ABSTRACTResident (non‐migratory) Canada goose (Branta canadensis) populations in suburban environments pose risks to human health and safety. Specifically, the relatively large size and gregarious behavior of geese combined with an overlap in aircraft flight space pose substantial risk of property damage and human fatalities from goose‐aircraft collisions. We estimated home range and core use areas of resident Canada geese and evaluated goose movements to better define the risk of goose‐aircraft collisions around Piedmont Triad International Airport in Greensboro, North Carolina, USA. We placed satellite transmitters on 16 of 763 neck‐ and leg‐banded geese to identify and track individuals over an 18‐month study period. The frequency of satellite‐tagged goose movements peaked daily within the first 2 hours after sunrise (28.1%) and again near sunset (27.2%). All in‐flight goose movements occurred ≤64 m above ground level. Geese flying at these altitudes posed a risk to aircraft in the take‐off and landing phases of flight. For all in‐flight movements, the number of movements per day was 0.13 during the molt (1 Jun–15 Jul), 0.42 during early post‐molt 2008 (16 Jul–31 Oct), 0.36 during late post‐molt (1 Nov–31 Jan), 0.58 during breeding/nesting (1 Feb–31 May), and 0.58 during the early post‐molt 2009. Satellite‐tagged geese traveled a mean distance ranging from 2.0 km (SE = 0.3) to 4.9 km (SE = 0.4) per day, depending on sex and season, which supports the need for intensive goose management within a minimum distance of 8 km from airports. Mean fixed 95% kernel home range and 50% core use area were 991.8 ha (SE = 241.1) and 120.4 ha (SE = 24.6), respectively. Additionally, we monitored site recolonization of nuisance geese after the controlled removal of 60 resident geese from 1 site, which eliminated 24.2% of those initially banded at the site in 2008, but other geese began to recolonize the site within 27 days. Rapid recolonization of the removal site suggests that lethal removal should be conducted at all molt locations within a minimum distance of 8 km of suburban airports and any additional removal or management resources should be applied to greater distances to prevent recolonization of these sites by geese in close proximity to the removal site.

Published: July 2015

ABSTRACTIntroduction: Previous experiments have indicated that in vivo administration of ursodeoxycholic acid (UDCA) inhibits nuclear NF‐κB activation and has beneficial effects on the structure and function of dystrophic (mdx) muscle. We examined the effect of UDCA on tension development in dystrophic muscle. Methods: Isometric tension development was examined in costal diaphragms that were freshly isolated from vehicle and UDCA treated mdx mice. Percent recovery scores were obtained by directly comparing these measurements to those obtained from age‐matched nondystrophic mice. Results: Vehicle treated mdx mice exhibited significantly reduced optimal muscle lengths (lo) and specific twitch and tetanic tensions compared with age‐matched nondystrophic mice. UDCA treated preparations exhibited significantly improved tension development with a 33% recovery score. Conclusions: Because UDCA is used in treating certain clinical disorders, these results provide a rationale for human clinical trials using this and related drugs for treatment of Duchenne and related muscular dystrophies.

Achieving robust design through statistical effect screening
Authors: Van Buren Kendra L. , Hemez François M. 
Published: July 2015

SummaryThis work proposes a method for statistical effect screening to identify design parameters of a numerical simulation that are influential to performance while simultaneously being robust to epistemic uncertainty introduced by calibration variables. Design parameters are controlled by the analyst, but the optimal design is often uncertain, while calibration variables are introduced by modeling choices. We argue that uncertainty introduced by design parameters and calibration variables should be treated differently, despite potential interactions between the two sets. Herein, a robustness criterion is embedded in our effect screening to guarantee the influence of design parameters, irrespective of values used for calibration variables. The Morris screening method is utilized to explore the design space, while robustness to uncertainty is quantified in the context of info‐gap decision theory. The proposed method is applied to the National Aeronautics and Space Administration Multidisciplinary Uncertainty Quantification Challenge Problem, which is a black‐box code for aeronautic flight guidance that requires 35 input parameters. The application demonstrates that a large number of variables can be handled without formulating simplifying assumptions about the potential coupling between calibration variables and design parameters. Because of the computational efficiency of the Morris screening method, we conclude that the analysis can be applied to even larger‐dimensional problems.

ABSTRACTA new green solvent, cyclopentyl methyl ether (CPME), is used for the first time in solvent mixtures for the successful supplemental activator and reducing agent atom transfer radical polymerization (SARA ATRP) of both activated and non‐activated monomers. The SARA ATRP of methyl acrylate (MA), glycidyl methacrylate (GMA), styrene (Sty), and vinyl chloride (VC) in CPME‐based mixtures is studied and presents similar features to those reported in the literature using other SARA ATRP systems. Moreover, CPME‐based mixtures are suitable solvents for the controlled SARA ATRP of MA using different SARA agents, such as Fe(0), Cu(0), or Na2S2O4. The chemical structure and the retention of the chain‐end functionality of the polymers are confirmed by 1H NMR and MALDI‐TOF analyses and the preparation of a well‐defined PMA‐b‐PVC‐b‐PMA triblock copolymer. The method reported here presents an additional improvement in the search for new ecofriendly ATRP systems. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015, 53, 2722–2729

AbstractIn Niederfinow wird neben dem bestehenden ein zweites Schiffshebewerk errichtet. Nach umfangreichen Voruntersuchungen entschied sich die Wasser‐ und Schifffahrtsverwaltung für ein Senkrechthebewerk mit Gegengewichtsausgleich. Ein Tragwerk, bestehend aus Stahlbetontürmen, ‐stützen und Seilrollenträgern, die in einer gemeinsamen Trogwanne gegründet werden, leitet die Lasten des wassergefüllten Troges (ca. 9 800 t) über Seilrollenträger in den Untergrund ab. Der an Seilen durch Gegengewichte im Gleichgewicht gehaltene Trog erhält eine nutzbare Länge von 115 m, eine nutzbare Breite von 12,5 m und lässt eine Wassertiefe von 4,0 m zu. Die Vertikalbewegungen des Troges erfolgen mittels Zahnstangenantrieb. Ein Sicherungssystem aus Mutterbackensäulen und Drehriegeln gewährleistet ein sicheres Absetzen des Troges bei Reparatur und in Havariefällen.Im Mai 2008 wurde die Arge Neues Schiffshebewerk Niederfinow bestehend aus den heutigen Firmen Bilfinger Construction GmbH, DSD Brückenbau GmbH, Johann Bunte Bauunternehmung GmbH New ship lift at Niederfinow, Germany. A second ship lift is to be constructed in Niederfinow adjacent to the existing lift. After extensive preliminary studies, the Federal Waterways Administration decided on a vertical lift with balancing counterweights. A load‐bearing structure consisting of reinforced concrete towers, columns and cable pulley girders, all with foundations in a common trough well, transfers the loads from the water‐filled trough (9 000 t) into the bedrock via cable pulley girders. The trough, which is suspended on cables and balanced with counterweights, has a usable length of 115 m, a usable width of 12.5 m and allows a water depth of 4.0 m. Vertical movements of the trough take place by means of rack and pinion drives. A safety system consisting of internally threaded columns and rotary locking bars ensures that the trough stops safely in an emergency.In May 2008 the contract to construct the new ship lift was awarded to the consortium Neues Schiffshebewerk Niederfinow, consisting of Bilfinger Construction GmbH, DSD Brückenbau GmbH, Johann Bunte Bauunternehmung GmbH

AbstractDie Stahlkonstruktion des Troges für das neue Schiffshebewerk in Niederfinow wurde in einer komplexen Bemessung für die Betriebszustände gewichtsmäßig optimiert. Gleichzeitig mussten verschiedene außergewöhnliche Belastungszustände bei der Dimensionierung berücksichtigt werden. Die hierfür erforderlichen Berechnungen wurden an einem Finite‐Elemente‐Modell des Troges mit unterschiedlichen Lagerungsbedingungen durchgeführt. Damit die Montage der Gegengewichte nicht für die Bemessung des Troges maßgebend wird, musste ein detailliertes Ballastierungskonzept ausgearbeitet werden.Bei der Fertigung und Montage des Troges waren unter anderem die geringen zulässigen Toleranzen an den Trogenden im Bereich der Drehsegmenttore zu berücksichtigen. Durch fertigungstechnische Maßnahmen und eine anschließende mechanische Bearbeitung wurden diese Vorgaben umgesetzt.Ship lift Niederfinow – Analysis, manufacture and assembly of the trough. The steel structure of the trough for the new ship lift in Niederfinow was optimized regarding its weight by using a complex analysis of the serviceability states. At the same time several special load cases had to be taken into account in the analysis. The analysis was done on a finite element model of the trough with different bearing conditions. In order to avoid that the assembling of the counterweights will be the decisive load case a comprehensive ballasting system had to be developed.During manufacture and assembly of the trough, the low allowable tolerances at the trough ends for the installation of the rotating segment gates were taken into consideration. Manufacturing provisions and a subsequent mobile machining of the relevant plates ensured these requirements.

AbstractDie Ausführung und Qualitätssicherung des Korrosionsschutzes der Stahlbauten des Schiffshebewerkes Niederfinow erfolgt durch die strikte Umsetzung einer für alle Beteiligten geltenden Korrosionsschutzanweisung. Hier werden u. a. die vielfältigen architektonischen farblichen Anforderungen sowie die Beschichtung in mehreren Fertigungswerken und auf der Baustelle berücksichtigt. Etwa 70 % der Bauteile wurden vorkonserviert angeliefert. Nachträgliche Schweißarbeiten auf der Baustelle und deren negative Auswirkungen auf bereits beschichteten Flächen erforderten umfangreiche Qualitätsmaßnahmen. Es wurden überwiegend bewährte Korrosionsschutzsysteme eingesetzt. Für Beschichtungen im Einzelfall, Pulverbeschichtungen und auch beim Kathodischen Korrosionsschutz (KKS) für die Anoden wurden im Bereich des Verkehrswesens neue Wege beschritten.Corrosion protection at the new ship lift Niederfinow, Germany. Conducting and quality management of the anticorrosive coating of the steel constructions belonging to the ship lift in Niederfinow is ensured by a strict implementation of an anticorrosive coating instruction that is valid for all parties involved. The instruction considers the variety of architectural requirements concerning color as well as the coating in several assembly plants and at the construction site. Approximately 70 % of the devices have been delivered pre‐preserved. Subsequent conducted welding jobs at the construction site and their negative effects on the already coated surfaces demand an enormous additional quality management. Predominantly, established anticorrosive coating systems have been used. In the field of transportation, new paths haven been explored for coatings that needed individual approval, for powder coatings as well as for cathodic corrosion protection for the anodes.

The 1 : 50 scale model of the Niederfinow boat lift has enriched the permanent exhibition at the Deutsches Technikmuseum (DTM) since 8 December 2014. Around 140 000 miniature rivets, over 36 000 mostly unsalaried hours of work and countless authentic details went into the construction of this functional model. This masterpiece of model‐building consists almost entirely of brass, but also in part of steel, aluminium, plastic, wood, and lead; above all, it is the product of 20 years of tinkering, exactitude, passion, patience, ingenuity and craftsmanship. The model shows the boat lift located near Niederfinow, around 70 km north‐east of Berlin. It raises ships 36 m from the lower Oder reach to the upper canal reach and also lowers them in the other direction. It is the oldest boat lift in Germany which is still in commission today. Various models were commissioned during and prior to the building phase of this construction, which began operation in 1934. These models as well are described in brief below.

Published: July 2015

AbstractRingflanschverbindungen an Monopile‐Tragstrukturen stehen aktuell im Fokus kosteneffizienter Design‐Konzepte für Offshore‐Windenergieanlagen. Die geschraubte Verbindung zwischen Monopile und Transition Piece (Übergangsstück zum Turm der Windenergieanlage) erfordert jedoch, dass das Rammen mit einem hydraulischen Hammer direkt auf dem Monopile‐seitigen Flansch erfolgt. Der Flansch wird extremen Belastungen während des hochdynamischen Rammvorgangs ausgesetzt, wodurch hohe Vorschädigungen am Flansch sowie an der Schweißnaht zum Monopile entstehen können. Bei der Berechnung der Rammschädigungen ist, zusätzlich zum eigentlichen Hammerschlag, eine durch den Lasteintrag angeregte Schwingung am Flansch zu berücksichtigen. In diesem Artikel werden die wesentlichen Parameter einer Rammanalyse vorgestellt. Wechselwirkungen zwischen Hammer, Monopile und Boden werden mit einer eindimensionalen Wellengleichungsmethode untersucht. Das hierbei ermittelte Lastspektrum wird zur Validierung eines detaillierten Finite‐Elemente(FE)‐Modells genutzt, welches den ursprünglichen Schlag zwischen Hammer und Flansch sowie die dynamische Antwort der Pfahl‐Boden‐Interaktion im Zeitbereich simuliert. Basierend auf den Berechnungsergebnissen werden Empfehlungen für Designoptimierungen sowie Verfahren zur Bewertung der Rammschädigung vorgestellt.Determination of pile‐driving fatigue at flanges of monopile foundations. Cost‐efficient design concepts of monopile foundations for offshore wind turbines have recently focused on bolted ring flange connections. The bolted connection between the monopile and transition piece implies that the pile‐driving operation by means of a hydraulic hammer is directly performed on the flange. The highly dynamic pile‐driving loads may lead to substantial pre‐damages at the flange structure and weld. For the determination of pile‐driving fatigue, the initial hammer strike as well as an induced oscillation has to be considered. In this paper, the main parameters defining a pile‐driving analysis are presented. Basic pile‐driving effects are investigated by application of a one‐dimensional wave equation analysis. The results are used to validate a detailed finite element (FE) model which simulates the initial hammer strike as well as the dynamic response of the pile‐soil interaction. Based on the calculation results, recommendations for design optimizations and evaluation methods of pile‐driving fatigue are provided.

AbstractThe suitability of using visible/near infrared spectroscopy (Vis/NIR), as a rapid and non‐destructive technique for monitoring the quality of argan seeds (Argania spinosa Skeels) was studied. The analyzed parameters were the fatty acid composition of argan seed oil, seed moisture content, seed oil content and oil stability index (OSI). The ratio between major unsaturated and saturated fatty acids (U/S) during the oxidation assay at constant temperature was studied. Values from infrared drying were used as a laboratory reference for the moisture. Argan seed oil content was determined by Soxhlet extraction. A fatty acid analysis was carried out by gas chromatography and the OSI was determined by the Rancimat test. Predictive models of argan seed moisture, ratio U/S and OSI showed good accuracy. Therefore, Vis/NIR measurements can be used for controlling several argan seed quality parameters. This procedure might be of interest to the argan oil industry, which is currently in the process of modernization and expansion.

AbstractObjectiveTo evaluate the feasibility and satefy of transcatheter aortic valve implantation in animals by using a new balloon‐expanding valved stent.MethodsThe balloon‐expandable stent is made from cobalt‐based alloy material and designed with a tubular, slotted structure. Fresh bovine pericardium was treated, sutured and fixed on the balloon‐expandable stent. Ten healthy sheep (five males and five females), weighing an average of (25.16 ± 1.83) kg, were selected to undergo transcatheter implantation of the valve stents. The function of the valve stent was evaluated by angiography, echocardiography, and histology six months after the procedure.ResultsOf the ten experimental sheep, two sheep died during the operation because the higher position of the artificial valve affected the opening of the coronary artery. We successfully implanted the aortic valve stent in other eight sheep; however, one sheep died of heart failure two weeks after the operation due to the lower position of the valve stent. The valve stents were implanted in the desired position in seven sheep. Ascending aortic angiographic and autoptic findings immediately after the operation confirmed the satisfactory location and function of the valved stent. Echocardiography, angiography, and histology at six postoperative months confirmed the satisfactory location and function of the valve stent.ConclusionWe successfully implanted our new valve stent as a replacement of native aortic valve via the transcatheter route with satisfactory outcome.

AbstractIntroductionFreely accessible online tests for the diagnosis of Alzheimer's disease (AD) are widely available. The objective of this study was to evaluate these tests along three dimensions as follows: (1) scientific validity; (2) human‐computer interaction (HCI) features; and (3) ethics features.MethodsA sample of 16 online tests was identified through a keyword search. A rating grid for the tests was developed, and all tests were evaluated by two expert panels.ResultsExpert analysis revealed that (1) the validity of freely accessible online tests for AD is insufficient to provide useful diagnostic information; (2) HCI features of the tests are adequate for target users, and (3) the tests do not adhere to accepted ethical norms for medical interventions.DiscussionThe most urgent concerns raised center on the ethics of collecting and evaluating responses from users. Physicians and other professionals will benefit from a heightened awareness of these tools and their limitations today.

AbstractBackgroundThe CAIDE (Cardiovascular Risk Factors, Aging, and Incidence of Dementia) Dementia Risk Score is a validated tool to predict late‐life dementia risk (20 years later), based on midlife vascular risk factors. The goal was to render this prediction tool widely accessible.MethodsThe CAIDE Risk Score (mobile application) App was developed based on the CAIDE Dementia Risk Score, involving information on age, educational level, hypertension, hypercholesterolemia, obesity, and physical inactivity.ResultsThe CAIDE Risk Score App is an evidence‐based practical tool, which allows users to detect their individual risk, provides guidance for risk modification, and suggests consulting a health care practitioner if needed. Moreover, it allows practitioners to discuss preventive measures and monitor risk reduction.ConclusionsThe CAIDE Risk Score App is the first to predict the risk for dementia through an important evidence‐based tool. The App can encourage users to actively decrease their modifiable risk factors and postpone cognitive impairment and dementia.
