Published: August 2022

In largest population country every fifth person is adolescent in age between 10 to 19 years. As they grow with many basic issues like reproductive health problem, sexually transmitted diseases, nutritional deficiencies & mental health problems. Different problems are faced on the basis of rural or urban area. In urban area problems are more related to abuse of alcohol, less sex education, inferiority complex, exam or education stress, social relationship, habit forming drugs & so on. In this sensitive age, they get stuck unintentionally in chaos where they find harsh & difficulties. In addition, binge watching is highly trendy in all age group & it was found greater in the lockdown. Every single person indulges in binge watching for their own reason & entertainment. Firstly, no research was done on adolescent in terms of binge watching. As we are well versed this time every teenager using cell phone & electronic device. Most probably their decision making can be stumble that how to use in appropriate way, what to watch, read & listen, play game and etc. The purpose of the research is to find out binge watching among adolescent & to find out correlation between binge watching & loneliness. A mass of sample is 60 where 30 were boys & 30 were girls respectively. A purposive sampling was used & age criteria was 14 to 18 adolescents. Here independent variable are adolescents (Boys and Girls) & dependent variables are binge watching & loneliness. The two questionnaires were used a self-made questionnaire for binge watching & Loneliness Scale (Social relationship, Interpersonal relationship, Distreved reaction, social isolation, Emptiness) by Adnan Hamid & Mohammad Parvez. A descriptive statistical analysis was done for the result. The research has shown significant correlation between binge watching & loneliness among adolescents.

Published: August 2022

Forecasts of elements that can lower unemployment are always significant since they demonstrate a country's economic development strategy's efficacy. The difficulties that workers have in finding work has major implications for Vietnam's socioeconomic development. The goal of this study is to look at the influence of transportation infrastructure on unemployment in Vietnam's 63 regions from 2000 to 2020. Improvements in Vietnam's transportation infrastructure have helped cut unemployment throughout the country's 63 provinces and regions, according to the baseline regression results. When the System Generalized Method of Moment estimator was utilized in this investigation, the same results were achieved. The results of the robustness check are comparable to those of the previous tests. The Vietnamese government continues to push the development of high-quality transportation infrastructure in order to assure future socioeconomic development. This is a critical aspect in reducing unemployment and restoring the Vietnamese economy following the COVID-19 period.

Published: August 2022

This study aims to determine the effect of tax planning, deferred tax, and company size on earnings management in manufacturing companies listed on the Indonesia Stock Exchange in 2018-2020. This study is a quantitative study with secondary data from financial statements listed on the IDX and the company's official website. Sampling was done using the purposive sampling method with a sample of 40 companies for three years. The technique used is multiple linear regression analysis using SPSS software.25. The t-statistical test is known that tax planning has no significant effect on earnings management. This can be seen from the significance value of 0.238 > 0.05, meaning it is insignificant. These results illustrate that when tax planning increases or decreases, there is no significant change in earnings management. Similarly, the deferred tax variable with a significance value of 0.691 > 0.05 means that the deferred tax has no significant effect on earnings management. With these results, it can be interpreted that if the company deferred taxes, it would not make the company perform earnings management because by carrying out current earnings management, the consequence would be to increase the tax burden at the end of the period or in the following year. The company size variable with a significance value of 0.000 > 0.05 means that the size of the company has a significant effect on earnings management, so the larger the size of the company, the higher the tendency to do earnings management.

Authors: Pacheco José Antônio de Freitas
Published: August 2022

Neste breve artigo são discutidas as condições de habitabilidade de exoplanetas, em particular aquelas que afetam diretamente a existência de água líquida na superfície. O clima dos planetas depende fortemente da presença de uma atmosfera, dos gases relacionados com o efeito estufa e do ciclo do carbono-silicato, que garante a estabilidade do clima em escalas geológicas. Uma aplicação é feita ao sistema planetário presente em Gliese 667C, constituído por cinco “super-Terras”. Mostraremos que apenas Gliese 667C c apresenta condições climáticas adequadas ao desenvolvimento da vida.
AstroBioQuímica em ambientes inóspitos: estudo de hidrocarbonetos aromáticos policíclicos em galáxias ativas
Authors: Sales Dinalva Aires , Canelo Carla M.
Published: August 2022

Galáxias ativas (AGN) são aquelas em que buracos negros supermassivos (SMBHs) em seus núcleos estão capturando matéria através de um disco de acreção. Dentro do paradigma dos AGNs, um ponto ainda em debate é o do surgimento dessa atividade, desde qual o mecanismo que a provoca até como isso afeta a poeira e as moléculas nas galáxias. Para avançar nossos conhecimentos nesta questão, é preciso a realização de estudos sobre a origem e a alimentação dos SMBHs em AGNs através das emissões moleculares em galáxias, como em galáxias Megamaser de hidroxila (OHMGs), Seyfert e Starburst. Este trabalho mostra que, em AGNs, moléculas orgânicas de hidrocarbonetos policíclicos aromáticos (PAHs) são maiores (> 180 átomos de carbono) do que em galáxias com região de formação estelar. Este fato implica que PAHs sobrevivem às intensas radiações e evoluem ao longo da evolução do Universo, em que vão crescendo e incorporando nitrogênios. Esses heterociclos policíclicos aromáticos nitrogenados (PANHs), que podem variar a emissão da banda de PAH em 6.2 micrômetros, podem fornecer o elo perdido entre a bioquímica dos PAHs, vistos no gás e poeira das galáxias, e as nucleobases que constituem o maquinário codificador da vida na Terra.

Authors: Pacheco Eduardo Janot , Fonseca Vitória Bellecerie
Published: August 2022

Os voos espaciais realizados nas décadas 80-2000 trouxeram imensos progressos em nossos conhecimentos sobre as condições físicas e químicas existentes nas grandes luas dos planetas gigantes gasosos do Sistema Solar. Sobrevoos próximos sobretudo de Titan, Europa e Enceladus revelaram características surpreendentes sobre essas luas e permitiram compor um quadro bastante detalhado de suas superfícies e interiores e da atmosfera, no caso de Titan. A descoberta de oceanos interiores em praticamente todas as grandes luas de Saturno e Júpiter abriu a extraordinária perspectiva de poder existir vida extremófila nesses locais, algo desconhecido antes. Neste artigo, apresentamos características, sobretudo sobre essas três luas, e argumentos que defendem essa tese: uma nova zona de habitabilidade parece existir nos satélites rochosos de exoplanetas gigantes gasosos, multiplicando a possibilidade de existir vida extremófila através da Via Láctea.
Impacto da atividade das estrelas na habitabilidade de exoplanetas
Authors: Valio Adriana
Published: August 2022

O Sol e as estrelas apresentam atividade magnética na forma de manchas escuras em sua superfície, além de produzirem explosões e ejeções de massa de suas atmosferas. As assinaturas de manchas escuras na superfície das estrelas podem ser modeladas a fim de caraterizar seus tamanhos e temperaturas. Estrelas jovens e anãs M produzem energéticas superexplosões, as quais podem impactar os planetas em órbitas, principalmente os que estiverem bem próximos da sua estrela hospedeira. O fluxo de radiação ultravioleta destas explosões pode ser prejudicial para possíveis organismos vivos na superfície de exoplanetas orbitando na zona habitável de estrelas ativas. Entretanto, uma atmosfera com ozônio poderia protegê-los, ou então um oceano. Os ventos estelares também afetam as atmosferas planetárias, podendo ser responsáveis pela sua erosão.

The notice and action procedures in the eu and its role in internet-related disputes
Authors: Saidov Ibrokhim
Published: August 2022

Today Internet has been serving not only to exchange information, but it is a place of offering different services. Hosting service providers can be categorized as one type of online intermediaries, which provide a huge amount of information through their websites. However, they do not know which information is illegal until someone notifies them about illegal content on their website. In another word, hosting service providers should have “actual knowledge” to take action against illegal content. If they do not have actual knowledge, they should not be liable for illegal content, which they host. This article explains how notice and action procedure works in the EU and shows some main issues of its legal framework. In first section, it analyzes the different ways of interpretation of “actual knowledge” and its horizontal application to all illegal contents. Then it discusses how fast illegal contents should be removed or disabled regarding with different types of illegal contents. Finally, it recommends some future reforms to EU legislation in order to make this procedure more transparent and fair.

Source to in-house and seasonal contamination of drinking-water quality is a persistent problem in developing countries. This study was conducted in Damot Sore Woreda, Southern Ethiopia to examine physico chemical and bacteriological quality of drinking water. For this study, four Kebele administrations were selected by purposive sampling technique. Location map and water quality sampling point were prepared using Arc GIS 9.2 software. A total of 55 water samples were taken and examined for physico-chemical and bacteriological parameters;11from source,11 from household containers,11 from drinking cup,11 for dry and 11 for wet season. One way ANOVA and correlation was employed to see the statistical difference of the variables at 5% significant level and to observe associations of variables. The result of water quality revealed that average value of all selected physico chemical parameters showed variation from source to storage. But only the value of temperature decrease significantly from supplied source to household storage (p=0.036). However, other parameters showed no significant change from source to storage. Bacteriological parameters showed variation from source to household storage and from storage to point of use. The concentration of total coliform increases significantly from supplied source to point of use (p=0.024). The dry and wet season measurement showed variations in physico-chemical and bacteriological parameters. However, statistically no significant difference observed between dry and wet season in all parameters studied. The result of water quality test revealed that average values for all selected physico-chemical parameters were found within the acceptable limit of ES and WHO standards, except Temperature and Phosphate. But the result of bacteriological water quality for all sampled sites exceeded the ES and WHO standards. So, supplied water in the area is bacteriologically contaminated and therefore not suitable for domestic purposes unless treated. Keywords: water quality, source, storage, dry season, wet season.

Biogas production can be greatly affected by inoculum addition and total solids. The effect of substrate to inoculum ratios and total solids of chicken, goat and cow manure on biogas production was studied using a 0.15m3 laboratory scale batch digester at a constant temperature of 35°C. Feed stocks were mechanically minced to 3 mm effective particle sizes prior to co-digesting with untreated cow manure from a free-range dairy rearing system. Different amounts of cow substrate inoculum were used at ratios of 2:1, 3:1, 4:1, 5:1 and 6:1, while total solid levels between (7.5% and 10.5%) at intervals of 0.5% were used to study their effects on biogas production. Increasing inoculums and total solids resulted in increased biogas production with peaks at a substrate to inoculum ratio of 4:1 (20% inoculum addition) and 9% total solids. Biogas production rates of 0.61 and 0.63m3/m3d were realized respectively. Keywords: Biogas Production, Chicken-Goat-Cow Manure, Substrate to Inoculum Ratios, Total Solids

In Mexico, due to the pandemic caused by COVID 2019, most students have received remote education through public television channels and video calls via payment internet services. Although these practices can provide helpful strategies for students to continue with their school training process, the distance education modality began to demonstrate the social inequalities most students find themselves in. This situation has increased students' social and educational disparities in the South of Mexico. In that case, many indigenous communities are good examples of language education injustices before the pandemic, which has become a more critical situation during and after the pandemic. For instance, classes are only in Spanish; some indigenous teachers do not speak the language or community language variety. There has also been a lack of teachers for more than a year in different schools. Based on endangered indigenous languages experiences, in this paper, we aim to reflect on the notion of the school as a space for the democratisation of knowledge. However, in indigenous contexts, one can see critical social injustice conditions for students instead of democratisation of knowledge, as we said before. For that reason, we argue that the COVID-19 pandemic is only an issue and a minuscule particle to show the historical and structural language education injustices for indigenous people. Hitherto, it is necessary to recognise this situation all the time.

Makala hii inachunguza uhalisia wa maudhui ya usalama katika fasihi ya watoto kwa kuchanganua riwaya ya Kijana Mpelelezi (Wamitila,2007) na Usiku wa Manane (Kobia, 2010). Hadithi hizi za watoto zimejikita katika fasihi ya watoto. Madhumuni ya utafiti huu ni kubainisha masuala ya usalama yaliyodhihirishwa na waandishi wa riwaya za Usiku wa Manane (Kobia ,2010) na Kijana Mpelelezi (Wamitila,2007), kueleza jinsi wahusika watoto wanaohusishwa na maudhui ya usalama wanavyosawiriwa na kutathmini uhalisia wa maudhui yanayohusu usalama na yanayonuiwa watoto kama hadhira lengwa katika riwaya za Usiku wa Manane (Kobia,2010) na Kijana Mpelelezi (Wamitila,2007). Nadharia za uhalisia wa kijamaa na Soshiolojia ya fasihi zilitoa msingi madhubuti kuhusu mada husika. Makala hii inathibitisha kuwa masuala ya usalama yanayobainika yanafungamana na hali ilivyo katika maisha ya jamii ya karne hii ya ishirini na moja. Vita vya kikabila na ukosefu wa usalama katika jamii vinapaswa kuondolewa na kusahaulika kabisa. Hadithi za watoto za waandishi hawa zinadhihirisha uhalisia wa maudhui ya usalama. Ni dhahiri kuwa kuna haja ya kuchukua hatua za dharura kuwafahamisha watoto kuhusu umuhimu wa amani katika taifa ili wakikua wawe na uwezo wa kueneza maridhiano baina ya jamii lugha zote.

The objectives of this work were to study the change in α-amino content and antioxidant activity of whey protein hydrolysate (WPH) using gastrointestinal proteinases (pepsin and pancreatin). In addition, whey protein hydrolysate powder (WPHP) with high antioxidant activity were produced by simulated GI digestion using an in vitro pepsin - pancreatin hydrolysis for supplementation in flavored milk. Whey protein was hydrolyzed with pepsin for 2 h followed by pancreatin for 3 h. WPH was collected to determine the α-amino content and antioxidant activity. The results showed that digested WPH contained higher α-amino content and antioxidant activity than undigested whey. To study optimum temperature, WPH was dried using Spray Dryer at 130, 140, and 150 °C. Results showed that WPHP at 150 °C exhibited the highest antioxidant activity with a major area peak of molecular weight around >12,000 - 990 Da (43.4 %) and 990 - 336 Da (23.7 %). WPHP at 150 °C was selected to supplement in Cocoa flavored sterilized milk (CFSM_WPHP). α-Amino content, antioxidant activity, and microbiological of CFSM_WPHP were investigated. CFSM_WPHP contained higher α-amino content and antioxidant activity than Control (without addition of WPHP). Total plate count, fecal coliform, and E. coli of CFSM_WPHP were under Notification of the Ministry of Public Health of Flavored milk. These results suggested that WPHP has the potential as nutritive and antioxidative supplementation for Cocoa flavored sterilized milk.

A simple hydrothermal approach was used to successfully produce nanostructured Zinc vanadate (Zn3V2O8), which was calcined at 450 ℃. The structural, optical and surface morphological features of calcined Zn3V2O8 nanoparticles were investigated using a variety of analytical techniques. The produced Zn3V2O8 nanoparticles had an orthorhombic crystalline structure, with an average crystallite size of 35.14 nm, according to the X-ray diffraction pattern (XRD). Transmission electron microscopy (TEM) analysis evaluated the spherical shaped Zn3V2O8 nanoparticles. The calcined catalyst was characterized by Fourier Transform-Infrared spectroscopy (FT-IR) analysis to analyse bonding interactions between the metal fragments within the composites. The nanoparticles obtained from hydrothermal synthesis were of size 37.2 nm, and the zeta-potential of nanoparticles was found to be −25.4 mV, indicating excellent dispersion and stability. The spectrophotometer was used to analyse the UV-Vis diffuse reflectance spectra (DRS). Cyclic voltammetry and electrochemical impedance spectroscopy were used to study the electrochemical behavior of Zn3V2O8 nanostructures. The specific capacitance value of the synthesized nanoparticles was 248.5 Fg−1. The active composite material was exploited as an electrode for the Supercapacitor application, and it revealed that synthesized Zn3V2O8 nanoparticles might lead to a possible application for future energy storage technologies.

HIGHLIGHTS

Zinc vanadate nanostructures have been prepared using easy and economical hydrothermal technique and are explored for supercapacitor application

Microgrids make it easier to integrate Renewable Energy Sources (RESs) and Energy-Storage Systems (ESSs) at the consumer level, with the intent of enhancing power quality, reliability, and efficiency. This microgrid concept at the nano grid level is championed by a low voltage DC (LVDC) grid, facilitating the direct integration of several distributed generators, storage and loads that are almost DC source/load. Since the State of Charge (SOC) of the battery is an essential parameter for building energy management systems, careful monitoring of SOC is essential. The SOC of a battery directly reflects its performance; thus, straightforward, reasonably accurate, and timely estimation of SOC protects against overcharging or discharging issues, with fewer processor requirements and computations. A novel SOC estimation method is proposed based on the literature assessment of different existing SOC estimation methods. In regions with a tropical climate, the temperature range over the year is small, and the sunshine is relatively intense and fairly even throughout the year. Also, for all practical purposes, it is a fact that the model that takes inputs at the point of use gives accurate results. Considering the 2 facts mentioned above, the current model uses a less complicated algorithm, within acceptable accuracy for the purpose and relatively user-friendly.

El futuro de la generación de energía eléctrica implica que el consumidor pueda participar de una manera activa en su producción y almacenamiento, así como en la gestión de la demanda (Yahyaou, 2018). Las tecnologías basadas en la fotoelectricidad son fundamentales en la solución del problema del cambio climático y están asociadas a la reducción de emisión de gases de efecto invernadero (Himanshu Tyagi, 2018). Los consumidores finales pueden abastecerse de forma total o parcial al generar su propia energía eléctrica (Price, 2018), a esto se conoce como generación distribuida que es un sistema cuyos niveles de voltaje pueden estar en baja, media y alta tensión (Fanghong Guo, 2018). La generación fotovoltaica en baja tensión se observa en los paneles solares colocados en los tejados de los edificios a través de los cuales se aprovecha una fuente inagotable de energía proveniente del sol (Yang, 2019).. El objetivo de la presente investigación es el de diseñar un sistema de micro generación fotovoltaica (µSFV) que opere en sincronismo con la red. La investigación es de naturaleza cuantitativa ya que permitió determinar la producción de energía generada y sus costos, y es también no experimental, descriptiva, explicativa y propositiva, estableciendo relaciones de causalidad fundamentada en fuentes secundarias. El resultado fue el diseño de una instalación fotovoltaica a la cual se le realizó un análisis económico y se determinó las emisiones de gases de efecto invernadero evitados.

El presente estudio se realizó con el objetivo de obtener información geotécnica de parte de la zona sur-este de la ciudad de Machala, y en base a tal información definir la alternativa técnica adecuada de cimentación para una edificación de tres plantas del tipo residencial. Para el procedimiento de exploración del suelo se implementó la Norma Ecuatoriana de la Construcción NEC respecto a “Geotecnia y cimentaciones”, en la cual define que para una edificación de tres plantas y según las cargas de servicio es necesario analizar el suelo a una profundidad de 6m (NEC – 2015). El estudio tuvo en general una cobertura 160 Ha de superficie, se realizó en cuatro sectores: Ciudadela “San Ramón”, terreno en Avenida Colón Tinoco y Alejandro Castro Benítez, Ciudadela “García Guillen” y Lotización “Francisco Abad Vallejo”, se realizó una perforación en cada sector mencionado, formando los cuatro puntos de exploración un polígono, esto pretendiendo estimar la secuencia de los estratos de los sectores y definir una carta estratigráfica georreferenciada que sirva para prever el tipo de suelo existente en determinado punto dentro del polígono analizado.

La exploración se realizó con el equipo SPT, obteniendo muestras inalteradas durante la exploración y que fueron ensayadas en laboratorio. Los resultados del estudio de suelos presentaron que bajo estas zonas el terreno sería del tipo arcilloso, limoso, arenas finas, con rango de carga admisible entre 2 a 6 Ton/m2, nivel freático entre 1 a 2 m respecto al nivel del suelo natural. Por lo cual, fue necesario mejorar el suelo de soporte y para la cimentación se eligió definitivamente un sistema ortogonal de vigas de cimentación con zapatas de un metro.
