In any career, investing in your professional development is a valuable and necessary investment to make. For doctors and other medical practitioners this is equally true, if not more so. It is so important to keep up with new developments in your field, and for UK-based doctors and health consultants I have found one website that offers literally hundreds of options to improve your training and expertise. Oxford Medical offer a comprehensive consultant interview course that will have you handling interview situations like an experienced old hand. Fancy moving into the field of medical education? This is a massively growing sector with great career opportunities so why not take a medical teaching course? A teaching course like this is ideal for senior doctors and consultants who wish to add to their repertoire as educators as well as practitioners. Like any industry, as doctors move up the ranks they need to develop their leadership and management skills. Fortunately Oxford provide the option of taking a medical management course. This one is delivered by expert NHS doctors and managers and will add to your depth and skill-set when managing people within a medical environment. Still wishing to go further with medical education? You could always learn to train the trainer by studying a teach the teacher course, it could be the valuable next step in furthering your medical career. Good luck, and always be striving to improve!

The main reason as to why valves are placed on the water distribution system is to guide the flow of water within the water pipeline. The function served by the valves is also known as throttling. Throttling ensures that there is a steady stream of water along the set direction. Besides aiding the continuous flow of water, valves also regulate the flow of water by facilitating stoppage and beginning of water flow within the water pipeline.
In the event of a water break that is reported, the valve that is close to the water meter needs to be shut, and a plumber consulted promptly to remedy the situation. In the event of a pipe break, the valves that are close to the point of the breakage are often closed to create a subsystem isolation. Subsystem isolation ensures that there is minimal loss of water while rectifying the leakage that has been reported. The two main types of water system valves are water flow control valve and the stop and start water valves. Example water flows control valve and the stop and starts water valves are butterfly valve and the valve.
The first factor that affects the distinguishing nature of water is its physical characteristics. The freezing point of water is 00C while the boiling point of water is 1000C.
The second factor is the weight of water. A gallon of water weighs approximately 8 pounds, thus, making it relatively heavier and a prudent choice for use in putting off a fire.
Third, water has a high expansion, and a molecule of water expands more than 1000 times its size while at room temperature.
Fourth, water was a high heat absorbing capacity.
The first disadvantage that affirms why water should not be used as an extinguishing agent is the reaction that water may have with other forms of water (Sturzenbecker, Adams & Burnside, 2012). Water reacts with the combustible metals, thus, making it a risky component to use in extinguishing a fire. Additionally, water conducts electricity.
Second, water has a high surface tension and allows the radiant heat to pass through it, thus, making it a risky component. The major advantage of using water is its ease of accessibility and affordability. In many municipalities, water is often available freely (Sturzenbecker, Adams & Burnside, 2012). The cooling effect of water is relatively high and can serve to reduce the flames within a burning substance.
The first variable that directs influences the water piping distribution is the ability of the water pipeline networks is the safety of the water passing through the water distribution. The water distribution systems need to ensure that the water reaches the final consumer without any form of contamination and with the right chlorine content (Sturzenbecker, Adams & Burnside, 2012).
Second, the water piping distribution needs to take cognizance of the water demand within the locality and the different water uses and ensure that the allocation of water in a given region is responsive to the needs of the target consumers. The water-piping network needs to relay adequate water for domestic use, fire hydrants, recreation and any additional usage of water that is approved by the managers of a given locality. The third variable that directly influences the water piping distribution is the projection of population growth that is predicted within a particular region. The anticipated water flow needs to ensure that they take into consideration the water needs likely to arise owing to the population growth recorded in a locality.
