A planar waveguide composed of the new nonlinear material, Ca(4)GdO(BO(3))(3) (GdCOB), is reported. This crystal belongs to the calcium oxoborate family. It has attractive nonlinear properties that can be of great interest in integrated optics applications.

A planar waveguide was formed by 2-MeV-helium implantation. We cut the sample to achieve type I noncritical phase matching of an 823-nm fundamental wave for fundamental light propagating along the y axis and polarized along the z crystallophysic axis of the crystal.

Infect Control Hosp Epidemiol
September 2006
Objective: To investigate the potential role of blood pressure (BP) cuffs in the spread of bacterial infections in hospitals.
Design: A comprehensive, prospective study quantitatively and qualitatively evaluating the bacterial contamination on BP cuffs of 203 sphygmomanometers in use in 18 hospital units from January through March 2003.
Setting: A university hospital with surgical, medical, and pediatric units.
Article Synopsis
- The first documented case of endocarditis caused by Bartonella alsatica is reported in a man, highlighting a new risk associated with this bacterium.
- B. alsatica was diagnosed through serological tests, culturing, and PCR analysis of an affected aortic valve.
- This case suggests that B. alsatica should be recognized as a potential zoonotic agent linked to blood culture-negative endocarditis.
