The crystal structure of the 1+2 mixed-layer Aurivillius phase Bi 5Ti 1.5W 1.5O 15 (SG I2cm n o 46: -cba, Z=4, a=5.4092(3) Å, b=5.3843(3) Å and c=41.529(3) Å) consisting of the ordered intergrowth of one and two octahedra thick perovskite-type blocks separated by [Bi 2O 2] 2+ slabs is reported. Supported by an electron diffraction investigation and, using the Rietveld analysis, it is shown that this compound should be described using a I-centering lattice in agreement with the generalised structural model of the Aurivillius type compounds recently presented by the authors. The structure of this Bi 5Ti 1.5W 1.5O 15 phase is analyzed in comparison with the related simple members (Bi 2WO 6 and Bi 3Ti 1.5W 0.5O 9). The crystal structure of Bi 3Ti 1.5W 0.5O 9 is also reported.

W-18 (4-chloro-N-[1-[2-(4-nitrophenyl)ethyl]-2-piperidinylidene]-benzenesulfonamide) and W-15 (4-chloro-N-[1-(2-phenylethyl)-2-piperidinylidene]-benzenesulfonamide) represent two emerging drugs of abuse chemically related to the potent opioid agonist fentanyl (N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylpropanamide). Here, we describe the comprehensive pharmacological profiles of W-18 and W-15, as examination of their structural features predicted that they might lack opioid activity. We found W-18 and W-15 to be without detectible activity at μ, δ, κ, and nociception opioid receptors in a variety of assays. We also tested W-18 and W-15 for activity as allosteric modulators at opioid receptors and found them devoid of significant positive or negative allosteric modulatory activity. Comprehensive profiling at essentially all the druggable GPCRs in the human genome using the PRESTO-Tango platform revealed no significant activity. Weak activity at the sigma receptors and the peripheral benzodiazepine receptor was found for W-18 (Ki = 271 nM). W-18 showed no activity in either the radiant heat tail-flick or the writhing assays and also did not induce classical opioid behaviors. W-18 is extensively metabolized, but its metabolites also lack opioid activity. Thus, although W-18 and W-15 have been suggested to be potent opioid agonists, our results reveal no significant activity at these or other known targets for psychoactive drugs.

Successfully aging elderly (SAE: A short overview of some important aspects of successful aging

Full Text Available Whether one falls into the category of successfully aging elderly (SAE is generally determined by biological, medical, psychological, and cognitive factors. SAE, pathological aging and usual aging, are the three subgroups presented in the seminal science paper by Rowe & Kahn in 1987. SAE is currently vaguely defined as being free of disease, having preserved cognitive function and an active life, but a more detailed definition is lacking. As a result, the research on SAE is heterogeneous and hard to summarize. Nevertheless, it is clear that genetics, health, basic aging mechanisms, brain changes, cognition early in life, education level, lifestyle factors, subjective factors, the availability of societal health care, environmental factors, and any interaction between all these variables, are important. There are also methodological difficulties associated with studies of causal relationships across the lifespan. Obtaining a detailed understanding of SAE research will be a challenging task for future researchers

A novel cable-type flexible supercapacitor with excellent performance is fabricated using 3D polypyrrole(PPy)-MnO2 -CNT-cotton thread multi-grade nanostructure-based electrodes. The multiple supercapacitors with a high areal capacitance 1.49 F cm(-2) at a scan rate of 1 mV s(-1) connected in series and in parallel can successfully drive a LED segment display. Such an excellent performance is attributed to the cumulative effect of conducting single-walled carbon nanotubes on cotton thread, active mesoporous flower-like MnO2 nanoplates, and PPy conductive wrapping layer improving the conductivity, and acting as pseudocapacitance material simultaneously.

Sentongo, Samuel; Carter, Austin; Cecil, Christopher; Feier, Ioan

2017-11-01

This paper identifies and evaluates the design characteristics of a novel airfoil that harnesses the Magnus Effect, applying a moving-surface boundary-layer control (MSBC) method to a Formula SAE Vehicle. The MSBC minimizes adverse pressure gradient and delays boundary layer separation through the use of a conveyor belt that interacts with the airfoil boundary layer. The MSBC allows dynamic control of the aerodynamic coefficients by variation of the belt speed, minimizing drag in high speed straights and maximizing downforce during vehicle cornering. A conveyer belt wing measuring approximately 0.9 x 0.9m in planform was designed and built to test the mechanical setup for such a MSBC wing. This study follows the relationship between inputted power and outputted surface velocity, with the goal being to maximize speed output vs. power input. The greatest hindrance to maximizing speed output is friction among belts, rollers, and stationary members. The maximum belt speed achieved during testing was 5.9 m/s with a power input of 48.8 W, which corresponds to 45.8 N of downforce based on 2D CFD results. Ongoing progress on this project is presented. United States Air Force Academy.

Small ubiquitin-like modifier (SUMO) family proteins regulate target-protein functions by post-translational modification. However, a potent and selective inhibitor targeting the SUMO pathway has been lacking. Here we describe ML-792, a mechanism-based SUMO-activating enzyme (SAE) inhibitor with nanomolar potency in cellular assays. ML-792 selectively blocks SAE enzyme activity and total SUMOylation, thus decreasing cancer cell proliferation. Moreover, we found that induction of the MYC oncogene increased the ML-792-mediated viability effect in cancer cells, thus indicating a potential application of SAE inhibitors in treating MYC-amplified tumors. Using ML-792, we further explored the critical roles of SUMOylation in mitotic progression and chromosome segregation. Furthermore, expression of an SAE catalytic-subunit (UBA2) S95N M97T mutant rescued SUMOylation loss and the mitotic defect induced by ML-792, thus confirming the selectivity of ML-792. As a potent and selective SAE inhibitor, ML-792 provides rapid loss of endogenously SUMOylated proteins, thereby facilitating novel insights into SUMO biology.

Marincola, Gabriella; Wolz, Christiane

In gram-positive bacteria, RNase J1, RNase J2 and RNase Y are thought to be major contributors to mRNA degradation and maturation. In Staphylococcus aureus, RNase Y activity is restricted to regulating the mRNA decay of only certain transcripts. Here the saePQRS operon was used as a model to analyze RNase Y specificity in living cells. A RNase Y cleavage site is located in an intergenic region between saeP and saeQ. This cleavage resulted in rapid degradation of the upstream fragment and stabilization of the downstream fragment. Thereby, the expression ratio of the different components of the operon was shifted towards saeRS, emphasizing the regulatory role of RNase Y activity. To assess cleavage specificity different regions surrounding the sae CS were cloned upstream of truncated gfp, and processing was analyzed in vivo using probes up- and downstream of CS. RNase Y cleavage was not determined by the cleavage site sequence. Instead a 24-bp double-stranded recognition structure was identified that was required to initiate cleavage 6 nt upstream. The results indicate that RNase Y activity is determined by secondary structure recognition determinants, which guide cleavage from a distance. © The Author(s) 2017.

SaeRS Is Responsive to Cellular Respiratory Status and Regulates Fermentative Biofilm Formation in Staphylococcus aureus.

Biofilms are multicellular communities of microorganisms living as a quorum rather than as individual cells. The bacterial human pathogen Staphylococcus aureus uses oxygen as a terminal electron acceptor during respiration. Infected human tissues are hypoxic or anoxic. We recently reported that impaired respiration elicits a p rogrammed c ell l ysis (PCL) phenomenon in S. aureus leading to the release of cellular polymers that are utilized to form biofilms. PCL is dependent upon the AtlA murein hydrolase and is regulated, in part, by the SrrAB two-component regulatory system (TCRS). In the current study, we report that the SaeRS TCRS also governs fermentative biofilm formation by positively influencing AtlA activity. The SaeRS-modulated factor fibronectin-binding protein A (FnBPA) also contributed to the fermentative biofilm formation phenotype. SaeRS-dependent biofilm formation occurred in response to changes in cellular respiratory status. Genetic evidence presented suggests that a high cellular titer of phosphorylated SaeR is required for biofilm formation. Epistasis analyses found that SaeRS and SrrAB influence biofilm formation independently of one another. Analyses using a mouse model of orthopedic implant-associated biofilm formation found that both SaeRS and SrrAB govern host colonization. Of these two TCRSs, SrrAB was the dominant system driving biofilm formation in vivo We propose a model wherein impaired cellular respiration stimulates SaeRS via an as yet undefined signal molecule(s), resulting in increasing expression of AtlA and FnBPA and biofilm formation.

2009-01-01

Corrosion of SAE 1045 steel/WC-Co/Ni-Cu-Ni/SAE 1045 steel interfaces was investigated in 0.6 M NaCl solution using an electrochemical microcell, which enables local electrochemical characterization at the micrometer scale. Two pieces of steel, one with a WC-Co coating covered with Ni (12 μm) and Cu (5 μm) layers, and the other with a Ni (15 μm) layer, were welded by dynamic diffusion bonding. A WC-Co coating was applied to the steel by the high velocity oxygen-fuel process, and Ni-Cu and Ni layers by electroplating. Polarization curves were recorded using an electrochemical microcell. Different regions of welded samples were investigated, including steel, cermet coating, and steel/cermet and steel/Ni-Cu-Ni/cermet interfaces. Optical and electronic microscopes were employed to study the corroded regions. Potentiodynamic polarization curves obtained using the microcell revealed that the base metal was more susceptible to corrosion than the cermet. In addition, cermet steel/cermet and steel/Ni-Cu-Ni/cermet joints exhibited different breakdown potentials. Steel was strongly corroded in the regions adjacent to the interfaces, while the cermet was less corroded. Iron oxides/hydroxides and chloride salts were the main corrosion products of steel. After removal of the superficial layer of corrosion products, iron oxides were mainly observed. Chloride ions were detected mainly on a copper-enriched layer placed between two Ni-enriched layers.

Mre11-Sae2 and RPA Collaborate to Prevent Palindromic Gene Amplification.

2015-11-05

Foldback priming at DNA double-stranded breaks is one mechanism proposed to initiate palindromic gene amplification, a common feature of cancer cells. Here, we show that small (5-9 bp) inverted repeats drive the formation of large palindromic duplications, the major class of chromosomal rearrangements recovered from yeast cells lacking Sae2 or the Mre11 nuclease. RPA dysfunction increased the frequency of palindromic duplications in Sae2 or Mre11 nuclease-deficient cells by ∼ 1,000-fold, consistent with intra-strand annealing to create a hairpin-capped chromosome that is subsequently replicated to form a dicentric isochromosome. The palindromic duplications were frequently associated with duplication of a second chromosome region bounded by a repeated sequence and a telomere, suggesting the dicentric chromosome breaks and repairs by recombination between dispersed repeats to acquire a telomere. We propose secondary structures within single-stranded DNA are potent instigators of genome instability, and RPA and Mre11-Sae2 play important roles in preventing their formation and propagation, respectively.

Vehicle to grid communication standards enable interoperability among vehicles, charging stations and utility providers and provide the capability to implement charge management. Several standards initiatives by the Society of Automobile Engineers (SAE), International Standards Organization and International Electrotechnical Commission (ISO/IEC), and ZigBee/HomePlug Alliance are developing requirements for communication messages and protocols. Recent work by the Electric Power Research Institute (EPRI) in collaboration with SAE and automobile manufacturers has identified vehicle to grid communication performance requirements and developed a test plan as part of SAE J2931/1 committee work. This laboratory test plan was approved by the SAE J2931/1 committee and included test configurations, test methods, and performance requirements to verify reliability, robustness, repeatability, maximum communication distance, and authentication features of power line carrier (PLC) communication modules at the internet protocol layer level. The goal of the testing effort was to select a communication technology that would enable automobile manufacturers to begin the development and implementation process. The EPRI/Argonne National Laboratory (ANL)/Pacific Northwest National Laboratory (PNNL) testing teams divided the testing so that results for each test could be presented by two teams, performing the tests independently. The PNNL team performed narrowband PLC testing including the Texas Instruments (TI) Concerto, Ariane Controls AC-CPM1, and the MAXIM Tahoe 2 evaluation boards. The scope of testing was limited to measuring the vendor systems communication performance between Electric Vehicle Support Equipment (EVSE) and plug-in electric vehicles (PEV). The testing scope did not address PEV’s CAN bus to PLC or PLC to EVSE (Wi-Fi, cellular, PLC Mains, etc.) communication integration. In particular, no evaluation was performed to delineate the effort needed to translate the IPv6

Eap and Emp are two Staphylococcus aureus adhesins initially described as extracellular matrix binding proteins. Eap has since emerged as being important in adherence to and invasion of eukaryotic cells, as well as being described as an immunomodulator and virulence factor in chronic infections. This paper describes the mapping of the transcription start point of the eap and emp promoters. Moreover, using reporter-gene assays and real-time PCR in defined regulatory mutants, environmental conditions and global regulators affecting expression of eap and emp were investigated. Marked differences were found in expression of eap and emp between strain Newman and the 8325 derivatives SH1000 and 8325-4. Moreover, both genes were repressed in the presence of glucose. Analysis of expression of both genes in various regulatory mutants revealed that sarA and agr were involved in their regulation, but the data suggested that there were additional regulators of both genes. In a sae mutant, expression of both genes was severely repressed. sae expression was also reduced in the presence of glucose, suggesting that repression of eap and emp in glucose-containing medium may, in part, be a consequence of a decrease in expression of sae.

A model for fracture toughness evaluation of the carburized layer for SAE 5115 steel

The purpose of this work is to propose a model for evaluating the fracture toughness along the SAE 5115 steel carburized layer. Due to the small thickness of those layers, it is impossible to machine specimens from those layer in accordance with standards. For simulating the microstructures of the carburized layer in order to get samples for tensile and the fracture toughness testing, specimens of SAE 5115, 5140, 5160, and 52100 steels have been machined, assuming the local influence just the...

The SaeR/S gene regulatory system induces a pro-inflammatory cytokine response during Staphylococcus aureus infection.

Directory of Open Access Journals (Sweden)

Robert L Watkins

Full Text Available Community-associated methicillin-resistant Staphylococcus aureus accounts for a large portion of the increased staphylococcal disease incidence and can cause illness ranging from mild skin infections to rapidly fatal sepsis syndromes. Currently, we have limited understanding of S. aureus-derived mechanisms contributing to bacterial pathogenesis and host inflammation during staphylococcal disease. Herein, we characterize an influential role for the saeR/S two-component gene regulatory system in mediating cytokine induction using mouse models of S. aureus pathogenesis. Invasive S. aureus infection induced the production of localized and systemic pro-inflammatory cytokines, including tumor necrosis factor alpha (TNF-α, interferon gamma (IFN-γ, interleukin (IL-6 and IL-2. In contrast, mice infected with an isogenic saeR/S deletion mutant demonstrated significantly reduced pro-inflammatory cytokine levels. Additionally, secreted factors influenced by saeR/S elicited pro-inflammatory cytokines in human blood ex vivo. Our study further demonstrated robust saeR/S-mediated IFN-γ production during both invasive and subcutaneous skin infections. Results also indicated a critical role for saeR/S in promoting bacterial survival and enhancing host mortality during S. aureus peritonitis. Taken together, this study provides insight into specific mechanisms used by S. aureus during staphylococcal disease and characterizes a relationship between a bacterial global regulator of virulence and the production of pro-inflammatory mediators.

Effect of particle size on the friction welding of Al2O3 reinforced 6160 Al alloy composite and SAE 1020 steel

International Nuclear Information System (INIS)

Hascalik, Ahmet; Orhan, Nuri

2007-01-01

The aim of this study is to investigate the feasibility of joining Al 2 O 3 reinforced Al alloy composite to SAE 1020 steel by rotational friction welding. The aluminum-based metal matrix composite (MMC) material containing 5, 10 and 15 vol% Al 2 O 3 particles with average particle sizes of 30 and 60 μm was produced by powder metallurgy technique. The integrity of the joints has been investigated by optical and scanning electron microscopy, while the mechanical properties assessment included microhardness and shear tests. Results indicated that Al/Al 2 O 3 composite could be joined to SAE 1020 steel by friction welding. However, it was pointed out that the quality of the joint was effected negatively with the increase in particle size and volume percentage of the oxide particles in the MMC

Tritium stripping in a nitrogen glovebox using SAES St 198

International Nuclear Information System (INIS)

Klein, J.E.; Wermer, J.R.

1994-01-01

SAES metal getter material St 198 was chosen for glovebox stripper tests to evaluate its effectiveness of removing tritium from a nitrogen atmosphere. The St 198 material is unique from a number of other metal hydride-based getter materials in that it is relatively inert to nitrogen and can thus be used in nitrogen glovebox atmospheres. Six tritium stripper experiments which mock-up the use of a SAES St 198 stripper bed for a full-scale (10,500 liter) nitrogen glovebox have been completed. Experiments consisted of a release of small quantity of protium/deuterium spiked with tritium which were scaled to simulate tritium releases of 0.1 g., 1.0 g., and 10 g. into the glovebox. The tritium spike allows detection using tritium ion chambers. The St 198 stripper system produced a reduction in tritium activity of approximately two orders of magnitude in 24 hours (6--8 atmosphere turn-overs) of stripper operation

This paper showed the comparative of direct estimation and indirect/Small Area Estimation (SAE) model. Model selection included resolve multicollinearity problem in auxiliary variable, such as choosing only variable non-multicollinearity and implemented principal component (PC). Concern parameters in this paper were the proportion of agricultural venture poor households and agricultural poor households area level in West Java Province. The approach for estimating these parameters could be performed based on direct estimation and SAE. The problem of direct estimation, three area even zero and could not be conducted by directly estimation, because small sample size. The proportion of agricultural venture poor households showed 19.22% and agricultural poor households showed 46.79%. The best model from agricultural venture poor households by choosing only variable non-multicollinearity and the best model from agricultural poor households by implemented PC. The best estimator showed SAE better then direct estimation both of the proportion of agricultural venture poor households and agricultural poor households area level in West Java Province. The solution overcame small sample size and obtained estimation for small area was implemented small area estimation method for evidence higher accuracy and better precision improved direct estimator.

Giant Spin Hall Effect and Switching Induced by Spin-Transfer Torque in a W /Co40Fe40B20/MgO Structure with Perpendicular Magnetic Anisotropy

Science.gov (United States)

Hao, Qiang; Xiao, Gang

2015-03-01

We obtain robust perpendicular magnetic anisotropy in a β -W /Co40Fe40B20/MgO structure without the need of any insertion layer between W and Co40Fe40B20 . This is achieved within a broad range of W thicknesses (3.0-9.0 nm), using a simple fabrication technique. We determine the spin Hall angle (0.40) and spin-diffusion length for the bulk β form of tungsten with a large spin-orbit coupling. As a result of the giant spin Hall effect in β -W and careful magnetic annealing, we significantly reduce the critical current density for the spin-transfer-torque-induced magnetic switching in Co40Fe40B20 . The elemental β -W is a superior candidate for magnetic memory and spin-logic applications.

Fusion and quasifission studies for the 40Ca+186W,192Os reactions

2017-09-01

Background: All elements above atomic number 113 have been synthesized using hot fusion reactions with calcium beams on statically deformed actinide target nuclei. Quasifission and fusion-fission are the two major mechanisms responsible for the very low production cross sections of superheavy elements. Purpose: To achieve a quantitative measurement of capture and quasifission characteristics as a function of beam energy in reactions forming heavy compound systems using calcium beams as projectiles. Methods: Fission fragment mass-angle distributions were measured for the two reactions 40Ca+186W and 40C+192Os, populating 226Pu and 232Cm compound nuclei, respectively, using the Heavy Ion Accelerator Facility and CUBE spectrometer at the Australian National University. Mass ratio distributions, angular distributions, and total fission cross sections were obtained from the experimental data. Simulations to match the features of the experimental mass-angle distributions were performed using a classical phenomenological approach. Results: Both 40Ca+186W and 40C+192Os reactions show strong mass-angle correlations at all energies measured. A maximum fusion probability of 60 -70 % is estimated for the two reactions in the energy range of the present study. Coupled-channels calculations assuming standard Woods-Saxon potential parameters overpredict the capture cross sections. Large nuclear potential diffuseness parameters ˜1.5 fm are required to fit the total capture cross sections. The presence of a weak mass-asymmetric quasifission component attributed to the higher angular momentum events can be reproduced with a shorter average sticking time but longer mass-equilibration time constant. Conclusions: The deduced above-barrier capture cross sections suggest that the dissipative processes are already occurring outside the capture barrier. The mass-angle correlations indicate that a compact shape is not achieved for deformation aligned collisions with lower capture barriers

SAE for the prediction of road traffic status from taxicab operating data and bus smart card data

Science.gov (United States)

Zhengfeng, Huang; Pengjun, Zheng; Wenjun, Xu; Gang, Ren

Road traffic status is significant for trip decision and traffic management, and thus should be predicted accurately. A contribution is that we consider multi-modal data for traffic status prediction than only using single source data. With the substantial data from Ningbo Passenger Transport Management Sector (NPTMS), we wished to determine whether it was possible to develop Stacked Autoencoders (SAEs) for accurately predicting road traffic status from taxicab operating data and bus smart card data. We show that SAE performed better than linear regression model and Back Propagation (BP) neural network for determining the relationship between road traffic status and those factors. In a 26-month data experiment using SAE, we show that it is possible to develop highly accurate predictions (91% test accuracy) of road traffic status from daily taxicab operating data and bus smart card data.

Retained Austenite in SAE 52100 Steel Post Magnetic Processing and Heat Treatment

Energy Technology Data Exchange (ETDEWEB)

Pappas, Nathaniel R [ORNL; Watkins, Thomas R [ORNL; Cavin, Odis Burl [ORNL; Jaramillo, Roger A [ORNL; Ludtka, Gerard Michael [ORNL

2007-01-01

Steel is an iron-carbon alloy that contains up to 2% carbon by weight. Understanding which phases of iron and carbon form as a function of temperature and percent carbon is important in order to process/manufacture steel with desired properties. Austenite is the face center cubic (fcc) phase of iron that exists between 912 and 1394 C. When hot steel is rapidly quenched in a medium (typically oil or water), austenite transforms into martensite. The goal of the study is to determine the effect of applying a magnetic field on the amount of retained austenite present at room temperature after quenching. Samples of SAE 52100 steel were heat treated then subjected to a magnetic field of varying strength and time, while samples of SAE 1045 steel were heat treated then subjected to a magnetic field of varying strength for a fixed time while being tempered. X-ray diffraction was used to collect quantitative data corresponding to the amount of each phase present post processing. The percentage of retained austenite was then calculated using the American Society of Testing and Materials standard for determining the amount of retained austenite for randomly oriented samples and was plotted as a function of magnetic field intensity, magnetic field apply time, and magnetic field wait time after quenching to determine what relationships exist with the amount of retained austenite present. In the SAE 52100 steel samples, stronger field strengths resulted in lower percentages of retained austenite for fixed apply times. The results were inconclusive when applying a fixed magnetic field strength for varying amounts of time. When applying a magnetic field after waiting a specific amount of time after quenching, the analyses indicate that shorter wait times result in less retained austenite. The SAE 1045 results were inconclusive. The samples showed no retained austenite regardless of magnetic field strength, indicating that tempering removed the retained austenite. It is apparent

Tritium stripping in a nitrogen glove box using palladium/zeolite and SAES St 198 trademark

International Nuclear Information System (INIS)

Klien, J.E.; Wermer, J.R.

1995-01-01

Glove box clean-up experiments were conducted in a nitrogen glove box using palladium deposited on zeolite (Pd/z) and a SAES St 198 trademark getter as tritium stripping materials. Protium/deuterium samples spiked with tritium were released into a 620 liter glove box to simulate tritium releases in a 10,500 liter glove box. The Pd/z and the SAES St 198 trademark stripper beds produced a reduction in tritium activity of approximately two to three orders of magnitude and glove box clean-up was limited by a persistent background tritium activity level. Attempts to significantly reduce the glove box activity to lower levels without purging were unsuccessful

We demonstrated a high-power continuous-wave (CW) polycrystalline Yb:YAG ceramic laser pumped by fiber-pigtailed laser diode at 968 nm with 400 mum fiber core. The Yb:YAG ceramic laser performance was compared for different Yb(3+) ion concentrations in the ceramics by using a conventional end-pump laser cavity consisting of two flat mirrors with output couplers of different transmissions. A CW laser output of 40 W average power with M(2) factor of 5.8 was obtained with 5 mol% Yb concentration under 120 W incident pump power. This is to the best of our knowledge the highest output power in end-pumped bulk Yb:YAG ceramic laser.

1994-01-01

High-spin states of the stable isotope 182 W have been studied using the reactions 176 Yb( 13 C,α3n) 182 W and 176 Yb( 9 Be,3n) 182 W at beam energies of 65 and 40 MeV, respectively. Three, possibly four, new intrinsic states at high spins have been observed corresponding to different high-K four-quasi-particle structures. The K π =15 + and 17 - levels have lifetimes of 78(15) and 25(10) ns, respectively. Rotational bands are observed built on the K π =16 + and 17 - yrast states. The coupling of Nilsson orbitals which give rise to high-K states at the yrast line and the K-forbiddenness of the K π =15 + isomeric decay are discussed. (orig.)

2007-02-01

Cartilaginous fish, primarily sharks, rays and skates (elasmobranchs), appeared 450 million years ago. They are the most primitive vertebrates, exhibiting jaws and teeth, adaptive immunity, a pressurized circulatory system, thymus, spleen, and a liver comparable to that of humans. The most used elasmobranch in biomedical research is the spiny dogfish shark, Squalus acanthias. Comparative genomic analysis of the dogfish shark, the little skate (Leucoraja erincea), and other elasmobranchs have yielded insights into conserved functional domains of genes associated with human liver function, multidrug resistance, cystic fibrosis, and other biomedically relevant processes. While genomic information from these animals is informative in an evolutionary framework, experimental verification of functions of genomic sequences depends heavily on cell culture approaches. We have derived the first multipassage, continuously proliferating cell line of a cartilaginous fish. The line was initiated from embryos of the spiny dogfish shark. The cells were maintained in a medium modified for fish species and supplemented with cell type-specific hormones, other proteins and sera, and plated on a collagen substrate. SAE cells have been cultured continuously for three years. These cells can be transfected by plasmids and have been cryopreserved. Expressed Sequence Tags generated from a normalized SAE cDNA library included a number of markers for cartilage and muscle, as well as proteins influencing tissue differentiation and development, suggesting that SAE cells may be of mesenchymal stem cell origin. Examination of SAE EST sequences also revealed a cartilaginous fish-specific repetitive sequence that may be evidence of an ancient mobile genetic element that most likely was introduced into the cartilaginous fish lineage after divergence from the lineage leading to teleosts.

SAE2.py: a python script to automate parameter studies using SCREAMER with application to magnetic switching on Z

International Nuclear Information System (INIS)

Orndorff-Plunkett, Franklin

2011-01-01

The SCREAMER simulation code is widely used at Sandia National Laboratories for designing and simulating pulsed power accelerator experiments on super power accelerators. A preliminary parameter study of Z with a magnetic switching retrofit illustrates the utility of the automating script for optimizing pulsed power designs. SCREAMER is a circuit based code commonly used in pulsed-power design and requires numerous iterations to find optimal configurations. System optimization using simulations like SCREAMER is by nature inefficient and incomplete when done manually. This is especially the case when the system has many interactive elements whose emergent effects may be unforeseeable and complicated. For increased completeness, efficiency and robustness, investigators should probe a suitably confined parameter space using deterministic, genetic, cultural, ant-colony algorithms or other computational intelligence methods. I have developed SAE2 - a user-friendly, deterministic script that automates the search for optima of pulsed-power designs with SCREAMER. This manual demonstrates how to make input decks for SAE2 and optimize any pulsed-power design that can be modeled using SCREAMER. Application of SAE2 to magnetic switching on model of a potential Z refurbishment illustrates the power of SAE2. With respect to the manual optimization, the automated optimization resulted in 5% greater peak current (10% greater energy) and a 25% increase in safety factor for the most highly stressed element.

We report the results of the {sup 12}CO (J = 3−2) and HCO{sup +} (J = 4−3) observations of the W40 H ii region with the Atacama Submillimeter Telescope Experiment (ASTE) 10 m telescope (HPBW ≃ 22″) to search for molecular outflows and dense clumps. We found that the velocity field in the region is highly complex, consisting of at least four distinct velocity components at V{sub LSR} ≃ 3, 5, 7, and 10 km s{sup −1}. The ∼7 km s{sup −1} component represents the systemic velocity of cold gas surrounding the entire region, and causes heavy absorption in the {sup 12}CO spectra over the velocity range 6 ≲ V{sub LSR} ≲ 9 km s{sup −1}. The ∼5 and ∼10 km s{sup −1} components exhibit high {sup 12}CO temperature (≳40 K) and are found mostly around the H ii region, suggesting that these components are likely to be tracing dense gas interacting with the expanding shell around the H ii region. Based on the {sup 12}CO data, we identified 13 regions of high velocity gas, which we interpret as candidate outflow lobes. Using the HCO{sup +} data, we also identified six clumps and estimated their physical parameters. On the basis of the ASTE data and near-infrared images from 2MASS, we present an updated three-dimensional model of this region. In order to investigate molecular outflows in W40, the SiO (J = 1−0, v = 0) emission line and some other emission lines at 40 GHz were also observed with the 45 m telescope at the Nobeyama Radio Observatory, but they were not detected at the present sensitivity.

Black-Right-Pointing-Pointer Thermomechanical processing modifies size + morphology of bainitic ferrite. Black-Right-Pointing-Pointer Processing involves hot deformation prior to/during/after austenitizing. Black-Right-Pointing-Pointer Significant improvement in mechanical strength achieved. Black-Right-Pointing-Pointer Similar study on high carbon, low alloy steel not reported in the literature. - Abstract: The present study attempts to tailor the size, morphology and distribution of the ferrite needles/sheaves by thermomechanical processing and develop an ultrafine ferrite + martensite duplex microstructure for enhancement of strength and toughness in SAE 52100 steel. The thermo-mechanical routine included 5% hot deformation before, during or after austenitizing at 950 Degree-Sign C for 15 min followed by austempering at 270 Degree-Sign C for 30 min and subsequent water quenching to room temperature. Optical/electron microscopy along with X-ray diffraction was used to quantitatively monitor the size, morphology and distribution of the phase or phase aggregate. Significant improvement in nanohardness, wear resistance and elastic modulus and was observed in samples subjected to thermomechanical processing, as compared to that following the same austenitizing and austempering routine without hot deformation at any stage. However, improvement in the bulk mechanical property due to the present thermo-mechanical is lower than that obtained in our earlier study comprising cold deformation prior to austenitizing and austempering.

The value of T1-weighted images in the differentiation between MS, white matter lesions, and subcortical arteriosclerotic encephalopathy (SAE)

Energy Technology Data Exchange (ETDEWEB)

Uhlenbrock, D.; Sehlen, S.

1989-07-01

The aim of the study was to define reliable criteria for the differentiation of MR imaging between patients with MS and with 'vascular' white matter lesions/SAE. We examined 35 patients with proven MS according to the Poser criteria and 35 patients with other white matter lesions and/or SAE. The result is that with MR a differentiation can be achieved provided that T1-weighted spin-echo sequences are included and the different pattern of distribution is considered. MS plaques are predominantly located in the subependymal region, vascular white matter lesions are mainly located in the water-shed of the superficial middle cerebral branches and the deep perforating long medullary vessels in the centrum semiovale. Infratentorial lesions are more often seen in MS. Confluence at the lateral ventricles is frequently accompanied by confluent abnormalities around the third ventricle, Sylvian aqueduct, and fourth ventricle, which is uncommon in SAE. In MS many lesions visible on T2-weighted images have a cellular or intracellular composition that renders them visible also on T1-weighted ones as regions with low signal intensity and more or less distinct boundary. 'Vascular' white matter lesions and SAE mainly represent demyelination and can therefore be seen on T2-weighted images, but corresponding low signal intensity lesions on T1-weighted images are uncommon. In some exceptions there are such lesions with low signal representing lacunar infarcts or widened Virchow-Robin-spaces. (orig.).

Enhancement of surface properties of SAE 1020 by chromium plasma immersion recoil implantation

International Nuclear Information System (INIS)

Ueda, M.; Mello, C.B.; Beloto, A.F.; Rossi, J.O.; Reuther, H.

2007-01-01

SAE 1020 steel is commonly used as concrete reinforcement and small machine parts, but despite its good mechanical properties, as ductility, hardness and wear resistance, it is susceptible to severe corrosion. It is well known that chromium content above 12% in Fe alloys increases their corrosion resistance. In order to obtain this improvement, we studied the introduction of chromium atoms into the matrix of SAE 1020 steel by recoil implantation process using a plasma immersion ion implantation (PIII) system. Potentiodynamic scans showed that the presence of Cr film leads to a gain in the corrosion potential, from -650 mV to -400 mV. After PIII treatment, the corrosion potential increased further to -340 mV, but the corrosion current density presented no significant change. Vickers microhardness tests showed surface hardness increase of up to about 27% for the treated samples. Auger electron spectroscopy showed that, for a 30 nm film, Cr was introduced for about 20 nm into the steel matrix. Tribology tests, of pin-on-disk type, showed that friction coefficient of treated samples was reduced by about 50% and a change in wear mechanism, from adhesive to abrasive mode, occurred

Room temperature fatigue behaviour of a normalized steel SAE 4140 in torsion

International Nuclear Information System (INIS)

Klumpp, S.; Eifler, D.; Macherauch, E.

1990-01-01

Cyclic deformation behaviour of a normalized steel SAE 4140 in shear strain-controlled torsion is characterized by cyclic softening and cyclic hardening. If mean shear stresses are superimposed to an alternating shear stress, cycle-dependent creep occurs, and the number of cycles to failure decreases. In shear strain-controlled torsional loading, mean stresses are observed to relax nearly to zero within a few cycles. Fatigue life is not influenced by mean shear strains. (orig.) [de

5.6μm quantum cascade lasers based on Al0.78In0.22As/In0.69Ga0.31As active region composition with measured pulsed room temperature wall plug efficiency of 28.3% are reported. Injection efficiency for the upper laser level of 75% was measured by testing devices with variable cavity length. Threshold current density of 1.7kA/cm2 and slope efficiency of 4.9W/A were measured for uncoated 3.15mm x 9µm lasers. Threshold current density and slope efficiency dependence on temperature in the range from 288K to 348K can be described by characteristic temperatures T0 140K and T1 710K, respectively. Pulsed slope efficiency, threshold current density, and wallplug efficiency for a 2.1mm x 10.4µm 15-stage device with the same design and a high reflection-coated back facet were measured to be 1.45W/A, 3.1kA/cm2 , and 18%, respectively. Continuous wave values for the same parameters were measured to be 1.42W/A, 3.7kA/cm2 , and 12%. Continuous wave optical power levels exceeding 0.5W per millimeter of cavity length was demonstrated. When combined with the 40-stage device data, the inverse slope efficiency dependence on cavity length for 15-stage data allowed for separate evaluation of the losses originating from the active region and from the cladding layers of the laser structure. Specifically, the active region losses for the studied design were found to be 0.77cm-1, while cladding region losses - 0.33cm-1. The data demonstrate that active region losses in mid wave infrared quantum cascade lasers largely define total waveguide losses and that their reduction should be one of the main priorities in the quantum cascade laser design.

SAES St 909 pilot scale methane cracking tests

International Nuclear Information System (INIS)

Klein, J. E.; Sessions, H. T.

2008-01-01

Pilot scale (0.5 kg) SAES St 909 methane cracking tests were conducted for potential tritium process applications. Up to 1400 hours tests were done at 700 deg.C, 202.7 kPa (1520 torr) with a 0.03 sLPM feed of methane plus impurities, in a 20 vol% hydrogen, balance helium, stream. Carbon dioxide gettered by St 909 can be equated to an equivalent amount of methane gettered, but equating nitrogen to an equivalent amount of methane was nitrogen feed composition dependent. A decreased hydrogen feed increased methane getter rates while a 30 deg.C drop in one furnace zone increased methane emissions by over a factor of 30. The impact of gettered nitrogen can be somewhat minimized if nitrogen feed to the bed has been stopped and sufficient time given to recover the methane cracking rate. (authors)

Fu, Xiaobin; Wang, Baoyu; Tang, Xuefeng

2017-10-01

With the development of net-shape forming technology, hot forming process is widely applied to manufacturing gear parts, during which, materials suffer severe plastic distortion and microstructure changes continually. In this paper, to understand and model the flow behavior and microstructure evolution, SAE 8620H, a widely used gear steel, is selected as the object and the flow behavior and microstructure evolution are observed by an isothermal hot compression tests at 1273-1373 K with a strain rate of 0.1-10 s-1. Depending on the results of the compression test, a set of internal-state-variable based unified constitutive equations is put forward to describe the flow behavior and microstructure evaluation of SAE 8620H. Moreover, the evaluation of the dislocation density and the fraction of dynamic recrystallization based on the theory of thermal activation is modeled and reincorporated into the constitutive law. The material parameters in the constitutive model are calculated based on the measured flow stress and dynamic recrystallization fraction. The predicted flow stress under different deformation conditions has a good agreement with the measured results.

Full Text Available This paper describes the use of Al2O3/ZrO2 mixed oxides synthesized by sol-gel process with different amounts of ZrO2 (5%, 10%, 15% and 20% by mass in the Al2O3 matrix and different temperatures of calcination, such as interesting inhibitor materials of corrosive processes of SAE 1020 steel. The materials were characterized by Infrared Spectroscopy Fourier Transform (FTIR and X-Ray Diffraction (XRD techniques. FTIR spectra show the typical Al-O and Zr-O bonds vibrations in the mixed oxides. The XRD patterns of the samples calcined at 800 °C and 1000 °C shows the ZrO2 tetragonal and γ-Al2O3 face-centered cubic (FCC phases. The corrosion tests showed that the SAE 1020 steel covered with mixed oxides have an anodic passive region, thereby inhibiting the corrosive processes on the metal surface. Furthermore, the found values for steel coated with mixed oxide synthesized indicate a decrease in corrosion potentials (Ecor and corrosion current (icor. With respect to different samples of mixed oxides, the sample with 20 % of ZrO2 in the Al2O3 matrix proved to be the best inhibitor of steel corrosion, with the lowest values of corrosion potential and corrosion current, - 1.32 V and 0.31 μA cm-2, respectively.

We have generated continuous-wave single-frequency 1.5 W 378 nm radiation by frequency doubling a high-power Ti:sapphire laser in an external enhancement cavity. An LBO crystal that is Brewster-cut and antireflection coated on both ends is used for a long-term stable frequency doubling. By optimizing the input coupler's reflectivity, we could generate 1.5 W 378 nm radiation from a 5 W 756 nm Ti:sapphire laser. According to our knowledge, this is the highest CW frequency-doubled power of a Ti:sapphire laser.

We present a discontinuous harvesting approach for switch capacitor DC-DC converters that enables ultra-low power energy harvesting. By slowly accumulating charge on an input capacitor and then transferring it to a battery in burst-mode, switching and leakage losses in the DC-DC converter can be optimally traded-off with the loss due to non-ideal MPPT operation. The harvester uses a 15pW mode controller, an automatic conversion ratio modulator, and a moving sum charge pump for low startup energy upon a mode switch. In 180nm CMOS, the harvester achieves >40% end-to-end efficiency from 113pW to 1.5μW with 66pW minimum input power, marking a >10× improvement over prior ultra-low power harvesters.

Laser alloying or cladding differs little in principle from the traditional forms of weld overlays, but lasers as a heat source offer some distinct advantages. With the selective heating attainable using high power lasers, good metallurgical bond of the clad layer, minimal dilution and typically, a very fine homogeneous microstructure can be obtained in the clad layer. This is a review of work in laser cladding using the 15 kW CO 2 laser. The authors discuss the ability of the laser clad surface to increase the high temperature oxidation resistance of a low-alloy carbon steel (4140). Examples of clads subjected to high- temperature thermal cycling of nickel-20% aluminum and TaC + 4140 clad low-alloy steel and straight high-temperature oxidation of Stellite 6-304L cladding on a 4140 substrate are given

The present work shows the behaviour of low carbon alloyed steels as AISI-SAE 8615, after a ferritic nitrocarburizing process. Nitrocarburizing takes place at 570 degree centigree for 3 h in an atmosphere by combustion of methanol and urea under different flow rates. Metallographic studies were performed by optical microscopy. Harness profiles were measured and carbon percentages were also analyzed by emission spectrometry in order to determine the extension of the nitrocarburizing process. Optimal flow conditions have been found. The influence of the flow rate on the nitrocarburizing layer thickness has been also studied. (Author) 12 refs

Tgs1 is the enzyme that converts m(7)G RNA caps to the 2,2,7-trimethylguanosine (TMG) caps characteristic of spliceosomal snRNAs. Fungi grow vegetatively without TMG caps, thereby raising the question of what cellular transactions, if any, are TMG cap-dependent. Here, we report that Saccharomyces cerevisiae Tgs1 methyltransferase activity is essential for meiosis. tgs1Δ cells are specifically defective in splicing PCH2 and SAE3 meiotic pre-mRNAs. The TMG requirement for SAE3 splicing is alleviated by two intron mutations: a UAUUAAC to UACUAAC change that restores a consensus branchpoint and disruption of a stem-loop encompassing the branchpoint. The TMG requirement for PCH2 splicing is alleviated by a CACUAAC to UACUAAC change restoring a consensus branchpoint and by shortening the PCH2 5' exon. Placing the SAE3 and PCH2 introns within a HIS3 reporter confers Tgs1-dependent histidine prototrophy, signifying that the respective introns are portable determinants of TMG-dependent gene expression. Analysis of in vitro splicing in extracts of TGS1 versus tgs1Δ cells showed that SAE3 intron removal was enfeebled without TMG caps, whereas splicing of ACT1 was unaffected. Our findings illuminate a new mode of tunable splicing, a reliance on TMG caps for an essential developmental RNA transaction, and three genetically distinct meiotic splicing regulons in budding yeast.

Technical Area (TA) 40 Building 15 (40-15) is an active firing site at Los Alamos National Laboratory. The weapons facility operations (WFO) group plans to build an enclosure over the site in 2017, so that test shots may be conducted year-round. The enclosure project is described in PRID 16P-0209. 40-15 is listed on LANL OSH-ISH’s beryllium inventory, which reflects the potential for beryllium in/on soils and building surfaces at 40-15. Some areas in and around 40-15 have previously been sampled for beryllium, but past sampling efforts did not achieve complete spatial coverage of the area. This Sampling and Analysis Plan (SAP) investigates the area surrounding 40-15 via 9 deep (≥1-ft.) soil samples and 11 shallow (6-in.) soil samples. These samples will fill the spatial data gaps for beryllium at 40-15, and will be used to support OSH-ISH’s final determination of 40-15’s beryllium registry status. This SAP has been prepared by the Environmental Health Physics program in consultation with the Industrial Hygiene program. Industrial Hygiene is the owner of LANL’s beryllium program, and will make a final determination with regard to the regulatory status of beryllium at 40-15.

We present extreme ultraviolet spectra of highly charged tungsten ions (W19 +-W32 + ) in the wavelength range of 15 -55 Å obtained with a compact electron-beam ion trap (CoBIT) and a grazing-incidence spectrometer at the National Institute for Fusion Science. The electron energy dependence of the spectra was investigated for electron energies from 490 to 1320 eV . Identification of the observed lines was aided by collisional-radiative (CR) modeling of CoBIT plasma. Good quantitative agreement was obtained between the CR-modeling results and the experimental observations. The ion charge dependence of the 6 g -4 f ,5 g -4 f ,5 f -4 d ,5 p -4 d , and 4 f -4 d transition wavelengths were measured.

For achieving ultrafast switching speed and minimizing dissipation losses, the spin-based data storage device requires a control on effective damping (α eff ) of nanomagnetic bits. Incorporation of interfacial antidamping spin orbit torque (SOT) in spintronic devices therefore has high prospects for enhancing their performance efficiency. Clear evidence of such an interfacial antidamping is found in Al capped Py(15 nm)/β-W(t W )/Si (Py = Ni 81 Fe 19 and t W = thickness of β-W), which is in contrast to the increase of α eff (i.e., damping) usually associated with spin pumping as seen in Py(15 nm)/β-W(t W )/Si system. Because of spin pumping, the interfacial spin mixing conductance (g ↑↓ ) at Py/β-W interface and spin diffusion length (λ SD ) of β-W are found to be 1.63(±0.02) × 10 18 m -2 (1.44(±0.02) × 10 18 m -2 ) and 1.42(±0.19) nm (1.00(±0.10) nm) for Py(15 nm)/β-W(t W )/Si (β-W(t W )/Py(15 nm)/Si) bilayer systems. Other different nonmagnetic capping layers (CL), namely, β-W(2 nm), Cu(2 nm), and β-Ta(2,3,4 nm) were also grown over the same Py(15 nm)/β-W(t W ). However, antidamping is seen only in β-Ta(2,3 nm)/Py(15 nm)/β-W(t W )/Si. This decrease in α eff is attributed to the interfacial Rashba like SOT generated by nonequilibrium spin accumulation subsequent to the spin pumping. Contrary to this, when interlayer positions of Py(15 nm) and β-W(t W ) is interchanged irrespective of the fixed top nonmagnetic layer, an increase of α eff is observed, which is ascribed to spin pumping from Py to β-W layer.

The Malarial Exported PFA0660w Is an Hsp40 Co-Chaperone of PfHsp70-x.

Full Text Available Plasmodium falciparum, the human pathogen responsible for the most dangerous malaria infection, survives and develops in mature erythrocytes through the export of proteins needed for remodelling of the host cell. Molecular chaperones of the heat shock protein (Hsp family are prominent members of the exportome, including a number of Hsp40s and a Hsp70. PFA0660w, a type II Hsp40, has been shown to be exported and possibly form a complex with PfHsp70-x in the infected erythrocyte cytosol. However, the chaperone properties of PFA0660w and its interaction with human and parasite Hsp70s are yet to be investigated. Recombinant PFA0660w was found to exist as a monomer in solution, and was able to significantly stimulate the ATPase activity of PfHsp70-x but not that of a second plasmodial Hsp70 (PfHsp70-1 or a human Hsp70 (HSPA1A, indicating a potential specific functional partnership with PfHsp70-x. Protein binding studies in the presence and absence of ATP suggested that the interaction of PFA0660w with PfHsp70-x most likely represented a co-chaperone/chaperone interaction. Also, PFA0660w alone produced a concentration-dependent suppression of rhodanese aggregation, demonstrating its chaperone properties. Overall, we have provided the first biochemical evidence for the possible role of PFA0660w as a chaperone and as co-chaperone of PfHsp70-x. We propose that these chaperones boost the chaperone power of the infected erythrocyte, enabling successful protein trafficking and folding, and thereby making a fundamental contribution to the pathology of malaria.

Case depth in SAE 1020 steel using barkhausen noise

Directory of Open Access Journals (Sweden)

Alessandra Drehmer

2013-01-01

Full Text Available The most widely used thermochemical process for surface hardening of steels is case hardening. Using several different heat treatments, martensitic surface layers were formed on SAE 1020 steel into which carbon had been diffused. Case depths were measured by traditional destructive techniques. Barkhausen noise measurements were made and both the RMS Barkhausen pulse envelope and the fast Fourier transform (FFT were obtained from numerical calculation. The FFT amplitudes, functions of frequency, were associated with distance from the sample surface using the skin depth equation δ = 1/ (πfσµ½ , where f is the frequency of the electromagnetic wave, s is the electrical conductivity, and µ is the magnetic permeability. We define a normalized power index (NPI which can be used to estimate case depths. The NPI is discussed in relation to the sample microstructure and it is shown that the case depth is most easily determined when the magnetic properties of the surface layer and core are substantially different.

Angelica archangelica Linn. is widely used in food and liquor preparations and also in Kashmiri folk medicine to reduce anxiety. We evaluated the anxiolytic effect of successive extracts of A. archangelica linn. (SAE) on rats tested in the elevated T-maze test (an animal model of generalized anxiety) at doses that exhibit antidepressant-like activity in humans. A. archangelica (1 kg) was subjected to successive extraction in a soxhlet apparatus with solvents [petroleum ether (40-60 degrees C), chloroform, ethyl acetate, methanol and decoction with water] in order of increasing polarity (yield: 6.9%, 7.3%, 5.1%, 11.88% and 8.2% w/w, respectively). SAE were evaluated for anxiolytic effects using the elevated T-maze and forced swimming tests in rats. Oral dosing of diazepam (1 mg/kg) and extracts (50, 100 and 200 mg/kg) clearly showed an anxiolytic-like profile in the elevated T-maze test: it increased one-way escape and decreased inhibitory avoidance on the first, third and seventh day. In the forced swimming test, imipramine and SAE showed antidepressant- and anxiolytic-like effects as reflected by increased climbing time, swimming time and decreased immobility time on the first, third and seventh day. Aqueous and methanol extracts showed the most, petroleum ether (40-60 degrees C) and chloroform intermediate, and ethyl acetate the least anxiolytic activity (*P<0.05, **P<0.01, ***P< 0.001) in both models. These results suggest the anti-anxiety activity of various extracts of A. archangelica and strongly justify its use in traditional Indian medicine for the treatment of anxiety.

Development of multi-element active aerodynamics for the formula sae car

Science.gov (United States)

Merkel, James Patrick

This thesis focuses on the design, development, and implementation of an active aerodynamics system on 2013 Formula SAE car. The aerodynamics package itself consists of five element front and rear wings as well as an under body diffuser. Five element wings produce significant amounts of drag which is a compromise between the cornering ability of the car and the acceleration capability on straights. The active aerodynamics system allows for the wing angle of attack to dynamically change their configuration on track based on sensory data to optimize the wings for any given scenario. The wings are studied using computational fluid dynamics both in their maximum lift configuration as well as a minimum drag configuration. A control system is then developed using an electro mechanical actuation system to articulate the wings between these two states.

Full Text Available The aim of this study was to explore the applicability of fast MR techniques to routine paediatric abdominopelvic MRI at 1.5 Tesla. “Controlled Aliasing in Parallel Imaging Results in Higher Acceleration-” (CAIPIRINHA- accelerated contrast-enhanced-T1w 3D FLASH imaging was compared to standard T1w 2D FLASH imaging with breath-holding in 40 paediatric patients and to respiratory-triggered T1w TSE imaging in 10 sedated young children. In 20 nonsedated patients, we compared T2w TIRM to fat-saturated T2w HASTE imaging. Two observers performed an independent and blinded assessment of overall image quality. Acquisition time was reduced by the factor of 15 with CAIPIRINHA-accelerated T1w FLASH and by 7 with T2w HASTE. With CAIPIRINHA and with HASTE, there were significantly less motion artefacts in nonsedated patients. In sedated patients, respiratory-triggered T1w imaging in general showed better image quality. However, satisfactory image quality was achieved with CAIPIRINHA in two sedated patients where respiratory triggering failed. In summary, fast scanning with CAIPIRINHA and HASTE presents a reliable high quality alternative to standard sequences in paediatric abdominal MRI. Paediatric patients, in particular, benefit greatly from fast image acquisition with less breath-hold cycles or shorter sedation.

Aerodynamic characteristics of a vehicle are important elements in its design and construction. A low drag coefficient brings significant fuel savings and increased engine power efficiency. In designing and developing vehicles trough computer simulation process to determine the vehicles aerodynamic characteristics are using dedicated CFD (Computer Fluid Dynamics) software packages. However, the results obtained by this faster and cheaper method, are validated by experiments in wind tunnels tests, which are expensive and were complex testing equipment are used in relatively high costs. Therefore, the emergence and development of new low-cost testing methods to validate CFD simulation results would bring great economic benefits for auto vehicles prototyping process. This paper presents the initial development process of a Formula SAE Student race-car prototype using CFD simulation and also present a measurement system based on low-cost sensors through which CFD simulation results were experimentally validated. CFD software package used for simulation was Solid Works with the FloXpress add-on and experimental measurement system was built using four piezoresistive force sensors FlexiForce type.

We experimentally demonstrate a W-band optical-wireless transmission system over 160-m wireless distance with a bit rate up to 40 Gb/s. The optical-wireless transmission system adopts optical polarization-division-multiplexing (PDM), multiple-input multiple-output (MIMO) reception and antenna polarization diversity. Using this system, we experimentally demonstrate the 2×2 MIMO wireless delivery of 20- and 40-Gb/s PDM quadrature-phase-shift-keying (PDM-QPSK) signals over 640- and 160-m wireless links, respectively. The bit-error ratios (BERs) of these transmission systems are both less than the forward-error-correction (FEC) threshold of 3.8×10-3.

Heat transfer characteristics of some oils used for engine cooling

International Nuclear Information System (INIS)

Abou-Ziyan, Hosny Z.

2004-01-01

This paper reports the results of an experimental investigation of heat transfer from a cast iron test specimen to engine oils under boiling conditions. The work is aimed at evaluating the thermal characteristics of some engine oils in contact with high temperature parts in internal combustion engines. Three mono-grade oils and two multi-grade oils are examined at heat fluxes from about 30 to more than 400 kW/m 2 for bulk temperatures of 40, 60, 80, 100, 125, 150 and 175 deg. C. The considered oils are analyzed and tested according to some ASTM standards to determine their additives concentration and to obtain some of their thermophysical properties. The results indicated that oil additives, oil properties and bulk temperatures have substantial effects on the oil characteristics. The boiling heat flux, for the best oil, rises by a factor of 1.65 as the bulk temperature decreases from 175 to 40 deg. C. The mono-grade oils produce superior heat transfer characteristics compared to those produced by multi-grade oils. The oil with the best additive concentrations produces boiling heat fluxes up to 4.44 times higher than those produced by some other oils. Comparing the results of the tested oils revealed that the oil that has the largest concentrations of boron, magnesium, phosphorus and zinc with low concentration of calcium yields the best heat transport characteristics among the other tested oils. These additives provide superior detergent and dispersant characteristics, reflected in the large alkalinity and low corrosivity of the oil. On the other side, calcium has a negative interaction with other additives and yields an adverse effect on heat transfer characteristics even when it exists in oil with large concentrations of boron, magnesium, phosphorus and zinc

The following report presents test descriptions and analysis results for multiple, stress level slug tests that were performed at selected test/depth intervals within three Operable Unit (OU) ZP-1 wells: 299-W11-43 (C4694/Well H), 299-W15-50 (C4302/Well E), and 299-W18-16 (C4303/Well D). These wells are located within south-central region of the Hanford Site 200-West Area (Figure 1.1). The test intervals were characterized as the individual boreholes were advanced to their final drill depths. The primary objective of the hydrologic tests was to provide information pertaining to the areal variability and vertical distribution of hydraulic conductivity with depth at these locations within the OU ZP-1 area. This type of characterization information is important for predicting/simulating contaminant migration (i.e., numerical flow/transport modeling) and designing proper monitor well strategies for OU and Waste Management Area locations.

It is considered the nonlinear algebras W(sl(4), sl(3)) and W(sl(3/1), sl(3)) and it is found their realizations in terms of currents spanning conformal linearizing algebras. The specific structure of these algebras, allows to construct realizations modulo null fields of the W 3 algebra that lies in the cosets W(sl(4), sl(3))/u(1) and W(sl(3/1), sl(3))/u(1). Such realizations exist for the following values of the W 3 algebra central charge: cw=-30, -40/7, -98/5, -2. The first two values are listed for the first time, whereas for the remaining values the new realizations get in terms of an arbitrary stress tensor and u(1) x sl(2) affine currents

Operational performance of the development of a 15 kW parabolic trough mid-temperature solar receiver/reactor for hydrogen production

International Nuclear Information System (INIS)

Hong, Hui; Liu, Qibin; Jin, Hongguang

2012-01-01

Highlights: ► A 15 kW solar chemical receiver/reactor for hydrogen production was developed. ► The solar thermochemical efficiency of the receiver/reactor was in the range of 20–28%. ► Hydrogen production exceeding 80% was achieved. ► The research results extend the application of mid-temperature solar thermal energy. -- Abstract: In this paper, we report the operational performance and energy conversion efficiency of a developed 15 kW solar chemical receiver/reactor for hydrogen production. A concentrated solar heat of around 200–300 °C was utilized to provide process heat to drive methanol steam reforming. A modified 15 kW direct-irradiation solar reactor coupled with a linear receiver positioned along the focal line of a one-axis parabolic trough concentrator was used. The experiments were conducted from 200 to 300 °C under a mean solar flux of 300–800 W/m 2 and a reactant feeding rate of 6 kg/h. Reactants were continuously fed, and the attained conversion rate of methanol was more than 70% at 700 W/m 2 . The typical solar thermochemical efficiency of solar thermal energy converted into chemical energy was in the 20–28% range. The overall energy efficiency of input solar power conversion into chemical energy reached up to 17% and may be further increased by improving solar field efficiency. Hydrogen production exceeding 80% was achieved. In addition, preliminary economic evaluation was performed, and methods for further improvement were proposed. This paper proves that solar hydrogen production is feasible by combining solar thermal energy with alternative fuel at around 200–300 °C, which is much lower than the temperature of other solar thermochemical processes. This may offer an economic approach to solar fuel production and extend the application of mid-temperature solar thermal energy.

We demonstrated an efficient and tunable single-longitudinal-mode Ho:YLF ring laser based on Faraday effect for application to measure atmospheric carbon dioxide (CO 2 ). Single-longitudinal-mode power at 2051.65 nm achieved 528 mW with the slope efficiency of 39.5% and the M 2 factor of 1.07, and the tunable range of about 178 GHz was obtained by inserting a Fabry-Perot (F-P) etalon with the thickness of 0.5 mm. In addition, the maximum single-longitudinal-mode power reached 1.5 W with the injected power of 528 mW at 2051.65 nm by master oscillator power amplifier (MOPA) technique. High efficiency and tunable single-longitudinal-mode based on Faraday effect around 2 μm has not been reported yet to the best of our knowledge.

Experimental results are reported on the distribution of arrival time intervals between pairs of atmospheric muons detected at 40 m.w.e. underground and generated in interactions of primary nuclei with average energy about 600 GeV. A total number of 72,220 single muons was recorded with a total frequency of 7.1 muons per second, in good agreement with previous measurements at the same depth 2 x 10 to the -6th random coincidences per second were obtained, a negligible value. The temporal analysis showed very good agreement between data and stochastic predictions. It is concluded that the overabundance of short-delayed cosmic ray particles, if real at higher energies, is not present either at the lower energies of single muons or at the intermediate energies of muon pairs detected in the experiment.

Bindal, Shruti; Gupta, Rani

2017-02-07

Microbial γ-glutamyl transpeptidases (GGTs) have been exploited in biotechnological, pharmaceutical, and food sectors for the synthesis of various γ-glutamyl compounds. But, till date, no bacterial GGTs are commercially available in the market because of lower levels of production from various sources. In the current study, production of GGT from Bacillus licheniformis ER15 was investigated to achieve high GGT titers. Hyperproduction of GGT from B. licheniformis ER15 was achieved with 6.4-fold enhancement (7921.2 ± 198.7 U/L) by optimization of culture medium following one-variable-at-a-time strategy and statistical approaches. Medium consisting of Na 2 HPO 4 : 0.32% (w/v); KH 2 PO 4 : 0.15% (w/v); starch: 0.1% (w/v); soybean meal: 0.5% (w/v); NaCl: 4.0% (w/v), and MgCl 2 : 5 mM was found to be optimal for maximum GGT titers. Maximum GGT titers were obtained, in the optimized medium at 37°C and 200 rpm, after 40 h. It was noteworthy that GGT production was a linear function of sodium chloride concentration, as observed during response surface methodology. While investigating the role of NaCl on GGT production, it was found that NaCl drastically decreased subtilisin concentration and indirectly increasing GGT recovery. B. licheniformis ER15 is proved to be a potential candidate for large-scale production of GGT enzyme and its commercialization.

The U.S. Department of Energy, National Nuclear Security Administration, Los Alamos Field Office (Field Office) proposes to upgrade and enclose Building 15 at Technical Area (TA) 40, Los Alamos National Laboratory. Building TA-40-15, a Cold War-era firing site, was determined eligible for listing in the National Register of Historic Places (Register) in DX Division’s Facility Strategic Plan: Consolidation and Revitalization at Technical Areas 6, 8, 9, 14, 15, 22, 36, 39, 40, 60, and 69 (McGehee et al. 2005). Building TA-40-15 was constructed in 1950 to support detonator testing. The firing site will be enclosed by a steel building to create a new indoor facility that will allow for year-round mission capability. Enclosing TA-40-15 will adversely affect the building by altering the characteristics that make it eligible for the Register. In compliance with Section 106 of the National Historic Preservation Act of 1966, as amended, the Field Office is initiating consultation for this proposed undertaking. The Field Office is also requesting concurrence with the use of standard practices to resolve adverse effects as defined in the Programmatic Agreement among the U.S. Department of Energy, National Nuclear Security Administration, Los Alamos Field Office, the New Mexico State Historic Preservation Office and the Advisory Council on Historic Preservation Concerning Management of the Historic Properties at Los Alamos National Laboratory, Los Alamos, New Mexico.

This paper aims at analyzing the effects of the roller pre-straightening of wire-rods on residual stress distributions in SAE 1045 steel bars. The combined drawing process is used in industrial production of bars in order to obtain a good surface quality and improved mechanical properties complying with specifications of the final products. In this process, prior to the drawing step, a roller straightening of the steel wire-rod is essential, because it provides the minimum straightness necessary for drawing. Metallographic analysis and hardness test were done for selected samples after different processing steps. Also, residual stress analysis of pre-straightened wire-rods by X-ray diffraction and neutron diffraction were carried out. The hardness tests show higher values near the surface and lower in the center of the wire-rod. Besides, the residual stresses results show a big inhomogeneity from one peripheral position to another and also in the evaluated cross section. (author)

2015-09-01

Full Text Available Diamond like carbon (DLC coatings mitigate aluminium adhesion and reduce friction under the ambient conditions but their tribological behaviour under lubricated sliding need to be further investigated. In this study, tribological tests were performed to evaluate the friction and wear characteristics of W-DLC and H-DLC coatings sliding against an aluminium alloy (319 Al under unlubricated (40 % RH and lubricated sliding conditions. For unlubricated sliding, coefficient of friction (COF values of H-DLC and W-DLC were 0.15 and 0.20. A lower COF value of 0.11 was observed when W-DLC was tested using lubricant oil incorporating sulphur while the H-DLC’s COF remained almost unchanged. The mechanisms responsible for the low friction of W-DLC observed during lubricated sliding were revealed by studying the compositions of the coating surfaces and the transfer layers formed on 319 Al. Micro-Raman spectroscopy indicated that the transfer layers formed during lubricated sliding of W-DLC incorporated tungsten disulphide (WS2.

In response to chromosomal double-strand breaks (DSBs), eukaryotic cells activate the DNA damage checkpoint, which is orchestrated by the PI3 kinase-like protein kinases ATR and ATM (Mec1 and Tel1 in budding yeast). Following DSB formation, Mec1 and Tel1 phosphorylate histone H2A on serine 129 (known as γ-H2AX). We used caffeine to inhibit the checkpoint kinases after DSB induction. We show that prolonged phosphorylation of H2A-S129 does not require continuous Mec1 and Tel1 activity. Unexpectedly, caffeine treatment impaired homologous recombination by inhibiting 5′ to 3′ end resection, independent of Mec1 and Tel1 inhibition. Caffeine treatment led to the rapid loss, by proteasomal degradation, of both Sae2, a nuclease that plays a role in early steps of resection, and Dna2, a nuclease that facilitates one of two extensive resection pathways. Sae2's instability is evident in the absence of DNA damage. A similar loss is seen when protein synthesis is inhibited by cycloheximide. Caffeine treatment had similar effects on irradiated HeLa cells, blocking the formation of RPA and Rad51 foci that depend on 5′ to 3′ resection of broken chromosome ends. Our findings provide insight toward the use of caffeine as a DNA damage-sensitizing agent in cancer cells. PMID:26019182

Indigenous bacterial strain Pseudomonas balearica SAE1, tolerant to e-waste toxicity was isolated from an e-waste recycling facility Exigo Recycling Pvt. Ltd., India. Toxicity tolerance of bacterial strain was analyzed using crushed (particle size ≤150 µm) waste computer printed circuit boards (PCBs)/liter (L) of culture medium. The EC 50 value for SAE1 was 325.7 g/L of the e-waste pulp density. Two-step bioleaching was then applied to achieve the dissolution of gold (Au) and silver (Ag) from the e-waste. To maximize precious metal dissolution, factors including pulp density, glycine concentration, pH level, and temperature were optimized. The optimization resulted in 68.5 and 33.8% of Au and Ag dissolution, respectively, at a pH of 9.0, a pulp density of 10 g/L, a temperature of 30 °C, and a glycine concentration of 5 g/L. This is the first study of Au and Ag bioleaching using indigenous e-waste bacteria and its analysis to determine e-waste toxicity tolerance.

The influence of hydrogen charging into a quenched and tempered boron steel membrane electrode (SAE 10B22) was studied using borate buffer (pH 8.4) and NaOH solutions (pH 12.7), with or without the addition of 0.01 M EDTA. At the hydrogen input side, hydrogen charging influenced cyclic voltammograms increasing the anodic charge of iron(II) hydroxide formation, and decreasing the donor density of passive films. These results suggest that the hydrogen ingress caused instability of metallic surface, increasing the surface area activity

Sepsis-associated encephalopathy (SAE) is associated with an increased rate of morbidity and mortality. It is not understood what the exact mechanism is for the brain dysfunction that occurs in septic patients, but brain inflammation and oxidative stress are a possible theory. Such events can occur through the alteration of molecules that perpetuate the inflammatory response. Thus, it is possible to postulate that CD40 may be involved in this process. The aim of this work is to evaluate the role of CD40-CD40L pathway activation in brain dysfunction associated with sepsis in an animal model. Microglia activation induces the upregulation of CD40-CD40L, both in vitro and in vivo. The inhibition of microglia activation decreases levels of CD40-CD40L in the brain and decreases brain inflammation, oxidative damage and blood brain barrier dysfunction. Despite this, anti-CD40 treatment does not improve mortality in this model. However, it is able to improve long-term cognitive impairment in sepsis survivors. In conclusion, there is a major involvement of the CD40-CD40L signaling pathway in long-term brain dysfunction in an animal model of sepsis.

Microstructural data of neutron irradiated Tungsten (W) such as size and number density of voids and precipitates obtained by W up to 1.5dpa irradiation in the temperature range of 400-800degC were compiled quantitatively. Nucleation and growth process of these defects were clarified and a qualitative prediction of the damage structure development and hardening of W in fusion reactor environments were made taking into account the solid transmutation effects for the first time. To improve recrystallization behavior and low temperature embrittlement, grain refined-W alloys were fabricated by K- or La-doping method. Rhenium addition to the grain refining process was also examined to improve mechanical properties. Characterizations of unirradiated materials were performed. (author)

Full Text Available We present in this work a first assessment of the imaging and topographic mapping capabilities of the InSAeS4 system, which is a single-pass interferometric airborne X-Band Synthetic Aperture Radar (SAR. In particular, we first provide a brief description of the InSAeS4 sensor. Then, we discuss the results of our analysis on the SAR and interferometric SAR products relevant to the first flight-test campaign. More specifically, we have exploited as reference the GPS measurements relevant to nine Corner Reflectors (CRs deployed over the illuminated area during the campaign and a laser scanner Digital Elevation Model (DEM. From the analysis carried out on the CRs we achieved a mean geometric resolution, for the SAR products, of about 0.14 m in azimuth and 0.49 m in range, a positioning misalignment with standard deviation of 0.07 m in range and 0.08 m in azimuth, and a height error with standard deviation of 0.51 m. From the comparison with the laser scanner DEM we estimated a height error with standard deviation of 1.57 m.

This work describes the effect of austempering heat treatment on microstrcuture and mechanical properties of SAE 9260 steel. Steel samples, austenitized at 900 °C for one hour, were isothermally heat treated in the temperature range 300,325 and 350 °C for different times. Microstructural characterization was carried out using optical and scanning electron microscopes. The microstructure of the austempered samples consisted of bainitic ferrite and retained austenite. The volume fraction of retained austenite was determined using X-ray diffraction. Isothermal heat treatment at 350 °C for 20 min, resulted in a retained austenite content of around 38% in the microstructure. Increase in isothermal transformation temperature led to an increase in the fraction of retained austenite. Also, good combination of strength and ductility was obtained in the samples with increased amounts of retained austenite.

Photodynamic inactivation (PDI) involves the combined use of light and a photosensitizer, which, in the presence of oxygen, originates cytotoxic species capable of inactivating bacteria. Since the emergence of multi-resistant bacterial strains is becoming an increasing public health concern, PDI becomes an attractive choice. The aim of this work was to study the differential susceptibility to Toluidine blue (TB) mediated PDI (TB-PDI) of S. aureus mutants (RN6390 and Newman backgrounds) for different key regulators of virulence factors related to some extent to oxidative stress. Complete bacteria eradication of planktonic cultures of RN6390 S. aureus photosensitized with 13μM TB was obtained upon illumination with a low light dose of 4.2J/cm 2 from a non-coherent light source. Similarly, complete cell death was achieved applying 1.3μM TB and 19J/cm 2 light dose, showing that higher light doses can lead to equal cell death employing low photosensitizer concentrations. Interestingly, RN6390 in planktonic culture responded significantly better to TB-PDI than the Newman strain. We showed that deficiencies in rsbU, mgrA (transcription factors related to stress response) or agr (quorum sensing system involved in copper resistance to oxidative stress) did not modify the response of planktonic S. aureus to PDI. On the other hand, the two component system sae impaired the response to TB-PDI through a mechanism not related to the Eap adhesin. More severe conditions were needed to inactivate S. aureus biofilms (0.5mM TB, 157J/cm 2 laser light). In mutant sae biofilms, strain dependant differential susceptibilities are not noticed.

Full Text Available Em substituição aos óleos minerais, os óleos biodegradáveis vêm proporcionando uma grande alternativa ao mercado, uma vez que o mesmo diminui os impactos ambientais. Com a finalidade de avaliar o desempenho do óleo de rícino (refinado e bruto e o óleo de coco comparando-os com os óleos minerais SAE 20W50 SJ e W40, realizaram-se ensaios tribológicos de desgaste na configuração pino-contra-cilindro de aço AISI 52100. As superfícies das amostras metálicas foram confeccionadas por torneamento e lixamento, utilizando-se lixas de diferentes granulometrias, seguidas por limpeza com banho ultrassônico e pesagem antes e após a realização dos ensaios. Os corpos-de-prova foram analisados antes dos ensaios no microscópio óptico. A dureza do aço AISI 52100 foi medida utilizando-se um durômetro Rockwell. O óleo foi caracterizado através de ensaios de densidade e tensão superficial (Souza et. al., 2007. A eficiência da ação do lubrificante foi avaliada através da taxa de desgaste calculada para as amostras utilizando-se a equação de Archard e através da microscopia eletrônica de varredura (MEV. Segundo resultados da taxa de desgaste, os óleos vegetais de rícino e coco obtiveram valores de 88,89 % e 33,33 % menores que para os óleos W40 e SAE 20W50 SJ, respectivamente. Sendo assim, os óleos vegetais possuem propriedades tribológicas equivalentes e até superiores às dos óleos minerais estudados.

In an automobile, the rear upright are used to provide a physical mounting and links the suspension arms to the hub and wheel assembly. In this work, static structural and shape optimization analysis for rear upright for UniMAP’s Formula SAE racing car had been done using ANSYS software with the objective to reduce weight while maintaining the structural strength of the vehicle upright. During the shape optimization process, the component undergoes 25%, 50% and 75 % weight reduction in order to find the best optimal shape of the upright. The final design of the upright is developed considering the weight reduction, structural integrity and the manufacturability. The final design achieved 21 % weight reduction and is able to withstand several loads.

1990-01-01

Impregnated tungsten cathodes half-coated with Re/W (or Os/W) alloy and Os Re W alloy at right angles were studied to compare the effects of Os Re W alloy coatings on the electron emission and emission mechanisms. Constant surface metal compositions of 32% Os--29% Re--39% W and 35% Os--26% Re--39% W were obtained from the activated surfaces initially coated with 40% Os--40% Re--20% W and 35% Os--45% Re--20% W alloys, respectively. Thermionic emission microscopy measurements showed that the Os Re W alloy-coated surface gives an average effective work function of 0.29, 0.08, and 0.03 eV lower than the uncoated, Re/W and Os/W alloy-coated surfaces. An effective work function of 1.73 eV was obtained from an activated Os Re W alloy surface. Auger studies exhibited a smaller BaO coverage and a higher barium coverage in excess of BaO stoichiometry on the Os Re W alloy-coated surface compared to the uncoated, Re/W and Os/W alloy-coated surfaces

Full Text Available This research studies the effects of W/B ratios and palm oil fuel ash (POFA on compressive strength, water permeability, and chloride resistance of concrete. POFA was ground until the particles retained on sieve number 325 were less than 5% by weight. POFA was used to partially replace OPC at rates of 15, 25, and 35% by weight of binder. The water to binder (W/B ratios of concrete were 0.40 and 0.50. The compressive strength, water permeability, and chloride resistance of concrete were investigated up to 90 days. The results showed that POFA concrete with W/B ratio of 0.40 had the compressive strengths ranging from 45.8 to 55.9 MPa or 82–94% of OPC concrete at 90 days, while POFA concrete with W/B ratio of 0.50 had the compressive strengths of 33.9–41.9 MPa or 81–94% of OPC concrete. Furthermore, the compressive strength of concrete incorporation of ground POFA at 15% was the same as OPC concrete. The water permeability coefficient and the chloride ion penetration of POFA concrete were lower than OPC concrete when both types of concrete had the same compressive strengths. The findings also indicated that water permeability and chloride ion penetration of POFA concrete were significantly reduced compared to OPC concrete.

2013-01-01

Solar-pumped solid-state lasers are promising for renewable extreme-temperature material processing. Here, we report a significant improvement in solar laser collection efficiency by pumping the most widely used Nd:YAG single-crystal rod through a heliostat–parabolic mirror system. A conical-shaped fused silica light guide with 3D-CPC output end is used to both transmit and compress the concentrated solar radiation from the focal zone of a 2 m diameter parabolic mirror to a 5 mm diameter Nd:YAG rod within a conical pump cavity, which enables multi-pass pumping through the laser rod. 40 W cw laser power is measured, corresponding to 13.9 W m −2 record-high collection efficiency for the solar laser pumped through a heliostat–parabolic mirror system. 2.9% slope efficiency is fitted, corresponding to 132% enhancement over that of our previous pumping scheme. A 209% reduction in threshold pump power is also registered. (paper)

Sepsis-associated encephalopathy (SAE) is associated with an increased rate of morbidity and mortality. It is not understood what the exact mechanism is for the brain dysfunction that occurs in septic patients, but brain inflammation and oxidative stress are a possible theory. Such events can occur through the alteration of molecules that perpetuate the inflammatory response. Thus, it is possible to postulate that CD40 may be involved in this process. The aim of this work is to evaluate the role of CD40–CD40L pathway activation in brain dysfunction associated with sepsis in an animal model. Microglia activation induces the upregulation of CD40–CD40L, both in vitro and in vivo. The inhibition of microglia activation decreases levels of CD40–CD40L in the brain and decreases brain inflammation, oxidative damage and blood brain barrier dysfunction. Despite this, anti-CD40 treatment does not improve mortality in this model. However, it is able to improve long-term cognitive impairment in sepsis survivors. In conclusion, there is a major involvement of the CD40–CD40L signaling pathway in long-term brain dysfunction in an animal model of sepsis. PMID:25822797

High-power, high-brightness diode lasers have been pursued for many applications including fiber laser pumping, materials processing, solid-state laser pumping, and consumer electronics manufacturing. In particular, 915 nm - and 976 nm diodes are of interest as diode pumps for the kilowatt CW fiber lasers. As a result, there have been many technical thrusts for driving the diode lasers to have both high power and high brightness to achieve high-performance and reduced manufacturing costs. This paper presents our continued progress in the development of high brightness fiber-coupled product platform, nLIGHT element®. In the past decade, the power coupled into a single 105 μm and 0.15 NA fiber has increased by over a factor of ten through improved diode laser brightness and the development of techniques for efficiently coupling multiple emitters. In this paper, we demonstrate further brightness improvement and power-scaling enabled by both the rise in chip brightness/power and the increase in number of chips coupled into a given numerical aperture. We report a new chip technology using x-REM design with brightness as high as 4.3 W/mm-mrad at a BPP of 3 mm-mrad. We also report record 315 W output from a 2×12 nLIGHT element with 105 μm diameter fiber using x-REM diodes and these diodes will allow next generation of fiber-coupled product capable of 250W output power from 105 μm/0.15 NA beam at 915 nm.

The three dimensional ion implantation technology (3DII) is one of the methods of improving the tribological characteristics and resistance to hydrogen embrittlement processes in metals. In this report, some results concerning the resistance effect of nitrogen ion implantation to oxidation of the sample, made of AISI/SAE 1020 steel, are given. The nitrogen ions were implanted in the discharge chamber of the JUPITER reactor. Both the treated and untreated samples were tested through potential-static measurements, which permitted to determine the corrosion current, the slopes that characterise the braking level of anode and cathode reactions. The polarization resistance near the corrosion potential is calculated. The results of the study encourage to consider the nitrogen ion implantation in high voltage and low pressure discharges as one of the methods of anticorrosive protection which do not change the geometric configuration of the treated steel pieces.

The influence of alkali fatty acids on the properties and the stability of parenteral O/W emulsions modified with solutol HS 15.

Science.gov (United States)

Buszello, K; Harnisch, S; Müller, R H; Müller, B W

2000-03-01

Arachis oil based parenteral O/W emulsions were prepared using soya bean phosphatidylcholine (SPC) and different combinations of co-emulsifiers containing polyethylene glycol fatty acid esters (Solutol HS 15) and alkali fatty acids (sodium laurate, sodium stearate). The parameters measured were droplet size (both by photon correlation spectroscopy and laser diffractometry), pH and zeta potential. All emulsions were subjected to autoclaving. The addition of polyethylene glycol 12-hydroxy stearate (Solutol HS 15) led to a significant decrease of mean oil droplet size. For long-term stability the amount added turned out to be the most important factor. With increased amounts of Solutol HS 15 the packing density of the emulsifier layer and the zeta potential decreased leading to instability. The optimum load of Solutol HS 15 was found to be 15 micromol/ml. Alkali fatty acids markedly improved the physical stability of the emulsions. Improved stability properties conferred to emulsions by alkali fatty acids could be attributed to the zeta potential increase even in the presence of Solutol HS 15. Consequently a mixed emulsifier film was established in which the ionized fatty acids determined the interface charge. In addition to this a strengthening of the molecular interactions occurring between phospholipid and Solutol HS 15 emulsifier in the presence of ionized fatty acids at the O/W interface can be assumed (L. Rydhag, The importance of the phase behaviour of phospholipids for emulsion stability, Fette Seifen Anstrichm. 81 (1979) 168-173). Different co-emulsifier mixtures were shown to have a pronounced impact on the plasma protein adsorption onto emulsion droplets.

Honma, K.; Handa, K.; Akinaga, W.; Doi, M.; Matsuzaki, O.

This paper describes the design and the performance of the S-band low noise amplifier and the S-band high power amplifier that have been developed for the Usuda Deep Space Station of the Institute of Space and Astronautical Science (ISAS), Japan. The S-band low noise amplifier consists of a helium gas-cooled parametric amplifier followed by three-stage FET amplifiers and has a noise temperature of 8 K. The high power amplifier is composed of two 28 kW klystrons, capable of transmitting 40 kW continuously when two klystrons are combined. Both subsystems are operating quite satisfactorily in the tracking of Sakigake and Suisei, the Japanese interplanetary probes for Halley's comet exploration, launched by ISAS in 1985.

Zastosowanie programów komputerowych w rehabilitacji neuropsychologicznej dysfunkcji poznawczych u pacjentów ze stwardnieniem rozsianym

Full Text Available W obrazie klinicznym stwardnienia rozsianego (łac. sclerosis multiplex, SM na funkcjonowanie chorych wpływają – poza objawami neurologicznymi – współwystępujące objawy neuropsychologiczne, do których zalicza się zaburzenia emocjonalne i dysfunkcje poznawcze oraz czynniki osobowościowe. Dysfunkcje w sferze procesów uwagi, funkcji wykonawczych czy pamięci mają wpływ na zmniejszenie zdolności adaptacyjnych, które są kluczowe dla jakości życia chorych. W badaniach dużych grup klinicznych udowodniono obecność dysfunkcji poznawczych u 40–65% pacjentów. Najczęściej na SM zapadają osoby młode, u których dysfunkcje ruchowe i zaburzenia poznawcze mogą utrudniać codzienne funkcjonowanie, a często też stają się przeszkodą w podejmowaniu zadań życiowych. Dlatego też istnieje potrzeba opracowania nowych i skutecznych programów rehabilitacyjnych dla tej grupy chorych. Rehabilitacja neuropsychologiczna pacjentów z SM obejmuje różnego rodzaju oddziaływania, których celem jest leczenie dysfunkcji poznawczych. W pracy neuropsychologa coraz częściej jako narzędzie terapeutyczne wykorzystuje się programy komputerowe służące do treningów poznawczych. Podstawą dla tego typu oddziaływań są dowody świadczące o zmianach neuroplastycznych u osób ze stwardnieniem rozsianym. Największe efekty terapeutyczne osiąga się jednak dzięki współpracy zespołu interdyscyplinarnego, w którego skład powinni wchodzić neurolog, psychiatra, neuropsycholog oraz rehabilitant. W Polsce uzyskanie takiej pomocy przez pacjentów z SM jest nadal bardzo trudne. Przykładem obrazującym skuteczne zastosowanie rehabilitacji neuropsychologicznej za pomocą programów komputerowych jest studium przypadku chorego ze stwardnieniem rozsianym.

Full Text Available Jedną z bardziej interesujących części zbiorów Biblioteki Głównej UMK jest znajdujący się tam od niedawna depozyt Biblioteki Katedry Filologii Germańskiej. Jego geneza łączy się nierozerwalnie z dziejami Uniwersytetu oraz samej Katedry, kształcącej germanistów już od ponad 40 lat. Celem autora jest poznanie tego księgozbioru, zarówno pod względem jego proweniencji, jak i wartości dla germanistów i historyków. Ważną kwestia jest ustalenie głównych twórców biblioteki germanistycznej po II wojnie światowej, jak również po reaktywacji Katedry Filologii Germańskiej w 1969 r. Depozyt Katedry Filologii Germańskiej w BG UMK liczy 7627 tomów. Już sam fakt sposobu jego powstawania, szczególnie po II wojnie światowej, głównie drogą zabezpieczania zbiorów poniemieckich, a ponadto zakupów i darów, musiał wpłynąć na różnorodność gatunkową oraz proweniencję. W depozycie daje się zauważyć mnogość ośrodków, z których nastąpiło rozproszenie zbiorów bibliotecznych. W ujęciu geograficznym jest to obszar od Greifswaldu na zachodzie po Królewiec na wschodzie. Od Gdańska i Słupska na północy aż po Dzierżoniów (Reichenbach, Świdnicę (Schweidnitz oraz Wrocław na południu. W księgozbiorze tym można wyróżnić prozę i poezję niemiecką ze szczególnym uwzględnieniem twórców z XIX i pierwszej połowy XX w., następnie opracowania krytyczne literatury niemieckiej, słowniki języka niemieckiego w tym rozmaitych jego dialektów.Ustalenia niewątpliwie autora potwierdzają tezę, że charakteryzowany księgozbiór ma niewątpliwie nie tylko ciekawą proweniencję, często udokumentowaną znakami własnościowymi w postaci pięknych exlibrisów lub superexlibrisów, ale przede wszystkim znaczną wagę dla filologów germańskich. Może bowiem stanowić cenną pomoc naukową dla badań językoznawczych i historycznych (historia Niemiec i Skandynawii. Kryje on jeszcze, pomimo powyższych ustale

Influence of pH, temperature and thermal treatment on site corrosion of SAE 304 steel in chlorinated solutions

International Nuclear Information System (INIS)

Konrad, I.B.

1982-01-01

The electrochemical behaviour and fracture morphology of homogenized and sensitized type SAE 304 stainless steel U bent specimens, in 3% NaCl solution, at pH=2.0 and pH=7.0 both at room temperature and 100 0 C was studied. Polarization curves, galvanostatic and potentiostatic experiments were run. It could be observed that high temperature and low pH favour transgranular cracking and longer sensitization times lower fracture time and tend to give rise to intergranular fracture. Light sensitization can produce transgranular cracking even at room temperature, when the homogenized alloy does not present stress-corrosion cracking for the same condition. (Author) [pt

The results obtained produced good internal consistency for all the temperatures studied. Once E 0 was determined, the mean ionic activity coefficients for LiCl, the Gibbs free energy of transfer from the water to (PEG 4000 + water), and the primary LiCl hydration number were calculated.

Physical state of implanted W in copper

International Nuclear Information System (INIS)

Borders, J.A.; Cullis, A.G.; Poate, J.M.

1975-01-01

Transmission electron microscopy and 4 He ion channeling measurements were combined to investigate the physical state of implanted W in copper. For 60 0 K implantations of 2 x 10 15 W cm -2 , W is found to be 100 percent substitutional and is still 90 percent substitutional for a dose of 10 16 W cm -2 . Implantation of 10 17 W cm -2 produces a thin disordered surface layer of W and Cu with the W occupying no regular lattice site. On annealing to 600 0 C, W precipitates are formed with dimensions of a few hundred A and certain preferred orientations in the Cu lattice. (auth)

Development of Zn50 Brazing Alloy for Joining Mild Steel to Mild Steel (SAE1018

Directory of Open Access Journals (Sweden)

S.C. Nwigbo

2014-09-01

Full Text Available This work has developed new brazing alloys for joining mild steel to mild steel (SAE1018 at a lower temperature. The alloys blends and error analysis were done by experimental design software (Design Expert 8.0.7.1. Design of experiments was done by Scheffe quadratic mixture method. The liquidus temperatures were predicted by calculation of phase diagrams of the alloying metals. The brazing alloys were produced by gravity technique and melted using silicon carbide graphite crucible. The quality of the brazing alloys was analyzed by optical microscopy (OM, atomic absorption spectroscopy (AAS and fourier transform infrared spectroscopy (FT-IR. Brazed joints were produced by torch method with a commercial flux. Brazing temperatures (liquidus were tracked by a digital infrared/laser pyrometer. Some mechanical properties studied were tensile strength and hardness. Finally, brazed joints produced from the developed brazing alloys were compared to that produced from muntz brass. Six (6 brazing alloys were successfully developed. Zinc and manganese were the main components, to which were added; 3 to 4 %wt silver and 11 to15 %wt modifying element. The microstructure showed a typical eutectic structure with zinc-rich phase distributed uniformly in the matrix with a combination of different sizes of dendrite, rounded blocks of compounds and hypoeutectic structures. AAS results indicated minimal out-gassing of zinc and FT-IR results indicated very low presence of atmospheric gas. The range of brazing temperature for best results was recorded from 690.90 to 735.10 0C. The joints produced from the developed brazing alloys had acceptable strengths with improved stress-strain behaviour compared to muntz brass.

Probing strongly interacting electroweak dynamics through W+W-/ZZ ratios at future e+e- colliders

Barger, V.; Cheung, K.; Han, T.; Phillips, R.J.N.

1995-01-01

We point out that the ratio of W + W - →W + W - and W + W - →ZZ cross sections is a sensitive probe of the dynamics of electroweak symmetry breaking, in the c.m. energy region √s WW approx-gt 1 TeV where vector boson scattering may well become strong. We suggest ways in which this ratio can be extracted at a 1.5 TeV e + e - linear collider, using W ± ,Z→jj hadronic decays and relying on dijet mass resolution to provid statistical discrimination between W ± and Z. WW fusion processes studied here are unique for exploring scalar resonances of mass of about 1 TeV and are complementary to studies via the direct channel e + e - →W + W - for the vector and nonresonant cases. With an integrated luminosity of 200 fb -1 , the signals obtained are statistically significant. A comparision with a study of the e - e - →ννW - W - process is made. Enhancements of the signal rate from using a polarized electron beam, or at a 2 TeV e + e - linear colider and possible higher energy μ + μ - colliders, are also presented

2014-01-01

In order to explore local large-scale structures and velocity fields, accurate galaxy distance measures are needed. We now extend the well-tested recipe for calibrating the correlation between galaxy rotation rates and luminosities—capable of providing such distance measures—to the all-sky, space-based imaging data from the Wide-field Infrared Survey Explorer (WISE) W1 (3.4 μm) and W2 (4.6 μm) filters. We find a correlation of line width to absolute magnitude (known as the Tully-Fisher relation, TFR) of M W1 b,i,k,a =−20.35−9.56(log W mx i −2.5) (0.54 mag rms) and M W2 b,i,k,a =−19.76−9.74(log W mx i −2.5) (0.56 mag rms) from 310 galaxies in 13 clusters. We update the I-band TFR using a sample 9% larger than in Tully and Courtois. We derive M I b,i,k =−21.34−8.95(log W mx i −2.5) (0.46 mag rms). The WISE TFRs show evidence of curvature. Quadratic fits give M W1 b,i,k,a =−20.48−8.36(log W mx i −2.5)+3.60(log W mx i −2.5) 2 (0.52 mag rms) and M W2 b,i,k,a =−19.91−8.40(log W mx i −2.5)+4.32(log W mx i −2.5) 2 (0.55 mag rms). We apply an I-band –WISE color correction to lower the scatter and derive M C W1 =−20.22−9.12(log W mx i −2.5) and M C W2 =−19.63−9.11(log W mx i −2.5) (both 0.46 mag rms). Using our three independent TFRs (W1 curved, W2 curved, and I band), we calibrate the UNION2 Type Ia supernova sample distance scale and derive H 0 = 74.4 ± 1.4(stat) ± 2.4(sys) km s –1 Mpc –1 with 4% total error.

Cyclic deformation behaviour of a normalized steel SAE 4140 in shear strain-controlled torsion is characterized by cyclic softening and cyclic hardening. If mean shear stresses are superimposed to an alternating shear stress, cycle-dependent creep occurs, and the number of cycles to failure decreases. In shear strain-controlled torsional loading, mean stresses are observed to relax nearly to zero within a few cycles. Fatigue life is not influenced by mean shear strains. (orig.).

Prostate photovaporisation with Greenlight laser for the surgical treatment of benign prostate hyperplasia has rapidly evolve to the new XPS 180W. We have previously demonstrated the safety and efficacy of the HPS 120W. The aim of this study was to assess the functional and safety results, with a year of follow-up, of photovaporisation using the XPS 180W laser compared with its predecessor. A cohort study was conducted with a series of 191 consecutive patients who underwent photovaporisation between 1/2008 and 5/2013. The inclusion criteria were an international prostate symptom score (IPSS) >15 after medical failure, a prostate volume <80 cm(3) and a maximum flow <15 mL/s. We assessed preoperative and intraoperative variables (energy used, laser time and total surgical time), complications, catheter hours, length of stay and functional results (maximum flow, IPSS, prostate-specific antigen and prostate volume) at 3, 6 and 12 months. We analysed the homogeneity in preoperative characteristics of the 2 groups through univariate analysis techniques. The postoperative functional results were assessed through an analysis of variance of repeated measures with mixed models. A total of 109 (57.1%) procedures were performed using HPS 120W, and 82 (42.9%) were performed using XPS. There were no differences between the preoperative characteristics. We observed significant differences both in the surgical time and effective laser time in favour of the XPS system. This advantage was 11% (48 ± 15.7 vs. 53.8 ± 16.2, p<.05) and 9% (32.8 ± 11.7 vs. 36 ± 11.6, p<.05), respectively. There were no statistically significant differences in the rest of the analysed parameters. The technical improvements in the XPS 180W system help reduce surgical time, maintaining the safety and efficacy profile offered by the HPS 120W system, with completely superimposable results at 1 year of follow-up.

The Saar colliery with an output of 15.000 t saleable output/day is one of the most efficient mines of DSK. In view of the northward migration of the faces and the incorporation of the new Primsmulde field it was necessary to optimise the existing infrastructure of the colliery and adapt it to the new situation. A central element of this optimisation was the new 40.10 conveyor connection. The contribution deals with the design, assembly and commissioning of the 40.10 belt conveyor which is one of the largest conveyors in deep coal mines with an installed power of 6.000 kW. (Orig.)

Draft Genome Sequence Analysis of a Pseudomonas putida W15Oct28 Strain with Antagonistic Activity to Gram-Positive and Pseudomonas sp. Pathogens

Pseudomonas putida is a member of the fluorescent pseudomonads known to produce the yellow-green fluorescent pyoverdine siderophore. P. putida W15Oct28, isolated from a stream in Brussels, was found to produce compound(s) with antimicrobial activity against the opportunistic pathogens Staphylococcus aureus, Pseudomonas aeruginosa, and the plant pathogen Pseudomonas syringae, an unusual characteristic for P. putida. The active compound production only occurred in media with low iron content and without organic nitrogen sources. Transposon mutants which lost their antimicrobial activity had the majority of insertions in genes involved in the biosynthesis of pyoverdine, although purified pyoverdine was not responsible for the antagonism. Separation of compounds present in culture supernatants revealed the presence of two fractions containing highly hydrophobic molecules active against P. aeruginosa. Analysis of the draft genome confirmed the presence of putisolvin biosynthesis genes and the corresponding lipopeptides were found to contribute to the antimicrobial activity. One cluster of ten genes was detected, comprising a NAD-dependent epimerase, an acetylornithine aminotransferase, an acyl CoA dehydrogenase, a short chain dehydrogenase, a fatty acid desaturase and three genes for a RND efflux pump. P. putida W15Oct28 genome also contains 56 genes encoding TonB-dependent receptors, conferring a high capacity to utilize pyoverdines from other pseudomonads. One unique feature of W15Oct28 is also the presence of different secretion systems including a full set of genes for type IV secretion, and several genes for type VI secretion and their VgrG effectors.

Transformation of topologically close-packed β-W to body-centered cubic α-W: Comparison of experiments and computations.

The enthalpy and activation energy for the transformation of the metastable form of tungsten, β-W, which has the topologically close-packed A15 structure (space group Pm3¯n), to equilibrium α-W, which is body-centered cubic (A2, space group Im3¯m), was measured using differential scanning calorimetry. The β-W films were 1 μm-thick and were prepared by sputter deposition in argon with a small amount of nitrogen. The transformation enthalpy was measured as -8.3 ± 0.4 kJ/mol (-86 ± 4 meV/atom) and the transformation activation energy as 2.2 ± 0.1 eV. The measured enthalpy was found to agree well with the difference in energies of α and β tungsten computed using density functional theory, which gave a value of -82 meV/atom for the transformation enthalpy. A calculated concerted transformation mechanism with a barrier of 0.4 eV/atom, in which all the atoms in an A15 unit cell transform into A2, was found to be inconsistent with the experimentally measured activation energy for any critical nucleus larger than two A2 unit cells. Larger calculations of eight A15 unit cells spontaneously relax to a mechanism in which part of the supercell first transforms from A15 to A2, creating a phase boundary, before the remaining A15 transforms into the A2 phase. Both calculations indicate that a nucleation and growth mechanism is favored over a concerted transformation. More consistent with the experimental activation energy was that of a calculated local transformation mechanism at the A15-A2 phase boundary, computed as 1.7 eV using molecular dynamics simulations. This calculated phase transformation mechanism involves collective rearrangements of W atoms in the disordered interface separating the A15 and A2 phases.

Coincident resection at both ends of random, γ-induced double-strand breaks requires MRX (MRN, Sae2 (Ctp1, and Mre11-nuclease.

Directory of Open Access Journals (Sweden)

Full Text Available Resection is an early step in homology-directed recombinational repair (HDRR of DNA double-strand breaks (DSBs. Resection enables strand invasion as well as reannealing following DNA synthesis across a DSB to assure efficient HDRR. While resection of only one end could result in genome instability, it has not been feasible to address events at both ends of a DSB, or to distinguish 1- versus 2-end resections at random, radiation-induced "dirty" DSBs or even enzyme-induced "clean" DSBs. Previously, we quantitatively addressed resection and the role of Mre11/Rad50/Xrs2 complex (MRX at random DSBs in circular chromosomes within budding yeast based on reduced pulsed-field gel electrophoretic mobility ("PFGE-shift". Here, we extend PFGE analysis to a second dimension and demonstrate unique patterns associated with 0-, 1-, and 2-end resections at DSBs, providing opportunities to examine coincidence of resection. In G2-arrested WT, Δrad51 and Δrad52 cells deficient in late stages of HDRR, resection occurs at both ends of γ-DSBs. However, for radiation-induced and I-SceI-induced DSBs, 1-end resections predominate in MRX (MRN null mutants with or without Ku70. Surprisingly, Sae2 (Ctp1/CtIP and Mre11 nuclease-deficient mutants have similar responses, although there is less impact on repair. Thus, we provide direct molecular characterization of coincident resection at random, radiation-induced DSBs and show that rapid and coincident initiation of resection at γ-DSBs requires MRX, Sae2 protein, and Mre11 nuclease. Structural features of MRX complex are consistent with coincident resection being due to an ability to interact with both DSB ends to directly coordinate resection. Interestingly, coincident resection at clean I-SceI-induced breaks is much less dependent on Mre11 nuclease or Sae2, contrary to a strong dependence on MRX complex, suggesting different roles for these functions at "dirty" and clean DSB ends. These approaches apply to resection at

The impact of W/Mo molar ratio (in the range 0.01 mM : 1 mM and vice-versa), initial pH (1.5 to 4.0) and cathode material (stainless steel mesh (SSM), carbon rod (CR) and titanium sheet (TS)) on the BES performance was systematically investigated. The concentration of Mo(VI) was more influential than W(VI) in determining the rate of deposition of both metals and the rate of hydrogen production. Complete metal recovery was achieved at equimolar W/Mo ratio of 0.05 mM : 0.05 mM. The rates of metal deposition and hydrogen production increased at acidic pH, with the fastest rates at pH 1.5. The morphology of the metal deposits and the valence of the Mo were correlated with W/Mo ratio and pH. CR cathodes (2#) coupled with SSM cathodes (1#) achieved a significant rate of hydrogen production (0.82 ± 0.04 m 3 /m 3 /d) with W and Mo deposition (0.049 ± 0.003 mmol/L/h and 0.140 ± 0.004 mmol/L/h (1#); 0.025 ± 0.001 mmol/L/h and 0.090 ± 0.006 mmol/L/h (2#)).

Full Text Available The aim of this research was to determine the proportion of oil, surfactant and water which could produce a stable O/W microemulsion using combination of three nonionic surfactants with low, high and medium HLB values; and to determine the role of surfactant with a medium HLB value in O/W microemulsion formulation. The first group of microemulsions were prepared using combination of Tween 80, Span 80 and Span 40 (80 %:10 %:10 % with dif- ferent proportions of VCO:surfactant (1:3, 1:3.5 dan 1:4.  The second goups of microemulsion were prepared using combination of Tween 80, Span 80 and Span 40 (90 %:5 %:5 % with different proportions of VCO:surfactant 1:4,1:4.5 dan 1:5.  The stability of microemulsion was determined during storage at room temperature and after being ovened at 105 0C 5 hours and centrifuged at 2300 g 15 minutes. Microemulsion stability was determined by measur- ing absorbance of the microemulsion at 502 nm and then converted to turbidity (%.  In order to determine the role of surfactant with a medium HLB value in the formulation of O/W microemulsion, one set microemulsions were made without surfactant with a medium HLB value, and another set of microemulsions were prepared with different ratios of low and medium HLB surfactant (1:1, 2:1 and 1:2. The most stable microemulsion was achieved when the proportion of VCO:surfactant:water was 4:20:76 and combination of Tween 80:Span 80:Span 40 with the ratio of 90:3.33:6.67. A more stable O/W microemulsion could be obtained when surfactant with a medium HLB value was added to O/W microemulsion formulation. Surfactant with a medium HLB value would link the oil phase and water phase with sur- factant layer, interaction of surfactant-oil and surfactant-water increased. It provided a smooth transition between oil phase and water phase, and the microemulsion became more stable.

The main difference between the three steels which are tested at temperature range from 650 0 C to 750 0 C is due to the hardening elements pf the matrix and the Boron content: 1. 12R72HV (X10NiCrMoTiB 1515) 2% Mn 1,5% Mo 80 ppmB 2. Vaccutherm (X12CrNiWTi 1613) 3% W 2,5 ppmB 3. RGT 21 (X12CrNiWTi 1613) 3% W 50 ppm B. The investigations of all casts are carried out in two different heat treatments which are suitable for the conditions required for the operation of the reactor. Cond. I: 1150 0 C 30 min, water quenced; 800 0 32 hour, air; 10% cold work. Cond. II: 1150 0 C 30 min, water quenched; 10% cold work. In connection with creep test the condition I irrespective of 3 steels show no remarkable difference. The observation at 750 0 C test temperature and also at condition II above 650 0 C on Boron-free Vaccutherm cast shows an unfavourable behaviour. There is no significant difference in the stress dependence of secondary creep rate and also absolute creep rate. A definite superiority is to be found for 12R72HV when considering the values for time-yield-limit-ratio and ductility compared to the W-steels. The test results shows different fracture behaviour. Transcrystalline fracture is found on cast 12R72HV, whereas RGT 21 and Vaccutherm show transition from transcrystalline to intercrystalline fracture, depending on the rupture time and test temperature. The long term rupture specimens show intercrystalline fracture. (author)

2012-01-01

This thesis presents the first measurement of the W + W - production cross section in proton-proton collisions at √(s)=7 TeV using the complete data set of 4.7 fb -1 collected by the ATLAS detector at the LHC in the year 2011. Three di-leptonic decay channels of the W + W - pairs are used for this analysis: decays into two electrons, two muons, and decays into one electron and one muon. For each channel, a region with a high fraction of W + W - events is selected and contributions from background processes are estimated using Monte Carlo simulations and data-driven techniques. In total, 1524 W + W - candidate events are selected, with an estimated background of 545 ± 52 events. The result of the measurement is: σ(pp → W + W - )=52.6±2.1(stat)±4.5(syst)±2.1(lumi) pb This is compatible with the Standard Model cross-section prediction at next-to-leading order of σ(pp → W + W - )=47.0 +2.0 -1.5 pb.

Rola leptyny w regulacji metabolizmu lipidów i węglowodanów

Directory of Open Access Journals (Sweden)

2011-01-01

Full Text Available Leptyna jest białkiem wydzielanym głównie przez tkankę tłuszczową, a jej stężenie we krwi jest ściśle związane z ilością zapasów energetycznych zgromadzonych w adipocytach. Jako hormon leptyna ma niezwykle szeroki zakres działania. Białko to bezpośrednio lub za pośrednictwem układu współczulnego bierze udział w regulacji metabolizmu energetycznego. Leptyna hamuje biosyntezę triacylogliceroli w wątrobie i tkance tłuszczowej, a także w mięśniach szkieletowych, obniżając tym samym ilość odkładanych w nich lipidów. W adipocytach leptyna zmniejsza ekspresję genów kodujących syntazę kwasów tłuszczowych (FAS i karboksylazę acetylo-CoA (ACC – główne enzymy szlaku biosyntezy kwasów tłuszczowych. Zwiększa z kolei ekspresję genu kodującego lipazę zależną od hormonów (HSL, co stymuluje hydrolizę triacylogliceroli w tkance tłuszczowej. Ponadto leptyna wzmaga utlenianie kwasów tłuszczowych w adipocytach, mięśniach szkieletowych oraz w mięśniu sercowym, wywołując wzrost ekspresji genów kodujących podstawowe dla tego procesu enzymy, palmitoilotransferazę karnitynową 1 (CPT1 i dehydrogenazę acylo-CoA o średniej długości łańcucha (MCAD. Wykazano również, że hormon ten zwiększa wrażliwość tkanek na insulinę i poprawia tolerancję glukozy – pod wpływem leptyny wzrasta transport glukozy do komórek oraz intensywność glikolizy.Wiadomo, że leptyna bierze udział w długoterminowej regulacji pobierania pokarmu, jednak coraz więcej badań wskazuje, że ma ona również wpływ na przemiany substratów energetycznych w tkankach obwodowych. Leptyna może zatem kontrolować homeostaz�� energetyczną organizmu wywołując zmiany metabolizmu lipidów i węglowodanów, przede wszystkim w tkance tłuszczowej i w mięśniach.

The SAE 2016 Range Extenders for Electric Vehicles Symposium was a 2-day technical meeting focused on the role of advanced internal combustion engines (ICEs) and other novel energy converter technologies for extending the range of electric vehicles (EVs). The first-of-its-kind symposium was notable for focusing solely on the range extender (REx) technologies and not the EVs. The technical program featured presentations from international leaders from industry, government, national laboratories, and academia. The opening keynote presentations covered a broad range of topics including consumer behavior, policy implications, regulatory considerations, and REx architectures as enablers for advanced technologies. The technical sessions focused on an array of REx technologies including conventional ICEs, as well as less conventional or emerging technologies such as microturbines, fuel cells, low-temperature combustion engines, and aluminum-air batteries. The symposium included two panel sessions. The trend toward increasing vehicle electrification and the changing role of ICEs and other auxiliary power unit technologies for use as REx’s is leading to new research and design development needs. The symposium captured the interest of the industry and research communities in exploring the opportunities and challenges associated with REx’s for EVs. This report includes key takeaways, summarized below, and draft notes for each presentation and panel discussion.

The D0 experiment collected ∼ 15 pb -1 in run 1A (1992- 1993) and ∼ 89 pb -1 in run 1B (1994-1995) of the Fermilab Tevatron Collider using p anti p collisions at √s = 1.8 TeV. Results from analyses of events with W and Z bosons are presented for the run 1B data samples. From W → eν, μν and Z → ee, μμ decays, the W and Z production cross sections and the W width are determined. Events with W → τν decays are used to determine the ratio of the electroweak gauge coupling constants as a measure of lepton universality. Using W → eν and Z → ee decays, the W boson mass is measured

W,Z0 production at the pp collider

Bunce, G.; Gordon, H.A.; Killian, T.J.

1982-01-01

We have examined some experimental questions relating to the production of W's and Z 0 's at a pp collider. To be specific we have considered a Colliding Beam Accelerator (CBA) with center of energy √s = 800 GeV and luminosity L = 10 33 cm -2 sec -1 (the standard BNL Isabelle (ISA) operating conditions). Most experiments should accumulate 10 sec of beam and therefore will have an integrated luminosity L = 10 40 cm -2 . This corresponds to the production of millions of conventional charged W's per interaction region and gives the potential for high statistics studies of the properties of W's and for experiments searching for higher mass objects. Our focus has been on testing predictions of the standard model. We have concentrated on W production since it is likely the standard Z 0 will be observed in the near future. In most cases the W is detected via its semileptonic decay W → l + nu. The specific topics considered are: W +- production: pp → W +- + X, W +- → e +- + nu, pp → W +- + γ + X, polarization effects in W +- production, and very high luminosity experiments

In order to achieve desired mechanical properties of alloys by manipulating grain boundaries (GBs) via solute decoration, it is of great significance to understand the underlying mechanisms of microstructural evolution and plastic deformation. In this work, nanocrystalline (NC) Cu–W alloyed films with W concentrations spanning from 0 to 40 at% were prepared by using magnetron sputtering. Thermal stability (within the temperature range of 200 °C–600 °C) and hardness of the films were investigated by using the x-ray diffraction, transmission electron microscope (TEM) and nanoindentation, respectively. The NC pure Cu film exhibited substantial grain growth upon all annealing temperatures. The Cu–W alloyed films, however, displayed distinct microstructural evolution that depended not only on the W concentration but also on the annealing temperature. At a low temperature of 200 °C, all the Cu–W alloyed films were highly stable, with unconspicuous change in grain sizes. At high temperatures of 400 °C and 600 °C, the microstructural evolution was greatly controlled by the W concentrations. The Cu–W films with low W concentration manifested abnormal grain growth (AGG), while the ones with high W concentrations showed phase separation. TEM observations unveiled that the AGG in the Cu–W alloyed thin films was rationalized by GB migration. Nanoindentation results showed that, although the hardness of both the as-deposited and annealed Cu–W alloyed thin films monotonically increased with W concentrations, a transition from annealing hardening to annealing softening was interestingly observed at the critical W addition of ∼25 at%. It was further revealed that an enhanced GB segregation associated with detwinning was responsible for the annealing hardening, while a reduced solid solution hardening for the annealing softening.

The nucleation process yielding Ir(0) ∼300 nanoparticles from (Bu 4 N) 5 Na 3 [(1,5-COD)Ir·P 2 W 15 Nb 3 O 62 ] (abbreviated hereafter as (COD)Ir·POM 8- , where POM 9- = the polyoxometalate, P 2 W 15 Nb 3 O 62 9- ) under H 2 is investigated to learn the true molecularity, and hence the associated kinetically effective nucleus (KEN), for nanoparticle formation for the first time. Recent work with this prototype transition-metal nanoparticle formation system ( J. Am. Chem. Soc. 2014 , 136 , 17601 - 17615 ) revealed that nucleation in this system is an apparent second-order in the precatalyst, A = (COD)Ir·POM 8- , not the higher order implied by classic nucleation theory and its nA ⇌ A n , "critical nucleus", A n concept. Herein, the three most reasonable more intimate mechanisms of nucleation are tested: bimolecular nucleation, termolecular nucleation, and a mechanism termed "alternative termolecular nucleation" in which 2(COD)Ir + and 1(COD)Ir·POM 8- yield the transition state of the rate-determining step of nucleation. The results obtained definitively rule out a simple bimolecular nucleation mechanism and provide evidence for the alternative termolecular mechanism with a KEN of 3, Ir 3 . All higher molecularity nucleation mechanisms were also ruled out. Further insights into the KEN and its more detailed composition involving hydrogen, {Ir 3 H 2x POM} 6- , are also obtained from the established role of H 2 in the Ir(0) ∼300 formation balanced reaction stoichiometry, from the p(H 2 ) dependence of the kinetics, and from a D 2 /H 2 kinetic isotope effect of 1.2(±0.3). Eight insights and conclusions are presented. A section covering caveats in the current work, and thus needed future studies, is also included.

We present a general argument for the construction of BRST charges of the 'non-critical' W 2,4 , W 2,5 W 2,6 , and W 2,8 strings. This evidences the existence of BRST charges for a kind of soft-type algebras which can be constructed from two copies of quantum W 2,s algebras, (s=3,4,5,6,8). (author). 15 refs

Mosaic tetracycline resistance determinants are a recently discovered class of hybrids of ribosomal protection tet genes. They may show different patterns of mosaicism, but their final size has remained unaltered. Initially thought to be confined to a small group of anaerobic bacteria, mosaic tet genes were then found to be widespread. In the genus Streptococcus, a mosaic tet gene [tet(O/W/32/O)] was first discovered in Streptococcus suis, an emerging drug-resistant pig and human pathogen. In this study, we report the molecular characterization of a tet(O/W/32/O) gene-carrying mobile element from an S. suis isolate. tet(O/W/32/O) was detected, in tandem with tet(40), in a circular 14,741-bp genetic element (39.1% G+C; 17 open reading frames [ORFs] identified). The novel element, which we designated 15K, also carried the macrolide resistance determinant erm(B) and an aminoglycoside resistance four-gene cluster including aadE (streptomycin) and aphA (kanamycin). 15K appeared to be an unstable genetic element that, in the absence of recombinases, is capable of undergoing spontaneous excision under standard growth conditions. In the integrated form, 15K was found inside a 54,879-bp integrative and conjugative element (ICE) (50.5% G+C; 55 ORFs), which we designated ICESsu32457. An ∼1.3-kb segment that apparently served as the att site for excision of the unstable 15K element was identified. The novel ICE was transferable at high frequency to recipients from pathogenic Streptococcus species (S. suis, Streptococcus pyogenes, Streptococcus pneumoniae, and Streptococcus agalactiae), suggesting that the multiresistance 15K element can successfully spread within streptococcal populations.

In this study, polycrystalline tungsten (W) and three oxide dispersed strengthened W with 0.1 vol %, 1.0 vol % and 5.0 vol % lanthanum trioxide (La2O3) were irradiated with low-energy (200 eV) and high-flux (5.8 × 1021 or 1.4 × 1022 ions/m2ṡs) He+ ions at elevated temperature. After He+ irradiation at a fluence of 3.0 × 1025/m2, their surface damages were observed by scanning electron microscopy, energy dispersive spectroscopy, scanning electron microscopy-electron backscatter diffraction, and conductive atomic force microscopy. Micron-sized holes were formed on the surface of W alloys after He+ irradiation at 1100 K. Analysis shows that the La2O3 grains doped in W were sputtered preferentially by the high-flux He+ ions when compared with the W grains. For irradiation at 1550 K, W nano-fuzz was formed at the surfaces of both polycrystalline W and La2O3-doped W. The thickness of the fuzz layers formed at the surface of La2O3-doped W is 40% lower than the one of polycrystalline W. The presence of La2O3 could suppress the diffusion and coalescence of He atoms inside W, which plays an important role in the growth of nanostructures fuzz.

In this Letter, we report a 1064 nm continuous wave Nd:YAG planar waveguide laser with an output power of 1544 W based on the structure of the master oscillator power amplification. A fiber laser is used as the master oscillator, and diode laser arrays are used as the pump source of the waveguide laser amplifier. The dimension of the waveguide is 1  mm (T)×10  mm (W)×60  mm (L), and the dual end oblique pumping is adopted with different angles. After a single-pass amplification, the power is scaled from 323 to 1544 W with the pump power of 2480 W, leading to an optical-to-optical efficiency of 49%. At the maximum output, the beam quality M 2 are measured to be 2.8 and 7.0 in the guided direction and the unguided direction, respectively. To the best of our knowledge, this is the highest output power of a Nd:YAG planar waveguide laser to date.

Water-in-oil-in-water (W/O/W) emulsions could be utilized for fat-reduced food formulation and delivery of bioactive nutrients. However, due to thermodynamic instability, it is difficult to prepare stable double emulsions. The purpose of this study was to improve the stability of W/O/W double emulsions containing 2.0 M MgCl 2 by adding porcine gelatin in the inner water phase. The impact of gelatin on the physical stability, microstructure and micro-rheological properties of W/O/W emulsions was investigated. It was found that, when the concentration of porcine gelatin exceeded 4.0 wt%, the stability of emulsions was improved, due to increased viscoelasticity of emulsion droplets. When MgCl 2 concentration increased to 2.0 M, the particle size of emulsions increased, due to the osmotic pressure gradient, and the presence of gelatin further increased the droplet size. Confocal microscopy results showed that the presence of gelatin could improve the stability of W/O/W emulsions against coalescence。. Copyright © 2018. Published by Elsevier Ltd.

A study of W-pair production in e+e- annihilations at Lep2 is presented, based on 877 W+W- candidates corresponding to an integrated luminosity of 57 pb-1 at sqrt(s) = 183 GeV. Assuming that the angular distributions of the W-pair production and decay, as well as their branching fractions, are described by the Standard Model, the W-pair production cross-section is measured to be 15.43 +- 0.61 (stat.) +- 0.26 (syst.) pb. Assuming lepton universality and combining with our results from lower centre-of-mass energies, the W branching fraction to hadrons is determined to be 67.9 +- 1.2 (stat.) +- 0.5 (syst.)%. The number of W-pair candidates and the angular distributions for each final state (qqlnu,qqqq,lnulnu) are used to determine the triple gauge boson couplings. After combining these values with our results from lower centre-of-mass energies we obtain D(kappa_g)=0.11+0.52-0.37, D(g^z_1)=0.01+0.13-0.12 and lambda=-0.10+0.13-0.12, where the errors include both statistical and systematic uncertainties and each co...

Simmons, F.M.

1994-05-01

The septic 2607-W6 which supports the 222-S complex is operating at 200% capacity. The septic tank has been inspected and found to be sound. Test hole excavations of the existing drainfield indicate that it is disposing of the current waste water effluent load as opposed to treating it. The system is over 40 years old and has not been approved by the Washington State Department of Health. Under the existing operating conditions it is subject to imminent failure. No additional tie-ins or increases in personnel are allowed which will increase the flow to the 2607-W6 system

The main purpose of presented work is to obtain W-Cu & W-Y cylindrical bulk nanostructured billets by explosive consolidation technology (ECT) in hot condition, with low porosity near to theoretical densities and improved physical / mechanical properties. Nanocomposites were subjected to densification into cylindrical steel tube containers using hot explosive consolidation (HEC) technology to fabricate high dense cylindrical billets. The first stage : Preliminary explosive densification of the precursor powder blend is carried out at room temperature with a loading intensity up to 10GPa to increase the initial density and to activate the particle surfaces in the blend. The second stage investigation were carried out for the same already predensified billets, but consolidation were conducted in hot conditions, after heating of samples in between 940-11000C, the intensity of loading was equal to 10GPa. Consolidated different type of W-Cu composition containing 10-40% of nanoscale W, during investigation showed that the combination of high temperatures (above 940°C) and two-stage shock wave compression was beneficial to the consolidation of the incompatible pair W-Cu composites, resulting in high densities, good integrity and good electronic properties. The structure and property of the samples obtained, depended on the sizes of tungsten particles. It was established that in comparison with W-Cu composites with coarse tungsten the application of nanoscale W precursors and depending of content of W gives different result. Tungsten is a prime material candidate for the first wall of a future fusion reactor. In this study, the microstructure and microhardness of tungsten-yttrium (W-Y) composites were investigated as a function of Y doping content (0.5÷2 wt. %). It was found that the crystallite sizes and the powder particle sizes were increased as a result of the increase of Y content. Nearly fully dense materials were obtained for W-Y alloys when the Y content was

This thesis presents the first measurement of the W{sup +}W{sup -} production cross section in proton-proton collisions at {radical}(s)=7 TeV using the complete data set of 4.7 fb{sup -1} collected by the ATLAS detector at the LHC in the year 2011. Three di-leptonic decay channels of the W{sup +}W{sup -} pairs are used for this analysis: decays into two electrons, two muons, and decays into one electron and one muon. For each channel, a region with a high fraction of W{sup +}W{sup -} events is selected and contributions from background processes are estimated using Monte Carlo simulations and data-driven techniques. In total, 1524 W{sup +}W{sup -} candidate events are selected, with an estimated background of 545 {+-} 52 events. The result of the measurement is: {sigma}(pp {yields} W{sup +}W{sup -})=52.6{+-}2.1(stat){+-}4.5(syst){+-}2.1(lumi) pb This is compatible with the Standard Model cross-section prediction at next-to-leading order of {sigma}(pp {yields} W{sup +}W{sup -})=47.0{sup +2.0}{sub -1.5} pb.

Four green iguanas scheduled for euthanasia were used to compare the extent of collateral tissue damage associated with CO(2) laser and 4.0 MHz radiosurgery. The iguanas were anaesthetised and a series of three skin and three muscle incisions was made by 4.0 MHz radiosurgery (0.18 mm wire electrode, 25 W, cut mode) and CO(2) laser (0.3 mm ceramic tip, 15 W focused beam super-pulse mode), and three incisions were made with a scalpel blade as controls. Following euthanasia, a total of 60 skin and 36 muscle sections were evaluated histologically. Radiosurgery and the laser both produced bloodless incisions, but radiosurgery caused significantly less collateral tissue damage in the skin (307 [97] v 386 [108] microm) and the muscle (18 [7] v 91 [15] microm).

Full Text Available The resistance to localised corrosion of the full austenitic 15%Cr-15%Ni-1.2%Mo titanium stabilized stainless steel (DIN W. Nr. 1.4970 was investigated by electrochemical methods including electrochemical impedance spectroscopy (EIS, potentiodynamic polarization and potentiostatic polarization measurements in a phosphate-buffered solution (PBS. The low carbon and non-stabilized austenitic stainless steel, AISI 316L (ASTM F-138, widely used for surgical implants, was also tested for comparison. The tests were conducted at room temperature after a stable potential had been reached. After the electrochemical measurements, the surfaces of the specimens were observed using SEM to evaluate the presence of pits. Potentiodynamic polarization results showed that both steels are prone to localized corrosion. Larger pits were found on the surface of AISI 316L specimens after the electrochemical tests. EIS response has indicated the duplex structure of the passive oxides. The results showed that the electrochemical behaviour of the DIN W. Nr. 1.4970 is better than of AISI 316L steel. Therefore, their application as an implant material may be considered.

We present measurements of triple gauge boson coupling parameters using data recorded by the OPAL detector at LEP2 at a centre-of-mass energy of 172 GeV. A total of 120 W-pair candidates has been selected in the q q(bar) q q(bar), q q(bar) l nu(bar)_l, and l nu(bar)_l l(bar)' nu_l' decay channels, for an integrated luminosity of 10.4 pb^-1. We use these data to determine several different anomalous coupling parameters using the measured cross-section and the distributions of kinematic variables. We measure alpha_B-phi = 0.35 + 1.29 - 1.07 +/- 0.38, alpha_W-phi = 0.00 + 0.30 - 0.28 +/- 0.11, alpha_W = 0.18 + 0.49 - 0.47 +/- 0.23, Delta(g_1^z) = -0.03 + 0.40 -0.37 +/- 0.14, Delta(kappa_gamma^(HISZ)) = 0.03 + 0.55 - 0.51 +/- 0.20, and Delta(kappa) = 0.03 + 0.49 - 0.46 +/- 0.21. Combining the alpha_W-phi result with our previous result obtained from the 161 GeV data sample we measure alpha_W-phi = -0.08 + 0.28 - 0.25 +/- 0.10. All of these measurements are consistent with the Standard Model.

Electron microscopy and diffraction of ordering in Ni-W alloys

International Nuclear Information System (INIS)

Mishra, N.S.

1995-01-01

Electron microscopy and diffraction studies of ordering in stoichiometric Ni-20%W and off-stoichiometric Ni-15%W alloys have been carried out. The specimens of Ni-20%W were first 1,398 K for 4 h and then quenched rapidly into water. Short range order (SRO) spots were observed at {1 1/2 0}* positions. Two hitherto unknown metastable phases: D 2h 25 -Ni 2 W and D0 22 -Ni 3 W were observed in the diffraction patterns. Long range order (LRO) transformations were studied at 1,103 and 1,213 K. Kinetics and mechanism of transformations have been identified. Ni-15%W specimens were solution treated at 1,523 K for 1 h followed by quenching in water. SRO spots similar to those found in Ni-20%W were observed in this alloy as well. The transition to LRO was studied at 1,093 K. Distinct Ni 4 W precipitates could be observed after 5 h of annealing at this temperature. After 100 h of annealing precipitates were found to grow into faceted shape coherent with the disordered matrix. After prolonged annealing for over 150 h the Ni 4 W precipitates began to lose coherency by the generation of misfit dislocations. The microstructural observations have been compared for the stoichiometric and off-stoichiometric alloys

On-Track Testing as a Validation Method of Computational Fluid Dynamic Simulations of a Formula SAE Vehicle

Science.gov (United States)

Weingart, Robert

This thesis is about the validation of a computational fluid dynamics simulation of a ground vehicle by means of a low-budget coast-down test. The vehicle is built to the standards of the 2014 Formula SAE rules. It is equipped with large wings in the front and rear of the car; the vertical loads on the tires are measured by specifically calibrated shock potentiometers. The coast-down test was performed on a runway of a local airport and is used to determine vehicle specific coefficients such as drag, downforce, aerodynamic balance, and rolling resistance for different aerodynamic setups. The test results are then compared to the respective simulated results. The drag deviates about 5% from the simulated to the measured results. The downforce numbers show a deviation up to 18% respectively. Moreover, a sensitivity analysis of inlet velocities, ride heights, and pitch angles was performed with the help of the computational simulation.

10 kW Contactless Power Transfer System for Rapid Charger of Electric Vehicle

OpenAIRE

Yamanaka, Tomohiro; Kaneko, Yasuyoshi; Abe, Shigeru; Yasuda, Tomio

2012-01-01

A contactless power transfer system for charging electric vehicles requires a high efficiency, a large air gap, and a good tolerance to lateral misalignment and needs to be compact and lightweight. A double-sided winding 10 kW transformer based on a 1.5 kW H-shaped core transformer was developed for a rapid charger. Even though the transformer capacity was increased, the dimensions of the 10 kW transformer were almost the same as those of the 1.5 kW transformer. In this paper, the design conc...

Full Text Available W latach 2007-2008 w Bibliotece Uniwersyteckiej w Poznaniu przeprowadzono badania mające określić stan zachowania przechowywanych w jej magazynach gazet i czasopism wielkopolskich z lat 1800-1939 pod kątem ich zakwaszenia. W tym celu zastosowano metodę stanfordzką, połączoną z badaniem pH papieru. Wytypowana do analiz kolekcja obejmowała 7014 woluminów, z których wyodrębniono 384 egzemplarze stanowiące próbę reprezentatywną. W wyniku badań ustalono, że 40% kolekcji jest w bardzo złym stanie, a dalsze 45% to egzemplarze zniszczone i wymagające naprawy. Wszystkie przebadane obiekty wydrukowane zostały na kwaśnym papierze, co więcej – dla 96% kolekcji odnotowano pH poniżej 5. W świetle przeprowadzonych badań należy stwierdzić, że 85% kolekcji powinna zostać przeniesiona na nośniki analogowe i cyfrowe, a następnie, o ile pozwoli na to ich obecny stan zachowania, poddana procesowi odkwaszania.

The measurement of the W boson mass from CDF

International Nuclear Information System (INIS)

1994-06-01

Recent results from LEP experiments have substantially improved the knowledge of the Z boson. However, hadron colliders remain the only source of direct measurements of the W boson. There have been measurements of the W boson mass from the UA2 and CDF collaborations. The W mass continues to be a subject of great interest in testing the Standard Model. Here, the authors have made a preliminary determination of the W boson mass M W = 80.38 ± 0.23 GeV/c 2 from a combined analysis of W → eν and W → μν in anti pp collisions at √s = 1.8 TeV. The electron data alone yields M W = 80.47 ± 0.15(stat.) ± 0.25(syst.) GeV/c 2 , while the muon data gives M W = 80.29 ± 0.20(stat.) ± 0.24(syst.) GeV/c 2

A measurement of W^+W^- production in pp collisions at sqrt(s) = 7 TeV and a search for the Higgs boson are reported. The W^+W^- candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 inverse picobarns. The pp to W^+W^- cross section is measured to be 41.1 ± 15.3 (stat) ± 5.8 (syst) ± 4.5 (lumi) pb, consistent with the standard model prediction. Limits on WW gamma and WWZ anomalous triple gauge couplings are set. The search for the standard model Higgs boson in the W^+W^- decay mode does not reveal any evidence of excess above backgrounds. Limits are set on the production of the Higgs boson in the context of the standard model and in the presence of a sequential fourth family of fermions with high masses. In the latter context, a Higgs boson with mass between 144 and 207 GeV/c2 is ruled out at 95% confidence level.

The transmission lines and launching systems for non ohmic plasma production and heating by ECR-waves at 28 GHz (200 kW, 40 ms) and 70 GHz (200 kW, 100 ms) in the Garching Wendelstein Stellarator W VIIa and at 70 GHz (800 kW, cw) in the future Advanced Stellarator W VII-AS are described. The ECRH systems meet the requirements for neutral gas breakdown (R-wave), heating of a cold plasma (X-mode) and heating of a warm plasma (0-mode) in a combined way. Periodically modulated wall mode converters (sinusoidal m=0 radius modulation, a 0 =31.75 mm at 28 GHz, a 0 =13.9 mm at 70 GHz) convert the circular electric TE/sub on/ gyrotron output mode mixture (mainly TE 02 mode) into a pure TE 01 wave which is used for the long distance transmission in smooth overmoded waveguides (I.D. = 63.5 mm). At the converter inputs the phases between the TE/sub on/ modes are matched by phase shifters. The measured conversion efficiency for characteristic mode mixtures (TE 02 /TE 01 /TE 03 ) at 28 GHz is about 98 %. For the geometrical and electrical matching of different waveguide diameters waveguide tapers with approximate Tschebycheff mode-conversion responses are used

Cold HI gas appears as self-absorption dips in the 21-cm line profiles in and around the giant molecular cloud near W3 and W4. The cold HI cloud is approximately 150 pc long and extends along the galactic plane. It consists of several fragments, each of which is typically approximately 25 pc in diameter and (1 - 4) X 10 4 solar masses. The [H 2 ]/[HI] ratio is estimated to be 15 - 50. The mass of the entire HI cloud amounts to approximately 10 5 solar masses which is comparable to that observed in CO emission. (Auth.)

To assess the value of gray-scale stimulated acoustic emission in differential diagnosis between hepatocellular carcinoma and metastatic adenocarcinoma.Twenty-four cases of hepatocellular carcinoma (HCC) in 23 patients and 26 cases of metastatic adenocarcinoma in 14 patients were prospectively examined using the pluse-inversion harmonic technique after intravenous SH U 508A administration. Gray-scale stimulated acoustic emission (SAE) was measured 5 mins after bolus injection of a contrast agent (4g, 400 mg/ml). The presence or absence of SAE signas at internal and marginal areas of the tumor and the appearance (smooth or irregular) of its border were compared. In addition, the SAE index (SAE (parenchyma) - SAE (tumor)/ SAE (parenchyma)) was histographycally determined using a computerized program (PiView{sup TM}; Mediface, Seoul, Korea). The statistics were analysed using student's test. Of the 24 HCC cases, 20 (83%) showed internal SAE signals, while 23 (96%) marginal signals were emitted. Of the 26 cases of metaststic adenocarcinoma, one (4%) showed internal SAE signals, while in five 23 metastatic lesions (88%). For HCC and metastatic tumors, the mean SAE index was 0.38{+-}0.15 and 0.60{+-}0.08, respectively ({rho}< 0.001). Gray-scale stimulated acoustic emission can be a useful tool in differential diagnosis between hepatocellular carcinoma and metastatic adenocarcinoma.

1993-01-01

The aim of this study was to estimate malabsorption status in humans using a 15 N stable isotope tracer technique. [ 15 N]-glycine, 98.98 atom %, was synthesized in our institute and was administered orally as a single bolus dose to twelve patients. Six of the 12 subjects studied were healthy and 6 were suspected of having malabsorption. Blood, urine and faecal samples were obtained, proteins in the samples were precipitated with sulphosalicylic acid (5%), the eluate was purified with Dowex 50W-X8 (40mm x 2mm column), and derivatised to form the trifluoroacetyl-butyl esters using standard techniques. Gas chromatographic separation was performed on a glass column 2m X 3mm i.d. packed with EGA 1% on Chromosorb W AW 80-100 mesh. An isotope dilution GC/MS method and Kjeldahl digestion followed by MS analysis of nitrogen gas was performed. 15 N isotopomer was used as internal standard. [ 15 N]-Gly elimination in faeces was compared with total 15 N elimination in faeces to distinguish artefacts caused by intestinal bacteria. Significant differences in the amount of [ 15 N]-Gly eliminated in urine and faeces between malabsorption and control patients were obtained. It was concluded that more emphasis should be given to the faeces data than to urine because 15 N elimination in urine is competitive with 15 N incorporation into protein. 12 refs, 4 figs, 4 tabs

Mass determination of moment magnitudes M w and establishing the relationship between M w and M L for moderate and small Kamchatka earthquakes

The average relationship is established between the basic magnitude for the Kamchatka regional catalog, M L , and modern moment magnitude M w. The latter is firmly tied to the value of the source seismic moment M 0 which has a direct physical meaning. M L magnitude is not self-reliant but is obtained through the conversion of the traditional Fedotov's S-wave energy class, K S1,2 F68 . Installation of the digital seismographic network in Kamchatka in 2006-2010 permitted mass estimates of M 0 and M w to be obtained from the regional data. In this paper we outline a number of techniques to estimate M 0 for the Kamchatka earthquakes using the waveforms of regional stations, and then compare the obtained M w estimates with each other and with M L , based on several hundred earthquakes that took place in 2010-2014. On the average, for M w = 3.0-6.0, M w = M L -0.40; this relationship allows obtaining M w estimates (proxy- M w) for a large part of the regional earthquake catalog with M L = 3.4-6.4 ( M w = 3.0-6.0).

(Ti{sub 1-x}W{sub x})C solid solutions (x = 0.05, 0.15, 0.25, 0.35) were synthesized by carbothermal reduction and then were used as hard phases to prepare (Ti,W)C-Ni{sub 3}Al cermets by vacuum sintering. (Ti,W)C-Ni{sub 3}Al cermets showed weak core-rim structure carbide particles embedded in Ni{sub 3}Al binder. As W content in (Ti,W)C increased, core-rim structure of carbide particles got weaker and the contrast of particles lowered down in SEM-BSE morphologies. Furthermore, the densification of cermets was promoted with W content in solid solution increasing, meanwhile TRS and toughness of cermets were improved obviously. In this paper, the wettability of molten metal on different group transition metal carbides was discussed in detail based on valence-electron configurations (VECs) of carbides. - Highlights: • (Ti{sub 1-x}W{sub x})C solid solutions were synthesized by carbothermal reduction. • (Ti,W)C-Ni{sub 3}Al cermets were prepared through powder metallurgy route. • The increase of W can improve wetting and densification significantly. • (Ti,W)C-Ni{sub 3}Al cermets showed a weak core-rim structure particles embedded in binder. • Wetting behavior were discussed from valence-electron configurations of carbides.

Silveira Da

2014-04-01

Full Text Available We report the results on the search for exclusive production of W pairs in the LHC with data collected by the Compact Muon Solenoid detector in proton-proton collisions at √s = 7 TeV. The analysis comprises the two-photon production of a W pairs, pp → pW+ W− p → p νe± νµ∓ p. Two events are observed in data for pT(ℓ > 4 GeV, |η(ℓ| 20 GeV, in agreement with the standard model prediction of 2.2 ± 0.4 signal events with 0.84 ± 0.15 background events. Moreover, a study of the tail of the lepton pair transverse momentum distribution is performed to search for an evidence of anomalous quartic gauge couplings in the γγ → W+ W− vertex. As no events are observed in data, it results in a model-independent upper limits for the anomalous W quartic gauge couplings aW0,C/Λ2, which are of the order of 10−4.

Purpose: Concurrent cisplatin-based chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical cancer. RTOG 0417 was a Phase II study exploring the safety and efficacy of the addition of bevacizumab to standard CRT. Methods and Materials: Eligible patients with bulky tumors (Stage IB-IIIB) were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiotherapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for three cycles. Treatment-related serious adverse event (SAE) and other adverse event (AE) rates within the first 90 days from treatment start were determined. Treatment-related SAEs were defined as any Grade {>=}4 vaginal bleeding or thrombotic event or Grade {>=}3 arterial event, gastrointestinal (GI) bleeding, or bowel/bladder perforation, or any Grade 5 treatment-related death. Treatment-related AEs included all SAEs and Grade 3 or 4 GI toxicity persisting for >2 weeks despite medical intervention, Grade 4 neutropenia or leukopenia persisting for >7 days, febrile neutropenia, Grade 3 or 4 other hematologic toxicity, and Grade 3 or 4 GI, renal, cardiac, pulmonary, hepatic, or neurologic AEs. All AEs were scored using the National Cancer Institute Common Terminology Criteria (CTCAE) v 3.0 (MedDRA version 6.0). Results: A total of 60 patients from 28 institutions were enrolled between 2006 and 2009, and of these, 49 patients were evaluable. The median follow-up was 12.4 months (range, 4.6-31.4 months).The median age was 45 years (range, 22-80 years). Most patients had FIGO Stage IIB (63%) and were of Zubrod performance status of 0 (67%). 80% of cases were squamous. There were no treatment-related SAEs. There were 15 (31%) protocol-specified treatment-related AEs within 90 days of treatment start; the most common were hematologic (12/15; 80%). 18 (37%) occurred during treatment or follow-up at any time. 37 of the 49 patients (76%) had cisplatin and bevacizumab

Full Text Available Ludzki mózg to struktura wykazująca ogromną zmienność w ciągu życia osobniczego. W pierwszym okresie zmiany budowy i czynności spowodowane są procesami rozwoju i dojrzewania. Następnie, dzięki niezwykłej plastyczności synaptycznej, poszczególne ośrodki mózgu przystosowują się do wymagań środowiska, w jakim człowiek funkcjonuje, i do stylu jego życia. Po 40. roku życia włącza się proces zaprogramowanej śmierci neuronów, czyli apoptozy, a w stanie choroby neurony mogą ginąć w procesie nekrozy lub aponekrozy. Neurogeneza na bazie miejscowych albo transplantowanych komórek macierzystych mózgu pełni funkcję naprawczą w powstałych uszkodzeniach, ale może także mieć związek z chorobami psychicznymi i neurologicznymi. U podstaw neuroprotekcji leżą procesy antyoksydacyjne, przeciwzapalne, antyapoptotyczne i przeciwdziałające destrukcyjnemu działaniu jonów wapnia. Wspierającą funkcję w działaniu neuroprotekcyjnym mogą mieć związki pochodzenia roślinnego, podawane w ramach fitoterapii. W ostatnich latach zwrócono uwagę na neuroprotekcyjne właściwości pentacyklicznych triterpenów i ich pochodnych. W pracy omówiono właściwości neuroprotekcyjne kwasu ursolowego, oleanolowego, maslinowego, asjatowego, betulinowego, bosweliowego oraz saponin triterpenowych pozyskiwanych z roślin Bupleurum i Panax ginseng. Saponiny ginseng dodatkowo nasilają neurogenezę w mózgu. Sugeruje się potencjał stosowania wymienionych związków w terapii wielu chorób neurologicznych i psychicznych – z kilkoma zastrzeżeniami: 1 kierunek działania może zależeć od dawki; 2 związki te mogą różnie działać na neurony różnych rodzajów; 3 mogą istnieć niekorzystne interakcje z innymi lekami stosowanymi równocześnie. Większość doświadczeń z użyciem triterpenów wykonano na zwierzętach bądź w hodowlach komórkowych, zagadnienie wymaga więc dalszych badań na ludziach.

Full Text Available The removal of cutting fluids and lubrication in dry machining operations requires a good knowledge and full control of all the mechanisms that lead to tool damage. In order to optimize dry machining operations, it is necessary to clearly identify the wear patterns, determine the contact conditions and define the relationship between the contact parameters and the operating conditions. The idea is to choose optimal cutting conditions which lead to the best contact conditions limiting the triggering or aggravation of wear phenomena. The purpose of this paper is to determine the impact multilayer coatings and cutting parameters on tool wear and temperature at the tool-chip interface for two types of coated carbides (KC810 and KC910 Commercialized inserts during dry turning operation of carbon steel SAE 1030, in order to determine the ideal parameters and guarantee the best performances of the cutting tools. Cutting temperature, Crater and Flank wear have been systematically recorded in order to determine their influence on tool life time. To ensure the optimum choice of machining conditions; the TAGUCHI method associated to multi-factorial method were applied to plan the experiments. It has been noted that cutting speed was the most influential factor on temperature and wear evolution. We noted also that the KC810 insert was more suitable for machining of SAE 1030 Carbon Steel; where The best life time was registered (T=228 min. The KC810 inserts offer 30 min of additional machining time for the same work conditions.

Aerosol measurements at two AERONET (AErosol RObotic NETwork) sites of the Iberian Peninsula: Madrid (40°.45N, 3.72W) and La Coruña (43°.36N, 8°.42W) have been analyzed for the period 2012-2015 to assess aerosol optical properties (intensive and extensive) throughout the atmospheric column and their radiative forcing (RF) and radiative forcing efficiency (RFeff) estimates at the Bottom and Top Of Atmosphere (BOA and TOA respectively). Specific conditions as dust-free and African dust have been considered for the study. Unprecedented, this work uses the quantification of the African dust aerosol at ground level which allows us to study such AERONET products at different intensity levels of African events: Low (L), High (H) and very high (VH). The statistical difference between dust-free and African dust conditions on the aforementioned parameters, quantified by means of the non-parametric Kolmogorov-Smirnov test, is quite clear in Madrid, however it is not in La Coruña. Scattering Angstrom Exponent (SAE) and Absorption Angstrom Exponent (AAE) were found to be 1.64 ± 0.29 and 1.14 ± 0.23 respectively in Madrid for dust-free conditions because typical aerosol sources are traffic emissions and residential heating, and black carbon is an important compound in this aerosol kind. On the other hand, SAE and AAE were 0.96 ± 0.60 and 1.44 ± 0.51 for African dust conditions in this location. RF (at shortwave radiation) seems to decrease as the African dust contribution at ground level is larger which indicates the cooling effect of African dust aerosol in Madrid. We have also proved the potential of a 2D-cluster analysis based on AAE and SAE to differentiate both situations in Madrid. Conversely, it is suggested that aerosols observed in La Coruña under dust-free conditions might come from different sources. Then, SAE and AAE are not good enough indicators to distinguish between dust-free and African dust conditions. Besides, as La Coruña is at a further distance

A 1603 nm high optical signal-to-noise ratio (OSNR) kHz-linewidth linearly-polarized all-fiber single-frequency master-oscillator power amplifier (MOPA) is demonstrated. To suppress the amplified spontaneous emission from Yb 3+ /Er 3+ ions with the customized filters and optimize the length of the double cladding active fiber, an over 15 W stable single-longitudinal-mode laser is achieved with an OSNR of >70 dB. A measured laser linewidth of 4.5 kHz and a polarization-extinction ratio of >23 dB are obtained at the full output power. This L-band high-power single-frequency MOPA is promising for high-resolution molecular spectroscopy and pumping of Tm 3+ -doped or Tm 3+ /Ho 3+ co-doped laser.

The architecture design of a 2mW 18-bit high speed weight voltage type DAC based on dual weight resistance chain

Qixing, Chen; Qiyu, Luo

2013-03-01

At present, the architecture of a digital-to-analog converter (DAC) in essence is based on the weight current, and the average value of its D/A signal current increases in geometric series according to its digital signal bits increase, which is 2n-1 times of its least weight current. But for a dual weight resistance chain type DAC, by using the weight voltage manner to D/A conversion, the D/A signal current is fixed to chain current Icha; it is only 1/2n-1 order of magnitude of the average signal current value of the weight current type DAC. Its principle is: n pairs dual weight resistances form a resistance chain, which ensures the constancy of the chain current; if digital signals control the total weight resistance from the output point to the zero potential point, that could directly control the total weight voltage of the output point, so that the digital signals directly turn into a sum of the weight voltage signals; thus the following goals are realized: (1) the total current is less than 200 μA (2) the total power consumption is less than 2 mW; (3) an 18-bit conversion can be realized by adopting a multi-grade structure; (4) the chip area is one order of magnitude smaller than the subsection current-steering type DAC; (5) the error depends only on the error of the unit resistance, so it is smaller than the error of the subsection current-steering type DAC; (6) the conversion time is only one action time of switch on or off, so its speed is not lower than the present DAC.

Test Procedure) metro/highway cycles. Five different PAG chemistries were selected by varying the starting alcohol, the oxide monomers (ethylene oxide, propylene oxide, or butylene oxide), capped or uncapped, homopolymer or random copolymer. All formulations contained a proprietary additive package and one which contained additional antiwear and friction modifier additives. Laboratory bench tests (Pin-on-Disk, High Frequency Reciprocating Rig (HFRR), Block-on-Ring, Mini-Traction Machine (MTM) identified formulations having friction, wear, and load carrying characteristics similar to or better than baseline GF-5 SAE 5W-20 oil. Motored valvetrain and motored piston ring friction tests showed nearly 50% friction reduction for some of the PAG formulations compared to GF-5 SAE 5W-20 oil. Motored engine tests showed up to 15% friction benefit over GF-5 SAE 5W-20 oil. It was observed that friction benefits are more related to PAG base oil chemistry than their lower viscosity compared to GF-5 SAE 5W-20 oil. Analysis of wear surfaces from laboratory bench tests and bucket tappets from motored valvetrain tests confirmed the presence of PAG molecules. The adsorption of these polar molecules is believed to be reason for friction reduction. However, the wear surfaces also had thin tribo-film derived from additive components. The tribo-film consisting of phosphates, sulfides, and molybdenum disulfide (when molybdenum additive was present) were observed for both GF-5 SAE 5W-20 and PAG fluids. However, when using PAG fluids, motored valvetrain tests showed high initial wear, which is believed to be due to delay in protective tribo-film formation. After the initial wear, the wear rate of PAG fluids was comparable to GF-5 SAE 5W-20 oil. The PAG oil containing additional antiwear and friction reducing additives showed low initial wear as expected. However, when this oil was evaluated in Sequence IVA test, it showed initially low wear comparable to GF-5 oil but wear accelerated with oil

Full Text Available Przedmiotem artykułu są rozważania na temat specyfiki Europy Środkowej w zakresie kolekcji i muzeów sztuki współczesnej oraz możliwość stworzenia alternatywy regionalnej dla krajów zachodnich. Kontekstem dla tych rozważań jest ekspansjonistyczna polityka współczesnych muzeów, która w związku z licznymi nowymi inwestycjami – w szczególności Luwru, Fundacji Guggenheima, Ermitażu – budzi w świecie muzeologicznym różnorakie dylematy. Autorka omawia światowe "marki muzealne" inwestujące w Europie Środkowej, zastanawia się nad skutkami ekspansji tych "koncernów" dla kultury w regionie, wskazuje też na potencjał regionu, który można wykorzystać bez posiłkowania się nazwiskami światowych kolekcjonerów.

modification. Surowy urobek z kopalni rud złota Aghdarreh musi najpierw zostać poddany rozdrobnieniu, aby zapewnić efektywniejsze uwalnianie cząsteczek złota. W chwili obecnej obiegi rozdrabniania obejmują kruszenie jednostopniowe z wykorzystaniem kruszarek szczękowych oraz kruszenie jednostopniowe z użyciem kruszarek półautomatycznych w obiegu zamkniętym z hydrocyklonem. Odzysk złota odbywa się przy zastosowaniu procesu ługowania, z zastosowaniem metody cyjankowej w szeregu mieszalników. W pracy tej przeprowadzono optymalizację procesu rozdrabniania rud w zakładach przeróbczych Aghdarreh prowadzonego w celu zmniejszenia rozmiarów uzyskiwanych cząsteczek złota (Ps0) z 70 μm do ok. 40 μm poprzez zapewnienie ciągłości procesu, z wykorzystaniem metod modelowania i symulacji. Na podstawie dwóch zestawów próbek z ciągu technologicznego rozdrabniania, rozkłady wielkości cząstek zostały statystycznie zrównoważone z wykorzystaniem oprogramowania NorBal. Pierwszy i drugi zbiór danych otrzymanych na podstawie dwóch zestawów próbek wykorzystany został do kalibracji i walidacji modeli, przed przystąpieniem do właściwych badań symulacyjnych z użyciem oprogramowania MODSIM. Symulacje komputerowe przeprowadzono w celu oceny wydajności dwóch proponowanych ciągów technologicznych. Pierwszy ciąg obejmuje istniejące kruszarki półautomatyczne i nowo proponowaną kruszarkę kulową pracującą w obiegu zamkniętym z hydrocyklonem. Drugi rozważany ciąg stanowi istniejąca kruszarka półautomatyczna, następnie proponowana kruszarka kulowa pracująca w obiegu zamkniętym z istniejącym hydrocyklonem. We wszystkich symulacjach bazowano na modelach SAGT, CYCL i MILL do symulacji pracy kruszarek półautomatycznych, pakietu hydrocyklonu oraz pojedynczych kruszarek. Modele SAGT i MILL oparte są na modelu zrównoważonej populacji w procesie rozdrabniania. Model CYCL opiera się na empirycznym modelu klasyfikacji Plitta zastosowanym do hydrocyklonów

Thermodynamic analysis and experimental studied are performed for oxygen solutions in Fe-40% Ni-15% Cr melts where Mn, Si, Ti, Al are used as reducing agents. It is revealed that in the alloys studied the affinity of reducing agents to oxygen essentially lower than in liquid iron, nickel and Fe-40% Ni alloy. This is explained by the fact that the oxygen activity in melts noticeably decreases due to a high chromium content whereas the activity of reducing elements increases in a rather less degree. The agreement between analytical and experimental results confirms the validity of the calculation technique [ru

2017-12-01

A high efficiency single-stage Stirling-type coaxial pulse tube cryocooler (SPTC) operating at around 40 K has been designed, built and tested. The double-inlet and the inertance tubes together with the gas reservoir were adopted as the phase shifters. Under the conditions of 2.5 MPa charging pressure and 30 Hz operating frequency, the prototype has achieved a no-load temperature of 23.8 K with 330 W of electric input power at a rejection temperature of 279 K. When the input power increases to 400 W, it can achieve a cooling capacity of 4.7 W/40 K while rejecting heat at 279 K yielding an efficiency of 7.02% relative to Carnot. It achieves a cooling capacity of 5 W/40 K with an input power of 450 W. It takes 10 minutes for the SPTC to cool to its no-load temperature of 40 K from 295 K.

Production of W + W - pairs via γ * γ * → W + W - subprocess with photon transverse momenta

2018-05-01

We discuss production of W + W - pairs in proton-proton collisions induced by two-photon fusion including, for a first time, transverse momenta of incoming photons. The unintegrated inelastic fluxes (related to proton dissociation) of photons are calculated based on modern parametrizations of deep inelastic structure functions in a broad range of their arguments ( x and Q 2). In our approach we can get separate contributions of different W helicities states. Several one- and two-dimensional differential distributions are shown and discussed. The present results are compared to the results of previous calculations within collinear factorization approach. Similar results are found except of some observables such as e.g. transverse momentum of the pair of W + and W -. We find large contributions to the cross section from the region of large photon virtualities. We show decomposition of the total cross section as well as invariant mass distribution into the polarisation states of both W bosons. The role of the longitudinal F L structure function is quantified. Its inclusion leads to a 4-5% decrease of the cross section, almost independent of M WW .

In-situ monitoring of the physical properties of liquids is of great interest in the automotive industry. For example, lubricants are subject to dilution with diesel fuel as a consequence of late-injection processes, which are necessary for regenerating diesel particulate filters. This dilution can be determined by tracking the viscosity and the density of the lubricant. Here we report the test of two in-plane movement based resonators to explore their capability to monitor oil dilution with diesel and biodiesel. One of the resonators is the commercially available millimeter-sized quartz tuning fork, working at 32.7 kHz. The second resonator is a state-of-the-art micron-sized AlN-based rectangular plate, actuated in the first extensional mode in the MHz range. Electrical impedance measurements were carried out to characterize the performance of the structures in various liquid media in a wide range of viscosities. These measurements were completed with the development of low-cost electronic circuits to track the resonance frequency and the quality factor automatically, these two parameters allow to obtain the viscosity of various fluids under investigation, as in the case of dilution of lubricant SAE 15W40 and biodiesel.

A study of W+W- events accomanied by hard photon radiation produced in e+e- collisions at LEP is presented. Events consistent with being two on-shell W bosons and an isolated photon are selected from 681 pb^-1 of data recorded at 180 GeV < sqrt(s) < 209 GeV. For these data , 187 W+W- candidates are selected with photon energies greater than 2.5 GeV. The selected events are used to determine the W+ W- gamma cross section at five values of sqrt(s). The results are consistent with the Standard Model expectation. These data provide constraints on the related O(alpha) systematic uncertainties on the measurement of the W boson mass at LEP. Finally, the data are used to derive 95% C.L. upper limits on possible anomalous contributions to the W+ W- gamma gamma and W+ W- Z0 gamma vertices.

Gomez, Gervasio [Univ. of Maryland, College Park, MD (United States)

This dissertation reports on measurements of inclusive cross sections times branching fractions into electrons for W and Z bosons produced in pp collisions at ps = 1.8 TeV. From an integrated luminosity of 84.5 pb^-1 recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron, the cross sections are measured to be (p$\\bar{p}$ → W +X) ∙ B(W → e )= 2310 ± 10 (stat) ± 50 (syst) ± 100 (lum) pb and (p$\\bar{p}$ → Z +X) ∙ B(Z → ee)= 221 ± 3 (stat) ± 4 (syst) ± 10 (lum) pb. The cross section ratio R is determined to be (p$\\bar{p}$ → W+X) B(W → e )= (p$\\bar{p}$ → Z + X) ∙ B(Z → ee) = 10.43 ± 0.15 (stat) 0.20 (syst) ± 0.10 (NLO), and R is used to determine B(W → ev ) = 0.1044 ± 0.0015 (stat) ± 0.0020 (syst) 0.0017 (theory) ± 0.0010 (NLO), and W = 2.169 ± 0.031 (stat) ± 0.042 (syst) 0.041 (theory) ± 0.022 (NLO) GeV. The latter is used to set a 95% confidence level upper limit on the partial decay width of the W boson into non-standard model final states, $inv\\atop{W}$ , of 0.213 GeV.

A high statistics measurement of the reaction π - p→ωn with ω→π 0 γ has been performed at the 70 GeV Serpukhov accelerator for 15, 20.2, 25, 30 and 40 GeV/c incident pion momentum, using the NICE set-up with its associated 648-channel γ-ray spectrometer. Values of the density matrix elements, differential and integral cross sections are reported. Already at 15 GeV/c, the unnatural parity exchange contribution to ω production in helicity 1 state is negligible. After a maximum around /t/ approximately equal to 0.12 (GeV/c) 2 , the differential cross section decreases exponentially up to /t/ approximately equal to 0.7 (GeV/c) 2 , where a break is seen in its slope.

Physical properties of W gravities and W strings

International Nuclear Information System (INIS)

Das, S.R.; Dhar, A.; Rama, S.K.

1991-01-01

This paper investigates some basic physical properties of W gravities and W strings, using a free field realization. The authors argue that the configuration space of W gravities have global characteristics in addition to the Euler characteristic. The authors identify one such global quantity to be a monopole charge and show how this charge appears in the exponents. The free energy would then involve a θ parameter. Using a BRST procedure the authors find all the physical states of W 3 and W 4 gravities, and show that physical operators are nonsingular composites of the screening charge operators. (The latter are not physical operators for N ≥ 3.) For W strings we show how the W constraints lead to the emergence of a single (and not many) extra dimension coming from the W-gravity sector. By analyzing the resulting dispersion relations the authors find that both the lower and upper critical dimensions are lowered compared to ordinary two-dimensional gravity. The pure W gravity spectrum reveals an intriguing numerological connection with unitary minimal models coupled to ordinary gravity

Effect of Si and Mn additions on ferrite and austenite phase fractions in 25Cr-7Ni-1.5Mo-3W base super duplex stainless steels

The effect of heat treatment and Si and Mn additions on the ferrite and austenite phase fractions of the super duplex stainless steel (SDSS), Fe-25Cr-7Ni-1.5Mo-3W-Si-Mn-0.25N (numbers are all in wt.% unless specified otherwise), was investigated. The thermodynamic calculations of phase equilibria and phase fractions were performed using the Thermo-Calc program. Based on the calculated results, specific compositions of Si and Mn were selected and alloys with these compositions were analysed by Feritscope, X-ray diffractometry and scanning electron microscopy. The calculated phase fractions and experimentally analysed ones were compared and there was a good agreement between calculations and measurements. The optimum heat treatment condition for Fe-25Cr-7Ni-1.5Mo-3W-0.5Si-0.5Mn-0.25N is to hold at 1050 to 1100 C for 2 h in considering the ferrite to austenite ratio of 50:50 and to avoid second phase precipitation such as the σ phase. It was suggested that an excessive addition of more than 0.8Si and 1.0Mn may induce the σ phase precipitation. (orig.)

Application of the laser cutting machine to the area of cutting steel plates of 5 mm thick or more was first enabled in 1990 by the 2 kW oscillator that was introduced in that year. The thick plate cutting industry has a short history. This paper describes the features and performance of the 6 kW laser cutting machine that was announced in April, 1994. The machine uses a newly developed high-speed axial flow type carbon dioxide laser oscillater with the rated output of 6 kW. As the discharge excitation method, the machine adopted the RF (radio frequency) method that causes low contamination in the discharge tube. The 6 kW laser cutting machine has a number of features such as a large cutting area provided by the oscillator contained in the cutting machine, cutting quality stabilized by the optical path length fixing unit, and automatic functions such as automatic setting of the cutting conditions and scheduled operation. The machine can cut mild steel plates of up to 40 mm thick (or up to 16 mm for stainless steel plates) at the cutting speed of 1600 mm/min for a 16 mm thick plate and 2200 mm/min for a 12 mm thick plate, with the good cut sectional surface. 5 figs., 1 tab.

Since 2009, the incidence of meningococcal serogroup W disease has increased rapidly in the UK because of a single strain (the so-called original UK strain) belonging to the hypervirulent sequence type-11 clonal complex (cc11), with a variant outbreak strain (the so-called 2013 strain) emerging in 2013. Subsequently, the Netherlands has had an increase in the incidence of meningococcal serogroup W disease. We assessed the temporal and phylogenetic associations between the serogroup W outbreaks in the Netherlands and England, and the historical serogroup C outbreaks in both countries. For this observational cohort study, we used national surveillance data for meningococcal serogroup W and serogroup C disease in the Netherlands and England for the epidemiological years (July to June) 1992-93 to 2015-16. We also did whole genome sequencing and core genome multilocus sequence typing (1546 loci) on serogroup W disease isolates from both countries for surveillance years 2008-09 to 2015-16. We used Poisson regression to compare the annual relative increase in the incidence of serogroup W and serogroup C between both countries. In the Netherlands, the incidence of meningococcal serogroup W disease increased substantially in 2015-16 compared with 2014-15, with an incidence rate ratio of 5·2 (95% CI 2·0-13·5) and 11% case fatality. In England, the incidence increased substantially in 2012-13 compared with 2011-12, with an incidence rate ratio of 1·8 (1·2-2·8). The relative increase in the Netherlands from 2014-15 to 2015-16 was 418% (95% CI 99-1248), which was significantly higher than the annual relative increase of 79% (61-99) per year in England from 2011-12 to 2014-15 (p=0·03). Cases due to meningococcal serogroup W cc11 (MenW:cc11) emerged in 2012-13 in the Netherlands. Of 29 MenW:cc11 cases found up to 2015-16, 26 (90%) were caused by the 2013 strain. For both the current serogroup W outbreak and the historical serogroup C outbreak, the increase in incidence

Nanochannel tungsten (W) film is a promising candidate as an alternative to bulk W for use in fusion applications. In previous work it has been shown to have good radiation resistance under helium (He) irradiation. To further understand the influence of the irradiation-induced displacement cascade damage on helium retention behaviour in a fusion environment, in this work, nanochannel W film and bulk W were pre-irradiated by 800 keV Kr2+ ions to the fluence of 2.6  ×  1015 ions cm-2 and subsequently irradiated by 40 keV He+ ions to the fluence of 5  ×  1017 ions cm-2. The Kr2+ ion pre-irradiation greatly increases helium retention in the form of small clusters and retards the formation of large clusters. It can effectively inhibit surface helium blistering under high temperature annealing. Compared with bulk W, no cracks were found in the nanochannel W film post-irradiated by He+ ions at high fluence. The release of helium from the nanochannel W film is more than one order of magnitude higher than that of bulk W whether they are irradiated by single He+ ions or sequentially irradiated by Kr2+ and He+ ions. Moreover, swelling of the bulk W is more serious than that of the nanochannel film. Therefore, nanochannel W film has a higher radiation tolerance performance in the synergistic irradiation.

We study gamma-ray supernova remnant (SNR) W49B and its environment using recent radio and infrared data. Spitzer Infrared Spectrograph low resolution data of W49B shows shocked excitation lines of H{sub 2} (0,0) S(0)-S(7) from the SNR-molecular cloud interaction. The H{sub 2} gas is composed of two components with temperatures of ∼260 K and ∼1060 K, respectively. Various spectral lines from atomic and ionic particles are detected toward W49B. We suggest that the ionic phase has an electron density of ∼500 cm{sup –3} and a temperature of ∼10{sup 4} K by the spectral line diagnoses. The mid- and far-infrared data from MSX, Spitzer, and Herschel reveal a 151 ± 20 K hot dust component with a mass of 7.5 ± 6.6 × 10{sup –4} M {sub ☉} and a 45 ± 4 K warm dust component with a mass of 6.4 ± 3.2 M {sub ☉}. The hot dust is likely from materials swept up by the shock of W49B. The warm dust may possibly originate from the evaporation of clouds interacting with W49B. We build the H I absorption spectra of W49B and four nearby H II regions (W49A, G42.90+0.58, G42.43-0.26, and G43.19-0.53) and study the relation between W49B and the surrounding molecular clouds by employing the 2.12 μm infrared and CO data. We therefore obtain a kinematic distance of ∼10 kpc for W49B and suggest that the remnant is likely associated with the CO cloud at about 40 km s{sup –1}.

Full Text Available Stress patterns in loan verb lexemes in the dialect used by the Old Believers living in the Suwałki-Augustów region The aim of the article is to present the stress pattern phenomenon in loan verb lexemes which function in the Russian dialect of the Old Believers from the Suwałki-Augustów Region. In the last decades, the insular dialect, separated from the general Russian language, has been influenced by the Polish language. Such influence is visible, in particular, in the vocabulary, in the form of loan translations and idiomatic expressions. Stress patterns, along with the root vocabulary and the morphological system, still remains one of the indicators of the Russian essence of the dialect. The native vocabulary of the Old Believers’ dialect maintains Russian accentuation patterns. A similar situation is observed in the case of stress patterns in lexemes borrowed from Polish, which undergo a stress accentuation adaptation; that is, they feature a shift in the place of the stress in relation to the source language. In loan verb morphemes, one can notice the pattern of stress which is not fixed and depends upon the morphological form or, sometimes, the paroxitonic stress, which results from the influence of the Polish language.   Akcentuacja zapożyczonych leksemów czasownikowych w gwarze staroobrzędowców mieszkających w regionie suwalsko-augustowskim Celem artykułu jest zaprezentowanie zjawiska akcentuacji w zapożyczonych leksemach czasownikowych, funkcjonujących w rosyjskiej gwarze staroobrzędowców z regionu suwalsko-augustowskiego.

Highlights: • The analysis of loss-of-coolant accident (LOCA) in W7-X facility. • Burst disc is sufficient to prevent pressure inside the plasma vessel exceeding 110 kPa. • Developed model of the cooling system adequately represents the expected phenomena. - Abstract: Fusion is the energy production technology, which could potentially solve problems with growing energy demand of population in the future. Wendelstein 7-X (W7-X) is an experimental facility of stellarator type, which is currently being built at the Max-Planck-Institute for Plasmaphysics located in Greifswald, Germany. W7-X shall demonstrate that in future the energy could be produced in such type of fusion reactors. The safety analysis is required before the operation of the facility could be started. A rupture of 40 mm diameter pipe, which is connected to the divertor unit (module for plasma cooling) to ensure heat removal from the vacuum vessel in case of no-plasma operation mode “baking” is one of the design basis accidents to be investigated. During “baking” mode the vacuum vessel structures and working fluid – water are heated to the temperature 160 °C. This accident was selected for the detailed analysis using integral code ASTEC, which is developed by IRSN (France) and GRS mbH (Germany). This paper presents the integral analysis of W7-X response to a selected accident scenario. The model of the main cooling circuit and “baking” circuit was developed for ASTEC code. There were analysed two cases: (1) rupture of a pipe connected to the upper divertor unit and (2) rupture of a pipe connected to the lower divertor unit. The results of analysis showed that in both cases the water is almost completely released from the units into the plasma vessel. In both cases the pressure in the plasma vessel rapidly increases and in 28 s the set point for burst disc opening is reached preventing further pressurisation.

Ultra-short-period W/B₄C multilayers for x-ray optics-microstructure limits on reflectivity

Energy Technology Data Exchange (ETDEWEB)

Multilayer thin films are used as Bragg reflectors for soft x-rays in the energy range 50eV < E < 1000eV in many x-ray optics applications such as x-ray microscopes and telescopes, reducing optics for extreme ultraviolet (EUV) lithography, and x-ray polarizers and phase retarders. Applications often depend critically on reflectivity, which has not been systematically characterized for multilayer periods below 20Å. For this study, W/B₄C multilayers were fabricated by magnetron sputtering on Si(111), with periods from 48Å to as little as 4.7Å. The x-ray reflectivity measured at λ = 1.54Å and at 45° incidence (289 eV < E < 860 eV) was found to decrease sharply for multilayer periods less than 15-20Å. Examination by high-resolution transmission electron microscopy (HRTEM) showed an expansion of the thickness of the W-rich layers of 30-40% from the nominal values, consistent with intermixture of the two materials during sputter growth, and discontinuous W-rich layers for multilayer periods below about 15Å. The experimental data for the specular reflectivity in the hard and soft x-ray regimes and the diffuse scattering fit well to a model of multilayer roughness. The model is expressed as a power-law dependence of roughness on spatial frequency. Analysis of small-angle scattering in transmission from multilayers grown on freestanding Si₃N₄ membranes confirms the onset of discontinuity at periods between 14Å and 22Å. Spectroscopy studies by x-ray absorption (NEXAFS) and electron energy loss (EELS) at the boron K-edge (188eV) are consistent with changes in the average boron bonding environment, as the multilayer period decreases and the W-rich layers are increasingly thin and dispersed. A discrete W-rich phase is present for periods at least as small as 6.3Å.

Full Text Available Treścią referatu jest problematyka budowlanego procesu inwestycyjnego w pasie drogowym na terenie miast. W aglomeracjach miejskich realizacja zadań związanych z budową, przebudową lub modernizacją ciągów drogowych lub sieci infrastruktury liniowej związana jest z pokonaniem szczególnych utrudnień. Wynika to nie tylko ze specyfiki technologicznej ale również z szeroko pojętej interakcji społecznych. Inwestorzy realizujący zadania w miastach muszą szukać nie tylko innowacyjnych rozwiązań technicznych ale również muszą spełniać, często - „wygórowane” oczekiwania społeczne. W referacie omówione zostaną typowe zagrożenia procesu inwestycyjnego na etapach koncepcji, projektowania, realizacji i eksploatacji - ze szczególnym uwzględnieniem aspektów dotyczących realizacji liniowych robót budowlanych na obszarach objętych warunkami ochrony, wynikającymi z zapisów ustawy o ochronie zabytków[1]. Należy podkreślić, że ochrona ta zgodnie z Art. 4 przedmiotowej Ustawy polega, na podejmowaniu przez organy administracji publicznej działań mających między innymi na celu: zapewnienie warunków prawnych, organizacyjnych i finansowych, umożliwiających trwałe zachowanie zabytków oraz ich zagospodarowanie i utrzymanie. Przekłada się to na obligatoryjny warunek prowadzenia prac konserwatorskich, restauratorskich i oczywiście robót budowlanych za pozwoleniem właściwego konserwatora zabytków i pod jego nadzorem. Realizacja liniowych zadań inwestycyjnych z natury rzeczy odbywa się nie tylko w obszarze wpływu zabytków nieruchomych ale także w bezpośrednim kontakcie z zabytkami archeologicznymi tj. – zabytkami nieruchomymi, będącymi powierzchniową, podziemną lub podwodną pozostałością egzystencji i działalności człowieka, złożoną z nawarstwień kulturowych i znajdujących się w nich wytworów bądź ich śladów.

Zasadniczym celem niniejszego artykułu jest zbadanie, jaką formę prezentacji innych całkowitych dochodów w sprawozdaniu z całkowitych dochodów wybrały polskie spółki giełdowe, jaka jest istotność wyniku całkowitego oraz średnia liczba pozycji ujawnia-nych w ramach innych zysków całkowitych przez badane spółki publiczne (struktura innych zysków całko-witych.

Full Text Available Operaizm powstał w 1960–1961 roku z inicjatywy Raniero Panzieriego jako nurt radykalnej odnowy teoretycznej marksizmu w walce z obiektywizmem i historyzmem oraz równie radykalnej odnowy strategicznej ruchu robotniczego w walce z dominującym w nim reformizmem. Miał mieć za podstawę materialistyczną lekturę Kapitału „z robotniczego punktu widzenia”. Wkrótce okazało się, że jest głęboko podzielony teoretycznie i politycznie. W 1963 roku w środowisku operaistycznym nastąpił rozłam. Większość skupiona wokół Maria Trontiego oddzieliła się, dokonując antymaterialistycznej rewizji marksizmu i stworzyła metafizykę autonomii robotniczej. Ogromna fala walk robotniczych w latach 1969–1980 przyniosła wyraźne rozstrzygnięcia w fundamentalnych kwestiach spornych, które podzieliły operaistów.

1982-01-01

A functional model breadboard converter and a rare-earth-cobalt, permanent magnet motor; as well as an engineering model converter and PM motor suitable for vehicle installations were developed and tested. The converter and motor achieved an 88% peak efficiency, a maximum output of 26 kW at 26,000 rpm, and a continuous rating of 15 kW. The system also generated power to the source during braking, with a demonstrated peak power available at the converter terminals of approximately 26 kW at 88% efficiency. Major conclusions include: (1) the SAE J227a(D) driving cycle efficiency for the converter/motor is 86% to 88% when energy available for recovery at the converter terminals is included; (2) the converter initial cost is approximately five times that of the permanent magnet motor, but can be reduced by means of LSI logic and integrated liquid cooled semiconductor packages; and (3) an electronically commutated motor with a liquid cooled converter will operate reliably without service or maintenance for the life of a passenger vehicle.

Highlights: → Isothermal (gas + liquid) equilibrium (GLE) data at T = 308.15 K and p = 122.60 kPa. → Solubility of SO 2 in pure PEG 400 presented an extreme maximum of 951 mg . L -1 . → Solubility of SO 2 in w 1 = 0.40 PEGW is an extreme minimum of 190 mg . L -1 . - Abstract: Isothermal (gas + liquid) equilibrium (GLE) data at T = 308.15 K and p = 122.60 kPa are reported for the absorption of dilute SO 2 in various aqueous poly-ethylene glycol 400 (PEG) solutions, in which SO 2 partial pressures are in the range of (0.9 to 92) Pa. Measurements are carried out by a saturation method using a glass absorption apparatus, which was controlled at constant temperatures by a thermostatic circulation bath with a Beckmann thermometer. The GLE data were obtained with uncertainties within 0.02 K for temperature, 0.1 kPa for total pressures, 3% for SO 2 concentration in the gas phase, and 0.6% for SO 2 concentration in the liquid phase. The measurements show that the solubility of dilute SO 2 in the system of {PEG (1) + water (2)} increases with increasing PEG concentration in the mass fraction range of w 1 = (0.40 to 1.00), and the solubility of SO 2 in the system of {PEG (1) + water (2)} presents an extreme minimum at the mass fraction of w 1 = 0.40 of 190 mg . L -1 when SO 2 in the gas phase is designed at Φ SO 2 = 5 . 10 -4 . The peculiarity of this work is used to provide important GLE data for the design and operation of the absorption and desorption process in flue gas desulfurization (FGD) with potential industrial application of the solutions containing PEG.

Hassan, A K

In this work, O/W emulsion sets were prepared by using different concentrations of two nonionic surfactants. The two surfactants, tween 80(HLB=15.0) and span 80(HLB=4.3) were used in a fixed proportions equal to 0.55:0.45 respectively. HLB value of the surfactants blends were fixed at 10.185. The surfactants blend concentration is starting from 3% up to 19%. For each O/W emulsion set the conductivity was measured at room temperature (25±2°), 40, 50, 60, 70 and 80°. Applying the simple linear regression least squares method statistical analysis to the temperature-conductivity obtained data determines the effective surfactants blend concentration required for preparing the most stable O/W emulsion. These results were confirmed by applying the physical stability centrifugation testing and the phase inversion temperature range measurements. The results indicated that, the relation which represents the most stable O/W emulsion has the strongest direct linear relationship between temperature and conductivity. This relationship is linear up to 80°. This work proves that, the most stable O/W emulsion is determined via the determination of the maximum R² value by applying of the simple linear regression least squares method to the temperature-conductivity obtained data up to 80°, in addition to, the true maximum slope is represented by the equation which has the maximum R² value. Because the conditions would be changed in a more complex formulation, the method of the determination of the effective surfactants blend concentration was verified by applying it for more complex formulations of 2% O/W miconazole nitrate cream and the results indicate its reproducibility.

To provide transmission data for broad 25-39 kVp (kilovolt peak) W/Rh and 25-49 kVp W/Al (target/filter, W-tungsten, Rh-rhodium, and Al-aluminum) x-ray beams through common shielding materials, such as lead, concrete, gypsum wallboard, wood, steel, and plate glass. The unfiltered W-target x-ray spectra measured on a Selenia Dimensions system (Hologic Inc., Bedford, MA) set at 20-49 kVp were, respectively, filtered using 50-μm Rh and 700-μm Al, and were subsequently used for Monte Carlo calculations. The transmission of broad x-ray beams through shielding materials was simulated using Geant4 low energy electromagnetic physics package with photon- and electron-processes above 250 eV, including photoelectric effect, Compton scattering, and Rayleigh scattering. The calculated transmission data were fitted using Archer equation with a robust fitting algorithm. The transmission of broad x-ray beams through the above-mentioned shielding materials was calculated down to about 10(-5) for 25-39 kVp W/Rh and 25-49 kVp W/Al. The fitted results of α, β, and γ in Archer equation were provided. The α values of kVp ≥ 40 were approximately consistent with those of NCRP Report No. 147. These data provide inputs for the shielding designs of x-ray imaging facilities with W-anode x-ray beams, such as from Selenia Dimensions.

Badania wykonano według centralnego kompozycyjnego planu doświadczenia, przewidującego wykonanie badań dziewięciu mieszanek betonowych o zróżnicowanym składzie. Jako kryteria optymalizacji przyjęto: maksimum wytrzymałości na ściskanie fc po 28, 90 i 180 dniach dojrzewania betonu, maksimum krytycznego współczynnika intensywności naprężeń KIcS i maksimum współczynnika sprężystości podłużnej E po 28 i 180 dniach dojrzewania betonu, minimum objętości porów powietrznych w betonie A oraz minimalny wymiar fraktalny określony metodą cięciwy DC i metodą pudełkową DBC. Objętość porów powietrznych określono na podstawie analizy płaskich przekrojów betonu metodami stereologicznymi. Analizie fraktalnej poddano uzyskane w badaniu odporności na pękanie powierzchnie przełomów betonów. Optymalizację przeprowadzono dla trzech wariantów I, II i III. Uzyskane wyniki potwierdziły występowanie ścisłej zależności między właściwościami a strukturą betonów, w tym betonów z dodatkiem metakaolinitu. Wykazano także, że ze względu na przyjęte kryteria optymalizacji celowe jest projektowanie betonów przy założeniu względnie niskiego stosunku woda/spoiwo oraz względnie dużego udziału dodatku metakaolinitu.

Collisional-radiative model including recombination processes for W27+ ion★

We have constructed a collisional-radiative (CR) model for W27+ ions including 226 configurations with n ≤ 9 and ł ≤ 5 for spectroscopic diagnostics. We newly include recombination processes in the model and this is the first result of extreme ultraviolet spectrum calculated for recombining plasma component. Calculated spectra in 40-70 Å range in ionizing and recombining plasma components show similar 3 strong lines and 1 line weak in recombining plasma component at 45-50 Å and many weak lines at 50-65 Å for both components. Recombination processes do not contribute much to the spectrum at around 60 Å for W27+ ion. Dielectronic satellite lines are also minor contribution to the spectrum of recombining plasma component. Dielectronic recombination (DR) rate coefficient from W28+ to W27+ ions is also calculated with the same atomic data in the CR model. We found that larger set of energy levels including many autoionizing states gave larger DR rate coefficients but our rate agree within factor 6 with other works at electron temperature around 1 keV in which W27+ and W28+ ions are usually observed in plasmas.

Brandhorst, Henry W., Jr.; Chapman, Peter A., Jr.

2008-07-01

The NASA Vision for Exploration of the moon may someday require a nuclear reactor coupled with a free-piston Stirling convertor at a power level of 30-40 kW. In the 1990s, Mechanical Technology Inc.'s Stirling Engine Systems Division (some of whose Stirling personnel are now at Foster-Miller, Inc.) developed a 25 kW free-piston Stirling Space Power Demonstrator Engine under the SP-100 program. This system consisted of two 12.5 kW engines connected at their hot ends and mounted in tandem to cancel vibration. Recently, NASA and DoE have been developing dual 55 and 80 W Stirling convertor systems for potential use with radioisotope heat sources. Total test times of all convertors in this effort exceed 120,000 h. Recently, NASA began a new project with Auburn University to develop a 5 kW, single convertor for potential use in a lunar surface reactor power system. Goals of this development program include a specific power in excess of 140 W/kg at the convertor level, lifetime in excess of five years and a control system that will safely manage the convertors in case of an emergency. Auburn University awarded a subcontract to Foster-Miller, Inc. to undertake development of the 5 kW Stirling convertor assembly. The characteristics of the design along with progress in developing the system will be described.

2016-01-14

In the second run of the LHC, which started in April 2015, an accurate understanding of Standard Model processes is more crucial than ever. Processes including electroweak gauge bosons serve as standard candles for SM measurements, and equally constitute important background for BSM searches. We here present the NLO QCD virtual contributions to W+W- + jet in an analytic format obtained through unitarity methods and show results for the full process using an implementation into the Monte Carlo event generator MCFM. Phenomenologically, we investigate total as well as differential cross sections for the LHC with 14 TeV center-of-mass energy, as well as a future 100 TeV proton-proton machine. In the format presented here, the one-loop virtual contributions also serve as important ingredients in the calculation of W+W- pair production at NNLO.

CP violating observables in e$^{-}$e$^{+}$ --> W$^{-}$W$^{+}$

CERN Document Server

Chang, D; Phillips, I

1993-01-01

We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of CP violation in the process $e^-e^+ \\to W^-W^+$. These asymmetries are sensitive to different linear combinations of the CP violating form factors in the three gauge boson $W^-W^+$ production vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic modes of $W$'s decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct CP--odd observables are also employed. These CP violating observables are illustrated in the generalized Left-Right Model and the Charged Higgs Model.

Measurement of the W boson mass with the ATLAS detector

International Nuclear Information System (INIS)

Kivernyk, Oleh

2016-01-01

This thesis describes a measurement of the W boson mass with the ATLAS detector based on the data-set recorded by ATLAS in 2011 at a centre-of-mass energy of 7 TeV, and corresponding to 4.6 inverse femto-barn of integrated luminosity. Measurements are performed through template fits to the transverse momentum distributions of charged leptons and to transverse mass distributions of the W boson, in electron and muon decay modes in various kinematic categories. The individual measurements are found to be consistent and their combination leads to a value of m W = 80371.1 ± 18.6 MeV. The measured value of the W boson mass is compatible with the current world average of m W = 80385 ± 15 MeV. The uncertainty is competitive with the current most precise measurements performed by the CDF and D0 collaborations. (author) [fr

A study of W/sup +/W/sup -/ events accompanied by hard photon radiation, E/sub gamma />2.5 GeV, produced in e^{+}e^{-} collisions at LEP is presented. Events consistent with being two on- shell W-bosons and an isolated photon are selected from 681 pb/sup -1 / of data recorded at 180 GeV< square root s<209 GeV. From the sample of 187 selected W/sup +/W/sup -/ gamma candidates with photon energies greater than 2.5 GeV, the W/sup +/W/sup -/ gamma cross- section is determined at five values of square root s. The results are consistent with the standard model expectation. Averaging over all energies, the ratio of the observed cross-section to the standard model expectation is R(data/SM)=0.99+or-0.09+or-0.04, where the errors represent the statistical and systematic uncertainties respectively. These data provide constraints on the related O( alpha ) systematic uncertainties on the measurement of the W-boson mass at LEP. Finally, the data are used to derive 95% confidence level upper limits on possible anomalo...

We show that the Zamolodchikov's and Polyakov-Bershadsky nonlinear algebras W 3 and W (2) 3 can be embedded as subalgebras into some linear algebras with finite set of currents. Using these linear algebras we find new field realizations of W (2) 3 and W 3 which could be a starting point for constructing new versions of W-string theories. We also reveal a number of hidden relationships between W 3 and W (2) 3 . We conjecture that similar linear algebras can exist for other W-algebra as well. (author). 10 refs

Highlights: ► Corrosion inhibition of a water-base copolymer, ATP, was studied. ► Efficiency more than 90% was obtained with 0.8 mmol/L ATP in 2000 rpm. ► ATP obeys Langmuir isotherm in static and hydrodynamic conditions. ► With the presence of ATP, OM images showed a decrease in surface attack. - Abstract: The effect of static and hydrodynamic conditions (0–2000 rpm) on corrosion inhibition of a water-base acrylic terpolymer (ATP), methyl methacrylate/butyl acrylate/acrylic acid, for SAE1018 steel in simulated sour petroleum corrosive solution (NACE 1D196) were investigated by AC/DC electrochemical tests. Increase in rotation speed accelerates the corrosion rate; however the corrosion inhibitor efficiency increases. This was attributed to the enhanced mass transport of inhibitor molecules to the metal surface. OM examinations also demonstrate that in presence of ATP, a decrease in corrosion attacks is observed. Thermodynamic calculations also showed that ATP obeys Langmuir adsorption isotherm and adsorbs chemically into the surface.

Cross sections for the reaction π - p→ωn, ω→π 0 γ have been measured with good statistics at incident-pion momenta of 15, 20, 25, 30, and 40 GeV/c. The experiments were performed at the 70-GeV IHEP accelerator, using the NICE 648-channel hodoscopic spectrometer. The density matrix elements and the differential and integrated cross sections for the reaction have been determined. The unnatural-parity exchange contribution to the production of ω mesons in the state with helicity 1 is already insignificant at 15 GeV/c. With increasing Vertical BartVertical Bar the differential cross sections pass through a maximum at Vertical BartVertical Barapprox. =0.12 (GeV/c) 2 and then fall exponentially until Vertical BartVertical Barapprox. =0.7 (GeV/c) 2 ; at that point the curve bends sharply, the cross section falling off much less rapidly for larger values of Vertical BartVertical Bar

Regorafenib (Stivarga) is an oral small-molecule multikinase inhibitor commonly used against a variety of cancers. We performed a meta-analysis of all phase 3 randomized controlled trials (RCTs) of regorafenib to quantify the increased risk of SAEs and FAEs. We carried out a systematic search of electronic databases for studies published from inception to February 2017 without any restrictions. Eligibility criteria included phase 3 RCTs of tumors comparing regorafenib, alone or in combination with non-targeted chemotherapy (regorafenib arm) versus placebo or non-targeted chemotherapy (control arm). Data on SAEs and FAEs were extracted from each study and pooled to determine the overall incidence, relative risks (RRs) and 95% confidence intervals (CIs). A total of four phase 3 RCTs involving 1736 cancer patients met the eligibility criteria and were included. The overall incidence of SAEs and FAEs with regorafenib were 0.23 (95%CI, 0.05-0.40) and 0.02 (95%CI, 0.01-0.03), respectively. Compared with control, the summary RR of developing a regorafenib-related SAE was 1.60 (95%CI, 0.95-2.68, P=0.07), the summary RR of developing a regorafenib-related FAE was 1.71 (95%CI, 0.69-4.24, P=0.25). No evidence was found for the association between regorafenib and higher risk of SAEs and FAEs. This association varied significantly with cancer types (P=0.02) for SAEs but no evidence of heterogeneity was found for FAEs. This meta-analysis demonstrates no evidence for the association between regorafenib and higher risk of SAEs and FAEs. This analysis will be important when considering the trade-off of regorafenib treatment during clinical decision-making.

Ze względu na łatwość przyswajania przez organizm składników mineralnych zawartych w wodach mineralnych konieczne jest świadome wybieranie produktu o składzie dostosowanym do indywidualnych potrzeb. Oprócz makroskładników, których charakterystyka ilościowa zawsze widnieje na etykietach, wody mineralne zawierają również mikroelementy. Celem pracy była analiza koncentracji pierwiastków śladowych w 22 butelkowanych wodach mineralnych dostępnych w handlu na terenie Rzeszowa. Artykuł zawiera główne zagadnienia dotyczące znaczenia wody dla prawidłowego funkcjonowania organizmu oraz wpływu mikroelementów na zdrowie człowieka. W badaniach zastosowano metodę całkowitego odbicia promieniowania rentgenowskiego TXRF. Analizy wykazały obecność 18 pierwiastków śladowych w badanych wodach: Al, As, Ba, Br, Co, Cr, Cu, Fe, Ge, I, Mn, Ni, P, Rb, Se, Sr, Ti, Zn. Najwyższe stężenia mikroskładników w przeważającej większości występują w wodach leczniczych. Żadna z badanych wód mogąca służyć jako stałe źródło płynów w diecie (wody nisko-, średnio- i wysokozmineralizowane nie zawiera mikroskładników w ilości, która pozwalałaby na fizjologiczno-odżywcze oddziaływanie na organizm. Dodatkowo wykazano, że pomiędzy stężeniem bromu i germanu istnieje silna korelacja dodatnia R2 = 0,993.

Highlights: • The emissivity of tungsten coatings deposited on carbon substrates such as CFC and fine grain graphite was measured at the wavelengths of 1.064 μm, 1.75 μm, 3.75 μm and 4.0 μm in the temperature range of 400 °C–1200 °C. • The emissivity of other materials of interest for nuclear fusion such as tungsten and beryllium was measured as well. • The influence of substrate structure and of the viewing angle on the emissivity of W coatings was investigated in detail. - Abstract: Tungsten coatings deposited on carbon materials such as carbon fiber composite (CFC) or fine grain graphite are currently used in fusion devices as amour for plasma facing components (PFC). More than 4000 carbon tiles were W-coated by Combined Magnetron Sputtering and Ion Implantation technology for the ITER-like Wall at JET, ASDEX Upgrade and WEST tokamaks. The emissivity of W coatings is a key parameter required by protection systems of the W-coated PFC and also by the diagnostic tools in order to get correct values of temperature and heat loading. The emissivity of tungsten is rather well known, but the literature data refer to bulk tungsten or tungsten foils and not to coatings deposited on carbon materials. The emissivity was measured at the wavelengths of 1.064 μm, 1.75 μm, 3.75 μm and 4.0 μm. It was found that the structure of the substrate has a significant influence on the emissivity values. The temperature dependence of the emissivity in the range of 400 °C–1200 °C and the influence of the viewing angle were investigated as well. The results are given in a table for W coatings and for other materials of interest for fusion such as bulk W and bulk Be.

The trioxidomonosulfidomolybdate and -tungstate anions [(Mo/W)O{sub 3}S]{sup 2-} are the first products formed when passing H{sub 2}S gas through a solution of the oxidometalates. Their potassium, rubidium and cesium salt hydrates form as crystalline precipitates from these solutions depending on pH, the polarity of the solvent, educt concentrations and temperature. The structures of the sesqui- (K) and mono- (Rb, Cs) hydrates have been determined by means of X-ray single crystal diffraction data. The potassium sesquihydrates K{sub 2}[(Mo/W)O{sub 3}S] . 1.5 H{sub 2}O are isotypic and crystallize with a new structure type (monoclinic, space group C2/c, M = Mo/W: a = 987.0(2)/993.13(11), b = 831.75(14)/831.10(11), c = 1868.9(4)/1865.2(2) pm, {beta} = 99.34(2)/99.153(8) , R1 = 0.0352/0.0390). In the crystal structure the [(Mo/W)O{sub 3}S]{sup 2-} anions are connected via hydrogen bonds to form columns along the c direction. Channels containing only water molecules run along the [101] direction. The dehydration process proceeds in a topotactic reaction between 60 to 95 C and yields crystals of the anhydrous salts K{sub 2}[(Mo/W)O{sub 3}S]. The two different K+ cations exhibit a 5 + 3 and 5 + 2 O/S coordination. The heavier alkali metal cations form the four monohydrates (Rb/Cs){sub 2}[(Mo/W)O{sub 3}S] . H{sub 2}O (trigonal rhombohedral, space group R anti 3m) with lattice parameters for the Rb/Cs molybdates of a = 621.17(6)/624.62(10), c = 3377.9(4)/3388.6(8) pm (R1 = 0.0505/0.0734) and the tungstates of a = 642.80(3)/643.3(4), c = 3532.8(3)/3566(4) pm (R1 = 0.0348/0.0660). In the structures the 3m symmetrical tetrahedra are arranged to form double layers in such a way, that the O{sub 3} bases of the tetrahedra are pointing towards each other in a staggered conformation. These double layers are stacked in the c direction in a rhombohedral sequence. In these hydrates, there are no distinct hydrogen bonds. Instead, partially disordered pairs of H{sub 2}O molecules are

We have measured the $W$ and $Z$ boson production cross-sections in proton-proton collisions at a centre-of-mass energy of 7 TeV, using approximately 16.5 pb$^{-1}$ of data. The $W$ and $Z$ bosons are reconstructed from muons with transverse momentum $p_T$ exceeding 20 GeV, pseudorapidity $\\eta_{\\mu}$ within $2.0 - 4.5$., and, in the case of the \\zed, a dimuon invariant mass $m_{Z}$ in the range 81 $\\leq m_{Z} \\leq$ 101 GeV.

Utility Power Group has achieved a significant reduction in the installed cost of grid-connected PV systems. The two part technical approach focused on 1) The utilization of a large area factory assembled PV panel, and 2) The integration and packaging of all sub-array power conversion and control functions within a single factory produced enclosure. Eight engineering prototype 15kW ac single axis solar tracking sub-arrays were designed, fabricated, and installed at the Sacramento Municipal Utility District's Hedge Substation site in 1996 and are being evaluated for performance and reliability. A number of design enhancements will be implemented in 1997 and demonstrated by the field deployment and operation of over twenty advanced sub-array PV power systems.

Full Text Available W pracy przedstawiono wyniki zastosowania modelu SWMM do obliczenia przepływów o prawdopodobieństwach 50, 10, 2 i 1% w 8. przekrojach Potoku Służewieckiego na odcinku od km 0+000 do 6+576 oraz w 2. przekrojach Rowu Wolica. Zlewnia Potoku Służewieckiego jest zlokalizowana w południowej części Warszawy. Największe zagrożenie powodziowe występuje na odcinku Potoku Służewieckiego od km 0+000 do 3+875. Przepustowość koryta Potoku na tym odcinku kształtuje się na poziomie przepływu maksymalnego o prawdopodobieństwie 50%. Największe wartości przepływów w Potoku Służewieckim prognozowano w przekroju obliczeniowym numer V (km 4+267: Q50% = 13,863, Q10% = 23,019, Q2% = 28,825 i Q1% = 30,500 m3·s-1. Jedną z przyczyn występowania zagrożenia powodziowego w dolnym biegu Potoku Służewieckiego jest dopływ dużej ilości wód opadowych Rowem Wolica. Wartości przepływów w górnym odcinku Rowu Wolica (w przekroju VI zawierały się w granicach od 8,005 do 12,402 m3·s-1, w zależności od prawdopodobieństwa wystąpienia opadu obliczeniowego. W celu określenia możliwości redukcji przepływów w Rowie Wolica, przeprowadzono obliczenia w których uwzględniono zastosowanie kryzy na odcinku ujściowym kolektora do kanału otwartego. Zastosowanie kryzy w kolektorze pozwoli zredukować przepływy o prawdopodobieństwach 50, 10 i 2% odpowiednio o 61,0; 46,0 i 36,6%. Zastosowanie kryzy o stałej średnicy ϕ1,08 m, ustalonej dla przepływu o prawdopodobieństwie 2%, spowoduje znacznie mniejszą redukcję przepływów maksymalnych o prawdopodobieństwach 50 i 10%.

Highlights: • Pure α-phase tungsten nanostructures were deposited by DC-magnetron sputtering. • Non-delaminated coatings were achieved at powers ≤50 W. • The coating thicknesses vary from 30 nm up to ∼4.0 μm. • The influence of the substrate on the coating properties was investigated. • We report on the morphological, microstructural and mechanical properties. - Abstract: Nanostructured tungsten (nanoW) coatings have been deposited by DC magnetron sputtering. First, the influence of the sputtering power on the adhesion of the coatings to the substrate was investigated by depositing coatings at powers varying from 30 up to 220 W. Non-delaminated coatings were achieved at powers ≤50 W. Second, the influence of coating thickness on the morphological, microstructural and mechanical properties was investigated for films deposited at 50 W with thicknesses varying from 30 nm up to ∼4.0 μm. SEM images reveal that all the films are highly compact, consisting of nanometer sized columns that grow perpendicular to the substrate. XRD data evidence that films are monophasic, being made of pure α-phase. All coatings show compressive stress and low micro-strain. Nanoindentation tests show that coatings have a hardness higher than that reported for coarse grained W. No significant dependence of the previous properties on coating thickness was observed. Finally, the influence of the substrate on coatings properties was studied, by depositing a W coating at a power of 50 W on a commercial steel substrate: no significant dependence was found.

The synthesis, characterization and catalytic capability of the NiW-nano-hydroxyapatite (NiW-nHA) composite were investigated in this paper. The NiW-nHA catalyst was prepared by a co-precipitation method. Then Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDX) were used to analyze this material. In addition, the catalytic capacity of the NiW-nHA composite was also examined by FT-IR and gas chromatography (GC). The results of FT-IR analysis indicated that Ni, W and nHA combined closely. TEM observation revealed that this catalyst was needle shaped and the crystal retained a nanometer size. XRD data also suggested that a new phase of CaWO4 appeared and the lattice parameters of nHA changed in this system. nHA was the carrier of metals. The rates of Ni/W-loading were 73.24% and 65.99% according to the EDX data, respectively. Furthermore, the conversion of 91.88% Jatropha oil was achieved at 360 °C and 3 MPa h-1 over NiW-nHA catalyst. The straight chain alkanes ranging from C15 to C18 were the main components in the production. The yield of C15-C18 alkanes was up to 83.56 wt%. The reaction pathway involved hydrocracking of the C&z.dbd;C bonds of these triglycerides from Jatropha oil. This paper developed a novel non-sulfided catalyst to obtain a ``green biofuel'' from vegetable oil.

The thermo-mechanical behaviour of W-Cu metal matrix composites for fusion heat sink applications: The influence of the Cu content

Copper and its alloys are used as heat sink materials for next generation fusion devices and will be joined to tungsten as an armour material. However, the joint of W and Cu experiences high thermal stresses when exposed to high heat loads so an interlayer material could effectively ensure the lifetime of the component by reducing the thermal mismatch. Many researchers have published results on the production of W-Cu composites aiming attention at its thermal conductivity; nevertheless, the mechanical performance of these composites remains poor. This paper reports the characterization of the thermo-mechanical behaviour of W-Cu composites produced via a liquid Cu melt infiltration of porous W preform. This technique was applied to produce composites with 15, 30 and 40 wt% Cu. The microstructure, thermal properties, and mechanical performance were investigated and measured from RT to 800 °C. The results demonstrated that high densification and superior mechanical properties can indeed be achieved via this manufacturing route. The mechanical properties (elastic modulus, fracture toughness, and strength) of the composites show a certain dependency on the Cu content; fracture mode shifts from the dominantly brittle fracture of W particles with constrained deformation of the Cu phase at low Cu content to the predominance of the ductile fracture of Cu when its ratio is higher. Though strong degradation is observed at 800 °C, the mechanical properties at operational temperatures, i.e. below 350 °C, remain rather high-even better than W/Cu materials reported previously. In addition, we demonstrated that the elastic modulus, and therefore the coefficient of thermal expansion, can be tailored via control of the W skeleton's porosity. As a result, the W-Cu composites presented here would successfully drive away heat produced in the fusion chamber avoiding the mismatch between materials while contributing to the structural support of the system.

The production of W+W- pairs is analysed in a data sample collected by ALEPH at a mean centre-of-mass energy of 182.7 GeV, corresponding to an integrated luminosity of 57 pb-1. Cross sections are given for different topologies of W decays into leptons or hadrons. Under Standard Model assumptions for the W-pair production and decay, the W-pair cross section is measured to be 15.57+-0.62(stat.)+-0.29(syst.) pb. Using also the W-pair data samples collected by ALEPH at lower centre-of-mass energies, the decay branching ratio of the W boson into hadrons is measured to be B(W->hadrons)= 68.93+-1.21(stat.)+-0.51(syst.)%, allowing a determination of the CKM matrix element |Vcs|= 1.043 +- 0.058(stat.) +- 0.026(syst.). The agreement of the cross sections with the Standard Model prediction allows a limit to be set on the W decay rate to undetectable final states.

Hydrophilic Surface Modification of PDMS Microchannel for O/W and W/O/W Emulsions

Directory of Open Access Journals (Sweden)

Shazia Bashir

2015-09-01

Full Text Available A surface modification method for bonded polydimethylsiloxane (PDMS microchannels is presented herein. Polymerization of acrylic acid was performed on the surface of a microchannel using an inline atmospheric pressure dielectric barrier microplasma technique. The surface treatment changes the wettability of the microchannel from hydrophobic to hydrophilic. This is a challenging task due to the fast hydrophobic recovery of the PDMS surface after modification. This modification allows the formation of highly monodisperse oil-in-water (O/W droplets. The generation of water-in-oil-in-water (W/O/W double emulsions was successfully achieved by connecting in series a hydrophobic microchip with a modified hydrophilic microchip. An original channel blocking technique to pattern the surface wettability of a specific section of a microchip using a viscous liquid comprising a mixture of honey and glycerol, is also presented for generating W/O/W emulsions on a single chip.

To analyze the costs associated with two surgical procedures for lower urinary tract symptoms secondary to benign prostatic hyperplasia: GreenLight XPS 180¦W versus the gold standard transurethral resection of the prostate. A multicenter, retrospective cost study was carried out from the National Health Service perspective, over a 3-month time period. Costs were broken down into pre-surgical, surgical and post-surgical phases. Data were extracted from records of patients operated sequentially, with IPSS=15, Qmax=15 mL/seg and a prostate volume of 40-80mL, adding only direct healthcare costs (€, 2013) associated with the procedure and management of complications. A total of 79 patients sequentially underwent GL XPS (n: 39) or TURP (n: 40) between July and October, 2013. Clinical outcomes were similar (94.9% and 92.5%, GL XPS and TURP, respectively) without significant differences (P=.67). The average direct cost per patient was reduced by €114 in GL XPS versus TURP patients; the cost was higher in the surgical phase with GL XPS (difference: €1,209; P<.001) but was lower in the post-surgical phase (difference: €-1,351; P<.001). The GreenLight XPS 180-W laser system is associated with a reduction in costs with respect to transurethral resection of prostate in the surgical treatment of LUTS secondary to PBH. This reduction is due to a shorter inpatient length of stay that offsets the cost of the new technology. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

Although splenic angioembolization (SAE) has been introduced and adopted in many trauma centers, the appropriate selection for and utility of SAE in trauma patients remains under debate. This study examined the outcomes of proximal SAE as part of a management algorithm for adult traumatic splenic injury compared with splenectomy. A retrospective cohort analysis was performed on all hemodynamically stable (HDS) blunt trauma patients with isolated splenic injury and computed tomographic (CT) evidence of active contrast extravasation that presented to a level 1 Trauma Center over a period of 5 years. The cohorts were defined by two separate 30 month periods and included 78 patients seen before (group I) and 76 patients seen after (group II) the introduction of an institutional SAE protocol. Demographics, splenic injury grade, and outcomes of the two groups were compared using Student's t test, or chi2 test. Analysis was by intention-to-treat. Six hundred eighty-two patients with blunt splenic injury were identified; 154 patients (29%) were HDS with CT evidence of active contrast extravasation. Group I (n = 78) was treated with splenectomy and group II (n = 76) was treated with proximal SAE. There was no difference in age (33 +/- 14 vs. 37 +/- 17 years), Injury Severity Score (31 +/- 13 vs. 29 +/- 11), or mortality (18% vs. 15%) between the two groups. However, the incidence of Adult Respiratory Distress Syndrome (ARDS) was 4-fold higher in those patients that underwent proximal SAE compared with those that underwent splenectomy (22% vs. 5%, p = 0.002). Twenty two patients failed nonoperative management (NOM) after SAE.

The current study reports the synthesis and characterization of tungstophosphoric acid and its acid silver salt supported on mesoporous molecular sieve SBA-15 and TiO 2 . Because silver salts are partially insoluble, the SBA-15 and TiO 2 supported silver acid salts were prepared by two step sequential impregnations. The synthesized catalysts were characterized by various physicochemical methods such as Fourier transform infrared and Raman spectroscopy, differential thermal analysis, thermogravimetric analysis, X-ray diffraction, scanning electron microscopy and nitrogen physisorption at −196 °C. It is observed that both active phases keep their Keggin-type structure after being supported on the supports while their specific surface area is considerably increased by deposition on mesoporous substrates. The results also indicated that the synthesized catalysts retained the morphology specific for each of the supports, while their thermal stability is increased in comparison with their active phases. The catalytic activity of the prepared catalysts was probed for the vapor phase dehydration of ethanol at 300 °C. Results revealed that all the catalysts show considerably improved catalytic activity in comparison to the bulk active phases. - Highlights: • SBA-15 and TiO 2 supported Ag 2 HPW 12 O 40 and H 3 PW 12 O 40 were prepared. • Active phases are uniformly dispersed without changing morphology of the substrates. • Composites are more thermally stable than active phases. • Composites exhibit high catalytic activity for gas phase ethanol dehydration

Full Text Available Objectives: Saffron is the stigma of Crocus sativus L., which has the potentials to play a role in the treatment of many diseases. Although many researches are now going on this precious spice, there are few data on saffron safety in human, especially in patients with chronic mental illnesses. This study aimed to evaluate the short-term safety and tolerability of both saffron and crocin (its major constituent in adult patients with schizophrenia. Materials and Methods: The capsules of saffron aqueous extract (SAE and crocin were used to evaluate short-term safety and tolerability in patients with schizophrenia. A double-blind, placebo-controlled study was performed on patients with schizophrenia. The patients were all male and were divided into three 22-patient groups. While receiving their normal treatment, they also received a 12 week treatment with SAE (15 mg twice daily, crocin (15 mg twice daily or placebo. Results: A total of 61 patients completed the trial; none of them reported a serious side effect. WBC count increased significantly in patients receiving saffron aqua extract (SAE, but it was within the normal range and had no clinical significance. Other hematologic components, markers of thyroid, liver and kidney or inflammation markers had no statistically significant difference among the groups. Conclusions: This study showed that SAE and crocin in doses of 15 mg twice daily were safely tolerated in patients with schizophrenia.

Lenin w Anglii

Mario Tronti

Full Text Available Lenin w Anglii to słynny tekst Trontiego otwierający pierwszy numer czasopisma Classe operaia, założonego po tym, jak Tronti wraz ze współpracownikami zerwał ze środowiskiem pierwszego operaizmu skupionego wokół Quaderni Rossi. To właśnie w tym tekście Tronti sformułował słynny „kopernikański zwrot w marksizmie”, zgodnie z którym punktem wyjścia analizy rzeczywistości społecznej i historii kapitalizmu powinna być walka klasy robotniczej, a nie prawa rozwoju kapitału. Do zdefiniowania zwrotu popchnęła Trontiego przedstawiona w tekście diagnoza sytuacji włoskiej klasy robotniczej w latach 60. Kontrowersyjne tezy Trontiego i jego radykalna postawa wpłynęły znacząco na dyskusje prowadzone na radykalnej włoskiej lewicy i na działania wielu aktywistów w latach 60. i 70.

We propose possible signatures of `exogamous' combinations between partons in the different W+ and W- hadron showers in e+e- -> W+W- events with purely hadronic final states. Within the space-time model for hadronic shower development that we have proposed previously, we find a possible difference of about 10 % between the mean hadronic multiplicity in such purely hadronic final states and twice the hadronic multiplicity in events in which one W decays hadronically and the other leptonically,...

Physical states and scaling properties of W gravities and W strings

International Nuclear Information System (INIS)

Das, S.R.; Dhar, A.; Rama, S.K.

1992-01-01

In this paper the authors discuss some physical aspects of W gravities and W strings. The authors identify global characteristics in W gravities (in addition to the usual Euler characteristic) and show how the dependence of the partition function on the various chemical potentials involves these quantities. The authors find the operators which create physical states in W 3 and W 4 gravities and discuss their relationship with screening operators. W strings are discussed in the framework of a natural way of coupling matter to W gravity, and the issues of extra dimensions and critical dimensions are clarified. The authors find a remarkable relationship between pure W gravities and ordinary gravity coupled to c < 1 unitary minimal models

Full Text Available Use of biodiesel produces engine oil dilution because of unburned biodiesel impinging on cold walls of the combustion chamber, being scrapped to the oil pan, and leading to changes of oil friction, wear and lubricity properties. In this paper, mixtures of SAE 15W-40 oil, which were contaminated by known percentages of the biodiesels from canola oil, peanut oil, soybean oil, and chicken fat, were tested in a pin-on-disk tribometer. A contact was employed of AISI 1018 steel disk and AISI 316 stainless-steel ball for pin material, and friction force and specific wear were measured. Wear on the disk surfaces showed that any degree of mineral-oil dilution by the tested biodiesels reduces the wear protection of engine oil even at small mixture percentages. However, these reductions were not substantially different than those observed for same percentages of dilution of mineral oil by fossil diesel. The tested mixture of oil contaminated with animal fat feedstock (e.g., chicken fat biodiesel showed the best wear behavior as compared to those for the other tested mixtures (of mineral oil with vegetable feedstock biodiesel dilutions. Obtained results are discussed as baseline for further studies in a renewable energy multidisciplinary approach on biofuels and biolubes.

Magnetic iron metal-silica and magnetite-silica nanocomposites have been prepared via temperature-programed reduction (TPR) of an iron oxide-SBA-15 (SBA: Santa Barbara Amorphous) composite. TPR of the starting SBA-15 supported Fe{sub 2}O{sub 3} generated Fe{sub 3}O{sub 4} and FeO as stepwise intermediates in the ultimate formation of Fe-SBA-15. The composite materials have been characterized by means of x-ray diffraction, high resolution transmission electron microscopy and SQUID (superconducting quantum interference device) magnetometry. The Fe oxide and metal components form a core, as nanoscale particles, that is entrapped in the SBA-15 pore network. Fe{sub 3}O{sub 4}-SBA-15 and Fe-SBA-15 exhibited superparamagnetic properties with a total magnetization value of 17 emu g{sup -1}. The magnetite-silica composite (at an Fe{sub 3}O{sub 4} loading of 30% w/w) delivered a magnetization that exceeded values reported in the literature or obtained with commercial samples. Due to the high pore volume of the mesoporous template, the magnetite content can be increased to 83% w/w with a further enhancement of magnetization.

:1998 określone zostały wymagania podsadzki zestalanej oraz dla mieszaniny do doszczelniania zrobów. (tab. 5), tylko dla części badań wskazane są konkretne wymagania ilościowe. Wyniki badań wymywalność zanieczyszczeń chemicznych oraz zawartości radionuklidów zostały omówione wcześniej. Właściwości zawiesin w stanie płynnym zestawiono w tabeli 6. oraz na rys. 7, 8 i 9., a parametry reologiczne wg modelu Binghama na rys. 10÷13. Wymagania w zakresie właściwości zestalonych zawiesin tj. wytrzymałości na jednoosiowe ściskanie oraz rozmakalności zostały ściśle określone dla podsadzki zestalanej jak i mieszaniny do doszczelniania zrobów (tab. 5). Zawiesiny przygotowane na bazie odpadów ze zgazowania węgla nie wykazują właściwości wiążących. Zarówno ze względu na wytrzymałość na jednoosiowe ściskanie (rys. 14) jak i rozmakalność (rys. 15) kwalifikują się jedynie, jako mieszaniny do doszczelniania zrobów. Przeprowadzone badania wstępnie potwierdziły możliwość zastosowania ubocznych produktów zgazowania pochodzących z instalacji bazujących na reaktorach dyspersyjnych, w technologiach górniczych charakterystycznych dla polskiego górnictwa podziemnego. Dla ostatecznego potwierdzenia konieczne są oczywiście badania dokładnie tych odpadów, które miałyby być stosowane w konkretnych kopalniach. Przyszłe wykorzystanie zastosowania odpadów z procesu zgazowania węgla, jako materiałów podsadzkowych zależy od wielu czynników, do których zaliczyć należą: dalszy rozwój technologii podsadzki hydraulicznej w górnictwie polskim, a także właściwości i dostępność tego typu materiałów powstałych ze zgazowania polskich węgli i/oraz w instalacjach na terenie Polski.

Data collected at LEP at centre-of-mass energies \\sqrt(s) = 189 - 209 GeV are used to study correlations of the spin of W bosons using e+e- -> W+W- -> lnqq~ events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e+e- -> W+W- -> lnqq~ and e+e- -> W+W- -> qq~qq~ events. Decay-plane correlations, consistent with zero and with the Standard Model predictions, are measured.

The aim of this study was to investigate the accumulation characteristics of tungsten (W) by different indica rice cultivars from the soil and to assess the potential risks to human health via dietary intake of W in rice consumption. A total of 153 rice (ear) samples of 15 cultivars and the corresponding surface soil samples were collected from 7 cities in Fujian Province of southeastern China. The available soil W were extracted using H 2 C 2 O 4 ·2H 2 O-(NH 4 ) 2 C 2 O 4 ·H 2 O at pH 3.3). Results showed that the total soil W ranged from 2.03 mg kg -1 to 15.34 mg kg -1  and available soil W ranged from 0.03 mg kg -1 to 1.61 mg kg -1 . The W concentration in brown rice varied from 7 μg kg -1 to 283 μg kg -1 and was significantly correlated with the available soil W. The highest mean TF avail (transfer factor based on available soil W) was 0.91 for Te-you 627 (hybrid, indica rice), whereas the lowest was 0.08 for Yi-you 673 (hybrid, indica rice). The TF avail decreased with the increase in available soil W, clay content, and cation exchange capacity. The consumption of the brown rice produced from the investigated areas in some cultivars by the present study may cause risks to human health.

The production of W-pairs is analysed in a data samplecollected by ALEPH at a mean centre-of-mass energy of 188.6 GeV,corresponding to an integrated luminosity of 174.2 pb^-1. Crosssections are given for different topologies of W decays intoleptons or hadrons. Combining all final states and assumingStandard Model branching fractions, the total W-pair cross sectionis measured to be 15.71 +- 0.34 (stat) +- 0.18 (syst) pb.Using also the W-pair data samples collected by ALEPH at lowercentre-of-mass energies, the decay branching fraction of the W bosoninto hadrons is measured to be BR (W > hadrons) = 66.97+- 0.65 (stat) +- 0.32 (syst) %, allowing a determination of theCKM matrix element |V(cs)|= 0.951 +- 0.030 (stat) +- 0.015 (syst).

Full Text Available Silne właściwości antyseptyczne olejków eterycznych znane są od wielu wieków. Są one produktami metabolizmu wtórnego roślin. Olejki eteryczne i ich składniki wykazują działanie hamujące wzrost wobec bakterii, grzybów, wirusów i pierwotniaków. Ich aktywność przeciwdrobnoustrojowa jest ściśle związana ze składem chemicznym. Do tej pory nie odnotowano doniesień o rosnącej oporności szczepów bakterii i grzybów na składniki olejków. Olejki eteryczne wykazują m.in. właściwości przeciwzapalne, przeciwbólowe i antyoksydacyjne. Do najbardziej skutecznych olejków o najsilniejszych właściwościach przeciwgrzybiczych należą olejki pozyskiwane z drzewa herbacianego, tymianku, oregano, cząbru, bazylii, szałwi, goździkowca i cynamonowca. Największą aktywnością charakteryzują się olejki zawierające fenole – tymol, karwakrol i eugenol. Olejki tymiankowy, oreganowy i cząbrowy zawierają tymol i karwakrol, natomiast pozyskiwane z goździkowca i z liści cynamonowca zawierają eugenol. Jeden z najbardziej efektywnych olejków jest pozyskiwany z drzewa herbacianego (Melaleuca alternifolia. Olejek ten wykazuje wysoką aktywność wobec Candida sp., Trichophyton sp. i Microsporum sp. Olejki tymiankowy, oreganowy i rozmarynowy ze względu na szerokie spektrum aktywności mogą być polecane w leczeniu zakażeń wywoływanych przez Candida albicans, Trichophyton sp., Epidermophyton floccosum i Microsporum canis. Olejek goździkowy i cynamonowy z liści wykazują znaczące działanie hamujące wobec Aspergillus flavus, Aspergillus parasiticus, Candida albicans i Cryptococcus neoformans. Olejki eteryczne oraz ich składniki mogą posiadać silne działanie immunostymulujące, zaliczamy do nich: olejek sosnowy, cytrynowy, geraniowy, a-pinen. Olejki eteryczne znalazły zastosowanie w leczeniu infekcji dermatologicznych pochodzenia grzybiczego. Dobre wyniki przynosi również stosowanie olejków w ginekologii i w terapii

On colour rearrangement in hadronic W+W- events

International Nuclear Information System (INIS)

Sjoestrand, T.; Khoze, V.A.

1994-01-01

We discuss the possibility of colour rearrangement in e + e - →W + W - →q 1 anti q 2 q 3 anti q 4 events, i.e. that the original colour singlets q 1 anti q 2 and q 3 anti q 4 may be transmuted, for instance, into new singlets q 1 anti q 4 and q 3 anti q 2 . The effects on event properties could be quite large if such a rearrangement would occur instantaneously, so that gluon emission would be restricted to each of the new singlets separately. We argue that such a scenario is unlikely for two reasons. Firstly, the W + and W - usually decay at separate times after the W + W - production, which leads to large relative phases for energetic radiation off the two constituents of a rearranged system, and a corresponding dampening of the QCD cascades. Secondly, within the perturbative scenario the colour transmutation appears only in order α s 2 and is colour-suppressed. Colour reconnection at longer time scales is quite feasible, however, and may affect the fragmentation phase. If so, the nature of non-perturbative QCD can be probed in a new way. We formulate several alternative toy models and use these to estimate the colour reconnection probability as a function of the event kinematics. Possible consequences for LEP 2 events are illustrated, with special attention to systematic errors in W mass determinations. (orig.)

A 20-cell PEFC stack was designed and built. Resin impregnated graphite was used as bipolar plate material. The air cooling of the stack was optimized by introducing high surface structures into the open space of the cooling plates. At {eta} (H{sub 2} LHV) = 0.5 a power of 880 W was obtained under conditions of low gas-pressures of 1.15 bar{sub a}. The auxiliary power for process air supply and cooling at 880 W power is less than 7% of the power output, indicating that the described system may be operated at a high efficiency.

Inconsistencies in data on serious adverse events (SAEs) and mortality in ClinicalTrials.gov and corresponding journal articles pose a challenge to research transparency. The objective of this study was to compare data on SAEs and mortality from clinical trials reported in ClinicalTrials.gov and corresponding journal articles with US Food and Drug Administration (FDA) medical reviews. We conducted a cross-sectional study of a randomly selected sample of new molecular entities approved during the study period 1 January 2013 to 31 December 2015. We extracted data on SAEs and mortality from 15 pivotal trials from ClinicalTrials.gov and corresponding journal articles (the two index resources), and FDA medical reviews (reference standard). We estimated the magnitude of deviations in rates of SAEs and mortality between the index resources and the reference standard. We found deviations in rates of SAEs (30% in ClinicalTrials.gov and 30% in corresponding journal articles) and mortality (72% in ClinicalTrials.gov and 53% in corresponding journal articles) when compared with the reference standard. The intra-class correlation coefficient between the three resources was 0.99 (95% confidence interval [CI] 0.98-0.99) for SAE rates and 0.99 (95% CI 0.97-0.99) for mortality rates. There are differences in data on rates of SAEs and mortality in randomized clinical trials in both ClinicalTrials.gov and journal articles compared with FDA reviews. Further efforts should focus on decreasing existing discrepancies to enhance the transparency and reproducibility of data reporting in clinical trials.

Highlights: ► NiW catalysts supported on TiO 2 nanotubes, titania and alumina. ► The best results are obtained with NiW/TiO 2 nanotubes in hydrodesulfurization (HDS) of thiophene. ► Active phase is Ni-WO x S y . ► Electronic promotion of W by Ti. - Abstract: High surface area TiO 2 nanotubes (Ti-NT) synthesized by alkali hydrothermal method were used as a support for NiW hydrodesulphurization catalyst. Nickel salt of 12-tungstophosphoric acid – Ni 3/2 PW 12 O 40 was applied as oxide precursor of the active components. The catalyst was characterized by S BET , XRD, UV–vis DRS, Raman spectroscopy, XPS, TPR and HRTEM. The results obtained were compared with those for the NiW catalysts prepared over high surface area titania and alumina supports. A polytungstate phase evidenced by Raman spectroscopy was observed indicating the destruction of the initial heteropolyanion. The catalytic experiments revealed two times higher thiophene conversion on NiW catalyst supported on Ti-NT than those of catalysts supported on alumina and titania. Increased HDS activity of the NiW catalyst supported on Ti-NT could be related to a higher amount of W oxysulfide entities interacting with Ni sulfide particles as consequence of the electronic effects of the Ti-NT observed with XPS analysis.

Critical Power (CP) and W' are often determined using multi-day testing protocols. To investigate this cumbersome testing method, the purpose of this study was to compare the differences between the conventional use of a 24-h inter-trial recovery time with those of 3 h and 30 min for the determination of CP and W'. 9 moderately trained cyclists performed an incremental test to exhaustion to establish the power output associated with the maximum oxygen uptake (p[Formula: see text] max ), and 3 protocols requiring time-to-exhaustion trials at a constant work-rate performed at 80%, 100% and 105% of p[Formula: see text] max. Design: Protocol A utilised 24-h inter-trial recovery (CP 24 /W' 24 ), protocol B utilised 3-h inter-trial recovery (CP 3 /W' 3 ), and protocol C used 30-min inter-trial recovery period (CP 0.5 /W' 0.5 ). CP and W' were calculated using the inverse time (1/t) versus power (P) relation (P = W'(1/t) + CP). 95% Limits of Agreement between protocol A and B were -9 to 15 W; -7.4 to 7.8 kJ (CP/W') and between protocol A and protocol C they were -27 to 22 W; -7.2 to 15.1 kJ (CP/W'). Compared to criterion protocol A, the average prediction error of protocol B was 2.5% (CP) and 25.6% (W'), whilst for protocol C it was 3.7% (CP) and 32.9% (W'). 3-h and 30-min inter-trial recovery time protocols provide valid methods of determining CP but not W' in cycling.

The transition metal-substituted heteropolyoxoanion, Cd 4 (H 2 O) 2 (As 2 W 15 O 56 ) 2 12- (As 4 W 30 Cd 4 ), is one of the trivacant Dawson derivatives. Its redox electrochemistry has been studied in acid buffer solutions using cyclic voltammetry. It exhibited three steps of four-electron redox waves attributed to redox processes of the tungsten-oxo framework. Through layer-by-layer assembly, the compound was first successfully immobilized on a 4-aminobenzoic acid modified glassy carbon electrode surface by alternate deposition with a quaternized poly(4-vinylpyridine) partially complexed with [Os(bpy) 2 Cl] 2+/+ (denoted as QPVP-Os). Thus, prepared multilayer films have been characterized by cyclic voltammetry (CV), X-ray photoelectron spectroscopy (XPS) and UV-vis spectroscopy (UV-vis). The electrocatalytic activities of the multilayer films containing As 4 W 30 Cd 4 have been investigated on the reduction of three substrates of important analytical interests, NO 2 - , BrO 3 - and IO 3 - . And with the increase of the number of As 4 W 30 Cd 4 layers, the catalytic current towards the reduction of BrO 3 - was enhanced and the catalytic potential shifted positively

The formation of beta-carotene detergent micelles and their conversion into retinal by recombinant human beta,beta-carotene 15,15'-monooxygenase was optimized under aqueous conditions. Toluene was the most hydrophobic among the organic solvents tested; thus, it was used to dissolve beta-carotene, which is a hydrophobic compound. Tween 80 was selected as the detergent because it supported the highest level of retinal production among all of the detergents tested. The maximum production of retinal was achieved in detergent micelles containing 200 mg/L of beta-carotene and 2.4% (w/v) Tween 80. Under these conditions, the recombinant enzyme produced 97 mg/L of retinal after 16 h with a conversion yield of 48.5% (w/w). The amount of retinal produced, which is the highest ever reported, is a result of the ability of our system to dissolve large amounts of beta-carotene.

2005-01-01

Data collected at LEP at centre-of-mass energies √(s)=189-209 GeV are used to study correlations of the spin of W bosons using e + e - →W + W - →lνq anti q events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e + e - →W + W - →lνq anti q and e + e - →W + W - →q anti qq anti q events. Decay-plane correlations are measured to be consistent with the Standard Model predictions. (orig.)

Microstructures of as-cast 28 wt.%Cr–2.6 wt.%C irons containing (0–10)wt.%W with the Cr/C ratio about 10 were studied and related to their hardness. The experimental irons were cast into dry sand molds. Microstructural investigation was performed by light microscopy, X-ray diffractometry, scanning electron microscopy, transmission electron microscopy and energy-dispersive X-ray spectrometry. It was found that the irons with 1 to 10 wt.%W addition was hypereutectic containing large primary M{sub 7}C{sub 3}, whereas the reference iron without W addition was hypoeutectic. The matrix in all irons was austenite, partly transformed to martensite during cooling. The volume fractions of primary M{sub 7}C{sub 3} and the total carbides increased, but that of eutectic carbides decreased with increasing the W content of the irons. W addition promoted the formation of W-rich M{sub 7}C{sub 3}, M{sub 6}C and M{sub 23}C{sub 6}. At about 4 wt.%W, two eutectic carbides including M{sub 7}C{sub 3} and M{sub 6}C were observed together with primary M{sub 7}C{sub 3}. At 10 wt.%W, multiple carbides including primary M{sub 7}C{sub 3}, fish-bone M{sub 23}C{sub 6}, and M{sub 6}C were observed. M{sub x}C where x = 3 or less has not been found due possibly to the high M/C ratio in the studied irons. W distribution to all carbides has been determined increasing from ca. 0.3 to 0.8 in mass fraction as the W content in the irons was increased. W addition led to an increase in Vickers macro-hardness of the irons up to 671 kgf/(mm){sup 2} (HV30/15) obtained from the iron with 10 wt.%W. The formation of primary M{sub 7}C{sub 3} and aggregates of M{sub 6}C and M{sub 23}C{sub 6} were the main reasons for hardness increase, indicating potentially improved wear performance of the as-cast irons with W addition. - Highlights: • W addition at 1 up to 10 wt.%W to Fe–28Cr–2.6C produced “hypereutectic” structure. • W addition promoted the formation of W-rich M{sub 7}C{sub 3}, M{sub 6}C and M
