Three test tubes where number 1-3, the first and second test tubes (#1,#2) where mark at 1cm and 5cm from the bottom of the test tube while test tube #3 was mark at 3cm and 7cm. Test tube #1 was filled up to the 1cm mark with distilled water and to 5cm with Hydrogen peroxide. The substance was swirl for 30 seconds and the height of the bubbles column where recorded. Test tube #2 was fill up to the 1cm mark with catalase and to the 5cm mark with hydrogen peroxide. The substance was swirl for 30 second and the height of the bubbles column where recorded.…
The resistors R1, R2, RD, and RS calculated in the Prelab section were used to connect the circuit as shown in Figure 8-5. A load resistance RL of 10kΩ was used. The values of VD, VG, VS were measured and recorded. 3. The voltage vout was measured using an oscilloscope and the voltage gain AVG-D = vout/vin was calculated.…
General procedure: One equivalent of spacer was coupled using 2.4 equivalents of inhibitor, 0.18 equivalents of copper sulfate, 0.36 equivalents of (+)-sodium-L-ascorbate, in a mixture of 10% H2O in DMF, 24 mL/mmol spacer. The mixture was placed in the microwave for 30 minutes at 80oC Pro6 Spacer (10) (30 mg, 0.036 mmol) and 18 (36 mg, 0.087 mmol) were dissolved in 778 µL DMF. Copper sulfate (1.62 mg, 0.006 mmol) and sodium-L- ascorbate (2.57 mg, 0.013 mmol) were dissolved in 86 µL H2O. The two solutions were combined in a microwave tube and put in the microwave for 30 minutes at 80oC. The solvent was evaporated under reduced pressure.…
On the way from solar cell to the solar module, the output efficiency decreases. For example when a multi-crystalline PV solar cells of 17.8% efficiency is used, the resulting efficiency of a module is around 15.9 to 16.3%. This decrease in efficiency is mainly because of three distinct losses listed below. 1. Optical losses generated by material reflectance and absorption 2.…
We built the RLC circuit as shown in Figure 1 using 10 nF Capacitor, 1 kOhm Resistor, and 1 mH Inductor . Connect the circuit to the Analog Discovery Module and open the Digilent Waveform Generator. Set the AWG to a sinusoidal wave, the amplitude to 3 V, and the frequency to 1 kHz. Then open up the oscilloscope and measure the peak-to-peak voltage at node CH2+ . Run AWG1 Make a table of the input (Ch1+) and output (Ch2+) voltages beginning with 20 kHz and increasing by 10 kHz to 100 kHz Open Network Analyzer and set values to:…
I chose to change the inclination to a 75-degree angle for the third lab assignment. If I were a bird researcher studying a population of birds and the earth began to shift to a 75-degree inclination, the biggest change would be a rise in temperature at the latitude marked with the white “X”. At the original 35-degree inclination, the average temps for early spring are mild and as the months continue into summer; the average daily temperatures do not go above what is described as mild and a half. If a gradual shift began towards a 75-degree inclination, you would begin to see a rise in the temperatures for this region. In the early spring, you might still find mild temperatures but as the spring progresses into summer, the temperatures…
The core objectives of this lab is to understand the concept of cell association of received power (Rx) and designing a modified network planning for an LTE services using multiple eNodeBs for an indoor premises (shopping complex). We are also going to compare the noise limited and interference limited systems along with its interference synchronization in radio access network. To accomplish these objectives, we are going to perform the following tasks: 1. To expand the indoor design of LTE service for the shopping complex, we are going to use seven femtocell and will perform the SINR (signal-to-interference-plus-noise ratio) and bit-rate using the simulation tool Wireless Insite and MATLAB for coding.…

Objective Review: 1. Describe the purpose for using aseptic technique in collecting specimens Aseptic technique is used to prevent contamination of specimens by pathogenic organisms. The goal of maintaining asepsis is to not introduce any other organisms to the patient and prevent the spread of any organisms the patient may be carrying. Certain practices are used to help decrease this from occurring including cleaning, sanitizing, and disinfecting. Aseptic technique is an important process to prevent the spread of infection and diseases in the clinical setting (Hauswirth & Sherk).…
1. Goal The main purpose of this lab is to introduce us to the RLES vCloud system, begin setting up a network with a router VM and a main Redhat VM, and configure some baseline features for the continuation of our work in future labs. This included configuring DNS forwarding and NTP on the PFSense router VM, and configuring a wiki on the redhat VM alongside monitoring software such as Zabbix or Opsview. When configuring the router, all was fairly straightforward and without any major setbacks. The web panel was very helpful in configuring the various NAT, DNS, and NTP settings.…
In a day to day situation, if we want to find how much time does it take a person to go from Point A to Point B, we can use the equation T= D/V. In this equation, D represents the distances in meters between Point A and Point B, and V represents the speed (meter/ second) of how fast a person walks. In mathematical terms, it uses the total distance traveled to divided by the time to get an estimation of the average speed(second). But, if we want to find out the age of the universe ? Then, we need to take it into the universe’s perspective.…
Some of the similarities that I saw in the data are: 1. An increase in temperatures began in January and ended in July. After July, the temperatures decreased. 2. With the data I worked with, I noticed that the median tends to be around 50 to 60 degrees.…
In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…
Purpose: The overall goal of this lab was to perform a procedure on E. Coli which involved transferring genes that encoded for the green fluorescent protein into E. Coli to see if the transferred genes would make a difference on the growth and whether or not the bacteria would glow under UV light. Hypothesis: If the bacteria with the pGLO plasmid was grown on a plate containing LB and ampicillin then the bacteria will grow but not glow under UV light. If the bacteria with the pGLO plasmid was grown on a plate containing LB, ampicillin, and arabinose then it will be able to grow and glow under UV light. If the bacteria without pGLO plasmid was grown on a plate containing LB and ampicillin then it will not be able to grow or glow under UV light.…
