Effect of fuel sootiness on the heat fluxes to the walls in enclosure fires (2006)

Even though considerable work has been performed regarding gas temperatures and burning rates in enclosures, scant information is available for the heat fluxes and their distributions on the walls of an enclosure. These heat fluxes are necessary input for determining the thermal response and performance of the wall materials and especially glazing. The heat fluxes on the wall of an experimental enclosure were deduced from the temperatures in several thermally thin small steel plates (25.4 mm×25.4 mm×3 mm) and in the insulation surrounding the steel plates. In addition, the mass loss rate and gas temperatures near these heat flux gauges were measured. The experimental enclosure was the 1/3 linear scale of the ISO room corner test having six openings and three square-pans of variable size burning Methanol, IMS (Industrial Methylated Spirits) and Toluene at the corner and in the center of the enclosure. By choosing fuels with an increased degree of sootiness it was found that the heat fluxes do not depend only on the gas temperature, as claimed before for heat fluxes on the floor, but also on the magnitude of the heat release rate and the fuel sootiness. Moreover, comparison of the heat fluxes for methanol, IMS and toluene allow the separation of convective from radiative heat fluxes owing to hot gases (and the enclosure walls) and from the radiative heat fluxes from the fire plume.
Accurate determination of selenium in blood serum by isotope dilution analysis using inductively coupled plasma collision cell mass spectrometry with xenon as collision gas (2006)

A method for accurate selenium determination in blood serum by isotope dilution analysis (IDA) was developed. Selenium was determined by ICP octopole reaction system MS using xenon as the collision gas (130–160 μL min−1) in order to eliminate polyatomic interferences from argon, chlorine, phosphorus and bromine. The detection limit was 3.3 μg L−1, which was higher than with hydrogen (0.4 μg L−1) but sufficiently sensitive to determine selenium in serum. Selenium isotope ratios could be determined precisely and accurately without any mathematical interference corrections, enabling IDA at the 80Se/76Se ratio. In contrast, these corrections were necessary when hydrogen was used as the reaction gas due to the formation of SeH+ (2.4%) and BrH+ (14%), but even then systematic errors in the correction of the BrH+ interference could not be avoided. Hence, the selenium recovery from human serum reference material was only 78.0 ± 0.4% when measured with hydrogen but 96.7 ± 4.0% with xenon.
Isolation and Partial Characterization of a Mycotoxin from Penicillium roqueforti (1973)

Extracts of pure cultures of Penicillium roqueforti isolated from toxic feed samples and of P. roqueforti NRRL 849 were lethal to rats by either intraperitoneal or oral administration. Purification studies guided by this test led to the isolation of a major toxin which showed intraperitoneal and oral median lethal dose values in weanling rats of 11 and 115 mg/kg, respectively. Partial characterization of the crystalline compound, C17H20O6, by infrared, ultra violet, PMR, and mass spectroscopy, and by several chemical transformations indicated the presence of three C-methyl substituents plus one acetoxy, one aldehyde, and one α,β-unsaturated ketone group. Two oxygen atoms are present either in epoxide or ether form.
Measurement of D_s^+ and D_s^{*+} production in B meson decays and from continuum e^+e^- annihilations at sqrt{s}=10.6 GeV (2001)

New precise measurements of $D_s^+$ and $D_s^{*+}$ meson production from $B$ mesons and $q\bar q$ continuum events near the $Υ(4S)$ resonance are presented in this paper. Using the BABAR data recorded in 1999 and 2000 of 20.8 fb$^{-1}$ on-resonance and 2.6 fb$^{-1}$ off-resonance, we measure the inclusive branching fractions ${\cal B}(B\to D_s^+ X) = (10.93\pm 0.19\pm 0.58\pm 2.73)%$ and ${\cal B}(B\to D_s^{*+} X) = (7.94\pm 0.82\pm 0.72\pm 1.99)%$, where the first error is statistical, the second is the systematic error, and the third is the error due to the $D_s^+\toϕπ^+$ branching fraction uncertainty. The branching fractions $Σ{\cal B}(B\to D_s^{(*)+} \bar D^{(*)}) = (5.07\pm 0.09\pm 0.34\pm 1.27)%$ and $Σ{\cal B}(B\to D_s^{*+} \bar D^{(*)}) = (4.07\pm 0.42\pm 0.53\pm 1.02)%$ have been determined from the measured $D_s^{(*)+}$ momentum spectra.
Étude algèbrique des mots de poids minimum des codes cycliques, méthodes d'algèbre linéaire sur les corps finis. (1993)

Minimum weight codewords of cyclic error-correcting codes are considered here. The elementary symmetric functions and the power-sum symmetric functions of the locators of these codewords are related by the Newton's identities. In the first chapter, they are viewed as a system of algebraic equations, whose solutions are studied by means of the Fourier transform. In chapter II, the link with cyclic error-correcting codes is established. On some examples, it is shown how to study the minimum weight codewords on the data of a Grobner basis of the ideal generated by the Newton's identities. In chapter III, the Newton's identities are considered from a theoretical point of view, and results about minimum weight codewords of a family of BCH codes are obtained. These computations occurs in the context of finite fields. In chapter IV, an algorithm is constructed for computing a normal basis of a finite field. A point of view from linear algebra is chosen, and other problems are dealt with (the computation of the minimal polynomial, of the Frobenius form of a matrix, when the factorization of the characteristic polynomial is known).

Evaluating Ergonomic Stresses in North Carolina Commercial Crab Pot and Gill Net Fishermen (2008)

There are challenges in evaluating physical demands of commercial fishing, including identifying sources of exposure variability. Low back biomechanical stresses associated with crab pot and gill net fishing were estimated; the variability was partitioned between and within fishing type, crew size, job title, and worker to improve understanding of risk factors for low back injury. The authors observed 162 person-hours of work among 25 North Carolina commercial fishermen on 16 crews. Postures and forces during fishing tasks were measured through direct and indirect observation using two methods to determine the percentage of time fishermen were exposed to high levels of low back stress. A multilevel linear model estimated exposure variability for the dependent variables by four nesting variables: fishing type, crew size, job title, and worker. Fishermen set and pulled crab pots or gill nets for 80% of the workday. Twenty-five percent of that time was spent handling gear. For both fishing types, handling heavy loads produced high peak compression values (3586 N to 5315 N) and high NIOSH lifting index values (3.3 to 5.4), but these tasks represent a small percentage of the overall work time (0 to 14%). The majority of exposure variation in non-neutral trunk posture and/or force > 9 kg, handling materials, NIOSH Lifting Index > 1, and Lumbar Motion Monitor probability of high-risk group membership > 70% was accounted for by fishing type (range 60 to 91%). Crew size was not an important source of variability for these six variables when fishing type and job title were accounted for in the model; but in the model restricted to crab pot fishing, crew size accounted for 51 to 88% of the variability in low back stress. For both models, job title comprised the majority of exposure variability for NIOSH Lifting Index > 3.0 (46 and 65%) and worker comprised the majority of variability for spine compression > 3400 N (54 and 65%). The magnitude and duration of musculoskeletal loads experienced by fishermen vary by the type of fishing and the tasks performed by the worker. Understanding this variability may help researchers target ergonomic interventions for this work population.
Multiple von Meyenburg complexes mimicking diffuse liver metastases from esophageal squamous cell carcinoma (2006)

Von Meyenburg complexes are benign liver lesions consisting of adenomatous bile duct proliferates. We present two patients suffering from esophageal cancer accompanied by the occurrence of von Meyenburg complexes. Preoperative computerized tomography (CT) of the liver had not shown these lesions. In one of the patients, diffuse nodular manifestation was found in both liver lobes, mimicking diffuse hepatic metastases. Intraoperative frozen section revealed the benign nature of the lesions in both cases. The patients underwent esophageal resection without complications. To the best of our knowledge, the coincidence of von Meyenburg complexes and esophageal cancer has never been reported before. This uncommon entity should be taken into consideration as a differential diagnosis of liver lesions in malignancies. It underlines the importance of intraoperative frozen section for liver lesions of unknown origin.
Impact of Triethanolamine as an Additive for Rechargeable Alkaline Zn/MnO<sub>2</sub>Batteries under Limited Depth of Discharge Conditions (2017)

Rechargeable alkaline Zn/MnO<sub>2</sub> batteries are being developed for use as cost-effective grid-scale energy storage devices. Previous studies have shown that limiting the depth of discharge (DOD) of the MnO<sub>2</sub> cathode extends cell lifetime while still providing a cost-effective battery system. Herein, a comprehensive study of triethanolamine (TEA) as an additive in Zn/MnO<sub>2</sub> limited DOD batteries is provided by examining the effect of TEA in full cells as well as independently on the cathode, anode, separator, and electrolyte. Improvement in cycle-ability of the cathode (on average, 80% of cycled capacity remains after 191 cycles without TEA, 568 cycles with TEA) and a decrease in ionic zinc mobility across Celgard 3501 (7.91 × 10<sup>-5</sup> cm<sup>2</sup>/min without TEA, 3.56 × 10<sup>-5</sup> cm<sup>2</sup>/min with TEA) and Cellophane 350P00 (3.26 × 10<sup>-5</sup> cm<sup>2</sup>/min without TEA, 4.74 × 10<sup>-6</sup> cm<sup>2</sup>/min with TEA) separators upon the addition of TEA are demonstrated. However, TEA increased both the reduction potential of Zn (-0.68 V vs. Hg/HgO without TEA, -0.76 V with TEA) and the solubility of Zn<sup>2+</sup> (0.813 M without TEA, 1.023 M with TEA). Overall, the addition of TEA extended the lifetime of limited DOD cells on average by 297%.
Formal Total Synthesis of (+)-Salicylihalamides A and B:  A Combined Chiral Pool and RCM Strategy (2003)

The formal total synthesis of the (+)-salicylihalamides A and B is detailed, utilizing a chiral pool approach to generate the three stereogenic centers and a ring-closing metathesis (RCM) for the formation of the macrocyclic ring structure. Starting from a known glucose-derived alcohol, the formal total synthesis was achieved in an efficient 13-step protocol in 26% overall yield. It was found that substitution at the remote phenolic group significantly influenced the ratio of the E- and Z-double bond products in the RCM step. The introduction of phenol protecting groups provided E-isomers preferentially and also enhanced the rates of the RCM reactions.
Efficacy Comparison of Escitalopram and Citalopram in the Treatment of Major Depressive Disorder: Pooled Analysis of Placebo-Controlled Trials (2002)

These data support the effectiveness of escitalopram and citalopram in the treatment of major depressive disorder, and suggest escitalopram may have a faster onset and greater overall magnitude of effect than citalopram in improving symptoms of depression and anxiety in patients with major depressive disorder.
Movement and rate of decomposition of ethoprophos in soil columns under field conditions (1977)

Abstract The rates of degradation and downward movement of ethoprophos (O‐ethyl SS‐dipropyl phosphorodithioate) were measured under field conditions in four soils in aluminium columns (40 cm long). A 10% granular formulation was incorporated in the top 10 cm at a rate of 10.0–10.5 kg a.i./ha. Under outdoor conditions during spring and summer, loss of ethoprophos approximated to first order kinetics; the half‐life was about 87 days in a humic sand and a peaty sand, with pH values of 4.5 and 4.6, respectively. In a sandy loam and a loam soil with pH values of 7.2 and 7.3, respectively, the half‐life ranged between 14 and 28 days. Under experimental conditions with fallow soils and 35.3 cm rainfall, the downward movement of substantial concentrations of ethoprophos by leaching and diffusion was restricted to a few centimetres.

Occurrence of Both Unipolar Memory and Threshold Resistance Switching in a NiO Film (2009)

We observed two types of reversible resistance switching (RS) effects in a NiO film: memory RS at low temperature and threshold RS at high temperature. We were able to control the type of RS effects by thermal cycling. These phenomena were explained using a new dynamic percolation model that can describe the rupture and formation of conducting filaments. We showed that the RS effects are governed by the thermal stability of the filaments, which arise from competition between Joule heating and thermal dissipation. This work provides us understandings on basic mechanism of the RS effects and their interrelation.
[Inhibition of NK activity by oses: effect of interleukin 2 (author's transl)]. (1982)

Several sugars can strongly inhibit the natural cytotoxicity (NK) exhibited by peripheral blood lymphocytes (PBL) against tumour cells. The inhibition of NK cytotoxicity mediated by mannose, glucose, galactose and saccharose was tested in human PBL. All these sugars significantly blocked (P less than 0.01 at 50 mM concentration) the NK cytotoxicity. The blocking is dose-dependent in a linear pattern. The sole preincubation of the attacking (NK) population is required for inhibition of cytotoxicity; no influence of the sugars were noticed on the K562 alone. In contrast, the NK cytotoxicity of PBL primed in mixed lymphocyte reaction and further cultured in presence of conditioned medium (CM), showed, aside of a clear increase (average 40% increase of specific 51Cr release, P less than 0.05) a full insensitivity to the tested sugars. Phytohaemagglutinin (PHA), interferon (IF) and an interleukin 2 (Il2) are contained in the CM. We showed that neither the PHA nor the IF preincubation of the cells can induce the insensitivity of NK for the sugars, thus our data strongly suggest that Il2 is implicated in the sugar insensitivity of the cytotoxicity of lymphocytes cultured with CM.
Comparison of supine and prone noninvasive measurements of breathing patterns in fullterm newborns (1994)

The current study was undertaken to ascertain whether shift from supine to prone posture alters the pattern of natural breathing in healthy fullterm newborns. Breathing patterns were measured in the supine and prone posture in 20 healthy fullterm infants using calibrated, noninvasive respiratory inductive plethysmography (RIP). The values for breathing pattern components in supine and prone postures expressed as means (+/- SD) were, respectively, tidal volume (VT), 14.1(+/- 3.2) and 18.9(+/- 4.9)mL; mean inspiratory flow 26.7(+/- 11.5) and 32.8(+/- 13.0)mL/s; and minute ventilation 232(+/- 75) and 288(+/- 96)mL/kg/min (P < 0.01). Less thoracoabdominal incoordination, expressed as the labored breathing index (LBI), occurred with shift from supine to prone posture in infants studied in the active behavioral stage, changing from 2.0(+/- 0.5) to 1.3(+/- 0.4) (P < 0.01). Placement of a facemask-pneumotachograph system increased VT measured with RIP by 26% in the supine, and 18% in the prone posture. Neither respiratory rate nor inspiratory time (Ti) changed with the postural shift. Therefore, change from supine to prone posture improved ventilation and increased respiratory drive as expressed by VT/Ti. Further, thoracoabdominal incoordination which took place during active sleep in the supine posture, lessened with change to the prone posture.
Cisplatin-induced tubular injury studied by water-soluble synthetic polymers. (1984)

Accumulation of a synthetic water-soluble polymer, poly-alpha, beta-[N(2-hydroxyethyl)-D,L-aspartamide-co-N(4-hydroxyphenethyl )- D,L-aspartamide] in the cells of kidney proximal tubules was used as an indicator for the functional localization of Cisplatin (CDDP) induced tubular injury in rats. Tubular accumulation of polymer was examined using 131I and fluorescence labelling for quantitative as well as morphological evaluation. It was found that reabsorption of the polymer, in which mainly the epithelium of proximal convolutions is involved, remains unaffected upon CDDP treatment in the course of one to six days after the drug administration. This finding supports on the functional level the morphological localization of CDDP injury into the straight segment of the proximal tubule.
A Characterization of Online Search Behavior (2009)

In this paper we undertake a large-scale study of online user search behavior based on search and toolbar logs. We identify three types of search: web, multimedia, and item. Together, we show that these different flavors represent almost 10 % of all online pageviews, and indirectly result in over 21 % of all pageviews. We study search queries themselves, and show that more than half of them contain direct references to some type of structured object; we characterize the types of objects that occur in these queries. We then revisit the relationship search and navigation specifically in the context of e-commerce, and consider how search aids users in online shopping tasks. 1
Detection of Two Membrane Polypeptides Induced by Abscisic Acid and Cold Acclimation: Possible Role in Freezing Tolerance (1988)

Membrane proteins labeled in vivo from cold-acclimated and ABA-treated alfalfa seedlings of two cultivars differing in cold-tolerance have been compared by SDS polyacrylamide gel electrophoresis and fluorography. Results thus obtained indicate that several qualitative changes occur in the membrane protein-profile specifically in response to cold acclimation or ABA treatment. While some polypeptides disappear from the non-acclimated protein patterns, others specifically appear in response to acclimation. Separation by two-dimensional gel electrophoresis and fluorography has confirmed the above and has enabled us to detect two proteins of Mr 42 kDa and 120 kDa that are induced by both acclimation and ABA treatment in the freezing tolerant cultivar.
Predicting Pressure Sensitivity to Luminophore Content and Paint Thickness of Pressure-Sensitive Paint Using Artificial Neural Network (2021)

An artificial neural network (ANN) was constructed and trained for predicting pressure sensitivity using an experimental dataset consisting of luminophore content and paint thickness as chemical and physical inputs. A data augmentation technique was used to increase the number of data points based on the limited experimental observations. The prediction accuracy of the trained ANN was evaluated by using a metric, mean absolute percentage error. The ANN predicted pressure sensitivity to luminophore content and to paint thickness, within confidence intervals based on experimental errors. The present approach of applying ANN and the data augmentation has the potential to predict pressure-sensitive paint (PSP) characterizations that improve the performance of PSP for global surface pressure measurements.
Optically induced catastrophic degradation in InGaAsP/InP layers (1982)

Laser-induced catastrophic degradation in InGaAsP layers has been investigated. Catastrophic dark line (CDL) defects are generated at the spontaneous radiation flux in excess of 100 MW/cm2, significantly higher than in similar GaAlAs structures. In contrast to CDL’s in GaAlAs these dark lines are shown to be due to localized melting at material defects and not at cleaved mirror facets. In view of the very high power threshold this type of catastrophic degradation should be of limited importance for the InGaAsP lasers.
