Context: Timely testing of women in labor with undocumented human immunodeficiency virus (HIV) status could enable immediate provision of antiretroviral ***: To determine the feasibility and acceptance of rapid HIV testing among women in labor and to assess rapid HIV assay performance. design, Setting, and Patients: The Mother Infant Rapid Intervention At delivery(MIRIAd) study implemented 24-hour counseling and voluntary rapid HIV testing for women in labor at 16 US hospitals from November 16, 2001, through November 15, 2003. A rapid HIV-1 antibody test for whole blood was used. Main Outcome Measures: Acceptance of HIV testing; sensitivity, specificity, and predictive value of the rapid test; time from blood collection to patient notification of results. Results: There were 91 707 visits to thelabor and delivery units in the study, 7381 of which were by eligible women without documentation of HIV *** these, 5744 (78%) women were approached for rapid HIV testing and 4849 (84%) consented. HIV-1 test results were positive for 34 women (prevalence=7/1000). Sensitivity and specificity of the rapid test were 100%and 99.9%, respectively; positive predictive value was 90%compared with 76%for enzyme immunoassay (EIA). Factors independently associated with higher test acceptance included younger age, being black or Hispanic,gestational age less than 32 weeks, and having had no prenatal care. Lower acceptance was associated with being admitted between 4 PM and midnight, particularly on Friday nights, but this may be explained in part by fewer available personnel. Median time from blood collection to patient notification of result was 66 minutes(interquartile range, 45-120 minutes), compared with 28 hours for EIA (P d HIV testingis feasible and delivers accurate and timely test results for women in labor.

OBjECTIVE: To describe the pregnancy rates among women whose husbands underwent vasectomy. METHOdS: Between 1985 and 1987, 573 women aged 18-44 years whose husbands underwent vasectomy in medical centers in 5 U.S. cities were enrolled in the U.S. Collaborative Review of Sterilization, a prospective cohort study of male and female sterilization. Women were interviewed by telephone at 1, 2, 3, and 5 years after their husbands underwent vasectomy. RESULTS: Among the 540 eligible women at risk for pregnancy, there were 6 pregnancies occurring from 6 to 72 weeks after vasectomy. The cumulative probability of failure per 1,000 procedures (95%confidence interval) was 9.4 (1.2, 17.5) 1 year after vasectomy and 11.3 (2.3, 20.3) at years 2, 3, and 5. CONCLUSION: Couples considering vasectomy should be counseled about the small, but real, risk of pregnancy following the procedure and that men are not sterile immediately after vasectomy.

RELATIONSHIP BETWEEN INFRAREd RAdIATION ANd CRYSTAL STRUCTURE IN Fe-Mn-Co-Cu-O SPINELS

Acta Metallurgica Sinica(English Letters) 2008年第1期21卷 15-20页

作者： Y. Zhang d.j. Wen School of Material Engineering Soochow University Suzhou 215021 China

Ni^3＋ and Cr^3＋ doped Fe-Mn-Co-Cu-O spinels have been prepared by solid phase sintering. The valence states and distribution of transition ions in the spinel crystals are inferred by the consideration of thermodynamic principle and crystalline field theory. The mierostructure and performance of those are studied by X-ray diffraction （XRd）, Fourier transform infrared （FT-IR）, and IRE-2 infrared radiant instrument. Ni3＋ and Cr3＋ occupy the vacancies or substitute the other ions in the spinel structures and form diverse spinel structures, which exhibit infrared integral emissivities of 0.93 in the whole band, and 0. 94 in the band within 14-25μm too. The content of Fe2O3 and MnO2 in the spinel crystals changes, maybe it induces infrared radiativity of spinels differently.

Atomistic Simulation of the Orientation-dependent Plastic deformation Mechanisms of Iron Nanopillars

引用

journal of Materials Science & Technology 2012年第2期28卷 164-168页

作者： Y. Zhang d.j. Yu K.M. Wang Anshan-Normal University 43 Pingan Street Anshanll4005 China University of Science and Technology LiaoNing Anshanll4051 China

Tensile tests were performed on iron nanopillars oriented along [001] and [110] directions at a constant temperature of 300 K through molecular dynamics simulations with an embedded-atom interatomic potential for iron. The nanopillars were stretched until yielding to investigate the onset of their plastic deformation behaviors. Yielding was found to occur through two different mechanisms for [001] and [110] tensions. In the former case, plastic deformation is initiated by dislocation nucleation at the edges of the nanopillar, whereas in the latter case by phase transformation inside the nanopillar. The details during the onset of plastic deformation under the two different orientations were analyzed. The varying mechanisms during plastic deformation initiation are bound to influence the mechanical behavior of such nanoscale materials, especially those strongly textured.

Multilayer Cu-Co film has been produced from a single bath by the method of pulse electrodeposition. Its structure and some magnetic properties were analysed by TEM,AES, XRd and VSM. The results indicated that the film was layed structure, consisted of alternating pure copper and copper-cobalt alloy layers. The results have shown the possibility of producing multilayer films with perpendicular magnetic anisotropy byelectrodeposition.

Accuracy details in realistic CFd modeling of an industrial centrifugal pump in direct and reverse modes

Numerical computation of the flowfield inside a pump is herein used as a numerical laboratory, subject to the limitations of modeling assumptions and to experimental verification. A numerical computation of the flow inside a real industrial centrifugal pump is performed that includes a very sophisticated geometry. Conversely to other computations, in this test case no simplification of the geometry was introduced. Numerical computations are obtained using Spalart-Allmaras turbulence model. A detailed analysis of the turbulent flowstructure is performed for the design point and two off design conditions. Additional computations were performed in order to compare the numerical and experimental pump characteristics; these were obtained under normalized testing conditions. Further computations are presented for the pump working in reverse turbine mode (PAT). detailed analyses of the flow allow a comparison of the internal flow losses when the pump is operating in direct and reverse mode. This is also useful to help in the selection of an adequate pump geometry that can work in both modes with best efficiency.

Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).
