Fases de investigação geológico-geotécnica para a implantação de dutovias

The research addresses the need for detailed geological and geotechnical investigations in pipeline’s design, given the diversity of geological units crossed by these works along its layout, which often extends for hundreds of miles. For its large size, this type of work often goes through different states and regions with very different characteristics in terms of topography, vegetation, geology and geotechnical conditions. For a better use of these investigations in order to avoid unnecessary costs and inefficient results, some authors recommend that steps be taken to study, seeking a progressive detail of the pipeline’s implantation area. The main objective of the study is to describe, analyze and correlate the proposals for geological and geotechnical’s investigation recommended by the authors selected. Nogueira Junior & Marques (1998) suggest that for better effectiveness of geological and geotechnical investigations associated with the deployment of pipelines, different research methods are applied sequentially in five major stages of the building. Rocha et al (2008) recommend that, for the pipeline’s implantation using horizontal directional drilling, investigations are performed in three phases of study, to be developed in coordination with the project stages. For Gelinas & Mathy (2004), when time and budget constraints permit, geotechnical investigations for directional drilling projects for pipelines must be made in four sequential phases. Heinz (2008) suggests that the geotechnical investigations for pipeline’s implantation using horizontal directional drilling at crossings of water bodies are carried out in three successive stages. By the development of research, we could see that all the different proposals recommend studies in sequential phases, starting from a more general scale for a more specific, seeking a progressive understanding of the geological model of the area where you intend to deploy the pipeline

MiLoc-Sys Mobile: gestão em locação

Companies that invest in current technologies maintain themselves updated, improve their business rules and anticipate themselves against rivals providing a better service to their customers. This project aims to develop an ERP - Enterprise Resource Planning module for Android which complements an existing manager system and, that attends the needs of a rental equipment business for civil building, i.e., it improves the communication channel company-client and betters the identification and control of products. During the developing of this project, it was necessary to study the company business rules, analyze the requirements and the appropriate technologies. This project was organized in two parts, contemplating e ach of these needs. It were implemented specific modules for generate budgets and pre-orders in the first part and, the use of radiofrequency tags in the second one. Thus, it was possible to assign mobility to company business rules so that a better rental service can be provided and the equipments can be better managed

Estudo do aumento no diâmetro do corpo de um rebite a ser cravado em furos acima da tolerância de projeto

In this work are discussed the main types of rivets, their characteristics and applicability within the Aeronautical Industry branch. Here are highlighted the solid rivets, showing off its layout, forms and limits of installation, that are required by aviation regulators. The riveting is a popular and simple procedure of fixing and joining two or more parts, and like any other manufacturing process is subject to process deviations that in some situations are beyond the limits of tolerance. One of these deviations is when the hole diameter exceeds the one proposed in project and which is limited by the rule of edge distance. The overall objective here is to study a possible solution to this problem: the installation of a rivet that has his diameter previously increased by compression. Observe the hole filling after riveting, detect the presence of cracks, discover the yield curve of the fasteners and their the crushing limits for failure prediction are tools used to verify this proposal. They demonstrate, at the end of study, the inefficiency of this procedure, with results that go against the safe fixing of parts in a structure

Projeto e análise de um sistema de ancoragem para um motor foguete a combustível líquido

This work aims the design and analysis of a thrust frame system for a liquid fuel rocket engine. The project was developed following the design requirements established by the Division of Space Propulsion of the Institute of Aeronautics and Space. The layout of the structure was developed with the aid of a software of 3D modeling and static and dynamic analysis were performed by using a finite element package. The results of the analyzes helped in defining the layout of the structure which met all design requirements. The safety factor and the mass achieved were comfortably low, which may be useful in the future because the liquid fuel rocket engine is still in development

Considerações sobre o uso do piercing lingual

Objective: Investigated the consequences of tongue piercing in individuals from the city of Araraquara, São Paulo, Brazil. Methods: In Araraquara there are five piercing shops, but only two agreed to help the research by providing the contact information of customers who had had their tongues pierced. These customers were contacted by telephone. By the end of the research, the sample consisted of 100 individuals from both genders aged 18 years or more. Not all of them still had their tongue piercing. A form with six objective questions was used to collect information. The information was then analyzed by descriptive statistics. Results: From the 100 participants, 77 had been using tongue piercing for more than 6 months. It took less than 4 months for the tongue to heal. Sixty–eight individuals used oral rinses and of these, 19 also used painkillers. Only 11 individuals did not present symptoms after the first weeks using the piercing. On the other hand, 56 individuals reported complications such as increased salivation, speaking difficulties, gingival or mucosal traumas, dental fractures and eating difficulties. Conclusion: All these tongue-piercing complications justify efforts to inform the youth about the use of piercing in the oral cavity.

Tendência de crescimento facial em ortodontia e ortopedia funcional dos maxilares

The knowledge of the facial growth trend is very important in orthodontic treatment. A lateral headfilm is recommended in all young patients undergoing a preorthodontic guidance program to anticipate the best time to begin any mechanical procedures and the possibilities to determine the type of facial growth trend. In type A it will be observed that the middle and lower face are growing forward and downward in unison, with no change in ANB angle. Type B growth trends reveals that growth is downward and forward, with the middle face growing forward more rapidly than the lower and in type C the lower face is growing downward and forward more rapidly than the middle face revealing a decrease in the size of the ANB angle.

Non-nutritive sucking associated with self-mutilating behavior

Although sucking activity has been considered an essential behavior of early childhood to satisfy nutritive and non-nutritive needs, digit and pacifier sucking are deleterious oral habits that may interfere with child development. Furthermore, this clinical picture may be compounded by other concerning habits, such as self-mutilating behavior. This article reports 4-year follow-up of a child in whom non-nutritive sucking was associated with an unusual self-mutilating behavior; namely, the child would pull out her own hair after wrapping it around her finger every time she sucked on the pacifier. This occurred specially at bedtime, while she was watching TV, or when she was somewhat anxious, and remitted and recurred throughout the follow-up period. In an attempt to address this behavior, pacifier use was discontinued and the child’s head was shaved. Ultimately, the case was only solved through combined efforts involving the child, her family, and health professionals. Based on the parents’ reports and clinical examination and follow-up findings, we emphasize the importance of investigating the origin of the problem and considering emotional aspects and its association with other habits in such cases.

Redução do medo durante o tratamento odontológico utilizando pontas ultrassônicas

Over the last few years, new technologies have been developed to making cavity preparations, among which the diamond burs CVDentus® (CVDentus, São José dos Campos, Brazil) are outstanding. These points are produced by chemical deposition from the vapor phase, forming a single diamond stone, with greater durability than the conventional diamond burs. Coupled to the ultrasound appliance, they have several clinical applications in Dentistry with advantages over conventional rotary instruments, such as lower pressure, noise, vibration and heat, as well as reducing the need to use local anesthesia, contributing to minimize patient’s fear and anxiety. The aim of this study was to present the complete restorative dental treatment performed with this system in a child patient with a prior history of non-cooperative behavior. The use of this new technology offered the patient greater comfort, making it possible recondition the patient’s attitude to dental treatment, in addition to favoring conservative cavity preparations to be made.
