Fratura supracondiliana do fêmur durante salto após reconstru??o artroscópica do ligamento cruzado anterior
Fukuda, Thiago Yukio;Yazbek, Paula Meletti;Bryk, Flavio Fernandes;
Revista Brasileira de Medicina do Esporte , 2009, DOI: 10.1590/S1517-86922009000200011
Abstract: background: distal femoral fracture is one of the possible complications on the post operative period of the acl reconstruction; however, with rare incidence. case report: this study reports a male 34 year-old athlete, five months after acl reconstruction surgery. the case developed normally in accordance with the established protocol. the patient presented good control and sensory-motor stability when he suffered a supracondylar femur fracture. this fracture occurred during a jump in the physical therapy treatment. the ligament reconstruction was done with the tendon graft of the knee flexors muscles, and the fracture caused later, was reduced and stabilized with plate and screw. ten months after open reduction and internal fixation of the fracture, the patient showed regular function in the lysholm scale, normal range of movement and muscular force grade v for knee flexors and extensors. discussion: few case reports similar to the present one were found in the literature. the majority presented femur fracture after acl reconstruction with patellar tendon. the present case shows significance by the association between supracondylar femur fracture with ligament reconstruction with flexors tendon, since only one case followed this direction. two of the possible causes of this fracture are bone fragility for disuse and femoral tunnel bone bigger than the normal, despite not being a consensus. a hypothesis suggested by the authors of this paper is that the bone tunnel of graft fixation could have been a stress booster to the site of the fracture.
Ankle Phenomenon in the Cosmic Ray Energy Spectrum  [PDF]
Yukio Tomozawa
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.43054
Abstract:

The author has suggested that the knee phenomenon in the cosmic ray energy spectrum at 3 PeV can be explained as a split between a radiation-dominated expansion and a matter-dominated expansion of an expanding heat bath. The model proposed in 1985, in fact, predicted that high energy cosmic rays are emitted from AGN, massive black holes, in agreement with recent data from the Pierre Auger Observatory. Similarly, the ankle phenomenon at 3 EeV is shown to be explained by a split between inflational expansion and ordinary material expansion of the expanding heat bath, not unlike that in the expansion of the universe. All the spectral indicies in the respective regions of the energy spectra agree with the theoretical calculation from the respective expansion rates. It is shown that the ankle energy is approximately equal to the threshold energy of cosmic ray production of an electron positron pair on the cmb photon.

Experimental Test of General Relativity and the Physical Metric  [PDF]
Yukio Tomozawa
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.63036
Abstract: The author will show that neither the Schwarzschild metric nor the metric introduced in 1916 by Schwarzschild describes the data produced by the time delay experiment by Shapiro et al. The author will describe the physical metric that will explain the time delay experiment data correctly as a solution to Einstein Equation of General Relativity. Other tests of General Relativity, the bending of light, the advancement of perihelia, gravitational red shift and gravitational lensing are satisfied by both the Schwarzschild metric and author’s physical metric.
The Physical Metric and Compact Objects  [PDF]
Yukio Tomozawa
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.67101
Abstract: In the previous work, the author introduces the physical metric for spherically symmetric and static metric which satisfies all the experimental tests of general relativity. This metric changes the nature of gravity for compact objects, such as black holes and neutron stars. It introduces the extended horizon which is 2.60 times of the Schwarzschild radius and plays a determinant role in the size of compact objects. This provides the prediction that the gravitational red shift z on the surface of compact objects is universal value of \"\". None of the observed neutron stars rotate fast enough to change this prediction significantly. The gravity inside the extended horizon is repulsive. The effect of this repulsive force causes supernova explosion, high energy cosmic ray generation from AGN and explains the acceleration of the universe expansion.
Temperature Structure of Compact Objects  [PDF]
Yukio Tomozawa
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.610146
Abstract: Based on the physical metric proposed by the author, temperature distribution for compact objects, neutron stars and black holes, has been explained. Outside the extended horizon, the temperature is positive and approaches infinity at the extended horizon boundary. Inside the extended horizon, the temperature is negative which implies higher temperature than outside the horizon. This outcome is the result of the repulsive nature of gravity inside the extended horizon in the author’s physical metric. Overall, the physical metric explains temperature structure of compact objects more completely than the Schwarzschild metric, and is supported by the emerging evidence of X-ray data collected from neutron stars and black holes (AGN).

Acta Ortopédica Brasileira , 2011, DOI: 10.1590/S1413-78522011000600002
Abstract: objective: to evaluate the strength of internal rotation, external rotation and elevation of the shoulders of symptomatic compared with asymptomatic patients, associating muscle strength with joint function. methods: forty-eight individuals diagnosed with unilateral sis were evaluated in relation to isomeric muscle strength of symptomatic and asymptomatic shoulders (using a hand-held isometric dynamometer), in addition to evaluating function using the constant-murley scale. the subjects were divided into 2 groups: group 1 = 35 to 49 years, group 2 = 50 to 65 years. results: a reduction in strength of internal rotation, external rotation and elevation of the symptomatic shoulder were found, compared with the asymptomatic side (p <0.0001), but there was no reduction in the strength of medial rotation in the subjects of group 1. it was observed that muscle strength is directly proportional to shoulder function, with individuals with little strength of the rotator cuff having less function. conclusion: sis causes decreased muscle strength of internal rotation, external rotation and elevation compared with the asymptomatic side. it also causes decreased shoulder function. the reduced function is proportional to the decrease in muscle strength of the rotator cuff. level of evidence: level iii, analytical study
Performance Prospects of Fully-Depleted SOI MOSFET-Based Diodes Applied to Schenkel Circuit for RF-ID Chips  [PDF]
Yasuhisa Omura, Yukio Iida
Circuits and Systems (CS) , 2013, DOI: 10.4236/cs.2013.42024
Abstract:

The feasibility of using the SOI-MOSFET as a quasi-diode to replace the Schottky-barrier diode in the Schenkel circuit is examined by device simulations primarily and experiments partly. Practical expressions of boost-up efficiency for d. c. condition and a. c. condition are proposed and are examined by simulations. It is shown that the SOI-MOSFET-based quasi-diode is a promising device for the Schenkel circuit because high boost-up efficiency can be gained easily. An a. c. analysis indicates that the fully-depleted condition should hold to suppress the floating-body effect for GHz-level RF applications of a quasi-diode.

Physical and Electrolytic Properties of Monofluorinated Ethyl Acetates and Their Application to Lithium Secondary Batteries  [PDF]
Noritoshi Nambu, Yukio Sasaki
Open Journal of Metal (OJMetal) , 2015, DOI: 10.4236/ojmetal.2015.51001
Abstract: Ethyl acetate (EA) shows low viscosity for its relative permittivity. Monofluorinated organic solvents exert the polar effect on the various properties. We have investigated the effect of position isomerism on the physical and electrochemical properties of two monofluorinated carboxylates: 2-fluoroethyl acetate (2FEA) and ethyl fluoroacetate (EFA). Relative permittivity of 2FEA was lower than that of EFA, whereas viscosity of 2FEA was higher. Electrolytic conductivity of a LiPF6 solution in 2FEA was lower than that in EFA, but higher than that in EA at high temperatures. The use of 2FEA as a co-solvent improved cycling efficiency and suppressed fading of discharge capacity of a Li|LiCoO2 coin cell at high cycle numbers.

Abstract: background: knee osteoarthritis (koa) is one of the major reasons for seeking medical and physical therapy services, because it usually causes difficulties in performing daily life activities. there are several types of treatment, with varied results. the use of knee sleeve as an adjuvant resource has been controversial in the literature. objective: to assess the immediate efficacy of elastic knee sleeve on pain and functional capacity of individuals with koa. methods: seventy-four patients (132 knees) with symptomatic koa were assessed by use of the stair climb power test (scpt), timed up and go (tug) and 8-meter walk (8mw) tests, in addition to the vas for pain. the tests were performed with and without knee sleeves, with a cover on the knees to hide knee sleeve. the order and the presence of the knee sleeve were randomized, and the investigator was blind. results: a statistically significant difference was found between the two compared circumstances (with and without knee sleeve) when using the vas (p < 0.001), which showed a reduction in pain with the knee sleeve use. analyses of the three functional tests under both circumstances were performed, resulting in statistically significant differences in 8mw and tug tests (p < 0.05), but not in scpt (p > 0.1339). conclusion: the elastic knee sleeve proved to be effective to immediately improve the functional capacity and pain of individuals with koa, because it enhanced performance during the tests proposed. thus, the knee sleeve is an adjuvant resource for treating koa, because it is practical, useful, and of easy clinical use, and can aid in the practice of therapeutic exercises.
