Published: February 2015

ABSTRACTThe effect of Si addition on microstructure and mechanical properties of dual two-phase intermetallic alloys was investigated. Si was added to the base alloy composition Ni75Al9V13Nb3+ 50 wt. ppm B by three substitution ways in which Si was substituted either for Ni, for Al and for V, respectively. The alloys added with 1 at.% Si showed a dual two-phase microstructure composed of Ni3Al (L12) and Ni3V (D022) phases, while the alloys added with over 2 at.% Si exhibited the same dual two-phase microstructure but contained third phases. The third phases were G phase (Ni16Si7Nb6) and A2 phase (the bcc solid solution consisting of Nb and V). Yield and tensile strength of the 1 at.% Si-added alloys were high in the alloy in which Si was substituted for Al but low in the alloys in which Si was substituted for Ni or for V, in comparison with those of the base alloy. Tensile elongation was lower than that of the base alloy irrespective of substitution ways. The density of the Si added alloys was close to or slightly lower than that of the base alloy. Oxidation resistance of the Si added alloy was increased. Si addition to the dual two-phase intermetallic alloys is beneficial for reducing the density and enhancing the oxidation resistance without a harmful reduction of strength properties.

Published: February 2015

AbstractThe results of our recent neutron scattering studies on actinide ‘115’ compounds are reviewed. The itinerant many-bodyf-electronsystem and cross over to the localized character are realized only in actinide system. Actinide ‘115’ family is very interesting, because we can grow high quality single crystals of many iso-structural compounds with different number and character offelectrons and valencedelectrons. Variety of the ground state have been reported, e.g. paramagnetic, itinerant magnetism, and heavy fermion superconductivity in PuCoGa5. Very recently we have intensively studied the magnetic structure in UTGa5and NpTGa5, These compounds exhibit a variety of the magnetic structure with A-, C-, G-type antiferromagnetic and ferromagnetic ordering and canted structure. NpFeGa5exhibits an unusual magnetic anisotropy with the direction of the magnetic moment inclined about 25 degrees from the tetragonal basal plane. On the other hand, the localized compounds RRhIn5 (R: Tb, Ho, Dy, Nd) shows the antiferromagnetic structure withq=(1/2 0 1/2). The magnetic moment is parallel to the c-axis. An identical magnetic structure in rare earth compounds is a consequence of the localized nature of 4felectrons. We found that NpFeGa5, NpNiGa5, and NpRhGa5exhibit 5felectronic transition between the low- and high-moment states associated with a change in the direction of the magnetic moment. The diverse magnetic ordering and the 5felectronic transition suggest that the orbital degree-of-freedom of itinerant 5felectrons may play important role for the physical properties in many bodyf-electron systems. Actually a localized model predicts the magnetic structure and the phase diagram with magnetic and quarupolar order parameters. A resonant X-ray scattering study is in progress, if the predicted antiferroquadrupole order coexists with the canting antiferromagnetic dipole order in NpNiGa5.

Objective To determine changes in dental anxiety levels of cleft lip and/or palate (CL/P) children and to explore the role of coping strategies in the development of their dental anxiety. Design Prospective study. Setting Free University Medical Center Amsterdam. Patients A sample of CL/P children (at T1: n = 153, 4 to 18 years, 67 girls; at T2: n = 113, 7 to 21 years, 51 girls). Data were available at both time points for 102 children. Measures Dental anxiety and coping strategies were assessed at the start of the study (T1; mean age: 9.8 years, standard deviation 4.1) and 3 years later (T2; mean age: 13.4 years, standard deviation 3.8). These scores were compared to a normative group of Dutch children. Main Outcome Measure(s) The severity of dental anxiety was indexed using the Parental Version of the Dental Subscale of the Children's Fear Survey Schedule. Dental coping strategies were assessed with the Dental Cope Questionnaire. Results Overall, dental anxiety decreased to a level equal to normative scores of Dutch children. However, 5% of the children became more anxious. At T2, children used significantly fewer coping strategies. Children whose level of dental anxiety increased significantly used more destructive coping strategies than children whose level of dental anxiety decreased significantly or remained stable. Conclusions Results suggest that dental anxiety levels of most CL/P children gradually decline over time. Whereas some coping strategies have the potential to be protective, more destructive coping strategies may put children at greater risk for developing and maintaining their dental anxiety.

Authors: Zhu Shiwen , Jayaraman Jayakumar , Khambay Balvinder 
Published: February 2015

Objective To identify whether laypeople and professionals rate the facial appearance of patients with cleft lip and palate (CLP) similarly based on viewing full facial images. Design Several electronic databases were searched. A hand search was performed among reference lists and relevant journals. Studies that assessed the full facial appearance of patients with CLP based on two-dimensional (2D) photographs, 3D images, or clinical examination by laypeople and professionals using a visual analog scale (VAS) or a categorical rating scale were included. Two authors independently assessed articles using methodologic-quality scoring protocol. Result Eleven articles were included in qualitative synthesis, including four high-level and seven moderate-level papers. Three studies found that laypeople were more critical than professionals, three found there was no significant difference between laypeople and professionals, and five reported that professionals were more critical than laypeople when assessing facial appearance of patients with CLP. Conclusions It still remains unknown whether laypeople are more or less critical than professionals when rating facial appearance of patients with repaired CLP. Professionals are more familiar with the esthetic outcomes and difficulties of treating patients. The opposite maybe true for laypeople; this disparity between what is achievable by professionals and what is expected by laypeople may be a source of dissatisfaction in facial appearance outcome. Further well-designed studies should be carried out to address this question and the clinical significance of the difference in rating scores for patients with CLP.

Published: February 2015

Background Growing up with a cleft lip and/or palate presents a number of challenges for those affected and their families. Understanding why some individuals cope well while others struggle is key to psychological research in this field. A better appreciation of the factors and processes that contribute to psychological adjustment to cleft lip and/or palate (CL/P) from the patient perspective would be of value to both researchers and clinicians. Design Qualitative data elicited from individual interviews with 52 adults born with CL/P. Result Inductive thematic analysis identified three main themes: “background” factors (age, gender, sexual orientation, culture, additional conditions, socioeconomic status, and adoption), “external” factors (treatment autonomy, familial coping and support, salience, public understanding, psychological input, and peer support), and “internal” psychological factors (perceptions of difference, noticeability and teasing, social confidence, internalization of beauty ideals, valence, expectations of treatment, responding to challenges, social comparisons, acceptance, faith, dispositional style, and recognition of strengths and positive growth). Conclusions The number and breadth of factors identified in this study are testament to the importance of psychology in the field of CL/P and may offer guidance in relation to developing and assessing the value of psychological interventions. There is a clear role for psychologists in tackling appearance-related concerns, designing materials, supporting patient decision making, and improving social interaction, as well as providing specialist psychological support. The findings illustrate the potential degree of individual variation in perspectives and offer insight into the conflicting results found within current literature.

Published: February 2015

Abstract
Geomechanical models of commercial reservoirs comprise hundreds of thousands to millions of grid cells. These lead to large systems of linear equations. The solution of these systems is time consuming and, in most cases, dominates the total runtime of geomechanical simulations (70 to 80% of the total runtime). In this paper, we will present a solution for accelerating the linear solver by combining a state of the art deflation algorithm with GPU technology to achieve a speed-up of 4 to 5 times for geomechanical simulations. In this paper, we will include details of both the deflation algorithm for geomechanics and our GPU implementation. We will conclude by presenting the numerical results obtained.
Implementation of a Preprocessor for Embedded Discrete Fracture Modeling in an IMPEC Compositional Reservoir Simulator

Published: February 2015

Abstract
The Embedded Discrete Fracture Model (EDFM) is a promising new method used to explicitly model high-level inhomogeneities such as conductive faults or fractures. The EDFM formulation can be used to model naturally fractured reservoirs (NFR) and unconventional reservoirs through also in a triple porosity model composed of hydraulic fractures, natural fractures, and matrix domains for simulation of unconventional reservoirs. Using non-neighboring connections, the EDFM approach was implemented in an IMPEC compositional reservoir simulator (UTCOMP). A preprocessing code was developed to convert the discrete natural/hydraulic fractures into a data set to be used by the simulator, which allows more realistic representation of fractured reservoirs. Compared to previous studies, the developed preprocessing code introduces additional features to better represent structural properties of matrix and fractures, such as implementation of Odas permeability tensor formulation for modeling permeability anisotropy, partial penetration of fractures into the grid, partial intersection of fractures, and calculation of equivalent properties using the definition of density of fractures for conventional dual porosity/dual permeability simulation. The preprocessing code is also capable of handling the data generated by commercial geological modeling softwares. Both the updated UTCOMP and preprocessing code were validated against in-house fully implicit simulator (GPAS) and fine-grid models using commercially available reservoir simulators. Simulation run time was improved by applying a porosity cut-off in the fracture cells, upon which constant fracture conductivity was assumed. Validation case studies include multi-fractured wells producing through depletion and a 2D quarter five-spot production scheme (water and miscible gas injection) in NFR. Moreover, the updated UTCOMP was further used for application case studies including 3D models and considering miscible gas injection for different, geological scenarios: horizontal, dipping, and anticline fractured reservoirs. Both continuous gas and water alternating gas (WAG) injection were evaluated. The validation studies show good agreement between EDFM and fine-grid models. Results show that the effect of fractures on hydrocarbon production depends on fracture network connectivity, which can be properly modeled using the preprocessing code integrates with a numerical simulator capable of handling non-neighboring connections.
Modeling from Reservoir to Export: A Compositional Approach for Integrated Asset Model of Different Gas Fields in North Kuwait Jurassic Carbonate Reservoirs

Published: February 2015

Abstract
A project was undertaken to construct an overview to build an integrated asset model (IAM) of an onshore fractured carbonate gas condensate and volatile oil asset in Northern Kuwait that is considered the first gas asset discovered in Kuwait. The asset has the potential to produce from six distributed fields producing from four hydrocarbon-bearing structures. The development strategy calls for extensive drilling and facilities expansion to increase and sustain production with the potential addition of depletion compression to further sustain the plateau. Because the reservoirs are highly compartmentalized, they are split into 19 separate models. Production is through three surface facilities, fluids vary significantly across the field from sour gas condensate to volatile oil, and it is important to consider the impact of reservoir deliverability, facilities capacity, and surface backpressure when evaluating different development scenarios.
A novel IAM was constructed that integrates reservoirs, wells, pipelines, and facilities models into an integration platform. The IAM comprises 19 black oil dual porosity reservoir models coupled to a compositional network model via black oil delumping to convert the subsurface rates into six-components composition. A split table (compositional delumping) is then used to convert the six-components composition to 35 surface components to be used in the equation-of-state (EOS) surface network models to estimate the composition at each point at the surface (inlet and outlet of each facility). Then the network model is coupled to surface facilities modeling to estimate the rates and composition at the export level. This idea of mapping the subsurface fluid from black oil at subsurface to compositional at surface reduces the subsurface running time and makes the IAM more feasible from the running time perspective.
The IAM has highlighted several differences versus the stand-alone modeling and the coupled modeling at the surface only. First, more accurate accounting for backpressure results in an increase in the plateau. Second, a production forecast for each facility gives a detailed analysis of production and the number of wells for each facility. Finally, detailed compositional information becomes available at all points in the surface network, which is important input to the facilities design.
Direct Simulation Monte Carlo Method in Porous Media with Varying Knudsen Number
Authors: Christou Chariton , Kokou Dadzie S. 
Published: February 2015

Abstract
Shale and tight gas reservoirs consist of porous structures with pore diameter in the range of some mm to μm. At these scales, the pore diameter becomes comparable to the gas mean free path. Flows in these structures fail often in the transition and slip regimes. Standard continuum fluid methods such as the Navier-Stokes-Fourrier set of equations fail to describe flows of these regimes. We present a Direct Simulation Monte Carlo study of a 3D porous structure in an unlimited parallel simulation. The three-dimensional geometry was obtained using a microcomputed–tomography (micro-CT) scanner with a resolution in the scale of some μm. The gas considered is CH4 (100%) and the gas inter-molecular collision model for the simulation is the variable hard sphere (VHS). We present results for different Knudsen numbers. The DSMC is applied in porous structures for the flow regimes where it was found in the cavity case to be appropriate. Our results demonstrate that significant differences appear in gas properties depending on the Knudsen number and the flow regime.

Authors: Nieto Rubén , Boixadós Mercè , Aumatell Eva , Huguet Anna , Hernández Eulàlia 
Published: February 2015

Objective:
Information and communication technologies (ICT) have great potential for health care. In this study
we explore undergraduate psychology students’ perceptions about different specific uses of ICT for health (i.e. online
interventions, health information websites, telehealth and online social networks).

A total of 113 students answered an online survey designed to gather their perceptions about the use of these four types of
interventions for health purposes.

Results:

Results showed that online interventions and telehealth were assessed as the best ways of using ICT for health,
while the worst way was using social networks for health. The most frequently mentioned advantages were related to the
fact that ICT can help with access to information and/or treatments, and that they are comfortable. The most frequently
mentioned disadvantages were related to the quality of the information (for social networks and health information
websites) and the fact that they were considered impersonal (for telehealth and online interventions).

Conclusions:

Students were not very enthusiastic about the use of ICT for health. Education is needed to change these
perceptions and increase the likelihood that they will incorporate ICT in their future practice.

Authors: Saari Jukka M 
Published: February 2015

Purpose
To study the population-based annual incidence rates of exudative, dry and all cases of symptomatic age-related macular degeneration (AMD) in different age and sex groups.

Methods.
This is a one year, prospective, population-based study on all consecutive new patients with AMD in the hospital district of Central Finland. The diagnosis was confirmed in all patients with slit lamp biomicroscopy, optical coherence tomography (OCT) using a Spectralis HRA + OCT device, and the Heidelberg Eye Explorer 1.6.2.0 program. Fluorescein angiograms were taken when needed.

Results.
The population-based annual incidence rates of all cases of symptomatic AMD increased from 0.03% (95% CI, 0.01-0.05%) in the age group 50-59 years to 0.82% (95% CI, 0.55-1.09%) in the age group 85-89 years and were 0.2% (95% CI, 0.17-0.24%) in exudative, 0.11% (95% CI, 0.09-0.14%) in dry, and 0.32% (95% CI, 0.28-0.36%) in all cases of AMD in the age group 60 years and older. During the next 20 years in Central Finland the population-based annual incidence rates can be estimated to increase to 0.27% (95% CI, 0.24-0.30%) in exudative, to 0.13% (95% CI, 0.11-0.15%) in dry, and to 0.41% (95% CI, 0.37-0.45%) in all cases of AMD in the age group 60 years and older. The population-based annual incidence of AMD did not show statistically significant differences between males and females (p>0.1).

Conclusion:
The population-based age-group specific annual incidence rates of symptomatic AMD of this study may help to plan health care provision for patients of AMD.

Authors: Butwicka Agnieszka , Frisén Louise , Almqvist Catarina , Zethelius Björn , Lichtenstein Paul 
Published: February 2015

OBJECTIVE
To assess the risk of psychiatric disorders and suicide attempts in children with type 1 diabetes and their healthy siblings.

RESEARCH DESIGN AND METHODS
We performed a population-based case-cohort study of individuals born in Sweden between 1973 and 2009. Children with type 1 diabetes (n = 17,122) and their healthy siblings (n = 18,847) were identified and followed until their 18th birthday. Their risk of psychiatric disorders was compared with that of matched control subjects.

RESULTS
The risk of psychiatric morbidity in children with type 1 diabetes compared with the general population was tripled within 6 months after the onset of diabetes (hazard ratio [HR] 3.0 [95% CI 2.7–3.4]) and doubled within the total observation period (HR 2.1 [95% CI 2.0–2.2]). An increased risk was noted in suicide attempts (HR 1.7 [95% CI 1.4–2.0]) and in most categories of psychiatric disorders. The risk of psychiatric disorders in probands declined from HR 2.7 (95% CI 2.2–3.3) for those in the cohort born 1973–1986 to 1.9 (95% CI 1.8–2.0) in those born 1997–2009. The risk for any psychiatric disorders among siblings of patients with type 1 diabetes was estimated to be HR 1.1 (95% CI 1.0–1.1), and there was no increased risk in any of the specific category of disorders.

CONCLUSIONS
Children with type 1 diabetes are at high risk of psychiatric disorders, which seems to be a consequence of the disease rather than due to a common familial etiology. The results support recommendations on comprehensive mental health surveillance in children with type 1 diabetes, especially in recently diagnosed children.
