| It is assumed that human tuberculosis by M. bovis in developing countries today is analogous to the situation in 1930 and 1940 in Europe, where it was responsible for more than 50% of cases of cervical lymphadenitis in children, which can be aggravated by the extra weight of AIDS/HIV. In Brazil, of 200 positive cultures of tuberculous patients, seven (3.5%), all isolated from children, were M. bovis. Five had pulmonary origin, two of which being multidrug-resistant (MDR), isoniaz Status: Completed Start date: Sat Dec 01 00:00:00 GMT-03:00 2007 |
| Recent evidence from observational studies and controlled clinical trials indicates that milk fat, although predominantly saturated, has neutral or positive effects on cardiometabolic health. Such benefits have been attributed to the complex and unique chemical nature of milk fat, which contains several compounds potentially beneficial to health, such as butyric acid (C4:0), vaccenic acid ( trans-11 C18:1), rumenic acid ( cis--9, trans-11 CLA), oleic acid ( cis-9 C18 ...

| The Compost Barn system has the purpose of reducing costs in the implementation and maintenance of animal facilities, improving herd production and sanitary indices, and enabling the correct use of dairy farming organic waste (feces and urine). The system consists of a large covered space for the cows to rest. The floor is covered with sawdust, wood cutting scraps and composted manure. The main objective of Compost Barn is to ensure comfort to the animals and a dry place for them to stay during Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2015 |

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products ...Status: Completed Start date: Mon Apr 01 00:00:00 GMT-03:00 2013 |
| Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2009 |

| Spectroscopy, which is always associated with chemometrics, is a versatile technique that is applied in several areas of science. It is fast, non-destructive, low-cost and, in addition, “clean”, requiring few or no reagents. The latter factor aligns the tool with green chemistry.

| Some results of practical interest to soil management can be extracted from the soil's water retention curve. The recent validation of the Arya and Paris model for Brazilian soils created excellent opportunities to expand the functionality of the soil granulometric analyzer which is used to obtain in detail the entire particle distribution curve. Since the granulometric analysis takes only 20 minutes, at the same time, through the developed computing implementation, the following results can als Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |

The intense world demand for food together with environmental issues related to the sustainable use of natural resources draw a picture of search for the maximum efficiency in agricultural productivity, which involves greater efficiency in monitoring crop areas. Analytical tools capable of encompassing sample variation and territorial reach demand high costs for their operation and for the replication of results. Remote sensing has proved a very efficient tool for mapping/monitoring agricultu ...Status: Completed Start date: Thu Sep 01 00:00:00 GMT-03:00 2011 |
| The soil is of vital importance for the planet. The soil is the main support of agriculture; for climate change, it is one of the regulating elements of the water cycle. Status: Completed Start date: Thu Dec 01 00:00:00 GMT-03:00 2011 |
