Abstract:
Treacher Collins syndrome (TCS) or Franceschetti syndrome is an autosomal dominant disorder of craniofacial development with variable expressivity. It is named after Edward Treacher Collins (1862-1932), the English surgeon and ophthalmologist, who described the essential components of the condition in 1900. Incidence of this syndrome is approximately 1 in 50,000 live births and it affects both genders equally. The typical physical features include downward slanting eyes, micrognathia (a small lower jaw), Conducting hearing loss, under developed zygoma, drooping part of lateral lower eyelids, and malformed or absent ears. This article describes clinical and radiological features of TCS in a 07 yr old female child who had reported to the department of Dentistry and Radiology with the complaint of forwardly placed upper anterior teeth and hearing loss. Also pathogenesis, prenatal diagnosis, differential diagnosis, management and preventive aspects are discussed.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21074

Abstract:
The integration of disabled children into regular schools is a current educational and social issue causing widespread interest, concern and debate throughout Australia. The most controversial and innovative adoption of integration policy has occurred in Victoria since the release of the Collins Report in 1984. The present study was conducted in 26 State primary schools in the Bendigo area of the Loddon Campaspe Mallee region of Victoria where disabled children had been integrated in regular classrooms with the assistance of a paid teacher aide during 1988. The purpose of the study was to survey the concerns of those teachers into whose classes children with disabilities had been integrated. The Stages of Concern (SoC) dimension of the Concerns-Based Adoption Model (C-BAM) was chosen as the research methodology. C-BAM was developed at the Research and Development Center for Teacher Education, University of Texas at Austin, and for the purpose of this study, the methodology consisted of a questionnaire of 35 standardized items (the Stages of Concern Questionnaire), and a School Survey. The study set out to identify the concerns of teachers (ii) toward integration, and to establish reasons why teachers are at particular stages of concern. Factors included teachers' age, gender, number of years of teaching experience, qualifications and in-service training. Other issues related to the disabled children themselves, the school, and factors such as availability of resources, funding levels, and access to support systems. This study developed from the policy document Integration in Victorian Education (the Collins Report, 1984). Since then, the Ministry of Education has published two additional booklets (in January and February, 1987), which partly address some of the issues included in this thesis. These include resourcing, in-servicing and the legal implications of the innovation. The analysis of the data points to major shortcomings which will jeopardize the implementation process and the likely success of the innovation. A number of recommendations have been suggested, with particular reference to the pre-service and in-service training of teachers, and issues relating to funding and resources. The findings have implications for all classroom teachers, as potentially all are required to accept disabled children into their classes. The results and recommendations also have relevance for the Ministry of Education, whose responsibility it is to ensure that the integration of disabled children into regular classes is fully supported at a government level, and for training institutions, whose task it is to provide appropriate pre-service and in-service programs for present and future classroom teachers.

Abstract:
Phylogenetic trees capture the relationships between species and can be investigated by morphological and/or molecular data. When focusing on macroevolution, one considers the large-scale history of life with evolutionary changes affecting a single species of the entire clade leading to the enormous diversity of species obtained today. One major problem of biology is the explanation of this biodiversity. Therefore, one may ask which kind of macroevolutionary processes have given rise to observable tree shapes or patterns of species distribution which refers to the appearance of branching orders and time periods. Thus, with an increasing number of known species in the context of phylogenetic studies, testing hypotheses about evolution by analyzing the tree shape of the resulting phylogenetic trees became matter of particular interest. The attention of using those reconstructed phylogenies for studying evolutionary processes increased during the last decades. Many paleontologists (Raup et al., 1973; Gould et al., 1977; Gilinsky and Good, 1989; Nee, 2004) tried to describe such patterns of macroevolution by using models for growing trees. Those models describe stochastic processes to generate phylogenetic trees. Yule (1925) was the first who introduced such a model, the Equal Rate Markov (ERM) model, in the context of biological branching based on a continuous-time, uneven branching process. In the last decades, further dynamical models were proposed (Yule, 1925; Aldous, 1996; Nee, 2006; Rosen, 1978; Ford, 2005; Hernández-García et al., 2010) to address the investigation of tree shapes and hence, capture the rules of macroevolutionary forces. A common model, is the Aldous\\\' Branching (AB) model, which is known for generating trees with a similar structure of \\\"real\\\" trees. To infer those macroevolutionary forces structures, estimated trees are analyzed and compared to simulated trees generated by models. There are a few drawbacks on recent models such as a missing biological motivation or the generated tree shape does not fit well to one observed in empirical trees. The central aim of this thesis is the development and study of new biologically motivated approaches which might help to better understand or even discover biological forces which lead to the huge diversity of organisms. The first approach, called age model, can be defined as a stochastic procedure which describes the growth of binary trees by an iterative stochastic attachment of leaves, similar to the ERM model. At difference with the latter, the branching rate at each clade is no longer constant, but decreasing in time, i.e., with the age. Thus, species involved in recent speciation events have a tendency to speciate again. The second introduced model, is a branching process which mimics the evolution of species driven by innovations. The process involves a separation of time scales. Rare innovation events trigger rapid cascades of diversification where a feature combines with previously existing features. The model is called innovation model. Three data sets of estimated phylogenetic trees are used to analyze and compare the produced tree shape of the new growth models. A tree shape statistic considering a variety of imbalance measurements is performed. Results show that simulated trees of both growth models fit well to the tree shape observed in real trees. In a further study, a likelihood analysis is performed in order to rank models with respect to their ability to explain observed tree shapes. Results show that the likelihoods of the age model and the AB model are clearly correlated under the trees in the databases when considering small and medium-sized trees with up to 19 leaves. For a data set, representing of phylogenetic trees of protein families, the age model outperforms the AB model. But for another data set, representing phylogenetic trees of species, the AB model performs slightly better. To support this observation a further analysis using larger trees is necessary. But an exact computation of likelihoods for large trees implies a huge computational effort. Therefore, an efficient method for likelihood estimation is proposed and compared to the estimation using a naive sampling strategy. Nevertheless, both models describe the tree generation process in a way which is easy to interpret biologically. Another interesting field of research in biology is the coevolution between species. This is the interaction of species across groups such that the evolution of a species from one group can be triggered by a species from another group. Most prominent examples are systems of host species and their associated parasites. One problem is the reconciliation of the common history of both groups of species and to predict the associations between ancestral hosts and their parasites. To solve this problem some algorithmic methods have been developed in recent years. But only a few host parasite systems have been analyzed in sufficient detail which makes an evaluation of these methods complex. Within the scope of coevolution, the proposed age model is applied to the generation of cophylogenies to evaluate such host parasite reconciliation methods. The presented age model as well as the innovation model produce tree shapes which are similar to obtained tree structures of estimated trees. Both models describe an evolutionary dynamics and might provide a further opportunity to infer macroevolutionary processes which lead to the biodiversity which can be obtained today. Furthermore with the application of the age model in the context of coevolution by generating a useful benchmark set of cophylogenies is a first step towards systematic studies on evaluating reconciliation methods.

Abstract:
La quinua es un grano con alto valor proteico, vitaminas y aminoácidos, recientemente popularizado en mercados internacionales sobre todo por sus propiedades, beneficios y usos en la cocina; el presente estudio tuvo como objetivo evaluar el efecto de la germinación en la capacidad antioxidante de tres variedades de quinua: Blanca (Salcedo INIA), roja (INIA-415 Pasankalla) y negra (INIA 420-Negra Collana) en la formulación y elaboración de una bebida. Se utilizó un diseño de mezcla obteniendo 10 tratamientos con niveles codificados de 0-3 para las variables independientes (quinua blanca germinada, quinua roja germinada y quinua negra germinada). El modelo propuesto constó de 3 componentes y 10 tratamientos que tuvieron como factor respuesta a la capacidad antioxidante y la aceptabilidad de los consumidores. Los 10 tratamientos fueron sometidos a una prueba de aceptabilidad sensorial a 60 panelistas no entrenados usando el diseño de bloques incompletos. Se midió la capacidad antioxidante a cada tratamiento usando el método ABTS obteniendo 15.91 y 21.60 uM ET/ml para el tratamiento con menor y mayor capacidad antioxidante respectivamente. Los 10 tratamientos fueron comparados con 10 tratamientos realizados con quinua sin germinar en las mismas condiciones; los resultados finales de aceptabilidad y capacidad antioxidante fueron ingresados al programa de diseño de mezcla obteniendo como tratamiento óptimo a la formulación cuya composición consistió de 81,67% de quinua negra germinada y 18,33% de quinua blanca germinada; adicionalmente se realizó el análisis proximal del tratamiento optimizado obteniendo una bebida de quinua germinada con 67.44 calorías por una porción de 200g y con 1.93% de proteínas por cada 100g de bebida. La bebida de quinua elaborada a partir de tres variedades de quinua germinada representa una alternativa novedosa a los actuales productos bebibles que se comercializan en el Perú, por su contenido en antioxidantes y la fácil preparación.

Abstract:
This paper presents a homogeneous system of magnetic colloidal particles that self-assembles via two structural patterns of different symmetry. Based on a qualitative comparison between a real magnetic particles system, analytical calculations and molecular dynamics simulations, it is shown that bistability can be achieved by a proper tailoring of an anisotropic magnetization distribution inside the particles. The presented bistability opens new possibilities to form two-dimensionally extended and flexible structures where the connectivity between the particles can be changed in vivo

Abstract:
This thesis traces the shift from liberal to neoliberal education from the nineteenth century to the present day, in order to provide a rich and previously underdeveloped narrative of value in higher education in England. Rather than attempting to justify the value of the humanities within the presiding economic frameworks, or writing a defence against market rationalism, this thesis offers an original contribution through an immersion in historical, financial, and critical debates concerning educational policy. Drawing upon close reading and discursive analysis, this thesis constructs a nuanced map of the intersections of value in the humanities. The discussion encompasses an exploration of policymaking practices, scientific discourse, mediated representations, and public cultural life. The structure of the thesis is as follows. The introductory chapter outlines the overarching methodology by defining the contemporary period of this project (2008-14), establishing relevant scholarship, and drawing out the correspondences between the nineteenth century and the present day. Chapter one establishes a history of the Payment by Results approach in policymaking, first established in the Revised Code of Education (1862) and recently re-introduced in the reforms of the Browne Report (2010). Understanding the predominance of such short-term and quantitative policy is essential for detailing how value is articulated. Chapter two reconsiders the two cultures debate. In contrast to the misrepresentative, yet pervasive, perception that the sciences and the humanities are fundamentally in opposition, I propose a more nuanced history of these disciplines. Chapter three addresses fictional representations of the humanities within literature in order to establish a vantage point from which to assess alternative routes for valuation beyond economic narratives. The final chapter scrutinises the rise of the impact criterion within research assessment and places it within a wider context of market-led cultural policy (1980-90s). This thesis argues that reflecting on Victorian legacies of economism and public accountability enables us to reconsider contemporary valuation culture in higher education. This analytical framework is of benefit to future academic studies interested in the marketisation and valuation of culture, alongside literary studies that focus on the relationship between higher education, the individual, and the state.

Abstract:
Particle dispersions provide a promising tool for the engineering of functional materials that exploit self-assembly of complex structures. Dispersion made from magnetic colloidal particles is a great choice; they are biocompatible and remotely controllable among many other advantages. However, their dominating dipolar interaction typically limits structural complexity to linear arrangements. This paper shows how a magnetostatic equilibrium state with noncollinear arrangement of the magnetic moments, as reported for ferromagnetic Janus particles, enables the controlled self-organization of diverse structures in two dimensions via constant and low-frequency external magnetic fields. Branched clusters of staggered chains, compact clusters, linear chains, and dispersed single particles can be formed and interconverted reversibly in a controlled way. The structural diversity is a consequence of both the inhomogeneity and the spatial extension of the magnetization distribution inside the particles. We draw this conclusion from calculations based on a model of spheres with multiple shifted dipoles. The results demonstrate that fundamentally new possibilities for responsive magnetic materials can arise from interactions between particles with a spatially extended, anisotropic magnetization distribution.

Abstract:
Understanding the psychosocial classroom environment has been important in both traditional face-to-face courses and online education. Trickett and Moos (1974) pioneered the use of post-course self-report instruments to measure the classroom environment through the Classroom Environment Scale. More recently, Taylor and Maor (2000) developed the Constructivist On-Line Learning Environment Survey (COLLES) to examine the students’ perceptions of online learning environment in light of social constructivist pedagogical principles. The 24-item, Likert-type COLLES instrument is a popular measure for examining online learning environments for a least two reasons. First, it measures the online learning environment along constructivist categories, which makes it in line with the dominant pedagogical philosophy for online instruction. Second, the COLLES instrument is freely included in the Survey Module of Moodle, the most popular open source course management system available. This makes it particularly convenient for online instructors to use COLLES in their teaching and research.

Abstract:
This introductory chapter recounts how E. B. White's essay titled “Mr. Forbush's Friends” opened a new bird world to the author. The essay introduced the author to Edward Howe Forbush, who is best known for writing Birds of Massachusetts and Other New England States, a three-volume set published in 1928. Within the pages of Forbush's work, the author found the expected information — breeding and feeding, size and color — and a bit of the unexpected in his reports on the “Economic Status” of each bird. In this section, he offers how the birds are perceived in the human economy, like the Black-crowned Night Heron, which “is accused of being injurious to the fishery interests.” Forbush was an inspiration for this collection of reports from the field, which expand with reflections on love, family, life, and death and engage a range of emotions from wonder to humor. And because birds magnify our relationship to the natural world, this collection include stories about habitat loss, declining species, birds that collide with buildings, or birds now extinct.

Abstract:
Chapter 1 describes the evolution of British general practice between the 1940s and the 1980s, a period during which it took on a role as the ‘cornerstone’ of the NHS. In the years that immediately followed the inception of the NHS in 1948, the field’s status was low and the Collings report of 1950 offered a damning assessment of the care it offered. Gradually however, policy makers placed an increasing focus on the provision of care in community settings rather than the more costly environment of hospitals. In parallel, general practice went through a process of professionalisation and was recognised as a medical specialty. The combined effect of these developments was to consolidate the position of primary care at the heart of the British healthcare system. General practice nevertheless remained a fragmented field, with practitioners enjoying a great deal of professional autonomy. South Asian migrant doctors were key to these developments. General practice remained unpopular with British-trained doctors, so the presence of migrant doctors masked a recruitment crisis which was particularly acute in industrial areas. The fragmented nature of general practice also resulted in them having a significant impact on the nature of care on a day-to-day basis.

Abstract:
The 1953 discovery of the DNA double-helical structure by James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin, represented one of the most significant advances in the biomedical world (Watson and Crick 1953; Maddox 2003). Almost half a century after this landmark event, in February 2001, the initial draft sequences of the human genome were published (Lander et al., 2001; Venter et al., 2001) and, in April 2003, the International Human Genome Sequencing Consortium reported the completion of the Human Genome Project, a massive international collaborative endeavor that started in 1990 and is thought to represent the most ambitious undertaking in the history of biology (Collins et al., 2003; Thangadurai, 2004; National Human Genome Research Institute). The Human Genome Project provided a plethora of genetic and genomic information that significantly changed our perspectives on biomedical and social sciences. The sequencing of the first human genome was a 13-year, 2.7-billion-dollar effort that relied on the automated Sanger (dideoxy or chain termination) method, which was developed in 1977, around the same time as the Maxam-Gilbert (chemical) sequencing, and subsequently became the most frequently used approach for several decades (Sanger et al., 1975; Maxam & Gilbert, 1977; Sanger et al., 1977). The new generations of DNA sequencing technologies, known as next-generation (second generation) and next-next-generation (third generation) sequencing, which started to be commercialized in 2005, enabled the cost-effective sequencing of large chromosomal regions during progressively shorter time frames, and opened the possibility for new applications, such as the sequencing of single-cell genomes (Service, 2006; Blow, 2008; Morozova and Marra, 2008; Metzker, 2010).

Masato Matsugi of Meijo University showed (J. Org. Chem. 2010, 75, 7905) that over five iterations, the fluorous-tagged Ru catalyst 1b was readily recovered and reused for the cyclization of 2 to 3. Hengquan Yang of Shanxi University reported (Chem. Commun. 2010, 46, 8659) that the Hoveyda catalyst 1a encapsulated in mesoporous SBA-1 could also be reused several times. Jean-Marie Basset of KAUST Catalysis Center, Régis M. Gauvin of Université Lille, and Mostafa Taoufik of Université Lyon 1 described (Chem.

Karol Grela of the Polish Academy of Sciences showed (Synlett 2010, 2931) that 3-nitropropene (not illustrated) participated in cross-metathesis when catalyst 1c was used. Shawn K.

Abstract:
Although photocatalytic chemistry has been the subject of intense interest recently, the rate of these reactions is often slow due to the limited penetration of light into typical reaction media. Peter H. Seeberger at the Max-Planck Institute for Colloids and Surfaces in Potsdam and the Free University of Berlin showed (Chem. Sci. 2012, 3, 1612) that Ru(bpy)32+-catalyzed reactions such as the reduction of azide 1 to 2 can be achieved in as little as 1 min residence time using continuous flow, as opposed to the 2 h batch reaction time previously reported. The benefits of flow on a number of strategic photocatalytic reactions, including the coupling of 3 and 4 to produce 5, was also demonstrated (Angew. Chem. Int. Ed. 2012, 51, 4144) by Corey R.J. Stephenson at Boston University and Timothy F. Jamison at MIT. In this case, a reaction throughput of 0.914 mmol/h compares favorably with 0.327 mmol/h for the batch reaction. Professor Seeberger has also reported (Angew. Chem. Int. Ed. 2012, 51, 1706) a continuous-flow synthesis of Artemisinin 7, a highly effective antimalarial drug, starting from dihydroartemisinic acid 6. The conversion occurs by a sequence of photochemical oxidation with singlet oxygen, acidic Hock cleavage of the O–O bond, and oxidation with triplet oxygen, a process calculated to be capable of furnishing up to 200 g/day per reactor. A scalable intramolecular [2 + 2] photocycloaddition of 8 to produce 9 was reported (Tetrahedron Lett. 2012, 53, 1363) by Matthias Nettekoven of Hoffmann-La Roche in Basel, Switzerland. Stephen L. Buchwald at MIT developed (Angew. Chem. Int. Ed. 2012, 51, 5355) a flow process for the enantioselective β-arylation of ketones that involved lithiation of aryl bromide 10, borylation, and rhodium-catalyzed conjugate addition to cycloheptenone. For continuous flow production of enantioenriched alcohols such as 14, Miquel A. Pericás of the Institute of Chemical Research of Catalonia developed (Org. Lett. 2012, 14, 1816) the robust polystyrene-supported aminoalcohol 13 for diethylzinc addition to aldehydes. Professor Jamison found (Org. Lett. 2012, 14, 568) that flow chemistry provides a convenient and reliable solution to the reduction of esters to aldehydes with DIBALH (e.g., 15 to 16) that occurs rapidly and without the usual problem of overreduction.

Abstract:
This paper aims to analyse the use of evaluative adjectival lexicogrammatical patterns in selected British online newspaper discourse in terms of genre specification. It focuses both on the normalised frequency of the patterns as well as on the evaluative semantic groups of the adjectives embedded in the patterns analysed. The genres chosen for the analysis are politics and crime. 282 articles from six national British online newspapers (the Sun, the Mirror, the Express, the Guardian, the Telegraph, and the Independent) were downloaded to create the corpus. These were then analysed via Sketch Engine for the evaluative adjectival patterns introduced by Bednarek (2009). The adjectives found in the patterns were further examined and manually divided into semantic groups introduced by Collins COBUILD. The data were then compared in an attempt to identify discourse patterns and contrasts, and valuable insights were gained into the lexicogrammatical features studied. The analysis indicated that evaluative adjectival patterns are indeed embedded in newspaper stories and both the tabloids and the broadsheets employ these patterns more or less equally for the same genres. Both types of newspaper mainly embed patterns ‘v-link ADJ’ and ‘v-link ADJ prep’ in both genres. However, when broadsheets report on politics, the use of the 'it v-link ADJ finite/non-finite' pattern, can be considered marked.

Abstract:
Technical Innovation covers the process of creating a new successful competitive product from invention to production and market introduction within a practical company related context. Typically education for this kind of complicated, open ended work requires mastering a wide range of knowledge-areas and a lot of hands-on training practice in projects and workshops. The combination of depth and width is symbolized by the “T-shape”. Well-known learning theories give a good rationale of the teaching approaches that were developed over the years and a confirmation of this approach, including the important role of the experienced tutor, is found in the study of excellent companies. Work of a “T-shaped” engineer in the technical innovation process bears many similarities to the ideal transformation process of a company, like Collins describes in his “Good to Great”. The processes have a very comparable open-ended character, a focus for essence and simple, elegant solutions, opportunities and inventions. Success seems to rely more on the right people and a concentrated shared-goal driven cooperation (“flow”), than on the right methods of work. Collins’ observations and conclusions, applied to the domain of engineering design education helps understanding the earlier reported 15 years success of the International Product Design Engineering (IPDE) course of the Hanze University Groningen, with its combination of lecturing, projects and workshops, with a high reality content and direct supervision. The IPDE-related “Open Dynamic Design” (ODD) project and the educational experiments showed similar observations. Essential is the committed experienced participation in real innovation projects and intensive workshops, lead by very experienced T-shaped supervisors/“masters”, having deep knowledge over a good part of technologies, entrepreneurial and/or design related issues and good understanding of interrelationship and consequences in the other fields. They also should have a track record on the methodologies of product innovation and product development. Like the Collins level-5 leaders, they should be able to be both creative and analytical, give the students freedom and control them at the appropriate moments. They power the theoretical most effective learning “circle” with focused introductions and assignments, their direct, knowledgeable and adequate feedback, and quiet help during contemplation. Then the workshops are really fun and effective. The Loughborough and Glasgow Design engineering courses, the new master course at the Innovation Centre of the University of Technology of Compiegne (UTC) and the one at the Hanze Institute for Technology — an upgrade from IPDE — are built on these insights. To safeguard the continuation of this approach, a pool of experienced and potential (home and guest) T-experts is founded together by the small group of universities and their industrial partners, working jointly in the workshops, projects and modules, training the trainers while training the students - in T-design.

Abstract:
Through the life-time of a production field in the offshore petroleum industry it is normal to drill several new wells for both production and injection purposes. The initial well template, either at the platform or at a subsea installation, has space for a fixed total number of wells. When this limit is reached an old well needs to be plugged and the well slot reused to allow new wells to be drilled. In order to re-use well slots and benefit from full diameter when constructing the new well, it is required to remove the tubulars in the upper part of the plugged well. The outside of these tubulars are normally in contact with cement or settled particles from shut-in drilling fluids. Removing the tubular through the cement or settled particle is always challenging and there is need for using new techniques. In order to address the dominating effects in these operations, down-scaled laboratory tests are performed. The experiments reported here are performed by pulling steel pipes out of a cemented annulus. The pipes used in the tests are down-scaled from typical casing sizes. They are either normal pipes, grooved pipes or pipes with and without collars. Two setups with different geometries are used. The first is selected to study the de-bonding effect from the cemented annulus and the mechanical friction that must be overcome to remove the pipe. The other setup is designed to show the effect of collars when pulling out the tubulars. Since most tubulars in wells have collars between each stand with extended diameter, this effect is important to consider when comparing laboratory results to field operations. Results show that the loosening force (de-bonding) and pulling force can be significantly reduced by manipulating the pipes with grooves prior to pulling them out. Further, the results show that the most significant resistance when pulling the tubulars are caused by the collars outside the pipe. It is also observed that the effect of collar is significantly reduced when the pipe is grooved between the collars. In total these results provide improved understanding on the dominating effects when pulling pipes from packed wellbore annulus.

Abstract:
Abstract To enable real-time monitoring of the physical condition of the drilling equipment such as drill collars, a methodology for efficiently predicting the fatigue life of ports subjected to variable-amplitude cyclic bending or torsional loads is needed. In this paper, such a method is reported, which involves several steps. Firstly, elastic finite element analysis (FEA) of a collar port was performed to determine the elastic stress states with unit loads. Secondly, the unit load-based linear elastic solutions with the loading history were superimposed to produce a time history of the stress tensor. Thirdly, the previously established pseudo-elastic stress states were transformed into the true elastoplastic stress and strain states with a cyclic plasticity model and a notch correction rule. Finally, the cumulative fatigue damage was computed with the rainflow counting algorithm and a damage accumulation rule. The resulting fatigue life predictions for the ports were found to agree favorably with the experimental measurements from full-scale fatigue tests of port-containing collar samples with variable-amplitude loads. This newly developed method can be used to predict the remaining useful life of a port in real time with the loads resulting from downhole measurements or a drill string dynamics simulation code.

Abstract:
A wide range of platform concepts have been investigated for a floating wind turbine. So far analysis and design of motion characteristics of the platform is main research concern. One key research area less focused is floating platform related risk. If the wind energy would be one of the major sources of electric power supply, wind farms which are comprised of large number of floating wind turbines must be deployed in the ocean. Wind turbines are relatively closely arranged in a wind farm. In such an arrangement, a wind turbine accidentally started drifting will have some possibility to collide with floater and moorings of neighboring moored floating wind turbines, and might initiate another drift which might cause progressive drifting of wind turbines. In the previous report, a scenario of progressive drifting of wind turbines was investigated and associated risk was formulated. Quantitative risk of several arrangements of wind farm was estimated. Effects of arrangement of wind turbines in a wind farm and safety factor used in the design of moorings is discussed. Probability of initial drift was evaluated analyzing past records of accidents and design of mooring. In this research, strength of mooring system was modeled more precisely and probabilistic model was developed considering aged deterioration. Risk of progressive drifting was evaluated and safety factor required to realize a acceptable risk of a wind farm was discussed.

Abstract:
The continued shift of exploration and production to deep water fields will require the industry to develop alternative pipe solutions to cope with the challenging demands of these exploration regions. Because of the complexity of exploration conditions in deep water fields, e.g. high pressures, low temperature and sour reservoirs, higher grades and heavier wall thickness in combination with low temperature toughness and suitability for sour service are required. The Vallourec&Mannesmann Tubes’s alloying concept for line pipe steels based on low carbon concept [1] was extended to grades X70 and X80 with wall thicknesses up to 75mm. In this paper the latest results on industrial studies on high strength heavy-wall steels manufactured by seamless hot rolling and subsequent quench and temper treatment are presented. The work is a part of the development program for high performance heavy wall seamless pipes for special applications such as J-lay collars, buckle arrestors and risers. Mechanical properties, advanced metallographic examinations, results of the sour service resistance and weldability are reported.

Abstract:
Abstract Wells are essential in oil and gas production and construction of them is one of the main cost drivers for field development. It is normally needed to drill and construct new wells from existing fields during most of the production time. In order to reduce costs one can re-use parts of existing wells when they are no longer efficient. This is done in offshore fields also when there is limitation for new wells due to capacity of the subsea template. Through tubing drilling is a method to drill a side track through the wellbore tubulars. However, this will normally result in a smaller and less effective well completion. Removing parts of the casing section and drill a larger size sidetrack is an option to provide a new full-size wellbore. Removing the 9 5/8” casing through the settled particle in the annulus can be challenging. The wellbore annulus is normally filled with old drilling fluid, displacing fluid and/or cement slurry. The solid particles of these annular fluids are settled during years of shut-in and make it difficult to move the casing sections. There are several techniques for pulling the casing section, but there is a lack of knowledge of some of the key mechanism causing the resistance in these operations. In order to study and address the dominating effects in these operations, down-scaled laboratory tests are performed. The experiments reported here are performed by pulling steel pipes through the settled barite in the annulus. The pipes used in the tests are down-scaled from typical casing sizes with and without collars. The barite slurry compacted inside the annulus have different hydrostatic and pore pressures. When the pipe is pulled the required mechanical force is measured. Results show that the single most significant factor causing resistance when pulling the tubulars is the collars outside the pipe. Furthermore, it is identified that the pore pressure improves the mobility of the settled particle around the collar. In total these results provide improved understanding on the dominating factors during pulling pipes from a packed annulus.

Abstract:
The process of particle-wall collisions is very important in understanding and determining the fluid-particle behavior, especially near walls. Detailed information on particle-wall collisions can provide insight on the formulation of appropriate boundary conditions of the particulate phases in two-fluid models. We have developed a three-dimensional Resolved Discrete Particle Method (RDPM) that is capable of meaningfully handling particle-wall collisions in a viscous fluid. This numerical method makes use of a Finite-Difference method in combination with the Immersed Boundary (IB) method for treating the particulate phase. A regular Eulerian grid is used to solve the modified momentum equations in the entire flow region. In the region that is occupied by the solid particles, a second particle-based Lagrangian grid is used, and a force density function is introduced to represent the momentum interactions between particle and fluid. We have used this numerical method to study both the central and oblique impact of a spherical particle with a wall in a viscous fluid. The particles are allowed to move in the fluid until they collide with the solid wall. The collision force on the particle is modeled by a soft-sphere collision scheme with a linear spring-dashpot system. The hydrodynamic force on the particle is solved directly from the RDPM. By following the trajectories of a particle, we investigate the effect of the collision model parameters to the dynamics of a particle close to the wall. We report in this paper the rebound velocity of the particle, the coefficient of restitution, and the particle slip velocity at the wall when a variety of different soft-sphere collision parameters are used.

Abstract:
Abstract In order to improve the safety of nuclear power plants, it is necessary to make sure measures against their severe accidents. Especially, in the case of a sodium-cooled fast reactor (SFR), there is a possibility of significant energy release due to formation of a large-scale molten fuel pool accompanied by re-criticality in the event of a core disruptive accident (CDA). It is important to ensure in-vessel retention that keeps and confines damaged core material in the reactor vessel even if the CDA occurs. CDA scenario initiated by Unprotected Loss Of Flow (ULOF), which is a typical cause of core damage, is generally categorized into four phases according to the progression of core-disruptive status, which are the initiating, early-discharge, material-relocation and heat-removal phases for the latest design in Japan. During the material-relocation phase, the molten core material flows down mainly through the control rod guide tube and is discharged into the inlet coolant plenum below the bottom of the core. The discharged molten core material collides with the bottom plate of the inlet plenum. Clarification of the accumulation behavior of molten core material with such a collision on the bottom plate is important to reduce uncertainties in the safety assessment of CDA. In present study, in order to make clear behavior of core melt materials during the CDAs of SFRs, analysis was conducted using the SIMMER-III code for a melt discharge simulation experiment [1] in which low-melting-point alloy was discharged into a shallow water pool. This report shows the validation results for the melt behavior by comparing with the experimental data.
