قرآن کی سائنسی تفسیر اور دعوت الی اللہ: ’’کتاب زندگی‘‘ کا تجزیاتی مطالعہ
Authors: Iffat Batool
Published: March 2023

The scientific revolution has left the world in awe and laid the foundation for scientific evidence-based research. It has also provided the premise for religious scholars to incorporate scientific precepts into their learning and interpretation of the Quran. This idea was proposed by early Muslim Scholars like Ghazali and Razi. However, this field has become increasingly important in the contemporary era as Muslim researchers seek to inspire western scholars and attract their attention to the miraculous nature of the Quran. In this context, this article provides a critical analysis of Sultan Bashir's Quran's scientific interpretation of Surah Fatihah and Baqarah to highlight his efforts in this regard and to guide future research in this area of study.

Published: March 2023

We establish the existence of weak solution for a class of $p(x)$-Kirchhoff type problem for the $p(x)$-Laplacian-like operators with Dirichlet boundary condition and with gradient dependence (convection) in the reaction term. Our result is obtained using the topological degree for a class of demicontinuous operators of generalized $(S_{+})$ type and the theory of the variable exponent Sobolev spaces. Our results extend and generalize several corresponding results from the existing literature.

Published: March 2023

يتناول هذا البحث ظاهرة لغوية مستعملة بكثرة في القرآن الكريم والحديث الشريف وكلام العرب وفي كلامنا الحالي وهي ظاهرة القطع في الإضافة في نوع معين من الألفاظ التي تقطع عن الإضافة والتي اصطلح النحاة على تسميتها بالغايات، وآراء اللغويين والبلاغيين والمفسرين وخلافاتهم فيها نحويا ودلاليا وبخاصة في القرآن الكريم، ومدى اتفاق آرائهم وتعليلاتهم النحوية أو اختلافها باعتبار هذا الموضوع من أكثر الموضوعات اللغوية جدلا وتعليلا، ومدى مراعاة الجانب الدلالي لهذه الظاهرة، ومدى وجود هذه الظاهرة في القرآن الكريم وقراءاته. وقد تناول البحث جانبين أساسيين لظاهرة القطع في الغايات وهما الجانب النحوي والدلالي، ومن الصعب فصل أحدهما عن الآخر في مبحثين منفصلين؛ لتداخلهما وتكامل الحديث عنهما. وخرج البحث بجملة من النتائج من أهمها أن لظاهرة القطع في الغايات أغراضا دلالية متنوعة يحددها السياق، وأن هذه الظاهرة من الظواهر التي ما زالت حية مستخدمة في أساليبنا وتراكيبنا؛ لما لها من دور في إعطاء المجال للمتكلم والمخاطب لتنويع الدلالات وإثراء المعاني مقارنة بظاهرة القطع في النعت -مثلا- التي أصبحت منقرضة أو نادرة الاستعمال في كلامنا، وقد اعتمد البحث على المنهج الوصفي نظرا لطبيعته القائمة على الوصف والتحليل.
Antimicrobial, Antibiofilm and Antiurease Activities of Microbially Synthesized Silver Nanoparticles against Proteus mirabilis
Authors: GÜRKÖK Sümeyra , ÖZDAL Murat
Published: March 2023

Nanoparticles (NPs) are tiny materials ranging in size from 1 to 100 nm and have unique magnetic, electrical, and optical characteristics differing from bulk materials. They have a broad spectrum of applications in different industries. Several physical and chemical techniques have been applied to produce metal NPs. Alternatively, green synthesis offers an environmentally friendly and simple means for NP preparation. In the present study, silver NPs were produced by the Pseudomonas aeruginosa OG1 strain. Characterization of NPs was performed by TEM, SEM, and XRD. These NPs were used against pathogenic Proteus mirabilis, which shows high-level urease activity and forms clear biofilms. Silver NPs obtained in the present study were applied to inhibit the growth, urease production, and biofilm formation of P. mirabilis. Growth inhibition zones of 9 mm and 11 mm and, 60 % and 85% antibiofilm effects were obtained by 100 µg mL-1 and 200 µg mL-1 NPs, respectively. The urease activity of P. mirabilis was completely inhibited in both concentrations. These results show that AgNPs can be used as effective antimicrobial, antibiofilm, and antiurease agents in the fight against pathogens.
L’INCIDENCE DES MALADIES ET DES RAVAGEURS SUR LA CULTURE DU CACAO (THEOBROMA CACAO) A KINDU, R.D.CONGO.
Authors: Bernard Ir. SHABANI KASONGO
Published: March 2023

En République Démocratique du Congo en générale et dans la province du Maniema en particulier, la culture du Cacao « Theobroma cacao » est essentiellement pratiquée par des paysans qui utilisent des méthodes traditionnelles ou empiriques. Cette étude signale que les maladies pouvant attaquer la culture du Cacao existe bien  à Kindu et ses environs et que les symptômes sont indicateurs d’une baisse de production, comme cela prouvé ailleurs. Cet état des connaissances pourrait être guidé par des tests d’expérimentations et d’analyses poussées pour mieux comprendre l’expansion du phénomène dans la province du Maniema en générale et dans la ville de Kindu particulier. Des paramètres liés à la maladie (l’incidence, le taux d’attaques foliaires, l’indice de gravité des symptômes et la chute précoce des cabosses, la perte de rendement) ont été étudiés.

Les résultats obtenus ont montré que les Cacao de Kindu sont infectés avec une incidence variant entre (16,82%) et (54,22%) à Kindu et un taux d’attaque moyen variant entre 11% et 29%. Nous avons constaté d’après ces résultats, que 54,22% des plants infectés affichent des indices de sévérités ou Indice de Gravité des Symptômes IGS inquiétants qui varient de 1 à 4 susceptibles de faire baisser la production dans le zone étudiée. L’impact économique de maladies et ravageurs de la culture de Cacao s’est traduit par une perte de rendement  au niveau des cabosses réduisant de façon significative les efforts des paysans cultivateurs. Il serait nécessaire de réglementer le contrôle et la distribution des semences  saines et/ou matériels de culture sains, la sélection des variétés, l’éducation des paysans pour l’amélioration des techniques culturales et la maitrise des différents paramètres agronomiques.
EXAMINING THE EFFECT OF CLIMATE CHANGE ON THE SUSCEPTIBILITY OF ROAD PAVEMENTS IN SOUTH-SOUTH NIGERIA USING THE DELPHI METHOD
Authors: E. Isemede Eric
Published: March 2023

Asphalt pavements constitute a high portion of Nigeria's roadways, which have high traffic volumes. The potential deterioration in the long-term performance of these pavements due to climate change has not been given much research attention. To this extent, the present study evaluated the pavement susceptibility of Federal roads in Edo state of South-South Nigeria. The study employed the Delphi technique to examine expert opinions. The standard deviation of the answers to two rounds of questionnaires was used to evaluate the consensus reached by the 10-person Delphi panel. The result showed that one of the four federal roads analyzed in the study was classified as having a high susceptibility, two were classified as having a medium susceptibility, and the remaining road was classified as having a low susceptibility. This research demonstrates that the Delphi technique, which incorporates both objective and subjective assessments, can comprehensively evaluate road pavements' vulnerability to climate change. Therefore, the government should employ adaptive maintenance plans for the roads' varying degrees of susceptibility.

Authors: Yaruingam Prof. A. S. , Gupta Ms. Jyoti
Published: March 2023

A long and healthy life, access to knowledge, and a reasonable standard of living are the three fundamental dimensions of human development that the HDI measures in summary form over time. The life expectancy at birth is used to evaluate the health dimension, and the mean number of years spent in school for adults 25 years and older and the anticipated number of years spent in school for young children are used to evaluate the education dimension. Gross national income per person is used to measure the standard of living dimension. The HDI uses the logarithm of income to reflect how income becomes less significant as GNI rises. The three HDI dimension indices' scores are then combined using geometric mean to create a composite index.

Value Alignment for Advanced Artificial Judicial Intelligence
Authors: Winter Christoph , Hollman Nicholas , Manheim David
Published: March 2023

This paper considers challenges resulting from the use of advanced artificial judicial intelligence (AAJI). We argue that these challenges should be considered through the lens of value alignment. Instead of discussing why specific goals and values, such as fairness and nondiscrimination, ought to be implemented, we consider the question of how AAJI can be aligned with goals and values more generally, in order to be reliably integrated into legal and judicial systems. This value alignment framing draws on AI safety and alignment literature to introduce two otherwise neglected considerations for AAJI safety: specification and assurance. We outline diverse research directions and suggest the adoption of assurance and specification mechanisms as the use of AI in the judiciary progresses. While we focus on specification and assurance to illustrate the value of the AI safety and alignment literature, we encourage researchers in law and philosophy to consider what other lessons may be drawn.
The Impact of Developing Fintech on Banks
Authors: Yang Yuanjin , Zhang Xun , Feng Bao
Published: March 2023

In recent years, the rapid development of financial technology (fintech) has greatly impacted the traditional banking industry, posing both challenges and opportunities for banks. In this study, we investigate the influence of fintech on the net interest margin and non-performing loan ratio of banks in China.To measure the level of fintech development in banks, we construct a Bank Fintech Development Index (BFDI) based on text analysis of annual reports. We then use a panel data regression model to analyze the impact of fintech development on the net interest margin and non-performing loan ratio of banks, controlling for other factors such as bank size, capital adequacy, and macroeconomic conditions.Our empirical results show that the development of fintech has a significant positive impact on the net interest margin of banks, indicating that banks that have adopted fintech are able to generate higher profits from their interest-bearing assets. We also find that the development of fintech has a significant negative impact on the non-performing loan ratio of banks, suggesting that fintech can help banks improve their risk management and reduce their credit losses.Therefore, banks should continue to embrace fintech and invest in new technologies to remain competitive in the rapidly evolving financial landscape.
Molecular extension engineering constructing long-chain organic elastomeric interphase towards stable potassium storage
Authors: Zhou Jiang , Lu Bingan
Published: March 2023

Electrolytes are critical for achieving high performance potassium ion batteries (PIBs) because of their ability to modulate the solid electrolyte interphase (SEI). However, the compositions of SEI in conventional electrolytes are either anion-derived inorganic-rich compounds or solvent molecule-derived short-chain organic-rich compounds. These SEI are generally inelastic and cannot effectively relieve the stress changes caused by volume changes during the charge/discharge processes. Here, we constructed long-chain organic-rich SEI (LO-SEI) with high elasticity by introducing a green and harmless long-chain solvent of dicaprylyl carbonate (DCC), thus greatly improving the performance of PIBs. As a result, a long stability of more than 1500 cycles (86.7% capacity retention) for graphite half-cells and more than 3700 hours for K||K symmetric cells are achieved. In addition, the elastomeric LO-SEI-based full cell is capable of stable operating for more than 130 cycles (84.3% capacity retention). This work may open new ideas for constructing long-chain elastic interphases to achieve high-performance batteries.

Authors: Wang Yu , Alvarado Irma
Published: March 2023

Background: Sepsis is a common and costly medical emergency, often leading to unplanned readmissions. The purpose of this quality improvement project is to integrate staff education, every 4 hours vital signs monitoring guided by sepsis screening score, and structured response via a process map to reduce unplanned 30-day readmission rate by 25% from baseline at a hospital-based skilled nursing facility (HBSNF).Methods: This project was conducted at an 18-bed HBSNF. Prior to implementing this project, all registered nurses and patient care assistants received education on sepsis. Registered nurses were also trained in the proper use of Nursing Sepsis Management Order Set and How to Respond: A Patient with Suspected Sepsis Process Map. From September 1 to November 30, 2020, the project gradually increased vital signs monitoring frequency from every 12 hours to every 4 hours based on patients’ sepsis risk stratified by sepsis screening score in 3 phases. Systemic Inflammatory Response Syndrome criteria was used to identify sepsis-related unplanned readmissions.Results: Overall, the 3-month vital signs monitoring compliance rate was 96% (5019/5223). The sepsis-related unplanned 30-day readmission rate was reduced from baseline 47% (17/36) to 21% (4/19) at the end of this project, about a 55% decrease from baseline.Conclusions: The combination of an evidence-based electronic surveillance system and change in management strategies significantly reduced sepsis-related unplanned 30-day readmissions at this HBSNF. Dissemination of these innovations could improve sepsis management in other HBSNFs and positively impact patients’ health outcomes and healthcare costs.

Published: March 2023

Rhabdomyosarcoma is a soft tissue highly malignant neoplasm. The most common sites in childhood are the head and neck with only 10% of all cases occurring in the orbit. Clinical manifestations are not specific which makes pre-operative diagnosis challenging. Orbital tumors are mostly detected at early stages, due to their obvious symptoms but they are characterized with a rapid growth. Imaging techniques and especially MRI are very contributive in the diagnosis process. The purpose of this review is to provide a general overview of primary orbital Rhabdomyosarcoma through a representative case of a patient that has been managed at our institute as well as a review of the literature.

Analysts’ Attention and R&D Expenditure: The Mediating Role of Financial Constraints
Authors: Wang Qingmiao
Published: March 2023

Analyst plays an important role in the development of an enterprise. Meanwhile, during the process of this development, it is important to gain financial support. Analysts' opinions can change public investors’ behavior and sentiments dramatically. However, the relationship between the three factors is still waiting to be discussed. This article focuses on the relationship between analysts’ attention, corporate finance, and corporate innovation, using OLS and Panel FE estimation methods to analyze the problem, and finally concludes that analysts’ attention can reduce financial constraints and then have a positive influence on corporate innovation. Moreover, compared with a large company, middle and small-sized enterprises are influenced more by this attention. Based on the research result, this article proposed that companies, especially the middle and/ or small-sized companies, should pay attention to making the third party (i.e., the analysts) interested in them and increase their exposure among the analysts and the public.
The Dynamic Impact of Covid-19 Pandemic on Environment-friendly Energy Industry
Authors: Zhou Wen
Published: March 2023

Most of the current research on green energy and the pandemic focuses on how green investments changed after the epidemic and how the pandemic affected the local economy. The correlation between the rate of return on green energy and the number of confirmed cases in China and the rest of the globe is the main topic of this research. The daily cumulative confirmed Covid-19 cases in China and the rest of the world, and daily price of green energy are used as time series variables. They are daily data from the end of January 2020 to the end of July 2022. The study's findings largely show how the price of green energy has changed in relation to the pandemic's progression. A VAR (12) model makes a forecast on how the pandemic, which is expected to become stationary after the tenth period, would affect the price of green energy. The ARMA-GARCH model's findings demonstrate a statistically significant negative correlation between the price of green energy and the number of verified cases. In other words, compared to the pandemic, the price of green energy is lower. The pandemic has had no impact on the rate of return of green energy throughout the specified period, though.
The Effects of Bitcoin Futures on Bitcoin Market
Authors: Hong Yu
Published: March 2023

In the five years after the launch of bitcoin futures, academics and investors' perceptions have shifted from the early view that they raise the risk of bitcoin to the present acceptance of their ability to serve as derivatives. This change indicates that bitcoin futures have the potential to improve. What influences the bitcoin market has received from bitcoin futures is investigated in this paper. The introduction of bitcoin futures has offered a feasible hedging strategy for bitcoin investors, enhanced the stability and information effectiveness of the bitcoin market, also eased the investment barrier for bitcoin, based on study and comparison of previous research on bitcoin futures. However, because bitcoin futures are the novel type of futures contract, the market is complicated, and investors prefer to trade unregulated futures, whereas regulated futures are traded in considerably lesser quantities due to position limitations. Exchanges that regulate bitcoin futures should consider changing their contract positions to allow more investors to engage in trading while obtaining regulatory protections in to enable the bitcoin futures market to develop more maturely in the future.
Endowment Effect: Experimental Tests and Literature Study
Authors: Wong Siu Yu Sheila
Published: March 2023

In everyday economic life, the endowment effect is a very frequent occurrence. It describes the phenomena wherein a person values a possession more highly when they own it than when they do not. At present, the psychological mechanism of this phenomenon is mainly explained by loss aversion, but this theory has great defects. A theoretical area of behavioral finance is endowment effect. In order to analyze the psychological traits of financial market subjects (decision-makers) in financial market behavior and to study investor decision-making behavior and its effects on asset pricing, the field of behavioral finance is founded on theories of behavior, finance, sociology, economics, decision-making, and psychology. It questions conventional economics. The endowment effect contradicts the rational person hypothesis of conventional economics and accurately represents the research techniques of behavioral finance. Future research can combine psychology and economics to further explore the psychological mechanism of this phenomenon. Combined with the influence of endowment on Coase theorem, explore the practical significance of endowment effect.

Investors often use gold and Bitcoin to reduce the risk of financial investments by combining them due to their low correlation and different dynamic correlation. Therefore, it is essential to study how a combination of the two can be invested to maximize returns. In this paper, we combine the BP neural network model and the gray correlation analysis model from the future unpredictability and risk quantification of portfolio investment. We want to use the model to construct a price prediction model and risk assessment model to build a model for portfolio investment decisions based on past-day price flow only. To be specific, this paper first builds a price prediction model based on a BP neural network prediction model. At the same time, the prediction needs to be performed in a cycle, and the training set of the neural training model is increased each time. Each prediction is recorded for the next day's data and aggregated to obtain the daily price flow prediction. Next, this paper builds a risk assessment model through gray correlation analysis. In order to measure the riskiness of the daily investment, this paper selects three indicators, namely, forecast price accuracy, recent price trend, and price volatility. It uses gray correlation analysis to score them quantitatively and then gives the daily investment risk assessment results. Finally, a sensitivity analysis was performed to determine the model's sensitivity to transaction costs by varying the transaction costs of gold and bitcoin. It was found that as the transaction costs become more extensive, the number of transactions becomes smaller and the total assets acquired become smaller.
Research on the Problems Related to the Life Work Balance and Psychological Health Problem of Chinese Millennial Workers as an Economic View
Authors: Zhang Yukun
Published: March 2023

The majority of workers, the millennial generation, are more likely than workers from other generations to have subjective opinions on their employers, according to the survey. When it comes to employment, Millennial workers prefer the odd job market, where the boss' demands are not imposed, and the ability to switch jobs frequently. They just see employment as a way to make money. As a result, the outdated labour system does not satisfy the requirements of Chinese millennial workers. The three research approaches used in the work are positivism, empiricism, and interpretivism. This essay uses the empirical analysis method of positivism to interview employees of a Shanghai consulting firm about their experiences with work-life balance while performing actual job responsibilities. Their replies to the research suggest that the only way for corporate leaders to better problem-solving is for them to understand their challenges. The findings of this study indicate that there is still much to be discovered regarding millennial "work attitudes" and work-life balance in China. Thus, there are numerous complex topics that call for additional discussion.
