RIS Delitti Imperfetti

RIS Delitti Imperfetti is an Italian television series, created in 2004 by Daniele Cesarano, Barbara Petronio and Leonardo Valenti, broadcast since January 2005 on Canale 5. The title, where RIS is an acronym for Reparto Investigazioni Scientifiche (an actual, real-life unit of the Carabinieri, the Italian gendarmerie), could be approximately translated into English as Unit of Scientific Investigations: Imperfect Crimes. As the title indicates, the series is a crime drama, focusing on the scientific aspects of crime investigations, in a similar vein as the popular American TV series CSI: Crime Scene Investigation (though RIS is not a remake thereof).

The Sixth season has been announced as being aired on Canale 5 every Thursday at 21:10 CET from January 2010.

Rail Integration System

Rail Interface System (RIS, sometimes also referred to as Rail Accessory System, RAS) is a generic term for a system for attaching accessories to small firearms such as pistols, rifles and light machine guns.

Common accessories include tactical lights, laser aiming modules, forward hand grips for improving weapon handling, telescopic sights for medium-ranged or distant targets, and reflex sights/red-dot sights for short to medium-ranged targets, iron sight lines, bipods, and bayonets.

Most RIS equipment is compatible with one or more of the most common rail systems, all of which are broadly similar:

These are used primarily in the military and by firearm enthusiasts to improve the usability of the weapon, being accessorized quickly and efficiently without requiring the operator to field-strip the weapon. Basic systems such as small rails (20mm is standard) with holes machined in them to be screwed onto the existing hand-guard of a rifle and can cost as little as US$25 to US$40. More advanced systems allow for numerous accessories to be mounted simultaneously and can cost upwards of US$200.

Zodiac

In both astrology and historical astronomy, the zodiac (Greek: ζῳδιακός, zōidiakos) is a circle of twelve 30° divisions of celestial longitude that are centered upon the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets also remain close to the ecliptic, within the belt of the zodiac, which extends 8-9° north or south of the ecliptic, as measured in celestial latitude. Because the divisions are regular, they do not correspond exactly to the boundaries of the twelve constellations after which they are named.

Historically, these twelve divisions are called signs. Essentially, the zodiac is a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude, and the position of the Sun at vernal equinox as the origin of longitude.

Usage

The zodiac was in use by the Roman era, based on concepts inherited by Hellenistic astronomy from Babylonian astronomy of the Chaldean period (mid-1st millennium BC), which, in turn, derived from an earlier system of lists of stars along the ecliptic. The construction of the zodiac is described in Ptolemy's vast 2nd century AD work, the Almagest.
