Using sie®e-tray air stripping as a means of remo®ing contaminants from surfactant solutions was studied to determine if tray air stripping can be applied successfully to treating surfactant-containing wastewaters and, if so, to de®elop a quantitati®e approach for designing tray air-stripping systems for treating surfactant-containing wastewaters. High-concentration surfactant solutions were pr...

Ecosystem disturbances that remove vegetation and disturb surface soils are major causes of excessive soil erosion and can result in accelerated transport of soils contaminated with hazardous materials. Accelerated wind erosion in disturbed lands that are contaminated is of particular concern because of potential increased inhalation exposure, yet measurements regarding these relationships are ...

background: to determine the efficacy of different antiseptic solutions (control group (i), antibiotic solution (ii), chlorhexidine 0.4% (iii), and povidone – iodine 10% (iv)) in sterilizing contaminated osteochondral plugs. methods: under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. a total of 200 osteochondral specimens ...

result from other techniques, such as those requiring aeration of cultures. The exhaust air from such operationls must be sterilized and the most reliable means of doing this is incineration. The 1 cfm capacity of the incinerator described above is sufficient for mnost laboratory scale operations. If provision is made for cooling the exit air, the apparatus may be employed as a source of steril...

Measurements of radionuclides (RNs) in air made worldwide following the Fukushima accident are quantitatively compared with air and soil measurements made in Japan. Isotopic ratios RN:(137)Cs of (131)I, (132)Te, (134,136)Cs, are correlated with distance from release. It is shown, for the first time, that both within Japan and globally, ratios RN:(137)Cs in air were relatively constant for prima...

Posttraumatic diaphragmatic hernia is a rare cause of large bowel obstruction, and can present weeks or years after the initial trauma. Herein, we report the case of a 28-year-old man who presented with signs and symptoms of bowel obstruction nine months after he had a stab wound to his left chest. Chest radiography showed multiple air‑fluid levels in the right upper quadrant, an air-fluid leve...

Results B. cereus complex constituted 164 cases (71.3%). Bacteraemia comprised 207 patient episodes (90.0%), of which 124 occurred in immunocompromised patients or those with intravascular devices. Physicians treated the organism in 68 episodes (29.5%). Environmental investigations confirmed heavy air contamination particularly within patient rooms and air conditioned wards. Dense airborne cont...
