BACKGROUND The start-up behavior of syringe and syringe pump is known to be one of the causes of inaccurate intravenous infusion. This study evaluated the method of priming the infusion system (PRIMING), and its impact on the target-controlled infusion (TCI) of two remifentanil diluents. METHODS PRIMING was performed using an evacuation of 2.0 ml to the atmosphere prior to TCI. Forty-eight TC...

The fact that the choice of organic diluent is important for a solvent extraction process goes without saying. Several factors, such as e.g. price, flash point, viscosity, polarity etc. each have their place in the planning of a solvent extraction system. This high number of variables makes the lack of compilations concerning diluent effects to an interesting topic. Often the interest for the r...

This work studies the solvent extraction of lithium ions from alkaline aqueous solutions by chelating agent 3-benzoyl-1,1,1-trifluoroacetone (HBTA). To develop a more eco-friendly system for than currently used, various hydrophobic room-temperature ionic liquids were investigated as diluents. The influence several experimental parameters on was examined, including phase pH, nature counter-ion, ...

Bottom-up synthesis of cubosomes is more energetically favourable than top-down approaches. However, bottom-up methods often rely on organic solvents such as ethanol diluents, and lead to concurrent formation liposomes. We propose using non-toxic diluents honey, glycerol lactic acid for cubosome synthesis. Cubosomes were prepared solutions phytantriol in a range including choline chloride-glyce...

Presented here is an investigation into the glassy state molecular mobility of modified epoxy amine networks using sub-ambient β relaxations measured from dynamic mechanical and their relationship to compressive properties. Two classes additives are used modify network, first bulky inorganic siloxane caged functional polysilsesquioxanes (POSS) second mono-functional diluents. Different pre-reac...

This study was performed to evaluate the effectiveness of three different conditions of osmotic pressure (325, 365 and 385 mOsm kg-1) in combination with dimethyl sulfoxide (DMSO) and NaCl or glucose on spermatozoa DNA damage, rate and duration of motility. Sperm was collected from eight healthy mature Mesopotamian catfish, evaluated microscopically and pooled at 25 °C. The pooled sperm samples...

The objective of this study was to test the effect of four different diluents on the motility of goat semen stored at room and refrigerator temperatures. To achieve this objective, four West African dwarf bucks aged 10-12 months were ejaculated weekly for five weeks using the electro-ejaculator method. The ejaculated semen were extended using four diluents namely sodium citrate (T1), sodium bic...

The adsorption of the proteins CD13, mucin and bovine serum albumin on VLGXE-Au and YNGRT-Au interfaces was monitored by electrochemical impedance spectroscopy in the presence of [Fe(CN)6](3-/4-). The hydrophobicity of the Au surface was tailored using specific peptides, blocking agents and diluents. The combination of blocking agents (ethanolamine or n-butylamine) and diluents (hexanethiol or ...

A comparison of spermatozoa from intact boars and from boars without seminal vesicles, frozen in various diluents, was made to determine any differences in sperm quality after thawing and the conception rates of gilts. Sperm samples were frozen at -196 degrees C. 50 semen pellets were thawed after 1-3 weeks storage and assessed for postthaw motility at 37 degrees C. The percentage of eosinop...

This study examines the sustained release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water-insoluble (indomethacin) drugs from Leucaena leucocephala seed Gum isolated from Leucaena leucocephala kernel powder. It further investigates the effect of incorporation of diluents like microcrystalline cellulose and lactose on release of caffeine and pa...
