We present a detailed study of the Herbig-Haro objects HH 80/81, twin working surfaces in the highly collimated outÑow driven by a luminous young star. High angular resolution emission line images obtained with the Hubble Space Telescope are used together with ground-based lowand high-dispersion spectroscopy, and proper motion measurements to provide a comprehensive picture of the structure and...

In the present study, the microstructural changes of a Nickel based superalloy Nimonic80A during a non-isothermal deformation were studied. Therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. The predicted results were validated through experimentalmicrostructural studies. The results ...

Tssk2, a member of the testis-specific serine/threonine kinase (TSSK) family, is expressed predominantly in the testis and is crucial for the formation and function of sperm cells in the mouse. Targeted deletion of Tssk1 and Tssk2 in male chimeric mice caused infertility because of haploinsufficiency of the genes. Therefore, it is reasonable to postulate that mutations in the human homolog TSSK...

The calibration scheme of the CERES TPC has been improved with respect to the data reconstruction used in [1], which leads to a remarkable decrease of the systematic error for the 80A GeV and 158A GeV data set. Figure 1 shows the new results of the HBT parameters for collisions at 80A GeV in the Bertsch-Pratt parametrization as a function of the transverse pair momentum k⊥. The new values are c...

The human DNA mismatch repair genes hMSH2 and hMLH1 are responsible for the development of hereditary nonpolyposis colorectal cancer (HNPCC). Although genetic alteration of the coding region of hMSH2 and hMLH1 has been well investigated in HNPCC patients, the regulatory regions of these genes have been poorly investigated, though recent studies have defined and characterized the core promoter r...

Investigations were conducted on hot corrosion of Nickel base, NIMONIC-90 at 675°C and 725°C. The tests were carried out on small test coupons coated with a chemical containing Sodium sulphate and Sodium Vanadate which is representative of the corrosive deposit that usually forms during service in the coal fired boiler and the likes operating in marine atmospheres. Corrosion rates were measured...
