Optimization and improvement of sialon ceramics with new heat treatment techniques
(1997)
Sialons are of interest for use as engineering materials for high temperature (>1000°C) applications becuase they retain good mechanical properties at these temperatures, whereas competing metallic materials are weak and ...
alpha ->beta sialon transformation in calcium-containing alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)
Recent studies on rare earth densified a-sialon ceramics have shown that the resulting alpha-sialon product, present either as a single phase or in conjunction with beta-sialon, is unstable when heat treated at lower ...
Microstructural characterization of surface layers formed on a low alloy steel during erosion - oxidation in a fluidized bed
(Chapman Hall LTD, 1997)
Low alloy steel specimens were subjected to erosion-oxidation in a simulated fluidized bed environ ment in the range 100-600 degrees C. Transmission electron microscopy was carried out on the surfaces which experienced ...
The effects of n-ras oncogene expression on PDGF-BB stimulated responses in cultured mouse myoblasts
(1995)
The role of the ras oncogene in the signalling pathway triggered by platelet-derived growth factor BB (PDGF-BB) has been investigated in a cell line which normally differentiates into myotubes. Following the activation of ...
Checklist of Tabanidae (Diptera) from Turkey

After a review of the literature on the Tabanidae fauna of Turkey, it was found that 156 species and 12 subspecies have been reported. Twelve of the species are from the subfamily Pangoninae. 19 species and 2 subspecies ...
Cytosolic $Ca^{2+}$ levels in CO25 myoblast cells bearing a human N-ras oncogene after stimulation by thapsigargin and growth factors
(1999)
CO25 miyoblast hücrelerinin, thapsigargin (ThG), bombesin ve epidermal büyüme faktörü (EGF) ile stimülasyonları sonucunda hücre içi kalsiyum [$Ca^{2+}$ ]i seviyeleri araştırılmıştır. ThG, çoğunlukla hücre içi kalsiyum ...
The geometry of self-dual two-forms
(Amer Inst Physics, 1997)
We show that self-dual two-forms in 2n-dimensional spaces determine a n(2)-n+1-dimensional manifold S-2n and the dimension of the maximal linear subspaces of S-2n is equal To the (Radon-Hurwitz) number of linearly independent ...
