Sharpie permanent markers contain n-propanol (C3H8O) n-butanol (C4H10O), and Diacetone alcohol (C6H12O2). These markers are generally used on hard, non-porous surfaces, because instead of damaging the surface they form a surface layer that can be removed easily by solvents such as acetone (C3H6O), xylene (C8H10), or toluene (C7H8). Acetone (strong chemical used in nail polish remover) is a strong and very effective against permanent markers. It can also remove paint and melt certain surfaces.…

If you are looking for ways to reduce your energy bill this winter, you should look into insulating your electric water heater. An uninsulated water heater loses heat, which can impact your overall energy costs, especially during the winter months when it is colder. Here is what you need to do in order to insulate your electric water heater. #1 Clean Your Heater The first thing you need to do is remove any items that you have stored in or around your water heater. You'll want a clear work…

OVERVIEW Four ablations will be done in ex vivo bovine for each flow rate. There will be three different flow rates: 0 mL/min, 860 mL/min, and 1000 mL/min. These flow rate were chosen based on hepatic flow rates of humans in the supine position (Brown et al. 1989; Leen et al. 1992). Each ablation will be performed at 40 watts for 2 minutes for a total of 12 ablations. The average area of a 30ºC and 50 ºC contour at the end of the ablation will be used to characterize the size of the ablation…

The freezing point of the cyclohexanol was about 17.7°C, and the freezing point for the unknown solute mixed into the cyclohexanol was about 6.2°C. So the approximate change in temperature of the two freezing points was about 11.5°C. With this calculated information, the found molar mass of the unknown solute B was about 278.4g/mol, which is close to given molar mass of octadecanol. Conclusion- This lab allowed us to determine the molar mass of the unknown solute B by finding the difference in…

"Economic and environmental aspects of Fracking - Fracking is an economically beneficial and essential process for oil companies. Fracking is a process of drilling and injecting fluid into ground at a high pressure to fracture shale rocks to release Hydrocarbons, but it has raised certain environmental concerns that that have burdened oil companies to overlook at the processes they are using to extract hydrocarbons. Certain concerns about Fracking are: Hydraulic fracking is quenching the water…

Everyone knows the importance that drinking milk has on developing strong bones and muscles. There's another drink, however, that's even more important for a healthy body that doesn't get as much attention: water. Every part of the body needs water, including cells, skin and vital organs. Water must be continually replaced as it is lost through sweating, breathing. digestion and urination. Not replacing this necessary component of the body has serious consequences. As the video explains, the…

Fluid Management in CRRT The volume of hourly ultrafiltrate removed depends on an hourly fluid balance calculation and assessment of patient’s hemodynamic and fluid status. Hourly fluid goal calculation is the non-CRRT intake, plus fluid loss ordered by the physician, minus non-CRRT output. The system infuses and removes fluid after the fluid balance is calculated, and the desired volumes are input into the system. The system monitors the volume of replacement fluid, dialysate, and the volume of…

Tips For Replacing Your Vehicle’s Serpentine Belt While many drivers know that they need to do things like change their vehicle’s oil and air filters, some other parts of the car often are ignored. One part in particular that can wear down is the vehicle’s serpentine belt. If this part breaks while you’re driving, your car will be unable to run and you’ll need to have it repaired immediately. Thankfully, it’s easy to replace a serpentine belt when you notice wear to prevent this from happening.…

FRACKING Social medias and recent technologies like Facebook, Instagram, smartphones and Skype are typically known as one of the most important innovations during the 21st century. Although fracking is a very important innovation, it is not as commonly known topic in daily life. To simply describe the definition of fracking, it is a dangerous process of extracting natural gas from shale rock layers, deep within the earth. Injecting water, sand and chemicals into the rock at a high pressure, it…

The topic for the experiment is how a cold pack can be improved. The problem statement is “Which chemicals would work best at lowering the temperature of water to improve a cold pack?”. The Independent variables are the are three chemicals, ammonium chloride, sodium chloride, and calcium chloride, that will be added to the water. The dependent variable is the temperature of the water in degrees Fahrenheit after the chemicals are added. The constants are the 50 mL of water in each cup, the…
