Tendo em vista a finalidade essencial do estágio, Universidade Federal de Mato Grosso (UFMT) e o Tribunal Contas Estado (TCE-MT) firmaram convênio para operacionalização programa estágio. Busca-se, nesse processo, que estagiário possa revelar capacidade questionar, problematizar, conhecer movimentar-se dentro dos cenários práticas profissionais. O objetivo trabalho foi avaliar aprendizagem no s...

make or buy decision is one of the main areas of decision making for managers. transaction cost economics (tce), as an influential economic approach to the theory of the firm, tries to put forward a theoretical framework for this important decision. from tce perspective, the greater the asset specificity, the more the behavioral uncertainty and the more the transaction frequency, the more will ...

Previous studies have shown that short-term (4 weeks) or chronic (32 weeks) exposure to trichloroethylene (TCE) in drinking water of female MRL+/+ mice generated CD4(+) T cells that secreted increased levels of interferon (IFN)-γ and expressed an activated (CD44(hi)CD62L(lo)) phenotype. In contrast, the current study of subchronic TCE exposure showed that midway in the disease process both of t...

An innovative nanoscale ZnO/polybutadiene rubber composite (ZBRC) was developed as a valid alternative to TiO2 particles or immobilized TiO2 for the mineralization of chlorinated hydrocarbons without difficulties in the recovery of nanoscale photocatalyst particles. A synergistic increase in the removal of 1,1,2-trichloroethylene (TCE) through the coupled reaction processes (i.e., sorption, pho...

This study aimed to investigate the possible protective effects of Tarantula cubensis extract (TCE) on liver and brain rats exposed gentamicin (GM). A total 40 male Sprague Dawley were randomly divided into four equal groups: control, TCE, GM, GM+TCE. Some biochemical indices, apoptotic markers (B-cell lymphoma 2 [Bcl-2] Bcl-2 associated X protein [Bax]) histopathological changes evaluated. In ...

Reductive dehalogenation of tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene (DCE), and vinyl chloride (VC) was examined in four cultures containing Dehalococcoides-like microorganisms. Dechlorination and growth kinetics were compared using a Monod growth-rate model for multiple electron acceptor usage with competition. Included were the Victoria mixed culture containing D...

Naturally occurring radon in groundwater can be used as an in situ partitioning tracer for locating and quantifying non-aqueous phase liquid (NAPL) contamination in the subsurface. When combined with the single-well, push-pull test, this methodology has the potential to provide a low-cost alternative to inter-well partitioning tracer tests. During a push-pull test, a known volume of test soluti...

Improved baseplate materials are required to provide superior reliability and heat transfer as IGBT power density increases. The key is for the baseplate thermal coefficient of expansion (TCE) to be matched to the module design and to have sufficient thermal conductivity (κ). Aluminum Silicon Carbide (AlSiC), a metal matrix composite material, provides a TCE that is compatible with the attachme...

A method for the determination of trichloroethylene (TCE) in water using portable gas chromatography/mass spectrometry (GC/MS) was developed. A novel sample preparation method, liquid–liquid microextraction assisted solid phase microextraction (LLME–SPME), is introduced. In this method, 20 μL of hexane was added to 10 mL of TCE contaminated aqueous samples to assist headspace SPME. The extracti...

Volatile organic compounds (VOC) are present at over two-thirds of Superfund, Resource Conservation and Recovery Act of 1976 (RCRA), and U.S. Department of Defense sites (EPA 1996). Thus, remediation of VOCs is a top concern to the Environmental Protection Agency. Trichloroethylene (TCE) is a persistent VOC contaminant that infiltrates soil and ground water from improper disposal of dry cleanin...
