The goal of combined economic and emission dispatch (CEED) in the power system is to solve the economics management of generators in order to achieve both minimum fuel prices and pollution levels while meeting load demands and operating limits. The Search and Rescue (SAR) optimization methodology is developed in this study to address the CEED problem, and the results gained are compared with the Evolutionary Programming and Flower Pollination Algorithm methods. Those analyses are able to evaluate the effectiveness as well as the rate of convergence of the methods under consideration. In general, the CEED problem is initially considered a bi-objective problem that has been turned into a single objective function by the use of the price penalty element in its solution. Both solutions were tested on an IEEE 10-Generator 39-Bus System, which has a valve point impact with transmission loss. MATLAB is additionally utilized to run modeling for the evaluated system, with each system subjected to three separate load demands. The results reveal that the SAR technique performs better because it generates resilient and effective solutions to the CEED problem with the lowest fuel price, greenhouse gas emissions, CEED price, and power loss.

Published: April 2024

A 3 × 2 (fish species × culture system) factorial design experiment was conducted to compare productivity of empurau (Tor tambroides), jelawat (Leptobarbus hoevenii) and red hybrid tilapia (Oreochromis sp., control) cultured in recirculating aquaculture system (RAS) and aquaponics system. Growth performance, feed conversion ratio (FCR) and survival rate of fish were evaluated, and water quality of all tanks throughout the 70-days experiment was determined. In the present study, FCR of tilapia, empurau and jelawat tended to be lower in aquaponics than RAS, while no significant differences (P>0.05) on weight gain (WG) and specific growth rate (SGR) between RAS and aquaponics for each fish species were observed. Although tilapia had significantly higher WG and SGR, and lower FCR compare to empurau and jelawat, the survival rate of empurau and jelawat were higher than tilapia, regardless of the culture system. Between empurau and jelawat, better growth performance was observed in aquaponics than in RAS. Significantly higher (p<0.05) ammonia and nitrite concentrations were shown in RAS tanks as compared to aquaponics tanks, regardless of the fish species. Jelawat might have wide range tolerance to ammonia as no mortality in both RAS and aquaponics, while tilapia and empurau had higher survival rate in aquaponics than RAS. In summary, aquaponics appears to be a viable approach to enrich variety and improve fish production in an environmentally responsible manner. Therefore, it is plausible to advocate for the use of aquaponics as a sustainable methods of farming native fish species in Malaysia.

Published: April 2024

Three new hexahydropyrimidine derivatives 1a – 1c were successfully synthesized using the Mannich-type reaction. Furthermore, the synthesis of three amino bases 2a – 2c was achieved through the reduction reaction of pyrimidine compounds using hydrazine, followed by the substitution reaction of nitro groups at diverse positions. Subsequently, one of the synthesized amino base derivatives 2c underwent conversion into seven Schiff bases 3a – 3g via a condensation reaction involving the aforementioned amino base derivative and a selection of benzaldehyde derivatives. Four amide compounds 4a – 4d have been synthesized by a reaction of the secondary amine group in the pyrimidine ring with benzoyl chloride. The products were subjected to comprehensive characterization employing rigorous analytical techniques, including FT-), 1H-NMR (Proton Nuclear Magnetic Resonance Spectroscopy), and LC-MS (Liquid Chromatography–Mass Spectrometry). Additionally, the Molecular Electrostatic Potential (MEP) study was carried out to further investigate the properties of the synthesized compounds. The yields of the three methods used to synthesise new hexahydropyrimidine derivatives varied depending on the specific substituents added to the aromatic ring.

Authors: Elabbadi O.E. , Benniou R. , Louahdi N. , Guendouz A.
Published: April 2024

Background: The low amount of rainfall and high loss of soil water through evaporation during spring; there are the dominant factors affecting crop production in semi-arid region. Methods: A field study was conducted during two cropping seasons of durum wheat (Triticum durum Desf.) to compare the effect three tillage operations viz., no-tillage, minimum tillage and conventional tillage. Result: There was variation in precipitation between the experimental years (dry and rainfall seasons). All the parameters registered significant differences between the cropping seasons. Soil water storage to a depth of 0.4 m was higher under no tillage (NT) and minimum tillage (MT) in the first year as compared to conventional tillage (CT) in the first year. During the second year, the soil water content was same under different tillages. The thousand-kernel weight registered significant differences among the tillage operations viz., no till (36.09-50.36 g), minimum tillage (30.93-46.81 g) and conventional tillage (28.31-45.05 g) in the two seasons, respectively. Under no till treatment water use efficiency was high from grain production. The no till also recorded high grain yield of 1.07 t/ha and 4.7 t/ha during first and second year, respectively. The lack of rain was more detrimental in conventional tillage system as compared to no till and minimum tillage.
On some classes of systems of differential equations
Authors: Rodina Ludmila I.
Published: April 2024

We consider an autonomous system of differential equations
x ̇=f(x), where x∈R^n,
the vector function f(x) and its derivatives ∂f_i/∂x_i (i,j=1,…,n) are continuous. Three classes of autonomous systems are identified and the properties that systems of each class possess are described.

We will assume that the system belongs to the first class on the set D⊆R^n, if the right parts of this system do not depend on varibles x_1,…,x_n, that is this system has the form x ̇=C, where C∈R^n, x∈D. We will assign to the second class the systems that are not included in the first class, for which the next condition is met “each of the function f_i is increasing on the set D⊆R^n with respect to all variables on which it explicitly depends, with the exception of variable x_i, i=1,…,n”. Solutions of systems of the first and second classes have the property of monotonicity with respect to initial conditions.

We will assign to the third class the systems that are not included in the first class, for which the condition is met “each of the function f_i is decreasing on the set D⊆R^n with respect to all variables on which it explicitly depends, with the exception of variable x_i, i=1,…,n”.

The conditions for the absence of periodic solutions for autonomous systems of the second order are obtained, complementing the known Bendikson conditions. It is proved that systems of two differential equations of all three specified classes cannot have periodic solutions.
A criação dos grupos escolares no contexto da República
Authors: Ramos Géssica Priscila
Published: April 2024

Este artigo objetiva apresentar e discutir aspectos gerais da história da escola primária pública paulista, com ênfase no nascimento e na institucionalização dos grupos escolares no estado de São Paulo, entre 1893 até 1920. Foi desenvolvido a partir de análise bibliográfica, com suporte legal. Mostra que a criação dos grupos escolares representou uma tentativa de inovação da educação primária, ao conceber essa escola a partir do modelo de ensino intuitivo, de uma organização renovada (em seus espaços e tempos) e da oferta de um padrão de qualidade pretensamente superior à de qualquer outro modelo de escola então existente.  Todavia, ao se localizarem maiormente nos espaços urbanos centrais, ao menos até 1920, rompeu com o próprio sonho republicano da unidade formativa, permitindo a legalização de uma educação diferenciada: a rural e a urbana, a central e a periférica.

Authors: Sağlam Osman , Ersöz Gülçelik Neşe , Omma Tülay , Karaca Anara , Aral Yalcin , Gürsoy Gül
Published: April 2024

Amaç: Diyabetin hızla artan prevalansı, onu önemli bir küresel sağlık sorunu haline getirmiştir. Mevcut tedavi seçenekleri olsa da, tedavide yenilikçi yaklaşımlara ihtiyaç vardır. Hem molekülünün hem oksijenaz-1 ile parçalanması sonucu CO, bilirubin ve Fe/Ferritin ortaya çıkar. Yapılan hayvan deneyleri, hem oksijenaz-1 indüksiyonu sonucu ortaya çıkan ürünlerin inflamasyon, oksidatif stres ve apoptozu hafiflettiği ve hiperglisemiyi azalttığı gösterilmiştir. Bizde, diyabetli kadınlarda glisemik durum üzerine serum hem oksijenaz-1'in etkisinin olup olmadığını incelemeyi amaçladık.
Gereç ve yöntem: Polikliniğe başvuran 63 kadın hasta (31'i diyabetik, 32'si kontrol) çalışmaya dahil edilmiştir. Çalışmaya akut ve kronik böbrek yetmezliği olan hastalar, akut veya kronik karaciğer hastalığı olan hastalar, akut enfeksiyonu olan hastalar, vücut kitle indeksi (VKİ) ≤18 kg/m2 veya ≥35 kg/m2 olan hastalar ve 18 yaşından küçük ve 65 yaşından büyük hastalar dahil edilmemiştir.
Bulgular: Serum ferritin hasta grubunda kontrol grubuna kıyasla anlamlı olarak daha yüksekti (p = 0.028). Serum total bilirubin ve serum hem oksijenaz-1 iki grupta benzerdi (sırasıyla p = 0.260, p = 0.426).
Sonuç: Çalışmamızda diyabet grubundaki serum ferritin düzeyinin kontrol grubuna göre anlamlı ölçüde daha yüksek olması ferritinin diyabet patogenezindeki olası rolünü desteklemektedir. Bununla birlikte, serum total bilirubin düzeyleri ve serum hem oksijenaz-1 düzeylerinde gruplar arasında önemli bir fark gözlenmemiştir. Bu durum, serum ferritin ile glisemik parametreler arasındaki ilişkinin doğrudan hem moleküllerinin hem oksijenaz-1 tarafından parçalanması ile ilişkili olmayabileceğini düşündürmektedir.

Published: April 2024

Perovskite solar cells have demonstrated remarkable progress in recent years. However, their widespread commercialization faces challenges arising from defects and environmental vulnerabilities, leading to limitations in energy conversion efficiency and device stability. To overcome these hurdles, passivation technologies have emerged as a promising avenue. These passivators are strategically applied at the interface between perovskite absorbers and charge transport layers to mitigate the adverse effects of defects and environmental factors. While prior reviews have predominantly focused on experimental observations, a comprehensive theoretical understanding of the passivators has been lacking. This review focuses on recent advancements in first-principles density functional theory studies that delve into the fundamental properties of passivators and their intricate interactions with perovskite materials and charge transport layers. By exploring the atomic-level roles of passivators, this review elucidates their impact on critical parameters such as open circuit voltage (Voc ), short circuit current density (Jsc ), fill factor, and the overall stability of perovskite solar cells. The synthesis of theoretical insights from these studies can serve as guidelines for the molecular design of passivators with the ultimate objective of advancing the commercialization of high-performance perovskite solar cells.

Penggunaan antibiotik menjadi pilihan utama untuk mengobati ISPA yang disebabkan oleh bakteri. Namun, penggunaan antibiotik yang tidak tepat dan berlebihan dapat menyebabkan efek samping dan resistensi antibiotik, yang menjadi masalah kesehatan global. Penelitian ini bertujuan untuk menganalisis penggunaan antibiotik pada pasien rawat inap dengan ISPA di rumah sakit swasta. Metode penelitian menggunakan Single Cohort dengan menggunakan data rekam medik sebagai sumber utama. Sebanyak 94 dari 134 pasien mendapatkan antibiotik. Pemeriksaan WBC masih menjadi parameter pemberian antibiotik (p<0,05). Pemberian antibiotik kategori Watch masih mendominasi pilihan antibiotik empiris (82,03%). Penggunaan ceftriaxone pada ISPA sangat besar dibandingkan antibiotik lain (DDD/100 patient days = 42,37). Hasil penelitian menyimpulkan bahwa antibiotik yang diberikan kepada pasien dengan Infeksi Saluran Pernapasan Akut (ISPA) di rumah sakit ini sesuai untuk melawan bakteri penyebab ISPA. Meskipun penggunaan antibiotik golongan Access memerlukan pertimbangan lebih lanjut, Ceftriaxone menonjol sebagai antibiotik yang paling sering diresepkan untuk pasien ISPA, dengan total DDD/100 hari pasien sebesar 42,37. Kata Kunci: Antibiotik, DDD, Infeksi Saluran Napas, Antibiotik Aware, Seftriakson The utilization of antibiotics represents the primary therapeutic approach for managing bacterial-induced Acute Respiratory Infections (ISPA). Nevertheless, indiscriminate and excessive antibiotic usage can give rise to adverse effects and antibiotic resistance, constituting a pervasive global health concern. This study endeavors to scrutinize antibiotic utilization among inpatients diagnosed with ISPA within a private hospital. Employing a Single Cohort design, medical records serve as the principal data source. Among 134 patients, 94 were administered antibiotics. Notably, White Blood Cell (WBC) examination emerges as a pivotal parameter influencing antibiotic administration (p<0.05). The Watch category continues to predominate as the preferred choice for empirical antibiotics (82.03%). Ceftriaxone emerges as the predominant antibiotic in ISPA treatment, surpassing other counterparts (DDD/100 patient days = 42.37). Findings underscore the absence of established protocols governing antibiotic usage in ISPA patients within the hospital, accentuating the imperative role of the Antimicrobial Stewardship Team in guiding and overseeing antibiotic practices. The study's findings suggest that the antibiotics administered to patients with Acute Respiratory Tract Infections (ISPA) in this hospital are fitting for combating the bacteria responsible for ISPA. While the utilization of Access group antibiotics warrants further consideration, Ceftriaxone stands out as the most frequently prescribed antibiotic for ISPA patients, with a total DDD/100 patient days of 42.37.

Penggunaan antimikoba pada pasien bedah umum pasca operasi digunakan untuk mencegah terjadinya infeksi luka operasi. Namun pada penggunaan antimikroba yang tidak bijak dapat menyebabkan terjadinya resistensi antibiotik. Jika sudah terjadi resistensi antibiotik hal tersebut dapat menyulitkan terapi. Oleh karena itu, perlu dilakukannya pengendalian penggunaan antibiotik dengan cara penggunaan yang rasional / bijak. Pencegahan terjadinya resistensi antimikroba dapat dilakukan dengan menyesuaikan pemberian antibiotik pada pedoman terapi serta dapat dilakukan evaluasi secara kuantitatif maupun kualitatif secara berkala. Tujuan penelitian ini adalah untuk mengetahui nilai DDD dari antibiotik di RSAU Efram Harsana Lanud Iswahyudi. Penelitian ini merupakan penelitian deskriptif-analitik dengan desain cross sectional dengan pengambilan data secara retrospektif pada pasien bedah umum RSAU Efram Harsana Iswahjudi selama peridoe Juli-September 2019. Dari laporan rekam medis peresepan antibiotik sebanyak 401 dari 339 rekam medis diperoleh hasil dengan pemakaian jenis antimikroba tertinggi  golongan sefalosporin ceftriaxon 15,909/100 pasien-hari dan pemakaian jenis antimikroba terendah yaitu ceftazidim 0,098/100 pasien-hari.  Kata Kunci: Pasien Bedah Umum, Antibiotik, ATC/DDD, Resistensi Antimikroba, DDD/100. The use of antimicrobials in postoperative general surgery patients is used to prevent wound infection. However, the use of antimicrobials that are not wise can cause antibiotic resistance. If antibiotic resistance has occurred this can complicate therapy. Therefore, it is necessary to control the use of antibiotics by means of rational use. Prevention of antimicrobial resistance can be done by adjusting the administration of antibiotics in the therapeutic guidelines and periodic quantitative and qualitative evaluations can be done. This study aims to determine the DDD value of antibiotics in general surgery patients at Efram Harsana Hospital Iswahjudi Lanud. This research is a type of descriptive study with a retrospective cross sectional design using ATC / DDD analysis. Data obtained from the medical records of general inpatients in Efram Harsana Hospital peridoe July-September 2019. From the medical record report prescribing antibiotics as many as 401 out of 339 medical records obtained results with the use of the highest type of antimicrobial cephalosporin ceftriaxon 15,909 DDD / 100 days of treatment and 100 days of treatment and obtained the results of the use of the highest antimicrobial type cephalosporin ceftriaxon 15,909 DDD / 100 days of hospitalization and The lowest use of antimicrobial types was ceftazidim 0.098 DDD / 100 days of hospitalization.

Authors: Wahyuningtias Eko , Kusumawardhani Ratih
Published: April 2024

Purpose – This research aims to examine the influence of intellectual capital on company performance, analyze the moderating effect of revenue diversification, and provide additional insight into intellectual capital.Design/methodology/approach – This research uses 38 banks in Indonesia that are listed on the Indonesia Stock Exchange (BEI) out of a total of 47 banks as research samples. The collected data was analyzed using linear regression and moderated regression analyses to test the effect of intellectual capital on company performance and the moderating impact of income diversification on intellectual capital and company performance.Findings – The results of the regression analysis show that intellectual capital (VAIC) has a positive effect on company performance. In contrast, income diversification is having a moderating impact on intellectual capital and company performance. The intellectual capital component has varying influences on company performance. Whereas VACA has a positive effect on company performance, VAHU also has a positive effect on company performance. In contrast, STVA does not affect company performance. Based on the moderation test, income diversification does not moderate the relationship between intellectual capital components and company performance.Research limitations/implications – This research uses the VAIC method to measure intellectual capital using financial report benchmarks. Future researchers should consider using new techniques that are more accurate and comprehensive in measuring intellectual capital. Thus, further research will provide a more precise picture of intellectual capital's influence in improving banking companies' performance.Practical implications – This research shows that banking activities with an intellectual capital orientation tend to improve company performance. So, it is recommended for banking companies to utilize and develop the intellectual capital they have.Originality/value – This research provides an understanding of intellectual capital. This research also contributes to developing economic theory related to intellectual capital and company performance.

Published: April 2024

Objective: The purpose of this study was to determine the character of ice cream made from goat’s milk kefir (GMK) combined with mono-acylglycerol (MAG).

Methods: GMK was produced by pasteurized goat’s milk (85oC for 15 s) and 2% kefir grain. Ice cream mix (ICM) was produced by GMK, MAG (T0= 0%, T1= 0.25%; T2= 0.50%; T3= 0.75%), 4% sucrose, and 0.1% salt. The results of observations processed using Analysis of Variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) if there were a significant difference between treatments.

Results: Es puter (EP) made from GMK in combination with MAG has a distinctive character against T0 (control). The use of GMK decreases the pH value, thereby increasing the lactic acid and ethanol content which brings out the acidity of the product (p<0.05). In addition, increasing MAG concentration can improve the EP’s overrun to make the product more melt resistant (p<0.05). The use of GMK combined with MAG can support the viability of lactic acid bacteria (LAB) and yeast through storage in the freezer. The number of viable LAB and yeast meets WHO standards to obtained health benefit from consuming probiotic ice cream.

Conclusions: To conclude, EP made from GMK in combination with 0.50% MAG was proved to be the best treatment.

Published: April 2024

The engineering behavior of frozen soils is critical to the serviceability of civil infrastructure in cold regions. Among various geophysical techniques, electrical resistivity imaging is a promising technique that is cost effective and provides spatially continuous subsurface information. In this study, under freeze–thaw conditions, we carry out lab–scale 1D electrical resistivity measurements on frost–susceptible soils with varying water content and bulk density properties. We use a portable electrical resistivity meter for temporal electrical resistivity measurements and thermocouples for temperature monitoring. Dynamic temperature-dependent soil properties, most notably unfrozen water content, exert significant influences on the observed electrical resistivity. Below 0 °C, soil resistivity increases with the decreasing temperature. We also observe a hysteresis effect on the evolution of electrical resistivity during the freeze–thaw cycle, which effect we characterize with a sigmoidal model. At the same temperature, electrical resistivity during freezing is consistently lower than that during thawing. We have implemented this sigmoidal model into a COMSOL finite element model at both laboratory and field scales which enables the simulation of soil electrical resistivity response under both short–term and long–term sub–freezing conditions. Atmospheric temperature variations induce soil temperature change, and thereby phase transition and electrical resistivity change, with the rate of change being a function of the depth of investigation and soil properties include initial water content and initial temperature. This study advances the fundamental understanding of the electrical behaviors of frozen soils and enhance the application of electrical geophysical investigations in cold regions.
