Abstract:

A sanitização com hipoclorito de sódio é recomendada para espécies hortícolas, porém há uma preocupação sobre uma possível formação a partir deste sanitizante de trihalometanos e ácidos haloacéticos, reconhecidos como compostos cancerígenos. Com base nisto, o objetivo do presente trabalho foi estudar o efeito microbiológico e qualitativo de sanitizantes à base de extratos de taninos de Acacia mearnsii como uso alternativo ao hipoclorito de sódio em alface minimamente processada. Foram conduzidos dois experimentos. No primeiro trabalho definiram-se as concentrações mínimas inibitórias (CMI) dos

Abstract:

The current state of agriculture, where demand for safe food is increasing rapidly as a consequence of growing population, raises a number of questions related to the one health approach and sustainable animal production with minimal impact on the environment. Swine production is an important branch of food production where weaning is the most vulnerable phase for piglets, often associated with decrease of growth performance and diarrhoea. The maintenance of gut health is therefore a complex endeavour where nutrition is crucial in order to reduce the intestinal disorders. Antimicrobial resista

Abstract:

Extraction of mangrove bark with 4.0% aqueous sodium sulfite and 0.4% aqueous sodium carbonate at 100° and 2 hours gives 24-26% yields compared with extraction by water at 70° for 2 hours which gives 21%. The hot water extracts are more acidic (pH 3.6) than is the sulfite extract (pH 5.6); both are reasonably reactive toward formaldehyde (Stiasny number 70.6 using water and 85.4 using aqueous sulfite-carbonate). The <sup>13</sup>C NMR spectra of <I>R. mucronata </I>shows this tannin to have phloroglucinolic A-rings with hydroxy groups at C-5 and C-7 and pyrogallolic B-rings with hydroxy groups

The aim of this work was to assess the bioactivity of extracts of the tannin-rich plants Acacia mearnsii, Myracrodruon urundeuva, Caesalpinea bracteosa and Leucaena leucocephala against egg and infective larvae stages of Haemonchus contortus. Two in vitro assays were held: an Egg Hatch Assay (EHA) and a Larval Exsheathment Inhibition Assay (LEIA). The EHA consists of the incubation of previously recovered eggs from infected animal\'s faeces in a solution of plant extract for 24 hours and later differentiation between larvae and nonhatched eggs.

The result of this thesis is application, which makes possible to load an ECG signal, pre-process it and classify its each cycle into five classes. Percentage results of this classification are in the conclusion of this thesis.
