Key to Utilization of Hardwoods Growing on Southern Pine Sites
For every cubic foot of pine on southern pine sites, there is about 0.8 cubic foot of hardwood. The shaping-lathe headrig, now in the final stages of commercialization, is a key to utilizing these small mixed hardwoods for paYets and industrial lumber. Lathe residues in the form of flakes can be the raw material for a new major industry manufacturing exterior structural flakeboard competitive i...

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Silvicultural Considerations in Managing Southern Pine Stands in the Context of Southern Pine Beetle
Roughly 30 percent of the 200 million acres of forest land in the South supports stands dominated by southern pines. These are among the most productive forests in the nation. Adapted to disturbance, southern pines are relatively easy to manage with even-aged methods such as clearcutting and planting, or the seed tree and shelterwood methods with natural regeneration. In addition, most species ...
متن کاملThe Southern Pine Beetle and Pine Forest Ecosystems
Dendroctonus frontalis, the southern pine beetle (SPB), is a highly destructive species of bark beetle that inhabits pine forests in the southern United States and parts of Central America. @6D In natural pine forests, the ecological role of the SPB presumably is to hasten the demise of weak or damaged trees, perhaps creating kindling for fires that contribute positively to the long-term health...
متن کاملMoisture Content of Southern Pine as Related
Holes 3-1/2 inches deep were bored with a I-inch spur machine bit in southern pine having specific gravity of 0.53 (ovendry weight and volume at 10.4 percent moisture). The bit was rotated at 2,400 rpm and removed chips 0.020 inch thick. For wood moisture contents ranging from ovendry to saturation, thrust was lower when boring along the grain (average 98 pounds) than across the grain (average ...
