Abstract:
... Production models of a USDA-developed aerial electrostatic spray application system are currently being marketed in the US and abroad. Spray deposit and insect mortality studies conducted on cotton with the USDA prototype are summarized. Spray deposits with the electrostatic system were higher than with conventional aerial application systems. The increased deposits with the electrostatic system d ...

Abstract:
... Microsatellites have many desirable marker properties and have been increasingly used in crop plants in genetic diversity studies. Here we report on the characterisation of microsatellite markers and on their use for the determination of genetic identities and the assessment of genetic variability among accessions from a germplasm collection of hop. Thirty-two polymorphic alleles were found in the ...

Abstract:
... Recent research on the phenomena and manifestations of bereavement, as represented in this ABS special issue, has contributed to the understanding of two central, long-standing questions: How do bereaved persons cope with their loss? What is the nature and meaning of normal versus complicated grief? In this review, these themes are linked to historical trends, evaluation is made of current knowled ...

Culture of glands from 120-h-old larvae (puff stage 1) in the presence of ecdysone resulted in the initiation of the late-larval puffing cycle that is normally observed in 145-h-old larvae (puff stage 4). During a 7-h period in the pres ...

Abstract:
... Traditional bereavement theories emphasize that it is crucial to work through the emotional meanings of a loss and that the failure to do so typically results in delayed grief symptoms. This article reports data examining these assumptions prospectively across the first 5 years of bereavement. Based on previous validity data, elevated symptoms were defined in terms of 6-month median scores for eac ...
