Syddansk Universitet Characterization of Metal-Doped Methylated Microporous Silica for Molecular Separations El-Feky,

Novel silica xerogels are prepared and developed by sol-gel method in the present study. The preparation involves cobalt-doping within the organic templated silica matrices, where methyltriethoxysilane (MTES), which contains methyl groups as a covalently bonded organic template is used. The synthesis and surface properties of cobalt-doped methylated microporous silica xerogels with different MTES and cobalt content are revealed by surface and microstructural techniques, such as TGA, FTIR, X-ray and N2 adsorption measurements. The doping process enhances the thermal stability of the silica xerogels up to ~ 560 °C in oxidizing atmosphere. Besides, this process has no significant effect on the incorporation of the organic template within the silica matrix. As result of the promoted densification of the xerogels either by increasing MTES content and heat treatment, there is structural change of the silica xerogels such as decreasing the micropore volume and broadening of the pore size distribution. Heat treatment and increasing the cobalt oxide content from 5 to 10% weight ratio resulted in samples with approximately the same structural parameters. This suggests that the cobalt particles are homogeneously dispersed in the silica matrix. The novel silica xerogels exhibit trend toward micropores formation suggesting that these doped silica xerogels can be precursor materials for molecular sieve silica membranes applications. Two silica membranes, hydrophobic and cobalt-doped hydrophobic, are prepared and their performance is examined by the study of transport of He, H2 and N2. Preliminary results show that the microporous structure obtained in the unsupported cobalt-doped hydrophobic material are preserved after coating inside the tubular support.
Distribution of multidrug resistance associated proteins in different histological subtypes and stages in operable non small cell lung cancer. A tissue microarray study

The aim of this retrospective study was to comparatively investigate the expression of the three drug-resistance related proteins P-glycoprotein (P-gp), multidrugresistance protein 1 (MRP1), and lung resistence protein (LRP), in non-small cell lung cancer (NSCLC) tissues using tissue microarray technology. Methods: Tumor specimens from 179 patients were analyzed by immunohistochemistry and data were statistically analyzed by SPSS. Results: The mean expression levels of tumor tissues in the case of P-gp and LRP did not exceed the one of normal epithelia, while MRP1 was significantly enhanced in NSCLC. No associations were observed between higher grading and P-glycoprotein expression (p <0.8) as well as lower grading and MRP1 expression in the case of adenocarcinoma (p <0.05). We also did not find any association between the immunohistochemical expression of MrP1, Lrp, Pgp, grading and staging. Conclusions: Ourdata point towards a major role of MRP1 in the intrinsic reatment resistance of NSCLC.
LEARNING STRATEGIES AND MOTIVATIONAL PATTERNS IN DEGREE OF THE SCHOOL OF ECONOMIC AND BUSINESS

In this study the main purpose is to explore relations between students' learning strategies and their motivational patterns in the course Introduction to Economic Statistics of University of Oviedo. The course Introduction to Economic Statistics is a basic training in a Business Administration degree. It is a common course for the degrees in Economics, Accounting and Finance and Labour Relations and Human Resources, which are also part of the course catalogue of the School of Economics and Business. The course has no prerequisites. It is recommended that the student should be competent in mathematics, in any of its options at secondary (high school) level. The evaluation of the course is based on continuous assessment throughout the course and final exam. The results of final grades are very different between the four degrees. In this study, the differences between the learning and motivational patterns employed by the students of the degrees are analyzed. The correlations of motivation and learning strategies with final grades and/or continuous assessment are exposed. The data were collected thorough the Learning Strategies and Motivation Questionnaire. Participants were 169 undergraduates. The results about the disparities between grades could be useful to correct teaching practices and evaluation performances in some grades.
What makes people refuse to lie? : understanding pure lie aversion

In this paper, I examine pure lie aversion in a controlled experiment. When both the liar and the person that is being lied to benefits from the lie, why do some people still refuse to lie? I use treatments to capture pure lie aversion and examine the role of context, content and the effect when using intuition. Pure lie aversion is presumably present in all lies, which means my findings may be applicable to a wide range of real-world settings.
PARTICLE-TURBULENCE INTERACTIONS IN ATMOSPHERIC CLOUDS

▪ Abstract Turbulence is ubiquitous in atmospheric clouds, which have enormous turbulence Reynolds numbers owing to the large range of spatial scales present. Indeed, the ratio of energy-containing and dissipative length scales is on the order of 105 for a typical convective cloud, with a corresponding large-eddy Reynolds number on the order of 106 to 107. A characteristic trait of high-Reynolds-number turbulence is strong intermittency in energy dissipation, Lagrangian acceleration, and scalar gradients at small scales. Microscale properties of clouds are determined to a great extent by thermodynamic and fluid-mechanical interactions between droplets and the surrounding air, all of which take place at small spatial scales. Furthermore, these microscale properties of clouds affect the efficiency with which clouds produce rain as well as the nature of their interaction with atmospheric radiation and chemical species. It is expected, therefore, that fine-scale turbulence is of direct importance to the evolu.
Research and Trends in the Studies of Native & Non-Native Speaker Teachers of Languages: A Review on Selected Researches and Theses.

Recruiting and employing native speaker teachers of English Language (NST) in non-native speakers’ context are widely practised in countries which learn and use the target language taught by the native speaker teachers (NST) as either as a second or a foreign language. This paper reviews selected journals and thesis on the issues of Native and Non-native Speaker Teachers (NST & NNST). It covers on students’, as well as the Native and Non-Native Speaker Teachers’ (NNST) self-perceptions and attitudes. This review discovers almost the same pattern of students’ attitudes and perceptions towards native speaker teachers. Most studies reviewed indicate that most of the non-native learners of the target language have positive attitude towards native speaker teachers. They view native speaker teachers as the model of the target language learnt and believe that the native speaker teachers could provide a great example in learning pronunciation and speaking skill. In addition, this review also identifies that learners believe that their non-native teachers are compatible in teaching the language as they have experienced in being second language learners. As such, they are more empathic and are able to apply the suitable teaching approaches for the learners in learning the language. In contrast, the learners view their non-native speaker teachers are weak in teaching oral communication skills as they believe that in order to learn communication skills, native speaker models are required. However, the learners still prefer the collaborative teaching of native and non-native speaker teachers of the language when learning the target language. This is because they take the native speaker teachers as their model to learn the language and the non-native speaker teachers as their interpreter. Nonetheless, this review also finds that learners value both native and non-native teachers of the language.
White Dwarf Cosmochronometry. I. Monte Carlo Simulations of Proper-Motion- and Magnitude-limited Samples using Schmidt's 1/Vmax Estimator

Observationally, white dwarf stars are a remarkably homogeneous class with a minimum observed Teff ~ 4000 K. Theoretically, the physics that determines their cooling timescales is relatively more straightforward than that which determines main-sequence evolutionary timescales. As a result, the white dwarf luminosity function has for the last decade been used as a probe of the age and star formation rate of the Galactic disk, providing an estimated local disk age of ~10 Gyr with estimated total uncertainties of roughly 20%. A long-standing criticism of the technique is that the reality of the reported downturn in the luminosity function (LF) hinges on just a handful of stars and on statistical arguments that fainter (older) objects would have been observed were they present. Indeed, the likely statistical variations of these small-number samples represent one of the primary uncertainties in the derived Galactic age, and the behavior of Schmidt's 1/Vmax estimator in this limit is not well understood. In this work, we explore these uncertainties numerically by means of a Monte Carlo population synthesis code that simulates the kinematics and relative numbers of cooling white dwarfs. The "observationally selected" subsamples are drawn using typical proper motion and V-magnitude limits. The corresponding 1/Vmax LFs are then computed and compared to the input-integrated LFs. The results from our (noise-free) data suggest that (1) Schmidt's 1/Vmax technique is a reliable and well-behaved estimator of the true space density with typical uncertainties of ~50% for 50 point samples and 25% for 200 point samples; (2) the age uncertainties quoted in previously published observational studies of the LF are consistent with uncertainties in the Monte Carlo results—specifically, there is a ~15% and ≲10% observational uncertainty in the ages inferred from 50 point and 200 point samples, respectively; and (3) the large statistical variations in the bright end of these LFs—even in the large-N limit—preclude using the white dwarf LF to obtain an estimate of the recent star formation rate as a function of time.
Are groups ‘less behavioral’? The case of anchoring

Economic small group research points to groups as more rational decision-makers in numerous economic situations. However, no attempts have been made to investigate whether groups are affected similarly by behavioral biases that are pervasive for individuals. If groups were also able to more effectively avoid these biases, the relevance of biases in actual economic contexts dominated by group decision-making might be questioned. We consider the case of anchoring as a prime example of a well-established, robust bias. Individual and group biasedness in three economically relevant domains are compared: factual knowledge, probability estimates and price valuations. In contrast to previous anchoring studies, we find groups to successfully reduce, albeit not eliminate, anchoring in the factual knowledge domain. For the other two domains, groups and individuals are equally biased by external anchors. Group cooperation thus reduces biases for predominantly intellective tasks only, while no such reduction is achieved when judgmental aspects are involved.
Chapter 5 Thromboembolism in Renal Diseases

Patients with renal diseases are prone to both thrombosis and bleeding, as they have profound changes in all three classic components of coagulation, defined approximately 150 years ago by Virchow: blood flow, vessel wall (endothelial injury), and coagulation properties of the blood (e.g., coagulation and fibrinolytic systems and platelets). The pro‐ thrombotic state in chronic kidney disease (CKD), glomerular diseases (including sys‐ temic lupus and vasculitis), and some less frequent conditions (idiopathic retroperitoneal fibrosis, antiphospholipid syndrome, hemolytic‐uremic syndrome, etc.) is associated with vascular endothelial damage, increase in certain coagulation and antifibrinolytic factors, decrease in anticoagulation proteins, dyslipidemia, hypoalbuminemia, changes in platelet membranes, hemo‐ and peritoneal dialysis and heparin treatment, increased microRNAs and circulating microparticles, antiphospholipid antibodies, nephrotic syn‐ drome, anemia with high platelet count, and so on. Nevertheless, the same patients have substantially increased risk of bleeding due to platelet dysfunction and intake of certain medications (antiaggregants, heparin and low‐molecular weight heparins, and anemia). The aim of this review is to present the main thrombo‐embolic risk factors in a wide vari‐ ety of patients with renal diseases, including chronic glomerulonephritis (primary and secondary), chronic renal disease, and idiopathic retroperitoneal fibrosis. We have evalu‐ ated the risk factors for arterial and venous thromboses in a wide variety of renal patients with both glomerular and non‐glomerular diseases, including the presence of nephrotic syndrome, inborn and acquired coagulation defects (i.e., factor V Leiden, MTHFR gene mutation, 20210 prothrombin gene mutation, and antiphospholipid antibodies), cortico‐ steroid treatment, and dyslipidemia. We are describing the results of these investigations and suggesting prophylactic anticoagulant strategies in such patients. Multiple risk fac‐ tors influence the coagulation system in renal disease leading to both hypercoagulation and hemorrhagic diathesis. Therefore, renal patients should be thoroughly investigated for coagulation abnormalities, especially if pathogenic (i.e., corticosteroid and immu‐ nosuppressive) and anticoagulation treatment is to be initiated. Moreover, the doses of anticoagulant/antiaggregant and hemostatic medications should be considered carefully, having in mind the underlying diseases and risk factors, renal function, and concomitant treatment. © 2017 The Author(s).

Optimal randomness certification in the quantum steering and prepare-and-measure scenarios

Quantum mechanics predicts the existence of intrinsically random processes. Contrary to classical randomness, this lack of predictability can not be attributed to ignorance or lack of control. Here we find the optimal method to quantify the amount of local or global randomness that can be extracted in two scenarios: (i) the quantum steering scenario, where two parties measure a bipartite system in an unknown state but one of them does not trust his measurement apparatus, and (ii) the prepare-and-measure scenario, where additionally the quantum state is known. We use our methods to compute the maximal amount of local and global randomness that can be certified by measuring systems subject to noise and losses and show that local randomness can be certified from a single measurement if and only if the detectors used in the test have detection efficiency higher than 50%.
Inequality Indebtedness and Financial Crises

This work is an empirical contribution that investigates the presence of a relationship among income inequality, household indebtedness and the erup- tion of systemic banking crises (namely the I-I-C nexus). We test this hy- pothesis on a panel of 31 countries over the period 1980-2012 within four different scenarios. We find strong evidence of a statistically significant asso- ciation between income inequality and systemic banking crises via household indebtedness (the I-I-C nexus) regardless of the specification and the estima- tion technique chosen. However, we find no evidence of a feedback effect of a systemic banking crisis on income inequality, at least in the short run. We also find that economies characterized by highly liberalized financial mar- kets are more prone to experience such a nexus. These results suggest that reforming the architecture of financial regulation and supervision is still an important issues. However, it is a necessary but not sufficient condition in order to ensure financial stability.
Electrocatalysis at Electrodes for VanadiumRedox Flow Batteries

Flow batteries (also: redox batteries or redox flow batteries RFB) are briefly introduced as systems for conversion and storage of electrical energy into chemical energy and back. Their place in the wide range of systems and processes for energy conversion and storage is outlined. Acceleration of electrochemical charge transfer for vanadium-based redox systems desired for improved performance efficiency of these systems is reviewed in detail; relevant data pertaining to other redox systems are added when possibly meriting attention. An attempt is made to separate effects simply caused by enlarged electrochemically active surface area and true (specific) electrocatalytic activity. Because this requires proper definition of the experimental setup and careful examination of experimental results, electrochemical methods employed in the reviewed studies are described first.
The relationship between corporate governance and company performance in concentrated ownership systems: The case of Germany

This article presents the results of empirical research of the impact of corporate governance system elements (ownership structures and board characteristics) and company performance in the economies with concentrated ownership. Major goals of this study were to develop the empirical methodology allowing for causal relationship between ownership structure elements and corporate performance and to test the methodology using the high-quality data from the developed market with concentrated ownership. The panel data sample of 270 German companies for the period of 2000-2006, originally collected in Sautner & Villalonga (2009) study and supplemented with additional data by the authors of this article, was used for empirical testing 9 of the hypotheses. Using instrumental variables and simultaneous equations methods to identify causality in the relationship between corporate governance and corporate performance, we found negative impact of insider ownership on performance and positive effect for institutional investors ownership. At the same time, causality in the relationship between board characteristics and company performance cannot be established in the absence of so-called natural experiment, i.e. forced change in board composition due to government policy measures (Black & Kim 2008), due to the lack of instrumental variables for board characteristics. Two main policy implications of the analysis follow. Firstly, limitations on cross-listing of the companies in foreign stock markets result in lower institutional investors ownership and thus translate in worse companies’ performance. Secondly, the equilibrium view of companies’ ownership structures, argued for in Demsetz & Lehn (1985) study, is not supported for concentrated ownership systems with high transaction costs of ownership structures reshuffling (e.g. in case of high capital gains taxes), so governments should adopt any measures, which result in high ownership stakes transferring costs, with caution. The empirical methodology developed in this article may be further used in the research on emerging market data; the study of relationship between corporate governance and company performance under the impact of financial crisis is another promising area of study.

Minimization of SO2 Emissions at ADGAS (Das Island, UAE): I- Current vs.Modified Schemes

The objective of this work is to explore feasible technologies to minimize SO2 emissions from ADGAS and investigate the impact of implementing such modifications on the ambient air quality at the Island. In order to achieve this, two SO2 emission minimization schemes have been proposed; a Fuel Gas Sweetening (FGS) scheme and a Flue Gas Desulfurization (FGD) scheme.The FGS scheme involves (1) directing most of the H2S in the fuel gas to the Sulfur Recovery Units (SRUs) where it is converted to elemental sulfur. The unconverted H2S will be routed to the SRUs’ incinerators where it is oxidized to SO2, and (2) revamping the UGAs internals (by replacing current packing with an approved higher efficiency packing) in order to produce a sweeter fuel gas. The FGD scheme involves installation of SW-FGD units downstream the SRUs’ incinerators where the SO2 in the flue gas is scrubbed by the plant spent seawater in a dedicated packed bed absorber and converting it to harmless sulfate ions (natural constituents of the seawater) that will be safely disposed to the sea. The FGS scheme is expected to reduce the H2S content in the fuel gas by 94% and result in decreasing the total SO2 emissions due to fuel gas usage by 98%. The FGD scheme is expected to reduce the SO2 emissions due to incomplete sulfur recovery in the SRUs by 99.5%. Implementation of both schemes is expected to reduce the total SO2 emissions by 77%. Most of the remaining SO2 emissions (23%) are due to the continuous flaring of the flash gas in the plant. In Part II of this work, the BREEZE AERMOD Pro Software is used to predict the SO2 Ground Level Concentration (GLC) for the current and modified SO2 minimization schemes. Compliance with the country limits and challenge with future regulatory standards have been examined.
Students’ Competences and Entrepreneurs’ Expectations: The First Stage of the SYNERGY Project Evaluation

The article presents the results of a research on students’ competencies self-esteem. Competencies were defined as a synthesis of three components: knowledge, skills and attitudes. The study was performed in the areas identified by the representatives of the business, as competitiveness key factors in the job market. The research was conducted in the years 2009 - 2012, on a sample of 1,831 students, under the “SYNERGY – MCSU Faculty of Economics students’ competences development by gaining practical knowledge” project. The SYNERGY project was co-financed by the European Union from European Social Fund and realized by the Department of Economics Maria Curie- Sklodowska University (MCSU). The purpose of this article is the to show which areas of knowledge, skills, and attitudes are considered to be essential for business owners and business representatives, as well as what is the level of self-esteem of this competencies among the students of economics. The article consists of two parts. In the first part authors present the characteristics of the SYNERGY project: basic information, project objectives and activities realized in the framework of the project, for students, enterprises and business organizations. The second part presents the results of the research on students' of economics self-assessment in the area of presented knowledge, skills and attitudes. Authors present areas of knowledge that were characterized by high and low level of self-esteem. The paper also shows the skills that are desirable from the business point of view, but in the opinion of students require special attention and development. In the last part of the article authors present, whether and how the competencies self-esteem level depends on respondents’ gender, age, place of residence, year and course of study? The paper presents also the key findings of the study, as well as examples of activities that are necessary to raise the level of knowledge, skills and to shape the attitudes of business students.
