FDA/CFSAN OPA: Recommendations for Submission of Chemical and Technological data for Direct Food Additives and GRAS food ingredient petitions Food additives generally fall into two broad categories: (1) those that are added directly to food, as codified in 21 CFR Part 172, and (2) those that are added indirectly to food through contact of the food with packaging materials, processing equipment, or other food-contact materials, as codified in 21 CFR Parts 174-178. Briefly, these encompass five general areas of information: (1) the identity of the additive; (2) the proposed use of the additive; (3) the intended technical effect of the additive; (4) a method of analysis for the additive in food; and (5) full reports of all safety investigations with respect to the additive. Standard solutions, consisting of the additive, ingredient, or any other analyte of interest, in an appropriate solvent, should be prepared at five different concentrations that bracket the use level or expected concentration of the substance in food and analyzed in triplicate. www.cfsan.fda.gov /~dms/opa-cg4.html   (4090 words)

AMA (CME) AMA PRA Category 1 Activities and Credit Hours If a group of physicians chooses to use AMA PRA category 1 enduring materials, then a facilitator needs to be assigned in order to lead discussion. If sections of a designated activity do not satisfy all the requirements for AMA PRA category 1 credit, then these sections must be clearly identified and excluded from the designation statement. Physicians may claim Category 2 credit toward the PRA for such physician directed learning activities as: the teaching of residents, medical students, or other health professionals; online study; reading authoritative medical literature; or attending live activities not designated for AMA PRA category 1 credit. www.ama-assn.org /ama/pub/category/2938.html   (4090 words)

Flooring - Concrete Flooring Concrete materials for Construction and Civil Engineering that are quick, simple and safe to use. Rockbond SCP materials meet Department of Transport Specifications. Concrete treated with stains or colorants to create rich variety of hues, textures, or stamped with patterns to mimic natural surfaces from marble to wood planks. Resulting floor finishes combine beauty, creativity with economy, durability, and practicality of concrete. Painting concrete is starting to become an increasing fad in the flooring world. This is still a relatively new concept so there are very few flooring professionals out there who are fully equipped to handle such projects. The popularity of painting concrete floors will soon fix this though. www.dellflooring.com /concreteflooring   (2604 words)

Ch25 Archival material has not only to be evaluated and to be stored in the format common at the time when the programme is produced, all not-used materials rather have to be transferred onto the changing format standards - and this is an important cost factor. Programmes in this category are those designed to entertain and amuse. Where purchased material forms part of a new programme produced by the company, the new programme should be retained by the company, which should note in its documentation the rights held in that material. www.unesco.org /webworld/ramp/html/r9704e/r9704e0q.htm   (1377 words)

Realty Times - Real Estate News and Advice Installing Category 5 wiring in new construction costs pennies more than installing Category 3 wiring, but trying to retrofit the faster wires can be costly, depending upon the materials and the structure and design of your home. Category 5 moves voice and data at a minimum of 100 megabytes per second and supports local area networks (LANs), providing the ability to use a home printer from the kitchen laptop, for instance. If you need to upgrade your home's wiring service, be aware that Category 5 wiring, available at hardware or electronics retailers, pumps digitized data at maximum speeds only when it's part of a structured wired system. realtytimes.com /rtnews/rtcpages/20000407_broadband.htm   (505 words)

Homepage Type Ia, layering by so-called ridge-lamellae, is defined as a category in which lamellae run parallel or near-parallel to the base of the scale. The cuticle material itself is a composite of rods of chitin set in a matrix of proteins. Type IIa comprise the simplest form of such body-lamellae systems in which the lamellae are parallel and flat across the entire area of the scale (allowing for any curvature of the scale itself). newton.ex.ac.uk /research/emag/butterflies/classification_page.htm   (2542 words)

The Food Additives Business Direct food additives, i.e., those intentionally added to food, as opposed to chemicals that for example, can migrate into food from packaging materials; the latter are called indirect food additives and are outside our scope. First of all, food additives are, after all, chemicals, either synthetic or natural, and therefore, this is a "chemical" study with all its concomitant public and political perceptions and problems. Government personnel, because food additives, since they are deliberately incorporated into foods, are watched and regulated by governments at all levels from the local to the federal. www.marketresearch.com /researchindex/802151.html   (2259 words)

N. Scott Robinson-World Music and Percussion, Frame Drums, Riq, Tambourines Mbira are made from an assortment of materials, such as wood, metal gas and insecticide cans, gourds and coconut shells, and in a great variety of sizes, shapes and types, and they exist as acoustic or electric instruments. Ethnomusicologists use another term that places all these instruments in a single generic category: "lamellaphone" (also lamellophone) designates any instrument with plucked keys (or lamellae) attached to a soundboard, with the possible addition of a resonator. The material used for the keys varies: some are made from a heavier, stiffer metal that requires the player to have a longer thumbnail to play comfortably, while others may be of a softer, more flexible metal that makes plucking with the fingertip comfortable. www.nscottrobinson.com /mbira.php   (3751 words)

Wisconsin Enterprise Standards - Network LAN/Voice Cable Category 6 cable should be considered where long building occupancy is expected (beyond December 31, 2007) and the total cost of installing Category 6 cable (materials and labor) is less than 15% more than the cost of installing Category 5e cable. Category 5e UTP cable is also recommended for voice in wiring projects with an expected lifetime past December 31, 2006 even though there is an incremental cost increase over Category 3 cable. Category 5e cable will allow the use of a common patch panel for both voice and data cabling, reducing the agency costs for moves/adds/changes. enterprise.state.wi.us /home/standards/std0516_new.htm   (3751 words)

Champions Technical Support Library's hardware concepts: C The electricity-handling properties of cables determine their function: (1), data and/or voice impedance; (2), attenuation, and grounding capacitance; (3), stranded or solid wire; (4), shielding materials may be either foil tape or braided; (5), shielding of individual wires, pairs of wires, groups of wires, overall, and not at all. Category 5 cable is the recommended choice for most installation because it offers the most resistance to the four CAIN raisers that afflict networks. When ordering cable, determine your maximum requirements for the cable&emdash;how much power it may carry, the length of the longest cable, how much shielding it may need, the physical environment where it will be laid, and cable function. home.earthlink.net /~champions/h_c.htm   (3751 words)
