Primary prevention avoids the growth of a disease. Most population-based health support actions are primary preventive measures.Secondary prevention activities are intended at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and dipping disease-related complications.

USB Drives
0 commentsUSB flash drives offer possible advantages over other portable storage devices, particularly the floppy disk. They are more compact, generally faster, hold more data, and are more consistent than floppy disks. These types of drives use the USB mass storage standard, supported natively by recent operating systems such as Linux, Mac OS X, Unix, and Windows.

Wi-Fi
0 commentsA person with a Wi-Fi enabled mechanism such as a pc, cell phone or PDA can connect to the Internet when in proximity of an access point. The region enclosed by one or several access points is called a hotspot. Hotspots can range from a single room to many square miles of overlapping hotspots. Wi-Fi can also be used to create a mesh network. Both architectures are used in community networks.

Network Monitoring
0 commentsWhile an interruption detection system monitors a network for threats from the outside, a network monitoring system monitors the network for troubles due to overloaded and/or crashed servers, network connections or other devices.
usually measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to increase popularity.Status request failures, such as when a connection cannot be established, it times-out, or the document or message cannot be retrieved, usually produce an action from the monitoring system. These actions vary: an alarm may be sent out to the resident (SMS, email,...) sysadmin, automatic failover systems may be activated to remove the disturbed server from duty until it can be repaired, etcetera.Monitoring the performance of a network uplink is also known as network traffic measurement, and more software is listed there.

Hard Disk
0 commentsHard disks were initially developed for use with computers. In the 21st century, applications for hard disks have extended beyond computers to consist of digital video recorders, digital audio players, personal digital assistants, digital cameras, and video game consoles. In 2005 the first mobile phones to contain hard disks were introduced by Samsung Group and Nokia. The need for large-scale, reliable storage, independent of a particular device, led to the beginning of configurations such as RAID, hardware such as network attached storage (NAS) devices, and systems such as storage area networks (SANs) for efficient access to large volumes of data

Computer Networking
0 commentsA computer network is any set of computers connected to each other. Examples of networks are the Internet, a wide area network that is the largest to always exist, or a little home local area network (LAN) with two computers connected with standard networking cables connecting to a network interface card in each computer.

Robotics
0 commentsAlthough the exterior and capabilities of robots fluctuate enormously, all robots share the features of a mechanical, movable structure under some form of control. The chain is warped of links ,actuators and joints which can allow one or more degrees of freedom. Most contemporary robots use open serial chains in which each link connects the one before to the one after it. These robots are called serial robots and often resemble the human arm. A few robots, such as the Stewart platform, exploit closed parallel kinematic chains. Other structures, such as those that mimic the mechanical structure of humans, different animals and insects, are comparatively rare. However, the development and use of such structures in robots is an dynamic area of research. Robots used as manipulators have an end effector mounted on the last link. This end effector can be anything from a welding mechanism to a mechanical hand used to manipulate the environment.

Surgery
0 commentsSurgery is done to remove cancer cells and surrounding tissue. It is often combined with radiation therapy and chemotherapy. After surgery, the body needs extra calories and protein for wound healing and recovery. At this time, many people have some pain and fatigue. In addition, they may be unable to eat a normal diet because of surgery-related side effects. The body's ability to use nutrients may also be changed by removal of any part of the mouth, esophagus, stomach, small intestine, colon, or rectum.
Nutrition suggestions for people recovering from cancer surgery: If you've had surgery, remember that many side effects will go away within a few days of the operation. Certain drugs, self-care practices, and changes in diet can help lessen any side effects you may have. If they persist, be sure to tell your doctor, nurse, dietitian, or other member of your health care team.

Web blog
0 commentsBlogs are created with software that is easy to use (even for those who are not technologically savvy) and can be set up within minutes. Blogs are fun, are easy to use and allow you to voice your opinion online in real time. Maintaining a blog does not mean that you have to make daily updates; however, if you do not make at least somewhat regular updates, visitors will stop checking for new content.

The Lighthouse of Alexandria
0 commentsOf the Seven Wonders of the Ancient World, only one had a practical use in addition to its architectural elegance: The Lighthouse of Alexandria. For sailors, it ensured a safe return to the Great Harbor. For architects, it meant even more: it was the tallest building on Earth. And for scientists, it was the mysterious mirror that fascinated those most. The mirror which reflection could be seen more than 50 km (35 miles) off-shore.
On the ancient island of Pharos, now a promontory within the city of Alexandria in Egypt.
Shortly after the death of Alexander the Great, his commander Ptolemy Soter assumed power in Egypt. He had witnessed the founding of Alexandria, and established his capital there. Off of the city's coast lies a small island: Pharos. Its name, legend says, is a variation of Pharaoh's Island. The island was connected to the mainland by means of a dike - the Heptastadion - which gave the city a double harbor. And because of dangerous sailing conditions and flat coastline in the region, the construction of a lighthouse was necessary.

Home Decorations
0 comments
Art is often seen as belonging to one social class and excluding others. In this context, art is seen as a high-status activity associated with wealth, the ability to purchase art, and the leisure required to enjoy it. The palaces of Versailles or the Hermitage in St. Petersburg with their vast collections of art as home decorations, amassed by the fabulously wealthy royalty of Europe exemplify this view. Collecting such Vases is the preserve of the rich.
However, there is a tradition of artists bringing their vision down to earth, and inhabiting a mundane, even poverty stricken, world. The life of Vincent van Goth is a classic example of this starving artist tradition. It hardly needs to be mentioned, however, that few find such a state of existence desirable, and that one of the near-defining characteristics of artists is a desire to be seen universally, if not always to be understood. Picture Frames are used for home decorations.
Before the 13th century in Europe, artisans were considered to belong to a lower caste, since they were essentially manual laborers. After Europe was re-exposed to classical culture during the Renaissance, particularly in the nation states of what is now Italy, artists gained an association with high status. However, institutions of power as marks of their own status have always used arrangements of “fine” and expensive goods. This is seen in the 20th and 21st century by the commissioning or purchasing of art by big businesses and corporations as decoration for their offices.

Water Treatment Systems
0 commentsReverse osmosis systems, water filters, water treatment systems and distillers all promise sparkling, clean water, but how do you know which one is really best? With a little research, you can find the ideal water treatment system for you.
Water is vital to everyday life, and throughout history people have devised systems to make getting and using it more convenient. Water is treated to achieve water quality objectives for the end uses. In the case of potable water supply, water is treated to minimize risk of infectious disease transmittal, risk of non-infectious illness, and create a palatable water flavor.
Water treatment systems are designed and built to provide adequate water pressure, and flow rates to meet various end-user needs such as fire suppression, showering, and irrigation.

yachting
0 commentsWhilst there are many different types of racing vessels, they can generally be separated into the larger yachts, which are larger and contain facilities for extended voyages, and smaller harbor racing craft such as dinghies and skiffs.
Dinghy races are conducted on sheltered water on smaller craft, usually designed for crews of between one and three people. They are almost all equipped with one mast. Some have only one triangular sail, but most have two configured as a sloop, and usually carry a spinnaker, a large, bulging sail designed for sailing "with the wind".
