Background: According to the International Organization for Standardization (ISO), "quality assurance" is an all planned and systematic set of actions that are necessary to guarantee that a product or service will satisfy the requirements as to quality. As such, it is comprehensive and covers all relevant procedures, activities, and actions. This article aims to present a proposal for a checklist to be performed in the installation, operation and performance qualification for hotcells in agreement with the relevant standards recommendations.

The Forest Garden Aqueduct in the Department of Technology and Social Sciences – DTCS, Campus III, at the University of State of Bahia – UNEB is an architectural and landscape highlight that is not a historical heritage of the State of Bahiayet, although its importance. This paper searches for demonstrate the importance of perception and memory to the preservation and (re)signifying of the work and its history, arousing the community consciousness into the social, cultural and ecologic identity context, through the sense sciences, enabled by phenomenological studies.

Lifestyle can accelerate or slowdown the involution and deterioration of the different abilities. This research shows that if people over sixty five years old (EA 65+) practice physical activity on a regular basis, the progressive and generalised deterioration of bodily functions, the onset of dementia and degenerative diseases can slow down, while extending autonomy and reducing limitations in daily life. Objectives: 1. Study and analyse experts’ opinion regarding physical activity (PA) practice so that aging remains active. 2.

This paper presents the eminent threat that a forest fire represents for cultural and natural heritage in the State of Minas Gerais, Brazil, in particular the case of a fire which started on September 24th, 2017, in the forest reserve in the Caraça Sanctuary, an important site not only for its natural richness, characterized by a rich biodiversity, but also by the existence of the architectural complex of the Sanctuary, of great cultural value for the country, made up of buildings that house the old school building, a church and the old seminary.

With the economic process and science-technology development, a lot of and a lot of large-scale engineering structures. Whereas the economicprocess may be a reasonably in depth growth: high input, high consumption and high pollution, for that the energy saving technology is low, particularly in developing countries. The brightness of indoor setting is entirely maintained by artificial lighting, that has consumed an oversized variety of resources.

Communication systems demand satellite services due its global coverage and capacity to stand all-time communications. Since newer applications need high data rates, higher frequencies are often chosen while considering financial costs. In particular, recent papers show the usage for K and Ka bands. In order to fulfill these requirements, this work shows a modified circular patch antenna with fractal technology applied, which guarantees multiband operation and size reduction – an effect desired to satellite communication.

In this paper, we take the effective Hamiltonian operator until the sixth degree [3] and we apply the perturbation theory (that depends on creation operator 〖D ̂^+〗_i^a and annihilation operatorD ̂_i^a) on remaining homogenous modes after quantization of the inhomogenous modes and we have concluded the time evolution for the average ensemble of global square operator (the color magnetic energy B ̂_i^a B ̂_i^a) analytically, and we calculated this time evolution with MATLAB software, we found that life glasma (gluons) of rank 10-29sec According to coupling constant values.

The contribution of this work is focused on presenting a new approach to dispersion models of radioactive pollutants, that is, pollutants that undergo chemical reactions. The model uses the two-dimensional advection-diffusion-reaction equation to represent the dispersion of the pollutant in the Atmospheric Boundary Layer and to denote the chemical reaction that the pollutant suffers is included a source term in the advection-diffusion equation.

Based on resources from the Research and Development Program of the National Electricity Agency (ANEEL), the Pernambuco Energy Company (CELPE) is developing a research project to implement an innovative electrical energy storage system for the Fernando de Noronha. Through the project Multiobjective Optimization of Distributed Energy Resources aimed at Sustainability and Reliability in Isolated Micro grids including Energy Storage System with Batteries, the Environmental Education Program is being implemented in the region.

Teenage pregnancy represents a serious public health issue, both nationally and internationally,being a much debated subject in literature. The objective of this study is to present the characteristics of teenage pregnancy in the community of Curuçambaba, Bujaru-PA.
