Prácticas estudiantiles de diferenciación social vinculadas a la concepción de juventud, sus problemáticas y consumos culturales en el campo escolar de Tandil, provincia de Buenos Aires, Argentina
Authors: Leivas Marcela 
Published: May 2022

El presente artículo expone los primeros resultados de un trabajo de investigación, que a partir de recuperar los aportes de Pierre Bourdieu, específicamente los planteados en su obra "la Distinción. Criterios y bases sociales del gusto" (1979), busca conocer las "distinciones" vigentes entre las "estrategias estudiantiles" desplegadas por jóvenes que asisten a diferentes escuelas secundarias de la ciudad de Tandil, Buenos Aires, Argentina, y dar cuenta además de la relación que dichas estrategias mantienen con determinado "sistema de enclasamiento". Para ello, se han tomado 96 encuestas cualitativas a jóvenes que asisten a tres escuelas secundarias de la ciudad (una urbana de gestión privada, una urbana de gestión estatal y una sub-urbana de gestión estatal). A pesar de que la indagación ha sido mas amplia, aquí se presentan análisis relacionales sobre su localización geográdica, significaciones sobre la juventud y consideraciones sobre consumos culturales. El análisis cualitativo de los datos relevados ha permitido indicar características específicas de los grupos de jóvenes que aisiten a cada institución, así como también relaciones de cercanía y distancia entre ellos, dando cuenta además de indicios sobre la relación que cada grupo mantiene con alguna de las clases socales que componen la estructura social argentina (kessler, 2016), colocando indicios sobre la configuración del "sistema de enclasamiento" que los determina.

Objective: To determine the effect of social media use on sexual behaviors among undergraduate students in public universities in Imo State, Nigeria.
Materials and Methods: This descriptive cross-sectional study employed multistage sampling technique in selecting 300 undergraduates. Data on social media use and sexual behaviors were collected with self- administered semi-structured questionnaire and analysed using statistical package for social sciences version 22.0. Chi-square test was used to identify statistically significant associations between variables. A p value of < 0.05 was considered significant.
Results: The mean age of respondents was 22.13+ 4.26 years, while 252(84%) were youths (ages 15 to 25 years). The mean age at sexual initiation was 18.25+ 3.67 years. There was 100% awareness of social media, 170 (56.67%) heard about it from friends, while the commonest reasons cited for its use is 213 (71.0%) solving school assignments, while the favorite platforms cited was 102 (91.9%) Facebook. There were statistically significant associations between ever had sex and gender and between use of social media and [the sexually active (p=0.001); type of sexual acts practiced (p=0.000) and number of sexual partners (p=0.000)] respectively.
Conclusions: This study found an association between ever had sex and gender, as well as between use of social media for sexually explicit content and some risky sexual behavior. We recommend that measures such as correct sexuality education should be instituted for these students to help in curbing such use of social media and so minimize risky sexual behaviors and their attendant consequences.

Published: May 2022

Background: Students are usually exposed to all kinds of injury in schools and with inadequate health care services in most schools; administering first aid is important in such emergency situations. Hence, this study was conducted to assess the awareness, knowledge and behavioral perception of first aid among medical students of a tertiary institution in South-eastern Nigeria.
Materials and Methods: This cross-sectional study was conducted among 250 medical students of Gregory University Uturu, Abia state, Nigeria. A structured pre-tested validated questionnaire assessing their awareness, knowledge and attitude was used to collect the data. Data was analyzed using IBM Statistical Package for Social Sciences (SPSS) version 25. Chi-squared test were used to test for associations between socio-demographics, knowledge and attitude of respondents. A p-value of <0.05 was considered significant.
Results: Out of the respondents, 98.4% have heard about first aid before the survey, (52.8%; n=132) have good knowledge of first aid skills, and 94% (n=235) have good attitude towards first aid. 91.2% said they are willing to help if trained while 94% of the respondents felt it was necessary to incorporate first aid in the school curriculum.
Conclusion: Although the students showed good awareness and attitude towards the concept of first aid, there is a gap in their knowledge and application of basic emergency first aid skills. There is a need to incorporate the training of basic first aid skills and basic life support skills in the school’s curriculum to bridge the gap.

Steel Transmission Towers are often used to transmit power from one location to another using electrical conductors. Transmission line towers elevate heavy electrical transmission conductors to a safe height above the ground. Furthermore, all towers must withstand various natural disasters such as wind, earthquakes, and so on. Because towers must support the weight of above lines, they must be strong. As a result, the design engineer has a lot of responsibility, as he or she must develop not only an economical, but also a safe and trustworthy design that can withstand various loads, including its own. The voltage, circuit count, and kind of transmission line tower are used to classify them. The most common configurations used are rectangular and square. The most prevalent type of broad-based tower is the square type. Different sorts of towers are introduced in this. Transmission towers are often built of steel or galvanized steel. Lattice structures are commonly utilized and have a sleek body made up of polygonal tubular sections with tubular cross arm management for fastening the tension or suspension clamp. The geometric parameters of transmission line tower configuration include the tower's height, base width, top-hamper width, length, and depth of the cross arm. The leg and bracing elements are the main components of the lattice tower. They transport the tower's vertical and shear stresses to its foundation. Secondary or redundant bracing members are utilized to offer intermediate support to primary members in order to reduce unbraced length and boost load carrying capability. Rectangular and square configurations are the most common. The most frequent are square-shaped broad-based towers. STAAD PRO V8i was used to construct and analyze a standard steel latticed skyscraper of height 19 meters. On post-processing mode after load analysis The bending moment and shear forces findings were obtained, examined, and updated to meet the requirements.

Published: May 2022

In drought situation, farmers in Irrigated ecosystem often faced financial losses due to uncertainty of occurrence of drought event. With the intention of minimizing impact of drought through application of science and technology, drought management plans are implemented by government. The outcome of government supported mitigation strategies was studied. The result revealed that only less number of farmer have adopted technological mitigation strategies on their own. Conducting demonstrations, trainings and supply of critical mitigation inputs through development departments must be continued to educate the farmers to adopt the mitigation measures.
Asymptomatic COVID-19 Infection Induced First Episode Psychosis: A Case Series
Authors: Das Riyal , Mukherjee Aniket , Sarkhel Sujit , Roy Paramita , Bhattacharyya Amit Kumar 
Published: May 2022

Aims: We presented 3 similar cases of 1st episode psychosis that occurred after Corona Virus Disease -2019 (COVID-19) infection which we treated at our institute’s on going post-COVID-19 mental health clinic, to provide more evidence to the existing literature and to describe whether an asymptomatic COVID-19 infection can also induce psychosis in previously healthy individuals and tried to elaborate the probable etiology and nature of the psychotic symptoms.
Presentation of the Cases: All the 3 cases had COVID-19 infection, few days before their psychotic symptoms started for the 1st time. They didn’t have any history of regular substance or medication use that are known to induce psychosis or any previous history of psychiatric disease or family history of psychiatric disease, without any abnormality in physical examinations and laboratory investigations. All the cases had history of stress which were not overwhelming (except the 3rd case) and were mostly related to COVID-19 infection and pandemic associated social and financial stress. 1st case (54 years, married male) developed delusion of persecution, delusion of reference, 2nd and 3rd person auditory hallucinations, 2nd case (61 years, widower male) developed delusion of persecution, 2nd person auditory hallucination (commanding type), disinhibited behaviour (disrobing in public) and the 3rd case (32 years, unmarried male) developed delusion of persecution and delusional misidentification (Intermetamorphosis). All of them responded well to commonly used antipsychotics within 4 weeks that prompted a diagnosis of Acute and Transient Psychotic disorder according to ICD-10 criteria.
Discussion: This study points out that even an asymptomatic COVID-19 can induce psychosis for the first time in life, where the etiology most probably is the direct effect of the virus itself on brain or the COVID-19 and pandemic related stress which is supported by the fact that factors like family history of psychiatric disease, substance use or medication use or any comorbidity that can induce psychosis were also absent. The psychopathological findings were persecutory delusion and auditory hallucinations with one case having Intermetamorphosis phenomenon which is a rare finding and perhaps a novel finding in post-COVID-19 Psychosis.
Conclusion: All COVID-19 infected individuals should be screened early for appearance of any symptom that raises the suspicion of psychosis. Large studies are needed to ascertain the etiology of post-COVID-19 psychosis.

Published: May 2022

A necessidade de preparar-se para eventos futuros vem levando cidades de todo o mundo – entre elas, Salvador, na Bahia – a elaborarem e implementarem suas estratégias de resiliência; planejamentos a longo prazo em busca de um desenvolvimento que seja, de fato, sustentável. Entretanto, no ano de 2020, o planeta foi surpreendido pela Pandemia do COVID-19. Desta forma, o presente trabalho tem como objetivo analisar como Salvador elaborou sua estratégia para enfrentamento de eventos extremos ligados à saúde e como lidou com a situação na prática, ao surgir a situação de emergência. A pesquisa foi realizada por meio de revisão bibliográfica voltada à resiliência, pandemias e territórios, assim como da análise de conteúdo do documento Plano Salvador Resiliente e do site Salvador contra o Coronavírus. Foi possível constatar que, não obstante a cidade não tenha se preparado expressamente em relação a epidemias e pandemias em suas estratégias de longo prazo, quando do surgimento de uma emergência em saúde, foi capaz de incorporar os princípios ali definidos para uma ação emergencial que considerou as vulnerabilidades sociais identificadas no território.

Published: May 2022

Abstract
The period 2021–2030 has been designated the UN decade of ecosystem restoration. A landscape‐scale peatland restoration project is being undertaken on Chat Moss, Greater Manchester, UK, with conservation translocations an important component of this work. The Manchester Argus Coenonympha tullia ssp. davus, a specialist butterfly of lowland raised bogs in the northwest of England, UK is under threat due to severe habitat loss and degradation. A species reintroduction was planned for spring 2020.
This study aimed to quantify the resource thresholds for C. tullia, in order to assess potential risks for the project. Thirteen peatland habitat patches with either recent historic or current C. tullia populations were surveyed for biotic and abiotic factors based on previous qualitative research on the species’ requirements.
Percentage cover of two habitat resources was found to be the strongest predictor in models of C. tullia presence: cross‐leaved heath Erica tetralix and hair's‐tail cotton‐sedge Eriophorum vaginatum.
Critical inflection points on logistic regression curves were used to make quantitative estimates of the minimum requirement of each resource for population survival and the near‐optimum abundance of each resource.
The results of this study improve our understanding of C. tullia’s ecology and the restoration of peatlands for its reintroduction. Additionally, the method has wider utility for the quantitative assessment of habitat readiness before attempting species reintroductions.

AbstractAqueous zinc ion batteries (ZIBs) have been extensively investigated as a next‐generation energy storage system due to their high safety and low cost. However, the critical issues of irregular dendrite growth and intricate side reactions severely restrict the further industrialization of ZIBs. Here, a strategy to fabricate a semi‐immobilized ionic liquid interface layer is proposed to protect the Zn anode over a wide temperature range from −35 to 60 °C. The immobilized SiO2@cation can form high conjugate racks that can regulate the Zn2+ concentration gradient and self‐polarizing electric field to guarantee uniform nucleation and planar deposition; the free anions of the ILs can weaken the hydrogen bonds of the water to promote rapid Zn2+ desolvation and accelerate ion‐transport kinetics simultaneously. Because of these unique advantages, the cycling performance of the symmetric Zn batteries is greatly enhanced, evidenced by a cycling life of 1800 h at 20 mA cm−2, and a cycle lifespan of 2000 h under a wide temperature window from −35 to 60 °C. The efficiency of this semi‐immobilizing strategy is well demonstrated in various full cells including pouch cells, showing high performance at large current (20 A g−1) and wide temperatures with extra‐long cycles up to 80 000 cycles.

AbstractThe development of boron/nitrogen‐based polycyclic heteroaromatic emitters with multiple‐resonance thermally activated delayed fluorescence (MR‐TADF) property can efficiently promote the advancement of high‐efficiency organic light‐emitting diodes (OLEDs) with narrowband emission. Herein, a simple strategy to achieve four ternary boron/nitrogen‐based polycyclic heteroaromatic emitters (SBON, SBSN, DBON, and DBSN) from pure blue (463 nm) to yellow (553 nm) via tuning the coordination between B/N and heteroatom (O or S) is demonstrated, aiming to increase charge transfer delocalization of the polycyclic heteroaromatic emitters and adjust photo‐physical properties. This strategy endows the four emitters with full width at half maximum (FWHM) of 24, 27, 20, and 28 nm, respectively. Additionally, double‐boron type green and yellow narrowband emitters (DBON and DBSN) possess 98% photoluminescence efficiencies in doped films. Besides, considerable rate constants of reverse intersystem crossing (RISC) are achieved because of the small singlet–triplet excited state energy gap and large spin–orbit coupling values. Consequently, the OLEDs covering from blue to yellow based on these emitters show the maximum external quantum efficiency of 13.7%, 17.6%, 26.7%, and 21.8%, respectively, with low‐efficiency roll‐off. These results provide a feasible design strategy to construct boron/nitrogen‐based polycyclic heteroaromatic MR‐TADF emitters for efficient OLEDs with color‐tuning electroluminescence.

AbstractInterface modification of perovskite solar cells (PSCs) has been widely explored not only to achieve defect passivation but also to facilitate charge transport and stabilize the physical/electrical contact at device interfaces. In this study, [2‐(9H‐carbazol‐9‐yl)ethyl]phosphonic acid (CEPA) is introduced as an interface modifier at the interface of perovskite and the hole transporting material (HTM) layer into n‐i‐p PSCs. CEPA reduces surface traps, manipulates the surface dipole for energy‐level alignment, and induces molecular interaction at the interface of the CEPA‐HTM for enhanced interfacial adhesion energy and good mechanical stability. The power conversion efficiency of interface‐optimized PSC is 23.6% using a 2D/3D perovskite structure, representing the highest efficiency among poly(triarylamine) HTM‐based devices. The encapsulated CEPA‐treated PSCs maintain nearly 90% of their initial efficiency during a damp heat lasting for more than 1530 h and retain their initial efficiency during continuous operation under illumination.

AbstractColloidal quantum dots (QDs) consisting of precious‐metal‐free elements show attractive potentials towards solar‐driven CO2 reduction. However, the inhibition of hydrogen (H2) production in aqueous solution remains a challenge. Here, we describe the first example of a carbon–carbon (C−C) coupling reaction to block the competing H2 evolution in photocatalytic CO2 reduction in water. In a specific system taking ZnSe QDs as photocatalysts, the introduction of furfural can significantly suppress H2 evolution leading to CO evolution with a rate of ≈5.3 mmol g−1 h−1 and a turnover number (TON) of >7500 under 24 h visible light. Meanwhile, furfural is upgraded to the self‐coupling product with a yield of 99.8 % based on the consumption of furfural. Mechanistic insights show that the reductive furfural coupling reaction occurs on surface Zn‐sites to consume electrons and protons originally used for H2 production, while the CO formation pathway at surface anion vacancies from CO2 remains.

AbstractStructurally diverse acylations have been identified as post‐translational modifications (PTMs) on histone lysine residues, but their functions and regulations remain largely unknown. Interestingly, in nature, a lysine acylation analog, pyrrolysine, is introduced as a co‐translational modification (CTM) through genetic encoding. To explore this alternative life form, we created a model organism Saccharomyces cerevisiae containing site‐specific lysine CTMs (acetyl‐lysine, crotonyl‐lysine, or another synthetic analog) at histone H3K56 using non‐canonical amino acid mutagenesis to afford a chemically modified nucleosome in lieu of their own in vivo. We further demonstrated that acetylation of histone H3K56 partly tends to provide a more favorable chromatin environment for DNA repair in yeast compared to crotonylation and crosstalk with other PTMs differently. This study provides a potentially universal approach to decipher the consequences of different histone lysine PTMs in eukaryotes.
