Quite recently MacCallum and others 1 have studied calcium metabolism in dogs suffering from post-operative tetany in consequence of parathyroidectomy. The administration either of soluble calcium salts or of parathyroid tissue relieves the tetany in such dogs. This work led us to study a case of infantile tetany which was available. The clinical aspects of the case have been reported elsewhere...
A quantum gas of ultracold polar molecules, with long-range and anisotropic interactions, not only would enable explorations of a large class of many-body physics phenomena but also could be used for quantum information processing. We report on the creation of an ultracold dense gas of potassium-rubidium (40K87Rb) polar molecules. Using a single step of STIRAP (stimulated Raman adiabatic passag...
Using topography collected over one martian year from the Mars Orbiter Laser Altimeter on the Mars Global Surveyor (MGS) spacecraft, we have measured temporal changes in the elevation of the martian surface that correlate with the seasonal cycle of carbon dioxide exchange between the surface and atmosphere. The greatest elevation change (1.5 to 2 meters) occurs at high latitudes ( above 80 degr...
This document provides a description of the small and medium range gas flow calibration facilities at the National Institute of Standards and Technology (NIST) Fluid Flow Group, as reported in NIST Special Publication 250 [1] for Test Nos. 18010C-18040C and 18050S, Flow Rate Measurements. The Fluid Flow Group can perform gas meter calibrations and special tests at flows between 3.7 x 10"^ mVmin...
Objectives • Develop and demonstrate a low-cost, high-pressure water electrolyzer system for hydrogen production – Eliminate need for mechanical hydrogen compressor – Increase electrolyzer hydrogen discharge pressure to 5,000 psig – Reduce capital costs to meet DOE targets – Demonstrate a 3,300 standard cubic foot per day (scfd) high-pressure electrolyzer operating on a renewable energy source ...
BACKGROUND CCR5 is the major coreceptor for human immunodeficiency virus (HIV). We investigated whether site-specific modification of the gene ("gene editing")--in this case, the infusion of autologous CD4 T cells in which the CCR5 gene was rendered permanently dysfunctional by a zinc-finger nuclease (ZFN)--is safe. METHODS We enrolled 12 patients in an open-label, nonrandomized, uncontrolled...
Oceanic transports of heat, salt, fresh water, dissolved CO2, and other tracers regulate global climate change and the distribution of natural marine resources. The time-mean ocean circulation transports fluid as a conveyor belt, but fluid parcels can also be trapped and transported discretely by migrating mesoscale eddies. By combining available satellite altimetry and Argo profiling float dat...
more complete. We may say that we have been working for some time on the side of the subject indicated by the above title with several drugs and hope to be able to submit our more" general results at a later date. With regard to our present observations they were made on the following case of human malaria. A Mahommedan male, aged 23, suffering from malignant tertian malaria was on December 12t...
Rivers provide critical water supply for many human societies and ecosystems, yet global knowledge of their flow rates is poor. We show that useful estimates of absolute river discharge (in cubic meters per second) may be derived solely from satellite images, with no ground-based or a priori information whatsoever. The approach works owing to discovery of a characteristic scaling law uniquely f...
OBJECTIVES The aim of this study was to examine the impact of transient ischaemic attack (TIA) service modification in two hospitals on costs and clinical outcomes. DESIGN Discrete event simulation model using data from routine electronic health records from 2011. PARTICIPANTS Patients with suspected TIA were followed from symptom onset to presentation, referral to specialist clinics, treat...
