A indústria da construção civil é caracterizada como a principal consumidora dos recursos naturais, isso é propiciado pelo grande número de obras que são necessárias para o crescimento do país. No entanto, o alto consumo dos materiais torna-se um fator que limita a execução das mesmas. Por isso, a adição de diferentes materiais na produção de componentes, assim como a utilização de resíduos, que geralmente possuem um custo de descarte e/ou necessitam de tratamento específico, se torna um atrativo técnico-econômico a pesquisadores e, principalmente, ao mercado consumidor. O presente trabalho tem como objetivo avaliar o comportamento de concretos convencionais com adição de resíduos de marmoraria frente às propriedades mecânicas e de durabilidade. Para tanto, realizou-se um estudo experimental onde foram testados teores de 10 e 20% de adição dos resíduos (em massa) com relação a quantidade de cimento. Com relação à resistência à compressão, a incorporação do resíduo não apresentou influência significativa quando comparado com um concreto sem adição. Entretanto, considerando a absorção de água por capilaridade, como um indicativo de durabilidade verificou-se que, a adição de um teor de 10% de resíduos se apresentou como uma boa opção de melhoria dessa propriedade.
For a long time the concepts of economic growth and entrepreneurship were understood as essential for the development of a country. Schumpeter introduced the concept of entrepreneurship, seeking to reinforce the association between entrepreneur and innovation as a proportioning element of economic development. According to Schumpeter (1982), entrepreneur is the person who can convert an idea or invention into a successful innovation. The current developmental framework of society and the constant economic, social and cultural transformations contribute significantly to the changes in the ways of thinking and acting of contemporary man. This study aims to analyze and understand the entrepreneurial profile of a municipality in the central region of Rio Grande do Sul State. Regarding the method, it is classified as a quantitative study (survey) composed of closed questions with Likert scale elaborated based on in literature. The research results allowed us to understand the profile of entrepreneurs, characteristics, types of investments, level of competitiveness, degrees of behavior, etc. Findings are of paramount importance for growth, new business propositions, new business conceptions, new opportunities. Brazil is a country where people aspire for technology, innovation and creativity. As a result, the study made it possible to understand the entrepreneur of rural entrepreneurs, and to verify that in recent years, there have been changes in production cultures, the need for technological adaptations, and the search for management knowledge, to maintain the competitiveness and economic growth of companies.
The Federal University of Santa Maria - Cachoeira do Sul Campus began its activities in 2014 with five graduate courses: Architecture and Urbanism; Agricultural Engineering; Electrical Engineering; Mechanical Engineering; and Transport and Logistics Engineering. The need of technological professionals to meet regional and national demand was considered at the UFSM-Cachoeira do Sul (UFSM-CS) conception. However, the population of Cachoeira do Sul and nearby cities do not know about the courses offered by UFSM-CS. In order to alleviate this problem, the program UFSM-CS goes to Schools is in operation, whose main objective is to present the courses offered by UFSM-CS to high school students in public and private schools. This project has been developed in two stages: in the first stage, a questionnaire about the previous knowledge of the school community about the UFSM campus is applied. In the second stage, a cycle of lectures in public and private schools to show the undergraduate courses in the Cachoeira do Sul campus is done and then a new questionnaire is applied to check if the lecture cycle has indeed encouraged these students to enter UFMS-CS and/or another institution. A statistical analysis of the data obtained through questionnaires is presented to support extension projects with the schools of Cachoeira do Sul and region. Results show that 80% of students intend to enter a higher education institution and 70% do not know which courses are provided by UFSM-CS. After the presentation of the seminars, 92% of the students told the seminars were enlightening.
O resíduo que se acumula no processo de sedimentação no tratamento de água é chamado de lodo de estação de tratamento de água (LETA), o qual necessita de adequada disposição. O objetivo desta pesquisa é avaliar o comportamento mecânico e hídrico do uso de LETA em misturas com solo argiloso laterítico, para aplicação em camadas de aterros sanitários. Foram avaliadas misturas com a substituição parcial de solo por LETA nas proporções de 15%, 30% e 50%. No ensaio de permeabilidade, o material mais impermeável foi a mistura 85% Solo + 15% LETA, com k igual a 7,82E-10 m/s. Com relação à resistência ao cisalhamento, o ângulo de atrito aumentou conforme incrementou-se LETA no solo, reduzindo a coesão dos materiais. Do solo para mistura 50% Solo + 50% LETA houve uma redução na coesão efetiva de 41,13% e um aumento no ângulo de atrito efetivo de 74,68%. Definiu-se a mistura composta de 85% Solo + 15% LETA como a melhor para aplicação em camadas de aterros. Palavras-chave: Resíduos Sólidos. Lodo de ETA. Camadas de Aterro Sanitário.
