N(1)-Hexyl substituted pyrimidines were shown to present solubility properties closer to the real bases than the commonly used methyl and ethyl derivatives, yielding bi-layered structures in the solid state. The study of their coordination capabilities, mainly with Ag(I) and Hg(II), is presented in order to prove their reactivity. A series of coordination complexes, namely, [Hg(N(1)-hexyl-5-flu...

In Computer-Aided Design, when creating the solid model of a part, the designer knows how the part will interface with other parts, however this information is not stored with the part model. For catalog parts, it would be useful to be able to embed this assembly information into the part model in order to automate the process of applying mating constraints, to reduce the assembly designer’s ef...

Domperidone is practically insoluble prokinetic drug; the systemic bioavailability of the drug following oral administration is only 13-17% because of extensive presystemic metabolism in the gut wall and liver. The applicability of the solid dispersion technique as a method for enhancing absorption of the drug through achieving better dissolution characteristics and better bioavailability for d...

A microtiter-based assay system is described in which DNA hairpin probes with dangling ends and single-stranded, linear DNA probes were immobilized and compared based on their ability to capture single-strand target DNA. Hairpin probes consisted of a 16 bp duplex stem, linked by a T(2)-biotin.dT-T(2) loop. The third base was a biotinylated uracil (U(B)) necessary for coupling to avidin coated m...

In this paper, as an application of fuzzy matroids, the fuzzifying greedy algorithm is proposed and an achievableexample is given. Basis axioms and circuit axioms of fuzzifying matroids, which are the semantic extension for thebasis axioms and circuit axioms of crisp matroids respectively, are presented. It is proved that a fuzzifying matroidis equivalent to a mapping which satisfies the basis ...

Solid pyrazole reacts with HCl gas to form pyrazolium chloride [H2pz]Cl, which reacts in the solid state, under grinding, with metal chlorides MCl2 (M = Co, Zn, Cu) to form the pyrazolium tetrachlorometallate salts [H2pz]2[MCl4] (M = Co 1, Zn 3, Cu 5). Salt 5 cannot be made in solution, and upon standing at room temperature spontaneously emits HCl to give the coordination compound [CuCl2(Hpz)2]...

background: the second processing cycle for adding the artificial teeth to heat-polymerized acrylic resin denture bases may result in dimensional changes of the denture bases. the aim of thisstudy was to evaluate the dimensional changes of the heat-polymerized acrylic resin denture bases with one and two-cycle processing methods. materials and methods: a metal edentulous maxillary arch was used...

Magnesium-related solid bases have long been considered catalysts with weak or medium basicity. Here we report the fabrication of Mg single-atom superbasicity for first time. A sublimation-migration-anchoring strategy is employed, in which net sublimated, transported by Ar, and trapped defective graphene (producing Mg1/G). Simulated experimental results demonstrate that single atoms are anchore...
