STRATEGIC HIGHWAY RESEARCH PROGRAM POTHOLE REPAIR MATERIALS AND PROCEDURES (1993)

As funding for rehabilitation of pavements becomes more scarce, the ability of maintenance agencies to extend pavement service life with patching and other maintenance techniques becomes more critical. The Strategic Highway Research Program has conducted a study of the effectiveness of several pothole patching materials and methods. Eight test sites were installed throughout the United States and Canada, and the performance of the patches was monitored at those sites. The ability to identify good-quality patching materials for use by highway agencies will benefit many agencies, from state departments of transportation to county, city, and municipal streets and roads departments. If agencies can reduce the amount of patch material purchased, as well as the manpower required by increasing the life expectancy of patches, the potential exists to save millions of dollars each year on patching operations. The patchability of an area is determined by a number of factors beyond the control of the average maintenance crew--traffic, underlying support, drainage, climate and so on. However, the quality of patching materials and methods used does appear to affect the durability of patches placed. Certain materials will work better than others under different conditions and have the potential to provide significant cost savings to agencies responsible for the maintenance of asphalt-surfaced pavements.
Sinusoidal Shear Generator for Study of Viscoelasticity (1962)

An apparatus is described in which a pure dynamic shear strain is produced in a small sample of liquid or other material, and the resulting shear stress is measured in the frequency range between 20 and 1000 cps. The shear stress is decomposed into its real and imaginary parts, which yield the shear rigidity and the shear viscosity. Design and working equations are derived. Two liquids are investigated and the data shown. The effect of impurity molecules is discussed, and a possible application to lubrication theory is suggested.
In Vitro Propagation of Cannabis sativa L. Using meta-Topolin (2015)

Cannabis sativa is one of the oldest known domesticated plants belonging to the family Cannabaceae. It is extensively cultivated throughout the world for its psychoactive properties, durable fiber and seeds. The plant is reported to have several medicinal properties. The present study describes a simple, efficient and one step regeneration system for rapid axillary shoot proliferation and in vitro rooting of C. sativa nodal explants using meta-Topolin (mT), an aromatic natural cytokinin. The highest shoot proliferation frequency was obtained from nodal explants cultured on Murashige and Skoog (MS) basal salts supplemented with 0.5 mg l–1 meta-topolin (mT) generating an optimal number of shoots with suitable morphological features. Shoots multiplied on the same medium for two subcultures of three weeks each, were able to induce healthy roots. Regenerated plantlets were successfully acclimatized and hardened off inside the culture room and then transferred to a greenhouse with 100% survival rate.
Identification of the murine coronavirus p28 cleavage site (1995)

Mouse hepatitis virus strain A59 encodes a papain-like cysteine proteinase (PLP-1) that, during translation of ORF1a, cleaves p28 from the amino terminus of the growing polypeptide chain. In order to determine the amino acid sequences surrounding the p28 cleavage site, the first 4.6 kb of murine hepatitis virus strain A59 ORF1a was expressed in a cell-free transcription-translation system. Amino-terminal radiosequencing of the resulting downstream cleavage product demonstrated that cleavage occurs between Gly-247 and Val-248. Site-directed mutagenesis of amino acids surrounding the p28 cleavage site revealed that substitutions of Arg-246 (P2) and Gly-247 (P1) nearly eliminated cleavage of p28. Single-amino-acid substitutions of other residues between P7 and P2' were generally permissive for cleavage, although a few changes did greatly reduce proteolysis. The relationship between the p28 cleavage site and other viral and cellular papain proteinase cleavage sites is discussed.

Current on an Infinitely-Long Carbon Nanotube Antenna Excited by a Gap Generator (2006)

The current on an infinitely-long carbon nanotube (CN) antenna fed by a delta-gap source is studied using a Fourier transform technique. The CN is modeled as an infinitely-thin tube characterized by a semi-classical conductance, appropriate for the frequencies of interest considered in this work. The CN's current is compared with the current on solid and tubular copper antennas having similar or somewhat larger radius values. It is found that for radius values on the scale of nanometers, CNs exhibit smaller losses than cylindrical copper antennas having the same dimensions, assuming the bulk value of copper conductivity. When one assumes a more realistic, reduced copper conductivity that accounts for the nanoscopic radius of the wire, the advantage of the CN over a metallic wire is increased.

Leydig cells secrete factors which increase vascular permeability and endothelial cell proliferation (1996)

Adult intact control rats, and animals treated with human chorionic gonadotrophin (hCG) or with ethane dimethane sulphonate (EDS) to deplete Leydig cells, were injected with bromodeoxyuridine (BrdU) to label proliferating cells. Apoptotic cells were visualized by in-situ end labelling (ISEL) of fragmented DNA. Three per cent of testicular endothelial cells were labelled with BrdU and few were apoptotic in intact testes. The BrdU endothelial cell labelling index was increased by hCG-treatment and decreased in Leydig cell-depleted testes. Immunohistochemical staining showed that Leydig cells and testicular macrophages contain immunoreactive vascular endothelial growth factor (irVEGF). The ability of testicular cells to stimulate angiogenesis was studied further by transplanting interstitial cells or seminiferous tubule segments under the kidney capsule. A prominent vascular network was observed around interstitial cell grafts, but not around tubule grafts. Treatment of transplanted rats with human chorionic gonadotrophin (hCG, 50 i.u.) resulted in an accumulation of PMN-leukocytes and an increase in vascular permeability in the remaining testis and in interstitial cell grafts. Interstitial cells from Leydig cell-depleted (EDS-treated) testes were also transplanted under the kidney capsule. This type of graft caused only a discrete stimulation of angiogenesis, and there was no increase in vascular permeability around the graft after hCG treatment. It is suggested that Leydig cells secrete angiogenic factors and that they are the source of the inflammation mediator(s) produced in the testis after hCG treatment. The high proliferation rate in endothelial cells suggests continuous remodelling of the testicular microvasculature, but the functional significance of this remains unknown.
Catalysis by design: Well-Defined Aluminum tetra-coordinated Surface Ligand for Catalytic applications (2018)

The main target of this thesis is the design of a new aluminum-based surface ligand with low coordination and expected high acidity. These new supports will serve for the immobilization of different organometallic complexes with the surface organometallic chemistry (SOMC). The resulting molecular like species will be used for various catalytic applications including alkane metathesis, olefin metathesis and polymerization. The first chapter is an introduction to the field of catalysis, more specifically, surface organometallic with a summary of its concept and the main examples cited for the immobilization of transition metal complexes on different oxide surfaces (silica, silica-alumina and alumina). This chapter presents, as well, an overview of the use of the aluminum alkyls compounds and their immobilization on a surface for the generation of various aluminum based surfaces. The Second chapter details the reaction involving the grafting of the monomeric triisobutylaluminum on SBA-15700. The final structures and the mechanism involved were determined by various characterization techniques including FT-IR, 1H and 13C solid-state NMR, and DFT calculations. The reaction leads mainly to a bipodal [(≡Si-O-Si≡)(≡SiO)2AliBu] species with 3 differents types of alumium coordinations (AlIV, AlV and AlVI) along with 37% [≡Si-H] and 63% [≡Si-ibu]. The Third chapter describes the reaction of a highly dehydroxylated SBA-15 with a trimeric di-isobutyl aluminum hydride, [i-Bu2AlH]3 is investigated by both experiments and DFT calculations. The mechanism involves very different pathway comparing to the TIBA case where only AlIV-isobutyl were generated. Further β-H elimination leads to an well-defined AlIV hydride analog [(≡Si-O-Si≡)(≡SiO)2Al-H]. The later shows good activity in ethylene polymerization reaction with the formation of HDPE. The Fourth Chapter deals with the immobilization of the 2nd generation Hoveyda-Grubbs (HGII) catalyst onto well-ordered 2D hexagonal (SBA15), and 3D fibrous (KCC-1) mesostructure silica containing tetra-coordinated [Al-H] sites. The resulting catalysts show high activity in the non-functionalized olefin metathesis of propene. The results clarified that the supported catalyst prepared using KCC-1 shows better performance than the one prepared using SBA-15 due to the diffusion effect; and exhibits much higher activity than the HG-II itself, in homogeneous phase. The Fifth chapter of this thesis presents the formation of tetra-coordinated [(≡Si–O–Si≡)(≡Si– O)2Al–OH], through [Al-H] oxidation using N2O. The synthesis was detailed and the grafted species were fully characterized. This new site will serve as anchoring site for the immobilization of the tungsten based complexes. Its activity was evaluated in the propane metathesis reactions, where a TON of 800 was obtaine, which is the highest value obtained for a SOMC monometallic catalyst. Finally, the last chapter will present the thesis conclusion including most of the ongoing applications related to the use of those new surfaces.
Study of the laser lift-off technology of GaN films from sapphire substrates (2005)

Gallium Nitride films grown on sapphire substrates were successfully separated by laser radiation. The absorption of the 248 nm radiation by the GaN at the interface results in rapid thermal decomposition of the interfacial layer, yielding metallic Ga and N/sub 2/ gas. The substrate can be easily removed by heating above the Ga melting point of 30/spl deg/C. Atomic force microscopy, X-ray diffraction and Photoluminescence of GaN before and after lift-off process have been performed, which demonstrated that the separation and transfer process do not alter the structural quality of the GaN films. And further discussions on the threshold energy and crack-free strategies of laser lift-off process have also been presented.
[Comparison of serum immunoglobulin levels in patients with alveolar and cystic echinococcosis]. (1990)

Serum IgG, IgA and IgM levels of 91 patients with alveolar echinococcosis and 83 patients with cystic echinococcosis were compared with 104 healthy adults as controls by single radial immunodiffusion. The mean IgG, IgA and IgM concentrations in patients with alveolar echinococcosis and the mean IgG and IgM levels in patients with cystic echinococcosis were found to be significantly higher than those of the normal controls. The mean IgG, IgA and IgM levels in patients with alveococcosis were 510 +/- 413.06, 389.45 +/- 433.42 and 313.48 +/- 255.19, while those in cystococcosis were 308.36 +/- 339.24, 329.61 +/- 319 and 266.68 +/- 255.68 respectively. The geometric mean of IgG and IgM levels in patients with alveococcosis was 1.67 and 1.25 times that in cystococcosis. 76.9% of alveococcosis patients had IgG levels reaching 200 IU/ml or above, being significantly higher than that in the cystic hydatidosis (50.6%). 93.4% of alveolar echinococcosis cases showed elevated IgM levels up to 100 IU/ml or more, being also significantly higher than that of cystic echinococcosis cases (78.3). Statistically, there was significant correlation between IgG concentration and ELISA antibody titre.
Performance of tornado-type wind turbines with radial inflow supply (1982)

Wind tunnel tests were conducted for the performance of tornado-type wind turbines (TTWT) with radial inflow supply from incoming wind. It was shown that the radial inflow supply was necessary for intensifying a vortex in the wind collecting tower and, consequently, for enhancing the power efficiencies, C /SUB p/, of the wind turbines. Maximum C /SUB p/ (based on turbine disk area) of 3.8 and 9 was obtained for circular- and spiral-shaped towers, respectively, as compared to 0.4 for conventional windmills. With the radial inflow supply, the maximum C /SUB p/ was increased about 100% for the circular model but only 15-30% for the spiral model since the spiral model provides the inflow effect by itself.
An Aspect-Oriented With BIP Components for Better Crosscutting Concerns Modernization in IOT Applications (2018)

The complexity of Internet of things applications is inherited from the nature of Internet of things components interactions, construction, and implementation of non-functional requirements (crosscutting concerns). Managing such complexity is extremely difficult since implementing crosscutting concerns tend to be spread out and tangled across core IoT architecture. In this paper, we propose an aggregated model of aspect orientation paradigm and BIP components to provide better means to deal with these complexities. Our proposed model provides IoT high level abstractions which gathers relevant contextual properties pertaining to the environment of IoT interactions. We integrate BIP components to generate solutions for a complex tracking and tracing logic of interaction characteristics that might provide better separation of concerns and modularization.
Treatment of vitiligo with topical methoxsalen and blacklite (1969)

Fourteen of 15 vitiligo patients responded to the topical use of methoxsalen and subsequent exposure to long-wave ultraviolet light. Three of the subjects showed complete repigmentation. Adverse reactions were prevented by using a controlled energy source with a light emission pattern corresponding to the biologic action spectrum of the photosensitizer. As a delayed 48 to 72 hour erythema was produced, only weekly treatments were necessary. Repigmentation began after two to ten treatments and migrated out from the hair follicles or advanced in from the borders of the vitiliginous areas. This repigmentation was associated with the migration of Dopa-positive melanocytes into the treated areas.
Analysis and design of an isolated single-stage converter achieving power-factor correction and fast regulation (1999)

This paper presents the analysis and design of an isolated single-stage converter achieving high-power-factor correction and fast regulation. By using the technique suggested by Wu et al., a buck-boost converter and a flyback converter can be integrated to form the discussed converter. The buck-boost semistage working in the discontinuous conduction mode (DCM) functions as a power-factor corrector, and the flyback semistage operating in the DCM is a voltage regulator which is controlled, theoretically, to be independent of load variation. An approximated small-signal model of the converter operating in the DCM is developed. Design of a peak-current feedback loop with an optimal proportional integral controller is also presented. A prototype is implemented to verify that the analysis and design are effective and feasible.
Differential effects of C- and N-terminal substance P metabolites on the release of amino acid neurotransmitters from the spinal cord: potential role in nociception (1990)

Extensive evidence implicates Substance P [SP(1-11)] as a primary afferent neurotransmitter or modulator of nociceptive information, and there is increasing evidence that the excitatory amino acids aspartate (Asp) and glutamate (Glu) may also act as nociceptive neurotransmitters. We have previously demonstrated that nociceptive stimulation (metatarsal injection of formalin) caused a tetrodotoxin (TTX)-sensitive release of Asp and a TTX-insensitive release of Glu from the dorsal spinal cord. We have also shown release of Asp and Glu following the direct infusion of SP(1-11), suggesting that formalin-induced Asp or Glu changes could be secondary to an initial release of SP(1-11). In contrast to nociception, pretreatment with TTX, reported here, had no effect on the SP(1-11)-induced release of Asp, suggesting a presynaptic mechanism. Behavioral experiments, in both our laboratory, and others, now suggest that the N-terminal products of SP metabolism play a distinct role in the modulation of SP(1-11) nociception, possibly through an interaction with an opiate receptor. To test the hypothesis that N- and C-terminal fragments of SP produce opposite effects on biochemical events potentially involved in nociception, we compared the effects of infusion of the N-terminal metabolite SP(1-7) and the C-terminal metabolite SP(5-11) on changes in the ECF concentration of amino acids in the spinal cord as a measure of their apparent release, using microdialysis. Intradiaylsate infusion of SP(5-11) increased the release of Asp, Glu, asparagine (Asn), glycine (Gly), and taurine (Tau). The changes in Asp, Glu, and Tau were similar in direction and magnitude to changes produced by SP(1-11) or formalin injection, further supporting the hypothesis that the C-terminal is responsible for the nociceptive effects of SP(1-11). In contrast, infusion of SP(1-7) significantly decreased the release of Asn, Tau, Glu, and Gly. This inhibition of amino acid release is consistent with the hypothesis that N-terminal metabolites produce opposite effects to those of C-terminal metabolites of SP(1-11). The decreases in Glu, Asn, Gly, and Tau following SP(1-7) infusion were significantly reduced by i.p. or intradialysate naloxone. Systemic naloxone had no significant effects on the SP(5-11)-induced amino acid changes; however, it did inhibit the SP(1-11)-induced increase in Asp and Glu. Intradialysate naloxone had no effect on the SP(1-11)-induced increases.(ABSTRACT TRUNCATED AT 400 WORDS)
A Comparison of Tree Trunk Injection and Implantation of Zinc Capsules for Correction of Zinc Deficiency (1980)

Zinc sulfate was applied to pecan tree trunks through implants and pressure trunk injection. Small amounts of chelated Zn solution were also injected by means of small pressurized cartridges. The most effective and efficient method for rapid correction of Zn deficiency of pecan when measured by leaflet Zn concentration was by pressure trunk injection using 8 liters per tree of solution containing 1 g of ZnSO4/2.5 cm of trunk circumference. Pressure trunk injection was the only method which produced adequate leaflet Zn concentrations in September. Implants of equivalent amounts of ZnSO4 increased leaflet Zn over the control by September, but leaflets were still Zn deficient and phytotoxicity of trunk cambium tissue occurred. Pressurized cartridges were ineffective due to the small amount of Zn provided.
Enhanced line-based intra prediction with fixed interpolation filtering (2011)

In this paper, a novel intra prediction algorithm, named enhanced line-based intra prediction (ELIP), is proposed to improve the traditional intra prediction methods for image/intra-frame coding. Different from the existing schemes where the interpolation filtering only depends on the intra prediction mode, in the proposed ELIP, the linear filtering coefficients are further refined by imposing both mode and position dependencies. For each intra prediction mode and each position within one block, a set of linear filtering coefficients are obtained from off-line training using the least square method. The proposed algorithm has been implemented in the latest ITU-T VCEG KTA software. Experimental results demonstrate that, compared with the intra coding scheme of KTA with new intra coding tool enabled, up to 0.44dB additional coding gain is achieved by the proposed method, while keeping applicable computational complexity for practical video codecs.
