Zeleno izobraževanje na ljudski univerzi v Ajdovščini
Authors: Volk Mojca
Published: April 2015

Green Education – Back to the Nature je naslov projekta, v katerem razvijamo nove prakse izobraževanja za trajnostni razvoj. V začetku leta 2013 smo v sodelovanju s partnerji iz Poljske, Francije, Malte, Turčije, Italije, Velike Britanije in Španije v okviru programa Evropskih skupnosti Vseživljenjsko učenje, Razpis VŽU 2013, sektorski program Grundtvig, akcija Učna partnerstva prijavili projekt z naslovom Green Education – Back to the Nature. Prijava je bila uspešna, vendar ne z vsemi partnerji. Odpadle so namreč organizacije iz Francije in z Malte. Slovenija sodeluje v partnerstvu kot koordinatorica projekta. Partnerski sestanki so predvideni v vseh sodelujočih državah. Zaključno srečanje bo maja 2015 v Sloveniji.
Karierni centri na univerzi – prostori neformalnega učenja za študente
Authors: Žnidaršič Žagar Sabina
Published: April 2015

V Sloveniji se v zadnjih letih srečujemo z zastoji pri vključevanju mladih (tudi) s terciarno izobrazbo na trg dela. Na zaposljivost posameznika poleg zunanjih dejavnikov, na katere nimamo neposrednega vpliva, vplivajo osebnostne lastnosti, prizadevanja, volja in podobno. Dobra zaposljivost pomeni opolnomočenje, da posameznik skozi proces vseživljenjskega učenja nastopa na trgu dela trajnostno, tako da uresničuje svoje karierne cilje ter s svojim ustvarjalnim delom prispeva k svojemu zadovoljstvu in uspehu ter uspehu skupnosti. Na slovenskih univerzah so bili karierni centri ustanovljeni, da bi pripomogli k dvigu zaposljivosti diplomantov. Po petih letih delovanja Kariernega centra Univerze v Ljubljani (od leta 2008) prihajamo do podobnih izkušenj kot v drugih kariernih centrih evropskih univerz, da je učinkovitost spodbujanja in omogočanja razvoja dobre zaposljivosti večja tedaj, ko so karierni centri s svojimi aktivnostmi intenzivneje vključeni v same študijske procese.
Uničevanje mišljenja
Authors: Sajovic Tomaž
Published: April 2015

Današnjo neoliberalno avtoritarno družbo obvladuje – če uporabimo besednjak Slavoja Žižka iz besedila Leninova izbira (2010) – nezapisani Denkverbot, »prepoved« kritičnega mišljenja, ki jo zgodovinsko ponazarja znamenita izjava angleške ministrske predsednice Margaret Thatcher: »Neoliberalizem nima alternative.« Neoliberalna ekonomska in družbena kontrarevolucija se je v 60. letih spočela na Oddelku za ekonomijo Univerze v Chicagu, njen najpomembnejši zagovornik pa je bil ameriški ekonomist in Nobelov nagrajenec za ekonomijo Milton Friedman. Friedmanov program je bil skrajno konservativen: »Prvič, vlade morajo odpraviti vsa določila in regulativo, ki preprečuje kopičenje dobička. Drugič, odprodati morajo vse premoženje, ki ga imajo v lasti in bi ga korporacije lahko vodile z dobičkom. In tretjič, financiranje socialnih programov morajo dramatično zmanjšati.« To popolnoma nečloveško ideologijo, ki se je »točno ujemala z interesi velikih multinacionalk«, je Friedman »skrbno « skril v akademizacijski »jezik matematike in znanosti« in jo s tem »preoblikoval« v nepristransko ekonomsko znanost. Neoliberalno urejanje gospodarstva tako naj ne bilo več stvar subjektivnih človeških odločitev, ampak »le« še izpolnjevanje znanstveno ugotovljenih naravnih zakonov. O njem zato naj ne bi bilo več mogoče »dvomiti« niti naj ne bi bilo več »smisla« o njem kritično razmišljati. Predpostavka je, da neoliberalna ekonomska ideologija lahko parazitira na znanosti le zato, ker so v neoliberalizmu tudi znanosti same postale »ideologija«. Švicarsko-kanadski sociolog in filozof Michel Freitag (1935–2009) jih je v svoji knjigi Brodolom univerze (1995, v slovenskem prevodu 2010) imenoval tehnoznanosti: »Znanost se ne ukvarja več s spoznavanjem sveta, temveč z napovedovanjem učinkov, ki jih bodo v svetu povzročili naši praktično smotrni posegi.« Tehnoznanosti se ukvarjajo torej s problemi, ki niso plod znanstvenoteoretičnega preučevanja, ampak so jim jih od zunaj ideološko vsilile znanstvene politike (pri nas teme vsiljujejo na primer razpisi za znanstvene projekte). Tehnoznanstveno raziskovanje se mora izogibati teoretskemu razmišljanju, razmišljati pa mu tudi ni treba več o svojem lastnem početju. Znanost – izjeme seveda obstajajo – tako ne ustvarja več ničesar novega. Ustanove znanstvene politike so znanosti preprečile njeno znanstveno in družbeno kritičnost. Znanost je postala nemisleča, nepolitična in nečloveška. Znanstvenike pa so take znanstvene politike oropale poklicnega in človeškega dostojanstva in smisla. Pričujoči esej skuša vsesplošno neoliberalno uničevanje mišljenja misliti.

Authors: Valandro Luiz Felipe , Bergoli César Dalmolin , Druck Carolina Ceolin , Pereira Gabriel Kalil Rocha
Published: April 2015

Aim

To evaluate the effect of fiber post surface treatments on push-out bond strength between fiber post and root dentin.

Materials and methods

Sixty bovine mandibular teeth (N = 60) were sectioned (16 mm), prepared (12 mm), embedded with acrylic resin and then allocated into six groups (n = 10): Gr1- Silane coupling agent (Sil) + Conventional resin cement AllCem (AlC); Gr2- Sil + Conventional resin cement RelyX ARC (ARC); Gr3- tribochemical silica coating (TBS) + AlC; Gr4– TBS + ARC; Gr5- No treatment (NT) + AlC; Gr6– NT+ ARC. Specimens were sectioned in four slices (2 mm) and submitted to push-out test. Fracture analyses were executed at x200. The values of the push-out bond strength were submitted to two-way ANOVA and Tukey test (á = 0.05).

Results

Resin cement did not affect the bond strength values (p = 0.9674), fiber post surface treatment affected the push-out bond strength (p = 0.0353), interaction between factors did not affected the values (p = 0.338). Tukey test did not show differences between the groups. Adhesive failure between cement and dentin was predominantly.

Conclusion

The fiber post surface treatment appears have no influence on bond strength between fiber post and root dentin.

Clinical significance

The tested fiber posts surface treatment appears do not influence the fiber post bond behavior.

Published: April 2015

Introduction

Giant cell lesions are characterised histologically by multinucleated giant cells in a background of ovoid to spindleshaped mesenchymal cells. There is a major debate whether these lesions are separate entities or variants of the same disease. Our aim was to study the nature of multinucleated and mononuclear cells from peripheral giant cell granuloma (PGCG), and central giant cell granuloma (CGCG) and giant cell tumor (GCT) of long bones using immunohistochemistry evaluation and to determine whether there is a correlation between recurrence and the markers used.

Materials and methods

Ki-67, p53, Vimentin, smooth muscle specific actin, CD68 and alpha-1-antichymotrypsin were used to study 60 giant cell lesions. These included 26 CGCG, 28 PGCG, and 6 GCT cases using an avidin-biotin-complex immunohistochemistry standard method.

Results

All studied cases showed the same results except the percentage of Ki-67 positive mononuclear cells in PGCG was significantly higher than that of both CGCG and GCT (p < 0.05). Interestingly, no statistical correlation between recurrence and the markers used was found.

Conclusion

Our results may suggest that these lesions have the same histogenesis. The mononuclear stromal cells, both histiocytic and myofibroblastic, are thought to be responsible for the behavior of these lesions whereas the multinucleated cells are considered as reactive. This might support the argument that PGCG, CGCG and GCT are different variants for the same disease. Further studies using molecular techniques are required to elucidate why some of these lesions behave aggressively than others.

Self-reported Occupational Health Problems among Libyan Dentists
Authors: Arheiam Arheiam , Ingafou Mohamed
Published: April 2015

Objectives

To investigate the prevalence of the most common occupation-related health problems as well as factors associated with their incidence among dental practitioners.

Materials and methods

A cross-sectional, questionnairebased survey of Libyan dental practitioners. Participants provided information regarding their experience of occupationally related problems they encountered over the past 12 months which included inquiries about musculoskeletal pain, percutaneous injuries, allergy, eye and sight problems, and hearing problems.

Results

Musculoskeletal problems were the most frequently reported (48.2%), followed by percutaneous injuries (35%), eye problems (22%), allergy (11%) and hearing problems (7.6%). Musculoskeletal problems were significantly higher among dentists who work in private sector, full timer as well as those who prefer to work in a sitting position (p = 0.021, 0.027 and 0.008, respectively). Practitioners with less than 5 years in service reported significantly higher percentage of percutaneous injuries (p = 0.027) than their senior counterparts, whereas practitioners who spent more than 10 years in service were more likely to suffer from visual disturbances (p = 0.033).

Conclusion

The findings of this study indicate that musculoskeletal problems and percutaneous injuries are the most commonly reported occupational health problems among dentists, whereas allergic reactions and hearing problems are the least reported ones.

Clinical significance

Dentists should use alternate working positions to minimise musculoskeletal problems and adopt more effective strategies to prevent percutaneous injuries particularly among novices.

Students’ Self-assessment: A Learning Tool and Its Comparison with the Faculty Assessments
Authors: Habib Syed Rashid , Sherfudhin Haneef
Published: April 2015

Objective

This study compared the student's self-grades versus the examiners grades, inter examiner grades and grades of anterior with posterior teeth in a preclinical prosthodontic course.

Methods

75 students and 2 examiners participated in the study. The students prepared one anterior (upper central incisor) and one posterior (lower first molar) teeth for full veneer crowns in allocated time of 2 hours and 30 minutes. After the preparations, the students self-graded their preparations based on criteria-based evaluation forms. The examiners also completed the grading for the prepared teeth. All the grades were recorded, comparisons were made using SPSS version 21 and results tabulated.

Results

The means of grades (8.32) by the students themselves were found to be higher compared to the examiners grades (7.3) for the anterior as well as posterior teeth. Comparison of the grades for the anterior/posterior teeth and the overall grades showed a statistically significant difference (p = 0.000). A moderate correlation (0.399) and a strong correlation (0.601) were found between the grades of the faculty and the students for the anterior and posterior teeth respectively. The overall grading for the anterior and posterior teeth by the two faculty members showed no statistically significant difference (p = 0.053) and a very strong correlation (0.784). The results of the test showed a significant difference (p = 0.001) between the overall grading for anterior and posterior teeth.

Conclusion

Students tended to grade their teeth preparations higher compared to the examiner grades, inter examiner variation in the grades existed and the grades of the anterior teeth were higher compared to the posterior teeth.

Published: April 2015

Glass ionomer cements (GICs) are restorative materials, which clinical use has increased significantly during the last decade. The aim of the present study was to analyze the chemical constitution and surface morphology of four glass ionomer cements: Maxxion R, VitroFill, Vidrion R and Vitremer. Twelve polyethylene tubes with an internal diameter of 3 and 3 mm in length were prepared, filled and then transferred to a chamber with 95% relative humidity and a temperature of 37°C. The surface morphology of the tested materials was examined by scanning electron microscopy (SEM) and main components were investigated by energy-dispersive X-ray microanalysis (EDX). Scanning electron microscopy revealed irregular and rough external surface. Cracking was not observed. The main constituents were found to be aluminum, silicon, calcium, sodium and fluoride. Phosphorus, sulfur and barium were only observed in Vidrion R, while chlorine were only observed in Maxxion R. Elemental mapping of the outer surface revealed high concentration of aluminum and silicon. Significant irregularities on the surface of the tested materials were observed. The chemical constitution of all GIC was similar.

Endodontic Management of C-shaped Root Canal System of Mandibular First Molar by using a modified Technique of Self-adjusting File System
Authors: Helvacioglu-Yigit Dilek
Published: April 2015

Aim

C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth.

Background

This case report presents endodontic management of a mandibular first molar with a C-shaped canal system.

Case report

Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology.

Clinical significance

The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.

Interradicular Septum as Guide for Pilot Drill in Postextractive Implantology: A Technical Note
Authors: Haddad Elias El , Lauritano Dorina , Carinci Francesco
Published: April 2015

The extraction of teeth results in rapid bone resorption both vertically and horizontally in the first month. The loss of alveolar ridge reduces the chance of implant rehabilitation. The atraumatic extraction, implant placement in extraction socket, and an immediate prosthesis have been proposed as alternative therapies to maintain the volume and contours tissue and reduce time and cost of treatment. Thus, this paper aims to present a clinical case where the extraction was performed using interradicular septum as guide for pilot drill in postextractive implantology with implant placement and immediate provisionalization in a inferior molar. The advantages of this technique are to place the implant exactly in the center of the alveolar ridge, to mantain the edges of the alveolar ridge and reduce postextractive bone resorption, and has great advantages in final prosthetic rehabilitation.

Comparing Caregiver and Clinician Predictions of Fitness to Drive in People With Alzheimer’s Disease
Authors: Bixby Kimberly , Davis Jennifer D. , Ott Brian R.
Published: April 2015

This observational study investigated family caregiver and clinician ratings of 75 drivers with Alzheimer’s disease against scores on a standardized road test and a naturalistic driving evaluation. Clinician ratings by a physician specialized in dementia were significantly associated with road test error scores (r = .25, p = .03) but not naturalistic driving errors or global ratings of road test and naturalistic driving performance. Caregiver ratings were unrelated to either driving assessment, with two exceptions; adult child ratings of driving ability were correlated with road test error scores (r = .43, p = .02), and spousal ratings were inversely correlated with global ratings. Clinician ratings of driving competence were modestly correlated with road test performance, but caregiver ratings were more complex. Adult children may be more accurate reporters of driving ability than spouses, possibly because of less personal bias, but the reasons behind this discrepancy need further investigation.

Published: April 2015

OBJECTIVE. We developed and investigated the psychometric properties of the Lifestyle History Questionnaire (LHQ), a self-report instrument designed to measure the extent of occupational dysfunction attributable to substance abuse.

METHOD. The instrument was developed using concepts in the ecological models of occupational therapy and in the work of William L. White, who defined addiction culture in terms of the patterns of life in context. We analyzed data from two field tests using both classical test theory and item response theory.

RESULTS. The final version of the instrument has 70 items, 1 unifying construct, and 8 subscales. We found it to be valid and reliable (α = .93) for measuring the extent of occupational dysfunction and specific areas of strengths and weaknesses.

CONCLUSION. The LHQ is a promising new instrument, the first of its kind to measure occupational dysfunction in context for people with substance addictions.

Published: April 2015

Setting goals can be a valuable skill to self-manage multiple sclerosis (MS) fatigue. A better understanding of the goals set by people with MS after completing a fatigue management program can assist health care professionals with tailoring interventions for clients. This study aimed to describe the focus of goals set by people with MS after a teleconference-delivered fatigue management program and to evaluate the extent to which participants were able to achieve their goals over time. In total, 485 goals were set by 81 participants. Over a follow-up period, 64 participants rated 284 goals regarding progress made toward goal achievement. Approximately 50% of the rated goals were considered achieved. The most common type of goal achieved was that of instrumental activities of daily living. Short-term goals were more likely to be achieved. This study highlights the need for and importance of promoting and teaching goal-setting skills to people with MS.
Effects of Deep Pressure Stimulation on Physiological Arousal
Authors: Reynolds Stacey , Lane Shelly J. , Mullen Brian
Published: April 2015

Deep pressure stimulation has been used in therapeutic practice because of the assumption that it changes physiological arousal. The purpose of this study was to test the effects of deep pressure stimulation, applied with a Vayu Vest (Therapeutic Systems), on both autonomic arousal and performance in a normative adult sample. A repeated-measures, repeated-baseline design was used with participants completing a performance test before and after deep pressure application. A convenience sample of 50 adults participated in the study. Results showed that wearing the Vayu Vest for even short periods of time reduced sympathetic arousal and non–stimulus-driven electrical occurrences. Concomitant increases in parasympathetic arousal were found. Performance improvements were noted after wearing the Vayu Vest, potentially because of changes in arousal. We conclude that deep pressure stimulation is capable of eliciting changes in autonomic arousal and may be a useful modality in diagnostic groups seen by occupational therapy practitioners.
Role of Sonographic Imaging in Occupational Therapy Practice
Authors: Roll Shawn C.
Published: April 2015

Occupational therapy practice is grounded in the delivery of occupation-centered, patient-driven treatments that engage clients in the process of doing to improve health. As emerging technologies, such as medical imaging, find their way into rehabilitation practice, it is imperative that occupational therapy practitioners assess whether and how these tools can be incorporated into treatment regimens that are dually responsive to the medical model of health care and to the profession’s foundation in occupation. Most medical imaging modalities have a discrete place in occupation-based intervention as outcome measures or for patient education; however, sonographic imaging has the potential to blend multiple occupational therapy practice forms to document treatment outcomes, inform clinical reasoning, and facilitate improved functional performance when used as an accessory tool in direct intervention. Use of medical imaging is discussed as it relates to occupational foundations and the professional role within the context of providing efficient, effective patient-centered rehabilitative care.
Secondary organic aerosol formation from photochemical aging of light-duty gasoline vehicle exhausts in a smog chamber

Published: April 2015

Abstract. In China, fast increase in passenger vehicles has procured the growing concern about vehicle exhausts as an important source of anthropogenic secondary organic aerosols (SOA) in megacities hard-hit by haze. However, there are still no chamber simulation studies in China on SOA formation from vehicle exhausts. In this study, the SOA formation of emissions from two idling light-duty gasoline vehicles (LDGVs) (Euro 1 and Euro 4) in China was investigated in a 30 m3 smog chamber. Five photo-oxidation experiments were carried out at 25 °C with the relative humidity around 50%. After aging at an OH exposure of 5 × 106 molecules cm−3 h, the formed SOA was 12–259 times as high as primary OA (POA). The SOA production factors (PF) were 0.001–0.044 g kg−1 fuel, comparable with those from the previous studies at the quite similar OH exposure. This quite lower OH exposure than that in typical atmospheric condition might however lead to the underestimation of the SOA formation potential from LDGVs. Effective SOA yield data in this study were well fit by a one-product gas-particle partitioning model and quite lower than those of a previous study investigating SOA formation form three idling passenger vehicles (Euro 2–Euro 4). Traditional single-ring aromatic precursors and naphthalene could explain 51–90% of the formed SOA. Unspeciated species such as branched and cyclic alkanes might be the possible precursors for the unexplained SOA. A high-resolution time-of-flight aerosol mass spectrometer was used to characterize the chemical composition of SOA. The relationship between f43 (ratio of m/z 43, mostly C2H3O+, to the total signal in mass spectrum) and f44 (mostly CO2+) of the gasoline vehicle exhaust SOA is similar to the ambient semi-volatile oxygenated organic aerosol (SV-OOA). We plot the O : C and H : C molar ratios of SOA in a Van Krevelen diagram. The slopes of ΔH : C/ΔO : C ranged from −0.59 to −0.36, suggesting that the oxidation chemistry in these experiments was a combination of carboxylic acid and alcohol/peroxide formation.
Particulate organic nitrates observed in an oil and natural gas production region during wintertime

Published: April 2015

Abstract. Organic nitrates in both gas and condensed (aerosol) phases were measured during the Uintah Basin Winter Ozone Study from January to February in 2012. A high degree of correlation between total aerosol volume at diameters less than 500 nm and the particulate organic nitrate concentration indicates that organic nitrates are a consistent, if not dominant, fraction of fine aerosol mass. In contrast, a similar correlation with sub 2.5 μm aerosol volume is weaker. The C : N atomic ratio inferred from field measurements of PM2.5 and particulate organic nitrate is 34 : 1. Calculations constrained by the observations indicate that both condensation of gas phase nitrates and heterogeneous reactions of NO3 / N2O5 are responsible for introducing organic nitrate functionality into the aerosol and that the source molecules are alkanes. Extrapolating the results to urban aerosol suggests organic nitrate production from alkanes may be a major secondary organic aerosol source.
Processing of water level derived from water pressure data at the Time Series Station Spiekeroog

Published: April 2015

Abstract. The quality of water level time series data strongly varies with periods of high and low quality sensor data. In this paper we are presenting the processing steps which were used to generate high quality water level data from water pressure measured at the Time Series Station (TSS) Spiekeroog. The TSS is positioned in a tidal inlet between the islands of Spiekeroog and Langeoog in the East Frisian Wadden Sea (southern North Sea). The processing steps will cover sensor drift, outlier identification, interpolation of data gaps and quality control. A central step is the removal of outliers. For this process an absolute threshold of 0.25 m/10 min was selected which still keeps the water level increase and decrease during extreme events as shown during the quality control process. A second important feature of data processing is the interpolation of gappy data which is accomplished with a high certainty of generating trustworthy data. Applying these methods a 10 years dataset of water level information at the TSS was processed and the results were submitted to WDC MARE data base system PANGAEA (
Magnetotelluric investigation in the High Agri Valley (southern Apennine, Italy)

Published: April 2015

Abstract. In this paper we present the result of a magnetotelluric (MT) investigation carried out across the High Agri Valley (HAV), southern Italy. Several MT soundings were carried out in order to obtain a ~15 km long 2-D resistivity model with an investigation depth of ~10 km. The main aim was to provide valuable data on the geological and structural setting of the HAV. The MT model was compared with pre-existing geological, geophysical and seismic data. The MT model can be schematized as a superposition of three stack lateral varying layers with different thickness and resistivity values: a surficial low–medium resistivity layer associated with the Quaternary deposits and to the allochthonous units; and a deeper high resistivity layer related to the Apulia Platform, separated by a thin layer connected to the mélange zone and to the Pliocene terrigenous marine deposits. Sharp lateral resistivity variations are interpreted as faults that, on the basis of accurate focal mechanism computations, display normal-faulting kinematics.
Pubertal and testicular development in the common marmoset (Callithrix jacchus) shows high individual variation

Published: April 2015

Abstract. The common marmoset (Callithrix jacchus) is a New World primate that exhibits a man-like adult testicular organization. Aims: this study examines the pubertal testicular development in the common marmoset. Material and methods: immature male common marmosets (n = 48) were monitored longitudinally for a period of 13 months. Body weight and testicular volume (TV) were recorded, and testosterone levels were analyzed by an in-house radioimmunoassay. After 13 months the testes were collected, fixed and embedded in paraffin (n = 48). Histological and morphometric data were determined. Results: the first 6 months exhibited a rapid rise in body weight but not in TV. At 7 months a threefold increase in testosterone levels was observed. After 7 months the first few animals displayed rapid testis growth (> 250 mm3 at 10 months), while others exhibited no or slow pubertal development (≤ 100 mm3 at 10 months). Histological features confirmed an individually variable pattern of testicular development. Parallel with the rise in serum testosterone levels, an increase in the diameter of seminiferous tubules and an appearance of a tubular lumen as well as meiotic germ cells were encountered. The onset and the kinetics of testicular development were highly variable between individual animals in the colony. Epididymal sperm were first observed at 12 months of age. The TV and seminiferous tubule diameter showed continued growth after 12 months of age, especially in the animals developing with a delay after 7 months. Conclusions: pubertal onset in the common marmosets occurs at the earliest at 6 months of age and is hallmarked by sudden threefold increase in serum testosterone levels and a significant rise in the TV. Pubertal testis growth is characterized by an appearance of a tubular lumen and of primary and secondary spermatocytes. Spermatogenesis is qualitatively accomplished at the earliest at 12 months of age. A very high individual difference in onset and kinetics of pubertal development renders the age a very poor prognostic factor to determine the pubertal status of individual marmosets.
Thermal structure and basal sliding parametrisation at Pine Island Glacier – a 3-D full-Stokes model study
Authors: Wilkens N. , Behrens J. , Kleiner T. , Rippin D. , Rückamp M. , Humbert A.
Published: April 2015

Abstract. Pine Island Glacier is one of the fastest changing glaciers of the Antarctic Ice Sheet and therefore of scientific interest. The glacier holds enough ice to raise the global sea level significantly (~ 0.5 m) when fully melted. The question addressed by numerous modelling studies of the glacier focuses on whether the observed changes are a start of an uncontrolled and accelerating retreat. The movement of the glacier is, in the fast-flowing areas, dominated by basal motion. In modelling studies the parametrisation of the basal motion is therefore crucial. Inversion methods are commonly applied to reproduce the complex surface flow structure of Pine Island Glacier by using information of the observed surface velocity field to constrain, among other things, basal sliding. We introduce two different approaches of combining a physical parameter, the basal roughness, with basal sliding parametrisations. This way basal sliding is again connected closer to its original formulation. We show that the basal roughness is an important and helpful parameter to consider and that many features of the flow structure can be reproduced with these approaches.
Robotic Exploration: New Heuristic Backtracking Algorithm, Performance Evaluation and Complexity Metric
Authors: El-Hussieny Haitham , Assal Samy F.M. , Abdellatif Mohamed
Published: April 2015

Mobile robots have been used to explore novel environments and build useful maps for navigation. Although sensor-based random tree techniques have been used extensively for exploration, they are not efficient for time-critical applications since the robot may visit the same place more than once during backtracking. In this paper, a novel, simple yet effective heuristic backtracking algorithm is proposed to reduce the exploration time and distance travelled. The new algorithm is based on the selection of the most informative node to approach during backtracking. A new environmental complexity metric is developed to evaluate the exploration complexity of different structured environments and thus enable a fair comparison between exploration techniques. An evaluation index is also developed to encapsulate the total performance of an exploration technique in a single number for the comparison of techniques. The developed backtracking algorithm is tested through computer simulations for several structured environments to verify its effectiveness using the developed complexity metric and the evaluation index. The results confirmed significant performance improvement using the proposed algorithm. The new evaluation index is also shown to be representative of the performance and to facilitate comparisons.

Robots, especially humanoids, are expected to perform human-like actions and adapt to our ways of communication in order to facilitate their acceptance in human society. Among humans, rules of communication change depending on background culture: greetings are a part of communication in which cultural differences are strong. Robots should adapt to these specific differences in order to communicate effectively, being able to select the appropriate manner of greeting for different cultures depending on the social context. In this paper, we present the modelling of social factors that influence greeting choice, and the resulting novel culture-dependent greeting gesture and words selection system. An experiment with German participants was run using the humanoid robot ARMAR-IIIb. Thanks to this system, the robot, after interacting with Germans, can perform greeting gestures appropriate to German culture in addition to a repertoire of greetings appropriate to Japanese culture.

Authors: Villamón Nevot María José
Published: April 2015

Objetivos: 1.Analizar el cumplimiento del protocolo mediante el registro del 80% de los cuidados de enfermería. 2. Describir la evolución de la densidad de incidencia de NAVM durante el periodo del estudio.
Metodología: Estudio descriptivo retrospectivo de los años 2009, 2010 y 2011. Se registró la realización de los cuidados incluidos en la prevención de NAVM en todos los pacientes en tratamiento con ventilación mecánica (VM) >24 horas, considerando que estaban cumplidos si el registro era ≥ 80%. Se calculó el número de episodios NAVM por 1000 días de VM en el periodo del estudio.
Resultados: Se incluyeron un total de 94 pacientes. El cumplimiento de las medidas fue superior al 80% excepto en la valoración de la escala de Ramsay. El número de episodios de NAV por año fue 12,8 episodios por 1000 días de VM en 2008 y tras la implantación del protocolo fue de 4,57 en 2009, 6,83 en 2010 y 2,71 en 2011.
Conclusiones: 1. La frecuencia de registro de los cuidados ha sido buena. Para la mejora del registro de la valoración de la sedación, se hace necesaria la posibilidad de implantar un protocolo para el destete. 2. La incidencia de NAVM ha descendido tras la implantación del protocolo.

Conclusiones: Las/os cuidadoras/es informales poseen habilidad de cuidado con un nivel alto de conocimiento y paciencia para la labor de cuidar y ello se relaciona con la ausencia de sobrecarga. El valor se encuentra mayoritariamente en nivel medio, encontrándose relación positiva con la sobrecarga.
 

 
The incidence of injuries and exposure time of professional football club players in the Premier Soccer League during football season
Authors: Calligeris T
Published: April 2015

Background. Data on the incidence of football injuries and exposure time of players during matches and training in the South African (SA) Premier Soccer League (PSL) are lacking. Objective. To calculate the incidence of injuries and the exposure time (practice and match) of the players of a PSL team over a full season. Methods. Injury and training data of the players in the squad (N=32) were recorded on a daily basis by the medical support staff, according to the methods of the Football Medical Assessment and Research Centre (F-MARC) protocol. Results. One hundred and thirty injuries were recorded in the season. The most affected body parts were the thigh (n=27, 21%) and ankle (n=27, 21%). The overall incidence was 13.4 injuries per 1 000 player-hours. The incidence during training was 6.6 injuries/1 000 playerhours and during matches 88.9 injuries/1 000 player-hours. The most frequent injury was haematoma/contusion/bruising (n=43, 33%). Of the total injuries, 12% were recurrent. Injury through contact with another player was high (62%). Seventy-six per cent of the injuries were not associated with any violation of the laws of the game. The average time off due to injury was 8 days. The total exposure time over the full season resulted in a combined average of 18 162 minutes (~303 hours). Conclusion. These data differ from the data in European studies. Injury and exposure data measured throughout the season have the potential to identify risks and mechanisms of injuries. This study highlights the necessity for all clubs in the PSL to adopt a standardised injury monitoring programme, using standardised methodology, so that the management of professional players in SA may be improved.

Arcanes de Montréal : la métropole dans les romans de Nelly Arcan
Authors: Dupuis Gilles
Published: April 2015

Montréal est au coeur de l’oeuvre romanesque de l’écrivaine québécoise Nelly Arcan. Non seulement la métropole fournit-elle le décor à l’intrigue des quatre romans de l’auteure, mais aussi elle s’émancipe progressivement de sa seule fonction de cadre pour constituer, d’un opus à l’autre, un  topos  à part entière du récit, inséparable du sort des personnages qui y jouent leur destin. Tour à tour sordide et branchée à travers les quartiers de prédilection fréquentés par la romancière, virtuelle et fantastique dans le passage remarqué de l’autofiction à la science-fiction, la ville désirante mise en scène par Nelly Arcan ne livre pas d’emblée tous ses secrets. C’est en interrogeant les arcanes de l’oeuvre, à la lumière de  Montréal interdite  d’Alain Médam et de  Paris insolite  de Jean-Paul Cléber, que la cybermétropole arcanienne révèle sa part insoupçonnée de mystère.
Le Papineau de Louis Fréchette : l’exproprié de l’histoire
Authors: Livernois Jonathan
Published: April 2015

On note une importante fictionnalisation de la figure de Louis-Joseph Papineau (1786-1871) dans le corpus littéraire canadien-français du XIXe et du début du XXe siècle. Louis Fréchette (1839-1908), dans ses poèmes, dans le drame Papineau ainsi que dans ses Mémoires intimes, magnifie le chef du Parti patriote, lui confère un statut de grand homme politique, de la trempe de Cicéron et de Caton. Pourtant, du même souffle, la figure de Papineau est subrepticement désamorcée, déradicalisée. Dans cette étude, nous verrons les ressorts littéraires qui expliquent ce double phénomène et ce qu’ils peuvent révéler des rapports entre la politique et la littérature canadiennes-françaises puis québécoises.
Strategic Approach Model for Investigating the Cause of Maritime Accidents
Authors: ÖZDEMİR Ünal , GÜNEROĞLU Abdulaziz
Published: April 2015

It is commonly accepted that the majority of maritime causalities are caused by human factors/errors. The role of human factor in maritime accident and the possible reasons of this argument can be quantitatively evaluated based on expert knowledge and multiple criteria decision-making (MCDM) methodology. To investigate what makes the first “human factor” in ship accidents, a hybrid approach was applied in this study. Two methods, the decision-making trial and evaluation laboratory (DEMATEL) and the analytical network process (ANP) were proposed to evaluate the importance level of the human factors in maritime casualties. Quantitative evaluations of the human errors in maritime operations can greatly improve the decision-making process and reduce potential risks. As a result of this study, the top three priorities in the evaluation systems were found as: ‘ability, skills, knowledge’ (8.94%), ‘physical condition’ (8.77%), ‘weather - sea conditions’ (8.21%) and the least important criterion was ‘cargo characteristics’ (2.21%).
Web GIS for Airport Emergency Response - UML Model
Authors: Baučić Martina , Medak Damir
Published: April 2015

The main objective of integrating Web GIS in airport emergency response should be to provide the most appropriate geospatial information to all participants. Airport emergency response still needs a model that will explain its complexity: its participants, their tasks and information needs. This paper presents the UML model of airport emergency response. Such a model facilitates a common understanding of the system by participants coming from airport, police, fire brigade, etc. It also enables institutional agreements for sharing data. The developers have got specifications of geospatial data and GIS functions imposed by participants and standards. A prototype Web GIS application is developed and presented to the users for evaluation. The prototype has shown how GIS functions can improve airport emergency response. The users have shown great interest, and they have great expectations in further integration of Web GIS in airport emergency response.

Authors: Piard Juliette , Rozé Virginie , Czorny Alain , Lenoir Marion , Valduga Mylène , Fenwick Aimée L. , Wilkie Andrew O. M. , Maldergem Lionel Van
Published: April 2015

Heterozygous mutations in TCF12 were recently identified as an important cause of craniosynostosis. In the original series, 14% of patients with a mutation in TCF12 had significant developmental delay or learning disability. We report on the first case of TCF12 microdeletion, detected by array‐comparative genomic hybridization, in a 72‐year‐old patient presenting with intellectual deficiency and dysmorphism. Multiplex ligation‐dependent probe amplification analysis indicated that exon 19, encoding the functionally important basic helix‐loop‐helix domain, was included in the deleted segment in addition to exon 20. We postulate that the TCF12 microdeletion is responsible for this patient's intellectual deficiency and facial phenotype. © 2015 The Authors.

Predicting and treating stress‐Induced vulnerability to epilepsy and depression

Published: April 2015

Accumulation of stressful events can render individuals susceptible to develop epilepsy and comorbidities. Whether such vulnerability can be predicted and reversed is not known. Here we show that social defeat, although not producing depression by itself, produced in 50% of rats reduced threshold for status epilepticus (SE), accelerated epileptogenesis, and once epilepsy was induced, depression‐like profile and cognitive deficits. Low serum brain‐derived neurotrophic factor (BDNF) levels measured before SE identified this vulnerable population. Treatment with a BDNF analog before SE prevented the occurrence of comorbidities. Thus, vulnerability to comorbidities after epilepsy onset due to unresolved past stressful events may be predicted and reversed. Ann Neurol 2015;78:128–136
Carboxylic‐Acid‐Passivated Metal Oxide Nanocrystals: Ligand Exchange Characteristics of a New Binding Motif
Authors: De Roo Jonathan , Justo Yolanda , De Keukeleere Katrien , Van den Broeck Freya , Martins José C. , Van Driessche Isabel , Hens Zeger
Published: April 2015

Ligand exchange is central in the processing of inorganic nanocrystals (NCs) and requires understanding of surface chemistry. Studying sterically stabilized HfO2 and ZrO2 NCs using 1H solution NMR and IR spectroscopy as well as elemental analysis, this paper demonstrates the reversible exchange of initial oleic acid ligands for octylamine and self‐adsorption of oleic acid at NC surfaces. Both processes are incompatible with an X‐type binding motif of carboxylic acids as reported for sulfide and selenide NCs. We argue that this behavior stems from the dissociative adsorption of carboxylic acids at the oxide surface. Both proton and carboxylate moieties must be regarded as X‐type ligands yielding a combined X2 binding motif that allows for self‐adsorption and exchange for L‐type ligands.
