Modeling, Simulation and Analysis of Disturbances and Defects in Low Voltage Instalations

Abstract In this article we present some simulation models regarding the occurences that affect the quality of the electricity supplied to a low voltage consumer. We believe that these will offer to the researcher the opportunity to simulate power quality deviations in different energy system models, thus providing a picture regarding the way those deviations propagate and behave, creating a few basic patterns for studying the energy quality, also taking into consideration the limitations of the system in respect to the software used and the human factor performing the research.
Optimization method for sequential determination of Cu and Fe in airborne particulate matter collected on glass fiber filters by slurry sampling FAAS

Um metodo para determinacao sequencial de Cu e Fe em material particulado atmosferico (APM) coletado em filtro de fibra de vidro por amostragem em suspensao e espectrometria de absorcao atomica com chama e proposto. A otimizacao do metodo foi realizada utilizando-se uma massa de amostra seca em po (filtro + APM) de 50 mg, dispersa em solucao de acido nitrico 0,5 mol L-1 e tratada por 10 min em banho ultrassonico. Os limites de deteccao (n = 10) foram 4 e 14 µg g-1 para Cu e Fe no filtro, respectivamente. A repetitividade expressa como desvio padrao relativo foi melhor do que 7 e 8% (n = 3) para Cu e Fe, respectivamente. A exatidao do metodo foi confirmada analisando-se material de referencia certificado de cinzas atmosfericas (BCR 176R). Os resultados obtidos para seis amostras de APM utilizando o metodo proposto nao apresentaram diferencas significativas em comparacao com os valores obtidos usando o metodo de extracao acida e determinacao por espectrometria de massas com plasma indutivamente acoplado. O metodo analitico mostrou-se simples, rapido e confiavel.
Generic object detection in maritime environment using self-resemblance

We propose a novel unified framework for the initial detection of possible targets within the aerial images using saliency detection. Our method is a bottom-up approach and computes Locally Adaptive Regression Kernel (LARK) from the given image, which measures the likeness of a pixel to its surroundings. Visual saliency is then computed using the self-resemblance measure. The framework results in a saliency map and each pixel indicates the statistical likelihood of saliency of a feature matrix given its surrounding feature matrices. As a similarity measure, matrix cosine similarity is employed. State of the art performance is demonstrated on real aerial images.
Coverage boundary of unknown environment using mobile sensor networks

In this article, we consider the problem of optimal coverage of unknown environmental boundary using sensor networks. Since the boundary is unknown to all sensors, it is necessary for the sensors to find it first. We give a new distributed estimate policy by tracking a virtual agent using the sensor networks. Then we consider the problem of optimal coverage of the estimate boundary instead of the actual one. Moreover, an algorithm is given to deploy the sensors to the optimal configuration corresponding to the coverage problem considered in this article.
Unimodal kernel density estimation by datra sharpening

We discuss a robust data sharpening method for rendering a standard kernel estimator, with a given bandwidth, unimodal. It has theoretical and nu- merical properties of the type that one would like such a technique to enjoy. In particular, we show theoretically that, with probability converging to 1 as sample size diverges, our technique alters the kernel estimator only in places where the lat- ter has spurious bumps, and is identical to the kernel estimator in places where that estimator is monotone in the correct direction. Moreover, it automatically splices together, in a smooth and seamless way, those parts of the estimator that it leaves unchanged and those that it adjusts. Provided the true density is unimodal our estimator generally reduces mean integrated squared error of the standard kernel estimator.
The attitudes of primary school children to breastfeeding and the effect of health education lectures.

OBJECTIVE To assess attitudes to breastfeeding among children in primary education and to evaluate the influence of educational lectures on their knowledge. METHODS This was a cross-sectional study of 503 students of both sexes from the fourth to the eighth grades of five different schools. The children were divided into two groups: control (n = 215) and intervention (n = 288) in order to evaluate the influence of educational lectures. A questionnaire containing 30 questions about different features of breastfeeding was used for data collection. The intervention took the form of a 30-minute lecture, given at the schools. RESULTS The lecture increased the number of schoolchildren who answered that breastmilk is most beneficial for infants (p < 0.05) and that breastfeeding is the most practical way of feeding babies (p < 0.05). There was a reduction in the number who would give supplementary feeding during the first month of life (p < 0.05) and also in how many would give a baby a pacifier (p < 0.05). After the intervention less than half of the girls would chose to breastfeed for 1 year or more (39.1% in the control group vs. 43.2% in the intervention group); while the opposite was true of the males (54.7% in the control group vs. 51.7% in the intervention group). More of the boys (37.1%) were able to cite specific advantages for mothers from breastfeeding when compared to the females (19.9%). CONCLUSIONS The results indicate that lectures on health education, presented at schools, have a beneficial effect on breastfeeding knowledge, awareness and attitudes.
Character segmentation on traffic panels using visual appearance from roadside imagery

Segmentation of text on traffic panels has shown great importance. Detection and recognition of traffic panels text is still a challenge in computer vision due to its different types and hug asymmetric information. This paper proposed a method to detect roadside traffic panels and extract the information on them. In the first stage, blue, white and green color segmentation and structure classification is done for the purpose of detecting traffic panels. Detected region is then extracted from source image. Based on traffic panels background color mask is used to remove non text candidates. Maximally stable extremal regions (MSER) identify the stable characters regions. Finally, MSERs from every level are combined to form the ultimate segmentation. The proposed method is evaluated on Thai traffic panels and experiments show that it performs well for both English and Thai character.
Photonic Crystal Fibers for Light Generation

We study dispersion properties of photonic crystal fibers for their use in coherent light generation in visible wavelengths through optical parametric amplification. We use a simple 2D cross-sectional model of the holey fiber and solve for the guided modes. The models developed in this study of PCFs allow us to tailor the dispersion profile of PCFs using the geometric parameters of the fiber. We obtain phase-matching in the visible and infrared wavelengths. In addition, we extracted the dispersion profile of higher order modes which could be useful in further intermodal four-wave mixing studies.
Twitch potentiation after voluntary contraction and neuromuscular electrical stimulation at various frequencies in human quadriceps femoris

Introduction: In this study we aimed to compare the extent of twitch potentiation (TP) after voluntary contraction and percutaneous electrical stimulation of muscles (neuromuscular electrical stimulation: NMES) with various stimulation frequencies at equivalent target levels. Methods: Isometric knee extensions of 10 s were performed at a 40% maximal voluntary contraction level by voluntary or NMES conditioning contractions at 20, 40, and 80 HZ of the quadriceps femoris muscle. Twitch responses were elicited by stimulating the femoral nerve transcutaneously at supramaximal intensity. Results: NMES at 80 HZ induced significantly less TP (128.7 ± 17.1%) than voluntary contraction (156.2 ± 23.1%), whereas no statistical difference was found in TP among voluntary and 20‐ and 40‐HZ NMES conditioning contractions (170.8 ± 21.1% and 162.7 ± 16.9% for 20‐ and 40‐HZ NMES, respectively). Conclusion: Stimulation frequency of NMES determines whether NMES can induce TP comparable to that after voluntary contraction. Muscle Nerve 45: 110–115, 2012
Echiniscus siticulosus (Echiniscidae: spinulosus group), a new tardigrade from Western Australian scrub

ABSTRACT Australian fauna is widely recognised for its high levels of endemism, and tardigrade fauna does not seem to be an exception in this respect. The richness of xerothermic habitats in Australia, often occupied by heterotardigrade family Echiniscidae, entails high abundance and uniqueness of echiniscid assemblages. A new gonochoristic/dioecious echiniscid species was found in large numbers in samples from Western Australia. Echiniscus siticulosus sp. nov., characterised by dominant large cuticular pores in the dorsal sculpture and appendages in the form of spines, represents the spinulosus group but can be distinguished from the known members of this species complex by a unique combination of traits: peculiar faceting of the caudal plate formed by ridge-shaped epicuticular extensions and pore morphology. An amended phenotypic diagnosis of Echiniscus spiniger Richters 1904, the species morphologically most similar to the new species, is also presented.
Contemporary advanced statistical methods for the science of educational research: Principal components analysis versus L’ analysee factorielle des correspondances

The current paper analyses two different statistical techniques: i.e., principal components analysis (PCA) and correspondence analysis (L’analysee factorielle des correspondances) (AFC). A survey was carried out using a structured questionnaire for a sample of 135 nurses which studied in the School of Pedagogical and Technological Education (ASPETE) in Greece. Tangibility, Reliability, Responsiveness, Assurance, Empathy and Associability subscales are related to Qualitative Services ASPETE offers. These subscales were measured by 24 items, rated on a seven-point Likert scale. The study focuses on the presentation of the two main types of clustering methods, PCA and AFC. Lee and Lin’s model contains a one-item scale developed to measure overall service quality and a one-item scale for customer satisfaction. The assessment of the students’ satisfaction degree is evaluated based on a seven-step on the Likert scale statement, investigating the extent that the respondents are satisfied from the experience they had with the specific tertiary education organisation (CSF).

Striatal Alterations of Secretogranin-1, Somatostatin, Prodynorphin, and Cholecystokinin Peptides in an Experimental Mouse Model of Parkinson Disease*S

The principal causative pathology of Parkinson disease is the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta projecting to the striatum in the brain. The information regarding the expression of neuropeptides in parkinsonism is very limited. Here we have elucidated striatal neuropeptide mechanisms in experimental parkinsonism using the unilateral 6-hydroxydopamine model to degenerate dopamine neurons. A thoroughly controlled sample preparation technique together with a peptidomics approach and targeted neuropeptide sequence collections enabled sensitive detection, identification, and relative quantitation of a great number of endogenous neuropeptides. Previously not recognized alterations in neuropeptide levels were identified in the unilateral lesioned mice with or without subchronic 3,4-dihydroxy-l-phenylalanine administration, the conventional treatment of Parkinson disease. Several of these peptides originated from the same precursor such as secretogranin-1, somatostatin, prodynorphin, and cholecystokinin. Disease-related biotransformation of precursors into individual peptides was observed in the experimental model of Parkinson disease. Several previously unreported potentially biologically active peptides were also identified from the striatal samples. This study provides further evidence that neuropeptides take part in mediating the central nervous system failure associated with Parkinson disease.

Effect of fiber source on cell wall digestibility and rate of passage in rabbits.

The influence of fiber source on fiber digestion and mean retention time was investigated. Six fibrous feedstuffs with wide differences in chemical composition and particle size were selected: paprika meal, olive leaves, alfalfa hay, soybean hulls, sodium hydroxide-treated barley straw, and sunflower hulls. Six diets were formulated to contain one of these ingredients as the sole source of fiber. To avoid nutrient imbalances, fiber sources were supplemented with different proportions of a concentrate free of fiber based on soy protein isolate, wheat flour, lard, and a vitamin and mineral mix to obtain diets containing at least 18.5% CP and 5% starch. Fecal apparent digestibility of nonstarch polysaccharides (NSPd) and its monomers, NDF, NDF-ADL, and ADF-ADL, were determined using four New Zealand White x California growing rabbits per diet. Total, ileorectal, and cecal mean retention times (tMRT, i-rMRT, and cMRT, respectively) were determined for diets based on paprika meal, olive leaves, soybean hulls, and sunflower hulls in 16 does (four per diet) fitted with T-cannulas at the terminal ileum. In both trials, DMI was negatively correlated with the proportion of fine particles (FP: < .315 mm) and positively correlated with the proportion of large particles (LP: > 1.25 mm) (P < .01). Stepwise regression analysis showed that FP was the dietary characteristic best related to digestibilities of NSP, uronic acids, glucose and NDF, tMRT, and cMRT (P < .001), showing a positive correlation with these variables. In all these cases, this procedure selected the proportion of large particles as a second variable in the model. Degree of lignification of NDF, considering lignin as the difference between ADL and acid detergent cutin, was only included as the third variable for the model of NDF digestibility. Digestibility of NSP was positively correlated with those of NDF, NDF-ADL, and ADF-ADL (r = .82, .87 and .85, respectively, P < .001); the latter was also highly correlated with the digestibility of the glucose included in the NSP fraction (r = .86; P < .001). Cecal mean retention time accounted for 63% of average tMRT, for most of the variability in tMRT (r = .99; P < .001), and was positively related to NSPd (r = .89; P < .001). From these results, we conclude that particle size is a major factor affecting fiber digestion efficiency, rate of passage, and feed intake in rabbits.
Développement et caractérisation d'un nouveau modèle expérimental de la maladie d'Alzheimer chez le rat non transgénique

La maladie d'Alzheimer (MA) est caracterisee par un declin progressif des fonctions cognitives avec une deterioration de la memoire, une atrophie cerebrale et deux lesions histologiques caracteristiques retrouvees lors d'examens post-mortem : les plaques extracellulaires de peptide β-amyloide et les enchevetrements intracellulaires de la proteine Tau anormalement phosphorylee. De nombreux modeles animaux de la MA ont ete developpes afin de comprendre et de tester differents traitements diriges contre cette pathologie. Cependant, aucun modele de rongeur non transgenique, developpant a la fois les plaques amyloides et la pathologie neurofibrillaire, n'est disponible a ce jour. L'objectif de cette etude est de developper le premier modele non transgenique, developpant les deux lesions histologiques caracteristiques de la MA chez le rat. Le principe consiste a realiser une injection concomitante et intrahippocampale d'un AAV (virus associe aux adenovirus) recombinant contenant le gene humain de la proteine Tau presentant la mutation P301L, et du peptide Aβ1-42 qui est le principal composant des plaques amyloides. Apres plusieurs experiences, nous avons obtenu un modele animal representatif des stades precoces de la MA, c'est-a-dire avec des lesions focalisees dans l'une des premieres structures du cerveau affectee par la MA : l'hippocampe. La presence des deux lesions histopathologiques caracteristiques de la maladie, accompagnee d'une astrocytose, a ete observee par immunohistofluorescence. Une deterioration de la memoire concernant plus particulierement la memoire de travail, ainsi que des anormalites de l'activite electrique cerebrale et notamment durant les phases de sommeil paradoxal, enregistrees par electroencephalographie, ont egalement ete mises en evidence.
Dietary Indicators for Assessing the Adequacy of Population Zinc Intakes

The assessment of dietary zinc intakes is an important component of evaluating the risk of zinc deficiency in populations, and for designing appropriate food-based interventions, including fortification, to improve zinc intakes. The prevalence of inadequate zinc intakes can describe the relative magnitude of the risk of zinc deficiency in the population and identify subpopulations at elevated risk. As a cornerstone to evaluating the adequacy of population zinc intakes globally, a set of internationally appropriate dietary reference intakes must be defined. The World Health Organization/Food and Agriculture Organization/International Atomic Energy Agency (WHO/FAO/IAEA) and the Food and Nutrition Board/US Institute of Medicine (FNB/IOM) have presented estimated average requirements (EAR) for dietary zinc intake, and, more recently, the International Zinc Nutrition Consultative Group (IZiNCG) presented a revised set of recommendations for international use. A prevalence of inadequate zinc intakes greater than 25% is considered to represent an elevated risk of population zinc deficiency. As the requirement estimates are derived from smaller, clinical studies and, for children, most components of the estimates are extrapolated from data for adults, it was desirable to evaluate their internal validity. The estimated physiological requirements for adult men and women appear to adequately predict zinc status as determined by biochemical indicators of status and/or zinc balance. With the use of data from available studies, the reported prevalence of low serum zinc concentration and the estimated prevalence of inadequate zinc intakes predict similar levels of risk of zinc deficiency, particularly among pregnant and nonpregnant women. Conformity between these two indicators is less consistent for children, suggesting that further data and/or direct studies of zinc requirements among children are needed.
Synergistic Anti-Tumor Effect of Cisplatin When Combined with an Anti-Src Kinase Integrin-Based Peptide

Background: It is known that active Src kinase promotes survival of ovarian cancer cell lines and inhibition of c-Src has been shown to restore sensitivity of drug-resistant human ovarian cancer cells to cisplatin. In this study we examined the effects of a 10 mer peptide on proliferation of human colon and ovarian cancer cells when used alone and in combination with cisplatin. Materials and Methods: A 10 mer peptide, RSKAKNPLYR, derived from a 15 mer ERK2 binding sequence present on the cytoplasmic domain of the β6 integrin subunit was tested for its effect on proliferation of HT29 colon cancer cells under serum-free conditions by means of the MTT assay. Cell proliferation studies to examine the effects of cisplatin combined with peptide were conducted in serum-containing medium using the 10 mer peptide fused to a hydrophobic signal peptide sequence. Drug combination studies were performed on HT29 cells and a cisplatin-resistant cell line (ADDP) derived from an ovarian cancer cell line A2780. The effects of peptides on Src kinase activity were assessed in a cell-free in vitro kinase assay. Results: The 10 mer peptide was as effective as the 15 mer parent compound at inhibiting proliferation of HT29 cells. Exposure of HT29 and ADDP cells to a combination of cisplatin and the fusion peptide resulted in synergistic inhibition of cell growth. Both the 10 mer peptide alone and when fused to the signal peptide sequence inhibited Src kinase activity. Conclusion: Our findings raise the possibility of combination therapy comprising peptide and cisplatin for cisplatin-resistant ovarian cancers and other cancers that are high expressors of c-Src.
Liquid-ChromatographicDeterminationof HyaluronicAcid in Pleuraland AsciticFluids

A previously described method for determination of hyaluronic acid is modified for the analysis of pleural and ascitic fluids. After 20 tL of the acellular supernate is precipitated with ethanol, the precipitate is digested overnight with chondroitinases and chondroitin sulfatases. The content of hyaluronic acid-derived disaccharide is then analyzed by “high-performance” liquid chromatography. The high sensitivity (detection limit, <0.1 g of hyaluronate-derived uronic acid per milliliter) and reproducibility (SD = 4% of the mean) enable accurate determination of hyaluronic acid, even in effusions from patients without signs of mesothelioma. The range of values obtained for pleural and ascitic fluids from patients without signs of this kind of tumor is the same as that found by using other techniques, being slightly higher in those patients showing signs of tissue destruction. The concentrations of hyaluronic acid were considerably increased in most, but not all, of the cases of mesothelioma.
