Authors: Ritonga Raja , Akhyar Akhyar , Tambunan Jannus , Muda Andri 
Published: November 2024

Praktek kewarisan islam merupakan hal mutlak yang berlaku pada setiap adanya peristiwa kematian. Namun, pelaksanaanya kurang massif di tengah-tengah masyarakat. Sehingga muncul sebuah fakta bahwa pengamalan kewarisan islam berbanding lurus dengan pemahaman masyarakat terkait ilmu faraidh. Sejumlah pendekatan dilakukan untuk memahami teori kewarisan islam secara komprehensif agar dapat diamalkan dengan baik dan benar. Penelitian ini akan menguraikan terkait sistematika kewarisan islam melalui konsep syajarotul mirats. Adapun metode yang digunakan dalam kajian ini adalah metode kualitatif dengan jenis penelitian kepustakaan. Dalam pengumpulkan data-data, peneliti melakukan penelusuran sejumlah kitab dan karya ilmiah lainnya berupa jurnal yang memiliki relevansi dengan tema penelitian. Selanjutnya data dianalisis dengan menggunakan content analysis. Sebagai hasil, penelitian menjelaskan bahwa konsep syajarotul mirats dapat memetakan posisi masing-masing ahli waris berdasarkan garis kekerabatannya kepada pewaris. Selain itu, pada konsep ini juga dapat diuraikan bagian masing-masing ahli waris secara detail.

Published: November 2024

Globally, energy challenges are increasing with population growth. Many countries solely depend on fossil fuels (oil, coal, natural gas, etc.) for energy generation for different processes. Fossil fuels fall under non-renewable energy sources, are polluters of the environment, and get depleted faster, thus making it challenging to sustain a continuous energy supply. Therefore, there is a need for alternative sources of energy to mitigate the hazards associated with the utilization of fossil fuels. The present study aims to monitor the performance of a three-meter cubic (3 m3) greenhouse biogas digester, focusing on the temperature effect in biodegrading cow dung materials for gas generation. The study was conducted under mesophilic temperature conditions, pH, and hydraulic retention time for 30 days. Results revealed that slurry temperatures of about 33.5 ℃ and ambient temperatures of about 35 ℃ resulted in a remarkable peak biogas yield of 0.3 m3 on the 23rd day of the month. After the optimum yield of the biogas, the performance declined and was ascribed to the non-supply of the new feedstock, and the environment in the reactor became acidic, hence hindering the biodegradation process. Ultimately, the total biogas yield obtained from the study was 2.58 m3, equivalent to 15.48 kWh of energy. This amount of bio-generated energy was twofold the average daily electricity consumption of middle-income South African households. It was demonstrated that temperature was a major factor influencing the performance of the assembled biogas digesters and, thus, should be closely monitored for appreciable biogas production. This study is envisaged to pave the way for the future affordable and environmentally friendly biogas production process.

De rechtsmiddelenverwijzing: voorstellen voor verbetering
Een rechtsmiddelenverwijzing maakt de burger attent op het recht om bezwaar aan te tekenen of in beroep te gaan. In dit artikel wordt de aandacht gevestigd op gebreken die kleven aan in de praktijk gebruikte rechtsmiddelenverwijzingen en worden voorstellen voor verbetering gedaan.In rechtsmiddelenverwijzingen zou in duidelijke taal moeten worden aangegeven dat een voorlopig (pro forma) bezwaar of beroep kan worden ingediend. Dit kan veel burgers helpen en de feitelijke rechtsongelijkheid tussen de gewone burger en de ‘ingewijden’ op dit terrein verminderen. Een wetswijziging is hiervoor niet vereist. De overheid moet in ‘klare taal’ aangeven wat de burger moet doen en wat zijn mogelijkheden zijn, waarbij ook heel duidelijk moet worden aangegeven wat de consequenties zijn van het niet op tijd instellen van (pro forma-) bezwaar of beroep.Overwogen kan worden om in plaats van de vermelding van de termijn in weken (‘binnen zes (6) weken’) of dagen een einddatum te noemen. De burger weet dan precies hoeveel tijd resteert om actie te ondernemen, en is misschien daardoor beter in staat om binnen de termijn te reageren. Gelet op het risico van vertragingen bij postbezorging kan daarbij, zeker in (financiële) tweepartijengeschillen, een geschil tussen één burger en de overheid waarbij verder geen belangen van derden zijn betrokken, in het voordeel van de burger worden gerekend. Het gaat hier om het fundamentele recht van toegang tot de rechter, en de rechter zal dan ook moeten controleren of niet door het noemen van een einddatum de termijn is ingekort.

Mededingingstoezicht in beweging
Zowel de vruchten van mededingingsbeleid als empirische aanwijzingen van toenemende marktconcentratie en winstmarges, onderstrepen het belang van concurrentietoezicht. Frequente marktstudies en aanvullend instrumentarium kunnen haperende concurrentie weer aanzwengelen en ongewenste concentratievorming helpen voorkomen. Heldere uitgangspunten en randvoorwaarden vormen een kompas om eerlijke en dynamische concurrentie te beschermen, ook in wisselwerking met andere publieke belangen.

Authors: Acosta Villagran Laura , Arzate Fernandez Amaury Martín , García Núñez Hilda Guadalupe , Martínez Martínez Sandra Yarenssy , Hernández Solís Monserrat , Reyes Díaz Jesús Ignacio 
Published: November 2024

<p><strong>Background:</strong> <em>Agave cupreata</em> is a specie that can only reproduce by seeds and could take up to 15 years until flowering, placing it at risk of extinction due to its agroindustrial exploitation to produce mezcal. <strong>Objective:</strong> To evaluate the type of explant, the vitamin complex and 2,4-D concentrations on the direct embryogenic response. <strong>Methodology:</strong> Explants of leaf, root and stem sections were evaluated. Also, the vitamins MS (Murashige and Skoog, 1962) and L2 (Phillips and Collins, 1979), five concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D), (0.0, 0.1, 0.3, 0.6 and 0.9 mg L<sup>-1</sup>) and six concentrations of indole-3-acetic acid (IAA), (0.0, 0.1, 0.5, 1.0, 2.0 and 3.0 mg L<sup>-1</sup>) were assayed for the expression of somatic embryos directly. <strong>Results: </strong>The leaf explant, the vitamin L2 complex, and the concentration of 0.9 mg L<sup>-1</sup> of 2,4-D and 0.5 mg L<sup>-1</sup> of IAA turned out to be the most efficient for the formation of pro-embryogenic masses and the expression of direct somatic embryos in the globular state. <strong>Implications:</strong> These results lay the groundwork for the future regeneration of <em>A. cupreata</em> plants via direct somatic embryogenesis, potentially facilitating their conservation and mass propagation. This contributes to the sustainability of mezcal; boosts the local economy, preserves biodiversity, and ensures the continued production of this endangered species. <strong>Conclusions:</strong> For the first time, the successful expression of somatic embryos directly from <em>A. cupreata</em> explants was evidenced.</p>

Authors: Rodríguez-Ibarra Luz Estela , Abdo-de la Parra Maria Isabel , Velasco-Blanco Gabriela , Martinez-Brown Juan Manuel 
Published: November 2024

<p><strong>Background:</strong> Interest in ornamental marine fish, especially species associated with coral reefs, is rapidly growing. Most of the fish traded come from the wild, and collection methods harm coral reefs and cause massive mortalities in non-target species. To make the activity sustainable, it is necessary to develop aquaculture biotechnologies to reduce the collection of wild organisms and lessen the pressure on their natural environment. <strong>Objective:</strong> To develop protocols for the reproduction and larval rearing of the maroon clownfish (<em>Premnas biaculeatus</em>) for the sustained production of juveniles in captivity. <strong>Methodology:</strong> Two pairs of <em>P. biaculeatus</em> were placed in two aquariums of a recirculating system with filtered seawater. The obtained eggs were incubated in 100 L tanks. The larvae were fed with rotifers <em>Brachionus rotundiformis</em>, <em>Artemia</em> sp. nauplii, and weaned onto a commercial diet. The larvae were measured at hatching and every four days until weaning. <strong>Results:</strong> The clownfish pairs began spawning 4-5 months after being placed in the recirculating system and continued spawning every 15-20 days. The eggs hatched 6-7 days after fertilization (DAF), and the hatched larvae measured 3.4±0.06 mm in total length (TL). At 19 days after hatching (DAH), after completing weaning, they measured between 9.8 to 11.5 mm in TL; at 26 DAH, they measured between 10.8 to 13.1 mm. After one month, between 800 to 1,000 juveniles were obtained for commercialization. <strong>Implications:</strong> The reproduction and larval rearing protocols of the maroon clownfish <em>P. biaculeatus</em> described in this work can be used to obtain juveniles in captivity for commercialization; additionally, they can serve as a basis for developing other protocols for obtaining juveniles of other ornamental marine fish species for commercialization, contributing to the protection of their natural environment. <strong>Conclusion:</strong> The results obtained demonstrated the viability of maintaining <em>P. biaculeatus</em> breeders in captivity and achieving their natural reproduction, larval rearing, and mass production of juveniles throughout the year.</p>

Study on Phase Evolution of Calcium Silicate Hydrate (C-S-H) During Solidification of Cr(VI) under Hydrothermal Conditions
Authors: ZHAO Zhiguang , QU Xiaoling , LI Zhanming , TIAN Changan , LI Zaibo 
Published: November 2024

In this paper, calcium silicate hydrate (C-S-H) was synthesized by hydrothermal method using CaO and quartz sand as raw materials. The solidification effect of Cr(Ⅵ) in C-S-H was studied using XRD, FTIR, and SEM. The leaching amount of Cr(Ⅵ) after solidification was determined by anatomic absorption spectrometer to analyze and calculate the solidification rate of Cr(Ⅵ). Results show that appropriately increasing the reaction temperature and prolonging the reaction time can help improve the crystallinity of C-S-H. A small Cr(Ⅵ) dosage of Cr/Si < 0.05 is beneficial for the crystallization of C-S-H, but when Cr/Si > 1.0, Cr(Ⅵ) ions inhibit the formation of C-S-H. When Cr/Si <0.15, the solidification efficiency of C-S-H on Cr(Ⅵ) decreases with increasing Cr(Ⅵ) content; The C-S-H with Ca/Si = 1 has the best solidification efficiency for Cr(Ⅵ).
ПОСТАТЬ ВАСИЛЯ ПОРАЙКА У СВІДЧЕННЯХ МИКОЛИ МЕЖУЄВА (за матеріалами слідчої справи)
Authors: Бойда Андрій 
Published: November 2024

Метою статті є спроба реконструкції біографії маловідомого в історіографії наркома комунального господарства УСРР (1935–1936) М.Д. Межуєва та постаті В.І. Порайка за матеріалами кримінальної справи, заведеної НКВС на Межуєва влітку 1937 р. Наукова новизна. Уперше проведено реконструкцію історичного портрета Миколи Дмитровича Межуєва (1899–1937), маловідомого в історіографії більшовицького партійного та профспілкового діяча радянської України. Основні акценти зроблені на його діяльності як керівника партійних, профспілкових і комунальних організацій УРСР. У науковий обіг введені раніше невідомі документи, що стосуються М.Д. Межуєва, а також В.І. Порайка та найближчого оточення цього партійного і державного діяча із його київського періоду діяльності (1934–1937). Методи дослідження. Використання методів джерелознавчого аналізу сприяло систематизації первинної інформації (кримінальні справи на В.І. Порайка, М.Д. Межуєва, інші архівні документи), а використання історико-системного методу дозволило дослідити основні моменти з біографії наркома комунального господарства УСРР М.Д. Межуєва (1899–1937) та його свідчення про його керівника – В.І. Порайка, узагальнення отриманих відомостей. Висновки. Під час пошукової роботи вдалося встановити, що Микола Дмитрович Межуєв (6.12.1899–24.10.1937) був ключовим «свідком» у справі щодо обвинувачення В.І. Порайка. Зважаючи на директиви з Кремля, жорсткі методи та стислі строки слідства, а також відсутність самої можливості для оскарження рішення суду та його негайне виконання, «покази» свідка (підозрюваного чи обвинуваченого) були потрібні лише для отримання формальних підстав для наступних арештів й обвинувачень інших українських державних та партійних діячів, так званих українізаторів, серед яких був і В.І. Порайко, в антирадянській націоналістичній діяльності.

Published: November 2024

Este trabalho teve por objetivo discutir, através de estudo de casos, metodologias para determinar a resistência à fadiga de tubulações industriais através da realização de análises dinâmicas utilizando vibrações medidas. O estudo visou fornecer subsídios para propiciar o desenvolvimento de procedimentos para evitar problemas de fadiga relacionados a vibrações em tubulação. Um levantamento bibliográfico foi realizado, documentando os critérios e procedimentos propostos pela literatura pertinente. As medições de campo foram realizadas com acelerômetros e fornecidas através de espectros de deslocamentos. As simulações numéricas foram realizadas com o programa ANSYS, de acordo com a norma de projeto aplicável. Devido às características das medições disponíveis, o estudo de casos se limitou à extração de frequências naturais e modos de vibração e análises harmônicas. A comparação das frequências naturais e seus modos de vibração visa determinar não só quais os modos de vibração que estão sendo excitados como seus fatores de amplificação. As análises harmônicas, por sua vez, permitiram determinar as tensões ocorrentes.
Otimização de representações tempo-frequência na análise de falhas em sistemas engrenados

Published: November 2024

A inclusão de sistemas capazes de monitorar o desenvolvimento de falhas em componentes como engrenagens tem sido uma importante tarefa nas fases de projetos e manutenção. Freqüentemente, os sinais de vibração gerados por estes sistemas são do tipo multicomponentes e não estacionários, gerados por forças do tipo transientes que aparecem do contato da superfície do dente com alguma imperfeição, desenvolvido na forma de vibrações que excitam varias freqüências de ressonância do sistema. A analise espectral clássica aplicada na detecção de falhas, apesar de ser a mais difundida e permitir diagnósticos importantes, tem apresentado limitações, especialmente com respeito a componentes espúrias que aparecem e que contaminam o espectro, dificultando a interpretação para o analista. A fim de minimizar estes problemas este trabalho investiga uma representação conjunta tempo freqüência denominada distribuição Pseudo WignerVille (PWV), com o objetivo de oferecer um novo discernimento sobre a interpretação destes sinais, evidenciando mais o fenômeno físico causado por vibrações transientes e permitindo separar as componentes do sinal causadas por diferentes fontes. As representações dos mapas tempofreqüência foram analisados a partir de dois tipos de sinais: o sinal convencional e um sinal que usa o conceito de transformações homomórficas, aqui denominado de sinal residual. Como resultado desta investigação pôdese concluir que as distribuições PWV obtidas a partir do sinal residual mostraramse mais adequadas à analise que a distribuição PWV calculada a partir do sinal convencional, contendo informações mais precisas sobre falhas simuladas e obtidas de uma bancada experimental, o que sugere sua implementação em condições reais de falhas nestes sistemas.
