Tetra­carbonyl­bis(η5-cyclo­penta­dienyl)bis[(dec-9-en-1-yl)diphenyl­phosphine]dimolybdenum(0)(Mo—Mo) tetra­hydro­furan disolvate

The asymmetric unit of the title compound, [Mo2(η5-C5H5)2(C22H29P)2(CO)4]·2C4H8O, contains two half-mol­ecules of the organometallic species and two solvent mol­ecules. Both organometallic mol­ecules are completed by crystallographic inversion symmetry, yielding dimeric units with Mo—Mo single-bond lengths of 3.2703 (6) and 3.2548 (6) Å. Each Mo atom is also coordinated by an η5-cyclo­pentdienyl ligand, two carbonyl ligands, and a (dec-9-en-1-yl)diphenyl­phosphine ligand

The title compound, [Mo2(C5H5)2(C12H11P)2(CO)4]·C6H14, is a centrosymmetric Mo complex in which two Mo atoms are connected by an Mo—Mo bond [3.2072 (12) Å]. Each Mo atom is coordinated by an η5-cyclo­penta­dienyl ligand, two carbonyl ligands and a diphenyl­phosphine ligand in a piano-stool fashion

Progress on Gust Load Alleviation Wind Tunnel Experiment and Aeroservoelastic Model Validation for a Flexible Wing with Variable Camber Continuous Trailing Edge Flap System

This paper discusses a wind tunnel experiment of active gust load alleviation of a flexible wing which took place at University of Washington (UW) in 2019. The experiment performed under a NASA SBIR contract with Scientific Systems Company, Inc (SSCI). The objective of the experiment is to demonstrate active controls of the Variable Camber Continuous Trailing Edge Flap (VCCTEF) system for gust load alleviation and real-time drag optimization. The wind tunnel model is a 8.2% sub-scale Common Research Model (CRM) wing. The wing structure is designed to provide a substantial degree of flexibility to represent that of a modern high-aspect ratio wing. Eight active control surfaces are employed in the VCCTEF. A new gust generator system was designed and installed by UW under a sub-contract with SSCI. The first test entry started in July 2019 and ended in September 2019. During this test entry, many significant issues were found with the hardware and software. The significant issues with the servos prevented the test objective from being completed. A follow-up second test entry in 2020 is being planned. The wing system is being repaired by SSCI. This paper reports on the progress of this experimental effort and the aeroservoelastic (ASE) model validation which was conducted during the test entry

Linking diet switching to reproductive performance across populations of two critically endangered mammalian herbivores

Optimal foraging theory predicts that animals maximise energy intake by consuming the most valuable foods available. When resources are limited, they may include lower-quality fallback foods in their diets. As seasonal herbivore diet switching is understudied, we evaluate its extent and effects across three Kenyan reserves each for Critically Endangered eastern black rhino (Diceros bicornis michaeli) and Grevy’s zebra (Equus grevyi), and its associations with habitat quality, microbiome variation, and reproductive performance. Black rhino diet breadth increases with vegetation productivity (NDVI), whereas zebra diet breadth peaks at intermediate NDVI. Black rhino diets associated with higher vegetation productivity have less acacia (Fabaceae: Vachellia and Senegalia spp.) and more grass suggesting that acacia are fallback foods, upending conventional assumptions. Larger dietary shifts are associated with longer calving intervals. Grevy’s zebra diets in high rainfall areas are consistently grass-dominated, whereas in arid areas they primarily consume legumes during low vegetation productivity periods. Whilst microbiome composition between individuals is affected by the environment, and diet composition in black rhino, seasonal dietary shifts do not drive commensurate microbiome shifts. Documenting diet shifts across ecological gradients can increase the effectiveness of conservation by informing habitat suitability models and improving understanding of responses to resource limitation

The 'others' amongst 'them' – selection categories in European resettlement and humanitarian admission programmes

The chapter looks at categorisations as a form of ‘othering’ in the context of European refugee resettlement. Selection categories in resettlement provide insights into states’ preferences, when given the possibility to effectively select refugees before they present themselves at the border. As such, categorisations in such programmes are ways of othering within the group of ‘others’, excluding but also including according to three logics: humanitarian, security and assimilability. The chapter provides a panoramic view of official selection categories of the United Nations High Commissioner for Refugees (UNHCR), European Member States, and the European Union (EU). The analysis shows that, while resettlement is framed as a humanitarian policy for the ‘most vulnerable’, some European states’ programmes and recent EU propositions indicate that besides a humanitarian logic, security and assimilability logics of ‘othering’ also draw the boundaries of access to this privileged form of refugee protection

Patients Have Poor Postoperative Recall of Information Provided the Day of Surgery but Report Satisfaction With and High Use of an E-mailed Postoperative Digital Media Package

Purpose: To understand what portions of the surgical day patients remember, what parts of an e-mailed media package regarding their surgery patients are used, and how that information affects their surgical experience. Methods: Patients undergoing an outpatient arthroscopic procedure were approached in the preoperative area and asked to remember 3 words. Postoperatively, they were seen by the surgeon to discuss surgical findings and instructions. They were then e-mailed a multimedia package containing a thank you letter, postoperative instructions, annotated arthroscopy images, and a personalized video from the surgeon. Patients were called 2 to 5 days after surgery to answer survey questions and recall the 3 words they were told on the day of surgery. Results: Of the 160 patients, 100% received and accessed the e-mail. When asked if they remembered the postoperative conversation, 125 (78.1%) patients responded yes and 35 (21.9%) responded no. When asked to rate how well they remembered the postoperative conversation, 75.2% patients rated their memory very poor (48, 38.4%) or poor (46, 36.8%). Similarly, 129 (80.6%) patients were unable to remember the 3 surgeon-related words. One hundred percent of patients strongly agreed (145, 90.6%) or agreed (15, 9.4%) the e-mail package enhanced their experience. In addition, 100% of patients strongly agreed (150, 93.8%) or agreed (10, 6.2%) the surgeon video enhanced their experience. The average e-mail shares per patient was 2.5, with 158 (98.7%) of patients sharing the e-mail at least once. Conclusions: This study shows that patients had poor memory of in-person conversations on the day of surgery. However, patients were satisfied with a postoperative multimedia package provided via e-mail after surgery. Patients interacted with the e-mail primarily on their cell phones, liked the surgeon video, and shared the e-mail with others. Level of evidence: Level IV, therapeutic case series
