Lemongrass Oil Enhances the Storage Efficacy of Phosphine-Treated Grains Wheat

Under environmental conditions of Burj El-Arab warehouse, Alexandria Governorate, Egypt, a storage experiment was carried out from 30 May 2020 to 26 February 2021 to become conscious of the effect of treatment with some chemical compounds (insecticides) i.e. deltamethrin at 1 and 2 ppm, malathion at 10 and 15 ppm and phosphine at 3 and 5 tablets/m and natural compounds (botanical oils) i.e. clove, coriander and lemongrass oils at 10 and 15% on storage efficiency of wheat after 9 months from harvesting time. The experiment had arranged in a factorial experiment in a randomized complete block design (RCBD) with three replications. The lowest insect infestation percentage and grains weight loss percentage and highest number of dead insects/samples were resulted from treating wheat grains with phosphine at 5 tablets/m. Treating wheat grains with lemongrass oil at the rate of 15% recorded the lowest insect infestation percentage and grains weight loss percentage and highest number of dead insects/sample. This study recommended treating samples of wheat grains with phosphine at 5 tablets/m besides lemongrass oil at 15% to enhance storage efficacy characters under the environmental conditions of Burj El-Arab district, Alexandria Governorate, Egypt.
Race in education policy: school safety and the discursive legitimation of disproportionate punishment

ABSTRACT Interventions instated to disrupt the destructive effects of the school-to-prison pipeline on students of color were repealed as a result of the US Education Department’s 2018 Federal Commission on School Safety report. Using a critical policy and critical discourse framework, this paper examines how the language used in the report facilitated the process of repeal while concealing the insidious effects that the repeal could have on students of color and especially black students. Based on this analysis, the paper argues that education policy discourse is influenced by and supports the covert operation of white supremacist ideological structures that hinder the struggle for equity and justice in education.
Children's ideas about the ozone layer and opportunities for physics teaching

The potential of global environmental issues as starting points for learning curriculum science is examined by studying the preconceptions of children (aged 12-13) about the nature, functions and vulnerability of the ozone layer. Most children are familiar with the general location and nature of the ozone layer, but less informed about its magnitude and that of the 'holes'. Many children think that 'pollutants' in general damage the ozone layer and some confuse ultra-violet radiation with heat
THE COVID-19 IMPACTS ON THE HOSPITALITY INDUSTRY HIGHLIGHTS FROM EXPERTS IN PORTUGAL

Purpose - To better understand the impact of COVID -19 on the tourism sector, with a focus on the hospitality industry, and how these changes will affect the sector and business responsiveness. Design - This is research focusing on the COVID-19 impacts on the hospitality sector in Portugal. The study reports in detail how a group of experts perceived this critical situation caused by the pandemic. Methodology - For data collection, a focus group was conducted with six experts in the field. A thematic analysis was conducted to interpret the data and NVivo software was used to organise and define the themes. Findings - Experts emphasised the massive collective dismissals in large hotel chains, the possible loss of 50 million jobs in the tourism sector, and the negative impact on the entire value chain. The low occupancy rate had a negative financial impact, as total revenues in the sector plummeted by more than 70% compared to the previous year. This pandemic required significant adjustments from operations to ensure safe operations. Participants not only stressed the importance of motivating and bringing teams together, but also described strategies to increase employee engagement. Another area of growth during the pandemic was food delivery platforms. Originality of the research - This is the first time research describing economic, financial, organizational, operational, and technological impact of COVID -19 on the hospitality industry. Hopefully these study results will help hotel and restaurant managers better plan their strategy following this pandemic.
Cultivating a Healthy Living Environment for Adolescents in the Post-COVID Era in Hong Kong: Exploring Youth Health Needs

Studies have shown that adolescents now have a higher exposure to health risks than those in the past, and Hong Kong adolescents are no exception, particularly with the social crisis in 2019 and then the COVID-19 pandemic in 2020. Data from health care services for children and adolescents only represent the tip of the clinical iceberg, and health profiles, including living habits, lifestyles, data on health status, and health service utilization, are not always readily available for effective planning to cultivate a healthy living environment. In this paper, an exploratory study on secondary school students was conducted in one district of Hong Kong that has the potential and resources to become a healthy city. Students were found to have a high prevalence of poor sleep quality and quantity; excess screen time; physical inactivity; an insufficient intake of healthy food; emotional disturbance, including symptoms of post-traumatic stress disorders (PTSDs); and irregular attendance to student health services. A multivariate analysis showed that excessive time on social media websites, short sleeping hours, symptoms of PTSD, and a lack of regular exercise were independently associated with emotional distress. Youth service providers should re-orientate student health services, moving away from routine services to be more outreaching in order to cultivate a supportive living and learning environment, promoting better health for adolescents.
Temporal Transferability of Model Components within an Activity-Based Travel Demand Modelling Approach

Temporal transferability is one of the key and implicit conditions of developing travel behaviour models as these are developed for forecasting future levels of transport demand. Current travel demand modelling practices are focusing on the development of advanced models that better explain current behaviour rather than an emphasis on the ability of these models in forecasting. The importance of producing high temporal transferability of models should not be neglected as these models are used by planners and policy-makers to test policy decisions and to estimate future demands, which are critical inputs for infrastructure planning and maintenance. This research presents an investigation of the temporal transferability of activity generation process, scheduling process, and mode choice models. Three repeated cross-sectional household travel survey datasets collected in the greater Toronto and Hamilton area (GTHA) are used for the investigation. A multiple discrete-continuous extreme value model is used to develop an activity-travel generation model, and separate models are
In-situ Lu – Hf geochronology of calcite

Abstract. The ability to constrain the age of calcite formation is of great utility to the Earth Science community, due to the ubiquity of calcite across a wide spectrum of geological systems. Here, we present the first in-situ laser ablation inductively coupled tandem mass spectrometry (LA-ICP-MS/MS) Lu–Hf ages for calcite, demonstrating geologically meaningful ages for IOCG and skarn mineralisation, carbonatite intrusion and low grade metamorphism. The analysed samples range in age between ca. 0.9 Ga and ca. 2 Ga with uncertainties between 1.4 % and 0.5 % obtained from calcite with Lu concentrations as low as ca. 0.5 ppm. The Lu–Hf system in calcite appears to be able to preserve primary precipitation ages over a significant amount of geological time, although further research is required to constrain the closure temperature. The in-situ approach allows calcite to be rapidly dated while maintaining its petrogenetic context with mineralization and other associated mineral processes. Therefore, LA-ICP-MS/MS Lu–Hf dating of calcite can be used to resolve the timing of complex mineral paragenetic sequences that are a feature of many ancient rock systems.
delayed proton decay of 24Si

A novel experimental approach has been employed for the measurement of $\ensuremath{\beta}$-delayed protons from ${}^{24}\mathrm{Si}$ produced via the fragmentation of a ${}^{28}\mathrm{Si}$ beam with an energy of 100 MeV/nucleon. The secondary beam of ${}^{24}\mathrm{Si}$ was separated by the projectile fragment separator RIPS at RIKEN and was implanted in a 2.6 $\ensuremath{\mu}\mathrm{m}$ aluminum foil placed parallel to a gas-$\ensuremath{\Delta}E$ and silicon-$E$ detector telescope for the measurement of delayed protons. The above arrangement has led to a very clean, $\ensuremath{\beta}$-ray background free delayed proton energy spectra and a few new proton peaks could be identified from the decay of ${}^{24}\mathrm{Si}. $
DS-SWIPT: Secure Communication with Wireless Power Transfer for Internet of Things

Internet of Things (IoT) is promptly spreading and reaching a series of domains, including many industrial applications designed for monitoring purposes. In such networks, sensitive information is being collected and transmitted by IoT devices with limited resources, which leads energy efficiency and cybersecurity to become critical. Therefore, this paper proposes a novel approach for wireless communications and power for IoT monitoring applications with the aim of achieving energy efficiency and security. The proposed solution combines the advantages of Simultaneous Wireless Information and Power Transfer (SWIPT) for wireless power transfer to remote IoT devices and Direct Sequence Spread Spectrum (DSSS) for data confidentiality. The proposed DS-SWIPT is a security improvement over the original SWIPT. Simulation results show that the proposed DS-SWIPT can achieve energy efficiency along with acceptable data confidentiality.
Characterization of quaternary Heusler alloys CoFeYGe (Y = Ti, Cr) with respect to structural, electronic, magnetic, mechanical, and thermoelectric features

The electronic, magnetic, elastic, and thermoelectric properties of CoFeYGe (Y = Ti, Cr) quaternary Heusler compounds are studied using DFT simulations. Our calculations show that both CoFeYGe (Y = Ti, Cr) alloys have a Type‐I atomic configuration. CoFeCrGe and CoFeTiGe compounds with band gaps of 0.640 eV and 0.489 eV, respectively, were found to display half‐metallic behavior in the minority spin channels. The total magnetic moment of CoFeCrGe was 3.00 μB, while CoFeTiGe's was 1.00 μB. CoFeTiGe and CoFeCrGe are both mechanically stable in the Y‐Type‐I structure. The surface of E is entirely distorted, demonstrating substantial anisotropy for two compounds. They have a higher anisotropic Young's modulus in the (XY), (XZ), and (YZ) planes. At 900 K, ZT is 0.31706 (0.45308) for CoFeTiGe (CoFeCrGe), corresponding to a carrier concentration of n0 = 20.4581 × 1021 cm−3 (64.5856 × 1021) cm−3. Two ways exist to enhance ZT values of CoFeTiGe and CoFeCrGe to 0.4032 and 0.64149, respectively: A charge carrier concentration of 17.392 × 1021 cm−3 for CoFeTiGe and 59.503 × 1021 cm−3 for CoFeCrGe is obtained. The second similar result is obtained by raising the chemical potential of CoFeTiGe and CoFeCrGe by 0.068 and 0.980 Ryd, respectively. To our knowledge, CoFeCrGe and CoFeTiGe exhibit exceptional spintronic and thermoelectric properties.
The efficacy and acceptance of online learning vs. offline learning in medical student education: a systematic review and meta-analysis

Background: To maintain the continuity of medical education during the COVID-19 epidemic, online learning has replaced traditional face-to-face learning. But the efficacy and acceptance of online learning for medical education remains unknown. This meta-analysis aimed to assess whether online learning improves learning outcomes and is more acceptable to medical students compared to offline learning. Methods: Four databases were searched for randomized controlled trials (RCTs) and comparative studies (non-RCTs) involving online learning published from January 1900 to October 2020. A total of twenty-seven studies comparing online and offline learning in medical students were included. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework and Newcastle-Ottawa Scale (NOS) were used to assess the methodological quality of RCTs and non-RCTs respectively. The data of knowledge and skills scores and course satisfaction were synthesized using a random effects model for the meta-analysis. Results: Twenty-one RCTs that were judged to be of high quality according to the GRADE framework and six non-RCTs studies which ranged from 6 to 8 (NOS) and can be considered high-quality were included in this meta-analysis. The revealed that the online learning group had significantly higher post-test scores (SMD =0.58, 95% CI: 0.25 to 0.91;P=0.0006) and pre-and post-test score gains than the offline group (SMD =1.12, 95% CI: 0.14 to 2.11, P=0.02). In addition, online education was more satisfactory to participants than the offline learning (OR: 2.02;95% CI: 1.16 to 3.52;P=0.01). Subgroup analysis was performed on knowledge and skill scores at the post-test level. The selected factors included study outcome, study design and type, participants, course type and country. No significant factors were observed in the subgroup analysis except for course type subgroup analysis. Discussion: Online learning in medical education could lead to higher post-test knowledge and skill scores than offline learning. It also has higher satisfaction ratings than offline education. In conclusion, online learning can be considered as a potential educational method during the COVID-19 pandemic. However, given the risk of bias of included studies such as the inclusion of non-randomized comparative studies, the conclusion should be made with cautions.

Antimicrobial and Enzymatic Profiling of Halophilic and Halotolerant Bacteria from a Hypersaline Lake ‘The Great Sebkha of Oran, Northwestern Algeria’

Abstract Extreme ecosystems such as hypersaline habitats are promising source of bacteria able to produce potent natural molecules. Halophilic and halotolerant bacteria associated with an unexplored dry salt lake in Algeria have been investigated. A total of 17 isolates were phenotypically characterized. Optima temperature, pH, and salt concentration for growth have been determined. Bacteria strains have been identified based on the 16S rRNA gene sequencing. Enzymes production and antimicrobial activity against bacteria and fungi strains have been investigated. The results showed that isolates were assigned to three phylotypes, within eight isolates belonging to the genus Virgibacillus, eight isolates to Bacillus, and the genus Halomonas with one representative isolate. All phylotypes were able to thrive on large scales of salt, temperature and pH. In addition, the screening of extracellular enzymes showed that all the isolates were able to produce at least two enzymes. The gelatinase, and caseinase activities were the most produced. The screening of antimicrobial compounds production revealed that these strains exhibited significant activity against Gram-positive, Candida albicans, Fusarium, and Penicillium species. Finally, this biotechnological profiling and the PCA analysis have been shown that LMB3038, LMB3095, and LMB3082 were the most performant strains and present a promising source of important molecules.
Influences of Iqbal’s Purview of Khudi on Individuals’ Psycho-Socio-Emotional Development

The ever-changing paradigms of today’s modern world, pertaining to the study of man have much-caused chaos and confusion in the minds of the masses affecting their social, emotional, psychological, and spiritual development. This situation warrants the introduction of Iqbal’s philosophy about selfhood (Khudi), which provides holistic and all- encompassing solutions for today’s man. Therefore, the purpose of this research is to highlight the social, emotional, psychological, and spiritual teachings of Iqbal’s poetry and provide help in the personal and social development in today’s dilemma. For data analysis content analysis approach has been used. Relevant themes have been generated from Iqbal’s poems and sayings. Findings reveal that within the Iqbalian preview, character building has much to do with perseverance and patience for controlling emotions. Manipulation of feelings guiding to virtuous morals would also lead one to have a mystically and mentally healthy life. The findings of the study also highlight that Iqbal’s ideas on social, emotional, psychological, and spiritual development are much in line with the spirit of Islamic teachings. Moreover, his idea on man is more dynamic in nature and can yield positive effects when applied in the fields of education, motivation, human capital development. Keywords: Psychological, Social, Emotional, Spiritual, Development, Iqbal
Who Covers the Qualifications of Female Candidates? Examining Gender Bias in News Coverage Across National and Local Newspapers

This article examines differences in news coverage of female candidates using a media sociology framework that examines the interplay between organizational, routine, and individual levels of influence. The analyses find that national and local newspapers are more likely to write about the political qualifications of female candidates relative to male candidates, and female journalists at local newspapers are most likely to write about women’s political qualifications. Female candidates receive more feminine stereotypic coverage across newspapers, especially in all-women elections. These results uncover important differences across media organizations that affect how female candidates develop their campaign strategies and voter decision-making.
Research problems in Biological Anthropology: Flaws in sampling and in methods of results analysis

Anthropology has as ambition the study of the whole of humanity. It includes several specialties and sub-specialties that, despite their differences, offer an overall perspective that requires a holistic research approach. In Biological Anthropology, one of its specialties, anthropologists study biological variations in contemporary human populations in order to reveal their characteristics and their genetic relationships and to try, on the basis of analysis of these variations and those revealed in human fossils, to trace the evolution of human lineage through time. In this report, I provide an overview of some research major problems met in biological anthropology. I evoke especially the problems of the use of uncertain results analysis methods and those of incorrect samplings. In addition to the presentation of these problems and their consequences I present alternatives and suitable solutions. I also explain how some classic considerations resulting from some of these problems could hinder scientific progress in the topic in question. Hence, I believe it is time to avoid these problems, to eradicate the resulting considerations and to follow the most realistic research tracks.
Effects of psychiatric symptoms, age, and gender on fear of missing out (FoMO) and problematic smartphone use: A path analysis with clinical-based adolescent sample

Background: Fear of missing out (FoMO) is a kind of anxiety that arises from FoMO on rewarding online social experiences that others might be having. Recent studies demonstrated that there is a strong relationship between FoMO and problematic smartphone use (PSU). In this study, we aimed to address the relationship between age, gender, psychiatric symptoms, PSU, and FoMO among a clinical-based adolescent sample. Methods: In total, 197 adolescents (136 boys, 12–18 years) who applied to psychiatry clinics were recruited in the study. Path analysis with observed variables was used to investigate the relationships of PSU and FoMO with each other and with psychiatric symptoms (somatization, obsession–compulsion, interpersonal sensitivity, depression, anxiety, phobic anxiety, paranoid ideation, and psychoticism), age, and gender. Results: Path analysis showed that age (B1 = 2.35, P < 0.001), somatization (B1 = 1.19, P < 0.001), hostility (B1 = 0.92, P = 0.001), and paranoid ideation (B1 = 0.93, P = 0.005) have significant positive effect on PSU, when interpersonal sensitivity has a significant negative effect (B1 = –1.47, P < 0.001). For FoMO, male gender (B0 = 0.35, P < 0.001), anxiety (B1 = 1.37, P < 0.001), and PSU have positive effects, whereas age (B1 = –1.60, P < 0.001), depression (B1 = –0.58, P = 0.004), and hostility (B1 = –0.49, P = 0.001) have a negative effect. Conclusions: Our study demonstrated that although PSU and FoMO are closely related to each other in previous studies, they have different associations with age, gender, and psychiatric symptoms among a clinical-based adolescent sample. The positive effects of PSU, anxiety on FoMO are predictable; however, the negative effect of age, hostility, and depression on FoMO was interesting. These relationships could be related to social exclusion-hostility and impulsivity-male gender/younger age associations in adolescence. In addition, we did not find a significant effect of FoMO on PSU, this could be related to the social and non-social use of smartphones, and should be reevaluated in clinical samples in the future.
Temporal evolution of critical traits and their relationship to cod stock collapse and recovery

The North Atlantic Fisheries Organization response to a precipitous decline of the Flemish Cap cod (Gadus morhua) stock during the 1990s was the imposition of an 11-y moratorium on directed fishing for cod; recovery followed. Over the three decades that encompassed the pre-collapse, collapse and recovery stages, we found that the cod stock status was characterized by four traits: spawning stock biomass, maturity- and weight-at age, and recruitment. The temporal evolution of these traits was consistent with a density dependent conceptual model suggesting phenotypic plasticity was at play during the rebuilding of the stock. The temporal progression of the broader fish community paralleled that of cod, underlying its key ecosystem position. The same demographic variables defined the state of the adjacent Northern Cod stock which underwent a similar pattern of decline, an intermittent moratorium but only partial recovery. This partial recovery is possibly related, in part, to declines of prey species brought about by excessive harvesting after the cod collapse and an apparent collapse of capelin, a major dietary component.
