Value-based optimization model for cultural route design: Ancient Water Supply Heritage of Istanbul (Türkiye)

Cultural tourism has become an increasingly growing human activity in today's world. Therefore, various cultural/natural heritage areas or buildings face large tourist crowds, causing physical, social, or cultural deterioration. Cultural routes, which provide a systematic approach and planned tourists move, can reduce the negative effects of overtourism. This study aims to develop an optimization model as a supportive tool for the cultural route design process. The proposed optimization model aims to maximize cultural experience while satisfying constraints on heritage values, building types, historical eras, and general routing rules. Moreover, this model, creating optimized cultural routes, is expected to contribute to regulating economic income and tourist density. As a case study, the ancient water supply systems of Istanbul, inherited from the Roman and the Ottoman empires and currently overlooked, are investigated. Heritage values, mentioned in the extensive literature, are reviewed and the values/attributes for this study are appointed according to the characteristics of the case heritage assets, and their environment. The values of the case structures are evaluated with value analysis after field study. An optimum cultural route for Istanbul's historical water supply heritage, according to the objective and the constraints of the model, is obtained by solving the model with the case data. The resulting route can make this overlooked heritage of Istanbul recognized and spread the tourist density in the city center. The model is flexible, allowing for easy modification of the objective function, constraints, and values when designing routes across various heritage sites. This model can be used not only in the design of new cultural routes but also in optimizing existing routes.

Application of waste eggshells elevates phytoremediation efficiency of Pb-Zn mine-contaminated farmland and mitigates soil greenhouse gas emissions: A field study

Remediating heavy metal (HM)-contaminated farmlands and sequestering soil carbon for emission reduction have been prominent topics in environmental research in recent years. However, few studies have looked into the soil greenhouse gas (GHG) impacts of growing hyperaccumulators in composite HM-contaminated farmland, as well as agronomic measures to remediate soil HMs while mitigating GHG emissions. To investigate fertilization measures to improve phytoremediation efficiency and mitigate GHG emissions, S. photeinocarpum was planted with three different fertilization measures on farmland contaminated by lead-zinc (Pb-Zn) mines (1200 kg ha−1 eggshell, 125 kg ha−1 28-homobrassinolide, and 16.7 kg ha−1 mineral potassium fulvic acid) during its growth period. The findings are as follows: Eggshell application significantly enhanced the translocation factor (TF) of Pb, Zn, and cadmium (Cd) from the roots to the shoots of Solanum photeinocarpum. Moreover, eggshells notably increased the bioaccumulation factor (BCF) of Cd and Pb in plant shoots by 120.75% and 159.09%, respectively. Regarding GHG emissions, the combined application of eggshells and 28-homobrassinolide substantially lowered the global warming potential (GWP) of the soil. Correlation analyses revealed that eggshell application increased the relative abundance of the Gemmatimonadota bacterial phylum in the soil, facilitating Pb and Cd migration from the roots to shoot tissues in S. photeinocarpum. Eggshell use inhibited nitrate nitrogen (NO3−-N) transformation into nitrous oxide (N2O) by the Myxococcota bacterial phylum and reduced N2O release from the soil. The application of low-cost eggshells can achieve a win-win situation of soil HM remediation and GHG emission reduction, as well as provide simple and scalable management measures for HM-contaminated farmland.

Recombinant Antibody Fragments for Neurological Disorders: An Update.

Recombinant antibody fragments are promising alternatives to full-length immunoglobulins, creating big opportunities for the pharmaceutical industry. Nowadays, antibody fragments such as antigen-binding fragments (Fab), single-chain fragment variable (scFv), single-domain antibodies (sdAbs), and bispecific antibodies (bsAbs) are being evaluated as diagnostics or therapeutics in preclinical models and in clinical trials. Immunotherapy approaches, including passive transfer of protective antibodies, have shown therapeutic efficacy in several animal models of Alzheimer's disease (AD), Parkinson's disease (PD), frontotemporal dementia (FTD), Huntington's disease (HD), transmissible spongiform encephalopathies (TSEs) and multiple sclerosis (MS). There are various antibodies approved by the Food and Drug Administration (FDA) for treating multiple sclerosis and two amyloid beta-specific humanized antibodies, Aducanumab and Lecanemab, for AD. Our previous review summarized data on recombinant antibodies evaluated in pre-clinical models for immunotherapy of neurodegenerative diseases. Here, we explore recent studies in this fascinating research field, give an update on new preventive and therapeutic applications of recombinant antibody fragments for neurological disorders and discuss the potential of antibody fragments for developing novel approaches for crossing the blood-brain barrier (BBB) and targeting cells and molecules of interest in the brain.

Efficacy of a chewable tablet containing sarolaner, moxidectin and pyrantel for the treatment of generalised demodicosis in dogs.

Demodicosis is common in dogs and is caused by proliferation of commensal Demodex canis mites. To evaluate the efficacy of sarolaner in combination with moxidectin and pyrantel (SMP) for the treatment of generalised demodicosis in dogs. One hundred and thirty dogs with generalised demodicosis. In two separate randomised masked studies (laboratory and field studies), dogs received monthly oral SMP or afoxolaner + milbemycin oxime (AM). In the laboratory study, dogs received three monthly treatments with biweekly mite counts and clinical evaluations. In the field study, mite counts and clinical evaluations were performed monthly and treatments were administered until two consecutive skin scrapings were negative. Both products were tolerated well. In the laboratory study, mite counts for SMP were significantly (p < 0.001) reduced by 88.8% on Day (D)14, by 99.2% on D29, and no live mites were detected thereafter with no statistically significant difference (p = 0.96) between the two treatment groups. In the field study, SMP provided 92.4%, 98.1%, 100% and 100% reduction in arithmetic mean live mite counts on D30, D60, D90 and D120, and was non-inferior to the control product on D30 and D60. Clinical signs of demodicosis improved in all dogs. Monthly administration of SMP was effective for the treatment of generalised demodicosis in dogs as it eliminated Demodex mites after two monthly treatments in the laboratory study, and at most after three monthly treatments in the field study.

Critical Success Factors and Acceptance of the Casemix System Implementation Within the Total Hospital Information System: Exploratory Factor Analysis of a Pilot Study.

The health care landscape is evolving rapidly due to rising costs, an aging population, and the increasing prevalence of diseases. To address these challenges, the Ministry of Health of Malaysia implemented transformation strategies such as the Casemix system and hospital information system to enhance health care quality, resource allocation, and cost-effectiveness. However, successful implementation relies not just on the technology itself but on the acceptance and engagement of the users involved. This study aims to develop and refine items of a quantitative instrument measuring the critical success factors influencing acceptance of Casemix system implementation within the Ministry of Health's Total Hospital Information System (THIS). A cross-sectional pilot study collected data from medical doctors at a hospital equipped with the THIS in the federal territory of Putrajaya, Malaysia. This pilot study's minimum sample size was 125, achieved through proportionate stratified random sampling. Data were collected using a web-based questionnaire adapted from the human, organization, and technology-fit evaluation framework and the technology acceptance model. The pilot data were analyzed using exploratory factor analysis (EFA), and the Cronbach α assessed internal reliability. Both analyses were conducted in SPSS (version 25.0; IBM Corp). This study obtained 106 valid responses, equivalent to an 84.8% (106/125) response rate. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.859, and the Bartlett test of sphericity yielded statistically significant results (P<.001). Principal component analysis identified 9 components explaining 84.07% of the total variance, surpassing the minimum requirement of 60%. In total, 9 unique slopes indicated the identification of 9 components through EFA. While no new components emerged from the other 7 constructs, only the organizational factors construct was divided into 2 components, later named organizational structure and organizational environment. In total, 98% (41/42) of the items had factor loadings of >0.6, leading to the removal of 1 item for the final instrument for the field study. EFA ultimately identified 8 main constructs influencing Casemix implementation within the THIS: system quality, information quality, service quality, organizational characteristics, perceived ease of use, perceived usefulness, intention to use, and acceptance. Internal reliability measured using the Cronbach α ranged from 0.914 to 0.969, demonstrating high reliability. This study provides insights into the complexities of EFA and the distinct dimensions underlying the constructs that influence Casemix system acceptance in the THIS. While the findings align with extensive technology acceptance literature, the results accentuate the necessity for further research to develop a consensus regarding the most critical factors for successful Casemix adoption. The developed instrument is a substantial step toward better understanding the multidimensional challenges of health care system transformations in Malaysia, postulating an underpinning for future fieldwork and broader application across other hospitals.

Public Perception of the Higher Education System under the Regime of the Islamic Emirate of Afghanistan

A modern, free, and dynamic higher education system is the basic and critical element of successful nation, and it can contribute to the progress and development of a country. Under both regimes of the Islamic Emirates of Afghanistan, the higher education system has undergone significant changes to align with the government’s interpretation of Islamic principles. This study is important to understand how Afghan society views the changes and policies implemented in the education sector under the current regime. The research study aims to evaluate public sentiment regarding access, quality, and inclusivity of higher education, particularly in relation to gender, curriculum changes, and ideological shifts. This paper focuses on the Taliban’s higher education system and investigates public responses to educational policies. This paper will offer recommendations to all stakeholders involved in the Afghan higher education system, aimed at improving its management and development during this crucial period. This work employs non-doctrinal and library research methodology. Non-doctrinal research examines how laws are applied and experienced in practice by collecting data through surveys, interviews, field studies, and observations. In this research study, data was collected through a questionnaire and then analyzed through SPSS. Moreover, in the library research methodology, most of the reputable and trustworthy academic sources such as textbooks, scholarly published and unpublished journal articles, law reports, and online websites related to the research area were analyzed through descriptive, explanatory, and analytical research approaches. The Afghan higher education system, established in the 1930s, has faced continuous political pressures, especially during periods of conflict like the Soviet invasion and civil war from the 1980s to 1990s. Women face major limitations in higher education, including restrictions on fields of study and exclusion from faculty positions, raising concerns about gender equality and access to education.

Effect of sowing methods, spacings, and fertilizer levels on quantitative and qualitative traits and economics of brown top millet (Brachiaria ramosa L.) under different cropping seasons

A field study was conducted during the Summer, Kharif, and Rabi seasons of 2023-2024 to evaluate brown top millet under two sowing methods (direct sowing and transplantation), three spacing configurations (20 x 10, 30 x 10 and 45 x 10 cm), and three fertilizer doses (75% of the recommended dose of fertilizer (RDF) (45:20:15 kg ha-1), 100% RDF (60:30:20 kg ha-1), and 125% RDF (75:40:25 kg ha-1)). The study was designed as a factorial randomized complete block design assessing growth, yield, thiamine content, and economics. The results indicated that the summer season was more favorable for growth than the Kharif and Rabi seasons. Direct sown crops (E1) exhibited significantly higher growth attributes, yield, and economics than transplanted crops (E2). The spacing configuration of 45 x 10 cm (S3) recorded significantly superior growth and yield parameters compared to 20 x 10 cm (S1). Applying 125% RDF (N3) resulted in significantly enhanced growth, yield, quality, and economic return compared to 75% RDF. Among the interactions, the combination of direct sown with narrow spacing and 125% RDF (E1 x S1 x N3) led to significantly higher growth parameters. In comparison, the combination of direct sowing with wider spacing and 125% RDF (E1 x S3 x N3) resulted in higher grain yields (2005, 1759, 1548 kg ha-1) and benefit-cost ratios (2.64, 2.58, and 2.58) across the same seasons. However, the differences in grain yield among the treatment combinations were statistically non-significant. These findings provide a valuable foundation for future research and agricultural practices aimed at maximizing the potential of brown top millet.

Residue dissipation and dietary risk of cyprodinil and fludioxonil residues in green onions: ensuring safe consumption in Egypt

ABSTRACT As a vegetable commodity, onions are of considerable economic significance. They are a significant source of foreign exchange revenues in the fruit and vegetables sector, in addition to being essential for domestic consumption. However, green onions are frequently treated with multiple fungicides. As a result, there is currently a significant focus on the potential health hazards of consuming green onions, due to dietary risks and the presence of various fungicide residues. The pre-mixture fungicide cyprodinil and fludioxonil are widely used to control fungal disease in green onions. To assure consumer safety, residues in the final product must be investigated. Following Good Agricultural Practices (GAPs), field studies were carried out to investigate cyprodinil and fludioxonil dissipation and terminal residues on green onions. The concentrations of cyprodinil and fludioxonil in green onions decreased with time by a first-order kinetic model, with considerable degradation of 95.6% and 83.5%, respectively, after 14 days of single treatment at the recommended rate. According to the terminal results, it is advisable to wait for 7 days after applying the recommended dose of Switch fungicide before harvesting. The findings indicated that the presence of cyprodinil and fludioxonil residues in green onions did not pose a significant dietary risk for consumers. This study is intended to ensure the safe and proper use of cyprodinil and fludioxonil in green onions in Egypt.

Farmers profit from selling perfectly ripe wet coffee beans 42-43%, wet mixed coffee beans (8%), and dry mixed coffee beans 63-71%. A traceability system named Kinton was successfully developed and integrated with the Firebase database to store all information.

The role of perspective-taking in attenuating self-group distancing in women managers.

Contrary to expectations about solidarity and sisterhood between women, women managers sometimes distance themselves from junior women in the workplace when facing identity threat, that is, the feeling that one's social identity-such as race or gender-is devalued or undermined. For example, women managers might distance themselves from lower status junior women by seeing themselves as more masculine and career committed than their junior women colleagues. To advance our understanding of how to combat self-group distancing, the present research proposed and tested whether taking the perspective of junior women would attenuate these ingroup-distancing tendencies in women managers. Findings from a field study and an experimental study indicated that women managers reported greater self-distancing from junior women (on masculine trait perceptions) compared to women employees. As predicted, this effect was attenuated for women managers with high levels of perspective-taking (Study 1) and for women who were experimentally led to take the perspective of junior women (Study 2). For ratings of career commitment and support for affirmative actions, we did not replicate the self-ingroup distancing effect reported in the literature. Theoretical and practical implications of these findings are discussed.
