Relationship between hydrological, physical and chemical characteristics present in rainwater runoff sediments

espanoll objetivo de este trabajo fue establecer posibles relaciones entre caracteristicas de lluvias y caracteristicas fisicas y quimicas de sedimentos en una cuenca experimental ubicada en la ciudad de Bogota (region tropical altoandina). Los sedimentos se recolectaron en periodos quincenales durante cinco meses, en los dos desarenadores del humedal construido de la Pontifica Universidad Javeriana, Bogota. La recoleccion de sedimentos se realizo con trampas especialmente disenadas para el sitio de estudio. Los resultados muestran un diametro medio (D50) de 128 µm, concentraciones medias de Cr = 36 mg/kg, Cu = 115 mg/kg, Pb = 273 mg/kg y Zn = 1173 mg/kg. Se encontro una relacion entre la precipitacion y las caracteristicas de los sedimentos, lo cual puede guiar eventuales practicas de utilizacion de sedimentos: (i) un menor numero de dias de tiempo seco se relaciona con mayores tamanos de particulas y menores concentraciones de metales; (ii) mayores magnitudes de intensidad y de altura total de lluvia se relacionan con una menor cantidad de particulas de grano grueso que llegan a los desarenadores EnglishThe objective of this work was to establish possible relationships between rainfall characteristics and physical and chemical characteristics of sediments in an experimental catchment in Bogota city (tropical mountain Andean region). The sediments were collected fortnightly for five months, from the two sand traps of the constructed wetland of the Pontificia Universidad Javeriana, Bogota. We collected the sediments with traps specially designed for the study site. The results show a mean diameter (D50) of 128 μm, mean concentrations of Cr = 36 mg/kg, Cu = 115 mg/kg, Pb = 273 mg/kg and Zn = 1173 mg/kg. We found a relationship between rainfall and sediment characteristics, which eventually could guide practices for sediment usages: (i) a reduced number of dry days is related to higher particle diameters and lower concentrations of metals; (ii) higher magnitudes of rainfall intensities and total heights are related to a lower number of particles with large grain sizes reaching the sand traps.
Obstructive Sleep Apnea Educational Intervention of Dental Hygiene Students

Study Objectives: Oral health professionals (OHPs) have a unique opportunity to screen for obstructive sleep apnea (OSA) but receive limited education about OSA. This study determined whether an online educational intervention could significantly increase the knowledge of information relevant to OSA screening in individuals studying dental hygiene (DH). Methods: A 17-question, comprehension-based pretest and posttest assessed OSA knowledge. The convenience sample consisted of students enrolled in the first year of the DH program at Eastern Washington University in 2017. Participants completed the pretest, viewed the OSA educational video, completed a posttest, and then completed a second posttest 2 weeks following completion of the educational module. Pretest and first posttest answers were compared to determine a change in knowledge. First posttest and second posttest answers were compared to evaluate knowledge retention. Results: Thirty-three participants completed the pretest and posttest, and 28 (85%) completed the second posttest. Participants had a significant improvement in first posttest scores (p < .001, t(33) = 9.836) and second posttest scores (p < .001, t(28) = 5.653) compared to pretest scores. Following completion of the online educational module, all participants (n=33) indicated they believed screening for OSA was important, and 76% of participants (n=25) indicated they were likely or very likely to evaluate adult patients for OSA. Conclusions: An online OSA educational module is an effective educational strategy to increase students’ knowledge of OSA.
The Future of Teaching English in Saudi Arabia

Even though the future is unknown and may be hard to forecast, its formulation can still be influenced by the making of some decisions in the present time (Amara, 1981). This article reviews the TEFL situation in Saudi Arabia in the past and the present, and offers some recommendations for improving it in the future. These recommendations will include policy and school-based levels. The article will include discussions about the Saudi government's strategies of enhancing the education system through Information Communication Technology (ICT), future teaching systems, teachers and students' roles, future teacher education, important issues in assessment as well as recommendations for policy regarding critical issues for EFL instruction in Saudi Arabia, including a detailed examination of the Tatweer project, which is the Saudi Arabian government policy to be implemented between 2013-2023, with the aim of developing public education in Saudi Arabia.
GENERAL HIGHER-ORDER DYNAMIC OPIAL INEQUALITIES WITH APPLICATIONS

ABSTRACT. In this paper, we present some new generalizations of dynamic Opial-type inequalities of higher order on time scales. The results contain as special cases many of the results currently given in literature. As an application, we apply these inequalities together with a Hardy-type inequality on time scales to establish some lower bounds of the distance between zeros of a solution and/or its derivatives for a fourth-order dynamic equation.

Corporate Social Responsibility Practices in Bangladesh: Evidence from Engineering and Pharmaceutical & Chemical Industry

: To ensure the existence in the ever growing competitive business environment, CSR should be a continuing commitment of every business organization to recognize them as environmentally and socially responsible. This paper focuses on identifying the extent of corporate social responsibility Disclosures (hereafter CSRD) practices by the companies operating in Bangladesh. An effort has also been exerted to determine whether the practice varies with respect to industries, companies within an industry and also in terms of CSR categories. To meet these objectives 28 companies under Engineering Industry and 22 companies under Pharmaceutical & Chemical Industry have been taken covering the period 2010 to 2014. Here, data has been collected from the annual reports of the companies under consideration. Content analysis has been conducted based on a Disclosure Checklist developed with the help of previous relevant literatures and also by taking the specific nature of the mentioned industries into account. To draw conclusion, Disclosure Index Scores (DIS) have been calculated by using the outcomes of content analysis. Up to 2013 an increasing trend in CSRD practices has been noticed in case of both industries but in 2014 it remained same as that of 2013. Results show that companies under both industries disclose more information about products and services they are dealing with. However, Disclosure Index Scores with respect to environmental disclosure of companies under Engineering and Pharmaceutical & Chemical Industry are 0.05 and 0.18 respectively which are the least out of all scores. This indicates companies of Bangladesh are still not that much concern in devising policies about how to deal with the environment within which they are operating. DIS substantiate that
The Value of Ultrasound and Color-Doppler Features in the Assessment of Single Solid Thyroid Nodule

Background The use of ultrasound (US) in the assessment of thyroid disease has greatly increased the detection of small thyroid nodules unrecognized at clinical examination. Objective To determine the accuracy of the diagnosis of the nature of solitary thyroid nodule by ultrasound in comparison with histopathological findings and to correlate the different sonographic and colorDoppler (CFD) findings with the results of histopathology of resected nodules. Methods The nodule size, echogenicity, presence/absence of calcification, lesion margins and vascular pattern of 63 patients with solitary thyroid nodule referred for US assessment). Results Twenty four patients (38.1%) had malignant thyroid nodules and 39 patients (61.9%) had benign nodules as confirmed by histopathology. The large nodules show benign histopathological finding more than the small nodules (no significant difference; 56.5% vs. 25.4%, respectively). Histologicallyconfirmed malignant lesions show hypoechoic appearance and calcification more than benign nodules. The Malignant lesions presented more frequently than did benign nodules as solid hypoechoic appearance and irregular or blurred margins (52.2% vs. 47.8%;), and intranodular vascular pattern with calcification (63.3% vs. 36.4%) and the sensitivity and specificity by ultrasound in the evaluation of these nodules will be more and have highly diagnostic accuracy (58.3%, 79.49%, 71.5% respectively) in comparison to the former feature (50%, 71.79%, 63.5% respectively). Conclusion We conclude that the typical appearance of nodules in thyroid carcinoma is irregular hypoechoic mass with internal vascularity and calcifications. Uncommon appearances of carcinoma include hyperechoic texture, intrinsic hypovascularity, and sharp regular contours. Uncommon sonographic features were found to occur more often than expected.
Heterogeneous Banks and Technical Change in an Evolutionary Model of Endogenous Growth and Fluctuations

We employ an evolutionary, agent-based model with an imperfect credit market composed of heterogeneous banks to analyze some features of the current global crisis by exploring the transmission mechanisms from finance to real dynamics at an economy-wide level. The model describes an economy composed of capitaland consumption-good firms, workers, and banks. Capital-good firms perform R&D and produce heterogeneous machine tools. Consumption-good firms invest in new machines and produce a homogeneous consumption good. Banks finance firms production and investment plans. Before carrying out policy analysis, we empirically validate the model showing that it is able to replicate a wide spectrum of macroeconomic and microeconomic stylized facts. In line with the literature on financial fragility, policies impacting on the financial side of the economy affect production and investment decisions of firms and can amplify or dampen business cycle fluctuations.
omparative Ultrastructure and Molecular hylogeny of Selenidium melongena n . p . and S . terebellae Ray 1930 emonstrate Niche Partitioning in Marine regarine Parasites ( Apicomplexa )

regarine apicomplexans are a diverse group of single-celled parasites that have feeding stages trophozoites) and gamonts that generally inhabit the extracellular spaces of invertebrate hosts livng in marine, freshwater, and terrestrial environments. Inferences about the evolutionary morphology f gregarine apicomplexans are being incrementally refined by molecular phylogenetic data, which uggest that several traits associated with the feeding cells of gregarines arose by convergent evoluion. The study reported here supports these inferences by showing how molecular data reveals traits hat are phylogenetically misleading within the context of comparative morphology alone. We examned the ultrastructure and molecular phylogenetic positions of two gregarine species isolated from the paghetti worm Thelepus japonicus: Selenidium terebellae Ray 1930 and S. melongena n. sp. The ultratructural traits of S. terebellae were very similar to other species of Selenidium sensu stricto, such as aving vermiform trophozoites with an apical complex, few epicytic folds, and a dense array of microubules underlying the trilayered pellicle. By contrast, S. melongena n. sp. lacked a comparably discrete ssembly of subpellicular microtubules, instead employing a system of fibrils beneath the cell surface hat supported a relatively dense array of helically arranged epicytic folds. Molecular phylogenetic nalyses of small subunit rDNA sequences derived from single-cell PCR unexpectedly demonstrated hat these two gregarines are close sister species. The ultrastructural differences between these two pecies were consistent with the fact that S. terebellae infects the inner lining of the host intestines, and . melongena n. sp. primarily inhabits the coelom, infecting the outside wall of the host intestine. Altoether, these data demonstrate a compelling case of niche partitioning and associated morphological ivergence in marine gregarine apicomplexans. 2014 Elsevier GmbH. All rights reserved.
EVOLVING SUSTAINABLY : A LONGITUDINAL STUDY OF CORPORATE SUSTAINABLE DEVELOPMENT

This study operationalizes corporate sustainable development and examines its organizational determinants. Data for this project pertain to Canadian firms in the oil and gas, mining, and forestry industries from 1986 to 1995. I find that both resource-based and institutional factors influence corporate sustainable development. By exploring time-related effects, I also find that media pressures were important in early periods and resource-based opportunities endured over time. This finding challenges the assumption that firms first adopt innovations in response to technical rewards which are later institutionalized. These counter-intuitive results may be attributable to the unique characteristics of the dependent variable, corporate sustainable development. They raise important questions and directions for future research. Copyright  2004 John Wiley & Sons, Ltd.
TIME DEPENDENT ANALYTICAL MODELLING OF MULTI ~ FREQUENCY CAPACITIVELY COUPLED COLLISIONAL SHEATH

Capacitively coupled plasma (CCP) has been widely used in plasma assisted processing such as plasma etching, deposition and other surface treatments in microelectronics industries. High plasma density and ion bombarding energy, which are crucial in these applications, particularly in etching, cannot be controlled independently in traditional single frequency (SF) driven CCP. Dual frequency (DF) CCP is already in use in the fabrication industries for the new generation ultra-large-scale integrated (ULSI) circuits. But it is reported that the quality of separate control of ion energy and flux in DF discharge is limited due to the coupling of two frequencies and effect of secondary electrons. It is not very far that more frequencies will be used simultaneously in the CCP in order to achieve better control etch parameters. An analytical model of sheath parameters for a multi-frequency driven collisional CCP has been developed considering time dependent ion density and electric field within the sheath. Sheath parameters for DF and triple frequency (TF) case have been determined and studied against different operating parameters, e.g., chamber pressure, plasma density, RF frequencies, phase differences etc. The determined values of the sheath parameters are compared with some published DF and TF models. In the analyses for DF and TF case different properties of sheath width and potential have been observed. The oscillating behaviour of the parameters increases as the number of RF source frequencies increases. More oscillation in the sheath parameters increases the ion-neutral collisions within the sheath resulting in a reduced ion bombarding energy at the electrode. The oscillation pattern of the parameters depend on the ratio of RF frequencies. Compared with collisional time independent models this model estimates lower values of the sheath parameters. Lower values of the parameters is another reflection of the lower ion energy. The sheath parameters show inverse relationship with both pressure and plasma density. The parameters also show smaller values at higher pressure ranges when compared with a collisionless time dependent model, as collisionality is not considered in that model. It has been found that proper choice of phase difference may facilitate to have better control over the sheath properties. As this model considers the instantaneous ion motion and the instantaneous electric field, so this model will estimate the sheath parameters of CCP more accurately when multi-frequency source is used. This will facilitate the plasma users to have better control on the etch properties.

Renmin University of China and Zhejiang Gongshang University at TRECVID 2018: Deep Cross-Modal Embeddings for Video-Text Retrieval

In this paper we summarize our TRECVID 2018 [1] video retrieval experiments. We participated in two tasks: Ad-hoc Video Search (AVS) and Video-to-Text (VTT) Matching and Ranking. For the AVS task, we develop our solutions based on W2VV++, a super version of Word2VisualVec (W2VV) [4]. For the VTT task, our entry is built on the top of a recently proposed dual encoding network [5], which encodes an input, let it be a video or a natural language sentence, at multiple levels. The 2018 edition of the TRECVID benchmark has been a fruitful participation for our joint-team, resulting in the best overall result for both AVS and VTT tasks. Retrospective experiments show that our ad-hoc video search system, used as is, also out-performs the previous best results of the TRECVID 2016 and 2017 AVS tasks. We have released feature data at https: // github. com/ li-xirong/ avs .
Negotiating with frictions Volker Britz

We consider bilateral non–cooperative bargaining on the division of a surplus. Compared to the canonical bargaining game in the tradition of Rubinstein, we introduce additional sources of friction into the bargaining process: Implementation of an agreement and consumption of the surplus can only begin at discrete points in time, such as the first day of a month, quarter, or year. Bargaining rounds are of non–trivial length, so that counter–offers may be made without triggering costly delay. Communication between players is noisy: When players make offers, they are uncertain about the time it takes for the offer to arrive. We analyze delays and payoffs in the unique stationary equilibrium of the game. Frictions tend to make the bargaining process less efficient, but lead to a fairer surplus allocation. We establish conditions under which the equilibrium outcome converges to that in a canonical bargaining model as frictions become small. JEL Codes: C72, C78
The kinematic history of the Khlong Marui and Ranong Faults , Southern 1 Thailand 2 3

8 The Khlong Marui Fault (KMF) and Ranong Fault (RF) are major NNE 9 trending strike-slip faults which dissect peninsular Thailand. They have been 10 assumed to be conjugate to the NW-trending Three Pagodas Fault (TPF) and 11 Mae Ping Fault (MPF) in Northern Thailand, which experienced a diachronous 12 reversal in shear sense during India – Eurasia collision. It follows that the KMF 13 and RF are expected to show the opposite shear sense and an inversion at a 14 similar time to the TPF and MPF. New field data from the KMF and RF reveal 15 two phases of ductile dextral shear separated by Campanian magmatism. 16 Paleocene to Eocene post-kinematic granites date the end of this phase, while a 17 brittle sinistral phase deforms the granites, and has exhumed the metamorphic 18 rocks. The timing of these movements precludes formation of the faults in 19 response to Himalayan extrusion tectonics. Instead, they formed near the 20 southern margin of a late Cretaceous – Paleocene orogen, and may have been 21 T P I R C S U N A M D E T P E C C A ARTICLE IN PRESS 2 influenced by variations in the rate of subduction ahead of India and Australia. 22 North-south compression prior to reactivation of the subduction zone around 23 southern Sundaland in the Eocene caused widespread deformation in the over24 riding plate, including sinistral transpression on the KMF and RF. 25 26
Age-structure, human capital and economic growth in developing economies: A disaggregated analysis

It is attempted to explore the role of change in age-structure and human capital in economic growth of developing countries. A disaggregated panel analysis of 67 developing economies across regions and income groups over the time period of 1960-2014 is conducted. Difference Generalized Method of Moments (Diff-GMM) is employed to overcome the panel-specific problems particularly endogeneity and reverse-causation. The results reveal that changes in age-structure and human capital positively influence economic growth at all disaggregated levels. However, the effect is more powerful in relatively developed regions and high income groups. There is high speed of convergence for less developed economies and vice versa. It may be concluded that change in age-structure and human capital affect the regional and income groups of the economies by different magnitude and pace. Based on empirical results, the Sub-Saharan Africa and low-income economies where transition in age-structure is in its initial phase, population policies should be focused on reducing fertility to accelerate the economic growth. Human capital growth should be another part of the policy for having the demographic dividends.
Prevalence and Intensity of Plasmodium Infection Among Pregnant Women Attending Anti-Natal Clinics in Awka Metropolis

Malaria in pregnancy is a leading cause of mortality in pregnant women and foetus. A study on the prevalence and intensity of Plasmodium infection among pregnant women attending clinics in Awka metropolis, Anambra State was carried out between October 2015 and February 2016. Finger prick method was used in collecting blood from 577 pregnant women that attended antenatal clinics and the blood samples were examined for Plasmodium parasite and intensity of infection. Information obtained were analyzed using simple ratios, percentages and charts, chi-square was used to test associations among variables at 95% level. Of the 577 pregnant women examined, 358 (62.0%) were positive for Plasmodium parasite. Two hundred and thirteen (59.5%) had mild infections, 131 (36.6%) moderate and 14 (3.9%) severe infections. Higher prevalence was recorded among young pregnant women, 15-24 years at 65.4% and the difference was statistically significant (p<0.05). The difference in prevalence among parity and trimester was also statistically significant (p<0.05). Prevalence of Plasmodium infection was higher among nonusers (76.6%) and difference depending on frequency of ITN usage was significant (p<0.05).
BENCHMARK CONTROL PROBLEM FOR SEISMIC RESPONSE ANALYSIS OF A HIGHWAY BRIDGE

The seismically excited benchmark problem is based on the newly constructed 91/5 highway overcrossing in Southern California. The goal of this effort is to develop a standardized model of a highway bridge using which competing control strategies, including devices, algorithms and sensors, can be evaluated comparatively. To achieve this goal, a 3-D finite-element model is developed in MATLAB to represent the complex behavior of the full-scale highway crossing. A MATLAB based nonlinear structural analysis tool has been developed and made available for nonlinear dynamic analysis. The nonlinear behavior of center columns and isolation bearings are considered in formulating the bilinear force-deformation relationship. The effect of soil-structure interaction is also considered by modeling the interaction using equivalent spring and dashpot. The representative ground motions are considered to be applied simultaneously in two directions. Sample control devices are assumed to be installed between the deck and the end-abutments of the bridge. Evaluation criteria and control constraints are specified for the design of controllers in this benchmark problem.
