DETERMINATION OF THE PHYSICAL-CHEMICAL PROPERTIES OF SOLID WASTE FOR USE IN THE PYROLYSIS PROCESS

Brazil is still very incipient in the use of Municipal Solid Waste (MSW) for the generation of fuels and electric energy. Law No. 12.305/10 establishes the National Solid Waste Policy (NSWP), considered efficient and adequate for solving the problems caused by MSW. However,  NSWP is considered a process of high cost when compared to  landfill. Due to the need to seek clean and renewable forms of energy, the pyrolysis process can be an alternative in the  primary energy production. This is a thermochemical conversion process, which occurs at high temperatures and involves several chemical reactions, whose liquid organic aqueous fraction is called bio-oil. This work studied the physicochemical characteristics of some types of waste (food scraps, cardboard and paper) and their potential for power generation. The samples presented similar elemental composition and the moisture content for energy generation: 7 % for food scraps (FS), 6 % for cardboard and 4 % for paper. Thermogravimetric analysis were performed to establish that the optimum temperature pyrolysis, in addition to determining  the ash content, values above 20 % may cause loss of energy in the process or soot in the liquid fraction. The lowest  heating value (LHV) presented typical values of biomasses, between 13 MJ/kg and 20/MJ kg. Considering the obtained results, these samples presented energetic potential for use in the pyrolysis process

Executive Functions, Motor Development, and Digital Games Applied to Elementary School Children: A Systematic Mapping Study

Studies show that executive functions and motor development are associated with each other and with learning ability. A more technological lifestyle combined with digital culture should be considered a viable alternative to stimulate children’s development. Therefore, this study aimed to present a systematic mapping of the literature involving executive functions, motor development, and the use of digital games in intervention programs for elementary school children from 6 to 11 years old. Four databases were researched: PubMed, Scielo, Science Direct, and SCOPUS, including publications between 2012 and March 2021. The initial results indicated 4881 records. After the selection process, 15 manuscripts that presented the central theme of the study were selected. The main results indicated that intervention strategies are rather heterogeneous. Most of the studies demonstrated efficient results after intervention protocols, many of them were conducted in Europe, and 46% occurred in a school environment. No research was identified involving technological solutions using executive functions, motor development, and digital games in an integrated manner. Hence, this constitutes a field of future scientific research.N/

Sobre la reforma tributaria estructural que se requiere en Colombia

This article examines the characteristics of an equitable and structural tax reform. Taxation does not only determine revenue, but it also affects the productive apparatus and equitability. In Colombia, tax pressure is very low and resources are insufficient to provide essential public goods. The duty system should contribute to the consolidation of a “new economy”, as it is called by the government, which boosts industry, agriculture, and tourism, and which is less dependent on fossil fuels. Taxes should favor equitability, and so direct taxation should increase in a progressive manner, with a rate which rises as income increases. The recently passed tax reform improves revenue, but favor neither the new economy nor equitability, since it gave too much weight to V.A.T. and very little weight to income or wealth tax.Este artículo examina las características de una reforma tributaria estructural y equitativa. La tributación no solo determina el recaudo, también incide en el aparato productivo y en la equidad. En Colombia la presión tributaria es muy baja, y los recursos son insuficientes para suministrar bienes públicos esenciales. El sistema impositivo debería contribuir a consolidar una “nueva economía”, como la llama el gobierno, que impulse la industria, la agricultura y el turismo, y dependa menos de los hidrocarburos. Los impuestos deben favorecer la equidad, por ello la tributación directa debería aumentar en forma progresiva, con una tarifa mayor a medida que crece el ingreso. La reforma tributaria recién aprobada mejora el recaudo, pero no favorece la nueva economía ni la equidad, pues dio excesivo peso al iva y muy poco a los impuestos de renta y patrimonio

Em direção a Educação Ubíqua: aprender sempre, em qualquer lugar, com qualquer dispositivo

A computação ubíqua visa atender pró-ativamente às necessidades dos usuários, atuando de forma invisível (background). Este cenário permite o desenvolvimento de ambientes voltados à educação ubíqua, onde a mobilidade do aprendiz e a percepção dos elementos que estão em seu entorno (contexto) são parte do processo educativo. Esse trabalho apresenta o GlobalEdu, uma infra-estrutura para suporte a processos educacionais direcionado à educação ubíqua. O sistema é composto de Módulos Educacionais e de um Agente Pedagógico, que acompanha o aprendiz, assistindo on processo educacional, independente do dispositivo de acesso. O modelo foi integrado ao ambiente ubíquo LOCAL e os resultados obtidos mostram a viabilidade da proposta
