Methodology for knowledge portals development: background, foundations, experience of application, problems and prospects

The paper discusses an experience of using the methodology for the development of knowledge portals which provide systematization and integration of scientific and engineering knowledge and information resources as well as the content-based access to them. To provide a sufficiently complete and consistent representation of knowledge and information resources, their systematization and integration are performed on the basis of ontology. The suggested methodology has been successfully applied to the development of knowledge Internet portals on archaeology, computational linguistics, strength of materials and Antarctic data

оценка функции мышц передней брюшной стенки после герниопластики

The results of surgery in the group of patients with incisional hernias are evaluated. Hernioplasty with polypropylene mesh was performed in 22 patients. Electromyography was performed for abdominal wall muscles function estimation. High effectiveness of surgical treatment was established.В статье обсуждаются результаты хирургического лечения больных с послеоперационными грыжами.

Development of multilingual thesaurus by means of semantic technology

В докладе представлен подход к разработке многоязычного электронного тезауруса для произвольной предметной области, особенностью которого является использование в качестве инструмента разработки формальных и программных средств, предоставляемых семантической технологией, разработанной для построения порталов научных знаний. Благодаря тому, что эта технология базируется на онтологии, обеспечивается не только возможность расширения, целостность и непротиворечивость терминологической системы тезауруса, но и удобный доступ к его контенту. The paper presents an approach to the development of multilingual electronic thesaurus for an arbitrary domain. A feature of the approach is the use of the formal and software tools provided by the semantic technology that was developed for the construction of scientific knowledge portals

Improving Pastille Manufacturing TECHNOLOGY Using the Developed Multicomponent Fruit and Berry Paste

A method for manufacturing multicomponent fruit and berry paste based on apples, cranberries, hawthorn with a high content of pectin substances has been improved. A special feature of the technique is the concentration in a rotary film apparatus until a dry matter content of 28... 30 % under a mild mode during 25...50 s provided that the puree is preheated to 50 °C. The limiting shear stress for each type of raw material and the effective viscosity index for the samples of the formulations of the studied pastes have been established. It was found that the best properties are demonstrated by composition with the following formulation ratio of components: apple – 50 %; cranberries – 40 %; hawthorn – 10 %. That makes it possible to obtain pastes with the best chemical composition (the higher content of pectin substances, organic acids, ascorbic acid, etc.). The rational amount of adding 75 % of fruit and berry paste to replace apple puree has been determined and substantiated. That makes it possible to manufacture pastille with a high degree of structure formation, which is confirmed by the viscosity index of 616 Pa∙s, compared with control – 354 Pa∙s. A decrease in the mass fraction of dry substances by 5.0 %, an increase in acidity and reducing substances are ensured, which meets the requirements set by regulatory documents. This amount of paste provides for excellent organoleptic properties, i.e. it gives the products an even red color, pleasant taste, and smell. The developed technology expands the range of "healthy food" by partially replacing raw materials with a low content of physiologically functional components with a multicomponent composition, as well as provides for an increase in the pastille nutritional value. The use of sparing modes of concentration makes it possible to intensify the process of manufacturing a multicomponent paste, which indicates energy and resource-saving technolog
