Ethylene Elimination Using Activated Carbons Obtained from Baru ( vog.) Waste and Impregnated with Copper Oxide.

Ethylene is a plant hormone regulator that stimulates chlorophyll loss and promotes softening and aging, resulting in a deterioration and reduction in the post-harvest life of fruit. Commercial activated carbons have been used as ethylene scavengers during the storage and transportation of a great variety of agricultural commodities. In this work, the effect of the incorporation of copper oxide over activated carbons obtained from baru waste was assessed.

School-based preventive chemotherapy program for schistosomiasis and soil-transmitted helminth control in Angola: 6-year impact assessment.

Background: A school preventive chemotherapy (PC) program for soil-transmitted helminths (STHs) and schistosomiasis has operated in Huambo, Uige and Zaire provinces, Angola, since 2013 and 2014, respectively; complemented by a school water, sanitation and hygiene (WASH) program in a subset of schools from 2016.

Methodology/principal Findings: A two-stage cluster design was used to select schools and schoolchildren for parasitological and WASH surveys.

Metastatic Renal Cell Carcinoma to the Oral Cavity.

Metastases to the oral cavity are extremely rare events, representing less than 1% of all malignant oral tumors. Renal cell carcinoma constitutes about 3% of solid tumors in adults, and it is the most frequent kidney neoplasm, representing about 90% of kidney malignancies. Due to the silent growth of this neoplasm, most patients have no symptoms and the diagnosis is belated, usually after metastases.

Methods: This is a cross-sectional study performed in two academic referral centers.

[(Dis)satisfaction of users: duplication and simultaneous use of services in family health].

This descriptive and exploratory study was performed with the purpose to identify the pattern of use of health services: duplication and simultaneous use in a District Reference Unit (URD, acronym in Portuguese) and four Family Health Units (USF, acronym in Portuguese).

[Nursing as a discipline: what scientific knowledge field identifies the profession?].

A critical reflection is proposed on the knowledge that has been produced by Nursing, that identifies it as a discipline, and on whether that knowledge is enough, based on the positive sciences and therefore with a framework of science and scientific discipline in order to build the fundamentals of care, which is the object with which Nursing works. Under a historical perspective, this paper analyzes how Brazilian Nursing, especially since the 1990s, has been dedicating itself to theoretical and practical problems and to concrete experiences on care anchored to various knowledge dimensions, signalizing the need for continuity of knowledge production that is linked to practical and routine experiences of Nursing, including other knowledge approaches that are focused on ontological, existential, dialogical and other dimensions, because the health-disease process is always complex and filled with ethical values which express the singularity of men.

Use of the reference source method to determine the half-lives of radionuclides of importance in nuclear medicine.

The reference source method associated with HPGe gamma-ray spectrometric techniques has been applied to half-life determinations of radionuclides used in nuclear medicine. Simultaneous measurements were undertaken for radiopharmaceutical nuclides such as 67Ga, 99Tcm, 123I, 131I and another radionuclide as reference. Besides optimizing the analysis time, this procedure was shown to be independent of the instrumental technique, environmental and radiochemical impurity interferences for most radionuclides.
