3.3. Characterization of the S2 VNP loaded liquid SNEDDS 3.3.1. Assessment of self-emulsification efficiency The emulsification time for S2‚ which is the time needed for SNEDDS to form homogeneous transparent mixture upon dilution‚ was 12 sec when 1 gm of VNP SNEDDS was added to 200 ml of 0.1 N HCl. When the same experiment was performed but by using 500 ml distilled water‚ the time required for the complete disappearance of SNEDDS was 14 sec. The emulsification in both media is under grade A of

water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor‚

useful for the simple identification of colourless organic liquids and ones that are often found at the scenes of crime. The first test carried out was the Lucas test which was used to identify a variety of alcohols following the contribution of a given solution‚ from carrying this out I could then identify that primary and secondary alcohols were present with one tertiary alcohol also being present however despite this given the colourless liquid that formed it is questionable as to whether the first

Acetone/Chloroform Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the standard

Last Chance Securities Situation: The IT director opened the department staff meeting today by saying “I’ve got some good news and some bad news. The good news is that management approved the pay- roll system project this morning. The new system will reduce clerical time and errors‚ improve morale in the payroll department‚ and avoid possible fines and penalties for noncompliance. The bad news is that the system must be installed by the end of December in order to meet new federal reporting rules

OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol Antiseptic Liquid is 4.8% chloroxylenol
