Authors: Mishra Abhinav , Sharma Vivek Kumar , Singh Jagbeer
Published: March 2023

This is the era of technological advancement, so for every problem, there might exist a solution that is capable of solving the problem with ease by technology. One such problem is the quick availability of blood in case of emergency. Many blood donation applications provide various functionalities but lack on some grounds. Some of these concerned problems are safety, privacy and quick and right availability of help. The contact information of the blood donors can be easily compromised, which caused them many troubles. The Red Wings is made to keep privacy and ensure the safety of both the donor and receiver. This proposed application provides support for all emergencies and focuses on timings also. The major goal of this application is to connect Blood Banks and donors with recipients through verified hospitals, camps and alternative arrangements to avoid any wrong action. This application was made with ease by Android studio and Java frameworks both along with the use of major technologies like Firebase.
Effects of brain breaks on EFL students’ writing skills at the tertiary level
Authors: Orellana Parra Nancy , Vega Melita
Published: March 2023

There is increasing evidence for the connection between emotion, social functioning, and cognition in the education system. Research suggests that the application of brain breaks is a bridge between these relations and academic achievement and can serve as a viable approach to enhancing learners’ outcomes. However, existing studies on this approach are generally from elementary and secondary levels, thus leaving a gap in reports in higher level educational contexts. For the present study, an EFL university class was chosen as the sample subject of study to demonstrate the impact of brain breaks on students’ writing outcomes. Data were collected from both an experimental and control group during an 8-week intervention through a pre-test and a post-test. Qualitative data was collected through teacher observation and students’ surveys. Thus, an embedded sequential mixed methods design was implemented to understand the participants’ perceptions within the context of an experimental intervention. Given that university students spend more than 2 hours sitting, this study suggests that short brain breaks every 45 minutes enhanced cognitive operations associated with writing academic performance.

Authors: Ramadhani Farchan Mushaf Al , Jalil Abdul
Published: March 2023

Sistem pertanian yang ada saat ini hanya mengandalkan pengetahuan para petani dalam mengetahui usia tanaman padi dan masih belum ada teknologi tepat guna yang dapat menganalisis usia tanaman padi. Oleh karena itu, indeks vegetasi yang didapatkan dari citra kamera digital yang tergolong dalam ground-based remote sensing merupakan salah satu metode alternatif yang dapat digunakan dalam menganalisis usia tanaman padi. Penelitian ini bertujuan untuk mengetahui model indeks vegetasi yang paling efektif dalam menganalisis usia tanaman padi. Penelitian ini dilakukan di lahan milik petani di Desa Kebonsari Kecamatan Sumbersari Kabupaten Jember. Sampel citra tanaman padi yang digunakan secara keseluruhan berjumlah sebanyak 400 citra. Analisis uji statistik menggunakan analisis determinasi untuk mencari koefisien determinasi antara variabel bebas dan variabel terikat. Varibel bebas pada penelitian ini yaitu data usia tanaman padi terukur sedangkan varibel terikat adalah indeks vegetasi. Hasil penelitian menunjukkan bahwa indeks vegetasi yang efektif untuk menganalisis usia tanaman padi menggunakan kamera digital yaitu indeks VARI. Selain itu, diperoleh juga bahwa usia tanaman padi varietas Cibogo proporsional terhadap nilai VARI hingga usia tanaman padi mencapai 78 HST. Pada usia tanaman padi 1-78 HST nilai indeks VARI mengalami peningkatan dan kemudian nilai indeks VARI mengalami penurunan hingga usia tanaman padi siap panen. Pola grafik yang didapatkan berlandaskan data hasil penelitian yakni parabolik dengan pendekatan fungsi parabolik y = -0.0002x2 + 0.0292x – 0.8001 dengan koefisien determinasi (R2) sebesar 96.8%.

A importância dessas coleções reside no fato de restarem como fontes ímpares do repertório, decorrente da perda de documentação na Itália, sobretudo depois da destruição maciça dos Arquivos Ricordi e Sonzogno em Milão durante a Segunda Guerra Mundial Este ensaio oferece possibilidades de pesquisa no intuito de nortear estudos futuros.
VISIONS PORTUGAISES DU MAROC
Authors: Topa Francisco
Published: March 2023

Pour des raisons qui ne sont pas faciles à comprendre, le Maroc n’est pas un thème fréquent, ni dans la bibliographie ni dans la littérature portugaise. Cet article essaye d’analyser le peu qui a été publié sur le sujet au siècle dernier, suggérant que la vision du Maroc peut être envisagée en deux moments. Le premier, en plus de dévaloriser le territoire, sa culture et ses habitants, tend à souligner les traits portugais restés au Maroc et même à revendiquer les prétendus droits historiques du Portugal. Dans une seconde phase, le Maroc est désormais perçu comme un pays complexe et séduisant, marqué par un compromis entre tradition et modernité. Cette vision apparaît dans des albums photographiques (comme celui d’Alexandre Alves Costa et Álvaro Siza) et dans des livres de voyage (par des journalistes comme Miguel Sousa Tavares et Maria João Ruela ou par des philologues comme Fernando Venâncio). Fait intéressant, et peut-être à contre-courant, le Maroc apparaît aussi dans deux romans récents d’auteurs peu connus (Luís Soares et Miguel Velha Braga) comme un scénario lié au trafic de drogue.
“Against all Odds”-Increasing Demand and Uptake of Immunization Services Among Non-Fully Immunized Children in Northern Nigeria Using a Positive Deviance Approach: Implementation Science Research
Authors:   Centre for Integrated Health Programs (CIHP), Nigeria, Azurunwa Obioma , Yusuf Olakunle ,   Centre for Integrated Health Programs (CIHP), Nigeria
Published: March 2023

Introduction: Children still die from vaccine-preventable diseases. Nigeria contributes 30% of unimmunized children <5 years globally. This study was conducted in 4 Local Government Areas (LGA) in Niger and Gombe States employing the positive deviance (PD) approach to increase vaccination demand in low child immunization coverage settings. Methodology: The was a quasi-experimental study, conducted between December 2019 and April 2021, comparing pre- and post- intervention vaccination uptake after 5 months of intervention among 400 caregivers of non-fully immunized children (CNFIC). We trained 40 caregivers of fully immunized children (CFIC) as mentors using a participatory learning and action tool. The CNFIC were matched in ratio 10:1 with CFIC and exposed to 8 impact meetings and 10 home-visits using communication materials to increase vaccination knowledge. Paired T-test and adjusted odd ratios from logistic regression models were used to determine change in immunization uptake and factors associated with full immunization for age, respectively. Result: A total of 343 CNFIC were successfully followed up during intervention. The age range of children in the study was 2 to 12 months with the female (178) slightly more than the male (165). The mean vaccine uptake rate increased from 43.7% to 85.9% (T= -29.3, P<0.005) with 55.4% fully vaccinated for age post-intervention. Safer LGA residence, being a housewife caregiver, and younger caregivers <30 years were positive determinants of full vaccination. Conclusion: Adopting the PD approach to low uptake vaccination settings can increase vaccination demand and coverage. This approach can be leveraged in other public health challenges.
Disordered Eating and Associated Risk Factors: Profiling Malaysian University Students with Disordered Eating
Authors: Tang Yi-Ting , Liew Jia Xian , Chooi Weng-Tink
Published: March 2023

Disordered eating (DE) refers to a range of troubling eating behaviors that are considered early warning signs of an eating disorder. The current literature warned that university students are at high risk for developing DE. This study aimed to investigate DE among Malaysian university students and its associated factors, including body dissatisfaction (BD), body mass index (BMI), general anxiety, and social appearance anxiety (SAA); particularly, establishing a profile of participants who displayed tendencies of DE. University students aged 18–25 in Malaysia completed the Disordered Eating Examination-Questionnaire (EDE-Q), Contour Drawing Rating Scale (CDRS), Beck Anxiety Inventory (BAI) and Social Appearance Anxiety Scale (SAAS). Their weight and height were also collected. 201 participants (female = 169; Mage = 21.3, SD = 1.34) were recruited. 43 participants (21.4%, 43/201) self-reported regular occurrence (≥ 4 occurrences) of binge episodes over the previous 28 days. 41 (95.3%) of the 43 participants reported BD, and 35 (81.3%) of them expressed a desire to be thinner. Additionally, they scored significantly higher on all four subscales and the Global EDE-Q scale as well as the SAAS, compared with those who self-reported less binge eating. Compared with those who self-reported having experienced less binge eating, those who regularly engaged in binge eating appeared to have significantly higher levels of SAA and four aspects of the psychopathology of DE, including weight, shape and eating concern as well as restraint. BD and the drive for thinness appeared to be prevalent amongst them.

The challenge of comparing pollen-based quantitative vegetation reconstructions with outputs from vegetation models – a European perspective
Authors: Dallmeyer Anne , Poska Anneli , Marquer Laurent , Seim Andrea , Gaillard-Lemdahl Marie-José
Published: March 2023

Abstract. We compare Holocene tree-cover changes in Europe derived from a transient MPI-ESM1.2 simulation with high spatial resolution LPJ-GUESS time-slice simulations and pollen-based quantitative reconstructions of tree cover based on the REVEALS model. The dynamic vegetation models and REVEALS agree with respect to the general temporal trends in tree cover for most parts of Europe, with a large tree cover during the mid-Holocene and a substantially smaller tree cover closer to the present time. However, the decrease in tree cover in REVEALS starts much earlier than in the models indicating much earlier anthropogenic deforestation than the prescribed land-use in the models. While LPJ-GUESS generally overestimates tree cover compared to the reconstructions, MPI-ESM indicates lower percentages of tree cover than REVEALS, particularly in Central Europe and the British Isles. A comparison of the simulated climate with chironomid-based climate reconstructions reveals that model-data mismatches in tree cover are in most cases not driven by biases in the climate. Instead, sensitivity experiments indicate that the model results strongly depend on the tuning of the models regarding natural disturbance regimes (e.g. fire and wind throw). The frequency and strength of disturbances are – like most of the parameters in the vegetation models – static and calibrated to modern conditions. However, these parameter values may not be valid during climate and vegetation states totally different from todays. In particular, the mid-Holocene natural forests were probably more stable and less sensitive to disturbances than present day forests that are heavily altered by human interventions. Our analysis highlights the fact that such model settings are inappropriate for palaeo-simulations and complicate model-data comparisons with additional challenges. Moreover, our study suggests that land-use is the main driver of forest decline in Europe during the mid- and late-Holocene.
Technical Note: Improved synthetic routes to cis- and trans-(2-Methyloxirane-2,3-diyl)dimethanol (cis- and trans-β-isoprene epoxydiol)
Authors: Frauenheim Molly , Surratt Jason D. , Zhang Zhenfa , Gold Avram
Published: March 2023

Abstract. We report improved synthetic routes to the isomeric isoprene-derived β-epoxydiols (β-IEPOX) in high yield (57–69 %) from inexpensive, readily available starting compounds. The syntheses do not require protection/deprotection steps or time-consuming purification of intermediates and can readily be scaled up to yield the target IEPOX isomers in gram quantities. Emissions of isoprene (2-methyl-1,3-butadiene, C5H8), primarily from deciduous vegetation, constitute the largest source of nonmethane atmospheric hydrocarbons. In the gas phase under low-nitric oxide (NO) conditions, addition of atmospheric hydroxyl radical (OH) followed by rapid addition of O2 yields isoprene-derived hydroxyperoxyl radicals. The major sink (> 90 %) for the peroxyl radicals is sequential reaction with hydroperoxyl radical (HO2), OH and O2, which is then followed by the elimination of OH to yield a ~2 : 1 mixture of (2-methyloxirane-cis/trans-2,3-dilyl)dimethanol (cis/trans-β-IEPOX). The IEPOX isomers account for about 80 % of the closed-shell hydroxyperoxyl products, and are rapidly taken up into acidic aerosols to form secondary organic aerosol (SOA). IEPOX-derived SOA makes a significant mass contribution to fine particulate matter (PM2.5), which is known to be a major factor in climate forcing as well as adversely affects respiratory and cardiovascular systems of exposed populations. Prediction of ambient PM2.5 composition and distribution, both in regional- and global-scale atmospheric chemistry models, crucially depends on the accuracy of identification and quantitation of uptake product formation. Accessibility of authentic cis- and trans-β-IEPOX in high purity and in large quantity for laboratory studies underpins progress in developing models as well as identification and quantitation of PM2.5 components.
Navigating Research Enthusiasm in Medical Students Towards Clinically Impactful Articles
Authors: Abdul-Qadeer Muhammad , Ramesh Danish , Samar Mahmood
Published: March 2023

Learning medical research is an integral part of the development of a holistic physician. Though, not all physicians become clinician-scientists, those who do become enjoy significant privileges over their clinician-only counterparts, mainly in terms of faster career progression and higher employability. Though, to produce more well-rounded clinician-scientists, academic physicians and medical scientists need to make themselves available and be willing to work with and mentor medical students. Besides, a curriculum reform is warranted where students should be encouraged to start learning and conducting research in their first year of medical school. To make the process even easier and help scale these ideas, students should be encouraged to replicate previous highly cited studies, as they can provide a walkthrough for students to follow, thereby necessitating lesser supervision while maintaining the clinical impact that can be made with their time and effort.

Background: Clinical white coats worn by the medical students can be contaminated at hospitals and act as a potential reservoir for pathogens including antibiotic-resistant bacteria. This study aimed to identify the contamination rates of clinical white coats worn by medical students with selected potential pathogens and their antibiotic resistant phenotypes.
Methods: A cross-sectional study was done among 151 4th year medical students of Faculty of Medicine, University of Peradeniya, Sri Lanka in September 2020. The participants belonged to two batches undergoing clinical training at two settings. Swabs from pockets and sleeves of the clinical white coats were taken. Potential pathogens and their resistant phenotypes were identified with routine tests.
Results: Fifty-three participants (35.1%) had coats contaminated with Staphylococcus aureus; 15 (9.9%) had coats contaminated with Methicillin-Resistant S.aureus (MRSA).  One Enterobacterales (0.7%) was an AmpC producer.  Enterococcus species were isolated from 19 (12.6%) coats and 2 (1.3%) had coats contaminated with vancomycin resistant enterococci.  Molecular testing on the MRSA isolates identified that 5(20%) of the MRSA isolates were PVL positive while all were mecA positive. Sex, type of clinical appointment, and frequency of washing white coats were not associated with contamination. The “batch” was significantly associated with contamination with S.aureus and Enterococcus species. 
Conclusions: We found that clinical white coats worn by medical students recruited for the study were contaminated with S.aureus, MRSA and Enterococcus species. There was a notably high-rate of contamination with S. aureus.  All MRSA isolates were mecA positive while the rate of PVL positivity was low.
Rivers as Lifeline of Urbanization- An Environmental Case Analysis
Authors: Gupta Tanya , Kesarwani Chandrakala
Published: March 2023

Rivers and water are essential resources for human life, the environment and development of any nation. In India, the significance of rivers as the focal point of human settlement was established from the early times of civilisation and will remain so. Ancient India is always referred as land of seven rivers. Rivers here have religious significance but India’s rivers are depleting at an alarming rate. Riverfronts are not merely unique spaces in a city, but also the most representative region which reflect the local character. Since the industrial revolution, urban population and the need for land have increased rapidly; a good many riverfront spaces have been occupied, resulting in the deterioration of water quality of the rivers. A case study on the degradation of river and their restoration is been explained in this paper using example of Hindon river and Yamuna River. The region of Ghaziabad is plain and lacks topographic prominence. River channels break the monotony of physical landscape. The major sources of waste generation within Ghaziabad largely comprise of residential areas, poor yojna area, vegetable markets industrial and slaughter waste .open dumping of municipal solid waste quiet often in scattered heaps has occupies a larger space near the river . The land around the river Hindon is a breeding ground for pathogens, flies, malodours and generation of which leads to water pollution. The land can be completely bioremedised followed by development of beautiful garden “Eco-Energy Park - Hindon Eco Park” adjacent to Sai Upvan. The research aims at providing landscape solutions to eliminate the further degradation and pollution of nearby soil, air and Hindon river. Today, with the abysmal state of drainage and solid-waste management of the city Delhi, the Yamuna has become a huge drain carrying the waste of this mega city. Millions of rupees have been spent by successive governments in order to clean the river, but to no significant change in the situation. The spaces around the river are also rather ‘lost spaces’ with either agricultural field, derelict power stations, stadiums and memorials. With very high densities in the residential areas, it has to be realized that Delhi is in dire need of a large public open space. The study aims at reconnecting the city to the river not only metaphorically, but to establish physical linkages and improve the quality of the environment and create opportunities to activate the riverfront. The paper will focus on the causes, impact and measures of pollution of rivers in case of Yamuna and Hindon in NCR region
Redefining the ‘Ethics and Aesthetics’ of Concrete in Contemporary ‘Isms’ of Architecture
Authors: Saka Lovejit Singh , Jain Charu
Published: March 2023

This research paper is an ‘embracement of concrete’. It’s about millenniums of evolutionary changes of the material - which is often questioned at being a material - still struggling to get itself defined; getting better, and perhaps new. The paper represents the developments and innovations in concrete; the material which has been at the core of contemporary discussions and experiments, leading to avant-garde horizons exhibiting its capabilities and possibilities. It aims to comprehend the imminent capabilities and dimensions of aestheticized morality of concrete in the contemporary architecture, spurred along its evolutionary process. It’s about knowing the ‘whats’ of concrete and an attempt to provoke discussion and study of the material. Further, the objective is to establish a relation between the developments in concrete, and the developments in architectural languages and philosophies generating the so-called contemporary ‘isms’ of architecture with redefined ‘ethics and aesthetics’ of the material. The analysis contributes valuable sagacity into concrete’s prolonged trajectory as an architectural material and is an insight into what the future for such an ancient material looks like. The overall vision is to anticipate what more is yet to come out from concrete.
Study on the Motherhood in Mercy
Authors: Nazir Sumaira , . Shafayayat
Published: March 2023

Motherhood is worshipped in every society, thus in every context mother is equated to God - a life-giver. Motherhood provides them with the necessary abilities and character to be able to do something useful to others. This paper seeks to investigate the concept of motherhood in Toni Morrison's novel, A Mercy (2008). Morrison, the Nobel laureate, depicts the experiences and hardship of black women in her literary works. In Mercy, the concept of motherhood is broadened to include more than traditional mother-daughter ties. In this tale, mother love takes on a new meaning as a blood connection between all of the female characters. In her work, motherhood is unique, with a wounded spirit and a shattered self. The relationship between mother and kid is not easy, but it is strained. The focus of this study is on the Black mother and the assertive actions she takes to cope with the challenges of hopeless slavery. Morrison illustrates how slavery warped and shaped motherhood through the portrayal of an unconventional mother figure, Minha Mae, and her excruciating experiences, and reveals the circumstances that physically and emotionally separate mother and children. She rejects the conventional concept of motherhood and develops a view of black motherhood that is radically different from motherhood as practiced and prescribed in the dominant culture in terms of both maternal identity and role.

Authors: Oluyemi Omoya Funmilola , Amos Daramola Tolulope
Published: March 2023

Domestic effluents were collected from the kitchen, bathroom, laundry of students’ hostels and the effluents were bacteriologically analysed. The molecular identity and methicillin-resistant gene assay of selected multidrug resistant Staphylococcus aureus strains were conducted via 16S rRNA sequencing. Bathroom effluents obtained from Jadesola hostel had the highest staphylococcal count of 38.04±2.31 CFU/100 ml, while Adeniyi hostel had the least at 1.25±0.05 CFU/100 ml. All presumptive Staphylococcus species isolated from the domestic effluents produced a coagulase-positive outcome. The domestic effluents sourced 2 m away from the original source in FUTA hostels had the Staphylococcus aureus percentage occurrence of 15 % (45.76) whilst a low percentage occurrence was recorded in tap water obtained from the hostel locations at 1 % (8.48%). Staphylococcus aureus isolated in effluents from Abiola male hostel and FUTA staff quarters were resistant to oxacillin at 11.50±0.55 and 12.00±0.00 mm respectively. Staphylococcus aureus strain 1, 2, 6, 7, 8, 13 and 14 were positive with Mec A gene bands at approximately 300 base pairs. The Staphylococcus aureus strains isolated from this study showed phenotypic resistance to oxacillin, a drug proxy of methicillin in Staphylococcal therapy. The unsystematic expulsion of untreated domestic effluents into water channels should be prohibited.

Далеко не все варианты превышали значение существенной разницы, то есть находились в пределах ошибки опыта. Запасы нитратного азота в большинстве вариантов были в пределах 5 – 10мг/кг и оценивались как низкие, подвижного фосфора в пределах 5 – 10 мг/100гр, что оценивается как среднее. Технологии возделывания не показали существенного влияния на содержание элементов питания в почве. Урожайность культур находилась в пределах 24,0 – 9,3ц/га. Максимальную прибавку в урожайности показал фон внесения азотно-фосфорного удобрения на пшенице по гороху и бессменном посеве + 3,7 ц/га по нулевому фону. В среднем по культурам севооборота явного преимущества нулевого фона по урожайности обнаружено не было.

Test development involves many required stages, including examining the psychometric characteristics of the test and each test item. This study describes the development of an English vocabulary test designed for EFL learners in Vietnam and provides an analysis using the Rasch model to evaluate the test quality and test items. The data was collected from 202 students from a Vietnamese university and analysed with the use of the Conquest computer program. The results show that the test had high reliability. Four out of 50 items were removed from the test as not fitting the Rasch model. 36 items were ranked very good, and 10 items require some revision efforts for better distractors. The paper is expected to contribute to the wide application of the Rasch model in the practices of test development and suggest the development of more reliable instruments for EFL learners to assess their vocabulary.

A new smart supramolecular polypeptide copolymer P(Glu-co-Lys) was synthesized by the polymerization of α-amino acids using the N-thiocarboxylic acid anhydride (NTA) method, using the pH dynamic response peptide of L-glutamic acid and L-lysine as a carrier for tumor cells. The drug delivery system activated by external acid can self-assemble (pH 7.4) and disassemble (pH 5.5) under the adjustment of pH to load the drug and control its release. Doxycycline (DOX) and the photothermal reagent hydrophilic quanternary stereo-cyanine (HQS-Cy) were loaded into the peptide copolymer to obtain HQS-Cy/DOX nanoparticles (NPs) for chemo-photothermal therapy. Gentle photothermal heating can enhance the absorption of drugs by cells and enhance the efficacy of chemotherapy. In addition, chemo-photothermal therapy can solve the defect of easy recurrence after single photothermal therapy. The ingenious nanodrug delivery system of HQS-Cy/DOX NPs provides great potential for the improvement of chemo-photothermal therapy and will achieve excellent therapeutic effects in cancer treatment.

Investigations of strongly correlated quantum impurity systems (QIS), which exhibit diversified novel and intriguing quantum phenomena, have become a highly concerning subject in recent years. The hierarchical equations of motion (HEOM) method is one of the most popular numerical methods to characterize QIS linearly coupled to the environment. This review provides a comprehensive account of a formally rigorous and numerical convergent HEOM method, including a modeling description of the QIS and an overview of the fermionic HEOM formalism. Moreover, a variety of spectrum decomposition schemes and hierarchal terminators have been proposed and developed, which significantly improve the accuracy and efficiency of the HEOM method, especially in cryogenic temperature regimes. The practicality and usefulness of the HEOM method to tackle strongly correlated issues are exemplified by numerical simulations for the characterization of nonequilibrium quantum transport and strongly correlated Kondo states as well as the investigation of nonequilibrium quantum thermodynamics.

CLC-7 functions as a Cl−/H+ exchanger in lysosomes. Defects in CLC-7 and its β-subunit, Ostm1, result in osteopetrosis and neurodegeneration. Here, we present the cryogenic electron microscopy (cryo-EM) structure of the human CLC-7/Ostm1 complex (HsCLC-7/Ostm1) at a resolution of 3.6 Å. Our structure reveals a new state of the CLC-7/Ostm1 heterotetramer, in which the cytoplasmic domain of CLC-7 is absent, likely due to high flexibility. The disordered cytoplasmic domain is probably not able to restrain CLC-7 subunits and thus allow their relative movements. The movements result in an approximately half smaller interface between the CLC-7 transmembrane domains than that in a previously reported CLC-7/Ostm1 structure with a well-folded cytoplasmic domain. Key interactions involving multiple osteopetrosis-related residues are affected by the interface change.
