We show that given an ideal a \mathfrak {a} generated by regular ...

This study is focused on forming a fibrous-zinc oxide/ polyvinylidine fluoride (ZnO/PVDF) nanocomposite and characterizing its dielectric behavior. The nanocomposite is prepared in two steps. First, a network of nanoscale diameter ZnO fibers is produced by sintering electrospun PVA/Zinc Acetate fibers. Second, the ZnO fibrous nonwoven mat is sandwiched between two PVDF thermoplastic polymer fil...

Fatty acid peroxides have been found in the atherosclerotic human aorta. Glavind found a correlation between the extent of the atherosclerotic changes and the content of lipid peroxides. These lipid peroxides are very toxic to the tissues. There are several compounds in the tissues to counteract the toxicity of peroxides in vivo, i.e. SH compounds, ascorbic acid, or tocopherol. · It may be infe...

L’Association des psychiatres du Canada vient de publier un livre intitulé Psychiatry in Canada: 50 years (1), afin de célébrer les 50 ans de son organisation. L’ouvrage, compos de 16 chapitres, tente de tracer l’évolution de la pratique psychiatrique qui tient compte des différents mouvements de la discipline. Le chapitre 13 aborde la recherche en psychopharmacologie au Canada. Ce court chapit...

We look at a contrasting picture where some piece of functional/semantic information, namely tense, may be deened morphologically by tense innection, or else compositionally in syntax (in conjunction with innection on syntactic items). The question that is at issue is how to represent analytic tense formation to obtain a uniform functional structure for analytic and synthetic tense formation. S...

To maximize the controllable energy absorption of corrugation troughs as observed in the single sided corrugated (SSC) tube, we proposed and tested a new structure design, i.e., double-sided corrugated (DSC) tube made of Al 6060-T6 aluminum alloy or CF1263 carbon/epoxy composite. Finite element models were developed to test the mechanical advantage of the DSC tube in comparison with both SSC an...

Fluid flow analyses for porous media are of great importance in a wide range of industrial applications including, but not limited to, resin transfer moulding, filter analysis, transport of underground water and...

Boron carbide phases exist over a widely varying compos-itional range B(12+x)C(3-x) (0.06 < x < 1.7). One idealized structure corresponds to the B(13)C(2) composition (space group R-3m) and contains one icosa-hedral B(12) unit and one linear C-B-C chain. The B(12) units are composed of crystallographically distinct B atoms B(P) (polar, B1) and B(Eq) (equatorial, B2). Boron icosa-hedra are inter...
