Quali-quantitative characterization of organic matter in urbanized drainage basins as a basis for the application of Water Resources Management Instruments

ABSTRACT The challenge imposed by law no. 9433/97 to establish mechanisms for the recovery of bodies of water led to a dynamic of research that could guarantee not only an adequate understanding of the management instruments but also the technical basis for their application. In this research, emphasis was placed on understanding the dynamics of organic matter (OM) in a drainage basin heavily influenced by anthropogenic activities, through the analysis and interpretation of qualitative and quantitative information. The case study was the Iguacu River basin, from its headwaters in the Metropolitan Region of Curitiba (MRC) to the municipality of Uniao da Vitoria . The results obtained showed a large deposition of labile OM in the MRC coming probably from domestic effluents, with consequent DO depletion and water quality degradation. However, after the more urbanized region, there is a reduction in the concentration of OM and the indication of the predominance of pedogenic material, suggesting that in addition to the dilution effect, there is less input of anthropogenic effluents in this region, which results in an improvement in water quality, represented mainly by the recovery of the DO concentration. The combined use of quantitative data and UV-visible spectroscopy was fundamental to comprehend the variation in the characteristics of OM and its sources along the studied section.
Hubungan antara pendekatan pengajaran guru dengan pendekatan pembelajaran pelajar mata pelajaran kimia tingkatan empat

Model Pembelajaran 3P menggambarkan bilik darjah sebagai satu sistem interaktif antara presage, process dan product. Maka, model ini menjadi landasan untuk penyelidik mengkaji faktor presage, iaitu pendekatan pengajaran guru dengan faktor process, iaitu pendekatan pembelajaran mendalam (PM) dan pembelajaran permukaan (PP) pelajar-pelajar tingkatan empat dalam mata pelajaran kimia. Sejumlah 30 orang guru dari 28 buah sekolah dan 400 orang pelajar dari 10 buah sekolah di daerah Pasir Gudang telah diambil sebagai sampel kajian. Approaches to Teaching Inventory (ATI) dan Revised Two-Factor Study Process Questionnaire (RSPQ- 2F) digunakan sebagai instrumen kajian. Data mentah dianalisis menggunakan perisian SPSS for Windows Version 10.0. Kaedah statistik iaitu Ujian-t digunakan untuk menentukan kecenderungan pendekatan pengajaran guru dan pendekatan pembelajaran pelajar. Selain itu, analisis korelasi linear Pearson â€˜râ€™ digunakan untuk menentukan pertalian antara pendekatan pengajaran guru dengan pendekatan pembelajaran pelajar. ANOVA satu arah pula digunakan untuk menentukan kesan pengalaman mengajar guru terhadap pendekatan pengajaran. Hasil analisis menunjukkan bahawa guru kimia lebih cenderung mengaplikasikan pendekatan penyampaian maklumat/ berpusatkan guru (PMBG) daripada pendekatan perubahan konsep/ berpusatkan pelajar (PKBP). Manakala pelajar lebih cenderung menggunakan PM daripada PP dalam pembelajaran kimia. Analisis menunjukkan pertalian yang rendah antara pendekatan PMBG dengan PM dan antara PMBG dengan PP. Namun kedua-dua hubungan ini adalah tidak signifikan. Hasil ANOVA menunjukkan tiada perbezaan yang signifikan bagi pendekatan PMBG dan PKBP dalam ketiga-tiga kategori pengalaman mengajar mata pelajaran kimia.
Municipal Sustainability Influence by European Union Investment Programs on the Portuguese Local Government

The assessment of the impact of European Structural and Investment Funds (ESIF) on Portuguese local government and which factors determine it is important given the magnitude of funds involved. As part of this larger question, this paper considers whether the holistic sustainability of local authorities—as measured by a Council Sustainability Index—can influence the impact of ESIF on the performance of Portuguese councils and which factors best explain these performance differences. Using a geometric distance function jointly with the Hicks-Moorsteen index, we investigate and present a conclusion on the differential impact of ESIF on sustainable and non-sustainable Portuguese councils over the period 2000 to 2014. Our findings also suggest that ESIF should continue fostering economic and social development at the local level regardless of council size or regional location since overall development will flow from this economic and social structural adjustment strategy.
Size characterisation of Au nanoparticles by ICP-MS coupling techniques

In modern nanotechnology the properties of nanoparticles (NPs) in different application fields is mainly dependent on their size and their size distribution. This paper aims to develop a reliable method for the size characterisation of Au NPs. Basing on the combination of two different separation techniques (liquid chromatography and gel electrophoresis), coupled on-line to inductively coupled plasma-mass spectrometry (ICP-MS), we study the separation of Au NP standards. Separations by liquid chromatography show size dependent retention behaviour with good reproducibility (RSD < 1%). The results are compared with complementary methods like dynamic light scattering (DLS) and transmission electron microscopy (TEM) and show good agreement. Furthermore, the on-line coupling of gel electrophoresis and ICP-MS results in a distinct peak tailing for the analysis of these NPs, which is found to be related to the chemical structure of the NP’s surface. It can be demonstrated that NPs with a covalently bound surface do behave in a different way.
Universal Spin Transport and Quantum Bounds for Unitary Fermions

We review recent advances in experimental and theoretical understanding of spin transport in strongly interacting Fermi gases. The central new phenomenon is the observation of a lower bound on the (bare) spin diffusivity in the strongly interacting regime. Transport bounds are of broad interest for the condensed matter community, with a conceptual similarity to observed bounds in shear viscosity and charge conductivity. We discuss the formalism of spin hydrodynamics, how dynamics are parameterized by transport coefficients, the effect of confinement, the role of scale invariance, the quasiparticle picture, and quantum critical transport. We conclude by highlighting open questions, such as precise theoretical bounds, relevance to other phases of matter, and extensions to lattice systems.

There are several methods thathave been developed to increase the efficiency of ICM cell isolation as well as improve the ES cells derivation rate. Inconventional ICM isolation methods, the methods currently in use destroy trophectoderm cells of blastocyst stageembryos in order to release the ICM cell clumps. These conventional methods are considered embryo destructionmethods as the embryos will be unable to survive after ICM is removed. Recently, an alternative method wasreported using single biopsied blastomeres of earlier stage embryos as a source of ES cells. This novel methodprovides a new, ethically positive option that avoids destroying the embryos. This brief review of the techniquesinvolved in ICM isolation and ES cells establishment, along with methodological comparisons, outlines thedevelopment of each technique, which may be used as a resource for choosing a suitable procedure for futureexperiments.

Development of the Mission Skills Assessment and Evidence of Its Reliability and Internal Structure

The Mission Skills Assessment (MSA) is an online assessment that targets 6 noncognitive constructs: creativity, curiosity, ethics, resilience, teamwork, and time management. Each construct is measured by means of a student self-report scale, a student alternative scale (e.g., situational judgment test), and a teacher report scale. Use of the MSA provides schools with the opportunity to examine and monitor development of noncognitive skills in their students from Grade 6 to Grade 8. The use of the MSA has facilitated changes to curricula and more targeted instruction. The MSA scales exhibited meaningful relationships with standardized test scores and absenteeism, suggesting that these constructs play an important role in student behaviors and academic performance. This report presents reliability and factor analysis evidence for the student self-report and teacher report scales of the MSA to highlight its ability to measure the 6 constructs.
Comparative Study of Metaheuristics for the Curve-Fitting Problem: Modeling Neurotransmitter Diffusion and Synaptic Receptor Activation

Synapses are key elements in the information transmission in the nervous system. Among the different approaches to study them, the use of computational simulations is identified as the most promising technique. Simulations, however, do not provide generalized models of the underlying biochemical phenomena, but a set of observations, or time-series curves, displaying the behavior of the synapse in the scenario represented. Finding a general model of these curves, like a set of mathematical equations, could be an achievement in the study of synaptic behavior. In this paper, we propose an exploratory analysis in which selected curve models are proposed, and state-of-the-art metaheuristics are used and compared to fit the free coefficients of these curves to the data obtained from simulations. Experimental results demonstrate that several models can fit these data, though a deeper analysis from a biological perspective reveals that some are better suited for this purpose, as they represent more accurately the biological process. Based on the results of this analysis, we propose a set of mathematical equations and a methodology, adequate for modeling several aspects of biochemical synaptic behavior.
Variable selection and forecasting via automated methods for linear models: LASSO/adaLASSO and Autometrics

Abstract In this article we compare two approaches of model selection methods for linear regression models: classical approach—Autometrics (automatic general-to-specific selection)—and statistical learning—LASSO (-norm regularization) and adaLASSO (adaptive LASSO). In a simulation experiment, considering a simple setup with orthogonal candidate variables and independent data, we compare the performance of the methods concerning predictive power (out-of-sample forecast), selection of the correct model (variable selection) and parameter estimation. The case where the number of candidate variables exceeds the number of observation is considered as well. Finally, in an application using genomic data from a high-throughput experiment we compare the predictive power of the methods to predict epidermal thickness in psoriatic patients, and we perform a simulation experiment with correlated variables, based on the application.
Determinants Of User Satisfaction With Mobile Applications: Case Of Facebook As A Mobile App In Turkey

A mobile app is a computer (software) program designed to run on smartphones, tablet computers and other mobile devices (Wikipedia). The increased use of mobile devices and mobile Internet has led to an explosion of the development and download of mobile applications. Businesses started competing to have a mobile application to gain competitive advantage or stay competitive. But despite the success of some, the majority of mobile applications fails outright or is not as successful as expected. So this study aims to define the factors that affect user satisfaction as a success measure of mobile applications. I/S Success Model is used as a basis for this study, and the model is expanded with the constructs related to flow. The research framework includes seven antecedents (system reliability and design, perceived ease of use, content usefulness, content quality, focused attention, perceived enjoyment, and flow) of user satisfaction that were derived from existing information systems, m-commerce and applications literature. The structural equation modeling (SEM) method was applied to evaluate the hypothesized relationships among the constructs in the theoretical model developed. The results of the study showed that system quality and information quality are important determinants of user satisfaction, but flow does not have a direct influence on user satisfaction. The most striking finding of this study is that perceived enjoyment is a significant determinant of satisfaction with mobile applications. Based on the findings, companies involved in m-commerce should focus on not only to improve the usefulness or quality of the system but also the design features of the applications that enhance enjoyment and the experience must also be considered carefully.
Expenditure trends in US advertising : long-term effects and structural changes with new media introductions

Historically US Media channels have competed to attract advertising expenditure from marketing. This has been a fierce battle, where, every few years, incumbents have been shattered by the introduction of a new media such as TV, Yellow Pages, Cable and the Internet. In this paper we will analyze and discuss the dynamic trend in advertising expenditure for ten different advertising media channels in the U.S., by estimating the long-term equilibrium between these time series, and their equilibrium cross-elasticities. We will also analyze how they are related to the business cycle, both at the aggregated level and specifically for each media. To this end, it is crucial to consider simultaneously the impact of new media introductions over the incumbents, estimating the potential effects of structural changes. Both, the introduction effects and the long-term equilibrium relationship between two media can be very different. In particular, we will study the influence of the Internet
Foraminiferal assemblages in acid residues from the "Císařská rokle" Gorge at Srbsko (the Lower/Middle Devonian boundary interval, Barrandian area) and their paleoenvironmental significance

Thirteen foraminiferal taxa in acid residues were described from the "Cisařska rokle" Gorge at Srbsko. Foraminifers were recorded only in the nodular Třebotov Limestone and their assemblages are rare and low-diversified. Assemblages dominated by Thurammina diforamens Ireland occur in the lowermost part of the Třebotov Limestone with shale intercalations. Assemblages with Tolypammina div. sp. occur in the lowermost and uppermost part of nodular limestones without shale intercalations. Among Tolypammina div. sp. , morphotypes with whole attached tests prevailed, which may indi- cate higher-energy environment. Similarly to other sections from this time interval, assemblages dominated by Ammodiscus ex gr. incertus Orbigny pre- vailed in the middle part of the Třebotov Limestone Bimodal size distribution of their tests corresponds probably to megalo- and microspheric forms.

Headwater sediment dynamics in a debris flow catchment constrained by high-resolution topographic surveys

Abstract. Debris flows have been recognized to be linked to the amounts of material temporarily stored in torrent channels. Hence, sediment supply and storage changes from low-order channels of the Manival catchment, a small tributary valley with an active torrent system located exclusively in sedimentary rocks of the Chartreuse Massif (French Alps), were surveyed periodically for 16 months using terrestrial laser scanning (TLS) to study the coupling between sediment dynamics and torrent responses in terms of debris flow events, which occurred twice during the monitoring period. Sediment transfer in the main torrent was monitored with cross-section surveys. Sediment budgets were generated seasonally using sequential TLS data differencing and morphological extrapolations. Debris production depends strongly on rockfall occurring during the winter–early spring season, following a power law distribution for volumes of rockfall events above 0.1 m3, while hillslope sediment reworking dominates debris recharge in spring and autumn, which shows effective hillslope–channel coupling. The occurrence of both debris flow events that occurred during the monitoring was linked to recharge from previous debris pulses coming from the hillside and from bedload transfer. Headwater debris sources display an ambiguous behaviour in sediment transfer: low geomorphic activity occurred in the production zone, despite rainstorms inducing debris flows in the torrent; still, a general reactivation of sediment transport in headwater channels was observed in autumn without new debris supply, suggesting that the stored debris was not exhausted. The seasonal cycle of sediment yield seems to depend not only on debris supply and runoff (flow capacity) but also on geomorphic conditions that destabilize remnant debris stocks. This study shows that monitoring the changes within a torrent's in-channel storage and its debris supply can improve knowledge on recharge thresholds leading to debris flow.
A COMPARISON OF THE EFFECTS OF THREE GM CORN ON MAMMALIAN HEALTH

We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603, MON 810, MON 863), which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and MON 863 are engineered to synthesize two different Bt toxins used as insecticides. Approximately 60 different biochemical parameters were classified per organ and measured in serum and urine after 5 and 14 weeks of feeding. GM maize-fed rats were compared first to their respective isogenic or parental non-GM equivalent control groups. This was followed by comparison to six reference groups, which had consumed various other non-GM maize varieties. We applied nonparametric methods, including multiple pairwise comparisons with a False Discovery Rate approach. Principal Component Analysis allowed the investigation of scattering of different factors (sex, weeks of feeding, diet, dose and group). Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn. In addition, unintended direct or indirect metabolic consequences of the genetic modification cannot be excluded.
NEAR-SYNONYMY ANALYSIS OF THE DESCRIPTIVE ADJECTIVES BEAUTIFUL IN ENGLISH AND LEP,-A,-O IN SERBIAN IN CONTRAST

This paper focuses on the specific method of near-synonymy analysis in English and Serbian. Currently, this issue has been extensively researched in English through lexical choice analysis while using various mathematical equations to distinguish the proximity of meaning among the selected synonymous expressions. In this research paper, near synonyms are analysed through the most frequent collocational framework of the node word and the matching co-occurrences of its suggested near synonyms in Serbian as well as in English. Furthermore, this method is proposed as a useful means of selecting near synonyms within the forthcoming thesauri of the English and Serbian languages.
Cross-Linguistically Viable Treatment of Tense and Aspect in ParallelGrammar Development

This paper reports on a robust treatment of tense and aspect that is designed for computational purposes such as the crosslinguistically broad ParGram effort. Our ParTMA (Parallel Tense/Mood/Aspect) project builds on theoretical insights within formal semantics and pragmatics, but places them on a broader crosslinguistic footing and develops a computationally viable interface between morphosyntax and semantics/pragmatics. We illustrate how our approach works with respect to selected phenomena that include tense underspecification, morphosyntactic variation and sequence of tense effects.
REMOTE SENSING AND DATA ASSIMILATION FOR SURF ZONE BATHYMETRIC INVERSION

We demonstrate the implementation and validation of a surf zone forecasting system, which uses remote sensing observations to control errors in surf zone bathymetry. This system uses ensemble-based sequential data assimilation techniques, which are adaptable to arbitrary geophysical observations, and/or arbitrary improvements to model physics. The system is validated using data from a 2010 field experiment at Duck, NC (U.S.A.), and is shown to produce accurate corrections to bathymetry, leading to improvements in prediction of currents.
