Extrasolar planets and brown dwarfs around A-F type stars. VI. High precision RV survey of early type dwarfs with HARPS

(Abridged) Aims: Systematic surveys to search for exoplanets have been mostly dedicated to solar-type stars sofar. We developed in 2004 a method to extend such searches to earlier A-F type dwarfs and started spectroscopic surveys to search for planets and quantify the detection limit achievable when taking into account the stars properties and their actual levels of intrinsic variations. We give here the first results of our southern survey with HARPS. Results: 1) 64% of the 170 stars with enough data points are found to be variable. 20 are found to be binaries or candidate binaries (with stars or brown dwarfs). More than 80% or the latest type stars (once binaries are removed) are intrinsically variable at a 2 m/s precision level. Stars with earlier spectral type (B-V <= 0.2) are either variable or associated to levels of uncertainties comparable to the RV rms observed on variable stars of same B-V. 2) We have detected one long-period planetary system around an F6IV-V star. 3) We have quantified the jitter due to stellar activity and we show that taking into account this jitter in addition to the stellar parameters, it is still possible to detect planets with HARPS with periods of 3 days (resp. 10 days and 100 days) on 91% (resp. 83%, 61%) of them. We show that even the earliest spectral type stars are accessible to this type of search, provided they have a low vsini and low levels of activity. 4) Taking into account the present data, we compute the actually achieved detection limits for 107 targets and discuss the limits as a function of B-V. Given the data at hand, our survey is sensitive to short-period (few days) planets and to longer ones (100 days) at a lower extent (latest type stars). We derive first constrains on the presence of planets around A-F stars for these ranges of periods.
Report on the 8 th International Symposium on the Role of Soy in Health Promotion and Chronic Disease Prevention and Treatment 1 , 2

The international soy symposium held in Tokyo, November 9–12, 2008, was the eighth in a series that began in 1994. This most recent meeting is noteworthy for several reasons. First, it was held in the country most identified with the foods that are the focus of the meeting. Soyfoods were first consumed in China more than a millennium ago, but it is the low incidence of breast and prostate cancer, heart disease, and hot flashes in Japan, despite the high socioeconomic status of this country, that helped fuel interest in the early 1990s in the possible chronic disease-preventive properties of soy and certain soybean constituents. Second, it was the first time an entire session was devoted to equol, a bacterially derived product of the soybean isoflavone daidzein, which is produced by only ;30% of Westerners and has been proposed to be an especially beneficial compound, i.e., the equol hypothesis. And third, there was greater emphasis during this meeting than at past ones on addressing some of the more hotly debated health effects linked with soy intake. The conference was attended by . 250 scientists from 20 countries; there were 33 oral and 40 poster presentations during the 4-d event. The majority of presentations at the Tokyo symposium focused on isoflavones. In this article, the major findings presented at the symposium are highlighted, and commentary about those findings and related background is provided. J. Nutr. 139:
Is the gain from a groundwater management policy insignificant

The point of departure of this work is Gisser and Sanchez’s (1980) findings according to which an optimal groundwater management policy would not generate significant gain with respect to a situation with no optimal control. Their theoretical result is evidently checked for a fixed number of agents when the storage capacity of the aquifer is relatively large. The article proposes to add an open-access component into Rubio and Casino’s (2001) adaptation from Gisser and Sanchez’s (1980) seminal model, in order to make the number of farmers exploiting the resource endogenous. The author then shows that, at the stationary equilibrium, the Gisser and Sanchez’s theoretical result does not persist anymore since the rent is zero at this state, although it is positive under optimal control of a water agency.
The Feldstein- Horioka paradox in the perspective of foreign direct investment (FDI): A pragmatic validation

The purpose of this study is to test fundamental relationship between domestic saving and domestic investment for Pakistan from 1972 to 2008. Saving and investment are closely related to highlight the economic state of affairs of a country. Saving is a strapping source to enhance investment. Raising income enables people to increase consumption and saving level. The higher the level of income will improve the level of saving and ultimately investment will go up. Johanson co-integration shows that there is long run relationship between saving and investment. For short run dynamics and causality, the study utilizes vector error correction model (VECM). The results of VECM indicate that there is short and long run causal relation between saving and investment.
Science with MATISSE

We present an overview of the scientific potential of MATISSE, the Multi Aperture mid-Infrared SpectroScopic Experiment for the Very Large Telescope Interferometer. For this purpose we outline selected case studies from various areas, such as star and planet formation, active galactic nuclei, evolved stars, extrasolar planets, and solar system minor bodies and discuss strategies for the planning and analysis of future MATISSE observations. Moreover, the importance of MATISSE observations in the context of complementary high-angular resolution observations at near-infrared and submillimeter/millimeter wavelengths is highlighted.
Comparison between indices during geomagnetic disturbances

Auroral indices AE, AU, AL, and Troshichev index from Thule, PC (Polar Cap) are compared for geomagnetic disturbances of different intensities. To identify perturbations, the indices Dst and AE have been used. Fourteen storms have been analyzed, with Dst index minimum value between –50 nT and –600 nT (86% of them are great storms). The correlation coefficient, r, between AE and PC is above 0.65 for all storms analyzed. For AL index the correlation values are close to those of AE; but r is low for AU index. Thirty-five substorms were identified, with AE maximum values between 271 nT and 2218 nT. Eighty-one percent of them have a correlation coefficient between AE and PC above 0.6 and 47% above 0.8. The values obtained do not depend on disturbance intensity. The results suggest that PC index can be used as a fast indicator of global magnetic activity in the auroral oval even during great disturbances.
The current state of e-learning at universities in Zimbabwe: opportunities and challenges

E-learning is gaining some ground in University education throughout the world. Currently, a large number of universities worldâ€“wide support e-learning in different forms. Despite this wide spread adoption of e-learning in university education, research on e-learning adoption suggests that it has not reached its full potential. This paper discusses the opportunities that exist and challenges that hinder the successful adoption of e-learning technology as a medium of instruction at selected universities in Zimbabwe. The findings and comments provided are expected to help universities develop their e-learning strategies. The participants of this study are university lecturers who are beginning to use e-learning. The results indicate that e-learning at most of the universities is still at its infant stage. This research exposes a number of reasons for the limited successes, which are related to infrastructural development, support and pedagogical considerations for e-learning. Universities are investing more and promoting administrative software at the expense of Learning Management Systems (LMS) software that supports teaching and learning. This study recommends that professional development programs with emphasis on e-learning pedagogies as well as the establishment of e-learning support structures should be promoted.
Challenges of Educators in the Context of Education Reform and Unrest: A Study of Southern Border Provinces in Thailand

This qualitative study aimed to identify challenges of educators faced with education reform and violent unrest that has taken place in five Southern provinces of Thailand, as well as leadership characteristics that emerged in this context. Participants were 21 educators from primary schools in Pattani, Yala, Narathiwat, Songkhla and Satun provinces. A purposeful selection was employed for participant recruitment of the study. Data collection methods were semi-structured interviews and related official document analysis. The study revealed that challenges of educators related to education reform were managing curriculum, increasing students’ reading competency, coping with work overloads, and managing limited budgets. Challenges related to social unrest were dealing with instructional management, coping with feelings, and ensuring safety. Leadership characteristics that emerged in response to these challenges were becoming patient, dedicated, and adaptive; guiding changes in instructional methods; and building collaborations with related stakeholders.
Spatial evolution of a q-Gaussian laser beam in relativistic plasma

In a recent experimental study, the beam intensity profile of the Vulcan petawatt laser beam was measured; it was found that only 20% of the energy was contained within the full width at half maximum of 6.9 μm and 50% within 16 μm, suggesting a long-tailed non-Gaussian transverse beam profile. A q-Gaussian distribution function was suggested therein to reproduce this behavior. The spatial beam profile dynamics of a q-Gaussian laser beam propagating in relativistic plasma is investigated in this article. A non-paraxial theory is employed, taking into account nonlinearity via the relativistic decrease of the plasma frequency. We have studied analytically and numerically the dynamics of a relativistically guided beam and its dependence on the q-parameter. Numerical simulation results are shown to trace the dependence of the focusing length on the q-Gaussian profile.
Cyclical asymmetry in fiscal policy, debt accumulation and the Treaty of Maastricht

In this paper we present a stylised framework of fiscal policy determination that considers both structural targets and cyclical factors. Applying this framework to a sample of 16 OECD countries, we find evidence of significant asymmetry in the reaction of fiscal policy to positive and negative cyclical conditions, with budgetary balances deteriorating in contractions and not improving in expansions. This asymmetry appears to have contributed significantly to debt accumulation. We find no evidence that EU fiscal rules have reduced the ability of governments to conduct stabilisation policy between 1992 and 2000.
Assessment of Root Plate Structure in Wind-Thrown Trees of Melia dubia

Root plays a significant role in tree growth and development and information pertaining to spread of the root and its depth will be useful for establishing plantations. Most of the root studies are generally carried out in trees growing in urban areas in avenues, but limited studies are carried out in plantations. Being an underground part of the tree, there are inherent difficulties in understanding root architecture. Uprooting of trees due to storm or wind damage provides an ideal opportunity to obtain critical understanding about tree roots. Such study has been carried out in an 11 year old storm ravaged Melia dubia plantation in Punjab, India. Field observations such as tree girth, root girth, root plate width and depth was recorded on uprooted trees. A large variability was recorded for all the traits. Root plate width and depth ranged from 1.42 to 5.17 m and 0.75 to 2.50 m, respectively. A strong positive relationship between tree girth and primary root girth, root plate width and depth identified in this study provides base line information which can be used while establishing M. dubia plantations.Keywords: Melia dubia, root plate, root width, root depth, wind-thrown
The Effects of Iron ( Fe + 3 ) on The Expression Levels of Heat Stress Protein Genes in Rat Liver ( Rattus norvegicus ) Tissue Demir İyonunun ( Fe 3 + ) Sıçan ( Rattus norvegicus )

Iron, one of the most common metals in the world, is important for organisms. It is known that at high concentrations, it damages especially organs such as liver, pancreas, heart. In our study, the effect of iron ion on the expression of the 70 kDa HSP gene family which small stress proteins was investigated in Rattus norvegicus. In this study, iron ion Fe3 + (0,87ppm, 3ppm, 30ppm, 300ppm) was given to 5 different application groups at different concentrations. At the end of this application period, a cDNA library was formed from the liver tissues taken from the living body. Using these libraries, changes in expression levels occurring in the HSP70 (Hspa1a, Hspa4, Hspa5) HSP90 (Hsp90aa1) genes were determined by Real-Time PCR method.
Emergency Department Staffing : A Separated Continuous Linear Programming Approach

The emergency department (ED) overcrowding is becoming serious in recent years. The shortage of ED staff is considered to be a common factor to contribute to the ED overcrowding. In this paper, we present a new model to address the ED staffing from a macroscopic perspective. The model is a kind of optimization model called separated continuous linear programming (SCLP). By using the efficient algorithm for SCLP, we can get the ED staffing level which minimizes the total cost of the patients and the ED.
Lysine requirement for tambaqui juveniles Exigência de lisina para juvenis de tambaqui

The aim of this study was to determine the requirement for lysine in the diet of juvenile tambaqui (Colossoma macropomum). In total, 750 juvenile fish (0.34 ± 0.02g) were distributed in tanks arranged in a randomized block design with six treatments, five replications in two blocks, and 25 fish per unit, for 50 d. Six levels of digestible lysine were tested (1.30, 1.48, 1.66, 1.84, 2.02, and 2.20%), in formulated diets based on the ideal protein concept. The performance, feed efficiency, daily deposition of protein and body fat, and nitrogen retention efficiency of the fish were evaluated. The consumption of rations and protein, specific growth rate, body composition, and deposition of body fat were not influenced by the lysine levels tested. The consumption of digestible lysine increased linearly and the efficiency of digestible lysine for weight gain decreased linearly with the increase in lysine levels. The levels of digestible lysine that optimized weight gain and body protein deposition were estimated at 1.73 and 1.78%, respectively. The feed conversion and nitrogen retention efficiency were most improved at 1.66% and 1.84%, respectively. The recommended level of dietary lysine for providing better weight gain and body protein deposition in juvenile tambaqui is 1.78%, equivalent to 2.00% total lysine.
Update 2013: the Role of Probiotic in Non-alcoholic Fatty Liver Disease, an Evidence Based Approach

During the last two decades, non-alcoholic fatty liver disease (NAFLD) has been a topic in many discussions. The major risk factors for NAFLD is metabolic syndrome, which include obesity, insulin resistance and hypertension. Beside insulin resistance, oxidative stress has been linked with the disease. There is accumulating evidence that intestinal bacterial overgrowth plays an important role in NAFLD pathogenesis. Intestinal bacteria influence the progression of NAFLD through endogenous ethanol production and cytokine that would eventually induce hepatic oxidative stress. Probiotic intervene pathogenic intestinal flora so it is a potential treatment for NAFLD. Many animal studies documented the beneficial effect of probiotic in NAFLD. Probiotic reduce hepatic inflammation, reduce hepatic steatosis and improve insulin resistance. There is still limited human studies upon this topic. However, preliminary result showed potential role of probiotic in NAFLD treatment. Probiotic is safe, cheap and widely available therefore it is a promising new approach for NAFLD therapy. Upcoming study would hopefully provide firm foundation regarding the use of probiotic for NAFLD on human. Keywords: NAFLD, probiotic, metabolic syndrome

OF MASONRY STRUCTURES UNDER EARTHQUAKE EXCITATION UTILIZING MACHINE LEARNING ALGORITHMS

This work aims to analyze and reveal critical features of the papers published since 1990 on the topic of masonry structures under earthquake loading. In particular, detailed information for nearly three thousand papers (exactly 2909) was extracted from the Scopus database [1], and investigated in two stages. Initially, the papers were analyzed in terms of simple statistics and keyword time series – as either raw or normalized data – in order to describe the evolution of the relevant research during the past twenty-seven years (1990-2016, inclusive). In a second phase, bibliometric maps of the papers were developed, regarding their similarities with respect to a variety of the papers’ characteristics such as: author keywords and author names. The resulting diagrams constitute comprehensive maps of the relevant literature, with respect to the associations among the particular characteristics. The bibliometric maps were constructed based on a rigorous methodology, which converts each item (for example, keyword) to a two-dimensional (x, y) point on the bibliometric map. These distances between items reflect the dissimilarities between them, for a particular characteristic. The numerical procedure involved in the construction of the map is a constrained optimization problem which was formulated and solved with an efficient methodology. 2685 Available online at www.eccomasproceedia. org Eccomas Proceedia COMPDYN (2017) 2685-2694 © 2017 The Authors.

Project Management In Industry

This study sought to identify from the Stage-Gate methodology proposed by Cooper in industry that there are similarities with Stage-Gate methodology and make the identification as in the operation of project management in company. Then from a discussion of the subject and the theoretical framework of Stage-Gate was conducted a qualitative case study with a descriptive showing how the industry performs the management of their projects. The industry studied was founded around the year 50 in a municipality of Serra Gaucha, which initially was considered a medium sized company with approximately 320 employees and a production capacity of 200 tons month of its main products used to supply sectors auto parts and agricultural machinery and implements. The data collection was carried from semi-structured interview with a manager of the company. Analyzing the data and observation of documents provided by the company could realize that this company uses a formal system for carrying out development projects and new products or new improvements in their areas and that these have a sequence that resembles the proposal by Cooper. The results demonstrates that the processes of project management when they are supported by an organizational environment that follow the definitions of the teams that lead to new systems, both in content as in organizational processes, and establish interfaces between the various levels of the organization will also assist in procedures and may serve as a strategic lever for the implementation of new ideas in the organization, they enable a better use of company resources.The projects undertaken by the company in study involve from improvements in the workplace, reducing risks of accidents at work or improving the quality of life of employees, to large changes that result in new products, improved profitability in their areas and increases the degree of competitiveness of the company.
Performance Evaluation of Religious Funds

This exploratory study uses monthly net return data from August 2008 to June 2015 on 5 actively managed religious funds to distinguish between luck and skill of fund managers. The main benchmark of this study is the Fama-French-five-factor-model (2013). First, the abnormal performance, alpha, αi, of the equally weighted mutual fund with the above five factor model is examined. Second, we use the bootstrapping simulation approach of Fama and French (2010), to separate manager’s skill from luck. Equally weighted fund exhibits skill.
Compact Circularly Polarized Printed Antenna Using Magnetic Coupling-Fed and Capacitively-Loaded Structure

A compact circularly polarized (CP) printed antenna for global positioning system (GPS) is proposed. The antenna adopts a two-layered stacked structure, in which a diagonally positioned rectangular patch is used as the driven part and capacitively-loaded patch-based crossed dipoles are used as the main radiators. Good impedance matching is obtained conveniently by using magneticcoupling feeding technique, and antenna size reduction is realized by using capacitively-loaded structure (50% size reduction in comparison with the conventional half-wave dipole antennas). A prototype of the antenna with the size of 46mm×46mm is fabricated and tested. Good agreement is achieved between the simulated and measured results, which shows that the impedance bandwidth defined by 10 dB return loss is 34.8 MHz. In addition, the 3 dB-axial-ratio bandwidth is 8 MHz, and the antenna gain is about 7 dB.
