introduction: previous studies have been shown that low frequency stimulation (lfs) has an inhibitory effect on kindling acquisition. however, the mechanism of this effect has not been completely determined. in the present study, the effect of lfs of the perforant path on seizures induced by rapid perforant path kindling was investigated. methods: animals were kindled by electrical stimulation ...

one of the world's major mineral dust source regions lies along the border between iran and afghanistan. in this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region. the presence of alow-level jet east of the seistan mountains is documented here for the first time. the jet exists mainly from may toseptember and has a core at 850 mb. ma...

this study was conducted to evaluate the effects of inoculation of homo-fermentative lactic acid bacteria(lab) on ensiling characteristics and nutritive value of low dry matter corn silage (ldmcs). corn foragewas harvested at milk stage (22.8 ± 0.9% dm), chopped at theoretical length of cut (tlc) 2.5 cm, and stored in eighteen 3.8 l mini silos for each treatment. the following treatments were u...

the current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. for this purpose, some experiments including hardness test, non-destructive test (ndt), metallography, and fractograpghy are conducted. the microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (sem). the microstructural studies show that t...

propose: standard electroporation and electrochemotherapy caused the endothe- lial cell permeability and reduction in tumor blood flow. the effects of low voltage and high frequency electroporation on the endothelial cells permeability and viability were expected. therefore, the propose of present study was to evaluate the effect of electroporation with bleomycin or alone on viability and perme...

this article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (ldpe/starch) by infrared spectroscopy: films of ldpe/starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°c,and buried in the soil of public dump during 3...

conclusions lumbar discectomy improves both the physical and mental health subscale of the quality of life in patients with chronic disc herniation. results physical and mental health scores of patients significantly improved after 6 and 12 months of lumbar discectomy. the mean improvement in physical health scores was significantly higher in female patients than in male patients. however, the ...

in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

passive smoking (ps), a well-known health risk, is the major source of indoor pollution. there is some inconsistent evidence that ps during pregnancy may increase the risk of low birth weight. the aim of the present study was to determine the effects of ps exposure during pregnancy on weight, length and cranial circumference at birth of babies born to women who have described themselves as nons...
