aim and background: psychological factors have a pivotal role in the chronicity of diseases. chronic pain may lead to depression and disabilities in patients, which may change their quality of life and life style. the aim of this study was to evaluate the relationship between coping strategies, depression, physical disability, and pain intensity in people with chronic back pain. method and mate...

The honeybee has been established as an important model organism in studies on visual learning. So far the emphasis has been on appetitive conditioning, simulating floral discrimination, and homing behavior, where bees perform exceptionally well in visual discrimination tasks. However, bees in the wild also face dangers, and recent findings suggest that what is learned about visual percepts is ...

background: schistosomiasis and soil transmitted infection is a major health problem of children from rural areas of developing countries including yemen. in an attempt to reduce this burden, the ministry of public health and population in yemen established in 2002 a programme for schisto-somal, soil transmitted infection control that aimed to reduce morbidity and prevalence rates of schistosom...

In this paper, we demonstrate the temperature of lightning channel utilizing the theory of lightning spectra and the model of local thermodynamic equilibrium (LTE). The impulse current generator platform (ICGS) was used to simulate the lightning discharge channel, and the spectral energy of infrared spectroscopy (930 nm) and the visible spectroscopy (648.2 nm) of the simulated lightning has bee...

football participation requires considerable utilization of both aerobic and anaerobic energy systems to match the high energetic demands of the sport. the consequent stresses imposed on the physiological and metabolic systems carries players to the threshold of exhaustion during match-play, from which they are required to recover in preparation for the subsequent game. a high number of players...

There are various ways to impose a potential variation in time, and subsequently a series of voltammetric methods. Cyclic voltammetry relies on linearly scanning the potential in time, observing a triangular waveform variation [1-3]. Differential pulse voltammetry is based on two samplings of the current intensity for each potential pulse: one measurement before applying the pulse, and the seco...

The time-harmonic eddy current problem with either voltage or current intensity excitation is considered. We propose and analyze a new finite element approximation of the problem, based on a weak formulation where the main unknowns are the electric field in the conductor, a scalar magnetic potential in the insulator and, for the voltage excitation problem, the current intensity. The finite elem...

The long-term goal of this project is to improve the prediction of tropical cyclone (TC) genesis, structure and intensity changes through improved representation of 3-dimensional TC structure at the initial time. The accurate prediction of TC genesis, structure and intensity changes is critical to Navy missions and civilian activities in coastal areas. Significant gains have been made in the TC...
