BACKGROUND Transforaminal epidural steroid injection is one of the effective treatments in managing radicular pain. There have been some prospective studies on the depth to the epidural space with the transforaminal approach. However, there have been no studies about the depth in Asians, especially Koreans. This study was carried out in order to evaluate the depth to the epidural space and the ...

melatonin, a pineal gland secreted hormone has different effects on mammalian physiology. recently, specific receptors of melatonine have been found in the central nervous system and spinal cord of rabbits. l - theanine is a unique amino acid in the tea plant ( camellia sinensis ). the effects of this amino acid is based on increasing gaba and dopamine levels in the brain and has a weak effect ...

Abrasive wear resistance of injection molded polycarbonate (PC) and polycarbonate + zinc oxide nanocomposites containing 0.5 wt% ZnO nanoparticles was determined as a function of the sliding direction with respect to injection flow. First we have performed single scratch testing under progressively increasing the load applied. Then sliding wear testing consisting of 15 successive scratches alon...

Dear Editor, This letter concerns about the security problem of underwater cyber-physical system (UCPS) for depth-keeping task in vertical plane. A dynamic parametric model UCPS with ocean currents and hydrostatic is considered. With intelligence controller, objective function a zero-sum game between attacker controller introduced. The destroys by injecting designed false data into system. Comp...

Chloropicrin (CP) is highly volatile and may pose strong exposure risks for humans and the environment. A gelatin capsule formulation was developed to reduce atmospheric CP emissions and to improve application safety. The objective of this study was to determine the distribution, atmospheric emissions, and soil residual of CP after application in gelatin capsules to soil columns. Two treatments...

Dike emplacement in volcanic rift zones is often associated with the injection of “bladelike” dikes, which propagate long distances parallel to the rift, but frequently remain trapped at depth and erupt only near the tip of the dike. Over geologic time, this style of dike injection implies that a greater percentage of extension is accommodated by magma accretion at depth than near the surface. ...
