Modelling current efficiency and ohmic potential drop in an innovated electrocoagulation reactor

The objective of the present work is to study the impact of the electrodes configuration utilized in an innovated electrocoagulation reactor on the behavior of current efficiency and the ohmic potential drop via the treatment of real oily wastewater released from crude oil wells location (West Qurna 1 /Basra-Iraq). A monopolar mode of triple aluminum tubes was employed in a concentric arrangement to investigate the purpose of this work under the influences of the operational variables; the electrolysis time (10, 14, 25, 36, 40 min) and electric current density (1.75, 2.53, 4.39, 6.25, 7.02 mA/cm2). The initial pH equaling 6.5 and the mixing speed was taken as 200 rpm. The results reveal a significant effect of the invented electrodes configuration on the studied responses values where they had decreased from 150 to 125% and 67.85 to 66.19 ohm respectively as the electrolysis time increases from 10 to 40 min whereas the ohmic drop raises from 28.02 to 107.64 ohm as the current density increased from 1.75 to 7.02 mA/cm2 but the current efficiency had minimized from 157 to 114% for the same increment in current density. The lower values of the operational variables, the higher value of the current efficiency which is the most significant response. This study proved a notable efficiency of the present design of the electrocoagulation reactor.

NUEVAS ALTERNATIVAS FARMACOLÓGICAS PARA ANALGESIA POSOPERATORIA MULTIMODAL

El control del dolor en el período postoperatorio es una labor fundamental del anestesiólogo. Sin embargo, a pesar de nuestros progresos, el manejo de este síntoma sigue sin ser el óptimo: un número significativo de pacientes presenta dolor moderado a severo; por otra parte, del tratamiento del mismo se derivan síntomas secundarios considerables. Además, se ha reconocido al dolor crónico postoperatorio como un fenómeno mucho más frecuente de lo que se pensaba. Los nuevos conocimientos sobre la fisiología del dolor han permitido aumentar los recursos farmacológicos con drogas que actúan en sitios específicos de las vías nociceptivas. El tratamiento del dolor a distintos niveles debiera disminuir la frecuencia y severidad del dolor agudo postoperatorio y/o evitar el establecimiento de un dolor crónico post operatorio, con menos efectos adversos. Estos elementos constituyen la base del desarrollo de la analgesia multimodal. Entre las drogas que podrían tener alguna acción en la modulación del procesamiento del estímulo nociceptivo, tenemos a la ketamina, a la lidocaína y a la gabapentina. La ketamina ha demostrado ser una droga efectiva en disminuir el consumo de opioides y el dolor agudo postoperatorio con un bajo nivel de efectos adversos secundarios, pero se necesita caracterizar mejor las dosis y la vía de administración más adecuada. La administración de infusiones de lidocaína podría tener alguna utilidad en pacientes sometidos a cirugías con un gran componente de sensibilización central. Los estudios con gabapentina sugieren un rol en el manejo del dolor agudo postoperatorio; está pendiente definir qué pacientes son los que más se benefician con esta droga. Estas drogas (debido al mecanismo de acción de cada una de ellas) tendrían un rol en la prevención del establecimiento de dolor crónico postoperatorio, pero son escasos aun los trabajos en esta línea.
Bugs on the Brain: A Mental Model Matching Approach to Cognitive Skill Acquisition in a Strategy Game

This study investigated the development of player skill and cognitive understanding of a game over repeated plays to (a) bridge separate research traditions on skill acquisition and games learning and (b) provide deeper insight into the process of developing mental models of games. 325 participants responded to an online questionnaire with questions concerning their experience with the game, Hive, as well as both openand closed-ended items designed to compare their understanding of the game to an expert’s understanding. Open-ended items were content analyzed and modeled as a latent variable. As predicted, both player skill and mental model matching were positively associated with number of plays. Additionally, while player skill had a curvilinear relationship with number of plays that indicated diminishing returns on additional plays, that between cognitive understanding and plays appeared to be linear. The implications of these findings for the cognitive underpinnings of player skill—and for mental model matching theory in particular—are discussed.

Two-Fund Separation under Homogeneous Ambiguity

This paper derives two-fund separation for an economy with agents of multiple-priors utility: Given homogeneous sets of priors and linear risk tolerance felicity functions, an interior equilibrium is Pareto efficient and all agents hold a combination of the riskless security and the market portfolio (i.e., aggregate endowment). This result permits the construction of a representative agent whose preferences follow the multiple-priors model with a utilitarian von-Neumann-Morgenstern utility function.

The role of age structure

There are strong life cycle patterns in practically all kinds of human behavior as well as in the resources and capabilities of individuals. Variations in the age structure of the population therefore affect all aspects of the aggregate economy, not only saving as is generally recognized. Swedish post-war development exhibit patterns of age structure effects on saving, growth, investment, current account, budget balance and inflation that are consistent with the dynamics of these variables in historic cycles, only these effects apply to much longer periods. The deviations of actual time series from the model predictions are consistent with the institutional detail of economic policy and its fluctuating directions over the post-war period. The poor performance of the Swedish economy during the period 1975-1995 can partly be explained by inappropriate policies working against the underlying age structure changes. The rapid expansion of nonworking elders in the population in the 1980s was simultaneous with the depletion of the more experienced part of the older work force. This would according to our estimates put strong downward pressure on the budget balance and the current account. Swedish economic policy aimed at current account balance, mainly by a series of devaluations in the early 1980s did succeed in improving the current account. The cost of this was a serious overheating of the economy in the end of the 1980s since fundamental behavior and resources in the population did not back this policy. The attempts to nevertheless fix the exchange rate at an unrealistically high level (the price of a dollar in 1992 was close to half of today’s rate) led into a serious crisis and depression in the beginning of the 1990s. Our conclusion is that it is a serious mistake for macroeconomic modeling to ignore the general equilibrium effects of changing age distributions.
8th Iberian Meeting on Colloids and Interfaces (RICI8)

Nanotechnological solutions for biomedicine underlie the need to carefully validate biocompatibility of the developed technology and eventual exposure risk [1]. Many lipids have been used to produce liposomes, which mimic cell membranes and are very interesting in terms of interaction with cells, tissues and organs. The features of liposomal formulations are dependent on the lipid characteristics, such amphiphile shape, electrical charge and constitution of the lipid mixture [2]. Our group developed a Dimethyldioctadecylammoniumbromide (DODAB) and monoolein (MO) formulation that was validated for delivery of different biomolecules [3] and is now being optimized for protein delivery. These liposomes were compared with a novel liposomal formulation, which consists in a mixture of 5 different lipids similarly to vesicles produced by human cells. The purpose of this comparative study was to identify the most suitable formulation for efficient delivery of proteins, specifically of bioactive cytokines, to human cells with the minimal toxicity. Both types of formulations were characterized in terms of size (DLS), surface charge (zeta potential) and stability. Using small quantities of model protein bovine albumin serum (BSA), we optimized the sensitivity of the quantification by the Bradford method, to calculate encapsulation efficiency in both systems. Toxicity was evaluated using in vitro animal cell models (MTT assay), hemolysis assessment (spectroscopy). The balance between efficiency in cargo loading and delivery, and toxicity assessment, is crucial to better adjust the formulation according to the intended application.
Implant Safety Tool Application to Assist the Assessment of Radio-Frequency Radiation Exposure

This paper discusses a new Implant Safety Tool, used to assess the safety of patients with metal implants exposed to radio-frequency (RF) fields. This specialist tool is discussed on the example of pectus patients with titanium bar-implant inserted during the minimally invasive Nuss procedure. The authors created a 3D realistic model of a 34-year-old male patient with a Nuss bar-implant. A numerical analysis based on the finite-difference time-domain (FDTD) method was performed for a far field source in the form of a plane wave with the frequency of 64 MHz, which corresponds to the RF exposure generated by MRI devices at 1.5 T. The obtained results allow concluding that the concave Nuss bar-implant poses no risk during environmental and occupational RF field exposures.
Onsets, Activity, and Events: A Multi-task Approach for Polyphonic Sound Event Modelling

State of the art polyphonic sound event detection (SED) systems function as frame-level multi-label classification models. In the context of dynamic polyphony levels at each frame, sound events interfere with each other which degrade a classifier’s ability to learn the exact frequency profile of individual sound events. Frame-level localized classifiers also fail to explicitly model the long-term temporal structure of sound events. Consequently, the event-wise detection performance is less than the segment-wise detection. We define ‘temporally precise polyphonic sound event detection’ as the subtask of detecting sound event instances with the correct onset. Here, we investigate the effectiveness of sound activity detection (SAD) and onset detection as auxiliary tasks to improve temporal precision in polyphonic SED using multi-task learning. SAD helps to differentiate event activity frames from noisy and silence frames and helps to avoid missed detections at each frame. Onset predictions ensure the start of each event which in turn are used to condition predictions of both SAD and SED. Our experiments on the URBAN-SED dataset show that by conditioning SED with onset detection and SAD, there is over a three-fold relative improvement in event-based F -score.
Compositional Video Prediction (Supplementary)

Entity Predictor. Our predictor leverages the graph neural network family, whose learning process can be abstracted to iterative message passing and message aggregation. In each round of message passing, each node (edge) is a parameterized function of their neighboring node and edges, which updates their parameters by back propagation. We introduce the predictor architecture by instantiating the message passing and aggregation operation as following: For the l-th layer of message passing, it consists of two operations:
FLEXIBLE FORMS OF EMPLOYMENT IN POLAND

Changing environment means changing organizations – this process is an effect of striving for a continued existence in a turbulent environment. Organizations must quickly innovate and adapt to the new requirements of the market. Globalization and increasing competition make companies responding quickly to change [Kim et all, 2012], therefore, increasingly, companies focuses on more efficient use of the most precious resource human capital[Guest at all, 2006]. This new approach is especially conspicuous in knowledge-intensive sectors [Süβ, Sayah, 2013]. The traditional model of employment involves, usually, fix employment’s costs, whereas flexible forms give the opportunity to control the labour’s costs and allow employers to use effectively human resources, including recruitment of professionals. New forms of employment aim at development of employees and, as a consequence, keeping the talented staff in organization who, by their knowledge, skills and qualifications, constitute a strategic resource for the enterprise. The financial aspect, which concerns the burden of employer’s costs also causes, that flexible forms of employment have become a form of occupational activation, which is identified with the following groups of workers: young people with no experience, students, mothers combining the family life and working life, disabled and long-term unemployed. The aim of the paper is the identification of flexible forms of employment, having an impact on better exploiting the potential of the human resource.
EMPLOYING WIKIS AS EDUCATIONAL TOOLS TO DEVELOP A COMMUNITY OF INQUIRY

The current study attempts to evaluate the integration of wikis as an educational tool within the teaching and learning process in order to achieve specific educational objectives. The wiki was developed and integrated into the Linguistics and Literature course in order to deliver the fairy tale entitled “The Prince of Venice. ” The study also aimed to define in detail the teacher and student roles when a wiki is integrated as an educational tool. Thus, it examined teacher and student participation (quality and quantity), contribution, interest, reactions, etc., throughout the teaching and learning process. Additionally, the study aimed to identify the role of technology, and in this case the wiki, through the teaching and learning process in successfully achieving the learning objectives of the lesson. Finally, the study examined the development of a Community of Inquiry (CoI) through the integration of a wiki to deliver the fairy tale. A mixed method approach was employed in order to achieve the scope of the study. Data collection methods employed included questionnaires, reflective journals, observations and interviews. The CoI survey instrument, and specifically the 34 parameters of the survey served as the basic criteria to quantitatively examine the development of a CoI within a wiki environment. Reflective journals completed by the teachers, classroom observations completed by an observer and finally interviews with the students collected mainly qualitative data. The population of the study was 5 graders. For the study a wiki was developed (http://fairytale2012.wikispaces.com/). The data collection process took place in October-November 2012, and the authors are in the process of analyzing the data collected. Introduction and Theoretical Background Web 2.0: Definitions and Tools The technological advancement in information technology and telecommunications resulted in the development of the Web 2.0 and created the appropriate framework for user participation. The traditional one-way communication is transformed to a two-way communication, and process of information. In Web 2.0 users are contributing, collaborating, creating the 3C's (Ala-Mutka, Punie, & Ferrari, 2009). Millions of people use various social and professional networks, such as Facebook, MySpace, Twitter, Delicious, Flickr, LinkedIn, Live Journal. Discussion forums, blogs, wikis, chat-rooms, electronic calendars, electronic documents (i.e., Google documents), etc., are some of the Web 2.0 tools used within the networks. ICICTE 2013 Proceedings
New Features for Speech Activity Detection

This paper discusses two new features for speech activity detection(SAD), using a multi-layer perceptron(mlp) trained to predict phoneme from acoustic features. The ﬁrst feature is based on the difference between speech and noise histogram of certain phonemes. A scoring mechanism is formulated to score the softmax probabilities of the frames of a phoneme. The second feature is based on the correlation between softmax probabilities of the edge frames for certain phoneme transitions. A probabilistic approach is formulated to score the phoneme transition. Relevant datasets are used to prove the robustness of the proposed features in terms of speech activity detection.
Importancia diagnóstica del leucograma en la etapa febril y post-febril en adultos

Investigation of Toxic Metals in the Tobacco of Pakistani Cigarettes Using Proton-Induced X-Ray Emission

A particle-induced X-ray emission (PIXE) study has been carried out to find out whether available local and imported cigarette brands in Pakistan have elevated concentration of metals or not. The results are compared within the brands examined in this study and with the results of related studies in literature. A sum of 19 different cigarette brands was purchased randomly from different Pakistani markets which included local and imported brands. The concentration of elements like Cd, Pb, Zn, Fe, Mn, Ni, Cu, and Co was investigated. Results showed that different cigarette brands have different metal contents. The mean concentration of the heavy metals is Cd—4.92 μ g/g, Co—0.12 μ g/g, Cu—0.97 μ g/g, Ni—0.13 μ g/g, Pb—1.02 μ g/g, and Zn—12.91 μ g/g per dry weight. Compared with the reported results of other international studies, Pakistani cigarettes are observed to have lower heavy metal contents except for cadmium which was higher. This study will provide adequate data for all concerned depart-ments. This study will also create awareness among people about the toxicity of metals present in tobacco of cigarettes.
AUTOMATIC RECOGNITION OF KEY- WORDS USING N-GRAMS

Documentary research (e.g. bibliography for a thesis or a research project, technological monitoring, etc.) is often based on a few selected keywords. Yet, experience shows that other words may be characteristic of the topic of interest. Discovery and use of those in text searches often leads to relevant documents. The authors propose a fully automatic method to discover such key-words from a set of texts deemed characteristic of the topic of interest. The method relies on n-gram coding of the texts, identi cation of characteristic n-grams in a subset of the texts, and nally searching for words containing one or many of the characteristic n-grams. An example using 6709 Reuters news briefs sampled from the 10 most common classes. Discriminating one class from the others serves to simulate the topic-of-interest situation. Each discrimination yields a set of candidate key-words . This is compared to searching of topic-related words. Using n-grams appears to be more e cient as speci c roots show up in the n-grams; it is automatic and does not require prior linguistic analysis.
