This study investigated the influence of the torque produced by plantar flexor muscles on cortical and spinal excitability during lengthening and shortening voluntary contractions. To that purpose, modulations of motor-evoked potential (MEP) and Hoffmann (H) reflex were compared in the soleus (SOL) and medial gastrocnemius (MG) during anisometric submaximal and maximal voluntary contraction (MV...

in this study, the isothermal reduction of iron oxide pellets, made of iranian chadormalo, gole-gohar, and sangan iron ores, was investigated in the temperature range of 900-1100°c. tabas, pabdana, babnizoo, karmozd, and shahrood domestic coals were used as reductants. parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...

The intent of begun work is to synthesis and study the structural, electric, magnetic frequency dependent dielectric properties Ni0.6Cd0.4Fe2O4 NPs fabricated via sol-gel auto-combustion technic. XRD data affirmed that synthesized do possess a single phase; spinel structure; cubic geometry ferrite in nature. lattice constant (a) was estimated be 8.363 Å crystallite size (t) determined from Deba...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

in this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-ca) to convert carbon dioxide to bicarbonate ion. density functional theory (dft) using b3lyp and ub3lyp functional and three split-valance including 6-31g*, 6-311g** and 6-311++g** basis sets were used to calculate the details of electronic structure and electronic energy of act...

The effects of sciatic nerve crush (SNC) and treatment with Riluzole on muscle activity during unrestrained locomotion were identified in an animal model by analysis of the EMG activity recorded from soleus (Sol) and extensor digitorum longus (EDL) muscles of both hindlimbs; in intact rats (IN) and in groups of rats treated for 14 days with saline (S) or Riluzole (R) after right limb nerve crus...

Beryllium  oxide  (BeO)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  Because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (TL) properties of  the bulk material  in X and γ dosimetry, the applicability of this nanostructure in TL dosimetry was studied  following  irradiation to  the 137 C...

The aim of the study was to use combined longitudinal measurements of soleus (SOL) and gastrocnemii evoked V-wave and H-reflex responses to determine the site of adaptations within the central nervous system induced by 5 wk of neuromuscular electrical stimulation (NMES) training of the plantar flexor muscles. Nineteen healthy males subjects were divided into a neuromuscular electrostimulated gr...
