Few psychologists today are aware of the seminal role played by learning theorist Edward C. Tolman in the early development of the field of behavior genetics. Tolman was the first to publish a study of selective breeding for maze-learning ability in rats. He continued to foster research in this field by supporting the work of his students, particularly Robert C. Tryon. Tryon carried out the fir...

This study investigates the interaction of lexical tone and intonation in embedded clauses in the two-tone Kwa language Akan. The claim is that embedded clauses show recursive prosodic phrasing at the level of intonation phrases (ι-phrase). The prosodic boundary of an embedded clause is expressed by means of a pitch register reset. At the boundary, lexical tonal distinctions are maintained in t...

The following application note represents a general guideline for mounting LEDs of the Golden DRAGON with Lens product family. A basic overview of the construction of LEDs and important design rules for the development of LED systems are provided. In addition, the principal processing steps are illustrated for the Golden DRAGON ARGUS LED, and general information about mounting is summarized. In...

* This work was supported by the U. S. Department of Energy, Nevada Operations Office, under contract No. DE-AC0896NV1178 Abstract – We show how to select the frequencies for a two-tone sinewave test of an analog to digital converter. The frequencies are selected in a manner to guarantee nearly uniform coverage of a selected ellipse in the phase plane. A proof that the selected frequencies prov...

A new approach on the synthesis of Si anodes for Li-ion batteries is reported, combining advantages of both nanoparticulated and continuous Si films. A multilayered configuration prototype is proposed, comprising amorphous Si arranged in nanostructured, mechanically heterogeneous films, interspersed with Ta nanoparticle scaffolds. Particular structural features such as increased surface roughne...

In recent years, the control or eradication of scrapie and any other transmissible spongiform encephalopathies (TSEs) possibly circulating in the sheep population has become a priority in Britain and elsewhere in Europe. A better understanding of the epidemiology of scrapie would greatly aid the development and evaluation of control and eradication strategies. Here we bound the range of key epi...

The preparation of polymer membrane selective to Iron(II) ion and its application to ion-selectiveelectrode is reported here. PVC membrane contains Iron–selective N-phenylaza-15-crown-5 asionophore. The membrane electrode is highly selective to Iron(II) ion and exhibit good linearresponse over a wide concentration range of 1.0 × 10-2 to 1.0 × 10-6 M with Nernstian slope of29.2 ± 0.6 mV per deca...

neurodegeneration is the pathophysiological basis for permanent neurological disabilities in multiple sclerosis (ms); thus neuroprotection is emerging as a therapeutic approach in ms research. modulation of excitotoxicity by inhibition of nmdars has been suggested for neuroprotection, but selective antagonisation of the nr2b subtype of these receptors, a subtype believed to play a more pivotal ...

A functional expression is introduced that relates scattered X-ray intensities from a still or a rotation snapshot to the corresponding structure-factor amplitudes. The new approach was implemented in the program nXDS for processing monochromatic diffraction images recorded by a multi-segment detector where each exposure could come from a different crystal. For images containing indexable spots...

Previous studies have concluded that thoroughbred racehorse speed is improving very slowly, if at all, despite heritable variation for performance and putatively intensive selective breeding. This has led to the suggestion that racehorses have reached a selection limit. However, previous studies have been limited, focusing only on the winning times of a few elite races run over middle and long ...
