Small bowel perforation from blunt abdominal trauma is a common injury. Isolated perforation of the small bowel after blunt abdominal trauma is infrequent and the diagnosis can be elusive. A case of isolated perforation from blunt trauma is presented. Deterioration of the clinical picture raised suspicion of acute abdomen, perforated sore. If acute abdomen(More)
A genetically marked, plasmid-containing, naphthalene-degrading strain, Pseudomonas putida KT2442(pNF142::TnMod-OTc), has been constructed. The presence of the gfp gene (which codes for green fluorescent protein) and the kanamycin and rifampicin resistance genes in the chromosome of this strain allows the strain's fate in model soil systems to be monitored,(More)
We present a detailed report of the method, setup, analysis, and results of a precision measurement of the positive muon lifetime. The experiment was conducted at the Paul Scherrer Institute using a time-structured, nearly 100% polarized surface muon beam and a segmented, fast-timing plastic scintillator array. The measurement employed two target(More)
Analysis of oil sludge by direct plating and enrichment cultivation revealed 16 strains degrading aromatic compounds. After 30 days of cultivation in a continuous-flow microbial reactor, 17 more degrader strains were isolated. Genotyping of these strains showed that they were taxonomically diverse, and the range of strains degrading naphthalene, benzene,(More)
We report a measurement of the positive muon lifetime to a precision of 1.0 ppm; it is the most precise particle lifetime ever measured. The experiment used a time-structured, low-energy muon beam and a segmented plastic scintillator array to record more than 2×10(12) decays. Two different stopping target configurations were employed in independent(More)
A facultative methylotrophic bacterium, strain Lp-1, which was isolated from root nodules of lupine (Lupinus polyphyllus L.) on the medium with methanol as a carbon and energy source, exhibited high similarity of the 16S rRNA gene sequences to Delftia strains (94‒99.9%). The cells of Delftia sp. Lp-1 were motile gram-negative rods dividing by binary(More)
The ability of 96 microbial strains degrading oil and 32 strains degrading polycyclic aromatic hydrocarbons (PAHs) to consume diesel fuel and oil at 4-6 degrees C and 24 degrees C and at elevated NaCl concentrations was studied. The temperature range, salt tolerance, ability to produce bioemulsifiers, range of substrates, and antibiotic resistance were(More)
The number of spores formed in a single cell of Anaerobacter polyendosporus PS-1T is significantly influenced by the composition of nutrient media. Depending on carbohydrate concentration in synthetic medium, the number of spores may vary from one or two to as many as five to seven. Investigation of spore formation process by fluorescence and electron(More)
The mean life of the positive muon has been measured to a precision of 11 ppm using a low-energy, pulsed muon beam stopped in a ferromagnetic target, which was surrounded by a scintillator detector array. The result, tau(micro)=2.197 013(24) micros, is in excellent agreement with the previous world average. The new world average tau(micro)=2.197 019(21)(More)
