Sounds can induce autonomic responses in listeners. However, the modulatory effect of specific frequency components of music is not fully understood. Here, we examined the role of the frequency component of music on autonomic responses. Specifically, we presented music that had been amplified in the high- or low-frequency domains. Twelve healthy women listened to white noise, a stress-inducing ...

Word reduction by weak syllable omission is a fairly common phenomenon in several populations, including normally developing children, children with Specific Language Impairment, and adults with aphasia. A recent study (Carter & Clopper, submitted) has shown that normal adults reduce words using strategies similar to those used by the above-mentioned populations and that these strategies vary t...

In this article, the free vibration analysis of magneto-electro-elastic (MEE) Timoshenko micro beam model based on surface stress effect and modified strain gradient theory (MSGT) under moving nano-particle is presented. The governing equations of motion using Hamilton’s principle are derived and these equations are solved using differential quadrature method (DQM). The effects of dimensionless...

Non-chemical control of plant growth is an important goal for the production of ornamental pot plants. In the present study the effects of simulated vibration on plant height and some physical and mechanical properties of Coleus stem were investigated. The study was conducted as a factorial experiment based on a completely randomized design with three replications. Vibration stresses were perfo...

Background and aimsScientific and industrial development has led to increased production,which has been associated with different complications, including occupational stress, and increased incidence of work-related musculoskeletal disorders. Musculoskeletal disorders arefrequent causes of absenteeism in developed countries. We designed this study to assess musculoskeletal disorders and occupat...

background: stress may cause damages to dna or/and change the ability of the cells to overcome these damages. it may also cause irregularities in the cell cycle and induce abnormal cell divisions through glucocorticoid-dependent functions. the abnormal cell divisions, in turn, lead to chromosomal mal-segregation and aneuploidy. in this study, the effects of the stress hormone, hydrocortisone (h...

Background: Infertility is a painful emotional experience associated with stress. Objectives: The present study aimed at determining infertility-related stress and its associated factors in infertile clients referred to the infertility clinic of Al-Zahra hospital in Rasht, Iran, in 2019. Methods: The present cross-sectional study was performed on 200 clients undergoing infertility treatment, ...

Dynamic behaviour of nonlinear free vibration of circular plate resting on two-parameters foundation is studied. The governing ordinary differential equation is solved analytically using hybrid Laplace Adomian decomposition method. The analytical solutions obtained are verified with existing results in literature. The analytical solutions are used to determine the influence of elastic fou...

Life satisfaction of migrants to Australia from 17 countries, assessed at 4-5 months, 16-17 months and 3½ years after arrival, was analyzed with a longitudinal, multilevel analysis. The results indicated that migrants were more satisfied, if the national average life satisfaction was higher in their country of origin, after adjustment for individual-level income, age, and sex and a linear tempo...

In this paper, the vibrations of thin plate in modified couple stress thermoelastic medium by using Kirchhoff- Love plate theory has been investigated. The governing equations of motion and heat conduction equation for Lord Shulman (L-S) [1] theory are written with the help of Kirchhoff- Love plate theory. The thermoelastic damping of micro-beam resonators is analyzed by using the normal mode a...
