The aims of this study are to investigate the association between: (i) forward head posture (FHP) and pressure pain thresholds (PPTs); (ii) FHP maladaptive cognitive processes; (iii) neck characteristics in university students with subclinical pain.A total 140 students, 90 asymptomatic 50 pain, entered study. Demographic data, anthropometric FHP, PPTs were collected for both groups. In addition, characteristics, catastrophizing, fear movement assessed participants pain. was characterized by...
The iron(III) μ-oxo bridged dimeric polyoxometalate [(PW(11)O(39)Fe)(2)O](10-) was isolated by reacting the transition metal monosubstituted Keggin anion [PW(11)O(39)Fe(H(2)O)](4-) and ionic liquid 1-butyl-3-methylimidazolium bromide, (Bmim)Br, at pH 5.5. crystal structure of (Bmim)(10)[(PW(11)O(39)Fe)(2)O]·0.5H(2)O (1) (monoclinic, space group P2(1)/n, Z = 4) determined single X-ray diffraction. By changing reaction conditions, (Bmim)(4)[PW(11)O(39)Fe(H(2)O)]·H(2)O (2) obtained, whilst...
Several novel compounds with the non-linear optical chromophore 2-amino-5-nitropyridine (2A5NP) and Keggin polyoxoanions (alpha-isomers), having general formula (2A5NP)(m)H(n)[XM12O40].xH2O, M = Mo, W, were synthesised. Compounds obtained X P, n 3, m 3 4 Si, (x 2-6). Thus, for each of anions [PMo12O40]3- [PW12O40]3- two different obtained, same anion organic counterpart but a stoichiometric ratio. These presented charge transfer properties thermal stability. All characterised by...

Glycosaminoglycans have quietly transitioned from biomaterials to advanced functional materials for energy devices and flexible electronics. Gathered here are 45 years of research highlighting both fundamental studies recent advances trends.
The thermal conductivity of three mixtures nitrogen and cyclopentane is measured using a transient hot wire method, at temperatures between 315.14 395.89 K, pressures up to 0.53 MPa. These are important in the evaluation evolution insulation capacity closed-cell polyurethane foams considering their aging during respective applications’ total life time. experimental data correlated with Wassiljewa mixing rules as modified by Mason Saxena, predicted extended corresponding states theory (ECST),...
The metallation of aromatics is a convenient approach to the functionalization unsaturated scaffolds1. Polyfunctional ary halides are high importance as agrochemicals, pharmaceuticals and building blocks. Recently, mixed lithium/magnesium amides such TMPMgCl.LiCl TMP2Mg.2LiCl have proven be interesting bases for arenes under mild conditions. In this work we wish report use magnesium magnesiation several haloaromatics oxazolines subsequent reactions with electrophiles.
