Magnetostrictive Properties of Galfenol Alloys Under Compressive Stress

Fe–Ga alloys, in which the α-Fe structure is maintained, are rich sources of high strength, low cost magnetostrictive alloys for transducer and vibration reduction applications. Although the magnetostriction of Fe itself is very low, when a relatively small fraction of the Fe atoms are replaced by Ga, the magnetostriction, (3/2)λ100, increases greatly. Until recently, the highest magnetostriction was found with the replacement of Fe by Al (Alfenol). In this paper, we present our measurements of magnetostriction on Fe1−x Gax , 0.13 ≤ x ≤ 0.24, (Galfenol). With the substitution of 19% Ga for Fe in Fe1−x Gax , a 12-fold increase in magnetostriction to ∼ 400 ppm occurs, even though Ga is non-magnetic. In these alloys, the saturation magnetizations remain high, Ms ∼= 1.7 T, and the Curie temperatures are far above room temperature, TC ∼= 700◦C. In most alloys studied, the magnetostrictions and magnetizations are fully saturated in fields less than 24 kA/m, even under compressive stresses >100 MPa. For x = 0.24 (near Fe3Ga), an anomalous increase in magnetostriction with temperature occurs with a peak magnetostriction above room temperature. Small additions of Ni and Mo to the binary Fe–Ga alloys decrease the room temperature value of λ100.
Roles Of Proteins And Omega-3 / Omega-6 Fatty Acids In Cardiovascular Nutrition

Cardiovascular nutrition is an extremely diverse topic in health and medicine. In the United States alone, there are an increasing number of deaths caused by nutrition-related diseases such as atherosclerosis and high blood pressure. The term "cardiovascular" pertains to the heart and the vascular system the heart uses to help transport nutrients within the body. Blood transports many molecules/compounds that are distributed throughout the body. These compounds include proteins and fatty acids along with various different types of macromolecules. These compounds can be beneficial as well as harmful to one's health, depending on whether he or she has good nutritional habits. The heart and its vessels are so vital that when a CVD (coronary vascular disease) occurs, other organs of the body may be affected as well (Haas, 2004). Most of these kinds of CVDs can actually be traced back to the bottom layer of the organismal hierarchy, which includes molecular activity.
Developments of employment by broad age-groups in Poland in the years 1998–2008. Do their determinants differ?

The latest Eurostat projections show that both population and labour force ageing change employment profiles by age in the European Union countries even in case of an increase in labour force participation and employment (The 2012 Ageing Report). My research question is how basic individual (such as age, education, household position, place of residence) and contextual characteristics (such as the business cycle and the regional labour market situation) influence on employment opportunities in Poland. I test whether the impact of different factors varies with age, which has been categorized to reflect different stages of the life course: youth and young adults (15–29 years old), prime aged (30–54 years old), and older workers (for women: 55–59, for men: 55–64). To answer the research question three types of multilevel logistic models were applied: (a) general models with age as one of the basic determinants, (b) models for each age group for non-agriculture and agriculture. The data used come from the Polish Labour Force Survey (BAEL) of the years 1998–2008 and regional labour market data. The analysis reveals that there are differences in influence of individual and context variables on employment odd ratios between age groups, sex and employment sectors.
Role of nondestructive evaluation in life cycle management

This paper provides an overview of some common NDE methods and several examples for the use of different NDE techniques throughout the life cycle of a product. NDE techniques are being used to help determine material properties, design new implants, extend the service life of aircraft, and help dispose of radioactive waste in a safe manner. It is the opinion of this author and others that the NDE community needs to work more closely with end users in the life cycle of a product to better incorporate NDE techniques. The NDE community needs to highlight the importance of NDE in the entire life-cycle process of a product by showing real costs savings to the manufacturing community.
A Study on the Roles of Designers Co-Evolving with Tools

Humans have always been making tools, creating artefacts with the tools and also using those artefacts as tools. The concept of tools is changing from the expansion of the human body to the expansion of human intelligence. The development of computer technology and the emergence of artificial intelligence raise serious questions about the faculties and roles of humans. The same is true for the faculties and roles of designers who use computers as their main tool in their work. In this paper, the inherent faculties of the human mind, revealed through the Kantian approach, are applied to designers. According to this, it is explained how designers use their own faculties in the world of human artefacts. The co-evolutionary relationship between computers, as evolving tools, and designers is analysed by establishing roles in mutual relations at each phase. The evolution of tools requires designers to take on new roles, which helps designers to better use their faculties.
Editorial: Marginal Jawbone Loss Is Associated With the Onset of Rheumatoid Arthritis and Is Related to the Plasma Level of RANKL

Periodontitis is arguably the most prevalent chronic inflammatory disease of humans, affecting more than 45% of US adults aged 30 years and older (1, 2). The defining feature of periodontitis is chronic inflammation of the tooth supporting tissues leading to the progressive irreversible destruction of periodontal ligament and alveolar bone, resulting in the formation of periodontal pockets and eventually tooth loss if untreated. Host susceptibility is clearly of primary importance and tobacco smoking is a strong environmental risk factor (2). This article is protected by copyright. All rights reserved.
新人賞受賞論文 Using Coefficient-wise Tolerance in Symbolic-Numeric Algorithms for Polynomials

Symbolic-numeric algorithms have been studied by several researchers since early 1990s in the world. With recent studies of approximate factorizations, approximate GCDs and others for numerical or empirical polynomials, we can operate such computations with non-exact coefficients. Those algorithms work well on several Computer Algebra Systems (Mathematica and Maple, for example). Especially on Maple, we can use SNAP (Symbolic Numeric Algorithms for Polynomials) package to compute approximate GCDs. In various implementations of such algorithms, bounding errors on coefficients are provided by polynomial norms (1-norm, 2-norm and∞-norm, for example) in general. Because operating with non-exact coefficients involves computing numerical properties (eg. singular values) and polynomial norms have high affinities for matrix norms and operations. In fact, lots of algorithms for empirical polynomials use the singular value decomposition. However, from a practical point of view, tracking or treating errors as polynomial norms is not applicable as much as floating-point numbers, since for floating-point numbers, we have a few kind of significance arithmetics (interval numbers, for example). In this paper, we review known symbolic numeric algorithms in terms of significance arithmetics, and introduce an absolute irreducibility testing for bivariate polynomials and a relatively prime testing for univariate polynomials. Basically, there is no difference from those original algorithms, but they would be more natural for the people who use significance arithmetics and give more efficient error bounds. We note that this paper is involved with the authors’ presentation at the 14th Workshop of JSSAC (Japan Society for Symbolic and Algebraic Computation), 2005.
Accuracy assessment of the ASTER GDEM and SRTM3 DEM: an example in the Loess Plateau and North China Plain of China

The digital elevation model (DEM) produced by the Shuttle Radar Topographic Mission (SRTM) has provided important fundamental data for topographic analysis in many fields. The recently released global digital elevation model (GDEM) produced by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) has higher spatial resolution and wider coverage than the SRTM3 DEM, and thus may be of more value to researchers. Taking two typical study areas—the Loess Plateau and the North China Plain of China—as an example, this article assesses the accuracy of the SRTM3 DEM and ASTER GDEM by collecting ground control points from topographical maps. It is found that both the SRTM3 DEM and the ASTER GDEM are far more accurate for the North China Plain than for the Loess Plateau. For the Loess Plateau, the accuracy of the ASTER GDEM is similar to that of the SRTM3 DEM; whereas for the North China Plain, it is much worse than that of the SRTM3 DEM. Considering the negative bias of the ASTER GDEM for flat or gentle regions, we improve its accuracy by adding the difference of the mean value between the SRTM3 DEM and ASTER GDEM for the North China Plain; then, the root mean square error (RMSE) of ±7.95 m from the original ASTER GDEM is improved to ±5.26 m, which demonstrates that it is a simple but useful way to improve the accuracy of the ASTER GDEM in flat or gentle regions.
Multivariate statistical analysis of surface water chemistry: A case study of Gharasoo River, Iran

Regional water quality is a hot spot in the environmental sciences for inconsistency of pollutants. In this paper, the surface water quality of the Gharasoo River in western Iran is assessed incorporating multivariate statistical techniques. Parameters like EC, TDS, pH, HCO3 - , Cl - , SO4 2- , Ca 2+ , Mg 2+ and Na + were analyzed. Principal component and factor analysis is showed the parameters generated 3 significant factors, which explained 73.06℅ of the variance in data sets. Factor 1 may be derived from agricultural activities and subsequent release of EC, TDS, SO4 2- and Na + to the water. Factor 2 could be influenced by domestic pollution and explained the deliverance of HCO3 - , Cl - and Mg 2+ into the water. Factor 3 contains hydro-geochemical variable Ca 2+ and pH, originating from mineralization of the geological components of bed sediments and soils of watershed area. Likewise, the clustering analysis generated 3 groups of the stations as the groups had similar characteristic features. Pearson correlation analysis showed significant correlations between HCO3 - and Mg 2+ (0.775), Ca 2+ (0.552) as well as TDS and Na + (0.726). With reference to multivariate statistical analyses it can be concluded that the agricultural, domestic and hydro-geochemical sources are releasing the pollutants into the Gharasoo River water.
Perspectives of Students’ Behavior Towards Mobile Learning (M-learning) in Egypt: an Extension of the UTAUT Model

The rapid development of third-generation (3G) mobile technologies has led to the emergence of a new kind of learning called mobile learning (m-learning). M-learning means the use of mobile devices to access learning materials at anytime and anywhere with the aid of mobile terminals and networks. This paper explores the possibility of applying m-learning for schools in Egypt through a proposed model of acceptance factors that may affect the students’ intentions to adopt m-learning. We use the original model of Unified Theory of Acceptance and Use of Technology (UTAUT) and extended it with three new factors mobility, interactivity, and enjoyment.
Supplemental Feeding Of Birds In Human Settlements Of Western Poland

INTRODUCTION Humans are probably the only species which obtain satisfaction from helping other species, including the feeding of animals. Since the end of the XIX century it has been proposed to feed birds, but only in the recent decades – due to the massive growth of urban populations with an accompanying increase of the urban areas and the synanthropisation and urbanisation of many animal species – bird feeding became more common and can be conducted throughout the year. In supplemental feeding of birds we can distinguish between targeted actions and involuntary actions. Among ornithologists two extreme attitudes are apparent: The suggestion to completely abandon feeding and stop providing nest boxes on the one hand, and the strong propagation of both supplementary feeding and putting up nest boxes to enrich the composition and abundance of birds on the other hand (Berthold and Mohr 2008). The results of several studies indicate that supplemental feeding of birds must follow specified rules (Berthold and Mohr 2008, Graszka-Petrykowski 2008, Szokalski and Wojtatowicz 1989). This view has been commonly accepted now. In cities species inhabiting the built-up and green areas as well as water birds are usually fed (Berthold and Mohr 2008). Despite the fact that the problem of feeding birds has been studied often an in depth in Western Europe and North America, in Poland there are no publications on this topic so far. Supplemental feeding of birds has also biological consequences, increasing survival and breeding success in the next season (Doerr and Silvy 2002, Robb et al. 2008).
Geophysicae Mesoscale aurora within the expansion phase bulge

We present ground-based optical, riometer and magnetometer recordings together with Polar UVI and GOES magnetic field observations of a substorm that occurred over Canada on 24 November 1997. This event involved a clear optical onset followed by poleward motion of the aurora as a signature of an expanding auroral bulge. During the expansion phase, there were three distinct types of meso-scale (10–1000 km) auroral structures embedded in the bulge: at first a series of equatorward moving auroral arcs, followed by a well-defined spiral pair, and finally northsouth directed aurora (a streamer). The spirals occurred several minutes after the onset, and indicate a shear in the fieldaligned current. The north-south aligned aurora that formed about 10 min after the onset suggest bursty bulk flow type flows taking place in the central plasma sheet. Polar UVI observations of the polar cap location indicate that the southward drifting arcs were associated with magnetospheric activity within closed field lines, while the auroral streamer was launched by the bulge reaching the polar cap boundary, i.e. the mid-tail reconnection starting on the open field lines. The riometer data imply high energy electron precipitation in the vicinity of the the poleward moving edge of the auroral bulge, starting at the onset and continuing until the formation of the north-south structure. In this paper, we examine this evolving auroral morphology within the context of substorm theories.
WATER MANAGEMENT ON TOPLICA RIVER IN CHANGING CLIMATE

Marija Ivković 1 Aleksandra Kržič 2 UDK: 556:551.583 DOI:10.14415/konferencijaGFS2017.075 Summary: It is expected that the future climate changes will affect the water balance components in the river catchments, verily causing changes in water regime. This will also have implications on water supply, irrigation systems, renewable energy sources, industrial production as well as whole ecosystems, therefore it is crucial to quantify those changes. IPCC CO2 emission scenarios and used climate models forms different possible future meteorological conditions on Toplica river catchment. Hydrological projections are obtained by forcing the HBV model with the precipitation and temperature data of an atmosphere-ocean coupled regional climate model RCM-SEEVCCC, run with two global climate models, ECHAM5 and its previous version SINTEX-G, under the A1B IPCC/SRES scenario. In addition to these simulations, hydrological simulations run by bias corrected results of the ECHAM5/RCM-SEEVCCC for A2 scenario and CMCC-CM/NMMB model for the new IPCC scenario RCP8.5 are done as well. The impact of different scenarios and their implications on Toplica river water management are presented in this paper.

Talent selection and genetics in sport

Whether the performance demonstrated by talented sportsmen is hereditary or acquired later has become subject of research for physical education and sport scientists from past to present. However, training science and trainers wonder how far can reach the higher performance limits emerging as a result of talents available in sportsmen. Studies carried out suggested that the concept of higher performance comes true with aggregated environmental and genetic factors. The aim of our study is to discuss the role played by genetics on the differences in performance of sportsmen and selection of sportive talent.

Remarks on a question of Skolem about the integer solutions of x 1 x 2 − x 3 x

He pointed out that it seemed unlikely that all the integral solutions could be obtained from a fixed polynomial parametrization of (1) by letting the variables run through all integers (actually Skolem considered the more general equation det(xij) = 1, 1 ≤ i, j ≤ n). Observe (cf. [Sz]) that we can find infinitely many polynomial solutions of (1) with coefficients in Z by considering the generic continued fractions a0+ 1 a1+ . 1 an where the ai are variables. As is well known, we can write the value of such fraction as pn/qn, where pn, qn are polynomials in the ai’s satisfying pn+1qn−qn+1pn = (−1)n. However, no such formula produces all integral solutions of x1x2 − x3x4 = 1 by letting the ai run through all integers: in fact, it can be easily shown by induction on n that, if the ai ∈ Z, the rational number pn/qn has a continued fraction expansion with a number of terms bounded by a function of n only. (These references and remarks were pointed out to me by A. Schinzel.) In the present note we shall prove Skolem’s expectation under the assumption (apparently very strong, but see Remarks 3, 4 and Example 1 below) that the polynomials appearing in the parametrization depend on three variables only (i.e. like the dimension of the quadric defined by (1)); actually, we shall argue over any number field k, with ring of integers Ok. We have the following
Interactive comment on “Combining a pollen synthesis and climate simulations for spatial reconstructions of European climate using Bayesian modelling” by Nils Weitzel et al

Probabilistic spatial reconstructions of past climate states are valuable to quantitatively study the climate system under different forcing conditions because they combine the information contained in a proxy synthesis in a comprehensible product. Unfortunately, they are subject to a complex uncertainty structure due to complicated proxy-climate relations and sparse data, which makes interpolation between samples difficult. Bayesian hierarchical models feature promising properties to handle these issues like the possibility to include multiple sources of information and to quantify uncertainties in a statistically 5

The contrasting influence of short-term hypoxia on the hydraulic properties of cells and roots of wheat and lupin

Little is known about water flow across intact root cells and roots in response to hypoxia. Responses may be rapid if regulated by aquaporin activity, but only if water crosses membranes. We measured the transport properties of roots and cortical cells of three important crop species in response to hypoxia (0.05 mol O2 m–3): wheat (Triticum aestivum L.), narrow-leafed lupin (Lupinus angustifolius L.) and yellow lupin (Lupinus luteus L.). Hypoxia influenced solute transport within minutes of exposure as indicated by increases in root pressure (Pr) and decreases in turgor pressure (Pc), but these effects were only significant in lupins. Re-aeration returned Pr to original levels in yellow lupin, but in narrow-leafed lupin, Pr declined to zero or lower values without recovery even when re-aerated. Hypoxia inhibited hydraulic conductivity of root cortical cells (Lpc) in all three species, but only inhibited hydraulic conductivity of roots (Lpr) in wheat, indicating different pathways for radial water flow across lupin and wheat roots. The inhibition of Lpr of wheat depended on the length of the root, and inhibition of Lpc in the endodermis could account for the changes in Lpr. During re-aeration, aquaporin activity increased in wheat roots causing an overshoot in Lpr. The results of this study demonstrate that the roots of these species not only vary in hydraulic properties but also vary in their sensitivity to the same external O2 concentration.
