Thermal impairment of reproduction is differentially expressed in maiden and repeat spawning Atlantic salmon

Groups of maiden or repeat spawning Atlantic salmon were maintained during vitellogenesis in austral autumn at either 14 C or 22 C through until April when all fish were transferred to a spawning temperature of 8 C. There was no difference in body weight within groups for maidens and repeats, with repeats being consistently larger than maidens, no difference in condition factor among groups, but consistently higher gonad weight in repeats than maidens. Gonadosomatic index (GSI) and follicle diameter were suppressed in both maidens and repeats at 22 C, with the effect being most marked in repeat spawners. Relative fecundity (egg kg) determined from ovarian tissue samples also showed depression in repeats at 22 C. Fish from both age classes held at 22 C had a higher proportion of atretic follicles. Plasma levels of estradiol-17β (E2) were strongly depressed in both maidens and repeats exposed to 22 C throughout autumn but there was some evidence of recovery among maiden fish by late April. A similar effect was seen on plasma testosterone (T) levels. Plasma cortisol levels were generally low and typical of levels in unstressed fish indicating that stress did not account for the inhibitory effects observed Hepatic zona pellucida protein gene expression was significantly inhibited in both maiden and repeat spawning fish reared at 22 °C, but with some evidence of recovery after temperature reduction to 8 °C. Hepatic vitellogenin (Vtg) gene expression was also lower in both maiden and repeat spawning fish exposed to 22 °C and this was accompanied by reduced plasma Vtg levels in maidens, but not repeats at 22 C. Maidens at 14 C began ovulating first followed by repeats at 14 C, then repeats at 22 C followed by maidens at 22 C. There was reduced fertility in maidens at 22 C relative to both maidens and repeats at 14 C, whereas repeats at 22 C showed intermediate fertility between 14 C fish and 22 C maidens. Survival to the eyed egg stage was highest in maidens at 14 C, significantly suppressed at 22 C in maidens, and at intermediate levels in repeats at both temperatures. This suggests that repeat spawning Atlantic salmon may be more robust in the face of thermal insult which combined with their larger size and egg production, could make their use desirable under production situations where there was any threat of exposure to higher than normal temperature.
Power spectrum to probe turbulence in Interstellar medium using 21cm line

Turbulent dynamics generate random fluctuations in density and velocity in the Interstellar Medium (ISM) of spiral and dwarf galaxies. Observationally, H~{\sc i} 21-cm radiation provides a good probe of these stochastic processes and helps us to know more about their nature and generating mechanism. Structure function, auto-correlation function, power spectrum are some of statistical estimators of these fluctuations which have been used in literature, whose studies helps in understanding the generating mechanisms of these structures. In this thesis we are interested in estimating the column density and velocity power spectrum at scales as large as 10 Kpc, to understand the energy associated with these structures and the type of forcing of the turbulence. Estimating power spectrum from observations can be done either by using the directly measured quantity visibility or by reconstructing the sky brightness distribution (or image) from the visibilities. By using simulated observations of a model galaxy with known power spectrum we find that the visibility based estimator reproduce the true power spectrum. The image based estimator has a scale dependent bias that is highly correlated to the incompleteness in the baseline coverage of the interferometer. Interestingly, we found that the noise in the reconstructed image has zero mean and hence the locally averaged quantities estimated from the reconstructed image are unbiased. We implement the visibility moment estimator as discussed in Dutta et al. (2015) and estimate the line of sight velocity fluctuation of the spiral galaxy NGC6946. Our result strongly indicate presence of large scale turbulence in the spiral galaxies. We conclude that we would need to have higher signal to noise H~{\sc i}observations to definitively comment on the generating mechanisms of the large scale turbulence.
Cytogenetic analysis of the Y chromosome of native brazilian bovine breeds: preliminary data

espanolEl objetivo de este trabajo fue realizar un estudio preliminar del cariotipo de bovinos de razas brasilenas: Curraleiro, Crioulo Lageano y Junqueira disponibles en la granja Parque perteneciente a Embrapa Recursos Geneticos y Biotecnologia, Brasilia, DF y de los Pantaneiros ubicados en el norte del Pantanal, pertenecientes a la finca Promissao, Pocone, MT. Fueron analizados los cariotipos de 29 machos a traves de su tipo morfologico de cromosoma Y, submetacentrico o acrocentrico, tipos estos considerados como marcadores para las subespecies taurinas y cebuinas, respectivamente. El resultado mostro que, dentro de los seis sementales Curraleiros evaluados, cuatro presentaron Y de cebu (acrocentrico) y dos de taurino (submetacentrico), sugiriendo contaminacion racial por Cebu. Sin embargo, todos los Pantaneiros analizados presentaron exclusivamente cromosoma Y de Cebu (acrocen-trico), mientras que los bovinos Crioulo Lageano y Junqueira presentaron solo Y submetacentrico, confirmando su origen taurino. EnglishThe present work is a preliminary cytogenetic study carried out on 29 males of the Brazilian breeds Curraleiro, Crioulo Lageano, Junqueira and Pantaneiro, available at Embrapa Genetic Resources & Biotechnology, Brasilia, DF and Promissao farm, Pocone, MT. The objective was to investigate their Y chromosome morphology, whether submetacentric or acrocentric, consi-dered as markers of the taurine and zebuine subspecies, respectively. The results showed that of the six Curraleiro animals analyzed, four had an acrocentric and two had a submetacentric Y chromosome, indicating contamination by zebu breeds. All Pantaneiro bulls analyzed had exclusively zebuine (acrocentric) Y chromosome. On the other hand, the Crioulo Lageano and Junqueira bulls had submetacentric Y chromo-somes, indicating their taurine origin.
Detection of tubes in radiographs using canny edge detection and progressive Hough transforms

An automated method for detecting tubes and catheters in chest radiographs could improve patient safety and healthcare efficiency by helping radiologists to more quickly and accurately identify mal-positioned tubes. We propose a method for automatically detecting tubes that first uses a Canny edge detector for the initial identification of edges, followed by a windowed variant of the Hough transform, a common line detection algorithm, which is used to identify potential tube pixels. Our method employs repeated applications of a parallel-line-specific Hough transform to the same image with progressively lower thresholds for minimum line length. Information about the parallel lines identified in the initial Hough transforms is retained and used to help later, lower threshold runs to more selectively identify potential tube sections.
ANN‐based grid voltage and frequency forecaster

This paper presents a method for the forecasting of the voltage and the frequency at the point of connection between a battery energy storage system installed at The University of Manchester and the local low-voltage distribution grid. The techniques are to be used in a real-time controller for optimal management of the storage system. The forecasters developed in this study use an artificial neural network (ANN)-based technique and can predict the grid quantities with two different time windows: one second and one minute ahead. The developed ANNs have been implemented in a dSPACE-based real-time controller and all forecasters show very good performance, with correlations coefficients >0.85, and mean absolute percentage errors of <0.2%.
Effect of Chilean propolis on cariogenic bacteria Lactobacillus fermentum

La caries dental es una de las enfermedades infecciosas mas prevalentes en el mundo. Entre las bacterias involucradas en esta patologia se encuentran Streptococcus mutans, Streptococcus sobrinus, Actinomyces spp. y Lactobacillus spp. La industria farmaceutica ha volcado sus esfuerzos al descubrimiento de nuevos productos antibacterianos ante el aumento de resistencia a los ya conocidos. El propoleos se ha utilizado como tal, desde tiempos antiguos, por lo que se ha investigado su efecto contra variados microorganismos. En este estudio se evaluo el efecto antimicrobiano de seis extractos etanolicos comerciales de propoleos, sobre la bacteria Lactobacillus fermentum. Esta fue aislada luego de su identificacion mediante PCR con el uso de primers especie especificos, posterior al cultivo microbiologico de muestras de caries de pacientes con indicacion de extraccion de pieza dental, y se detecto en 9 de 40 pacientes, correspondiendo a un 22%. El estudio de susceptibilidad se realizo mediante dilucion en microplacas y se comprobo la actividad antimicrobiana en cuatro de los seis extractos etanolicos de propoleos utilizados, difiriendo en la concentracion efectiva contra el microorganismo, lo que puede ser atribuido a factores como el origen botanico, el lugar geografico y la estacion de recoleccion. Los propoleos mostraron concentraciones de polifenoles que variaron entre 9 ± 0,3 y 85 ± 2,1 mg/mL. El analisis cromatografico permitio detectar la presencia de acido cafeico, miricetina, quercetina, kaempferol, apigenina, pinocembrina, galangina y acido cafeico fenil ester (CAPE). Nuestro estudio demuestra la accion antimicrobiana del propoleos sobre L. fermentum, patogeno relacionado al desarrollo de caries.
Waste water treatment of resorcinol production

Amount of acid reddish brown wastewater are produced in the process of resorcinol formed by m-phenylenediamine hydrolysis. The waste water contains high-concentration mphenylenediamine, m-aminophenol, resorcinol and other impurities which can’t be directly treated by biochemistry method. At first, formaldehyde is added to waste water and condensed with m-phenylenediamine, m-aminophenol and resorcinol. The reaction product is oligomeric solid polymer separated by filtration from the waste water. The solid polymer by-product can be used as plasticizers of rubber. The ratio of formaldehyde and amine substance is investigated for the aim to minimal amine residues and best color of ammonium sulfate product. The optimal mole ratio of formaldehyde and amine substance is 4:1. Secondly,ammonia water is added to neutralize the acidity of the waste water. It is found that other impurities reacted with ammonia and precipitation from the solution in the neutralization process. At pH 7~8 of the neutralized water, the color and the nitrogen content of the final ammonium sulfate product are optimal. Thirdly, the low boiling point organic compounds (methanol, n-butyl acetate etc.) are removed by stripping. Then activated carbon is added in waste water for decoloration. Finally, water was evaporated for obtaining ammonium sulfate product. An orthogonal experiment with three factors and four levels is designed about bleaching temperature, activated carbon quantity and bleaching time. The experiment indexes are the nitrogen content and color of the ammonia sulfate product. Using extremum difference analysis, the optimal conditions are the bleaching temperature 90°C, the mass fraction of activated carbon 3‰, and the bleaching time 30 minutes. The evaporated water vapor is condensed and reused as process water, which can minimize the waste water discharge of the production process. Powered by TCPDF (www.tcpdf.org) PRES17 conference
Genealogy of the Genome Components in the Highly Homogeneous Pandemic Vibrio parahaemolyticus Population

Bacterial genomes evolve through two different mechanisms: 1) changes in or occasional loss of ancestral genes, which preserve the founder clonal genealogy or frame, and 2) sporadic gains of new genes via horizontal gene transfer, which introduces DNA with a different genealogy or clonal frame. Evolution has led to the emergence of a pathogenic strain pandemic of Vibrio parahaemolyticus, which has propagated globally, causing large outbreaks of seafood-associated diarrhea. The low sequence diversity of the pathogenic strain of Vibrio parahaemolyticus genome provides a model that can reveal evolutionary mechanisms that are hidden in bacteria with a greater diversity. Here, we assess the clonal genealogy of the genome components of Vibrio parahaemolyticus and identify recombinant segments in 31 isolates obtained worldwide. By comparing whole genomes using a procedure that accounts for at least 98% of the reads obtained from any isolate after high throughput sequencing, we determined that the fraction of the whole genome retaining the founder clonal frame varied from 96.7%-100% of the accountable reads. The fraction in chromosomes with other genealogies varied from 0%-3.3% and in extra-chromosomal elements from 0%-4.2%, with the relative impact of mutation and recombination varying greatly between isolates. The likely causes for this variation are proposed.
Interest Rate Setting by the ECB: Words and Deeds

This Paper discusses interest rate setting by the ECB between 1999 and 2004. I develop from the Monthly Bulletins quantitative indicators of the Governing Council’s assessment of inflation, economic activity, and M3 growth, and investigate their impact on its interest rate decisions. I also estimate reaction functions with ordered probit techniques, using the Monthly Bulletins to guide the choice of variables for the analysis. The results show that the ECB reacts strongly to economic sentiment indicators as measures of the state of the real economy. Furthermore, I find statistically significant reactions to inflation and M3 growth.
Classic models of population dynamics: assumptions about self- regulative mechanisms and numbers of interactions between individuals

Stochastic model of migrations of individuals within the limits of finite domain on a plane is considered. It is assumed that population size scale is homogeneous, and there doesn’t exist an interval of optimal values of population size (Alley effect doesn’t realize for population). For every fixed value of population size number of interactions between individuals is calculated (as average in space and time). Correspondence between several classic models and numbers of interactions between individuals is analyzed.
Oral health profile of schoolers attended at the Pediatric Dentistry Clinics of the Federal University of Uberlândia

Introduction and Objective: To characterize the socioeconomic profile, the need for dental treatment of children from zero to 12 years of age attended at Pediatric Dentistry Clinics. Material and methods: We evaluated 552 dental records and verified the child’s birth date, frequency of procedures performed according to tooth type and number of appointments. Results: The results showed that 265 (48.01%) children were females and 287 (51.99%) males, witha mean age of 4 years (±7.5). Of the total, 168 (30.43%) were from families with family income of 1 to 2 minimum wages. A total of 279 (50.54%) children were attended in 2009, 123 (22.29%) in 2010, 150 (27.17%) in 2009/2010. There were 3,350 visits, where 1,833 teeth (1,447 deciduous and 386 permanent) were treated. Of the total number of procedures performed (946), 620 were preventive and 1,326 curative procedures. There was a difference between the preventive and curative procedures performed. Conclusion: Itwas concluded that most of the children attended were infants and preschool children, belonging to families with low socioeconomic status and the deciduous dentition received the greater number of curative procedures.
International Conference on High Performance Cutting , HPC 2014 FPGA based monitoring platform for condition monitoring in cylindrical grinding

Sensor systems for machine condition monitoring face many challenges in the world of digitized data with an emphasis being placed on the application of high performance feature extraction computing systems. These systems must be robust, reliable and economically viable before being adopted by industry. This paper describes a platform for condition monitoring that has been developed using a field programmable gate array (FPGA) for the real time signal processing in a complex grinding process. An architecture which can sample 16 channels at 12.5kHz and perform 1024 bin FFTs on a National Instruments CompactRIO with a Xilinx Virtex 5 LX50 is described. FPGA resource utilization figures for multiple configurations of this FFT are reported. The FPGA also performs an exponentially time weighted RMS on 10 acceleration channels and samples four quadrature encoded axis channels in real time. Results are displayed as conditioned data to a machine operator HMI for machine and process evaluation. The research demonstrates how multisensory multiprocessing platform approach can be realized and implemented in industry for future high end condition and process monitoring applications. © 2014 The Authors.

Robust Estimates of Exporter Productivity Premia in German Business Services Enterprises

A large and growing number of micro-econometric studies show that exporting firms are more productive than firms that sell their products on the home market only. This so-called exporter productivity premium qualifies as a stylized fact. Only recently researchers started to look at the role of extreme observations, or outliers, in shaping these findings. These studies use micro-econometric methods that are robust against outliers to show that very small shares of firms with extreme values drive the result. The large exporter productivity premium found for samples of firms including outliers are dramatically smaller in samples without these extreme observations. Evidence on this, however, is limited so far to firms from manufacturing industries. This note adds comparable evidence for firms from the business services industries. We find that the estimated exporter productivity premium is statistically significant and relevant from an economic point of view when a standard fixed effects estimator is used to control for unobserved firm characteristics, but that it drops to zero when a robust estimator is applied.
Planktonic foraminifera-derived environmental DNA extracted from abyssal sediments preserves patterns of plankton macroecology

Abstract. Deep-sea sediments constitute a unique archive of ocean change, fueled by a permanent rain of mineral and organic remains from the surface ocean. Until now, paleo-ecological analyses of this archive have been mostly based on information from taxa leaving fossils. In theory, environmental DNA (eDNA) in the sediment has the potential to provide information on non-fossilized taxa, allowing more comprehensive interpretations of the fossil record. Yet, the process controlling the transport and deposition of eDNA onto the sediment and the extent to which it preserves the features of past oceanic biota remains unknown. Planktonic foraminifera are the ideal taxa to allow an assessment of the eDNA signal modification during deposition because their fossils are well preserved in the sediment and their morphological taxonomy is documented by DNA barcodes. Specifically, we re-analyze foraminiferal-specific metabarcodes from 31 deep-sea sediment samples, which were shown to contain a small fraction of sequences from planktonic foraminifera. We confirm that the largest portion of the metabarcode originates from benthic bottom-dwelling foraminifera, representing the in situ community, but a small portion (
The performance of three ordination methods

The performance of robust principal component analysis (RPCA), detrended correspondence analysis (DCA) and non-metric multidimensional scaling (NMDS) with two demersal fish data sets were assessed in terms of their stability to bootstrap-generated sample variation and the method's ability to reflect a well-known depth gradient. Stability was assessed for both species and site orderings and configurations, using scaled rank variance (SRV) and Spearman (q) and Procrustes correlations (t0). The NMDS site and species orderings showed the highest stability. DCA performed best in terms of site ordination stability, but NMDS performed best in terms of species ordination stability. In terms of matching the expected ecological variation, NMDS was the most sensitive method for the wider-depth gradient data and DCA was the most sensitive for the narrower-depth gradient data. According to the sensitivity and informative power criteria associated with the stability assessment, t0 was the best methodological approach for site ordinations, and SRV for species ordinations.
Sediment transfer mapping in a high-alpine catchment using airborne LiDAR

In the high-alpine zones of the Mattertal/VS, gravitational processes are widespread. Changes in the permafrost zones are reducing the cohesion of high-alpine slopes and produce additional material, which can be transported to the channels below. Such sediment-filled gullies can act as debris-flow sources. Frequent topographical surveys are very difficult to accomplish due to the poor accessibility of the steep terrain endangered by frequent rock fall and debris slide events. We use airborne laser scanning (LiDAR) from two different dates (summer 2010 and summer 2011) to map sediment transfer over the entire Grabengufer area and the lower part of the catchment, known for high levels of geomorphic activity. The fine spatial resolution of the resulting DTM’s (0.5 m) and the high positional precision (approx. 0.15 m in x,y and z) allow for a detailed analysis of the topographic changes within the one year time period. We identified areas of erosion and deposition and we quantified as well the relocated volumes. We find substantial relocation of material especially in the rock glacier area (6760 m3 erosion) as well as in the gully (23 720 m3 deposition). This information is fundamental for further debris-flow and permafrost studies in the Mattertal area. The method tested in this investigation has a big potential to be helpful for subsequent studies in other debris-flow affected regions.
