Published: August 2017

Es de gran importancia conocer cuáles son las causas para que se presenten sags en las barrajes de distribución, debido a que la afectación sobre los clientes industriales es de carácter relevante. Por esta razón se planteó una metodología para buscar la correlación existente entre sags y los eventos ambientales u operativos del sistema de distribución. A manera de ejemplo, se aplicó en tres subestaciones, las cuales se encuentran ubicadas en diferentes sectores de la ciudad. Para el desarrollo de esta metodología, se realizó la correlación de los datos mediante la implementación de tablas dinámicas y programación en Access, donde se evidenció qué tipo de eventos son los que tienen un mayor impacto sobre los clientes. De acuerdo a los resultados obtenidos se sugiere algunas recomendaciones para mitigar este tipo de eventos en el sistema de distribución.

Abstract
Platinum(II) and vanadium(V) solid binary and ternary complexes involving naringin, a flavanone glycoside in found in grapefruit, and some phenolic acids were synthesized and fully characterized using detailed structural and spectroscopic analysis techniques such as IR, NMR, and SEM techniques. The magnetic susceptibility results as well line drawings of the platinum and vanadium complexes showed four-coordinate square-planar and remarkable low-spin diamagnetic species; which is in agreement with the structures proposed. The cytotoxic activities of the binary and ternary vanadium and platinum metal complexes of phenolic acids and naringin were tested and evaluated against HepG2 (human hepatocellular carcinoma), MCF-7 (human breast adenocarcinoma), and HCT116 (human colorectal carcinoma) tumor cell lines. Also, their antioxidant activities were examined by free radical scavenging assay. The relationship between the chemical structure of the synthesized complexes and their biological influence was studied and evaluated.

Published: August 2017

Abstract
Allantoic cysts of the umbilical cord are embryological remnants of either the allantois or the omphalomesenteric duct. These cysts represent a rare ultrasound finding especially in the first trimester. Allantoic cysts can be associated with fetal malformations and chromosomal aberrations or are characterised by spontaneous resolution and good pregnancy outcome. Here we present a rare case of umbilical cord cyst detected by ultrasound in the first trimester with later resolution and favourable pregnancy outcome.
Considering spectral variability for optical material abundance estimation
Authors: Krippner Wolfgang , Bauer Sebastian , Puente León Fernando 
Published: August 2017

Abstract
Hyperspectral images include information enabling the determination of material abundances. Due to the fact that the acquisition of hyperspectral images is time consuming and the processing of these images is computationally costly, we propose an optical approach using spectral filters to retrieve the material abundances. The application of a spectral filter leads to an intensity image encoding estimates for the abundances of a specific material. The acquisition and processing of hyperspectral images becomes superfluous. However, the determination of spectral filters offers a large degree of freedom. In this work, we focus on methods for designing spectral filters incorporating spectral variability. Particularly, we account for reducing the negative effects of spectral variability on the accuracy of estimates for material abundances. According to experimental evaluations, we conclude that including spectral variability into the calculation of spectral filters leads to more accurate abundance estimates when mixed spectra of the considered material mixtures sufficiently fulfill the linear mixing model.

<p><span>A aglomeração geográfica de serviços é tema pouco explorado na literatura brasileira. Os estudos realizados partem de critérios de classificação que não refletem a diversidade do setor de serviços bem como a interação deste com as atividades de indústria. Diante disso, o objetivo deste artigo foi realizar um mapeamento da localização das atividades de serviço na região Sudeste do Brasil de maneira sistemática, baseado numa proposta de classificação dos serviços de acordo com o processo econômico ao qual estão relacionados. Sendo assim, a principal contribuição deste artigo é uma metodológica classificatória. Propõe-se um modelo de classificação das aglomerações de acordo com as categorias de serviço puro, de transformação e de troca e circulação. Foi identificado um total de 12.201 aglomerados de serviços no Brasil; a maioria (60%) refere-se à categoria de serviço puro, seguido da categoria de serviços de troca e de circulação, com (27%), e serviços de transformação, com (13%). Sob a perspectiva das macrorregiões, a região sudeste possui a maior representatividade, com um total de 5.287 aglomerações, representando 43% do total das aglomerações. Nesta região, as três categorias de serviço apresentam participação significativa, ao contrário das demais regiões, o que confirma o elevado grau de desenvolvimento da base econômica da região, uma vez que quanto maior a composição dos setores, mais desenvolvida é a economia local. Neste sentido, as principais descobertas deste estudo explicam a força econômica das atividades de serviço nas regiões sudeste do país, com destaque para os grandes centros urbanos, como São Paulo e Rio de Janeiro.</span></p>

The study entitled, "The implementation of the retroactive principle in fighting against corruption". The background of this research was derive from the fact that corruption is an extraordinary crime that needs an extra way against it. The formation of Corruption Eradication Commission (KPK) as an independent agency in the form of eradicating corruption in Indonesia has gradually demonstrated its role. But, Problems then occur when the citizen force KPK to handle the corruption cases before this constitution constructed, especially BLBI case which made this state inflict a financial loss about Rp 138,4 trillions happen during the 1997-1998. From the background it raised an issue, whether the retroactive principle can be applied by the Commission in the investigation, and prosecution of the perpetrators of corruption that occurred before the enactment of Law No. 30 Year 2002 was made on the Corruption Eradication Commission? In this discussion the retroactive principle can be applied by the Commission in making "a series of actions" which make it able to conduct an investigation and prosecution of the perpetrators of corruption despite they occurred before Law. 30 of 2002 on the Corruption Eradication Commission enacted. Besides confirming that the application of this principle is that corruption is a crime classified as an extraordinary crime which has wide negative effects to the country.

This research is based on a gap that happened in arranging tour guides in Bali in which there are norms conflict between the regional regulation of Bali Province Number 5 Year 2008 on Tour Guide and the Regulation of Cultural and Tourism Minister Number: PM.92/HK.501/MKP/2010 on The Registration Procedure of Tour Guides Business which causes the Government of Bali Province doubtful in doing the authority of controling. In this research is discussed two problem namely the authority of Bali Province Government in arranging the tour guides business and controlling the tour guides. From the research which is conduct with statute approach and the law concept analysis approach that is analyzed by systematization, evaluation, argumentation and description method, it is known that the Bali Province Government has attribution authority which is strict for arranging the tour guides business and this matter implies on the authority to conduct control that includes law and administration, technical ability and tour guides behavior. Since regional regulation made by the autonomous government structure with autonomous autorithy then the regulation that arranges specified authority for that region remains valid.

Multiple linear regression analysis with a lot of independent variable always makes many problems because there is a relationship between two or more independent variables. The independent variables which correlated each other are called multicollinearity. Principal component analysis which based on variance covariance matrix is very sensitive toward the existence of outlier in the observing data. Therefore in order to overcome the problem of outlier it is needed a method of robust estimator toward outlier. ROBPCA is a robust method for PCA toward the existence of outlier in the data. In order to obtain the robust principal component is needed a combination of Projection Pursuit (PP) with Minimum Covariant Determinant (MCD). The results showed that the ROBPCA method has a bias parameter and Mean Square Error (MSE) parameter lower than Principal Component Regression method. This case shows that the ROBPCA method better cope with the multicollinearity observational data influenced by outlier.

Multicollinearity is a problem that often occurs in multiple linear regression. The existence of multicollinearity in the independent variables resulted in a regression model obtained is far from accurate. Latent root regression is an alternative in dealing with the presence of multicollinearity in multiple linear regression. In the latent root regression, multicollinearity was overcome by reducing the original variables into new variables through principal component analysis techniques. In this regression the estimation of parameters is modified least squares method. In this study, the data used are eleven groups of simulated data with varying number of independent variables. Based on the VIF value and the value of correlation, latent root regression is capable of handling multicollinearity completely. On the other hand, a regression model that was obtained by latent root regression has value of 0.99, which indicates that the independent variables can explain the diversity of the response variables accurately.

Published: August 2017

BACKGROUND: Interaction of von Willebrand factor (VWF) with circulating platelets is the trigger for thrombosis in a region of arterial stenosis. These events are typically studied in vitro under conditions where platelets adhere to a VWF-coated surface. Our approach assesses platelet responses in the absence of adhesion. OBJECTIVE: To characterize extent of platelet activation and erythrocyte lysis in an artificial stenosis model. METHODS: Whole blood is perfused through a length of polyetheretherketone tubing that includes an artificial stenosis, comprising narrow-bore (89–381 μm) tubing. Secretion of [14C] serotonin and hemoglobin release was measured to evaluate platelet activation and hemolysis respectively at various perfusion rates and different stenosis dimensions. RESULTS: Platelet activation and erythrocyte lysis increased progressively with increasing perfusion rate and decreasing stenosis diameter; the length of the stenosis had negligible influence. Modest platelet activation (5–10% secretion of [14C] serotonin) occurred without significant erythrocyte lysis under a limited range of perfusion conditions (4–6 mL/min flow through a 127 μm stenosis). CONCLUSIONS: Our experimental approach mimics conditions in severe arterial stenosis or a mechanical heart valve. It could be a valuable aid in the development of novel drugs to treat arterial thrombosis and in the design of heart valves.

Published: August 2017

BACKGROUND: Tissue channels as a part of microcirculation system have been proposed over three decades, playing an important role in fluid transportation as reported. Adventitia of inferior vena cava (IVC) is a typical hierarchical porous media with abundant tissue channels. Its fluid transportation behaviors attract massive research interest. However, the mechanism of the driving force and microstructure was lack of deep research. OBJECTIVE: This study was to investigate the microstructural basis of fluid transportation within inferior vena cava (IVC). METHODS: Rat IVC samples were extracted and fixed on a gelatin substrate. Four samples were randomly used as 4 cases: Case 1 with AFM loading and the fluorescent tracer adding; Case 2 with fluorescent tracer adding only; Case 3 with AFM loading only as the control group; Case 4 with no treatment. The movement of fluorescent tracer was observed by two-photon fluorescent microscope and analyzed by self-made Matlab program. The microscopic structure was characterized by high resolution TEM. RESULTS: The fluorescent tracer in Case 1 exhibited faster and longer transportation comparing to other cases, while in Case 2 diffused normally following Fick’s law. Case 3 with only AFM loading demonstrated that collagen bundles twisting along the fluid orientation, while the bundles in Case 4 with no treatment were straggling. The brush-like macromolecule structure of collagen microfibril was found on the bundle surfaces under TEM. CONCLUSIONS: Transportation within loose connective tissues is observed ex vivo. AFM loading, as the mechanical stimulation resemblance to muscle constrictions and blood pulsations, can facilitate the transportation as the driving force. The brush-like glycosaminoglycan macromolecules on the surfaces of the collagen bundles can be considered as a type of hierarchical porous media, which might form the transport pathway for fluids. The possible mechanism was conducted regarding the conformation of the superficial macromolecule brushes.
Self-gravity in Magnetized Neutrino-dominated Accretion Disks
Authors: Shahamat Narjes , Abbassi Shahram 
Published: August 2017

Abstract
In the present work we study self-gravity effects on the vertical structure of a magnetized neutrino-dominated accretion disk as a central engine for gamma-ray bursts (GRBs). Some of the disk physical timescales that are supposed to play a pivotal role in the late-time evolutions of the disk, such as viscous, cooling, and diffusion timescales, have been studied. We are interested in investigating the possibility of the occurrence of X-ray flares, observed in late-time GRBs’ extended emission through the “magnetic barrier” and “fragmentation” processes in our model. The results lead us to interpret self-gravity as an amplifier for Blandford–Payne luminosity (BP power) and the generated magnetic field, but a suppressor for neutrino luminosity and magnetic barrier processes via highlighting the fragmentation mechanism in the outer disk, especially for the higher mass accretion rates.
Kinetic Scale Structure of Low-frequency Waves and Fluctuations

Published: August 2017

Abstract
The dissipation of solar wind turbulence at kinetic scales is believed to be important for the heating of the corona and for accelerating the wind. The linear Vlasov kinetic theory is a useful tool for identifying various wave modes, including kinetic Alfvén, fast magnetosonic/whistler, and ion-acoustic (or kinetic slow), and their possible roles in the dissipation. However, the kinetic mode structure in the vicinity of ion-cyclotron modes is not clearly understood. The present paper aims to further elucidate the structure of these low-frequency waves by introducing discrete particle effects through hybrid simulations and Klimontovich formalism of spontaneous emission theory. The theory and simulation of spontaneously emitted low-frequency fluctuations are employed to identify and distinguish the detailed mode structures associated with ion-Bernstein modes versus quasi-modes. The spontaneous emission theory and simulation also confirm the findings of the Vlasov theory in that the kinetic Alfvén waves can be defined over a wide range of frequencies, including the proton cyclotron frequency and its harmonics, especially for high-beta plasmas. This implies that these low-frequency modes may play predominant roles even in the fully kinetic description of kinetic scale turbulence and dissipation despite the fact that cyclotron harmonic and Bernstein modes may also play important roles in wave–particle interactions.
As Dinâmicas nas Políticas de Ensino Superior - Um Modelo Teórico
Authors: Kauko Jaakko 
Published: August 2017

Este artigo apresenta um modelo para analisar as dinâmicas nas políticas de ensino superior (DHEP). Teoricamente, o modelo baseia-se na história conceitual da contingência política, das teorias do agendamento (agenda setting) e em pesquisas anteriores sobre o assunto. De acordo com o modelo, a complexidade sócio-histórica pode ser melhor analisada considerando-se duas dimensões: a situação política e as possibilidades políticas. Empiricamente, o modelo foi testado e desenvolvido no contexto do ensino superior finlandês, por meio de entrevistas e de material documental, cujos resultados tornaram possível identificar que as dinâmicas nas políticas de ensino superior estão fortemente relacionada a mudanças externas ao sistema de ensino superior, posições mutáveis dos atores em diferentes vertentes políticas e à natureza inesperada das dinâmicas. As DHEP também podem ser usadas para desvelar os efeitos das possibilidades estabelecidas, porém implícitas, que podem viabilizar ou impossibilitar outras vertentes políticas em um sistema de ensino superior.

Purpose Extracorporeal life support (ECLS) is a cardiopulmonary support system used for the treatment of severe cardiac and/or respiratory failure. Mortality is high partly because of the severity of the condition that requires support. The use of ECLS is generally associated with heavy sedation. The aim of this study was to demonstrate the feasibility of stopping sedation, allowing extubation of patients supported by ECLS. Methods 196 patients supported by ECLS for a period of 4 years were included. Sedation was stopped as soon as possible to allow extubation. The 44 extubated patients were compared with non-extubated patients. Finally, 24% of patients were not extubated without a determined cause and were compared with extubated patients. Results The extubated patients had a lower incidence of ventilator-associated pneumonia. In a multivariate analysis, the independent risk factors for death were the duration of ECLS, age and lack of extubation. Stopping sedation and extubation are feasible in selected patients under ECLS. Conclusions This strategy could be a survival factor.
