This paper presents the development of a pressurized ejector for particulate material handling by means of pneumatic transport, defined as a way to transport materials mainly in powder or granular form using a gas stream. Operating through high-pressure batches, the proposed equipment consists in an alternative to the conventional Pressure Vessel commonly used in pneumatic transport, having as advantages the reduction in complexity of operation; equipment dimensions; energy expenditure and production cost.

Solar technologies are continuously and rapidly growing these days. Researchers continue to look for ways to optimize the harvesting of solar energy. Application of mathematical concepts is one way of increasing the efficiency of solar panels. This study used the concept of (1) Golden ratio and Fibonacci sequence, and (2) perpendicularity angle to the sun to construct solar panels that would maximize the energy output of the panels.

The purpose of this research is to study the right of people to non-identification by anatomical sex. Identification of biological sex is an extremely common practice in society. The first legal act, after the birth with life, is the public registry and the birth certificate in which the identification of the biological sex. Gender as a historical and cultural construction should not be understood as determinant and permanent.

The path to sustainable development requires the involvement of consumers and producers of goods. Ecolabels have emerged as the primary avenue of communication between the main agents within production chains, enabling environmental impact reduction and serving as criteria for consumer choices. However, many labels are not easy to attain (mainly for small businesses), as they demand environmental and safety requirements.

This study aims to analyze the students' perceptions regarding the supervised internship of the Physical Education course of a private institution in Vitória da Conquista, Bahia. A total of 122 students answered the questionnaire with closed questions. Frequency and percentage were used to analyze the data. He noted that the students know the importance of the supervised internship for their training, but even they do not feel confident to work in the job market.

Due to the growth of overall energy consumption, alternatives for sustainable development are being heavily invested, as is the case of solar photovoltaic power plants. However, it is important to conduct the study of environmental impacts that are generated with such technology, seeking to prevent environmental damage expressive and ensuring more viable alternatives to the projects. With this, aims to raise the main environmental impacts on the physical, biotic and socio-from a deployment of a mini solar photovoltaic power plant in the Federal University of Campina Grande.

Comparism of five (5) different gillnet mesh sizes ranging from 50.8mm, 63.5mm, 78.2mm, 88.9mm, and 101.6mm was done at four (4) different sampling stations along the banks of the reservoir to evaluate the efficiency and selectivity of gillnet mesh sizes for assessing fish composition in Egbe water reservoir, between April, 2014 and January, 2016. The nets were set at 6.00pm and hauling done in the morning at 8.00am, fishermen were well monitored to avoid sampling bias and ensure a constant fishing effort.

The drying process is of great importance to the food industry. One of the best techniquesfor food drying is re-using mass and energy of air outlets from dryers. Mass and energy re-usage of waste can reduce carbon emissions and the use of fossil fuelsin industrial food processes. For this purpose, a mass and energy re-usage technique has been developed in a system of heat flow rate and condensate recovery from air outlets after drying.

Alzheimer’s disease (AD) is the most common cause of dementia. Epigallocatechin gallate (EGCG), it is most abundant polyphenolin green tea. In addition, it is the most potent neuroprotective compound in green tea. The aim of this study was to evaluate the possible neuroprotective effects of EGCG on behavioral impairments in normal and Alzheimer'srats induced by Aluminum oxide nanoparticles. Forty-eight groups of rats were divided into 8 groups, 6 rats each; Group (1) normal control, received 1ml saline 0.9% orally daily throughout the experiment.

Software industry organizations are known by being intensive in producing different types of knowledge during all the software development process. That's because this industry builds different types of software-based solutions, as well as storing a large amount of data for their customers and their projects. This amount of data is stored in databases so that it can be used in different tasks in the organization in the future. Thus, many of these databases are characterized as Big Data.
