That summer of 1793 was inexplicably hot and unbearable. Alongside with the stifling heat‚ the Philadelphia was made to face one more‚ even more‚ dangerous problem: yellow fever. Fourteen-year-old Matilda (Mattie) Cook lived above a coffeehouse in Philadelphia during the late 1700’s. She shared the home with Lucille‚ her widowed mother‚ Captain William Farnsworth Cook‚ her grandfather who was a retired sailor along-with King George‚ his parrot‚ in addition to Silas‚ her orange cat. Lucille wasn’t

Crimea-Congo Hemorrhagic Fever There are over a dozen viral hemorrhagic fevers‚ and they are all divided into several different families of viruses. Some have no treatments and carry high death tolls‚ whereas others are easily treated and death easily avoided. Marburg and Crimea-Congo Hemorrhagic Fever are similar deadly viral diseases; however‚ they also have many differences as well. A hemorrhagic fever is a group of viral infections by insects‚ arachnids or rodents. (“Hemorrhagic Fever”‚ 2009) Both

Philadelphia yellow fever epidemic originated on July of 1793 and was one of the most significant American diseases in history. Yellow fever is known to be a contagious disease and at times transpired in mild provinces. Even though the first eruptions commenced along the coast and central of South America. It is proclaimed that Western Africa was the place where this disease primarily affected the people living there and later on spread to other regions. Not only does yellow fever contaminate humans

hard at one point or another. Fever 1793 shows how Mattie and her family go through hard times. In the book Mattie is a teenage girl living with her mother‚ grandfather and a girl named Eliza who work in the coffee shop they own. Mattie faces some hard times when the fever strikes the town. Mattie is able to get through these hard times with the strength that she has gained overtime. Some people may say that the theme of Fever is family‚ or bravery. The real theme of Fever 1793 is perseverance and strength

Mountain Fever Rocky Mountain Spotted Fever is a disease that transmits through tick bites. It can be fatal without treatment. Anyone can get the disease but it usually does not affect younger children that tend to be inside as much. The ticks that carry the disease are mainly east of the Rocky Mountains. Rocky Mountain Spotted Fever or RMSF was first recognized by an Army physician in 1896. For a while‚ no one knew what caused the fever. Researchers eventually began to notice when tick season was

In the midst of the 1853 yellow fever epidemic‚ physician Samuel A. Cartwright published “Prevention of Yellow Fever” in the New Orleans Medical and Surgical Journal. After introducing the predominant theories of disease transmission‚ contagionism and non-contagionism‚ Cartwright characterizes these ideologies as groundless “relics of medieval science … not derived from nature or the observation of facts” (292). Cartwright notes that the contagionists’ emphasis on strict quarantines had historically

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Ebola virus disease (EVD; also Ebola hemorrhagic fever‚ or EHF)‚ or simply Ebola‚ is a disease of humans and other primates caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus as a fever‚ sore throat‚ muscle pain‚ and headaches. Then‚ vomiting‚ diarrhea and rash usually follow‚ along with decreased function of the liver and kidneys. At this time some people begin to bleed both internally and externally.[1] The disease has a high

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when
