Recommended: Experiments on antibiotic effectiveness
Antibiotics have played a major role in our society thanks to Sir
Alexander Fleming's careful observations in 1928. Without it, many lives
would be in danger due to infectious diseases.
Antibiotics are chemical substances produced by various species of
microorganisms and other living systems that are capable in small
concentrations of inhibiting the growth of or killing bacteria and other
microorganisms. These organisms can be bacteria, viruses, fungi, or
animals called protozoa. A particular group of these agents is made up of
drugs called antibiotics, from the Greek word anti ("against") and bios
("life"). Some antibiotics are produced from living organisms such as
bacteria, fungi, and molds. Others are wholly or in part synthetic - that
is, produced artificially.
Penicillin is perhaps the best known antibiotic. Its discovery and
later development is among mankind's greatest achievements. Antibiotics
have enabled the medical profession to treat effectively many infectious
diseases, including some that were once life-threatening.
How Antibiotics Work ?
Antibiotics can be bacteriostatic (bacteria stopped from multiplying)
or bactericidal (bacteria killed). To perform either of these functions,
antibiotics must be brought into contact with the bacteria.
It is believed that antibiotics interfere with the surface of bacteria
cells, causing a change in their ability to reproduce. Testing the action
of an antibiotic in the laboratory shows how much exposure to the drug is
necessary to halt reproduction or to kill the bacteria. Although a large
amount of an antibiotic taken at one time might kill the bacteria causing
an illness, such a dose usually would make the per...

success in the development of safer antiviral drugs, and their use should

In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Throughout The Crucible, Reverend Hale is a faithful and intelligent minister. He comes to Salem as the spiritual doctor to respond to the rumors of witchcraft, which have been flying in Salem after the strange illness of Reverend Parris’s daughter, Betty Williams. Hale never declares witchcraft, but he relies on people’s evidence of it because of the large amount of evidence. As the play goes on, Hale’s intelligence leads him to other sources of hysteria and accusations. The change in the character of Reverend Hale is noticeable throughout the play. In The Crucible by Arthur Miller, Reverend Hale grows from a confident, authoritative figure, trying to end witchcraft in Salem, to a regretful, fair character who wants to end injustice and save innocent lives.
When most American people think of Germany, they think of sports cars made for the autobahn, sauerkraut, Adolf Hitler, and the Holocaust. Compared to Germany, when most American people think of Japan they think of sushi, Godzilla movies, Japan’s attack on Pearl Harbor, and the atomic bombings of Hiroshima and Nagasaki. World War II was such a significant event in history that almost 70 years after it came to an end, today’s younger generations often associate former Axis controlled countries with the war. People around the world are filled with disgust and immense hate when they hear the name Hitler, mainly because of his leadership under the Holocaust; which was the discriminatory mass genocide of 11-17 million people, the vast majority of which were European Jews. Hirohito, former Emperor of Japan, should strike a similar bell with people when they hear his name because Japan carried out genocide on Chinese civilians and soldiers in World War II. Japan’s attack on the Chinese city of Nanking, was one of the most atrocious events in history. This event has been named both the Nanking Massacre and the Rape of Nanking. The torturous, violent techniques used by the Japanese army upon Chinese civilians and soldiers including dehumanizing them, addicting them to drugs, and other perverse and violent acts, are some of the most grosteque methods ever recorded that could only be thought of by sadistic Japanese soldiers. The events committed by the Japanese army in Nanking, are equally as disgusting as the acts that Nazi Germany committed and should become a major topic involved with World War II in the future, despite the lack of light shed on it in the past for various reasons.
The rape of Nanking occurred during World War II by the Japanese onto Chinese civilians. Nanking was a newly established capital in the Republic of China that was a part of the plan of attack for the Japanese to assert its power in Asia. While the Chinese had them outnumbered greatly, the Japanese utilized the power of deception in order to make their way into the city of Nanking. For example, the soldiers would promise the Chinese fair treatment if they were to stop resisting the invasion. This plan worked exceptionally well, as the captives believed what they were told and allowed the Japanese to tie them up. Very few actually resisted the attacks and simply hoped they would be treated better by the Japanese if they complied.
Have you ever wondered what it would be like to have a Japanese soldier barge into your house, rape your mother and sister, and then kill your father, all while you’re being forced to watch? Hopefully not, but unfortunately at one point in our history, that has happened to hundreds of thousands of people of Nanking, China. This Rape of Nanking or Massacre of Nanking can sometimes be referred to as the “forgotten Holocaust of WWII” seeing as it took place close to the start of the Second World War and is not nearly talked about as much as the German Holocaust with the Jews. It all happened in December of 1937, when Nanking fell to the Japanese.
Poe’s frightening stories acts as helpful inspiration for entertainment in the present, and for many years to come. The timeless relevance of his work, and its merciless scrutiny of the human condition, solidifies its place in history and its position of high admiration. In conclusion, the extraordinary-fleeting-tragic life of Edgar Allan Poe will forever remain on record as the tale of an orphan, a gentleman, a soldier, and one of the most prominent literary figures in American history.
Edgar Allan Poe's deplorable life was filled with unfortunate calamity, endless tragedies, and pathetic misery, which inevitably led to his pessimistic view on life and obsession with death. His personal mind frame is automatically conveyed in his essays, which for him was a primary form of expression. Thus, a strong emphasis on somber despondency has proven to be a thematic element of his literary career.
Nanking suffered a severe tragedy in six weeks that its memories fail to erase. The tragedy consisting of rape, murder, and looting will never disappear from the city or its inhabitants. Thanks to John Rabe and several others, thousands of Chinese were able to survive. The history of the massacre was slowly dying, but because of books and museums, the history lives onward. The Japanese have not repaired Nanjing or educated their own country about their own mistakes. The Japanese still refuse to believe that the massacre even occurred even though there are pictures of the event and vital proof. The Japanese have surely left a blood stain in the history of this world.
Edgar Allan Poe born on January 19, 1809, was known as the creator of the modern detective story and innovator of the science fiction genre. Although, people identify him because of his horror stories as well as his haunting lyric poetry, there was a different side of him other than a gruesome, mysterious individual prowling in the shadows of moonlit cemeteries. Poe’s childhood was very tragic and affected his adult life when growing up. Poe was the second son of actors David and Elizabeth Poe. Shortly after Poe was born, his father abandoned the family in 1810 and the following death of his twenty-four year old mother in 1811, left Poe an orphan at the young age of three. Poe was adopted by a guy named john, who was a strict unemotional tobacco merchant and his wife Frances Allan, a week women with health issues. His original grandparents only took in his brother William Henry instead of Poe. He was educated with his father’s aid, in private schools, excelling in latin, writing verse, and declamation. Regardless of his education Poe was looed down upon and was considered an outsider by the upper class of Richmond society. It maybe because his foster parents never legally adopted Poe and also regarding his family background. In Poe’s time adulthood did not support actors in high manners, which this could have been attributed to his reputation. Poe childhood shaped him to be one of the most Famous creative poet there is.
Darcy’s proposals help to manifest his personal growth by showing the difference in his manner, rationale, and result. His haughty words and actions are the crux of his indifference towards the feelings of others in the beginning of the novel. Although Mr. Darcy is ignorant of his own highfalutin attitude at first, the rejection of his proposal by Elizabeth is just the tocsin he needs to salvage the small amount of respect she still had for him. Through her rejection, he comes to terms with his own pride and prejudice against Elizabeth and her family. Also, he realizes that she is not one to marry for money or social status, but she wants to marry a man that she truly loves, which is a surprise to him. This radical modification of his attitude results in a second marriage proposal for Elizabeth, where he genuinely expresses his feelings. Although he is uncertain of her answer, he simply wants to make his love for her known. The slightly astonished Elizabeth immediately recognizes how much the tone and motive in his second proposal have changed from his first and also reveals her love for him. Mr. Darcy’s two proposals do not simply act as means to communicating his feeling to Elizabeth, but as a documentation of his significant change in
When 1937 arrived, Japanese soldiers raided China’s capital of Nanking and began to mass murder citizens. A sole leader of the Japanese Imperial Army was non-existent. There were many of people in power such as generals who allowed these behaviors to occur. Baron Koki Hirota, Foreign minister at the time, proceeded to do nothing while being well aware of the Japanese’s persecution of the Chinese. These unsympathetic murders of those who were thought to be Chinese soldiers as well as woman, children and elderly. This massacre lasted between the 1937 and 1938. Within this time 300,000 Chinese citizens were viciously killed. This genocide is called Rape of Nanking because of raping the woman before killing them. Most likely this group was selected because the second world war happened in Asia. This was significant because a country was able to kill half the population of another. I believe the reason of this Genocide was for Japan to take advantage of China while expand Japan. Most likely the Japanese wished to exterminate China’s entire population.
The life of Edgar Allan Poe was one often colored by tragedy. These tragedies were a strong source of influence for his writings and likely contributed to his focus on the bleaker aspects of life. Born in 1809 in Boston, Massachusetts, Poe’s life with his biological family was short lived. His father, David Poe, left the family only two years after his birth, and shortly after in December 1811, his mother Elizabeth Poe died from illness leaving him an orphan (Quinn 47). The death of a parent at such a young age is something that would undeniably have a profound impact on anyone’s psyche. In the case of Poe, the death of his mother and later the serious illness, and subsequent death of his wife, Virginia, could be seen as one of the strongest motivations for his focus on death and obsession over loss (Quinn 496). This unfortunate childhood was compounded by the difficult relationship Poe had with his foster parents, John and Fanny Allan (Dhahir). Poe’s ...
Both Elizabeth and Darcy are quick to judge each other on their first meeting. Part of the reason Darcy is misjudged is somewhat his own fault, however, as he makes no attempt at following what the townspeople see as common courtesy. While they think he is a good man at first, after he refuses to meet anyone knew they determine that “not all his large estate in Derbyshire could then save him from having a most forbidding, disagreeable countenance, and being unworthy to be compared with his friend [Bingley]” (7). In addition, he does not pay attention to words that might hurt those within ear shot. When Mr. Bingley tries to get him to dance with others, he suggests Elizabeth and Darcy’s swift response is nothing more than an insult to her, “She is tolerable, but not handsome enough to tempt me; I am in no humour at present to give consequence to young ladies who are slighted by other men” (8). Later, as he starts to realize he is beginning to feel something for Elizabeth, he is too proud to admit to these feelings. He describes the realization and the ones that follow it as “equally mortifying”(14).

“Overuse of the drugs in health care and farm animals has increased antibiotic resistance and could contribute to thousands of deaths each year among patients having colorectal surgery, chemotherapy or hip replacements” (YaleGlobal Online). Antibiotics are medicine that can either help bacteria grow or destroy the bacteria. The way antibiotics can help the bactira grow is by the overuse of it. Today, many of the farmers throughout the United States of America mix their livestocks food with antibiotics. Farmers should be banned from mixing their livestock’s food with antibiotics because antibiotics are bad to the humans, antibiotics are unnecessarily and not used right, and antibiotics are dangerous.
