Feeding tube

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 how about the energy put…

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 this is: Total =…

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 minutes on ice, we removed the tubes,…

In these camps “the death rates were so high, from malnutrition, typhus and exhaustion that the disposal of corpses became a serious problem.” (THE CAMPS) The treatment in transporting and caring for the victims is probably one of the main factors in the dehumanization of people during Holocaust. The victims were treated inferior simply because of their nationality. The Nazi’s made it a point to degrade these people in every way possible by taking away their rights and free will.…

When we 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…

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…

My friends and I consider ourselves to be very spontaneous and adventurous. It was one cold week in February of 2016, when a group of about 6 of my friends (including me) all decided that we wanted to go to Vermont for the weekend to ski and snow tube. Considering this would be my first trip with no parental guidance at all, I was apprehensive about asking my mom. On the way to drop me off after school one day, my best friend Tony told me to tell her that he was going too so then she’d say yes…

Determination of Most Advantageous Sequestering Agent By: Kayla Jeeter and Ashley Driscoll Chemistry 112-508 Abstract The creation and execution of this project served to determine what material is a better sequestering agent of the polycyclic aromatic hydrocarbons (PAHs) that are found in Texas’ water. Charcoal is currently the most typical agent used to sequester PAHs. In this experiment, two different Bentonite clays (zeolites) were synthesized, one magnetized and one not, to determine if…

As an individual, I have always had this perception of wanting to make this world a better environment or at least a positive impact for people. This has directed me to the path of being in the medical field as a pediatrician for children. Many children may suffer from diseases or a type of illness in which they can not afford of seeing a pediatrician due to financial stability or economic reasons. In order to pursue this goal of mine, I have been immensely putting forth an effort towards…

Feeding America.org, Our History, tells about a man named John van Hengel, a retired businessman from Arizona, who got the idea of a food bank in the late 1960s from a mother who searched through grocery store dumpsters to feed her family. She suggested the…
