Protected areas

Step 3. Boron is ion implanted around the perimeter of the resist-protected area to form a "typ isolation border (the channel stopper or chanstop). The boron cannot penetrate through the resist. 

Factors that are important for the limitation of protected areas are the pipe network structure, degree of mesh, number of service pipes, type of pipe connections, quality of the pipe coating and availability of protection current as well as stray current effects. A protected area in a distribution network is shown in Fig. 10-11 with separate parts of the network (NT I to NT IV). Previous experience has shown that protected areas of 1 to 2 km with lengths of pipeline from 10 to 20 km are advantageous [30],... 

The danger of corrosion is in general greater for pipelines in industrial installations than in long-distance pipelines because in most cases cell formation occurs with steel-reinforced concrete foundations (see Section 4.3). This danger of corrosion can be overcome by local cathodic protection in areas of distinct industrial installations. The method resembles that of local cathodic protection [1]. The protected area is not limited, i.e., the pipelines are not electrically isolated from continuing and branching pipelines. 

Provide warning notices to identify containers and areas where corrosive chemicals are in use, and instructions regarding necessary protection, particularly eye protection areas Identify vessels, pumps and pipelines (e.g. colour coding, numbering)...

The Northwest Power Plamimg Council designates 44,000 miles of Northwest streams as protected areas because of their importance as critical fish and wildlife habitat. 

Intruder alarms are designed to give a warning of the presence of an intruder within or attempting to enter the protected area. Alarm systems may act as a deterrent to the casual or opportunist thief but they will do little or nothing to prevent a determined intrusion, and to be effective they must provoke an early response from the appropriate authority (in most cases the police). The warning may be a local audible device, but normally the alarm signal is transmitted by the telephone network to a central station operated by a security company on a 24-hour basis. 

High-alloy pipeline steels (e.g. austenitic-ferritic or duplex) have been used where the product stream demands materials with better corrosion resistance than carbon steel. In practice the external corrosion resistance of these materials cannot be guaranteed, so cathodic protection is employed to protect areas which may be subject to corrosion. 

Footprinting DNA with protein bound is resistant to digestion by DNase enzymes. When a sequencing reaction is performed using such DNA, a protected area, representing the footprint of the bound protein, will be detected. 

Four Ramsar sites, namely Cerknisko Jezero (SLO), Lonjsko Polje (CRO), Bardaca (B H) and Obedska Bara (SER), and numerous important bird and plant areas, protected areas at the national level, and Natura 2000 sites have been designated in the Sava river basin. 

What are the benefits of protected habitats in terms of water resources relative to a non-protected area ... 

Rooted aquatic plants, such as wild rice (Zizania aquatica), can accumulate up to 67 mg Pb/kg dry weight when cultured in tanks contaminated with high concentrations of powdered lead (equivalent to 7400 kg Pb/ha) however, this level is not considered hazardous to waterfowl feeding on wild rice (Behan et al. 1979). Lead content in plants collected from heavily hunted areas near refuges did not differ from those collected in the protected areas (Behan et al. 1979), which suggests that lead bioavailability to rooted aquatics is substantially lower from shot than from powdered lead. 

The Non-renewable Resource Assessments (NRAs) are part of step 5 in an 8-step process that may ultimately result in (partial or limited) protection of certain areas from development. Phase 1 of an NRA is a desktop exercise that evaluates all existing mineral deposit and survey data for an area from all sources, determines knowledge gaps of the mineral potential, and suggests an approach for Phase 2 follow-up work. Phase 2 of the NRA typically involves field and analytical work designed to lead to a better understanding of the resource potential for a candidate protected area. 

Each proposed protected area (PPA) is represented by a Working Group...

Cooperation is imperative in this process, and education and outreach go hand-in-hand with consensus building. Community meetings are part of the process and an understanding of the First Nations cultural landscape is an importantasset. Some of the proposed protected areas also play in land claim settlements between the federal government and First Nations people. 

Results of the Edehzhie survey (a hybrid survey) have been used to adjust suggested protected area boundaries and make compromises in light of mineral potential. There is a high kimberlite potential on the Horne Plateau, as suggested by the presence of indicator minerals and a small diamond recovered from a bulk stream sediment sample (Day et al., 2007). 

Potential for diamond-bearing kimberlites is also present Sambaa K e area. There are basement and structural similarities with the Buffalo Head Hills kimberlite field, Alberta (Prior et al. 2007) and there is ongoing diamond exploration within the WCSB to the north as well. Further discussion has altered the potential boundaries for the proposed protected area on the Horn Plateau and discussions are ongoing before any permanent decisions are made by all parties involved. Analytical results for the remaining two areas are pending.
