Spectrally resolved laser-induced fluorescence (LIF) with one-dimensional spatial imaging was investigated as a technique for detection of trace concentrations of nitric oxide (NO) in high-pressure flames. Experiments were performed in the burnt gases of premixed methane/argon/oxygen flames with seeded NO (15 to 50 ppm), pressures of 10 to 60 bar, and an equivalence ratio of 0.9. LIF signals we...

Solar thermochemical conversion is an effective method for solar energy storage, and propane dehydrogenation one popular technology to generate propylene hydrogen, while the high temperature required in reaction limits its efficiency utilization. In this research, a solar–driven hydrogen permeation membrane reactor system proposed efficiently generating pure mild range, which can decrease heat ...

The analysis of the first two years of OGLE data revealed 9 microlensing events of the galactic bulge stars, with the characteristic time scales in the range 8.6 < t0 < 62 days, where t0 = RE/V . The optical depth to microlensing is larger than (3.3 ± 1.2) × 10, in excess of current theoretical estimates, indicating a much higher efficiency for microlensing by either bulge or disk lenses. We ar...

The Singapore Mass Rapid Transit (MRT) project started compressed air work in Oct 1984. Eleven km of underground tunnels out of 20 km were built using this method. Cases of decompression sickness (DCS) arising from compressed air work are rare with working pressures less than 1 bar gauge. However, there were 10 cases of DCS in the MRT project who were exposed to less than 1 bar pressure. The au...

This novel, competitive immunoassay simultaneously detects seven drugs of abuse in urine. A urine sample is placed in contact with lyophilized reagents, the reaction mixture is allowed to come to equilibrium (10 min), and then the whole mixture is applied to a solid phase that contains various immobilized antibodies in discrete drug-class-specific zones. After a washing step, the operator visua...

In this paper, we have developed a new prototype of 0.5 hp induction motor with reduced slots in rotor bar and stator core in comparison to the conventional induction motor. The conventional induction motor usually uses 30 slots of aluminum rotor bar and 36 slots in the stator core. In our developed prototype, we used 10 slots of copper rotor bar and 24 slots in the stator core. In order to eva...

DOMINO, E. F. AND M. P. LUTZ. Tolerance to the effects of daily nicotine on rat bar pressing behavior for water reinforcement. PHARMAC, BIOCHEM. BEHAV. 1(4) 445-448, 1973.-The effects of daily nicotine tartrate given IP in a dose of 0.25 mg/kg twice a day for 15 days was studied on bar pressing behavior for water reinforcement in the rat. A modified FR t 5 schedule was used. Nicotine injections...

An equation of state is presented for liquid iron based on published ultrasonic, thermal expansion, and enthalpy data at 1 bar and on pulse-heating and shock wave compression and sound speed data up to 10 Mbar. The equation of state parameters, centered at 1 bar and 1811 K (the normal melting point of iron), are density, P0 = 7019 kg/m 3 isentropic bulk modulus K so 109 7 GPa, and the firstand ...

an aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. in this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial tfc (thin film composite) polyamide nanofilter. the effects of ph (6.5-8.5), pressure (4-10 bar), concentration of to...
