Word-association commonality: A standardized test and a theory.

The Verdun association list (VAL) is a word-association test with stimulus words selected to elicit a high frequency of common responses among normal adults. Commonality, reaction time, and response stability measures are incorporated in the test. Standardization was based on 2 independent, representative metropolitan samples of normal employed adults—575 Ss in all. Validation groups consisted of (1) 2 independent samples each comprising 100 working and 100 nonworking hospitalized mental patients; (2) all 15 psychiatric patients, some working and some not, who attended the night treatment center of a general hospital over a 2-mo period, and (3) the 44 Canadian Army volunteers at 1 induction session at a recruitment center who were rejected as unfit for military service on various nonphysical grounds. The high agreement between cut-off scores and all external criteria suggested that the VAL could be effective in a wide variety of industrial, clinical, and experimental settings.

Cantilever and Suspended Span Roof Framing System

AISC has proposed an alternative to the use of joist girders. That proposal is based on a system that was originally developed for bridge structures. The concept was first applied to architectural structures many years ago, but was abandoned for several reasons. One principle reason for this was the system's dependence on artificial loads to balance the presence of real loads. Because of this, the system may be very susceptible to overload. The use of the Gerber System will produce a structure that is nearly half the depth of a Joist Girder System. That should be the primary reason for choosing to use the Gerber System. This paper proposes a design approach that allows this system to be used with confidence and safety. The proposed approach is based on a stiffness analysis instead of a strength analysis. The purpose of this paper is to encourage the safe use of the Gerber Framing System.     

A Convenient High Activity Catalyst for the Sonogashira Coupling of Aryl Bromides

A mixture of Na₂PdCl₄, CuI and (t‐Bu)₃PH⁺BF₄⁻ (molar ratio 4 : 3 : 8) dispersed in H₂N(i‐Pr)₂⁺Br⁻ can be used as a “single source” precatalyst for the Sonogashira coupling of aryl bromides with various aryl‐ and alkylacetylenes in HN(i‐Pr)₂ solvent. Arylacetylenes require just 0.005 mol % of Pd catalyst at 80 °C, with TOFs ranging between 3,200 and 10,000 h⁻¹.     

Schall‐Längsleitung im Holz‐Mischbau

Flanking transmission of timber elements in the building shell with concrete construction parts. The following article describes the test of the flanking transmission of timber elements in the building shell with concrete construction parts for high rise buildings and the effects of different construction methods, like multi‐storey elements, separation boards and the influence of installation layers. The version with the junction of the elements on a level with the ceiling elements and the design of an installation layer cause an substantial improvement of the normalized sound pressure level difference.     

Vitamin E deficiency in dogs does not alter preferential incorporation ofRRR-α-tocopherol compared withall rac-α-tocopherol into plasma

The plasma and lipoprotein transport ofRRR andall rac-α-tocopherols, labeled with different amounts of deuterium [2R,4′R,8′R-α-[5-C²H₃]tocopheryl acetate (d ₃ RRR-α-tocopheryl acetate] and 2RS, 4′RS, 8′RS-α-[5,7-(C²H₃)₂]tocopheryl acetate (d ₅ all rac-α-tocopheryl acetate), was studied in adult beagle dogs that had been fed a vitamin E-deficient (−E; two dogs) or supplemented (+E; two dogs) diet for two years. We set out to test the hypothesis that the activity of the hepatic tocopherol binding protein (which is thought to preferentially incorporateRRR-α-tocopherol into the plasma) is up-regulated by vitamin E deficiency. Labeled α-tocopherols increased and decreased similarly in plasma of both −E and +E dogs. Irrespective of diet,d ₃ RRR-α-tocopherol was preferentially secreted in plasma. Thus, vitamin E deficiency in dogs does not markedly increase the apparent function of the hepatic tocopherol binding protein. We also studied vitamin E transport in a German Shepherd dog with degenerative myelopathy (DM). Based on the coincident appearance ofd ₃ RRR-α-tocopherol in plasma and chylomicrons, we suggest that the abnormality in DM may be associated with abnormal vitamin E transport resulting from an impaired function of the hepatic tocopherol binding protein.     

Lubricated Rolling and Sliding Wear of a SiC-Whisker-Reinforced Si3N4 Composite against M2 Tool Steel

Mineral oil lubricated rolling and sliding wear of SiC whisker (SiC_w) reinforced Si₃N₄ composite and monolithic Si₃N₄ prepared identically against M2 tool steel were investigated using a cylinder-on-cylinder apparatus. Wear of this Si₃N₄ was higher than that of the composite. Wear of the steel against Si₃N₄ was also higher than that against the composite. Relatively larger scale microfracture occurred in the Si₃N₄ than in the composite; more pullout and microchipping of carbide particles were observed in the steel against Si₃N₄ than against the composite. Polishing of the worn surfaces of the steel occurred in both sliding and rolling tests. This was attributed to fine, hard wear debris circulating in the contact area. Spalling was observed in the steel sliding against Si₃N₄ but not in the steel sliding against the composite.
