TL;DR: The field ion microscope is the only instrument in existence capable of showing individual atoms on the surface of a solid as mentioned in this paper, and it can also be used to study the threedimensional structure of the material, by removing successive atom layers from the surface by the process of field evaporation.

TL;DR: A mobile pressure chamber has been used to treat patients suffering from severe carbon monoxide poisoning with oxygen at 2 atmospheres pressure for five years, and of the 25 patients treated, 20 recovered completely and only three died.
Abstract: For the past five years a mobile pressure chamber has been used to treat patients suffering from severe carbon monoxide poisoning with oxygen at 2 atmospheres pressure. Of the 25 patients treated, 20 recovered completely and only three died. This apparatus could also be used for hyperbaric oxygen therapy in other conditions for which it is indicated.

TL;DR: In this article, the authors investigated the possibility of obtaining accurate values of arterial Po2 from specimens of capillary blood stored in glass capillary tubes and measured in an oxygen microelectrode.
Abstract: In this study we investigated the possibility of obtaining accurate values of arterial Po2 from specimens of capillary blood stored in glass capillary tubes and measured in an oxygen microelectrode. It has been shown that Po2 measurements made on the Radiometer oxygen microelectrode are as accurate as those made on the macroelectrode and that the storage of blood is as satisfactory in glass capillary tubes as in glass syringes. The important feature in obtaining accurate values for arterial Po2 is the choice of the capillary bed and its method of preparation for sampling. If the ear lobe is massaged with thurfyl nicotinate (Trafuril) it is possible to obtain values of Po2 from the capillary blood which are in close agreement with arterial Po2 in normal, hyperoxic, and shocked vasoconstricted patients.

TL;DR: In this article, the elements of a matrix display are formed of materials whose reflectivity is sensitive to an electric field at the space charge layer of their surfaces, see Division H4, are described.
