In "The Checklist Manifesto" Gawande started his introduction with a small story that has a deep core lesson. A guy came into the ER on Halloween night had a stab wound. At first‚ he seemed stable but drunk‚ and he was not rushed to the operating room because they believed it is not a bad injury. After a while‚ he suddenly collapsed and rushed to the OR. The surgical team discovered that the stab wound was very critical. It went too far through his skin and punctured his muscle‚ intestine and all

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

Compound Light Microscope The familiar compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes

Compound 50‚ like its known analogue 3‚ involves an α‚β-unsaturated ketone‚ an acid-sensitive reactant‚ which prevents its direct synthesis in presence of protic solvents by refluxing. Despite of this characteristic‚ 50 was formed smoothly in 5 minutes by grinding chemistry‚ solely as E-isomer‚ without any evidence of decomposition after 1H and 13C MNR analysis. This synthetic approach provides easy access to such α‚β-unsaturated N-acylhydrazones‚ which are building blocks in the synthesis of nitrogen-containing

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or

Comparison between Organic and Inorganic Compounds Organic Compounds | Inorganic Compounds | *Organic Compounds are composed of few elements only.C‚ H‚O‚N‚S‚P and halogens are the most common. | * Inorganic Compounds are composed of all the known elements. | *They are generally found in living matter‚ i.e.‚ animals and plants. | *They are generally obtained from non-living matter‚ i.e.‚ minerals. | *They are usually gases‚ liquids or solids having low melting points. | *They are usually solids

Covalent Compound: Cocaine Cocaine‚ also known as coke‚ is a covalent compound‚ which are molecules that consist of groups of atoms held together by covalent or coordinate bonds. In the United States cocaine is an illegal drug because of the harm it does to a human’s body. It has been used for many years for many different reasons by many different people. Cocaine and it’s leaves‚ which are found on the plant of the Erythroxylen coca (cocaine.org)‚ originated by the South American Indians who have

Identifying Organic Compounds 2. Purpose/Problem: I am doing this experiment to find out what kind of organic compounds are in test tubes A‚ B‚ C and D. I am curious to know if substance D was the lipid because it seemed thin and had a slightly yellow tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one
