In this work the relevant aspects of free competition and competitivity in the Brazilian electric sector after deregulation initiated in 1995 are analyzed. The earlier model of the electric sector, a State monopoly, moved for a desverticalized structure with the separation of the...

This dissertation aims to analyze the Constitutional Principle of Free Competition, specifically regarding its role as fact the limits the abuse of economical power. In order to accomplish that goal, it was necessary to define what economical power is and in what moment the appli...

The modern stage of globalization - technological and free of borders increased the competition and obligated the players of world market be competitives. The commercial societies looked for new customers over nacional borders. To be sucessuful, joined forces by enterprise concen...

The glycine tRNA genes in silkworm Bombyx mori contain two regulatory regions upstream of the transcription start site as identified by direct transcription of 5' deletion mutants, transcription competition, gel mobility shift assays, and footprinting. A positive regulatory regio...

Sprague-Dawley rats which produce "naturally occurring" antibodies to glycerol teichoic acid (GTA) displayed immunosuppression of anti-sheep erythrocyte plaque-forming cell and serum antibody responses when a single dose of lipid-free GTA was administered 24 h before immunization...

Cytosolic free magnesium concentration [Mg2+]i and its regulation were studied in cultured embryonic chicken heart cells by use of the fluorescent indicator 2-[2-(5-carboxy)oxazole]-5-hydroxy-6-aminobenzofuran-N,N,O-triacet ic acid (Furaptra). The intracellular location of Furapt...

In the air transport industry in Chile there exists free entry, there is no fare regulation, and the role of government is defined as one of minimum intervention. However, the evolution of the industry over the last year has prompted public concern and debate about the degree of ...

Cell-free genetic circuit elements were constructed in a transcription–translation extract. We engineered transcriptional activation and repression cascades, in which the protein product of each stage is the input required to drive or block the following stage. Although we can fi...

Escherichia coli possesses three SOS-inducible DNA polymerases (Pol II, IV, and V) that were recently found to participate in translesion synthesis and mutagenesis. Involvement of these polymerases appears to depend on the nature of the lesion and its local sequence context, as i...

Several lines of evidence indicate that immunoglobulin-bound prolactin found in human serum is not a conventional complex between an anti-prolactin antibody and prolactin but a different type of association of prolactin with the Fab portion of IgG heavy chains. The complex of pro...

The mRNAs coding for the histocompatibility (H-2) antigens of the mouse have been identified by cell-free translation of poly(A)-containing RNA obtained from the livers of mice (strain A/J), followed by immunoprecipitation of the cell-free products by using an antiserum directed ...

Market regulation brings on the expectation that government's intervention improves the economy. For example, the assumption that competitive environments enable efficient allocation of resources influences the development of antitrust policies and encourages free competition. Th...

Competition among the sperm of rival males is an important evolutionary phenomenon in many organisms. Yet, despite extensive research on sperm competition in some vertebrate taxa, very little progress has been made on this topic in amphibians. Urodele amphibians (newts and salama...

The stability of pTG201 plasmid was examined by continuous culture in three genetically different Escherichia coli hosts. Two types of experiment were carried out, one with free cells and one with immobilized cells. When cells were cultivated in free continuous culture in the abs...

ABSTRACT This study aimed to evaluate the growth of Eremanthus erythropappus (DC.) MacLeish submitted to different planting spacing and growth modelling based on the diameter and crown area projection, as well as to identify the best management strategy to be applied to control ...
