Adipoz doku hem enerji deposu hem de adipokinler olarak adlandırılan biyolojik olarak önemli çok sayıda molekülü salgılayan aktif bir endokrin organ olarak işlev görmektedir. Adipokinlerin üreme fonksiyonlarının düzenlenmesinde yer aldığı kanıtlanmıştır ve tanımlanan ilk adipokin leptindir. Son yıllarda yapılan araştırmalar, leptinin beyine giden enerji depolarının miktarının yalnızca yağ dokusundan türetilen bir habercisi olmadığını, aynı zamanda iltihaplanma, anjiyogenez, hematopoez, bağışıklık fonksiyonu ve üreme gibi bir dizi farklı fizyolojik süreç için çok önemli bir hormon/sitokin olduğunu göstermektedir. Adiposit kaynaklı bir hormon olan leptin, özellikle ergenlik ve üreme döneminde vücutta çok sayıda fizyolojik ve metabolik fonksiyonda önemli rol oynamaktadır. Leptin, merkezi hipotalamik etkilerinin yanı sıra, testisler de dahil olmak üzere birçok periferik organda (mide, iskelet kası, hipofiz hücreleri, plasenta) etki göstermektedir ve hem erkek üreme hem de dişi üreme işlevinde düzenleyici bir role sahiptir. Leptin normal üreme işlevi için gereklidir, ancak fazla miktarda bulunduğunda üreme sistemi üzerinde zararlı etkileri olabilir. Non-obstrüktif azoospermi, oligozoospermi ve oligo-asteno-teratozoospermi dahil olmak üzere testiküler parankimi etkileyen bozuklukları olan infertil erkeklerin yüksek leptin konsantrasyonlarına sahip olduğu bilinmektedir. Literatürde yapılan son çalışmalar, hipotalamik-hipofizeal-gonadal (HPG) ekseni, androjen regülasyonu ve sperm üretimi ile leptin ve infertilite arasında güçlü bir ilişki olduğunu öne sürmektedir. Yapılan bu çalışmalardan yola çıkarak, leptin fazlalığı, eksikliği veya direnci durumlarının anormal üreme işlevi ile ilişkili olabileceğini söylemek mümkündür. Ayrıca, yüksek leptinin neden olduğu bu anormallikler artan oksidatif stres ile de ilişkilendirilmiştir. Eğer ki leptin ve üreme arasındaki ilişki tam olarak anlaşılabilirse, hem erkek hem de kadın infertilitesi için gelecekte hedeflenen tedavilere ışık tutabilecektir. Bu derleme leptin ile fertilite arasındaki ilişkiye odaklanmaktadır.

A implementação de tecnologias de informação (TI) na gestão hospitalar tem se mostrado fundamental para aprimorar a eficiência e a qualidade da assistência prestada aos pacientes. Este estudo teve como objetivo analisar os impactos dessa implementação nesses dois importantes aspectos da gestão hospitalar. A revisão bibliográfica foi realizada com base em artigos científicos e revisões relevantes nas áreas de gestão hospitalar, tecnologia da informação em saúde e qualidade assistencial. Os resultados obtidos revelaram que a adoção de sistemas de informação hospitalar promove uma série de benefícios, incluindo a melhoria da eficiência operacional, a redução de erros, a otimização dos fluxos de trabalho e o aumento da segurança do paciente. Os sistemas de registro eletrônico de saúde (EHR) são particularmente destacados por sua capacidade de armazenar, recuperar e compartilhar informações de saúde de forma rápida e precisa entre os profissionais de saúde, resultando em uma assistência mais integrada e coordenada. Além disso, observou-se que as tecnologias de informação são essenciais para promover a qualidade assistencial, fornecendo suporte à decisão clínica, facilitando a coleta e análise de dados clínicos, e permitindo a implementação de protocolos baseados em evidências. Isso contribui para a redução de eventos adversos, a melhoria da conformidade com práticas clínicas recomendadas e a promoção de uma assistência mais segura e eficaz. As discussões apontaram que, embora as tecnologias de informação ofereçam inúmeros benefícios, sua implementação pode enfrentar desafios significativos, como custos elevados, resistência à mudança por parte dos profissionais de saúde e questões relacionadas à interoperabilidade de sistemas. Portanto, estratégias eficazes de gerenciamento de mudanças e investimentos adequados em infraestrutura e capacitação são essenciais para garantir o sucesso da implementação. Em conclusão, este estudo destaca o papel crucial das tecnologias de informação na gestão hospitalar, enfatizando seus impactos positivos na eficiência operacional e na qualidade assistencial. A implementação bem-sucedida dessas tecnologias requer um compromisso contínuo com o desenvolvimento e aprimoramento dos sistemas, bem como uma abordagem centrada no paciente e na melhoria contínua dos processos de assistência.
Forest-floor respiration, N2O fluxes, and CH4 fluxes in a subalpine spruce forest: drivers and annual budgets

Published: April 2024

Abstract. Forest ecosystems play an important role in the global carbon (C) budget by sequestering a large fraction of anthropogenic carbon dioxide (CO2) emissions and by acting as important methane (CH4) sinks. The forest-floor greenhouse gas (GHG; CO2, CH4, and nitrous oxide (N2O)) flux, i.e., from soil and understory vegetation, is one of the major components to consider when determining the C or GHG budget of forests. Although winter fluxes are essential to determine the annual C budget, only very few studies have examined long-term, year-round forest-floor GHG fluxes. Thus, we aimed to (i) quantify seasonal and annual variations of forest-floor GHG fluxes; (ii) evaluate their drivers, including the effects of snow cover, timing, and amount of snowmelt; and (iii) calculate annual budgets of forest-floor GHG fluxes for a subalpine spruce forest in Switzerland. We measured GHG fluxes year-round during 4 years with four automatic large chambers at the ICOS Class 1 Ecosystem station Davos (CH-Dav). We applied random forest models to investigate environmental drivers and to gap-fill the flux time series. The forest floor emitted 2336 g CO2 m−2 yr−1 (average over 4 years). Annual and seasonal forest-floor respiration responded most strongly to soil temperature and snow depth. No response of forest-floor respiration to leaf area index or photosynthetic photon flux density was observed, suggesting a strong direct control of soil environmental factors and a weak, or even lacking, indirect control of canopy biology. Furthermore, the forest floor was a consistent CH4 sink (−0.71 g CH4 m−2 yr−1), with annual fluxes driven mainly by snow depth. Winter CO2 fluxes were less important for the CO2 budget (6.0 %–7.3 %), while winter CH4 fluxes contributed substantially to the annual CH4 budget (14.4 %–18.4 %). N2O fluxes were very low (0.007 g N2O m−2 yr−1), negligible for the forest-floor GHG budget at our site. In 2022, the warmest year on record with below-average precipitation at the Davos site, we observed a substantial increase in forest-floor respiration compared with other years. The mean forest-floor GHG budget indicated emissions of 2319 ± 200 g CO2 eq. m−2 yr−1 (mean ± standard deviation (SD) over all years), with respiration fluxes dominating and CH4 offsetting a very small proportion (0.8 %) of the CO2 emissions. Due to the relevance of snow cover, we recommend year-round measurements of GHG fluxes with high temporal resolution. In a future with increasing temperatures and less snow cover due to climate change, we expect increased forest-floor respiration at this subalpine site modulating the carbon sink of the forest ecosystem.

Abstract. Climate reconstructions of the last millennium rely on networks of high-resolution and well-dated proxy records. This study presents age-at-depth data and preliminary results from the new Mount Brown South (MBS) ice cores, collected at an elevation of 2084 m on the boundary of Princess Elizabeth Land and Kaiser Wilhelm II Land in East Antarctica. We show an initial analysis of the site meteorology, mean annual chemical species concentrations and seasonal cycles, including the identification of a seasonal cycle in fluoride concentrations. The annually resolved chronologies were developed from the chemistry data using a site-specific layer-counting methodology that employed seasonally varying trace chemical species and stable water isotopic ratios, combined with alignment to known volcanic horizons. The uncertainty in the determination of annual horizons via layer counting was also quantified. The chronologies developed include the “Main” 295 m record spanning 1137 years (873–2009 CE) and three surface cores spanning the most recent 39–52 years up to the surface age at the time of drilling (austral summer 2017/2018). Mean annual trace chemical concentrations are compared to the Law Dome ice core (located 1130 km east of the Mount Brown South site) and discussed in terms of atmospheric transport. The MBS chronologies presented here – named MBS2023 – will underpin the development of new palaeoclimate records spanning the past millennium from this under-represented region of East Antarctica.
Unveiling hydrological dynamics in data-scarce regions: experiences from the Ethiopian Rift Valley Lakes Basin

Published: April 2024

Abstract. The hydrological system of the Rift Valley Lakes in Ethiopia has recently experienced changes over the past 2 decades. Potential causes for these changes include anthropogenic, hydro-climatic, and geological factors. The main objective of this study was to utilize an integrated methodology to gain a comprehensive understanding of the hydrological systems and potential driving factors within a complex and data-scarce region. To this end, we integrated a hydrologic model, change point analysis, indicators of hydrological alteration (IHA), and a bathymetry survey to investigate hydrological dynamics and potential causes. A hydrologic model (the Soil and Water Assessment Tool Plus, SWAT+) was parameterized for the gauged watersheds and extended to the ungauged watersheds using multi-site regionalization techniques. The SWAT+ model performed very well to satisfactorily for daily streamflow in all watersheds with respect to the objective functions of the Kling–Gupta efficiency (KGE), the Nash–Sutcliffe efficiency (NSE), and percent bias (PBIAS). The findings reveal notable changes in lake inflows and lake levels over the past 2 decades. Lake Chamo experienced an increase in area of 30.1 km2 (9.5 %), an increase in depth of 4.4 m (30.9 %), and an increase in volume of 7.8×108 m3 (27.2 %). In contrast, Lake Abijata witnessed an extraordinary 68 % decrease in area and a depth decrease of 1.6 m (37.2 %). During the impact period, the mean annual rainfall experienced a decrease of 6.5 % and 2.7 % over Lake Abijata and Lake Chamo, respectively. Actual evapotranspiration decreased by 2.9 % in Lake Abijata but increased by up to 4.5 % in Lake Chamo. Surface inflow to Lake Abijata decreased by 12.5 %, while Lake Chamo experienced an 80.5 % increase in surface inflow. Sediment depth in Lake Chamo also increased by 0.6 m (4.2 %). The results highlight that the changing hydrological regime in Lake Chamo is driven by increased surface runoff and sediment intrusion associated with anthropogenic influences. The hydrological regime of Lake Abijata is affected by water abstraction from feeding rivers and lakes for industrial and irrigation purposes. This integrated methodology provides a holistic understanding of complex data-scarce hydrological systems and potential driving factors in the Rift Valley Lakes in Ethiopia, which could have global applicability.
Characteristics of debris-flow-prone watersheds and debris-flow-triggering rainstorms following the Tadpole Fire, New Mexico, USA

Published: April 2024

Abstract. Moderate- or high-severity fires promote increases in runoff and erosion, leading to a greater likelihood of extreme geomorphic responses, including debris flows. In the first several years following fire, the majority of debris flows initiate when runoff rapidly entrains sediment on steep slopes. From a hazard perspective, it is important to be able to anticipate when and where watershed responses will be dominated by debris flows rather than flood flows. Rainfall intensity averaged over a 15 min duration, I15, in particular, has been identified as a key predictor of debris flow likelihood. Developing effective warning systems and predictive models for post-fire debris flow hazards therefore relies on high-temporal resolution rainfall data at the time debris flows initiate. In this study, we documented the geomorphic response of a series of watersheds following a wildfire in western New Mexico, USA, with an emphasis on constraining debris flow timing within rainstorms to better characterize debris-flow-triggering rainfall intensities. We estimated temporal changes in soil hydraulic properties and ground cover in areas burned at different severities over >2 years to offer explanations for observed differences in spatial and temporal patterns in debris flow activity. We observed 16 debris flows, all of which initiated during the first several months following the fire. The average recurrence interval of the debris-flow-triggering I15 is 1.3 years, which highlights the susceptibility of recently burned watersheds to runoff-generated debris flows in this region. All but one of the debris flows initiated in watersheds burned primarily at moderate or high soil burn severity. Since soil hydraulic properties appeared to be relatively resilient to burning, we attribute reduced debris flow activity at later times to decreases in the fraction of bare ground. Results provide additional constraints on the rainfall characteristics that promote post-fire debris flow initiation in a region where fire size and severity have been increasing.

Abstract. Coastal flood risk is a serious global challenge facing current and future generations. Several disaster risk reduction (DRR) measures have been posited as ways to reduce the deleterious impacts of coastal flooding. On a global scale, however, efforts to model the future effects of DRR measures (beyond structural) are limited. In this paper, we use a global-scale flood risk model to estimate the risk of coastal flooding and to assess and compare the efficacy and economic performance of various DRR measures, namely dykes and coastal levees, dry-proofing of urban assets, zoning restrictions in flood-prone areas, and management of foreshore vegetation. To assess the efficacy of each DRR measure, we determine the extent to which it can limit future flood risk as a percentage of regional GDP to the same proportional value as today (a “relative risk constant” objective). To assess their economic performance, we estimate the economic benefits and costs of implementing each measure. If no DRR measures are implemented to mitigate future coastal flood risk, we estimate expected annual damages to exceed USD 1.3 trillion by 2080, directly affecting an estimated 11.5 million people on an annual basis. Low- and high-end scenarios reveal large ranges of impact uncertainty, especially in lower-income regions. On a global scale, we find the efficacy of dykes and coastal levees in achieving the relative risk constant objective to be 98 %, of dry-proofing to be 49 %, of zoning restrictions to be 11 %, and of foreshore vegetation to be 6 %. In terms of direct costs, the overall figure is largest for dry-proofing (USD 151 billion) and dykes and coastal levees (USD 86 billion), much more than those of zoning restrictions (USD 27 million) and foreshore vegetation (USD 366 million). These two more expensive DRR measures also exhibit the largest potential range of direct costs. While zoning restrictions and foreshore vegetation achieve the highest global benefit–cost ratios (BCRs), they also provide the smallest magnitude of overall benefit. We show that there are large regional patterns in both the efficacy and economic performance of modelled DRR measures that display much potential for flood risk reduction, especially in regions of the world that are projected to experience large amounts of population growth. Over 90 % of sub-national regions in the world can achieve their relative risk constant targets if at least one of the investigated DRR measures is employed. While future research could assess the indirect costs and benefits of these four and other DRR measures, as well as their subsequent hybridization, here we demonstrate to global and regional decision makers the case for investing in DRR now to mitigate future coastal flood risk.

Abstract. Surface water flooding (SWF) is a severe hazard associated with extreme convective rainfall, whose spatial and temporal sparsity belie the significant impacts it has on populations and infrastructure. Forecasting the intense convective rainfall that causes most SWF on the temporal and spatial scales required for effective flood forecasting remains extremely challenging. National-scale flood forecasts are currently issued for the UK and are well regarded amongst flood responders, but there is a need for complementary enhanced regional information. Here we present a novel SWF-forecasting method, FOREWARNS (Flood fOREcasts for Surface WAter at a RegioNal Scale), that aims to fill this gap in forecast provision. FOREWARNS compares reasonable worst-case rainfall from a neighbourhood-processed, convection-permitting ensemble forecast system against pre-simulated flood scenarios, issuing a categorical forecast of SWF severity. We report findings from a workshop structured around three historical flood events in Northern England, in which forecast users indicated they found the forecasts helpful and would use FOREWARNS to complement national guidance for action planning in advance of anticipated events. We also present results from objective verification of forecasts for 82 recorded flood events in Northern England from 2013–2022, as well as 725 daily forecasts spanning 2019–2022, using a combination of flood records and precipitation proxies. We demonstrate that FOREWARNS offers good skill in forecasting SWF risk, with high spatial hit rates and low temporal false alarm rates, confirming that user confidence is justified and that FOREWARNS would be suitable for meeting the user requirements of an enhanced operational forecast.
Bicycle use in the university community: Empirical analysis using MobiCampus-UdL data (Lyon, France)
Authors: Havet Nathalie , Bouzouina Louafi
Published: April 2024

Promoting sustainable mobility systems by encouraging the use of the bicycle as a transport mode is now a public policy objective. This political will is also pursued in France where the modal share of cycling is relatively low. However, young people and those with a high level of human capital, such as members of the university community, are observed to be more advanced in their adoption of cycling. An understanding of how cycling is used by university students and staff would therefore help to inform public decision-making and support more efficient targeted policies to develop this mode of transport. Using original data from the MobiCampus-UdL project, the aim of this article is to analyze the determinants of bicycle use by the university community at the University of Lyon, France. Two multivariate logistic regression models are estimated on the subsamples of students and staff: one explaining the probability of using the bicycle as an exclusive mode of transport to get to the campus and the other explaining the probability of using the bicycle in combination with other modes. Our results suggest that while socio-demographic characteristics have little influence within our two relatively homogeneous subsamples, access to mobility resources and the spatial characteristics of the campus and place of residence are crucial. We also find that access to bicycles is an important determinant of the utilization of cycling. Given that the adoption of cycling is still very low, our findings justify policies to increase the availability of bicycles and subsidize their purchase. More specifically, our results suggest that access to a shared bike station on campus encourages the exclusive use of bicycles by students and staff but has no effect when used in combination with other modes. On the other hand, good accessibility to public transport, whether from home or from campus, does not reduce the use of bicycles by either sub-population, either exclusively or in combination. Furthermore, while living far from the city center is an obstacle to the exclusive use of the bicycles, especially for staff, it does not in any way prevent their use in combination with other modes, such as the train. These results open up new avenues for anticipating the development of intermodality between public transport and cycling.

La ciencia política y la investigación: la cuestión del método
Authors: Suárez-Cao Julieta , Sánchez-Staniak Federica
Published: April 2024

La cuestión del método en ciencia política no está exenta de debate. En el siglo XX se argumentaba la preeminencia de los análisis cuantitativos por sobre los cualitativos, una visión que se empieza a desmitificar en las últimas décadas gracias a trabajos como los de Brady y Collier (2004), y Goertz y Mahoney (2012). Partiendo de desmontar la jerarquía entre los métodos que es herencia de una visión clásica de los estudios en ciencia política, este artículo propone lineamientos para abordar decisiones metodológicas en los trabajos de investigación. Se presentan inicialmente las diversas perspectivas metodológicas utilizadas por la investigación en ciencia política. Se propone poner en el foco en no solamente en la pregunta de investigación, sino también en las respuestas tentativas que estas pueden suscitar, de manera de subrayar la importancia de la teoría y su congruencia con los postulados metodológicos. Si bien la propuesta analítica es secuencial, el artículo ofrece matices relacionados con la experiencia práctica concreta en la que se entremezclan las diferentes etapas de la investigación.
El pecado de Facebook: Artesanía digital en una diáspora romaní

Published: April 2024

En un estudio sobre redes digitales en una diáspora romaní procedente del occidente rumano, pudimos afinar nuestro conocimiento etnográfico del uso específico que la población estudiada hacía de las tecnologías digitales, observando que habían desarrollado «artesanías» concretas que reflejaban un modelado cultural del binomio smartphone-Facebook. Este modelado venía marcado por el temor al control-represión institucional, el correlato digital del sistema sexo-género, y un creciente papel del pentecostalismo en la gestión y valoración de Facebook. Asimismo, nuestra experiencia reveló el valor de la comprensión etnográfica para diseñar técnicas digitales de producción de datos culturalmente sensibles. Confirmamos que las respuestas a las tecnologías no son universales, dependiendo estas de los contextos socioculturales donde se generan. En este grupo, «vivir sin Facebook» puede ser difícil, pero también existe el riesgo constante de incurrir en «pecados» a través del smartphone, transgresiones que ponen en peligro vínculos familiares, religiosos y etnoculturales.
Algo que puede ser quitado: tierra, persona y despojos en Santiago del Estero (Argentina)
Authors: Fernanda Figurelli Mónica
Published: April 2024

En este artículo me baso en una investigación realizada en la provincia argentina de Santiago del Estero, con integrantes del Movimiento Campesino de Santiago del Estero-Vía Campesina. Abordo diferentes formas por medio de las cuales habitantes de zonas rurales de esa provincia, que participan del Movimiento, dan sentido a la noción de “tierra”. Me centro en dos significados destacados durante mi trabajo de campo. En uno de ellos la tierra es concebida como un bien que puede ser poseído; en el otro es simbolizada con la figura de la Madre y se observa como una entidad que contiene, alimenta y debe ser defendida. Ambos significados son diferentes entre sí, pero comunes en que proyectan una tierra cosificada. Mi intención es subrayar la centralidad que en esos modos de aprehensión tienen las expoliaciones vividas por las personas en relación con el lugar en el que habitan, lo cual abre la posibilidad de que las ideas de persona y ambiente sean experimentadas como dos entidades separadas.
Emociones policiales: sentimientos de vulnerabilidad y estrategias para afrontarlos entre policías de Madrid
Authors: García García Sergio
Published: April 2024

Los diferentes ámbitos sociales y profesionales conllevan experiencias emocionales específicas ligadas a situaciones interaccionales particulares. En este artículo me propongo analizar el repertorio emocional que experimentan los agentes de Policía. Preguntándome por las experiencias de vulnerabilidad que operan por debajo del poder policial, he revisado los materiales etnográficos procedentes de distintas investigaciones en el campo securitario y policial en Madrid en las que he participado. Entre los hallazgos, desarrollo de un lado las experiencias de vulnerabilidad más comunes en el trabajo policial, las cuales se relacionan con tres tipos de situaciones: de tensión, de presión y de juicio crítico. De otro lado, analizo las diferentes estrategias desplegadas para afrontar esa vulnerabilidad: aquellas que refuerzan el espíritu de Cuerpo y que transmutan las críticas en sentimiento de orgullo policial, y aquellas otras que implican una cierta transformación subjetiva a través de la aproximación a metodologías “blandas” propias del trabajo social y del contacto con referentes académicos.

Rhizome de l’écosystème du numérique universitaire français et nouvelle gouvernance : Mutualisation, gouvernance et numérique universitaire
Authors: Mocquet Bertrand
Published: April 2024

Nous proposons de caractériser l’organisation du numérique universitaire français, en examinant ses processus de fabrication, de fonctionnement et de gouvernance en interrogeant le concept de rhizome, développé en 1980 par Deleuze et Guattari. Par numérique universitaire français, nous entendons les technologies numériques qui sous-tendent le fonctionnement et la gestion de l’enseignement supérieur. Cet article vise à décrire les diverses formes organisationnelles observées (associations, groupements d’intérêt public, consortiums, établissements publics…), ainsi que leurs interactions, en adoptant une approche catégorielle dans une volonté de rendre intelligible cette organisation profondément organique, qui se développe de manière discrète par l’interaction des acteurs qui la composent. L’analyse de cette dynamique permet d’appréhender la complexité de l’écosystème numérique universitaire français et de comprendre comment les acteurs impliqués collaborent, interagissent et influencent l’évolution du système formant ainsi une forme de nouvelle gouvernance. En scrutant, au moyen d’entretiens menés ces deux dernières années ou d’informations récoltées de manière formelle et informelle, les mécanismes de cet écosystème, nous mettons en lumière les modes d’action des différents acteurs tels que les universités, les entreprises technologiques et les organismes publics. Cette approche offre une perspective rhizomique afin de permettre d’envisager l’évolution du numérique dans l’enseignement supérieur français.

The Role of Folic Acid in Gastric Precancerous Lesion: A Literature Review
Authors: Tanjung Yulisa , Rey Imelda , Lubis Masrul
Published: April 2024

Folic acid appears to hold promise as a potential preventive and therapeutic agent in gastric precancerous lesions. Folic acid, as an essential cofactor in DNA synthesis and methylation, plays a crucial role in maintaining genomic stability and regulating gene expression. It promotes DNA repair processes and protects against DNA damage, thereby inhibiting the initiation and progression of precancerous lesions. Moreover, folic acid acts as an antioxidant, mitigating oxidative stress and reducing inflammation in the gastric mucosa, which are key factors in the development of these lesions. Preclinical studies consistently demonstrate its protective effects against lesion development and progression, while clinical studies provide preliminary evidence for its efficacy in lesion regression or risk reduction. However, further well-designed clinical trials are needed to establish a definitive causal relationship, optimize folic acid supplementation strategies, and determine the optimal dosage and duration for gastric precancerous lesion management.

Kehadiran media sosial mengubah banyak hal. Salah satunya adalah 'Ruang Berita'. Saat ini terdapat fenomena netizen yang lebih memilih mengonsumsi berita dari akun influencer di media sosial, dibandingkan media massa dalam platform yang sama. Faktanya, media massa mempunyai kredibilitas untuk melakukan hal tersebut. Di tingkat lokal, hal ini setidaknya terlihat dari perbandingan yang sangat jauh, antara jumlah pengikut akun influencer dengan jumlah pengikut media massa di media sosial. Penelitian ini bertujuan untuk menganalisis fenomena tersebut. Untuk membuktikan benar atau tidaknya, kecenderungan netizen lebih memilih mengonsumsi berita dari influencer dibandingkan media massa di media sosial, dan mencari tahu apa saja faktor pendorong yang menyebabkannya. Metode penelitian yang digunakan adalah metode deskriptif kualitatif. Peneliti melontarkan beberapa pertanyaan kepada warganet yang diambil berdasarkan klasifikasi tertentu. Hasil survei tersebut kemudian didukung dengan pernyataan beberapa ahli di bidangnya yang relevan dengan topik yang diteliti. Hasilnya, warganet diketahui lebih memilih mengonsumsi berita di akun influencer dibandingkan media massa di media sosial. Ada beberapa faktor yang menjadi pemicunya. Diantaranya karena influencer dinilai lebih up to date dibandingkan media massa, dalam hal penyebaran berita di media sosial. Hal ini membuat influencer lebih digandrungi oleh netizen, dibandingkan media massa. Namun di sisi lain, fenomena ini juga menyisakan banyak pertanyaan yang perlu dijawab. Sebab, bagaimana influencer bisa menjadi primadona warganet dalam pemberitaan, padahal mereka tidak berkompeten dalam memproduksi dan mendistribusikan berita.

The problem of creating antimicrobial protection methods in rocket and space technology requires new approaches, in particular, the development of antibacterial coatings to protect the payload of launch vehicles. Also, in outer space outside the Earth's atmosphere, ultraviolet radiation with a wavelength of less than 280 nm (hard and vacuum ultraviolet) accelerates degradation of materials. It is relevant to create protective coatings for various materials used in space. An innovative extraction-pyrolytic method for producing oxide films containing copper, titanium and titanium oxide nanoparticles is considered. As a result, the compositions of effective antibacterial coatings with the function of protection against UV radiation have been established. The intended service and design features of the part on which the coating is applied are considered, and a flow diagram for applying an antibacterial coating to protect the internal volume of the fairing from bacteria circulating in the head of the launch vehicle is proposed. The possibilities of protection against UV radiation by applying oxide films to the outer surface of devices and rocket parts have been studied.

The influence of water content in hydraulic fluids on their viscosity and temperature properties is considered. It is substantiated that a change in the viscosity of mineral oils with a change in water content can lead to both an increase in viscosity and a decrease in it. The results of an experimental determination of the viscosity of mineral oil mixed with a seawater simulator are presented. It is indicated that models of non-Newtonian fluids can be used to describe the behavior of the mixtures under consideration.

В работе рассматривается один из классов операторов преобразования. Операторы преобразования – это известный раздел теории дифференциальных уравнений, в его рамках были получены заметные результаты для этой теории. В данной работе рассматривается круг задач для операторов преобразования Векуа – Эрдейи – Лаундеса. Эти операторы преобразования, которые были введены в работах указанных математиков, позволяют сплетать дифференциальные операторы различной природы со спектральным параметром с аналогичными дифференциальными операторами без спектральных параметров. В частности, на этом пути устанавливаются и явные формулы соответствия между решениями этих двух классов дифференциальных уравнений. Для иллюстрации метода он применяется к некоторым конкретным дифференциальным уравнениям.

Fear of movement, pain, and loss of shoulder function are the most common problems irrespective of their approach to management after proximal humeral fracture (PHF). However, it has been unclear whether there could be differences between both treatments in early clinical outcomes. It can help physiotherapists to guide in choosing treatment approaches. This study aimed to compare kinesiophobia, pain, range of motion (ROM), shoulder function, and Quality of life (QoL) in patients treated with either conservative (CT) versus surgical (ST) after PHF. In addition, it aimed to determine correlations between fear of movement and seconder outcome measures. This cross-sectional study enrolled the patients having 5-6 weeks (being permitted active movement) after being treated either CT or ST and receiving no physical therapy. Pain, passive and active ROMs, shoulder function, fear of movement, and QoL were evaluated. 42 patients were recruited. Kinesiophobia scores were similar (p=0.55) and moderate in both groups. There was a significant difference in degrees of shoulder active flexion, active and passive abduction in favor of the CT group (p=0.05, p=0.02, p=0.04, respectively). However, there was no difference between groups regarding the remaining clinical outcomes. Furthermore, kinesiophobia showed a moderate negative correlation with energy/fatigue, social functioning, and general health. These findings showed that patients treated surgically did not have more kinesiophobia, less function, and QoL before starting physiotherapy, despite having soft tissue damage and different types of fractures. However, surgically treated patients had significantly less range of motion.
