authors: Igaeva K. V. , Nikolai F. V.
Published: October 2022

The article is devoted to the representations of the Great Patriotic War in Soviet and postSoviet cinematography. The study presents the comparative analysis of the heroic narrative dating back to wartime propaganda and most clearly manifested in post-war film epics, as well as the tragic narrative, which is inextricably linked with the ‘lieutenant’ prose of the Thaw-era. The changes in the images of the Soviet cinema in the Russian war films of the 2000s are considered. It is proved that these changes, found in modern series and remakes, are critically evaluated by both academic circles and youth audience. On the basis of discussions held in ten focus groups the main critical attitudes are analyzed. Particular attention is paid to the problem of remediation which consists in the predominance of visual images only outwardly copying popular Soviet films, without independent reflection on the specificity and the meaning of military experience. It is noted that the concept of remediation makes it possible to shift the focus from dissatisfaction with individual parts of films about the Great Patriotic War to the general problem of changing the media regime in modern society and to start analyzing the mechanisms of its functioning.
Blending in Internet Communication: Linguistic and Creative Aspect (“VKontakte” Social Network)
Authors: Kasperova L. T. , Smirnova N. V.
Published: October 2022

Network blends, occasional neoplasms posted by users of the social network VKontakte under the hashtag #Slovarevo, are studied in a linguo-creative aspect. The main provisions of the theory of blending are formulated as a way of game word formation, which has become widespread in the modern communicative space in general and in the Internet environment in particular. The cognitive foundations of linguo-creativity of blending and the basic principles of conceptual integration that ensure the effective functioning of blends are determined. Structural types of blends are identified, reflecting the main formal methods of constructing contaminants in the network space. The predominance of haplological blends in the illustrative material, inheriting the original words in full and facilitating the decoding of contaminants, has been established. The main mechanisms of the language game based on blending are analyzed, reflecting the high level of metalinguistic reflection of the users of the social network “Vkontakte” involved in punning word formation. Linguistic and creative activity in the Internet environment is characterized in terms of interactivity, interaction between the addresser and the addressee. Cases of communicative failures in the interpretation of blends in the absence of contextual support and the possibility of discursive deployment of their semantics are considered. The implementation of the linguo-creative potential of network blends was assessed based on the triad “forgetive — creative — pseudo-creative”.
Anti-Easter Story by Ivan Bunin “Mowers” (structure, system of Images, “Russian Idea”)
Authors: Bogdanova O. V. , Liu Minjie
Published: October 2022

A new interpretation of I. Bunin’s story “Mowers” (1921) is proposed. If Bunin’s traditionally “short” story is considered by researchers as a realization of the theme of the Motherland, love for the lost paradise on Earth, admiration and glorification of the Russian people, the work reveals other, essentially opposite intentions of Bunin’s text. It is shown that summing up the results of the first year of emigration formed complex and contradictory thoughts about Russia and its people in Bunin’s mind. It is shown that while recreating in the story what seems to be an uncomplicated memory of the meeting with the mowers and expressing delight over their heart-wrenching song, in fact Bunin is building a complex multi-tiered narrative system. It is noted that in this system, the outer layer of the narrative (a long-standing meeting with the mowers) is crowded by today’s reflection of exiled emigrants (Paris, 1921) and is symbolized by folklore ideas about fairy-tale Russia and its primitive mythology. It is proved that the intention of the author-narrator is focused not on admiration for the past and the lost (traditional perspective), but on antagonism and rejection of the old fairy tale, which, according to Bunin of the 1920s, has come to an end. The central motives of the story are rethought, the semantic recoding of the title image of the mowers is traced.
