Indicator organism sources and coastal water quality: a catchment study on the island of Jersey.

Compliance monitoring of bathing waters at La Grève de Lecq on the North coast of Jersey revealed a significant deterioration in water quality between 1992 and 1993, as indexed by presumptive coliform, presumptive Escherichia coli and streptococci concentrations. During the 1993 bathing season the beach failed to attain the compliance with the EC Guideline criteria for presumptive E. coli and streptococci. A bacteriological survey of the stream catchment draining to the beach revealed that: (i) concentrations of faecal indicator organisms were enhanced at high discharge after rainfall; and (ii) a captive water fowl population, which expanded between 1990 and 1993, was a potential source of faecal pollution. Strategies for catchment management are discussed.

Legacy systems: managing evolution through integration in a distributed and object-oriented computing environment.

Legacy systems are crucial for organizations since they support key functionalities. But they become obsolete with aging and the apparition of new techniques. Managing their evolution is a key issue in software engineering. This paper presents a strategy that has been developed at Broussais University Hospital in Paris to make a legacy system devoted to the management of health care units evolve towards a new up-to-date software. A two-phase evolution pathway is described. The first phase consists in separating the interface from the data storage and application control and in using a communication channel between the individualized components. The second phase proposes to use an object-oriented DBMS in place of the homegrown system. An application example for the management of hypertensive patients is described.

[Thermal isolation of the heart by means of a plastic foam pad during surgical cooling of the heart: experimental study].

Maintenance of myocardial cooling during aortic clamping is a problem encountered currently during heart surgery. A plastic foam isolation pad was studied. Eight animals (pigs weighing 50 kg) were placed on extracorporeal circulation, 4 of them constituting the control group (A). Two coronary injections of a cardioplegic solutions were administered, the first at the time of aortic clamping and the second 30 minutes later. The myocardium of the 4 animals in the treated group (B) was isolated with the foam pad, and this significantly prolonged the "cold" effect of the cardioplegic. Ten minutes after injection of the cardioplegic, temperature of the total myocardial mass with isolation was between 10.7 and 12 degrees C, as against 16 to 18 degrees C in the reference group (p less than 0.05). By the 20th minute, the isolated myocardium was at approximately 15 degrees C as against 22 degrees C in group A (p less than 0.01). Finally, by the 30th minute, temperature in group B was 17 degrees C as against 23 degrees C in group A (p less than 0.01). Reheating of the heart was significantly slowed by thermal isolation, though the limit of 15 degrees C was reached by the 20th minute. To ensure that myocardial temperature remains below this limit when the foam pad is employed, further injections of cardioplegic solutions are necessary every 20 minutes.
