REVERSE LOGISTICS OF AGROCHEMICAL PESTICIDE PACKAGING AND THE IMPACTS TO THE ENVIRONMENT

Abstract: Over time, agriculture has proven to be an important economic development factor for Brazil. The evolution and the need for productivity caused a large increase in the use of pesticides in agriculture and with it, the need to give proper treatment to packaging. With these agricultural activities in evidence, it is not possible to keep the crops without the use of pesticides. In 2000, it was created the 9,974 law as a decree Law 4,074/2002, which regulates the reverse logistics of empty containers of pesticides. This study intends to demonstrate that there are still producers who have difficulties in finding the correct destination to pesticide containers because of lack of knowledge of the law or because they acquire chemicals illegally, without a specific origin. The instruments for protecting the environment, such as licensing and environmental legislation stand out as high points, since it has the general objective of analyzing and demonstrating how reverse logistics helps minimize the impact and the possible environmental and health problems caused by the incorrect disposal of pesticide containers of and along with a group of farmers

APPLICATION OF THE TOOLS OF PRODUCTION ENGINEERING FOR THE REDUCTION OF DEAD TIME IN AN ASSEMBLY LINE

Abstract: The constant changes in the agricultural equipment market have brought many challenges to the productive sectors inside the organizations. Once the market is increasingly competitive, the industries lack of efficient working methods and companies seek intensely to adapt themselves to a methodology to assist in the standardization of production processes. The main objective of this work is the application of some tools of Production Engineering to improve the operating times in an assembly sector of a metal mechanical industry. The focus is to establish and to define the guidelines of the used methodology, the so-called ‘Just in time’, to seek the reduction of dead time in the process of the assembly line according to the reality of the companies. Change processes are very conditioned to the environment, the culture of who receives them and leads them. Thus, this project also aims to aid in the maturation of the staff in this cultural aspect, seeking the development of operators in a new operating process

The Taxonomic Revolution of New World dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae)

After almost two decades of stagnation, the taxonomy of the New World Scarabaeinae dung beetles has since 1988 been going through a period of great effervescence. In the last 35 years, 81 complete revisions and 69 supplements have been produced by 86 authors based in 15 countries, addressing the taxonomic status of 950 species. This is what we christen as the Taxonomic Revolution of New World dung beetles. We review the history and products of this revolution, explore its causes and its apparent exceptionalism among most other New World Coleoptera groups, and point to the many great challenges that still face the scarabaeine taxonomists. An aspect of interest to ecologists is the coevolution of the Taxonomic Revolution with what we call the Ecological Revolution of dung beetles, i.e., the similar expansion in ecological studies about these organisms. We argue that it has been the continuous feedback between these two simultaneous processes that has enabled each of them to exist and flourish: without the Ecological Revolution, the Taxonomic Revolution could not have existed, and vice-versa. Ecologists and taxonomists are partners in the scientific enterprise, symbionts one may say

On human-in-the-loop CPS in healthcare: a cloud-enabled mobility assistance service

Despite recent advancements on cloud-enabled and human-in-the-loop cyber-physical systems, there is still a lack of understanding of how infrastructure-related quality of service (QoS) issues affect user-perceived quality of experience (QoE). This work presents a pilot experiment over a cloud-enabled mobility assistive device providing a guidance service and investigates the relationship between QoS and QoE in such a system. In our pilot experiment, we employed the CloudWalker, a system linking smart walkers and cloud platforms, to physically interact with users. Different QoS conditions were emulated to represent an architecture in which control algorithms are performed remotely. Results point out that users report satisfactory interaction with the system even under unfavorable QoS conditions. We also found statistically significant data linking QoE degradation to poor QoS conditions. We finalize discussing the interplay between QoS requirements, the human-in-the-loop effect, and the perceived QoE in healthcare applications

Aplicação da metodologia 5s em um laboratório de fisiologia de peixes da Universidade Federal de Santa Maria

As estratégias da Gestão da Qualidade invariavelmente visam ao envolvimento da mão-de-obra no esforço para produzir qualidade em processos, produtos e serviços. O Programa 5S criado no Japão na década de 1950, surgiu como um modelo prático para o combate às causas de perdas, desperdícios e organização do ambiente de trabalho. Porém, para esta organização acontecer, é necessário o envolvimento e ação do grupo de funcionários diante da inegável importância dos recursos humanos para a competitividade da organização. Já de comprovada eficiência e eficácia, ao longo dos anos, o Programa 5S se destaca como uma das ferramentas da qualidade mais importantes na busca da educação, treinamento, qualificação profissional, capacidade intelectual e disciplina no ambiente das organizações. O presente estudo foi desenvolvido em um laboratório de fisiologia de peixes da Universidade Federal de Santa Maria. O objetivo do estudo foi implementar o Programa 5S visando melhorias no laboratório a fim de otimizar a organização, tempo e espaço. Foram realizados sete encontros ao longo de 32 dias com a equipe do laboratório para a implementação das cinco etapas do programa. Como resultado, após a implementação do programa as melhorias foram facilmente identificadas. Ambiente mais organizado, mais limpo, aumento do espaço útil, otimização do tempo na busca de materiais e melhoria na iluminação foram alguns dos benefícios alcançados com a implementação do Programa 5S no laboratório estudado

Aerobic exercise attenuates inhibitory avoidance memory deficit induced by paradoxical sleep deprivation in rats

The deleterious effects of paradoxical sleep deprivation (SD) on memory processes are well documented. Physical exercise improves many aspects of brain functions and induces neuroprotection. in the present study, we investigated the influence of 4 weeks of treadmill aerobic exercise on both long-term memory and the expression of synaptic proteins (GAP-43, synapsin I, synaptophysin, and PSD-95) in normal and sleep-deprived rats. Adult Wistar rats were subjected to 4 weeks of treadmill exercise training for 35 min, five times per week. Twenty-four hours after the last exercise session, the rats were sleep-deprived for 96 h using the modified multiple platform method. To assess memory after SD, all animals underwent training for the inhibitory avoidance task and were tested 24 h later. the aerobic exercise attenuated the long-term memory deficit induced by 96 h of paradoxical SD. Western blot analysis of the hippocampus revealed increased levels of GAP-43 in exercised rats. However, the expression of synapsin I, synaptophysin, and PSD-95 was not modified by either exercise or SD. Our results suggest that an aerobic exercise program can attenuate the deleterious effects of SD on long-term memory and that this effect is not directly related to changes in the expression of the pre- and post-synaptic proteins analyzed in the study.

A importância de estratégias bioclimáticas aplicadas no projeto arquitetônico

Bioclimatic architecture can be defined as an architecture that brings, in its essence, the climate as an important variable in the design process. Through the use of bioclimatic structures, it is always possible, in a natural way, comfort conditions for the building and consequently for its users, reducing energy consumption. Facing these aspects, the main objective of this work is to identify bioclimatic strategies employed in a building in the city of Itaara, central region of Rio Grande do Sul state, Brazil, based on a climatic characterization of the site and study of the guidelines indicated by the Brazilian standard of comfort , NBR 15220-3. No study has been demonstrated that the implantation of the underground air tunnel and a construction of internal ducts with the objective of producing a crusade added to the placement of double walls and double glazing are the main constructive elements in the model of using bioclimatic strategies. On days when the external temperature exceeds 35ºC, the internal environments of the building are around 25ºC, with the use of ventilation coming from the wind tunnel, showing the efficiency test of bioclimatic technologies.A arquitetura bioclimática pode ser definida como uma arquitetura que traz, na sua essência, o clima como uma variável importante no processo projetual. Por intermédio do uso de estratégias bioclimáticas, é possível obter, de forma natural, condições de conforto para o edifício e consequentemente para seus usuários, reduzindo o consumo de energia. Diante desses aspectos, o objetivo principal deste trabalho foi identificar estratégias bioclimáticas empregadas em uma edificação na cidade de Itaara, região central do Estado do Rio Grande do Sul, Brasil, tendo como base a caracterização climática do local e o estudo das diretrizes indicadas pela norma brasileira de conforto, NBR 15220-3. Ficou demonstrado no estudo que a implantação do túnel de ar no subsolo e a construção de dutos internos com objetivo de proporcionar ventilação cruzada, somadas à colocação de paredes duplas e vidros duplos, são os elementos construtivos principais no modelo de utilização das estratégias bioclimáticas. Em dias em que a temperatura externa passa dos 35 ºC, os ambientes internos da edificação apresentam temperatura em torno dos 25 ºC com o uso da ventilação oriunda do túnel de vento, demostrando a eficiência do uso das estratégias bioclimáticas
