CaO-Al₂O₃-SiO₂ (CAS) as a liquid phase was introduced into hydroxyapatite (HAp) to prepare bone scaffolds. The effects of the CAS content (1, 2, 3, 4 and 5 wt%) on microstructure and mechanical properties of HAp ceramics were investigated. The optimal compression strength, fracture toughness and Vickers hardness reached 22.22 MPa, 1.68 MPa·m1/2 and 4.47 GPa when 3 wt% CAS was added, which were ...

Les auteurs rapportent chez deux nourrissons, l'etude anatomo-clinique d'un cas de kystes alveolaires multiples,et d'un cas d'emphyseme lobaire congenital bilateral.Le troisieme cas concerne un kyste bronchog6nique du poumon gauche,decouvert a l'autopsie d'un nouveau-ne. Dans le quatrieme cas,un emphyseme geant du lobe superieur gauche,decouvert dans un contexte infectieux,a l'age de neuf mois,...

1. Investigations were made into the breast and leg muscle energy metabolism, and the quality of breast meat of turkeys after controlled atmosphere stunning or stun-killing (CAS) with various gas mixtures. In addition, the effect on meat quality of an increase in the chilling rate of turkey breast meat after hypercapnic or anoxic stun-killing was studied. 2. A total of 35 turkey toms within t...

The aim of the present research work was to determine the Phyto-constituents in fraction collected from ethanolic extract of Pericampylus glaucus leaf using the GC and Mass spectrometry. The Phyto-chemical screening of fraction from ethanolic extract of Pericampylus glaucus leaves were carried out with the help of Perkin-Elmer GC followed by Mass Spectrometry. The GC-MS chromatogram of Pericamp...

Naquelas obras, um serviços maior representatividade custos o esquadrias De acordo a Lei nº 14.133/2021 (a nov...

Spectroscopic observations at 2.4 – 45 μm of the young supernova remnant Cas A with the Infrared Space Observatory (ISO) Short Wavelength Spectrometer (SWS) reveal strong emission lines of O, Ne, Si, S, and Ar. These lines are observed at high velocities (several 10 km s), and are therefore associated with the supernova ejecta known as the fast-moving knots (FMKs). Continuum emission from dust ...

The early Pliocene shoaling of the Central American Seaway (CAS), ~4.7-4.2 million years ago (mega annum-Ma), is thought to have strengthened Atlantic Meridional Overturning Circulation (AMOC). The associated increase in northward flux of heat and moisture may have significantly influenced the evolution of Pliocene climate. While some evidence for the predicted increase in North Atlantic Deep W...

conclusions presence of cae in patients with cas increases its cardiovascular event rate. isolated cae is not a benign finding and mi can occur. risk factors of cae are similar to cas, but c/s is more associated with cae than cas. dm is seen in cae patients less than cas. results hypertension (htn), dyslipidemia (dlp), and male sex were matched in both groups without significant difference. cig...

Simulating a cellular automaton (CA) for t time-steps into the future requires t serial computation steps or t parallel ones. However, certain CAs based on an Abelian group, such as addition mod 2, are termed linear because they obey a principle of superposition. This allows them to be predicted efficiently, in serial time O(t) or O(log t) in parallel. In this paper, we generalize this by looki...
