The process of forming a crystaline struture from a fluid or from materials dissolved in the fluid is often referred to as crystalization. In the ancient example referenced by the root meaning of the word crystal, water being cooled undergoes a phase change from liquid to solid beginning with small ice crystals that grow until they fuse, forming a polycrystalline structure. The physical properties of the ice depend on the size and arrangement of the individual crystals, or grains, and the same may be said of metals solidifying from a molten state.Which crystal structure the fluid will form depends on the chemistry of the fluid, the conditions under which it is being solidified, and also on the ambient pressure. While the cooling process usually results in the generation of a crystalline material, under certain conditions, the fluid may be frozen in a noncrystalline state. In most cases, this involves cooling the fluid so rapidly that atoms cannot travel to their lattice sites before they lose mobility. A noncrystalline material, which has no long-range order, is called an amorphous, vitreous, or glassy material. It is also often referred to as an amorphous solid, although there are distinct differences between solids and glasses: most notably, the process of forming a glass does not release the latent heat of fusion. For this reason, many scientists consider glassy materials to be viscous liquids rather than solids.

Eating a good breakfast will help you lose weight, decrease your risk for serious illness, and improve your concentration.
It keeps you slim: Breakfast eaters are less likely to be overweight than breakfast skippers, and successful dieters are also more likely to be breakfast eaters.
It keeps you healthy: Eating breakfast may reduce your risk of serious illnesses like heart disease, stroke, diabetes, and cancer, and it strengthens your immune system so you're more resistant to common ailments like colds and the flu.
It keeps you sharp: Memory and concentration get a boost from breakfast. A study on children found that kids who eat breakfast score higher on tests and are less likely to suffer from depression, anxiety, and hyperactivity. It should help you at the office, too.In the time you spend each morning calibrating your hair gel, you could be doing something more important, with a much better payoff: eating breakfast. Mom was right (and it's okay to admit it): Breakfast is the most important meal of the day. It is the perfect meal of the day.

It was my plan this week to go to the Red Cross office here to donate blood. So I went yesterday, but the lady there asked me what was my purpose of donating it seems that i looked scared when she said that it will take 5 minutes for it to be done. I told her I just want to donate and maybe it is a way to at least loose weight. She laughed and said that it might even make me fat it can boost appetite eating as to some people's experience. I started to doubt whether I will continue with it or not. She picked up sealed needle and cotton with alcohol and rubbed it at the tip of my ring finger. I closed my eyes I knew in few seconds she would hit it then I felt a little pain. She squeezed my finger and a little amount of blood dropped on the container that test my hemoglobin. I did not know what it contains it in. I dont know if I was lucky that the blood did not sink it means that i was not capable of donating blood because my hemoglobin was low. She smiled saying that i was not capable for the mean time maybe she thought that I would not lay and wait for 5 minutes having needle in my arm for the bag of blood that I have to donate. Frankly speaking "Yes" I am scared but I felt sorry too that I could not donate this time. I'm still not sure next time I wish I would be more brave and make sure that my hemoglobin is high. I need a lot of sleep and advised to eat those green and leafy vegetables that are rich in iron to add color to our blood. I would say sleep is really important for our health. I got a quote today that says:
Studies show that people who sleep between 6.5 hours and 7.5 hours a night, as they report, live the longest. And people who sleep 8 hours or more, or less than 6.5 hours, they don't live quite as long. There is just as much risk associated with sleeping too long as with sleeping . The big surprise is that long sleep seems to start at 8 hours. Sleeping 8.5 hours might really be a little worse than sleeping five
The recommended daily requirements should sound familiar: eight hours of sleep a night for adults and at least an hour more for adolescents. Yet 71% of American adults and 85% of teens do not get the suggested amount, to the detriment of body and mind. "Sleep is sort of like food," says Robert Stickgold, a cognitive neuroscientist at Harvard Medical School. But, he adds, there's one important difference: "You can be quite starved and still alive, and I think we appreciate how horrible that must be. But many of us live on the edge of sleep starvation and just accept it."
What most people don't realize is that the purpose of sleep may be more to rest the mind than to rest the body. Indeed, most of the benefits of eight hours' sleep seem to accrue to the brain: sleep helps consolidate memory, improve judgment, promote learning and concentration, boost mood, speed reaction time and sharpen problem solving and accuracy. According to Sonia Ancoli-Israel, a psychologist at the University of California at San Diego who has done extensive studies in the aging population, lack of sleep may even mimic the symptoms of dementia. In recent preliminary findings, she was able to improve cognitive function in patients with mild to moderate Alzheimer's simply by treating their underlying sleep disorder. "The need for sleep does not change a lot with age," says Ancoli-Israel, but often because of disruptive illnesses and the medications used to treat them.
May Help You Lose Weight
Researchers have also found that people who sleep less than seven hours per night are more likely to be overweight or obese. It is thought that the lack of sleep impacts the balance of hormones in the body that affect appetite. The hormones ghrelin and leptin, important for the regulation of appetite, have been found to be disrupted by lack of sleep. So if you are interested in controlling or losing weight, don't forget to pay attention to getting a good night's sleep.

We’re all guilty of overindulging sometimes—an extra helping of potatoes here, a wedge of key lime pie there. But loading up on calories forces your body into overdrive as it tries to deconstruct the damage.
“Just metabolizing food—especially fatty and carbohydrate-rich fare—causes the body to produce free radicals, which attack cells and can promote the development of chronic conditions including heart disease, diabetes and cancer,” says Ronald L. Prior, Ph.D., research chemist and nutritionist with the USDA at Arkansas Children’s Nutrition Center.
The more you consume, the more free radicals you produce. In fact, that’s one theory why caloric restriction—a practice of cutting calories by 25 to 30 percent—may protect against some disease. But recent research suggests that there are two ways to reduce free radicals: eating fewer calories and consuming more nutrient-rich fare, such as the following. (We suggest you do both.)

Sex and the City: The Movie (marketed as Sex and the City) is the romantic comedy feature film adaptation of the HBO comedy series Sex and the City (itself based on the book Sex and the City by Candace Bushnell) about four female friends living in New York City. The series often portrayed frank discussions about romance and sexuality.
Hi Girls... I watched this movie last day and from the very start to the end I kept my eyes opened and ears to listen every the dialogs casts will say. It was very nice and entertaining movie for me. I will just give you link for the summary of the story so that you will have an idea watching it. Enjoy watching..
