The aim: To reveal the effect of pyrophosphates on the tooth germ structure in the mandible of embryos (17th day of pregnancy) gestated by females, kept on a pyrophosphate-rich diet since 30 days before fertilization to gestation.
Materials and methods: The effect of food supplements was studied in «Overload phosphates model». Experiments were carried out on white nonlinear outbred mice with mass 25-28g (n= 40). The females from the control group were fed with standard rodent food, whereas the experimental females were fed with pyrophosphate-enriched food. The material for the morphological study were the mandible of 17-day-old mouse embryos (E-17), which were examined under a microscope with subsequent photofixation.
Results: The examination of the mandible of 17-day-old mouse embryos, gestated by females on a pyrophosphate-rich diet, showed morphological changes in tooth germs at the dental follicle development stage.
Conclusions: The experimentation revealed that the pyrophosphate excessive intake during dental follicle development leads to early dentinogenesis and oppression of ectodermal structures of tooth germs.

Published: March 2022

The aim: To assess morphometric parameters of placentas and to evaluate the correlation between the placental disk shape, the site of the umbilical cord insertion and the birth weight of dichorionic twins.
Materials and methods: The geometry of placentas, distances between umbilical cord insertion sites and the centroids of the disks were measured in 135 pairs of dichorionic diamniotic twins. The impact of the above-mentioned parameters on the birth weight and placental mass was analyzed.
Results: In terms of weight and geometric parameters of placentas, no proven discrepancy between different types of twins and inside pairs was found. A strong correlation was established between the placental weight and birth weight (r = 0.71, p < 0.05). Both the placental weight and birth weight showed the strong correlation with S*Circ (r = 0.62, p < 0.05). The displacement of the umbilical cord insertion site from the centroid of the placenta was negatively correlated with its mass (r = -0.428, p < 0.0001) and birth weight (r = -0.6115, p < 0.0001). The displacement along the maximum axis proved to play a significant role.
Conclusions: In dichorionic diamniotic twins, the area of the placentas plays the determining role in the functional activity of the organ, which increases when its shape approaches the circle. The area of the placenta multiplied by its circularity had the strongest correlation with birth weight and placental mass. The farther from the centre the umbilical cord is inserted, the lower the functional capacity of the placenta is.

The aim of the study was on the basis of the study of clinical manifestations and mechanisms of the formation of disorders of psychological adaptation among the combatants, to develop the principles and program of their medical and psychological rehabilitation.
Materials and methods: The study was attended by 153 people at the sanatorium and resort stage of treatment, of which 98 people were combatants and 55 people were civilians. The study used a set of methods aimed at the study of emotional disorders (HDRS, BDI, Spielberger Scale, “Asthenic state scale”), individual psychological features (Multilevel personal questionnaire “Adaptability,” Test questionnaire G. Shmishek, K. Leonhard), features of psychosocial functioning (Mississippian scale of PTSD-military version) and quality of life (WHOQOL-BREF).
Results: At the stage of sanatorium treatment of combatants is important readaptation to peaceful living conditions. A clinical and psychological analysis of combatants showed that the presence of experienced state of subjective distress and emotional disorder leads to a decrease in the productivity of adaptation to a stressful event. The stress factor disrupted the integrity of the micro-social network of combatants and their system of social support and social values, with the prevailing sense of inability to overcome problems and build plans. A detailed analysis of the nature of depressive and anxiety manifestations was carried out, which allowed to determine the predictors of the violation of adaptation in combatants.
Thus, on the basis of the study of clinical manifestations and mechanisms of the formation of disorders of psychological adaptation among the participants of hostilities, the principles of their medical and psychological rehabilitation at the sanatorium and resort stage of treatment are developed.
Conclusions: The peculiarities of stress response in combatants as a component of personal potential play a role in the formation of predictors of psychological adaptation disorders among combatants. Psychological intervention at the tertiary stage of rehabilitation (sanatorium-resort) should be targeted, taking into account individual-psychological characteristics (preventors) and psychosocial factors (predictors)

Published: March 2022

Methodological foundations of nuclear medicine in pediatrics are analyzed on the basis of literature data and personal experience. The main directions of radionuclide diagnostics and radionuclide therapy in children are briefly considered. The importance of accurate determination of the optimal value of the activity of a specific radiopharmaceutical administered to a child, considering his body weight and the study protocol, was noted. A tendency to an increase in the radiation load on patients is shown due to the widespread introduction into clinical practice of hybrid installations for radionuclide studies, when using which the dose of internal radiation from radiopharmaceuticals is supplemented by the dose of external radiation from X-ray CT. The need to consider the risk of radiation-induced carcinogenesis during nuclear medical procedures, the likelihood of which in children is significantly higher than in adults, is emphasized. The technological and psychological features of these procedures in children are discussed. The necessity of revision of domestic normative documents regulating the use of means and methods of nuclear medicine in pediatrics has been substantiated.

We present two patients with advanced unresectable intrahepatic cholangiocarcinoma successfully treated with combined systemic-regional chemotherapy. Intra-arterial treatment included oily chemoembolization and chemoinfusion (GEMOX) with additional systemic chemotherapy (GEMCIS). Chemotherapy did not stop after extrahepatic progression: metastases to the lungs and bones. Continuous symptomatic nutritional support allowed to minimize chemotherapeutic toxicity and to maintain good quality of life. One patient is still alive for more than 4 years, the other died of tumor progression in three years ten months. The importance of factors contributing to the long-term survival of patients with advanced intrahepatic cholangiocarcinoma is considered.

Published: March 2022

Despite being run by algorithms and data, the technology we use every day, often discriminates on the basis of race, gender, and even age. It is increasingly difficult to tell the extent to which the internet intersects with and amplifies male-centred technological innovations (AKA
Big Tech), heteronormativity, and intervenes in the functioning of democracy.
As technology's reach extends further into our everyday lives, we ask, what would a feminist internet look like?
 Feminist by Design offers methodological frameworks for feminist internet research,
creating a diverse platform for engagements, with reflections mainly from the Global South. These essays and analyses are steppingstones to a feminist internet—one that 'works towards empowering more women and people of diverse and marginalised sexualities and genders—in all our
diversities—to fully enjoy our rights, engage in pleasure and play, and dismantle patriarchy.'
 In this issue and more broadly in the field of feminist internet research, there is growing interest and trust in the rigour of feminist methodological inquiry and ways of knowing
to challenge a false narrative of the 'objectivity' of knowledge, especially in relation to science and technology. Placing the voices of those who were formerly margin- alised front and centre of internet research practices, this issue promises transforming and transformative accounts of
the world.
Feminist Internet Research Is Messy
Authors: McLean Nyx
Published: March 2022

Feminist internet research is messy and conducting meta-research on feminist internet research is even messier. This is a critically reflective article on the author's experience conducting a meta-research project on the feminist internet research methodologies and ethical frameworks
of the eight Feminist Internet Research Network (FIRN) research projects. The piece argues that the messiness of research is not something to shy away from but rather to embrace.
 Mess and messiness are that which are often cleaned up, hidden, discarded or outright ignored before,
during or after the research process. This article explores the messiness of conducting a meta-research project, reflecting on the research process; doing justice to the stories that are shared; and lastly, what critique means in light of feminist ethics of care. I put forward three recommendations
for engaging with mess in research: reflexivity; reaching out to others; and embracing messiness as care. This article is no way exhaustive but is a call to invite and bravely embrace the messy into the research process in order to elicit new knowledge.

Influence of the Material on Stress Distribution in Aesthetic Monolitic Complete Dental Crowns
Authors: Porojan Liliana , Topală Florin
Published: March 2022

The development of different materials for the use in posterior areas for aesthetic monolitic crowns has been a challenge in dental technology. The goal of this study was to develop 3D posterior teeth covered with complete aesthetic monolitic crowns and to compare the stress distributions under loads, revealing the effect of various materials on the biomechanical performance of the crowns. For the experimental analyses premolars and molars were chosen in order to simulate the biomechanical behaviour of the teeth restored with complete aesthetic monolitic crowns (zirconia, glass ceramic, composite). A static structural analysis was performed to calculate the stress distribution using the computer-aided engineering software. First principal stresses were recorded in the tooth structures and in the restoration for all these materials. Stresses recorded in the ceramic restorations are direct proportional with the elasticity of the material. Crowns made of materials with high elasticity (composite) show better behaviour for premolars then for molars, compared to ceramic materials. Stress values and distribution results can provide design guidelines for new and varied materials, regarding to the restored teeth.

Published: March 2022

Global energy demand and environmental concerns have stimulated increasing efforts to produce bioenergy and biofuels directly from renewable resources. The production of petroleum alternative compounds like bioplastics from abundantly available renewable materials in nature such as cellulosic and algal biomass through consolidated bioprocessing is an innovative approach. Here we show the production of bioplastics polyhydroxylkanotes (PHA) by consolidated bioprocessing using a bacterium with ability to degrade complex polysaccharides such as agarose and xylan without pre-treatment. The association of the bacterium in coculture with another bacterium dynamically enhanced agarose degradation and PHA production from xylan. Consolidated bioprocessing of complex polysaccharides to PHA investigated in this study opens up new avenues of employment of pure and co-culture for efficient production of PHA.

Published: March 2022

Due to the importance of the oxidation state in the classification of basaltic rocks many procedures have boon adopted for the adjustment of this parameter to minimize the effects of secondary oxidation. An appeal is made here to standardize this procedure and a case is made for the adoption of a value for the Fe203/Fe0 ratio of 0.15. It is probable that this is close to the original value in nature, at least for tholeiites.

Published: March 2022

Представлены результаты экспериментального исследования тушения метанола самовспенивающейся газоаэрозоленаполненной пеной (СГП). Цель экспериментов - определение критической интенсивности подачи пены при тушении метанола в резервуаре. Обоснованы размеры модельного очага пожара. Показано, что «жесткий» способ подачи СГП для тушения метанола неэффективен. При «мягком» способе подачи пены для тушения метанола критическая интенсивность составляет 0,11 л · с · м. Получены данные о температуре факела пламени метанола и плотности теплового потока на различных расстояниях от очага пожара.

Extinguishing polar liquids in tanks such as methanol is a complex task. Its successful solution depends on the fire size, the choice of foaming agent, the way of extinguishing solution supply. When extinguishing fires in tanks it is effective to use self-foaming gas-aerosol foam (SGF). In this work there are experimentally investigated the ways of SFS supply to extinguish methanol with «hard» and «soft» methods as well as the temperature of the methanol flame plume and the intensity of its radiation intensity are measured. To generate the foam there are used units UPAT-30 and UPAT-60 (self-contained solid fuel fire extinguishing units) with a capacity of 30 and 60 liters, respectively. To produce foam there was chosen the foaming agent “Nizhny Novgorod AFFF universal”. Foam expansion was 10, and foam stability was 40 minutes. The combustible agent is a complex inhibitor of hydroformation and corrosion which contains 99 % of methyl alcohol and 1 % of the anticorrosion additive IKT1. It has been shown that the «hard» method of extinguishing agent supply to the burning methanol mirror is ineffective. The «soft» extinguishing method, when foam is supplied to the side of the tank, allows to achieve confident fire extinguishing at a critical intensity of 0.11 l · m · s. When organizing the experiments there was carried out the justification of the minimum required size (in terms of area) of the combustion base. The most suitable is the base described in the standard UL 162. The extinguishing of methanol is significantly affected not only by the size of the combustion base but also by the thickness of the tank wall. When methanol burns, the temperature of the edge of the model fire base does not exceed 350 °C, and the temperature of the torch is close to 700 °C. This explains the fact that the heat flux density close to fire is much lower than during the diesel fuel burning (in 5-7 times). This fact should be taken into account when determining the extinguishing tactics for methanol as well as safe distances from the fire seat.
Absence of rigid polyurethane foam wall ignition from electric arc welding spark
Authors: Полетаев Николай Львович
Published: March 2022

Ствие случаев зажигания пенополиуретана, которое объясняется малым временем контакта искры с поверхностью пенополиуретана t. Приводятся экспериментальные оценки фактического значения t и минимально необходимого для зажигания пенополиуретана времени контакта с искрой t.

It is known that sparks of electric arc welding, representing drops of molten metal (hereinafter - iron sparks), have a high incendiary ability. However, due to a number of reasons, there is possible a situation when electric welding does not lead to the ignition of nearby combustible materials. The identification of such causes can have an important impact on the development of a standard method for investigating the ignition power of sparks. The work investigated the possibility of spark ignition of a vertical layer of rigid polyurethane foam installed on a laboratory table (hereinafter referred to as walls). The wall was exposed to sparks from electric arc welding with a power of up to 6 kW. The distance from the source of sparking to the wall was (15 ± 3) 10 m. A separate experiment lasted several minutes until the electrode burned out, the diameter of which varied from 2 mm to 4 mm. Research results and their discussion. In none of the experiments was it possible to ignite the wall with sparks. Sparks bounced off the surface of the polyurethane foam and fell down onto the horizontal surface of the laboratory table. To explain the results, an experimental estimate was made of the time t of the interaction of the drop with polyurethane foam and the minimum time t of such interaction, leading to the ignition of the wall. The estimate t < 30 · 10 s is based on frames of video recording with a frequency of 30 s of a luminous trail of a spark, curved by a collision with a wall. The estimate t > 1 s is based on simulated droplet exposure with small scale Bunsen burner flames of varying duration. Therefore, t << t. The reason for the lack of ignition of polyurethane foam was the short contact time of the electric arc welding spark with the surface of the polyurethane foam.

Published: March 2022

The northeast region has achieved remarkable growth in average literacy rate that is more than what the national average has achieved since the independent. However, the literacy rate cannot be justified for better elementary education. The extremely high dropout rate put the northeast region in danger of losing the track of achieving universal elementary education. Being the peripheral region of the country, the sole development of the education system relies largely on government funding. The pattern of government funding in the region is miserable. The large gap between plan and non-plan expenditure on elementary education as well as the negative growth of plan expenditure hinders elementary education development. The share of elementary education to the ratio of total expenditure on education keeps on decreasing. The impressive percentage share of expenditure on elementary education to the ratio of GSDP is misleading since GSDP of the northeast region is comparatively very small that portrays high percentage shares on education.
