Penafsiran Eskatologi Wujudi Mulla Sadra
Authors: Fadel Achmad , Adnani Hasyim , Gama Cipta Bakti Gama , Syam Muhammad Asrul
Published: February 2025

This research This research aims to analyze the eschatological phenomenon in Surah Al-Zalzalah based on the approach of Mulla Sadra's Philosophy of Existence. The eschatological phenomenon described in the Qur'an is an event that can be believed not only through dogmatic methods but also through rational-speculative means. The focus of the events to be discussed here is the Day of Judgment, resurrection (sudur an-nas), and recompense (jaza’). These three events go beyond sensory instruments and scientific testing, making them philosophical issues that are suitable to be understood within a rational-universal framework. Mulla Sadra offers a rational explanation based on the Transcendental Theosophy theory (al-Hikmah al-Muta’aliyyah) to understand the events of the Day of Judgment, resurrection, and recompense. The source of data is taken from Tafsir al-Qur'an al-Karim by Sadra, edited by Khajavi. This research involves a literature review using the Philosophy of Existence theory by Sadra. The results of this study indicate that each eschatological phenomenon is a form of evolution and modulation of existence. Firstly, the Day of Judgment is interpreted as the process of actualization and perfection of material, where the Earth is replaced by another Earth, and every substance undergoes a perfecting movement. Resurrection is the actualization of every potential and the forms of souls toward the original form of each creature. Recompense is the original psychological form of the soul when resurrected, producing either happiness or misery. This interpretation implies a more Sufi approach to religion, attributing every goodness or badness to the condition of the individual soul's form
The Concept Of Human Creation According To Islamic Scholars As A Criticism Of Homo Economicus
Authors: Umam Khairul Umam , Yazidurrahma Akbar
Published: February 2025

Humans who were created with a lot of diversity and abilities and strengths that are more than other living things make them superior in many aspects. But unfortunately, it turns out that this diversity has resulted in the birth of a distorted perspective on world life, especially regarding wealth. Not a few people or individuals judge other humans by the parameters of the assets they have and ignore other aspects of being human. This principle is the root of the world view of Homo Economicus. This study aims to criticize and refute the ideas and perspectives of Homo Economicus on human essence through the ideas of Muslim scholars about human nature. This research is a conceptual review of the literature using a normative descriptive method. The results of the study show that the emergence of Homo Economicus is caused because they adhere to the principle that views life only based on rationality and reason, whereas according to Islam this is not sufficient to be relied upon as the basis for the absolute truth of knowledge, because humans are entities that are manifested from the combination of body and spirit. , the second is what represents reason and al-nafsu
Kebebasan Beragama dalam Literatur Tafsir bi Al-Ma'tsur
Authors: Rozi Fathur
Published: February 2025

Beliefs (religion) are closely related to an individual's spiritual experience and cannot be imposed by anyone. The issue becomes different when the position of religion shifts from being private to entering the public sphere, making the choice of religion no longer an absolute fundamental right but subject to control, often leading to "threats" as religious conversion is considered a crime. Ultimately, practicing religion is no longer based on sincerity but rather coercion. In this study, the author limits the examination to the interpretation of bil ma'tsur written by three figures: Ibn Jarir al-Thabari, Abu al-Fida’ Ibn Kathir, and Jalaluddin al-Suyuti. The focus of the study is the tendency of bil ma'tsur interpretation in explaining verses about religious freedom related to theological categories in the religious tradition studied through literature review using content analysis techniques. The approach used is a comparative approach, aiming to portray the interpretations given by Thabari, Ibn Kathir, and al-Suyuti on verses about religious freedom. The research results show that there are four verses that share similarities in affirming the principle of religious freedom, emphasizing that every individual has the freedom to choose and believe in their religion. These four verses are Al-Baqarah verse 256, Yunus verse 99, Al-Kahfi verse 29, and Al-Kafirun verse 6. According to the views of al-Thabari, Ibn Kathir, and al-Suyuti, these verses convey an important message about respecting religious freedom and recognizing the right of every individual to choose their own beliefs, while emphasizing the values of truth and steadfastness in faith

Transforming agriculture: advancements in compost-biopolymers composites for enhanced sustainability
Authors: Ortega Yina , Salcedo Felipe
Published: February 2025

In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purposes. These composite materials utilize composted biosolids from the dairy industry as the main matrix (60%), blended with biodegradable polymers such as polybutylene adipate succinate (PBSA) and polylactic acid (PLA) as functional agents. This innovative approach contrasts with the prevailing literature on composite polymer materials, where polymers typically form the matrix and agricultural residues serve as fillers. Biosolids from Freskaleche S.A. undergo controlled thermal treatment and composting before being combined with PBSA and PLA polymers using an internal mixer. The development of these new compounds includes the evaluation of thermal stability, Fourier-transform infrared spectroscopy (FTIR), and mechanical properties. It is noteworthy that Compost/PBSA composites exhibit promising compatibility and thermomechanical properties resembling pure PBSA, suggesting their potential as thermoplastic materials for producing plastic-based agricultural products. Regarding Compost/PLA blends, compost enhances chemical reactions in PLA polymeric chains, significantly altering their thermomechanical properties. This research provides valuable insights into the use of biosolids for manufacturing composite materials, offering a sustainable approach to address agricultural challenges in the Cesar region.
Analysis of spiral mandrel dies with novel channel geometries to draw conclusions on the purging time of the melt using CFD
Authors: Vorjohann Felix , Schiffers Reinhard
Published: February 2025

Spiral mandrel dies are deeply integrated into the extrusion process and are the predominant die type for manufacturing products with a ring-shaped cross-section, e.g. blown film. The geometry of the axial spiral mandrel die is characterized by a spiral mandrel with one or more feed holes that merge into the spiral channels. The spiral channels themselves are embedded in the mandrel and have a characteristic u-shape in cross-section, which is dictated by the milling head used during manufacturing. In the past, numerous geometric parameters of the conventional axial spiral mandrel distributor have been examined in the course of optimizations, but the general design is still largely based on the concept of the 1960s. Therefore, this paper presents four concepts for new channel geometries that deviate from the conventional spiral channel cross-sectional shape. All variants were analyzed using a CFD-based algorithm for the automated geometry optimization by varying the general parameters describing the spiral channel. Other defining parameters were kept constant. The results provide insights into the influence of geometry parameters for spiral mandrel dies on purging time.
Thin films from modified Poly(glycolic acid) with excellent water vapor barrier
Authors: Hilhorst Marieke , Caliari Sara , Post Wouter , Kuijpers Lambertus J. , Alvarado Chacon Fresia
Published: February 2025

Commercial biodegradable polymers that combine high oxygen and water vapor barrier properties are scarce. In the packaging industry multilayer materials are usually used to achieve the barrier requirements, however they are usually not recyclable and will not biodegrade when discarded. The outstanding barrier properties of poly(glycolic acid) (PGA) make it an excellent candidate for a biodegradable oxygen and water vapor barrier packaging material. At the same time, its processability into films using standard converting equipment is a major challenge. Low melt strength, high processing temperatures, and fast crystallization at the die limit its use in conventional packaging applications. Chain extenders are typically used to improve the melt strength of polymers and thereby the overall processability, however they may affect the intrinsic barrier properties of the material. This work studied the reactivity of PGA with different chain extenders. It found that by using less than 2% reactive chain extenders the processability of PGA could be highly improved while keeping the intrinsic barrier properties of the material. After compounding PGA with the chain extenders Joncryl and carbodiimide, stable flat sheet extrusion of the material was possible resulting in sheets thinner than 10 μm. The multidirectional stretchability of the melt was improved, showing an increase in the melt strength of the polymer. Barrier properties were measured, and it was found that the water vapor transmission rate (WVTR) is not affected by the addition of the chain extender. This improvement in the processability of PGA offers a promising solution for biodegradable high-barrier packaging materials.
Design of an injection mold with local placement of heating coatings for warpage compensation
Authors: Hopmann Christian , Zimmermann Christoph , Fritsche Daniel C. , Bobzin Kirsten , Heinemann Hendrik , Erck Marvin , Lohrey Nicole
Published: February 2025

The influence of the thermal injection mold design crucially affects the geometric precision of injection molded parts. However, the adjustability of the heat flux distribution established with the conventionally used cooling channels is limited and cannot cover the vari able cooling demand. The proposed approach of using heating coatings on the cavity surface to manipulate the part’s cooling rate shows that it may be advantageous, due to the close and localized application to the part. A simulative optimization routine determines the necessary position and surface power of the heating coating. The objective of this methodology is to homogenize the surface temperature, inner cooling rate, and freeze time inside the part. This work applies the simulative design method for the optimized placement and heating power on a mold for a three-dimensional part. As the temperature field of the heating coating depends on the contacting, the electro-thermal simulation is analyzed and confirmed as sufficient to establish the optimal heat flux distribution. A process simulation study shows the dimension with the most critical warpage is decreased by 90%.
Material selection for injection molding hollow microneedles
Authors: Evens Tim , Vanwersch Pol , Castagne Sylvie , Van Bael Albert
Published: February 2025

Hollow microneedles are designed to perform intradermal medical substance delivery or fluid extraction, with polymers standing out as cost-effective materials for mass production via injection molding. However, existing research lacks a comparative analysis of different polymers in terms of processability and performance in skin penetration tests. This study addresses this gap by evaluating hollow microneedles fabricated from five biocompatible thermoplastic materials: polycarbonate (PC), polybutylene terephthalate (PBT), polylactic acid (PLA), polyamide 12 (PA12), and glass-fiber reinforced polyarylamide (PARA). Significant dif ferences in replication fidelity were found among the thermoplastics, with a higher calculated solidification time resulting in better replication fidelity due to extended deformability during the packing phase. PBT microneedles deformed during demolding and were excluded from penetration tests. Penetration tests on piglet ears showed no penetration for PA12 and PLA microneedles due to deformation of the needles. PARA demonstrated consistent penetration results, while PC exhibited an inconsistent penetration behavior, with some needles success fully penetrating while others deformed. High mechanical properties were found to be critical for achieving consistent and successful penetration.

Authors: Emrich Niclas , Rayer Moritz , Schiffers Reinhard
Published: February 2025

Filled epoxy potting materials are seen as promising polymer for applications in future automotive battery systems. Hence the electrolyte resistance is of crucial importance. This work examines the electrolyte resistance of potential material candidates for such applications. The material is stored hermetically in electrolyte for several weeks at an elevated temperature of 45°C. Swelling values are determined, and the mechanical behavior of the specimens is analyzed. Additionally, the electrolyte contamination is measured using head space injected gas chromatography and mass spectroscopy. Based on procedure of exclusion, the impact of filler- and matrix-system upon the swelling behavior is derived. The aim of this work is to identify possible amine-based epoxy materials, that are suitable for polymer metal joint applications, while being in contact with battery electrolytes.
Design Optimization of Rotationally Molded Hydrogen Pressure Vessels
Authors: Pritchard Alex , Martin Peter , McCourt Mark , Kearns Mark
Published: February 2025

Type IV hydrogen pressure vessels are made up of three components: a metallic boss, a polymer liner, and a composite overwrapping layer for reinforcement. Leakproof design of bosses is critical for safety, ensuring a gas-tight seal to prevent explosions due to leaks. Yet, their design has been largely overlooked. Using rotational molding it is possible to fully encap sulate bosses within liners during molding, but numerous challenges must be overcome relat ing to boss design for effective molding. FEA software was applied to virtually prototype boss designs and optimize their mechanical performance under pressure. CAD and FEA software were integrated in this work, enabling basic geometry constraints to be input in CAD, which were then fine-tuned in FEA in response to stress distribution results. This allowed the FEA model to optimize boss designs autonomously. To ensure moldability, initial boss designs were generated using existing rotational molding experience regarding the encapsulation of small inserts during molding. The autonomous optimization technique was then applied to minimize the boss weight by controlling the size of design features, while ensuring mechanical perfor mance constraints were met.

Published: February 2025

The aim of this case study is to identify the value added of existent biomass fibers (i.e., agro-industrial byproducts) and potential blends. The purpose is to explain the facts about sustainable and/or organic oil palm biomass in the energy recovery sector and in the biobased materials industry. Demand for sustainable biobased materials and energy recovery from biomass triggered the rapid growth experienced by the agricultural industry over recent years, leading to concerns about its impact on the environment and ecosystem. The agricultural industry is currently making efforts to improve sustainability practices, certifications, and to reduce carbon emissions based on innovative technologies. The used biomass, i.e. palm kernel shells (PKS), empty fruit bunches (EFB), and mesocarp fibers (MF), possesses widely accepted sustainability certifications for oil palm biomass, such as the Control Union certifications as a Roundtable on Sustainable Palm Oil (RSPO) approved certification body, the Regenerative Organic certification (ROC) for farms and products that meet the highest standards for soil health and biomass, and the EU Organic Certification in compliance with the standards and regulations of EC No. 834/2007 and EC No. 889/2008 on organic production of agricultural products. This work presents the main physicochemical characteristics of this studied biomass relevant to its energy recovery and a biobased material application. The characteristics of oil palm biomass can be summarized as a feedstock of medium energy content compared to fossil fuels and lower levels of sulfur, chlorine, and nitrogen than coal. Pellets of oil palm biomass are proven to meet expectations in both quality class A and B of non-woody pellets, i.e., characterized using the standards of solid biofuels, part 6, non-woody pellets, ISO 17225:2021. The application of biobased material ranges from pulp and paper to biobased polymer materials.

Authors: Garcia Aramendiz Johan Sebastián , Forero Varela Leonardo , Medina Perilla Jorge Alberto
Published: February 2025

Thermoplastic starches (TPS) are important bio-based, biodegradable polymers used in flexible packaging. However, their mechanical properties, processability, and high hydrophilicity limit their applications. This study examines the effects of chemical modifications and mechanical reinforcements on TPS matrices. Combinations of native and acetylated TPS, reinforced with native (CNF) and acetylated cellulose nanofibers (CNFA) at 1%, 2%, 3%, and 10%, were analyzed. TPS films were prepared with CNF using compression molding, followed by structural, morphological, mechanical, and hygroscopic analyses. Results show that higher CNF percentages increase tensile strength, slightly reduce moisture absorption, and decrease surface hydrophilicity. High material compatibility was observed, with proper phase interaction and mechanical homogeneity, especially at the highest fiber addition level. Further evaluation with higher acetylation degrees is needed to clarify the effects of this modification.

Therefore, opting for the more cost-effective acid is advisable
The effect of clays on the mechanical properties of dynamically revulcanized blends composed of ground tire rubber/high-density polyethylene
Authors: De Sousa Fabiula Danielli Bastos
Published: February 2025

This study examines the impact of adding Cloisite 20A and Halloysite clay on the mechanical properties of dynamically revulcanized blends composed of high-density polyethylene (HDPE) and ground tire rubber (GTR), which have been previously devulcanized via microwaves. Blends were prepared, containing different concentrations of the phases. Halloysite clay seems to have acted as a compatibilizer agent between the phases of the blends, whereas Cloisite 20A clay seems to have acted as a reinforcement in the revulcanized blends. However, slight deviations were noticed in the variations in the phases’ concentrations. This study explored the possibility of utilizing end-of-life tires in polymeric blends.

Bu sayede flüt pedagojisinde genişletilmiş tekniklerin rolü giderek daha önemli bir hale gelmiştir.
Flüt pedagojisinde genişletilmiş tekniklerin kazandırdığı yenilikler, flütistlerin teknik becerilerini geliştirirken, aynı zamanda müzikal ifadelerine özgünlük kazandırmaktadır. Bu teknikler, geleneksel çalma yöntemlerinin ötesine geçerek enstrümana ses aralığı ve tını açısından farklı olanaklar sunmaktadır. Bu olanakların, yaratıcı düşünme ve ifade zenginliği kazandırması ve eğitimde bu tekniklerin benimsenmesi, flütistlerin müzikal vizyonlarını da geliştirmektedir. Bu yenilikler sayesinde flütistler sadece performans kapasitelerini artırmakla kalmaz, aynı zamanda çağdaş müziğin yenilikçi yapısına daha bilinçli bir şekilde yaklaşırlar.
Bu makalenin amacı, genişletilmiş tekniklerin flüt pedagojisinde yarattığı yenilikleri inceleyerek, bu tekniklerin tanımını, türlerini ve flütistlere katkılarını değerlendirmek; ayrıca çağdaş flüt repertuvarındaki yeniliklerin eğitimdeki katkısının pedagojik gelişmelerini ortaya koymaktır.

When the soil fertility is inadequate, it leads to low productivity, which results to one of the factors hindering crop production in Nigeria. It has been attributed to planting of crop consistently without adequate artificial soil nutrient of farm inputs. However, the combination of chemical fertilizer and organic manure is regarded as one of solution to the problem. The treatment consists of NPK fertilizer with fresh weight of maize, NPK with dry weight of maize and NPK with seed yield maize. The factorial ANOVAL model is adopted for the analysis. The result indicates that Fcal(10.57) > Ftab(0.83) for the poultry manure and Fcal(1.54) > Ftab(0.83) for NPK Fertilizer, means that both contributes to the fresh plant weight of the maize, while Fcal(16.06) > Ftab(0.83) for poultry manure and Fcal(3.05) > Ftab(0.83) for NPK fertilizer respectively have a significance difference by contributing positively to plant seed yield of maize. Also, Fcal(0.308) < Ftab(0.83) for poultry manure and Fcal(0.135) < Ftab(0.83) for NPK fertilizer implies that there is no significance difference to dry plant weight. It shows that poultry manure and NPK fertilizer equally contributed significantly to the fresh plant weight of the maize and plant seed yield of the maize but does not contribute positively to the dry plant weight.

Published: February 2025

This study examines the purchase intentions of university students regarding iOS (Apple) and Huawei smartphones, delving into the factors shaping their preferences. Using a structured survey, data was collected on students' demographic profiles, current smartphone usage, satisfaction levels, brand perceptions, and key decision-making criteria. The survey also explored the influence of social circles, brand loyalty, and the appeal of promotional offers, alongside attitudes toward technological advancements like 5G connectivity. The findings highlight distinct patterns of brand preference and their underlying drivers. Apple (iOS) smartphones were associated with a strong brand image, premium features, and perceived reliability, while Huawei gained recognition for competitive pricing and advanced technological offerings. Price sensitivity emerged as a critical factor, yet features like battery life, design aesthetics, and camera quality also heavily influenced decisions. Additionally, social influences, including recommendations from friends and family, were pivotal in shaping purchase intentions. Notably, students who favored iOS cited ecosystem integration as a key motivator, while Huawei users prioritized innovation and affordability. The study reveals that promotional offers significantly impact purchase likelihood, with a marked preference for 5G-enabled devices. Insights into brand loyalty underscore the importance of customer service and after-sales support, with a notable openness among students to switch brands if incentivized by better features or pricing. These findings provide valuable implications for smartphone manufacturers to tailor their marketing strategies and product offerings to meet the evolving preferences of university students, fostering greater engagement and brand affinity.

How corporate social responsibility reporting affects financial performance? Evidence from Saudi Arabia
Authors: Rahma Driss  , Emna Jaballah
Published: February 2025

This study examines the relationship between CSR disclosures and the performance of Saudi Arabian companies. It analyzes the annual financial reports of 90 non financial companies listed on the Saudi Stock Exchange (Tadawul) from 2019 to 2023. Using content analysis software, the study evaluates the quality of financial reports and identifies the extent of philanthropic, environmental, and social related disclosures. Subsequently, the impact of philanthropic, environmental, and social disclosures on key performance indicators, such as return on assets (ROA) and return on equity (ROE), is assessed. A CSR disclosure list was developed through a principal content analysis of the annual financial reports. The findings reveal a significant positive relationship between CSR disclosure and corporate performance metrics across all models. These results align with stakeholder and signaling theories, suggesting that robust CSR practices enhance financial performance and serve as credible signals to stakeholders. Notably, sector specific variations were identified, with non manufacturing firms exhibiting stronger positive correlations between CSR disclosures and performance measures compared to manufacturing firms. Additionally, firm characteristics such as size were found to significantly influence the CSR performance relationship. This research contributes to the expanding body of literature on CSR and corporate performance in emerging markets. It offers valuable insights for policymakers, investors, and corporate leaders navigating the evolving sustainable business landscape in Saudi Arabia. The findings underscore the pivotal role of CSR disclosure in fostering sustainable and responsible business practices in the region.
