International Emerging Infections Program

październik 1, 2008 · Dodaj komentarz

The collaboration between Guatemala’s Ministry of Public Health and Social Assistance (MPHSA) and the U.S. Centers for Disease Control and Prevention (CDC) was initiated in 2006 to establish the International Emerging Infections Program (IEIP) in Guatemala.

Based in Guatemala City and headquartered on the campus of the Universidad del Valle de Guatemala (UVG), the IEIP-Guatemala is part of a long-standing public health collaboration beginning with the Medical Entomology Research and Training Unit/Guatemala (MERTU/G). MERTU/G was established in 1978 under a tripartite agreement with the UVG, the Guatemalan Ministry of Health, and the Division of Parasitic Diseases at CDC. IEIP-Guatemala has a defined mission to strengthen capacity to identify and control emerging infections of regional and global significance. To fulfill this mission, IEIP-Guatemala focuses on the five core IEIP pillars of activity – surveillance, outbreak support, research, training, and networking.

Please explain the de minimis concentration limitation

Please explain the de minimis concentration limitation
The de minimis exemption allows covered facilities to disregard certain minimal concentrations of listed non-PBT chemicals in mixtures or trade name products when making threshold determinations and release and other waste management determinations. The de minimis exemption does not apply to the manufacture of a listed toxic chemical except if that listed toxic chemical is manufactured as an impurity and remains in the product distributed in commerce below the appropriate de minimis level or is imported below de minimis concentrations. The de minimis exemption does not apply to a byproduct manufactured coincidentally as a result of manufacturing, processing, otherwise use, or any waste management activity. The de minimis exemption does not apply to the PBT chemicals listed at 40 CFR section 372.28. When determining whether the de minimis exemption applies to a listed non-PBT chemical, the owner/operator should consider only the concentration of the listed toxic chemical in mixtures and trade name products. If the listed non-PBT chemical in a mixture or trade name product is manufactured as an impurity or imported, processed, or otherwise used and is below the appropriate de minimis concentration level, then the quantity of the listed toxic chemical in that mixture or trade name product does not have to be applied to threshold determinations nor included in release or other waste management calculations. If a listed non-PBT chemical in a mixture or trade name product meets the de minimis exemption, all releases and other waste management activities associated with the listed toxic chemical in that mixture or trade name product are exempt from EPCRA Section 313 reporting. It is possible to meet an activity (e.g., processing) threshold for a toxic chemical on a facility-wide basis, but not be required to calculate releases or other waste management quantities associated with a particular mixture or trade name product because that mixture or trade name product contains the non-PBT chemical below the de minimis level. Once a listed toxic chemical concentration is above the appropriate de minimis concentration, threshold determinations and release and other waste management calculations must be made, even if the chemical later falls below the de minimis level in the same process stream. Thus, all releases and other quantities managed as waste that occur after the de minimis level has been exceeded are subject to reporting. If a listed toxic chemical in a mixture or trade name product above the de minimis level is brought on-site, the de minimis exemption never applies. The de minimis concentration level is consistent with the OSHA Hazard Communication Standard requirements for development of Material Safety Data Sheets (MSDSs). The de minimis level is 1.0 percent except if the listed toxic chemical is an OSHA-defined carcinogen. The de minimis level for OSHA-defined carcinogens is 0.1 percent. For mixtures or other trade name products that contain one or more members of a listed Section 313 toxic chemical category, the de minimis level applies to the aggregate concentration of all such members and not to each individually. The list of toxic chemicals in the publication Toxic Chemical Release Inventory Reporting Forms and Instructions for the current reporting year contains the de minimis values for each of the non-PBT chemicals and chemical categories. This de minimis exemption applies solely to mixtures and other trade name products. EPA’s long-standing interpretation has been that mixture does not include waste. Therefore, the de minimis exemption cannot be applied to toxic chemicals in a waste. Additional guidance on the de minimis exemption can be found in Directive

Dymaxion

luty 20, 2008 · Dodaj komentarz

Fuller had designed and built prototypes of what he hoped would be a safer, aerodynamic Dymaxion car (“Dymaxion” is contracted from DYnamic MAXimum tensION, however it has also been reported that the name is a combination of the words dynamic, maximum, and ion, per the National Automobile Museum.) He worked with professional colleagues over a period of three years beginning in 1932. Based on a design idea Fuller had derived from aircraft, the three prototype cars were different from anything on the market. They had three wheels, with two (the drive wheels) in front, and the third, rear wheel being the one that was steered. The engine was in the rear, with the chassis and the body being original designs. The aerodynamic, somewhat tear-shaped body (which in one of the prototypes was about 5.5 metres or 18 feet long), was large enough to seat 11 people. It resembled a melding of a light aircraft (without wings) and a Volkswagen van of 1950s vintage. The car was essentially a mini-bus in each of its three trial incarnations, and its concept long predated the Volkswagen Type 2 mini-bus conceived in 1947 by Ben Pon.
