For over a decade, dCache has been synonymous with large-capacity, fault-tolerant storage using commodity hardware that supports seamless data migration to and from tape. In this paper we provide some recent news of changes within dCache and the community surrounding it. We describe the flexible nature of dCache that allows both externally developed enhancements to dCache facilities and the adoption of new technologies. Finally, we present information about avenues the dCache team is exploring for possible future improvements in dCache.
on " Unexplained Steatorrhoea in the Syndrome of Hyponatraemia and Carcinoma of Bronchus" (February 3, p. 287). They conclude that inappropriate secretion of antidiuretic hormone was the most likely cause of the hyponatraemia and renal salt wasting in their patient. This seems a reasonable supposition in the light of other published cases. However, no statement is made in the report that the urine was consistently hypertonic to plasma, in the face of plasma hypotonicity. In fact, it is stated that the patient could dilute normally to a specific gravity of 1002. This would seem inconsistent with the thesis that there was increased antidiuretic hormone activity unless, at the time of the test, renal tubular responsiveness to A.D.H. had decreased, perhaps through potassium depletion. The high ammonium output in relation to pH after ammonium chloride loading possibly reflects the urinary tract infection present in this patient; a defect in acidification of tubular origin is unproven. This finding would be equally consistent with an acquired defect due to potassium depletion. The negative response to nicotine stimulation, and the impaired ability to concentrate urine after pitressin, could be explained on a similar basis. The results of these tests suggest either that inappropriate A.D.H. secretion was a transient phenomenon, not operating throughout the patient's illness, or an acquired renal resistance to A.D.H. had developed, perhaps due to potassium depletion, a likely consequence of steatorrhoea. Pyelonephritis would be a less likely alternative explanation.-I am, etc.,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
