An optimal power flow problem incorporating stochastic wind and solar power through the modified competitive swarm optimization algorithm
Authors: Kumar Naveen , Kumar Ramesh
Published: March 2024

Increasing power demand day by day is the primary concern for power system practitioners and researchers. Generating a large amount of power through thermal power plants is neither economical nor environmentally friendly. The cost of fuel (Coal) is growing gradually as the coal reserves are depleting exponentially. Moreover, the government is imposing strict environmental guidelines on power-generating utilities. All these circumstances restrict the generation of electricity through fossil fuel-based plants. It is of most importance to develop for an alternative to fulfill consumers’ economic and clean energy demand. Based on it, this paper explains minimization fuel cost along with emission, power loss and voltage deviation. Modified competitive swarm optimization (MCSO) algorithm is used to determine optimization. The results obtained from the modified competitive swarm optimization algorithm are compared with the competitive swarm optimization (CSO) algorithm and successive history-based adaptive differential evolution (SHADE-SF) algorithm to verify the efficiency of modified competitive swarm optimization. The work is executed on a standard IEEE 30 bus system, and MATLAB is used as a simulation platform.

Authors: Jha Shyam Sunder , Sudha K. , Kumar Aditya , Sharma Sandeep , Sivagurunathan G.
Published: March 2024

In the ongoing global transition from non-renewable energy sources to renewables such as solar, wind, and tidal power, solar energy plays a predominant role. Take, for instance, the widespread use of solar-powered e-rickshaws. These vehicles require a consistent and lowharmonics DC supply to charge their batteries. However, during overcast days, the solar panels on the e-rickshaws may struggle to provide the necessary power for battery charging, leading to potential interruptions. One effective solution to address this challenge involves implementing a DC-DC converter to maintain a stable voltage supply to the load. Three types of DC converters have been designed and their input-output voltage relations are calculated and compared. All three converters are simulated using MATLAB with an open-loop control approach.

Authors: Sriyanto Sriyanto , Alfitri Alfitri , Widodo Slamet , Sriati Sriati
Published: March 2024

Konsep revolusi ilmiah dari Thomas Kuhn memiliki karakteristik pemikiran dan model filsafat baru yang berpengaruh terhadap sejarah lahirnya ilmu pengetahuan dan filsafat sains. Konsep tersebut juga berpengaruh dalam proses konstruksi maupun rekonstruksi munculnya ilmu pengetahuan baru. Menurut Thomas Kuhn sejarah ilmu pengetahuan digunakan sebagai starting point kajian permasalahan fundamental dalam epistemologi keilmuan. Hal tersebut dikarenakan sains prinsipnya selalu ditandai dengan kuatnya paradigma dan revolusi ilmiah yang terjadi setelah adanya anomaly dan krisis. Fase ini kemudian didefinisikan oleh Thomas Kuhn sebagai fase sejarah lahirnya ilmu pengetahuan baru, dimulai dengan normal science, kemudian terjadi anomali dan krisis. Dengan adanya hal tersebut, kemudian muncul revolusi ilmiah yang menyebabkan lahirnya ilmu pengetahuan baru. Konsep Thomas Kuhn tersebut relevan dengan pengembangan keilmuan operasi pemeliharaan perdamaian dunia (peace keeping operation) dengan tujuan membangun keterbukaan pengembangan operasi pemeliharaan perdamaian dunia terhadap anomali dan krisis serta munculnya revolusi dalam ilmu operasi pemeliharaan perdamaian dunia sehingga memotivasi munculnya paradigma baru di dalam pengembangan konsep operasi pemeliharaan perdamaian dunia. Berbagai pendekatan dalam studi operasi pemeliharaan perdamaian dunia dapat menggunakan beberapa pendekatan, diantaranya normatif, historis, empiris dan pendekatan lainnya dalam rangka penyiapan kapabilitas pembangunan pasukan yang terlibat dalam operasi pemeliharaan perdamaian dunia

DEKOLONISASI
Authors: Imam Maidi
Published: March 2024

Gerakan Dekolonisasi merupakan gerakan bangsa- bangsa yang terjajah terkhususnya anak bangsa yang berada di kawasan benua Asia dan Afrika.Secara politis Dekolonisasi dibidang politik dimulai setelah perang dunia II berakhir dimana Negara Jepang dan Jerman kalah dalam peperangan terasebut muncullah semangat untuk merdeka, atau melepaskan diri dari negara yang menguasainya. India melepaskan diri dari Inggeris, Indonesia melepaskan diri penjajahan Belanda dan Pendudukan Jepang, dan hampir semua negara di Asia Tenggara terjadi Dekolonisasi. Dekolonisasi merupakan proses panjang dari suatu bangsa yang ingin merdeka, jauh sebelum lahirnya para proklamator Seperti Soekarno dan M. Hatta gelombang Dekolonisasi sudah berjalan. Seperti perang Diponegoro, di Jawa Tengah, perlawanan Tuanku Imam Bonjol Sumatera Barat dan Para Pejuang Di Aceh, Maluku. Lonceng kemerdekaan jauh sudah berbunyai sebelum masa politik etis. Politik etis muncul setelah pemerintah Belanda mengadakan kegiatan tanam paksa terhadap Bangsa Indonesia, karena kas Negara Belanda bangkrut disebabkan peperangan di Eropa yang dipicu oleh Belgia yang ingin Merdeka dari Belanda. Dampak dari politk Etis inilah bangsa Belanda memberi kesempatan kepada anak-anak Pribumi untuk dapat mengikuti pendidikan formal Belanda, dengan tujuan agar dapat membantu Pemerintahan kolonial didalam menjalankan tugas-tugas administrasi atau pelayanan publik dan Menjadi BIROKRAT dipemerintahan kolonial Belanda. Namun output dari politik etis itu berkembang tidak sesuai dengan cita-cita Pemerintah kolonial, bahkan kontra produktif, yang melahirkan para pemikir Dekolonisasi yang menyuarakan kemerdekaan dan keadilan bagi bangsa Indonesia atau Hindia Belanda, dengan membuat partai dan perserikatan, seperti Muhammadiyah dan Nahdhatul Ulama, Keinginan kuat dari negara-negara yang terjajah Untuk merdeka mendapat momen yang tepat ketika perang Asia Pasifik dimana Bangsa Jepang melawan sekutu dan membutuhkan bantuan relawan tentara cadangan, tenaga dari bangsa Indonesia, bangsa-bangsa Asia Tenggara untuk memenangkan perang ASIA PASIFIK dengan iming-iming dan berjanji akan memberikan kemerdekaan setelah Perang Asia Timur Raya berakhir. Dekolonisasi tidak terbatas pada politik saja namun dekolonisasi meliputi, Dekolononisasi Agama, Bahasa, Budaya, Ilmu Pengetahuan, Filsafat, hampir semua aspek kehidupan dunia ini terjajag oleh bangsa Eropa, Utamanya Inggris yang menganggap bahwa merkalah yang paling tinggi dan Evolusi Agama dan peradaban, yang menyebabkan muncul gerakan dekolonisasi dalam semua aspek kehidupan.
Relaciones entre inter-transdisciplinariedad y pensamiento complejo: El lenguaje como herramienta de sutura epistémica
Authors: Zarta Rojas Fabian Andrey
Published: April 2024

En el presente artículo se quieren explorar algunas cuestiones sobre las relaciones entre inter-transdisciplinariedad y pensamiento complejo, y aportar a la discusión actual sobre ellas como una herramienta para la sutura epistémica y metodológica entre las ciencias modernas. La metodología que se utilizará para desarrollar esta reflexión no puede ser otra que la combinación de varios a-métodos, o, en otras palabras, un pensamiento rizomatico como lo plantea Zarta (2022) obteniendo cierta inteligibilidad profunda a partir del uso del pensamiento complejo de Morín (2002) y de la perspectiva esquizoide de Deleuze y Guattari (2004). La herramienta articuladora inter-transdisciplinar, con todas las ventajas que permite, adquiere un papel fundamental en la discusión contemporánea dada la diferencia que se presenta entre el pensamiento complejo como método y las ciencias de la complejidad como disciplinas; esto porque los autores pretenden una división, lo cual iría en contra de los principios mismos de la complejidad.

Voltaire and the Theatre of the Eighteenth Century
Authors: Carlson Marvin A.
Published: April 2024

Born in the final years of the seventeenth century, and dying a decade before the beginning of the French Revolution, Voltaire was a quintessential figure of the eighteenth century, so much so that this era is sometimes called the Age of Voltaire. At a time when French culture dominated Europe, Voltaire dominated French culture. His influence was broad and powerful, and he made major contributions to almost every sphere of intellectual activity, including the sciences, trade and commerce, politics, and especially the arts. Despite the astonishing range of his literary activities, the theatre occupied a central position in his life from the beginning of his career to its close. His first and last literary triumphs were plays, the first written when he was only 17, the last completed when he was 84. He created a total of 56, and there was rarely a time in his life when he was not working on a theatrical script. At the end of his career, his works were produced more frequently on the French stage than those of any other serious dramatist and served as models for aspiring young playwrights throughout Europe.

Written by a leading authority on French theatre and culture in the eighteenth century, this book traces the theatrical career of Voltaire from his college days through his final works. The most influential dramatist of the period, he successfully wrote in a number of genres, including tragedy, comedy, opera, comic opera, and court spectacle. His theatrical biography involves all aspects of acting and staging in amateur and society theatre as well as on major professional stages and performances at court. His extended visits to England and Germany are covered in chapters that also provide an introduction to the theatre in those countries, and his international interests and correspondence provide insights into the eighteenth century theatre in places such as Italy, Russia, and Denmark. Due to his literally life-long concern with the theatre, his dominance in this art, and his reputation and involvement with the theatre outside France, Voltaire's theatrical biography is also in large measure a chronicle of the European stage of the eighteenth century.

Policing in America
Authors: Steverson Leonard A.
Published: April 2024

This book maps the development of modern policing both theory and practice from humans' first efforts at social control, through the British roots of modern policing, to the unique institution of American policing today.

How Americans view police has varied dramatically through history. In 1856, New York police opposed wearing uniforms because they felt it represented a militaristic and nondemocratic type of organization. Today, our police model themselves on the military and use military tactics in the "war" on drugs.

Policing in America: A Reference Handbook chronicles our changing ideas and methods of social control, beginning with the first recorded instances. It traces the trends that have shaped America's unique policing system and our fascination with police. It also examines the hot-button issues that concern police scholars today such as the nature of the police subculture and police corruption and details the trends and issues that will shape the future of policing. An essential reference for those interested in and affected by the American system of policing, which impacts us all.

Authors:   , Mukembo Alex
Published: March 2024

Background The COVID-19 pandemic continues to adversely affect the population with over 233 million infections and over 4 million deaths. COVID-19 resulted in the closure of schools and education institutes in countries including Uganda. Several COVID-19 vaccines have been developed, however uptake and hesitancy remain big challenges. With the reopening of schools and education institutes tagged to total vaccination of teachers, understanding key determinants for uptake of COVID-19 uptake in teachers may help to develop strategies for improving vaccination programs. This study assessed determinants of COVID-19 vaccine uptake among teachers in Uganda. Methods A cross-sectional study was conducted using a barrier analysis approach targeting teachers from both the private and public sectors in 5 districts across the regions of the country. 448 teachers (224 vaccinated and 224 non-vaccinated) were sampled using a multistage approach. Each sampled vaccinated teacher was matched with a non-vaccinated teacher from the same community using a snowball approach. Sampled teachers were interviewed by trained research assistants using structured electronic questionnaires from May –June2021. Collected data was downloaded into Excel then cleaned before being exported to stata version 15 for analysis. At bivariate level, factors were considered significant at p<0.05 Results Factors that were positively associated with uptake of covid-19 vaccine were older age, easy access to vaccination site, perceived increased risk of contracting COVID-19, belief that COVID-19 vaccine can protect against COVID-19 and trust in the vaccine. Factors that were negatively associated with uptake of COVID-19 vaccines were, lack of vaccines , long distances from vaccination site, perceived severity of side effects and perception that few people contracted COVID-19 in the community. Conclusion- Increasing access to vaccines through the creation of more vaccination sites, sensitization of safety of Covid vaccines, and risk of contracting Covid by teachers are critical to increasing COVID-19 vaccination rates among teachers.

The results show that the platform most widely used for telemedicine services during the COVID-19 pandemic was platform H by 25 people. The average satisfaction of telemedicine users during self-isolation tends to be high, namely 3.8 with the lowest value being 2.3 (SD=0.534). Service quality and user satisfaction are all positively correlated with weak to strong correlation levels, namely responsiveness (r=0.306), service reliability (r=0.598), information quality (r=0.490), empathy (r=0.509), ease of service (r=0.633), perceived usefulness (r=0.486). The quality improvement factor is based on high satisfaction in easier appointment registration, savings in out-of-pocket costs for travel and queuing time at health services. However, holistic health and regulatory services are needed to address user data security threats.
A comprehensive comparison of the two MPPT techniques (P&O, SMC) for photovoltaic systems
Authors: TAHIRI FADILA , HARROUZ Abdelkader , BOSTANCI Gazi Erkan
Published: April 2024

This paper aims to study the behavior of different maximum power point tracking (MPPT) techniques applied to PV systems. In this work, we evaluate and compare perturbation and observation (P&O) and sliding mode control (SMC) techniques. a DC/DC boost converter is used between the PV system and load to transfer the maximum possible power. the conventional MPPT methods Perturb and Observe (P&O) cannot detect and track the highest peak. Thus, this causes an important loss of power, so a technique is suggested sliding mode control, which offers many benefits such as durability against parameter changes, minimal current output distortion, and excellent reference tracking. The simulation results shown in MATLAB confirm that the sliding mode control method allows to have a faster response compared to P&O, to reduce the steady-state fluctuations and better track the maximum power point with fewer power losses.

Objective. To form a clinical and functional characterization of patients with chronic dizziness.

   Materials and methods. A single one-stage cohort study of 32 patients with chronic dizziness (CD), among them 26 women and 6 men, mean age - 49 [36.5; 51.5] years, was conducted. Patients were examined by objective neurologic examination, laboratory (general and biochemical blood tests) and instrumental (radiography, magnetic resonance imaging (MRI), ultrasound) methods were used during the study. Barany’s test was also performed, and neuropsychological testing was performed. The data were processed using descriptive statistical methods of the application package “Statistica”, 10.0.

   Results. During the examination, patients complained of dizziness (100 %) and shakiness when walking (84 %), provoked mainly by intermittent visual stimuli (31 % each). Subjective neurological deficit in patients with CD was caused by kinesthetic sensations of instability (34 %), accompanied by decreased attention and memory (28 %). Objectively, the phase of optokinetic nystagmus in Barany’s test lengthened in the studied group - 190 [170; 225] s and the time of balance retention in Romberg’s pose decreased - 3 [2; 5] s. CD patients were characterized by high personality anxiety - 53 [44; 53] points and autonomic imbalance according to the questionnaire of A.M. Vein - 42 [40; 44] points. We did not reveal a connection of CD with structural anomalies, pathology of brachiocephalic vessels.

   Conclusion. The clinical and functional status of CD patients was characterized by the absence of focal lesions of the nervous system and a small number of concomitant diseases causing vertigo. At the same time, the patients’ subjective sensations underlying the perception of non-existent stimuli led to impaired maintenance of vertical body position and, in turn, formed an anxiety disorder.

Objective. To study the effect of drugs regulating acute immune responses on liver in septic processes.

   Materials and methods. The study was conducted on 39 male white rats weighing 250-400 g. The animals were initiated septic process development by intraperitoneal injection of Klebsiella pneumoniae culture suspension with simultaneous intravenous injection of polyvinylpyrrolidone (PVP) and gadolinium in the volume of 0.6 ml. On the 14th day the animals were removed from the experiment by decapitation under light ether anesthesia, blood and liver were taken for biochemical and histological studies.

   Results. When analyzing the morphometric parameters of liver preparations, an increase in the number of nuclei and a slight increase in the area of nuclei in three experimental groups was established by 1,2 times (p < 0,05) compared to the control group, which reflects the ongoing processes of hepatocyte regeneration due to possible mechanisms, namely hypertrophy nuclei and proliferation with both PVP and gadolinium in systemic inflammatory response and sepsis. Moreover, the use of PVP and gadolinium led to a decrease in the likelihood of perinuclear edema, protein degeneration and large droplet vacuolization (p < 0,05). When using gadolinium, the lumen diameter of the sinusoids was the largest and amounted to 4,47; 3,22-5,63 µm (p<0,05), and in septic shock it did not differ from the group where PVP was used (p > 0,05). Of the laboratory parameters of surviving individuals, the lowest ALaT level was noted in the gadolinium experimental group – 53,7; 51,8-55,1 U/L (p<0,05), while the lowest urea level was observed when using PVP (5,0; 4,99-5,15 mmol/l) (p < 0,05) as part of a systemic inflammatory response.

   Conclusion. Gadolinium and PVP have a positive effect on the detoxification function of liver. Moreover, the effect of PVP on the morphology and function of the liver differs at the stages of septic process.

The article describes a clinical case of atypical aggressive progression of mycosis-associated hyperplasia of the lingual tonsil with proliferative changes in the pharyngeal and palatine tonsils. The features of etiology, pathogenesis, diagnostic challenges, and an effective treatment method for this pathology are presented. Based on clinical experience, it is important to note that the prevalence of lingual tonsil diseases is significantly higher than their detectability. This is attributed to its anatomical-topographical and morphological characteristics of location and structure, as well as the relative difficulty of examination (due to a high pharyngeal reflex), the need for the specialist physician to master hypopharyngoscopy techniques, and the lack of a clear algorithm for clinical examination of such patients.

Female breast cancer is known to be one of the leading causes of death in Senegal. In Senegal, the absence of a national cancer control program, the lack of specialized infrastructure and qualified human resources and the exorbitant cost of care have contributed to the extensive use of traditional medecine, particularly in rural areas. This study aims to inventory the medicinal plants used by these healers and to assess the cytotoxic and antioxidant activities of the most widely used one. Data on healers and their use practices and information on plants were collected through the administration of a structured questionnaire. Based on their citation frequencies during the survey, Antiaris Africana Engler, Hymenocardia Acida Tul. and Halouf Halal (local name) were selected for chemical and biological studies. Their hydroalcoholic extracts were analyzed in terms of antioxidant capacity and cytotoxic effects, again, in the human cancer cell line. The study revealed a total of 65 medicinal plants belonging to 35 different families. The plant parts used by traditional healers are leaves (63.89%), roots (11.11%), bark (15.28%), fruits (2.78%), and others (6.94%). Generally, herbal medicine is prepared as a powder and mixed with water by maceration (55.38%) and administered orally. A. Africana ranked first with a citation frequency of 5.7% and its hydroalcoholic extract had the highest antioxidant activity in TEAC (6533.64±7 μmol ET/g dry plant) and in ORAC (3745.17±4.8 μmol ET/g dry plant) followed by H. Acida in TEAC (3115.6±145 μmol ET/g dry plant) and in ORAC (4105.29±872 μmol ET/g dry plant). The hydroalcoholic extract of A. Africana exhibited the highest cytotoxic activity in MCF-7 (Human mammary) and THP-1 (Human acute monocytic leukemia cell line) but had low activity against HTC-116 (Human carcinoma colorectal) and A-375 (Human skin malignant melanoma). The percentages of proapoptotic cells were, respectively, 68.85±6.22, 58.1±1.90 and 48.58±1.4%. These results provide scientific support for the traditional use of medicinal plants in cancer treatment and constitute a database for biological screening to isolate cytotoxic plant-based molecules.

The focus of the current study was to investigate the presence of selected trace metals (Pb, Cd, Mn, Ni, and Cu) and to determine the major cation and anion levels in Nyamyumba and Bugarama hot springs in the Western Province of Rwanda. The trace metals were determined using micro plasma atomic emission spectroscopy. The mean Cu concentrations in Nyamyumba and Bugarama were found to be 0.1 mg/L and were within the permissible limits of the World Health Organization (WHO) for potable water. Similarly, Mn concentrations were within acceptable WHO limits with mean concentrations being 0.04±0.02 and 0.11±0.03 mg/L in Nyamyumba and Bugarama, respectively. The lead concentration was found to be above the WHO limits with mean results of 0.01±0.001 and 0.013±0.01 mg/L in Nyamyumba and Bugarama, respectively. The mean concentration of cadmium was 0.01 mg/L in both sampling sites, which is observed to be above the allowed WHO limit. Nickel, on the other hand, was found to be below the detection limit. The fluoride concentration was determined using the SPADNS Ultra Violet Spectroscopic (UV-VIS) method and its mean levels were found to be 1.07±0.05 and 0.85±0.07 mg/L in Nyamyumba and Bugarama, correspondingly, which is within the acceptable limit of the WHO. Due to the potential pollution trends identified in this study, it is recommended that biosorption remediation techniques be applied for potable and therapeutic water usage to reduce the levels of Pb and Cd, which can have serious etiological risks to both flora and fauna due to possible trace metal bioaccumulation.

Theoretical calculation of 4-((4-aminophenyl)diazenyl)-2-((2-phenylhydrazono)methyl) phenol (1) and N-(4-((4-hydroxy-3-((2-phenylhydrazono)methyl)phenyl)diazenyl)phenyl) acetamide (2) was studied by DFT/B3LYP/6-311+G(d,p) basis set. The calculated values of geometric structural parameters, Fourier transform infrared spectral data, highest occupied molecular orbital and lowest unoccupied molecular orbital, natural bond orbital, nucleus-independent chemical shifts, Fukui function, polarizability, hyperpolarizability, and UV data of compounds 1 and 2 clearly indicate that substitution of the amino group alters the physical properties of compound 2. The nucleus-independent chemical shift values of the amino-substituted phenyl ring reduces the aromatic character due to the lone pair electron on nitrogen involved in inductive and conjunction effects, as well as due to OH, NH2 and OH, NHCOCH3 in compounds 1 and 2, respectively. The effect of the solvent on different parameters was studied, and it was found that increasing the dielectric constant increased the parameter studied. The stability and planarity of the molecule’s effects on dipole moment, energy, polarizability, and hyperpolarizability were studied extensively.
