O problema da motivação moral em Kant

Por que os homens são livres? No que consiste a liberdade humana? Como é possível a ação moral? Como um corpo submetido a leis naturais pode ser livre? Para responder perguntas simples como estas e outras não tão simples é que Hélio José dos Santos Souza se dedica a estudar a obra de Kant, especialmente a Fundamentação da metafísica dos costumes. Trata-se de saber se a moralidade e a ética são expressões de um princípio racional incondicionado igualmente presente nas leis imutáveis da natureza, e como é possível nos tornarmos homens melhores apesar de sermos homens. O autor apresenta ainda a discussão destes problemas por alguns dos grandes intérpretes da obra de Kant, o que enriquece filosoficamente a análise e as alternativas pertinentes. Este é um trabalho acadêmico que pode estabelecer a vocação filosófica de seus leitores: a reflexão sobre o que está em jogo é por si só um prazeroso exercício do filosofar

O problema do financiamento: uma análise histórica sobre o crédito no complexo cafeeiro paulista. Casa Branca (1874-1914)

A principal proposta desta obra é analisar as formas como a cafeicultura foi financiada na cidade paulista de Casa Branca durante um período de pleno desenvolvimento dessa cultura - final do século 19 e começo do 20 -, e as relações entre a acumulação de capitais nesse setor agrícola e a urbanização do município. O autor ampara-se em pesquisas da história econômica, baseadas nas relações que fundamentam a economia, e em áreas como a cultura e a política. Além disso, aproveita fontes documentais ainda pouco sistematizadas, como dívidas hipotecárias e penhores agrícolas, registrados em Livros Cartoriais. A obra explica como as elites ligadas à cafeicultura da região de Casa Branca centralizaram volumes consideráveis de capitais, e os investiram em grandes cidades, inclusive deixando de pagar os devidos impostos municipais. O autor estabelece um quadro da economia regional e local, com o objetivo de apreender o processo pelo qual se impediu que os recursos financeiros gerados na economia agrária de exportação se fixassem localmente. Para o professor Pedro Geraldo Tosi, que assina o prefácio, a obra é um convite aos que se interessam pela expansão e pelos desdobramentos da cultura do café e, também, os que pretendem entender melhor a importância que tiveram as cidades do interior para configuração de uma das mais instigantes metrópoles do mundo: São Paulo.

Dretske e o problema dos qualia

The aim of this paper is to present and discuss Fred Dretske's (1995) suggestion for analysis of the problem of qualia. Such a problem was acknowledged following Thomas Nagel's discussion in his classical paper What is it like to be a bat. In the paper, Nagel (1974) postulates the impossibility of knowing aspects of human experience from a third-person perspective. He considers that qualitative aspects of a subject's experience, fundamental for characterization of qualia, would be lost during the course of objective descriptions of it. Based on his Representational Thesis of Mind, Dretske argues that if we were to consider mind to be the representational aspect of the brain, the nature of qualia would thus be representational. In this context, mental facts related to experiences would be representational facts: if we were to know the nature of these representational facts, we would also know the experience the system represents. Given this understanding, we discuss to what extent the Dretskean proposal constitutes (or not) an alternative for the problem of qualia.

Transportador de correia: componentes e cálculos básicos para seu dimensionamento

Increasingly, people searches for an efficient and economic way for transporting bulk materials. Transport through belts is now the most widely used mean for transporting bulk materials, used by companies from various sectors such as mining, quarrying, agribusiness, etc. There are many advantages of using a conveyor belt as compared to rail or by truck. Trucks needs a driver, have a high risk of accidents as well as a high cost for maintenance and as well as trains, after making the downloading of the material, return empty to the next load. The cost for the construction of a railway is very high, making it often impossible. The conveyor belt have a high cost of installation, but it works 24 hours a day, 365 days a year. The upper side of the belt is always loaded, the maintenance cost is average and the risk of accidents is low, causing it to be the ideal way to transport bulk materials. This monography aims to interest the reader about what is a conveyor belt, what are its main components and demonstrate the basic calculations for their sizing and selection of components. Throughout the work, scaled a belt conveyor for use in the mining sector, but the concepts demonstrated apply to the transport of any material

Utilização de água pluvial para fins não potáveis: análise do atendimento da demanda pelo método de eficiências para dimensionamento de reservatório para diferentes regimes pluviométricos brasileiros

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

Dimensionamento de suspensões veiculares para isolamento de vibrações excitadas pela via

This work intends to perform the dimensioning of the Guaratinguetá’s Engineering College Baja SAE vehicle suspension system. To do so, concepts of suspension systems, human comfort limits to vibrations and automotive models for suspension vibration analyses are reviewed. On the development of this work descriptions of considerations specific for the vehicle object of this work are made as well as descriptions of the experiment made to determine the stiffness of the tire used. These concepts are applied through a computational routine that allows the dimensioning of springs and shock absorbers of both front and rear axles of a vehicle in a way to respect all the criteria showed during this work and visualize the system’s behavior when excited on different frequencies

Projeto de conjunto redutor de velocidade utilizando engrenagem sem-fim

This work is initially based in give a solution to a problem consisting of lifting a load in a warehouse focusing specifically on the solution´s project and comparison of the results obtained following the sequence of the book and comparing these results with the finite elements simulation based on the 3D components modeling. Starting from that was realized the project of the worm gear reducer to solve the problem and makes the work easier. The project consisted basically of the study, project itself and simulation by software of a worm gear reducer and projects steps, starting with the initial problem conditions (to lifting a load up to an specific height at a given time) following all the reducer project sequence, starting by the preliminary draft and electric motor selection using iterative process, material selection, worm gear dimensioning, axles, keyways, bearings and coupling. After that was performed the three dimensional modeling of the components using SolidWorks software and simulating these components using Ansys software. The results show the importance of the CAD in terms of improving project development speed and reducing costs with prototypes
