Judicial competence within the scope of judicial power includes general and religious courts. The explanation in Law No. 7 of 1989 regarding religious courts still provides a choice of law for those who litigate and adhere to Islam. This study aims to determine the legal position of the Bandung District Court decision No. 166/Pdt/G/1991/PN.BDG after the amendment of Law No. 7 of 1989. The research method used is descriptive analytical by using literature study and using secondary and primary legal sources and interviews. The results showed that the decision of the Bandung District Court No. 166/Pdt/G/1991/PN.BDG was based on the competence of the Religious Courts contained in Law No. 3 of 2006 after the amendment of Law No. 7 of 1989 regarding Religious Courts. Bandung District Court Decision No. 166/Pdt/G/1991/PN.BDG is null and void because the settlement of property and inheritance disputes for those who are Muslims must be resolved through the Religious Court because Law No. 3 of 2006 does not recognize the choice of law for those who are Muslims in resolving property and inheritance disputes as previously regulated in Law No. 7 of 1989.Keywords: Bandung District Court Decision No. 166/Pdt/G/1991/PN.BDG, UU No. 7 of 1989

In numerous regions of the globe, armed conflicts occur, causing not a few casualties in addition to physical destruction. Weapons of Mass Destruction (WMD) or commonly referred to as weapons of mass destruction have become one of the most dreaded weapons with the emergence of chemical, nuclear, radiological, biological, and explosive weapons. In fact, the use of weapons of mass destruction has been outlawed, but production remains unsupervised, allowing a number of so-called terrorists to use readily available chemical weapons raw materials, such as Triacetone Triperoxide (TATP), to manufacture bombs and the like. In addition, chemical weapons whose circulation in liquid and gas forms is not monitored by the Chemical Weapons Convention (CWC) pose a risk of long-term damage such as permanent burns or diseases that continue to plague victims long after the war has ended. The following events are certainly a threat to national security that can be caused by irresponsible individuals with access to chemicals. Therefore, it is necessary to prevent similar occurrences in order to minimize the damage they cause. Through in-depth interviews and secondary data analysis, this study aims to establish the truth. Consequently, participation from relevant stakeholders is required. Where the threat is an effort, work, activity, or action that is deemed a threat to the security, safety, and resilience of the Unitary State of the Republic of Indonesia and various national interests. The authorities supervise the licensing, purchase, and use of these precursors as detailed below. Therefore, it is necessary to develop a new and unique regulation for precursors circulating in Indonesia.

The article presents a one-stage method for the synthesis of effective plasticizers and antioxidants with a heterogeneous catalyst under mild conditions with a high yield. In order to obtain plasticizers and antioxidants, a number of studies were carried out to determine the optimal temperature, amount of catalyst and molar ratio of reacting components based on natural petroleum and aliphatic fatty acids (C6-C8) using a heterogeneous catalyst. Based on the studies carried out under optimal conditions (temperature -110-120°C, the amount of catalyst – 1,5 wt.%, acid, the molar ratio of components - acid: alcohol - 2:1,4), mixed diesters were synthesized with a yield of 88-90%. To confirm the structures of the synthesized diesters on the "Alpha" IR Fourier spectrometer, the corresponding IR-spectra were obtained, where the absorption bands characteristic of the carbonyl and ester functional groups appear with greater intensity. The good compatibility of the synthesized plasticizers with the polymer matrix and the effect of these compounds on the reduction of sludge in diesel fuel are shown.

Published: July 2023

Efficient cargo packing and transport unit stacking play a vital role in enhancing logistics efficiency and reducing costs in the field of logistics. This article focuses on the challenging problem of loading transport units onto pallets, which belongs to the class of NP-hard problems. We propose a novel method for solving the pallet loading problem using a branch and bound algorithm, where there is a loading order of transport units. The derived algorithm considers only a heuristically favourable subset of possible positions of the transport units, which has a positive effect on computability. Furthermore, it is ensured that the pallet configuration meets real-world constraints, such as the stability of the position of transport units under the influence of transport inertial forces and gravity.

Transfer pricing is a price transfer policy in a transaction carried out by a certain party and following the applicable laws and regulations. Many companies take advantage of this for other purposes, namely avoiding taxes. Tax evasion is a complicated matter and is an act that does not violate the law, but on the other hand, tax evasion is not accepted by the government because it can reduce the amount of income sourced from taxes. The type of research used in this research is explanatory research with a quantitative approach. The population in this study is all manufacturing companies in 2019-2021, with a total of 116 companies. Sampling was done by purposive sampling. The results of the simultaneous research of the three variables do not influence transfer tracing. While partially only the Tunneling Incentive variable (X2) has an effect, the Debt Covenant (X1) and Bonus Mechanism (X3) have no effect. For future researchers, adding other variables and expanding the research sample are suggested.

Published: July 2023

O carcinossarcoma uterino é neoplasia rara; apresenta em sua estrutura elementos indiferenciados do estroma endometrial e elementos sarcomatosos homólogos ao útero. A taxa observada de aparecimento destas lesões na população é de 0,8 por 100 mil mulheres. Ocorre com freqüência maior entre as mulheres que se submeteram à radioterapia, atingindo a taxa de 4,3 por 100 mil mulheres nesta população selecionada. A relação entre a radioterapia e o desenvolvimento de carcinossarcoma uterino não pode ser comprovada estatisticamente, dada à raridade da neoplasia, mas provavelmente a radioterapia é um importante fator para o desenvolvimento posterior de tais tumores. Por essa razão, é fundamental o acompanhamento a longo prazo de mulheres que se submeteram à radioterapia pélvica. Apresentamos o caso de uma paciente tratada de câncer de colo uterino há 14 anos, com radioterapia exclusiva, e que retornou ao serviço apresentando carcinossarcoma uterino.

Published: July 2023

The poisoning of agricultural soils with heavy metals (HMs) is a severe threat to the worldwide food supply, human health, and plant life. The health and production of crops are negatively impacted when HM levels in agricultural soils reach hazardous levels. The major heavy metals are chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), mercury (Hg), zinc (Zn) and copper (Cu). These metals may be found everywhere in the environment, including in things like soil, food, water, and even air. These materials cause changes in the properties of soil and also harm plants, which reduces crop production. Crop type, growth conditions, elemental toxicity, developmental stage, soil chemical and physical properties, and the presence and bioavailability of HMs in the soil solution are all factors that affect how toxic HMs are to crops. By interfering with their normal function and structure in cellular components, HMs can hinder a variety of metabolic and developmental processes. Humans are susceptible to a wide range of serious diseases when they consume these affected plant products. The kidneys, brain, intestines, lungs, liver, and other organs in the human body are all negatively impacted by exposure to these metals. This review assesses (1) contamination of heavy metal in soils through different sources, like Anthropogenic and natural; (2) the effect on microorganisms and the chemical and physical properties of soil; (3) the effect on plants as well as crop production; and (4) entering the food chain and associated hazards to human health. Finally, we found some research gaps and indicated future work. The discharge of heavy metals into the environment must be strictly regulated if people are to feel secure in their surroundings.
Multimodel approaches are not the best way to understand multifactorial systems
Authors: Bolker Benjamin
Published: July 2023

Information-theoretic (IT) and multi-model averaging (MMA) statisticalapproaches are widely used but suboptimal tools for pursuing a multifactorial approach (also known as the method of multiple working hypotheses) in ecology. (1) Conceptually, IT encourages ecologists to perform tests on sets of artificial models. (2) MMA improves on IT model selection by implementing a simple form of shrinkage estimation (a way to make accurate predictions from a model with many parameters, by “shrinking” parameter estimates toward zero). However, other shrinkage estimators such as penalized regression or Bayesian hierarchical models with regularizing priors are more computationally efficient and better supported theoretically. (3) In general the procedures for extracting confidence intervals from MMA are overconfident, giving overly narrow intervals. If researchers want to accurately estimate the strength of multiple competing ecological processes along with reliable confidence intervals, the current best approach is to use full (maximal) statistical models after making principled, a priori decisions about which predictors to include.

Published: July 2023

Jack pine is undesirable for mechanical pulping compared with spruce and balsam fir. In this work, the authors use chemical and chemimechanical techniques to improve the papermaking properties of jack pine TMP long fibers. Chemical techniques included TEMPO-mediated oxidation (TOX) and alkaline peroxide (AP) treatment. Some pulps were beaten in a domestic blender. Results indicated that TOX alone or in combination with AP yielded excellent results. When used alone, AP treatment resulted in little improvement in handsheet properties. However, it gave excellent results when followed by beating.
Pre-extraction of hemicelluloses and subsequent kraft pulping
Part I: alkaline extraction
Authors: WAFA AL-DAJANI WALEED , TSCHIRNER ULRIKE W.
Published: July 2023

A mild alkaline treatment was applied to aspen chips prior to kraft pulping in order to extract hemicelluloses for use as biofuels. The extraction was performed at 50-90° C, and did not require costly pressurized reaction vessels. It resulted in a recovery of 40-50 kg of hemicellulose per ton of chips, and yielded the same amount of pulp after subsequent pulping of the extracted chips residue, as compared to a control cook. The pre-extraction process requires careful optimization of the pulping process, and allows shorter cooking time and lower chemical charges.
Kraft pulps obtained from pre-extracted chips have a slightly higher cellulose/hemicellulose ratio, and demonstrate a small decrease in tensile index (~10%), but improved brightness and shive content. While the hemicellulose yield for this process is low, this problem is outweighed by the fact that pulp properties and pulping yield can be maintained at a high level. The recovered hemicellulose can be concentrated/isolated more easily than furfural-containing smaller fragments obtained by autohydrolysis or dilute-acid treatment.
Determination of the mineral constituents of recycled paper mill sludge
Authors: KRIGSTIN S.G. , SAIN M.
Published: July 2023

Innovative uses for recycled paper mill sludge are required to improve the industry’s sustainability. While purified fractions of sludge may prove to be of greater value for targeted applications, rapid and accurate characterization of these heterogeneous waste materials is becoming essential. We examined three methodologies for determining the mineral composition of recycled paper mill sludge. We found thermogravimetric analysis (TGA) to be a fast and precise method for determining calcium carbonate based on its thermal decomposition temperature. Total ash content of recycled paper mill sludge determined at 700°C had a strong correlation to the traditional TAPPI ash. We evaluated fractionation methodologies using TGA and found that fiber-rich and inorganic rich-portions could be produced by dry screening recycled paper mill sludge.
FEMININE DEATH AS SACRIFICE IN THE LITTLE MATCH GIRL, DEAD MEN’S PATH, AND THE STORY OF AN HOUR

Published: July 2023

This research article discusses feminine death in three short stories: The Little Match Girl (1906) by Hans Christian Andersen, Dead Men's Path (1972) by Chinua Achebe, and The Story of an Hour (1969) by Kate Chopin. It aims to reveal the existence of extremity and sacrifice in the death of a woman. This study used a qualitative-descriptive design to reveal and investigate the phenomena and forms, or modes, of women's deaths. The theory of feminine death from Elizabeth Bronfen (2017) is used to reveal the extremity and sacrifice of a woman, and the theory of philosophical death and female finitude from Linnell Secomb (1999) is used to reveal the mode and symbols of feminine death. Based on Spradley's theory and analysis, we argue that the three short stories all have extremity and sacrifice; in the short story by Hans Christian Andersen, there is a mode or form of death called "being-towards-death." Furthermore, in the work of Chinua Achebe, there is a mode of death called "the master-slave battle to the death." Lastly, Kate Chopin produced "dwelling-with-death". The three short stories can be found in extremity, sacrificing, and feminine modes of death. Thus, the identification can reveal the feminine death phenomenon in the short story.

Research on livelihood systems tends to focus on livelihood assets, the transformation of structures, processes, and livelihood outcomes. During disasters, livelihood systems are disrupted, and various socio-economic issues may arise if not properly addressed. This research provides a perspective on social-economic mitigation institutions in the context of community livelihood systems in disaster-prone areas. The research advocates the need for economic mitigation institutions in vulnerable communities in disaster-prone regions. The framework of these economic mitigation institutions emphasizes economic commodification schemes. This research examines the institutional dynamics communities implement in economic mitigation as part of their livelihood systems in disaster-prone regions. This research adopts a qualitative constructivist approach to construct a new conceptual framework for disaster mitigation. Data is collected through in-depth interviews and focused group discussions (FGDs). The findings show that various insights provide potential solutions for disaster-prone livelihood systems based on theoretical analysis and empirical findings from disaster-prone areas in Indonesia. Economic mitigation institutions are crucial for vulnerable communities and essential for sustainable development. Moreover, communities residing in disaster-prone areas naturally develop survival strategies by utilizing available resources.
Optimization of the Engineering Properties of Cement Concrete Containing Gravel and Waste Rock Using Dense Packing and Response Surface Methodology
Authors: Nguyen Van Minh , Nguyen Van Minh , Nguyen Viet Anh
Published: July 2023

This study introduces a novel methodology for optimizing the distribution of aggregate particles in concrete. Utilizing locally available materials like gravel and waste rock is explored as a sustainable alternative to conventional materials like mountain rock and river sand, which are depleting. Determining the maximum bulk density involves an efficient process of gradually adding different particle sizes of gravel and waste rock to the mixture. The vibrational compaction of the container aids in identifying the optimally combined percentages of these aggregates. Besides, the study also addresses the issue of porosity in concrete. The response surface methodology is employed to optimize the mixture proportions for concrete, considering important factors such as workability, compressive strength, flexural strength, and elastic modulus. This response surface methodology allows for the development of mathematical models that aid in determining the optimal mix ratios. By exploiting the potential of gravel and waste rock, this study aims to procedure cement concrete containing gravels and waste rock (WR) with required compressive strength from 30 MPa to 35 MPa based on reasonable aggregate particle distribution in combination with response surface methodology (RSM) and minimize the disposal of non-biodegradable waste, thereby reducing the environmental pollution. Additionally, utilizing locally available materials helps to effectively use the region's resources for concrete production, promoting sustainability and reducing dependency on scarce resources. The proposed method presents a promising approach to optimizing aggregate distribution in concrete while considering the environmental and resource constraints specific to the Northwest region of Vietnam.

Решение нелинейной связанной задачи, описывающей деформирование грунта при оттоке жидкости, имеет практическое применение, например, при моделировании деформирования дорожного полотна или при расчете неравномерной осадки инженерных сооружений. Уплотнение водонасыщенных дисперсных грунтов под нагрузкой, как правило, нелинейное и сопровождается большими деформациями, поэтому разработка геометрически и физически нелинейной связанной модели консолидации, учитывающей упругопластическое поведение материала, сопровождающееся изменением пористости и проницаемости, является весьма актуальной. Создание собственного программного кода является целесообразным, так как способствует повышению уровня научного моделирования и программирования в нашей стране. Представляется актуальным исследование устойчивости решения седловой задачи консолидации теоретически в линейном и нелинейном вариантах. В настоящем исследовании сформулирована, математически исследована, обоснована на основе моделей и экспериментальных возможностей механики сплошных сред и численно реализована достаточно общая формулировка задачи совместного деформирования пористой твердой среды с протекающей через поры жидкостью в рамках физической и геометрической нелинейности. Постановка задачи выведена в скоростях перемещений твердой фазы и изменения давления воды в дифференциальном и вариационном виде. Уравнения фильтрации и изменения пористости переформулированы в лагранжевых координатах твердого каркаса согласно подходу ALE (Arbitrary Lagrangian-Eulerian) с использованием относительной скорости движения жидкости. Показана применимость метода Удзавы в качестве основной части метода решения нелинейных задач консолидации. Сходимость итерационного процесса изучена теоретически. Были проведены вычислительные эксперименты решения линейной задачи для подтверждения теоретической скорости сходимости итерационного процесса. Вычислительные эксперименты не только подтвердили теорию, но и добавили различные аспекты относительно характера сходимости, не улавливаемые теоретическим рассмотрением.

Распределённая гравитационная нагрузка также приводится к узлам конечно-элементной модели. КА считается абсолютно жестким телом, с которым связывается подвижная координатная система, совершающая движение относительно некоторой инерциальной системы координат. Участки выпущенной части троса считаются прямолинейными. Сила натяжения и продольная деформация троса считаются в пределах конечного элемента постоянными величинами. Искомыми неизвестными задачи являются координаты узлов конечно-элементной модели и узлы поворота КА относительно инерциальной системы координат. Дифференциальные уравнения движения космического аппарата с выпускаемым тросом составляются на основе принципа возможных перемещений в обобщенных координатах с учётом нелинейностей упругих и инерционных сил. Полученная в результате замкнутая система нелинейных дифференциальных уравнений позволяет определить зависимости искомых величин от времени. В качестве примеров приводятся решения двух консервативных задач: о падении закрепленного в начальной точке троса в плоскости с грузом на свободном конце; о буксировке груза с помощью весомого троса. В задаче о буксировке предварительно была решена нелинейная статическая задача с целью определения начальной конфигурации троса. Решения получены путём численного интегрирования нелинейных уравнений движения методом Рунге-Кутты-Фельберга 4-5 порядков с автоматическим выбором шага. Устойчивость вычислений контролировалась по выполнению закона сохранения полной энергии системы.

В данной статье описана методика определения эффективных механических свойств композитных сетчатых оболочек, изготовленных из углерод-углеродных композиционных материалов, предназначенных для создания лёгких, прочных и жёстких конструкций. Эта методика основана на асимптотическом усреднении дифференциальных уравнений с быстро осциллирующими коэффициентами, и позволяет вместо исходной сетчатой конструкции рассматривать эквивалентную ей конструкцию в виде сплошной оболочки. В структуре сетчатой конструкции, как правило, прослеживается периодически повторяемый фрагмент, который в соотношении с масштабом всей конструкции имеет значительно меньший размер, и поэтому может рассматриваться как ячейка периодичности для метода асимптотического усреднения Бахвалова. Этот метод заключается в разделении процессов, происходящих на разных масштабных уровнях на основе анализа исходных уравнений, представляющих собой в этом случае уравнения с быстро осциллирующими коэффициентами. На масштабном уровне одного периодически повторяемого элемента возникает задача на ячейке, а на масштабном уровне всей конструкции возникает задача для однородной оболочки с приведенными эффективными характеристиками. Соответственно вся задача, согласно методике асимптотического усреднения, разбивается на две задачи: макроуровня для всей конструкции, и микроуровня для периодически повторяемого фрагмента. В данной статье рассматривается задача микроуровня, методика ее решения и зависимость эффективных характеристик от геометрических параметров сетчатой конструкции. При этом рассматривается развертка сетчатой оболочки с периодически повторяемым фрагментом на плоскости, т.е. мы пренебрегаем кривизной оболочки, и ее механическое поведение описывается системой уравнений теории упругости с матричными быстро осциллирующими коэффициентами. В результате мы получаем методику, которая позволяет спрогнозировать оптимальные геометрические характеристики сетчатых конструкций с учётом их жесткостных характеристик. В данной статье приведены численные примеры определения эффективных физико-механических характеристик переходного отсека в виде цилиндрической сетчатой оболочки. Проведено численное исследование зависимости этих характеристик от угла наклона спиралей в сетчатой конструкции. В результате эта методика позволяет выбрать оптимальный угол наклона спиралей в конструкции сетчатого переходного отсека.

В составе гасителей колебаний в различных областях промышленности часто применяются элементы конструкции из эластомерных композитов. Отличительной особенностью эластомерных композитов являются высокие обратимые деформации при малых нагрузках, которые обеспечивают данному классу материалов восприимчивость к воздействию колебаний различной частоты и интенсивности. В настоящей работе были проведены ускоренные испытания по исследованию влияния УФ-излучения на комплекс упруго-прочностных и упруго-гистерезисных свойств эластомерных композитов на основе бутилкаучука и СКЭПТ, наполненных техуглеродом П-324 с добавлением частиц микрошунгита. Исследовались также ненаполненные составы. Образцы выдерживались под УФ лампой в течение месяца. Исследовались упруго-прочностные свойства до и после облучения образцов эластомерных композитов. Для оценки изменения упруго-гистерезисных свойств поверхности образцов применялся метод наноиндентирования. Изменение структуры поверхности образцов эластомерных композитов до и после УФ облучения контролировалось с помощью оптического микроскопа. В ходе эксперимента было установлено существенное влияние добавок технического углерода и микрошунгита на физико-механические характеристики образцов. При воздействии УФ-излучения существенные изменения упруго-прочностных свойств наблюдаются у ненаполненных составов. Упруго-прочностные свойства наполненных составов не претерпели существенных изменений. Для наполненных составов на основе бутилкаучука установлена наибольшая прочность, по сравнению с остальными составами. Максимальное значение относительного гистерезиса при индентировании получено для образцов на основе СКЭПТ наполненных техуглеродом и микрошунгитом. При анализе данных, полученных методом наноиндентирования, выявлено, что добавление микрошунгита замедляет процесс старения образцов под действием УФ-излучения. Установлено, что для образцов эластомерных композитов на основе СКЭПТ и бутил-каучука деструкция полимерной матрицы протекает по разному механизму.

This study aims to analyze the realization of the policy of educational sports development patterns based on sports law. In accordance with the mandate of the sports law that sports education is an important part of nation-building in order to improve the quality of life and human welfare. This study uses a descriptive qualitative approach. This research was conducted in Bogor Regency with the consideration that it is the only region that has a concentration on the development of sports education. This is certainly expected to be a role model for other regions in the development of sports education. Then by conducting observations, documentation studies, and interviews as a tool for data collection. To analyze the data collected, we designed ten indicators based on the essence of sports law in the scope of educational sports. Then, the data is analyzed by referring to the analysis method of the realization of Korten's policy which views three dimensions. The first dimension is the compatibility between the program and the user. Second, the suitability between user groups and the capabilities of the implementing organization. Third, compatibility between user groups and implementing organizations. The results of this study found that the realization of the applied educational sports development pattern policy was close to conformity with what was stated in the sports law. Although, there are still some aspects that are not optimal in their implementation, which is caused by the absence of a good relationship between the three dimensions, namely policies (programs), implementing organizations, and user groups (society). Therefore, the government as the policy maker by collaborating with the community must immediately improve in realizing the pattern of developing educational sports in accordance with the mandate of the sports law.
