Manual Testing Faq’s What is software testing? Software testing is the process used to help identify the correctness‚ completeness‚ security‚ and quality of developed computer software. Testing involves operation of a system or application under controlled conditions and evaluating the results. Controlled conditions should include both normal and abnormal Why Management some times not serious about testing? Solving problems is a high-visibility process; preventing problems is low-visibility

The Distillation of an Unknown Compound INTRODUCTION Distillation is the process heating a liquid to form vapor which is then collected when cooled and separated from the original liquid. The purpose of this experiment was to determine the identity of an unknown substance using simple and fractional distillation. Gas chromatography analysis the components of a mixture by separation of the materials by their different boiling points. EXPERIMENTAL The simple distillation apparatus was assembled

Abstract In the asymmetric synthesis of (S)-Ibuprofen‚ the compound is synthesized in nonracemic form directly from an achiral precursor. First‚ racemic ibuprofen was converted to aN achiral ketene via the acid chloride by adding thionyl chloride followed by triethylamine. Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides
