    Notes: Seventy-one patients scheduled to undergo upper or lower abdominal surgical procedures were allocated at random to one of seven treatment groups: in the recovery room they were to receive oxygen via a 40% Ventimask with 10 litres/minute oxygen flow, or via either a Hudson mask or a nasal cannula with 3,6 or 9 litres/minute oxygen flow. The 40% Ventimask gave the most consistent, satisfactory postoperative values of PaO2 but the much cheaper nasal cannula at 6 or 9 litres/minute was generally adequate in conscious patients. The performance of the intermediately priced Hudson mask was similar to that of the nasal cannula at these flows. The unconscious state was associated with a 45% lower PaO2 than the rousable or awake states. Differences between the treatments with regard to postoperative PaCO2 were small and non-significant. The nasal cannula with 6 litres, minute humidified oxygen flow is recommended for routine treatment, and the Ventimask for unconscious patients.

    Notes: A case is described where a patient received less oxygen than was set on the Rotameters. The cause was traced to a selective leak of oxygen via an open cyclopropane needle valve. Several recommendations are put forward to prevent a recurrence.

    Notes: We argue that the widely held view that the transition-metal monoxides are Mott insulators is incorrect. Self-consistent spin-polarized energy-band calculations indicate that MnO and NiO are ordinary band insulators, and that FeO and CoO, while conducting in the local-spin-density approximation, satisfy the condition required for insulating behavior due to the development of an orbital magnetic moment. Our picture of the monoxides is supported by a variety of experimental data. The fundamental question raised by this work is the importance of charge fluctuations, or equivalently, of ionic configurations. The distinction between our band picture and the conventional picture based on ionic configurations (the energy price for which is the Coulomb integral "U'') is particularly clear for the variation of the Néel temperature across the monoxide series. Perturbation theory indicates that T(Néel) varies inversely with U in the conventional theory, but inversely with the exchange splitting in the band picture. Since the exchange splitting tends linearly toward zero across the series, whereas U is constant or increases, the increase by a factor of five of T(Néel) across the series is more naturally explained by the band picture.

    Notes: A measurement of the effect of mildew and leaf blotch on both yield and quality of Lolium multiflorum (cv. Lior) was undertaken in two trials sown in 1966 and 1967.Plots were sprayed with a fungicide at 10-day intervals, and four cuts were taken during the season. Disease assessments were made at the time of cutting. Considerable differences in yield and quality were recorded which could be broadly related to the levels of disease infection in the treatments.

    Notes: Abstract Ultrasonic instruments used in dentistry generally operate at frequencies of 25 to 42 kHz. A wire oscillating at these ultrasonic frequencies immersed in a liquid produces local flow patterns termed acoustic microstreaming. Large shear forces are produced which arc able to rupture erythrocytes and platelets both in vitro and in vivo. This results in activation of the blood coagulation system with subsequent thrombus formation. The probe tip of an ultrasonic sealer was positioned to touch a mammalian mesenteric artery. The probe was operated for 10 to 20 s at a displacement amplitude of 15 μm. Acoustic microstreaming occurred which disturbed blood flow and this microstreaming ceased when the power was switched off. After continued operation of the probe, thrombi were formed against the vessel wall with fragments embolising downstream. These thrombi eventually grew to occlude the vessel. Furthermore, an in situ model demonstrated that acoustic energy was transmitted through the tooth during typical ultrasonic scaling procedures. As a consequence of these observations, it is possible that acoustic microstreaming fields may be generated within the blood vessels entering the tooth apex which arc large enough to induce platelet damage. Therefore there is a potential hazard from the use of the ultrasonic sealer which may induce similar thrombi formation within the pulpal or perapical tissues of the teeth. If this were to occur it could result in tooth death which might not become evident until a long time after the ultrasonic exposure.

    Notes: Twelve beef/pork meat blends were made from lean of mature beef and dark or mature pork carcasses. Meat blends containing about 20% beef fat were rated higher for appearance scores by a consumer panel than blends made with 20% pork fat. Visual acceptance of beef/pork patties was accomplished via use of all-beef fat and additionally by extending mature beef (MB) with mature pork (MP) or dark pork lean (DP). Agtron calorimetry scores indicate a minimum of 20% MB lean extended with 60% MP was needed to create the appropriate red color attractive to consumers. Use of 60% MP lean with about 20% beef fat resulted in patties acceptable to consumers for visual appearance and eating satisfaction.
