Late Winter Foraging by Honeybees (Hymenoptera: Apidae) at Sapsucker Drill Holes

Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did not feed directly at drill holes but collected congealed sap from bark surfaces

Leaders Pray with the Assembly

(Excerpt) I wonder what it was that prompted the disciples\u27 request. Had they watched Jesus praying, as was his custom, in a place apart and then seen him come back somehow changed-more refreshed, more serene, more focused, more disturbed? Had they overheard Jesus praying-the intimate conversation, the wrestling and struggle, the thanksgiving and praise, the intercessions? Had they remembered some admonition or invitation to pray? Did their own spirits feel dry and empty? Did they know some longing deep inside for a closer communion with the one Jesus called Abba? Was there in them some joy or anguish that needed to be offered to God? Lord, teach us to pray (Luke 11 : 1 )

\u3ci\u3eNeurocordulia (Platycordulia) Xanthosoma\u3c/i\u3e (Williamson) in Texas (Odonata: Libellulidae: Corduliinae)

(excerpt) The rarity of a species is usually judged by the number of specimens in collections, both private and institutional, and the number of places where it has been found or seen. On this basis, Neurocordulia xanthosoma (Williamson) is rare. Its crepuscular habits, its brown coloration, and its habitat requirements, coupled with the habits of most collectors, have been its protection. Nevertheless, because of its apparent special requirements and man\u27s modification of, and encroachment on, its environment, it may soon be a species of the past

\u3ci\u3eCoreopsis Tinctoria\u3c/i\u3e: An Unrecorded Host Plant of Adult \u3ci\u3eCalligrapha Callfornica Coreopsivora\u3c/i\u3e (Coleoptera: Chrysomelidae)

Adults of Calligrapha californica coreopsivora are recorded feeding upon cultivated Coreopsis tinctoria in southwestern Virginia. Coreopsis tinctoria is an unrecorded host plant of this beetle

\u3ci\u3eChrysochus Auratus\u3c/i\u3e (Coleoptera: Chrysomelidae) Absolved as Pecan Pest

Chrysochus auratus, the dogbane beetle, has been erroneously implicated as a pecan defoliator in the early literature. Alternative scenarios suggest other chrysomelid species that may have been responsible for the defoliation

Theory of Feshbach molecule formation in a dilute gas during a magnetic field ramp

Starting with coupled atom-molecule Boltzmann equations, we develop a simplified model to understand molecule formation observed in recent experiments. Our theory predicts several key features: (1) the effective adiabatic rate constant is proportional to density; (2) in an adiabatic ramp, the dependence of molecular fraction on magnetic field resembles an error function whose width and centroid are related to the temperature; (3) the molecular production efficiency is a universal function of the initial phase space density, the specific form of which we derive for a classical gas. Our predictions show qualitative agreement with the data from [Hodby et al, Phys. Rev. Lett. {\bf{94}}, 120402 (2005)] without the use of adjustable parameters

Lincoln Advanced Science and Engineering Reinforcement (LASER) program

Lincoln University, under the Lincoln Advanced Science and Engineering Reinforcement (LASER) Program, has identified and successfully recruited over 100 students for majors in technical fields. To date, over 70 percent of these students have completed or will complete technical degrees in engineering, physics, chemistry, and computer science. Of those completing the undergraduate degree, over 40 percent have gone on to graduate and professional schools. This success is attributable to well planned approaches to student recruitment, training, personal motivation, retention, and program staff. Very closely coupled to the above factors is a focus designed to achieve excellence in program services and student performance. Future contributions by the LASER Program to the pool of technical minority graduates will have a significant impact. This is already evident from the success of the students that began the first year of the program. With program plans to refine many of the already successful techniques, follow-on activities are expected to make even greater contributions to the availability of technically trained minorities. For example, undergraduate research exposure, broadened summer, and co-op work experiences will be enhanced
