Aquarium

The aquarium has a long history and maintaining an aquarium has become immensely popular worldwide. Aquaria can come in a variety of materials, shapes, and sizes. They are classically constructed of glass or high-strength plastic. Cuboid aquaria are also known as fish tanks or simply tanks, while bowl-shaped aquaria are also known as fish bowls. Size can range from a small glass bowl to enormous public aquaria. A number of apparatus are used to maintain appropriate water quality and uniqueness suitable for the aquarium's residents. There are many types of aquaria, classified by the organisms maintained or the type of surroundings that is mimicked.

Health

Health is the intensity of functional and metabolic effectiveness of an organism at both the cellular and macro social level. In the medical field, health is generally defined as an organism's aptitude to efficiently respond to challenges and effectively restore and maintain a "state of balance," known as homeostasis.

A rising measure of the health of populations is height, which is powerfully regulated by nutrition and health care, among other set of living and quality of life matters. The lessons of human growth, its regulators and its implications are known as auxology.

Wellness is a word sometimes used to describe the psychological position of being healthy, but is most frequently used in the field of alternative medicine to describe one's state of being.

Cooking

Cooking is the act of preparing food for eating. The term cooking encompasses all methods of food preparation with non-heated methods. It encompasses a huge range of methods, tools and combinations of ingredients to change the taste or digestibility of food. It is the method of select, measuring and combining of ingredients in an planned procedure in an try to get the desired result. Factors affecting the finishing outcome include the inconsistency of ingredients, ambient conditions, tools, and the skill of the person doing the actual cooking.

The variety of cooking universal is a reflection of the many nutritional, aesthetic, agricultural, cultural and religious considerations that crash upon it.

Cooking frequently requires applying heat to a food, which regularly, though not always, chemically transforms it, thus varying its flavor, texture, appearance, and nutritional properties. There is archaeological proof of roasted foodstuffs, both animal and vegetable, in human campsites dating from the initial known use of fire, some 800,000 years ago.

Electrostatic induction theory

Another theory is that opposite charges are driven apart by the above mechanism and power is stored in the electric field between them. Cloud electrification appears to necessitate strong updrafts which hold water droplets upward, supercooling them to -10 to -20 C. These have a collision with ice crystals to form a soft ice-water mixture called graupel. The collisions result in a slight positive charge being transferred to ice crystals, and a slight negative charge to the graupel. Updrafts drive lighter ice crystals upwards, causing the cloud top to accumulate increasing positive charge. The heavier negatively charged graupel falls towards the middle and lower portions of the cloud, building up an increasing negative charge. Charge separation and accumulation continue until the electrical potential becomes sufficient to initiate lightning discharges, which occurs when the gathering of positive and negative charges forms a adequately strong electric field.
