Study of stellar populations in the bulges of barred galaxies

Aims. To determine the influence of bars in the building of galaxy bu lges through the analysis of ages and metallicities derived from stellar absorption line-strength indices. Methods. Long-slit spectroscopy was obtained for a sample 20 early-type barred galaxies. Line strength indices were measured and used to derive age and metallicity gradients in the bulge region by comparing with stellar population models. The same analysis was carried out with similar data of unbarred galaxies taken from the literature. Results. The bulges of barred galaxies seem to be more metal rich, at a given velocity dispersion (� ), than the bulges of unbarred galaxies, as measured by some metallicity sensitive indices. There are indications that the ratio of relative abundanc e of alpha-elements with respect to iron, [E/Fe], derived for the bulges of barred galaxies tend to lie above the values of the unbarred galaxies at a given� . The metallicity gradients for the majority of the bulges are negative, less metal rich towards the end of the bulge. The gradient values

Pseudomonas pseudoflava, a New Species of Hydrogen-Oxidizing Bacteria: Its Differentiation from Pseudomonas flava and Other Yellow-Pigmented, Gram-Negative, Hydrogen-Oxidizing Species

Five new strains of yellow-pigmented, gram-negative, motile, hydrogen-oxidizing bacteria were isolated; each served as a host for simultaneously isolated bacteriophages. These isolates and two additional strains were compared with other gram-negative, hydrogen-oxidizing bacteria with respect to morphology; nutritional and biochemical properties; growth parameters; cytochrome content; pigment production; susceptibility to bacteriophages, bacteriostatic agents, and antibiotics; deoxyribonucleic acid base composition; and deoxyribonucleic acid-deoxyribonucleic acid homology. Six of the strains were characterized by a high degree of interstrain similarity and were found to be related to Pseudomonas flava. However, due to basic differences between these strains and P. flava, the former are regarded as comprising a new species for which, because of its moderate relationship to P. flava, the name Pseudomonas pseudoflava is proposed. The type strain of P. pseudoflava, GA3, has been deposited with the Deutsche Sammlung von Mikroorganismen in Gottingen under the number DSM 1034.
Improving the Performance of MPPT on DC Grid PV Systems by Modified Incremental Conductance Algorithm

The performance of photovoltaic (PV) system is affected by temperature, solar insolation, solar panel configuration and shading. In order to succeed maximum efficiency, PV arrays should operate at their maximum power point (MPP). Hence, the MPP tracking (MPPT) unit is implemented among the PV energy conversion system to obtain maximum power. In this study, incremental conductance (IC) algorithm, the most commonly used algorithm in MPPT systems for expectation-maximization, was analysed and an approach towards eliminating ripple problems, improving speed to obtain more power value, were maintained and duty cycle (Dk) value was obtained from IC algorithm under changing PV panel radiation conditions. In the end, it was evaluated alongside with MATLAB simulation results.
Detecting Tax Evasion When Tax and Accounting Earnings Match

The main purpose of the present study is to examine the tax behaviour of listed companies when operating in an accounting environment characterized by a high level of book – tax conformity. According to international practice, tax evasion is estimated by using two different measures: the tax evasion rate and the tax gap. After identifying the extent of tax evasion, a number of financial statement variables are examined in order to assess the financial characteristics of the tax aggressive firms. Companies with higher rates of tax evasion have more liquidity, more debt (especially short-term liabilities), are less effective and efficient in generating earnings and are smaller in size. Companies with higher amounts of tax gap are larger in size, have more liquidity, more debt (especially short-term liabilities) and are more effective. The outcomes of the present study may assist public bodies, such as tax authorities and regulatory bodies, as well as audit firms in detecting and deterring tax evasion.
Prevalence of Liver Cancer in Isfahan Province, Iran

Background: Liver cancer remains to grow worldwide. We aimed to describe the period prevalence (PP) and incidence rates (Irs) for liver cancer in Isfahan Province that is located in the center of Iran and ranked as the third province in terms of population.Methods: Information related to the Surveillance, Epidemiology, and End Results; (SEER) was collected from the Isfahan Cancer Registry. Period prevalence (PP) was calculated per 100,000 people. The cancer sites studied were defined according to the International Classification of Diseases (ICD-O; Third Edition) and recorded by topography code (C22). Result: Among all registered liver cancer patients, 57% of the 920 cases were male. The mean age of the patients was 65.9 ± 16.8 years. Reported age in 13% of the patients was less than 50 years and as high as 84% were in between 50 to 90 years. With a total PP of 18.5 per 100,000 people, this value was 24.4% higher in males when compared to females (16.8 vs. 20.9). In the previous years, incidences were 3.9 (2011-2012), 5.3 (2012-2013), 4.9 (2013-2014) and 4.2 (2014-2015) per 100,000 people. There were 89% reported deaths among the total population.Conclusion: The PP for liver cancer in male population was approximately 24.4% higher than females. There was a 7.7% increase in the Irs over the study period. Further study toward estimation of the proportion of the causes of liver cancer and deaths due to infection of hepatitis B and C virus, exposure to aflatoxin, alcohol drinking and smoking seem to be advantageous. Therefore, the plan of healthcare system should focus on greater effort toward strategic evidence-based pharmacotherapy in Isfahan province/Iran.
Femtosecond Laser Fabrication of Engineered Functional Surfaces Based on Biodegradable Polymer and Biopolymer/Ceramic Composite Thin Films

Surface functionalization introduced by precisely-defined surface structures depended on the surface texture and quality. Laser treatment is an advanced, non-contact technique for improving the biomaterials surface characteristics. In this study, femtosecond laser modification was applied to fabricate diverse structures on biodegradable polymer thin films and their ceramic blends. The influences of key laser processing parameters like laser energy and a number of applied laser pulses (N) over laser-treated surfaces were investigated. The modification of surface roughness was determined by atomic force microscopy (AFM). The surface roughness (Rrms) increased from approximately 0.5 to nearly 3 µm. The roughness changed with increasing laser energy and a number of applied laser pulses (N). The induced morphologies with different laser parameters were compared via Scanning electron microscopy (SEM) and confocal microscopy analysis. The chemical composition of exposed surfaces was examined by FTIR, X-ray photoelectron spectroscopy (XPS), and XRD analysis. This work illustrates the capacity of the laser microstructuring method for surface functionalization with possible applications in improvement of cellular attachment and orientation. Cells exhibited an extended shape along laser-modified surface zones compared to non-structured areas and demonstrated parallel alignment to the created structures. We examined laser-material interaction, microstructural outgrowth, and surface-treatment effect. By comparing the experimental results, it can be summarized that considerable processing quality can be obtained with femtosecond laser structuring.

English teachers’ knowledge for implementing the 2013 Curriculum

The implementation of the 2013 Curriculum as a new curriculum plays an important role in the development of curricula in Indonesia. Some changes in the new curriculum require teachers to have knowledge in spesific areas such as in the standards for content, teaching-learning processes and evaluation. The purpose of this study was to find out the extent of the teachers’ knowledge on standards for content, standards for processes, and standards for evaluation for the 2013 curriculum. To fulfill the purpose of this study, a sample of English teachers was taken from three State Islamic Senior High Schools in Banda Aceh. The data collected was analysed by descriptive quantitative research methods; a questionnaire was used to collect the data. The results showed that the teachers level of knowledge for implementing the 2013 Curriculum was low. This can be seen in the three standards viz: teachers’ knowledge of the standards for content, for the 2013 Curriculum was low, only 40 %; that for standards for processes was also low, 41%, and the teachers’ knowledge about standards for evaluation was the lowest, only 36%. In order to resolve these problems, some recommendations have been made for improvement of the teacher’s knowledge of how to implement the new, 2013 Curriculum.
Identifying Entrepreneurship Indicators for Regional Economic Growth in the New Zealand Context

Despite a rapidly growing literature on spatial aspects of entrepreneurship, the knowledge base on the link between entrepreneurial activities and regional economic growth remains fragmented and incomplete. Using the Business Demography Statistics database by Statistics New Zealand the paper investigates entrepreneurship dynamics, entrepreneurial diversity (defined as immigrant entrepreneurship) and employment growth in 74 Territorial Authorities over the 2001-2005 period. Structural equation models with a set of measured (observed) variables and a set of latent (unobserved) variables are proposed. The empirical findings illustrate that differences in levels of entrepreneurial activity and diversity among entrepreneurs are positively associated with variations in regional employment growth rates, but time lags should be taken into account. Implications of the findings for economic policy makers and politicians are discussed.
Jurnal Teknologi Multivariable PID Using Singularly Perturbed System

The paper investigates the possibilities of using the singularly perturbation method in a multivariable proportional-integral-derivative (MPID) controller design. The MPID methods of Davison, PenttinenKoivo and Maciejowski are implemented and the effective of each method is tested on wastewater treatment plant (WWTP). Basically, this work involves modeling and control. In the modeling part, the original full order system of the WWTP was decomposed to a singularly perturbed system. Approximated slow and fast models of the system were realized based on eigenvalue of the identified system. The estimated models are then used for controller design. Mostly, the conventional MPID considered static inverse matrix, but this singularly perturbed MPID considers dynamic matrix inverse. The stability of the singularly perturbed system is established by using Bode analysis, whereby the bode plot of the model system is compared to the original system. The simulation results showed that the singularly perturbed method can be applied into MPID. The three methods of MPID have been compared and the Maciejowski shows the best closed loop performance.
Asymmetrical meter in Scandinavian folk music and dance - A case study of Norwegian Telespringar

Certain traditional Norwegian and Swedish dance tunes in triple meter are referred to as being in so-called asymmetrical meter—that is, the three beats in the measure are of uneven duration. Norwegian telespringar is recognized for a type of asymmetrical meter featuring a systematic long–medium–short duration pattern at beat level. These systematic microtiming patterns are often described in terms of deviations from an underlying isochronous pulse. However, it has been argued that performers’ body motion may offer a more perceptually relevant structure of reference than an abstract fixed clock pulse. This study investigates whether the asymmetrical beat patterns previously shown in telespringar music are also represented in the body motion of performers who are playing and dancing. It is reported from two motion capture studies: first, a fiddler playing telespringar on a traditional Hardanger fiddle; second, a couple dancing telespringar. Motion analysis of the fiddler’s foot stamping indicates a very regular long–medium–short beat pattern. In addition, the fiddler’s upper-body swaying and the vertical motion of the body’s center of gravity in telespringar dancing are in synchrony with the bar level of the music. The fiddler’s foot stamping confirm the long–medium–short beat duration hypothesis and support the view that the systematic microtiming features in telespringar are not a matter of deviation from an underlying isochronous pulse. Instead, they actually constitute an essential feature of telespringar.

L'Annexine A5 (Anx5) est une proteine de la famille des annexines qui presente la propriete de s'organiser a la surface des bicouches lipidiques en trimeres et en assemblages bidimensionnels (2D) de trimeres. Ce travail de these concerne le developpement d'applications biotechnologiques des assemblages 2D d'Anx5 ainsi qu'une etude des proprietes fonctionnelles de ces assemblages. Ces travaux ont ete realises principalement a l'aide des methodes de la microbalance a cristal de quartz avec mesure de dissipation (QCM-D) et de la microscopie a force atomique (AFM). La premiere partie de cette these concerne le developpement de plates-formes d'ancrage basees sur des assemblages 2D de proteines derivees de l'Anx5. Des complexes covalents entre l'Anx5 et des peptides d'adhesion cellulaire pour la realisation de plates-formes d'ancrage de cellules. Des proteines de fusion entre l'Anx5 et un fragment de la proteine A ont d'autre part servi au developpement de plates-formes 2D pour l'immobilisation controlee d'anticorps et de proteines. La seconde partie de cette these concerne l'etude des proprietes fonctionnelles des assemblages 2D d'Anx5. L'etude de l'interaction d'un anticorps anti-phospholipide avec les assemblages 2D d'Anx5 montre que cet anticorps ne perturbe pas l'organisation 2D de l'Anx5. La seconde etude concernant l'influence des assemblages 2D de l'Anx5 sur la dynamique des bicouches lipidiques etablie une correlation entre la formation de trimeres et le ralentissement de la dynamique des membranes. Ces travaux contribuent a notre comprehension des proprietes des assemblages 2D d'Anx5 et permettent d'envisager le developpement de biocapteurs pour cellules ou molecules.
Mycotoxin bioaccessibility/absorption assessment using in vitro digestion models: a review

In the evaluation of the oral bioavailability of a mycotoxin, the first step is the determination of its bioaccessibility, i.e. the percentage of mycotoxin released from the food matrix during digestion in the gastrointestinal (GI) tract that could be absorbed through the intestinal epithelium. Different in vitro digestion models have been recently used for determination of bioaccessibility, thereby avoiding the use of more complex cell culture techniques or the use of animals in expensive in vivo experiments. In vitro methods offer an appealing alternative to human and animal studies. They usually are rapid, simple and reasonably low in cost, and can be used to perform simplified experiments under uniform and well-controlled conditions, providing insights not achievable in whole animal studies. The available in vitro methods for GI simulation differ in the design of the system, the composition of the physiological juices assayed, as well as in the use or not of intestinal microbiota. There are models that only simulate the upper part of the GI tract (mouth-stomach-small intestine), whereas other methods include the large intestine, so that the model chosen could have some influence on the bioaccessibility data obtained. Bioaccessibility depends on the food matrix, as well as on the contamination level and the way the food/feed is contaminated (spiked or naturally). This review focuses on the currently available data regarding in vitro digestion models for the study of the bioaccessibility or absorption of mycotoxins, detailing the characteristics of each digestion step and the importance of the physiological juices employed during digestion. The effect that different factors play on mycotoxin release from the food matrix in the GI tract is also considered, and existing data on bioaccessibility of the main mycotoxins are given.
Role of Abscisic Acid in Disease Resistance

Plants are sessile organisms, and their only means to respond when exposed to biotic stress such as pathogen attack is to activate rapidly a panoply of reactions, including both physical and chemical defenses. These defensive reactions, which result in the death of the pathogen, are the result of highly coordinated sequential changes at the cellular level comprising, among other changes, the synthesis of salicylic acid (SA), jasmonic acid (JA), ethylene (ET), reactive oxygen species (ROS), and nitric oxide (NO), as well as the hypersensitive reaction (HR; Agrios 2005). Historically, two signaling pathways have been implicated in the amplification and transmission of the signal perceived at the moment a plant recognizes a pathogen until the final defense reactions have been engaged (Kunkel and Brooks 2002). SA has long been recognized as crucial to signal transduction (Ryals et al. 1996), and the importance of a functional JA/ET signaling pathway also rapidly became apparent (Thomma et al. 2001). Although SA signaling in Arabidopsis has been shown to be implicated predominantly in defense against biotrophic or hemibiotrophic organisms, JA/ET-dependent signaling seems to be more important when plants are confronted with necrotrophic organisms (Rojo et al. 1999; Thomma et al. 2001). Because of their involvement and crucial roles in the signal transduction pathways implicated in plant defense against pathogens and insects, SA, JA, and ET have been the most extensively studied hormones. In contrast, the role of other hormones, such as auxins, gibberellins (GAs), abscisic acid (ABA), and brassinosteroids (BR), has been neglected in this context. An increasing body of evidence has recently pointed to interesting and important roles for these hormones in plant defense against biotic stresses (for review, see Robert-Seilaniantz et al. 2007). In this chapter, emphasis is placed on the role of ABA in basal and induced resistance and in priming phenomena against biotic stresses.

ENTROPIC CHARACTERIZATION OF QUANTUM OPERATIONS

We investigate decoherence induced by a quantum channel in terms of minimal output entropy and map entropy. The latter is the von Neumann entropy of the Jamiolkowski state of the channel. Both quantities admit q-Renyi versions. We prove additivity of the map entropy for all q. For the case q = 2, we show that the depolarizing channel has the smallest map entropy among all channels with a given minimal output Renyi entropy of order two. This allows us to characterize pairs of channels such that the output entropy of their tensor product acting on a maximally entangled input state is larger than the sum of the minimal output entropies of the individual channels. We conjecture that for any channel Φ1 acting on a finite dimensional system, there exists a class of channels Φ2 sufficiently close to a unitary map such that additivity of minimal output entropy for Ψ1 ⊗ Ψ2 holds.
