宠物-床Drinking a Cup of Coffee Everyday?

I simply enjoy my coffee in the mornings... I do not think of it as an energy boost. If that's what you are feeling, be careful. If you are addicted to a chemical, that's never a good thing. But I would not worry about your system becoming immuned to the benefits you get from the caffeine. But do not over-think it, or you could start actually believe it, and increasing your caffeine intake, eventually leading to more serious healthy problems. You might want to think about what else can energize you in the mornings. . like exercise, a good, healthy breakfast, not to mention a good night's sleep (chemical free)

1. Will a tall narrow cup keep a cup coffee warmer than a more evenly dimensioned cup?

In general, yes, for a given volume a sphere has the least surface area and therefore the least heat loss to the environment.But we have the complication that the top of the vessel must be open and uninsulated.For a fixed temperature of the liquid and the ambient air, a simple model would say the three types of surfaces on a cylinder each have a fixed heat flux (power per unit area). Say these are $q_mathrmtop$, $q_mathrmbottom$, and $q_mathrmside$. The total energy per unit time lost to the environment is $$ Q = pi r^2 (q_mathrmtop q_mathrmbottom) 2pi rh q_mathrmside $$ for a cylinder of radius $r$ and height $h$. If we fix the volume $V$ as a constraint, then $pi r^2h = V$, so we have $$ Q = pi r^2 (q_mathrmtop q_mathrmbottom) frac2Vr q_mathrmside. $$The optimal container has as its radius the $r$ that minimizes $Q$. This occurs for $$ 0 = fracmathrmdQmathrmdr = 2pi r (q_mathrmtop q_mathrmbottom) - frac2Vr^2 q_mathrmside, $$ or $$ r = left(fracVq_mathrmsidepi(q_mathrmtopq_mathrmbottom)

ight)^1/3. $$Qualitatively, we can note a few things. For instance, the ideal radius grows proportional to the cube root of the desired volume, which is not unexpected. In fact, for fixed $q$'s, the ideal container simply scales with $V$ - it's shape does not change.Moreover the ideal container in this model is neither too wide nor too narrow. Too wide, and the $pi r^2 (q_mathrmtop q_mathrmbottom)$ term means all the heat is lost through the top (and bottom), while too narrow and the $(2V/r) q_mathrmside$ term becomes larger than it needs to be.I do not have an actual number, though, because I do not know the values for the $q$'s. One could presumably look up the properties of the ceramic involved for $q_mathrmbottom$ and $q_mathrmside$. Even then, though, I treat these terms separately because they could depend on the shape of the vessel: the sides will be more efficiently cooled by convection than the bottom, unless the cylinder is very narrow. On top of this, the heat transfer through the top needs to be modeled, and that itself is a difficult fluid dynamics problem.

2. I am thin I want put on weight. so please tell the solution.?

Hi, Tips for weight Gain Weight gain: eating plan Firstly, eliminate all the causes of underweight. Make sure that you do not suffer from underlying illnesses that cause weight loss or hamper weight gain and that other important factors such as medications, depression, or anxiety are not preventing you from gaining weight. If you have a clean bill of physical and mental health, the solution to underweight is to ingest more energy on a daily basis than you use up for physiological processes and physical activity. This means that you must eat more at each meal and have healthy snacks between meals. If necessary, take a meal supplement like Ensure or Fresubin with fibre or one of the Nestle products such as Nutren Fibre between meals every day. High-energy diet for the underweight Here is an example of a diet that will provide you with sufficient energy to assist with weight gain: Foods that should be included every day: Full-cream milk: 750 - 1000 ml (3 to 4 cups) Meat, fish, eggs and other protein foods: 3-5 servings (90 to 150 g) Bread and cereals: 8-12 servings (e.g. up to 6 cups of starch a day) Fruit and vegetables: 3-5 servings Fats and oils: 90 g (6 tablespoons) Healthy desserts: 1-2 servings Menu Before breakfast: 1 cup of tea or coffee with full-cream milk, 2 t of sugar and 2 biscuits Breakfast: Fruit or fruit juice (1 orange or 1 glass of orange juice) Cereal with milk and sugar (1/2 cup of breakfast cereal or porridge, with cup of full-cream milk and 2 t of sugar or honey, or 1 tablespoon of raisins) Boiled egg or bacon or sausage (fry bacon or sausage in non-stick pan) Wholewheat toast or roll with butter and jam (1-2 slices of toast or rolls with 30g polyunsaturated margarine and 1-2 tablespoons of jam, honey or marmalade) Beverage (1 cup of coffee or tea with full-cream milk and 2 t of sugar) Morning tea: Milky drink (cappuccino made with cup of full-cream milk and 2 t sugar) or Smoothy (process full-cream milk with fruit and honey in 1 glass - see recipe tips below) or Fruit juice with snack (1 glass of fruit juice with 30 g peanuts or dried fruit or an energy bar) Lunch: Soup (1/2 cup) Meat, fish or poultry (120 g portion) Potato (1 large potato or sweet potato, or rice or pasta) Vegetable or salad with dressing (1/2 cup of cooked vegetables or cup of salad with 1 T of salad dressing or mayonnaise) Pudding (1/2 cup of boiled, sweetened or canned fruit with 1 scoop of ice cream or cup of custard) Roll with butter and cheese (1 whole-wheat roll or 2-3 whole-wheat biscuits with 2 t polyunsaturated margarine and 30g of cheese) Beverage (1 cup of coffee or tea with full-cream milk and 2 t of sugar) Afternoon tea: Sandwiches with filling (2 slices of whole-wheat bread with 2 t polyunsaturated margarine and 2 T peanut butter or cream cheese with chopped nuts or egg mayonnaise) or Cake or biscuits (1 slice of cheese cake or 2-3 chocolate digestive biscuits) Tea with milk and sugar (1 cup of tea with full-cream milk and 2 t of sugar) Supper: Fruit juice (1 glass) Meat or fish or cheese or eggs (90 g portion or 1-2 eggs) Vegetable or salad with dressing (1/2 cup of cooked vegetables or cup of salad with 1 T of salad dressing or mayonnaise) Starch (1/2 cup of cooked rice or pasta or potato) Pudding (1/2 cup of rice or tapioca pudding or ready-to eat puddings or 2 scoops of ice cream) Beverage (1 cup of coffee or tea with full-cream milk and 2 t of sugar) Bedtime: Milk drink (1 cup of Milo or Ovaltine made with full-cream milk) Biscuits (2-3 biscuits) Nutrient composition The diet outlined above should provide 12 600 to 14 700 kJ or 3000 to 3500 cal a day, and 100 to 120 g of protein. All other nutrients are provided. It is estimated that a person eating this diet would gain 1 to 1,5 kg per week. Tips for making smoothies To make delicious smoothies, use the following: 1-2 fruits (peeled apples or mashed bananas, mixed with 1 T of lemon juice to prevent fruit from discolouring, or apricots, mangoes or fresh berries, or any other fruit in season) 1 cup of full-cream milk 2 T whole-milk powder 2 t sugar or honey Place ingredients in blender. Blend till smooth and serve ice cold. My favourite smoothy: 1 ripe avocado (peel, remove pip and mash with 1 T lemon juice to prevent discolouration) 1 cup of full-cream milk 2 t honey Place ingredients in blender. Blend till smooth, chill till ice cold and serve with a pinch of nutmeg on top.

3. what's the difference between a wii cup and a retro cup..?

yeah retro cups are from other nintendos going all the way back to NES, SNES, N64, Game BOy Advance, and Game Cube...some might be from DS too... ther Wii Cups are all brand new
