  1. The local grocery stalls and supermarkets sell polished white rice, which is mainly Jasmine rice. Rice have a high glycemic index. I think it can make one get fat, but nobody eat a pure rice diet. There are some fat rice-eating people around me. Brown rice is unpolished rice, the supermarket usually stock these in lower quantity for the health conscious people. Brown layer has some nutrients which is striped when they polished the rice. Jasmine rice is from Thailand, and some other regions grow it too. I don't know the difference of Jasmine rice compared to Basmati rice, maybe the texture of the cooked rice or the glycemic index. Polished rice , a refined food, give a spike to the blood sugar level. It is mainly carbohydrates, according to the food pyramid chart, carbohydrates form a significant portion of the diet and fats should be low in the diet. so I think rice it is not worst than fat.
  2. Some african nations have problems with overpopulation. If there are droughts, famines, the pressure of overpopulation leads to genocides and wars. The UN and aids agencies will need to go there. Suppose there is not much struggle for existence there, your governments pay less for UN operations. However, some african nations may have some corruption. Maybe the new laws will be discarded after some years. or the african governments are unable to do anything, as I suppose these countries are big and don't have effective communications at some areas. or is it that africans are anticipated to enter USA in large numbers ?
  3. According to wikipedia, the minimum rainfall to qualify as rainforest is 68-78 inches. So I think it isn't.
  4. I don't know how the products you've mentioned work. In slow release fertilizer or some medicine, the coating could be shellac, a natural resin and it said that it can be engineered to control the release time. It can be other resins or maybe cellulose related material too or other materials.
  5. A google search with catalyst + phase gets Phase-transfer catalyst ? so phase means solvent in chemistry ? <br>
  6. I'm thinking of becoming a farmer too. I've heard of several different liquid fertilizers. ah yes, I read that the farmers collect dried cow manure that has aged for a while, put into a pillow case and dump into a big container of water. and they use that water as fertilizer. They may aerate the water. Worm tea, which is the liquid that flows out of earthworm bin is said to be a good fertilizer. I used seaweed extracts and I'm quite impressed with the product. It can make the roots of orchids grow well. and for some plants, it makes them flowers just a few days to a week after application, but it is expensive though. If only I can replicate that. and there is a Urine and wood ash combination, which may have some research done by a university, don't know where is the paper , I have a rough idea of it only. The koreans picked several plants that grow wild and process them, like put into a pail of water to rot, and use the water as fertilizer. I've heard of that but don't know the details. <br>
  7. If you turn off the lights, it will be darkness inside the room. The material that is a red box, absorb other wavelengths and reflect red wavelength. so we see red. but If a person is colour-blind, he may see black colour. I think a red box still has the properties of a red box.
  8. Are you a girl ? How do you know he has Multiple-personality Disorder ? What are the symptoms or any unusual behavior ?
  9. Religion is soft power. just like any religion. Shariah law is an integral part of their religion. You can probably form a political party with a religious theme, at least in my part of the world. So by having enough people who are decidedly aligned to a faction, you can get the state to compromise, and have Religious laws as parallel or even an Islamic state. btw, Today is Hari Raya Haji. Happy holiday !

  12. "Adaptations such as fur color and beak length are established based on observation." The fox and some other animals have a winter coat. If I go to live at the arctic, my hair won't turn white though. I think those eskimos have dark colour hair. I kept some doves some years back. I think some doves may have slightly longer beaks, that they are born with. There are also variations in the size of the birds' heads and size of the feet of different birds, comparing same sex but from different nest. The beak is an organ that seem to be growing, like fingernails and sometimes become deformed when not used properly, like they should be pecking at the ground to even out the growth. I think the beak length is partly due to genes and partly due to how the birds use it. I would think evolution is random. As they say, if earth rewind the clock back and restart again, it may not come to the same conclusions again. and also if you think about a bird. I was like a bird trapper also. and there is this beautiful bird species. The most beautiful birds get to breed as usual, but if I trap the best birds, then the duller bird gets to breed. So the random factor is if I can catch the best bird or the dull bird, and whether it is a fine day or bad weather day, which may affect my decision to get out of the house.
  13. I guess you'll have to read a couple of basic articles about semiconductors and quote from them. Silicon is a semiconductor, and it is said to behave like something intermediate between conductors and insulators. If you look at the periodic table of elements, there are a bunch of elements there that are group near each other, silicon, geranium, arsenic ...and maybe carbon too, which the technology may be still in development. you may need to research the basic definition of semiconductor, I probably have missed out some parts. man...I don't know what the scientists think before, maybe someone else knows the history of it, or its inventor. Many years ago, the transistors or some other components/devices are very big size. It is a vacuum valve, which I forgot the actual name, It is still in use in some devices like maybe inside Hi-Fi speaker amplifiers. They made the earliest computer with these vacuum valves which make the computer very big size, maybe the size of one room. However the innovations with semiconductor solid state components replaced the vacuum valve, and made computers and electronic devices become smaller and smaller. OOPS!! I just realised that I made a huge mistake...LOL.. Superconductor ! not semiconductor... sorry about this, I would like to eat my own words.
  14. I find this wikipedia entry about coyote hybrids quite interesting... http://en.wikipedia....ki/Canid_hybrid I think it is a relatively gradual process. everything is constantly evolving, but the rates are not the same for each species. so the accumulated difference over thousands of generations may have make two species too far apart to be compatible. I've heard the coyote can eat a small dog. and the wolf will kill a coyote. There is a difference in inherent behaviors that they rarely produce hybrids. They are still capable of cross breeding, The cutoff is not very clear.
  15. 2. E&C and EEE and Electronics&Instrumentation What's E&C ? electrical and communication, or electronics and computer ? The usual course for electrical engineers is EEE, electrical and electronics engineering. which can probably cover many jobs. I think all the courses have many similar subjects or modules and branches out with a couple of special subjects. Some subjects are more in-depth. electrical and communication might be geared to some industries. Like telecommunications, operating satelite base stations or splicing fiber optics cables. and you might do jobs like networking, video linking , make devices at the factories, and such...maybe sound engineer who owns studios.. Electronics &Instrumentation, I think some jobs requires them, like power plants or energy companies. They are needed to maintain some Scada systems or something. and probably airline industry, or other utility companies. maybe even oil refineries or oil platforms, or chemical factories. but can apply for other jobs too. The jobs in electrical and electronics are varied. There are needs in biomedical as there are electronics in medical equipments, and is often linked to computers. Engineers and technicians are needed in the navies and airforces to work on the high tech weapons. There are demand in consumer products, so we make them at the factories. If there is semiconductor manufacturing around, they are needed to work on some silicon material , IC chip designing, and many jobs are in automation, in manufacturing. The cars and public transports have electronics device too. Robotics may need electronics and mechanical and is called mechatronics.
  16. Wow, you can write a lot ! Luckily, I've acquired the skill of selective reading. oh yes I've read the book by Richard milton. and I learnt that he is a harmless fruitcake from somewhere... I think in his own book or elsewhere. The clues of evolution is all around. The chihuahua is a dog, a poodle is a dog. Why they looked so different ? If you have cared to look and ask yourself. Don't look at the different birds in the forest, unless you are wallace . Try to think about domesticated animals or chickens, which may have some clues. There are obviously some doubts even for myself, like how to create a new species. and this I can't do it, but I've a clue somewhere. The one who create you is your father, and the other one before your father is your grandfather. This is definitely true. Know who's your real father is. It goes back further, you just call them your ancestors, and eh yes man created themselves. If you goes back alot further, the word "man" may be refering to another creature. The intelligent design is by man. One can make a designer dog and a designer bag.
  17. I guess it is about fungi , yeast or molds. you can state a few examples, and discus about them. examples are like foot fungus, or the molds that cause foodstuff, bread to go bad. or Candidiasis.
  18. I don't get it. In my opinion, both punctuated equilibrium and gradualism( relatively gradual ) seems to be the same thing. Darwin don't know about DNA in his days so it is more general, I don't find anything wrong. A doubt is that if the deduction is based on observing fossils, and also living organisms, but if the newer theories are also based on doing statistics on bones, well er ...there is no useful DNA in fossils, and they say that the geological records are imperfect. When drawing a graph, If you have two points, you get a straight line. If you have 3 or more points , you may get a slight curve. so with limited samples, you may get straight lines. The Ice age seems to be slow changes in environment over a long period. These are environmental changes which potentially affected creatures and plants. Right now we hear about global warming, and the polar bears are suffering. The change is very small, maybe 0.1units every decades or something. and it is not known if it will increase further or drop in future. I'm saying, there were drifts in environmental factors in the past. so creatures may have been constantly morphing to adapt to their environment or they die. and that is not the primary reason. There are several other reasons, chance, asteroids hiting earth causing a relatively abrupt changes. but generally, evolution seems to be a gradual slow process. The definition of species is also complex. Species is a man-made word for classification purposes. While that is usually the case, some varieties can have morphological difference that they look like different species from the main group. but it is hard for me to name some examples. maybe the asian arowanas which live on different islands. Some hybrid cichlids can probably cross the species gap, with man's assistance. and the natural hybrids of tropical pitcher plants and orchids. We know the living organisms are diverging , but the past records from fossils are not fully known.

    control!

    not a good reply earlier, so I edited it out.
  20. maybe...'fate' in philosophy and 'magical thinking' in psychology.
  21. I'm not a psychologist. Just to say, it sounds like it is not a serious problem. If you get depressed, you might need treatment. haha.. You can try to have open communication to sort out the misunderstanding , or if your school has a teacher or counselor who can advise you or her on how to deal with the problems free of charge. When I was a recruit in army, I faced adjustment problems, I got through it after a while. A few recruits who went to the medical doctors, got tagged with Adjustment disorder. When someone is not mixing well with their classmates, I think it could be adjustment problem. you can advice her to interact more often with her classsmates. The geeky and unattractive ones faced some problems sometimes. "but when they talk to her absurdly or get frank" ... If a girl is trying to talk to a guy, but if the guy is making fun of her, I guess it is normal for her to get out of the situation. but when she is not talking to her female classmates, that would be quite strange.. maybe the other female classmates are the bitchy types who spread rumours and such. I think you can encourage her to find some friends among her classmates, male or female ones. or try to know what is the situation right now. Pouring coke around is trying to get your attention. "she said you said to your friends that " i am mad" i said who,s that mad who have told you that you are mad? she said am i not mad? i said no, girl, you are beautiful and sweet. " .... "and then she ran away, smiling" ...... Well you said she was beautiful and sweet, so she ran away smiling. nothing unusual. Was she blushed ? She is like an angel, at 21 years of age, maybe a bit naive. or does she has a cute sense of humor? Its a harsh world sometimes, please guide her along. But if she has malicious intent, then you should protect yourself first. open communication... The above is just my opinion.
  22. I think it is fractional distillation. like oil refinery. wikipedia have it. You can tap out the hydrocarbons at 3 different parts of a column-like structure.
  23. qtrhorseluvr, you want to use the agar solution for what ? You probably will have a better picture reading up some articles at some websites, such as wikipedia, as you are looking for more complete information. Generally agar agar is a product extracted from seaweed. We eat it sometimes as dessert, with much sugar added, so it isn't a healthy dessert, but if we don't add sugar, it taste bland. Recipes can be found over at some websites. These are more practical than the useless experiments we amateurs do with it. It is said to be found at supermarkets that sell asian products, not sure about Japanese or Korean ones, this is usually chinese or South east asian ingredients. There are also carrageenan and Konnyaku at some places, carrageenan could be from another type of seaweed, and that Konnyaku is from a type of plant tuber. All of these stuff make jelly, but there is slight differences. Gelatine also makes jelly but is from animal or fish. These products may or may not be suitable for some applications. As I understand it, the agar is also used for culturing bacteria and growing plants with aseptic technique. The ones used for growing bacteria are specially made products, sometimes with other stuff added. There are several types for different applications. It is not found at supermarkets, but at Biomedical companies. I have not bought from them before, so I'm not sure about the details. Generally, we add the powder to water, which you can refer to the instructions to add how much, put in a pot and boil it until the water is boiling, after a short while, the agar will melt. You can pour into the petri dish or whatever jars or containers. When it cools down, it will solidify into a gel. Agar solution sounds strange...it is usually a gel, but if agar is use in lesser quantities, it does form a thick solution. I do not know what bacteria anyone will be culturing, but I think it may be dangerous, due to lack of knowledge in this field, so I wouldn't be doing any bacteria stuff. Those professionals do it at the labs, they know what they are doing. Another application of agar is for producing plants in labs. Plant nutrients and agar added together. There are several types such as Murashige and Skoog medium. I think some products have agar added, some without. These products are found at Biomedical companies, those dealing with plants stuff. It is used for growing orchids and tissue culture of plants for mass production, such as bananas. Maybe some years back, I was surfing some websites and came across someone DIY growing plants in flasks. I think that was cool, so I tried, and from my experience, I'm able to grow orchid seeds to seedlings about 2cm, after that they deteriorated, so more work needed, but it is possible to DIY. I do it with the grocery stores agar agar as the gel, and some other ingredients added. The techniques and recipes can be found at some websites, maybe google for it with words like "micropropagation" or "Kitchen tissue culture". but it is said that the commercial products of plant nutrient and agar are superior compared to DIY stuff. Tissue culture of plants is more complex, I can't do it yet, but maybe it is possible to DIY too. Need to beware of germs which often slips in the flask if not done properly.
  24. This could be due to sexual selection as said by Darwin, but some consider it the same as natural selection. Nyala, this antelope has horns, the females probably don't have, and the males are larger size. The horns may be used for display to intimidate other males, a larger pair of horns look more impressive. When it comes to real fight, bigger horns and bigger body usually wins. so the winner gets to mate. The advantage for the males would be it get to propagate more often. Many of the other ungulates shows sexual dimorphism, some species show more difference, while some show less difference.
  25. baking soda and vinegar , put in a bottle, stopper it, and shake it a bit.
