The Tubes

All the general documents outlined activities and processes relating to the tube placement phase with 69.23% identifying that children would need to have an assessment by a medical officer and/or dietitian prior to tube insertion. Mode of delivery of enteral feeding and route selection information was outlined in 61.54% of the documents. Tube selection procedures (including sizing) was mentioned in 76.92% of the documents and insertion procedures and how to check positioning was outlined in 84.62% of the policies and guidelines. Many of the documents then provided information on choosing administration routes of feeds (i.e., continuous, bolus) (61.54%) and on formula selection (84.62%). Only one document from an Australian hospital mentioned blenderized tube feeds but stressed that the health service did not support the use these…

dialysis tubing was used to mimic the selectively permeable membrane to show what osmosis does when placed in different solutes. We filled dialysis tubes fill with different percentages of solute and placed them in beakers full of a different solute. Through this experiment, I saw what happens when the solution becomes hypertonic, hypotonic, and isotonic. My hypothesis was that bag A would shrink because the water would leave the bag to go to the higher concentration. Bag B would stay the…

Introduction This case study report is to outline the process of planning an activity in science understanding physical science for a 5 year old child with the expectation of learning the concept of motion, inertia, force, velocity, acceleration and gravity by using balls, blocks and tubes. The report will also outline the pedagogy approach adopted by educators to ascertain that the child will engage in a physical science activity, which will improve the child’s skills of problem solving,…

I chose to do my project on the Pyro board which is an adaptation of the Rubens tube. The Pyro board uses fire to demonstrate sound waves. I chose this as my project because I find music and fire fascinating. Having them interact to demonstrate the physics side of sound helped me understand all the different aspects that can effect sound waves and alter the way we interpret them. Before I started to build my Pyro board I did research on how they worked why they worked and why the flames reacted…

transformation solution to into two separate tubes. Next, we used a sterile loop to transfer two to four larger bacteria colonies from an E.coli plate into each of the two tubes. The bacteria was observed under UV light to make initial observations. We pipetted 10 ul of pGLO plasmid (0.08 ug/ul) into one of the tubes. Both tubes were incubated on ice for ten minutes. After ten minutes of incubation, the tubes were heat shocked at 42°C for exactly 50 seconds and then returned to ice. After two…

There seemed to be an error in the experiment conducted, which will be later discussed. In order to show what should have happened, the absolute value was taken of the answers using the numbers that were read from the spectrophotometer. For example, in the PTU test tube the amount after ten minutes subtracted from the amount after twenty minutes gave the answer of -0.023, but instead, and instructed by our teacher, we took the absolute value and said it was 0.023. The formula used to display…

Personal Energy and Material of Toothpaste The cycle of energy that gets put into the simple product of a tube of toothpaste is a rather lengthy one. Most people simply think of the raw materials that are put into the toothpaste, but what about the tube itself? Most people just consider the resources that are put into the paste, but what about the energy used to transport those resources or to mix them together. Perhaps one has considered the tube and the energy that was put into making it, but…

Figure 3, Affinity Column: Protein Concentration and Enzyme Activity, shows the two peaks for protein concentrations on the red line. The blue line, showing the enzymes activity, overlaps with test tube six that contained the active trypsin. The lack of overlap over test tube one combined with a peak for a protein concentration identifies the inactive trypsin. Using the equation in the sample calculation of trypsin percentage, it was found that there was 75.6% yield of trypsin. Future labs…

finally arrived at the water’s edge my brother John and I were so excited, we basically leapt out of the car before it came to a complete stop. Larry and my uncles unloaded the cars, while my Aunt Janet and Sister Lorena went to pick up the tubes. John and I decided to jump in the water to cool off while everybody else got everything ready for the trip down the river. We were all laughing and smiling all the while oblivious to the impending tragedy that lies ahead. The moment I jumped into that…

to a gentle boil, the sodium silicate solution was slowly added into the sodium aluminate solution, using beaker tongs to handle the hot beaker. The solution was then continuously stirred and kept at 90° C for 60 minutes. After 60 minutes, 0.7844g of and 0.3985g of were added to the solution. The solution was stirred until the iron compounds dissolved completely. Next, the heat was turned off and the solution was allowed to cool for 5 minutes. Equal amounts of the solution were then put into…
