Multi-parameter approximation of stress field in a cracked specimen using purpose-built Java applications

A quality of multi-parameter approximation of the stress and displacement fields around a crack tip in a non-brittle material test specimen is studied in the paper. The stress field approximation using Williams power series is intended to be utilized for estimation of the nonlinear zone extent which potentially plays a role within methods for determination of true values of fracture parameters of materials exhibiting nonlinear failure. Considering the fact that in the case of elastic-plastic and especially quasi-brittle materials the size of this zone is substantial in comparison to the specimen dimensions, it is necessary to take a large region around the crack tip into account for this task. An automatic utility created to determine the values of coefficients of the higher order terms of Williams power series by usage of over-deterministic method applied on results of finite element analysis of arbitrary mode I test geometry is one of the tested procedures. The second one provides a backward reconstruction of the crack-tip stress field analytically by means of truncated Williams expansion. The developed procedures are based on the support of Java programming language and considerably simplify analyses of the mechanical fields' description in a farther distance from the crack-tip. The presented research is focused on optimization of selection of FE nodal results for improvement of accuracy of the approximation.
Institutional Versus Academic Discipline Measures of Student Experience: A Matter of Relative Validity

The University of California’s census survey of undergraduates, UCUES, presents an opportunity to measure both disciplinary and institutional differences in students’ academic experience. Results from nearly 60,000 responses (38% response rate) from the 2006 administration found greater variance among majors within an institution than between equivalent majors across institutions. Cluster analysis techniques were employed to establish disciplinary patterns, with traditional distinctions between hard and soft sciences generally supported. Reporting practices called into question range from institutional comparisons that ignore academic program mix and discipline to campus performance comparisons that do not recognize pedagogical differences by academic major. More specifically, these results suggest that calls for comparable institutional performance measures, as proposed by the Spellings Commission, must take into consideration disciplinary differences in instruction.
Influence of Prior Distributions and Fragility assessment methods in the estimation of the Magnitude of a Historical Seismic Event

The production of fragility functions describing the probable behaviour and damage on historical buildings is a key step in a method for the estimation of the magnitude of historical seismic events that uses a Bayes'. The fragilities are estimated by integrating the structural capacity with the seismic demand using either static methods, as the Capacity Spectrum Method (CSM), or dynamic methods, as Incremental Dynamic (IDA) and Multiple Stripes Analysis (MSA). Uncertainties in both resistance, demand, and distance and magnitude models propagate to the posterior magnitude distribution. The present paper studies the effect of uncertainties related both to the production of fragility functions and prior distributions, in the estimation of the magnitude of the 1763 Komarom earthquake (in historical Hungary). In the XVIII century most of the structures in the region were built of earth, adobe, clay or stone masonry, which is complex to model. While micro or detailed macro-modelling strategies are computationally costly, simplified macro-approaches are often more efficient, but require a pre-identification of the failure mode(s) and the determination of the backbone curve. For this study, a simplified macro-model of a Hungarian peasant house archetype is calibrated for CSM and IDA. The physical and geometrical uncertainties are incorporated in the fragilities using Monte-Carlo simulation. Prior magnitude and distance distributions are studied. The final magnitude estimates are presented and discussed.
Vorticity-transport and unstructured RANS investigation of rotor-fuselage interactions

The prediction capabilities of unstructured primitive-variable and vorticity-transport-based Navier-Stokes solvers have been compared for rotorcraft-fuselage interaction. Their accuracies have been assessed using the NASA Langley ROBIN series of experiments. Correlation of steady pressure on the isolated fuselage delineates the differences between the viscous and inviscid solvers. The influence of the individual blade passage, model supports, and viscous effects on the unsteady pressure loading has been studied. Smoke visualization from the ROBIN experiment has been used to determine the ability of the codes to predict the wake geometry. The two computational methods are observed to provide similar results within the context of their physical assumptions and simplifications in the test configuration.
A 53-Year History of Spectrum Efficiency Studies and Recommended Future Directions

Spectrum is a limited resource upon which the world makes continually increasing demands. It is therefore natural and compelling to study the efficiency with which radio systems use spectrum. Spectrum efficiency studies reveal how future systems can make better use of radio spectrum, and allow spectrum engineers and managers to make better allocation and sharing decisions. This report provides a 53-year historical review of previous domestic and international spectrum efficiency studies. Based on this review, we recommend possible future spectrum efficiency work to extend the state of knowledge in this area.
The ATCA/VLA OH 1612 MHz survey. I. Observations of the galactic bulge Region

We present observations of the region between j' j10 and jb j 3 in the OH 1612.231 MHz line, taken in 1993 October and November with the Australia Telescope Compact Array 1 . The region was systematically searched for OH/IR stars and was covered completely with 539 pointing centres separated by 30 0 . T he size of the dataset calls for a special reduction technique that is fast, reliable and minimizes the output (positions and velocities of possible stars only). Having developed such a reduction method we found 307 OH masing objects, 145 of which are new detections. Out of these, 248 have a standard double-peaked spectral prole, 55 a single-peaked prole and 4 have nonstandard or irregular proles. In this ar- ticle we analyse the data statistically and give classica- tions and identications with known sources where pos- sible. The astrophysical, kinematical, morphological and dynamical properties of subsets of the data will be ad- dressed in future articles. These observations are part of a larger survey, coveringj'j45 andjbj 3 ,w ith the Australia Telescope Compact Array and the Very Large Array.

Handbook of Research on Emerging Technologies for Architectural and Archaeological Heritage

In the last years 3D scanning has become an important resource in many fields, in particular it has played a key role in study and preservation of Cultural Heritage. Moreover today, thanks to the miniaturization of electronic components, it has been possible produce a new category of 3D scanners, also known as handheld scanners. Handheld scanners combine a relatively low cost with the advantage of the portability. The aim of this chapter is two-fold: first, a survey about the most recent 3D handheld scanners is presented. As second, a study about the possibility to employ the handheld scanners in the field of Cultural Heritage is conducted. In this investigation, a doorway of the Benedictine Monastery of Catania, has been used as study case for a comparison between stationary Time of Flight scanner, photogrammetry-based 3D reconstruction and handheld scanning. The study is completed by an evaluation of the meshes quality obtained with the three different kinds of technology and a 3D modeling reproduction of the case-study doorway.

Giving According to Preferences: Decision-Making in the Group Dictator Game

We study the decision process in a group dictator game in which three subjects can distribute an initial endowment between themselves and a group of recipients. The experiment consists of two stages; first, individuals play a standard dictator game. Second, individuals are randomly matched into groups of three and communicate via instant messaging regarding the decision in the group dictator game. In contrast to former studies our results show that group decisions do not differ from individual decisions in the dictator game. Furthermore, the analysis of the chat history reveals that players make proposals according to their preferences as revealed in the single dictator game and that these proposals in groups drive the final allocation. This paper has been published 2014 in Soziale Welt 65(1): 139-156 (see http://www.soziale-welt.nomos.de/archiv/2014/heft-2/).
Minimum Time Required to Detect Population Trends: The Need for Long-Term Monitoring Programs

Long-term time series are necessary to better understand population dynamics, assess species' conservation status, and make management decisions. However, population data are often expensive, requiring a lot of time and resources. What is the minimum population time series length required to detect significant trends in abundance? I first present an overview of the theory and past work that has tried to address this question. As a test of these approaches, I then examine 822 populations of vertebrate species. I show that 72% of time series required at least 10 years of continuous monitoring in order to achieve a high level of statistical power. However, the large variability between populations casts doubt on commonly used simple rules of thumb, like those employed by the IUCN Red List. I argue that statistical power needs to be considered more often in monitoring programs. Short time series are likely under-powered and potentially misleading.
Determination of Orifice Coefficients for Flow Through Circular and Rectangular Orifices

Circular and rectangular orifices are among the types of orifices being classified according to geometrical shapes. They are among others widely used as flow meters. Knowledge about the orifice coefficients and discharges through circular and rectangular orifice is very important, when selection for use is based on the requirement of low or high discharges as well as high or low orifice coefficients. So, this research work experimentally determined the orifice coefficients and discharges through circular and rectangular orifices having the same area of 0.00015m 2 under a constant head of water of 0.9m. The experimental results revealed that under a constant head of water of 0.9m, circular orifice has average coefficient of discharge, coefficient of velocity, coefficient of contraction, theoretical and actual discharges as 0.62, 0.94, 0.66, 5.52x 10 -4 m 3 /s and 3.42x 10 -4 m 3 /s respectively. More so, that rectangular orifice under the same constant head of water of 0.9m, has average coefficient of discharge, coefficient of velocity, coefficient of contraction, theoretical and actual discharge as 0.66, 0.96, 0.69, 5.53x10 -4 m 3 /s and 3.65 x10 -4 m 3 /s respectively.
Effect of Vermicompost, Pistachio Kernel and Shrimp Shell on Some Growth Parameters and Availability of Cd, Pb and Zn in Corn in a Polluted Soil

This experiment was conducted to evaluate the effect of vermicompost, pistachio kernel and shrimp shell on the immobilization and availability of Cd, Pb and Zn in corn in polluted soils. Treatments consisted of two levels of pistachio kernel, shrimp shell and vermicompost (5 and 10 % w/w). In control treatment, no amendment was added to the soil. The experiment was carried out as a completely randomized design with 3 replications. Plants grew for two months in the greenhouse. Then, all the plants were harvested and their shoots and roots were separated, washed with distilled water and oven dried at 65 °C to a constant mass. The measured characteristics were dry weight of shoots and roots, leaf area, greenness index, chlorophyll fluorescence, maximal quantum yield of PS photochemistry (Fv/Fm), performance index (PI), and total concentrations of Cd , Pb and Zn in shoots and roots. Results showed that plant growth parameters (dry weight of shoots and roots, leaf area) and photosynthetic characteristics (chlorophyll fluorescence, Fv/Fm, and PI) were higher in plants grown in vermicompost and pistachio kernel treatments as compared to those grown in control. Plants died in shrimp shell treatment after two weeks. The concentration of Cd, Zn and Pb in shoots and roots of plants grown in vermicompost and pistachio kernel treatments were lower than those grown in control.
Fraction number line tasks and the additivity concept of length measurement

The performance of 29 Grade 6 children on eight number line tasks is descriptively analysed with regard to three types of misconceptions. The first is conceptual; over-generalised part-whole unit-forming. The other two are semiotic misreadings of inscriptions, namely counting lines and decimalising. Success on these number line tasks, possible examples of the measure sub-construct of fractions, is descriptively compared to the children’s performance on tasks assessing conservation and the additivity concept of length measurement, and on multiplication and division items.
A note on Grothendieck's standard conjectures of type C and D

Grothendieck conjectured in the sixties that the even Kunneth projector (with respect to a Weil cohomology theory) is algebraic and that the homological equivalence relation on algebraic cycles coincides with the numerical equivalence relation. In this note we extend these celebrated conjectures from smooth projective schemes to the broad setting of smooth proper dg categories. As an application, we prove that Grothendieck's original conjectures are invariant under homological projective duality. This leads to a proof of Grothendieck's conjectures in the case of intersections of quadrics, linear sections of determinantal varieties, and intersections of bilinear divisors. Along the way, we prove also the case of quadric fibrations.
Medical Versus Surgical Management Of Native Joint Septic Arthritis In Adults: A Retrospective Comparison Of Outcomes Within The Va Ct Medical System

Objective: Septic arthritis is a medical emergency with significant associated morbidity and mortality that requires joint drainage in addition to antibiotic therapy. Closed-needle aspiration and surgery (via arthrotomy or arthroscopy) are the standard approaches to joint drainage, though little data exists regarding treatment outcomes with each approach. We compared long-term outcomes for adult patients with septic arthritis of a native joint based on whether they received a ‘medical’ or ‘surgical’ approach to joint drainage. Methods: We retrospectively reviewed all chart records for patients diagnosed with septic arthritis at the West Haven VA Medical Center between January 2006 and December 2015. Treatment outcomes were recorded at one year post-diagnosis. Results: Sixty-two patients were diagnosed with native joint septic arthritis during the study period, 19 who were managed medically and 43 surgically. There was no significant difference in demographic variables, risk factors, clinical presentation, laboratory parameters, or duration of antibiotic therapy between the two groups. 81% of medically-managed patients and 82% of surgically-managed patients achieved a full recovery within 12 months. Overall mortality was 3.2%, and both patients who died were managed surgically. There were no significant predictors of poor treatment outcome aside from Black race. Conclusion: Our findings suggest that medical management of septic arthritis with closed-needle aspiration is non-inferior to surgical management in terms of both morbidity and mortality. Given the small sample size, a prospective randomized control trial is needed to guide definitive recommendations on the best form of joint drainage.

Juglans regia Provenance Research by Molecular, Morphological and Biochemical Markers: A Case Study in Italy

In the current climate change scenarios, the choice of seed sources is one of the main factors affecting the establishment and productivity of plantations of forest trees. Juglans regia L. (walnut) is one of the more valuable hardwood species since it could provide high quality timber and fruits. The aim of this study was to search peculiar Italian walnut provenances as putative biodiversity sources for seed orchards and to establish new hardwood plantations. A multidisciplinary approach, integrating molecular markers (ISSR), seed morphological traits (equatorial and polar diameter, shape, dry weight) and fruit composition (total oil, fatty acids, tocopherol) was applied to analyze samples collected in ten sites (three in Campania and seven in Abruzzo regions) and samples of four varieties (two from Southern and two from Northern Italy). Eleven selected ISSR primers exhibited a strong ability to discriminate walnut provenances.
Antitumor Effect of Bacillus Calmette-Guérin in Bladder Cancer

Bacillus Calmette-Guerin (BCG) is currently the standard therapy for treating high grade non-invasive bladder cancer. BCG is superior to intravesical chemotherapy. The antitumor effect of BCG seems to be related to cellular immunological mechanisms. However, its precise mode of action is unknown. High-risk non-invasive bladder tumors in patients will progress to muscle-invasive bladder cancer despite BCG treatment. Traditional prognostic factors are mainly based on histopathological characteristics. However, there are no clear definitive markers for the response to therapy, partly because of a lack of knowledge concerning the mechanism of action utilized by BCG to mediate the observed clinical response. In response to the inflammatory process, the urothelial and tumor cells upregulate the expression of important surface proteins, such as major histocompatibility antigens, adhesion molecules, and death receptors. These proteins might serve as markers and potential therapeutic targets to enhance BCG efficacy. The genetic and molecular changes that occur in transitional cell carcinoma (TCC) of the bladder are numerous. Recent advances in carcinogenesis research will permit the discovery of new markers in patients treated with BCG that are directly involved in the pathogenesis of bladder cancer. Further investigations of the antitumor effect of intravesical BCG will lead not only to a potential enhancement of the BCG response, but probably also to a better understanding of bladder carcinogenesis.
Numerical Analysis Method considering Coupled Effects of THMC Multifields on Unsaturated Expansive Soil Subgrade Treated with Lime

The response model subjected to coupled effect of thermo-hydro-mechano-chemical (THMC) was built in the context of basic theories in the polyporous polyphasic medium mechanics, the mixture theory in the continuum mechanics, and the thermodynamic theories. The finite element discretization of the response model was implemented based on the Galerkin method. The processes of salt leaching and accumulating were analyzed in the numerical results. The results among the numerical results and measured results were compared and discussed. Finally, the solutes migration rule of the soil subjected to the atmosphere eluviations was revealed, and the reasonableness of the coupling model and the finite element method was proved. The agreement between the numerical and the measured results was good, which indicates that the THMC model and finite element program were useful in solving the coupling problems of unsaturated soil. Moreover, the salt dissolution process has a larger effect on the salt movement compared to that of the salt accumulation process. Comparing with the salt leaching effect caused by rainfall, the salt accumulation effect caused by evaporation was smaller.
Electric wind produced by a surface dielectric barrier discharge operating in air at different pressures: aeronautical control insights

The effects of the ambient air pressure level on the electric wind produced by a single dielectric barrier discharge (DBD) have been investigated by Pitot velocity measurements. Pressures from 1 down to 0.2 atm were tested with a 32 kVp–p 1 kHz excitation. This preliminary study confirms the effectiveness of surface DBD at low pressure. Indeed, the induced velocity is strongly dependent on the ambient air pressure level. Quite surprisingly the produced airflow presents a local maximum at 0.6 atm. The measured velocities at 1 atm and 0.2 atm are 2.5 m s−1 and 3 m s−1, respectively while 3.5 m s−1 is reached at 0.6 atm. The position of the maximal velocity always coincides with the plasma extension. Mass flow rate calculations indicate that the DBD is effective in real flight pressure conditions.
Innovative Human Resource Practice: A Synthesized Framework and Causal Model of Leader-Member Exchange, Organizational Justice, Job Satisfaction, and Organizational Citizenship Behavior

Research objectives were to determine a synthesized framework and to develop a causal model of leader-member exchange, organizational justice, job satisfaction, and organizational citizenship behavior of textile mill employees in Thailand. The study reported the responses of 619 operational employees from 77 textile mills operating in different parts of Thailand. Data were collected and analyzed with descriptive statistics using SPSS (version 11.5) and assessed with confirmatory factor analysis to confirm the heterogeneity of all constructs and path analysis to test the cause and effect relationships among main constructs of the study using LISREL (version 8) on a structured questionnaire containing standard scales of leader-member exchange, organizational justice, job satisfaction, and organizational citizenship behavior to determine the relationships of leader-member exchange, organizational justice, and job satisfaction on organizational citizenship behavior. Research findings indicated that dimensions of leader-member exchange, organizational justice, and job satisfaction have mediated positive effect on organizational citizenship behavior. Furthermore, organizational justice and job satisfaction positively mediate the relationship between leader-member exchange and organizational citizenship behavior.
