Tailoring the microstructure and suppressing the β-AlFeSi intermetallic formation in 319 aluminum alloy through spray forming
Contributors: Lucas Otani
... Iron has very low solubility in aluminum, leading to the formation of Fe-rich intermetallic phases, such as β-AlFeSi. This phase forms with a platelet-like morphology that is detrimental to the mechanical properties of the alloy. It is well known that by applying high cooling rates or by adding manganese to the alloy it is possible to stabilize the α-AlFeSi or α-Al(Fe,Mn)Si intermetallic phase instead of the more detrimental β-AlFeSi. Spray forming is an advanced casting process that has been described as a potential technique to suppress β-AlFeSi formation. This work investigated the effect of different processing parameters on the microstructure evolution of spray-formed aluminum 319 alloy, mainly regarding the formation of α and β intermetallic phases. Results showed that the suppression of the β-AlFeSi strongly depends on the processing conditions and can be explained by the solidification mechanism prevailing in spray forming.

... Abstract of associated article: We examine the largest cost component in offshore development projects, rig rates. High rig rates in recent years have restricted development of new oil and gas fields, as well as IOR projects and thus increased the cost for importing countries. Thus, it is important to understand developments in rig rates. Using econometric analysis, we examine the effects on jackup rig rates from gas and oil prices, rig capacity utilisation, contract length and lead time, and rig-specific characteristics like drilling depth capacities and rig classification. Having access to a unique data set from the Gulf of Mexico (GoM), containing contract information, we are able to estimate how contract parameters crucial to the relative bargaining power between rig owners and oil and gas companies affect rig rates. We find that increasing lead times and contract lengths enhance the bargaining power of the rig companies and are likely to be associated with higher rates for new contracts. Further, we find that gas prices are more important for jackup rig rates in the GoM area than oil prices — ten percent increase in gas prices leads to nine percent increase in rig rates in the long run, according to our results.
Data from: A novel method for using ecoacoustics to monitor post‐translocation behaviour in an endangered passerine

... 1. Conservation translocations are an important tool in wildlife management, but have traditionally suffered from a low success rate. Increasing understanding of animal behaviour is vital in improving the success of translocations, but few methods exist to efficiently monitor highly mobile and cryptic species post-release. 2. We present a novel approach to using dynamic occupancy modelling in combination with data derived from autonomous acoustic recording units to monitor the post-release behaviour of hihi (Notiomystis cincta), a threatened endemic bird, at a translocation site in New Zealand. The process of analysing large quantities of acoustic data was facilitated by using automated classifiers and manual validation, an approach that was both accurate and efficient. 3. We find that this approach detects behavioural change consistent with the transition from exploration of a new site to territory formation. We identify that hihi territories at the study site were closely linked to watercourses, but were not related to distance from release site. 4. We find that this method is able to effectively monitor post-release dispersal, and could provide a cost-efficient and less invasive alternative to radio-tracking for monitoring of vocal species.
Walking back to the future: The impact of walking backward and forward on spatial and temporal concepts

... This is the data and the script for the analysis of a manuscript submitted to be published. Abstract: Embodied cognition frameworks suggest a direct link between sensorimotor experience and cognitive representations of concepts (Shapiro, 2011). We examined whether this holds also true for abstract concepts that cannot be directly perceived with the sensorimotor system (i.e., temporal concepts). To test this, participants learned object – space (Exp. 1) or object – time (Exp. 2) associations. Afterwards, participants were asked to assign the objects to their location in space/time meanwhile they walked backward, forward, or stood on a treadmill. We hypothesized that walking backward should facilitate the on-line processing of ”behind”- and “past”-related stimuli, but hinder the processing of “ahead”- and “future”-related stimuli, and a reversed effect for forward walking. Indeed, “ahead”- and “future”-related stimuli were processed slower during backward walking. During forward walking and in the control condition, all stimuli were processed equally fast. The results provide partial evidence for the activation of specific spatial and temporal concepts by means of whole-body movements and are discussed in the context of movement familiarity.

... As a partner in Global Fund Round 7, PSI Angola is responsible for launching a nation-wide behavior change communication campaign to increase the use of insecticide treated mosquito nets among preg-nant women and children under five. PSI Angola will develop and launch a radio campaign directed at caregivers of children under the age of five. The present qualitative study is proposed to gain a greater understanding of the determinants of LLIN use from the user perspective in order to aid in the creation of focused, relevant and effective messages for the radio campaign.

... Analysis of one of the most comprehensive datasets to date of the largest passerine bird clade, Passerida, identified 10 primary well-supported lineages corresponding to Sylvioidea, Muscicapoidea, Certhioidea, Passeroidea, the ‘bombycillids’ (here proposed to be recognized as Bombycilloidea), Paridae/Remizidae (proposed to be recognized as Paroidea), Stenostiridae, Hyliotidae, Regulidae (proposed to be recognized as Reguloidea) and spotted wren-babbler Spelaeornis formosus. The latter was found on a single branch in a strongly supported clade with Muscicapoidea, Certhioidea and Bombycilloidea, although the relationships among these were unresolved. We conclude that the spotted wren-babbler represents a relict basal lineage within Passerida with no close extant relatives, and we support the already used name Elachura formosa and propose the new family name Elachuridae for this single species.
