Pengaruh Penatalaksanaan Terapi Latihan Terhadap Kepuasan Pasien Fraktur Di Irina a Blu Rsup Prof. Dr. R.d. Kandou Manado

Rehabilitation treatment in patients with fractures include physical therapy, which consists of various types of exercises: isometric muscle exercises and active and passive ROM exercises. Exercise therapy is one treatment efforts in the implementation of physiotherapy exercises using body movements, either actively or passively (Kisner, 1996). The goal of rehabilitation exercise therapy is to address the function and movement disorders, prevent complications, reduce pain and edema as well as functional activity due to train operations. This study uses a pre-experiment design with the research method that is static group comparison, sample of 49 people consisting of 24 people sampled in the experimental group and 25 samples in the control group. data processing is done through analysis of test Chi Square (X ²) of two samples. The results of patient satisfaction rate of fracture after receiving the treatment (experimental group) were 22 respondents were satisfied and 2 respondents were not satisfied to exercise therapy given. While the group did not receive treatment that is there are 24 people were not satisfied and only one person who was satisfied, chi square analysis of two samples based on the results of each group then found count rates χ2 χ2 is greater than the price of a good table for the standard error of 5% or 1%. There are differences in satisfaction levels between the two groups of fracture patients to exercise therapy. There is the influence of exercise therapy for treatment of fractures of patient satisfaction in the department of Prof. Irina A BLU. Dr. R.D. Kandou Manado

Radiative damping in wave guide based FMR measured via analysis of perpendicular standing spin waves in sputtered Permalloy films

The damping $\alpha$ of the spinwave resonances in 75 nm, 120 nm, and 200nm -thick Permalloy films is measured via vector-network-analyzer ferromagnetic-resonance (VNA-FMR) in the out-of-plane geometry. Inductive coupling between the sample and the waveguide leads to an additional radiative damping term. The radiative contribution to the over-all damping is determined by measuring perpendicular standing spin waves (PSSWs) in the Permalloy films, and the results are compared to a simple analytical model. The damping of the PSSWs can be fully explained by three contributions to the damping: The intrinsic damping, the eddy-current damping, and the radiative damping. No other contributions were observed. Furthermore, a method to determine the radiative damping in FMR measurements with a single resonance is suggested

Damping of gravitational waves by matter

We develop a unified description, via the Boltzmann equation, of damping of gravitational waves by matter, incorporating collisions. We identify two physically distinct damping mechanisms -- collisional and Landau damping. We first consider damping in flat spacetime, and then generalize the results to allow for cosmological expansion. In the first regime, maximal collisional damping of a gravitational wave, independent of the details of the collisions in the matter is, as we show, significant only when its wavelength is comparable to the size of the horizon. Thus damping by intergalactic or interstellar matter for all but primordial gravitational radiation can be neglected. Although collisions in matter lead to a shear viscosity, they also act to erase anisotropic stresses, thus suppressing the damping of gravitational waves. Damping of primordial gravitational waves remains possible. We generalize Weinberg's calculation of gravitational wave damping, now including collisions and particles of finite mass, and interpret the collisionless limit in terms of Landau damping. While Landau damping of gravitational waves cannot occur in flat spacetime, the expansion of the universe allows such damping by spreading the frequency of a gravitational wave of given wavevector.Comment: 9 pages (10 pages in journal), published versio

Damping of bulk excitations over an elongated BEC - the role of radial modes

We report the measurement of Beliaev damping of bulk excitations in cigar shaped Bose Einstein condensates of atomic vapor. By using post selection, excitation line shapes of the total population are compared with those of the undamped excitations. We find that the damping depends on the initial excitation energy of the decaying quasi particle, as well as on the excitation momentum. We model the condensate as an infinite cylinder and calculate the damping rates of the different radial modes. The derived damping rates are in good agreement with the experimentally measured ones. The damping rates strongly depend on the destructive interference between pathways for damping, due to the quantum many-body nature of both excitation and damping products.Comment: 5 pages, 4 figure

Dynamical shift condition for unequal mass black hole binaries

Certain numerical frameworks used for the evolution of binary black holes make use of a gamma driver, which includes a damping factor. Such simulations typically use a constant value for damping. However, it has been found that very specific values of the damping factor are needed for the calculation of unequal mass binaries. We examine carefully the role this damping plays, and provide two explicit, non-constant forms for the damping to be used with mass-ratios further from one. Our analysis of the resultant waveforms compares well against the constant damping case.Comment: 10 pages, 14 figure

Practical aspects in measuring vibration damping of materials

Already many years material damping data is available from literature, but often there is no consistency in the presented damping values. One reason is the wide availability of testing apparatus for measuring damping, each having its own pros and contras. Next to that, damping data can be analysed in many ways such that obtaining a uniform damping value for a specific material is far from obvious. The work in this paper focuses on finding an accurate and repeatable test method for measuring low damping values. It is found that the suspension has a large influence in test setups for low damping measurements and that material damping varies with sample geometry and stress level

Damping of MHD turbulence in partially ionized plasma: implications for cosmic ray propagation

We study the damping from neutral-ion collisions of both incompressible and compressible magnetohydrodynamic (MHD) turbulence in partially ionized medium. We start from the linear analysis of MHD waves applying both single-fluid and two-fluid treatments. The damping rates derived from the linear analysis are then used in determining the damping scales of MHD turbulence. The physical connection between the damping scale of MHD turbulence and cutoff boundary of linear MHD waves is investigated. Our analytical results are shown to be applicable in a variety of partially ionized interstellar medium (ISM) phases and solar chromosphere. As a significant astrophysical utility, we introduce damping effects to propagation of cosmic rays in partially ionized ISM. The important role of turbulence damping in both transit-time damping and gyroresonance is identified.Comment: 29 pages, 16 figure
