    Cryogenic, all-sapphire, Fabry–Perot optical frequency reference (1995)

    Notes: This paper presents a design for a Fabry–Perot optical frequency reference resonator which utilizes the high dimensional stability of cryogenically cooled sapphire. We show that cryogenic sapphire cavities can achieve substantial improvements in frequency stability compared with room-temperature cavities. The design of a laser stabilization system based on such a resonator is discussed. Estimates of fundamental and practical limitations on the frequency stability of such a system suggest that a fractional frequency stability of 10−16 over integration times from 10 to 104 s is possible. The fundamental limits to stability from quantum shot noise, radiation pressure fluctuations, and thermal noise are overwhelmed by practical limits which arise due to mechanical, thermal, and optical effects. © 1995 American Institute of Physics.

    Fetal pathology in intrauterine death due to parvovirus B19 infection (1996)

    Notes: Objective To study the pathological features of fetuses dying because of parvovirus B19 infection, with particular reference to the presence of hydrops; to assess the usefulness of immunochemistry as a screening method for the detection of parvovirus infection at post-mortem examination.Design Review of clinical, sonographic, serological and pathological data; immunohistochemical staining of post-mortem tissue.Sample Cases of intrauterine fetal death occurring during the 18-month period January 1993 to June 1994 inclusive, referred for post-mortem examination to the Pathology Department, Royal Victoria Infirmary, Newcastle upon Tyne.Results Eleven cases of fetal death due to parvovirus infection were identified. Seven fetuses were less than 18-week size. Three fetuses showed conspicuous hydropic change. One of the 11 cases was detected for the first time by retrospective immunochemical screening. Of cases originating from the Newcastle district, parvovirus infection was responsible for about 10YO of all non-malformed fetal deaths occurring between 10 and 24 weeks of gestation referred for pathological examination.Conclusions During the period of study, parvovirus infection was a relatively common cause of mid-trimester fetal death. Many fetuses dying because of this infection are not noticeably hydropic, and the possibility of parvovirus infection should be considered in any case of intrauterine fetal death. Immunochemistry can be used to confirm the histopathological diagnosis, and may be of particular help where there is advanced autolysis; immunohistochemical screening may detect occasional cases not initially identified by examination of routinely stained tissue sections.

    THE NATURE OF THE TWO PROTEINS OF BRAIN SPECIFIC ANTIGEN 14-3-2 (1978)

    Notes: The three isoenzymes of rat brain enolase (2-phospho d-glycerate hydrolase EC 4.2.1.11.) χχ, χγ and γγ were separated by ion-exchange chromatography and were tested for reaction with an antiserum against brain specific antigen 14-3-2. This monospecific antiserum affects the enolase activity of only the χγ and γγ isoenzymes.Immunoelectrophoretic experiments show that the two proteins which react as 14-3-2 both contain γ enolase subunits, and one of these also contains χ enolase subunits.It is concluded that the 14-3-2 antigen and the γ enolase subunit are identical, and that the two proteins which react immunologically as 14-3-2 are the χγ and γγ enolase isoenzymes.

    Development of the third generation electron cyclotron resonance ion source : Proceedings of the 7th international conference on ion sources (1998)

    Notes: The LBNL third generation electron cyclotron resonance (ECR) ion source has progressed from a concept to the fabrication of a full scale prototype superconducting magnet structure. This new ECR ion source will combine the recent ECR ion source techniques that significantly enhance the production of high charge state ions. The design includes a plasma chamber made from aluminum to provide additional cold electrons, three separate microwave feeds to allow multiple-frequency plasma heating (at 10, 14, and 18 GHz or at 6, 10, and 14 GHz) and very high magnetic mirror fields. The design calls for mirror fields of 4 T at injection and 3 T at extraction and for a radial field strength at the wall of 2.4 T. The prototype superconducting magnet structure which consists of three solenoid coils and six race track coils with iron poles forming the sextupole has been tested in a vertical Dewar. After training, the sextupole magnet reached 105% of its design current with the solenoids off. With the solenoids operating at approximately 70% of their full design field, the sextupole coils operated at 95% of the design value which corresponds to a sextupole field strength at the plasma wall of more than 2.1 T. © 1998 American Institute of Physics.

    Superior free-standing meshes for use as infrared Fabry–Perot elements made with a new photolithographic technique (1988)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 59 (1988), S. 1094-1097

    Notes: A photolithographic technique for fabrication of very smooth and highly uniform metallic, free-standing, inductive meshes, is described. The fabrication process was developed in order to produce highly reflective, low-loss Fabry–Perot étalon elements for use in the infrared spectral region. The measured rms smoothness of the grids is typically ≤30 A(ring). Because of their nickel core, the mechanical strength of the grids is such that they can be easily stretched flat on stainless-steel rings.

    Control of menorrhagia by the cyclo-oxygenase inhibitors naproxen sodium and mefenamic acid (1987)

    Notes: Thirty-five patients with menorrhagia were treated in a double-blind crossover study with naproxen sodium and mefenamic acid after measurement of their blood loss during control menstrual cycles. Treatment with these compounds reduced the excessive bleeding by an average of 46 and 47% respectively. Drugs in the prostaglandin synthetase inhibitor group are considered to have an important place in the treatment of menorrhagia.

    Notes: Abstract. Statistical analysis of monitoring data is becoming a necessary part of many ground- and surface-water quality management activities. To meet this need a statistical software package for microcomputers called WQStat II has been designed and produced specifically for water quality applications. The software provides tools for data management, summarizing data characteristics, analyzing trends, comparing medians of two or more groups of data, and evaluating excursions or standards violations. To minimize problems associated with nonnormal data and nondetects, WQStat relies primarily on graphical and nonparametric approaches.
