    A precise calibration system for high-resolution visible-laser spectroscopy (1989)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 60 (1989), S. 1003-1007

    Notes: A method for calibrating high-resolution laser spectra in the visible is described. The system is based on an evacuated Fabry–Perot étalon whose cavity length is servolocked to a stabilized HeNe laser; the absolute order number of the fringe at the HeNe frequency is known and the free spectral range can be determined with high accuracy. For absolute-frequency measurements the order number of a transmission fringe is obtained from a commercial wavemeter (whose accuracy is sufficient to identify the fringe); the absolute frequency is then the HeNe frequency multiplied by the ratio of the "unknown'' order number to the "lock-point'' order number. The long-term frequency reproducibility of the system is better than 25 MHz. Small-frequency splittings such as molecular hyperfine intervals can be measured to ±1 MHz, while large-frequency intervals (of the order of 500 GHz) are consistent to better than 10 MHz.

    CO2 laser stabilization using an external cavity locked to a reference HeNe laser (1986)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A method is described for stabilization of a cw CO2 laser by locking it to a modulated external cavity which is locked to a HeNe reference laser. This avoids the necessity of modulating the CO2 laser. Stability values of a few tens of kHz on the microsecond and minute time scales have been achieved.

    A laser-induced fluorescence study of bands of the red system of gaseous CoO: Evidence for a 4Δi ground state (1987)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 86 (1987), S. 5231-5238 
    Details
    ISSN: 1089-7690

    Topics: Physics , Chemistry and Pharmacology
    Notes: Three bands of the "red'' system of gaseous CoO have been rotationally analyzed using laser-induced fluorescence techniques. The available evidence indicates that the lower levels are the Ω=7/2 and 5/2 spin–orbit components of a 4Δi electronic state, which is assigned as the ground state of the molecule. The cobalt nuclear hyperfine splittings are small in the ground state, which suggests that no unpaired electron in a σ molecular orbital derived from the Co 4s atomic orbital is present, so that the electron configuration is presumably σ2δ3π2; the ground state bond length (r0) is 1.631 A(ring). The upper electronic levels are heavily perturbed, both rotationally and vibrationally, and their hyperfine structures, though following case (a) behavior, are large and irregular. This work on CoO completes the determination of the ground state symmetries and bond lengths for the whole series of the 3d transition metal monoxides; some comparisons for the members of the series are given.

    Culture of Nile tilapia, Oreochromis niloticus (L.), at three stocking densities in outdoor concrete tanks using drainage water (1989)

    Notes: Abstract. Effects of stocking density on water quality and on the growth, survival and food conversion of Oreochromis niloticus (Linnaeus) were evaluated. Fingerlings of tilapia (average weight 40.25 ± 94 g) were stocked in six 3.75-m3 concrete tanks at 16, 32 and 42.6/m3 and reared for 164 days. A water flow rate of 1 l/min/kg fish biomass was maintained in all the tanks. The growth rate was inversely related to stocking density with mean weights of 337.25g, 327.0g and 323.5g at the low, medium and high densities respectively. At harvest, standing crop biomass averaged 5.36 kg, 10.44kg and 13.24kg for the three densities. The respective food conversion ratios (FCR) were 1.85, 1.88 and 1.95, while the survival rates were 99.2, 99.6 and 95.9%. However, the survival rate, growth rate and food conversion efficiencies were not significantly different at the three stocking densities. Water quality did not deteriorate in different tanks as the oxygen was continuously replenished and metabolites and waste products removed by the water flowing through the tanks. These data suggest that culture of tilapia at a density of 42.6/m3 and production of 13.24 kg/m3 in 164 days with a production of 18–20 kg/m3 in a growing season (April-October) of 210 days is possible using the drainage water in flow-through water systems.

    The number of frog sciatic axons increases continually during body growth (1988)

    Notes: Summary Frog sciatic nerves show a continuing addition of new myelinated and nonmyelinated fibers with body growth. Along with increases in fiber number there are also marked changes in axon calibers and in the relative thickness of the myelin sheaths. Our data show that frog nerves, as opposed to mammalian nerves, are composed of fibers of different ages, stages of growth and stages of myelination.

    Mechanism of the congestion of lymph nodes induced by ellagic acid in rats (1987)

    Notes: Abstract Intravenous injection of ellagic acid (EA, 30 mg/Kg), an activator of the Hageman factor, induced congestion of lymph nodes and dilatation of the spleen in rats. The dilatation of the spleen was inhibited by heparin, thrombin, defibrase, clocoumarol. lambda carrageenan, SBTI, PCR 4099 and CCI 17810. The congestion of lymph nodes was inhibited by heparin, thrombin, defibrase, clocoumarol, SBTI, lambda carrageenan, aspirin, indomethacin and ketoprofen, phentolamine and hexamethonium. Thrombin, defibrase, lambda carrageenan did not induce any congestion of the lymphoid tissues. These results suggest that the dilatation of the spleen induced by ellagic acid would result from blood coagulation, platelet stimulation and kinin formation. The congestion of lymph nodes would depend on kinins, blood coagulation and prostaglandins. The activation of Hageman factor in acute inflammatory reactions could mediate the early congestion of lymph nodes.

    Studies on the vascular and hematological changes induced by ellagic acid in rats (1987)

    Topics: Medicine
    Notes: Abstract We compared the major changes induced by ellagic acid (EA), a Hageman factor activator, in normal rats and in kininogen-deficient Brown Norway rats. In normal rats, large doses of EA induced a congestion of lymph nodes, spleen and liver, a prolongation of activated partial thromboplastin time, the consumption of prekallikrein, high molecular weight kininogen and fibrinogen, as well as the stimulation of platelets with their accumulation in lungs, liver and spleen. A systemic hypotension of long duration was also observed. The fibrinogen consumption, the thrombocytopenia and the lengthening of activated partial thromboplastin time were dose-dependent. In kininogen-deficient rats, EA induced only a minimal congestion of lymphoid tissues, the accumulation of platelets in lungs, a decrease of plasma fibrinogen and a short-lasting hypotension. It is concluded that the vascular changes induced by blood coagulation with ellagic acid resulted mainly from kinin formation.
