Iris need to be thinned or divided before they become overcrowded, generally every 3-4 years. If iris are allowed to become too crowded the bloom will suffer, some varieties may crowd others out and disease problems may be aggravated. Old clumps may be thinned by removing the old divisions at the centers of the clumps and leaving new growth in the ground. Or, you may dig up the entire clump and remove and replant the large new rhizomes.

The iris is the coloured muscle around the pupil, which regulates the amount of light entering the eye. For more information, please see link.

Iris recognition biometric technology positively determines the identity of an individual by capturing a high resolution digital photograph of the individual's iris. The technology is based on the most mathematically unique biometric -- even between twins or an individual's right and left eyes -- the iris of the eye. The technology is non-intrusive - the individual does not need to touch anything to use the system.

Iris recognition is proven to have the highest biometric accuracy, with no false matches in over two million cross-comparisons, according to Biometric Product Testing Final Report March 2001, Center for Mathematics and Scientific Computing, National Physics Laboratory, U.K.). The human iris is absolutely unique, even between twins or an individual's right and left eyes. The iris itself is stable throughout a person's life (approximately from the age of one).

These are rare tumors. They can be either primary tumors of the iris (e.g. malignant melanoma) or spread from another tumor (e.g. breast, lung). Treatment of these tumors depends on whether the tumor is growing and also whether there is any complication from the tumor (e.g. uncontrolled glaucoma). In the case of glaucoma that does not get better with medication, or if the tumor is growing quickly, it may be necessary to remove the entire eye.

Iris recognition technology is strictly voluntary – just as it is now with any identification card kits that may be used with children. Participants agree to enroll, thereby eliminating privacy concerns. The user voluntarily decides to participate in iris recognition for authentication by looking at a digital video camera from about 5 – 10 inches away from the camera. The technology cannot work without the explicit cooperation of the end-user.

Many Sheriffs are already using iris recognition as an integral part of their arrest, booking, intake, and release process. Roll out of the The Child Project™ application began in January of 2005. During the initial phase of the program, The Child Project™ contacted Sheriffs to gauge their interest in participating in the program.

Iris come in every color and tone with the exception of true red. Throughout the catalog you will find detailed descriptions which attempt to convey a mind's eye image of the flower to go along with the picture of the flower. It can be very difficult to describe the complex color blending that takes place in nature, so you may sometimes disagree with a description or question whether it is accurate or matches the picture.

In addition to color, iris may be categorized by flower pattern, form, texture, substance, variegation, season of bloom and American Iris Society awards received. The following terms are used to describe iris: Yellow or near yellow standards with deeper falls which may be either varied or solid tones of brown or purple.

For best results, iris should be planted in July, August or September. It's imperative that the roots of newly planted iris be well-established before the growing season ends. In areas with hot summers and mild winters, September or October planting may be preferred.

Newly set plants need moisture to help their root systems become established. Specific watering information depends on your climate and your soil, but keep in mind that deep watering at long intervals is better than more frequent shallow waterings. Once established, iris normally don't need to be watered except in arid areas. Overwatering is a common error.

Specific fertilizer recommendations depend on your soil type, but bone meal, superphosphate and 6-10-10 are all effective. A light application in the early spring and a second light application about a month after bloom will reward you with good growth and bloom. Avoid using anything high in nitrogen, as nitrogen encourages rot problems.

iris NextBus is our latest iris service and it offers bus arrival time estimation on a real time basis. You now have the convenience of knowing how many minutes away your bus is from your bus stop or how long more before the next bus departs from the bus interchange. iris NextBus is available on our website as well as via GPRS and sms on mobile devices.

The iris illustrates the whole person, including the whole body and the whole mind. Individual traits are identified at two levels, static and dynamic. The static traits are the constitutional qualities as shown by the overall structure and color of the iris, and the dynamic traits are indicated by small changes in the iris during the person's life. More advanced methods can be applied for identifying the past chronology of accumulated iris markings.

Each part of the whole body contains information on all parts of the body. This is true for all forms of life, at the level of genetic encoding for metabolic processes, cellular respiration, and tissue generation. For example cutting off some trimmings from a Geranium bush and sticking the branches into the ground triggers a differentiation process, changing the cut end into a root system and produces a new Geranium bushes.

Extensive research has been undertaken into the accuracy, stability and convenience of different biometric devices. Research supports iris biometric devices as being the most accurate, stable, most difficult (almost impossible) to fool, the most convenient/hygienic and non-evasive. The iris cannot be forged in the same way as a fingerprint (fingerprint marks can be left behind and duplicated, but the iris leaves no mark).

The system has both advantages and disadvantages to electronic fingerprint systems, such as Live Scan. Here are some of the advantages: the iris biometric is about 12 times more unique --- from a science and statistical perspective -- than fingerprint biometrics. There is no need to touch anything (as with fingerprint) to capture the biometric data. A participant simply looks at a digital camera from about 10" to 15" inches and it takes a digital photo of their iris.
