Welding of an Advanced High Strength Titanium Alloy

Many recently developed high strength titanium alloys do not possess the inherent good weldability of previous alloys in this material system. Difficulties have been encountered in achieving satisfactory weldment mechanical properties in several of these alloys. The present investigation was conducted to study the metallurgical response of one of these materials, Ti-6246, to arc welding. The goal was to identify the causes for inferior properties in advanced titanium alloy weldments and to provide guidelines for improved processing procedures to cor rect welding difficulties. Gas tungsten-arc welds made on 0.125 in. thick sheet were evaluated metallographically and with hardness, bend, and tensi le tests to characterize their properties in the aswelded condit ion and after various postweld heat treatments.

Paper was presented at the 55th A WS Annual Meeting held at Houston, Texas, during May 6-10, 1974. imens were utilized to more fully study this weldment region. These tests revealed that the weld and near heataffected zone regions were extremely hard and brittle as welded and after a normal postweld stress relief. Studies showed that this was caused by rapid auto-aging of an or thorhombic martensite phase formed during the weld thermal cycle. Solution heat treating after welding removed the orthorhombic martensite but failed to substantially improve weld ductility. Films of alpha phase precipitated at prior beta grain boundaries during the solution heat treatment were responsible for the low weld ductility in this condit ion. Based upon these results, a new postweld heat treatment was established which succ e s s f u l increased weld ductility by favorably altering the weld and heataffected zone alpha precipitation. This approach and others suggested by this investigation appear to be promising methods for improving the weldabi l i ty of advanced t i tanium alloys.
Modulating the cobalt dose range to manipulate multisystem cooperation in bone environment: a strategy to resolve the controversies about cobalt use for orthopedic applications

The paradoxical effect of cobalt on biological processes has aroused controversy regarding the application of cobalt-based biomaterials in bone regeneration. Tuning the dose range of cobalt ions may be a valid strategy to resolve the controversies about cobalt use for orthopedic applications. Recent progress in bone biology has highlighted the effects of multisystem cooperation (especially of osteoimmune, skeletal, and vascular systems) on bone dynamics. Before the application of this dose-tuning strategy, a deeper understanding of its dose-dependent effect on the cooperation of osteoimmune, skeletal, and vascular systems is needed. However, due to the difficulties with investigating the interaction of multiple systems in vitro, the multimodal effects of cobalt on bone homeostasis were investigated here, in an in vivo scenario. Methods: In vitro CCK8 assay and cytoskeletal staining were preformed to detecte the cell cytotoxic reaction in response to 0.1-100 ppm cobalt stimulation. Blood clot containing 0.1 to 5 ppm of cobalt were implanted in the rat calvarium defect. The gene profile of osteoimmune, skeletal, and vascular system as well as the systemic toxicity were evaluated via RT-qPCR, histological analysis and inductively coupled plasma mass spectrometry. The bone regeneration, osteoclastogenesis and vascularization were assessed by micro-ct and histological analysis. Results: Cobalt concentration below 5 ppm did not cause cell toxicity in vitro. No systemic toxicity was observed in vivo at 0.1-5 ppm cobalt concentration. It was found that the early cytokine profiles of the multiple interacting systems were different in response to different cobalt doses. Most of the anti-inflammatory, osteogenic, and proangiogenic factors were upregulated in the 1 ppm cobalt group at the early stage. In the late stage, the 1ppm group was most superior in bone regenerative effect while the 5 ppm group displayed the strongest osteoclastogenesis activity. Conclusions: The 1 ppm concentration of cobalt yielded the most favorable cooperation of the osteoimmune, skeletal, and vascular systems and subsequently optimal bone regeneration outcomes. Tuning the cobalt dose range to manipulate the cooperation of osteoimmune, skeletal, and vascular systems could be a promising and valuable strategy to prevent paradoxical effects of cobalt while preserving its beneficial effects.
Factors Present at Enrollment of College Freshmen That Predict Placement in Developmental Courses at Select Private Institutions

Factors Present at Enrollment of College Freshmen That Predict Placement in Developmental Courses at Select Private Institutions Attrition of college freshmen due, in part, to the lack of academic preparedness upon enrolling in college is an issue facing college and university administrators. Chief academic officers cannot ignore the fact that 30% of all students enrolling in postsecondary institutions require some form of “developmental” coursework. Institutional leaders need to be aware of predictors that determine the student’s need for enrollment in developmental courses and factors that influence student persistence. Administrators must focus on both the characteristics and experiences of students prior to college, as well as their experiences inside the classroom, and how these variables interrelate. To understand the variables that predict enrollment in developmental courses and the role developmental courses play in persistence, alumni (n=1725) from six select postsecondary institutions were surveyed. This was a survey research design involving a self report questionnaire, the College Student Persistence Questionnaire (CSPQ). There were 414 (24%) completed questionnaires returned. The grouping variable (dependent variable) was enrollment in one or more developmental courses. The predictor variables (independent variables) were gender, race, year of enrollment, high school grade point average (GPA), age at enrollment, withdrawal from an institution, year of graduation, transfer to an institution, attainment of a bachelor’s degree, transfer from an institution and age at graduation. Significant differences were found at the p < . 01 level with regard to high school GPA as a predictor of placement in developmental education courses. This study provides sufficient support for identifying the academic needs of first year students. Since student success is determined by student persistence, it is crucial that postsecondary institutions allocate funding for programs that support academic success for students. Developmental education is an institutional responsibility and it must be an institutional priority.
ANALYSIS OF THAILAND’S ECONOMIC STRUCTURE ON THE EXTENSIVE MARGIN OF ACTIVITY USING A DYNAMIC STOCHASTIC GENERAL EQUILIBRIUM MODEL

this research provides brief descriptions of Thailand’s economic structure on the extensive margin of activity by developing a dynamic stochastic general equilibrium model with the endogenous determination of the number of business entries on the market. To this aim, the model intended to point out the role of frictions (i.e. monetary and nonmonetary shocks) toward business fluctuations based on the endogenous firms’ entry and the contribution of financial accelerators. In particular, the framework exhibits the role of the banking system and the wage bill as advanced constraints in explaining the overall changes of the Thai economy between 2000Q1 to 2016Q1. The results of this research demonstrate the role of stabilization policy on a model where firm entry responds to several shocks and uncertainty environment. The outcomes of the model support the empirical finding of Poutineau and Vermandel (2015) on several aspects. The estimated model confirms that the effect of frictions on the model economy influence entrepreneurs ’decisions to enter into the goods market, and thus can be used to duplicate actual world data. There are four other main findings. i) Monetary transmission mechanisms influence on entrepreneurs’ decision which temporarily slowed down investment activities on both existing businesses and new entrants. Besides, the outcome reports the number of entrant are more likely to depend on the bank loans, not the one set by the authorities. ii) The endogenous firm entry implies the countercyclical number of business entry on the goods market toward banks markups and loan spread, hence being in line with the empirical evidence. iii) The end results of the model’s impulse responses, accounting for the frictions, appear to be contradicting the core prediction’s claims since the outcomes are unsound. The end results prove that there is a chance for entrepreneurs to simultaneously invest on both margins of activity. iv) The overall impulse response patterns of the model turns out to be significantly in line with the ones the researcher would have expected using empirical findings, in some cases, appear to be differ from the literature related to these sorts of models. These depend on the contribution of the financial accelerators that amplify the effects of frictions to the model economy. 3 rd International Conference on Management Economics and Social Sciences on 8 th 9 th July 2017, in Pattaya ,Thailand ISBN: 9780998900018 2
Teanby, N. A. (2015). Predicted detection rates of regional-scale meteorite impacts on Mars with the InSight

In 2016 NASA will launch the InSight discovery-class mission, which aims to study the detailed internal structure of Mars for the first time. Shortand long-period seismometers form a major component of InSight’s payload and have the potential to detect seismic waves generated by meteorite impacts. Large globally detectable impact events producing craters with diameters of ∼100 m have been investigated previously and are likely to be rare (Teanby and Wookey, 2011), but smaller impacts producing craters in the 0.5–20 m range are more numerous and potentially occur sufficiently often to be detectable on regional scales (.1000 km). At these distances, seismic waves will have significant high frequency content and will be suited to detection with InSight’s short-period seismometer SEIS-SP. In this paper I estimate the current martian crater production function from observations of new craters (Malin et al., 2006; Daubar et al., 2013), model results (Williams et al., 2014), and standard isochrons (Hartmann, 2005). These impact rates are combined with an empirical relation between impact energy, source-receiver Email address: n.teanby@bristol.ac. uk (N. A. Teanby) Preprint submitted to Icarus April 13, 2015 distance, and peak seismogram amplitude, derived from a compilation of seismic recordings of terrestrial and lunar impacts, chemical explosions, and nuclear tests. The resulting peak seismogram amplitude scaling law contains significant uncertainty, but can be used to predict impact detection rates. I estimate that for a short-period instrument, with a noise spectral density of 10−8 ms−2Hz−1/2 in the 1–16 Hz frequency band, approximately 0.1–30 regional impacts per year should be detectable with a nominal value of 1–3 impacts per year. Therefore, small regional impacts are likely to be a viable source of seismic energy for probing Mars’ crustal and upper mantle structure. This is particularly appealing as such impacts should be easily located with orbital imagery, increasing their scientific value compared to other types of events with unknown origins. Finally, comparison of the empirical results presented here with the modelling study of Teanby and Wookey (2011) provides constraints on the seismic efficiency, suggesting that values of ∼5×10−4 may be appropriate for impact generated seismic waves. Comparing explosion and impact datasets indicate that buried explosions are ∼10 times more efficient at generating seismic waves than impacts.
Teaching and Teacher Education

The present study focuses on the relationship between teachers' emotions, their instructional behavior, and students' emotions in class. 149 students (55% female, M age 1⁄4 15.63 years) rated their teachers' emotions (joy, anger, anxiety) and instructional behavior, as well as their own emotions in an experiencesampling study across an average of 15 lessons in four different subject domains. Intraindividual, multilevel regression analyses revealed that perceived teachers' emotions and instructional behavior significantly predicted students' emotions. Results suggest that teachers' emotions are as important for students' emotions as teachers' instructional behavior. Theoretical implications for crossover theory and practical recommendations for teachers are discussed. © 2014 Elsevier Ltd. All rights reserved.
Béziau's SP3A Logic and Logic Programming

We present some three-valued paraconsistent logics, in particular SP3A logic which has been recently introduced as a genuine paraconsistent logic. After discussing the relevance of some rules in classical logic, we motivate the need for paraconsistency. Then we mention areas of applications of non-monotonic reasoning in terms of programming semantics, and mention the relationship that exists between these semantics and logics. In particular we show that logic SP3A belongs to the family of D-elemental logics; these logics can characterize one of the semantics useful in the area of non-monotonic reasoning.
On GMM estimation of linear dynamic panel data models

The linear dynamic panel data model provides a possible avenue to deal with unobservable individual-specific heterogeneity and dynamic relationships in panel data. The model structure renders standard estimation techniques inconsistent. Estimation and inference can, however, be carried out with the generalized method of moments (GMM) by suitably aggregating population orthogonality conditions directly deduced from the underlying modeling assumptions. Different variations of these assumptions are proposed in the literature – often lacking a thorough discussion of the implications for estimation and inference. This paper aims to enhance the understanding of the assumptions and their interplay by connecting the assumptions and the conditions required to establish identification and consistency, derive the asymptotic properties, and carry out inference for the GMM estimator.
The Association between Ethnic Studies Course Completion and Graduation Rates ofUndergraduate Students of Color at a Predominately White Institution

Problem: The current national focus on college student success highlights the need to increase the graduation rates of students of color. To date, qualitative research has shown benefits from Ethnic Studies courses such as higher levels of student achievement, engagement and involvement, validation, mattering, and a sense of belonging for students of color. However, quantitative research examining the aggregate student data relating to Ethnic Studies course completion and college student success has not been conducted. Purpose: This quantitative study seeks to determine if there is a relationship between students of color completing Ethnic Studies courses and graduating from a predominantly White institution. Setting: The research took place at a large, public research university in the Pacific Northwest. Methodology: Data for almost 5,000 students of color were obtained from the Registrar; SPSS was used to run chi-square tests for independence for three research questions: 1. Is there an association between students of color completing Ethnic Studies courses and graduating? 2. Is there an association between the number of Ethnic Studies courses completed by students of color and graduation? 3. Is there an association between students of color completing Ethnic Studies courses and time-to-degree? Findings: A statistically significant association between completing Ethnic Studies courses and graduating was found for students of color; students who did not complete Ethnic Studies courses graduated at lower rates and those who completed Ethnic Studies courses graduated at higher rates. Taking zero Ethnic Studies courses and taking one Ethnic Studies course were the most significant contributors to the finding of an association, although in some cases completing two and three or more courses was also related. The association held when looking at students who did not graduate and those who graduated in more than four years, although there was not a significant association between completing Ethnic Studies courses and graduating in four years or less. Conclusions: An association does not equal causation, yet the association found between students of color completing Ethnic Studies courses and graduating shows that it is possible that Ethnic Studies courses are contributing to student success, as has been found in previous research. Additional research is needed to further understand the association that was found.
THE EFFECTS OF INULIN ON THE PHYSICOCHEMICAL CHARACTERISTICS OF REDUCED-FAT ICE CREAM

This study investigates the effects of inulin on the physicochemical properties of reducedfat ice cream (6% fat content) and its potential as a fat replacer. To this end, the rheology, thermal properties, particle size distributions, texture, and melting characteristics of 2% and 4% inulin-containing reducedfat ice creams were determined and compared with those of regular ice cream with 10% fat content (control) and inulinfree reducedfat ice cream. The experiments showed that the lower fat content (6%) significantly influenced the physicochemical characteristics of the ice cream products. Despite the minimal improvement in the rheology given to the 2% and 4% inulin contents, the glass transition temperature (Tg) of the inulin-containing reduced-fat ice creams was significantly elevated, resulting in enhanced product stability during frozen storage. The presence of inulin in the reduced-fat ice cream also induced the clustering of fat globules, resulting in the increase of the larger sized particles (1-10 μm) , but it significantly decreased the hardness of the reduced-fat ice cream. Moreover, the presence of 4% inulin lowered the melting rate of the reducedfat ice cream to more resemble that of the regular ice cream. All in all, the experimental findings verify the prospects of inulin, especially at the level of 4%, as a fat replacer in the reduced-fat ice cream product.
Transformer and seq2seq model for Paraphrase Generation

Paraphrase generation aims to improve the clarity of a sentence by using different wording that convey similar meaning. For better quality of generated paraphrases, we propose a framework that combines the effectiveness of two models – transformer and sequence-to-sequence (seq2seq). We design a two-layer stack of encoders. The first layer is a transformer model containing 6 stacked identical layers with multi-head self attention, while the second-layer is a seq2seq model with gated recurrent units (GRU-RNN). The transformer encoder layer learns to capture long-term dependencies, together with syntactic and semantic properties of the input sentence. This rich vector representation learned by the transformer serves as input to the GRU-RNN encoder responsible for producing the state vector for decoding. Experimental results on two datasets-QUORA and MSCOCO using our framework, produces a new benchmark for paraphrase generation.
Neural Dependency Parsing of Biomedical Text: TurkuNLP entry in the CRAFT Structural Annotation Task

We present the approach taken by the TurkuNLP group in the CRAFT Structural Annotation task, a shared task on dependency parsing. Our approach builds primarily on the Turku neural parser, a native dependency parser that ranked among the best in the recent CoNLL tasks on parsing Universal Dependencies. To adapt the parser to the biomedical domain, we considered and evaluated a number of approaches, including the generation of custom word embeddings, combination with other in-domain resources, and the incorporation of information from named entity recognition. We achieved a labeled attachment score of 89.7%, the best result among task participants.
Optimisation du traitement des carcinoses péritonéales évoluées par la réduction tumorale chirurgicale et l'association cisplatine-adrénaline chez le rat

Objectif - Evaluer et comparer les effets therapeutiques de la cytoreduction chirurgicale et de la chimiotherapie intraperitoneale par l'association cisplatine/adrenaline dans un modele de carcinose peritoneale evoluee chez le rat. Materiel et methodes - Une carcinose peritoneale evoluee etait obtenue 20 jours apres l'injection de 1 × 10 6 cellules cancereuses coliques DHD/K12/PROb dans la cavite peritoneale de rats BDIX syngeniques. La fulguration des nodules tumoraux au bistouri electrique associee a une omentectomie et a une splenectomie entrainait une reduction maximale de la carcinose peritoneale. La chimiotherapie intraperitoneale comprenait du cisplatine (3 mg/kg) dans 20 mL de serum physiologique, associe ou non a de l'adrenaline (2 mg/kg) afin de avoriser a penetration tissulaire du cisplatine. Resultats - La reduction tumorale chirurgicale seule n'augmentait pas la survie des animaux. La chimiotherapie intraperitoneale seule, par cisplatine ± adrenaline, augmentait la duree de survie des animaux sans les guerir. L'association d'une chirurgie de reduction et d'une injection post-operatoire de cisplatine et d'adrenaline permettait la guerison de 4 animaux sur 5. Conclusions - la chirurgie de cytoreduction tumorale combinee a une chimiotherapie intraperitoneale associant cisplatine et adrenaline pourrait etre un traitement efficace des carcinoses peritoneales.
Effect on Oral Health Estimates of Response Disparities: Results from the Survey of Oral Health Status, Maryland School Children 2005-2006

In a survey of Maryland children between 2005 and 2006, 55% of those who returned a questionnaire (collecting demo-social characteristics and self-reported oral health) participated in a screening exam (collecting objective oral health). This paper examines the differences in socio-economic and oral health status among screening examination respondents and non-respondents and the effect of non-response on estimates of oral health. Two-sided z-tests, t-tests, and chi-square tests were used for appropriate data and a significance level of 0.05 is applied for all comparisons. Population estimates of demosocial characteristics among screening examination respondents were not significantly different from non-respondents. Although an overall low response rate may potentially bias our population estimates, if the sample is representative of the target population then weight adjustment, stratification, and imputation at the analysis stage can limit this bias.
Ortho-Prostho Management of Hypodontia Using Fibre- Reinforced Composite Resin Bridge: An Interdisciplinary Approach

Hypodontia is the congenital absence of <6 teeth because of agenesis. The absence of teeth may be unilateral or bilateral. Several treatment options are indicated to treat hypodontia, including the maintenance of primary teeth or space redistribution for restorative treatment with partial adhesive bridges, tooth transplantation, and implants. However, an interdisciplinary approach is the most important requirement for the ideal treatment of hypodontia. This paper presented the work on a single abutment, single pontic cantilever fibre-reinforced composite bridge to replace bilaterally missing maxillary lateral incisors using Ceramage with glass fibres namely Fibrex Lab Pontic System which is incorporated as the fibre-reinforcement of the bridge frame. Indirect fabrication of this prosthesis in laboratory gives a better finish and aesthetic outcome than the direct technique in clinic.
