Authors: Esmaealpour Asrin , Sharma Manoj , Mirghafourvand Mojgan , Pourrazavi Sara , Allahverdipour Hamid
Published: November 2022

Background: Girls need special care regarding menstrual hygiene because of early pubertal development and related problems. The researchers aimed to explore the knowledge about the role of the mother-daughter relationship in menstrual hygiene among young teens. Methods: A cross-sectional study was conducted (February-April 2020) among 190 elderly young teenage girls in middle schools who lived in Bukan, North-West of Iran. Data about demographic characteristics, menstrual information, knowledge of menstrual hygiene management, the practice of menstrual hygiene, the premenstrual symptom screening tool, visual analog scale for pain, and parent-child relationship survey were collected by a questionnaire using a multistage random sampling method. Finally, the obtained data were analyzed using SPSS (version 25) through descriptive and analytical statistics. Results: The most common severe signs and symptoms were anger/irritability (21.6%), fatigue/lack of energy (19.5%), and decreased interest in household activities (17.9%). A sense of shame was reported more among girls who have moderate relationships with their mothers (P=0.011), and a significant relationship was found between mothers’ low literacy and the severity of premenstrual symptoms in their daughters (P=0.036). Conclusion: Mothers play a crucial role in their daughters’ lives, which can buffer stressors and relieve anxiety, especially during the experiencing of menarche and during the menstruation period, indicating familial support to overcome the puberty-related crisis.

Published: November 2022

Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) constitutes a source of great concern to health authorities worldwide. Herbal medicinal products are used as a significant treatment option for highly active antiretroviral therapies, the efficacies of which are negatively impacted by the emergence of multidrug-resistant strains to the recommended treatment guidelines. This review provides an updated synopsis of available documents on herbal medicinal products with anti-HIV activities. Concurrent consumption of herbal products with conventional drugs, which is often necessitated by co-morbidity of HIV with other diseases, can potentially alter the pharmacokinetics of the co-administered orthodox drugs. Phytochemical constituents of the herbal medicinal products with antiretroviral activities were identified, and their potential to mediate pharmacokinetic changes through modulation of drug-metabolizing enzymes and P-glycoprotein was reported. Herb-drug interactions (HDIs) that can result in significant adverse effects were also discussed with documenting the information for the therapeutic utility of these clinically effective antiretroviral herbal medicinal products with potential for development into newer anti-HIV drugs.

Published: November 2022

Introduction: Ficus capensis has been used in traditional medicine to treat anaemia, tuberculosis, convulsion, pains, wounds, respiratory disorders, and other health challenges. This study investigated the effect of F. capensis ethanolic leaf extract in phenylhydrazine (PHZ)-induced anaemia in Wistar rats. Methods: Induction of anaemia was done by intraperitoneal administration of PHZ (40 mg/kg for 48 hours). A normal group and an anaemic group were treated daily with a single dose of 20 mL/kg of distilled water and considered as control and anaemic (non-treated) groups. Then, the remaining groups were treated with 100, 200, and 400 mg/kg of ethanol extract of F. capensis leaves for 21 days, respectively. Blood samples from the rats were run in three batches of baseline, post anaemia induction, and post-treatment. Phytochemical screening and acute toxicity tests of the extract were also carried out following standard procedures. Results: The results showed a consistent significant increase in haematological parameters among various experimental groups. Haemoglobin (Hb), red blood cell (RBC) count, mean corpuscular volume (MCV), packed cell volume (PCV), mean cell haemoglobin (MCH) and Mean cell haemoglobin concentration (MCHC) values of treated rats were significantly increased compared to the anaemic control. The secondary metabolites of leaf extract were alkaloids, saponins, tannins, steroids, flavonoids, phenols, and reducing sugar, while the acute toxicity test was found to be non-toxic at 5000 mg/kg in rats. Conclusion: The ethanol leaf extract of F. capensis might provide an alternative cure for anaemia and boosts blood count.

Introduction: Anemia is a common health condition caused by a decrease in red blood cells. Some medicinal plants are used as a remedy to treat anemia. This study compares the anti-anemic properties of different doses of the aqueous extracts of Ficus capensis (AEFC) and its combination with the aqueous extract of Cnidoscolus aconitifolius (AECA) in phenylhydrazine-induced anemic rats. Methods: Anemia was induced by intraperitoneal injection of 20 mg/kg phenylhydrazine for five consecutive days. Graded doses of the extracts were given by oral gavage once a day continuously for 30 days. At the end of the treatment, blood was collected for hematological analysis. Results: The antianemic effects of AEFC and its combination with AECA were demonstrated by significant increases (P < 0.05) in the hemoglobin (HGB), packed cell volume (PCV) and red blood cell (RBC) count of the extract-treated groups compared to the anemic control group. There was a better increase in the HGB levels of a combination of 400 mg/kg AEFC + AECA (13.97 ± 2.53) compared to 400 mg/kg AEFC (12.06 ± 0.02). The PCV increased more in 400 mg/kg combination of AEFC + AECA (41.94 ± 0.37) compared to 400 mg/kg AEFC (36.31 ± 1.51). A significant (P < 0.05) increase was observed in the RBC count of a combination of 400 mg/kg AEFC + AECA (6.36±0.51) compared to 400 mg/kg AEFC (4.75 ± 0.46). Conclusion: Although AEFC improved the haematological parameters of the animals when administered alone, its combination with AECA yielded a far much better result by totally restoring the haematological parameters of the phenylhydrazine-induced anemic rats to normal.

Published: November 2022

Introduction: Candida albicans is an important opportunistic pathogen that is responsible for most fungal infections in humans. Secondary metabolites are known to be antimicrobial and antifungal agents. This study aimed to investigate the chemical composition of Prangos ferulacea and P. uloptera essential oils and evaluate the sensitivity of four genera of Candida. Methods: After collecting plant samples, their essential oils were extracted by the distillation method, and their components were analyzed using Gas chromatography–mass spectrometry to identify constituents. In total, 48 species of Candida isolated from clinical specimens were examined in this study. The antifungal activities of essential oils of P. ferulacea and P. uloptera were evaluated according to CLSI M27-A3 compared to fluconazole. Results: Out of the two tested plants, P. ferulacea had the lowest minimum inhibitory concentration (MIC) against Candida species. However, MIC of this plant against C. albicans isolates was higher than 0.121 μL/mL non-albicans species. Both plants were able to inhibit non- albicans species with MIC90 values of 0.0097 and 0.039 μL/mL. However, their MIC90 values were less than fluconazole against Candida isolates. Conclusion: The results of this study suggest that P. ferulacea and P. uloptera essential oils might be used as new antifungal agents.

Mapping of protective forest coverage of territories and assessment of its optimality
Authors: Tubalov Alexey
Published: November 2022

Protective forest plantations are an integral part of agroforestry landscapes that serve as an ecological frame and contribute to the expanded reproduction of soil fertility. The problem of assessing the actual protective forest cover of territories is relevant. The solution of this issue allows you to identify the need, sequence and volume of forest reclamation work. The problem of mapping and assessing the protective forest cover of territories is closely related to the tasks of identifying the optimal forest cover of territories and substantiating approaches to the allocation of spatial-territorial complexes. The boundaries of the identified contours directly affect the values of specific indicators, which are the basis for the gradation of the need for forest reclamation work. The conducted studies demonstrate the possibilities of using the QGIS software package for the purpose of assessing the protective forest cover of the territory. The interpretation and creation of a cartographic model of protective forest plantations of the study area was carried out using QuickBird satellite images. The assessment was made on the basis of the calculation of specific indicators within the boundaries of landscapes for the territory of the Ilovlinsky District of the Volgograd region. As a standard for comparing the studied indicators, indicators of the protective forest cover of the “Kachalino” pilot farm were used. The application of the landscape-typological approach to the identification of territorial complexes made it possible to approach the issue of assessing the protective forest cover of territories in a more differentiated way than when using administrative boundaries. As a result of the study, landscape areas were identified, the protective forest cover of which is close to the normative, as well as those areas that need agroforestry measures. Cartographic work carried out in the QGIS software package confirms its effectiveness and allows us to recommend its use in agroforestry research related to the parallel application of various approaches to the allocation of territorial complexes.

Published: November 2022

Due to the increase in the areas of disturbed lands, the relevance of developing methods and methods for obtaining and analyzing spatial data in order to make decisions on rational nature management is increasing every year. Monitoring of natural and anthropogenic systems is largely related to the collection, analysis and visualization of dynamic processes, so the technologies for compiling of dynamic maps are at the peak of relevance. A number of factors necessitate the using of dynamic geoimages. Firstly, these images are an inseparable combination of spatial-temporal links on the certain areas. Secondly, it is the possibility of a full-fledged analysis of spatial changes taking into account time. Thirdly, it is the forecasting of natural and socio-economic factors and phenomena. In addition, dynamic mapping opens up opportunities for multimedia data visualization, which increases the observer’s perception of geoimages by several times with the focus on specific objects. Remote sensing data is one of the main sources for compiling and updating thematic dynamic maps. This article demonstrates the development of the method for creating working layers used in geographic information systems (GIS) for compiling dynamic maps using remote sensing data. The authors note a distinctive feature of the methodology: it is aimed at a wide range of users who do not fully have the skills and abilities to work with remote sensing data. These are managers of any level, whose direct work is not related to the compiling of geo-images, but whose competence is to make managerial decisions. Another advantage of the described methods is its implementation in an open source GIS (QGIS), as well as its application not only for single images, but also for a mosaic image. The article presents a description of the entire path from image processing to the creation of visual images. Disturbed lands of the Zabaykalsky Krai of the Russian Federation were chosen as a special example of working polygons. These territories have a large number of environmental problems, causing an increase in the areas of disturbed lands: open pits, an increase in the number of mining and processing factories, degradation of agricultural and forest lands due to anthropogenic activities and erosion processes, active seismic processes, mudflows and avalanche hazard.
Agroforestry assessment of protective forest stands using remote data and geoinformation technologies
Authors: Koshelev Alexander , Shatrovskaya Maria
Published: November 2022

At present, it is not economically feasible to use ground methods for inventorying forest plantations, since the scale and relevance of this process have increased significantly, which requires promptness in solving problems of recognizing protective forest belts from aero and space images and deciphering them. From this it follows that in order to draw up recommendations on forest reclamation measures aimed at increasing the durability of forest plantations, it is necessary to use the available remote sensing data and modern GIS technologies when examining protective forest plantations. The use of modern technologies will allow for a more qualitative assessment of the state of forest plantations in the Volgograd region. The use of the free desktop geographic information system QGIS in research demonstrates a number of possibilities, in particular, deciphering the current state and conducting digital inventory mapping of protective forest plantations based on GIS technologies and aerospace methods. Subsequently, the obtained data will be applied in the development of methods and principles that are scientifically substantiated and aimed at the rational use of resources and the regulation of anthropogenic impacts on the agroforest landscapes of the region. The study was carried out in the southern part of the Ilovlinsky District of the Volgograd region, located in the subzone of chestnut soils on the Kachalino test site. As a result of the study, the use of QGIS made it possible to decipher protective forest plantations in order to determine their spatial distribution, quantity, species and structural composition. On the laid out sites, the main reference schemes of rock mixing were compiled and key signs of protective forest belts were identified during interpretation. The mapping of the forest fund was carried out on the basis of data obtained in the course of visual and instrumental interpretation. The results obtained will become the basis for the development of a regional agroforestry reclamation geoinformation system necessary for updating existing forest maps, monitoring the state of forest plantations and planning various forest management activities aimed at the effective management of the agroforestry fund of the Volgograd region.

Published: November 2022

The problem of timely and accurate assessment of the erosion hazard of the territory is quite acute for the agro-industrial complex of our country, since erosion processes cause great damage to agriculture. To ensure the work on the rational organization of the territory and competent land management support for these actions, it is necessary to use modern technologies and modern software in the field of geographic information systems. Thanks to geographic information systems, it becomes possible to quickly and efficiently create sufficiently accurate and informative planning and cartographic material necessary for the development and implementation of projects for the anti-erosion organization of the territory. This paper describes the main indicators of the erosion hazard of land, shows the methodology for their calculation using geographic information systems on the example of agricultural producers of the Okhansky District of the Perm region. In the course of the work, cartographic images of the study area, soil features of the study area, reclassification of the raster of soils and parent rocks, relief of the study area, slope slopes and reclassification of the slope raster, exposure of slopes and reclassification of the slope exposure raster, allocation of cultivated lands, image of types of land use and raster reclassification using types, distribution of the LS factor on the territory and reclassification of the LS factor raster, image of the erosion potential of the territory. The use of the developed planning and cartographic material will greatly facilitate the information support of the process of land management and anti-erosion organization of the territory. It is recommended to use data on the erosion hazard potential of lands in the development of municipal program documents in the field of rural development in the Okhansky District. The standards developed for agricultural enterprises can be used in municipal programs for the development of the industry, in the process of planning and organizing agricultural production.
democracia brasileira morreu?
Authors: Oliveira Herberth Heloy Amaral de
Published: November 2022

Há algum tempo que a estabilidade institucional do Brasil está em falta, que os pilares da nossa jovem democracia estão fragilizados e que a política está cada vez mais polarizada. O processo de desestabilização que se iniciou com as jornadas de junho de 2013, tomou força com o impeachment da ex-presidente Dilma Rousseff e que culminou com a eleição de Jair Bolsonaro em 2018 nos mostra que a crise se normalizou no sistema político, social e econômico do país. Com base na análise exposta no livro Como as Democracias Morrem sobre o ressurgimento do autoritarismo em democracias contemporâneas através dos próprios mecanismos desse regime, o presente artigo pretende versar sobre a história recente do Brasil, focando, principalmente, no papel desempenhado por Jair Bolsonaro no processo de erosão democrática que o país enfrenta, como foi possível o aprofundamento dessa crise política e como revertê-la sem apelar para medidas estranhas à Constituição. Será explorada, também, a relação dessa crise com o fenômeno nacional-populista que tem estado presente na cultura política de vários países ocidentais desde o início do século XXI e que representa a mais urgente ameaça aos valores políticos herdados do iluminismo na contemporaneidade, mesmo em países com instituições fortes e estáveis.

The Meat Eater Problem
Authors: Plant Michael
Published: November 2022

Here are two commonly held moral views. First, we must save strangers’ lives, at least if we can do so easily: you would be required to rescue a child drowning in a pond even if it will ruin your expensive suit. Second, it is wrong to eat meat because of the suffering caused to animals in factory farms. Many accept both simultaneously—Peter Singer is the pre-eminent example. I point out that these two beliefs are in a sharp and seemingly unrecognised tension and may even be incompatible. It seems universally accepted that doing or allowing a harm is permissible—and may even be required—when it is the lesser evil. I argue that, if meat eating is wrong on animal suffering grounds then, once we consider how much suffering might occur, it starts to seem plausible that saving strangers would be the greater evil than not rescuing them and is, therefore, not required after all. Given the uncertainties and subjective assessments here, reasonable people could substantially disagree. The surprising result is that a moral principle widely considered to be obviously true—we must rescue others—is not, on further reflection, obviously true and would be defensibly rejected by some. Some potential implications are discussed.
Векторная градиентная теория упругости

Published: November 2022

Рассматриваются градиентные теории упругости Миндлина — Тупина, которые являются основой для
теоретического описания материалов с учётом масштабных эффектов. Впервые предлагается процедура,
позволяющая существенно упростить прикладные градиентные теории упругости, являющиеся основ-
ным инструментом теоретического моделирования наноструктурированных материалов. Показывается,
что тензоры градиентных модулей упругости представляются в виде разложения по тензорному базису
пяти тензоров шестого ранга, три из которых подчиняются особому свойству, благодаря которому соот-
ветствующая квадратичная форма для плотности потенциальной энергии является свёрткой векторов.
Такие модели, называемые «векторными», обеспечивают классический вид статических граничных усло-
вий. Это позволяет избежать характерных для градиентных теорий трудностей, связанных с реализаци-
ей краевых условий на рёбрах поверхности при теоретическом и численном моделировании.
Escuta feminista e a revelação de violências invisíveis
Authors: Barreto Beatriz Jorge
Published: November 2022

Diante do cenário de conflitos e violências observado nos relacionamentos interpessoais em universidades, constata-se que estudantes mulheres são as maiores vítimas dessas agressões. O período 2013 – 2019 foi marcado pelo crescimento no número de acusações e denúncias de violência registradas na Ouvidoria da Unesp e, concomitantemente ao recrudescimento das agressões, ocorre intensa atuação dos movimentos estudantis de resistência a essas práticas na universidade. Este artigo objetiva analisar as experiências do Núcleo MAJU (2018) e do Movimento “Meu professor abusador” (2019), ambos compreendidos como táticas institucionais de escuta feminista que, segundo Sara Ahmed (2021), são capazes de ouvir queixas, quebrar barreiras e impedir que as violências se perpetuem de forma invisível e inaudível nas universidades. O artigo é amparado pelas discussões, temas e conceitos abordados por Sara Ahmed nas obras Vivir una vida feminista (2018) e Complaint! (2021). Os dados coletados e analisados são da pesquisa quantitativa realizada no início de 2020, via plataforma GoogleForms, com 121 estudantes da UNESP de Marília. As análises apresentadas neste artigo, demonstram como os movimentos estudantis de estragas-prazeres da UNESP-Marília, se tornaram protagonistas no combate às recorrentes violências no campus, devido à falta de canais institucionais consolidados de suporte legítimo e de confiança para as vítimas. Portanto, as coletividades realizam de forma efetiva o “ouvido feminista”, a integração e acolhimento de estudantes, ao mesmo tempo que evidenciam e confrontam todas essas problemáticas no ambiente universitário.
Decolonizando o olhar

Published: November 2022

A universidade tem se mostrado um local de formas de violências relacionadas ao gênero e suas interseccionalidades que atinge alunas, alunos e alunes. Para dar visibilidade a essas agressões, estudantes das três universidades públicas estaduais paulistas (UNESP, USP e UNICAMP) estão se mobilizando e criando coletivos em redes sociais digitais onde compartilham textos e imagens - produzidas ou repostadas de outras fontes - cujo intuito é revelar sua luta em construir espaços acadêmicos livres de discriminações. O objetivo é analisar essas peças visuais – ilustrações e fotografias - criadas para as plataformas Facebook e Instagram, a fim de compreender se essas imagens têm a intenção de “decolonizar o olhar”, isto é, se desconstroem as lógicas colonialistas de percepção dos corpos, dos gêneros e das sexualidades. Esta pesquisa está baseada no conceito de decolonização do olhar, conforme descrito pelos autores latino-americanos Barriendos (2019), Léon (2012) e Schenkler (2019; 2017;2016; 2012).

O objetivo deste artigo foi identificar os riscos das funções desempenhadas pelos colaboradores em uma mineração de diamantes e sugerir melhorias em relação à Saúde e Segurança dos funcionários. A metodologia consistiu na antecipação, identificação e classificação dos fatores de risco e sugestão de medidas de controle. Todas as funções desempenhadas apresentaram algum tipo de risco (físico, químico, biológico, ergonômico e de acidentes) inerente à sua atividade e, consequentemente, medidas de controle foram sugeridas para cada um dos riscos. Os funcionários do administrativo apresentaram apenas riscos ergonômicos (má postura, trabalho repetitivo e barulho excessivo). As demais funções analisadas apresentaram mais riscos, semelhantes e classificados em físicos (ruído, calor e vibrações), químicos (material particulado), biológicos (vírus, fungos e bactérias), ergonômicos (má postura, trabalho repetitivo e barulho excessivo) e de acidentes (equipamentos de proteção individual inapropriados, máquinas sem proteção, queda de pessoas, choques elétricos, tombamento e deslizamento dos equipamentos).

Aim: To analyze rehabilitation and improvement of the quality of life of patients with median abdominal wall defects (MAWD) by increasing the efficiency of alloplasty by determining the general principles of planning and performing surgical interventions.
Materials and methods: We carried out an analysis of the treatment results of 346 patients with MAWD, who underwent surgery in the 1st Poltava City Hospital for the period 2005-2019. There were 269 women (77.8%), men – 77 (22.2%). 282 (81.5%) patients underwent reconstructive surgeries, 59 (17.1%) – reconstructive and corrective alloplasty techniques, and 5 (1.4%) – corrective ones. Patients underwent surgery: onlay – in 3 patients (0.9%), sublay – in 289 (83.5%), sublay-inlay – in 38 (11.0%), inlay – in 4 (1.2%), Ramirez modification – in 10 (2.9%), open IPOM – in 2 (0.6%).
Results: Local complications were in 25 (7.2%) cases: seroma in 12 (3.5%) patients, infiltrate in 5 (1.5%), necrosis of the edges in 4 (1.2%), hematoma – in 3 (0.9%), wound suppuration – in 1 (0.3%). In the remote period, 14 (4.1%) were registered: recurrence – 7 (2.0%); long-term deep seroma- 3 (0.9%); ligature fistulas with phlegmon – 2 (0.6%); abscess formation – 1 (0.3%), hernial sac infiltration – 1 (0.3%).
