Published: April 2024

The transition from education into employment is confronted with uncertainties and worries. Studies have been focused on investigating discrepancies between students’ skills and level of preparedness and the demands of the modern business landscape. However, little research has been done on the factors that contribute to these gaps on the individual level. The study aims to understand perceived dilemmas and describe strategies employed in the college-to-career transition. The phenomenological qualitative design was utilized, and five graduating psychology students were considered as participants in the study. Structured interview was used as the main research method and thematic analysis as the primary analytical tool. Based on the relevant findings, the study concluded that graduating psychology students perceive the shift toward the professional world as challenging and difficult as it is characterized by uncertainties and adjustments yet a fulfilling process that fosters a sense of hope that regardless of what the future holds, college have prepared them for the life that they are going to have after graduation. Additionally, the main career-entry worry of graduating psychology students in transitioning was finding a decent workplace coupled with the stressful urgency to land an entry-job position after graduation. Generally, graduating psychology students overcome these perceived difficulties by seeking work-based experiences to prepare themselves for how things work in the professional world and maximizing their time in the internship to expand their network. These findings would be of great benefit to the development of intervention programs that will better prepare students for the college-to-career transition.

Authors: Mazzone Paolo , Della Marca Giacomo , Sposato Stefano , Di Lazzaro Vincenzo , Scarnati Eugenio
Published: April 2024

Background: El núcleo tegmental pedunculopontino (PPTg) es un nuevo blanco para la Estimulación Cerebral Profunda (ECP) en la Enfermedad de Parkinson (PD), en particular para mejorar las anormalidades posturales y las alteraciones de la marcha. La técnica quirúrgica estereotáctica clásica, basada en la línea intercomisural Ca-Cp (comisura anterior-comisura posterior) y el esquema de Guyot, es difícilmente aplicable a la cirugía del tronco del encéfalo, debido al alto grado de variabilidad anatómica interindividual. Objetivo: Describir la técnica del modelo tridimensional, basada en neuroimágenes y atlas anatómicos, útiles en el planeamiento prequirúrgico así como también en las fases intraoperativa y postquirúrgica de implantación de electrodos de ECP en el PPTg en humanos. Métodos: Construimos modelos 3D, representando las estructuras anatómicas más relevantes del mesencéfalo y la protuberancia, en base a atlas estereotácticos anatómicos por medio de softwares Rhinoceros© y MedicoCad utilizados para la reconstrucción y el modelo 3D de estructuras del tronco del encéfalo. Los modelos 3D fueron integrados con neuroimágenes (imágenes de RM y TC, y particularmente enriquecidas con la representación de los vasos cerebrales por medio de TC angiográfica). Modelo tridimensional de estructuras mesencefálicas y protuberanciales: Se propone un abordaje para la identificación estereotáctica del núcleo tegmental pedúnculopontino. Resultados: Las estructuras anatómicas incluidas en el modelo fueron las siguientes: PPTg, Pedúnculo Cerebeloso Superior (SPC), Núcleo Peripeduncular (PPD), Lemnisco Medio (ML), Núcleo Rojo (RN), Ventrículos 3ro y 4to, Lamina Quadrigémina (LQ), Locus Coeruleus (LC), Sustancia Gris Periacueductal (PAG) . Discusión: La determinación clásica de las coordenadas estereotácticas, obtenida por medio del uso de un sistema proporcional, basado en ventriculografía o neuroimágenes, utilizando como referencia la línea Ca-Cp y el límite superior del tálamo, y adoptando únicamente atlas estereotácticos 2D, difícilmente pueda ser aplicada a la cirugía del tronco del encéfalo. El método “directo” de planificación, basado en MPR (reconstrucción multi plano) y cortes de exploración por TAC estereotáctica, en la superposición de cortes Ct 2D por individualización ‘directa’ de los bordes del tronco del encéfalo, y en la representación del PPTg, permite una mejor adaptación a los rasgos anatómicos individuales.

Evaluation of echocardiography and computed tomography characteristics related to aortic valve replacement technique through the right anterior thoracotomy at the 2nd intercostal space
Authors: Nguyen Tien Dong , Ngo Vi Hai , Nguyen Minh Ngoc , Nguyen Sinh Hien
Published: April 2024

Objective: evaluate echocardiographic and computed tomography characteristics related to minimally invasive aortic valve replacement technique through the right anterior thoracotomy at the 2nd intercostal space.
Methods: study on 74 patients undergoing aortic valve replacement surgery through the right anterior thoracotomy at the 2nd intercostal space at Hanoi Heart Hospital and 108 Military Central Hospital, from October 2019 to December 2022. Patients underwent preoperative echocardiography and multiple slices computed tomography to assess the lessons of aortic valve, valve annulus diameter, and intercostal space width.
Results: The ratio of aortic valve stenosis is 55.4%, stenosis combined with regurgitation is 31.1%, and aortic regurgitation is 13.5%. The average valve annulus diameter on computed tomography scans is 26.5 ± 3.1 mm (smallest 20; largest 36); average 2nd intercostal space width 18.1 ± 3.1 mm (smallest 11; largest 25). Valve annulus diameter measured by computed tomography correlates closely with actual prosthetic valve size (r = 0.54, p < 0.001); measured by echocardiography had a weak correlation and not statistically significant. The prosthetic valve size to be replaced is smaller than the valve annulus diameter measured on computed tomography, with an average of 4.8 ± 2.7 mm in aortic valve stenosis, 5.7 ± 2.0 mm in combined stenosis and regurgitation, and 7.2 ± 2.9 mm in aortic regurgitation, in which the difference between valve stenosis and regurgitation is statistically significant (p = 0.01).
Conclusions: Minimally invasive aortic valve replacement technique through the 2nd intercostal space right thoracotomy, with cutting the 3rd rib, is suitable for Vietnamese anatomy. Valve annulus diameter measured by computed tomography has a good linear correlation and can be a predictor for prosthetic valve size before surgery.

Authors: Oluka Alexander
Published: April 2024

The study investigates the impact of misinformation on taxpayers' tax compliance behaviour, aiming to uncover the psychological and economic repercussions on citizens. Employing a qualitative research methodology, the study conducted interviews with eight participants, followed by a thematic analysis to identify prevailing themes in taxpayer responses to misinformation. The findings reveal that misinformation significantly influences taxpayer behaviour, leading to stress, mistrust of tax authorities, and subsequent non-compliance. Analysis of the interview data highlighted the role of digital platforms in spreading misinformation, the susceptibility of newer businesses and younger taxpayers, and the erosion of trust and tax morale as critical factors affecting compliance behaviour. The study underlines the broader implications of misinformation on the tax system's integrity and the fiscal relationship between taxpayers and authorities, calling for strategies to enhance information dissemination and taxpayer education to bolster compliance and trust.
EFFECT OF TEACHERS’ REMUNERATION ON TEACHERS’ EFFICIENCY IN PRIVATE SECONDARY SCHOOLS IN NANSANA MUNICIPALITY, WAKISO DISTRICT.
Authors: Nassolo Saidat Wamala , Wakhungu Nathan
Published: April 2024

Background
The study aimed to establish the effect of teachers’ remuneration on teachers’ efficiency in private secondary schools in Nansana municipality, Wakiso District.
Methodology
A cross-sectional survey research design was utilized. The study involved 108 respondents namely 9 Directors, 9 head teachers, and 90 teachers randomly selected from 9 Schools. Data was collected using a self-administered questionnaire, interview guide, and documentary analysis. Data collected was compiled, sorted, and organized in frequencies and percentages. 
Results
The results were subjected to an x2 test at a 0.05% confidence interval and 6 degrees of freedom with a critical x² value at 12.59. The chi-square values obtained from the head teachers, teachers, and directors were 18.15, 14.94, and 37.51 respectively. The null hypothesis was rejected because the observed x2 values obtained were above the critical x² value at 12.59.    Therefore the study findings indicated that the reward system affects teachers’ motivation. 
Conclusion
It was then concluded that teachers’ motivation was subject to the existing reward system. Teacher’s remuneration is majorly determined by the interests of proprietors than based on the teachers’ ability, experience, and performance. This explains why teachers in private schools do not receive the same payments. Some private schools have better pay for their teachers and as such stand to maintain their teachers longer. Some teachers are better remunerated than others. Those who are favored have a higher motivation than those who are not.
Recommendation
Private secondary schools should improve their reward systems and the Ministry of Education should intervene to determine the minimum monthly pay to teachers so that teachers are properly rewarded on the existing cost of living, work performance, experience, and education levels.

The Relationship between Concept Perception and Student Achievement in the Subject Area of Chemistry in Science
Authors: Sumedha Ven B.Siri
Published: April 2024

Science education has undergone many reforms since the past to improve the learning and teaching process. Teachers' knowledge and motivation, and teachers' teaching techniques, determine how students understand science concepts. In the journey of taking students to innovations in education, the teacher who provides science education in the classroom has a great responsibility (Research and Development Branch, 2017). It is also necessary to identify the problems faced by students in building science education. The analysis of the examination department's results and evaluation reports shows that compared to other subjects, the minimum mark is obtained for the science subject. The Sri Lanka Examination Department's 2017 G.E.C. (G.E.) evaluation report also shows that among the three fields of science, biology, chemistry, and physics, the facility for the field of chemistry is low. For this reason, it was the main interest of this research to find out the correlation between student performance and conceptual understanding of students who learn the content of the chemistry subject of the science subject. For that purpose, the size of the sample was determined using the table of determination of the sample size presented by Krejcie & Morgan (1970) and the correlational study research strategy using 400 students of 08 secondary schools in the Kegalle district of Sri Lanka selected through a cluster random sampling method as the sample. The research was conducted using a quantitative design. For this, Katerina Salta & Chryssa Tzougraki (2004) used an aptitude test set according to the Liket scale and a structured type of achievement test set according to Bloom's classification to find out the level of concept perception of 11th grade students in a school in Greece. A control test was administered to 10% of the research instrument sample. By analyzing the data collected, the research instruments were standardized. Then by giving the research equipment to the main sample, the collected data was analyzed, and conclusions were drawn from the data interpretation. Here, a positive correlation of Pearson correlation coefficient (r= + 0.720) was found between students' conceptual understanding and student achievement. It was recognized that appropriate student-centered methods should be used in the learning and teaching process as student achievement increases when students' conceptual understanding increases.
Deception and Racism in the Tuskegee Syphilis Study
Authors: Jeon Yeji
Published: April 2024

During the twentieth century (1932-1972), white physicians representing the United States government conducted a human experiment known as the Tuskegee Syphilis Study on black syphilis patients in Macon County, Alabama. The creators of the study, who supported the idea of black inferiority and the concept that black people’s bodies functioned differently from white people’s, observed the effects of a disease called syphilis on untreated black patients in order to collect data for further research on syphilis. Black individuals involved with the study believed that they were receiving treatment, although in truth, treatments for syphilis were purposely held back from them. Not only this, but fluids from their bodies, such as blood and spinal fluid, were extracted to serve as research material without their awareness of the purpose of the collection. The physicians justified their approach by positioning it as mere observation, asserting that they were not actively intervening with the patients participating in the experiment. However, despite their claims of passivity, these white physicians engaged in various morally improper actions, including deceit, which ultimately resulted in the deaths of numerous black patients who might have had a chance at survival.
Mimicking microbone tissue by 3-dimensional printing
Authors: Lee Seung Yeon , Lee Jin Woo
Published: April 2024

Bones are mineralized connective tissues composed of osteoclasts, osteoblasts, and osteocytes. While bone is one of the few tissues that can regenerate in adulthood, its regeneration is limited in the case of large bone defects due to an environment that is detrimental to bone formation, which can be caused by soft tissue injury and impeded vascularization, ultimately reducing the potential for significant bone creation. Consequently, recent research has focused on tissue engineering and regenerative medicine to address these complex issues. This article reviews recent major advances in the cell components used for bone regeneration studies, specific markers of bone differentiation, 3-dimensional (3D) printing techniques for the structural mimicry of bones, and the use of natural and synthetic biomaterials. Functional bone structures and bone organoids can be created using 3D printing, which allows the reconstruction of bone tissue by attaching living cells to scaffolds. These scaffolds are designed with appropriate shapes and mechanical properties to mimic the bone microenvironment. The application of 3D printing in the development of bone organoids holds promise for providing improved solutions for the development of test systems for disease modeling and drug development.
Desempeño de dos índices normalizados de agua para la identificación de anegamientos en la cuenca del río Salado en Argentina
Authors: Salese Sofía , Lara Bruno
Published: April 2024

Introducción: Los anegamientos son fenómenos frecuentes en ecosistemas llanos con deficiencias en el drenaje fluvial que afectan la economía local y regional. Estos pueden ser identificados y analizados mediante teledetección.
Objetivo: Evaluar el desempeño de dos índices normalizados de agua, en épocas de precipitación anual máxima y mínima, para la identificación de anegamientos en la cuenca del río Salado, Argentina.
Materiales y métodos: Los años con precipitación anual máxima y mínima en el periodo 2001-2020 se obtuvieron de estimaciones satelitales de precipitación mensual provistas por la NASA a través de Google Earth Engine. Los anegamientos se identificaron con imágenes Landsat, a través de la aplicación de dos índices normalizados de agua (NDWI, por sus siglas en inglés -Normalized Difference Water Index- y NDWI modificado) con la finalidad de evaluar su desempeño en la obtención de imágenes binarizadas que representen mejor la realidad del área de estudio.
Resultados y discusión: Ambos índices tuvieron buena capacidad para la identificación de los cursos y cuerpos de agua permanente o semipermanente; sin embargo, solo el NDWI demostró mayor capacidad para la identificación de áreas anegadas con escasa profundidad (5 a 15 cm). El empleo de la banda del infrarrojo medio de Landsat (1 566 - 1 651 μm) es menos sensible a la carga de sedimentos del agua y es capaz de reflejar diferencias sutiles en ella, lo que proporciona una mayor capacidad para delinear el límite agua-suelo.
Conclusión: El empleo del NDWI demostró un comportamiento adecuado para la identificación de zonas anegadas en ecosistemas de muy baja pendiente.
Ekologisista kriiseistä globaalisti oikeudenmukaiseen kestävyyssiirtymään?
Authors: Bhatia Riina , Lamberg Emma
Published: April 2024

Sukupuoli ja sosiaalinen uusintaminen sekä globaalin talouteen kytkeytyvät koloniaalit valtasuhteet ovat olleet keskeisiä katvealueita niin kansainvälisessä kuin suomalaisessakin poliittisen talouden tutkimuksessa. Myös ekologisia kriisejä ja kestävyyssiirtymää koskevassa poliittisen talouden tutkimuksessa globaali sukupuolittunut eriarvoisuus on jäänyt suhteellisen vähälle huomiolle. Toisinaan myös ekologisten kriisien feministiset ja postkolonialistiset analyysit ovat jääneet etäälle toisistaan. Siksi tämä katsaus pohtii ekologisiin kriiseihin ja kestävyyssiirtymään liittyviä poliittisen talouden kysymyksiä korostamalla teoreettista synergiaa feministisen ja postkolonialistisen analyysin välillä. Ensin katsaus arvioi, miten feministinen ja postkolonialistinen tarkastelu lisää ymmärrystä ilmastokriisiin liittyvistä globaaleista rakenteellisista eriarvoisuuksista. Toiseksi katsaus luotaa, miten myös kestävyyssiirtymään tähtäävät toimet kietoutuvat globaalissa taloudessa koloniaaliin ja sukupuolittuneeseen alistukseen. Lopuksi katsaus perustelee, miksi feministinen ja postkolonialistinen tarkastelu ovat edellytyksiä globaalisti solidaarisemman kestävyyssiirtymän kuvittelulle, ja näin peräänkuuluttaa tarvetta talouteen kytkeytyvien kriisien moninäkökulmaiselle tarkastelulle.
North Atlantic Subtropical Mode Water properties: Intrinsic and atmospherically-forced interannual variability
Authors: Narinc Olivier , Penduff Thierry , Maze Guillaume , Leroux Stéphanie , Molines Jean-Marc
Published: April 2024

Abstract. This study investigates the contributions of the ocean’s chaotic intrinsic variability (CIV) and atmospherically-forced variability on the interannual fluctuations of the North Atlantic Eighteen Degree Water (EDW) properties. Utilizing a 1/4° regional 50-member ocean/sea-ice ensemble simulation driven by an original surface forcing method and perturbed initially, the forced variability of EDW properties is estimated from ensemble mean fluctuations, while CIV is determined from deviations around the ensemble mean within each member. The model successfully captures the main features of EDW, showing good agreement with observation-based ARMOR3D data in terms of location, seasonality, mean temperature and volume, and interannual variance of its main properties. CIV significantly impacts EDW, explaining 10–13 and 28–44 % of the interannual variance of its geometric and thermohaline mean properties, respectively, with a maximum imprint on EDW temperature. Observed and simulated intrinsic-to-total variance ratios are mostly consistent, dispelling concerns about a signal-to-noise paradox. This study also illustrates the advantages of ensemble simulations over single simulations in understanding oceanic fluctuations and attributing them to external drivers, while also cautioning against overreliance on individual simulations assessments.
The long-term impact of transgressing planetary boundaries on biophysical atmosphere–land interactions

Published: April 2024

Abstract. Human activities have had a significant impact on Earth's systems and processes, leading to a transition of Earth's state from the relatively stable Holocene epoch to the Anthropocene. The planetary boundary framework characterizes major risks of destabilization, particularly in the core dimensions of climate and biosphere change. Land system change, including deforestation and urbanization, alters ecosystems and impacts the water and energy cycle between the land surface and atmosphere, while climate change can disrupt the balance of ecosystems and impact vegetation composition and soil carbon pools. These drivers also interact with each other, further exacerbating their impacts. Earth system models have been used recently to illustrate the risks and interacting effects of transgressing selected planetary boundaries, but a detailed analysis is still missing. Here, we study the impacts of long-term transgressions of the climate and land system change boundaries on the Earth system using an Earth system model with an incorporated detailed dynamic vegetation model. In our centennial-scale simulation analysis, we find that transgressing the land system change boundary results in increases in global temperatures and aridity. Furthermore, this transgression is associated with a substantial loss of vegetation carbon, exceeding 200 Pg C, in contrast to conditions considered safe. Concurrently, the influence of climate change becomes evident as temperatures surge by 2.7–3.1 °C depending on the region. Notably, carbon dynamics are most profoundly affected within the large carbon reservoirs of the boreal permafrost areas, where carbon emissions peak at 150 Pg C. While a restoration scenario to reduce human pressure to meet the planetary boundaries of climate change and land system change proves beneficial for carbon pools and global mean temperature, a transgression of these boundaries could lead to profoundly negative effects on the Earth system and the terrestrial biosphere. Our results suggest that respecting both boundaries is essential for safeguarding Holocene-like planetary conditions that characterize a resilient Earth system and are in accordance with the goals of the Paris Climate Agreement.
biospheremetrics v1.0.2: an R package to calculate two complementary terrestrial biosphere integrity indicators – human colonization of the biosphere (BioCol) and risk of ecosystem destabilization (EcoRisk)

Published: April 2024

Abstract. Ecosystems are under multiple stressors, and impacts can be measured with multiple variables. Humans have altered mass and energy flows of basically all ecosystems on Earth towards dangerous levels. However, integrating the data and synthesizing conclusions is becoming more and more complicated. Here we present an automated and easy-to-apply R package to assess terrestrial biosphere integrity that combines two complementary metrics. (i) The BioCol metric that quantifies the human colonization pressure exerted on the biosphere through alteration and extraction (appropriation) of net primary productivity.(ii) The EcoRisk metric that quantifies biogeochemical and vegetation structural changes as a proxy for the risk of ecosystem destabilization. Applied to simulations with the dynamic global vegetation model LPJmL5 for 1500–2016, we find that large regions presently (period 2007–2016) show modification and extraction of >20 % of the preindustrial potential net primary production. The modification (degradation) of net primary production (NPP) as a result of land use change and extraction in terms of biomass removal (e.g., from harvest) leads to drastic alterations in key ecosystem properties, which suggests a high risk of ecosystem destabilization. As a consequence of these dynamics, EcoRisk shows particularly high values in regions with intense land use and deforestation and in regions prone to impacts of climate change, such as the Arctic and boreal zone. The metrics presented here enable spatially explicit global-scale evaluation of historical and future states of the biosphere and are designed for use by the wider scientific community, being applicable not only to assessing biosphere integrity but also to benchmarking model performance. The package will be maintained on GitHub and through that we encourage its future application to other models and data sets.
The Implementation of Coordinated Access to End Homelessness in Ontario, Canada
Authors: Nichols Naomi , Martin Mary Anne
Published: April 2024

To receive federal homelessness funding, cities in Canada must adhere to federal policy directives associated with the government of Canada’s Reaching Home program. These directives include the implementation of a homelessness management information system (HMIS) and a Coordinated Access process. In this article, we draw on 90 in-depth interviews and extensive policy and institutional analysis to assess the implementation of Coordinated Access in one Ontario city. Our findings suggest that none of the four pillars of Coordinated Access (access, assessment, prioritization, matching, and referral) work as intended. Structural and systemic challenges (e.g., related to housing stock, staff turnover, inaccessibility of shelters, criminalizing municipal bylaws, and the reliability of the assessment tool) undermine the efficacy of the process as a means of improving transparency, service coordination, and housing outcomes. Despite being an early adopter of the Coordinated Access process, this Ontario municipality continues to struggle with a growing housing affordability crisis and an unhoused population.
Examining Coping Skills, Anxiety, and Depression Dynamics Amidst the COVID-19 Pandemic
Authors: Moment Lauren
Published: April 2024

This cross-sectional study, conducted amid the COVID-19 pandemic, delves into the intricate connections between coping strategies and levels of anxiety and depression, presenting vital implications for medical, clinical, and broader societal contexts. As crises like the pandemic highlight the importance of adaptive coping, this investigation underscores the imperative to comprehend and address maladaptive coping strategies. The study utilized a diverse sample of 386 participants during the pandemic's peak, employing online platforms for recruitment and ensuring broad demographic representation. Data were collected through self-report measures, including the Patient Health Questionnaire-4 (PHQ-4) for depression and anxiety symptoms and the Brief Coping Orientation to Problems Experienced (COPE) inventory to assess coping skills across various domains. The coping skills assessment measured strategies such as Self-Distraction, Active Coping, Denial, Substance Use, Emotional and Instrumental Support, Behavioral Disengagement, Venting, Positive Reframing, Planning, Humor, Acceptance, Religion, and Self-Blame. The Colorado Multiple Institutional Review Board prioritized and approved ethical considerations, and participants provided informed consent. Data analysis involved rigorous cleaning, recoding, and quantitative analysis using SPSS. Descriptive statistics, regression analyses, and correlation analyses were employed to uncover nuanced relationships between coping strategies and mental health outcomes, contributing to understanding the phenomena under investigation within the context of the pandemic. The findings highlight the pivotal role of individualized approaches and the potential of humor as an essential coping mechanism, emphasizing the need for tailored interventions during crises.

Published: April 2024

Stunting, a persistent nutritional issue arising from prolonged inadequate nutrient intake, poses substantial risks such as heightened morbidity, mortality, and compromised cognitive, psychomotor, and verbal development. In Indonesia, addressing stunting in children under two necessitates urgent community empowerment, given its multifaceted nature. The aim of this study was to assess the effects of an intervention targeting mothers of toddlers, called RT kawal baduta (ERKADUTA) model, a local community-based assistance for babies under two years old. A quasi-experiment using pre-test and post-test with a control group design was conducted. Employing a quantitative analytic approach with 112 respondents, the effectiveness of ERKADUTA model to improve the knowledge, attitude, and practice of stunting prevention among mothers with child under two years old was assessed. ERKADUTA program was run for three months. The Wilcoxon test was used to determine score changes before and after program in both groups, while the Mann-Whitney test was used to analyze the score differences of knowledge, attitude and practice between intervention and control groups. Our data indicated that there were changes in knowledge, attitudes, and practices in preventing stunting in both the intervention and control groups. There are significant differences in knowledge (p<0.001, effect size=-0.855), attitude (p<0.001, effect size=-0.864), and practice score (p<0.001, effect size=-0.924) between the intervention and control groups after the intervention. This study highlights that the ERKADUTA model emerged as a potent catalyst in improving stunting prevention behaviors among mothers with toddlers and this model holds promise for addressing the complexities of stunting in Indonesia.

Published: April 2024

It is widely acknowledged that smoking exacerbates the severity of infectious diseases. A presumed mechanism involves the damage inflicted by tobacco smoke on the organs of host organisms. In this study, an alternative hypothesis was explored: smoking enhances the virulence of bacteria. This possibility was investigated using Escherichia coli as the bacterial agent and Drosophila as the host organism. Our inquiry focused on the potential gene expression changes in E. coli subsequent to exposure to tobacco smoke. Analysis of the transcription promoter activity of genes encoding proteins within the E. coli two-component system, a regulatory machinery governing gene expression, revealed the activation of twelve out of 50 promoters in response to tobacco smoke. Subsequently, Drosophila was infected with E. coli exposed to tobacco smoke or left untreated. Interestingly, there were no significant differences observed in the survival periods of Drosophila following infection with E. coli, whether treated or untreated with tobacco smoke. Contrary to the initial hypothesis, the findings suggest that while tobacco smoke alters gene expression in E. coli, these changes do not appear to impact bacterial virulence. Although this study has illuminated the influence of tobacco smoke on the gene expression of E. coli, further analyses are necessary to elucidate the implications of these changes. Nevertheless, the results imply that smoking affects not only host organisms but may also exert influence on invading bacteria.

The heat exchanger is used in many industrial and engineering activities.Where, numerous applications confirms on a large heat transfer rate. However, the twisted tube is one of heat transfer rate enhancement methods. Also, the turbulent flows are often used instead of laminar for enhancement heat transfer rate. Therefore, the tube arrangement can be used in a suitable way for utilized this purpose. The shape features of tubes in the heat exchangers are very important for enhancing their performance. As well, the pressure drop and heat transfer rate have a remarkable effect on the thermal efficiency of the heat exchanger. In this research, a numerical investigation with a new way for heat exchanger tube staggered arrangement is presented. Where new solid spiral rods with oval sections are inserted in front of main tubes to induce high turbulent flow intensity as well as redistribution airflow over exchanger tubes. However, the new air distribution will help the airflow pressure over all the tubes to push the thermal boundary symmetrically behind the tubes. Therefore, two different sectional tubes were presented (circular and elliptical). These cross-sectional areas for both types have the same values. The main tubes have no twisted to prevent decreases in pressure. The numerical analysis used the K- ε model at a low Reynolds number to the simulation of this situation. Where, the eddy will generate in the vicinity region to pipe walls due to twisted pipe as well as the obstruction the cross flow. However, there are a good improvement of heat transfer rate without spend any energy depending on the control the shape and arrangement of pipes. The results show that the corrugated rod will increase the Nusselt number at different values of Reynolds. However, the elliptic tube gives the best results for heat transfer rate and maximum Nusselt number. The results compared with others works and give a good agreement.

Amaç: Dünyada ve Türkiye'de en sık görülen kanser türlerinden biri olan meme kanseri, kanser nedenli ölüm oranları arasında ilk sıralarda yer almaktadır. Bu nedenle bu hastalığın tedavisine yönelik yeni araştırmalar yapılmaktadır. Biz de güçlü bir antioksidan olan melatoninin kanserle ilişkisini ve kanser hastalığının çözümüne katkısını araştırmayı amaçladık.
Yöntemler: Çalışmamızda melatoninin sitotoksik dozlarını ve IC50 değerini belirleyebilmek için MCF-7 hücre hattına 10 nM–100.000 nM aralığında melatonin konsantrasyonları uygulandı. Melatonin uygulamasının ardından MTT analizi ile hücre canlılığı tespiti yapıldı ve melatonin için etkin dozlar belirlendi. MCF-7 hücreleri, 5 konsantrasyon (10, 100, 1000, 10.000 ve 100.000 nM) melatonin dozu ile 24 saat inkübasyon işlemine tabi tutuldu. Tüm gruplarda melatonin sitotoksisitesi, TAS, TOS, apoptotik aktivite (Bax ve p53 immünpozitifliği) ve p53 geninin ekspresyon düzeyleri incelendi.
Bulgular: 24 saatlik inkübasyon sonunda MCF-7 hücrelerine uygulanan melatoninin hücre proliferasyonunu inhibe ederek sitotoksik etki yaptığı, p53 gen ekspresyonunu ve Bax protein sentezini artırdığı tespit edildi. İmmünsitokimyasal boyamada Bax ve p53 immünpozitifliğinin arttığı belirlendi. Ayrıca melatonin tedavisi TAS'ı artırıp TOS'u azalttı.
Sonuç: Bu etkiler, melatoninin p53 gen ekspresyonu ve Bax proteinindeki artışa bağlı olarak apoptoz aktivasyonunu indüklediğini ve dolayısıyla kanser tedavisinde kullanılabilecek yardımcı bir ajan olabileceğini göstermektedir.

Home Advantage and Away Disadvantage of Turkish Football Teams in European Competitions
Authors: Kuvvetli Umit
Published: April 2024

Home advantage (HA) is used as a concept that means teams win more matches and score more goals than their opponents on their home field. Similarly, away disadvantage (AD) can be explained as teams scoring fewer points and scoring fewer goals away than their opponents. In this study, the matches played by 5 Turkish teams, played at least 30 matches in European competitions, between the 1991/1992 and 2022/2023 seasons, a total of 784 matches were analyzed and team-specific HA and AD values were estimated using Generalized Estimation Models. According to the results, all 5 Turkish teams have a significant HA in European competitions, but all teams also experience an AD and there is no difference among the teams in terms of both HA and AD. Furthermore, Belgian teams were found to be the teams where Turkish teams experienced the most home advantage and did not experience an away disadvantage. On the other hand, the teams with the lowest HA value and the highest AD value of Turkish teams were found to be Ukrainian teams. The results of the study show that playing in Türkiye is difficult for all European teams and that the AD of Turkish teams in countries with higher fan support is lower than in other countries.
