MAGIC observations of the February 2014 flare of 1ES 1011+496 and ensuing constraint of the EBL density

Context. In February-March 2014, the MAGIC telescopes observed the high-frequency peaked BL Lac 1ES 1011+496 (z=0.212) in flaring state at very-high energy (VHE, E>100GeV). The flux reached a level more than 10 times higher than any previously recorded flaring state of the source. Aims. Description of the characteristics of the flare presenting the light curve and the spectral parameters of the night-wise spectra and the average spectrum of the whole period. From these data we aim at detecting the imprint of the Extragalactic Background Light (EBL) in the VHE spectrum of the source, in order to constrain its intensity in the optical band. Methods. We analyzed the gamma-ray data from the MAGIC telescopes using the standard MAGIC software for the production of the light curve and the spectra. For the constraining of the EBL we implement the method developed by the H.E.S.S. collaboration in which the intrinsic energy spectrum of the source is modeled with a simple function (< 4 parameters), and the EBL-induced optical depth is calculated using a template EBL model. The likelihood of the observed spectrum is then maximized, including a normalization factor for the EBL opacity among the free parameters. Results. The collected data allowed us to describe the flux changes night by night and also to produce di_erential energy spectra for all nights of the observed period. The estimated intrinsic spectra of all the nights could be fitted by power-law functions. Evaluating the changes in the fit parameters we conclude that the spectral shape for most of the nights were compatible, regardless of the flux level, which enabled us to produce an average spectrum from which the EBL imprint could be constrained. The likelihood ratio test shows that the model with an EBL density 1:07 (-0.20,+0.24)stat+sys, relative to the one in the tested EBL template (Domínguez et al. 2011), is preferred at the 4:6 σ level to the no-EBL hypothesis, with the assumption that the intrinsic source spectrum can be modeled as a log-parabola. This would translate into a constraint of the EBL density in the wavelength range [0.24 μm,4.25 μm], with a peak value at 1.4 μm of λF_ = 12:27^(+2:75)_ (-2:29) nW m^(-2) sr^(-1), including systematics.

BURNOUT: analisando a síndrome do ramo das indústrias alimentícias do Rio Grande do Norte

This paper aims to verify the Burnout´s possibilities of incidence, finding the creating dimensions and comparing with the socio-demographics characteristics of the researched professionals. This quantitative-descriptive search has a population of 197 workers of 23 nourishing companies in Rio Grande do Norte. This population is predominantly male, younger than 28 years old, single, relatively instructed (57,07% with complete high school) and having just started their current job since 79% of the interviewees are in the company less than six years. The AUDITORIA DO SISTEMA HUMANO (ASH) model, utilized for investigation and developed for the Spaniards Quijano and Navarro in 1999, has several dimensions about human resources management and the organizational effectiveness, but only makes part of the research in 19 questions Burnout referring. It was used factorial analyses with extraction method, varimax rotation and Kaiser normalization with the intuition to define the creating dimensions of the syndrome, they were evaluated with Cronbach Alpha coefficient after extraction. The dimensions found through the factorial analyses were: emotional exhaustion, physical exhaustion and vitality. The accumulated explanation value reached 65,30% of total variation. The data socio-demographics don t justify the syndrome appearance, because the T test and ANOVA showed irrelevant values. It has been also observed that the founded dimensions were different of the Maslach sociopsychological perspective (emotional exhaustion, depersonalization and low professional realization) allowing comparison with others researches and the possibility to develop new ones with workers from different assistance areas. These new researches are important, since the syndrome refers to chronic labor stress consequences and any professional is favorable to Burnout, harmful to the company as to the collaborators

De MARC a CEPAL o cualquier otro formato y viceversa

El propósito de este artículo es práctico: enseñar al usuario de Winisis a reformatear las bases de datos diseñadas e implementadas en cualquier formato, normalizado o no, convirtiéndolas al formato de interés de la unidad de información.Winisis es un paquete que permite utilizar cualquier nomenclatura en la definición de las etiquetas que identifican los campos. Este aspecto es una ventaja y una desventaja porque permite libertad en la selección del formato a utilizar, pero, se generan una gran diversidad de formatos en las unidades de información, dificultando la compatibilidad en los sistemas automatizados de catalogación, la normalización y la transferencia efectiva de la información entre unidades de información.Algunos problemas que enfrentan los bibliotecólogos en su trabajo cotidiano al normalizar la información son por ejemplo:a) la diversidad de bases de datos sin normalización, b) la variación entre formatos, c) los diferentes números, etiquetas y nombres de los campos que integran las bases de datos, e incluso bases de datos creadas con diferentes versiones de Microisis; d) un catálogo automatizado en un formato sin normalización; e) para la participación en una red y exige la reconversión del catálogo al formato común de la red. En algunos casos se ha optado por digitar de nuevo la información en el nuevo formato, sin embargo, ante esta situación, Microisis y Winisis dispone de un recurso denominado "Tabla de Selección de Campos para reformateo".

Wind turbine indirect ice detection and operational analysis

Wind energy is one of the most promising and fast growing sector of energy production. Wind is ecologically friendly and relatively cheap energy resource available for development in practically all corners of the world (where only the wind blows). Today wind power gained broad development in the Scandinavian countries. Three important challenges concerning sustainable development, i.e. energy security, climate change and energy access make a compelling case for large-scale utilization of wind energy. In Finland, according to the climate and energy strategy, accepted in 2008, the total consumption of electricity generated by means of wind farms by 2020, should reach 6 - 7% of total consumption in the country [1]. The main challenges associated with wind energy production are harsh operational conditions that often accompany the turbine operation in the climatic conditions of the north and poor accessibility for maintenance and service. One of the major problems that require a solution is the icing of turbine structures. Icing reduces the performance of wind turbines, which in the conditions of a long cold period, can significantly affect the reliability of power supply. In order to predict and control power performance, the process of ice accretion has to be carefully tracked. There are two ways to detect icing – directly or indirectly. The first way applies to the special ice detection instruments. The second one is using indirect characteristics of turbine performance. One of such indirect methods for ice detection and power loss estimation has been proposed and used in this paper. The results were compared to the results directly gained from the ice sensors. The data used was measured in Muukko wind farm, southeast Finland during a project 'Wind power in cold climate and complex terrain'. The project was carried out in 9/2013 - 8/2015 with the partners Lappeenranta university of technology, Alstom renovables España S.L., TuuliMuukko, and TuuliSaimaa.

A satisfação dos clientes internos e o comprometimento organizacional: um estudo à luz do modelo ASH nas indústrias alimentícias do RN

Currently the organizations are passing for continuous cycles of changes due to necessity of survival in the work market. The administration of the future points a way to the organizations of today and tomorrow, the search of the competitiveness from loyalty and motivation of its staff. Of this form, the model of the Auditoria do Sistema Humano (ASH), developed for Spanish researchers and that now it is being applied in Brazil, contemplates a series of dimensions about Human Resources management quality in the companies and the organizational effectiveness, such as the environment where the company is inserted, the strategies, the organizational drawing, the psychological and psychosocial processes, e the reached results. In this direction, the present research analyzed the factors of job satisfaction and organizational commitment, making, also, a relation of causality between the same ones. The quantitative-descriptive research had as population the employees of twenty three nourishing industries of the State of Rio Grande do Norte (Brazil), registered in the Federacy of the Industries of the state. The collection of the data occurred for the months of October of 2005 and March of 2006, by means of the application of questionnaire of model ASH. The sample was composed for 197 employees, however it was observed presence of five outliers, that they had been excluded from the analysis of the data. To extract the dimensions of the satisfaction and the commitment and identification the factorial analysis was used, with extraction method of principal components, rotation Varimax and normalization Kaiser. The gotten dimensions had been evaluated with the calculation of the coefficient Alpha of Cronbach. The factorial analysis of the pointers of the organizational commitment and identification had extracted ten factors. Of these, four had gotten significance of the analyses inside: affective commitment, values commitment, continuance commitment and necessity commitment. The result of the analysis of the pointers of job satisfaction indicated four factors: extrinsic, motivations, relation with the friends and auto-accomplishment. To deal with the data the relation between job satisfaction and organizational commitment it was used technique of multiple regression. The correlation between commitment and satisfaction was satisfactory, detaching the affective commitment with bigger index of correlation, followed of the affective one

Antioxidants attenuate hyperglycaemia-mediated brain endothelial cell dysfunction and blood–brain barrier hyperpermeability

Aims: Hyperglycaemia (HG), in stroke patients, is associated with worse neurological outcome by compromising endothelial cell function and the blood–brain barrier (BBB) integrity. We have studied the contribution of HG-mediated generation of oxidative stress to these pathologies and examined whether antioxidants as well as normalization of glucose levels following hyperglycaemic insult reverse these phenomena. Methods: Human brain microvascular endothelial cell (HBMEC) and human astrocyte co-cultures were used to simulate the human BBB. The integrity of the BBB was measured by transendothelial electrical resistance using STX electrodes and an EVOM resistance meter, while enzyme activities were measured by specific spectrophotometric assays. Results: After 5 days of hyperglycaemic insult, there was a significant increase in BBB permeability that was reversed by glucose normalization. Co-treatment of cells with HG and a number of antioxidants including vitamin C, free radical scavengers and antioxidant enzymes including catalase and superoxide dismutase mimetics attenuated the detrimental effects of HG. Inhibition of p38 mitogen-activated protein kinase (p38MAPK) and protein kinase C but not phosphoinositide 3 kinase (PI3 kinase) also reversed HG-induced BBB hyperpermeability. In HBMEC, HG enhanced pro-oxidant (NAD(P)H oxidase) enzyme activity and expression that were normalized by reverting to normoglycaemia. Conclusions: HG impairs brain microvascular endothelial function through involvements of oxidative stress and several signal transduction pathways.

The transformed-stationary approach: a generic and simplified methodology for non-stationary extreme value analysis

Statistical approaches to study extreme events require, by definition, long time series of data. In many scientific disciplines, these series are often subject to variations at different temporal scales that affect the frequency and intensity of their extremes. Therefore, the assumption of stationarity is violated and alternative methods to conventional stationary extreme value analysis (EVA) must be adopted. Using the example of environmental variables subject to climate change, in this study we introduce the transformed-stationary (TS) methodology for non-stationary EVA. This approach consists of (i) transforming a non-stationary time series into a stationary one, to which the stationary EVA theory can be applied, and (ii) reverse transforming the result into a non-stationary extreme value distribution. As a transformation, we propose and discuss a simple time-varying normalization of the signal and show that it enables a comprehensive formulation of non-stationary generalized extreme value (GEV) and generalized Pareto distribution (GPD) models with a constant shape parameter. A validation of the methodology is carried out on time series of significant wave height, residual water level, and river discharge, which show varying degrees of long-term and seasonal variability. The results from the proposed approach are comparable with the results from (a) a stationary EVA on quasi-stationary slices of non-stationary series and (b) the established method for non-stationary EVA. However, the proposed technique comes with advantages in both cases. For example, in contrast to (a), the proposed technique uses the whole time horizon of the series for the estimation of the extremes, allowing for a more accurate estimation of large return levels. Furthermore, with respect to (b), it decouples the detection of non-stationary patterns from the fitting of the extreme value distribution. As a result, the steps of the analysis are simplified and intermediate diagnostics are possible. In particular, the transformation can be carried out by means of simple statistical techniques such as low-pass filters based on the running mean and the standard deviation, and the fitting procedure is a stationary one with a few degrees of freedom and is easy to implement and control. An open-source MAT-LAB toolbox has been developed to cover this methodology, which is available at https://github.com/menta78/tsEva/(Mentaschi et al., 2016).

Avaliação da contaminação por elementos metálicos dos sedimentos do Estuário Santos - São Vicente

Three approaches were applied to evaluate metal contamination in 41 sediment samples from the Santos - São Vicente Estuarine System: normalization to Al, statistical analysis and sediment quality guidelines (SQGs). The results showed increases in the concentrations of Zn, Ni, Pb, Cd, Cr and Hg, which seemed to be associated with human activities. The levels of Al, Fe and Co probably were associated with crustal material or natural weathering processes. About 45% of the samples presented concentrations exceeding TEL-ERL, levels occasionally associated with adverse biological effects. Four of these samples presented concentrations above PEL-ERM, levels frequently associated with adverse biological effects.

Parcellation of fMRI datasets with ICA and PLS: a data driven approach

Inter-subject parcellation of functional Magnetic Resonance Imaging (fMRI) data based on a standard General Linear Model (GLM) and spectral clustering was recently proposed as a means to alleviate the issues associated with spatial normalization in fMRI. However, for all its appeal, a GLM-based parcellation approach introduces its own biases, in the form of a priori knowledge about the shape of Hemodynamic Response Function (HRF) and task-related signal changes, or about the subject behaviour during the task. In this paper, we introduce a data-driven version of the spectral clustering parcellation, based on Independent Component Analysis (ICA) and Partial Least Squares (PLS) instead of the GLM. First, a number of independent components are automatically selected. Seed voxels are then obtained from the associated ICA maps and we compute the PLS latent variables between the fMRI signal of the seed voxels (which covers regional variations of the HRF) and the principal components of the signal across all voxels. Finally, we parcellate all subjects data with a spectral clustering of the PLS latent variables. We present results of the application of the proposed method on both single-subject and multi-subject fMRI datasets. Preliminary experimental results, evaluated with intra-parcel variance of GLM t-values and PLS derived t-values, indicate that this data-driven approach offers improvement in terms of parcellation accuracy over GLM based techniques.

Os processos de normalização e desenvolvimento da doutrina militar combinada nas Forças Armadas Portuguesas

O emprego das Forças Armadas Portuguesas em Operações Conjuntas e Combinadas faz-se no âmbito do quadro de alianças de que Portugal faz parte, das quais destacamos a Organização do Tratado do Atlântico Norte. No sentido de melhorar a eficácia operacional, a normalização assume um papel fundamental para que se possa atingir a interoperabilidade entre as forças da Aliança. Assim, este trabalho teve como objetivo principal, analisar e sintetizar os processos de normalização e desenvolvimento de doutrina Militar Conjunta e Combinada nas Forças Armadas Portuguesas. Tem ainda como finalidade, identificar lacunas nos processos nacionais, de forma a contribuir para uma melhor integração e harmonização da doutrina da Aliança, tendo em consideração a doutrina nacional e os interesses nacionais. A nossa investigação baseou-se num raciocínio hipotético-dedutivo, apoiado por uma estratégia qualitativa. O modelo de análise desenvolvido teve por hipóteses, que foram deduzidas de questões derivadas da questão central. Neste processo analítico, identificámos indicadores que permitiram a validação das hipóteses, para este efeito, recorremos a dois estudos de caso e uma análise SWOT. O desenvolvimento de um plano de ação que permita a integração dos processos analisados constitui o principal contributo desta investigação. A necessidade de criar uma Estrutura Coordenadora de Normalização, primordial para agilizar os procedimentos de normalização entre o Ministério da Defesa Nacional, o Estado-Maior General das Forças Armadas e os Ramos, juntamente, com a criação de um Conselho Superior de Doutrina nas Forças Armadas, que defina as prioridades e orientações gerais para o desenvolvimento de doutrina, constituem os principais resultados desta investigação. Abstract: The use of the Portuguese Armed Forces in Combined and Joint Operations is made within the framework of alliances that Portugal is a member, of which we highlight the North Atlantic Treaty Organization. In order to improve the operational efficiency, standardization plays a key role in achieving the interoperability between the forces of the Alliance. The aim of this study is to analyse and synthesize the standardization and development processes of Combined and Joint Military Doctrine in the Portuguese Armed Forces. Identify gaps in national processes, in order to contribute to a better integration and harmonization of the Alliance Doctrine, taking into account the national doctrine and national interests. Our research was based on a hypothetical-deductive argument, supported by a qualitative strategy. The analysis model developed based on assumptions, deducted from derivatives questions of the central question. In this analytical process, we identify indicators that allowed the validation of hypotheses, to achieve this purpose we used two case studies and resort to a SWOT analysis. The development of an action plan that allows the integration of the analysed processes is the main contribution of this research. The need to create a Standardization Coordination Structure it´s crucial to streamline the procedures of normalization between the Ministry of Defence, the Armed Forces General Joint Staff and the Services, along with the establishment of a Doctrine Supreme Council in the Armed Forces, which set the priorities and guidelines for the development of doctrine. This are the main outputs of this research.

Novas tendências de gestão pública : a implementação de um programa de avaliação e desenvolvimento de competências numa unidade de serviços partilhados

É hoje consensual, entre as várias correntes da gestão, que a obtenção de vantagens competitivas depende em grande medida das estratégias de gestão de recursos humanos. Orientada para os aspectos estratégicos, a gestão por competências surge como uma abordagem capaz de integrar os objectivos das organizações com os objectivos individuais. Simultaneamente, as novas tendências da gestão pública apontam para a necessidade de desenvolver processos conducentes à melhoria contínua dos serviços prestados, introduzindo um maior rigor na informação de gestão. São princípios subjacentes a estas novas tendências a necessidade de redução de custos, o aumento da produtividade, a normalização de processos e sistemas e o desenvolvimento de centros de competência e inovação. Neste trabalho, de natureza essencialmente empírica, pretendemos ilustrar o processo de concepção e implementação de um Programa de Avaliação e Desenvolvimento de Competências que foi desenvolvido para uma Unidade de Serviços Partilhados, no âmbito de uma organização pública. ABSTRACT: lt is actually consensual between several theoretical approaches that the attainment of competitive advantages depends on strategies of human resource management. Guided for strategic aspects, competencies’ management appears as an approach capable of integrating organizations and individual's goals. Simultaneously, the new trends of public administration point out the necessity of developing continuous improvement processes, introducing a higher quality in the management information. The necessity of costs reduction, the increase of the productivity and the normalization of processes and systems, as well the development of competencies centers and innovation, are underlying principles to these new trends. ln this empirical work we intend to illustrate the process of conception and implementation of a Program of Evaluation and Development of Competencies, developed for a Unit of Shared Services, in a public organization.

Experience of a Single Center in NTBC Use in Management of Hereditary Tyrosinemia Type I in Libya

Background: Hereditary Tyrosinemia type I (HTI) is a metabolic disease caused by deficiency of fumarylacetoacetate hydrolase enzyme. Objectives: This study reports beside its clinical and biochemical presentation, the outcome of NTBC [2- (2-nitro-4-trifloro-methylbenzoyl)-1, 3-cyclohexanedion] treatment of the disease and evaluates its biochemical markers in 16 pediatric Libyan patients. Patients and Methods: The diagnosis was based on presence of high tyrosine levels in blood and succinylacetone in urine. Results: The consanguinity rate was 81.2%, the median age at onset, at diagnosis and at starting treatment were 4.5, 8, and 9.5 months respectively. At presentation hepatomegaly, jaundice, rickets and high gamma glutamyl transferase (GGT) were observed in 87.5% of patients. All patients had extremely high alpha fetoprotein (AFP) and high alkaline phosphatase (ALP) levels. Fifteen patients were treated with NTBC, normalization of PT (Prothrombine time) was achieved in average in 14 days. The other biochemical parameters of liver function (transaminases, GGT, ALP, bilirubin and albumin) took longer to improve and several months to be normalized. Survival rate with NTBC was 86.6%. Patients who started treatment in a median of 3 months post onset observed a fast drop of AFP in 90.6% of patients (P = 0.003). Abnormal liver function and rickets were the common presentations, GGT was an early cholestatic sensitive test. ALP was constantly high even in asymptomatic patients. Conclusions: In HT1 a faster dropping of AFP is a marker of good prognosis.

A summative scoring system for evaluation of human kinematic performance

Evaluation of human kinematic performance is essential in rehabilitation and skill assessment. These services are in high demand where the improvements made due to exercises need to be regularly assessed. In some relevant industries there is a need to evaluate their employee capabilities quantitatively for accident compensation and insurance purposes. In particular, these assessments are preferred to be based on more quantifiable measures in a standardized form ensuring accuracy, reliability, ease of use and anywhere anytime information to the clinician. Therefore, it is necessary to have an efficient mechanism for evaluation and assessment of human kinematic movements as the current motion matching and recognition algorithms fall short due to characteristically strict specifications required in numerous health care applications. In this paper, we propose a summative approach using a double integral to define a closeness between two trajectories typically generated by human movement. This approach can be considered as a spatial scoring mechanism in the evaluation of human kinematic performance as well as in movement recognition applications. Several experiments based on computer simulations as well as real data were set up to examine the performance of the proposed approach as a scoring mechanism for the evaluation of human kinematic performances. The results demonstrated better characterization of the movement assessment and motion recognition ability, with a recognition rate of 86.19%, than the currently used methods such as Gaussian mixture models and pose normalization employed in motion recognition tasks. Finally, we use the scoring mechanism to analyze the proximity in human kinematic performance.
