Authors: Yevsyeyeva N. , Sukhonos R. , Krestjaninov S. 
Published: March 2024

Purpose. It is to determine the functions of the temperature of the coolant on the time of heating of the cooling system of the small internal combustion engine in two variants – with a coolant pump with a constant mechanical drive, and with an electrical driven pump.
Research methods. Methods of analysis of scientific literature and theoretical generalization, methods of statistical analysis, synthesis, observation, method of project development have been used. The graphs were treated with the least squares with the finding a polynomial function of temperature from time. The accuracy of the results is evaluated by the correlation index R2.
Results. Modern internal combustion engines cooling systems, including the direct driven coolant pump, are considered. The dependence of the engine heating temperature on the time of its operation with a mechanical drive of the pump and a drive from the electric motor was found. Analysis of cooling systems of the modern internal combustion engine with a direct drive of the coolant pump and with a controlled electric drive was carried out.
Scientific novelty. Analysis of the cooling system of the car gasoline engine showed their dependence on the time of heating of the engine during cold start. It is established that engine with electrical driven pump has been found to reduce the heating time, compared to the engine with a mechanical drive of the pump, for one and a half minutes. This provides fuel savings 3 %, at the temperature of the pump motor switching on 130 °C. It is established that the use of the electric driven pump reduces its operation time by almost 50 %.
Practical value. The functions of the coolant temperature dependence on the time of heating of the gasoline engine with the direct driven coolant pump and with the electrical driven pump are determined. This makes it possible to modernize the cooling system of small internal combustion engines.

Authors: Davidyuk A. 
Published: March 2024

Purpose. To determine the effect of modification with powder compositions on the structure and mechanical properties of cast and deformed aluminium alloys.
Research methods. Metallographic analysis, stereometric metallography, testing of strength and plastic properties of cast alloys AL4, AL4C of the Al-Si system and deformed alloys 1545 of the Al-Mg-Sc system, 2219 of the Al-Cu-Mn system in their original and modified state.
Results. Meltings of AL4, AL4C, 1545, 2219 alloys were carried out in the initial state and with melt treatment with a complex nano-disperse modifier of magnesium silicide Mg2Si and silicon carbide SiC with a particle size of 50...100 nm. The optimal content of Mg2Si+SiC (0.10%) for increasing σ0.2 of aluminium alloys was determined. A 1.6-fold reduction in the grain structure of cast alloys was achieved. The dependence of the particle size and the amount of the modifier on the mechanical properties of the alloys was established. In industrial experiments, the most effective particle size of Mg2Si+SiC was established for increasing σ0.2 of AL4, AL4C alloy from 115 to 260 MPa in the as-cast state. The increase in the strength properties of the modified alloys is 44 % compared to the original state.
Scientific novelty. Further development, insight into the influence of melt modification on the parameters of the structure and properties of aluminium alloys was obtained. The use of nanodispersed complex modifier Mg2Si+SiС with a particle size of 50...100 nm is proposed. It has been confirmed that the use of complex nanodisperse modifiers allows you to actively influence the structure and mechanical properties of aluminium alloys.
Practical value. It has been experimentally proven that the rational amount of the introduced complex modifier is 0.10% of the mass of the melt. A significant grinding of the grain structure and an increase in the strength properties of cast and deformed aluminium alloys were achieved as a result of the modification.

Tiada akhir pada suatu pergolakan, selalu timbul pertentangan suatu terhadap yang lainnya. Begitu juga aliran impresionisme pada periode romantik, muncul akibat pertentangan komposer-komposer saat itu menentang formalisme tradisional berupa aturan musik yang diajarkan pada instansi akademik di Paris. Tujuan dari penelitian ini adalah untuk menganalisis keunikan pengolahan melodi, ritmik, dan harmoni yang dilakukan Debussy dalam clair de lune lalu kemudian mengambarkan dan mendeskripsikan temuan hasil analisis. Oleh sebab itu, penelitian inimenggunakan metode deskriptif analisis dengan pendekatan paradigma kualitatif. Ditemukan bahwa Dalam mengolah melodi, Debussy melakukan beberapa hal, seperti membuat suatu garis melodi, mengutamakan langkah second mayor dan minor, penggandaan melodi, melodi tumbuh secara organis, melodi ornamen. Dalam mengolah ritmik, Debussy menggunakan ritme aditif dan pengelompokan nada yang tidak sama. Sedangkan dalam pengolahan harmoni melakukan beberapa disonansi, open chord, appoggiatura, variasi harmoni sebagai unsur vertikal, penggunaan akor pararel, pentatonik, dan whole tone sebagai akor. Debussy membuat karya piano clair de lune sangat khas dengan gayanya sendiri dan mengolahnya secara vertikal dan horizontal. Selain itu karya ini mampu menggambarkan suatu bulan khas dengan cahayanya di malam hari yang begitu cerah, temaram, dan tenang. Hasil penelitian ini diharapkan Sebagai tambahan referensi atau bahan kajian repertoar yang dapat membantu dalam menganalisis suatu karya musik, khususnya karya Claude Debussy.Kata kunci: pergolakan, clair de lune, Claude Debussy, Bulan, Stylistic
Chronic oral non-healing ulcer with a history of tobacco consumption leads to malignancy: A prospective cross-sectional study in Western Maharashtra, India
Authors: Byakodi Jyoti Raghavendra , Byakodi Sanjay Satappa , Byakodi Raghavendra Satappa 
Published: March 2024

Oral ulcerations are more frequently seen in day-to-day dental practice nowadays. These ulcers are usually ignored in initial presentations. The oral mucosa has a good healing prospectus and hence nonmalignant lesions heal fast. The oral ulcers that don't heal form a significant number and are presented to dental clinics for evaluation. Usually, oral ulcers with a habit of tobacco consumption are frequently encountered. Tobacco has been traditionally used in India in various forms like smoking and chewing. But nowadays tobacco has been mixed with many adjuncts and used. They are commercially sold as gutkha pouches. Usually, individuals are exposed to tobacco at a very young age and eat for a longer duration of lifespan (i.e. start young and eat old). This has led to alteration in the oral mucosal defense mechanism and chances for potential malignant conversion are enormous. India has the highest incidence of oral cancer in the world and tobacco is one of the major cause of oral cancer. Hence, in this study, we evaluated patients reporting with chronic oral non-healing ulcers and having tobacco habits for their malignant conversion. Patients reporting to Sharada Dental Hospital Miraj during a period of 5 years from 2017 to 2022 were included in the study. A total of 250 patients with chronic nonhealing ulcers belonging to the semi-urban district of Sangli in Western Maharashtra (India) were studied. All these patients had a positive tobacco consumption history and presented with oral non-healing ulcers with a duration of more than 2 months. An incisional biopsy was taken from the suspected lesion and sent for histopathological evaluation. : A total of 250 patients with tobacco habits were presented with oral non-healing ulcers during the study period. A biopsy was performed for all suspected cases. Out of 250 patients, 201 patients had Squamous cell carcinoma and the other 49 were hyperkeratosis, inflammatory fibrous hyperplasia, irritational fibroma, Pyogenic granuloma, and angiomatous hyperplasia. Among 201 OSCC cases, 162 (80.59%) were males and 39(19.4%) were females. From our study, we can say that chronic oral non-healing ulcer with a positive tobacco consumption history is more likely to be a squamous cell carcinoma.
Idosos portadores de doença renal crônica: o papel da gestão em saúde na cidade de Santa Maria, Rio Grande do Sul
Authors: Rodrigues Bruno Vinicius , Oliveira Jairo Da Luz 
Published: March 2024

<p>Este estudo buscou identificar como se procedeu o processo de falência renal em idosos e as respostas da gestão municipal de saúde no município de Santa Maria. A metodologia utilizada foi a qualitativa, a discussão foi baseada no método dialético-crítico mediante análise epistemológica da realidade proposta por Marx, já a análise e interpretação dos dados foram embasadas pela análise do discurso proposto por Gagneten. Sendo assim, foi possível verificar que a ausência de um sistema público, universal, de saúde, ante a criação do Sistema Único de Saúde, assim como a ausência de políticas públicas voltadas à prevenção e a promoção de saúde foram determinantes para o processo de adoecimento dos entrevistados. Além disso, foi evidenciado que os cuidados necessários para o tratamento das doenças de base foram negligenciados e insuficientes ao longo da trajetória de vida. Nesse sentido, conseguimos verificar a relevância das ações de Atenção Primária para estes pacientes, uma vez que portadores de Diabetes Mellitos e Hipertensão Arterial Sistêmica necessitam incondicionalmente do suporte proveniente das políticas públicas de promoção, prevenção e autocuidado para manutenção e controle de suas respectivas situações de saúde. Não obstante, também foi possível compreender que o processo de adoecimento proveniente das patologias de base supracitas deu-se de forma gradativa e sobretudo, silenciosa. Também identificamos a baixa cobertura de atenção primária no município de Santa Maria e a dificuldade de referenciamento à atenção especializada como fatores preponderantes no processo de falência renal. Assim, com a desassistência da atenção primária frente estes trabalhadores, doenças incapacitantes como a Doença Renal Crônica acabam emergindo silenciosamente durante o processo de envelhecimento, culminando na perda irreversível da função renal e a necessidade de tratamento por hemodiálise para manutenção da vida.</p><p> </p>

Low-birth-weight scorecard for early prevention: the accuracy for predicting low-birth-weight infants based on maternal risk factor
Authors: Utami Sri , Susilaningrum Rekawati 
Published: March 2024

Introduction: Babies with low birth weight (LBW) have a risk of complications and health problems. One of the efforts to prevent LBW births is to detect risk factors in pregnant women. This study aimed to test the accuracy of an early LBW detection scorecard based on maternal risk factors.
Methods: The research design used was observational analytical. The sample in this study was 177 mothers who were registered and delivered at hospitals and public health centers in Surabaya and were selected using a purposive sampling method. The research instruments used were LBW scorecard, maternal medical records, and baby’s scale. The accuracy of the scorecard was measured with Mann-Whitney test, and Receiver Operating Characteristic (ROC) curve.
Results: The LBW scorecard which was based on maternal factors analysis can significantly predict LBW births (p = 0.000). Based on the ROC curve analysis, it was known that the early detection scorecard has a cut-off point of 3.5, and an accuracy of 88.70%, which indicated that the scorecard has high accuracy in predicting LBW.
Conclusions: The LBW early detection scorecards is able accurately to predict the incidence of LBW births. Through analysis and calculation of maternal risk factor, it can be seen whether the mother is at risk of giving birth to a LBW or normal weight baby. Early detection of LBW can improve services for at-risk babies, resulting in a positive impact on their health outcomes.

Published: March 2024

Introduction: Globally, antiretroviral therapy (ART) has been successful in reducing the death rate due to human immunodeficiency virus (HIV). Different conditions in Indonesia mean the death rate due to HIV/AIDS is still high. The problem lies in the low compliance with ART. This study aimed to analyze the correlation between ART adherence with number of CD4, the opportunistic infection (OI) and viral load in PLHIV.
Methods: A quantitative survey with cross-sectional approach was conducted between August – September 2022. As many as 375 PLHIV were recruited and agreed to give consent as research respondents. All respondents completed a questionnaire about ART adherence, OI and had blood taken to check CD4 count and viral load. Analyses were performed using Chi-squared test SPSS version 21 with significance level p<0.05.
Results: A significant relationship was shown between ART adherence and OI (p value= 0.000 with <0.05). The respondents who reported adherence in ART also showed asymptomatic OI. The analysis also showed that ART adherence had significant relationship with CD4 count (p value= 0.000 with <0.05) and viral load (p value= 0.000 with <0.05), respectively. Respondents adherent to taking ART had better level of CD4 and suppressed viral load in the body.
Conclusions: Adherence of antiretroviral therapy is the important factor contributing to the immune status of PLHIV, which has an impact on reducing CD4 count and suppressing viral load, thereby preventing the emergence of OI.
Improving Quality of Life in Geriatric with Pain due to Scoliosis and Old Compression Fracture: A Case Report
Authors: Dewantari Easy Orient , Putriheryanti Arini 
Published: March 2024

Scoliosis frequently causes problems in geriatrics, particularly pain. Pain that persists for a long time can result in a decreased quality of life and disability. Thus, pain management is needed in patients with scoliosis. We report the case of a 71-year-old man referred from the Neurology Department with pain due to scoliosis and an old compression fracture, making him incapable of walking, became dependent, and had a high risk of falling, thus resulting in a decreased quality of life. Physical examination revealed hyperkyphotic thoracal, tenderness and spasms on the paralumbar muscles, with no weakness in the extremities but decreased sensory function on both dorsum of the feet. The patient also had decreased chest expansion. The patient was conservatively managed. The goals of this treatment are to relieve pain, improve sensory function, and improve the quality of life. He underwent a staged rehabilitation program, starting from a combination of Transcutaneous Electrical Nerve Stimulation (TENS) and microwave diathermy, breathing, and core muscle strengthening exercises. After 10 weeks, there was an improvement in pain, risk of falls, chest expansion, and quality of life. Improving the quality of life of geriatric patients requires a multi-dimensional approach. Relieving pain, enhancing cardiorespiratory endurance and preventing falls were the main goals of this patient. Each exercise must be safe considering the patient’s age, health condition, and vertebral fractures. Family support is important to monitor and encourage patient during the program.
