    Notizen: Fungi exist in every indoor and outdoor environment. Many fungi are toxigenic or pathogens that may cause various public health concerns. Rapid and accurate detection and identification of fungi require specific markers. In this study, partial mitochondrial large subunit rDNA was amplified and sequenced from 32 fungal strains representing 31 species from 14 genera. Based on the sequence variation pattern, 26 oligonucleotide probes were designed for their discrimination. The specificity of the probes was evaluated through homology search against GenBank database and hybridization examination on 38 fungal strains. The 26 probes were verified as highly specific to 20 fungal species. A two-step detection procedure through PCR followed by probe hybridization gave ten-fold increase in detection sensitivity than single-step PCR assay and would be a practical approach for environmental sample screening. The probes developed in this study can be applied in clinical diagnosis and environmental monitoring of fungal agents.

    Quality Changes of Shrimp (Pandalus borealis) Stored under Different Cooling Conditions (2005)

    Notizen: The influence of different cooling techniques and storage temperatures (-1.5 °C or 1.5 °C) to prolong the shelf life of shrimp was evaluated by sensory analysis, physical methods, chemical analysis, and microbial analysis. Storage in liquid ice was more effective than flake ice or brine mixed with flake ice in delaying spoilage of the shrimp by slowing down microbial growth and formation of total volatile basic nitrogen (TVB-N) and trimethylamine (TMA). Total viable counts (TVC) showed that bacteria grew most quickly in shrimp stored in flake ice and in brine mixed with flake ice, followed by those in liquid ice at 1.5 °C and -1.5 °C, respectively. Lowest counts were observed in shrimp stored in liquid ice at -1.5 °C where the lag phase of growth was apparently extended at the beginning of storage. Principal component analysis (PCA) showed a good correlation between quality indicators related to microbial growth, TVC, pH, TVB-N, TMA, responses of an electronic nose and sensory evaluation.

    Shear Capacity of Reinforced Concrete Beams under Biaxial Bending Based on Equivalent Cross-Section Method (2008)
    s.l. ; Stafa-Zurich, Switzerland
    Key engineering materials Vol. 400-402 (Oct. 2008), p. 275-280 
    Details

    Thema: Maschinenbau
    Notizen: Based on the analysis of reinforced concrete beams under biaxial bending, an equivalent cross-section method is proposed to calculate the shear capacity of the beams. According to the two basic equivalence principles, a biaxial flexural beam is changed into a uniaxial flexural member, and the shear strength of biaxial flexural beam is calculated as a uniaxial flexural member. Furthermore, the interrelationships among the equivalent cross-section and the neutral axis inclination as well as the ratio of depth to width of the cross-section are deduced in advance. The ratios of some typical cross-section’s equivalent dimensions to its original ones are pointed also. In order to verify the availability of the equivalent cross-section method, some academic references about the ultimate strength of biaxial flexural beams are consulted in this paper, and the shear capacity computing methods by literatures for uniaxial flexural beams are adopted in the strength calculation of biaxial flexural reinforced concrete simply supported beams with stirrups or without stirrups. The comparison between the calculation results and experimental results shows that the presented equivalent cross-section method is feasible and practical which can be used as a reference in practice design

    Notizen: This paper aims to study the uncertainty of the MDOF structural dynamic response, takingnot only the interval characteristics of structural physical parameters and geometric dimension, butalso the interval characteristics of applied load simultaneously . By means of the description of theinterval parameters of uncertain structure with affine forms, the interval structural dynamic equationis studied, and an improved affine arithmetic based on interval division is presented, wherecorrelations between the interval elements in eigenvalue and responses equations are considered,independent uncertain parameters are transformed to affine forms, and the solution of eigenvalue andresponse equations are transformed into the corresponding certain ones. With general affinearithmetic, the eigenvalue of each order and response bounds are determined by searching for themaximum and minimum in the solutions. Finally, some mathematical examples and a furtherengineering application confirm the feasibility and validity of this approach

    Notizen: Natural clay minerals are ideal nanofillers for polymer materials and have been attractedtremendous research and development interests in the past decade. The manufacture of claynanofillers relies largely on the exfoliation of clay particle into individual clay platelets. Thus,understanding the interlayer swelling of clay minerals upon the adsorption of surfactants is importantto the fabrication and design of polymer nanocomposites. This paper reports our recent experimentaland theoretical studies on a variety of organoclays that show a linear relationship between the increaseof d-spacing and the mass ratio between organic and clay

    Notizen: Polymer nanocomposites are recognized as the next generation of polymer compositesdue to their exceptional properties. Understanding the molecular origin of the reinforcementmechanism is crucial to the development of such promising materials. This paper reports our recentmolecular dynamic study on clay-based polyurethane nanocomposites. The effect of clay plateletson phase separation behavior of polyurethane, at the clay-polyurethane interface, is quantified interms of molecular interactions, structure and dynamics. The results show that the nanoconfinementof polyurethane chains in clay gallery impedes the development of phase separationcommonly observed in bulk polyurethane. The absence of phase separation of intercalatedpolyurethane is believed to be related to the competitive interactions among clay platelet,polyurethane and surfactant

    Notizen: N-carboxyethyl chitosan (ACS) was formed by a Micheal reaction. Through the analysisof IR and 1H-NMR spectra, the Micheal reaction was carried out between - NH2 of chitosan and - C= C - of acrylic acid. ACS hydrogel (ACSG) was prepared by cross-linking with glutaraldehyde.ACSG show pH-sensitive swelling behavior, and the smallest swelling rate (SR) of ACSG is in pH5.0buffer solution.With dosage of glutaraldehyde increasing, the SR of ACSG decreased. With graftingdegree (GD) increasing, the SR of ACSG increased first and decreased afterward. Using bovineserum albumin (BSA) as a model medicine, the releasing behaviors of ACSG were investigated invitro. In simulated gastric and intestinal fluid, the ACSG loading BSA (GD=20.45%) has betterreleasing behaviors

    Notizen: Abstract: The case of a 21-year-old woman presenting with macronodular multi-organs tuberculoma is reported. She was examined for pulmonary tuberculosis on a chest X-ray film in January, 1995, and admitted with a cough, anorexia, and abdominal pain in July, 1996. Computed tomography revealed multiple calcified nodules with peripheral hypodense areas in the brain, and calcified hypodense masses in the liver and spleen. Magnetic resonance (MR) imaging showed hypointense masses in the liver and spleen on T1-weighted spin echo images and a hypointense mass with a hyperintense area on T2-weighted spin echo images. On contrast-enhanced dynamic MR images, the liver and spleen masses were unenhanced and hypointense with slight rim enhancement. T2-weighted spin echo images showed a round hypointense nodule in the right kidney and hydronephrosis and enlargement in the left kidney. Antituber-culous treatment was started with a gradual improvement in her signs and symptoms. Her temperature became normal. However, she was systemically treated with antituberculous chemotherapy 10 months later, her condition worsened again. She died from increased intracranial pressure in August, 1997.
