We study normalization problems associated with use of perturbatively correlated ground-states in extended RPA schemes in the context of a specific but typical example. The sensitivity of the results to the amount of 2p2h admixtures to the correlated ground state is also investigated in terms of a modification of the standard perturbative approach.

BACKGROUND The aim of the study was to measure the content of methylated purines that appear as admixtures in uric acid stones. METHODS We analyzed urinary calculi from 48 residents of Western Pomerania who underwent surgery at the urology ward in Szczecin. Stone samples were dissolved in 0.1 mol/L NaOH. Extracts were diluted in 50 mmol/L KH(2)PO(4) and analyzed by reversed-phase HPLC with ul...

To study the influence of different mix proportions on fresh properties wet shotcrete, rheological and air content shotcrete with admixtures before pumping were measured. In addition, pressure drop along pipeline build-up thickness studied, relationship between pumpability sprayability was discussed. This paper attempts to reveal mechanism fluidity by means pictures. The results show that free ...

The present work presents focuses on the use of different admixtures for development rendering lime-based mortars with improved adhesion and durability, as well reduction cracking. To this aim, combinations an improver (ethylene–vinyl acetate copolymer, EVA), a water repellent agent (sodium oleate), viscosity enhancer (a starch derivative) mineral admixture (pozzolanic addition nanosilica or me...

BACKGROUND Naloxone may be administered in conjunction with morphine to reduce the risk of opioid-induced pruritis. Combining these drugs for coadministration may be beneficial, but little is known about their physical compatibility and stability in combined solutions. OBJECTIVE To describe the physical compatibility and stability of morphine sulphate and naloxone hydrochloride (at various co...

Soluble mucus glycoprotein (S-mucin) processed from the small intestines (ileal region) of freshly slaughtered pigs via homogenization, dialysis, centrifugation and lyophilization and their admixtures with type B gelatin were used to prepare cefaclor-loaded microspheres by the emulsification-crosslinking method. The microspheres were evaluated for the in vitro delivery of cefaclor in both simul...

Chemical admixtures are an essential ingredient of modern concrete mix, but many their molecular scale working mechanisms remain poorly described. In this respect, recent advances in computational methods, provide a unique opportunity to gain the needed level insights into mechanism action chemical cementitious systems. Such studies slowly increasing number and paper proposes review on approach...
