Formation, Thermal Stability and Mechanical Properties of Cu-Zr-Al Bulk Glassy Alloys

New Cu-based bulk glassy alloys with large supercooled liquid region and high mechanical strength were found to be formed in Cu-Zr-Al ternary system. The large supercooled liquid region exceeding 70 K was obtained in the composition range of 40 at%Zr at 2.5 at%Al, 37.5%Zr to 47.5%Zr at 5%Al and 42.5%Zr at 7.5%Al. The largest ΔT x was 74 K for Cu 55 Zr 40 Al 5 and Cu 50 Zr 42.5 Al 7.5 alloys and the highest T g /T l was 0.62 for the former alloy. The alloys with large ΔT x values above 70 K were formed into a bulk glassy rod form with diameters up to 3 mm by copper mold casting and the glassy alloy rods exhibit high compressive strength of 1885 to 2210 MPa and Young's modulus of 102 to 115 GPa combined with elastic elongation of 1.60 to 1.95% and plastic elongation of 0 to 0.4%. The addition of 2.5 to 7.5°%Al to Cu-Zr alloys was very effective for the increase in glass-forming ability as well as the stabilization of supercooled liquid. The effectiveness can be interpreted on the basis of the concept of the formation of the unique glassy structure in special multi-component alloys with the three empirical component rules.

Effect of Refeeding on Lipid Metabolism in Kamphaengsaen Beef Heifers

Five Kamphaengsaen (Charolais Crossbred) beef heifers were used to study lipid utilization during a 30-day controlled-feed realimentation period. Dry matter intake was adjusted according to individual metabolic body weight to provide the same energy intake as in the full feeding period. At the end of refeeding period the heifers showed better feed conversion ratio. Back fat thickness increased and returned to the same level as before restriction (0.284 vs. 0.262 cm.). The loin eye area exhibited slight accretion (less than 1% of the loin eye area at the onset of realimentation). Adipose tissue lipolytic rate remained elevated and the heifers also exhibited high rate of lipoprotein export as in the previous restriction period. Plasma albumin concentration was higher than the base-line concentration. NEFA concentration declined and tended to be less than the base line concentration level (86vs.127μ mol/l). Because the high lipolytic rate occurred at this period, less circulating NEFA concentration was suggested for the high NEFA uptake by the peripheral tissue. BHBA and glucose concentrations were rebounded toward the base-line concentrations. PUN concentration markedly declined with the level lower P<0.05 than the base-line concentration (9.2 vs.10.8 mg/dl). This might result from the decreasing rate of catabolism of labile protein reserved. In conclusion, it was found that during repletion, the heifers utilized fat as the essential source of fuel and decreased proteolysis in the body.
The learning organisation 2.0? A participative and exploratory case study on corporate blogging

The phenomenons called blogging and learning organisations are both contemporary and research is inconclusive (e.g. Easterby-Smith et al., 2000 and Wattal et al., 2009). This study aims to merge the two by means of a participative and exploratory case study on corporate blogging. By use of qualitative interviews and a data analysis focusing on concentrated meanings and thematic categorisation, the purpose is to explore how corporate blogging could be related to developing learning organisations – for which the scientific base mainly consists of Senge's (1990) five disciplines regarding learning organisation; personal mastery, mental models, shared vision, team learning, and systems thinking; and various prior research on blogging (e.g. Gilbert et al., 2009 and Adamic & Glance, 2004). This study aims towards deepening the understanding of the above relationship and to generate new ideas for future research. The case study takes place at a department working with electronic communication, part of a global company with over 20 000 employees, that use an internal pilot blog for a period of one month. There are 21 full-time employed persons and about five consultants working in this specific department. Findings reveal that some aspects of creating learning organisations seem to have different kinds of relations to corporate blogging – taking either the role of an enabling process for blogs or for the development of a learning organisation – following which a general framework is used to depict how these different aspects may operate and suggestions on future research are presented.
The star formation and chemical evolution history of the Fornax dwarf spheroidal galaxy

We have combined deep photometry in the B, V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest main sequence turn-offs, with spectroscopic metallicity distributions of red giant branch stars. This allows us to obtain the most detailed and complete star formation history to date, as well as an accurate timescale for chemical enrichment. The star formation history shows that Sculptor is dominated by old (>10 Gyr), metal-poor stars, but that younger, more metal-rich populations are also present. Using star formation histories determined at different radii from the centre we show that Sculptor formed stars with an increasing central concentration with time. The old, metal-poor populations are present at all radii, while more metal-rich, younger stars are more centrally concentrated. We find that within an elliptical radius of 1 degree, or 1.5 kpc from the centre, a total mass in stars of 7.8 × 10^6 M
Comparative Effects of Different Fertilizer Sources on the Growth and Nutrient Content of Moringa (Moringa oleifera) Seedling in a Greenhouse Trial

A greenhouse experiment was conducted to investigate the effects of NPK, poultry manure, and organomineral fertilizer on the growth and nutrient concentration of Moringa oleifera leaves. The experimental design was completely randomized design (CRD) with four treatments replicated three times. Data collected were analysed using descriptive statistics and ANOVA at . Growth parameters measured include number of leaves per plant, plant height (cm), and stem girth (mm). The application of poultry manure increased the height, number of leaves, and stem girth of moringa compared to the application of NPK and organomineral fertilizer while the control had the least growth. Poultry manure, NPK, and organomineral fertilizer were 66%, 62%, and 39% higher in number of leaves than the control at eight weeks after planting. The application of poultry manure significantly increased the nutrient content of moringa leaves compared to other sources of fertilizer applied. The results shows that the application of poultry manure significantly improved the growth and nutrient content of moringa; however, further field trial is suggested.
pproach to spot overlapping problem in 2 D-PAGE evealed clinical and functional significance of RKIP nd MnSOD in renal cell carcinoma

Previously, we identified protein spots with differential intensity between normal and tumor tissues of renal cell carcinoma (RCC) using 2D-DIGE. Here, we further examined two proteins, raf-1 kinase inhibitory protein (RKIP) and manganese superoxide dismutase (MnSOD), identified in one protein spot. Western blotting demonstrated that RKIP and MnSOD exhibited opposite expression patterns in normal and tumor tissues. Immunohistochemisry showed that MnSOD level significantly correlated with shorter progression-free survival. Gene-silencing assay demonstrated that RKIP and MnSOD had suppressive and promotive effects on tumor cell proliferation and invasion, respectively. Our findings reveal biological and clinical significance of RKIP and MnSOD in RCC.
Practise makes perfect: developing critical thinking and writing skills in undergraduate science students

Successful undergraduate students are required to demonstrate critical thinking and writing skills in their final year dissertation, but the early years of some science degrees may not fully prepare them for this challenge. This study investigated the value of earlier engagement with scientific literacy skills by assessing the impact of rehersing critical thinking and extended writing skills earlier in the degree programme. This paper reports a small-scale study of a single cohort of students on BSc (Hons.) Biomedical Sciences degree schemes at a research-intensive university and describes quantitative analysis of students' performance in two research-driven writing tasks at different stages of the degree: a literature review in Year 2 and a research dissertation in the final year. The results of this study support the comcept that earlier exposure to extended writing tasks requiring scientific literacy skills is beneficial to students whose final year project has similar literature-based format; the experience of completing the literature review appears particularly valuable in improving the academic performance of weaker students.
Probing for Proof, Plausibility, Principle and Possibility: A New Approach to Assessing Evidence in a Systematic Evidence Review

type="main" xml:id="dpr12145-abs-0001"> This article proposes a new approach to assessing evidence during a systematic evidence review aiming to inform international development policy. Drawing lessons from a number of social science systematic evidence reviews, the article identifies how the method's limiting perspective on evidence (including the exclusive focus on ‘gold standard’ empirical information) has serious disadvantages for the usability of evidence reviews for policy. This article aims to provide an alternative framework that allows for a less exclusionary, yet policy-practical, way of assessing evidence. We propose four perspectives on evidence, appropriate for different stages in the policy process: principle when setting or prioritising broad policy goals, plausibility when assessing specific future policies, proof when evaluating past policies and possibility when striving for innovation and allowing exchange of ideas.
1 2 D ec 2 01 2 On Lagrangians of r-uniform Hypergraphs

A remarkable connection between the order of a maximum clique and the Lagrangian of a graph was established by Motzkin and Straus in [7]. This connection and its extensions were successfully employed in optimization to provide heuristics for the maximum clique number in graphs. It has been also applied in spectral graph theory. Estimating the Lagrangians of hypergraphs has been successfully applied in the course of studying the Turán densities of several hypergraphs as well. It is useful in practice if Motzkin-Straus type results hold for hypergraphs. However, the obvious generalization of Motzkin and Straus’ result to hypergraphs is false. We attempt to explore the relationship between the Lagrangian of a hypergraph and the order of its maximum cliques for hypergraphs when the number of edges is in certain range. In this paper, we give some Motzkin-Straus type results for r-uniform hypergraphs. These results generalize and refine a result of Talbot in [19] and a result in [11]. keywords: Cliques of Hypergraphs; Lagrangians of Hypergraphs; Optimization.
Late Miocene large mammals from Ivand (Northwestern Iran)

ABSTRACT Large mammalian fossil fauna of the Ivand locality in northwestern Iran is reported for the first time. This new locality is situated north of the city of Tabriz in the geographical proximity of the famous Maragheh fossil sites. A large hipparion, represented by an almost complete skull and mandibles, is recorded from this locality. The skull, most likely of Hipparion giganteum-Hipparion brachypus lineage, represents significant evidence of the presence of large hipparionine horses in northwestern Iran in the Late Miocene. A small number of horn-cores attributed to Oioceros atropatenes Rodler & Weithofer, 1890 and Gazella sp. , in addition to some indeterminate dentition, represent the bovid material in the Ivand fossil assemblage. Postcranial evidence also points to the presence of Deinotherium giganteum Kaup, 1829 and Rhinocerotinae indet. , while other material adds carnivorans, giraffes and large porcupine rodents to the list of the fauna. Based on the occurrence of these taxa, the Ivand locality can be correlated with the Middle and Upper Maragheh biostratigraphical intervals, thus demonstrating a middle Turolian age (c. 8–7 Ma).
Datafication and empowerment: How the open data movement re-articulates notions of democracy, participation, and journalism

This article shows how activists in the open data movement re-articulate notions of democracy, participation, and journalism by applying practices and values from open source culture to the creation and use of data. Focusing on the Open Knowledge Foundation Germany and drawing from a combination of interviews and content analysis, it argues that this process leads activists to develop new rationalities around datafication that can support the agency of datafied publics. Three modulations of open source are identified: First, by regarding data as a prerequisite for generating knowledge, activists transform the sharing of source code to include the sharing of raw data. Sharing raw data should break the interpretative monopoly of governments and would allow people to make their own interpretation of data about public issues. Second, activists connect this idea to an open and flexible form of representative democracy by applying the open source model of participation to political participation. Third, activists acknowledge that intermediaries are necessary to make raw data accessible to the public. This leads them to an interest in transforming journalism to become an intermediary in this sense. At the same time, they try to act as intermediaries themselves and develop civic technologies to put their ideas into practice. The article concludes with suggesting that the practices and ideas of open data activists are relevant because they illustrate the connection between datafication and open source culture and help to understand how datafication might support the agency of publics and actors outside big government and big business.
Generalized Hill-stability criteria for hierarchical three-body systems at arbitrary inclinations

A fundamental aspect of the three-body problem is its stability. Most stability studies have focused on the co-planar three-body problem, deriving analytic criteria for the dynamical stability of such pro/retrograde systems. Numerical studies of inclined systems phenomenologically mapped their stability regions, but neither complement it by theoretical framework, nor provided satisfactory fit for their dependence on mutual inclinations. Here we present a novel approach to study the stability of hierarchical three-body systems at arbitrary inclinations, which accounts not only for the instantaneous stability of such systems, but also for the secular stability and evolution through Lidov-Kozai cycles and evection. We generalize the Hill-stability criteria to arbitrarily inclined triple systems, explain the existence of quasi-stable regimes and characterize the inclination dependence of their stability. We complement the analytic treatment with an extensive numerical study, to test our analytic results. We find excellent correspondence up to high inclinations $(\sim120^{\circ}$), beyond which the agreement is marginal. At such high inclinations the stability radius is larger, the ratio between the outer and inner periods becomes comparable, and our secular averaging approach is no longer strictly valid. We therefore combine our analytic results with polynomial fits to the numerical results to obtain a generalized stability formula for triple systems at arbitrary inclinations. Besides providing a generalized secular-based physical explanation for the stability of non co-planar systems, our results have direct implications for any triple systems, and in particular binary planets and moon/satellite systems; we briefly discuss the latter as a test case for our models.
Ad hoc procedure for optimising agreement between observational records

Observational studies in the field of sport are complicated by the added difficulty of having to analyse multiple, complex events or behaviours that may last just a fraction of a second. In this study, we analyse three aspects related to the reliability of data collected in such a study. The first aim was to analyse and compare the reliability of data sets assessed quantitatively (calculation of kappa statistic) and qualitatively (consensus agreement method). The second aim was to describe how, by ensuring the alignment of events, we calculated the kappa statistic for the order parameter using SDIS-GSEQ software (version 5.1) for data sets containing different numbers of sequences. The third objective was to describe a new consultative procedure designed to remove the confusion generated by discordant data sets and improve the reliability of the data. The procedure is called “consultative” because it involves the participation of a new observer who is responsible for consulting the existing observations and deciding on the definitive result.
Goldilocks and the Three Electricity Prices: Are Irish Prices “Just Right”?*. ESRI WP372. January 2011

In this paper we analyse the 2008 electricity price in the Irish All-Island Market. We test whether this price is ‘efficient’ by comparing it to the electricity price in Great Britain. This analysis suggests that around €16 per MWh of the difference in wholesale prices between Ireland and Britain is due to differences in generating technology. The new wholesale electricity market for the island of Ireland appears to be working well – it is producing a wholesale price that approximates the long run marginal cost that would apply in a large liquid competitive market. In the British market the wholesale price appears to be below the long run marginal cost of producing electricity. Retail margins in Great Britain are high, especially for households. Only some of this margin compensates vertically integrated utilities for the low wholesale price. In the Republic of Ireland the retail margin was probably also higher than it should have been.
Global Financial Crisis and Stock Market Integration between Northeast Asia and Europe

This study examines the effect of financial crisis on the level of stock market integration. In particular, we investigated the dynamic movements of two regional stock markets, Northeast Asia and Europe during the period between January 1st, 2000 and December 31st, 2012, with particular attention placed on the global financial crisis (GFC). For this purpose, the paper employs various approaches including DCC-MGARCH, Risk Decomposition, GVAR, and CCOR models to ensure the robustness of empirical findings. The findings of this study are as follows. First, the Northeast Asian stock market remains independent from the European and global stock market movements during the sample period. Second, the European stock market shows an increasing trend of joint integration with Northeast Asian stock market. However, the level of integration is not economically significant. Third, the level of market integration between European and global stock markets had temporally increased during the GFC. However, the level returned to its pre-crisis level in the post-crisis era. The overall empirical evidence suggests that, for either European or global stock market portfolio, constructing a portfolio with Northeast Asian stock market would result in a more efficient portfolio. The results in this paper do not support the view of previous empirical studies which suggested the increased level of integration since the GFC. An increased integration is found to be only unique to the crisis period. In sum, the market integration is a dynamic process, and the financial crisis did not uniformly affect the level of stock market integration.
Analysis of different frost indexes and their potential to assess frost based on HAM simulations

To reach the climate goals of 2020 our buildings have to become a lot more energy-efficient. This challenge rests mainly on the shoulders of the renovation sector because new buildings are only a small part of our building stock. Old buildings mainly cannot get insulated on the outside because the facade is historically valuable or because of urban planning restrictions. In those cases interior insulation or - if possible - cavity insulation are the only options. However, these renovation strategies may induce severe risks for the existing structure. One of the main risks is frost damage: the interior insulation lowers the temperature of the exterior facade and decreases the drying potential to the inside which leads to an increased risk of frost damage. Most of the studies that assess the risk of frost damage struggle with the dependency of the highly variable material properties of the facade.
Pollution of Heavy Metals in Some Farms of Torbat-E Jam, Khorasan Razavi Province, Iran

Agricultural intensification is associated with the use of great amounts of agrochemicals that may result in the accumulation of metals in soils, and –subsequently—agricultural products and food chain. Nowadays, this is a major concern for many Iranian agricultural products, necessitating scientific researches on the issue. Therefore, the present study has been conducted to evaluate the level of metal contamination in some agricultural products of Torbat-e Jam, Iran, with the following purposes: (i) to determine concentrations of cadmium (Cd), nickel (Ni), and lead (Pb) in melon (Cucumis melo var. inodorus), sugar beet (Beta vulgaris), and maize (Zea mays) as well as water and soils of some farms in Torbat-e Jam, Iran; and (ii) to examine chemical fertilizers as a possible source of heavy metals' contamination. To do so it has taken some samples from soils, irrigation waters, chemical fertilizers, and crops, measuring their heavy metals contents by means of atomic absorption spectrometry. Results show that heavy metals' concentrations in groundwater and soil were lower than the adopted global standards. Among fertilizers, only Cd content of triple-superphosphate was higher than the standards, leading to a substantial buildup of Cd in the soil, compared to Pb. The greater use of potassium fertilizer has increased Pb concentration in the soil samples of maize farms during the growing season. Among all elements, Pb had the greatest transfer coefficient. It seems that current farm management practices as well as excessive use of chemical fertilizers may further the contamination and loss of soil quality in agricultural systems of the region.
