Temperature Effects Compensation Strategy for Guided Wave Based Structural Health Monitoring

The work presented in this paper focuses on the dev elopment of analytical methods to compensate for th e temperature effects on guided wave propagation. The physical effects of temperature upon the registere d signals are explored experimentally over considerably large temperature range and frequency bandwidths using b oth piezoelectric sensors and laser vibrometer. The obs ervations made are mathematically interpreted and a mathematical framework which enables a new strategy for compensation of the temperature effects on Lam b waves is formulated. A0 mode propagation is simulat ed analytically using the proposed method and the r esult is compared with alternative methods and with measurem ents. The strategy is validated also in an experime ntal campaign where the plate with the installed SMART L ayer® is monitored for low temperature differences at room conditions over longer periods of time. Damage sc narios under the form of added mass were consid ered and the influence of temperature on the damage dete ction and the efficiency of the proposed strategy a re investigated.
Developing science concepts in secondary classrooms : an analysis of pedagogical interactions from a Vygotskian perspective

This study is concerned with how teachers use and guide classroom talk to support students in developing an understanding of scientific conceptual knowledge. The focus is on teachers and teaching. The study involves developing theoretical tools for describing the ways in which teachers make scientific ways of talking and knowing available to their students in classroom settings. The study has both theoretical and empirical components. The theoretical component involves drawing on aspects of Vygotslcy's socio-cultural theory of learning and development and the work of other neo-Vygotskian scholars to develop theoretical tools, based on the concept of the teaching narrative, for analysing the teaching interactions of the classroom. The empirical part involves taking those theoretical tools and applying them to real classroom situations. It is anticipated that the process of applying the theoretical tools to particular classroom situations will enable elaboration and further development of those tools; in this respect there is close interlinking between theoretical and empirical components of the study. The empirical component is based on two case studies. These case studies detail short teaching sequences in which two teachers introduce their classes to particular scientific concepts. The first case involves teaching and learning about chemical change (focussing on the process of rusting) and the second about air pressure. In summary, the main aim of this thesis is to draw upon Vygotskian theory to develop ways of talking and thinking about language-based pedagogical strategies of science teaching. The intention is that such ways of talking and thinking, framed in terms of the teaching narrative, should contribute to the professional language of science teaching providing tools for reflecting on and developing teaching practice.
The Effect of Podcast transcription Activities on Intermediate and Advanced EFL Learners’ Writing Accuracy

Abstract This study investigated the effect of podcast transcription on learners' writing accuracy of intermediate and advanced groups among Iranian EFL learners. The research was carried out in two classes, and fifty students were employed as the subjects of the study. The classes were randomly assigned to two groups who were taught via podcast transcription materials (i.e., Merlot Website). All the subjects were required to answer the writing accuracy questions for the pre-test before the treatment and took a post-test after attending writing courses. During the course of study the participants worked on writing accuracy lessons mainly grammar provided by podcast transcription materials extracted from the transcriptions of oral podcast files (i.e., extracted from www.merlot.com ) focusing in grammatical pattern in the transcribed texts. At the end of the treatment which took 10 sessions of instruction, they sat for a post-test writing accuracy achievement test. Data were collected and analyzed through descriptive and inferential statistics. Paired Samples t -test was run to compare the effect of podcast transcriptions among groups. It came to be known that advanced learners outperformed the other group in gaining higher scores in writing achievement post-test (p<.05).
Activity patterns in pike ( Esox lucius ) , as determined by motion-sensing telemetry

Activity patterns of pike fitted with motion-sensing radio tags were recorded using novel automated monitoring equipment. Activity was categorised into short duration (<5 s) and long duration (≥5 s) events. Pike displayed short duration activity events throughout the day and night. Long duration activity events were very sporadic and were often followed by long periods (>24 h) of quiescence. Experimental and observational records (based on over 8500 tracking observations) indicated that these long duration events followed by quiescent periods could be associated with the fish feeding. In total, active pulse patterns (both long and short duration) were only recorded for ~5% of the time that the fish were monitored. Analysis of the temporal patterns in the long duration activity events showed distinct diel patterns, and some seasonal variation associated with sunrise and sunset times. Results from the automated system are compared with results obtained from manual tracking. Data show that activity monitoring could be a useful method for determining the feeding periodicity of these fish and would enable a greater understanding of predator – prey interaction. 231 Spedicato, M.T. ; Lembo, G. ; Marmulla, G.

Seasonal patterns in the benthic realm of a glacial fjord (Martinez Channel, Chilean Patagonia): the role of suspended sediment and terrestrial organic matter

Complex marine−terrestrial interactions characterize Chilean fjords, where benthic communities influence the distribution of organic matter (OM). We examined spatial and seasonal changes in the hydrography, sediment conditions and soft-bottom macrobenthic, meiobenthic, and total microbial biomass in a glacial Patagonian fjord (Martinez Channel, Chile). The transport of a high load of glacial mineral and particulate OM to the fjord in the austral summer coincided with low total live benthic biomass. Multivariate analysis evidenced temporal-related macrofaunal groups influenced by the different environments produced by the advection of sediment transport and terrestrial OM from the Baker River, Chile. The relationships between density/biomass and respiration versus body size varied considerably with distance from major riverine inputs, but the slopes of density size spectra and normalized biomass size spectra were less negative in summer than in winter. Occasional large-scale advective processes in the water column affected sediment conditions and removed surface macrofauna, influencing the slope and intercept of the regression models. In the outer fjord, lateral advection and subsequent sedimentation of terrestrial OM contributed a significant fraction to total OM sediments (<14.76%). Stable carbon isotopes measured in benthic organisms suggest that benthic communities in the inner fjord may assimilate a significant fraction of terrestrial OM via heterotrophic bacteria in contrast to the minor input of terrestrial OM in the outer fjord.
The personality profi les of early adopters of energy-effi cient technology

This study investigates whether energy efficiency investments are driven by differences in personality traits among homeowners. Using data on nearly 3,000 households in Germany, we estimate that compared to the median level, homeowners in the lowest quartile of Openness to Experience have 5.0%-23.4% lower propensity to invest in capital-intensive energy efficiency measures, while homeowners in the highest quartile of Agreeableness are 7.7%-18.0% less likely to do so. Splitting the energy efficiency investments into two groups yields stronger effects of the same two personality traits for window modernisations and thermal insulation installations, whereas no impact of the personality traits is observed for solar energy and other alternative energy systems, possibly because subsidies for the latter were introduced much earlier in Germany, overriding any effects of personality traits in the investment decisions. These findings may also suggest that personality traits are of greater significance for marginal investors.
AN ANALYSIS OF GRAMMATICAL ERRORS IN USING SIMPLE PRESENT TENSE IN DESCRIPTIVE TEXT WRITING BY STUDENTS OF MAN 1 (MODEL) BANDAR LAMPUNG

Abstract: The objectives of this research were to investigate how simple present tense was used by students in descriptive text writing and to identify the common error made by students’ in using simple present tense in their descriptive text based on Surface Strategy Taxonomy. This research was designed in the form of qualitative research, especially in descriptive method. This research was conducted at MAN 1 (Model) Bandar Lampung. The subject of this research was the students of class XI.A. 1 which consisted of 33 students. In analyzing the data, the researcher collected the data from the students, determined whether simple present tense was used in well-formed or error by the students, identified the grammatical errors made by the students, classified the errors of using simple present tense in students’ descriptive text to find out the frequency of errors, displayed the data, calculated the data taken, and made the percentage in each category. The result shows that the students used more correct simple present tense than errors. The correct use of simple present tense was 73.81%, whereas the error in using simple present tense was 26.19%. Furthermore, the highest frequency of errors made by the students based on surface strategy taxonomy was omission error with 56 items (50.90%). The teachers are suggested to give much practice about the use of ending -s or –es in simple present tense in order to minimize the omission errors. Moreover, for other researchers, they can provide some techniques to increase students’ mastery of simple present tense. Key words: Grammatical Error, Simple Present Tense, Descriptive text
A positive role model may stimulate career oriented behavior.

This study examined the effects of social comparison among students in their final year of study. Participants were presented with a fictitious interview with a new graduate who was either successful or unsuccessful in the job market. Exposure to the successful target led to a higher degree of inspiration, identification, and proactive career behavior than did exposure to the unsuccessful target. The higher participants were in social comparison orientation (dispositional tendency to compare oneself with others), the more they identified with the targets and the more proactive career behavior they showed. This suggests that, overall, comparing oneself with others may inspire individuals to actively work on their careers.
Caste–Gender Intersectionalities and the Curious Case of Child Nutrition

A growing body of research has addressed the issue of intersectionality since the last three decades, mostly adopting qualitative methodologies. Quantitative attempts to capture intersectionality have been recent and few. We invoke the framework of intersectionality to shed light on the puzzle of an insignificant gender gap in child nutrition in India. Given the multifaceted intersections of caste and gender in shaping inequalities in other indicators such as childhood mortality, reported preference for sons and labour market outcomes, we examine the variations in nutritional status of children across the intersections of the two axes, sex and caste. This is a methodological paper, attempting to illustrate the various quantitative methods that have been used (with or without adhering to the term â€˜intersectionalityâ€™) or may be used to capture intersectional inequalities.
SEASONAL PRECIPITATION PREDICTION OVER SOUTH AMERICA WITH THE ETACLIM

The seasonal forecasts of precipitation and temperature on a regional scale are very useful, mainly for the regions affected by extreme events: such as droughts and floods. These events are commonly associated to global scale phenomena (e.g.: El Niño/South Oscillation). The aim of this work is to improve the performance of seasonal regional forecasts of extreme events over South America using a mixed physics ensemble approach. For this purpose, seasonal simulations using the ETA regional climate model (ETACLIM) of the Center for Weather Forecasting and Climate Studies (CPTEC) were carried out for austral summer 1997/98 (El Niño). The microphysics and convection schemes available in the model will be used to constitute the members of the ensemble. The preliminary results using the convective schemes (Betts-Miller-Janjic, Kain-Fritsch and RAS) showed encouraging perspectives for climate predictions over South America region.

RELATIONSHIP BETWEEN BIOCHEMICAL ENERGY RESERVES AND SOME ECOLOGICAL TRAITS OF THREE SPECIES OF ENTOMOPATHOGENIC NEMATODES

The biochemical energy reserves of three species of entomopathogenic nematodes (EPN) were analysed quantitatively at three infective juvenile ages 0, 20 and 90 days for Steinernema (Steinernema riobrave) , less than 7, 30 and 50 days and 0, 20 and 40 days for Heterorhabditis (Heterorhabditis bacteriophora and Heterorhabditis indica) respectively. Lipid, protein, carbohydrates and glycogen contents of the two species of Heterorhabditis and one species of Steinernema were determined. Results revealed that total lipids are the main component, comprising approximately 42.55 of nematode dry weight for S. riobrave and 50.52%, 53.75% for H. bacteriophora and H. indica, respectively, when freshly emerged from their hosts. These percentages declined significantly at the other two juvenile ages of the three species. Glycogen and protein contents in all species exhibited minor changes during the tested juvenile ages. Estimation of total carbohydrates appeared to be source of energy that only utilized early in the ambushing state of S. riobrave and when juveniles get older in H. indica and H. bacteriophora. Infectivity of the three nematode species at the three tested ages was not affected, where approximately 100% Galleria mellonella mortality was recorded except a slight insignificant decrease (97.33%) in H. indica at the age of 40 days. Penetration rate of H. indica, and H. bacteriophora decreased with the declining of the total lipid content at the three juvenile ages, while the penetration rate in S. riobravae exhibited significant decrease only at 90-day old juveniles. Significant decreases in migration rate were evident in H. indica and H. bacteriophora as the total lipid content declined in the juvenile ages. These results might be helpful in increasing the efficiency of EPN as biological control agents against insect pests by improving shelf-life of nematode juveniles and establishing a simple and easy quality control method for different nematode species or strains.
Study of Common Bacterial Pathogen Causing Urinary Tract Infection in Assam Medical College and Hospital, India

Urinary tract infection (UTI) is one of the most common infections encountered by clinicians and approximately 1 in 3 women will be subjected to antimicrobial treatment for urinary tract infection before age 25. UTI is most predominant in female than in male. Area-specific monitoring studies aimed to gain knowledge about the type of pathogens responsible for urinary tract infections and their resistance patterns may help the clinician to choose the correct empirical treatment. Therefore, the aim of this study is to determine the type and antibiotic resistance pattern of the urinary pathogens isolated from patients attending Assam Medical College and Hospital in Dibrugarh, Assam, India, from November 2013 to January 2014. In the present study, samples were collected from 40 patients showing various clinical symptoms were suspected to UTI. Clean-Catch midstream urine of the patients was collected. Urine samples were cultured for isolation of the microbial agents of UTI. The isolated bacteria were identified using biochemical tests. Disk diffusion susceptibility test was used to determine susceptibility of bacterial agents to antibiotics. Retrospective analysis was carried out for 40 urine samples, 55% UTI was found in case of female and 45% in case of male and also 35% UTI was found in age group 1-15. Escherichia coli were the most common cause of UTI. Isolated and diagnosed bacteria were Escherichia coli (45%), Pseudomonas (25%), Staphylococcus (15%), and Klebsiella (15%). These uropathogens showed different pattern of antimicrobial drug susceptibility against Amikacin, Cefotaxime, Ciprofloxacin, Kanamycin, Tetracycline and Ampicillin. Almost all organisms are sensitive to Amikacin than other antibiotics.
Strengthening and Repair of Reinforced Concrete Columns by Jacketing: State-of-the-Art Review

Sustainability necessitates the protection of infrastructure from any kind of deterioration over the life cycle of the asset. Deterioration in the capacity of reinforced concrete (RC) infrastructure (e.g., bridges, buildings, etc.) may result from localised damage sustained during extreme loading scenarios, such as earthquakes, hurricanes or tsunamis. In addition, factors such as the corrosion of rebars or ageing may also deteriorate or degrade the capacity of an RC column, thereby necessitating immediate strengthening to either extend or ensure its design life is not limited. The aim of this paper is to provide a state-of-the-art review of various strengthening and repair methods for RC columns proposed by different researchers in the last two decades. The scope of this review paper is limited to jacketing techniques for strengthening and/or repairing both normal- and high-strength RC columns. The paper also identifies potential research gaps and outlines the future direction of research into the strengthening and repair of RC columns.

This study investigates the relationship between exports, foreign direct investments (FDI) and economic growth in five Eurozone countries (Greece, Portugal, Ireland, Spain, and Italy) using panel data for the period 1970 to 2011. The panel data causality results revealed that there is bidirectional causality between exports and economic development, while there is no causality between economic growth and FDI nor between FDI and exports.
Hsp 90 inhibitor SNX-2112 inhibits cell growth by regulating Bcl-2 family proteins and cyclin proteins in MCF-7 cells

Breast cancer has been a major threat for human health. Tens of Millions of people are die of breast cancer in annual year. Breast cancer has been being one of the most important malignancies, and it is also the second most responsible for cancer mortality all the word, especially among femal cancer patients. Heat shock protein 90 (Hsp90) is highly expressed in tumor cells, and is an ATP-dependent molecular chaperone that can interrelate and interact with numerous proteins. Hsp90 can play a crucial role in numerous cell signaling pathway which are involved in cell proliferation and survival, cell metabolism. SNX-2112, a novel and selective Hsp90 inhibitor, exhibits a favourable anticancer activity. SNX-2112 can effectively inhibit cell growth in diversified cancers, including breast cancer. However, little is known about its mechanism of action in breast cancer and needs to be further elaborated. In this study, we investigated the effects of SNX-2112 in MCF-7 cells. SNX-2112 inhibited cell growth via mediating expression levels of mitochondrial proteins, downregulated Bcl-2 and Bcl-xl, upregulated Bim. Further study suggested that SNX-2112 also regulated cyclin proteins in breast cancer MCF-7 cells, and may be a promosing targeted therapy drug.
PRINCIPALS ’ LEADERSHIP STYLES : A KOUZES AND POSNER MODEL BASED ASSESSMENT OF PRINCIPALS ’ LEADERSHIP PRACTICES

The purpose of this study was to determine principals’ leadership practices in secondary schools using Kouzes and Posner Leadership Practices Inventory (LPI) in view of the enormous impact global changes and the consequent reforms and restructuring going on in education is having on principals’ leadership behaviours. Population of the study was all the 21 principals and 281 teachers in Aguata Local Government Area of Anambra State. Guided by two research questions and one null hypothesis, a 30-item Kouzes and Posner LPI, which examines the leadership practices in five areas based on a 10-point scale, was used for the study as a tool for measuring perceptions of leadership practices. Although the validity and reliability of the instrument have been established by Kouzes and Posner (2002a), the researcher repeated it to ensure psychometric properties of the questionnaire in Anambra State situation and culture. The internal consistency measures of reliability were computed for the instrument using Cronbach Coefficient Alpha. As a result, the internal consistency rating for the five sub-scales were . 78 . 88. Therefore, the researcher assumed the instrument to be reliable for the present study. Data was analyzed using Means, Standard Deviation, and t-tests. Findings showed that while principals self-reported that they more frequently use their leadership behaviours, teachers observed that they are less regular in the use of the leadership behaviours as measured by Kouzes and Posner LPI. However, it was recommended among others that workshops should be conducted for the principals to train them practically on effective leadership practices, especially as postulated by Kouzes and Posner.
An Emotional BCI during Listening to Quran By Mashail Laffai Alsolamy

Brain Computer Interface (BCI) allows users to interact with external devices using their brainwave signals. On the other hand, emotions play an important role in our daily life and affect our decisions. To understanding better the behavior of the human being, his/her emotion should be estimated. Different methods were proposed to estimate the subject’s emotion. Most of these methods are based on subject’s voice, face and body gestures which are not reliable because people can conceal their feelings. To overcome this problem, this work proposed a system to estimate the subject’s emotion from his/her brainwaves that are reliable and enable us to know the inner emotions. To this end, an experiment was designed to make the user listening to Quran verses while the brainwaves are recorded and analyzed to estimate the subject’s emotion. The proposed model was applied and tested to 14 participants. The obtained results show that the proposed model correctly estimates the participant’s emotions by accuracy 89.04%. More experiments are needed to evaluate the performance of the proposed model in real time.
