Abstract This article describes a novel pattern of interpretations associated with universal determiners like ‘each’ and ‘every’. It is demonstrated that these canonically distributive quantifiers can give rise to surprising collective readings when they quantify into sub-clausal constituents, especially other Determiner Phrases. For instance, ‘two cards from each player’ be understood pick out...
genetic diversity relationships of 50 isolates of cytospora schulzeri on apple from different parts of the semirom region were analyzed using 15 polymerase chain reaction (pcr) based markers, 7 random amplified polymorphic dnas (rapds) and 8 microsatellite primed polymerase chain reaction (mp-pcr). using 7 selected rapd primers 113 bands were generated, of which 81 bands were polymorphic (71.7%...
Conformational analysis of modeled cis-unsaturated chains in triunsaturated and symmetrical monounsaturated triglycerides has identified pseudo-linear chain orientations that allow lower molecular mechanical energies than are possible with conventional cis-chains. Energy plots recorded during bond rotations near the double bond show that energy barriers between linear and normal cis-configurati...
Differential scanning calorimetric (DSC) curves recorded for ornidazole drug during heating and cooling showed that the drug which melted around 86.1 degrees C undercooled to well below ambient room temperature of 27 degrees C during the cooling cycle. The undercooled melt kept in the freezer at 0 degree C for 10 days duration also remained in the viscous liquid form. This liquid on taking out ...
Polymorphism, in which there exist different crystal forms for the same chemical compound, is an important phenomenon in pharmaceutical manufacturing. In this article, a kinetic model for the crystallization of L-glutamic acid polymorphs is developed from experimental data. This model appears to be the first to include all of the transformation kinetic parameters including dependence on the tem...
Multiphase (MP) monoclinic and cubic Y2O3 nanoparticles, 40 nm in diameter, were densified by spark plasma sintering for 5–15 min and100 MPa at 1000 C, 1100 C, and 1500 C. Densification started with pressure increase at room temperature. Densification stagnated during heating compared to the high shrinkage rate in cubic single-phase reference nanopowder. The limited densification of the MP nano...
