Question: In the microwave portion of the electromagnetic spectrum, does it make a difference in terms of how much energy is scattered by snow crystals, whether or not they have a particular orientation in regards to each other? Put in another way, in calculating the amount of energy that is transferred from the ground, through the snowpack, can it be assumed that all of the crystals in a snowp...

Invasive mould disease is a growing threat for immunocompromised patients. The optimum time to use mould-active antifungal agents is much debated. Current approaches to antifungal prophylaxis, early treatment (empirical and pre-emptive therapy) and treatment of documented mould infections in onco-haematology patients are discussed.

Burn-on and penetration defects in steel casting are principally caused by localised overheating of the sand mould or cores. Such overheating can cause liquid metal to compromise the mould surface and entrain onto the surface of the mould. A method has been developed to predict likely burn-on and penetration defect locations as part of a standard casting simulation. The method relies on determi...

This article is focused on the optimization of heat radiation intensity across the surface of an aluminium mould. The mould is warmed by infrared heaters located above the mould surface, and in this way artificial leathers in the automotive industry are produced (e.g. the artificial leather on a car dashboard). This described model allows us to specify the location of infrared heaters over the ...

Little information has been available on the shifts in the microbial community in decaying fallen logs during critical periods in cold forests. Minjiang fir (Abies faxoniana) fallen logs in decay classes I-V were in situ incubated on the forest floor of an alpine forest in the eastern Tibet Plateau. The microbial community was investigated during the seasonal snow cover period (SP), snow thawin...

A large number of interesting Co (II) complexes with macrocyclicligands have been synthesized and the recognition its as important bioactive compounds in vitro vivo has aroused growing interest these agents potential drugs for therapeutic use various diseases. Numerous available information on their bioinorganic properties mode action several biological systems, combined new possibilities impos...

Aspergillus, a genus of spore forming fungi found worldwide, affects the respiratory tract in many ways [1, 2]. The spores of this ubiquitous mould are dispersed by wind in the atmosphere and inhalation is the primary route of access in almost all forms of aspergillosis. The spectrum of Aspergillus-associated respiratory disorders comprises three well defined clinical categories (table 1): alle...
