Tissue macerating instrument
A surgical tissue macerating and removal tool is described which has a rotating rod with a cutting member at one end and which disposed in a tube which is then contained in an extension of the tool handle. A frusto-conical member extends into the extension at the cutter member end of the rotating rod with its small end engaging the tube. The portion of the frusto-conical member outside of the extension forms a tissue engaging member and may be cut-off at an angle to the axis of the rod to form a tissue engaging edge. Apertures are provided in the extension adjacent the frusto-concial member so that treatment fluid supplied in the annular space between the tube and the extension may flow to the operative site. An aperture is provided in the frustoconical member between the extension and the tube so that fluid may also flow into the tube where it mixes with macerated tissue being directed through an aperture in the tube to a passageway which may have suction applied to help remove macerated material

Quantum Walks with Entangled Coins
We present a mathematical formalism for the description of unrestricted
quantum walks with entangled coins and one walker. The numerical behaviour of
such walks is examined when using a Bell state as the initial coin state, two
different coin operators, two different shift operators, and one walker. We
compare and contrast the performance of these quantum walks with that of a
classical random walk consisting of one walker and two maximally correlated
coins as well as quantum walks with coins sharing different degrees of
entanglement.
We illustrate that the behaviour of our walk with entangled coins can be very
different in comparison to the usual quantum walk with a single coin. We also
demonstrate that simply by changing the shift operator, we can generate widely
different distributions. We also compare the behaviour of quantum walks with
maximally entangled coins with that of quantum walks with non-entangled coins.
Finally, we show that the use of different shift operators on 2 and 3 qubit
coins leads to different position probability distributions in 1 and 2
dimensional graphs.Comment: Two new sections and several changes from referees' comments. 12

It\u27s Elementary, My Dear Lawyer : Use Online Investigative Resources
The web is a handy investigative tool, allowing a researcher to obtain a variety of information about persons, property and things. One can find email addresses, home addresses, telephone numbers, criminal records, military service information, property records, vital statistics information, photographs and more. This information may help locate a missing heir, reveal useful information about a potential expert witness, confirm the legitimacy of a business, determine who owns a piece of property or expose the litigious nature of a potential client

From Attorney to Detective: Using the Web as an Investigative Tool
The web is a handy investigative tool, allowing a researcher to obtain some kinds of information previously requiring the services of a private detective. One can find a subject\u27s email address, home address, telephone number, criminal records, property records, vital statistics information, and more. Much of the information is free, but considerably more is available for a fee. Most of the sites providing free information heavily promote paid services that provide more extensive information. The vast number of sites providing access to information about persons, property and things makes it impossible to provide an inclusive list; therefore, this chapter strives only to provide a sampling of representative sites
Web in a Whirlwind: 30 Sites in 30 Minutes
Most of the sites listed within are law-related; however, the usefulness for legal professionals of a few non-legal sites warrants their inclusion. In addition, a couple of the list sites address hot topics and are included for that reason. Finally, since everybody deserves a little relaxation and humor, the list contains a couple of fun sites
