Influence of material and gear parameters on the safety of gearing in metallurgical industry

This paper deals with the appropriate choice of parameters to obtain the desired level of safety of gears in a gearbox to drive the conveyor in the metallurgical industry under increased load. Steel with surface hardness up to 350 HBW, or heat treated steel with hardness of 500 - 650 HBW are used. As a final heat treatment are used surface hardening, cementation and hardening, nitridation. Good properties of heat-treated steels are at the correct thickness of the heat-treated layer of the tooth. Results are presented for dual-ratio gearbox with spur gears from operation of an integrated steel company

Photometry of Some Recent Gamma-ray Bursts

We present the results of the optical, X-ray and gamma-ray analysis of some recent GRBs. The data were obtained by the automated P60 telescope and the Swift telescope (UVOT, XRT and BAT). We present some example fits for the lightcurves. The data reduction and the investigations were made by the Konkoly Observatory HEART group (http://www.konkoly.hu/HEART/index.html).Comment: 4 pages, 1 figure, appeared in GAMMA RAY BURSTS 2010, AIP Conference Proceedings, Volume 1358, pp. 134-137 (2011

Experimental identification of piezo actuator characteristic

This paper deals with piezoelectric material, which can be used as actuator for conversion of electrical energy to mechanical work. Test equipment has been developed for experimental testing of the piezoactuators. Piezoactivity of this actuator has non-linear characteristic. This type of actuator is used for in-pipe mechanism design

Addition of Synthetic Feeding Attractant Increases Catches of Rhagoletis batava Hering and Carpomyia schineri Loew. in Fluorescent Yellow Sticky Traps

The addition of the synthetic Rhagoletis feeding attractant (consisting of ammonium carbonate and ammonium acetate, developed previously for Rhagoletis cerasi L.) to both fluorescent yellow or transparent sticky traps significantly increased catches of the fruit flies Rhagoletis batava Hering (pest of sea buckthorn) and Carpomyia schineri Loew. (pest of rose hips). Traps with lures were detecting the occurrence of both species 1–2 weeks before as compared to traps without lure, and quantitative aspects of the flight could be followed in more detail in traps with lure. Thus in detection and monitoring surveys, where sensitivity of the trap is highly important, the use of traps with synthetic lure added is strongly recommended

Use of supplementary phenotype to identify additional rheumatoid arthritis loci in a linkage analysis of 342 UK affected sibling pair families

<p>Abstract</p> <p>Background</p> <p>Although rheumatoid arthritis has been shown to have moderately strong genetic component, both linked loci identified in linkage analyses and susceptibility variants from association studies are short of adequately accounting for a comprehensive catalogue of the molecular factors underlying this complex disease. The objective of this study was to use supplementary phenotype based on cumulative hazard of rheumatoid arthritis to identify linkage evidence for new and additional rheumatoid arthritis loci in a genome-wide linkage analysis of 342 affected sibling pair families from the United Kingdom.</p> <p>Methods</p> <p>Using proportional hazards model, we estimated cumulative hazard of rheumatoid arthritis and then used it as a quantitative trait in a non-parametric multipoint variance component linkage analysis with 353 microsatellite markers distributed across the 22 autosomal chromosomes.</p> <p>Results</p> <p>We identified 3 new loci with genome-wide suggestive linkage evidence for rheumatoid arthritis on 9q21.13, 15p11.1 and 20q13.33. Our results also confirmed previously reported linkage evidence in the HLA-DRB1 region on chromosome 6 and on locus 1q32.1.</p> <p>Conclusion</p> <p>This study demonstrates the potential for information gain through the use of supplementary phenotypes in genetic study of complex diseases to identify new and additional potential linked loci that are not detected by linkage analysis of traditional phenotypes; and our results provide further evidence of the involvement of multiple loci in the genetic aetiology of rheumatoid arthritis.</p
