Published: March 2023

Background: Agriculture, being the main source of livelihood in most parts of the country, has some hidden dangers to the farmers which get them injured or ill.
Methods: A community-based cross-sectional study was conducted for 2 months among farmers aged >18 years of age residing in rural Mysuru. A purposive sampling technique was used and the data was collected from 150 farmers through house-to-house interviews using a pre-tested structured questionnaire.
Results: The survey took account of the farmer's opinion on first aid procedures; a vast majority of the practices weren’t supported by any scientific evidence. Ineffective first-aid procedures could worsen the problem. Thus, the farmers should receive sufficient first aid training and education, enabling them to take appropriate action for themselves and their communities in an emergency.
Conclusions: The survey took account of the farmer's opinion on first aid procedures; a vast majority of the practices weren’t supported by any scientific evidence. Ineffective first-aid procedures could worsen the problem.

Published: March 2023

Background: COVID-19 pandemic has been a global serious problem adversely affecting human life. This study aimed at documenting the impact and pattern of WhatsApp use among the school students during these unprecedented times.
Methods: A cross-sectional study was conducted on 434 students belonging to grade IX, X, XI and XII, of 13-19years age group, from randomly selected four English medium schools of Surat city, India. Univariate and bivariate analysis was carried out by Epi-info software.
Results: One out of every six students (16.5%) of Class IX used WhatsApp for >1 hour per day compared to 13.6% of Class XII students (χ2: 23.478, DF=6, p=0.001). The total time spent on WhatsApp per day by 22.8% of girls and 13.5% of boys was >1 hour (χ2: 11.532, DF=2, p=0.003). Almost 22% students of Class IX were checking WhatsApp status every time they hear message tone compared to 15.2% of Class XII students at work/ class (χ2: 19.168, DF=9, p=0.024) and at home/leisure time (χ2: 19.009, DF=9, p=0.025). A quarter (23.04%) of students reported that they would continue the use of WhatsApp even if it becomes a paid application. The most common reason for using WhatsApp among boys was its user-friendly nature while for the girls it was the ease of use.
Conclusions: Girls as compared to boys spend more time on WhatsApp per day and have more number of groups where they are active. Class IX students were more prone for problematic use of WhatsApp as compared to the rest.

Published: March 2023

Background: Vitamin D is vital in children mainly because of its profound effect on growth, development, immune system and importantly bone health. Recent evidence suggests maintaining 25 (OH) D levels above 20 ng/ml for maximizing health benefits. Objectives were to assess the vitamin D status in children in the age group of 5-15 years attending a tertiary care teaching institute of North India and to analyze the factors which can contribute to vitamin D deficiency in these children.
Methods: It was a cross-sectional study. 5-15 years old children attending the outpatient department were included in the study. Children with co morbid conditions that affect vitamin D metabolism and those children on chronic drug treatment and on vitamin D supplementation were excluded from the study.
Results: Average age of study population was 8.93±2.02. In the study 170 (18.47%) children among a total of 920 had a normal vitamin D status while the rest 750 children (81.52%) had insufficient vitamin D status (25 hydroxy vitamin D <30 ng/ml). Among these children 190 (26.38%) had suboptimal vitamin D levels, 300 (40%) were deficient, 143 (19.06%) had severe and 117 (15.6%) had very severe deficiency of vitamin D. The average vitamin D level among the study population was 12.33±11.13 ng/ml. There was significant statistical association between vitamin D deficiency and stunting (p=0.003). No statistically significant association was found between outdoor activity.
Conclusions: Vitamin D insufficiency was documented in 81.52% of 5-15 years old children and there was a significant association between stunting and vitamin D deficiency.

Published: March 2023

Background: Anemia is one of the leading causes of mortality and morbidity in children. The etiology of anemia is multifactorial including nutritional anemia, hemolytic anemia, aplastic anemia, storage disorders, hematological malignancies, anemia secondary to some chronic diseases.
Methods: The study is an observational study. Physical signs of severe anemia were looked in patients attending outpatient department or admitted in hospital. Children with hemoglobin levels <7 g/dl and in the age group 6 months to 6 years were recruited in study. The aim is to look for non-nutritional etiology of severe anemia in children in Kashmir.
Results: Out of 192 children, 97 (50.52%) females and 95 (49.48%) males, with a male, female ratio of around 1:1. A total of 147 (76.56%) children in our study were having nutritional and 45 (23.44%) were having non nutritional causes. Among non-nutritional anemia 30 cases were hemolytic anemia, 11 hypoplastic anemia, 3 leukemia and 1 patient were diagnosed as Osteopetrosis.
Conclusions: Though nutritional deficiency anemias are predominant; it may not always be the case. Hemolytic anemia and leukemias should be ruled out while evaluating a patient of severe anemia and pancytopenia. Bone marrow failure syndrome, storage disorders should be ruled out in patients with skeletal anomalies.

Published: March 2023

A exploração de agregados envolve a extração de recursos naturais não renováveis e, com isso, modifica-se o meio ambiente, causando impactos ambientais. Com o propósito de mitigar esses impactos, diversas pesquisas vêm sendo desenvolvidas objetivando o aprimoramento de tecnologias que substituam os agregados naturais por subprodutos, como aqueles gerados na britagem de rochas para obtenção de brita de construção e do beneficiamento da scheelita. Nesse contexto, a presente pesquisa tem como objetivo o estudo de argamassas de revestimento produzidas com substituição total do agregado natural por uma areia constituída de pó de pedra e subproduto de scheelita. Para isso foram formuladas argamassas no traço de 1:3, em volume, as quais foram analisadas quanto às suas propriedades no estado fresco e endurecidas, incluindo análises de microestrutura. A argamassa produzida a partir da combinação, em partes iguais, do pó de pedra e do subproduto de scheelita, no estado fresco, embora mais densa, obteve melhor consistência e teor de ar incorporado semelhante ao da argamassa de referência. No estado endurecido, a formulação alcançou elevada resistência mecânica, maior densidade de massa e menor absorção de água. Aplicada como revestimento, a formulação obteve resistência de aderência à tração superior aos valores estabelecidos pelas normas brasileiras, o que ratifica a viabilidade da utilização da composição binária proposta como agregado para argamassas.
Fast Shape-Preserving Method for Integrating Polygon into Two-and-Half Dimensional Triangulation
Authors: Stanchev Bozhidar , Paraskevov Hristo
Published: February 2023

This paper presents an approach in integrating polygons into a triangulation. The motivation behind this work is to find a way to overcome the lack of appropriate shape-preserving methods for modifying 2.5D triangle meshes.
Widely used approaches for constructing Constrained Delone Triangulation (CDT) work in two steps: first constructing pure Delone triangulation, and next inserting the line segments one-by-one into it [1], [2], [3].
The presented method implements an effective mesh data structure and a walking-on-mesh approach allowing for fast polygon traversal looking for the intersected edges of the 2.5D mesh. Instead of reconnecting vertices or re-triangulating the affected mesh area, we introduce new mesh vertices and subdivide the mesh in order to integrate the polygon. The technique also examines and enhances the aspect ratios of the 2.5D triangles that are present in (and near) the partitioned area while maintaining the shape.

The disparities in access to public assistances between rural and urban areas are analyzed in this study, corresponding to the intensity in which the constructs are related to expected quality, perceived quality and perceived value as influential factors in citizen satisfaction and loyalty. In Guayaquil, a survey is carried out at the household level, 428 valid questionnaires are obtained in the rural area of Tenguel and 521 Valid questionnaires in the urban area of Tarqui, applyingto the American Customer Satisfaction Index (ACSI). The research used a Structural Equation model (SEM) to evaluate the hypotheses raised, if they observe significant differences in citizen perception between inhabitants of urban and rural areas about the quality of community services, this as a determining cause in the level of citizen satisfaction and loyalty to choose their municipal authorities. The multigroup analysis allowed to identify inequalities in the observation of the quality of municipal or local communityassistances between rural and urban areas; the findings are considered to local public administrators for the design of public policy aimed at improving levels of citizen satisfaction and loyalty.Sentiment analysis is a way to automatically understand and process text data to figure out how someone feels about an opinion sentence. If there are too many reviews, it will take a lot of time and they will start to be biased. Sentiment classification tries to solve this problem by putting user reviews into groups based on whether they are positive, negative, or neutral. The dataset comes from Drone Emprit Academic. It is made up of tweets with the words "online learning method" in them, with as many as 4887 data crawled from them. Information Gain and adaboost on the C4.5 (FS+C4.5) method are used in the feature selection method. We use feature options to get rid of bias and improve accuracy. The results of the experiments will be compared to other algorithms like C4.5 and random forest. Based on the results, the accuracy of the two standard decision tree models (C4.5 and random forest) went up from 48.21% and 50.35% to 94.47 %. The value of how accurate it was went up by 44 percent. The FS+C4.5 model, on the other hand, has an RMSE of 0.204 and a correlation of 0.944. So, adding the feature selection technique to the sentiment analysis of bold learning education can make the C4.5 algorithm even more accurate.

Authors: Suin Guaraca Luis Heriberto , Saetama Flores Tatiana Rosibel
Published: February 2023

RESUMEN

Introducción: La seguridad social se fundamenta en la entrega oportuna de servicios de salud, evitando la falta de protección y el empobrecimiento de las familias que se asocia de manera directa con excesivos gastos de bolsillo.

Objetivo: Estimar el efecto que tiene la afiliación al Seguro Social General (SSG) en el Gasto de Bolsillo en Salud (GBS) en los hogares ecuatorianos para el año 2014.

Metodología: El efecto se estimó mediante el análisis estadístico Propensity Score Matching y utilizando el programa Stata, sobre una muestra de 22,364 observaciones, de las cuales 7,509 son tratadas – hogares afiliados al SSG – y 14,855 son de control – hogares sin ningún tipo de afiliación –, datos tomados de la encuesta de Condiciones de Vida realizada por el INEC para el año 2014. Como variable de resultado se utilizó a los gastos de bolsillo y como variable de tratamiento a los hogares en los que al menos, el jefe del hogar este afiliado al Seguro Social General.

Resultados: Se encontró un efecto positivo entre la condición de afiliados al SSG y el GBS de los hogares, el afiliado tiene una propensión a realizar mayores gastos privados en salud que el no afiliado, incrementándose aún más si el jefe del hogar es de sexo masculino. Para los dos sexos, la similitud es únicamente en la covariable ingresos, sin embargo, cuando el jefe de hogar es de sexo femenino, las covariables significativas se incrementan.

Conclusiones: Los afiliados al SSG muestran un incremento en los GBS lo que significaría una falta de protección financiera a pesar de los aportes mensuales realizados a la seguridad social.

Earthquake and the Lung
Authors: GÜLEÇ BALBAY Ege
Published: March 2023

Natural disasters cause extensive damage to nature and impact on large numbers of people throughout the world. Recently, earthquakes have caused a large number of death, injured, missing, and displaced people. More than a million earthquakes occur worldwide every year, which equates to roughly two earthquakes per minute. Lung problems in earthquakes are one of the main causes of morbidity and mortality. Many pulmonary complications that occur after earthquakes are a direct result of the disaster itself. Pulmonary complications such as inhalation of dust and particulates from collapsed buildings in earthquakes, aspiration of water and pathogens due to tsunami after earthquakes, pulmonary thromboembolism, psychological effects caused by respiratory symptoms, infectious respiratory diseases and chest traumas such as pneumothorax, rib fracture, hemothorax, hemopneumothorax, diaphragmatic tear can develop after earthquakes. People in the earthquake area, search and rescue teams, and those involved in demolition and debris removal activities are at risk for asbestos exposure. The most effective solution against the lung effects of earthquakes is to take preventive and protective measures. It is very important for disaster preparedness and response teams to be aware of these problems. Respiratory problems that may arise in earthquakes were discussed in this review.

Изложена краткая информация о всплытии двух из четырех ниток Северного потока-2 на участке подводного перехода через Байдарацкую губу на Ямале. Рассмотрены следующие три постановки задачи о напряженно-деформированном состоянии рассчитываемого подводного участка газопровода: с учетом воздействия внутреннего давления и температурных напряжений на изгиб трубопровода, вызывающего дополнительный изгиб газопровода; с пренебрежением воздействия внутреннего давления и температурных напряжений на изгиб трубопровода; с компенсаторами, установленными в начале и конце рассчитываемого участка. Представленное решение для первой постановки задачи зависит от обычных тригонометрических функций, для второй постановки задачи – от многочленов, а в третьей постановке – от гиперболических и тригонометрических функций. Для этих трех постановок задач рассчитаны основные характеристики напряженно-деформированного состояния газопровода, построены эпюры его прогиба и изгибных напряжений, в таблицах приведены экстремальные величины этих характеристик для различных значений параметров эксплуатации газопровода для разной длины размытой оголенной части, и с учетом изменения состояния грунта на прилегающих подземных частях. Установлена эффективная работа компенсаторов, предназначенных для предотвращения всплытия подводных участков морского газопровода и сохранения их в проектном положении.

Использование перекрестной схемы резания для снижения пылевидных и необогатимых фракции при механизированной добыче калийной руды // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2023. – Т. 334. – № 2. – С. 60-69.

Актуальность. Добыча калийной руды с использованием проходческо-очистных комбайнов характеризуется высокой степенью пылевыделения в призабойной зоне. Основными источниками пылевыделения являются процессы разрушения массива, погрузки отбитой горной массы и перегрузки руды. Длительное нахождение горнорабочих в зоне с превышением предельно допустимых концентраций по калийной пыли в атмосфере выработки негативно сказывается на их здоровье. С точки зрения экономических потерь переизмельчение руды также имеет негативный эффект. Частицы полезного компонента размером менее 250 мкм не поддаются обогащению и уходят в отвал. Зачастую количество необогатимой руды при поступлении на обогатительную фабрику достигает 18 % от общей массы. В связи с этим актуальной является разработка мер по снижению концентрации пыли, выделяемой при функционировании проходческо-очистного комбайна, в рабочей зоне машиниста и снижению количества необогатимой фракции в добываемой руде. Цель данного исследования заключается в разработке и внедрении мероприятий по изменению исполнительных органов проходческо-очистных комбайнов, которые будут способствовать снижению пылевыделения в призабойной рабочей зоне калийных рудников. Объектом исследования является исполнительный орган проходческо-очистного комбайна с режущим инструментом. Результаты. Предлагаются технические решения по совершенствованию механической конструкции исполнительных органов проходческо-очистных комбайнов калийных рудников. Перспективный плоский планетарно-дисковый исполнительный орган позволит реализовать на поверхности калийного массива перекрестную схему резания и разрушать забой последовательными элементарными сколами устойчивой формы, что обуславливает снижение удельных энергозатрат на процесс отделения калийной руды от массива и уменьшение количества пылевидных классов в продуктах отбойки.

Актуальность исследований по разработке и численной реализации математических моделей тепломассопереноса в замораживаемых грунтах и породах в условиях строительства шахтных стволов обусловлена рядом технологических факторов и особенностей организации данного процесса. Корректный расчет искусственного замораживания пород для конкретных практических случаев оказывается невозможен без учета таких факторов, как переменный режим работы замораживающих колонок, наличие двух контуров замораживания, различная длина питающих труб замораживающих колонок, теплообмен с пространством шахтного ствола переменной глубины, образование каверн в объеме замороженных пород вследствие вывалов породы, тепловыделение от твердеющего цементного раствора, фильтрация поровых вод. Представляет интерес описание и анализ особенностей реализации данных факторов на примере модели тепломассопереноса, исполненной в специализированной программе FrozenWall, предназначенной для теплотехнического расчета замораживания пород и разработанной при участии авторов статьи. Цель работы состоит в описании и анализе внесенных улучшений в модель и алгоритмы программного обеспечения FrozenWall в ходе проведения работ по контролю состояния ледопородного ограждения на строящихся вертикальных стволах калийных рудников. Объектом исследования являются влажные горные породы, подверженные тепловому влиянию системы искусственного замораживания при строительстве вертикальных шахтных стволов. Методы включали экспериментальное измерение температуры в контрольно-термических скважинах, обработку полученных данных, математическое моделирование процесса искусственного замораживания пород, параметризацию модели теплопереноса в породах по данным натурных наблюдений посредством решения обратной задачи Стефана. Результаты. В ходе проведенной модернизации в программе FrozenWall были добавлены алгоритмы, учитывающие такие технологические факторы, как нестабильная работа замораживающих колонок, наличие двух контуров замораживания, различная длина питающих труб замораживающих колонок, теплообмен с пространством шахтного ствола в случае его затопления, образование каверн в объеме замороженных пород вследствие вывалов породы, тепловыделение от твердеющего цементного раствора в строящемся стволе, плоскопараллельная фильтрация поровых вод. Посредством программного учета этих факторов становится возможным разрабатывать новые технические мероприятия, нацеленные на повышение энергоэффективности и безопасности углубки шахтных стволов в обводненных горных породах, снижение вероятности возможных аварийных ситуаций.

Актуальность. Добыча природного газа и попутных нефтяных газов сопровождается необходимой подготовкой газа для поставки потребителю для коммерческого использования. В частности, на месторождениях газа и нефти применяются отделение всех побочных гомологов метана, влаги и других неуглеводородных соединений, входящих в состав попутных нефтяных газов, ухудшающих условия эксплуатации оборудования и понижающих качество исходного сырья. При постоянно растущей степени обводненности газовых и нефтяных месторождений необходимо поступательное развитие технологических методов подготовки газа, в том числе одного из наиболее распространенных в РФ – абсорбционного метода осушки природного и попутных нефтяных газов от примесей воды. Цель: обосновать применение диэтиленгликоля как наиболее эффективного абсорбента в условиях Крайнего Севера при подготовке природного газа. Объект: установка комплексной подготовки природного газа. Метод. Расчет модели установки комплексной подготовки газа произведен в программном комплексе UniSim Design R470. Результаты. Исследовано влияние основных технологических параметров: температуры, давления процесса абсорбционной осушки природного газа на абсорбенте диэтиленгликоль на установке подготовки газа для удаления примесей воды. Определены оптимальные условия по давлению и температуре для эффективного удаления влаги из природного газа методом абсорбции воды диэтиленгликолем при высоком давлении входного сырья. Показано, что применение абсорбента диэтиленгликоля наиболее эффективно в условиях Крайнего Севера. При использовании диэтиленгликоля в качестве абсорбента для осушки природного газа от воды при низких температурах значительно уменьшаются энергозатраты на компримирование газа, его охлаждение перед абсорбером и расход осушителя по сравнению с другими абсорбентами. Определены наиболее эффективные технологические параметры работы абсорбционной установки по осушке природного газа при концентрации диэтиленгликоля 98 % мас. и расходе сырого природного газа 385 тыс. м³/ч. Диэтиленгликоль уже при температуре контакта 19 °С осушает газ до регламентируемых показателей температуры точки росы минус 20 °С и давлении в установке подготовки газа не менее 4 МПа и выше. Напротив, превышение температуры контакта газ–диэтиленгликоль выше 20 °С и снижение давления менее 4 МПа приводит к значительному повышению энергозатрат, уносу абсорбента диэтиленгликоля и ухудшению экономических показателей процесса осушки природного газа от примесей воды.

Question
In sea turtles presenting for cold-stunning (sustained hypothermia), what blood analytes routinely evaluated at intake provide the most prognostic value?
Clinical bottom line
Category of research question
Prognosis.
The number and type of study designs reviewed
Ten studies were included in this evaluation including the following study designs: eight retrospective case series, one cross-sectional, and one retrospective cohort.
Strength of evidence
Weak.
Outcomes reported
The most consistent finding across all included studies in cold-stunned sea turtles was acidosis (suspected both respiratory or metabolic components) characterised by reduced blood pH, elevated partial pressure of carbon dioxide (pCO2), and reduced partial pressure of oxygen (pO2). However, this finding was not necessarily linked with failure of rehabilitation. Rather, sea turtles presenting for cold-stunning that did not survive rehabilitative therapy were typically in extreme states of homeostatic derangement involving acidosis, but often in conjunction with additional abnormalities (e.g. anaemia, sepsis, organ failure or dysfunction, pneumonia, etc.).
Conclusion
As might be expected, the evaluated literature did not reveal a single or series of blood analytes that were definitively linked with the success or failure of rehabilitation in sea turtles presenting for cold-stunning. However, they did identify analytes that may provide the most clinical value in this clinical situation including packed cell volume (PCV), estimated white blood cell count (WBC), total and / or ionised calcium, pH, potassium (K), and lactate. Review of the available studies on the topic provides insightful information that can aid clinicians addressing this syndrome to triage and treat affected individuals most effectively. It also elucidated areas of opportunity for further research.
 
How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
