In the construction of high rise buildings, the tubular structure is more effective way of stable and economic construction. The tube system resists lateral loads i.e. wind load, earthquake load, impact loads, etc. The tube system is formed by outer perimeter tube made of closely spaced columns which acts like a dense and strong structural wall and inner core connected by spandrel beams and floor slabs with moment connections. The building behaves like a hollow cylinder cantilevered perpendicular to the ground.

Energy is essential to the society’s progress, and its efficient use is necessary in an environment with finite resources. The Brazilian industrial sector demanded a third of all energy consumed in 2017, while in the United States this share was 22% of primary energy consumption. The American government invests significantly in research and development to promote energy efficiency in all sectors of the economy since the oil crisis in 1973.

Objective: The purpose of this study was comparing the physical activity level (PAL) and nutritional status between freshmen and seniors students from Physical Education Course of a university in the State of Bahia, Brazil. Materials and Methods: The sample was selected for convenience, being 41 students (53% male) with a mean age of 22.31 (4.20) years. The subjects were divided into 4 groups, according to gender and course stage: Male Freshmen Group (MG1) and Male Veterans Group (MG8); Female Freshmen Group (FG1) and Female Veterans Group (FG8).

The process of socioespatial segregation is present in the urban context of big cities, with reasoning in the divergence of social classes and urban dynamics, old and recent. Several studies have incorporated justifications and assumptions of the motivations of this segregation. This study aimed to identify the scientific production about the spatial segregation in cities in order to analyze the main motivations and evidence of the socioespatial segregation.

In this article, it was conducted a review of the world literature about the impact of forensic evidence on decisions in criminal prosecutions. A bibliographic survey was carried out, through the search of articles published in the databases of the CAPES periodical, from 2008 to 2018. It was used the terms "Influence", "impact", "forensic evidence", "verdict”, “Criminal justice", "scene crime" and "case outcome" combined, in order to return the largest number of articles on the subject.

The urban centres are usually plagued by range of transport problems. One of the most significant urban transport problems is traffic congestion. It is experienced when the supply of the urban transport networks can no longer meet the demand for them. This study evaluates road transport infrastructure and traffic congestion in the city of Ogbomoso, Nigeria. The study used primary data which were obtained in the major traffic corridors through random and accidental sampling techniques from 60 respondents (commuters and vehicle operators) in Ogbomoso.

Problems involving chemical reactions have an important characteristic called stiffness, indicating that the solutions of the involved ODE systems vary in different orders of magnitude. So, it is needed to choose suitable numerical methods for obtaining numerical solutions that are stable and convergent at a low computational cost. The most used methods for dealing with this type of problem are the implicit methods, since they have a region of unlimited stability in the complex plane that allows large variations in step size.

This article has as the main goal to explain the modeling of prototypes of a mobile application for the management of physical activities practiced by the elderly. Starting from gerontechnology principles, it was first identified the needs and peculiarities in the management of bodybuilding physical activities practiced by the elderly; soon after, a comparative study of the functionalities and applications resources was carried out. From that onward, software engineering and its techniques as a definition of functionalities and screen prototypes for modeling were used.

The mesoregion of southeastern of Pará State, in Brazil, made up of 39 municipalities, is of great relevance under the prism of several aspects, such as economic, social and territorial. For example, according to Brandão, Castro and Neto (2017), the Gross Domestic Product (GDP) of this mesoregion, which is part of a Brazilian state, is similar to the GDP of the states of Rio Grande do Norte and Paraíba.

The concept proposed here describes about the design, construction and validation of a mobile sensory platform for crop monitoring, disaster management. In the field of agriculture, the focus is on the applications of fertilizers and pesticides which is the prime importance for crop yields. The use of drones or unmanned aerial vehicle (UAV) makes it easy because of the speed and effectiveness in spraying operations.
