Authors: Uche Nkechinyere J. , Okoye Onochie , Kizor-Akaraiwe Nkiru , Chuka-Okosa Chimdi , Uche Enoch O. 
Published: November 2023

Background
Genomic research advances the understanding of human health and disease. It also drives both the discovery of salient genetic association(s) as well as targeted screening, diagnostic and therapeutic strategies. Human subject participation is crucial for the success of genomic research.

Methods
This is a cross sectional analytical study conducted at two tertiary centers in Enugu Southeast Nigeria. Semi structured questionnaires were administered to eligible consenting participants. Data on their demographics, willingness to participate in genomic research and motivation for participation were obtained. Data was analyzed using Stata version 17 and summarized using median, frequencies and interquartile range(IQR). Associations between covariates were evaluated with Chi square test and multivariable logistic regression.

Results
Among 228 glaucoma subjects who participated in our study,119(52.2%) were female and 109(47.8%) were male. The median age was 64 years(IQR = 50–76). Although 219 (96.0%) participants expressed willingness to participate in a glaucoma genetic study, only 27(11.9%) of them will be willing to participate if there will not be feedback of results to participants (χ2 = 18.59, P<0.001). No participant expressed willingness to submit ocular tissue samples. Majority (96.2%) of subjects will not participate if the intended research required submission of body samples after death. Desire to know more about glaucoma (63%) was the most common reason for participation. In a multivariable logistic model, subjects between 61–90 years (p = 0.004, OR = 7.2) were 7 times more likely to express willingness to participate in glaucoma genetic research after adjusting for other covariates when compared to subjects aged 41–60 years. Other covariates did not influence participants’ willingness.

Conclusion
Glaucoma subjects are more likely to be willing to participate in genetic research, if they would receive feedback of results. Willingness to participate in genetic research is significantly associated with age.

Limitations
We did not evaluate the salient options for feedback of results to participants in our study.

INTRODUCTION:
A substantial proportion of patients with esophageal adenocarcinoma (EAC) do not report gastroesophageal reflux disease (GERD) symptoms. This study aimed to compare the risk factor profiles and cancer stage at presentation of patients with EAC with and without prior GERD.

METHODS:
In this retrospective cross-sectional study, patients with EAC were divided into 2 cohorts: (i) EAC with prior GERD: patients who reported typical GERD symptoms (heartburn or regurgitation) ≥1 year before cancer diagnosis and (ii) EAC without prior GERD: patients who did not report prior GERD symptoms or reported symptoms within 1 year of their cancer diagnosis. Baseline demographics, risk factors, and cancer stage at presentation were compared between the 2 cohorts. In addition, the distribution of patients based on numbers of BE/EAC–associated risk factors (1, 2, 3, 4, and 5 or more) was examined in the symptomatic and asymptomatic cohorts.

RESULTS:
Over 13 years, 388 patients with EAC with prior GERD and 245 patients with EAC without prior GERD were recruited. Both groups had similar baseline demographics and risk factors, but patients with EAC with prior GERD were more likely to have a history of BE. Asymptomatic patients had more advanced disease. Patients with 3 or more BE/EAC–related risk factors formed the largest proportion of patients in both the symptomatic and asymptomatic cohorts.

DISCUSSION:
Patients with EAC with and without prior GERD symptoms are phenotypically similar, suggesting that BE screening efforts to prevent or detect early EAC should not be restricted to just those with GERD.
Does Bitcoin Affect Term Deposits? Evidence from MINT Countries
Authors: Baş Tuğba , Özaydın Orhan , Dura Yahya Can 
Published: November 2023

Abstract
This article examines the relationship between Bitcoin volume and term deposit investments in Mexico, Indonesia, Nigeria, and Turkey (MINT) from 2016 to 2021. We run cointegration and error-correction econometric models for each country, analyzing both the long-term and short-term interactions between Bitcoin volume and time deposits. Our findings indicate a negative association between Bitcoin volume and term deposits in all the MINT countries, except Mexico. This suggests that individual investors in economically and financially unstable nations are increasingly turning to Bitcoin as an alternative investment option. The observed effects, while currently modest, highlight the potential threats posed by decentralized cryptocurrencies to the monetary systems of emerging economies, impacting the stability of the banking industry and overall economic growth.
Effect of process parameters on mechanical properties and wettability of polylactic acid by fused filament fabrication process
Authors: Nagam Vinoth Babu , Narayanan Venkateshwaran 
Published: November 2023

Abstract
Fiber-reinforced composites have changed additive manufacturing into a sustainable manufacturing paradigm with the capacity to produce items with outstanding mechanical performance. The fused filament fabrication (FFF) process is the latest in advanced digital fabrication techniques used for fabricating polymer material using additive layer deposition. In this study, the results of mechanical and vibration tests were used to examine the impact of process variables such as layer thickness (0.08 mm, 0.25 mm, and 0.64 mm), infill density (20 %, 40 %, 60 %, and 80 %), and infill pattern (rectilinear, triangular, and hexagonal). The novelty of this work is to correlate the contact angle measurement with the mechanical properties of the 3D-printed specimens. The adhesion behaviour of the 3D printed parts is examined by measuring the contact angle from the wettability test. From the findings, it was observed that the infill density and layer pattern play a significant role in the interlayer adhesion, as evident from the contact angle measurement.
Die Zeitschrift Info DaF im Zeitraum 1980–1989: Eine spielerische Spurensuche
Authors: Schewe Manfred 
Published: November 2023

Zusammenfassung
Vor dem Hintergrund seiner mit Info DaF eng verknüpften Berufsbiografie sucht der Autor in den Beiträgen der 1980er Jahre nach Spuren von „Spiel“. Das zunehmende Interesse an „Spiel im Unterricht“, etwa an Lern- und Rollenspielen, erklärt sich durch den Einfluss der kommunikativen Didaktik, in der die Übernahme von (Sprecher- und Sprecherinnen-)Rollen zentral wird. Videos avancieren zu einem beliebten Medium und die Aufmerksamkeit richtet sich auf die – auch für Spielprozesse besonders relevante – Fertigkeit Hör-Sehverstehen. Gegen Ende der 1980er Jahre entsteht ein besonderes Interesse an der Kunstform Theater, die Dramapädagogik beginnt im Fach DaF eine wichtige Rolle zu spielen.

Abstract
The ever-growing demand for miniaturized optical systems presents a significant challenge in revolutionizing their core element – the varifocal lens. Recent advancements in ultra-thin, tunable metasurface optics have introduced new approaches to achieving zoom imaging. However, current varifocal metalens have faced challenges such as low focusing efficiency, limited tunability, and complicated designs. Here, we employ the high-contrast transmit arrays (HCTA) structures to design and fabricate a polarization-independent, single-layer flexible metalens that operates at a wavelength of 940 nm. Using a uniform stretching system, we characterized its optical performance to achieve over 60 % focusing efficiency within a 0 %–25 % stretch range, while the focal length changes align with theoretical predictions. Furthermore, our research also successfully demonstrated the capacity of a metalens with a numerical aperture (NA) of 0.5 to efficiently adjust imaging magnification within a 2× range, achieving imaging results that approach the diffraction limit. This research offers promising prospects for the practical use of compact and miniaturized optoelectronic devices in fields like photography, mixed reality, microscopy, and biomedical imaging.

Abstract
In order to solve the coordinated operation of voltage and frequency of microgrids and achieve effective distribution of output power, we propose the application of fractional-order nonlinear equations in coordination. This method designs a distributed impulse coordinated control strategy, to achieve the coordinated operation of the system. The distributed coordinated control structure and mathematical model are established, and the distributed two-level coordinated control strategy of the microgrid system is adopted. Aiming at the secondary control problem of microgrids, a distributed coordinated control protocol is designed. The results showed that after adding the distributed second-level coordination control of frequency at 3 s, the output active power of the four distributed power sources in the microgrid model is maintained to an evenly divided state after about 1 s. The output voltage and frequency utilizing the microgrid’s decentralized power supply quickly reach the ideal reference value, within the allowable error range, the output of the system can achieve coordinated control, and the active power can be distributed proportionally.

Abstract
There is growing interest in the transformation of costly, unsustainable feed systems to help address malnutrition and food insecurity in sub-Saharan Africa (SSA). In the poultry production industry, dietary insect meals were identified as a possible solution to aid in transforming poultry feeds by replacing expensive and environmentally threatening protein feed ingredients including soyabean and fish meal. Hence, playing an important role in helping to feed the ever-growing human population size through the production of more poultry meat and meat products. The potential of edible insects as highly nutritious, cost-effective, and biofriendly alternative protein feed ingredient in poultry diets is currently one of the most trending topics in animal nutrition worldwide. This review will provide a recent overview of the utilisation of insect-based diets by poultry-producing farmers in SSA, to improve poultry production at low costs with little effect on climate change. Therefore, the perspectives of various farmers towards using insect-based diets in poultry production; recent findings on the effect of insect-based diets on poultry production and performance; benefits of insect-based poultry meat; adoption and awareness of insect farming; and opportunities and constrains of rearing insects for animal feeding in SSA were discussed. Hence, there is still a need to improve insect farming infrastructure, educating and training insect and poultry-producing farmers on insect rearing and marketing, enforcing laws and policies on insect farming operation, investing and conducting more research on local insects in poultry diets, as well as conserving wild insects and the environment in general.
Verlustrücktrag bei der Gewerbesteuer? Eine Mikrosimulation der Aufkommenseffekte
Authors: Koch Reinald , Langenmayr Dominika , Schön Lena 
Published: November 2023

Zusammenfassung
Wie viele andere Länder auch hat Deutschland als Reaktion auf die von der COVID-19-Pandemie ausgelöste Wirtschaftskrise die steuerliche Verlustverrechnung verbessert. Jedoch blieb die Gewerbesteuer, die rund die Hälfte der Steuerbelastung auf Unternehmensgewinne ausmacht, von dieser Maßnahme ausgenommen. In diesem Beitrag analysieren Reinald Koch, Dominika Langenmayr und Lena Schön mithilfe einer dynamischen Mikrosimulation die potenziellen Auswirkungen eines Verlustrücktrags bei der Gewerbesteuer auf das Steueraufkommen. Wie sich erweist, kann sich die Einführung eines Verlustrücktrags mittelfristig größtenteils selbst finanzieren; kurzfristig kommt es allerdings zu Aufkommenseinbußen von durchschnittlich 7 Prozent. Es zeigt sich eine große Heterogenität zwischen Gemeinden, wobei strukturschwache Gemeinden oder Gemeinden mit niedrigem Gewerbesteueraufkommen besonders viel Aufkommen verlieren. Die Ergebnisse verdeutlichen den Reformbedarf der Gewerbesteuer.

Published: November 2023

Zusammenfassung
Der folgende Beitrag stellt die Ergebnisse einer explorativen Studie zur Rechtskenntnis der österreichischen Bevölkerung im Bereich der Grundrechte vor. Dabei wird sowohl der Stand der Forschung aufgearbeitet als auch auf historische Besonderheiten der lokalen Rechtskultur eingegangen. Die empirische Analyse legt den Schluss nahe, dass das Wissen über derartige Rechtsansprüche – trotz ihrer fundamentalen Bedeutung – bemerkenswert gering ist. Die Studie zeigt zudem eine Reihe an methodisch-formalistischen Schwierigkeiten, die den rechtssoziologischen Wesensgehalt dieses Forschungsbereichs spezifisch zu kennzeichnen scheinen. Darüber hinaus werden weitere Maßnahmen zur Behebung des festgestellten Defizits skizziert. Der Beitrag schließt mit einem Plädoyer für die gesellschaftspolitische Bedeutung und Notwendigkeit verfassungsrechtlicher Kenntnisse in einem demokratisch-liberalen Rechtsstaat.

Abstract
Cornejo-Daza, PJ, Villalba-Fernández, A, González-Badillo, JJ, and Pareja-Blanco, F. Time course of recovery from different velocity loss thresholds and set configurations during full-squat training. J Strength Cond Res 38(2): 221–227, 2024—The aims of the research were to examine the effects of (a) velocity loss (VL) thresholds and (b) set configuration, traditional or cluster, on time-course recovery. A randomized cross-over research design was conducted, in which 15 resistance-trained men performed 4 protocols consisting of 3 sets of 70% 1RM in full squat (SQ), differing in the VL incurred during the set assessed with a linear velocity transducer: (a) 20% (70-20), (b) 30% (70-30), (c) 40% (70-40), and in the set configuration (d) 20% of VL using a cluster methodology (70-CLU). Movement velocity against the load that elicited a 1 m·s−1 velocity at baseline measurements (V1-load) in SQ, countermovement jump (CMJ) height, and sprint time in 20 m (T20) were assessed at baseline (Pre) and postintervention (Post, 6 hour-Post, 24 hour-Post, and 48 hour-Post). The 70-20 protocol resulted in fewer total repetitions than the other protocols (p = 0.001), whereas 70-CLU, 70-30, and 70-40 completed similar total repetitions. The 70-30 protocol significantly worsened T20 at 6 hours-Post, CMJ at 48 hours-Post, and V1-load at 6 hours-Post (p < 0.05). The 70-40 protocol significantly impaired T20 at 6 hours-Post, and CMJ and V1-load at 24 hours-Post (p < 0.05). No significant performance reductions were observed for 70-20 and 70-CLU at 6 hours-Post, 24 hours-Post, and 48 hours-Post. Protocols with higher VL resulted in more pronounced fatigue and a slower rate of recovery. Cluster sets (70-CLU) resulted in higher volume than protocols with a similar level of fatigue (70-20) and a quicker recovery than protocols with a similar volume (70-30 and 70-40).

Heterocyclic structures are the basic building blocks of many naturally occurring organic compounds that are important for the development of essential biological processes in plants and animals, including carbohydrates and vitamins. They are also widely used as raw material sources to produce pharmaceuticals. In this study, three ligands from the groups of benzopyrones (chromone-2-carboxylic acid) and hydroxypyrones (maltol and coumalic acid), and a newly prepared complex of copper(II) nitrate with maltol as a ligand were investigated for their ability to inhibit cell proliferation. For research purposes, a series of solutions of the tested materials were prepared at different final concentrations (10&lt;sup&gt;–5&lt;/sup&gt; mol dm&lt;sup&gt;–3&lt;/sup&gt;, 10&lt;sup&gt;–6&lt;/sup&gt; mol dm&lt;sup&gt;–3&lt;/sup&gt;, and 10&lt;sup&gt;–7&lt;/sup&gt; mol dm&lt;sup&gt;–3&lt;/sup&gt;), and then applied to a total of 7 selected cell lines, including one healthy cell line, while the others were tumour cell lines. The results of MTT cytotoxicity assay on the selected 2D cell models showed that none of the selected ligands exhibited antiproliferative activity at any concentration on any of the tested cell lines. The complex of copper(II) nitrate and maltol, in contrast to the tested ligands at the 10&lt;sup&gt;–5&lt;/sup&gt; mol dm&lt;sup&gt;–3&lt;/sup&gt; concentration, exhibited significant cytotoxicity as follows: KATO III &gt; HT-29 &gt; Hep G2 &gt; NCI-H358 &gt; MDA-MB-231 &gt; Caco-2 &gt; MRC-5. The healthy cell line (MRC-5) had a survival rate higher than 90.0 % at all tested concentrations, which led to the conclusion of the selectivity of the compound towards tumour cell lines.

Fresh Liang leaves, a local vegetable of Southern Thailand, were dried, seasoned, and fortified with different ratios of dried shrimp and sesame seeds at 1%–5% for making a rice topping product (Furikake) named as F1-F5. The F5 obtained the highest consumer acceptability with high calcium and phosphorus contents at 4,299.45 mg/kg and 3,436.32 mg/kg, respectively. Total phenolic content and DPPH radical scavenging antioxidant activity of F5 were 2,575.22 µg GAE/g DW and 676.99 µg TE/g DW, respectively. Total chlorophyll and carotenoid contents were 11.38 mg/g DW and 3.52 mg/g DW, respectively. An increment of aw and moisture content (p < 0.05) of the F5 kept at higher temperature storage was noticed, and a reduction of L* value under all storage conditions was noticed.
Relevance of Tea Shops and Cafes as Spaces for plot progression in Malayalam Cinema
Authors: K. Anaswara Krishna  , Shemin Balachandran Nair  
Published: November 2023

Currently One of the most significant mass media for communication and storytelling is film. The film uses images, music, and sound effects to convey creative ideas, concepts, and emotions. Through its capability for visual portrayal, films engage, comprehend, and influence audiences. This paper entitled ‘Relevance of Teashops and Cafes as Spaces for Plot Progression in Malayalam Movies’ studies how films especially Malayalam films use the space of teashops and cafes in movies as a space of plot progression. Even though these locations are a necessary component in the production of Malayalam films, the role of teashops and cafes in the making of a film is a less-explored topic. The concept of space is crucial to the creation of films. A perfect setting is necessary for conveying all of the essence of the movie to the audience as well as the core idea of the movie. The movie makes use of space for a variety of things, including setting up sets, filming scenes, and establishing distinct places. When Malayalam movies are taken into consideration the presence of a teashop or a cafe has always been an inevitable part. The locations of teashops and cafes were given a lot of attention in movie narratives, particularly in Malayalam films. In the atmosphere of these places, significant story developments and character growth take place. The teashop settings have been a major part of setting the overall tone and portraying the beauty of the film's setting in the majority of ancient Malayalam films. The cafes in the new Malayalam film function similarly by improving the mood of the film by creating lovely settings. The audience will be drawn to these locations as a result. The study attempts to provide a comprehensive understanding of the significance of teashop and cafe scenes in Malayalam films. The study focuses on the purpose of the teashop and café environments in the development of the story and other significant events in the film's narration. The study will use a qualitative methodology. Six major Malayalam films will be the subject of the analysis. For the study, a content analysis of six films from different periods that prominently featured cafe and teashop settings was chosen.
