Two experiments were conducted to characterize changes associated with ontogenetic aging in coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and to identify possible maturation "markers" for this species. In the first experiment (Experiment 1), scions of ages 1, 4 and 9 years were collected from four seed zones in field progeny tests and grafted onto 1-year-old rootstocks. In Experime...
Adventitious branches are produced following lnjury in at least 5 specles of brown algae in the family Fucaceae. Field experiments showed that these structures can be induced in the intertidal brown alga Fucus distichus by mechanical damage to the plant apices. The mean number of adventitous branches on F. distichus and the percent of plants with adventitious branches was positively correlated ...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...
To determine a suitable method and time of top-working for inferior walnut trees, a preliminary study was conducted to compare nine different grafting or budding methods. Two promising methods including modified bark grafting and cleft grafting at two times (early April and mid April) were further evaluated during 2001- 2006, in terms of grafting percentage and subsequent impact on growth and ...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
OBJECTIVES This study was designed to assess the functional significance of side branches after stent implantation in main vessels using fractional flow reserve (FFR). BACKGROUND Little is known about the functional significance of side branches after stent implantation in main vessels in coronary bifurcation lesions. METHODS Between May 2007 and January 2011, 230 side branches in 230 patie...
The hemagglutinin protein of influenza virus bears several sites of N-linked asparagine glycosylation. The number and location of these sites varies with strain and substrain. The human H3 hemagglutinin has gained several glycosylation sites on the antigenically important globular head since its introduction to humans, presumably due to selection. Although there is abundant evidence that glycos...
In his celebrated Tutte l’Opere d’Architettura published over the period 1537–1575 Sebastiano Serlio introduced four techniques for constructing ovals which have thereafter been applied by many architects across Europe. Using various geometric forms (i.e. the triangle, square, and circle) as a basis they produced ovals made up from four circular arcs. This paper analyses both Serlio’s construct...
