Authors: Edwards A. R. 
Published: September 2015

Abstract
The objective of the paper is to compare and contrast the progress made in the implementation of IO in mining and oil and gas. IO or Digital Oilfield (DOF) has been a major performance improvement initiative in the oil and gas sector for over ten years with many examples now in place. IO for mining has seen a slower uptake with relatively few examples over the last five years. This paper will cover IO implementation examples from Mining in Australia and Chile and in Oil and Gas from Australia, Canada and Europe.
This paper will explore the similarities and difference in approach for the implementation of IO in mining and Oil and Gas. Specifically it will discuss:
Common drivers for IO in mining and oil and gas. Similarities between the application of IO Differences in the application of IO Single site versus a value chain approach. Remote control versus an operational support model. Characteristics of a successful implementation in both Mining and Oil and Gas. Key common lessons learned.
The results will be drawn from IO implementations in Iron Ore and Copper mining and from land based LNG and oil sands operations. The following items will be covered:
The use of remote collaboration, operations and engineering support in both mining and oil and gas. The use of remote control in land based operations in both mining and oil and gas. A comparison of the LNG value chain with the Iron Ore value chain. A comparison of the water cycle management in copper mining with the steam management in SAGD operations. Key conclusion on the similarities and difference of IO in mining and oil and gas.
Femtosecond Laser-assisted Wavefront-guided LASIK Using a Newer Generation Aberrometer: 1-Year Results
Authors: Prakash Gaurav , Srivastava Dhruv , Suhail Muhammad 
Published: September 2015

PURPOSE:
To evaluate long-term outcomes of wavefront-guided LASIK with a new advanced aberrometer.

METHODS:
Fifty eyes of 25 LASIK candidates with myopia and/or astigmatism underwent aberrometry (iDesign Advanced WaveScan; Abbott Medical Optics, Santa Ana, CA), femtosecond laser-assisted flap creation, and excimer ablation. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent (SEQ), and astigmatism outcomes were measured at 1, 3, 6, and 12 months postoperatively.

RESULTS:

The sphere, cylinder, and SEQ were −4.29 ± 1.94, −0.75 ± 0.76, and −4.67 ± 2.01 diopters (D), respectively, preoperatively and 0.03 ± 0.13, −0.09 ± 0.13, and −0.02 ± 0.14 D, respectively, 12 months postoperatively (
P
< .001). The postoperative log-MAR CDVA (−0.07 ± 0.09) and UDVA (−0.04 ± 0.09) were better than the preoperative logMAR CDVA (0.07 ± 0.10) (
P
< .01). Ninety-four percent achieved a 12-month logMAR UDVA of 0.0 or less (20/20 or better Snellen) and 100% achieved 0.3 or less (20/40 or better Snellen), compared to a preoperative logMAR CDVA of 0.0 or worse in 54% and 0.3 or less in 100%. Postoperative SEQ was within ±0.50 D in 98%. The regression plot for achieved (y) vs intended (x) correction at 12 months was (y = 0.98 × − 0.09,
R
2
= 0.99,
P
< .001). No cases lost CDVA. The target and 12-month surgically induced astigmatisms (TIA and SIA) were 0.91 ± 0.75 and 0.82 ± 0.70, respectively. The regression plot between them was SIA = 0.91 × TIA − 0.01 (
R
2
= 0.95,
P
< .001). The angle of error was −0.29° ± 12.6° and index of success was 0.13 ± 0.25. There was only a mild, nonsignificant increase of higher-order aberrations after surgery, and the postoperative wavefront was stable on follow-up.

CONCLUSIONS:
Wavefront-guided LASIK with iDesign aberrometry appears to be safe and effective in this long-term, consecutive case series.

Authors: Jia Honggang , Nie Yufeng , Li Junlin 
Published: September 2015

AbstractIn this paper, a method for extracting stress intensity factors (SIFs) in orthotropic thermoelasticity fracture by the extended finite element method (XFEM) and interaction integral method is present. The proposed method is utilized in linear elastic crack problems. The numerical results of the SIFs are presented and compared with those obtained using boundary element method (BEM). The good accordance among these two methods proves the applicability of the proposed approach and conforms its capability of efficiently extracting thermoelasticity fracture parameters in orthotropic material.

Published: September 2015

ABSTRACTEctopic pituitary adenomas are uncommon lesions and are found along the migratory pathway of the Rathke's pouch. Sites reported include suprasellar region, clivus, sphenoid sinus, nasopharynx, third ventricle, petrous temporal bone, hypo thalamus, etc. Compared to intrasellar adenomas, a higher proportion of the ectopic examples are functional and most commonly produce adenocorticotropic hormone (ACTH). The authors report two cases of ectopic pituitary adenoma in the sphenoid sinus in two male patients 36 and 40 years old, presenting with epistaxis. Both the patients did not have any endocrine abnor malities. The clinical and imaging findings were suggestive of sinonasal malignancy. The final diagnosis was made after histopathological examination and immunohistochemistry for cytokeratin, chromogranin and pituitary hormones. The diagnosis of ectopic pituitary adenomas is difficult especially in those tumors that are nonfunctioning. After extensive literature search, we could find only six cases of nonfunctioning adenomas reported in the sphenoid sinus and in all these cases the correct diagnosis could be made only by histopathology.How to cite this articleGovindan A, Sasi P, Radhakrishnan S, Alapatt JP, Aravindan KP.

Abstract

Context: Postoperative ileus is a major complication of abdominal surgical procedures

Objective: To evaluate the incidence of ileus and gastrointestinal morbidity in patients who received immediate postoperative feeding and bowel stimulation after undergoing major gynecologic surgical procedures.

Methods: During a 5-year period, the authors tracked demographic, surgical outcome, and follow-up information for 707 patients who underwent major gynecologic operations. All patients received the same postoperative orders, including immediate feeding of a diet of choice and bowel stimulation with 30 mL of magnesium hydroxide (milk of magnesia) twice daily until bowel movements occurred.

Results: Of 707 patients, 6 (<1%) had postoperative ileus. No patients experienced postoperative bowel obstruction and 2 patients (0.3%) had postoperative intestinal leak. No serious adverse effects associated with bowel stimulation were reported.

Conclusion: Immediate postoperative feeding and bowel stimulation is a safe and effective approach to preventing ileus in patients who undergo major gynecologic surgical procedures.
Enablers That Positively Impact Implementation of Organizational Change
Authors: Cheng Lily 
Published: September 2015

AbstractThis study analyzes the enablers identified by Organization Development (OD) practitioners from interpretivist’s view as being necessary for positive change to happen in organization. Through semi-structured interviews with six OD practitioners from three organizations that elicit their experiences of change initiatives, nine enablers were found that span across the three dimensions of content, context and process suggested in Armenakis and Bedeian’s [1] Integrated Theoretical Framework for change. The research data also indicates that the interdependence of these three change dimensions increases the level of change recipients’ commitment towards successful implementation of change, and suggests that the intangible dimensions of context, as compared to the tangible dimensions of content and process, is found to require more attention from OD practitioners in order for change to be successfully implemented.

Published: September 2015

AbstractIntroductionPeritoneal mesothelioma, a very rare and lethal malignancy, has not been investigated as extensively as pleural mesothelioma, although the role of asbestos exposure in its occurrence is well‐known. Data from Italy are relevant, as it was the largest European asbestos producer, and asbestos was widely used in many economic activities.MethodsA population‐based mortality and incidence analysis was performed in Italy. Data sources were the National Multiple‐causes‐of‐death Database (1995–2010) and the Italian Mesothelioma Register (1993–2008).ResultsWe found an increasing trend of age standardized mortality rates in men, but no clear trend in women; moreover, we showed significant risks of death in several northern regions, formerly heavy asbestos users; finally, mortality/incidence ratios similar for both genders (about 0.8) were estimated.ConclusionsThe study, based on national data, showed a higher risk of mortality from and incidence of peritoneal mesothelioma in areas with formerly heavy exposure to asbestos.

AbstractMethan erhöht als reaktives Gas drastisch die Selektivität der Lichtbogensynthese von M‐Ti‐Carbidclusterfullerenen (M=Y, Nd, Gd, Dy, Er, Lu). Ferner ermöglicht die Optimierung der Prozessparameter die Synthese von Dy2TiC@C80‐I und dessen einfache Isolierung in einem einzigen chromatographischen Schritt. Neben einem zweiten Isomer des M2TiC@C80 wurde außerdem eine neue Clusterart mit endohedraler Acetylidgruppe, M2TiC2@C80, entdeckt. Weiterhin wirken Dy2TiC@C80‐(I,II) und Dy2TiC2@C80‐I als Einzelmolekülmagenten (SMMs), jedoch verschlechtert das zweite Kohlenstoffatom im Cluster des Dy2TiC2@C80 die SMM‐Eigenschaften erheblich.
New fracture characterization in polymer miniature specimens based on the essential work of fracture
Authors: Cuesta Isidoro I. , Alegre Jesus M. 
Published: September 2015

ABSTRACTThe fracture characterization under plane‐stress conditions in polymer sheets in recent decades has usually been done through the application of the essential work of fracture (EWF) method. However, when deeply double‐edged, notched tensile standard specimens cannot be obtained, the use of alternative small pieces, such as prenotched miniature specimens, could be a viable solution. This is why we examined the new fracture characterization in polymer‐prenotched small punch test (SPT) specimens in this study. With the results that we obtained, the feasibility of using prenotched SPT specimens for evaluating the EWF parameters and their correspondence with the results from standard specimens were established. © 2015 Wiley Periodicals, Inc.

Published: September 2015

AbstractBackgroundR0 resection rates (complete tumour removal with negative resection margins) in pancreatic cancer are 70–80 per cent when a 0-mm margin is used, declining to 15–24 per cent with a 1-mm margin. This review evaluated the R0 resection rates according to different margin definitions and techniques.MethodsThree databases (MEDLINE from 1946, PubMed from 1946 and Embase from 1949) were searched to mid-October 2014. The search terms included ‘pancreatectomy OR pancreaticoduodenectomy’ and ‘margin’. A meta-analysis was performed with studies in three groups: group 1, axial slicing technique (minimum 1-mm margin); group 2, other slicing techniques (minimum 1-mm margin); and group 3, studies with minimum 0-mm margin.ResultsThe R0 rates were 29 (95 per cent c.i. 26 to 32) per cent in group 1 (8 studies; 882 patients) and 49 (47 to 52) per cent in group 2 (6 studies; 1568 patients). The combined R0 rate (groups 1 and 2) was 41 (40 to 43) per cent. The R0 rate in group 3 (7 studies; 1926 patients) with a 0-mm margin was 72 (70 to 74) per cent The survival hazard ratios (R1 resection/R0 resection) revealed a reduction in the risk of death of at least 22 per cent in group 1, 12 per cent in group 2 and 23 per cent in group 3 with an R0 compared with an R1 resection. Local recurrence occurred more frequently with an R1 resection in most studies.ConclusionMargin clearance definitions affect R0 resection rates in pancreatic cancer surgery. This review collates individual studies providing an estimate of achievable R0 rates, creating a benchmark for future trials.
Seeking consistency between planning orientation and situational purchase mindset
Authors: Spears Nancy , Amos Clinton , Yazdanparast Atefeh 
Published: September 2015

AbstractThe research applies consistency theory to investigate how planning orientation, planner, or reactor combines with situational purchase mindsets. The results of three studies reveal that (i) consistency between planning orientation and situational mindset fosters more action responses in terms of number of stores one intends to visit or actually visited; (ii) when inconsistency is experienced, action responses are fewer because the consumer seeks to resolve inconsistencies by consulting others to help build consensus toward one emerging purchase decision alternative; (iii) the findings depend upon whether the purchase context is hedonic or utilitarian for the planner but not for the reactor; and (iv) the impulsive scenario reverses the predictions of consistency theory.

Titania Morphology‐Dependent Gold–Titania Interaction, Structure, and Catalytic Performance of Gold/Titania Catalysts
Authors: Chen Shilong , Zhang Bingsen , Su Dangsheng , Huang Weixin 
Published: September 2015

AbstractEmploying anatase TiO2 nanocrystals with predominantly {0 0 1} facets, anatase TiO2 nanocrystals with predominantly {1 0 0} facets, and TiO2 P25 with predominantly {1 0 1} facets as supports, we have comprehensively studied the morphology effect of TiO2 on the Au‐TiO2 interaction, structure, and catalytic performance of Au/TiO2 catalysts in C3H6 epoxidation with H2 and O2, C3H6 oxidation with O2, and H2 oxidation. A strong morphology‐dependent interplay between the Au‐TiO2 interaction and the catalyst structure was observed. Only Au nanoparticles were present in the Au/TiO2 catalysts and the Auδ− species was the largest in Au/TiO2{0 0 1} due to the creation of surface O vacancies of TiO2{0 0 1} upon Au loading, whereas the fraction of Auδ+ species was largest in Au/TiO2{1 0 0} due to the preserved surface stoichiometry of TiO2{1 0 0} upon Au loading. In H2 oxidation, Au/TiO2{1 0 0} with the largest fraction of Auδ+ species was the most active but least selective toward H2O2, whereas Au/TiO2{0 0 1} with the largest fraction of Auδ− species was the most selective toward H2O2. In C3H6 oxidation with O2, tiny C3H6 conversions with the formation of partial oxidation products were observed at low temperatures, whereas C3H6 combustion occurred at high temperatures. In C3H6 epoxidation with O2 and H2, the ensemble consisting of closely connected Auδ− and Ti4+ on anatase TiO2{0 0 1} and {1 0 1} facets with weak adsorption ability was the active structure and the Au/TiO2{0 0 1} catalyst containing the largest amount of this ensemble was the most active. These results demonstrated morphological engineering of oxides as an effective strategy to optimize the catalytic performance and understand the fundamentals of catalysis involving oxides.

Published: September 2015

AbstractThe preparation of surface gradients is a hot topic in contemporary research. Among various physical chemistry approaches, bipolar electrochemistry allows the control of such gradients through the interfacial polarization between a conducting substrate and an electrolyte solution. Here, we report the straightforward, single‐step generation of metal composition gradients on cylindrical carbon fibers. The screening of different metal deposit morphologies, which evolve gradually along a bipolar electrode, is demonstrated with monometallic layers as well as a bimetallic composite layer based on copper and nickel.
Adsorption of Propene on Neutral Gold Clusters in the Gas Phase
Authors: Janssens Ewald , Le Hai Thuy , Lievens Peter 
Published: September 2015

AbstractThe adsorption of propene on neutral gold clusters is investigated in a collision cell under a few collision conditions. The adsorption reaction is studied by pressure‐dependent kinetic measurements and delayed unimolecular dissociation of the excited Aunpropene complexes. The cluster size (n=9–25) and temperature (T=90–300 K) dependence of the propene adsorption is analyzed. Strong size dependences of the absorption reaction are observed; a larger propene adsorption probability was found for gold clusters composed of an even number of atoms. Propene binding energies are estimated by comparison of the temperature‐dependent unimolecular dissociation rates with rates obtained by using statistical RRKM modeling. The Aun–propene binding energies decrease non‐monotonously with cluster size and are in the range of 1.2–0.85 eV for n=9–25. Finally, the bonding of C3H6 on Aun is qualitatively described and similarities with the absorption of CO molecules on gold clusters are discussed.
Conjugated Microporous Poly(Benzochalcogenadiazole)s for Photocatalytic Oxidative Coupling of Amines under Visible Light
Authors: Wang Zi Jun , Garth Kim , Ghasimi Saman , Landfester Katharina , Zhang Kai A. I. 
Published: September 2015

AbstractMetal‐free visible‐light photocatalysts offer a clean, sustainable solution to many pressing environmental issues. Herein, we present a molecular design strategy to fine‐tune the valence and conduction band levels of a series of conjugated microporous polymer networks based on poly(benzochalcogenadiazole) for heterogeneous photocatalysis. Enhanced photocatalytic efficiency was observed by altering the chalcogene moieties in the electron‐accepting benzochalcogenadiazole unit of the polymer backbone structure. Photooxidative coupling of benzylamines was chosen as a model reaction. This design strategy leading to enhanced efficiency could potentially improve a wide range of photoredox reactions.
Efficient and secure certificateless signature scheme in the standard model
Authors: Pang Liaojun , Hu Yufei , Liu Yi , Xu Kedong , Li Huixian 
Published: September 2015

SummaryCertificateless cryptography not only enjoys many advantages of identity‐based cryptography (IBC) but also eliminates the fatal drawback, which is called the key escrow in IBC. Most of the early certificateless signature schemes are secure based on the random oracle model, and nowadays, more and more researchers put emphasis on the scheme based on the standard model. In 2010, Xia et al. demonstrated that the previous schemes in the standard model cannot resist the public‐key‐replace attack. In 2012, for the purpose of overcoming the common drawback, Yu et al. presented a new certificateless signature scheme. However, under the public‐key‐replace attack and malicious‐but‐passive key generation center attack, this scheme is proven to be vulnerable. Moreover, there are too many bilinear pairings used in this scheme, which lead to its low computation efficiency. Aiming at the weakness of the scheme byYu et al., we propose a new certificateless signature scheme, which provides stronger security and higher computational efficiency than the existing schemes. In addition, according to the concept of Girault's trust level, the new scheme can reach trust level 3. Copyright © 2015 John Wiley & Sons, Ltd.
