Twins are two babies from only one mother at the same day of birth. [1] Twins can born in two possible ways. One way is that only one egg fertilizes and later splits into an identical twin. The other way is that two eggs are release and met one sperm: this gives a non-identical twin. Generally, a third of twins are identical twins and second-third of twins are non-identical twins.

Non-identical twins are become pregnant with at the same time. Rarely, in this type, the twins can have different fathers. [2] First, one egg meet with one sperm and they fertilize. Later, one sperm met the fertilized cell, so one egg meets two sperms. So, this make the twins can have two different fathers but one same mother. Non-identical twins share only half of their genes, so their faces can might be very similar or very different.

Identical twins are formed by splitting eggs. They split for no reason.  But when they split, they share exact same genes. Based on today’s research, the egg splits because of the ovulation-including drug, the treatment can cause more splitting system. [3]

We can determine twins whether they are identical or non-identical by number of the placenta. If they have only one placenta, they are identical twins. If they have two divided placenta, they are non-identical twins.

Today, many people are arguing about the topic whether stem cell research is good or not. Those who think that we can not kill one’s life for others’ lives might say that stem cell research is not good. However, I think sperm cell is good for two major reasons: to save many peoples’ lives and to not make aborted babies’ lives unworthy.

First of all, if the stem cell research proceeds, many diseases can be cured. Now, many people are suffering from diseases that can not be cured. However, if we can start the stem cell research, we can save a lot of people who are suffering from many kinds of diseases: Parkinson’s disease, Alzheimer, heart disease, spinal cord injuries, replace destroyed organs, and reduce the risk of transplantation. If we can cure these diseases, almost half of world’s population will increase. Also, if we keep the stem cell research working, we could know better about humans’ bodies. If we can know better about human bodies, we can also make good medicines or helpful medicines for human bodies. So, the stem cell research will give a huge benefit to the medical improvement.

Second, these days many young mothers kill their babies because they are too young or too poor to have one. Doctors do not have the right to not kill the babies, if the mothers want to they should follow women’s words. Then, anyway the babies will die so poorly. But what if we make the babies’ deaths more valuable? The babies die without doing something or living the life. But if we use babies’ stem cells to cure somebody, it will not make poor young lives unworthy. Therefore, I think the stem research is good.

For these two reasons, I think the stem cell research is useful. However, I think it is not the best idea. I know that we can save a lot of people who are suffering from many kinds of diseases. However, to save some humans we are killing other humans. If we use aborted babies to the research, young mothers will not really feel sorry for their babies, anymore. In my point of view, the stem cell research is useful, but not the best way to make the world develop.

Frits Zernike

Frits Zernike was born in Amsterdam, Netherlands on July 16th, 1888. [1] Carl Frederick August Zernike’s, who was math teacher and a head of a primary school in Amsterdam, second son of six children. Frits Zernike was influenced a lot by his father. His father had a lot of interest in Science, so he produced a series of elementary books. Also, he had an article about his credit. Actually, it was not only his father that influenced him: his mother and brother. His mother, Antje Dieperink, was also the mathematics teacher. One of his brother was a physics professor.

From 1938 to 1948, he solved the problem of the influence of lens aberrations on the diffraction pattern at a focus. At first, his discovery of the phase-contrast phenomenon did not really capture the attentions from the public. However, after the coopration with German C. Zeiss,  people started to have attentions on his work. Later, his work was recognized by the Royal Microscopical Society for making the phase-contrast microscope.  Also,  he was awarded the Rumford Medal of the Royal Society and an honorary doctorate in Medicine from the University of Amsterdam. At the last, he got Novel Prize for the formation of phase-contrast microscope. Frits Zernike’s discovery also helped coherence theory’s formation. [2]

              Iran has a variable climate. In the northwest, winters are cold with heavy snowfall and subfreezing temperatures during December and January. Spring and fall are relatively mild, while summers are dry and hot. In the south, winters are mild and the summers are very hot, having average daily temperatures in July exceeding 38′C. On the Khuzestan plain, summer heat is accompanied by high humidity.

               Iran’s about half is mountainuos and the rest half is the desert and the fields.

              The biggest environmental problem Iran currently faces is air pollution, especially in the capital city of Tehran, but also in regional cities like Tabriz.  About 1.5 million tons of pollutants are produced in Tehran annually, with carbon monoxide from car exhaust making up a large percentage of these pollutants. Most of Tehran’s nearly 2 million cars are over 20 years old, with poor fuel efficiency and lacking catalytic converters and the ability to use lead-free gasoline.  Many of these cars are domestically produced Paykans, manufactured by the Iran Khodro company.  Leaky engines and cars spewing black smoke are a familiar sight contributing to the city’s hazardous air pollution, as well as its infamous traffic snarls.  In January 2002, President Khatami declared that “from now on, all the Iranian-made cars will be provided with favourable standards for fuel consumption.”  Khatami also pledged to move Iran towards lead-free gasoline in the near future.

                In Iran, 43.1% was origianlly forest. 1.5% is left now. They are sub-tropical and temperate forests. None of the froests are protected.

              0% is endemic.

          Google is a major player in the online advertising industry. Every time you search Google, you’ll see ads displayed along with your results. Those ads are never “mixed in” with the results – there is no “pay to play” on Google… which is one of the reasons Google became the most popular search engine in the first place. But the sponsored text-link ads above and to the right of the results generate a great deal of money for Google. These ads are known as “Google Adwords.” Those who wish to advertise via Google can learn more on Google’s Adwords page. (http://www.boutell.com/newfaq/sitespecific/googlemoney.html)

            I think logoease is a good web. There were not many kinds of logos but we could change the color and size. Moreover, I could add lines and text. Adding text was really cool. If I put my logo on the T-shirt, I will like my T-shirt!
