Investigating the influence of hydrogen on stress corrosion cracking of 2205 duplex stainless steel in sulfuric acid by electrochemical impedance spectroscopy
Authors: Zheng Chuanbo , Yi Guo 
Published: February 2017

AbstractAs a nondestructive and sensitive method, electrochemical impedance spectroscopy (EIS) can be used to investigate the passivation and breakdown of passive films on steel. In this study, EIS, combined with slow strain rate test and scanning electron microscopy, was employed to study the stress corrosion cracking (SCC) behavior of 2205 duplex stainless steel in 0.5 m sulfuric acid solution under hydrogen-charging conditions. Results showed that the corrosion resistance of passive film on the hydrogen-charged specimen was lower than that for the specimen with no hydrogen charge. Hydrogen-induced cracking was evident after the specimens had been charged for 24 h. The phase shift in EIS, calculated from frequencies between 0.1 and 10 Hz, could be used to monitor the SCC process.
Mesearch and the Gothic Imagination
Authors: Raw Laurence 
Published: February 2017

Abstract
Based on a transformational moment in 2013, this piece calls for a revision in research methods, with the attention focused less on critical objects and more on one’s personal response to them. This technique of mesearch, with the self placed at the center of one’s agenda, offers unique opportunities for self-analysis through redefining one’s relationship to literature. The point is exemplified through a case-study of Mary Shelley’s Frankenstein.

Authors: Alsaadi Mohamad , Erkliğ Ahmet , Bulut Mehmet 
Published: February 2017

Abstract
Fracture toughness of particle-filled polymer composite beams with different particle content for varying of crack inclination angles was investigated in mode I and mode III loading conditions. The beams were tested using three-point bending test with crack inclination angles of 30°, 45°, 75°, and 90°. Sewage sludge ash (SSA), fly ash (FA), and silicon carbide (SiC) microparticles were used as toughening fillers with 5, 10, 15, and 20 wt% contents of the total weight of the polymer composites. The scanning electron microscope (SEM) micrographs showed that a good indication was observed for dispersion of FA, SSA, and SiC particles within the polymer matrix. The critical crack tip stress intensity factors K
Ic (crack angle 90°) and K
IIIc, and the critical strain energy release rates G
Ic and G
IIIc were calculated and their results were compared. The mode I and mode III fracture toughness of the particulate polyester composite were improved by addition of particulate fillers. The maximum values of fracture toughness mode I (K
Ic and G
Ic) and mode III (K
IIIc and G
IIIc) were recorded at particle content of 5 wt% polymer composites.

Authors: Larose Guylaine , Levy Arielle , Bailey Benoit , Cummins-McManus Barbara , Lebel Denis , Gravel Jocelyn 
Published: February 2017

OBJECTIVE:To evaluate whether a clinical aid providing precalculated medication doses decreases prescribing errors among residents during pediatric simulated cardiopulmonary arrest and anaphylaxis.METHODS:A crossover randomized trial was conducted in a tertiary care hospital simulation center with residents rotating in the pediatric emergency department. The intervention was a reference book providing weight-based precalculated doses. The control group used a card providing milligram-per-kilogram doses. The primary outcome was the presence of a prescribing error, defined as a dose varying by ≥20% from the recommended dose or by incorrect route. Residents were involved in 2 sets of paired scenarios and were their own control group. Primary analysis was the difference in mean prescribing error proportions between both groups.RESULTS:Forty residents prescribed 1507 medications or defibrillations during 160 scenarios. The numbers of prescribing errors per 100 bolus medications or defibrillations were 5.1 (39 out of 762) and 7.5 (56 out of 745) for the intervention and control, respectively, a difference of 2.4 (95% confidence interval [CI], −0.1 to 5.0). However, the intervention was highly associated with lower risk of 10-fold error for bolus medications (odds ratio 0.27; 95% CI, 0.10 to 0.70). For medications administered by infusion, prescribing errors occurred in 3 out of 76 (4%) scenarios in the intervention group and 13 out of 76 (22.4%) in the control group, a difference of 13% (95% CI, 3 to 23).CONCLUSIONS:A clinical aid providing precalculated medication doses was not associated with a decrease in overall prescribing error rates but was highly associated with a lower risk of 10-fold error for bolus medications and for medications administered by continuous infusion.
A Zselic digitális lábnyomai. Webes és közösségimédia-kutatás a régió platformjairól és reprezentációjáról
Authors: Fehér Katalin 
Published: February 2017

A Zselic digitális lábnyomát hálózatkutatási módszertannal vizsgáló projekt célja az volt, hogy összegezze, elemezze és felmutassa a régió már felépült azonosítóit, webes, közösségi és témahálózatait, illetve reprezentációit. Cél volt továbbá erre alapozva ajánlásokat megfogalmazni egy konstruktív, célzott üzenetekre épülő digitális identitás felépítéséhez, mely online eszközökkel támogatja a térség turizmusát, gazdaságát, kulturális és természeti értékeinek védelmét és közösségeinek komfortját.
A kutatás két alapkérdésre épül. Az első alapkérdés, hogy tartozik-e a Zselic régió digitális identitásához egységes platform-, adat- vagy reprezentációs azonosítókészlet. A második alapkérdés, hogy melyek azok az interaktív platformok, ahol a Zselic regionális digitális identitása reprezentálódik. Vizsgáltuk azokat az azonosító funkciókat, témahálózatokat és reprezentációkat, melyek a térség digitális identitását hosszabb távon meghatározzák. Vizsgáltuk továbbá azokat az interaktív, kezdeményező és újításokra nyitott megoldásokat is, melyek hálózatokat és közösségeket építenek, illetve erősítik a régió vonzerejét és életminőségét. A kutatás kevert mintavételi eljárással készült és megismételhető a tanulmány alapján. A gyorsan változó digitális környezetek és a folyamatosan frissülő tartalom- és adatfolyamok azonban különböző kimenetekhez vezethetnek. A kapott eredmények alapján a meglévő, jó keresési és találati előzményekkel bíró, tartalmilag és funkcionálisan összefoglaló jellegű webes csomópontok erősítése javasolt, valamint a régió közösségei integrált online felületekkel és hálózati összeköttetésekkel támogathatók. Emellett újítások bevezetése és a fiatalabb generációk platformjain való erősítés szükséges.
Impact of Partial‐Mouth Periodontal Examination Protocols on the Association Between Gingival Bleeding and Oral Health–Related Quality of Life in Adolescents

Published: February 2017

Background: It is not clear how using partial‐mouth periodontal examination (PMPE) protocols affects estimates of the association between gingival bleeding (GB) and oral health–related quality of life (OHRQoL). The aim of the present study is to assess impact of different PMPEs on the association between GB and OHRQoL in 12‐year‐old adolescents.Methods: A total of 1,134 adolescents were evaluated for clinical and subjective variables. GB was determined by full‐mouth examination (FME) of six sites (disto‐buccal [DB], mid‐buccal [B], mesio‐buccal [MB], disto‐lingual [DL], mid‐lingual, and mesio‐lingual [ML]) and different PMPEs were calculated using a 15% cut‐off point: 1) full‐mouth (MB‐B‐DB/MB‐B‐DL); 2) two diagonal quadrants (six sites/MB‐B‐DB/MB‐B‐DL); 3) two randomly selected half‐mouth quadrants (six sites/MB‐B‐DB/ MB‐B‐DL/MB‐DB‐ML‐DL); and 4) the community periodontal index. OHRQoL was assessed using the Child Perceptions Questionnaire (CPQ11‐14). Adjusted negative binomial regression models were used to calculate the rate ratio of CPQ11‐14 scores for each PMPE.Results: Adolescents with GB showed significantly poorer OHRQoL than their counterparts when FME was used. In contrast, more than half of PMPE protocols did not detect significant associations between GB and CPQ11‐14 scores in the adjusted analysis.Conclusions: Using PMPE to assess GB in adolescents significantly affects associations with OHRQoL outcomes, depending on the protocol used. PMPEs that evaluated MB‐B‐DL sites of randomly selected half‐mouth quadrants (1 or 2 and 3 or 4) achieved results closer to those obtained with FME.
Why Do Academics Use Academic Social Networking Sites?

Published: February 2017

<p class="3">Academic social-networking sites (ASNS) such as Academia.edu and ResearchGate are becoming very popular among academics. These sites allow uploading academic articles, abstracts, and links to published articles; track demand for published articles, and engage in professional interaction. This study investigates the nature of the use and the perceived utility of the sites for academics. The study employs the <em>Uses and Gratifications</em> theory to analyze the use of ASNS. A questionnaire was sent to all faculty members at three academic institutions. The findings indicate that researchers use ASNS mainly for consumption of information, slightly less for sharing of information, and very scantily for interaction with others. As for the gratifications that motivate users to visit ASNS, four main ones were found: self-promotion and ego-bolstering, acquisition of professional knowledge, belonging to a peer community, and interaction with peers.<em> </em></p>
Differences in the Students’ Perceptions on the Teaching of Neuroanatomy in a Medical Curriculum Organized by Disciplines and an Integrated Medical Curriculum
Authors: Arantes Mavilde , Barbosa Joselina , Ferreira Maria Amélia 
Published: February 2017

Introduction: On the subject of curriculum reform, most European medical schools are moving away from an educational approach consisting of discipline-based courses to an integrated curriculum. The aim of this study was to compare, in the Faculty of Medicine of the University of Porto, Portugal, the teaching of neuroanatomy in a medical curriculum organized by disciplines and in an integrated medical curriculum.Material and Methods: Two hundred sixty one students who completed the Curricular Unit with a discipline-based approach (Neuroanatomy) and 202 students who completed it with an integrated approach (Morphophysiology of the Nervous System) were asked to complete a questionnaire on their perceptions about the Curricular Unit.Results: Our study showed that students of the Curricular Unit with a discipline-based approach had higher grades and evaluated it higher than students who followed the integrated approach. However, it also showed that students’ grades had a significant effect on the evaluation of the curricular unit, with students with higher grades evaluating higher than students with lower grades. Besides, the majority of the students of the Curricular Unit with an integrated approach appreciated this curriculum model and highlighted as a positive point the successful integration of contents covered in the three components of the curricular unit.Discussion: The curriculum reform led to the integration of neuroanatomy with other disciplines and resulted in a reduction of the teaching hours, a redefinition of the syllabus contents and the students’ learning objectives, the introduction of new educational methods and changes in the evaluation system.Conclusion: Our study could not prove conclusively the supremacy of one pedagogic approach to neuroanatomy over the other. Future initiatives to explore different pedagogical models in medical education are needed and should be of major concern to the medical faculty.
Behavior Changes and Gait Unsteadiness: The Value of Imaging and Prompt Neurosurgical Intervention

Published: February 2017

Cavernous angiomas are central nervous system malformations. Most common manifestations are seizures and acute focal neurological deficits. We present a case report of a seventy-one year-old man with a two-month history of behavior changes, attention deficit and indifference followed by gait unsteadiness. Neuropsychological evaluation showed severe cognitive impairment and executive dysfunction. Head computed tomography depicted a supraventricular hydrocephaly. Magnetic resonance imaging revealed a small hemorrhage, contiguous to a mesencephalic cavernous angioma, obstructing the Sylvius aqueduct, causing secondary hydrocephalus. Four months after endoscopic ventriculocisternostomy, neuropsychological evaluation showed improvement and the patient regained autonomy. Parenchyma cavernous angiomas causing direct hemorrhage and subsequent obstruction of the Sylvian aqueduct are uncommon. Sub-acute behavior and mental state abnormalities are rare first manifestations of cavernous angioma and requires high clinical suspicion for its correct diagnosis. Magnetic resonance imaging evaluation is crucial in the detection of such patients as prompt neurosurgical intervention may substantially improve cognitive function.

Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi tepung kulit manggis (TKM) dan Vitamin E (VE) di dalam ransum ayam ras petelur terhadap kualitas fisik telur selama penyimpanan pada waktu dan suhu yang berbeda. Ayam petelur diberi perlakuan pakan yaitu : R0 (ransum kontrol), R1 (R0 +1 g TKM/Kg ransum), R2 (R0 + 2 g TKM/Kg ransum) dan R3 (R0 + 200 mg VE/Kg ransum). Rancangan yang digunakan adalah rancangan acak lengkap pola faktorial 4 x 3 x 2 dengan 4 ulangan. Faktor pertama yaitu ransum, faktor kedua yaitu: waktu penyimpanan (1, 2 dan 3 minggu) dan faktor ketiga yaitu suhu penyimpanan pada refrigerator (4,13oC dan 22,50%) dan suhu ruang (27, 47oC dan 76,17%). Variabel yang diamati adalah: berat telur, persentase kerabang telur, persentase kuning telur, persentase putih telur, tebal kerabang, warna kuning telur dan Haught unit (HU). Hasil penelitian menunjukkan bahwa interaksi antara ransum, waktu dan suhu selama penyimpanan sangat nyata (P<0,01) menurunkan warna kuning telur. Waktu dan suhu penyimpanan sangat nyata (P<0,01) menurunkan HU dan meningkatkan persentase kuning telur. Interaksi waktu dan suhu penyimpanan nyata (P<0,05) menurunkan persentase putih telur. Tebal kerabang nyata (P<0,05) meningkat dipengaruhi oleh ransum dan sangat nyata (P<0,01) meningkat dipengaruhi oleh waktu penyimpanan. Berat telur dan persentase kerabang telur tidak dipengaruhi oleh ransum, waktu dan suhu penyimpanan. Kesimpulan penelitian adalah suplementasi tepung kulit manggis dan Vitamin E di dalam ransum ayam ras petelur strain Lohmann secara umum tidak mempengaruhi kualitas fisik telur (kecuali warna kuning telur dan tebal kerabang) yang disimpan pada waktu dan suhu yang berbeda. Kualitas fisik telur lebih utama dipengaruhi oleh waktu dan suhu penyimpanan yang berbeda. Suhu dan kelembaban terbaik untuk penyimpanan telur adalah 4,13oC dan 22,50% pada refrigerator, pada kondisi ini telur dapat disimpan selama 21 hari.
