The Impact of Environmental Factors on Traits of Hedera Helix L. Vegetative Shoots
Authors: Blinkova Olena , Rawlik Katarzyna , Jagodziński Andrzej M.
Published: March 2023

Hedera helix L. is an evergreen vine native to Europe. Nowadays it is commonly recognised as an expansive species, posing danger to biodiversity of natural ecosystems. Obtaining the relationships between morphological variability, productive parameters of vegetative individuals and variations in environmental factors (on the example of the Kórnik Arboretum) is important for understanding the successful adaptation and dispersion of H. helix. Thus, the issue of our studies was to find the link between environmental factors and different traits of H. helix. We collected data on leaf length, leaf width, leaf petiole length, plant stem length, and the number of leaves per stem. We assessed values of ecological plasticity and correlation between the studied parameters. The results indicated the tolerance of ivy to wide variation in edaphic conditions. The limiting environmental factors for growth of the studied subpopulations were soil moisture and soil shade. We found large variability of leaf morphometric parameters and shoot length. Close correlation links were detected between leaf length/leaf width, leaf length/leaf petiole length, and leaf width/leaf petiole length. The length of the average leaf was a more variable parameter than the width of the leaf under different values of light intensity. Weak relationships were found between light intensity at the soil surface and plant stem length/the number of leaves per shoot. A high level of index of morphological integration of H. helix individuals and a close relationship between the quality index/subpopulation composition were established in this study. A direct relationship between light intensity and specific leaf area values was established. The value of specific leaf area decreased linearly with increasing of light intensity at the soil surface.

Tall moss turf subformation, whose developed forms are called moss banks (MB), play an important role in the structure of vegetation communities in the maritime Antarctic. In the present research, we studied the spatial distribution, moss banks thickness, area, species amount, dependence between these parameters, and species composition of the 44 MB on Galindez Island, Argentine Islands, Graham Coast. To select indicators for the monitoring of communities affected by climate change and biotic disturbance we compared the key parameters of the largest moss bank on Galindez Island (Smith moss bank) with measurements received for this moss bank 46 years ago. Galindez moss banks’ bryophyte flora included 13 species of mosses and three species of liverworts. There was no correlation between the species richness and the area of MB, but the species richness positively correlated with moss banks’ thickness. We supposed species diversity of MB depended presumably on the age of the moss bank and micro-conditions than on the area. Abundance of some moss species correlated with moss bank thickness. A comparison of results obtained in this study and in 1976, revealed an increase in the amount of brown- and black-coloured curtains of Polytrichum strictum, no significant changes in the ratio of Chorisodontium aciphyllum and a decrease in the lichen incrustation. These results show that the ratio of P. strictum’s colour morphotypes, C. aciphyllum and liverworts’ abundance can be used to evaluate the condition of MB in the long-term monitoring.

In the era of cloud service popularization, the trustworthiness of service is particularly important. If users cannot prevent the potential trustworthiness problem of the service during long-term use, once the trustworthiness problem occurs, it will cause significant losses. In order to objectively assess the cloud service trustworthiness, and predict its change, this paper establishes a special hierarchical model of cloud service trustworthiness attributes. This paper proposes corresponding management countermeasures around the model, defines the cloud service trustworthiness level, defines the cloud service trusted state based on fuzzy entropy and Markov chain, constructs the membership function of the cloud service trusted state, and realizes the assessment of cloud service trustworthiness and its change according to the prediction method of Markov chain. Through case analysis and method comparison, it shows that the method proposed in this paper is effective and feasible. This method can provide objective and comprehensive assessment data for the cloud service trustworthiness and its change, makes up the deficiency of fuzzy entropy assessment method. This research has important reference value and significance for the research of cloud service trustworthiness assessment.

Published: March 2023

Metal dusting behaviours of Fe-(10, 20, 25)Cr, Fe-20Cr-(20, 33)Ni, Fe-25Cr-20Ni (wt.%) in a Ar-33CO-7H2-7CO2-2H2O (vol.%) gas at 550℃ and 650℃ were investigated in simulating a blast furnace operating condition. Severe metal dusting and coke deposition were observed at 550℃, while no significant dusting but internal oxidation and carburization were observed at 650℃. Higher Cr and Ni contents in the alloy lowered kinetics of metal dusting at 550℃ and of carburization at both temperatures. In particular, Fe-25Cr was the only alloy exhibiting no significant metal dusting at 550℃. Increasing Cr concentration also reduced oxidation kinetics at both temperatures. Austenitic alloys were more susceptible to metal dusting and coke deposition than ferritic alloys with the same Cr content at 550℃. At 650℃, however, ferritic alloys experienced higher extents of carburization and oxidation than austenitic alloys with the same Cr concentration.

Bovine Viral Diarrhea virus (BVDV) affects cattle worldwide causing severe productive and economic loss. In this study, we investigated the subgenotypes of BVDV circulating in cattle samples from the Aysén region, an active cattle breeding area located in southern Chile. Partial amplification of the 5' untranslated region (UTR) was performed by polymerase chain reaction (PCR), and twelve samples were analyzed by Sanger sequencing and phylogenetic analysis. Eight samples were identified as belonging to BVDV-1e, three to 1-b, and one to 1-d. The phylogenetic analyses performed revealed a marked distance between these now-identified strains and those previously reported in the country. These findings support the need to continually expand the analysis of the variability of the viral phylogeny for the currently circulating BVDV strains and to update the vaccines recommended for this livestock area and surrounding areas.

Published: March 2023

Pharmaceutical product generally depends on environment controls during its storage and handling. Temperature mapping is essential and should be managed during entire product lifecycle with holistic approach. The purpose of this study was to determine the challenges during temperature mapping process in pharmaceutical product warehouses in Tanzania. The task analysis of temperature mapping process was carried out. As a result of the study, general requirements were formulated for the preparation; challenges were identified. Study shows majority of pharmaceutical workers lack of knowledge on temperature mapping, the use of local tool in temperature affecting the efficacy, safety and efficiency of the pharmaceutical product. The frequency of temperature mapping envisaged unsatisfactory. Hence, temperature mapping process in pharmaceutical industry should be recorded and reported to the manufacturer for further investigation and risk analysis. To address these challenges, implementation of a Quality Management System (QMS) must emphasize on the importance of temperature mapping and provides guidelines for its proper handling. The QMS should be integrated into the pharmaceutical warehouse management system and should involve all pharmaceutical workers, including medicine distributors and consumers. The concept of temperature mapping process is a critical that should be well-understood and implemented by pharmaceutical workers in pharmaceutical industry, through following proper guidelines and integrating QMS, and the challenges associated with temperature mapping can be minimized, and the quality of pharmaceutical products can be ensured.

Published: March 2023

Dermatofibrosarcoma protuberans (DFSP) is a low-to-intermediate grade sarcoma of dermal origin that rarely presents in the vulva, typically occurring on the trunk of young to middle-aged adults. Even though it has a low potential for distant metastases, it often recurs locally. Therefore, surgical excision is the treatment of choice. We report a case of DFSP with fibrosarcoma transformation involving the vulva treated by large excision with tumor free margins followed by plastic reconstruction. Our object is to highlight this rare disease and through literature evaluate the safety and efficacy of surgical treatment. Early recognition of this rare entity whose localization and the aggressive nature of the fibrosarcomatous component will be an issue in the surgical management.

Published: March 2023

Predicting the behavior of a certain process in time is an important task that arises in many applied areas, and information about the system that generated this process can either be completely absent or be partially limited. The only available knowledge is the accumulated data on past states and process parameters. Such a task can be successfully solved using machine learning methods, but when it comes to modeling physical experiments or areas where the ability of a model to generalize and interpretability of predictions are important, then the most machine learning methods do not fully satisfy these requirements. The forecasting problem is solved by building a dynamic polynomial regression model, and a method for finding its coefficients is proposed, based on the connection with dynamic systems. Thus, the constructed model corresponds to a deterministic process, potentially described by differential equations, and the relationship between its parameters can be expressed in an analytical form. As an illustration of the applicability of the proposed approach to solving forecasting problems, we consider a synthetic data set generated as a numerical solution of a system of differential equations that describes the Van der Pol oscillator.

Published: March 2023

This article examines the impact of a stock exchange’s migration on its trading activity and the performance of competing markets. It examines the importance of the location of trading floors for all market participants; analyzes the relationship between the location of a trading floor and the speed of transactions in the stock market, as well as the impact of accelerating transactions on trading activity. The migration of the Euronext exchange from Paris to Basildon on September 25, 2010, was chosen as the event under study. The method of matched pairs demonstrates the possibility of rationalizing of experimental and control sample for further analysis and modeling of the impact of the relocation of the considered stock market on its and competing exchange’s performance. It is illustrated multidirectional changes in the shares of the value volume of trading and the number of transactions on the Euronext exchange itself and four competing markets. In order to model the impact of the migration of the exchange the method of “difference-in-differences” is suggested, that bases on the use of experimental and control samples and on the construction of regression equations of a special kind. Theoretical bases, advantages and disadvantages of the application of the method of “difference of differences” in the analysis of the impact of certain events on economic results were analyzed. Empirical estimates showed a different expected increase in the value of trading volume after the event on the Euronext and Chi-X Europe exchanges. It is noted that as a result of the migration, the Euronext exchange became closer to the alternative trading floors located in London. This accelerated the execution of transactions between them, and stimulated the alternative markets to become more competitive, faster and more fully reflect the changes taking place on the main Euronext Paris market.

Published: March 2023

In many cases the perfect capital mobility hypothesis is used by default. Therefore, if we follow this idea there should not be any connection between internal savings and investments in a country or at least this connection must be not significant. But some of empirical research demonstrate opposite results. In economic literature this concept is well-known as the “Feldstein — Horioka Puzzle”. Considering the relative lack of studies concerning this theme on the regional level, it seems quite perspective to research the hypothesis from the mesoeconomical point of view. So, the central aim of this article is the verification of regional capital mobility in the Russian Federation, following the logics of the Feldstein — Horioka Puzzle. The main peculiarity of the paper is based on the application a spatial econometric approach. The authors use SLX (spatial lag of X model) and SDM (spatial Durbin model) models to achieve the aim. As the result it was found out that there is almost perfect capital mobility situation on the regional level in the Russian Federation. Hereby the Feldstein — Horioka Puzzle was rejected. Along with it several significant direct and indirect effects were established (for instance, reinforced interaction between geographical neighbors-region, absent of capital flow from some regions and other). The results can be used for the consideration of relatively more efficient regional government policy.

Published: March 2023

The aim of the paper was to study fluctuations of organized activity of ventricular fibrillation of the canine heart. To solve the aim we performed frequency-amplitude analysis of the ventricular electrogram during fibrillation using the Fast Fourier Transform at 30 frequencies in the range of 0.5–15 Hz: 0.5, 1, 1.5, …, 15 Hz. Ventricular fibrillation was characterized by fluctuations of organized activity as evidenced by fluctuations of frequency and amplitude of dominating oscillations when analysing 1-second intervals of fibrillation. Fluctuations of organized activity was maintained in stationary mode as evidenced by disappearance of fluctuations of frequency and amplitude when averaging 1-second values of frequency and amplitude of oscillations in the 3-minute intervals of fibrillation. Stationary fluctuations maintain stability of organized structure of fibrillation during the 30-minute perfusion of the heart.

The article analyses the current legislation and law enforcement practice on patient’s right to choose a medical organization and to choose a doctor under contracts for the provision of paid medical services in the sphere of voluntary health insurance. The efficiency of the realization of patient’s right to health protection and medical care largely depends on the opportunity to properly use the right to choose a doctor and medical organization. The norms of the federal law regulate the procedure for choosing a doctor and a medical organization only when providing medical care to a patient under the program of state guarantees of free provision of medical care to patients. Therefore, when exercising the right to choose a medical organization and a doctor under contracts for the provision of paid medical services within the framework of compulsory medical insurance and within the framework of voluntary medical insurance, patients may encounter practical problems. When providing paid medical services under voluntary health insurance programs, the patient according to the rules has the right to choose a doctor, taking into account his consent. The service of choosing a doctor under contracts for the provision of paid medical services is considered as an additional service.

This study developed a new approach to analyzing mortality and its associated risk factors in the Russian population. We have provided a way to use secondary data from an existing robust research dataset. To do this, we calculated the risk factors for death and assessed the influence of individual risk factors. Previously the datasets have been used earlier for socio-economic research. This paper presents opportunities for studying mortality and associated factors using secondary data to assess disease death outcomes based on the existing cohort — the open license R software to perform data engineering and Relative Risk calculations. There were no instrumental measurements in this study, and all indicators are based on the self-responses to two questionnaires. The data was derived from the Russia Longitudinal Monitoring Survey by the Higher School of Economics. It is a longitudinal, representative survey data from individuals and households from 1990 to 2021. We extracted data on 4063 deaths cases (2214 males and 1699 females) among respondents for further analysis. The lethal fatal outcomes data from the household questionnaires and the records have the proxy respondent’s verbal autopsy status. Thirty-two thousand twenty-three households (around 150,335 individuals) participated in the survey from 1994 to 2019 for 24 years of observations. The most common causes of death were as follows: 974 fatal cases from cerebrovascular disease (stroke), 934 from cardiac disease, and 756 fatal cases due to neoplasms, 1372 cases were registered in females, and 1978 cases were in males.
Creation of collective immune as the main preventive measure for the spread of the new coronavirus infection (COVID-19)
Authors:   I. I. Menshikov North-Western State Medical University, Tovanova Anna
Published: March 2023

Achieving the required level of herd immunity against a new coronavirus infection (COVID-19) in order to protect the population is an urgent issue in preventive and practical medicine around the world. Herd immunity is an indirect indicator of protection against COVID-19 disease and is made up of the immunity of individuals in a particular group. Epidemiological monitoring of the structure, formation, and dynamics of herd immunity will make it possible to correctly and timely adjust approaches to anti-epidemic measures, both in individual risk groups, in particular among medical workers, and in society as a whole. The required level of herd immunity against a new coronavirus infection can be achieved naturally, after a disease, or artificially, through mass immunization of the population. To date, vaccination is the safest, most effective, and most cost-effective method. Serological research methods (detection of IgG) indicate the effectiveness of vaccination — the formation of post-vaccination immunity or a past disease. Determining the period of time at which a stable antibody titer is determined, as well as their level, is essential for predicting morbidity.

Os Parques Científicos e Tecnológicos são instituições promotoras de desenvolvimento tecnológico, científico e socioeconômico regional através da interação entre empresas e instituições de ensino e pesquisa. No sentido de ampliar suas fronteiras, o Estado de Mato Grosso do Sul conta com o primeiro Parque Tecnológico Internacional (PTin), que está em fase de implantação na cidade de Ponta Porã-MS. O objetivo desse estudo foi identificar as principais dificuldades na implantação deste empreendimento, bem como as boas práticas aplicadas no PTin, visando propor sugestões de ações para a consolidação do parque. A metodologia utilizada foi qualitativa, caracterizando-se como documental e descritiva. Para identificar os procedimentos adotados foram realizadas entrevistas, aplicação questionário estruturado, além da participação observante em reuniões com instituições parceiras e diretoria do PTin. Os resultados apontam que uma das principais dificuldades enfrentadas foi uma manifestação política muito forte, o que resultou no delongamento da instalação de sua infraestrutura básica. Ainda, pode-se destacar a carência da participação da sociedade no seu processo prospectivo e a falta de incentivo ao investimento privado. Dessa forma, sugere-se o desenvolvimento de políticas públicas e diretrizes estratégicas para definições e implantação de Boas Práticas do PTin, realização de mecanismos de incentivo ao investimento privado, estruturação de uma equipe de trabalho engajada e comprometida, além de desenvolver programas e ações que atendam suas metas. Diante disso, espera-se que esta pesquisa contribua para o processo de implantação e consolidação do primeiro Parque Tecnológico Internacional na região de fronteira de Mato Grosso do Sul.

Corpus de análise: Uma cidade sem passado (1990) de nacionalidade alemã e Legalidade (2019) filme nacional, e nas séries de tv estadunidenses: Brookyln nine-nine (2013) e Lemony Snicket: Desventuras em séries (2017) como a arquivologia e os arquivistas vem sendo retratados no cinema e na televisão. A escolha por obras que não fossem somente de origem estadunidense deve-se ao fato do cinema hollywoodiano tender a estereotipar suas personagens. A partir das análises podemos perceber que o arquivista, quando aparece, está sob a forma de guardião, e o arquivo parece ser tratado muitas vezes como uma biblioteca que guarda documentos, nos levando a pensar que o fazer arquivístico é associado pela sociedade, como o mesmo realizada em uma biblioteca.

A Arquivística é uma área cativante e motivadora de conhecimento. Isso se justifica por diversos motivos: a missão bibliotecária visa envolver a competência em informação para públicos em vulnerabilidade social, a busca por uma formação continuada, as maneiras de democratizar o acesso à informação que frisam que a pessoa bibliotecária se insere na cultura do privilégio. Merece destaque o fato de que o fazer profissional da arquivística perpassa todas as demais áreas do conhecimento, colaborando na organização e disseminação das informações produzidas em quaisquer campos científicos, o que viabiliza, naturalmente, a aquisição de conhecimentos variados por parte do recém-formado arquivista. A partir dessa afirmação, este artigo relata a participação do recém-formado arquivista no curso de ‘Direitos Humanos para Transformação Social’. Discorre que profissionais da área de ciências sociais aplicadas encontram boas oportunidades ao se especializar nesse campo. Ao final, se atestam as contribuições da experiência, mencionando os benefícios alcançados na construção de uma linguagem mais humanizada – o homem transmite essa linguagem, cria sentido, comunica, prospectando a construção da paz e a defesa da vida nas comunidades.

A pesquisa tem por objetivo identificar se os critérios de avaliação da informação que os adolescentes e jovens (AJ) utilizam ao consumir conteúdo que circula nas mídias sociais encontram correlação com a literatura científica da Ciência da Informação (CI). O estudo compreende a avaliação da informação como uma competência infocomunicacional e as mídias sociais como uma das fontes de informação mais utilizadas por AJ. A abordagem metodológica é de cunho quantitativo e como delineamento do estudo trata-se uma pesquisa de campo. Foram identificados 18 critérios de avaliação da informação na literatura científica da CI e 12 deles foram apontados pelos 196 AJ ouvidos como critérios utilizados. Foi possível identificar que todos os 18 critérios da literatura são utilizados pelos AJ, mesmo que em menor grau. A partir dos resultados, a pesquisa conclui pela necessidade de educação para a informação e ressalta a importância do pensamento crítico.

A informação sempre foi essencial ao ser humano ao longo das décadas, mas ganha grande destaque na contemporaneidade, principalmente com o fenômeno da globalização. Nesse sentido, emerge a vitalidade da Ciência da Informação como domínio que lida com as questões de acessibilidade, divulgação e usabilidade da informação. Nesse contexto, a gestão pública brasileira tem abarcado diversos mecanismos para auxiliar no desenvolvimento de serviços prestados à sociedade, bem como atender aos direitos e princípios constitucionais, como o direito à informação. Assim, em consonância com a necessidade de elucidar os cidadãos acerca das informações, bem como os documentos públicos privados, foi aprovada a Lei 12.527, denominada de Lei de Acesso à Informação, com o fito de transformar as relações documentais do estado em relações de transparência. Visto isso, devido às exigências legais, os municípios brasileiros foram obrigados a criarem portais de transparência para darem publicidade às informações referentes às atividades desenvolvidas pelos entes públicos. A partir dessas definições, esta pesquisa visa realizar o elo entre o acesso à informação pública e às legislações pertinentes à publicidade, transparência da informação e direito à informação, buscando reflexões sobre a atual visão. No que concerne aos aspectos metodológicos, esta pesquisa trata-se de uma revisão bibliográfica de natureza básica e de cunho qualitativo. Por fim, é imperioso destacar que o referencial teórico contido neste trabalho é um recorte de uma pesquisa de dissertação em andamento do mestrado do programa de pós-graduação em Ciência da Informação da Universidade Federal de Alagoas.

A experiência vivenciada por bibliotecários atuantes da Grande Vitória - Espírito Santo com o programa Biblivre - o software livre para catalogação, administração e divulgação de acervos de bibliotecas, é o enfoque dessa pesquisa. O estudo tem natureza qualitativa, utiliza a análise de discurso e também foi realizada uma entrevista com 10 bibliotecários escolares atuantes na região da Grande Vitória – ES, usuários do software, para verificar as percepções dos bibliotecários escolares que atuam em bibliotecas escolares da Região metropolitana da Grande Vitória. Analisa-se a literatura científica sobre o Biblivre com base em uma revisão bibliográfica integrativa da literatura indexada em bases de dados da ciência da informação. Constata-se que a literatura acerca do software ainda é muito incipiente, ainda assim, observa-se em relatos que o sistema de biblioteca livre é vastamente disseminado no território nacional. Concluiu-se nas experiências e relatos dos bibliotecários escolares que o software Biblivre, pode ser descrito como uma plataforma online e gratuita, e uma ótima opção para automatização e organização do acervo de bibliotecas e unidades de informação, em ambiências de escassez de verbas e de políticas públicas. O Biblivre enfoca ferramentas para catalogação e divulgação do catálogo e situam as dinâmicas e as fragilidades da tecnologia que deveria incluir a todos. Assim, a temática Biblivre abarca uma diversidade de aplicações e práticas, tendo a ampla função de promover o acesso à informação, facilitando a viabilização de uma rede de aprendizagens e colaboração – o software é assim um despretensioso tesouro e em uma interdisciplinar esfera envolve a gestão de acervos e direitos.

Diastolic Dysfunction Criteria and Heart failure Readmission in Patients with Heart Failure and Reduced Ejection Fraction
Authors: Lavine Steven J. , Kelvas Danielle
Published: March 2023

Background:

Advanced diastolic dysfunction (DDys) correlates with elevated LV filling pressures and predicts heart failure readmission (HF-R). As grade 2-3 DDys has predictive value for HF-R, and requires 2 of 3 criteria (left atrial volume index >34 ml/m2, E/e’>14, or tricuspid regurgitation velocity >2.8 m/s), we hypothesized that all 3 criteria would predict greater HF risk than any 2 criteria.

Methods:

In this single-center retrospective study that included 380 patients in sinus rhythm with HF and reduced ejection, we recorded patient characteristics, Doppler-echo, and HF-R with follow-up to 2167 days (median=1423 days; interquartile range=992-1821 days).

Results:

For grade 1 DDys (223 patients), any single criteria resulted in greater HF-R as compared to 0 criteria (HR=2.52, (1.56-3.88) p<0.0001) with an AUC (area under curve)=0.637, p<0.001. For grade 2 DDys (94 patients), there was greater HF-R for all 3 (vs. 0 criteria: HR=4.0 (2.90-8.36), p<0.0001). There was greater HF-R for 3 vs any 2 criteria (HR=1.81, (1.10-3.39), p=0.0222). For all 3 criteria, there was moderate predictability for HF-R (AUC=0.706, p<0.0001) which was more predictive than any 2 criteria (AUC difference 0.057, (0.011-0.10), p=0.009). For grade 3 DDys (63 patients), E/A>2+2-3 criteria identified a subgroup with the greatest risk of HF-R (HR=5.03 (4.62-22.72), p<0.0001) compared with 0 DDys criteria with moderate predictability for 2-3 criteria (AUC=0.726, p<0.0001) exceeding E/A>2+0-1 criteria (AUC difference=0.120, (0.061-0.182), p<0.001).

Conclusion:

Increasing the number of abnormal criteria increased the risk and predictive value of HF-R for grade 1-3 DDys in patients with HF with reduced ejection fraction.
