Kebutuhan energi Listrik terus meningkat setiap tahunnya, sehingga diperlukan pembangkit listrik yang handal dan optimal. Penelitian ini bertujuan untuk melakukan analisis variasi pembebanan terhadap konsumsi bahan bakar spesifik pembangkit batubara, heat rate dan biaya produksi listrik di PLTU Asam Asam Unit 4. Pengoperasian pada beban terbaik akan mengurangi biaya produksi listrik dan memperoleh pembangkit yang efisien. Analisis energi input-output menggunakan data commisioning dan performance test menunjukkan bahwa semakin besar beban unit PLTU Asam Asam akan semakin baik kinerjanya yaitu efisiensi thermal 22,08% pada beban rendah 32 MW naik menjadi 30,33% pada beban tinggi 65 MW. Kenaikan kinerja pembangkit ditunjukkan dengan turunnya heat rate, yaitu nilai Gross Plant Heat Rate (GPHR) 3890,10 kcal/kWh pada beban rendah turun menjadi 3108,94 kcal/kWh pada beban tinggi. Turunnya konsumsi bahan bakar akan membuat harga listrik yang dibangkitkan semakin murah, yaitu biaya pokok produksi sebesar Rp 478,46/kWh pada beban rendah 32 MW turun menjadi Rp 419,24/kWh pada beban tinggi 65 MW.

Authors: Myroshnychenko D. , Pikovskyi M. 
Published: December 2024

Goal. To evaluate the resistance of tea-hybrid and floribunda roses to black spot caused by the fungus Diplocarpon rosae F.A. Wolf. (Marssonina rosae (Lib.) Died.).
Methods. Laboratory — for diagnosis of the disease and identification of its causative agent. Field — visual assessment of the distribution and degree of development of black spot (on a 6-point scale) on rose varieties under conditions of a natural infectious background. Mathematical and statistical — to assess the reliability of experimental results.
Results. The conducted studies show that during the growing seasons of 2022—2023, black spotting was widespread on all varieties of hybrid tea roses. The intensity of disease development ranged from 30 to 70%. The average lesion score was 1.5—3.5. Ascot, Fiesta and Charming Piano varieties were noted to have the lowest degree of damage (30%). Among roses of the floribunda group, the spread of the disease was in the range of 25—100%, and its development was from 5 to 70%. The average damage score of different varieties was in the range of 0.25—3.5. The least amount of black spotting was seen on plants of the Blu fo Y variety. At the same time, its intensity of damage was 5%. There were no immune groups among rose varieties of two garden groups. Of the 12 varieties of tea-hybrid roses, highly resistant ones were also not found. 3 varieties were resistant, 6 were moderately resistant, and 3 were susceptible. Of the 11 floribunda rose varieties examined, one variety was characterized by high resistance, 3 were resistant, 5 were moderately resistant, and 2 were susceptible.
Conclusions. According to the results of screening for resistance to black spot, 23 varieties of garden roses did not find immune roses among them. All studied varieties were affected by the causative agent of the disease D. rosae against a natural infectious background. Among the hybrid tea roses, Ascot, Fiesta and Charming Piano varieties are classified as resistant. The Blue Pho Yu variety (floribunda roses) was characterized by high resistance. Floribunda roses Sim Salabim, Bernstein and Four Elis were resistant to the disease. These varieties can be recommended for use in urban landscaping.

Goal. To investigate the effect of humic preparations on the efficiency of vegetable crops protection against diseases.
Methods. Informational and analytical (collection of materials and analysis of literary sources), field research (setting up experiments, monitoring of plant development, assessment, harvesting), mathematical and statistical (processing of research results). Humic preparations used vere Gumifield, w.g. (potassium salt of humic acids, 720 g/ kg), and Fulvital plus, WP (fulvic acids, 200 g/kg + microelements, 75 g/ kg) were used separately and in mixtures with fungicides for spraying plants during vegetation period. Experiments were conducted on cucumbers, tomatoes, white cabbage.
Results. During the years of research downy mildew dominated on cucumber and dry spot or alternaria — on tomato and white cabbage crops. Humic preparations, when applied separately, restrained the development of diseases on tomatoes at the level of 59—64%, on cucumbers — at the level of 46—69%. The protective effect was much higher when mixtures of humates with fungicides were used. Combined application of preparations Gumifield, w.g., 100 g/ha with Ridomil Gold MC 68 WG, w.g. (Metalaxyl-M, 40 g/ kg + mancozeb, 640 g/kg), 2 kg/ha and Fulvital plus, WP 150 g/ ha with Ridomil Gold MC 68 WG, w.g., 2 kg/ha on tomatoes ensured efficiency on average level of 70.6 and 73.5% respectively. Application of mixtures Gumifield, w.g., 100 g/ha with Acrobat MC, w.g. (dimethomorph, 90 g/ kg + mancozeb, 600 g/ kg), 1.5 kg/ha and Fulvital plus, WP 150 g/ha with Acrobat MC, w.g., 1.5 kg/ha on cucumbers ensured efficiency at level of 74.7% and 75.2%. On white cabbage the efficiency of mixtures of Rovral Aquaflo, SC (iprodione, 500 g/l), 1 l/ha with Gumifield, w.g. 100 g/ ha and Rovral Aquaflo, SC, 1 l/ha + Fulvital plus, WP 150 g/ ha was on average 70.8% and 77.4%, respectively. These results were close to or exceeded the protective effect of fungicides at full application rates. The use of humic preparations contributed to the increase in the yield of crops. The yield increase on various crops was from 10 to 21%.
Conclusions. Humic preparations have a positive effect on the growth, development and productivity of vegetable crops. The use of humic preparations alone and in mixtures with fungicides significantly limits damage to plants by diseases during the growing season and increases the yield of crops. The protective effect of humic preparations in mixtures with fungicides with reduced rates was at the level of fungicides with full rates. Due to the use of humic preparations, the pesticide load on the agrocenosis is reduced and the safety of vegetable products is increased.

The Effects of Adaptation of Circumcision Age Set System into the Lineage System of the Tigania in the Pre-Colonial Period Circa, 1850-1908
Authors: Ntongai Igweta Dancan , Muraya Martha 
Published: December 2024

The purpose of this study was to analyze the context of the adaptation of the circumcision age set system on the lineage system of the pre-colonial Tigania circa 1850s-1908. It investigated the cultural dynamics which resulted in the adoption of the circumcision age set system and how it adapted itself in a lineage society. Specifically, the study examined the effects of such adaptation on the social-cultural organization of the pre-colonial Tigania which was a predominantly lineage-based society. The research was interpreted within the theories of social structuralism and instrumentalism theories, which were used to analyze the functionality of the circumcision age set system and the impacts of circumcision age set adaptation by the pre-colonial Tigania. The study employed a descriptive research design. The study location was in Tigania, Meru County with a population of 316, 341 targeting the population with knowledge of the age set system. A sample size of 40 respondents aged 60 years and above based on the concept of data saturation was selected. This sample was selected from the target population through purposive and snowballing sampling procedures. The respondents at this age possessed less diluted information as they acquired it from their parents or grandparents on age-set adaptation. The study also collected data from individuals who were younger but seemed resourceful as a result of education and community leadership experience. The interview guide was used for data collection. Due to the nature and the scope of the study, the data was mainly collected from secondary and oral sources and then corroborated. The data collected was analyzed qualitatively and presented thematically. The research was carried out with strict adherence to the ethics of research. The study found out that when pre-colonial Tigania adopted circumcision the existing lineage system was significantly affected in such a way that, the age set system played a complementary role in pre-colonial Tigania. The age set system expanded the scope of social functions as it cut across the clan boundaries. The clans became more organized, stronger, and safer. Consequently, the adoption and adaptation of the circumcision age set by the pastoralists’ communities strengthened their clan system hence, their survival. This study sheds light on academia and society on how such cultural adaptations influenced the existing structures of the recipient African societies. Hence, contributes to knowledge of the social and cultural history of pre-colonial Tigania and explains how cultural adaptation in pre-colonial African societies unfolded.

The article shows the necessity and relevance of creating new ships for cruise routes along the rivers of the Russian Federation. The names of hydrofoils built are listed. It is shown what the designers are guided by when developing a drawing of the general location of the vessel. Some changes in the requirements and recommendations of regulatory documents for the design and construction of new generation vessels compared to ships built in the 60s are given. Some characteristics of ships and the area of hydrofoil vessels, such as Comet 120M, Meteor 120R, Valdai 45R, are presented. A comparative analysis of the indicators for calculating the areas and volumes of the premises of the new generation SEC and ships built in the 60s of the last century is given. Dependency graphs are constructed to estimate the volume of the engine room, the total volume of peaks, and the area of the conning tower of marine and river hydrofoils. Formulas are given for determining the volume of the engine room and the volumes of the forepeak and afterpeak at the initial stage of ship design. Conclusions are drawn about the need for recalculation of the need for recalculation of indicators for calculating the areas and volumes of hydrofoil vessels.

Abstract
Many microlensed stars discovered by JWST closely follow the winding critical curve of A370 along the “Dragon Arc” with m

AB
> 26.5, which we show comprises asymptotic giant branch stars microlensed by the observed level of diffuse cluster stars, corresponding to ≃1% of the dark matter density. Most events appear along the inner edge of the critical curve, following an asymmetric band of width ≃4.5 kpc that is skewed by −0.7 ± 0.2 kpc. This asymmetry, we argue, follows from the parity difference in caustic structure inherent to microlensing that extends to higher magnification in the negative parity regions. This parity difference predicts a modest net shift of −0.04 kpc to the inside of the cluster critical curve within a narrower band of ≃1.4 kpc than observed. Adding cold-dark-matter-like subhalos of 106−8
M
⊙ doubles the width, but detections are predicted to favor the outside of the critical curve, where the subhalos generate local Einstein rings, and subhalos inside the critical curve depress the magnification, reducing microlensing. Instead, the density perturbations of “wave dark matter” as a Bose–Einstein condensate (ψDM) can generate a wide band of corrugated critical curves with a large negative asymmetry. We find that a de Broglie wavelength of ≃10 pc reproduces the observed width of 4.5 kpc, with a negative skewness ≃−0.6 kpc, like the data, corresponding to a boson mass of ≃10−22 eV, in agreement with dwarf galaxy dynamical estimates. Independently, we also find clear asymmetry in the Jupiter Arc, with 12 microlensed stars lying along the inside of the critical curve, like the Dragon Arc.
Trauma Centers: A Transformation Needed to Save Lives
Authors: Caselli-Belem R. , Lins Renato Diniz 
Published: December 2024

Summary
O trauma é responsável por 5,8 milhões de mortes anuais no mundo, sendo 90% em países de baixa e média renda. Centros de trauma especializados são essenciais para melhorar a sobrevivência de pacientes gravemente feridos, mas muitos países em desenvolvimento enfrentam desafios para estabelecer esses serviços. O Hospital de Base do Distrito Federal (HBDF), desde sua fundação em 1960, sempre foi referência em casos complexos, mas também enfrentava superlotação, falta de recursos e equipes sem treinamento específico para trauma. Em 2011, após adquirir experiência em Tel-Aviv, Israel, e outras experiências internacionais, iniciamos um projeto para transformar o HBDF em um centro especializado em trauma, com apoio irrestrito da alta gestão do hospital e apoios e parcerias com outros serviços. A equipe do hospital começou a treinar e implementar protocolos de atendimento ao trauma, o que resultou na criação do Serviço de Cirurgia de Trauma e, em 2013, no lançamento de um programa de residência nessa área. Entre 2018 e 2021, o serviço de trauma do HBDF conseguiu reduzir a mortalidade na sala de admissão de trauma em 49%. A experiência do HBDF mostra que a criação de Centros de Trauma em países em desenvolvimento pode depender mais de organização e mudanças culturais do que de grandes investimentos financeiros. A padronização de procedimentos e o treinamento contínuo fazem uma diferença significativa, melhorando os resultados para os pacientes e a qualidade do atendimento hospitalar.
Frailty among Older Adults Who Developed Acute Coronary Syndrome during Hospitalization for Noncardiac Illness and Their Outcome: A Prospective Observational Study
Authors: David Arun , Vijayakumar Priya , Vijayakumar M 
Published: December 2024

Abstract

Background:
Atypical presentations of acute coronary syndrome (ACS) delay its recognition and treatment in older adults. During hospitalization, functional decline and delirium which are common to elder patients, lead to prolonged hospitalization, frailty, and poor clinical outcome. Steps taken for its prevention are usually not considered the top priority by the cardiologist. The present study was conducted to identify frailty among older adults who developed ACS during hospitalization for noncardiac illness and their outcome.

Materials and Methods:
Three hundred and ten older adults with ACS were included from June 26, 2020, to October 13, 2020. Subjects were divided into those admitted primarily due to an ACS (Group I, n = 94) and those developing ACS following admission for noncardiac illness (Group II, n = 216). Comorbidities, medications, investigations, management, outcome, and clinical frailty scale were compared between the two groups at the time of admission, after 30 days, and after 6 months.

Results:
Majority of them had non-ST elevation ACS (90.2%) in Group II, and acute kidney injury (27.1%) was the most common reason for admission. Optimum management was given to a lesser extent due to the current clinical condition of these patients. Frailty and physical disability during hospitalization and follow-up were more in Group II.

Conclusion:
Clinicians must be vigilant for the development of frailty when an older adult is admitted to the hospital, as early detection and optimum management provide better clinical and functional outcomes.
Adult Presentation of Anomalous Left Coronary Artery from the Pulmonary Artery with Severe Mitral Valve Regurgitation from Flail Posterior Leaflet
Authors: Nalawade Digvijay D , Shetty Prakyath , Sadgir Anirudha , Bari Sanket 
Published: December 2024

Abstract
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly, which usually presents in infancy, and survival to adulthood is very rare, around 10–15%. We report a 46-year-old female with no risk factors, who presented with a history suggestive of acute left heart failure of two weeks duration. Echocardiography revealed acute severe mitral regurgitation (MR) with flail posterior mitral leaflet (PML) due to chordae tendinae rupture (CTR) with normal left ventricular function and dimensions. There were no features suggestive of infective endocarditis, rheumatic or myxomatous affection of mitral valve. During preoperative workup, coronary angiography revealed the presence of ALCAPA which was confirmed by computed tomography. The patient underwent successful surgical repair of ALCAPA along with mitral valve replacement. The case underscores unusual association of ALCAPA in an adult age with acute severe MR secondary to flail PML due to CTR with a possible ischemic causal relationship.
