The method used was the bibliographic review and analysis of secondary data from different sources, associated with the Market Orientation Theory and the Value Chain Theory. Nowadays, China is Brazil＇s main commercial partner in the international market, but taking into account the chicken meat and its derivatives, having Brazil as the first worldwide exporter and China, the second largest consumer, an effective commercial relationship has not been established yet. To understand the poultry market exchanges between Brazil and China, a framework was built to demonstrate the characteristics and factors found to influence country negotiations, considering current reality and future perspectives. Considering the Theory of Market Orientation, it is concluded that Brazil has effective conditions to consolidate itself as a major supplier of chicken meat and derivatives to China, because it shows determinant characteristics and market factors that allows the association of the national poultry value chain to the demands of the Chinese consumers, but some adjustments are needed in the sphere of international politics.展开更多

ECG （electrocardiography） is one of the most widely used method for evaluating the structure-function relationship of the heart in health and in sickness. Due to incomplete skin development, premature newborns have some special requirements to the ECG monitoring electrodes. Contact ECG monitoring adversely affects the health and comfort of the newborns. The goal of this study is to determine the feasibility of using RF （radio frequency） in ECG signal remote sensing. This requires studying the interaction mechanisms between RF fields and biological tissues The ECG current propagated from the heart through the skin has an effect on the permittivity of the skin which is frequency dependent. Thus, the feasibility of detecting the change of the relative permittivity in the presence of ECG signal is also discussed. The RF biological tissues response is simulated using MATLAB software in preparation for experimental validation.展开更多
