The Effect of Common Household Drugs on Circulatory Function free essay sample

An experiment was conducted to observe the affects of household drugs on pulsation rate. Since pulsation rate is such a simple physiological system it will be easier to observe a change. Lumbriculus variegatus (blackworms) were used to observe there pulsation rate. Blackworms were used do to absence of a respiratory system; they also rely on diffusion for gas exchange. Blackworms don’t have a heart there vessels are what moves the blood back in forward. Each open and closing is a pulse. In the first part of the experiment concentration of drugs were used (caffeine and nicotine). The nicotine and caffeine solution will have an affect on pulsation rate.

As seen in part one of the experiment it was concluded that similar result would be found. The extract will have no real significant affect on the blackworms pulsation rate.

Cryptid

Cryptid Cryptid Cryptid By Maeve Maddox The lovely word cryptid came to my attention in reference to the ivory-billed woodpecker. One of these birds, long believed to be extinct, was sighted in eastern Arkansas in 2004. As no subsequent sightings have been reported, the survival of the species is still disputed. Cryptid is of recent coinage, suggested in 1983 by J. E. Wall in a publication of the International Society of Cryptozoology, as a word â€Å"to replace sensational and often misleading terms like monster.† Note: The Google Ngram Viewer shows use of cryptid as early as 1963, but the appearance in the ISC newsletter is most likely the cause of the word’s meteoric rise from 1990 to the present. Cryptozoology may be a pseudoscience, but the word cryptid is a useful addition to the English vocabulary, joining other English words that derive from Greek kryptos, â€Å"hidden†: crypt (1583) An underground cell, chamber, or vault; especially, one used as a burial place and typically lying beneath a church. cryptogram (1827) A piece of cryptographic writing; anything written in code or cipher. cryptology (1844) The science, study, or practice of encrypting and decrypting information. cryptonym (1862)   A pseudonym or code name; esp. one given to a spy or to a clandestine operation. crypsis (1956) Cryptic coloration or behavior that enables an animal to conceal its presence. Cryptozoology (1968) The study of unknown, legendary, or extinct animals whose existence or survival to the present day is disputed or unsubstantiated. Cryptids more sensational than the ivory-billed woodpecker include the following: Abominable Snowman Big Foot chupacabra Fouke Monster Kelpie Water horse Loch Ness monster Mermaids Sea serpents Sewer alligators For a lengthy list of cryptids, see the Wikipedia article.

Google - Essay Example This increase between the offer price and the open price is much greater than the increase for typical IPOs in 2004. Indeed, 82 percent of the IPOs issued in 2004 experienced less of a jump from the offer price to the open price than Google did, and the statistics were similar for IPOs issued prior to Google's debut and following Google's debut. The enormous post-auction price increase of Google, especially in the immediate weeks and months following its debut, when there were few substantive news releases on changes in company strategy and fundamentals, further suggests that the online auction method may not have priced Google efficiently. Google subsequently soared in the following months to a high of $317.80 on July 21, 2005. As of June 29, 2005, Google had exhibited price appreciation of 186.8 percent, relative to its open price. Critics of Google's IPO initially argued that the auction was a failure because Google slashed the number of shares that it would sell at public auction from 25.7 million to 19.6 million shares. Also, it dropped the target price range from the $108-to-$135 range projected in late July to the $85-to-$95 price range (Knight Ridder, August 19, 2004). At the time, many analysts suggested that the earlier Google price range had been overpriced; yet, Google's closing price reached the lower end of that price range after 18 days of trading and reached the higher end of that price range after 32 days of trading. The lessening interest in Google at the time that it reduced the price range during the summer was possibly due to some combination of the following factors: - The lack of information provided by the company during the process about its uses of capital - A slump in price appreciation for June IPOs - Reservations on the part of investors about the use of the online process. Who benefited from Google's price appreciation Under the traditional process, the preferred clients of the underwriting investment banks can benefit from the initial IPO underpricing and subsequent price appreciation since they have the initial allocations. In the case of Google, the beneficiaries in the price appreciation have been: 1. those investors who bought Google when it first began trading and held it until the price increased substantially and 2. the Google co-founders and the chief executive, as well as the venture capital firm involved in financing Google, who were allocated shares early in the process, but who could not sell them until the "lock-up period" expired. "Google announced in its IPO prospectus that it wouldn't provide traditional earnings guidance. While it took this stance to avoid short-term thinking, the move also likely left Google's directors knowing more about company prospects than other investors. The third quarter, which Google was in at the time, proved to be one of spectacular growth." (Delaney, September 2005) By July 2005, the CEO Eric Schmidt and the company founders Sergey Brin and Larry Page had sold $1.7 billion in stock, other executives had sold more than $800 million in stock, and no open market purchases had been recorded. Indeed, Page and Brin have sold 3.7 million and 3.8 million shares, respectively, or roughly 400,000 shares per month, while Schmidt had sold 1.3 million
