Accumulation variability derived from an ice core from coastal Dronning Maud Land, Antarctica

Abstract A 100 m long ice core was retrieved from the coastal area of Dronning Maud Land (DML), Antarctica, in the 2000/01 austral summer. The core was dated to AD 1737 by identification of volcanic horizons in dielectrical profiling and electrical conductivity measurement records in combination with seasonal layer counting from high-resolution oxygen isotope (δ18O) data. A mean long-term accumulation rate of 0.29 ma–1w.e. was derived from the high-resolution δ18O record as well as accumulation rates during periods in between the identified volcanic horizons. A statistically significant decrease in accumulation was found from about 1920 to the present. A comparison with other coastal ice cores from DML suggests that this is a regional pattern.
A Computational Model to Assess Poststenting Wall Stresses Dependence on Plaque Structure and Stenosis Severity in Coronary Artery

The current study presents computational models to investigate the poststenting hemodynamic stresses and internal stresses over/within the diseased walls of coronary arteries which are in different states of atherosclerotic plaque. The finite element method is applied to build the axisymmetric models which include the plaque, arterial wall, and stent struts. The study takes into account the mechanical effects of the opening pressure and its association with the plaque severity and the morphology. The wall shear stresses and the von Mises stresses within the stented coronary arteries show their strong dependence on the plaque structure, particularly the fibrous cap thickness. Higher stresses occur in severely stenosed coronaries with a thinner fibrous cap. Large stress concentrations around the stent struts cause injury or damage to the vessel wall which is linked to the mechanism of restenosis. The in-stent restenosis rate is also highly dependent on the opening pressure, to the extent that stenosed artery is expanded, and geometry of the stent struts. The present study demonstrates, for the first time, that the restenosis is to be viewed as a consequence of biomechanical design of a stent repeating unit, the opening pressure, and the severity and morphology of the plaque.
Partitioning the effects of changes in nitrate availability and phytoplankton community structure on relative nitrate uptake

The uptake of dissolved nitrogen by different assemblages of phytoplankton was deter- mined during 4 seasonal surveys carried out in the northwest sector of the Alboran Sea. The study area was characterized by stratification of the water column from spring to autumn, leading to very low nutrient concentrations in the euphotic zone; in particular, nitrate was below the detection limit at numerous stations in autumn. In winter and spring, the potential limitation of phytoplankton growth by nitrate was alleviated at some stations by upwelling of the nutrient-enriched Levantine Intermediate Water (LIW). The values of relative NO3 - uptake (the proportion of nitrate to total N uptake) were highly variable (ranging from 0.01 to 0.8), even during single surveys. At most of the sampling stations during the stratification period, the relative nitrate uptake was <0.2 at the surface, but increased at the depth of the sub-surface chlorophyll a fluorescence maximum (SFM). At the surface, relative nitrate uptake and nitrate concentrations were strongly correlated, and about 82% of the relative nitrate uptake variabil- ity was accounted for by simultaneous changes in the nitrate concentrations and the micro-plankton chlorophyll a size fractions. These changes were related to modifications in upwelling intensity, as determined by variability in surface salinity. In contrast, relative nitrate uptake was not correlated with nitrate concentrations in the SFM samples, where the mean nitrate concentration increased 3-fold with respect to the surface value. On average, the micro-phytoplankton in these samples collected at the SFM was dominated by diatoms, the abundance of which ranged from 24 to 960 cells ml -1 . This variability in diatom cell abundance explained about 52% of the variability of relative nitrate uptake at this depth level. Therefore, our data demonstrate that the proposed relationship between relative nitrate uptake and large phytoplankton was most evident at non-limiting nitrate concentrations.

Acculturation and Self-rated Health among Foreign Women in Korea

The main purpose of this paper is to examine the relationship between acculturation and health among the growing female foreign population in Korea. To capture different aspects of acculturation and their association with self-rated health among foreign women, three measures of acculturation, that is, Korean speaking proficiency, age at arrival, and length of residency were used. This paper also adopted social support, life satisfaction, and discrimination variables as covariates and examined other socioeconomic variables and discrimination as effect modifiers in its examination of the association between acculturation and self-rated health. Micro-data from the 2009 Korean National Multi-Cultural Family Survey was analyzed. Results of chi-square tests, t tests and multivariate-adjusted logistic regression analysis showed that greater acculturation in terms of Korean language proficiency is associated with better health. It is interpreted that better language capability increases access to health related information. It was also found that increased age of arrival of foreign women and shorter length of residency in Korea tend to be associated with better self-rated health. Analysis of interaction revealed that level of education, income, and discrimination are significant effect modifiers for the association between Korean speaking proficiency and self-rated health status. For foreign women with higher education and income and those with an experience of being discriminated against, the gap in self-reported health by Korean speaking proficiency tends to be larger. Plausible explanations and implications of these findings are discussed in this paper.
Intracellular Lipase Production by Yarrowia Lipolytica Using Different Carbon Sources

Yarrowia lipolytica is capable of producing lipase, an enzyme widely used in industry for, under conditions microaquosas, catalyzing the synthesis of esters. The extracellular lipase produced by this yeast has been fully characterized and has wide range of application, but the intracellular and cell-bound fractions are still little reported production and characterization. The application of intracellular and cell-bound lipases in industrial processes can reduce the purification cost, facilitating the use of this enzyme. Therefore, the objective of this study was to evaluate the production of intracellular lipases induced by different carbon sources. We investigated the intracellular lipase production by Yarrowia lipolytica strain IMUFRJ 50682 using glucose, glycerol, crude glycerol, olive oil and frying oil. The methodology for the intracellular and cell-bound lipase extraction was standardized. Cell growth, concentration of glucose and glycerol was accompanied. Measures of enzymatic activity were carried out using spectrophotometric method. Y. lipolytica cells presenting in the form of hyphae were more sensitive to the two extraction processes used and the extraction with ultrasound possible to obtain activity values to cell bound fraction up to 9 times higher than those obtained with the mechanical extraction. Glycerol and glycerin were not effective for induction of enzymatic fractions. Glucose induced activity in extracellular fraction. Olive oil and waste frying oil were the best inducers for intracellular fractions. Frying oil was a good inductor to obtain intracellular lipases and the values of hydrolytic activity were similar to values obtained with the olive oil. In presence of frying oil, the hydrolytic activity was 12,19 U/g, in 24h of growth and when olive oil was used like inductor, the enzyme activity to the cell bound fraction reaching activity of 12,14 U/g in 24h of the experiment. Therefore, the intracellular fractions of Yarrowia lipolytica lipase can be induced efficiently and represent an interesting alternative for developing technology to the use of biomass in industrial processes.

Therefore, the research was carried to evaluate effects of fast neutron irradiation on the morphology and phenotype of Lagos spinach, with the aim of inducing useful agronomical traits for selection of desirable genotypes that could be used for large scale production. The Celosia argentia (Red accession) that were used for the experiment were obtained from local far
Impact of Restatement Characteristics and Subsequent Earnings Management on Post-Sox Executive Turnover

Understanding whether the likelihood of management turnover related to financial restatements changes after SOX is especially important because restatements have become much more common, with over 10% of publicly traded companies announcing restatements in 2006 (Johnson 2008). By surveying post-SOX company restatements, this study focuses on restatement characteristics as well as related management behavior, and provides insights into their consequences. Our findings provide evidence that the likelihood of CEO or CFO turnover increases for companies with higher restatement severity. Specifically, restatement characteristics, including core-earnings and magnitude of amounts, significantly affect the likelihood of management turnover. Additionally, when restatements are prompted by companies, management turnover is associated with the magnitude of overstated amount on income and/or restatements affecting core earnings. In addition, after controlling for the restatement severity, our empirical results provide strong evidence that when post-SOX executives window-dress earnings to portray a more favorable earnings picture, they are more likely to be terminated following financial restatements.

Effect of superhydrophobic surface of titanium on staphylococcus aureus adhesion

Despite the systemic antibiotics prophylaxis, orthopedic implants still remain highly susceptible to bacterial adhesion and resulting in device-associated infection. Surface modification is an effective way to decrease bacterial adhesion. In this study, we prepared surfaces with different wettability on titanium surface based on TiO2 nanotube to examine the effect of bacterial adhesion. Firstly, titanium plates were calcined to form hydrophilic TiO2 nanotube films of anatase phase. Subsequently, the nanotube films and inoxidized titaniums were treated with 1H, 1H, 2H, 2H-perfluorooctyl-triethoxysilane (PTES), forming superhydrophobic and hydrophobic surfaces. Observed by SEM and contact angle measurements, the different surfaces have different characteristics. Staphylococcus aureus (SA) adhesion on different surfaces was evaluated. Our experiment results show that the superhydrophobic surface has contact angles of water greater than 150° and also shows high resistance to bacterial contamination. It is indicated that superhydrophobic surface may be a factor to reduce device-associated infection and could be used in clinical practice.
Vertical segregation in higher education: The case study of the Republic of Serbia

The gender role hierarchy in the Republic of Serbia is an inspirational topic on several grounds: first, this is a specific issue within a wider gender equality problem, which has recently become the priority of structural reforms; second, it is a separate segment of gender segregation, the research issue unjustifiably ignored by the domestic academic community; finally, it is just a piece of the 'puzzle' that reflects the situation in the gender inequality field, but exactly the one which neither national nor European statistics provide detailed information for. The above-mentioned reasons represent the basic motivation for writing this paper. In order to determine whether the position of women in science varies according to their position on the career scale, as it usually happens all over Europe, we shall examine the situation in the higher education system in the Republic of Serbia. That is why we apply the methodological procedures of descriptive statistics to the micro-data obtained from the Ministry of Education, Science and Technological Development in order to calculate the following relative indicators: the teaching staff structure by gender and grades across different fields of science and the glass ceiling index. We believe that such a relatively precise insight into the range of vertical segregation could be useful in conceiving future initiatives aimed at the systemic introduction of a gender perspective in the adoption, implementation and monitoring of public policies.
The Antecedent and Consequence of Organizational Commitment and Job Satisfaction

This study aims to examine and analyze the effect of transformational leadership on organizational commitment, job satisfaction and performance of servants. Design of this study using survey method with data collection in cross-section through a questionnaire. The sampling is done via stratified random sampling using 197 servants. Analysis of the data used in testing hypothesis is Structural Equation Modeling. Results of the study provide evidence that transformational leadership significantly affect the increase organizational commitment and job satisfaction. However, a good transformational leadership is not able to improve the performance of servants if it is not supported by organizational commitment and high job satisfaction. Organizational commitment and job satisfaction act as complete mediation in explaining the effect of transformational leadership on servant’s performance.
Phosphor in der Entstehung der urämischen Mediasklerose

Phosphate in the Pathogenesis of Uremic Media Sclerosis. As part of a number of vital metabolic processes and signalling pathways and constituent of the skeleton, phosphorus plays a number of vital roles. Regulatory mecha nisms aiming to maintain a balanced phosphate equilibrium include parathyroid hormone, vitamin D, fi broblast growth factor-23 (FGF23), and its co-receptor klotho. The fact that this regulatory network is shifted out of balance starting from an early point in disease progression is thought to contribute signifi cantly to one of the most devastating consequences of CKD, uremic medial sclerosis. Characteristic alterations in arterial vessels due to medial sclerosis are considered to be a major contributor to the excessively high cardiovascular disease burden in CKD patients. Hence, there is an urgent need to fi nd viable therapeutic approaches which target its pathogenesis. While several aspects of the aetiology of medial sclerosis remain elusive, there is solid evidence as to the role of phosphate in this process. Excessive phosphate has been shown to induce apoptosis in vascular smooth muscle cells and to stimulate their transdifferentiation towards an osteoblast-like phenotype, whereas it interferes with the acquisition of osteoclast-like properties in vessel-resident monocytes and macrophages and ultimately increases circulating FGF23 levels while suppressing klotho expression.

The Dynamical Analysis of a Prey-Predator Model with a Refuge-Stage Structure Prey Population

We proposed and analyzed a mathematical model dealing with two species of prey-predator system. It is assumed that the prey is a stage structure population consisting of two compartments known as immature prey and mature prey. It has a refuge capability as a defensive property against the predation. The existence, uniqueness, and boundedness of the solution of the proposed model are discussed. All the feasible equilibrium points are determined. The local and global stability analysis of them are investigated. The occurrence of local bifurcation (such as saddle node, transcritical, and pitchfork) near each of the equilibrium points is studied. Finally, numerical simulations are given to support the analytic results.
Flocculation of Fine Particles in Ceramic Wastewater by Using Polymers

The clarification of industrial wastewaters by solid–liquid separation techniques and the removal of suspended particles are the problems of growing environmental consciousness. However, there appears to be very limited number of studies reported in the literature to investigate the flocculation and settling properties of ceramic wastewaters. The efficiency of solid/liquid separation may be greatly improved by the application of synthetic polymeric flocculants, particularly in mineral processing plant where sedimentation, filtration and centrifugation processes are extensively used. In ceramic plants, the water used in ceramic processing is contaminated with suspended quartz, feldspar and associated clay particles, which results in a so-called wastewater problem which have to be dealt with from an environmental point of view. In this study, sedimentation of ultrafine particles from ECE Ceramic Co. (Corum/Turkey) ceramic wastewater sample was investigated using three anionic polymeric flocculants (Superfloc A-130, Superfloc A-100 and Enfloc 330A). The performances of the flocculant in the experimental studies were assessed with the change in the interfaces height during sedimentation resultant. The best performance was obtained Superfloc A-130. At the dose of 60 g/t for A-130, the settling rate was shorter than 60 seconds.
Effect of Fuel Content and Particle Size Distribution of Oxidiser on Ignition of Metal-Based Pyrotechnic Compositions

Influence of boron content in boron-based pyrotechnic composition and particle size distribution of oxidiser, i.e., KNO3 in boron-based pyrotechnic composition is examined by subjecting these to various tests. Study on boron-based pyrotechnic compositions reveals that compositions with 20, 25 and 30 parts by weight of boron are promising igniter compositions wrt their calorimetric values, pressure maximum, ignition delay, etc. However, from sensitivity point of view, the composition with 30 parts of boron is more safe to handle, manufacture and use. From the study of particle size distribution of KNO3 in Mg- based pyrotechnic compositions, it is observed that the composition with wider particle size distribution of oxidiser gives better packing density for their binary miJQ with metal fuel, which in turn gives lower ignition delay and ignition temperature.
BIBO NORM IN SPECTRAL FACTORIZATION AND WIENER FILTERING

This paper characterizes and compares the stability behavior of the spectral factors in the energy norm and in the bounded-input bounded-output (BIBO) norm. These results are used to investigate the energy-/BIBO norm of the Wiener filter and of the corresponding whiteningand estimation filter. Furthermore, the continuity behavior of the spectral factors with respect to errors in the given data is investigated.
Electron spin transport in quantum dots and point contacts

We investigate quantum ﬂuctuations in the non-local resistance of an open quantum dot which is connected to four reservoirs via quantum point contacts. In this four-terminal quantum dot the voltage path can be separated from the current path. We measured non-local resistance ﬂuctuations of several hundreds of Ohms, which have been characterized as a function of bias voltage, gate voltage and perpendicular magnetic ﬁeld. The amplitude of the resistance ﬂuc-tuations is strongly reduced when the coupling between the voltage probes and the dot is enhanced. Along with experimental results, we present a theoretical analysis based on the Landauer-B¨uttiker formalism. While this theory predicts non-local resistance ﬂuctuations of about 20 times larger amplitude than what has been observed, agreement with theory is very good if it is scaled with a factor that accounts for the inﬂuence of orbital dephasing inside the dot. This latter case is in reasonable agreement with an independently determined time scale for orbital dephasing in the dot.
Mixed-Criticality on the AFDX Network: Challenges and Potential Solutions

In this paper, we first assess the most relevant existing solutions enabling mixed-criticality on the AFDX and select the most adequate one. Afterwards, the specification of an extended AFDX, based on the Burst-Limiting Shaper (BLS), is detailed to fulfill the main avionics requirements and challenges. Finally, the preliminary evaluation of such a proposal is conducted through simulations. Results show its ability to guarantee the highest criticality traffic constraints, while limiting its impact on the current AFDX traffic.
THE GAIT SIMULATOR FOR LOWER LIMB EXOPROSTHESES - OVERVIEW AND FIRST MEASUREMENTS FOR COMPARISON OF MICROPROCESSOR CONTROLLED KNEE JOINTS

A test device for lower limb exoprostheses has been developed at the Department of Medical Engineering of the TU Berlin which is able to apply realistic loads to prostheses. Hence, the gait simulator meets the increasing demands on functional and fatigue testing of microprocessor controlled knee joints (MPK). An exemplary comparison of two MPK was performed to prove that known differences in the functional quality of the MPK can also be demonstrated in simulator tests. Significant differences between the MPK could be found. The MPK could not be tested in their full range of function though. To enable comprehensive functional and fatigue testing, the gait simulator has to be modified to achieve higher walking velocities and step lengths.
