Published: December 2022

Enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (SSCs) transplantation. Fetal bovine serum (FBS) is the most widely used growth supplement for cell cultures, primarily because of its high levels of growth stimulatory factors and low levels of growth inhibitory factors. This study was undertaken to investigate the effect of serum concentration on colony formation and development of different types of SSC colonies with respect to passage number. Cells were isolated from pre-pubertal buck testes by two step enzymatic digestion method. The filtered cells were enriched by differential adherence selection method. Cells were then randomly divided into 8 groups, depending on concentration of FBS in culture medium ranging from 0% to 35%. In experiment 1, effect of different concentrations of FBS on total number pSSCs with reference to differential plating was observed while in experiment 2, effect of different concentrations of FBS on types of pSSC colonies with respect to passage number was observed. No colony formation was observed in control group (0% FBS) while significantly higher number of single, paired, cluster and rosette colonies observed were with 20% FBS group in differential 2 (D2) as compared to other groups. Alkaline phosphatase staining and immunocytochemistry staining (PGP9.5 and OCT4) were positive in SSCs colonies. The growth rate of the culture was significantly and consistently higher with 20% FBS.

Published: December 2022

The aim of this study was to evaluate the changes of blood metabolomics in calves with pica, which causes serious harm to livestock. Two groups, each comprising 12 calves of approximately 3 weeks old and of similar weight were selected as subjects; Group A calves were control animals in good condition and Group B calves (pica animals) had rough hair, emaciation, flaccid forestomach, diarrhoea, and stunted development. Blood samples were collected from the tail root vein. Masslynx 4.1 software (Waters Company) was used to pre-process data, which were then analysed by principal component analysis, partial least squares discriminant analysis, and orthogonal partial least squares discriminant analysis. Twenty potential biomarkers were closely related to the occurrence of pica, viz. GDP-glucose, UDP-glucose, proline, creatine, arginine, glutamine, citrulline, urea, alanine, methionine, serine, glycerate, cysteine, spermine, spermidine, carnitine, xanthurenic acid, kynurenine, and thyroxine. Metabolic pathway analysis showed that, in calves, pica resulted in decreased antioxidant capacity; disruption of the mutual transformation between pentose and glucuronic acid; abnormal metabolism of cysteine, methionine, serine, arginine, and proline; impairment of lipid metabolism; reduced immunity; increased intestinal permeability; and elevated central nervous excitability. Calves with pica exhibit disruption of various metabolic pathways.

Published: December 2022

This study was conducted to investigate the effect of different levels of oak kernel on rumen digestibility and fermentation, blood metabolites and liver enzymes of Khuzestani buffalo. Sixteen male buffaloes, one year old were fed with experimental diets containing different levels of oak kernel (0, 15.8%, 31.58% and 47.37% equal to 0, 1.5, 3 and 4.5% tannin, respectively) in a completely randomized design for 35 days. In end of experiment, dry matter intake, digestibility, rumination behaviour, rumen and blood parameters were measured. The results showed that oak kernel increased dry matter intake and digestibility of dry matter and organic matter but the digestibility of protein, NDF and ADF was decreased. Incorporation of 47.37% oak kernel in the diet caused significant decrease in ammonia- N and protozoa population of buffalo rumen, but pH and total fatty acids were not affected. The rumination activity in diet containing 47.37% oak kernel was the lowest. With the increasing oak kernel in the buffalo diet, blood cholesterol level decreased, but there were no significant changes in blood glucose, urea, triglycerides, alkaline phosphatase, aspartate and alanin amino transferase enzymes between the experimental treatments. Therefore, even if the digestibility of ADF and CP decreased by adding of oak kernel but the using of oak kernel up to 47.37% in buffalo diet had no negative effect on the rumen fermentation characteristics, digestibility and blood metabolites, hence it may be used in buffalo’s diet.

Published: December 2022

This study evaluated the effect of flax meal (FM) and barley rootlets (BR) in Holstein dairy cows compound feeds (CFs) in order to assess their effects on the quality (physico-chemical parameters and fatty acids composition) and quantity (yield) of raw milk. The trial used a number of 15 multiparous Holstein dairy cows, at 27 weeks midlactation stage, averaging 624.19 kg of BW, with an initial average milk yield of 22.36 litres/day. The cows were divided in 3 groups (C, FM and FMBR diet, respectively), for 63 days. Cows were fed twice/day, and received a basic concentrate mix (corn, soybean meal, sunflower meal and wheat bran) and roughage (alfalfa hay and corn silage). The use of FM in dairy cows' CFs resulted significant increase of milk fatty acids (FA) and milk yield. At the end of the trial for both experimental groups (FM and FMBR), the C18: 3n3 FA was significantly higher, (0.526% and 0.522% vs. 0.23% C group of total FAMEs), representing a good source of n3. This indicates that the fatty acid addition from FM was favourable to the C18: 3n3 fatty acid in milk.

Published: December 2022

The aim of the present study was to investigate the role of silver nanoparticles (AgNano) supplementation during early embryogenesis on the post-hatch performance and immunity in broilers. Increasing concentration of AgNano 0 (un-injected control), 12.5, 25 and 50 μg/egg, respectively were administered on 7th embryonic day at the broad end of broiler egg, following in ovo feeding techniques. A total of 60 eggs per treatment were used and five replicates of 8 birds each in all treatment were reared upto 42 days post-hatching. Egg weight, chick weight and ratio were similar in all the groups, however, the hatchability decreased with increasing AgNano concentration. Average daily weight gain was increased in all the AgNano supplemented chicks. Average daily feed intake and feed conversion ratio were not affected by AgNano supplementation. Pancreas weight has shown an increasing trend with increasing concentration of AgNano. The bursa and spleen weight were increased with increasing concentration of AgNano supplementation during embryogenesis. In vivo Immune-response to phytohaemagglutinin- P and sheep RBC was increased in AgNano supplemented chicks. Serum cholesterol level was decreased in AgNano supplemented chicks unlike glucose and total protein. Early embryonic supplementation of AgNano particles modulates the post-hatch growth performance and immunity in broilers.

Expressões idiomáticas zoonímicas em dicionário inglês-inglês correspondentes tradutórios possíveis
Authors: Lima Giovana Silva , Budny Rosana
Published: December 2022

O presente artigo tem como objetivo apresentação a investigação e dar uma amostra da compilação de algumas expressões idiomáticas e coloquialismos zoonímicos a partir de um dicionário de expressões idiomáticas gerais da língua inglesa, e que, nesta pesquisa, se limita à fonte bibliográfica Dictionary of Idioms: more than 600 phrases, sayings e expressions de autoria de TERBAN, M. Scholastic (2006). Segundo Budny (2015), os coloquialismos zoonímicos ou unidades fraseológicas com zoônimos (UFz), como a autora as nomeia, são expressões metafóricas compostas de pelo menos um zoônimo e são integrantes da cultura de uma comunidade e/ou país. Esses coloquialismos expressam aspectos particulares da comunicação cotidiana. As expressões idiomáticas (doravante EIs), uma das categorias das unidades fraseológicas, por serem expressões que denotam formas coloquiais e informais de comunicação, precisam receber atenção especial durante a aprendizagem de uma nova língua, visto que expressam uso real da língua em seu cotidiano. Nadin et al (2015, pg. 53) argumenta que é possível observar a dificuldade de estrangeiros em entender o uso e o significado das EIs, com respeito ao sentido conotativo, pois esse sentido carece de contextualização social e cultural, coisa que os estrangeiros nem sempre dispõem. Esse argumento justifica o estudo das expressões populares, como forma de facilitar a aprendizagem de uma língua estrangeira. Para embasar esse campo de estudos, são citados autores da área da Fraseologia e da Lexicografia como Xatara (1998), Ortiz Alvarez (2000), Budny (2015), entre outros. Como resultado, apresentamos uma amostra do levantamento bibliográfico, e análise de alguns correspondentes tradutórios, com tradução feita com base em pesquisas em dicionários e internet.
A Educação Para as Relações Étnico Raciais Sob a Perspectiva da Interdisciplinaridade
Authors: Almeida Martins Goiz Juliana
Published: December 2022

A interdisciplinaridade enquanto reflexão e ciência contemporânea, tem como propósito viabilizar a comunicação e interação entre os diversos campos científicos, sugerindo a ruptura com a superespecialização e o esfacelamento dos conhecimentos. No início da década de 2000, foi implementada a Lei 10.639/03 que trata da obrigatoriedade do ensino de história e cultura da África e dos afro-brasileiros nos estabelecimentos de ensino públicos e privados em âmbito nacional e posteriormente determina as Diretrizes Curriculares Nacionais para a Educação das Relações Étnico Raciais e para o ensino de história e cultura afro-brasileira e africana DCNERER, temática esta que aborda de forma ampla a pluralidade cultural, já apontada nos Temas Transversais. A Educação para as Relações Étnico Raciais deve ser tratada como uma área específica do ensino ou tem potencial para ser agregada a toda grade curricular por meio da interdisciplinaridade? Para este estudo tivemos como objetivos discutir sobre como alguns autores que são referências na interdisciplinaridade caracterizam este conceito e sua contextualização histórica, analisar questões relativas a Lei 10.639/03 e a possibilidade da construção de uma educação antirracista e para finalizar, refletir sobre o tratamento da Educação para as Relações Étnico Raciais por meio de um viés interdisciplinar. Para este fim, aderimos como abordagem metodológica a pesquisa qualitativa, sistematizada na investigação de dados bibliográficos. As observações preliminares indicaram que, embora existam legislações que tratam da interdisciplinaridade e da educação para a diversidade ainda são comuns as incertezas nestes campos científicos. Consideramos que o conhecimento interdisciplinar seja uma premissa indispensável para a reflexão e reorganização dos conhecimentos e para o tratamento da diversidade.
Jornalismo e Reprodução de Estereótipos
Authors: de Oliveira Lopes Pablo
Published: December 2022

A presente pesquisa, de caráter interdisciplinar, analisa como a atividade jornalística participa da reprodução de estereótipos e de que maneira pode contribuir para a manutenção de preconceitos e convenções sociais relacionados aos homossexuais no Brasil da década de 1980. Por meio da identificação de textos e imagens voltados aos homossexuais e à AIDS, publicados no jornal O Globo, procuramos verificar a presença de estereótipos ou fatos que possam caracterizar a formação de preconceitos em relação aos sujeitos da pesquisa, no discurso jornalístico, e analisar como se dá a construção dos estereótipos, compreendendo as condições materiais e mentais em que são forjados. O jornal O Globo constitui a fonte selecionada para o desenvolvimento da pesquisa devido à influência que exerce sobre o discurso da imprensa brasileira. O Globo está entre os veículos de maior circulação no país e ocupa, portanto, posição importante na divulgação das notícias, na reprodução de estereótipos e na disseminação de preconceitos. Apesar de ser publicado no Rio de Janeiro, a penetração em outros estados brasileiros transporta a retórica de seus jornalistas para diversas regiões do território nacional. A retórica do preconceito é uma das formas de manifestação do discurso social. A linguagem é capaz de nos apresentar os papéis desempenhados pelos indivíduos em uma sociedade e pode constituir-se em uma forma de representação mental. Pode-se desenvolver um estudo com base no inventário cronológico dos vocábulos, buscando seu significado de acordo com os valores impostos pelo discurso discriminatório de quem os utiliza. O estudo do léxico pode indicar a mentalidade de uma determinada época. Sendo assim, a reflexão sobre os textos publicados no jornal impresso recairá sobre a semântica das palavras. Palavras assumem conotações distintas na dependência do contexto em que são empregadas e da ideologia de quem as usa. Noções, conceitos, comportamentos, atitudes e políticas públicas são influenciados por discursos, cujas estruturas dependem dos vocábulos usados e do que significam. Isso se aplica à disseminação de preconceitos e de estereótipos sobre determinados grupos populacionais, como é o caso dos gays. A partir dessa premissa, propõe-se a análise dos textos jornalísticos da década de 1980, considerando-se a abordagem dispensada à AIDS e aos homossexuais, naquele período histórico, a partir da desconstrução dos discursos, como sistematizado por Tucci Carneiro (1994).

Published: December 2022

Huntington's disease (HD) is a rare, autosomal dominant, progressive neurodegenerative disorder. HD manifests with a triad of progressive motor, cognitive, and psychiatric symptoms. Our patient, a 39-years-old married female with over a nine-year history of psychotic symptoms. The patient was diagnosed and treated for schizophrenia. Over the last 2-3 years, the patient had a progressive decline in her Activities of Daily Living, instrumental activities of daily living, and psychotic symptoms. She developed slurred speech, gait disturbances, frequent falls, involuntary movements of the trunk and distal extremities, bowel and bladder incontinence, and severe weight loss. Her genetic test for Huntington’s gene confirmed the diagnosis of HD. She was prescribed Olanzapine, fluoxetine, and clonazepam. Psychotic symptoms are rare in HD and usually appear well after the motor and cognitive symptoms. Our case highlights an unusual clinical presentation of HD, which can be diagnostically challenging and lead to diagnostic delays.

Design and construction of the MultiPly pavilion using cross-laminated tulipwood
Authors: Bateman Simon , Bartram Carolina
Published: December 2022

This paper describes the design, fabrication and erection of the MultiPly timber pavilion, which was made from the first cross-laminated timber (CLT) to be manufactured at volume in the UK. Fabricated from American tulipwood, it was originally displayed at London Design Festival 2018 and has since been reconfigured and exhibited at design festivals in Milan and Madrid. The pavilion comprises a 'vertical maze' of stacked boxes and staircases allowing the public to reach a height of over 9m from the ground. Designed to be completely demountable and reusable, it is intended to be an exploration of the issues surrounding timber's place in the circular economy and its use in modular construction. This paper details the development of the pavilion's concept, its analysis and design through use of both physical and computer models, the manufacture of the tulipwood CLT, and the fabrication and erection of the pavilion on a highly constrained site – all taking place within a timescale of less than seven months.

Introduction: HIV is a virus that can be caused by the Acquired Immunodeficiency Syndrome (AIDS). The HIV virus that is increasingly spreading or severe will lead to and cause AIDS. White blood cells are attacked by the HIV virus and cause damage to a person's immune system. This virus spreads rapidly and the African continent is its root and origin. No one has ever found a medicine to cure someone from this disease. A person's change from children to adults is definitely physical, attitude, and others experience changes. HIV/AIDS can arise if a person's changes are not appropriate.
Objective: Health education regarding the prevention of HIV/AIDS can help educate the students of SMKN 1 Ciamis on how to keep the spread of HIV/AIDS and avoid various HIV/AIDS viruses.
Method: Health education research is used in the HIV/AIDS risk prevention education method in the Adolescent Range. This health education was conducted with 36 students at SMKN 1 Ciamis, Ciamis Regency, with 15 respondents as respondents.
Result: Results of health education on HIV/AIDS risk prevention in adolescents at SMKN 1 Ciamis. There are still students who don't seem to understand about the spread of HIV/AIDS, even their concern for HIV/AIDS is still very porly understood. This will actually cause harm to a group of teenagers and their surroundings, for example promiscuity in adolescence, bringing negative sources to adolescents, causing the spread of HIV/AIDS.
Conclussion: Results of health education on HIV/AIDS risk prevention in adolescents at SMKN 1 Ciamis. Previously given counseling on HIV/AIDS prevention, there were students who did not understand HIV/AIDS prevention, but after being given knowledge about definition of HIV/AIDS, HIV/AIDS prevention, reason HIV/AIDS, ways of transmitting HIV/AIDS, it showed that students understood little the importance of preventing HIV/AIDS.

Application of Porous Layer Open Tubular Columns: Beyond Permanent Gases
Authors: Synovec Robert E. , Mikaliunaite Lina
Published: December 2022

Porous layer open tubular (PLOT) columns are traditionally built with particles that are adhered to the tubing walls. These columns have unique selectivity and provide a great alternative when gaseous samples need to be separated, but these columns also have been used to separate higher boiling point analytes. There are many different commercially available stationary phases of PLOT columns, including alumina-based columns, molecular sieves, and porous polymers. Alumina-based columns have an aluminum oxide stationary phase that is then deactivated with different salts. These columns have high capacity, superior loading ability, and produce symmetrical peaks. Molecular sieve columns are designed specifically for permanent gas separations because the columns have high retention. Porous polymer columns are highly hydrophobic, making them more applicable to analyzing a wider range of samples.
Valuable Techniques for Repeatable Absorbance Measurements
Authors: Guenther Derek
Published: December 2022

Spectroscopy offers a range of available techniques that can be differentiated by the use or omission of reference spectra. This differentiation means that techniques such as Raman or fluorescence typically look at raw intensity outputs, whereas techniques such as transmission or reflectance require some reference scan to calculate those relative outputs. Within the group of referenced spectral techniques, absorbance is easily one of the most common and offers much value because of the concentration dependence of Beer’s Law. However, this value is only properly captured when system components and samples are made to be repeatable, both for the reference scans and live acquisitions. This article discusses several useful techniques to establish this repeatability, including proper cuvette and probe handling, component setup, and sample considerations. By optimizing repeatability of the measurement system, the observed concentration values calculated from absorbance outputs are much more accurate and relevant to the sample being measured.

Published: December 2022

Hand line is a fishing gear commonly used by fishermen in Cilacap Regency to catch schools of mackerel fish. Hand line is a passive fishing gear. Mackerel is a fishery commodity that has high economic value. The construction of handline fishing gear is a plastic reel, fishing line, branch line, swivel and hook. The fishing line area is in the IB fishing line. Handlines are operated in areas with a depth of 10-15 meters. Cilacap fishermen generally operate handlines not to the bottom of the waters. The purpose of this study was to determine the difference in the catch of mackerel based on the difference in bait and hook size of handline fishing gear. The experimental method in this study used 2 variables, namely differences in bait and hook size with 6 repetitions. The bait used in this study was natural (live) bait and artificial (dummy) bait in the form of squid, as well as the size of the hook, namely fishing line size 4/0 with 6/0. The overall catch on the handline fishing gear operated was 17 mackerel fish. Based on the tests that have been carried out on the catch composition using the Two Way Anova SPSS 24 test, the results show that there is no significant difference (p>0.005) on the type of bait used on catching mackerel fish. Howeever there is a significant difference (p<0.05) on the hook size used on catching mackerel fish. These results indicates that hook size acts as an important role that may affect the catching quantity of mackerel fish. The research also indicates that there is no correlation between the 2 factors (type of bait and hook size) on the overall catch of mackerel fish in Cilacap Waters.

Published: December 2022

This research assessed land use change of Government and Community forests in Ganye and Jada Local Government Areas of Adamawa State. Data were collected from two selected Forests. The study utilized land use datasets to examine the spatial extent and distribution of forest cover in both areas over two decades. The data used for analysis were satellite imageries downloaded from google earth between the year 2000 and 2020. In an effort to determine the change in land cover of the study area, three different images at ten-year (10) interval were used (2000, 2010 and 2020). Student t-test was used to compare the results of land use classification. Results obtained indicated that all the land cover classes changed (either increased or decreased) in the study areas over the given study period. Findings also unveiled a significant net negative change in forest land cover class with extensive significant increase in bare- surfaces and a remarkable reduction in vegetation. Expansion in bare surfaces in Sammeri community and Kwana uku forest study sites between year 2000 and 2020 were (+514.42%) and (+261.59%) at the expense of a reduction in forested areas which were (−46.75%) and (−56.95) respectively. Additionally, results proved forest stocks or resources were being depleted by anthropogenic agents, owing to their hostile effects which included; fuel wood collectors, farmers, animal grazing, bush burning and unregulated logging of trees. The study recommends the need for the implementation of sustainable forest management practices in the two forests, with further extension to other notable reserves across the country.
DWave-Toolbox: Program untuk Analisis Gelombang Desain
Authors: Hakiki Irham Adrie
Published: December 2022

Gelombang desain adalah salah satu parameter utama dalam perancangan bangunan di lingkungan laut. Pada umumnya gelombang desain diperoleh dari hasil analisis statistik untuk menentukan kejadian ekstrim. Kehandalan model statistik ini sangat ditentukan oleh ketersediaan data. Selain itu, dari sebaran data tersebut, dapat juga diketahui kejadian dominan yang dapat mempengaruhi orientasi struktur. Akan tetapi, data gelombang yang tersedia di Indonesia sangat terbatas, sehingga pada umumnya data gelombang diperoleh dari proses peramalan berdasakan data angin dari stasiun pengamatan terdekat. Namun, banyak lokasi pekerjaan pantai yang jaraknya jauh dari stasiun yang ada sehingga dikhawatirkan data tersebut tidak representatif. Sebagai alternatif, data gelombang dapat diperoleh dari model global seperti WaveWatch III NOAA atau ERA5 ECMWF. Namun, data tersebut pada umumnya disimpan pada format khusus yang memerlukan pemahaman programming untuk mengambilnya sehingga penggunaannya tidak mudah bagi sebagian besar praktisi di Indonesia. Dwave-Toolbox merupakan program dengan GUI yang dikembangkan untuk mempermudah melakukan analisis gelombang desain dengan memanfaatkan data dari ERA5 ECMWF. Pengguna dapat menggunakan program ini untuk mengunduh data gelombang dan angin di titik yang diinginkan. Kemudian dari data tersebut dapat dilakukan proses analisis yang mencakup distribusi arah dan kejadian dalam bentuk tabel dan mawar angin/gelombang serta melakukan analisis nilai ekstrim dengan metode maksimal tahunan.

Herramientas de análisis de la situación problemática en la investigación científica
Authors: Castillo Nuñez Jean Paul Simon
Published: December 2022

El inicio de una investigación científica puede ser el punto más complejo y con menor cantidad de ideas para desarrollarla. Uno de los puntos iniciales y más importantes en una investigación es el análisis de la situación problemática, puesto que, de ella parte todo el desarrollo posterior; y si no se realiza un análisis correcto y argumentado, se encontrarán puntos poco claros en distintas partes de la investigación. Es así que, existen herramientas de soporte estructuradas y aplicadas para realizar un análisis de la problemática mucho más dinámico y ordenado. El presente artículo de investigación descriptivo presenta las 6 principales herramientas en el análisis de la situación problemática: la recolección de información, el diagrama de Ishikawa, la matriz Vester, el diagrama de Pareto, la estratificación de las causas y la evaluación de alternativas de solución. En el transcurso del artículo se define cada herramienta y se detalla la manera de desarrollarlas brindando tablas y figuras modelos; así como su interpretación para un correcto análisis.
El capitalismo merma las aspiraciones investigativas científicas de la sociedad peruana
Authors: Gutiérrez Ulloa Cristian Raymound , García Salirrosas Liz Maribel
Published: December 2022

La sociedad peruana se ha mantenido relegada a través del tiempo en su desarrollo investigativo y científico a pesar que el sistema social capitalista impera en el país, otorgando una mejor calidad de vida para los peruanos, sin embargo, las entidades estatales no invierten en el desarrollo de la ciencia por lo que todas las actividades que realiza el CONCYTEC solo es una mera formalidad para tenernos aletargados con sus falsas propuestas de desarrollo. Por otro lado, el capitalismo solo tiene beneficios personales explotando las tierras peruanas por medio de sus instrumentos subyugadores de las diversas empresas multinacionales que solo deja contaminación y muerte. Finalmente, este artículo busca determinar por qué las aspiraciones investigativas científicas peruanas son desestimadas por la sociedad capitalista lo cual impide que el Perú surja como una potencia. Y según lo cavilado se debe porque no desea perder la hegemonía o que afloren nuevas formas de sistemas sociales. Por tanto, así seguiremos relegados generación tras generación hasta que se despliegue la revolución social científica.
