  • Polysaccharide fractions isolated from Lentinula edodes fruitbodies and mycelium demonstrate strong immunomodulating, antioxidant and anticancer activity. We hypothesized, that polysaccharide fractions enriched in selenium would possess higher biological activity than non-enriched fractions, currently used to treat cancer. The first goal of this study was to isolate selenium (Se)-enriched polysaccharide fractions of different molecular weight from L. edodes mycelium cultivated under the submerged conditions in Se-enriched medium, and to investigate their monosaccharide composition....

  • In this chapter attention is focused on a representative volume of the reactor. This volume contains one single fluid phase only. It is uniform in composition and temperature. If the reactor is spatially uniform, the representative volume is the total volume; if not, the representative volume is limited to a differential element — a “point”.

  • This book has two parts. The first part talks about general characteristics of the World Trade Organisation (WTO) as well as common steps that have to be taken during the accession process. Theoretical studies related to the WTO activities are also presented. Finally, Part I of this book discusses one of the most useful methods of examining economic consequences of being WTO member, namely Computable General Equilibrium (CGE) Models. Part II continues analysis and shows application of CGE model to a specific case study.

  • VNU Journal of Science, Natural Sciences and Technology 26 (2010) 161-164 Fresh leaves of Litsea glutinosa (Lour.) C. B. Rob. from Ha Tinh were steam distilled to produce an oil in 0.15% yield. The essential oil was analysis by a combination of capillary GC and GC/MS. Seventy eight compounds were detected in the oil, of which more than 95.18% were terpenoids. The major components were (E)-β-ocimene (13.35%), β-caryophyllene (27.20%) and bicyclogermacrene (18.16%).

  • Stability is a basic concern in both design and analysis of load-carrying systems and constitutes a major topic in the field of engineering science and mechanics. Since structural instability may lead to catastrophic failure of engineering structures, stability requirements must be satisfied besides requirements related to material failure. Knowledge on stability is of great importance in the areas of Civil Engineering, Mechanical Engineering and Aerospace Engineering; and all these disciplines have their own literature related to the subject....

  • In this study, the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength, tensile modulus, module Weibull and elongation to break of the fiber, the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz, power 50 W and treatment time of 5 minutes, after air-plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double (101.1% and 101.

  • A new approach of predicting structural classes of protein domain sequences is presented in this paper. Besides the amino acid composition, the composition of several dipeptides, tripeptides, tetrapeptides, pentapeptides and hexapeptides are taken into account based on the step-wise discriminant analysis. The result of jackknife test shows that this new approach can lead to higher pre-dictive sensitivityand specificityfor reduced sequence similaritydatasets.

  • This paper describes the main features of our tool called “Legal Taxonomy Syllabus”. The system is an ontology based tool designed to annotate and recover multi-lingua legal information and build conceptual dictionaries on European Directives. Vogel, 2004) and ontologies engineering (Klein, 2001), are the following ones: 1) Terms and concepts must be distinguished; for this purpose, we use lightweight ontologies, i.e. simple taxonomic structures of primitive or composite terms together with associated definitions. ...

  • This paper describes a compositional semantics for temporal expressions as part of the meaning representation language (MRL) of the JANUS system, a natural language understanding and generation system under joint development by BBN Laboratoires and the Information Sciences Institute. 1 The analysis is based on a higher order intansional logic described in detail in Hinrichs, Ayuso and Scha (1987). Temporal expressions of English are translated into this language as quantifiers over times which bind temporal indices on predicates.

  • In another recent study by our group (Gürlek et al. 2009) similar salivary ICTP levels were detected in smoker, non-smoker and ex-smoker patient groups with similar clinical periodontal findings. Smoking status was confirmed by salivary cotinine analysis but there was no clinically healthy control group in that study and the number of teeth present, average probing depths and attachment levels were all similar in the three study groups. There were no significant differences in saliva ICTP concentrations between the smoker and non-smoker patient groups.

  • The amount of energy that people used in the past two decades is equivalent to the total amount of energy in the past. This huge increase of energy use has been made possible by extending depletion of fossil reserves and is clearly unsustainable. Does it mean that once the reserves are exhausted the amount of energy available to humans would be similar before the era of fossil fuels? Not necessarily. Currently, the total energy used by mankind No. 1/5500 fraction of the total incident solar energy on earth....
