The work is devoted to the development of a measuring method of the thermal characteristics of metals with thin coatings applied by galvanic method on the base metal, for use in thermal equipment of renewable energy sources. Designed and manufactured laboratory equipment for measuring the thermal characteristics of metals with thin coatings and thin coatings applied to the base material. A study was conducted to determine thermal conductivity and heat capacity on the example of a nickel coating applied to a copper base by galvanic means in a magnetic field of low induction. The calculation results showed that the thermal conductivity of the coated base is 326 W/(m×°К) and is lower than the thermal conductivity of the copper base (394 W/(m×°К)). This is due to the fact that nickel has a much lower thermal conductivity than copper. In addition, an additional transition layer is formed at the copper-nickel interface, which can also impair thermal conductivity. The heat capacity of nickel-plated copper was 0.4285 kJ/(.kg·°K) and is greater than the heat capacity of pure copper. In general, a copper base with a protective nickel coating has good thermal characteristics and can be used in heat-conducting equipment. The method proposed in this paper allows to determine the thermal characteristics of metals with thin coatings and coatings applied electrochemically on a heat-conducting base, and to determine the possibility of their use in heat-conducting equipment.
ВПЛИВ ШУНТУВАННЯ СТРУМУ ТА ТЕХНОЛОГІЧНИХ ПАРАМЕТРІВ ТОЧКОВОГО ЗВАРЮВАННЯ НА МІЦНІСТЬ З'ЄДНАНЬ ГАБАРИТНИХ ВИРОБІВ

Досліджено вплив шунтування струму та технологічних параметрів точкового зварювання на міцність з'єднань габаритних виробів. Досліди проводили з використанням машини точкового контактного зварювання типу МТ-1614. В якості основного матеріалу, що з’єднувався, обрали конструкційну вуглецеву сталь марки 08Ю у вигляді пластин різної товщини. Після виконання зварювання виготовляли зразки для випробувань за стандартними методиками на зріз, відрив або скручування. Експериментальна частина роботи включала визначення залежності величини зусилля руйнування та діаметра зварної точки від зварювального струму, відстані між звареними точками та тривалості імпульсу зварювального струму. Визначено, що оптимальний зварювальний струм для забезпечення високої міцності зварних точок становить значення в діапазоні від 7400 і до 8000 А. Перевищення цього значення призводить до зниження міцності, особливо при збільшенні відстані між зварними точками. Тривалість імпульсу зварювального струму також відіграє важливу роль: оптимальний приріст міцності спостерігається при імпульсах тривалістю 0,18…0,22 с. для струмів 7900…8200 А. Також встановлено залежність діаметра зварної точки від відстані між зварними точками та тривалості імпульсу. Суттєве збільшення відстані між зварними точками призводить до зменшення їх діаметра. З іншої сторони, тривалість імпульсу струму в межах 0,22…0,24 с підвищує діаметр точок у середньому до 22 %. За результатами експериментів були розроблені математичні моделі, що кількісно оцінюють вплив досліджуваних параметрів на міцність та діаметр зварної точки. Практичні рекомендації включають оптимізацію параметрів зварювання та впровадження математичних моделей у виробничий процес для прогнозування якості зварних з'єднань. Отримані результати сприятимуть підвищенню якості зварних з'єднань та ефективності виробничих процесів при виготовленні габаритних виробів.

Published: December 2024

Public finance is concerned with the funds that the public sector creates and distributes. Public finances are to some extent similar to the finances of the so-called “third sector” (non-profit organisations), due to the type of activities that are geared towards meeting certain social needs. They are based on the authority of the public sector and are established in a coercive manner; they should be an instrument for pursuing the interest of the general public. They operate according to specific plans, and the size of the public resources and operations carried out through them are much larger than those of private entities. Thus, through public finances, the state significantly influences the socio-economic processes and the efficiency of the use of public resources. Through various instruments and tools of fiscal and monetary policy, the state pursues economic and social objectives. We can divide public finances into state finances, finances of local government units and finances of the social security system.
Prematurity and growth retardation: different causes of fetal coagulation disorders

Published: December 2024

prematurity and fetal growth retardation complicates in general one in five pregnancies. The combination of prematurity with severe growth retardation and hypoxia worsens the prognosis due to increase of periventricular hemorrhage incidence, and later coronary heart disease, hypertension, stroke, miscarriage and fetal growth retardation in own pregnancies in adulthood. The causes of impaired blood coagulation and fibrinolysis in retardated and premature newborns remain poorly understood. The goal of the study - to compare the parameters of blood acid-base and gases balance, coagulation and fibrinolysis in prematurity and growth retardation. Material and methods. Newborns of three clinical groups were examined. 24 full-term newborns with a postnatal diagnosis of I-II growth retardation stage constituted group I. 18 newborns of group II were born prematurely, corresponding to pregnancy term of 28-34 weeks. Control group III consisted of 20 full-term healthy infants. The birth took place without emergency interventions and without perinatal losses. Blood samples of the umbilical cord artery were obtained immediately after it was clamped. The parameters of blood acid-base and gas compositionof mothers and newborns blood and the fetal kinetic characteristics of blood coagulation and fibrinolysis were compared. Results. Newborns of group I had a pH of 7.27±0.012, in group II - 7.33±0.022, in group III - 7.30±0.024, which corresponded to the difference between maternal and fetal values of 0.10; 0.07 and 0.13. The pH difference in growth retarded fetuses is higher than in premature fetuses, closely to that of full-term fetuses, despite the lowest pH. Parameters of pO2 and pCO2 in labor do not have an indicative difference in newborns of all groups. Thromboelastometric parameters of the premature infants blood indicate low density and accelerated clot lysis, but while growth retarded fetuses accelerated formation and incomplete clot lysis. That is because of notable predominance of endothelial origin procoagulant factors in growth retarded fetuses. Indicators of acid-base and gas balance in newborns with growth retardation are shifted towards acidosis, in contrast to anthropometrically similar premature infants, whose indicators are higher than full-term fetuses ones.
Intervenções ginecológicas e o sofrimento psíquico da mulher cis associado à experiência cirúrgica: uma revisão integrativa de literatura
Authors: Santos Rodrigues Kassia 
Published: December 2024

O As intervenções ginecológicas cirúrgicas representam na oferta de cuidado a mulher cis um elemento fundamental para manutenção da saúde, dado que essas são recursos de eminência para afecções no aparelho genital feminino, considerando-se a pelve e mamas, assim, corrobora-se para uma perspectiva que perpetua o objetivismo médico a orbe da dissipação dos sintomas em um órgão adoecido com a desvalorização da pessoa atendida, subordinando o sujeito ao saber médico, afastando-se, em consequência, da possibilidade de humanização e de um tratamento que reconheça as questões da mulher. Destarte, a presente pesquisa objetiva expor, mediante a um método qualitativo, as dimensões psicológicas, sociais, culturais e físicas envolvidas na experiência da intervenção ginecológica cirúrgica, posto que a interferência em órgãos que confere feminilidade sob uma ótica de visibilidade ou não, emerge conflitos inerentes à construção simbólica do corpo feminino, anuente a uma perspectiva biológica que exerce influência direta na percepção social da mulher. Para tal, realizou-se um levantamento bibliográfico integrativo, o qual identificou através da Biblioteca Virtual da Saúde (BVS) 152 produções, no entanto, permaneceram 119 mediante aos critérios utilizados para inclusão e exclusão na presente pesquisa e, destes estudos, elegeu-se 5 produções para a realização desta revisão bibliográfica. Portanto, verificou-se, através do aporte teórico, as repercussões da intervenção cirúrgica ginecológica no exercício da vida cotidiana frente aos papeis sociais atribuídos ao feminino, os quais se orientam a aspectos de uma construção consolidada em sociedade e que intervém diretamente na identidade sua formativa, ademais, identificaram-se as implicações à vida da mulher, no que se refere à sedimentação da sua autoimagem, mesmo que a percepção do útero seja só inferida mediante a gestação ou frente a necessidade de sua remoção, associando-se a experiência de adoecimento e intervenção com sintomas depressivos, relacionamento sexual e conjugal, sintomas psicossomáticos e autoconceito.

Published: December 2024

Background : Postdated pregnancy is a high risk pregnancy in obstetric situation because the perinatal morbidity and mortality exceed that of term pregnancies. According to the definition provided by the WHO and International Federations of Obstetrics and Gynaecology, a prolonged pregnancy is one that exceeds 294 days or 42 weeks from the first day of last menstrual period and postdated pregnancy is a condition which has passed beyond the expected date of delivery.
Objectives:To reduce the maternal and perinatal morbidity and mortality and to reduce the incidence of operative delivery in primigravida and multigravida patients in post dated pregnancy.
Materials and methods :The study was carried out from January to June, 2012 in the department of Obstetrics and Gynaecology, Dhaka National Medical Institute Hospital (DNMIH) Dhaka. Out of 206 women with postdated pregnancy, admitted during the study period in the obstetric ward of DNMIH, 80 women who fulfilled inclusion criteria, constituted the study population.
Results :In the present study out of 80 women with postdated pregnancy, 42(52.5%) were primaegravida and 38(47.5%) were multigravida. All the women of primaegravida group belonged to age group <30 yrs 42(100%) compared to 26(68.4%) multigravida. In this study, significantly more multigravida achieved normal vaginal delivery (19% primaegravida and 47.4% multigravida). Higher number of primaegravida (81%) delivered by LUCS compared to multigravida (47.4%) Postdated pregnancy did not affect significantly on the fetal weight between primaegravida and multigravida group (mean SD 2.93± 0.31 vs. 3.01±0.40 kg). However Apgar score was significantly lower in multigravida group (mean±SD 6.61±1.05) compared to primaegravida group (mean SD 7.19± 1.10). Maternal complications were higher among primaegravida compared to multigravida. In the present study, there was no neonatal or maternal death.

Diseases among young children are the major causes of morbidity and mortality particularly in the developing countries of the world.Children under five years of age are the most vulnerable section of the society and suffer from highest morbidity. The present study makes an attempt to assess the morbidity pattern among the children of under five years in an urban slum and find out its association with various factors. This descriptive cross-sectional study was conducted for a period of 6 months from September 2013 to February 2014 in an urban slum area of moghbazar in Dhaka city. A house to house survey was conducted and a total of 439 children of under five years were enrolled for the study. Out of total 439 children, 244 (55.6%) were females and 95 (44.4%) were males. Among the children 56.5% were suffered from one or more sickness. Overall health morbidities were more in females 59%. Acute respiratory infection (ARI) 215 (49%) was the commonest morbidity found during study period followed by fever 199 (45.3%), diarrhoeal diseases 160 (36.4%), malnutrition 79 (18%) and helminthiasis 75 (17%). Most of the children of under five years suffered from ARI, fever, diarrhoeal diseases and malnutrition were in the age group of 25-36 months. Helminthiasis was more in the age group of 37-48 months and skin problem was more in the age group of 25-36 months. ARI, diarrhoeal diseases, skin problem and infectious diseases were more in male under five years children while, fever, malnutrition and helminthiasis were more in female under five years children. Accident was more in male under five children and the relation was statistically significant. (p=0.03). A statistically significant association was found in diarrhoeal diseases with monthly family income (p= 0.03) and mother’s occupation (p=0.001) and also between skin problem and mother’s education (p=0.022) and occupation (p=0.000). A statistically significant association was found in morbidity pattern of diarrhoeal diseases, fever and helminthiasis with type of house (p=0.017, p=0.009, p=0.000).

Published: December 2024

Introduction: Pregnancies complicated by threatened abortion constitute a risk group requiring careful obstetric and perinatal supervision and follow-up.
Objective: The purpose of this study was to evaluate the risk factors and adverse pregnancy outcomes with threatened abortion.
Methods: The prospective study was conducted in Obstetrics and Gynecology Department in Dhaka National Medical College Hospital from 1st July, 2011 to 31st December, 2013. Pregnant women presenting with per vaginal bleeding admitted before 24 weeks were included in this study group. Diagnosis of threatened abortion was confirmed from history, clinical examination & ultrasonic finding of alive fetus. We followed up all the women from their first appointment until delivery and outcomes were determined.
Results: In this study 69% pregnant woman with threatened abortion were multigravida. Out of 100 pregnant women, 32 cases of pregnancy ended with abortion and rest 68 cases could continue pregnancy. Among the 68 cases, 57.35% neonate were pre-mature, 54.41% low birth weight, 17.65% neonate presented with respiratory distress syndrome and 13.23 % intra uterine growth retardation and 4.41% developed intra uterine death. Ultrasonographic study of pregnant women showed, 19% patients ended with incomplete abortion and 13% missed abortion. Among the 68 cases 13.23% were placenta praevia and 7.35% were plaecental abruption.
Conclusion: Threatened abortion was associated with an increased incidence of adverse pregnancy outcomes and most commonly associated with abortion, pre-maturity, low birth weight, and intra uterine growth retardation and intra uterine death. Pregnancy with threatened abortion who continued had increased risk of low lying placenta, placenta praevia, and placental abruption.

Associations of maternal emotional intelligence and coping strategies with diabetes management in adolescents with type 1 diabetes
Authors: Zaleckytė Dovilė , Žilinskienė Jolanta 
Published: December 2024

Purpose: The study aimed to evaluate the association between maternal emotional intelligence and coping strat[1]egies with diabetes management in adolescents diagnosed with type 1 diabetes.
Design and Methods: A cross-sectional study was conducted with mothers of adolescents (aged 12–17 years) with type 1 diabetes (n = 75). Data collection instruments included the Trait Emotional Intelligence Question[1]naire-Short Form (TEIQue-SF) and the Brief COPE, alongside a structured questionnaire covering diabetes man[1]agement and sociodemographic factors. The primary outcome measure of diabetes management was glycosylated hemoglobin (HbA1c) levels. Data were collected via both paper-based questionnaires and an online survey in 2023.
Results: Mothers of adolescents with optimal diabetes control exhibited significantly higher scores in the so[1]ciability dimension of emotional intelligence compared to those whose children had suboptimal diabetes control (p = 0.029). No statistically significant association was found between coping strategies and diabetes management in adolescents with type 1 diabetes (p > 0.05). However, maternal emotional intelligence was positively correlated with both problem-focused (rho = 0.669, p < 0.001) and emotion-focused coping strategies (rho = 0.321, p = 0.005), while lower emotional intelligence was significantly associated with avoidant coping (rho = -0.434, p < 0.001).
Conclusions: The sociability dimension of maternal emotional intelligence was positively associated with opti[1]mal diabetes management in adolescents with type 1 diabetes. Higher maternal emotional intelligence predicted the use of adaptive coping strategies, specifically problem-focused and emotion-focused coping, whereas lower emotion[1]al intelligence was linked to avoidant coping strategies.
Practical Implications: Interventions aimed at enhancing the sociability aspect of emotional intelligence in mothers may improve their social functioning and, consequently, facilitate better diabetes management in their ado[1]lescent children.
Keywords: type 1 diabetes, emotional intelligence, coping strategies, diabetes management.
