Catalytic Dehydrogenation on Ultradisperse Sn-Promoted Ir Catalysts Supported on MgAl2O4 Prepared by Different Techniques
Authors: de Miguel Sergio , Fals Jayson , Benitez Viviana , Especel Catherine , Epron Florence , Bocanegra Sonia
Published: June 2024

Ir and IrSn catalysts with different Sn contents (0.5, 0.7 and 0.9 wt%) were prepared using MgAl2O4 supports synthesized using two different techniques (the citrate–nitrate combustion and coprecipitation methods). Both supports, with a spinel structure, presented low acidity and good textural properties. However, the support prepared by coprecipitation had higher specific surface area and pore volume than the one prepared by combustion, which would favor the dispersion of the metals to be deposited. Likewise, during the preparation of the catalytic materials, a very good interaction was achieved between the metals and both supports, which was confirmed by the presence of sub-nanometer atomic clusters in the mono- and bimetallic catalysts. Regarding the catalytic properties, while the monometallic Ir/MgAl2O4 samples lead to a very low conversion of n-butane and a selectivity towards hydrogenolysis products, the addition of Sn to Ir increases the conversion, decreases hydrogenolysis and therefore sharply increases the selectivity towards the different butenes. Catalysts with higher Sn loadings present better catalytic behavior. One of the roles of the Sn promoter would be to geometrically modify the Ir clusters, drastically decreasing the hydrogenolytic activity. This effect, added to the strong electronic modification of the Ir sites by the action of Sn, with probable Ir-Sn alloy formation, is responsible for the high catalytic performance of these bimetallic catalysts.

Published: June 2024

Fault structures can cause a bad mining environment and increase the stress of surrounding coal pillar faults. The study investigates the stress evolution characteristics within fault structure groups and their surrounding coal pillars and explores the extent to which these fault structure groups influence the stress distribution in coal pillars. Based on three-dimensional modeling technology, a transparent geological model of the geological environment of fault structure groups was constructed and finite difference software was used to generate a numerical simulation model. Two survey lines and four survey points were arranged to analyze the stress distribution of a coal pillar fault. The results show that the fault structure groups have obvious stress barrier effects. There is a 35 m stress reduction zone in the hanging wall of the fault and a 30 m stress increase zone in the footwall of the fault. Both FL-1 and FL-3 faults have a stress barrier effect in the hanging wall. The obvious stress increases in the footwall of the fault are 37.7 MPa and 33.5 MPa, respectively. The stress of the FL-2 fault as a whole appears to be a more obvious superposition at the end of mining, and the peak stress reaches 41.5 MPa.
Optimal Design of a Renewable-Energy-Driven Integrated Cooling–Freshwater Cogeneration System
Authors: Janghorban Esfahani Iman , Ifaei Pouya
Published: June 2024

This study presents a novel approach that will address escalating demands for water and cooling in regions vulnerable to climate change through the proposal of an optimal integrated cooling–freshwater cogeneration system powered by renewable energy sources. Comprising three subsystems (integrated multi-effect evaporation distillation, absorption heat pump, and vapor compression refrigeration (MAV); renewable energy unit incorporating solar panels, wind turbines, batteries, and hydrogen facilities (RHP/BH); and combined heat and power (CHP)), the system aims to produce both cooling and freshwater. By recovering cooling from combined desalination and refrigeration subsystems to chill the air taken into the gas turbine compressor, the system maximizes efficiency. Through the recovery of waste heat and employing an integrated thermo-environ-economic framework, a novel objective function, termed modified total annual cost (MTAC), is introduced for optimization. Using a genetic algorithm, parametric iterative optimization minimizes the MTAC. The results reveal that under optimum conditions, the MAV, RHP/BH, and CHP subsystems account for 67%, 58%, and 100% of total annual, exergy destruction, and environmental costs, respectively. Notably, the system exhibits lower sensitivity to fuel prices than renewable energy sources, suggesting a need for future research that will incorporate dynamic product prices and greater fuel consumption to produce enhanced operational robustness.
Varieties of Revelation, Varieties of Truth—A Comparative Ontological Study of Revelation through Music and Sciences
Authors: Ertüngealp Alpaslan
Published: June 2024

Accounts of revelation and contemporary views of these are based on beliefs and historical citations. These accounts shall not be limited to the understanding and interpreting of historical and other events within writings but must present the possibility of an objective analysis of the nature of revelation as a phenomenon, an object of our sensory and mental conscious experiences. This paper approaches the act or phenomenon of revelation regardless of the revealer and its nature. Can we abstract the revealer and the revealed from revelation and have an ontological account of revelation solely focusing on the occurrence itself? The central part of the discussion is based on the object/property pair as ontological categories through which the means are analyzed. A comparative method is used where Scripture, musical writings, and mathematical/physical formulae (as potential means of revelation) are scrutinized. As a result, without any need to determine the revealer, revelation can be based on and described through pure properties (not tropes) in human experience, intellect, and understanding. The possibility of revelation beyond Scripture and Jesus Christ—following a type of liberal and general theory of revelation—presents itself in arts and sciences. The “true” of a musical work, when found and experienced during musical performances and scientific truths represented by the formulae, which describe the world and a meta domain, can be derived from the chains of signs and symbols as it is through Scripture. Human cognitive faculties present a universal natural limit to our direct experiencing of the transcendent, of the supernatural. A new dualist conception of logos as a metaphysical category marks the domain bridging the non-transcendent with the transcendent.

Authors: Gupta Anunay , Dey Arup , Lee Chiwon W. , Yodo Nita
Published: June 2024

The use of biodegradable paper pulp pots has been gaining traction, especially among environmentally conscious consumers and horticultural practitioners who prioritize sustainability. The choice between paper pulp and polyethylene nursery pots in horticultural practices is a complex decision, involving considerations such as environmental impact, cost-effectiveness, durability, and overall sustainability. This study aims to provide practical insights into the comparative performance of paper pulp and polyethylene pots, specifically in terms of plant health, degradation, and techno-economic considerations. The study involved the growth performance assessment of four plant species, Cannonball Tomato, Celebrity Tomato, Parris Island Lettuce, and French Marigold, in a greenhouse experiment setup. Additionally, a degradation analysis was conducted to determine the average degradation rate and pattern. Finally, a techno-economic analysis compared the value of plant health and degradation with the market price. By evaluating the quality performance aspects of paper pulp pots, this study not only provides valuable insights but also identifies potential areas of improvement for other biodegradable pots, thereby contributing to the ongoing efforts to promote sustainable horticultural practices.
Progressing toward Teal Organizations: An Assessment of Organizational Innovation in the Spanish Public Administrations
Authors: Gómez Muñoz Carlos F. , Moreno Romero Ana
Published: June 2024

Organizational innovation can be a promising path for public administrations to follow to become more supportive of the realization of sustainability goals. With the Teal Organizations framework as a reference, this study explores organizational innovation in Spanish public administrations by assessing the extent and patterns of the implementation of selected innovative organizational practices, with the aim to help them improve. This study performs multivariate and individual analyses of the variance and factor analysis of the responses given by Spanish public sector employees to an online questionnaire about the degree of implementation of certain practices in their organization. The results show that there are little differences in the degree of implementation of these practices among the national, regional, and local administrations and that this implementation does not seem to be guided by the three principles of Teal Organizations: self-management, wholeness, and evolutionary purpose, but by five factors combining them, labeled as trust, task assignment, meetings management, hierarchy, and community and values. Because of the low degree of implementation of the practices under the community and values factor and the comparatively low effort required to introduce them, these practices appear as interesting options to explore when considering administrative reforms.
The Best of Both Worlds: How Financial Growth Can Engender Improved Sustainability for Businesses
Authors: Mutambik Ibrahim , Almuqrin Abdullah
Published: June 2024

In recent decades, the increasingly competitive marketplace that has resulted from factors such as globalization and technological innovation has made it ever harder for businesses to deliver economic sustainability. At the same time, the pressure on businesses to achieve and maintain environmental sustainability has also grown significantly. This study examines the factors that influence economic sustainability, the relationship of economic sustainability to environmental sustainability, and the extent to which these two factors ultimately affect financial growth. In order to achieve this, this study analyses the results of 342 questionnaires completed by managers of manufacturing companies within Saudi Arabia’s small and medium enterprises (SMEs) sector. This analysis, using structural equation modeling, showed that innovation inclination, customer centricity, supplier relationships, network maturity, and strategic agility all have significant effects on economic sustainability. This study also shows that economic sustainability has a significant impact on environmental sustainability and that economic sustainability and environmental sustainability positively impact financial growth. This study adds to the current literature by demonstrating an explicit association of innovation inclination, customer centricity, supplier relationships, network maturity, and strategic agility with economic sustainability, as well as a positive relationship between economic sustainability and environmental sustainability. The findings also contribute to the literature by showing the direct impact of both economic sustainability and environmental sustainability on financial growth. In practical terms, this study will help Saudi SMEs develop business strategies that drive both environmental and business performance and provide useful insights for Saudi policymakers and financial institutions looking to support the Saudi Vision 2030 aims by encouraging funding and support mechanisms that drive better business and environmental performance.

Authors: Jalali Hossein , Keynia Farshid , Amirteimoury Faezeh , Heydari Azim
Published: June 2024

In the contemporary era, global air quality has been adversely affected by technological progress, urban development, population expansion, and the proliferation of industries and power plants. Recognizing the urgency of addressing air pollution consequences, the prediction of the concentration levels of air pollutants has become crucial. This study focuses on the short-term prediction of nitrogen dioxide (NO2) and sulfur dioxide (SO2), prominent air pollutants emitted by the Kerman Combined Cycle Power Plant, from May to September 2019. The proposed method utilizes a new two-step feature selection (FS) process, a hybrid neural network (HNN), and the Coot optimization algorithm (COOT). This combination of FS and COOT selects the most relevant input features while eliminating redundant ones, leading to improved prediction accuracy. The application of HNN for training further enhances the accuracy significantly. To assess the model’s performance, two datasets, including real data from two different parts of Combined Cycle Power Plant in Kerman, Iran, from 1 May 2019 to 30 September 2019 (namely dataset A and B), are utilized. Subsequently, mean square error (MSE), mean absolute error (MAE), root mean square deviation (RMSE), and mean absolute percentage error (MAPE) were employed to obtain the accuracy of FS-HNN-COOT. Experimental results showed MSE of FS-HNN-COOT for NO2 ranged from 0.002 to 0.005, MAE from 0.016 to 0.0492, RMSE from 0.0142 to 0.0736, and MAEP from 4.21% to 8.69%. Also, MSE, MAE, RMSE, and MAPE ranged from 0.0001 to 0.0137, 0.0108 to 0.0908, 0.0137 to 0.1173, and 9.03% to 15.93%, respectively, for SO2.
Decarbonization Drivers and Their Impact on Business Models in the Energy-Intensive Manufacturing Industry (EIMI)
Authors: Mais Franziska , Bauernhansl Thomas
Published: June 2024

EIMIs face the challenge of adapting to the Paris Agreement and the European Green Deal to achieve carbon neutrality. Driven by consumer interest in low-carbon products, regulatory requirements, and investor priorities, companies are pressured to integrate sustainability beyond short-term financial gains. The growing awareness of the environmental impact of business models (BM) has fueled the development of Sustainable Business Models (SBMs). Although the importance of decarbonization of EIMIs has increased, there is a lack of industry-specific research examining the combination of decarbonization and business models, as well as their interrelationships and correlations. This study addresses the discussion on the role of SBMs in decarbonization, improving the understanding of how these drivers can be integrated to enable new BMs for EIMIs. Based on a structured literature review and semi-structured interviews within the EIMIs, the study identifies BM components influenced by these drivers requiring sustainable business model innovation (SBMI). Results show that decarbonization drivers significantly impact all BM components. Experts emphasize the importance of collaborative approaches and cooperation throughout the value chain. This research highlights the need for systematic analysis to understand how companies can manage decarbonization drivers effectively and suggests exploring potential SBM design options.
The Influence of the Interface on the Micromechanical Behavior of Unidirectional Fiber-Reinforced Ceramic Matrix Composites: An Analysis Based on the Periodic Symmetric Boundary Conditions
Authors: Yan Wei , Shi Shilun , Xiao Longcheng , Li Xiulun , Xu Jian
Published: June 2024

The long-term periodicity and uncontrollable interface properties during the preparation process for silicon carbide fiber reinforced silicon carbide-based composites (SiCf/SiC CMC) make it difficult to thoroughly investigate their mechanical damage behavior under complex loading conditions. To delve deeper into the influence of the interface strength and toughness on the mechanical response of microscopic representative volume element (RVE) models under complex loading conditions, in this work, based on numerical simulation methods, a microscale representative volume element (RVE) with periodic symmetric boundary conditions for the material is constructed. The phase-field fracture theory and cohesive zone model are coupled to capture the brittle cracking of the matrix and the debonding behavior at the fiber/matrix interface. Simulation analysis is conducted for tensile, compressive, and shear loading as well as combined loading, and the validity of the model is verified based on the Chamis theory. Further investigation is conducted into the mechanical response behavior of the microscale RVE model under complex loading conditions in relation to the interface strength and interface toughness. The results indicate that under uniaxial loading, increasing the interface strength leads to a tighter bond between the fiber and matrix, suppressing crack initiation and propagation, and significantly increasing the material’s fracture strength. However, compared to the transverse compressive strength, increasing the interface strength does not continuously enhance the strength under other loading conditions. Meanwhile, under the condition of strong interface strength of 400 MPa, an increase in the interface toughness significantly increases the transverse compressive strength of the material. When it increases from 2 J/m2 to 20 J/m2, the transverse compressive strength increases by 28.49%. Under biaxial combined loading, increasing the interface strength significantly widens the failure envelope space under σ2-τ23 combined loading; with the transition from transverse compressive stress to tensile stress, the transverse shear strength shows a trend of first increasing and then decreasing, and when the ratio of transverse shear displacement to transverse tensile/compressive displacement is −1, it reaches the maximum. This study provides strong numerical support for the investigation of the interface properties and mechanical behavior of SiCf/SiC composites under complex loading conditions, offering important references for engineering design and material performance optimization.

Published: June 2024

This paper considers a nonlinear fractional-order boundary value problem  HDa,gα1,β,μx(t)+f(t,x(t),HDa,gα2,β,μx(t))=0, for t∈[a,b], α1∈(1,2], α2∈(0,1], β∈[0,1] with appropriate integral boundary conditions on the Hölder spaces. Here, f is a real-valued function that satisfies the Hölder condition, and  HDa,gα,β,μ represents the tempered-Hilfer fractional derivative of order α>0 with parameter μ∈R+ and type β∈[0,1]. The corresponding integral problem is introduced in the study of this issue. This paper addresses a fundamental issue in the field, namely the circumstances under which differential and integral problems are equivalent. This approach enables the study of differential problems using integral operators. In order to achieve this, tempered fractional calculus and the equivalence problem of the studied problems are introduced and studied. The selection of an appropriate function space is of fundamental importance. This paper investigates the applicability of these operators on Hölder spaces and provides a comprehensive rationale for this choice.

Authors: Vuksinic Evelyn , Miguel Roberto Esteban , Aldaya Maite M. , Rodriguez Corina Iris
Published: June 2024

Argentina stands as the leading producer and exporter of olive products in the Americas, with the province of La Rioja as its main productive area. Since the 1990s, the olive grove cultivated area and related agro-industry in La Rioja have expanded. However, the resulting wastewater has generally been neglected. The water footprint (WF) provides information about the water volume consumed and polluted by a production process. Since the 1990s, agricultural and agro-industrial activities in La Rioja have experienced substantial growth. This study aims to analyze the generation, quality, and management of Oil Mill Wastewater (OMWW) using the grey WF of chloride and nitrate as an indicator and focusing on two olive mills (OM) in La Rioja. Additionally, it seeks to examine the relationship between the international trade of provincial olive oil and the estimated grey WF. For the diagnosis of OMWW generation, a description of the production process was made coupled with flow and physico-chemical characterization. The total grey WF was 8.69 and 45.5 L water/L olive oil for OM 1 and OM 2, respectively. Nitrate was identified as the critical pollutant. The grey virtual water export related to the export of olive oil was 5569 m3 for OM 1 and 28,000 m3 for OM 2. The provincial grey virtual water export related to olive oil was 161,955 m3 with major trade destinations including Spain, the United States, and Brazil. The article analyses for the first time the grey WF of olive oil industries and assess the related grey virtual water exports. This research represents a step forward in the knowledge of wastewater management in the olive oil sector and facilitates the search for solutions to minimize negative environmental impacts while promoting cleaner production.
A Modified Manning’s Equation for Estimating Flow Rate in Grass Swales under Low Inflow Rate Conditions
Authors: Wang Jianlong , Qiu Rongting , Xia Xu , Li Xiaoning , Zhang Changhe , Wang Wenhai
Published: June 2024

As green infrastructure has evolved, grass swales have become integral components of stormwater management. Manning’s equation is commonly used to describe the hydraulic characteristics of grass swales. However, due to flow loss from infiltration, grass swales often deviate from the assumptions of Manning’s equation, potentially leading to significant errors in grass swale flow rate calculations. In this study, we systematically investigated changes in flow rates in grass swales under various constant inflow rate conditions. The results indicated that the suitability of using Manning’s equation to estimate flow rate in grass swales varies with inflow rate. At an inflow rate of 3.00 m3/h, the discrepancy between the measured and the estimated flow rates by Manning’s equation was the smallest, ranging from −0.24 to 0.19 m3/h. At lower inflow rates (1.00 to 2.00 m3/h), Manning’s equation underestimated the flow rates by 0.16 to 0.47 m3/h; at higher rates (4.00 m3/h), it overestimated the flow rates by 0.01 to 0.61 m3/h. Considering infiltration losses as the primary cause of these errors, we proposed an improved Darcy’s formula for estimating the infiltration rates in grass swales, along with a modified Manning’s equation for more accurate flow rate calculations. The modified Manning’s equation provides enhanced accuracy in calculating flow rates in grass swales compared to the traditional version.

Published: June 2024

This study discusses some aspects of environmental reconstruction through the palynological analysis of soil samples recovered from archaeological contexts belonging to the Iron Age at Sâncrai-Darvas. The microscopic fossils included in this study are pollen, fungal spores, microscopic charcoal and eggs of intestinal parasites. Pollen taxa were divided into categories of different types of land cover and land-use, while fungal spores were classified between coprophilous (fungi that grow on animal dung) and plant pathogens (parasitic/smut fungi). Intestinal parasites include two species infecting both humans and animals: roundworm and tapeworm. The abundance of microcharcoal particles suggests both regional biomasses burning in association with climate conditions, as well as in situ fires depending on the archaeological context (e.g. cremation). The overall palynological aspects suggest mixed agro-pastoral practices throughout the different archaeological horizons.

تتناول هذه الدراسة الفروق الدلالية بين مفردتي (الكُره) (والكَره)، بضمّ الكاف وبفتحها، لبيان الفرق الدلالي الدقيق بين المفردتين، في اللغة وفي السياق القرآني؛ لإظهار تميّز القرآن في استعمال المفردات، ويتجلّى بذلك إعجاز القرآن في اختيار المفردة، وبالتالي؛ فإن مشكلة الدراسة قائمة على محاولة إيجاد الفرق الدلالي الدقيق بين المفردتين، وتهدف الدراسة بناء على ذلك - إلى إيجاد الفرق الدقيق بين المفردتين من خلال الرجوع إلى الأصل اللغوي الذي ترجع له المفردتان، وبيان الدلالات الصرفية المترتبة على اشتقاق المفردتين، ومن ثمّ البحث في الدلالة السياقية للمفردتين في سياقاتها القرآنية، وبذلك نكتشف الفرق الدقيق بينهما. وتكمنُ أهمية الدراسة في إفادتها لطلبة العلم المُهتمين بدراسة الفروق الدلالية بين المفردات القرآنية، وكونها إضافة علمية في حقل الدراسات المهتمة، والمعتنية بالفروق الدلالية بين المفردات القرآنية. واقتضت طبيعة الدراسة أن نسلُك فيها المنهج الاستقرائي؛ وذلك باستقراء المعاجم والسياقات، والمنهج التحليلي؛ وذلك بتحليل الفروق اللغوية بين المفردتين، عبر تحليل سياقاتها، للوصول إلى طبيعة استعمال القرآن لكلّ منهما. ومن أبرز النتائج التي توصلت إليها الدراسة: انتفاء الترادف بين المفردات التي يُظن بها الترادف، فلا تحلُّ إحداهما محلَّ الأخرى، بل لكل واحدة موقعها ودلالتها واستعمالها الخاص الذي تفرّدت به عن الأخرى. وظهر الفرق الدقيق بين المفردتين من خلال الكلمات المتقابلة، فالكُره مضادُ المحبة، والكَرهُ مضادُ الطوع. وعليه: يوصي الباحثان بإكمال مسيرة البحث في الفروق الدلالية بين المفردات، وبخاصة تلك التي قد يُظَنُّ بها الترادف؛ لبيان أن كل لفظ وكل حركة جاءت تؤدي دلالةً لا تُؤدَّى إلا بها، وذلك يفتح للمتلقي أبواباً جديدة في فهم آيات الكتاب، فيبقى على يقينٍ بأنه كتابٌ مُعجزٌ رباني.
نشأة وتطور مباحث الحكم الوضعي في التدوين الأصولي الحنفي دراسة استقرائية تحليلية
Authors: الصواغ عبد الرحمن صباح
Published: June 2024

تتمثل فكرة البحث في بيان نشأة وتطور مباحث الحكم الوضعي في المصنفات الأصولية الحنفية. وتكمن أهميتها في الكشف عن المسار التاريخي الذي سلكته هذه المباحث في النظرية الأصولية عبر أطوارها المتتالية، ومن ثمّ الكشف عن مكانتها، والسؤالات التي أثارتها. وقد نشأت إشكالية الدراسة عن التساؤل الآتي: كيف نشأت مباحث الحكم الوضعي وتطورت عبر تاريخ التدوين الأصولي الحنفي؟ وتعززت هذه الإشكالية بعدم تصدي البحث الأصولي المعاصر لها؛ بل وندرة الدراسات في هذا الاتجاه عمومًا. وعليه سعت الدراسة عبر تبنّيها المنهج الاستقرائي التحليلي إلى استقراء مباحث الحكم الوضعي في المصنفات الحنفية، ثم تحليلها من جهتي الترتيب الشكلي والتناول الموضوعي، ثم تتبّع أثر اتصال متأخري الأحناف بالطريقة الكلامية على هاتين الدلالتين. وخلصت الدراسة – في أهم نتائجها– إلى أنّ غرض تحقيق مفهوم العلة في باب القياس وتمييزه عن غيره كان دافعا إلى البحث في سائر الأحكام الوضعية المشتبهة بها، تاركا أثره في صياغة مفاهيمها وصناعة تقاسيمها، لا سيما على يد الدبوسي ثم البزدوي والسرخسي، وما زال الأمر على هذا المنوال إلى أن اتصل متأخرو الأحناف بالطريقة الكلامية، فانتقلت مباحث الحكم الوضعي – إثر بروز نظرية الحكم الشرعي عند الغزالي - من مستوى التناول التبعي في آخر باب القياس إلى مستوى التناول الأصلي: باعتبارها قسيمًا للحكم التكليفي أولًا، ثم بإدراجها ضمن المبادئ اللازمة لتسديد التصور في صدارة المصنفات الأصولية؛ لذا يرى الباحث أنّ استمرار العناية بالمسارات التاريخية التي سلكها البحث الأصولي كفيلٌ بالإبانة عن التساؤلات التي كانت تشغله، وعن طرائقه في الإجابة عنها. وأنّ من أهم الدَّوال المُنتِجة في هذا الميدان هو التساؤل: ما الغاية التي توخّاها الأصوليون من إيراد هذا المبحث أو ذاك؟
دور الجمعيات الخيرية في تحقيق التنمية المستدامة “الجمعية الكويتية للعمل الإنساني أنموذجًا”
Authors: القادري مزنة عدنان
Published: June 2024

الفكرة الرئيسية للبحث هي توضيح الدور الفعال للجمعيات والمؤسسات الخيرية في تحقيق التنمية المستدامة بأبعادها المختلفة، وتبرز أهمية البحث في عنايته بقضية دولية تزايد الاهتمام تجاهها وهي التنمية المستدامة، والتنبيه على مواكبة الدين الإسلامي لقضايا العصر، بالإضافة إلى تسليط الضوء على مكانة الجمعيات الخيرية ودورها الاقتصادي والمجتمعي، فهي تعد جزءاً من الاقتصاد الاجتماعي الذي هو سابع أكبر اقتصاد في العالم بما يقدر بنحو 2.2 ترليون دولار أمريكي، وتتمثل مشكلة البحث في توسيع دائرة أنشطة الجمعيات الخيرية وتطوير أساليبها، من خلال استغلال الموارد التي لديها لتحقيق التنمية المستدامة بمجالاتها المتعددة، ويهدف البحث إلى تسليط الضوء على نماذج مبتكرة لمشاريع خيرية تساهم في تحقيق التنمية المستدامة بأبعادها الثلاثة، وذلك من خلال توضيح بعض التجارب الحديثة الناجحة التي قامت بها الجمعية الكويتية للعمل الإنساني كأنموذج تستنير به بقية الجمعيات والمؤسسات الخيرية، ولهذا استخدم الباحث المنهج الوصفي القائم على الاستقراء والتحليل، والمنهج الاستكشافي الاسترشادي، وتمثلت أبرز نتائج البحث في أن النظام الاقتصادي الإسلامي يدعو إلى تحقيق التنمية المستدامة بأبعادها الثلاث من خلال رؤيته التنموية، بل ويضيف لها البعد الروحي، وأن للاجتهاد الفقهي المعاصر دور في توسيع أنشطة الجمعيات والمؤسسات الخيرية، كما أن الجمعية الكويتية للعمل الإنساني تعتبر أنموذجاً مبتكراً في صناعة العمل الخيري متمثلة بمشاريعها الخيرية التي تحقق التنمية الاجتماعية المستدامة والتنمية الاقتصادية المستدامة والتنمية البيئية المستدامة، لذلك يرى الباحث أن الحاجة ماسة لتفعيل دور الجمعيات والمؤسسات الخيرية في تحقيق التنمية المستدامة بأبعادها المختلفة، من خلال إطلاق مشاريع خيرية مستدامة، وتكثيف الجهود لابتكار أدوات ومشاريع خيرية جديدة تسد حاجة المستفيدين وتقلل من اعتمادهم على المساعدات العينية والمادية بشكل مستمر، بما ينهض بالدول والمجتمعات الإسلامية.
الهجرة في ظلال القرآن بين الواقع والمأمول
Authors: ابو عمرة فايز حسان
Published: June 2024

فكرة البحث بيان موضوع الهجرة في ظلال القران الكريم بين الواقع والمأمول. وتكمن أهمية البحث في بيان حال المسلمين اليوم من تهجير، واضطهاد، وقتل، كذلك بيان الأحكام الشرعية في الهجرة، كذلك بيان الآثار المترتبة على الهجرة غير الشرعية. وتتمثل إشكالية البحث في: ما دوافع الهجرة الشرعية وغير الشرعية؟ وما الآثار المترتبة على الهجرة؟ ويهدف البحث إلى بيان حال المسلمين اليوم من تهجير واضطهاد وقتل، ويهدف إلى بيان ملكية الأرض، ويهدف إلى بيان حال المسلمين في الهجرة على عهد النبي صلى الله عليه وسلم، وفرارهم بدينهم، بخلاف أحوال المسلمين اليوم فغالب هجرتهم تكون من طغيان بعض الحكام، ومن الوضع الاقتصادي المتردي. واتبع الباحث المنهج الاستقرائي. وتوصلت الدراسة إلى أبرز النتائج: ومنها أن كثيرًا من شباب المسلمين الذين يهاجرون إلى بلاد الغرب لا يبالون بأي الأعمال يقومون بها بهدف الكسب المادي حتى وإن كانت مخالفة لشرعنا الحنيف، ودافع الهجرة عند بعض الشباب والأسر سببه الفقر، أو انعدام الأمن، أو الرغبة في الترف الزائد عن الحد، وكفل الإسلام في الهجرة الشرعية حق الحياة، وحق الأمن، والعدل، والمساواة، وصون كرامة الإنسان، واحترام آدميته للعيش بكرامة. والتي لا يخشى على دينه من ذاك البلد، والضرر الحاصل الهجرة غير الشرعية يؤدي إلى انتشار الفساد في البلاد، وتعريض أمن الوطن والمواطن بأسره إلى خطر كبير. وتوصي الدراسة: بالعمل على تطوير سوق العمل في البلدان الفقيرة حتى يَفْتَحَ مجالٌ للعمالة فتنعدم فكرة الهجرة عند جيل الشباب، وهذا يحتاج إلى دعم متواصل من الدول الغنية إلى تلك البلدان.

Published: June 2024

Background:
Renal calculi, commonly known as kidney stones, is a prevalent urological condition that affects a substantial portion of the population worldwide. The formation of kidney stones is a complex process influenced by various factors, including diet, fluid intake, genetics, and metabolic abnormalities. The pathogenesis of renal calculi involves a complex interplay of multiple factors, including supersaturation of urine with stone-forming constituents, urinary supersaturation, crystallization, and aggregation.
Objective:
This review aims to provide an overview of the present understanding of renal calculi, their pathophysiology, diagnostic approaches, and available treatment modalities.
Methods:
This review discusses the different types of kidney stones, such as calcium oxalate, calcium phosphate, uric acid, and struvite stones, and explores their formation mechanisms and associated risk factors. The management of renal calculi relies on stone characteristics, patient symptoms, stone size, and location. Furthermore, counseling and education regarding lifestyle modifications and risk factor management are essential for long-term management.
Conclusion:
Accurate diagnosis and appropriate management based on stone characteristics and patient symptoms are essential for successful outcomes. Preventive strategies to reduce stone recurrence are vital for long-term management and patient well-being. However, further research is needed to refine diagnostic techniques, improve treatment options, and enhance the understanding of the underlying pathophysiology of renal calculi.
Aspects of Loco-Description in J. M. Coetzee’s Disgrace
Authors: Frederick Suresh , Benito Sam B
Published: June 2024

The term “topography” describes a landscape’s structural elements and how they interact with the surrounding area. It focuses on the connections between the natural and constructed ecosystems and how human activities affect the environment. The history and ecological health of a region can be inferred from its topography. For instance, a location’s topography may reveal whether it has seen erosion, deforestation, or other types of ecological disturbance. Ecologists can better understand how environmental changes affect the landscape and its inhabitants by studying the topography of a certain location. John Maxwell Coetzee was a famous South African writer who tells us about these landscapes, climates, and other ecological aspects flawlessly in his novel Disgrace. John Maxwell Coetzee was popularly known by his initials, J.M. Coetzee. Coetzee was born on February 9, 1940, in Cape Town, South Africa. This paper studies the aspects of loco-description in J.M. Coetzee’s Disgrace.
Exploring Iroquois Culture in Joseph Bruchac’s Peacemaker: A Framework for Ethical Decision-Making Rooted in Core Character Value
Authors: Sam Daniel K , Shanthi K
Published: June 2024

Ethical decision-making is deeply intertwined with the foundational cultural values that articulate and embody core character virtues. These values find expression through moral and virtuous principles, shaped by social and cultural constructs, thereby guiding community behaviour. In the realm of environmental ethics, culture significantly influences the placement of the non-human world within various spectra, be it at the pinnacle, bottom, or as equals. Trustworthiness, respect, responsibility, and caring, the core character values, are intrinsically linked to where the non-human world stands in this context. Joseph Bruchac, a revered Native American author, revisits the historical genesis of the Iroquois confederacy, shedding light on the intricate relationship between the human and non-human worlds in his novel, Peacemaker. This paper delves into comprehending the Iroquois culture as a foundation for ethical decision-making, with a specific focus on core character values such as trustworthiness, respect, responsibility, and caring.
The Wave of the Future: Cognizance of the Environmental Insubstantiality in the Face of Human Intrusion in Margaret Atwood’s Oryx and Crake, and The Year of The Flood

A fragile environment is prone to dangers caused by mankind, it is undeniably perplexing to know the upsurge in population that leads to the dearth and privation of resources. Under supplied resources intensify the need in man and incite him to discover alternatives to sustain his livelihood. Sustainability aims to bring steadiness in both anthropoids and nature. Barry Commoner in Closing Circle states the interdependency of lives with the ecosystem. All the networks in the web of life are vital, when one of the connections is disturbed the entire web of life is prone to threat leading to catastrophe which leads to annihilation and death. Harmony could be anticipated when both coexist together and are limited in their terrains without bewildering the existence of the other. Unfortunately, that is not the possibility in today’s world, the whole ecosystem is becoming unusual by the deeds of men who strive to support their survival. Human’s interventions have altered the whole functionality of nature and have created a faux inhabitation, forcing humans to believe that the sceptre has passed from nature to mechanization.A fragile environment is prone to dangers caused by mankind, it is undeniably perplexing to know the upsurge in population that leads to the dearth and privation of resources.
