STKE: Larger Pipe, Lower Resistance

Lower pitch is larger, yet falling pitches shrink.

Experiments using diverse paradigms, including speeded discrimination, indicate that pitch and visually-perceived size interact perceptually, and that higher pitch is congruent with smaller size. While nearly all of these studies used static stimuli, here we examine the interaction of dynamic pitch and dynamic size, using Garner's speeded discrimination paradigm. Experiment 1 examined the inter...

Why Do Larger Buyers Pay Lower Prices? Intense Supplier Competition

The paper provides a theoretical explanation of the common claim that larger buyers pay lower prices. In the model, suppliers compete more aggressively for the business of larger buyers, much as they do in “boom” periods in Rotemberg and Saloner (1986).

Larger Mammalian Body Size Leads to Lower Retroviral Activity

Retroviruses have been infecting mammals for at least 100 million years, leaving descendants in host genomes known as endogenous retroviruses (ERVs). The abundance of ERVs is partly determined by their mode of replication, but it has also been suggested that host life history traits could enhance or suppress their activity. We show that larger bodied species have lower levels of ERV activity by...

Resistance Coefficients for Non-Newtonian Flows in Pipe Fittings

Global opportunities in Pipe in Pipe technology

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...
