Reed Diffusers – An Explanation Of What They Are And How They Work
Reed Diffusers – An Explanation Of What They Are And How They Work
Article by Alex Muir
Reed Diffusers And How They WorkThe expression “home fragrances” is a relatively recent introduction to everyday language. It encompasses a variety of different products, the most well known of which – and certainly the most popular – is the scented candle. But you can also choose from room sprays, air fresheners, incense sticks and, increasingly commonly, reed diffusers. Diffusers are fast becoming a convenient alternative to scented candles, so we thought we would spend a few moments explaining a little about them to the uninitiated.So, what exactly is a reed diffuser? They are usually made up of three distinct elements: a bottle or container, scented oil, and the rattan reeds which distinguish the diffusers from other home fragrancing options. The bottles or containers are available in an assortment of shapes and sizes, from a simple clear jar to something much more ornate. The fragrant oil is placed in the jar, followed by the reeds. The oil travels up and through the reeds before being distributed throughout the surrounding atmosphere. The size of diffuser does not necessarily determine its potency, but you may very well choose a small diffuser in a bathroom whereas a reception room in a doctor’s office may require something larger to ensure the fragrance fills the entire room. Reed diffusers are easy to use. They are a safe, convenient alternative to candles as they do not require a flame to work and, once set up, are virtually maintenance free. To start using your diffuser, simply remove the packaging and set all the constituent parts on a flat surface. Then, uncap the bottle of oil and pour it into the empty jar or else simply uncap the container in which the oil is already housed. Then all you have to do is place the reeds into the filled container and enjoy the delightful aroma. The reeds have microscopic straw-like capillaries which when immersed in the oil soak it up and carry it along the whole reed. Please be aware that all reed diffusers are not the same. Put simply, when it comes to diffusers, as with scented candles, you get what you pay for. Premium quality scented candles and diffusers use high quality fragrant or essential oils which are obtained from plants, barks and other botanicals, meaning you receive a product which produces a natural subtle aroma which lasts much longer than cheaper alternatives made with synthetic fragrances. Another consideration is the reeds themselves. To work properly you must use rattan reeds which have the correct internal structure to allow the oil to diffuse properly. Cheap diffusers use wooden sticks which simply do not work and will leave you with a feeling of deep disappointment as well as empty pockets.Where can you use reed diffusers? Reed diffusers are perfect for using anywhere around the home, but because they do not rely on a flame to operate they are also eminently suitable for use in the workplace. At home they are perfect for using in reception areas to greet visitors with a lovely aroma as they enter your home, as well as in bathroom and, of course, the bedroom where diffusers with the natural fragrance of plants such as lavender or chamomile can help you relax and aid restful sleep.But basically, wherever you have a room, then you can use a reed diffuser. Shop owners use them to help create a pleasant and relaxing shopping experience. Reed diffusers can be found in waiting rooms of solicitors and dentists, where they can help clients relax. They are recommended by estate agents for use in the home before you have viewers over to inspect a house for sale. The list is virtually endless. Why not try one yourself today?

Question by bookworm: How to scanning electron microscopes and transmission electron microscope work?
i’m studying them in my science class, however the textbook is out of date and all the sites i’ve looked up give me various, different answers.
does anyone know a not too complicated way to explain how they work?

The old SEM i used in the 80′s, a bulb which high currents passes through, providing a high energy x-ray source. the chamber is vacuum of all air, and supercooled with liquid nitrogen. the x-rays pass through a series of magnetic rings to narrow the beam, which is rasped, (moved back and forth like the old TV’s CRT), of a specimen. the specimen must be made non-conductive, by sputter coating it with graphite or other materials. A SEM, gives us a good visual of the surface of a specimen, and when the specimen is hit with narrow focused electron beam between 100 and 300 thousand volts, it gives off secondary x rays, which are picked up by crystal detectors (EDXRA). these detectors can give counts of secondary x-ray wavelengths specific to elements. different type detectors can pick up different elements, because some wavelengths overlap. advantage, SEM can take a large specimen, sample may only may need little preparation,
without the vacuum, air molecules bounce the beam, and if too much air, it can have a arch of electrons like a bolt of lighting.

a TEM has much higher magnification, is designed to look through very thin specimens, to get not surface as a SEM does, but to look inside a cell for example, , and different type of analysis can be done, we used crystal diffraction, see crystal structure at atomic level on asbestos fibers. the advantage, very high magnification, can see inside specimen in 3-D, the drawback, it takes long time to get a sample to the level, thin enough, it can be looked at in a TEM

Why Is Organic Farming Bad – If It Is?
Why Is Organic Farming Bad – If It Is?
Why is organic farming bad, if it is? We have been told that organic farming is good for our health. Proponents have trumpeted the message that organic farming is good for the environment. How could it possibly be bad?
It seems that, increasingly, life is being divided into traditional and alternative. Each side claims their methods to be better than the other’s. Each tries to win people to their side. Traditional schooling fights alternative schooling. Conventional medicine fights alternative medicine. Mainstream culture fights alternative subcultures.
Farming, too, is involved in a battle, conventional farming against organic farming. Environmentalists and those concerned with their health assure us that organic farming is preferable in many ways. But others argue that organic farming is bad.
Why is organic farming bad?
Research Results
In 2002, Swiss scientists at the Research Institute for Organic Agriculture published in “Scientist” a highly publicized study. Their study, which covered 21 years, compared four types of farming. Two of those types were organic farming. The other two types were conventional farming.
Reporters quickly stated that the study proved organic farming was more efficient. Organic farming’s advocates said the study showed that organic farming uses 50% less energy. The facts?
1. Conventional farming is 20 percent more productive than organic farming.
2. Crop yields were significantly lower in organic farming.
3. The above two facts meant energy savings in organic farming were actually only about 19 percent per unit of crop produced, not 50 percent.
4. The study did not test organic farming against the most current methods of conventional farming. If it had, experts say, the 19 percent advantage of organic farming would disappear.
5. Current conventional farming matches organic farming when it comes to environmental advantages. Both have beneficial insects, produce less pesticide and fertilizer runoff, and reduce soil erosion.
6. Food quality was almost identical in conventional and organic farming. Advocates of organic farming had long claimed their food was far superior.
7. Current conventional farming methods produce the same or greater yields mentioned in number 1 above.
This research does not, of course, conclude that organic farming is bad. On the face of it, the conclusion is more that organic farming is not very different from current conventional farming. There most be other reasons for people believing organic farming is bad.
Organic Farming Can Kill
Many took from the Swiss study a realization that, as Cambridge chemist John Emsley said, “the greatest catastrophe the human race could face this century is not global warming, but a global conversion to ‘organic farming’- [where] an estimated 2 billion people would perish.”
Organic farming may supply food for small markets, but how can it feed starving nations? Its adversaries claim that current conventional farming is the only hope for these people. If we turn entirely to organic farming, they say, we will doom billions to die of starvation.
Challenging Organic Farming
Alex Avery, Director of Research and Education for the Hudson Institute’s Center for Global Food Issues, recently published a new book, “The Truth About Organic Foods.” (2006) In this book, Avery offers an unemotional look at the odd origins and unscientific basis for organic farming.
Nobel Peace Prize Winning Agricultural Scientist, Dr. Norman Borlaug, says about this book, “The Truth About Organic Foods gives consumers a thorough and straight-forward explanation of why organic foods offer no real health or safety benefits. More importantly, Avery communicates why organic farming’s lower yields and reliance on scarce organic fertilizers represents a potential threat to the world’s forests, wetlands and grasslands. The book offers scientifically sound evidence that more-affordable conventional foods are healthy for families and also good stewardship of nature.”
Skimming Mr. Avery’s book, one finds statements that indicate:
1. Organic farming started in the 1920s when a German mystic advised use of only animal manure because synthetic fertilizers had no cosmic energy.
2. Soon, the wealthy decided manure-fertilized produce was better.
3. J.I. Rodale first published his “Organic Gardening Magazine” in 1942, and the organic farming / organic gardening movement was named.
4. In 2007, organic farming advocates still have no credible science to support their beliefs.
5. Organic farming does not avoid pesticides. About 5 percent a vegetable’s weight is natural pesticides, some of which are cancer-causing.
6. Foods from organic farming have more illness-causing bacteria. (The January 2007 issue of “Consumer Reports” showed that chicken from organic farming has 300% more Salmonella than that from conventional farming. University studies have found more bacteria in vegetables from organic farming than in vegetables from conventional farming.
7. If organic farming, which decries synthetic fertilizer, was chosen over conventional farming, we would have a choice. We could kill millions of people to reduce global food needs, or we could sacrifice wildlife habitat in the amount of millions of square miles so we could produce more manure.
Why is organic farming bad? Mr. Avery believes he has the answer.
Notwithstanding Mr. Avery’s new book, I am not sure whether organic farming is bad or not. It is often difficult to sort through rhetoric and find fact. I do know that my forefathers had large organic farms. The produce was good and it was nourishing. Before I can turn my back completely on organic farming and organic gardening, I need clearer evidence. You probably want to do more research, too.
