Experimental diabetes has been characterized as a metabolic state involving both overproduction and underutilization of glucose. Although these changes have been recognized for many years, the specific biochemical alterations resulting in increased hepatic glucose production have not been adequately described. The adrenal cortical steroids are known, however, to have an important role in the re...

1. The size of the dose of the infecting material exerts an appreciable effect upon the duration of the incubation period in experimental syphilis of the rabbit. Other things being equal, the larger the dose the shorter is the incubation period. 2. The size of the inoculum was not found to exercise any marked effect upon the course of the disease as a whole. 3. In individual rabbits inoculated ...

The inefficiency of specific sera in the treatment of pneumonia must be attributed in part at least to the lack of exact knowledge of the nature of the infection and the processes whereby the human organism protects itself. To ascertain detailed facts regarding pneumococcus infection one must resort to laboratory animals, none of which so far as is known reacts to such infections in identically...

In defibrillation, current flow depends on the energy selected and the transthoracic impedance. If transthoracic impedance is high, current flow may be inadequate to defibrillate. We developed a method by which high transthoracic impedance is automatically compensated for by an increase in operator-selected energy when impedance is high. Transthoracic impedance was predicted in advance of the f...

The work of previous investigators gives the impression that it is easy to produce sera which both in vitro and upon injection are leukotoxic. At the same time the specificity of these leukotoxic sera for the particular type of cell used as antigen, and even for leukocytes in general, has been doubtful. The methods used have made certain possible factors of error unavoidable. Even careful washi...

in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...

co2 emissions from combustion flue gases have turned into a major factor in global warming. post-combustion carbon capture (pcc) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas co2. to test a new solvent (ait600) for this purpose, a small pilot plant was used. this paper presents the results of studies on chemical methods of...
