ISSN: 0392-6737Keywords: Optical properties and materialsSource: Springer Online Journal Archives 1860-2000Topics: PhysicsDescription / Table of Contents: Riassunto In questo lavoro si presentano recenti misure FTIR relative allo stretching del legame Si−O ed al bending dei legami Si−O−Si O−Si−O in film amorfi di biossido di silicio. Si paragonano i risultati ottenuti per film cresciuti secondo differenti tecniche: APCVD, LPCVD, PACVD ed, infine, ossidazione termica. Si studia inoltre l’effetto dell’annealing termico sullo spettro ottico di assorbanza.Notes: Summary In this work we report new FTIR absorbance measurements due to Si−O stretching bond, Si−O−Si and O−Si−O bending bonds of silicon dioxide amorphous films. We compare the optical results obtained from films grown by APCVD, LPCVD, PACVD and thermal oxidation techniques. The effect of thermal annealing on optical obsorbance structures has been studied.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1793Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Intertidal algae are exposed to a highly variable photic regime because of crashing waves. We measured photosynthetic rate of whole fronds of the seaweeds Postelsia palmaeformis (Ruprecht) (at Bodega Marine Laboratory, 1991) and Hedophyllum sessile (Setchell) (Phaeophyceae) (at Friday Harbor Laboratories, 1990) in flashing and steady-state photosynthetically active radiation (PAR) of equal irradiance, using a recirculating metabolism chamber designed to minimize the thickness of diffusional boundary layers on the surfaces of algal tissues. The dimensionless ratio of photosynthetic rate under flecking PAR (Pfleck) and the sum of photosynthetic rate under steady state PAR (Ps) of high and low irradiance was computed for lightfleck periods from 0.2 to 100 s. Pfleck:Ps is a measure of the light-flash utilization-efficiency in flashing light, and was greater than unity at periods between lighflecks of 2 to 30 s, with a peak at 10 s. We used a novel optical fiber irradiance meter to measure PAR incident on fronds of P. palmaeformis as they were washed about by waves breaking in the intertidal zone, and compared the light records to that obtained by a stationary sensor under the canopy. PAR flashing period was closely correlated with the period of breaking waves in stands of P. palmaeformis. We estimated the seasonal spectrum of period between light flashes in stands of this species by examining the spectral density of ocean waves at Bodega Marine Laboratory, Bodega Bay, California. The wave spectrum peaks at a period (10 s) where light-flashes may theoretically enhance the light-flash utilization-efficiency of seaweeds. We calculate that the enhanced light-flash utilization-efficiency wrought by wave-induced light-flashes may contribute to significant gains in primary productivity of these macroalgae under some conditions.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1912Keywords: Dental pulp ; Noradrenaline ; Extraneuronal uptake1 ; O-methylationSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary The extraneuronal removal and disposition of noradrenaline in rabbit dental pulp was examined in view of earlier evidence that the tissue possessed an extra-neuronal uptake process resembling neuronal uptake1. Pulp, which had been depleted of sympathetic nerves by homolateral superior cervical ganglionectomy, was incubated in vitro with 3H-noradrenaline in low concentrations (0.025 or 0.18 μmol/l). When the metabolising enzymes (monoamine oxidase, catechol-O-methyl transferase) were active, 3H retention by the denervated pulp, as indicated by the 3H content after the tissue had been washed for 30 min following incubation with 3H-noradrenaline, was less than 30% of that of the innervated pulp. When the enzymes were inhibited, retention rose to approximately 30% of that of the innervated pulp. Analysis of the time course of the 3H efflux indicated that the 3H-noradrenaline in the denervated pulp had accumulated in a single compartment characterised by a t1/2 for efflux of several hours. Accumulation did not occur under Na+-free conditions, and was inhibited by desipramine (IC50 〈 0.03 μmol/l) and by substrates of neuronal uptake1. Mean IC50, values of the latter were very similar to those for inhibition of neuronal uptake1 and comprised (in μmol/l): (+)amphetamine (0.29), dopamine (0.31), tyramine (0.39), (−)noradrenaline (0.70), (−)adrenaline (1.50), 5-hydroxytryptamine (20) and bretylium (35). Uptake2 inhibitors were less active (O-methyl isoprenaline, IC50 = 60 μmol/l) than uptake1 inhibitors, or were without inhibitory effects at the concentrations tested (hydrocortisone, 210 μmol/l; 2-methoxy oestrone, 10 μmol/l). The effects of Na+ omission, of (+)amphetamine, and of O-methylisoprenaline on 3H-normetanephrine formation (measured in the absence of catechol-O-methyl transferase inhibition) matched their effects on 3H-noradrenaline accumulation. The results provide strong support for the presence in rabbit dental pulp of extraneuronal uptake1 which is linked with catechol-O-methyl transferase in the removal of noradrenaline.Type of Medium: Electronic ResourceURL: -
