Intact Dilation and Extraction Intact dilation and extraction which is also known as intact dilation and evacuation‚ intrauterine cranial decompression and most commonly but controversially known as partial birth abortion has created ethical waves in medicine over the years. This specific procedure has been a primary focus of many politicians and religious groups although it only makes up approximately .08% of abortions‚ or approximately 1‚032 per year‚ based on research done in the year 2006

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion

of genomic DNA from animal tissues Introduction A rapid expansion of DNA analysis in medical‚ biotechnological and basic research has created the need for simple and efficient commercial methods for isolating genomic DNA. Many different methods and technologies are available for the isolation of genomic DNA. In general‚ all methods involve disruption and lysis of the starting material followed by the removal of proteins and other contaminants and finally recovery of the DNA. Removal of

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

DNA profiling DNA profiling (also called DNA testing‚ DNA typing‚ or genetic fingerprinting) is a technique employed by forensic scientists to assist in the identification of individuals on the basis of their respective DNA profiles. DNA profiles are encrypted sets of numbers that reflect a person’s DNA makeup‚ which can also be used as the person’s identifier. DNA profiling should not be confused with full genome sequencing. It is used in‚ for example‚ parental testing and rape investigation
