The reactivity of different heteroscorpionate ligands based on bis(pyrazol-1-yl)methane, with different iridium-(i) and -(iii) precursors is reported. The reaction of the heteroscorpionate lithium salts "Li(bdmpza)", [bdmpza = bis(3,5-dimethylpyrazol-1-yl)acetate], "Li(bdmpzdta)" [bdmpzdta = bis(3,5-dimethylpyrazol-1-yl)dithioacetate] and "Li(S)-mbpam" [(S)-mbpam = (S)-(-)-N-α-methylbenzyl-2,2-...

MnMX (M = Co or Ni, X Si Ge) alloys, experiencing structural transformation between Ni2In-type hexagonal and TiNiSi-type orthorhombic phases, attract considerable attention due to their potential applications as room-temperature solid refrigerants. Although lots of studies have been carried out on how tune this obtain large entropy change in a wide temperature region, the crystallography marten...

INTRODUCTION Questionnaires to evaluate hand function are variable in the number of items, domains and diseases in which they had been previously used. OBJECTIVES a) To translate to Spanish and validate the m-SACRAH and AUSCAN questionnaires; b) to do a transcultural adaptation of DASHe, previously validated in Spain), and c) to compare them and the Cochin questionnaire (previously validated ...

background and objectives: dietary approaches to stop hypertension (dash) eating pattern, a diet rich in fruits, vegetables, whole grains and low-fat dairy with a reduced content of sodium, saturated fat, and total fat is introduced as an appropriate diet for hypertension. this eating pattern was basically designed to normalize blood pressure in patients with hypertension, and a large body of d...

Atomistic-level understanding of the interaction of α,β-unsaturated aldehydes and their derivatives with late transition metals is of fundamental importance for the rational design of new catalytic materials with the desired selectivity towards C[double bond, length as m-dash]C vs. C[double bond, length as m-dash]O bond partial hydrogenation. In this study, we investigate the interaction of acr...

Let H be a hexagonal system. The Z-transformation graph Z(H) is the graph where the vertices are the perfect matchings of H and where two perfect matchings are joined by an edge provided their symmetric difference is a hexagon of H (Z. Fu-ji et al., 1988). In this paper we prove that Z(H) has a Hamilton path if H is a catacondensed hexagonal system. A hexagonal system [ll], also called honeycom...
