A real-time and accurate detection approach for bucket teeth falling off based on improved YOLOX
Authors: Lu Jinnan , Liu Yang
Published: November 2022

Abstract. An electric shovel is a bucket-equipped mining excavator widely used in open-pit mining today. The prolonged direct impact between the
bucket teeth and the ore during the mining process will cause the teeth to
loosen prematurely or even break, resulting in unplanned downtime and
productivity losses. To solve this problem, we propose a real-time and
accurate detection algorithm of bucket teeth falling off based on improved
YOLOX. Firstly, to solve the problem of poor detection effect caused by uneven illumination, the dilated convolution attention mechanism is added to
enhance the feature expression ability of the target in complex backgrounds
so as to improve the detection accuracy of the target. Secondly, considering
the high computing cost and large delay of the embedded device, the deep
separable convolution is used to replace the traditional convolution in the
feature pyramid network, and the model compression strategy is used to prune
the redundant channels in the network, reduce the model volume, and improve
the detection speed. The performance test is carried out on the
self-constructed dataset of WK-10 electric shovel. The experimental results show that, compared with the YOLOX model, the mean average precision of the
algorithm in this paper reaches 95.26 %, only 0.33 % lower, while the
detection speed is 50.8 fps, 11.9 fps higher, and the model volume is 28.42 MB,
which is reduced to 29.46 % of the original. Compared with many other
existing methods, the target detection algorithm proposed in this paper has
the advantages of higher precision, smaller model volume, and faster speed.
It can meet the requirements of real-time and accurate detection of the
bucket teeth falling off.

Published: November 2022

Abstract. Wind farm control has been a topic of research for more than two decades. It has been identified as a core component of grand challenges in wind energy science to support accelerated wind energy deployment and to transition to a clean and sustainable energy system for the 21st century. The prospect of collective control of wind turbines in an array, to increase energy extraction, reduce structural loads, improve the balance of systems, reduce operation and maintenance costs, etc. has inspired many researchers over the years to propose innovative ideas and solutions. However, practical demonstration and commercialization of some of the more advanced concepts has been limited by a wide range of challenges, which include the complex physics of turbulent flows in wind farms and the atmosphere, uncertainties related to predicting structural load and failure statistics, and the highly multi-disciplinary nature of the overall design optimization problem, among others. In the current work, we aim at providing a comprehensive overview of the state of the art and outstanding challenges, thus identifying the key research areas that could further enable commercial uptake and success of wind farm control solutions. To this end, we have structured the discussion on challenges and opportunities into four main areas: (1) insight in control flow physics, (2) algorithms and AI, (3) validation and industry implementation, and (4) integrating control with system design (co-design).
Reliefs: Biographical ekphrasis and the Queer artist
Authors:   , Bruinstroop Jarad
Published: November 2022

Situated in the field of creative writing, this project identifies and conceptualises biographical ekphrasis: an emergent subgenre of ekphrasis in which poets respond to both a work of art and to the biography of the artist who created it. This thesis comprises an exegesis, which interrogates the complex relationships between artwork, artist, poet, and audience, and a collection of poems, Reliefs, which won the Thomas Shapcott Prize. Through practice-led research, this project elucidates both biographical ekphrasis’s unique amalgam of fact and fiction and its particular temporal complexities, and reveals a mode capable of a capacious and protean reckoning with history.
Implementing Wet Services in Montréal for Highly Vulnerable People Experiencing Homelessness who Use Alcohol
Authors: Poliquin Hélène , Toussaint Pierre , Flores-Aranda Jorge
Published: November 2022

Context: People experiencing homelessness and alcohol dependence are highly marginalized as they struggle to access various health and social services. This study is part of a broader feasibility study on the implementation of "wet services" in Montréal, Canada.
Methods: Four focus groups were conducted with 20 participants working in the field of homelessness. The objectives of this study were to gather their perspectives on the need for wet services in Montréal, define the main purpose of such services, and identify the key factors promoting their success.
Results: All participants felt that wet services could meet several critical needs of many people experiencing homelessness in Montréal, and most argued that they should also be implemented without delay. According to most participants, these services should be grounded in a harm reduction philosophy, take a low-threshold approach and be accessible to the target population at all times. Participants argued that wet services should primarily aim to offer a safe place to consume alcohol whilst also serving as a place where people experiencing homelessness could meet their basic needs, reconnect socially, and access various health and social services.
However, participants cited a number of financial, logistical, and organizational constraints, such as control-related mechanisms (e.g., eligibility criteria, rigid bylaws, or the institutionalization and medicalization of services), which they feared could stand in the way of achieving the objectives of wet services or perpetuate the exclusion of people experiencing homelessness. To avoid these potential problems, most participants felt that wet services should be delivered by well-established and well-funded community-based organizations, accompanied by a variety of partnership arrangements, including those with health services.
Conclusion: This qualitative study contributes to the growing body of evidence on alcohol-related harm reduction services. Its findings may serve to inform the eventual implementation of wet services in Montréal and in other locations.

Ժամանակակից հայերենի` խնդրառությամբ միարժույթ չեզոք սեռի բայերը/Univalent Intransitive Verbs with Objective Valency in Modern Armenian
Authors: Grkikyan Lala
Published: November 2022

The purpose of this article is to study the valency of intransitive verbs in Modern Armenian.
The work was carried out using descriptive, analytical, comparative and statistical methods.
Intransitive verbs of the Modern Armenian language are characterized by all manifestations of valency: subjective valency, predicative valency, valency in terms of acceptance of direct address and adverbial modifiers. Intransitive verbs representing different semantic groups are distinguished from the point of view of objective valency. Most of these verbs have objective valency. Some take object, but not by means of strong government, others do not have object valency at all. Intransitive verbs require object through both direct and indirect government. Among phrases with direct government, the most common are verbs that require an object in the dative case, which is due to the semantic diversity of the latter. From the point of view of their ability to accept the object through strong government, intransitive verbs are univalent and bivalent. The two objects that bivalent verbs require can be expressed in one case with two different cases, in another with two different prepositional constructions, and in the third case with one case form and one prepositional construction.

Published: November 2022

A new era has dawned, exemplified by the online education revolution. Because of the advent of the internet and new technology, attending a classroom is no longer the only way to study. Nowadays, you can acquire a high-quality education anytime and wherever you choose if you have internet connectivity. This paper examines students' perceptions toward the efficacy of online teaching in distance learning programs of Allama Iqbal Open University, Islamabad, Pakistan. The study falls under the descriptive paradigm. All students of the B.Ed Program in the session 2020–2021 were the population. A convenience sampling technique was applied to a sample of two hundred students. A researchers-designed instrument having fifteen statements was used in this study. The validity and reliability of the instrument were confirmed before its execution. Data were collected using an online instrument created in Google Forms. SPSS version 24 was used to analyse the data. Frequencies were used to compare quantitative data's mean, standard deviation, and percentages. The t-test was applied to find out the significant differences on the basis of students' gender. The results of the study showed that the majority of the respondents agreed regarding the efficacy and quality of online teaching in distance learning programs. The majority of the students agreed that they feel happy to attend their online classes in distance learning programs; they lose much information if they remain absent; online teaching boosts their knowledge, tutors teaching online classes and classmates support them; they can manage time to attend online classes quickly; the online environment of classes was good; their expectations of teaching and university services were excellent, and students of distance learning programs were highly motivated. Moreover, this investigation revealed that students of both genders equally agreed regarding the efficacy of online teaching in distance learning programs. This study recommended that the online tutors of distance learning programs provide more support to the students through various online activities and innovative teaching methods to enhance their learning.

The aim of the study is to analyze the amino acid composition of developed protein-free (low protein) dishes and products for children with phenylketonuria. The introduction contains the types of the disease and their description, nutritional features of this fermentopathy and possible alternative therapies, as well as the relevance of this study. The main part contains a brief analysis of the diet recommended for feeding children with phenylketonuria aged 3–6 years. The main ingredients are highlighted, and the frequency of their use in dining dishes is also determined. On the basis of the data obtained, the main shortcomings in the diets used were identified, which were taken into account in the development of new meals for children with phenylketonuria. The developed dishes include two soups, two hot dishes and one dessert. Analysis of the amino acid composition showed that the phenylalanine content in caramel-apple mousse (a portion of 150 g) is 36.85 ± 5.801 mg/1kg of product in protein bonded form and 2.715 ± 0.097 mg/1kg of product in free form; in a cream soup of baked peppers (a portion of 250 g) – 113.86 ± 5.68 mg/1kg of product in protein bonded form and 33.200 ± 0.073 mg/1kg of product in free form; in the cutlet ʻʻCarrotʼʼ (a portion of 90 g) – 290.33 ± 7.61 mg/1kg product in protein bonded form and 69.861 ± 0.202 mg/1kg product in free form; in a cream soup of zucchini (a portion of 250 g) – 264.13 ± 5.81mg/1kg product in protein-bonded form and 45.909 ± 0.763 mg/1kg product in free form; in noodles from zucchini (a portion of 150 g) – 239.59 ± 1.38 mg/1kg product in protein-bonded form and 80.334 ± 0.383 mg/1kg product in free form. In conclusion, the expediency and possibility of using the developed dishes in institutions of general secondary education is reasoned.
Chlorophyll and pheophytin: experimental aspects of corrosion regulation
Authors: Pyzhik T. N. , Povshok T. O.
Published: November 2022

The introduction indicates the object of research – natural porphyrin chlorophyll and its derivative pheophytin, as possible inhibitors of steel corrosion. Modern, reasoned data on the structure and physico-chemical properties of chlorophyll, such as aromaticity, chelate effect, amphotericity, ability to redox transformations are presented. The basic concepts are defined: porphyrin, pheophytin, aromaticity, pyrrole nitrogen, complexing ability, acidophobia, diphilicity of porphyrin and pheophytin, mass and volume corrosion indicators, corrosion inhibitor, degree of protection, inhibition coefficient. The aim of the research was to study the anticorrosive activity of chlorophyll and its derivative, pheophytin, in relation to carbon steel St3. The main part describes a method for extracting chlorophyll from the leaves of nettle dioecious (Nettle dioecious L.) and the subsequent production of feofitin from it. The methods of determining the mass and volume indicators of the corrosion rate are described. The absence of pronounced anticorrosive activity of chlorophyll in relation to carbon steel St3 in hydrochloric acid medium is shown. The effect of absorption by chlorophyll of hydrogen released at the cathode is demonstrated, which makes the use of a volumetric corrosion rate indicator vulnerable under these conditions. It was found that the pheophytin layer deposited on the metal surface exhibits an inhibition effect under conditions of acid and atmospheric corrosion. The inhibitory effect of feofitin (4,4) was established during 96 hours of exposure with subsequent damping dynamics in the experiment with 3M HCl. Under the influence of feofitn, an elongation of time was observed before the appearance of visible foci of atmospheric corrosion. Studies of the efficacy of porphyrins as corrosion inhibitors should be supplemented by the results of the long-term effects of these compounds.

“Extraire/Abîmer/Réparer”, tel pourrait être le résumé de ce que nous vivons depuis que l’Europe a entrepris au 15ème siècle son projet de colonisation du monde. Peuples, animaux, plantes, rivières, mers, rien n’a échappé à son avidité et à sa volonté de domination. Extraire, jusqu’à leurs épuisements, la force de vie et l’énergie des corps noirs et racisés, extraire du ventre des femmes noires les vies à exploiter, extraire toutes les richesses du sol et du sous-sol, abîmer les corps, la terre, les rivières et les mers, les animaux et les plantes, tout renommer, voler, piller, violer, assécher, oblitérer, voilà le programme de l’esclavagisme, du colonialisme, de l’impérialisme et du capitalisme racial. Entendons-nous bien, avidité, mise en esclavage et domination ne naissent pas avec la colonisation européenne mais cette dernière fait de la violence systémique et structurelle le fondement même de son expansion et de sa survie. Ce qu’elle offre -– désirs et plaisirs de la consommation, satisfactions narcissiques et matérielles de la domination – repose sur l’exploitation et l’extermination. “De la colonisation à la civilisation, la distance est infinie” a écrit Aimé Césaire dans son grand pamphlet poético-politique Discours sur le colonialisme (Césaire 1989: 10). La douceur de vivre pour quelques un.e.s porte la marque du sang et du fer. Réparer les dommages, atrocités, brigandages, crimes, a été, et reste, au cœur des luttes pour qu’adviennent des sociétés post-racistes, post-capitalistes, post-impéralistes et dé-patriaracalisées, dans le but d’humaniser le monde.
conceito africano de língua
Authors: Zossou Alban Aminou
Published: November 2022

Falar em língua e nas variabilidades da sua manifestação e materialização é ainda uma tarefa árdua para os pesquisadores que se dedicam aos estudos linguísticos. Juntar o conceito de cultura e de pensamento ao de língua se torna mais complicado ainda, pelo fato de que a união desses três conceitos representa um dos traços que podem caracterizar uma comunidade de língua. A primazia desse fato é que cada sociedade tem traços peculiares de caracterização. Desse modo, o propósito deste trabalho é trazer a compreensão africana do conceito de língua como expressão cultural moldada pelo pensamento social. Com isso, queremos ressaltar a importância, a sacralidade e a manifestação da língua em sociedades africanas, tomando como exemplo o grupo etnolinguístico Fon da República do Benim na África de Oeste.

Aolongodequatroanos (2016-2019), acompanhei um conjunto de famílias atingidas pela epidemia do Vírus Zika na região metropolitana doRecife. Pernambuco, depois da Bahia, foi o estado com mais nascimentos de crianças com a Síndrome Congênita do Vírus Zika, cerca de 14% do total de casos confirmados no país, quase 4.000. Ouvi diferentes explicações para a cabeça pequena, asdeficiências, a forma física com que essas crianças chegaram ao mundo. Aqui, amparada por um acervo expressivo de diários de campo e tambémpor umconjunto de revisões sobre ciência e cientistas, particularmente de matriz feminista, discutirei um quadro de multicausalidade para a cabeça diminuta dessas crianças que aciona, por exemplo, vírus, vetores e vacinas, mas sobretudo tecnociências, especialistas e o Estado. Pondero sobre alguns limites e estratégias, possíveis destinatários e o caldo crítico que as várias explicações para a microcefalia podem gerar para a Antropologia da Ciência.
Afeto e perigo
Authors: Boldrin Juliana Ramos
Published: November 2022

Neste artigo, analiso um artefato que se tornou cotidiano e que atua contendo aquilo que escapa às camadas da pele: a máscara. Para tanto, parto do quadro Os Amantes, de René Magritte, e de um relato etnográfico sobre um hospital de tratamento de tuberculose. À luz desses dois materiais, situo as tensões entre afeto e perigo geradas pelo contágio no contexto pandêmico, posicionando as máscaras como artefatos centrais para a gestão das misturas corporais. Argumento que, no contexto de pandemia, a máscara faz parte de um movimento mais amplo de proliferação de fronteiras que opera em diversas escalas, que tanto irradiam do corpo quanto nele reverberam. Compreendendo-as como parte deste movimento, foco especificamente no seu acoplamento com a respiração, atentando para a materialidade do seu funcionamento. Nesse sentido, exploro como a respiração emerge não apenas como um ponto de conexão entre nós e o mundo, mas também como um ato que faz da categoria de cuidado profícua para refletir sobre interdependência e corpo político, além de possibilitar imaginar um mundo por vir.
Rituais escolares e processos de estigmatização de estudantes
Authors: Pereira Rosilaine
Published: November 2022

Este artigo lançou como proposição, a partir de uma lacuna de pesquisa no campo de estudos sobre desigualdades educacionais, pensar os rituais escolares a partir da teoria goffmaniana de estigma (Goffman 1980), ao observar os encaminhamentos de estudantes para o conselho tutelar. A investigação foi qualitativa, com abordagem teórico-metodológica etnográfica e trabalho de campo desenvolvido durante todo o ano de 2019, em uma escola pública de ensino médio no Rio de Janeiro. Tivemos como objetivo observar os rituais de processos de estigmatização de estudantes, a partir de casos encaminhados ao Conselho Tutelar, observando como a gestão educacional lidava com os estudantes lidos como desviantes. Estamos trabalhando na interface entre antropologia e educação, e, por isso, partimos da teoria clássica antropológica dos rituais (Gennep 2013; Turner 2013) para pensarmos os rituais educacionais (Rosistolato 2015). Além disso, utilizando a teoria goffmaniana que afirma que indivíduos estigmatizados são inabilitados para uma existência social plena, considerando o contexto da escola e a possibilidade da existência de estigmas, pensamos que seja possível argumentar que indivíduos estigmatizados no lócus escolar são indivíduos inabilitados para uma vida escolar plena. Os achados desta pesquisa confirmam os processos de estigmatização de estudantes encaminhados para o Conselho Tutelar e de suas famílias, em práticas cotidianas que se consolidam de diversas formas, inclusive em processos de estigmatização dados de forma não-hermética.

This is how the modern technology is connected with the structure of capitalism. This paper is the result of analysis based on multiple studies reviewed by researcher in economics, psychology and sociology. Furthermore, this research demonstrates that how cognitive decision-making affecting profit and capital creation is shaped by the non-localized, simultaneous and intensely hi-tech connected economic activity. In short author of this paper conclude that neurocapitalism is nothing but creating capitalistic advantage by the consumption of human brain activity at the speed of light.

Published: November 2022

Pakistan and India consider sexual harassment a negation of basic rights. Both countries have ratified the CEDAW and their relevant laws on sexual harassment are aligned with the 19th ILO recommendation. Both Pakistani and Indian laws rely on committees to investigate allegations of workplace harassment and formulated strategies along with principles to deal with sexual harassment at the workplace. The Pakistani formulation of committee, legal structure, and relief clauses varies from that of Indian law. Indian law empowers inquiry committees with the supremacies of a civil court. However, Pakistani law has a distinct institution, i.e., the Office of Ombudsman, imbedded with the authority of both a civil and a high court. The Inquiry Committee does not have the powers of a civil court to exclusively determine the issue at hand. The Inquiry committee works under the laws and regulations of the department concerned. Furthermore, Indian law is silent on the imposition of a penalty, as opposed to Pakistani harassment law. Rights of appeal are guaranteed under Pakistani law, while the India Act, 2013 is silent on provisions of forums. Keeping in view studies related to harassment laws, one can say that Inquiry Committees would defeat the very purpose of the Acts of both countries. Initial inquiries by inquiry committees are mostly tainted with injustice. Implementation entails conceptual clarification, indulgent consideration, and construction of the laws by the panel of the Inquiry Committee, mostly not proficient in law. Members on panels of inquiry committees’ effect pro and cons in controversy. This partiality at their end is not addressed under both Acts, hence necessitated reforms in the enacted laws of both states.

Objective: Evidence based intervention is an effective method for improving autism spectrum disorder (ASD) in children on socialization, communication and quality of life of the parents may have an effect on the brain activity. This aim of this study is to find the effectiveness of picture exchange communication system (PECS) and parent implemented intervention (PII) among ASD children and quality of life of the parents. Methods: Sixty ASD Children who fulfilled the inclusion criteria were selected and assigned into control (n=30) and experimental (n=30) groups. Experimental group received evidence-based intervention with PECS and PII for 6 months, whereas the control group received routine care. The children were assessed for social relationship and reciprocity (SRR), speech language communication (SLC) and Quality of life of the parents before and after the intervention. For the experimental group a 3-month post intervention along with Quality of life of the parents were also assessed. Parametric and nonparametric statistical methods were used. Results: The data showed that male, nuclear family and birth order above one was more among ASD. Two-way RM ANOVA showed significant difference among groups and tests (p<0.001), and interaction of groups with tests (p<0.001). Experimental post-test-2 i.e., after 6 months showed significant improvement in SRR, SLC and Quality of life of parents compared with control group. Conclusion: The present study shows that the PECS and PII as nursing strategy can improve ASD children socialization, communication and quality of life of the parents.

Published: November 2022

Antimicrobial activity of black soldier fly larvae extract against gram-positive and gram-negative pathogenic bacteria has been discovered. Water-soluble extracts have the most potential and effectiveness as antimicrobials, with MIC values ranging from 12.5 to 25 mg/mL for both gram-positive and gram-negative bacteria. BSF larvae also create peptides called defensins and cecropins, which have antibacterial properties. Defensins were the best and most effective peptides in inhibiting bacterial growth, inhibiting both gram-positive and gram-negative bacteria (MIC value = > 29.97 µM), while cecropins were more effective on gram-negative bacteria (MIC value= 0.52 – 2.07 µM) than gram-positive bacteria (MIC value not detected).
Evaluation of Anti-Inflammatory and Wound Healing Potential of Sodium Glucose Co-Transporter2 (SGLT2) Inhibitors
Authors: R Nandhidha. , K Punnagai.
Published: November 2022

Wound healing is a very complex process involving many stages out of which inflammatory stage remains as a rate limiting phase. Most of the anti-inflammatory drugs were proven to speed up the wound healing process which is majorly achieved by migration of monocytes and neutrophils to the healing site along with leukocytes. The presence of inflammatory mediators like interleukins, TNF delay the healing process and so the drug that actively combats these mediators will prevent the prolongation of wound healing. On the other hand SGLT2 inhibitors otherwise called as Gliflozins are extensively used for their antidiabetic potential. These drugs were also proven to exhibit antihyperlipidemic, antioxidant, cardio-protective, antihypertensive activities. Considering this, Gliflozins like Canagliﬂozin, Dapagliﬂozin and Empagliﬂozin were employed to investigate their anti-inflammatory profile and their wound healing ability in vitro on VERO cell lines. Anti-inflammatory activity was investigated in vitro using protease inhibition assay at drug concentration of 200, 400, 600, 800 and 1000 𝜇g/ml. This showed that the selected Gliflozins exhibited good activity compared to that of the standard drug. Invitro cytotoxicity was determined using MTT assay on VERO cell lines and Canagliﬂozin showed a significant viability at 250𝜇g/ml compared to control. Similarly wound healing activity was determined invitro using scratch assay method. Dapagliflozin showed a significant activity of over 60% wound closure compared to the standard drug Phenytoin. Overall this work opens up a new route for exploring other medications in the SGLT2 inhibitor family for the aforementioned actions, as well as creating alternatives to the medication's principal action. This also allows for the avoidance and limitation of the use of multiple drugs for various pharmacological activities.

Factors Influencing Consumer Online Purchase Intentions of Fashion Products on the Cross-Border E-Commerce
Authors: Mohd Salim Najwa Amani , Doraisamy Logama
Published: November 2022

The cross-border e-commerce is expanding more than ever, however, despite its notable share in the e-commerce market, there is little attention on the studies of B2C cross-border e-commerce. There is also limited research that examines the factors that influence consumers to purchase on cross-border e-commerce although there is quite a number of past research that investigates consumers' intention to purchase online. On the other hand, e-commerce fashion is absolutely evolving at a fast pace. What worked two years ago may no longer be relevant due to changing consumer preferences and perceptions. Hence, it is crucial to examine the fashion market and investigate the importance of consumers’ perceived values that may influence consumers’ purchase intentions. Following this, 113 data sets from Malaysians living in Klang Valley could be obtained through online surveys. The data was then analysed to identify the relationship between the variables by using multiple linear regression via SPSS. It can be concluded that hedonic value and social value have a significant relationship with purchase intention. However, there is no significant relationship between utilitarian value and purchase intention. Global managers and marketing professionals who want to increase consumers' propensity for online shopping should consider whether their messages to consumers, the variety of products and brands offered, marketing strategies, and pricing should be more utilitarian or hedonistic in nature. Additionally, managers need to create suitable initiatives to motivate the kinds of value perceptions in consumers that will significantly boost their propensity for cross-border online shopping.
Types of reaction to pilocarpine in patients with low-tension glaucoma
Authors: Stepanova E. A. , Lebedev O. I.
Published: November 2022

PURPOSE. To determine the types of reaction to pilocarpine in patients with low-tension glaucoma (LTG) and study the nature of fluid outflow along the main pathways in different types of reaction to pilocarpine.

METHODS. The observation group included 21 people (42 eyes) with LTG aged 51 to 80 years (average age 68±9.8 years). The criteria for inclusion in the study were emmetropic refraction and no previous laser and surgical interventions on the examined eye. The anterior chamber angle corresponded to medium–wide or wide according to the classification by A.P. Nesterov. The initial stage of LTG was established in 16 eyes, developed stage — 12 eyes, advanced stage — 14 eyes.

The examination was carried out both in patients with newly diagnosed glaucoma and in patients with previously established diagnosis who received hypotensive drug therapy; in the latter case the patients were recommended to cease instillations of hypotensive drugs 10–14 days prior to the examination.

RESULTS. Among the studied LTG patients, positive pilocarpine test was registered in 5 eyes (12%), negative — in 6 eyes (14%), and paradoxical — in 31 eyes (74%).

The obtained data revealed no statistically significant differences in the initial values of anterior chamber depth, lens thickness and axial eye length between patients with paradoxical and positive reactions to pilocarpine. Therefore, there are no anatomical prerequisites for the development of a particular type of reaction to the pilocarpine test in the studied eyes.

The ease of outflow coefficient (EOC) for the drainage pathway is significantly reduced in patients with positive reaction to pilocarpine, which in absolute numbers approaches normal values. In these patients the drainage outflow reserves are preserved.

In persons with paradoxical reaction to pilocarpine, EOC for the drainage pathway is significantly reduced and is low in absolute numbers. Deterioration of the outflow along the uveoscleral pathway in pilocarpine instillations leads to elevated intraocular pressure.

CONCLUSION. The majority of patients with low-tension glaucoma have a paradoxical reaction to the pilocarpine test. The sufficiently high sensitivity of the sample allows recommending it as a diagnostic test for this type of glaucoma.

Vários medicamentos antiparasitários foram utilizados no tratamento de pacientes diagnosticados com COVID-19, mesmo sem a comprovação de sua eficácia por meio de estudos clínicos robustos. Apesar de todos os avanços atingidos desde o primeiro caso em 2020, ainda se faz necessário compreender o papel prognóstico das características clínicas dos pacientes, assim como o efeito dos tratamentos instituídos no início da pandemia sobre o desfecho da internação. Trata-se de um estudo quantitativo, transversal, observacional e correlacional que foi realizado no período de março a agosto de 2020, período identificado como primeira onda da COVID-19, em um hospital terciário, público, em Fortaleza, Ceará, no nordeste do Brasil. Foram incluídos pacientes que necessitaram de internação e avaliadas variáveis socidemográficas, clínicas e de tratamento. Este estudo evidenciou que o sintoma diarréia está associado ao desfecho do óbito, enquanto a anosmia está associada com maior chance de sobrevivência. O D-dímero acima do valor de normalidade aumentou em quatro vezes o risco de morte e foi identificado como um preditor do óbito. Dentre os medicamentos analisados, a ivermectina apresentou efeito protetor, reduzindo o risco de morte em 0,254 vezes, por outro lado, a nitazoxanida foi associada ao óbito. Assim, este estudo identificou um perfil prognóstico plausível, reforçando a necessidade premente de dados brasileiros para apropriação do cuidado sempre na direção conjunta de realocação dos subsídios dentro de um cenário público de saúde.

The results of this study revealed a steady increase in population density of leaf miners Liriomyza bryoniae  (Kaltenbach) from 1.33 larvae/leaf at the beginning of the season to 3.3, 6, and 7 larvae/leaf with the progression of the agricultural season until 10 November, a slight drop in population occurred at the end of the season. The results revealed that the leaf miner population showed a significant negative correlation (-0.74) with maximum temperature and a non-significant negative correlation with minimum temperature.  The maximum percentage of factor role was 55% for maximum temperature and ( 18 %) for the minimum temperature. Two species of insect parasitoids (Diglyphus isaea and Opius sp ) Hymenoptera order were recorded on the leafminer Liriomyza bryoniae larvae and pupae. Diglyphus isaea was the most common species. It was active throughout the growing season and increased in number as the leafminer populations increased. The rate of % parasitism was 4.3  %  on 7 Aug. increased to 7.8, 12.8, 20.3, and  38.2%  on 1 Sept., 7 Sept., 7 Oct.,  and 21 Oct respectively, while the rate of % parasitism of   Opius sp ranged from  2.6% to 5.9%  from 14 Sept to  21 Oct.

Nickel oxide NPs are widely recognized as excellent photocatalysts due to their unique optical features such as bandgap energy, retention time, strong light absorption, electron-hole recombination duration, and significant negative oxidation potential of excited electrons. NiO nanoparticles were successfully created using a combination of nickel hexahydrate precursor, ethanol, and distilled water. Nickel hexahydrate NiO was employed as a nickel precursor to create nickel oxide nanoparticles (NO3).6H2O, distilled water, and stirring until solution homogeneity were used to make alkaline sodium hydroxide, and the alkaline solution was distilled into a homogenous solution on a magnetic stirrer at 75 °C. A thick green solution was produced at pH=12.The surface morphology and nanoparticle size of the as-prepared NiO nanoparticles were estimated using SEM and AFM images of spherical NiO particles with sizes of about 26.80 nm and 37.96 nm. The cubic crystal structure of NiO was disclosed using X-ray Diffraction (XRD). NiO NP absorption spectra in the UV and visible rangesShow blue has a maximum wavelength of 341 nm. The nickel oxide band is seen at 627 in Fourier transform infrared (FTIR) spectroscopy.

Humanity has historically been affected by remarkable epidemics and pandemics, including the plague, cholera, influenza, SARS-CoV, and MERS-CoV. A novel coronavirus pandemic known as SARS-CoV-2 is rapidly sweeping the globe. Over the period, the genome of the novel coronavirus has been mutated as it passes through its primary host. The world is reporting multiple point mutations. So the objective of this study was to observe modifications in the partial region of SARS-CoV-2 for the surveillance. This cross sectional study was carried out to detect the modifications in the SARS-CoV-2. For this purpose initial screening of COVID-19 was done to collect the strain of SARS-CoV-2 using RT-PCR. Then, primers were created in order to amplify the area using the S gene of the SARS-CoV-2. The amplified product was sent for the sequencing and bioinformatic tools were used to observed the mutations and data was compared with the Wild strain of the Virus. During the analysis, one of the most important point mutation was D614G caused by the amino acid substitution of aspartic acid with the glycine. Addition to this point mutation, other important mutations have also been observed.
Acompañamiento de los grupos primarios en la enseñanza- aprendizaje durante la pandemia por COVID-19

Published: November 2022

El estudio describe el acompañamiento que tuvieron los grupos primarios en el proceso de enseñanza-aprendizaje en los estudiantes de la Universidad Católica de El Salvador durante el primer año de pandemia por Covid-19. Para ello se aplicó una encuesta a estudiantes de las cuatro facultades de la sede Santa Ana, y se entrevistó a profesionales en psicología de las unidades de Instituto Salvadoreño de Formación Profesional y la Oficina de Asesoría Psicológica y Educativa de la misma universidad.

Se encontró que el tipo de apoyo que la familia brindó a los estudiantes fue integral, porque incluyó lo económico, emocional, técnico y tiempo dedicado. En el caso de los compañeros de clase, la relación se debilitó debido a la suspensión de clases presenciales, ya que la interacción no es la misma como si se estuviera en modalidad presencial. El grupo social con menor relevancia para el estudiante durante el primer año de pandemia fueron los vecinos; en el sentido que todas las familias estaban confinadas en sus hogares y la interacción no se podía llevar a cabo.

Es necesario que, ante el escenario incierto de finalización de pandemia por Covid-19, se establezca un plan de acompañamiento psicológico al estudiante; a fin de que el proceso de enseñanza-aprendizaje se lleve de la mejor manera y así obtener uno de los frutos más esperados: graduar a un profesional integral.
