Preoperatiewe spesiale ondersoeke en intraoperatiewe arteriele suurstofspanning tydens eenlongnarkose
The value of preoperative lung function tests was examined in 11 patients as a method to predict changes in intraoperative Pa02 (dPa02) during one-lung ventilation in pulmonary surgery. Ventilation (Kr-81m and Xe-133) and perfusion (Tc-99m microspheres) to the lung to be operated upon significantly predicted the intra-operative decrease in Pa02. The correlation between ventilation percentage to the diseased lung and dPa02 was 0,87 (SEE = 9,99) and between perlusion and dPa020,84 (SEE = 9,51).S Afr Med J 1990; 78: 104-10
Random-phase approximation and its applications in computational chemistry and materials science
The random-phase approximation (RPA) as an approach for computing the
electronic correlation energy is reviewed. After a brief account of its basic
concept and historical development, the paper is devoted to the theoretical
formulations of RPA, and its applications to realistic systems. With several
illustrating applications, we discuss the implications of RPA for computational
chemistry and materials science. The computational cost of RPA is also
addressed which is critical for its widespread use in future applications. In
addition, current correction schemes going beyond RPA and directions of further
development will be discussed.Comment: 25 pages, 11 figures, published online in J. Mater. Sci. (2012
