Authors: SARI Onur , CİN Hülya , DAMİAN Cosmin
Published: August 2023

The aim of this study is to investigate the relationship between sport injury anxiety and career anxiety of amateur football players in Turkey. The study group of the research consists of 392 Amateur football players, 59 women and 333 men, who are actively participating in the competitions of the Turkish Football Federation in the 2021-2022 season. In this study, the “Sport Injury Anxiety Scale (SIAS)” and the “Career Anxiety Scale (CAS)” were used as data collection tools. In the study, descriptive statistical methods (percentage, frequency, mean, standard deviation), independent sample T-test, One-Way ANOVA analysis and Pearson Correlation were used to analyze the data. Depending on the findings there was a significant difference according to the being injured before and league variables in the SIAS mean scores of the participants, but there was no significant difference in the variable of family income in the SIAS mean scores of the participants. On the other hand, a statistically significant difference was found in the variables of family income and league in the CAS mean scores of the participants. And no statistically significant difference was found in the CAS mean scores of the participants according to the being injured before variable. The results of the correlation analysis showed that the mean scores of SIAS were in a significant, positive and moderate relationship with the mean scores of CAS. In conclusion, it has been revealed that as the sports injury anxiety level of amateur football players increase, their career anxiety levels also increase.

Este trabajo presenta la experiencia en el uso del comercio electrónico que se ha desarrollado en apoyo a la comercialización de productos agrícola en Costa Rica en el marco del proyecto UNAPROPYMES: Incubación/aceleración de sitios de comercio electrónico para MiPyMES costarricenses en respuesta a la pandemia de la COVID-19. En este proyecto se desarrollaron cinco prototipos de sitios para comercializar productos agrícolas: tres correspondientes a grupos organizados de pequeños productores y dos de emprendimientos agrícolas individuales. Esto se hizo con el fin de brindarles a estos productores una alternativa ante los problemas de mercadeo presentados durante la coyuntura ocasionada por la pandemia COVID-19, mediante el diseño conjunto (codiseño) de sus respectivos sitios comercio electrónico. De estos cinco prototipos (resultado de la fase de incubación), solo tres han podido ser puestos en operación (logrados en la etapa de aceleración); sin embargo, uno de ellos tuvo que ser desactivado por solicitud de la organización a su cargo. Con base en la experiencia obtenida se presentan recomendaciones para el desarrollo de sitios de comercio electrónico para organizaciones agrícolas en Costa Rica.

Published: August 2023

A series of polymeric surfactants based on monodehydroabietyl polyoxyethylene(5) ether (DHA(EO)5H) and hydroxyethyl chitosan (HEC) were prepared through a three-step process. First, DHA(EO)5H was oxidized using activated MnO2 and transformed into dehydroabietyl polyethylene glycol(5) aldehyde (DHA(EO)4CH2CHO). Then, the DHA(EO)4CH2CHO was reacted with HEC and converted into Schiff-base. Finally, the polymeric surfactant, DHA(EO)4CH2CHO modified HEC (DHA(EO)4CH2CHO-m-HEC), was obtained by reducing the Schiff-base with sodium borohydride. The grafting degree (DG) of DHA(EO)4CH2CHO substitution onto HEC for DHA(EO)4CH2CHO-m-HECs was determined using elemental analysis (EA), and the surface activities and foam performance of DHA(EO)4CH2CHO-m-HECs in aqueous solution were investigated respectively. The emulsifying capacities of DHA(EO)4CH2CHO-m-HECs were evaluated according to the stability times of emulsion composed of water and liquid paraffin. The experimental results showed the DG could have significant influence on the critical micelle concentration (cmc) of DHA(EO)4CH2CHO-m-HECs and their surface tensions at cmc (γcmc), but nearly no effect on their minimum surface tensions (γmin) in aqueous solution. Among the synthetic polymeric surfactants in this investigation, DHA(EO)4CH2CHO-m-HEC with DG of 56.95% exhibited the best emulsification and foam properties.

Authors: Ebner David Hans , Gryc Vladimír , Barbu Marius-Catalin , Čermák Petr
Published: August 2023

Silver fir (Abies alba L.) wood samples were charred on one surface using an enhanced version of the traditional Japanese Yakisugi method. The 15 charred boards obtained from five charring chimneys were divided into three different zones and investigated for their physical properties. The density profile, water absorption after 24 h of water submersion, and Brinell hardness were analyzed. In general, the temperature-time regime, which causes inside surface carbonization, was more evident at the bottom than at the top of the chimney. The density profile of the specimens revealed that the surface charring treatment decreased the surface density of the wood significantly. A gradient was visible from 383 kg/m² at the bottom to 424 kg/m² at the top. Water absorption measurements showed that a thicker carbonized layer could take up more water as a result of increased porosity. While 3,684 g/m² were absorbed at the bottom, the top accounted for only 2,533 g/m². Furthermore, with increasing thickness of the charred layer, the hardness gradually decreased. The average of the charred specimens reached only 3.2% of the hardness of the uncharred back side of the specimens.

Published: August 2023

Enzyme immobilization is a useful tool to produce biocatalysts with improved performance, such as high activity, high stability at operational conditions, and easy recovery and reuse. In this context, the production of second-generation ethanol using immobilized enzymes was reviewed. Emphasis was placed on the pre-treatment and/or hydrolysis steps to increase efficiency and reduce the cost of the process. In addition, the process design of bioethanol using immobilized enzymes was critically reviewed. In the enzymatic pre-treatment, laccases, manganese peroxidases, lignin peroxidases, and lytic polysaccharide monooxygenases are the main enzymes involved. When considering processes with heterogeneous biocatalysts, laccases are the most explored enzyme. In the hydrolysis step, cellulases and hemicellulases or a mixture of them are the main enzymes explored in the literature frequently using magnetic nanoparticles as support for enzyme immobilization. Although enzyme immobilization is a mature technology, the use of these biocatalysts is frequently limited to only one step of the bioethanol production process, such as pre-treatment or hydrolysis performed using Benchmark Technology. However, some recent papers have explored innovative design processes using a mixture of immobilized enzymes or co-immobilized enzymes to join some process steps, thereby decreasing the cost of enzymes and equipment.

Published: August 2023

Rubella vaccine is usually given in combination with measles and mumps vaccines as a measles-mumps-rubella vaccination. Because it contains live attenuated virus, its use is contraindicated during pregnancy. However, since the introduction of rubella vaccine, no cases of congenital rubella syndrome have been reported following vaccination during pregnancy. We report a case of a female infant, born to a woman inadvertently vaccinated with measles-mumps-rubella vaccination early in pregnancy, who manifested a phenotype of cardiac and neurologic defects, neurodevelopmental delay, and lymphocytopenia consistent with congenital rubella syndrome.

Published: August 2023

ABSTRACT Understanding weed emergence and development aspects is essential in decision-making for management strategies. The study evaluated the effects of different sowing depths and light intensities on the emergence and development of the weeds Sida rhombifolia and Senna obtusifolia under field conditions. Each species constituted an experiment, and the experimental design used was completely randomized, with four replications. The treatments were arranged in a 6 x 4 factorial scheme, with the first factor corresponding to the six sowing depths (0.5; 1.0; 2.0; 4.0; 8.0, and 12.0 cm) and the second at four light intensities (100%, 70%, 50%, and 30% of sunlight). The seedling emergence was evaluated daily to obtain the emergence and emergence speed index. The height, time to floral induction, and dry matter of plants at flowering were also evaluated. When submitted to different levels of shading, S. rhombifolia seedlings emerge up to 12.0 cm deep. S. obtusifolia seedlings emerge at all sowing depths, even when subjected to different solar radiation intensities. Seedlings of S. rhombifolia and S. obtusifolia emerge less and slower in sowings between 8.0 and 12.0 cm depth and develop better under full sunlight in sowings between 1.0 and 4.0 cm depth. Therefore, greater depths delay the development of both species, which is important information for managing these weeds.

Published: August 2023

ABSTRACT Late blight (Phytophthora infestans) is a serious problem in potato crops in southern Brazil due to favorable climatic conditions for the development of the pathogen and the lack of resistant cultivars available in the market. Thus, this study aimed to evaluate the reaction of eight cultivars (Asterix, Catucha, BRS Clara, BRS F63 - Camila, Cristal, BRS F183 - Potira, Markies, and BRS Pérola) and five advanced clones (F05-11-03, F21-07-09, Odone 80-02, F50-08-01, and F63-10-07) to late bight under field conditions. The Agata and the clone CIP392.617-54 were used as susceptible and resistant controls, respectively. The experiments were conducted in the municipality of Pelotas, RS, in the autumn season of 2018 and 2019. Sixty days after planting, the plants were inoculated with the pathogen; and, after one week, the genotypes were evaluated for disease severity and the area under the disease progress curve. ‘Catucha’ was classified as resistant to moderately resistant to P. infestans; ‘Cristal,’ F50-08-01 and ‘BRS Perola’, moderately susceptible to resistant; and ‘BRS F63’ - Camila, F63-10-07, F05-11-03, Asterix, F21-07-09, BRS F183 - Potira, and Odone 80-02, moderately susceptible to susceptible. BRS Clara and Markies showed the greatest variations in both experiments, showing to be susceptible in the autumn of 2018 experiment and moderately resistant in the autumn of 2019 experiment.

ABSTRACT Aiming at the search for a new alternative for the sustainability of the properties in the irrigated areas of the Brazilian Northeast, the objective of this study was to identify the ideal irrigation system and depth for a better yield and quality of pear fruits in the Sub-middle São Francisco region. The experiment was conducted in the commercial orchard of the Frutos do Sol farm, located in the municipality of Petrolina, PE, Brazil, from October 2016 to November 2017. The treatments consisted of four irrigation depths (60; 80; 100 and 120% of crop evapotranspiration - ETc), under two irrigation systems (drip and micro-sprinkler), in two crop cycles of ‘Triunfo’ pear. Yield, average fruit weight, water productivity, pulp firmness and titratable acidity, total soluble solids and lightness of the fruits were analyzed. Irrigation depths of 96.04% and 94.84% ETc promote, respectively, the highest marketable yields for the first (43.48 t ha-1) and second (26.55 t ha-1) cycle of ‘Triunfo’ pear in the Brazilian semi-arid region. Drip irrigation system in the warmer period promotes higher yield. The cultivation of ‘Triunfo’ pear irrigated by drip and micro-sprinkler promotes fruits with good commercial quality in the Brazilian semi-arid region.

Published: August 2023

ABSTRACT Fresh corn is a highly appreciated vegetable in Brazil; this crop has high added value and profitability when compared to dry corn. Despite the consumer market demand for quality, cultivars are not launched every crop season and there is a small number of cultivars available to growers. This denotes a need for breeding programs focused on generating information and genotypes that can occupy this market niche. The objective of this work was to evaluate the progress of five cycles of intrapopulation recurrent selection in half-sib progenies of fresh corn, in the southwest region of Goiás. A randomized block experimental design was used, with evaluation of 64 progenies of corn half-sib progenies and selection intensity of 30% per cycle, with three replications, in the 2011-2012, 2013-2014, 2015-2016, 2017-2018, and 2020-2021 summer crop seasons. The half-sib progenies of fresh corn exhibited genetic variability through intrapopulation recurrent selection in the different selection cycles, which is still promising for further selections after five cycles, with evaluation of 64 progenies per cycle. The base population from crossings between hybrids for tropical and temperate climates showed to be promising for increasing the genetic base of fresh corn populations, with satisfactory gains over the five cycles, presenting mean heritability between the cycles of approximately 78.9% for relative chlorophyll index, 62.2% for plant height, 75.1% for ear insertion height, 70% for ear diameter, 56.6% for ear length, 71.4% for unhusked ear yield, and 71% for marketable ear yield.

ABSTRACT Objective: The aim of this in-vivo study was to assess the salivary dehydroepiandrosterone sulphate (DHEAS) and cortisol levels, and their correlation to the Cervical Vertebrae Maturation method (CVM) in males and females at pre-pubertal, pubertal and post-pubertal growth stages. Methods: 48 patients (24 males, 24 females) who were to undergo routine orthodontic treatment were screened according to the inclusion and exclusion criteria. Then subjects were grouped according to CVM stages, using lateral cephalogram, in pre-pubertal, pubertal and post-pubertal groups. Unstimulated saliva from the selected subjects was collected. DHEAS and cortisol levels in the salivary samples were estimated by Enzyme-Linked Immunosorbent assay (ELISA). Then they were compared to Cervical Vertebrae Maturation Method stages. One-way ANOVA test followed by Tukey’s post-hoc test was used to compare the salivary DHEAS and cortisol levels between different CVM stages in males and females. Independent Student t-test was used to compare the mean salivary DHEAS and cortisol levels between different males and females in each CVM stage. Result: There was a progressive increase in salivary DHEAS and cortisol concentration as skeletal maturation progressed from CVM stages 1 and 2, CVM stages 3 and 4, reaching the highest value at CVM stages 5 and 6. Their levels were higher in males than females. Conclusion: The salivary DHEAS and cortisol levels can be useful as a potential indicator of skeletal maturation, to aid in the assessment of pubertal status.
Ninguém faz a guerra sozinho. O trabalho da memória nos encontros de ex-combatentes portugueses da guerra colonial/de libertação em Angola
Authors: Antunes Maria José Lobo
Published: August 2023

RESUMO Este artigo examina o trabalho coletivo de construção de memória nos encontros de veteranos da guerra colonial/de libertação de Angola. Partindo de observação etnográfica de reuniões anuais de uma companhia portuguesa de artilharia que combateu no país entre 1971 e 1973 e de entrevistas em profundidade com ex-combatentes, o artigo propõe um olhar etnográfico sobre a revisitação contemporânea de um passado ainda sob escrutínio. Analisam-se os encontros anuais de veteranos enquanto espaços de negociação e produção do passado, incluindo a construção de intermediação com a obra literária de António Lobo Antunes, um dos conscritos dessa unidade. Argumenta-se que essas reuniões anuais de veteranos são atos íntimos de comemoração que, baseando-se no imaginário e nas dinâmicas de proximidade familiar, na despolitização do conflito enquanto acontecimento histórico, na partilha dos aspetos solares e de narrativas experienciais, constroem uma linha invisível entre o passado e o presente.
O romance Quarup, de Antônio Callado: entre a literatura e a crise brasileira
Authors: Araujo André Francisco Berenger de
Published: August 2023

RESUMO O artigo pretende examinar a repercussão, nas páginas do Jornal do Brasil e do Correio da Manhã, do romance Quarup, publicado por Antônio Callado em 1967. A análise quer mostrar o modo pelo qual o livro foi lido como um romance que expressava a complexidade das diferentes saídas políticas em jogo durante aquele momento de crise. Nesse sentido, Quarup era lido como um romance da “crise brasileira”. Mais que isso, já naqueles anos, Quarup era percebido como um momento de inflexão e transformação das formas literárias no Brasil. Por último, pretende-se ratificar, a partir das consequências do AI-5 e da censura para as atividades do próprio Antônio Callado, como a ação da ditadura militar restringiu o debate cultural e artístico, contribuindo para limitar os horizontes da imaginação política do período.
Povoar a Cultura com a Performance da Floresta: a vida de viadoplantas e a cena transespécie
Authors: Leal Dodi , Farias Saile Moura
Published: August 2023

RESUMO O texto aborda a performance da floresta como um paradigma de povoamento cultural que rompe com as noções totalizantes de humanidade-urbanidade presentes nas hegemonias sexo-gênero coloniais. Tem-se como cerne do trabalho as figuras corporais viadoplantas e transespécies como modos vegetativos de inclinação da vida e da cena. A partir de linhas das forças do trabalho Corpoflor e da acepção corpoluz elaborada na obra TRAVED: palestra-performance em realidade virtual, o estudo articula paradigmas ético-filosóficos de povoamento da cultura, reconhecendo, assim, as florestas como entidades performativas sexualizadas e generificadas.

Abstract Objective: to analyze the consumption of healthy eating markers among adolescent students in Pelotas, Rio Grande do Sul, Brazil, in 2019. Methods: this was a cross-sectional study carried out in schools taking part in the Health at School Program. Consumption of the five markers (beans, milk, fruit, cooked vegetables and raw salads) within five days prior to the study, obtained through a self-administered questionnaire, was defined as regular. Association between demographic, socioeconomic and behavioral variables and the outcomes was analyzed using Poisson regression. Results: among the 797 respondents, 2.8% (95%CI 1.8;4.1) reported regular consumption. Beans were the most regularly consumed food (48.3%); fruit, cooked vegetables and raw salads were consumed regularly by less than 30% of the students. Doing physical activities, having breakfast and having meals with the family were associated with regular consumption of the foods assessed. Conclusion: regular consumption of healthy foods was low in this population, and was associated with behavioral factors.
OBJETIVIDADE E SUBJETIVIDADE EM FREIRE E BAUMAN: AÇÃO TRANSFORMADORA SOBRE A LÓGICA DO MERCADO DE CONSUMO
Authors: Maciel Junior Percy Fernandes , Lambach Marcelo , Niezwida Nancy Rosa Alba
Published: August 2023

Este artigo busca na análise da relação entre os conceitos de subjetividade e objetividade enquanto dimensões constitutivas das identidades dos indivíduos, compreensão sobre os efeitos da mudança no sistema de controle capitalista em sua forma atual. A argumentação está fundamenta em duas referências: o pensamento do filósofo e educador brasileiro Paulo Freire sobre sua interpretação da relação entre opressor e oprimido como condicionante da dialética entre subjetividade e objetividade, e o pensamento do sociólogo polonês Zygmunt Bauman sobre as formas com as quais o sistema capitalista se apropria dos meios tecnológicos de produção e consumo para atualizar a estrutura social de controle que garante a manutenção de sua contradição essencial, a saber, de que a busca pela maximização do acúmulo de valor diminui cada vez mais sua própria fonte de geração, o trabalho abstrato. Por terem em comum, como uma de suas principais referências teóricas, o materialismo histórico-dialético do filósofo e sociólogo alemão Karl Marx, foi possível identificar na dialética freiriana e na ambivalência baumaniana, elementos de consenso que poderiam sustentar uma proposta de ação pedagógica para o desenvolvimento da reflexão crítica associada à ação transformadora, enquanto possibilidade de resgate da subjetividade cooptada pela lógica do mercado de consumo.

O ensino de Biologia nas escolas é muito importante na formação dos estudantes, pois contribui para o desenvolvimento de uma compreensão sólida e abrangente dos seres vivos e dos processos biológicos que ocorrem no mundo natural. A importância da Biologia pode ser destacada em três aspectos principais: conhecimento científico, motivação dos estudantes e aulas práticas. Considerando esses aspectos, o objetivo deste estudo foi avaliar os efeitos da utilização de microscopia digital e de pranchas impressas nas aulas de Biologia, para alunos de ensino médio, em relação à motivação e à aprendizagem imediata. A metodologia envolveu uma aula teórica sobre o tema escolhido que foi HPV e câncer de colo de útero seguida de aulas práticas com o uso de imagens de microscopia digital e de pranchas impressas. Os estudantes responderam a testes e a um questionário que avaliaram aprendizagem e motivação após as intervenções. O estudo permitiu verificar que a motivação dos estudantes é maior quando se tem uma parte prática. Já o uso de imagens de microscópios para relacionar o conteúdo, a microscopia digital e as lâminas impressas causam uma motivação elevada nos estudantes, não apresentando diferenças significativas e a importância do desenvolvimento de ferramentas inovadoras e facilitadoras no ensino de Ciências Biológicas. Dessa forma, conclui-se que a microscopia, em ambas as formas utilizadas no experimento é um fator motivador e de custo favorável, cabendo a escola optar pelo uso das pranchas impressas ou microscopia digital, considerando a sua realidade.

Parental Vaccine Hesitancy in a COVID-19 World: A Qualitative Study of Midwestern Parents’ Decisions Regarding COVID-19 Vaccination for Their Children
Authors: Beatty Simon , Macke Jamison , Griffin Kellie , Villwock Jennifer
Published: August 2023

Introduction. With the launch of the SARS-CoV-2 (COVID-19) vaccines, a new cohort of people exist who do not consider themselves to be totally vaccine-hesitant, but are specifically COVID-19 vaccine (CVH) parents. There is a need to learn from CVH parents, to ensure their concerns are addressed allowing them to comfortably vaccinate their children against the COVID-19 virus.
Methods. Surveys were used to identify CVH parents. Via semi-structured interviews, we assessed the attitudes of CVH parents towards COVID-19 vaccination in children. An inductive coding method was used to analyze transcripts and develop themes.
Results. Fourteen parents were interviewed. 50% (n=7) had received the COVID-19 vaccine even though they had doubts. Six reported that education about mRNA vaccine production was helpful in deciding to get vaccinated. Parents were reluctant regarding pediatric vaccination due to lack of long-term studies and concerns about adverse impact on childhood development. As opposed to public health leaders like the CDC and Dr. Fauci, personal physicians were the most trusted source of information and direct conversations with them were the most influential.
Conclusions. Doctors are the most trusted source of information regarding the COVID-19 vaccine. Personal conversations with health professionals were the most influential factors in vaccine-hesitant individuals deciding to proceed with vaccination. Rather than broad public health messaging and advertising to increase rates of vaccination, these findings indicate that training for health care professionals in how to effectively counsel COVID-19 hesitant patients may be a high-impact area of opportunity to improve adherence to vaccine recommendations.

MEDIA LAW IN THE COMMONWEALTH OF AUSTRALIA: CURRENT TRENDS IN DEVELOPMENT
Authors: БОЧАРОВА Мария Егоровна , МОНАХОВ Виктор Николаевич
Published: August 2023

In the modern era, the not at all new maxim that information rules the world is getting a new, this time “digital-platform” confirmation of its truth. With the emergence of global online platforms in the 1990s, the categories of “freedom of speech”, “freedom of mass information" and “freedom of self-expression”, while gradually changing the technological formats of their embodiment and implementation, keep their democratic essence and role in the processes of personal, public and state development unchanged.

As humankind enters its next information cycle, roughly covering the first decades of the 21st century, institutional and regulatory potential of the historically “youngest” information and communication freedom — the freedom of web-based (online) information and communication — is gradually taking shape, gaining institutional and regulatory potential. Like its antecedents (freedom of speech, press, radio and television broadcasting), it requires a certain upgrade of its social regulatory mechanisms as it “matures” and enters into the life of global, national and regional societies.

It is the context of the implementation of this kind of innovation on the example of a specific country — Australia — that determines the basic subject of this article, its main essential component. Specific and topical manifestations of this essence are analyzed by the authors of this article using examples of legal and other regulatory systems in the Australian media sphere. For example, one of the subjects of analysis is the question of how is Australia coping with the challenge of updating its social regulatory mechanisms in the media sphere. And, as a logical consequence of the former, is there any position in Australia's relevant experience that is worthy of reception in other legal and ethical orders?

Focusing on these issues the authors review some of the most interesting decisions taken by the Australian government over the past decade. The authors also analyse the current law and other regulatory mechanisms and instruments in Australia aimed at regulating the mass media public relations in this country as well as the main trends of their development. In particular, such as pioneer (Australia is a recognised pioneer in this sphere of legal regulation!) changes in the regulation of digital media platforms on the example of Google and Facebook (from October 28, 2021 — Meta Platforms, Inc. in Russia, admitted as extremist organization by the Moscow Tverskoi Court), and quite specific modifications of Australian national defamation law.

GREEN PHOTOCURABLE PHOSPHORUS CONTAINING COATINGS ON COTTON FABRICS
Authors: YILDIZ Zehra
Published: August 2023

In this work, a bio-based, lightweight, coated cotton fabric by using a cleaner manufacturing method, “photocuring” was proposed in order to be used as an alternative to the conventional heat-, solvent-, and water-based outdoor textile (tarpaulin, tent, etc.) manufacturing. For this purpose, photocurable bio-based phosphorylated oligomer was synthesized with the reaction between a monomethacrylate functional phosphorus containing monomer and epoxidized soybean oil (ESBO). The synthesized phosphorylated ESBO (P-ESBO) oligomer was used in cotton fabric coatings in different proportions and photocured with UV light exposure. The effects of the amount of P-ESBO oligomer in the formulation on the crystalline morphology, mechanical, thermal, surface wettability, flammability, and abrasion resistance properties of the cotton fabrics were all searched. It was revealed that the increasing amount of P-ESBO oligomer in the formulation increases the drapeability and tensile strength of the fabrics with enhanced flame resist property by giving higher char yields. Besides, phosphorylated oligomer also acted as an adhesion promoter between the fabric surface and coating layer resulting a better abrasion resistance property.

Published: August 2023

The bearing is very essential component in any mechanism. It is always running under high speed and high load conations. Failures in bearings often results in lengthy industrial downtime that has economic consequences. Prompt diagnostics of bearings failure is essential not only for the safe operation of machines, but also for the reduction of maintenance cost of any machine.

Different methods are used for detection and diagnosis of defects of bearings; they may be broadly classified as vibration and acoustic measurements, temperature measurements and wear debris analysis. The most fundamental tool for bearing diagnosis is vibration analysis. The strength and weakness of vibration represents the location of defects.

This paper discuss about the bearing failure diagnosis using vibration analysis. Crest factor is defined as the ratio of the peak value of a waveform to its RMS value. Comparative analysis is made between damaged and healthy Rolling and Ball bearings.FFT analyzer and accelerometer is use to perform experimental measurements in axial and radial directions

Published: August 2023

Concentrating solar technologies can be used for power generation as well as industrial process heating. A point focusing solar collector forms a flux distribution on the receiver plate in two dimensions at the focal plane. A tool or method for analyzing the flux distribution nature can be great helpful to know the optical quality of the receiver. Experiments needs to be carried out in the focal region of the concentrating collector to know the flux distribution on the receiver plate. Behavior of the flux distribution are measured by flux mapping techniques and also these methods can provide accurate results, but the equipment of this method is specialized and costly. A simple method need to estimate the optical quality like flux distribution and focus size for central receiver system. Thermocouple method is used for finding the distribution of flux density on the receiver. This information is helpful in the design of the receiver size, shape and the choice of the material.

BACKGROUND: Today, epilepsy is one of the most frequently diagnosed neurological diseases. Despite more than several centuries of research on epileptogenesis and the development of treatment protocols, the neurobiological basis of the disease remains poorly understood. It is reliably known that patients with epilepsy are found to have a reduced number of hippocampal neurons and gliosis: mesial temporal sclerosis (hippocampal sclerosis), but the causal relationship with seizures has not yet been established. It is of particular interest to evaluate the survival of hippocampal neurons against the background of acute epileptic seizures, which will allow to determine the mechanisms of degenerative changes in nervous tissue.
AIM: The aim of the study was to immunohistochemically assess the levels of NeuN and caspase-8 in the hippocampus during acute epileptic seizures.
MATERIALS AND METHODS: Male mice of the CBA population were used as models. The animals were divided into groups: 1st (n = 28) simulated acute epileptic seizure by intraperitoneal injection of pentyltetrazole, 2nd (n = 20) control. Histological and immunohistochemical studies were performed on hippocampal fragments, regions: CA1, CA3 and dentate gyrus.
RESULTS: Generalized epileptic seizures were noted in all animals of Group I. The weakest labeling of hippocampal pyramidal neurons with NeuN (light nuclei) was observed in CA3 region, which was observed 24 hours after pentyltetrazole injection. The same immunophenotypic pattern was observed in the CA3 region during reaction with caspase-8, which demonstrated an increase in the number of immunopositive hippocampal pyramidal neurons 24 hours after pentyltetrazole injection.
CONCLUSIONS: After a single injection of pentyltetrazole at a dose of 45 g/kg, immunohistochemical evaluation of the distribution of NeuN- and caspase-8-positive pyramidal neurons of the hippocampus revealed: a decrease in the NeuN-positive neurons and an increase in caspase-8-positive neurons one day after the seizure with subsequent recovery of the studied markers by day 5.
NeuN-immunopositive cells in subfornical organ of spontaneously hypertensive rats
Authors: Razenkova Valeriia A.
Published: August 2023

BACKGROUND: Hypertension is one of the predominant risk factors for the development of several cardiovascular and central nervous system diseases. It is important to investigate the hypertensive effects on the tissue of brain areas, lacking blood-brain barrier, such as the subfornical organ, as they provide the CNS response to stress and damage.
AIM: The aim of the research was to study the localization and functional status of the neuronal cell population within the subfornical organ of Spontaneously Hypertensive Rats.
MATERIALS AND METHODS: The study was carried out on paraffin sections of the brain of Spontaneously Hypertensive Rats and Wistar rats (n = 12). Mouse monoclonal antibodies against NeuN were used for the light microscopy. Images were analyzed by the Fiji software.
RESULTS: It was demonstrated that the spatial neuron distribution of the subfornical organ of Wistar and SHR rats is different. NeuN-positive cells of the subfornical organ of Wistar rats demonstrated dense distribution. On the contrary, subfornical organ neurons of SHRs tended to form separate groups. That observation was additionally confirmed by cluster analysis. Between the groups of NeuN-positive cells. Histochemical counterstain revealed that the gaps between neuronal groups are composed of glial cells.
CONCLUSIONS: The study showed neurons in the subfornical organ of spontaneously hypertensive rats may undergo reorganization, which is, apparently, caused by the neuronal cell death and gliosis.

Chronic granulomatous invasive fungal sinusitis (CGIFS) is a rare manifestation of the heterogeneous disease process of fungal rhinosinusitis that is traditionally managed with some form of resective or debulking surgery. Historically, these were invasive transfacial resections. With the development of endoscopic surgery this treatment has become less invasive, but surgery still forms a major component of management. It is a rare disease that usually only occurs in dry subtropical areas. We describe the case of a female in her 30’s who presented with progressive headache and facial paresthesia. Workup demonstrated a large destructive lesion centred on the left sphenoid sinus invading the orbit and middle cranial fossa. The patient underwent urgent biopsies with a presumed diagnosis of an invasive malignancy. Upon identifying fungal organisms on culture the patient was commenced on anti-fungal treatment. We describe the first medically managed case of CGIFS with orbital and intracranial extension and perform a review of the contemporary literature to better understand this rare and challenging condition.
The conundrum of acute onset midline neck swellings: a unique case report of a thyroid abscess
Authors: Shetti Preeti , Vasudevan Chenchulakshmi , Amin Dhawal
Published: August 2023

The conditions of the thyroid gland are the most common causes for midline neck swellings and present with a spectrum of clinical features and differential diagnosis, some more fatal than the others. One such rare yet worrisome condition is suppurative thyroiditis progressing to an abscess. A 17 year old male presented with an acute neck swelling with fever, pain, and hoarseness of voice. Investigations revealed leucocytosis with normal thyroid hormone levels. Contrast enhanced CT scan of the neck showed presence of an abscess of the thyroid gland with left sided tracheal shift. Incision and drainage with antibiotic support was done leading to an uneventful recovery. The thyroid gland by virtue of its capsule, rich blood supply, and high iodine content is resistant to infection. Thyroid abscess is a rare condition with high morbidity and mortality. This condition should be a differential diagnosis in cases of acute onset midline swellings. Immediate surgical drainage of the collection with antibiotic support is the gold standard treatment of this condition.
Unusual presentation and management of a penetrating foreign body in the pyriform fossa: a case report
Authors: R. Ram Shankar , A. Shafique
Published: August 2023

Foreign body impaction in the upper aerodigestive tract is considered an emergency that necessitates extraction within 24 hours to prevent adverse events. Rigid oesophagoscopy is crucial in managing sharp, penetrating, and large foreign bodies lodged in the pharynx or at the cricopharyngeus muscle level. In this case report, a 15-year-old male patient presented with throat pain after consuming a chicken meal. He experienced dysphagia and odynophagia but no vomiting, drooling, or hematemesis. Initial video direct laryngoscopy did not reveal any foreign body, and subsequent rigid oesophagoscopy under general anaesthesia was inconclusive. However, a post-operative X-ray of the neck confirmed the presence of a foreign body. A contrast-enhanced computed tomography scan showed the foreign body penetrating the right pyriform fossa. With the assistance of a medical gastroenterologist, a flexible upper gastrointestinal endoscopy was performed, and the foreign body was successfully removed from the right pyriform fossa. Prompt endoscopic removal under conditions of minimal trauma and maximum safety is the preferred treatment approach for foreign bodies in the upper aerodigestive tract, necessitating a multidisciplinary team involving radiologists, otorhinolaryngologists, medical gastroenterologists, and anesthesiologists to develop tailored treatment plans for each patient.

Published: August 2023

Background: Melasma is a common pigmentary disorder which presents with brown coloured macules that occurs around the sun-exposed areas of the skin, particularly on the face. Many treatment modalities are present but often it is resistant to treatment. The aim of our study was to compare the therapeutic efficacy and safety of tranexamic acid administered by oral and topical route in patients of melasma.
Methods: Our study was a prospective, randomised study which consisted of 40 new melasma patients. 20 patients were given Oral Tranexamic acid 250 mg twice daily, classified as Group 1, other 20 patients were given topical Tranexamic acid (3%) twice a day (fully covering the lesion), classified as Group 2 for a period of 8 weeks and both were given broad spectrum sunscreen (SPF 50). MASI was determined before starting treatment (baseline), 4 weeks and 8 weeks. Based on the reduction in the mean MASI, the therapeutic response is graded and subjective response and adverse effects were also recorded at each visit.
Results: Mean percentage reduction in MASI scores was higher in oral (52.1%) as compared to topical (31.9%) group. In oral group, headache was the only adverse effect, however, in topical group, erythema, burning, acneiform eruptions were reported. At final assessment, fair improvement was seen in both groups.
Conclusions: Both oral as well as topical tranexamic acid were efficacious for treatment of melasma, however, of the two oral tranexamic acid was safer and provided a better proportional response.
