No full textHere is a curious book. Its title-page declares "The Artist's Book of Fables" but its pre-title-page has "Fables, Original and Selected, with a Memoir of the Author." After that title-page, it is identical with "Fables, Original and Selected" as in our copy printed by John Murray in 1833. There is again an AI at the front and an index of engravings and engravers at the back. I found that copy twenty years ago. I had found an inferior copy twenty-two years before that. At that time, I noted Aesopic fables here including "Stone Broth" and "The Mouse and the Oyster."This is a hardbound book (hard cover)James Northcote, R.A
Ellis-van Creveld Syndrome: Systemic And Oral Findings
No full textAims: To present a case of Ellis-van Creveld syndrome highlighting the systemic and oral manifestations and expand the phenotypic spectrum of the disorder. Case description: A 4-year-old female, with an initial diagnosis of Ellis-van Creveld syndrome, was referred for dental treatment. The patient had hexadactyly of the hands, thorax disproportionate to the shortened limbs, hypopigmented and dry skin, short stature, a wide gap between the 1st and 2nd toes of the right foot and markedly dystrophic toenails. The oral manifestations were upper labial frenulum causing large vestibule and absence of diastema, labiogingival frenulum, enamel hypoplasia, conical teeth, claw-like cusp, oligodontia, microdontia and malocclusion. Conclusions: Ellis-van Creveld syndrome is one among several syndromes with oral manifestations that demands the participation of a multidisciplinary team to better patient assessing, treatment and monitoring. Dentists have the leading role in the control and treatment of the oral manifestations.222109112Alves-Pereira, D., Berini-Aytés, L., Gay-Escoda, C., Ellis-Van Creveld Syndrome Case report and literature review (2009) Med Oral Patol Oral Cir Bucal, 14, pp. E340-E343da Silva, E.O., Janovitz, D., de Albuquerque, S.C., Ellis-van Creveld syndrome: report of 15 cases in an inbred kindred (1980) J Med Genet, 17, pp. 349-356Kurian, K., Shanmugan, S., Harsh Vardah, T., Chondroectodermal dysplasia (Ellis-van Creveld syndrome) A report of three cases with review of literature (2007) Indian J Dent Res, 18, pp. 31-34Hills, C.B., Kochilas, L., Schimmenti, L.A., Ellis-van Creveld syndrome and congenital heart defects: Presentation of an additional 32 cases (2011) Pediatr Cardiol, 32, pp. 977-982Tompson, S.W., Ruiz-Perez, V.L., Blair, H.J., Sequencing EVC and EVC2 identifies mutations in two-thirds of Ellis-van Creveld syndrome patients (2007) Hum Genet, 120, pp. 663-670Ruiz-Perez, V.L., Ide, S.E., Strom, T.M., Mutations in a new gene in Ellis-van Creveld syndrome and Weyers acrodental dysostosis (2000) Nat Genet, 24, pp. 283-286Galdzicka, M., Patnala, S., Hirshman, M.G., A new gene, EVC2, is mutated in Ellis-van Creveld syndrome (2002) Mol Genet Metab, 77, pp. 291-295Ruiz-Perez, V.L., Tompson, S.W., Blair, H.J., Mutations in two nonhomologous genes in a head-to-head configuration cause Ellis-van Creveld syndrome (2003) Am J Hum Genet, 72, pp. 728-732Ruiz-Perez, V.L., Goodship, J.A., Ellis-van Creveld syndrome and Weyers acrodental dysostosis are caused by cilia-mediated diminished response to hedgehog ligands (2009) Am J Med Genet C Semin Med Genet, 151 C, pp. 341-351Biggerstaff, R.H., Mazaheri, M., Oral manifestations of the Ellis-van Creveld syndrome (1968) J Am Dent Assoc, 77, pp. 1090-1095Aminabadi, N.A., Ebrahimi, A., Oskouei, S.G., Chondroectodermal dysplasia (Ellis-van Creveld syndrome): a case report (2010) J Oral Sci, 52, pp. 333-336Hunter, M.L., Roberts, G.J., Oral and dental anomalies in Ellis van Creveld syndrome (chondroectodermal dysplasia): report of a case (1998) Intern J Paed Dent, 8, pp. 153-157Fukuda, A., Kato, K., Hasegawa, M., Recurrent knee valgus deformity in Ellis-van Creveld syndrome (2012) J Pediatr Orthop B, 21, pp. 352-355Cahuana, A., Palma, C., Oral manifestations in Ellis-van Creveld syndrome (2004) Report of five cases.

Turbulent entrainment in a shearless mixing layer at the edge of a cloud
No full textThree-dimensional direct numerical simulations which combine the Eulerian description of temperature, vapor content and velocity with a Lagrangian ensemble of cloud water droplets are used to study the turbulent entrainment and subsequent mixing of clear air with a cloudy air filament. The study is conducted in a shearless mixing layer setup which is adjusted to realistic conditions at a cumulus cloud boundary. The magnitude of turbulent velocity fluctuations in- and outside the cloud can be varied independently. We find that the evolution of the cloud water droplet ensemble depends slightly only on the contrast of turbulent velocity fluctuations in- and outside the cloud filament. The buoyancy feedback on the flow via the evaporating droplets causes a transient amplification of all fluctuations before the turbulence eventually decays. We study the evolution of the probability density functions of droplet size as well as of supersaturation, temperature and vorticity at the droplet positions
Quality in blended learning environments – Significant differences in how students approach learning collaborations
No full textEvaluating the quality of student experiences of learning in a blended environment requires the careful consideration of many aspects that can contribute to learning outcomes. In this study, university students in first year engineering were required to collaborate and inquire in a blended course design over a semester-long course. This study investigates their approaches to inquiry and online learning technologies as they collaborated both in class and online. The results identify sub-groups within the population sample (n > 200) which reported qualitatively different experiences of how they approached inquiry and used the online learning technologies. The results also measure aspects of their collaborations which help to explain why some students were more successful than others. The outcomes of the study have important implications for teaching and course design and the effective evaluation of blended experiences of university student learning.Robert A.

Non-Linear Time Series Analysis of Deep Groundwater Levels: An application to the Veluwe
No full textThe objective of this study is to improve the simulation of deep groundwater levels by time se- ries models with pre-defined impulse response functions. This is attempted by adding a conceptual non-linear root zone model to simulate the recharge series to the model and by testing the use of a separate response function for the percolation zone. Three root zone models are developed based on two different recharge mechanisms: preferential flow, percolation, and a combination of the two. The performance of these models is compared to a linear model that is commonly used in time se- ries models to simulate the recharge. The approach is applied to groundwater level measurements in the Veluwe, a largely forested area in the Netherlands characterized by thick unsaturated zones. The effect of groundwater extractions and land reclamations is added to the model to further im- prove the simulation of the groundwater levels. The models are tested on three observations wells with increasing thickness of the unsaturated zone, varying from 7 m to 29 m to 49 m. The results show that model performance is improved by the implementation of a non-linear root zone model, particularly in simulating the peaks and lows in the groundwater levels. The recharge fluxes simulated by the non-linear models show different patterns that are physically more realistic than those simulated by the linear model. It is shown that different recharge series result in simulated groundwater levels that are very similar. This is a clear example of equifinality and it is recommended to introduce new sources of information to validate the modelled processes (e.g., water content measurements of the percolation zone or actual evaporation data). For the shallow well, the models with a single response function are selected as the best. The largest improvements for the deeper groundwater levels are obtained by the addition of a separate response for the percolation zone. For example, the average deviation from the observed ground- water levels decreased 0.18 m to 0.08 m for the deepest observation well by applying the separate response function. The models with an additional response function were better at simulating the estimated time to peak, the time it takes a recharge pulse to cause a peak in the groundwater levels. The time to peak is introduced in this research as a qualitative indicator to validate the modelled processes. The simulated responses indicate that the groundwater levels respond very quickly to water that leaves the root zone, even though the percolation zone is tens of metres thick. For each of the observations wells it is investigated if adding the effect of groundwater extrac- tions or land reclamations of Flevoland to the models improves the simulation of the groundwater levels. For the shallow well it is concluded that either the effect of land reclamations or groundwater extractions needs to be taken into account. Since these two stresses are correlated, it is concluded that only one of these should be taken into account when no further information is available to con- strain the models. For the medium deep well, the additional stresses did not significantly improve model performance and it is concluded that they do not have to be taken into account for this well. For the deep well, model performance is improved by both stresses. The largest improvements are observed when the effect of groundwater extractions is considered in the model. For implemen- tation of these stresses, the entire simulation period should be used for calibration, or constraints have to be implemented to obtain realistic results.Water ResourcesWater ManagementCivil Engineering and Geoscience

The Descriptive Features and Quantitative Aspects of Students' Observed Online Learning: How Are They Related to Self-Reported Perceptions and Learning Outcomes?
No full textThis article uses digital traces to help identify students’ online learning strategies by making a clear distinction between the descriptive features (the proportional distribution of students’ different online learning actions) and quantitative aspects (the total number of the online learning sessions), a distinction that has not been properly addressed in extant research. It also examines the extent to which the descriptive features and quantitative aspects of students’ observed online learning behaviors are related to students’ self-reported perceptions of the blended learning environment and the academic learning outcomes. A cohort of 317 Australian undergraduates enrolled in a compulsory engineering course participated in the study. A hierarchical cluster analysis, based on the different proportions of the types of online learning activities in which students were involved, identified two qualitatively different online learning strategies: content and practice oriented. The content-oriented learners not only had significantly more online learning sessions but also performed significantly better on both the formative and summative assessments, than their practice-oriented counterparts. Moreover, a higher proportion of students reporting more negative perceptions were observed to adopt practice-oriented strategies, whereas a higher proportion of students reporting better perceptions were observed to adopt content-oriented strategies. The study results serve as triangulated evidence for the previous self-reported research on the relations between students’ perceptions and strategies. The results of the study also offer a number of ideas for teaching and curriculum design in blended courses in order to improve the quality of students’ blended learning experiences.Feifei Han, Robert A.
