Evidence for Carbon Monoxide Insensitive Respiration in the Aerobic Nitrogen Fixing Bacteria Azotobacter vinelandii OP and Xanthobacter autotrophicus GZ 29 (1979)

Abstract In intact cells of the non-gummy Azotobacter vinelandii OP CO-insensitivity of the respiratory activity increased with decreasing dissolved oxygen tension in the bacterial suspension. Upon changing from low to high aeration conditions the CO-sensitive respiration was restored. Measurement of the oxidative activity of small particles of A. vinelandii OP with NADH , ascorbate-DCPIP and ascorbate-TMPD as substrate in the presence and absence of CO indicated that the CO-insensitive site is probably identical with cytochrome a 1 , which preferably is reduced by elec­ trons from ascorbate-DCPIP. Small particles of the gum producing A. vinelandii NCIB 8660 appeared to be more sensitive towards CO with ascorbate DCPIP than the non-gummy A. vinelandii OP. In small particles the CO-insensitive DCPIP oxidase was present irrespective of the dissolved oxygen tension during cell growth. In intact cells, however, CO-insensitivity was only expressed at low dissolved oxygen tension when electrons are directed to cytochrome a 1 /o in the branched re­ spiratory chain. Intact cells of Xanthobacter autotrophicus GZ 29 exhibited a similar CO-insensitive respiration as A. vinelandii OP.
2711. Effectiveness of 13-Valent Pneumococcal Conjugate Vaccine Against Invasive Pneumococcal Disease in Older Adults (2019)

Abstract Background Routine use of 13-valent pneumococcal conjugate vaccine (PCV13) has been recommended for infants since early 2010 and for adults ≥65 years since 2014 when KPNC began routine use of PCV13 in adults. PCV13 vaccine effectiveness (VE) against vaccine-type invasive pneumococcal disease (IPD) has been demonstrated; however, recent surveillance data have been interpreted as showing limited population-level impact of PCV13 on serotype 3 IPD. We estimated PCV13 VE against IPD due to vaccine serotypes at Kaiser Permanente Northern California (KPNC). Methods The study period spanned September 2014 through September 2018. The cohort included KPNC members who were aged ≥65 years with no record of pneumococcal polysaccharide vaccine (PPV23) receipt before age 65 years. We compared IPD cases with KPNC members who were the same age on the date of the positive pneumococcal culture using conditional logistic regression, conditioned on age and date, and controlled for sex, race, KPNC service area and membership history, prior season influenza vaccine receipt, PPV23 receipt after age 65 years, risk factors for IPD, and healthcare utilization. Results From September 2014 to September 2018, PCV13 vaccine coverage among persons ≥65 years old increased from &lt; 1% to 77%. During the same period, there was a total of 245 IPD cases. For a variety of reasons, we did not have serotype results for 57 (23%) IPD cases, which were excluded from the analysis. There were 61 (25%) PCV13-type IPD cases included in the analysis, of which 33 (14%) were serotype 3. PCV13 VE against PCV13-type serotypes was 68.0% (95% CI: 37.7%, 83.6%; P-value &lt; 0.01), and 53.4% (95% CI: −10.0%, 80.3%; P = 0.08) against serotype 3. Conclusion During the first 4 years of PCV13 vaccination implementation in adults ≥65 years of age at KPNC, PCV13 provided significant protection against PCV13-type IPD. Further surveillance will allow for more precise estimation of PCV13 VE on overall and serotype 3 IPD over time. Disclosures All authors: No reported disclosures.
The Mobitex packet-switched radio data system (2003)

This paper is a systems engineering overview of a state-of-art packet switched radio data system-the Mobitex system. RAM Mobile Data operates Mobitex systems in the US and the UK. Mobitex systems are also in operation in Scandinavia and Canada. The system architecture is 'open', which allows any company to enter the wireless data business by providing radio modems and/or application software conforming to the Mobitex interface specification. This paper first outlines the Mobitex network architecture, network protocol, RF system design and the Mobitex 'open' air interface. Finally, the spectral efficiency and response time for transmission of short messages using a wireless packet data network and present day analog cellular systems are compared. It is concluded that a wireless packet data network is superior to analog cellular systems both in terms of spectral efficiency and response time for short data messages.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Heart rate variability in coronary artery disease (1995)

Heart rate variability (HRV) reflects the modulation of cardiac function by autonomic and other physiological systems, and its measurement from ambulatory electrocardiograph (ECG) recordings is a useful method for both clinical and scientific purposes. Heart rate variability can be measured by several linear and non-linear methods, and various methods can give different information on neural and other physiological influences on the heart. Heart rate variability is abnormal in various settings of ischaemic heart disease, and the most important current application of HRV analysis in clinical cardiology is its measurement in postinfarction patients, in whom abnormal HRV indicates an increased risk of cardiac mortality. Future research may expand the clinical utility of HRV measurement to other clinical situations.
Keramiken und Gläser (1993)

Traditionell werden unter dem Begriff Keramik gebrannte Töpfereierzeugnisse aus Ton und anderen Mineralien bezeichnet. Durch Zugabe von Wasser wird aus den Rohmaterialien eine formbare Masse hergestellt, die nach der Gestaltung des Produkts getrocknet und bei 900 bis 1200°C gebrannt wird. Mit zunehmender technischer Bedeutung der Keramiken ist dieser Begriff ausgedehnt worden: Man versteht darunter in der angelsächsischen Literatur sogar alle anorganischen nichtmetallischen Werkstoffe, so daß auch die Halbleiter dazu zählen. In der Tat sind bei der Aufstellung der in optoelektronischen Bauelementen eingesetzten Werkstoffe in Bild 4.3-17 typische Halbleiter (wie GaAs)- und keramische Werkstoffe (wie SnO2 und andere Oxide) enthalten. Auch in den physikalischen Eigenschaften gibt es keine klare Trennung zwischen beiden Werkstoffgruppen. In Tab. 5.1-1 sind technisch wichtige keramische Verbindungen zusammengestellt, Tab. 5.1-2 zeigt die elektrischen Eigenschaften halbleiterähnlicher Keramiken.
Ablation Resolution in Laser Corneal Refractive Surgery: The Dual Fluence Concept of the AMARIS Platform (2010)

Purpose . To evaluate to which extent individual Zernike terms can be corrected. Methods. Ablation time and fidelity was analysed using different fluence levels (range 90–2000 mJ/) and aspheric ablation profiles. With optimal parameters, the extent to which individual Zernike modes can be corrected was evaluated. Results . The range 188–565 mJ/ resulted as optimum fluence level with an optimum proportion range 50%–90% for high fluence. With optimal parameters, it corresponds to 2.4 s/D at 6 mm OZ, with fidelity variance of 53 m RMS, and average ablation error of 0.5 m for each location. Ablation simulation of coma Z[3,1] showed 98,4% accuracy and 98% fit quality; trefoil Z[3,3], 99,9% accuracy and 98% fit quality; spherical aberration Z[4,0], 96,6% accuracy and 97% fit quality; secondary astigmatism Z[4,2], 97,9% accuracy and 98% fit quality. Real ablation on a flat plate of PMMA of coma Z[3,1] showed 96,7% accuracy and 96% fit quality; trefoil Z[3,3], 97,1% accuracy and 96% fit quality; spherical aberration Z[4,0], with 93,9% accuracy and 90% fit quality; secondary astigmatism Z[4,2], with 96,0% accuracy and 96% fit quality. Conclusions . Ablation of aspherical and customised shapes based upon Zernike polynomials up to the the 8th order seems accurate using the dual fluence concept implemented at the AMARIS platform.

Chemisorption of Phosphoric Acid and Surface Characterization of As Passivated AlN Powder Against Hydrolysis (2008)

By simply refluxing a commercial AlN powder in a mixture solution of ethanol, H(3)PO(4), and Al(H(2)PO(4))(3) for 24 h at 80 degrees C, the powder was successfully passivated against hydrolysis. The phosphate layer formed on the surface of AlN powder was found to be quite stable toward protecting the powder from hydrolysis. The efficacy of the coating was established by suspending the treated and the untreated powders in water for 72 h and subsequently characterizing them by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and Raman analysis. The good dispersing behavior of the treated AlN powder in water was confirmed by the low viscosity of an AlN suspension containing 50 vol % solids demonstrating the viability of replacing organic solvents by water in colloidal processing of AlN-based ceramics.
FOOT-AND-MOUTH DISEASE IN EXPERIMENTALLY INFECTED MULE DEER (ODOCOILEUS HEMIONUS) (2019)

The only known outbreak of foot-and-mouth disease (FMD) in wildlife in the US occurred in mule deer (<i>Odocoileus hemionus</i>) in California in 1924-25. There is little recorded information on the pathogenesis and epidemiology of the disease in deer in that outbreak. In this experimental study, we compared the susceptibility of mule deer to FMD virus (FMDV) serotype O to that of cattle (<i>Bos taurus</i>). We also determined the potential for intra- and interspecies transmission of FMDV serotype O in mule deer and cattle, and assessed conventional laboratory tests in their ability to detect FMDV in mule deer. Two mule deer and one steer were each infected by intraepithelial tongue inoculation with 10,000 bovine tongue infective doses of FMDV, strain O1 Manisa. The inoculated steer and deer were kept in the same room with contact animals of both species. Exposed contact animals were moved to rooms with unexposed animals after becoming febrile. All mule deer (<i>n</i>=14) and cattle (<i>n</i>=6) developed clinical signs and lesions consistent with FMDV infection. Deer had a high prevalence of myocarditis and high mortality. Virus was transmitted between mule deer, from cattle to mule deer, and from mule deer to cattle. Virus and antibodies against nonstructural FMDV proteins in mule deer and cattle were detected by conventional laboratory tests. Virus shedding was detected by PCR and virus isolation up to 9 d postexposure in deer.

Electric Field Induced Memory Switching in Thin Films of the Chalcogenide System Ge–As–Se (1971)

A bistable switching has been observed in amorphous films of semiconducting glasses in the system Ge–As–Se in the thickness range 0.3–3 μm. The absence of a heat-induced devitrification and energy production considerations for switching showed that Joule heat produced while switching plays only a minor role in these glasses. Hence, the observed memory action has been attributed to an electric field induced phase transition along a filamentary path in the glass film.
Synthesis and Influenza Virus Inhibitory Activities of Carbosilane Dendrimers Peripherally Functionalized with Hemagglutinin-Binding Peptide (2014)

A series of carbosilane dendrimers uniformly functionalized with hemagglutinin (HA) binding peptide (sialic acid-mimic peptide, Ala-Arg-Leu-Pro-Arg) was systematically synthesized, and their anti-influenza virus activity was evaluated. The carbosilane-based peptide dendrimers, unlike sialylated dendrimers, cannot be digested by virus neuraminidases. The peptide dendrimers exhibited intriguing biological activities depending on the form of their core frame, with a dumbbell-type peptide dendrimer showing particularly strong inhibitory activities against two human influenza viruses, A/PR/8/34 (H1N1) and A/Aichi/2/68 (H3N2). The IC50 values of the dumbbell-type peptide dendrimer for both strains were 0.60 μM, the highest activity among the HA-binding peptide derivatives. The results suggest that a dumbbell-shaped carbosilane dendrimer is the most suitable core scaffold for HA-binding peptide dendrimers.
Association of the Ah receptor with the 90-kDa heat shock protein. (1988)

Partially purified Ah receptor preparations were used to produce a monoclonal antibody, designated as 8D3, that is capable of immunoprecipitating the Ah receptor. Hepa 1c1c7 cytosol was photoaffinity-labeled with [125I]-2-azido-3-iodo-7,8-dibromodibenzo-p-dioxin followed by immunoprecipitation, and the resulting precipitate was applied to a sodium dodecyl sulfate-polyacrylamide electrophoretic gel. These gels were stained with Coomassie Blue and revealed the presence of a major immunoprecipitated 90-kDa protein, and after autoradiography a radiolabeled 95-kDa protein (Ah receptor) was detected. The 90-kDa protein was determined to be the 90-kDa heat shock protein (HSP90) by western blot analysis using an antibody (AC88) previously shown to be specific for HSP90. An increase in the sedimentation of the Ah receptor on sucrose density gradients was seen upon addition of monoclonal antibody 8D3 to Hepa 1c1c7 cytosol. Monoclonal antibody 8D3 immunoprecipitates the Ah receptor from Hepa 1 cells (murine), HeLa cells (human), and rat liver cytosolic extracts, indicating that the Ah receptor is complexed with HSP90 in several mammalian species tested. These results illustrate another physicochemical property that the supergene family of soluble steroid receptors and the Ah receptor have in common.

Electron microscopic study of deformation in polyethylene (1969)

Abstract Thin films of polyethylene prepared from blends of fractionated polymer and a linear hydrocarbon ( n ‐C 32 H 66 ) have been used to study the role of intercrystalline links in the deformation of semicrystalline polymer under uniaxial stress. These links have been found to be strong and virtually inextensible elements of the structure. It is shown that they are firmly attached to the chain‐folded lamellar crystals they bridge (both within the same spherulite and across boundaries between adjacent spherulites) and that, by concentrating applied stress, they commonly induce these lamellae to begin yielding in regions close to their points of attachment. Where there are many closely spaced links the stress is distributed fairly evenly, and drawing is relatively smooth and uniform. With more sparsely distributed links, however, stresses tend to be concentrated at widely separated points; deformation then tends to be severe and highly localized, often resulting in failure of the material upon drawing. There are indications that stress is also transmitted between chain‐folded lamellae in ways other than by intercrystalline links. One such way is by means of chain ends and molecular loops that emerge from the surfaces of these crystals and are embedded in interlamellar material. Experiments in which the deformed films were subsequently heated confirm earlier conclusions that extended chains in drawn polymer may undergo refolding during annealing.
Analysis of Novel Hybrid-Magnet-Circuit Variable Flux Memory Machines with Different Magnet Arrangements (2019)

This paper presents two novel hybrid-magnetic-circuit variable flux memory machines (HMC-VFMMs) with different permanent magnet (PM) configurations. The proposed HMC-VFMMs are both characterized by a combination of series and parallel circuit topologies, but with different positions of series and parallel PM branches. The proposed HMC design can combine the merits of wide flux adjustment range in parallel structure and excellent unintentional demagnetization (UD) withstand capability in series structure. The topologies, features and working principles of the proposed HMC-VFMMs with different magnet arrangements are introduced, respectively. The magnetic circuit model is utilized to reveal the underlying working mechanism and performance metrics of the proposed HMC-VFMMs having different PM types. The electromagnetic characteristics of the HMC-VFMMs having radially-magnetized (RM) and circumferentially-magnetized (CM) LCF PM types are evaluated and compared by the finite-element (FE) method. The experiments on a 21-slot/4-pole prototype with RM-structure are carried out to validate the FE analyses.
Boosting tower performance by more than a trickle (1985)

Improved dumped-and structured-packing designs for absorption and distillation columns has done much to encourage research in liquid distribution systems. The reason for this is that conventional distributors of the trough, orifice or pipe variety don't function well with the new packings. This article describes how different types of distributors operate, how many distribution points are needed for various tower diameters and packings, and how liquid distribution is affected by different kinds of packings. Most researchers agree that poor liquid distribution in packed columns causes a severe reduction in column efficiency.
Influence of β-radiation sterilisation in properties of new chitosan/soybean protein isolate membranes for guided bone regeneration (2004)

Novel chitosan (cts) and soybean protein isolate (SI) blended membranes were prepared. These membranes were produced by solvent casting. Besides combining the advantages of both materials, cts/SI membranes exhibit a biphasic structure that will eventually originate in situ porous formation, through a two-step degradation mechanism. In this particular work the effect of β-radiation over the properties of these membranes was evaluated. β-radiation sterilisation was performed at three different doses (25, 50 and 100 kGy) and eventual surface chemical changes were evaluated by Fourier transformed infrared – with attenuated total reflection and contact angle measurements. Moreover, eventual bulk properties changes due to β-radiation were assessed by means of mechanical tensile tests and water uptake measurements. In general, no substantial changes were detected on the studied properties, with the exception of the surface energy that was found to be slightly increased for higher applied doses.
Poliovirus tropism and attenuation are determined after internal ribosome entry (2004)

Poliovirus replication is limited to a few organs, including the brain and spinal cord. This restricted tropism may be a consequence of organ-specific differences in translation initiation by the poliovirus internal ribosome entry site (IRES). A C-to-U mutation at base 472 in the IRES of the Sabin type 3 poliovirus vaccine strain, known to attenuate neurovirulence, may further restrict tropism by eliminating viral replication in the CNS. To determine the relationship between IRES-mediated translation and poliovirus tropism, recombinant human adenoviruses were used to express bicistronic mRNAs in murine organs. The IRESs of poliovirus, the cardiotropic coxsackievirus B3 (CVB3), and the hepatotropic hepatitis C virus (HCV) mediate translation in many organs, including those that do not support viral replication. A translation defect associated with the Sabin type 3 IRES was observed in all organs examined. Poliovirus type 1 and recombinant polioviruses dependent on the IRES of CVB3 or HCV replicate in the CNS of mice and cause paralysis. Although the type 3 Sabin strain is an effective vaccine, polioviruses with a U at base 472 of the IRES cause paralysis in newborn mice. Tropism of wild-type and vaccine strains of poliovirus is therefore determined after internal ribosome entry.
Production of Chimeric Mice from Cryopreserved Blastocysts. (1998)

Mouse blastocysts derived from in vivo fertilization were cryopreserved by a simple vitrification method. Most of the cryopreserved blastocysts survived while demonstrating a normal morphology after warming (88.1%). The rate of cryopreserved blastocysts which developed to term as normal young was 56.8%, and chimeric mice were also produced from cryopreserved blastocysts injected with ES cells. As a result, 3.4% of the injected embryos developed to term as germ line chimeric mice.
