Surface Chemical Characterization Using XPS and ToF-SIMS of Latex Particles Prepared by the Emulsion Copolymerization of Methacrylic Acid and Styrene (1996)

A series of colloids based on poly(styrene) were prepared by emulsion copolymerization with various proportions of methacrylic acid. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were used to monitor changes in particle surface composition and indicated a substantial enrichment of the methacrylic acid component. Further evidence for the presence of carboxyl groups at the particle surfaces was provided by electrophoretic mobility measurements, which showed a marked increase over the pH range studied.
Observation of the photorefractive effect in a dialkylaminonitrostilbene copolymer (1993)

We report observations of the photorefractive effect in a 1:1 side-chain copolymer of N-methacryloxyethyl-N-methylaminonitrostilbene with methyl methacrylate. Without the addition of a photoconducting component, gratings were written in this polymer at 633 nm in 8-μm-thick films at low powers and were detected by use of a four-wave mixing measurement. Diffraction efficiencies of the order of 10−5 −10−4 were measured by four-wave mixing.
PLP/DM20 Expression and turnover in a transgenic mouse model of pelizaeus‐merzbacher disease (2010)

Abstract The most common cause of Pelizaeus‐Merzbacher (PMD) is due to duplication of the PLP1 gene but it is unclear how increased gene dosage affects PLP turnover and causes dysmyelination. We have studied the dynamics of PLP/DM20 in a transgenic mouse model of PMD with increased gene dosage of the proteolipid protein gene ( Plp1 ). The turnover of PLP/DM20 were investigated using an ex‐vivo brain slice system and cultured oligodendrocytes. Homozygous mice have reduced PLP translation, markedly enhanced PLP degradation, and markedly reduced incorporation of PLP into myelin. Proteasome inhibition (MG132) prevented the enhanced degradation. Numerous autophagic vesicles are present in homozygous transgenic mice that may influence protein dynamics. Surprisingly, promoting autophagy with rapamycin decreases the degradation of nascent PLP suggesting autophagic vacuoles serve as a cellular storage compartment. We suggest that there are multiple subcellular fates of PLP/DM20 when overexpressed: the vast majority being degraded by the proteasome, a proportion sequestered into autophagic vacuoles, probably fused with endolysosomes, and only a small proportion entering the myelin sheath, where its association with lipid rafts is perturbed. Transgenic oligodendrocytes have fewer membrane sheets and this phenotype is improved with siRNA‐mediated knockdown of PLP expression that promotes the formation of MBP+ myelin‐like sheets. This finding suggests that RNAi technology is in principle applicable to improve CNS myelination when compromised by PLP/DM20 overexpression. © 2010 Wiley‐Liss, Inc.
Study of Radical Decarboxylation Toward Functionalization of Naphthoquinones (2007)

Abstract In order to obtain functionalized naphthoquinones, a systematic study of the Kochi–Anderson procedure for the alkylation of quinones is presented. While linear amino acids of different lengths were good substrates for this decarboxylation procedure, chiral α‐amino acids were unsuccessful substrates. The best reaction conditions were evaluated with β‐alanine and then applied to a series of carboxylic acids to obtain chemical diversity on the naphthoquinones. We observed that the substitution of the acids is critical for the alkylation, and that it was possible to realize a double alkylation with 1,4‐naphthoquinone, even with different reactants. The Barton procedure was attempted on some substrates to compare with our results, but no reaction was observed, no matter which radical trap was used. (© Wiley‐VCH Verlag GmbH & Co.

POLY-0-AMINOPHENOL OBTAINED AT HIGH POTENTIALS BY CYCLIC VOLTAMMETRY ON SN0(2): F ELECTRODES: APPLICATION IN QUANTITATIVE DETERMINATION OF ASCORBIC ACID (2009)

In the present work the obtention of poly-o-aminophenol (POAP) at high potentials on conducting glass (SnO 2 : F) is reported. The synthesis was carried out by continuous potential cycling in a 110 -3 M o-aminophenol (OAP), 0.1 M hydrochloric acid, and 0.1 M potassium chloride solution between -0.2 and 1.5 V at 0.05 Vs -1 vs AgAgCl. The polymer growth was followed by cyclic voltammetry, UV-vis spectra, and AFM characterization. The SnO 2 : F modified electrode (SnO 2 : F/POAP) was tested in the electro-oxidation of ascorbic acid (AA) in phosphate buffer solution. This coating showed an important electrocatalytic effect because a negative anodic shift of 0.4 V with respect to a bare SnO 2 : F glass electrode was observed.
Epidemiology, Clinical Features, and Prognosis of Acute Myocardial Infarction in the Elderly (2006)

The incidence and prevalence of acute myocardial infarction (MI) increase progressively with age. In the United States, over 60% of acute MIs occur in patients 65 years of age or older, and approximately one third occur in persons over age 75. In addition, mortality rates following acute MI increase exponentially with age, such that approximately 60% of all MI deaths in the United States occur in the 6% of the population 75 years of age or older. The clinical features of acute MI vary by age. In particular, very elderly patients are less likely than younger patients to report chest pain. Conversely, confusion or altered mental status may be the presenting manifestation of acute MI in up to 20% of patients over 85 years of age. Older patients are also more likely to have "silent" or unrecognized MIs, as well as MIs without ST-segment elevation, compared with younger patients. Elderly patients with acute MI are more likely than younger patients to experience heart failure, atrial fibrillation, cardiac rupture, and shock, all of which are associated with increased mortality. Other factors contributing to the poor prognosis following acute MI in elderly individuals include a marked decline in cardiovascular reserve in the elderly, increased prevalence of comorbid conditions, underutilization of evidence-based therapies, and increased risk of iatrogenic complications.
Impact of Spirituality on Making Ethical Healthcare Decisions (2006)

Details of a speech given during a conference called 'Health Care Towards the End of Life, Ethics and Spirituality', organised by the Caroline Chisholm Centre for Health Ethics and held at St Vincent's Hospital on May 23, 2006 are presented. The topic of the conference was the impact of spirituality on making healthcare decisions. Special consideration to the relationship of patients' conscience and autonomy to their spirituality, religious beliefs or lack thereof was recommended considering some beliefs of many Christians, which could consciously or subconsciously influence their healthcare decisions.
Prevalence of Atopic Dermatitis and Pattern of Drug Therapy in Malaysian Children (2018)

The overall prevalence is comparable to that reported in the International Study of Asthma and Allergies in Childhood Phase One. There is an association between ethnicity and AD prevalence. Topical corticosteroids and emollients are the mainstay of AD management among Malaysians.
Serious gaming for sustainable manufacturing: A requirements analysis (2011)

In corporate environments, there is a growing interest in deploying serious games to support training and more specifically competence development. The goal is the acquisition of soft-skills (e.g. negotiation, leadership, and identification of weak signals) and complex competences which are needed in emerging fields such as Sustainable Global Manufacturing. Sustainability combines environmental, economic, and social dimensions and is considered to be a complex and hard to learn subject needing a lot of experience to create competence. Therefore, the construction of a serious game to support the generation of such competences is not trivial and must be founded on a sound requirements analysis. The aim of this paper is to present relevant findings from the requirements analysis phase for developing a serious game scenario for a technology-enhanced learning platform called TARGET. The target audience is composed of master grade students of business administration and young professionals employed in medium level management positions. The methodology for requirements elicitation is based on the Volere template combined with subject matter experts' interviews.
DNA content, ploidy level and number of nuclei in the human heart after myocardial infarction (1997)

Polyploidization and nuclear hyperplasia of myocytes may represent an adaptive response of the myocardium to an ischemic injury.
Integrated operation of a pressurized fixed bed gasifier and hot gas desulfurization system (1992)

The primary objective of this contract continues to be the demonstration of high fuel gas desulfurization of high temperature fuel gas desulfurization and particulate removal using a moving bed process with regenerable metal oxide sorbent. The fuel gas source for test operation is a fixed bed, air blown gasifier located at GE Corporate Research and Development in Schenectady, New York. The demonstration project also includes the design, construction, installation and test operation of a gas turbine simulator which includes a modified GE MS6000 type gas turbine combustor and a film cooled, first stage LM 6000 nozzle assembly. The hot gas cleanup (HGCU) system and the gas turbine simulator have been designed to operate with the full 8000 lb/hr fuel gas flow from the gasification of 1800 lb/hr of coal at 280 psig and 1000 to 1150 F. An advanced formulation of zinc ferrite as well as zinc titanate have been used as the regenerable metal oxide sorbents in testing to date. Demonstration of halogen removal as well as characterization of alkali and heavy metal concentrations in the fuel gas remain objectives, as well. Results are discussed.
Trip and restore distribution circuits at transmission speeds (2003)

In this paper, the authors show how to reduce tripping and restoration times for faults on distribution circuits. Using relays and/or controls with improved communications capabilities, linked together by optical fiber or other communication channels, one can detect faults and restore load to unaffected line sections faster.
Repair Processes in Radiation Biology (1984)

Three dualities underscore the role of repair in radiobiology: the discrete and random nature of energy deposition; the coupled processes of damage and repair; and the harmful and beneficial properties of radiation in connection with issues of public health and the radiation therapy of cancer, respectively. Starting with the survival curve of HeLa S3 cells, published by T. T. Puck and P. I. Marcus [J. Exp. Med. 103, 653-666 (1956)], the survival response of repair-competent mammalian cells is discussed and is related to clinical experience. This is followed by an examination of DNA repair in surviving cells from which it is inferred that even in repair-deficient cells, very likely large numbers of single- and double-strand DNA breaks are repaired because the progeny of surviving cells are essentially free of such damage. These observations support the idea that even when single-hit dose-effect relationships are involved (e.g., survival of ataxia telangiectasia cells), repair processes may play a role. Lastly, single-hit kinetics connected with the induction of neoplastic transformation are discussed. The data demonstrate that linear dose-response dependencies due to ionizing radiation (i.e., gamma rays and fission-spectrum neutrons) can be modulated by dose protraction, but that neither the direction nor the extent of such modulations can be predicted on theoretical grounds. To be applied more effectively for the benefit of mankind, therefore, it remains necessary to understand fully the biological mechanisms of the action of ionizing radiation.
Inhibition of Urokinase by Complex Formation with Human Antithrombin III in Absence and Presence of Heparin (1978)

Summary Human antithrombin III was purified from fresh human plasma by affinity chromatography on heparin-Sepharose®, affinity chromatography on concanavalin A Sepharose®, gel filtration on Ultrogel® AcA 34, ion exchange chromatography on DEAE A-50 Sephadex® and preparative agarose gel electrophoresis. The hydrolytic activity of urokinase (plasminogen activator from urine) on acetyl-glycyl-L-lysine methyl ester acetate (Ac-gly-lys-OMe Ac) was inhibited by antithrombin III in a slow time-dependent manner. Heparin accelerated the reaction between activator and inhibitor. Inhibition of catalytic activity was associated with the formation of an 1:1 molar complex between activator and inhibitor as revealed by sodium dodecyl sulphate polyacrylamide gel electrophoresis. The complex was also demonstrated by crossed Immunoelectrophoresis against anti-antithrombin III.
Mechanical Properties and Fabrication of WC-Co Hard Materials by Rapid Sintering Method for Friction Stir Welding Tool Application (2012)

Using the pulsed current activated sintering method, the WC-10wt.% Co materials were densified using a WC and Co powder. The WC-Co almost completely dense with a relative density of up to 99.5 % after the simultaneous application of a pressure of 60 MPa and an electric current for 3 minutes almost without any significant change in the grain size. The average grain size of about <TEX>$0.3{\mu}m$</TEX>. The hardness and fracture toughness at <TEX>$1000^{\circ}C$</TEX> were about <TEX>$2200kg/mm^2$</TEX> and <TEX>$9.8MPa.m^{1/2}$</TEX>, respectively.
Bond Pad Design With Low Capacitance in CMOS Technology for RF Applications (2007)

A new bond pad structure in CMOS technology with low capacitance for gigahertz radio frequency applications is proposed. Three kinds of inductors stacked under the pad are used in the proposed bond pad structure. Experimental results have verified that the bond pad capacitance is reduced due to the cancellation effect provided by the inductor embedded in the proposed bond pad structure. The new proposed bond pad structure is fully process-compatible to general CMOS processes without any extra process modification
Debate on the Status of Western Education and Working for the Nigerian Government Between Mallam Isa Ali Ibrahim Pantami and Mallam Muhammad Yusuf Maiduguri (2018)

25 JUNE 2006 [Trans.: Abdulbasit Kassim] <italic>During the period 2004–2008, there were several debates between Muhammad Yusuf and other Salafi scholars, but this is the first whose video is extant. His opponent, Isa Pantami is western-educated and much better prepared than Yusuf, either because the latter was not told of the subjects to be debated (part 7) or because his thoughts were not well-developed. The debate lasted for six hours, of which approximately three hours have survived on video. The full text of the extant videos is approximately forty-six pages long in ten parts...</italic>
Clínica y terapéutica de la anquilostomiasis y de la tricocefalosis infantil (1955)

1. A study is presented of the frequency of infestation by Ancylostoma doudenale or by Necator americanus and by Trichuris trichittra in 2026 chil­dren leaving the Pediatrics Section of Hospital San Juan de Dios, San Jose, C. R. during the first four months of 1953. 2. Of these children, 32.7 per cent were positive for one or both parasites, mixed infestation being quite frequent. 3. The distribution of the parasites is analysed according to age and sex, including the degree of anemia when present. 4. A study is made of 63 children under treatment at the Pediatrics Section of Hospital San Juan de Dios during 1954 and showing heavy uncinariasis and trichocephaliasis; the salient facts are analysed regarding clinic­al, hematological, and parasitological manifestation. Flocculation tests and blood protein values are also considered. 5. The various therapeutic procedures, including bload transfusions, ferrotherapy and the usual anti-helminthics, are discussed and evaluated.
Oxidative Metabolism in <i>Pediococcus pentosaceus</i> III. Glucose Dehydrogenase System (1965)

Lee, Chin K. (North Carolina State of the University of North Carolina, Raleigh), and Walter J. Dobrogosz. Oxidative metabolism in Pediococcus pentosaceus. III. Glucose dehydrogenase system. J. Bacteriol. 90:653-660. 1965.-A method was developed for the purification of glucose dehydrogenase from Pediococcus pentosaceus Az-25-5. The procedures included treatments with protamine sulfate, ammonium sulfate, and heat in addition to acid precipitation, calcium phosphate adsorption and elution, and diethylaminoethyl-Sephadex column chromatography. The final preparation thus obtained was purified 255-fold and exhibited both similarities and dissimilarities to the same enzyme isolated from other sources. The enzyme is absolutely specific for nicotinamide adenine dinucleotide phosphate (NADP) as a cofactor, and oxidizes only glucose or its analogue 2-deoxyglucose via the following reversible reaction: beta-d-glucose + NADP right harpoon over left harpoon d-glucono-delta-lactone + NADPH(2) + H(+). K(m) values were 2.3 x 10(-2) for glucose and 2 x 10(-4) for NADP. Monovalent cations were required for stability of the enzyme and stimulated activity. The pH optimum was 7.0, and the equilibrium constant was determined to be 13.4 x 10(-7) at pH 6.4. Among the Lactobacillaceae, glucose dehydrogenase activity was found to be essentially limited to members of the genus Pediococcus. Studies on the enzymatic composition of P. pentosaceus viewed in conjunction with other available data led to the conclusion that this enzyme is not involved to any significant extent in the energy metabolism of this organism.
Update on the Pharmacologic Treatment of Hypertension in Pediatrics (2012)

J Clin Hypertens (Greenwich). 2012; 14:383-387. ©2012 Wiley Periodicals, Inc. The past decade of investigation into the pharmacologic treatment of hypertension in children has been rewarding. The studies have shown that blood pressure medications effectively reduce blood pressure in children with hypertension and that these agents are generally well tolerated with few treatment-related adverse effects. While we have advanced our capacity to make rational therapeutic decisions, future efforts must be directed towards comparing the effectiveness of the different classes of antihypertensive agents and studies evaluating the impact of antihypertensive agents on outcome.
Non-crypto Hardware Hash Functions for High Performance Networking ASICs (2011)

Hash functions are vital in networking. Hash-based algorithms are increasingly deployed in mission-critical, high speed network devices. These devices will need small, quick, hardware hash functions to keep up with Internet growth. There are many hardware hash functions used in this situation, foremost among them CRC-32. We develop parametrized methods for evaluating hash function output quality so as to better compare similar hash functions. We use these methods to explore the quality of candidate hash functions, including CRC-32, H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (with fixed seed), MD5 and others. We also propose optimized building blocks for hardware hash functions based on SP-networks. Given a size budget of 4K gates and only 1 cycle to compute the result, we demonstrate a 128 bit input, 64 bit output hash function built using this framework that ranks highly in our tests.
Dense estimation and object-based segmentation of the optical flow with robust techniques (1998)

In this paper, we address the issue of recovering and segmenting the apparent velocity field in sequences of images. As for motion estimation, we minimize an objective function involving two robust terms. The first one cautiously captures the optical flow constraint, while the second (a priori) term incorporates a discontinuity-preserving smoothness constraint. To cope with the nonconvex minimization problem thus defined, we design an efficient deterministic multigrid procedure. It converges fast toward estimates of good quality, while revealing the large discontinuity structures of flow fields. We then propose an extension of the model by attaching to it a flexible object-based segmentation device based on deformable closed curves (different families of curve equipped with different kinds of prior can be easily supported). Experimental results on synthetic and natural sequences are presented, including an analysis of sensitivity to parameter tuning.
Wideband microstrip series‐fed magnetic dipole array antenna (2014)

A wideband microstrip series‐fed magnetic dipole array antenna is proposed. The five‐element dipole array antenna is designed to achieve both wide bandwidth and high gain because of its microstrip series feeding structure. The low‐profile low‐cost array is suitable for applications such as wideband high‐gain wireless communications. Measured and simulated results are in good agreement. The measured impedance bandwidth of the array is enhanced up to 28.6% (5.0–6.7 GHz). The radiation patterns show its advantages of high gain (about 10 dBi), endfire radiation and vertical polarisation.
The way we were: command and control centres in the global space-economy on the eve of the 2008 geoeconomic transition (2008)

This is a short note to take stock of where we were before the financial crisis\nbegan to seriously undermine the global economy in late 2008. For once the\nphrase ‘to turn the world upside down’ could hardly be more merited: the most\nright-wing US President in living memory is accused by members of Congress\nin his own party of being a ‘Bolshevik’ pursuing ‘financial socialism’ while in\nthe UK the ‘New Labour’ government is being praised for nationalising more\nof the British economy than the most socialist, post-1945 Labour government\never did. Instead of the diminution of the state, the era of neoliberal\nglobalization appears to have culminated in a reassertion of state economic\npower: place-based public finance has come to the rescue of flow-based\nprivate finance.
Formal Development of Safe and Secure Java Card Applets (2005)

Abstract This thesis is concerned with different aspects of JAVA CARD application de-velopment and use of formal methods in the J AVA CARD world. JAVA CARD is atechnology that provides means to program smart (chip) cards with (a subset of) the JAVA language. The use of formal methods in the JAVA CARD contextis highly justified due to the criticality of J AVA CARD applications. First of all,J AVA CARD applications are usually security critical (e.g., authentication, elec-tronic cash), second, they are cost critical (i.e. they are distributed in large amounts making updates quite difficult) and finally, they can also be legallycritical (e.g., when the digital signature law is considered). Thus the robustness and correctness of JAVA CARD applications should be enforced by the best meanspossible, i.e. by the use of formal verification techniques. At the same time J AVAC ARD seems to be a good target for formal verification--due to the relative sim-plicity of J AVA CARD applications (as compared to full JAVA), formal verificationbecomes a feasible and manageable task. In this thesis, we touch upon different levels of JAVA CARD application development and the use of formal methods.We start by defining a UML/OCL supported development process specifically tailored to JAVA CARD applications, then we go on to define an extension to thelogic used in formal verification of J AVA CARD programs to handle so called &amp;quot;ripout &amp;quot; properties (properties that should be maintained in case of an unexpected termination of a JAVA CARD program), which are specific to JAVA CARD. Finally,we end up with a simple tool support for J AVA CARD program compilation andtesting inside a CASE tool. The thesis contains three papers focusing on these aspects. The main purpose of this work is to ensure the robustness of JAVAC
