Fabricação de rodas: uma análise comparativa

In our country, the majority of freight and people by road happens municipal, state and federal. Thus, the heavy vehicles like buses and trucks are the main means of transporting people and cargo. This graduate work aims to study the process of manufacturing wheels for trucks, because we can see the lack of literature on the manufacturing process of wheels and also the importance of the processes used to manufacture wheels, such as lamination, stamping, puckering, machining, welding and painting

Vicentina Aranha de sanatório a parque: histórias e mudanças

This assignment intents to analyze the recover and the research of the cultural legacy identity of Vicentina Aranha Sanatorium to the inhabitants of the city of São José dos Campos-SP. That initiative becomes present through the importancy of the sanatorium to the public health of Vale do Paraíba in the decades between 30 and 70, of the 20th century. Nowadays this place refuges a park, presenting a reexamination of its space, with the possibility of the leisure practice, entertaining and tourism. The Vicentina Aranha Sanatorium Park presents itself conserving a landscape that is able of being inserted in a continuum past-present resignifying ways of appropriation and use. The word patrimony has many meanings and it‟s commonly associated to the set of goods that someone, the society or an entity owns. Transporting in a determinate territory, the patrimony starts to be a set of goods that are in its limits of administrative competency. (BARRETO, 2000). More than this, the cultural-historical patrimony guard a relation of belonging between it and the entity that has it. The Vicentina Aranha Sanatorium was inaugurated in 1924, with the project of the architect, Ramos de Azevedo, constituting an architectural ensemble placed under governmental trust as a historical and cultural patrimony of the state in 2001. It has a grove with centenary vegetal species like: MOGNO, PEROBA ROSA, JEQUITIBÁ and JACARANDA, constituting also a natural patrimony important for the city. There are projects like “Leitura no Bosque” and it‟s visited by the local population. Today the city seeks a new identity for that place transforming it in the center of industrial and technologic study

Plano de gerenciamento sustentável dos resíduos de construção civil. O caso de Rio Claro (SP)

The current problematic of the construction and demolition (C&D) waste faced for the Brazilian cities, is one of the main degradation factors of the environment, over all about the promise of the urban ambient quality. This scenery must mainly to the unsustainable management adopted by the great majority of the Brazilian cities. Therefore, this work aims at to offer subsidies for medium cities, having as study object the city of Rio Claro-SP, (Brazil), in the elaboration of plans and integrated programs of sustainable management of the construction and demolition waste, in accordance with CONAMA Resolution nº 307/2002, that’s set up a sustainable management system of C&D waste. In this direction, the diagnosis of the management was elaborated for the city of Rio Claro, (generation, collects, transport and disposal) and the public administration of the construction and demolition waste, as well as of the study of the related aspects with C&D waste recycling plant. Later, was suggested a plan of improvements for the public manager of C&D waste: areas of temporary disposal to facility the appropriating destination, appropriated areas of final disposal, incentives to the recycling of C&D waste, new legislations, education and orientation programs and adequacy the agents of C&D waste management (generating, transporting, addressee and public manager), directing for an environmental, economic and social sustainability.

Escoamento da produção de café: uma projeção de logística

This paper seeks to show which impacts there are of the combined use of different modal for the coffee’s outflow. Nowadays is used, almost exclusively, the roadway to transport. How-ever, for this product with low added value, the types of transports best suited, in the litera-ture, are the railway and waterway. For this, is describe the development and spread of coffee throughout Brazil. Subsequently, is calculate the current cost of transporting two producing regions (Minas Gerais and Rondônia), using for that information about the freight, the social cost, and the level of losses along the way. After that is projected costs if utilizes the multi-modal model, when considering the same cost parameters used for the current model. Here-after, an analysis is made of the obtained cost, speed, consistency, capacity, availability and frequency of each transport model. Therefore, note that the multi-modal system is more ef-ficient and economical than current, based on transport by road

Antidepressivo modula o comportamento e a expressão gênica das cadeias de miosina, serca2 e fosfolambam em ratos com insuficiência aórtica?

Introduction: Aortic insufficiency (AoI), a volume overload, is characterized by the diastolic reflux of blood from the regurgitating aorta to the left ventricle. This effect results from malfunctioning aortic cusps. The main cause of AoI in developing countries is rheumatic fever, including Brazil, and valvar degeneration in developed countries. There is a strong association between cardiovascular diseases and depression. Selective serotonin reuptake inhibitors (SSRI) are one of the most prescribed antidepressants in the world. Previous studies of our laboratory showed that the utilization of a SSRI, paroxetine, improved cardiac function in rats with sub-chronic AoI and reduced the daily ingestion of hypertonic sodium (NaCl 0,3M). Cardiovascular diseases can determine behavior changes like increase of anxiety, and it is yet unknown if AoI would determine anxiety or anhedonia, incapacity of obtaining pleasure through physical or sensorial experiences. A possible target for SSRI action could be a change in the expression of enzyme isoforms that collaborate in the contractile function of the heart muscle, like the heavy chains of myosine, the sarcoplasmatic reticulum Ca2+/ATPase (SERCA) and its regulator protein, phospholamban (PLB). Objectives: Evaluation of behavior parameters for anxiety and anhedonia state and genic expression of a-myosine, b-myosine, SERCA2a and PLB in the heart tissue of rats with subchronic AoI that received treatment with an SSRI (paroxetine) for 4 weeks. Methods: Surgery to induce AoI was performed on male Wistar rats, anxiety was evaluated by the elevated plus-maze (EPM) and state of anhedonia was tested by ingestion of 2% sucrose solution. After euthanasia the heart tissue was collected and total RNA was extracted to be analyzed by the RT-qPCR method. Results: Heart fractional shortening was preserved in rats with AoI that were treated compared to rats with AoI that were not treated. There was no statistically ...

Histochemistry profile of the biceps brachii muscle fibres of capuchin monkeys (Cebus apella, Linnaeus, 1758)

A general analysis of the behaviour of "Cebus" shows that when this primate moves position to feed or perform another activity, it presents different ways of locomotion. This information shows that the brachial biceps muscle of this animal is frequently used in their locomotion activities, but it should also be remembered that this muscle is also used for other development activities like hiding, searching for objects, searching out in the woods, and digging in the soil. Considering the above, it was decided to research the histoenzimologic characteristics of the brachial biceps muscle to observe whether it is better adpted to postural or phasic function. To that end, samples were taken from the superficial and deep regions, the inserts proximal (medial and lateral) and distal brachial biceps six capuchin monkeys male and adult, which were subjected to the reactions of m-ATPase, NADH-Tr. Based on the results of these reactions fibres were classified as in Fast Twitch Glycolitic (FG), Fast Twitch Oxidative Glycolitic (FOG) and Slow Twitc (SO). In general, the results, considering the muscle as a whole, show a trend of frequency FOG>FG>SO. The data on the frequency were studied on three superficial regions FOG=FG>SO; the deep regions of the inserts proximal FOG=FG=SO and inserting the distal FOG>FG=SO. In conclusion, the biceps brachii of the capuchin monkey is well adapted for both postural and phasic activities.

Removal of clay by stingless bees: load size and moisture selection

Some organisms disperse energy, associated with the transportation of resource, which is not necessarily food. Stingless bees of Central Amazonia (Melipona flavolineata and M. lateralis) collect clay in banks along streams for nest building. The moisture of the clay varies along the bank, and bees collect clay from specific location, indicating that there is some sort of preference regarding their selection. This study aims at identifying: if larger bees carry more clay; if there is a preference for moisture of substrates; and if bees are less efficient accumulating and transporting clay when it is wet. In order to do so, I measured the size of the bees and of the pellets of clay found in the corbicula. I set up a field experiment to test substrate preferences. The amount of clay transported, increased exponentially in accordance to the size of the bee, and the preferred substrate was the driest clay. The amount and the efficiency of removal of clay were not affected by the moisture of the substrate. Despite the wet clay being denser, it does not reduce the efficiency of exploitation of the resource, but suggests that bees spend more energy to carry the same quantity of wet clay, which may be the underlying mechanism explaining their preference for removing drier clay.

Aspectos Morfologicos e Histoquimicos de los Musculos Extraoculares del Zorrillo (Didelphis albiventris)

The extraocular muscle fibres of the South-American opossum were determined according to their metabolic profiles using NADH-diaforase, and myofibrilar ATPase after pre-incubation in both acid (pH 4.3) and alkaline (pH 10.4) media. Three muscles were selected to study the arrangement of the fibres (obliquous dorsalis, rectus dorsalis and rectus lateralis muscles). It was demonstrated that they are organized in two layers: the orbital layer composed by small diameter fibres and the global layer with three-times thicker fibres than the former. The global layer has three fibre types: white, red and intermediate; while the orbital layer presents two fibre types, which react differently to the ATPase.
