Study of multicharged heavy ion generation from CO2 laser-produced plasma

The results of lead ion generation with charge state from Pb10+ to Pb35+ from laser-heated plasma are presented. CO2 lasers producing 10.6-μm wavelength radiation at power densities in the range 4.1011-6.1014 W/cm2 in TBKI and CERN were used. Results of detailed numerical simulations presented in the paper are in good agreement with the experimental data. Work done in collaboration with CERN, ITEP, and TBKI was aimed at the specification of requirements for a laser system that will be able to drive an ion source for the hadron collider (LHC) at CER

CLINICAL EFFECTIVENESS OF OSMOTIC LAXATIVE DRUGS IN EARLY POSTOPERATIVE PERIOD IN CHILDREN WITH CHRONIC COLON STASIS

The clinical effectiveness of osmotic laxative drugs based on lactulose in restoration of gastrointestinal tract function in early postoperative period after transanal interventions and laparoscopic operations in 53 children 2–17 years old was studied. All patients had non-functional (cologenic and proctogenic) constipation. Patients underwent full-thickness laparoscopic or transanal biopsy due to suspicion of gastrointestinal malformation presence. Children from base group (n = 28) used lactulose (Duphalac) from the second day of postoperative period (dose complied with the age) once daily, in the morning. The control group (n = 25) received subcutaneous or intramuscular proserinum for the stimulation of peristalsis. Blood tests with serum potassium control were performed on 2nd and 4th day. The study showed clinical effectiveness of lactulose in treatment of postoperational hypotonic constipation in children with colon malformations. Key words: children, gastrointestinal malformations, postoperative period, chronic constipation, lactulose.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2010;9(1):122-125
