jt\. amebic abscesses of the right lobe of the liver, comparatively little attention so far has been given to amebic necroses of the left lobe. The reason for this paucity of clinical observations is illustrated by Munk's remark (1): "... the x ray symp-tomatology of amoebic hepatitis is limited in the main to indirect signs on the right half of the diaphragm and the right lower lung field. " (Amoebic hepatitis affecting the left liver lobe exclusively is not included in this paper, as no definite cases have been encountered.) Single case reports are available from North Africa and from India (2, 3). La-mont and Pooler (4), and Paul (5) have re-cently given attention to problems con-nected with left lobe abscesses in their papers on large series of amebic abscesses of the liver. We have found amebic abscesses of the left lobe of the liver, though comparatively rare, to be a well defined clinical entity, distinct from right lobe abscesses. The knowledge of this syndrome facilitates an early diagnosis leading to timely and effi-cient treatment in most cases, while a high mortality ensues in protracted cases, and after complications have developed. In this paper an attempt will be made to differentiate the two types of liver ab-scesses as well as to consider the differen-tiation of left lobe abscesses from diseases affecting neighboring structures of the left lobe outside the liver. The study is based on clinical, radiologi-cal, and laboratory observations in eight patients. Five were admitted to the Asaf

Despite the very extensive literature on dropout from higher education, much remains unknown about the nature of the dropout process. In large measure, the failure of past research to delineate more clearly the multiple characteristics of dropout can be traced to two major shortcomings; namely

Reigning measures of psychological well-being have little theoretical grounding, despite an extensive literature on the contours of positive functioning. Aspects of well-being derived from this literature (i.e., self-acceptance, positive relations with others, autonomy, environmental mastery

from an extensive literature essential principles that ensure stability and use these to present a concise characterization of most of the model predictive controllers that have been proposed in the literature. In some cases the finite horizon optimal control problem solved on-line is exactly

the perspective of study scope, the current literatures are distinguished into four categories on

theory, cosmology, particle physics, astrophysics and condensed matter physics. No details are given, but references are provided to guide the interested reader to the literature. The present state of knowledge is summarized in a list of 35 key results on topics including the hamiltonian and path

is developed that unifies many of the methods which have been proposed over the last few decades in several different scientific disciplines. Novel extensions to the existing methods are also proposed. We show in particular how to incorporate local linearisation methods similar to those which have previously

Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3

In this paper we compare the performance of descriptors computed for local interest regions, as for example extracted by the Harris-Affine detector [32]. Many different descriptors have been proposed in the literature. However, it is unclear which descriptors are more appropriate and how

to suggest improvements to the protocols. The reasoning about some protocols has been mechanically verified. This paper starts with an informal account of the problem, goes on to explain the formalism to be used, and gives examples of its application to protocols from the literature, both with shared
