Collector’s items

October 11 The venerable Colt firearms company announces that it will no longer sell handguns to consumers, except as collector s items. The company is believed to have acted to reduce its potential liability in future lawsuits and because fear of lawsuits has begun to drive suppliers, lenders, and investors from the consumer firearms market. 

Their policies range from the permissive (all law-abiding adults) to the highly restrictive (must show a definite need), cop-killer bullet Term for armor-piercing ammunition popularized by gun control advocates. The term gets its name on the basis that it especially endangers police wearing bullet-proof vests, curios and relics Firearms that are at least 50 years old or that are considered (because of their scarcity, historical value, or unusual nature) to be collector s items. A federal firearms license (FFL) is required for interstate purchase of such firearms. 

The United States established its first mint to make silver and gold coins in Philadelphia in 1792. Some of these old gold and silver coins have become quite valuable as collector s items. An 1804 silver dollar recently sold for more than 4 million. A silver dollar is actually 90% silver and 10% copper. Because the pure elements gold and silver are too soft to be used alone in coins, other metals are mixed with them to add strength and durability. These metals include platinum, copper, zinc, and nickel. Metals make up the majority of the elements in the periodic table. 

He described it as a very remarkable red lead mineral which has never been found in any other mine. When pulverised, it gives a handsome yellow guhr which could be used in miniature painting. Chromium from the Beresof Mines and Siberia was used as a paint pigment. Due to its rarity, this later became a collector s item and increased in popularity in the paint industry. A bright yellow made from crocoite fast became the fashionable color for the carriages of the nobility in both France and England. 

Although some remarkably striking gemstones can be cut from phosphate minerals (Chapter 2), these minerals have usually been listed as less well known or as collector s items . In some cases, limitations as gemstones arise from fragility or insufficient hardness. The best known of these gan-stone phosphates is turquoise (Table 5.23). 

Figures 9.5 and 9.6 show examples of monitoring items viewed from the path of exposure. There are also some general procedures that one should follow. For example, double identities should be placed on samples at collection time. It is advisable to fill in a standard form with all relevant information (date, location, fresh weight, weather, collector s name, etc.).

You must maintain such items as documentation of the urine collection and/or alcohol testing personnel s training, proficiency, and refresher training the collector s copy of the chains of custody and records of calibration tests of breath alcohol testing equipment. 

The history of the Kresge-Hooker Science Library at Wayne State University is briefly reviewed. Some outstanding items of the periodical collection are enumerated, as well as some collectors items of interest to historians of chemistry. Current subscriptions to scientific periodicals include numerous titles which are not found widely in other libraries in this country. An abbreviated list of such periodicals has been compiled. Close proximity of the Detroit Public Library to the Kresge-Hooker Science Library on Wayne s campus, located in the heart of the city, provides excellent science library facilities for the students of that large urban university, the chemical and engineering industries, and the citizenry of Detroit alike. 

We let / = 1, , 7, , Wm denote the set of sites in tier m. The entities in the upstream boundary tier collect recycled items from the source, and the source supplies the upstream boundary tier site on the basis of a fee paid by the upstream boundary tier site. We let S denote the collection amount in upstream boundary tier site i e /i and be the collection fee per unit of the recycled item paid by site i e Ii. We characterize the collection amount for the upstream boundary tier site i e /i by a linear function 5, = a, bi, where a,- and fe, are parameters and Ui, bi > 0, The collection fee, pf ° of site i e /i is without sign restriction. The use of a linear function allows the analysis of the problem to be simplified. It captures a qualitative market behavior of increased flow with either an increased payment or a decreased collection fee (charged by the collector). In other words, the upstream boundary tier site may pay or charge for collecting recycled items if p is positive or negative, respectively. 

By a remarkable coincidence, Alfred Russel Wallace - a professional plant collector, working in the tropics of South East Asia - hit upon more-or-less the same theory of species origin as Darwin (Raby, 2002). He commimicated his ideas directly to Darwin in a letter from Ternate, Eastern Indonesia. Wallace s essay was published in 1858 as On the Tendency of Varieties to Depart Indefinitely from the Original Type (Darwin and Wallace, 1858 Darwin contributed a few items to the presentation but had no input into Wallace s title essay). Wallace s communication has great significance, as it helped inspire Darwin to complete what he called the abstract of his theory, the book that became On the Origin of Species.
