Renewable energy sources based on solar radiation, wind energy, geothermal energy, and biomass energy have now reached the level of industrial application. A new way to generate electricity using low-potential heat is to install a hydro-steam turbine. In hydro-steam turbines, hot water is supplied directly to turbine rotor nozzles without prior separation into steam and water in separators, which significantly increases the efficiency of hot water energy use. Such turbines are suggested to be used as autonomous energy sources in geothermal heating systems, heating water boilers and cooling systems of chemical reactors, metallurgical furnaces, etc. The authors conclude that the installation of hydro-steam turbines in heating plants and process boiler plants can also be effective if the used exhaust steam-water mixture at the turbine outlet is used to heat the network water or as return water.

A Gram-negative, aerobic, rod shaped, non-spore-forming bacterial strain, designated Dae08^T, was isolated from sediment of the stream near Daechung dam in South Korea, and was characterized in order to determine its taxonomic position, using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Dae08^T belongs to the family Xanthomonadaceae of the Gammaproteobacteria, and is related to Lysobacter brunescens ATCC 29482^T (97.3%). The phylogenetic distances from any other species with validly published names within the genus Lysobacter were greater than 3.7%. The G+C contents of the genomic DNA of strain Dae08^T was 69.3 mol%. The detection of a quinone system with Q-8 as the predominant compound and a fatty acid profile with iso-C_15:0, iso-C_17:1 ω9c, iso-C_17:0, iso-C_16:0, and iso-C_11:0 3-OH as the major acids supported the affiliation of strain Dae08^T to the genus Lysobacter. DNA-DNA relatedness between strain Dae08^T and its phylogenetically closest neighbour was 28%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Dae08^T (= KCTC 12600^T) should be classified in the genus Lysobacter as the novel species, for which the name Lysobacter daecheongensis sp. nov. is proposed.

Ischemic and reperfusion injuries of the heart underlie the pathogenesis of acute myocardial infarction (AMI) and sudden cardiac death. The mortality rate is still high and is 5–7% in patients with ST-segment elevation myocardial infarction. The review is devoted to pharmacological approaches to limitation of ischemic and reperfusion injuries of the heart. The article analyzes experimental evidence and the clinical data on the effects of P2Y12 receptor antagonists on the heart’s tolerance to ischemia/reperfusion in animals with coronary artery occlusion and reperfusion and also in patients with AMI. Chronic administration of ticagrelor prevented adverse remodeling of the heart. There is evidence that sphingosine-1-phosphate is the molecule that mediates the infarct-reducing effect of P2Y12 receptor antagonists. It was discussed a role of adenosine in the cardioprotective effect of ticagrelor.
Adaptive asymptotically efficient estimation in heteroscedastic nonparametric regression
Leonid Galtchouk,Sergey Pergamenshchikov 한국통계학회 2009 Journal of the Korean Statistical Society Vol.38 No.4
The paper considers some asymptotic properties of the adaptive procedure proposed in authors' paper, 2007, for estimating an unknown nonparametric regression. We show that the procedure is asymptotically efficient for quadratic risk, i.e. the asymptotic quadratic risk of the procedure coincides with the corresponding Pinsker constant provided the sharp lower bound for the quadratic risk over all possible estimators.
Australia and the DPRK: The Sixty Years of Relationship
Leonid A. Petrov 인하대학교 국제관계연구소 2008 Pacific Focus Vol.23 No.3
The record of relations between Australia and the Democratic People’s Republic of Korea (DPRK) is one of the oddest and most chequered in diplomatic history. A short period of recognition and cultural cooperation was followed by the resurgent nuclear crisis and the drug-smuggling ship incident, which proved to be hard tests for this shaky relationship. The closure of the DPRK embassy to Australia in January 2008 once again left the public confused and the pundits guessing about the true reasons behind this quiet démarche. This paper examines the major ups and downs in the history of Australia-DPRK bilateral relations and offers some clues as to what might have been wrong in Australian policy and attitudes toward the isolated communist nation. Australian involvement in the US-led Proliferation Security Initiative and the ban on the supply of “luxury goods” to North Korea will be discussed. Interviews with serving and veteran diplomats, declassified DFAT archival material and international media reports provided the basis for this research.
