Energy foundations can reduce carbon footprint and lead to energy savings. Understanding the process of heat migration in soil is therefore of great interest in the field of geotechnical engineering. However, limited literature exists on the thermo-dynamic interaction and structural performance of an energy foundation and the surrounding soil. Lab testing of energy foundations remains inexpensi...

In the context of performance-based approaches for the design or assessment of concrete structures, time is the decisive variable and the durability issues are pronounced. Also, the reliability aspects are important as they is attribute to service life, maintenance, inspection, repair and the lifecycle cost – see also ISO 13823 (2008) and the fib Model Code (2010). Evidently, durability and rel...

To the Editor: The halo nevus is thought to be of little concern in children. In adults, however, a new-onset has been suggested harbinger melanoma either within or at distant cutaneous noncutaneous sites, according case reports and small series.1Epstein W.L. Sagebeil R.

The prefrontal cortex (PFC) in humans has been studied for more than a century, but many crucial questions about its functions remain unanswered. This paper will highlight a few key differences between human and animal PFCs, and between the human PFC (HPFC) and other parts of the human brain. We then make a case that the HPFC is critically important for executing behaviors over time and integra...

Using social cognitive, control-value theory as a framework, this study examined how students’ cognitive appraisals (task value and self-efficacy) and negative achievement emotions (boredom and frustration) relate to their overall satisfaction with an online course and their continuing motivation to enroll in future courses. Service academy undergraduates (N = 481) completed a survey that asses...

Title of Dissertation: Planetesimal Evolution and the Formation of Terrestrial Planets Zoë Malka Leinhardt, Doctor of Philosophy, 2005 Dissertation directed by: Dr. Derek C. Richardson Department of Astronomy To create an accurate numerical model of solar system formation it is necessary to understand how planetesimals, the planetary building blocks, evolve and grow into larger bodies. Traditio...

To the Editor: As a result of the worldwide use of screening mammography, many breast biopsies are now performed for small, usually nonpalpable, mammographically detected abnormalities. The breast biopsies of screened abnormalities contain a large number of socalled minimal breast cancers. This term includes all non-invasive cancers (Tis) and invasive cancers up to 1 cm in diameter (minimal inv...

Bill S-17, Parliament’s effort to comply with international trade rules by extending pharmaceutical patent protection to 20 years, inadvertently opened the door to a broader investigation of the inner workings of the country’s pharmaceutical patent legislation. Industry Minister Brian Tobin says the bill must become law by August or Canada “will be in trouble with the World Trade Organization.”...

Contemporary software systems used in the dynamic simulation of rigid bodies suffer from problems in accuracy, performance, and robustness. Significant allowances for parameter tuning, coupled with the careful implementation of a broad phase collision detection scheme is required to make dynamic simulation useful for practical applications. A geometrically accurate constraint formulation, the P...
