INITIAL INVESTIGATION OF SELECTIVE LASER SINTERING LASER POWER VS . PART POROSITY USING IN-SITU OPTICAL COHERENCE TOMOGRAPHY

Additional types of process sensors could be useful in further improving consistency of Selectively Laser Sintered (SLS) parts. Optical Coherence Tomography (OCT) has shown promise as a new SLS process sensor which can yield depth resolved data not attainable with conventional sensors. This study investigates the use of OCT as a tool to determine part porosity. Various laser powers were used during the build and the in-situ OCT data corresponding to the various laser powers are compared. The finished part was then imaged using X-ray Computed Tomography (XCT). Porosity data was obtained and is compared with the OCT data. Introduction Selective Laser Sintering Selective Laser Sintering (SLS) is a powder bed fusion process developed at UT Austin in the late 1980’s and early 1990’s. It was one the first commercialized additive manufacturing technologies. SLS continues to be relevant as an additive technique in various industries including aviation and the 3D printed medical devices market among others in part due to its ability to produce parts comparable to those created by injection-molding. A schematic demonstrating how the SLS process works is shown in Figure 1 from Gibson et al [1]. Figure 1.

Towards industrial applications of graphene electrodes

Since the first isolation of graphene in 2004 by mechanical exfoliation from graphite, many people have tried to synthesize large-scale graphene using various chemical methods. In particular, there has been a great number of advances in the synthesis of graphene using chemical vapor deposition (CVD) on metal substrates such as Ni and Cu. Recently, a method to synthesize ultra-large-scale (∼30 inch) graphene films using roll-to-roll transfer and chemical doping processes was developed that shows excellent electrical and physical properties suitable for practical applications on a large scale. Considering the outstanding scalability/processibility of roll-to-roll and CVD methods as well as the extraordinary flexibility/conductivity of graphene films, we expect that transparent graphene electrodes can replace indium tin oxide in the near future.
Syddansk Universitet Transcription factor ZNF 25 is associated with osteoblast differentiation of human skeletal stem cells

Background: The differentiation of human bone marrow derived skeletal stem cells (known as human bone marrow stromal or mesenchymal stem cells, hMSCs) into osteoblasts involves the activation of a small number of well-described transcription factors. To identify additional osteoblastic transcription factors, we studied gene expression of hMSCs during ex vivo osteoblast differentiation. Results: Clustering of gene expression, and literature investigation, revealed three transcription factors of interest – ZNF25, ZNF608 and ZBTB38. siRNA knockdown of ZNF25 resulted in significant suppression of alkaline phosphatase (ALP) activity. This effect was not present for ZNF608 and ZBTB38. To identify possible target genes of ZNF25, we analyzed gene expression following ZNF25 siRNA knockdown. This revealed a 23-fold upregulation of matrix metallopeptidase 1 and an 18-fold upregulation of leucine-rich repeat containing G protein-coupled receptor 5 and RAN-binding protein 3-like. We also observed enrichment in extracellular matrix organization, skeletal system development and regulation of ossification in the entire upregulated set of genes. Consistent with its function as a transcription factor during osteoblast differentiation of hMSC, we showed that the ZNF25 protein exhibits nuclear localization and is expressed in osteoblastic and osteocytic cells in vivo. ZNF25 is conserved in tetrapod vertebrates and contains a KRAB (Krueppel-associated box) transcriptional repressor domain. Conclusions: This study shows that the uncharacterized transcription factor, ZNF25, is associated with differentiation of hMSC to osteoblasts.
Electret-based microgenerators under sinusoidal excitations: an analytical modeling

The fast growing number of mobile and wearable applications has driven several innovations in small-scale electret-based energy harvesting due to the compatibility with standard microfabrication processes and the ability to generate electrical energy from ambient vibrations. However, the current modeling methods used to design these small scale transducers or microgenerators are applicable only for constant-speed rotations and small sinusoidal translations, while in practice, large amplitude sinusoidal vibrations can happen. Therefore, in this paper, we formulate an analytical model for electret-based microgenerators under general sinusoidal excitations. The proposed model is validated using finite element modeling combined with numerical simulation approaches presented in the literature. The new model demonstrates a good agreement in estimating both the output voltage and power of the microgenerator. This new model provides useful insights into the microgenerator operating mechanism and design trade-offs, and therefore, can be utilized in the design and performance optimization of these small structures.
Bridging the Gap between Home and School: Creating Inclusion through Culturally Relevant and Responsive Pedagogy

With the increase of student diversity within the Greater Toronto Area, fostering a commitment to student learning has become a great concern (Ontario Ministry of Education, 2009). As a result, adapting instruction to integrate students’ identities and cultural diversities becomes imperative to fostering inclusion in the elementary classroom. Through the adoption of culturally relevant/responsive pedagogy (CRRP), this qualitative research study investigated teachers’ implementation of pedagogy to support inclusive learning of students in culturally diverse public classrooms within public elementary schools in the Greater Toronto Area. Semi-structured interviews were conducted with educators who identified with implementing a culturally relevant and responsive pedagogical approach in their classrooms. In exploring CRRP, it was found that the teacher participants commonly identified CRRP as pertaining to student-centered teaching with a focus on students’ needs and interests, and student empowerment through critical reflection and identity building. The findings also revealed that CRRP requires collaborative efforts and supports of students, teachers, parents and professionals in the community, which when limited can serve as barriers for educators adopting the approach. As a result, implications were identified for the broader education community as well as for teachers who wish to adopt CRRP in their teaching, in addition to several proposed recommendations.
Towards thermal comfort prediction for the older population : a review of aging effect on the human body Divine

Research has revealed that aging effect on the organs of the body and body functions can affect the response of the older person in a given environment. However human thermoregulation models used in the prediction of the comfort of the human body in a given environment have been designed to represent an average person. This research aims at developing a customized computer model for predicting thermal comfort of old persons and is based on IESD-Fiala model. From published literature, data on the effect of aging on the basal metabolic rate (BMR), cardiac output (C.O.), body weight (BW) and body surface area (BSA), height (HT) were extracted and used for the development of a ‘typical’ old person model. A transient simulation carried out to compare the skin temperatures of the average person (existing Fiala model) and old person (new model) under the same environmental conditions showed that the old person may feel cooler at the exposed skin areas i.e. hands and feet than the average person.

Variation of Water Retention Characteristics due to Particle Rearrangement under Zero Gravity

Controlled delivery of water to plant root zone remains a challenge in the exploration of plant growth under zero gravity, in which soil water retention characteristics are difficult to predict due to possible soil particle rearrangement and pore restructuring. This paper aims to provide an understanding of the effect of soil particle rearrangement on the water retention characteristics in zero gravity. A three-dimensional pore network model is developed to predict water retention characteristics under two forms of particle packing—cubic packing (most porous) and rhombohedral packing (most compact). The pore-throat distributions, as input parameters to the network model, are derived from particle size distribution under the two forms of particle arrangement. The model simulations reveal the quantitative variation of water retention characteristics due to particle rearrangement. Soil particle rearrangement that occurs during the drying process is shown to significantly change the water retention curve when.
A Preliminary Study on Using Multi-Nozzle Polymer Deposition System to Fabricate Composite Alginate/Carbon Nanotube Tissue Scaffolds

Three-dimensional composite alginate/single wall carbon nanotube (SWCNT) scaffolds encapsulated with endothelial cells were fabricated by a multi-nozzle biopolymer freeform deposition system. This system enables the converting of CAD designed scaffold pattern into process toolpaths and the use of computer control program to guide the nozzle deposition at spatial position for layered fabrication of 3D tissue scaffolds. The morphological, mechanical, structural and biological properties of as-fabricated scaffolds were characterized by optical microscope, SEM, Microtensile testing machine, Alamar Blue Assay, and Live-Dead Assay, respectively. The multi-nozzle deposition system demonstrated a highly efficient and effective process to build tissue scaffold or cell embedded constructs. Characterization results showed that the incorporation of SWCNT into alginate not only enhanced the mechanical strength of the scaffolds but also improved the cell affinity and the interaction with substrate. Further cell culture experimental results also showed that the incorporation of SWCNT in alginate enhanced endothelial cell proliferation compared with pure alginate scaffold.
What Can We Learn About the Ideology of the Newest Supreme Court Justices?

Abstract In this article, we present a principled method for updating estimates of the ideology of Supreme Court justices based on each new vote they cast. We apply this method to the ideological positions of the newly appointed members of the Court: John Roberts, Samuel Alito, and Sonia Sotomayor. This approach allows us to gain not only an estimate of justices' ideologies but also a greater understanding of the level of uncertainty we should have about these values, including how much we can learn about a new justice's views after he or she has cast a given number of votes on the Court.
Seismic attenuation imaging with causality

Seismic data enable imaging of the Earth, not only of velocity and density but also of attenuation contrasts. Unfortunately, the Born approximation of the constant-density visco-acoustic wave equation, which can serve as a forward modelling operator related to seismic migration, exhibits an ambiguity when attenuation is included. Different scattering models involving velocity and attenuation perturbations may provide nearly identical data. This result was obtained earlier for scatterers that did not contain a correction term for causality. Such a term leads to dispersion when considering a range of frequencies. We demonstrate that with this term, linearized inversion or iterative migration will almost, but not fully, remove the ambiguity. We also investigate if attenuation imaging suffers from the same ambiguity when using non-linear or full waveform inversion. A numerical experiment shows that non-linear inversion with causality convergences to the true model, whereas without causality, a substantial difference with the true model remains even after a very large number of iterations. For both linearized and non-linear inversion, the initial update in a gradient-based optimization scheme that minimizes the difference between modelled and observed data is still affected by the ambiguity and does not provide a good result. This first update corresponds to a classic migration operation. In our numerical experiments, the reconstructed model started to approximate the true model only after a large number of iterations.
Generalizing the Taylor Principle: New Comment

In this paper, we provide determinacy conditions, i.e. conditions ensuring the existence and uniqueness of a bounded solution, in a purely forward-looking linear Markov switching rational expectations model. We thus settle the debate between Davig and Leeper (2007) and Farmer et al. (2010). The conditions derived by the former are valid in a subset of bounded solutions only depending on a finite number of past regimes, that we call Markovian. However, in the complete bounded solution space, the new determinacy conditions we derive are tighter. Nevertheless, when unique, the solution coincides with the Markovian solution of Davig and Leeper (2007). We finally illustrate our results in the standard new-Keynesian model studied by Davig and Leeper (2007) and Farmer et al. (2010).
Evaluating the Basis for NK Sensitivity and NK Resistance in Prototypic NK Sensitive and Resistant Cell Line

Tumors develop numerous mechanisms through which they evade NK cell attack. Several molecules secreted by YAC-1 cells and P815 cells were evaluated for their interaction with NK cell receptors. The affinity characterization of NK cell receptor with tumor expressed ligands will help in understanding the binding patterns required for the activation of NK cell activity. A detailed understanding of the mechanisms of tumor evasion and tumor susceptibility in the tumor microenvironment is essential for developing effective cancer therapies. The multi-faceted recognition pattern of tumor derived factors by NK activating receptors and every accessible surface involved in this binding event has been explored. Interaction between the known factors (galactin-3, CD63 (AD1 antigen), gp70 and p30) present on the surface membrane of mastocytoma P815 cell with NK inhibitory receptor Ly49A on NK cell was explored for evaluating the basis for tumor resistance to NK mediated lysis and interaction between T-cell lymphoma YAC-1 cell derived ligands(p30CA, p12, p15MA and p15E) with NK activating receptor Ly49H was evaluated for potential basis for NK susceptibility by YAC cells addressed by computational approaches which further help to develop NK based cancer therapeutic strategies (Graphic 1).
Intraspecific genetic structure of white sucker (Catostomus commersoni) in northeastern North America as revealed by mitochondrial DNA polymorphism

Nous avons utilise les polymorphismes de longueur de fragment de restriction sur l'ADN mitochondrial (ADNmt) afin d'etudier l'influence des glaciations du Pleistocene sur la structure genetique intraspecifique et sur la distribution du meuniernoir (Catostomus commersoni) aunord-est de l'Amerique duNord. Un total de 312 meuniers noirs provenant de 13 populations, dont une comprenant un ecotype nain (Catostomus commersoni utawana), ont ete analyses. Une moyenne de 93 fragments par individu et 40 haplotypes ont ete generes par neuf endonucleases de restriction. Quatre petits groupes distincts ont ete identifies mais la majorite des genetypes retrouves (70%) n'ont ete associes a aucun de ces groupes. La continuite phylogenetique et le chevauchement de la distribution de quelques un de ces groupes identifies sont associes a la large distribution de l'espece au sud de la calotte de glace lors des evenements glaciaires du Pleistocene. L'analyse hierarchique de la variabilite de l'ADNmt revele une subdivision regionale significative entre le nord-ouest et le sud-est du bassin de drainage du fleuve St-Laurent ainsi qu'une structure significative au niveau de la population. Comme la forme naine presentait un haplotype identique a celui retrouve parmi la forme normale, nous suggerons une divergence sympatrique comme explication la plus probable de l'origine de l'ecotype nain et normal echantillone dans les Adirondacks.
Long‐term evolution of an accretionary prism: The case study of the Shimanto Belt, Kyushu, Japan

The Shimanto Belt in SW Japan is commonly described as a paleo‐accretionary prism, whose structure is explained by continuous accretion like in modern accretionary prisms such as Nankai. We carried out a structural study of the Cretaceous to Miocene part of the Shimanto Belt on Kyushu to test this hypothesis of continuous accretion. Most deformation structures observed on the field are top‐to‐the‐SE thrusts, fitting well the scheme of accretionary wedge growth by frontal accretion or underplating. In particular, the tectonic mélange at the top of the Hyuga Group records a penetrative deformation reflecting burial within the subduction channel. In contrast, we documented two stages of extension that require modifying the traditional model of the Belt as a “simple” giant accretionary wedge. The first one, in the early Middle Eocene, is mostly ductile and localized in the foliated bases of the Morotsuka and Kitagawa Groups. The second one, postdating the Middle Miocene, is a brittle deformation spread over the whole belt on Kyushu. Integrating these new tectonic features to existing data, we propose 2‐D reconstructions of the belt evolution, leading to the following conclusions: (1) Erosion and extension of the margin in the early Middle Eocene resulted from the subduction of a trench‐parallel ridge. (2) The Late Eocene to Early Miocene evolution is characterized by rapid growth of the prism, followed by a Middle Miocene stage where large displacements occurred along low‐angle out‐of‐sequence thrusts such as the Nobeoka Tectonic Line. (3) From middle Miocene, the strain regime was extensional.
Shadow colours for painters

This article presents a simple, practical method for painting realistic shadow colours. The method involves the Munsell colour system. A straight line is drawn on the Munsell hue leaf, whose hue is that of the object being painted. The line starts at the Munsell specification of the object’s colour (when viewed in full light), and ends one value step below N0, on the neutral axis. The colours on this line are the colours of the object in various degrees of shadow. The Reilly paint mixing approach is presented as an intuitive way for a painter to mix these colours. A step-by-step shadow painting demonstration is given, using readily available materials. Although presented non-technically here, the method has a technical basis, which has been published previously.
The measurement and antecedents of affective, continuance and normative commitment to the organization

Organizational commitment has been conceptualized and measured in various ways. The two studies reported here were conducted to test aspects of a three-component model of commitment which integrates these various conceptualizations. The affective component of organizational commitment, proposed by the model, refers to employees' emotional attachment to, identification with, and involvement in, the organization. The continuance component refers to commitment based on the costs that employees associate with leaving the organization. Finally, the normative component refers to employees' feelings of obligation to remain with the organization. In Study 1, scales were developed to measure these components. Relationships among the components of commitment and with variables considered their antecedents were examined in Study 2. Results of a canonical correlation analysis suggested that, as predicted by the model, the affective and continuance components of organizational commitment are empirically distinguishable constructs with different correlates. The affective and normative components, although distinguishable, appear to be somewhat related. The importance of differentiating the components of commitment, both in research and practice, is discussed.
MAPS FOR DESIGN REFLECTION

Abstract In this paper the authors introduce, apply, and discuss a set of design artefacts called maps, intended to support design researchers in capturing, analysing, and reflecting upon design processes. The maps focus on reflection with regard to the role of sources of inspiration and design materials in the emergence and transformation of design ideas. The paper revolves around a specific case, the design of media facades – i.e. displays that are an integrated part of a building's facade – as part of the development of material for a bid in an architectural competition for a new modern art museum in Warsaw, Poland. They discuss their findings from using the maps for design reflection in this case, with a particular focus on the importance of employing artefacts to support design reflection.
A Multicriteria- Spatial Decision Support System (MC-SDSS) development for siting a landfill in the Province of Torino (Italy)

The present paper proposes a spatial multicriteria approach for supporting Decision-Makers in the siting process of a Municipal Solid Waste landfill in the Province of Torino (Italy). In particular, the contribution illustrates the development of a Multicriteria-Spatial Decision Support System based on the integration of Geographic Information Systems and a specific Multicriteria Decision Analysis technique, named Analytic Network Process (ANP). This technique, which represents the generalization of the more well-known Analytic Hierarchy Process to dependences and feedbacks, is particularly suitable for dealing with complex decision problems which are characterized by inter-relationships among the elements at stake. The application allows the dependence relationships among the criteria to be assessed, and the relative importance of all the elements that play an influence on the final choice to be evaluated. The purpose of the study is to generate a suitability map of the area under analysis for locating a waste landfill, paying particular attention to the contribution that the spatial ANP offers to sustainability assessments of undesirable facilities. To this end, the simple network structure has been used and both exclusionary and non-exclusionary criteria have been identified and grouped into clusters. The results are obtained in the form of suitability maps analysed through ilwis 3.3 software (52North, ITC, Enschede, The Netherlands) and have been further verified through a sensitivity analysis with reference to the clusters priorities in order to test the robustness of the proposed model. The main findings of this research have proved that the spatial ANP is a useful tool to help technicians to make their decision process traceable and reliable. Moreover, this approach helps Decision-Makers to undertake a sound reflection of the siting problem. Finally, the implementation of the spatial ANP technique gives an originality value to the present research because it represents one of the first applications at both the national and international level.
