Global existence and asymptotic behavior of the solutions to the 3D bipolar non-isentropic Euler–Poisson equation
Authors: Li Yeping 
Published: April 2016

In this paper, the global existence of smooth solutions for the three-dimensional (3D) non-isentropic bipolar hydrodynamic model is showed when the initial data are close to a constant state. This system takes the form of non-isentropic Euler–Poisson with electric field and frictional damping added to the momentum equations. Moreover, the L2-decay rate of the solutions is also obtained. Our approach is based on detailed analysis of the Green function of the linearized system and elaborate energy estimates. To our knowledge, it is the first result about the existence and L2-decay rate of global smooth solutions to the multi-dimensional non-isentropic bipolar hydrodynamic model.
On fixed points for for alpha–eta–psi-contractive multi-valued mappings in partial metric spaces
Authors: La Rosa Vincenzo , Vetro Pasquale 
Published: April 2016

Recently, Samet et al. introduced the notion of α–ψ-contractive type mappings and established some fixed point theorems in complete metric spaces. Successively, Asl et al. introduced the notion of α*–ψ-contractive multi-valued mappings and gave a fixed point result for these multi-valued mappings. In this paper, we establish results of fixed point for α*-admissible mixed multi-valued mappings with respect to a function η and common fixed point for a pair (S,T) of mixed multi-valued mappings, that is, α*-admissible with respect to a function η in partial metric spaces. An example is given to illustrate our result.

Authors: Danilenko Svetlana , Šiaulys Jonas 
Published: April 2016

Assume that ξ1, ξ2, ... are independent and identically distributed non-negative random variables having the O-exponential distribution. Suppose that η is a nonnegative non-degenerate at zero integer-valued random variable independent of ξ1, ξ2, ... . In this paper, we consider the conditions for η under which the distribution of random sum ξ1 + ξ2 + ... + ξη remains in the class of O-exponential distributions.
Multivariate goodness-of-fit tests based on kernel density estimators
Authors: Bakshaev Aleksej , Rudzkis Rimantas 
Published: April 2016

The paper is devoted to multivariate goodness-of-fit ests based on kernel density estimators. Both simple and composite null hypotheses are investigated. The test statistic is considered in the form of maximum of the normalized deviation of the estimate from its expected value. The produced comparative Monte Carlo power study shows that the proposed test is a powerful competitor to the existing classical criteria for testing goodness of fit against a specific type of an alternative hypothesis. An analytical way to establish the asymptotic distribution of the test statistic is discussed, using the approximation results for the probabilities of high excursions of differentiable Gaussian random fields.

In this paper, we prove some fixed point results involving α-implicit contractions in quasi-metric spaces. Moreover, we provide some known results on G-metric spaces. An example and an application on a solution of a nonlinear integral equation are also presented.
Fixed points for Kannan type contractions in uniform spaces endowed with a graph
Authors: Aghanians Aris , Nourouzi Kourosh 
Published: April 2016

In this paper, we give two sufficient conditions for the existence of a fixed point for a Kannan type contraction in a p-complete separated uniform space endowed with a graph and equipped with an A- or an E-distance p. We also discuss the uniqueness of the fixed point and show that Banach and Kannan type contractions are independent.

Published: April 2016

OBJECTIVE:
The objective was to evaluate a manualized theory-driven primary preventive intervention aimed at early childhood obesity. The intervention was embedded in Swedish child health services, starting when eligible children were 9 to 10 months of age and continuing until the children reached age 4.

METHODS:
Child health care centers in 8 Swedish counties were randomized into intervention and control units and included 1355 families with 1369 infants. Over ∼39 months, families in the intervention group participated in 1 group session and 8 individual sessions with a nurse trained in motivational interviewing, focusing on healthy food habits and physical activity. Families in the control group received care as usual. Primary outcomes were children’s BMI, overweight prevalence, and waist circumference at age 4. Secondary outcomes were children’s and mothers’ food and physical activity habits and mothers’ anthropometrics. Effects were assessed in linear and log-binominal regression models using generalized estimating equations.

RESULTS:
There were no statistically significant differences in children’s BMI (β = –0.11, 95% confidence interval [CI]: –0.31 to 0.08), waist circumference (β = –0.48, 95% CI: –0.99 to 0.04), and prevalence of overweight (relative risk = 0.95, 95% CI: 0.69 to 1.32). No significant intervention effects were observed in mothers’ anthropometric data or regarding mothers’ and children’s physical activity habits. There was a small intervention effect in terms of healthier food habits among children and mothers.

CONCLUSIONS:
There were no significant group differences in children’s and mothers’ anthropometric data and physical activity habits. There was, however, some evidence suggesting healthier food habits, but this should be interpreted with caution.
A Recursive Formula for the Evaluation of Earth Return Impedance on Buried Cables
Authors: Iracheta Reynaldo 
Published: April 2016

<p class="Abstractandkeywordscontent"><span style="font-size: small;"><span style="font-family: Century Gothic;">This paper presents an alternative solution based on infinite series for the accurate and efficient evaluation of cable earth return impedances. This method uses Wedepohl and Wilcox’s transformation to decompose Pollaczek’s integral in a set of Bessel functions and a definite integral. The main feature of Bessel functions is that they are easy to compute in modern mathematical software tools such as Matlab. The main contributions of this paper are the approximation of the definite integral by an infinite series, since it does not have analytical solution; and its numerical solution by means of a recursive formula. The accuracy and efficiency of this recursive formula is compared against the numerical integration method for a broad range of frequencies and cable configurations. Finally, the proposed method is used as a subroutine for cable parameter calculation in the inverse Numerical Laplace Transform (NLT) to obtain accurate transient responses in the time domain.</span></span></p>
High-dynamic range compressive spectral imaging by grayscale coded aperture adaptive filtering
Authors: Diaz Nelson Eduardo , Rueda Chacon Hoover Fabian , Arguello Fuentes Henry 
Published: April 2016

<p class="p1">The coded aperture snapshot spectral imaging system (CASSI) is an imaging architecture which senses the three dimensional informa-tion of a scene with two dimensional (2D) focal plane array (FPA) coded projection measurements. A reconstruction algorithm takes advantage of the compressive measurements sparsity to recover the underlying 3D data cube. Traditionally, CASSI uses block-un-block coded apertures (BCA) to spatially modulate the light. In CASSI the quality of the reconstructed images depends on the design of these coded apertures and the FPA dynamic range. This work presents a new CASSI architecture based on grayscaled coded apertu-res (GCA) which reduce the FPA saturation and increase the dynamic range of the reconstructed images. The set of GCA is calculated in a real-time adaptive manner exploiting the information from the FPA compressive measurements. Extensive simulations show the attained improvement in the quality of the reconstructed images when GCA are employed. In addition, a comparison between traditional coded apertures and GCA is realized with respect to noise tolerance.</p>
Disclosure no serviço público: análise da aplicabilidade da lei de transparência em municípios mineiros
Authors: Miranda Silva Derley Júnior , Segatto Juliane Andrade Costa , Silva Marli Auxiliadora da 
Published: April 2016

Buscou-se, neste estudo descritivo, desenvolvido por meio de análise documental, verificar, mediante o acesso e consulta aos portais eletrônicos, se os atos da Administração Pública de 30 (trinta) municípios do estado de Minas Gerais, com população acima de 100 (cem) mil habitantes, relativamente à execução financeira e orçamentária, atendem ao disposto na Lei Complementar nº 131/2009, Lei de Transparência, verificando também o disclosure desses municípios. Em todos os 30 (trinta) municípios mineiros investigados constatou-se a implantação da Lei de Transparência. A totalidade de municípios possui portais eletrônicos. Todavia essa implantação não evidencia o disclosure e não atende totalmente aos requisitos legais obrigatórios e recomendados para a evidenciação da execução orçamentária. Em alguns websites as informações são de difícil visualização. É necessária a abertura de vários links até o acesso à informação desejada. Confirmou-se, ainda, no período de consulta aos portais, que municípios com expressiva densidade populacional, como Uberlândia, Contagem, Juiz de Fora e Montes Claros, lideram a lista dos que atenderam a um número menor de critérios definidos legalmente. O município de Ribeirão das Neves é o que mais atende aos requisitos legais de transparência, seguido pelos municípios de Ipatinga e Teófilo Otoni. Observou-se, ainda, que alguns sítios eletrônicos apresentam períodos constantes de manutenção permanecendo indisponíveis ou desativados por longos espaços de tempo prejudicando o acesso dos cidadãos e dificultando o acompanhamento de informações disponibilizadas em tempo real pelos agentes públicos.
Measuring outputs, neglecting outcomes: The Auditor General’s role in SAPS performance assessments
Authors: Bruce David 
Published: April 2016

Performance monitoring, often based on the use of performance indicators, has become a central aspect of the work of government departments in South Africa. Even though the South African Police Service (SAPS) is regarded as one of the leading government departments in the use of performance monitoring systems, it does not use performance information in a critical enough manner, particularly given the risk that the introduction of performance measures will lead to perverse incentives. Given that the SAPS is one of the largest police services in the world, the centralised reporting on organisational performance in the annual report is ineffective. It obscures much more than it reveals about what is being achieved by the organisation. Since 2005 the Auditor General of South Africa has been phasing in a ‘predetermined objectives’ audit that involves checking on the reliability of the performance information presented by the SAPS. Though he has limited capacity to do so, the AG also carries out what are called ‘performance audits’, that involve deeper and more focused scrutiny of the functioning of government departments. A 2008-09 performance audit on service delivery at police stations and 10111 call centres highlights the type of scrutiny that the SAPS needs to be subjected to if information on its performance is to become more meaningful.
Building a Common Vision of the Local Development using a Methodology Called Participatory Territorial Planning
Authors: De Caro A. A. , Mérida Moisés Augusto 
Published: April 2016

Abstract
Petróleos de Venezuela SA (PDVSA) is a state owned company which has boosted its social investments since 2003. In spite of this, it has established a territorial development department with the purpose of moving forward from social responsibility to a new philosophy called social integration. Social integration means not only working together with communities and local authorities, but also building together a common vision of local development. The common vision on the development of a particular territory arises from a dialogue among the visions of local communities, authorities and technicians, including employees of PDVSA.
This common vision is a image of the future of a particular territory accompanied by a plan. The development plan is the collective result in which not only the benefits of the business plan of oil and gas are incorporated, but also including actions to mitigate risks, and those projects and programs needed to reduce social conflicts and to establish a win-win relationship among all actors.
The final participatory development plan is a broad consensus achieved step by step. Participatory territorial planning is a group of sequential techniques by which any person or interest group in a particular territory can jointly assess it. This methodology designed consists of five phases and nine stages.
The five phases of the methodology are: Local assessment; Territorial development plan; Participatory budget; Execution; and Social control and feedback. Most phases include participatory mapping workshops in which participants reach agreements using maps. A toolbox has been defined in order to present a resume of techniques and methods that are used during the implementation of the participatory territorial planning.
A participatory development plan works as a roadmap. This type of plans integrate efficiently projects and programs planned by local inhabitants; non-governmental organizations; authorities; and energy companies. The novelty of the proposal is the definition of a new methodology that makes the inhabitants as promoters of sustainable cities and they start sharing the vision of energy companies about local development. In addition, resources for communities are invested more efficiently and the staff of energy companies can grasp their local context much better.
A Joint Strategy Between the Hydrocarbon Sector and Colombian Environmental Authorities for the Conservation of a Regional Natural Park
Authors: Carmona Luis Gabriel , Correa Fernando , Perdomo Karin 
Published: April 2016

Abstract
Companies involved in water and forest resource extraction in Colombia are obliged to compensate for any resulting impacts stemming from their activities, as agreed with the environmental authorities. Compensation usually relates to reforestation or the development of public service infrastructure. However, these initiatives should be more relevant to the local community and ensure that the protection of biodiversity is efficiently undertaken and optimized to support the greatest number of benefits to fauna and flora and the provision of ecosystem services. This paper shows how a partnership between Mansarovar Energy Colombia Ltd., a heavy oil extraction company, and the national and local environmental authorities, resulted in the establishment of buffer zones to support the conservation of the Regional Natural Park "Serranía de las Quinchas". In total one thousand hectares were added to the already existing 21,000 ha that legally constitute the park. This synergy led to a greater impact within the local community, compared to when each entity worked separately.
Alkyl Aryl Sulfonates Surfactants For EOR: Scale Up From Lab To Pilot
Authors: Aguilar Francisco , López Ignacio , Prieto Carlos , Montes Jesús , Lázaro Jesús , Barrio Izaskun , Álvarez Estefanía , Rodriguez Borja 
Published: April 2016

Abstract
Scaling up from lab to pilot is one of the challenges to meet in any ASP project to accomplish the requirements at full implementation. Tailored EOR surfactants developed and manufactured in the laboratory, to achieve the lowest interfacial tension (IFT) between oil and water at the reservoir conditions, have to be viable and robust in the manufacture, capable in performance and compatible in the formulation, not only at laboratory scale, but also at industrial scale.
It is described in this poster the route map in the development and manufacture of alkyl aryl sulfonates surfactants for the Cepsa ASP pilot project in the Caracara Sur field, Los Llanos basin (Colombia) from a continuous feed-back of the laboratory tests. The surfactant employed for the project was selected from other surfactants from several suppliers and dyalkylbenzene sodium sulfonate was the one achieving the lowest interfacial tension for Caracara field conditions. The dyalkylbenzene sodium sulfonate was accompanied by a co-surfactant improving the solubility and performance properties.
Pilot ASP injection started in May 2015 and some conclusions were obtained during the production of the surfactants in several manufacture batches: Composition, molecular weight even isomerism of alkylbenzenes may impact strongly on the interfacial activity of alkyl aryl sulfonates surfactants.Sulfonation and neutralization of alkylbenzenes are critical processes to comply the requirements of alkyl aryl surfactants for any cEOR project.Finally, the laboratory in the field for quality assurance and quality control (QA/QC) of surfactants is completely necessary. Periodical sampling and on-site analyses are scheduled but also samples delivery to research center for more sophisticated analyses. These data are essential for the final performance evaluation and the project success.
A methodology for linking 2D overland flow models with the sewer network model SWMM 5.1 based on dynamic link libraries
Authors: Leandro Jorge , Martins Ricardo 
Published: April 2016

Abstract
Pluvial flooding in urban areas is characterized by a gradually varying inundation process caused by surcharge of the sewer manholes. Therefore urban flood models need to simulate the interaction between the sewer network and the overland flow in order to accurately predict the flood inundation extents. In this work we present a methodology for linking 2D overland flow models with the storm sewer model SWMM 5. SWMM 5 is a well-known free open-source code originally developed in 1971. The latest major release saw its structure re-written in C ++ allowing it to be compiled as a command line executable or through a series of calls made to function inside a dynamic link library (DLL). The methodology developed herein is written inside the same DLL in C + +, and is able to simulate the bi-directional interaction between both models during simulation. Validation is done in a real case study with an existing urban flood coupled model. The novelty herein is that the new methodology can be added to SWMM without the need for editing SWMM's original code. Furthermore, it is directly applicable to other coupled overland flow models aiming to use SWMM 5 as the sewer network model.

Abstract
In recent years, employing radiation technology is gaining great interest in degradation of industrial effluents. In this work the possibility of using gamma irradiation to degrade Reactive Red 120 (C.I.292775) was explored. The effects of pH, dose of gamma irradiation and concentration of dye were examined and their interaction were also established based on their response. For the analysis and optimisation of variables, three factor three level Box-Wilson face centred central composite design (CCF) was used. Analysis of variance with R2 = 0.9988, adjusted R2 = 0.9981 and the adequate precision value of 122.303 indicates that the CCF model can be used. The coefficient of variation (0.54%) indicates the reliability of the model. The dose of gamma irradiation (kGy) and the concentration of dye (mg/L) showed significant effects on the degradation of RR 120, while a difference of 6 to 10% degradation was observed in extending the pH towards the acid or alkali range from pH 7.00. The maximum concentration of dye degraded was observed as 347.509 mg/L at initial pH: 7.0, dose of gamma irradiation: 5.94 kGy and initial concentration of dye: 500 mg/L. This predicted value was found to be in agreement with the experimental value on the optimised conditions.
HIV Infection and AIDS in Sub-Saharan Africa: Current Status, Challenges and Opportunities
Authors: Kharsany Ayesha B.M. , Karim Quarraisha A. 
Published: April 2016

Global trends in HIV infection demonstrate an overall increase in HIV prevalence and substantial declines in AIDS related deaths largely attributable to the survival benefits of antiretroviral treatment. Sub-Saharan Africa carries a disproportionate burden of HIV, accounting for more than 70% of the global burden of infection. Success in HIV prevention in sub-Saharan Africa has the potential to impact on the global burden of HIV. Notwithstanding substantial progress in scaling up antiretroviral therapy (ART), sub-Saharan Africa accounted for 74% of the 1.5 million AIDS related deaths in 2013.
Of the estimated 6000 new infections that occur globally each day, two out of three are in sub-Saharan Africa with young women continuing to bear a disproportionate burden. Adolescent girls and young women aged 15-24 years have up to eight fold higher rates of HIV infection compared to their male peers. There remains a gap in women initiated HIV prevention technologies especially for women who are unable to negotiate the current HIV prevention options of abstinence, behavior change, condoms and medical male circumcision or early treatment initiation in their relationships.
The possibility of an AIDS free generation cannot be realized unless we are able to prevent HIV infection in young women. This review will focus on the epidemiology of HIV infection in sub-Saharan Africa, key drivers of the continued high incidence, mortality rates and priorities for altering current epidemic trajectory in the region. Strategies for optimizing the use of existing and increasingly limited resources are included.
Que reste-t-il de l'industrie après la désindustrialisation ? De la négation au patrimoine industriel. (What remains after deindustrialization ? From dereliction and denial to industrial heritage)
Authors: Edelblutte Simon 
Published: April 2016

Deindustrialization is real in Western Europe and so in France. However, it's never complete, because industry is still present, first with innovative fields and second through the signs and marks let by closed factories.
Based on the idea of a progressive deindustrialization, this work aims first to identify theses signs, sometimes spectacular such as abandoned factories, more often quiet such as workers' houses. Second, this paper deals with the negation period which follows the closure of factories. This period is considered as a mourning time. Finally, it focuses about the recent and growing development in France of industrial heritage, which preserves remains of industry after the crises.
