Use of Overall Equipment Effectiveness (OEE) in manufacturing cells considering takt time

Among ways of measuring and improving the efficiency of industrial processes, we highlight the use of Overall Equipment Effectiveness (OEE) also known as the Global Efficiency Index. This efficiency indicator is characterized by taking into account these factors in its calculation: available time; rhythm; product quality. OEE has been widely implemented for the control and improvement of machines. However, when it is implemented in manufacturing cells, there are parameters that must be discussed and adjusted, such as what standard time to use, because the machines in the cell have different standard times. The purpose of this paper is to use Takt time as standard time in OEE calculation as the most accurate way of measuring efficiency in a manufacturing cell. Through a case study at a metallurgical company, it has been demonstrated that the most appropriate way to measure OEE in a manufacturing cell is using takt time

Effect of forage aqueous extracts on Glycine max L. Merr., Zea mays L. and Bidens pilosa L.

The aim of the present study was to investigate the potential allelopathic effects of isolated or intercropped aqueous forage extracts on the physiological performance of soybean [Glycine max (L.) Merr.] and corn (Zea mays L.) seeds, as well as their phytotoxicity to the weed species Bidens pilosa L. Aqueous extracts were prepared at a concentration of 5%, and the tests with soy and corn were conducted by wetting the germination papers with different treatments and performing procedures within the standards of the Brazilian Rules of Seed Analysis. Tests with the cover plant extracts on the seeds of B. pilosa used BOD-type repetitions. Fifty weed seeds were placed in a gerbox with filter paper moistened with the different treatments with five repetitions. Distilled water was used as the control in all tests. Extracts of Avena strigosa Schreb and Raphanus sativus L. (radish), cultivated individually and in combination, increased the seed germination percentage (%G) and the length of soybean seedlings. Similarly, extracts of Pennisetum glaucum (L.) R.Br and Crotalaria spectabilis Roth, in individual and combined cultivation, provided gains in corn %G. Furthermore, all tested extracts suppressed germination and decreased the speed of the germination index of the hairy beggarticks when compared to the control, with the radish extract showing the greater reduction effect on the %G of the weed plant B. pilosa. Highlights: The use of Crotalaria as a cover crop has a positive effect on the initial growth of corn. The use of black oat and forage radish intercropped had the potential to increase soybean yield. The use of cover crops contributes to the integrated management of weeds. The choice of cover plant is important for the success of crop rotation.The aim of the present study was to investigate the potential allelopathic effects of isolated or intercropped aqueous forage extracts on the physiological performance of soybean [Glycine max (L.)

A SUPLEMENTAÇÃO DE ÔMEGA 3 E VITAMINA D EM OBESOS COMO ESTRATÉGIA NA PERDA DE PESO

Studies point out that nutritional supplements can contribute to the treatment of obesity and that Omega 3 can act in weight loss by reducing appetite, inflammatory markers and supplying fatty acids; increased lipid oxidation; and changes in carbohydrate metabolism. Concomitantly, research indicates low serum levels of vitamin D in obese people explained by lack of sun exposure, eating habits, greater uptake of this vitamin by adipocytes and imbalance in the relationship between calcium absorption, among others. The present work aims to point out the effects of omega 3 and vitamin D on weight loss. To this end, a narrative bibliographic review was carried out in the Scielo, LILACS and Pubmed databases, with articles from 2018 to 2022, in Portuguese and English and with the health descriptors: obesity, omega 3, vitamin D and weight loss. It was observed that omega 3, in doses of 360 mg and 240 mg up to 1080 mg and 720 mg of EPA/DHA/day, in a minimum period of 4 weeks, can help reduce weight, BMI and waist circumference. Vitamin D, from 2,000 IU/day to 50,000 IU/week, over a minimum period of 25 days, can help reduce weight, BMI, waist and hip circumference, and waist-to-hip ratio. More studies are needed to elucidate issues that are not fully understood.Los estudios señalan que los suplementos nutricionales pueden contribuir al tratamiento de la obesidad y que  Omega 3 puede actuar en la pérdida de peso al reducir el apetito, los marcadores inflamatorios y el aporte de ácidos grasos; aumento de la oxidación de lípidos; y cambios en el metabolismo de los carbohidratos. Concomitantemente, las investigaciones indican niveles séricos bajos de vitamina D en personas obesas explicados por falta de exposición solar, hábitos alimentarios, mayor captación de esta vitamina por parte de los adipocitos y desequilibrio en la relación entre la absorción de calcio, entre otros. El presente trabajo tiene como objetivo señalar los efectos del omega 3 y la vitamina D en la pérdida de peso. Para ello, se realizó una revisión bibliográfica narrativa en las bases de datos Scielo, LILACS y Pubmed, con artículos de 2018 a 2022, en portugués e inglés y con los descriptores de salud: obesidad, omega 3, vitamina D y pérdida de peso. Se observó que el omega 3, en dosis de 360 ​​mg y 240 mg hasta 1080 mg y 720 mg de EPA/DHA/día, en un período mínimo de 4 semanas, puede ayudar a reducir el peso, el IMC y la circunferencia de la cintura. La vitamina D, de 2000 UI/día a 50 000 UI/semana, durante un período mínimo de 25 días, puede ayudar a reducir el peso, el IMC, la circunferencia de la cintura y la cadera y la relación cintura-cadera. Se necesitan más estudios para dilucidar cuestiones que no se entienden completamente.Estudos apontam que os suplementos nutricionais podem contribuir no tratamento da obesidade e que o Ômega 3 pode atuar na perda de peso através da diminuição do apetite, marcadores inflamatórios e fornecimento de ácidos graxos; do aumento da oxidação lipídica; e alterações no metabolismo de carboidratos. Concomitantemente, pesquisas apontam baixos níveis séricos de vitamina D em obesos explicados pela falta de exposição solar, hábitos  alimentares, maior captação dessa vitamina pelos adipócitos e desequilíbrio na relação entre a absorção de cálcio, dentre outros. O presente trabalho objetiva apontar os efeitos do ômega 3 e da vitamina D sobre a perda de peso. Para tal, foi realizada    uma revisão bibliográfica narrativa nas bases de dados Scielo, LILACS e Pubmed, com artigos de 2018 a 2022, em português e inglês e com os descritores de saúde: obesidade, ômega 3, vitamina D e perda de peso.

Preliminary studies investigating the occurrence of Biomphalaria cousini in Brazil

Specific genetic profiles of Brazilian Biomphalaria species were previously standardized by molecular taxonomy through the analysis of restriction fragments, which were generated by digesting the internal transcribed spacer region of rDNA with the DdeI endonuclease. Biomphalaria amazonica displayed three distinct profiles. To investigate these distinct profiles, the same molecular technique, polymerase chain reaction and restriction fragment length polymorphism, was used with different endonucleases. In addition, morphological data were also used to compare B. amazonica specimens that were collected from Brazil, Colombia and Bolivia. The morphological characters of Bolivian molluscs were similar to B. amazonica, displayed a molecular profile of five restriction fragments and morphological data, whereas the Colombian mollusc population showed morphological characters similar to Biomphalaria cousini and a molecular profile of three restriction fragments, similar to B. cousini. The Brazilian specimens showed the B. amazonica and B. cousini molecular profiles as well as a third profile, which resembled a combination of the Colombian and Bolivian molecular profiles

VERTICAL ACCURACY ASSESSMENT OF THE PROCESSED SRTM DATA FOR THE BRAZILIAN TERRITORY

This research aims to determine the vertical accuracy of the Interferometric Digital Elevation Model (DEM) obtained from the processed Shuttle Radar Topographic Mission (SRTM) data. The research compared the SRTM-GL1 (Shuttle Radar Topographic Mission-Global 1) with 30-meter resolution and the following 90-meter resolution models: (a) EMBRAPA; (b) Hydrological data and maps based on Shuttle Elevation Derivatives at multiple Scales (HydroSHEDS) (HydroSHEDS), provided by the United States Geological Survey (USGS); (c) Consultative Group for International Agricultural Research-Consortium for Spatial Information (CGIAR-CSI); and (d) Jonathan de Ferranti. The accuracy analysis considered the diverse Brazilian regions, adopting 1,087 field points from the Global Navigation Satellite System (GNSS) trackers or topography methods. The Jonathan de Ferranti model achieved the best accuracy with RMSE of 9.61m among the 90-meter resolution models. Most SRTM models at 1:100,000 scale reached Grade A of the Cartographic Accuracy Standard. However, the accuracy at the 1: 50,000 scale did not achieve the same performance. SRTM errors are linearly related to slope and the most significant errors always occur in forest areas. The 30-meter resolution SRTM showed an accuracy of around 10% better (RMSE of 8.52m) than the model of Jonathan de Ferranti with 90-meter resolution (RMSE of 9.61m)

First records of molluscs naturally infected with Angiostrongylus cantonensis (Nematoda: Metastrongyloidea) in Northeastern Brazil, including new global records of natural intermediate hosts

Human neural angiostrongyliasis is an emerging infectious disease caused by nematode Angiostrongylus cantonensis. The present study investigated the presence of Angiostrongylus spp. in terrestrial molluscs collected from the following areas in the Metropolitan Region of Aracaju, Sergipe State, Brazil: Barra dos Coqueiros, Nossa Senhora do Socorro, Sao Cristovao and Aracaju. In total, 703 specimens representing 13 mollusc species were screened for Angiostrongylus spp. Larvae of Angiostrongylus spp. were found in three species. Larvae recovered from Achatina fulica were used for experimental infection in Wistar rats (Rattus norvegicus). For specific identification of nematodes, the mitochondrial cytochrome c oxidase subunit I (COI) was sequenced from both larvae and adults recovered from molluscs and rats, respectively. Infection with A. cantonensis was detected in all municipalities and in the following three host species: Bulimulus tenuissimus, Cyclodontina fasciata (Barra dos Coqueiros), and A. fulica (Aracaju, Nossa Senhora do Socorro and Sao Cristovao). Coinfections were also found with Caenorhabditis sp. and Strongyluris sp. larvae. This is the first study of the helminth fauna associated with the terrestrial malacofauna in Sergipe State, and confirms that these three snail species are involved in the transmission of A. cantonensis in the state. In addition, B. tenuissimus and C. fasciata are newly reported natural hosts of the parasite
