Pour out 10mL of vinegar into the film canister, it should fill up about one fourth of the canister.

1. Take a few drops of water and place it an inch or so from each end of the glass slide.

You should microwave the solution until fizzing begins. Once heated, take a pair of tweezers to place the small parts from the Parkerizing pile into the glass container and let it blacken. The solution will cause fizzing on the weapon parts. After the Parkerizing process is complete, take tweezers and remove the weapon parts from the solution.

Obtain a watch glass. Take the filter paper out of the final and placed in the center of the watch glass. Make sure not to tear the filter paper or to lose any of the solid.

A stand was created using mala to support the slide so that it stood vertically. A thin layer of super glue was spread over the upper edge of the slide and left for a few seconds to dry in order to prevent the hairs from sliding. The thickest part of the shield was placed straight on the glue perpendicular to the slide using a tweezers. Approximately five to six hairs were placed side by side on each slide. The hairs were left on the glue over night to ensure that they had set properly.

Firmly grab the sides of the filter and gently squeeze the collected residue from the pond water, so that you can add a drop of the water from the residue to a clean glass slide. Carefully apply a cover slip to the slide.

Solar energy is the largest energy resource available on earth. Not to mention concern about climate change have made this resource prevalent to individuals looking to lower their carbon footprint. Installing solar panels can decrease a household’s carbon footprint by an average of 35,180 pounds of carbon dioxide per year (Tusher, Christine, 2014). Solar panels got their start in the 1950s. They are what produce solar electricity by using photovoltaic (PV) cells, meaning they are batteries that harness sunlight, transform it into energy, then send the energy to an inverter, which in turn converts the energy into electricity. A well-known example of an object that uses solar panels to power itself is a solar-powered calculator. One advantage

Place the other glass slide on top of the first, and gently pull the slides apart − dispensing the material on the slides evenly.

ligroin or hexanes to the top of the glass column. Add about 8 mL hexanes to the

3. Attach the stopcock to the tip of the titrator by placing the larger, clear, plastic end of the stopcock into the tip of the titrator and then twisting the stopcock into place. The stopcock should fit tightly into the titrator, so that the liquid will not leak.

3) put the slide you’re on your mechanical stage and make an adjustment to properly view your slides.

Using a capillary tube, one end was dipped in the sample solution to allow the solution to enter by capillary action. On one end, using the index finger block the top-end of the capillary, lightly and then quickly spot it to the mark on the TLC plastic sheet. Using new capillary tubes, repeat the same process for the other spots for all.

repeat step 3 6. Move microscope aside and add Oil immersion, leave for a few

In this report I will be investigating into photovoltaic cells, also known as solar cells, and “solar battery” (in early days). I will look at the purpose of them, the technologies in which they are being used, how they work and how they are used based on the actual examples. The other parts of the report will show the example of how they are used in the existing building and what function they have in it. I will also be looking at the advantages and disadvantages of using photovoltaic cell technologies and compare it to alternative technologies available on market that can be used, taking in consideration the aspects of both technologies. At the end of the report I will also look at the sustainable issues as well as the cost issues that come along with using this method in small and large buildings. I will look forward to generally summarize the use of photovoltaic cells and their aspects within the buildings.

A Solar Home System (SHS) is a type of PV system, typically a small standalone solar electrical system with a solar panel, a charge controller/regulator, a battery, and belt-in load applicability for simple, low powered electrical appliances such as lights, small radio, mobile phone charger, portable DVD player and a small TV. Its basic function is to utilize the sun’s energy to provide electricity for various electrical applications in a household.
