A series of uranyl(VI) dihalide complexes UO2X2L2 (X = Cl, Br) supported by organic amide ligands (L = R'C(O)NR2; R' = i-Pr; R = i-Pr, i-Bu, s-Bu) offers the versatile combination of facile synthesis using benchtop methods, air-stable crystalline solids obtained in high yield, high solubility in common organic solvents and tunable steric/electronic properties.

We present a five dimensional supersymmetric SO(10) model compactified on an orbifold S/Z2 ×Z ′ 2. The gauge symmetry G422 ≡ SU(4)c×SU(2)L×SU(2)R, realized on one of the fixed points (branes), is spontaneously broken to the MSSM via the higgs mechanism. Employing a flavor U(1) symmetry and suitably extending the ’matter’ sector enables us to understand large mixings in the neutrino sector via a...

Melissa officinalis L. (Labiatae) traditionally used in treating neurological disorders has also been identified as a memory-enhancing herb. The extract of M. officinalis has a cholinergic property. The role of basal forebrain cholinergic neurons, the neurons that are destroyed in Alzheimer's disease (AD), in learning and memory, is also well known. The aim of this study is to investigate the r...

The chemical composition and bioactive properties of two plants (Calendula officinalis L. and Mentha cervina L.) were studied. Their nutritional value revealed a high content of carbohydrates and low fat levels, and very similar energy values. However, they presented different profiles in phenolic compounds and fatty acids; C. officinalis presented mainly glycosylated flavonols and saturated fa...
