    Notizen: . Immunological relationships between genera and species of microsporidia were examined by immunoblot analysis. Exospore polypeptides from two Nosema spp., three Vairimorpha spp., and two undescribed Vairimorpha-like isolates were analyzed. Gel electrophoresis and immunoblot analysis revealed that a variety of polypeptides, mostly between 15,000 and 90,000 molecular weight, are present on the exospore. The three Vairimorpha spp. are closely related immunologically to each other, but less so to the two undescribed Vairimorpha-like isolates. The two Nosema spp. are immunologically distant from each other and from the Vairimorpha spp. Indirect evidence, however, indicated that many internal spore polypeptides present in both genera are similar. Cross-reactivity between exospore polypeptides from entomophilic microsporidia and antisera to a mammalian microsporidium, Encephalitozoon cuniculi, was very limited. These results indicate that immunoblot analysis of exospore polypeptides may be employed to investigate the interrelatedness of microsporidian species, and that exospore polypeptides of some microsporidia are sufficiently diverse to be of immunodiagnostic value.

    Notizen: Abstract. Eulaliopsis binata is a perennial fibre-producing plant, which has a growing market in southern China and also has favourable effects on soil and water conservation. In the present study, three land use treatments, Eulaliopsis binata (EB), undisturbed natural grassland (NG) and orange grove (OG) were compared with respect to their effects upon a red soil after 20 years. Of these treatments, EB had the most favourable effects on soil physicochemical and biological properties and on soil microclimate. These properties were combined in a relative soil quality index (RSQI), which gave values in the order EB 〉 OG 〉 NG. Soil microbial numbers and enzyme activities were shown to be sensitive indicators of overall changes in soil properties.

    Changes in soil quality due to introduction of broad-leaf trees into clear-felled Chinese fir forest in the mid-subtropics of China (2004)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: Abstract. After clear-felling of a first generation Chinese fir (Cunninghamia lanceolata) forest, mixed stands of Chinese fir and Michelia macclurei (a broadleaf tree) (MCM), pure M. macclurei stands (PMS) and pure Chinese fir stands (PCS) were established in 1983. The effects on soil were evaluated 20 years after planting by measuring physicochemical, microbiological and biochemical parameters. Both broadleaf monoculture and mixtures of broadleaf and conifer exerted a favourable effect on soil fertility. A soil quality index (SQI) decreased in the order: PMS (0.62) 〉 MCM (0.57) 〉 PCS (0.41). Improvement in soil quality, enhanced biological activity and forest productivity demonstrated that mixed stands are an effective measure to maintain sustainable forest productivity, as well as to control soil degradation under successive stands of Chinese fir. In addition, since the microbiological and biochemical parameters measured were sensitive to the forest management, they may be potential indicators for assessing the sustainability of different management systems. The results also showed that total organic carbon, cation exchange capacity and microbial biomass carbon are effective indicators of the improvement or deterioration of soil quality under forest.

    The 14C age and residence time of organic matter and its lipid constituents in a stagnohumic gley soil (1996)
    Oxford, UK : Blackwell Publishing Ltd
    European journal of soil science 47 (1996), S. 0

    Notizen: A combination of radiocarbon (14C) dating and biomarker analyses of the aliphatic hydrocarbons in soil lipids is proposed as a novel and improved method for studying the environmental history of peaty soils. The radiocarbon concentration of unfractionated bulk organic matter, hydrolysed soil residues and two lipid fractions (the aliphatic hydrocarbons and carboxylic acids) recovered from a stagnohumic gley soil, were compared using AMS (accelerator mass spectrometry) and radiometric 14C dating techniques. The radiocarbon ages recorded by the aliphatic hydrocarbon fractions were consistently older than those measured from the unfractionated soil, and were in most cases older than the residues remaining after acid hydrolysis. This pattern was observed at three different depths in the soil profile. The apparent age difference between the hydrocarbon fraction and its unfractionated substrate increased with depth. An abundance of long–chain n–alkanes, similar to those found in higher plant waxes, characterized the aliphatic hydrocarbon fraction from the deepest soil (at 21.5–24.5–cm depth). The radiocarbon age of this basal organic component (13470± 170 years bp) indicated that it derived from the initial re–establishment of vegetation on the local deglaciated landscape with the onset of the Windermere Interstadial (c. 14000–13000 14C years bp). Bulk organic detritus within the basal horizon dated at some 3000 years younger, and presumably as a result of the downward penetration and retention of some mobile organic residues produced later in the development of the soil profile. The survival and apparent stratigraphical stability of these recoverable aliphatic hydrocarbons provides the opportunity, via the development of AMS dating, to measure an unambiguous radiocarbon age for the origin of organic residues retained in soils and sediments.

    Thema: Wirtschaftswissenschaften
    Notizen: Since her founding in 1949, China has gone a long way in formulating her own R&D structure and policy. There are successful stories and painful lessons as well. In this paper the author intends to examine the evolution of the Chinese R&D structure and policy; the pros and cons with this structure and policy. And finally how China is at present reforming the structure and policy, and why she is doing so.Structure and policy are two of the key factors that affect the effectiveness of R&D. With appropriate structure and policy, R&D will not only advance the state of art of science and technology, but also contribute a great deal to the progress of the society and the prosperity of the nation's economy. Therefore, the main theme of the paper will be concentrated on how China could reform her R&D structure and policy so that R&D can play a bigger role in building up China's economy and modernization.

    Notizen: : Moisture (49.70 to 74.20% w/w) and salt (0.13 to 12.30% w/w) concentrations in cured Atlantic salmon (Salmo salar) or teijin were determined by short-wavelength near-infrared (SW-NIR) reflectance spectroscopy (600 to 1100 nm) using partial least square regression (PLS) and artificial neural networks (ANN) calibration methods. ANN and PLS yielded similar results (Salt: ANN RMS = 1.43% w/w, PLS RMS = 1.37% w/w; Water, ANN RMS = 2.08% w/w, PLS RMS = 2.04% w/w). Sampling the dorsal or ventral portion of the fish did not appear to affect the prediction error of the salt or moisture models.

    Thema: Architektur, Bauingenieurwesen, Vermessung
    Notizen: Information loss is caused when a surface is sampled with a finite interval, such as in the production of a digital elevation model (DEM). This information loss can become the dominant part of the error in a DEM. The ability to quantify information loss enables guidance to be provided for an appropriate choice of grid interval and better accuracy assessment for the DEM. With the use of digital photogrammetric systems, evaluation of information loss has become much easier. This paper describes three methods of evaluating information loss. An example is given of the method which is most appropriate for use with a digital photogrammetric system, based on rock cliff surface data and the VirtuoZo system.

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Significant thermal effects on in vitro protein quality of red kidney beans were observed. Beans autoclaved at 121°for 10 and 20 min, and common home-cooked beans had improved protein quality. Uncooked beans, and those autoclaved at 128°for 20 min and at 121°for 90 min had reduced protein quality compared to canned beans and those autoclaved at 110°for 20 min and at 121°for 40 and 60 min. Amino acid scores, essential amino acid index and available lysine (%), corrected for in vitro protein digestibility gave comparable results in evaluation of protein quality. Specific lysine, methionine, cysteine and other amino acid ratios overestimated protein quality.

    Notizen: Transversal ultra-structure and firmness were examined on cooked spaghetti-shaped pasta prepared from durum semolina with 0% (control), 10%, 20%, and 30% Alaskan pollock surimi. The ultra-structure of the pasta exhibited two differences between inner and outer gross structures of the extruded product. In the inner portion, control and surimi-added pasta were not different. In the outer portion, surimi gel was observed as a network with small cavities uniformly distributed throughout the matrix formed by the gluten and/or gelatinized starch of durum semolina. Cooked firmness of the pasta decreased with addition of surimi.

    Notizen: : :Tenderization treatments of black abalone (Haliotis cracherodii) were conducted using papain solutions (0.25% or 0.50%) with tumbling (10 or 20 min) prior to canning. The treated adductor and opercular (foot) muscle were evaluated by sensory and instrumental methods and compared to untreated black abalone, to untreated blue abalone (H. fulgens) and to commercially canned blue abalone. Treatment with papain did not significantly alter the texture of the abalone but did increase metallic and bitter character notes, possibly by releasing amino acids on protein degradation. Instrumental texture measurements correlated with sensory texture measurements and may aid in the establishment of quality parameters for canned abalone.
