PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

F1-F4: Emulsion Solvent Diffusion Method (ESD) The microparticles of formulations from F1-F4 which are prepared by ESD method were irregularly spherical in shape. The percentage yield increased with increase in polymer concentration from 88.3 to 93.6%. Stirring speed does not show any valid effect in the percentage of yield. Particle size increased with increase in the polymer concentration due to the viscosity character of the polymer which comes in contact with the drug to form microparticles

Where could I be? The last time‚ I remember it was morning and I was swimming and now it is afternoon and I am somewhere. I guess I drowned and landed up here. I am surrounded by many people and they all look different from my country people. Men are fierce looking and wearing woolen undershirt and leggings under a belted tunic and coat. Women are wearing long linen shift under woolen tunic‚ clipped at the shoulders by two brooches. All were wearing woolen and fur hats‚ socks‚ soft leather shoes

Investigation the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to

Q-1 A surgeon wish to predict the live or death (status) of a CABG patient through their pulse rate‚ systolic blood pressure‚ sugar level‚ hemoglobin etc. He got the data from last 1600 surgeries held in a local hospital and applied an analysis. He got the following result Identification: It is binary logistic regression (LOIGT) Coding 0 = Death 1 = Alive The two post-operative status of the patients are death and alive coded by 0 and 1 respectively to use in binary logistic regression.
