The paper presents an extension of the mixed Sky-hook and ADD to MagnetoRheological dampers. Firstly, a semi-active automotive suspension equipped with a nonlinear Magneto-Rheological damper is introduced. The interest of this nonlinear model is that the bi-viscous and hysteretic behaviors of MR dampers can be taken into account in the controller design. Hence, the designed controller is more a...

Pipe vibration is often excited in the deep ocean by ship motions, wave forces and vortex shedding. Elastic joints along the pipe are modeled in an attempt to move the resonance frequencies away from the pipe system. The numerical examples focus on the investigation of single and multiple elastic joints along a long pipe and their effect on three-dimensional (3-D) nonlinear coupled pipe respons...

A 67-year-old man presented with leg edema. Laboratory data showed elevated blood glucose and carbohydrate antigen (CA) 19-9 levels, and anemia. Further imaging studies revealed a relatively clear-margined tumor totally occupying the main pancreatic duct (MPD) from the head to the tail of the pancreas (maximum diameter 10 cm) without mucin hypersecretion. Total pancreatectomy with splenectomy a...

Passive strategies based on the introduction of energy dissipating devices into the structures have received considerable attention in recent years. Within this framework, as reliable and cheap energy-dissipation devices, viscous fluid dampers have been largely used in seismic protection of industrial machines, technical equipments, buildings and bridges. Since the versatility of this passive p...

Behavioral sensitization is defined as the subsequent augmentation of the locomotor response to a drug following repeated administrations of the drug. It is believed to occur due to alterations in the motive circuit in the brain by stressors, central nervous system stimulants, and similar stimuli. The motive circuit (or mesocorticolimbic system) consists of several interconnected nuclei that de...

The sharp increase of the prescription of methylphenidate (MPD) in hyperactive children in recent years is a matter of increasing uneasiness among professionals, parents and politicians. There is little awareness of treatment alternatives. The purpose of this prospective trial was to assess the efficacy of homeopathy in hyperactive patients and to compare it MPD. The study was performed in a pa...

Dioscoreaceae, a kind of yam plant, has been recommended for treatment of chronic inflammatory conditions. However, the mechanisms are poorly defined. Methyl protodioscin (MPD) is one of the main bioactive components in Dioscoreaceae. Here, we aim to determine the mechanisms by which MPD ameliorates intestinal inflammation. Surgical intestinal specimens were collected from inflammatory bowel di...

In this paper the performance of Artificial Neural Networks (ANNs) and Adaptive NeuroFuzzy Inference Systems (ANFIS) in simulating the inverse dynamic behavior of MagnetoRheological (MR) dampers is investigated. MR dampers are one of the most applicable methods in semi active control of seismic response of structures. Various mathematical models are introduced to simulate the dynamic behavior o...

School teaching is regarded as a stressful occupation. The present study aimed to compare the likelihood of having minor psychiatric disorders (MPD) among school teachers with that among civil servants, and to investigate what factors were specifically associated with MPD in teachers. We conducted a questionnaire-based survey of 403 teachers employed at state schools and 611 civil servants as a...

We previously reported that the lower activity of mevalonate pyrophosphate decarboxylase (MPD) was caused by the reduced amount of this enzyme in stroke-prone spontaneously hypertensive rat (SHRSP) by immunoblot analysis using 20,000 x g supernatant containing cytosol and microsomes. A recent study showed that at least three different subcellular compartments, including peroxisomes, are involve...
