In an abelian category, a commutative quadrangle is called bicartesian if its diagonal sequence is short exact, i.e. if it is a pullback and a pushout. A commutative quadrangle is bicartesian if and only if we get induced isomophisms on the horizontal kernels and on the horizontal cokernels. In a triangulated category in the sense of Verdier [3, Def. 1-1], a commutative quadrangle is called hom...

Current hydration assessments involve biological fluids that are either compromised in dehydrated individuals or require laboratory equipment, making timely results unfeasible. The eye has been proposed as a potential site to provide a field-based hydration measure. The present study evaluated the efficacy and sensitivity of intraocular pressure (IOP) to assess hydration status. Twelve healthy ...

introduction the mahour exploration area is a polymetallic system containing copper, zinc and silver. the mineralization can be seen in two forms of veins and disseminations. this area is structurally within the lut block, west of deh-salm village. recent exploration work and studies carried out by geologists on this volcanic-plutonic area of lut demonstate its importance indicating new reserve...

A generalized quadrangle of order s ≥ 2 is isomorphic to W (s) if and only if there is a hyperbolic line every point of which is regular. This is a characterization of the symplectic generalized quadrangle W (s) which only needs the existence of s + 1 regular points (in a nice position).

INTRODUCTION Precambrian rocks in the Tusas Mountains range from nearly monomineralic quartzite, in which the principal result of metamorphism has been simple recrystallization, through locally metasomatized schist and gneiss profoundly modified by potash-rich fluids during the intrusion of pegmatite. Texturally, the rocks range from schist and phyllite containing penetrative and pervasive clea...

Abstract Background We describe a “stability-indicating liquid chromatography” technique for the estimation of dimethicone (DEC) and dicyclomine hydrochloride (DEH) in established tablet formulations. Individual quantification DEH DEC was reported. But simultaneous lacking. were analysed on an “XTerra C 18 column (250 mm × 4.6 mm, 5 μm)” with mobile phase solvent run isocratically 0.1M K 2 HPO ...
