1789

April 30, 1789 George Washington becomes the first president

1791-1794

The Whiskey Rebellion was a tax protest in the United States under the president George Washington. The so-called "whiskey tax" was the first tax imposed on a domestic product by the newly formed federal government to generate revenue for the war debt incurred during the Revolutionary War. The events led to the formation of political parties in the United States, a process already underway. In the early 1800s, whiskey tax was revoked during the administration of Jefferson.

Section cinco: Sinusitis and Epilepsy

Sinusitis

8) c) Chronic Sinsusitis, which lasts more than 12
 d) Recurrent Sinsusitis, with several attacks within a year 

9) Symptoms Huge pain which may be localized to the sinus or generalized pain which may present as headache and lots of mucus will be generated, Patients can also have fever 

10) Treatment: X rays / CT scan can be done to visualize sinuses. Nasal decongestants to shrink swollen nasal passages, mucolytics medications to clear mucus, water(hydrated helps in drainage of mucus). pain killers to help relieve the pain; Antibiotics for Acute Bacterial sinusitis; 

Epilepsy

1) It is called also Fits. It is a neurological illness. 

2) Epilepsy is seizure disorder. These seizures take place repeatedly and arbitrarily .

3) During a seizure clusters of neurons (specialized cells transmitting nerve impulses) in the brain become temporarily impaired or are active at the same time)

4) Demographics: Common in urban and rural area and among all ages 

5) Frequency: varying from once a week to once a year

6) Duration: one / two minutes to hours

7) Neurons send a message using electrical signals relayed from neuron to neuron called firing. The communication i.e. information interchange among separate parts of the brain via electric currents. When there is a short circuit at some point then that particular part of the brain or sometimes the whole brain stops working temporarily.

8) Majority of the people get back to their normal self within fifteen to thirty minutes after a seizure as if nothing happened or at least no permanent damage has occurred to the brain

9) Diagnosis: Brain imaging techniques like MRI, CT scans and EEG (electroencephalogram) for detecting electrical activity in the brain and looking for anatomical abnormalities like brain tumors or abnormal blood vessels that could be causing the seizures 

10) Treatment: completely treatable using anti-epileptic drugs/ anticonvulsants and sometimes epilepsy surgery is required for anatomical abnormalities like brain tumors causing the seizures 

12) ketogenic diet forcing body to burn fat instead of carbohydrates

1916-1930

First Great Migration. was the movement of six million African-Americans out of the rural Southern United States to the urban Northeast, Midwest, and West that occurred between 1916 and 1940. In the early 1900s, more than 90 percent of the African-American population lived in the American South and in 1900, only one-fifth of African-Americans living in the South were living in urban areas.

1980-1988

On 22 September 1980 Iraq invaded Iran to replace Iran as the dominant Persian Gulf state, resulting in stalemate with both sides claim victory Iraq failing to annex Iranian territories and Iran failing to topple Saddam Hussein

The periodic table was created by Dmitry Mendeleyev (1869) at University of St. Petersburg.

Scientists have discovered 94 naturally occurring. Majority (over three-fourths) of the natural elements are metals. The periodic table is the set of the elements written in a fashion pointing out the similarities in the properties of the elements.

The chemical properties of an element are dependent on the number of electrons in its outer shell. In the periodic table elements of the same group have the same number of electrons in the outer shell and have similar properties. The properties change gradually along periods (rows) in the table.  The major groups are 

1) Metals: Group 1A (alkali metals), 2A (alkaline earth metals), and 3-12. (good conductors of heat, malleable, ductile and shiny look). 

2) Non-metals: (poor conductors of heat, non-malleable or ductile and not shiny (Nitrogen, Oxygen)

3) Halogens: Group 7A/17 (reactive nonmetals) (fluorine (F), chlorine (Cl), bromine (Br), and iodine (I))

4) Noble gases: Group 8A / 18th (colorless and unreactive) (Helium, Neon, Argon)

Most reactive metal francium (man-made)

Most reactive metal is cesium (natural)

Least reactive element Helium 

Most electronegative fluorine 

Least electronegative francium

Lowest density Hydrogen 

Highest density Osmium.

Most common element Hydrogen

Most abundant element on earth’s crust oxygen (followed by silicon)

Most abundant element by weight iron

Rarest or scarcest element is astatine 

Lightest element Hydrogen 

Heaviest natural element is the metal uranium

Most flammable element hydrogen

Most flammable chemical chlorine trifluoride, ClF3.

Element with the highest melting point Calcium

Element with the lowest melting point Helium 

Element with the highest sublimation point Calcium

Most expensive natural element Lutetium

most conductive silver

least conductive Sulphur

highest measured radioactivity comes from the element polonium.

Most corrosive-resistant iridium

Copper is also the only metal that is naturally antibacterial
