Este estudo tem como objetivo demonstrar que as relações públicas podem ser um diferencial no processo de construção de marcas. A partir deste posicionamento apresentam-se as atribuições do relações-públicas nesse processo que se dá principalmente em proporcionar uma visão ampla sobre elementos como a cultura e a identidade organizacionais, além de conseguir estabelecer, com maior criticidade, relacionamentos com seus públicos de interesse, segundo suas prioridades. Partindo, de um levantamento teórico sobre tipologias organizacionais, a visão fundamentada do planejamento de uma marca, as atribuições do relações-públicas neste processo, até chegar à descrição da criação da marca Índigo Assessoria, o trabalho propõe que as fases de construção da marca devam ser embasadas em estudos sólidos de relações públicas para se obter sucesso e relevância no cenário global atual

In this work, the influence of modifications of the cp-Ti and Ti 6Al 4V alloy, by treating the surface with NaOH and depositing titanium oxide and hydroxyapatite by sol-gel method, on their biocompatibility was studied. The coatings were characterized by scanning electron microscopy and X-ray diffraction which showed that the coatings on Ti 6Al 4V are better than on cp-Ti. Adhesion tests showed that adhesion strength of the coatings on cp-Ti substrate is less than on Ti 6Al 4V as well as cytotoxicity for L929 fibroblast cells is higher

The present study was developed in two streams from the two different drainage basins located in the mid-southern region of Paraná state. In each stream were evaluated some physical and chemical parameters in open (without streamside vegetation) and shaded (with streamside vegetation) segments. Monthly samplings were carried out from January to December 2007. The following limnological parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity and current velocity. In the same stream were not observed differences among segments from the drainage basins, and nominal values and seasonal pattern have been very similar between open and shaded ambient. A Principal Component Analysis (PCA) showed small divergence between streams and segments, with separation of groups with base sampling dates. The results suggest that the region is homogeneous according to physical and chemical water conditions, therefore, stronger influenced for time factor, and diverging seasonal periods associated a climatic region condition.

Agricultural mechanization improved the efficiency of field operations by providing an increase in crop production. The intensified mechanization, however, has led to higher energy use mainly in the area of fuel consumption. The objective of this study was to compare the fuel consumption of tractors using two different tire pressures for two different types of soil during tillage with irrigated cotton in semi-arid regions. These tests were performed at the Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona with a Case 4x2 TDA 88kW equipped with an autopilot system. The results showed lower fuel consumption using a tire pressure of 124 kPa on sandy clay loan soil.

Currently, the efficiency in field operations and the increased productivity of crops is only possible with the use of agricultural machinery and equipment. This intensification of mechanized activities in agriculture, however, led to higher energy costs on farms mainly in the fuel consumption of agricultural tractors. The objective was to compare the fuel consumption of a tractor on tillage operations for irrigated cotton in semi-arid region varying two tire inflation pressures. The tests were conducted in Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona using a 4x2 TDA Case tractor equipped with a 88kw autopilot system. The results showed lower values in the hourly fuel consumption by using the minimum tire inflation pressure of 124 kPa for all tillage equipment used.
