1First, two liquids (water and water with dye) are injected in the chamber and mix until a desired pressure is achieved (from 1 up to 4 atmospheres). Then, gas (compressed air) is introduced in order to decrease the density of the mixture at a given pressure. When the mixture is ready, it is heated until a desired temperature (from ambient temperature up to 150 oC), at this precise moment, a va...

A review of the literature reveals considerable evidence to support the suggestion that vegetative surfaces remove particulate matter from the atmosphere. Preliminary observations of the leaf surfaces of an important urban tree indicate the presence of numerous particulate contaminants. In view of the medical importance of fine particles in urban atmospheres, it is important to assess the effic...

The cquatioii for steady two-dimcnsional mountain w a ~ c s is csprcsscd in the isentropic coordinates. An elliptic equation for thc fiiiitc ainplitudc vertical motion ficld is solved by a numerical marching schemc in atmospheres with varying shcar and stability.

RECENTLY a great deal of attention has been focused on the problem of carbon dioxide accumulation during anaesthesia (Stead et ah, 1953; Harbord, and Lucas, 1953). A number of articles have appeared describing investigations on the actual figures for " alveolar air " or arterial carbon dioxide tensions found during anaesthesia. Ringrose et al. (1950) developed a carbon dioxide indicator showing...

Oxygen binding by trout Hb IV has been investigated as a function of pH up to 10 atmospheres (1 MPa) of pure O2. The results bring out an extreme proton-oxygen linkage, which gives rise to a Root effect. They are discussed in relation to the function of the hemoglobin as an oxygen pump. The system is of special interest as providing a prototype of a macromolecule acting as a transducer by coupl...

A planar surface acoustic wave on a solid substrate and its radiated sound into a static liquid drop produce time-averaged, exponentially decaying acoustic and electric Maxwell pressures near the contact line. These localized contact-line pressures are shown to generate two sequences of hemispherical satellite droplets at the tens of microns and submicron scales, both obeying self-similar expon...

Several levels of control of elongation rate are revealed through the detailed study of responses of the Nitella internode to abrupt shifts in turgor. The immediate response, which apparently reflects the physical state of the cell, is approximately described by the equation r = (P - Y)m where r is rate, P is pressure, Y is the wall's yielding threshold, and m is related to the wall's apparent ...

Whistler mode instability in interplanetary space at 1AU(Astronomical Unit) is investigated using an anisotropic Lorentzian Kappa distribution with perpendicular AC electric field for relativistic plasma. The method of characteristic solutions using the perturbed and unperturbed particle trajectories have been used to determine the perturbed distribution function. The conductivities and dielect...

Darwin is one of the most challenging space projects ever considered by the European Space Agency ESA Its principal objectives are to detect Earth like planets around nearby stars and to characterise their atmospheres Within the frame of the Darwin programme the European Space Agency ESA and the European Southern Observatory ESO intend to build a ground based technology demonstrator Such a grou...

Conditional slantwise instability (CSI) is observed to occur in saturated, statically stable atmospheres where the horizontal wind increases in magnitude and veers with height. A complete background on CSI may be found in the compendium by Schultz and Schumacher (1999). Numerous studies in the midlatitudes (e.g. Sanders and Bosart 1985, Moore and Blakely 1988, Weismueller and Zubrick 1998) have...
