RTM: Design and Implementation
The results of the design and development of RTM are presented in three parts. First, the various models (task-graph, real-time macro data-flow, and an object-oriented abstract implementation model) are presented, as are the relationships among the models. Second, the RTM language (an annotated …

The effects of hydrogen on the deformation and fracture behavior of the metastable beta-titanium alloy, TIMETAL(RTM) 21S
The metastable $\beta$-titanium alloy, TIMETAL$\sp\circler$ 21S, exhibits a sharp ductile-to-brittle transition when the hydrogen concentration is increased slightly above H/M $=$ 0.22. To understand this sharp transition, a series of experiments was devised to test for the possible hydrogen …

The Metaphysics of Mental Representation
The representational theory of mind (RTM) explains the phenomenon of intentionality in terms of the existence and nature of mental representations. Despite the typical characterisation of mental representations in terms of their semantics, RTM is best understood as a metaphysical – more …

An Evaluation of a Yeast-Derived Mannan Oligosaccharide and Its Mode of Action in Swine
Bio-MosRTM (Alltech, Inc., Nicholasville, KY) is a mannan oligosaccharide product, derived from the outer cell wall of the yeast Saccharomyces cerevisiae, with a theorized mode of action regarding the association of its mannan component with microbes expressing mannose-sensitive type-1 fimbriae. In …
