We present two cases of Pneumocystis carinii pneumonia in apparently immunocompetent preterm infants presenting with unexplained respiratory distress associated with a predominantly interstitial process on the chest radiograph. Definite diagnosis was promptly established on the detection of cyst forms in the lung fluid obtained by non-bronchoscopic bronchoalveolar lavage, and a favourable outcome was achieved. 相似文献

A new and advanced sampling technique far-field interpolation with a nonredundant number of samples on plane-polar geometry has been experimentally validated for cases of both complex and only-amplitude measurements. Experimental results show good stability of the interpolation algorithm with respect to noise and the lack of samples in the case of a limited scanning area 相似文献

Reconfigurable arrays by phase-only control 总被引:3,自引:0,他引:3
Bucci O.M. Mazzarella G. Panariello G. 《Antennas and Propagation, IEEE Transactions on》1991,39(7):919-925
Due to space or cost reasons, a single array antenna can be required to radiate more than one pattern, each pattern being selected by an electronic control, in which only the phase can be modified. A synthesis method for such a problem that is able to determine both the common amplitude and the various phases in an integrated way is presented. Moreover, the approach is flexible enough to take into account additional constraints and allows an efficient implementation. Some test cases showing the effectiveness of the method are presented 相似文献

Oris is a tool for qualitative verification and quantitative evaluation of reactive timed systems, which supports modeling
and analysis of various classes of timed extensions of Petri Nets. As most characterizing features, Oris implements symbolic
state space analysis of preemptive Time Petri Nets, which enable schedulability analysis of real-time systems running under
priority preemptive scheduling; and stochastic Time Petri Nets, which enable an integrated approach to qualitative verification
and quantitative evaluation. In this paper, we present the current version of the tool and we illustrate its application to
two different case studies in the areas of qualitative verification and quantitative evaluation, respectively. 相似文献

A challenging aspect of the next generation detector for rare events searches (i.e. neutrinoless double beta decay and dark matter searches) is the reduction of the background in the region of interest that can mimic the expected signals. In the field of thermal detectors, which have a leading role in rare events searches thanks to their excellent energy resolution and to the wide choice of absorber materials, the background coming from surface contaminations is frequently dominant. A background surface rejection detector is a scintillation-based approach for tagging this type of background. We discuss the innovative application of this technique in non-scintillating thermal detectors. We will report on the performances of the prototype bolometric detector, realized to prove the feasibility of this new technique. 相似文献

Useful information and guidelines are presented for engineers who wish to minimize fracture problems in aluminum engineering structures through better application of materials knowledge and optimum alloy choice. Consideration is given to methods and examples of characterizing fracture resistance of aluminum alloys including interpretations of data addressing basic design approaches. Specific attention is given to trade-offs among properties of strength, fracture toughness, corrosion, stress corrosion cracking, and fatigue in structural aluminum materials. 相似文献

The influence of surface condition on the localized corrosion of 316L stainless steel orthopaedic implants 总被引:2,自引:0,他引:2
The localized corrosion of austenitic stainless steel 316L intended for use as orthopaedic implants is determined as a function of the surface condition and metallurgical state. From the examination of samples exposed to a ferric chloride solution, at both 22 and 37 °C, the independent contribution of crevice and pitting corrosion to localized corrosion is determined. Both forms of localized corrosion occur to a greater extent at the higher temperature. The results indicate that weight loss measurements may not be sufficient to determine the extent of crevice corrosion separately from the influence of pitting corrosion. More importantly, the surface conditions required for the best resistance to crevice or pitting corrosion differ. Electropolished surfaces provide the best resistance to crevice corrosion, while bead blasted surfaces provide the best resistance to pitting corrosion. The implication of this result in terms of the serviceability as orthopaedic implants is discussed. The current results indicate the cold-worked state exhibits improved resistance to pitting corrosion. However, the influence of the metallurgical state could not be separated from a possible compositional effect. © 1999 Kluwer Academic Publishers 相似文献
