Authors: Sanmartin Orbe Gerardo , Mollà-Esparza Cristian , Garcia-Garcia Fran J.
Published: March 2023

La alerta sanitaria provocada por la COVID-19 ha provocado que las instituciones educativas se vean obligadas a permutar de la presencialidad hacia una metodología de enseñanza remota. Una de las herramientas utilizadas por los docentes para dar continuidad a la escolaridad de los estudiantes fue Zoom. El objetivo de este estudio fue estudiar las características y satisfacción del uso de Zoom en una muestra de 40 estudiantes ecuatorianos de octavo y noveno año de Educación General Básica para el aprendizaje de las matemáticas. Para la recogida de datos se realizó una estrategia exploratoria, empleando una metodología de encuesta y alcanzando un nivel de indagación descriptivo-relacional. Los análisis descriptivos revelaron una alta satisfacción de los estudiantes en el uso de esta plataforma. Zoom fue considerada una herramienta que aporta de manera positiva a la escolaridad: no solo al hecho de recibir la clase, sino también a comprender los contenidos y motivar al estudiantado. Los análisis inferenciales revelaron que los niños y los estudiantes más mayores manifestaron mayor interés y disfrute al momento de realizar las tareas mediadas por esta tecnología. Este estudio evidencia aportes relevantes en el ámbito educativo y, específicamente, en el proceso de enseñanza-aprendizaje a través de Zoom en contexto de pandemia.
MEDIO AMBIENTE E INCLUSIÓN SOCIAL: UNA APROXIMACIÓN TEÓRICA A LA CONSTRUCCIÓN DE “NUEVAS ECONOMÍAS”
Authors: Cabral López María Antonella , Aguilera Fernández José Manuel
Published: March 2023

Las implicancias del desarrollo han ido variando a través del tiempo, lo que condujo a que las propuestas existentes en la materia también vayan evolucionando. Partiendo de esta premisa y en consideración de la necesidad de encontrar alternativas novedosas a los modelos existentes, se plantea este trabajo. El mismo tiene como objetivo presentar el marco teórico que brinda sustento a la consideración del medio ambiente y la inclusión social como ejes centrales del desarrollo en la construcción de “nuevas economías”. Para ello, se recurrió a una metodología de tipo bibliográfica-documental, de nivel descriptivo y de tipo cualitativo. Cabe mencionar que algunos de los principales hallazgos de esta investigación fueron: la identificación de la dinámica existente en el estudio del desarrollo; el abordaje que la sostenibilidad, especialmente en lo que respecta a medio ambiente tuvo en el sistema internacional; y la taxonomía que permite contar con un marco teórico para la construcción de “nuevas economías”, a partir de la consideración de los aspectos medioambientales y sociales como endógenos y no como una externalidad del desarrollo. Asimismo, esta taxonomía permite apreciar que existe una amplia gama de teorías, las cuales pueden ser tenidas como complementarias, en la mayoría de los casos, con la búsqueda de mayor sostenibilidad.

Authors: Llovera Alvarado José Gregorio
Published: March 2023

La sociedad, dentro del transitar de desarrollo y evolución, ha creado una indexicalidad de reconfiguración continua en respuesta a sus demandas, herencia historiográfica, intereses e identidad intersubjetiva; proceso transcomplejo que no solo eclosiona una nueva realidad, sino, una neoepisteme, circunscrita al realce de las tecnologías, sus componentes y entornos digitales, cuyo sentido converge en los contextos virtuales, con ello, la producción investigativa, requiriendo competencias tutoriales, para orientar los estudios dentro de la concreción de esa cibersociedad – cibercultura, condicionantes en la reconstrucción del sentido sociocognitivo, partiendo del individuo detrás del hecho online, cuya matriz eidética, genera la verdadera esencia de la dinámica epocal. Circunstancias entrópicas que permitieron declarar como prospección, comprender las interacciones dialógicas que originan los procesos tutoriales en entornos virtuales, desde un enfoque netnográfico en la gestión del conocimiento en estudiantes de postgrado, pertenecientes a la Universidad Nacional Abierta, Centro Local Portuguesa. Su sistema referencial, está fundamentado en la antropología digital de Sherry Turkle (2004), dialógica tutorial de José Llovera (2021) y construcción social de Kenneth Gergen (2007). La visión paradigmática integra la multiexistencialidad interpretativa, articulada en la etnografía virtual. El instrumento de recopilación de información fue el guión de entrevista, cuyas unidades de análisis fueron categorizadas, estructuradas y trianguladas bajo una concepción mixta. Como hallazgo, se logró una introspección de la interacción de los tutorados en comunidades online, evidenciándose una singularidad redituable, surgiendo el estilo de pensamiento en cada sujeto investigador, al entrever su sintagma cognitivo en las intervenciones, lo cual, genera confianza en el dominio de sus capacidades, dando apertura a la autonomía constructiva.
Efficient Discrimination of Some Moss Species by Fourier Transform Infrared Spectroscopy and Chemometrics
Authors: Cao Zhen , Wang Zhenjie , Gao De , Liu Yongying , Xu Dongmei , Xu Peng
Published: March 2023

Fourier-transform infrared (FT-IR) spectroscopy with the attenuated total reflectance (ATR) technique was used to classify 14 samples (11 species) from three moss families (Mielichhoferiaceae, Bryaceae, and Mniaceae). The FT-IR spectra ranging from 4000 cm−1 to 650 cm−1 of the 14 samples were obtained. To group the spectra according to their spectral similarity in a dendrogram, cluster analysis and principal component analysis (PCA) were performed. Cluster analysis combined with PCA was used to give a rough result of classification among the moss samples. However, some species belonging to the same genus exhibited very similar chemical components and similar FT-IR spectra. Discrete wavelet transform (DWT) was used to enhance the differences among species with similar chemical components and FT-IR spectra. Three scales were selected as the feature-extracting space in the DWT domain. Results showed that FT-IR spectroscopy combined with chemometrics was suitable for a systematic research classification of bryophytes.

EPISODES OF THE PAMPHLET WAR: EXPERIENCE IN STUDYING CONSTITUTIONAL AND LEGAL PREREQUISITES INDEPENDENCE OF THE USA
Authors: Тимонин М.А.
Published: March 2023

Актуальной задачей отечественной историко-правовой науки на современном этапе ее развития является выработка нового взгляда на предысторию США. Целью работы является анализ процесса формирования конституционно-правовых предпосылок независимости США, в том числе, борьбы колонистов за неукоснительное соблюдение одного из принципов британской конституции на территории Северной Америки, выраженного лозунгом - нет налогов без представительства. Исследование позволило выявить незавершенность британского конституционного права на всех его уровнях, включая право самой метрополии и её колоний. Чем и воспользовались лидеры американских патриотов, которые к своей выгоде использовали как неустойчивость, так и неопределенность правоотношений, сложившихся между имперским центром и колониями.

An urgent task of the national historical and legal science at the present stage of its development is to develop a new look at the prehistory of the United States. The purpose of the work is to analyze the process of formation of the constitutional and legal prerequisites for the independence of the United States, including the struggle of the colonists for strict observance of one of the principles of the British Constitution in North America, expressed by the slogan - no taxes without representation. The study revealed the incompleteness of British constitutional law at all its levels, including the law of the metropolis itself and its colonies. This was what the leaders of the American patriots took advantage of, who used to their advantage both the instability and the uncertainty of the legal relations that had developed between the imperial center and the colonies.

Authors: Sijabat Jadongan , Nanda Sertika Elvi
Published: March 2023

This study aims to determine and analyze the risk of bankruptcy of pharmaceutical companies on the Indonesia Stock Exchange based on the Altman Z-Score method. This research uses a type of quantitative descriptive research using secondary data sources. The data collection technique used is a documentation technique in the form of financial reports comprising ten companies for the 2017-2021 period. The method used to analyze bankruptcy risk is the revised Altman method. Where the ratio used is in the form of company financial ratios based on Altman Z Score, namely working capital to total assets (T1), retained earnings to total assets (T2), earnings before interest and taxes to total assets (T3), market value of equity to book value of liability (T4), and sales to total assets (T5). The Altman method in this study can be calculated using the following formula: Z = 0,717 T1 + 0,847 T2 + 3,107 T3 + 0,420 T4 + 0,998 T5. The results of this study indicate that three companies are at risk of bankruptcy or are in a distress zone, namely PT Indofarma (Persero) Tbk (INAF), PT Kimia Farma Tbk (KAEF), and PT Pharos Tbk (PEHA). Besides that, there are three companies in the grey area zone, and four companies in a safe condition. For the company to avoid bankruptcy risk, the company can improve the company's financial performance by optimizing the company's assets, increasing sales volume, and reducing production costs.

Vielfalt rekrutieren: Wen rekrutiert die Polizei und wen nicht? – Öffnungsprozesse und Personalgewinnung der Polizeien in Deutschland seit den 1990er Jahren
Authors: Ellebrecht Sabrina
Published: March 2023

Der Beitrag stellt empirische Trends der Personalentwicklung der deutschen Polizeien seit den 1990er Jahren dar. Mit Blick auf Geschlecht, Immigration und Bildungsabschluss werden unterschiedliche Formen der Öffnung der Polizei skizziert. Dadurch wird angenähert, wer von den Polizeien rekrutiert wird und wer nicht. Es zeigt sich, dass Zugangshürden sowohl für Frauen als auch für Immigranten und Drittstaatenangehörige nahezu aufgehoben sind, dass sich die rechtlichen Öffnungen aber nicht in den Rekrutierungszahlen niederschlagen. Des Weiteren reflektiert der Beitrag die Erfassungsmethodik der Behörden und setzt diese abschließend in Bezug zu den Anforderungen an Gleichstellungsdaten.
Die Entwicklung des Jugendstrafrechts im europäischen und internationalen Vergleich
Authors: Dünkel Frieder
Published: March 2023

Das Jugendstrafrecht hat sich historisch gesehen im Laufe der letzten ca. 100 Jahre in verschiedenen Formen zwischen einer reinen Wohlfahrts- und einer Justizorientierung entwickelt (welfare versus justice model). Obwohl es schwierig ist, verschiedene Systeme in Bezug auf Wirkung und Effizienz zu vergleichen, ist es möglich, einige Beispiele für bewährte Entwicklungen in der Praxis und positive Gesetzesreformen zu identifizieren, indem Menschenrechtsstandards als Benchmark verwendet werden. In jüngster Zeit wurden einerseits Elemente der Restorative Justice und der Kinderrechte aufgenommen. Andererseits haben in den letzten Jahrzehnten Tendenzen eines stärker straforientierten Jugendstrafrechts zugenommen, aber der europaweit feststellbare Rückgang der Jugendkriminalitätsraten, insbesondere der Gewaltverbrechen, hat die punitive Wende gemildert oder sogar umgekehrt. Einige Länder haben sich erfolgreich gegen „straforientierte Infektionen“ gewehrt und einen starken Schwerpunkt auf Alternativen zur Bestrafung gelegt. Die Jugendstrafe ist in Deutschland, Skandinavien, der Schweiz und den Niederlanden wirklich ultima ratio geblieben. Initiativen im Bereich der Restorative Justice wurden als regelmäßige vorrangige Maßnahme eingeführt, insbesondere in Belgien, Finnland und Nordirland. Es gibt jedoch in einigen Ländern auch negative Entwicklungen, oft aufgrund fehlender finanzieller bzw. personeller Ressourcen. Eine neue Reformentwicklung in Europa und den USA ist die Ausweitung des Geltungsbereichs des Jugendstrafrechts auf junge Erwachsene bis 21 Jahre oder sogar darüber hinaus.

Understanding the Challenges of 21st Century Urbanization in Northern Nigeria’s Largest City, Kano
Authors: Faisal Koko Auwalu , Bello Muhammed , Abubakar Sadiq Muhammad
Published: March 2023

Kano, the largest city in Northern Nigeria, has experienced tremendous and unprecedented urban growth since the late 10th Century, following the emergence of the city as one of the oldest and most prominent urban centers for Trans-Saharan trade that linked Sub-Saharan Africa with North Africa, Northern Arab, and other European countries. The city’s rapid urbanization is mainly attributed to the influx of people as a result of socio-economic trading activities. However, the inability of relevant government authorities to actively respond to the city’s rapid urbanization, coupled with the demographical and spatial expansion, has contributed to the enormous contemporary challenges. Therefore, the present study examined the various challenges faced due to the tremendous urbanization in Kano city, Nigeria. The study identified the city’s challenges to include infrastructure decay, environmental pollution, problem of urban mobility and traffic congestion, unemployment, and increased crime rates. It also analyzed the implementation of several strategies and initiatives of the relevant government authorities in tackling these problems while carefully recommending further solutions aimed at addressing these contemporary challenges. This is with a view of having a cosmopolitan city that continuously attracts the inflow of populace due to its socio-economic status without jeopardizing the city’s sustainable growth.
Hybrid Obfuscation of Encryption
Authors: Al-Hakimi Asma’a , Bakar Md Sultan Abu
Published: March 2023

Obfuscation is an encryption method. It allows the programmer to reform the code for protection. Obfuscation has promising chance to change the way of coding, where the programmer has the ability to program with any language, not necessarily English. Obfuscation, Unicode, and mathematical equations have the possibility to change strings and identifiers and to hide secret algorithms and business rules. Special dictionary is used for the string obfuscation to hide the logic of the program. The hybrid obfuscation technique will be implemented into a tool that automatically converts the code. It can be can be used for games and mobile applications for protection. With obfuscation, the application still has the ability to perform sufficiently and provide the desired output without any delays in performing timing. After obfuscating the source file, reverser still has the ability to break the object file but will not be able to read or understand and when obfuscation technique is complicated, reversing leads to error where original code disappears. In this chapter, hybrid obfuscation will be presented with examples, and obfuscation table is presented as well for future use.
Lipid as a Vehicle/Carrier for Oral Drug Delivery
Authors: Desai Jagruti , Desai Tapan , Patel Ashwini
Published: March 2023

The drug administered by an oral route has to withstand a harsh environment of gastrointestinal media, absorb through intestinal epithelium and circumvent first-pass metabolism in liver before reaching portal blood circulation. Moreover, hydrophobic drug molecules offer challenges for formulation with respect to their solubility and hence bioavailability. Various approaches have been developed to overcome this barrier. One of them is the use of lipids in formulation. Incorporation of the drug in lipids can result in increased solubility, absorption and thereby enhanced bioavailability. Intestinal lymphatic route of absorption has also been explored for increasing bioavailability of hydrophobic drug moieties. In this chapter, we have discussed the pathway of lipid digestion in the human body as well as the mechanism of lipid particles upon oral administration. The various lipid formulations developed and the excipients used in the formulations have also been described. The importance of lipid chain length and the effect of food in increasing the bioavailability of drug is discussed. The lymphatic pathway of lipid carriers has also been discussed.

Auto-Tuning PID Controller Based on Genetic Algorithm
Authors: de Figueiredo Rodrigo , Toso Bruno , Schmith Jean
Published: March 2023

The PID controller is widely used in industry and its tuning is always a concern for the plant stabilization. Several methods for auto-tuning the PID have been proposed over the years, however, the relay method is the most used even though this method may determine nonideal PID gains and cause some physical stress on the plant. Here is presented a proposal for an auto-tuning PID controller based on a genetic algorithm. Genetic algorithm is a well-known method that imitates the natural selection process in order to obtain approximate solutions to optimization problems. Here, the method is presented in underdamped plants with the hypothesis that any plant can be approximated to a second-order function. From the unit step response of the system, the maximum overshoot and peak time were used in the GA evolution to obtain optimal PID parameters. The system was tested with a set of parameters and compared to MATLAB PID tuner function. Using the rising time and the settling time of unit step response from the closed loop system as validation parameters, the GA presented better results than the MATLAB tuner for most cases.

Authors: Balestra Sofía , Rios Zelmira , Palomar Nicolás , Carnevale Martín , Ferrea Mónica
Published: March 2023

Introducción: El tratamiento del tumor de fosa posterior implica la resección quirúrgica, sola o en combinación con tratamientos coadyuvantes, como la radioterapia y quimioterapia. Luego de la resección quirúrgica, el 20-30% de los niños presentan síndrome de fosa posterior. En esta serie de casos, describimos el abordaje médico y la recuperación funcional de tres niños con síndrome de fosa posterior en una clínica de rehabilitación de Buenos Aires.

Presentación del caso:  Se analizaron tres niños (dos de sexo masculino y una femenino), de entre 5 y 15 años de edad, con síndrome de fosa posterior dentro de los 30 días postquirúrgicos e internados para neurorrehabilitación entre el 2016 y 2021. Se realizaron evaluaciones, previo y posterior a la rehabilitación, de los hallazgos en los estudios de imágenes, de las manifestaciones neurológicas mediante la escala para la evaluación y calificación de la ataxia (SARA) y de la movilidad funcional mediante la escala de movilidad funcional (FMS).

Conclusión: Al alta del centro de rehabilitación, los tres niños evidenciaron mejoría en las manifestaciones neurológicas, la movilidad funcional y los hallazgos en las imágenes. Sugerimos la realización de estudios prospectivos con mayor tamaño muestral y utilizando escalas validadas.

Im Zentrum dieses kulturlinguistisch ausgerichteten sprachhistorischen Beitrags stehen Stammbucheinträge. Sie werden in das album amicorum von Personen ingetragen, die dem Albumbesitzer ihre Verbundenheit versichern und auf diese Weise die Erinnerung an die gemeinsam verbrachte Zeit in seinem Gedächtnise wachhalten können. Analysiert werden Stammbuchinskriptionen aus zwei Alben, die in der zweiten Hälfte des 18. Jahrhunderts entstehen. In beiden Dokumenten befinden sich eigenhändige Text- und Bildeinträge, die an unterschiedlichen Orten entstanden sind, wobei in beiden Fällen die Stadt Grünberg in Niederschlesien, heute Zielona Góra in Polen mehrmals dokumentiert wird.Der Untersuchungsfokus des Beitrags liegt auf Emotionen. Anhand einer Belegauswahl aus beiden Stammbüchern wird gezeigt, auf welche Art und Weise die emotionale Nähe der einzelnen Einträger nicht nur dem Stammbuchbesitzer gegenüber, sondern auch der Inskribenten zueinander zum Ausdruck kommen kann.
Farrapos de alma em palavras rasgados: a transcendência nos termos de Mia Couto
Authors: Soares Mafalda
Published: March 2023

By leaning on the analysis of passages from certain literary works by Mia Couto, the present article aims to demonstrate that transcendence is an essential characteristic of the literary process. The word “transcendence” will be understood, in this ambit, as an enquiry that spreads beyond established limits, and the writer will be presented as a figure who goes through three phases of transcendence. In the first place, the writer will overcome the a priori he has been attributing to the world, returning to a puerile attitude of wonderment. This attitude will make reality appear renewed and will unveil aspects once concealed. In the second place, the artist will feel the need to exceed the frontiers of the standard language, in order to better portray one of his empirical experiences. We will not forget to mention that language, even if stretched by the writer, is always a suggestion – and never a faithful portrait – of the singular living of each person. In the third place, the writer will end up transcending himself: not only in the sense that he will transform a piece of his existence into writing – allowing his testimony to go beyond the individual sphere in which it was generated – but also, and above all, in the sense that he will enable others to go beyond the first authorial meanings.

Microscopic evaluation of canine female reproductive tract tissues can provide a wealth of information regarding reproductive health of a bitch, including potential issues with fertility. A thorough understanding of procedures used to obtain samples, as well as microscopic anatomy of canine female reproductive tract, is important in order to understand strengths and limitations of these modalities. Appropriate evaluation of canine female reproductive tract using cytology and histopathology requires not only a solid understanding of basic microscopic structure, but also an understanding of how reproductive tract, specifically cranial vagina and endometrium, undergo striking changes during stages of estrous cycle. This review will cover microscopic endometrial structure of bitch, including a review of endometrial histology, sampling techniques, application of microscopic evaluation, and relationship of these methods to microbiome health.
Canine placental microbiome

Published: March 2023

Placenta is a pregnancy-specific organ responsible for maintenance of gestation and offspring survival in utero. Similar to other immune-privileged sites, fetoplacental unit was considered sterile. However, there is now strong evidence in humans that placenta harbors a unique microbiome. Although this work is in its infancy in veterinary medicine, there are accumulating metagenetic data to support the role of maternal reproductive tract microbiome in pregnancy success and adverse outcomes via placenta. This paper will review and highlight the emerging field of metagenetics in canine reproductive medicine. It will summarize what is known in humans, as well as veterinary species, with an emphasis on future metagenetic characterization of a canine placental microbiome and its potential role in pregnancy outcomes.

Pharmacologically induced ejaculation is utilized in stallions when traditional semen collection procedures are not appropriate or not effective. Most common protocol includes oral imipramine hydrochloride, with intravenous xylazine hydrochloride given 1 - 2 hours later. Goal was to document success rate from past clinical experience (historical data) and to determine whether addition of oxytocin along with xylazine or a prostaglandin analogue prior to xylazine treatment would enhance success rate in aged stallions in a clinical setting. Semen was successfully collected in 3 of 7 aged stallions using the standard protocol. In the modified protocol, 22 times (out of 50 attempts) semen was successfully collected from 12 stallions. However, addition of oxytocin or a prostaglandin analog had a deleterious effect on passive emission of semen.

Follicle stimulating hormone receptors (FSHR) are present in granulosa cells, Sertoli cells, and other sites within the reproductive tract (uterine tube, uterus, placenta, and cervix). They are also present in many nonreproductive tissues (skin and adipose tissue, bone and cartilage, thyroid tissue, bladder and urethra, monocytes and endothelial cells within colon, pancreas, kidney, lung, liver, and in stomach cancer tissues of various species). However, the expression of FSHR outside of the reproductive tract in sheep, has not been reported. Objective was to determine FSHR expression in ovine ovary, uterus, liver, kidney, heart, and skeletal muscle. Tissue samples were collected at slaughter and FSHR expression was determined via immunohistochemistry in formalin-fixed and paraffin-embedded tissue sections. Within the reproductive tract, FSHR were expressed in granulosa cells, luteal cells, and endometrial glandular epithelial cells. In liver, FSHR were expressed within hepatocytes and vascular endothelial cells. Expression of FSHR in cardiac myocytes was limited to cell membranes. Kidneys had FSHR expression on the renal tubular epithelial cells and the capillary endothelial cells. Lastly, in the skeletal muscle, FSHR were expressed in the endomysium. In human cancers, FSHR activation in nonreproductive tissues is involved in vascular remodeling, angiogenesis, cell proliferation, migration, and invasion. Effects of FSHR activation on ovine nonreproductive tissues remains unknown and warrants investigation into risks of frequent use of FSH agonists in sheep for nonseasonal estrous cycle manipulation.

Günümüzde şirketlerin temel amacı hem risk hem zaman faktörünü dikkate alan firma değerinin maksimizasyonunu sağlamaktır. Bu amaç şirketin hisse senetlerinin piyasa değerinin maksimize edilmesini sağlayacak şekilde kararlar alınmasını gerekli kılmaktadır. Değer maksimizasyonunun sağlanmasına etki eden en önemli faktörlerden biri sermaye yapısı diğer bir ifadeyle finansman karmasıdır. Sermaye yapısı şirketlerin varlıklarının finansmanında kullandığı kaynakların bileşimini ifade etmektedir. Varlıkların finansmanında kullanılan her bir kaynağın maliyeti düşünüldüğünde şirketler açısından optimum sermaye yapısının oluşturulması firma değeri üzerinde önemli bir etkiye sahiptir. Şirketlerin optimum sermaye yapısının tespit edilmesini sağlamak amacıyla pek çok teori geliştirilmiştir. Bu araştırmada öncelikle teorik çerçevede sermaye yapısı, sermaye maliyeti ve sermaye yapısını etkileyen faktörler ele alınmış, devamında klasik ve modern sermaye yapısı teoriler açıklanmıştır.
A Popular Dietary Supplement: Chlorella
Authors: Çil Elif
Published: March 2023

Recent research shows an inverse relationship between dietary intake of antioxidant-rich foods and the incidence of human diseases. Since synthetic antioxidant compounds are suspected to be carcinogenic, the search to replace them with natural antioxidants has become a severe action in pharmaceutical research today. In this context, microalgae are wealthy sources of pharmacologically active metabolites with antineoplastic, antitumor, and antimicrobial properties. A microalga such as Chlorella vulgaris, which has active ingredients rich in natural antioxidants in nature, gains excellent importance in this context. Previous studies have reported that C. vulgaris contains a wide variety of bioactive secondary metabolites such as flavonoids and phenolics with antioxidant activity. The first antibacterial studies on Chlorella were made in 1944 by Pratt et al. in his work. They reported that Chlorella has an antibacterial content, which they call Chlorellin. Apart from all these studies, other different effects of Chlorella, such as relieving fatigue, deactivating toxic substances by disrupting their structure, and removing heavy metals from the body, have been investigated in various studies. These properties have made using different Chlorella microalgae as a food supplement popular in recent years. The most popular foods and beverages, such as gluten-free bread and smoothies, promise low fat, high protein, and antioxidant content. In this study, studies on the biological activity of Chlorella will be compiled.

Adhesive bonding technology have been widespread in several industrial sectors owing to relevant benefits in comparison to conventional mechanical fastening methods like bolting or riveting. Bonded joints, in their varied formats, have been utilized in many industries as is the case of aeronautical, automotive, naval, wind energy, among others. Tubular adhesive joints (TAJ), although being rarely studied, have found their space and applicability in the construction, motor sports or pipeline industries. In this work it was performed a numerically study, involving cohesive zone modelling (CZM), aiming to assess the influence of geometrical changes on the performance of aluminium TAJ connected with Araldite® 2015 adhesive. The numerical axisymmetric CZM models used in this work were previous validated with experimental results. The geometrical variations for TAJ considered in this work were an outer chamfer, an inner chamfer (both in the adherends), and adding an adhesive fillet at the overlap ends. The geometrical variations analysed in this work have shown significant stress reductions although they are not reflected in an elevated increase in terms of the joint maximum strength, this is mainly due to plasticization of the aluminium adherends.

Background: Internet addiction (IA) is one of the most prevalent mental health problems among adolescents. Several studies have reported that the prevalence of IA among adolescents has increased during the COVID-19 pandemic. However, with China’s ongoing regular epidemic prevention and control, it is unclear whether the prevalence among adolescents is still at such high levels in China during the COVID-19 pandemic. Therefore, we conducted a cross-sectional study from December 2020 to January 2021 that aims to understand the prevalence and related factors of IA among adolescents in Nanchang, China, during the pandemic. Methodology: The cross-sectional survey was conducted in seven secondary schools in Nanchang. Participants completed a questionnaire comprising Young’s Diagnostic Questionnaire for internet addiction (YDQ), International Physical Activity Questionnaire Short Form, and questions regarding demographic characteristics, outdoor activity time, and sleep quality. Results: A total of 6,553 secondary school students participated in the survey. Of the total, 14.4% (946/6553) were classified as addicted internet users (YDQ ≥5). The risk of IA was higher among students of older age (OR=1.17) and with poorer subjective sleep quality (OR=1.27-2.56). Urban household registration (OR=0.80), high level of physical activity (OR=0.68), 1-2 hours of outdoor activity per day (OR=0.69), long sleep duration (OR = 0.60), and normal sleep duration (OR = 0.74) were protective factors of IA. Conclusions: During the COVID-19 pandemic, adolescents in China reported some risks for IA. Age, household registration, outdoor activity time, level of physical activity, subjective sleep quality, and sleep duration were the key factors affecting IA. Therefore, extended school and family support should be provided for vulnerable adolescents in this extraordinary period.
