It is the most widespread, costly disease in dairy farms and a great concern for many producers in developing countries like Ethiopia. The study was conducted to test the antimicrobial susceptibility of identified pathogens from mastitic cattle. Out of 384 lactating cows examined in the course of the study period, 116 (30.21%) cows had mastitis. The results of bacteriological analysis of cultured milk samples had shown three major strains of pathogenic bacteria namely <em>Staphylococcus aureus</em>, <em>Streptococcus agalactiae</em> and <em>Escherichia coli</em> were isolated from 81 cows, 48 bacterial isolates (59.26 %) were identified as <em>S. aureus</em>, 31 bacterial isolates (38.27%) were identified as <em>Str. agalactiae</em> and two bacterial isolates (2.47%) were identified <em>E. coli</em> (2.47%). The antimicrobial agents used were gentamycin, kanamycin, erythromycin, chloramphenicol, streptomycin amoxicillin, penicillin and ampicillin. The in vitro antimicrobial susceptibility test showed some degree of resistance in varying proportions of isolates. Some of the bacterial isolates exhibited even resistance to two or more antibiotics. S. aureus represented 95.8 % of the total isolates, was found resistant to penicillin while 93.7% of the total isolates were found sensitive to gentamycin. On the other hand, from the total isolates of <em>Str. agalactiae</em>, the maximum resistance was recorded in ampicillin (35.5%), and sensitivity was recorded in penicillin (83.9%). All of the <em>E. coli</em> isolates were resistant to amoxicillin, ampicillin, and penicillin while all of them were susceptible to gentamycin and streptomycin. The average susceptibility of <em>S. aureus</em>, <em>Str. agalactiae</em> and <em>E. coli</em> strains to all antimicrobials tested in this study were 37.5%, 41.9% and 37.5%, respectively. In comparison, the average resistivity of all antimicrobials tested was 41.4%, 13.3%, and 43.8% of <em>S. aureus</em>, <em>Str. agalactiae</em> and <em>E. coli</em>, respectively. For the bacterial isolates tested for antimicrobial susceptibility, gentamycin, chloramphenicol, and streptomycin were the drugs more active, while the majority of isolates were resistant to amoxicillin, ampicillin, and penicillin. This antibiotic resistance development among these bacteria may pose a problem of concern. Hence, the use of antimicrobials in both the treatment and prevention of intra-mammary infections must be based on in vitro antimicrobial susceptibility test.</p> Teshome Gemechu Chawicha Hasen Awl Yunus Murga Soma Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0/ 2021-09-16 2021-09-16 3 e2021010 e2021010 10.29327/multiscience.2021010 COVID-19 segundo as concepções dos alunos da Educação Básica na cidade de Belém, Pará, Brasil https://malque.pub/ojs/index.php/msj/article/view/145 <p lang="es-ES" align="justify">O presente estudo investigou os conhecimentos prévios dos alunos da educação básica em relação aos sintomas, transmissão, prevenção e fake news associadas a COVID-19. O estudo foi realizado com alunos da educação básica da cidade de Belém, estado do Pará, por meio de questionário online. Participaram 217 alunos que: obtiveram informações da COVID-19 pela escola, televisão, amigos, e redes sociais. Eles relataram como sintomas: dificuldade para respirar, tosse, dor de garganta. A transmissão: espirro, tosse e contato com pessoas já infectadas. Prevenção: lavar as mãos com água e sabão, evitar aglomerações, cobrir o nariz e a boca ao tossir. Em relação às fake news, obtiveram as informações pela internet, redes sociais, e conversas com familiares. Verificam a veracidade das informações, acreditam que as fake news podem prejudicar a economia, gerar o caos no sistema público de saúde, distorcem notícias verdadeiras e geram pânico. Sua divulgação pode trazer malefícios para a população em geral. Portanto, acreditamos que os alunos podem contribuir com a conscientização de familiares e amigos em relação a COVID-19 e fake news.</p> Erival Gonçalves Prata Leandro Marques Correia Adriana De Almeida Sanches Renan Ferreira de Sousa Josiney Farias de Araujo Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-07-28 2021-07-28 3 e2021009 e2021009 10.29327/multiscience.2021009 Designing and manufacturing a solar rotary dryer for drying beef and studying its quality and storage characteristics https://malque.pub/ojs/index.php/msj/article/view/148 <p>An indirect rotary solar dryer for drying beef has been manufactured and designed in the food engineering workshop at College of Agriculture, Basrah University. The dryer contains a solar collector with length of 1.70 m, depth of 0.25 m and width of 0.30 m, a chimney and tubular met at mesh. Also, the solar collector includes a drying tube which has a capacity of 5 kg and is made of galvanized iron. Throughout the study period, there was a significant increase in the solar radiation energy (p less than 0.05) with daylight hours passed till 12:00 PM. In addition, the maximum level of solar energy has been 810.55 W / m2, which is after that reduced to 680.10 W / m2 at 4:00 PM. In rotary solar dryer, the drying efficiency was 65.91 % at a 60 <sup>o</sup>C and decreased with the increase in drying temperature. In the drying tube, the average temperature reached 80 <sup>o</sup>C at 1:00 PM, while the air temperature was 43<sup>o</sup>C. Unsalted and salted beef were dried with the use of different period of storage (0, 14, 28, 42, 56 and 70) days and various (60, 70, and 80) °C to study their qualitative properties. The resulted indicated that there is a decrease in moisture content with the increase in drying time. Furthermore, the chemical composition related to dried unsalted and salted beef indicated that there is a decrease in moisture percentage, while there is an increased ash percentage, fat and protein after the process of drying. There is an increase in the moisture percentage throughout the periods of storage different from other percentages of the chemical composition which have been reduced with the increase in the periods of the storage. It was shown via the results that there was a decrease in the rehydration with increasing the drying temperature values for unsalted and salted dried beef. Results have reported that there has been a decrease in microbial content regarding dried unsalted and salted beef. Also, it was shown by the results that the model of Artificial Neural Networks (ANNs) showed good results of predicted content of the moisture.</p> Hassan Al-Rubai,y Mohammed Eskander Khalid Abdul Hassan Yasir Al-Hashami Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0/ 2021-09-29 2021-09-29 3 e2021011 e2021011 10.29327/multiscience.2021011 Study of qualitative characteristics of burgers from beef partially replaced by truffle during different storage periods https://malque.pub/ojs/index.php/msj/article/view/51 <p>The current study aimed at the possibility of substituting truffles instead of beef in the beef patties at rates of 0, 20, 40 and 60% for different storage periods (0, 15, 30 and 60 days in freezing at a temperature of -18 °C) and to study the qualitative and microbial characteristics. 40% showed a significant difference in all the studied traits and a decrease in the indicators of oxidation and rancidity, as was observed a significant reduction in the peroxide values and the free fatty acids percentage of the meat samples treated with plant extracts compared to the control treatment which amounted to 4.51 mm caffeine/kg of fat and 1.15% respectively on day 60 of preservation as treated samples remained within standard limits. The replacement samples also showed a significant decrease in the total number of cold-loving bacteria and bacteria compared to the control treatment during the different storage periods.</p> Gaidda Ali Makki Esraa Yacoob Yousif Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-04-08 2021-04-08 3 e2021007 e2021007 10.29327/multiscience.2021007 Capacidades físicas e medidas antropométricas entre praticantes de Crossfit® e Crosstraining https://malque.pub/ojs/index.php/msj/article/view/50 <p>O Crossfit® e o Crosstraining são programas de treinamento físico extremo que incluem a realização de sessões de alta intensidade, com amplas variedades de exercícios funcionais, objetivando o desenvolvendo de forma global das capacidades físicas dos indivíduos. Visto a ampla utilização de ambos os métodos, suas semelhanças e afalta de estudos que buscam compará-las, o objetivo do presente trabalho foi verificar se há diferenças entre as capacidades físicas (salto vertical, salto horizontal, barra fixa, salto no caixote, flexão de braço e burpee) e antropométricas entre os praticantes de Crossfit® e crosstraining. Os dados foram analisados utilizando o programa estatístico SPSS versão 20.0. Foram expressos em média ± desvio padrão e o teste de normalidade de Shapiro-Wilk foi executado. Para comparação das médias, foi utilizado o teste T de student para amostras independentes.

Pode-se concluir que não há diferença nas capacidades físicas e medidas antropométricas entre os indivíduos avaliados.</p> Willian Fernando Willian Santos João Barbieri Leonardo Emmanuel de Medeiros Lima Henrique Miguel Dilmar Guedes Jr Rodrigo Pereira da Silva Enrique Marchioni Roberto Moriggi Jr Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-02-24 2021-02-24 3 e2021006 e2021006 10.29327/multiscience.2021006 Bacteriological examination of Obibia stream during wet and dry seasons in Awka, Anambra State, Nigeria https://malque.pub/ojs/index.php/msj/article/view/49 <p>Diseases caused by contaminated water consumption are among the leading causes of death in children, the elderly, and people who are immunocompromised. Hence there is an important need to ensure that drinking water sources are free from pathogens that can endanger the health of consumers. This study was undertaken to investigate the influence of seasonal changes on the bacteriological distribution of the Obibia stream. A total of 30 water samples (500 ml each) were collected for the study at rainy and dry seasons for a period of May to July 2015 and December 2015 to Feb 2016, respectively. Bacteria present in the water samples were isolated and characterized using 16s rDNA sequencing. Total heterotrophic aerobic bacterial counts were determined using standard microbiological biochemical procedures. Their frequencies of occurrence were also determined. Total heterotrophic aerobic bacterial counts (THABC) were significantly higher (P=0.039) &gt; total coliform count &gt; fecal coliform counts &gt; Salmonella - Shigella counts &gt; Vibrio counts throughout the periods of sampling in the wet season, with the highest counts obtained in July. THABC was also significantly higher (P = 0.018) than other examined bacterial groups and had its peak in January. Bacterial genera present in the examined samples were identified as Shigella, Salmonella, Escherichia coli, Vibrio, Enterobacter, Klebsiella, Enterococcus, Staphylococcus, Pseudomonas, and Serratia with their respective frequencies of occurrence as 4.55%, 18.18%, 13.64%, 27.27%, 4.5%, 9.09%, 4.55%, 4.55%, 9.09% and 4.55% in the wet season. Their respective occurrences in dry season were 4.17%, 16.67%, 12.50%, 25.00%, 4.17%, 8.35%, 4.17%, 8.33%, 8.33%, and 8.33%. This bacteriological analysis has shown that wet season samples from the Obibia stream had more bacterial counts than dry seasons. Thus, the water samples from it require further purification steps before being used for domestic purposes by the inhabitants of its surrounding communities.</p> Gloria Chinelo Ike Frederick John Chidi Odibo John Joseph Okeke Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-02-12 2021-02-12 3 e2021005 e2021005 10.29327/multiscience.2021005 Terapia neural e auto hemoterapia, pH e condutividade de misturas de sangue com cloridrato de procaína https://malque.pub/ojs/index.php/msj/article/view/48 <p>A terapia neural é um tratamento que objetiva a auto regulação do organismo através da aplicação de anestésicos locais em baixas concentrações, como o cloridrato de procaína, em locais escolhidos pela história de vida do paciente. A terapia neural é difundida na Alemanha, Áustria, Argentina, Canadá, Colômbia, Costa Rica, Cuba, Espanha, Estados Unidos, México, Suíça. Os anestésicos locais em baixas concentrações funcionam como drogas dielétricas e atuam no potencial de membrana das células enfermas. A associação com a auto hemoterapia e hemopuntura é benéfica. O objetivo desse trabalho é demonstrar a condutividade e o pH do sangue total juntamente com o cloridrato de procaína a 0,7% com bicarbonato de sódio em várias proporções. Cada vez mais a medicina busca novas maneiras de fazer com que o corpo responda às agressões dos microrganismos de uma forma prática, simples e de baixo custo. A associação da Terapia Neural com a auto-hemoterapia e hemopuntura na prática clínica potencializa futuros tratamentos.</p> Leonardo Rocha Vianna Bruna Aparecida Lima Gonçalves Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-01-20 2021-01-20 3 e2021004 e2021004 10.29327/multiscience.2021004 Comparative assessment of three yeast samples for wine production from pineapple https://malque.pub/ojs/index.php/msj/article/view/47 <p>Pineapple is an abundant fruit in Nigeria, which usually suffers post-harvest spoilage due to lack of preservation techniques. Its rich sugar content makes it a suitable substrate for wine production, which becomes a useful alternative to curbing its post-harvest spoilage. This research compared the production of wine from pineapple using Saccharomyces cerevisiae, Saccharomyces bayanus, and Saccharomyces ellipsoides. Yeast viability was assessed on YPG medium. To each fermenting jar was poured sterilized 3000 ml must, comprising of a mixture of juice and 6 ml of each yeast inoculum. Sodium metabisulphite (0.4g/l) was also aseptically added to each of the fermenting jars as a preservative and the fermenting jars were sealed with corks. Fermentation was allowed for twenty-eight (28) days within which different physical analyses were carried out (pH, temperature, titratable acidity, specific gravity, reducing sugar, alcoholic content) for each day. Sensory evaluation of the finished products was conducted and the overall level of acceptance was determined. The viable counts of Saccharomyces cerevisiae, Saccharomyces bayanus, and Saccharomyces ellipsoides after growth on YPG medium were 3.3 x 10<sup>6</sup> , 3.5 x 10<sup>6</sup> , and 3.8 x 10<sup>6</sup> cfu/ml respectively. There was decreased pH, reducing sugar, and a specific gravity of the wine samples while, there was an increase in titratable acidity, alcohol content, and temperature. Significant differences (p&lt;0.05) existed in the overall acceptability of the wine samples with S. bayanus fermented wine having the least acceptance by taste panelists. Pineapple makes a good compatible raw material for wine production using varying yeast samples.</p> Chukwuma Chrisaugunus Ekechukwu Chukwunonso Christian Ikele Chukwuemeka Augustine Okafor Ikenna Chukwudi Igwebuike Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-01-20 2021-01-20 3 e2021003 e2021003 10.29327/multiscience.2021003 pH e condutividade do cloridrato de procaína em diferentes concentrações utilizadas em terapia neural https://malque.pub/ojs/index.php/msj/article/view/46 <p>O cloridrato de procaína é um anestésico local utilizado na terapia neural com resultados surpreendentes em diferentes tipos de pacientes e tratamentos. A terapia neural foi desenvolvida principalmente, pelos irmãos alemães Huneke e é praticada há mais de 100 anos. Em 1940, Ferdinand Huneke verificou o desaparecimento súbito de uma dor no ombro de um paciente após aplicação em uma cicatriz de osteomielite na perna. Esse tratamento é difundido na Alemanha, Áustria, Argentina, Canada, Colômbia, Costa Rica, Cuba, Espanha, Estados Unidos, México, Suíça e hoje vem se difundido também no Brasil e vários outros países. Tem reconhecimento internacional como método curativo e eficaz em muitas enfermidades. Para conhecer melhor as características da principal substância e das soluções utilizadas na terapia neural, bem como a velocidade de resposta do organismo após sua aplicação, foram realizadas experimentos para estabelecer o comportamento elétrico de seus componentes. O objetivo desse trabalho é demonstrar e avaliar o pH e a condutividade de diferentes concentrações de soluções de cloridrato de procaína.</p> Leonardo Rocha Vianna Bruna Aparecida Lima Gonçalves Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2020-12-21 2020-12-21 3 e2021002 e2021002 10.29327/multiscience.2021002 Aspectos físicos do solo em diferentes sistemas de manejo como indicador de sustentabilidade https://malque.pub/ojs/index.php/msj/article/view/44 <p>Com objetivo de avaliar as características físicas dos solos em áreas sob diferentes usos no Projeto de Desenvolvimento Sustentável Porto Seguro, localizado no município de Marabá - PA, foram utilizados indicadores físicos do solo, como a densidade do solo que influencia diretamente na densidade de partículas e porosidade do solo. Foram coletadas amostras de solo na camada de 0 a 15 cm pelo método de anel volumétrico (MAV), segundo Embrapa (1997) de áreas pertencentes a três diferentes usos (mata nativa, sistema agroflorestal - SAF e cultivo de mandioca). Os resultados foram submetidos à análise de variância ANOVA e a comparação entre as médias foram feitas pelo teste de Tukey a 5% com auxílio do programa PAST. O SAF implementado não só ajudou na proteção como melhorou as qualidades físicas do solo, aumentando o fornecimento de matéria orgânica que ajuda na formação de agregados e, por conseguinte, ajuda a conservar os macroporos que são importantes para o processo de infiltração.</p> Bruna Stephane Nascimento da Silva Ellen Patrícia Nascimento Victória Oliveira Assunção Lima Larissa Carvalho de Oliveira Nássila Ribeiro Galina Gleidson Marques Pereira Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2020-12-06 2020-12-06 3 e2021001 e2021001 10.29327/multiscience.2021001 Sistematização de uma sessão de treinamento especifico para surfistas https://malque.pub/ojs/index.php/msj/article/view/52 <p>Nas últimas décadas o surf cresceu de forma significativa no Brasil. Atualmente são mais de 3 milhões de praticantes, tornando o nosso país o líder com o maior número de adeptos no mundo. Esses dados já justificam a importância de sugerir um modelo de sessão de treinamento físico específico para a modalidade surf, com o objetivo de melhorar o rendimento dos surfistas, além de prevenir o risco potencial de algumas lesões. O surf, como esporte, é classificado como uma modalidade complexa de coordenação. A sua prática exige o treinamento e desenvolvimento de diferentes capacidades e habilidades físicas. A sessão de treinamento proposta no presente estudo é uma alternativa de aula que pode ser utilizada para o público praticante de surf em geral. No entanto, um surfista competitivo pode, em algum momento de sua periodização do treinamento, utilizar tal modelo de sessão, considerando a individualização, o volume e a intensidade da carga.</p> Krom Marsili Guedes Pedro Souza Rodrigo Pereira da Silva Dilmar Pinto Guedes Jr Copyright (c) 2021 Multidisciplinary Science Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2021-05-06 2021-05-06 3 e2021008 e2021008 10.29327/multiscience.2021008
