Слайд 11900 - Karl Landsteiner discovers blood groups
1940 - Karl Landsteiner
discovers Rhesus
Слайд 2Blood type is basically absence or presence of different antigen
proteins on the surface of erythrocytes (red cells) and antibodies
in blood plasma.
Слайд 3What they all have in common, though, is that scientists
of today have no idea of why and how blood
types occurred and developed.
They have no evident functions, except getting in the way of blood transfusions.
Слайд 4Blood Type A (II) is 20 million years old, it
came to us from deep monkey age. It has antigen
A and resists antigen B.
Blood Type B (III) is 3,5 million years old, it occurred as a mutation of Type A. It has antigen B and resists antigen A.
Слайд 5Blood Type 0 (I) is 2,5 million years old, it
supposedly occurred because malaria virus latched itself easily to the
existing antigen and killed the cell. Type 0 has no AB antigen, so it’s universal donor blood. And it’s world’s most common type.
Blood Type AB (IV) is the youngest in pack, it emerged after Type 0. It has both A and B antigens, so it can accept any blood, but it’s useless as donor blood.
Слайд 6Rhesus or Rh factor isn’t a sugar, but a variety
(50 different kinds) of complex proteins, found in erythrocyte membrane.
90% people have most them, but around 10% people don’t.
Allegedly Rh factor is connected to diseases carried by cats, so nations and regions, where cats were not known, had no such an antigen
Слайд 7Unlike blood type ABO, Rhesus difference will provoke immunity reaction
between mother and her child
Слайд 8What’s your blood type?
Have you ever done blood transfusion?
What do
you think was the reason blood types occurred?
Слайд 1014 May 1796 Edward Jenner tests vaccine
Слайд 11First patient of Jenner was James Phipps, an eight-year-old boy.
He was vaccinated against smallpox and experimentally proved to be
immune to the disease after it.
Less than 2 centuries after, in 1979, smallpox was announced as a fully eradicated disease.
Слайд 12
Do you think vaccination is good or bad? Why?
Слайд 13
Is vaccination mandatory in Ukraine?
Have you been vaccinated?
Слайд 14 1. PRO vs CON
Vaccines can save children's lives.
Vaccines can cause
serious and sometimes fatal side effects.
Слайд 15 2.PRO vs CON
Vaccines contain harmful ingredients.
The ingredients in vaccines are
safe in the amounts used.
Слайд 16 3. PRO vs CON
Vaccines eradicated smallpox and have nearly eradicated
other diseases such as polio.
Most diseases that vaccines target are
relatively harmless in many cases, thus making vaccines unnecessary.
Слайд 17 4. PRO vs CON
Major medical organizations state that vaccines are
safe.
The pharmaceutical companies, FDA, and CDC should not be trusted
to make and regulate safe vaccines
Слайд 18 5. PRO vs CON
Vaccines provide economic benefits for society.
The government
should not intervene in personal medical choices.
Слайд 19 6. PRO vs CON
Vaccines protect future generations.
Mandatory vaccines infringe upon
constitutionally protected religious freedoms.
Слайд 20 7. PRO vs CON
Vaccines protect the "herd“, providing shield for
unvaccinated people.
Vaccines are unnatural, and natural immunity is more effective
than vaccination.
Слайд 21About 30,000 cases of adverse reactions to vaccines have been
reported annually to the Vaccine Adverse Event Reporting System since
1990, with 10-15% classified as serious, meaning associated with permanent disability, hospitalization, life-threatening illness, or death.
Слайд 22The Centers for Disease Control (CDC) estimated that 732,000 American
children were saved from death and 322 million cases of
childhood illnesses were prevented between 1994 and 2014 due to vaccination.
Слайд 2524-day, 240-mile Salt March began on March 12, 1930
Слайд 26The manufacture of salt in India was a government monopoly
established in 1882.
Though salt could be obtained from the
sea, it was a crime for any Indian to possess salt without having purchased it from the government.
This ensured that the government could collect a salt tax.
Слайд 27On March 2, 1930, Gandhi ( the leader of the
Indian National Congress) wrote a letter to Vice-roy Lord Irwin.
Beginning with “Dear Friend,” Gandhi went on to explain why he viewed British rule as a “curse” and outlined some of the more flagrant abuses of the administration.
Gandhi warned that unless the viceroy was willing to make changes, he was going to begin a massive program of civil disobedience.
Слайд 28Salt, sodium chloride (NaCl), was an important staple in India.
Vegetarians, as many Hindus were, needed to add salt to
food for their health since they did not get much salt naturally from their food.
Salt was often needed for religious ceremonies.
Salt also was used for its power to heal, preserve food, disinfect, and embalm.
All of this made salt a powerful emblem of resistance.
Слайд 2961-year-old Mohandas Gandhi led an ever-growing group of followers from
the Sabarmati Ashram to the Arabian Sea.
Слайд 30Upon arriving at the beach on the morning of April
6, 1930, Gandhi reached down and scooped up a lump
of salt and held it high.
This was the beginning of a country-wide boycott of the salt tax
Слайд 31In all, about 90,000 Indians (including Ghandi) were arrested between
April and December 1930.
In January 1931 the Gandhi-Irwin Pact was
signed and Indians were let to own and make their own salt.
Eventually – but indirectly - this caused the fall of the British rule over India in 1947.
Слайд 37Have you heard about Gandhi's March before? How was it
different from other protests?
Have you ever protested against anything? Did
it help?
Is it good or bad to protest against the current rules or laws? Why?
Слайд 38Why is boycott called boycott?
What is the purpose of a
trade union?
Why do some people think it's a bad thing
to follow other people?
Слайд 39Are there any criticisms of Gandhi that you know of?
Why
do you think Gandhi never won the Nobel Peace Prize?
Gandhi
believed people should lead as simple a life as possible. Do you think people can do this today?
Слайд 40What does it take to be a respectable leader and
lead people?
Are you a good leader? Do you think other
people would follow your lead?
Why is good leadership important?
Слайд 41What is the most important thing a leader must remember
about leadership?
Have you ever been in positions of leadership?
Who in
the world do you think possesses the greatest leadership skills?
Слайд 42Is there always stress with leadership?
Does leadership exist in a
romantic partnership?
Do you think people with no leadership skills have
a more or less happy life?
Слайд 43
Is leadership an art or a science?
Слайд 46On February 18, 1930, Clyde W. Tombaugh, an assistant at
the Lowell Observatory in Flagstaff, Arizona,
discovered Pluto.
Слайд 47American astronomer Percival Lowell first thought there might be another
planet somewhere near Neptune and Uranus.
He noticed that the
gravitational pull of something large was affecting the orbits of those two planets.
Слайд 48However, despite looking for what he called "Planet X" from
1905 until his death in 1916, Lowell never found it.
Thirteen
years later, the Lowell Observatory (founded in 1894 by Percival Lowell) decided to recommence Lowell's search for Planet X.
It took a year of research and a powerful telescope to find it.
Слайд 49On what would have been Percival Lowell's 75th birthday, March
13, 1930, the Observatory publicly announced to the world that
a new planet had been discovered.
Слайд 5011-year-old Venetia Burney from Oxford, England, offered to call Planet
X “Pluto”.
The name mentions both the assumed unfavorable surface
conditions (as Pluto was the Roman god of the underworld) and also honors Percival Lowell, as Lowell's initials make up the first two letters of the planet's name.
Слайд 51Pluto was the smallest planet of the Solar system (2/3rds
of Moon) and the only planet whose orbit actually crossed
that of another planet (Neptune)
Слайд 52In 2003 they found another planet further from the sun
that looked a lot like Pluto. And there are many
more similar dwarf planets in the Kuiper belt .
The main criterion of having the planet status, still, is the ability to sweep own orbit from the debris and junk, which Pluto is not the best at, since it’s both small and very slow.
Слайд 53It takes Pluto 248 years just to make one orbit
around the sun, so between it started being looked for
in 1905 and losing its planet status in 2006 he didn’t even make half a round.
Слайд 54In 2015 Pluto had a real peak of popularity, because
finally its pictures were made in good quality.
The New Horizons mission
reached Pluto in July 2015, but it still will take several months into late 2016 to send all the data it gathered during a few day fly-by. Because data has to fly 3 billion miles of space for 1,000 bits per second.
Слайд 55Have you ever wanted to travel into space?
What drives people
to travel to other worlds?
In your language, are chocolate
bars and cars named after parts of our solar system?
Слайд 56Have you followed the Pluto popularity on the internet? What
do you remember the most?
Why do you think so many
people were so eager to see the hi-def color pictures of Pluto? What made it so popular?
What other planets of the Solar System you know? Which would you like to see?
Слайд 591930 Auguste Piccard makes the first balloon gondola to reach
stratosphere
Слайд 60On 27 May 1931 Piccard and his assistant, Paul Kipfer,
reached a record of 15,785m in a pressurised aluminium capsule
attached to a large hydrogen balloon.
Слайд 61Piccard wanted to measure the activity of cosmic rays and
investigate Einstein's theory of relativity.
Слайд 62The thing that stood out was that everything seemed to
go wrong, right from the get-go. Kipfer looked out of
the window while they were doing a final check and he could see chimneys going past – they had already taken off. And then there was the leak, the spilled mercury and the bit when they nearly asphyxiated because they didn't have enough air. It was a catalogue of terrifying lurches from one catastrophe to another
Слайд 65Would you like to experience such a trip?
Why do you
think people agree to such adventures?
Is it better to travel
or to arrive?
Слайд 66What was the most difficult travel in your life?
Have you
ever launched any balloons?
Is it hard these days to make
a video of Earth from the balloon? Have you ever tried?
Слайд 691931 Harold Urey discovers Deuterium
Слайд 70Deuterium is a “heavy” hydrogen with one neutron in the
nucleus.
Слайд 71Most of deuterium was produced during Big Bang 13,8 billion
years ago
In universe the average ratio is about 26 atoms
of deuterium per million hydrogen atoms
Earth has 156 atoms of deuterium per million hydrogen atoms
Слайд 72It is believed to prove the theory, that Earth oceans
were formed by comets (solar activity enhances the isotope separation
in ice of comets, producing deuterium).
Слайд 731932 Ernest Lawrence of the University of California, Berkeley first
operates a 27-inch Cyclotron
Слайд 76The particles are held to a spiral trajectory by a
static magnetic field and accelerated by a rapidly varying (radio
frequency) electric field
Cyclotron is used to produce radio nuclides by hitting particles with each other
Слайд 781932 James Chadwick discovers neutron
Слайд 79The work was done based on Ernest Rutherford’s work and
discovery of a proton in 1917, and under his personal
leadership.
Слайд 80In 1932 John Cockcroft and Ernest Walton (under Rutherford’s leadership)
bombarded Lithium with high energy neutrons, electrons and protons and
succeeded in transmuting it into Helium
Слайд 82Have you heard about a theory that water on Earth
is comet-brought? What do you think about it?
Where do the
comets come from?
Слайд 83What do you know about Big Bang?
What’s the difference between
proton and neutron?
Why do scientists collide particles?
Слайд 861902 Willis Carrier invents the first electrical air conditioning
Слайд 87It was designed to control the humidity in his New
York publishing house. It helped the ink to dry faster
and smudge-free and kept the paper from expanding and contracting.
Слайд 881914 first air conditioner installed at home
The unit in the
Minneapolis mansion of Charles Gates is approximately 7 feet high,
6 feet wide, 20 feet long and possibly never used because no one ever lived in the house.
Слайд 891928 Thomas Midgley, Jr. discovers Freon (chlorofluorocarbon)
Слайд 90Freons consist of carbon, chlorine, and fluorine (hence the name
chlorofluorocarbon).
They are used as solvents (dissolvers) , propellants and
refrigerants.
Production of Freons is restricted since they actively deplete Ozone layer
Слайд 921931 Schultz and J.Q. Sherman creates the first modern-type air
conditioning, the window room air conditioners available from 1932
Слайд 93Invention of air conditioning has greatly invested to migration into
Sun Belt regions and settling the tropical regions of the
earth
Слайд 94Does Ukraine belong to a Sun Belt place?
What kinds
of aircons do you know? Which are most popular these
days?
Слайд 95Do you have an air conditioner at home?
How often do
you use it?
Do you catch an aircon cold often? Why
does it happen?
Слайд 96Do you think people in tropical countries use air conditioning
a lot?
Have you ever been to a place where you
wouldn’t be able to survive without air conditioner?
Слайд 97What temperature is comfortable for you to stay or work
in?
Why are conditioners bad for environment? Is it safe to
use them?
Слайд 1001932 An American George G. Blaisdell founded Zippo Manufacturing Company
Слайд 101He created his first new lighter in 1933, drawing the
idea from the Austrian lighter produced by IMCO
Слайд 102Zipper and Zippo sounded very modern to the American ear
and thus Blaisdell decided to use it
Lighter became increasingly popular
among the soldiers in the WW2, and after it. Many advertisement campaigns and legends brought it fame and glory.
Слайд 105 Over 500,000,000 Zippo lighters
have been produced Since 1933
The
anniversary lighter was made in 2012.
These days because of
non-smoking campaign Zippo produces everything from watch to clothes
Слайд 106Zippo is famous for being windproof
Until very recently most of
the campers favored it or matches or other fire sources
It
runs on 50-50% mix of 93 octane gasoline with acetone which you can even mix at home
Слайд 107These days campers prefer butane torch lighters
Слайд 108Ferrocerium, which is basically a lighter flint, was invented in
1903.
It’s made from [Fe]rrum and [Ce]rium
Слайд 1101961 - First disposable butane lighter is introduced by Cricket.
Слайд 1111966 - Molectric 80 –first piezoelectric lighter
Слайд 116Are you a matches or a lighter person?
Слайд 117
Where and what for do people usually use lighters?
Слайд 119
What do you use to light up the gas stove
at home?
Слайд 120When you go out on a picnic, what source of
fire do you usually take?
Слайд 121Why do people use expensive lighters these days?
Слайд 122What tricks can you do with a lighter?
Слайд 125Zippo owners are always proud of a thousand ways to
stylishly light their Zippos, have you ever seen one in
a movie or in real life?
