The Effects of Herbicidal Spraying Upon a North Central Utah Blue Grouse Population

The effects of herbicidal spraying upon a North Central Utah blue grouse population were studied. Baseline data were obtained in 1970 and 1971 prior to the spraying on June 2, 1972. The spraying was done to control wyethia (Wyethia amplexicaulis) and black sage (Artimesia nova) which covered 48 percent and 20 percent of the study area respectively. No differences in blue grouse numbers occurred following spraying with 17 to 20 broods using the area in 1972 compared to 18 to 20 broods in 1971. Total population of blue grouse each year was between 90 and 104 birds. Distribution of blue grouse changed, with the birds using areas with trees and shrubs following spraying rather than open areas that were sprayed. There was significantly more black sage on the control area than the spray area. These differences began before spraying, however, and cannot be attributed solely to the spray. No differences occurred in insect numbers or songbird use of the spray and control area

The removal of Jabba from Carnarvon in 2006 November

Ian Barnes, Brek Miller, and Barry Jackson visited Carnarvon late in 2006. Jabba was removed from the mount, the weather cabling was replaced, all the dome roolers were replaced, the cloud detector LDR was replaced, some mount limit switches were replaced, the computer was replaced, the temperature onitor was reconfigured to monitor different things, the PMTEB was replaced, and the autoguider was realigned

On-Campus Versus Off-Campus: A Comparative Analysis Of MBA Learning Outcomes For A Classroom-Based Program

Both direct and indirect measures of learning outcomes provide data that can be used to improve learning. The research reports a study of an indirect measure of learning outcomes in an MBA program. The measure was a Post-Then format using a five point Likert scale. Thirteen courses were analyzed generating 107,440 responses over a 5-year period. Two research questions were addressed: Are MBA students learning as demonstrated by an improvement in learning outcomes? and, Is there a difference in learning outcomes for on-campus versus off-campus students? Results are presented and future research directions are offered

An Examination Of Kolb's Learning Style Inventory

As educators our primary focus is that of ensuring that students experience positive learning outcomes. Research, however, has shown that there are differences in students learning styles and that these differences will impact on the overall learning process. One way of ensuring that these positive outcomes are achieved is by identifying the different learning styles of students and modifying our teaching methodology to meeting those needs. This paper examines Kolbs (1984) Learning Style Inventory and provides suggestions on how to address the different students learning styles in order to enhance the learning process

The effect of spacer morphology on the aerosolization performance of metered-dose inhalers

Purpose: Respiratory drug delivery has been attracted great interest for the past decades, because of the high incidence of pulmonary diseases. However, despite its invaluable benefits, there are some major drawbacks in respiratory drug delivery, mainly due to the relatively high drug deposition in undesirable regions. One way to improve the efficiency of respiratory drug delivery through metered-dose inhalers (MDI) is placing a respiratory spacer between the inhaler exit and the mouth. The aim of this study was to assess the effect of type and shape of spacer on the aerosolization performance of MDIs. Methods: A commercial Beclomethasone Dipropionate (BDP) MDI alone or equipped with two different spacer devices (roller and pear type) widely distributed in the world pharmaceutical market was used. The effect of spacers was evaluated by calculating aerosolization indexes such as fine particle fraction (FPF), mass median aerodynamic diameters (MMAD) and geometric standard deviation (GSD) using the next generation impactor. Results: Although one of the spacers resulted in superior outcomes than the other one, but it was not statistically significant. Conclusion: The results confirmed that the type and shape of spacer did not substantially influence the aerosolization performance of MDIs

Watching movies unfold - a frame-by-frame analysis of the associated neural dynamics

Our lives unfold as sequences of events. We experience these events as seamless, although they are composed of individual images captured in between the interruptions imposed by eye blinks and saccades. Events typically involve visual imagery from the real world (scenes), and the hippocampus is frequently engaged in this context. It is unclear, however, whether the hippocampus would be similarly responsive to unfolding events that involve abstract imagery. Addressing this issue could provide insights into the nature of its contribution to event processing, with relevance for theories of hippocampal function. Consequently, during magnetoencephalography (MEG), we had female and male humans watch highly matched unfolding movie events composed of either scene image frames that reflected the real world, or frames depicting abstract patterns. We examined the evoked neuronal responses to each image frame along the time course of the movie events. Only one difference between the two conditions was evident, and that was during the viewing of the first image frame of events, detectable across frontotemporal sensors. Further probing of this difference using source reconstruction revealed greater engagement of a set of brain regions across parietal, frontal, premotor, and cerebellar cortices, with the largest change in broadband (1–30 Hz) power in the hippocampus during scene-based movie events. Hippocampal engagement during the first image frame of scene-based events could reflect its role in registering a recognizable context perhaps based on templates or schemas. The hippocampus, therefore, may help to set the scene for events very early on
