rice is the world's most important food crop. to decrease the damage of  rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...

Abstract The simulation and corrosion conduction of anti-acid brick in high temperature particle abrasion circumstances were tested with scanning electron microscopic, mechanical compression, X-ray diffraction. results showed the strength degradation rates Anti-acid 7.0% 17.8% different high-temperature acid conditions. water vapor environment permeated into after eroding crystal structure surf...

This study aimed to investigate the analgesic effect of substance P (SP) in an animal model of neuropathic pain. An experimental model of neuropathic pain, the chronic constriction injury (CCI) model, was established using ICR mice. An intravenous (i.v.) injection of SP (1 nmole/kg) was administered to the mice to examine the analgesic effects of systemic SP on neuropathic pain. Behavioral test...

in this study , the physical and mechanical properties of polypropylene composites reinforced with bagasse alkaline-sulfite-anthraquinone, soda-anthraqouinone, monoethanolamine-anthraquinone chemical pulps and mechanical pulp (cmp) known as pulp-plastic compostes (ppc) were investigated and the results were compared among ppcs and with polypropylene composites reinforced with bagasse flour know...

Spinal glial and proinflammatory cytokine actions are strongly implicated in pathological pain. Spinal administration of the anti-inflammatory cytokine interleukin (IL)-10 abolishes pathological pain and suppresses proinflammatory IL-1β and tumor necrosis factor alpha (TNF-α). Drugs that bind the cannabinoid type-2 receptor (CB(2)R) expressed on spinal glia reduce mechanical hypersensitivity. T...

Here we investigated the central processing mechanisms of mechanical allodynia and found a direct excitatory link with low-threshold input to nociceptive neurons. Experiments were performed on male Sprague-Dawley rats weighing 230-280 g. Subcutaneous injection of interleukin 1 beta (IL-1β) (1 ng/10 µL) was used to produce mechanical allodynia and thermal hyperalgesia. Intracisternal administrat...

In the recent decades, metallic nanoparticles have been widely used in various industries due to their wide range of applications1, 2. Nanoparticles have unique electrical, physical, chemical and optical properties3. Nowadays copper is highly regarded due to its specific catalytic, optical, electrical and mechanical characteristics4. Copper nanoparticles have great applications as heat transfer...

this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...

silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...
