Authors: Szewczyk Jakub , Szypuła Jan , Szczęsny Grzegorz , Tomaszewski Wiesław
Published: August 2024

According to the National Institute of Public Health – National Institute of Hygiene, cardiovascular diseases account for 34.8% of deaths in Poland. In 2020 and 2021, contrary to the previous downward trend, cardiovascular disease mortality increased by 8.7% and 12.6%, respectively [1]. In addition to pharmacological intervention, physical activity, adherence to dietary recommendations, weight reduction, mental health care, and psychosocial and smoking interventions play a key role in preventing the development of cardiovascular disease [2]. In recent years, there has been a growing interest in the impact of lifestyle and environmental factors on the development of cardiovascular risk. The purpose of this study was to evaluate the effects of thermotherapy on cardiovascular fitness indices and to analyze the efficacy and safety of this form of treatment in people with cardiovascular disease. For this purpose, the literature from 2013-2023 available in the Pubmed database was searched. The results of the papers suggest beneficial effects of various forms of thermotherapy on cardiovascular function.

Published: August 2024

One of the oldest specialties in medicine is balneotherapy, which examines how to treat patients with mud and groundwater. Many nations use water therapy as a kind of treatment. The Blue Lagoon in Iceland, the Dead Sea in Israel, the Kangal hot springs in Turkey, several thermal pools in France, as well as Poland, are examples of natural balneotherapy locations. For the patient, this therapy is painless, and there are almost no adverse effects. Its positive effects have also been demonstrated in the management of lupus, psoriasis, atopic dermatitis, rosacea and other inflammatory skin conditions. The primary components of the mechanism are the deep water and peat baths' chemical, mechanical, thermal, and immunomodulatory impacts. It is desirable to use balneotherapies both alone and as a supplement to systemic therapy. Based on the most recent studies and clinical data, this article seeks to assess the present scientific understanding of the role of balneotherapy in dermatological care.

Published: August 2024

Full-thickness skin injuries cause extended inflammation, compromised angiogenesis, and protracted wound healing, presenting considerable health risks. Herein, we introduce an innovative technique utilizing methacrylic anhydride (MA)-enhanced, one-step in-situ extrusion 3D bioprinting of collagen hydrogels, specifically engineered for the effective repair of full-thickness skin injuries. This method capitalizes on the inherent bioactivity of collagen, surmounting its mechanical constraints via a streamlined, one-step extrusion process enabled by MA. The resultant biomaterial ink, an optimized mix of collagen, MA, and photoinitiator, demonstrates superior printability, mechanical robustness, and stability, making it an ideal candidate for direct application onto wound sites. The bioprinted collagen scaffolds exhibit improved mechanical strength, reduced swelling, and enhanced resistance to enzymatic degradation, providing a durable matrix for cell proliferation and tissue in-growth. In vitro assessments reveal that the scaffolds support human foreskin fibroblast adhesion, proliferation, and migration, creating a conducive environment for skin regeneration. In vivo evaluations, conducted using a rat full-thickness skin injury model, further validate the scaffold's efficacy in promoting rapid and orderly tissue repair, characterized by accelerated re-epithelialization and organized collagen deposition. This MA-enhanced, in-situ extrusion 3D bioprinting technique generates collagen hydrogel scaffolds that significantly accelerate wound healing, offering promising advancements in tissue engineering and regenerative medicine.

Time Cost Trade-Off Problem Using Intuitionistic Fuzzy with Real Time Application in the Field of Construction
Authors: S Priyadharshini , G Deepa
Published: August 2024

In order to assist in locating the critical path in an acyclic network, the Critical Path Method (CPM) employs intuitionistic triangular fuzzy number. Project crashing is a technique used to cut the project timeline fast by minimizing the duration of one or more critical task below their typical duration. The goal of crashing, often referred to as the time-cost trade-off, is to shorten the project’s duration while lowering its cost. The intuitionistic fuzzy critical path technique and the time-cost trade-off issue were developed as a result of the uncertainty or ambiguity around the length of activities. The present investigation proposes an optimal method for handling the time-cost trade-off problem (TCTP). When the duration aspect is taken into account, the project’s overall cost is effectively reduced. It is simpler to compute the time and monetary expenses of being on the critical path while using this approach. An existing application from the literature is selected and implemented to demonstrate the operation of this technology. Additionally, we suggested a ranking method for defuzzification called “Magnitude measure”. Both the traditional approach and the path length ranking methodology are used for verification. MATLAB is used to give simulation results.

Purpose of the study. Studying the features of microcirculation, functional state and anatomy of the heart using the “Holiday Heart” syndrome model in rats we developed.

Materials and methods. Experiments were carried out on white outbred male rats. The “Holiday Heart” syndrome was modeled as follows: animals received a 10 % aqueous ethanol solution as the only source of fluid for the first 10 days, then tap water for 10 days, and again a 10 % aqueous ethanol solution for the next 10 days. One day after the end of the repeated intake of alcohol, the animals were taken into the experiment. Animals that received free access to tap water served as control. Some rats in the experimental group (n = 10) had an echocardiogram recorded before the start of the experiment, and on the 31st day of the experiment, after which the level of microcirculation of blood and lymph in the brain and heart was measured using laser Doppler flowmetry. In the remaining animals (n = 10), microcirculation of blood and lymph in the brain and heart was assessed on the 3rd day of alcohol deprivation.

Results. Analysis of the obtained data showed that in the conditions of the “Holiday Heart” syndrome model, significant changes occur in the anatomy, functional activity and geometry of the heart: there is a significant thinning of the anterior wall of the left ventricle heart (LV), an increase in systolic and diastolic volumes and sizes of the LV and a significant (p = 0.0018) decrease in its inotropic function. These changes occur against the background of a significant (p = 0.0081) decrease in the level of blood microcirculation in the myocardium, however, on the 3rd day of deprivation, blood flow in the microvessels of the heart increases statistically significantly (p = 0.0285).

Conclusion. In model experiments reproducing the “Holiday Heart” syndrome, it was shown for the first time that ethanol causes significant changes in the microcirculation, anatomy, functional activity and geometry of the left ventricle of the heart, which, apparently, can play a key role in the formation of myocardial electrical instability pathognomonic for this syndrome.

Authors: Akin-Otiko Bridget Omowumi , Hassan Joy Olajumoke
Published: August 2024

Family planning (FP) allows individuals and couples to anticipate and attain their desired number of children and the spacing and timing of their births. It is achieved through use of contraceptive methods and the treatment of involuntary infertility. A woman’s ability to space and limit her pregnancies has a direct impact on her health and well-being as well as on the outcome of each pregnancy; thereby, promoting the health and welfare of family groups and effectively contributing to the social development of a country. The study was conducted to determine the pattern of utilization of family planning services among women of reproductive age attending the Comprehensive Health Centre, Oba-Ile, Akure, Nigeria. A sequential mixed method explanatory research approach was adopted for the study, with an initial retrospective quantitative data collection from clients’ records for the 5-year period (2016-2020); followed by a qualitative data collection using in-depth interview of key informants to provide further explanation on the key findings from the quantitative phase. The findings revealed that of the randomly selected 317 records, majority 147(46.4%) of the women were aged 21-30 years and the mean age was 30.48years; 302 (95%) of them were married; and they all had formal education; although, only 43(13.56%) had tertiary education. Over two-thirds of them 253 (79.8%) were employed; while, 30(9.46%) were students and 34(10.72%) were either unemployed or full housewife. Those with Parity 1-3 were 212(66.9%), and only 4 (1.3%) had 7-10 children; while, the mean parity was 3. The total number of women utilizing family planning services in the facility annually, increased from 132 in 2016 to 713 in 2020. The sample did not reveal any quarterly pattern of utilization of the services by the women. The study also showed that majority (37.9%) of the women used the Jadelle method of family planning, followed by Implanon (30.9%); and majority of the clients did not change their choices (57.1%). The qualitative data revealed the need for sustained presence of family planning providers and continued support from development partners; as the drop in 2017 was reportedly due to lack of a provider, while the consistently improved attendance thereafter was attributed to the collaboration with development partners.

Geological mapping carried out in Gombe area revealed the presence of Yolde, Pindiga and Gombe Sandstone Formations. But in the case of this study, only the silicalstics of Yolde Formation are used for the Petrographic investigation. Petrographic analysis results indicate that Quartz is the dominant mineral in all the studied slides followed by potassium feldsper (Orthoclase), Iron oxide, altered feldspers, whereas Limonite and Zircon appear thrice each. Quartz framework grain is abundant due its greatest resistant to chemical decomposition and mechanical abrasion, Orthoclase is the only feldspers mineral present due to resistant than most of them. Altered feldspers is an opaque mineral visible only under cross-polar, it is believed to have been formed due to alteration of ferro- magnesian minerals. Zircon is the only non-stable opaque mineral present due to ability to withstand abrasion weathering, it is found in recycled sedimentary facies. Stable opaque present are Iron oxide and Limonite. Limonite results from dissolution of hematite and sometimes it is referred to as goethite or Iron ore. Iron oxide in this study is undifferentiated, because in theory, it represents both hematite and magnetite, then to a lesser extent, the rarer oxide mineral maghemite. It was observed in all the slides and this suggests that the Yolde Formation of the study area have been intensely weathered and most have travel some distance from source rock. Its provenance can be said to be from

Published: August 2024

The rising abundance of vibrant networks, like Mobile Ad-hoc Networks (MANETs), Wireless Sensor Networks (WSNs), and Flying Ad-hoc Networks (FANETs) requires sophisticated cryptographic solutions to protect multimedia information delivery. This paper offers a thorough review of computationally competent and random key-based image cryptography adapted for vibrant network circumstances. We search the background of image cryptography alongside an emphasis on algorithms and strategies that highlight computational competence and the utilization of random keys for improved protection. Key ranges enclosed comprise conventional symmetric and asymmetric encryption schemes, trivial cryptography, and logistic system related key production schemes. The paper explores the capabilities and restraints of these schemes based on encryption time, key administration and protection strength. An exhaustive examination of several random key production schemes is offered, exhibiting how these schemes cause to enhance randomness and vigour in cryptography. We deliberate the incorporation of these schemes in vibrant networks where systems frequently tackle restrictions such as rare processing energy, storage and power. The paper also discusses the issues impersonated through such circumstances, containing the requirement for real-time information processing, flexibility and compliance to modify network situations. The paper calculates the strength of latest techniques utilizing performance vectors like encryption speed, key sensibility and resilience to cryptanalysis attacks.

Challenges of multipurpose cooperatives in the marketing of agricultural products in the southwest part of Ethiopia
Authors: Wakweya Rusha Begna
Published: August 2024

Agricultural cooperatives, particularly multipurpose cooperatives, are considered a valuable means of improving the livelihoods of small-scale farmers in developing countries. By collaborating with farmers, they can increase their collective bargaining power, negotiate better prices for their crops, and boost their incomes. However, despite their significant contributions, multipurpose cooperatives face challenges that can hinder their ability to play a significant role in agricultural product marketing. This study aimed to analyse the challenges of multipurpose cooperatives in the marketing of agricultural products in the southwest part of Ethiopia. A two-stage sampling technique was used to select a sample size of 196 members from four multipurpose cooperatives. A mixed research design, which combines both qualitative and quantitative data collection methods, was used. Quantitative data was collected through a structured questionnaire from primary sources, while qualitative data was collected through focus groups and key informant interviews. Descriptive statistics such as mean, chi-square, standard deviation, frequency, and percentage were used to analyse the data. The study revealed that the multipurpose cooperatives in the study area faced several internal and external constraints. The key internal challenges were a lack of capital, an unskilled workforce, and low commitment from committee members. On the other hand, the major external bottlenecks included inadequate and inconsistent technical assistance, deficiency in knowledge and skills, and inadequate documentation and information in the marketing of the multipurpose cooperatives. The study suggests that the government and other non-governmental organisations should provide financial and technical support to encourage cooperatives.
Palaeolithic innovations in response to faunal fluctuations
Authors: Litov Vlad , Barkai Ran
Published: August 2024

Animal acquisition, butchering and processing was a crucial activity continuum in the subsistence of Lower Palaeolithic hunter-gatherers bolstered by a persistent Acheulian stone toolkit. Scrapers, bifaces, flakes and other Acheulian implements were successfully used during carcass manipulation, entailing functional compatibility with the prey taxa to be processed. Major changes to the Acheulian butchery toolkit occurred in the late Lower Palaeolithic Levant, with the introduction of novel lithic trajectories stemming from anchored Acheulian traditions. This paper presents two late Acheulian innovations: Quina-like scrapers and flat bifacial knives. Both tool types emerge at a different pace and are rarely recognised in Acheulian contexts. However, numerous fully-fledged Quina scrapers used for butchery and hide working are characteristic of the proceeding Acheulo-Yabrudian Cultural Complex in the Levant, where they are supplemented by a limited number of flat bifaces. Changes to local faunal communities, marked by a decline in megaherbivore availability, may have accelerated the introduction of a new set of butchery implements oriented towards effective processing of smaller-sized ungulates, a habitual Acheulo-Yabrudian subsistence pattern. Dependency on animal-induced calories and underlaying human–animal relationships may have facilitated the development of new butchery implements acting as ‘mediators’ between humans and their preferred prey. The gradual emergence of new butchery tools may signal the practical and ontological adaptability of late Lower Palaeolithic hunter-gatherers to new ecological conditions and trophic interactions in a time of shifting faunal communities and highlight the paramount role of human–animal relationships in Lower Palaeolithic cultural evolution.

Authors: Tharmabalan Rachel Thomas
Published: August 2024

The Orang Asli is a term commonly used to describe one of the indigenous people in Peninsular Malaysia. The Semai, a subgroup of the Orang Asli, remain reliant on the rainforests for wild edible plants and wild game for their nourishment. As such, this research was conducted to identify the food consumption patterns and gender role allocation regarding hunting and gathering practices among the Semai. A total of 24 informants from three villages were interviewed for this research using both semi-structured interviews and participant observation methods. The findings show that the Semai consume rice, cassava, wild edible plants and wild animals based on their geographical location. Gender allocations can be observed in all three villages where the men hunt wild animals and the women gather wild edibles. The findings of this study may provide insights into Semai food culture and contribute to the development of culturally appropriate nutrition programmes and interventions for this community.

M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the GWAC, with flare energies ranging from 1032.2 to 1036.4 erg. The flare amplitudes range from △G = 0.84 to ∼10 mag. Flare energy increases with stellar surface temperature (T
eff) but both △G and equivalent duration

seem to be independent of T
eff. Combining periods detected from light curves of TESS and K2, spectra from LAMOST, the Sloan Digital Sky Survey, the 2.16 m telescope, and the Gaia DR3 data, we found that these GWAC flare stars are young. For the stars that have spectra, we found that these stars are in or very near the saturation region, and

Energy dissipation in collisionless plasmas is one of the most outstanding open questions in plasma physics. Magnetic reconnection and turbulence are two phenomena that can produce the conditions for energy dissipation. These two phenomena are closely related to each other in a wide range of plasmas. Turbulent fluctuations can emerge in critical regions of reconnection events, and magnetic reconnection can occur as a product of the turbulent cascade. In this study, we perform 2D particle-in-cell simulations of a reconnecting Harris current sheet in the presence of turbulent fluctuations to explore the effect of turbulence on the reconnection process in collisionless nonrelativistic pair plasmas. We find that the presence of a turbulent field can affect the onset and evolution of magnetic reconnection. Moreover, we observe the existence of a scale-dependent amplitude of magnetic field fluctuations above which these fluctuations are able to disrupt the growing of magnetic islands. These fluctuations provide thermal energy to the particles within the current sheet and preferential perpendicular thermal energy to the background population.

Pulse profile modeling of X-ray data from the Neutron Star Interior Composition Explorer is now enabling precision inference of neutron star mass and radius. Combined with nuclear physics constraints from chiral effective field theory (χEFT), and masses and tidal deformabilities inferred from gravitational-wave detections of binary neutron star mergers, this has led to a steady improvement in our understanding of the dense matter equation of state (EOS). Here, we consider the impact of several new results: the radius measurement for the 1.42 M
⊙ pulsar PSR J0437−4715 presented by Choudhury et al., updates to the masses and radii of PSR J0740+6620 and PSR J0030+0451, and new χEFT results for neutron star matter up to 1.5 times nuclear saturation density. Using two different high-density EOS extensions—a piecewise-polytropic (PP) model and a model based on the speed of sound in a neutron star (CS)—we find the radius of a 1.4 M

Phylogenetic classification of arbuscular mycorrhizal fungi: new species and higher-ranking taxa in Glomeromycota and Mucoromycota (class Endogonomycetes)

Published: August 2024

Arbuscular mycorrhizal (AM) fungi - Glomeromycota and Endogonomycetes - comprise multiple species and higher-level taxa that have remained undescribed. We propose a mixed morphology- and DNA-based classification framework to promote taxonomic communication and shed light into the phylogenetic structure of these ecologically essential fungi. Based on eDNA samples and long reads as type materials, we describe 15 new species and corresponding genera (Pseudoentrophospora kesseensis, Hoforsa rebekkae, Kahvena rebeccae, Kelottijaervia shannonae, Kungsaengena shadiae, Langduoa dianae, Lehetua indrekii, Lokruma stenii, Moostea stephanieae, Nikkaluokta mahdiehiae, Parnigua craigii, Riederberga sylviae, Ruua coralieae, Tammsaarea vivikae and Unemaeea nathalieae), the genus Parvocarpum as well as 19 families (Pseudoentrophosporaceae, Hoforsaceae, Kahvenaceae, Kelottijaerviaceae, Kungsaengenaceae, Langduoaceae, Lehetuaceae, Lokrumaceae, Moosteaceae, Nikkaluoktaceae, Parniguaceae, Riederbergaceae, Ruuaceae, Tammsaareaceae, Unemaeeaceae, Bifigurataceae, Planticonsortiaceae, Jimgerdemanniaceae and Vinositunicaceae) and 17 orders (Hoforsales, Kahvenales, Kelottijaerviales, Kungsaengenales, Langduoales, Lehetuales, Lokrumales, Moosteales, Nikkaluoktales, Parniguales, Riederbergales, Ruuales, Tammsaareales, Unemaeeales, Bifiguratales and Densosporales), and propose six combinations (Diversispora bareae, Diversispora nevadensis, Fuscutata cerradensis, Fuscutata reticulata, Viscospora deserticola and Parvocarpum badium) based on phylogenetic evidence. We highlight further knowledge gaps in the phylogenetic structure of AM fungi and propose an alphanumeric coding system for preliminary communication and reference-based eDNA quality-filtering of the remaining undescribed genus- and family-level groups. Using AM fungi as examples, we hope to offer a sound, mixed framework for classification to boost research in the alpha taxonomy of fungi, especially the “dark matter fungi”.
De la formation-action à l’intervention collective en travail social
Authors: Laurence Pierre
Published: August 2024

L’intervention collective, comme le pouvoir d’agir et l’empowerment, est l’une des composantes importantes en travail social. Cette pratique touche l’ensemble de l’organisation de la société et s’inscrit dans une approche globale, intégrée, territorialisée et inclusive. « L’intervention collective vise à apporter une solution collective et solidaire à un problème social ou à un besoin commun » (Lamoureux et al., 1994, p.19). Plus précisément, c’est une méthode d’intervention qui vise à s’attaquer aux problèmes sociaux dans une perspective de gouvernance démocratique et de participation citoyenne. C’est ainsi qu’en 2017 et 2018, une dizaine d’agences regroupant une cinquantaine d’intervenants, du bailleur social Lyon Métropole Habitat (LMH), ont été accompagnées par une formation en intervention collective axée sur les fondements, les pratiques et la méthodologie de l’intervention collective par un chercheur/formateur du Québec. Cet article précise à travers la formation les contenus, les modalités de mise en œuvre, l’impact sur les modes d’intervention et de gestion de LMH, la participation des habitants, les conditions de réussite et/ou les leçons pour assurer une pérennité de la formation , et enfin, les enjeux reliés à la formation et aux pratiques en travail social pour consolider l’intervention collective.
Organiser le travail sans manager : étude des processus de régulation au sein d’une organisation autogérée
Authors: Nivet Brigitte , Postaire Maxence
Published: August 2024

Cet article montre les processus de régulation au sein d’une organisation autogérée. La particularité de l’organisation autogérée est d’être sans manager. Le pouvoir et le travail y sont répartis parmi les membres. Ceci en fait un cas intéressant pour étudier les processus de création de règles. En mobilisant la théorie de la régulation sociale et en nous appuyant sur des observations et la conduite d’entretiens semi-directifs, nous mettons au jour les processus de régulation à l’œuvre. Nos résultats soulignent la présence de processus de régulation dans une organisation autogérée. L’émergence de la régulation autonome n’est pas, dans ce type d’organisation, qu’une réaction à la régulation de contrôle. Nos résultats mettent en valeur également que la présence de métarègles de contrôle contient une légitimité symbolique qui cadre les processus de régulation et fonde les règles de contrôle.
Quels impacts des événements de vie personnelle du salarié sur ses relations de travail avec l’équipe ?

La littérature en Gestion des Ressources humaines s’intéresse peu aux incidences possibles des événements de vie personnelle sur le comportement au travail des salariés, encore moins à celles sur leurs relations de travail avec leurs équipes. Quels impacts les événements de vie personnelle rencontrés par un salarié peuvent avoir sur ses relations de travail avec l’équipe ? L’article explore cette problématique par le biais du point de vue des managers. Une approche par les transferts interpersonnels a été utilisée comme cadre conceptuel général. Deux théories, affiliées à cette approche, ont été utilisées pour interpréter les données empiriques : la théorie du crossover et la théorie de l’échange social. Nous employons une méthodologie qualitative. Des entretiens semi-directifs ont été menés auprès de 27 managers d’une grande entreprise des Industries électriques et gazières françaises. Ils ont été analysés à partir d’un codage mixte, basé sur des concepts préexistants et émergents. L’article apporte deux contributions à l’étude du lien entre événements de vie et travail : il met en lumière les transferts (« crossovers ») négatifs (ex. : charge de travail, affects négatifs…) ou positifs (ex. : soutien émotionnel, instrumental…) survenant en séquences dynamiques entre les salariés en difficulté et leurs équipes ; il souligne l’influence que peut jouer la norme de réciprocité.
