Authors: Mahadevan G. , Ramasamy Nallamuthu , Jayaseelan V. , Mohamed-Bak K.
Published: January 2024

The water sorption characteristics of Kevlar fiber–reinforced epoxy composites were studied by immersion in water at 80 degrees Celsius. The hydrothermal aging process was conducted on treated and untreated Kevlar/epoxy composites; also, the composite was evaluated by the three-point bending test. The phosphoric acid (PA) pretreated with epichlorohydrin (ECH) was used for the surface modification of Kevlar. In the case of chemically modified fiber composites, water uptake was found to be dependent on the chemical treatment done on the fiber surface. The lowest water uptake was observed for composites treated with PA with ECH. The effect of thermal aging on the flexural strength of the treated Kevlar composite was 20.42% higher than the untreated composite. Consequently, the flexural modulus was 13.9% higher than the untreated Kevlar composite. Moreover, the water diffusion coefficient of treated composite 23.19% higher with untreated composite. It was concluded that fiber/matrix degradation time at the interface region was increased in the case of treated composite

Authors: ROA KAROL LIZETH , Trejo Zárraga Fernando , Castro Silva Hugo Fernando
Published: January 2024

This paper reviews the application of a geopolymer composite using an easy synthesis route based on the activation of metakaolin (MK) as aluminosilicate source, and activated carbon (AC) as a porous agent, to improve porosity and adsorption capacity. The main goal of this work is to evaluate the ability of the obtained geopolymer to remove Hg2+ from aqueous solutions, for comparison purposes a geopolymer sample was fully synthesized with metakaolin aluminosilicates. Samples were investigated by X-ray fluorescence (XRF), Fourier transformation infrared spectroscopy (FTIR), compressive strength test, and scanning electron microscopy (SEM). The respective removal of Hg2+ from aqueous solutions was quantified using an inductively coupled plasma optical emission spectroscopy (ICP-OES). The pH of the solution affected significantly the adsorption of Hg2+ ions onto the geopolymer surface. The maximum removal efficiency of the composite was 87.6 % at room temperature and pH 5. These results suggest the use of geopolymer with activated carbon as a successfully alternative adsorbent of Hg2+ ions from water.

Published: January 2024

The complex environment of the hospital and the critical operations practiced in the medical departments, such as the sterili zation unit, require implementing risk assessment plans as fundamental support for effective management. The Failure Modes Analysis and Effects (FMEA) method is one of the popular methods used to perform the risk assessment process. Fuzzy logic and machine learning techniques provide robust devices that improve the efficiency of several risk assessment methods, such as FMEA. Hence, this study aims to enhance the efficiency of risk assessment in hospital sterilization units using an intelligent model based on revised FMEA, an improved FMEA adaptable to the studied system, fuzzy inference system, Support Vector Machine (SVM), and K-Nearest Neighbors (KNN) techniques. An interesting application of the model in the central sterilization unit of the largest university hospital is presented. The performance of the proposed model is evaluated at the end to prove its efficiency.
New modified Bat algorithm for blind speech enhancement in time domain
Authors: Fisli Sofiane , Djendi Mohamed
Published: January 2024

We address the speech enhancement problem for dual convolutif mixed channel by viewing it in a blind separation sources setting. One widely used technique to separate mixed signals is to apply adaptive filtering, the challenge is to identify an unknown finite impulse response. traditionally we apply a gradient-based algorithm to adapt filter coefficients. However, such algorithm often suffers from premature convergence ,when using large filters and non-stationary inputs ,  leading to the so-called local minimum problem , which affects the quality of  enhanced signals significatively .one alternative to overcome this problem is to apply a population-based metaheuristic algorithms in which filter coefficients are adapted iteratively  by minimizing a cost function .But even with this metaheuristic based solution, local minimum problem at large filters still exists. In order to avoid local minima and improve the chance to reach the global solution, we propose in this paper, a novel algorithm called a modified bat algorithm to render the search process efficiently by enhancing its capability of exploration and exploitation. Several experiments under different noise types are carried out using our proposed modified bat algorithm in comparison with some of the popular state-of-the-art algorithms. The enhanced signals obtained by each algorithm at the separation process outputs, show good behavior and superiority of our proposed algorithm. In terms of system misalignment, as well as a segmental signal-to-noise ratio.
Water transparency analysis in fish farming environment through unmanned aerial vehicles
Authors: Bartz R. L. , Feiden A.
Published: January 2024

Since water transparency in a fish farming environment is an important parameter in fish development, and it is important that the fish farmers be attentive to the control of the same. However, the process of measuring water transparency in fish ponds is usually done manually, which makes it expensive and inefficient. In order to solve this problem, a prototype was developed containing 2 optical sensors capable of capturing images in the NIR, R, G and B bands, connected to a microcomputer coupled to a Remotely Piloted Aircraft (RPAS), in order to capture aerial images of water and estimate water transparency through an image processing algorithm. The prototype was tested by an experiment conducted in a rural estate of the city of Toledo – PR, where 66 images were captured on a conical target, constructed to serve as a reflective reference for the images, comparing the results with the measurements collected by a Secchi disk, using Pearson's correlation analysis. The results showed a strong correlation (r = 0.98) in the estimates made by the NIR band processing, followed by the RGB, R, G and B bands. The developed system proved to be effective in data collection, processing and analysis, optimizing the fish farming management.

Authors: Mittal M. , Phutela K.
Published: January 2024

The primary objective of this work includes modeling and optimization of the mechanical properties of natural fiber biocomposites using three-factor, three-level Box-Behnken design (BBD). In this context, the effect of three independent performance parameters; pineapple leaf fiber (PALF) length, fiber content, and polyethylene-grafted-maleic anhydride (MAPE) compatibilizer load have been investigated on the mechanical properties of PALF/HDPE/MAPE biocomposite. The sequential model sum of squares, lack of fit, and normal probability plots showed a good agreement in between the experimental results and those predicted by mathematical models (95% confidence level). The optimization results obtained in Design-Expert software revealed that the most optimal value of tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength as 32.35 MPa, 1475 MPa, 49.21 MPa, 1659.04 MPa, and 58.24 J/m respectively, at fiber length of 13.67 mm, PALF content of 16.84 wt.%, and MAPE load of 2.95 wt.%. In order to verify the mathematical models, the validation tests were also performed which showed that the response surface methodology (RSM) based BBD and ANOVA tools are adequate for analytically evaluating the performance of biocomposites.

Published: January 2024

In recent years, metal nanoparticles (MNPs) have garnered interest in scientific development due to their novel properties, among which are optical, electrical, and magnetic properties, along with absorption capacity and high surface. There are currently several synthesis methods for MNPs, but many are costly and generate toxic agents as byproducts into the environment. Therefore, in this work, a green, ecological, and affordable synthesis of silver nanoparticles (AgNPs) was carried out using Porophyllum Ruderale (P. Ruderale). The AgNPs obtained were characterized by Fourier transform infrared spectroscopy (FTIR) to observe the functional groups that intervene in the synthesis. UV-Vis spectroscopy was used to study the surface plasmon band, confirming the peak absorbance wavelength at 385 nm. The morphological analysis by scanning electron morphology (SEM) showed AgNPs measuring 70–500 nm and spherical shapes. The synthesis process was optimized using two factors: temperature, reducing agent and precursor agent ratio (extract:RA) (AgNO3–PA), and an output variable, which is the particle size evaluated by SEM. The optimal temperature for AgNP formation was found to be 90 ºC; it was a key parameter to form AgNPs. The work proved AgNPs can be obtained and potentially used as biosensors, antimicrobial agents, and herbicides, among others.

In this work, aerogels were obtained by vacuum drying, an uncommon method that requires lower energy costs and creates materials with high porosity and small pore size. Starch from A98 rice was used, evaluating different concentrations (8, 10, and 12%) and retrogradation times (2, 4, and 6 days). The aerogels were characterized by analysis in a scanning electron microscope, in a Fourier transform infrared spectrophotometer and differential scanning calorimetry. Importantly, the retrogradation time showed no apparent significant changes in the formulation of the materials, and those created at a concentration of 10% presented a crystalline and amorphous reorganization. They were more homogeneous than the rest of the formulations while their pores measured 41 nm. Aerogels formulated with 8% presented higher swelling and water absorption but reduced solubility. The aerogels reported in this work show promising characteristics and the drying technique opens the doors to a more practical method that deserves further research.

Authors: Bavtar Gorkem , Cetinel Gokcen , Yavuz Cenk , Akiner Onur
Published: January 2024

Abstract: Electric and hybrid vehicles, known for their environmental benefits, also present a unique challenge because of their quiet operation. In urban settings, this lack of noise increases the potential for accidents with pedestrians who rely heavily on auditory cues. In response to this concern, Acoustic Vehicle Alerting Systems (AVAS) have been introduced and many countries, including the US and EU, have mandated the installation of Acoustic Vehicle Alerting Systems. These systems produce sounds to alert pedestrians of an approaching vehicle by increasing the audibility of electric and hybrid vehicles to ensure pedestrian safety [1]. In this paper, we dive deep into designing an effective AVAS for commercial vehicles, such as trucks and buses. Any AVAS must conform the international regulations such as the ECE-R138 regulation by the United Nations Economic Commission for Europe (UNECE) and FMVSS 141 by the National Highway Traffic Safety Administration (NHTSA), so our design adheres to guidelines set by key global bodies. This endeavour was supported by The Scientific and Technological Research Council of Türkiye. Our AVAS not only offers a variety of sound options but also includes self-diagnostic features to ensure its consistent performance. An integral part of our study was the utilization of an ASIL-B functional safety-compliant embedded MCU system to generate and manipulate psychoacoustic sounds. The regulations regarding the acoustic characteristics of AVAS sounds, such as minimum sound level, frequency spectrum, and frequency shift, have been instrumental in improving awareness of the AVAS sounds of quiet vehicles[2]. The ultimate aim is to showcase a versatile, compliant, and efficient AVAS, beneficial for the future landscape of electric and hybrid commercial vehicles

Authors: Çamlıbel Osman , Aydın Murat , Koç Enüs
Published: January 2024

Softwoods are the basic and traditional raw materials for medium-density fiberboard production. However, sustainable consumption of wood material in the production of wood-based products requires material variety. Therefore, the usability of hardwood species in the production and its effects on the board properties should be of interest. Considering this, the influence of oak utilization percentages (30 %, 50 %, 70 %, and 100 %) on the physical (density, thickness swelling-TS 2 and 24 h) and mechanical (modulus of rupture, modulus of elasticity, internal bonding, screw holding resistance, and Janka hardness) properties of medium density fiberboard was evaluated in this study. Boards were factory-made instead of laboratory-made using Quercus petraea (oak), Fagus orientalis (beech), and Pinus sylvester (Scots pine) fibers. According to the results, the modulus of rupture, modulus of elasticity, and Janka hardness values were increased when medium-density fiberboard was produced using only oak fiber. On the contrary, thickness swelling, screw-holding resistance, and internal bonding properties were decreased.

In this article, the author analyzes the acoustic-phonetic features of the consonants /b/, /d/, and /g/ of the Khalkha dialect, which is the standard dialect of the Mongolian Literary Language. On this basis, the author explains as follows: The phoneme /b/ is pronounced as the voiceless bilabial plosive [p] (as in stop [paɬ] ‘pen’) in any word position. The phoneme /d/is pronounced as the voiceless dental plosive [t] (as in stop [tawaː] ‘mountain pass’) in any word position. The voiceless velar plosive [k] (as in stop [kerəɬ] ‘light’) and the voiceless uvular plosive [q] (as in stop [qaɬoː] ‘бал’) are allophones for the phoneme /g/ as the initial consonant of a word or after [ŋ] at the beginning of noninitial syllables.

The correct spelling of any name directly depends on its origin and meaning. There are some cases where key names, such as Manchu, Hongtaiji, Jurchen, and Daiching related to the history of the Manchus are incorrectly written in Mongolian. Therefore, it is essential to introduce research on the meaning of these names. According to an International Bibliography of Manchu Studies, by 1990, 17 articles were published on the origin and meaning of the name “Manchu” (Stary 1990a: 870). The number shows us how serious the issue is. Pei Huang (1990: 280) claims that tracing the real meaning of the name Manchu is fruitless. However, it does not mean that all related studies are worthless. Оn the basis of these studies, it is possible to support some arguments, and also, one can suggest the correct spelling of these names in the Mongolian language. This article aims to suggest the Mongolian spelling of the above-mentioned names based on their available Manchu, Chinese, Jurchen, and Korean spellings in historical sources, dictionaries, and related studies.

Reducing sensitivity to initial imperfections by changing bifurcation diagrams
Authors: Manuylov Gaik A. , Kositsyn Sergey B. , Grudtsyna Irina E.
Published: January 2024

An approach to the construction of equilibrium state diagrams is presented in order to reduce the sensitivity to initial imperfections for the problem of stability for reinforced plates (transfer of the bifurcation point corresponding to the wave formation of ribs and cladding). New ratios of geometric parameters for two variants of strengthened plates have been obtained, where the first critical load of the general form of stability loss is the first by value, and the next critical load corresponds to the local form of wave formation of ribs or cladding. The finite element complex MSC PATRAN - NASTRAN was used to solve the stated above problems. Flat four-node finite elements were applied for modeling. The calculations were performed with account of geometric nonlinearity. The material was considered to be absolutely elastic. Curves of critical load sensitivity to the amplitudes of the initial imperfections were generated. The results demonstrate that transposition of bifurcation points of wave formation in the plate or ribs enabled to obtain curves with less significant decrease of critical load as compared to the initial ones. Consequently, the presented algorithm for changing the geometric parameters of reinforced plates obtained in accordance with new equilibrium state diagrams implements the possibility of rational design of the specified thin-walled systems.
Shells in the form of algebraic ruled surfaces on a rhombic base
Authors: Tupikova Evgenia M.
Published: January 2024

One of the promising objects for application in architectural and construction practice are analytically determined structural shapes in the form of thin elastic shells with a median surface in the form of algebraic ruled surfaces on a rhombic plan on the basis of various curves. In particular, this study considers three surfaces with identical framework forming lines of superellipses using framework curves that have the appearance of waterline, midships section, and main buttock lines - lines that have been initially generated and used in shipbuilding. The shapes of structures on a rhombic base were considered. The study contains geometric modeling of such structures, creation of finite element models and their computation. A comparison of the values characterizing the stress-strain state for three different shapes with the same span and lifting arm (variant designing with optimized choice) has been carried out. From the theoretical point of view, the possibility of generating three different surfaces on the same frame seems to be an interesting result. From the viewpoint of strength analysis, one of the three obtained shells was chosen as it has the most uniform stress distribution, which is the most economical in terms of material cost.

The paper presents a mathematical model of plasma transfer in an open magnetic trap using the condition of zero plasma concentration at infinity. New experimental data obtained at the SMOLA trap at the Budker Institute of Nuclear Physics SB RAS were used. Plasma confinement in the plant is carried out by transmitting a pulse from a magnetic field with helical symmetry to a rotating plasma. The mathematical model is based on a stationary plasma transfer equation in an axially symmetric formulation. The stationary equation of the transfer of matter contains second spatial derivatives. The optimal template for the approximation of the mixed derivative based on the test problem is selected. The numerical implementation of the model by the establishment method and the method of successive over-relaxation is compared.
DYNAMIC OF COMMUNITY: TERMS TA'ARUF BEFORE MARRIAGE PERSPECTIVE PROPHET'S HISTORY
Authors: Nuryanti Evi , Akmar Khurratul , Siam Khusus
Published: January 2024

This research is based on the fact that there are many prospective husband and wife pairs who do not carry out the ta'aruf process in accordance with religious law. Many of them violated several rules of the ta'aruf process itself. In addition, there are still many people who do not know and understand the meaning of ta'aruf and how the process is carried out during ta'aruf. Due to this lack of understanding, not a few parents and young people violate these rules, one of which is the interaction between men and women without a murobbi or intermediary from each potential partner. So that many young people who want to get a potential partner today are taking the wrong path, namely by dating. They mix up the term ta'aruf with dating on the grounds that they can get to know each other's personalities. It is very vulnerable to immoral acts. The purpose of this study is to find out more about how the ta'aruf process is and how the concept of ta'aruf is in the Prophet's Hadith. This research is a library research, namely by collecting, reading and reviewing various materials from several sources related to the problems studied. The source on which this research is based is from the Hadith of the Prophet, wherein the Hadith refers to the procedures that must be carried out in the process of ta'aruf. This article discusses the study of family law in Islam, more specifically regarding ta'aruf according to the perspective of the hadith of the Prophet Muhammad SAW. Family law is the law that regulates relations arising from family relationships. In the discussion it is stated that ta'aruf is one of the processes recommended by the Prophet before establishing a family relationship (marriage). Ta'aruf itself means to know more closely, in the sense that it is not just a name but also related to the vision and mission of the marriage of the prospective partner. This is the goal so that the family relationship that is lived can become a family that is sakinah, mawadah, warahmah.
ANALYSIS TA'ZIR PUNISHMENT AND ISTINBATH LEGAL METHOD IMAM MALIK'S PERSPECTIVE
Authors: Sufrizal Sufrizal , Abdillah Muhammad Alwin , Anzaikhan M.
Published: January 2024

This study discusses the human ta'zir perspective of Imam Malik. Imam Malik argues that there is no minimum and maximum limit for uqubah / ta'zir punishment. It is well known in the Maliki madzhab, especially Imam Malik, that ta'zir punishment can exceed the limits of had punishment in some conditions and situations. Imam Malik once flogged a man who was found with a boy 400 lashes. Imam Malik's opinion is based on the actions of Umar bin Khatab r.a. where he flogged a man who faked Umar bin Khatab's ring to trick the baitul mal guard, with the aim of taking some of the baitul mal treasures. Caliph Umar at that time whipped him 100 times on the first, second and third day. If accumulated, umar bin khattab whipped the man 300 lashes. If we look at the istinbath method / method of determining the law used by Imam Malik r.a on this issue is to take the fatawa of the companions / mauquf hadith as a conceptual basis for determining the law and leave the Prophet's hadith which expressly prohibits the implementation of the ta'zir punishment beyond ten lashes. It is clearly seen in this problem that the characteristics of Imam Malik and his followers are very respectful of the words and actions of the companions even though at first glance they contradict the text.
RICE FIELDS MANAGEMENT AGREEMENT SYSTEM IN ACEH BESAR (Study of Engagement Patterns and Sharing of Harvest Results)
Authors: Jamal Irwansyah Muhammad , Zubaidi Zaiyad
Published: January 2024

Rice field management, which is carried out by involving the people of Aceh Besar based on the norms of Islamic law and customary law, is applied from the beginning of the determination of the engagement to the capital of the harvest. Community practice describes the procedure for contracting and distributing crops in various forms. However, all farmers do it by mutual consent. This phenomenon is the focus of study in this paper. By basing on the method of discriptive analysis, the answers will be found, including: 1) the formation of contracts is carried out orally. The form of an oral contract is based on several things, namely the relationship between the parties; In general, the parties come from relatives or close family. Because of this relationship, they believe there will be no default made by the parties. In addition, there are two ways to start involvement in rice field management; First, half of the respondents agreed that capital is borne by rice field owners (this model is called muzara'ah), and half said capital is borne by farmers (this model is called mukhabarah). 2) the distribution of crops is carried out in the following way; 1) Mawah, which is divided equally between rice field owners and farmers. There are 3 people (20%); 2) Bulung 3, which is 2 parts for farmers, 1 part for rice field owners = 5 people (33.3%); 3) Bulung 4, which is 3 parts for farmers, 1 part for rice field owners = 4 people (26.6%); 4) Bulung 5, which is 3 parts for farmers, 2 parts for rice field owners =3 (20.1%). In addition to the three things already mentioned, the parties also agreed on the conditions of crop failure. Most engagements exempt farmers from giving rice to rice owners as a cost of using rice fields, while others require farmers to give rice to rice owners as rice field use fees.

A pandemia da Síndrome Respiratória Aguda Grave do Coronavírus 2 (Sars-Cov-2) declarada pela Organização Mundial de Saúde (OMS) em janeiro de 2020 vem se estendendo ao longo de 2022 caminhando para seu terceiro ano. Porém atualmente a pandemia encontra-se emum cenário diferente dos períodos iniciais, tanto em seus protocolos de prevenção e vacinação quanto nas novas cepas e seus sintomas. Dentro desse contexto, a geografia junto ao geoprocessamento reafirma sua importância na capacidade de realização de análises espaciais e tomadas de decisões frente a essa conjuntura sanitária.  Dessa forma, o presente trabalho tem como objetivo espacializar e analisar os casos de COVID-19 no município de São Gonçalo-RJ ao longo de todo período pandêmico, onde ocorreram um aumento significativo de casos em quatro períodos: fevereiro até maio de 2020, setembro até dezembro de 2020, fevereiro a maio de 2021 e novembro de 2021 até janeiro de 2022. Para isso, foram realizados os georreferenciamento pela plataforma do ArcGis 10.8.2 de casos acumulados nos meses por bairro e em seguida esses casos foram associados como pesos aos respectivos centroides de cada bairro de São Gonçalo. Posteriormente, foi utilizada a fórmula de Hermuche, 2013 para obter os vetores de deslocamento. Dentre os resultados percebeu-se que as quatro ondas embora apresentem comportamentos distintos, o vetor de direção sempre acaba tendendo a ir a nordeste do município devido a influência do bairro Jardim Catarina.

A metodologia deste trabalho está dividida em duas etapas: a) leitura e interpretação do mapa de relevo da América do Sul; b) demonstração da caixa de areia para o público alvo, discutido com eles as dinâmicas das formas de relevo e da bacia hidrográfica, de forma interativa. Como resultado, percebeu-se que o uso da metodologia de realidade aumentada no ensino de Geografia é essencial para o desenvolvimento das noções cartográficas, como da altimetria do relevo e visão tridimensional, além de possibilitar o aprendizado da dinâmica morfológica do relevo e do sistema bacia hidrográfica, tornando a aprendizagem mais dinâmica e atrativa.
ENTRE RECUSAS E INVENÇÕES SE FAZ O MODERNO
Authors: Scovino Felipe
Published: January 2024

O artigo demarca o início da produção dos Aparelhos cinecromáticos, de Abraham Palatnik, em 1951 até a sua participação na Bienal de Veneza em 1964. Reflete sobre o campo de forças que agia na discussão sobre o desenvolvimento da arte abstrata no Brasil nos anos 1950. As críticas negativas e o reconhecimento desse artista cinético expõem os embates acerca do novo na arte assim como a constituição de uma ideia de moderno nas artes visuais brasileiras. Coloca-se em questão o fato de que a construção desse campo, em particular a obra de Palatnik, passa também por uma complexa rede regida por ambiguidades como reconhecimento e recusa; gambiarra e ciência; celebração e contestação.
ENTORPECIMENTO POR MEDIAÇÃO
Authors: Bastos Marcus
Published: January 2024

O artigo debate a forma como o saber científico perdeu importância no contexto de notícias falsas que toma conta dos processos contemporâneos de mediação em rede. Há um questionamento sobre até que ponto os processos de entorpecimento pelo excesso de informação podem vir a ser responsáveis por uma alienação do usuário, resultando na anestesia de seu senso crítico. Este debate leva em conta exemplos de confusão entre ficção e realidade na história das mídias, como a fuga da sala de cinema quando o trem se aproxima do primeiro plano nas primeiras projeções dos Lumière, a transmissão de Guerra dos Mundos na CBS e a confusão entre a chatterbot Eliza e uma pessoa real.

Authors: Terra Fábio Henrique Bittes , Roquetto Guilherme
Published: January 2024

Investiga-se empiricamente o canal do portfólio de transmissão da política monetária para o caso brasileiro entre janeiro de 2002 e junho de 2018. Testaram-se as relações estatísticas entre a Selic e o índice do mercado de ações brasileiro, o Ibovespa. Empregou-se econometria multivariada com a inclusão, além da Selic e Ibovespa, do Federal Funds Rate, câmbio nominal e índice de produção industrial. As estimações verificaram relações de equilíbrio de longo prazo entre as variáveis, e viabilizaram concluir que o Banco Central do Brasil possui moderada capacidade de influenciar a alocação de portfólios dos agentes ainda que de maneira defasada.

Published: January 2024

This research explores the legal aspects of Indonesia’s Housing Savings Law (Tabungan Perumahan Rakyat, Tapera). The study examines constitutional housing rights, challenges, and government involvement in housing financing, and underscores legal politics for equitable living environments. In line with Indonesia’s 1945 Constitution, which aims to enhance the people’s well-being, including their right to affordable and suitable housing, this is explicitly addressed in Article 28H, paragraph (1), emphasizing the right to live in physical and spiritual prosperity and have decent living conditions. The right to housing is clearly established as a human right in Law No. 39 of 1999 on Human Rights. However, challenges persist in providing affordable and accessible housing, as well as securing sustainable long-term funding. To address this, the government introduced Law No. 4 of 2016 on Public Housing Savings. This study examines the legal politics of this law, focusing on ensuring adequate and affordable housing for citizens. It emphasizes constitutional housing rights, challenges in meeting housing needs, and the government’s involvement in housing financing. The study concludes by underlining the importance of legal politics in ensuring fairness and creating a secure living environment.
Political party financing regulation and gaps for corporate donations: Case of the developing country
Authors: Ilham Teguh , Sari Agni Grandita Permata
Published: January 2024

The excessive corporate involvement in funding political parties jeopardizes the quality of performance of political parties (Mietzner, 2015). This paper aims to analyze the extent to which existing regulations govern the finances of political parties and to find gaps that corporations and political parties often exploit. Moreover, this paper practically seeks to provide practical policy recommendations. This study used qualitative methods, including in-depth and semi-structured interviews with seven purposefully selected informants. This study also involved library research through the collection of various regulations, factual data, and expert opinions from various secondary sources, namely the government and non-governmental organizations. The study found that existing regulations play a very limited role in maintaining the integrity of political parties. The issues found range from irrational donation limits, unregulated spending limits, and incomprehensive financial statements, as well as low supervision and law enforcement by election organizing agencies. Criminal acts against organizations, committed by both corporations and political parties, are still left unaddressed by the law enforcement. Therefore, this paper recommends the formulation of a law that specifically regulates political party finances. Independent institutions that can oversee the parties’ finances as well as legal breakthroughs is also essential in promoting transparency and honesty.

Published: January 2024

The techniques for chitosan extraction from indigenous crabs were assessed using physicochemical properties of the chitosan, and its utilization in the treatment of crude oil polluted water was investigated. Physicochemical properties, heavy metal analytic method (AAS), and hydrocarbon analysis (GC-MS method) of the water samples were employed for this investigation. Results obtained from the physical and chemical properties of the chitosan extracted from indigenous crabs (Scylla species) showed a comparable percentage yield (53% and 50%) compared to synthetic chitosan (72%). The pH values obtained from the chitosan ranged from 6.9 – 13.0, while the percentage degree of deacetylation (DDA) ranged from 60 – 75%. The water quality obtained from Ochani River, filtered with chitosan, yielded the best result with chitosan C compared to chitosan B. The heavy metal content in the polluted Ochani River was totally removed with the control (synthetic chitosan A) compared to chitosan C, which showed a comparably reduction. However, the bio-filtration with chitosan B also revealed better reduction compared to chitosan A. The study established that irrespective of the crude method applied in the extraction of the chitosan from indigenous crabs, its efficacy in treating crude oil-polluted Ochani River was highly impactful.

Solar urticaria is a rare photodermatosis with several unknown pathogenic, clinical and therapeutic aspects. This study analysed the clinical and therapeutic features of a long-term follow-up solar urticaria cohort, with a focus on omalizumab management and outcomes, and characterized omalizumab response with the use of the high-affinity immunoglobulin E (IgE) receptor (FcεRI) and the Urticaria Control Test. An observational, unicentric, ambispective study was conducted from 2007 to 2023. Solar urticaria was diagnosed in 41 patients with a median follow-up of 60 months. Thirteen patients were prescribed omalizumab, with a median treatment time of 48 months. A significant decrease in FcεRI baseline levels and subsequent median increase in Urticaria Control Test was evidenced after omalizumab prescription in all patients. Drug survival at 48 months was at 88.9%. Omalizumab stepping-down protocol led to sustained omalizumab discontinuation in only 1 patient. Median basal Urticaria Control Test was lower (p < 0.01) in patients who were prescribed omalizumab and in patients without remission. This study contributes to our knowledge of omalizumab outcomes in real-life clinical practice and highlights the pathogenic importance of IgE-mediated pathways in solar urticaria, where FcεRI emerges as a possible biomarker of omalizumab response.
