DETECTION OF ENTEROTOXIGENIC STAPHYLOCOCCUS AUREUS IN SOME MEAT PRODUCTS

Received at: 18/3/2013 Accepted: 14/4/2013 Eighty four meat product samples (minced meat, sausage and beef burger 28 of each) were collected and examined for detection of Staphylococcus aureus. The mean count was 4.3x10 2 , 5.1x10 3 and 8.7x10 3 cfu / gm, respectively. Multiplex Polymerase Chain Reaction (PCR) was applied for detection of genes responsible for enterotoxins production from identified coagulase positive Staphylococcus aureus. The predominant genes were A and B. They were detected in examined sausage and beef burger samples with different percentages.
The Intangible-adjusted Book-to-market Ratio

The book-to-market ratio has been widely used to explain the cross-sectional variation in stock returns over the past three decades. However, there is growing evidence that the explanatory power of the ratio has become weaker. I argue that the change is related to the growth of intangible assets unrecorded in balance sheets due to the challenges in accounting for intangibles and propose an intangible-adjusted ratio as an alternative by capitalizing prior expenditures to develop the assets and excluding goodwill. I find that the alternative ratio outperforms the original significantly. The cumulative return on the high-minuslow (HML) portfolio formed on the alternative (original) ratio is 910% (316%) during 1976 – 2017.
57Fe Mössbauer effect study of bannisterite: a modulated 2:1-type phyllosilicate

Abstract Bannisterite is a modulated 2:1-type phyllosilicate having ten octahedral sites with hydroxyl groups in trans, cis and combined trans-cis configurations. Each octahedral site, depending on its proximity to the layer modulation, is exposed to a different degree of distortion. The electric field gradient at the Fe site and the site distortion are used to propose a model for the site assignment and oxidation mechanism in bannisterite. The results show that two models are compatible with the experimental results of fitting the spectrum of bannisterite. However, the model which allows for site distortion accounts better for the observed line overlap of the [6]Fe2+ sites. Accordingly, the octahedral sites with a greater degree of distortion are assigned to the [6]Fe2+ with lower electric quadrupole splitting, and the octahedral sites with lower site distortion are assigned to the [6]Fe2+ with higher electric quadrupole splitting. Moreover, the ease of oxidation decreases in the order trans > trans-cis > cis.
THE PURDUE UNIVERSITY GRADUATE SCHOOL STATEMENT OF THESIS APPROVAL

Ozdemir, Hikmet D. M.S.E.C. E. , Purdue University, August 2020. Evaluation of Model Predictive Control Method for Collision Avoidance of Automated Vehicles. Major Professor: Lingxi Li. Collision avoidance design plays an essential role in autonomous vehicle technology. It’s an attractive research area that will need much experimentation in the future. This research area is very important for providing the maximum safety to automated vehicles, which have to be tested several times under different circumstances for safety before use in real life. This thesis proposes a method for designing and presenting a collision avoidance maneuver by using a model predictive controller with a moving obstacle for automated vehicles. It consists of a plant model, an adaptive MPC controller, and a reference trajectory. The proposed strategy applies a dynamic bicycle model as the plant model, adaptive model predictive controller for the lateral control, and a custom reference trajectory for the scenario design. The model was developed using the Model Predictive Control Toolbox and Automated Driving Toolbox in Matlab. Builtin tools available in Matlab/Simulink were used to verify the modeling approach and analyze the performance of the system. The major contribution of this thesis work was implementing a novel dynamic obstacle avoidance control method for automated vehicles. The study used validated parameters obtained from previous research. The novelty of this research was performing the studies using a MPC based controller instead of a sliding mode controller, that was primarily used in other studies. The results obtained from the study are compared with the validated models. The comparisons consisted of the lateral overlap, lateral error, and steering angle simulation results between the models.

COMSOL Multiphysics® Modeling in Darcian and Non-Darcian Porous Media

Viscous fingering (VF), a hydrodynamic instability, is often observed in porous media when a less mobile fluid is displaced by a more mobile fluid. Depending on the porosity of the medium this can be classified into two classes: Darcian and non-Darcian. The fluid flow in the former is described by the Darcy’s law, whereas in the later different momentum equations are required. Here, we present COMSOL simulations for miscible VF in homogeneous porous media of both types. We use Brinkman equation for modeling in the porous media, wherever Darcy’s law is not applicable. For the modeling purpose, two different physics (hydrodynamics and transport of solute in porous media) are coupled. The Darcy’s law results are in good match with the linear stability as well as nonlinear simulations existing in the literature. Simulation results of the COMSOL multiphysics reveal the similarities and differences between the Darcy’s law and Brinkman equation.
A new modification method of exploded lignin for the preparation of a carbon fiber precursor

A lignin-pitch for carbon fiber was prepared in a high yield from exploded lignin on phenolysis followed by heat treatment under a vacuum. The lignin-pitch had an excellent spinnability in the melt state to form a fine filament. The green fibers were easily made infusible when heated in air at a relatively high heating rate (15-60°C/h). The lignin-based carbon fiber was produced in 43.7% of yield based on a starting material. The tensile strength was more than 400 MPa, indicating that the lignin-based carbon fiber is classified into a general purpose grade. © 1993 John Wiley & Sons, Inc.
Understanding Characteristics of Popular Streamers on Live Streaming Platforms: Evidence from Twitch.tv

Live streaming platforms such as Twitch and Periscope have become some of the most popular synchronous social networking services. To attract viewers, streamers are motivated to broadcast exciting video content while actively interacting with viewers. The emerging stream of research on the live streaming community has examined streamers’ motivations and how the viewers react to streamers. However, few studies have focused on understanding the characteristics of popular streamers. Popular streamers create tremendous business value for social media influencer investors, as they have high potential to create persuasive advertisements and endorsements for firms by promoting their products and services. We aim at examining the key characteristics associated with streamers’ viewer base, namely their personality, professionalism, and streaming affordance. Based on text mining and analyses of video content, our results show: (1) certain personality traits (such as openness) are negatively associated with both cumulative and current popularity, (2) professional players are more likely to attract a larger viewer base, and (3) social affordance, including profile building affordance, social connectivity, and social interactivity, is positively associated with both cumulative and current popularity. Our results provide useful insights into measuring and evaluating streamers’ popularity, which can, in turn, generate actionable strategies for social media influencer investors and platform operators.
Students as Designers of E-book for Authentic Assessment

Purpose â€“ The purpose of this study is to examine the elements that determine studentsâ€™ success as designers of an e-book by means of an authentic assessment in a collaborative learning environment. A total of 11 English Language Teaching (ELT) postgraduate students were involved as designers, writers and peer reviewers of the e-book project. Methodology â€“ Data was gathered based on a qualitative methodological approach, via face-to-face discussions, WhatsApp groups, Moodle classes and reflections from studentsâ€™ e-portfolios. The data was analyzed using content analysis procedures where it was read carefully to understand emerging themes. It was then coded and labeled manually in relation to the aims of the study and its theoretical framework. Findings â€“ The analysis suggested that the students had positive experiences where they became self-publishers while engaged in designing learning experiences via integrating technology. The use of authentic assessments enabled them to develop teamwork, to become motivated and self-directed learners with autonomy. Significance â€“ The outcome of this research will help course designers and program developers to integrate authentic assessments that are relevant to the current needs of students.
Long-term characterization of trihalomethane levels in drinking water

Water chlorination leads to the formation of trihalomethanes (THM). In this case study, the levels of THM during the chlorination process of the drinking water in Valencia (Spain) were determined over a 12-year period. Different control areas and points were strategically sampled and samples were analyzed by gas chromatography. Temporal tendencies, as well as spatial and seasonal variations, were established. The individual distribution of THM was also evaluated. Factors such as distances from chlorination points and inter-month seasonal distribution, including ambient temperature effect, were assessed. The range of total THM concentrations measured in the water network goes from 4 to 184 µg L−1. However, from the year 2000, coinciding with an improvement in the quality scheme of the analytical method, no more than one sample per year is above the limiting level of 100 µg L−1 and the annual data dispersion becomes lower. Although the levels of THM virtually do not exceed the limits established by law, the variability in their concentrations suggests the need for adaptable control plans combined with factors such as ambient temperature and distances from disinfection points.
Recognition of Emotional States Using Multiscale Information Analysis of High Frequency EEG Oscillations

Exploring the manifestation of emotion in electroencephalogram (EEG) signals is helpful for improving the accuracy of emotion recognition. This paper introduced the novel features based on the multiscale information analysis (MIA) of EEG signals for distinguishing emotional states in four dimensions based on Russell’s circumplex model. The algorithms were applied to extract features on the DEAP database, which included multiscale EEG complexity index in the time domain, and ensemble empirical mode decomposition enhanced energy and fuzzy entropy in the frequency domain. The support vector machine and cross validation method were applied to assess classification accuracy. The classification performance of MIA methods (accuracy = 62.01%, precision = 62.03%, recall/sensitivity = 60.51%, and specificity = 82.80%) was much higher than classical methods (accuracy = 43.98%, precision = 43.81%, recall/sensitivity = 41.86%, and specificity = 70.50%), which extracted features contain similar energy based on a discrete wavelet transform, fractal dimension, and sample entropy. In this study, we found that emotion recognition is more associated with high frequency oscillations (51–100Hz) of EEG signals rather than low frequency oscillations (0.3–49Hz), and the significance of the frontal and temporal regions are higher than other regions. Such information has predictive power and may provide more insights into analyzing the multiscale information of high frequency oscillations in EEG signals.
Quality of mango fruits during storage: effect of synthetic and eco-friendly films

Mango (Mangifera indica) cv ‘Alphonso’ fruits, harvested 40–50 days after flowering, were stored at 27 ± 1 ◦C and 65% RH under three conditions of packaging: (1) perforated plastic boxes, (2) wax lined cartons sealed with low-density polyethylene (LDPE) film, and (3) wax lined cartons sealed with chitosan films. The weight loss, firmness, Hunter colour values and acidity were determined periodically during storage. Sensory analysis was carried out to determine colour, firmness, flavour qualities and also defective spots. Principal component analysis (PCA) of the results indicated that fruits stored in perforated plastic boxes and LDPE film-sealed cartons differed significantly with respect to mango flavour, firmness and development of defective spots, while those in chitosan film sealed cartons retained the desirable qualities for a longer period (up to 20 days) without developing defective spots. The higher level of carbon dioxide and lower level of oxygen, or lower rate of oxygen transmission, associated with chitosan films delay ripening, and the higher water vapour transmission rate minimizes the rate of transpiration and prevents condensation of water droplets on the film. This helps in establishing equilibrium moisture content of mangoes in the cartons, which, in turn, extends the shelf life of fruits for a longer period.
Wavelength dependence of the quantum yield of fluorescence and photoionization of indoles

The fluorescence quantum yields φf (λx) of L‐tryptophan and indole were measured relative to that of Rhodamine B as functions of the excitation wavelength λx between 200 and 300 nm. Two different experimental geometries produced identical results, indicating that experimental artifacts were negligible. In aqueous solution at 296 K, φf (λx) increased by 45% for both solutes in going from 230 to 260 nm. Outside this wavelength region, φf (λx) was constant to within 2%. Similar results, although with a somewhat smaller shift in φf (λx), were obtained for tryptophan in an equivolume mixture of ethylene glycol and water EG/H2O at both 296 and at 113 K, the latter temperature being below the glass transition temperature of this medium. The emission spectra and the phosphorescence to fluorescence ratios were independent of λx, indicating that the shift in φf (λx) was not due to intersystem crossing from higher excited states. The shift in φf (λx) was accompanied by a considerable increase in the quantum yield of.
The large gamma-ray flare of the flat-spectrum radio quasar PKS 0346−27

Aims. In this paper, we characterize the first γ-ray flaring episode of the flat-spectrum radio quasar PKS 0346−27 (z = 0.991), as revealed by Fermi-LAT monitoring data, and the concurrent multi-wavelength variability observed from radio through X-rays. Methods. We studied the long- and short-term flux and spectral variability from PKS 0346−27 by producing γ-ray light curves with different time binning. We complement the Fermi-LAT data with multi-wavelength observations from the Atacama Large Millimeter Array (radio mm-band), the Rapid Eye Mount telescope (near-infrared) and Swift (optical-UV and X-rays). This quasi-simultaneous multi-wavelength coverage allowed us to construct time-resolved spectral energy distributions (SEDs) of PKS 0346−27 and compare the broadband spectral properties of the source between different activity states using a one-zone leptonic emission model. Results. PKS 0346−27 entered an elevated γ-ray activity state starting from the beginning of 2018. The high-state continued throughout the year, displaying the highest fluxes in May 2018. We find evidence of short-time scale variability down to approximately 1.5 h, which constrains the γ-ray emission region to be compact. The extended flaring period was characterized by a persistently harder spectrum with respect to the quiescent state, indicating changes in the broadband spectral properties of the source. This was confirmed by the multi-wavelength observations, which show a shift in the position of the two SED peaks by approximately two orders of magnitude in energy and peak flux value. As a result, the non-thermal jet emission completely outshines the thermal contribution from the dust torus and accretion disk during the high state. The broadband SED of PKS 0346−27 transitions from a typical Low-Synchrotron-Peaked (LSP) to the Intermediate-Synchrotron-Peaked (ISP) class, a behavior previously observed in other flaring γ-ray sources. Our one-zone leptonic emission model of the high-state SEDs constrains the γ-ray emission region to have a lower magnetic field, larger radius, and higher maximum electron Lorentz factors with respect to the quiescent SED. Finally, we note that the bright and hard γ-ray spectrum observed during the peak of flaring activity in May 2018 implies that PKS 0346−27 could be a promising target for future ground-based Cherenkov observatories such as the Cherenkov Telescope Array (CTA). The CTA could detect such a flare in the low-energy tail of its energy range during a high state such as the one observed in May 2018.
Negative differential capacities in electrical double layers

Monte Carlo simulations of an electrical double layer in a primitive model of a 0.05 M 1:2 electrolyte are reported in which the total potential drop across the interface decreases as the surface charge is increased. This violates an alleged exact condition for such systems which has, however, recently been called into question by Attard et al. [J. Chem. Phys. 96, xxxx (1992)] and confirms their analysis that the surface potential need not be a monotone function of the surface charge.
Desempenho no treinamento auditivo computadorizado Performance in computerized auditory training Computer-based auditory training: different type of performance analysis

Purpose: Analyze and correlate the auditory performance in the evaluation stage in the chosen software and electrophysiological responses pre and post computer-based auditory training. Methods: This is a longitudinal, comparative, clinical and experimental study, performed after the approval of the ethics committee. The sample consisted of seven children, aged 7 to 8 years and 11 months, from both genders, diagnosed with auditory processing disorder. The therapeutic intervention was based on the training with the Escuta Ativa  software and composed of 12 sessions, performed twice a week, lasting approximately 30 minutes each. The score in the evaluation stage in the chosen software and the findings of the electrophysiological measurement on Long-Latency Potential Evoked Auditory, specifically P3 component, pre and post-training, were analyzed through an adequate statistical study. Results: Among the three stages of the evaluation by the software, there was no statistically significant post-training result. As for the P3 component, 3 out of the 4 children started to have it post-intervention therapy. In the search for correlation between behavioral and electrophysiological results, there was no statistical significance in either moments of the evaluation. Conclusion: It was not possible to verify a significant difference between the pre and post-training periods in the evaluation stage of the software itself, showing the need for further studies to verify the use of this evaluation tool in a clinical setting. An effect of post-training plasticity with the appearance of P3 component was noted in some children. There was no correlation between the evaluation steps by the software and the electrophysiological measurement.
Effect of Laser Fluence on the Characteristics of ZnO Nanoparticles Produced by Laser Ablation in Acetone

We have studied the effects of the laser fluence on the characteristics of ZnO nanoparticles produced by pulsed laser ablation (PLA) of Zn plate in acetone. The beam of a Q-switched Nd:YAG laser of 1064 wavelength at 7 ns pulse width and different fluencies was employed to produce nanoparticles. The ZnO nanoparticles were found to be hexagonal. The size distribution of generated nanoparticles is increased by increasing the laser fluence. The production rate of nanoparticles is increased with increasing the laser fluence. ZnO nanoparticles were formed with spherical shape. The bandgap energy of nanoparticles is calculated to be 3.59–3.89 eV. In this range of ZnO nanoparticle size, photoluminescence spectrum exhibits two peaks due to bandgap transition and defect levels.
Sexting en universitarios: relación con edad, sexo y autoestima

Sexting is a globalized social phenomenon that increases with age in adolescents, although there are few researches focused in its practice in university students, goal of the present study, which involved 899 students of the University of Granada (Spain) with ages between 18 and 24 years. The objectives were to know (through analysis of frequencies and correlations) the prevalence of sexting between men and women, to analyze the relation with age, sex and self-esteem; and to determine the prevalence of the practice of sexting by age. Two instruments were used, the Sexting Behaviors Scale and the Rosenberg Self-Esteem Scale. The relevance of the study lies in the fact that confirm that both men and women practice sexting, more men, and that the practice increases until the 21 years, falling slightly at 24. No relation was found with self-esteem. The study concludes that since most of the students have done sexting, precaution is recommended, because of the risk of the negative personal and professional consequences that may result, for the wide dissemination and permanence that can have this information in the network.
La autoestima sexual: su relación con la excitación sexual

Abstract The aim was to analyze the relationship between sexual self-esteem (SSE) and sexual arousal as a trait, as a state and as a component of the sexual response. The sample consisted of 65 heterosexual young people who completed the Sexual Excitation subscale of the Sexual Inhibition/ Sexual Excitation Scales-Short Form, the Massachusetts General Hospital Sexual Functioning Questionnaire, and the Sexual Self-esteem subscale of the Brief Sexuality Scale. Participants performed an experimental task where they completed the Ratings of Sexual Arousal and the Ratings of Genital Sensations after visualizing a neutral film and another one with explicit sexual content. The results showed significant associations between SSE and sexual arousal as a trait and as a component of the sexual response. These two types of excitation explained a significant percentage of the SSE (R2 = 0.19). However, sexual arousal as a state did not correlate to the SSE.
