Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...

An undercooled liquid-phase (L-phase) can undergo a first order configurational phase transition to either crystal (X-phase) or metastable, configurationally heterogeneous, rigid glassy (G-phase). To investigate the underlying mechanism of L-G transition, we employ molecular dynamics simulations study G-phase formation in binary Cu-Ag system. We find that is driven by reduction local distortion...

the thermodynamic functions such as enthalpy (h), gibbs free energy (g) and entropy (s) ofpyrazole was theoretically studied at 5 different temperatures 25, 30, 35, 40 and 45°c by usinggussian o3, software. first, the structural optimization of isolated pyrazole was done in the gas phaseby appling the density functional theory (b3lyp) level with 3-21g, 6-31g and 6-31+g(d) basissets. moreover, v...

DNA of replication foci attached to the nuclear matrix was isolated from Chinese hamster ovary cells and human HeLa cells synchronized at different stages of the G(1) and S phases of the cell cycle. The abundance of sequences from dihydrofolate reductase ori-beta and the beta-globin replicator was determined in matrix-attached DNA. The results show that matrix-attached DNA isolated from cells i...

the thermodynamic functions such as enthalpy (h), gibbs free energy (g) and entropy (s) of serineand threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using gussian o3, software. first, the structural optimization of isolated serine andthreonine were done in the gas phase by using the hartree-fock (hf) level of theory with 3-21g, 6-31g and 6-3...

using the density functional theory (dft) level by means of 3-21g, 6-31g and 6-31+g (d) basissets, the structural optimization of isolated pyrazole and pyrazoline was done in the gas phase. then,the calculation about the solvent effect on the stability energies of pyrazole and pyrazoline wasperformed for the ten solvents using pcm model method at b3lyp/6-31+g(d) and then the dielectriceffects o...

Machado-Joseph disease (MJD) is an inherited neurodegenerative disorder caused by the expansion of the polyglutamine stretch in the MJD gene-encoded protein, ataxin-3. Using a series of deletion constructs expressing ataxin-3 fragments with expanded polyglutamine stretches, we observed aggregate formation and cell death in cultured BHK-21 cells. The cytotoxic effect of N-terminal-truncated atax...
