The drag-reducing effects of two nonionic-type surfactants, oleyl-N, N-dimethylamine N-oxide (ODMAO) and octadecyl-N, N-bis(2-hydroxyethyl)amine (C18BAO), in ethylene glycol (EG) aqueous solution were comprehensively investigated at various surfactant concentrations up to 2000 ppm by weight temperatures ranging from −5 80 °C turbulent pipe flows. In EG (30% weight), the mixture ODMAO with salic...

    Topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. The new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. The adhesive capacity of hydroxypropyl methylcellulose (HPMC) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling test...

Lysophosphatidic acid (LPA) is a lipid mediator that is known to exhibit chemotactic activity toward a variety of cancer cells. However, its effect on the immune system has not been studied extensively. Another lipid mediator, sphingosine-1-phosphate (S1P), has been shown to influence lymphocyte recirculation by regulating lymphocyte egress from lymphoid organs. In this study, we found that LPA...

Nanoscaled VO2 structures were made using a fast microwave-assisted synthesis method in acetophenone as solvent, starting from vanadium pentoxide V2O5. Insights the reaction and purification process elaborated by attenuated total reflection infrared nuclear magnetic resonance spectroscopy, which validated choice of oleyl amine ligand solvent. A straightforward heat treatment inert atmosphere wa...

addiction to drugs, such as heroin, cocaine and alcohol, exacts great human and financial costs on society. various evidence-based pharmacological and psychosocial interventions are currently used in the treatment of drug addiction but they do not produce adequate therapeutic benefits in every patient. further, barriers such as financial cost, lack of availability, or perceptions of existing tr...
