Data for a NACA 23012C Aerofoil Pitched about its Quarter Chord Axis. Volume I: Pressure data from static and ramp function tests, with photographs of oil-flow visualisation tests

Herein is presented the collected data for tests in which a NACA 23012C aerofoil was subjected to a variety of ramp type displacements in pitch about the quarter chord position at low Reynolds numbers. In addition, the results of static tests and oil-flow visualisation experiments on the aerofoil are displayed

Contract Report for The Science And Engineering Research Council. Contract Number Gr/F/06760. G.U. Aero Report 9201

This document constitutes the final report for SERC award No. GR/F/06760. It first details the work programme of the original proposal made in 1987 and notes the work done to illustrate completion and extensions beyond that proposed. For brevity, we confine the technical discussion to the salient features of a particular aerofoil, albeit the work was an integral part of a larger programme on dynamic stall. The extent of this work may be gleaned from the accompanying enclosures representing some recent activity at Glasgow University. Two of the main technical results from the present authors are worthy of note in that the first (i.e. a correletion for incipient dynamic stall) has been used both in industry (VAWT Ltd) and research (under SERC GR/F/63466) to propose new aerofoil shapes for wind turbines. The second, however, (negative lift at large incidence during ramp-down motions from the stalled condition) has generated a new research activity (funded under SERC GR/H167U). This and future prospects are discussed prior to the concluding remarks. These remarks express the authors opinion of the success and overall value of the programme

Single-grain and multi-grain OSL dating of river terrace sediments in the Tabernas Basin, SE Spain

River terraces represent important records of landscape response to e.g. base-level change and tectonic movement. Both these driving forces are important in the southern Iberian Peninsula. In this study, Optically Stimulated Luminescence (OSL) dating was used to date two principal river terraces in the Tabernas Basin, SE Spain. A total of 23 samples was collected from the fluvial terraces for dating using quartz OSL. Sixteen of the samples could not be dated because of low saturation levels (e.g. typical 2xD0 < 50 Gy). The remaining seven samples (5 fossil and 2 modern analogues) were investigated using both multi-grain and single-grain analysis. Single grain results show that: (i) measurements from multi-grain aliquots overestimate ages by up to ∼ 4 ka for modern analogues and young samples (<5 ka), presumably because (ii) the presence of many saturated grains has biased the multi-grain results to older ages. Despite the unfavourable luminescence characteristics we are able to present the first numerical ages for two terrace aggradation stages in the Tabernas Basin, one at ∼16 ka and the other within the last 2 ka

Tomato: a crop species amenable to improvement by cellular and molecular methods

Tomato is a crop plant with a relatively small DNA content per haploid genome and a well developed genetics. Plant regeneration from explants and protoplasts is feasable which led to the development of efficient transformation procedures. In view of the current data, the isolation of useful mutants at the cellular level probably will be of limited value in the genetic improvement of tomato. Protoplast fusion may lead to novel combinations of organelle and nuclear DNA (cybrids), whereas this technique also provides a means of introducing genetic information from alien species into tomato. Important developments have come from molecular approaches. Following the construction of an RFLP map, these RFLP markers can be used in tomato to tag quantitative traits bred in from related species. Both RFLP's and transposons are in the process of being used to clone desired genes for which no gene products are known. Cloned genes can be introduced and potentially improve specific properties of tomato especially those controlled by single genes. Recent results suggest that, in principle, phenotypic mutants can be created for cloned and characterized genes and will prove their value in further improving the cultivated tomato.
