Selenium toxicity to honey bee (Apis mellifera L.) pollinators: effects on behaviors and survival.
No full textWe know very little about how soil-borne pollutants such as selenium (Se) can impact pollinators, even though Se has contaminated soils and plants in areas where insect pollination can be critical to the functioning of both agricultural and natural ecosystems. Se can be biotransferred throughout the food web, but few studies have examined its effects on the insects that feed on Se-accumulating plants, particularly pollinators. In laboratory bioassays, we used proboscis extension reflex (PER) and taste perception to determine if the presence of Se affected the gustatory response of honey bee (Apis mellifera L., Hymenoptera: Apidae) foragers. Antennae and proboscises were stimulated with both organic (selenomethionine) and inorganic (selenate) forms of Se that commonly occur in Se-accumulating plants. Methionine was also tested. Each compound was dissolved in 1 M sucrose at 5 concentrations, with sucrose alone as a control. Antennal stimulation with selenomethionine and methionine reduced PER at higher concentrations. Selenate did not reduce gustatory behaviors. Two hours after being fed the treatments, bees were tested for sucrose response threshold. Bees fed selenate responded less to sucrose stimulation. Mortality was higher in bees chronically dosed with selenate compared with a single dose. Selenomethionine did not increase mortality except at the highest concentration. Methionine did not significantly impact survival. Our study has shown that bees fed selenate were less responsive to sucrose, which may lead to a reduction in incoming floral resources needed to support coworkers and larvae in the field. If honey bees forage on nectar containing Se (particularly selenate), reductions in population numbers may occur due to direct toxicity. Given that honey bees are willing to consume food resources containing Se and may not avoid Se compounds in the plant tissues on which they are foraging, they may suffer similar adverse effects as seen in other insect guilds

In subsidium: the declining contribution of Germany and Eastern Europe to the Crusades to the Holy Land, 1221-91
No full text"Though for a short time the Lord had forsaken it [the Holy Land], with great mercy he gathered together his children and restored the whole land's people from men of different races and diverse languages and nations, so that therein the prophecy seemed to be fulfilled: 'Thy sons shall come from far, and thy daughters shall be nursed by thy side'. [As] he observed and drew [them] together, his heart wondered and he was glad when [many] had been directed to him across the great sea, especially those of Genoa, Venice and Pisa. The strength of the nations came to him, especially from France and Germany.
Bubble aspect ratio in dense bubbly flows: Experimental studies in low Morton-number systems
No full textAlmost every modelling approach of bubbly flows includes assumptions concerning the bubble shape. Such assumptions are usually made based on single bubble experiments in quiescent flows, which is far away from the flow field observed in large-scale multiphase facilities. Considering low Morton-numbers and the highly deformable interface at medium and large Eötvös-numbers, the evaluation of the bubble shape in such systems under real flow conditions is highly desirable. In this study, we experimentally evaluate the bubble shape (in terms of aspect ratio), at low Morton-numbers, in different bubble column setups and a pipe flow setup under different operating conditions. The bubble shape in the bubble column experiments were obtained with cameras at Politecnico di Milano and Helmholtz-Zentrum Dresden Rossendorf (HZDR) whereas the shapes in the pipe flows were measured by the ultrafast electron beam X-ray tomography system (ROFEX) at HZDR. In the bubble column experiments almost the same shape is observed; conversely, the shape in the pipe flows distinctly depends on the flow conditions. In conclusion, in bubble columns the assumption of a constant shape regardless of the flow conditions is valid whereas in pipe flows the turbulence and shear rates can be strong enough to deform distinctly the bubbles
Strange Attractors: A Commentary on Applications of Indeterminacy in my Recent Music
No full textThis commentary reflects on how indeterminacy has been used in the music I have written over the period of my doctoral studies, 2005-2008. Non-musical ideas play a major role in my compositional language and this is reflected in the use of 'strange attractors' as a metaphor for the philosophical and aesthetic stance behind composing with indeterminacy. After a brief introduction chapter, the links between strange attractors—and chaos theory in general—and indeterminate music are discussed. And applications of indeterminacy to pitch organisation techniques such as spectral modelling and frequency modulation are examined as part of a frequency-based harmonic continuum. Different methods of generating ambiguous pitch percepts that sit at the boundaries of the harmony/timbre duality are considered In pieces with text processes
Narrative art and act in the fourth gospel: aspects of the Johannine point of view
No full textThis thesis assumes that the narrative form of the Fourth Gospel is important for understanding the Gospel's meaning. Narrative is a communicative transaction whereby meaning is transmitted from author to reader via the way the story is told. Meaning is also established by overt speech-acts, and the 'act' performed in the overall structuring of the story. It arises within a context of rule-governed speech behaviour which determines parameters and implications that inform understanding. The Gospel's narrative form meets with readers' conventional expectations about how it relates to ostensive historical reality. Factors internal and external help determine genre. Part one examines aspects of the Gospel's narrative art. The way in which the narrative situation varies over the course of the narrative is outlined. The implied author manipulates the narration to create a close association in the reader’s mind between the narrator and the beloved disciple. In John 3 the voice of the narrator merges with those of Jesus and John. These strategies have implications for the Gospel's theological meaning and the relationship of the implied author to the story world. Speech-act theory elucidates the narrative act by which the implied author conveys the Gospel's message and seeks to induce belief in the reader. Part two considers the Gospel's relationship to historical reference. Factors which influence a decision as to whether or not the Gospel is to be taken as fictional are examined, for example, whether aspects of the narration suggest fictional discourse and whether the speech-acts operate within a 'pretended' world. Descriptive categories for the Gospel as natural narrative and 'display text' are proposed, as is a flexible model of genre, which modulates the poles of 'fiction' and 'history'. An analysis of the Temple Cleansing pericope provides illustration of the Gospel’s status as an historically-based, theological display text

Exploring consideration of future consequences and temporal focus as predictors of emotion regulation choice
No full textHow people regulate their emotions greatly impacts their mental health. Therefore, it is crucial to understand how individual traits influence which emotion regulation strategies people choose to use and how effective they are. One trait, the consideration of future consequences (CFC), refers to the degree to which people take future outcomes into account when making decisions. Focusing on the future may increase the use of strategies that are beneficial in the long-term, such as reappraisal (thinking differently about a negative event to reduce unpleasant feelings), rather than using maladaptive strategies like distraction (thinking about something unrelated to the situation). However, few studies examine the link between emotion regulation and CFC using experiments which induce real emotions in people. The current study used a newly developed task to induce real regret. Subsequently, participants were directed to focus on either the long- or short-term consequences of their regret, before choosing to implement either reappraisal or distraction. I expected that a future focus would increase the choice of reappraisal over distraction, especially in those who were high, compared to low, in trait CFC. However, results did not indicate a significant relationship between CFC, temporal focus, and participants’ ratings of strategy preference or their choice to implement one strategy over the other. These results are not in line with previous work in the area and may have been heavily influenced by an inadequate sample size
The use of computational fluid dynamics to assess the hull resistance of concept autonomous underwater vehicles
No full textAutonomous Underwater Vehicles (AUV’s) provide an important tool for collecting detailed scientific information from the oceans depths. The hull resistance of an AUV is an important factor in determining the powering requirements and range of the vehicle. This paper discusses the use of Computational Fluid Dynamics (CFD) to determine the hull resistance of three existing AUV’s, of differing shape and size. The predictions are compared with available experimental data and good agreement found. This work has demonstrated that with use of suitable shape parameterisation it is possible to carry out concept design evaluation using a RANS flow solver
