Space Shuttle Solid Rocket Booster

The Space Shuttle Solid Rocket Booster is the rocket that provides 83% of liftoff thrust for the Space Shuttle. It is the major and most powerful solid rocket ever flown, and the most powerful rocket motor of any type ever flown. Each SRB produces 1.8 times the liftoff thrust of the F-1 engine used in the Saturn V moon rocket.
The two reusable SRBs provide the main thrust to lift the Space Shuttle off the pad and up to an altitude of about 150,000 feet . In addition, the two SRBs carry the whole weight of the external tank and orbiter and transmit the weight load through their structure to the mobile launcher platform. Each booster has a liftoff thrust of approximately 2,800,000 lbf at launch. They are ignited after the three space shuttle main engines' thrust level is verified. The two SRBs provide 83 % of the thrust at lift-off. Seventy five seconds after SRB separation, SRB apogee occurs at an altitude of approximately 220,000 feet , after which they land on parachutes; impact occurs in the ocean approximately 122 nautical miles downrange, after which the two are recovered.

Penguins

Penguins are excellently adapted to an aquatic life. Their wings have grow to be flippers, useless for flight in the air. In the water, however, penguins are astonishingly agile. Within the soft plumage a layer of air is preserved, ensuring buoyancy. The air layer also helps protect the birds in cold waters. On land, penguins use their tails and wings to maintain balance for their upright stance.
All penguins are counter shaded - that is, they have a white underside and a dark (mostly black) upperside. This is for camouflage. A predator looking up from below (such as an orca or a leopard seal) has difficulty distinctive between a white penguin belly and the reflective water surface. The dark plumage on their backs camouflages them from over.
Diving penguins reach 6 to 12 km/h (3.7 to 7.5 mph), although there are information of velocities of 27 km/h (17 mph) (which are more practical in the case of startled flight). The small penguins do not generally dive deep; they catch their prey near the surface in dives that normally last only one or two minutes. Larger penguins can dive deep in case of need. Dives of the large Emperor Penguin have been recorded which get to a depth of 565 m (1870 ft) and last up to 20 minutes.
Penguins either waddle on their feet or slide on their bellies across the snow, a movement called "tobogganing", which allows them to keep energy and move fairly fast at the same time.Penguins have an superb sense of hearing. Their eyes are personalized for underwater vision, and are their primary means of locating prey and avoiding predators; in air, equally, they are nearsighted. Their common sense of smell has not been researched so far.They are able to drink salt water securely because their supraorbital gland filters excess salt from the bloodstreamThe salt is excreted in a concentrated fluid from the nasal passages.

Food

Many plants or plant parts are eaten as food. There are around two thousand plant varieties which are cultivated for food, and many have several distinct cultivars.Plant-based foods can be classified as follows: Seeds, the ripened ovules of some plants, carry a plant embryo inside them along with the nutrients necessary for the plant's initial growth. Because of this, seeds are often packed with energy, and are good sources of food for animals, including humans. In fact, the majority of all foods consumed by human beings are seeds. These include cereals (such as maize, wheat, and rice), legumes (such as beans, peas, and lentils), and nuts. Oilseeds are often pressed to produce rich oils, including sunflower, rape (including canola oil).Fruits are the ripened extensions of plants, together with the seeds within. Fruits are made attractive to animals so that animals will eat the fruits and excrete the seeds over long distances. Fruits, therefore, make up a significant part of the diets of most cultures. Some fruits, such as pumpkin and eggplant, are eaten as vegetables.Vegetables are other plant matter which is eaten as food. These include root vegetables (such as potatoes and carrots), leaf vegetables (such as spinach and lettuce), stem vegetables (such as bamboo shoots and asparagus), and inflorescence vegetables .Many herbs and spices are highly-flavorful vegetables.

Essentials of healthy life-cleanliness a brief review

Health is wealth so preserve it. Life is short so use it in the right way. Cleanliness merely fits with the apt meaning of being free from dirt, dust, germs and bad smells. A recent shift has now taken place to recognise that 'germs' may play a major role in our immune systems.

Washing is one of the best way to achieve cleanliness.Have a brief overlook on the following issue to be aware of how to keep one self clean.
A step way process regarding cleanliness of hands is given below:

The proverb "Cleanliness is next to Godliness," a common phrase that describes humanity's high opinion of being clean. Purposes of cleanliness include health, beauty and to avoid the spreading of germs .If your hands have any kind of skin cut or infection, wash hands with an anti bacterial soap. Thoroughly wash with hot, soapy water all surfaces that come in contact with raw meat, poultry, fish, and eggs before moving on to the next step in food preparation. Consider using paper towels to clean kitchen surfaces.Keep pets, household cleaners, and other chemicals away from food and surfaces used for food. Along with removing any old food or dirty water, it's a very good practice to clean the bowls or containers that the food and water are in, ever Hygienic practices—such as frequent hand washing or the use of boiled (and thus sterilized) water have a profound impact on reducing the spread of disease. This is because they kill or remove disease-causing microbes (germs) in the immediate surroundings. For instance, washing one's hands after using the toilet and before handling food reduces the chance of spreading E. coli bacteria and Hepatitis A, both of which are spread from fecal contamination of food.-healthyPersonal cleanliness:sadblack1 common
