La transdisciplinariedad como eje transversal de la docencia universitaria: un constructo transmetodológico contra – resistencia
Authors: Rodriguez Milagros Elena
Published: July 2021

La investigación rizomática desde la deconstrucción como transmétodo sustenta la transdisciplinariedad como eje transversal de la docencia universitaria, un constructo transmetodológico contra – resistencia, objetivo complejo de investigación. Se deconstruye indisciplinando las disciplinas en las universidades; para  interpelar al sujeto objeto en la docencia-investigación; para luego en una reconstrucción esperanzadora vamos a transversalizar la transdisciplinariedad en la docencia universitaria que anida una Educación Decolonial Transcompleja, profundamente inclusiva que atiende a procesos complejos del ser humano y su conformación como ciudadano del mundo en una decolonialidad planetaria, que propende transmetodologías con transmétodos que complejizan los métodos, como la investigación transdisciplinar critica y la investigación acción participativa compleja.

Published: July 2021

Este trabajo pretende comprender cómo las mujeres de la Casa Cultural del Chontaduro resignifican sus experiencias de diversos hechos o situaciones de violencia a través del arte con la valoración de elementos simbólicos propios de su identidad social y cultural. De esta manera, se utilizó una metodología cualitativa donde se realizaron entrevistas semiestructuradas a tres mujeres de la Casa Cultural del Chontaduro con el fin de conocer estas experiencias desde sus propias narrativas e interpretarlas a través de la teoría de la psicología social. Se encontró que un libro, ciertas canciones, poemas, instrumentos musicales y vestuarios son elementos simbólicos para las mujeres de la Casa Cultural del Chontaduro, los cuales sirven como mediadores en el proceso de resignificación y contribuyen a una afirmación de la identidad social y cultural.
Interfacing participation in citizen science projects with conversational agents
Authors: Portela Manuel
Published: July 2021

This paper assesses the use of conversational agents (chatbots) as an interface to enhance communication with participants in citizen science projects. After developing a study of the engagement and motivations to interact with chatbots, we explored our results. We based our analysis on the current needs exposed in citizen science literature to assess the opportunities. We found that chatbots are great communication platforms that can help to engage participants as an all-in-one interface. Chatbots can benefit projects in reducing the need for developing an exclusive app while it can be deployed on several platforms. Finally, we establish design suggestions to help citizen science practitioners to incorporate such platforms to new projects. We encourage the development of more advanced interfaces through the incorporation of Machine Learning to several processes.
One-step preparation of TiO2–carbonized medium-density fiberboard for volatile organic compound photodegradation
Authors: Lee Min , Park Sang-Bum , Mun Sung-Phil
Published: July 2021

Photocatalytic carbonized medium density fiberboard (MDF) was prepared by one-step carbonization with titanium tetraisopropoxide (Ti-tip) as a TiO2 precursor. Anatase TiO2 was formed at carbonizing temperatures of 600 to 800 °C. However, at > 900 °C, most crystalline TiO2 was rutile. Ti-tip-treated carbonized MDF (c-MDF) showed outstanding formaldehyde reduction performance with complete removal of formaldehyde from the chamber in 1 to 3 days. However, with non Ti-tip-treated c-MDF, formaldehyde remained after 20 days. No toluene was detected after 3 h on 50% Ti-tip-treated c-MDF, while toluene was continuously detected with other samples (10% and 5% Ti-tip-treated c-MDF, and untreated c-MDF). After 9 h ultraviolet exposure, toluene was completely reduced on 10% and 50% Ti-tip-treated c-MDF; reduction was only 20% on untreated c-MDF. In addition, c-MDF/TiO2 prepared at 800 and 900 °C had significantly higher photocatalytic performances compared to those obtained at lower carbonization temperatures. Based on the results, the combination of 10% Ti-tip treatment and carbonizing at 800 °C provided the optimum photodegradation capacity for formaldehyde and toluene.
Analysis of deterioration characteristics in oil-immersed insulation pressboard with different durations of aging based on an image-processing method
Authors: Wang Yongqiang , Fei Ruoyu , Feng Changhui , Shang Jing
Published: July 2021

Insulation pressboard samples were obtained by thermal aging (according to Montsinger’s formula, at 130 °C, the pressboard is heated for 0 to 32 days) and discharge experiments. SEM images of samples were analysed. Image segmentation was applied to calculate the fibre width, cross-sectional porosity, and carbon-trace area. Inter-layer fibre models were established to observe fibre morphology using 3-D reconstruction. The initial discharge voltage decreased with age, and the discharge amounts increased. After 16 days of aging, the fibre width had decreased to between 68.1% and 81.8% of unaged pressboard. As the aging increased, cellulose hydrogen bonds were broken, which affected the expansion of interlayer pores, increasing the porosity of the pressboard. After 32 days of aging, the porosity increased to 2.38 times that of a new pressboard. In addition, the longer the aging, the larger the area of carbon marks caused by the discharge breakdown. With the aggravation of thermal aging, the insulating property of pressboard decreased due to the decrease of fibre width and increase of porosity that further accelerated the damage to the fibre structure. It was concluded that the fibre width and porosity could be used as criteria to judge the degradation of pressboard.

Solution for the Multigroup Neutron Space Kinetics Equations by Source Iterative Method
Authors: Tavares Matheus Gularte , Claudio Zen Petersen  , Marcelo Schramm  , Rodrigo Zanette
Published: July 2021

In this work, we used a modified Picard’s method to solve the Multigroup Neutron Space Kinetics Equations (MNSKE) in Cartesian geometry. The method consists in assuming an initial guess for the neutron flux and using it to calculate a fictitious source term in the MNSKE. A new source term is calculated applying its solution, and so on, iteratively, until a stop criterion is satisfied. For the solution of the fast and thermal neutron fluxes equations, the Laplace Transform technique is used in time variable resulting in a first order linear differential matrix equation, which are solved by classical methods in the literature. After each iteration, the scalar neutron flux and the delayed neutron precursors are reconstructed by polynomial interpolation. We obtain the fluxes and precursors through Numerical Inverse Laplace Transform by Stehfest method. We present numerical simulations and comparisons with available results in literature.

Herpes simplex virus type 2 is the common cause of genital ulcer disease worldwide. Genital herpes infection is a major concern in pregnancy due to the risk of neonatal transmission. Materials and methods: A descriptive cross-sectional survey was conducted from August 2016 to March 2017 in some hospitals and health centers to assess the seroprevalence and risk factors of herpes simplex virus type 2 infection among pregnant women attending antenatal care in Dhamar city, Yemen. After taking written consent, socio-demographic, behavioral and obstetric history along with blood samples were collected from 200 pregnant women using a pre-structured questionnaire. Sera were analyzed for HSV-2 specific IgG using Electro-Chemiluminescence Immunoassay (ECLIA) method. Results: The overall seroprevalence of HSV-2 infection was 6 % (12/200) among pregnant women in Dhamar city. Levels of education and some obstetrical history such as numbers previous abortion (P=0.03), stillbirth (P=0.001). Although the study showed, there are significant differences in some symptoms, such as itching (P=0.02) and inflammation during urination (P=0.03). Conclusion: Overall, the seroprevalence of HSV-2 infection among pregnant women in Dhamar city is low. There is a critical need to adopt screening of HSV-2 into the antenatal profile tests. There is also need for more health education of this virus infection, methods of transmission, associated risk factors, and effective prevention and control strategies.

Authors: I Maslarski , V Stoikov , G Ingilizova
Published: July 2021

The COVID-19 pandemic has had profound impacts on medical education globally. Worldwide, most medical students have missed months of educational experience that is considered fundamental in their training. Advances in technology are a potential solution to the problem. Forms of interactive learning, use of online platforms, as well as variants of e-lecture teaching are considered as alternatives to in-person teaching, as a part of a modernized anatomy curriculum. In addition to the already widespread online meeting platforms, we also discuss the use of video recordings with integrated slides, real pictures and short videos which can be uploaded onto the university platform Moodle. Alternatives to dissections, prosections, plastination, microscopy and videos are considered as potential forms of organization in the learning process. In regards to dissections, the problem of acquiring practical skills in an environment of social distancing and the successful accomplishment of tests and exams is also discussed.

Non communicable diseases (NCDs) are the group of diseases which remain restricted to the affected person only. Various diseases like Atherosclerosis, Myocardial infarction, COPDs, Diabetes, Obesity etc are included in NCDs. According to Unani system of medicine replenishment to the body is provided by Quwwat Ghādhiya (Nutritive faculty) and its four assisting Quwā i.e Quwwat Jādhiba (Absorptive faculty), Quwwat Māsika (Retentive faculty), Quwwat Hāḍima (Digestive faculty) and Quwwat Dāfi‘a (Expulsive faculty). These Quwā are served by Kayfiyāt Arba‘a (Four qualities) i.e Ḥarārat, Burūdat, Ruṭūbat and Yubūsat. So any deviation in these Kayfiyāt Arba‘a may lead to NCDs. NCDs are endogenous in origin and their causes may primarily or secondarily be related to the diet. The diet is never absolute. During Haḍm ‘Uḍwī , Quwwat Ghādhiya takes only required nutritive substances from it and remaining parts are excreted from the body in the form of Fuzlat (waste materials). The nature and duration of NCDs depends upon the nature of these Fuzlat. When Fuzlat accumulate in any organ, swelling may result e.g Waram al-Kabid (Hepatic swelling). Ṭabī‘at may divert the fuzlat to other organs of the body to decrease the Imtilā (Congestion) and protects the body from harmful effects. Various skin disorders like Taqashshur al-Jild (Psoriasis), Mental disorders like Sahr (Insomnia), Mālankhūliya (Melancholia) etc are because of Fuzlat and are included in NCDs.
Placenta accreta spectrum disorders in pregnancies following in vitrofertilization
Authors: Slavov Sergei
Published: July 2021

Placenta previa and related pregnancy complications are more common in In vitro fertilization pregnancies compared with spontaneous ones. There is evidence that PAS disorders are more common in pregnancies after IVF. Factors leading to a higher incidence of this pathology in IVF pregnancies have not been fully studied. Possible causes are the advanced age of women undergoing IVF, factors related to infertility itself, causes from the biological part of the In vitro procedure or controlled ovarian stimulation. The study of these factors is crucial for clinical practice as it would improve the outcome of IVF pregnancies.

A língua inglesa na escola sob o ponto de vista de alunos e professores
Authors: Eidelwein Marina Hofstätter , Mottin Lívia Pretto
Published: July 2021

Considerando o inglês como um idioma que tem assumido um papel cada vez mais importante no mundo globalizado em que vivemos, faz-se necessário avaliar de que forma essa língua tem sido vista e, consequentemente, ensinada nas escolas. Desse modo, o presente artigo analisa pontos de vista de alunos e professores sobre a língua inglesa, bem como implicações didático-metodológicas do ensino da língua em sala de aula, com base em entrevistas não dirigidas semiestruturadas com professores de inglês e com alunos do terceiro ano do ensino médio de duas escolas públicas estaduais do Vale do Taquari, no Rio Grande do Sul, Brasil. Os resultados apontam que a língua inglesa tem sido vista como uma língua franca global, possível de ser utilizada em diferentes contextos comunicativos como língua adicional, trazendo muitos benefícios aos falantes e, por conseguinte, fazendo com que o interesse por sua aprendizagem aumente. No entanto, constatou-se que a metodologia adotada nas escolas não proporciona o desenvolvimento das habilidades necessárias para que esse idioma seja colocado em uso, sendo esse um fator preponderante para a desmotivação dos estudantes, que não veem razão para estudar regras gramaticais de forma descontextualizada e repetitiva. Sinaliza -se, portanto, que o ensino de inglês na escola precisa estar voltado para o desenvolvimento de projetos baseados em tarefas que busquem proporcionar aos estudantes situações reais de uso da língua, através das quais seja possível o desenvolvimento de uma competência linguística voltada para o princípio da inteligibilidade.

Published: July 2021

A fructose-rich diet has been known to cause metabolic syndrome effects such as body weight gain, increased blood pressure, blood lipids and glucose levels. The role of voluntary physical activity in these alterations is not known clearly. The aim of this study was to investigate the possible improving effects of voluntary physical activity in rats that were feeding with a fructose-rich diet.
Spraque-Dawley female rats were separated as control (C;n=7), voluntary physical activity (A;n=7), fructose (F;n=7) and fructose+activity (F+A;n=7) groups. A and FA groups were kept in cages with running wheels during six weeks. F and FA groups were fed with adding 20% fructose in drinking water. Body weight was measured weekly and Lee Index was used to determine obesity. At the end of the feeding period serum glucose, insulin and lipid levels were measured by enzymatic method and blood pressure was determined with the tail-cuff method.
Daily voluntary walking distance in F+A and A groups were similar during six weeks. Fructose intake induced to increase systolic blood pressure (p=0.001), diastolic blood pressure (p=0.002), glucose (p=0.041), insulin (p=0.001), cholesterol (p=0.001), triglyceride (p=0.001) and liver weight (p=0.035). The voluntary activity was found effective on the decrease of weight gain (p=0.018) however we did not observe a significant effect on blood pressure (p=0.917) and insulin resistance (p=0.565) following the fructose-rich diet.
We conclude that voluntary activity has preventive effect on obesity but may not to be effective on increased blood pressure and insulin resistance in female rats which were feeding fructose-rich diet during six weeks.

Authors: Lukanov H. , Pavlova I. , Genchev A.
Published: July 2021

A study was conducted to establish the possibilities for replacing 5 and 10% of wheat in the combined feed for domestic quails with extruded bakery waste and to study its impact on the growth and productivity of quails. 270 domestic quails from the specialized meat production line WG were included in the experiment and divided according to the principle of analogues into 3 aligned groups: control, fed with mixtures without the inclusion of extruded waste from bakeries; experimental I, in the mixtures of which 5% of the wheat was replaced with extruded bakery waste and experimental II, in which 10% of the wheat in the mixtures was replaced by extruded bakery waste. The experiment continued until the age of 35 days. The following signs were monitored: mortality (%), live weight (g), average daily weight gain (g), feed consumption (g), feed conversion (kg/kg weight gain). The study showed that for the 35-day period, the quails from the specialized meat production line WG consumed an average of 812-817 g of compound feed, with an average increase of the weight gain 255-258 g. Under these conditions, the average feed conversion ratio is in the range of 3.15-3.20. In the course of the trial it was found that the replacement of 5 and 10% of wheat in the feed mixture with extruded bakery waste reduces the value of compound feed by an average of 0.85 and 1.7%, but does not affect the studied productivity traits and economic indicators from fattening. When summarizing the results for the 35-day period, the differences between the control and experimental groups on the studied productive traits are less than 2%, and the difference in the value of 1 kg weight gain between the groups is less than 1%.

Published: July 2021

Conocer el efecto de productos antimicrobianos y antagonistas sobre el crecimiento de fitopatógenos es de relevancia en la agricultura al integrarlos como estrategia de control en campo o invernadero. El objetivo de este trabajo fue analizar el crecimiento y antagonismo in vitro de Trichoderma parareesei y Fusarium oxysporum sobre diversas concentraciones de quitosan (1, 4, 6, 8, 10, y 12 mg • mL-1). Estas mismas dosis fueron suplementadas con metabolitos de T. parareesei filtrados en papel celofán adherido al medio de cultivo sobre el cual se creció el fitopatogeno. La difusión de metabolitos en cada dosis fue evaluada antes de incorporar a F. oxysporum. Los resultados del análisis estadístico mostraron diferencia significativa entre el crecimiento e inhibición de los hongos sobre quitosan (F5,35 = 4.47, P<0.001), la dosis de 1 mg • mL-1  indujo  mayor crecimiento de micelio en el fitopatogeno, disminuyendo conforme incrementó la dosis de quitosan. Para el caso T. parareesei las dosis utilizadas no limitaron su desarrollo y crecieron 93 % mas que F. oxysporum, y la mayor inhibición para ambos casos fueron  6 y 12 mg • mL-1. El área de difusión de metabolitos de T. parareesei se incrementó en relación a la dosis de quitosan evaluada, y aunque esta no tuvo relación con la reducción del crecimiento de F. oxysporum, hubo un efecto sinergista entre el quitosan y metabolitos secundarios.
Inferring the thermomechanical state of the lithosphere using geophysical and geochemical observables
Authors:   , Shinevar William J.
Published: July 2021

This thesis focuses on interpreting geophysical and geochemical observables in terms of the thermomechanical state of the lithosphere. In Chapter 1, I correlate lower crustal rheology with seismic wave speed. Compositional variation is required to explain half of the total variability in predicted lower crustal stress, implying that constraining regional lithology is important for lower crustal geodynamics. In Chapter 2, I utilize thermobarometry, diffusion models, and thermodynamic modelling to constrain the ultra-high formation conditions and cooling rates of the Gore Mountain Garnet Amphibolite in order to understand the rheology of the lower crust during orogenic collapse. In Chapter 3, I interpret geophysical data along a 74 Myr transect in the Atlantic to the temporal variability and relationship of crustal thickness and normal faults. In Chapter 4, I constrain the error present in the forward-calculation of seismic wave speed from ultramafic bulk composition. I also present a database and toolbox to interpret seismic wave speeds in terms of temperature and composition. Finally, in Chapter 5 I apply the methodology from Chapter 4 to interpret a new seismic tomographic model in terms of temperature, density, and composition in order to show that the shallow lithospheric roots are density unstable.

En los últimos tiempos ha tomado relevancia el tema ambiental, debido a los sentidos estragos del calentamiento global producido por el cambio climático; y sí, esto es una realidad palpable y una gran preocupación de la comunidad científica a nivel mundial, puesto que repercute en el bienestar humano en todos los aspectos. Por esta razón vale preguntarse cuál será el futuro de la humanidad si no se hacen los correctivos necesarios, que no solo es “plantar un árbol”, como dicta el eslogan de moda, es también concienciar a la población en cuanto al uso de los recursos naturales; ¿de qué manera? Cabe decir que esta interrogante ha sido muy fácil responder, pero hacerla realidad es complicado por el empeño del ser humano en abusar de su entorno.

Objetivo: El objetivo de esta investigación fue determinar la confiabilidad de instrumento sobre capacidades cognitivo-prácticas necesarias para el tratamiento de mínima intervención de la caries dental en la Carrera de Estomatología.

Métodos: Estudio piloto que describe en qué medida un instrumento previamente diseñado es comprensible y funcional. La muestra estuvo integrada por 52 profesores de la carrera de estomatología. La información fue recogida en dos etapas, una prueba en la que se aplicó el instrumento y trascurridos 15 días se realizó una segunda prueba. Las variables consistieron en 21 ítems resultantes del diseño y la validación previa. Se calculó la media de variabilidad para cada ítem en el momento de la prueba y la segunda prueba, la consistencia interna a través del alfa de Cronbach, una comparación de la media de los ítems del instrumento según t de Student y se calculó el coeficiente de correlación intraclase.

Resultados: La prueba y segunda prueba mostraron valor de las medias totales de 2,43 y 2,47 respectivamente, expresando que los objetivos del instrumento se logran parcialmente. Las puntuaciones mostraron buena coherencia (alfa de Cronbach 0,817 y 0,801 en prueba y segunda prueba). La prueba de hipótesis al ser t ≤0,05 en ambos momentos se acepta que todos los ítems se relacionaron.

Conclusiones: Se demostró la confiabilidad en lo que se refiere a la consistencia interna y estabilidad temporal en cada uno de sus ítems.

The study was conducted to explore the spider diversity in different plantations of Western Ghats Wayanad, Kerala state, India. The investigation was carried out for the period from February 2019 to February 2020. A total of 100 species belonging to 74 genera under 20 families were recorded from the selected habitats. This represents 51% families recorded from the Western Ghats, Kerala. The highest species richness was found in the coffee plantation (site A) with 56 species belonging to 12 families. The tea plantation (site B) recorded 27 species belonging to 11 families. The rubber plantation (site C) showed the lowest species richness with 17 species belonging to ten families. Guild structure analyses of the collected spiders revealed nine functional groups viz.., orb-web builders, stalkers, ambushers, cob-web builders, ground runners, foliage runners, tent web builders, sheet-web builders and funnel web builders. The pattern and the architecture of webs varied among different families. During the period of study, five different web patterns were recorded- orb web, tent web, cob web, sheet web and funnel web. It is concluded that the structure of the vegetation is expected to influence the diversity of spiders in different plantations.
Fires in nature: a review of the challenges for wild animals
Authors: GUTIÉRREZ JARA , De Miguel Javier
Published: July 2021

Animals living in the wild are exposed to numerous challenges, such as fires, that can lead to suffering. The impacts of fire have been studied in different branches of ecology, but studies of its effects on the welfare of individual animals remain scarce. The current review aims to synthesize a sample of relevant aspects regarding fire’s negative effects on wild animals. We mainly focus on the immediate impacts of fire on individuals. How animals respond to fire depends on many factors including their life history, evolutionary adaptations to fire, and individual stress coping styles, in addition to the characteristics of the fire.

The fundamentals of carrying out future work for animal rescue and prevention of animal harms in fires were also explored. Fires may increase the risk of injury, disease, stress, and mortality for animals living in the wild, resulting in physiological and psychological harm, experiences of suffering, discomfort and pain, and long-term detrimental consequences. Wild animals can benefit from effective rescue, rehabilitation, and release during fires, and post-release monitoring must accurately evaluate their outcome success. The resulting information can be used to educate veterinarians, rehabilitators, and the public in the prevention of the suffering and deaths of as many animals as possible in future fire events, which ultimately benefits animal welfare. This review provides a better understanding of how fire compromises animal welfare, providing an example of how to use the knowledge gathered in animal ecology to examine the welfare of wild animals. It can help raise concern for the situation of wild animals as individuals, and to develop the field of welfare biology, by identifying promising future lines of research.

A single-pass and multi-pass compression experiments with a Ti-6Al-4V alloy fabricated with hot isostatic pressing (HIP) were carried out on a Gleeble-1500D simulator. The true stress-strain curve, microstructure and microhardness of the alloy deformed at a total strain of about 70 % were studied. The results show that the stress value increased as the strain rate increased during each deformation pass and the same was true for the single pass. At the initial deformation stage, the flow stress increased rapidly with the increase in the strain until it reached the peak; then it showed a different softening extent, which was more obvious for the three-pass deformation than for one-pass and two-pass deformation. During the multi-pass deformation, the lamellar α phase was mainly distorted, but during the one-pass and two-pass deformation, it was bent; the spheroidisation of the lamellar α phase mainly occurred during the three-pass deformation, significantly increasing the extent of softening. Meanwhile, the degree of the spheroidized α phase and the volume fraction of β-transformed phase (βt) increased as the strain rates increased. Finally, a tri-modal microstructure, including the β-transformed phase (βt), lamellar α phase and equiaxed α phase was obtained during three-pass deformation. In the process of multi-pass deformation, the microhardness increased with the increase in deformation passes. When the strain rate was 1 s–1, the microhardness increased from 299.5 HV and 309.1 HV to 342.6 HV with the increase in deformation passes. It was also found that the microhardness increased with an increase in the strain rate under a certain amount of deformation.

Published: July 2021

Prussian blue (PB) has attracted substantial attention as a potential adsorbent for radionuclides due to its high water-insoluble characteristics. Here, PB-encapsulating activated carbon fibers (ACFs) obtained via a physicochemical in-situ synthesis were introduced for an effective cesium removal. ACFs were used as an anchor platform to hold PB within the pores. The physicochemical synthesis of PB (PB-ACF-B) was done by stirring ACFs in an iron chloride solution. Potassium ferrocyanate was injected during the stirring process. As the counterpart, powdered PB (PB-ACF-A) was prepared with a physical synthesis. Throughout the test, PB-ACF-B revealed a decrease in the specific surface characteristics compared to PB-ACF-A; however, it also experienced an increase in the 133Cs adsorption. In all the cases, the dosage of the absorbent and radionuclide was in positive correlation with the adsorption performance. Further, the amount of PB was found to be the key factor for the adsorption of 133Cs compared to the specific surface characteristics.

The combination of imaging and therapeutic agents with drug nanocarriers has received great attention due to the number of outstanding applications in nanobiology and nanomedicine. In this respect, the traditional and biocompatible magnetic nanoparticles, such as Fe3O4, play a pivotal role, having a versatile potential in imaging diagnostics, treatments and targeting in drug-delivery systems. In this work, we report on Fe3O4 nanoparticles functionalized with quercetin molecules and show that the conjugation between Fe3O4 nanoparticles and quercetin significantly modifies the fluorescent properties of the nanocomposite. The obtained results offer a reliable tool for image-assisted drug-delivery systems, targeting and penetrating such a delicate area of the human body as a blood-brain barrier.

Published: July 2021

In the annealing of some pure metals and various alloys, the phenomenon of accelerated oxidation is known, which is due to the fact that the resulting surface oxides fail to inhibit or completely stop the oxidation process. Vanadium ferrous alloys are rapidly oxidized during high-temperature annealing in oxygen atmospheres. The rate of oxidation is so great that it is considered a catastrophic oxidation. In this work, the AISI M4 alloy was investigated. The mechanism and model of the oxidation of alloy AISI M4 were developed on the basis of an analysis of the oxidation in a temperature range of 700–1000 °C. The holding time was 6 h. The alloy was analysed with an optical microscope and scanning electron microscopy equipped with EDS, WDS and EPMA detectors. It was found that below 850 °C, molten oxide is formed, which is predominantly of V2O5 composition. Above 850 °C, the oxide layer is multi-layered. The oxide layer consists of complex oxides, which formed with other elements. The X-ray analysis confirmed the presence of the following oxides in the oxide layer: Fe2O3, Cr2O3, FeVO4, V2O3 and Fe2WO6; and the second oxide may additionally be: V2O5, Cr2O5 and FeWO4.

В статье представлены результаты опроса экспертов, проведенного в январе-феврале 1996 г. с целью выявления мнений специалистов по ряду принципиальных вопросов, касающихся контроля рождаемости в России. Данное исследование было частью исследовательского проекта «Планирование семьи и политика общественного здравоохранения в России: переход от аборта к контрацепции в меняющемся обществе», выполнявшегося Институтом международных исследований семьи (Москва) в 1995-1997 гг. Всего было опрошено 89 экспертов, представлявших научные круги исследователей из различных областей знания (география, демография, история, психология, медицина, философия, экономика), организаторов здравоохранения и практикующих врачей, депутатов Государственной думы, представителей федеральных и региональных органов исполнительной власти и священников. Программа опроса охватывала вопросы легитимности и моральной приемлемости аборта, оценку действующего законодательства об искусственном прерывании беременности, оценку допустимости людьми регулирования репродуктивной функции и наиболее приемлемых способов контроля рождаемости в контексте тенденций рождаемости в стране, оценку деятельности общественных организаций, выступающих за ограничение и запрещение аборта по желанию женщин и возможных последствий изменения законодательства по отношению к аборту и планированию семьи. Подавляющее большинство опрошенных экспертов поддержали безусловное право женщин решать судьбу своей беременности. Законодательный запрет абортов и ограничение права женщин на прерывание беременности по их желанию, по мнению экспертов, не решил бы проблемы низкой рождаемости и мог бы иметь только отрицательные последствия с точки зрения повышения уровня криминогенности в стране и ухудшения состояния здоровья женского населения. Спустя четверть века вопросы, затронутые в исследовании середины 1990-х, остаются по-прежнему актуальными.
