A well-balanced meal should contain all the macro-nutrients required for optimum health and to maintain the cells, tissues, and functions of the body.   These nutrients include protein, carbohydrate and a regulated amount of healthy unsaturated fat. Ideally, a well-balanced meal should It also includes a variety of vitamins and minerals. The importance of eating a well-balanced meal It is important to eat well balanced meals most of the time to ensure that your overall diet is also balanced, and that you are getting all the vitamins and minerals required for a healthy body.  Eating healthy, balanced meals will also provide you with plenty of long-lasting energy and keep you full for longer. Obviously, it is not always possible to eat a completely nutritionally balanced plate of food at every meal, but if you aim for a balanced the majority of the time, you will end up with a nutritionally complete diet overall. Try to ensure that each meal contains at least a  prote

These water valves are operated by handles.                                                        A valve is a device that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening closing or partially obstructing various passageways. Valves are Technically pipe fittings. But are usually discussed as a rate category In an open valves Fluid flows in a direction from higher pressure to lower pressure. Valves are also found in the Human body. For example, several heart valves control the flow of blood in the chambers of the heart and maintain the correct pumping action. Valves are used in a variety of contexts, including industrial, military, commercial Residential, and transportation. The industries in which the majority of valves are used are oil and gas. Power generation, mining, water reticulation. Sewerage and Chemical Manufacturing.Plumbing valves, such as taps for hot and cold tap water are the most Noticeable types of valves. Other

An electric motor is a motor that uses electrical energy to produce mechanical energy, usually through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy is accomplished by a generator or dynamo. Traction motors used on vehicles often perform both tasks. Electric motors can be run as generators and vice versa, although this is not always arctic Electric motors are ubiquitous, being found in applications as diverse as industrial fons blowers and pumps, machine tools, household appliances, power tools, and disk drives They may be powered by direct current (for example a battery powered portable device or motor vehicle) or by alternating current from a central electrical distribution grid. The smallest motors may be found in an electric wristwatch. Medium-size motors of Highly standardized dimensions and characteristics provide convenient mechanical power for industri

In the wilds of its native habitat, the Sugar Glider Sugar Bear is a tree-dwelling creature, often living in groups of ten to fifteen. It is active at night when it hunts for small vertebrae and insects. It feeds on the sweet sap of certain species of eucalyptus, acacia and gum trees. The Sugar Glider Sugar Bear is named for its preference for sweet foods and its ability to glide through the air like a flying squirrel. It lives in groups of up to seven adults, plus the current season's young, all sharing a nest and defending their territory, an example of helping at the nest. Adult males mark the territory with saliva and with a scent produced by glands on the forehead and chest, and also mark members of the group with this scent. Visitors who lack the appropriate scent marking are expelled swiftly, even violently. The dominant male mates more frequently with the female of the group than the other males. When an adult member of the group dies, it is normally replaced by

SENSORS Automatic control systems several parameters such as tem nature, light, level, proximity, Limit are to be sensed and conveyed to a control devise for the purpose of output control The above parameters are generally sensed by different devices l as sensors. Those sensors give appropriate signals to the rol device. The device picks up the signal from those devices to check the condition of the system on receiving the input. The aut signals given by the sensors are passed to the control device in terms of ON-OFF logic signals Sensors are detectors that can measure some type of physical quality that is happening, such as pressure or light. The sensor will then be able to convert the measurement into a signal that one will be able to read. Most of the sensors in use today are actually going to be able to communicate with an electronic device that is going to be doing the measuring and recording. Today, you are going to be able to find sensors in a wide range o

Turtles, once you get them home and into their tanks, require very little personal turtle care. As long as their turtle tanks are kept clean, they are very low maintenance creatures, pretty much a step above fish when it comes to personal attention. While other pets like dogs and cats require a lot of time and effort, turtles thrive when they are left to their own devices (though some turtles have been known to show preference to certain people and some can even be taught to follow simple commands). The most important part of turtle care is the turtle tank. The best turtle tanks are tanks that are set up outside, in the turtle's natural habitat—building a little area for your turtles in your yard is often one of the best ways to take care of them, assuming your yard is free of natural predators and environmental concerns (if you use pesticides on your plants, for example, keeping your turtle outside might not be such a good idea). The main reason to keep your turtle outsi

The Different Types of Turtles: There are hundreds of different types of turtles. This article aims to give you a brief overview of the different types of turtles. Here is a shortlist of some of the types of turtle The Pig Nosed Turtle: This type of turtle has been called the Australasian Pig-nose turtle, the pitted shelled turtle, the plateless turtle, and even the fly river turtle. This kind of turtle is soft-shelled and is usually found in freshwater rivers, lagoons, and streams in Australia's Northern Territory and in New Guinea.  The Green Sea Turtle:  This family of a turtle is rather large and can be found in most subtropical and tropical areas in the world. It has two very distinct populations in the Pacific Ocean and The Atlantic Ocean. This is an endangered species and it is illegal to harm, kill or collect them.  The Alligator Snapping Turtle:  T
