• Turn on the equipment at the lowest light intensity setting. Sudden high voltage surges can blow bulbs, especially when cold. • Use the equipment at lower light intensity settings as much as possible. • Turn off the bulb or equipment when it is not being used. • Don’t move a device while the bulb is still lit or hot: wait until the bulb has cooled. Even gentle vibrations may cause a hot bulb ...

INTRODUCTION In vivo, most neurons in the main olfactory bulb exhibit robust spontaneous activity. This paper tests the hypothesis that spontaneous activity in olfactory receptor neurons drives much of the spontaneous activity in mitral and tufted cells via excitatory synapses. METHODS Single units were recorded in vivo from the main olfactory bulb of a rat before, during, and after applicati...

Microscopic lymphatics produce nitric oxide (NO) during contraction as flow shear activates the endothelial cells. The valve leaflets and bulbous valve housing contain a large amount of endothelial nitric oxide synthase (eNOS) due both to many endothelial cells and increased expression of eNOS. Direct NO measurements indicate the valve area has a 30-50% higher NO concentration ([NO]) than tubul...

Endwall fillet and bulb structures are proposed in this research to improve the temperature uniformity of pin-fined microchannels. The periodical laminar flow and heat transfer performances are investigated under different Reynolds numbers and radius of fillet and bulb. The results show that at a low Reynolds number, both the fillet and the bulb structures strengthen the span-wise and the norma...

abstract an experiment was conducted to study growth analysis and evaluation of change in simple non- structural carbohydrates (sucrose, glucose and fructose) during bulb formation of ghermez azarshahr , zargan, safid naishaboor and safid qom cultivars in randomized complete block design containing three replications. seeds were sown in nursery in early february and seedlings were transplanted ...

in order to study the effects of different levels of animal manure and bulb weights on growth criteria, yield components, seed yield and essential oil yield of caraway, an experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2012-2013 and 2013-...

introduction drought stress reduces plant growth by affecting various physiological and biochemical processes, such as photosynthesis, respiration, translocation, ion uptake, carbohydrates, nutrient metabolism and growth promoters. garlic (allium sativum l.) is an annual bulb crop that has been cultivated since ancient times and was used as a spice and condiment for many centuries. garlic is an...

SIR, in the recent paper by Gudziol et al. (2009), treatment of chronic rhinosinusitis lead to an increase of the olfactory bulb volume over a 3-month period, and they concluded that this was due to the restoration of olfactory function. In this letter, we point out another factor that may affect olfactory bulb volume: neuroinflammation regulated neurogenesis. The olfactory bulb volume is great...

The expression pattern of aromatase (ARO), the enzyme converting androgens to estrogens, was analyzed in the olfactory bulb of adult male rats and was compared with the distribution of estrogen receptor beta (ERbeta), the main estrogen receptor isoform expressed in this brain region. A strong ARO immunolabeling obtained with a specificity tested antibody was observed in juxtaglomerular neurons ...

BACKGROUND AND PURPOSE Olfactory bulb atrophy is associated with cognitive dysfunction in Parkinson's and Alzheimer's disease, and with major depression. It has been suggested that olfactory bulb atrophy or dysfunction is therefore a marker of neurodegeneration. Multiple sclerosis (MS) is now also recognized as having a significant neurodegenerative component. Thus, the aim of this study was to...
