1. ROTAXANOS - INTERAÇÕES INTERCOMPONENTES E MOVIMENTOS MOLECULARES
Rotaxanes are currently one of the most promising objects of study in the field of artificial molecular machines. A rotaxane molecule is composed by two or more molecular components that are connected by a mechanical bond. 51 years ago, the first synthesis of this type of molecules was performed, since then, there has been a great effort in obtaining new mod

2. SOCCER CLEATS WITH BLADE-SHAPED STUDS AND MECHANICAL OVERLOAD IN SOCCER: A SYSTEMATIC REVIEW
RESUMO As chuteiras com travas em forma de lâmina promovem uma alta tração no gramado, podendo ser benéficas para o desempenho no futebol. Por outro lado, movimentos com rápidas mudanças de direção associados com tração alta das chuteiras podem aumentar a sobrecarga e as chances de lesão. Diante da falta de consenso sobre os efeitos dessas chuteir

3. A new technique for tongue brushing and halitosis reduction: the X technique
Abstract The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor. Objective: To evaluate a new tongue hygiene technique hereby referred to as “the X technique” and its effects on both halitosis and the number of microorganisms based on microbiological parameters and diagnostic

5. Advances and perspectives of mechanomyography
INTRODUCTION: The evaluation of muscular tissue condition can be accomplished with mechanomyography (MMG), a technique that registers intramuscular mechanical waves produced during a fiber's contraction and stretching that are sensed or interfaced on the skin surface. OBJECTIVE: Considering the scope of MMG measurements and recent advances involving the tech

6. Desenvolvimento e caracterização de dispositivo de PLLA/Trietil-Citrato associado à derme suína acelular para reparação de lesões cutâneas / Development and characterization of PLLA/Triethyl citrate device associated to acellular dermal matrix to repair cutanous wounds
One of the challenges of the Tissue Engineering is to promote a better functioning of organs and tissues damaged by diseases or traumas. With target for developing a biphasic device for future regeneration and dermal application in Tissue Engineering and Regenerative Medicine, fibroblasts from VERO cell line were cultivated on a porcine acellular dermal matr

7. COMPORTAMENTO DE TALUDE DA MARGEM DO RIO SÃO FRANCISCO SUBMETIDO À TECNICA DE BIOENGENHARIA DE SOLOS. / BEHAVIOR OF THE SLOPE OF THE SÃO FRANCISCO RIVER SUBJECTED TO THE SOIL BIOENGINEERING TECHNIQUE.
The lower San Francisco river had changed their hidrossedimentological behavior by changes in river channel through the impoundment of water reservoirs for the implementation of large hydropower projects. These direct impact on the stability of river banks, demands actions to mitigate the erosion resulting from soil mass movements. Soil bioengineering, which

8. Biomechanical in vitro evaluation of three stable internal fixation techniques used in sagittal osteotomy of the mandibular ramus: a study in sheep mandibles
Among the osteotomies performed in orthognathic surgery, the sagittal osteotomy of the mandibular ramus (SOMR) is the most common, allowing a great range of movements and stable internal fixation (SIF), therefore eliminating the need of maxillomandibular block in the postoperative period. OBJECTIVES: The purpose of this study was to evaluate the biomechanica

9. Evaluation of the mechanical behaviour of different devices for canine retraction
OBJECTIVE: To mechanically evaluate different systems used for canine retraction. METHODS: Three different methods for partial canine retraction were evaluated: retraction with elastic chain directly attached to bracket; elastic chain connected to bracket hook and with sliding jig activated with the aid of an elastic chain attached to a mini-implant. For thi

10. Estratégia terapêutica após contusão da medula espinhal: recuperação funcional e estabilidade cortical sensório-motora / Therapeutic strategy after spinal cord contusion: functional recovery and sensorimotor cortical stability
Spinal cord injury (SCI) results in a devastating condition, which leads to motor and sensory deficits that impair the injured person functional performance. Spinal cord injury experimental models are used in sensory-motor functioning and reorganization or plasticity promoted by trainings investigation. Thus, these studies can corroborate with current and fu

11. Capture and 3D modeling of hands with motion tracking / Captura e modelagem 3D de mãos com rastreamento de movimentos
Currently, general-purpose computers come equipped with webcams cameras of good resolution and high-speed, which enables a visually user interaction, through gestures, with software applications. This allows a greater sense of reality in interactive processes of virtual and augmented reality. The goal of this research is to capture and compose 3D model of ha

12. Influência das propriedades físico-mecânicas e hídricas do solo na susceptibilidade a escorregamentos em vertente declivosa na Serra do Mar em Ubatuba, São Paulo / Influence of physical and mechanical properties of soil an hydro in susceptibility to landslides on steep slopes in the Serra do Mar, Ubatuba
The mass movements are natural phenomena of evolution of the slopes, but they cause great damage when being considered as a risk in one area if they have a vulnerability in the slope associated with human occupation or industry that brings risk population. The study area is located on the northern coast of São Paulo, Brazil. In the region of Serra do Mar, a
