1. Shell and Tube Heat Exchanger – Working Principle The shell and tube heat exchanger comprises of two major things as its name state "Shell and Tube". The shell is a major vassel with quantities of tube inside it (Jalmood‚ n.d). Shell and tube heat exchangers are helpful for pressurized application. Heat is exchanged between the liquid in the tubes and the liquid inside the shell. Configuration of the tube pack is such that‚ all the section sides of the tube could be joined with a typical header

The singular deviation during this experiment was that we did not centrifuge the tube (for 5-10 seconds) after incubation. The mitochondrial DNA was amplified in sterile 0.5 ml PCR tubes. The reaction in tube one contained‚ 2 µl of our genomic DNA‚ 1 µl JOSH01 (a 10 µM forward primer) and 1 µl JOSH02 (a 10 µm reverse primer‚ 10 µl 5x Taq and 4 µl MgCl2. 1 µl of Taq polymerase and dNTP as well as 30 µl deionized water were added. For the second tube‚ 2 µl of JOSH04 (forward primer) and JOSH05

Experiment 1 Calorimetry Chem 17 Univerity of the Philippines Diliman Discussion All chemical reactions involve energy. By understanding the behavior and connection of energy flow within a chemical reaction‚ we can understand and manipulate them to our advantage. The most common form of energy observed during chemical reactions is heat. The reaction may absorb (endothermic) or release (exothermic) heat‚ depending on the reacting substances. Calorimetry is the process of measuring the heat flow

addressed in the modern day. Although many of us would agree not to commit crimes‚ Milgram’s experiment proves that humans are easily manipulated. At the beginning of the 1930’s‚ Adolf Hitler’s Nazi Party exploited the widespread discontent in Germany to attract popular and political support. Though the Germans were

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color

This would have messed up the experiment since you would have been measuring the activity of both potatoes instead of comparing the activities of the potatoes in different test tubes. I would have been incapable of measuring whether or not the enzyme peroxidase worked as well a regular after being soaked in ethanol since I would also be measuring the activity

known as the test tube baby. In Vitro Fertilization (IVF) is the most common among the high-tech fertility treatments. It can help the woman conceive if she has ovulatory problems‚ if they have problems in the fallopian tubes‚ if their partner has low sperm count‚ or other fertility treatments are unsuccessful. It is an assisted reproductive technology (ART) where in one or more eggs are fertilized not in uterus but outside of the female’s body. Its result is often called the “test tube baby”. There are

One flask was half-full of water and the other contained a pair of electrodes. The water was heated to evaporation (the oceans); sparks were fired between the electrodes (lightning) through the atmosphere and water vapour. It was then cooled again
