A viscoelastic-viscoplastic-damage constitutive model based on a large strain hyperelastic formulation for amorphous glassy polymers

The aim of this work is to develop an efficient large-strain hyperelastic constitutive model for amorphous polymers in the glassy state. These materials exhibit a complex rate-and pressure-sensible behavior in both elastic and plastic regimes. After an initial linear elastic region, a nonlinear stage continues until reaching a peak stress, which is followed by a softening stage. At large strains, when the softening is saturated, a re-hardening stage is reached. The viscoelastic effect is captured using the generalized Maxwell model. The viscoplastic effect is considered using a Perzyna-type flow rule incorporating a pressure sensitive yield surface and a non-associated flow potential. This yield surface is extended from the Drucker-Prager one. The saturated softening phenomenon is modeled using an isotropic numerical damage variable progressed by a saturated softening law. With the introduction of the damage parameter, a non-local implicit gradient damage model is used to avoid the loss of the solution uniqueness. Through experimental comparisons, it is shown that the proposed model has the ability to model the complex mechanical responses of amorphous glassy polymers
Determination of the best canopy gap area on the basis of soil characteristics using the Analytical Hierarchy Process (AHP)

The assessment of canopy gap areas on the basis of soil characteristics in forest ecosystems could be one of benefit points for management of forests. This research was conducted in 20 ha areas of Experimental Forest Station of Tarbiat Modares University that is located in a temperate forest of Mazandaran province in the north of Iran. Twenty one canopy gaps with different areas were found in studied areas and classified as small (85.12 m 2 ), medium (325.21 m 2 ), large (512.11 m 2 ) and very large (723.85 m 2 ) gaps. These areas classes of canopy gaps were assessed with respect to nine criteria (soil pH, carbon to nitrogen ratio, cation exchange capacity, phosphorus, potassium, calcium, nitrogen mineralization, microbial respiration and earthworm’s biomass). Soil samples (0– 45 cm depth from the gap center and edge positions) were measured in the laboratory. The Analytical Hierarchy Process (AHP) was used for assessment of canopy gap areas. This method is widely used the Multiple Criteria Decision Support (MCDS) method and perhaps the most popular in many fields, including natural resource management, especially in forest sciences. Results of AHP indicate that the maximum of local priority belongs to small areas of canopy gaps when considering all soil characteristics. However, medium, large and very large canopy gap areas have priorities, respectively. The calculated overall priority showed that with respect to considered criterias, small and medium gap areas have higher, more ideal condition in comparison to large and very large areas. AHP results emphasise that considering soil characteristics canopy gap areas should be less than 400 m 2 in Hyrcanian forests of Iran. Also, AHP can be introduced as an effective instrument in decision-making processes for investment planning and prioritization in compliance with environmental regulations.
The Drosophila Hedgehog receptor component Interference hedgehog (Ihog) mediates cell–cell interactions through trans-homophilic binding

Hedgehog (Hh) signaling is crucial for establishing complex cellular patterns in embryonic tissues and maintaining homeostasis in adult organs. In Drosophila, Interference hedgehog (Ihog) or its close paralogue Brother of Ihog (Boi) forms a receptor complex with Patched to mediate intracellular Hh signaling. Ihog proteins (Ihog and Boi) also contribute to cell segregation in wing imaginal discs through an unknown mechanism independent of their role in transducing the Hh signal. Here, we report a molecular mechanism by which the Ihog proteins mediate cell–cell interactions. We found that Ihog proteins are enriched at the site of cell–cell contacts and engage in trans-homophilic interactions in a calcium-independent manner. The region that we identified as mediating the trans-Ihog–Ihog interaction overlaps with the Ihog–Hh interface on the first fibronectin repeat of the extracellular domain of Ihog. We further demonstrate that Hh interferes with Ihog-mediated homophilic interactions by competing for Ihog binding. These results, thus, not only reveal a mechanism for Ihog-mediated cell–cell interactions but also suggest a direct Hh-mediated regulation of both intracellular signaling and cell adhesion through Ihog.
Roles of communication problems and communication strategies on resident-related job satisfaction

This study investigated the impact of dementia-related communication difficulties and communication strategies used by staff on resident-related indicators of role demand and role satisfaction. Formal/paid long-term care staff caregivers (N 1⁄4 109) of residents with dementia completed questionnaires on dementia-related communication difficulties, communication strategies, role demand (ie, residents make unreasonable demands), and role satisfaction (measured by relationship closeness and influence over residents). Three types of communication strategies were included: (a) effective repair strategies, (b) completing actions by oneself, and (c) tuning out or ignoring the resident. Analyses using structural equation modeling revealed that communication problems were positively linked with role demand. Repair strategies were positively linked with relationship closeness and influence over residents. Completing actions by oneself was positively linked to role demand and influence over residents, whereas tuning out was negatively linked with influence over residents. The findings underscore that effective caregiver communication skills are essential in enhancing staff–resident relationships.
On the Eects of Market Incumbency on Innovative Behaviour in the Pharmaceutical Industry

This paper evaluates the eects of market dominance on …rms'propensity to innovate and productivity in a panel of 77 pharmaceutical …rms for the period 1975-1991. While a higher market-share leads to a weaker propensity to innovate, incumbents …rms are found to be persistent innovators and notably, persistent sources of quality-patenting. Neverthe- less, incumbent …rms are subject to decreasing R&D productivity likely related to possible diseconomies of scale and organizational inertia.
Performance Assessment: How it Depends on Structural Economic Vulnerabilty and Human Capital. Implications for the Allocation of Aid

Developing country performance with respect to economic policies and institutional behaviour is a common criterion for the allocation of aid among recipient countries. This paper questions the manner in which performance is used in this regard, arguing that performance is too narrowly defined. A more appropriate definition is one that controls for the economic vulnerability and human capital of developing countries. Econometric analysis of cross-section and panel data is presented that supports this contention. The paper also contends that performance and exogenous economic shocks are likely to be pro-cyclical. This implied a double punishment when aid is allocated according to performance. Evidence of such punishment is also provided in this paper. The paper concludes by arguing that economic vulnerability and human capital variables should augment performance measures in aid allocation decision making.
Physicochemical Properties and Sensory Evaluation of Wheat-Purple Rice Biscuits Enriched with Green-Lipped Mussel Powder (Perna canaliculus) and Spices

Biscuits are one of the most consumed bakery products eaten by everyone. Purple rice contains much higher levels of antioxidants, vitamins, and minerals such as iron and zinc compared to wheat. The aim of this work was to produce a protein-rich biscuit made from purple rice flour and defatted green-lipped mussel powder (Perna canaliculus) (0–20%) blended with ginger and galangal spices at 4% for each spice. The objective was to produce an inexpensive, balanced, healthy snack product containing increased levels of protein and antioxidants from the mussel powder and to investigate the consumer preferences of these biscuits using the four different ethnic groups (Thai, Chinese, Caucasian, and Pacific Islanders) living in New Zealand. The addition of the mussel powder increased the crude protein content by 43% and the protein digestibility by 21% at the highest level of inclusion. The addition of mussel powder significantly ( ) increased the hardness of biscuits while making small increases in the browning index of the cooked biscuit. The phenolic contents and antioxidant activities (DPPH and ABTS) were significantly ( ) increased as additional amounts of mussel powder were incorporated into the biscuit mix, resulting in a reduction in the total starch contents. The addition of 10% mussel powder to the control biscuit mix was accepted by all the ethnic groups. Overall, the Pacific Islanders showed a higher appreciation for all the attributes tested.
Heavy-mineral derived provenance study of Quaternary sediments of the Mazovian Lowland, Central Poland

This study makes an attempt to characterise Quaternary sediments in terms of their heavy minerals (HM) composition. Authors focus on the Mazovian Lowland, Central Poland, where a number of clastic sediments of different age and origin overlap. Five sedimentary settings, covering the Saalian-Holocene (MIS 1-6) time frame, have been studied to reveal whether these sediments have single or multiple source areas and to decipher sediment transformations. In the glacial setting either garnetor amphibole-dominated sediments occur. This unequivocal mineral combination likely reflects a multi-sourcing resulting from multi-directional ice advance. The HM taken from fan-like forms and aeolian sediments are closely related; these sediments are largely multicyclic and likely derived from pre-existing recycling sediments. Similar mineral suite is also typical for long-lasting aeolian processes and is observed in dune sediments. Ultrastable components are less frequent in the coversand, which points at a shorter-lived aeolian process. Finally, the fluvial setting reveals multi-sourcing largely depending on local geological conditions.
Breaks and outliers when modelling the volatility of the U.S. stock market

ABSTRACT This study analyses volatility persistence of the U.S. stock market, after taking into account the role of breaks and outliers. By employing a wavelet-based algorithm, it identifies several outliers which are comfortably associated with major events such as the ‘Black Monday’ and the Asian crisis. There is also evidence of clustering of breaks and a substantial variation in the properties of the identified segments.
Bergen Earth system model (BCM-C): model description and regional climate-carbon cycle feedbacks assessment

Abstract. We developed a complex Earth system model by coupling terrestrial and oceanic carbon cycle components into the Bergen Climate Model. For this study, we have generated two model simulations (one with climate change inclusions and the other without) to study the large scale climate and carbon cycle variability as well as its feedback for the period 1850–2100. The simulations are performed based on historical and future IPCC CO2 emission scenarios. Globally, a pronounced positive climate-carbon cycle feedback is simulated by the terrestrial carbon cycle model, but smaller signals are shown by the oceanic counterpart. Over land, the regional climate-carbon cycle feedback is highlighted by increased soil respiration, which exceeds the enhanced production due to the atmospheric CO2 fertilization effect, in the equatorial and northern hemisphere mid-latitude regions. For the ocean, our analysis indicates that there are substantial temporal and spatial variations in climate impact on the air-sea CO2 fluxes. This implies feedback mechanisms act inhomogeneously in different ocean regions. In the North Atlantic subpolar gyre, the simulated future cooling of SST improves the CO2 gas solubility in seawater and, hence, reduces the strength of positive climate carbon cycle feedback in this region. In most ocean regions, the changes in the Revelle factor is dominated by changes in surface pCO2, and not by the warming of SST. Therefore, the solubility-associated positive feedback is more prominent than the buffer capacity feedback. In our climate change simulation, the retreat of Southern Ocean sea ice due to melting allows an additional ~20 Pg C uptake as compared to the simulation without climate change.
Stereoscopic Analysis and Depth Map Creation

This contribution is focused on the use of the stereoscopic image for the purpose of depth map creation. Further, methods for calibration of the camera(s) are discussed. A stereoscopic head was constructed for the purpose of creating a stereoscopic image. Two Basler acA1600-20uc industrial cameras with Computar M2514-MP2 lenses were used for constructing this head. Furthermore, the algorithm for obtaining the depth map is described. The programming language C# and EmguCV library were used for the implementation of the algorithm. The algorithm consists of 4 parts. The calibration of the camera(s) and image acquisition is solved as first. Calibration of the camera(s) is solved by detection of intersections on the chessboard. Further, methods for the purpose of obtaining the depth map are described. Finally the implemented algorithm is tested.
Geometry and velocity structure of HD 44179’s bipolar jet

In this paper we analyse a set of 33 optical spectra, which were acquired with the ARCES echelle spectrograph (R = 38,000) on the 3.5-m telescope at the Apache Point Observatory. We examine the H{\alpha} profile in each of these observations in order to determine the geometry and velocity structure of the previously discovered bipolar jet, which originates from the secondary star of HD 44179 located at the centre of the Red Rectangle nebula. Using a 3D geometric model we are able to determine the orbital coverage during which the jet occults the primary star. During the occultation, part of the H{\alpha} line profile appears in absorption. The velocity structure of the jet was determined by modelling the absorption line profile using the Sobolev approximation for each orbital phase during which we have observations. The results indicate the presence of a wide angle jet, likely responsible for observed biconical structure of the outer nebula. Furthermore, we were able to determine a likely velocity structure and rule out several others. We find that the jet is comprised of low-density, high-velocity, central region and a higher-density, lower-velocity, conical shell.
Response surface optimization of hot air-microwave combination drying of medicinal Indian Borage (Coleus aromaticus) leaves.

Experiments were conducted to optimize the drying parameters in hot air - microwave combination drying of borage (Coleus aromaticus) leaves which are medicinal in nature. Response surface methodology (RSM) was used to investigate the effect of microwave blanching power level (MWBPL), hot air drying temperature (HAT), hot air dr ying time (HAt) and microwave drying power level (MWDPL), in a two stage hot air-microwave combined drying of borage leaves. Optimization of process parameters was performed to result maximum total phenolics and antioxidant values with minimum total drying time. A central composite rotatable design was applied and the results were analyzed using mult i- ple response technique. The proposed models for all the responses were statistic ally verified to be adequate and satisfa c- tory. The regression coefficients of second order model and the probability of factors infl uencing the response at linear, quadratic and interactive level has been analyzed thoroughly. The optimum process conditions were determined to be 730W, 65°C, 30min and 650W for microwave blanching power level (MWBPL), hot air drying temperature (HAT), hot air drying time (Hat), microwave drying power level (MWDPL) respectively with an output of 1050.42mg/100g,372.23M/g and 33 . 67min for total phenolics (TP), antioxidant (AO) and total drying (TDT) respe c- tively. Superimposed contour plots could give rise to feasible zones for various combinations of opera ting parameters in order to have a better flexibility in the selection of o perating range.
Nonlinear effects of oil prices on inflation, growth, budget deficit, and unemployment

Dec. 31, 2016 In oil-exporting countries such as members of the OPEC, fluctuations in oil prices exert a significant impact on the domestic economy. Currently, a sharp reduction in oil prices results in several adverse effects; however, for such a crude-oil exporter that is also an importer of petroleum products as Vietnam, does a rise or drop in oil prices is beneficial to its development? This paper attempts to determine the oil price threshold while analyzing oil price effects on several macro factors, such as inflation, GDP growth, budget deficit, and unemployment rate over the 2000–2015 period. Using TVAR model, we detect an oil price threshold of USD27.6/barrel. Moreover, an increase in the price of oil, which exceeds this threshold, will cause a rise in inflation, budget deficit, and unemployment rate. Still, there is no significant evidence of the impact of oil prices on GDP growth.
Utilization of kelp-derived carbon sources by kelp surface-associated bacteria

The surfaces of kelp are covered with bacteria that may utilize kelp-produced carbon and thereby contribute significantly to the carbon flux in kelp forest ecosystems. There is scant knowledge about the identity of these bacteria and about which kelp-derived carbon sources they utilize. An enrichment approach, using kelp constituent carbon sources for bacterial cultivation, was used to identify bacterial populations associated with the kelp Laminaria hyperborea that degrade kelp components. In order to assess whether the cultured bacteria are significant under natural con- ditions, partial 16 rRNA gene sequences from the cultured bacteria were compared to sequences obtained from the indigenous bacterial communities inhabiting natural kelp surface biofilms. The results identify different members of the Roseobacter clade of Alphaproteobacteria in addition to members of Gammaproteobacteria that are involved in kelp constituent degradation. These bacteria are observed sporadically on natural kelp surfaces and may represent opportunistic bacteria impor- tant in degradation of dead kelp material. Many of the cultured bacteria appear to be generalists that are able to utilize different kelp carbon sources. This study is the first to link culturable kelp- associated bacteria with their occurrence and possible roles in the natural environment.
Preparation of II-VI group semiconductor nanowire arrays by dc electrochemical deposition in porous aluminum oxide templates

Abstract II-VI group compound semiconductors such as CdS, CdSe, and CdTe nanowire arrays have been prepared by direct current electrodeposition in porous anodic aluminum oxide template from nonaqueous electrolyte. SEM and TEM results show that these nanowires have a highly anisotropic structure of aligned nanowires with diameters of 15-200 nm, which are consistent with the diameters of the templates used. Electron diffraction and HREM investigations demonstrate that the crystalline structures of these nanowires are uniform hexagonal single crystal. This approach can be used to fabricate single crystal nanowire arrays of a wide range of semiconductors and other materials.

Novel Technique for Profiling of Aerosol, Ozone and Water Vapor during Winter Using Mobile Radiometers over a Hilltop Station

Following a novel approach, the vertical distributions of columnar aerosol optical depth (AOD), precipitable water content (PWC) and ozone (TCO) have been determined using compact, multi-filter, solar radiometers during winter period of 2002-2003. These profiles were obtained by making measurements at different altitudes while ascending to/descending from a rural site, elevated up to an altitude of about 1450 m above mean sea level (AMSL). Besides the wavelength dependency, the profiles depict significant layer structures which are explained on the basis of concurrent atmospheric stability parameters. The aerosol size distributions which were obtained from the inversion of spectral dependence of AOD at different altitudes show a mixture of power-law, mono- and bi-model distributions indicating the influence of aerosols originating from both anthropogenic and natural sources. The present results, representing a rural high-altitude station, are compared with those reported over a few selected similar high-altitude stations in North India, and also observed at a nearby urban station (Pune) in Central India to infer modulation of terrain-induced meteorological parameters on aerosol source strength. The importance of the experimental approach and profiles of AOD and pre-cursor gases over areas with scarce alternative measurements, networks with sporadic presence of ground sites and limited number of satellite retrievals is highlighted.
Transparency in Politically Connected Firms: Evidence from Private Sector Firms in China

Using a sample of listed Chinese private sector firms, we show that politically connected firms are less likely to engage high-quality (big) auditors, less timely in recognizing losses, and exhibit higher discretionary accruals than similar non-connected firms. Together, these results suggest that politically connected private sector firms in China exhibit lower transparency than non-connected firms. We control for reverse causality by showing that firms which newly acquire political connections are more likely than nonconnected firms to switch to small auditors. The results are also robust after controlling for endogeneity in a two-stage model. The likelihood of engaging big auditors is reduced further for politically connected firms in regions with weaker market institutions and in periods before enforcement action for corporate fraud. We also find that the post-listing performance of politically connected firms is superior to that of non-connected firms, resulting in a net benefit for minority shareholders. Out of all the potential benefits arising from political connections, our findings are consistent with rent-seeking being the dominant one.
