Authors:   , Phimmakone Yot
Published: November 2023

The purpose of this study is to verify dosimetric accuracy of 6 MV X-ray beams for Acuros XB algorithm in Eclipse TPS by comparing measurements and calculations of beam characteristics and clinical applications. The beam characteristics were studied in various square and rectangular fields for PDDs, profiles and output factors by measurement in water phantom. The PDDs were measured by scanning with CC13 ion chamber, while in-plane and cross-plane profiles were acquired with PFD diode at 5, 10 and 20 cm depths. The output factors were measured at 10 cm depth using CC13 ion chamber. In clinical applications, the selected 15 cases in head, chest and pelvic regions of 3D-CRT, IMRT and VMAT techniques in homogeneous and heterogeneous medium were measured with CC13 ion chamber and compared with calculated dose in Eclipse TPS. The results of measured PDDs showed a good agreement to TPS with the average of δ1 (high dose, small dose gradient) at 0.16±0.64% and δ2 (high dose, large dose gradient) at 0.43±0.70 mm. Both measured in-plane and cross-plan profiles in all field sizes and all depths displayed the coincidence results with calculated profiles that showed δ2 less than 2 mm, δ3 (high dose, small dose gradient) within 3%, δ4 (low dose, small dose gradient) within 3%, and δ50-90 within 2 mm. The maximum output factors differences were -1.54%. For clinical application, the dose verification in homogeneous showed the maximum dose differences of 0.71% for 3D-CRT, -2.95% for IMRT and 2.70% for VMAT plans. While, inhomogeneous showed of the maximum dose error of 3D-CRT, IMRT, and VMAT plans at 0.61%, -2.27%, and -1.9% for 3D-CRT, IMRT, and VMAT plans, respectively. These dose differences were within the tolerance of ±3% for homogeneous and ±5% for heterogeneous medium as the recommendation from AAPM TG-53 and IAEA TRS 430. Therefore, the Acuros XB algorithm can be implemented in Eclipse TPS of clinical application radiotherapy.
Effects of iron and inflammation on astrocytes functions
Authors:   , Chaiyana Woranittha
Published: November 2023

Iron accumulation and inflammation are present in a variety of neurodegenerative diseases include Alzheimer's disease and Parkinson's disease. Nowadays it has not yet known what the specifically causes neurodegeneration. There is probably not one single, but several factor are important to describe the etiology of these diseases. In this study, ferric ammonium citrate, pro-inflammatory cytokines including interleukin 1β and tumor necrosis factor alpha and combined were investigated the altered astrocytes functions. The results showed that FAC and combination of cytokines were markedly induced intracellular iron accumulation, free iron and reactive oxygen species, while the proliferation was inhibited in the presence of combination. In addition, the results demonstrated that iron enriched astrocytes alters the genes expression profiles involved in iron homeostasis by increased the expression of iron importer and storage genes couple with decreased in iron exporter gene. According to this condition, the rearrangement of astrocytes cytoskeletons were observed in an alteration of intermediate filaments, GFAP and vimentin, which refer to an initially activated astrocytes. Moreover, the combination of FAC and cytokines was able to induce the expression of the inflammation response genes including IL-1β, IL-6 and TNF-a. At the same time, the presence of FAC and combination of cytokines were significantly increased cytokines levels including IL-1β, IL-6 and TNF-a and glutamate secretion compared to unexposed control cells. Taken together, these findings suggest that astrocytes in neurodegenerative disorders are oxidatively stressed due to their tendency to accumulate iron, express and release more of cytokines and glutamate that can be harmful to neuron.
HEV Seroprevalence, Serum and Feces HEV RNA positivity in Post-Liver Transplant Patients During 1-year Follow-up Period
Authors:   , Oranrap Vinita
Published: November 2023

Introduction: Hepatitis E virus (HEV) has emerged as an important infectious disease in immunocompromised patients, especially those who are post-liver transplanted (LT). Reported HEV seroprevalence rates in general populations of Europe and the United States are 5-12% and 19%, respectively. Reported HEV RNA detection rates are remarkably lower, however, being 1.4% in Europe and 0.12% in Japan. We evaluated the HEV seroprevalence and RNA detection in post-LT patients to evaluate the hypothesis that HEV may pose potential subclinical risk in this particular immunocompromised patient population. Method: 106 post-LT patients were enrolled and provided blood and feces samples. All patients were tested for HEV seroprevalence. After exclusion of acute/chronic HEV cases (n=3) and other unavailable cases (n=13), 91 post-LT patients were investigated for HEV serology (IgG and IgM) and HEV RNA detection (serum and feces) every 4 months during 1-year follow-up period. All patient samples were kept in -70C storage. HEV RNA in serum and feces were detected by real-time (in-house) RT-PCR technique (lowest level of detection=10 IU/mL). Demographic and clinical data were retrieved from the medical records for descriptive statistical analysis. Result: The 106 post-LT patients had an HEV seroprevalence of 53.8%. After exclusion of the unavailable cases, 91 post-LT patients were prospectively investigated. HEV seropositive group was 50.5%, while the seronegative group was 49.5%. Baseline characteristics between two groups were not different. The serum and feces HEV RNA detection at baseline in seropositive group were 5/46 (21%) and 1/46 (2%), respectively. In seronegative group, the serum and feces HEV RNA detection were 2/45 (4.5%) and 3/45 (6.7%), respectively. Due to unprecedently high in proportion of patients with positive serum HEV RNA in both groups at the 4th visit, we decided to report our prospective result of the 8-month follow-up period. In seropositive group, serum and feces HEV RNA were detected in 11/46 (24%), 3/46 (6.5%), respectively. In seronegative group, serum and feces HEV RNA were detected in 9/45 (20%), 4/45 (8.8%), respectively. During 8-month period, 8 out of 14 and 8 out of 13 more cases of positive HEV in serum or feces in patients with and without IgG (+) were newly discovered, respectively. 2 out of 27 patients with positive serum or feces HEV RNA had abnormal liver function tests and one case was proved to be from anastomosis stricture with intrahepatic stone which was relieved after underwent ERCP. Conclusion: Thailand has high prevalence of HEV seroprevalence in post LT patients. Post-LT patients could have subclinical HEV infection without obvious clinical clues. Without HEV RNA assays, active HEV infection could be missed even in HEV IgG seronegative patients. Feces HEV RNA detection adds on benefit of the diagnostic yield. However, clinical significance of these silence detection remains to be elucidated

Authors:   , Sripan Donlaporn
Published: November 2023

Metagenomics is a useful technique to study microbial diversity directly in a culture-independent manner. Thus, metagenomics finds nearly 100% of all microorganisms in the environment. This approach becomes a major tool to analyze the microbial diversity (microbiota) worldwide. This research studied the diversity of microbial populations, including prokaryotes and eukaryotes, in the central Gulf of Thailand, using metagenomics combined with 16S and 18S rRNA gene sequencing. The research area covers various geographic coordinate throughout the central Gulf of Thailand, at the sea surface (<5 m from the sea surface) and a seafloor (1 m above the seafloor), during March to April (dry season) of 2013. The communities, both prokaryotes and eukaryotes, were determined homogeneous, by the function of the program Mothur (get.communitytype). Yet, some abiotic factors were found to affect the prokaryote population: temperature (p=0.012) and for eukaryote population fluorescence Seapoint (p=0.029) and salinity (p=0.004). Significant representative OTUs in prokaryotes were Pseudoalteromonadaceae and Oceanospirillacea; and eukaryotes were Bilateria, Euglenida, and Cnidaria. Moreover, the direction of water circulation and the type of organisms might affect the microbial diversity, observed possible correlation in PCoA. Overall, this research successfully studied the microbial diversity of the dry season; meanwhile does not represent other seasons. Therefore, it is advisable to also study the diversity of microbes in other seasons as well.
Biological activity of 5-hydroxy-3,7-dimethoxyflavone from kempferia parviflora wall. Ex. Baker in saccharomyces cerevisiae and human hepatoma cell line HepG2
Authors:   , Suanmali Nattanich
Published: November 2023

Calcium signaling pathways play important roles in regulation of cellular processes in eukaryotes ranging from yeast to human. Because of the high degree in gene conservation from yeast to human, the small molecule inhibitors effectively function in yeast might exert their function in human as well. Our previous studies using a ∆zds1 yeast-based assay could identified a flavonoid 5-hydroxy-3,7-dimethoxyflavone (5-OH-3,7-DMF) from Kaempferia parviflora Wall. Ex. Baker showed inhibitory activity against the Ca2+-signals in the mutant yeast YNS17 strain (Δ zds1). This study aimed to investigate biological activity of 5-OH-3,7-DMF related to calcium signaling pathways. Genetic analyses in several mutant yeast strains showed that Mck1, a protein kinase in the calcium signaling pathway, was the molecular target of the 5-OH-3,7-DMF.  Yeast MCK1 is an ortholog GSK-3β gene coding for glycogen synthase kinase-3β in human. There were many reportes on the relationship between high expression level of GSK-3β and several pathogenesis including type 2 Diabetes and Alzheimer’s disease. 5-OH-3,7-DMF showed in vitro inhibitory activity against GSK-3β with an IC50 values of 9.72 ± 0.15 µM with 85.6 ± 7.41 % of inhibition. Interestingly, 5-OH-3,7-DMF showed ATP non-competitive binding mode to GSK-3β by Dixon plot (Ki = 13.04 μM) and substrate competitive binding mode to GSK-3β by Dixon plot (Ki = 53.92 μM). The treatment of insulin-resistant HepG2 cells model with crude extracted of K. parviflora (CE) or 5-OH-3,7-DMF caused a decrease in G6Pase gene expression and only 5-OH-3,7-DMF could recover glycogen levels through decreasing phosphorylation of glycogen synthase (GS) protein. Moreover, when the cells grown in high glucose-high insulin (HGHI) medium treated with 5-OH-37-DMF, phosphorylation of GSK-3 was abolished as comparable values to those of controls (LiCl and GSK-3β inhibitor I). These findings indicated that 5-OH-3,7-DMF might be a potential GSK-3 inhibitor that  modulates the glucose homeostasis and might be potential for type II diabetes drug development.
Screening of bioactive compounds produced by streptomyces spp. Isolated from eastern honey bee (apis cerana) and stingless bee (tetragonula laeviceps)
Authors:   , Tangwichai Orapun
Published: November 2023

In recent years, antibiotic-resistant pathogens have been increasing faster than the numbers of new therapeutic compounds entering clinical use, thus the search for new antibiotics is in need. Apart from diseases caused by pathogenic microorganisms, obesity and overweight are linked to deaths worldwide. The search for drugs that can reduce the number of fat cell is also necessary in public health. One of the widespread sources of antibiotics is Actinomycetes, especially Streptomyces genus. Streptomyces spp. have been extensively isolated from soil but the discovery of novel compound is rare. Therefore, Streptomyces isolation from rare niche, i.e. symbionts of insects, could potentially lead to the discovery of novel bioactive compounds. In this study, Eastern honey bees (Apis cerana) and stingless bees (Tetragonula laeviceps) were used as sources to isolate Streptomyces and total of 125 isolates were obtained from internal and external. We found that five isolates produced the metabolites with broad antimicrobial activity against tested species of Gram positive bacteria, Gram negative bacteria and yeast. The phylogenetic tree based on 16s rRNA gene sequences showed high similarity with previously discovered microorganisms. Moreover, the results implied that the evolution which Streptomyces spp. isolated from the same insect were not root together. We have investigated the effects of the crude metabolites on preadipocytes cell line 3T3-L1 differentiation and found that crude extracted from I-EHB-18, closely related to Streptomyces andamanensis sp. Nov, inhibited adipocyte differentiation of 3T3-L1 cells at the early stage of differentiation with no acute cytotoxicity. Detailed study revealed that this crude extract suppressed expression of Peroxisome proliferator-activated receptor gamma (PPARγ), a master regulator of adipocyte differentiation. This is the first report of bioactive compound possessing anti-adipocyte differentiation activity produced by Streptomyces isolated from Eastern honey bees. Hence, the result may lead to a new compound for developing therapeutic drugs in the future.

Authors:   , Boubpha Sysouvanh
Published: November 2023

Bioremediation is an effective, low cost and environmental friendly technique to clean up crude oil-contaminated environment. This study aimed to develop the ready to use liquid bacterial formulation of petroleum hydrocarbon-degrading Exiguobacterium sp. AO-11 which was isolated from marine sediment, for bioremediation of crude oil contaminated-seawater. Strain AO-11 was evaluated for the degradation of crude oil in various environmental conditions. The results revealed that this strain could degrade crude oil in various environmental conditions including pH 6 to 9, salinity 8 to 45.4 ppt, temperature 25 to 37oC and crude oil concentration 0.25 to 1.5% (v/v). In order to reduce the cost of bacterial formulation, agro-industrial byproducts, soybean oil mill dry sludge 15% (w/v) (SB) in 1:4 diluted seawater based medium was used for bacterial cultivation and it could enhance bacterial cell growth from 6.07±0.06 Log CFU/ml up to 8.6±0.02 Log CFU/ml in 9 hours. For preparation of liquid formulation, phosphate buffer was selected as a suitable suspension solution which could preserve AO-11 survival at 86.7±1.4% in 30 days and maintain crude oil degradation in liquid cultivation at more than 80%. Protective agent (PEG 1%) was selected for prolonged storage and it could preserve AO-11 up to 72.4±0.2% and 58.7±0.7% at 4ºC and 30ºC in 60 days, respectively. The preliminary estimation of the costs of AO-11 liquid formulation was at 68 baht/L. Moreover, 30-day stored AO-11 formulation could degrade 0.5% (v/v) crude oil in seawater up to 61±5.2%. This study revealed the potential of using agro-industrial waste based cultivation medium for bacterial cell production. Furthermore, liquid bacterial formulation was developed and it has potential to be used for bioremediation of crude oil-contaminated seawater.

Authors:   , Kramyoo Min
Published: November 2023

Influenza A pandemic 2009 H1N1, influenza A H3N2, and influenza B have all been in circulating in Thailand. The data indicate increasing influenza like illness as reported by the Thai National Influenza Center every week. Adamantane an M2 channel blocker and Neuraminidase inhibitors (NAIs) are two classes of antiviral that are available for medical health care. Influenza A resistance to Adamantane drugs is greater than 99% worldwide leaving NAI agents as the only class which the World Health Organization (WHO) recommends for treatment. Oral Oseltamivir is the most commonly used agent worldwide, but many European countries have found Oseltamivir resistance emerging and spreading around the world. Pyrosequencing is a rapid and high throughput method for screening gene markers associated with antiviral susceptibility whereas, the NAI assay is a tool for monitoring phenotypic antiviral resistant by cell culture. Antiviral resistant influenza virus surveillance reports are limited in Thailand. This study was designed to determine the distribution of antiviral resistant influenza virus in Bangkok, Thailand by comparing the results of pyrosequencing and the NAI assay. All seasonal influenza A samples tested had genetic markers consistent with known resistance markers to Adamantane but were still susceptible to Oseltamivir. Both genotypic and phenotypic results showed that Oseltamivir was effective against all influenza viruses in this study. Although antiviral resistance surveillance of influenza virus in Thailand has found a very low percentage of resistant strains the use of Oseltamivir to treat influenza patients should still be monitored and continued surveillance of influenza for resistance in recommended.
Development of supramolecular structuredbenzoxazine dimers and their potential applications
Authors:   , Sutapin Choltirosn
Published: November 2023

The present work focuses on molecular design and development of benzoxazine dimer structures for their potential applications. In the first part, a series of N,N-bis(2-hydroxybenzyl) alkylamine, so called benzoxazine dimers, are prepared via a simple and selective ring-opening reaction of benzoxazines with the yield as high as 90%. These compounds perform dual functions as initiator and catalyst for ring-opening polymerization of lactide. Two hydroxyl groups of benzoxazine dimers are initiated by organocatalyst to be initiator. By simply varying methylene bridge, very active ligands for alkyl/alkoxide aluminium complex formation can be clarified. Metal-ligand complexes are proved to be catalysts in ring-opening polymerization of lactide. Polylactides obtained are polymerized with narrow polydispersity index and well controlled molecular weight. In the second part, for the first time, a thermochromic free-standing poly(ʟ-lactic acid) film is studies. By simply constructing tetra-branched benzoxazine dimers from pentaerythritol followed by ʟ-lactide ring opening polymerization initiated by organocatalyst as well as the conjugation with diacetylene at terminal, a precise eight-armed poly(ʟ-lactide) conjugated diacetylene can be obtained. The blend with poly(ʟ-lactic acid) followed by solution casting leads to the thermochromic free-standing film. The comparative studies declare that bulk diacetylene and other linear-, four- and multi-armed poly(ʟ-lactide) terminated polydiacetylene do not show thermochromic property. The microstructure analysis indicates the symmetric eight-armed structure controls the packing of polydiacetylene in poly(ʟ-lactic acid) matrix upon heating and cooling. From these two works, the benzoxazine dimers can be noticed to be one of the choices for decorating star and/or multi-branched polylactide. In the final part, the work covers a convenient, environmentally friendly, and simple procedure to obtain benzimidazoles through the cyclization between aldehyde and phenylenediamine derivatives under reduced pressure. This synthesis pathway not only gives the benzimidazoles with high yield from the mild condition but also the selection of benzaldehyde and phenylenediamine with reactive functional group leads to the precursor for synthesis a new class of benzoxazine dimer with pH-sensitive fluorescent intensity and multichromatic emissions.
NANOSTRUCTURAL INVESTIGATION AND ENGINEERING OF ELECTRODEPOSITED ZINC COATINGS AND THEIR CHROMIUM AND GRAPHENE-BASED PASSIVATION LAYERS
Authors:   , Jantaping Narin
Published: November 2023

Electrodeposited zinc is an important type of coating used widely for corrosion protection in various applications. Nevertheless, the understanding on the relationships between coating fabrication process, micro/nanostructure, and properties of the material is rather limited. This thesis aims to develop structure-corrosion property relationship frameworks for the electrodeposited zinc coating and its chromium conversion layer, and also explore the novel process, particularly top-coating of graphene, upon which the corrosion resistance of the zinc coating could be enhanced. The research works performed in this thesis are divided into 3 parts: (i) the processing-structure-property relationships in electrodeposited zinc, (ii) the effects of the EZ’s structure on the formation of Cr(III) passivation, and (iii) the feasibility of graphene-based coatings as a potential for protecting corrosion. A set of environmentally friendly alkaline non-cyanide zinc coatings with and without trivalent chromium passivation is prepared by the electrodeposition process for examination of their micro/nanostructure and corrosion properties. Three groups of plating additives are employed to modulate the structure of the galvanized coating. Using a suite of modern characterization techniques, including field emission scanning electron microscopy (FE-SEM), X-ray diffractometry (XRD), focused ion beam (FIB), and transmission electron microscopy (TEM), it is determined that texture and interfacial defects which are controlled by additive incorporation play critical role in controlling the corrosion behavior of the coatings. Furthermore, polyquaternary amine salt is identified as an effective additive for zinc plating as it helps promotes a formation of a relatively thick amorphous-oxide phase in the chromate film resulting in high resistance to corrosion. Finally, the feasibility study of graphene-based top coatings for corrosion shows that graphene can be coated onto a substrate using the electroplating setup. The coating of graphene is found to be controlled by additives, applied current density, and deposition time. The resulting graphene coating shows appreciable corrosion resistance results, and thus it is promising to be used for top-coating of electrogalvanized zinc.
FABRICATION OF NANOSTRUCTURED ZINC OXIDE VIA ELECTRODEPOSITION AND HEAT TREATMENT
Authors:   , Wanotayan Thanyalux
Published: November 2023

Zinc oxide is a promising material used as a photocatalyst to treat organic contaminants in water. To obtain good photocatalytic activity in the film, porosity and high surface area are often promoted. In this work, a systematic study of the fabrication process of nanostructured zinc oxide thin film via electrodeposition and heat treatment is carried out. The process-structure-property relationship of both zinc and zinc oxide films are investigated. This research is divided into three parts. In the first part, the effects of current density and additives on the structure and property of zinc film are studied. Both current density and additives play an important role in controlling the structure of the zinc film and also in the formation of zinc oxide. Additives influence the texture development of the deposits and in turn influence the corrosion resistance in the coatings. Upon applying a direct current of 2 A/dm2 with no additive, sub-micron zinc rods that are intertwined and formed clusters of granules is observed. In the second part, the effect of heat treatment temperature on the structure and surface morphology of zinc oxide thin films are analyzed. The oxidation reaction both below and above the melting point of zinc metal are studied. For temperature below the melting point, ZnO nanoneedle is formed and grown using the zinc deposit structure as a template. However, spherical ZnO particles agglomerate as parts of the rod structure for temperature above the melting point. In the third part, ZnO thin film with different surface morphologies is tested for the photocatalytic property. ZnO thin film annealed at 500°C shows the best photocatalytic activity in degrading MB dyes under UV light irradiation. This may be attributed to the higher surface area of the film. In conclusion, nanostructured ZnO thin film with good photocatalytic property can be synthesized from electrodeposition and heat treatment method.

A Discourse on Sufis'Approach to the Application of Hadíth
Authors: Yusuph  , Dauda Gambari
Published: November 2023

Ḥadīth, as the second primary source of Islam, is shrouded in many issues. Its application among the Sufis has attracted an array of attention. This is because they (Sufis) appear not to be in absolute compliance with the conventional methods of ḥadīth narration, authentication and application as put in place by Muḥaddithūn and widely used by scholars, especially the Salafiyyah. This study examines the Sufis’ approach to the usage and application of ḥadīth, especially their adherence to the rules of ḥadīth authentication. The analytical method of research is adopted in this study. It avails the opportunity to analyse various texts and scholars’ submissions on the science of ḥadīth as related to this study. It is, therefore, discovered that the Sufis, in most of their applications of ḥadīth, downplayed the rules as set by Muḥaddithūn due to their belief that the Prophet is still alive, even after his demise, and that direct link or connection with him is possible. So, they do not need stringent conditions to establish a report from the Prophet or act on it. It is also discovered that the bulk of narrations at the Sufis’ disposal are considered to be of weak or fabricated status. However, ḥadīth of the weak category can still be applicable in the realm of meritorious acts (faḍā’il), according to majority of the scholars. It is also discovered that some Sufis hold that as long as a particular narration does not contradict the principles of Islam, ascribing such to the Prophet should be less controversial. This, therefore, concluded that Sufis flouted the rules of ḥadīth authentication with good intentions and attached importance to their propositions to make them gain wider acceptance from the people.
Religiosity and Righteousness: A Critique of Islamic and Christian Practices on the University of Ibadan Campus
Authors: Oladosu Uthman Habibat
Published: November 2023

As it is in the larger Nigerian society, the University of Ibadan campus is replete with religious groups and associations with affiliation to Islam and Christianity. Contrary to the fundamental dictates of these two religions however, the history of relationship between the Muslim and Christian communities on campus has been circumscribed, in the main, by suspicion, hatred and, sometimes, outright conflict. The gulf between religious texts and practices on Ibadan campus is equally manifest among Christian and Muslim students some of whom have been found guilty of examination malpractices, cultism and illicit sexual relations among other acts that both Islam and Christianity have designated as acts of unrighteousness. This paper, therefore, sets out to achieve the following: a) interrogate the concept of righteousness in both Islam and Christianity and, b) situate the latter against the general notion of religiosity on Ibadan campus. The paper relies heavily on the assumption that religious activism should be an instrument of character building and a catalyst for peaceful coexistence. The paper uses the descriptive method in eliciting data and sources its theoretical discussion from existing literature on the subject. The paper finds the following questions very important: exactly how does religiosity on the University of Ibadan campus translate to righteousness? How do we account for intra/inter-religious conflicts that often occur on the campus despite the outward display of religious identities by all? In other words, how far has the manifestation of religious identities by Muslims and Christians on the Ibadan campus been useful for the enhancement of godliness? This paper concludes that both Islam and Christianity, when properly understood and their tenets carefully applied, have models that can guarantee the establishment of righteous and godly society for the Nigerian nation at large.
The Voyage to Sharī‘Ah Stardom in Western Nigeria; The Case of Fatwa House, Kishi, Nigeria
Authors: Abdulwahab Danladi Shittu  , Sodiq Sunkanmi Mustapha
Published: November 2023

Every society strives for justice, but the means to achieve it vary. In Nigeria, the criminal code is the law of the land in the south, while the penal code is used in the north, along with Islamic criminal law. The penal code was later replaced by the Sharī‘ah penal code in some Muslim-majority states, such as Kano and Zamfara. Due to the Muslim minority in the south, this innovation could not be extended there. As an alternative, Muslims in some southern cities have formed Islamic conflict resolution committees, which lack constitutional backing for trying criminal cases and cannot impose appropriate punishments for such offences tried. This study investigates the strength of the Fatwa House in Kishi, Oyo State to confirm its relevance. The study used a combination of historical, content analysis, and descriptive survey research methods to collect and analyze data. The historical method was used to provide an overview of Shariah in Southern Nigeria. Content analysis was used to study the formation and legislative functions of the Fatwa House in Kishi, while descriptive analysis was used to study and analyze the data collected and the collection procedures. The research confirmed that the Fatwa House has been successful in curtailing social vices in Kishi through the use of reprimand as the main punishment for offences tried by the committee. The study also found that the Fatwa House is well-respected by the Muslim community in Kishi and its surrounding villages. Based on these findings, the study recommends that the Fatwa House should work on extending its reach to surrounding villages and arranging for hearings to be held in those villages. This would allow the Fatwa House to provide an alternative to the conventional court system for Muslims in the region.
Communicative Language Approach (CLT) to the Teaching and Learning of Arabic Language in Nigerian Universities

The most recent and effective method of teaching second or foreign language is Language Communicative Teaching (CLT). It emphasizes interaction as both the means and the ultimate goal of learning a language. It is also referred to as “Communicative Approach”. Moreover, the 12th edition of the National University Commission (NUC) encourages Arabic teachers to adopt (CLT) approaches in their methodology of teaching. Therefore, this research intends to find out the level of compliance of lecturers in the Nigerian universities to this instruction. This research is qualitative in nature. Observation and document analysis were conducted to scrutinize the teaching methods as well as the language theories the teachers used in the classroom. The two Lagos State owned universities offering Arabic language as a course of study were selected as a case study. The field notes-based universities on the observation were used to analyze the teachers’ compliance with the CLT principles. The result shows that none of the classes observed adopted CLT approach in their teaching methodology. The study identified the necessary implications of second language teaching without Communicative Approach and suggests ways the approach can lead to an effective teaching of Arabic language in Nigerian institutions of higher learning.
A compartmental fractional-order mobbing model and the determination of its parameters
Authors: Işık Engin , Daşbaşı Bahatdin
Published: November 2023

In this study, a mathematical model is presented with fractional-order differential equations in the Caputo sense that examines the time-dependent changes of variables representing individuals who are exposed to mobbing, individuals who are not exposed to mobbing, or individuals who gained resistance to mobbing, and individuals who practice mobbing. Existence and uniqueness, and boundedness and non-negativity of the solutions of the proposed model are examined. Additionally, the data set containing the time-dependent changes of these variables has been used as a basis to examine the dynamics in a population. By the data set, the approximate results of 9 different parameters used in the proposed mathematical model with ODE have been found with the lsqcurvefit function. The parameters obtained from the ODE system are rewritten into the proposed fractional model, and the value of the derivative order that gives the minimum error has been investigated. The related Matlab codes are presented in the study. Also, while it is observed that a decrease occurs in the number of individuals exposed to mobbing, there is an increase in the number of individuals who are not exposed to mobbing or who gain resistance to mobbing and individuals who practice mobbing. All the obtained results are shown in graphical detail.

Der Do-not-Track-Standard soll das Problem umfangreicher Profilbildung im Netz reduzieren. Jetzt liegt ein Standard vor. Das Ziel ist aber nicht erreicht. Selbstregulation funktioniert nur mit Druck des Gesetzgebers. Erst kürzlich hat das W3C eine Vorabfassung seines „Do not track“-Standards vorgelegt. Allerdings ist unterdessen Yahoo aus der Initiative ausgetreten.
