This observation aims to determine the waste in the slaughterhouse and utilize solid waste into handicrafts. In this broiler business, the concept of environmental efficiency has not been fully implemented. There is still a lot of waste that is thrown away without thinking about the impact it will have. Waste that is not recycled again will have an impact on water, air and soil pollution. The waste found in the poultry business includes water waste and solid waste. Waste generated from wastewater is water from washing chickens. Meanwhile, the solid waste produced is dead poultry, chicken internal organs, chicken feathers thrown into the river, and chicken manure. The implementation in this observation is by conducting a literature study, conducting direct observations, taking samples or materials to be processed, educating owners and employees, processing or recycling solid waste that will be recycled into handicrafts. There must be awareness from business actors and employees to apply the principles of green manufacturing and the importance of health and the impact it has on the surrounding community and implement a recycling process on solid waste found or utilize effective process technology that allows the production of raw materials for other sectors while reducing amount of waste generated.

Authors: Lambada Puneeth Raj , Wang Xin
Published: June 2024

By elevating the operational frequency, there exists the potential to diminish the transformer’s size and weight while simultaneously augmenting its power density and efficiency. Nonetheless, this approach is not without its challenges and practical limitations. This research delves into the optimal design considerations for core-type medium frequency transformers. In comparison to their shell-type counterparts, core-type transformers offer significant advantages, including ease of repair and maintenance, more efficient cooling, and superior suitability for high-voltage applications in transmission and distribution transformers. Additionally, we conducted a comparative analysis between copper wire split winding and Litz-wire winding for core-type transformer applications. The utilization of geometric programming facilitates the derivation of an efficient and dependable global optimal solution for the design of solid-state core-type transformers.

Published: June 2024

The use of biodiesel for common rail direct injection (CRDI) diesel engines is very difficult, because its viscosity affects on CRDI systems leading to the high engine knock. Thus, the main aim of the research is to study the performance and emission characteristics of a CRDI diesel engine at a constant speed of 1,500 rpm and different loads, operated with diesel mixed with palm-oil biodiesel at 20% (B20) combined with adding alcohols (5% of ethyl acetate and bioethanol increased from 5 to 20%). Results of exhaust emissions and performance parameters from using B20-bioethanol-ethyl acetate blends compared with fuel baselines (regular diesel and B20) were changed. The B20-bioethanol-ethyl acetate blends increased the releases of carbon dioxide (CO2) and nitric oxide (NO) but the reduction of carbon monoxide (CO) and black smoke (BS) compared with fuel baselines. Meanwhile, performance parameters from using these fuel blends were different. Outstandingly, B20 mixed with 5% of bioethanol and 5% of ethyl acetate had the highest engine performance and the lowest CO and BS emissions, but it released the CO2 and NO levels higher than fuel baselines.

Published: June 2024

Interdisciplinarity constitutes one of the main drivers for the development of scientific knowledge as it contributes instimulating scientific research from different perspectives and methodologies and inreducing the isolation between disciplines. Although interdisciplinarity has become a common trend in scientific and academic circles of universities and research centers in recent years, the concept of interdisciplinarity remains largely controversial. The concept of interdisciplinarity is still fraught with confusion and ambiguity on many levels, including terminology, the model through which interdisciplinarity can be applied, and the methods or criteria through which interdisciplinarity can be detected. In this context, this research engages with the interdisciplinary studies through three main questions closely related to interdisciplinarity. The first question delves into the nature of interdisciplinarity research, scrutinizing prevalent ideas surrounding it. The second question explores proposed models for interdisciplinary research, their criteria, and examines whether a normative interdisciplinary model emerges from the literature. Whereas, the third question focuses on difficulties and opportunities facing interdisciplinary research in academic environments. In an attempt to answer these questions, several researchers from different disciplines participated in writing this research paper, where they engaged critically with the prevailing literature on interdisciplinarity, and presented a comprehensive theoretical review based on three levels of analysis.

Kolmogorov-Arnold Networks: Key Developments and Uses
Authors: Hadj Kilani Bochra
Published: June 2024

Kolmogorov-Arnold Networks (KANs) have emerged as a promising advancement in the field of neural networks, offering enhanced interpretability, efficiency, and adaptability. This literature review explores various applications and developments of KANs. Temporal KANs (TKANs) combine the strengths of Recurrent Neural Networks (RNNs) and KANs for improved multi-step time series forecasting. DeepOKAN employs Gaussian radial basis functions (RBFs) in lieu of B-splines for computational mechanics, resulting in a notable acceleration and enhancement in efficiency. Wav-KANs utilize wavelet functions for data analysis, offering a balance between detail and overview. KANs have also been utilized in image classification, integrating with pre-trained Convolutional Neural Network (CNN) models for remote sensing scene classification tasks. The Variational Quantum Kolmogorov-Arnold Network (VQKAN) implements a quantum version of KAN on a quantum circuit, optimizing synaptic connection weights for improved efficiency. KANs have also been applied for Explainable Natural Language Processing (NLP), forming continuous word embeddings based on the meaning profiles of words. The review also mentions UKAN and IKAN, These advances underscore the versatility and potential of KANs in enhancing various machine learning applications. Future research will likely concentrate on further refinement of these architectures and exploring their suitability to diverse datasets and tasks.
Candida and Long Covid: Mannan Not from Heaven
Authors: Chambers Patrick
Published: June 2024

The pandemic has supercharged growing awareness of the gut microbiome as a critical determinant of human health. “Long haulers” share microbiomes similar to those seen in myalgic encephalomyelitis/chronic fatigue syndrome and fibromyalgia, all frequently associated with Candida overgrowth (CO). Candida can synthesize its own IDO, altering tryptophan metabolism (ATM). Zonulin, a circulating protein that increases intestinal and endothelial permeability, has emerged as a central player. Candida hyphal walls express proteins analogous to gliadin/gluten, e.g., celiac disease (CeD), and mannans, e.g., Crohn’s disease (CrD), that may trigger antigliadin and anti-Gq coupled GPCR auto-antibodies linked to their lectin binding domain respectively. Hyphal mannan may induce auto-antibodies to AT1Rs, α1-ARs, mAChRs, and β2-ARs, prominent in LC, and regulate T cell receptors (TCRs) and regulatory B cell function, compromised in not only LC (vitiligo, psoriasis, alopecia) but also SLE, RA, and many other autoimmune diseases. All are Gq coupled GPCRs. The spike protein S on SARS CoV2 can attach to both the ACE2 receptor (required for tryptophan absorption) and Toll-like receptor4 (TLR4) bearing endothelial cells and enterocytes. Spike protein S is persistent in most with LC and, as a ligand for TLR4, can also activate zonulin. S can also activate the NLRP3 inflammasome, as can candidalysin. This inflammasome is directly connected to dementia, cancer, autoimmunity and obesity. Candidalysin causes hypercitrullination, instrumental in creating ACPAs (anti-citrullinated peptide antibodies) linked to LC, MCAS (mast cell activation syndrome), HSD (hypermobility spectrum disorder), and APS (antiphospholipid syndrome). A hypothetical pathophysiologic model is proposed implicating pre-existing CO, aggravated by Covid-19, in not only the genesis of LC but also that of autoimmune disease, dementia, cancer, many chronic diseases, and aging.

Authors: Łanowy Patrycja , Sobala-Szczygieł Barbara , Żmudka Karol Jerzy , Włosowicz Aleksandra , Jaroszewicz Jerzy
Published: June 2024

Actinomycosis is a very rare, infectious disease, which is especially difficult to diagnose due to non-specific symptoms and the ability to emulate neoplasms or inflammatory changes. Due to those facts, it is often misdiagnosed or diagnosed too late to be successfully treated.
This article presents the case of 31-year-old Caucasian female with recurrent upper respiratory tract infections and tonsillitis as the potential risk factors of actinomycosis. Upon examination of material collected through the course of tonsillectomy, the patient was diagnosed with actinomycosis of the left palatine tonsil. Despite the introduction of antibiotic therapy, initial progression was noted with the appearance of numerous, hypodense changes in the liver and the spleen, which regressed during further antibiotic treatment.
According to our team's knowledge, this is the first described case of a patient with actinomycosis occurring simultaneously in the cervico-facial and abdominal area. The unusual localization and potential dissemination of actinomycosis should be considered in clinical practice.

Published: June 2024

Kazimierz Funk, born on February 23, 1884, in Warsaw, demonstrated an early inclination toward the field of human physiology. He charted his scientific trajectory within esteemed European scientific institutions, commencing at the age of 16 in Geneva, where he pursued studies in natural sciences. Subsequently, he continued his academic endeavors in Bern, culminating in the attainment of his doctorate in 1904. Following this, Funk relocated to Paris and secured a position at the Pasteur Institute. In France, his research concentrated on elucidating the role of trace elements in the human body. In 1906 he transitioned to Berlin, collaborating with Hermann Fisher (1852-1919) to investigate proteins and cancer processes. In 1910, Funk ventured to London, joining the Lister Institute, where he initiated research on beriberi disease. His investigations led to the isolation of a substance pivotal in treating the ailment, which he termed "vitamin" (derived from 'vita' meaning life and 'amine' indicating a nitrogen-containing compound). Despite four nominations for the Nobel Prize (in 1914, 1925, 1926, and 1946), Kazimierz Funk didn’t receive the prestigious accolade. In 1925, at the urging of Dr. Ludwik Rajchman (1881-1965), the director of the National Institute of Hygiene, Funk assumed the directorship of the Biochemistry and Hygiene of Nutrition Branch at the National School of Hygiene. Under Funk's guidance, Poland became the third European country to produce insulin. Kazimierz Funk passed away on November 19, 1967, in New York City, at the age of 83. His significant contributions to the fields of biochemistry and nutrition endure as a testament to his enduring impact on scientific understanding. This proposal aims to condense and emphasise Kazimierz Funk's diverse scientific interests and the various scientific teams and sites he collaborated with, which ultimately led to his groundbreaking discover.

Published: June 2024

A múlt század 60-as éveitől mind a polgári, mind a katonai repülésben az egyszerű, egyáramú sugárhajtóműveket felváltották a kétáramú hajtóművek. Először a kis kétáramúsági fokú hajtóművek jelentek meg, majd a kétáramúsági fok folyamatosan növekedett a kereskedelmi repülőgépek kétáramú hajtóműveinél. Manapság a kis kétáramúsági fokú hajtóművek jellemzően a többfeladatú harcászati repülőgépek erőforrását képezik. Maga a hajtómű kialakítása jelentősen nem változott évtizedek óta. Ehhez képest jelenthet új szintet és igazi minőségi ugrást az adaptív hajtómű-technológia. A cikkben ezt a fejlesztési folyamatot, illetve a várt előnyöket mutatom be.

DEVELOPMENT OF A SOFTWARE SYSTEM FOR SEARCHING FOR LOST ITEMS
Authors: Solovei I. , Vorochek O.
Published: June 2024

The article presents an approach to developing a software system to facilitate the efficient search for lost items. As part of the study, the authors designed an integrated system that includes server, web, and mobile versions, which provides broad opportunities for identifying and returning lost property.
In large urban agglomerations, the loss of personal items becomes a common problem. Existing solutions are often limited to preventive measures and do not provide sufficient support after the item’s loss. The lack of an effective feedback and identification system complicates the lost property search process.
The developed system uses modern technologies such as Django for the backend, JavaScript for the web interface, and Flutter for creating cross-platform mobile applications. This approach makes it possible to expand the list of system users to the maximum extent. Django, a capable web framework, facilitates reliable data management and integration with various interfaces.
The study involved the development of a database to provide storage and processing of all the necessary information. Using REST API ensured efficient interaction between the system’s server, web, and mobile parts. This approach allows different system components to exchange data in a unified format.
The system lets users register individuals and legal entities, which makes it possible to use it in a wide range of public spaces. It helps to effectively search for and return lost items on the street and in public places, including restaurants, theatres, and transport hubs where lost items often occur.
The software system created in this study addresses the critical problem of losing personal items. Widespread use of this system across various sectors could dramatically improve managing lost and found operations, turning a typically disorganised and ineffective process into an efficient, technology-driven one. The system’s implementation has the potential to significantly reduce the time and resources spent on searching for lost property and increase the productivity of lost property offices.

The Program for International Students Assessment (PISA) is a triennial survey of 15-year-old students worldwide. The assessment focuses on core school subjects, namely science, reading, and mathematics. The 2015 PISA survey covers 70 countries, including Indonesia. Indonesia has been participating in the PISA survey since 2000. This article aims to map Indonesia's position towards the PISA participating countries in 2015, which amounted to 72 countries. The analysis used is Multi-Dimensional Scaling (MDS) analysis. The mapping of this position is based on the average value of science, reading, and mathematics. From the analysis results, it is found that Indonesia's position is grouped against the 70 participating countries. From this grouping, it can be seen what Indonesia has taken follow-up actions to improve the quality of education in Indonesia, especially in science, reading, and mathematics subjects.

Unit Commitment (UC) discusses the optimized generation resources (to turn on economical generators and turn off expensive generators),which are subjected to satisfy all the operational constraints. The operational constraints such as load balancing, security maximization, minimum up and down time, spinning reserve, and ramp up and down constraints are difficult to satisfy. Although, UC is a cost minimization problem that is realized by committing less expensive units while satisfying the corresponding constraints, and dispatching the committed units economically. The UC problem is an np-hard Mixed Integer Nonlinear Problem (MINLP). Therefore, in this paper, hybrid EA based on a Genetic Algorithm (GA) has been applied to find the optimal solution to the UC problem. Moreover, during the search process, it is very difficult to discard infeasible solutions in EAs. Hence, the Genetic Algorithm (GA) is integrated with the feasibility rule constraint handling technique to emphasize feasible solutions. IEEE RTS Eleven Thermal Generator Standard Test system is used to validate the performance of proposed methods. For the validation and the superiority of the proposed algorithm, simulation results are compared with the classical Lagrangian Relaxation (LR) methods. Results show that the proposed method can find the global optimal solution to the UC problem which is subjected to satisfy all the operational constraints.

Ante la necesidad académica de plantear alternativas didácticas para afrontar la solución de proyectos arquitectónicos que detonen propuestas amigables con el medio ambiente, se presenta la arquitectura circular como una respuesta del quehacer arquitectónico para inhibir el impacto ecológico que se tiene en las edificaciones, en los contextos locales. La arquitectura circular responde a los desafíos en los proyectos arquitectónicos ya que, además del impacto ecológico en los productos, se puede dialogar con su metodología como una serie de estadios etápicos en la didáctica del aprendizaje basada en proyectos. Por ello, el objetivo de este trabajo es demostrar que cada etapa de un modelo didáctico se puede robustecer mediante un diálogo disciplinar para potenciar la arquitectura circular en el aprendizaje. Por ende, se presenta la manera en que se incrementa la etapa de argumentación arquitectónica en el modelo de didáctica basada en proyectos, mediante un diálogo disciplinar con la biofilia; esto genera herramientas al estudiante y justifica, de mejor manera, sus proyectos, mediante la construcción de una nueva tendencia como la bioarquitectura circular. Esta sirve para robustecer una etapa del modelo del proyecto basado en la arquitectura circular.Palabras clave: modelo de enseñanza, arquitectura circular, biofilia, proyecto arquitectónico, bio-arquitectura.
AbstractGiven the academic need to propose didactic alternatives to address the solution of architectural projects that trigger environmentally friendly proposals, circular architecture is presented as a response to architectural work to inhibit the ecological impact that buildings have in local contexts. Circular architecture responds to the challenges in architectural projects since, in addition to the ecological impact on products, its methodology can be discussed as a series of stages in the didactics of project-based learning. Therefore, this paper aims to demonstrate that each stage of a didactic model can be strengthened through disciplinary dialogue to enhance circular architecture in learning. Consequently, how the architectural argumentation is increased inthe project-based didactics model is presented through a disciplinary dialogue with biophilia; this generates tools for students and better justifies their projects by constructing a new trend, such as circular bioarchitecture. This strengthens a stage of the project model based on circular architecture.Keywords: teaching model, circular architecture, biophilia, architectural project, bio-architecture.
