Relationship between glacial isostatic adjustment and gravity perturbations observed by GRACE

The Gravity Recovery and Climate Experiment space gravity mission provides one of the principal means of estimating present‐day mass loss occurring in polar regions. Extraction of the mass loss signal from the observed gravity changes is complicated by the need to first remove the signal of ongoing glacial isostatic adjustment (GIA) since the Last Glacial Maximum. This can be problematic in regions such as Antarctica where the GIA models are poorly constrained by observation and their accuracy is not well known. We present a new methodology that permits the GIA component to be represented mathematically by a simple, linear expression of the ratio of viscoelastic Love numbers that is valid for a broad range of Earth and ice‐load models. The expression is shown to reproduce rigorous computations of surface uplift rates to within 0.3 mm/yr, thus providing a means of inverting simultaneously for present‐day mass loss and ongoing GIA with all the accuracy of a fully detailed forward model.
EXPERIMENTAL STUDY OF THERMAL EFFECTS IN COOLING OF CIRCULAR CYLINDER IN LOCK-ON CONDITIONS

The paper presents a simple method for determining the phenomenon of unsteady thermal effects in cooling a circular cylinder. The research has been undertaken in order to explain the thermoaerodynamic processes, which are characterized by the turbulent structure of the flow around a stationary rigid heated cylinder cooled by the oscillating flow. The forced convection of heat occurs in the presence of not only random velocity fluctuation but also in the conditions of periodical forms of motion caused mainly by the process of vortex going down and externally formed oscillations of the inflow. The Nusselt number was evaluated at various frequencies of disturbances of the inlet velocity field, especially in lock-on conditions, on the surface of the circular cylinder versus angular location Θ = 0-180°. The subject of the study focuses on the analysis of current state of the problem and development of the method to measure and calculate basic values that characterize unsteady processes of thermal effects on the circular cylinder surface and indication of the directions of further work.
Nitrogen transformations along a shallow subterranean estuary

Abstract. The transformations of chemical constituents in subterranean estuaries (STEs) control the delivery of nutrient loads from coastal aquifers to the ocean. It is important to determine the processes and sources that alter nutrient concentrations at a local scale in order to estimate accurate regional and global nutrient fluxes via submarine groundwater discharge (SGD), particularly in boreal environments, where data are still very scarce. Here, the biogeochemical transformations of nitrogen (N) species were examined within the STE of a boreal microtidal sandy beach located in the Magdalen Islands (Quebec, Canada). This study revealed the vertical and horizontal distribution of nitrate (NO3−), nitrite (NO2−), ammonia (NH4+), dissolved organic nitrogen (DON) and total dissolved nitrogen (TDN) measured in beach groundwater during four spring seasons (June 2011, 2012, 2013 and 2015) when aquifer recharge was maximal after snowmelt. Inland groundwater supplied high concentrations of NOx and DON to the STE, whereas inputs from seawater infiltration were very limited. Non-conservative behaviour was observed along the groundwater flow path, leading to low NOx and high NH4+ concentrations in the discharge zone. The long transit time of groundwater within the beach (∼ 166 days), coupled with oxygen-depleted conditions and high carbon concentrations, created a favourable environment for N transformations such as heterotrophic and autotrophic denitrification and ammonium production. Biogeochemical pathways led to a shift in nitrogen species along the flow path from NOx-rich to NOx-poor groundwater. An estimate of SGD fluxes of N was determined to account for biogeochemical transformations within the STE based on a N-species inventory and Darcy's flow. Fresh inland groundwater delivered 37 mol NOx yr−1 per metre of shoreline and 63 mol DON m−1 yr−1 to the STE, and NH4+ input was negligible. Near the discharge zone, the potential export of N species was estimated around 140, 1.5 and 33 mol yr−1 per metre of shoreline for NH4+, NOx and DON respectively. In contrast to the fresh inland groundwater, the N load of beach groundwater near the discharge zone was dominated by NH4+ and DON. Our study shows the importance of tidal sands in the biogeochemical transformation of the terrestrial N pool. This local export of bioavailable N probably supports benthic production and higher trophic levels leading to its rapid transformation in surface sediments and coastal waters.
Anti-oxidant and anti-microbial study of Adiantum capillus veneris and Pteris quadriureta L

Adiantum capillus veneris (ACV) and Pteris quadriureta (PQ), two common ferns belonging to Pteridophyta family, has been used in traditional Ayurvedic and Unani medicine against numerous human ailments since ancient times. This study was designed to analyse the presence of various phytochemicals in the ACV and PQ leaves and their pharmacological activities. The methanol extract of ACV and PQ leaves was screened for the presence of various primary and secondary metabolites such as proteins, lipids, phenols, flavonoids, alkaloids, saponins, and tannins. Anti-oxidant, anti-bacterial, and anti-fungal activities were also analysed for methanolic extracts of ACV and PQ leaves using various methods. Various metabolites such alkaloids, phenols, flavonoids, saponins and tannins in the ACV and PQ leaves were found. Phenols and flavonoids were present in high concentration when compared with other metabolites. The results also showed that methanolic extracts of ACV and PQ leaves have anti-oxidant, anti-haemolytic, anti-bacterial, and anti-fungal activities. The pharmacological activities such as anti-oxidant, anti-haemolytic, anti-bacterial, and anti-fungal activities of ACV and PQ leaves might be due to the presence of phenols and flavonoids. Key words: Adiantum capillus veneris, Pteris quadriureta, anti-bacterial, anti-fungal, anti-oxidant, phytochemicals.
THE IMPACT OF DIVIDEND POLICY ON THE SHARE PRICE VOLATILITY: Malaysian Construction and Material Companies.

This study presents the results on the impact of dividend policy on the share price volatility of the Malaysian listed construction and material companies using the least square regression method after controlling for debt, firm size, investment growth and earnings’ volatility. The study found only 43.43 percent of the changes in the share prices are explained by dividend yield (DY), dividend payout ratio(DPR), and investment growth(Growth), size of the firm )FZ), leverage (Lev) and earnings volatility (EV). These companies recorded 94.41 percent share price volatility during 2005 until 2010. Dividend payout ratio significantly influences the changes in share price. The greater the size of the company, the more significant impacts the volatility of share price would be. Dividend yield, investment growth and earnings volatility insignificantly influence the changes in the company’s share prices. Leverage is negatively influence the movement of the share price.
The Value Relevance of International Financial Reporting Standards: Evidence for an Emergent Capital Market

The paper explores the benefits of global financial reporting models for developing countries, discussing the case of Romania, which, at the recommendations of the World Bank and the International Monetary Fund, exceeded the minimum requirements of the European Union, by imposing the full adoption of the International Financial Reporting Standards (IFRS) in individual financial statements of listed companies. Using regression analysis and decomposition techniques, the paper explores the evolution in value relevance of financial variables based on pre-(2009-2012) and post-(2014-2016) adoption samples, showing that after IFRS adoption financial information becomes significantly more relevant for equity valuations. We also provide empirical evidence showing that the degree of relevance for stock valuation, as well as the IFRS impact varies across types of firms. Overall, our findings tend to indicate the success of the financial reporting reform, which could be relevant for other jurisdictions facing similar decisions.
EPIDEMIOLOGY OF COLLE TOTRICHUM A CUTA TUM, CAUSE OF ANTHRACNOSE ON HIGHBUSH BLUEBERRY, IN BRITISH COLUMBIA

Blueberry anthracnose reduces yield and post-harvest quality of blueberries in British Columbia. Isolates recovered from diseased fruit during 2002-2004 were identified as Colletotrichum acutatum using colony morphology, growth rate, and PCR. Leaf-wetness and temperature data indicated that plants exposed to prevailing environmental field conditions and natural inoculum in 2001-2003 required 10 hr of leaf wetness at 1 1•‹C for successful fruit infection. Three peaks of infection occurred; at blossoming, mature green berry stage, and ripening. Artificially inoculated plants in 2004 were found to be susceptible throughout the season, indicating that inoculum availability and weather conditions primarily affected disease. The pathogen overwintered mostly in flower buds and infection in May-July of the preceding season resulted in the greatest inoculum recovery. Two fungal biocontrol agents, Gliocladium catenulatum and Trichoderma harzianum, reduced anthracnose by up to 45% when applied thrice in 20032004. Infection requirements and related epidemiological data support effective management of this disease.
Distribution and abundance of cultured scallop Patinopecten yessoensis in extensive sea beds as assessed by underwater camera

A simple and precise system for population estimation of epi-megabenthos using an underwater photographic camera is proposed. A standard 35 mm film camera with motor wind mounted in an underwater case is attached on a stainless steel frame to photograph 1 m2 of sea bed. The camera is triggered by a rigid foot switch set off on contact with the sea bed; thus, only vertical lowering is needed in operation. Two-stage samphng was employed to estimate the extensively cultured Japanese scallop Patinopecten yessoensis; estimated densit~es were highly accurate and relative standard errors were within only 0.05 of the means. The estimated amount of harvest approximated closely the actual harvest. Precise density changes in a cohort, from seed release time to harvest, could be followed, providing essential information for fishery management of scallops. The distribution pattern of the population was analyzed. Contagious distribution patterns of the scallops were detected on a large scale, and they showed large areas of patchiness, but random distribution of individual scallops within the patches was observed on a small scale. Contagiousness decreased with age. Factors affecting the distribution pattern on large and small scales are discussed in relation to substrate types, current flow with subsequent downstream dispersal during swimmiig movements, and possible food depletion.

Idiosyncratic Risk and Asset Pricing Anomalies

The aim of this paper is two-fold. Firstly, we follow the theoretical model of Merton (1987) and provide a new perspective of study about the role of idiosyncratic risk in the asset pricing process analyzing whether the idiosyncratic risk premium depends on the idiosyncratic risk level of an asset as well as the variations in the market-wide measure of idiosyncratic risk. Secondly, we evaluate the informative content of this kind of risk in asset pricing analyzing whether it can help explain those anomalies related to the specific characteristics of an asset such as size, value, liquidity and past returns. Our findings contribute to provide an answer for the main unsolved questions about the idiosyncratic risk puzzle: whether there exists a premium associated to this kind of risk, the sign of this risk premium and its informative content.
Searching for transits in the Wide Field Camera Transit Survey with difference-imaging light curves

The Wide Field Camera Transit Survey is a pioneer program aiming at for searching extra-solar planets in the near-infrared. The images from the survey are processed by a data reduction pipeline, which uses aperture photometry to construct the light curves. We produce an alternative set of light curves using the difference-imaging method for the most complete field in the survey and carry out a quantitative comparison between the photometric precision achieved with both methods. The results show that difference-photometry light curves present an important improvement for stars with J {gt} 16. We report an implementation on the box-fitting transit detection algorithm, which performs a trapezoid-fit to the folded light curve, providing more accurate results than the box-fitting model. We describe and optimize a set of selection criteria to search for transit candidates, including the V-shape parameter calculated by our detection algorithm. The optimized selection criteria are applied to the aperture photometry and difference-imaging light curves, resulting in the automatic detection of the best 200 transit candidates from a sample of ~{}475 000 sources. We carry out a detailed analysis in the 18 best detections and classify them as transiting planet and eclipsing binary candidates. We present one planet candidate orbiting a late G-type star. No planet candidate around M-stars has been found, confirming the null detection hypothesis and upper limits on the occurrence rate of short-period giant planets around M-dwarfs presented in a prior study. We extend the search for transiting planets to stars with J {le} 18, which enables us to set a stricter upper limit of 1.1%. Furthermore, we present the detection of five faint extremely-short period eclipsing binaries and three M-dwarf/M-dwarf binary candidates. The detections demonstrate the benefits of using the difference-imaging light curves, especially when going to fainter magnitudes.
Early time optical spectroscopy of supernova SN 1998S

We present medium-resolution optical spectra of the type II supernova SN 1998S obtained during the pre-maximum, maximum and early decline phases. The early decline spectra show complex Balmer line profiles: a narrow P-Cygni emission feature superimposed on a broad emission. The narrow emission has a redshift similar to that of the host galaxy, indicating its origin from a pre-supernova circumstellar material. The H α luminosity of the broad component implies a shell mass of ∼ 0.1 $M_\odot$ for the supernova ejecta, while the luminosity of the narrow component implies a mass loss rate of $10^{-4} M_\odot$ yr -1 for the precursor. The photospheric temperature of the supernova shell decreased from a value of $18 400\pm 2900$ K on day 17 to a value of $7500\pm 1200$ K on day 44. The observations indicate SN 1998S belongs to type IIn supernovae where the supernova ejecta dynamically interact with a pre-supernova circumstellar material.

A single drought event of 100-year recurrence enhances subsequent carbon uptake and changes carbon allocation in experimental grassland communities §

Evidence suggests that the expected increase in frequency and magnitude of extreme weather events during climate change will alter plant productivity. Therefore, extreme weather events might also be capable of changing C sequestration and allocation. Here, experimental grassland communities of two species compositions, differing in their diversity, were exposed either to a simulated single drought or to a heavy-rainfall event. The magnitude of these manipulations imitated the local 100-year weather extreme according to extreme-value statistics. Effects on Net Ecosystem CO2 Exchange (NEE in lmol m–2 s–1) as well as aboveground biomass production and leaf-area index (LAI) were recorded from prior to the manipulations until two months after the manipulations ended. Initial light utilization efficiency and maximum NEE increased after the drought. No change in the respiration was detected and maximum uptake capacity (GPPmax) was 15% higher for the drought-manipulated plots compared to controls, which indicates an enhanced CO2 uptake into the systems. The level of diversity was also found to alter the lightresponse curves, increasing respiration and maximum NEE to a higher degree than drought in the more diverse compared to the less diverse community. This resulted in an increase of GPPmax by 55%. No significant interactions between species composition and weather manipulations were detected. Interestingly, aboveground biomass production was not significantly affected by weather manipulations, even though LAI increased due to drought. This increase was caused by a decrease in the ratio between reproductive and vegetative growth. The heavyrainfall manipulation resulted in no significant effects. Our data suggest that C sequestration can be enhanced by a single weather event. However the importance, long-term duration, and thresholds or turning points of such effects need to be investigated further as intensification of weather extremes is currently emerging as one of the most important facets of climate change.
Antioxidant and selenium status of laying hens fed with diets supplemented with selenite or Se-yeast *

The experiment was designed to investigate the effects of feed supplementation with selenite or selenized yeast on parameters of antioxidant and selenium status of laying hens. Hens of laying breed Shaver Starcross 288 were randomly divided at the day of hatching into 4 groups and fed for 9 months on diets which differed only in amounts or forms of selenium supplemented. Group 1 was fed the basal diet (BD) with native Se content 0.1 mg . kg -1 DM. Groups 2 and 3 were fed the BD diets supplemented with equivalent Se dose 0.4 mg . kg -1 DM of either sodium selenite or Se-yeast, respectively. The diet for group 4 was supplemented with Se-yeast at Se dose 0.9 mg . kg -1 DM. The activities of glutathione peroxidase (GPx) in blood and tissues of liver, kidney and duodenal mucosa were significantly increased by Se supplementation, but no differences due to form or dose of Se were observed. Both Se sources resulted in significant reduction of superoxide dismutase (SOD) activity in erythrocytes. Malondialdehyde (MDA) content in kidney tissue was reduced by both Se sources, but its production in liver tissue was inhibited by Se-yeast only. Selenium supplementation did not influence the levels of MDA and -SH groups in plasma. Altrough both Se significantly raised Se concentrations in blood and tissues of liver, kidney, spleen, hearth and duodenal mucosa, significant Se deposition into muscles appeared in hens given Se-yeast only. The presented results suggest that Se-yeast is more effective in maintenance of antioxidant and selenium status of laying hens than selenite.
Wealth Effects or Economic Barometer: Why Do House Prices Matter for Psychological Health?

This paper investigates whether house prices are linked to mental health outcomes, and whether this association arises through wealth effects or whether third factors such as area amenities or economic conditions drive both house prices and psychological health. These alternative explanations have contrasting implications for the effect of house prices on the well-being of homeowners and non-homeowners, which are exploited in the empirical analysis. I document a positive association between house prices and the mental health of homeowners and non-homeowners, which is not consistent with wealth effects. Further analysis indicates that house prices matter via a role as an economic barometer.

Effect of banana peel cellulose as a dietary fiber supplement on baking and sensory qualities of butter cake

Banana peels are a waste product of the banana industry that have caused an environmental problem. Conversion of banana peels to a food ingredient might be an alternative way of value-adding to this waste. This study aimed to extract cellulose from banana peels and use it as an ingredient in butter cake to increase dietary fiber content and to improve cake quality. The selection and optimization of extraction conditions of cellulose from banana peels employed chemical extractions. Banana peel cellulose (BPC) was added to butter cake at 3 levels; 1.5, 3.0 and 4.5% w/w of flour compared with 3.0% commercial cellulose (CC) and the control (no cellulose added). The sensory, chemical, physical and microbiological properties of the butter cakes were then determined. The odor, tenderness and moistness acceptance scores of the butter cake by 50 panelists ranged from “like moderately” to “like very much”, indicating that addition of BPC improved the sensory quality of the cake. The butter cake with added CC and BPC had significantly higher (pd”0.05) moisture and fiber contents than those of the control. Microorganism levels found in the butter cake conformed to the butter cake standard (OTOP standard product of Thailand 459/2549). The optimum concentration of added BPC was 1.5%. Thus, the addition of BPC extracted from banana peels to butter cake increased the fiber content and improve the cake quality.
