Published: February 2017

Zusammenfassung
Es wird ein Ultraschallmikroskop zur zerstörungsfreien Untersuchung
gekrümmter Prüflinge vorgestellt. Kommerziell erhältliche
Ultraschallmikroskope sind lediglich für die Untersuchung an ebenen
Oberflächen konzipiert. Sie verfügen über ein Verfahrsystem aus zwei
Linearachsen, das den Ultraschallprüfkopf während der Messung lateral
über den Prüfling bewegt. Um bei Prüflingen mit gekrümmter Oberfläche
eine optimale Bildqualität zu erzielen, muss der Prüfkopf so justiert
werden, dass er an jedem Messpunkt orthogonal auf deren Oberfläche
schallt. Im vorgestellten Messaufbau wurde dazu ein hochpräziser
Roboter integriert, der über sechs Bewegungsfreiheitsgrade
verfügt. Dadurch ist es möglich, neben der mäanderförmigen Abtastung
durch den Ultraschallprüfkopf eine zusätzliche Winkelnachführung des
Prüflings durchzuführen. In diesem Beitrag wird das entwickelte
Ultraschallmikroskop in Aufbau und Funktion beschrieben. Die
Auflösungsgrenzen im resultierenden Bild sowie die erreichbare
Positioniergenauigkeit des Verfahrsystems werden beleuchtet. Zudem
wird das Potential des Systems anhand einiger Messungen an
exemplarischen Prüflingen aufgezeigt.

The need for monitoring, effective and efficient control and evaluation of water quality in regional waters Surabaya become a demand for population growth, climate change and variability in the current era of urbanization. The traditional method is done by collecting water samples, test and analyze water in the laboratory has been relatively expensive and do not have the ability to capture real-time data, analysis and information delivery fast in making decisions. On the other hand, the rapid spread in the use of mobile phones in developing countries has increased mobile data management applications. A variety of mobile applications has also increased in recent years. This is because mobile phones cheap, easy to use and can transmit multiple types of information including images and GPS data remotely. In this paper, the author describes a data communication system of water quality resources based on UDP protocol. This system is called ubiquitous mobile sensing consisting of microcontroller Arduino, water quality sensors, and Android smartphones. It has the ability to detect temperature, dissolved oxygen (DO), pH and electrical conductivity (EC) in real time. By using this monitoring system, the data result is expected more accurate, faster and cheaper.

Study Design Historical cohort study. Background History of a knee joint injury and increased fat mass are risk factors for joint disease. Objective The objective of this study was to examine differences in adiposity, physical activity, and cardiorespiratory fitness between youths with a 3- to 10-year history of sport-related intra-articular knee injury and uninjured controls. Methods One hundred young adults (aged 15–26 years; 55% female) with a sport-related intra-articular knee injury sustained 3 to 10 years previously and 100 controls matched for age, sex, and sport, who had no history of intra-articular knee injury, were recruited. Fat mass index (FMI) and abdominal fat (fat mass at the L1 to L4 vertebral levels) were derived using dual-energy X-ray absorptiometry. Physical activity and cardiorespiratory fitness were measured using the Godin Leisure-Time Exercise Questionnaire and the multistage 20-meter shuttle run test for aerobic fitness, respectively. Results Previously injured participants demonstrated higher FMI (within-pair difference, 1.05 kg/m2; 95% confidence interval [CI]: 0.53, 1.57) and abdominal fat (461 g; 95% CI: 228, 694) than uninjured controls. In multivariable linear regression analysis, previous injury was significantly associated with increased FMI. This increase was attenuated in those who participated in higher levels of physical activity or had higher estimated maximum volume of oxygen. Conclusion As a risk factor for osteoarthritis in an already susceptible group, excess adiposity is an undesirable trait in the potential pathway to joint disease. Increasing physical activity in this population may be a potential intervention to reduce adiposity thus impede disease initiation and/or progression. Level of Evidence Level 2b.

Workers’ compensation claims not reported in the Survey of Occupational Injuries and Illnesses: Injury and claim characteristics
Authors: Wuellner Sara E. , Adams Darrin A. , Bonauto David K. 
Published: February 2017

BackgroundUnderreporting in the nation's primary source of non‐fatal occupational injury and illness data are well documented, but worker‐level characteristics of unreported cases have not been fully explored.MethodsBureau of Labor Statistics’ Survey of Occupational Injuries and Illnesses (SOII) data were linked to Washington workers’ compensation claims to identify injury and claim characteristics associated with unreported cases. Workers’ compensation administrative date data were used to characterize timing of disability and SOII case eligibility.ResultsBased on claim date data, one in five lost time claims with an injury date in the survey year were likely ineligible for SOII case reporting during the survey year. Among SOII‐eligible claims, those involving sprains or strains, employer protests, and those not eligible for work disability payments until months after the initial injury were least likely to be reported in SOII.ConclusionsSOII case capture is limited both by its cross sectional survey design and employer underreporting.

AbstractBackgroundSilicosis is a progressive lung disease resulting from the inhalation of respirable crystalline silica. Lung transplantation is the only treatment for end‐stage silicosis. The aim of this study was to analyze the survival experience following lung transplantation among patients with silicosis.MethodsWe reviewed data for all patients who underwent lung transplantation for silicosis and a matched group undergoing lung transplantation for idiopathic pulmonary fibrosis (IPF) at a single medical center between March 2006 and the end of December 2013. Survival was followed through 2015.ResultsA total of 17 lung transplantations were performed for silicosis among 342 lung transplantations (4.9%) during the study period. We observed non‐statistically significant survival advantage (hazard ratio 0.6; 95%CI 0.24–1.55) for those undergoing lung transplantation for silicosis relative to IPF patients undergoing lung transplantation during the same period.ConclusionsWithin the limits of a small sample, survival in silicosis patients following lung transplantation was not reduced compared to IPF.

The path to ultrasound proficiency: A systematic review of ultrasound education and training programmes for junior medical practitioners
Authors: Dickson Robert , Duncanson Kerith , Shepherd Shamus 
Published: February 2017

AbstractBackgroundPoint‐of‐care ultrasound (POCUS) is a form of diagnostic ultrasonography, which has a defined role as a clinical adjunct in patient assessment and management. If it is to continue to develop as a core clinical skill, junior medical practitioners and trainees may benefit from dedicated ultrasound education and familiarisation early in their training. Controversy endures, however, as inappropriate use of this highly technical and operator‐dependent imaging modality has negative clinical implications.AimsA systematic review was performed to assess the ability of doctors in training to perform clinically appropriate and beneficial diagnostic ultrasound after undergoing a formal training programme.MethodsStudies meeting pre‐defined inclusion criteria were identified in electronic databases MEDLINE, EMBASE, CINAHL, PUBMED and through Google Scholar. Methodological quality was assessed using an established series of indicators.ResultsFifteen studies were included in the review. Ten of these were performed in the United States, and eight focused on emergency medicine trainees. After the teaching intervention, ten studies assessed overall ultrasound capacity by calculating the collective sensitivity and specificity of trainee‐performed ultrasound. Five studies used a standardised objective assessment tool to evaluate ultrasound skills and technique. Studies varied in terms of the specific ultrasound use investigated, teaching programmes used and methodological quality. Consistently identified areas for further research included the definition of the trainee learning curve and what constitutes competency in ultrasound.ConclusionsUltrasound can feasibly be incorporated into junior medical practitioner training, but more research is required to assess its effectiveness and appropriateness.
A Reactive, Rigid GdIII Labeling Tag for In‐Cell EPR Distance Measurements in Proteins

Published: February 2017

AbstractThe cellular environment of proteins differs considerably from in vitro conditions under which most studies of protein structures are carried out. Therefore, there is a growing interest in determining dynamics and structures of proteins in the cell. A key factor for in‐cell distance measurements by the double electron–electron resonance (DEER) method in proteins is the nature of the used spin label. Here we present a newly designed GdIII spin label, a thiol‐specific DOTA‐derivative (DO3MA‐3BrPy), which features chemical stability and kinetic inertness, high efficiency in protein labelling, a short rigid tether, as well as favorable spectroscopic properties, all are particularly suitable for in‐cell distance measurements by the DEER method carried out at W‐band frequencies. The high performance of DO3MA‐3BrPy‐GdIII is demonstrated on doubly labelled ubiquitin D39C/E64C, both in vitro and in HeLa cells. High‐quality DEER data could be obtained in HeLa cells up to 12 h after protein delivery at in‐cell protein concentrations as low as 5–10 μm.

Published: February 2017

AbstractIm Zuge von Sanierungsarbeiten in Kirchenräumen kommt es oft zu Veränderungen der raumakustischen Qualität dieser Räume und leider auch zu Verschlechterungen der Raumakustik. Eine solche subjektiv als Verschlechterung empfundene Veränderung wurde nach Abschluss der (nicht akustisch beratenen) Sanierungsarbeiten im Jahr 2014 auch bei der Stadtkirche St. Michael zu Jena durch die Kirchengemeinde festgestellt. Aus diesem Grund wurden im Anschluss an die Sanierungsarbeiten auf Initiative der Kirchengemeinde 2015 im Rahmen einer Masterarbeit im Studiengang „Bauphysik und energetische Gebäudeoptimierung” an der Bauhaus‐Universität Weimar Untersuchungen zu einem Konzept zur Verbesserung der raumakustischen Qualität des Kircheninnenraumes für Musikdarbietungen erarbeitet. Für die Masterarbeit wurden neben Analysen des raumakustischen Zustandes vor und nach der Sanierung auf Basis von Tonaufnahmen detaillierte raumakustische Messungen zur objektiven Beurteilung des raumakustischen Zustandes nach der Sanierung durchgeführt sowie die Anwendbarkeit eines statistischen Rechenmodells zur Erarbeitung möglicher Verbesserungsmaßnahmen überprüft. Nachdem der subjektive Eindruck der Gemeindemitglieder mit Hilfe der durchgeführten Analysen und Messungen grundsätzlich bestätigt werden konnte, wurden zum Abschluss der Arbeit prinzipielle raumakustische Verbesserungsmaßnahmen als Grundlage für eine nachfolgende detaillierte Auslegung erarbeitet.

Gender Makes a Difference: Investigating Consumer Purchasing Behavior and Attitudes Toward Corporate Social Responsibility Policies
Authors: Jones Raymond J. , Reilly Timothy M. , Cox Marcus Z. , Cole Brooklyn M. 
Published: February 2017

AbstractThe balance between profit maximization and corporate social responsibility (CSR) has become a strategic issue of considerable importance. A key factor in understanding this relationship is identifying consumer reactions to engaging in CSR. Prior literature suggests a gap between consumers' environmental attitudes and behaviors. This study examines this relationship and finds evidence that gender significantly influences this gap between attitudes and behaviors. Specifically, we find that for female segments of the consumer population, this gap is greatly reduced. We use social identity theory to explain this phenomenon of gender differences as they relate to CSR. Along with providing insight to CSR at the individual level with attitudes and behaviors, our findings also have implications at the firm‐ level for how organizations choose and strategically signal their CSR strategies toward specific consumer segments.

Analysis of outage probability for in‐band device‐to‐device communications underlaying cellular network
Authors: Ghavami Hossein , Shirvani Moghaddam Shahriar 
Published: February 2017

SummaryOne of the key strategies for jointly increasing throughput and optimum resource allocation in 5G is device‐to‐device (D2D) communications, which can be obtained by minimizing the outage probability considered as an objective function of optimization problem. To minimize this objective function, we found that outage probability should be modeled by jointly considering the effect of interference, noise, and multipath phenomena. In this paper, the exact formulas for outage probability of in‐band D2D communications underlying cellular network are proposed. In the proposed model, additive white Gaussian noise and Rayleigh multipath fading are considered into 2 radio resource reuse scenarios. In the first scenario, each D2D pair is allowed to reuse radio resource block of one cellular user, whereas in the second scenario, 2 resources of 2 cellular users can be reused. The proposed formulas are compared to the approximate (nonexact) ones, which models additive white Gaussian noise by a constant variance. The numerical analysis for the first and second scenarios show that the approximate formulas and respected exact ones are in accordance with simulation results in MATLAB. Moreover, based on nonorthogonal multiple access approach, 2 approximations for the nonexact and the proposed formulas are extracted, which are acceptable for multiple resource reuse scenario. As a remarkable result, simulation results show that when the distance of the D2D pair from the respected cellular user is more than 71 m (2 times greater than average distance between the D2D nodes), multiple‐reuse scenarios offer higher throughput compared to 1‐reuse scenario in an acceptable outage probability.
Subarctic‐breeding passerines exhibit phenological resilience to extreme spring conditions

Published: February 2017

AbstractThere has been relatively little study of the capacity of subarctic passerines to adjust their phenologies to rapid changes on their breeding grounds. Here, we assess variation in passerine arrival timing in Denali National Park, Alaska, from 1995 to 2015, a period that included both the warmest and coldest recorded mean spring temperatures for the park. Using an open‐population occupancy modeling approach in which arrival events are random variables, we investigated interannual variation in the arrival distribution for 10 Nearctic–Nearctic migrants, three Nearctic–Neotropical migrants, and one Palearctic migrant. Neotropical–Nearctic migrants varied in terms of the flexibility of their arrival timing, but generally showed plastic phenologies, suggesting resilience under extreme spring conditions. In comparison, Nearctic–Nearctic migrants showed similar or greater plasticity in arrival timing. A majority of species showed synchronous–asynchronous fluctuation in arrival (i.e., synchronous arrival in some years, asynchronous in others) in combination with various levels of the mean response (i.e., early, average, and late arrival), suggesting the presence of interactions between environmental conditions at multiple scales and inter‐individual variation. The presence of synchronous–asynchronous fluctuation in arrival suggests that weakening of the north–south temperature gradient under continued Arctic amplification may strongly affect arrival variances. Our results also suggest that complex interactions between distributional and phenological changes may be possible. For example, the arrival distribution of Fox Sparrow (Passerella iliaca) became more synchronized over time, a pattern that coincided with a dramatic increase in occupancy probability through expansion of its elevational distribution. Overall, our findings suggest that monitoring of the mean–variance relationship may lead to a deeper understanding of the factors shaping phenological responses.

Published: February 2017

AbstractGraphite rod (GR) modified with electrochemicaly deposited gold nanoparticles (AuNPs) and adsorbed glucose oxidase (GOx) was used in amperometric glucose biosensor design. Enzymatic formation of polypyrrole (Ppy) on the surface of GOx/AuNPs/GR electrode was applied in order to improve analytical characteristics and stability of developed biosensor. The linear glucose detection range for Ppy/GOx/AuNPs/GR electrode was dependent on the duration of Ppy‐layer formation and the linear interval was extended up to 19.9 mmol L−1 after 21 h lasting synthesis of Ppy. The sensitivity of the developed biosensor was determined as 21.7 μA mM−1 cm−2, the limit of detection – 0.20 mmol L−1. Ppy/GOx/AuNPs/GR electrodes demonstrated advanced good stability (the t1/2 was 9.8 days), quick detection of glucose (within 5 s) in the wide linear interval. Additionally, formed Ppy layer decreased the influence of electroactive species on the analytical signal. Developed biosensor is suitable for the determination of glucose in human serum samples.

Abstract

Ionic liquids are a group of chemical compounds with chemical properties that are of great interest to various fields of science and industry. However, commercial use of these substances raises concern because they may threaten the natural ecosystems. The present study used 2 types of (−)-menthol-containing imidazolium chiral ionic liquids: 1-[(1R,2S,5R)-(−)-menthoxymethyl]-3-methylimidazolium hexafluorophosphate [Im-Men][PF6] and 1-[(1R,2S,5R)-(−)-menthoxymethyl]-3-methylimidazolium trifluoroacetate [Im-Men][CF3CO2]. The effects of these compounds on growth and development of spring barley (Hordeum vulgare) and common radish (Raphanus sativus L. subvar. radicula Pers.) were investigated. The present study demonstrated that chiral ionic liquids produced a relatively high phytotoxicity, by shortening the plants’ lengths and roots, thus causing a decline in the experimental plants’ fresh weights. The investigated ionic liquids also led to a reduction in photosynthetic pigment levels, changes in hydrogen peroxide and malondialdehyde content, and changes in the activities of superoxide dismutase, catalase, and peroxidase in both plants. Changes in these enzymes were used to indicate oxidative stress levels in spring barley and common radish. It was demonstrated that imidazolium ionic liquid–induced phytotoxicity depended largely on the type of anion. The liquid [Im-Men][PF6] exhibited higher toxicity toward spring barley and common radish seedlings. Common radish was more resistant to chiral ionic liquids.
