Submerged macrophyte biomass distribution in the shallow saline lake Fuente de Piedra (Spain) as function of environmental variables

Aquatic macrophyte biomass, diaspore bank distribution and their relationship to spatial variability of depth, nutrients (nitrite, nitrate, ammonium and soluble reactive phosphorus) as well as sediment granulometry in an athalassohaline lake have been studied during one wet hydrological year. The results indicate that species growing in the lake show different spatial distribution patterns throughout the lake. Indirect gradient analysis (canonical analysis) results showed a first axis defined as a function of Ulva flexuosa Wulfen biomass which is, in turn, positively correlated with interstitial ammonium and Soluble Reactive Phosphorus (SRP). The second axis was mainly established due to Lamprothamnium papulosum (Wallr.) J. Groves biomass which correlated positively to depth and negatively to interstitial ammonium and SRP. These results revealed a NESW eutrophic gradient allowing the U. Flexuosa biomass proliferation. This phenomenon could increase the shadow effect over the rest of the macrophytes inhabiting this shallow lake. Moreover, the eutrophic harmful effect on the macrophyte physiology and over the diaspore bank could have important consequences in the survival of such important populations. The results reported in this study show the need for studies as the base to select sampling points for monitoring this wetland.
Pre-Service Computer Teachers’ Tendencies Towards the Use of Mobile Technologies: A Technology Acceptance Model Perspective

Abstract Drawing on the Technology Acceptance Model (TAM), this exploratory study examines the preservice teachers’ adoption of mobile technologies through the factors of current use, instructional use and future use in their teaching practices. Participants were 466 pre-service computer teachers enrolled at a public university in Turkey. A questionnaire developed by the researchers was used to collect data. Results indicated that the current use and instructional use factors had a strong positive correlation and also there was a similar correlation with the factor of future use and current use. Relationships between current, instructional, and future use of mobile technologies explained within the context of perceived usefulness, ease of use, and behavioural intention constructs of the TAM.
Molecular modelling study of the 3D structure of the biglycan core protein, using homology modelling techniques

Herein we report the establishment of the 3D structure of the biglycan core protein, using conventional homology molecular modelling techniques. The 3D model has been structurally optimised via molecular dynamics. It was found that the final model of biglycan resembles in structure its template protein bearing a set of distinct parallel β-sheet structure patterns. The biglycan model bears a very hydrophobic amino acid region towards its inner cavity that acquires an arc-like structure. The external domain of the biglycan model is made up of hydrophilic residues that are exposed to the water solvent. It is those hydrophilic residues that are responsible for their interaction with polysaccharide polymers. Overall comparison of the model of biglycan to the recently determined x-ray structure of the same protein returns a very low Root Mean Square Deviation (RMSD), which confirms the viability of the model and its reliability as a platform for the study biglycan interactions.
Edge effects on ground-dwelling beetles (carabidae and Staphylinidae) in oak forest-forest edge-grassland habitats in Hungary

Forest edges are essential to the maintenance of biodiversity at the landscape level. according to the edge effect hypothesis, diversity is higher in an edge than in adjacent areas. We tested the edge effect hypothesis for carabids and staphylinids in an oak forest- forest edge-grassland complex in the Hajdusag Landscape Protection area (Hungary). The habitat types were as follows: (1) a closed oak forest with shrubs and herbaceous plants, (2) a forest edge with extensive ground vegetation and shrub cover and (3) grassland with dense herbaceous vegetation. We collected data from 60 pitfall traps (2 spatial replicates × 3 habitats × 10 traps). The gLM results showed that the species richness of carabids was higher at the edge of the forest than in the grassland and forest interior; the number of carabid individuals was highest in the grassland. The number of staphylinids and their species richness were significantly lower in the grassland than in the forest edge and interior. The results of principal coordinates analysis showed that the assemblages of both taxa in the forest edge and interior were separated from the assemblage in the grassland area. There were significant characteristic species for the edge habitat, as revealed by the IndVal (indicator species analysis) method. our findings suggest that forest edges play a vital role in the maintenance of the diversity of carabid and staphylinid assemblages.
Catchment-scale groundwater recharge and vegetation water use efficiency

Abstract. Precipitation undergoes a two-step partitioning when it falls on the land surface. At the land surface and in the shallow subsurface, rainfall or snowmelt can either runoff as infiltration/saturation excess or quick subsurface flow. The rest will be stored temporarily in the root zone. From the root zone, water can leave the catchment as evapotranspiration or percolate further and recharge deep storage. It was recently shown that an index of vegetation water use efficiency, the Horton index (HI), could predict deep storage dynamics. Here we test this finding using 247 MOPEX catchments across the conterminous US. Our results show that the observed HI is indeed a reliable predictor of deep storage dynamics. We also find that the HI can reliably predict the long-term average recharge rate. Our results compare favorably with estimates of average recharge rates from the US Geological Survey. Previous research has shown that HI can be estimated based on aridity index, mean slope and mean elevation of a catchment (Voepel et al., 2011). We recalibrated Voepel’s model and used it to predict the HI for our catchments. We then used these predicted values of the HI to estimate average recharge rates for our catchments, and compared them with those estimated from observed HI. We find that the accuracies of our predictions based on observed and predicted HI are similar. This provides a novel estimation method of catchment-scale long-term average recharge rates based on simple catchment characteristics, such as climate and topography, and free of discharge measurements.
The Arctic shelf regions as a source of freshwater and brine-enriched waters as revealed from stable oxygen isotopes

The water masses of the Arctic Ocean shelf regions are significantly influenced by river water and sea-ice processes. Since river water is highly depleted in ∂18O relative to marine waters as well as to sea-ice, the ∂18O composition and salinity of a water sample can be used to separate the different freshwater water sources. In this paper the distributions of river water, sea-ice melt water or sea-ice formation are discussed for the Kara, Laptev and Beaufort shelves based on ∂18O and salinity data. Depending on the average depth the observed fields of salinity and ∂18O values are different for each region. But comparing the overall ∂18O and salinity correlations reveals a remarkable similarity for these three Arctic shelf regions as similar local bottom-water masses are formed by sea-ice processes. Remnants of these seaice derived bottom water masses are found on all shelves during summer at a salinity of about 30. Investigations at the shelf break of the Kara Sea and Laptev Sea show that river water as well as brine waters are exported to the Arctic Ocean halocline. This export shows inter-annual variability in correlation with wind forcing during summer.
Sentiment Analysis: A Survey

Traditional approaches to sentiment classification rely on lexical features, syntax-based features or a combination of the two. Word senses used as features show promise, we also examine the possibility of using similarity metrics defined on WordNet to address the problem of not finding a sense in the training corpus. Different methods of sentiment classification are also described in it. Thus is provides a broad way of analyzing the methods and making conclusion provided by these methods. Sentiment Analysis is a Natural Language Processing and Information Extraction task that aims to obtain writer’s feelings expressed in positive or negative comments, by analyzing a large numbers of documents. Generally speaking, sentiment analysis aims to determine the attitude of a speaker or writer with respect to some topic of a document. In recent years, the exponential increase in the Internet usage and exchange of public opinion is the driving force behind Sentiment Analysis today.
School Careers of Students from Ethnic Minorities in the Netherlands.

This study investigated the influences that are related to a successful school career for students in the Netherlands and compared ethnic minority students with students from a Dutch background. Data were drawn from a study on Dutch educational policy for 5,311 students in elementary and secondary school, 24.5% of whom were ethnic minorities largely from Surinamese, Turkish, or Moroccan backgrounds. Students of Dutch background clearly had higher levels of academic achievement, and their parents had higher socioeconomic status and more cultural capital. Findings suggest that it is better to study cultural capital than socioeconomic status alone when considering the academic achievement of ethnic minority students.

Forty-two

This article explores the meaning and context of intellectual capital (IC) numbers to help break free from the domination of IC “accountingisation” . Offering a personal and reflective narrative about IC numbers, I first discuss what numbers mean by exploring the way we think about the number 42. This discussion is followed by two empirical sections examining the meaning and context of a common IC measure, employee turnover rates. Measuring any IC element is problematic from an IC accounting perspective because of the unique context in which each organization operates. The comparability of a number from one organization and one period with another is nearly impossible. The article is original because it takes a thought-provoking narrative journey into the use and meaning of applying IC numbers. It is a personal reflection on the implications of considering the meaning of numbers for IC practice, IC education and research, and IC’s future. It is particularly topical in light of the inclusion of IC in the recent Integrated Reporting () Guidelines.
Characteristics of 2-D Electrical Resistivity Imaging Survey for Soil

The present work is aimed to show the efficiency of 2-D Electrical Resistivity Imaging (ERI) in probing the subsurface soil for site investigation, in addition to highlight some capabilities and characteristics of the sections acquired by 2D-ERI survey. In the field survey, where the University of Technology site is chosen for such investigation, ERI technique has been used implementing three common arrangements (Wenner, Wenner-Sclumberger and dipole-dipole). Different resolving powers have been obtained for the used arrays. Wenner-Schlumberger array gives moderate number of possible measurements and has a median depth of investigation of about 10% larger than that for the Wenner array. It is moderately sensitive to both horizontal and vertical structures, thus it might be a good compromise between the Wenner and the dipole-dipole arrays. Good agreements have been obtained between the stratigraphic columns of the site with the inversion models using the different arrays. The distribution of resistivity of the inversion models for the study site reflects the highly inhomogeneous subsurface soil with a wide variation of soil resistivity at different depths.
Testing for structural change in spatial regions at unknown positions

We propose a fluctuation-type procedure for detecting breaks in spatial regions. While such tests are common in the context of time series, it is not a priori clear how to apply them to spatial data as there is no natural order of the observations. We demonstrate how this order can be constructed from a spatial autoregressive model. Once such an order is derived, standard time series results apply and break points can be consistently identified.
The retrograde orbit of the HAT-P-6b exoplanet

We observed with the SOPHIE spectrograph (OHP, France) the transit of the HAT-P-6b exoplanet across its host star. The resulting stellar radial velocities display the Rossiter-McLaughlin anomaly and reveal a retrograde orbit: the planetary orbital spin and the stellar rotational spin point towards approximately opposite directions. A fit to the anomaly measures a sky-projected angle lambda = 166 +/- 10 degrees between these two spin axes. All seven known retrograde planets are hot jupiters with masses M_p 4 M_Jup) are prograde but misaligned. Different mechanisms may therefore be responsible for planetary obliquities above and below ~3.5 M_Jup.
A ug 2 01 5 The deceleration parameter in ‘ tilted ’ Friedmann universes

Large-scale peculiar motions are believed to reflect the local inhomogeneity and anisotropy of the universe, triggered by the ongoing process of structure formation. As a result, realistic observers do not follow the smooth Hubble flow but have a peculiar, ‘tilt’, velocity relative to it. Our Local Group of galaxies, in particular, moves with respect to the universal expansion at a speed of roughly 600 km/sec. Relative motion effects are known to interfere with the observations and their interpretation. The strong dipolar anisotropy seen in the Cosmic Microwave Background, for example, is not treated as a sign of real universal anisotropy, but as a mere artifact of our peculiar motion relative to the Hubble flow. With these in mind, we look into the implications of large-scale bulk motions for the kinematics of their associated observers, by adopting a ‘tilted’ Friedmann model. Our aim is to examine whether the deceleration parameter measured in the rest-frame of the bulk flow can differ from that of the actual universe due to relative-motion effects alone. We find that there is a difference, which depends on the speed as well as the scale of the bulk motion. The faster and the smaller the drifting domain, the larger the difference. In principle, this allows relatively slow peculiar velocities to have a disproportionately strong effect on the value of the deceleration parameter measured by observers within bulk flows of, say, few hundred megaparsecs. In fact, under certain circumstances, it is even possible to change the sign of the deceleration parameter. It goes without saying that all these effects vanish identically in the Hubble frame, which makes then an illusion and mere artifact of the observers’ relative motion.
Milk yield and blood urea nitrogen in crossbred cows grazing Leucaena leucocephala in a silvopastoral system in the Mexican tropics

The aim of the study was to assess milk yields, estimate the intake of crude protein (CP) and determine the concentrations of blood urea nitrogen (BUN) in early post-partum crossbred cows grazing irrigated Leucaena leucocephala (leucaena) in a silvopastoral system relative to those in an irrigated grass monoculture. Twenty-four multiparous cows were randomly allotted at calving on the basis of previous milk yields to 2 grazing treatments: grass monoculture system (MS) of Cynodon nlemfuensis (n=12); and an intensive silvopastoral system (ISS) composed of leucaena and C. nlemfuensis (n=12). Cows were supplemented with sorghum grain (ISS) or a conventional concentrate (MS) during milking to ensure availability of metabolizable energy (ME) and CP required for milk production. Mean estimated intake of leucaena was 5.1±1.3 kg DM/d and estimated CP intakes were 1,479±3.3 and 1,258±3.3 g/d for ISS and MS, respectively (P>0.05), while estimated intakes of ME were 161±1.3 and 131±1.4 MJ/d for ISS and MS, respectively (P 0.05). Concentrations of BUN were 19.1 mg/dL for cows in ISS and 15.3 mg/dL for cows in MS (P<0.05). We conclude that intake of leucaena and sorghum grain in an irrigated silvopastoral system was sufficient to substitute for expensive concentrate in the diets of lactating cows grazing irrigated grass monoculture. However, the higher levels of BUN found in ISS suggest a lower efficiency of N utilization in this treatment. Restricting consumption of leucaena might be a means of improving efficiency of its use and this warrants investigation.

Coxeter and the Artists: Two-Way Inspiration, Part 2

H.S. M. Coxeter's delight in geometric form was the catalyst for fruitful two-way interactions with artists, sculptors, and model-makers. His publications and personal encouragement inspired them to create breathtaking expressions of the power and beauty of geometry. The inspiration was often reciprocal: the artists' expressions, frequently guided by their unique intuition, sparked Coxeter's geometric curiosity and often provided new mathematical insight.
Short-term persistence and mutual fund characteristics

Outperforming mutual funds continue to display quarterly momentum effects during the 1998-2007 period. Further analyses on fund characteristics demonstrate that the relative price of funds (to earnings and book value) is the key indicator of the performance persistence. Specifically, cheaper winner funds (low P/E or P/B ratios) are more persistent in their performances. The double-sort momentum strategies based on these characteristics enhance the momentum returns by around 0.88 per cent to 1.44 per cent per quarter compared to traditional single-sort strategies.
ON THE STRUCTURE AND STABILITY OF MAGNETIC TOWER JETS

Modern theoretical models of astrophysical jets combine accretion, rotation, and magnetic fields to launch and collimate supersonic flows from a central source. Near the source, magnetic field strengths must be large enough to collimate the jet requiring that the Poynting flux exceeds the kinetic energy flux. The extent to which the Poynting flux dominates kinetic energy flux at large distances from the engine distinguishes two classes of models. In magneto-centrifugal launch models, magnetic fields dominate only at scales ≲ 100 engine radii, after which the jets become hydrodynamically dominated (HD). By contrast, in Poynting flux dominated (PFD) magnetic tower models, the field dominates even out to much larger scales. To compare the large distance propagation differences of these two paradigms, we perform three-dimensional ideal magnetohydrodynamic adaptive mesh refinement simulations of both HD and PFD stellar jets formed via the same energy flux. We also compare how thermal energy losses and rotation of the jet base affects the stability in these jets. For the conditions described, we show that PFD and HD exhibit observationally distinguishable features: PFD jets are lighter, slower, and less stable than HD jets. Unlike HD jets, PFD jets develop current-driven instabilities that are exacerbated as cooling and rotation increase, resulting in jets that are clumpier than those in the HD limit. Our PFD jet simulations also resemble the magnetic towers that have been recently created in laboratory astrophysical jet experiments.
Immediate and mid-term effects of elastic taping on gymnast’s postural control performance during a handstand

Background: The study explored whether three different applications of an elastic tape on the forearms of healthy, active gymnasts influence their postural control performance during a handstand immediately and 48 hours after application. Material/Methods: 24 gymnasts were randomly assigned to three groups: group 1 – elastic tape application at a gymnast’s wrist joints, group 2 – elastic tape application at a gymnast’s forearm muscles, and group 3 – a combination of groups 1 and 2. The gymnast’s center of pressure was measured with a mobile balance platform, indicating postural control performance during a handstand. Results: The gymnast’s postural control performance during a handstand is affected depending on the elastic tape application and the time span the application is in situ. Elastic tape application on a gymnast’s wrist joints reveals a performance increase immediately and 48 hours after application. Elastic tape application on a gymnast’s forearm muscles increases performance when applied for 48 hours. Combined elastic tape application does not additionally affect gymnast’s postural control performance. Conclusions: Elastic tape applications can increase postural control performance during a handstand. Furthermore, it is supposed that mechano-sensory stimulation, improved attention and awareness due to elastic tape application and the belief in its effectiveness may be moderating mechanisms of this effect.
For always taking the time to answer my questions and especially for being very good and knowledgeable , and able to explain things in an easy manner to others

Optically levitated nano spheres show great prospects for the goal of preparing mesoscopic objects in their quantum mechanical ground state (Chang et al., 2010). This requires to trap the particles at pressures below 10−7mBar, and hence sophisticated loading mechanisms that comply with an ultra high vacuum (UHV) environment. In (Grass, 2013) it is shown, that hollow core photonic crystal fibers (HCPCF) do not only support the trapping and transport of nano particles, but can also be used to bridge pressure differences of nine orders of magnitude, thereby making them a promising candidate for an UHV compatible loading mechanism. The work in this thesis continues the efforts in that direction. So far the HCPCF loading scheme is limited by the fact, that due to up to now unknown reasons, the particles are lost during the evacuation at pressures around 1mBar. Active cooling of the particle motion based on parametric feedback, is known to be a working countermeasure (Gieseler et al., 2012; Li et al., 2011) and is what we set out to implement in our loading scheme. En route to this, we successfully demonstrate a three dimensional position readout of the particle motion inside the HCPCF, that is based on higher order guided modes. It turns out, that these modes can also have an interesting effect on the trapping potential, which is experimentally verified. In addition we discuss preliminary results on feedback cooling in one of the radial dimensions.
