In this experiment two solutions were prepared for two kinetic runs. Solution #1 (50%ethanol 50% water) and Solution #2 (40% ethanol and 60% water) was added to another Erlenmeyer flask. Next, 0.10M of NaOH was filled up to the 0.00ml mark in two 50-ml burettes. Placing the flask containing solution 1 on the magnetic stirrer and clamp a burette containing 0.10M of NaOH above the flask. The two kinetic runs will be carried out one after another. A stir bar was placed into the flask containing solution #1 and 3-5 drops of phenolphthalein indicator solution to the reaction flask. To start the reaction, 4.91x10^-3 mol of alkyl halide to the stirring reaction mixture. The timer was started at the instant of this reaction. When enough HCl formed to neutralize the NaOH that was initially added, the pink color turned clear. The time was recorded.…

As many of you may know, I have decided to leave the Atlanta Falcons Physical Therapy Centers in order to open my own practice, PT 360. I have two convenient locations; one in Johns Creek and the other is in Sandy Springs.…
The product was placed in a beaker, and enough aqueous methylated spirit (IMS) was added whilst the mixture was heated to dissolve the product. The mixture was then left to cool and was placed in ice to aid crystallization. The product was vacuum filtrated after a few minutes of standing in ice and the crystals were collected and dried in a vacuum oven at 40 degrees celsius. The mass of the crystals was calculated and the melting point was determined.…
The social wasp Polybia paulista protects itself against predators by producing venom known to contain a powerful cancer-fighting ingredient. A study published this month reveals exactly how the venom's toxin called MP1 (Polybia-MP1) selectively kills cancer cells without harming normal cells. MP1 interacts with lipids that are abnormally distributed on the surface of cancer cells, creating gaping holes that allow molecules crucial for cell function to leak out.…
1-1. HISTORY Military history reveals that armies throughout the world participated in some form of drill. The primary value of drill, historically, is to prepare troops for battle. For the most part, the drill procedures practiced are identical to the tactical maneuvers employed on the battlefield. Drill enables commanders to quickly move their forces from one point to another, mass their forces into a battle formation that affords maximum firepower, and maneuver those forces as the situation develops. a. In 1775, when this country was striving for independence and existence, the nation’s leaders were confronted with the problem of not only establishing a government but also of organizing an army that was already engaged in war. From the “shot heard around the world,” on 19 April 1775, until Valley Forge in 1778, Revolutionary forces were little more than a group of civilians fighting Indian-style against well-trained, highly disciplined British Redcoats. For three years, General George Washington’s troops had endured many hardships—lack of funds, rations, clothing, and equipment. In addition, they had suffered loss after loss to the superior British…
In a 250 ml Erlenmeyer flask, (+) tartaric acid (11.9 g) was dissolved in 165 ml of methanol. This mixture was heated on a steam bath. Racemic (+,-) α-phenylethylamine was slowly added to mix well.…
Administration (BCMA) in acute care and long-term care settings. Background: Medication errors are the most commonly documented cause of adverse events in hospital settings. Scanning of bar codes to verify patient and medication information may reduce medication errors. Method: A prospective ethnographic study was conducted using targeted observation. Fifteen acute care and 13 long-term care nurses were directly observed during medication administration at small, medium, and large Veterans Administration hospitals to detect workaround strategies. Results: Noncompliance with recommended practices was observed in all settings and facilities. A larger proportion of acute care nurses than long-term care nurses scanned bar-coded wristbands to identify…

I have been apart of the OPCraft community for a VERY long time. I'm just the type of person that never really wanted my self to be noticed within the community I just played the game and had fun. I stopped playing minecraft in general for a bit but I have decided that If I'm going to stay and play the game, I want to be apart of something and make my self and my skills useful within the community. I feel that I am perfectly fit for this rank because of my maturity and respect towards players on the server. I have an insane amount of patience and I think that may be one of the #1 things you need to become a staff member. I'm a very respectful person and I love to help people that are in need.…

While initially successful, the moment that President Johnson confiscated the land given to us, the Freedmen, under Sherman's Field Order 15, Reconstruction failed. This land should have remained the rightful property of the Freedmen as a gesture of concession, validity of African American rights, and just punishment to white planters.…
Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point.…
Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash. Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications. Most applications exploit its reactivity toward acids and its corrosive nature. In 2005, an estimated 700,000 to 800,000 tonnes were produced. Approximately 100 times more NaOH than KOH is produced annually. KOH is noteworthy as the precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals. Other names are Caustic Potash, Potash Lye, Potassia or Potassium Hydrate.…
