Manejo de Irrigação para Otimização do Rendimento e Qualidade de Frutos de Tomateiro em Sistema de Plantio Direto

Existem muitas informações sobre o potencial matricial de água no solo adequado para o reinício de rega em sistema de plantio convencional, mas há poucas informações sobre qual o melhor potencial da água do solo para o controle da irrigação em sistema de plantio direto (SPD). Dessa forma, objetivou-se estudar o efeito de cinco de níveis de irrigação sobre a produtividade, o teor de sólidos solúveis e a acidez em frutos do tomateiro para processamento, cultivar Hypeel, cultivado no SPD em Latossolo Amarelo. O experimento foi conduzido sob delineamento experimental em blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos consistiram de cinco valores de potencial matricial de água no solo para reinício da irrigação (m a 13 cm de profundidade medido por tensiômetros): -15 kPa, -30 kPa, -45 kPa, -60 kPa e -75 kPa. A produtividade máxima foi obtida quando o valor de tensão da água do solo esteve em -28,5 kPa. O teor máximo de sólidos solúveis foi obtido quando o valor de tensão da água do solo alcançou valores em torno de -50,8 kPa.

Da escassez ao estresse do planeta: um século de mudanças no ciclo do nitrogênio

Heavy metals and pesticides are usually associated with the main problems humankind has created in the natural environment. However, compounds with characteristics of essential macronutrients are causing serious environmental changes that could intensify, compromising the diversity of life on the planet. This is the case of nitrogen compounds, produced by industrial processes for use in intensive agriculture in addition to those unwittingly produced from human activities, available in excess in the environment. These compounds warrant greater attention from researchers in various fields of knowledge and public agencies for environmental control, toward minimizing their availability in the environment, thereby returning conditions closer to the natural environmental balance of the planet.

An emergy-based evaluation of a reverse logistics network for steel recycling

Efficient implementation of recycling networks requires appropriate logistical structures for managing the reverse flow of materials from users to producers. The steel sheet distributor studied had established a protocol for scrap recovery with the steel plant and its customers. The company invested in producing containers, hiring a specialized labor force and in purchasing trucks for container transportation to implement the logistics network for recycling. That network interconnected the company with two kinds of customers: the ones returning scrap and the ones who preferred to continue business-as-usual. The logistical network was analyzed using emergy synthesis, and the data obtained were used to evaluate and compare the system's environmental costs and benefits from the perspective of the distributor and the steel plant operator. The use of emergy ternary diagrams provided a way to assess recycle strategies to compare the relative economic and environmental benefits of the logistical network implemented. The minimum quantity of scrap that the distributor must recover to improve environmental benefits was determined allowing decision on whether it is worth keeping the system running. The new assessment method proposed also may help policy-makers to create strategies to reward or incentive users of reverse logistics, and help to establish regulations, by decreasing taxes or stimulating innovation, for effectively implement the National Policy on Solid Waste.

Aplicação de princípios do pensamento enxuto no processo de envio e devolução de correspondências em um banco privado

The success obtained by the Toyota Company in implementing the Toyota Production System was a global case of study that generated different new approaches, such as Lean Thinking. This approach was already successfully applied to various sectors, breeding methodologies as Lean Service, Lean Office or Lean IT. In this paper, the main concepts of Lean Thinking were applied in an information flow through an action research, more specifically in the sending and return of mailing process from a bank. The objectives were to create changes that led to the decrease of the mail returning indexes and ultimately to cost reduction and waste elimination. For this purpose the actual situation was mapped, and after data collection and analysis, a future proposed state was generated for the information flow. Alongside, indicators were conceived for managing process control and a set of implemented and proposed improvements were delivered. The applied Lean Thinking concepts were considered efficient for the application, and the proposed objectives were achieved

Orientação espacial em pessoas com deficiência visual: um estudo de triangulação por meio de monitoramento remoto

This study was conducted to investigate how visually impaired people perform distance estimation tasks by movement and navigation during deprivation of effective perceptual and proprioceptive information. For that they performed the task of walking three distances, being the first and second of 100 meters and the third of 140 meters (triangulation) from a point of origin in open field on a inverted L shaped trajectory and then returning to the origin. The first and second tasks were driven by means of a guide with GPS adapted to the study coordinates, and the third one was freeform with three sessions, the first without perceptual and proprioceptive restrictions, the second without auditory perception, and the third in a wheelchair, without proprioception. The objective of this study was to indicate the differences in distance reproduction in relation to accuracy and investigate the spatial representation of participants in a navigation task, in which there is active movement, but no effective perceptual and proprioceptive information. Results showed that the average participants underestimated distances producing average angles close to the value of 45°. And by means of the "t" students test no significant differences between subjects can be pointed out. To achieve these results we used remote monitoring by GPS and software TrackMaker.

Treatment and complications of orbito-zygomatic fractures

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.
