Studies on electrolytically coloured aluminium (1990)

Attractive coloured finishes can be imparted to aluminium, by anodising it and subsequently subjecting it to ac electrolysis in metal salt solutions. Conventional process involves H2S04 anodising, subsequent H3P04 anodising and ac electrolysis. Alternately one can use a two step process13; omitting H3P04 anodising. A new two step process involving H3PO4 anodising and ac electrolysis is described.13; It is shown here that the colour of electrolytically coloured aluminium is due to optical interference. Optical models for the two step and three step processes are proposed to explain the colours.
Micro-actuated small-scale spherical retroreflector for free space optical communications (2006)

Extension of peripheral nonperfusion in eyes with retinal vein occlusion during intravitreal dexamethasone treatment (2018)

Using 200° wide-field fluorescein angiography, the ischaemic index was shown to remain stable during dexamethasone treatment. This finding was consistent in ischaemic as well as in nonischaemic conditions.
Edge-preserving in generalized smoothing of signals and images (2002)

Under the generalized smoothing of a signal or image, a wider class of operations is understood than the plain suppression of noise. A variational approach to the generalized edge-preserving smoothing is considered on the basis of treating the sought-for result of processing as the minimum point of an objective function.
Ferromagnetic Inks Facilitate Large Scale Paper Recycling and Reduce Bleach Chemical Consumption (2013)

Deinking is a fundamental part of paper recycling. As the global paper consumption rises and exceeds even the annual paper production, recycling of this raw material is of high importance. Magnetic ink based on carbon coated magnetic nanoparticles enables an alternative approach to state of the art paper deinking. Magnetic deinking comprises three steps (preselection, washing, and magnetic separation of fibers). Preseparation of printed from nonprinted scraps of paper is feasible and reduces the paper mass which has to be fed into a deinking process. A consecutive washing process removes surficial magnetic ink that can be collected by application of a permanent magnet. Still, printed parts are subjected to a further continuous magnetic deinking step, where magnetic and nonmagnetic paper fibers can be separated. Magnetic deinking of a model print allows recovery of more than 80% of bright fibers without any harsh chemical treatment and the re-collection of more than 82% of magnetic ink.

Role of angiogenesis inhibitors in acute myeloid leukemia. (2002)

Neovascularization is increasingly recognized as an important factor in the pathogenesis of hematologic malignancies as well as solid tumors. The complex interactions between several cell types and numerous cytokine mediators suggest the involvement of autocrine and paracrine signaling mechanisms. Vascular endothelial growth factor (VEGF) in particular is critical to both stimulation of leukemic growth and proliferation of endothelial cells. Tyrosine kinase receptors specific for certain growth factors represent attractive target molecules for anticancer therapy. SU5416 is a competitive inhibitor of VEGF receptor subtypes VEGFR-1 and VEGFR-2 and stem cell factor receptor c-kit. Preclinical evidence shows that SU5416 effectively inhibits VEGF-induced endothelial cell proliferation and slows growth of subcutaneous solid tumor xenografts. This agent is in late-stage clinical trials in patients with solid tumors, and a Phase 2 study was recently initiated to evaluate its utility in the treatment of acute myeloid leukemia. In this Phase 2 study, investigators are seeking to determine the response rate to the antiangiogenic agent SU5416. Translational research in this study is intended to aid our understanding of the precise mechanisms by which SU5416 affects acute myeloid leukemia cells and the bone marrow microenvironment.
Inheritance of Tillering in a Winter Wheat Population (1995)

Tillers are an important component of wheat ( Triticum aestivum L. emend. Thell.) grain yield, yet there is uncertainty in the literature about improving yield by selecting for tiller number. The objectives of this study were to estimate the heritability of tiller number, to quantify genotype × environment (G × E) interaction, and to assess tiller number as an indirect selection criterion. We measured tiller number at five growth stages, grain yield, and kernel size in 92 soft red winter wheat F 4 lines in 1987 and in their bulk F 5 progeny at two planting dates in 1988. Heritability ( h 2 ) of tiller number at Feekes growth stages 2, 4, 7, 10.1, and 11.2 in a single environment ranged from 0.05 to 0.60. When G × E interaction was accounted for in a combined analysis, however, heritability estimates were much lower, ranging from −0.14 to 0.19. Genotype rank changes were common among pairs of environments, though in certain cases, scale differences predominated. Tiller number at growth stage 10.1 was highly correlated with yield ( r = 0.58, P < 0.01) and had higher heritability ( h 2 = 0.19) than yield ( h 2 = 0.05), and thus, we predict a higher response (36%) to indirect selection than to direct selection for yield itself. Indirect selection for tiller number with visual keys would be most appropriate in early generations when direct yield assessment is difficult, followed by direct selection for yield in later generations.

Production of Chlorflavonin, an Antifungal Metabolite of <i>Aspergillus candidus</i> (1970)

Production of chlorflavonin, a new antifungal antibiotic, by strains of Aspergillus candidus is described. Two wild strains of the fungus had distinctly different chlorflavonin-producing capabilities. One strain produced 25 mug of chlorflavonin per ml per 4 to 5 days in a pilot scale fermentor with stirring, using a medium containing corn steep liquor and glucose. Production of antibiotic was favored by high rates of agitation-aeration. Crude chlorflavonin was extracted from the whole brew with a hydrocarbon solvent and then purified by recrystallization from benzene and petroleum ether. The overall yield from fermentation brew to pure product was 50%.

Nitroxide radicals protect cultured rat embryos and yolk sacs from diabetic‐induced damage (2007)

In diabetic culture medium, oxidative damage is higher in the malformed rat embryos compared to those without anomalies; the nitroxide provides protection against diabetes-induced teratogenicity in a dose-dependent manner. The yolk sac damage, apparently caused by the same mechanism, might be an additional contributor to the embryonic damage observed in diabetes.
The Impact of Vectorization on Erasure Code Computing in Cloud Storages - A Performance and Power Consumption Study (2015)

Erasure code storage systems are becoming popular choices for cloud storage systems due to cost-effective storage space saving schemes and higher fault-resilience capabilities. Both erasure code encoding and decoding procedures are involving heavy array, matrix, and table-lookup compute intensive operations. Multi-core, many-core, and streaming SIMD extension are implemented in modern CPU designs. In this paper, we study the power consumption and energy efficiency of erasure code computing using traditional Intel x86 platform and Intel Streaming SIMD extension platform. We use a breakdown power consumption analysis approach and conduct power studies of erasure code encoding process on various storage devices. We present the impact of various storage devices on erasure code based storage systems in terms of processing time, power utilization, and energy cost. Finally we conclude our studies and demonstrate the Intel x86's Streaming SIMD extensions computing is a cost-effective and favorable choice for future power efficient HPC cloud storage systems.
Short Peptides with Induced β-Turn Inhibit the Interaction between HIV-1 gp120 and CD4 (2001)

To identify novel peptides that inhibit the interaction between human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein gp120 and CD4, we constructed a targeted phage-displayed peptide library in which phenylalanine and proline were fixed at the fourth and sixth positions, respectively, because Phe43 and the adjacent beta-turn of CD4 are critical for interaction with gp120. Two synthetic peptides were selected after three rounds of biopanning against gp120, and one of them, G1 peptide (ARQPSFDLQCGF), exhibited specific inhibition of the interaction between gp120 and CD4 with an IC(50) of about 50 microM. Structural analysis using NMR demonstrated that G1 peptide forms a compact cyclic structure similar to the CD4 region interacting with gp120. Two derivatives of G1 peptide, a linear hexameric peptide (G1-6) and a cyclic nonameric peptide (G1-c), were synthesized based on the structure of the G1 peptide. Interestingly, they showed higher inhibitory activities than did G1 peptide with IC(50)'s of 6 and 1 microM, respectively. Thus, this study might provide a new insight into the development of anti-HIV-1 inhibitors.
Proton radiation testing of laser optical components for NASA Jupiter Europa Orbiter Mission (2011)

The Jupiter Europa Orbiter (JEO) is NASA's element of the joint Europa Jupiter System Mission (EJSM). Based on current trajectories, the spacecraft will spend a significant amount of time in the Jovian radiation belts. Therefore, research endeavors are underway to study the radiation effects on the various parts and components needed to implement the instruments. Data from these studies will be used for component selection and system design to ensure reliable operation throughout the mission duration. The radiation environment en route to Jupiter is nothing new for NASA designed systems, however, the long durations orbiting Jupiter and Europa present new challenges for radiation exposure. High-energy trapped electrons and protons at Jupiter dominate the expected radiation environment. Therefore, most of the initial component level radiation testing is being conducted with proton exposure. In this paper we will present in-situ monitoring of the optical transmission of various laser optical components during proton irradiation. Radiation induced optical attenuation of some components is less than would be expected, based on the authors experiences, and is attributed to the interaction of the protons with the materials. The results are an encouraging first step in screening these optical materials for spaceflight in a high radiation environment.
Protecting travelers against infections (1996)

Every year thousands of Americans travel abroad and risk encountering diseases to which they are not normally exposed. With pretravel counseling from their physician, travelers can substantially reduce or eliminate the risk of many common travel-related infectious diseases. Patients should be informed about required and recommended vaccinations, chemoprophylaxis and other preventive measures, and strategies for self-treatment, should an infection arise during travel. Up-to-date travel health resources, including sites on the World Wide Web, can assist physicians in advising patients about immunizations and other preventive measures recommended for travel to endemic areas.
Thermostatic tissue platform for intravital microscopy: ‘the hanging drop’ model (2006)

Intravital microscopy imposes the particular problem of the combined control of the body temperature of the animal and the local temperature of the observed organ or tissues. We constructed and tested, in the rat ileum microcirculation preparation, a new organ-support platform. The platform consisted of an organ bath filled with physiological solution, and contained a suction tube, a superfusion tube, an intestine-support hand that was attached to a micromanipulator and a thermometer probe. To cover the intestine we used a cover glass plate with a plastic ring glued on its upper surface. After a routine procedure (anaesthesia, monitoring and surgery), the intestine segment (2-3 cm long) was gently exteriorized and placed on the 'hand' of the organ support. A small part of the intestine formed a small 'island' in the bath that was filled with physiological salt solution. The cover glass was secured in place. The physiological salt solution from the superfusion tube, which was pointed to the lower surface of the cover glass, formed a 'hanging drop'. The objective of the microscope was then immersed into distilled water that was formed by the cover glass plastic ring. The 'hanging drop' technique prevented any tissue quenching, ensured undisturbed microcirculation, provided for stable temperature and humidity, and permitted a clear visual field.
Optimal Asymmetric Binary Quantization for Estimation Under Symmetrically Distributed Noise (2013)

Estimation of a location parameter based on noisy and binary quantized measurements is considered in this letter. We study the behavior of the Cramer-Rao bound as a function of the quantizer threshold for different symmetric unimodal noise distributions. We show that, in some cases, the intuitive choice of threshold position given by the symmetry of the problem, placing the threshold on the true parameter value, can lead to locally worst estimation performance.
Don't Give Up on Distributed File Systems. (2007)

Wide-area distributed applications often reinvent the wheel for their storage needs, each incorporating its own special-purpose storage manager to cope with distribution, intermittent failures, limited bandwidth, and high latencies. This paper argues that a distributed file system could provide a reusable solution to these problems by coupling a standard interface with a design suited to widearea distribution. For concreteness, this paper presents such a file system, called WheelFS, which allows applications to control consistency through the use of semantic cues, and minimizes communication costs by adhering to the slogan read globally, write locally. WheelFS could simplify distributed experiments, CDNs, and Grid applications.

PREPARATION AND STUDY OF CERAMIC MEMBRANE REACTOR FOR HYDROGEN SULFIDE CATALYTIC DECOMPOSITION (2017)

The paper studies a number of alumina ceramic membrane catalysts of various design and composition for high temperature H 2 S decomposition. The design of two types of catalytic membranes used consists of sandwich-like structure including (1) “catalytic layer”/”membrane support”/”membrane layer” and (2) “catalytic layer”/”membrane support”/”intermediate layer”/”membrane layer”. The paper describes: the physical and chemical properties (pore structure, specific surface area and phase composition) of membrane supports and membrane layers calcined at different temperatures; the methods of various composition membrane reactors preparation; the data on membrane permeability on H 2 and H 2 S; the test results of prepared membranes in the reaction of H 2 S decomposition. The introduction of La 2 O 3 modifying additions in a membrane layer is shown to lead to the increase of thermal stability of a membrane. The effective diameter of pores of membrane layer having 5%La 2 O 3 -γ-Al 2 O 3 composition and calcined at 900ºC is three times lower than of the unmodified γ-Al 2 O 3 . The presence of pure γ-Al 2 O 3 phase in the modified membrane layer is observed while the δ-Al 2 O 3 phase is formed in the unmodified sample. The pore structure and the thickness of the membrane layer are demonstrated to significantly influence permeability of H 2 and H 2 S. There has been observed a significant improvement of the catalytic activity in the H 2 S decomposition reaction compared with a granulated catalyst because the separation coefficient of H 2 /H 2 S is higher than 2.5. It has been determined that the introduction an intermediate layer, which has different effective pore diameter in comparison with the membrane layer, to the membrane composition increases significantly the H 2 S conversion. The membrane reactor consisting of the membrane layer (6 m thickness, pore diameter 45 Å) and the intermediate layer (9 m thickness, pore diameter 110 Å) has been found to exhibit maximal efficiency in the H 2 S decomposition reaction. The H 2 S conversion reaches 65% at 900ºC on the membrane catalyst of optimal composition.
Laboratory‐Determined Transport Properties of Core From the Salton Sea Scientific Drilling Project (1988)

Two cores from the Salton Sea Scientific Drilling Project have been studied in the laboratory to determine electrical resistivity, ultrasonic velocity, and brine permeability at pressures and temperatures close to estimated borehole conditions. Both samples were siltstones; the first sample was from 1158‐m depth, and the other was from 919‐m depth. A synthetic brine with 13.6 weight percent NaCl, 7.5 weight percent CaCl 2 , and 3.2 weight percent KCl was used as a pore fluid. The dry bulk density of the first sample was 2.44 Mg m −3 with an effective porosity of 8.7%. The second sample had a dry bulk density of 2.06 Mg m −3 with an effective porosity of 22.2%. At the midplane of the first sample, electrical impedance tomography was used to map the spatial variation of resistivity during the experiment. Also, at the midplane of both samples, ultrasonic tomography was used to map the spatial variation of P wave velocity. In addition, resistivity was measured with six pairs of electrodes along the sample axis. Both samples showed a strong anisotropy in resistivity and ultrasonic velocity measured perpendicular and parallel to the sample axis. The brine permeability of the first sample decreased from 5 μD to about 1.6 μD during the experiment. The second sample permeability had the same trend, but the permeability values were about 3 orders of magnitude larger. The second sample was subjected to temperatures and pressures exceeding those experienced in situ. Permeability, resistivity, and ultrasonic velocity of this sample showed a discontinuous change just beyond these in situ conditions. This discontinuity implies a structural change in the rock under conditions which would be found below its origin depth in the borehole. A model is proposed to explain the observed velocity anisotropy and variations in velocity, electrical resistivity anisotropy, and permeability with effective depth. When in situ stress is released, microcracking may occur along grain boundaries preferentially oriented parallel to bedding. This microcracking controls velocity and resistivity anisotropy at room conditions. When pressure and temperature are restored, competing effects of compaction and thermal softening of the minerals cause a reversal in the anisotropy. At temperatures and pressures above those at in situ conditions, thermal fracturing or geochemical alteration along grain boundaries causes a discontinuous change in sample physical properties.
