How the Emotional Climate (Field) Impacts Performance

Independently of the creativity movement, others have demonstrated the benefits of creating positive fields. I have reviewed a number of cases involving field below and added some from my own creativity experiences. I then explore the psychological explanation of why such fields are effective and go on to the findings of recent brain research, which not only reinforce the benefits of positive fields but also throw light on the difficulty of creating them. Finally, I offer some suggestions from my own experience of what can be done to create positive fields. I believe that this should now be the focus of our efforts: to the extent that we are successful, we should get the creativity and innovation we need as a by‐product.     

Growth and Characterization of YbBCO Films on Textured Gd2O3 Buffer-Layered Ni Tapes: All Sol–Gel Process

YbBa₂Cu₃O_7?x (YbBCO) thick films were grown on buffered, cube-textured Nickel tapes by sol–gel dip-coating method. Yb-123 films were prepared using solutions of Yb, Ba, and Cu organometallic compounds. A solution-based Gd₂O₃ buffer layer was deposited by dip-coating process with excellent texture and uniformity. The texture development and surface morphology of the buffer-layer films were examined by X-ray diffraction, pole figures, and ESEM analysis. Microstructure and characterization of Yb-123 films were done by ESEM, EDS, and XRD analysis. T _c and J _c were conducted by four-wire measurement method     

Effects of initial powder vibrogrinding on the properties of AlN - BN composites

A study has been made on the effects of initial vibroground powders with various grain sizes on the properties of AlN - BN composites. As the specific surface of these powders increases, so do the density, mechanical strength, and thermal resistance of the composites.     

Stress-Corrosion Fracture of 12Kh18AG18Sh Steel in Chloride-Containing Media with Copper Cations

We studied the corrosion and corrosion-mechanical resistance of new austenitic high-nitrogen 12Kh18AG18Sh steel for the retaining rings of turbogenerators in aqueous solutions containing chlorides and copper (II) cations. A significant decrease in the corrosion resistance of this steel (P constitutes 0.52–14.50 mm/year) and in its resistance to corrosion cracking and corrosion-fatigue fracture in CuCl₂ solutions was established. We also calculated the coefficients of linear parts of the kinetic diagrams of fatigue fracture of the steel under study in air with a humidity of 40% and in 22% NaCl and CuCl₂ solutions.     

Relation Between Firing Conditions Grain Boundary Structure and Magnetic Properties in Polycrystalline MnZn-Ferrites

The influence of the firing conditions on the nanoscale structure of the grain boundaries and on the magnetic properties of polycrystalline MnZn-ferrites is investigated, on specimens of nearly identical microstructures. High oxygen partial pressures favor accumulation of impurity ions at the triple points. Under appropriate oxygen pressures homogeneous accumulation of impurities along the grain boundaries may occur, revealing therefore chemically pure grains and low hysteresis losses; simultaneously an increase of the grain boundary resistivity occurs that results to low eddy current losses. Managing the raw material impurity cations towards controlled grain boundary structures leads to the synthesis of MnZn-ferrites with power losses similar to those achieved when high purity raw materials are used together with externally introduced additives.     

The making of the MCM/70 microcomputer

MCM/70, manufactured by Micro Computer Machines (MCM), was a small desktop microcomputer designed to provide the APL programming language environment for business, scientific, and educational use. MCM was among the first companies to fully recognize and act upon microprocessor technology's immense potential for developing a new generation of cost-effective computing systems. This article discusses the pioneering work on personal microcomputers conducted at MCM in the early 1970s and, in particular, the making of the MCM/70 microcomputer.     

On Optimal Signal–Filter Pairs

We extend the notion of an optimal signal–filter pair to the case where n-convolution is used instead of cyclic convolution. We construct n-optimal n-adic signals for all n = 2, 3, . . ..     

Multifrequency gyrotron with high-efficiency synthesized waveguide converter

The results of numerical simulation and experimental investigation of a prototype of a megawatt multifrequency gyrotron for controlled thermonuclear fusion facilities are presented. In experiments, the gyrotron has operated at six frequencies in the range 105–152 GHz with small diffraction losses in the internal quasi-optical system and a high Gaussian mode content in the output beam.
