1. A 120-second stretch improves postural control and plantar pressure: quasi-experimental study
ABSTRACT BACKGROUND: There are no studies on long-term bilateral calf stretching in relation to balance and plantar pressure. OBJECTIVES: To demonstrate that there is better control of posture and pressures after continuous stretching of the posterior calf muscles. DESIGN AND SETTING: Pre and post-intervention study conducted in a private clinic. METHODS

2. A prospective case series on surgical treatment of circumferential and semi-circumferential defects due to peri-implantitis
Abstract Different surgical treatment strategies for peri-implantitis with the use of graft material and membranes have been suggested without any longitudinal remarkable success rate. The present preliminary study was aimed to analyze a new clinical approach based on the disinfection of the implant connection, the disinfection of the implant surface and GBR

3. Dissipation and mass redistribution as a mechanism of propulsion in closed systems
Abstract In this work, the mechanism behind motion in closed systems is investigated by studying two simple mechanical systems. Firstly, a simple “ballistic” car system introduces the subject of propulsion as a function of a parameter that modulates the amount of ejected mass, thus allowing a transition between a closed to an open system. The second exam

5. American Space Nuclear Electric Systems
ABSTRACT: Since the 1960's the United States of America has launched several space missions using nuclear technology as a mean for propulsion and power supply. The majority of the American nuclear powered spacecrafts were based in radioisotope generators, with the exception of the SNAP-10A (1965), which was the only American reactor ever launched. However, s

6. Effect of Loose Bonding and Corrugated Boundary Surface on Propagation of Rayleigh-Type Wave
Abstract The problems concerns to the propagation of surface wave propagation through various anisotropic mediums with initial stress and irregular boundaries are of great interest to seismologists, due to their applications towards the stability of the medium. The present paper deals with the propagation of Rayleigh-type wave in a corrugated fibre-reinforc

7. Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study
Abstract Objective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instrumented with nickel-titanium rotary file and the final f

8. Full-thickness skin mesh graft vaginoplasty: a skin sparing technique
ABSTRACT Introduction: The ideal vaginoplasty method should promote good cosmetic and functional results with low morbidity. We describe a new technique for congenital vaginal agenesis using a full-thickness perforated skin graft. Materials and Methods: We report an 18 year old patient with vaginal agenesis (Morris syndrome) that undergone a modified versi

9. Infection process of Phakopsora gossypii in cotton leaves
ABSTRACT Tropical rust caused by the biotrophic fungus Phakopsora gossypii is an emerging disease in cotton that has caused significant yield losses of crop/cotton cultivated in Brazil. Considering the current importance of tropical rust and the need to obtain additional basic information about its causal agent to better control this disease, the present stu

10. Impact Response of Aluminium Alloy Foams Under Complex Stress States
Abstract A series of dynamic tests were conducted on a closed-cell aluminum alloy foams in order to determine experimental failure surface under impact loading conditions. Quasi-static tests have also been performed to investigate failure mechanism under different stress paths. Three typical types of deformation modes can be observed, which corresponds to th

11. Characterization of copper microelectrodes, following a homemade lithography, technique, and gold electroless deposition
We report the fabrication and characterization of copper microelectrodes obtained by a homemade lithography technique and after gold electroless deposition. For the fabrication, planes consisting of arrays of electrodes (black in color) with bow tie shape were designed and printed on a transparent paper (Canson ltd.). Using an embroidery frame with a silk fa

12. Analysis of static and dynamic balance in healthy elderly practitioners of Tai Chi Chuan versus ballroom dancing
OBJECTIVE: To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. METHODS: We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Maste
