Mesophilic sulfate-reducing bacteria from three deep-sea hydrothermal vent sites

Cette etude a ete entreprise dans le but de determiner la presence et d'etudier la physiologie de bacteries sulfato-reductrices mesophiles (BSR) dans les sources hydrothermales oceaniques, ecosystemes dependant principalement d'une production primaire locale assuree par des micro-organismes chimio-autotrophes. Des BSR ont ete cultivees et isolees d'echantillons de fluides hydrothermaux, d'invertebres, de cheminees et de sediments collectes sur les sites profonds (1700 a 2600 m) du Bassin de Lau, du Bassin nord-Fidjien et de 13°N sur la ride du Pacifique oriental. Des BSR ont ete cultivees a 30°C a partir de 19 echantillons (sur 21), y compris cinq echantillons de fluides hydrothermaux a haute temperature (> 100°C) recoltes dans le Bassin de Lau et le Bassin nord-Fidjien. Ces BSR peuvent utiliser l'acetate, le benzoate, le formate, l'isobutyrate ou le lactate, fournis individuellement comme donneurs d'electrons. Des cultures de BSR ont ete obtenues a 20 et 40°C pour sept des 20 echantillons recoltes sur le site de 13°N. Deux souches utilisant le lactate (Desulfovibrio sp.) ont ete isolees de tubes du Polychete Alvinella sp. Ces souches, H 2.5 and H 5.3, ont un optimum de temperature a 37 a 40°C avec des temps de doublement de 3,6 et 6,6 heures. Dans les cultures de H 2.5 qui ont atteint la phase stationnaire, la presque totalite de la population (> 99 %) devient pleomorphe (formes coccoides). Cependant, des cellules de forme vibrioide sont a nouveau observees apres transfert d'un inoculum dans du milieu frais. Aucun changement significatif dans la composition d'acides gras derives des phospholipides membranaires n'a ete observe lors des transformations morphologiques. Dans les sources hydrothermales profondes, les BSR mesophiles sont frequentes et peuvent se developper dans les habitats anoxiques, associes aux communautes animales liees aux sources chaudes.

Economic burden of patients with inoperable advanced breast cancer receiving early or late capecitabine or trastuzumab as second-line treatment : A population-based study

This study investigates the economic burden and healthcare resource utilization of receiving early or late capecitabine and trastuzumab as second-line anthracyclineor taxane-based treatments for inoperable advanced breast cancer (IABC). Data was retrieved from the National Health Insurance Research Database of Taiwan. The demographic characteristics, healthcare resource utilization, and economic burden of patients with IABC receiving capecitabine and trastuzumab for 0–3, 3–6, 6–9 and 9–12 months after anthracyclineor taxane-based treatments were analyzed. 1,629 women newly diagnosed with IABC were recruited. IABC incidence rates reduced from 9.75% in 2004 to 7.35% in 2006. However, the proportion of patients receiving capecitabine or trastuzumab after anthracyclineor taxane-based treatments increased. Inpatient admissions (times/year), length of hospital stay (days/year), and outpatient visits (visits/year) did not differ significantly for the 2004–2005, 2005–2006 and 2006–2007 cohorts of patients with IABC receiving capecitabine and trastuzumab at different time points. The 1-year healthcare cost and outpatient, inpatient, and total costs (USD/year) differed significantly for trastuzumab but not for capecitabine. The conclusion indicated that early or late capecitabine or trastuzumab administration after first-line anthracycline or taxane-based treatments did not exhibit a change in healthcare resource utilization. In addition, the 1-year healthcare costs did not differ significantly for patients with IABC receiving early or late capecitabine. However, patients with IABC receiving trastuzumab continue to face an economic burden.
Cohesion and Competition of Europe: Innovation Policy from the Perspective of Networks and Entropy

This study analyzes the innovative potential of the European Union in the context of the European Research Area (ERA). Literature related to the Systems of Innovation, network studies, Framework Programs and the European Research Area will be used to establish a theoretical framework for policy analysis. It forms a database from three different resources to establish a European Research and Innovation Network, which appears as a result of policy and program implementation at the European level. The evaluation of the European Union’s innovative potential is discussed for developing policy recommendations, which are derived from theoretical arguments as well as analytical studies, based on network analysis and the notion of entropy. The implementation of a relatively simple rule by the European Commission, in addition to policies focusing on the development of countries’ diversity and absorptive capacity, which are structural breakdowns, may make an important contribution to improving cohesion and competition within the European Research Area, as well innovation in the European Union.
The Impact of Seed Policy Reforms and Intellectual Property Rights on Crop Productivity in India

The growth of private investment in developing-country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy-makers, corporate decision-makers and other actors in the agricultural sector. But there are still unanswered questions about whether emerging and evolving seed policy reforms and IPR regimes in developing countries will contribute to increasing crop productivity and improving food security. This paper attempts to answer some of these questions by focusing specifically on the case of India, the regional leader in implementing seed policy reforms and IPRs in agriculture. Findings indicate that maize and pearl millet yields grew significantly during the last two decades due partly to the combination of (1) public policies that encouraged private investment in India’s seed industry during the 1980s, and (2) biological IPRs conferred by hybridisation that conveniently married the private sector’s need for appropriability with the nation’s need for productivity growth. Although past lessons are not an indication of future success, this convergence of policy solutions and technology opportunities can be replicated for other crops that are vital to India’s food security.
Frame of Reference Theory of Self-Concept Formation with Academically-Able Students.

Frame of reference theory (Marsh, 1990) proclaims that students make both internal ability comparisons across academic domains and external ability comparisons relative to peers indetermining academic self-concept. The validation of this theory with academically-able students seems crucial to their appropriate placement in specialized program options. Verbal and mathematics self-concept and achievement measures were administered to 103 academically able-high school students. Path analyses verified the dual influence of both internal and external processes on overall student self-concepts. Gender difference analyses indicated that whereas males may tend toward making external comparisons, the internal comparison process may be stronger for females. Frame of Reference Theory
Significant year‐round effect of small mixotrophic flagellates on bacterioplankton in an oligotrophic coastal system

The seasonal variation in the grazing effect of mixotrophic flagellates on bacterioplankton was assessed during an annual cycle in an oligotrophic coastal station in the northwest Mediterranean Sea. Ingestion rates of fluorescently labeled bacteria were estimated for different size categories of phytoflagellates (PF) and heterotrophic flagellates (HF) in short‐term experiments and compared with long‐term grazing estimates and published empirical models. The mixotrophic flagellates included haptophyte‐like cells, cryptophytes, and dinoflagellates. The group‐specific grazing rates (SGR) averaged 1.1 (3–5 µm PF), 1.3 (5–20 µm PF), 4.0 (<5 µm HF), and 15.4 bacteria individual−1 h−1 (5‐20 µm HF). Lower SGR but higher abundances of PF resulted in an average mixotroph contribution of 50% to the total flagellate grazing. Remarkably, the effect was relatively high all through the year (35–65%). Regardless of the presence of chloroplasts, flagellates <5 mm in size accounted, on average, for about 80% of total flagellate bacterivory and ingested a large percentage of their cell carbon per day from bacteria. Soluble reactive phosphorus concentration was negatively correlated with the ingestion rate of both groups of PF, suggesting that mixotrophic flagellates would be using their phagotrophic capability to obtain phosphorus when this nutrient is limiting. HF grazing activity showed a marked seasonality, with grazing being higher during the warmer seasons, and clearance rates were positively correlated with water temperature. Total bacterivory accounted for most of the bacterial production. Short‐term and long‐term bacterivory measurements were highly correlated, confirming that the smallest flagellates were the main causative agent of bacterial loss. The bacterivory values were also well correlated to a published empirical model that considers HF as the only bacterivorous. However, this model underestimated (up to 50%) total flagellate grazing during periods of high effect of mixotrophic flagellates.
An exploratory study of the relationship between store image, trust, satisfaction and loyalty in a franchise setting

This study aims to shed insight on how young shoppers, between the ages of 21 and 35, perceive, and relate to, franchise and corporateowned stores in the supermarket industry. This is achieved by investigating the roles of store image, trust and satisfaction in predicting loyalty to a particular store type. By analysing empirical results, this study shows that compared to corporate-owned stores, consumers have an overall better perception of franchise stores, especially in terms of trust and customer satisfaction. Examining an integrative loyalty framework, the study shows diff erential eff ects in how Store Image elements infl uence customer Loyalty indirectly through satisfaction, and how Trust elements infl uence customer Loyalty indirectly through Satisfaction.
The Long-Run Impact of Factors Driving Africa’s Recent Growth Performance: An Empirical Investigation

The paper empirically examined the long-run impact of factors believed to have been driving Africa’s recent growth performance, using the recent analytical methodology, the pooled mean group (PMG) approach, over the period 1980-2013. The results support the narrative that Africa’s recent growth has mainly been driven by improved macroeconomic management associated with improved fiscal consolidation and monetary policy measures being undertaken by most African countries, the demographic influences as a result of increasing working-age population, trade especially as a result of relatively high commodity prices experienced over the period. However, the results show also that foreign debt, inflation rate and FDI (as a greater percentage is directed towards extractive industries) continue to weigh negatively on growth in the long-run.
Soil Temperature Manipulation to Study Global Warming Effects in Arable Land: Performance of Buried Heating-cable Method

Buried heating-cable method for manipulating soil temperature was designed and tested its performance in large concrete lysimeters grown with the wheat crop in Denmark. Soil temperature in heated plots was elevated by 5 o C compared with that in control by burying heating-cable at 0.1 m depth in a plough layer. Temperature sensors were placed at 0.05, 0.1 and 0.25 m depths in soil, and 0.1 m above the soil surface in all plots, which were connected to an automated data logger. Soil-warming setup was able to maintain a mean seasonal temperature difference of 5.0 ± 0.005 o C between heated and control plots at 0.1 m depth while the mean seasonal rise in soil temperature in the top 0.25 m depth (plough layer) was 3 o C. Soil temperature in control plots froze (≤ 0 o C) for 15 and 13 days respectively at 0.05 and 0.1 m depths while it did not in heated plots during the coldest period (Nov-Apr). This study clearly showed the efficacy of buried heating-cable technique in simulating soil temperature, and thus offers a simple, effective and alternative technique to study soil biogeochemical processes under warmer climates. This technique, however, decouples below-ground soil responses from that of above-ground vegetation response as this method heats only the soil. Therefore, using infrared heaters seems to represent natural climate warming (both air and soil) much more closely and may be used for future climate manipulation field studies.
Mechatronic Design of a Lower Limb Exoskeleton

This chapter presents a lower limb exoskeleton mechatronic design. The design aims to be used as a walking support device focused on patients who suffer of partial lower body paralysis due to spine injuries or caused by a stroke. First, the mechanical design is presented and the results are validated through dynamical simulations performed in Autodesk Inventor and MATLAB. Second, a communication network design is proposed in order to establish a secure and fast data link between sensors, actuators, and microprocessors. Finally, patient-exoskeleton system interaction is presented and detailed. Movement generation is performed by means of digital signal processing techniques applied to electromyography (EMG) and electrocardiography (EEG) signals. Such interaction system design is tested and evaluated in MATLAB whose results are presented and explained. A proposal of real-time supervisory control is also presented as a part of the integration of every component of the exoskeleton.
Dynamic Nonmetropolitan Export-base Modeling 117

This paper investigated a time series export-base model of nonmetropolitan Nevada counties. Confirmatory factor analysis was used to bifurcate county employment, and county basic and nonbasic employment were tested for cointegration. Employing the Granger Representation Theorem, an error correction mechanism model was estimated. Error correction mechanism model forecasts were performed and long-run forecasts were evaluated. Given current microcomputer hardware and software, this paper provides a procedure to conduct dynamic rural impact analysis by employing a dynamic export-base model.
Twenty-Six Years of Changes in Education Students’ Attitudes

The main purpose of this quantitative study was to compare graduate education students from 1988 with graduate and undergraduate education students from 2014 in regard to their attitudes and expectations about teaching, schools, and students. The sample of participants for this study was chosen from a large public research university in North Texas and it was comprised of 50 graduate education students from 1988, 119 undergraduate and 147 graduate education students from 2014.The 2014 graduate education students were found to be significantly more negative and to have significantly lower expectations than either the graduate education students of 1988 or the undergraduates of 2014. The 1988 graduate education students were significantly more positive toward their careers than the 2014 undergraduate students. Predictive variables were identified and the possible consequences of increased educators’ negativity toward students and schools are discussed.
Declaration acc . to § 10 Paragraph 11 Common Part of the Master Examination Regulations

This Master thesis investigates the formation and evolution of subglacial drainage systems underneath ice sheets. The presence of water underneath ice masses has enormous effects on ice dynamics as it acts as a lubricant. Ice sheets play a big role in ocean circulation and climate dynamics. So far little is known about the formation and evolution of subglacial water. However, various elements of hydrological systems are suggested to exist ranging from thin water sheets to channels and lakes. This Master thesis attempts to fill this gap and creates a conceptual thermo-mechanical model of ice and water dynamics, which is solved using the finite element method. While the Stokes-equation is used for ice, the Navier-Stokes equation is introduced for the simulation of the water flow. Thus the acceleration terms are included. A coupling of water and ice flow has to overcome the problem that water flows on short time scales while ice on long once. This problem is solved with an adaptive timestepping mode. In order to evolve a water layer the melt rates are calculated by a state of the art enthalpy formulation, using the advantage of solving for temperature and water content at the once. The results demonstrate that it is possible to model both ice and water flow within one approach using the Navier-Stokes flow and the enthalpy formulation. The experiments investigate the effects of geothermal heat flux and inflow velocities on the melt rate behaviour. The results show that thin water layers develop into a channelized flow form when a certain threshold in the water velocity is overcome. Moreover, cavities form in regions of increased geothermal heat flux. With increasing inflow velocity the cavity propagates further in the direction of flow. The results demonstrate a strong relationship between water flow velocities and changes in melt dynamics. Further, it illustrates that the subglacial water system is under constant change. Hence, this study gives an important insight into melt dynamics under ice masses and their evolution.
A study of activation antigens involved in the pathological mechanisms and pathways of cutaneous malignant disease with particular emphasis on cutaneous T cell lymphoma and malignant melanoma.

The investigation of dermatological conditions embraces the concept of a clinicopathological correlation. The studies into cutaneous T cell lymphoma (CTCL) and malignant melanoma (MM), presented here involved predominantly immunocytochemical procedures and relate to the investigations into AP-1 protein expression in CTCL and melanocyte activation antigens in MM. Results: Findings indicate that expression of AP-1 proteins differs not only according to type of CTCL but also according to stages of tumour progression. In MM activation antigen expression varies with tumour metastasis. Consideration of the role of techniques in terms of sensitivity and specificity form a pivitol component in the evaluation of tumour antigen expression.
Forward waveform modelling procedure for 1‐D crustal velocity structure and its application to the southern Korean Peninsula

SUMMARY We propose a full-grid search procedure for broad-band waveform modelling to determine a 1-D crustal velocity model. The velocity model can be more constrained because of the use of broad-band waveforms instead of traveltimes for the crustal phases, although only a small number of event–station pairs were employed. Despite the time-consuming nature of the full-grid search method to search the whole model parameter space, the use of an empirical relationship between the P- and S-wave velocities can significantly reduce computation time. The proposed method was applied to a case in the southern Korean Peninsula. Broad-band waveforms obtained from two inland earthquakes that occurred on 2007 January 20 (Mw 4.6) and 2004 April 26 (Mw 3.6) were used to test the method. The three-layers over half-space crustal velocity model of the P- and S-wave velocities was estimated. Comparisons of waveform fitness between the final model and previously published models demonstrate advancements in the average value of waveform fitness for the inland earthquakes. In addition, 1-D velocity models were determined for three distinct tectonic regions, namely, the Gyonggi Massif, the Okcheon Belt and the Gyeongsang Basin, which are all located inside the study area. A comparison between the three models demonstrates that the crustal thickness of the southern Korean Peninsula increases from NW to SE and that the lower crustal composition of the Okcheon belt differs from that of the other tectonic regions.
PARALLEL SECTIONS HOMOTHETY BODIES WITH MINIMAL MAHLER VOLUME IN ℝn

Abstract. In the paper, we deﬁne a class of convex bodies in R n –parallelsections homothety bodies, and for some special parallel sections homoth-ety bodies, we prove that n-cubes have the minimal Mahler volume. 1. IntroductionThe well-known Mahler’s conjecture (see, e.g., [8], [15], [25] for references)states that, for any origin-symmetric convex body K in R n ,P(K) ≥ P(C n ) =4 n n! (1.1) ,where C n is an n-cube and P(K) = Vol(K)Vol(K ∗ ), which is known as theMahler volume of K.For n = 2, Mahler [16] himself proved the conjecture, and in 1986 Reisner[22] showed that equality holds only for parallelograms. For n = 2, a newproof of inequality (1.1) was obtained by Campi and Gronchi [4]. Recently,Lin and Leng [12] gave a new and intuitive proof of the inequality (1.1) inR 2 . Reisner (see, e.g., [9, 21, 22]) established the same inequality for a class ofbodies that have a high degree of symmetry, known as zonoids. Inequality (1.1)was established by Saint Raymond [24] for bodies which are symmetric withrespect to the coordinate hyperplanes. For the case of polytopes with at most2n+2 vertices (or facets) (see, e.g., [2] for references), Lopez and Reisner [13]proved the inequality (1.1) for n ≤ 8 and the minimal bodies are characterized.Recently, Nazarov, Petrov, Ryabogin and Zvavitch [20] proved that the cube isa strict local minimizer for the Mahler volume in the class of origin-symmetricconvex bodies endowed with the Banach-Mazur distance.
