Incidence and jeopardize factors of knee injury in the case of male volleyball players in Ethiopia

Background: Volleyball is one of the most widely played sports in addition to football and basketball. International de Volley-Ball Federation (FIVB) represents about 800 million players in approximately in the world played volleyball. While a large body of research has been conducted regarding the nature and prevalence of volleyball injuries internationally, but not conducted in Ethiopia broadly.

Design and implementation of interoperability services within the serpolet system

In this paper, we propose an innovative concept of "Application Service Provider LMS (ASP LMS)" which promotes the opening and the interoperability of the learning management systems (LMS) and the sharing of learning services and resources. The goal of this opening is to make the interaction between systems easier, to facilitate the sharing of resources and services between systems. With the introduction of this economic model this system widens the market of the Open and Distance Learning (ODL).

Analytical study on virtual touch perspective by mixing 7d holographic projections with transducers

We are using light waves formed using transducers for the projection of 7D holograms. Using this we will be literally touching the 7D virtualization of light waves. By using the concept of ultrasonic transducers the combinations so formed combined with 7D hologram with respect to the angles associated with it will give the resultant touch feel.

Axioma caac – conhecimento, atitude e autoconfiança: competências básicas para valorização profissional no Brasil

Trata-se de um artigo de opinião sobre competências básicas para valorização do profissional de enfermagem. A enfermagem é permeada por imagens estereotipadas e primitivas, percepções errôneas que derivam da história da profissão e que se perpetuam até os dias de hoje. A importância desse reconhecimento encontra-se, entre outros, na influência que a valorização da profissão, em suas variadas dimensões, tem no desempenho profissional. Sugere-se a implementação de três competências básicas: o conhecimento em enfermagem, atitude profissional e autoconfiança.

Detection of brain signals using electroencephalogram received by silk electrospun sheet for the movement of paralyzed anatomical parts through tissue engineering

Silk is a natural bio polymer which contains many multifunctional management and administrative function that influence on human body like brain and different anatomy of body and osteotomy managements. There is a vast unknown challenges with silk and its performance till now on going research for future. In this paper, I attempted to show brain influence through modification of silk fibers by electro -spinning process and that will take a signal from brain and connect this signal to the anatomy of human body to work or make movement for paralyzed patients.

Bsc in Brazilian companies: Differences in use by size and industry

The Balanced Scorecard (BSC) is a tool created by Kaplan and Norton in the 1990s, whose objective is to assist organizations in visualizing the company as a whole, providing strategic business management from four perspectives: financial, customers, internal processes and learning/knowledge. The aim of this article was to analyze how, and if, the tool is used in small Brazilian companies. To do so, the quantitative research employed by Giannopoulos et al. applied in companies located in Cyprus and the United Kingdom in 2013 was used as basis.

Quantum fitometeorology: factor analysis of the three-hour measurements of four meteorological parameters during the vegetation periods 2012-2018

Text of annotation. Factor analysis of three-hour dynamics from 01.01.2012 to 31.10.2018 of four meteorological parameters: atmospheric pressure; air temperature; relative humidity; dew point temperature was carried out by the method of identification (weather station Yoshkar-Ola, Russia, WMO_ID=27485).Power selection when accounting periods of the growing season of birch from 01.05 till 30.09 made 8558 instead 19713 lines in comparison with the continuous series, while there have been significant changes in the laws.

Coworking: key elements for the innovative entrepreneurial environment

The offer of coworking spaces have been growing in Brazil in recent years, due to the search for cost reduction and collaborative work. These spaces allow the shared use of resources, ideas and services. The present study targeted the identification of the fundamental elements for a coworking space, in order to create an innovative and enterpreneurial environment.

Presence of α-amylases inrhizobacterias isolated from amazonian soils

Several bacteria found in nature produce α-α-amylases. This research evaluated the presence of thermotolerant α-amylases in rhizobacteria isolated from legume nodules to use for the conversion of starch from amylaceous plants. Forty rhizobacteria were tested for the presence of these α-amylases, as well as for the thermotolerance characteristic. Nineteen bacteria produced an amylolytic halo and eleven were showed to be thermophilic.

Effect of temperature and ph on amylolytic activities of bacillus atrophaeus and paenibacillus polymixa isolated from amazonian soils

The "Pro-Alcohol" program in Brazil is based on the use of sugarcane and, since the harvest is carried out once a year, there is a period of inactivity between harvests. As a result, several mills began to use in the off-season, starch producing species for alcohol production. In order to use these plant species, it is necessary the use of α-amylases. The search for thermotolerant amylases in bacteria isolated from Amazonian soils is an important strategy to reduce and even stop importing these enzymes.
