Inkjet Printing of Electrically Conducting Micron-Wide Lines and Transparent Conducting Films by Edge-Enhanced Twin-Deposition
Authors: Bromberg Vadim , Ma Siyuan , Singler Timothy J. 
Published: February 2013

ABSTRACTRoll-to-roll manufacturing holds the potential to rapidly and cheaply produce electronic devices in a flexible format as well as to effectively scale up production of emerging nanotechnologies. Developing scalable techniques for the efficient and effective use of solution-processed functional material is a significant factor in realizing the potential of roll-to-roll manufacturing. We present a novel inkjet deposition process developed to rapidly deposit arrays of micron-wide lines of silver nanoparticles for use as an optically transparent and electrically conducting film. The technique involves jetting a controlled number of space-overlapped drops of a dilute nanoparticle silver ink onto a substrate to form a long stable ink rivulet with two parallel and pinned edges. Subsequently, nanoparticles deposit preferentially at the two parallel rivulet edges due to edge-enhanced evaporation of the solvent. The final result is a twin-deposit of parallel continuous nanoparticle lines, each with a characteristic width less than 5μm and height less than 300 nm. The twin lines are separated by a predominantly particle-free region with the spacing between the lines ranging from 100 μm to 600 μm, where the spacing is a function of ink, substrate, and printing conditions. The effect of substrate surface and jetting parameters on nanoparticle line morphology is presented. Arrays of such lines have been printed and evaluated as potential transparent conducting films, showing an effective sheet resistance of ∼5 Ω/□. This edge-enhanced twin-deposition technique has the potential for rapid, material-efficient, and lithography-free patterned deposition of functional material for use in roll-to-roll manufacturing.

Published: February 2013

ABSTRACTElectronic systems are a very good platform for sensing biological signals for fast point-of-care diagnostics or threat detection. One of the solutions is the lab-on-a-chip integrated circuit (IC), which is low cost and high reliability, offering the possibility for label-free detection. In recent years, similar integrated biosensors based on the conventional complementary metal oxide semiconductor (CMOS) technology have been reported. However, post-fabrication processes are essential for all classes of CMOS biochips, requiring biocompatible electrode deposition and circuit encapsulation.In this work, we present an amorphous silicon (a-Si) thin film transistor (TFT) array based sensing approach, which greatly simplifies the fabrication procedures and even decreases the cost of the biosensor. The device contains several identical sensor pixels with amplifiers to boost the sensitivity. Ring oscillator and logic circuits are also integrated to achieve different measurement methodologies, including electro-analytical methods such as amperometric and cyclic voltammetric modes. The system also supports different operational modes. For example, depending on the required detection arrangement, a sample droplet could be placed on the sensing pads or the device could be immersed into the sample solution for real time in-situ measurement. The entire system is designed and fabricated using a low temperature TFT process that is compatible to plastic substrates. No additional processing is required prior to biological measurement. A Cr/Au double layer is used for the biological-electronic interface. The success of the TFT-based system used in this work will open new avenues for flexible label-free or low-cost disposable biosensors.
Sarbanes-Oxley and Public Reporting on Internal Control: Hasty Reaction or Delayed Action?
Authors: Gupta Parveen P. , Weirich Thomas R. , Turner Lynn E. 
Published: February 2013

SYNOPSIS
Since its passage, the Sarbanes-Oxley Act of 2002 has been criticized, and praised, by many on numerous grounds and claims. However, no single provision of this law has come under more attack than Section 404, which mandates public reporting of internal control effectiveness by an issuer's management as well as its independent auditors. Even after 10 years, the opposition to the Section 404 internal control requirements has continued to the point where the U.S. Congress through two separate Acts—the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act, and the 2012 Jump Start Our Business Startups (JOBS) Act—have permanently exempted the non-accelerated SEC filers and the “emerging growth” issuers with revenues of $1 billion or less from Section 404(b) of the Sarbanes-Oxley Act of 2002. Many of those who oppose the Section 404 requirements rest their claim on grounds that the U.S. Congress acted in haste in mandating the public reporting of internal controls by U.S.-listed companies and that the issue was not well thought out or debated. They also contend that the U.S. Congress acted under pressure because of the public outrage over the bankruptcy filings of Enron and WorldCom. To the contrary, this paper shows that the debate over public reporting of internal control by U.S. public companies is more than six decades old, dating back to the McKesson & Robbins fraud. This paper reviews relevant legislative proposals, bills introduced in both the House and the Senate, regulatory efforts by the SEC, and the recommendations of many commissions set up by the private sector to inform the reader how these efforts were the deliberative precursors to what was eventually codified in Section 404 of the Sarbanes-Oxley Act of 2002.
How Does an Initial Expectation Bias Influence Auditors' Application and Performance of Analytical Procedures?
Authors: Pike Byron J. , Curtis Mary B. , Chui Lawrence 
Published: February 2013

ABSTRACT
Prior research demonstrates that knowledge of unaudited balances biases auditors' expectations during analytical procedures. What is less understood is how these biases affect auditors' subsequent investigations and their conclusions about the reasonableness of a particular balance. We employ the selective accessibility model to examine the differences in analytical procedure performance when auditor expectations are formed with versus without knowledge of the client's unaudited financial statement balances. In an experimental setting, we found that auditors with knowledge of unaudited balances favored hypotheses and supporting information indicating that the client's balance was reasonably stated. Auditors who formed expectations without current-year figures were more willing to evaluate competing alternatives, could better identify the most pertinent information, and were significantly more likely to identify a material misstatement using an analytical procedure.

Fracture Resistance of Teeth Restored With All-ceramic Inlays and Onlays: An In Vitro Study
Authors: Saridag S , Sevimay M , Pekkan G 
Published: February 2013

SUMMARY
Fracture resistance of inlays and onlays may be influenced by the quantity of the dental structure removed and the restorative materials used. The purpose of this in vitro study was to evaluate the effects of two different cavity preparation designs and all-ceramic restorative materials on the fracture resistance of the tooth-restoration complex. Fifty mandibular third molar teeth were randomly divided into the following five groups: group 1: intact teeth (control); group 2: inlay preparations, lithium-disilicate glass-ceramic (IPS e.max Press, Ivoclar Vivadent AG, Schaan, Liechtenstein); group 3: inlay preparations, zirconia ceramic (ICE Zirkon, Zirkonzahn SRL, Gais, Italy); group 4: onlay preparations, lithium-disilicate glass-ceramic (IPS e.max Press); and group 5: onlay preparations, zirconia ceramic (ICE Zirkon). The inlay and onlay restorations were adhesively cemented with dual polymerizing resin cement (Variolink II, Ivoclar Vivadent AG). After thermal cycling (5° to 55°C × 5000 cycles), specimens were subjected to a compressive load until fracture at a crosshead speed of 0.5 mm/min. Statistical analyses were performed using one-way analysis of variance and Tukey HSD tests. The fracture strength values were significantly higher in the inlay group (2646.7 ± 360.4) restored with lithium-disilicate glass-ceramic than those of the onlay group (1673.6 ± 677) restored with lithium-disilicate glass-ceramic. The fracture strength values of teeth restored with inlays using zirconia ceramic (2849 ± 328) and onlays with zirconia ceramic (2796.3 ± 337.3) were similar to those of the intact teeth (2905.3 ± 398.8). In the IPS e.max Press groups, as the preparation amount was increased (from inlay to onlay preparation), the fracture resistance was decreased. In the ICE Zirkon ceramic groups, the preparation type did not affect the fracture resistance results.

Published: February 2013

SUMMARY

Introduction
The extension of fiber post cementation often does not seem to influence the fracture resistance of restorations. This study evaluated the effects of cementation depths on the retention of fiber posts submitted to artificial aging.

Methods
One hundred and sixty bovine incisors were selected to assess post retention. Following endodontic treatment, the canals were flared with diamonds burs. Postholes were prepared in lengths of 5 or 10 mm, after which fiber posts were relined with composite resin and luted with RelyX ARC or RelyX Unicem. The samples were then submitted to thermal and/or mechanical cycling before testing their pullout bond strengths. Absence of cycling was used as a control. The results of each cement were submitted to two-way and post hoc Tukey tests (α=0.05).

Results
Independent of the aging protocol, a depth of 10 mm showed higher pullout bond strength than did 5 mm, except for RelyX Unicem without cycling. For RelyX ARC, thermomechanical cycling resulted in lower values than in the absence of cycling. Mechanical cycling alone promoted the highest bond strength when the posts were luted with RelyX Unicem.

Conclusion
The effect of artificial aging on the pullout bond strength is dependent on the type of material and the depth.

Published: February 2013

SUMMARYExamining three bleaching systems, this in vivo clinical trial evaluated the relationship among tooth sensitivity, light activation, and agent concentration, and it correlated dental sensitivity with tooth thickness.Materials and Methods:Eighty-seven volunteer patients were included. Inclusion criteria were the presence of anterior teeth without restorations as well as the absence of a previous bleaching experience and absence of noncarious cervical lesions or dental pain. Exclusion criteria included pregnancy or breastfeeding, a maximum of TF3 hypoplasia, tetracycline-fluorosis stains, malpositioned teeth, orthodontic treatment, periodontal disease, and/or analgesic/anti-inflammatory intake. Patients were randomly assigned to three bleaching groups: Group A (n=25) was treated with 15% H2O2 and nitrogenous-titanium-dioxide and was light activated (Lase Peroxide Lite, DMC, SaoCarlos, Sao Paulo, Brazil); Group B (n=27) was treated with 35% H2O2 and was light activated (Lase Peroxide Sensy, DMC); and Group C (n=35) was treated with 35% H2O2 (White Gold Office, Dentsply, 38West Clark Ave., Milford, USA) without light activation. Tooth sensitivity (TS) was self-reported by the patients using the visual analog scale (VAS) at baseline (TS0), immediately after treatment (TSI), and at seven days after treatment (TS7). In 46 patients, tooth thickness was determined by computed tomography. TS0, TSI, and TS7 were compared between the A and B groups to determine the effect of concentration and between the B and C groups to determine the effect of light using analysis of covariance. The correlation between tooth thickness and TSI was determined by Spearman Rho test (SPSS 15).Results:Eighty-seven patients were evaluated at baseline, and 61 were evaluated at seven days. Separated by groups, tooth sensitivity, expressed as VAS value at the time points TS0, TSI, and TS7, respectively, were as follows: Group A: 13.76 ± 13.53, 24.40 ± 25.24, and 5.94 ± 5.5; Group B: 15.07 ± 18.14, 42.4 ± 31.78, and 8.68 ± 17.99; and Group C: 10.80 ± 14.83, 31.51 ± 29.34, and 7.24 ± 9.2. Group A showed significantly lower tooth sensitivity than group B at TSI (p=0.032). No differences were observed in the tooth sensitivities between groups B and C. No correlation was encountered between tooth thickness and tooth sensitivity immediately after treatment (Rho=−0.088, p=0.563). The median tooth thickness was 2.78 ± 0.21 mm.Conclusions:Increases in the concentration of bleaching agents directly affect tooth sensitivity, and LED/laser activation and tooth thickness are not correlated with tooth sensitivity after dental bleaching.
Experimental Initial Partial Polymerization Method for Fuji II Placement Evaluated for Microleakage With/Without Fuji Coat
Authors: Chen JW , Fletcher B , Roggenkamp CL 
Published: February 2013

SUMMARY

Purpose
This laboratory study evaluated an experimental 1-second initial partial polymerization (IPP) technique using Fuji II LC vs the manufacturer's standard placement (control), both with and without Fuji Coat, relative to microleakage.

Methods
Class V restorative preparations were placed on the buccal and lingual aspects of 30 permanent, caries-free and restoration-free, third molar teeth. Fuji II LC restorations were placed either following manufacturer-specified guidelines or IPP for 1 second prior to contouring and full light curing. Half of the restorations were placed using the IPP experimental technique and half of the teeth were finished using Fuji Coat LC. Following thermocycling, specimens were sectioned and dye penetration was measured. SPSS 16 was used for statistical analysis (p&lt;0.05).

Results
Mean microleakage results: experimental/varnish (0.08 ± 0.15 mm), control/varnish (0.17 ± 0.35 mm), experimental/nonvarnish (0.33 ± 0.33 mm), and control/nonvarnish (0.58 ± 0.47 mm). Univariate analysis of variance demonstrated significantly less microleakage for the experimental technique (p&lt;0.001), use of finishing varnish (p&lt;0.001), and the combination of experimental/varnish (p=0.013).

Conclusions
The initial partial polymerization technique of Fuji II LC placement significantly reduces microleakage. Fuji Coat LC results in further diminished microleakage.

Tonsillectomy is one of the most common surgical procedure performed world wide by the ENT Surgeons.Various methods of tonsillectomy have been practiced over the century aimed at reducing or eliminating intraoperative and postoperative morbidity. Coblation tonsillectomy is a recently introduced surgical technique. Tonsillectomy over blunt dissection tonsillectomy in respect of operative time, intraoperative blood loss, postoperative pain, rate of healing of tonsillar fossa and other postoperative complications. This prospective randomized study was done at Maleka Nursing Home, Bogra and Bangladesh ENT Hospital, Dhaka for 36 months from 1st January 2008 to 31December 2010. 200 children were divided into two groups of equal number. In one group, the tonsillectomy performed by Coblation method and in the other group the tonsillectomy Age ranged from 3-12 years with mean age 5.6 in coblation group and 4-14 years with mean age 7.2 in dissection group. Number of male patients were slightly more than female with male female ratio was 3:2 in coblation group and 3.7:2 in dissection group. Operative time and amount of blood loss is significantly reduced in the coblation group (10-25 min, mean 12 min in coblation group, 18-35 min, mean 25 min in dissection group. Tonsillectomy by using coblation have shown less intraoperative bleeding (5ml-100 ml, mean 15 ml compared with 50-230 ml, mean 65 ml in dissection method).During post operative follow-up on day 8, children of coblation group experienced mild to moderate pain with maximum pain on day 2 and no pain on day 8. On the other hand dissection group experienced moderate to severe pain with maximum pain on day 4 and little or no pain on day 8.Children of coblation group returned to normal diet on day 3 and children of dissection group on day 8.On 8th post operative day, coblation group showed smooth healing without any granulation tissue in tonsillar fossa whereas granulation tissue is observed in dissection group. No major complications were noted in any group except one secondary haemorrhage in dissection group. Coblation tonsillectectomy offers less operative time, minimum blood loss, less post operative pain,early return to normal diet and rapid healing of tonsillar fossa.

Authors: Saha Goutam Kumar , Shirin Shapla 
Published: February 2013

A non-linear equation over linear fuzzy real numbers is called a fuzzy non-linear equation. In Classical Mathematics a non-linear equation can be solved by using different types of numerical methods. In this paper a new approach has been introduced to get approximate solutions with the help of Fixed Point Iteration Algorithm. Graphical representation of the solutions has also been drawn so that anyone can achieve the idea of converging to the root of a fuzzy non-linear equation.

Halluciner dans l'inframince
Authors: Dadoun Roger 
Published: February 2013

Résumé Cinéma et psychanalyse sont abordés et rapprochés à partir de la plus petite ressource possible : les sept minutes du court métrage de Duchamp, Anemic Cinema , soutenus par les regards portés sur des œuvres majeures, le Grand verre et Etant donnés ; l’écran blanc du rêve, hypothèse du psychanalyste Lewin se référant à l’image de l’aplatissement du sein chez le nouveau-né. Des figures insolites telles que « puissance-timide » et « inframince » sont mises en valeur, ouvrant la voie à une pratique politique et morale où psychanalyse et cinéma pourraient œuvrer de conserve sous le signe d’un « orgasme de bataille » (Musil).
Non, la nuit n'est pas si noire !
Authors: Rabant Claude 
Published: February 2013

Résumé Que va chercher l’homme dans la salle obscure ? Qu’y trouve-t-il ? Le cinéma a peu inspiré Freud et Lacan, et pourtant il exerce une attraction considérable sur son spectateur parce que cet art met en jeu, sur un mode qui lui est propre, des éléments que l’homme ne peut cesser de considérer. Ainsi, par le gros plan, il ne nous parle que du visage ou de la chose, comme une porte d’entrée vers l’origynaire . Avec lui, il n’est question que d’amour et de désir impossible, de brume de pluie et de silence, ou encore de gloire, de fureur et de meurtre. D’autre part, qu’est-ce que le cinéma sinon la trace mnésique d’un visible créé par trucage et dont la projection, bien que fugitive, peut être répétée à l’envi ? Un réel où se mêlent indissolublement mémoire et perception.

À travers les époques et les cultures, elle ne cesse de montrer ce qui ne peut se dire des catastrophes de l’histoire. Son investigation, faite de « pensées par images », trouve dans ce film un espace-temps atopique et achronique pour pouvoir se dire.
Le temps disjoint : Histoires de fous

Published: February 2013

Résumé Dans Histoires de fous , Mieke Bal et Michelle Williams Gamaker explorent l’univers de la folie, présentant une vision atypique de la maladie : montrée comme une source alternative de connaissance. Cette « histoire de la folie » particulière introduit un sens anachronique de la temporalité qui met en question la linéarité du récit et montre des modes divers d’expérimenter le temps. Des modes productifs et affectifs qui, de nouveau, ont pour centre la folie. Enfin, le film montre les rapports entre violence, mémoire et folie, et observe les manières qu’a la maladie de servir comme autodéfense face à la menace de la désagrégation du sujet, fonctionnant en même temps comme une blessure et comme une armure.

Des sons de la pensée-ciné
Authors: Klumpen Anna-Helena 
Published: February 2013

Résumé Histoires de fous (2011) utilise des sons autant que des images pour penser la folie. En référence aux « images de pensée » de Benjamin, cet article examine la scène de « la Grande Salle » à partir de l’hypothèse qu’au moyen de l’effet d’écho, sa « pensée sonore » suggère la conception de la folie comme « écho du passé ». Étant un phénomène à la fois sonore et spatial, l’écho charge le hall de l’hôpital psychiatrique d’histoire et le transforme en espace de réflexion.
