This paper analyses current trends in information management, considers the problems they involve, and suggests some strategies for tackling these problems. The current goal is integrated, personalised information systems, to be reached via artificial intelligence. The argument is that the extent to which this goal can be achieved is limited because these systems are intrinsically heterogeneous...

The liver is famous for its strong regenerative capacity, employing different modes of regeneration according to type and extent of injury. Mature liver cells are able to proliferate in order to replace the damaged tissue allowing the recovery of the parenchymal function. In more severe scenarios hepatocytes are believed to arise also from a facultative liver progenitor cell compartment. In hum...

The interaction of anticancer chalcone [AMC, 1-(4'-aminophenyl)-3-(4-N,N-dimethylphenyl)-2-propen-1-one] with DNA has been explored using electrochemical, spectroscopic and viscometric techniques. A shift in peak potential and decrease in peak current were observed in cyclic voltammetry and hypochromism accompanied with bathochromic shift were noticed in UV-Vis absorption spectroscopy. These fi...

The equivalence of the Ampere and Biot-Savart force laws in magnetostatics is examined by considering the difference in the forces predicted by the two laws. The conditions under which this force difference vanishes are discussed, with special reference to the question of convergence of the integrals involved. The conclusions are that a complete current distribution exerts forces, which are the...

OBJECTIVES The purpose of this study was to compare the assessment of myocardial perfusion by myocardial parametric quantification (MPQ) with technetium-99m sestamibi single-photon emission computed tomographic (SPECT) imaging in humans. BACKGROUND Accurate visual interpretation of myocardial contrast echocardiographic (MCE) images is qualitative and requires considerable experience. Current ...

Situs Inversus, a rare congenital anatomical abnormality although is not directly related to Sudden Death. However, 3-5% of people with Situs Inversus have associated functional heart defect & 25% have an underlying condition i.e. Primary Ciliary Dyskinesis presenting as Kartagener's Syndrome; are prone to Sudden Death. Two cases of Situs Inversus on which medico-legal autopsy was conducted are...

The ability of firms to adapt to changing markets and technology is a fundamental topic both in strategic management and marketing literature. The focus of this paper is to study how firms adapt to their environments and create superior market orientation. We hypothesize specific relationships between market adaptation and market orientation. Moreover, we analyze the moderating effects of a fir...

In his comment, Heikkila (1998) raises a number of objections to the concept of time-varying magnetic reconnection, and magnetic reconnection in general, which was obviously the basis of our paper on the longitudinal extent of magnetopause reconnection pulses (Lockwood and Davis, 1996). These objections are invalid. Much of the problem arises because Heikkila relies heavily on a simple electric...

Should a “price squeeze” constitute anticompetitive conduct requiring investigation under the antitrust laws? A price squeeze occurs when a vertically integrated firm supplies an input to its downstream competitors at a price that generates a profit margin so low that the competitors exit the downstream market. I ask whether it is sensible to try to use antitrust laws to prevent such conduct or...
