We calculate the visual light curve of CAL 87 based on the assumption that an accreting steadily burningwhite dwarf irradiates the accretion disk and the secondary star, as suggested by van den Heuvel et al. (1992). We find a reasonable fit including the following sources of visual light: 1. the secondary star where the energy from irradiation is spread out over the surface, 2. the accretion di...

Pollen, charcoal, magnetic susceptibility, and bulk density data provide the first paleoecological record spanning the last 33,000 years from the western cordillera of the Peruvian Andes. Sparse super-puna vegetation existed before 30,000 cal yr B.P. around Lake Compuerta (3950 m elevation), prior to a sedimentary hiatus that lasted until c. 16,200 cal yr B.P. When sedimentation resumed, a glac...

Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the f...

We have previously identified the cystic fibrosis transmembrane regulator (CFTR)-interacting protein CAL and demonstrated that CAL modulates CFTR plasma membrane expression by retaining CFTR within the cell. Here, we report that in addition to regulating membrane expression, CAL also regulates the expression of mature CFTR. The co-expression of hemagglutinin-tagged or Myc-tagged CAL with green ...

At the past two CALITE conferences I have described a methodology for creating knowledgebased CAL. This paper describes how that methodology has evolved. The Domain-Analysis Based Instruction System, a CAL system that utilises the methodology is then described in detail.

We apply the ASM semantics framework to define the await construct in the context of concurrent ASMs. We link CAL programs to concurrent control state ASMs with turbo ASM submachines.

Courseware abstraction is an approach to CAL whereby the lesson author creates a general parametetized CAL lesson that is then applied to many concrete examples. This approach has the following advantages over alternative approaches to lesson development: it is cost efficient; it facilitates lesson verification; it encourages the provision of as many examples as are desirable; it simplifies the...

In the literature on cost-effectiveness analyses, there has recently been considerable debate on the way of measuring the production gain caused by a new treatment as well as its proper evaluation. In this paper, we propose a general framework for the discussion of such questions in the form of a general equilibrium model with separate health variables. It is shown how the standard methods of c...

Taxidermy specimens are cloaked in animal skin; organic material that can decay or be eaten by insects. This essay examines the tactile relationship between this changeable skin-creature, and figures of taxidermist natural history curator turn twentieth century museum. Using Bristol Museum as a case study, it argues were not inert stilled within museum collections. It explores how taxidermy mee...
