Interference of Dimethazone with Formation of Terpenoid Compounds (1986)

Abstract Dimethazone is a bleaching herbicide without any peroxidative activity. In addition to the inhibition of chlorophylls, carotenes, and xanthophylls, decreased formation of other prenyl lipids (phytol and α-tocopherol) can be observed in the presence of dimethazone. Application of this herbicide to pea plants results in the inhibition of longitudinal growth of the newly formed internodes which can be reversed by gibberellic acid. Apparently, dimethazone also decreases the endogenous gibberellin levels. As the formation of all the compounds assayed is inhibited to the same extent and as I 50 -values for chlorophyll and carotenoid biosynthesis are identical (about 10 µᴍ dimethazone), the various effects of dimethazone are explained by a single enzyme target in the terpenoid biosynthetic pathway between acetate and geranylgeranyl pyrophosphate.
Liquid crystalline light-emitting thermally stable readily processable substituted polyacetylenes (2001)

The backbone absorption in 2 and 3 are weak but upon photoexcitation, the polymers emit strong violet light of 369 nm, whose intensities are higher than that from poly(l-phenyl-l-octyne), a well-known highly-fluorescent polyacetylene. The main chain of 3 absorbs strongly at 380 nm, and the polymer is completely nonluminescent. All the polymers are thermally stable and form enantiotropic monolayer SmA phase, with 1 adopting well-ordered packing arrangements.

Comparative study of glass and plastic refractive microlenses and their fabrication techniques (2004)

In this paper we review the most important fabrication techniques for glass and plastic refractive microlenses and we quantitatively characterize in a systematic way the corresponding state-of-the-art microlenses which we obtained from selected research groups. For all our measurements we rely on three optical instruments: a non-contact optical profiler, a transmission Mach-Zehnder interferometer and a Twyman-Green interferometer. To conclude we survey and discuss the different fabrication techniques by comparing the geometrical and optical characteristics of the microlenses.

Overcoming the Challenges of Drug Discovery for Neglected Tropical Diseases: The A·WOL Experience (2013)

Neglected tropical diseases (NTDs) are a group of 17 diseases that typically affect poor people in tropical countries. Each has been neglected for decades in terms of funding, research, and policy, but the recent grouping of them into one unit, which can be targeted using integrated control measures, together with increased advocacy has helped to place them on the global health agenda. The World Health Organization has set ambitious goals to control or eliminate 10 NTDs by 2020 and launched a roadmap in January 2012 to guide this global plan. The result of the launch meeting, which brought together representatives from the pharmaceutical industry, donors, and politicians, was the London Declaration: a series of commitments to provide more drugs, research, and funds to achieve the 2020 goals. Drug discovery and development for these diseases are extremely challenging, and this article highlights these challenges in the context of the London Declaration, before focusing on an example of a drug discovery and development program for the NTDs onchocerciasis and lymphatic filariasis (the anti-Wolbachia consortium, A·WOL).
Determination of Folic Acid Metabolites in Normal Subjects and in Patients with Nutritional Megaloblastic Anemia. (1962)

Three microbiological assays were employed simultaneously (L. casei, S. fecalis, and P. cerevisiae) for determination of folic acid (F.A.) metabolites in whole blood and serum. Normal values were established with all these bioassays in healthy subjects. In a group of patients with severe megaloblastic anemia concentrations of all the F.A. metabolites in the whole blood were found to be remarkably reduced. The most striking decrease was found with the L. casei and P. cerevisiae assays. The results indicate an almost complete depletion of F.A. content of the red cells.

Optical-Thermo-Transition Model of Reduction in On-Resistance of Small GaN p–n Diodes (2013)

The forward current ( I F ) of GaN p–n diodes forward biased at 5 V was found to be proportional to anode perimeter and independent of temperature (273–373 K). Although this I F characteristic contributes to reduction in specific on-resistance ( R on A ) of small GaN p–n diodes, the mechanism involved is yet to be understood. Accordingly, in this study, an optical-thermo-transition model for the reduced R on A in small GaN p–n diodes is proposed. The energy of photons that are created through radiative recombination around the edge of anode electrode is considered to be used for optical-thermo-transition; that is, electrons are emitted from ionized acceptors to conduction bands, and the resultant neutralized acceptors are ionized through electron capture from valence bands. Since known self-heating and intrinsic-photon-recycling effects are considered to be negligible, optical-thermo transition and enhanced radiative recombination (due to large perimeter-to-area ratio) are concluded to play a dominant role in reducing R on A .
Triplet states at an O vacancy in α-quartz (2002)

The energy landscape of an \ensuremath{\alpha}-quartz O vacancy in the lowest triplet state is investigated. Four local minima are identified and geometries, total energies, and electron paramagnetic resonance (EPR) parameters are obtained. On the basis of calculated values for the magnetic dipole interaction between the electrons two of the structures are identified with known triplet centers detected by EPR. The effect of Ge substitution is studied, and it is concluded that Ge impurities in silica act as traps for dangling bonds with a trapping energy of $\ensuremath{\sim}1.5 \mathrm{eV}$ relative to Si ions.
Observer-Based Stabilization of Systems With Quantized Inputs and Outputs (2018)

We study a stabilization problem for systems with quantized signals. We propose encoding strategies for three signals: the plant output, the control input, and the estimate of the plant output. A controller generates the estimate of the plant output in addition to the control input and then transmits their quantized data to a plant for control and quantization. We obtain sufficient conditions for local practical stability under bounded disturbances and noise. We first develop an encoding method for general stabilizing gains and then tailor it to deadbeat gains. Finally, we illustrate the proposed encoding methods with numerical simulations.

Elevated Temperature Tensile and Creep Rupture Properties of INCONEL alloy 725 (1997)

INCONELB alloy 725 (UNS N07725) is a highly corrosion resistant nickel based alloy capable of being age-hardened to high strength levels. In order to determine the potential applicability of alloy 725 in aircraft gas turbine engines, a research program was undertaken to study the solution anneal and age-hardening treatments for required elevated temperature properties. This paper presents the microstructure, tensile and creep rupture properties for several heat treatments.
Calculation of Stresses and Slip in Structural Layers of Unbonded Flexible Pipes (1987)

This paper deals with the behavior of high-pressure unbonded flexible steel pipes which can be used as risers in offshore applications. It concerns primarily the behavior of the internal structure of the pipe. A theoretical approach allows to establish simple formulas for evaluating: the stresses, and the contact pressures between layers due to axisymmetrical loads; the stresses due to bending; the relative slip between layers due to bending. This is a first step towards the evaluation of the life expectancy of flexible pipes. It must be completed by the determination of friction and wear factors through test results.
Predictive Toxicology of cobalt ferrite nanoparticles: comparative in-vitro study of different cellular models using methods of knowledge discovery from data (2013)

The observed correlation between the oxidative stress, caused by the presence of the Co-Fe NPs, with the hierarchy of sensitivity of the different cell types towards toxicity, suggests that oxidative stress is one possible mechanism for the toxicity of Co-Fe NPs.
Fluorescence from rubrene single crystals: Interplay of singlet fission and energy trapping (2013)

We have studied fluorescence in rubrene single crystals by use of fluorescence up-conversion, fluorescence anisotropy, and temperature-dependent time-resolved fluorescence techniques. Thermally activated singlet fission was demonstrated to play an important role in the quenching of two intrinsic fluorescence bands, 565 and 610 nm. At low temperatures, singlet fission is suppressed while another process, namely energy trapping, becomes pronounced. The 650 nm fluorescence originates from the hole trap states located 0.27 eV above the valence band.

Midcarpal and STT Arthritis in Patients with CMC Arthritis (2015)

Purpose: Carpometacarpal (CMC) arthroplasty provides well-documented pain relief with preservation of thenar function for the treatment of basal joint arthritis. Nevertheless, a segment of the population undergoing this procedure will continue to have pain following surgery. Anecdotally, the senior authors hypothesize that unrecognized midcarpal arthritis is a major contributor to persistent pain after CMC arthroplasty. The prevalence of midcarpal arthritis in patients with basal joint arthritis is unknown. The goal of this study is to establish the prevalence of midcarpal arthritis in patients with CMC arthritis and/or STT (scaphotrapezotrapezoid) arthritis.
Design and synthesis of ruthenium(II)-bipyridyl-containing polymers (2004)

A series of novel π-conjugated polymers containing ruthenium bipyridine complexes have been synthesized by a cross-coupling reaction and characterized. These polymers exhibit absorption maxima at around 330 - 350 nm (π-π*) and 460-500 nm (MLCT) respectively. They are soluble in common organic solvents and all polymers can be converted into transparent films. We investigated the influence of different donating and acceptor diethynylarenes on the UV/Vis spectra. The oxidation potentials, which have been measured by cyclic- and square-wave voltammetry, show a typical Ru<sup>2+/3+</sup> exhibiting at around + 1.26 V vs. SCE and an additional peak for triphenylamine containing polymers (+ 1.07 V <b>C4c</b>). The polymers were further characterized with photoluminescence measurements. When excited at 442 nm (<b>C2</b>), the polymer showed an emission peak at 690 nm. This peak is attributed to the MLCT states.

Reversible Formation of Polymeric Chains by Coordination of Pentaphosphaferrocene with Silver(I) Cations (2006)

A fragile coordination polymer: The pentaphosphaferrocene [Cp*Fe(η5-P5)] reacts with the AgI salt of the weakly coordinating anion [Al{OC(CF3)3}4]− to yield a polymer comprising cyclo-P5 moieties in an unprecedented 1,2,3-coordination mode (see figure). Analytical data and DFT calculations support the existence of a monomer/dimer/oligomer equilibrium in solution, which is entirely in favor of the monomer at room temperature and shifts to the dimer/oligomer at reduced temperatures.
Revisiting Hrovat’s Semi-Active Tuned Mass Damper (SATMD) (1997)

Abstract This paper examines the effects of actuator dynamics on the performance of a hydraulic semi-active tuned mass damper. The original semi-active tuned mass damper design proposed by Hrovat (1983) is recounted. A consistent model for the actuator dynamics is established. A practical bistate control strategy is then developed for the system. The performance of the SATMD is obtained using numerical simulations and compared to Hrovat’s results. While the work here suggests that a carefully designed semi-active tuned mass damper system can provide structural vibration mitigation for wind loads, seismic loads can saturate the tuned mass damper system.
Comparison of Total Nitrogen by Four Procedures and Sequential Determination of Exchangeable Ammonium, Organic Nitrogen, and Fixed Ammonium in Soil (1988)

Abstract Eight soils were analyzed for total N by: (i) steam distillation of NH 3 yielded after conventional H 2 SO 4 digestion, (ii) HF‐H 2 SO 4 digestion, (iii) HF‐HCl treatment in a microwave system, or (iv) a CHN analyzer. Comparison of results showed that the customary Kjeldahl methods underestimate total N in soils. After determination of exchangeable NH 4 , soil organic matter was destroyed by treatment with a reagent composed of hydrogen peroxide plus pyrophosphate plus NaCl to prevent swelling of clays, buffered at pH 5 to avoid loss of NH 3 . Organic N was calculated as the sum of NH 4 and NO 3 determined in the resulting solution produced during organic matter oxidation. Soil residues were analyzed for fixed NH 4 using the three above mentioned procedures. It was deduced that underestimation of total N given by the customary Kjeldahl method depends on inefficiencies of acid digestion in releasing NH 4 trapped in clay lattices. Values for total N calculated from the sum of exchangeable NH 4 , organic N, and fixed NH 4 are fairly consistent with those determined directly.
Women and Political Knowledge During the 2000 Primaries (2000)

Prior research on political knowledge has found repeatedly that women do not perform as well as men on political affairs questions. The present study analyzed survey responses collected between 14 December 1999 and 8 March 2000 on political knowledge items about the issue positions and backgrounds of candidates Bradley, Gore, and McCain. Even when several sociodemographic variables were controlled for, gender was a significant predictor of political knowledge. Not only were women more likely than men to say they did not know the answer to a question, but they were also more likely to answer incorrectly when giving a substantive response.
Identification of haptoglobin as a natural inhibitor of trypanocidal activity in human serum. (1995)

Trypanosomes are protozoan parasites of medical and veterinary importance. Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense infect humans, causing African sleeping sickness. However, Trypanosoma brucei brucei can only infect animals, causing the disease Nagana in cattle. Man is protected from this subspecies of trypanosomes by a toxic subtype of high density lipoproteins (HDLs) called the trypanosome lytic factor (TLF). The toxic molecule in TLF is believed to be the haptoglobin-related protein that when bound to hemoglobin kills the trypanosome via oxidative damage initiated by its peroxidase activity. The amount of lytic activity in serum varies widely between different individuals with up to a 60-fold difference in activity. In addition, an increase in the total amount of lytic activity occurs during the purification of TLF, suggesting that an inhibitor of TLF (ITLF) exists in human serum. We now show that the individual variation in trypanosome lytic activity in serum correlates to variations in the amount of ITLF. Immunoblots of ITLF probed with antiserum against haptoglobin recognize a 120-kDa protein, indicating that haptoglobin is present in partially purified ITLF. Haptoglobin involvement is further shown in that it inhibits TLF in a manner similar to ITLF. Using an anti-haptoglobin column to remove haptoglobin from ITLF, we show that the loss of haptoglobin coincides with the loss of inhibitor activity. Addition of purified haptoglobin restores inhibitor activity. This indicates that haptoglobin is the molecule responsible for inhibition and therefore causing the individual variation in serum lytic activity.

Percutaneous radiofrequency lesioning of the suprascapular nerve for the management of chronic shoulder pain: a case series (2012)

Effect of nicotine on cerebellar granule neuron development (2001)

To assess the role of nicotinic cholinergic receptors (nAChR) on neuronal maturation, nAChR expression and the direct effects of nAChR activation were examined in cerebellar external granular layer (EGL) precursors isolated in vitro. Treatment of EGL neuroblasts with nicotine elicited a concentration-dependent increase in DNA content and synthesis, implying an increase in cell numbers. Pretreatment of cultures with the nAChR antagonist dihydro-beta-erythroidine (DHBE) attenuated nicotine-induced changes in DNA abundance and synthesis. Furthermore, chronic nicotine treatment for 4-7 days promoted EGL cell survival. Epibatidine but not cytisine stimulated granule neuroblast DNA synthesis and survival. Survival effects mediated by nicotine and epibatidine were attenuated by pretreating cultures with DHBE. Immunocytochemical analysis revealed that EGL neurons possessed alpha3, but not alpha4, nAChR immunoreactivity. Quantitative autoradiography was used to determine which nAChRs are present during the period of granule cell neurogenesis in vivo. On postnatal day 5, the EGL was intensely labelled by [3H]-epibatidine but virtually devoid of [3H]-A85380 binding, suggesting that a high concentration of alpha3 AChRs is present in granule neuroblasts. The pharmacology of [3H]-epibatidine displacement from EGL neurons also suggested an interaction with the alpha3-nAChR subunits. Together these data provide novel evidence that the activation of nAChRs directly affect the development of primary cerebellar neuroblasts and further suggest that the effects are mediated through the alpha3-nAChR subtype.
