Thermoacoustic Metasurfaces In article number 2202026, Ying Cheng, Xiaojun Liu, Johan Christensen, and co-workers report an orbital-angular-momentum multiplexing technology based on space-time thermoacoustic metasurfaces for enhanced communication densities. analogy to the Chinese story “Monkey King Prays Rain”, multifaceted weather signals, i.e, lightning, thunder rain, etc., are synchronously...
BACKGROUND ILCOR recommend the use of therapeutic hypothermia (32-34 degrees C) for 12-24 h in unconscious adult patients with spontaneous circulation after cardiac arrest with a VF rhythm. Among various methods of inducing hypothermia, the rapid infusion of ice-cold intravenous fluid has been used. METHODS To investigate the time required to cool intravenous fluids in a domestic refrigerator...
Computerized tomography has had a huge impact on medical diagnostics. Numerous methods of tomographic medical imaging have been developed and are being developed (e.g., the ‘standard’ X-ray, single-photon emission, positron emission, ultrasound, magnetic resonance, electrical impedance, optical) [62, 67, 84–86]. The designers of these modalities strive to increase the image resolution and contr...
More than one year has passed since refrigerant for refrigerator was changed from CFC12 to HFC134a. Long term reliability of refrigerator in HFC134a refrigerant system is mainly dependent on lubrication of moving parts of compressor and clogging of capillary tube. To maintain better practical reliability in components in compressor such as refrigeration lubricant,metallic materials and motor in...
Refrigerator ownership in rural China increased from 14% to 45% over the period 2001-2010.We test the impact on demand for food, particularly meat, using fixed-effect and demand system approaches based on provincial data. Results suggest that rising refrigerator ownership had a negative effect on rural at-home meat demand.
-Lymph-node cells of (AKR x C3H) F1 leukaemic mice showed a considerable increase of glycolytic activity and 02 consumption. The glycolytic enzymes phosphofructokinase, pyruvate kinase, aldolase and lactic acid dehydrogenase showed increased activities in leukaemic conditions. Studies on permeabilized leukaemic and normal lymph-node cells, and assays on partially purified phosphofructokinase an...
