A method for semi-continuous (10 min time resolution) PM2.5 nitrate and sulfate measurements, based on the humidified impaction with flash volatilization design of Stolzenburg and Hering (Environ. Sci. Technol. 34 (2000) 907), was evaluated during the Pitt ...
Under present-day climatic conditions the air content of ice shows a high sensitivity to the atmospheric pressure and hence to the elevation at the surface of the ice sheet. This observation has been used to infer past ice sheet thickness variations of Ant ...
Since the yeast Phaffia rhodozyma was first described some 35 yr ago, there has been significant interest in the development of com. processes to exploit its ability to produce carotenoids (.apprx.80% astaxanthin). However, the optimal conditions for carot ...
The accretion of the terrestrial planets from asteroid collisions and the delivery to the Earth of martian and lunar meteorites has been modelled extensively(1,2). Meteorites that have experienced shock waves from such collisions can potentially be used to ...
The end of the Last Glacial Maximum (Termination I), roughly 20 thousand years ago (ka), was marked by cooling in the Northern Hemisphere, a weakening of the Asian monsoon, a rise in atmospheric CO 2 concentrations and warming over Antarctica. The sequence ...
In a bog site in way of paludification, a pine stand is declining, which presently is an infrequent phenomenon on the Swiss Jura scale. A transect was positioned in the bog, from the external and driest part (pine-spruce stand) towards the central and wett ...
Optimal management strategies for a group of bridges that may incur damage from flooding during a 15-year period were determined using three approaches, and then the strategies were compared. The three approaches are the supply and demand system approach a ...
This case is a short (2-page) follow-up to the A-case: IMD-6-0252 and should be used together with it. The case relates the story from July 2001 to July 2002, illustrating the complications encountered in finalizing the outsourcing agreement. It summarizes ...
An estimate of the rate of increase in numerical simulation grid sizes with time is obtained by counting the grids (measured in terms of number of node points) reported in the nine volumes of an established proceedings on the numerical modeling of solidifi ...
[1] During the last 5 years, information on the regional tropospheric ozone levels over the eastern Mediterranean has become available but was confined to measurements at ground level. Here available information is expanded with measurements at two more ru ...
