Sophisticated packaging solutions can be used in order to preserve vegetables during storage and transport. Polymeric films with selective barriers matching the respiration of the produce, thereby creating an ideal atmosphere inside the package, are available on the market. Fresh broccoli (Brassica oleracea L. var. italica ‘Monterey’) heads were packed in 4 different commercially available polymer

Mollisianitrile (1), a new antibiotic was isolated from the fermentation broth of Mollisa sp. A59-96 together with the two known isocoumarins 2 and 3. 1 exhibited antimicrobial, cytotoxic, and phytotoxic activities. 1 contains a reactive propiolonitrile moiety which is believed to be responsible for its antibiotic activities. Upon incubation with L-cysteine the biological activity was lost.

The fluorescence anisotropic decay is modeled for the B850 bacteriochlorophyll a complex of the purple bacterium Rhodopseudomonas acidophila. Structural information is combined with experimental data to derive a Hamilton operator which models the S-0-S-1 excitation energy transfer between the pigments as well as the energy dissipation into the protein environment. The time-resolved fluorescence si

Various quantities such as plate height (HETP), number of plates (N), axial dispersion coefficient (D-ax) and Bodenstein number (Bo) are used to describe the efficiency of, and dispersion in chromatographic columns. Different quantities highlight different aspects of the performance. Due to the expansion of expanded-bed columns, the information contained in some of these quantities is not the same

Developing guidelines for quality assurance in the management of head injury requires knowledge concerning present management practice. We studied management of minor head injury (MHI) using a cross-sectional mail survey of 76 Swedish hospitals. In 96% of the hospitals, initial patient evaluation, frequently performed by inexperienced physicians, entails neurological assessment according to the Sw

The European shore crab Carcinus maenas is considered to rely on a female pheromone when mating. Evidence, however, is scarce on how the urine pheromone in itself affects males. We investigated male primer and releaser responses to female pheromones with methods that minimized effects from females, delivering female urine either as a pump-generated plume or deposited on a polyurethane sponge. We d

This report describes a language and an interactive environment, called LICS, for implementation of control systems and dynamic modelling. It used graphics for representation of the structural properties: hierarchical decomposition, interconnection structure, and structure of the interfaces. The decomposition and interconnection structures are described by block diagrams. Low level modules are des

This paper examines the coordination of lip and tongue movements in sequences of vowel-bilabial consonant-vowel where the duration of the oral closure for the consonant is varied for linguistic purposes. Native speakers of Japanese served as subjects. The linguistic material consisted of Japanese word pairs that only differed in the duration of the labial consonant, which was either long or short.

Objectives. The receptor for advanced glycation end products (RAGE) is expressed by many cells in joints of rheumatoid arthritis (RA) patients and interacts with a variety of pro-inflammatory ligands that are enriched in inflamed joint. The RAGE-ligand interaction leads to a sustained inflammatory response. Also, secreted form of the receptor, called soluble RAGE (sRAGE), the levels of which are d

BACKGROUND: Information on cancer prevalence is of major importance for health planning and resource allocation. However, systematic information on cancer prevalence is largely unavailable. MATERIALS AND METHODS: Thirty-eight population-based cancer registries from 17 European countries, participating in EUROPREVAL, provided data on almost 3 million cancer patients diagnosed from 1970 to 1992. Sta

The complete mitochondrial genome of the endangered Banded Hare wallaby (Lagostrophus fasciatus) was sequenced and used for phylogenetic analysis. The data set consisted of 10 377 nucleotides (3459 amino acids) from three kangaroo species. The phylogenetic analyses strongly supported the hypothesis that the Banded Hare wallaby is the sister-group of the wallaroo (subfamily Macropodidae). In additi

Popular Abstract in Swedish Akut mellanöreinflammation (akut otitis media, AOM) är en av barnaålderns vanligaste sjukdomare och en av dem som oftast föranleder antibiotikabehandling. De flesta barn får bara någon enstaka AOM, men cirka 5% av dem som insjuknar drabbas sedan av upprepade infektioner (s.k. otit-benägna barn) och blir till ett problem både för patienten, dennes familj och samhället. DAcute otitis media (AOM) is one of the most common childhood diseases and the most common causes of antibiotic treatment in small children. Most children will experience one or two episodes of AOM during preschool age but some will suffer from repeated attacks, they will become otitis-prone. Complications with severe, sometimes fatal infections such as acute mastoiditis and meningitis are nowadays

An understanding of the distribution of water in wood pulp during drying is of fundamental importance to the paper industry. In this study nuclear magnetic resonance (NMR) imaging is used to measure quantitative water profiles during the drying of liquid packaging board with initial water ratio (water: dry mass) of approximately 1.5. The drying was carried out in situ within the magnet, under a ra

Objectives Workers in the rubber industry are exposed to a complex mixture of hazardous substances and have increased risk of developing several diseases. However, there is no up to date survey examining the exposure in the Swedish rubber industry. One of the toxic compounds in the industry is carbon disulfide (CS2), which is biotransformed to 2-thiothiazolidine- 4carboxylic acid (TTCA). TTCA is u
