<P>Cobitis nalbanti, new species, is described from the South Korean Han and Geum Rivers, draining to the Yellow Sea. It differs from its congeners by having a wide, ovoid lamina circularis; rounded scales with a large, slightly-displaced focal zone; a relatively long, protruded snout; the suborbital spine not reaching the center of the eye; the mandibular barbel not reaching the anterior edge of the eye; usually 12-14 dark brown blotches in the fourth Gambetta’s zone; a single elongated black spot on the upper part of the caudal-fin base; the only streak on the head running from the tip of the snout to the nape, across the eye; 2n=48-51 and NF=66. Cobitis nalbanti was previously identified as C. lutheri. Morphological analysis of C. lutheri shows that it is distinct in having a short obtuse snout, the suborbital spine reaching the center of the eye, the mandibular barbel reaching the anterior edge of the eye, usually less than 12 dark brown blotches in the fourth Gambetta’s zone, two spots at the caudal-fin base, several dark streaks on the head, and 2n=50, NF=70. A lectotype is selected for C. lutheri. Cobitis lutheri has a wide distribution in the Amur River basin, several rivers flowing into the Sea of Japan (East Sea), and in the northern part of Sakhalin Island. </P>
Heat Treatment Influence on the Structural Properties of Supported Ni Nanoclusters

Ni nanoclusters supported on Al2O3 were prepared using a coprecipitation method. A heat treatment at differenttemperatures was applied. The obtained samples were analyzed by X-ray diffraction (XRD), X-rayabsorption spectroscopy and X-ray photoelectron spectroscopy in order to determine their global, local andelectronic structures. The average particle size, the mean squares of the microstrain, the particle size andmicrostrain distribution functions of the supported Ni nanoclusters were determined by the XRD methodusing a generalized Fermi function for the approximation of the X-ray line. The recrystallization inducedduring the heat treatment process was analyzed. The present study indicated strong deformation of thelocal structure of the active metal in all of the samples investigated due to the metal-support interactionand the effects of the small particle size. Electronic structural investigations showed the presence of Ni ina metallic state as well as Ni2+ on the cluster surfaces.

This paper introduces a non-automatic device to apply biaxial stretch and investigates the effect of biaxial stretchand domestic washing on air permeability of polyamide-elastane knitted fabrics for sportswear. Air permeability of theselected fabrics significantly increased upon biaxial stretch, regardless the fabric type and stretch level (5 % or 10 %) applied. Generally, air permeability of relaxed fabrics decreased due to slight shrinkage that occurred upon washing, but domesticwashing was not found to have a statistical significant influence on air permeability of the selected fabrics. The manualdevice proposed applies stretch in one or two directions, it is robust and easy to handle, and fabric preparation is quitestraightforward. The fabric holder used in this study is particularly suited to the head of the air permeability tester and thelevel of stretch applied depends on type of fabric.

The paper describes the configuring and analysis of a class of generalized reconfigurable 2-axis parallel kinematic machine (R2PKM). A generalized model which is used for solving inverse and direct kinematic problem is presented. Generalized equations that present the solutions of kinematic problems are derived and they are valid for any configuration of R2PKM. Characteristic configurations of the mechanism are given as an example of the concept realization. For selected configurations, workspaces are defined and possible singular positions of the mechanism are analyzed. Optimization of the mechanism legs length was performed using the condition number. Determination of optimal legs length has been shown for several different configurations of the parallel mechanism. Control and programming system is configured and experimental prototype of R2PKM is realized. Verification of the configured machine, configured control and programming system was performed on the virtual machine and also on the prototype of the machine by drawing several different contours.
A Note on Subnormal and Hyponormal Derivations
Lauric, Vasile Department of Mathematics 2008 Kyungpook mathematical journal Vol.48 No.2
In this note we prove that if A and $B^*$ are subnormal operators and is a bounded linear operator such that AX - XB is a Hilbert-Schmidt operator, then f(A)X - Xf(B) is also a Hilbert-Schmidt operator and $${\parallel}f(A)X\;-\;Xf(B){\parallel}_2\;\leq\;L{\parallel}AX\;-\;XB{\parallel}_2$$, for f belonging to a certain class of functions. Furthermore, we investigate the similar problem in the case that S, T are hyponormal operators and $X\;{\in}\;\cal{L}(\cal{H})$ is such that SX - XT belongs to a norm ideal (J, ${\parallel}\;{\cdot}\;{\parallel}_J$) and prove that f(S)X - Xf(T) $\in$ J and ${\parallel}f(S)X\;-\;Xf(T){\parallel}_J\;\leq\;C{\parallel}SX\;-\;XT{\parallel}_J$, for f in a certain class of functions.

An election is a process of making decision when people choose a person to hold official offices. It is one of the usual tools of modern democracy. With the help of elections, it fills offices in the legislature for regional and local government. The practice of holding elections to bodies of state power of the subjects of the Russian Federation proved that at present the federal legislative regulation and control of the compliance with the electoral rights of citizens on behalf of the federal bodies of state power are required in order to hold free and democratic elections in the subjects of the Russian Federation. It allows for the constraint of steady negative trends experienced lately, which relate to limiting the electoral rights of citizens in the election legislation of the subjects of the Russian Federation and organizing the election process at a regional level. The author, Tatyana Vasileva, in this article analyzing communicative technologies in the electoral process of Primorsky territory, studying main strategies and tactics of the electoral procedure.
