Authors: Garba Abubakar , Mahmoud Mahmoud Ahmad , Sabo Fatima Usman
Published: August 2024

The aim of the study is to examine women entrepreneurs’ motivation to participate in agribusiness value chain. Specifically, the study assessed the role of demographic factors, institutional factors and socio-cultural factors on women motivation towards entrepreneurship participation based on either opportunity or necessity. The study used cross-sectional survey design in which data was collected from 219 women entrepreneurs in Kano State's agribusiness value chain. It employed binary logistic regression, a statistical method that involved observing and analyzing multiple statistical outcome variables simultaneously. This approach is particularly useful in situations where multiple measurements were made on each experimental unit. The study found that demographic, institutional and socio-cultural factors influenced women entrepreneurial motivation to agribusiness. The result indicates that educational level and age are significant demographic factors that influence women participation in agribusiness. It discovered that the probability of women to be motivated in participating in agribusiness to pursue an opportunity is decreasing with more education attainments, while, the probability of women to be motivated to participate in agribusiness is increasing with their ages. The study reveals that the probability of women to be motivated to participate in agribusiness based on opportunity is decreasing with access credit facility (IFACF), access to market (IFAM) and access to government grant and support (IFAGS). While, the probability for women to be motivated to participate based on opportunity is increasing with accessing training and other extension services (IFATES). It further indicates that the possibility for women to be motivated to participate based on necessity is increasing with socio-cultural influences, while decreasing for opportunity-pull entrepreneurs. The study highlights to policy makers that opportunity-pull entrepreneurs may not be affected by socio-cultural factors as it will do to necessity-push entrepreneurs. It has shown that the necessity entrepreneurs have limitation to exploit opportunities due to their poor background, low social networks and are only struggling to survive.  This study is constrained to collect data from only women in urban areas as such the research findings is cannot be applied to those in the rural areas. The study contribute in enriching the literature by providing explanation on the role of demographic, socio-cultural and institutional factors on women who participate in agribusiness based on either necessity or opportunity.

Authors:   Assistant Professor of the Department of civil procedure of the Ural State Law, Tarasov Igor’ N
Published: August 2024

In the article, the author examines some problems of the implementation of the procedural right to claim evidence outside the Russian jurisdiction. The author discusses the criteria by which the court, using its powers, can come to a reasonable conclusion about the need to claim evidence outside Russia. The author discusses the models of suing, which are the most common in world practices — notice pleading and fact pleading. Such a construction from the common law system as the Norwich Pharmacal Order (NPO) is given as an example for analysis. The author also discusses ways to obtain evidence from foreign jurisdictions — the use of legal assistance mechanisms provided for by international agreements or the demand for evidence from a foreign participant directly, that is, without an official request to the court of the state where the relevant evidence or information is located. The aspects of using these approaches and the problems arising from these approaches are studied. For example, the problem of verifying the evidence obtained, the problem of abuse, etc.

THE ESSENCE OF THE ISLAMIC FAMILY
Authors: Komarudin Koko
Published: August 2024

The discussion of the Islamic family means discussing the families that are scattered all over the world where Islam is part of the religion followed by the population. Islamic family law (al Akhwal al Syakhsiyyah) is the main part of Islamic law with a larger portion and high enough attention, both from the heavens, namely divine revelation (Al-Qu'ran) and the Sunnah of the Prophet Muhammad as well as from the applicable laws and regulations in each country. . Islamic family law is basically here to provide a comprehensive and integral understanding and insight into how to have a family in accordance with Islamic rules. The aim is to provide assistance so that they can subside or prevent sources of disputes among family members and even offer ways to solve all the problems that occur and are faced by every Muslim family. The essence of the Islamic family is an ideal of the embodiment of the family which bases all activities and communication and interactions both in peaceful conditions and in an atmosphere of dispute on Islamic rules derived from the Al Quran and hadith. With regard to an Islamic family in a country, he cannot escape from binding rules such as the Marriage Law and the Compilation of Islamic Laws. This is in order to realize the noble ideals of the Islamic family, namely to build a sakinah family, mawaddah warahmah. The Islamic family does not mean that it does not face challenges and strife. However, the Islamic family always tries to resolve every case, problem, and conflict that occurs between family members by referring back to the Al-Qur'an and hadith and if necessary, the parties concerned such as the Office of Religious Affairs (KUA) and the Religious Court (PA) be involved in solving the problem. The final hope is that all activities that occur in the Islamic family can represent all maqashid al-syari'ah, namely hifdz al inen, hifdz al nafs, hifdz al aql, hifdz al nasl and hifdz al maal.

Deep Unfolded Tikhonov Regularized Conjugate Gradient Algorithm for MIMO Detection
Authors: Karahan Sümeye Nur , Kalaycıoğlu Aykut
Published: August 2024

In addressing the multifaceted problem of multiple-input multiple-output (MIMO) detection in wireless communication systems, this work highlights the pressing need for enhanced detection reliability under variable channel conditions and MIMO antenna configurations. We propose a novel method that sets a new standard for deep unfolding approaches to MIMO detection by integrating the iterative conjugate gradient method with Tikhonov regularization, combining the adaptability of modern deep learning techniques with the robustness of classical regularization. Unlike conventional techniques, our strategy treats the regularization parameter of Tikhonov regularization as well as step size values and search direction coefficients of conjugate gradient (CG) method as trainable parameters within the deep learning framework, allowing for dynamic modification according to channel conditions and MIMO antenna configurations. Detection performance is significantly improved by the proposed approach in variety of conditions. In different MIMO settings, the suggested method consistently shows better bit error rate (BER) and normalized minimum mean square error (NMSE) performance. Across a range of MIMO configurations and channel conditions, the proposed method exhibits significantly lower BER and NMSE values than well-known techniques such as DetNet and CG. The proposed method has superior performance over CG and other model-oriented methods, especially in small number of iterations. Consequently, the simulation results demonstrate the flexibility of the proposed approach, making it a viable choice for MIMO systems with a range of antenna configurations and different channnel conditions.
Mathematical Models of Tsunami Propagation

Published: August 2024

Tsunami is a type of infrequent geohazards with devastating consequences, which makes accurate computer simulations of tsunami waves particularly desirable for hazard assessment and mitigation purposes. The evolution of a typical tsunami involves the generation, propagation and inundation phases. In this survey, we briefly describe the most common types of tsunamigenic sources and give a detailed review of some most widely used mathematical models for describing tsunami propagation. We emphasize the approximations adopted in each mathematical model and point out their most important advantages and disadvantages. Tsunami propagation modeling is computationally demanding, involving a wide span of spatial and temporal scales. While some of the approximate models are sufficiently accurate for describing wave behaviors at certain scales, they might not be applicable at other scales. Effective and efficient tsunami propagation simulations will likely depend upon the proper coupling of different models for different scales.

Antimicrobial Peptides Derived from Bacteria: Classification, Sources, and Mechanism of Action against Multidrug-Resistant Bacteria
Authors: Mihaylova-Garnizova Raynichka , Davidova Slavena , Hodzhev Yordan , Satchanska Galina
Published: August 2024

Antimicrobial peptides (AMPs) are short, usually cationic peptides with an amphiphilic structure, which allows them to easily bind and interact with the cellular membranes of viruses, bacteria, fungi, and other pathogens. Bacterial AMPs, or bacteriocins, can be produced from Gram-negative and Gram-positive bacteria via ribosomal synthesis to eliminate competing organisms. Bacterial AMPs are vital in addressing the increasing antibiotic resistance of various pathogens, potentially serving as an alternative to ineffective antibiotics. Bacteriocins have a narrow spectrum of action, making them highly specific antibacterial compounds that target particular bacterial pathogens. This review covers the two main groups of bacteriocins produced by Gram-negative and Gram-positive bacteria, their modes of action, classification, sources of positive effects they can play on the human body, and their limitations and future perspectives as an alternative to antibiotics.
Lipase B Immobilized Silica-coated Magnetic Nanoparticles for Rapid Hydrolysis, Acylation, and Lipolysis
Authors: Kim Yu Jeong , CHANG JEONG HO
Published: August 2024

This study reports rapid hydrolysis, acylation, and lipolysis with lipase B from Candida antarctica (CalB) and nanofructosome encapsulated CalB (CalB@NF) enzymes immobilized on silica-coated magnetic nanoparticles (Si-MNPs). Enzymatic hydrolysis was confirmed for conversion to p-nitrophenol (p-NP, λex=400 nm) from p-nitrophenyl butyrate (p-NPB, λex=270 nm), and various catalytic parameters such as Km, Vmax, and Kcat were calculated from Michaelis-Menten and Lineweaver-Burk plot. Efficiency of enzymatic hydrolysis was in the order of CalB > Si-MNPs@CalB > CalB@NF > Si-MNPs@CalB@NF, and reusability was much better with the enzyme immobilized on Si-MNPs than with the native enzyme. Enzymatic acylation was confirmed by the formation of benzyl benzoate (λex=229 nm) from benzoic anhydride (λex=240 nm), and efficiency exceeded 99% in all samples. Finally, enzymatic lipolysis was confirmed by the decomposition of olive oil to fatty acid such as oleic acid (λex=230 nm) using thin-layer chromatography (TLC), column chromatography, and proton nuclear magnetic resonance (1H -NMR). The lipases immobilized on Si-MNPs have the advantage of good thermal stability and reusability and are thus applicable to a wide range of industries.

The Need of Chloride-37 Enrichment for Molten Salt Fast Reactors
Authors: Degueldre Claude , Merk Bruno
Published: August 2024

The use of natural chloride in the salt fuel has been sometimes promoted for the chlorine based molten salt fast reactor using for example NaCl-UCl4- UCl3. Most of the chemistry based R&D has been carried out on natural chloride, while in reactor physics most of the calculations are based on enriched chloride-37. In any case, the use of natural chloride (75.77% 35Cl and 24.23% 37Cl) induces specific ecological and neutron economical issues. An ecological issue is the production of 36Cl by neutron activation of 35Cl. Chlorine-36 is a soluble long live nuclide that makes it a ‘first’ nuclide in the safety assessment of the repository. We explore the build-up of 36Cl with burnup for various 37Cl (activation product) enrichment. The neutron economical aspect is gained by achieving reactor criticality with a lower amount of fissile material achieved through the use of enriched chloride-37. The criticality (k) of a core is much larger for enriched chloride than for the natural one. The reactor with 99% 37Cl would have a k99/knat of 1.04346 which would allow to reduce the required uranium enrichment and thus the fuel cost. This reactivity gain is evaluated for various 37Cl enrichment factors to estimate uranium enrichment gain achievable through 37Cl enrichment. However, from economical point of view it could be of interest to use as some kind of compromise solution natural NaCl, which will be analysed, too. Production/enrichment of 37Cl can be performed by physical separation e.g. gas centrifugation of 1H35/37Cl or by chemical separation using anion partitioning and elution of 23Na35/37Cl on solid adsorbent columns or in liquid – liquid extraction systems. These techniques require however extensive investigations including chemical thermodynamics and hydrodynamics. Comparisons are suggested on the basis of the separation factor α. Recommendations are finally given for utilising 37Cl in the fast molten salt reactor. The enrichment work for 37Cl is smaller than the work needed for 235U enrichment.

We recently demonstrated the effectiveness of long-term treatment with rifaximin and the probiotic VSL#3 at improving urogenital and gastrointestinal symptoms in patients with both chronic inflammatory prostatitis (IIIa prostatitis) and diarrhea-predominant irritable bowel syndrome (IBS-D), relative to patients with IBS-D alone. Because low-grade inflammation of the intestine and prostate may be one of the reasons for co-developing both IIIa prostatitis and IBS-D, we designed the present study to once again evaluate the efficacy of combined rifaximin and VSL#3 treatment in patients affected by IIIa prostatitis plus IBS-D, but we also measured seminal plasma pro-inflammatory (IL-6) and anti-inflammatory (IL-10) cytokines before and after treatment. We consecutively enrolled 124 patients with IIIa prostatitis and IBS-D (diagnosed using the Rome III criteria). Patients were randomized into two groups: group A (n=64) was treated with rifaximin (seven days per month for three months) followed by VSL#3, and group B (n=60) was treated with a placebo. At the beginning of the study and after three months of treatment, all patients completed NIH-CPSI and IBS-SSS questionnaires to score the severity of their urogenital and gastrointestinal symptoms, and we measured seminal plasma levels of IL-6 and IL-10 using ELISA. We defined patients who improved following the treatment as those with a ≥6-point reduction in their NIH-CPSI score or ≥50-point reduction in their IBS-SSS score. By the end of the intervention, 68.7% and 62.5% of patients from group A reported improved NIH-CPSI and IBS-SSS scores, respectively, compared to only 3.3% and 5% of the placebo group. Group A patients also had significantly lower mean seminal plasma levels of IL-6 (11.3 vs 32.4 pg/mL) and significantly higher mean levels of IL-10 (7.9 vs 4.4 pg/mL) relative to baseline, whereas levels of IL-6 and Il-10 did not change in the placebo group. The co-occurrence of two clinical phenotypes (IBS-D plus IIIa prostatitis) result in increased intestinal inflammation and altered immune activation, both of which can be balanced by treatment with rifaximin and VSL#3.

Iron (Fe) is co-factor for enzymes of the developing brain necessitating sufficient supply. We investigated the effects of administering ferric derisomaltose/Fe isomaltoside (FDI) subcutaneously to Fe deficient (ID) pregnant rats on cerebral and hepatic concentrations of essential metals and gene expression of ferroportin and hepcidin. Pregnant rats subjected to ID were injected with FDI on the day of mating (E0), 14 days into pregnancy (E14), or the day of birth (Postnatal (P0)). The efficacy was evaluated by determination of cerebral and hepatic Fe in pups on P0 and as adults on P70, and the concentration of copper (Cu) and zinc (Zn). Females fed an ID diet (5.2 mg/kg Fe) had offspring with significantly lower cerebral and hepatic Fe compared to female controls fed a standard diet (158 mg/kg Fe). Cerebral Cu increased irrespective of supplying a standard diet or administering FDI combined with the standard diet. Hepatic hepcidin was significantly lower following ID, whereas cerebral hepcidin was virtually undetectable in all experimental groups. In conclusion, administering FDI subcutaneously to ID pregnant rats on EO normalizes cerebral Fe in the fetus, but when applied at later gestational ages, additional Fe to the offspring is needed to normalize cerebral and hepatic Fe.
Enhancing Indoor Thermal Comfort with Vertical Greenery: A Simulation Study on Heavyweight Walls in Mediterranean Climates

This study investigates the impact of vertical greenery systems (VGS) applied to heavyweight walls on indoor thermal conditions in a building module situated in the Mediterranean climate of Catania, Italy. Using dynamic simulations in TRNSYS, the research compares the thermal behavior of walls constructed from hollow clay blocks (Poroton) and lava stone blocks with a lightweight wall setup already in place at the University of Catania. The primary focus is on evaluating the VGS’s effect on reducing peak inner surface temperatures and moderating heat flux fluctuations entering the building. The findings indicate that adding a vertical greenery layer to heavyweight walls can decrease the peak inner surface temperature by up to 1.0°C compared to the same wall without vegetation. However, the greenery’s impact on mitigating heat flux fluctuations is less pronounced than in the case of the lightweight wall. This research underscores the potential of green facades in enhancing indoor thermal comfort in regions with climates similar to the Mediterranean, providing valuable insights for sustainable building design and urban planning.

Objective: Breast cancer (BC) is the most common cause of death among females. There are many prognostic systems, the most recent of which are the molecular subtypes. Recently, it was included that thyroid disease is a favorable factor for the patients with BC and that the thyroid hormones have an effect on the disease. Thyroid stimulating hormone (TSH), however, is thought to be unrelated to the cancer aggressiveness. In the current study we aimed to examine the status of the postoperative TSH levels, as well as the impact of the thyroid disease on the cancer aggressiveness.
Methods: A retrospective comparative analysis of invasive BC patients was performed between 2017 and 2019 year. 111 patients were selected. They were divided into group A (n=62) and group B (n=49), based on the presence or absence of thyroid disease, respectively. The data was processed with SPSS version 25.
Results: There is a significant difference between group A and group B concerning the molecular subtypes, ki-67, and estrogen receptor. The current study supports the fact that TSH is responsible for the aggressiveness of the invasive BC and not the thyroid hormones themselves. Moreover, based on the correlation analyses calcium levels preoperatively are linked to cancer aggressiveness and could be used as future prognostic factors.
Conclusion: Indeed, the thyroid disease appears to have more favorable prognosis based on the molecular subtype frequency but more emphasis in future studies should be given to the TSH and its relation to the overall survival of the patients.
