conclusions the study findings highlight the importance of the mental aspect of fatigue in this working group. these results have possible implications for workers’ health and well-being and for the design of shift work systems, for industrial workers. background shift work is a well-recognized occupational health hazard in both industrialized and industrially developing countries. prolonged wo...
background: occupational asthma (oa) is the most common occupational lung disease in developed countries. one of the causative agents is metal fume that may be encountered in steel industries. screening for the oa is mainly performed by questionnaire but in our country spirometry is used more commonly. objective: to compare the diagnostic value of the venables standardized respiratory questionn...
We consider applications of clustering techniques, Mean Shift and Self-Organizing Maps, to surface reconstruction (meshing) from scattered point data and review a novel kernel-based clustering method.
objective: identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. methods: najdi cattle is the most prominent breeds in khuzestan province. to do this plan in shoushtar najdi cattle station, blood samples were taken from 15 najdi cattles. dna was extracted from wh...
background although magnetic resonance spectroscopy (mrs) has been shown as an effective diagnostic tool in distinguishing inflammation from neoplasm in cystic brain lesions, the optimum approach in selecting the portions of lesions in mrs and the possible effects of different times of echoes (tes) remains unknown. objectives to determine the most effective te in diagnosing neoplastic lesions b...
Aim: The aim of this research was comparison of IHD’S risk factors between shift workers in automobile industries in Iran. Materials & Methods : Knowledge of IHD risk factors and demographic data have gathered by using hygienistic files of workers, data had been analyzed with SPSS 11.5 and significance’s level (p value) was less than 0.05. Results: The mean of HDL cholesterol in one-shift...
A stable discrete-time control system may become unstable when the discrete-time control law is implemented with a xed-point digital control processor (DCP) due to the nite word length (FWL) eeects which depend on the control law structures and the discrete-time representations (e.g., delta operator or forward-shift representations) used to represent the control laws. To improve closed-loop sta...
The aim of this study was to investigate modulation of voltage-dependent steady-state activation and availability from inactivation of the cardiac Na+ channel by the cytoskeleton. As an experimental approach, we used long-lasting monitoring [63 ± 5 (SE) min] of the half-point potentials of the steady-state availability curve ( V 1/2A ) and normalized conductance curve ( V 1/2G) in 116 rat ventr...
The universal enveloping algebra of any simple Lie algebra g contains a family of commutative subalgebras, called the quantum shift of argument subalgebras [R, FFT]. We prove that generically their action on finitedimensional modules is diagonalizable and their joint spectra are in bijection with the set of monodromy-free G -opers on P with regular singularity at one point and irregular singula...
