The effect of isoprenoid side chain length of ubiquinone on life span
Medical Hypotheses, 2003The isoprenoid side chain length of ubiquinone (Q) can have an effect on the life span of mammals. The short living mouse and rat have Q(9), while primates have Q(10) as the major form. Ubiquinones (Qs) having longer hydrophobic tail are likely more imbedded in the mitochondrial inner membrane than the ones having shorter tails.

Articulatory and Phonological Determinants of Word Length Effects in Span Tasks
The Quarterly Journal of Experimental Psychology Section A, 1992Several previous studies have shown that memory span is greater for short words than for long words. This effect is claimed to occur even when the short and long words are matched for the number of syllables and phonemes and so to provide evidence for subvocal articulation as being one mechanism that underlies memory span (Baddeley, Thomson, & ...

A probabilistic approach to the lengths of free pipeline spans
Applied Ocean Research, 1995Free spans of submarine pipelines may occur as the result of seabed unevennesses. The length of such a free span is crucial for the structural behavior and safety of a pipeline. Until measurements of actual span lengths become available during the operation of a pipeline, the length of a free pipeline span will be an uncertain quantity owing to ...

On the Minimal Total Path Length of a Spanning Tree [PDF]
, 2013 The notions of a balance node and the total path length with respect to a node u of a spanning tree are defined. We show that the total path length of a spanning tree with respect to u is minimal if and only if u is a balance node. An algorithm is also given to locate a balance node.

Optimal Simple Span Lengths for Flexible Guideways
Journal of Structural Engineering, 1984In the design of elevated vehicle/guideway systems several parameters play important roles in the dynamic performance. The vehicle inertial and suspension properties, guideway mass per unit length, span length, structural damping characteristics and surface finish tolerances are important factors.

Length of Life Span as a Factor in Regulating Populations
Ecology, 1934For a number of years the writer and students working in his laboratory have been studying some of the problems relating to the length of the life span for some of the common animals of the local fauna. In a number of instances, it has been observed that there are rather rigidly imposed limits to the normal length of life.

Optimum Spans’ Lengths of Multi-span Reinforced Concrete Beams Under Dynamic Loading
2012In the design of continuous beams, say bridges, achieving an economical layout is one of the primary objectives, and requires simultaneous consideration of cost and layout variables. This study aims to figure out an explicit methodology for the optimum layout design of multi-span reinforced concrete beams under dynamic loadings in order to optimize the

“Minimax Length Links” of a Dissimilarity Matrix and Minimum Spanning Trees
Psychometrika, 1995A theorem is proved stating that the set of all “minimax links”, defined as links minimizing, over paths, the maximum length of links in any path connecting a pair of objects comprising nodes in an undirected weighted graph, comprise the union of all minimum spanning trees of that graph.
