Scanning Mechanism of the FY-3 Microwave Humidity Sounder

Astrium GmbH Germany, developed the scanning equipment for the instrument package of the MicroWave Humidity Sounder (MWHS) flying on the FY-3 meteorological satellite (FY means Feng Yun, Wind and Cloud) in a sun-synchronized orbit of 850-km altitude and at an inclination of 98.8 . The scanning mechanism rotates at variable velocity comprising several acceleration / deceleration phases during each revolution. The Scanning Mechanism contains two output shafts, each rotating a parabolic offset Antenna Reflector. The mechanism is operated in closed loop by means of redundant control electronics. MWHS is a sounding radiometer for measurement of global atmospheric water vapour profiles. An Engineering Qualification Model was developed and qualified and a first Flight Model was launched early 2008. The system is now working for more than two years successful in orbit. A second Flight Model of the Antenna Scanning Mechanism and of its associated control electronics was built and delivered to the customer for application on the follow-on spacecraft that will be launched by the end of 2010

Cargo of Birds to Arkansas, the Hurricanes in 2008 and the Swept Clean Hypothesis

Three hurricanes in the hurricane season of 2008 brought to Arkansas several unusual marine and other birds from southerly locations. There were 10 species noted, totaling 44 individual birds. Sooty Terns, numbering 15, were the most numerous. Laughing Gulls were next in abundance. In the mix of birds there was only 1 new species for the state, a Least Grebe. The hurricanes brought vastly different cargos of birds, and two hypotheses relating to how hurricanes transport birds are proposed. The findings supported the swept clean hypothesis over the blown through hypothesis

Integrating Fiber Optic Strain Sensors into Metal Using Ultrasonic Additive Manufacturing

Ultrasonic additive manufacturing, a rather new three-dimensional (3D) printing technology, uses ultrasonic energy to produce metallurgical bonds between layers of metal foils near room temperature. This low temperature attribute of the process enables integration of temperature sensitive components, such as fiber optic strain sensors, directly into metal structures. This may be an enabling technology for Digital Twin applications, i.e., virtual model interaction and feedback with live load data. This study evaluates the consolidation quality, interface robustness, and load sensing limits of commercially available fiber optic strain sensors embedded into aluminum alloy 6061. Lastly, an outlook on the technology and its applications is described

clinical homogeneity and allelic heterogeneity in seven patients

Background Larsen syndrome is an autosomal dominant skeletal dysplasia characterized by large joint dislocations and craniofacial dysmorphism. It is caused by missense or small in-frame deletions in the FLNB gene. To further characterize the phenotype and the mutation spectrum of this condition, we investigated seven probands, five sporadic individuals and a mother-son-duo with Larsen syndrome. Methods The seven patients from six unrelated families were clinically and radiologically evaluated. All patients were screened for mutations in selected exons and exon-intron boundaries of the FLNB gene by Sanger sequencing. FLNB transcript analysis was carried out in one patient to analyse the effect of the sequence variant on pre-mRNA splicing. Results All patients exhibited typical facial features and joint dislocations. Contrary to the widely described advanced carpal ossification, we noted delay in two patients. We identified the five novel mutations c.4927G > A/p.(Gly1643Ser), c.4876G > T / p.(Gly1626Trp), c.4664G > A / p.(Gly1555Asp), c.2055G > C / p.Gln685delins10 and c.5021C > T / p.(Ala1674Val) as well as a frequently observed mutation in Larsen syndrome [c.5164G > A/p.(Gly1722Ser)] in the hotspot regions. FLNB transcript analysis of the c.2055G > C variant revealed insertion of 27 bp intronic sequence between exon 13 and 14 which gives rise to in-frame deletion of glutamine 685 and insertion of ten novel amino acid residues (p.Gln685delins10). Conclusions All seven individuals with Larsen syndrome had a uniform clinical phenotype except for delayed carpal ossification in two of them. Our study reveals five novel FLNB mutations and confirms immunoglobulin-like (Ig) repeats 14 and 15 as major hotspot regions. The p.Gln685delins10 mutation is the first Larsen syndrome-associated alteration located in Ig repeat 5. All mutations reported so far leave the filamin B protein intact in accordance with a gain-of-function effect. Our findings underscore the characteristic clinical picture of FLNB-associated Larsen syndrome and add Ig repeat 5 to the filamin B domains affected by the clustered mutations

Musical activities in Salem, Massachusetts: 1783-1823

Thesis (Ph.D.)--Boston UniversityVery little is known to date of the musical life in America during the transitionary period extending from roughly the last quarter of the eighteenth century through the first quarter of the nineteenth century. Musical life in New England would seem to have started with psalmody in the eighteenth century and then have skipped to public school music in the late 1830's, with a few native composers and itinerate singing masters bridging the two eras. However, the larger communities bordering the whole eastern seaboard developed an urbane society which readily sought to emulate English Continental musical life. Salem, during this transitionary period, was the second largest community in Massachusetts and one of the major seaports in America. As a direct result of maritime commerce, Salem became one of the wealthiest towns in America; and, as such, experienced a sophisticated society which actively supported a musical life, equal in quality to almost any in America. It was the purpose of this dissertation (1) to present a detailed picture of the musical life in Salem, Massachusetts, from the years 1783 to 1823; (2) to identify the significant musical events, personalities, and musical organizations existing during this period, and by so doing; (3) to emphasize a facet of musical performance during this period of American History.

Zuflucht, Anerkennung und "heimisch werden" - Herausforderungen aktueller (Bildungs-) Politik in didaktischer, kinder- und jugendliterarischer und pädagogischer Perspektive

Alles in allem steht die deutsche Gesellschaft heute sowie in den nächsten Jahren vor der großen Herausforderung viele geflüchtete Menschen in unsere Gesellschaft zu integrieren. Die Aufnahme der Geflüchteten war dazu nur ein erster, wichtiger Schritt. Dazu werden sowohl Konzepte im Rahmen der Bildung als auch in der Berufswelt benötigt – es erfordert jedoch auch, entsprechende Vorurteile abzubauen, offen zu sein für diese Menschen und neue Erfahrungen, sodass wir hoffen, dass Angela Merkel mit dem Satz „Wir schaffen das!“ Recht behalten wird
