background: fatigue is one of the important factors in nursing performance because it affects the quality of care provided to the patients. in this regard, some complementary interventions such as benson relaxation techniques may relieve fatigue. this study aimed to evaluate the effect of benson relaxation on fatigue of nurses working in intensive care units. methods: this is an experimental st...

conclusions the benson relaxation could reduce pain intensity in women after cesarean section. results the mean of pain score before intervention at cg was 4.43 cm. it was decreased to 4.40 cm (1 min), 4.27 cm (12 h), 4.10 cm (24 h), 4.00 cm (36 h), 3.93 cm (48 h), 3.83 cm (60 h), 3.67 cm (72 h) and 3.51 cm (84 h). meanwhile, the ig was 4.97 cm. it was decreased to 4.90 cm (1 min), 4.23 cm (12 ...

background and purpose: anxiety is a common problem associated with invasive medical procedures, especially in patients undergoing coronary angiography. as an intensifier at cardiovascular reactions, anxiety poses significant risk to the health of patients undergoing angiography. researchers believe that use of benson’s relaxation technique could reduce anxiety in different patients. this study...

objective behavioral interventions such as relaxation training and biofeedback are some of the most effective interventions for management of migraine headaches. in this study we evaluated the utility of biofeedback-assisted progressive muscle relaxation training (prt) in the treatment of migraine. materials and methods in this prospective study, twenty patients (12-18 years old) with a confirm...

we will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. the confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional schrodinger equation. excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...

The theory of materials with internal state variables of Coleman and Gurtin CG] provides a natural framework to investigate the structure of relaxation approximations of conservation laws from the viewpoint of continuum thermomechanics. After reviewing the requirements imposed on constitutive theories by the principle of consistency with the Clausius-Duhem inequality, we pursue two speciic theo...

We present time-dependent dielectric loss data for various glass formers below the glass temperature. The observed aging dynamics is described using a modified Kohlrausch-Williams-Watts law taking into account the variation of the relaxation time during aging. It leads to values for the aging relaxation time and stretching exponent, fully consistent with the results from equilibrium measurement...

To realize the high-efficiency and high-performance manufacture of complex high-web panels, this paper introduced electric pulse current (EPC) into the stress relaxation aging forming process of 2219 aluminum alloy and systematically studied the effects of EPC, stress, and aging time upon the microstructure and properties of 2219 aluminum alloy. It is discovered that: (a) EPC greatly enhanced t...

The dielectric spectra of most simple liquids are characterized by two relaxation processes: (i) the alpha-process, an intense, broad non-Debye relaxation with a non-Arrhenius temperature dependence and (ii) a beta process, evident mainly below the glass transition and having nearly Arrhenius temperature behavior. However, the dielectric spectra of monoalcohols show three processes: two that re...
