Statistical Process Control (SPC): a control tool against waste of inputs in brazilian dairy

By reason of the requirements of quality on the part of consumers and regulatory agencies, the dairy industries require tools capable of optimizing their processes in virtue of threats from countries which have a lower cost of production. The Statistical Process Control (SPC) is a powerful tool to evaluate and monitor the process in relation to their stability. This paper presents an application of Statistical Process Control (SPC) in a dairy plant located in the south of Minas Gerais. The process analyzed was the packaging of butter in 200g pots. The purpose of this article is to identify the actual state of the filling process of butter in this dairy and compare them with the requirements established by legislation. Therefore, was used samples and control charts to demonstrate the current state of the process and normality tests, in particular the t-student. The results demonstrate that the industry does not harm the consumer and that is faithful to the legislation. However, it was identified that in case the industry presents an overweight in nominal content of each package, which leads to considerable injury once the feedstock used in the production of butter (cream) is of great economic value

Análise da articulação do Projeto Pré-Enem Comunitário da Universidade Federal de Alagoas com as Políticas de Inclusão Social

O artigo analisa a articulação do Projeto Pré-Enem Comunitário da Universidade Federal de Alagoas com as Políticas de Inclusão Social, em particular: a Política de Cotas e o Programa Universidade para Todos. Trata-se de pesquisa qualitativa, quanto ao método e à forma de abordar o problema. A investigação consiste no enquadramento do projeto aos três eixos integradores necessários à articulação contidos na Política Nacional de Extensão ao mesmo tempo em que estabelece correlações demonstrando a convergência de objetivos e finalidades entre o projeto e as políticas destacadas. Os resultados apontam para a adequação da ação aos referidos eixos e confirma o apoio às políticas. Conclui-se que o estudo contribui para as discussões sobre: a responsabilidade social das IFES; a necessidade de financiamento das ações de extensão; e o fortalecimento do fazer extensionista

Cultivo do camarão marinho em água doce em diferentes densidades de estocagem

The objective of this work was to evaluate the effect of stocking density in Litopenaeus vannamei rearing in fresh water. The evaluated densities were: 5 (D5), 10 (D10), 15 (D15), 20 (D20), 25 (D25) and 30(D30) shrimp per square meter. The experimental design was completely randomized, with two replicates. The performance of shrimp and the physical and chemical parameters of water were evaluated. Mathematical models were generated to estimate the zootechnical parameters of L. vannamei. The mean alkalinity of water was 36.8±3.06 mg L-1, and the mean hardness was 38.21±3.07 mg L-1. At 52 days of rearing, treatment D5 had the best results on weight (5.40±0.99 g) and length (9.50±0.20 cm), but the weight did not differ significantly from treatments D10, D15 and D25. Treatment D25 had the best shrimp survival rate (72.10±9.3%). Based on the mathematical models of weight and length as function of rearing time, it was found that higher stocking densities provide shrimp with less weight and length gain.O objetivo deste trabalho foi avaliar o efeito da densidade de estocagem no cultivo do camarão marinho Litopenaeus vannamei, em água doce. Foram avaliadas as seguintes densidades de estocagem: 5 (D5), 10 (D10), 15 (D15), 20 (D20), 25 (D25) e 30 (D30) camarões por metro quadrado. O delineamento experimental foi inteiramente casualizado, com duas repetições. Foram avaliados o desempenho zootécnico dos camarões e os parâmetros físicos e químicos da água. Os parâmetros zootécnicos de L. vannamei foram estimados por meio de modelos matemáticos. A alcalinidade média da água foi de 36,8±3,06 mg L-1, e a dureza média de 38,21±3,07 mg L-1. Aos 52 dias de cultivo, o tratamento D5 foi o que promoveu os melhores resultados em peso (5,40±0,99 g) e comprimento (9,50±0,20 cm), no entanto, não diferiu significativamente dos tratamentos D10, D15 e D25 em termos de peso. O tratamento D25 teve maior sobrevivência de camarões (72,10±9,3%). Com base nos modelos matemáticos de peso e comprimento em função do tempo de cultivo, concluiu-se que maiores densidades de estocagem proporcionam camarões com menores ganhos de peso e comprimento, em comparação com as menores densidades

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
