ABSTRACT
We present a magnetic trap for cold atoms near a surface of a millimeter-sized atom chip. The trap allows us to capture a large number of atoms with modest electrical currents (40 A) and to generate large magnetic gradients (>300 G cm-1). Here we report a mixture containing 6 × 109 atoms for the two rubidium isotopes 87Rb and 85Rb. This device does not require cleanroom facilities nor micro-machining technologies which makes its construction easier. In addition our design allows the implementation of an optical dipole trap with a laser beam passing through the chip.
ABSTRACT
OBJECTIVES: The authors had for aim to show that preventing the diffusion of multidrug-resistant organism (MRO) is possible thanks to the coordination of recommended preventive actions and the implementation of a sensible anti-infective prescription policy. They also wanted to highlight the role played by the nursing care staff in enforcing recommendations. METHOD: We compared the results of two health care facilities having both implemented the same strategy aimed at preventing cross-transmission and prescribing anti-infective drugs. RESULTS: Audits reported a very variable enforcement of recommendations. The results obtained from microbiological monitoring confirmed the essential impact of protocol enactment by every team, on the control of MRO diffusion. The antibiotherapy specialist has a key role in the suggested strategy, allowing a significant decrease in the number of anti-infective prescriptions and a more rational use. CONCLUSION: The collaboration of a hygiene specialist with an antibiotherapy specialist has proved operational in the fight against MRO diffusion, as long as the competences of both specialists are acknowledged and their cross-disciplinary activities accepted. For the entire staff, enacting a corporate culture is a crucial asset.

PIP: A review of some recent projections and forecasts of future population growth in Sub-Saharan Africa is presented. Consideration is also given to the problems associated with such projections, including urbanization, education, and employment. The author concludes that policies of population control are inappropriate in the current context.^ieng

The influence of the extraction and fixing of dental amalgams on the metallic concentrations of different biological samples was studied by atomic absorption spectrometry on a subject. The levels of mercury obviously increased in urine, saliva and slightly in blood, with a maximum on the second or third day after the intervention; on the other hand, in the hair, the increase was very low even at the end of 40 days. The urinary and salivary kinetics of silver were practically similar to the ones of mercury. The determination of silver in these fluids could reveal with more specificity the part of dental amalgams on the increase of the metallic biological concentrations. A study with 25 other subjects carrying amalgams permitted to put in evidence some factors facilitating a slight increase of the mercury contents of the saliva, urine and blood.
