BEE AND FLOWERS

             Karl Frich (1886-1982) was an Austrian zoologist who studied how bees communicate with other. In 1973 he received a Nobel Prize for his work on animal behavior.

             The sent from a flower that has produced nectar through the air. It may stimulate the receptor cell of a honey bee and the insect flies towards it. As it get closer, the bee uses its eyes to find the flower, its eyes are sensitive to ultraviolet light. This make some of the pale markings we see in normal light stand out more distinctly to help the bee identify the flower. Some of the markings are lines running down the inside of petal. They are called honey guides and direct the bee towards the nectar.

RESPIRATORY STRUCTURES IN ANIMALS

                           The simplest respiratory is surface, is the body covering. You may have noticed that some animals are small and shaped in a way that allow the body surface of the animal to be the gas exchange surface. However, as animals, as animals become bigger and complex their body surface to volume ratio gets decreased. Therefore, gaseous exchange through their body surface by simple diffusion become inefficient. Thus, s

COUNTRIES AND CULTURE

What is a culture?
                             Is it characterized by art or literature? Does it include actions, feelings, or thoughts? Is it ideas, objectives, or ways? What about beliefs or values, or customs or tradition? Is it something as simple as a field of activity or as complex as a never ending experiment? Culture is all of these. In everyday conversation, the word culture might refer to such fields as literature, art, or music; yet scientists who study culture see it as something more complex, a way of life as well as acting, feelings, and thinking. And even within these ‘definitions’ of culture there are different views on what exactly culture is. Western Culture began in Ancient Greece. There and in the Roman civilization it developed until the start of the Middle Ages when it largely vanished from Europe. During the Middle Ages, Western Culture resided, instead, in the Arab / Persian world to a modest degree.

MEDICINE

                      The practice of medicine is based on diagnosis and treatment. A hundred years ago, the physician felt the pulse and came to various conclusions about illnesses.
             He had only a few instruments to diagnose a disease. Within the last hundred years, medical technology developed. Now the physician has sophisticated medical instruments to diagnose diseases.
              X ray machine that was invented in 1895, came into regular use.

            Medical technology continues to develop very rapidly. Today the changes of the body can be observed and measured.      These findings are the key to diagnosing diseases and deciding treatment.

                   The E.C.G machine was invented during the last century. It is used to find how the heart works. The damage caused by a heart attack can be measured on this machine.

                Modern technology is able to support failing organs. Ventilators are used to maintain oxygen levels to assist breathing.

           Sir Alexander Fleming, whose discovery of penicillin led to the discovery of many other antibiotics. The antibiotics help in treating a large range of bacterial infections. 
                                  Modern technology has helped immensely to develop surgery. Now lasers are used in surgery. Kidney stones and gall bladder stones are removed through laser surgery. Laser treatments are used for treating eye diseases too.
      Medical science and technology has developed so much that surgeons transplant organs from one body to another. Kidney transplantation was first attempted in 1902. Today it is a well established operation. Heart transplantation was first performed in South Africa, in 1967. It was done by the surgeon, Christian Barnard.
                                          Immunization programmers are carried out to give protection to children. This has greatly decreased previously common diseases. 

ENCYCLOPAEDIA

 

                        The encyclopaedia has developed from the dictionary in the 18th century. A dictionary is mainly on worlds and their definitions. It provides limited information, for the word defined. Sometimes the definition given in the dictionary may not give enough understanding of the word to the reader. He may not understand the meaning, or significance of the word. He may not understand the broad meaning.
                An encyclopaedia is a complete summary of information. This information can be on all branches of knowledge or a particular branch of knowledge.
               An encyclopaedia on the other hand gives a full account on the subject. It gives the most relevant knowledge gathered on that subject. It often includes maps, illustrations, charts. as well as statistics to show relationships.
             The word "encyclopaedia" comes from the classical Greek word meaning, " a general education" The idea of producing an encyclopaedia is very old. The term was first used in 1541.

The Pinnawala Elephant Orphanage

                It was started in 1975. There are baby and adult elephants in the orphanage. They are all rescued elephants. Farmers shoot at elephants when they come to their villages. Sometimes they throw fire brands to scare them away. Some elephants fall into pits, well and water-holes, when come in search of water in the dry season. Some injured elephants fall on the way. They cannot get up because of pain, hunger and thirst. Such elephants are rescued and brought to the orphanage.

Discovery of Antiseptic

                Joseph Lister was born in Upton, Essex, in England in 1827. He was educated at the universities of London and Edinburgh, 1852. In 1856 he became a surgeon in the Edinburgh royal Infirmary or hospital. In 1861 he was appointed surgeon of the Glasgow royal Infirmary in the new surgery unit designed to reduce gangrene and other infections. At that time, it was more dangerous to go to hospitals for surgery. One famous doctor said that it was very dangerous to to go to hospitals for surgery than to be a soldier in a war. This was because many died from infection. Despite his efforts to keep surgical instruments and rooms clean, the mortality rate remained closed to 50 percent.
