Tribo-mechanical behaviour of SiC filled glass-epoxy composites at elevated temperatures

Polymer matrix composites are a promising candidate in tribological applications due to possibility of tailoring their properties with special fillers. Several methods have been developed to improve their performance. For instance, the introduction of ceramics such (SiC, Al2O3, TiC, etc.) as within the matrix notably increases the friction coefficient and reduces the wear loss. While glass fibers enhance the toughness of the matrix, silicon carbide shows high hardness, thermal stability and low chemical reactivity, leading to superior friction properties. In this work an attempt was made to evaluate the mechanical properties and tribological behaviour of glass fabric reinforced- epoxy (G-E) composites and silicon carbide filled glass fabric reinforced-epoxy (SiC-G-E) composites. The fabricated wear specimens were tested by using pin-on-disk test rig at various temperatures viz., 30, 60, 90 and 120o C at normal applied loads of 10 N and 20 N. Sliding velocity of the disc of 1.5 m/s was maintained and test was continued for each sample up to a sliding distance of 5000 m. The wear loss in both the composites increases with increase in temperature/applied load and under the same conditions the specific wear rate increases. However, silicon carbide particulate filled G-E composite exhibits lower wear rate with higher coefficient of friction as compared to virgin G-E composite. The elemental composition of worn surface of filler filled composites was quantitatively analyzed by using energy dispersive X-ray spectroscopy. The features of worn surfaces of the specimens tested at higher and lower temperatures at applied normal load of 20 N were examined under scanning electron microscope and also micro mechanism of fractured surfaces were examined through SEM and discussed. Keywords : Glass fabric-epoxy composites; Silicon carbide; Micro mechanism; wear rate and wear mechanisms.
THE EFFECT OF INTEGRATED REPORTING ON CORPORATE FINANCIAL PERFORMANCE: EVIDENCE FROM THAILAND

In today’s world, considering only the economic perspective cannot guarantee corporate sustainability, but the social and environmental perspectives also need to be taken into account. Therefore, corporate actions and activities tend to be balanced between the economic, social, and environmental perspectives. The reporting of information has also changed from the traditional disclosure of purely financial information to reporting which also includes disclosures of nonfinancial information which take into account the social and environmental perspectives. Since companies may no longer wish to provide only a onesided form of information reporting there are a number of forms of reporting which combine both financial and non-financial information reporting such as triple bottom line reporting, sustainable development reporting, and sufficiency economy philosophy reporting. However, there are some limitations in using these reporting frameworks. For example, all these forms of reporting are still voluntary so that companies can pick only positive Abstract

An Analytic Approach to Sparse Hypergraphs: Hypergraph Removal

The use of tools from analysis to approach problems in graph theory has become an active area of research. Usually such methods are applied to problems involving dense graphs and hypergraphs; here we give the an extension of such methods to sparse but pseudorandom hypergraphs. We use this framework to give a proof of hypergraph removal for sub-hypergraphs of sparse random hypergraphs.

Diet and metazoan parasites of silver scabbard fish Lepidopus caudatus from the Great Meteor Seamount (North Atlantic)

Silver scabbard fish Lepidopus caudatus (Euphrasen, 1788) (Trichiuridae) from the Great Meteor Seamount (GMS) in the central eastern Atlantic were studied for diet composition and metazoan parasites. A total of 36 specimens with lengths between 39.1 and 52.2 cm were sampled, which had taken 14 different prey items belonging to 4 major taxonomic groups (Chaetognatha, Crustacea, Mollusca and Teleostei). The most abundant prey organisms were Myctophidae and Euphausiacea, followed by Copepoda (Calanoida), Decapoda, Chaetognatha and Cephalopoda. Fishes were also the dominant prey in terms of biomass. Cannibalism was observed in 7 specimens of subadult L. caudatus. A total of 11 parasite species were identified in/on L. caudatus. We established 9 new host and 8 new locality records. Infestation rates were congruent with diet composition, indicating that parasites were ingested via mesopelagic prey organisms serving as intermediate hosts. The rich parasite fauna in L. caudatus reflects a high diversity of mesopelagic species at the GMS, providing niches for parasites and their intermediate hosts. While several species such as Paradiplectanotrema lepidopi (Monogenea) and Nybelinia lingualis (Cestoda) are typical parasites of L. caudatus, other species such as Sphyriocephalus tergestinus (Cestoda), Anisakis simplex (Nematoda) and Bolbosoma vasculosum (Acanthocephala) seem to be transferred by hosts migrating into the area, indicating an important role of the GMS in the transoceanic distribution patterns of such parasites
University of Groningen Sleeping Worries Away or Worrying Away Sleep? Physiological Evidence on Sleep-Emotion Interactions Talamini,

Recent findings suggest that sleep might serve a role in emotional coping. However, most findings are based on subjective reports of sleep quality, while the relation with underlying sleep physiology is still largely unknown. In this study, the impact of an emotionally distressing experience on the EEG correlates of sleep was assessed. In addition, the association between sleep physiological parameters and the extent of emotional attenuation over sleep was determined. The experimental set up involved presentation of an emotionally neutral or distressing film fragment in the evening, followed by polysomnographic registration of undisturbed, whole-night sleep and assessment of emotional reactivity to film cues on the next evening. We found that emotional distress induced mild sleep deterioration, but also an increase in the proportion of slow wave sleep (SWS) and altered patterning of rapid eye movement (REM) sleep. Indeed, while REM sleep occurrence normally increases over the course of the night, emotional distress flattened this distribution and correlated with an increased number of REM periods. While sleep deterioration was negatively associated to emotional attenuation over sleep, the SWS response was positively related to such attenuation and may form part of a compensatory response to the stressor. Interestingly, trait-like SWS characteristics also correlated positively with the extent of emotion attenuation over sleep. The combined results provide strong evidence for an intimate reciprocal relation between sleep physiology and emotional processing. Moreover, individual differences in subjects’ emotional and sleep responses suggest there may be a coupling of certain emotion and sleep traits into distinct emotional sleep types.

Assessment of Micronutrient Status in Different Land Use Soils in Maybar Lake Watershed of Albuko District, South Wello Zone, North Ethiopia

The study was conducted at the Maybar watershed, which is located in the Albuko District of South Wello Zone in the Amhara National Regional State. The aims of the study were to identify the effects of different land use management practices on the magnitudes and directions of soil fertility using selected physicochemical indicators. Depending on their similarities three forest land representative fields, three grazing land representative fields and three cultivated land representative fields were selected, and from each representative field of land use types, fifteen soil samples were collected from the depths of 0-20 and 20-40 cm each in a radial sampling scheme using an auger. We collected a total of two hundred seventy samples (ninety samples per land use type) of soil which is one hundred thirty five samples from 0-20 cm and one hundred thirty five samples from 20-40 cm of soil horizon. Standard soil analysis for physical and chemical properties was used to analyze the soil samples. The results showed that soil organic carbon declined exponentially following deforestation and subsequent conversion to cultivated land. The imbalance in soil organic carbon addition from the crops and loss of soil organic carbon have led to the continuous decline of soil organic carbon in the cultivated land soils by 41.6% and 86.5% as compared to the forest and grazing lands, respectively. Soil texture (sand, silt and clay) and all of the soils chemical properties studied were significantly affected (P ≤ 0.05 and/or P ≤ 0.01) by land use. Furthermore, considering the soil depths, higher mean values of Fe (38.59 mg/kg) were recorded in the surface (0-20 cm) soil layer than in the subsurface (20-40 cm) depth. The results obtained from the study indicated that the direction and magnitude of changes in soil attributes under land uses reflect the long-term impact of human being on the landscape as the consequences of increasing human as well as livestock populations. All the above values were higher than the critical values of 4.2, 0.2, 0.5 and 1.0mg/kg for Fe, Cu, Zn and Mn, respectively. Also the test analysis showed that the content of Fe, Cu, Zn, Mn and organic matter were significantly higher (P < 0.05) in grazing soils than in forest and cultivated soils, while pH was higher in forest soils. The results of correlation analysis revealed that Cu had significant (P < 0.05) positive correlation with silt content and Fe (r = 0.56* and 0.51*, respectively) but negative and non-significant with clay fraction. Iron and Cu were significant with organic matter (r =0.55* and 0.89**, respectively). The manner in which soils are managed has a major impact on agricultural productivity and its sustainability. Therefore, strategies to feed the expanding population in the country have to seek a sustainable solution that better addresses soil fertility management.
Manifesto for a better management a rational and humanistic view

At the end of the first decade of the 21st century, a disastrous world economic crisis is creating a very difficult situation for many people. The causes of the crisis are many and complex. The reigning economism looks for mechanical causes (excessively low interest rates, "herd" behavior in the real estate and financial bubbles, etc.). Yet bad management by the people in charge of many of the institutions affected has been crucial. Paradoxically, management can be responsible both for great successes and for great failures. The same term, "management", can refer to very different concepts. The emphasis on immediate effectiveness in terms of financial results (which always turn out to be short-term) as the sole purpose betrays a pessimistic conception of human beings as creatures that react only to economic stimuli, thus neglecting other dimensions that are fundamental to good management, and leading us to the present crisis. In this paper we aim to establish the starting points for good management, explain why management is important for society, critically analyze the present economic crisis and the practices and concepts that led to it, and propose the foundations of a better conception of management for the future, rejecting the culture of shortsightedness. We therefore set forth: a) Which concepts of the company and of management are conducive to management practices that are good for society as a whole. b) Why management is important for the development of human societies in general. c) What is good and what is bad about the practices and theories that currently dominate the world of management. d) How to prevent bad theory and bad practice, including bad applications of good theory, from influencing the broader trends.
Banking Theory, Deposit Insurance, and Bank Regulation

The last several years have seen extensive change in the U.S. banking industry. ' In the 1950s and 1960s the banking industry was a symbol of stability. By contrast, recent years have seen the greatest frequency of bank failures since the Great Depression. During the same period, the banking environment has undergone the most significant changes since 1933, when the Glass-Steagall Act laid down the ideas underlying the modern regulatory environment. The recent changes include new competitors to banks, new technology, new floating rate contracts, increases in interstate banking, and various regulatory reductions and changes. Some of these changes are accelerated by the current high rate of bank failure; many of the changes are driven by technology and competition and are inevitable. One implication of all these changes is that we now face policy decisions that will affect the future course of the banking industry. Since the current environment is largely outside our past experience, we need theory to extrapolate from past experience to our current situation. The purpose of this paper is to summarize the policy implications of existing economic models of the banking industry and to examine some current recommendations in light of the theory. Our conclusions contrast with the traditional view in economics and with several conclusions in Kareken's (in this issue) lead piece in this symposium. Most references to banks in the microeconomics literature have not looked at banking at the industry level. The bank management litera-
The Relation between Academic Achievement and Emotional Intelligence in Iranian Students: A Meta-Analysis

Summary Academic achievement is one of the most important concepts in the field of education. Although emotional intelligence, as a key factor in academic achievement, has been studied in various studies, yet the results obtained are not in harmony with each other and the topic is yet under debate. In order to fill in this informational vacuum, the present research was undergone using a meta-analysis method. In order to make a thorough search to find articles within the Iranian context, key words such as “Emotional Intelligence” AND (Emotional OR Intelligence) AND “academic achievement” OR “academic status” AND “Student” AND “Iran”, were used without limitation in dates or language in the following sites: Medline, Scopus, ScienceDirect, Web of Knowledge, Ovid, Wiley, Google Scholar, and Persian databases such as SID, Irandoc and Magiran. The random effect model was utilized for statistical pooling. A total of 23 articles were chosen to enter the meta-analysis. The pooled results showed a meaningful relationship between emotional intelligence and academic achievement (Pooled Correlation = 0.157; 95% CI, 0.081-0.231). The Cochran Q (Q = 145:126, p = 0.000) and I2 = 84.84% index indicated a high heterogeneity among the articles entering the meta-analysis. In subgroup analysis, the students in state universities had more summary effect (0.177; 95% CI, 0.085 - 0.267) compared to the ones studying in private ones (0.118; 95% CI, 0.024-0.255). No sign of publication bias was found. A weak correlation was seen between emotional intelligence and educational achievement in the context of Iranian university students. It seems that the relationship of these concepts may be affected by other factors in this setting, so this calls for further studies in this field.
Water soluble aerosols and gases at a UK background site – Part 1: Controls of PM 2.5 and PM 10 aerosol composition

Abstract. There is limited availability of long-term, high temporal resolution, chemically speciated aerosol measurements which can provide further insight into the health and environmental impacts of particulate matter. The Monitor for AeRosols and Gases (MARGA, Applikon B.V., NL) allows for the characterisation of the inorganic components of PM10 and PM 2.5 (NH4+, NO3-, SO42-, Cl-, Na+, K+, Ca2+, Mg2+) and inorganic reactive gases (NH3, SO2, HCl, HONO and HNO3) at hourly resolution. The following study presents 6.5 years (June 2006 to December 2012) of quasi-continuous observations of PM2.5 and PM10 using the MARGA at the UK EMEP supersite, Auchencorth Moss, SE Scotland. Auchencorth Moss was found to be representative of a remote European site with average total water soluble inorganic mass of PM2.5 of 3.82 μg m−3. Anthropogenically derived secondary inorganic aerosols (sum of NH4+, NO3- and nss-SO42−) were the dominating species (63 %) of PM2.5. In terms of equivalent concentrations, NH4+ provided the single largest contribution to PM2.5 fraction in all seasons. Sea salt was the main component (73 %) of the PMcoarse fraction (PM10-PM2.5), though NO3- was also found to make a relatively large contribution to the measured mass (17 %) providing evidence of considerable processing of sea salt in the coarse mode. There was on occasions evidence of aerosol from combustion events being transported to the site in 2012 as high K+ concentrations (deviating from the known ratio in sea salt) coincided with increases in black carbon at the site. Pollution events in PM10 (defined as concentrations > 12 μg m−3) were on average dominated by NH4+ and NO3-, where smaller loadings at the site tended to be dominated by sea salt. As with other western European sites, the charge balance of the inorganic components resolved were biased towards cations, suggesting the aerosol was basic or more likely that organic acids contributed to the charge balance. This study demonstrates the UK background atmospheric composition is primarily driven by meteorology with sea salt dominating air masses from the Atlantic Ocean and the Arctic, whereas secondary inorganic aerosols tended to dominate air masses from continental Europe.
Correlation between speed, agility and quickness (SAQ) in elite young soccer players

The purpose of this study was to determine the correlation between the speed, agility and quickness, and to determine the correlation between tests with and without the ball in young soccer players. Research was carried out on a sample of 25 elite soccer players from the Serbian U-16 national team, (aged 15.19±0.32 ; height176.04±6.00 cm ; body mass 65.19±9.41 kg). The participants were tested on a 10-m Sprint (B10S), 30-m Sprint (B30S), Flying 20-m Sprint (B20S), Zigzag test (CC) and Zigzag With the Ball (CCL). Significant relationships were found between test CC and B30S (r=0.560), as well as between test CC and B20S (r=0.603). There were no significant relationships between CC and B10S (r=0.323). The agility test with the ball (CCL) has not shown significant correlation with speed and quickness (r=0.093-0.247). The SAQ training method has made training much more applied than previously although it is mainly represented by the movements during which the control and contact with the ball are at a minimum. This causes the loss of specificity between exercises and demands in the demonstration both during the testing and the game. This study has confirmed that the structure of the agility with the ball is much more complex in comparison with the one without the ball. In addition, this research has shown that the basic skills without the ball have much stronger relation among speed, agility and quickness than the skills with the ball.
The Grizzly Bears of Yellowstone: Their Ecology in the Yellowstone Ecosystem, 1959-1970

In 1959, John and Frank Craighead, along with a dedicated team of students and professional colleagues, began their pioneering and controversial study of the grizzly bear in the Yellowstone ecosystem. "The Grizzly Bears of Yellowstone" is the culmination of that research. It captures both the history and the science of how the Yellowstone study evolved into a lifelong battle to protect and perpetuate the grizzly bear.John J. Craighead and his longtime research colleagues, Jay S. Sumner and John A. Mitchell, have brought together years of data detailing the natural history, reproductive biology, social behavior, population dynamics, and habitat use patterns of the grizzly bear population in the Yellowstone ecosystem from 1959 through 1992, as well as the results of complementary studies conducted by John Craighead in wilderness areas of Montana and Alaska. Their interpretations of the data have far-reaching management implications, not only for the grizzly but for the holistic management of large regional ecosystems. This study is an example of long-term ecological research that is unparalleled in its combination of foresight, continuity of effort, innovation of field techniques, and monumental scholarship.
Evaluated the Success of Fractionally Integrated-GARCH Models on Prediction Stock Market Return Volatility in Gulf Arab Stock Markets

This paper evaluated the different Fractionally Integrated-GARCH Models (FIGARCH BBM's, FIGARCH Chung, FIEGARCH, FIAPARCH BBM's, FIAPARCH Chung, and HYGARCH). This is the first research to use six different Fractionally Integrated-GARCH Models. Most research compares one of Fractionally Integrated-GARCH Models with the traditional GARCH, EGARCH, GJG-GARCH, IGARCH, and APGARCH. To do so, daily returns of Gulf Cooperation Council (GCC) Stock Markets analyzed, covering the period 1995 to 2015. Both the Superior Predictive Ability and the Model Confidence Set tests were used to identify the best fitting models of each country. The results reveal that FIGARCH BBM is the best fitting model for UAE, KSA, and Bahrain. FIEGARCH is the best fitting model for Kuwait. FIGARCH Chung is the best fitting model for Qatar. Only the results for Oman were mixed between FIGARCH BBM and FIAPARCH BBM models.
