Within the first two years MEDACE had built a nuclear reactor, underground waste storage tanks and a nuclear fabrication facility. All the facilities were in operation to develop plutonium fuels for military defense (Gephart and Lundgren 1998). The site was in operation for 44 years and was decommissioned in 1987 (Wald, 1998). During this period, approximately 110,000 tons of nuclear fuel were processed at Hanford Site (Wald, 1998; Gephart and Lundgren 1998). It produced 73 tons of nuclear weapons and reactor fuel-grade plutonium during the time of its operations (Gephart and Lundgren 1998). The production of nuclear weapons and nuclear fuels generated huge quantities of highly radioactive waste which was stored in underground storage tanks. Most liquids from single-shell tanks have been pumped to the newer double shelled tank over the years, to remove the remaining 9000 cubic meter of drainable liquid (Hanlon 2003). Salt cake and thick waste sludge was left behind in the tank. No double shell tank has leakages till date, even though the design life of oldest ones has been reached (Hanlon 2003). However majority of single shelled tank exhibited some kind of leakages ultimately contaminating the site. The U.S Department of Energy (DOE) currently manages the site and is responsible for cleaning

Accumulated Change vs. Definite Integral Free Essays

Martyna Wiacek MTH 116 C- Applied Calculus 11/6/2012 Chapter 5 Writing Assignment There is a correlation between area, accumulated change, and the definite integral that we have focused on throughout Chapter 5 in Applied Calculus. When looking at one rate-of-change function, the accumulated change over an interval and the definite integral are equivalent, their values could be positive, negative or zero. However, the area could never be negative because area is always positive by definition. We will write a custom essay sample on Accumulated Change vs. Definite Integral or any similar topic only for you Order Now The accumulated change looks at the whole area of the function that is between the graph and the horizontal axis. For instance, if f (x) is a rate-of-change function the area between f (x) and the x-axis represents the accumulated change between x = a and x = b. However, the definite integral puts specific limits into the function and the area of a particular region can be determined. For example, if f (x) is a rate-of-change function it means that: is what you can consider the area. The accumulation of change in a certain function can be evaluated by using the area of the region between the rate-of-change curve and the horizontal axis. We also see a similar relationship between the rate-of-change graph and the accumulated graph that we saw in derivatives. A minimum in the accumulated graph is caused by the rate-of-change function crossing over from positive to negative. A maximum in the accumulated graph is a result of the rate-of-change function moving from negative to positive. When there is a maximum or minimum in the rate-of-change graph you get an inflection point in the accumulation graph as well. Also, we see that if the rate-of-change function is negative then the accumulated graph is negative and so the accumulation graph is decreasing. However, when the rate-of-change graph is increasing, it does not affect whether or not the accumulated graph is increasing or decreasing. There are several problems in our book that demonstrate this relationship. A specific example that I believe did a good job demonstrating it was: The graph in the figure represents the rate of change of rainfall in Florida during a severe thunderstorm t hours after the rain began falling: Part A: Use a grid to count boxes and estimate the accumulated area from 1 to x for values of x spaced 1 hour apart, starting at 0 and ending at 6. Record the estimates in a table. 0| 0| 1| . 4| 2| . 65| 3| 1| 4| 1. 35| 5| 2| 6| 2. 4| Part B: Sketch the graph of the accumulation function based on the table values: Part C: Write the mathematical notation for the function sketched in part b: Part D: Write a sentence of interpretation for the accumulation form 0 to 6 hours: After 6 hours of rainfall in Florida, the amount of rain should accumulate to an estimate of 2. 4 inches.

Rooms Division Management

Question: Discuss about the Rooms Division Management. Answer: Introduction: I share the writers views on the importance of the topics from a Rooms Division Management perspective. What makes a person hospitable? Just a few people are born with natural skills to be genuinely hospitable. Lots of us ought to examine the artwork of hospitality.

International resort chains are expanding their commercial enterprise all around the globe; consequently, such resorts require staffs that understand other languages. They need to also be capable of communicating in foreign languages and correlate with colleagues with various cultural backgrounds. Even hoteliers who in no way left their personal motherland must deal with global guests and employees belonging to distinct nationalities and cultures (Giancarlo, 2010). That way they reach out to diverse clientele and consequently increase room reservations. Online Travel Agencies (OTAs) as Expedia and Booking.com are dependable for an extensive extent of online hotel room reservations, however, all together, request for 9-16% in commission fees. Free hotels are especially OTA-subordinate by and large, more than 50% of autonomous hotel rooms are reserved online however sadly, just 24% of these bookings come by means of the hotel website, while 76% percent are made through OTAs. An all around connection with an OTA can be gainful however; reliance is dangerous and vigorously wound up in a real predicament line. OTAs are able to drive direct bookings! OTAs are mainstream for starting research as indicated by Tripadvisor, 57% of individuals surveyed overall used an OTA to arrange their travel. Yet, this does not need to mean booking through them as well. Google observes that 52% of travelers visit a hotel website in the wake of seeing it through an OTA. This is the ideal time to start engagement. It is advisable to use OTAs to construct awareness and the image, however a hotel should ensure to do the best to guarantee that once potential customers arrive on the website, they stay there to book (Google, 2016; Abraham Judy, 2010). Other factors to consider The authors should consider other factors in trying to generate direct reservations and thus increasea occupancy, ADR and revPAR. The Rooms department includes sub-departments, Housework and the Front Office. Earlier on, housework was considered only a cleansing department; however, hotel surveys have shown repeatedly that cleanliness is on the pinnacle of the listing of necessities of resort guests. Therefore, this commentary deals with cutting-edge control techniques to increase direct reservations and equipment utilized by housekeeping managers to ensure a safe and comfortable stay for guests. The operations of a Front Office are the heart of a resort (James, 2010).

Right here are factors at the hub to look for to find robust revenue for a hotel: Aggressive: a passion to win; constantly striving to develop the commercial enterprise Collaborative: the ability to talk well at all degrees of company Analytical: records drive selections; the ability to research records and become aware of possibilities to enhance Supply and demand: understanding of micro and macro economic factors that affect a business Internet expertise: the net touches every issue of the hospitality; knowing how to leverage its really an essential commercial enterprise want Business Acumen: all of it comes back in a hotel; analyzing monetary statements and being capable of interpreting financial statements to make appropriate commercial enterprise decisions.
