A field experiment was carried out with sorghum (CO 26) in an Alfiso! having hard pan at shallow depth to study the interaction effect of tillage practices, organics and nitrogen on grain yield and root volume of sorghum. Remarkable influence of chiseling on the root length and root volume of the sorghum crop was evidenced from the better proliferation of roots in to the deeper layers. Root length increased with increasing levels of N, while organics had no effect on root length. Chiseling significantly increased the grain yield of sorghum. Among the organics, the composted coir pith registered the highest grain yield of sorghum. The grain yield of sorghum due to chiseling and 75 per cent of the recommended N was on par with the mould board or country ploughing with 100 per cent recommended N indicating the scope of saving 25 per cent fertiliser N.

The physical and thermal properties of three varieties of turmeric rhizomes viz. BSR I, BSR II and Erode local were studied. BSR I had the highest primary finger length (82 mm) over the other varieties. The Erode variety showed higher weight for 1000 rhizomes. The bulk density, true density, moisture content, coefficient of friction, specific heat and thermal conductivity increased with increase in moisture content, for all the three varieties tested. Multiple regression equations were developed to predict all the physical and thermal properties of turmeric rhizomes as a function of moisture content.

Published: June 2023

A cranioplastia para os tratamentos de defeitos ósseos cranianos tem como o seu principal objetivo a reconstrução tridimensional e funcional da calota craniana. As cirurgias assistidas por computador (CAS) vem sendo utilizadas desde os anos 90 de forma eficiente e trazendo melhorias e otimização nas abordagens cirúrgicas craniofaciais reconstrutivas, principalmente em grandes defeitos ósseos. Este relato de caso clínico aborda o planejamento virtual e de tecnologia CAD/CAM na reconstrução craniofacial secundária com a utilização de polimetilmetacrilato (PMMA). Paciente de sexo masculino, 48 anos, apresentava dois defeitos ósseos em região frontal com deiscência da pele para dentro do seio frontal. Foi realizada uma tomografia computadorizada com cortes de 1mm e convertidos em um modelo 3D do osso frontal e no molde do defeito ósseo em tamanho real. Para abordagem dos defeitos ósseos, houve a participação de um neurocirurgião para o tratamento em dura-máter, cranialização do seio frontal e obliteração do ducto naso-frontal, sendo finalizada pela equipe de cirurgia bucomaxilofacial. Após a cirurgia, foi realizado um exame tomográfico sendo observados uma perfeita adaptação entre a prótese e os contornos ósseos e um ótimo contorno anatômico do osso frontal, tornando-se satisfatório ao planejamento cirúrgico inicial. A utilização de um planejamento virtual e do sistema CAD/CAM resultou em uma maior previsibilidade e maior segurança ao procedimento de reconstrução craniofacial além de redução do tempo transoperatório. O material utilizado, o PMMA, apresentou-se como um material de fácil manipulação, baixo custo e com perfeita adaptação aos contornos ósseos.

Published: June 2023

Introduction: This study investigated the differences in ACTN3, ACE and ADRB3 variants in top-level soccer players who entered the Croatian National Team and the ones who did not but played for two best Croatian teams. Material and Methods: The buccal swabs were collected from 56 soccer players playing for the Croatian National Team (N = 31) and/or for one of the two most prestigious Croatian soccer clubs (N = 25). Each participant’s genotype was determined by analyzing the single-nucleotide polymorphism. The ACTN3 gene (rs1815739) on chromosome 11 and the ACE (rs1799752) gene on chromosome 17 were determined. Results: No significant differences between the players who entered the national team and the ones who did not were found in ACTN3 R577X (p = 0.437) and ADRB3 (p = 0.202) polymorphism distribution, while the differences existed in ACE (p = 0.044). The significant differences were determined in the “Athletic index” between the national-team and non-national-team players (p = 0.023). Regarding the position, the “Athletic index” was significantly higher only in national team midfielders (2.50 ±1.08 points vs. 1.38 ±1.06; p = 0.034). Conclusion: It seems that the soccer players with a favorable genetic combination on the ACTN3 gene and ACE gene might have had a better chance to enter the National Team.

Christianity without Christ?
Authors: Schoeps Julius H.
Published: June 2023

Ever since the publication of Dohm’s Ueber die bürgerliche Verbesserung der Juden (On the Civil Improvement of the Jews) in 1781, which argued for Jewish political equality on humanitarian grounds, more and more voices joined those demands. Prominent among them was David Friedländer, a friend and disciple of Moses Mendelssohn. One of the leading figures of the Berlin Haskalah, he worked towards establishing equal legal status for Jews in Prussia. Friedländer did not accept the given view of his times, the antithesis of Jew and German. For him only the antithesis Jew–Christian existed and even that he tried to reconcile by finding common ground in a religion of reason, the groundwork of which he laid out in an Open Letter in 1799. What he proposed at that time may have been illusionary, but it certainly met with approval in enlightened Jewish circles. Friedländer therefore not only stands for those who dared to break with the traditions, but also for the generation of those who consciously aimed at the denationalization of traditional Judaism – and thus decided in favour of the confessionalization and the Germanness of the Jews.

DEMOCRACY AND ECONOMIC GROWTH IN MIST COUNTRIES: AN EMPIRICAL ANALYSIS
Authors: BAYAR İlyas
Published: June 2023

Studies on institutions, which are one of the main determinants of economic growth, have been increasing intensively in recent years. In this context, despite many empirical and theoretical studies on the relationship between democracy and economic growth, there is no consensus about the effect of democracy on economic growth. This study analyzes the relationship between democracy and economic growth for MIST (Mexico, Indonesia, South Korea, and Turkey) countries. Firstly, the cross-sectional dependence was examined in the study for the 1973–2021 period. The second generation panel unit root test (Pesaran CADF (2007)) was chosen because of the cross-sectional dependence among the series. The stationarity of the variables at I(1) is ensured. Having determined the cointegration relationship (Westerlund Durbin-H test (2008)) between the series, the Panel CCE estimator was used to estimate the cointegration coefficients. Kónya causality test was used for the causality between democracy and economic growth. It is found that an increase in the level of democracy boosts the economic growth. It is suggested that the MIST nations continue to undertake policies targeted at establishing democratic institutions that contribute to economic progress.

Published: June 2023

The COVID-19 pandemic has a negative impact on many aspects of life. The global economic downturn is one of these negative consequences. Nonetheless, even though everyone feels the threat of this pandemic for themselves, some people still have the empathy to help others. An empirical analysis of this empathy attitude is expected to be a catalyst in realizing a social force for the community to work together to combat this pandemic. This study will look at how people felt about donating during the COVID-19 pandemic on Twitter. The goals of this study are to (1) compare differences in donor desire before and during the COVID-19 pandemic using the developed model, and (2) determine whether there is a significant difference in empathy for donating before and during the pandemic. This study employs computational social science (CSS) techniques to achieve this goal. The data was obtained from Twitter using the keyword "donation" in the 24 months preceding the pandemic and in the 24 months following the pandemic's arrival in Indonesia. Data analysis includes hypothesis testing using Mann-Whitney and Cohen's D statistical tests, showing a significant increase in online donation support among Indonesian Twitter users since the COVID-19 pandemic hit. From the results of data processing data obtained 159.995 data in accordance with the criteria to be analyzed. From the results of the Mann-Whitney test, all variables showed significant results between before and during the Covid-19 pandemic and in the results of the Cohen's d test, all variables got a large effect size. From the results of the two tests, it can open Twitter social media users who have increased empathy to donate during the Covid-19 pandemic in Indonesia

The study aimed to examine the influence of ChatGPT on the academic performance and learning perception of eleventh-grade students in a United Arab Emirates school in the field of electronic magnetism. The participants were randomly divided into two groups: an experimental group granted access to ChatGPT and a control group without access to ChatGPT. The research spanned four weeks, during which the experimental group was instructed to utilize ChatGPT whenever they required assistance with the course content. The study employed a mixed-methods design, collecting both quantitative and qualitative data to assess the impact of ChatGPT on student learning and perception. Quantitative data was gathered through pre-/post-test surveys, measuring participants’ course achievement and perception of learning with ChatGPT. Qualitative data was collected via open-ended survey questions, allowing participants to provide feedback and suggestions for improvement. The study revealed that ChatGPT had a positive influence on student achievement and perception of learning in the field of electronic magnetism. The experimental group displayed significant enhancements in their scores on the post-test measuring the impact of ChatGPT on student achievement, exhibiting higher mean scores across all subscales compared to the control group. Furthermore, both male and female participants acknowledged ChatGPT as a valuable learning tool, offering suggestions for enhancing its functionality. The study suggests that ChatGPT is an effective tool for enhancing student learning and achievement in specific academic domains. However, further research is needed to explore its generalizability to other contexts and disciplines, as well as to address potential challenges and limitations of ChatGPT use in education.

“On a Risky Slope of Democracy”: Racialized Logics Embedded in Community–School Board Interactions
Authors: Daramola Eupha Jeanne , Enoch-Stevens Taylor , Bridgeforth James C. , Nkansah-Amankra Akua
Published: June 2023

As school board meetings are integral sites of local education policymaking, scholars must consider how structural racism manifests in these spaces across various district contexts. We examine how racialized institutional logics undergird the interactions between majority-Black district leadership and a local Black community during school board meetings. Through an ethnographic case study of school board meetings over the 2019–2020 school year, we find that racialized pressures led predominantly Black school board members and district administrators to uphold policies and practices that limited two-way authentic interactions with their Black constituents. In conclusion, we argue that racial representation in educational politics may be important, but is not sufficient unless accompanied by changes to policies and practices that privilege Whiteness and reproduce racism.

Published: June 2023

The construction of embankment for roadway interchange system at urban area is restricted due to the large geometry requirements, since the value of land required for such construction is high, and the area available is limited as compared to rural area. One of the optimum solutions to such problem is the earth reinforcement technique which requires a limited area for embankment construction. Gypseous soil from Al-Anbar governorate area was obtained and subjected to various physical and chemical analysis to determine it is properties. A laboratory model box of 50x50x25 cm was used as a representative embankment; soil has been compacted in five layers at maximum dry density (modified compaction) and an aluminum reinforcement strips were introduced between layers. The model was subjected to cyclic loading and the vertical and lateral deformations were detected at different stages of loading cycles using LVDT. The reinforced soil embankment under soaking condition exhibited vertical settlement at the top surface was (12.55 mm) while the lateral displacements at (1st, 3rd layer) were (2.18, 1.32) mm respectively at (47 load cycles).For reinforced gypseous soil, embankment without soaking cured for 24 hours, the Number of load cycles was found to be (165) loading cycles with vertical displacement (9.12 mm), that means an improvement of 59%. Accordingly, the lateral displacement in 1st and 3rd layers were (3.28, 2.59) mm respectively which observes improvement by (28% and 5%) respectively. The rates of improvement are taken with respect to the reinforced pure dry soil sample.

Published: June 2023

Exposure of reinforced concrete buildings to an accidental fire may result in cracking and loss in the bearing capacity of their major components, columns, beams, and slabs. It is a challenge for structural engineers to develop efficient retrofitting techniques that enable RC slabs to restore their structural integrity, after being exposed to intense fires for a long period of time. Experimentalinvestigation was carried out on twenty one slab specimens made of self compacting concrete, eighteen of them are retrofitted with CFRP sheets after burning and loading till failure while three of them (which represent control specimens) are retrofitted with CFRP sheet after loading till failure without burning. All slabs had been tested in a simply supported span and subjected to two-point loading. The main variables were the effect of different temperature levels (300ºC, 500ºC and 700ºC),different concrete compressive strength (20MPa, 30MPa and 40MPa) and cooling rate (gradually and sudden cooling conditions) on the behavior of retrofitted one way slabs .The structural response of each slab specimen was investigated in terms of load-deflection behavior, ultimate load carryingcapacity and mode of failure. The experimental results, generally, indicate that slabs retrofitted using CFRP sheets restored flexural strength values nearly equal to or lower than those of the reference slabs, the retrofitted slabs exhibited larger deflection than the control slabs at ultimate loads. Retrofitted control slabs after loading regained about 93.95% to 97.92% of their original load capacity(before retrofitting) while the other slabs regained from 42.% to 84% of the load capacity of the original control specimens. Most of the tested slabs failed by concrete crushing at mid span and partial debonding of certain retrofitting systems was also observed for a few cases

This study investigate the behavior of six beams (solid or with opening) of dimension (length 1000 x height 180 x width120mm) simply support under partial uniformly distributed load, four of these beam contain long opening of varied section (40x40mm) or (80x40mm). The effect of vertical steel reinforcing, opening size and orientations are investigated to evaluate the response of beams. The experimental behavior based on load-deflection measured at central and quarter of tension zones. The experimental test result shows the presence of Hollow decrease the load carrying capacity by about (37.14% to 58.33%) and increased the deflections by about (71.6% for (Hollow ratio 7.4%) to 75.5% for (Hollow ratio 14.8%)) for same applied loadcompared with solid beams with the same properties. The increase shear steel reinforcing will decrease all the deformations at all stages of loading, but particularly after initial cracking and give enhancement in ultimate load capacity of beams by about 31.5% with increasing the amount of shear steel reinforcing by about 50%. Finally, ductility is increased in all cases under partial uniformly distributed load when hollow ratio decreased by about 50% or increased in shear steel reinforcing by about 50%

In this study, the feasibility of Forward–Reverse osmosis processes was investigated for treating the oily wastewater. The first stage was applied forward osmosis process to recover pure water from oily wastewater. Sodium chloride (NaCl) and magnesium chloride (MgCl2) salts were used as draw solutions and the membrane that was used in forward osmosis (FO) process was cellulose triacetate (CTA) membrane. The operating parameters studied were: draw solution concentrations (0.25 – 0.75 M), oil concentration in feed solution (FS) (100-1000 ppm), the temperature of FS and draw solution (DS) (30 - 45 °C), pH of FS (4-10) and the flow rate of both DS and FS (20 - 60 l/h). It was found that the water flux and oil concentration in FS increase by increasing the concentration of draw solutions, the flow rate of FS and the temperature for a limit (40oC), then, the water flux and oil concentration decrease with increasing the temperature because of happening the internal concentration polarization phenomenon. By increasing the oil concentration in FS and the flow rate of the DS, the water flux and oil concentration in FS decreased, while it had a fluctuated behavior with increasing pHof oily wastewater. It was found also that MgCl2 gives water flux higher than NaCl. So the values of resistance to solute diffusion within the membrane porous support layer were 55.93 h/m and 26.21 h/m for NaCl and MgCl2 respectively. The second stage was applied reverse osmosis process using polyamide (thin film composite (TFC)) membrane for separating the fresh water from a diluted (NaCl) solution using different parameters such as draw solution concentration (0.08–0.16 M), feed flow rate (20–40 l/h).

Moving the 15-minute city beyond the urban core: the role of accessibility and public transport in The Netherlands
Authors: Poorthuis Ate , Zook Matthew
Published: June 2023

The 15-minute city – providing every resident’s daily needs within a 15-minute walk, cycle or public transportation ride – has recently gained popularity among policy makers as a means for a more sustainable and just future. While the goal of a more equitable and sustainable city is laudable, we note that half of the world’s population (still) lives in non-urban areas and thus seek to explore how the concept of the 15-minute city might extend into suburbs, exurbs and even the countryside. We do this via an empirical analysis of 16 years of travel survey data in the Netherlands and evaluate the relevance of the 15-minute city concept in non-urban areas. We frame our analysis via three specific aspects of the 15-minute concept: (i) differences in reliance on cars in urban and non-urban areas; (ii) differences in extra travel time across the urban-rural continuum if all car-based trips were replaced by public transport; and (iii) the effect of accessibility of goods and services on extra travel time if all car-based trips were replaced by public transport. Based on our findings, we argue that practical implementations of the 15-minute city (focused on the urban core) risk missing the particular challenges facing non-urban neighborhoods, especially in terms of car reliance. As planners rush to address the affordable housing crisis in the Netherlands and elsewhere, these short-comings highlight the importance of expanding research and policy practice in terms of scope (i.e. including non-urban areas) and focus (i.e. considering other reasons for individual travel beyond goods and services) to better reflect the lived experience of people across all geographies.
