Liquid-liquid extraction

Coliscan easygel nutrient broth was stored in the freezer. Around 24 hours prior to sampling, the broth was moved to the refrigerator to thaw. The sampling procedure follows the procedure stated in the Coliscan Easygel Instructions. When we were ready to begin sampling, the thawed broth was placed into a cooler. We started sampling at Cornerstone pond then move to the Wyoming site, then downtown Grand Rapids, then Plainfield, and then Versluis lake. The procedure for Cornerstone pond and…

Rebecca Black Ms. Kiersti Ford NSCI 115 5 October 2015 To Frack or Not to Frack Hydraulic fracturing is a process began being used in Kansas in 1947 and, through the years, has become a regular practice used to stimulate natural gas and oil flow to an area and increase its production. It has presented many opportunities and challenges over the years. And it has brought many social and ethical concerns to light. There are different methods used in hydraulic fracturing and involves quite a bit of…

Oil Change An oil change is one of the most important ways to keep your car in the best possible running condition. We will be going over, in depth, about the oil change procedure. Before you begin you need to acquire the right tools for the job. You will need a high quality product selected oil filter, a funnel, an oil pan or bucket, newspapers, rags, and oil cleaners. The new filter is for replacing the old one, the funnel to properly put the oil in the oil tank, the oil pan or bucket to…

Specific Purpose: Introduction: Cancer, environment destruction, according to my audience analysis, these are both big deals to most of you. Hydraulic fracturing not only slowly causes environmental destruction, but it can cause disease such as cancer and a wide range of respiratory diseases. Credibility: I have previously done some research on hydraulic fracturing, just learning what exactly it is and why it is used. Thesis: Hydraulic Fracturing is a very dirty way to obtain energy,…

Diecast vehicles are made when manufacturers pour molten metals into a steel mold. Afterwards, they get decorated with plastic, rubber, other metal and glass. Before you purchase a diecast vehicle, first decide if you want a modern or vintage Honda diecast. Collectors normally hunt for the vintage pieces while children like the modern diecast models. That, however, is not always the case, and sometimes people collect all forms of diecast models. The diecast vehicles made after 1970 were…

and a fast blast stain. The EcoRl restriction enzyme is the enzyme that was used in order to cut the DNA at specific sites into many separate fragments. A centrifuge is a machine that uses a rotating container inside it in order to force all of the liquids to the bottom of the test tubes within the container. A water bath is a heated bath of water which is usually set at a specific temperature that is used to heat up substances. The DNA loading dye was used in order to visually see the DNA…

The purpose of this lab was to determine how different solvents affect the solubility of sugar. In this experiment 2 grams of sugar was mixed into 50 ml of rubbing alcohol, water and vegetable oil. It was hypothesized that the rubbing alcohol would dissolve the sugar the best followed by the water, and the vegetable oil would fail to dissolve the sugar. It was found out that both the rubbing alcohol and the vegetable oil were not able to dissolve the sugar. The water however, was able to…

During my time at Electric Boat, I was one of two lead engineers assigned to refurbish a damaged chilled water pump on a nuclear submarine. Neither the requisite spare part nor a new pump was available and the vendor had quoted approximately $500,000 and 6 months for the replacement part. When the Navy had determined that the repair was beyond their capability, the pump was shipped to us. We developed the concept of machining out a small teardrop shape from the damaged impeller and pressing in…

Physics Experimental investigations Will heating honey speed up how it falls from a spoon? The speed of falling of honey from an object depends on its viscosity. Viscosity is a measure of how much a fluid resists movement of a mass through it. It is the internal friction of a substance that causes it to be thick, sticky and adhesive. Apparatus needed for this investigation is: Electronic balance 750 grams of honey (around 530 mL / 530 cm3) Thermometer Bunsen burner / other source of heat /…

I was able to identify all the liquids in our sludge but only about half of our solids mainly because we only started working at a good pace towards the very final days of sludge. We didn’t identify any gases because there wasn’t any in our sludge. We only had three liquids in our sludge. We were able to get at least 10 ML. of liquid A and Liquid B. We had about 6 ML. of liquid C but on day #18, Monday, May 20, all our our liquid C was gone. I’m not exactly sure what happened like if the test…
