Preparing and writing a failure analysis report

Afailure analysis report is the summation of all of the tests and analyses performed during the course of an investigation. The report coalesces the results and presents them in a concise and logical format that describes the particulars of the subject being studied, conveys pertinent information gathered from testing and analysis, and logically and accurately interprets and explains the data and results.     

The effects of NO passivation on the radiation response of SiO2/4H-SiC MOS capacitors

The radiation response of SiO₂ gate oxides grown on 4H-SiC to NO passivation is presented for the first time. The effects of gamma radiation on Q_eff are similar for n-4H-SiC MOS capacitors both with and without NO passivation, but are different in sign (negative) compared to SiO₂ on Si. The variation in D_it with total dose, however, is different for the passivated versus the unpassivated samples. Comparisons between Si SOI and 4H-SiC suggest that properly passivated SiC MOSFETs should have good radiation tolerance.     

Selective attention: A reevaluation of the implications of negative priming.

The notion that inhibitory processes play a critical role in selective attention has gained wide support. Much of this support derives from studies of negative priming. The authors note that the attribution of negative priming to an inhibitory mechanism of attention draws its support from a common assumption underlying priming procedures, together with the procedure that has been used to measure negative priming. The results from a series of experiments demonstrate that selection between 2 competing prime items is not required to observe negative priming. This result is demonstrated across several experiments in which participants named 1 of 2 items in a second display following presentation of a single-item prime. The implications of these results for existing theories of negative priming are discussed, and a theoretical framework for interpreting negative priming and several related phenomena is forwarded.

USB设计常见错误分析

USB已经问世11年了，但人们每天都还是不断发现创新的方法来利用这套通讯协议；与此同时，他们也在成千种的设计方案中重复着相同的错误。USB和其他协议有着众多相似之处，这比工程师在PS／2与RS-232领域时一再犯下相同错误的程度还要不可思议。此外，面对严格的标准规范，工程师所犯的错误可能会造成不符USB规范的代价。     

The parabrachial nucleus is essential for acquisition of a conditioned odor aversion in rats.

Rats with bilateral ibotenic acid lesions of the gustatory zone of the parabrachial nuclei (PBN) failed to acquire a conditioned taste aversion (CTA) in Exp 1. They also failed to acquire a conditioned odor aversion (COA) when the olfactory cue was presented on an odor disk in Exp 2 or when it was presented in water in Exp 3. The failure to acquire the COA was not due to an inability to detect or use olfactory stimuli because the lesioned rats displayed neophobia to a novel odor in Exp 3 and used an olfactory cue to predict the availability of an aversive capsaicin solution in Exp 4. Together, the results demonstrate that, as with CTA learning, PBN cell bodies are essential for the establishment of a specific association between an olfactory conditioned stimulus and a lithium chloride unconditioned stimulus.

Two-year behavior outcomes of project towards no tobacco use.

Presents a 2-year follow-up data from a school-based tobacco use prevention project designed to test the effectiveness of 3 primary components in social influence programs. The components either teach refusal skills, awareness of social value misperceptions, or physical consequences. Curricula were tested with a randomized experiment involving 48 junior high schools. Data suggested that a physical-consequences curriculum is successful at attenuating increases in adolescent smokeless tobacco use, cigarette experimentation may be attenuated by various approaches, and a comprehensive program with all 3 components was necessary to attenuate increases in weekly use of both forms of tobacco. These results also indicate that school-based tobacco use interventions can be effective at least 2 years postprogram, after students make their transition to high school.

Special stainless steels for the process industry

The requirements for and properties of steels to resist corrosion in many industrial applications are discussed. The economic aspects are also briefly considered.     

A simpler method for calculating the cost of conservation subsidies for an electric utility

This article presents a highly aggregated method of calculating the cost of conservation subsidies for an electric utility company. The cost is expressed in terms of the company's total expenditures on subsidies versus the reduction in electricity demand due to customers' extra conservation investments. We argue that the highly aggregated method would serve as a useful complement to the detailed programme by programme calculations normally performed to determine conservation cost-effectiveness. The simpler method is demonstrated with an application to the conservation programmes of the Pacific Gas and Electric Company.     

Double dissociation of effects on learning of medial versus lateral hyperstriatal lesions in pigeons.

Three experiments examined the effects of medial and lateral hyperstriatal lesions in two groups of pigeons. In Experiment 1, both hyperstriatal groups were impaired, relative to unoperated and operated control groups, in postoperative performance of preoperatively acquired serial reversal of both spatial and visual discriminations. The deficits of the two hyperstriatal groups appeared both quantitatively and qualitatively similar. Experiment 2 found that performance of spatial reversals was disrupted in the medial, but not in the lateral, hyperstriatal group by a long intertrial interval. Experiment 3 found that acquisition of simultaneous matching-to-sample was disrupted by lateral, but not by medial, hyperstriatal lesions; the lateral group also showed a lower rate of response to the sample stimulus than any of the other groups. Implications of these findings for current theories of hyperstriatal function are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
