Source control

The operator sets TU on the area to be controlled and puts the button B Under the command of SC EDC impulse of proper value and duration is formed in source controllable current (SCC).

The enforcement function may be subdivided in several ways, one of which is control of new sources and existing sources. New-source control can involve all or some of the following functions ... 

All efforts to prevent or correct LAQ problems should include an effort to identify and control pollutant sources. Source control is generally the most cost effective approach to mitigating LAQ problems in which point sources of contaminants can be identified. In the case of a strong source, source control may be the only solution that will work. The following are categories and examples of source control ... 

When you have pursued source control options and have increased ventilation rates and efficiency to the limits of your expertise, you must decide how important it is to pursue the problem further. If you have made several unsuccessful efforts to control a problem, then it may be advisable to seek outside assistance. The problem is probably fairly complex, and it may occur only intermittendy or cross the borders that divide traditional fields of knowledge. It is even possible that poor indoor air quality is not the actual cause of the complaints. Bringing in a new perspective at this point can be very effective. 

An overview of several technologies is presented in this section. Each of these technologies are point source controls for handling gaseous pollutants. They are all well-established methods of gas cleaning, some based on many decades of industry practice. 

EPA, 1998. U.S. EPA, Office of Air Quality Planning and Standards, "Stationary Source Control Techniques Document for Fine Particulate Matter," EPA-452/R-97-001, Research Triangle Park, NC, October, 1998. 

To maintain acceptable indoor air quality, the concentration of pollutants known to degrade indoor air quality and affect human health must be controlled. If the origin of the contaminant is known, it is more effective to exercise source control over any mitigation strategy. If the origin of the contaminants is not known, building ventilation and air cleaning and filtration are the two most commonly used processes to dilute or remove all types of contaminants from the indoor air and maintain acceptable indoor environmental conditions. 

Clipperton and Orozco Transforms (10-12°N EPR) (Fig. 2D). These authors analyzed samples known to be derived from a heterogeneous source based on their Sr/ Sr signatures and found a strong relationship between ( Th)/( Th) and Th (and U) concentrations of their samples. This study was the first to suggest that small-scale mafic heterogeneities in the mantle source control much of the U-series systematics of MORE. 

Inadequate diagnosis resulting in poor initial antimicrobial selection, poor source control, or the development of a new infection with a resistant organism is a relatively common cause of antimicrobial failure. 

While selection of antimicrobial therapy may be a major consideration in treating infectious diseases, it may not be the only therapeutic intervention. Other important therapies may include adequate hydration, ventilatory support, and other supportive medications. In addition, antimicrobials are unlikely to be effective if the process or source that leads to the infection is not controlled. Source control refers to this process and may involve removal of prosthetic materials such as catheters and infected tissue or drainage of an abscess. Source-control considerations should be a fundamental component of any infectious diseases treatment. It is also important to recognize that there may be many different antimicrobial regimens that may cure the patient. While the following therapy sections...
