Two different parameters for the quantitative description of beam halo are introduced, both based on moments of the particle distribution. One parameter is a measure of spatial halo formation and has been defined previously by Wangler and Crandall [3], termed the profile parameter. The second parameter relies on kinematic invariants to quantify halo formation in phase space; we call it the halo...

1 Faculty member,Agricultural and Natural Resources Research Center of Yazd, Yazd, Iran ABSTRACT. Seed germination and seedling growth are critical stages in the life cycle of a plant, especially under adverse abiotic stresses. Seed germination negatively affected by stress conditions. Seed priming techniques have been used to increase germination characteristics and improve germination uniform...

We have compiled a sample of 699 stars from the recent literature with detailed chemical abundance information (spanning −4.2 . [Fe/H] . +0.3), and we compute their space velocities and Galactic orbital parameters. We identify members of the inner and outer stellar halo populations in our sample based only on their kinematic properties and then compare the abundance ratios of these populations ...

Clusia is the only genus with bona fide dicotyledonous trees performing Crassulacean acid metabolism (CAM). Clusia minor L. is extraordinarily flexible, being C(3)/CAM intermediate and expressing the photosynthetic modes C(3), CAM, CAM-cycling, and CAM-idling. C(3) photosynthesis and CAM can be observed simultaneously in two opposite leaves on a node and possibly even within the same leaf in th...

in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....

As two of the top three Saint Mary’s administrators prepare to step down from their positions this spring — marking a new era at the College — students and faculty have the opportunity to meet two candidates vying for the position of vice president and dean of faculty at open forums this week. Saint Mary’s religious studies p ro fesso r Joe In c a n d e la and Dean of the Faculty a t Colgate Un...

"Holy Grail" is a well-known metaphor for the eternal spiritual pursuit for truth and wisdom. It suggests that in order for us to find what no one has found, we must search where few have looked. In 2013, a group led by Helen Mayberg published a groundbreaking paper that sought an answer to one of the most discussed conundrums in psychiatry and neuroscience: Can specific patterns of brain activ...
