The effect of coping techniques training on coping strategies of infertile women in Kermanshah

Background: Psychological problems of infertility can be a contributory factor in intensity of infertility. The aim of this study was to estimate the effectiveness of coping techniques training on coping strategies of infertile women in Kermanshah. Methods: Among the women who visiting infertile clinic, 40 volunteer women had been chosen and randomly divided equally into two experimental and control groups. In pre test phase, subjects in both groups simultaneously answer to Folkman- Lazarus coping strategies questionnaire. In next phase, only experimental group treated to 8 (120 minutes) sessions. After terminating treatment sessions both groups simultaneously in post test and follow up phases by the mentioned questionnaire had been tested again. In order to analysis the data SPSS software version 16 were used and analysis of variance with repeated measurement was employed. Results: There were meaningful differences (P<0.05) between and among scores of self–controlling coping, seeking social support, accepting responsibility, plan full problem solving, positive reappraisal, escape-avoidance, in infertile women in pre test, post test and follow up phases, while there was not statistically significant difference between encountering and avoidance strategies. Conclusion: Coping technique training helped the increasing of using coping strategies for self–controlling, seeking social support, accepting responsibility, plan full problem solving, positive reappraisal and the decreasing of using escape–avoidance coping in infertile women in Kermanshah

The Empirical Study on the OTC Brand Assets Value Evaluation

SUN Wei School of Automobile, Chang’an University, Xi’an, P.R.China, 710064 sunweijoy@163.com Abstract: Because of its intangibility,the brand assets is more difficult to be measured than the tangible assets.

Finally this paper empirical studies the OTC brand assets value evaluation model.

Stress intensity factors for cracks initiated from a center-holed plate with unsymmetrical lengths under tension

Abstract The values of stress intensity factors of unsymmetrical cracks initiated from hole edges under tension were calculated in a center-holed plate, that is a plate having a hole in the center of a front face. The correction factor for stress intensity in the case of the holed plate with cracks was compared with that of a center-cracked plate whose crack length was equal to the total of the hole diameter and the lengths of the cracks in the case of the holed plate. In the present study, to understand the variation of the stress intensity factor, counterplots of the stress intensity factor K I and the correction factor F I are employed. Also, the variation of ratio R F of correction factors between the holed plate with crack and the center-cracked plate were investigated. Where non-dimensional hole diameter a / W is smaller than 0.2, the ratio R F is less than 1.1 after crack growth length c / W reaches 0.1. Where, 2 a , 2 c and 2 W are hole diameter, the growth length of the crack from hole edge, and plate width, respectively. Therefore, the stress intensity factor for cracks initiated from a holed plate can be approximated within 10% error to that of a center-cracked plate where a / W is smaller than 0.2, though the unsymmetrical cracks are initiated from the edges. Where a / W is larger than 0.3, R F becomes larger than 1.1 in the wide range of c / W .

Synthesis and Characterization of Tb-doped AlBNO Films for Electroluminescence Devices

AbstractTb-doped AlBNO (AlBNO:Tb) films with various composition ratios are investigated for luminescence layers of inorganic electroluminescence(EL) devices. Luminescence layers with a wide bandgap and a low dielectric constant are required to realize high performance of EL devices. The ultraviolet-visible radiation absorption measurement and capacitance-voltage (C-V) measurement show that the AlBNO:Tb films have wider bandgap and lower dielectric constant than ZnS which is put to practical use as the host material of the luminescence layer. Photoluminescence (PL) measurement indicates that PL intensity increases with increasing B composition ratio in the range of 5 % - 10 %. Moreover, the suppression factor of the PL intensity can be understood through the annealing experiment. The PL intensity of the film with 800 °C annealing is about 10 times larger than that of the film without annealing. X-ray photoelectron spectroscopy (XPS) measurement suggests that Tb4+ ions decrease compared with Tb3+ ions after annealing treatment. O atoms in the AlBNO:Tb film are dissociated from Tb and bonded to B atoms by annealing treatment. This suggests that decrease of Tb4+ ions is related to increase of the PL intensity.

Effects of Digital Doping of Mn on Giant Magneto-Optical Properties of Zn1−xMnxSe Quantum Wells

We have studied effects of the digital-doping profile of MnSe layers on the giant magneto-optical properties in Zn1−xMnxSe-based quantum wells. The giant Zeeman shift energy increases monotonically with increasing spatial overlap of the exciton wavefunction with the 0.5 monatomic-thick effective Mn layers at the interfaces between the digitally doped MnSe layers and nonmagnetic ZnSe layers. Also, a field-induced enhancement factor of the excitonic photoluminescence intensity, because of the suppression of the exciton energy transfer into the d-d transition of Mn-ions, increases linearly with increasing such overlap of the exciton wavefunction with the effective Mn layer. In addition, the formation energy as large as 18.6 meV and the formation time of the magnetic polaron are determined, which are also affected by the digital-doping profile.

Morphofunctional Analysis of Effect of Short-Term Sleep Deprivation on the Wakefulness–Sleep Cycle in Young and Adult Rats

The work presents comparative data on changes of neurophysiological, time characteristics of the wakefulness–sleep cycle (WSC) and morphofunctional state of neurosecretory cells in supraoptic nucleus of the hypothalamus, which develop under influence of a 6-h long sleep deprivation in adult and one-month old rats. It is shown that the rebound of sleep develops in adult animals with a delay, after the 3rd hour and is characterized by a moderate increase of portions of slow-wave (SSP) and fast-wave (FSP) sleep phases in WSC and by a decrease of the wakefulness portion. Morphological analysis of the hypothalamus nonapeptidergic system has revealed a rise of content of neurosecretory material in fibers of supraoptic nucleus cells an in area of supraoptic-pituitary tract, as well as marked hyperemia that indicates activation of processes of secretion of neurohormones into the general blood flow; these reactions are similar to reactions of this system to stress. In rat pups the sleep rebound develops in 0.5 h after the end of the deprivation procedure and is characterized by more pronounced, statistically significant changes in WSC. Individual WSC become very short and almost all of them are completed with episodes of FSP. A statistically significant rise of power of the δ-wave band in electrogram spectra of hippocampus and somatosensory cortex in SSP, whereas peak of the activity in FSP is shifted to α-waves. Ratios of SSP and FSP to wakefulness in individual WSC in mature animals increase after the deprivation 1.53 and 1.85 times, while they are elevated in one-month old animals 5.25 and 6.75 times, respectively. The obtained morphofunctional data allow believing that deprivation is the stress factor of low intensity for adult animals, whereas it may be considered as the stress action of intermediate and even high intensity for rat pups, which changes essentially the interrelations in WSC. Participation of central mechanisms of regulation of sleep and vigilance, which provide processes of compensation of damaging action of deprivation on WSC in the maturing animals, is discussed.

EFFECTS OF UNSTEADINESS ON INNER-LAYER CHARACTERISTICS IN SMOOTH OPEN-CHANNEL FLOWS

The inner layer and outer layer of unsteady smooth open channel flows were measured by making use of a twocomponent laser Doppler anemometer (LDA) under the condition that the unsteadiness parameter is very high. In such a situation the von Karman constant decreases in the rising stage and decreases in the falling stage. The friction velocity evaluated from the log law does not coincide with that evaluated from the linear formula in the viscous sublayer with an increase of the unsteadiness. In contrast, the characteristics of normalized turbulence are not affected by the unsteadiness so much; the van Driest's damping factor of the turbulence intensity of the streamwize is almost constant against the normalized time. The third-order moments of the turbulence agree well with those of the steady uniform flow.

On the determination of depth from overlapping side‐scan sonar images

Abstract A method for obtaining depth determinations from overlapping side‐scan sonar is presented. The technique is analogous to the photogrammetic method of deriving topographic measurements from aerial photographic stereo pairs. In the aerial case, image overlap is in the along‐track direction and topographic measurements are based on image parallaxsis. The overlap of the sonar images is in the across‐track sense, and the look directions of the two images are opposed. In terrains where slope is the controlling factor of image intensity, the opposite look directions may yield radically distinct images, thus invalidating traditional photogrammetric measurement techniques. We present a new approach based on matching image edge features rather than image intensities. The algorithm is tested on synthetic imagery generated from a bathymetric model and the results are excellent. Application to actual imagery yielded viable depth determinations consistent with trend and ancillary data.

The X-ray diffraction intensity of cyclically loaded Al

The displacement field around a dislocation loop had been calculated to give the diminishing factor of X-ray diffraction intensity from a fatigued Al sample. Experimentally had been measured this factor on the samples fatigued at room temperature and at low temperature. From these the size and density of dislocation loops can be deduced. Results show that in the sample fatigued at room temperature there is no significant change in dislocation structure while at low temperature in fatigued sample occurs a large amount of dislocation loops whose density is 1014−1017cm−3 while their radii are between 100 and 1000 A.

Rotatory-Diffusion Broadening of Rayleigh Lines Scattered from Optically Anisotropic Macromolecules in Solution

A technique for the spectroscopic detection of pure rotatory Brownian movement of anisotropic macromolecules in solution are developed in combination with a high-resolution optical heterodyne spectrometer. The line broadening originating in the translational diffusion of the solute macromolecule, which is a dominant factor in intensity in the Rayleigh component, is suppressed by taking the forward scattering. Then, only the depolarized light whose amplitude is fully modulated by the rotation of solute molecules is filtered off by the polarizer and received by a photomultiplier tube. The time-dependent component of the output from the phototube is analyzed by a wave analyzer to give a spectrum of the scattered light. From the spectral linewidth thus obtained, the rotatory diffusion coefficient of Tobacco Mosaic Virus in aqueous solution has been obtained and found to be 350 ± 20 sec−1. On the other hand, the optically isotropic polystyrene latex sphere has shown no broadening in this system. From these results and from the evidence of sharpening of the linewidth with increasing solvent viscosity, it is concluded that the observed broadening originates in the amplitude modulation of the scattered light by the rotatory diffusion of TMV. This “depolarized light mixing” technique is quite general and able to cover a frequency range from 101 to 107 Hz. And it is believed to be useful especially in the studies of rotatory diffusion and transconformation of anisotropic macromolecules, and in studies of chemical kinetics accompanying an anisotropic change of polarizabilities.
