  2. 1. Dispersion and risk assessment of airborne contaminants in pharmaceutical clean rooms

    Author : Berit Reinmüller; KTH; []
    Keywords : airborne contamination; clean rooms; clean zones; clothing systems; dispersion of contaminants; LR-Method; microbiological risk assessment; risk assessment; source strenth;

    Abstract : In many of today's industries, particularly in the healthcare field, special protection is required against airbornemicrobiological contamination. Clean rooms and clean zones areused to separate the ambient environment from contaminationcontrolled areas. READ MORE

  4. 2. A new generation of hospital operating room ventilation

    Author : Parastoo Sadeghian; Sasan Sadrizadeh; Catherine Noakes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation systems; bacteria-carrying particles; airflow behaviour; operating room; computational fluid dynamics; surgical site infection; Ventilationssystem; bakteriebärande partiklar; luftflödesbeteende; operationsrum; numerisk strömningsmekanik; kirurgirelaterad infektion; Strömnings- och klimatteori; Fluid and Climate Theory;

    Abstract : Surgical site infection is responsible for 38 percent of reported infections after surgery. This infection increases mortality and treatment costs, and prolongs the hospitalization of patients. READ MORE

    Abstract : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. READ MORE

  6. 4. Unsymmetric PCN Pincer Palladium and Nickel Complexes : Synthesis, Characterization and Reactivity

    Author : Abdelrazek Mousa; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unsymmetric PCN; Palladium; Nickel; Cyclometallation; Carboxylation; Cross-coupling;

    Abstract : New palladium and nickel complexes based on unsymmetric PCN pincer ligands have been synthesized and fully characterized using different techniques. The substituents on the nitrogen side arm of the ligand have great influence on the cyclometallation and the reactivity of the new complexes particularly in case of nickel. READ MORE

  7. 5. Towards Abatement of Selected Emissions from Metals Manufacturing

    Author : Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Abstract : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. READ MORE
