In the Presidential Address at the meeting of the Canadian Psychological Association, Winnipeg, June, 1983 the author examines the relationship between psychology and the other behavioral sciences and several areas of technological change, particularly those involving computer science and information processing and advances in health technology. Specifically, the social impact of technological change and the role of psychology in the planning for, and the implementation and evaluation of, the effects of technological change are stressed. Human primacy is proposed as an alternative to technological primacy in the development of societal goals. Recommendations are offered for action, including the establishment of a national institute to focus on the area of the impact on humanity of the technological revolution.

A competitive enzyme linked immunosorbent assay with antigen immobilized on the solid phase was developed to measure alpha 2-macroglobulin in rat serum. The cross reactivity with albumin and hemoglobin was eliminated by use of IgG fractions that were isolated after chromatography on Cibacron Blue F3-GA Sepharose immobilized rat whole serum and hemoglobin Sepharose. Blocking materials and pH of the coating buffer had no effect on the amount of alpha 2-macroglobulin that binds to the plate. When the coating amount of alpha 2-macroglobulin was 100 ng/well, at pH 7.4, 10 mM Tris-HCl containing 150 mM sodium chloride and the IgG amount added was 60 ng/well, then albumin and hemoglobin did not affect the assay at concentrations of 150 micrograms/ml or 200 micrograms/ml. This assay is useful for measuring the concentration of alpha 2-macroglobulin in normal and irradiated rat serum. 相似文献

While many measures of viewpoint goodness have been proposed in computer graphics, none have been evaluated for ribbon representations of protein secondary structure. To fill this gap, we conducted a user study on Amazon's Mechanical Turk platform, collecting human viewpoint preferences from 65 participants for 4 representative superfamilies of protein domains. In particular, we evaluated viewpoint entropy, which was previously shown to be a good predictor for human viewpoint preference of other, mostly non‐abstract objects. In a second study, we asked 7 experts in molecular biology to find the best viewpoint of the same protein domains and compared their choices with viewpoint entropy. Our results indicate that viewpoint entropy overall is a significant predictor of human viewpoint preference for ribbon representations of protein secondary structure. However, the accuracy depends on the type and composition of the structure: while most participants agree on good viewpoints for structures with mainly beta sheets, viewpoint preference varies considerably for complex arrangements of alpha helices. Finally, experts tend to choose viewpoints of both low and high viewpoint entropy to emphasize different aspects of the respective structure. 相似文献

A comparative evaluation by such parameters as alleviation of pain syndrome, improvement of peripheral resistance and vegetotrophic processes, a decline in pareses and sensory disorders has been performed in 3 groups of patients: group 1 underwent benzohexonium electrophoresis, group 2 benzohexonium electrophoresis in the magnetic field produced by the unit "Polyus-I" followed by low-frequency electrotherapy with bipolar impulse current, group 3 benzohexonium electrophoresis in the magnetic field from the unit "ADMT-Magnipuls" followed by low-frequency electrotherapy with bipolar impulse current. The best clinical and physiological results were reported in group 3 patients. 相似文献

Thermal analysis of peritectic alloys 总被引:1,自引:0,他引:1
Predictions that increasing cooling rate will result in increasing elevation of the apparent peritectic arrest temperature have been confirmed for Cd-Ag and Zn-Cu alloys in line with observations of Al-Ti alloys. The shape of the peritectic cooling curve is related to the competition between the peritectic transformation and direct crystallization from the melt in the formation of the secondary phase. The effect on solidification of the relative depressions of the and liquidus during cooling is considered. 相似文献

Soluble MHC Ags and anti-Id (anti-anti-MHC) Abs have both been shown to inhibit MHC alloantigen-specific B cell responses in vivo. We hypothesized that some anti-idiotypic Abs function as divalent molecular mimics of soluble HLA alloantigen. To test this idea, we studied two well-defined anti-idiotypic mAbs, T10-505 and T10-938, elicited in syngeneic BALB/c mice by immunization with CRll-351, an HLA-A2,24,28-specific mAb. Each anti-Id induced "Ab-3" Abs in rabbits that cross-reacted with HLA-A2 but not with HLA-B Ags. Furthermore, each anti-Id could bind to and block Ag recognition by Ha5C2.A2, a human homologue of mAb CRll-351. Both anti-Id mAb displayed weak reactivity with the human mAb SN66E3, which recognized an overlapping but distinct determinant of HLA-A2 Ags; neither reacted with human mAb MBW1, which recognized a nonoverlapping HLA-A2 determinant. Amino acid sequence comparison of mAb CRII-351 heavy and light chain variable region complementarity-determining regions (CDRs) with those of mAb Ha5C2.A2 and SN66E3 revealed short regions of homology with both human mAb; a large insert in the light chain CDR1 of mAb SN66E3 distinguished it from both CRll-351 and Ha5C2.A2. The amino acid sequences of mAb T10-505 and T10-938, which differed markedly from each other, revealed no homology to the alpha2 domain sequence of HLA-A*0201 that contains the CRll-351 mAb-defined epitope. We conclude that structurally different anti-Id Abs can mimic a polymorphic conformational epitope of an HLA Ag. In the case of T10-505 and T10-938 mimicry was not based on exact replication of the epitope by the hypervariable loops of the anti-Id mAb. 相似文献

yambo is an ab initio code for calculating quasiparticle energies and optical properties of electronic systems within the framework of many-body perturbation theory and time-dependent density functional theory. Quasiparticle energies are calculated within the GW approximation for the self-energy. Optical properties are evaluated either by solving the Bethe-Salpeter equation or by using the adiabatic local density approximation. yambo is a plane-wave code that, although particularly suited for calculations of periodic bulk systems, has been applied to a large variety of physical systems. yambo relies on efficient numerical techniques devised to treat systems with reduced dimensionality, or with a large number of degrees of freedom. The code has a user-friendly command-line based interface, flexible I/O procedures and is interfaced to several publicly available density functional ground-state codes.

Conclusions Ultimately, of course, a prototype power plant will be built at a power level appropriate for planned future commercial operations. This could use the same ETF/ DPP driver or a new one tailored to the plant size and with less experimental flexibility than the ETF driver. With the experience and data gained from a number of small demonstration reactors, and from the operation of the ETF/DPP driver and target factory, it is quite likely that a variety of plant sizes options will be available at that time.The scenario explored here is a relatively low-cost development program for fusion energy, which encourages technology transfer to American industry at an early stage. If the government builds an ETF driver, target factory, a single-shot experiment area, and a burst mode facility, commercial companies may be interested in building their own small demonstration reactors which would be supported by the government facilities. The fact that the ETF and any number of DPPs could be supported by the same driver and target factory means that the incremental cost of trying many alternatives is small. The fact that IFE demonstration reactors can test all relevant parameters at low power means that IFE has no extremely high-cost (multi-billion dollar) development facility to build in order to demonstrate engineering feasibility, i.e., there is no large development hurdle to surmount. We can, indeed, start small and work our way larger as the results justify. The result of this approach may produce competitive IFE power plant designs from a few to a few thousand megawatts. 相似文献
