در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEpicormic Branches and Lumber Grade of Bottomland Oak
Epicormic branches can be a serious problem in management of hardwood forests for high-quality sawtimber production. In one study in central Alabama, defects caused by epicormic branches that developed following a partial cutting resulted in a 13 percent reduction in the value of willow oak lumber. Production of epicormic branches along the boles of hardwood trees is affected by species, stress...
متن کاملEpicormic Branches Affect Lumber Grade and Value in Willow Oak
A case study was conducted in a 50-yr-old bottomland oak stand in central Alabama to investigate the relationship between epicormic branches and lumber grade and value in willow oak (Quercus phellos L.). The stand had been thinnedfrom below 7-10 yr earlier, resulting in a wide variety of epicormic branch conditions on the residual trees. A sample of 41 willow oak trees was selected before the s...
متن کاملExcessive Exposure Stimulates Epicormic Branching in Young Northern Hardwoods
1 Sudden and excessive exposure of northern hardwood trees often causes growth responses that degrade tree quality, injuries that lead to tree deterioration, or both. The most sensitive and visible tree reaction to increased exposure is the formation of epicormic branches. Such branches may arise along the tree bole from either dormant or adventitious buds in response to some physiological stim...
متن کاملCurrent-year and subsequent-year effects of crop-load manipulation and epicormic-shoot removal on distribution of long, short and epicormic shoot growth in Prunus persica.
BACKGROUND AND AIMS The distribution of canopy growth among different shoot types such as epicormic, long and short shoots is not well understood in the peach tree. In this experiment, the effects of crop load and early epicormic sprout removal on current and subsequent-year distribution of vegetative growth among epicormic, long and short shoots was investigated in Prunus persica. METHODS Fi...
