New methods of generation of electrophilic iodine in neutral and weakly acidic media
- Trang 314-316
We have developed new methods to generation of electrophilic iodine on the base iodine chloride and different salts: ICl+MeX/spl rarr/I/sup +/X/sup -/+MeCl, Me=Ag/sup +/, Pb/sup +/, Na/sup +/; X=CF/sub 3/COO/sup -/, CH/sub 3/COO/sup -/. Iodinating ability of obtained reagents has been studied on aromatic (including polycyclic) and heterocyclic compounds.

Estimation of quality of life in Korean cities
- Trang 93-95
This paper estimated the level of quality of life of 74 cities in Korea. In order to figure out the quality of life in those cities, the author estimated wage and housing expenditure functions through the hedonic method. By using the coefficients of the estimated these functions, he then calculated 15 implicit factor prices associated with quality of life. For this, Korean Household Panel Data and......

Recognition of free gymnastics using human body feature points from silhouette and skin region
- Trang 150-154
Many motion recognition algorithms use information that is acquired under forced-conditions such as adhered sensors on body joints or the specialized place where the motion analysis equipment is previously set for extracting and tracking features of human motion. This paper presents a recognition algorithm of human motion in an outdoor environment without any sensors attached on a human body. The ......

Analysis of environment ecological parameters by means of tree-rings
- Trang 208-210
Climate is the main factor limiting capability of forest and communities in many areas of the world. By means of tree-ring analysis it is possible to make a reconstruction of many important climatic and hydrological characteristics. This paper describes a method of determination of climatic parameters with the help of tree-rings analysis.

Feynman diagrams for Lippman-Schwinger equation with singular potential
- Trang 240-245
In this note we consider the direct problem for LS with point like nonhomogeneous. The diagram technique allows us to classify all scattering diagrams and to describe wave structure of the LS solution.

The way of ladder diagram analysis for small compact programmable controller
- Trang 169-173
The paper presents the considerations relating to the methods of analysis of a ladder diagram created for a small programmable controller (PLC) of compact type which is equipped with a simple keyboard for entry of such a diagram. Because of the fact that the compact PLC was built using a standard microcontroller with small calculation power the authors met difficulties with the translation of the ......

New requirements of matching network physical realizability
- Trang 359-362
A new definition of the zero of transmission of the load is introduced in this. paper. New requirements of matching network physical realizability - in the form of restrictions on expansion coefficients of network functions are obtained as an alternative to classical ones, that allow to synthesize matching networks and to solve the problem of the limited broadband matching in the simplest way.

Effects of structural damping on composite panel flutter
- Trang 11-14
The governing equation for the analysis of panel flutter of composite plates including structural damping is derived using the energy method. The classical lamination theory is applied to structural modeling and the eigenvalue problem is obtained by the Rayleigh-Ritz method. The unsteady aerodynamic load in supersonic flow is computed by the piston theory. The critical dynamic pressures for compos......

Thermoanalytical study of energy saturated electroexplosive nanopowders
- Trang 317-319
The storage of excess superequilibrium energy occurs in final products of wire electrical explosion. This effect can be successfully used in different fields: in processes of combustion, sintering, and chemical reactions. In the present work, thermal analysis is suggested as a method for the determination of excess energy value. According to results of the thermal analysis, the excess energy for n......

Carbon catalysts for waste water oxidative treatment
- Trang 226-229
Catalytic oxidation of environmental contaminants by oxygen has been investigated in water phase at elevated temperatures and pressures. Chlorine and nitrogen containing substances in model solutions, real wastewater of chocolate factory and alcohol plant (-oxygen-containing compounds), petrochemical plant (-sulfurous substances), chemical-recovery plant (-ammonia, sulfurous substances) were used ......
