    Studies of perennial peanut (Arachis glabrata Benth.) suggest its hay and haylage have greater levels of rumen undegraded protein (RUP) than other legume forages such as alfalfa (Medicago sativa L.). Greater RUP can result in more efficient nitrogen utilization by ruminant animals with positive economic and environmental effects. We sought to determine whether, like red clover (Trifolium pretense L.), perennial peanut contains polyphenol oxidase (PPO) and PPO substrates that might be responsible for increased RUP. Perennial peanut extracts contain immunologically detectible PPO protein and high levels of PPO activity (>100 nkatal mg(-1) protein). Addition of caffeic acid (PPO substrate) to perennial peanut extracts depleted of endogenous substrates reduced proteolysis by 90%. Addition of phenolics prepared from perennial peanut leaves to extracts of either transgenic PPO-expressing or control (non-expressing) alfalfa showed peanut phenolics could reduce proteolysis >70% in a PPO-dependent manner. Two abundant likely PPO substrates are present in perennial peanut leaves including caftaric acid. Perennial peanut contains PPO and PPO substrates that together are capable of inhibiting post-harvest proteolysis, suggesting a possible mechanism for increased RUP in this forage. Research related to optimizing the PPO system in other forage crops will likely be applicable to perennial peanut. Published 2013.

    The Imaging IR Limb Sounder (IRLS) is one of the two instruments planned on board of the candidate Earth Explorer Core Mission PREMIER. PREMIER stands for PRocess Exploration through Measurements of Infrared and Millimetre-wave Emitted Radiation. PREMIER went recently through the process of a feasibility study (Phase A) within the Earth Observation Envelope Program. Emerging from recent advanced instrument technologies IRLS shall, next to a millimetre-wave limb sounder (called STEAMR), explore the benefits of three-dimensional limb sounding with embedded cloud imaging capability. Such 3D imaging technology is expected to open a new era of limb sounding that will allow detailed studies of the link between atmospheric composition and climate, since it will map simultaneously fields of temperature and many trace gases in the mid/upper troposphere and stratosphere across a large vertical and horizontal field of view and with high vertical and horizontal resolution. PREMIER shall fly in a tandem formation looking backwards to METOP's swath and thereby improve meteorological and environmental analyses.

    Conversion of polymers and non-polymeric organic molecules from insulating to semiconducting materials as an effect of energetic ion implantation is an established fact. Formation of nano-clusters enriched with carbonaceous materials are made responsible for the insulator-semiconductor transition. Conduction in these implanted materials is observed to follow variable range hopping (VRH) mechanism. Poly(2,6-dimethyl phenylene oxide) [PPO] compatible in various proportion with polystyrene is used as a high thermal resistant insulating polymer. PPO has been used for the first time in the ion implantation study

    Bio-energy is renewable energy made from plant. Biomass-based energy sources are potentially CO2 neutral and recycle the same carbon atoms. In order to reduce pollution caused by fossil fuel combustion either for mechanical or electrical energy generation, the performance characteristic of purified palm oil blends are analyzed at various ratios. Bio-energy, Pure Plant Oil, represent a sustainable solution.A generator has been modified due to adapt the viscosity ofblended fuel, PPO - diesel, by pre-heating. Several PPO - diesel composition and injection timing were tested in order to investigate the characteristic of mixed fuel with and without pre-heating. The term biofuel refers to liquid or gaseous fuels for the internal combustion engines that are predominantly produced fro m biomass. Surprising result showed that BSFC of blended PPO - diesel was more efficient when injection timing set more than 15° BTDC. The mixed fuel produced power with less mixed fuel even though the calorie content of diesel is higher than PPO. The most efficient was 20% PPO in diesel with BSFC 296 gr fuel / kwh rather than 100% diesel with BSFC 309 gr fuel / kwh at the same injection timing 18° BTDC with pre-heating. The improvement of BSFC is caused by heating up of mixed fuel which it added calorie in the mixed fuel. Therefore, the heating up of blended PPO - diesel is not only to adapt the viscosity but also improving the efficiency of fuel usage representing by lower BSFC. In addition, torque of the 20% PPO was also as smooth as 100% diesel representing by almost the same torqueat injection timing 15° BTDC.

    Inactivation effect of pulsed electric field (PEF) on polyphenol oxidase (PPO) and lipoxygenase (LOX) was investigated using a laboratory PEF system with a coaxial treatment chamber. Circular dichroism (CD) and fluorescence analysis were used to study the conformation change of the protein. The experimental results show that PPO and LOX can be effectively inactivated by the PEF treatment. Inactivation effect of PPO and LOX increases with the increase in the applied electric strength and the treatment time. Activity of PPO and LOX can be reduced by 60.3% and 21.7% at 20 kV x cm(-1) after being treated for 320 micros respectively. The decrease of the negative peaks (208 and 215 nm in PPO spectra, 208 nm and 218 nm in LOX spectra) in CD spectra of PPO and LOX shows that PEF treatment caused a loss of alpha-helix and increase in beta-sheet content, indicating that conformation changes occur in the secondary structure of PPO and LOX enzyme. This effect was strengthened as the applied electric field increased: alpha-helical content of PPO and LOX was 56% and 29% after being treated at 8 kV x cm(-1), however, when the electric field was increased up to 20 kV x cm(-1), alpha-helical content of PPO and LOX decreased to 21% and 16% respectively. The decrease rate of alpha-helix and increase rate of beta-sheet in PPO are higher than LOX, indicating that the second conformation of PPO is less resistant to PEF treatment than LOX. The fluorescence intensity of LOX increases after PEF treatment. At the same time, increasing the applied pulsed electric field increases the fluorescence intensity emitted. Fluorescence measurements confirm that tertiary conformation changes occur in the local structure of LOX. However the possible mechanism of the conformation change induced by the PEF treatment is beyond the scope of the present investigation.

    Fernandes Neto, Jose Mari; Hamada, Margarida Mizue; Duarte, Celina Lopes; Mesquita, Carlos Henrique de

    2005-01-01

    Samples containing PPO (1%, g/mL), diluted in toluene, were irradiated in a 60 Co irradiator (6.46 kGy/h) at different doses. The PPO concentration decay bi-exponentially with the dose, generating the degradation products: benzoic acid, benzamide and benzilic alcohol. The liquid scintillator system was not sensitive to the radiation damage until 20 kGy. Otherwise, the pulse height analysis showed that doses between 30 and 40 kGy generated significant loss of quality of the sensor (scintillating liquid) and the light yield was reduced in half with the dose of (34.04 ± 0.80) kGy. This value was confirmed by the photopeak position analysis that resulted in D1/2 = (31.7 ± 1.4) kGy. The transmittance, at 360 nm, of the irradiated solution decreased exponentially. The compartmental model using five compartments (fast decay PPO, slow decay PPO, benzamide, benzoic acid and benzilic alcohol) was satisfactory to explain the decay of the PPO in its degradation products as a function of the dose. The explanation coefficient r2 = 0.985636 demonstrates that the model was capable to explain 98.6% of the experimental variations. The energies involved in the chemical reactions were w = (0.239 ± 0.031) eV/damage (fast decay) and w (1.834 ± 0.301) eV/damage (slow decay). (author)

    1984-01-01

    2,5-diphenyloxazole (PPO) has been proposed as a wavelength shifter for Cherenkov counting. Since PPO is not incorporated with water, we have introduced the fluor into water in the form of micelle using a PPO-ethanol system. This technique makes it possible to obtain a high Cherenkov counting efficiency under stable sample conditions, attributed to the proper spectrometric features of the PPO. The 32 P Cherenkov counting efficiency (68.4%) obtained from this technique is 1.62 times as large as that measured with a conventional Cherenkov technique. (orig.)

  16. A catechol oxidase AcPPO from cherimoya (Annona cherimola Mill.) is localized to the Golgi apparatus.

    Cherimoya (Annona cherimola) is an exotic fruit with attractive organoleptic characteristics. However, it is highly perishable and susceptible to postharvest browning. In fresh fruit, browning is primarily caused by the polyphenol oxidase (PPO) enzyme catalyzing the oxidation of o-diphenols to quinones, which polymerize to form brown melanin pigment. There is no consensus in the literature regarding a specific role of PPO, and its subcellular localization in different plant species is mainly described within plastids. The present work determined the subcellular localization of a PPO protein from cherimoya (AcPPO). The obtained results revealed that the AcPPO- green fluorescent protein co-localized with a Golgi apparatus marker, and AcPPO activity was present in Golgi apparatus-enriched fractions. Likewise, transient expression assays revealed that AcPPO remained active in Golgi apparatus-enriched fractions obtained from tobacco leaves. These results suggest a putative function of AcPPO in the Golgi apparatus of cherimoya, providing new perspectives on PPO functionality in the secretory pathway, its effects on cherimoya physiology, and the evolution of this enzyme.

  18. Will the Amaranthus tuberculatus Resistance Mechanism to PPO-Inhibiting Herbicides Evolve in Other Amaranthus Species?

    Directory of Open Access Journals (Sweden)

    Chance W. Riggins

    2012-01-01

    Full Text Available Resistance to herbicides that inhibit protoporphyrinogen oxidase (PPO has been slow to evolve and, to date, is confirmed for only four weed species. Two of these species are members of the genus Amaranthus L. Previous research has demonstrated that PPO-inhibitor resistance in A. tuberculatus (Moq. Sauer, the first weed to have evolved this type of resistance, involves a unique codon deletion in the PPX2 gene. Our hypothesis is that A. tuberculatus may have been predisposed to evolving this resistance mechanism due to the presence of a repetitive motif at the mutation site and that lack of this motif in other amaranth species is why PPO-inhibitor resistance has not become more common despite strong herbicide selection pressure. Here we investigate inter- and intraspecific variability of the PPX2 gene—specifically exon 9, which includes the mutation site—in ten amaranth species via sequencing and a PCR-RFLP assay. Few polymorphisms were observed in this region of the gene, and intraspecific variation was observed only in A. quitensis. However, sequencing revealed two distinct repeat patterns encompassing the mutation site. Most notably, A. palmeri S. Watson possesses the same repetitive motif found in A. tuberculatus. We thus predict that A. palmeri will evolve resistance to PPO inhibitors via the same PPX2 codon deletion that evolved in A. tuberculatus.

    2015-01-01

    Polymer-based scintillator composites have been produced by combining polystyrene (PS) and Gd 2 O 3 :Eu 3+ scintillator nanoparticles. Polystyrene has been used since it is a flexible and stable binder matrix, resistant to thermal and light deterioration and with suitable optical properties. Gd 2 O 3 :Eu 3+ has been selected as scintillator material due to its wide band gap, high density and visible light yield. The optical, thermal and electrical characteristics of the composites were studied as a function of filler content, together with their performance as scintillator material. Additionally 1 wt.% of 2,5-diphenyloxazole (PPO) and 0.01 wt.% of 1,4 di[2-(5phenyloxazolyl)]benzene (POPOP) were introduced in the polymer matrix in order to strongly improve light yield, i.e., the measured intensity of the output visible radiation, under X-ray irradiation. Increasing scintillator filler concentration (from 0.25 to 7.5 wt.%) increases scintillator light yield and decreases the optical transparency of the composite. The addition of PPO and POPOP strongly increased the overall transduction performance of the composite due to specific absorption and re-emission processes. It is thus shown that Gd 2 O 3 :Eu 3+ /PPO/POPOP/PS composites with 0.25 wt.% of scintillator content with fluorescence molecules are suitable for the development of innovative large-area X-ray radiation detectors with huge demand from the industries.

    In plants and mammals, oxylipins may be synthesized via multi step processes that consist of dioxygenation and isomerization of the intermediately formed hydroperoxy fatty acid. These processes are typically catalyzed by two distinct enzyme classes: dioxygenases and cytochrome P450 enzymes. In ascomycetes biosynthesis of oxylipins may proceed by a similar two-step pathway. An important difference, however, is that both enzymatic activities may be combined in a single bifunctional enzyme. These types of enzymes are named Psi-factor producing oxygenases (Ppo). Here, the spatial organization of the two domains of PpoA from Aspergillus nidulans was analyzed by small-angle X-ray scattering and the obtained data show that the enzyme exhibits a relatively flat trimeric shape. Atomic structures of the single domains were obtained by template-based structure prediction and docked into the enzyme envelope of the low resolution structure obtained by SAXS. EPR-based distance measurements between the tyrosyl radicals formed in the activated dioxygenase domain of the enzyme supported the trimeric structure obtained from SAXS and the previous assignment of Tyr374 as radical-site in PpoA. Furthermore, two phenylalanine residues in the cytochrome P450 domain were shown to modulate the specificity of hydroperoxy fatty acid rearrangement. Copyright © 2013 Elsevier B.V.

    2002-01-01

    Full Text Available Cocoa flavour is greatly influenced by polyphenols. These compounds undergo a series of transformations during cocoa processing leading to the characteristic cocoa flavour. The use of exogenous polyphenol oxidase (PPO proved to be useful to reduce polyphenol content in cocoa nibs. The effect of a PPO associated or not with air over total phenol and tannin content was evaluated. Cocoa nibs were autoclaved and treated with a PPO or water in the absence or presence of an air flow for 0.5, 1, 2 and 3 hours. Total phenol content was reduced in PPO or water treatments, but when associated with air there was an increase in phenol content. Tannin content was reduced only by the treatment with water and air.

  10. N+ion-target interactions in PPO polymer: A structural characterization

    International Nuclear Information System (INIS)

    Das, A.; Dhara, S.; Patnaik, A.

    1999-01-01

    N + ion beam induced effects on the spin coated amorphous poly(2,6-dimethyl phenylene oxide) (PPO) films in terms of chemical structure and electronic and vibrational properties were investigated using Fourier Transform Infrared spectroscopy (FTIR) and Ultraviolet-Visible (UV-VIS) spectroscopy. Both techniques revealed that the stability of PPO was very weak towards 100 keV N + ions revealing the threshold fluence to be 10 14 ions/cm 2 for fragmentation of the polymer. FTIR analysis showed disappearance of all characteristic IR bands at a total fluence of 10 14 ions/cm 2 except for the band C=C at 1608 cm -1 which was found to shift to a lower wave number along with an enhancement in the full width half maximum (FWHM) value with increasing fluence. A new bond appeared due to oxidation as a shoulder at 1680 cm -1 in FTIR spectra indicating the presence of C=O type bond as a result of N + implantation on PPO films. The optical band gap (E g ) deduced from absorption spectra, was observed to decrease from 4.4 to 0.5 eV with fluence. The implantation induced carbonaceous clusters, determined using Robertson's formula for the optical band gap, were found to consist of ∼160 fused hexagonal aromatic rings at the maximum energy fluence. An enhanced absorption coefficient as a function of fluence indicated incorporation of either much larger concentration of charge carriers or their mobility than that of the pristine sample. Calculated band tail width from Urbach band tail region for the implanted samples pointed the band edge sharpness to be strongly dependent on fluence indicating an increased disorder with increasing fluence

    The Preferred Provider Organization concept is quickly becoming more popular because of its relative cost-effectiveness and recent successes. Managed care through means of this mental health and substance abuse PPO may well serve as the prototype for the general health care cost containment efforts of the future for the self-insured insurance plans for Alabama state employees and teachers. The first year also revealed several problems in the original proposal especially with respect to the unintended attractiveness of inpatient/residential care. Consequently, copayment plans were added to dissuade unnecessary lengthy stays (see Table 2). Second, a new quality assurance mechanism has been added to further evaluate the need for admissions to facilities, as well as for the need for continued inpatient treatment. The Alabama Quality Assurance Foundation (AQAF) began on January 1, 1988, conducting the preadmission certification on all admissions based upon criteria established jointly by AQAF and the PPO providers. In addition, AQAF will conduct continuing stay reviews at predetermined time periods to ensure that continued treatment in an inpatient setting is indeed necessary.

  17. Characterization of Plasmid pPO1 from the Hyperacidophile Picrophilus oshimae

    Full Text Available Picrophilus oshimae and Picrophilus torridus are free-living, moderately thermophilic and acidophilic organisms from the lineage of Euryarchaeota. With a pH optimum of growth at pH 0.7 and the ability to even withstand molar concentrations of sulphuric acid, these organisms represent the most extreme acidophiles known. So far, nothing is known about plasmid biology in these hyperacidophiles. Also, there are no genetic tools available for this genus. We have mobilized the 7.6 Kbp plasmid from P. oshimae in E. coli by introducing origin-containing transposons and described the plasmid in terms of its nucleotide sequence, copy number in the native host, mode of replication, and transcriptional start sites of the encoded ORFs. Plasmid pPO1 may encode a restriction/modification system in addition to its replication functions. The information gained from the pPO1 plasmid may prove useful in developing a cloning system for this group of extreme acidophiles.

  20. Boundary Lubrication of PEO-PPO-PEO Triblock Copolymer Physisorbed on Polypropylene, Polyethylene, and Cellulose Surfaces

    KAUST Repository

    Li, Yangyang

    2012-02-22

    In situ lateral force microscopy (LFM) and X-ray photoelectron spectroscopy (XPS) were used to probe the lubrication behavior of an aqueous solution of poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) (PEO-PPO-PEO) symmetric triblock copolymer on thin films of polypropylene (PP), polyethylene (PE), and cellulose. LFM experiments were carried out while the substrates were immersed in water and in solutions of the copolymer. The friction coefficient on PP and PE was reduced after adsorption from the PEO-PPO-PEO aqueous solution while the opposite effect was observed for cellulose surfaces. A critical normal loading force, at which the friction coefficient of the lubricated and unlubricated surfaces is equal, was identified and related to the affinity of the polymer with the substrate. Further experiments were performed to mimic practical operations involving lubricant addition during manufacturing and postprocessing removal. XPS was used to verify the presence of the lubricant on the polymeric substrates and to evaluate its removal by water washing. The lubricant layer was easily removed by water from the PP and cellulose surfaces while a durable layer was found on PE. The XPS results were in agreement with the highest critical normal loading force measured for PE (52 nN for PE in contrast to a minimum of 10 nN for cellulose). While several reports exist on lubrication on hard surfaces, friction behavior on soft surfaces is still not well documented as the substrates usually deform under loading pressure. Therefore, we also propose a simple lubrication model for PP, PE, and cellulose and the use of critical normal loading force as a parameter to predict lubricity and durability of adsorbed nonionic block copolymers. © 2012 American Chemical Society.

    The polyphenol oxidase (PPO) enzyme, which can catalyze the oxidation of phenolics to quinones, has been reported to be involved in undesirable browning in many plant foods. This phenomenon is particularly severe in artichoke heads wounded during the manufacturing process. A full-length cDNA encoding for a putative polyphenol oxidase (designated as CsPPO) along with a 1432 bp sequence upstream of the starting ATG codon was characterized for the first time from [Cynara cardunculus var. scolymus (L.) Fiori]. The 1764 bp CsPPO sequence encodes a putative protein of 587 amino acids with a calculated molecular mass of 65,327 Da and an isoelectric point of 5.50. Analysis of the promoter region revealed the presence of cis-acting elements, some of which are putatively involved in the response to light and wounds. Expression analysis of the gene in wounded capitula indicated that CsPPO was significantly induced after 48 h, even though the browning process had started earlier. This suggests that the early browning event observed in artichoke heads was not directly related to de novo mRNA synthesis. Finally, we provide the complete gene sequence encoding for polyphenol oxidase and the upstream regulative region in artichoke. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    The formation of water/oil emulsions can cause problems in various stages of production, processing and refining of petroleum. In this study, the technique of Fourier transform infrared spectroscopy (FTIR) using the method of attenuated total reflectance (ATR) was applied to study the solid-solutions of block copolymers based on poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) interface and its interaction in this interface with asphaltenic fractions of petroleum. The solid is the crystal of the ATR. Initially, we determined the critical micelle concentration values of the copolymers, which were consistent those obtained by a tensiometer. Bottle Test was also performed to correlate the efficiency of PEO-PPO copolymers in the breaking of water/oil emulsions with its adsorption at the interfaces solutions. (author)

    Full text: In this work we evaluated the viability of the tri-ureasil PPO hybrid as biofilm forming for release of active substances such as lignans. The samples were characterized by X-ray diffraction (XRD) and infrared (FTIR). The swelling degree and the influence of the catalyst on time of formation of a hybrid biofilm were evaluated. The cytotoxicity of the materials were evaluated using the XTT colorimetric assay where GM07492A strain was treated with different concentrations of the hybrid. The time of film formation depends on the quantity of the catalyst used in the synthesis. By varying the catalyst quantity during the synthesis, a good flexible film can be obtained, which is easy to be coated on the skin surface and in situ formed a very thin and comfortable film with an aesthetical appearance. Moreover, the hybrid films were colorless and transparent. The toxicity/viability of all samples has also been studied using normal human cells for future applications. The hybrid matrices did not significantly reduce cell viability, demonstrating that siloxane-polyether materials were biocompatible. All the materials presenting a amorphous structure (XRD) and the characteristic bands of vibrations (FTIR) of the polymer chain do not change after incorporation of lignans. (author)

    Poly ((ethylene oxide)-b-(propylene oxide)-b-(ethylene oxide)) triblock copolymers commonly known as poloxamers or Pluronics constitute an important class of nonionic, biocompatible surfactants. Here, a method is reported to incorporate two acid-labile acetal moieties in the backbone of poloxamers to generate acid-cleavable nonionic surfactants. Poly(propylene oxide) is functionalized by means of an acetate-protected vinyl ether to introduce acetal units. Three cleavable PEO-PPO-PEO triblock copolymers (Mn,total = 6600, 8000, 9150 g·mol(-1) ; Mn,PEO = 2200, 3600, 4750 g·mol(-1) ) have been synthesized using anionic ring-opening polymerization. The amphiphilic copolymers exhibit narrow molecular weight distributions (Ð = 1.06-1.08). Surface tension measurements reveal surface-active behavior in aqueous solution comparable to established noncleavable poloxamers. Complete hydrolysis of the labile junctions after acidic treatment is verified by size exclusion chromatography. The block copolymers have been employed as surfactants in a miniemulsion polymerization to generate polystyrene (PS) nanoparticles with mean diameters of ≈200 nm and narrow size distribution, as determined by dynamic light scattering and scanning electron microscopy. Acid-triggered precipitation facilitates removal of surfactant fragments from the nanoparticles, which simplifies purification and enables nanoparticle precipitation "on demand." © 2016 WILEY-VCH Verlag GmbH & Co.

    The production of pigments as secondary metabolites by microbes is known to vary by species and by physiological conditions within a single strain. The fungus strain Penicillium purpurogenum IAM15392 has been found to produce violet pigment (PP-V) and orange pigment (PP-O),Monascus azaphilone pigment homologues, when grown under specific culture conditions. In this study, we analysed PP-V and PP-O production capability in seven strains of P. purpurogenum in addition to strain IAM15392 under specific culture conditions. The pigment production pattern of five strains cultivated in PP-V production medium was similar to that of strain IAM15392, and all violet pigments produced by these five strains were confirmed to be PP-V. Strains that did not produce pigment were also identified. In addition, two strains cultivated in PP-O production medium produced a violet pigment identified as PP-V. The ribosomal DNA (rDNA) internal transcribed spacer (ITS) region sequences from the eight P. purpurogenum strains were sequenced and used to construct a neighbor-joining phylogenetic tree. PP-O and PP-V production of P. purpurogenum was shown to be related to phylogenetic placement based on rDNA ITS sequence. Based on these results, two hypotheses for the alteration of pigment production of P. purpurogenum in evolution were proposed. Copyright © 2015 The British Mycological Society.

  8. The effects of PPO activity on the proteome of ingested red clover and implications for improving the nutrition of grazing cattle.

    Increasing the rumen-stable protein content of feed would lead to improved nitrogen utilisation in cattle, and less nitrogenous waste. Red clover (Trifolium pratense L.) is a high protein ruminant feed containing high polyphenol oxidase (PPO) activity. PPO mediated protein-quinone binding has been linked to protecting plant proteins from proteolysis. To explore the mechanism underlying the effect of PPO on protein protection in fresh forage feeds, proteomic components of feed down-boli produced from wild-type red clover and a low PPO mutant, at point of ingestion and after 4h in vitro incubation with rumen inoculum were analysed. Significant differences in proteomic profiles between wild-type and mutant red clover were determined after 4h incubation, with over 50% less spots in mutant than wild-type proteomes, indicating decreased proteolysis in the latter. Protein identifications revealed preferentially retained proteins localised within the chloroplast, suggesting that PPO mediated protection in the wild-type operates due to the proximity of target proteins to the enzyme and substrates, either diffusing into this compartment from the vacuole or are present in the chloroplast. This increased understanding of protein targets of PPO indicates that wider exploitation of the trait could contribute to increased protein use efficiency in grazing cattle. One of the main challenges for sustainable livestock farming is improving capture of dietary nitrogen by ruminants. Typically up to 70% of ingested protein-N is excreted representing a loss of productivity potential and a serious environmental problem in terms of nitrogenous pollution of lands and water. Identification of key characteristics of rumen-protected protein will deliver target traits for selection in forage breeding programmes. The chloroplastic enzyme PPO catalyzes the oxidation of phenols to quinones, which react with protein. Little is currently known about the intracellular protein targets of the products

  9. Modeling the Phase Behavior of PEO-PPO-PEO Surfactants in Carbon Dioxide Using the PC-SAFT Equation of State: Application to Dry Decontamination of Solid Substrates

    The phase behavior of several commercially available poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) block copolymers (PEO-PPO-PEO or Pluronics L) in compressed carbon dioxide has been investigated within the framework of dry nuclear decontamination. For this purpose, cloud points have been measured in the pressure and temperature range from P = (10 to 40) MPa and from T = (293 to 338) K, respectively. To find a reliable method for surfactant selection, the perturbed-chain statistical association fluid theory (PC-SAFT) equation of state (EoS) has been applied to model the experimental data. The pure-component and the respective homopolymer + CO 2 binary interaction parameters have been fitted to liquid densities and to homopolymer + CO 2 binary equilibrium data. The phase behavior of Pluronics L copolymers as a function of concentration, molar mass, and copolymer composition has been predicted very accurately using a constant PEO-PPO binary interaction parameter k(PEO-PPO) = 0.007. The P and SAFT model was also successfully applied to Pluronics R copolymers (PPO-PEO-PPO), although a different k(PEO-PPO) = -0.018 was required to match the experimental data. The model predictions have shown that Pluronics L copolymers with molar mass M ≤ 2750 g.mol -1 and a PEO mass fraction in the copolymer of less than 30 % have sufficiently low cloud-point pressures and are therefore the most suitable for the decontamination process.

  11. The Effect of Surfactant and Compatibilizer on Inorganic Loading and Properties of PPO-based EPMM Membranes

    Science.gov (United States)

    Bissadi, Golnaz

    Hybrid membranes represent a promising alternative to the limitations of organic and inorganic materials for high productivity and selectivity gas separation membranes. In this study, the previously developed concept of emulsion-polymerized mixed matrix (EPMM) membranes was further advanced by investigating the effects of surfactant and compatibilizer on inorganic loading in poly(2,6-dimethyl-1,4-phenylene oxide) (PPO)-based EPMM membranes, in which inorganic part of the membranes originated from tetraethylorthosilicate (TEOS). The polymerization of TEOS, which consists of hydrolysis of TEOS and condensation of the hydrolyzed TEOS, was carried out as (i) one- and (ii) two-step processes. In the one-step process, the hydrolysis and condensation take place in the same environment of a weak acid provided by the aqueous solution of aluminum hydroxonitrate and sodium carbonate. In the two-step process, the hydrolysis takes place in the environment of a strong acid (solution of hydrochloric acid), whereas the condensation takes place in weak base environment obtained by adding excess of the ammonium hydroxide solution to the acidic solution of the hydrolyzed TEOS. For both one- and two-step processes, the emulsion polymerization of TEOS was carried out in two types of emulsions made of (i) pure trichloroethylene (TCE) solvent, and (ii) 10 w/v% solution of PPO in TCE, using different combinations of the compatibilizer (ethanol) and the surfactant (n-octanol). The experiments with pure TCE, which are referred to as a gravimetric powder method (GPM) allowed assessing the effect of different experimental parameters on the conversion of TEOS. The GPM tests also provided a guide for the synthesis of casting emulsions containing PPO, from which the EPMM membranes were prepared using a spin coating technique. The synthesized EPMM membranes were characterized using 29Si nuclear magnetic resonance (29Si NMR), differential scanning calorimetry (DSC), inductively coupled plasma mass

    The Premiere-Chute hydroelectric power station, commissioned in 1968, has four hydraulic turbines for a total of 130 MW. One of the pilasters of the dam weir, built with pre-stressed concrete, showed a crack at the level of the post-tension cable. This paper presented an evaluation of the behaviour of the pilaster in question, No. 9. The main goal was to prevent any disruption to the gate opening through adequate monitoring for a long term data follow-up. Six long-base OSMOS type optical sensors were installed on each face of the spillway pilaster. The behaviour of the No. 9 pilaster was then compared with that of other pilasters with respect to the effects of temperature and water level fluctuation in the dam. After the pilasters had been monitored for six months, it was found that No. 9 pilaster showed the least deformation of all. It was therefore concluded that the behaviour of this pilaster was normal.

    In this case, the Au-F127 (triblock copolymer PEO 106 PPO 70 PEO 106 , PEO is short for polyethylene oxide and PPO is the abbreviation of polypropene oxide) hybrid hairy nanospheres were obtained by the redox reaction using pluronic F127 and HAuCl 4 as precursor. A novel hemoglobin (Hb) biosensor was fabricated by immobilizing the Hb onto the Au-F127 film on the surface of glassy carbon electrode (GCE). The Au-F127 nanocomposites and Hb were characterized by transmission electron microscopy (TEM), polycrystalline electron diffraction ring pattern and ultra-violet visible spectra (UV–vis). UV–vis spectra suggested that Hb in the film could keep its native secondary structure. The performances of Hb/(Au-F127) on GCE were characterized with cyclic voltammetry (CV) and typical amperometric response (i–t) measurements. The immobilized Hb maintained its bioactivity and displayed an excellent electrochemical behavior with a formal potential of −339 mV. The resulting electrode showed an electrocatalytic activity to hydrogen peroxide (H 2 O 2 ). The linear response range of the H 2 O 2 biosensor was from 3.0 × 10 −7 to 5.7 × 10 −4 M with a low detection limit of 4.0 × 10 −8 M.

    2016-07-01

    Full Text Available Numerous functionalization methods have been employed to increase the solubility, and therefore, the processability of fullerenes in composite structures, and of these radical addition reactions continue to be an important methodology. C60 and Sc3N@C80 derivatives were prepared via radical addition of the photodecomposition products from the commercial photoinitiator TMB-PPO, yielding C60(TMB-PPO5 and Sc3N@C80(TMB-PPO3 as preferred soluble derivatives obtained in high yields. Characterization of the mixture of isomers using standard techniques suggests an overall 1PPO:6TMB ratio of addends, reflecting the increased reactivity of the carbon radical. Although, a higher percentage of PPO is observed in the Sc3N@C80(TMB-PPO3 population, perhaps due to reverse electronic requirements of the substrate. Visually dispersed thiol-ene nanocomposites with low extractables were prepared using two monomer compositions (PETMP:TTT and TMPMP:TMPDE with increasing fullerene derivative loading to probe network structure-property relationships. Thermal stability of the derivatives and the resulting networks decreased with increased functionality and at high fullerene loadings, respectively. TMPMP:TMPDE composite networks show well-dispersed derivatives via TEM imaging, and increasing Tg’s with fullerene loading, as expected for the incorporation of a more rigid network component. PETMP:TTT composites show phase separation in TEM, which is supported by the observed Tg’s. Singlet oxygen generation of the derivatives decreases with increased functionality; however, this is compensated for by the tremendous increase in solubility in organic solvents and miscibility with monomers. Most importantly, singlet oxygen generation from the composites increased with fullerene derivative loading, with good photostability of the networks.

    New composite scintillation detectors were obtained by incorporation of PPO and o-POPOP organic scintillators into porous sol–gel silica matrices. Composites possess high photoluminescence intensity and decay time in nanosecond range. The absolute light yield of composite scintillators at excitation by alpha-radiation is about 4000–5000 photons/MeV and the pulse–height resolution is about 30%. The investigations of time-resolved luminescence of composites performed under excitation by synchrotron radiation in the 3.7–25 eV range have shown that the non-radiative energy transfer between host matrix and dopant molecules occurs via singlet states of SiO{sub 2} oxygen-deficient centers.

  17. Permeability and Selectivity of PPO/Graphene Composites as Mixed Matrix Membranes for CO2 Capture and Gas Separation

    Directory of Open Access Journals (Sweden)

    Riccardo Rea

    2018-01-01

    Full Text Available We fabricated novel composite (mixed matrix membranes based on a permeable glassy polymer, Poly(2,6-dimethyl-1,4-phenylene oxide (PPO, and variable loadings of few-layer graphene, to test their potential in gas separation and CO2 capture applications. The permeability, selectivity and diffusivity of different gases as a function of graphene loading, from 0.3 to 15 wt %, was measured at 35 and 65 °C. Samples with small loadings of graphene show a higher permeability and He/CO2 selectivity than pure PPO, due to a favorable effect of the nanofillers on the polymer morphology. Higher amounts of graphene lower the permeability of the polymer, due to the prevailing effect of increased tortuosity of the gas molecules in the membrane. Graphene also allows dramatically reducing the increase of permeability with temperature, acting as a “stabilizer” for the polymer matrix. Such effect reduces the temperature-induced loss of size-selectivity for He/N2 and CO2/N2, and enhances the temperature-induced increase of selectivity for He/CO2. The study confirms that, as observed in the case of other graphene-based mixed matrix glassy membranes, the optimal concentration of graphene in the polymer is below 1 wt %. Below such threshold, the morphology of the nanoscopic filler added in solution affects positively the glassy chains packing, enhancing permeability and selectivity, and improving the selectivity of the membrane at increasing temperatures. These results suggest that small additions of graphene to polymers can enhance their permselectivity and stabilize their properties.

    A series of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO)-based organic-inorganic hybrid materials for anion exchange were prepared through sol-gel process of polymer precursors PPO-Si(OCH 3 ) 3 . PPO-Si(OCH 3 ) 3 were obtained from the reaction of bromomethylated PPO with 3-aminopropyl-trimethoxysilane (A1110). These polymer precursors then underwent hydrolysis and condensation with additional A1110 to generate hybrid materials. The reaction to produce polymer precursors was identified by FTIR; while FTIR, TGA, XRD, SEM, as well as conventional ion exchange capacity (IEC) measurements were conducted for the structures and properties of the prepared hybrids. TGA results show that this series of hybrid materials possess high thermal stability; XRD and SEM indicate that the prepared hybrid materials are amorphous and the inorganic and organic contents show good compatibility if the ratio between them is proper. The IEC values of the hybrid materials due to the amine groups range from 1.13 mmol/gBPPO (material i) to 4.80 mmol/gBPPO (material iv)

    1998-12-01

    NASA's Advanced X-ray Astrophysics Facility has been renamed the Chandra X-ray Observatory in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar. The telescope is scheduled to be launched no earlier than April 8, 1999 aboard the Space Shuttle Columbia mission STS-93, commanded by astronaut Eileen Collins. Chandrasekhar, known to the world as Chandra, which means "moon" or "luminous" in Sanskrit, was a popular entry in a recent NASA contest to name the spacecraft. The contest drew more than six thousand entries from fifty states and sixty-one countries. The co-winners were a tenth grade student in Laclede, Idaho, and a high school teacher in Camarillo, CA. The Chandra X-ray Observatory Center (CXC), operated by the Smithsonian Astrophysical Observatory, will control science and flight operations of the Chandra X-ray Observatory for NASA from Cambridge, Mass. "Chandra is a highly appropriate name," said Harvey Tananbaum, Director of the CXC. "Throughout his life Chandra worked tirelessly and with great precision to further our understanding of the universe. These same qualities characterize the many individuals who have devoted much of their careers to building this premier X-ray observatory." "Chandra probably thought longer and deeper about our universe than anyone since Einstein," said Martin Rees, Great Britain's Astronomer Royal. "Chandrasekhar made fundamental contributions to the theory of black holes and other phenomena that the Chandra X-ray Observatory will study. His life and work exemplify the excellence that we can hope to achieve with this great observatory," said NASA Administrator Dan Goldin. Widely regarded as one of the foremost astrophysicists of the 20th century, Chandrasekhar won the Nobel Prize in 1983 for his theoretical studies of physical processes important to the structure and evolution of stars. He and his wife immigrated from India to the U.S. in 1935. Chandrasekhar served on the faculty of the University of

    The ages of seven individual clinopyroxene inclusions in Premier diamonds of eclogitic association have been determined using the 40 Ar- 39 Ar dating technique. Syngenetic inclusions weighing between 10 and 130 μg were exposed on cleaved surfaces of the diamonds and analysed using a laser probe. The inclusion ages were found to be in the range 1111±35 to 1254±38 Ma with an average of 1185±94 Ma. The ages obtained are in good agreement with previous determinations made on aggregates of eclogitic inclusions from Premier diamonds and demonstrate the applicability of the laser probe to dating individual diamond inclusions.

    Pay for performance has become a central strategy in the drive to improve health care. We assessed the long-term effect of the Medicare Premier Hospital Quality Incentive Demonstration (HQID) on patient outcomes. We used Medicare data to compare outcomes between the 252 hospitals participating in the Premier HQID and 3363 control hospitals participating in public reporting alone. We examined 30-day mortality among more than 6 million patients who had acute myocardial infarction, congestive heart failure, or pneumonia or who underwent coronary-artery bypass grafting (CABG) between 2003 and 2009. At baseline, the composite 30-day mortality was similar for Premier and non-Premier hospitals (12.33% and 12.40%, respectively; difference, -0.07 percentage points; 95% confidence interval [CI], -0.40 to 0.26). The rates of decline in mortality per quarter at the two types of hospitals were also similar (0.04% and 0.04%, respectively; difference, -0.01 percentage points; 95% CI, -0.02 to 0.01), and mortality remained similar after 6 years under the pay-for-performance system (11.82% for Premier hospitals and 11.74% for non-Premier hospitals; difference, 0.08 percentage points; 95% CI, -0.30 to 0.46). We found that the effects of pay for performance on mortality did not differ significantly among conditions for which outcomes were explicitly linked to incentives (acute myocardial infarction and CABG) and among conditions not linked to incentives (congestive heart failure and pneumonia) (P=0.36 for interaction). Among hospitals that were poor performers at baseline, mortality was similar in the two groups of hospitals at the start of the study (15.12% and 14.73%; difference, 0.39 percentage points; 95% CI, -0.36 to 1.15), with similar rates of improvement per quarter (0.10% and 0.07%; difference, -0.03 percentage points; 95% CI, -0.08 to 0.02) and similar mortality rates at the end of the study (13.37% and 13.21%; difference, 0.15 percentage points; 95% CI, -0.70 to 1.01).

    Elaboration of mesostructured silica films with a triblock copolymer polyethylene oxide-polypropylene oxide-polyethylene oxide, (PEO-PPO-PEO) and controlled growth of silver nanoparticles in the mesostructure are described. The films are characterized using UV-visible optical absorption spectroscopy, TEM, AFM, SEM, X-ray diffraction (XRD) and Rutherford backscattering spectrometry (RBS). Organized arrays of spherical silver nanoparticles with diameter between 5 and 8 nm have been obtained by NaBH 4 reduction. The size and the repartition of silver nanoparticles are controlled by the film mesostructure. The localization of silver nanoparticles exclusively in the upper-side part of the silica-block copolymer film is evidenced by RBS experiment. On the other hand, by using a thermal method, 40 nm long silver sticks can be obtained, by diffusion and coalescence of spherical particles in the silica-block copolymer layer. In this case, migration of silver particles toward the glass substrate-film interface is shown by the RBS experiment. - Graphical abstract: Growth of silver nanoparticles in a mesostructured block copolymer F127-silica film is performed either by a chemical route involving NaBH 4 reduction or by a thermal method. An array of spherical silver nanoparticles with 10 nm diameter on the upper-side of the mesostructured film or silver sticks long of 40 nm with a preferential orientation are obtained according to the method used. a: TEM image of the Fag5SiNB sample illustrating the silver nanoparticles array obtained by the chemical process; b: HR-TEM image of the Fag20Sid2 sample illustrating the silver nanosticks obtained by the thermal process.

  14. 40Ar/39Ar laser-probe dating of diamond inclusions from the Premier kimberlite

    Phillips, D.; Onstott, T.C.; Harris, J.W.; Strathclyde Univ., Glasgow

    1989-01-01

    Inclusions encapsulated by diamonds at the time of their formation provide a means for determining diamond crystallization ages and the chemistry of the surrounding upper mantle at that time. Sm-Nd studies of peridotitic inclusions, from Cretaceous-age kimberlites in southern Africa, suggest that the diamonds formed 3.3 Gyr ago. By contrast, eclogite-suite inclusions generally yield younger ages, sometimes approaching the time of kimberlite eruption. Here we report the results of 40 Ar/ 39 Ar laser-probe analyses of individual eclogitic clinopyroxene inclusions from Premier diamonds, which yield a mean age of 1,198±14 Myr. This age agrees well with Sm-Nd and 40 Ar/ 39 Ar analyses on similar Premier inclusions, and is indistinguishable from the inferred time of emplacement of the host kimberlite (1,150-1,230 Myr), which implies that diamond formation was essentially synchronous with kimberlite generation. The extrapolated non-radiogenic 40 Ar/ 36 Ar ratio of 334±102 is similar to the present-day atmospheric composition. This value is inconsistent with Sr and Nd isotopic signatures from Premier eclogite inclusions, which suggest a depleted mantle source ( 40 Ar/ 36 Ar>20,000). Pre-entrapment equilibration of the inclusions with an 36 Ar-rich fluid is the most probable explanation for the low non-radiogenic ( 40 Ar/ 36 Ar) composition. (author)

    The organization of Tetronic 908 registered (T908), a star copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) blocks, has been examined. Above critical conditions of temperature and concentration, the micelles formed by the aggregation of PPO units self-organize into particular structures. While small-angle neutron scattering (SANS) characterizations performed with static conditions demonstrate the organization of the medium, the experimental results do not allow us to make a distinction between simple cubic and body-centered-cubic structures. However, SANS measurements realized under shear produce characteristic diffraction diagrams. In this paper, an accurate methodology is proposed to identify, without ambiguity, the exact nature of the organized phase. Applied to our system, indexing of the diffraction pattern spots reveals that the organization of T908 is of bcc type oriented with the [111] direction parallel to the direction of flow, but the crystals can present any orientation about this direction. The lattice size has been estimated and compared to previous published results

    Foxtail millet shows variation in positive phenol color reaction (Phr) and negative Phr in grains, but predominant accessions of this crop are negative reaction type, and the molecular genetic basis of the Phr reaction remains unresolved. In this article, we isolated polyphenol oxidase (PPO) gene responsible for Phr using genome sequence information and investigated molecular genetic basis of negative Phr and crop evolution of foxtail millet. First of all, we searched for PPO gene homologs in a foxtail millet genome database using a rice PPO gene as a query and successfully found three copies of the PPO gene. One of the PPO gene homologs on chromosome 7 showed the highest similarity with PPO genes expressed in hulls (grains) of other cereal species including rice, wheat, and barley and was designated as Si7PPO. Phr phenotypes and Si7PPO genotypes completely co-segregated in a segregating population. We also analyzed the genetic variation conferring negative Phr reaction. Of 480 accessions of the landraces investigated, 87 (18.1 %) showed positive Phr and 393 (81.9 %) showed negative Phr. In the 393 Phr negative accessions, three types of loss-of-function Si7PPO gene were predominant and independently found in various locations. One of them has an SNP in exon 1 resulting in a premature stop codon and was designated as stop codon type, another has an insertion of a transposon (Si7PPO-TE1) in intron 2 and was designated as TE1-insertion type, and the other has a 6-bp duplication in exon 3 resulting in the duplication of 2 amino acids and was designated as 6-bp duplication type. As a rare variant of the stop codon type, one accession additionally has an insertion of a transposon, Si7PPO-TE2, in intron 2 and was designated as "stop codon +TE2 insertion type". The geographical distribution of accessions with positive Phr and those with three major types of negative Phr was also investigated. Accessions with positive Phr were found in subtropical and tropical regions at

    Full Text Available Smart economy implies the development of key factors like global economy growth, competition, economic progress, economic prosperity, innovation. In the European top-level football, like the case of the British Premier League, financial indicators have demonstrated that the factors that define smart economy can be identified. The new rules of the financial fair-play policies and the ever growing revenues for television rights have created a new market in sports economy, one that identifies itself with the criteria identifies in studies regarding smart economy. This paper comparatively examines the determinants of four indicators of the football team quality in the British Premier League, in order to find out whether a common set of potential determinants could be effective in improving all four indicators of quality, without worsening any of them. This allows finding what measures undertaken at the level of football teams could raise the football team quality. Considering the subjective and multidimensional nature of the football team quality, we first propose four indicators that might be appropriate to define this latent summative measure. Then we select a number of four potentially common determinants of the football team quality, and finally discuss the empirical results, based on panel generalized least squares regression models. The television broadcasting rights are found to be the most important determinant of the football team quality.

    Hamstring injuries constitute one of the most concerning injuries in English Premier League football, due to its high primary incidence but also its recurrence. Functional methods assessing hamstring function during high-risk performance tasks such as sprinting are vital to identify potential risk factors. The purpose of this study was to assess horizontal force deficits during maximum sprint running on a non-motorized treadmill in football players with previous history of hamstring strains as a pre-season risk-assessment in a club setting. 17 male football players from one Premier League Club were divided into 2 groups, experimental (n=6, age=24.5±2.3 years) and control (n=11, age=21.3±1.2 years), according to history of previous hamstring injury. Participants performed a protocol including a 10-s maximum sprint on a non-motorized treadmill. Force deficits during acceleration phase and steady state phases of the sprint were assessed between limbs and between groups. The main outcome measures were horizontal and vertical peak forces during the acceleration phase or steady state. There were no significant differences in peak forces between previously injured and non-injured limbs, or between groups, challenging the ideas around functional force deficits in sprint running as a diagnostic measure of hamstring re-injury risk. © Georg Thieme Verlag KG Stuttgart · New York.

    Although there is growing awareness of the impact of diet on health, little attention has been given to the food available in our sports stadia. We used a football club (Citygrene FC) - Citygrene is a fictional name - in the English Premier League as a case study to examine the attitudes of male and female football supporters to the food and drink available at their home stadium (Citygrene Stadium). The research design used five focus groups of male and female fans. The discourse was audiotaped, transcribed, coded and analysed for themes. A football stadium in the English Premier League, England. The participants were season ticket holders drawn from two stands at Citygrene Stadium. The research showed a high level of dissatisfaction with the food and drink supplied. There were key differences in the views of the male and female participants in the focus groups, with the women more concerned about wider issues such as the lack of healthy food. Both men and women were aware of their role as consumers and felt that there was an opportunity for Citygrene to improve their catering profits, if they provided a better selection of food and drink and an improved service. The study shows that there is a demand for healthier food options (and a wider choice of food and drink in general), which may provide an economic opportunity for stadium and catering managers. In addition, a stadium may be considered a potential 'healthy setting', which can serve as a supportive environment for healthier food choices.

    The Premiers-Governors energy discussions are aimed at promoting joint energy cooperation between provinces and states. This report outlines the major accomplishments in the implementation of the Climate Change Action Plan adopted by the Conference in 1998. The project priorities for the coming year are also outlined. In 2001, the New England Governors (NEG) and the Eastern Canadian Premiers (ECP) directed the Environment Committee and the Northeast International Committee on Energy (NICE) to implement a plan to develop a regional emissions inventory so that participating jurisdictions would have common data for measuring progress. The plan also identified specific climate actions that could be readily implemented. This report describes the results of 5 working groups which were created to focus on the following potential categories: energy, transportation, inventory and registry, adaptation, and 'lead by example'. In addition to the working groups, the Climate Change Steering Committee developed 4 proposals for consideration for implementation. These were the LED Traffic Light Proposal, the College and University Partnerships in Emissions Reductions, State/Provincial Purchasing Programs for High Efficiency-Low Emission Office Equipment, and Use of Cleaner, More Energy-Efficient Vehicles in State/Provincial Fleets. The Steering Committee will also pursue other tasks in the coming year, including the study of other proposals for cost-effective measures that could contribute to the goals of the Climate Change Action Plan, examine Internet options for coordinating internal project work, examine opportunities to pursue climate action, and identify opportunities to improve vehicle fuel efficiency

    Single-crystal PbS nanorods were successfully synthesized through a simple hydrothermal route using PEO-PPO-PEO triblock copolymer (P123) as a structure-directing agent. The XRD pattern indicates that the crystal structure of the nanorods is face-centre-cubic rocksalt. A SEM image shows that the nanorods have a diameter of 40-70 nm and a length of 200-600 nm, and both tips exhibit taper-like structures. HRTEM and SAED images reveal the single-crystalline nature of the nanorods with the growth along the (111) direction. The experimental results indicated that the P123 concentration and reaction temperature played important roles in controlling the morphology of the PbS nanostructures. The optical property of PbS nanorods was investigated by UV-Vis absorption spectroscopy and the band structure was calculated by the B3LYP hybrid density functional theory.

    Full Text Available Les promenades maritimes caractérisent les stations de bord de mer du premier âge touristique (1850-1930. Elles traduisent dans le paysage un urbanisme spéculatif, à rapprocher de celui qui produit le square et le boulevard, et donnent lieu à une urbanisation du littoral sous forme de vastes appendices linéaires. Les pratiques sociales associées à la promenade rappellent celles du jardin de plaisir, et renvoient au même rêve d’une urbanité idéale, libérée des miasmes, des promiscuités sociales, des contraintes qui pèsent sur les amours et les jeux.

  6. What’s a Cricketer’s Worth? Predicting Bid Prices for Indian Premier League Auctions

    Full Text Available Indian Premier League is a twenty-over format cricket tournament of teams representing different Indian cities. Beginning 2008, it is established now as a grand annual affair. The team franchises are auctioned on long term basis, whereas cricketers are auctioned every season under certain conditions. Despite such wealth of information, studies on IPL auctions are rare barring four cited models. The present paper studies the results of year 2011 English-style auction of cricketers and recalibrates the old yet most accurate model by Rastogi and Deodhar (2009. Both models use ordinary least square method of regression albeit with different variable. The old models lack predictive power, whereas the recalibrated model presented displays better predictive capability as compared to earlier models. It also succeeds in reducing overall predictability gap and stands significantly parsimonious vis-à-vis previous models. Further, the final model presented is applied on 2013 and 2014 auction data to show superior results.

    Despite numerous studies which have been done regarding soccer injuries worldwide, there is lack of available data considering the epidemiology of injuries in the Iranian soccer premier league, although it is the most popular sport in the country. The main goal of this research was to determine the incidence of physical injuries in the studied population, considering other characteristics such as site, type and mechanism as well. Twenty one adult male professional soccer players (age 24±3), members of a team (Tehran-Pas) participating in Iranian premier league, were followed during a 4-month period. The injury characteristics and exposure times were recorded by the team physician during all the matches and training sessions. The total exposure time was 2610 playing hours (2352 h of training versus 258 h of competition). Eighty six percent of the injuries were acute. Incidence of acute injuries was 16.5 (95% CI: 12-22) per 1000 hours of playing (11.5 per 1000 hrs of training and 62 per 1000 hrs of competition). The most common types of injuries were strains followed by contusions, each of which constituted 30% of acute injuries. More than 80% of injuries occurred in lower limbs, especially in thigh and groin regions. Nearly 60% of acute injuries occurred in dominant side of the body, and collision was the reason of about half of the acute injuries. Severity of more than 70% of the injuries was minor. On average each injury had led the player being off the field for about 10 days. The incidence of injury in this research is in range of numbers obtained in important international tournaments but the rate of injuries during training sessions is higher than comparable studies.

    A hydrogel chitosan sorbent ionically cross-linked with sodium citrate and covalently cross-linked with epichlorohydrin was used to remove nutrients from an equimolar mixture of P-PO 4 , N-NO 2 and N-NO 3 . The scope of the study included, among other things, determination of the influence of pH on nutrient sorption effectiveness, nutrient sorption kinetics as well as determination of the maximum sorption capacity of cross-linked chitosan sorbents regarding P-PO 4 (H 2 PO 4 - , HPO 4 2- ), N-NO 2 (HNO 2 , NO 2 - ), and N-NO 3 (NO 3 - ). The effect of the type of the cross-linking agent on the affinity of the modified chitosan to each nutrient was studied as well. The kinetics of nutrient sorption on the tested chitosan sorbents was best described with the pseudo-second order model. The model of intramolecular diffusion showed that P-PO 4 , N-NO 2 and N-NO3 sorption on cross-linked hydrogel chitosan beads proceeded in two phases. The best sorbent of nutrients turned out to be chitosan cross-linked covalently with epichlorohydrin; with P-PO 4 , N-NO 2 and N-NO 3 sorption capacity reaching: 1.23, 0.94 and 0.76mmol/g, respectively (total of 2.92mmol/g). For comparison, the sorption capacity of chitosan cross-linked ionically with sodium citrate was: 0.43, 0.39 and 0.39mmol/g for P-PO 4 , N-NO 2 and N-NO 3 , respectively (total of 1.21mmol/g).

  15. Associated chemical and carbon isotopic composition variations in diamonds from Finsch and Premier kimberlite, South Africa

    International Nuclear Information System (INIS)

    Deines, P.

    1984-01-01

    The carbon isotopic composition of 66 inclusion-containing diamonds from the Premier kimberlite, South Africa, 93 inclusion-containing diamonds and four diamonds of two diamond-bearing peridotite xenoliths from the Finsch kimberlite, South Africa was measured. The data suggest a relationship between the carbon isotopic composition of the diamonds and the chemical composition of the associated silicates. For both kimberlites similar trends are noted for diamonds containing peridotite-suite inclusions (P-type) and for diamonds containing eclogite-suite inclusions (E-type): Higher delta 13 C P-type diamonds tend to have inclusions lower in SiO 2 , Al 2 O 3 , Cr 2 O 3 , MgO, Mg/(Mg + Fe) and higher in FeO and CaO. Higher delta 13 C E-type diamonds tend to have inclusions lower in SiO 2 , Al 2 O 3 , MgO, Mg/(Mg + Fe), Na 2 O, K 2 O, TiO 2 and higher in CaO, Ca/(Ca + Mg). Consideration of a number of different models that have been proposed for the genesis of kimberlites, their zenoliths and diamonds shows that they are all consistent with the conclusion that in the mantle, regions exist that are characterized by different mean carbon isotopic compositions.

    Various types of linear systems are described which are not affected by the first breakdown. They make it possible to operate continuously and are thus very reliable. This is because the first breakdown which occurs affects only very slightly the operation. These components can be replaced during working. The operation, the errors, and the detection are briefly considered in the case of three different designs of linear servo systems. An attempt at comparison is made, it could be developed in a particular case. (author) [French] On decrit divers types de systemes lineaires survivant a la premiere panne.

    Neutron-activation studies of the impurity chemistry of more than 1500 natural diamonds from three South African kimberlite sources, Premier, Finsch, and Jagersfontein, provide evidence for the presence of submicroscopic inclusions of a quenched (or temperature re-equilibrated) melt from which these diamonds crystallized. These microscopic inclusions of parental magma contain variable amounts of fluids rich in water and carbon dioxide, as well as iron-nickelcopper-cobalt sulphides, and a major silicate phase, which is remarkably constant in composition irrespective of the source of the diamonds and the age of emplacement of their host kimberlite. These microscopic inclusions are present in varying amounts in all the diamonds that were analysed, and may even dominate the impurity chemistry of diamonds having observable mineral inclusions. An estimate of the composition of the major elements in the silicate melt indicates that the diamonds that were investigated crystallized from picritic magma rich in water and carbon dioxide in the presence of immiscible iron-nickel-copper-cobalt sulphides [af

    Full Text Available This paper presents a contemporary literature review of design science research (DSR studies in the domain of decision support systems (DSS development. The latest studies in the DSS design domain claim that DSR methodologies are the most popular design approach, but many details are still yet to be revealed for supporting this claim. In particular, it is important to thoroughly investigate the trends in either the form or deeper insights in use of DSR in this field. The aim of this study is to analyse the existing DSS design science studies to reveal insights into the use of DSR, so that we can outline research agenda for a special issue, based on findings of analysis. We selected articles (from 2005 to 2014 that were published in seven selected premier IS journals (ranked as A* in the ABDC journal ranking. The selected 57 sample articles are representative of DSS design studies that used DSR in theorising, designing, implementing, and evaluating DSS solutions. We discuss the theoretical positions of DSR for DSS development through six categories: DSS artefacts, DSR methods, DSR views, user involvement, DSS design innovations and problem domains. The findings indicate that new studies are needed to fill the knowledge gap in DSS design science, for more solid theoretical basis in near future.

    To examine the behavioral processes through which lifestyle interventions impacted weight loss. The analyses were limited to overweight and obese Black and White adults randomized to a PREMIER lifestyle intervention (N = 501). Structural equation modeling was conducted to test the direct and indirect relationships of session attendance, days of self-monitoring diet and exercise, change in diet composition and exercise, and 6-month weight change. Greater session attendance was associated with increased self-monitoring, which was in turn significantly related to reduction in percent energy from total fat consumed. Change in percent energy from fat and self-monitoring was associated with 6-month percent change in weight. Both a decrease in fat intake and increase in self-monitoring are potential mediators of the relationship between attendance and weight change. The findings provide a reasonable model that suggests regular session attendance and use of behavioral strategies like self-monitoring are associated with improved behavioral outcomes that are associated with weight loss.

    The issues of modeling asscoiation football prediction model has become increasingly popular in the last few years and many different approaches of prediction models have been proposed with the point of evaluating the attributes that lead a football team to lose, draw or win the match. There are three types of approaches has been considered for predicting football matches results which include statistical approaches, machine learning approaches and Bayesian approaches. Lately, many studies regarding football prediction models has been produced using Bayesian approaches. This paper proposes a Bayesian Networks (BNs) to predict the results of football matches in term of home win (H), away win (A) and draw (D). The English Premier League (EPL) for three seasons of 2010-2011, 2011-2012 and 2012-2013 has been selected and reviewed. K-fold cross validation has been used for testing the accuracy of prediction model. The required information about the football data is sourced from a legitimate site at http://www.football-data.co.uk. BNs achieved predictive accuracy of 75.09% in average across three seasons. It is hoped that the results could be used as the benchmark output for future research in predicting football matches results.

    The daily distribution of macronutrient intake can modulate aspects of training adaptations, performance and recovery. We therefore assessed the daily distribution of macronutrient intake (as assessed using food diaries supported by the remote food photographic method and 24-hr recalls) of professional soccer players (n = 6) of the English Premier League during a 7-day period consisting of two match days and five training days. On match days, average carbohydrate (CHO) content of the prematch (recovery from an evening kick-off) were similar (p > .05) though such intakes were lower than contemporary guidelines considered optimal for prematch CHO intake and postmatch recovery. On training days, we observed a skewed and hierarchical approach (p lunch (0.6 g·kg -1 )>breakfast (0.3 g·kg -1 )>evening snacks (0.1 g·kg -1 ). We conclude players may benefit from consuming greater amounts of CHO in both the prematch and postmatch meals so as to increase CHO availability and maximize rates of muscle glycogen resynthesis, respectively. Furthermore, attention should also be given to ensuring even daily distribution of protein intake so as to potentially promote components of training adaptation.

    Little is known about if and how team coaches disseminate nutrition information to athletes. In a census survey, New Zealand premier rugby coaches (n = 168) completed a psychometrically validated questionnaire, received by either Internet or standard mail (response rate, 46%), identifying their nutrition advice dissemination practices to players, their level of nutrition knowledge, and the factors determining this level of knowledge. The majority of coaches provided advice to their players (83.8%). Coaches responded correctly to 55.6% of all knowledge questions. An independent t-test showed coaches who imparted nutrition advice obtained a significantly greater score, 56.8%, than those not imparting advice, 48.4% (P = 0.008). One-way ANOVA showed significant relationships between total knowledge score of all coaches and qualifications [F(1,166) = 5.28, P = 0.001], own knowledge rating [F(3,164) = 6.88, P = 0.001] and nutrition training [F(1,166) = 9.83, P = 0.002]. We conclude that these rugby coaches were inadequately prepared to impart nutrition advice to athletes and could benefit from further nutrition training.

Material and methods: in this study, data were obtained from 120 players, who performed in competitions 90 minutes. The players were classified into 3 positional roles: defenders, midfielders and forwards. Technical performance variables analysis included: total passes, total successful passes, pass accuracy, total shots; total shots to target, shot accuracy, ball interception and ball losses. The data were statistically analyzed by one-way ANOVA, Kruskal-Wallis, Mann-Whitney U and Tukey post hoc test. Results : The findings of this study showed that players performed about 45 passes per competition. Midfielders and defenders had significantly higher number of passes than forwards. Pass accuracy was about 67% and there were no significant differences between positional roles. Also, the players performed about 0.8 shots per competition, forwards and midfielders had significantly higher number of shots than defenders. Shot accuracy was about 31%; midfielders and forwards had significantly higher shot accuracy than defenders. Forwards showed significantly lower ball interception and higher ball losses than other positions. Conclusion : The result of this study showed that there were significant differences between some technical actions in positional roles. Therefore, coaches can use this information for individualization of training according to playing positions and for optimization of training in the amateur game.

  4. Hydration of cations: a key to understanding of specific cation effects on aggregation behaviors of PEO-PPO-PEO triblock copolymers.

    This work reports results from the interactions of a series of monovalent and divalent cations with a triblock copolymer, poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (PEO-PPO-PEO). Phase transition temperatures of the polymer in the presence of chloride salts with six monovalent and eight divalent cations were measured using an automated melting point apparatus. The polymer undergoes a two-step phase transition, consisting of micellization of the polymer followed by aggregation of the micelles, in the presence of all the salts studied herein. The results suggest that hydration of cations plays a key role in determining the interactions between the cations and the polymer. The modulation of the phase transition temperature of the polymer by cations can be explained as a balance between three interactions: direct binding of cations to the oxygen in the polymer chains, cations sharing one water molecule with the polymer in their hydration layer, and cations interacting with the polymer via two water molecules. Monovalent cations Na(+), K(+), Rb(+), and Cs(+) do not bind to the polymer, while Li(+) and NH4(+) and all the divalent cations investigated including Mg(2+), Ca(2+), Sr(2+), Ba(2+), Co(2+), Ni(2+), Cu(2+), and Cd(2+) bind to the polymer. The effects of the cations correlate well with their hydration thermodynamic properties. Mechanisms for cation-polymer interactions are discussed.

    Encapsulation of extremely hydrophobic substances such as SN-38 into nanoparticles, is a promising approach to solve the solubility issue and enable drug administration. Moreover, nanocarriers' tumor homing behavior, targeted and controlled release at the site of action will optimize therapeutic potency and decrease toxicity of the incorporated drug substance. However, the enormous drug hydrophobicity might limit the capacity for encapsulation as the premature drug precipitation will contribute to fast free drug crystal growth, low drug incorporation and huge waste of the active material. In this article we defined the optimal region for manufacturing of SN-38 loaded PEO-PPO-PEO/P(DL)LCL nanoparticles (NPs) with high efficacy of encapsulation, suitable particle size and different surface properties, using D-optimal design and nanoprecipitation as production method. Further we made an approach to investigate the interactions with macromolecules at the nano-bio interface which are predetermined by the physico-chemical and surface properties of the NPs, and are important determinants for the biological identity of the nanoparticles, the potential for evasion of the physiological barriers and the efficacy of localization at the site of action. Here we present in depth analysis of the behavior of two types of nanoparticles with different surface properties through structured protein interaction and bioreactivity experiments in order to presuppose NP performance and toxicological profile in biological environment.

    The purpose of this study was to determine the epidemiology and history of knee injury and its impact on activity limitation among football premier league professional referees in Iran. This was a descriptive study. 59 Football Premier League professional referees participated in the study. The knee injury related information such as injury history and mechanism was recorded. Injury related symptoms and their impacts on the activity limitation, ability to perform activities of daily living as well participation in sports and recreational activities was obtained through the Knee Outcome Survey (KOS). The results indicated that 31 out of 59 participants reported the history of knee injury. In addition, 18.6%, 22.4% and 81% of the referees reported that they had been injured during the last 6 months of the last year, and at some point in their refereeing careers, respectively. Results further indicated that 48.8% of the injuries occurred in the non-dominant leg and they occurred more frequently during training sessions (52%). Furthermore, the value of KOS was 85 ± 13 for Activities of Daily Living subscale and 90 ± 9 for Sports and Recreational Activities subscale of the KOS. Knee injury was quite common among the Football Premier League professional referees. It was also indicated that the injuries occurred mainly due to insufficient physical fitness. Therefore, it is suggested that football referees undergo the proper warm-up program to avoid knee injury.

    Metallic plutonium was first prepared in France in January 1956, as soon as we had access to quantities of the order of several grams of plutonium, which had been extracted from the rods of the pile EL2 at Saclay. Since up to the present this reactor, of thermal power 2 000 kW, has been our only source of plutonium, we have so far only worked on experimental quantities sufficient for the basic tests but not for tests on a scale of possible applications. It is this work, carried out during this phase of preliminary research, which is described below. With the starting up of the plutonium extraction plant at Marcoule, where the reactor G1 has been operating at power for more than a year, we shall go on next to a another order of magnitude which will allow the manufacture and experimentation of prototype fuel elements. (author) [French] La premiere elaboration de plutonium metallique en France fut faite en janvier 1956, des que nous pumes disposer de quantites de plutonium de l'ordre de quelques grammes, qui avaient ete retires des barreaux de la pile EL2 de Saclay. Ce reacteur, d'une puissance thermique de 2 000 kW, ayant ete jusqu'a present notre seule source de plutonium, nous n'avons encore travaille que sur des quantites experimentales suffisantes pour les essais de base, mais non pour des essais a l'echelle d'applications possibles. Ce sont les travaux effectues pendant cette phase de recherches preliminaires qui seront evoques ci-dessous. Avec la mise eu route de l'usine d'extraction de plutonium de Marcoule, ou le reacteur G1 fonctionne en puissance depuis plus d'un an, nous allons passer prochainement a un autre ordre de grandeur, qui nous permettra la fabrication et l'experimentation d'elements combustibles prototypes.

    Football is increasingly used to facilitate recovery in mental health services, often in partnership with football clubs. However, few clubs have made mental health part of their corporate social responsibility programmes until recently. We report the impact on participants of the 'Imagine Your Goals' programme, run by 16 Premier League football clubs in conjunction with England's Time to Change programme to reduce mental health-related stigma and discrimination. Mixed methods evaluation used pre/post measures of well-being, access to social capital, focus groups held early on and towards the end of the two-year programmes, and questionnaires for coaching staff. There were no significant changes to participants' mental well-being scores between baseline and follow-up, nor to the total number of social resources accessible through their networks. However, there was a statistically significant increase at follow-up in the mean score of the personal skills subscale of the Resource Generator-UK. Participants' individual skills were also higher at follow-up. Qualitative data showed programmes had largely met participants' expectations in terms of socializing, providing structure and improving fitness levels, exceeded expectations in relationships with coaching staff and additional activities, but did not always meet them in improving football skills. Participants varied in their knowledge of exit opportunities, depending on which club's programme they attended. A minority of clubs reported difficulties in recruitment and concerns about planning for the future of the projects. Football clubs and the charitable foundations they set up can successfully deliver programmes to people with mental health problems which improve access to personal skills social capital and have other potential benefits.

  13. Mobil positioning itself to become Canada's premier oil and gas company

    To achieve its goal of becoming Canada's premier oil and gas company by the year 2000, Mobil Oil Canada is empowering its employees and applying appropriate technology to unlock resources and create value. Mobil produces 4.1 million m 3 of oil and natural gas liquids, 5.6 million m 3 /y of natural gas and 438,000 tonnes/y of sulfur. It also operates over 3,000 wells in western Canada and eleven gas processing plants, manages 1,700 km of pipeline, and has 33% interest in the Hibernia project on the Grand Banks. Oil lifting costs have decreased over the past three years from $3.40/bbl to $2.80/bbl and development costs are under $2/bbl. Innovative technology used to achieve high production and low costs include the use of three dimensional seismic surveys and horizontal drilling. Other techniques used at particular sites include installation of downhole injection regulators to control problems of segregation and metering between different water injection zones at the Carson Creek field, use of artificial lifts in gas wells, and a dual gas lift at the Rainbow Lake oil field. At the Lone Pine gas plant, the first Superclaus-99 sulfur recovery process was installed, reducing sulfur emissions by 60% and increasing recovery efficiency from 95% to 98%. Mobil has operated in Canada since 1940 and has made significant discoveries, including Canada's largest producing oil field, the Pembina. In 1971, Mobil discovered gas of commercial significance off the east coast and helped discover the Hibernia and Venture fields. The Hibernia project is scheduled to come on stream in 1997 and Mobil expects the economics of the project to be favorable, with a $12-13/bbl oil price needed to break even. 7 figs

Therefore, knowledge about the epidemiology of soccer injuries could allow sports-medicine professionals, such as physicians and physiotherapists, to direct their work in specific preventive programs. Thus, our aim was to conduct an epidemiological survey of injuries sustained by professional soccer players from the same team who participated in the Brazilian championship premier league in 2009. To this end, we evaluated retrospectively player medical records from the team, which included name, date of birth, position, date of injury, mechanism of injury, and type of injury. In the period of study, 95 injuries were recorded: 42 (44.2% were recorded during matches, and 53 (55.8% during the training period. Injuries occurred more frequently in midfielders and strikers. All injuries happened in the lower limb, most of the injuries were muscular, and most occurred as the result of collisions with other athletes. In summary, this study demonstrates that there is a need for greater safety awareness in the training environment. Keywords: injuries, epidemiology, soccer players

    Résumé Religion et guérisseurs traditionnels occupent encore une place prépondérante dans la prise en charge des maladies mentales à Madagascar. Ainsi, nous nous sommes fixés comme objectif d'établir un état des lieux sur les soins de premier recours des malades mentaux. Nous avons mené une étude rétrospective descriptive s'étalant sur une période de 16 mois allant de janvier 2014 en avril 2015 au sein du service de psychiatrie du CHU de Befelatanana à Antananarivo. La prévalence des psychoses était de 25%. Le genre féminin (53%), l'ethnie merina (77%), les étudiants (45%), le niveau d'étude secondaire (40%), les célibataires (72%), la religion protestante (45%), ainsi que le niveau socio-économique moyen (57,5%) étaient prédominants. Dans les paramètres cliniques, le mode de début brutal (52%), le premier recours à la religion (40%), la présence d'antécédents des cas similaire (90%), étaient majoritaires. La schizophrénie était la pathologie la plus rencontrée dans la moitié des cas. Le délai d'amélioration en cas de traitement religieux et traditionnels était dans la moitié des cas de plus de 10 jours d'hospitalisation. Les patients ayant reçu une prise en charge psychiatrique en premier recours, étaient améliorés dans 75 % cas en moins de 10jours. Le retard du recours aux soins psychiatriques est une réalité à Madagascar qui aggrave le pronostic des psychoses. PMID:29632623

    Individual differences in the growth and maturation have been shown to impact player performance and development in youth soccer. This study investigated Premier League academy players' experiences of participating in a tournament bio-banded for biological maturation. Players (N = 66) from four professional soccer clubs aged 11 and 14 years and between 85-90% of adult stature participated in a tournament. Players competed in three 11 vs 11 games on a full size pitch with 25-min halves. Sixteen players participated in four 15-min focus groups and were asked to describe their experiences of participating in the bio-banded tournament in comparison to age group competition. All players described their experience as positive and recommended the Premier League integrate bio-banding into the existing games programme. In comparison to age-group competitions, early maturing players described the bio-banded games more physically challenging, and found that they had to adapt their style of play placing a greater emphasis on technique and tactics. Late maturing players considered the games to be less physically challenging, yet appreciated the having more opportunity to use, develop and demonstrate their technical, physical, and psychological competencies. Bio-banding strategies appear to contribute positively towards the holistic development of young soccer players.

    2005-03-01

    After being appointed "premier physician" in 1731, Pierre Chirac, thanks to his influence with the king, tried to realize an ambitious project. Inspired by the creation of an Academie de Chirurgie by the "premier surgeon", Chirac decided to creation an Académie de Médecine in Paris. Under his guidance, it was planned to collect opinions from all doctors of the kingdom in order to enhance global knowledge of disease, symptoms and treatments. However, threatened with the loss of its secular superiority, the Paris University Medical School immediately opposed the project. Although well advanced, the project was finally abandoned on Chirac's death.

    Full Text Available ABSTRACT This article aims to analyze the technical performance of football teams in the FA Premier League during the 2015/2016 season. Data of twenty clubs over 38 matches for each club are considered using 23 variables. These variables have been explored in the football literature and address different features of technical performance. The different configuration of the data for teams in detached segments motivated the multi-criteria approach, which enables identification of strong and weak sectors in each segment. The uncertainty as to the outcome of football matches and the imprecision of the measures indicated the use of Composition of Probabilistic Preferences (CPP to model the problem. “R” software was used in the modeling and computation. The CPP global scores obtained were more consistent with the final classification than those of other methods. CPP scores revealed different performances of particular groups of variables indicating aspects to be improved and explored.

    Full Text Available Background: The clinical significance of glycemic index (GI and glycemic load (GL is inconclusive. Objective : This study was conducted to examine the association of GI and GL with clinical cardiovascular disease (CVD risk factors including body weight, blood pressure (BP, serum lipids, fasting glucose, insulin and homocysteine over time among the PREMIER participants. Design: PREMIER was an 18-month randomized lifestyle intervention trial, conducted from 2000 to 2002, designed to help participants reduce BP by following the Dietary Approaches to Stop Hypertension (DASH dietary pattern, losing weight, reducing sodium and increasing physical activity. GI and GL were estimated from 24 h diet recall data at baseline, 6 and 18 months after intervention. PROC MIXED model was used to examine the association of changes in GI or GL with changes in CVD risk factors. Results: A total of 756 randomized participants, 62% females and 34% African Americans and who averaged 50.0±0.3 years old and 95.3±0.7 kg, were included in this report. Neither GI nor GL changes was associated with changes in any risk factors at 6 months. At 18 months, however, the GI change was significantly and positively associated with total cholesterol (TC change only (p<0.05, β = 23.80±12.11 mg/dL or 0.62±0.31 mmol/L with a significant age interaction. The GL change was significantly associated with TC (p=0.02, β = 0.28±0.15 mg/dL or 0.01±0.00 mmol/L positively and with low density lipoprotein cholesterol (LDL-C changes negatively (p=0.03, β = − 0.01±0.00 mg/dL or −0.00±0.00 mmol/L, and significant age interactions were observed for both. Conclusion: GI and GL was associated with TC and LDL-C after controlling for energy, fat and fiber intake and other potential confounders and the associations were modified by age. Further investigation into this relationship is important because of its potential clinical impact.

    1979-10-01

    Full Text Available Des observations réalisées sur deux stations piscicoles de Madagascar, dans des étangs ne recevant ni engrais ni nourriture, révèlent qu'au cours de leur premier mois les alevins de carpe (C. carpio subissent des mortalités voi-sines de 50 %. Ces dernières sont encore plus élevées en début et en fin de saison de reproduction. Au début, les fortes mortalités sont dues à la température trop basse et aux disponibilités alimentaires insuffisantes ; en fin de saison de reproduction, la température trop élevée et la mauvaise qualité des œufs sont sans doute en cause. Une fumure adéquate des étangs de grossissement des alevins et une alimentation correcte des géniteurs permettront peut-être de diminuer ces mortalités.

    Background There is an established risk of injury to young athletes exposed to high training loads. Identifying and monitoring injury risk is essential to aid prevention. The aim of this study was to use the consensus statement to determine the incidence and pattern of injury in 1 English Premier League soccer academy during 1 season. Methods A prospective cohort study included 181 elite academy soccer players during the 2012–2013 season. Players were divided into 5 age groups between 9 and 18 years. The number, type and incidence of injuries were recorded during matches and training. Incidence was calculated per 1000 hours of exposure. Results 127 injuries occurred during 29 346 hours of soccer exposure. 72% of injuries were non-contact related. Under (U)18 players sustained the highest number of match injuries. U12–14 players sustained the highest number of training injuries and injuries overall. U16 players sustained the highest number of severe injuries, and U18 players sustained the highest number of moderate injuries. U18 players sustained the highest number of injuries/1000 hours of training and overall. U15 players sustained the highest number of injuries/1000 hours of matches, the highest number of recurrent injuries and the highest incidence of recurrence. The most common injuries were muscle injuries in U15 and U18 players. The most common injury location was the anterior thigh, with the majority of these occurring in training. Conclusions Using the consensus statement, this study used a repeatable method to identify the injury profile of elite academy-level soccer players. PMID:27900186

    2016-03-01

    Full Text Available Les partenariats public-privé (PPP sont un phénomène relativement récent dans le secteur de l’irrigation ; le projet El Guerdane au Maroc est ainsi le premier de son genre. Inauguré en 2008, le projet alimente en eau 10 000 ha de plantations d’agrumes. Les banques internationales de développement le présentent comme un succès, mais l’impact sur le développement local est, au mieux, mitigé. Alors que certains agriculteurs ont bénéficié de cette initiative, d’autres ont été marginalisés, en termes d’accès à l’eau, aux terres fertiles et au développement. Fondé sur des recherches de terrain extensives conduites entre 2005 et 2013, l’article révèle trois problèmes cruciaux du projet PPP : des effets souvent négatifs sur les revenus des acteurs et sur le développement ; un partage inégal des coûts, des bénéfices et des risques entre les secteurs public et privé ; un impact environnemental incertain. Sur la base de ces résultats, l’étude situe le projet dans le contexte plus large de l’évolution des rapports de force politico-économiques au Maroc.

    Acquiring accurate information on the spatio-temporal variability of soil moisture content (SM) and evapotranspiration (ET) is of key importance to extend our understanding of the Earth system's physical processes, and is also required in a wide range of multi-disciplinary research studies and applications. The utility and applicability of Earth Observation (EO) technology provides an economically feasible solution to derive continuous spatio-temporal estimates of key parameters characterising land surface interactions, including ET as well as SM. Such information is of key value to practitioners, decision makers and scientists alike. The PREMIER-EO project recently funded by High Performance Computing Wales (HPCW) is a research initiative directed towards the development of a better understanding of EO technology's present ability to derive operational estimations of surface fluxes and SM. Moreover, the project aims at addressing knowledge gaps related to the operational estimation of such parameters, and thus contribute towards current ongoing global efforts towards enhancing the accuracy of those products. In this presentation we introduce the PREMIER-EO project, providing a detailed overview of the research aims and objectives for the 1 year duration of the project's implementation. Subsequently, we make available the initial results of the work carried out herein, in particular, related to an all-inclusive and robust evaluation of the accuracy of existing operational products of ET and SM from different ecosystems globally. The research outcomes of this project, once completed, will provide an important contribution towards addressing the knowledge gaps related to the operational estimation of ET and SM. This project results will also support efforts ongoing globally towards the operational development of related products using technologically advanced EO instruments which were launched recently or planned be launched in the next 1-2 years.

    Full Text Available Orientation: Local football contributes significantly to the social- and economic welfare of South Africa through its spectators. Understanding the motives and experiences of football spectators could provide opportunities for capitalising on football as revenue stream feeding the South African economy. Research purpose: To investigate how motives for sport consumption predict intrinsic psychological reward of South African premier league football spectators. Motivation for the study: Sport - particularly football - is an untapped resource for stimulating economic development and growth through its consumers. Spectators, who often experience their investment in the sport as deeply rewarding and meaningful, should participate more frequently in purchasing products or services associated with the sport. Through understanding the motives for sport consumption of South African premier league football spectators and the impact of these motives on intrinsic psychological reward experiences, football clubs are able to provide a targeted experience or service to spectators in order to further stimulate economic growth. Research design, approach and method: A census sample of 806 football spectators attending various matches at a football stadium in Soweto was drawn. A cross-sectional research design was implemented. This research was exploratory and descriptive. Structural equation modelling was implemented to assess the factor structures of the constructs, to confirm composite reliability of the measures and to assess the structural paths between the variables. Main findings: A predictive model for intrinsic psychological rewards (life satisfaction and meaning through the motivation for sport consumption (individual – and game related factors was confirmed. It was further established that motivation for sport consumption is significantly positively a related to and b associated with the experience of intrinsic psychological reward by South African

    2007-12-01

    The aim of the present study was to examine the influence of first half activity, overall match intensity and seasonal variation on the physical match performances of English Premier League football referees. Match analysis data was collected using the Prozone match analysis system from 19 full-time professional referees during a total of 254 matches in the 2004-2005 season. Physical match performances were classified into three separate categories: 1, total distance covered (TD); 2, high-intensity running distance (running speed>5.5m/s, HIR); 3, average distance from infringements (DI). Using these match activity variables the influence of first half TD and HIR distances on second half activities and also the influence of players' match activities upon the referees' physical match performances were examined. The main finding of the present study was that the physical match performances of the referees were partly related to those of the players, in that the referees' HIR correlated with players' HIR (r=0.43, pphysical match performance of the referee. Further examination is required as to whether reduced physical performances in the second half of matches are a consequence of referee fatigue, tactical strategies on behalf of the referee or reduced player match activities resulting in a slower tempo of match.

    Full Text Available All football teams that compete within the F. A. Premier League possess an academy, whose objective is to produce more and better home-grown players that are capable of playing professionally. These young players spend a large amount of time with their coach, but little is known about player’s perception of the coach–athlete relationship within F. A. Premier League Academies. The objectives of this study were to examine whether perceptions of the coach–athlete relationship changed over six months and if the coach–athlete relationship predicted self-reported goal achievement among F. A. Premier League academy players. This study included cross-sectional (n = 104 and longitudinal (n = 52 assessments, in which academy soccer players completed a measure of the coach–athlete relationship and goal achievement across either one or two time periods. The cross-sectional data were subjected to bivariate correlations, whereas the longitudinal data were analyzed using multiple regressions. Perceptions of the coach–athlete relationship remained stable over time. The coach–athlete relationship predicted the achievement of mastery goals six months later. Enhancing the quality of the coach–athlete relationship among elite adolescent athletes appears to be a suitable way of maximizing mastery achievement goals, particularly among developmental athletes who participate in team sports.

On sait, grâce à la correspondance de l'auteur, qu'il avait pris la décision de réviser son texte dès 1783, en raison de sa candidature pour le poste d'Ambassadeur de France à Constantinople. Par contre, on n'en sait pas davantage sur le lieu et le temps exacts où il a travaillé les deux nouvelles versions, portant également la date 1782, ni d'ailleurs sur les circonstances de leur édition.

    The prevalence of male obesity is increasing but few men take part in weight loss programmes. We assessed the effect of a weight loss and healthy living programme on weight loss in football (soccer) fans. We did a two-group, pragmatic, randomised controlled trial of 747 male football fans aged 35-65 years with a body-mass index (BMI) of 28 kg/m(2) or higher from 13 Scottish professional football clubs. Participants were randomly assigned with SAS (version 9·2, block size 2-9) in a 1:1 ratio, stratified by club, to a weight loss programme delivered by community coaching staff in 12 sessions held every week. The intervention group started a weight loss programme within 3 weeks, and the comparison group were put on a 12 month waiting list. All participants received a weight management booklet. Primary outcome was mean difference in weight loss between groups at 12 months, expressed as absolute weight and a percentage of their baseline weight. Primary outcome assessment was masked. Analyses were based on intention to treat. The trial is registered with Current Controlled Trials, number ISRCTN32677491. 374 men were allocated to the intervention group and 374 to the comparison group. 333 (89%) of the intervention group and 355 (95%) of the comparison group completed 12 month assessments. At 12 months the mean difference in weight loss between groups, adjusted for baseline weight and club, was 4·94 kg (95% CI 3·95-5·94) and percentage weight loss, similarly adjusted, was 4·36% (3·64-5·08), both in favour of the intervention (pScottish Government and The UK Football Pools funded delivery of the programme through a grant to the Scottish Premier League Trust.

    The diel changes of the biochemical composition of the phytoplankton were studied in the Idriss first reservoir (located on the Inaouen river at thirty Km from the city of Fes, Morrocco) during September 1994. Several biomass and metabolic indicators (proteins, carbohydrates, lipids, chlorophyll a and primary production) were assessed every fourth hour over tow days (7, 8 and 9 September). Since the Protein/Carbohydrates ratio (P/C) is largely recognised as a good integrator of the metabolic functions of the cells, we examined its distribution pattern concomitantly with aforementioned parameters. The results demonstrated enhanced P/C ratios clearly indicating that nutrients were sufficiently available for growth. In addition, this index showed a diel significant variation with levels higher in the night than in the day. Moreover, these results suggest that phytoplankton species during the night used the day-synthesised carbohydrates to insure the cell metabolic functioning. The P/C presents relatively high values in proposition to the ones that have been recorded in temperate regions, and seems to be related to azotic inputs of the Inaouen river. Dans le but de parfaire nos connaissances sur le fonctionnement du sous écosystème phytoplancton, nous nous sommes intéressés à étudier son cycle nycthéméral et son métabolisme cellulaire dans la retenue du barrage Idriss premier. Cette dernière, construite sur l'Oued Inaouène, est située à une trentaine de Km de la ville de Fès. Au cours de ce cycle, les prélèvements ont été effectués selon une séquence temporelle de 4 heures pendant 48 heures, les 7, 8 et 9 septembre 1994. L'étude de l'évolution des composantes biochimiques des cellules phytoplanctoniques à savoir les protéines, les glucides et les lipides a permis de mettre en évidence des variations nycthémérales importantes. Ces variations sont d'autant plus importantes que les variations spatiales observées entre les profondeurs. De plus

    This case report illustrates and discusses the non-operative management of a complete anterior cruciate ligament (ACL) injury in an English Premier League football player, his return to play within 8 weeks and problem-free follow-up at 18 months post injury. When non-operative verses surgical ACL reconstruction is considered there are many fundamental gaps in our knowledge and currently, at elite level, there are no cases in cutting sports within the literature to guide these decisions. When the norm is for all professional footballers to be recommended surgery, it will be very challenging when circumstances and patient autonomy dictate a conservative approach, where prognosis, end points and risk are unclear and assumed to be high. This case challenges current dogma and provides a starting point for much needed debate about best practice, treatment options, research direction and not just at the elite level of sport.

    Campylobacter enteritis is a food-borne or waterborne illness caused almost exclusively by Campylobacter jejuni and, to a lesser extent, by Campylobacter coli. These organisms produce indistinguishable clinical diseases and together represent the second most common cause of bacterial diarrhea in the United States and the leading cause of enteric infection throughout the world. The conventional approach to the laboratory diagnosis of Campylobacter enteritis is based on the recovery of the organism from a stool specimen, which requires the use of a specialized medium incubated at 42°C for several days in an artificially created microaerophilic environment. Recently, several commercially available enzyme immunoassays (EIAs) have been developed for the direct detection of C. jejuni and C. coli in stool specimens. This study compared conventional culture with three EIA methods, the Premier CAMPY EIA (Meridian Bioscience, Cincinnati, OH), the ProSpecT Campylobacter EIA (Remel, Lenexa, KS), and the ImmunoCard STAT! CAMPY test (Meridian Bioscience, Cincinnati, OH), for the detection of C. jejuni and C. coli in 485 patient stool samples. Discordant results were arbitrated by using an in-house, real-time PCR assay that was developed and validated by a public health reference laboratory. Following analyses of the discrepant specimens by PCR, the sensitivity and specificity of both the Premier CAMPY and ProSpecT Campylobacter EIAs were 99.3% and 98%, respectively, while the ImmunoCard STAT!

    Campylobacter enteritis is a food-borne or waterborne illness caused almost exclusively by Campylobacter jejuni and, to a lesser extent, by Campylobacter coli. These organisms produce indistinguishable clinical diseases and together represent the second most common cause of bacterial diarrhea in the United States and the leading cause of enteric infection throughout the world. The conventional approach to the laboratory diagnosis of Campylobacter enteritis is based on the recovery of the organism from a stool specimen, which requires the use of a specialized medium incubated at 42°C for several days in an artificially created microaerophilic environment. Recently, several commercially available enzyme immunoassays (EIAs) have been developed for the direct detection of C. jejuni and C. coli in stool specimens. This study compared conventional culture with three EIA methods, the Premier CAMPY EIA (Meridian Bioscience, Cincinnati, OH), the ProSpecT Campylobacter EIA (Remel, Lenexa, KS), and the ImmunoCard STAT! CAMPY test (Meridian Bioscience, Cincinnati, OH), for the detection of C. jejuni and C. coli in 485 patient stool samples. Discordant results were arbitrated by using an in-house, real-time PCR assay that was developed and validated by a public health reference laboratory. Following analyses of the discrepant specimens by PCR, the sensitivity and specificity of both the Premier CAMPY and ProSpecT Campylobacter EIAs were 99.3% and 98%, respectively, while the ImmunoCard STAT! CAMPY test had a sensitivity of 98.5% and a specificity of 98.2%. By use of the PCR test as the reference standard, culture detected 127 of 135 Campylobacter-positive stool specimens, yielding a sensitivity of 94.1%.

    This report gives the results of radiation measurements carried out on the first C.E.A. swimming-pool pile, Melusine. The purpose of these measurements, which were carried out during the starting-up period and the first ascents to 1 MW power, is to check the radiation intensity levels near the pile and from this to verify the safety calculation methods used. In addition certain special measurements, such as those performed in and above the water of the swimming-pool, in the channels and outside them etc..., should make it possible eventually to define the conditions under which the pile may be used for special jobs with less protection. In the first part of the report are given the results of radiation measurements carried out during runs at low power plateaux not exceeding 500 W: in particular measurements at variable water levels in the water of the swimming-pool and on the axis of the open channels. The results given in the second part deal with radiation measurements performed in various parts of the premises, studies on the activation of the plugs in the experimental channels and of the materials in the forward compartment, and also of the radioactivity of the swimming-pool water and the air used to cool the channels.

    Full Text Available European top-level soccer clubs are continually looking for talented players. Few clubs, however, are willing to let youth players play at the highest senior level. Perhaps as a consequence, the search for talented players has resulted in an imbalance in the characteristics of these players, towards an overrepresentation of players born early in the selection year, an effect called the relative age effect (RAE. The RAE has been documented to be present among senior top-level players. Even so, few studies have investigated the effect among youth players at the senior level. The aim of this study is to examine RAE among U17-U20 players in the Norwegian premier league Tippeligaen in the 2009-2012 seasons. Participants were 315 male players born in 1990-1996. The results showed that 68% of the players were born in the two first quartiles of the year. The effect was even increasing in the four-year period. As we could expect based on the literature, the oldest players are given more playing time. However, the connection between playing time and RAE was inconsistent. Norwegian top-level soccer seems to be affected by the RAE when selecting their players. These players are not however guaranteed playing time because of the RAE.

    Full Text Available L’affaire Théophile est source de malentendus. Alors que l’historiographie du libertinage, en se concentrant sur le libertinage érudit a fini par oublier que la sodomie était un enjeu majeur du procès, les historiens de la répression homosexuelle abordent les relations sexuelles entre hommes dans une perspective essentialiste, gommant toute distinction entre sodomie au xviie siècle et homosexualité à l’époque contemporaine. Il s’agit donc la première partie de cet article de souligner que la sodomie est au cœur de l’affaire à la fois comme objet de représentation littéraire et comme pratique illicite. La seconde partie consiste dans une historicisation des discours ayant trait aux relations sexuelles entre hommes, qui montre qu’on ne saurait confondre « homosexualité masculine » et « sodomie ». Celle-ci désigne en effet des rapports anaux aussi bien entre hommes et femmes qu’entre hommes seuls ; lorsque la notion est mobilisée pour renvoyer à des relations anales entre hommes, elle ne constitue pas pour autant une orientation sexuelle ; en tant que concept issu de la théologie, elle ne relève pas de la sexualité ; aucune déviation de genre ne lui est associée. Dans une troisième partie, il s’agit de montrer que la notion de sodomie ne doit pas nous conduire à ignorer les autres discours pouvant porter sur les relations sexuelles entre hommes dans la France du premier xviie siècle et qu’à ce titre, on ne saurait se suffire de cette catégorie pour aborder la question. Bref, cet article a pour but de poser les premiers jalons d’une histoire de l’homosexualité masculine dans la France du xviie siècle d’un point de vue historiciste, sinon constructionniste.Sodomy in the Theophile de Viau affair: questions of gender and sexuality in early modern France.There is a puzzling misunderstanding about the Theophile affair.

La fouille a permis de préciser la fonction du fort, construit dans la deuxième moitié du XIIe s., à l’époque où Chinon est le centre administratif des possessions continentales des Plantagenêt, rois d’Angleterre. Du point de vue militaire, il formait une fortification avancée, protégeant le château principal, selon une structure que Richard Cœur de Lion appliquera au Château Gaillard. À l’intérieur, de vastes bâtiments constituaient des logis, conçus peut-être au départ pour héberger la chancellerie royale.This article presents the first results of the excavations undertaken in 2003 and 2004 over almost all of the Fort Saint-Georges at Chinon (Indre-et-Loire, one of three elements of the medieval fortress which dominates the town. The excavation enabled us to clarify the function of the fort, built in the 2nd half of the 12th century at a time when Chinon was the administrative centre of the continental possesions of the Plantagenet King of England. From a military point of view, it formed an advanced fortification protecting the main castle, within a structure that Richard the Lionheart would apply to the Chayeau Gaillard. Inside, some vast buildings made up the dwellings, designed perhaps initially to house the royal chanceller.

    It is clear that in the next decades there will be a substantial and increasing demand for uranium to fuel nuclear power stations. In a developing country, the discovery and development of uranium resources can be of importance either for the development of national nuclear power or for the commercial export of uranium. As the time taken between the start of a uranium exploration program and the uranium production stage.may be of the order of 6 - 10 years, it is now opportune to start new exploration so that advantage of the increased demand in the mid-1970s may be achieved. Thorium will also be of interest, but in the more distant future when the thorium cycle for advanced converters and breeder reactors is fully developed [French] Il est certain qu' au cours des prochaines décennies la demande d'uranium pour les centrales nucléaires sera importante et ne cessera de croître. Dans un pays en voie de développement, la découverte et la mise en valeur de ressources d'uranium peut avoir une grande importance, soit en vue de produire de l'énergie nucléoélectrique, soit en vue d'exporter l'uranium. Etant donné que les délais entre le démarrage d'un programme de prospection de l'uranium et le début de la production peuvent être de l'ordre de six ans, il est actuellement opportun de commencer les opérations d'exploration pour pouvoir profiter de la demande accrue qui s' affirmera vers le milieu de la prochaine décennie. Le thorium présentera aussi un certain intérêt, mais à plus long terme. Il faut pour cela que le cycle du thorium pour convertisseurs avancés et surgénérateurs ait été pleinement développé. (author)

    1996-01-01

    This paper gives an historical review of the discovery of antimatter. Nine anti-hydrogen atoms were produced in September 1995 by a German-Italian team using the CERN-LEAR. This exceptional event has convulsed the existing fundamental physics theories: the symmetry theory and the general relativity theory and its equivalence principle. The discovery of antimatter raises the question of the existence of an anti-universe and of where the antimatter could lie in the universe. The paper describes the experiment carried out at the CERN and the difficulties encountered for the measurement and the storage of antimatter particles. The possible forthcoming closure of the LEAR appears as a threat to future antimatter studies and developments using antimatter annihilation energy. (J.S.). 1 ref., 1 fig., 1 tab., 1 photo

    To investigate the challenges that men from hard-to-reach (HTR) populations encounter when attempting to commit to regular participation in physical activity and health behaviours, and to explore the psychological and social effects of participation in a twelve week football-led health improvement intervention. A twelve week football specific physical activity intervention targeting men from HTR populations was delivered by Everton Football Clubs' Football in the Community (FitC) scheme as part of a national programme of men's health delivered in/by English Premier League (EPL) football clubs. Men living in homeless shelters and/or recovering from substance misuse were recruited over a period of three months. The programme consisted of a two hour football session, twice weekly, alongside the dissemination of healthy living messages. Football sessions were conducted by a qualified FitC coach. This research was conducted during a twelve week period of immersed practitioner-research. Ethnographic and observational methodologies were adopted. Psychosocial issues were discussed with participants through informal client-researcher interactions and data were logged via field notes. Records of attendance were logged. Participants who failed to attend a session were contacted and their reason(s) for non-attendance were recorded. Data were analysed using deductive and inductive reasoning. Despite the apparent ambition of the participants to regularly participate in the FitC programme, adherence to the programme was poor. Economic, environmental and social barriers to engagement in the programme were apparent. Engagement in the programme resulted in positive psychosocial developments; the development of structure, social interaction and social capital. Community based football-led health improvement programmes endorsed by professional football clubs appear well positioned to connect with, and attract, men from HTR populations. The evidence suggests that such programmes can

The modifications to the protection devices that have been proposed after the measurements and the effect of these modifications on the results of the measures are given then. The regeneration process of a water purification chain has been examined from the radiation protection point of view. It has been possible to make some twenty radionuclides obvious in the produced effluents and to determine the volume activity of these effluents for each radionuclide.

Il faut signaler l’influence de la phrénologie. Ces médecins définissent des stigmates physiques et moraux propres à la pratique de la pédérastie, surtout passive et à l’occasion définissent un personnage type.

    Full Text Available Some twenty years after the Sultan of Brunei had bestowed upon the Englishman James Brooke the title of Rajah of Sarawak, giving him extensive authorities over a large tract of land, an American, Joseph William Torrey, United States consul in Brunei, gained the right to call himself Rajah of Marudu and Ambong. Though Torrey’s efforts failed to establish a profitable business in Sabah, they formed the root of the British North Borneo Company. Torrey probably was one of the last of his kind. Elsewhere in the Pacific, European and American residents and adventurers did not bother much about native titles, expanding their hold over land and its inhabitants by economic and political manipulation. In Hawaii and Samoa political reform and becoming cabinet minister or prime minister of a still independent island state served their purposes better.Quelque vingt ans après que le sultan de Brunei eut accordé à l’Anglais James Brooke le titre de rajah de Sarawak, qui lui donnait d’importants pouvoirs sur une vaste région, un Américain, Joseph William Torrey, consul des Etats-Unis à Brunei, obtint le titre de rajah de Marudu et Ambong. Les efforts de Torrey, échouant à établir une affaire profitable à Sabah, constituèrent néanmoins les bases de la British North Borneo Company. Torrey fut sans doute l’un des derniers de ce type d’aventuriers. Ailleurs dans le Pacifique, des résidents et des aventuriers européens et américains, par des manœuvres économiques et politiques, consolidèrent leur contrôle sur les territoires et leurs populations, sans trop se soucier d’obtenir des titres locaux. A Hawaii et à Samoa, il leur fut plus utile d’entreprendre des réformes politiques et de se pourvoir d’un poste de ministre ou de premier ministre d’un Etat insulaire encore indépendant.

    Introduction Le but de cette étude était de présenter les premiers résultats de diagnostic anténatal de la trisomie 21 par la technique d'hybridation in situ en fluorescence (FISH) au Maroc et discuter son intérêt dans le diagnostic rapide de cette aneuploïdie. Méthodes Ce travail a été réalisé chez 23 femmes avec des grossesses à haut risque de trisomie 21. La moyenne d’âge des gestantes étaient de 37,43 ans avec des extrêmes de 21 et 43 ans. Toutes étaient musulmanes mariées, mariage légitimé par la Charia, dont trois mariages consanguins, sauf une originaire de la République Démocratique du Congo qui était chrétienne et concubine. La majorité des femmes étaient fonctionnaires et avaient un niveau de scolarisation moyen à élevé. Toutes les patientes ont bénéficié d'une consultation de génétique médicale au cours de laquelle il leur a été donné des informations sur la technique, son intérêt et ses limites. Il s'agit de femmes enceintes qui avaient soit un âge maternel élevé ou des signes d'appel échographiques et/ ou biochimiques. Une des patientes était porteuse d'une translocation robertsonienne t(14;21) équilibrée. Une amniocentèse a été réalisée chez toutes les gestantes et aucun avortement n'a était induit par ce geste invasif. L’âge gestationnel moyen à la première consultation était de 14 semaines d'aménorrhée (SA) et à l'amniocentèse était de 16 SA et 5 jours. L'analyse FISH a été réalisée, après consentement des couples, sur des cellules non cultivées à partir des échantillons de liquides amniotiques, en utilisant des sondes spécifiques du chromosome 21. Résultats Parmi les 23 patientes qui ont bénéficiées d'un diagnostic anténatal de la trisomie 21 par la technique FISH, nous avons pu rassurer 21 d'entre elles, et nous avons détecté deux cas de trisomie 21 fœtal. Conclusion La technique FISH permet un diagnostic anténatal rapide, en moins de 48h, de la trisomie 21 sur

    Canada's first nuclear power station, the Nuclear Power Demonstration station (NPD), is intended to serve as a means of proof-testing the performance of the Canadian type of station using natural uranium as fuel and heavy water as moderator and coolant. It reached full power on 28 June 1962. Although designed for base-load operation it will, during the early stages, be operated part of the time on high-capacity.runs and part of the time on improvement periods. Progress has been favourable so far; the first high-capacity run of six weeks'duration yielded a capacity factor of 70%. Improvements already made have increased safety, improved performance and demonstrated potential methods of capital-cost reduction for future stations. For example, shaft seals on primary coolant pumps have been modified for better performance, freezer-type vapour recovery equipment has been replaced in favour of absorption columns to reduce heavy-water vapour loss, and flow limiters are being installed in sample lines to reduce losses of heavy water in the event of joint failures. During December 1962 two simultaneous leaks from the on-power refuelling machine led to an unusual sequence of events in which a considerable amount of hot high-pressure heavy water was spilled into the reactor vault where it suffered a slight downgrading in isotopic purity. It was upgraded and the reactor returned to operation by the end of the month. All safety devices operated correctly during the incident as did the provisions for containment of heavy water.

    Full Text Available 近年來受到國際大學評比及世界各國追求大學卓越政策的國際競爭趨勢影響,臺灣自2011年起推動「邁向頂尖大學計畫」。為了深入探討此政策背後潛藏的意識形態及價值預設,本研究採取後結構主義的理論觀點,並以論述分析的研究方法,以解構本政策中理所當然的本質性思維,並發掘政策論述中「權力/知識」的形構歷程,從而以位置性的概念,重新探索「邁向頂尖大學計畫」中的政策主體,並從不同位置去思考「邁向頂尖大學計畫」對於政策主體所具有的意義,進而反思主體突破結構限制的可能。 After being influenced in recent years by international university appraisals and the competitive trend toward the pursuit of excellence in countries all over the world, Taiwan has promoted a policy entitled the “Stepping towards Premier University Plan” since 2011. In order to thoroughly explore the underlying ideology behind this policy and its default values, this study takes a post-structuralism theoretical perspective, and uses discourse analysis to deconstruct the rationale of the policy. We uncover the process of construction of the “power / knowledge” discourse described in the policy, and thus from the positional concept, re-explore the policy body of the “Stepping towards Premier University Plan”. We consider the significance the “Stepping towards Premier University Plan” holds toward the policy body from different positions, and then reflect on the possibility of the policy body breaking through structural constraints.

    Full Text Available La lutte contre le décrochage des étudiants de premier cycle à l’université est aujourd’hui inscrite dans les politiques des pouvoirs publics. Si les causes multifactorielles de l’échec à l’université sont bien identifiées, les outils de remédiation visant à « raccrocher » les étudiants sont encore souvent à l’état d’expérimentation dans les universités françaises. Ainsi, un cycle d’orientation et de consolidation (COC a été mis en place à l’Université de Bretagne Sud (UBS en 2001 dans le but d’identifier et d’accompagner les étudiants potentiellement décrocheurs du premier semestre universitaire. Cette étude, à travers une enquête et des entretiens, vise à dresser un bilan de ce dispositif.Tackling the issue of first-year undergraduate withdrawal from university studies is today part of French public policies. Although the multifactorial causes of university withdrawal have been identified, the remediation tools for student retention are still often experimental in French universities. Thus, a study program for personal and vocational guidance called Cycle d’orientation et de consolidation (C.O.C. was set up at the Université de Bretagne Sud (UBS in 2001 to identify and guide potential first-semester university drop-out students. This study, through a survey and interviews, aims at assessing the program.

    Full Text Available La Fanciulla del West is a “horse opera” resulting from the second collaboration between David Belasco and Giacomo Puccini. This work, specially composed for the American stage, which had its world premiere at New York’s Metropolitan Opera in December 1910, paved the way for American composers who increasingly focused on American History in their quest for a “national” opera. For the first time, Puccini resorted to genuine Indian music, a Zuni melody, which he re-elaborated for dramatic purposes and associated with the nostalgic mood of uprooted people, the miners who left their home country for America. The Other – the native American viewed from the vantage point of the white, as well as the foreigner – no longer represented a threat, as had been the case in the operatic repertoire before, but became part and parcel of a multicultural society, like the Italian immigrant to whom Puccini also paid tribute. The Zuni melody, which opens and closes the opera, contributes to giving a genuine twist to a score which is the first one to tackle the foundations of the American nation.

    Full Text Available L’église St. Onuphre du monastère Lavrov (Ukraine occidentale, près de Staryi Sambir conserve des peintures murales qu’on a datées de la fin du XVe ou du début du XVIe siècle. Le but de la présente étude est de préciser les affinités d’ordre iconographique existentes entre les versions de l’«Hymne Acathiste» de Lavrov et des églises moldaves à peinture extérieure du temp du premier règne de Petru Rareş. Grâce à la rédaction de l’image de l’«Acathiste» de Probota, où le début du texte de la 17e strophe de l’«Hymne» est bien conservé, on peut constater qu’à Lavrov, dans l’image similaire, il ne s’agit pas de la 24e strophe de l’«Hymne» comme le croyait A. I. Rogov, maïs de la 17e strophe. Donc, on peut supposer, qu’à Lavrov il n’y avait pas de lacune dans la présentation des strophes 19–23 de l’«Hymne Acathiste».

    Full Text Available Undergraduates use a wide range of information resources for academic and nonacademic purposes, including web sites that range from credible, peer reviewed, online journal sites, to biased and inaccurate promotional web sites. Students are taught basic critical appraisal skills, but do they apply these skills to make decisions about information in different web sites? In an experimental setting, undergraduate students examined pairs of web sites containing conflicting information based on different aspects of critical appraisal, namely credibility of the author of the information, purpose of the web site, and last update of the site, and answered multiple choice questions about the conflicting information. Results indicated that students failed to use critical appraisal criteria, and that while knowledge of and self-reported use of these criteria were related to each other, they were not related to behaviour. This research demonstrates the need for alternative strategies for critical appraisal instruction and assessment. Les étudiants de premier cycle consultent une vaste gamme de sources d’information à des fins universitaires et non universitaires, y compris des sites Web allant de revues en ligne crédibles et évaluées par des pairs à des sites Web promotionnels partials et inexacts. On enseigne aux étudiants des méthodes de base d’évaluation critique, mais mettent-ils ces méthodes en pratique pour prendre des décisions relativement à l’information tirée de différents sites Web? Dans un cadre expérimental, les étudiants de premier cycle ont étudié des paires de sites Web contenant des informations contradictoires en se fondant sur différents aspects de l’évaluation critique, notamment la crédibilité de l’auteur de l’information, l’intention du site Web et la dernière mise à jour du site, et ont répondu à des questions à choix multiples concernant les informations contradictoires.

    The applicability of Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery scores to left main coronary artery disease (CAD) has been questioned. A simplified alternative is needed for guiding decision making. We evaluated the prognostic value of a simplified angiographic classification in comparison with a Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score-based approach for patients with left main CAD undergoing drug-eluting stent implantation. The proposed approach classified left main CAD as either extensive (n=819), defined as left main bifurcation lesions with an involvement of ostial left circumflex artery or as any left main lesion plus multivessel CAD, or limited (n=453), defined as ostial/midshaft lesions or left main bifurcation lesions without an involvement of ostium of left circumflex artery, alone or plus 1-vessel disease. The databases from 4 prospective Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease studies were pooled, and the primary outcome was a major adverse cardiac event, defined as death, myocardial infarction, or repeat revascularization. During follow-up (median 38 months; interquartile range, 36-61 months), the risk for major adverse cardiac event was significantly higher with extensive than with limited left main CAD (adjusted hazard ratio, 2.13; 95% confidence interval, 1.54-2.94; P Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score tertiles did not effectively stratify these 2 outcome measures. Compared with Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery scores, the simpler angiographic approach provided better discrimination for future cardiovascular events in patients with left main CAD undergoing drug-eluting stent implantation. © 2018 American Heart Association, Inc.

    Electrostatic periodic perturbations producing a resonance effect with Larmor motion, are applied for trapping 1.8 keV electrons in a magnetic mirrors bottle. This method gives temporary trapping lasting more than 20 transits. Switching off the perturbations results in complete trapping of temporarily trapped particles. Life time of fast electrons with a pressure of 5.10{sup -9} mm Hg has a value of 12 ms which seems to result from non adiabatic effect losses. At the same pressure, ionization of residual gas by fast electrons produces secondary electrons with a lifetime of 1.5 second in agreement with evaluations based on elastic scattering losses assumption.

    The impact of the Fukushima accident has been the willingness to implement passive safety measures in reactor design and to simplify reactor design itself. Within this framework, a new fuel element, named SAFE (Safety Added Fuel Element) based on the concept of accident tolerant fuel, is presented. SAFE is a new type of fuel element cooled internally and externally by light water and with stainless steel as the cladding material. The removal of boron may trigger a series of changes which may simplify the system greatly. A simplified thermal analysis of SAFE shows that the fuel centerline temperature is well below the maximal limit during the normal operation of the plant

  16. A premier analysis of supersymmetric closed string tachyon cosmology

    2018-04-01

    From a previously found worldline supersymmetric formulation for the effective action of the closed string tachyon in a FRW background, the Hamiltonian of the theory is constructed, by means of the Dirac procedure, and written in a quantum version. Using the supersymmetry algebra we are able to find solutions to the Wheeler-DeWitt equation via a more simple set of first order differential equations. Finally, for the k = 0 case, we compute the expectation value of the scale factor with a suitably potential also favored in the present literature. We give some interpretations of the results and state future work lines on this matter.

    Kahl, being the first European private atomic power station, has been operating at load since June 1961. Kahl is equipped with a boiling-water reactor, operating in an indirect cycle and with natural circulation. Its electrical net capacity is 15 MW, and the power produced until February 1963 amounts to 140 million kWh. In the paper the operating experience, particularly the extensive testing programme such as concerning transient behaviour and gammascanning, will be reviewed. Results about the operating performance of certain plant components such as control-rod-drive system, off-gas system and turbine will be presented. After this testing programme the plant has been operated at base load for some time in order to obtain realistic experience on fuel performance. After completion of the base-load phase of operation a nuclear superheating test loop will be installed and run in the Kahl reactor.

    An account is given of the experimental principles underlying the production process of a UO{sub 2} pellet plant. In this process, advance determination of the particle-size distribution characteristics of the raw material is secured not by means of controlled precipitation but by the crushing and grading of powders. The uranium oxides tested in this work are conventional materials, representing types of fabrication which differ by origin and method used. A study of the pellets obtained shows the potentialities and limitations of each type of oxide in the process adopted. A description is given of the characteristics of the powders as regards specific area, particlesize distribution, differential and thermogravimetric thermal analyses, and stoichiometry, and of the density, contraction, structure and stoichiometry of the pellets.

    Full Text Available The purpose of this study was to examine the progress of a class of third- and fourth-year undergraduate science students as they attempted to create a knowledge building community in a blended or hybrid science education class. The research sought to examine this process through analyses of the frequency of their note postings and responses, and through a social network analysis of their communication patterns for note reading. These data were automatically harvested by the Knowledge Forum knowledge building environment, and downloaded for later analysis. Contribution levels indicated that the frequency of note postings increased three-fold following the mid-term of the course causing maladaptive student work patterns to reduce information overload. As well, the disparity between high-frequency note posting students and low-frequency note posting students followed a linear curve with the ratio between the highest posting and lowest posting student to be 2.7:1. A similar pattern was found with regard to responses. A disparity was also found among the students in the number of postings read, with the highest note reading student reading six times the number of notes as the lowest note reading student.The social network analyses revealed evidence of community formation in the note reading network. Analysis showed both one-way and reciprocal interactions, indicating that the pathways needed for the transfer of complex information were present. Considering all the data together, while some communication patterns necessary for a knowledge building community were present, contribution patterns suggested that a true knowledge building community did not form, but that there was progress towards it. Cette étude avait pour objet d’étudier la progression d’un groupe d’étudiants en sciences de troisième et de quatrième années du premier cycle universitaire dans leur tentative de créer une communauté d’apprentissage dans une classe hybride d

    Full Text Available L'impact chimique et physique de la sédimentation sur la survie d'oeufs de Salmonidés a été étudié dans la partie amont de deux ruisseaux d'un même bassin à production salmonicole contrastée : le Moulinet qui présente une faible population de truites et la Roche qui est un ruisseau très productif. Les matières en suspension et les sédiments déposés ont été collectés à un pas de temps de 8 ou 15 jours en 1996 et 1997 et les survies embryo-larvaires ont été estimées en parallèle, dans des incubateurs artificiels. Les taux de survie ont été déterminés à l'émergence en 1996 et de la fécondation à l'éclosion, puis de l'éclosion à l'émergence en 1997. Les paramètres chimiques de l'eau interstitielle (oxygène, pH, nitrates, nitrites et ammoniac ont été mesurés au pas de temps de la semaine pendant la période d'incubation 1997 sur des dispositifs enfouis dans le substrat du ruisseau et au moment de l'éclosion dans les incubateurs contenant les oeufs. Les premiers résultats montrent que les taux de survie embryo-larvaires sont nuls en 1996 et faibles en 1997 (0 à 11 %, moyenne : 3,3 % dans le ruisseau du Moulinet alors que parallèlement, la survie est de 20 % sur un incubateur en 1996 et varie de 0 à 23 % en 1997 (moyenne : 7,7 % dans le ruisseau de la Roche. De l'éclosion à l'émergence, les survies sont supérieures à 80 % dans les deux ruisseaux. La sédimentation est contrastée sur les deux sites, plus forte en masse dans le ruisseau de la Roche pendant la période d'incubation mais de granulométrie beaucoup plus grossière que dans le ruisseau du Moulinet (sableuse dominante contre argilolimoneuse. Les teneurs en oxygène dissous mesurées dans le substrat de la Roche restent élevées pendant toute la période d'incubation (teneur minimum de 5 mg/l et sont significativement supérieures à celles mesurées dans le ruisseau du Moulinet pendant la deuxième partie de l'incubation 1997.

El estudio comparado de los resultados de estos diversos examenes ha permitido deducir ciertos hechos relativos a la contaminacion interna debida a la precipitacion radiactiva: 1. El cesio-137 es el unico radioisotopo artificial cuya presencia queda constantemente demostrada por el examen antropogammametrico. La variacion del valor medio de la carga corporal total puede ser observada durante todo el perfodo que-abarca el conjunto de los examenes. Ademas, es posible comprobar la variacion, por otra parte bien conocida, de la carga radiactiva en funcion del sexo. 2. los autores han podido estudiar la relacion existente entre la excrecion urinaria de cesio-137 y la carga total de este isotopo en el organismo, en correspondencia con las debiles actividades que se registran habitualmente. Los resultados parecen confirmar las relaciones establecidas por otros autores para grados de contaminacion mas elevados. 3.

    A stable and eco-friendly anion-exchange membrane (AEM) was prepared and applied in a non-aqueous all-copper redox flow battery (RFB). The AEM was prepared via a simple procedure, leading to a cross-linked structure containing quaternary ammonium groups without involvement of harmful trimethylamine. A network was thus constructed which ensured both ion transport and solvent resistance. The ion exchange capacity (IEC) of the membrane was tuned from 0.49 to 1.03 meq g-1 by varying the content of the 4, 4‧-bipyridine crosslinking agent. The membrane showed a good anion conductivity and retention of copper ions. As a proof of principle, a RFB single cell with this crosslinked membrane yielded a coulombic efficiency of 89%, a voltage efficiency of 61% and an energy efficiency of 54% at 7.5 mA cm-2.

    The fuel element for the first charge of EL4 makes use of stainless steel cans. The grade of steel chosen and the can thickness depend on the corrosion resistance and mechanical strength required. The operating stresses and temperatures are such that fabrication of a can lasting throughout the life of the fuel element calls for a highly resistant grade of steel, of thickness greater than 0.5 mm. When the can bears on the fuel as a result of creep, deformation in diametrical clearance may lead to ovalization and folding, while deformation in longitudinal clearance may cause buckling of the can. Numerous tests have been carried out on cans of thickness 0.3 and 0.4 mm to determine type of deformation as a function of clearance. To be certain of avoiding ovalization with the thicknesses proposed and to keep the internal temperature of the fuel as low as possible, the clearance must be reduced to zero in fabrication. (author) [French] L'element combustible du premier jeu EL4 utilise des gaines en acier inoxydable. Le choix de la nuance et de l'epaisseur de la gaine est lie a des considerations de tenue a la corrosion et de tenue mecanique. Les contraintes et les temperatures d'utilisation ne permettent pas de concevoir une gaine resistante pendant toute la vie de l'element combustible a moins d'utiliser une nuance tres resistante et d'epaisseur superieure a 0,5 mm. On admet que la gaine s'applique par fluage sur le combustible: la deformation dans les jeux diametraux peut conduire a la formation d'une ovalisation et d'un pli; la deformation dans les jeux longitudinaux peut conduire a des flambages de la gaine. De nombreux essais ont ete realises sur des gaines d'epaisseurs 0,3 et 0,4 mm pour connaitre le mode de deformation en fonction des jeux. Pour etre certain de ne jamais avoir d'ovalisation avec les epaisseurs envisagees, et pour avoir la temperature a coeur du combustible la plus basse possible, on est conduit a reduire a zero le jeu en fabrication.

In a nostalgic culture in search of ‘traditional’ English heroes, Terry is celebrated for his physicality and traditionally ‘English’ style of play; yet, his off-field behaviour is seen to be both emblematic and symptomatic of a celebrity culture considered to betray the val...

    Full Text Available The very special manner in which the First Ecumenical Council was reproduced at Suceviţa – the presence of Empress Elena next to Constantine and their association with the cross between them, The Vision of St. Peter from Alexandria, the moment when Arius was spanked by St. Nicholas who holds his beard and the unique episode of Arius’death in a public latrine as a result of his unbelief – reflects on one hand, the connection of the Council with the Liturgy and with the Trinity dogma and, on the other hand, they emphasize the victory of the true faith defended at Nicaea. It was the confession of this faith that brought the sacrifice of the Saints from the Menology, an amply painted theme on all walls of the narthex.

  13. Virtual accelerator concept, implementation and preliminary test; Accelerateur virtuel Concept, implementation et premier test

    A virtual accelerator is the coupling of a simulation code with the control system of a real machine. 3 operating modes are considered. First, the monitoring mode in which any action on the control system has an impact on both real and virtual machines. This mode allows a direct comparison between simulation results and the real behaviour of the accelerator. Secondly, the flight simulation mode, this mode allows the accelerator operators to simulate the effect of any change in the parameters of the control system before transferring them to the real machine. The main advantage of this mode is to allow the assessment of operating procedures before implementing them on the real machine. The third mode is the automatic steering mode in which the simulation code assumes the reins of the control system of the real machine. This mode allows the making of complex and time-consuming adjustment procedures in an automatic way. TraceWin is a simulation code dedicated to the behaviour of charged-particle beams in a linear accelerator. TraceWin is consistent with the EPICS technology on which the control system of most accelerators is based. A virtual accelerator composed of the SILHI injector combined to the TraceWin code via the EPICS environment has showed its efficiency in the automatic steering mode. (A.C.)

  2. Issues in the Learning Context of Undergraduate Physiotherapy Programme at a Premier Medical School in Zambia

    Directory of Open Access Journals (Sweden)

    Christian C Ezeala

    2018-01-01

    Full Text Available Background: Students’ perceptions of their learning environments influence their approaches to learning and the learning outcomes, and reflect a programme’s effectiveness. In Africa, literature on the learning environments of medical and health sciences education is scanty, and the issues impinging on effective education are not well documented. The objective of this study was to determine learners’ perceptions of the issues in the learning environment of undergraduate physiotherapy education at the University of Zambia.Methods: Undergraduate physiotherapy students in years 2 to 5 were stratified according to level of study and randomly sampled. They were provided written information about the study, and consenting students were allowed to complete the DREEM questionnaire unassisted. Completed questionnaires were rated using a recommended guideline and their responses analysed quantitatively. Global, subscale, and item mean scores were calculated, and Cronbach’s alpha was determined as a measure of data reliability and internal consistency. The study was approved by ethics committees of two universities.Results: Ninety-three students participated in the study. The response rate was 88.4 %. All classes rated the learning environment as ‘more positive than negative,’ with a mean global score of 123.2/200 (61.6 %. Scores within subscales (55.7–70.4 % were comparable across the classes. Nine items scored below 2.0/4.0 indicating dissatisfaction. These included inadequate social support, teacher authoritarianism, and factual overload. Cronbach’s alpha for global scores was 0.896, and between 0.616 and 0.820 for subscale scores.Conclusion: Though total DREEM scores showed overall positive perception of the learning environment by the students, item analysis showed students’ dissatisfaction with several aspects. This analysis of undergraduate students’ perceptions of the Physiotherapy learning environment provided insight into the phenomena in the programme and adds to the literature on learning environments of Physiotherapy education in Africa.Keywords: DREEM, EDUCATIONAL ENVIRONMENT, PHYSIOTHERAPY, TEACHING AND LEARNING, UNDERGRADUATE STUDENTS

    Full Text Available La civilisation des gobelets campaniformes a posé aux préhistoriens, dès son individualisation même, des problèmes de géographie et de diffusion ainsi que des questions de caractère chronologique. C'est essentiellement le mérite des auteurs ibériques d'avoir montré que cette culture s'était fractionnée en ensembles géographiques relativement distincts (P. Bosch-Gimpera, A. del Castillo. Les auteurs anglo-saxons, pour leur part, ont surtout mis l'accent sur les variantes typologiques, en essayant de décortiquer la famille campaniforme en horizons stylistiquement et chronologiquement bien différenciés. Au terme d'une longue tradition (marquée par les travaux de A. Goetze, P. Reinecke, J. Abercromby, V. G. Childe, H. N.

  13. PECVD de composes de silicium sur polymeres: Etude de la premiere phase du depot

    Science.gov (United States)

    Dennler, Gilles

    Since their first introduction in the early 90's, transparent barriers against oxygen and/or water vapor permeation through polymers, such as SiO 2, are the object of increasing interest in the food and pharmaceutical packaging industries, and more recently for the encapsulation of organic-based displays. It is now well known that these thin layers possess barrier properties only if they are thicker than a certain critical thickness, dc. For example, dc is around 12 nm in the case of SiO2 on KaptonRTM PI; below this value, the measured "Oxygen Transmission Rate" (OTR, in standard cm3/m2/day/bar) is roughly the same as that of the uncoated polymer. Until now, no detailed research has been carried out to explain this observation, but a hypothesis was proposed in the literature, based on island-like growth structure of the coating for d ≤ dc. According to this hypothesis, the surface energy of the polymeric substrates is so low that the Volmer-Weber (island-coalescence) growth mode occurs. We have aimed to verify this explanation, that is, to study the initial phase of silicon-compound (SiO2 and SiN) growth on four different polymeric substrates, namely polyimide (KaptonRTM PI), polycarbonate (LexanRTM PC), polypropylene (PP), and polyethyleneterephthalate (MylarRTM PET). Three different deposition methods were used, namely reactive evaporation of SiO, radio-frequency (RF) Plasma Enhanced Chemical Vapor Deposition (RF PECVD), and Distributed Electron Cyclotron Resonance (DECR) PECVD. In this latter case, the substrates were placed in three different positions: (i) in the active glow zone, (ii) downstream, and (iii) downstream, but shielded from photon emission (e.g. VUV) from the plasma. Angle-Resolved X-Ray Photoelectron Spectroscopy (ARXPS), Rutherford Backscattering Spectroscopy (RBS), and Scanning Electron Microscopy (SEM), the latter performed after Reactive Ion Etching (RIE) by oxygen plasma, revealed that growth indeed occurs in a Volmer-Weber mode in the case of evaporated films. The island coalescence was observed to occur at d = 1.2 nm, at which point the sticking coefficient of precursor species changes drastically. Finally, we have investigated the presence of an "interphase" between deposited coatings and the polymeric substrate. (Abstract shortened by UMI.)

    2013-01-01

    Gaharu resin is derived from Aquilaria sp. or Agar wood tree in a tropical ecosystem. In Malaysia the Aquilaria species especially A. malaccensis in danger of extinction in the wild due to illegal logging as its resin is highly used for the production of greatly valued incense throughout Asia. A significant tool in fingerprinting the species is through molecular activities of Polymerase Chain Reaction (PCR) application on which requires total genomic DNA as a starting material. This paper, described optimizations of both fresh and dried samples derived from A. malaccensis for genomic DNA. Three main parameters for the optimization were temperature (60, 65, and 70 degree Celsius), incubation period (30, 60, 90 minutes) and concentration of CTAB (1 %, 3 %, 5 %). The experimental design in these work resulted a total of 46 combinations of the parameters in which 0.5 g samples was used in each combination. Nano-drop spectrometer was used in detecting the quantitative genomic DNA at ng/ μl. In fresh samples, incubation temperatures at 65 degree Celsius for 60 minutes in 3 % were yielded 723.2 ng/ μl genomic DNA. Whereas, for dried samples, incubation temperature at 70 degree Celsius for 90 minutes in 5 % CTAB were yielded 70.2 ng/ μl of genomic DNA. Spectrometer reading at OD280/ 260 was 1.9 for both type of samples. The isolated genomic DNA is useful for the molecular activities to identify specific plants between the same species or among the Aquilaria species. (author)

    Urbain-Jean-Joseph Le Verrier was born in Saint-Lô on March 11, 1811. He entered the "École polytechnique" in 1831, from which he was to emerge eighth of his class two years later. After first devoting himself to chemistry, in 1836 he obtained a position as an astronomy assistant at the "École polytechnique". This choice will decide his future career, which culminates with the discovery of Neptune in 1846. Le Verrier wrote more than 200 contributions to the Comptes rendus de l'Académie des sciences. These contributions are very varied: some original articles, but also reports on publications published elsewhere, sometimes even simple notes of a single page. The whole set gives a very vivid vision of the development of the science of the 19th century. At that time, the Comptes rendus are really a reflection of the debates of the sessions of the Academy. They are published very quickly, and leave a large freedom of speech to the authors. They are therefore a snapshot of the sometimes lively polemics that animated the sessions of the French Academy of Sciences. In this limited essay, we will mainly look at the first years of the career of Le Verrier until the discovery of Neptune.

    Mineral raw materials come from fossil reserves or ores resulting from the geologic and climatic history of the Earth. The access to economic development for 80% of the worldwide population and the high rate of demographic growth (probably 8 billions of inhabitants in 2025) are important factors that can greatly multiply the worldwide consumption of ores. In parallel, environmental concerns and the increasing need for a better equilibrium between wildlife preservation and the supply of economic needs, lead to a more reasonable and mastered use of natural resources. The aim of this book is to shade light and give global elements of thoughts on mineral resources, and for the main of those (about 30 metals and mineral substances), to review the most useful data and references about their production and consumption. For each question, chapters are devoted to the situation of France in its worldwide context. One chapter concerns the uranium ores (reserves, production, prices evolution, consumption, economic flux and companies involved). (J.S.).

    Full Text Available Introduction: Selection of optimal nutrition for physical activity of sportsmen depends on several factors, and includes the type and duration of exercises, total energy consumption, time needed for recovery, andnutritional preferences. Proper nutrition of sportsmen relies on adequate combination and participation of all the macronutrients. The aim of this research was to analyse and determine the nutritional awareness andhabits of sportsmen depending on their age and type of sports they indulge.Methods: This is a cross-sectional, descriptive, and analytical study undertaken from May to July 2011 on the sample of 100 examinees/sportsmen of the Football Club “Željezničar“ and Basketball Club “Bosna“.Results: General awareness of sportsmen on basic principles of proper nutrition is unsatisfactory. Statisticalsignificance per type of sport and age of sportsmen is proved through representation of macronutrients in their nutrition. For 49.1% footballers and 52% sportsmen over 19 years of age the most important combinationof macronutrients resembles the model of carbohydrates-proteins-fats, while 48.9% of basketballers and sportsmen under 18 prefer proteins-carbohydrates-fats. The study had shown a statistically significantdifference (p=0.01 between the footballers and basketballers with regard to the type of meal they consume before the trainings.Conclusion: Insufficient knowledge on the subject reflects in bad nutritional habits, especially those related to the number and arrangement of daily meals in comparison to respective sports activities.

    The emergence of power exchanges is one of the key phenomena accompanying the liberation of the electricity industry. Apart from the Nordic countries, this is a recent event, especially for the countries of continental Europe. In this study, we will be focusing on the German electricity market for several reasons. Firstly, Germany has the largest market for electrical power in Europe. As the electricity sector is in the process of opening up to competition, this country is one of the 'good pupils' in the field of electrical deregulation. Next, it is a good idea to draw up an initial overview of the German experience following the launch on 27.11.2001 of an organised market in France (the PowerNext exchange). Currently, there are three exchanges able to negotiate contracts in the German hub: the Amsterdam Power Exchange (APX), the European Energy (EEX) and the Leipzig Power Exchange (LPX). The exchanges were created between May 1999 (APX) and August 2000 (EEX). They are in a situation of direct competition in the German market. This competition is particularly keen since the three players are well aware of the challenge at stake: becoming the leading exchange for the German market and (possibly) in a future integrated European market. The announcement of a merger between LPX and EEX in 2002 (published on 26.10.2001 on the sites of both exchanges) underlines the importance of these strategic issues. The purpose of this work is to carry out an assessment of the three exchanges during their first months in existence. Using an econometric analysis, we offer conclusions concerning the capacity of these exchanges to supply a reference price. The opportunities for arbitration are also examined. Despite the difficulties of the market launches, the exchanges have successfully maintained a certain degree of coherence in their prices and may now sit back a little and plan their expansion. It is difficult at this stage to see who the eventual 'winner' will be. The discussion which concludes this work nevertheless gives certain indications on this point. (author)

    Full Text Available The coinages of the Taifas still constitute an invaluable source of historical information, extremely useful for the study of the political and ideological evolution of al-Andalus after the fall of the Caliphate. The coins of the Hūdides of Saragossa, and particularly those struck by the founder of this dynasty Sulaymān al-Musta‘īn are a good example of what the different inscriptions on coins can tell us concerning the political situation in the first years of this dynasty. This article deals with a particular and rare type of silver coins attributed to the first Hūdide, Sulaymān, that holds a very problematic Shiite slogan (related to the Wilāya of ‘Alī, and tries to discuss its ideological significance and the different political circumstances that might have justified its appearance on this type of issues.

Este artículo se centra en un singular tipo de monedas de plata atribuidas al primer hūdí, Sulaymān, que muestra un lema šī‘í, relacionado con la wilāya de ‘Alī, problemático en extremo, ofreciéndose un estudio sobre su significación ideológica y las diferentes circunstancias políticas que pudieron haber justificado su aparición en esta emisión.

Global interest in the application of natural gas (NG in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. Many technological solutions are currently considered on the market or in development, which address the challenge and opportunity of NG. In this paper, a decision support system (DSS is introduced for selecting the best fuel to develop in the value chain of NG through four options, namely compressed NG (CNG, liquefied NG (LNG, dimethyl ether (DME, and gas-to-liquids (GTL. The DSS includes a model which uses the technique for order performance by similarity to ideal solution (TOPSIS to select the best fuel in the value chain of NG based on the attributes such as market situations, technology availability, and transportation infrastructure. The model recommends some key guidelines for two branches of countries, i.e. those which have NG resources and the others. We believe that applying the proposed DSS helps the oil and gas/energy ministries in a most effective and productive manner dealing with the complicated fuel-related production and transportation decision-making situations.

    Human chromosomes 1q21–q25, 6p21.3–22.2, 9q33–q34, and 19p13.1–p13.4 carry clusters of paralogous loci, to date best defined by the flagship 6p MHC region. They have presumably been created by two rounds of large-scale genomic duplications around the time of vertebrate emergence. Phylogenetically, the 1q21–25 region seems most closely related to the 6p21.3 MHC region, as it is only the MHC paralogous region that includes bona fide MHC class I genes, the CD1 and MR1 loci. Here, to clarify the genomic structure of this model MHC paralogous region as well as to gain insight into the evolutionary dynamics of the entire quadriplication process, a detailed analysis of a critical 1.7 megabase (Mb) region was performed. To this end, a composite, deep, YAC, BAC, and PAC contig encompassing all five CD1 genes and linking the centromeric +P5 locus to the telomeric KRTC7 locus was constructed. Within this contig a 1.1-Mb BAC and PAC core segment joining CD1D to FCER1A was fully sequenced and thoroughly analyzed. This led to the mapping of a total of 41 genes (12 expressed genes, 12 possibly expressed genes, and 17 pseudogenes), among which 31 were novel. The latter include 20 olfactory receptor (OR) genes, 9 of which are potentially expressed. Importantly, CD1, SPTA1, OR, and FCERIA belong to multigene families, which have paralogues in the other three regions. Furthermore, it is noteworthy that 12 of the 13 expressed genes in the 1q21–q22 region around the CD1 loci are immunologically relevant. In addition to CD1A-E, these include SPTA1, MNDA, IFI-16, AIM2, BL1A, FY and FCERIA. This functional convergence of structurally unrelated genes is reminiscent of the 6p MHC region, and perhaps represents the emergence of yet another antigen presentation gene cluster, in this case dedicated to lipid/glycolipid antigens rather than antigen-derived peptides.

    Directory of Open Access Journals (Sweden)

    Deeksha Pandey

    Full Text Available BACKGROUND: As preventing cancer with the help of a vaccine is a comparatively new concept, awareness and education about it will have important implication in the implementation of this strategy. MATERIALS AND METHODS: Present explorative questionnaire based survey included 618 MBBS students for final analysis. RESULTS: Majority of participants (89.6% were well aware of the preventable nature of cervical cancer. Most of them (89.2% knew that necessary factor responsible for cervical cancer is infection with high risk HPV. Awareness regarding the availability of vaccine against cervical cancer was 75.6%. Females had a better awareness regarding availability of vaccine, target population for vaccination and about the catch up program. Overall acceptance of HPV vaccine among the population studied was 67.8%. Medical teaching had a definitive impact on the understanding of this important public health issue. Females seemed to be more ready to accept the vaccine and recommend it to others. For our study population the most common source of information was medical school teaching. Majority of participants agreed that the most important obstacle in implementation of HPV vaccination program in our country is inadequate information and 86.2% wanted to be educated by experts in this regard. CONCLUSION: HPV vaccine for primary prevention of cervical cancer is a relatively new concept. Health professional will be able to play a pivotal role in popularizing this strategy.

    Professional soccer players are exposed to large amounts of physiological and psychological stress, which can increase infection risk and threaten availability for training and competition. Accordingly, it is important for practitioners to implement strategies that support player well-being and prevent illness. This case study demonstrates how a scientifically supported and practically applicable nutrition and lifestyle strategy can reduce infection incidence in an illness-prone professional soccer player. In the 3 months before the intervention, the player had 3 upper-respiratory tract infections (URTIs) and subsequently missed 3 competitive matches and 2 weeks' training. He routinely commenced morning training sessions in the fasted state and was estimated to be in a large daily energy deficit. Throughout the 12-week intervention, the amount, composition, and timing of energy intake was altered, quercetin and vitamin D were supplemented, and the player was provided with a daily sleep and hygiene protocol. There was a positive increase in serum vitamin D 25(OH) concentration from baseline to Week 12 (53 n·mol-1 to 120 n·mol-1) and salivary immunoglobulin-A (98 mg·dl-1 to 135 mg·dl-1), as well as a decline in the number of URTI symptoms (1.8 ± 2.0 vs. 0.25 ± 0.5 for Weeks 0-4 and Weeks 8-12, respectively). More important, he maintained availability for all training and matches over the 12-week period. We offer this case study as a real-world applied example for other players and practitioners seeking to deploy nutrition and lifestyle strategies to reduce risk of illness and maximize player availability.

    Full Text Available Relying solely on measures of intellectual aptitude and academic performance in university admissions can be disadvantageous to underprivileged students. The Fiji School of Medicine primarily uses such measures to evaluate and select student applicants, and the introduction of supplementary assessments could provide better access for students from disadvantaged backgrounds. This study examined the need for supplementary assessments in the admission process, types of additional assessments needed, and stakeholders??views on a multi-entry multi-exit strategy currently in use at the Fiji School of Medicine. A survey of the key stakeholders was conducted in February and March 2012 using closed and open ended questionnaire. One hundred and twenty-two validated questionnaires were self-administered by key stakeholders from the College of Medicine, Nursing and Health Sciences (CMNHS and Fiji Ministries of Education and Health, with a response rate of 61%. Returned questionnaires were analysed quantitatively and qualitatively. Sixty-five percent of respondents supported the introduction of supplementary assessments, 49% favoured admissions test, and 16% preferred assessing non-academic factors. Many respondents supported the School?占퐏 multi-entry multi-exit strategy as a ?占퐂ood policy??that provided ?占퐀lexibility??and opportunity for students, but should be better regulated. These findings demonstrate the need for supplementary assessments in the selection process and for continued support for the use of multi-entry multi-exit strategy at the school.

    1995-07-01

    To achieve whole core calculations of the neutron transport equation, we have to follow this 2 step method: space and energy homogenization of the assemblies; resolution of the homogenized equation on the whole core. However, this is no more valid when accidents occur (for instance depressurization causing locally strong heterogeneous media). One solution consists then in coupling two kinds of resolutions: a fine computation on the damaged cell (fine mesh, high number of energy groups) coupled with a coarse one everywhere else. We only deal here with steady state solutions (which already live in 6D spaces). We present here two such methods: The coupling by transmission of homogenized sections and the coupling by transmission of boundary conditions. To understand what this coupling is, we first restrict ourselves to 1D with respect to space in one energy group. The first two chapters deal with a recall of basic properties of the neutron transport equation. We give at chapter 3 some indications of the behaviour of the flux with respect to the cross sections. We present at chapter 4 some couplings and give some properties. Chapter 5 is devoted to a presentation of some numerical applications. (author). 9 refs., 7 figs.

    The curing epoxy resins are widely used in various fields of chemical industry, such as adhesives, automotive, coatings, etc. The process operation consisting of flow and mixing of epoxy resins become difficult due to their high viscosity. One solution is to dissolve the epoxy resin in volatile organic solvents (VOS) such as toluene, xylene or benzene. However, the use of VOS is not only expensive but harmful to the environment.

    Description of complex systems by Density functional theory is treated in this thesis. First, the Density functional theory and a few functionals used to simulate cristals are presented. Specifically, the LDA and GGA functionnals are described and their limits are exposed. Furthermore, the Hubbard model as well as the LDA+U functionnal are addressed in this chapter. These methods enable the study of highly correlated materials. Then, results obtained on polymers are summarized in two articles. The first one treats the band gap variation of ladder-type polymers compared to non ladder type ones. The second article considers small band gap polymers. In this case, it will be shown that an hybrid functional, which contains exact exchange, is required to describe the electronic properties of the polymers under study. Finally, the last chapter address the study of cuprates superconductors. The LDA+U can account for the localization of electrons in copper orbitals. Consequently, a study of the impact of this functionnal on electronic properties of cuprates is conducted. The chapter is ended by an article treating magnetic orders in doped La 2CuO4. Supplementary materials of the second article and a description of the theory of superconductivity of Bardeen, Cooper and Schrieffer are put in annex. Keywords : Electronic correlation, DFT, LDA+U, cuprates, polymers, magnetic orders

    Nuclear science and technology is one of the greatest scientific and technological achievements of mankind in the 20th century. Nuclear science and technology is widely applied in various sectors with over 50 years of development, such as energy, industry, agriculture, health, and environment protection, and is playing an important role in prospering economy, improving people's livelihood, and promoting sustainable development. With global economic development and rising energy consumption, supply of traditional energy source is becoming more stretched and climate change is becoming an increasingly severe challenge. It is a common task of the international community to develop and utilize clean and renewable energy sources and properly address growing contradiction among economic development, energy development and environment protection. Given its advantage as clean, safe and could be applied in large scale, more and more countries are placing importance on nuclear energy. Accelerating peaceful uses of nuclear energy is the common wishes and inevitable choice of many countries. China started the development of nuclear energy in the early 1950s, and with the efforts of over half a century, China has established a relatively complete nuclear industry system. The installed capacity of nuclear power reached 9100 MWe, and nuclear power generation accounts for 2% of the national total electricity generated. Nuclear energy is playing an incremental role for China's economic development. However, nuclear energy utilization is rather insufficient in China, its development level is behind countries which are advanced in nuclear energy use such as the United States and France, the rate of nuclear power generation in the total electricity generated still falls behind the world average level. China's energy supply mix is featured by coal dominant and low proportion of clean energy. To achieve sustainable energy and socio-economic development, China has formulated the energy development strategy of active promoting energy conservation and optimizing energy. structure. Accelerating nuclear power development and enhancing the ratio of clean energy such as nuclear power in the aggregate energy supply is the priority of China's energy development strategy. Currently, peaceful use of nuclear energy has entered a stage of rapid development. A batch of new nuclear power projects are starting construction in coastal areas, and preparation for other new projects is going on in orderly manner, demonstration projects of the introduction of third generation nuclear power technology are moving on smoothly. Scientific and research engineering programs such as China experimental fast reactor, high temperature gas-cooled reactor, and thermal nuclear fusion device are in positive progress. Nuclear fuel cycle industry continues its development and the ability of assured supply of nuclear fuel is being enhanced. China has always attached great importance to nuclear safety in its promotion of nuclear energy utilization, and established a fairly complete nuclear safety legal, regulatory and emergency management system which is in line with international best practices. China has issued series of instruments such as nuclear safety regulations, rules, guidelines, standards. Independent, strict, and efficient nuclear safety supervision and management and scientific management of nuclear facility operators have been put in place to ensure safe and secure operation of nuclear facilities. All these efforts have led to sound nuclear safety record and boosted public confidence in nuclear energy

    Granite and gneiss sampled from the submarine fault scarps of the Sardinia Channel were dated using the apatite fission-track method. One sample provides an age of 22.8 {+-} 1.3 Ma, which is in the range of the cooling ages of the Calabrian-Peloritan basement, where cooling is due to erosion. Three other samples have ages around 10 Ma, probably due to a tectonic denudation during the Tortonian extension in the Sardinia Channel. (authors)

    Proton beam therapy uses positively charged particles, protons, whose physical properties improve dose-distribution (Bragg peak characterized by a sharp distal and lateral penumbra) compared with conventional photon-based radiation therapy (X-ray). These ballistic advantages apply to the treatment of deep-sited tumours located close to critical structures and requiring high-dose levels. [60-250 MeV] proton-beam therapy is now widely accepted as the 'gold standard' in specific indications in adults - ocular melanoma, chordoma and chondrosarcoma of the base of skull - and is regarded as a highly promising treatment modality in the treatment of paediatric malignancies (brain tumours, sarcomas..). This includes the relative sparing of surrounding normal organs from low and mid-doses that can cause deleterious side-effects such as radiation-induced secondary malignancies. Other clinical studies are currently testing proton beam in dose-escalation evaluations, in prostate, lung, hepatocellular cancers, etc. Clinical validation of these new indications appears necessary. To date, over 60, 000 patients worldwide have received part or all of their radiation therapy program by proton beams, in approximately 30 treatment facilities. (authors)

    Delhi is the second largest city of the world both in terms of population and area, as well as being the capital of India. Every year, thousands of people from different states throng to the capital in search of a job in order to earn a living. When these people die and their bodies are found without any identifying documentation, it is very difficult for the police to establish their identities. These bodies are labelled as unidentified/unclaimed or unknown, and are sent for usually sent for medicolegal autopsy. Invariably, skeletonised bodies are also recovered, which are also subjected to medicolegal autopsy. Female foeticide is another social problem, and whenever such foetuses are disposed of illegally, they are also grouped under this category and brought for medicolegal autopsy. We undertook a five-year retrospective analysis (for the period 2010-2014) of all such cases brought for medicolegal autopsy at our centre, which caters only for the south and south-east districts of Delhi. A total of 7964 cases were brought for medicolegal autopsy, of which unknown cases accounted for about 16%. About 25-30 foetuses and skeletonised bodies were brought each year that was studied. The manner of death was certified as natural in about 71% of cases, with predominant pathology in the lungs. There was a clear predominance of males over females, with the 31- to 50-year age group accounting for half of all cases. There was an increase in the number of deaths during months of extreme temperatures. The average time between the recovery of a body by the police and the post-mortem was about seven days. These findings raise many questions, including the failure of governmental policies, police investigating agencies and social menace. The creation of a national missing-persons database as well as a DNA databank is needed to aid in the identification of unidentified/unclaimed and unknown bodies.

    1999-12-31

    This report from the French Deputy of the Meuse region aims at taking stock of four main questions raised by the future organization of the French electric power industry in the context of the opening of the European power market: the public utility of electric power, the future missions of Electricite de france (EdF) company, the questions in relation with the personnel status in the electric power industry, and the status of the regulating authority. In order to give some elements of answer to these questions, the report has been divided into 2 parts: part 1 presents the power production, transport and distribution in the future electric power regulation (the renewal of nuclear facilities, the building of non-nuclear units, the exploitation of the power distribution network, the accounting dissociation and the transparency of accountancy, the organization of network access, the eligible clients, the direct power lines, the obligations of purchase, the distribution and the role of local authorities). Part 2 presents the four main stakes of the modernization of the French electric power sector: the electric power public utility (public concern and rights, government policy, sustain of innovation, environment protection and energy mastery, the transportation and distribution networks, the role of operators and the financing), the future evolution of EdF (missions and organization, future of the public company), the social modernization of the electric power sector (present day status, adaptation, evolution, pensions), the organization and role of the future regulation authority. The propositions of the author are reported in the appendix. (J.S.)

    This report addressed to the prime minister deals with the main four issues relating to the problem of revamping the French electricity sector. These are featured as: 1. The public electricity supply; 2. The future development of 'Electricite de France'; 3. The social renovation of the electricity sector; 4. Management and the role of policy. In turn these four chapters are detailed. Thus the first one addresses the problems: 1. Customizing the general interest supply; 2. Electricity general supply and the state policy; 3. Sustaining innovation, environmental protection and energy management; 4. The transport and distribution grid, the resistance structure of the public supply. Also, this chapter describes the role of the operators in the public electricity supply and tackles the problem of financing the commitments of the public supply. The second chapter sketches the tasks and management of EDF, considers establishing an agency to ensure accounting transparency, discusses the major significance of local collectivities and personnel. The third chapter addresses the following issues: 1. The range of application of the statute of electric and gas industries; 2. Adaptation of the statute; 3. Development of the statute; 4. Pensioners. The forth chapter deals with the definition of regulation, i.e. the management of the network authority and makes proposals for constituting relating commissions. In conclusion, the author pleads for maintaining and developing a major national operator ensuring public supply requirements as well as promotion of French electricity industry. The proposals made by the report's author concerning the operational ways of renewing the nuclear sector, the management of grid of electric transport, the role of local collectivities, creation of a professional trade, the founding regulation commissions and others are thought to prepare France to cope efficiently to the international competition in the years to come. The report is completed by two appendices containing the proposals of the author and a list of the persons interviewed during the mission.

    This work is a contribution to the study of the formation and decay of excited nuclei produced in heavy ion collisions at intermediate energies. The experiments have been carried out at GANIL (Caen, France) with the 4{pi} => 4{pi} multidetector INDRA. This is a detector of charged particles and fragments with a high granularity, an excellent space coverage, low detection thresholds, and a large dynamic range in charge and in energy. The calibration of the Silicon detectors have been performed with light particles and heavy projectiles. Usual methods which calculate the pulse height defect are criticized and a new method is proposed. We also give experimental results about the charge carriers collection in partially depleted detectors. Data analysis needs a comparison between experimental results and phenomenological codes. We describe in chapter III the physical ingredients contained in two of this codes. In the last part, we show the first experimental results obtained with the Xe + Sn system, between 25 MeV/u and 50 MeV/u. Studies on fragment multiplicity distributions show that physical mechanisms with product this fragments are different from those observed at low bombarding energies. (author). 60 refs.

    Full Text Available Backchannel technology can be used to allow students in large lecture courses to communicate with each other and the instructor during the delivery of lecture content and class discussions. It can also be utilized by instructors to capture, summarize, and integrate student questions, ideas, and needs into course content both immediately and throughout the course. The authors integrated backchannel software in one of two sections of a course, leaving the other section as a control; combined, the two sections contained a total number of 871 students. Data was gathered comparing both groups using online surveys and semester grades; results showed that the section using backchannel software had higher class satisfaction and perception of engagement, used their mobile devices more for accessing class content, felt more comfortable participating in class discussions, and had a higher grade average than the section that did not. The authors also explore their own experiences of finding, integrating, and maintaining backchannel technology. La technologie d’arrière-plan peut permettre aux étudiants de grands cours magistraux de communiquer les uns avec les autres et avec l’instructeur durant le cours et les discussions en classe. Les instructeurs peuvent aussi l’utiliser pour saisir, résumer et intégrer les questions, idées et besoins des étudiants dans le contenu du cours, et ce, immédiatement et pendant toute la durée du cours. Les auteurs ont intégré un logiciel d’arrière-plan dans l’une des deux sections d’un cours, faisant de l’autre section son groupe témoin. Ensemble, les deux sections comprenaient 871 étudiants. Des données ont été recueillies pour comparer les deux groupes à l’aide de sondages en ligne et des notes du trimestre. Les résultats ont démontré que la section utilisant le logiciel d’arrière-plan avait une plus grande satisfaction et une meilleure perception de l’engagement, que ses étudiants se servaient de leurs appareils mobiles pour accéder à davantage de contenus, se sentaient plus à l’aise de prendre part aux discussions en classe et avaient une moyenne plus élevée que ceux du groupe qui n’avait pas accès au logiciel. Les auteurs explorent également leurs propres expériences pour trouver, intégrer et entretenir la technologie d’arrière-plan.

    The functioning of a positive electrode in a lithium battery is based on the reversible intercalation of lithium. In some cases, such a reaction can lead to important structural modifications and therefore to an amorphization of the material.

    The functioning of a positive electrode in a lithium battery is based on the reversible intercalation of lithium. In some cases, such a reaction can lead to important structural modifications and therefore to an amorphization of the material. A theoretical approach is presented here that leads to structural predictions and simulations of electrochemical behaviour of positive electrode materials. In the first part, DFT (Density Functional Theory) formalisms and the respective advantages of FLAPW (Full potential Linearized Augmented Plane Waves) and PP/PW (Pseudopotential / Plane Waves) methods are discussed. In the second part are given some fundamental electrochemistry considerations related to the intercalation process, thermodynamics aspects and relationships with electronic structure.

  5. Evolution de certains composés volatils du bois de chêne au cours de son séchage premiers résultats

    Directory of Open Access Journals (Sweden)

    1994-12-01

    Full Text Available Pendant le séchage des merrains sur parc à l'air libre, on assiste à une profonde modification de la composition chimique et du profil aromatique du bois de chêne. La teneur en eugénol, en aldéhydes phénols et en Β-méthyl-y-octalactone augmente régulièrement pendant le vieillissement du bois. Principalement sous forme trans au début du séchage, la Β-méthyl-y-octalactone s'accumule finalement sous la forme cis plus aromatique. Dans le même temps, on observe également une accumulation importante du précurseur inodore de Β-méthyl-y-octalactone. L'intervention des micro-organismes fréquemment isolés sur le bois en cours de séchage naturel sur la formation de composés aromatiques a été étudiée. La culture de diverses moisissures isolées de bois en cours de séchage naturel sur extraits de bois et directement sur sciure de chêne aboutit dans tous les cas à une forte diminution des teneurs en aldéhydes phénols, notamment de la vanilline. En effet, tous les micro-organismes étudiés (Penicilium sp., Trichoderma sp., Aureobasidium sp. sont incapables de dégrader la lignine car ils ne possèdent pas d'activité ligninase. En revanche, ces champignons possèdent une forte activité oxydo-réductase capable de réduire la vanilline en alcool vanillique inodore. En conséquence, les aldéhydes phénols apparaissant au cours du séchage naturel du merrain ne dérivent pas d'une attaque enzymatique mais plus vraisemblablementde l'acidolyse et de l'oxydation chimique de la lignine du bois. Le stockage du bois à l'air libre en présence d'eau et d'oxygène doit permettre une évolution favorable de son potentiel aromatique tant que la vanilline et la cis Β-méthyly-octalactone s'accumulent.

    Summary Background The prevalence of male obesity is increasing but few men take part in weight loss programmes. We assessed the effect of a weight loss and healthy living programme on weight loss in football (soccer) fans. Methods We did a two-group, pragmatic, randomised controlled trial of 747 male football fans aged 35–65 years with a body-mass index (BMI) of 28 kg/m2 or higher from 13 Scottish professional football clubs. Participants were randomly assigned with SAS (version 9·2, block size 2–9) in a 1:1 ratio, stratified by club, to a weight loss programme delivered by community coaching staff in 12 sessions held every week. The intervention group started a weight loss programme within 3 weeks, and the comparison group were put on a 12 month waiting list. All participants received a weight management booklet. Primary outcome was mean difference in weight loss between groups at 12 months, expressed as absolute weight and a percentage of their baseline weight. Primary outcome assessment was masked. Analyses were based on intention to treat. The trial is registered with Current Controlled Trials, number ISRCTN32677491. Findings 374 men were allocated to the intervention group and 374 to the comparison group. 333 (89%) of the intervention group and 355 (95%) of the comparison group completed 12 month assessments. At 12 months the mean difference in weight loss between groups, adjusted for baseline weight and club, was 4·94 kg (95% CI 3·95–5·94) and percentage weight loss, similarly adjusted, was 4·36% (3·64–5·08), both in favour of the intervention (p<0·0001). Eight serious adverse events were reported, five in the intervention group (lost consciousness due to drugs for pre-existing angina, gallbladder removal, hospital admission with suspected heart attack, ruptured gut, and ruptured Achilles tendon) and three in the comparison group (transient ischaemic attack, and two deaths). Of these, two adverse events were reported as related to participation in the programme (gallbladder removal and ruptured Achilles tendon). Interpretation The FFIT programme can help a large proportion of men to lose a clinically important amount of weight; it offers one effective strategy to challenge male obesity. PMID:24457205

    After about fifteen years of development, the ATLAS detector is ready to operate and recorded, in 2008, several millions of cosmic events as well as first LHC data. This achievement is based on the long experience of beam tests and on the large effort towards the detector in situ commissioning undertaken by the ATLAS collaboration. This promises fast ability to perform searches for evidence of Higgs boson and new physics. I heavily contributed to the in situ commissioning of the EM calorimeter. To verify its performance, I studied the first cosmic data taken in 2006 which allowed the first in situ analysis of dead channels, energy reconstruction and detector response uniformity. This participation to the commissioning has continued with the study of the single beam data recorded during the first week of LHC operation (Sept. 2008). Expanding on my expertise of the EM calorimeter, I focused my physics analysis, prepared with simulation, on the promising discovery potential of new physics at LHC via the di-elect...

    2004-05-15

    This work was dedicated to the search for pairs of first generation scalar leptoquarks one decaying into ej and the other into {nu}j. The experimental data used (175,6 pb{sup -1}) is that collected during the run-II of the D0 experiment at Tevatron. The production cross-sections of scalar leptoquark pairs has been assessed at a 95% confidence level for different values of the mass. The comparison of these values with theoretical values has led us to state that for a branching ratio {beta} = 0.5 the existence of scalar leptoquarks with a mass lower than 194 GeV is not possible. For a branching ratio {beta} = 1, some scalar leptoquarks with mass < 238 GeV may be excluded while for {beta} = 0.5, some scalar leptoquarks with mass < 213 GeV are excluded.

    For 15% of resident households in metropolitan France, the proportion of income going on home and water heating is high, in the sense that it is twice the median housing-expense to income ratio. With this same criterion, the cost of the most mandatory car journeys is high for 10% of households, in relation to their budgets. In all, 22% of households (i.e. 5.9 million) are experiencing energy vulnerability for one or other of the items of consumption, and 3% of households (i.e. 700 000) are vulnerable for both items. The risk of vulnerability varies over national territory, with differences depending on the items of expenditure considered: climate is the primary factor where disparity in housing-related vulnerability is concerned, whereas the predominant factor for travel is distance from urban centres

    Poly(propylene oxide) (PPO), a novel soft elastomeric material, and its composites were investigated as a new dielectric electroactive polymer (EAP). The PPO networks were obtained from thiol-ene chemistry by photochemical crosslinking of α,ω-diallyl PPO with a tetra-functional thiol. The elastomer was reinforced with hexamethylenedisilazane treated fumed silica to improve the mechanical properties of PPO. The mechanical properties of PPO and composites thereof were investigated by shear rheology and stress–strain measurements. It was found that incorporation of silica particles improved the stability of the otherwise mechanically weak pure PPO network. Dielectric spectroscopy revealed high relative dielectric permittivity of PPO at 10 3 Hz of 5.6. The relative permittivity was decreased slightly upon addition of fillers, but remained higher than the commonly used acrylic EAP material VHB4910. The electromechanical actuation performance of both PPO and its composites showed properties as good as VHB4910 and a lower viscous loss. (paper)

    Sayavedra-Soto, L.A.; Montgomery, M.W.

    1986-01-01

    When polyphenoloxidase (PPO) was exposed to sulfite prior to substrate addition, inhibition was irreversible. Trials to regenerate PPO activity, using extensive dialysis, column chromatography, and addition of copper salts were not successful. Increased concentrations of sulfite and pH levels less than 5 enhanced the inhibition of PPO by sulfite. At pH 4, concentrations greater than 0.04 mg/mL completely inhibited 1000 units of PPO activity almost instantaneously. This suggested that the HSO 3 - molecule was the main component in the sulfite system inhibiting PPO. Column chromatography, extensive dialysis, and gel electrophoresis did not demonstrate 35 SO 2 bound to purified pear PPO protein. Formation of extra protein bands of sulfite inhibited purified pear PPO fractions on gel electrophoresis was demonstrated. This and other evidence suggested that the major mode of direct irreversible inhibition of PPO was modification of the protein structure, with retention of its molecular unity

    Full Text Available Abstract Background Polyphenol oxidase (PPO activity in plants is a trait with potential economic, agricultural and environmental impact. In relation to the food industry, PPO-induced browning causes unacceptable discolouration in fruit and vegetables: from an agriculture perspective, PPO can protect plants against pathogens and environmental stress, improve ruminant growth by increasing nitrogen absorption and decreasing nitrogen loss to the environment through the animal's urine. The high PPO legume, red clover, has a significant economic and environmental role in sustaining low-input organic and conventional farms. Molecular markers for a range of important agricultural traits are being developed for red clover and improved knowledge of PPO genes and their structure will facilitate molecular breeding. Results A bacterial artificial chromosome (BAC library comprising 26,016 BAC clones with an average 135 Kb insert size, was constructed from Trifolium pratense L. (red clover, a diploid legume with a haploid genome size of 440–637 Mb. Library coverage of 6–8 genome equivalents ensured good representation of genes: the library was screened for polyphenol oxidase (PPO genes. Two single copy PPO genes, PPO4 and PPO5, were identified to add to a family of three, previously reported, paralogous genes (PPO1–PPO3. Multiple PPO1 copies were identified and characterised revealing a subfamily comprising three variants PPO1/2, PPO1/4 and PPO1/5. Six PPO genes clustered within the genome: four separate BAC clones could be assembled onto a predicted 190–510 Kb single BAC contig. Conclusion A PPO gene family in red clover resides as a cluster of at least 6 genes. Three of these genes have high homology, suggesting a more recent evolutionary event. This PPO cluster covers a longer region of the genome than clusters detected in rice or previously reported in tomato. Full-length coding sequences from PPO4, PPO5, PPO1/5 and PPO1/4 will facilitate

    Full Text Available Explant browning is one of the major problems in the tissue culture process, and polyphenol oxidase (PPO, is the major proteases involved in plant tissue browning. We investigated the effects of polyphenol oxidase on the early stage of browning in explants of the orchid Phalaenopsis. Our results show that PPO activity was significantly higher in explants cultured for 3 d than in the 0 h control. The levels of PPO transcripts and PPO protein were significantly higher in explants cultured for 6 h compared to the 0 h control; these high expression levels were maintained over increasing cultivation time. Cycloheximide (CHX treatment reduced PPO transcript levels, PPO protein levels, and PPO enzyme activity. High levels of PPO mRNA and PPO protein were detected in the cytoplasm and vascular bundles of Phalaenopsis explants cultured for 6 h compared to explants cultured for 0 h, 24 h, and 3 d. CHX treatment did not significantly affect the distribution of PPO mRNA and PPO protein in explant tissues, but their levels were significantly lower than those of the untreated control.

    Browning of plant tissue is generally considered attributable to enzymatic oxidation by polyphenol oxidase (PPO). Electrophoresis followed by activity staining has been used as an effective procedure to visually detect and isolate isozymes; however, it has not been applied for examination of various PPO isozymes in lettuce. Our study demonstrated that different lettuce PPO isozymes could be detected at different pH in active staining, and multiple isozymes were detected only under alkaline conditions. As a result, we concluded that activity staining with approximately pH 8 enabled to detect various PPO isozymes in lettuce. By expression analysis of the PPO isozymes after wounding, PPO isozymes that correlated with time-course of tissue browning were detected. The wound-induced PPO may play a key role in enzymatic browning.

    Poly(propylene oxide) (PPO), a novel soft elastomeric material, and its composites were investigated as a new dielectric electroactive polymer (EAP). The PPO networks were obtained from thiol-ene chemistry by photochemical crosslinking of ,!-diallyl PPO with a tetra-functional thiol. The elastomer...... was reinforced with hexamethylenedisilazane treated fumed silica to improve the mechanical properties of PPO. The mechanical properties of PPO and composites thereof were investigated by shear rheology and stress–strain measurements. It was found that incorporation of silica particles improved the stability...... of the otherwise mechanically weak pure PPO network. Dielectric spectroscopy revealed high relative dielectric permittivity of PPO at 103 Hz of 5.6. The relative permittivity was decreased slightly upon addition of fillers, but remained higher than the commonly used acrylic EAP material VHB4910...

    Pineapple internal browning (IB) is a chilling injury that produces enzymatic browning associated with flesh translucency. Pineapple biodiversity allowed the investigation of how polyphenol oxidase (PPO) and peroxidase (POD) activities with their different isoforms are involved in the IB mechanism. Fruits of four varieties that expressed IB symptoms differently, Smooth Cayenne (SCay) and the hybrids MD2, Flhoran 41 (Flh 41), and Flhoran 53 (Flh 53), were stressed by cold. The susceptible varieties showed classical brown spots but different patterns of IB, whereas MD2 and controls showed no IB. Enzymatic activities were measured on fruit protein extracts and PPO and POD isoforms separated on mini-gels (PhastSystem). Only PPO activity was significantly enhanced in the presence of IB. Up to six PPO isoforms were identified in the susceptible varieties. PPO was barely detectable in the nonsusceptible variety MD2 and in controls. The number of PPO isoforms and the total PPO activity after chilling are varietal characteristics.

    Full Text Available Polyphenol oxidases (PPOs catalyze the oxidation of phenolics to quinones, the secondary reactions of which lead to oxidative browning and postharvest losses of many fruits and vegetables. PPOs are ubiquitous in angiosperms, are inducible by both biotic and abiotic stresses, and have been implicated in several physiological processes including plant defense against pathogens and insects, the Mehler reaction, photoreduction of molecular oxygen by PSI, regulation of plastidic oxygen levels, aurone biosynthesis and the phenylpropanoid pathway. Here we review experiments in which the roles of PPO in disease and insect resistance as well as in the Mehler reaction were investigated using transgenic tomato (Lycopersicon esculentum plants with modified PPO expression levels (suppressed PPO and overexpressing PPO. These transgenic plants showed normal growth, development and reproduction under laboratory, growth chamber and greenhouse conditions. Antisense PPO expression dramatically increased susceptibility while PPO overexpression increased resistance of tomato plants to Pseudomonas syringae. Similarly, PPO-overexpressing transgenic plants showed an increase in resistance to various insects, including common cutworm (Spodoptera litura (F., cotton bollworm (Helicoverpa armigera (Hübner and beet army worm (Spodoptera exigua (Hübner, whereas larvae feeding on plants with suppressed PPO activity had higher larval growth rates and consumed more foliage. Similar increases in weight gain, foliage consumption, and survival were also observed with Colorado potato beetles (Leptinotarsa decemlineata (Say feeding on antisense PPO transgenic tomatoes. The putative defensive mechanisms conferred by PPO and its interaction with other defense proteins are discussed. In addition, transgenic plants with suppressed PPO exhibited more favorable water relations and decreased photoinhibition compared to nontransformed controls and transgenic plants

    Polyphenol oxidase (PPO) and, to a minor extent, peroxidase (POD) represent the key enzymes involved in enzymatic browning, a negative process induced by cutting fresh-cut produce such as lettuce (Lactuca sativa) and rocket salad (Eruca sativa). Although ascorbic acid is frequently utilised as an anti-browning agent, its mechanism in the prevention of the browning phenomenon is not clearly understood. The activity of PPO and POD and their isoforms in lettuce (a high-browning and low-ascorbic acid species) and rocket salad (a low-browning and high-ascorbic species) was characterised. The kinetic parameters of PPO and in vitro ascorbic acid-PPO inhibition were also investigated. In rocket salad, PPO activity was much lower than that in lettuce and cutting induced an increase in PPO activity only in lettuce. Exogenous ascorbic acid (5 mmol L(-1)) reduced PPO activity by about 90% in lettuce. POD did not appear to be closely related to browning in lettuce. PPO is the main enzyme involved in the browning phenomenon; POD appears to play a minor role. The concentration of endogenous ascorbic acid in rocket salad was related to its low-browning sensitivity after cutting. In lettuce, the addition of ascorbic acid directly inhibited PPO activity. The results suggest that the high ascorbic acid content found in rocket salad plays an effective role in reducing PPO activity. © 2012 Society of Chemical Industry.

    Full Text Available Phenolic compounds, such as catechol, are released into the environment from a variety of industrial sources and they present a serious ecosystem burden. This work examined the possibility of using partially purified apple polyphenol oxidase (PPO for bioremediation of phenolic contaminants. In order to optimize process conditions, the optimal pH and temperature for PPO activity were determined, while PPO affinity toward various phenols, as well as the effect of some salts and organic solvents which can be found in wastewaters, was used to confirm applicability of PPO in wastewater treatment. It was found that partially purified apple PPO shows maximal activity at pH 6.8 and 25 °C, but exhibits more than 85 % of its maximal activity in pH range from 5 to 8, and more than 90 % of activity in temperature range from 10 to 50 °C. PPO showed high affinity for various diphenols, but lack of affinity toward monophenols. Sodium tetraborate decahydrate moderately inhibited PPO activity, while exposure of PPO to the presence of organic solvents (φ = 5 % caused 40 % loss in its activity. Catechol oxidation by PPO performed for just 5 min in a batch reactor at optimal process conditions resulted in 25 % conversion. Based on obtained data, it seems that partially purified apple PPO has reasonable potential in wastewater treatment.

    In the Tokamak TORE-SUPRA, the plasma facing components absorbs and evacuate (active cooling) high power fluxes (up to 10 MW/m{sup 2}). Their thermal behavior study is essential for the success of controlled thermonuclear fusion line. The first part is devoted to the study of power deposition on the TORE-SUPRA actively cooled limiters. A model of power deposition on one of the limiters is developed. It takes into account the magnetic topology and a description of the plasma edge. The model is validated with experimental calorimetric data obtained during a series of shots. This will allow to compare the surface temperature measurements with the predicted ones. The main purpose of this thesis was to evaluate and develop a new temperature measurement system. It works in the near infrared range (890 nm) and is designed to complete the existing thermographic diagnostic of TORE-SUPRA. By using the radiation laws (for a blackbody and the plasma) and the laboratory calibration one can estimate the surface temperature of the observed object. We evaluate the performances and limits of such a device in the harsh conditions encountered in a Tokamak environment. On the one hand, in a quasi ideal situation, this analysis shows that the range of measurements is 600 deg. C to 2500 deg. C. On the other hand, when one takes into account of the plasma radiation (with an averaged central plasma density of 6.10{sup 19} m{sup -3}), we find that the minimum surface temperature rise to 900 deg. C instead of 700 deg. C. In the near future, according to the development of IR-CCD cameras working in the near infrared range up to 2 micrometers, we will be able to keep the good spatial resolution with an improved lower limit for the temperature down to 150 deg. C. The last section deals with a number of computer tools to process the images obtained from experiments on TORE-SUPRA. A pattern recognition application was developed to detect a complex plasma iso-intensity structure. 87 refs.

    Steam Generator tubes (alloys 600, 690 and 800) are protected against corrosion by an oxide layer. The release of corrosion products into the primary water of the Pressurised Water Reactor is limited by this layer. Activation of these products increases the radioactivity. Breakdown of the passive film can lead to Stress Corrosion Cracking (SCC). The aim of this study is to understand the early stages of passivation of these alloys, in high temperature and high pressure water. A new micro-autoclave was developed to achieve short time exposures (from several seconds to 10 minutes). The surfaces were characterised by XPS, NRA, STM and SEM and a kinetic model is proposed for the alloy 600. Longer oxidation times were studied (up to 400 hours). The kinetics obtained for short time oxidations were used to fit the long oxidation time behaviour. This reveals that the initial stages of oxidation are essential in the passive films growth in such conditions. (author)

    Climatic concerns become more substantial each day. Proofs of climatic change of man-made origin accumulate. Even if the consequences of such change remain difficult to foresee for most, this major environmental problem is now the subject of great attention by governments and public opinion. In this context, biofuels have known a growing interest over the last years. This enthusiasm is essentially based on their potential to reduce non-renewable energy consumption, notably petroleum, and to reduce greenhouse gas emissions (GHG) for the transportation sector. Indeed, the transportation sector currently generates about 14% of the world's GHG at a growth rate of about 2% per year that is particularly difficult to reduce. The issue of biofuel balances on these two criteria (GHG emission and non-renewable energy consumption) is therefore fundamental because it justifies largely the different forms of public financial support devoted to ensure the development of these pathways. Thus, numerous studies are aimed at comparing biofuels to equivalent petroleum fuels (gasoline and diesel) in order to assess GHG emission reduction potential associated with using biofuels in transportation. The Directive 2009/28/CE of April 29, 2009 dedicated to Renewable Energies promotion (RE Directive) sets forth a compelling objective, asking each Member State to make sure that the portion of energy produced from renewable sources in all forms of transportation will be at least equal to 10% of its final energy consumption in the transportation sector by 2020. This objective is set subject to a production of sustainable nature and to second generation biofuel availability on the market. The RE Directive introduces several criteria for qualifying biofuels' sustainability. Thus, biofuels should not be produced from land recognized as of great value in terms of biological diversity: forest undisturbed by important human activity, zone assigned to nature conservation, meadows presenting a great value with regards to biodiversity. They should not be produced from lands presenting an important stock of carbon, i.e. wetlands (lands covered or saturated with water permanently or during the greatest part of the year, such as virgin peat-bogs) or continuous forest zones (of more than 1 hectare, characterized by a tree population with height above 5 meters and foliage covering more than 30% of its surface). Among these criteria, there is a significant one regarding greenhouse gas emissions. For a biofuel to participate in the reduction goal, the pathway concerned will need to show that the biofuel produced enables to reduce greenhouse gas emission by at least 35% in relation to fossil equivalents. This gain would even reach a minimum of 50% in the beginning of 2017. The determination of this gain requires to conduct a life cycle assessment of the produced biofuel. Even if the RE Directive provides elements for calculating biofuel environmental balance in its Appendix V, such study remains complex and requires calculation assumptions which could influence the result in a non negligible way. The existence of indirect effects on the markets adds to this complexity. Such difficulties fuel critiques and the diffusion of contradictory messages on whether these pathways are beneficial or not. In this context and avoiding reefs and critiques of the assembled calculation methodologies, the French Administration first wished to have a methodological benchmark for analyzing the impact of biofuel pathways on greenhouse gas and the energy consumptions linked to such pathways for France. The challenge resided in elaborating a real methodological engineering work aiming at obtaining a common benchmark shared by all parties concerned. This consensus work was conducted in 2007-2008 and resulted in the writing of a guide defining recommendations for completing biofuel LCA. This work, conducted at the French level and in parallel with the European Directive, led to the construction of a national calculation method parallel to that defined by the Commission. This work presents here a global consistency with the Directive, namely in term of allocation principle based on energy pro-rata, but was also performed in a finer, step by step detail level. The objective of the study is to realize the life cycle assessment of the current biofuel pathways (also called 'first generation') by applying the principles retained in the 2008 methodological guide. This work was performed with the technical support of industrial actors, technical institutes, research centers, and environmental associations. Integrating the European context and wishing to put the results in perspective, this study performs, in a second step, an analysis of the results obtained with other methodologies, including those from the Directive. This critical and constructive aspect emphasizes points of vigilance to keep in mind in the European discussions with regards to quantify biofuel sustainability

    La révolution belge de 1830 ne fut pas préméditée. L’opposition au gouvernement, de 1828 à 1830, reste dans les bornes de la légalité. L’Union des catholiques et des libéraux réalisée depuis 1828 a organisé le pétitionnement : elle réclamait les libertés de presse et d’enseignement, l’application loyale de la Constitution. Mais nulle part n’apparaît, le désir d’un bouleversement. La lutte contre les empiétements du pouvoir est menée par des parlementaires et dans le cadre des institutions exi...

    Experiments have been performed in a cylindrical smooth Inconel tube: 3 mm ID, 3.5 mm OD, electrically heated (50 Hz) along 300 mm length. Pressure varied from 5 to 100 bars (P{sub c} = 113 bars) mass velocity from 40 to 500 g/cm{sup 2}. s, inlet temperature from - 33 deg C to 95 deg C, heat fluxes to 315 W/cm{sup 2}, maximum wall temperatures 850 deg C, quality 0 to 0.80. The correlation Nu = CRe{sup 0.8} Pr{sup 0.4} is found available for homogeneous liquid-phase heat transfer coefficients with C = 0.021. Influences of P, G, t{sub e} and x on critical heat fluxes is discussed. A correlation of the type q{sub c} = A(P)G{sup m} {delta}t{sub sub}{sup n} (Jens and Lottes) is chosen for the negative qualities and for positive qualities we propose q{sub c} = B(P)/G{sup b(P)} x (1000/H{sub c}){sup 2.5}. Two-phase pressure drops can be calculated by Martinelli-Nelson method with a good approximation. Experimental results are presented in tables (burn-out) and measured temperatures profiles are separately published.

    An examination of the mechanical effects produced on rocks by an underground nuclear explosion calls for the use of particular means of exploration which are described in this report, special attention being paid to the equipment used in connection with the French nuclear tests in the Sahara. The drilling methods used (rotary and turbo-drilling) are adapted to the particular conditions of the sampling programme, to the radioactivity and to the temperature in the region of the explosion. A study of the samples makes it possible to obtain the new characteristics of the rock and to assess the chemical and mechanical transformations which it has undergone. An examination of the core obtained from the drilling, together with a knowledge of the drilling parameters (depth of the probe, sample recovery, etc...), makes it possible to study the extent and the characteristics of the zones which have been damaged to different degrees according to their distance from the zero point: cavity, strongly powdered zone, fractured zone, chimney, zones containing high stresses leading to a particular type of fracture of the cores. The problems connected with the interpretation of the results are also presented. (author) [French] L'examen des effets mecaniques provoques par une explosion nucleaire souterraine sur la roche necessite la mise en oeuvre de moyens d'exploration particuliers dont l'expose fait l'objet de ce rapport, essentiellement pour les moyens utilises autour des essais nucleaires francais au Sahara. Les methodes de forage (rotary et turboforage) sont adaptees aux conditions particulieres dues au programme d'echantillonnage, a la radioactivite et a la temperature regnant a proximite du point de tir. L'etude des echantillons permet la determination des nouveaux caracteres de la roche et de ses transformations chimique et mecanique. L'examen des carottes et l'utilisation des parametres de forage (cotes sondeurs, recuperation des echantillons, etc...) permettent d'etudier l'extension et les caracteristiques des zones ayant subi des degats differents suivant leur distance au point zero: cavite, zone intensement broyee, zone fracturee, cheminee, zone dans laquelle regnent des contraintes elevees provoquant une fracturation particuliere des carottes. Les problemes lies a l'interpretation des resultats ont ete egalement exposes. (auteur)

    Full Text Available The long-standing, more mythical than fact-based assumptions about ancient trade contacts between West Africa and the wider world prior to the Arab conquest of North Africa have only been substantiated by archaeological evidence in recent years. Although the number of imported items known to have been brought into West Africa during late Roman and Byzantine times just started growing, the mechanisms of their diffusion are still far from being understood. This can mainly be set down to the dearth of convincing material evidence from other archaeological sites in West Africa, the Sahara and North Africa — the result of a lack of research and, perhaps too, of trade in “invisible” merchandise Previous archeological studies on this topic are discussed; and the preliminary findings of recent research in the eastern Niger Bend, presented.Les présupposés de longue date – plutôt mythiques que fondés sur des faits – à propos du commerce entre l’Afrique occidentale et le reste du monde avant la conquête arabe de l’Afrique du Nord n’ont été que récemment étayés par des travaux archéologiques. Bien que les découvertes d'articles importés, connus pour avoir été acheminés en Afrique de l'Ouest pendant les périodes romaine tardive et byzantine, sont, depuis peu, de plus en plus nombreuses, nous ne comprenons pas toujours les mécanismes de diffusion de ces derniers. Cette incompréhension est avant tout liée au manque d’indices matériels probants provenant d’autres sites archéologiques en Afrique de l’Ouest, au Sahara et en Afrique du Nord. Cela résulte à la fois d’un manque de recherche et, peut-être aussi, du commerce en marchandise “invisible”. Les études archéologiques antérieures sur le sujet sont ici discutées ; et les résultats préliminaires de recherches récentes dans la partie orientale de la boucle du Niger sont présentés.

    The Alice experiment that is dedicated to the study of ultra-relativistic heavy ion collisions, will take place in the future large hadron collider (LHC) at CERN. The dimuon arm spectrometer of the Alice experiment is devoted to the search of a new signature of the existence of the quark gluon plasma (QGP). The first chapter is dedicated to the physics notions linked to the study of QGP, a few signatures are proposed for the detection of QGP, particularly the signature concerning the production rate of quarkonium. The second chapter deals with particle detection involved in Alice experiment, the dimuon arm spectrometer is a detector dedicated to the track reconstruction of muons issued from the decay of heavy mesons from J/{psi} and {upsilon} families. The third and the fourth chapters present the studies made to integrate a reliable model of the dimuon arm in the global simulation code of Alice (Aliroot). The fifth chapter presents the software TB{sup 2} that has been developed within the framework of this thesis in order to check and control the output data when the detector is tested with a real particle beam. The sixth chapter presents the results of the tests that have been performed with a 7 GeV/c pion beam. These tests have shown that the electronic noise is coherent with the specifications of Alice experiment. A factor 1,8 between the highest and the weakest values of the gain has been measured in the chamber. The detection efficiency of the chamber has been estimated to 99% in the different cases studied.

    The authors used gamma cardiology during the abatement of 16 cases of asthma with a view to detecting heart attacks not otherwise visible with routine methods of examination: clinical, radiological and electro-cardio-graphical. In gamma cardiology, a radioactive indicator is used and its path followed in the cavities of the heart. The method makes it possible to study the circulation in the right heart, the pulmonary crossing, and the left heart, as well as evaluation of the heart-flow. As a result of their investigations the authors, after having discussed the significance of the data obtained with the method, suggest that it is possible by the use of gamma cardiography during the abatement of an asthma attack: 1- To confirm attacks of the right heart which have already been detected by ordinary methods. 2- To confirm the presence of modifications in the recorded curves which suggest, in the case of the left heart, possible attack; such on attack is also indicated, in a small number of cases, by electrocardiography curves. Some considerations are put forward by the authors concerning the physiopathology of attacks on the left heart. (authors) [French] Les auteurs ont fait appel a la gammacardiographie au decours de 16 cas d'etat de mal asthmatique, dans le but d'objectiver des atteintes cardiaques incapables d'etre revelees par les moyens d'exploration de routine: cliniques, radiologiques et electrocardiographiques. La gammacardiographie est un procede qui enregistre a l'aide d'un indicateur radioactif, le trajet de celui-ci dans les cavites cardiaques. Elle permet l'etude de la circulation dans le coeur droit, de la traversee pulmonaire, et le coeur gauche, de meme que le calcul du debit cardiaque. Au terme de leurs investigations, les auteurs apres avoir discute la signification des donnees fournies par la methode admettent que la gammacardiographie objective au secours de l'etat de mal asthmatique: 1- La confirmation de l'atteinte du coeur droit deja etablie par les methodes courantes. 2- La presence de modifications des traces enregistres, qui suggerent pour le coeur gauche une atteinte vraisemblable comme l'indiquent dans un petit nombre de cas, les traces electrocardiographiques. Des considerations sur la physiopathologie de l'atteinte du coeur gauche sont formulees par les auteurs. (auteurs)

    Full Text Available Although Gershwin’s Porgy & Bess (1935 is still regarded by most critics as the first African-American opera, Louis Gruenberg’s The Emperor Jones (1933 and Scott Joplin’s Treemonisha (1910 have recently challenged this sacrosanct position. Today, according to some researchers, Frederick Delius’s Koanga, based upon the central episode of the story of “Bras coupé” in George Cable’s The Grandissimes, composed in 1897 but whose première took place in 1904, could claim to be “actually the first”. This statement obviously raises the question of the definition of an “African–American” and the attendant criteria. Through an analysis of the libretto as well as the reviews of the various performances from the late 1890’s to the early 1970’s, this article aims to assess the African-American criteria of Koanga.

    1994-12-01

    Full Text Available Pendant le séchage naturel à l'air libre du bois de chêne, on assiste à une diminution régulière de la teneur du bois en composés extractibles et notamment en composés phénoliques du type ellagitanins. La diminution de la teneur en ellagitanins provient essentiellement de la disparition des formes oligomères solubles dans l'eau; les tanins polymérisés non extractibles car liés aux parois, évoluent peu au çours du séchage naturel à l'air libre. Les bois séchés rapidement à l'étuve possèdent toujours des quantités plus importantes de polyphénols. Dans le même temps et quel que soit le mode de séchage, on obselVe une diminution des coumarines glucosilées et une augmentation non proportionnelle des formes aglycones. D'un point de vue organoleptique, la diminution de l'ensemble des polyphénols pendant le séchage peut être interprétée comme favorable à l'évolution de la qualité du merrain. En effet, les fractions amères et astringentes du bois de chêne correspondent respectivement .sr certains tanins ellagiques et catéchiques. L'intelVention des micro-organismes isolés de bois de chêne en cours de séchage naturel dans la disparition des composés phénoliques du bois est discutée. La grande majorité des moisissures étudiées est capable de dégrader enzymatiquement les tanins hydrolysables du chêne. Cependant, ces mêmes composés s'hydrolysent et s'oxydent spontanément en présence d'eau et d'oxygène. En conséquence, considérant le profil de colonisation du bois par les micro-organismes et celui des composés phénoliques extractibles, on peut supposer que l'on assiste vraisemblablement pendant le séchage naturel du bois à une dégradation biochimique et chimique des polyphénols dans les couches superficielles du merrain (0 à 4 mm de profondeur et à une dégradation presque' exclusivement chimique au coeur du merrain. La présence d'eau et d'oxygène apparaÎt par conséquent comme un facteur important dans l'évolution de la composition du bois pendant son séchage.

    Full Text Available La saga des Péniel met en scène des personnages prisonniers d’un passé douloureux hérité de leurs ancêtres : c’est que la malignité du mal consiste à parasiter la transmission. Seule la révélation de la porosité humaine permet aux personnages d’échapper à cette logique infernale pour convertir leur passivité de légataire en responsabilité de répondant due à autrui et à un Dieu qui s’est dépouillé de ses forces et de son Verbe pour créer le monde. C’est le sens du silence de Dieu – vestige de ce geste de retrait divin – que Sylvie Germain cherche à nous transmettre. The saga of the Péniel family stages characters imprisoned by a distressful past inherited from their ancestors. Transmission, or what fails to be transmitted, is central to understanding the curse of the bloodline. Only the revelation of the porousness of human interaction makes it possible for the characters to escape from this infernal logic and to convert their passivity as legatees into the responsibility of guarantors responding to others as well as to God. It is the significance of the silence of God–vestige of the gesture of divine withdrawal–that Sylvie Germain seeks to transmit to her reader.

Elles correspondent à des structures domestiques (un bâtiment et des fosses et à une entité “ cultuelle ”: un double enclos en “ U ”.L’habitation et ses annexes sont représentées par un bâtiment de plan quadrangulaire sur poteaux et une grande fosse riche en mobilier (céramiques, ossements et silex taillés. Cette structure peut être associée au fonctionnement d’un four de type “ polynésien ” et avoir servi de fosse de rejet.Le double enclos, ouvert vers le nord, est localisé au nord-est du site.Même si trois céramiques entières ont été trouvées dans son fossé externe, l’essentiel du mobilier céramique (177 individus sur 192 est issu de la grande fosse. Il s’agit principalement de coupes, de jattes parfois incisées, de petits gobelets à panse globulaire typiques du Hallstatt C ou de vases servant au stockage. Ils sont dotés de manière régulière de cordons digités.Ce petit établissement du début de l’âge du Fer a livré un bon échantillon des céramiques en usage en Eure-et-Loir à cette époque ainsi que des vestiges archéozoologiques et lithiques en quantité intéressante. Ces découvertes donnent de nouvelles informations sur les affinités culturelles à la transition entre l’âge du Bronze et l’âge du Fer, période peu documentée dans le Nord de la région Centre.The excavation of the site of Ouches at Sours (28 has enabled the updating of an important settlement from the early Neolithic and the discovery, in the northern part of the site, of several structures datable to the beginning of the Iron Age (Hallstatt C. They correspond to domestic structures (a building and some ditches and a “worship” entity: a double enclosure in a “U” shape.The dwelling and its annexes are represented by a quadrangular building on posts and a large ditch which is rich in furnishings (ceramic, bone and worked flint. This structure may be associated to the working of a “Polynesian” type kiln and serve as a reject pit. The double enclosure, open towards the north is situated to the north-east of the site.Even though three entire ceramic vessels have been found in the outer ditch, the majority of the ceramic furnishings (177 out of 192 have come from the large ditch, principally cups, bowls which are sometimes inscribed, small goblets with a globular middle typical of Hallstatt C or vessels used for storing. They regularly have finger made cords.This small dwelling from the beginning of the Iron Age has provided a good sample of ceramics in use in Eure-et-Loir in this period as well as some archaeozoological remains and lithics in interesting quantities. These discoveries provided new information on the cultural affinities to the transition between the Bronze and Iron ages, a period which is little researched in the north of the Centre region.

    Two test tubes were used: Inconel (ID 3 mm, OD 3.5 mn length 300 mm) and tantalum (ID 3 mm, OD 4 mm; length 450 mm). Measurements were performed in the following conditions inlet temperature of subcooled liquid from +4 deg C to + 54 deg C; inlet pressure from 10 to 42, bars; mass velocity from 33 to 243 g/cm{sup 2}.s; maximum heat flux 583 W/cm{sup 2}; maximum wall temperature 1523 deg C; steam quality reaching 1.

    The results of experiments in the light water cooled D{sub 2}O reflected critical assembly ALIZE III have been compared to calculations. A diffusion model was used with 3 fast and epithermal groups and two overlapping thermal groups, which leads to good agreement of calculated and measured power maps, even in the case of strong variations of the neutron spectrum in the core. The difference of calculated and measured k{sub eff} was smaller than 0.5 per cent {delta}k/k. Calculations of void and structure material coefficients of the reactivity of 'black' rods in the reflector, of spectrum variations (Cd-ratio, Pu-U-ratio) and to the delayed photoneutron fraction in the D{sub 2}O reflector were made. Measurements of the influence of beam tubes on reactivity and flux distribution in the reflector were interpreted with regard to an optimum beam tube arrangement for the Franco- German High Flux Reactor. (author) [French] Les resultats des experiences faites dans la maquette critique ALIZE III, refrigeree a l'eau legere et reflechie par l'eau lourde, ont ete compares aux calculs.

Ce modele a permis de calculer la distribution de puissance dans le coeur en bon accord avec les mesures, meme dans le cas d'une forte variation du spectre des neutrons dans le coeur. L'erreur entre k{sub eff} calcule et mesure etait inferieure a 0,5 pour cent {delta}k/k.

    While the oil barrel has exceeded the historical price of 70$, the French government has put forward two exigencies: reducing the weight of the oil bill and reinforcing France's energy independence through the development of nuclear and renewable energies and with the implementation of an energy saving policy, and sharing in an equitable way the petroleum 'weight' taking into account the situation of oil-dependent professionals. In this communication, the prime minister develops the different point of this policy, in particular the financial incentives for the development of renewable energy sources, biofuels, and public transportation systems, and the measures allowing to protect the spending power of French people.

    1988-03-01

    This article is an analysis of patient choice of providers by the employees of the Security Pacific Bank of California and their dependents who have access to the Med Network Preferred Provider Organization (PPO). The empirical results show that not only is the PPO used by individuals who require relatively little medical care (as measured by predicted office visit charges) but that the PPO is most intensively used for low-risk services such as treatment for minor illness and preventive care. Also, the most likely Security Pacific Health Care beneficiary to use a PPO provider is a recently hired employee who lives in the south urban region, has a relatively low income, does not have supplemental insurance coverage, and is without previous attachments to non-PPO primary care providers. In order to maximize their ability to reduce plan paid benefits, insurers who contract with PPOs should focus on increasing PPO utilization among poorer health risks.

    Polyphenol oxidase (PPO) is an enzyme widely distributed in the plant kingdom that has been detected in most fruits and vegetables. PPO was extracted and purified from Manila mango (Mangifera indica), and its biochemical properties were studied. PPO was purified 216-fold by hydrophobic interaction and ion exchange chromatography. PPO was purified to homogeneity, and the estimated PPO molecular weight (MW) by SDS-PAGE was ≈31.5 kDa. However, a MW of 65 kDa was determined by gel filtration, indicating a dimeric structure for the native PPO. The isolated PPO showed the highest affinity to pyrogallol (Km = 2.77 mM) followed by 4-methylcatechol (Km = 3.14 mM) and catechol (Km = 15.14 mM). The optimum pH for activity was 6.0. PPO was stable in the temperature range of 20-70 °C. PPO activity was completely inhibited by tropolone, ascorbic acid, sodium metabisulfite, and kojic acid at 0.1 mM.

    We investigate planetary period oscillations (PPOs) in Saturn's magnetosphere using Cassini magnetic field data during the high cadence ( 7 days) F-ring and proximal orbits. Previous results have shown that there are two PPO systems, one in each hemisphere. Both PPO periods show seasonal dependence, and since mid-2014 the Northern PPO period has been 10.8 h and the Southern PPO period 10.7 h. The beat period of the two oscillations is 45 days. Previous results demonstrated that in the Northern (Southern) polar region only pure Northern (Southern) oscillations can be observed, whilst in the equatorial region both oscillations are present and constructively and destructively interfere over the beat-cycle of the two oscillations. The PPOs are believed to be driven by twin-cell convection patterns in the polar ionosphere/thermosphere regions, with two systems of field-aligned currents transmitting the PPO flows to the magnetospheric plasma.The F-ring and proximal orbits uniquely observe the PPOs over 6 orbits during each PPO beat cycle. This high-cadence data demonstrates that over a beat cycle both the periods and amplitudes of the PPO observed within the each polar region are modulated by the PPO system from the opposite hemisphere. When the two oscillations are in phase (anti-phase) the `drag' of one system on the other acts to decrease (increase) the amplitude of the oscillations and the two PPO periods diverge (converge). We present a theoretical model showing that this coupling is due to the PPO flows from one hemisphere not just being communicated to the magnetosphere as previously assumed, but also to the opposite hemisphere. The result is inter-hemispheric coupling of the PPO flow systems within the ionosphere/thermosphere system, so that the northern PPO system drives a northern twin-cell convection pattern in the southern hemisphere, and vice versa, thus leading to the observed polar modulations of the PPOs.We will also present PPO phase models determined

    We present results on the effect of the partial pressure of oxygen (ppo) on the structural and optical properties of tin-doped indium oxide, In 2 O 3 :Sn (ITO), thin films deposited on glass substrates by reactive dc diode sputtering. The deposition rate decreases with increasing ppo. The ppo did not affect the chemical composition of the ITO films as inferred from X-ray photoemission spectroscopy (XPS). From X-ray diffraction, we find out that the samples have crystalline structure in the ppo range 2 x 10 -4 to 6 x 10 -4 mbar and are amorphous outside this range. These samples have a preferred orientation for ppo between 2 x 10 -4 and 4.5 x 10 -4 mbar, but as the ppo increased beyond 4.7 x 10 -4 mbar, the texture dominates. This change occurs for the same substrate temperature (about 130 deg. C). The grain size decreases as the ppo increases. Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) have been used to investigate the surface roughness and the morphology of these samples. The optical transmission is greater than 90% in the visible region and does depend on the ppo. The refractive index n values are found to be in the 1.68-1.86 range. The energy gap values are between 3.1 and 3.5 eV.

    Wheat (Triticum aestivum L.), a major staple food for the people of Pakistan and other Asian countries, is used as bread, chapatti, porridge, noodles and many other. It is established that color quality of wheat products depend on chemical and enzymatic factors especially the polyphenol oxidases (PPOs). These are copper containing enzymes which induce browning in wheat-based products. Various procedures for determining PPO activity available and differences in PPO activity among wheat genotypes have been documented. In present study, an attempt was made to establish the association of molecular markers with polyphenol oxidase activity in wheat genotypes having very high or very low PPO activities. Twelve pairs of markers were used out of which only three primer pairs viz. PPO43, PPO30 and WP2-2 yielded specific pattern discriminating high and low PPO genotypes. Cluster analysis for all 12 markers revealed that all the low PPO lline share the same sub cluster, but high PPO lines were dispersed in different clusters. (author)

    Gentisic acid and cyanidin-3-O-glucoside are important bioactive polyphenols which are widely distributed in many fruits and cereals. In this work, kinetic study, spectral analysis and computational simulation were used to compare the inhibitory effects and inhibition mechanisms of gentisic acid and cyanidin-3-O-glucoside on mushroom polyphenoloxidase (PPO). The inhibitory effect of cyanidin-3-O-glucoside on PPO was much stronger than that of gentisic acid. Gentisic acid inhibited PPO in a reversible mixed-type manner while cyanidin-3-O-glucoside was an irreversible inhibitor. Gentisic acid and cyanidin-3-O-glucoside made the thermal inactivation of PPO easier, and induced apparent conformational changes of PPO. Compared with gentisic acid, cyanidin-3-O-glucoside had stronger effects on the thermal inactivation and conformation of PPO. Molecular docking results revealed gentisic acid bound to the active site of PPO by hydrogen bonding, π-π stacking and van der Waals forces. However, cyanidin-3-O-glucoside might irreversibly interact with the Met or Cys in PPO by covalent bonds. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The CHErenkov/Scintillation Separation experiment (CHESS) has been used to demonstrate the separation of Cherenkov and scintillation light in both linear alkylbenzene (LAB) and LAB with 2 g/L of PPO as a fluor (LAB/PPO). This is the first successful demonstration of Cherenkov light detection from the more challenging LAB/PPO cocktail and improves on previous results for LAB. A time resolution of 338 ± 12 ps FWHM results in an efficiency for identifying Cherenkov photons in LAB/PPO of 70 ± 3% and 63 ± 8% for time- and charge-based separation, respectively, with scintillation contamination of 36 ± 5% and 38 ± 4. LAB/PPO data is consistent with a rise time of τ{sub r} = 0.72 ± 0.33 ns. (orig.)

    Training at the optimal load for peak power output (PPO) has been proposed as a method for enhancing power output, although others argue that the force, velocity, and PPO are of interest across the full range of loads. The aim of this study was to examine the influence of load on PPO, peak barbell velocity (BV), and peak vertical ground reaction force (VGRF) during the jump squat (JS) in a group of professional rugby players. Eleven male professional rugby players (age, 26 ± 3 years; height, 1.83 ± 6.12 m; mass, 97.3 ± 11.6 kg) performed loaded JS at loads of 20-100% of 1 repetition maximum (1RM) JS. A force plate and linear position transducer, with a mechanical braking unit, were used to measure PPO, VGRF, and BV. Load had very large significant effects on PPO (p < 0.001, partial η² = 0.915); peak VGRF (p < 0.001, partial η² = 0.854); and peak BV (p < 0.001, partial η² = 0.973). The PPO and peak BV were the highest at 20% 1RM, though PPO was not significantly greater than that at 30% 1RM. The peak VGRF was significantly greater at 1RM than all other loads, with no significant difference between 20 and 60% 1RM. In resistance trained professional rugby players, the optimal load for eliciting PPO during the loaded JS in the range measured occurs at 20% 1RM JS, with decreases in PPO and BV, and increases in VGRF, as the load is increased, although greater PPO likely occurs without any additional load.

    Highlights: ► We synthesized novel immobilization carrier from reused DEAE-cellulose. ► We used it for immobilization of PPO through coordinative bonding with copper ions. ► Immobilized PPO showed better characteristics than soluble PPO. ► TC-PPO removed over 90% of halogenophenols at concentration of 100 mg/L. - Abstract: Halogenated compounds represent one of the most dangerous environmental pollutants, due to their widespread usage as biocides, fungicides, disinfectants, solvent and other industrial chemicals. Immobilization of a protein through coordinate bonds formed with divalent metal ions is becoming an attractive method due to its reversible nature, since the protein may be easily removed from the support matrix through interruption of the protein–metal bond hence giving inherently cleaner and cheaper technology for wastewater treatment. We have synthesized novel ‘tentacle’ carrier (TC) and used it for immobilization of partially purified potato polyphenol oxidase (PPO). The obtained biocatalyst TC-PPO showed pH optimum at 7.0–8.0 and temperature optimum at 25 °C. Immobilized PPO shows almost 100% of activity at 0 °C. TC-PPO was more resistant to the denaturation induced by sodium dodecyl sulphate (SDS) detergent as compared to its soluble counterpart and was even slightly activated at SDS concentration of 1%. TC-PPO was tested in the batch reactor for 4-chlorophenol and 4-bromophenol removal. More than 90% removal was achieved for both halogenophenols at concentration of 100 mg/L from aqueous solution. For both halogenophenols TC-PPO works with over 90% removal during first three cycles which decrease to 60% removal efficiency after six cycles each of 8 h duration.

    Previously, polyunsaturated fatty acids (PUFA) from linseed oil were effectively protected (>80%) against biohydrogenation through polyphenol-oxidase-mediated protein crosslinking of an emulsion, prepared with polyphenol oxidase (PPO) extract from potato tuber peelings. However, until now, emulsions of only 2 wt% oil have been successfully protected, which implies serious limitations both from a research perspective (e.g. in vivo trials) as well as for further upscaling toward practical applications. Therefore, the aim of this study was to increase the oil/PPO ratio. In the original protocol, the PPO extract served both an emulsifying function as well as a crosslinking function. Here, it was first evaluated whether alternative protein sources could replace the emulsifying function of the PPO extract, with addition of PPO extract and 4-methylcatechol (4MC) to induce crosslinking after emulsion preparation. This approach was then further used to evaluate protection of emulsions with higher oil content. Five candidate emulsifiers (soy glycinin, gelatin, whey protein isolate (WPI), bovine serum albumin and sodium caseinate) were used to prepare 10 wt% oil emulsions, which were diluted five times (w/w) with PPO extract (experiment 1). As a positive control, 2 wt% oil emulsions were prepared directly with PPO extract according to the original protocol. Further, emulsions of 2, 4, 6, 8 and 10 wt% oil were prepared, with 80 wt% PPO extract (experiment 2), or with 90, 80, 70, 60 and 50 wt% PPO extract, respectively (experiment 3) starting from WPI-stabilized emulsions. Enzymatic crosslinking was induced by 24-h incubation with 4MC. Ruminal protection efficiency was evaluated by 24-h in vitro batch simulation of the rumen metabolism. In experiment 1, protection efficiencies were equal or higher than the control (85.5% to 92.5% v. 81.3%). In both experiments 2 and 3, high protection efficiencies (>80%) were achieved, except for emulsions containing 10 wt% oil emulsions

    Polyphenol oxidase (PPO) was extracted and characterized from high-bush blueberries. PPO showed an optimum activity at pH 6.1-6.3 and 35°C, with the enzyme showing significant activity over a wide temperature range (25-60°C). Catechol was the most readily oxidized substrate followed by 4-methylcatechol, DL-DOPA, and dopamine. Blueberry PPO showed a K m of 15mM and V max of 2.57 ΔA 420 nm/min×10 -1 , determined with catechol. PPO was completely inactivated in 20min at 85°C, however, after 30minat 75°C it showed about 10% residual activity. Thermal treatment at 55 and 65°C for 30min resulted in the partial inactivation of PPO. Ascorbic acid, sodium diethyldithiocarbamic acid, L-cysteine, and sodium metabisulfite were effective inhibitors of PPO at 1.0mM. Benzoic acid and cinnamic acid series inhibitors showed relatively weak inhibition of PPO (21.8-27.6%), even at as high as 2.0mM concentration. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Insect phenoloxidase (PO belongs to the type 3 copper protein family and possesses oxidoreductase activities. PO is typically synthesized as a zymogen called prophenoloxidase (PPO and requires the proteolytic activation to function. We here cloned full-length cDNA for 3 previously unidentified PPOs, which we named OfPPO1a, OfPPO1b, and OfPPO3, from Asian corn borer, Ostrinia furnacalis (Gunée, in addition to the previously known OfPPO2. These conceptual PPOs and OfPPO2 all contain two common copper-binding regions, two potential proteolytic activation sites, a plausible thiol-ester site, and a conserved C-terminal region but lack a secretion signal peptide sequence at the N-terminus. O. furnacalis PPOs were highly similar to other insect PPOs (42% to 79% identity and clustered well with other lepidopteran PPOs. RT-PCR assay showed the transcripts of the 4 OfPPOs were all detected at the highest level in hemocytes and at the increased amounts after exposure to infection by bacteria and fungi. Additionally, we established an Escherichia coli (E. coli expression system to produce recombinant O. furnacalis PPO proteins for future use in investigating their functions. These insights could provide valuable information for better understanding the activation and functioning mechanisms of O. furnacalis PPOs.

    Color is a key quality trait of wheat-based products and polyphenol oxidase (PPO) is implicated to play a significant role in their undesirable darkening. Polyphenol oxidase catalyzes the oxidation of phenols to quinines, which auto oxidize and polymerize with amino acid of cellular proteins resulting brown and black pigmentation propounding reduced nutritional values. In present study, the PPO activity in 50 different Pakistani wheat cultivars was investigated and grouped into three categories viz; low, medium and high PPO activity cultivars. PPO is a heat labile enzyme. To investigate effect of heat stress, nine cultivars from each category were chosen for treatment at 30, 40 and 50 deg. C for 30, 60, and 120 minutes each. A substantial change was experienced in PPO activity as compared to room temperature. Two wheat cultivar Wafaq-2001 and AS-2002 showed a compromising attitude of minimum PPO activity at 30 deg. C for a period of 30 and 60 minutes of incubation. In general, an incubation of 30 deg. C or 60 deg. C (low or high) for a period of 30 minutes can be recommended for suppressing PPO activity.

    High-intensity interval training (HIIT) improves peak power output (PPO) in sedentary aging men but has not been examined in masters endurance athletes. Therefore, we investigated whether a six-week program of low-volume HIIT would (i) improve PPO in masters athletes and (ii) whether any change in PPO would be associated with steroid hormone perturbations. Seventeen male masters athletes (60 ± 5 years) completed the intervention, which comprised nine HIIT sessions over six weeks. HIIT sessions involved six 30-s sprints at 40% PPO, interspersed with 3 min active recovery. Absolute PPO (799 ± 205 W and 865 ± 211 W) and relative PPO (10.2 ± 2.0 W/kg and 11.0 ± 2.2 W/kg) increased from pre- to post-HIIT respectively ( P  HIIT (7.0 ± 1.2 ng/dL to 7.5 ± 1.1 ng/dL pre- to post-HIIT ( P  = 0.050, Cohen's d  = 0.40)). Six weeks' HIIT improves PPO in masters athletes and increases free testosterone. Taken together, these data indicate there is a place for carefully timed HIIT epochs in regimes of masters athletes. © 2017 The authors.

    Lychee polyphenoloxidase (PPO) was extracted and partially purified using ammonium sulphate precipitation and dialysis. The comparative analysis of PPO property was performed using its endogenous substrate (-)-epicatechin and exogenous substrate catechol. The pH optima for activity and activation temperature profiles of lychee PPO were very different when the enzyme reacted with endogenous and exogenous substrates. The addition of ethylenediaminetetraacetic acid disodium salt into the endogenous or exogenous substrate-enzyme system exhibited the same lowest inhibition of the PPO activity. However, l-cysteine was most effective in inhibiting enzymatic activity in the endogenous substrate-enzyme system while ascorbic acid was the best inhibitor in the exogenous substrate-enzyme system. Fe(2+) greatly accelerated the enzymatic reaction between endogenous substrate and PPO, but Cu(2+) exerted the same effect on the reaction between exogenous substrate and PPO. Based on the kinetic analysis, lychee PPO could strongly bind endogenous substrate but it possessed a higher catalytic efficiency to exogenous substrate. Copyright © 2007 Elsevier Ltd.

    A novel amphiphilic polymeric drug carrier was synthesized through grafting polymerization of water-soluble 1,4-β-D-glucan from cotton cellulose tailored and polypropylene oxide (PPO), and then use thereof to synthesize graft copolymer 1,4-β-D-glucan-PPO-docetaxel (DTX). The products were characterized by FTIR, 1 H NMR, and 13 C NMR. The physicochemical characteristics of 1,4-β-D-glucan-PPO and 1,4-β-D-glucan-PPO-DTX such as molecular weight distribution (MWD), micro-morphology, size, critical micelle concentration (CMC), aggregation number of micelle (N), in vitro stability and drug pharmacokinetic study in vivo were investigated. The results reveal that the degree of polymerization (DP) of the water-soluble 1,4-β-D-glucan from cotton cellulose tailored is equal to 7; the 1,4-β-D-glucan-PPO surfactant possesses good surface activity while the adduct number of propylene oxide reaches appropriately to 20; the DTX is completely dispersed in water medium with 1,4-β-D-glucan-PPO-DTX micelle and the drug conjugated percent is up to 40.3%; In vitro study confirms that 1,4-β-D-glucan-PPO-DTX has the capacity for sustained drug release; In plasma, 1,4-β-D-glucan-PPO-DTX exhibits a significantly enhanced C max , AUC (0-t) and T 1/2 compared with DTX. These results demonstrate that 1,4-β-D-glucan-PPO has the potential to be used as a novel biocompatible biomaterial for drug delivery. Copyright © 2018 Elsevier B.V. All rights reserved.

  8. Browning in Annona cherimola fruit: role of polyphenol oxidase and characterization of a coding sequence of the enzyme.

    Cherimoya (Annona cherimola Mill.) fruit is an attractive candidate for food processing applications as fresh cut. However, along with its desirable delicate taste, cherimoya shows a marked susceptibility to browning. This condition is mainly attributed to polyphenol oxidase activity (PPO). A general lack of knowledge regarding PPO and its role in the oxidative loss of quality in processed cherimoya fruit requires a better understanding of the mechanisms involved. The work carried out included the cloning of a full-length cDNA, an analysis of its properties in the deduced amino sequence, and linkage of its mRNA levels with enzyme activity in mature and ripe fruits after wounding. The results showed one gene different at the nucleotide level when compared with previously reported genes, but a well-conserved protein, either in functional and in structural terms. Cherimoya PPO gene (Ac-ppo, GenBank DQ990911) showed to be present apparently in one copy of the genome, and its transcripts could be significantly detected in leaves and less abundantly in flowers and fruits. Analysis of wounded matured and ripened fruits revealed an inductive behavior for mRNA levels in the flesh of mature cherimoya after 16 h. Although the highest enzymatic activity was observed on rind, a consistent PPO activity was detected on flesh samples. A lack of correlation between PPO mRNA level and PPO activity was observed, especially in flesh tissue. This is probably due to the presence of monophenolic substrates inducing a lag period, enzyme inhibitors and/or diphenolic substrates causing suicide inactivation, and proenzyme or latent isoforms of PPO. To our knowledge this is the first report of a complete PPO sequence in cherimoya. Furthermore, the gene is highly divergent from known nucleotide sequences but shows a well conserved protein in terms of its function, deduced structure, and physiological role.

    Highlights: • ΔFEV{sub 1.0} and ppoΔFEV{sub 1.0} using lobar collapsibility were strongly correlated. • ΔVC and ppoΔVC using effective lobar volume were strongly correlated. • Counting method was inferior to lobar collapsibility for prediction of ppoFEV{sub 1.0}. • Inspiratory/expiratory CT is useful to predict post-operative pulmonary function. - Abstract: Purpose: To compare the predictabilities of postoperative pulmonary function after lobectomy for primary lung cancer among counting method, effective lobar volume, and lobar collapsibility. Methods: Forty-nine patients who underwent lobectomy for primary lung cancer were enrolled. All patients underwent inspiratory/expiratory CT and pulmonary function tests 2 weeks before surgery and postoperative pulmonary function tests 6–7 months after surgery. Pulmonary function losses (ΔFEV{sub 1.0} and ΔVC) were calculated from the pulmonary function tests. Predictive postoperative pulmonary function losses (ppoΔFEV{sub 1.0} and ppoΔVC) were calculated using counting method, effective volume, and lobar collapsibility. Correlations and agreements between ΔFEV{sub 1.0} and ppoFEV{sub 1.0} and those between ΔVC and ppoΔVC were tested among three methods using Spearman’s correlation coefficient and Bland-Altman plots. Results: ΔFEV{sub 1.0} and ppoΔFEV{sub 1.0insp-exp} were strongly correlated (r = 0.72), whereas ΔFEV{sub 1.0} and ppoΔFEV{sub 1.0count} and ΔFEV{sub 1.0} and Pred. ΔFEV{sub 1.0eff.vol.} were moderately correlated (r = 0.50, 0.56). ΔVC and ppoΔVC{sub eff.vol.} (r = 0.71) were strongly correlated, whereas ΔVC and ppoΔVC{sub count}, and ΔVC and ppoΔVC {sub insp-exp} were moderately correlated (r = 0.55, 0.42). Conclusions: Volumetry from inspiratory/expiratory CT data could be useful to predict postoperative pulmonary function after lobectomy for primary lung cancer.

    Training at the optimal load for peak power output (PPO) has been proposed as a method for enhancing power output, although others argue that the force, velocity, and PPO are of interest across the full range of loads. The aim of this study was to examine the influence of load on PPO, peak barbell velocity (BV), and peak vertical ground reaction force (VGRF) during the jump squat (JS) in a group of professional rugby players. Eleven male professional rugby players (age, 26 ± 3 years; height, ...

    Introduction: We report the data of the first 100 patients who underwent sentinel lymph node biopsy (SLND) in our institution using lymphoscintigraphy only. Patients and methods: From 1998 to 2000, 100 consecutive patients (53 men and 47 women) with stage I or II melanoma (mean Breslow: 3.11 mm) underwent a SLND. Localisation of the sentinel node was performed by preoperative lymphoscintigraphy and hand held gamma probe detection. The sentinel node was examined by routine histology and immunohistochemistry for PS100 and HMB-45. If the sentinel node contained tumor cells, a complete lymphadenectomy was performed. Results: Lymphoscintigraphy was performed for 97 patients. The SLN was identified in 97% of cases (94/97) and excised in 95% of cases (92/97). The rate of SLN metastasis was 19/92 patients (21%), correlated with Breslow index (< 1.5 mm: 5%, 1.5-4 mm: 15%, > 4 mm: 46%). A mean number of 1.81 lymph node per patient was analysed. The mean follow-up was 26 months with a relapse in 14 patients, 5 of them having a metastatic sentinel node. Three patients had a recurrence at the site of the SLND although they had initially a negative sentinel node. Conclusion: The identification and metastatic rates of sentinel nodes are similar to those of the literature. More studies are needed to determine whether lymphoscintigraphy alone is efficient for successful SLND in melanoma. (author)

    Full Text Available The Transylvanian Late Medieval churches, like those in the west, were not integrally painted, with disparate votive or devotional images taking the place of the old hagiographic cycles, reflecting the indulgences and tradition of the Catholic Church. In this context, only a number of chapels preserve coherent ensembles: Hărman, Mediaş and Biertan. The program from Hărman stands as a mark for the iconography with the themes: Jesus in the midst of His Church with Apostles and Prophets bearing verses from the Creed (to the east, the Last Judgement (to the west, the Glorification of the Virgin Mary (in the center. Other ensembles including the Apostles’ Creed were also depicted in Mediaş (both church and chapel, Sânvăsii and Suseni (now lost. The Last Judgment, the most spread theme of the time is completed inside the chapel in Hărman with the Works of charity and the Parable of the poor Lazarus. Fragments are also preserved on the triumphal arch of St. Nicholas church of the same architectural ensemble above the later vault, in Mediaș (St. Margaret church, exterior, Apold, Chimindia, Bâra, Cetatea de Baltă, Sighișoara (with the personifications of the capital sins and the Limbo of the Children, Băgaciu (with a Purgatory prison. The Parable of the Ten Virgins, painted in the inner splay of the entrance from Hărman, is a further argument for the iconography of the chapels reproduced, in general terms, the iconography of the sanctuary of the churches, as in Sânvăsii, Suseni (known from the watercolour copies and old photos and, in the earlier ensembles from Apold or Nemşa. The association of the Last Judgment, as «the end of time» with the «beginning of time», illustrated by scenes from the life of Virgin Mary, is represented in Biertan (Annunciation, the Adoration of the Magi and Hărman (Annunciation, Defensorium Mariae, Crowning, Dormition. In Braşov and Bratei, the scene of the Annunciation was depicted too. the Evangelist – was also painted on the exterior at Delniţa and Mediaş chapel, with the donor, while individual Passion scenes, inspired by the “Seven Falls” of Christ, are preserved at Târgu Mureş and Sântimbru-Alba. The main themes of the late Transylvania murals show that beyond the changes of the artistic means of expression contamined by the Renaissance, the art of the voivodate remains even after 1500 faithful to the traditional iconography, reflecting the medieval thinking and mentality.

    The presented work was aimed at building a first VTR (virtual test reactor) to simulate irradiation effects in pressure vessel steels of nuclear reactor. It mainly consisted in: - modeling the formation of the irradiation induced damage in such steels, as well as their plasticity behavior - selecting codes and models to carry out the simulations of the involved mechanisms. Since the main focus was to build a first tool (rather than a perfect tool), it was decided to use, as much as possible, existing codes and models in spite of their imperfections. - developing and parameterizing two missing codes: INCAS and DUPAIR. - proposing an architecture to link the selected codes and models. - constructing and validating the tool. RPV-1 is made of five codes and two databases which are linked up so as to receive, treat and/or transmit data. A user friendly Python interface facilitates the running of the simulations and the visualization of the results. RPV-1 relies on many simplifications and approximations and has to be considered as a prototype aimed at clearing the way. According to the functionalities targeted for RPV-1, the main weakness is a bad Ni and Mn sensitivity. However, the tool can already be used for many applications (understanding of experimental results, assessment of effects of material and irradiation conditions,....). (O.M.)

    The NEMO3 detector, installed in the Frejus Underground Laboratory, is dedicated to the study of neutrinoless double beta decay: the observation of this process would sign the massive and Majorana nature of neutrino. The experiment consists in very thin central source foils (the total mass is equal to 10 kg), a tracking detector made of drift cells operating in Geiger mode, a calorimeter made of plastic scintillators associated to photomultipliers, a coil producing a 30 gauss magnetic field and two shields, dedicated to the reduction of the {gamma}-ray and neutron fluxes. In the first part, I describe the implications of several mechanisms, related to trilinear R-parity violation, on double beta decay. The second part is dedicated to a detailed study of the tracking detector of the experiment: after a description of the different working tests, I present the determination of the characteristics of the tracking reconstruction (transverse and longitudinal resolution, by Geiger cell and precision on vertex determination, charge recognition). The last part corresponds to the analysis of the data taken by the experiment. On the one hand, an upper limit on the Tl{sup 208} activity of the sources has been determined: it is lower than 68 mBq/kg, at 90% of confidence level. On the other hand, I have developed and tested on these data a method in order to analyse the neutrinoless double beta decay signal; this method is based on a maximum of likelihood using all the available information. Using this method, I could determine a first and very preliminary upper limit on the effective mass of the neutrino. (author)

    The LHCb experiment is one of the four particle physic detector installed at the new Large Hadron Collider (LHC) at CERN in Geneva. In order to reduce the amount of data storage for offline analysis, an online trigger system of interesting event according to the studied physic is implemented in parallel of the Data Acquisition system. The trigger system is composed by a first level (Level-0) made by a complex electronic system and a second level made by a computing system called the High Level Trigger. The Level-0 Decision Unit is the central part of the first trigger level that takes the decision to accept or to reject the event by using a fraction of information coming from the fastest sub-triggers (432 bits at 80 MHz). It is a full custom 16 layers board using advanced FPGA (Field Programmable Gate Array) in BGA (Bill Grid Array) package. Each sub-trigger transmit their data via high speed optical links running at 1.6 Gbit/s. The processing is implemented using a 40 MHz synchronous pipelined architecture. It performs a simple physical algorithm to compute the Level-0 trigger decision in order to reduce the data flow from 40 MHz down to 1 MHz for the next trigger level. The internal design of the processing FPGA is mainly composed by a Partial Data Processing (PDP) and a Trigger Definition Unit (TDU). The aim of the PDP is to adjust the clock phase, perform the time alignment, prepare the data for the TDU and monitor the data processing. The TDU is flexible and allows to fully re-configure all the trigger conditions through the Experiment Control System without any FPGA re-programming. (author)

    The two-proton radioactivity from the ground states was predicted by V.I. Goldanskii; it can take place either by {sup 2}He emission or by the simultaneous emission of two spatially non-correlated protons. For the nuclei liable to this type of radioactivity the single proton emission is energetically forbidden. The two-proton decay was observed for {sup 6}Be{sup 2} and {sup 12}O{sup 3} but the Q-value of the reaction is high above the Coulomb barrier and as such does not permit a decay process of a sufficient long lifetime. Theoretical calculations by B.A. Brawn predict {sup 39}Ti, {sup 45}Fe and {sup 48}Ni as the best candidates with the 2p emission lifetime within 1{mu}s to 150 ms. Only {sup 39}Ti decay has been observed so far. As candidate for 2p radioactivity nuclei we studied {sup 38}Ti, {sup 42}Cr, {sup 45}Fe and {sup 48`49}Ni. A primary beam of {sup 58}Ni at 600 MeV/nucleon from the SIS synchrotron at GSI was used to produce proton-rich isotopes in the titanium-to-nickel region by projectile fragmentation on a beryllium target. The fragment were separated by the projectile-fragment separator FRS and unambiguously identified by means of its standard detection set-up using a ToF-{Delta}E-B{rho} analysis. We report here the first observation of the T{sub Z} = - 7/2 nuclei {sup 45}Fe and {sup 49}Ni, the most proton-rich nuclei ever synthesized with an excess and seven protons. In addition, the new isotope {sup 42}Cr (T{sub Z} -3) was also identified. These isotopes are, according to commonly used mass predictions, all unbound with respect to two-proton emission from their ground states. However, we did not observe any count corresponding to {sup 38}Ti (T{sub Z} -3) although we expected about 5 counts in a setting optimized for this isotope 6 refs.

Cette imprégnation se traduit par une forte augmentation de l'énergie à la rupture du squelette céramique, permettant de limiter le risque de rupture fragile. L'augmentation des propriétés mécaniques des substituts osseux céramiques par une phase polymère peut être mise en regard des mécanismes de renforcement présents dans l'os et du rôle du collagène sur la ténacité de celui-ci. Dans une deuxième partie, des composites denses sont élaborés par des technologies de plasturgie, qui permettent de réaliser des produits de formes complexes. Les phases polymères et céramiques sont ici choisies pour leurs caractères respectifs résorbable et ostéo-inducteur. Ces composites permettent la création rapide d'hydroxyapatite à leur surface et accélèrent la guérison osseuse. A terme, ils sont résorbés. Ces deux exemples démontrent les potentialités de tels multi-matériaux architecturés pour la réalisation de substituts osseux plus résistants mécaniquement et apportant de nouvelles fonctionnalités, ainsi que pour la production de produits d'ostéosynthèse favorisant les processus de guérison osseuse. Here we show a brief outline of organic-inorganic composites for bone substitute and bone repair applications. Two types of composites are presented. In a first strategy, porous ceramics and bioactive glasses processed by sintering methods are impregnated by a polymer. The strong improvement of the mechanical properties of the ceramic scaffolds by a polymer phase can be linked to the one present in bone with the role of collagen on bone toughness. In a second strategy, a bioresorbable polymer and an osteo-inductive glass-ceramic in the form of fillers are chosen to process bone repair devices by polymer technologies (injection. The two examples presented show that architecture, multi-functional inorganic-organic composites can be processed for the development of devices able to improve bone regeneration processes.

    It is well known, if not well explained, that photo cross-sections curves depend on numerical resolution; as well as many other physical solutions from integral equations of the first kind, they are oscillating. In the first part of this report, a typical example points out how oscillations are growing. In the second part, a new method is explained yielding a smooth resolution. From experimental data on equidistant intervals, we build functions expanded in Tchebycheff polynomials; the solution is of this kind. Then, the third part points out that semi-analytical resolutions of this problem are illusive. (author) [French] C'est un fait reconnu mais mal explique, que les courbes de sections efficaces photonucleaires dependent de la resolution numerique adoptee. Beaucoup d'autres solutions physiques extraites d'une equation integrale de 1ere espece sont dans ce cas; elles sont arbitraires et oscillatoires. Dans la 1ere partie de ce rapport, on montre, dans un cas particulier typique, comment se forment les oscillations. Dans la 2eme partie, on presente une methode originale qui permet d'obtenir une resolution exempte d'oscillations. A partir de donnees experimentales a intervalles equidistants, on construit des fonctions developpees en polynomes de Tchebycheff; la solution est de ce type. Enfin, on montre dans la 3eme partie que les resolutions semi-analytiques de ce probleme sont illusoires. (auteur)

  3. Pourquoi la Commission de la santé et de la sécurité du travail du Québec n’est pas le premier recours des enseignantes et des préposées à l’aide domestique ayant des lésions professionnelles

    Full Text Available Cet article examine les motifs de deux groupes de travailleuses pour s’adresser ou pas à la Commission de la santé et de la sécurité du travail du Québec (CSST pour des lésions perçues comme étant liées au travail. Il est basé sur des entrevues qualitatives auprès de 16 enseignantes et de 16 préposées à l’aide domestique. Pour les deux groupes, les motifs de non-recours incluent la croyance que la CSST existe essentiellement pour les accidents et les retraits préventifs des femmes enceintes, l’image de la CSST comme un organisme qui accorde difficilement des indemnisations ainsi que la difficulté perçue de prouver le lien entre le travail et le problème de santé. Pour les préposées, le manque à gagner entre les prestations et le revenu d’emploi est aussi un facteur tandis que pour les enseignantes l’accès relativement facile à une assurance salaire joue contre le recours à la CSST. De plus, pour bien comprendre les choix des répondantes, il faut tenir compte de leur rapport à leur emploi et à leur santé et de la culture de leur milieu de travail.This article examines the motives behind the decisions of two groups of workers on whether or not to submit claims to the Workers’ Compensation Board (CSST for perceived work-related accidents or illnesses. It is based on qualitative interviews with 16 teachers and 16 cleaners. For both groups, motives for not making claims include the belief that the CSST is essentially for accidents and preventive work withdrawal for pregnant women, the view that compensation is difficult to obtain from the CSST, as well as a perceived difficulty of proving a relationship between their work and their health problem. For the cleaners, the difference between the compensation and employment income is also a factor, while for teachers, the fact that they have relatively easy access to wage-replacement insurance is one reason they do not submit claims to the CSST. To better understand the respondents’ choices, other factors such as their relationship to their job, their health, and their workplace culture must be taken into account.

    A protocol combining reduction mammaplasty (RM) and radiation therapy was developed as an alternative of mastectomy in patients with breast cancers larger than 3 cm in diameter. This protocol was used in 51 patients between 1983 and 1990. Indications were extensive microcalcifications (n = 17; 33 %) ; residual tumor after neo-adjuvant therapy larger than 4 cm in diameter (n 18 ; 35 %); extensive DCIS (n = 4; 8 %) or tumor located within an area of fibrocystic disease (n = 6; 12 %); presence of a bifocal lesion (n = 12 %); area of fibrocystic disease (n = 6; 12 %); and presence of bifocal lesion (n 6; 12 %). Surgery consisted of tumor-ectomy removing a wide margin of skin and mammary gland, followed by immediate remodeling of the breast, same-side axillary node clearance, and symmetrization of the other breast. A radiation dose of 45 Gy was delivered to the entire mammary gland. Adjuvant therapy was given before and/or after therapy according to the institution`s routine breast cancer protocol. During the mean follow-up of 8.1 years, four patients (8 %) developed a local recurrence, which has treated surgically. The five-year disease-free survival rate was 76 %. The cosmetic result was good or very good in 78% of cases. RM plus RT is a reasonable alternative to mastectomy in patients with large breast cancers, although further work is needed to refine its indications. (authors). 15 refs.

    This document, taking as a starting point the needs brought about by the evolution of the gas market, shows two proposals for technological innovations to be applied to company processes, to increase the quality and the opportunities supplied to clients for the gas distribution service. This article will deal with in particular the rationalization of the billing process giving a wider interpretation than the one commonly followed. As for the first proposal - the remote reading of domestic meters - the experimental project carried out on a sample of Italcogim clients is analysed in detail, as well as their related technical results regarding the efficiency and effectiveness of the technology used. An evaluation quality criteria on the suitability of the use of the new remote reading system is also highlighted. The second proposal covers the rechargeable card system, with a description of the technical and economic planning applied to the pilot project which will start in the near future. (authors)

Contudo, relativamente ao treino de Futebol constata-se que a componente psicológica é muito negligenciada. Neste estudo, procura-se conhecer as percepções de treinadores de alto rendimento acerca de diferentes aspectos relacionados com a dimensão psicológica, nomeadamente as concepções sobre o treino psicológico e a sua relação com o treino e o rendimento desportivo; o nível de preparação dos treinadores para treinar as competências psicológicas; e a relevância de colaborar com um especialista em psicologia do desporto. Com recurso a uma entrevista semi-estruturada, foram entrevistados quinze treinadores da Primeira Liga de Futebol Portuguesa. Uma análise indutiva das entrevistas revelou que os treinadores atribuem grande importância à componente psicológica e à colaboração com um especialista em psicologia do desporto, até porque não se sentem preparados para desenvolver um treino sistemático neste domínio.Sport performance results from the interaction of physical, technical, tactical and psychological aspects. However, in Soccer training less attention is devoted to the psychological domain. The purpose of this study was to investigate elite Soccer coaches' perceptions concerning different aspects of the psychological dimension, namely the conceptions about mental training and his relationship with training, in general, and performance; the coaches' level of preparation to apply a specific psychological training; and the collaboration with a sport psychology expert. Using in-depth interviews, fifteen coaches of the Portuguese first league were interviewed. The interviews showed that the coaches attribute great significance to the psychological domain and to a possible collaboration with a sport psychology expert, as coaches seem to be unprepared to apply specific mental strategies or are unfamiliar with them.

    The Piedra Museo site (Santa Cruz, Argentina), excavated over the past nine years has yielded a rich archaeological record, which contributes to the discussion on the first peopling of the Americas. We present here a new study of the site, based on an analysis of the stratigraphy, spatial distribution of archaeological remains, bone taphonomy, and discussion of new AMS- 14C dates. We conclude that remains of extinct species with cut-marks from the lower levels are contemporaneous of stone tools and cores from the same levels. This demonstrates that humans were present in the southern part of Patagonia around 10 300 and 11 100 years BP and suggests that hunting of large mammals was a part of their subsistence strategies.

    This thesis reports the first results towards the realization of an optical clock using trapped strontium atoms. This set up would combine advantages of the different approaches commonly used to develop an atomic frequency standard. The first part describes the cold atoms source which is implemented. A magneto-optical trap operating on the {sup 1}S{sub 0}-{sup 1}P{sub 1} transition at 461 nm is loaded from an atomic beam decelerated by a Zeeman slower. The 461 nm laser is obtained by sum-frequency mixing in a potassium titanyl phosphate (KTP) crystal. The second part is devoted to the different stages developed to achieve the direct excitation of the {sup 1}S{sub 0}-{sup 3}P{sub 0} clock transition in {sup 87}Sr. This line has a theoretical natural width of 10{sup -3} Hz. Before this detection, we obtained an estimate of the resonance frequency by measuring absolute frequencies of several allowed optical transitions. (author)

    Retrospective analysis of the treatment of choroidal melanoma with proton-therapy at the Centre de protontherapie d`Orsay, France. Between September 1991 and September 1995, 612 patients presenting with choroidal melanoma were treated by proton-therapy in Orsay. Following initial management of the first 464 patients, results were analyzed, as were results after a 1-year follow up for 305 patients, a 2-year follow-up for 169 patients, and a 3-year follow-up for 59 patients. Univariate analysis showed that the actuarial local recurrence rate was 5 %, the 3-year survival rate 88 %, and the overall metastatic rate 5%. The initial tumor volume was the most significant predictive factor for visual results and metastases. Multivariate analysis revealed that visual results were significantly related to the initial tumor volume, initial retinal detachment, and total dose delivered to the optic nerve and macula. Proton-therapy of choroidal melanoma allows in most cases conservation of the eye without modification of survival. Visual results mainly depend on the site and size of the tumor. (author) 16 refs.

    In the framework of the Quantum Chromodynamics (QCD), the nucleon is described as being composed of three valence quarks surrounded by a sea of virtual quark-antiquark pairs and gluons. If the role of this virtual sea in the nucleon properties is inferred to be important, this contribution is still poorly understood. In this context, we study the role of the strange quarks in the nucleon since this is the lightest quark flavor of the sea with no valence contribution. We are determining its contribution to the charge and magnetization distributions in the nucleon via parity violation experiments. The measurement is performed by elastically scattering polarized electrons from nucleon target. A world wide program in which the G0 experiment takes place has been performing for a decade. The G0 experiment and the analysis of the results from its forward angles phase are the topics of this thesis. This document presents the physics case of the strangeness content of the nucleon (mass, spin, impulsion). It describes also the formalism related to the electroweak probe and the form factors, and then the principle of parity violating asymmetry measurement. The G0 experimental setup, which was built and installed in the Hall C of the Jefferson Laboratory (Usa), is detailed. This set-up was designed for the measurement of asymmetries of the order of 10{sup -6} with an overall relative uncertainty better than 10 %, over a momentum transfer range 0.1-1 (GeV/c){sup 2}. The various steps of the data analysis are exposed. They have allowed us to start from measured counting rates to reach parity violating physics asymmetries. This required a careful treatment of the various sources of systematical errors which is discussed extensively. Finally the results from the G0 forward angle measurement, its comparison with others experiments and with theoretical models, are presented. They support a non null strange quark contribution.

    We present a study of Gd+U collisions at 36 AMeV measured with the INDRA multidetector, permitting almost complete detection (over 80%) of all the reaction products. We show that events exist which correspond to the multifragmentation of a single system comprising the majority of the nucleons for a cross-section of 2.6 mbarn, by isolating reactions for which the emitted fragments have lost all memory of the entrance channel. Such reactions correspond to neither the most central collisions nor the most isotropic events (in the fragments` momentum space), and therefore cannot be correctly distinguished from the dominant binary deeply-inelastic collisions using these criteria. An initial comparison of the selected data with a statistical code indicates that fragments are formed in a dilute, compact system, undergoing a self-similar expansion corresponding to a collective energy of between 1 and 1.5 MeV. Comparison with the same type of events observed in Xe+Sn collisions at 32 AMeV reveals the existence of a scaling law for the multifragmentation of systems of different mass at the same excitation energy per nucleon: fragment Z distributions are identical while their multiplicity increases proportionally to the mass of the multi-fragmenting system. This observation is interpreted as an experimental signal that this multifragmentation originates in a bulk instability of low-density nuclear matter (spinodal region). A complete semi-classical microscopic calculation for the two reactions, including the formation and multifragmentation by spinodal decomposition of very heavy, low-density systems, reproduces very well not only the experimental fragment multiplicities and Z distributions but also their mean kinetic energies, as well as the size distributions of the largest fragments.

    The aim of this study is to compare two calculation methods implemented in the neutronic code CRONOS 2: the diffusion approximation and the SP{sub n} method. The APOLLO 2 code is used to build the multiparameter cross section libraries.The comparison is based on the first core of N4 type Chooz reactor. The rod worth and the power map have been calculated. Some recommendations about the SP{sub n} development order of flux are made and the results show that the diffusion calculations over-estimate the black rod efficiency up to 10%. (A.C.) 12 refs.

    The H.E.S.S. (High Energy Stereoscopic System) experiment in gamma-ray Astronomy consists of four imaging atmospheric Cherenkov telescopes devoted to the observation of the gamma-ray sky in the energy domain above 100 GeV and extending up to several tens of TeV. This thesis presents a new reconstruction method of gamma-ray induced air showers which takes full advantage of the stereo-scopy and of the fine-grain imaging of the H.E.S.S. cameras. This new method provides an angular resolution better than 0.1 angle, an energy resolution of about 15% at zenith and a very efficient hadronic rejection based on a cut on the lateral spread of the electromagnetic shower which does not depend on simulations. A new background subtraction method, well adapted to the study of extended sources, was also developed. No assumption, either on the distribution of gamma-rays in the field of view, or on the distribution of hadrons are necessary. It provides two sky maps obtained from a maximum likelihood fit: one for {gamma}-rays and the other for hadrons. These two analysis methods were applied to the study of the shell-type supernova remnants RX J1713.7-3946 and RX J0852.0-4622 (Vela Junior), allowing for the first time to resolve their morphology in the gamma-ray domain. The study of these sources should answer the question: 'can shell-type supernova remnants accelerate cosmic-rays up to the knee (5 x 10{sup 15} eV)?'. A morphological and spectral study of these sources combined with a comparison of a simple model of emission processes (from electrons and protons accelerated in supernova remnants) provides some constraints on the parameters of the leptonic process. Nevertheless, this scenario cannot be excluded. The different results obtained are discussed and compared with a third shell-type supernova remnant observed by H.E.S.S. but not detected: SN 1006.

    The NEMO3 detector, installed in the Frejus Underground Laboratory, is dedicated to the study of neutrinoless double beta decay: the observation of this process would sign the massive and Majorana nature of neutrino. The experiment consists in very thin central source foils (the total mass is equal to 10 kg), a tracking detector made of drift cells operating in Geiger mode, a calorimeter made of plastic scintillators associated to photomultipliers, a coil producing a 30 gauss magnetic field and two shields, dedicated to the reduction of the {gamma}-ray and neutron fluxes. In the first part, I describe the implications of several mechanisms, related to trilinear R-parity violation, on double beta decay. The second part is dedicated to a detailed study of the tracking detector of the experiment: after a description of the different working tests, I present the determination of the characteristics of the tracking reconstruction (transverse and longitudinal resolution, by Geiger cell and precision on vertex determination, charge recognition). The last part corresponds to the analysis of the data taken by the experiment. On the one hand, an upper limit on the Tl{sup 208} activity of the sources has been determined: it is lower than 68 mBq/kg, at 90% of confidence level. On the other hand, I have developed and tested on these data a method in order to analyse the neutrinoless double beta decay signal; this method is based on a maximum of likelihood using all the available information. Using this method, I could determine a first and very preliminary upper limit on the effective mass of the neutrino. (author)

    Baroque style arose almost simultaneously in France and Italy in the late sixteenth century. Musical language underwent profound modification. Passage from a modal to a tonal system altered ornamentation and tone. The work of scholarly enthusiasts opened the way for the emergence of a new, monodic vocal style, in which it was possible to ’speak while singing’, recitar cantando. During this period, Occitan civilisation, all hope of political independence relinquished, shot its last sparks amon...

    Biofuel is a solution to reduce the dependence of fossil fuels. Pure Plant Oil (PPO) of Calophyllum inophyllum L. is a potential raw material for green diesel through the processes of deoxygenation, hydrotreating, and isomerization. Deoxygenation of the PPO with NiMo / Al2O3 catalyst was carried out in a stirred autoclave reactor at a temperature of 300 - 400°C for 3 hours, and the water/PPO ratio was 1:2 and 1:4. The result showed that deoxygenation would work more effective at high temperature as indicated by higher CO and CO2 resulting from carboxylation and carbonylation. In addition, raising the reaction temperature from 300 to 400°C succeeded in increasing the diesel fraction of C16 - C20 by 33.01% and decreased the fraction of C21-C25 by 2.41%. Increasing water/ppo ratio did not give any significant improvement on green diesel products.

    High-performance polymer memory is fabricated using blends of ferroelectric poly(vinylidene-fluoride-trifluoroethylene) (P(VDF-TrFE)) and highly insulating poly(p-phenylene oxide) (PPO). The blend films spontaneously phase separate into amorphous PPO nanospheres embedded in a semicrystalline P(VDF-TrFE) matrix. Using low molecular weight PPO with high miscibility in a common solvent, i.e., methyl ethyl ketone, blend films are spin cast with extremely low roughness (Rrms ≈ 4.92 nm) and achieve nanoscale phase seperation (PPO domain size < 200 nm). These blend devices display highly improved ferroelectric and dielectric performance with low dielectric losses (<0.2 up to 1 MHz), enhanced thermal stability (up to ≈353 K), excellent fatigue endurance (80% retention after 106 cycles at 1 KHz) and high dielectric breakdown fields (≈360 MV/m). © 2013 WILEY-VCH Verlag GmbH & Co.

    Posttraumatic and postoperative osteomyelitis (PPO) is a subgroup of bone infections with increasing importance. However, to date no standardized reoperation concept exists particularly for patients with PPO of the shoulder region. Therefore the purpose of this study was to evaluate a revision concept including débridement, irrigation, and insertion of temporary drainage with hardware retention until healing. A total of 31 patients with PPO were included with a proximal humerus fracture (n = 14), clavicle fracture (n = 10), or AC-joint separation (n = 7). In all, 27 of these patients could be followed for > 1 year. Hardware retention until fracture or ligament healing could be achieved in > 83%. Six patients required follow-up débridement due to recurrent infections, but then were unremarkable. Clinical outcome showed excellent Constant scores (91.6 ± 2.8). A cost-efficient, simple, and successful revision concept for patients with PPO of the shoulder region is described.

    To investigate the influence of both the first luminescent additive and the wavelength-shifter on the performance of plastic scintillator, a series of polystyrene-based scintillator had been prepared by thermal polymerization. Three first luminescent additives (PPO, p-TP and b-PBD) and four wavelength-shifters (POPOP, Bis-MSB, Me-MSB and DPA) were added to the scintillators respectively. The comparison results showed that PPO and POPOP were the most adequate fluorescent dyes for the polystyrene-based plastic scintillator. Moreover, with the increase of the concentration of PPO and POPOP, the fluorescence intensity and light yield were increased firstly and then decreased. The plastic scintillator containing 2% PPO and 0.02% POPOP had the highest fluorescence intensity and light yield.

    Full Text Available Abstract Background Plant polyphenol oxidases (PPOs are enzymes that typically use molecular oxygen to oxidize ortho-diphenols to ortho-quinones. These commonly cause browning reactions following tissue damage, and may be important in plant defense. Some PPOs function as hydroxylases or in cross-linking reactions, but in most plants their physiological roles are not known. To better understand the importance of PPOs in the plant kingdom, we surveyed PPO gene families in 25 sequenced genomes from chlorophytes, bryophytes, lycophytes, and flowering plants. The PPO genes were then analyzed in silico for gene structure, phylogenetic relationships, and targeting signals. Results Many previously uncharacterized PPO genes were uncovered. The moss, Physcomitrella patens, contained 13 PPO genes and Selaginella moellendorffii (spike moss and Glycine max (soybean each had 11 genes. Populus trichocarpa (poplar contained a highly diversified gene family with 11 PPO genes, but several flowering plants had only a single PPO gene. By contrast, no PPO-like sequences were identified in several chlorophyte (green algae genomes or Arabidopsis (A. lyrata and A. thaliana. We found that many PPOs contained one or two introns often near the 3’ terminus. Furthermore, N-terminal amino acid sequence analysis using ChloroP and TargetP 1.1 predicted that several putative PPOs are synthesized via the secretory pathway, a unique finding as most PPOs are predicted to be chloroplast proteins. Phylogenetic reconstruction of these sequences revealed that large PPO gene repertoires in some species are mostly a consequence of independent bursts of gene duplication, while the lineage leading to Arabidopsis must have lost all PPO genes. Conclusion Our survey identified PPOs in gene families of varying sizes in all land plants except in the genus Arabidopsis. While we found variation in intron numbers and positions, overall PPO gene structure is congruent with the phylogenetic

  8. PMP, a novel solute for liquid and plastic scintillation counting

    International Nuclear Information System (INIS)

    Gusten, Hans

    1983-01-01

    The excellent fluorescence properties of PMP ( 11-phenyl-3-mesityl-2-pyrazoline) such as long wavelength emission of over 400 nm, and high fluorescence quantum yield with a short decay time together with a solubility of more than one Mol/L in toluene make this compound a promising solute for scintillation counting. The Stokes' shift of PMP of over 10,000 cm -1 is twice as large as that of the commonly used PPO. Due to this unusually large Stokes' shift PMP can be used as a primary solute without requiring a secondary solute as wavelength shifter. A comparison of the scintillation properties of PMP and PPO in toluene reveals that the counting efficiency for 14 C is better for PMP while the 3 H efficiency is equally good. Due to the large Stokes' shift, PMP is about 50 percent less sensitive to color quenching than PPO. Compared to the solute combinations PPO/secondary solutes, the scintillation counting efficiency of PMP for 14 C in toluene or xylene is the same, while the absolute 3 H efficiency of PPO/secondary solutes in cocktails with emulsifiers is about 10 percent higher. The PMP scintillation efficiency for 14 C as well as 3 H in chemical quenching by urine is more or less the same as for PPO/dimethyl-POPOP. PMP is more sensitive to quenching by halogenated solvents. In the dioxane-based scintillation, this sensitivity to chemical quenching by CHCl 3 vanishes and the counting efficiencies for 14 C and 3 H are as good as for PPO/dimethyl-POPOP or PPO/bis-MSB. Due to the large Stokes' shift, the self-absorption of the scintillation light by PMP is lower than in conventional scintillators. This offers good possibilities in very large-volume applications of liquid as well as plastic scintillators

    2014-03-01

    Full Text Available The thermal inactivation of yeast isolated from spoiled Jubileu peach puree and that of polyphenoloxidase (PPO and peroxidase (POD in cv. Jubileu, which is widely cultivated in southern Rio Grande do Sul state, Brazil, were studied. PPO and POD were extracted using the protein powder method and submitted to partial purification by precipitation followed by dialysis. The enzymatic activity was determined measuring the increase in absorbance at 420 nm for PPO and 470 nm for POD. The yeast used in this investigation was isolated from spoiled Jubileu peach puree at 22 °Brix, with total initial microbial count of 22 × 10² UFCmL- 1. Stock cultures were maintained on potato dextrose agar (PDA slants at 4 °C and pH 5 for later use for microbial growth. In all cases, kinetic analysis of the results suggests that the thermal inactivation was well described by a first-order kinetic model, and the temperature dependence was significantly represented by the Arrhenius law. Both enzymes were affected by heat denaturation, and PPO was more thermostable. PPO was also more thermosTable than the yeast isolated from peach puree. The D60-values were 1.53 and 1.87 min for PPO and yeast isolated from spoiled Jubileu peach puree, respectively.

    Poloxamers are low molar mass triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), having number of applications as non-ionic surfactants. Comprehensive one and two-dimensional liquid chromatographic (LC) analysis of these materials is proposed in this study. The separation of oligomers of both types (PEO and PPO) is demonstrated for several commercial poloxamers. This is accomplished at the critical conditions for one of the block while interaction for the other block. Reversed phase LC at CAP of PEO allowed for oligomeric separation of triblock copolymers with regard to PPO block whereas normal phase LC at CAP of PPO renders oligomeric separation with respect to PEO block. The oligomeric separation with regard to PEO and PPO are coupled online (comprehensive 2D-LC) to reveal two-dimensional contour plots by unconventional 2D IC×IC (interaction chromatography) coupling. The study provides chemical composition mapping of both PEO and PPO, equivalent to combined molar mass and chemical composition mapping for several commercial poloxamers.

    We fabricated quantum-dot doped plastic scintillators in order to control the emission wavelength. We studied the characterization of the quantum-dots (CdSe/ZnS) and PPO (2, 5-diphenyloxazole) doped styrene based plastic scintillators. PPO is usually used as a dopant to enhance the scintillation properties of organic scintillators with a maximum emission wavelength of 380 nm. In order to study the scintillation properties of the quantum-dots doped plastic scintillators, the samples were irradiated with X-ray, photon, and 45 MeV proton beams. We observed that only PPO doped plastic scintillators shows a luminescence peak around 380 nm. However, both the quantum-dots and PPO doped plastic scintillators shows luminescence peaks around 380 nm and 520 nm. Addition of quantum-dots had shifted the luminescence spectrum from 380 nm (PPO) toward the region of 520 nm (Quantum-dots). Emissions with wavelength controllable plastic scintillators can be matched to various kinds of photosensors such as photomultiplier tubes, photo-diodes, avalanche photo-diodes, and CCDs, etc. Also quantum-dots doped plastic scintillator, which is irradiated 45 MeV proton beams, shows that the light yield of quantum-dots doped plastic scintillator is increases as quantum-dots doping concentration increases at 520 nm. And also the plastic scintillators were irradiated with Cs-137 γ-ray for measuring fluorescence decay time. -- Highlights: • Quantum-dot doped plastic scintillator is grown by the thermal polymerization method. • Quantum-dot doped plastic scintillators can control the emission wavelength to match with photo-sensor. • Quantum-dots and PPO doped plastic scintillators emitted luminescence peaks around 380 nm and 520 nm. • We observed the energy transfer from PPO to quantum-dot in the quantum-dot doped plastic scintillator

    The catalytic oxidation of phenolic substrates by polyphenoloxidase (PPO) causes pericarp browning of postharvest rambutan fruit. In the present study, PPO and its endogenous substrates were extracted from rambutan pericarp tissues (RPT). The substrate extracts were sequentially partitioned with ethyl acetate and n-butanol. The analysis of total phenolic content showed that the most phenolic compounds were distributed in ethyl acetate fraction. By high-performance liquid chromatography (HPLC), (-)-epicatechin (EC) and proanthocyanidin A2 (PA2) were identified from this fraction. After reacting with rambutan PPO, EC turned brown rapidly within 10 min, indicating that it was a significant endogenous substrate. Although PA2 could also be oxidized by the PPO, it turned brown very slowly. In addition, because EC and PA2 were continually catalyzed into browning products by PPO during storage of the fruit at 4 and 25 degrees C, their contents in RPT gradually declined with the extended storage time. It was further observed that both substrate contents in rambutan fruit storing at 25 degrees C decreased more rapidly than that storing at 4 degrees C, suggesting that low temperature inhibited the catalytic oxidation of substrates so as to slow down pericarp browning. Practical Application: Pericarp browning is a serious problem to storage and transport of harvested rambutan fruit. A generally accepted opinion on the browning mechanism is the oxidation of phenolic substrates by PPO. Ascertaining PPO substrates will effectively help us to control enzymatic reaction by chemical methods so as to delay or even prevent pericarp browning of harvested rambutan fruit.

    The use of heavy resistance exercise provides an effective preload stimulus for inducing postactivation potentiation (PAP) and increasing peak power output (PPO). However, this approach has limited application in many sporting situations (e.g., incorporation in a precompetition warm-up); and therefore, more practical strategies for inducing PAP need to be investigated. The aim of the present study was to compare the PPO changes after performing a preload stimulus of either a ballistic exercise or a traditional heavy resistance exercise. Twenty professional rugby union players completed 3 testing sessions, each separated by 48 hours. On the first occasion, subjects underwent a 3 repetition maximum (3RM)-bench press testing session. On the next 2 occasions, subjects performed a ballistic bench throw at baseline (30% of 1RM), followed by a preload stimulus of either heavy resistance training (HRT) (heavy bench press: 3 sets of 3 repetitions at 87% 1RM) or BBP (3 sets of 3 repetitions at 30% on 1RM) followed by ballistic bench throw after 8 minutes recovery. The trials were randomized and counterbalanced. Both preload stimuli protocols increased PPO compared with baseline (BBP baseline 892 ± 108 vs. 8 minutes 924 ± 119 W, p < 0.001; HRT baseline 893 ± 104 vs. 8 minutes 931 ± 116 W; p < 0.001). There were no conditional differences between PPO at 8 minutes (p = 0.141); moreover, the change in PPO from baseline was also similar between conditions (BBP Δ + 33 ± 18; HRT Δ + 38 ± 21 W; p = 0.112). In conclusion, a ballistic exercise provided an effective method of inducing PAP and increasing upper-body PPO; moreover, this elicited similar increases in PPO as a traditional heavy resistance exercise preloading stimulus.

    Full Text Available High-intensity interval training (HIIT improves peak power output (PPO in sedentary aging men but has not been examined in masters endurance athletes. Therefore, we investigated whether a six-week program of low-volume HIIT would (i improve PPO in masters athletes and (ii whether any change in PPO would be associated with steroid hormone perturbations. Seventeen male masters athletes (60 ± 5 years completed the intervention, which comprised nine HIIT sessions over six weeks. HIIT sessions involved six 30-s sprints at 40% PPO, interspersed with 3 min active recovery. Absolute PPO (799 ± 205 W and 865 ± 211 W and relative PPO (10.2 ± 2.0 W/kg and 11.0 ± 2.2 W/kg increased from pre- to post-HIIT respectively (P < 0.001, Cohen’s d = 0.32−0.38. No significant change was observed for total testosterone (15.2 ± 4.2 nmol/L to 16.4 ± 3.3 nmol/L (P = 0.061, Cohen’s d = 0.32, while a small increase in free testosterone occurred following HIIT (7.0 ± 1.2 ng/dL to 7.5 ± 1.1 ng/dL pre- to post-HIIT (P = 0.050, Cohen’s d = 0.40. Six weeks’ HIIT improves PPO in masters athletes and increases free testosterone. Taken together, these data indicate there is a place for carefully timed HIIT epochs in regimes of masters athletes.

    We fabricated quantum-dot doped plastic scintillators in order to control the emission wavelength. We studied the characterization of the quantum-dots (CdSe/ZnS) and PPO (2, 5-diphenyloxazole) doped styrene based plastic scintillators. PPO is usually used as a dopant to enhance the scintillation properties of organic scintillators with a maximum emission wavelength of 380 nm. In order to study the scintillation properties of the quantum-dots doped plastic scintillators, the samples were irradiated with X-ray, photon, and 45 MeV proton beams.

    1. An experiment was conducted to study the comparative effects of peach palm oil (PPO, Bactris gasipaes H.B.K), crude palm oil (CPO, Elaeis guinenesis), maize oil (MO) and beef tallow (BT) on serum total and lipoprotein cholesterol levels and haemostatic factors in broiler chickens. 2. Four experimental diets were formulated to be isocaloric (14·2 MJ AME(N)/kg) and isonitrogenous (230 g CP/kg). PPO was extracted from the whole dry fruit with hexane. Each fat was added to the diet in an amount equivalent to 25% of total dietary calories. Six replicate groups of eight male broiler chicks were assigned randomly to each dietary treatment. Diets were fed on ad libitum basis. The experiment lasted 42 d. 3. At 42 d, birds were fasted overnight and three chickens/dietary treatment were utilised to draw blood for lipoprotein separation. Various haemostatic factors were determined in thrombocyte-poor plasma. Thrombocyte aggregation was assayed in whole blood. 4. No significant differences were detected in body-weight gain or feed efficiency between the chickens fed on the PPO diet and those receiving the CPO, MO or BT diets. Total serum cholesterol (TC), very low density lipoprotein cholesterol and low density lipoprotein cholesterol (LDL(C)) were not significantly affected after consuming the PPO, CPO and MO diets. Serum high density lipoprotein cholesterol (HDL(C)) was reduced only by the MO diet. Birds fed on the PPO diet had a significantly lower [corrected] LDLC/HDLC ratio compared with other dietary treatments 5. Thrombocyte count and thrombin time were not significantly affected by the experimental diets. Dietary oils significantly affected prothrombin time, fibrinogen concentration and thrombocyte aggregation. PPO and MO diets elicited the lowest fibrinogen levels compared to the CPO and BT diets. Thrombocyte aggregation in broilers fed on the PPO diet was similar to that of the CPO, MO and BT diets. 6. The results suggest that PPO might efficiently provide up to
