The main issue in working with fresh concrete is the workability during filling of formwork. One of the problems found in workability is occurence of segregation depending on w/c ratio. Segregation is strongly related to w/c ratio. The fresh concrete is usually considered as a non-Newtonian fluid since it is a mixture of aggregate, cement and water. The flow behaviour of the fresh concrete, a c...

BACKGROUND Delivery of drug admixtures by intravenous patient-controlled analgesia is a common practice for the management of postoperative pain; however, analytical confirmation of the compatibility and stability of butorphanol tartrate, ketamine hydrochloride, and droperidol combined in ternary admixtures is not available. METHODS Butorphanol tartrate, ketamine hydrochloride, and droperidol...

BACKGROUND Medications are frequently combined in the nebulizer cup, so it is important to determine their chemical and physical compatibility. OBJECTIVE To determine the chemical and physical compatibility of levalbuterol with ipratropium bromide, cromolyn sodium, acetylcysteine sodium, and budesonide. METHODS We mixed one dose of levalbuterol inhalation solution concentrate (1.25 mg/0.5 m...

In this study, it is aimed that production of high performance concrete using admixtures. The admixture is used to resist against to freezing of concrete, and concrete (C20) is produced, and cured in water. 8 samples are tested in pressure, and mean stress is determined as 28 MPa. Remaining two samples are tested with image processing technique, and determined that sample which containing an ad...

We calculate the electromagnetic moments and radii of the ∆(1232) in the nonrelativistic quark model, including two-body exchange currents. We show that two-body exchange currents lead to nonvanishing ∆ and N → ∆ transition quadrupole moments even if the wave functions have no D-state admixture. The usual explanation based on the single-quark transition model involves D-state admixtures but no ...

By combining the information from 19F, 1H-HOESY and PGSE NMR methodologies, unprecedented direct evidence has been obtained for the formation of supramolecular assemblies in solution between the trinuclear cyclic AuI basic compounds ([Au(mu-C2,N3-bzim)]3 (bzim = 1-benzylimidazolate), 1, and [Au(mu-C,N-C(OEt)=N-p-C6H4-CH3)]3, 2, on one hand, and the trinuclear cyclic HgII acid complex [Hg(mu-C,C...

We discuss the implications of partial dynamical SU(3) symmetry (PDS) for the structure of the lowest K=0 + (K = 0 2) collective excitation in deformed nuclei. We consider an interacting boson model Hamiltonian whose ground and γ bands have good SU(3) symmetry while the K = 0 2 band is mixed. It is shown that the double-phonon components in the K = 0 2 wave function arise from SU(3) admixtures ...

Fish oil-based emulsion is increasingly used in pediatric patients receiving Parenteral Nutrition (PN). However, its unique use in children on long-term PN is nutritionally debatable as some patients are better off with a mixture of long-chain (LCT) or long-chain + medium-chain (LCT + MCT) triglycerides along with Fish Oil (FO). Lipid emulsions are safely infused when particle diameter ranges b...

Purpose The physical stability of two types of total parenteral nutrient (TPN) admixtures was studied as a function of storage time and temperature. One of them contained only structured triglycerides and the other exclusively long-chain triglycerides as lipid components. Methods Droplet size of the mixtures was followed by photon correlation spectroscopy for 10 days. Zeta potential and dynamic...
