Autoignition Behavior of Petroleum-Based and Hydroprocessed Renewable Jet Fuel Blends in a Rapid Compression Machine (2013)

A rapid compression machine (RCM) is used to study the autoignition characteristics of JP-8 and JP-5 blended in 50-50 mixtures by volume with their respective camelina-derived hydroprocessed renewable jet (HRJ) fuel at low temperature conditions. The tests employ the direct test chamber (DTC) charge preparation method which allows for high reproducibility of measurements. Ignition delay measurements are compared between the conventional military jet fuels, HRJ fuels, and the 50-50 blends. Measurements are made at compressed pressures of 5, 10, and 20 bar at an equivalence ratio of 1.0 and compressed temperatures between 625 K and 710 K. Additional ignition delay measurements are reported at reduced equivalence ratios of 0.5 and 0.25 at a compressed pressure of 20 bar and temperatures between 635 K and 720 K.
Oxidative‐Alkaline Leaching of Washed 241‐SY‐102 and 241‐SX‐101 Tank Sludges and Its Impact on Immobilized High‐Level Waste (2006)

Abstract This report describes work designed to evaluate the effectiveness of alkaline permanganate contacts at selectively removing chromium from the Hanford tank sludges 241‐SY‐102 and 241‐SX‐101. The key variables examined in this study, as compared to contact with the standard conditions of stoichiometric permanganate in 3 M hydroxide at elevated temperature, were: a) excess permanganate and hydroxide at elevated temperature, b) sequential elevated temperature 3 M hydroxide leach combined with either a room temperature permanganate contact or an elevated temperature permanganate contact at 0.25 M hydroxide. It was determined that sequential permanganate and caustic leaching can provide as effective removal of Cr as the combined high hydroxide permanganate contact at elevated temperature while minimizing concomitant Pu dissolution.
Dynamic Principal Component Analysis Using Integral Transforms (1998)

The paper describes an approach to dynamic multivariate analysis in which principal component analysis (PCA) is combined with integral transform techniques. The aim was to detect correlations when process dynamics cause lags or time delays. The techniques give a signature that characterises the correlated measurements. Tools for Fourier and wavelet PCA have been developed and tested. They have been demonstrated through the analysis of acoustic signals captured in a pilot plant using a multichannel acoustic instrument purpose-built for the project. A highlight of the work was the demonstration using the acoustic emissions from a stirred tank reactor of an instance where dynamic PCA in the time domain failed and Fourier PCA succeeded in showing that three acoustic channels were correlated, having a spectral signature at several frequencies in the low audio range.
Resonant tunneling action in ZnO/Zn/sub 0.8/Mg/sub 0.2/O double barrier devices (2002)

A ZnO/Zn/sub 0.8/Mg/sub 0.20/O double barrier resonant tunneling device (DBRTD) is reported here for the first time. The structures consist of a ZnO quantum well, with thicknesses of 6 nm, 8 nm, and 50 nm, placed between two Zn/sub 0.8/Mg/sub 0.2/O barriers, with a thickness of 7 nm. The structures were grown by pulsed laser deposition (PLD) on c-cut sapphire substrates. Negative differential resistance (NDR) peaks were obtained at room temperature and at 200 K. The ground states for the wells were evaluated from photoluminescence spectroscopy measurements, and found to be 266.3 meV and 238.8 meV for the 6 nm and 8 nm well respectively. The FWHM of the photoluminescence peaks was found to be 5.3 and 5.6 meV at 77 K, for the 6 nm and 8 run wells respectively, indicating high quality heterointerfaces.
Mechanical properties of PHB-Bagasse composites (2006)

Biodegradable composites produced from natural fibres and biodegradable polymers are an alternative to synthetic plastics, The optimisation of the mechanical properties for bagasse-poly(3- hydroxybutyrate) (PHB ) composite was performed and aspects such as fibre-matrix ratios and fibre surface treatment were studied, The mechanical properties of the composite were determined through flexural testing and the modes of failure studied by means of SEM.
Ethanol, Morphine and Barbiturate Alter the Hemodynamic and Cerebral Response to Cocaine in Newborn Pigs (1995)

Newborns delivered to cocaine-abusing mothers are often exposed to other concurrently consumed illicit drugs, which may alter the hemodynamic and cerebral response to cocaine. This study examined the interaction of ethanol, morphine or barbiturate with cocaine on mean arterial pressure (MAP), cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) in newborn pigs. CBF, CMRO2 and cerebral O2 extraction (CEO2) were measured before and 4 and 10 min after cocaine (1.5 mg/kg i.v.) was administered in piglets that were awake, or pretreated with morphine, ethanol or pentobarbital. In awake piglets, cocaine increased CMRO2 and CEO2 while it had no significant effect on CBF. Conversely, in morphine- and ethanol-pretreated piglets, cocaine decreased CMRO2, decreased CBF and had not effect on CEO2. In awake piglets, cocaine increased MAP, whereas in morphine- or ethanol-pretreated piglets, cocaine decreased MAP. In the pentobarbital group, cocaine had no effect. These data demonstrate that other drugs of abuse alter the hemodynamic and cerebral effects of cocaine in the immature animal and may contribute to the central nervous system abnormalities in 'crack babies'.

Penetrating Gluteal Injuries (1982)

A review of 60 patients admitted with penetrating gluteal trauma during a 4-year period supports the concept that these wounds constitute a distinct group of injuries with a potential for serious, or even lethal, damage to a spectrum of organ systems. A plan of evaluation and management is presented. A high index of suspicion, repeated careful evaluation, and aggressive operative management of these injuries are mandatory to achieve a low morbidity and mortality.
T-maze spontaneous alternation rate is decreased in S100!b transgenic mice. (1994)

S100 beta, a calcium-binding brain specific protein, may affect both brain development and hippocampal long-term potentiation. S100 beta levels are elevated in Down syndrome (DS), and the gene for S100 beta is located on chromosome 21, which is duplicated in DS. To test the hypothesis that, elevated levels of S100 beta cause behavioral alterations in a mammalian system, 3 transgenic mouse lines with multiple copies of the human gene for S100 beta were derived and behaviorally tested. The spontaneous alteration behavior of transgenic and normal littermate mice were compared in a T maze during a 15-trial test. The overall alteration rate was found to be significantly decreased in the transgenic mice compared with their normal littermates. The S100 beta transgenic mouse model offers one of the first opportunities to investigate the relation between overexpression of a human chromosome 21 gene product and abnormal behavior and brain function.
Association between orbital fracture location and ocular injury: a retrospective study. (1998)

Severe injuries were associated with orbital apex fractures (p = 0.00001), with lateral wall fractures (p < 0.04), and with Le Fort Type III fractures (p < 0.02). Moderate injuries were associated with isolated orbital floor fractures (p < 0.01). Apex, lateral wall, and Le Fort Type III fractures have a greater association with severe ocular injuries than other fracture types.

Synthesis and applications of highly stable non-symmetrical heterocyclic carbenium ions (2008)

Les carbocations sont généralement des intermédiaires réactionnnels à très courte durée de vie, cherchant à redonner "in fine" une molécule stable. Durant plusieurs décennies, l'étude des carbocations a d'ailleurs été principalement vouée à l'isolation et à la caractérisation de telles espèces. Il existe cependant une autre classe de carbocations dite (hautement) stabilisée. Cette dernière est constituée d'espèces carbocationiques très stables pouvant même être manipulées dans des conditions de nucléophilies et basicités extrêmes. Ces "carbocations" sont aussi réputés, notamment pour leurs propriétés physico chimiques, mais également et surtout pour leurs innombrables applications. Plus particulièrement, récemment une nouvelle variété de carbocations hétérocycliques hautement stabilisés à ponts oxygénés et azotés a été publiée: les Azatriangulénium. Le but de cette thèse a donc été non seulement d'introduire d'autres atomes que l'oxygène et l'azote à la périphérie de ces ions, mais aussi de trouver toute une multitude d'applications très intéressantes avec ces derniers.
Insulin Release from a Bioartificial Pancreas Using a Mesh Reinforced Polyvinyl Alcohol Hydrogel Tube (1993)

Islet transplantation with a bioartificial pancreas is a potential alternative to whole pancreas transplantation. The authors constructed a bioartificial pancreas using mesh reinforced polyvinyl alcohol hydrogel tubes (MRPT), in an attempt to clarify the in vitro responsiveness to glucose of islets seeded in the MRPT. When the MRPT were perfused in a small chamber with buffer containing 3.3 mmol or 16.7 mmol glucose, insulin release from the MRPT began to increase at 9 ± 3 min, reaching a plateau at approximately 40 min after the glucose concentration in the perfusate increased from 3.3 to 16.7 mmol. When MRPT seeded with islets were subjected to static incubation in buffer containing 3.3 mmol or 16.7 mmol glucose, insulin release from the MRPT remained elevated for 3 hr of high glucose stimulation, the amount of secreted insulin depending upon the number of islets seeded. Although pre incubation of semipermeable membranes in culture medium containing fetal bovine serum prior to seeding with islets has recently been reported to improve insulin release, the authors found that such pre treatment of the MRPT did not have a beneficial effect. Their in vitro findings in this study suggest that the bioartificial pancreas using MRPT could be a promising therapeutic approach to human diabetes mellitus.
Structure determination of flufenamic acid cocrystals from laboratory X-ray powder diffraction data (2010)

Hans Hinterreiter was a Swiss painter, belonging to the Constructivist movement, who spent most of his life in Ibiza, Spain. Since 1930 he occupied himself with the laws of form and colour. Parallel to Escher, he discovered laws of coloured symmetry before crystallographers started working on them (more about it in [1]). After a period of experimentation with plane groups of symmetry, he moved to a more complex level of geometric abstract art by applying non-linear transformations to the plane-group patterns. His goal was to achieve a more dynamic rendition of the patterns used. My poster illustrates four different cases of this process, starting always with a plane-group pattern and showing both the application of non-linear transformations and coloured symmetry.
Changes in ventricular–arterial coupling during decongestive therapy in acute heart failure (2014)

An early improvement in ventricular-arterial coupling was observed after diuretic-related decongestive therapy in ADHF patients and was related to a decrease in effective arterial elastance rather than to change in LV contractility.

Utero-tubal Embryo Transfer and Vasectomy in the Mouse Model (2014)

The transfer of preimplantation embryos to a surrogate female is a required step for the production of genetically modified mice or to study the effects of epigenetic alterations originated during preimplantation development on subsequent fetal development and adult health. The use of an effective and consistent embryo transfer technique is crucial to enhance the generation of genetically modified animals and to determine the effect of different treatments on implantation rates and survival to term. Embryos at the blastocyst stage are usually transferred by uterine transfer, performing a puncture in the uterine wall to introduce the embryo manipulation pipette. The orifice performed in the uterus does not close after the pipette has been withdrawn, and the embryos can outflow to the abdominal cavity due to the positive pressure of the uterus. The puncture can also produce a hemorrhage that impairs implantation, blocks the transfer pipette and may affect embryo development, especially when embryos without zona are transferred. Consequently, this technique often results in very variable and overall low embryo survival rates. Avoiding these negative effects, utero-tubal embryo transfer take advantage of the utero-tubal junction as a natural barrier that impedes embryo outflow and avoid the puncture of the uterine wall. Vasectomized males are required for obtaining pseudopregnant recipients. A technique to perform vasectomy is described as a complement to the utero-tubal embryo transfer.
The water–carbon monoxide dimer: new infrared spectra, <i>ab initio</i> rovibrational energy level calculations, and an interesting in-termolecular mode (2019)

Bound state rovibrational energy level calculations using a high-level intermolecular potential surface are reported for H2O-CO and D2O-CO. They predict the ground K = 1 levels to lie about 20 (12) cm-1 above K = 0 for H2O-CO (D2O-CO) in good agreement with past experiments. But the first excited K = 1 levels are predicted to lie about 3 cm-1 below their K = 0 counterparts in both cases. Line strength calculations also indicate that mid-infrared transitions from the K = 0 ground state to this seemingly anomalous excited K = 1 state should be observable. These predictions are strikingly verified by new spectroscopic measurements covering the C-O stretch region around 2200 cm-1 for H2O-CO, D2O-CO, and HOD-CO, and the O-D stretch region around 2700 cm-1 for D2O-CO, HOD-CO, and DOH-CO. The experiments probe a pulsed supersonic slit jet expansion using tunable infrared quantum cascade laser or optical parametric oscillator sources. Discrete perturbations in the O-D stretch region give an experimental lower limit to the binding energy D0 of about 340 cm-1 for D2O-CO, as compared to our calculated value of 368 cm-1. Wavefunction plots are presented to help understand the intermolecular dynamics of H2O-CO. Coriolis interactions are invoked to explain the seemingly anomalous energies of the first excited K = 1 levels.
Strontium Isotopic Composition in Individual Circumstellar Silicon Carbide Grains: A Record of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi mathvariant="italic">s</mml:mi></mml:math>-Process Nucleosynthesis (1998)

Twenty six individual circumstellar SiC grains extracted from the Murchison meteorite were analyzed for their strontium isotopic compositions by resonant ionization mass spectrometry. Large abundance deficits were found for the $p$-process isotope ${}^{84}\mathrm{Sr}$. The measured grains had ${}^{87}\mathrm{Sr}{/}^{86}\mathrm{Sr}$ ratios indistinguishable from the primordial solar value, but several grains differed in their ${}^{88}\mathrm{Sr}{/}^{86}\mathrm{Sr}$ ratios as a consequence of the branch point at ${}^{85}\mathrm{Kr}$. The Sr isotopic data are consistent with $s$-process nucleosynthesis at moderate neutron densities.
Alfacalcidol increases cancellous bone in low turnover, fatty marrow sites in aged, orchidectomized rats. (2009)

The objectives of this study were to determine the responses of cancellous bone in the distal tibial metaphysis (DTM), a low turnover, fatty (yellow) marrow site, to sham-aged, orchidectomy (ORX) and alfacalcidol treatment in sham-aged and ORX rats. Eighteen-month-old male sham and ORX rats were treated with 0.1 and 0.2 microg/kg alfacalcidol 5 days/wk p.o. for 12 weeks, double fluorescent labeled, and the DTM were processed for bone histomorphometry analyses. The current study found the DTM in sham-aged male rats were resistant to age-related and ORX-induced cancellous bone loss and alfacalcidol-induced bone gain, findings that differ from that in the proximal tibial metaphysis (PTM) and lumbar vertebral body (LVB), two high turnover, red marrow bone sites. However, alfacalcidol treatment increased DTM bone mass in ORX rats where bone turnover was elevated by androgen deficiency. These results in concert with the previously positive findings in red marrow bone sites following alfacalcidol treatment suggest that alfacalcidol is more effective in increasing cancellous bone mass in the skeletal sites with higher bone turnover.
[Exertional heatstroke]. (2012)

Exertional heatstroke is defined by an increase of core body temperature above 40 degrees C and neurological symptoms in association with exercise. It is related to excessive heat production, which overwhelms the endogenous mechanisms of thermoregulation. It is observed during intense physical activity in a hot and humid environment, most commonly in untrained subjects poorly adapted to such conditions. Clinical manifestations of exertional heatstroke are related to the induction of a systemic inflammatory response and a disseminated intravascular coagulation triggered by heat stress, which may lead to multiorgan dysfunction and death. Early management through rapid cooling is mandatory to prevent the devastating consequences of exertional heatstroke.
Systematic Evaluation of Graft-Versus-Leukemia Immunity of AML-Reactive T Cell Products Using Humanized NOD/SCID/IL2R γcNULL Mice (2012)

We have recently established an immunodeficient NOD/SCID/IL2Rγcnull (NSG) mouse model that allows the reliable engraftment of primary human acute myeloid leukemia (AML) blasts, particularly those with FLT3-ITD mutations. We now use these mice as a platform to evaluate the graft-versus-leukemia (GvL) effect of human leukemia-reactive T cells in vivo. To systematically optimize essential parameters for survival and effector function of human T cells in NSG mice, large numbers of AML-reactive cytotoxic T lymphocytes (CTL) were generated in vitro by stimulation of healthy donor CD8+ T cells with FLT3-ITD+ AML blasts in either single HLA-class I-mismatched or HLA-matched situations.
A 660-/spl mu/W 50-Mops 1-V DSP for a hearing aid chip set (2000)

This article presents the flow and techniques used to design a low-power digital signal processor chip used in a hearing aid system implementing multiband compression in 20 bands, pattern recognition, adaptive filtering, and finescale noise cancellation. The pad limited 20 mm/sup 2/ chip contains 1.3 M transistors and operates at 2.5 MHz under 1.05-V supply voltage. Under these conditions, the DSP consumes 660 /spl mu/W and performs 50 million 22-bit operations per second, therefore achieving 0.013 mW/Mops (milli-watts per million operations), which is a factor of seven better than prior results achieved in this field. The chip has been manufactured using a 0.25-/spl mu/m 5-metal 1-poly process with normal threshold voltages. This low-power application-specific integrated circuit (ASIC) relies on an automated algorithm to silicon flow, low-voltage operation, massive clock gating, LP/LV libraries, and low-power-oriented architectural choices.
Molecular mechanisms that control interstitial fibrosis in the pressure-overloaded heart (2010)

When considering the pathological steps in the progression from cardiac overload towards the full clinical syndrome of heart failure, it is becoming increasingly clear that the extracellular matrix (ECM) is an important determinant in this process. Chronic pressure overload induces a number of structural alterations, not only hypertrophy of cardiomyocytes but also an increase in ECM proteins in the interstitium and perivascular regions of the myocardium. When this culminates in excessive fibrosis, myocardial compliance decreases and electrical conduction is affected. Altogether, fibrosis is associated with an increased risk of ventricular dysfunction and arrhythmias. Consequently, anti-fibrotic strategies are increasingly recognized as a promising approach in the prevention and treatment of heart failure. Thus, dissecting the molecular mechanisms underlying the development of cardiac fibrosis is of great scientific and therapeutic interest. In this review, we provide an overview of the available evidence supporting the general idea that fibrosis plays a causal role in deteriorating cardiac function. Next, we will delineate the signalling pathways importantly governed by transforming growth factor β (TGFβ) in the control of cardiac fibrosis. Finally, we will discuss the recent discovery that miRNAs importantly regulate cardiac fibrosis.
