Expected investment of Tocantins farmers, Brazil, to apply integrated crop-livestock system during Embrapa's technology transfer

In this presentation, we report the data of these farmers collected in the beginning of the project to analyze their current conditions and expectations regarding the implementation of the new integrated system

Advances in technology transference: the experience of integrated crop-livestock-forestry (ICLF) adoption in Tocantins State.

In 2010 the Brazilian Government established a goal to reduce the emissions of greenhouse gases (GHG) by agriculture from 36.1 up to 38.9% in ten years (2010 -2020). To contribute for reaching part of this purpose in Tocantins State, Embrapa and other research and extension services partners have been conducting a project of technology transference on sustainable agricultural practices, including integrated crop-livestock-forestry (ICLF), since 2012

TESTS OF ARRANGEMENTS IN A PROTOTYPE OF A STEAM GENERATOR IN AN ABSORPTION REFRIGERATION SYSTEM

This paper presents a proposal to optimize the prototype II of a steam generator, developed by the Cooperativa de Pesquisa Norte/Nordeste de Gas Natural, RECOGÁS - UFPB, which is a component of an absorption refrigeration system of water and lithium bromide triggered by direct burning of natural gas. The optimization was carried out through changes in the arrangement, geometry, and number of the heat exchanger pipes. It was developed a computational code using F-Chart software Engineering Equation Solver® (EES), applying the principles of heat transfer to all the different geometries. As a result, their respective coefficients of heat transfer, heat flow rate and other parameters of the process were obtained. The findings are organized in a table and represented in graphs generated by the EES software, allowing to verify which factors had a greater influence on the process, as well as the most efficient geometries. Internal convection was identified as the governing factor in the heat transfer process. Some of the geometries presented satisfactory values to the product of overall heat transfer coefficient and surface area (UA) and also to the heat transfer rate in the steam generator. Other ones presented a better thermal efficiency relation with the amount of volume occupied in the steam generator. Some geometries did not present satisfactory values under any aspect

The risk analysis use supporting decision-making process on crop-livestock systems in Tocantins State, Brazil.

Decision-making about which crops will compose the crop-livestock system is an extremely important process for success integrated production. This case study aims to present the Monte Carlo (Boyle, 1977) risk analysis as a tool to support this process

Economic results of the integrated crop-livestock systems implementation in degraded pastures in Pium, TO, Brazil.

In Pium, Tocantins state, Brazil, in 2012 Embrapa developed a technology transference project in partnership with the state?s rural extension service for the consolidation of low carbon emissions agriculture. The goal was to recover the degraded grasslands of the Trigueira farm (49°1'37.44"W and 10°24'58.84"S) with low cost using a crop-livestock system

Herpetofauna of a Caatinga region in Taquaritinga do Norte, State of Pernambuco, Northeastern Brazil.

The objective of this research was to make an inventory of the herpetofaunal community of a Caatinga region from Boa Vista’s farm, in Taquaritinga do Norte, Pernambuco state, Brazil. We collected field data from August 2013 to July 2014 using diverse sampling methods: time-limited visual searches, pitfall trapping, record of vestiges and occasional encounters by local people. We could detect the presence of 42 species, 17 amphibians, and 25 reptiles. Rhinella jimi, Tropidurus semitaeniatus and Tropidurus hispidus were apparently the most abundant. The most efficient sampling method was time-limited visual searches, which allowed the record of 34 species. The species composition of the studied community is similar to other Caatinga areas in the state of Pernambuco. We highlight the importance of weirs and similar man-made habitats that provide shelter and reproduction, especially for anurans.O objetivo deste trabalho foi investigar a comunidade de herpetofauna de uma região da Caatinga na fazenda Boa Vista em Taquaritinga do Norte, Pernambuco. Os dados foram coletados de agosto de 2013 a julho de 2014 usando métodos de amostragem tais quais a busca visual por tempo limitado, armadilhas de pitfall, vestígios e encontros ocasionais pela população local. Através destes quatro métodos foram encontrados e registrados 42 espécies, 17 anfíbios e 25 répteis. Rhinella jimi, Tropidurus semitaeniatus e Tropidurus hispidus foram as espécies com maior abundância e o método mais eficiente foi a busca visual por tempo limitado com um total de 34 espécies registradas. Os dados apresentados sobre a composição são similares a outras áreas da caatinga do estado de Pernambuco, e destacam a importância dos açudes e caldeirões de lajedo para abrigar e promover locais de reprodução para as espécies, principalmente anuros.Asociación Herpetológica Argentin

Lipases and lipid droplet-associated protein expression in subcutaneous white adipose tissue of cachectic patients with cancer

Background: Cancer cachexia is a multifactorial metabolic syndrome characterized by marked loss of adipose tissue and skeletal muscle. Fat loss from adipose tissue in cancer cachexia is partly the result of increased lipolysis. Despite the growing amount of studies focused on elucidating the mechanisms through which lipolysis-related proteins regulate the lipolytic process, there are scarce data concerning that profile in the adipose tissue of cancer cachectic patients. Considering its fundamental importance, it was our main purpose to characterize the expression of the lipolysis-related proteins in the white adipose tissue of cachectic cancer patients. Methods: Patients from the University Hospital were divided into three groups: control, cancer cachexia (CC), and weight-stable cancer patients (WSC). To gain greater insight into adipose tissue wasting during cancer cachexia progression, we have also analyzed an experimental model of cachexia (Walker 256 carcinosarcoma). Animals were divided into: control, intermediate cachexia (IC) and terminal cachexia (TC). Subcutaneous white adipose tissue of patients and epidydimal white adipose tissue of animals were investigated regarding molecular aspects by determining the protein content and gene expression of hormone-sensitive lipase (HSL), adipose triglyceride lipase (ATGL), comparative gene identification-58 (CGI-58), perilipin 1, leptin, adiponectin, visfatin, and tumour necrosis factor alpha (TNF-alpha). Results: We found augmented lipolysis in CC associated with increased HSL expression, as well as upregulation of ATGL expression and reduction in perilipin 1 content. In IC, there was an imbalance in the secretion of pro-and anti-inflammatory factors. The alterations at the end-stage of cachexia were even more profound, and there was a reduction in the expression of almost all proteins analyzed in the animals. Conclusions: Our findings show that cachexia induces important morphological, molecular, and humoral alterations in the white adipose tissue, which are specific to the stage of the syndrome.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Univ São Paulo, Canc Metab Res Grp, Inst Biomed Sci, Dept Surg,Fac Med, São Paulo, BrazilSão Paulo State Univ UNESP, Exercise & Immunometab Res Grp, Dept Phys Educ, Presidente Prudente, SP, BrazilUniv Fed São Paulo, UNIFESP, Dept Fisiol, São Paulo, BrazilUniv São Paulo, Univ Hosp, Dept Clin Surg, São Paulo, BrazilUniv Mogi das Cruzes, Lab Adipose Tissue Biol, Ctr Integrated Biotechnol, Mogi Das Cruzes, BrazilUniv São Paulo, Inst Biomed Sci, Ave Prof Lineu Prestes 1524,Lab 434, BR-05508900 São Paulo, SP, BrazilUniv Fed São Paulo, UNIFESP, Dept Fisiol, São Paulo, BrazilFAPESP: 2012/50079-0Web of Scienc
