A. ELECTRON DENSITY MEASUREMENTS IN CONTINUOUS ARGON ION LASERS We are continuing our studies of the electron density in argon ion laser discharges. Several improvements have been made in our diagnostic equipment since our last report. l We present some preliminary results of measurements performed on continuous argon discharges. 1. Steady-State Discharge Measurements Figure VII-1 is a block di...

A recent issue of JECT contained two articles on air bubbles in the cardiopulmonary bypass (CPB) circuit and an article on the routine use of hyperoxia during CPB (1–3). Interestingly, these two subjects are related in a way that perfusionists do not commonly associate. The article by Dickinson et al. (1) and the commentary by Willcox and Mitchell (2) suggested that gaseous emboli passing to th...

HI observations have revealed in several shell galaxies the presence of gaseous shells slightly displaced from the stellar shells radially, in the outward direction. We propose a mechanism to form this gaseous shells, based on the well-known phase-wrapping process of the companion matter in a merger, with nearly radial orbits. The mechanism relies on the existence of a clumpy interstellar matte...

As the likely birthplaces of planets and an essential conduit for the buildup of stellar masses, inner disks are of fundamental interest in star and planet formation. Studies of the gaseous component of inner disks are of interest because of their ability to probe the dynamics, physical and chemical structure, and gas content of this region. We review the observational and theoretical developme...

The possibility of a gaseous halo stream which was stripped from the Sagittarius dwarf galaxy is presented. The total mass of the neutral hydrogen along the orbit of the Sgr dwarf in the direction of the Galactic Anti-Center is 4 − 10 × 10 6 M ⊙ (at 36 kpc, the distance to the stellar debris in this region). Both the stellar and gaseous components have negative velocities in this part of the sk...

This paper describes a study that gives a consideration to change fuel source for electriccity generator from gasoline to combustible gas. A gaseous fuel conversion technology is presented and its performance is compared with gasoline. In the experiment, two types of load were tested, resistive and resistive-inductive. By using both fuels mostly the power factor (Cos φ) of resistive-inductive l...

1. Ischaemic brain injury is a leading cause of death and disability in many countries. However, the pathological mechanisms underlying ischaemic brain injury, including oxidative stress, calcium overload, excitotoxicity and neuronal apoptosis, are perplexing and this makes it difficult to find effective novel drugs for the treatment of the condition. 2. Recently, gaseous molecules such as nitr...
