Résumé :

This paper reviews the use of optical sum frequency generation (SFG) and second harmonic generation (SHG) microscopy under ultra-high vacuum (UHV) conditions to observe the dynamics of a hydrogen terminated Si(111)1 × 1 surface. First, we took SFG and SHG microscopic images of the surface after IR light pulse irradiation and found that the SHG and nonresonant SFG signals were enhanced, probably due to the formation of dangling bonds after hydrogen desorption. Second, we observed time-resolved SFG intensity images of a H–Si(111)1 × 1 surface. After visible pump light irradiation, the nonresonant SFG signal increased at probe delay time 0 ps and then decreased over a life time of 565 ps. The resonant SFG signal reduced dramatically at 0 ps and then recovered with an anisotropic line shape over a life time of 305 ps. The areas of modulated SFG signals at delay time 277 ps were expanded with an anisotropic aspect. Finally, we observed SFG intensity images of hydrogen deficiency on a Si(111)1 × 1 surface as a function of temperature. These images of the H–Si(111) surface, taken with a spatial resolution of 5 μm at several temperatures from 572 to 744 K, showed that the hydrogen desorbs homogeneously.

Résumé :

X-ray diffraction (XRD) results indicate that the NiFe thin films had a face-centered cubic (FCC) structure. Post-annealing treatment increased the crystallinity of NiFe films over those at room temperature (RT), suggesting that NiFe crystallization yields FCC (111) texturing. Post-annealing treatments increase crystallinity over that obtained at RT. This paper focuses on the maximum alternative-current magnetic susceptibility(χac)value of NiFe thin films with resonance frequency(fres)at low frequencies from 10 Hz to 25000 Hz. These results demonstrate that theχacof NiFe thin films increased with post-annealing treatment and increasing thickness. The NiFe (111) texture suggests that the relationship between magneto-crystalline anisotropy and the maximumχacvalue with optimal resonance frequency(fres)increased spin sensitivity at optimalfres. The results obtained under the three conditions revealed that the maximumχacvalue and optimalfresof a 1000 Å-thick NiFe thin film are 3.45 Hz and 500 Hz, respectively, following postannealing atTA=250°C for 1 h. This suggests that a 1000 Å NiFe thin film post-annealed atTA=250°C is suitable for gauge sensor and transformer applications at low frequencies.

Résumé :

Polycrystalline mixed-phase TiO2nanofibers embedded with 2.0% w/v Ag nanoparticles was prepared by the electrospinning technique. Calcination of dry Ag nanoparticles-titanium (IV) isopropoxide/PVP electrospun nanofiber mats in air at for 24 h yielded polycrystalline TiO2/Ag nanofibers. The morphology and distribution of silver nanoparticles were observed by transmission electron microscopy (TEM), scanning TEM (STEM), and high-angle annular dark-field (HAADF) imaging. Mixed-phase anatase and rutile TiO2nanofibers were produced with Ag nanoparticles. High-resolution TEM lattice-fringe measurements showed good agreement with Ag (111), anatase (101), and rutile (110) phases. The photocatalytic activity of TiO2/Ag nanofibers was compared to the photocatalytic activity of pure TiO2nanofibers by studying the photodegradation of methyl red dye under UV light irradiation, in a photoreactor. UV-visible absorbance spectra showed that the rate of decay of the dye in case of photodegradation by TiO2/Ag nanofibers was 10.3 times higher than that by pure TiO2nanofibers. The retaining of the fiber morphology along with the increased surface area due to the addition of Ag nanoparticles can be believed to enhance the photocatalytic oxidation of methyl red dye.

Résumé :

Purpose. To assess the effect of a self-paced walking intervention within a topographically varied outdoor environment on physiological and perceptual markers in cardiac rehabilitation (CR) patients.Methods. Sixteen phase II CR patients completed twelve self-paced one-mile walking sessions over a four-week period within a community-based CR programme. Walking velocity, heart rate (HR), and ratings of perceived exertion (RPE) were reported at eight stages throughout the self-paced walks.Results. The study showed a significant increase in walking velocity from week 1 (~4.5 km/h) to week 4 (~5.1 km/h) of the self-paced walking programme (P<.05). A significantly higher HR was also observed in week 4 (111±13 b·min−1;~69% of maximal HR) compared to week 1 (106±14 b·min−1;~65% of maximal HR,P<.001). There were no changes in the average RPE across the course of the 4-week self-paced walking programme (P>.05).Conclusion. A self-paced walking programme may elicit an appropriate training stimulus for CR patients when exercising within a diverse topographical environment. Participants completed a one-mile walk within a shorter period of time and at a higher physiological intensity than that elicited at the onset of the programme, despite no observed changes in participants' subjective perception of exertion.

Résumé :

The rate of potassium (K) release from soils is a dynamic process, and it is important to the evaluation of soil K availability to plant. The objectives of this study were to determine K release characteristics and the correlation of these parameters with bean plant indices in surface soils of 15 calcareous soils. The kinetics of K release was determined by successive extraction with 0.01 mol/L CaCl2 in a period of 2–2017 h at 25 ± 1°C. The results showed that the cumulative K&rlm; release ranged from 111 to 411 mg/kg. A plot of cumulative amount of K released showed a discontinuity in slope at 168 h. Thus, two equations were applied to segments of the total reaction time (2 to 168 and 168 to 2017 h). The amounts of K released during 2–168 and 168–2017 h ranged from 55 to 299 and 44 to 119 mg/kg, respectively. Release kinetics of K conformed fairly well to parabolic diffusion, simplified Elovich and power function models in two segments. Potassium released after 2–168 and 168–2017 h and K release rate constants were significantly correlated (P < 0.05) with bean plant indices, while correlation between K extracted by using 1 mol/L NH4OAc (ammonium acetate) and plant indices was not significant. The results of this research showed that information obtained from K release studies in laboratory and kinetics equation parameters can help to estimate the K supplying power of soils.

Résumé :

We report on structural and electronic properties of two-dimensional materials ob-tained by analytical low-voltage aberration-corrected transmission electron microscopy. Basic crystallographic defects and their peculiarities will be discussed for two-dimensional materials at the atomic level. Thus, we report the atomic structure of point defect and -clusters [1], the full life circle of dislocations [2] and the movements of grain boundaries in grapheme [3]. In addition, we unravel the atomic structure of the amorphous phase (graphene, SiO2) in direct space just from single-atom-based analysis of high-resolution TEM images [5, 6]. As the energetic electron beam is interacting with the specimen via transferring energy to the atoms, structural transformation between different phases can be followed atom-by-atom [7, 8, 9]. In addition, physical properties such as the knock-on damage threshold is determined from controlled direct space experiments and precise measurements of high-resolution TEM images of graphene and MoS2[8, 7]. However beam-electron interactions with the specimen are also restricting imaging the pristine structure of a sample. It can be suppressed by simply limiting the total electron doses on the samples. Limited electron doses, however, result in worse signal to noise ratios. Here, a quantitative approach for estimating the visibility of objects in TEM images with limited doses will be presented [10]. Another traditional approach to suppress electron-induced damage during HRTEM observation is to employ an efficient cleaning procedure [11] and the protective coating of sensitive materials. This old approach will be taken to its extreme, when radiation sensitive materials are enclosed inside carbon nanotubes [12] and between two graphene layers [13]. We show moreover the advantage of lowering the accelerating voltage for imaging the pristine structure of low-dimensional materials [14]. [4] P. Wachsmuth, R. Hambach, M.K. Kinyanjui, et al., Phys.

Résumé :

Titanium and titanium dioxide thin films were deposited onto Si(111) substrates by magnetron sputtering from a metallic Ti target in a reactive Ar+O2atmosphere, the composition of which was controlled by precision gas controllers. For some samples, 1/3 of the surface was covered with palladium using molecular beam epitaxy. Chemical composition, density, and layer thickness of the layers were determined by Auger electron spectroscopy (AES) and Rutherford backscattering spectrometry (RBS). The surface morphology was studied using high-resolution scanning electron microscopy (HRSEM). After deposition, smooth, homogenous sample surfaces were observed. Hydrogen charging for 5 hours under pressure of 1 bar and at temperature of 300°C results in granulation of the surface. Hydrogen depth profile was determined using secondary ion mass spectrometry (SIMS) and nuclear Reaction Analysis (N-15 method), using a15N beam at and above the resonance energy of 6.417 MeV. NRA measurements proved a higher hydrogen concentration in samples with partially covered top layers, than in samples without palladium. The highest value of H concentration after charging was about 50% (in the palladium-covered part) and about 40% in titanium that was not covered by Pd. These values are in good agreement with the results of SIMS measurements.

Résumé :

Monitoring the population iodine status is essential for iodine deficiency eradication. This study assessed the average dietary iodine intake and the iodine status of a random sample of the Italian general adult population. The study population included 2378 adults aged 35–79 years (1229 men and 1149 women) from all 20 Italian regions, participating in the Osservatorio Epidemiologico Cardiovascolare/Health Examination Survey 2008–2012 (OEC/HES), and were examined for iodine intake in the framework of the MINISAL-GIRCSI Programme. Dietary iodine intake was assessed by the measurement of 24 h urinary iodine excretion. The median daily iodine intake of the whole population was lower (96 µg/d, interquartile range 51–165) than the daily adequate iodine intake according to both EFSA and WHO recommendation (150 µg/d), with a significantly lower value among women (85 µg/d) compared with men (111 µg/d). Iodine intake diminished with age and increased with BMI (body mass index) in male but not in female participants, without achieving the adequate intake in any sex, age, or BMI category. In this random sample of Italian general adult population examined in 2008–2012, iodine intake still remained lower than the recommended values despite the implementation of a strategy of iodoprophylaxis based on salt iodization in 2005. These data represent a valuable reference for future monitoring of iodine status in our country.

Résumé :

By the end of 2012 the population of motorcycle reached 77.7 million units with their average composition on the road reached 82%. The number of motorcycles produce CO2 emissions which have a negative impact on global warming. Global warming occurs because the greenhouse effect of CO2 in the atmosphere absorb heat energy and obstructed the heat from the atmosphere to the higher surface.The data collected in this research is the data of motorcycles fuel consumption. The method of data processing by converting the fuel consumption data to CO2 emissions using the equation of the Clean Development Mechanism (CDM) AMS-III Methology. The purpose of this research is to create models of CO2 emissions on a motorcycle against several influential independent variables such as manufacture, service life, engine displacement (cc) and travel speed. Method analysis using correlation and regression analysis.Based on the regression analysis, the best combination that produces the lowest value of CO2 is a motorcycle with a combination of manufacture number 2, 5 years service life, engine displacement of 111-149 cc and travel speed of 60 km/h. Whereas from the the correlations analysis obtained the motorcycle of manufacture number 2 able to decrease up to 15% CO2 and motorcycles with engine displacement of 111-149 cc is able to reduce CO2 emission from 17% to 43%. While the service life of one year to six years resulting CO2 emissions which relatively similar with only difference of 15%. Furthermore, the travel speed of 60 km/h able to reduce CO2 emissions by up to 62%.

The text presents differences between the mechanism of seeing and recording images and potential sources of errors in color reproduction in recorded images. The measurements show that despite the relatively high values of indices (Ra, Rf i Rg) not all tested lamps are suitable for use on a photo set, as indicated by the value of TLCI index. The lighting requirements on a film set prioritize the quality of color reproduction, even at the expense of reducing the Luminous efficacy of a source (LES ) value. Full Text: PDF ReferencesL.T.

Résumé :

Over the last years, Kelvin probe techniques have found a more and more widespread application in corrosion science. While the pioneering applications by Stratmann et al were focused on investigating corrosion underneath ultra-thin electrolyte layers to cathodic delamination of organic coatings [1, 2], over the last 15 years the Kelvin probe method was shown to be applicable for new applications such as mapping hydrogen activities, measuring hydrogen permeation [3] and even measuring oxygen reduction at buried interfaces [4] or on surfaces just covered by a monolayer of water [5]. In this contribution examples about the latest developments of its application in corrosion science will be presented, from coating delamination to hydrogen in materials. [1] M. Stratmann, H.

Résumé :

There is insufficient data regarding antimicrobial stewardship (AS) and outcomes of very low birth weight (VLBW) neonates after AS programs. This observational, retrospective study addressed AS and outcomes of VLBW neonates admitted to an Italian level-three center. Two periods were compared: (i) baseline, before AS (January 2011–December 2012) and (ii) intervention, after AS (January 2016–December 2017). Between these two periods, procedures were put in place to inform medical and nursing staff regarding AS. There were 111 and 119 VLBW neonates in the baseline (6744 live births) and in the intervention period (5902 live births), respectively. The number of infants exposed to antibiotics (70%) during the hospital stay did not change, but the total days of therapy (DOT, median 12 vs. 5) and DOT/1000 patient days (302 vs. 215) decreased in the intervention period (p < 0.01), as well as the median duration of first antibiotic treatment (144 vs. 48 h, p < 0.01). A re-analysis of single cases of culture-proven or culture-negative sepsis failed to demonstrate any association between deaths and a delay or insufficient antibiotic use in the intervention period. In conclusion, AS is feasible in preterm VLBW neonates and antibiotic use can be safely reduced.

Résumé :

Background: Peanut component tests (PCT) have become important in the evaluation of peanut allergy. There remains a paucity of research across the United States in investigating the utility of PCT in clinical practice in conjunction with current standards of care. Objective: The primary aims were to evaluate the performance and sensitization patterns of PCT in clinical practice when first available at our institution. Methods: We performed a retrospective chart review of 184 children with PCT and oral food challenge (OFC) results between 2012 and 2017. Simple logistic regression models assessed the associations between PCT and OFC outcomes. Receiver operator characteristic curves were constructed, and a predicted probability curve was derived for Ara h2. Results: The median (interquartile range [IQR]) age at OFC was 4 years (2‐7 years), and 111 patients (60%) were boys. Ara h 2 was the most commonly sensitized PCT. Sixty-one patients (33%) reacted at OFC. Ara h 2 specific immunoglobulin E (sIgE) ≥ 0.35 kUA/L was associated with increased odds of reacting at OFC (odds ratio 5.91 95% confidence interval, 2.93‐11.89; p < 0.001); however, 19 patients (37%) positive for Ara h 2 did not react. Ara h 2 sIgE of 0.49 kUA/L and 4.58 kUA/L were associated with 50% and 90% probability, respectively, of reacting at OFC. Among those sensitized only to Ara h 8 or 9 (n = 21), 86% had no reaction. There was no statistically significant association with polysensitization to Ara h 1, 2, and 3, and peanut OFC outcome. Conclusion: Although the Ara h 2 sIgE value was associated with clinical reactivity, a significant proportion of the patients sensitized to Ara h 2 tolerated peanut. OFC remains an important tool in the evaluation of peanut allergy.

Résumé :

The crude hydroalcoholic extract of Cassia sophera Linn. leaves were investigated for its possible analgesic and antipyretic activities in rodents. The peripheral analgesic activity of C. sophera leaves was studied using acetic acidinduced writhing in mice and central analgesic activity was evaluated by using heat-induced pain in mice. The antipyretic activity of HECS was studied in Brewers yeast-induced pyrexia in rats. All these experiments were done at the doses of 300 and 600 mg/kg body weight. Intraperitoneal administration of C. sophera hydroalcoholic extract (HECS) produced significant (P<0.01) reduction in number of writhing induced by acetic-acid. Moreover, in hotplate test, HECS significantly (P<0.01) raised the pain threshold at different time of observation (0-180 min) in comparison with control. The extract also showed significant as well as dose-dependent antipyretic activity in Brewers yeast-induced pyrexia in rats throughout the observation period of 4 h.

Résumé :

The crude methanolic extract, ethyl acetate and butanolic fractions, tannins, saponins and polysaccharides of the marine brown alga, Padina pavonica, growing on the Algerian Mediterranean Coast were measured for antioxidant activity, using total antioxidant capacity (TAC), reducing power and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. Total phenolic, flavonoid and proanthocyanidin contents were determined. The total phenolic, proanthocyanidin and flavonoid contents of methanolic extract were about of 2.007 ± 0.104 mg GAE/g DM, 4.611 ± 0.346 mg CE/g DM and 1.132 ± 0.091 mg CE/g DM, respectively. The total antioxidant capacity was higher (4.365 ± 0.452 mg AAE/g DM) in crude methanolic extract. For the other two tests, the tannins and ethyl acetate fraction presented high activities compared to the other extracts with EC50 about 1.430 ± 0.000 and 1.615 ± 0.009 mg/mL), respectively for the reducing power and 5.718 ± 1.111 and 5.848 ± 0.186 mg/mL for the DPPH radical scavenging. The seaweed extracts displayed moderate antioxidant activity compared to ascorbic acid.

Résumé :

The development of battery systems fabricated from abundant materials that meet the highest safety requirements is a major challenge, while the demand for efficient energy storage is continuously increasing.[1] Sodium metal batteries might be an adequate substitute for lithium-ion batteries. In comparison to lithium, sodium is more abundant, is a strong reducing agent, and has a less negative standard electrode potential.[2] Investigations of the deposition and the dissolution behavior of sodium are of utmost importance since dendritic growth is amongst the key factors limiting the lifetime and safety of sodium metal batteries.[3] In-situ scanning tunneling microscopy (STM) combined with cyclic voltammetry allows observing topographical changes in real-time and to determine potential regions of related electrochemical processes. Single-crystal surfaces are commonly used in fundamental studies of metal deposition due to their (i) well-defined structure, (ii) ease and reproducibility of preparation, and (iii) stability in the electrochemical environment.[4] However, metallic sodium is extremely reactive. In particular, Na reacts violently with water and molecules containing acidic hydrogen atoms, but even with commonly used battery electrolytes as organic carbonates.[5] Fortuitously, ionic liquids (ILs) are promising solvents in sodium metal batteries.[6] Due to their unique properties, they are appropriate for preparing electrolytes in investigations of the deposition and dissolution behaviour of metals. They are known for their relatively wide electrochemical stability windows for both sodium and lithium deposition, as well as for low diffusion rates, which facilitate real-time deposition studies.[7] In this work, the initial stages of sodium underpotential deposition (UPD) onto a Au(111) electrode surface from the ionic liquid N-methyl-N-propylpiperidinium bis(trifluoromethanesulfonyl)imide ([MPPip][TFSI]) is investigated using in-situ STM and classical electrochemical measurements. Four subsequent stages in the UPD process of sodium on Au(111) can be discerned. (i) Nucleation of sodium starts around 1.1 V vs. Na/Na+ at the so-called elbows of the reconstructed Au(111) surface. (ii) Small mono-atomically high islands grow around the nuclei at a slightly more negative electrode potential of 1.0 V. (iii) The islands slowly coalesce into smooth layers after lowering the potential to 0.5 V (Figure 1), resulting in several clusters with defined steps. (iv) More islands grow on top of the existing layer and the preferred deposition mode changes from smooth layer formation to 3D-growth, resulting in cauliflower-like structures, especially at the step edges of the clusters. The deposition of several layers of sodium in the UPD regime can be explained by the alloy formation of sodium and sodiophilic gold.[8] It is worth mentioning that this deposition behaviour shows several similarities to that of lithium UPD on Au from ILs, including island formation and multiple layer growth.[7,9] So far, nucleation at the reconstruction elbows has not been reported for lithium, but it has already been observed during deposition of other metals such as nickel, cobalt, and palladium both for electrodeposition[10] and under UHV conditions.[11,12] References [1] B.

Résumé :

A preliminary study to determine the group of compound contained in the ethanolic extract of mahagony (Swietenia mahagoni L. Jacq.) seeds and its inhibitory activity to a-glucosidase enzyme has been done. The information from this study will be used in the further investigation about the specific constituents related to the bioactivity. The seed was grounded and then extracted with ethanol by maceration technique. The crude extract was separated with liquid-liquid extraction by using n-hexane, ethyl acetate, and methanol as the solvents. The best eluent for isolation, chloroform:ethanol (1:1), was determined by thin layer chromatography while alumina as stationary phase. The isolation step with column chromatography gave two types of isolates, yellow and colorless isolate. In order to get information about the compound, the crude extract was subjected to phytochemical assignment and the isolate with the better activity was analyzed by infrared spectroscopy. The inhibitory activity for the yellow isolate with IC50 as 19.345 ppm was better than the colorless isolate. Therefore, the IR spectroscopy assay was subjected to the yellow isolate. Based on the comparison IR spectra with literatures, it has suggested that the yellow isolate contains tetranortriterpenoid or limonoid group.Keywords: Swietenia mahagoni L.

Résumé :

The spontaneous surface alloying during deposition is an unexplored route for developing new materials with a great potential for applications in catalysis, electronics, sensing and photonics. Although the surface-stress driven alloying has been theoretically predicted and explored on a fundamental level in the Ultra High Vacuum (UHV)1, very little of that knowledge has been employed in practice. The electrochemically controlled surface-alloying has not been understood well, although it was reported in many systems. The formation of UPD monolayer in the presence of specifically adsorbing ions is often accompanied by competitive adsorption, changes of the kinetics and energetics of nucleation and growth, and the co-adsorption that could stabilise new stages and phases of growth2,3. The effect of anion adsorption on surface alloying kinetics and energetics can significantly affect alloys’ properties and their (electro)chemical reactivity. Here in this work, we focused on systems, Pb UPD on Au(111) and Pb UPD on Cu(100), in which surface alloying has been reported in the past4-8. Pb UPD on Au(111) in perchlorate solution has been a well-studied system by a range of surface techniques4,5. However, very little is known about the effect of halide adsorption in this system. In the perchlorate solutions, in-situ surface stress relaxation4,5 and the in-situ STM4 surface changes unambiguously demonstrated changes associated with the surface alloying. Pb UPD on Cu(100) is another system where the formation of Pb3Cu4 ordered surface alloy is reported and shown to self-assemble in the nanoribbons pattern in the presence of chloride6-8. The studies on those UPD systems aimed to understand the effect of strong halides adsorption (chloride and bromide) on the electrochemical behaviour and surface alloying. Both chloride and bromide form well-ordered anion adlayers on Au and Cu while they differ in the strength of their interaction with the substrate and UPD metal layer. The studies included the electrochemical methods such as the polarisation at fixed sub-ML coverages of Pb over an extended period and following the changes in electrochemical behaviour. In addition to that, we investigated some of the structural and compositional changes by surface techniques such as X-ray Photoelectron Spectroscopy (XPS), Ultraviolet Photoelectron Spectroscopy (UPS) Energy-Filtered Photoemission Electron Microscopy (EF-PEEM) and Work Function (WF) mapping9.

Résumé :

We synthesized silver nanoparticles of different sizes and forms as function of the molar masses of AgNO3, in two different solvent mediums (ethanol, methanol). We carried out the synthesis according to standard chemical route with major modifications. The spectroscopic characterization showed the presence of two distinct absorption bands; the first band at 300 nm and the second shifted to 440 nm. We found a multipolar phenomenon depending on the temperature. The shape and size predicted by the numerical model are conform to the experimental results. The study demonstrated that the nanoparticles have a spheroidal shape.

Résumé :

We present the temperature dependent elastic and ultrasonic properties of sodium borohydride. The second and third order elastic constants of NaBH4 have been computed in the temperature range 0-300K using Coulomb and Born-Mayer potential. The sodium borohydride crystallizes into NaCl-type structure. The computed values of second order elastic constants have been applied to evaluate the temperature dependent mechanical properties such as bulk modulus, shear modulus, tetragonal modulus, Poisson’s ratio and Zener anisotropy factor and ultrasonic velocity to predict futuristic information about sodium borohydride. The fracture to toughness ratio (bulk modulus/shear modulus) in sodium borohydride varied from 1.91 to 1.62, which shows its behavioral change from ductile to brittle on increasing the temperature. Then, ultrasonic Grüneisen parameters have been computed with the use of elastic constants in the temperature regime 100-300K. The obtained results have been discussed in correlation with available experimental and theoretical results. [1] A. Amudhavalli, M. Manikandan, A. Jemmy Cinthia, R. Rajeswarapalanichamy and K.

Résumé :

In recent years, Ge has emerged as one of the most promising materials toward next-generation high-performance and low-power-consumption optoelectronic devices. Moreover, SiGe/Ge heterostructures, consisting of strained SiGe with high Ge contents and Ge, have high potential for various applications. In terms of crystal orientations, there are various attractive choices for Ge and Ge-rich SiGe differently from Si. Particularly, the (111) orientation is very attractive for spintronics applications owing to capability of lattice matched epitaxial growth of high-quality ferromagnetic materials on the Ge(111) and SiGe(111). To create the SiGe/Ge heterostructures on the Si substrate, high quality Ge virtual substrates firstly have to be formed on the Si. The so-called Ge-on-Si is simple but very important templates for various applications, such as Ge-MOSFETs, LEDs, LDs, photo detectors, micro structures and Ge-on-Insulator (GOI) wafers etc. Especially the tensile strain induced in the Ge due to the thermal mismatch between the Ge and Si plays very important roles. For example, very efficient light emission can be obtained through strain-induced Γ-valley shift and resultant increase in the direct transition probabilities. We fabricated both Ge-on-Si(100) and Ge-on-Si(111) p-i-n LEDs and strong room-temperature EL emissions were obtained [1]. Epitaxial growth of the high quality strained SiGe on the Ge-on-Si is the most important for strain engineering of SiGe/Ge heterostrucutures. As the growth of the strained layer is limited by the critical thickness, we systematically investigated the critical thickness of the strained SiGe and clarified that it depends on the crystal orientations [2]. It was also shown that the critical thickness is markedly reduced when grown on the Ge-on-Si compared to the Ge substrate due to dislocations in the Ge-on-Si. We proposed to grow the SiGe on the Ge-on-Si on which the mesa patterning is performed. As a result, the critical thickness is drastically increased owing to the suppression of defect generation and propagation [3]. This patterning method enables us to increase the strained layer thickness and highly widen potential applicabilities of the strained SiGe/Ge heterostructures. One of the attractive applications is strained SiGe/Ge multi quantum wells (MQWs). We obtained strong roome temperature light emissions from the relatively thick MQWs formed on the Ge-on-Si (111) and Si(100) with patterning. Based on the Ge-on-Si, the larger tensile strain can be induced by the fabrication of microbridge structures, where the freestanding Ge is realized and elastic tensile stress is applied to the narrow microbridge area via the local strain relaxation of large pad areas sandwiching the bridge. In many reports, standard Si(100) substrates have been used with the bridge direction set to be <001> direction, whereas the Γ-valley shift via the tensile strain is expected to be the largest with the <111> directional uniaxial strain [4]. We attempt to fabricate the Ge microbridge along the <111> direction on the Ge-on-Si(110) substrate and very strong room-temperature PL was obtained. Moreover, when microbridge side walls are formed vertical, the generated light is well reflected by the side walls and very strong resonant light emissions are observed. Technically, the selective wet-etching of the underlying Si of the Ge-on-Si is a key process of importance to fabricate completely freestanding structures. As the crystal orientation highly affects the etching rate, a choice of the orientation is very important. Additionally, we are attempting other fabrication methods. One is making many holes in the pad areas, which enables to enhance the under-etching. Use of Ge-on-SOI or Ge-on-Insulator (GOI) substrates is another way to facilitate the under-etching as the buried oxide can be easily removed by the fast etching. Moreover, we show recent results on SiGe/Ge heterostructure imbedded microbridge, where the light emission wavelength becomes controllable and emission efficiency can be enhanced owing to the strain and band engineering.

Résumé :

Background: There are wide variations in antibiotic use in neonatal intensive care units (NICUs). Limited data are available on antimicrobial stewardship (AS) programs and long-term maintenance of AS interventions in preterm very-low-birth-weight (VLBW) infants. Methods: We extended a single-centre observational study carried out in an Italian NICU. Three periods were compared: I. “baseline” (2011–2012), II. “intervention” (2016–2017), and III. “maintenance” (2020–2021). Intensive training of medical and nursing staff on AS occurred between periods I and II. AS protocols and algorithms were maintained and implemented between periods II and III. Results: There were 111, 119, and 100 VLBW infants in periods I, II, and III, respectively. In the “intervention period”, there was a reduction in antibiotic use, reported as days of antibiotic therapy per 1000 patient days (215 vs. 302, p < 0.01). In the “maintenance period”, the number of culture-proven sepsis increased. Nevertheless, antibiotic exposure of uninfected VLBW infants was lower, while no sepsis-related deaths occurred. Our restriction was mostly directed at shortening antibiotic regimens with a policy of 48 h rule-out sepsis (median days of early empiric antibiotics: 6 vs. 3 vs. 2 in periods I, II, and III, respectively, p < 0.001). Moreover, antibiotics administered for so-called culture-negative sepsis were reduced (22% vs. 11% vs. 6%, p = 0.002), especially in infants with a birth weight between 1000 and 1499 g. Conclusions: AS is feasible in preterm VLBW infants, and antibiotic use can be safely reduced. AS interventions, namely, the shortening of antibiotic courses in uninfected infants, can be sustained over time with periodic clinical audits and daily discussion of antimicrobial therapies among staff members.

Résumé :

Introduction Neuromuscular electrical stimulation (NMES) is used in athletes to enhance muscle strength (Filipovic et al., 2012) or in patients to restore muscle strength (Nussbaum et al., 2017). The increased maximal voluntary contraction (MVC) torque of one limb (e.g. right leg) while transcutaneous NMES is concomitantly applied to the contralateral limb (e.g. left leg) has been termed contralateral facilitation. This effect has previously been reported for the knee extensors (Cattagni et al., 2018; Minetto et al., 2018) but the underlying mechanisms remain to be investigated. It is also not known whether or not other muscle groups may show contralateral facilitation. The aim of this study was to compare plantar flexor contralateral facilitation between a submaximal voluntary contraction (~10% MVC torque) and two evoked contractions with presumably distinct motor unit recruitment patterns (conventional and wide-pulse high-frequency [WPHF] NMES; Bergquist et al., 2011) of the ipsilateral plantar flexors, with respect to a resting condition. Methods Twenty-two healthy volunteers (4 women: mean ± SD, 26 ±4 yrs, 162 ±7 cm, 65 ±9 kg and 18 men: 26 ±6 yrs, 180 ±5 cm, 76 ±6 kg) took part to the experiments. Contralateral MVC torque and maximal voluntary activation level were measured in 4 different conditions: while the ipsilateral plantar flexors were at rest, voluntarily contracted at 10% of MVC torque or stimulated with conventional (0.1 ms, 30 Hz) and wide-pulse high frequency (1 ms, 100 Hz) NMES for 15 s at a pre-determined intensity to evoke 10% of MVC torque. Additional neurophysiological parameters (soleus H-reflex and V-wave amplitude and tibialis anterior coactivation level) were quantified in a subgroup of 12 participants (4 women and 8 men). Results Conventional and WPHF NMES of the ipsilateral plantar flexors did not induce any contralateral facilitation of MVC torque with respect to the resting condition (respectively: mean ± SD, 133 ±44, 133 ±43 and 135 ±39 Nm) as well as maximal voluntary activation level, while an ipsilateral voluntary contraction of the same intensity resulted in lower contralateral strength than conventional NMES. Moreover, no alteration in the neurophysiological parameters was observed in the different conditions. Discussion/Conclusion The absence of contralateral facilitation contrasts with the results obtained on the knee extensors and can be attributed to the absence of neural changes observed on the contralateral side. These findings should be considered by clinicians/researchers in lower limb rehabilitation settings, as it seems easier to induce contralateral facilitation in proximal vs. distal lower limbs.

Résumé :

Numerical literacy is the ability needed to use number ideas and arithmetic skills in everyday situations as well as the ability to analyze quantitative data around children. This study aims to determine the effect of the intervention of singing favorite food songs on children's numerical literacy. Using a pretest-posttest experimental design with a control group, this study involved 20 children as research objects, consisting of 10 experimental class children and 10 control class children. The results of the study showed that singing activities with the theme of favorite food influenced the numerical literacy of kindergarten children. This singing activity attracts children's interest, thus showing a significant difference between the experimental class and the control class. Therefore, for further research, it is suggested that early childhood educators can always take advantage of artistic activities such as singing to attract children's interest in any learning.

Résumé :

Los imaginarios sociales son entendidos como aquellas construcciones mentales socialmente compartidas y encarnadas en las instituciones sociales, por lo cual surge el interés de develar aquéllos que son construidos en torno al territorio y a las fronteras imaginarias al interior de la Comuna 10 de Pasto. Esta investigación se desarrolló con base en el paradigma cualitativo con enfoque fenomenológico, usando técnicas de recolección de información como el grupo de discusión y el grupo focal. Entre los principales resultados se encontró que los imaginarios sociales instituyentes están relacionados con concepciones como la territorialidad, la muerte, el conflicto intergeneracional, el honor, la familia y la lealtad, mientras que los instituidos se forman por el control territorial y los micropoderes, todo lo cual influye en la consolidación de fronteras imaginarias, medios de subsistencia y marco representacional de la violencia urbana en el devenir de los micropoderes en la Comuna 10.

Résumé :

Language skills are significant predictors of early academic and social-emotional outcomes of children and are important predictors of school readiness. This study aims to improve children's language skills through the application of mind mapping learning methods. This classroom action research used Kemmis and Taggart's cycle model. The research subjects were 12 children in group B consisting of eight boys and four girls. The data was collected through observation, interviews, and documentation with the validity of the data using source triangulation and method triangulation. This research uses data analysis techniques in the form of data condensation, data presentation, and drawing conclusions. The results showed that the children's language skills through the application of the mind mapping method in the first cycle were 75%, and in the second cycle had increased to 92%. Based on the results of teacher observations in the implementation of cycle I, the children's language skills obtained a percentage value of 61.5%, and in cycle II increased to 92.3%. While the results of observations of children's activities in the implementation of the first cycle obtained a percentage of 54%, and in the second cycle, it increased to 85%. This study found that the teacher's assessment of this mind mapping method was an easy method to understand so that it was easy to apply in classroom learning. The implication of this research is that it is necessary to carry out further research on the application of the mind mapping method for other aspects of development.

Résumé :

Knowledge about clean and healthy life in children needs to be given early to shape behavior in everyday life. Knowledge about healthy living can be provided at school through various learning programs. This study aims to find the effectiveness of health promotion programs (JUMSIH) to increase children's knowledge about clean and healthy living. The research method is a pre-experimental one-shot case study design. The respondents of this study were 68 students aged 7-8 years. The results showed that the JUMSIH program can help children have knowledge about healthy living. Based on data analysis, n = 15 generally obtained scores above 2.6. It was concluded that healthy living skills are often performed by students such as hand washing, bathing, and toothbrush behavior which are basic skills for children to be able to live healthy lives. Suggestions for further research which is the development of various programs to increase awareness of clean and healthy living from an early age.

Résumé :

Cellulose is the main raw material for the production of paper. Companies that produce it present in their production line the cutting of the cellulose sheet. This failure is sporadic and has a high economic impact since it paralyzes the production line for several hours, incurring unproductive hours and a large deployment of human and financial resources. In this research, the use of Data Mining is proposed to define a machine learning algorithm that allows predicting the cutting of the cellulose sheet in a production line of a cellulose plant in Chile. The results show that by applying this technique it is possible to predict the cutting of the cellulose sheet well in advance to take corrective actions to avoid cutting and thus minimize the economic impact associated with the failure.

Résumé :

BL13-XALOC is currently the only macromolecular crystallography beamline at the 3 GeV ALBA synchrotron near Barcelona, Spain. The optics design is based on an in-vacuum undulator, a Si(111) channel-cut crystal monochromator and a pair of KB mirrors. It allows three main operation modes: a focused configuration, where both mirrors can focus the beam at the sample position to 52 µm × 5.5 µm FWHM (H × V); a defocused configuration that can match the size of the beam to the dimensions of the crystals or to focus the beam at the detector; and an unfocused configuration, where one or both mirrors are removed from the photon beam path. To achieve a uniform defocused beam, the slope errors of the mirrors were reduced down to 55 nrad RMS by employing a novel method that has been developed at the ALBA high-accuracy metrology laboratory. Thorough commissioning with X-ray beam and user operation has demonstrated an excellent energy and spatial stability of the beamline. The end-station includes a high-accuracy single-axis diffractometer, a removable mini-kappa stage, an automated sample-mounting robot and a photon-counting detector that allows shutterless operation. The positioning tables of the diffractometer and the detector are based on a novel and highly stable design. This equipment, together with the operation flexibility of the beamline, allows a large variety of types of crystals to be tackled, from medium-sized crystals with large unit-cell parameters to microcrystals. Several examples of data collections measured during beamline commissioning are described. The beamline started user operation on 18 July 2012.

ABSTRACT This study aims to investigate the influence of internal (Third Party Funds (TPF), Asset Quality, Operational Efficiency) and external (Inflation, interest rates, exchange rates) on the liquidity of Islamic commercial banks in Indonesia. Data collected annually from 2014-2019 to be tested to see the effect of using panel data regression analysis techniques by utilizing Eviews 10. The sampling technique used purposive sampling and obtained a sample of 11 Islamic Commercial Banks in Indonesia. Based on the panel data regression test, the selected model is random effect and proves the relationship: TPF and interest rates have a positive and significant relationship to liquidity. inflation and exchange rate have a negative and significant relationship to liquidity. asset quality and operational efficiency have no significant effect on liquidity. Meanwhile, the simultaneous test proves that internal and external factors affect liquidity. This research is expected to be used as a reference by Islamic banks in managing their funds optimally and applying the precautionary principle, especially when distributing financing to customers so that there is no risk of financing and causing liquidity problems.

Résumé :

In this study, the interactions between H atoms and the (100), (110), and (111) surfaces of platinum have been investigated by using the London-Eyring-Polanyi-Sato (LEPS) potential function. The adsorption zones (sites) and LEPS energy values of these sites have been determined theoretically. In addition, the potential-energy surfaces for each Pt surface have been obtained in detail. Further, the adsorption sites on the surface, scattering from the surface, diffusion paths on the surface, and transition regions to the subsurface, have been determined and the differences have been examined in detail among the surfaces. From these results, it is found that an H atom has the lowest binding energy at the hollow sites on the Pt (100) and Pt (111) surfaces and that it has the lowest binding energy at the long-bridge sites on the Pt (110) surface. It has also been determined that the hollow sites on the three surfaces are the regions through which H atoms can penetrate into the subsurface. In addition, it has also been found that, for each of the three Pt surfaces, the diffusion of an H atom across the surface may follow a bridge-hollow-bridge pathway. These results are in agreement with previous experimental and theoretical results. Besides, the adsorption and diffusion manners of hydrogen atoms on each of the Pt surfaces have been analyzed deeply.

Résumé :

Introduction: The objective of the study was to reduce, by a bundle of interventions, the global bloodstream infections and catheterrelated bloodstream infections rates in neutropenic hematology patients with a long-term central venous catheter. Material and Methods: This was a non-randomized prospective study. It was conducted in a 20-bed hematology oncology unit (Portuguese Institute of Oncology, Porto, Portugal) between 1st of August 2010 and 31st of January 2012. In this period we introduced a bundle of interventions (study group) and compared the results with the six months prior to implementation (control group). The interventions consisted in the use of a neutral pressure mechanical valve connector instead of a positive pressure mechanical valve connector, a more frequent change of this connector and a more efficient clean solution. One hundred and sixteen hematology patients with a long-term central venous catheter at time superior of 72 h, with 8 867 central venous catheter days [6 756 central venous catheter days in the study group and 2 111 central venous catheter days in the control group] were included in the study. Results: A significant reduction in bloodstream infections rates and catheter-related bloodstream infections rates was achieved. Bloodstream infections rates: [32.69 (control group) vs. 9.43 (study group)], incidence reduction 71% [relative risk 0.2886, CI 95% (0.1793 – 0.4647), p < 0.001] and catheter-related bloodstream infections rates: [17.53 (control group) vs. 4.73 (study group)], incidence reduction 71% [relative risk 0.2936, CI 95% (0.1793 – 0.5615), p < 0.014]. No significant difference (p > 0.05) was found in the neutrophil count at the time of blood culture samples between groups: 69% (< 500 neutrophils/mm3) [71% (study group) vs. 68% (control group)]. Conclusions: The introduction of this bundle of interventions based on the variables of patient, product and practice, supported by the Healthcare and Technology Synergy framework, quickly resulted in a significant reduction of bloodstream infections and catheterrelated bloodstream infections rates.

Résumé :

Sol-gel electrochemistry has gained great popularity in the past decades, mostly because of the ease of formation of silica and organosilica films with tailor-made properties that can be advantageously exploited for several applications when coated on a suitable electrode surface. In particular, silica-based materials displaying a regular structure at the mesoporous level have been found to be very promising electrode modifiers [1-3] because they ensure fast mass transport processes [4], which are often rate-determining in electrochemistry. In this context, an original electrochemical method has been developed to indirectly generate sol-gel-derived (organo)silica thin films, with promising applications in the field of bioelectrochemistry and sensors and beyond. After a brief introduction to the field, this lecture will present the concept the electrochemically-assisted generation of sol-gel films [5], its interest for bioencapsulation and elaboration of electrochemical bioreactors [6-9], its suitability to get nanostructured electrode surfaces with preferential pore orientation [3,10,11], including their modification with organo-functional groups [3,12,13] and their permselective properties [14-16], and will end with promising applications in electroanalysis and sensors [17-20], electrocatalysis [20,21], energy storage [22] or electrochromism [23].

Résumé :

Playing curriculum development based on early childhood learning is a major issue in international early childhood education discussions. This study aims to look at the concepts and practices of play-based curriculum in early childhood education institutions. The study uses qualitative methods with the CIPP model program evaluation on play-based curriculum. Data collection techniqueswere carriedout using participatory observation, document studies and interviews. Participants are early childhood educators, early childhood and parents. The results found that the play-based curriculum has not yet become the main note in the preparation and development of concepts and learning practices in early childhood. Play-based curriculum quality standards have not provided a solid and clear concept foundation in placing play in the center of learning models. Other findings the institution has not been able to use the DAP (Developmentally Appropriate Practice) approach fully, and has not been able to carry out the philosophy and ways for developing a curriculum based on play. However, quite a lot of research found good practices implemented in learning centers in early childhood education institutions, such as develop children's independence programs through habituation to toilet training and fantasy play.

Résumé :

ABSTRAK Penelitian ini mempunyai tujuan yaitu ingin menganalisis apakah terdapat indikasi window dressing dalam laporan keuangan dilihat dari nilai cash holding, financial leverage dan nilai perusahaan pada sektor energi yang terdaftar di Indeks Saham Syariah Indonesia (ISSI) Bursa Efek Indonesia selama periode 2017-2020. Metode penelitian yang diterapkan yakni uji Beda t-test menggunakan uji Mann Whitney. Sampel yang dipakai ada 22 perusahaan sektor energi di ISSI BEI untuk rentang waktu 2017 triwulan pertama sampai 2020 triwulan keempat. Berdasarkan hasil analisa dalam riset ini membuktikan kalau tidak ada perbedaan nilai cash holding, financial leverage serta nilai perusahaan pada triwulan IV terhadap nilai dalam triwulan I, triwuulan II serta triwulan III. Hal ini mengidentifikasi bahwa perusahaan tidak mengindikasikan gejala window dressing. Sehingga dapat ditarik kesimpulan bahwa beberapa perusahaan di sektor energi yang tertera di ISSI BEI pada tahun 2017 hingga 2020 tidak terindikasi melaksanakan praktik window dressing. Hal ini dapat digunakan sebagai dokumen evaluasi bagi perusahaan di sektor energi untuk lebih meningkatkan operasional mereka. Untuk menghindari adanya indikasi window dressing, perusahaan energi yang terdaftar di ISSI BEI harus memprioritaskan upaya strategis dalam meningkatkan kinerja keuangan perusahaan sehingga cash holding, financial leverage, dan nilai perusahaan dapat mencerminkan situasi perusahaan. Kata kunci: window dressing, cash holding, financial leverage, nilai perusahaan. ABSTRACT This study aimed to analyze whether there are indications of window dressing in financial statements seen from the value of cash holding, financial leverage and company value in the energy sector listed on the Indonesian Sharia Stock Index (ISSI) of the Indonesia Stock Exchange (IDX) during the 2017-2020 period. The research method applied was the Different t-test using the Mann Whitney test. The sample used is 22 energy sector companies on the ISSI IDX for the period of 2017 first quarter to 2020 fourth quarter. Based on the results of the analysis, it proves that there is no difference in the value of cash holding, financial leverage and the value of the company in the 4th quarter of the value in the 1st, 2nd and 3rd quarters. This indicates that the company has no indication of window dressing symptoms. So it can be concluded that several companies in the energy sector listed on the ISSI IDX in 2017 to 2020 are not indicated to carry out window dressing practices. It can be used as an evaluation document for companies in the energy sector to further improve their operations. To avoid any indication of window dressing, energy companies listed on the ISSI IDX must prioritize strategic efforts in improving the company's financial performance so that cash holding, financial leverage, and company value can reflect the company's situation. Keywords: window dressing, cash holding, financial leverage, firm value. REFERENCES Alandari, T. rohmadoni. (2016).

Résumé :

Ionic liquids (ILs) are a unique class of electrolytes, which characteristics make them suitable for use in solar cells, supercapacitors, and fuel cells1. Due to the appealing properties such as good electrochemical stability, low vapour pressure, high concentration of ions and the lack of solvent, they have been under intense study since the early 2000s. Although numerous theoretical2,3, computational4,5, and experimental studies6,7 have shed light on the interfacial properties of ILs, which differ noticeably from the aqueous electrolytes, multiple open questions remain. One such problem is how the interfacial capacitance is affected by the ambient temperature, as studies have shown both positive and negative temperature dependences8,9. Understanding the temperature dependence of interfacial capacitance is crucial as it is relevant for the description of energy storage and is one of the few quantities, which can be estimated both experimentally and computationally. In this study, we combine the density functional theory (DFT) calculations with molecular dynamics (MD) simulations of graphene (Gr) | EMImBF4 IL interface to explain the effect of temperature on capacitance. MD simulations allow us to investigate the probable distribution of ions near the electrode’s surface and relate the changes of ILs structure to the capacitance using the interfacial bilayer model (IBL). We show that the increase of temperature affects the capacitance near the potential of zero charge by attenuating the overscreening without a notable change in the IL interfacial structure. The characteristic peaks and plateaus in the capacitance potential dependence are explained through the concepts of IL layering and saturation of the second IL layer described in the IBL. Using the DFT calculations, we estimate the impact of the quantum capacitance of Gr on the total interfacial capacitance and its temperature dependence. By accounting for the limiting quantum capacitance, the total interfacial capacitance was significantly altered in the case of the Gr electrode, as the effect of the temperature was dampened, and a V-shaped capacitance curve was obtained.

The optical setup for holographic projection on the scatterings in fluorescent liquids is presented. Such media can be used as volumetric screens for near-eye holographic displays, solving the problem of speckle noise and very small exit pupils in existing setups. Three different oils (canola, olive and engine oil) with 532 nm laser and tonic water with 405 nm laser are used for projecting holographic fields, the quality of such images is investigated. The laser wavelength is cut out from acquisition on a camera and only filtered fluorescent light is observed. The best and brightest results are obtained with engine oil. Full Text: PDF ReferencesX.

Résumé :

Dipterological surveys were conducted in different sites in western and central parts of northern Iran (Guilan, Mazandaran, Kordestan, East and West Azerbaijan and Ardabil provinces) during 2010–2011 using Malaise traps, and during 2012–2014 employing sweep nets. A total of 110 species were collected, including 42 Dolichopodinae. Eleven dolichopodine species proved new to science, eight of which are described here: Dolichopus fuscicercus sp. nov., D. subimmaculatus sp. nov., Gymnopternus flavitibia sp. nov., G. atratus sp. nov., Hercostomus setitibia sp. nov., H. albicoxa sp. nov., Poecilobothrus annulitarsis sp. nov. and P. innotabilis sp. nov. Some of these species strongly resemble European species and even share near identical conspicuous male secondary sexual characters.

Résumé :

5550 Background: We previously completed a phase I study of a polyvalent vaccine containing GM2, Globo-H, LeY, Tn-MUC1, Tn(c), STn(c) and TF(c) antigens (AGs) individually conjugated to KLH and mixed with adjuvant OPT-821. We showed safe induction of antibody (ab) responses to 5 of the 7 vaccine AGs. Data has shown that tumor vaccine efficacy may be enhanced through disruption of angiogenesis thus providing a rationale for combining BEV with the polyvalent vaccine. We conducted an IRB-approved pilot study to evaluate the safety and immunogenicity of the poly-KLH-vaccine when given with BEV in OC in remission. Methods: Pts with recurrent OC in ≥2nd complete or partial remission were enrolled from 12/2010-03/2012. Pts received 6 vaccines and BEV over 17 weeks. BEV was continued beyond the vaccination phase. Treatment was continued until disease progression or toxicity. Serologic IgM and IgG responses were measured by ELISA against each AG. Wilcoxon signed rank test was used to test changes in cytokines (CKs): FGFβ, IL-8, PDGF, VEGF measured by angio multiplex assay. Results: n=21 Median age 56yrs (51-70). 2, 8, 8, 3 pts were in 2nd, 3rd, 4th, 5th remission, respectively. 1 DLT (gr 4 fever post vaccine #2). Immune Results: n=19 IgG +/or IgM: ≥3 AGs in 17pts. IgM: ≥1 AG in 19pts, ≥3 AGs in 15pts. IgG: ≥1 AG in 17pts, ≥3 AGs in 3pts. CK Results: In 10 pts who completed 6 vaccines there was a mean (median) decrease in VEGF of 144 (111) pg/ml at the 17-week timepoint compared to baseline (p=0.05). For 8 pts who did not complete all 6 vaccines there was a mean (median) increase of 76 (69) pg/ml compared to baseline at the off-study visit (p=0.16). There was no statistically significant change in the other CKs compared to baseline values. At last follow-up, 18 pts had recurred and 3 pts had died. The median PFS was 5.6mths. Conclusions: 89% of pts responded to ≥3 AGs comparable to the 89% response in our prior phase I trial without BEV. BEV and polyvalent-KLH vaccine can be safely administered together with retention of the vaccine’s immunogenicity. Serum VEGF levels decreased in patients on continued BEV therapy. Clinical trial information: NCT01223235. [Table: see text]
