SINFONI Integral Field Spectroscopy of z ~ 2 UV-selected Galaxies: Rotation Curves and Dynamical Evolution

We present ~0. ″5 resolution near-infrared integral field spectroscopy of the Hα line emission of 14 z ~ 2 UV-selected BM/BX galaxies, obtained with SINFONI at the ESO Very Large Telescope. The average Hα half-light radius is r1/2 ≈ 4 h kpc, and line emission is detected over ≳20 h kpc in several sources. In nine galaxies, we detect spatially resolved velocity gradients, from 40 to 410 km s-1 over ~10 h kpc. The kinematics of the larger systems are generally consistent with orbital motions. Four galaxies are well described by rotating clumpy disks, and we extracted rotation curves out to radii ≳10 h kpc. One or two galaxies exhibit signatures more consistent with mergers. Analyzing all 14 galaxies in the framework of rotating disks, we infer mean inclination- and beam-corrected maximum circular velocities of vc ~ 180 ± 90 km s-1 and dynamical masses from ~0.5 to 25 × 1010 h M☉ within r1/2. The specific angular momenta of our BM/BX galaxies are similar to those of local late-type galaxies. Moreover, the specific angular momenta of their baryons are comparable to those of their dark matter halos. Extrapolating from the average vc at 10 h kpc, the virial mass of the typical halo of a galaxy in our sample is 1011.7±0.5 h M☉. Kinematic modeling of the three best cases implies a ratio of vc to local velocity dispersion vc/σ ~ 2-4 and, accordingly, a large geometric thickness. We argue that this suggests a mass accretion (alternatively, gas exhaustion) timescale of ~500 Myr. We also argue that if our BM/BX galaxies were initially gas-rich, their clumpy disks would subsequently lose their angular momentum and form compact bulges on a timescale of ~1 Gyr.
New Parties and Policy Outcomes: Theory and Evidence from Colombian Local Governments

In many democracies, increasing political competition has changed the traditional party system and brought new parties into the political arena. This study examines whether the presence of politicians from new parties aects the size of government (measured by public spending and tax revenue). The study focuses on Colombian municipalities, where new parties have been numerous and successful in recent years. Regression discontinuity estimates show that public spending and tax revenue are signicantly higher in municipalities governed by a mayor from a new party. Using information about local politics and the features of the new parties, I argue that this result can be explained by the fact that mayors from new parties are less known to voters than politicians from traditional parties.

Improvement of the EMD-SG Denoising Method

The Empirical Mode Decomposition (EMD) is a new method for processing nonlinear and non-stationary signals. In this paper, an improvement of a denoising scheme using EMD was proposed. A noisy signal was decomposed adaptively into IMFs by using EMD method. The basic principle of the original method was to filter by Savitzky-Golay filter (SG) each IMF and then to reconstruct the signal from the filtered IMFs. The new method for reducing noise was based on multiple pass the noisy IMFs through a Savitzky-Golay filter two or more times. The EMD-SG multiple pass denoising technique was tested on four noisy simulated signals (Doppler, Blocks, Bumps and Heavysine) corrupted by white Gaussian noise with different Signal-to-Noise Ratio (SNR). The performance of proposed denoising method was quantitatively evaluated using SNR and Mean Square Error (MSE). The evaluation results showed that the proposed EMD-SG multiple pass performed better than the original EMD-SG method. 
Evaluation of Bioelectrical Impedance Spectroscopy for the Assessment of Extracellular Body Water

This study evaluates bioelectrical impedance spectroscopy (BIS) measurements to detect body fluid status. The multifrequency impedance measurements were performed in five female pigs. Animals were connected to an extracorporeal membrane oxygenation device during a lung disease experiment and fluid balance was recorded. Every 15 min the amount of fluid infusion and the weight of the urine drainage bag was recorded. From the fluid intake and output, the fluid balance was calculated. These data were compared with values calculated from a mathematical model, based on the extracellular tissue resistance and the Hanai Mixture theory. The extracellular tissue resistance was also measured with BIS. These experimental results strongly support the feasibility and clinical value of BIS for in vivo assessment of the hydration status.
Modeling and Investigation of Vector Controlled Induction

The cage induction motor is the most popular machine for industrial applications. It is also the most complex from the viewpoint of drive control. Computer simulation is widely applied in various system studies. For developments of the power electronic and control system simulation provides numerous advantages such as concept proof of the circuit topology, development of the control algorithm, study of efficiency and performance. These computer based simulation techniques save costs before developing the unit. Vector (or “field-oriented”) control algorithms are widely used in high-performance drives, providing precise and responsive speed control, and guaranteeing optimized efficiency during transient operations [1, 2]. In industrial applications, vector drives are often required to operate from zero speed (including zero speed start-up). Therefore we propose a model of the AC motor drive based on the low-speed region where rotor flux components can be synthesized more easily with the help of speed and current signals.
Deregulating the Downstream Sector of the Nigerian Petroleum Industry

Nigeria is endowed with abundant natural resources, particularly crude oil and gas. A major feature of the downstream petroleum sector in Nigeria is the dominance of the government in pricing, supply and investment. Nigeria currently relies heavily on the importation of refined petroleum products despite being a major crude oil exporter. Sequel to the fall in domestic output of refined petroleum products, successive Nigerian governments have spent so much yearly in subsidizing the importation of the products for onward sale at lower rates to the Nigerian populace. Considering the huge amounts spent overtime in subsidizing the consumption of petroleum products in Nigeria, the government decided to fully deregulate the retail price of petroleum having removed the subsidies on diesel and kerosene earlier. This paper provides insights into the key issues related to petroleum subsidy reforms in Nigeria. It presents the arguments for the removal of petroleum subsidy and the weaknesses of the current subsidy regime; the likely impacts of the reform measure and arguments canvassed against its withdrawal; possible options for the reform of the petroleum sector; and suggestions for successful implementation of the oil sector deregulation policy.
Antioxidant Enzymes and Photosynthetic Responses to Drought Stress of Three Canna edulis Cultivars

Edible canna is a productive starch source in some tropical and semitropical regions. In these regions, water deficit stress is one of factors that limit the crop yield. In the present study, we investigated seven physiological indexes and photosynthetic responses of three edible canna (Canna edulis Ker.) cultivars (‘PLRF’, ‘Xingyu-1’, and ‘Xingyu-2’) under 35 days drought stress. Our results indicated that drought treatment caused visible wilting symptoms in all cultivars, especially in ‘Xingyu-1’. Coupled with the increase of wilting symptoms, relative water content (RWC) and chlorophyll content decreased progressively, malondialdehyde (MDA) content gradually increased, and key antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) activities increased first and then decreased in all three cultivars. The effect of water stress was more pronounced in ‘Xingyu-1’ than in ‘PLRF’ and ‘Xingyu-2’, and in lower leaves than in upper leaves. In addition, 35 days drought stress also significantly reduced the photosynthetic capacity. Consistent with antioxidant parameters, photosynthetic changes of ‘Xingyu-2’ were less than those of the other cultivars under water deficit stress. Drought stress caused a significant increase of water use efficiency (WUE) in ‘Xingyu-2’, but little in ‘PLRF’, and obvious decrease in ‘Xingyu-1’. These results indicated that ‘Xingyu-2’ was more tolerant to drought stress than ‘PLRF’ and ‘Xingyu-1’ by maintaining lower lipid peroxidation and higher antioxidant enzyme activities.
A DEVELOPMENTAL MODEL OF PARTNER VIOLENCE: A LONGITUDINAL STUDY

Partner violence is a crime of national concern and has significant psychological and physical injury ramifications. This study tested a developmental model of partner violence. Three cohorts of children (n=754) were followed from kindergarten entry to the age of 18 years. Structural equation models revealed that poor parent-child relationship quality and childhood externalizing problems at age 6 years predicted partner violence indirectly via its influence on early adolescent conduct problems. Person-oriented group comparisons found no childhood risk differences between those who engaged in partner violence and those who did not. Implications for prevention efforts and future research directions will be discussed.
When Credit Matters – Possible Room for ECB ’ s Success in Quantitative Easing from Selected EA Members ’ Point of View

This paper construct SVAR model for individual EA m ember states that is able to capture effects of ECB’s unconventional measures on domestic economy. We separately model innovation to ECB key interest rate representing standard interest rate p olicy as exogenous variable and effects of pure quantitative easing through change in monetary base of national central banks as endogenous variable. This allows us to differentiate between t wo separate effects of ECB’s monetary policy. By incorporating banking sector we specifically examin e effects of monetary policy on credit provisioning in individual countries. This model is applied on t hree countries that are predominantly bankoriented: Austria, Germany and France. Our results suggest that while standard interest rate policy might have an effect on credit provisioning through credit multiplier, balance sheet policy predominantly affects long-term interest rates and bank spreads but the effect evaporates rather quickly. Effectiveness of monetary policy in influe ncing the real output through credit provisioning should be called into question as we do not find si gnificant link between credit and economic output.
HPTLC METHOD FOR SIMULTANEOUS QUANTITATION OF THIOCOLCHICOSIDE, PARACETAMOL AND ACECLOFENAC IN BULK DRUG AND FORMULATION

A simple, precise and accurate HPTLC method was developed for the simultaneous estimation of thiocolchicoside (THIO), paracetamol (PAR), and aceclofenac (ACF) for the bulk drugs and their combined tablet dosage form. The method involved TLC on aluminum plates precoated with silica gel using toluene:acetone:methanol:formic acid 8:2:2:1 (v/v/v/v) as mobile phase. Densitometric scanning was performed at 263 nm. The method was validated as per ICH guidelines. Rf values of 0.13±0.03, 0.42±0.04 and 0.57±0.02 were obtained for THIO, PAR and ACF respectively. Precision, accuracy and specificity were in accordance with ICH guidelines.
THE IMPACT OF FINANCIAL SECTOR REFORMS ON AGRICULTURAL AND MANUFACTURING SECTORS IN NIGERIA: AN EMPIRICAL INVESTIGATION

The growth finance nexus has elicited considerable debate in the academia and among policy makers. This is because, among others, the current reforms in the financial sector are based on the premise that relaxing financial constraints and deepening the financial sector is essential to promote economic growth and development. To contribute to this debate, this paper uses the variance decomposition and impulse response paradigms to test whether or not financial sector variables stimulate the growth of output in agricultural and manufacturing sectors of the Nigeria economy. The results suggest that relaxing the financial development constraints and deepening the financial sector is crucial to boost economic growth in the identified two sectors.
Examining the Relationship between Instructional Leadership and Organizational Health

The aim of this study was to examine the relationship between school administrators' instructional leadership behaviours, and organizational health of schools. The participants were 538 teachers working in elementary, middle and high schools located in the Umraniye district of Istanbul. The data was gathered through the "School Principals' Instructional Leadership Behaviours Questionnaire" and the "Organizational Health Inventory". In data analysis, the arithmetic mean, Pearson Product-Moment Correlation Coefficient, and Multilinear Regression Analysis were used. The results showed that the school principals performed the instructional leadership behaviours of determining and sharing the objectives of the school at the highest level. Among the organizational health dimensions of the schools, initiating structure was perceived at the highest level, while resource support and academic emphasis were perceived at lower levels compared to other dimensions. In the study, positive and significant correlations were found between the sub-dimensions of instructional leadership behaviours and those of organizational health of schools. The sub-dimensions of instructional leadership together explained 49% of the variance in organizational health. On the other hand, only determining and sharing the objectives of the school and forming a regular instructional-learning environment and positive school climate among the instructional leadership behaviours were positive and significant predictors of organizational health of schools.
Ua Huka, une île dans l'Histoire : histoire pré-et post-européenne d'une société marquisienne

Notre etude se propose de suivre la trajectoire historique de la societe ancienne de Ua Huka, dans l’archipel des Marquises, depuis les premiers peuplements humains, aux environs de 800-900 apr. J. C. , jusqu’a l’installation des occidentaux au cours du XIXe siecle. Il apparait avant tout necessaire de reconstruire la sequence chrono-culturelle locale. L’analyse stratigraphique et la datation des enregistrements mis au jour sur des sites dunaires et interieurs permettent de reconstituer une sequence cumulee couvrant pres d’un millenaire. Des marqueurs de natures diverses sont identifies et divisent la trajectoire en plusieurs segments que nous sommes a meme de caracteriser d’un point de vue culturel. Dans un second temps, l’histoire de l’ile est interpretee au travers de grands themes d’investigation. Nous abordons l’organisation et la dynamique de l’habitat en montrant comment se forment les noyaux villageois. C’est aussi l’occasion de comprendre le fonctionnement des systemes horticoles, lui-meme integre a une synthese sur les modes de subsistance. La reconnaissance des vestiges de sites communautaires et ceremoniels nous autorise une reflexion quant au phenomene de differenciation qui s’opere de maniere unique dans la sphere politico-religieuse marquisienne. Elle est aussi completee par une etude novatrice de plusieurs depots funeraires secondaires qui caracterisent la gestion rituelle des defunts au cours de la derniere periode pre-europeenne. Enfin, le recours a une methode archeodemographique fournit pour la premiere fois une estimation generale de la population ancienne, dont on suit par ailleurs l’evolution apres le contact avec les Occidentaux
Bayesian adaptively updated Hamiltonian Monte Carlo with an application to high-dimensional BEKK GARCH models

Abstract Hamiltonian Monte Carlo (HMC) is a recent statistical procedure to sample from complex distributions. Distant proposal draws are taken in a sequence of steps following the Hamiltonian dynamics of the underlying parameter space, often yielding superior mixing properties of the resulting Markov chain. However, its performance can deteriorate sharply with the degree of irregularity of the underlying likelihood due to its lack of local adaptability in the parameter space. Riemann Manifold HMC (RMHMC), a locally adaptive version of HMC, alleviates this problem, but at a substantially increased computational cost that can become prohibitive in high-dimensional scenarios. In this paper we propose the Adaptively Updated HMC (AUHMC), an alternative inferential method based on HMC that is both fast and locally adaptive, combining the advantages of both HMC and RMHMC. The benefits become more pronounced with higher dimensionality of the parameter space and with the degree of irregularity of the underlying likelihood surface. We show that AUHMC satisfies detailed balance for a valid MCMC scheme and provide a comparison with RMHMC in terms of effective sample size, highlighting substantial efficiency gains of AUHMC. Simulation examples and an application of the BEKK GARCH model show the practical usefulness of the new posterior sampler.
Dissolution enhancement of glimepiride dispersion using glyceryl monostearate and β-cyclodextrin as carrier.

Glimepiride is an antidiabetic drug of sulfonylurea group and indicated for the treatment of type 2 diabetes mellitus. The present study was conducted to enhance the dissolution rate of glimepiride solid lipid nano particle dispersions using hot homogenization method and glimepiride solid dispersion by precipitation method. Solid lipid nanoparticles have been used as suitable carriers for delivery of drug with poor solubility. In this investigation glyceryl monostearate and stearic acid were used as solid lipid, Lutrol F-68 as surfactant, Tween 80 as stabilizer and the used polymer were urea crystal and β-cyclodextrin. Three formulations were prepared in different ratios for two methods and were designated as GMLN1 to GMLN3 in case of hot homogenization method and GMP1 to GMP3 for precipitation method. The evaluation of all the dispersions were done by in vitro dissolution studies using US Pharmacopeia type II apparatus (paddle method) in 900ml distilled water at 50 rpm to a temperature of 37°C ± 0.5°C for 45 minutes. In situ and externally sink method revealed the release pattern of drug was found to follow zero order, first order and Korsmeyer-Peppas equations. Improved dissolution profile was observed in all the solid lipid nano particle dispersions as compared to pure drug as well as market preparation. Thus, glyceryl monostearate and β-cyclodextrin can be successfully used as carrier for improvement of dissolution and bioavailability of glimepiride.

Biocompounds content in organic and conventional raspberry fruits

Raspberry fruits are a source of vitamin C, phenolic acids and flavonoids, including anthocyanins. There is scientific evidence that allows to assume that organic fruit and vegetables contain more bioactive compounds with antioxidant properties than plant crops from the conventional farming. The aim of the presented studies was to compare the contents of antioxidant compounds in two varieties of raspberries fruits came from certified organic and conventional production. The vitamin C content was determined using the titration method and spectrophotometry, and the content and composition of polyphenols (flavonols, anthocyanins and phenolic acids) was determined by HPLC method, with identification of individual phenolic compounds according to the Fluca and Sigma Aldrich standards. Significant differences were found between raspberry fruits in the content of the analyzed compounds. Organic raspberries contained more flawonols, phenolic acids and anthocyanins in comparison to conventional ones. The applied method of cultivation did not impact the content of vitamin C in raspberries tested. The results show that the cultivation system is one of the factors influencing the content of certain substances with antioxidant character in raspberry fruits. However, there is a need for further detailed research, especially research carried out in similar growing conditions. Keywords: raspberries, organic fruits, flavonoids, phenolic acids, vitamin C
Determinants of Sovereign CDS Spreads: Evidence from Brazil

Credit derivatives are important financial instruments used to transfer credit risk of loans and other assets. Among them stands out the so-called sovereign credit default swap (CDS), which works as a kind of insurance against sovereign credit risk. The international literature has shown a correlation between sovereign CDS, CDS index and stock index. The present study aims to identify and analyze the determinants factors of the Brazilian sovereign credit default swap spreads (CDSs Brazil), from a multiple linear regression model adjusted for the period May 2009 to May 2014. The results show that the S&P 500 has a greater effect on the CDSs Brazil, followed by the factors Bovespa index (Brazilian stock market index), iTraxx index, European index CDS, FX volatility and CDS USA. Moreover, the CDSs Brazil has a positive relationship with the stock indexes and a negative relationship with the other variables, results similar to some studies in the literature.
Quantification of halophilic Azospirillum from mangroves

the rate of nitrogen fixation in Azospirillum brasilense were found to be maximum at pH 7.0. At 3 % NaCl, it showed better growth and production of IAA, however the rate of nitrogen fixation was slowed down at 1 % NaCl and was completely arrested at 1.5 %. The percentage of germination in coastal crop plants increased by 70 % in black gram and 45 % in rice with the inoculation of Azospirillum brasilense compared with control. The saline tolerant Azospirillum is recommended as biofertilizer for improving crop yield in coastal agricultural fields Mangroves represent a unique and ecologically important coastal habitat in the tropical and subtropical belts and are frequently seen as pioneer vegetation in coastal area 1 . A number of static and dynamic biological, physical and chemical factors are known to influence the development and stability of a mangrove community. These factors and their interactions play a significant role in the nutrient flows in the system and it becomes necessary to understand the various proc
Mitered Fractal Trees: Constructions and Properties

Tree-like structures, that is, branching structures without cycles, are attractive for artful expression. Especially interesting are fractal trees, where each subtree is a scaled and possibly otherwise transformed version of the entire tree. Such trees can be rendered in 3D by using beams with a polygonal cross section for the trunk and the branches. The challenge is to connect the beams at the branching points in such a way that the beam edges nicely meet. This is related to the miter joint, but does not necessarily involve ternary miter joints. In this article, we explore a parameterized family of fractal trees that can be rendered with polygonal beams whose edges meet properly at the branching points. We present various constructions and analyze their mathematical properties. Some of these trees have been constructed as artwork in wood and bronze.
