Inhibitory effects of a manganese superoxide dismutase isolated from garlic (Allium sativum L.) on in vitro tumoral cell growth

Reactive oxygen species are implicated in cancer development and antioxidants in general and superoxide dismutases and superoxide dismutase mimetic in particular, and they inhibit malignant transformation. We examinate the effects of an isolated manganese superoxide dismutase from a medicinal plant Allium sativum. The protein was prepared by a serial of chromatographic techniques: gel filtration and diethylaminoethyl ions exchanger. The enzyme has a specific activity equal to 55 U/mg. Two tumoral cell lines, porcine endothelial cells and mouse melanoma cells were exposed to garlic superoxide dismutase. The exogenous manganese superoxide dismutase is able to modify the intracellular level of reactive oxygen species by eliminating superoxide anion and producing hydrogen peroxide. The cell viability of the two lines was not significantly affected but the cell multiplication was arrested. This effect obtained in the presence of manganese superoxide dismutase correlates with the activation and modulation of phospho‐extracellular signal‐regulated kinases proteins, implicated in the control of several biological processes including cell proliferation. © 2009 American Institute of Chemical Engineers Biotechnol.

Flux Upper Limit on Gamma-Ray Emission by GRB 050713a from MAGIC Telescope Observations

The long-duration γ-ray burst GRB 050713a was observed by the MAGIC Telescope 40 s after the burst onset and followed up for 37 minutes, until twilight. The observation, triggered by a Swift alert, covered energies above ≈175 GeV. Using standard MAGIC analysis, no evidence of a γ-ray signal was found. As the redshift of the GRB was not measured directly, the flux upper limit estimated by MAGIC is still compatible with the assumption of an unbroken power-law spectrum extending from a few hundred keV to our energy range.
Effect of different angle scanning on density estimation based on hounsfield unit on CT and CBCT

This study aim to evaluate the effect of different angle on bone density estimation based on HU on CT and CBCT scanning. A phantom of jaw was scanned using CT and CBCT machine from different angle (0, 15 and 30 degrees). The data were transformed into DICOM format and loaded into MIMICS software for density measurement. The density was measured at 9.55 mm from cemento-enamel junction (CEJ) on every different angle scanning data. Then these data were grouped as Group A1, A2 and A3 for CBCT group (0, 15 and 30 degrees, respectively) and Group B1, B2 and B3 for CT group (0, 15 and 30 degrees, respectively). The differences between the groups and the references (0 degree scanning) are measured statistically using SPSS software. In the CBCT data, the density reading at 15 and 30 degrees are higher than 0 degree scanning (mean difference =-155.63+62.61, p=0.03, mean difference =-33.13+84.24, p=0.206 for 15 and 30 degrees scanning, respectively). In the CT data, the density at 15 and 30 degrees scanning is lower than at 0 degrees scanning (mean different: 84.49+46.76, p=0.09 and 15.09+23.61, p=0.532). The differences are not significant statistically. Compared with CT, the effect of different angle scanning on density estimation on CBCT is stronger. These results showed that different angle scanning produce more error on density estimation based on HU on CBCT compared with CT. This study demonstrated that the uses of a CBCT and CT for density monitoring to evaluate bone density of jaws are affected by angle scanning.

Estimation des incertitudes et prévision des risques en qualité de l'air

Ce travail porte sur l'estimation des incertitudes et la prevision de risques en qualite de l'air. Il consiste dans un premier temps a construire un ensemble de simulations de la qualite de l'air qui prend en compte toutes les incertitudes liees a la modelisation de la qualite de l'air. Des ensembles de simulations photochimiques a l'echelle continentale ou regionale sont generes automatiquement. Ensuite, les ensembles generes sont calibres par une methode d'optimisation combinatoire qui selectionne un sous-ensemble representatif de l'incertitude ou performant (fiabilite et resolution) pour des previsions probabilistes. Ainsi, il est possible d'estimer et de prevoir des champs d'incertitude sur les concentrations d'ozone ou de dioxyde d'azote, ou encore d'ameliorer la fiabilite des previsions de depassement de seuil. Cette approche est ensuite comparee avec la calibration d'un ensemble Monte Carlo. Ce dernier, moins disperse, est moins representatif de l'incertitude. Enfin, on a pu estimer la part des erreurs de mesure, de representativite et de modelisation de la qualite de l'air
Wavelet Neural Network Observer Based Adaptive Tracking Control for a Class of Uncertain Nonlinear Delayed Systems Using Reinforcement Learning

This paper is concerned with the observer designing problem for a class of uncertain delayed nonlinear systems using reinforcement learning. Reinforcement learning is used via two Wavelet Neural networks (WNN), critic WNN and action WNN, which are combined to form an adaptive WNN controller. The "strategic" utility function is approximated by the critic WNN and is minimized by the action WNN. Adaptation laws are developed for the online tuning of wavelets parameters. By Lyapunov approach, the uniformly ultimate boundedness of the closed-loop tracking error is verified. Finally, a simulation example is shown to verify the effectiveness and performance of the proposed method.
Gabor feature extraction for electrocardiogram signals

In this paper, the useful features for clinical diagnosis from electrocardiogram (ECG) signals have been extracted to speed up the diagnosis decision from doctors. Based on the background information of ECG signals, after analyzing some presented methods for ECG feature extraction, algorithm for each feature extraction have been proposed. The major methods for feature extraction we proposed contain short-time Fourier transform (STFT), Gabor filter, and matching process using Gaussian models with various scales. According to the experimental results, less comparative error shows that the proposed algorithm surpasses state-of-arts as stated in the literature for extracting features on ECG signals.
Phase III results with a totally implantable piezoelectric middle ear implant: Speech audiometry, spatial hearing and psychosocial adjustment

Objective To evaluate the treatment efficacy of an electromechanical middle ear amplifier implant (AI) in patients with chronic moderate-to-severe sensorineural hearing loss (SNHL). The AI is a piezoelectric system with a sound processor and a rechargeable battery within a hermetically sealed titanium canister. Its titanium-sealed microphone is placed in the bony region of the ear canal. The incus-coupled transducer (actuator), which is also inside a titanium casing, is fastened to the adjacent bone. Material and Methods This was a phase III study comprising 20 intention-to-treat patients. Telemetrical adjustments followed electromechanical amplifier implantations. We used a word recognition test as our primary efficacy measure (Freiburg Speech Recognition Test; DIN 45621). Secondary efficacy measures were the sentence comprehension test (Goettinger Satztest, 1996) for auditory orientation within noisy and quiet environments and a psychosocial adjustment test (Gothenburg Profile Test, 1998). The 6-month follow-up comprised a complete medical examination. Nineteen patients completed the study (per-protocol patients; 100% reference). Results Seventeen patients (89%) demonstrated improved binaural recognition of phonetically balanced monosyllables. Fourteen postoperative patients (74%) attained a perfect score (100%) on this test, compared to only 3 preoperative patients (16%). Thirteen patients (68%) reached the sentence recognition threshold at a 2:1 dB signal-to-noise ratio during noisy trials. Correct identification of the noise source direction in the horizontal plane occurred in 89% of the trials. The Gothenburg Profile Test scores showed that the subjective evaluation of hearing, orientation, social behavior and self-confidence increased from 48% to 88%. Three patients did not benefit from the implant. Conclusion Treatment of SNHL with a totally implantable hearing system can be an efficient method for those patients unable to wear hearing aids. However, in order to avoid implantation in non-responders, there is a need for more specific audiological indication criteria.
Four Derivations of the Black Scholes PDE

We have written S = S(t); B = B(t); V = V (t) and dW = dW (t) for notational convenience. We also assume the portfolios are self- nancing, which implies that changes in portfolio value are due to changes in the value of the three instruments, and nothing else. Under this setup, any of the instruments can be replicated by forming a replicating portfolio of the other two instruments, using the correct weights.
The Implications of Mandatory Corporate Social Responsibility—A Literature Review Perspective

The purpose of this paper is to discuss the implications of mandatory corporate social responsibility (CSR) contributions: the CSR levy. Using public interest theory as the theoretical lens, this paper adopts a pro-regulation approach and justifies the introduction of the CSR levy in Mauritius, based on the economic and business environment prevailing at the time. Secondary literature sources are used to investigate. Two further questions related to mandatory CSR are investigated: Does the CSR levy result in a competitive disadvantage? Does the CSR levy reduce profits? We conclude that the CSR levy does not disadvantage firms due to the uniform amount and its universal application. Furthermore, it can attract Foreign Direct Investment (FDI) and Socially Responsible Investment (SRI). However, the CSR levy does negatively impact on profits but has the potential to pay higher returns in the future if viewed as an investment. This research needs to be complemented by studies that empirically investigate the impacts of the CSR levy on companies and sectors in Mauritius.
On the Compatibility of the Diboson Excess with a gg -Initiated Composite Sector

We propose that recent results by ATLAS and CMS searching for heavy resonances decaying into bosons could be a first hint of a new sector of pure gauge confining physics, possibly linked to the origin of the Higgs as a Composite Higgs. The lightest resonances (glueballs) of this new sector would be neutral, spin-zero, and spin-two, and their behaviour would resemble that of a radion and a massive graviton of extra dimensions. We outline how 13 TeV LHC data could be used to improve sensitivity on this scenario, as well as future characterization during the 13 TeV LHC run.

✓ This report describes a case of chemical meningitis with status epilepticus following intrathecal injection of fluorescein to delineate cerebrospinal fluid rhinorrhea. The patient was treated with parenteral steroids and anticonvulsants and recovered without sequelae. The wisdom of using minimal practical dosages of fluorescein is emphasized.
Impact of Accounting Information System (AIS) on Supply Chain Management Practices in Indonesian Manufacturing Sector

The ultimate objective of the current study is to investigate the role of Accounting Information System (AIS) on supply chain practices in Indonesian manufacturing sector. Five components of AIS including people, procedures, data, software and IT infrastructure were considered to examine the effect of AIS on supply chain. For this purpose, three manufacturing industries were selected, namely; furniture industry, electronic industry and food production industry. Survey method were selected to collect the primary data. Six hypotheses were developed concerning the relationship of AIS, supply chain and manufacturing organization’s performance. All the hypothesis was tested by using PLS-SEM. It is found that all the components of AIS has significant contribution in supply chain performance. It is concluded that AIS is the most important for every organization to get success in supply chain operations. This study is most significant because it is pioneer study which investigated the role of AIS in supply chain performance. Keywords: Supply chain, accounting information system, furniture industry, electronic industry, food production industry.
Towards Ontology-Based Software Architecture Representations

In order to support a community-wide infrastructure for software architecture research and collaboration, an essential requirement is interoperability of architecture descriptions and representations at both syntactic and semantic levels. Previous research efforts in using various architecture description languages (ADL) have not met this requirement in part due to the lack of standardization, supporting tools, and industry acceptance. This paper makes a case for leveraging the Web Ontology Language (OWL) standard from the Semantic Web community as an underpinning medium for architecture representation and interchange. The paper presents a high level framework for modeling software architectures with ontologies that can be used not only for architecture description and maintenance, but also automated reasoning and analysis of architectural concerns. Illustrative examples for some use cases are given using a simple architecture ontology. With its wide adoption and a rich set of supporting tools, the OWL standard can help rally the academic community around a common platform, as well as bridging the gap with the software industry at large.
BAHA: A Novel Approach to Automatic Bug Report Assignment with Topic Modeling and Heterogeneous Network Analysis

We propose an approach called Bug report assignment with topic modeling and heterogeneous network analysis (BAHA) to automatically assign bug reports to developers. Existing studies adopt social network analysis to characterize the collaboration of developers. The networks used in these studies are all homogenous. In real practice of bug resolution, different developers collaborate on different bug reports that makes the homogenous network unable to capture this information. We use heterogeneous network to describe the relations between reporters, bug reports and developers to characterize developers' collaboration. Experiments on Eclipse JDT project show that BAHA outperforms the state of art methods on automatic bug report assignment.
Two decades of describing the unseen majority of aquatic microbial diversity

Aquatic environments harbour large and diverse microbial populations that ensure their functioning and sustainability. In the current context of global change, characterizing microbial diversity has become crucial, and new tools have been developed to overcome the methodological challenges posed by working with microbes in nature. The advent of Sanger sequencing and now next‐generation sequencing technologies has enabled the resolution of microbial communities to an unprecedented degree of precision. However, to correctly interpret microbial diversity and its patterns this revolution must also consider conceptual and methodological matters. This review presents advances, gaps and caveats of these recent approaches when considering microorganisms in aquatic ecosystems. We also discuss potentials and limitations of the available methodologies, from water sampling to sequence analysis, and suggest alternative ways to incorporate results in a conceptual and methodological framework. Together, these methods will allow us to gain an unprecedented understanding of microbial diversity in aquatic ecosystems.
Methode des distributions superficielles de charges pour la modelisation des antennes electriques en plasma homogene, isotrope et maxwellien

La these presente une methode generale pour la modelisation des caracteristiques de n'importe quel type de senseur electrique installe a bord de vehicule spatial pour l'etude des ondes naturelles et le diagnostic du plasma thermique a partir de mesures d'impedance. Nous proposons la methode des distributions reelles et fictives des charges discretes de surface (scd). Cette methode consiste a imposer que toutes les interfaces considerees, y compris les structures conductrices, soient en equilibre electrostatique avec le plasma. Les charges electriques resultantes sont supposees etre distribuees en un nombre fini d'elements, de sorte que chacun d'eux peut etre considere comme une source ponctuelle a des distances plus grandes que la dimension de la maille. Toutes les difficultes de calcul dans l'evaluation de la puissance rayonnee et de l'impedance des dispositifs reels en 3-d, rencontrees avec la methode traditionnelle des transformees de fourier en plasma cinetique, sont ici supprimees car la fonction de green est resolue une bonne fois pour toutes pour une source ponctuelle. Cette methode est applicable a diverses conditions d'interface avec le plasma : structure conductrice transparente (grillagee), corps conducteurs ou dielectriques pleins avec gaine ionique. Apres quelques applications analytiques simples de la theorie pour une bonne comprehension physique, nous donnons les resultats de simulation numerique de dispositifs reels utilises dans des experiences spatiales.
Social Outcomes for Students With and Without Learning Disabilities in Inclusive Classrooms

Social outcomes of students who participated in two different educational settings designed to provide special services for students with learning disabilities (LD) placed full-time within the general education classroom were examined. Participants were 185 thirdthrough sixth-grade students: 59 students with LD, 72 low to average achieving, and 54 high achieving. There was an overall educational setting effect, with students on the consultation/collaborative teaching setting demonstrating more positive outcomes than students in the co-teaching setting on friendship quality and peer acceptance. Students with LD in the consultation/collaborative teaching setting also demonstrated moderate increases in the number of reciprocal friendships from fall to spring. Discussion addresses the positive social outcomes for students with LD and high-achieving students in the consultation/collaborative teaching setting, and the importance of monitoring student progress in all settings.
Size reduction of Log Periodic Dipole Array antenna

In this paper the design, simulation and experimental exploration of a size reduced Log Periodic Dipole Array (LPDA) antenna is presented. A better optimization has been achieved in a wide frequency range by a suitable alteration of different antenna parameters including Boom length, number of elements, characteristic angles (α, Φ) and deserting Impedance considerations. Different size reduced antenna designs are compared without varying other specifications. This paper noticeably illustrates our efforts regarding size reduction of LPDA.
Trauma Exposure and Stress Response: Exploration of Mechanisms of Cause and Effect

Abstract People differ markedly in their risk for developing posttraumatic stress symptoms (PTSS) after exposure to traumatic events. Twin studies suggest that the trauma-PTSS relationship is moderated by genetic and environmental influences. The present study tested for specific types of genetic and environmental interaction effects on PTSS. A sample of 222 monozygotic and 184 dizygotic twin pairs reported on lifetime frequency of assaultive and nonassaultive trauma and associated PTSS. Biometric analyses indicated that in the case of nonassaultive trauma, PTSS were directly affected by environmental factors that also influence exposure to nonassaultive trauma. For assaultive trauma both genetic and non-shared environmental influences jointly affected PTSS, and the number of traumatic events moderated the severity of PTSS. Genetic factors were found to become less important beyond some threshold (e.g., 3 or 4 types of serious trauma) suggesting that genetic factors — which may confer either risk or resilience to PTSS — modify these symptoms within a range of human experience, beyond which environmental effects supervene.
Product types in moderating the process of buying street foods

This study aims to examine the effects of price, quality, and ease in obtaining on positive attitudes and intentions to buy street food moderated by product types (traditional meals and modern meals). The sample consists of 1000 individuals. Multi-group SEM is a statistical tool selected to elaborate the relationships between variables that are conceptualized. The results indicate that before the product type is separated, price and quality are the variables that influence the positive attitude and the intention of buying the traditional food, while the ease of getting not. When this type of product is separated, the results indicate that in snack foods, the price, quality and ease of obtaining are the variables that affect the positive attitude, but do not affect the purchasing intentions. For restaurant food, that price and quality are the variables that influence positive attitude and purchase intention, while not for purchase intention.
Water activity, temperature, and pH effects on growth of the biocontrol agent Pantoea agglomerans CPA-2.

The growth response of the biocontrol agent Pantoea agglomerans to changes in water activity (a(w)), temperature, and pH was determined in vitro in nutrient yeast extract-sucrose medium. The minimum temperature at which P. agglomerans was able to grow was 267-272 kelvins (-6 to -1 degrees C), and growth of P. agglomerans did not change at varying pH levels (4.5-8.6). The minimum a(w) for growth was 0.96 in media modified with glycerol and 0.95 in media modified with NaCl or glucose. Solute used to reduce water activity had a great influence on bacterial growth, especially at unfavourable conditions (e.g., low pH or temperature). NaCl stimulated bacterial growth under optimum temperatures but inhibited it under unfavourable pH conditions (4.5 or 8.6). In contrast, the presence of glucose in the medium allowed P. agglomerans to grow over a broad range of temperature (3-42 degrees C) or pH (5-8.6) regimes. This study has defined the range of environmental conditions (a(w), pH, and temperature) over which the bacteria may be developed for biological control of postharvest diseases.
