Published: July 2013

OBJECTIVE: to identify factors which constrain or determine the return to sexual activity in the puerperium. METHOD: exploratory and descriptive study undertaken in a university hospital in the South of Brazil. Fifteen women who had recently given birth, who received a consultation with the nurse in the period August - October 2011, took part in the study. Data was collected after the consultation had finished through semi-structured interviews, in which the women who had recently given birth were asked about the return to sexual activity and the feelings involved in this process. RESULTS: the principal determinant/constraint for return to sexual activity in the post-natal period was the fear of a new pregnancy. Fear of feeling pain, permission from the health professional, shame of their own bodies and changes in libido emerged as constraining and/or determinant factors in the thematic analysis. CONCLUSION: it is considered fundamental for the issue of contraception to be addressed with the woman/couple during the pre-natal consultation, so that there may be opportunities for reflection and dialog prior to the critical time itself.

Snow load damage to buildings: physical and economic impacts
Authors: Strobel Kristen , Liel Abbie
Published: July 2013

This study examines the physical and economic impacts of snow-related building failures occurring in the USA between autumn 2008 and spring 2011. The study employed a web-based survey distributed to owners and operators of 332 buildings. These buildings were identified in newspaper archives or online news sources as having been damaged by snow loads. This paper describes the 40 responses received. Damage to these buildings ranged from minor to complete collapse; survey responses showed that the roof structure and non-structural roofing and ceiling materials were particularly impacted. Certain structural types (especially timber roofed) and older buildings tended to experience higher levels of damage. On average, the buildings incurred US$ 166 per gross m2 of costs associated with repairing or rebuilding, damaged US$ 25 per gross m2 of property and building contents, and interrupted business or other operations for 122 days. Collection of these data represents a first step towards the development of loss estimation models needed for a comprehensive performance-based engineering framework for the design and assessment of buildings under snow loads.
Investigation of water ingress to concrete basements
Authors: Barnes Richard Andrew
Published: July 2013

In design terms, basements are water-excluding structures and there is a wealth of information available to aid the designer. Despite the comprehensive guidance available, there are still numerous instances of water ingress to concrete basements. One guide suggests that half of all basements leak at some time during their construction and that a significant proportion leak post-construction. By examining a number of case studies, the aim of this paper is to illustrate the reasons for such water ingress and possibly suggest how it can be avoided in the future. The case studies are divided into three topics – workmanship, unexpected events and cracking. There are many reasons why water ingress to concrete basements occurs, including poor workmanship and changing groundwater conditions. Most importantly, it needs to be accepted that reinforced concrete can, and in most cases will, crack and that water can make its way through these cracks. Water-resisting admixtures can prevent water seeping through the concrete material but not from passing through cracks that form in concrete.
Discrete-element method simulation of a model test of an embankment reinforced with horizontal–vertical inclusions

Published: July 2013

ABSTRACT: A series of laboratory model tests were conducted on unreinforced embankments, embankments reinforced with two-layer horizontal inclusions, and embankments reinforced with two-layer horizontal–vertical (H–V) inclusions. It is found that H–V inclusions perform better than horizontal inclusions in improving the bearing capacity and restricting the lateral displacements. In the light of the model test results, numerical simulations were performed, using the discrete-element method (DEM), to study the behavior of soil embankments reinforced with H–V inclusions. The effects of vertical inclusions on the distribution of contact forces and soil deformations were investigated. It is shown that when an embankment is reinforced with H–V inclusions, multiple vertical force-bearing columns develop inside it that redistribute the stresses and improve the bearing capacity. With the application of two-layer H–V inclusions, the failure surface is separated and the arcs become discontinuous. The horizontal reinforcing elements experience mainly tensile forces, and the vertical reinforcing elements provide resistance to soil particles. Compared with conventional horizontal inclusions, H–V inclusions restrict the movements of soil particles more effectively; consequently, the displacements of soil particles in both the horizontal and vertical directions are smaller. Overall, the DEM model can simulate the model tests accurately, and is helpful for analysis of the microscopic behavior of reinforced soil.
Behaviour of soft ground improved by conventional and geogrid-encased stone columns, based on FEM study
Authors: Elsawy M.B.D.
Published: July 2013

ABSTRACT: Construction of embankments on soft natural soil may be a challenge, owing to its low shear strength and high compressibility. Stone columns, which depend on lateral support from the soft ground, have been utilised to accelerate foundation consolidation, and to increase foundation bearing capacity. To keep the drainage function, and to improve the stone columns as reinforcing elements, geosynthetics are used for column encasement. In this research, the behaviour of full-scale unreinforced and reinforced Bremerhaven clay with conventional and geogrid-encased stone columns under embankment loads is analysed numerically. The consolidation analysis is applied to investigate the long-term behaviour of the clay. The results show that the stone columns in the Bremerhaven clay increase the bearing capacity and accelerate the reduction of excess pore water pressure of the foundation. Once the stone columns are encased, more improvement occurs in their performance in soft soil. The analyses also indicate that stress concentration generation in the stone columns contributes significantly to the acceleration of soil consolidation.

Authors: Vinogradov Dmitriy , Polyakov Aleksey , Kuntsevich Aleksey
Published: July 2013

The influence of the level of mineral nutrition and rate of seed sowing on
yield and fatty acid composition of linseed (Linum usitatissimum L.) in the
Non-chernozem zone of Russia was studied. It was shown that the level of
mineral fertilizers N - 90, P2O5 - 60, and K2O - 60 kg/ha under the rate of
sowing of 8 million seeds/ha provided maximum seed yield of 1.94 t/ha. A
clear correlation between oil content and rate of sowing has not been
established. Under an increasing level of mineral nutrition, oil content was
slightly increased. The composition of oil was slightly changed under the
influence of the studied factors.
Overnutrition Stimulates Intestinal Epithelium Proliferation Through β-Catenin Signaling in Obese Mice

Published: July 2013

Obesity is a major risk factor for type 2 diabetes and cardiovascular diseases. And overnutrition is a leading cause of obesity. After most nutrients are ingested, they are absorbed in the small intestine. Signals from β-catenin are essential to maintain development of the small intestine and homeostasis. In this study, we used a hyperphagia db/db obese mouse model and a high-fat diet (HFD)-induced obesity mouse model to investigate the effects of overnutrition on intestinal function and β-catenin signaling. The β-catenin protein was upregulated along with inactivation of glycogen synthase kinase (GSK)-3β in the intestines of both db/db and HFD mice. Proliferation of intestinal epithelial stem cells, villi length, nutrient absorption, and body weight also increased in both models. These changes were reversed by caloric restriction in db/db mice and by β-catenin inhibitor JW55 (a small molecule that increases β-catenin degradation) in HFD mice. Parallel, in vitro experiments showed that β-catenin accumulation and cell proliferation stimulated by glucose were blocked by the β-catenin inhibitor FH535. And the GSK-3 inhibitor CHIR98014 in an intestinal epithelial cell line increased β-catenin accumulation and cyclin D1 expression. These results suggested that, besides contribution to intestinal development and homeostasis, GSK-3β/β-catenin signaling plays a central role in intestinal morphological and functional changes in response to overnutrition. Manipulating the GSK-3β/β-catenin signaling pathway in intestinal epithelium might become a therapeutic intervention for obesity induced by overnutrition.

Published: July 2013

The goal was to explore the effect of a moderate-intensity exercise on egocentric distance estimates (the distance between the participant and an object in space) in physically trained and untrained participants ( N = 54), divided into three groups of 18 national-level soccer players, 18 sedentary people, and 18 controls. Participants engaged in a distance estimation task at rest, and also while pedalling on an ergocycle for 10 min. at 60% of the maximal aerobic intensity. Estimates were recorded during pre-exercise, stability Phase 1 (between the 1st and the 2nd min. of exercise), Phase 2 (5th to 6th min.), Phase 3, (9th to 10th min.), and immediately after the exercise. Estimates of egocentric distance were more accurate in trained than untrained participants. Perception improved during and after the exercise in comparison with pre-exercise. In addition, the group x exercise interaction indicated estimation improved during and after exercise, with more accuracy in the trained than untrained participants. Fitness and moderate aerobic exercise improve the egocentric distance estimation in humans.

Published: July 2013

Some people with cerebral palsy have motor and associated impairments that may hinder verbal and gestural expression to various extents. This study explores whether the ability to produce verbal or gestural expressions may be related to the comprehension of verbal communications and gestures. The influence of severity of motor impairment, general cognitive performance, and age on comprehension ability was also explored. Forty people with cerebral palsy were assigned to different groups according to their verbal and gestural expression abilities. A neuropsychological assessment of comprehension abilities and general cognitive performance was carried out. Multiple linear regression analysis was applied to identify the possible influence of expression abilities on comprehension abilities and also to detect the possible contribution of severity of motor impairment, general cognitive performance, and age. Results indicate that verbal and gestural comprehension was mainly predicted by general cognitive performance. Severity of motor impairment and age did not contribute to predicting comprehension abilities. Only verbal grammar comprehension was significantly predicted by verbal expression ability. Verbal expression ability may be an important marker for cerebral palsy therapies. In non-ambulant patients with bilateral cerebral palsy, impaired gestural expression should not be taken as an indicator of impaired gestural comprehension.

Published: July 2013

A group of 59 obese children ages 6–12 years were interviewed for current medical diagnoses (e.g., Attention Deficit Hyperactivity Disorder- ADHD, and clumsiness) and later were examined posturographically for balance and stability. General stability of all the obese children deviated significantly from norms. 32.2% of the obese children had a pattern of balance that could indicate orthopedic problems. Obese children with ADHD or perceived clumsiness had significantly worse balance and postural performance compared to other obese children. Balance and posture among obese children without suspicion of problems were similar to non-obese controls. In conclusion, obese children with associated disorders (such as ADHD and perceived clumsiness) manifested disturbance in balance control. Thus, physical activity interventions for these children should include safety measures to decrease the chances of falling and subsequent injury.
Effects of a Short-Term Coordination Exercise Program during School Recess: Agility of Seven- to Eight-Year-Old Elementary School Children
Authors: Yasumitsu Tatsuo , Nogawa Haruo
Published: July 2013

This study tested the effect of a short-term coordination program focused on improving the agility of school children ages 7 to 8 years. Healthy Japanese children were placed in an experimental group of 26 children (10 girls, 16 boys) and a control group of 20 children (9 girls, 11 boys). The experimental group participated in 10 coordination program sessions during recesses; each session was performed 1 to 3 times per week, for 26 days. No differences were observed between the groups in repeated side-step scores prior to the program, although an interaction was observed after the completion of the treatment. The short-term coordination program was effective in increasing the agility of elementary school children aged 7 to 8 years.

Published: July 2013

General participation in contests such as ultra-marathons and ultra-triathlons has increased considerably over the past 30 years, especially among women. This study investigated performance trends in the Swiss Bike Masters, one of the first and most prestigious mountain bike, ultra-endurance races in its class, with comparisons of participation and performance trends to similar races. The development of performance in the Swiss Bike Masters held between 1994 and 2012 was investigated by analysing the number of finishers, their age, sex, and cycling speed. Between 1994 and 2009, the athletes had to cover 120 kilometers with a total difference in altitude of 5,000 meters. Since 2010, the race distance was shortened to 105 kilometers and the total difference in altitude was reduced to 4,400 meters. The total men participating and total finishing decreased significantly, while women's participation has remained low. The age of the annual winners and the annual top three finishers showed no changes over time. Performances of the annual fastest women improved, while performances of the annual fastest men remained unchanged. To summarize, rate of finishing has decreased for men and has been stable, but low, among women. The sex difference in cycling speed for the best cyclists has decreased across the years.
Oscillative surface morphology in peritectic NiAl using phase-field modeling
Authors: Kist Marius , Choudhury Abhik , Nestler Britta
Published: July 2013

The NiAl-γ–γ′-system is numerically modeled using a multi-phase-field approach near its peritectic. The free energies are approximated as second order polynomials of the concentration. The parameters of these functions are fitted using experimentally determined values for the peritectic equilibrium concentrations and the liquidus/solidus slopes at the peritectic temperature. A study on lateral growth of a peritectic phase (γ') layer on a primary (γ) substrate reveals an oscillation of the layer interfaces at very low undercoolings (0.08 K). This morphology has its seeds in an oscillatory rotation of the triple junction. A mechanism for the origin of rotation is described and a reason for its disappearance at higher undercoolings is discussed. While the γ–γ′ surface energy as well as the γ interdiffusion constant are unknown, the influence of these parameters on the oscillation morphology is investigated.
A one-pot synthesis of Ag/α-Fe2O3 nanoplates with gelatin and their photocatalytic activity
Authors: Zhang Danhui , Yang Houbo
Published: July 2013

Ag/α-Fe2O3 nanoplates with a size range of 40–60 nm were fabricated by means of a facile gelatin assisted hydrothermal technique. The samples were characterized using X-ray diffraction, transmission electron microscopy, and UV-vis spectroscopy. The results demonstrate that these composites consist of silver and hematite (α-Fe2O3) and the band gap of the Ag/α-Fe2O3 composite is much narrower than for the pure α-Fe2O3. Furthermore, the photocatalysis test shows that the Ag/α-Fe2O3 composite exhibits a higher photocatalytic activity than the pure α-Fe2O3 nanoplates, thereby implying that the Ag/α-Fe2O3 interfaces promote the separation of photogenerated electron–hole pairs and enhance the photocatalytic activity.
Research on the creep fracture mechanism of FGH95 Ni-based superalloy
Authors: Jun Xie , Sugui Tian , Xiaoming Zhou , Yong Su , Jiao Liu
Published: July 2013

The creep fracture mechanism of FGH95 superalloy has been investigated by means of microstructure observation and creep behaviour measurement. Results show that, after solution treatment at 1150°C, the coarser γ′ precipitates distribute in the wider regions of previous particle boundaries. As the solution temperature increases to 1165°C, the grains grow in the alloy and carbide films precipitate along the grain boundaries. When the alloy is solution treated at 1160°C, the coarser γ′ phase in boundary regions is fully dissolved, and granular carbides precipitate along the grain boundaries, which may effectively restrain boundary sliding and hinder dislocation movements to improve the creep resistance of the alloy. During creep, the deformation feature of the alloy is that slipping dislocations with single or double orientations and stacking faults are activated in the alloy. As creep progresses, the amount of slip traces increases to bring about stress concentration and cause microcracks to be initiated and propagated along the grain boundaries up to the rupture of the alloy.

Published: July 2013

Background: Silent cerebral infarction (SCI) detected incidentally by MRI is considered the preliminary stage of accidental stroke and assumed to be secondary to atherosclerotic vascular disease (ASVD).The Duplex Color Doppler study is the initial screening non-invasive modality to identify carotid atherosclerotic changes and is the best approach for preoperative carotid artery evaluation in asymptomatic patients who can be expected to benefit of reduced risk of stroke in future. This cross- sectional study was carried out to assess the diagnostic usefulness of Duplex Color Doppler sonography in the evaluation of asymptomatic carotid atherosclerosis in prediction of silent cerebral infarction. Nature of extracranial carotid plaque and degree of luminal stenosis were compared & associated with MRI findings and risk factors of silent cerebral infarction. Method: This cross sectional study was carried out in the Radiology & Imaging Department of Dhaka Medical College Hospital during the period of July 2009 to June 2011 on 70 adult subjects of both sexes aged >50 years. Clinically suspected patients of silent cerebral infarction referred to Radiology & Imaging department of DMCH from OPD and Indoor Patient department underwent MRI of brain and among them those diagnosed as having Lacunar infarcts (Silent Cerebral Infarction) underwent Extra-cranial Carotid Duplex Color Doppler examination on both sides. Carotid lesions were evaluated by plaque score, maximum percent stenosis and the existence of ulcerated lesions. The relations between the carotid lesions and the incidence, size or localization of the brain lesions were investigated. Results: The incidence of SCI increases with age & more prevalent in male (P<0.05).Most SCI lesions were <1cm in size, single in number and is more prevalent in basal ganglia region (P<0.05) than subcortical white matter of right cerebral hemisphere (P<0.05) associated with ipsilateral high grade carotid stenosis & ulcerated plaque. The percentage of subjects with infarcts increased significantly as the plaque score increased (P<0.001) or subjects had high grade stenosis (P<0.001). The presence of pre-existing risk factors like HTN, DM, IHD, and Dyslipidaemia showed significant correlation with plaque score and SCI of brain. Conclusion: Both the severity and characteristics of asymptomatic carotid lesions estimated by Duplex color Doppler study were closely related to the appearance of silent infarcts.These results demonstrate that noninvasive assessment of carotid lesions can be useful in predicting the existence of silent cerebral infarction even in patients free from neurological deficits.

Determination of Radical Scavenging Activity and Total Phenols of Wine and Spices: A Randomized Study
Authors: Lugemwa Fulgentius , Snyder Amanda , Shaikh Koonj
Published: July 2013

Thirty eight bottles of red wine (Carbanet Sauvignon) were randomly selected based on vintage, region, price, and age (number of months in a barrel). The total phenolic content of each wine was determined using Folin-Ciocalteau assay. The radical scavenging activity was evaluated using 2,2-diphenyl-1-picryhydrazyl (DPPH) assay. Apart from a few bottles that exhibited above average radical scavenging activity and phenolic content, there was no good correlation of those two quantities with region, price or vintage. The average phenolic amount was 2874 mg/L. The lowest phenolic content was found to be 1648 mg/L for an eight dollar wine. Wine with the highest amount of phenol of 4495 mg/L was a 2007, nine dollar bottle from South America. High amount of phenols did not translate into high radical scavenging activity. Barrel-aging did not increase the amount of phenols or the radical scavenging activity of wine. In order to discover new and potent sources of antioxidants from plants, the following spices were studied: ginger, cilantro, cumin, anise, linden, eucalyptus, marjoram, oregano, sage, thyme and rosemary. Whole spices were crushed and extracted for 96 h at room temperature using a combination of ethyl acetate, ethyl alcohol and water in the ratio of 4.5:4.5:1 (v/v/v). The radical scavenging activity of extracts was evaluated using 2,2-diphenyl-1-picryhydrazyl (DPPH) assay. The total phenolic content of each spice was also determined using the Folin-Ciocalteau assay. Eucalyptus was found to be the most potent antioxidant with an LC50 of 324.1 mg of phenol/L, followed by marjoram with an LC50 of 407.5 mg of phenol/L, and rosemary with an LC50 of 414.0 mg/L. The least potent antioxidants were ginger and cilantro with LC50 of 7604 mg/L of phenol and 7876 mg of phenol/L, respectively.
A Literature Review on Heating of Ventilation Air with Large Diameter Earth Tubes in Cold Climates
Authors: Tan Lili , Love James
Published: July 2013

Earth-air heat exchange (EAHE) systems offer the possibility of reducing use of nonrenewable energy for heating ventilation air in cold climates. The number of installations of large diameter (greater than 900 mm) EAHE systems reported for cold climates is small. Even less has been reported on their heating performance, but the available information suggests that further rigorous assessment is warranted to determine whether the reported better than expected temperature rise is supported and, if so, the reasons for this. Another concern is the possibility of long-term heat depletion in the surrounding soil, which would affect performance. Only a couple of short-term experimental studies of ground temperature effects of heating with EAHE were found for cool climates. Four articles that addressed ground temperature effects with horizontal ground source heat pump exchangers had conflicting findings regarding heat depletion in the soil.
Abnormal Base Excision Repair at Trinucleotide Repeats Associated with Diseases: A Tissue-Selective Mechanism
Authors: Goula Agathi-Vasiliki , Merienne Karine
Published: July 2013

More than fifteen genetic diseases, including Huntington’s disease, myotonic dystrophy 1, fragile X syndrome and Friedreich ataxia, are caused by the aberrant expansion of a trinucleotide repeat. The mutation is unstable and further expands in specific cells or tissues with time, which can accelerate disease progression. DNA damage and base excision repair (BER) are involved in repeat instability and might contribute to the tissue selectivity of the process. In this review, we will discuss the mechanisms of trinucleotide repeat instability, focusing more specifically on the role of BER.

Published: July 2013

There is an increasing demand for organic semiconducting materials with the emergence of organic electronic devices. In particular, large-area devices such as organic thin-film photovoltaics will require significant quantities of materials for device optimization, lifetime testing and commercialization. Sourcing large quantities of materials required for the optimization of large area devices is costly and often impossible to achieve. Continuous-flow synthesis enables straight-forward scale-up of materials compared to conventional batch reactions. In this study, poly(3-hexylthiophene), P3HT, was synthesized in a bench-top continuous-flow reactor. Precise control of the molecular weight was demonstrated for the first time in flow for conjugated polymers by accurate addition of catalyst to the monomer solution. The P3HT samples synthesized in flow showed comparable performance to commercial P3HT samples in bulk heterojunction solar cell devices.
La possession de Loudun (1632-1637)
Authors: Houdard Sophie
Published: July 2013

Les écrits de la possession en France au xvii e  siècle ont souvent été travaillés par les historiens spécialistes des religions et de l’irréligion. Cet article se propose de voir en quoi l’apport de l’anthropologie, rarement mise à contribution dans le cas de la possession européenne de l’époque moderne, offrirait de nouveaux éclairages sur la possession de Loudun (1632-1637). Ce sont surtout les notions de « performance » et de « drame social », empruntées à Richard Schechner et Victor Turner, qui seront ici mises en usage. Nous verrons de quelle manière elles peuvent ouvrir de nouvelles pistes d’étude et de nouveaux points de vue sur la possédée, considérée alors comme actrice du processus social de la possession.
Body Art : la blessure comme œuvre chez Gina Pane
Authors: Le Breton David
Published: July 2013

Sur la scène artistique contemporaine, les performances se donnent à voir sous la forme d’un événement et non d’une contemplation, la matière première en est l’engagement dans l’action d’un artiste proposant une dramaturgie que les témoins découvrent au fur et à mesure de son développement. L’artiste n’est plus à l’abri dans son atelier et dans la solitude de la création mais soumis au risque d’une entreprise accomplie sous les yeux d’un public. L’œuvre de l’artiste Gina Pane sera longuement analysée comme un art en forme d’engagement où le corps est directement sollicité à travers la blessure délibérée.
Le Web des troubles alimentaires. Un nouvel art de jeûner ?
Authors: Casilli Antonio
Published: July 2013

Le phénomène contemporain des sites web « pro-ana » (ou, plus exactement, « ana-mia »), consacrés aux échanges autour des troubles des conduites alimentaires et tout particulièrement de l’anorexie mentale, réinterroge les catégories de corps, de présence et de performativité. Via leurs textes, vidéos, images, les contributeurs de ces blogs et forums documentent leurs gestes quotidiens, leurs sensibilités esthétiques. Face à la stigmatisation par l’opinion publique, leurs postures se radicalisent, se chargent de colorations héroïques, et ne se laissent plus exprimer que par un vocabulaire de citoyenneté : « choix », « liberté », « droit » d’être anorexique. Le rapport du performeur en ligne à son public s’avère principalement régi par une intention politique de recherche d’entraide et d’autonomie. L’art de jeûner, dessiné par Kafka dans le récit « Ein Hungerkünstler », se transforme alors dans un effort collectif de vigilance et de négociation autour des limites de la performativité du corps dans les environnements numériques, et dans le contexte élargi de la vie publique.
L'« événement-spectacle »
Authors: Spielmann Guy
Published: July 2013

Depuis les années 1950 s’est développé dans les pays anglophones un vaste champ de recherche et d’enseignement autour de la notion de « performance ». Bien que la masse imposante de travaux publiés depuis un demi-siècle, encore très partiellement diffusée hors de l’aire culturelle anglo-américaine, puisse induire à croire que le domaine est aujourd’hui parfaitement balisé, il lui manque encore un objet scientifique bien défini, la performance étant envisagée de manières extrêmement diverses par les théoriciens, qui s’accommodent des divergences au nom de la pluralité. Or, en termes pratiques, la performance ne trouve sa raison d’être qu’en complémentarité avec la spectation, lorsque l’une et l’autre se produisent en un lieu et à un moment donnés. C’est donc cette instance particulière, l’« événement-spectacle », qui apparaît désormais comme le légitime objet scientifique d’un champ de recherche qui dépasse les apories propres aux « études théâtrales » et aux Performance Studies .
La Turquie : une future puissance économique mondiale ?
Authors: Vérez Jean-Claude
Published: July 2013

La Turquie est considérée comme une économie émergente. Membre des BRIC ou des MIST, elle compte en 2013 en tant que puissance économique classée dans les 20 premières puissances mondiales. Depuis l’avènement de la République, l’interventionnisme a laissé place à davantage de libéralisme. La crise de 2001 puis l’arrivée de l’AKP au pouvoir en 2002 ont modifié la structure productive du pays et les réformes engagées avant 2002 ont porté leurs fruits. La croissance économique retrouvée et régulière a permis de combler certains retards et de projeter la Turquie vers d’autres horizons, au moment où les négociations avec l’UE sont au point mort. Désormais, la Turquie veut intégrer le classement des 10 premières puissances à un horizon de moyen terme et devenir une puissance régionale. Ce n’est pas impossible mais ce n’est pas acquis non plus tant il reste des défis à surmonter.

Published: July 2013

This work proposes a new algorithm to enhance the performance of the speaker verification over the communication systems based Multiple-Input Multiple-Output (MIMO) - Orthogonal Frequency Division Multiplexing (OFDM) techniques. The algorithm mainly tackles and overcomes the effect of the high Peak-to-Average Power Ratio problem that is found in OFDM systems, MIMO-OFDM combination has been developed to meet the rapidly increment in the users demand such as the ubiquitous transmission, imposing new multimedia applications and wireless services. In this algorithm, wavelets techniques have been used to denoise the affected OFDM symbol by high PAPR values. After that and based on adaptive threshold method the local maxima and minima will be determined and replaced by the average of them and their surrounding neighbors; Denoise OFDM and Replace PAPR (DORP).

A system performance investigation process will be accomplished based on both of numerical method and MATLAB simulation. Moreover, a comparison has been made to check the validity of our proposition either with our previously published work or with the literature. Although, the achieved results show that the proposed work has lower PAPR values; an additional complexity has been added to transceiverâ??s structure. Moreover, and as a result to the comparison with the conventional systems, the bit error rate (BER) performance has been improved for the same bandwidth occupancy.

As a validity process a comparison has been made with the current values found in the literature and we have achieved around 30% PAPR extra reduction. That is in addition to around 90% verification rate and noise immunity.
A Mobile Shared Workspace Supporting Healthcare Task Cooperative Planning
Authors: Lezzar Fouzi
Published: July 2013

In a health care environment, in which task planning process is fundamentally a collaborative task that requires the participation of many health care professionals with different skills working simultaneously on same cases. However, most recent healthcare research has focused on methods mainly based on communication, rather than collaboration supports. We followed then a CSCW-based planning approach which constitutes an evolution of planning environments toward new shared workspaces supporting collaboration. Our work led us first, to analyse the related tasks in an Algerian maternity ward in order to highlight the vital collaborative medical tasks that need to be modelled. The following sections outline basic design concepts of our mobile collaborative planning system, which is designed to provide a flexible group interaction support for care coordination and continuity.

Student engagement, and in particular intellectual engagement, has been identified as a key factor in learning at the high school level. While this type of engagement has an impact on student learning in fields related to science, technology, engineering and mathematics (STEM), it also has a positive impact on the learning of other disciplines such as English, Fine Arts, and Social Sciences. This report describes a set of projects co-designed by teachers and education specialists aimed at engaging students intellectually in each major high school subject area. Student use of mobile technologies, in this case the iPad2, features prominently in each of these projects. Interviews with teachers and students were conducted in order to identify evidence of intellectual engagement, as well as studentsâ?? interactions with the mobile device. Data from a survey was also used to identify the level of engagement of students involved in these projects.

Within laboratories in Engineering Education students have the chance to do own experiments and by that gain own experiences in their learning processes â?? means that they are an adequate opportunity to implement experiential and research based learning. Recently finished research projects - e.g. like the PeTEX project done by universities in Dortmund (Germany), Palermo (Italy) and Stockholm (Sweden) â?? implemented an opportunity to do experiential learning by using real laboratory equipment without being physically in the laboratory but having access via the internet. A question in this context is, how students can document their learning process and show to others (teachers and/or other students), what they have been doing. Making the whole environment available for mobile devices so that students have access from virtually everywhere and every time is the consequent further development. With this work in progress paper we show what kind of role e-portfolios can play in the learning process and which kind of scenarios are possible using the software on mobile devices. Furthermore, we show that the combination of experiential learning and the use of e-portfolios offer a great potential to promote the learnersâ?? creativity. This unique combination of topics is realized within one subtask of the project â??ELLI â?? Excellent Teaching and Learning in Engineering Educationâ? at TU Dortmund University.
Evolution of End User Participation in IT Projects
Authors: Sikorski Marcin
Published: July 2013

This chapter is aimed at presenting a review of evolutionary design paradigms, which determine the end user’s role in IT (Information Technology) projects across recent decades. This review covers different perspectives starting from technology-oriented sequential software development lifecycles, through user-centred approaches, ending finally in contemporary service design approaches supported by e-business and social media. Finally, the chapter discusses the need for “soft skills” required from the designers who wish to apply the service-relevant perspective to their IT projects. Conclusions cover novelty aspects of the designer-user interaction in service-relevant design paradigms and the impact of new design paradigms on human creativity and innovation.
Enabling IT Innovation through Soft Systems Engineering
Authors: Simonette Marcel Jacques , Spina Edison
Published: July 2013

In any Software Development process, and especially in innovation processes, the team responsible for software implementation needs to acquire the necessary knowledge to implement the project and to sustain innovation. However, the implementation team does not always convert innovative ideas into the expected value. The Software Development Process has a complexity that is process-inherent. Soft System Engineering is a response to address this complexity and to support the application of user-driven methods in an open innovation environment. This approach allows the development of a systematic interaction with users to generate new offerings and to improve previous products and services in order to create value and differentiation.
Web 2.0 and its Implications on Globally Competitive Business Model
Authors: Joshi Sudhanshu
Published: July 2013

Considering the impact of using social media, both internal and external implications for company operations are required to be explored. The chapter explores how social media is used to enable innovation practices in company internal operations as well as external stakeholders. In addition, the objective of the study is to evaluate the need and scope of Web 2.0 behind the restructuring of the business model, with major emphasis on implementing a user-centric business model. The research questions include: (a) What are the Critical Success Factors (CSF) responsible for attracting and engaging users in Web 2.0-oriented business processes and practices?; (b) Identifying the scope of effective Web 2.0-based strategies to overcome internal resistance at operational as well firm level during deployment of new business model. The chapter also discusses the influence of Web 2.0 concepts in the Web-strategy formulation for organizations with differing requirements, characteristics, and objectives. Considering four types of Web-based business models (Wirtz, 2010), namely (a) content-oriented business model, (b) commerce-oriented business model, (c) context-oriented business model, and (d) connection-oriented business model. The chapter defines the implementation of Web 2.0-based technological strategies in evolving the business model of the firm.
Social Networks and Internet Communities in the Field of Geographic Information and Their Role in Open Data Government Initiatives
Authors: Díaz Paula , Masó Joan
Published: July 2013

Users are playing an increasingly relevant role in geospatial data production. The traditional procedure for creating cartography, mainly by experts in official mapping agencies, has evolved into a more participative process for generating data: neogeography. Technology and the Internet are now user-friendly for a wide range of people who have become active users of global networks, such as GEOSS, INSPIRE, Eye On Earth, and EarthCube, and official producers need to adapt to the new era of openness, collaboration, and hybrid maps by adopting open standards. Although the creation of geospatial information is notably growing worldwide, and is enhanced by user-generated content, we may wonder whether this is a feasible alternative to official cartography. This chapter reviews the main geospatial networks based on both bottom-up and top-down data creation approaches, as well as the potentialities and limitations of user-generated content in the scientific field and in decision-making organisms.
Fungal symbiont of firebrats (Thysanura) induces arrestment behaviour of firebrats and giant silverfish but not common silverfish
Authors: Woodbury Nathan , Gries Gerhard
Published: July 2013

We have recently shown that firebrats, Thermobia domestica (Packard) (Thysanura: Lepismatidae), carry, and deposit with their faeces, the symbiotic bacterium Enterobacter cloacae (Jordan 1890) Hormaeche and Edwards 1960 (Enterobacteriaceae) and the symbiotic fungus Mycotypha microspora Fenner, 1932 (Mycotyphaceae), and that these microbes induce arrestment behaviour and aggregation of firebrats. Here, we tested whether giant silverfish, Ctenolepisma longicaudata Escherich (Thysanura: Lepismatidae), and common silverfish, Lepisma saccharina (Linnaeus) (Thysanura: Lepismatidae), also arrest in response to these two microbes. In dual-choice bioassays, E. cloacae arrested firebrats but not giant silverfish or common silverfish, whereas M. microspora arrested firebrats and giant silverfish but not common silverfish. As close relatives, firebrats and giant silverfish have similar microclimate and nutrient requirements and may use M. microspora as the same aggregation cue when they aggregate in hot and humid microclimates where M. microspora proliferates and breaks down cellulose. As a more distant relative to firebrats and giant silverfish, common silverfish seem to require a different as yet unknown aggregation cue or signal, possibly one that is indicative of the type of microclimate (room temperature; high humidity) they prefer.

Abstract - A population of Gonipterus scutellatus sensu lato (Coleoptera Curculionidae), a pest of Eucalyptus spp., was found on February 2011, for the first time in Tuscany, in the Integral Natural Reserve of Montecristo Island (Central Italy) as the possible result of a late 19thcentury introduction on eucalyptus trees from Australia.Riassunto - Gonipterus scutellatus s. l. nell’isola di Montecristo (Toscana): il suo arrivo nella regione Paleartica dovrebbe essere retrodatato al XIX secolo? (Coleoptera Curculionidae). Gonipterus scutellatus s. l. (Coleoptera Curculionidae), un insetto dannoso per varie specie di Eucalyptus, è stato trovato, per la prima volta in Toscana, nel Febbraio 2011, nella Riserva Naturale Statale Integrale di Montecristo, isola del Parco Nazionale dell’Arcipelago Toscano. L’introduzione di questa specie potrebbe risalire alla fine del XIX secolo, con l’importazione di piante di Eucalyptus direttamente dall’Australia.
