Authors: Zabelina E. V. , Kozlova N. S. , Buzanov O. A.
Published: December 2023

Nominally pure lanthanum-gallium tantalate La3Ga5.5Ta0.5O14 crystals doped with aluminum, silicon and gallium oxide to above stoichiometric content have been grown by the Czochralski technique in iridium crucibles in argon and in agron with addition of oxygen atmospheres. The transmittance spectra of the crystals have been measured on a Cary-5000 UV-Vis-NIR spectrophotometer in the 200–800 nm range. Absorption spectra α(λ) have been plotted on the basis of the experimental data. The absorption spectra of the undoped crystals grown in an oxygen-free atmosphere have one weak absorption band at λ ~ 290 nm. The absorption spectra of the crystals grown in an agron with addition of oxygen have absorption bands at λ ~ 290, 360 and 480 nm. We show that for the crystals grown in an oxygen-free atmosphere, gallium doping to above stoichiometric content reduces the intensity of its only λ ~ 290 nm absorption band. Aluminum doping of the La3Ga5.5Ta0.5O14 crystals grown in an oxygen-free atmosphere significantly reduces the intensity of the λ ~ 290 nm absorption band and increases the intensity of the λ ~ 360 and 480 nm bands. Aluminum doping of the La3Ga5.5Ta0.5O14 crystals grown in an oxygen-containing atmosphere reduces the intensity of the λ ~ 360 and 480 nm bands and increases the intensity of the λ ~ 290 nm absorption band. Silicon doping of these crystals significantly reduces the intensity of the λ ~ 480 nm band and also reduces the intensity of the λ ~ 290 and 360 nm bands.

Published: December 2023

Apt-Alb-Cenomanian age rocks (K1a-al + K2s) within the northern part of the West Siberian oil and gas province (OGP) are the main commercial gas production target in the Russian Federation. However, at present there are certain prerequisites and significant reserves to increase the raw hydrocarbon base and gas production in the central regions of Western Siberia. For further study of the geological structure of these sediments in order to assess their oil and gas potential, it is necessary to set up and carry out complex geological, geophysical and special studies (including sedimentological identification of sediments, detailed reconstruction of paleogeographic sedimentation settings, paleofacial analysis of rocks, petrophysical support of the works). This will make it possible to increase the accuracy and reliability of the planned works on oil and gas prospecting and exploration, as well as to carry out a qualitative forecast of the area development of promising complex reservoir rocks, to perform a full calculation of the initial geological reserves of hydrocarbons for a number of new objects (including PK5, PK7, PK8) and to build highquality geological and hydrodynamic models of hydrocarbon deposits necessary for the design of their further development.A detailed analysis of the primary geological and geophysical materials at our disposal has shown that during the formation of the Pokur Formation in the Middle Ob oil and gas bearing area (OGO) there were heterogeneous conditions of sedimentation — from purely continental to coastal-marine. High lithologic and facies heterogeneity of the studied sediments is observed everywhere. These circumstances complicate the processes of detailed correlation in these sediments, and in some cases — unrealized in practice even within one exploration area. Stratification of productive strata is the most important part of oil and gas prospecting and exploration. According to the results of our studies, the upper strata are most well traced (in some cases up to the hypsometric level of PK3-4 strata occurrence). Their confident area correlation makes it possible to identify smaller stratigraphic subdivisions (packs) in these strata and to determine the paleofacial genesis of these sediments.

The history of prospecting and exploration of oil and gas fields within the Nepsko-Botuoba Anteklisa (NBA) and the eponymous oil and gas region (OGR) of the Leno-Tunguska Oil and Gas Province of the Siberian Platform dates back more than half a century. The base object of exploration for a long time remained the terrigenous deposits of the Venda reservoir. A number of large, medium and small hydrocarbon deposits are associated with them. The beginning of a systematic study of the northern regions of the Irkutsk region was the receipt of oil inflow from the Markov reference well in 1962. In 1971, the Yaraktinskoye gas condensate field was discovered north of Markovsky. In 1970, a parametric well was drilled within the Preobrazhensky uplift, which made it possible to identify a productive carbonate horizon (Zone B12), from which a gas inflow was obtained after hydrochloric acid treatment. Further continuation of the complex of geophysical studies east and south of Preobrazhenskaya Square made it possible to identify a number of positive structural forms. In the Chonsky zone, several local complications were identified — Chonsky, Molchalunsky and Verkhnechonsky structural noses, recommended for setting up area studies of MOU. The Preobrazhensky horizon (Zone B12) ranks second among the pay zones in terms of potential in-place reserves. It is the extremely low filtrationcapacitive properties of the natural reservoir and the harsh thermobaric conditions at the pressure of oil saturation with gas close to the initial reservoir pressure that is the basis for classifying these reserves as hard to recover (RHR).This article discusses the methodological features of drilling and completion of oil producing wells with a horizontal end of a long length, ascending inclined boreholes, multi-hole horizontal wells (MHW), conducting MHW, large-volume MKO and KGRP in the carbonate natural reservoir of the Preobrazhensky productive horizon (B12) of one of the fields of the Nepsky arch in the north of the Irkutsk region. The oil reserves of this tank are classified as difficult to recover (RHR). Research and search for new approaches to the development of the TRiZ facilities of the Preobrazhensky carbonate horizon in this field is today the most important task. The main results of the testing of the complex of geological and technological measures (GTM) are summarized, including a new effective technology for conducting multi-stage hydraulic fracturing, which is planned for use in the further full-scale development of the oil reservoir.

Published: December 2023

Natural gas is a mineral that is the most environmentally friendly energy fossil raw material. In recent decades, proven natural gas reserves have equaled oil reserves in terms of their indicators and, moreover, continue to grow actively. In this regard, the issue of transportation and storage of natural gas becomes relevant. One actively developing area has become the industry of natural gas liquefaction, transportation and distribution.The paper discusses the issues of shipment of liquefied natural gas (LNG) to gas tankers during its large-tonnage production. The authors propose the use of remote filling systems (VSN) for LNG in a similar way to similar devices for filling oil into tankers. However, the main feature of the VSN LNG is the cryogenic pipeline from the onshore facilities to the VSN. In this regard, it is necessary to make a simplified mathematical model of a cryogenic pipeline taking into account heat exchange with the environment and heat release during energy dissipation due to viscous friction forces.In the course of numerical simulation, the dependence of the maximum pumping distance was obtained for a given difference between the temperature of LNG on shore facilities and the maximum required temperature of LNG loading into a gas carrier. The influence of each component of the heat flow equation — heat exchange with the environment and LNG heating due to viscous friction forces was also evaluated.As an example, a section with a length of 10 km was selected and a simulation of the temperature distribution, as well as the required pressure on shore structures necessary to ensure a given loading speed of the gas carrier and the temperature of the supplied LNG was carried out.
PRACTICAL APPLICABILITY OF TECHNICAL REQUIREMENTS FOR CASING PIPES USED IN THE PRESENCE OF HYDROGEN SULFIDE IN THE FORMATION FLUID

Published: December 2023

The optimal ratio of the level of manufacturability of the applied solutions and their cost is one of the key tasks in planning and designing well construction. According to [1] as well as the Casing Design Instructions, in the presence of hydrogen sulfide in the formation fluid, depending on the amount of its content and partial pressure, the well design must provide for casing pipes in a hydrogen sulfide-resistant design. However, the construction of wells in the Volga-Ural region, where most of the fields with H2S content are carried out for about 100 years, and at the same time there were no serious incidents or accidents associated with the destruction of casing pipes from the impact of the mechanism of sulfide-corrosion cracking under stress. In addition, based on the results of analysis of the results of well logging to determine the technical condition of the production strings, it was established that there is no relationship between the cases of revealed casing leaks in the wells and the level of hydrogen sulfide content. In this regard, it became necessary to update the requirements for calculating the design of wells in the presence of a small amount of hydrogen sulfide in the formation fluid. In this case, when calculating casing strings, the level of stress in casing strings arising from tensile loads and overpressures is limited due to the introduction of a factor for reducing the bearing capacity. In other words, this factor corresponds to the ratio of threshold (test) stresses during tests of samples for sulfide-corrosion cracking under stress to the value of the standard minimum yield strength of steel of the corresponding strength group. Based on this, an analysis of the production loads on the casing strings in the wells of the Volga-Ural region was carried out, and the potential for reducing the threshold stress was identified during laboratory tests of samples from casing strings for sulfide-corrosion cracking under stress. Based on the results of analysis of the results of laboratory tests of samples for sulfide cracking under stress in a model medium, it was determined by operating conditions that for seamless casing pipes of strength groups N80Q and R95, the threshold stress can be set to 60% of the minimum yield strength. This article is a follow-up to the publication of the casing specification.

The purpose of the study is to assess the consequences of the impact of the petrochemical industry on the condition of water bodies; studying the level of anthropogenic eutrophication and toxicity of a water body. The article presents the results of using the developed method for determining the eutrophication coefficient for surface rivers, which was carried out on water bodies experiencing the maximum impact of anthropogenic and technogenic factors.The development of research in this area will create the basis for the development of a model for predicting the processes of eutrophication and toxication of water bodies, which is important not only for the industrial hub of the city of Sterlitamak, but also for many regions with a high technogenic load.In this work, the Sterlya River was chosen as the object of study, as a water body located in the zone of influence of chemical and petrochemical enterprises. The laboratory experiment was carried out in accordance with the approved methodology for determining the toxicity of various water bodies and solutions of chemical substances PND F T 14.1: 2: 4.19-20131. During the experiment, indicators such as germination, average length and average dry weight of watercress seedlings were measured.The use of integral methods, which include biotesting methods used to diagnose the state of environmental components in areas with high anthropogenic load, makes it possible to obtain a comprehensive assessment of the object being studied, taking into account many factors, such as natural conditions, environmental parameters, etc.The experimental data obtained confirm both the stimulating and inhibitory effects of the test sample on the analyzed parameters of the test object, which is caused by simultaneous toxic effects and eutrophication processes.It is shown that the proposed method can be used to study the integral toxicity of not only surface and groundwater, but also wastewater, and also to record the dynamics of toxicity in space and time.
CALCULATION OF THE BENDING ANGLE OF THE DRILLING LOCK USING THE FINITE ELEMENT METHOD
Authors: Durymanov N.V. , Garanin P.A.
Published: December 2023

From a long-term analysis of drill string accidents, it was found that the main factor of failures and emergencies is associated with insufficient stability of connecting elements under cyclic loads. This finding highlights the critical importance of the strength and reliability of the joints during the drilling process.The drilling process, which involves constant exposure to cyclic loads, has a significant impact on the structure of the drill pipe and the connections between them. Cyclic loads accompanied by variable loads and moments can cause critical defects in drill string materials and components.A finite element method (FEM) study was conducted to gain a deeper understanding of the tightness of the drill pipe joint. This method is based on a detailed breakdown of the object into finite elements, each of which is a specific portion of the object with well-defined boundary conditions. After splitting and setting boundary conditions, FEA allows you to calculate the distribution of stresses and strains within an object, providing extensive information about its stress state, including data on strains and directions of main stresses.An accurate model of the lock compound was created and subjected to experiments using the finite element method (FEM). This approach allows you to examine in detail the behavior of connecting elements under cyclic load conditions and investigate their stability in various operating scenarios. During the experiments, the bending angle of the pipe was calculated taking into account the target durability. This parameter is very important, since the durability of the drill pipe directly affects their operability and safety under drilling conditions. The obtained results can be used to reduce the risks of accidents during drilling, optimize the design of drill pipes and improve safety in the oil and gas industry.

Качественный перевод жестового языка является одним из решающих факторов, обеспечивающих включение людей с нарушением слуха в социальную среду и доступ к информации. Перевод жестового языка для людей с нарушениями слуха является важнейшим показателем социального благополучия. Обеспечение качества перевода жестового языка явление относительно новое в мировой практике, в России мы только приступаем к осмыслению этого вопроса, формированию критериев качества и механизмов его гарантии. В статье ставится вопрос о том, какие проблемные зоны актуализируются в обеспечении качества перевода русского жестового языка. Для решения этой задачи проведены 16 полуструктурированных интервью с экспертами, на материалах которых выполнен тематический анализ и систематизация проблем обеспечения качества перевода. Ключевыми проблемами обеспечения качества перевода являются: подготовка кадров, статуса языка, «смешение ролей» и «разделение полномочий организаций». Все четыре проблемы уходят корнями в исторически более ранние этапы развития перевода жестового языка в России. На фоне острой нехватки переводчиков, к переводу допускают максимальное число знающих жестовый язык, без особых требований к квалификации и подготовке. Немногие вузы готовят переводчиков, есть сложности с организацией обучения жестовому языку. Имидж профессии препятствует успешному отбору студентов, часть обучавшихся не остается в профессии. Сохраняются старые традиции «сурдоперевода», предполагающие выполнение переводчиком дополнительного функционала социального работника. Спорным остается вопрос о разделении полномочий организаций, представляющих социальный заказ перевода для человека с нарушением слуха, организаций, предоставляющих перевод и организаций, контролирующих качество. В заключении даются краткие пояснения по возможным путям решения накопленных противоречий, что позволит обеспечить качество перевода жестового языка.

Смертность трудоспособного населения России в начале XXI века: есть ли повод для оптимизма?
Authors: Щур Алексей Евгеньевич , Соколова Вера Васильевна , Тимонин Сергей Андреевич
Published: December 2023

Смертность трудоспособного населения, начиная как минимум с 1960-х годов, определяла тенденции изменения ожидаемой продолжительности жизни в России, чем заслуженно привлекала внимание демографов и иных специалистов в области изучения здоровья населения. «Молчаливая» антиалкогольная кампания 2005 г. и общий подъем уровня жизни населения привели к значительному сокращению смертности в трудоспособном возрасте в 2005-2019 гг., обусловив быстрый, хотя в некоторое степени и восстановительный, рост ожидаемой продолжительности жизни. Насколько устойчив окажется прогресс перед лицом новых вызовов? Сохраняются ли резервы для улучшения здоровья россиян в трудоспособных возрастах? В попытке приблизиться к ответам на эти вопросы мы рассматриваем главные, на наш взгляд, изменения в уровне и структуре смертности по причинам смерти россиян в возрасте от 15 до 60 лет.

Исследование охватывает период с 2000 по 2021 г. и строится на данных официальной российской статистики; в том числе использована деперсонифицрованная база умерших, что позволило построить сопоставимые во времени ряды для некоторых причин смерти, что не всегда возможно в силу изменений в краткой номенклатуре причин смерти Росстата. Мы также используем данные Human Mortality Database в случае проведения сравнений со странами с наиболее низкими показателями смертности в трудоспособных возрастах.

В XXI веке наиболее значительный прогресс в России был достигнут в борьбе с внешними причинами (убийства, самоубийства, несчастные случаи); в структуре смертности их постепенно стали вытеснять заболевания преимущественно экзогенной природы (в первую очередь, болезни печени и кардиомиопатия). Особенно ярко это проявилось среди женского населения. Связь динамики смертности трудоспособного населения от всех причин и от «алкогольных», изначально очень сильная, ко второй половине 2010-х годов заметно ослабевает. Наконец, пандемия COVID-19 привела к существенным потерям населения в трудоспособном возрасте вследствие как смертности от самой коронавирусной инфекции, так и избыточного числа умерших от таких причин смерти, как отравления наркотиками и кардиомиопатия.

Несмотря на существенное сокращение в 2005-19 годах, смертность трудоспособного населения в России остается на весьма высоком уровне по мировым стандартам, сохраняя существенные резервы для ее дальнейшего снижения и, соответственно, увеличения продолжительности жизни. Пандемия COVID-19 и, вероятно, последующие события ставят новые вызовы на пути сохранения здоровья россиян в молодых возрастах.
Трудовая миграция в Россию (на примере московского региона): уехать нельзя остаться
Authors: Флоринская Юлия Фридриховна
Published: December 2023

После окончания пандемии COVID-19 и снятия въездных ограничений ожидался рост трудовой миграции в Россию с постепенным возвратом к ее допандемийным объемам. Однако начавшийся в феврале 2022 г. вооруженный конфликт с Украиной, последовавшее введение санкций, падение рубля, турбулентность на рынке труда приостановили начавшийся процесс роста. В то же время не произошло и массового оттока трудовых мигрантов из страны, в том числе потому, что мигранты из стран Средней Азии, ставшие к этому моменту основными поставщиками рабочей силы, пока, по-видимому, не нашли серьезной альтернативы российскому рынку труда.

Трудовые мигранты продолжают работать в России и в 2023 г., однако скудная публикуемая миграционная статистика не позволяет делать прогнозов о развитии ситуации. Для получения дополнительной информации о нынешнем положении мигрантов на российском рынке труда и их ближайших планах на работу в России, ИНСАП РАНХиГС провел два опроса трудовых мигрантов в московском регионе, где работают более 40% иностранных граждан, в марте 2022 г. и марте 2023 г. Большинство опрошенных трудовых мигрантов на тот момент довольно позитивно оценивает свое текущее положение на рынке труда в России и не поменяло своих планов в связи с происходящими событиями. С другой стороны, в ответах на многие вопросы проявляется наличие заметной категории тех, кто не может определенно оценить перспективы своей работы в России в текущей ситуации. Также в 2023 г. определенно снизилась доля желающих стать постоянными жителями России и получить здесь долгосрочные статусы, что подтверждается данными статистики.
Preliminary Validation of the Korean Version of the Alexian Brothers Urge to Self-Injure Scale (ABUSI-K)
Authors: Kim Min-kyeong , Hyun Myoung-Ho , Lee Seo Jeong
Published: December 2023

Background: This study aimed to validate the Korean version of the Alexian-Brothers Urge to Self-injure Scale (ABUSI) for measuring non-suicidal self-injury urges.Methods: Analysis was conducted on a sample of 389 adult men and women who had inflicted self-harm without suicidal intent within three years. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was conducted to confirm the single factor of the scale, and convergent validity was assessed to establish the relationship between ABUSI-K and Negative Urgency (UPPS-P), Self-Criticism/Attacking and Reassurance (FSCRS), and Self-Injurious Thoughts and Behaviors Interview (SITBI).Results: The Korean version of the Alexian-Brothers Urge to Self-Injure Scale (ABUSI-K) showed high internal consistency and, like the original scale, was confirmed to be a single-factor scale measuring the urge to self-injure. Convergent validity with negative urgency, self-criticism/self-attacking and self-reassuring, the NSSI module of self-injurious thoughts and behaviors, and depression and anxiety were also significant, indicating that ABUSI-K’s psychometric benefits are confirmed.Conclusions: The results of this study will provide a multifaceted understanding of self-injury without suicidal intent and the urges that occur before self-injury. They are expected to be useful in clinical interventions for individuals who have engaged in non-suicidal self-injuries.
KHOYA: Jewish Morocco Sound Archive: Sounds, Voices, Memories, and Cognitive Rupture
Authors: Elbaz Vanessa Paloma
Published: December 2023

KHOYA: Jewish Morocco Sound Archive is a pioneering project to repatriate, digitize, record, and classify the remaining sonic memory of Morocco's dwindling Jewish community. This article probes into the necessary sociological cognitive rupture that either allows or disallows the formation of archival repositories of minority memory. Stemming from interventions since the eighteenth century, Morocco's Jewish archives have mainly been kept in the diaspora by Jewish communities and higher education institutions. Contextualizing them within the long durée of Jewish presence in Morocco, this article develops the challenges posed by efforts toward establishing centralized digital archival repositories of the Jewish minority within Morocco itself. This case study proposes a shift into crowdsourced archiving, thus allowing for the alternate grassroots history of Morocco to be maintained and told by intersectional minority actors themselves, while simultaneously engaging with the sonic role, gender, and memory of nonhegemonic and grassroots members of this minority community until today with the formation of an other-archives.
Beyond the Frame: Toward a Collection-Level Redescription of the Colbert Held Archive
Authors: Zohar Ryan
Published: December 2023

This article argues for the collection-level redescription of the Middle East Institute's Colbert Held Archive, a collection consisting of more than 18,000 color Kodachrome slides of photographs taken by Held throughout his time in the region as a diplomat and geographic field researcher. After discussing the importance of the collection and its possible uses for researchers in the field, this article details how any description of the archives should contextualize the American presence in the Arabian Peninsula during the photographer's time in the region. Arguing that the archives places a dual emphasis on geography and ethnography (the concerted combination of which might be called geo-ethnography), the author argues that the archives would be best served by a collection-level, rather than an item-level, redescription. The article draws from academic literature on reparative description, the More Product, Less Process (MPLP) approach, and Total Cost of Stewardship to suggest that this path forward is the most feasible and meaningful step that can be taken by a small special library to contextualize Held's work and his photographs.
The Counter-Archive: Eluding the Erasures of Iraq's Successive Wars
Authors: Alsaden Amin
Published: December 2023

Institutional archives in Southwest Asia (or the “Middle East”) typically reflect the crises that have plagued the region since the advent of modernity. Documentation practices were scarce to begin with, and, if state-sponsored archives were ever established after independence, they usually remained inaccessible. This article ponders the fate of scholarship when the historical record is subjected to another degree of erasure, namely through the systematic destruction wrought by conflicts, as has been the case in Iraq over the past few decades. Using the challenge of accounting for the art-architectural movement that emerged in post–World War II Baghdad as a case study, this obliteration may provide an opportunity for redefining the role that scholars can play in writing histories of modernism in the region. Rather than dwelling on the incompleteness or loss of traditional archives, this article questions and decenters dominant archival practices, especially in places that have experienced, and continue to endure, organized violence. It adopts the notion of the “counter-archive” and demonstrates how alternative sources such as oral accounts, fieldwork, press coverage, memoirs, and private collections can shift the course of research and yield equally valuable alternative histories. Careful interpretation of these nonconventional and typically discredited sources, aided by novel digital representation methods, can not only produce more situated chronicles, defined by the agency of local protagonists, but can also demonstrate that crossing disciplinary boundaries can create richer, layered, and unexpected narratives.

Published: December 2023

Background: Dyspepsia is an upper gastrointestinal disorder affecting 20-45% of the global population. It is characterized by frequent discomfort, burning in the epigastrium and postprandial distress severe enough to hamper routine activities. The aim of this study was to evaluate dyspepsia in young (<40 years) and old patients (>40 years) using ultrasound of abdomen and esophagogastroduodenoscopy as investigative modalities. Methods: The present study was single centre hospital based observational study. 145 patients with dyspepsia were grouped into two categories on the basis of age into those less than and above 40 years of age. All the patients were evaluated using ultrasound of abdomen and esophagogastroduodenoscopy. Results: Epigastric pain was the most common symptom in both groups. It was experienced by 71.23% of the patients less than 40 years and 69.44% of the group above 40 years. Ultrasound examination was normal in majority of patients studied; however more ultrasound abnormalities were detected in the older group of patients. Fatty liver disease was diagnosed in 19.26% younger patients and 48.6% older patients. Cholecystitis and gall bladder polyps were detected only in older patients. Esophagogastroduodenoscopy revealed significant number of abnormalities in both groups. Pangastritis in 21.91% young patients and antral gastritis in 20.80% older patients were the commonest findings in the respective groups. Conclusion: The study concluded that older patients had more frequent organic dyspepsia while younger patients had functional dyspepsia more commonly as evaluated by both esophagogastroduodenoscopy as well as ultrasound examination.

Introduction: Splenectomy is one of the most commonly performed surgical procedures worldwide. The splenic hilum is closely related to adjacent organs like the tail of the pancreas, stomach, splenic flexure of colon, and left kidney. One of the morbid complications of splenectomy is injury to the tail of pancreas. The objective of this study was to assess the anatomical details of the pancreatic tail with respect to the splenic hilum by assessing patient’s abdominal computed tomography (CT) imaging. Methods: A total of 150 patients’ abdominal CT imaging was taken for evaluation in this study. The distance between the pancreatic tail and the splenic hilum was measured. The level of location of the pancreatic tail in relation to the splenic hilum was also noted for each patient. Results: The pancreatic tail was inferior to the level of the splenic hilum in 59.3 percent (n =89) of the patients, superior to the level of the splenic hilum in 2.0 percent (n =3) of the patients, and at the level of the hilum in 38.7 percent (n = 58) of the patients. The mean distance from the pancreatic tail to the splenic hilum was 13.1 ± 5.2 mm. Conclusion: Abdominal CT imaging will provide a road map regarding the location of the pancreatic tail and the distance between the pancreatic tail and the splenic hilum. With the preoperative CT imaging details and efficient surgical dissection as close as possible to the splenic hilum, the potential injury to the pancreatic tail can be prevented.

Ideas about Remorse among Women Serving Sentences in a Correctional Institution
Authors: Tsukanova V.S. , Safuanov F.S.
Published: December 2023

In order to identify the specifics of women’s perceptions of remorse in correctional institutions, a psychosemantic study was conducted using the method of repertoire evaluation grid. The main group consisted of 20 women serving their sentence in the penal colony of the Federal Penitentiary Service of Russia and the control group consisted of 22 women without criminal records. The elements and constructs of the evaluation grid constituted the associations (nouns and adjectives) of the surveyed persons with the concept of "remorse". According to the results of the factor analysis, two main components each were identified in both groups, which were interpreted as “Emotional attitude” and “Sincerity of experience”. The comparative analysis of semantic spaces of the main and control groups, constructed by the results of factor and cluster analyses, shows that convicted women have a significantly reduced concept of remorse: it reflects only the cognitive aspect - awareness of guilt, and does not contain the emotional and meaningful attitude to the offense in the form of regret and experience formed as a result of awareness.
WINTER WHEAT MUTATION VARIABILITY UNDER LOW-DAMAGE ABILITY MUTAGEN ACTION
Authors: HORSHCHAR Vladislav , NAZARENKO Mykola
Published: December 2023

The purpose of our study was to show the possibilities of a chemical supermutagen in the regular induction of certain types of mutations. Winter wheat dry seeds of eight varieties were acted with water (control) and DAB (1.4-bisdiazoacetylbutane) action in concentrations of 0.1%, 0.1%, 0.3%. Studies have shown that the use of this mutagen is expedient from the point of view of obtaining valuable forms of low-growing, earlyripening, late-ripening, high-yielding lines, forms with high productive tillering. The mutagen by its nature has a rather low affinity, at least for this group of genotypes, however, this factor still affects the frequency of some types of mutations. Even extreme concentrations of this mutagenic agent did not lead to a significant decrease in the number of mutations; however, they reached a maximum in the spectrum of possible changes. Further studies are needed on changes in photosynthetic activity and associated persistence.

Aphids are important pests in fields and orchards. The use of chemical insecticides as the main control method resulted in many ecological and health problems. Thus, the development of alternative methods, such as botanical bio-pesticides becomes indispensable in recent years. In this context, we studied the insecticidal and repellent effects of different concentrations of essential oils (EOs) and aqueous extracts from Salvia microphylla (Lamiaceae) against Aphis craccivora aphids, under laboratory conditions. The results showed that higher concentrations of extracts (10000 ppm for EOs and 10% for aqueous solutions) proved significant aphicidal activity, where mortality rates of 100% and 74% were noticed, respectively. Furthermore, aqueous extract at 10% concentration recorded the highest repellent effect (repellency rate = 71.8%). Therefore, the use of extracts from S. microphylla may constitute an important tool in integrated pest management.

The Romanian Senate has adopted in May 2023 a legislative proposal that obliges landowners to remove Ambrosia artemisiifolia L. (also known as the common ragweed) throughout the year, forcing local authorities to penalize those who do not eliminate this plant species. In this context, the present study aims to highlight the Romanian people’s perceptions and attitudes on “ambrozia”, given the fact that this invasive plant represents nowadays a real threat to environment and also to public health, its pollen causing allergic rhinitis. In order to analyze the citizen’s knowledge about the common ragweed, between February and June 2023, an online survey was launched. The anonymous questionnaire was filled out by 585 voluntary participants recruited online from all over the country. The mixed views about the importance of A. artemisiifolia are discussed herein. In addition, the Toolkit “STOP AMBROZIA” was created in April 2023 by Let’s Do It Romania - the partner of Faculty of Agriculture within USAMV of Bucharest - and currently this useful resource can be consulted and free downloaded accessing the Association’s website.

Maize inbred lines derived from local populations (Cycle I lines) were tested using cycle II elite inbred lines. In the cross system, hybrids have a wide variability for yield (6601-10571 kg/ha), the highest differences between hybrids are due to the non-additive genetic effects; undesirable traits transmitted by cycle I inbred lines are weak resistance to stalk breaking and fallen plants; for the percentage of unbroken plants, the genetic variability is high, the percentage of unbroken plants for simple hybrids has a range value between 65.02% and 89.70%.There were calculated the correlations coefficients between ”per se” values for the correlation of inbred lines from crossbreeding system and additive genetic effects values calculated in the crossbreeding system ”m x n”. Positive correlations were identified between the values per se and the positive genetic effects for yield, ear weight, ear length, numbers of kernels per ear, TKW, kernel depth. These high positive correlation values indicate the possibility to use phenotypic markers in the process of inbred lines creation.

The accumulation of chicken litter, due to the excessive emission of gaseous air pollutants, causes a significant load on the environment. Therefore, the basis of research was to find out the level of NH3 and H2S emission from chicken litter by the influence of inorganic and biologically active substances. It is established that the lowest level of NH3 release from litter - by 25.5-32.6% and H2S by 19.7-24.4% is observed with the introduction of a complex preparation for deactivation of enzymatic processes in chicken litter. Of the studied natural sorbents, the best results for reducing NH3 and H2S emission from the litter were obtained by the use of vermiculite - by 24.4-28.7% and 12.6-15.9%. The biopreparation Kapeliukhiv Yarok more effectively affects the reduction of the NH3 release from the substrate (24.3-27.7%) and the Scarabei - H2S (16.1-19.2%). The introduction in chicken litter magnesium acetate and superphosphate helps to reduce NH3 emission by 22.2-22.8% and 22.3- 24.3%, while H2S by 16.0-19.2% and 16.3-17.2%.

Objective: In this study, it was aimed to distinguish bacterial/viral tonsillopharyngitis (TP) by scoring the symptom and throat images of pediatric patients with artificial intelligence-based mobile application.

Method: Fifty-one patients who applied to Sakarya University Training and Research Hospital, Department of Pediatrics and Diseases with acute tonsillopharyngitis were included. Samples were taken from patients and mouth/throat pictures were taken so that the tonsils and pharynx were clearly visible. In the microbiology laboratory, identification with culture/MALDI-TOF MS (Biomerieux, France) from the first samples, and nucleic acid isolation from the other for molecular tests were performed. Symptoms such as fatigue, sore throat, muscle pain, cough, sneezing, and runny nose were questioned from each patient on a scale of 1 to 5. By uploading the symptom results and throat pictures to the artificial intelligence application, it was aimed to distinguish bacterial/viral tonsillopharyngitis with the developed scoring system.

Results: Of the 51 samples included in the study, 21 were culture positive and 30 were negative. The artificial intelligence application was defined as 20 out of 21 culture-positive samples, 3 out of 30 culture-negative samples as bacterial tonsillopharyngitis (Sensitivity: 95.2%, specificity: 90%).

Conclusion: This study is one of the first to bring together the artificial intelligence application and microbiology. AI/scoring system may have a role to play in the diagnosis of bacterial vs viral TP, and in doing so may enable more appropriate antibiotic usage targeted to only bacterial TP infections. It is important to distinguish between bacterial and viral tonsillopharyngitis in the COVID-19 pandemic.

Authors: Hartanto Azwar , Wardana Rahmad Wisnu , Garside Anissa Kesy
Published: December 2023

PT XYZ operates as a paint manufacturing company, producing two types of products, namely wall paint and pool paint, based on distinct raw materials. Within the production process, the role of the farfly mixer machine holds significant importance, as it facilitates the crucial mixing and dispersion processes involved in paint manufacturing. Unfortunately, operational usage of the farfly mixer machines often leads to malfunctions, resulting in disruptive downtimes and potential financial losses for the company. Consequently, an enhancement of the machine maintenance planning is imperative, utilizing the risk-based maintenance methodology to ascertain risk estimations associated with machine failures, conduct risk evaluations, and devise appropriate maintenance plans. The assessment of risk estimations yields a significant risk value amounting to IDR 10,459,765 per month. The evaluation results reveal that the calculated risk value surpasses the acceptance criteria, specifically denoting 0.73% compared to the expected threshold of 0.60%. Consequently, based on this risk evaluation outcome, it becomes evident that maintenance planning is warranted, necessitating the formulation of a proposed maintenance plan. The proposed plan focuses on optimising component replacement intervals, primarily targeting components with a reliability value lower than 80%.
