13. Y-shaped and fruiting wall peach orchard training system in subtropical Brazil
ASBTRACT Peach as commercial crop in Brazil is usually grown in open vase training system. However, in the 1970s large orchards changed to the Y-shaped system and higher density of plants. This system is the most used in São Paulo state because it allows orchard densification. However, the longevity of the trees is reduced from 15 to 8 years being the exces

14. FINANCIAL ANALYSIS OF ENRICHMENT MODEL USING TIMBER AND NON-TIMBER PRODUCTS OF SECONDARY REMNANTS IN THE ATLANTIC FOREST
RESUMO Os aspectos socioeconômicos podem limitar a expansão da restauração ecológica. Uma alternativa para esta questão é o desenvolvimento de modelos que geram renda para os agricultores, além dos ganhos da própria conservação. Projetamos e implementamos a iniciativa "Sustenta A Mata", um projeto desenvolvido pela The Nature Conservancy e apoiado

15. Appliance of a high pressure semi-batch reactor: supercritical transesterification of soybean oil using methanol
Abstract This work presents the results of a supercritical transesterification process of soybean oil using methanol, performed in a laboratory high pressure semi-batch reactor. A full description of the equipment and a standard operating procedure are also provided. Since fossil fuels are not renewable, biofuels such biodiesel, have gained attention over t

16. Characterization of the Physicochemical Properties of Different Biodiesel Samples
ABSTRACT For combustion engines to perform well, it is necessary that the fuel used be of high quality. Fuel quality can be analyzed through different physicochemical properties. This study presents comparisons between the values presented in literature, legislation and those obtained through experimental tests of different biodiesel samples. Biodiesel is a

17. Characterization of grid-connected photovoltaic systems in Curitiba, Brazil
ABSTRACT In the search for new options for the establishment of the energy matrix of Brazil, the Grid-Connected Photovoltaic Systems (GCPVS) are configured as an alternative to urban centers, because they allow the power generation at distributed mode, that is, generate energy at the place where it will be consumed and inject the surplus energy into the netw

18. New concept of tunnel boring machine: high performance using water jet and diamond wire as rock cutting technology
Abstract Tunnel boring machines are important tools in underground infrastructure projects. Although being well established equipment, these machinesare based on designsof more than 60 years ago and are characterized by big dimensions, enormous weight and high power consumption. Commercial aspects should be noted too. The model adopted by the TBM industry re

19. Optimizing suction blister epidermal graft technique in the surgical treatment of vitiligo
Abstract: Surgical management of vitiligo is considered an excellent terapeutic option for recalcitrant cases, provided the disease is stable and there is absence of Koebner phenomenom. Among surgical modalities, Suction Blister Epidermal Graft is a low cost and effective option (65 to 100% repigmentation can be achieved in up to 80% of patients). We describ

20. Novel immunoassay for TSH measurement in rats
ABSTRACT Measuring thyroid hormones is an important aspect for the study of metabolism and for monitoring diseases in both human and animal models. The traditional method for hormone measurement in rats is the radioimmunoassay (RIA). However, the RIA is associated with some practical disadvantages, including the use of radioactive material, the need for spec

21. OPTIMIZATION MODEL FOR VEHICLE ROUTING AND EQUIPMENT REPLACEMENT IN FARM MACHINERY
ABSTRACT: An equipment replacement decision takes into account economic engineering models based on discounted cash flow (DCF) such as the Annual Equivalent Cost (AEC). Despite a large number of researches on industrial assets replacement, there is a lack of studies applied to farm goods. This study aimed at assessing an alternative model for economic decisi

22. Simulation of the Mineração Serra Grande Industrial Grinding Circuit
Abstract Increasing throughput during the mining cycle operation frequently generates significant capital gains for a company. However, it is necessary to evaluate plant capacity and expand it for obtaining the required throughput increase. Therefore, studies including different scenarios, installation of new equipment and/or optimization of existing ones ar

24. Analysis of options of production and access ways in underground mines
Abstract This article aims to review the issues to be considered in choosing primary access and transportation options for underground mines. The main accesses to underground orebodies are declines or vertical shafts. They serve both as a way to transport ore or waste, and move people, equipment or supplies. In underground mines, the ore transport option sig
