Pentosan Polysulfate: A Novel Therapy for the Mucopolysaccharidoses  

PubMed Central

Background Pentosan polysulfate (PPS) is an FDA-approved, oral medication with anti-inflammatory and pro-chondrogenic properties. We have previously shown that animal models of the mucopolysaccharidoses (MPS) exhibit significant inflammatory disease, contributing to cartilage degeneration. Enzyme replacement therapy (ERT) only partly reduced inflammation, and anti-TNF-alpha antibody therapy significantly enhanced clinical and pathological outcomes. Here we describe the use of PPS for the treatment of MPS type VI rats. Methodology/Principal Findings Treatment began during prenatal development and at 1 and 6 months of age. All animals were treated until they were 9 months old. Significant reductions in the serum and tissue levels of several inflammatory markers (e.g., TNF-alpha, MIP-1alpha and RANTES/CCL5) were observed, as was reduced expression of inflammatory markers in cultured articular chondrocytes. ADAMTS-5/aggrecanase-2 levels also were reduced in chondrocytes, consistent with an elevation of serum tissue inhibitor of metalloproteinase 1. Marked improvements in motility and grooming behavior occurred, along with a reduction in eye and nasal secretions and a lessening of the tracheal deformities. MicroCT and radiographic analyses further revealed that the treated MPS skulls were longer and thinner, and that the teeth malocclusions, misalignments and mineral densities were improved. MicroCT analysis of the femurs and vertebrae revealed improvements in trabecular bone mineral densities, number and spacing in a subset of treated MPS animals. Biomechanical assessments of PPS-treated spines showed partially restored torsional behaviors, suggesting increased spinal stability. No improvements were observed in cortical bone or femur length. The positive changes in the PPS-treated MPS VI rats occurred despite glycosaminoglycan accumulation in their tissues. Conclusions Based on these findings we conclude that PPS could be a simple and effective therapy for MPS that might provide significant clinical benefits alone and in combination with other therapies.

Pentosan polysulfate treatment ameliorates motor function with increased serum soluble vascular cell adhesion molecule-1 in HTLV-1-associated neurologic disease.  

PubMed

The main therapeutic strategy against human T lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) characterized by lower extremity motor dysfunction is immunomodulatory treatment, with drugs such as corticosteroid hormone and interferon-?, at present. However, there are many issues in long-term treatment with these drugs, such as insufficient effects and various side effects. We now urgently need to develop other therapeutic strategies. The heparinoid, pentosan polysulfate sodium (PPS), has been safely used in Europe for the past 50 years as a thrombosis prophylaxis and for the treatment of phlebitis. We conducted a clinical trial to test the effect of subcutaneous administration of PPS in 12 patients with HAM/TSP in an open-labeled design. There was a marked improvement in lower extremity motor function, based on reduced spasticity, such as a reduced time required for walking 10 m and descending a flight of stairs. There were no significant changes in HTLV-I proviral copy numbers in peripheral blood contrary to the inhibitory effect of PPS in vitro for intercellular spread of HTLV-I. However, serum soluble vascular cell adhesion molecule (sVCAM)-1 was significantly increased without significant changes of serum level of chemokines (CXCL10 and CCL2). There was a positive correlation between increased sVCAM-1and reduced time required for walking 10 m. PPS might induce neurological improvement by inhibition of chronic inflammation in the spinal cord, through blocking the adhesion cascade by increasing serum sVCAM-1, in addition to rheological improvement of the microcirculation. PPS has the potential to be a new therapeutic tool for HAM/TSP. PMID:24671717

SuFEx-based synthesis of polysulfates.  

PubMed

High-molecular-weight polysulfates are readily formed from aromatic bis(silyl ethers) and bis(fluorosulfates) in the presence of a base catalyst. The reaction is fast and proceeds well under neat conditions or in solvents, such as dimethyl formamide or N-methylpyrrolidone, to provide the desired polymers in nearly quantitative yield. These polymers are more resistant to chemical degradation than their polycarbonate analogues and exhibit excellent mechanical, optical, and oxygen-barrier properties. PMID:25100330

Synthesis and biological evaluation of polysulfated oligosaccharide glycosides as inhibitors of angiogenesis and tumor growth.  

PubMed

A series of polysulfated penta- and tetrasaccharide glycosides containing alpha(1-->3)/alpha(1-->2)-linked mannose residues were synthesized as heparan sulfate (HS) mimetics and evaluated for their ability to inhibit angiogenesis. The compounds bound tightly to angiogenic growth factors (FGF-1, FGF-2, and VEGF) and strongly inhibited heparanase activity. In addition, the compounds exhibited potent activity in cell-based and ex vivo assays indicative of angiogenesis, with tetrasaccharides exhibiting activity comparable to that of pentasaccharides. Selected compounds also showed good antitumor activity in vivo in a mouse melanoma (solid tumor) model resistant to the phase III HS mimetic 1 (muparfostat, formerly known as PI-88). The lipophilic modifications also resulted in reduced anticoagulant activity, a common side effect of HS mimetics, and conferred a reasonable pharmacokinetic profile in the rat, as exemplified by the sulfated octyl tetrasaccharide 5. The data support the further investigation of this class of compounds as potential antiangiogenic, anticancer therapeutics. PMID:20128596

Effects of Low Level Water-soluble Pentosans, Alkaline-extractable Pentosans, and Xylanase on the Growth and Development of Broiler Chicks  

PubMed Central

This study investigated the effects of low levels of water-soluble pentosans (WSP), alkaline-extractable pentosans (AEP), and xylanase on the growth and organ development of broiler chicks. Three hundred and fifty 1-d-old female broiler chicks were randomly allocated into seven experimental groups of five pen replicates, with ten chicks per replicate. The control group consumed a corn-soybean meal-based diet. Six dietary treatment groups consumed the basal diet supplemented with one of the following: WSP at 50 mg/kg (WSP50) or 100 mg/kg (WSP100); AEP at 50 mg/kg (AEP50) or 100 mg/kg (AEP100); or xylanase at 3 mg/kg (Xase3) or 6 mg/kg (Xase6). Data including the body weight, digestive organ weights, gut length, rectal digesta viscosity, and gut microflora and pH were collected on d 5, 10, and 15. When compared to the control group, WSP50 promoted body weight gain and organ growth throughout the study, calculated as 3-d averages (p<0.05). WSP100 increased weight gain and enhanced organ development (proventriculus, gizzard, and gut) on d 10 (p<0.05), but the 3-d averages were not different from the control group except for the weight of gizzard. Both Xase3 and Xase6 increased the 3-d average weight gain and the growth of the gizzard (p<0.05). WSP50 increased the digesta viscosity compared to Xase3 on d 10 and 15 (p<0.05). WSP50, Xase3, and Xase6 increased the concentration of Lactobacillus in the rectum when compared to the control group (p<0.05), but only Xase3 lowered the digesta pH in the ileum and cecum on d 10 and 15. AEP had minimal influence on the growth and organ development of broilers. The results showed that low levels of WSP, AEP, and xylanase had different effects and underlying mechanisms on the growth and organ development of broiler chicks. WSP50 could increase the growth performance of broilers fed a corn-soybean meal-based diet. PMID:25049914

Further investigations into the potentiation of infection by intra-articular injection of polysulfated glycosaminoglycan and the effect of filtration and intra-articular injection of amikacin.  

PubMed

Polysulfated glycosaminoglycan (PSGAG) recently have been reported to potentiate the infectivity of Staphylococcus aureus in horses with experimentally induced septic arthritis. Four groups of 8 horses each had 1 midcarpal joint injected with approximately 33 viable colony-forming units (CFU) of S aureus plus either 1 ml of saline solution (group 1), 250 mg of PSGAG (group 2), 250 mg of PSGAG passed through a 0.6-microns filter (group 3), or 250 mg of PSGAG plus 125 mg of amikacin (group 4). Horses that developed clinical signs consistent with sepsis were euthanatized, and samples were collected at necropsy. Horses that survived had samples obtained by use of arthroscopy at days 13 and 14 after injection. Staphylococcus aureus was isolated from 1 group-1 horse, 8 group-2 horses, and 7 of 7 group-3 horses that met protocol, but was not isolated from any group-4 horses. All 16 aforementioned horses had clinical signs, results of synovial fluid analysis, and gross pathologic and synovial membrane histopathologic findings that were consistent with septic arthritis. Polysulfated glycosaminoglycan (250 mg) increased the infectivity of 33 CFU of S aureus (P = 0.001); filtering the PSGAG had no effect. Intra-articular injection of 125 mg of amikacin immediately after inoculating the joint with 33 CFU of S aureus significantly (P = 0.001) decreased potentiation of infection by the PSGAG.

Protection of the blood-brain barrier by pentosan against amyloid-?-induced toxicity.  

PubMed

Endothelial cells of brain capillaries forming the blood-brain barrier play an important role in the pathogenesis and therapy of Alzheimer's disease. Amyloid-? (A?) peptides are key pathological elements in the development of the disease. A blood-brain barrier model, based on primary rat brain endothelial cells was used in which the barrier properties were induced by glial cells. The effects of amyloid peptides have been tested on cell viability and barrier functions. A? showed toxic effects on primary rat brain endothelial cells measured by MTT dye conversion and the lactate dehydrogenase release. Morphologically cytoplasmic vacuolization, disruption of the structure of cytoplasmic organelles and tight junctions could be observed in brain endothelial cells. Treatment with A?1-42 decreased the electrical resistance, and increased the permeability of brain endothelial cell monolayers for both fluorescein and albumin. Serum amyloid P component which stabilizes A? fibrils in cortical amyloid plaques and cerebrovascular amyloid deposits significantly potentiated the barrier-weakening effect of A?1-42. Sulfated polysaccharide pentosan could decrease the toxic effects of A? peptides in brain endothelial cells. It could also significantly protect the barrier integrity of monolayers from damaging actions of peptides. Pentosan modified the size, and significantly decreased the number of amyloid aggregates demonstrated by atomic force microscopy. The present data further support the toxic effects of amyloid peptides on brain endothelial cells, and can contribute to the development of molecules protecting the blood-brain barrier in Alzheimer's disease.

Comparison of the effect of polysulfated glycosaminoglycan, corticosteroids, and sodium hyaluronate in the potentiation of a subinfective dose of Staphylococcus aureus in the midcarpal joint of horses.  

PubMed

Four groups of 8 horses each had 1 midcarpal joint injected with 33 colony-forming units (CFU) of viable Staphylococcus aureus plus: 1 ml of saline solution (group 1, control), 250 mg of polysulfated glycosaminoglycan (PSGAG, group 2), 100 mg of methylprednisolone acetate (group 3), or 20 mg of sodium hyaulronate (group 4). Horses were euthanatized, and samples were obtained on the basis of clinical signs of septic arthritis that were nonresponsive to phenylbutazone administration. One group-1 horse, all 8 group-2 horses, 3 group-3 horses, and 4 group-4 horses were culture-positive for S aureus and had clinical signs, results of synovial fluid analysis, and histopathologic findings that were consistent with sepsis. The addition of 250 mg of PSGAG increased the development of sepsis significantly (P = 0.001), compared with results in control horses. Differences in the development of sepsis between horses injected with methylprednisolone acetate or sodium hyaluronate and control horses were not significant. PMID:2610426

Pentosan-derived water-soluble carbon nano dots with substantial fluorescence: Properties and application as a photosensitizer  

NASA Astrophysics Data System (ADS)

The hydrothermal carbonization of monosaccharides and polysaccharides is widely used in the production of carbonaceous material with a desired structure. However, the liquid products are regarded as waste and discarded. Here, we report a facile approach for the synthesis of water-soluble carbon nano dots (CNDs) with substantial fluorescence from the liquid by-products of the hydrothermal carbonization of pentosan, thus the by-products of pulp refining. The synthesized CNDs are monodispersed spheres with abundant oxygen-containing groups and they have an average size of 30 nm. Quantum yield measurements revealed CNDs with substantial green photoluminescence (PL) without passivation. Additionally, excitation was independent, pH-sensitive and stable. The use of CNDs as a photosensitizer in the CNDs/TiO2 system for methylene blue (MB) degradation under visible light irradiation is attractive. The spectral response range of the CNDs/TiO2 system can be widened from the UV region to a part of the visible light region (400-550 nm).

In vitro hemorheological effects of parenteral agents used in peripheral arterial disease  

NASA Astrophysics Data System (ADS)

Peripheral arterial disease (PAD) is a frequent manifestation of systemic atherosclerosis. In PAD hemorheological parameters were defined as risk factors in a number of studies and several therapeutic agents were tried in these conditions. Our study aims to investigate and compare the in vitro hemorheological effects of various drugs generally used in the parenteral treatment of intermittent claudication and critical limb ischemia. Blood samples of healthy male volunteers were incubated with iloprost, alprostadil, pentoxifylline, sulodexide or pentosan polysulfate at calculated therapeutic serum concentration. Hematocrit (Hct) was determined by microhematocrit centrifuge. Plasma and apparent whole blood viscosities (WBV) were evaluated by capillary viscometer. Red blood cell aggregation was measured by LORCA (laserassisted optical rotational cell analyzer) aggregometer, and LORCA ektacytometer was used for measuring erythrocyte deformability at 37°C. Iloprost, alprostadil, and pentoxifylline incubation did not have any significant effect on plasma and apparent WBV. Elongation index increased in samples incubated with alprostadil at low shear stresses 0.95 and 0.53 Pa (p < 0.05). Sulodexide significantly improved WBV and Hct/WBV ratio (p < 0.05). Incubation with pentosan polysulfate resulted in higher WBV, lower Hct/WBV ratio and deterioration in the aggregation parameters (p < 0.05). Sulodexide may have beneficial effect on a macrorheological parameter; alprostadil may improve a microrheological parameter. Hemorheological alterations could be important in PAD patients with hampered vasodilator capacity.

[The complexity of chronic pelvic pain exemplified by the condition currently called interstitial cystitis. Part 2: Treatment].  

PubMed

The so-called interstitial cystitis is a chronic pain syndrome rather than a purely end organ disease of the urinary bladder. New suggestions for definitions and nomenclature take this into consideration. Since aetiology and pathogenesis are still unknown a treatment of the cause is still not possible. There are neither evidence-based treatment algorithms nor a so-called standard therapy. Numerous therapeutic approaches have been tried up to now. These attempts can be divided into oral, intravesical, surgical and physical procedures. There are also meaningful supplementary therapy procedures beyond the boundaries of classical school medicine. The WHO staging scheme provides the basis for every pain therapy. For the oral therapeutic procedures in current use the following medications with differing levels of evidence have been recommended: amitriptylin, hydroxyzin, pentosan polysulfate. Many other orally administered drugs have also been used although in many cases evidence of efficacy is lacking, these included anticonvulsants, L-arginine and various immunomodulators and immunosuppressants. Among the intravesical therapeutic procedures botulinum toxin A, dimethyl sulfoxide, heparin and glycosaminoglycan substitutes have been used. For the physical procedures, besides bladder distension, hyperbaric oxygen therapy shows efficacy. When the conventional therapeutic methods fail, surgical (partial) removal of the urinary bladder or urinary diversion procedures represent the therapeutic ultimo ratio. There are hardly any controlled studies on alternative curative procedures although rather good results have been obtained in chronic pelvic pain syndrome with acupuncture as an additional therapeutic modality.

Heparan Sulfates and Coxsackievirus-Adenovirus Receptor: Each One Mediates Coxsackievirus B3 PD Infection  

PubMed Central

Amino acid exchanges in the virus capsid protein VP1 allow the coxsackievirus B3 variant PD (CVB3 PD) to replicate in decay accelerating factor (DAF)-negative and coxsackievirus-adenovirus receptor (CAR)-negative cells. This suggests that molecules other than DAF and CAR are involved in attachment of this CVB3 variant to cell surfaces. The observation that productive infection associated with cytopathic effect occurred in Chinese hamster ovary (CHO-K1) cells, whereas heparinase-treated CHO-K1 cells, glucosaminoglycan-negative pgsA-745, heparan sulfate (HS)-negative pgsD-677, and pgsE-606 cells with significantly reduced N-sulfate expression resist CVB3 PD infection, indicates a critical role of highly sulfated HS. 2-O-sulfate-lacking pgsF-17 cells represented the cell line with minimum HS modifications susceptible for CVB3 PD. Inhibition of virus replication in CHO-K1 cells by polycationic compounds, pentosan polysulfate, lung heparin, and several intestinal but not kidney HS supported the hypothesis that CVB3 PD uses specific modified HS for entry. In addition, recombinant human hepatocyte growth factor blocked CVB3 PD infection. However, CAR also mediates CVB3 PD infection, because this CVB3 variant replicates in HS-lacking but CAR-bearing Raji cells, infection could be prevented by pretreatment of cells with CAR antibody, and HS-negative pgsD-677 cells transfected with CAR became susceptible for CVB3 PD. These results demonstrate that the amino acid substitutions in the viral capsid protein VP1 enable CVB3 PD to use specific modified HS as an entry receptor in addition to CAR. PMID:12941917

Unfavourable results in hypospadias  

PubMed Central

Hypospadias urethroplasty is considered difficult as the complications and unfavourable results are not uncommon. At the turn of the century, due to a better understanding of applied anatomy of hypospadias, new techniques were developed which significantly brought down the complication rate. However unfavourable results are still disturbing. An algorithm for selection of surgery has been presented. Forty three secondary surgeries were performed over 3 years for correction of unfavourable results. The urethrocutaneous fistula was the most common (21%) followed by meatal stenosis (14%) and narrow neourethra (14%). Common unfavourable results have been discussed. On the basis of experience with a large number of hypospadias urethroplasty ‘tips to avoid or minimise unfavourable results’ have been presented. However, one should assess the final outcome of urethroplasty using hypospadias objective scoring evaluation. PMID:24501477

$?\\to ??$ results in nuclei  

E-print Network

The Crystal Ball ($CB$) collaboration at $BNL$ has recently presented results regarding a study of the $\\pi^- A \\to \\pi^0\\pi^0 A^\\prime$ reaction on $H, D, C, Al$ and $Cu$, using a nearly 4$\\pi$ detector. Similar results, but for the $\\pi^+ A \\to \\pi^+\\pi^{\\pm} A^\\prime$ reaction on $^{2}H$, $^{12}C$, $^{40}Ca$, and $^{208}Pb$, have been published earlier by the $CHAOS$ collaboration at $TRIUMF$. In this Brief Report a comparison of the results of the two measurements is made, which shows that the $CHAOS$ and $CB$ data share relevant common features. In particular, the increase in strength as a function of A seen in the near-threshold $\\pi^+ \\pi^-$ invariant mass spectra reported by the $CHAOS$ group, is also seen in the $\\pi^0 \\pi^0$ CB data, when the results from the two groups are compared in a way which accounts for the different acceptances of the two experiments.

The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first nine runs of SAGE II give a capture rate of 66{sub -13}{sup +18} (stat) {sub -7}{sup +5} (sys) SNU. Combined with the SAGE I result of 73{sub -16}{sup +18} (stat) {sub -7}{sup 5} (sys) SNU, the capture rate is 69{sub -11}{sup +11} (stat) {sub -7}{sup +5} (sys) SNU. This represents only 52%--56% of the capture rate predicted by different Standard Solar Models.

Explaining embodied cognition results.  

PubMed

From the late 1950s until 1975, cognition was understood mainly as disembodied symbol manipulation in cognitive psychology, linguistics, artificial intelligence, and the nascent field of Cognitive Science. The idea of embodied cognition entered the field of Cognitive Linguistics at its beginning in 1975. Since then, cognitive linguists, working with neuroscientists, computer scientists, and experimental psychologists, have been developing a neural theory of thought and language (NTTL). Central to NTTL are the following ideas: (a) we think with our brains, that is, thought is physical and is carried out by functional neural circuitry; (b) what makes thought meaningful are the ways those neural circuits are connected to the body and characterize embodied experience; (c) so-called abstract ideas are embodied in this way as well, as is language. Experimental results in embodied cognition are seen not only as confirming NTTL but also explained via NTTL, mostly via the neural theory of conceptual metaphor. Left behind more than three decades ago is the old idea that cognition uses the abstract manipulation of disembodied symbols that are meaningless in themselves but that somehow constitute internal "representations of external reality" without serious mediation by the body and brain. This article uniquely explains the connections between embodied cognition results since that time and results from cognitive linguistics, experimental psychology, computational modeling, and neuroscience.

The promise of next-generation light sources depends on the availability of ultra-low emittance electron sources. One method of producing low transverse emittance beams is to generate a low longitudinal emittance beam and exchange it with a large transverse emittance. Experiments are underway at Fermilab's A0 Photoinjector and ANL's Argonne Wakefield Accelerator using the exchange scheme of Kim and Sessler. The experiment at the A0 Photoinjector exchanges a large longitudinal emittance with a small transverse emittance. AWA expects to exchange a large transverse emittance with a small longitudinal emittance. In this paper we discuss recent results at A0 and AWA and future plans for these experiments.

Early physics results.  

PubMed

For the past year, experiments at the Large Hadron Collider (LHC) have started exploring physics at the high-energy frontier. Thanks to the superb turn-on of the LHC, a rich harvest of initial physics results have already been obtained by the two general-purpose experiments A Toroidal LHC Apparatus (ATLAS) and the Compact Muon Solenoid (CMS), which are the subject of this report. The initial data have allowed a test, at the highest collision energies ever reached in a laboratory, of the Standard Model (SM) of elementary particles, and to make early searches Beyond the Standard Model (BSM). Significant results have already been obtained in the search for the Higgs boson, which would establish the postulated electro-weak symmetry breaking mechanism in the SM, as well as for BSM physics such as Supersymmetry (SUSY), heavy new particles, quark compositeness and others. The important, and successful, SM physics measurements are giving confidence that the experiments are in good shape for their journey into the uncharted territory of new physics anticipated at the LHC.

Recent Results from HAPPEX  

SciTech Connect

New measurements of the parity-violating asymmetry in elastic scattering of 3GeV electrons off hydrogen and helium-4 targets at theta{sub lab} = 6 degrees are reported. The helium-4 result is A = (+6.40 {+-} 0.23 (stat) {+-} 0.12 (syst)) * 10{sup -6}. The hydrogen result is A = (-1.58 {+-} 0.12 (stat) {+-} 0.04 (syst)) * 10{sup -6}. The asymmetry for hydrogen is a function of a linear combination of G{sub E}{sup s} and G{sub M}{sup s}, the strange quark contributions to the electric and magnetic form factors of the nucleon respectively, and that for helium-4 is a function solely of G{sub E}{sup s}. The combination of the two measurements separates G{sub E}{sup s} and G{sub M}{sup s} and provide new limits on the role of strange quarks in the nucleon charge and magnetization distributions. We extract G{sub E}{sup s} = 0.002 {+-} 0.014 {+-} 0.007 at Q{sup 2} = 0.077 GeV{sup 2} and G{sub E}{sup s} + 0.09 G{sub M}{sup s} = 0.007 {+-} 0.011 {+-} 0.006 at Q{sup 2} = 0.109 GeV{sup 2}.

ASCA Results on ULXs  

NASA Astrophysics Data System (ADS)

We review ASCA results on Ultra-Luminous Comact X-ray sources (ULXs), knwon for a long time in arm regions of nearby spiral galaxies. Although their high X-ray luminosity (typically 1039-40 erg/s) and variability suggest accreting ~ 100 Mo black holes, their spectral signature remained poorly known. With ASCA, we have found that ULXs exhibit X-ray spectra very similar to those of Galactic/Magellanic black-hole binaries, represented by either a multi-color disk blackbody model or a single power-law model (Makishima et al., ApJ 535, 362). Two ULXs in IC342 have shown remarkable transitions between these two characteristic states (Kubota et al., ApJ 547,119L). Furthermore, one of them may have an X-ray periodicity at ~ 30 hours, which is appropriate for a binary period of a semi-detached binary composed of a ~ 100 Mo black hole and ~ 100 Mo main-sequence star. All these ASCA results significantly reinforce the interpretation of ULXs in terms of accreting ~ 100 Mo black holes. However, the accretion disk temperatures of ULXs are systematically higher than those of the ordinary black-hole binaries. This problem may be solved by assuming a significant black-hole rotation and/or an optically-thick ADAF scenario.

The Californium Rare Ion Breeder Upgrade (CARIBU) of the ATLAS superconducting linac facility aims at providing low energy and reaccelerated neutron-rich radioactive beams to address key nuclear physics, astrophysics and application issues. These beams are obtained from fission fragments of a 1 Ci 252Cf source, thermalized and collected into a low-energy particle beam by a helium gas catcher, mass analyzed by an isobar separator, and charge breed to higher charge states for acceleration in ATLAS. The method described is fast and universal and short-lived isotope yield scale essentially with Californium fission yields. The facility is now commissioned and operating with a 100 mCi source which has yielded extracted low-energy mass separated radioactive beams at intensities in excess of 100000 ions per second. Radioactive beams have been charge bred with an efficiency of up to 12% and reaccelerated to 6 MeV/u. Commissioning results, together with the results from first astrophysics experiments at CARIBU using the beams from the 100 mCi source will be presented. The final 1 Ci source is currently under fabrication and is expected to be installed by the end of the year.

Unfavourable results in pollicisation  

PubMed Central

Pollicisation of the index finger is perhaps one of the most complex and most rewarding operations in hand and plastic surgery. It however has a steep learning curve and demands very high skill levels and experience. There are multiple pitfalls and each can result in an unfavourable result. In essence we need to: Shorten the Index, recreate the carpo metacarpal joint from the metacarpo phalangeal (MP) joint, rotate the digit by about 120° for pulp to pulp pinch, palmarly abduct by 40-50° to get a new first web gap, Shorten and readjust the tension of the extensors, re attach the intrinsics to form a thenar eminence capable of positioning the new thumb in various functional positions and finally close the flaps forming a new skin envelope. The author has performed over 75 pollicisations personally and has personal experience of some of the issues raised there. The steps mentioned therefore are an algorithm for helping the uninitiated into these choppy waters. PMID:24501467

Spacelab Science Results Study  

NASA Technical Reports Server (NTRS)

Beginning with OSTA-1 in November 1981 and ending with Neurolab in March 1998, a total of 36 Shuttle missions carried various Spacelab components such as the Spacelab module, pallet, instrument pointing system, or mission peculiar experiment support structure. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the U.S., Europe, and Japan. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and if appropriate, where the knowledge they produced has been applied.

Physics Results from COMPASS  

E-print Network

The COMPASS Experiment at the CERN SPS has a broad physics program focused on the nucleon spin structure and on hadron spectroscopy, using muon and hadron beams. Main objectives for the spin program with the muon beam are the direct measurement of the gluon contribution to the spin of the nucleon, semi-inclusive measurements, and the measurement of the transverse spin distribution $\\Delta_T q$. The COMPASS apparatus consists of a two-stage large acceptance spectrometer designed for high data rates and equipped with high-resolution tracking, particle identification and electromagnetic and hadronic calorimetry. The data taking is ongoing since 2002 and till now was mainly devoted to the spin programme using a 160 GeV$/c$ naturally polarized, $\\mu^+$ beam and a polarized \\mrf{^6LiD} target. First physics results from the 2002 and 2003 runs are presented.

Multigan: First experimental results  

SciTech Connect

A new design of a multicharged ion source based on the MONO1000 ECRIS has been presented at the last ECR ion source (ECRIS) Workshop 2010. [L. Maunoury et al., in Proceedings of the XIXth International Workshop on ECR Ion Sources, Grenoble, France, 23-26 August 2010] This source has not only two opening at both ends but also a large space in the middle of the source enabling a direct contact with the ECR plasma. The source has been assembled mechanically and put on a test bench at the Pantechnik company. The primary tests have shown that the plasma ignition occurred at low pressure (10{sup -6} mbar) and low RF power (10 W). The first experimental results (= 1.30 for Ar and 1.85 for Xe) demonstrated the potential of this ion source in production of multicharged ion beams.

Top physics: CDF results  

SciTech Connect

The top quark plays an important role in the grand scheme of particle physics, and is also interesting on its own merits. We present recent results from CDF on top-quark physics based on 100-200 pb{sup -1} of p{bar p} collision data. We have measured the t{bar t} cross section in different decay modes using several different techniques, and are beginning our studies of top-quark properties. New analyses for this conference include a measurement of {sigma}{sub t{bar t}} in the lepton-plus-jets channel using a neural net to distinguish signal and background events, and measurements of top-quark branching fractions.

Initial Results from CALIPSO  

NASA Technical Reports Server (NTRS)

CALIPSO will carry the first polarization lidar in orbit, along with infrared and visible passive imagers, and will fly in formation as part of the Afternoon Constellation (A-train). The acquisition of observations which are simultaneous and coincident with observations from other instruments of the A-train will allow numerous synergies to be realized from combining CALIPSO observations with observations from other platforms. In particular, cloud observations from the CALIPSO lidar and the CloudSat radar will complement each other, together encompassing the variety of clouds found in the atmosphere, from thin cirrus to deep convective clouds. CALIPSO has been developed within the framework of a collaboration between NASA and CNES and is currently scheduled to launch, along with the CloudSat satellite, in spring 2006. This paper will present an overview of the CALIPSO mission, including initial results.

Results of patch tests  

SciTech Connect

The objectives of this work were to construct, install, and operate a patch testing unit on a hot gas stream at a coal-fired fluidized-bed boiler. A 2,000-hour patch test was conducted on ceramic disks of materials used in the fabrication of ceramic candles and ceramic cross-flow filters. The primary issues addressed in these tests were the long-term physical, thermal, and chemical stability of the ceramic materials; long-term pressure drop and filtration characteristics of the ceramic filters; potential for irreversible blinding of filter elements; and long-term performance and reliability of auxiliary hardware, such as the tube sheet and pulse-cleaning systems. Results on three samples, or patches, 10 cm in diameter are given.

Recent Results from Phobos  

NASA Astrophysics Data System (ADS)

The PHOBOS detector is one of four heavy ion experiments at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. In this paper we will review some of the results of PHOBOS from the data collected in p+p, d+Au and Au+Au collisions at nucleon-nucleon center-of-mass energies up to 200 GeV. Evidence is found of the formation of a very high energy density and highly interactive system, which can not be described in terms of hadrons, and has a relatively low baryon density. There is evidence that the system formed is thermalized to a certain degree. Scaling with the number of participants and extended longitudinal scaling behavior are also observed in distributions of produced charged particles.

Stochastic Inflation: New Results  

E-print Network

This is an old article which has never been posted for public use and which only appeard in a relatively hard-to-get Proceedings of the Sakharov Conference in Moscow (May, 1991). The subject of this article has received a lot of attention in last two years. Although we acknowledge that there has been a very big progress in the field of relating the spectrum of fluctuations to scalar field potentials of inflation models, which have outdated some of our results (particularly because we never took into account the tensor fluctuations which have been shown to be crucial for reconstructing the inflaton potential) we think that some of the other ideas and approaches which we presented in this article maybe still of interest. We did not rewrite the article to include any of the newer approaches and we did not add any of the newer references. The reader is advised to refer to recent papers (for example, see the paper astro-ph/9403001 by Edward Kolb and Sharon Vadas) for state of the art review and up-to-date references. ==The original abstract of the article==: We prove that, in stochastic approach, there exists an equivalence relation between different inflationary models under some redefinition of field and time variables. The postinflationary physics is insensitive to it and one can say that related theories are in fact indistinguishable from the viewpoint

Borexino latest results  

NASA Astrophysics Data System (ADS)

Borexino is a unique detector, able to measure neutrino interactions with a lower energy threshold down to ˜200 keV. This performance is allowed by an unprecedented radiopurity reached by means of a proper technology, developed in almost five year of R&D. Borexino succeeded to measure until now, and for the first time, the 7Be and pep solar neutrino fluxes, the 8B flux with a threshold down to 3. MeV, and reached a strict upper limit for the CNO neutrinos. In addition the day/night effect has been observed to be null for the 7Be flux. These achievements allowed to check for the first time the oscillation MSW-LMA model, presently adopted, in Vacuum and in the transition region, and offered the possibility to measure the ratio between the ve survival probabilities in vacuum and in matter. The results obtained by Borexino are compared to the previsions of the Solar Standard Model. The Borexino further goal is to study also the pp neutrino flux and to reduce the total error on the pep and 8B measurements, and therefore to allow a check of the hypothesis of Non Standard Neutrino Interactions. Borexino reached also evidence of the geo-neutrinos with 4.2 ? confidence level.

Results from SNO  

SciTech Connect

The Sudbury Neutrino Observatory (SNO) is an underground heavy water Cherenkov detector for studying solar neutrinos. SNO is capable of performing both flavor sensitive and flavor blind measurements of the solar neutrino flux. The first charged current (CC) measurement is found to be: {psi}{sub SNO}{sup CC}({nu}{sub e}) = 1.75 {+-} 0.07(stat.){sub -0.11}{sup +0.12}(sys.) {+-} 0.05 (theor.) x 10{sup 6} cm{sup -2}s{sup -1} and the elastic scattering fluxes (ES) is: {psi}{sub SNO}{sup ES}({nu}{sub x}) = 2.39 {+-} 0.34(stat.){sub -0.14}{sup +0.16} (sys.) x 10{sup 6} cm{sup -2}s{sup -1}. The {psi}{sub SNO}{sup CC}({nu}{sub e}) result, when combined with the high statistics elastic scattering (ES) measurement from Super-Kamiokande, provide a strong evidence for solar neutrino flavor transformation (3.3{sigma}). The deduced total solar neutrino flux is in good agreement with standard solar model predictions. No significant distortion in the energy spectrum is observed.

Sudbury Neutrino Observatory Results  

E-print Network

The Sudbury Neutrino Observatory uses 1000 tonnes of heavy water in an ultra-clean Cherenkov detector situated 2 km underground in Ontario, Canada to study neutrinos from the Sun and other astrophysical sources. The Charged Current (CC) reaction on deuterium is sensitive only to electron neutrinos whereas the Neutral Current (NC) is equally sensitive to all active neutrino types. By measuring the flux of neutrinos from 8B decay in the Sun with the CC and NC reactions it has been possible to establish clearly, through an appearance measurement, that electron neutrinos change to other active neutrino types, properties that are beyond the Standard Model of elementary particles. The observed total flux of active neutrinos agrees well with solar model flux calculations for 8B. This provides a clear answer to the "Solar Neutrino Problem". When these results are combined with other measurements, the oscillation of massive neutrinos is strongly defined as the primary mechanism for flavor change and oscillation parameters are well constrained.

Results from Venus Express  

NASA Astrophysics Data System (ADS)

Venus Express has been in orbit around Venus since May 2006 and has since then delivered a large amount of new and unique information on our sister planet. The atmosphere has been mapped in three dimensions and at regular intervals time lapse movies have been generated in order to make detailed characterization of the circulation patterns at different altitudes. The thermal structure has been investigated with several different but complementary techniques to cover the range between 40km and 140 km. The surface temperature has been mapped over a large part of the southern hemisphere and regions with anomalous emissivity have been studied in some detail. The chemical analysis has characterised a large number of species and detected for the first time the radical hydroxyl. Existence of frequent lightning has been inferred from whistler waves detected by the magnetometer. Escape rates of hydrogen, oxygen and helium have been estimated. Recently the pericentre altitude was reduced to 185 km in order to better characterize, in situ, the magnetic fields and energetic particle environment. This talk will provide a summary of the most important results and give a status update of the mission.

Simpler images, better results  

NASA Astrophysics Data System (ADS)

The very rapid development of optical technology has followed a pattern similar to that of nuclear magnetic resonance: first, spectroscopy and then imaging. The accomplishments in spectroscopy have been significant--among them, early detection of hematomas and quantitative oximetry (assuming that time and frequency domain instruments are used). Imaging has progressed somewhat later. The first images were obtained in Japan and USA a few years ago, particularly of parietal stimulation of the human brain. Since then, rapid applications to breast and limb, together with higher resolution of the brain now make NIR imaging of functional activation and tumor detection readily available, reliable and affordable devices. The lecture has to do with the applications of imaging to these three areas, particularly to prefrontal imaging of cognitive function, of breast tumor detection, and of localized muscle activation in exercise. The imaging resolution achievable in functional activation appears to be FWHM of 4 mm. The time required for an image is a few seconds or even much less. Breast image detection at 50 microsecond(s) ec/pixel results in images obtainable in a few seconds or shorter times (bandwidths of the kHz are available). Finally, imaging of the body organs is under study in this laboratory, particularly in the in utero fetus. It appears that the photon migration theory now leads to the development of a wide number of images for human subject tissue spectroscopy and imaging.

Climax granite test results  

SciTech Connect

The Lawrence Livermore Laboratory (LLL), as part of the Nevada Nuclear Waste Storage Investigations (NNWSI) program, is carrying out in situ rock mechanics testing in the Climax granitic stock at the Nevada Test Site (NTS). This summary addresses only those field data taken to date that address thermomechanical modeling for a hard-rock repository. The results to be discussed include thermal measurements in a heater test that was conducted from October 1977 through July 1978, and stress and displacement measurements made during and after excavation of the canister storage drift for the Spent Fuel Test (SFT) in the Climax granite. Associated laboratory and field measurements are summarized. The rock temperature for a given applied heat load at a point in time and space can be adequately modeled with simple analytic calculations involving superposition and integration of numerous point source solutions. The input, for locations beyond about a meter from the source, can be a constant thermal conductivity and diffusivity. The value of thermal conductivity required to match the field data is as much as 25% different from laboratory-measured values. Therefore, unless we come to understand the mechanisms for this difference, a simple in situ test will be required to obtain a value for final repository design. Some sensitivity calculations have shown that the temperature field is about ten times more sensitive to conductivity than to diffusivity under the test conditions. The orthogonal array was designed to detect anisotropy. After considering all error sources, anisotropic efforts in the thermal field were less than 5 to 10%.

Overview of JET results  

NASA Astrophysics Data System (ADS)

Since the last IAEA conference, the scientific programme of JET has focused on the qualification of the integrated operating scenarios for ITER and on physics issues essential for the consolidation of design choices and the efficient exploitation of ITER. Particular attention has been given to the characterization of the edge plasma, pedestal energy and edge localized modes (ELMs), and their impact on plasma facing components (PFCs). Various ELM mitigation techniques have been assessed for all ITER operating scenarios using active methods such as resonant magnetic field perturbation, rapid variation of the radial field and pellet pacing. In particular, the amplitude and frequency of type I ELMs have been actively controlled over a wide parameter range (q95 = 3-4.8, ?N <= 3.0) by adjusting the amplitude of the n = 1 external perturbation field induced by error field correction coils. The study of disruption induced heat loads on PFCs has taken advantage of a new wide-angle viewing infrared system and a fast bolometer to provide a detailed account of time, localization and form of the energy deposition. Specific ITER-relevant studies have used the unique JET capability of varying the toroidal field (TF) ripple from its normal low value ?BT = 0.08% up to ?BT = 1% to study the effect of TF ripple on high confinement-mode plasmas. The results suggest that ?BT < 0.5% is required on ITER to maintain adequate confinement to allow QDT = 10 at full field. Physics issues of direct relevance to ITER include heat and toroidal momentum transport, with experiments using power modulation to decouple power input and torque to achieve first experimental evidence of inward momentum pinch in JET and determine the threshold for ion temperature gradient driven modes. Within the longer term JET programme in support of ITER, activities aiming at the modification of the JET first wall and divertor and the upgrade of the neutral beam and plasma control systems are being conducted. The procurement of all components will be completed by 2009 with the shutdown for the installation of the beryllium wall and tungsten divertor extending from summer 2009 to summer 2010.

Mars Pathfinder Preliminary Results  

NASA Astrophysics Data System (ADS)

Pathfinder plays a key role as the first of the Surveyor series and as the first Discovery project to complete its mission. On July 4 the Pathfinder lands at Ares Vallis chosen as a grab-bag sample of small rocks washed down from the highland regions by the ancient catastrophic floods that once inundated the region. A multi-spectral, stereoscopic camera (IMP) was selected with the capability to discriminate rock types according to their spectral signatures between 0.4 and 1.1 microns. This range gives information on the iron mineralogies (the weathering of ferrous to ferric minerals) and some compositional information with the 0.9 micron pyroxene band. Stereo rangefinding allows contour-mapping of the surface, calculation of rock sizes, and helps with rover guidance. Operationally the camera data determines which rocks seem spectrally interesting and the stereo images allow the rover team to station the APXS against the rock for a night-long integration. The resulting data constrains the elemental composition which is then combined with the spectral data to determine the mineralogy of the rock. The study of the atmosphere is also a prime scientific goal. The ASI/MET team has instruments for measuring diurnal temperature and pressure variations as well as wind velocity. During the descent they also derive the vertical profiles of the atmosphere. IMP has three windsocks that are monitored hourly for wind signatures; looking at all three simultaneously gives the vertical wind gradient. IMP also has 8 atmospheric filters that allow the camera to image the sun directly and measure the opacity variations hourly throughout the day. At night, bright star and Phobos observations with the geology filters continue the characterization. Besides the dust opacity, three filters in the 0.94 micron water band are able to measure water vapor at large airmass factors. Finally, a series of magnets at various positions on the lander will show indications of the magnetic properties of windblown dust. This scientific station could last as long as an earth year on Mars; therefore, seasonal changes in the weather and surface can be tracked.

Reversible detection of heparin and other polyanions by pulsed chronopotentiometric polymer membrane electrode.  

PubMed

The first fully reversible polymeric membrane-based sensor for the anticoagulant heparin and other polyanions using a pulsed chronopotentiometry (pulstrode) measurement mode is reported. Polymeric membranes containing a lipophilic inert salt of the form R(+)R(-) (where R(+) and R(-) are tridodecylmethylammonium (TDMA(+)) and dinonylnaphthalene sulfonate (DNNS(-)), respectively) are used to suppress unwanted spontaneous ion extractions under zero-current equilibrium conditions. An anodic galvanostatic current pulse applied across the membrane perturbs the equilibrium lipophilic ion distribution within the membrane phase in such a way that anions/polyanions are extracted into the membrane from the sample. The membrane is then subjected to an open-circuit zero current state for a short period, and finally a 0 V vs reference electrode potentiostatic pulse is applied to restore the membrane to its initial full equilibrium condition. Potentials are sampled as average values during the last 10% of the 0.5 s open circuit phase of the measurement cycle. Fully reversible and reproducible electromotive force (emf) responses are observed for heparin, pentosan polysulfate (PPS), chondroitin sulfate (CS), and oversulfated chondroitin sulfate (OSCS), with the magnitude of the potentiometric response proportional to charge density of the polyanions. The sensor provides an emf response related to heparin concentrations in the range of 1-20 U/mL. The responses to variations in heparin levels and toward other polyanions of the pulstrode configuration are analogous to the already established single-use, nonreversible potentiometric polyion sensors based on membranes doped only with the lipophilic anion exchanger TDMA(+).

Overview of MAST results  

NASA Astrophysics Data System (ADS)

Significant progress has been made on the Mega Ampere Spherical Tokamak (MAST) towards a fundamental understanding of transport, stability and edge physics and addressing technological issues for future large devices. Collaborative studies of the L-H transition with NSTX and ASDEX Upgrade confirm that operation in a connected double-null configuration significantly reduces the threshold power, Pthr. The MAST data provide support for a theory for the transition based on finite ? drift wave turbulence suppression by self-generated zonal flows. Analysis of low and high field side density gradients in the H-mode pedestal provides support for an analytical model of the density pedestal width dependent on the neutral penetration depth. Adding MAST data to international confinement databases has enhanced confidence in scalings for ITER by significantly expanding the range of ? and ? explored and indicates a slightly stronger ? dependence than in current scalings. Studies of core transport have been conducted for well-diagnosed L-mode, H-mode and internal transport barrier (ITB) discharges using TRANSP, and microstability and turbulence studies have been carried out using GS2. Linear micro-stability analysis indicates that ITG modes are typically unstable on all flux surfaces with growth rates that are comparable to the equilibrium E × B flow shearing rate. Mixing length estimates of transport coefficients from ITG (neglecting flow shear) give diffusion coefficients that are broadly comparable with observed thermal diffusivities. Non-linear, collisionless ETG calculations have been performed and suggest radially extended electrostatic streamers up to 100?e across in radius. Transport from ITG could easily be suppressed in regions where the E × B shear flow rate, ?SE, exceeds the ITG growth rate, possibly contributing to ITBs. Toroidal rotation, driven by neutral beam torque, is the dominant contribution to ?SE via the vphiB? term in the radial electric field. Early edge localized mode activity on MAST is associated with the formation of narrow filamentary structures following field lines in the edge. These filaments rotate toroidally with the edge plasma and, away from the X-points, accelerate radially outwards from the edge up to 20 cm. Studies of disruptions on MAST demonstrate a complex evolution of core energy loss and resultant divertor power loads, including phases where the target heat flux width is broadened by a factor of 8. Observations of energetic particle modes driven by super-Alfvénic beam ions provide support for a model for the non-linear evolution of toroidal Alfvén eigenmodes (AEs) forming Bernstein-Green-Krushal waves. The AE activity reduces to low levels with increasing ?. Plasma start-up without a central solenoid and in a manner compatible with future large spherical tokamak (ST) devices has been demonstrated using breakdown at a quadrupole magnetic null. Closed flux surface plasmas with peak plasma currents up to 370 kA have been generated and sustained for 0.3 s. New error field correction coils have extended the operational space for low density plasmas and enabled scaling studies of error field induced locked mode formation in the ST.

Microsoft Academic Search

Pentosans are hydrolyzed to pentoses by dilute mineral acid hydrolysis. The main source of pentosans is hemicelluloses. Furfural can be produced by the acid hydrolysis of pentosan from fruit shells such as hazelnut, sunflower, walnut, and almond of agricultural wastes. Further dehydration reactions of the pentoses yield furfural. The hydrolysis of each shell sample was carried out in dilute sulfuric

ELECTRON DETACHMENT DISSOCIATION OF GLYCOSAMINOGLYCAN TETRASACCHARIDES  

PubMed Central

The first application of electron detachment dissociation (EDD) to carbohydrates is presented. The structural characterization of glycosaminoglycan (GAG) oligosaccharides by mass spectrometry is a longstanding problem, because of the lability of these acidic, polysulfated carbohydrates. Doubly-charged negative ions of four GAG tetrasaccharides are examined by EDD, collisionally activated dissociation (CAD), and infrared multiphoton dissociation (IRMPD). EDD is found to produce information-rich mass spectra with both cross ring and glycosidic cleavage product ions. In contrast, most of the product ions produced by CAD and IRMPD result from glycosidic cleavage. EDD shows great potential as a tool for locating the sites of sulfation and other modifications in glycosaminoglycan oligosaccharides. PMID:17074503

PHENIX recent heavy flavor results  

NASA Astrophysics Data System (ADS)

Cold nuclear matter (CNM) effects provide an important ingredient to interpret the results from heavy-ion collisions. Such effects include nuclear shadowing, intrinsic parton transverse momentum broadening, and initial patron energy loss. The measurement of heavy quark production is a good probe to study the CNM effects particularly on gluons, since heavy quarks are mainly produced via gluon fusions at RHIC energy. The PHENIX experiment has an ability to study the CNM effects by measuring leptons from heavy-flavor decay in a broad kinematic range. Comparisons of the results measured in different rapidity regions allow us to study modification of gluon density function in the Au nucleus depending on parton fractional momentum x. In addition, comparisons to the results from heavy-ion collisions (Au + Au and Cu + Cu) measured by PHENIX provide an insight into the role of CNM effects in such collisions. Recent PHENIX results on heavy quark production are discussed in this presentation.

New results from FRECOPA analysis  

NASA Technical Reports Server (NTRS)

New results from the ongoing analysis of the FRECOPA's (FREnch COoperative PAssive payload) system hardware are discussed. FRECOPA (AO138) was one of the 57 experiments flown on the LDEF satellite. The experiment was located on the trailing edge (Tray B3) and was exposed to UV radiation (11,100 equivalent sun hours), approximately equal to 34,000 thermal cycles, higher vacuum levels than the leading edge, a low atomic oxygen flux, and minor doses of protons and electrons. Due to LDEF's extended mission (5.8 years), CNES decided to set up a team to analyze the FRECOPA system. Initial results were presented at the First Post-Retrieval Conference, June, 1991. The results obtained since then are summarized.

Results from PHENIX at RHIC  

E-print Network

Results from PHENIX at RHIC in p-p and Au+Au collisions are presented from the perspective of measurements in p-p collisions at the CERN ISR which serve as a basis for many of the techniques used. Notable results include the equality of the suppression of inclusive pi0 and direct electrons (from the decay of heavy quarks) in the range of transverse momentuum 4 < pT < 9 GeV/c in central Au+Au collisions. This result appears to strongly disfavor the explanation of suppression as due to radiative energy loss of partons traversing a Quark Gluon Plasma but opens up a fundamental discussion of how Fermions get mass, whether all six quarks are nearly massless in a QGP and how to test this.

New Results on R Aquarii  

E-print Network

The first results on new optical data for R Aquarii (based on observations obtained with the 2.5m INT, the 2.5m NOT and the 3.5m NTT) are presented. The morphology and kinematics of the nebula, based on data obtained with the NTT from 1991 to 2000, are discussed. Physical parameters of the outer nebula and the knotty jet are derived using spectra obtained with the INT in 2001. From the analysis of all these data we propose that the spectacular knotty inner structure of R Aqr could result from the interaction of a highly collimated pulsating young jet with the older hourglass inner nebula.

First results from SAGE II  

SciTech Connect

The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first five runs of SAGE II give a capture rate of 76{sub {minus}18}{sup +21} (stat) {sub {minus}7}{sup +5} (sys) SNU. combined with the SAGE I result, the capture rate is 74{sub {minus}12}{sup +13} (stat) {sub {minus}7}{sup +5} (sys) SNU. This represents only 56%--60% of the capture rate predicted by different Standard Solar Models.

LISA Optics Model: Early Results  

NASA Technical Reports Server (NTRS)

The Laser Interferometer Space Antenna (LISA) optics model is used to generate a synthetic data stream in the absence of gravitational waves. The simulation has the spacecraft in moving in their respective Keplerian orbits. The pointing of the spacecraft and station keeping about the proof masses is accomplished using a control scheme, which minimizes the disturbance on the proof masses in the sensitive direction. The resulting data stream gives an indication of the magnitude of instrumental noise due to pointing jitter and motions of the spacecraft with respect to the proof masses. Computational details are presented and the results discussed.

Planck 2013 results. I. Overview of products and scientific results  

NASA Astrophysics Data System (ADS)

The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky continuously since 12 August 2009. In March 2013, ESA and the Planck Collaboration released the initial cosmology products based on the first 15.5 months of Planck data, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the mission and its performance, the processing, analysis, and characteristics of the data, the scientific results, and the science data products and papers in the release. The science products include maps of the cosmic microwave background (CMB) and diffuse extragalactic foregrounds, a catalogue of compact Galactic and extragalactic sources, and a list of sources detected through the Sunyaev-Zeldovich effect. The likelihood code used to assess cosmological models against the Planck data and a lensing likelihood are described. Scientific results include robust support for the standard six-parameter ?CDM model of cosmology and improved measurements of its parameters, including a highly significant deviation from scale invariance of the primordial power spectrum. The Planck values for these parameters and others derived from them are significantly different from those previously determined. Several large-scale anomalies in the temperature distribution of the CMB, first detected by WMAP, are confirmed with higher confidence. Planck sets new limits on the number and mass of neutrinos, and has measured gravitational lensing of CMB anisotropies at greater than 25?. Planck finds no evidence for non-Gaussianity in the CMB. Planck's results agree well with results from the measurements of baryon acoustic oscillations. Planck finds a lower Hubble constant than found in some more local measures. Some tension is also present between the amplitude of matter fluctuations (?8) derived from CMB data and that derived from Sunyaev-Zeldovich data. The Planck and WMAP power spectra are offset from each other by an average level of about 2% around the first acoustic peak. Analysis of Planck polarization data is not yet mature, therefore polarization results are not released, although the robust detection of E-mode polarization around CMB hot and cold spots is shown graphically.

The Planck Mission: Early Results  

SciTech Connect

The ESA Planck space mission, launched on May 14, 2009, is dedicated to high precision measurements of the cosmic microwave background (CMB), the first light of the universe, both in temperature and polarization. The satellite observes the full sky from a far-Earth orbit with two cryogenic instruments in the 30-850 GHz range at the focal plane of a 1.5-meter telescope. The primary objective of Planck is to measure with unprecedented precision the key cosmological parameters and to provide accurate tests of physics in the early universe. Planck has recently completed the fifth full-sky survey. The data analysis is underway. The first cosmology results are expected in early 2013 while a number of astrophysical results have been recently delivered to the community, including galactic and extragalactic astrophysics and a rich catalogue of radio and infrared sources. These results demonstrate the excellent in-orbit performance of the instruments and give excellent prospects for the forthcoming cosmological results.

Overview of ASDEX Upgrade results  

Microsoft Academic Search

Recent results from the ASDEX Upgrade experimental campaigns 2001 and 2002 are presented. An improved understanding of energy and particle transport emerges in terms of a 'critical gradient' model for the temperature gradients. Coupling this to particle diffusion explains most of the observed behaviour of the density profiles, in particular, the finding that strong central heating reduces the tendency for

Support for exploratory interaction with databases in applications such as data mining requires that the first few results of an operation be available as quickly as possible. We study the algorithmic side of what can and what cannot be achieved for processing join operations. We develop strategies that modify the strict two-phase processing of the sort-merge paradigm, intermingling join steps

Top physics results from CDF  

SciTech Connect

The top quark is by far the most massive fundamental particle observed so far, and the study of its properties is interesting for several reasons ranging from its possible special role in electroweak symmetry breaking to its sensitivity to physics beyond the Standard Model. They present recent top physics results from CDF based on 160-320 pb{sup -1} of p{bar p} collision data at {radical}s = 1.96 TeV. The t{bar t} cross section and the top mass have been measured in different decay channels and using different methods. they have searched for evidence of single top production, setting upper limits on its production rate. Other results shown in this conference include studies of the polarization of W bosons from top decays, a search for charged Higgs decaying from top, and a search for additional heavy t' quarks.

Overview of Results from MAST  

NASA Astrophysics Data System (ADS)

We present results from the diverse MAST experimental programme. Features include transport analysis of discharges with edge or internal transport barriers, and high confinement discharges, with and without ITBs, under counter-current NBI. H mode studies are extended to include confinement measurements for submission to the ITER database, as well as controlled experiments on the L/H transition to cast light on the transition process. An important aspect of exhaust studies on MAST is the measurement and control of transient and steady-state power loads, and ELMs are analysed in terms of both their dynamic structure and their impact on the first wall. During 2003-4 MAST has undergone significant enhancement including new divertors to handle increased NBI power and pulse length, error field correction coils to extend the operating space towards lower density and q, a new CXRS system and a new HFS gas injection system. Early results exploiting these new facilities are also presented.

[Colpocleisis: indications, technique and results].  

PubMed

The aim of this review was to summarize recent published data about indications, surgical technique and results of colpocleisis. We conducted a literature search on Medline using PubMed from 1990 to 2008. Anatomical and functional results were assessed for each selected study according to the age and the morbidity of the surgical procedure. As the colpocleisis was complete or partial, anatomic success rates were reported near 100 % with a follow-up ranged from one month to six years. Colpocleisis is an effective procedure for treatment of advanced pelvic organ prolapse in selected patient who no longer desire preservation of coital function. Concomitant anti-incontinence procedure is not associated with increased postoperative morbidity. However, preoperative urodynamics remain to be established for an optimal management of urinary incontinence. PMID:19969275

PHENIX recent heavy flavor results  

E-print Network

Cold nuclear matter (CNM) effects provide an important baseline for the interpretation of data in heavy ion collisions. Such effects include nuclear shadowing, Cronin effect, and initial patron energy loss, and it is interesting to study the dependence on impact parameter and kinematic region. Heavy quark production is a good measurement to probe the CNM effects particularly on gluons, since heavy quarks are mainly produced via gluon fusions at RHIC energy. The PHENIX experiment has experiment has ability to study the CNM effects by measuring heavy quark production in $d$$+$Au collisions at variety of kinematic ranges. Comparisons of heavy quark production at different rapidities allow us to study modification of gluon density function in the Au nucleus depending on momentum fraction. Furthermore, comparisons to the results from heavy ion collisions (Au$+$Au and Cu$+$Cu) measured by PHENIX provide insight into the role of CNM effects in such collisions. Recent PHENIX results on heavy quark production are discussed.

Ionization model results of ionocraft  

E-print Network

An ionocraft is a small instrument that generates net vertical force from electrostatic field. A model of ionization and flow is built to explain this force. The assumption of a threshold field density and the constant charge density is applied to simplify the flow model. With these assumptions, corresponding simulation results and comparison with experimental data, we have shown that this model is sufficient to explain the force on the ionocraft.

The WMAP data and results  

NASA Astrophysics Data System (ADS)

The Wilkinson Microwave Anisotropy Probe (WMAP) science team has released results from the first year of operation at the Earth-Sun L 2 Lagrange point. The maps are consistent with previous observations but have much better sensitivity and angular resolution than the COBE DMR maps, and much better calibration accuracy and sky coverage than ground-based and balloon-borne experiments. The angular power spectra from these ground-based and balloon-borne experiments are consistent within their systematic and statistical uncertainties with the WMAP results. WMAP detected the large angular-scale correlation between the temperature and polarization anisotropies of the CMB caused by electron scattering since the Universe became reionized after the "Dark Ages", giving a value for the electron scattering optical depth of 0.17 ± 0.04. The simplest ?CDM model with n=1 and ? tot=1 fixed provides an adequate fit to the WMAP data and gives parameters which are consistent with determinations of the Hubble constant and observations of the accelerating Universe using supernovae. The time-ordered data, maps, and power spectra from WMAP can be found at http://lambda.gsfc.nasa.gov along with 13 papers by the WMAP science team describing the results in detail.

ISO: highlights of recent results  

NASA Astrophysics Data System (ADS)

ESA's Infrared Space Observatory (ISO) mission, operating in the wavelength range from 2.5 to 240 microns, made over 26000 scientific observations during its 2.5 year operational lifetime. ISO's results broke new ground on all scales. New asteroid counts and improved asteroid thermophysical models augmented important advances in Solar System chemistry to comprise a striking body of results addressing our planetary system. In turn, parallels between the chemical composition of Solar System dust and dust around other stars revealed by the comparison of stellar spectra with cometary spectra, together with results on the incidence and stability of stellar disks, recall the birth of our Solar System and point to fundamental similarities with other star systems. Numerous important facts concerning the chemistry of the ISM have unfolded, such as the ubiquity of water and of the probably-organic carriers of the Unidentified Infrared Bands (UIBs). The large systematic body of data on galactic stars has permitted fascinating advances in the characterisation of important aspects of stellar evolution. Investigations of nearby normal galaxies complement template specimens of interacting galaxies. These in turn exemplify galaxy evolutionary processes in the early Universe associated with a huge burst of dust-obscured star formation at redshifts of just below one. This global surge of star formation has vital implications for the interpretation and explanation of major components of the Extragalactic Background Light (EBL) and for charting the global history of star formation and the relative importance of sources which derive their energy from accretion processes. Representative examples of key aspects of ISO's recent scientific output will be presented, once again affirming ISO's place at the forefront of successful space-borne astronomy missions.

After more than 20 years of continuous work and several months of commissioning with cosmic muon data, the ATLAS experiment started data taking at the Large Hadron Collider (CERN). From November 2009 to May 2010, ATLAS registered proton-proton collisions at 900 GeV, 2.36 GeV and finally 7 TeV center of mass energy. These data samples have been used to study the detector performance in detail and are currently being used also for the first physics studies. In this document, we present some selected physics and performance results obtained with the first 7 TeV proton-proton collisions.

Hadron production is a key ingredient in many aspects of {nu} physics. Precise prediction of atmospheric {nu} fluxes, characterization of accelerator {nu} beams, quantification of {pi} production and capture for {nu}-factory designs, all of these would profit from hadron production measurements. HARP at the CERN PS was the first hadron production experiment designed on purpose to match all these requirements. It combines a large, full phase space acceptance with low systematic errors and high statistics. HARP was operated in the range from 3 GeV to 15 GeV. We briefly describe here the most recent results.

On July 4th both ATLAS and CMS announced the observation of a new particle in the search for the Higgs boson. The required sensitivity above 5 sigma could only be achieved by combining different search channels and by analysing both the data from 2011 and 2012. Several production and decay modes can shed light on the properties of this new particle, but the full picture can only be obtained by combining all the available information. This talk will provide an overview over the complementary measurements used as input for the latest combination at ATLAS and its results both in terms of signal strength and properties.

Long Trace Profiler survey results

Today the Long Trace Profiler (LTP) is widely accepted as a viable way to measure X-ray mirrors, and at some institutions is the only instrument available for measuring long, high-curvature aspheres. Although some questions of absolute accuracy over the entire LTP measurement range remain unanswered, a comparison of LTPs can still be made to assess measurement variation. Recently a round robin survey of some LTPs within the United States has been made using a single set of mirrors. These mirrors were used to characterize the performance of an LTP over its advertised range of operation. The results of this survey are presented here.

Some results about Schiffer's conjectures  

NASA Astrophysics Data System (ADS)

We study two overdetermined problems in spectral theory, about the Laplace operator. These problems are known as Schiffer's conjectures and are related to the Pompeiu problem. We show the connection between these problems and the critical points of the functional eigenvalue with a volume constraint. We use this fact, together with the continuous Steiner symmetrization, to give another proof of Serrin's result for the first Dirichlet eigenvalue. In two dimensions and for a general simple eigenvalue, we obtain different integral identities and a new overdetermined boundary value problem.

Unfavourable results in thumb reconstruction  

PubMed Central

The history of thumb reconstruction parallels the history of hand surgery. The attributes that make the thumb unique, and that the reconstructive surgeon must assess and try to restore when reconstructing a thumb, are: Position, stability, strength, length, motion, sensibility and appearance. Deficiency in any of these attributes can reduce the utility of the reconstructed thumb. A detailed assessment of the patient and his requirements needs to be performed before embarking on a thumb reconstruction. Most unsatisfactory results can be attributed to wrong choice of procedure. Component defects of the thumb are commonly treated by tissue from adjacent fingers, hand or forearm. With refinements in microsurgery, the foot has become a major source of tissue for component replacement in the thumb. Bone lengthening, osteoplastic reconstruction, pollicisation, and toe to hand transfers are the commonest methods of thumb reconstruction. Unfavourable results can be classified as functional and aesthetic. Some are common to all types of procedures. However each type of reconstruction has its own unique set of problems. Meticulous planning and execution is essential to give an aesthetic and functionally useful thumb. Secondary surgeries like tendon transfers, bone grafting, debulking, arthrodesis, may be required to correct deficiencies in the reconstruction. Attention needs to be paid to the donor site as well.

New Results on Cepheid Masses  

NASA Astrophysics Data System (ADS)

Masses for Cepheid variable stars can be measured by combining the orbital velocity amplitude for the Cepheid (from a ground-based orbit) with the orbital velocity amplitude of a hot main sequence companion (observed in the ultraviolet from satellites such as IUE and HST) and the mass of the companion (inferred from from the ultraviolet energy distribution). Observations of 5 binary systems are now completed or in progress with the Goddard High Resolution Spectrograph on the Hubble Space Telescope. Recently completed observations of U Aql lead to a mass of 5.1 +/- 1.1 Msun . We will discuss the results for S Mus, V350 Sgr, U Aql, and Y Car, and the constraints they place on stellar evolution calculations. As would be expected, some of the B companions have high rotational velocities, decreasing the accuracy with which their orbital velocities can be measured. The preliminary conclusion from the 4 HST targets and SU Cyg (mass from IUE observations) is that a weighted mean indicates no convective overshoot but the mode (which reflects the HST results better) agrees with the modest overshoot used in the Geneva evolutionary calculations. Financial Support was provided by a NASA grant GO-4541-01 to EB--V and GO-4541.02 to KGC, a grant from the Natural Sciences and Engineering Council, Canada to NRE, from the AXAF Science Center NASA Contract NAS8-39073.

TMX-U experimental results  

SciTech Connect

This paper describes results from the Tandem Mirror Experiment-Upgrade (TMX-U). Mirror-confined electrons with 30 to 70 keV mean energy densities of 0.5 to 2.0 x 10/sup 12/ cm/sup -3/ and average betas of 3 to 5% are produced using electron-cyclotron resonant heating (ECRH). These results are consistent with an electron Fokker-Planck code. Improved ion-cyclotron microstability is observed using neutral beam injection at 47/sup 0/ to the magnetic axis, rather than at 90/sup 0/ as in the previous experiment, TMX. Strong end plugging has been produced using a combination of ECRH gyrotrons with sloshing-ion beam injection. In these low-density central cell experiments (3 x 10/sup 11/ cm/sup -3/) the axial losses (tau/sub parallel/ = 20 to 80 ms) are smaller than the nonambipolar radial losses (tau/sub perpendicular/ = 4 to 8 ms). Plugging has been achieved with a central cell density double that of the end plugs. Although no direct measurements are yet available to determine if a thermal barrier potential dip is generated, these experiments support many theoretical features of the thermal barrier concept.

Mammographic mass classification: initial results  

NASA Astrophysics Data System (ADS)

Mammography is recognized as an important means to reduce breast cancer mortality. However, its accuracy is limited, both in sensitivity (some cancers are missed) and specificity (many non-cancer cases are referred for invasive procedures). It has been shown that computer classification of expert radiologist's findings can improve the specificity of mammography. Our project is aimed at automatically extracting measurements by computer analysis of digital mammograms, so as to provide automatic inputs for a benign/malignant classifier. We tested classification of radiological findings and found an area under the ROC curve of 0.95, comparable to what has been reported in the literature. Image measurements were taken from manual segmentations of lesions as well as from two different automatic segmentations. We found that segmentation using a fuzzy clustering method with some post-processing gives results comparable to results on manual outlines with a positive predictive value of 73%. The fuzzy clustering strategy has the potential to provide fully automatic classifications comparable to those based on expert radiological findings. This approach may dramatically reduce the false alarm rate currently seen in screening mammography.

AXAF hypervelocity impact test results  

NASA Technical Reports Server (NTRS)

Composite and honeycomb panels are commonly used for spacecraft structural components. The impact test results and analysis of six different composite and honeycomb combinations for use on the advanced X-ray astrophysics facility (AXAF) are reported. The AXAF consists of an X-ray telescope and the associated detecting devices attached to an octagonal spacecraft with an internal propulsion system. The spacecraft's structural panels and optical bench are made of two different graphite fiber reinforced polyimides or composite panels bonded to either side of an aluminum honeycomb. The instrument is required to have at least a 0.92 probability of no failure of any of the critical elements due to meteoroids and debris. In relation to the no-failure probability determination in its low earth orbit environment, hypervelocity impact testing was performed to determine the ballistic limit range and the extent of damage due to impact. The test results for a power and signal cable bundle located behind a panel are presented. Tests planned for a multilayer insulation (MLI) blanket and four types of cable bundles are discussed.

Current MINOS Neutrino Oscillation Results  

SciTech Connect

The MINOS experiment is now making precise measurements of the {nu}{sub {mu}} disappearance oscillations seen in atmospheric neutrinos, tests possible disappearance to sterile {nu} by measuring the neutral current flux, and has extended our reach towards the so far unseen {theta}{sub 13} by looking for {nu}{sub e} appearance in the {nu}{sub {mu}} beam. It does so by using the intense, well-understood NuMI neutrino beam created at Fermilab and observing it 735km away at the Soudan Mine in Northeast Minnesota. High-statistics studies of the neutrino interactions themselves and the cosmic rays seen by the MINOS detectors have also been made. Results from MINOS first three years of operations will be presented.

Clinical results of patellofemoral arthroplasty.  

PubMed

Isolated patellofemoral arthritis can be a disabling condition that can be challenging to treat. Patients with symptoms recalcitrant to conservative measures are considered for total or partial knee arthroplasty. This retrospective study reports the results of patellofemoral arthroplasty at a single center using a variety of implant designs. Thirty patients (37 knees) with isolated patellofemoral disease treated with patellofemoral arthroplasty with a minimum of one year follow-up were evaluated. The majority of patients were female (83%) and the underlying diagnosis was osteoarthritis in 98% of knees. Reported follow-up averaged 31 months. Average Knee Society Pain, Functional, and Clinical Scores improved from pre-op to most recent follow-up. Two complications (5.4%) required intervention. One patient was converted to a total knee arthroplasty secondary to patella instability. PMID:23790605

Initial Blackbeard power survey results  

SciTech Connect

The Blackbeard broadband VHF radio receiver is in low-earth orbit aboard the ALEXIS satellite. The receiver has been used to measure the transmitted power in four VHF bands (55.2-75.8, 28.0-94.8, 132.3-152.2, and 107.7-166.0 MHz) over quiet and noisy parts of the earth. The authors present the results of the survey and discuss their implications. They find that there are remote ocean areas over which the observed spectrum is largely free of man-made interference, but that the spectrum over most of the earth is dominated by broadcast VHF signals. The signal characteristics observed over a given area are quite constant when observed at different times of day and at intervals of several weeks to months. It appears that in many cases the bulk of the signal power is coming from a small number of sources.

Recent results from Telescope Array  

E-print Network

The Telescope Array (TA) observatory, located in midwest Utah, USA, is designed to detect ultra high energy cosmic rays whose energy is greater than 1 EeV. TA mainly consists of two types of detector. The first type is the atmospheric Fluorescence Detector (FD). TA's three FDs have been in operation since Fall 2007. The other type of detector is a ground-covering Surface Detector (SD), which has been operating at TA since Spring 2008. In addition, the TA-Rader (TARA) and EUSO-TA associated experiments are co-located with TA, and the TA Low Energy (TALE) extension recently started partial operation. I report some recent general results from TA, and describe our future plans.

Results of the ACCESS experiment  

NASA Technical Reports Server (NTRS)

All basic EVA space construction tasks included in the experiment were accomplished on-orbit successfully, and the construction task time shows good correlation with neutral buoyancy data. However, the flight assembly times were slightly longer than the best times obtained in the water tank. This result was attributed by the EVA astronauts to the new, tighter tolerance truss hardware used on-orbit as opposed to the well-worn training hardware used in the neutral buoyancy and was, thus, not a space related phenomenon. The baseline experiment demonstrated that erectable structure can be assembled effectively by astronauts in EVA. The success of ACCESS confirmed the feasibility of EVA space assembly of erectable trusses and played a role in the decision to baseline the Space Station as a 5 meter erectable structure.

New results on planetary lightning  

NASA Astrophysics Data System (ADS)

We present the latest observations from spacecraft and ground-based instruments in search for lightning activity in the atmospheres of planets in the solar system, and put them in context of previous research. Since the comprehensive book on planetary atmospheric electricity compiled by Leblanc et al. (2008), advances in remote sensing technology and telescopic optics enable detection of additional and new electromagnetic and optical emissions, respectively. Orbiting spacecraft such as Mars Express, Venus Express and Cassini yield new results, and we highlight the giant storm on Saturn of 2010/2011 that was probably the single most powerful thunderstorm ever observed in the solar system. We also describe theoretical models, laboratory spark experiments simulating conditions in planetary mixtures and map open issues.

NASA Astrophysics Data System (ADS)

The KASCADE-Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 1014-1018 eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 1016-1018 eV range by sampling charged (Nch) and muon (N?) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE-Grande to derive the mass composition of the measured high-energy comic rays is presented as well.

Monsoon '90 - Preliminary SAR results  

NASA Technical Reports Server (NTRS)

Multifrequency polarimetric synthetic aperture radar (SAR) images of the Walnut Gulch watershed near Tombstone, Arizona were acquired on 28 Mar. 1990 and on 1 Aug. 1990. Trihedral corner reflectors were deployed prior to both overflights to allow calibration of the two SAR data sets. During both overflights, gravimetric soil moisture and dielectric constant measurements were made. Detailed vegetation height, density, and water content measurements were made as part of the Monsoon 1990 Experiment. Preliminary results based on analysis of the multitemporal polarimetric SAR data are presented. Only the C-band data (5.7-cm wavelength) radar images show significant difference between Mar. and Aug., with the strongest difference observed in the HV images. Based on the radar data analysis and the in situ measurements, we conclude that these differences are mainly due to changes in the vegetation and not due to the soil moisture changes.

Data Assimilation Results from PLASMON  

NASA Astrophysics Data System (ADS)

VLF and magnetometer observations can be used to remotely sense the plasmasphere. VLF whistler waves can be used to measure the electron density and magnetic Field Line Resonance (FLR) measurements can be used to measure the mass density. In principle it is then possible to remotely map the plasmasphere with a network of ground-based stations which are also less expensive and more permanent than satellites. The PLASMON project, funded by the EU FP-7 program, is in the process of doing just this. A large number of ground-based observations will be input into a data assimilative framework which models the plasmasphere structure and dynamics. The data assimilation framework combines the Ensemble Kalman Filter with the Dynamic Global Core Plasma Model. In this presentation we will describe the plasmasphere model, the data assimilation approach that we have taken, PLASMON data and data assimilation results for specific events.

High Current Experiment: First Results  

NASA Astrophysics Data System (ADS)

The High Current Experiment (HCX) is being assembled at Lawrence Berkeley National Laboratory as part of the US program to explore heavy-ion beam transport at a scale representative of the low-energy end of an induction linac driver for fusion energy production. The primary mission of this experiment is to investigate aperture fill factors acceptable for the transport of space-charge dominated heavy-ion beams at high spacecharge intensity over long pulse durations. This machine will test transport issues at a driver-relevant scale resulting from nonlinear space-charge effects and collective modes, beam centroid alignment and beam steering, matching, image charges, halo, lost-particle induced electron effects, and longitudinal bunch control.

We present results from the CERN Axion Solar Telescope (CAST) and the Axion Dark Matter eXperiment (ADMX), together with a brief review on prospects on Axion searches with a variety of experimental techniques. CAST has explored masses up to 0.64 eV setting the most stringent limit on the axion-photon coupling, apart for the micro-eV region where ADMX is the most competitive experiment. CAST is aiming at surpassing the 1eV WMAP upper limit and possibly revisiting the operation in vacuum with extra sensitive X-ray detectors, while ADMX, using improved extra sensitive SQUID amplifiers will explore the micro-eV mass range.

SOFIS FTS EM test results  

NASA Astrophysics Data System (ADS)

The Solar Occultation FTS for Inclined-orbit Satellite (SOFIS) is a solar occultation Fourier transform spectrometer developed by the Ministry of the Environment (MOE) in Japan for the Global Change Observation Mission-A1 (GCOM-A1) satellite. GCOM-A1 will be placed in a 650 km non-sun-synchronous orbit, with an inclination angle of 69 degrees. ABB-Bomem is a sub-contractor of NTSpace (NEC-Toshiba Space) for the design and manufacturing of the FTS Engineering Model of SOFIS. SOFIS measures the vertical profile of the atmospheric constituents with 0.2 cm-1 spectral resolution for the spectral range covering 3-13 ?m. The atmospheric vertical resolution of SOFIS is 1 km. The target of SOFIS measurements is a global distribution of O3, HNO3, NO2, N2O, CH4, H2O, CO2, CFC-11, CFC-12, ClONO2, aerosol extinction, atmospheric pressure and temperature. NTSpace in Japan is the prime contractor of SOFIS. The spectrometer is an adapted version of the classical Michelson interferometer using an optimized optical layout and moving retro-reflectors. A solid-state laser diode operating at 1550 nm is used as metrology source of the interferometer. Its highly folded optical design results in a high performance instrument with a compact size. SOFIS FTS implements high performance control techniques to achieve outstanding speed stability of the moving mechanism. This paper describes the test activities of the SOFIS-FTS Engineering Model (EM) and preliminary results. The performances of the FTS are presented in terms of key parameters like signal-to-noise ratio, modulation efficiency and stability. Spectra acquired are shown and test methodology and analyses are presented. Lessons learned during assembly, integration and testing are described as well as improvements planned to be implemented in the Flight Model.

Comparative Soot Diagnostics: Preliminary Results  

NASA Technical Reports Server (NTRS)

The motivation for the Comparative Soot Diagnostics (CSD) experiment lies in the broad practical importance of understanding combustion generated particulate. Depending upon the circumstances, particulate matter can affect the durability and performance of combustion equipment, can be a pollutant, can be used to detect fires and, in the form of soot, can be the dominant source of radiant energy from flames. The nonbuoyant structure of most flames of practical interest makes understanding of soot processes in low gravity flames important to our ability to predict fire behavior on earth. These studies also have direct applications to fire safety in human-crew spacecraft, since smoke is the indicator used for automated detection in current spacecraft. In the earliest missions (Mercury, Gemini and Apollo), the crew quarters were so cramped that it was considered reasonable that the astronauts would rapidly detect any fire. The Skylab module, however, included approximately 20 UV-sensing fire detectors. The Space Shuttle has 9 particle-ionization smoke detectors in the mid-deck and flight deck and Spacelab has six additional particle-ionization smoke detectors. The designated detectors for the ISS are laser-diode, forward-scattering, smoke or particulate detectors. Current plans for the ISS call for two detectors in the open area of the module, and detectors in racks that have both cooling air flow and electrical power. Due to the complete absence of data concerning the nature of particulate and radiant emission from incipient and fully developed low-g fires, all three of these detector systems were designed based upon l-g test data and experience. As planned mission durations and complexity increase and the volume of spacecraft increases, the need for and importance of effective, crew-independent, fire detection grows significantly. To provide this level of protection, more knowledge is needed concerning low-gravity fire phenomena and, in particular, how they might be detected and suppressed. Prior to CSD, no combustion-generated particulate samples had been collected near the flame zone for well-developed microgravity flames. All of the extant data either came from drop tower tests and therefore only corresponded to the early stages of a fire or were collected far from the flame zone. The fuel sources in the drop tower tests were restricted to laminar gas-jet diffusion flames and very rapidly overheated wire insulation. The gas-jet tests indicated, through thermophoretic sampling, (2) that soot primaries and aggregates (groups of primary particles) in low-gravity may be significantly larger than those in normal gravity (1-g). This raises new scientific questions about soot processes as well as practical issues for particulate size sensitivity and detection alarm threshold levels used in on-orbit smoke detectors. Preliminary tests in the 2.2 second drop tower suggest that particulate generated by overheated wire insulation may be larger in low-g than in 1-g. Transmission Electron Microscope (TEM) grids downstream of the fire region in the Wire Insulation Flammability experiment as well as visual observation of long string-like aggregates, further confirm this suggestion. The combined impact of these limited results and theoretical predictions is that, as opposed to extrapolation from l-g data, direct knowledge of low-g combustion particulate is needed for more confident design of smoke detectors for spacecraft. This paper describes the operation and preliminary results of the CSD, a project conceived and developed at NASA Lewis Research Center. The CSD flight experiment was conducted in the Middeck Glovebox Facility (MGBX) on USMP-3. The project is support by NASA Headquarters Microgravity Science and Applications Division and Code Q. The results presented here are from the microgravity portion of the experiment, including the temporal response of the detectors and average sizes of the primary and aggregate particles captured on the thermophoretic probes.

Geophysical Model Research and Results  

SciTech Connect

Geophysical models constitute an important component of calibration for nuclear explosion monitoring. We will focus on four major topics: (1) a priori geophysical models, (2) surface wave models, (3) receiver function derived profiles, and (4) stochastic geophysical models. The first, a priori models, can be used to predict a host of geophysical measurements, such as body wave travel times, and can be derived from direct regional studies or even by geophysical analogy. Use of these models is particularly important in aseismic regions or regions without seismic stations, where data of direct measurements might not exist. Lawrence Livermore National Laboratory (LLNL) has developed the Western Eurasia and North Africa (WENA) model which has been evaluated using a number of data sets, including travel times, surface waves, receiver functions, and waveform analysis (Pasyanos et al., 2004). We have joined this model with our Yellow Sea - Korean Peninsula (YSKP) model and the Los Alamos National Laboratory (LANL) East Asia model to construct a model for all of Eurasia and North Africa. Secondly, we continue to improve upon our surface wave model by adding more paths. This has allowed us to expand the region to all of Eurasia and into Africa, increase the resolution of our model, and extend results to even shorter periods (7 sec). High-resolution models exist for the Middle East and the YSKP region. The surface wave results can be inverted either alone, or in conjunction with other data, to derive models of the crust and upper mantle structure. We are also using receiver functions, in joint inversions with the surface waves, to produce profiles directly under seismic stations throughout the region. In a collaborative project with Ammon, et al., they have been focusing on stations throughout western Eurasia and North Africa, while we have been focusing on LLNL deployments in the Middle East, including Kuwait, Jordan, and the United Arab Emirates. Finally, we have been exploring methodologies such as Markov Chain Monte Carlo (MCMC) to generate data-driven stochastic models. We have applied this technique to the YSKP region using surface wave dispersion data, body wave travel time data, and receiver functions.

ISO: highlights of recent results  

NASA Astrophysics Data System (ADS)

The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four versatile scientific instruments, it was launched by an Ariane 44P in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the universe at infrared wavelengths (2.5-240 ?m). Its 60-cm diameter telescope was cooled by superfluid liquid helium to temperatures of 2-4 K. The mission was a great technical, operational and scientific success, with most satellite sub-systems operating far better than specifications, while the scientific instruments returned unprecedented results ensuring that its scientific output impacted practically all fields of astronomy. During its routine operational phase, which lasted until April 1998 - almost a year longer than specified, ISO successfully made some 30,000 individual imaging, photometric, spectroscopic and polarimetric observations ranging from objects in our own solar system right out to the most distant extragalactic sources. ISOs data archive - http://www.iso.vilspa.esa.es - opened to the community in December 1998 and, including data from calibration and auxiliary mode observations, contains about 150,000 data sets. Since 1996 to date about 1000 ISO papers have been published in the refereed literature, and many more in conference proceedings. A summary of the mission - including some of its highlights - is presented, followed by a description of current and future activities.

Unfavourable results in craniofacial surgery  

PubMed Central

Craniofacial surgery is one of the newer subspecialties of plastic surgery and owes its birth to the pioneering work of Paul Tessier in the late sixties. Since then this challenging specialty work has been taken up by many centres around the word including India. Initial reports in late eighties and early nineties showed morbidity and mortality ranging from 1.6% to 4.3%. However over past few decades, with improved instrumentations, safer anaesthesia and cumulative experience of surgeons the morbidity and mortality has been brought down to as low as 0.1% in many centres in USA. In our centre at Post-graduate Institute, Chandigarh, the mortality rate is about 0.8% (4 out of 480 cases). The learning curve in this surgery is rather steep but with experience and a well-coordinated team work, results in this complex subspecialty can be improved. The infection is a major cause for worry but can be easily prevented by sound surgical principles and placing a vascularised tissue barrier between the extradural space and the nasopharynx/sinus mucosa.

Visible Nulling Coronagraph Testbed Results  

NASA Technical Reports Server (NTRS)

The Extrasolar Planetary Imaging Coronagraph (EPIC) is a NASA Astrophysics Strategic Mission Concept study and a proposed NASA Discovery mission to image and characterize extrasolar giant planets in orbits with semi-major axes between 2 and 10 AU. EPIC would provide insights into the physical nature of a variety of planets in other solar systems complimenting radial velocity (RV) and astrometric planet searches. It will detect and characterize the atmospheres of planets identified by radial velocity surveys, determine orbital inclinations and masses, characterize the atmospheres around A and F stars, observed the inner spatial structure and colors of inner Spitzer selected debris disks. EPIC would be launched to heliocentric Earth trailing drift-away orbit, with a 5-year mission lifetime. The starlight suppression approach consists of a visible nulling coronagraph (VNC) that enables starlight suppression in broadband light from 480-960 nm. To demonstrate the VNC approach and advance it's technology readiness we have developed a laboratory VNC and have demonstrated white light nulling. We will discuss our ongoing VNC work and show the latest results from the VNC testbed.

Preliminary results of ANAIS-25  

NASA Astrophysics Data System (ADS)

The ANAIS (Annual Modulation with NaI(Tl) Scintillators) experiment aims at the confirmation of the DAMA/LIBRA signal using the same target and technique at the Canfranc Underground Laboratory. 250 kg of ultrapure NaI(Tl) crystals will be used as a target, divided into 20 modules, each coupled to two photomultipliers. Two NaI(Tl) crystals of 12.5 kg each, grown by Alpha Spectra from a powder having a potassium level under the limit of our analytical techniques, form the ANAIS-25 set-up. The background contributions are being carefully studied and preliminary results are presented: their natural potassium content in the bulk has been quantified, as well as the uranium and thorium radioactive chains presence in the bulk through the discrimination of the corresponding alpha events by PSA, and due to the fast commissioning, the contribution from cosmogenic activated isotopes is clearly identified and their decay observed along the first months of data taking. Following the procedures established with ANAIS-0 and previous prototypes, bulk NaI(Tl) scintillation events selection and light collection efficiency have been also studied in ANAIS-25.

The plasma has been heated by up to 5 MW of neutral beam injection, NBI, at an injection energy of 90 keV and up to 6 MW of high harmonic fast wave, HHFW, at 30 MHz. NSTX has achieved beta T of 32%. A variety of MHD phenomena have been observed to limit eta. NSTX has now begun addressing E scaling, eta limits and current drive issues. During the NBI heating experiments, a broad Ti profile with Ti up to 2 keV, Ti > Te and a large toroidal rotation. Transport analysis suggests that the impurity ions have diffusivities approaching neoclassical. For L-Mode plasmas, E is up to two times the ITER-89P L-Mode scaling and exceeds the ITER-98pby2 H-Mode scaling in some cases. Transitions to H-Mode have been observed which result in an approximate doubling of tE. after the transition in some conditions. During HH FW heating, Te > Ti and Te up to 3.5 keV were observed. Current drive has been studied using coaxial helicity injection (CHI), which has produced 390 kA of toroidal current and HHFW, which has produced H-modes with significant bootstrap current fraction at low Ip, high q and high{sub etap}.

Double Chooz: Results and Perspectives  

NASA Astrophysics Data System (ADS)

The Double Chooz experiment has been observing ? from two reactor cores at the Chooz nuclear power station in Ardennes, France, with a single 10.3 m fiducial volume Gd-doped liquid scintillator detector at a flux-weighted average baseline of ˜1050 m. This article reviews results achieved with a detector live time of 227.93 days and exposure of 33.71 GW-ton-years. A total of 8,249 candidate ? events have been observed, compared to an expected 8,937 events in the null-oscillation case: this deficit is interpreted as evidence for ? disappearance. A fit to the observed neutrino rate and spectral shape gives a best-fit value of sin2(2?13)=0.109±0.030 (stat.)±0.025 (syst.) at a mass-squared splitting of ?m312=2.32×10-3 eV. The null-oscillation hypothesis is excluded by the data at 99.8% CL (2.9?). The Double Chooz Near Detector is under construction, and analysis efforts to measure neutrino directionality, test Lorentz violation, and measure backgrounds in situ are underway.

Pulmonary Vascular Angioscopy - Current Results  

NASA Astrophysics Data System (ADS)

We performed angioscopy on 31 patients with suspected chronic pulmonary arterial ob-struction using three prototype angioscopes. The instruments varied in length (80, 90, and 120 cm), outside diameter (3.2 and 4 mm), and distal tip deflection (70, 90, and 180 degrees). All had a distal viewing balloon. Conventional diagnostic studies were performed and decisions about diagnosis and operability were made prior to angioscopy. An independent assessment of diagnosis and operability was then made based on the results of angioscopy. Surgical confirmation was obtained in most cases and clinical or autopsy data were obtained in the remainder. Angioscopy led to a change in the diagnosis of 6 patients (19%). Four of 25 patients with chronic pulmonary emboli were felt to be inoperable based on the angioscopic findings. Two of these 4 underwent surgery and were found to be inoperable. 21 of the remaining 25 patients were felt to have operable disease and 19 underwent surgery. In 14 of these 19 (74%), the conventional studies were either negative or equivocal with respect to operability and the decision to operate was based on angioscopic data. We conclude that good visualization of the central pulmonary arteries can be achieved with the optical balloon technique; that the procedure can be performed safely in patients with severe pulmonary hypertension; and that the information obtained by angioscopy can significantly affect clinical decisions in patients with chronic pulmonary artery obstruction.

KEPLER: Status, Results, and Plans  

NASA Astrophysics Data System (ADS)

Analysis of current Kepler observations show the presence of over 2300 candidate planets, over 2200 eclipsing binary stars, and variable stars of amazing variety. The sizes of planetary candidates range from that of Mars to over twice the size of Jupiter. Fiftynine candidates are found in the habitable zone of the host stars. Candidates as small as Mars in short period orbits are being detected. Three circumbinary planets have been confirmed and many more await analyis. More than 300 multi-planet candidates have been found. Statistical analysis shows that 99% of the candidates must be valid planetary systems rather than false positive events. In addition to radial velocity measurements, gravitational interaction between planets in near-resonant orbits is being used to determine planet masses and thus the density of the planets. A search for planetary moons is underway. Ongoing follow-up spectroscopic observations and their analyses are providing improvements compared to the values in the Kepler Input Catalog for the stellar temperatures, sizes and metallicities for many of the stars that have become Kepler Objects of Interest (KOI). In particular, the re-analysis of KOI 961 has shown that the planets orbiting it are much smaller than expected; two are slightly smaller than Earth and one is the size of Mars. Intrinsic distributions of the candidates out to periods of 150 days are derived that allow estimates of the frequency distributions of planet size with semi-major axis and orbital period and to associate the results with stellar characteristics.

Dissociated methanol vehicle test results  

SciTech Connect

This paper presents the results of chassis dynamometer testing of a 1980 Chevrolet Citation modified to run on dissociated methanol. Data are presented on the composition of the dissociated methanol gas during steady-state operation, vehicle fuel consumption during steady-state and transient operation, and exhaust emissions during transient operation. During low speed, low load operation there are significant amounts of unconverted methanol and side products to the desired dissociation reaction. Despite this, fuel economy improvements over baseline gasoline operation are high. Fuel economies of 13.3 km/L (31.3 mpg) and 11.4 km/L (26.8 mpg) were obtained at steady speed road load conditions of 65 km/h and 90 km/h respectively. Methanol fuel economy over the EPA '74 CVS hot start city driving cycle was 7.74 km/L (18.2 mpg). Methanol fuel economy over the EPA highway fuel economy test was 10.2 km/L (24.0 mpg).

Majorana Thermosyphon Prototype Experimental Results  

SciTech Connect

Objective The Majorana demonstrator will operate at liquid Nitrogen temperatures to ensure optimal spectrometric performance of its High Purity Germanium (HPGe) detector modules. In order to transfer the heat load of the detector module, the Majorana demonstrator requires a cooling system that will maintain a stable liquid nitrogen temperature. This cooling system is required to transport the heat from the detector chamber outside the shield. One approach is to use the two phase liquid-gas equilibrium to ensure constant temperature. This cooling technique is used in a thermosyphon. The thermosyphon can be designed so the vaporization/condensing process transfers heat through the shield while maintaining a stable operating temperature. A prototype of such system has been built at PNNL. This document presents the experimental results of the prototype and evaluates the heat transfer performance of the system. The cool down time, temperature gradient in the thermosyphon, and heat transfer analysis are studied in this document with different heat load applied to the prototype.

First Results from SHIP Experiment  

SciTech Connect

At present, the GDT facility is being upgraded. The first stage of the upgrade is the Synthesised Hot Ion Plasmoid (SHIP) experiment. It aims, on the one hand, at the investigation of plasmas which are expected to appear in the region of high neutron production in a GDT based fusion neutron source proposed by the Budker Institute and, on the other hand, at the investigation of plasmas the parameters of which have never been achieved before in axisymmetric magnetic mirrors.The experiment is performed in a small mirror section which is installed at the end of one side of GDT. The magnetic field on axis is in the range of 0.5-2.0 Tesla and the mirror ratio is 1.2-1.4. The mirror is filled with background plasma streaming in from the central cell. This plasma component is maxwellised and has an electron temperature of about 100 eV. Two neutral beam injectors perpendicularly inject a total current of about 50 Atom Amperes of deuterium neutrals with an energy of 20 keV as a pulse with a duration of about 1 ms. Ionisation of the beams generates the high-energy ion component. The device has been equipped with several diagnostic methods which are successfully used in GDT experiments.The paper presents first results of plasma parameter measurements in SHIP experiment.

Results from the PAMELA experiment.  

NASA Astrophysics Data System (ADS)

PAMELA is a satellite-borne experiment, aimed at precision measurements of the charged, light component of the cosmic-ray spectrum. It consists of a magnetic spectrometer, a time-of-flight system, an electromagnetic calorimeter, an anticoincidence system and a neutron detector. The main focus of the experiment is on antimatter; other components of the spectrum that can be investigated include electrons and light nuclei up to oxygen. Thanks to its placement out of the terrestrial atmosphere and the long exposure time, PAMELA is able to provide data with low systematic effects and high statistical significance. Its semi-polar orbit allows to detect particles of solar origin and to investigate the effects of the solar activity on the low-energy part of the galactic component of the spectrum (solar modulation). The redundancy of its detectors allows to monitor the detector performance and to measure the data selection efficiency directly from flight data. The instrument has been launched in 2006 and it is continuously taking data since then. The most important and recent results from the experiment will be presented.

Polysulfated derivatives of beta-cyclodextrin and myo-inositol as potent inhibitors of the interaction between L-selectin and peripheral addressin: implying a requirement for highly clustered sulfate groups.  

PubMed

We have utilized an in vitro assay that measures the binding of an L-selectin-human Fc chimera (LS-Fc) to [35S]sulfate labelled peripheral addressin (PNAd), a 120 kDa glycoprotein ligand for L-selectin in porcine lymph nodes, to evaluate inhibitory properties of a small group of sulfated derivatives of beta-cyclodextrin (beta-CD), sLe(x) and myo-inositol to their non-sulfated counterparts were studied. We found that hepta-sulfated beta-CD (IC50 = 0.2 mM) strongly inhibited the binding of L-selectin to PNAd. In contrast, the monosulfated beta-CD was a poor inhibitor, displaying < 10% inhibition at 0.5 mM and beta-CD was not active as an inhibitor. Similarly, inositol hexakissulfate, a compound containing six sulfate groups on the inositol ring displayed an inhibition of about 61% at 0.5 mM concentration, whereas the non-sulfated myoinositol was not inhibitory. These findings provide evidence that clustering of sulfate groups enhances affinity of molecules for binding to L-selectin. PMID:8954925

An overview of FTU results  

NASA Astrophysics Data System (ADS)

Since the 2010 IAEA-FEC Conference, FTU has exploited improvements in cleaning procedures and in the density control system to complete a systematic exploration of access to high-density conditions in a wide range of plasma currents and magnetic fields. The line-averaged densities at the disruptive limit increased more than linearly with the toroidal field, while no dependence on plasma current was found; in fact, the maximum density of 4.3 × 1020 m-3 was reached at B = 8 T even at the minimum current of 0.5 MA, corresponding to twice the Greenwald limit. The lack of plasma current dependence was due to the increase in density peaking with the safety factor. Experiments with the 140 GHz electron cyclotron resonance heating (ECRH) system were focused on the sawtooth (ST) period control and on the commissioning of a new launcher with real-time steering capability that will act as the front-end actuator of a real-time system for ST period control and tearing mode stabilization. Various ECRH and electron cyclotron current-drive modulation schemes were used; with the fastest one, the ST period synchronized with an 8 ms modulation period. The observed period variations were simulated using the JETTO code with a critical shear model for the crash trigger. The new launcher was of the plug-in type, allowing quick insertion and connection to the transmission line. Both beam characteristics and steering speed were in line with design expectation. Experimental results on the connection between improved coupling of lower hybrid waves in high-density plasmas and reduced wave spectral broadening were interpreted by fully kinetic, non-linear model calculations. A dual-frequency, time-of-flight diagnostic for the measurement of density profiles was developed and successfully tested. Fishbone-like instabilities driven by energetic electrons were simulated by the hybrid MHD-gyrokinetic XHMGC code.

Transconjunctival dacryocystorhinostomy: Long term results  

PubMed Central

Purpose To evaluate the outcomes of transconjunctival dacryocystorhinostomy (TRC-DCR) surgery in patients with epiphora due to primary acquired nasolacrimal duct obstruction (PANDO) at second year follow-up. Methods In this retrospective, interventional study, 33 eyes of 29 patients, with epiphora due to PANDO, are included. Lower eyelid conjunctiva is incised at vestibulum inferomedially to access the lacrimal sac and nasal mucosa. Bone is perforated with burr and rongeurs and saccal and nasal flaps are anastomosed. Conjunctival wound edges are apposed and left unsutured. Intraoperative difficulties, surgical time and complications are noted. Average follow-up time was 2 years. Anatomical success was defined as patent lacrimal passages upon irrigation and functional success was defined as relief of epiphora. Results In nineteen (57.6%) eyes the surgeries were completed with the anterior and the posterior flaps sutured. In eight eyes (24.2%) only anterior flaps could be sutured. In 6 eyes (18.2%), the surgical procedure was converted to external dacryocystorhinostomy since the nasal mucosa could not be exposed adequately via transconjunctival route. The mean surgical time was 65.1 min. One patient had a millimeter long lower eyelid margin laceration in one eye (3.7%) intraoperatively due to traction for visualization of the operative site. Epiphora resolved in 25 of 27 eyes (92.5%) in whom TRC-DCR could be completed. Epiphora and failure to irrigation were noted in two eyes (7.4%) at the postoperative 4th and 8th months, respectively and required reoperation. No complications occurred, except granuloma formation at the conjunctival incision site in three eyes (11.1%). Epiphora resolved in all the six eyes of patients who underwent an external DCR (100%). Conclusion Transconjunctival dacryocystorhinostomy is a scarless dacryocystorhinostomy technique which is performed without endoscope and/or laser assistance, with 92.5% success rate comparable to external DCR at the second year follow-up without major complications.

[Results of percutaneous transluminal angioplasty].  

PubMed

Percutaneous transluminal angioplasty (PTA) can be subdivided into three epochs: 1. from its inception by Dotter and Judkins up to the first coronary artery stenosis dilatation with the Grüntzig balloon catheter system; 2. from the introduction of coronary stenosis dilatation by Grüntzig up to its unequivocal acceptance; 3. the period of influence of low-risk coronary dilatation on peripheral angioplasty and the search for techniques to compliment or obviate the need for balloon dilatation. The Grüntzig double-lumen balloon catheter system contributed to the lower rate of complications and higher success rate. The clinical acceptance appeared greater for the coronary arteries since, in contrast to the peripheral vascular system, the indication for treatment is established by the physician performing the dilatation. PTA implies percutaneous puncture of a vessel with Seldinger technique and introduction of devices such as guidewires, Dotter or Grüntzig catheters among others, catheters with fiberglass for laser conduction and instruments for fractionating, drilling and cutting. The goal of PTA is to completely or partially eliminate, without surgery, intraluminal vascular narrowing in the presence of peripheral arterial disease in stage II, III or IV. Prerequisite to the use of PTA are: 1. adequate fluoroscopic and angiographic facilities; 2. adequate instrumentation; 3. experience with at least 200 procedures; 4. knowledge of the pathophysiology and adjunctive treatment; 5. knowledge of the treatment of complications; 6. cooperation with a vascular surgery service. A number of factors may influence the results of treatment. Adjunctive medical treatment: the use of platelet aggregation inhibitors and heparin influences the rate of early rethrombosis.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2522077

Corral Monitoring System assessment results  

SciTech Connect

This report describes the results of a functional and operational assessment of the Corral Monitoring Systems (CMS), which was designed to detect and document accountable items entering or leaving a monitored site. Its development was motivated by the possibility that multiple sites in the nuclear weapons states of the former Soviet Union might be opened to such monitoring under the provisions of the Strategic Arms Reduction Treaty. The assessment was performed at three levels. One level evaluated how well the planned approach addressed the target application, and which involved tracking sensitive items moving into and around a site being monitored as part of an international treaty or other agreement. The second level examined the overall design and development approach, while the third focused on individual subsystems within the total package. Unfortunately, the system was delivered as disassembled parts and pieces, with very poor documentation. Thus, the assessment was based on fragmentary operating data coupled with an analysis of what documents were provided with the system. The system design seemed to be a reasonable match to the requirements of the target application; however, important questions about site manning and top level administrative control were left unanswered. Four weaknesses in the overall design and development approach were detected: (1) poor configuration control and management, (2) inadequate adherence to a well defined architectural standard, (3) no apparent provision for improving top level error tolerance, and (4) weaknesses in the object oriented programming approach. The individual subsystems were found to offer few features or capabilities that were new or unique, even at the conceptual level. The CMS might possibly have offered a unique combination of features, but this level of integration was never realized, and it had no unique capabilities that could be readily extracted for use in another system.

Mobile evaporator corrosion test results  

SciTech Connect

Laboratory corrosion tests were conducted on eight candidates to select a durable and cost-effective alloy for use in mobile evaporators to process radioactive waste solutions. Based on an extensive literature survey of corrosion data, three stainless steel alloys (304L, 316L, AL-6XN), four nickel-based alloys (825, 625, 690, G-30), and titanium were selected for testing. The corrosion tests included vapor phase, liquid junction (interface), liquid immersion, and crevice corrosion tests on plain and welded samples of candidate materials. Tests were conducted at 80{degrees}C for 45 days in two different test solutions: a nitric acid solution. to simulate evaporator conditions during the processing of the cesium ion-exchange eluant and a highly alkaline sodium hydroxide solution to simulate the composition of Tank 241-AW-101 during evaporation. All of the alloys exhibited excellent corrosion resistance in the alkaline test solution. Corrosion rates were very low and localized corrosion was not observed. Results from the nitric acid tests showed that only 316L stainless steel did not meet our performance criteria. The 316L welded interface and crevice specimens had rates of 22.2 mpy and 21.8 mpy, respectively, which exceeds the maximum corrosion rate of 20 mpy. The other welded samples had about the same corrosion resistance as the plain samples. None of the welded samples showed preferential weld or heat-affected zone (HAZ) attack. Vapor corrosion was negligible for all alloys. All of the alloys except 316L exhibited either {open_quotes}satisfactory{close_quotes} (2-20 mpy) or {open_quotes}excellent{close_quotes} (<2 mpy) corrosion resistance as defined by National Association of Corrosion Engineers. However, many of the alloys experienced intergranular corrosion in the nitric acid test solution, which could indicate a susceptibility to stress corrosion cracking (SCC) in this environment.

[Results for SHEBA/FIRE  

NASA Technical Reports Server (NTRS)

The Atmospheric Research Laboratory's Radiation Measurement System (RAMS) was on the NCAR C-130 aircraft in May and July 1998, collecting radiometric data on the science flights conducted in the vicinity of the Surface Heat Budget of the Arctic Ocean (SHEBA) ship. These measurements were part of the FIRE Arctic Cloud Experiment (FIRE ACE). Analysis of some of the data focused on the absorption, reflection, and transmittance of Arctic clouds, especially compared to model results. In order to assess the absorption of solar radiation by the clear and cloudy atmosphere in the Arctic the measurements from the radiometers were combined in pairs of above-cloud segments and below-cloud segments. To get these pairs, the data for all sixteen of the flights (8 in May and 8 in July) were examined for occurrences of low-altitude segments in proximity to high-altitude segments. The low-altitude data are then treated as measurements of the bottom of a layer and the high-altitude data are taken as measurements of the top of the layer. With measurements of the upwelling and downwelling irradiances above and below a layer one can determine the reflectance, transmittance, and absorptance of the layer. Attachment: Doelling, D.R., P.

Results of nonendoscopic endonasal dacryocystorhinostomy  

PubMed Central

Background Surgical scarring on the face and disrupted anatomy in the medial canthal area following external dacryocystorhinostomy (DCR) can be avoided by an endonasal approach. This study examined the outcome of direct visualization endonasal DCR, performed by young surgeons and residents. Methods A retrospective case series of 75 consecutive endonasal DCRs performed under direct visualization from July 2002 to July 2004 were reviewed. Surgery was performed by surgeons and residents who had received no special training in the procedure. Full success was defined as no symptoms of tearing after surgery and anatomical patency with fluorescein flow on nasal endoscopy or patency to lacrimal syringing. Partial success was defined as a tearing decrease compared with prior to surgery and with anatomical patency, and failure was defined as no significant improvement in persistent tearing. The average follow-up duration was 26.83 ± 16.26 (range 6–55) months. Results Seventy-five DCRs were performed on 63 patients (four male, 59 female) of mean age 49.44 ± 16.63 (range 21–85) years. The surgery was successful in 54/75 eyes (72%), 37/54 eyes (68.5%), and 30/42 eyes (71.4%) at 6, 12, and 24 months, respectively. Partial success was achieved in 13/75 (17.3%), 9/54 (16.7%), and 9/42 (21.4%), and the failure rates were 10.7%, 14.8%, and 7.1% at 6, 12, and 24 months, respectively. The overall functional success with this technique was 74.7% and the overall anatomical patency was 92.0%. There were no serious complications arising from the surgery; three minor complications were documented, ie, an incorrectly placed silicone tube in the lower canaliculus, tube prolapse, and postoperative bleeding which needed nasal packing and eventually a developed retention cyst in the nasal cavity. Conclusion Endonasal DCR under direct visualization is a simple technique with minimal complications and a low learning curve, without the necessity for expensive instruments. PMID:22927743

Overview of the FTU results  

NASA Astrophysics Data System (ADS)

Spontaneous increases in plasma density, up to ~1.6 times the Greenwald value, are observed in FTU with lithized walls. These plasmas are characterized by profile peaking up to the highest obtained densities. The transport analysis of these discharges shows a 20% enhancement of the energy confinement time, with respect to the ITER97 L-mode scaling, correlated with a threshold in the peaking factor. It has been found that 0.4 MW of ECRH power, coupled at q = 2 surface, are sufficient to avoid disruptions in 0.5 MA discharges. Direct heating of magnetic islands produced by MHD modes determines current quench delay or avoidance. Supra-thermal electrons generated by 0.5 MW of lower hybrid power are sufficient to trigger precursors of the electron-fishbone instability. Evidence of spatial redistribution of fast electrons, on the ~100 µs typical mode timescale, is shown by the fast electrons bremsstrahlung diagnostic. From the presence of new magnetic island induced accumulation points in the continuous spectrum of the shear Alfvén wave spectrum, the existence of new magnetic island induced Alfvén eigenmodes (MiAE) is suggested. Due to the frequency dependence on the magnetic island size, the feasibility of utilizing MiAE continuum effects as a novel magnetic island diagnostic is also discussed. Langmuir probes have been used on FTU to identify hypervelocity (10 km s-1), micrometre size, dust grains. The Thomson scattering diagnostic was also used to characterize the dust grains, present in the FTU vacuum chamber, following a disruption. Analysis of the broad emitted light spectrum was carried out and a model taking into account the particle vaporization is compared with the data. A new oblique ECE diagnostic has been installed and the first results, both in the presence of lower hybrid or electron cyclotron waves, are being compared with code predictions. A time-of-flight refractometer at 60 GHz, which could be a good candidate for the ITER density feedback control system, has also been tested.

Overview of ASDEX Upgrade results  

NASA Astrophysics Data System (ADS)

The medium size divertor tokamak ASDEX Upgrade (major and minor radii 1.65 m and 0.5 m, respectively, magnetic-field strength 2.5 T) possesses flexible shaping and versatile heating and current drive systems. Recently the technical capabilities were extended by increasing the electron cyclotron resonance heating (ECRH) power, by installing 2 × 8 internal magnetic perturbation coils, and by improving the ion cyclotron range of frequency compatibility with the tungsten wall. With the perturbation coils, reliable suppression of large type-I edge localized modes (ELMs) could be demonstrated in a wide operational window, which opens up above a critical plasma pedestal density. The pellet fuelling efficiency was observed to increase which gives access to H-mode discharges with peaked density profiles at line densities clearly exceeding the empirical Greenwald limit. Owing to the increased ECRH power of 4 MW, H-mode discharges could be studied in regimes with dominant electron heating and low plasma rotation velocities, i.e. under conditions particularly relevant for ITER. The ion-pressure gradient and the neoclassical radial electric field emerge as key parameters for the transition. Using the total simultaneously available heating power of 23 MW, high performance discharges have been carried out where feed-back controlled radiative cooling in the core and the divertor allowed the divertor peak power loads to be maintained below 5 MW m-2. Under attached divertor conditions, a multi-device scaling expression for the power-decay length was obtained which is independent of major radius and decreases with magnetic field resulting in a decay length of 1 mm for ITER. At higher densities and under partially detached conditions, however, a broadening of the decay length is observed. In discharges with density ramps up to the density limit, the divertor plasma shows a complex behaviour with a localized high-density region in the inner divertor before the outer divertor detaches. Turbulent transport is studied in the core and the scrape-off layer (SOL). Discharges over a wide parameter range exhibit a close link between core momentum and density transport. Consistent with gyro-kinetic calculations, the density gradient at half plasma radius determines the momentum transport through residual stress and thus the central toroidal rotation. In the SOL a close comparison of probe data with a gyro-fluid code showed excellent agreement and points to the dominance of drift waves. Intermittent structures from ELMs and from turbulence are shown to have high ion temperatures even at large distances outside the separatrix.

Recent Opportunity Microscopic Imager Results  

NASA Astrophysics Data System (ADS)

Opportunity arrived at exposures of Endeavour crater rim rocks in August 2011, on a hill dubbed 'Cape York.' These rocks have been the goal of exploration by Opportunity for the past few years because spectral evidence for phyllosilicates was observed at this location in orbital remote sensing data. As Opportunity circum¬navigated Cape York, the Microscopic Imager (MI) was used to examine the fine-scale textures of various soils and rocky outcrops. As reported previously, Opportunity discovered multiple bright linear features along the western periphery of Cape York that have been interpreted as veins of Ca sulfate deposited in fractures within the bedrock of Cape York. Opportunity then explored the northern and eastern sides of Cape York, including the area around 'Matijevic Hill' that shows evidence for phyllosilicates in CRISM data acquired from the Mars Reconnaissance Orbiter. One of the first outcrops examined near Matijevic Hill, dubbed 'Kirkwood,' is dominated by millimeter-size spherules. Unlike the hematite-rich concretions observed by Opportunity on Meridiani Planum, the aggregated 'newberries' in the Kirkwood exposure display internal structure and resistant rims. Compositionally, the spherule-rich rock is very similar to a nearby spherule-poor outcrop dubbed 'Whitewater Lake.' Thus these spherules have a more basalt-like composition compared to the hematite-rich concretions of the Burns Formation. The origin of the Kirkwood outcrop is uncertain, but the setting on the rim of the 22-km diameter Endeavour crater suggests that perhaps impact melting was involved in lapilli formation, possibly followed by mobilization and sorting in the ejecta blanket. Alternatively, the newberries may be diagenetic iron oxide concretions that are less well cemented than the 'blueberries' of the younger sulfate-rich Burns Formation. The Whitewater Lake outcrops contain the phyllosilicate phases observed from orbit, and are the oldest materials yet investigated by Opportunity. The extremely soft bedrock exposed at a Whitewater Lake outcrop target dubbed 'Azilda' is mostly fine-grained, with dispersed 2-5 mm-diameter spherules and resistant veins. This target was easily abraded by the RAT, exposing a sandstone-like texture, but the sorting of grains is difficult to determine at MI resolution. Darker, erosion-resistant veneers, similar to desert varnishes on Earth, appear to record aqueous alteration that post-dates the formation of the Ca sulfate veins; they likely contain the nontronite that is observed by CRISM in this area. The inferred neutral pH and relatively low temperature of the fluids involved in these phases of alteration would have provided a habitable environment for life if it existed on Mars at that time. Because Opportunity can no longer directly sense phyllosilicate mineralogy with the MiniTES or Mössbauer spectrometers, it is focusing on characterizing the chemistry with the APXS and texture with the MI of potential phyllosilicate host rocks. The Athena MI continues to return useful images of Mars that are being used to study the textures of rocks and soils at Endeavour crater. Exploration by Opportunity continues, with the rover approaching 'Solander Point' and more exposures of phyllosilicates detected from orbit; the latest MI results will be presented at the conference.

SMOS first results over land  

NASA Astrophysics Data System (ADS)

The Soil Moisture and Ocean Salinity (SMOS) mission is ESA's (European Space Agency ) second Earth Explorer Opportunity mission, launched in November 2009. It is a joint programme between ESA CNES (Centre National d'Etudes Spatiales) and CDTI (Centro para el Desarrollo Tecnologico Industrial). SMOS carries a single payload, an L-band 2D interferometric radiometer in the 1400-1427 MHz protected band. This wavelength penetrates well through the atmosphere and hence the instrument probes the Earth surface emissivity. Surface emissivity can then be related to the moisture content in the first few centimeters of soil, and, after some surface roughness and temperature corrections, to the sea surface salinity over ocean. In order to prepare the data use and dissemination, the ground segment will produce level 1 and 2 data. Level 1 consists mainly of angular brightness temperatures while level 2 consists of geophysical products. In this context, a group of institutes prepared the soil moisture and ocean salinity Algorithm Theoretical Basis documents (ATBD) to be used to produce the operational algorithm. The principle of the soil moisture retrieval algorithm is based on an iterative approach which aims at minimizing a cost function given by the sum of the squared weighted differences between measured and modelled brightness temperature (TB) data, for a variety of incidence angles. This is achieved by finding the best suited set of the parameters which drive the direct TB model, e.g. soil moisture (SM) and vegetation characteristics. Despite the simplicity of this principle, the main reason for the complexity of the algorithm is that SMOS "pixels" can correspond to rather large, inhomogeneous surface areas whose contribution to the radiometric signal is difficult to model. Moreover, the exact description of pixels, given by a weighting function which expresses the directional pattern of the SMOS interferometric radiometer, depends on the incidence angle. The goal is to retrieve soil moisture over fairly large and thus inhomogeneous areas. The retrieval is carried out at nodes of a fixed Earth surface grid. To achieve this purpose, after checking input data quality and ingesting auxiliary data, the retrieval process per se can be initiated. This cannot be done blindly as the direct model will be dependent upon surface characteristics. It is thus necessary to first assess what is the dominant land use of a node. For this, an average weighing function (MEAN_WEF) which takes into account the "antenna"pattern is run over the high resolution land use map to assess the dominant cover type. This is used to drive the decision tree which, step by step, selects the type of model to be used as per surface conditions. All this being said and done the retrieval procedure starts if all the conditions are satisfied, ideally to retrieve 3 parameters over the dominant class (the so-called rich retrieval). If the algorithm does not converge satisfactorily, a new trial is made with less floating parameters ("poorer retrieval") until either results are satisfactory or the algorithm is considered to fail. The retrieval algorithm also delivers whenever possible a dielectric constant parameter (using the-so called cardioid approach). Finally, once the retrieval converged, it is possible to compute the brightness temperature at a given fixed angle (42.5°) using the selected forward models applied to the set of parameters obtained at the end of the retrieval process. So the output product of the level 2 soil moisture algorithm should be node position, soil moisture, dielectric constants, computed brightness temperature at 42.5°, flags and quality indices. During the presentation we will describe in more details the algorithm and accompanying work in particular decision tree principle and characteristics, the auxiliary data used and the special and "exotic"cases. We will also be more explicit on the algorithm validation and verification through the data collected during the commissioning phase. The main hurdle bein

Overview of ASDEX Upgrade results  

NASA Astrophysics Data System (ADS)

Ion and electron temperature profiles in conventional L and H mode on ASDEX Upgrade are generally stiff and limited by a critical temperature gradient length ?T/T as given by ion temperature gradient (ITG) driven turbulence. ECRH experiments indicate that electron temperature (Te) profiles are also stiff, as predicted by electron temperature gradient turbulence with streamers. Accordingly, the core and edge temperatures are proportional to each other and the plasma energy is proportional to the pedestal pressure for fixed density profiles. Density profiles are not stiff, and confinement improves with density peaking. Medium triangularity shapes (?<0.45) show strongly improved confinement up to the Greenwald density nGW and therefore higher ?values, owing to increasing pedestal pressure, and H mode density operation extends above nGW. Density profile peaking at nGW was achieved with controlled gas puffing rates, and first results from a new high field side pellet launcher allowing higher pellet velocities are promising. At these high densities, small type II ELMs provide good confinement with low divertor power loading. In advanced scenarios the highest performance was achieved in the improved H mode with HL-89P?N approx 7.2 at ? = 0.3 for five confinement times, limited by neoclassical tearing modes (NTMs) at low central magnetic shear (qmin approx 1). The T profiles are still governed by ITG and trapped electron mode (TEM) turbulence, and confinement is improved by density peaking connected with low magnetic shear. Ion internal transport barrier (ITB) discharges - mostly with reversed shear (qmin>1) and L mode edge - achieved HL-89P <= 2.1 and are limited to ?N <= 1.7 by internal and external ideal MHD modes. Turbulence driven transport is suppressed, in agreement with the E × B shear flow paradigm, and core transport coefficients are at the neoclassical ion transport level, where the latter was established by Monte Carlo simulations. Reactor relevant ion and electron ITBs with Te approx Ti approx 10 keV were achieved by combining ion and electron heating with NBI and ECRH, respectively. In low current discharges full non-inductive current drive was achieved in an integrated high performance H mode scenario with [`n]e = nGW, high ?p = 3.1, ?N = 2.8 and HL-89P = 1.8, which developed ITBs with qmin approx 1. Central co-ECCD at low densities allows a high current drive fraction of >80%, while counter-ECCD leads to negative central shear and formation of an electron ITB with Te(0)>12 keV. MHD phenomena, especially fishbones, contribute to achieving quasi-stationary advanced discharge conditions and trigger ITBs, which is attributed to poloidal E × B shearing driven by redistribution of resonant fast particles. But MHD instabilities also limit the operational regime of conventional (NTMs) and advanced (double tearing, infernal and external kink modes) scenarios. The onset ?N for NTM is proportional to the normalized gyroradius ?*. Complete NTM stabilization was demonstrated at ?N = 2.5 using ECCD at the island position with 10% of the total heating power. MHD limits are expected to be extended using current profile control by off-axis current drive from more tangential NBI combined with ECCD and wall stabilization. Presently, the ASDEX Upgrade divertor is being adapted to optimal performance at higher ?'s and tungsten covering of the first wall is being extended on the basis of the positive experience with tungsten on divertor and heat shield tiles.

Sugar cane bagasse as a possible source of fermentable carbohydrates. I. Characterization of bagasse with regard to monosaccharide, hemicellulose, and amino acid composition  

SciTech Connect

Hemicellulose fractions of plant materials have recently attracted attention as a possible source of fermentable sugars to be used via fermentation for the production of liquid fuels, mainly ethanol. Individual monosaccharides present in bagasse hemicellulose were determined using HPLC and other chromatographic procedures. The presence of higher oligomers of the monosaccharides could also be determined. The pentosan fraction of bagasse was successfully hydrolyzed and extracted with 5% (m/v) HCl, and the rate of release of individual monosaccharides was determined. Xylose was the main component in the hydrolyzates, while glucose, arabinose, and galactose present in the side chains of the pentosans were initially released at a fast rate. This treatment resulted in obtaining 229 mg/g xylose (85% of theoretical maximum) and 44 mg/g glucose from bagasse. Only arabinose (2.8 mg/g) and galactose (0.75 mg/g) was also present in detectable quantities. A total of 309 mg monosaccharides were obtained from 1 g of bagasse by this treatment. The results indicated that hydrolysis conditions for specific plant materials depend on the composition of the specific material being utilized. A part of the pentosan fraction (77.1%) was hydrolyzed at a high rate, while 22.9% was more stable and hydrolyzed more slowly. Although 39.8% dry bagasse could be obtained in solution by treatment with dilute alkali, only about 72% of the available hemicelluloses could be extracted in this way if the bagasse was not delignified beforehand. Amino acids and peptides or proteins were also extracted to very much the same extent with the alkali.

Disclosing individual genetic results to research participants.  

PubMed

Investigators and institutional review boards should integrate plans about the appropriate disclosure of individual genetic results when designing research studies. The ethical principles of beneficence, respect, reciprocity, and justice provide justification for routinely offering certain results to research participants. We propose a result-evaluation approach that assesses the expected information and the context of the study in order to decide whether results should be offered. According to this approach, the analytic validity and the clinical utility of a specific result determine whether it should be offered routinely. Different results may therefore require different decisions even within the same study. We argue that the threshold of clinical utility for disclosing a result in a research study should be lower than the threshold used for clinical use of the same result. The personal meaning of a result provides additional criteria for evaluation. Finally, the context of the study allows for a more nuanced analysis by addressing the investigators' capabilities for appropriate disclosure, participants' alternative access to the result, and their relationship with the investigators. This analysis shows that the same result may require different decisions in different contexts. PMID:17085395

Fast result normalization in FP adder  

Microsoft Academic Search

Floating-point adders use double-path structure to reduce the latency. In the present implementation there are two paths: NORMALIZING and ROUNDING. The NORMALIZING path includes significand adder, normalization shift amount generator, normalizer, result exponent correction adder. The MSBs of the shift amount for result normalization are anticipated, and the LSBs of the shift amount are detected. Both parts of the shift

Common text clustering techniques offer rather poor capabilities for explaining to their users why a particular result has been achieved. They have the disadvantage that they do not relate semantically nearby terms and that they cannot explain how resulting clusters are related to each other. In this paper, we discuss a way of integrating a large thesaurus and the computation

Chemical properties of two-year-old deciduous species  

SciTech Connect

Contents of ash, hot-water extractives, 1% sodium hydroxide extractives, alcohol-benzene extractive, lignin, holocellulose, alpha-cellulose, and pentosan were determined on two-year-old, short-rotation trees of autumn olive, black alder, black locust, eastern cottonwood, royal paulownia, silver maple, and sycamore. These plantations were established in 1978 on marginal agricultural land that was not suitable for food production in Illinois. Six comparable species of commercial lumber were also analyzed. Test results indicated that all chemical properties did vary with species, above-ground tree portions, and ages of species. The two-year-old juvenile trees had higher average extractives, holocellulose, pentosan, and ash content than did the lumber of matured wood. Black locust possessed the highest values of holocellulose and alpha-cellulose, while the eastern cottonwood had the highest extractive contents. Silver maple had the highest lignin content. Both bark and branches which consisted of about 32% of the mass weight of young trees, had a higher average lignin, extractive and ash content than those of the stemwood. Based on chemical composition, these seven juvenile deciduous species could serve as a raw material for the paper and chemical industries, as well as for energy. 19 references, 8 figures, 6 tables.

The National Cancer Institute (NCI) and the National Toxicology Program (NTP) have carried out a number of laboratory animal carcinogenicity studies and presented the results of these experiments in a series of Technical Reports. This paper tabulates the results of the 327 NCI/NTP studies carried out to date on 308 distinct chemicals, and discusses certain issues relevant to the evaluation of carcinogenicity in these experiments. This compilation of results from NCI/NTP carcinogenicity experiments provides a large database that can be used to study structure-activity correlations, interspecies concordance, and associations between laboratory animal carcinogenicity and other toxicological effects.

Unfavourable results in skull base surgery.  

PubMed

Treatment of skull base tumors involves multiple specialities. The lesions are usually advanced and the treatment is often associated with unfavorable results, which may be functional and/or aesthetic. Here we have done an analysis for the complications and unfavorable results of 546 cases treated surgically by a single craniofacial surgeon over a period of 14 years. The major morbidity ranges from death to permanent impairment of vital organ functions (brain, eye, nose), infections, tissue losses, flap failures, treatment associated complications, psychosocial issues, and aesthesis besides others. This article is aimed at bringing forth these unfavorable results and how to avoid them. PMID:24501460

Reconciling the CAST and PVLAS Results  

E-print Network

The PVLAS experiment has recently claimed evidence for an axion-like particle in the milli-electron-Volt mass range with a coupling to two photons that appears to be in contradiction with the negative results of the CAST experiment searching for solar axions. The simple axion interpretation of these two experimental results is therefore untenable and it has posed a challenge for theory. We propose a possible way to reconcile these two results by postulating the existence of an ultralight pseudo-scalar particle interacting with two photons and a scalar boson and the existence of a low scale phase transition in the theory.

SMOS mission main results and new venues  

NASA Astrophysics Data System (ADS)

In early November 2012, the SMOS mission celebrated 3 years in orbit. Since its launch, this mission has given many opportunities for breaking new grounds. Shortly after launch, first global maps of soil moisture ever measured from space were produced. Since then, the achieved accuracy has continuously improved to match the requirements. The long term trends of surface moisture can now be closely linked to precipitation regime, and SMOS results have been successfully used in response to extreme events. On the other hand, ocean salinity results have also improved dramatically. Here again, some amazing results regarding river plumes or fresh water pools related to precipitation have been obtained. At last, new applications have been imagined in various fields such as of sea ice thickness, or hurricane winds. This presentation will give an extensive status of the mission, emphasizing the many lessons learned and demonstrating some outstanding results. Some perspectives on the mission and future missions will also be given.

Specific results from the Pioneer 10 mission and a 'first look' at the Pioneer 11 results from the 13 scientific instruments are presented. The particle and field phenomena measured within the Jovian radiation belt present a consistent picture which is, in general, an environment more severe and dynamic than that predicted by earth-based observations.

The notion of soft sets is introduced as a general mathematical tool for dealing with uncertainty. In this paper, we consider the concepts of soft compactness, countably soft compactness and obtain some results. We study some soft separation axioms that have been studied by Min and Shabir-Naz. By constructing a special soft topological space, show that some classical results in general topology are not true about soft topological spaces, for instance every compact Housdorff spaces need not be normal.

Review of recent irradiation-creep results  

SciTech Connect

Materials deform faster under stress in the presence of irradiation by a process known as irradiation creep. This phenomenon is important to reactor design and has been the subject of a large number of experimental and theoretical investigations. The purpose of this work is to review the recent experimental results to obtain a summary of these results and to determine those research areas that require additional information. The investigations have been classified into four subgroups based on the different experimental methods used. These four are: (1) irradiation creep using stress relaxation methods, (2) creep measurements using pressurized tubes, (3) irradiation creep from constant applied load, and (4) irradiation creep experiments using accelerated particles. The similarity and the differences of the results from these methods are discussed and a summary of important results and suggested areas for research is presented. In brief, the important results relate to the dependence of creep on swelling, temperature, stress state and alloying additions. In each of these areas new results have been presented and new questions have arisen which require further research to answer. 65 references.

Test Result Management in Global Health Settings  

PubMed Central

OVERVIEW Across the globe, the ways in which patients' test results are managed are as varied as the many different types of healthcare systems that manage these data. The outcomes, however, are often not too dissimilar: too many clinically significant test results fall through the cracks. The consequences of not following up test results in a timely manner are serious and often devastating to patients: diagnoses are delayed, treatments are not initiated or altered in time, and diseases progress. In resource-poor settings, test results too commonly get filed away within the paper chart in ways that isolate them and prevent passage to future providers caring for a patient. To make matters worse, the onus to act upon these test results often rests on patients who need to return to the clinic within a specified timeframe in order to obtain their results but who may not have the means or are too ill to do so. Even in more developed healthcare settings that use electronic records, clinical data residing in the electronic medical record (EMR) are often stubbornly “static”—key pieces of clinical information are frequently not recognized, retrieved, or shared easily. In this way, EMRs are not unlike paper record systems, and therefore, EMRs alone will not solve this problem. To illustrate this problem, consider the case of a patient newly diagnosed with HIV in 3 different healthcare delivery settings. PMID:24278831

Predictive aging results in radiation environments  

NASA Astrophysics Data System (ADS)

We have previously derived a time-temperature-dose rate superposition methodology, which, when applicable, can be used to predict polymer degradation versus dose rate, temperature and exposure time. This methodology results in predictive capabilities at the low dose rates and long time periods appropriate, for instance, to ambient nuclear power plant environments. The methodology was successfully applied to several polymeric cable materials and then verified for two of the materials by comparisons of the model predictions with 12 year, low-dose-rate aging data on these materials from a nuclear environment. In this paper, we provide a more detailed discussion of the methodology and apply it to data obtained on a number of additional nuclear power plant cable insulation (a hypalon, a silicone rubber and two ethylene-tetrafluoroethylenes) and jacket (a hypalon) materials. We then show that the predicted, low-dose-rate results for our materials are in excellent agreement with long-term (7-9 year) low-dose-rate results recently obtained for the same material types actually aged under bnuclear power plant conditions. Based on a combination of the modelling and long-term results, we find indications of reasonably similar degradation responses among several different commercial formulations for each of the following "generic" materials: hypalon, ethylene-tetrafluoroethylene, silicone rubber and PVC. If such "generic" behavior can be further substantiated through modelling and long-term results on additional formulations, predictions of cable life for other commercial materials of the same generic types would be greatly facilitated.

Efficient Diversification of Web Search Results  

E-print Network

In this paper we analyze the efficiency of various search results diversification methods. While efficacy of diversification approaches has been deeply investigated in the past, response time and scalability issues have been rarely addressed. A unified framework for studying performance and feasibility of result diversification solutions is thus proposed. First we define a new methodology for detecting when, and how, query results need to be diversified. To this purpose, we rely on the concept of "query refinement" to estimate the probability of a query to be ambiguous. Then, relying on this novel ambiguity detection method, we deploy and compare on a standard test set, three different diversification methods: IASelect, xQuAD, and OptSelect. While the first two are recent state-of-the-art proposals, the latter is an original algorithm introduced in this paper. We evaluate both the efficiency and the effectiveness of our approach against its competitors by using the standard TREC Web diversification track test...

Adaptive structures - Test hardware and experimental results  

NASA Technical Reports Server (NTRS)

The facilities and procedures used at JPL to test adaptive structures such as the large deployable reflector (LDR) are described and preliminary results are reported. The applications of adaptive structures in future NASA missions are outlined, and the techniques which are employed to modify damping, stiffness, and isolation characteristics, as well as geometric changes, are listed. The development of adaptive structures is shown to be effective as a result of new actuators and sensors, and examples are listed for categories such as fiber optics, shape-memory materials, piezoelectrics, and electrorheological fluids. Some ground test results are described for laboratory truss structures and truss test beds, which are shown to be efficient and easy to assemble in space. Adaptive structures are shown to be important for precision space structures such as the LDR, and can alleviate ground test requirements.

Results concerning the centre of our galaxy  

E-print Network

For many years it was felt that, when a star collapsed, a white dwarf resulted if the mass of the original star was below the Chandrasekhar limit, a neutron star if the mass was somewhat larger but still less than four or five solar masses, but after that black holes were felt to provide the only possible final state. The extension of this hierarchy to include the possibility of quark, and even sub-quark, stars has been proposed and here is used to offer an alternative explanation for the recently published photograph, credited to Eckart and Genzel, purporting to show stars near the centre of our Galaxy moving at very high speeds. The same basic results are used also to consider the even more recent results of Schodel and collaborators concerning the detailed observations of a stellar orbit very close to the centre of our galaxy.

New Results on Nucleon Spin Structure  

E-print Network

Recent precision spin structure data from Jefferson Lab have significantly advanced our knowledge of nucleon structure in the valence quark (high-$x$) region and improved our understanding of higher-twist effects, spin sum rules and quark-hadron duality. First, results of a precision measurement of the neutron spin asymmetry, $A_1^n$, in the high-$x$ region are discussed. The new data shows that $A_1^n$ becomes positive at high $x$. They provide crucial input for the global fits to world data to extract polarized parton distribution functions. The up and down quark spin distributions in the nucleon were extracted. The results for $\\Delta d/d$ disagree with the leading-order pQCD prediction assuming hadron helicity conservation. Then, results of a precision measurement of the $g_2^n$ structure function to study higher-twist effects are presented. The data show a clear deviation from the lead-twist contribution. The second moment of the spin structure functions and the twist-3 matrix element $d_2^n$ results were extracted at a high $Q2$ of 5 GeV$^2$. Results for $d_2^n$ at low-to-intermediate $Q2$ from 0.1 to 0.9 GeV$^2$ were also extracted from the JLab data. In the same $Q2$ range, the $Q2$ dependence of the moments of the nucleon spin structure functions was measured, providing a unique bridge linking the quark-gluon picture of the nucleon and the coherent hadronic picture. Sum rules and generalized forward spin polarizabilities were extracted. Finally, preliminary results were presented on the resonance spin structure functions in the $Q2$ range from 1 to 4 GeV$^2$ to study the quark-hadron duality.

NEW RESULTS FROM CRYSTAL COLLIMATION AT RHIC.  

SciTech Connect

In this paper, we discuss new results from the use of the crystal collimator from the 2003 run. The yellow ring of the Relativistic Heavy Ion Collider (RHIC) has a bent crystal collimator. By properly aligning the crystal to the beam halo, particles entering the crystal are deflected away from the beam and intercepted downstream in a copper scraper. The purpose of a bent crystal is to improve the collimation efficiency as compared to a scraper alone. We compare these results to previous data, simulation, and theoretical predictions.

Tunka-133: Results of 3 year operation  

NASA Astrophysics Data System (ADS)

The EAS Cherenkov light array Tunka-133, with ~3 km2 geometric area, is taking data since 2009. The array permits a detailed study of cosmic ray energy spectrum and mass composition in the PeV energy range. After a short description of the methods of EAS parameter reconstruction, we present the all-particle energy spectrum and results of studying CR composition, based on 3 seasons of array operation. In the last part of the paper, we discuss possible interpretations of the obtained results.

Relativity concept inventory: Development, analysis, and results

We report on a concept inventory for special relativity: the development process, data analysis methods, and results from an introductory relativity class. The Relativity Concept Inventory tests understanding of relativistic concepts. An unusual feature is confidence testing for each question. This can provide additional information; for example, high confidence correlated with incorrect answers suggests a misconception. A novel aspect of our data analysis is the use of Monte Carlo simulations to determine the significance of correlations. This approach is particularly useful for small sample sizes, such as ours. Our results show a gender bias that was not present in course assessment, similar to that reported for the Force Concept Inventory.

I summarize the physics results obtained from large-scale dynamical overlap fermion simulations by the JLQCD and TWQCD collaborations. The numerical simulations are performed at a fixed global topological sector; the physics results in the theta-vacuum is reconstructed by correcting the finite volume effect, for which the measurement of the topological susceptibility is crucial. Physics applications we studied so far include a calculation of chiral condensate, pion mass, decay constant, form factors, as well as (vector and axial-vector) vacuum polarization functions and nucleon sigma term.

Hydatidiform mole resulting from sexual violence  

PubMed Central

Background Hydatidiform mole (HM) is characterized by abnormal proliferation of human trophoblast with producers functioning tissues of human chorionic gonadotropin. It can evolve with ovarian cysts tecaluteínicos, hypertension of pregnancy or hyperthyroidism. The incidence of HM is variable and its etiology poorly known, associated with nutritional factors, environmental, age, parity, history of HM, oral contraceptives, smoking, consanguinity or defects in germ cells. There is no reference in literature on HM resulting from sexual violence, objective of this report. Method Description of two cases of HM among 1146 patients with pregnancy resulting from sexual violence treated at Hospital Pérola Byington, São Paulo, from July 1994 to August 2011. Results The cases affected young, white, unmarried, low educated and low parity women. Sexual violence was perpetrated by known offenders unrelated to the victims, under death threat. Ultrasound and CT of the pelvis showed bulky uterus compatible with HM without myometrial invasion. One case was associated with theca lutein cysts. The two cases were diagnosed in the second trimester of pregnancy and evolved with hyperthyroidism. There was no hypertension, disease recurrence, metastasis or sexually transmitted infection. Conclusion The incidence of HM was 1:573 pregnancies resulting from rape, within the range estimated for Latin American countries. Trophoblastic material can be preserved to identify the violence perpetrator, considering only the paternal HM chromosomes. History of sexual violence should be investigated in cases of HM in the first half of adolescence and women in a vulnerable condition. PMID:22353179

Recent Results in Ring-Diagram Analysis  

NASA Astrophysics Data System (ADS)

The ring-diagram technique was developed by Frank Hill 25 years ago and matured quickly during the late 1990s. It is nowadays one of the most commonly used techniques in local helioseismology. The method consists in the power spectral analysis of solar acoustic oscillations on small regions (2° to 30°) of the solar surface. The power spectrum resembles a set of trumpets nested inside each other and for a given frequency, it looks like a ring, hence the technique's name. It provides information on the horizontal flow field and thermodynamic structure in the layers immediately below the photosphere. With data regularly provided by MDI, GONG, and more recently HMI, many important results have been achieved. In recently years, these results include estimations of the meridional circulation and its evolution with solar cycle; flows associated with active regions, as well as, flow divergence and vorticity, and thermal structure beneath and around active regions. Much progress is expected with data now provided by HMI's high spatial resolution observations and high duty cycle. There are two data processing pipelines (GONG and HMI) providing free access to the data and the results of the ring-diagram analysis. Here we will discuss the most recent results and improvements in the technique, as well as, the many challenges that still remain.

In the list of the main items studied by the CERN COMPASS experiment there are the transverse spin and momentum effects visible in the azimuthal distributions of hadrons produced in the deep inelastic scattering. In the years 2002-2004 COMPASS has collected data with a 6LiD target with the polarization oriented transversely with respect to the muon beam direction for about 20% of the running time; in 2007, COMPASS has used for the first time a proton NH_3 target with the data taking time equally shared between longitudinal and transverse polarization of the target. After reviewing the results obtained with the deuteron, the new results for the Collins and Sivers asymmetries of the proton will be presented.

[Carotid surgery, indications, results and perspectives].  

PubMed

A series of 215 patients who had undergone 250 carotid artery operations were followed up for a mean of 30 months. Perioperative mortality was 2%, neurologic morbidity was 7% but with permanent sequelae in 1.39% of cases. Recurrence of stenosis was detected in 0.8% of patients but there were no cases of postoperative thrombosis. Indications for surgery were based on the existence of hemispheric ischemic accidents corresponding to the territory supplied by the artery operated upon, and on anatomic and evolutive arguments drawn from results of non-invasive review examinations: ultrasonography and Doppler. Results obtained: 81.9% of patients were asymptomatic after 30 months, appear to be superior to those of the natural history of carotid artery lesions. PMID:4056617

GRACE Gravity Field Results from JPL  

NASA Astrophysics Data System (ADS)

The GRACE team at the Jet Propulsion Laboratory have over the past few years adapted the MIRAGE software used for deep space tracking data analysis and determination of the gravity field of planetary bodies such as Mars, Venus, the Moon, and 433 Eros, for GRACE applications. We have used this software to produce Earth gravity fields of unprecedented quality from a combination of the first GRACE K/Ka-band intersatellite tracking, GPS, accelerometer, and star camera data. In this paper we will present the results of that gravity field analysis, including the parameterization used, the spectral content of the residuals, the calibrated covariance, and performance in external tests such as orbit fits and sea surface topography. In addition, since the software and parameterization are independent of that used at the University of Texas and GFZ Potsdam, it provides a type of verification of the fields, and we will discuss the results of the intercomparison of the available gravity solutions.

Stuttering is an uncommon presentation of acute stroke. Reported cases have often been associated with left sided cortical lesions, aphasia, and difficulties with other non-linguistic tests of rhythmic motor control. Three patients with subcortical lesions resulting in stuttering are discussed. In one patient the ability to perform time estimations with a computerised repetitive time estimation task was characterised.?One patient had a pontine infarct with clinical evidence of cerebellar dysfunction. A second patient had a left basal ganglionic infarct and a disruption of timing estimation. A third patient had a left subcortical infarct and a mild aphasia.?These findings expand the reported distribution of infarction that can result in acquired stuttering. Subcortical mechanisms of speech control and timing may contribute to the pathophysiology of acquired stuttering.?? PMID:10990523

Genomic Screening with RNAi: Results and Challenges  

PubMed Central

RNA interference (RNAi) is an effective tool for genome-scale, high-throughput analysis of gene function. In the past five years, a number of genome-scale RNAi high-throughput screens (HTSs) have been done in both Drosophila and mammalian cultured cells to study diverse biological processes, including signal transduction, cancer biology, and host cell responses to infection. Results from these screens have led to the identification of new components of these processes and, importantly, have also provided insights into the complexity of biological systems, forcing new and innovative approaches to understanding functional networks in cells. Here, we review the main findings that have emerged from RNAi HTS and discuss technical issues that remain to be improved, in particular the verification of RNAi results and validation of their biological relevance. Furthermore, we discuss the importance of multiplexed and integrated experimental data analysis pipelines to RNAi HTS. PMID:20367032

An Overview of Recent Results from CLAS  

SciTech Connect

The unique capabilities of the CLAS detector to measure exclusive meson electroproduction off protons, with almost complete coverage of the final hadron phase space, has extended our knowledge of excited baryon structure. Consistent results from Np and Npp final states provide convincing evidence for reliable extraction of N* electrocouplings. Theoretical analyses of these results, using self-consistent dynamical calculations using an internal quark core and an external meson-baryon cloud suggest that meson-baryon dressing amplitudes need to be included. The meson-baryon dressing was already shown to be necessary to get agreement between calculations and data on the D resonance transition magnetic moment at low Q{sup 2}. Similarly, a new measurement of the transition magnetic moment for strange baryons also disagrees with quark models, suggesting the need for meson-baryon dressings. In the near future, the CLAS detector will be replaced with CLAS12, providing new high-precision data.

Viking magnetic properties experiment - Extended mission results  

NASA Technical Reports Server (NTRS)

The backhoe magnets on Viking Lander (VL) 2 were successfully cleaned, followed by a test involving successive insertions of the cleaned backhoe into the surface. Rapid saturation of the magnets confirmed evidence from primary mission results that the magnetic mineral in the Martian surface is widely distributed, most probably in the form of composite particles of magnetic and nonmagnetic minerals. An image of the VL 2 backhoe taken via the X4 magnifying mirror demonstrates the fine-grained nature of the attracted magnetic material. The presence of maghemite and its occurrence as a pigment in, or a thin coating on, all mineral particles or as discrete, finely divided and widely distributed crystallites, are consistent with data from the inorganic analysis experiments and with laboratory simulations of results of the biology experiments on Mars.

Viking magnetic properties investigation - Further results  

NASA Technical Reports Server (NTRS)

The amounts of magnetic particles held on the reference test chart and backhoe magnets on lander 2 and lander 1 are comparable, indicating the presence of an estimated 3 to 7 percent by weight of relatively pure, strongly magnetic particles in the soil at the lander 2 sampling site. Preliminary spectrophotometric analysis of the material held on the backhoe magnets on lander 1 indicates that its reflectance characteristics are indistinguishable from material within a sampling trench with which it has been compared. The material on the RTC magnet shows a different spectrum, but it is suspected that the difference is the result of a reflectance contribution from the magnesium metal covering on the magnet. It is argued that the results indicate the presence, now or originally, of magnetite, which may be titaniferous.

Performance results for a hybrid coding system.  

NASA Technical Reports Server (NTRS)

Results of computer simulation studies of the hybrid pull-up bootstrap decoding algorithm, using a constraint length 24, nonsystematic, rate 1/2 convolutional code for the symmetric channel with both binary and eight-level quantized outputs. Computational performance was used to measure the effect of several decoder parameters and determine practical operating constraints. Results reveal that the track length may be reduced to 500 information bits with small degradation in performance. The optimum number of tracks per block was found to be in the range from 7 to 11. An effective technique was devised to efficiently allocate computational effort and identify reliably decoded data sections. Long simulations indicate that a practical bootstrap decoding configuration has a computational performance about 1.0 dB better than sequential decoding and an output bit error rate about .0000025 near the R sub comp point.

Then we will review the latest results for nucleus-nucleus collisions from RHIC, and together with the baseline results from d+A and p+p collisions, discuss several alternative explanations for the observed suppressions and future prospects for distinguishing these different pictures.

Results of the central data analysis.  

PubMed Central

This chapter presents the results of blind serological studies carried out by workshop participants on 87 monoclonal antibodies (mAbs) supplied to them as a coded panel. Twenty six mAbs had been studied in the first workshop. Participants were asked to carry out immunohistochemical, immunocytological or flow cytometric analysis on a mandatory panel of target tissues or cells. Central computer analysis and other supporting data allowed the assignment of 33 mAbs to seven clusters. Two of the antigens identified have been cloned while two more have been defined as carbohydrate epitopes. The results allow comparison of new mAbs against lung cancer with existing ones and are beginning to provide a description of the antigenic structure of the SCLC cell surface. PMID:1645565

More results on oscillating edge-flames  

SciTech Connect

We examine a simple model of a side-anchored non-premixed edge-flame in order to gain insights into the oscillations that are sometimes observed in microgravity candle burning, flame-spread over liquids, etc. Previous results describe the role played by the Lewis number of the fuel, and the Damkoehler number, and here we examine both the effects of an on-edge and off-edge convective flow, and the effects of a heat sink. The on-edge flow and the heat sink tend to destabilize and the off-edge flow tends to stabilize, results consistent with our hypothesis regarding the genesis of the oscillations.

Overview of Athena Microscopic Imager Results  

NASA Technical Reports Server (NTRS)

The Athena science payload on the Mars Exploration Rovers (MER) includes the Microscopic Imager (MI). The MI is a fixed-focus camera mounted on an extendable arm, the Instrument Deployment Device (IDD). The MI acquires images at a spatial resolution of 31 microns/pixel over a broad spectral range (400 - 700 nm). The MI uses the same electronics design as the other MER cameras but its optics yield a field of view of 32 32 mm across a 1024 1024 pixel CCD image. The MI acquires images using only solar or skylight illumination of the target surface. The MI science objectives, instrument design and calibration, operation, and data processing were described by Herkenhoff et al. Initial results of the MI experiment on both MER rovers (Spirit and Opportunity) have been published previously. Highlights of these and more recent results are described.

First results with the Microball and Gammasphere  

SciTech Connect

The Microball, an improved 4{pi} multi-detector array, was used recently in conjunction with Gammasphere in three experiments. Highlights of the first results are presented here. The Microball consists of 95 CsI(T{ell}) scintillation detectors with individual Si photodiode readout, arranged in 9 rings. In these first experiments the Microball performed as designed, but the results in new physics exceeded the authors` expectations. They can say with certainty that by its powerful channel selection the Microball enhanced the performance of Gammasphere by one full coincidence fold. This was possible for all exit channels involving charged particle emission, with increasing performance benefit as one progressed to lighter reaction systems. They summarize the essential characteristics of the Microball and give some performance benchmarks. A detailed description of the Microball is given.

CA Testing Workshops: Process, Issues, Results  

NASA Technical Reports Server (NTRS)

This presentation will describe the organization and conduct of the workshops, list the topics discussed, and conclude with a more-detailed examination of a related set of issues dear to the presenters heart. Because the current HSCT configuration is expected to have (mostly) turbulent flow over the wings, and because current CFD predictions assume fully-turbulent flow, the wind tunnel testing to date has attempted to duplicate this condition at the lower Reynolds numbers attainable on the ground. This frequently requires some form of artificial boundary layer trip to induce transition near the wing's leading edge. But this innocent-sounding goal leads to a number of complications, and it is not clear that present-day testing technology is adequate to the task. An description of some of the difficulties, and work underway to address them, forms the "Results" section of this talk. Additional results of the testing workshop will be covered in presentations by other team members.

Verifying Search Results Over Web Collections  

E-print Network

Searching accounts for one of the most frequently performed computations over the Internet as well as one of the most important applications of outsourced computing, producing results that critically affect users' decision-making behaviors. As such, verifying the integrity of Internet-based searches over vast amounts of web contents is essential. We provide the first solution to this general security problem. We introduce the concept of an authenticated web crawler and present the design and prototype implementation of this new concept. An authenticated web crawler is a trusted program that computes a special "signature" $s$ of a collection of web contents it visits. Subject to this signature, web searches can be verified to be correct with respect to the integrity of their produced results. This signature also allows the verification of complicated queries on web pages, such as conjunctive keyword searches. In our solution, along with the web pages that satisfy any given search query, the search engine also ...

First astrophysical results from AMBER/VLTI  

E-print Network

The AMBER instrument installed at the Very Large Telescope (VLT) combines three beams from as many telescopes to produce spectrally dispersed fringes from milli-arcsecond angular scale in the near infrared. Two years after installation, first scientific observations have been carried out during the Science Demonstration Time and the Guaranteed Time mostly on bright sources due to some VLTI limitations. In this paper, we review these first astrophysical results and we show which types of completely new information is brought by AMBER. The first astrophysical results have been mainly focusing on stellar wind structure, kinematics, and its interaction with dust usually concentrated in a disk. Because AMBER has dramatically increased the number of measures per baseline, this instrument brings strong constraints on morphology and models despite a relatively poor (u, v) coverage for each object.

New results on muon radiative decay  

NASA Astrophysics Data System (ADS)

The PIBETA and PEN experiments, a series of precise measurements of rare pion and muon decays at PSI, have acquired a substantial set of &+circ;->e^+ ?? ?, radiative muon decay (RMD), events. The measurements were made using a stopped pion beam decaying in an active target, and positron and photon detection in a segmented spherical pure-CsI electromagnetic shower calorimeter covering ??˜3? sr, with MWPC central tracking and particle identification. The present RMD study has resulted in approximately 30-fold improvement in the precision of the decay branching ratio for (E?> 10 MeV, and ??-e> 30^o), compared to previous work. Our 1% result is in excellent agreement with standard model theoretical predictions. Focusing on a narrower range of phase space, we were able to improve significantly the upper limit on the Michel paramter ?, which is sensitive to non-(V-A) admixtures in the weak lagrangian.

Simulation results for the Viterbi decoding algorithm  

NASA Technical Reports Server (NTRS)

Concepts involved in determining the performance of coded digital communications systems are introduced. The basic concepts of convolutional encoding and decoding are summarized, and hardware implementations of sequential and maximum likelihood decoders are described briefly. Results of parametric studies of the Viterbi decoding algorithm are summarized. Bit error probability is chosen as the measure of performance and is calculated, by using digital computer simulations, for various encoder and decoder parameters. Results are presented for code rates of one-half and one-third, for constraint lengths of 4 to 8, for both hard-decision and soft-decision bit detectors, and for several important systematic and nonsystematic codes. The effect of decoder block length on bit error rate also is considered, so that a more complete estimate of the relationship between performance and decoder complexity can be made.

SLS-1 flight experiments preliminary significant results  

NASA Technical Reports Server (NTRS)

Spacelab Life Sciences-1 (SLS-1) is the first of a series of dedicated life sciences Spacelab missions designed to investigate the mechanisms involved in the physiological adaptation to weightlessness and the subsequent readaptation to 1 gravity (1 G). Hypotheses generated from the physiological effects observed during earlier missions led to the formulation of several integrated experiments to determine the underlying mechanisms responsible for the observed phenomena. The 18 experiments selected for flight on SLS-1 investigated the cardiovascular, cardiopulmonary, regulatory physiology, musculoskeletal, and neuroscience disciplines in both human and rodent subjects. The SLS-1 preliminary results gave insight to the mechanisms involved in the adaptation to the microgravity environment and readaptation when returning to Earth. The experimental results will be used to promote health and safety for future long duration space flights and, as in the past, will be applied to many biomedical problems encountered here on Earth.

Validation Results for LEWICE 3.0  

NASA Technical Reports Server (NTRS)

A research project is underway at NASA Glenn to produce computer software that can accurately predict ice growth under any meteorological conditions for any aircraft surface. This report will present results from version 3.0 of this software, which is called LEWICE. This version differs from previous releases in that it incorporates additional thermal analysis capabilities, a pneumatic boot model, interfaces to computational fluid dynamics (CFD) flow solvers and has an empirical model for the supercooled large droplet (SLD) regime. An extensive comparison of the results in a quantifiable manner against the database of ice shapes and collection efficiency that have been generated in the NASA Glenn Icing Research Tunnel (IRT) has also been performed. The complete set of data used for this comparison will eventually be available in a contractor report. This paper will show the differences in collection efficiency between LEWICE 3.0 and experimental data. Due to the large amount of validation data available, a separate report is planned for ice shape comparison. This report will first describe the LEWICE 3.0 model for water collection. A semi-empirical approach was used to incorporate first order physical effects of large droplet phenomena into icing software. Comparisons are then made to every single element two-dimensional case in the water collection database. Each condition was run using the following five assumptions: 1) potential flow, no splashing; 2) potential flow, no splashing with 21 bin drop size distributions and a lift correction (angle of attack adjustment); 3) potential flow, with splashing; 4) Navier-Stokes, no splashing; and 5) Navier-Stokes, with splashing. Quantitative comparisons are shown for impingement limit, maximum water catch, and total collection efficiency. The results show that the predicted results are within the accuracy limits of the experimental data for the majority of cases.

Cassini radar : system concept and simulation results  

NASA Astrophysics Data System (ADS)

The Cassini mission is an international venture, involving NASA, the European Space Agency (ESA) and the Italian Space Agency (ASI), for the investigation of the Saturn system and, in particular, Titan. The Cassini radar will be able to see through Titan's thick, optically opaque atmosphere, allowing us to better understand the composition and the morphology of its surface, but the interpretation of the results, due to the complex interplay of many different factors determining the radar echo, will not be possible without an extensive modellization of the radar system functioning and of the surface reflectivity. In this paper, a simulator of the multimode Cassini radar will be described, after a brief review of our current knowledge of Titan and a discussion of the contribution of the Cassini radar in answering to currently open questions. Finally, the results of the simulator will be discussed. The simulator has been implemented on a RISC 6000 computer by considering only the active modes of operation, that is altimeter and synthetic aperture radar. In the instrument simulation, strict reference has been made to the present planned sequence of observations and to the radar settings, including burst and single pulse duration, pulse bandwidth, pulse repetition frequency and all other parameters which may be changed, and possibly optimized, according to the operative mode. The observed surfaces are simulated by a facet model, allowing the generation of surfaces with Gaussian or non-Gaussian roughness statistic, together with the possibility of assigning to the surface an average behaviour which can represent, for instance, a flat surface or a crater. The results of the simulation will be discussed, in order to check the analytical evaluations of the models of the average received echoes and of the attainable performances. In conclusion, the simulation results should allow the validation of the theoretical evaluations of the capabilities of microwave instruments, when considering topics like the surface topography, stratigraphy and identification of different materials.

Spacelab Science Results Study: Executive Summary  

NASA Technical Reports Server (NTRS)

Beginning with OSTA-1 in November 1981, and ending with Neurolab in March 1998, thirty-six shuttle missions are considered Spacelab missions because they carried various Spacelab components such as the Spacelab module, the pallet, the Instrument Pointing System (IPS), or the MPESS. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the United States, Europe, and Japan. These experiments resulted in several thousand papers published In refereed journals, and thousands more in conference proceedings, chapters in books, and other publications. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and, if appropriate, where the knowledge they produced has been applied.

Damage to DNA Resulting from Ionizing Radiation  

NASA Astrophysics Data System (ADS)

This work studies the mechanism by which radiation causes biological damage. In general, radiation leads to ionized molecules in solution, which can produce free radical molecules through a series of chemical reactions. These free radicals can chemically attack the DNA molecule resulting in breaks in the phosphate-sugar backbone of the molecule. The molecule may break into smaller pieces or recombine into different shapes. If the molecule were in a living cell, such damage would most likely lead to cell death. This work involves irradiating extra-cellular, non-living DNA plasmid in solution and assessing the amount of damage done to the plasmid. After irradiating the vials at various high doses ( 0.05-10 Gy), the resulting DNA fragments were analyzed via gel electrophoresis. We can therefore look at the fraction of the sample that is still intact compared to the smaller pieces that have resulted from radiation-induced strand breaks in the DNA. A better understanding of radiation and its ability to damage DNA (and kill cells) may lead to improved methods for radiation therapy. (This work was possible through the cooperation and assistance from the staff and facilities at Carolinas Hospital in Florence, SC.)

Solid Surface Combustion Experiment: Thick Fuel Results  

NASA Technical Reports Server (NTRS)

The results of experiments for spread over polymethylmethacrylate, PMMA, samples in the microgravity environment of the Space Shuttle are described. The results are coupled with modelling in an effort to describe the physics of the spread process for thick fuels in a quiescent, microgravity environment and uncover differences between thin and thick fuels. A quenching phenomenon not present for thin fuels is delineated, namely the fact that for thick fuels the possibility exists that, absent an opposing flow of sufficient strength to press the flame close enough to the fuel surface to allow the heated layer in the solid to develop, the heated layer fails to become 'fully developed.' The result is that the flame slows, which in turn causes an increase in the relative radiative loss from the flame, leading eventually to extinction. This potential inability of a thick fuel to develop a steady spread rate is not present for a thin fuel because the heated layer is the fuel thickness, which reaches a uniform temperature across the thickness relatively rapidly.

Review of sodium analysis proficiency test results.  

PubMed

Proficiency testing results for sodium analysis in foods raised concerns over the proportion of laboratories achieving satisfactory z-scores. Test materials for sodium analysis include fruit juice, canned meat meal, tomato sauce, cheese and pasta meal, and snack food. Fruit juice and tomato sauce data sets are the most problematic in deriving the assigned value with sufficiently low uncertainty to provide evaluative z-scores. The standard deviation for proficiency is derived from Horwitz, with a lack of collaborative trial data for these matrices to provide other guidance. The status of accreditation for the method/matrix does not appear to influence the observed variation in results. Microwave digestion is much less commonly used than simple acid digestion. The choice of determination method appears to be entirely matrix dependent (whether flame atomic absorption spectroscopy, flame photometry or inductively coupled plasma spectroscopy). Results for juice matrix may be overestimated if flame photometry is used, due to either potassium interference or careless reporting where potassium is also determined. PMID:21240823

Computational results for parallel unstructured mesh computations  

SciTech Connect

The majority of finite element models in structural engineering are composed of unstructured meshes. These unstructured meshes are often very large and require significant computational resources; hence they are excellent candidates for massively parallel computation. Parallel solution of the sparse matrices that arise from such meshes has been studied heavily, and many good algorithms have been developed. Unfortunately, many of the other aspects of parallel unstructured mesh computation have gone largely ignored. The authors present a set of algorithms that allow the entire unstructured mesh computation process to execute in parallel -- including adaptive mesh refinement, equation reordering, mesh partitioning, and sparse linear system solution. They briefly describe these algorithms and state results regarding their running-time and performance. They then give results from the 512-processor Intel DELTA for a large-scale structural analysis problem. These results demonstrate that the new algorithms are scalable and efficient. The algorithms are able to achieve up to 2.2 gigaflops for this unstructured mesh problem.

Radiation Belt Electron Loss mechanisms: New results  

NASA Astrophysics Data System (ADS)

The radiation belt electron precipitation (RBEP) into the topside ionosphere is a phenomenon which is known for several decades. However, the radiation belt source and loss mechanisms have not still well understood, including PBEP. Here we present the results of a systematic study of RBEP observations, as obtained from the satellite DEMETER and the series of POES satellites, in comparison with variation of seismic activity. We found that this type of RBEP bursts present special characteristics in the inner region of the inner radiation belt before large (M>7, or even M>5) earthquakes (EQs), as for instance characteristic (a) flux-time profiles, (b) energy spectrum, (c) electron flux temporal evolution, (d) spatial distributions and (e) they are associated with broad band VLF activity, some days before an EQ. The RBEP before EQs appears, not only as a burst, but as an increase of the normal electron background flux in large range of latitudes during magnetospheric storms. Recent results, in the presence of a magnetospheric storm and of strong seismic activity, seem to suggest an increase of the normal flux in the slot region as well. We found significant evidence that, among EQs-lightings-Earth based transmitters, seismic activity is that agent which probably make the main contribution to the RBEP at middle latitudes. Further research is in progress in order to further test the present results.

Prostate elastography: preliminary in vivo results  

NASA Astrophysics Data System (ADS)

We report preliminary results from our investigation of in vivo prostate elastography. Fewer than 50% of all prostate cancers are typically visible in current clinical imaging modalities. Elastography displays a map of strain that results when tissue is externally compressed. Thus, elastography is ideal for imaging prostate cancers because they are generally stiffer than the surrounding tissue and stiffer regions usually exhibit lower strain in elastograms. In our study, digital radio-frequency (RF) ultrasound echo data were acquired from prostate-cancer patients undergoing brachytherapy. Seed placement is guided by a transrectal ultrasound (TRUS) probe, which is held in a mechanical fixture. The probe can be moved in XYZ directions and tilted. The probe face, in contact with the rectal wall, is used to apply a compression force to the immediately adjacent prostate. We also used a water-filled (acoustic) coupling balloon to compress the prostate by increasing the water volume inside the balloon. In each scan plane (transverse), we acquired RF data from successive scans at the scanner frame rate as the deformation force on the rectal wall was continuously increased. We computed strain using 1D RF cross-correlation analysis. The compression method based on fixture displacement produced low-noise elastograms that beautifully displayed the prostate architecture and emphasized stiff areas. Balloon-based compression also produced low-noise elastograms. Initial results demonstrate that elastography may be useful in the detection and evaluation of prostate cancers, occult in conventional imaging modalities.

Recent Results From CLEO-c  

E-print Network

This paper describes recent preliminary results from the CLEO-c experiment using an initial ~60 pb^-1 sample of data collected in e^+e^- collisions at a center of mass energy around the mass of the psi(3770). A first measurement of the branching fraction BR(D^+ -> mu^+ nu) = (3.5 +/- 1.4 +/- 0.6)x 10^-4 and the corresponding decay constant f_D = (202 +/- 41 +/- 17) MeV has been made. Several charged and neutral D meson absolute exclusive semileptonic branching fractions have been measured, including first measurements of the branching fractions BR(D^0 -> rho^-e^+ nu) = (0.19 +/- 0.04 +/- 0.02)% and BR(D^+ -> omega e^+ nu) = (0.17 +/- 0.006 +/- 0.01)%. Estimated uncertainties for inclusive D semileptonic decay modes are also presented. Fits to single and double D tagged events are used to extract absolute branching fractions of several hadronic D decay modes and DDbar production cross sections. Most of these results from this small preliminary sample are already of greater sensitivity than previously published results.

Pore destruction resulting from mechanical thermal expression  

SciTech Connect

Mechanical thermal expression (MTE) is a dewatering technology ideally suited for the dewatering of internally porous biomaterials. For such materials, the combined application of temperature and compressive force in the MTE process enhances the collapse of the porous structure, resulting in effective water removal. In this article, a comparison of the dewatering of titanium dioxide, which is an ideal incompressible, non-porous material, and lignite, which is a porous plant-based biomaterial, is presented. The comparison is based on the parameters critical to dewatering, namely the material compressibility and the permeability. With the aid of mercury porosimetry results, a detailed discussion of the pore destruction of lignite resulting from MTE processing is presented. It is illustrated that there is a well-defined relationship between the pore size distribution after MTE dewatering and the MTE temperature and pressure. The discussion is extended to an investigation of the effects of MTE processing conditions on the effective and noneffective porosity. The effective porosity is defined as the interconnected porosity, which contributes to flow through the compressed matrix, while the non-effective porosity is the remaining porosity, which does not contribute to flow. It is illustrated that there is a linear relationship in both the effective and non-effective porosity with the total porosity. The linear relationship is independent of the processing conditions. It is also shown that MTE processing collapses the effective and non-effective pores at roughly the same rate.

IMPROVED RESULTS FOR STACKELBERG SCHEDULING STRATEGIES.  

SciTech Connect

We continue the study initiated in [Ro01] on Stackelberg Scheduling Strategies. We are given a set of n independent parallel machines or equivalently a set of n parallel edges on which certain flow has to be sent. Each edge e is endowed with a latency function l{sub e}({center_dot}). The setting is that of a non-cooperative game: players choose edges so as minimize their individual latencies. Additionally, there is a single player who control as fraction ?? of the total flow. The goal is to find a strategy for the leader (i.e. an assignment of flow to indivual links) such that the selfish users react so as to minimize the total latency of the system. Building on the recent results in [Ro01, RT00], we show the following: 1. We devise a fully polynomial approximate scheme for the problem of finding the cheapest Stackelberg Strategy: given a performance requirement, our algorithm runs in time polynomial in n and {var_epsilon} and produces a Stackelberg strategy s, whose associated cost is within a 1 + {var_epsilon} factor of the optimum stackelberg strategy s*. The result is extended to obtain a polynomial-approximation scheme when instances are restricted to layered directed graphs in which each layer has a bounded number of vertices. 2. We then consider a two round Stackelberg strategy (denoted 2SS). In this strategy, the game consists of three rounds: a move by the leader followed by the moves of all the followers folowed again by a move by the leader who possibly reassigns some of the flows. We show that 2SS always dominates the one round scheme, and for some classes of latency functions, is guaranteed to be closer to the global social optimum. We also consider the variant where the leader plays after the selfish users have routed themselves, and observe that this dominates the one-round scheme. Extensions of the results to the special case when all the latency functions are linear are also presented. Our results extend the earlier results and answer an open question posed by Roughgarden [Ro01].

[Results of 30 keratoprostheses with retrocorneal fixation].  

PubMed

Keratoprosthesis is the last solution for corneally blind patients who cannot benefit from corneal grafts. The indications are limited to blind patients with monophthalmia and bilateral problems that are otherwise untreatable. After implanting the Choyce and Strampelli's devices for more than 10 years, we abandoned these anterior fixation techniques and now use a keratoprosthesis in which the sole mechanical fixation consists of a posterior support which is subsequently sealed by the fibrosis produced by the endothelial-Descement tissues. This new prosthesis is made of two pieces, an optic and an haptic fashioned out of CQ-PMMA. To minimize expulsion, the haptic outer diameter is greater than the central corneal orifice through which the optic is inserted and screwed into the haptic. The keratoprosthesis refractive power can be easily adjusted after lensectomy by changing the 40 D for a 63 D optic. The prosthesis is implanted in a single step surgical procedure, and can be implanted in phakic eyes while respecting the physiology and anatomy of these fragile eyes. This single step procedure reduces the usual repeated operations required when using, other techniques. We operated 12 cases of pseudopemphigus, 9 cases of burns, 7 cases of trachoma, and 2 cases of pseudophakic oedema with good cosmetic and visual results with a follow-up ranging from several months to more than 3 years. The results obtained with this new keratoprosthesis are encouraging. The results have been analysed and classified into: anatomic and functional success 20 cases, anatomic success and functional failures 4 cases, anatomic failures 6 cases. PMID:8282949

Results from Four Years of Venus Express  

NASA Astrophysics Data System (ADS)

Since arriving at Venus in April 2006 Venus Express has provided a wealth of information on a large variety of topics on the atmosphere, surface and plasma environment of the planet. The atmosphere in the southern hemisphere has been studied in detail by three instruments dedicated to atmospheric investigations, from the near IR to the UV and additional information has been derived from radio science measurements. The structure and composition of the atmosphere has been mapped in three dimensions from 40 km to 140 km altitude. Significant temporal and spatial variations have been found, both in composition, density and temperature. Imaging in the UV has revealed strong latitudinal variations and significant temporal changes in the global cloud top morphology as well as identification of various types of waves in the cloud layer. The cloud top altitude varies from about 72 km in the low and middle latitudes to about 64 km in the polar region, marking vast polar depressions, likely a result of the Hadley-type meridional circulation. A large amount of data on the atmospheric circulation has been collected and results include maps of wind speeds at different altitudes and movies of the dynamics of the southern polar vortex. A surface temperature map and an emissivity map of the full southern hemisphere have been constructed from IR images in the spectral windows. By correlating these results and the Magellan radar images and gravity data, regions of young unweathered surfaces likely due to recent volcanism have been identified. The induced magnetosphere with its boundaries and the escape of planetary matter have been characterized by a magnetometer and an energetic particle instrument, and escape rates of hydrogen, oxygen and helium have been determined.A decision to extend the mission until end 2014 is expected at the end of this year.

Beijing MST radar: Overview and preliminary results  

NASA Astrophysics Data System (ADS)

As one of the main facilities of so-called China Meridian Project which is focusing on the monitoring solar-terrestrial link and space weather, as well as sun-earth climate connection study, Beijing MST radar has been completed in the middle of 2011 and started its quasi-continuous operational observation since the end of 2011. Beijing MST radar is located in IAP's field observatory (39.4 N,117.0 E) which is a large scale full coherent VHF Doppler radar, with antenna area 9,110 m^2, power-aperture product 3.1×108 W.m^2. It's antenna array is consisted of 24×24 three element YAGI antenna with square digital active phased array, with beam width equal to or less than 4.5 degree and active five antenna beam azimuth directions and zenith angle ranging from zenith to 20 degree with 1 degree steps. Also the radar uses direct digital receivers and high speed signal processing system. The expected observation altitude is 3-25 km and 60-90 km, for which low, middle and high observation modes can be selected with different vertical resolutions. Same as other MST radars worldwide, Beijing MST radar may observe the 3D wind, backscattering power, and signal noise ratio, for different altitude ranges. Based on preliminary observation in certain time periods, results have been shown that both wind profiling from 3-25 km and 60-90 km are observed. Preliminary results show that the present radar can observe the altitude of lower thermosphere, at least in 90-100 km, even to 110 km. Further results will be given.

Previrialization: Perturbative and N-Body Results  

E-print Network

We present a series of N-body experiments which confirm the reality of the previrialization effect. We also use weakly nonlinear perturbative approach to study the phenomenon. These two approaches agree when the rms density contrast, $\\sigma$, is small; more surprisingly, they remain in agreement when $\\sigma \\approx 1$. When the slope of the initial power spectrum is $n>-1$, nonlinear tidal interactions slow down the growth of density fluctuations and the magnitude of the suppression increases when $n$ (i.e. the relative amount of small scale power) is increased. For $n<-1$ we see an opposite effect: the fluctuations grow more rapidly than in linear theory. The transition occurs at $n=-1$ when the weakly nonlinear correction to $\\sigma$ is close to zero and the growth rate is close to linear. Our results resolve recent controversy between two N-body studies of previrialization. Peebles (1990) assumed $n=0$ and found strong evidence in support of previrialization, while Evrard \\& Crone (1992), who assumed $n=-1$, reached opposite conclusions. As we show here, the initial conditions with $n=-1$ are rather special because the nonlinear effects nearly cancel out for that particular spectrum. In addition to our calculations for scale-free initial spectra, we show results for a more realistic spectrum of Peacock \\& Dodds (1994). Its slope near the scale usually adopted for normalization is close to $-1$, so $\\sigma$ is close to linear. Our results retroactively justify linear normalization at 8$h^{-1}$ Mpc, while also demonstrating the danger and limitations of this practice.

Quantitative results from the focusing schlieren technique  

NASA Technical Reports Server (NTRS)

An iterative theoretical approach to obtain quantitative density data from the focusing schlieren technique is proposed. The approach is based on an approximate modeling of the focusing action in a focusing schlieren system, and an estimation of an appropriate focal plane thickness. The theoretical approach is incorporated in a computer program, and results obtained from a supersonic wind tunnel experiment evaluated by comparison with CFD data. The density distributions compared favorably with CFD predictions. However, improvements to the system are required in order to reduce noise in the data, to improve specifications of a depth of focus, and to refine the modeling of the focusing action.

They showed that if e is the distance to the closest tree metric under the L{sub {infinity}} norm. i.e., e = min{sub T} [L{sub {infinity}} (T-D)], then it is possible to construct a tree T such that L{sub {infinity}} (T-D) {le} 3e, that is, they gave a 3-approximation algorithm for this problem.

Three permanent-magnet arrays are aboard the Viking lander. By sol 35, one array, fixed on a photometric reference test chart on top of the lander, has clearly attracted magnetic particles from airborne dust; two other magnet arrays, one strong and one weak, incorporated in the backhoe of the surface sampler, have both extracted considerable magnetic mineral from the surface as a result of nine insertions associated with sample acquisition. The loose Martian surface material around the landing site is judged to contain 3 to 7 per cent highly magnetic mineral which, pending spectrophotometric study, is thought to be mainly magnetite.

Synergistic exploration: a team approach brings results  

SciTech Connect

Within the last century, exploration techniques have evolved from an emphasis on the anticlinal theory to the increased use of geophysical mapping, modeling an analysis, along with increased use of petrophysical data for reservoir identification. This change in emphasis has necessitated the use of a variety of specialists in a task force approach, as opposed to the one or two person exploration approach used in prior years. This study details why a team, or synergistic, approach to exploration has evolved, and what results such an approach has and will have in terms of reserves found by both the large and small company.

The formal uncertainties of UT1, polar motion, and nutation offsets derived from these experiments are better than the corresponding uncertainties from NEOS-A experiments by a factor of 1.3-2. Baseline length repeatability for the series of 32 experiments over a period of one year is about 0.9 ppb. For comparison, NEOS-A length repeatability is about 1.4 ppb. We will discuss optimal use of Mark 4 in the design of future observing networks.

These measurements are also unified in the fact that their results are often dominated by systematic uncertainties. This review necessarily covers only a limited subset of non-accelerator experiments, and will concentrate on the experimental areas where there has been significant recent progress.

Results of Ukrain monotherapy of prostate cancer.  

PubMed

This study included 15 patients with newly diagnosed prostate cancer with an average age of 71 years (62-85 years). The patients received Ukrain at a total dose of 100 mg (10 mg intravenously every second day, 10 injections altogether). After two to three injections of Ukrain, all the patients noted considerable subjective improvements in their state. Ukrain increased the amount of total T-lymphocytes, including "active" T-lymphocytes, decreased the content of T-suppressors and increased that of T helpers, correspondingly raising the T helper/T-suppressor ratio. Our results undoubtedly indicate the efficacy of Ukrain in the treatment of prostate cancer. PMID:11345026

Wide Area Wind Field Monitoring Status & Results  

SciTech Connect

Volume-scanning elastic has been investigated as a means to derive 3D dynamic wind fields for characterization and monitoring of wind energy sites. An eye-safe volume-scanning lidar system was adapted for volume imaging of aerosol concentrations out to a range of 300m. Reformatting of the lidar data as dynamic volume images was successfully demonstrated. A practical method for deriving 3D wind fields from dynamic volume imagery was identified and demonstrated. However, the natural phenomenology was found to provide insufficient aerosol features for reliable wind sensing. The results of this study may be applicable to wind field measurement using injected aerosol tracers.

This paper presents the results of the adaptive feedforward system in use on the Ground Test Accelerator (GTA). The adaptive feedforward system was shown to correct repetitive, high-frequency errors in the amplitude and phase of the RF field of the pulsed accelerator. The adaptive feedforward system was designed as an augmentation to the RF field feedback control system and was able to extend the closed-loop bandwidth and disturbance rejection by a factor of ten. Within a second implementation, the adaptive feedforward hardware was implemented in place of the feedback control system and was shown to negate both beam transients and phase droop in the klystron amplifier.

Results of adaptive feedforward on GTA  

SciTech Connect

This paper presents the results of the adaptive feedforward system in use on the Ground Test Accelerator (GTA). The adaptive feedforward system was shown to correct repetitive, high-frequency errors in the amplitude and phase of the RF field of the pulsed accelerator. The adaptive feedforward system was designed as an augmentation to the RF field feedback control system and was able to extend the closed-loop bandwidth and disturbance rejection by a factor of ten. Within a second implementation, the adaptive feedforward hardware was implemented in place of the feedback control system and was shown to negate both beam transients and phase droop in the klystron amplifier.

Percutaneous renal puncture: requirements and preliminary results  

E-print Network

This paper introduces the principles of computer assisted percutaneous renal puncture, that would provide the surgeon with an accurate pre-operative 3D planning on CT images and, after a rigid registration with space-localized echographic data, would help him to perform the puncture through an intuitive 2D/3D interface. The whole development stage relied on both CT and US images of a healthy subject. We carried out millimetric registrations on real data, then guidance experiments on a kidney phantom showed encouraging results.

Results of boron-aluminum thrust structure  

NASA Technical Reports Server (NTRS)

Results are presented of testing-to-failure a two member boron-aluminum thrust structure. The structure represented one section of a more complex planar truss and was designed to test the integrity of a diffusion bonded joint. The structure failed at 107 percent of the ultimate design load in the diffusion bond region. Strain gages and displacement transducers were used to measure loads and deflections of the truss. The experimentally derived axial loads, bending moments, and torsion in the various members are presented and compared with predicted values.

The Last Results from the Finuda Experiment  

NASA Astrophysics Data System (ADS)

FINUDA was a complex magnetic spectrometer installed on the DA?NE e+e- collider, the Italian ?-factory put in operation at the INFN National Laboratories of Frascati, near Rome. It was carefully designed and specially dedicated to an extensive program of hypernuclear physics, mainly focussed on spectroscopy of light ?-hypernuclei and on systematic study of their decay modes. Among the latest FINUDA results, of particular importance are the first observation of the neutron-rich ?-hypernucleus 6? H and the first experimental evidence of the so-called hypernucleus two-nucleon induced non-mesonic weak decay.

Landsat/4/Global Positioning System navigation results  

NASA Technical Reports Server (NTRS)

An experimental GPSPAC flown on the Landsat-4 spacecraft was the first spaceborne navigation system to use the NAVSTAR Global Position System (GPS). In order to validate the accuracy and reliability of GPSPAC orbit solutions, definitive Landsat-4 ephemerides, derived from ground based tracking data, were generated and compared with GPSPAC estimates. In addition, Landsat-4 orbital solutions were reconstructed from raw GPS measurement data with a GPSPAC navigation simulator program using different Kalman filter constants. Ephemeris comparisons and simulator results are presented, as well as recommendations for the navigation filter.

Tuned Mullins-Sekerka instability: Exact results  

NASA Astrophysics Data System (ADS)

Mullins-Sekerka's instability at 3D self-similar growth of a spherical seed crystal in an undercooled fluid is discussed. The exact solution of the linearized stability problem is obtained. It is quite different from the conventional results of the quasisteady approximation. The instability occurs much weaker, so that instead of exponential growth in time, unstable modes exhibit just power-law-growth. The relative growth rates of different modes vary in time and depend on their initial amplitudes. It allows control over the growth of each mode individually and tailoring the instability, to obtain a desired shape of the growing crystal at a given time.

STAR: Recent Results and Future Physics Program  

E-print Network

Two major advantages of the STAR detector - uniform azimuthal acceptance complementing extended pseudo-rapidity coverage, and the ability to identify a wide variety of the hadron species in almost all kinematic ranges - have allowed us to address successfully a set of key physics topics at RHIC. We report here selected recent results from the STAR experiment, including insights on system size effects on medium properties, hadronization mechanisms, and partonic energy loss from triggered and non-triggered probes. In conclusion, we present an outlook on the STAR new physics program in upcoming years.

First Results from the SUNRISE Mission  

NASA Astrophysics Data System (ADS)

The SUNRISE balloon-borne solar observatory consists of a 1m aperture Gregory telescope, a UV filter imager, an imaging vector polarimeter, an image stabilization system, and further infrastructure. The first science flight of SUNRISE yielded high-quality data that reveal the structure, dynamics, and evolution of solar convection, oscillations, and magnetic fields at a resolution of around 100 km in the quiet Sun. Here we describe very briefly the mission and the first results obtained from the SUNRISE data, which include a number of discoveries.

Module Hipot and ground continuity test results  

NASA Technical Reports Server (NTRS)

Hipot (high voltage potential) and module frame continuity tests of solar energy conversion modules intended for deployment into large arrays are discussed. The purpose of the tests is to reveal potentially hazardous voltage conditions in installed modules, and leakage currents that may result in loss of power or cause ground fault system problems, i.e., current leakage potential and leakage voltage distribution. The tests show a combined failure rate of 36% (69% when environmental testing is included). These failure rates are believed easily corrected by greater care in fabrication.

New results on evolving strategies in chess  

NASA Astrophysics Data System (ADS)

Evolutionary algorithms have been used for learning strategies in diverse games, including Othello, backgammon, checkers, and chess. The paper provides a brief background on efforts in evolutionary learning in chess, and presents recent results on using coevolution to learn strategies by improving existing nominal strategies. Over 10 independent trials, each executed for 50 generations, a simple evolutionary algorithm was able to improve a nominal strategy that was based on material value and positional value adjustments associated with individual pieces. The improvement was estimated at over 284 rating points, taking a Class A player and evolving it into an expert.

Recent Results from PHOBOS at RHIC  

NASA Astrophysics Data System (ADS)

The PHOBOS detector is one of four heavy-ion experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. In this paper we will review some of the results of PHOBOS from the data collected in p+p, d+Au and Au+Au collisions at nucleon-nucleon center-of-mass energies up to 200 GeV. In the most central Au+Au collisions at the highest energy, evidence is found for the formation of a very high energy density and highly interactive system, which can not be described in terms of hadrons, and which has a relatively low baryon density.

Experimental results in diffractive processes are summarized and a few notable characteristics described in terms of Quantum Chromodynamics. Exclusive dijet production is used to establish a benchmark for future experiments in the quest for diffractive Higgs production at the Large Hadron Collider. Using new data from the Tevatron and dedicated diffractive triggers, no excess over a smooth falling distribution for exclusive dijet events could be found. Stringent upper limits on the exclusive dijet production cross section are presented. The quark/gluon composition of dijet final states is used to provide additional hints on exclusive dijet production.

Experimental results for absolute cylindrical wavefront testing  

NASA Astrophysics Data System (ADS)

Applications for Cylindrical and near-cylindrical surfaces are ever-increasing. However, fabrication of high quality cylindrical surfaces is limited by the difficulty of accurate and affordable metrology. Absolute testing of such surfaces represents a challenge to the optical testing community as cylindrical reference wavefronts are difficult to produce. In this paper, preliminary results for a new method of absolute testing of cylindrical wavefronts are presented. The method is based on the merging of the random ball test method with the fiber optic reference test. The random ball test assumes a large number of interferograms of a good quality sphere with errors that are statistically distributed such that the average of the errors goes to zero. The fiber optic reference test utilizes a specially processed optical fiber to provide a clean high quality reference wave from an incident line focus from the cylindrical wave under test. By taking measurements at different rotation and translations of the fiber, an analogous procedure can be employed to determine the quality of the converging cylindrical wavefront with high accuracy. This paper presents and discusses the results of recent tests of this method using a null optic formed by a COTS cylindrical lens and a free-form polished corrector element.

Baseline Ozone Results from 1923 to 1955.  

NASA Astrophysics Data System (ADS)

Baseline total atmospheric ozone values have been derived, using the Chappuis band, from historical data for 11 Smithsonian sites, including both Northern and Southern Hemispheres. The main baselines consist of 1194 and 970 days respectively for Mt. Montezuma, Chile and Table Mountain, California, covering a period of time from about 1923 to 1955. These are the two baselines reported on here. An earlier reported decrease in the ozone beginning in 1940 (Angione et al.) is erroneous and resulted from the use of the wavelengths published in the Smithsonian Annals, one of which was incorrect.A modern filter wheel radiometer was used to further develop and evaluate the Chappuis-band method. Two intercomparisons at Mauna Loa Observatory show the Chappuis-band measurements to be systematically lower than simultaneous Dobson values by about 14 percent. Because this difference could result from errors in the ozone absorption coefficients, it is important to firmly establish the correct values of these coefficients in the Chappuis band.

Results from the GPCP algorithm intercomparison programme  

SciTech Connect

Three algorithm intercomparison experiments have recently been conducted as part of the Global Precipitation Climatology Project with the goal of (a) assessing the skill of current satellite rainfall algorithms, (b) understanding the differences between them, and (c) moving toward improved algorithms. The results of these experiments are summarized and intercompared in this paper. It was found that the skill of satellite rainfall algorithms depends on the regime being analyzed, with algorithms producing very good results in the tropical western Pacific and over Japan and its surrounding waters during summer, but relatively poor rainfall estimates over western Europe during late winter. Monthly rainfall was estimated most accurately by algorithms using geostationary infrared data, but algorithms using polar data [Advanced Very High Resolution Radiometer and Special Sensor Microwave/Imager (SSM/I)] were also able to produce good monthly rainfall estimates when data from two satellites were available. In most cases, SSM/I algorithms showed significantly greater skill than IR-based algorithms in estimating instantaneous rain rates. 28 refs., 4 figs., 3 tabs.

Recent heavy ion results from ATLAS experiment  

E-print Network

During the first three years of operation the ATLAS experiment has collected an integrated luminosity of $0.15~\\mathrm{nb}^{-1}$ for $\\sqrt{s_{NN}}=2.76~$TeV lead-lead collisions, $30~\\mathrm{nb}^{-1}$ for 5.02 TeV proton-lead collisions, and $5~\\mathrm{pb}^{-1}$ for $\\sqrt{s}=2.76~$TeV proton-proton collisions. The proton-lead and the high-statistics 2.76 TeV proton-proton data recorded during the highly successful 2013 LHC heavy ion run provide valuable control measurements for interpreting results from lead-lead collisions. Measurements of bulk particle production are presented with a focus on studies of elliptic and higher-order collective flow. Included in these results are measurements of event-by-event collective flow. In addition to providing baseline measurements for the lead-lead program, the proton-lead data also provide a unique opportunity to study the physics of soft and hard scattering in a high parton density environment.
