Introduction: PMA is known to induce the differentiation of monocytes to macrophages. This agent also increases the killing effect of the monocytes/macrophages through oxidative burst and can be used as a stimulant for oxidative burst assay. The present experimental study was intended to investigate the in vitro effects of PMA on the differentiation, morphological changes, cell adherence and th...

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...

Properties of the neural mechanism responsible for generating the periodic burst of spike potentials in the nine ganglion neurons were investigated by applying brief, single shocks to the four small cells with extracellular electrodes placed near the trigger zones of the small cells. The shock elicited a burst if presented during the latter portion of the silent period, terminated a burst durin...

The burst duration of an all-diode-pumped burst-mode laser is extended to 100 ms and 100 kHz (10,000 pulses) by utilizing dual-wavelength diode pumping. Total energies of 225 J at 10 kHz and 400 J at 100 kHz are achieved during the 100 ms burst period at 1064 nm. This represents an order-of-magnitude increase in the number of pulses compared with prior work, while maintaining similar or higher ...

Optical Bursts Switching (OBS) is a relatively new optical switching paradigm. Contention and burst loss in OBS networks are major concerns. To resolve contentions, an interesting alternative to discarding the entire data burst is to partially drop the burst. Partial burst dropping is based on burst segmentation concept that its implementation is constrained by some technical challenges, beside...

The present study was undertaken to investigate the effects of Zataria multiflora and Eucalyptus globolus essential oils on some haematological parameters and respiratory burst activity in common carp (Cyprinus carpio). 260 fish (30±5g) were randomly distributed in 13 treatment groups each one in three replicates and different doses of essential oils in 16-17ºC were administrated. The fish were...

In this paper, we address the issue of providing differentiated services to IP packets over an optical burst-switched network. QoS is supported by introducing prioritized contention resolution policies in the network core and a new burst assembly technique at the network edge. In the core, contention is resolved through prioritized burst segmentation and prioritized deflection. The burst segmen...

background and purpose: decision-making process in thoracolumbar and lumbar burst fracture (tlbf) patients with thoracolumbar injury severity and classification score (tlics) > 4 is remained controversial. on the other hand, the question is whether that the oswestry disability index (odi) can be use to assess to clinical outcomes in these patients . we aimed to study the correlation between the...

  The effectiveness of θ pattern primed-bursts (PBs) on development of primed-burst (PB) potentiation was investigated in layer II/III of the adult rat visual cortex in vitro. Experiments were carried out in the visual cortical slices. Population excitatory post-synaptic potentials (pEPSPs) were evoked in layer II/III by stimulation of either white mater or layer IV. To induce long-term potenti...
