Biology


1. What is coeliac disease?

Coeliac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food.

Is a lifelong condition that occurs when gluten triggers an abnormal immune system response that damages the small intestine. Tony, finger-shaped tissues (villi) line the small intestine. The villi create a large surface that absorbs vitamins, sugars and other nutrients as food passes through the small intestine.

The function of the villi is to increase the surface area of the intestine so as to increase its capacity to absorb nutrients and liquid from food passing through it.

2. What happens to a person with coeliac disease?

They will inevitably cause themselves serious harm, primarily to the intestine and secondarily to other organs. The walls of the intestine are lined with minute finger like projections called villi. Intestinal villi absorb nutrients from ingested food. When a Celiac ingests gluten, his/her villi flatten out and no longer perform their function. Nutrients in food are thus no longer assimilated and are passed out of the body in the faeces. Celiac’s who ingest gluten effectively put their intestine out of service; their bodies no longer receive the necessary nutrition and consequently they lose weight, their growth is stunted and they become ill. Gluten intolerance symptoms vary, the most noticeable being diarrhoea, abdominal swelling, loss of appetite and vomiting. However, sufferers may also develop other less immediately apparent symptoms, such as iron and calcium deficiency.

People who have celiac disease may have periods when their symptoms seem worse. Or symptoms may sometimes not be noticed at all.

A child who has celiac disease may not grow and gain weight normally because the child's body is not absorbing needed vitamins and other nutrients. Children who have untreated celiac disease can become very ill. They may need hospitalization for treatment with fluids and medicine to restore nutrients. These treatments are usually short-term, and most children recover completely.

Adults who have celiac disease have a slightly higher-than-average risk of lymphoma, which usually develops in the intestine. They also may have a slightly increased risk of developing cancer of the esophagus.

3. Treatment - how do we deal with coeliac disease?

Once you suspect that you have celiac disease, visit your doctor. A doctor will conduct a blood test, or a small bowel biopsy to determine whether the patient is celiac.
If the test proves that you are celiac, you must take care of yourself. Remove gluten from your diet completely, and read the ingredients on everything you intend to consume. You should specifically look for “gluten free” foods rather than just “wheat free.” There is no known cure for celiac disease, but doctors will advise you to live gluten-free.

Chemistry - Recycling of Metals

a.     What will happen to the world if there are no more metals?


            Metals play an important part in modern societies and have historically been linked with industrial development and improved living standards. Each metal has its especial uses and very important in our life.


Sintered Metals / Powder Metals
Sintering Equipment Includes Numerous Continuous Belt FurnaceState of the art computer controlled coordinate measuring equipment and a Cordax measuring machine assure dimensional accuracy.
Sintered Metals


For example:

-Copper and aluminium wire are used to carry electric current.
-Copper, aluminium and iron are used to make domestic utensils and factory equipment.
-Thin foils of aluminium are used for wrapping cigarettes, medicines, confectionery, etc.
-Aluminium is used for making angles, doors, pipes, etc. which are used in the construction of houses.
-Metals such as sodium, titanium, zirconium, etc. are used in generation of nuclear energy and in space science projects.
-Mercury is used in thermometers.
-Magnesium metal is used as a strong reducing agent to prepare other metals.
-Gold and silver metals are used to make jewellery.
-Thin foils of silver and gold are used to decorate sweets.
-Uranium metal is used to generate nuclear energy.
-Titanium metal is very hard, resistant to corrosion, light, has high melting point and is good conductor of heat and electricity. Because of its unique and useful properties titanium is sometimes called ‘the wonder metal’.


We can see so many uses of metals so without metals, it would be difficulty in making things that we are using. There will be no more domestic utensils, factory equipment, medicines, furniture, appliances, tools…
b.     Is it important to recycle metal?
Yes, it is.
c.      Thus what are the reasons to recycling metals? Isn’t it easier to obtain metals through its original from through extraction of metals?
    
Reasons to recycling metals:

-It is easy and cost-effective to recycle metal, and metal can be recycled continuously without losing its properties.

-When it is easy to do, human should recycle rather than to continually deplete the earth’s natural resources.

-It saves the Earth.

-It saves Energy. Recycling used materials reduces energy requirements in many manufacturing processes such as refining and mining. Recycling materials like aluminum and glass can greatly reduce the pressure on energy resources.

-It helps extend the life and usefulness of something that has already served its initial purpose by producing something that is useable.
-It saves Money. With the reduction in costs to re-manufacture used metal through recycling, there is even more money to be made across the board. This impact that metal recycling has, not only helps protect the environment and protects our natural resources for generations to come, but creates in the hundred thousands of jobs across the world.




Some of the effects Recycling of metals has on the environment.


- The environment is not a single thing - conservation of resources, energy, air and
water pollution, and psychological and political aspects are often competitive, and what may help in one area may be harmful in another

-As lot of debris is collected everyday for recycling, and so the recovery sites can become unhygienic. Abandoned dump sites can severely damage the surrounding environment. Harmful chemicals in the trash, can mix into water and soil. This can cause water and soil pollution and harm plants and fish in the streams and lakes.
-In addition to conserving energy resources, metals recycling also reduces mining and beneficiation activities that disturb ecosystems.  Though land used for the extraction of primary metals represents under 0.1% of Earth’s terrestrial surface, exploration and mining activity can affect surrounding ecosystems due to necessary infrastructure and by dispersing metal compounds into the environment.

d.     Think of reactive ways that we can also play a part in recycling metals?
For some metals you do not use anymore, we can modify it and create it to be another thing we can use. For example: if we don’t use the cans anymore, we can cut the cover, decorate the outside. Put in woodland and then planting by seed. Or the steel we can stick them and then bent it, create it to decorate.

Technology Task

1. What is MTV?

formerly an initialism of Music Television, is an American network based in New York City that launched on August 1, 1981. A cable and satellite television channel that broadcasts popular music and promotional music videos.

2. Effects of MTV on the youths of today?

-Keeps our knowledge fresh and up to date by providing us with the latest things that are happening around us.

-Allows us to represent ourselves to the rest of the world.

-Youths are in control and choose a media that they feel like compliant their mood.

-Youths in control of their viewing and the new waves of technology and more channels that appeal to every single possible music taste.

3. Effects of MTV on you - why do you like/dislike MTV?

- MTV help me to update the new music type, fashion style and even language (because I'm international student). I can learn English from MTV.

- I find out MTV is more than just music because there are tons of different things in this channel.

- I like MTV because everything is in 1 channel, even the advertisements are interesting and entertaining. 

-MTV is the channel I can relate to.

4. How does MTV change your life?

-MTV includes musics and real life shows.

-Music changes my life because almost songs are telling the story of life and it's beauty, wonder, struggles and causes. When I'm sad I can listen to a song about struggles and I might feel better. It's really change my mood.

-Real shows are the key. The reason they called "real show" because it relates to our life. Sometimes in the real show I find that I have the same situations as a character so I feel I'm not different from others. Others also have a moment that it worse like me.


-MTV is like a morning paper for youths and for me. It likes a routine for the day to update the world by shows, music, advertisement, fashion, style, your idols, your idols information...


-MTV is also a part of art that might give me the ideas of art, creations or innovations.

Chemistry - Term 3

A. History of naming formula

Naming formula or the language of chemistry was largely based on the work of Antoine Lavoisier (Father of Modern Chemistry). He worked to translate the archaic and technical language of chemistry (about 19 century). Then the names of formula was developed by a group of scientists. Elements are represented by symbols. Each formula has a name unique to that formula.

B. What is the concept behind the naming?

In the past, the chemists used formula or elements by drawing or using shape to describe the formula. But it very hard to understand so that naming the formula made it easier to understand and to use at more interesting for people to learn. Naming the formula allows chemists and people to communicate in words rather than in chemical symbols.

C. Does "ate" represent 3 Oxygen atoms?

No, it doesn't. There are many formula that have "ate" but more than 3 oxygen. Example: PO4 (phosphate), SO4 (sulfate)
