Infrared
Infrared (IR) emission is electromagnetic emission of a wavelength longer than that of noticeable light, but shorter than that of radio waves. The name means "below red", red being the color of detectable light of longest wavelength. Infrared radiation spans three instructions of magnitude and has wavelengths between about 750 nm and 1 mm.
These divisions are suitable by the different human response to this radiation: near infrared is the area closest in wavelength to the radiation detectable by the human eye, mid and far infrared are gradually further from the visible regime. Other definitions follow different physical mechanisms and the newest follow technical reasons .Unfortunately the international standards for these specifications are not currently obtainable.
The boundary between visible and infrared light is not precisely defined. The human eye is markedly less responsive to light above 700 nm wavelength, so longer frequencies make irrelevant contributions to scenes illuminated by common light sources. But particularly strong light (e.g., from lasers, or from bright daylight with the visible light removed by colored gels can be detected up to approximately 780 nm, and will be apparent as red light. The onset of infrared is defined at different values typically between 700 nm and 780 nm.

Patrice Luzi
Patrice Luzi Bernardi is a French goalkeeper recently with Liverpool but released by the Anfield club in June 2005. He then signed a contract with Belgian side Mouscron.
Having previously played for Monaco and Ajaccio, Luzi made his Liverpool debut in January 2004 against Chelsea in a 1-0 win. He made two wonderful saves to deny Chelsea, but was left frustrated when he later was left out from the first team. His chances where limited when Liverpool loaned in Southampton's Paul Jones to cover from Jerzy Dudek and Chris Kirkland. Patrice Luzi has been described as a good shot stopper with good handling and distribution.
The SRBs are the largest solid-propellant motors ever flown and the first of such large rockets designed for reuse. Each is 149.16 feet long and 12.17 feet in diameter.

University
A university is an institution of higher education and research, which grants academic degrees at all levels bachelor, master, and doctorate in a variety of subjects. A university provides both tertiary and quaternary education. The word university is derived from the Latin universitas magistrorum et scholarium, roughly meaning community of masters and scholars.
Because of the above definition, there is some controversy regarding which is the world's oldest university. If we consider a university as a corporation of students, then Plato's Academy is the first historically documented university. The original Latin word "universitas", first used at the time of renewed interest in Classical Greek and Roman tradition, tried to reflect this feature of Academy. If we consider university simply as a higher education institution, then it could be Shangyang, which was founded before the 21st c. BC in China, if it is not a just myth. In the western world, the choice is between Takshashila, Nalanda, Ratnagiri University and Al-Azhar University.

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. So experts say washing hands frequently, specially when in an environment of many people with infections and diseases. 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:
• Use warm water
• But avoid scorching your hands.
• Use anti-bacterial soap or hand wash.
• Wash between fingers and use paper towels to wipe off.
Washing of hands has to be followed
• Before eating
• After eating
• After using the toilet
• After playing outdoor games
• After attending to a sick person
• After blowing nose, coughing, or sneezing; and after handling pets.
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.-healthy

common
• Daily washing of the body and hair.
• More frequent washing of hands and face.
• Oral hygiene—Daily brushing teeth.
• Cleaning of the clothes and living area.
• Use of bandaging and dressing of wounds.
• Not touching animals before eating.
• avoidance of unhygienic people.
• Holding a tissue in your hand when coughing or sneezeing.
• Suppression of habits such as spitting or nose-picking.
• Washing hands before eating.
• Not licking fingers before picking up sheets of paper.
• Cut finger nails and toe nails.
