The concept of destroying a malignant cell in situ while leav ing its normal neighbor intact and functioning has many parallels among well-known immunologie phenomena. It is, therefore, not surprising that for well over 50 years an immunologie approach has held a logical attraction for students of cancer. Immunologie studies have, for a large part, concentrated on the antigenic structure of the...

Two distinct credit channels for monetary policy have been described.’ Both of these channels are based on lending problems associated with asymmetric information and control.2 The cost of acquiring information and controlling borrower’s behavior drives a wedge between the cost of internal and external finance. For some borrowers the premium for external finance is so large that it is impractic...

tion. In two very interesting cases which have come under the observation of the present writers, the symptoms were suggestive rather of a B. coli infection of the urinary tract than of a fever of the enteric group. In both cases however it was possible to make a positive diagnosis of B. columbensis infection of the urinary tract, the bacteriological test being confirmed by an agglutination rea...

Nowadays, the tendency to survey and accelerate technological processes in order increase produc-tion efficiency on one hand reduce ecological impact of production environ-ment other is increasingly prevailing. These aspects encourage both applilcation mathematical modelling utilization new material types ensuring suffi-cient strength ductility while reducing overall weight final asembly. This ...

The viscosity of iodine must be of the same order of magnitude as that of bromine and the same holds for solutions in the two solvents. The concentrations at which the minimum conductance appears would seem to indicate a dielectric constant markedly higher than that of bromine at 250. In benzene (D. const. = 2.28), the conductance minimum for a strong salt lies at 1 X 10-1 N; for anisole (D = 4...

Motion smear is an important visual cue for motion perception by the human vision system (HVS). However, in image analysis research, exploiting motion smear has been largely ignored. Rather, motion smear is usually considered as a degradation of images that needs to be removed. In this paper, we establish a computational model that estimates image motion from motion smear information--"motion f...
