Linde
In 1877, university Professor Carl von Linde obtained a patent for his refrigerator from the Imperial Patent Office - a patent for something that was not merely an invention, but the result of serious research in the basic laws of physics. Linde went on to found the Linde Company, one of the biggest German Gas and Engineering companies which became one of the models for science based industries. Today, the Linde Group, headquartered in Wiesbaden, Germany, is a global technology company dedicated to gas and engineering, material handling and refrigeration. This book examines the history of this company in the context of the history of technology in industry.

Heart Rate Variability (HRV) Signal Analysis
Open a Window into the Autonomic Nervous SystemQuantifying the amount of autonomic nervous system activity in an individual patient can be extremely important, because it provides a gauge of disease severity in a large number of diseases. Heart rate variability (HRV) calculated from both short-term and longer-term electrocardiograms is an ideal win
The Interface Structure and Electrochemical Processes at the Boundary Between Two Immiscible Liquids
Studies on the electrochemical processes at the interface between two immiscible liquids began a long time ago: they date back to the end of the last century. Such celebrated scientists as Nemst and Haber, and also young A. N. Frumkin were among those who originated this science. Later A. N. Frumkin went a long way in furthering the studies at the Institute of Electrochemistry. The theory of the appearance of potential in a system of two immiscible electrolytes was developed and experimentally verified before the beginning of the thirties. In later years the studies in this area considerably lagged behind those conducted at metal electrodes which were widely used in different industries. In ...

Interfacial Phenomena and the Marangoni Effect
Marangoni (1878), provided a wealth of detailed information on the effects of variations of the potential energy of liquid surfaces and, in particular, flow arising from variations in temperature and surfactant composition. One aspect of this science is seen today to bear on important phenomena associated with the processing of modern materials. The role of the basic effect in technology was probably first demonstrated by chemical engineers in the field of liquid-liquid extraction. Indeed, phenomena attributable to Marangoni flows have been reported in innumerable instances relevant to modern technologies, such as in hot salt corrosion in aeroturbine blades; the drying of solvent-containing paints; the drying of silicon wafers used in electronics; in materials processing, particularly in metallic systems which have been suspected to demonstrate Marangoni flows.
Physics of Fluids in Microgravity
In a microgravity experiment, the conditions prevalent in fluid phases can be substantially different from those on the ground and can be exploited to improve different processes. Fluid physics research in microgravity is important for the advancement of all microgravity scients: life, material, and engineering. Space flight provides a unique laboratory that allows scientists to improve their understanding of the behaviour of fluids in low gravity, allowing the investigation of phenomena and processes normally masked by the effects of gravity and thus difficult to study on Earth. Physics of Fluids in Microgravity provides a clear view of recent research and progress in the different fields of fluid research in space. The topics presented include bubles and drops dynamics, Maragoni flows, diffustion and thermodiffusion, solidfication,a nd crystal growth. The results obtained so far are, in some cases, to be confirmed by extensive research activities on the International Space station, where basic and applied microgravity experimentation will take place in the years to come.
Antiviral Chemotherapy 5
Scientists and clinicians attending the last "New Directions in Antiviral Therapy" conference in late 1994 could hardly have predicted the revolution in the management of patients with HIV infection that has occurred since. Two new classes of antiretrovirals have been licensed, the second-site RT inhibitors and the protease inhibitors; the long in cubation period of active HIV infection, when the infection is clinically latent, is now un derstood to be a period of intense viral replication and turnover of CD4 lymphocytes; measurements of HI V RNA concentration in plasma have been shown to be essential tools for monitoring the course of HIV infection, deciding when to treat, and assessing the...
