Silica stabilized iron particles toward anti-corrosion magnetic polyurethane nanocomposites (2011)

A sol–gel method is used to introduce fluorescent silica shells with tunable thickness on the spherical carbonyl iron particles (CIP) by a combined hydrolysis and condensation of tetraethyl orthosilicate (TEOS). Both gelatin B and 3-aminopropyltriethoxysilane (APTES) are used as primers to render the metal particle surface compatible with TEOS. The silica shell is formed through the hydrolysis and condensation of TEOS on the primer-treated CIP and the shell thickness can be controlled by varying the ratio of chemicals, such as TEOS and ammonia. The silica shell on the particle surface is confirmed by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA) and transmission electron microscopy (TEM). The magnetic and anti-corrosive properties of the CIP and CIP-silica particles have been evaluated. A conformal coating shell is confirmed surrounding the CIP against their etching/dissolution by protons. Polyurethane composites filled with CIP and CIP-silica particles are fabricated with a surface initiated polymerization (SIP) method. A salt fog industrial-level test indicates an improved anti-corrosive behavior of the CIP-silica/PU composites than that of the CIP/PU composites. Both CIP-silica particles and CIP-silica/PU composites exhibit better thermal stability and antioxidation capability than their CIP and CIP/PU counterparts, respectively due to the stronger barrier effect of the noble silica shell. The insulating silica shell decreases the efficiency of the electron transportation among the particles and thus leads to a higher resistivity in the composites.
Object view in spatial system dynamics: a grassland farming example (2016)

Spatial system dynamics (SSD) models are typically implemented by linking stock variables to raster grids while the use of object representations of human artefacts such as buildings or ownership has been limited. This limitation is addressed by this article, which demonstrates the use of object representations in SSD. The objects are parcels of land that are attributed to grassland farms. The model simulates structural change in agriculture, i.e., change in the size of farms. The aim of the model is to reveal relations between structural change, farmland fragmentation and variable farmland quality. Results show that fragmented farms tend to become consolidated by structural change, whereas consolidated initial conditions result in a significant increase of fragmentation. Consolidation is reinforced by a dynamic land market and high transportation costs. The example demonstrates the capabilities of the object-based approach for integrating object geometries (parcel shapes) and relations between objects (distances between parcels) dynamically in SSD.

Nanophotonics for information systems integration (2005)

The paper investigates and experimentally demonstrates components and devices based on engineered birefringent materials (space variant and space invariant), photonic crystals and surface plasmon polariton based components. The integration of these components with quantum dots to enhance nonlinear response functionality is also being investigated.
Predicting the Fate of Acute Ischemic Lesions Using Perfusion Computed Tomography (2008)

Both rCBF and rMTT can be used to predict the ultimate pathological prognosis of cerebral ischemia. Perfusion computed tomography is a very useful early-stage tool for the assessment of these patients.
Effect of Cryopreservation on Autologous Chimeric Antigen Receptor T Cell Characteristics (2019)

As clinical applications for chimeric antigen receptor T cell (CART) therapy extend beyond early phase trials, commercial manufacture incorporating cryopreservation steps becomes a logistical necessity. The effect of cryopreservation on CART characteristics is unclear. We retrospectively evaluated the effect of cryopreservation on product release criteria and in vivo characteristics in 158 autologous CART products from 6 single-center clinical trials. Further, from 3 healthy donor manufacturing runs, we prospectively identified differentially expressed cell surface markers and gene signatures among fresh versus cryopreserved CARTs. Within 2 days of culture initiation, cell viability of the starting fraction (peripheral blood mononuclear cells [PBMNCs]) decreased significantly in the cryo-thawed arm compared to the fresh arm. Despite this, PBMNC cryopreservation did not affect final CART fold expansion, transduction efficiency, CD3%, or CD4:CD8 ratios. In vivo CART persistence and clinical responses did not differ among fresh and cryopreserved final products. In healthy donors, compared to fresh CARTs, early apoptotic cell-surface markers were significantly elevated in cryo-thawed CARTs. Cryo-thawed CARTs also demonstrated significantly elevated expression of mitochondrial dysfunction, apoptosis signaling, and cell cycle damage pathways. Cryopreservation during CART manufacture is a viable strategy, based on standard product release parameters. The clinical impact of cryopreservation-related subtle micro-cellular damage needs further study.
Tat-Associated Kinase, TAK, Activity Is Regulated by Distinct Mechanisms in Peripheral Blood Lymphocytes and Promonocytic Cell Lines (1998)

TAK, a multisubunit cellular protein kinase that specifically associates with the human immunodeficiency virus Tat proteins and hyperphosphorylates the carboxyl-terminal domain of RNA polymerase II, is a cofactor for Tat and mediates its transactivation function. The catalytic subunit of TAK has been identified as cyclin-dependent kinase Cdk9, and its regulatory partner has been identified as cyclin T1; these proteins are also components of positive transcription elongation factor P-TEFb. TAK activity is up-regulated upon activation of peripheral blood lymphocytes and following macrophage differentiation of promonocytic cell lines. We have found that activation of peripheral blood lymphocytes results in increased mRNA and protein levels of both Cdk9 and cyclin T1. Cdk9 and cyclin T1 induction occurred in purified CD4(+) primary T cells activated by a variety of stimuli. In contrast, phorbol ester-induced differentiation of promonocytic cell lines into macrophage-like cells produced a large induction of cyclin T1 protein expression from nearly undetectable levels, while Cdk9 protein levels remained at a constant high level. Measurements of cyclin T1 mRNA levels in a promonocytic cell line suggested that regulation of cyclin T1 occurs at a posttranscriptional level. These results suggest that cyclin T1 and TAK function may be required in differentiated monocytes and further show that TAK activity can be regulated by distinct mechanisms in different cell types.
Thiele-Winter acetoxylation of quinones. Part IV. Quinones containing one or more t-butyl groups (1972)

The acetoxylation of many 1,4- and 1,2-benzoquinones and two diphenoquinones containing one or more t-butyl groups has been studied; also most of the relevant earlier work has been repeated. The results show that acetoxylation rarely occurs ortho to a t-butyl group. In eight of the quinones studied the reaction resulted in replacement of a t-butyl by an acetoxy-group. A mechanism for this acetoxyde-t-butylation is proposed. One of the ortho-benzoquinones (5-methyl-3-t-butyl) reacted partly as such and partly in its tautomeric quinone methide form to give 1,2,4-triacetoxy-5-methyl-3-t-butylbenzene (20%) and 1,2-diacetoxy-5-acetoxymethyl-3-t-butylbenzene (14.5%).
Effect of different treatment technologies on stabilization of rice bran (2012)

Stabilization was the prerequisite for comprehensive utilization of rice bran.In order to compare the effect of different treatment technologies on stabilization of rice bran,3 kinds of technologies including short-term microwave,high-temperature baking and extrusion were applied with lipase activity and acid value as indicators for optimization of stabilized process.The results showed that lipase inhibition rates were 85%in microwave power of 720 W for 90 s,72%in baking temperature of 130℃for 30 min,76%with rice bran moisture content of 19%,barrel temperature of 130℃and screw speed of 180 r/min in extrusion.The acid value of rice bran treated by short-term microwave,high-temperature baking,extrusion were 9.20,10.12,11.06 mgNaOH/g respectively with the blank control of 22.96 mgNaOH/g after 10 days storage in 37℃.Conclusions demonstrated that the effect of the short -term microwave treatment on stabilization of rice bran was the best.

METHANOL REFORMING REACTION OVER COPPER-CONTAINING MIXED OXIDES (1976)

Abstract Methanol was decomposed into hydrogen and carbon dioxide in the presence of water at atmospheric pressure over copper-containing mixed oxides, indicating that the reforming reaction CH3OH + H2O = CO2+ 3H2 proceeded to an appreciable extent. The mixed oxides were active and selective for the reforming reaction whereas the single oxides which constituted the mixed oxides were much less active for the reaction.
200 MHz 0.8 μm CMOS gradient vector processor for real-time execution (2002)

This paper describes a gradient vector processor which forms an important part of a shading processor being developed for a high resolution high performance real-time general purpose volume imaging system. The proposed architecture overcomes current image resolution and frame-rate limitations through the use of custom high-speed processors. The gradient vector processor evaluates three arithmetic operations: a square and add operation, square-root, and three division operations. Fully pipelined operation produces a vector every 5 ns or with a 200 MHz frequency at V/sub dd/=3 V and with an accuracy of /spl plusmn/0.78%. The algorithms and implementation in silicon are described in detail.
Pathogenicity Grouping of Isolates of<i>Leptosphaeria maculans</i>on<i>Brassica napus</i>Cultivars and Their Disease Reaction Profiles on Rapid-Cycling Brassicas (1991)

The pathogenic variability among isolates of Leptosphaeria maculans from different geographic regions was tested using 39 isolates from North America, Europe, and Australia against Brassica napus cultivars Westar, Quinta, and Glacier. An additional 62 single-ascospore isolates from oilseed rape debris from Saskatchewan and Manitoba, Canada, and from Western Australia and New South Wales, Australia, were also tested to study pathogen variability within locations
Influence of Chemical Pressure on the Superconductivity of La<sub>1.8</sub>Sr<sub>0.2</sub>CuO<sub>4</sub> (1987)

The influence of Ca in place of Sr and Eu in place of La on the superconducting and normal state behaviour of La 1.8 Sr 0.2 CuO 4 has been investigated. Both the substituents tend to depress the superconducting transition temperature, whereas the degree of semiconducting (localization)-like behaviour in resistance for the air-annealed specimens in the normal state are widely different. The data are discussed in terms of possible size and charge mismatch effects.
Transformation of arachidonic acid into an iodolactone by the rat thyroid. (1980)

In the presence of iodide and hydrogen peroxide, lactoperoxidase, an enzyme model for thyroid peroxidase, catalyzed the conversion of arachidonic acid into several iodinated products. The major product was identified as 6-iodo-5-hydroxy-eicosatrienoic acid, delta-lactone (iodolactone), on the basis of 125I incorporation, mass spectrometry, proton magnetic resonance spectroscopy, and chemical modifications. Using this compound as a standard, two methods were developed to establish and quantitate the production of iodolactone by the rat thyroid in vitro: 125I labeling followed by reversed phase high pressure liquid chromatography and combined gas chromatography-mass spectrometry. Addition of iodide and arachidonic acid to rat thyroid lobes resulted in the formation and release of the iodolactone, which was inhibited by methimazole. These data suggest that peroxidases capable of oxidizing halides could provide a new pathway of arachidonic acid metabolism, besides cyclooxygenase and lipoxygenases.
Derivatives of blood coagulation factor IX contain a high affinity Ca2+-binding site that lacks gamma-carboxyglutamic acid. (1984)

We have examined the calcium-binding properties and metal ion-dependent conformational changes of proteolytically modified derivatives of factor IX that lack gamma-carboxyglutamic acid (Gla) residues. Equilibrium dialysis experiments demonstrated that a Gla-domainless factor IX species retained a single high affinity calcium ion-binding site (Kd = 85 +/- 5 microM). Ca2+ binding to this site was accompanied by a decrease in intrinsic fluorescence emission intensity (Kd = 63 +/- 15 microM). These spectral changes were reversed upon the addition of EDTA. Titration with Sr2+ resulted in little change in fluorescence intensity below 1 mM, while titration with Tb3+ caused fluorescence changes similar to those observed with Ca2+. Tb3+ and Ca2+ appear to bind to the same site because tryptophan-dependent terbium emission was reduced by the addition of Ca2+. Similar results were obtained with a Gla-domainless factor IX species lacking the activation peptide. Gla domain-containing factor IX species exhibited fluorescence changes similar to those of the Gla-domainless proteins at low Ca2+, but an additional structural transition was found at higher Ca2+ concentrations (apparent Kd greater than 0.8 mM). Thus, the conformations of factor IX proteins are nucleated and/or stabilized by calcium binding to a high affinity site which does not contain Gla residues. The binding of Ca2+ to lower affinity Gla domain-dependent metal ion-binding sites elicits an additional conformational change. The strong similarities between these results and those obtained with protein C (Johnson, A. E., Esmon, N. L., Laue, T. M. & Esmon, C. T. (1983) J. Biol. Chem. 258, 5554-5560), coupled with the remarkable sequence homologies of the vitamin K-dependent proteins, suggest that the high affinity Gla-independent Ca2+-binding site may be a common feature of vitamin K-dependent proteins.
Standardized method for solubility and storage of capsaicin-based solutions for cough induction (2014)

We recommend the use of a 10% ethanol/water solvent system without Tween in the preparation of capsaicin solutions for tussigenic challenges. While this solvent system does not provide complete solubility, we have detailed a method for capsaicin solution preparation that will account for this loss of solubility, while maintaining a solution that is Tween-free and safe for human inhalation.
Two-year clinical experience with a computed radiography system (1988)

Computed radiography (CR) is a radiographic imaging technology, announced in 1 981 [1], that generates a conventional radiographic image in digital form. The system has been gradually introduced into various clinical environments during the past 3 years [2, 3]. Currently, more than 80 systems are in operation, most of them in Japan. A CR system consists of two major components: (1) a reusable laser-stimulated luminescent phosphor imaging plate and (2) a scanning and recording mechanism. The imaging plate is housed inside a cassette similar to the one used in a film/screen system. Exposure to radiation causes a latent image to form on the plate. The plate is processed through a laser scanning mechanism for extracting the radiographic image, a process that is analogous to the development of a film. The extracted image can either be recorded on a lasersensitive film as an 8 x 10 in. (20.3 x 25.4 cm) or a 7 x 8.5 in. (1 7.5 x 21 .5 cm) hard copy or stored as a digital image. The latter can be archived to a digital storage device and displayed on a video monitor. Because the imaging plate has a much larger dynamic range than a film/screen receptor, CR has the potential of minimizing technical errors caused by overor underexposure as wall as lowering the radiation dose delivered to the patient. We installed the system (1) to investigate various clinical applications of this new technology, (2) to attempt to lower the radiation dose to the patient without sacrificing image quality, and (3) to use it as an image-acquisition device for our picture archiving and communication systems (PACS) [4, 5]. This report describes our experience with the system during its first 2 years in clinical practice. The Computed Radiography System and Its Accessories
Fast 3‐D imaging from a deviated borehole using tensor induction logging data with LWD applications (2004)

There is growing interest in the development of new borehole electromagnetic induction methods capable of characterizing the conductivity distribution in the space surrounding a borehole. We examine the application of this tool for imaging in deviated boreholes. This technique may be extremely important in logging while drilling (LWD) and other petrophysical applications. We use localized quasi‐linear (LQL) approximation as a numerical tool for solving the inverse problem.
Transcranial magnetic stimulation for depression and other psychiatric disorders (2001)

rTMS has demonstrable beneficial effects in depression. The extent and the duration of the anti-depressant effect of rTMS has yet to be defined. There now needs to be randomized controlled trials to compare rTMS directly with standardized electroconvulsive therapy in order to take this subject forward. With regard to the treatment of other mood disorders and schizophrenia, we are at an early stage in the assessment of further studies that are needed to examine any potential role for rTMS.
New speech enhancement techniques using the pitch mode modulation model (2002)

Speech enhancement is often required prior to speech recognition and speaker identification (SI) systems. The new speech enhancement techniques described herein are based on the Pitch Mode Modulation Model (PMMM). The PMMM exploits the time-synchrony present in speech to time-warp the speech waveform such that the quasi-periodic signal becomes periodic. After this nonlinear preprocessing step, the speech signal is enhanced by comb filtering and rewarping. The enhancement technique is used with a standard cepstrum-based SI system and is shown to significantly reduce the sensitivity of the system to mismatches between training and testing data. Other applications of the enhancement model are also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Estimating Pore Pressure Using Compressional and Shear Wave Data from Multicomponent Seismic Nodes in Atlantis Field, Deepwater Gulf of Mexico (2010)

Pore pressures for the shallow sub‐seafloor sediments at the Atlantis field are estimated by analysis of P and S wave velocities observed seismic data recorded by a patch of ocean‐bottom multicomponent nodes. A modified Eaton's algorithm for pressure prediction is applied, and estimated overpressure locations are compared to known hazardous shallow water flow zones evaluated from a batch‐set drilling project.
Doping of ZnTe by molecular beam epitaxy (1994)

We have grown Cl-doped ZnTe under different growth conditions and N-doped ZnTe on different orientations. n-type doping was achieved for the first time by proper control of the Zn/Te beam flux. A p-type doping level of 1×1020 cm−3, which is the highest reported, was obtained by substrate tilting. These phenomena can be analyzed by the surface bonding structure analogous to the impurity concentration in the III-V compound semiconductors.
O coletivo, o social e o socioambiental nas representações através do discurso do sujeito coletivo (2012)

O artigo discute a Teoria das Representações Sociais (TRS) em uma perspectiva socioambiental. Para tanto, apresentamos o conceito das Representações, em sua evolução histórica desde Durkheim, Moscovici, entre outros autores, em suas interpretações e estudos. A seguir, abordamos a aplicabilidade das TRS ao Discurso do Sujeito Coletivo (DSC) no âmbito da Pesquisa Qualitativa, como técnica que busca revelar o pensamento de um grupo e seus componentes, sobre assuntos que estão imersos na coletividade. Finalmente, apresentamos a proposta de abordagem socioambiental das Representações, pela interpretação do caráter dinâmico da relação entre natureza, indivíduo e seu grupo de trabalho em suas atividades laborais a partir de uma investigação em andamento na Universidade Federal de Pelotas – UFPel.
Clinical evaluation of a fully automated chromogenic method for prothrombin time compared with a conventional coagulation method. (1984)

The clinical usefulness of a chromogenic method for prothrombin time (PT) determination has been assessed in a wide range of clinical conditions, and it is compared with the conventional clotting method for PT. The new method appears to be as sensitive as the clotting PT to deficiencies of clotting factors of the extrinsic and common pathway, except for fibrinogen. Patients with proven liver disease were correctly diagnosed with a prevalence of abnormal results comparable to that by the clotting PT. Results by the two methods correlated highly (r = 0.96) for normal and congenitally deficient plasmas as well as for plasmas from patients on oral anticoagulant treatment (r = 0.95). High reproducibility (between-assay CV less than 3%) and easy adaptation to centrifugal analyzers make it a suitable candidate to replace the conventional method.
