Sodium pentosan polysulfate resulted in cartilage improvement in knee osteoarthritis - An open clinical trial-  

PubMed Central

Background Pentosan polysulfate sodium (pentosan) is a semi-synthetic drug manufactured from beech-wood hemicellulose by sulfate esterification of the xylopyranose hydroxyl groups. From in vitro and animal model studies, pentosan has been proposed as a disease modifying osteoarthritis drug (DMOAD). The objective of this study was to assess the efficacy, safety, and patient satisfaction in patients with mild radiographic knee osteoarthritis (OA) findings and OA-associated symptoms and signs. Methods Twenty patients were assessed clinically at Nagasaki University Hospital. The radiographic indications of OA were grade 1 to 3 using the Kellgren-Lawrence Grading System (K/L grade). Pentosan used in this study was manufactured and supplied in sterile injectable vials (100 mg/ml) by bene GmbH, Munich, Germany. The study was a single-center, open-label trial. Treatment consisted of 6 weekly subcutaneous injections (sc) of pentosan (2 mg/kg). Patients were clinically assessed at entry and 1 to 8, 11, 15, 24 & 52 weeks post treatment. The results were analyzed using one way ANOVA and Dunnett's method. Results Hydrarthroses were reduced quickly in all cases. The clinical assessments, i.e., knee flexion, pain while walking, pain after climbing up and down stairs, etc, were improved significantly and these clinical improvements continued for almost one year. The dose used in this study affected the blood coagulation test, but was within safe levels. Slightly abnormal findings were noted in serum triglycerides. Conclusions Pentosan treatment in twenty patients with mild knee OA seemed to provide improvements in clinical assessments and C2C level of cartilage metabolism.

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 preserves renal autoregulation in ANG II-infused hypertensive rats via normalization of P2X1 receptor activation  

PubMed Central

Inflammatory factors are elevated in animal and human subjects with hypertension and renal injury. We hypothesized that inflammation contributes to hypertension-induced renal injury by impairing autoregulation and microvascular reactivity to P2X1 receptor activation. Studies were conducted in vitro using the blood-perfused juxtamedullary nephron preparation. Rats receiving ANG II (60 ng/min) infusion were treated with the anti-inflammatory agent pentosan polysulfate (PPS) for 14 days. The magnitude and progression of hypertension were similar in ANG II and ANG II+PPS-treated rats (169 ± 5 vs. 172 ± 2 mmHg). Afferent arterioles from control rats exhibited normal autoregulatory behavior with diameter decreasing from 18.4 ± 1.6 to 11.4 ± 1.7 ?m when perfusion pressure was increased from 70 to 160 mmHg. In contrast, pressure-mediated vasoconstriction was markedly attenuated in ANG II-treated rats, and diameter remained essentially unchanged over the range of perfusion pressures. However, ANG II-treated rats receiving PPS exhibited normal autoregulatory behavior compared with ANG II alone rats. Arteriolar reactivity to ATP and ?,?-methylene ATP was significantly reduced in ANG II hypertensive rats compared with controls. Interestingly, PPS treatment preserved normal reactivity to P2 and P2X1 receptor agonists despite the persistent hypertension. The maximal vasoconstriction was 79 ± 3 and 81 ± 2% of the control diameter for ATP and ?,?-methylene ATP, respectively, similar to responses in control rats. PPS treatment significantly reduced ?-smooth muscle actin staining in afferent arterioles and plasma transforming growth factor-?1 concentration in ANG II-treated rats. In conclusion, PPS normalizes autoregulation without altering ANG II-induced hypertension, suggesting that inflammatory processes reduce P2X1 receptor reactivity and thereby impair autoregulatory behavior in ANG II hypertensive rats.

[A study of inhibitory effect of chondroitin polysulfate on stone formation of calcium oxalate].  


Chondroitin polysulfate (CPS) have inhibitory activity on stone formation of calcium oxalate. This study compared the inhibitory effect of three CPS (CPS S-I, CPS S-II, CPS S-III) with sodium pentosan polysulfate (SPP) and chondroitin sulfate (CS). Crystal growth inhibition was measured in a seeded crystal growth system with 14C-oxalate, and CPS S-I and CPS S-II were the most active substances inhibiting crystal growth. Since CPS S-II and CPS S-III had remarkable hemorrhagic adverse effect, these two substances were excluded from the following study. The study of administration of the rest of the substances (CPS S-I, SPP, CS) to rats revealed that CPS S-I highly inhibited formation of stone in kidney. About 65 percent of CPS S-I administered subcutaneously was excreted in 24 hours urine. Therefore it may be of value to study clinical usefulness of CPS S-I for treatment of patient with urolithiasis. PMID:1434267

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


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

Prediction of hot-water-soluble extractive, pentosan and cellulose content of various wood species using FT-NIR spectroscopy.  


The potential of near infrared spectroscopy in conjunction with partial least squares regression to predict chemical composition of various wood species including softwoods and hardwoods was examined. Hot-water-soluble extractive, pentosan and cellulose content of various wood species were predicted with high coefficient of determination between the predicted and measured values, the ratio of performance to deviation, range error ratio, and low root mean square error of cross validation for cross-validation and root mean square error of prediction for test set validation. Hot-water-soluble extractive and cellulose content models were only suitable for quality control analysis, but pentosan content model had an excellent fit with the data and could be used in any application. All the results indicate that Fourier transform near infrared spectroscopy could be applied to predict the chemical composition of various wood species. PMID:23711938

The antiheparin effect of a heparinoid, pentosan polysulphate. Investigation of a mechanism.  

PubMed Central

A pentosan polysulphate [a fully sulphated (1-4)-beta-D-xylopyranose with a single laterally positioned 4-O-methyl-alpha-D-glucuronic acid] has been shown to inhibit the anticoagulant activity of high-affinity heparin as observed in plasma and when using purified enzyme and inhibitor. The activity was shown to be concentration-dependent with an apparent Ki of approx. 2 microM. The antiheparin property was not shown by a number of other anionic carbohydrates when tested. The rate of thrombin inhibition at 0.33 microM-heparin was reduced from 7.1 X 10(8) M-1 X min-1 in the absence of pentosan polysulphate to 2.3 X 10(8) M-1 X min-1 at 2 microM-pentosan polysulphate and to 0.3 X 10(8)M-1 X min-1 at 20 microM. Using the random bireactant model of heparin action [Griffiths (1982) J. Biol. Chem. 257, 13899-13902] it was observed that the pentosan polysulphate had no effect on the Km for antithrombin III (150 nM) but increased the Km for thrombin from 25 nM to 450 nM. A reduction in the inhibition rate by 17.3-fold predicted by substitution of these values into the general two-substrate reaction-rate equation was confirmed experimentally.

An injectable hydrogel incorporating mesenchymal precursor cells and pentosan polysulphate for intervertebral disc regeneration.  


Intervertebral disc (IVD) degeneration is one of the leading causes of lower back pain and a major health problem worldwide. Current surgical treatments include excision or immobilisation, with neither approach resulting in the repair of the degenerative disc. As such, a tissue engineering-based approach in which stem cells, coupled with an advanced delivery system, could overcome this deficiency and lead to a therapy that encourages functional fibrocartilage generation in the IVD. In this study, we have developed an injectable hydrogel system based on enzymatically-crosslinked polyethylene glycol and hyaluronic acid. We examined the effects of adding pentosan polysulphate (PPS), a synthetic glycosaminoglycan-like factor that has previously been shown (in vitro and in vivo) to this gel system in order to induce chondrogenesis in mesnchymal precursor cells (MPCs) when added as a soluble factor, even in the absence of additional growth factors such as TGF-?. We show that both the gelation rate and mechanical strength of the resulting hydrogels can be tuned in order to optimise the conditions required to produce gels with the desired combination of properties for an IVD scaffold. Human immunoselected STRO-1+ MPCs were then incorporated into the hydrogels. They were shown to retain good viability after both the initial formation of the gel and for longer-term culture periods in vitro. Furthermore, MPC/hydrogel composites formed cartilage-like tissue which was significantly enhanced by the incorporation of PPS into the hydrogels, particularly with respect to the deposition of type-II-collagen. Finally, using a wild-type rat subcutaneous implantation model, we examined the extent of any immune reaction and confirmed that this matrix is well tolerated by the host. Together these data provide evidence that such a system has significant potential as both a delivery vehicle for MPCs and as a matrix for fibrocartilage tissue engineering applications.

Uptake of glycosaminoglycan polysulfate by articular and meniscus cartilage: a biochemical and autoradiographic investigation.  


Incorporation of labeled glycosaminoglycan polysulfate (35S-GPS) into the knee joint was studied biochemically and autoradiographically. After an injection into a knee joint of a rabbit, 35S-GPS was taken up into articular and meniscus cartilage. A 35S-GPS macromolecule and a complex of 4 M GuHCl extracted soluble substance (mainly considered proteoglycan) exists in the articular and meniscus cartilages. A free sulfate, that is, desulfated 35S-GPS, is not incorporated during proteoglycan synthesis. The 35S-GPS remains longer in meniscus cartilage than in articular cartilage. Immediately after intra-articular administration of 35S-GPS, a high grain count was observed in autoradiographs of the perichondrium and the superficial layer of articular cartilage of rats. One day after injection of 35S-GPS, numerous grains were observed in the deep layer. Autoradiography also demonstrated that 35S-GPS turnover is greater in articular cartilage than in meniscus. Uptake of 35S-GPS in an unmodified form in extracellular matrix of articular cartilage should be further investigated in experimental animals with degenerative osteoarthritis. PMID:7449226

Effects of AGM-1470 and pentosan polysulphate on tumorigenicity and metastasis of FGF-transfected MCF-7 cells.  

PubMed Central

Previously, we described FGF-1- or FGF-4-transfected MCF-7 breast carcinoma cells which are tumorigenic and metastatic in untreated or tamoxifen-treated ovariectomised nude mice. In this study, we have assessed the effects of AGM-1470, an antiangiogenic agent, and pentosan polysulphate (PPS), an agent that abrogates the effects of FGFs, on tumour growth and metastasis produced by these FGF-transfected MCF-7 cells. Untreated or tamoxifen-treated ovariectomised mice were injected with FGF-transfected cells, treated with AGM-1470 or PPS, and tumour growth and metastasis analysed. The sensitivity of FGF-transfected and parental MCF-7 cells to AGM-1470 or PPS was also determined in vitro. Both AGM-1470 and PPS inhibited tumour growth in otherwise untreated or tamoxifen-treated mice injected with either FGF- or FGF-4-transfected MCF-7 cells. This effect was more reliably seen in tamoxifen-treated animals. AGM-1470 was about 10(5) times less potent in inhibiting the anchorage-dependent growth of parental MCF-7 or FGF-transfected MCF-7 cells than in inhibiting the growth of human umbilical vein endothelial cells. PPS did not affect the in vitro growth of the transfectants or parental cells. Thus, the growth-inhibitory effect on tumours was in excess of the effect of either drug on the same cells in tissue culture, implying that stromal elements are important determinants of the effects of these drugs. There was a positive correlation between tumour size and the extent of proximal lymph node metastasis. However, neither drug had a significant effect on the extent of metastasis to proximal or distal lymph nodes or lungs. AGM-1470 or PPS may be helpful in cases of breast carcinoma in which angiogenesis is due to expression of FGFs by the tumour cells and may be more effective when combined with tamoxifen.

Meloxicam and surgical denervation of the coxofemoral joint for the treatment of degenerative osteoarthritis in a Bengal tiger (Panthera tigris tigris).  


An adult male white Bengal tiger (Panthera tigris tigris) with pronounced atrophy of the pelvic musculature was diagnosed with degenerative osteoarthritis of the coxofemoral joints. Initial management with the nonsteroidal anti-inflammatory drug meloxicam and a semisynthetic sodium pentosan polysulfate resulted in clinical improvement and radiographic stabilization of the arthritic condition over several months. However, because pain was still evident, bilateral denervation of the coxofemoral joints was performed, successfully ameliorating the signs of osteoarthritic pain in the tiger. Meloxicam has shown good clinical efficacy for the treatment of osteoarthritis and other painful conditions in large felids. Coxofemoral joint denervation offers many advantages for the treatment of osteoarthritis in exotic carnivore species, and should be considered a viable treatment modality. PMID:17319147

Surface interaction between glycosaminoglycans and calcium oxalate.  


Molecules and macromolecules are known to alter the process of crystallization, either through inhibition or promotion of nucleation, growth, and/or aggregation. One particular group of macromolecules, glycosaminoglycans (GAGs), has been of interest in our laboratory. The GAGs chondroitin A, chondroitin C, heparan sulfate, dermatan sulfate, hyaluronic acid, and keratan sulfate have all been shown to be inhibitors of calcium oxalate crystallization. Heparin, the only GAG which is not naturally present in urine, is the most potent inhibitor of all GAGs. Using the method of Langmuir isotherm adsorption, we studied the adsorption of certain GAGs onto calcium oxalate crystals. Under standardized conditions, heparin, chondroitin C, hyaluronic acid, and pentosan polysulfate (a synthetic polyanionic molecule similar to, but a weaker inhibitor than, heparin) were adsorbed onto calcium oxalate. The total amount of GAG required to maximally cover the crystal surface, as well as the equilibrium concentration at which surface was half-covered with GAG (inversely related to the desorption energy) were measured. Chondroitin C was adsorbed in the greatest amount, followed by heparin, pentosan polysulfate, and finally hyaluronic acid. Using the method of fiducial limits, the only insignificant difference was between heparin and chondroitin C, and between hyaluronic acid and pentosan polysulfate. Pentosan polysulfate required significantly higher equilibrium concentration than heparin and hyaluronic acid to cover half of the surface of the calcium oxalate crystals. The principle of Langmuir isotherm adsorption can be useful in predicting the effects of macromolecules on crystallization. Weaker inhibitors bind with less affinity than do stronger inhibitors. Further work is underway to characterize other inhibitors and promoters. PMID:2709520

Therapies for human prion diseases  

PubMed Central

The pathological foundation of human prion diseases is a result of the conversion of the physiological form of prion protein (PrPc) to the pathological protease resistance form PrPres. Most patients with prion disease have unknown reasons for this conversion and the subsequent development of a devastating neurodegenerative disorder. The conversion of PrPc to PrPres, with resultant propagation and accumulation results in neuronal death and amyloidogenesis. However, with increasing understanding of neurodegenerative processes it appears that protein-misfolding and subsequent propagation of these rouge proteins, is a generic phenomenon shared with diseases caused by tau, ?-synucleins and ?-amyloid proteins. Consequently, effective anti-prion agents may have wider implications. A number of therapeutic approaches include polyanionic, polycyclic drugs such as pentosan polysulfate (PPS), which prevent the conversion of PrPc to PrPres and might also sequester and down-regulate PrPres. Polyanionic compounds might also help to clear PrPres. Treatments aimed at the laminin receptor, which is an important accessory molecule in the conversion of PrPc to PrPres – neuroprotection, immunotherapy, siRNA and antisense approaches have provided some experimental promise.

Study of factors affecting calcium oxalate crystalline aggregation.  


A study was made of the effects of citrate, pentosan polysulphate (a glycosaminoglycan) and mucin (a mucoprotein) upon crystalline growth and aggregation of calcium oxalate in synthetic urine. It was found that citrate inhibited aggregation. Pentosan polysulphate had no perceptible effect on aggregation but favoured the formation of calcium oxalate dihydrate crystals. Mucin enhanced the formation of large characteristic aggregates and also led to the formation of calcium oxalate dihydrate crystals. Particles of mucin in a solution served as a substrate on which several crystals of calcium oxalate dihydrate were formed by heterogeneous nucleation; the subsequent growth of these crystals resulted in the formation of large agglomerates.

Interstitial cystitis. Etiology, diagnosis, and treatment.  

PubMed Central

OBJECTIVE: To review current knowledge about the epidemiology, etiology, diagnosis, and treatment of interstitial cystitis, with special emphasis on management of this condition by family physicians. QUALITY OF EVIDENCE: Articles were identified through MEDLINE and review of abstracts presented at Urology and Interstitial Cystitis meetings during the last decade. Recent reviews were further searched for additional studies and trials. Data were summarized from large epidemiologic studies. Etiologic theories were extracted from current concepts and reviews of scientific studies. Diagnostic criteria described in this review are based on clinical interpretation of National Institutes of Health (NIH) research guidelines, interpretation of data from the NIH Interstitial Cystitis Cohort Study, and recent evidence on use of the potassium sensitivity test. Treatment suggestions are based on six randomized placebo-controlled clinical treatment trials and best available clinical data. MAIN MESSAGE: Interstitial cystitis affects about 0.01% to 0.5% of women. Its etiology is unknown, but might involve microbiologic, immunologic, mucosal, neurogenic, and other yet undefined agents. The diagnosis of interstitial cystitis is a diagnosis of exclusion. It is impossible to provide a purely evidence-based treatment strategy, but review of available evidence suggests that conservative supportive therapy (including diet modification); oral treatment with pentosan polysulfate, amitriptyline, or hydroxyzine; and intravesical treatments with heparinlike medications, dimethyl sulfoxide, or BCG vaccine could benefit some patients. CONCLUSION: Family physicians should have an understanding of interstitial cystitis and be able to make a diagnosis and formulate an evidence-based treatment strategy for their patients.

Resultants and loop closure  

NASA Astrophysics Data System (ADS)

The problem of tripeptide loop closure is formulated in terms of the angles {?i} 3i=1 describing the orientation of each peptide unit about the virtual axis joining the C? atoms. Imposing the constraint that at the junction of two such units the bond angle between the bonds C??N and C??C is fixed at some prescribed value ? results in a system of three bivariate polynomials in ui ? tan ?i/2 of degree 2 in each variable. The system is analyzed for the existence of common solutions by making use of resultants, determinants of matrices composed of the coefficients of two (or more) polynomials, whose vanishing is a necessary and sufficient condition for the polynomials to have a common root. Two resultants are compared: the classical Sylvester resultant and the Dixon resultant. It is shown that when two of the variables are eliminated in favor of the third, a polynomial of degree 16 results. To each one of its real roots, there is a corresponding common zero of the system. To each such zero, there corresponds a consistent conformation of the chain. The Sylvester method can find these zeros among the eigenvalues of a 24 × 24 matrix. For the Dixon approach, after removing extraneous factors, an optimally sized eigenvalue problem of size 16 × 16 results. Finally, the easy extension to the more general problem of triaxial loop closure is presented and an algorithm for implementing the method on arbitrary chains is given.

Oscillation results from MINOS  

NASA Astrophysics Data System (ADS)

MINOS has previously presented antineutrino disappearance results based on its first exposure in dedicated antineutrino beam mode corresponding to 1.7×l020 PoT of accumulated data. Here we present an updated antineutrino disappearance result obtained using 70% more antineutrino data. The best fit antineutrino oscillation parameters, ?bar m223 = 2.62+0.31-0.28 × 10-3 eV2 and sin2(2bar theta23) = 0.95+0.10-0.11(stat) + 0.01(syst) are now in good agreement with those obtained for neutrinos. New results on electron neutrino disappearance extracted using an improved analysis technique and 15% more data are also presented. We obtain 90% confidence limits for normal (inverted) mass hierarchy of sin2(2?13) < 0.12 (sin2(2?13) < 0.20).

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 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.

Cleanroom energy benchmarking results  

SciTech Connect

A utility market transformation project studied energy use and identified energy efficiency opportunities in cleanroom HVAC design and operation for fourteen cleanrooms. This paper presents the results of this work and relevant observations. Cleanroom owners and operators know that cleanrooms are energy intensive but have little information to compare their cleanroom's performance over time, or to others. Direct comparison of energy performance by traditional means, such as watts/ft{sup 2}, is not a good indicator with the wide range of industrial processes and cleanliness levels occurring in cleanrooms. In this project, metrics allow direct comparison of the efficiency of HVAC systems and components. Energy and flow measurements were taken to determine actual HVAC system energy efficiency. The results confirm a wide variation in operating efficiency and they identify other non-energy operating problems. Improvement opportunities were identified at each of the benchmarked facilities. Analysis of the best performing systems and components is summarized, as are areas for additional investigation.

Neutrino mass: Recent results  

SciTech Connect

Some recent developments in the experimental search for neutrino mass are discussed. Simpson and Hime report finding new evidence for a 17-keV neutrino in the {beta} decay of {sup 3}H and {sup 35}S. New data from Los Alamos on the electron neutrino mass as measured in tritium beta decay give an upper limit of 13.5 eV at the 95% confidence level. This result is not consistent with the long-standing ITEP result of 26(5) eV within a model-independent'' range of 17 to 40 eV. It now appears that the electron neutrino is not sufficiently massive to close the universe by itself. 38 refs., 1 figs., 2 tabs.

New analyses of Voyager spectra of Titan have led to improvements in the determination of abundances of minor constituents as a function of latitude and altitude. Ground-based microwave observations have extended the Voyager results for HCN, and have demonstrated that CO is mysteriously deficient in the stratosphere. The origin of the CH4, CO, and N2 in Titan's atmosphere is still unresolved. Both primordial and evolutionary sources are compatible with the available evidence. 21 refs.

Explaining embodied cognition results.  


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.

First Results from ALICE  

NASA Astrophysics Data System (ADS)

After nearly 20 years of preparations, first collisions at the LHC commenced in 2009. Since then proton beams have been collided at sqrt(s) = 0.9, 2.76 and 7 TeV, with the majority of the data being recorded at 7 TeV. In the Fall of 2010 another new era was entered when Pb-Pb collisions at 2.76 TeV were also delivered. ALICE's (A Large Ion Collider Experiment) main focus is on exploring the physics of strongly interacting matter created in these events. However, the pp data is also being investigated producing both intriguing new results, and serving as a baseline from which to compare the Pb-Pb data. I will present recent results from ALICE (A Large Ion Collider Experiment)from both the 2010 Pb-Pb run and the ongoing physics analyzes of the pp data. These first Pb-Pb results are broadly consistent with expectations based on lower energy RHIC and SPS data. They indicate that matter created in these collisions, while initially much larger and hotter, still behaves like a very strongly interacting, almost perfect liquid.

ICAAS piloted simulation results  

NASA Astrophysics Data System (ADS)

This paper reports piloted simulation results from the Integrated Control and Avionics for Air Superiority (ICAAS) piloted simulation evaluations. The program was to develop, integrate, and demonstrate critical technologies which will enable United States Air Force tactical fighter 'blue' aircraft to achieve superiority and survive when outnumbered by as much as four to one by enemy aircraft during air combat engagements. Primary emphasis was placed on beyond visual range (BVR) combat with provisions for effective transition to close-in combat. The ICAAS system was developed and tested in two stages. The first stage, called low risk ICAAS, was defined as employing aircraft and avionics technology with an initial operational date no later than 1995. The second stage, called medium risk ICAAS, was defined as employing aircraft and avionics technology with an initial operational date no later than 1998. Descriptions of the low risk and medium risk simulation configurations are given. Normalized (unclassified) results from both the low risk and medium risk ICAAS simulations are discussed. The results show the ICAAS system provided a significant improvement in air combat performance when compared to a current weapon system. Data are presented for both current generation and advanced fighter aircraft. The ICAAS technologies which are ready for flight testing in order to transition to the fighter fleet are described along with technologies needing additional development.

Pressure locking test results  

SciTech Connect

The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, is funding the Idaho National Engineering Laboratory (INEL) in performing research to provide technical input for their use in evaluating responses to Generic Letter 95-07, {open_quotes}Pressure Locking and Thermal Binding of Safety-Related Power-Operated Gate Valves.{close_quotes} Pressure locking and thermal binding are phenomena that make a closed gate valve difficult to open. This paper discusses only the pressure locking phenomenon in a flexible-wedge gate valve; we will publish the results of our thermal binding research at a later date. Pressure locking can occur when operating sequences or temperature changes cause the pressure of the fluid in the bonnet (and, in most valves, between the discs) to be higher than the pressure on the upstream and downstream sides of the disc assembly. This high fluid pressure presses the discs against both seats, making the disc assembly harder to unseat than anticipated by the typical design calculations, which generally consider friction at only one of the two disc/seat interfaces. The high pressure of the bonnet fluid also changes the pressure distribution around the disc in a way that can further contribute to the unseating load. If the combined loads associated with pressure locking are very high, the actuator might not have the capacity to open the valve. The results of the NRC/INEL research discussed in this paper show that the relationship between bonnet pressure and pressure locking stem loads appears linear. The results also show that for this valve, seat leakage affects the bonnet pressurization rate when the valve is subjected to thermally induced pressure locking conditions.

We present the latest results of searches for the production of Higgs bosons at the Tevatron collider in the D0 and CDF experiments. Cross section times branching ratios have been measured in many different topologies and have been interpreted in both the standard model and other models. No evidence for the production of Higgs bosons has been observed, but limits have been set. The D0 and CDF searches in the standard model have been combined and for the first time we exclude part of the possible mass range, 160 GeV to 170 GeV at the 95% confidence level.

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.

We will present the results of a 0.7% measurement of the electron momentum neutron spin angular correlation coefficient ``A'' using polarized ultracold neutrons (UCN) during the 2010 beam cycle at the Los Alamos Neutron Science Center (LANSCE) by the UCNA collaboration. Improvements made to the solid deuterium ultracold neutron source and the neutron guide system allowed us to achieve the a factor of two increase in the decay rate and overall statistics. Major systematic uncertainties, including detector calibration and linearity, electron backscattering, and neutron polarimetry, were reduced, bringing the full sytematic uncertainty to below 0.6% based on the investigations during the 2008-2009 beam cycles.

First results from CARIBU  

NASA Astrophysics Data System (ADS)

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.

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}.

Results from TOTEM  

NASA Astrophysics Data System (ADS)

The TOTEM experiment at the CERN LHC is focussed on the measurement of the elastic proton-proton scattering, the total pp cross-section, and all kinds of diffractive phenomena. Detectors housed in "Roman Pots" which can be moved close to the outgoing proton beams allow to trigger on elastic and diffractive protons and to determine their parameters like the momentum loss and the transverse momentum transfer. In addition, charged particle detectors in the forward regions detect almost all inelastic events. Together with the CMS detector, a large solid angle is covered enabling precise studies of Min. Bias as well as Single Diffractive and Double Pomeron Interactions. The results will considerably help the interpretation of the Cosmic Ray Showers at highest energies and will give insight into the proton structure and the QCD theory of strong interactions. TOTEM measured the elastic pp- scattering over a large range of t (the squared momentum transfer) from 10-3 - 4 GeV2. Noneof the considered models could yield a satisfactory fit over the complete range. However, the exponential slope at low |t|-values and the position of the diffractiveminimum are well within the extrapolation from lower energies. The total pp cross-section has been determined in different ways from the extrapolation of the elasticscattering to t=0 (optical point) and the inelastic rate: (i) From the elastic scattering using the optical theorem and the CMS, (ii) luminosity independently, usingthe inelastic rate, elastic scattering and the optical theorem, (iii)? independently, by using elastic scattering, inelastic rate and the CMS luminosity. The results for the total crosssection obtained from the different methods are in excellent agreement with each other. First studies of the data on diffractive phenomena havebeen performed by correlating the momentum loss of the forward protons with the topology of the particle flux. The data look very promising and further studies will follow. Since the conference, data have also been taken with specialized optics to reach even lower |t|-values. A determination of the ? value is now in reach.The TOTEM results and the ways how they have been obtained are described in the publications [1-8] listed below.

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 (10-6 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.

Iron Mountain Electromagnetic Results  

SciTech Connect

Iron Mountain Mine is located seventeen miles northwest of Redding, CA. After the completion of mining in early 1960s, the mine workings have been exposed to environmental elements which have resulted in degradation in water quality in the surrounding water sheds. In 1985, the EPA plugged ore stoops in many of the accessible mine drifts in an attempt to restrict water flow through the mine workings. During this process little data was gathered on the orientation of the stoops and construction of the plugs. During the last 25 years, plugs have begun to deteriorate and allow acidic waters from the upper workings to flow out of the mine. A team from Idaho National Laboratory (INL) performed geophysical surveys on a single mine drift and 3 concrete plugs. The project goal was to evaluate several geophysical methods to determine competence of the concrete plugs and orientation of the stopes.

[Late results after meniscectomy].  


Lesion of the meniscus is the most frequently occurring lesion in the region of the knee joint. Opinions are still divided as to the effects of partial, subtotal or total meniscectomy in provoking and/or promoting arthrosis. In this study, 70 patients with isolated injury of the meniscus were followed up on an average 11 years after meniscectomy. The subjective and clinical findings are juxtaposed with the x-ray findings. It was found that no arthrosis or no increase of the already preoperatively existing degree of arthrosis was seen in only 21.4% of the patients. Correlations are set up between instability resulting from meniscectomy on the one hand, and degree of arthrosis on the other. PMID:2874703

Recent Results from Milagro  

SciTech Connect

The diffuse gamma radiation arising from the interaction of cosmic ray particles with matter and radiation in the Galaxy is one of the few probes available to study the origin of the cosmic rays. Milagro is a water Cherenkov detector that continuously views the entire overhead sky. The large field-of-view combined with the long observation time makes Milagro the most sensitive instrument available for the study of large, low surface brightness sources such as the diffuse gamma radiation arising from interactions of cosmic radiation with interstellar matter. In this paper we report our results on diffuse emission from the galactic plane and a detailed study of the Cygnus region where we have discovered a new TeV gamma-ray source.

MELCOR validation results  

SciTech Connect

Recent comparisons of MELCOR predictions to three sets of experiments, the ABCOVE Aerosol Experiments, the HDR-V44 Steam Blowdown Experiments, and the Battelle-Frankfurt Gas Mixing Experiments are presentd. All three comparisons involve conditions that are of concern in an LWR containment during a severe accident. MELCOR results are compared to the experimental data and the predictions of at least one other state-of-the-art code for each test. In the ABCOVE comparisons, the MELCOR aerosol modeling is demonstrated. In comparisons to the HDR-V44 Steam Blowdown Experiments, MELCOR predictions of the response of the containment to the release of steam from the primary system are shown, and in the Battelle-Frankfurt comparisons, MELCOR predictions of the diffusion in a containment of an injected hydrogen-nitrogen gas are studied. These comparisons provide critical testing of the MELCOR control volume hydrodynamics package, the radionuclide package, and the flow path package.

Fermi results on AGN  

NASA Astrophysics Data System (ADS)

The Fermi gamma-ray observatory, launched just over two years ago - during the previous MAXI meeting - is performing flawlessly. The most prominent extragalactic point sources are highly variable and luminous jet-dominated active galaxies. Fermi LAT observations, coupled with well-sampled data in radio, mm, IR, optical, X-ray, and TeV gamma-ray bands allow us to probe the structure of relativistic jets, and put new constraints on the location of the region of energy dissipation into radiation. In this talk, I will summarize the gamma-ray properties of AGN measured by Fermi, and will highlight new results for several sources (such as 3C279, Mkn 421, 3C454.3, and AO 0235+164) inferred from multi-band observations.

Recent Results from Phobos  

SciTech Connect

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.

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.

Results of hip resurfacing  

PubMed Central

Background The renewed popularity of resurfacing hip arthroplasty in the last 10 years has generated a remarkable quantity of scientific contributions based on mid- and short-term follow-up. More than one paper has reported a consistent early revision rate as a consequence of biological or biomechanical failure. Two major complications are commonly described with resurfacing implants: avascular necrosis and femoral-neck fracture. A close relationship between these two events has been suggested, but not firmly demonstrated, whereas cementing technique seems to be better understood as potential cause of failure. Methods We performed an in vitro study in which four different resurfacing implants were evaluated with a simulated femoral head, two types of cement, (low and high viscosity) and two cementing techniques: direct (cement apposition directly on the femoral head) and indirect (cement poured into the femoral component). Results High-viscosity cement showed homogeneous distribution over the entire femoral head. Low-viscosity cement showed a massive polar concentration with insufficient, if not absent, distribution in the equatorial zone. Conclusion Polar cement concentration could be a risk factor for early implant failure due to two effects on the femoral head: biological (excessive local exothermic reaction could cause osteocyte necrosis) and biomechanical (which could lead to uneven load distribution on the femoral head).

LSND neutrino oscillation results  

SciTech Connect

The LSND (Liquid Scintillator Neutrino Detector) experiment at Los Alamos has conducted a search for muon antineutrino {r_arrow} electron antineutrino oscillations using muon neutrinos from antimuon decay at rest. The electron antineutrinos are detected via the reaction electron antineutrino + proton {r_arrow} positron + neutron, correlated with the 2.2-MeV gamma from neutron + proton {r_arrow} deuteron + gamma. The use of tight cuts to identify positron events with correlated gamma rays yields 22 events with positron energy between 36 and 60 MeV and only 4.6 {+-} 0.6 background events. The probability that this excess is due entirely to a statistical fluctuation is 4.1 {times} 10{sup -8}. A chi-squared fit to the entire positron sample results in a total excess of 51.8 {sup +18.7}{sub -16.9} {+-} 8.0 events with positron energy between 20 and 60 MeV. If attributed to muon antineutrino {r_arrow} electron antineutrino oscillations, this corresponds to an oscillation probability (averaged over the experimental energy and spatial acceptance) of (0.31 {+-} 0.12 {+-} 0.05){percent}. 10 refs., 7 figs., 1 tab.

VERA status and results  

NASA Astrophysics Data System (ADS)

VERA is a Very Long Baseline Interferometry (VLBI) array for astrometry, composed of four 20 m radio telescopes. They are located over a range of around 2300 km in Japan. VERA consists of a two-beam system equipped with 2, 6.7, 8, 22, and 43 GHz receivers. The two-beam system is used for phase referencing of the VLBI observations, to compensate for atmospheric-turbulence effects between two nearby objects. It has achieved measurements of annual parallaxes within 5 kpc with 10% accuracy. Observed sources are water, SiO, and methanol masers, which are found in molecular gas around star-forming regions and evolved stars. We have carried out a large program of astrometry to reveal the Galaxy's structure and velocity field. VERA has already measured trigonometric parallaxes of more than 30 sources and observed around a hundred sources using the two-beam astrometry technique. Maser sources are associated with high-mass star-forming regions, which are thought to trace the arm structure of the Galaxy. Using annual parallax and proper-motion measurements, their structure will be shown without kinematic distance assumptions. Some sources exhibit large differences between trigonometric-parallax measurements and kinematic distances. We present the status of the VERA project as well as recent results.

Navigating web search results  

NASA Astrophysics Data System (ADS)

Web searches for a specific topic can result in multiple document references for the topic, where information on the topic is redundantly presented across the document set. This can make it difficult for the user to locate a unique piece of information from the document set, or to comprehend the full scope of the information, without examining one document after another in the hope of discovering that new or interesting fact. Summarization techniques reduce the redundancy but often at the cost of information loss. Aggregation is difficult and may present information out of context. This paper presents a method for navigating the document set such that the facts or concepts and their redundant presentations are identified. The user can gain an overview of the concepts, and can locate where they are presented. The user can then view a desired concept as presented in the context of the document of choice. The approach also allows the user to move from concept to concept apart from the sequence of any one particular document. Navigation is accomplished via a graph structure in which redundant material is grouped into nodes. Sequential material unique to a document can also be clustered into a node for a more compact graph representation. Methods for identification of redundant content and for the construction of the navigation graph are discussed.

Recent Dama Results  

NASA Astrophysics Data System (ADS)

DAMA is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.N. The experiment developes and uses low background scintillator for rare processes investigation. In this paper, after a short presentation of the main DAMA set-ups, the DAMA/NaI apparatus (? 100 kg highly radiopure NaI(Tl)) and its main results in the Dark Matter field will be addressed. This experiment, in particular, has effectively investigated the presence of a Dark Matter particle component in the galactic halo by exploiting the model-independent annual modulation signature over seven annual cycles (total exposure of 107731 kg × day), obtaining a 6.3 ? C.L. model-independent evidence for such a presence. In addition, some corollary model-dependent quests to investigate the nature of a candidate particle will be recalled. The new additional analysis for a pseudoscalar and for a scalar bosonic candidate (whose detection only involves electrons and photons/X-rays) will be addressed as well. Some perspectives of the second generation DAMA/LIBRA set-up (? 250 kg highly radiopure NaI(Tl)), presently in measurement deep underground, will be mentioned.

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


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(+).

Bladder pain syndrome/interstitial cystitis: present and future treatment perspectives.  


Bladder pain syndrome/Interstitial cystitis (BPS/IC) is a debilitating chronic disease of unknown etiology. Treatment is not well defined and is still under intense investigation. The aim of this paper was to review existing literature on treatment of BPS/IC and examine current evidence on present and future perspective. PubMed database was researched and publications in English language on the topic were analyzed, emphasis was given to publications that occurred on the last five years. Mainstays of oral therapies are still empirical due to lack of knowledge on etiology of this disease. The few oral drugs that showed efficacy in placebo controlled trials are amytriptiline, pentosan polysulfate sodium, hydroxyzine and cyclosporine A. As for intravesical treatments reasonable evidence is available only for dimethyl sulfoxide and resection of visible Hunner's lesions. Reconstructive surgery can also be recommended in selected cases. Further studies into the causes and mechanisms of the disease are paramount for the development of effective treatments. Foreseeable therapeutic objectives will comprehend oral blockade of sensory nerve receptors, immune system modulation, peripheral nerve fiber inactivation/desensitization, anti-proliferative factor blockade and pain gene therapy. Identification of BPS/IC phenotypical subgroups should help delineate proper individualized treatment which will be aimed at the disease and its multiple manifestations rather than at focalized complaints. Present treatment of BPS/IC comprises pain control in conjunction with control of supposed underlying bladder disease. Based on identified possible therapeutic targets several treatment possibilities warrant further investigation. Identification of BPS/IC phenotype is a important step for correct management.

We give a brief description of the purpose of the LHCf experiment, detectors and their performance, and what has been done in the first year experiment. A short summary of results at s = 900 GeV is given although the energy is not an ``intrinsic'' LHC energy. Since detailed results at s = 7 TeV will appear soon elsewhere, here we limit ourselves to giving also a brief account of what will come in that paper.

The results of ankle arthrodesis.  


The results are presented of 47 compression arthrodeses of the ankle performed for osteoarthritis in 44 patients. In 26 cases the transverse anterior incision of Charnley had been used and in 21 cases medial and lateral incisions with division of the malleoli. Complications included infection (19%), non-union (14.9%) and malposition requiring a further procedure (8.5%). Three patients (6.4%) eventually had an amputation. Clinical assessment using a standard grading method showed that the functional result was not related to the angle of plantar flexion of the ankle, but was related to the varus/valgus position of the heel, the neutral position being associated with the best results. The anterior approach was more reliable in avoiding varus or valgus of the heel. PMID:2298774

New results from FRECOPA analysis  

NASA Astrophysics Data System (ADS)

Given Long Duration Exposure Facility (LDEF) new situation (5.8 years mission), CNES decided to set up a team to analyze FRECOPA systems (AO 138). We studied the kinematic system first. We observed damage on the DELRIN gears and lubricant ageing. The results are based on comparative appraisals between components after flight and those stored on ground in laboratory conditions. We observed also the aluminum surface treatment in the exposed areas and we measured the thermo-optical properties changes. Now, with all the results stored, we try to give a ruling on the use of FRECOPA materials in space environment.

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.

Physical results from unphysical simulations  

NASA Astrophysics Data System (ADS)

We calculate various properties of pseudoscalar mesons in partially quenched QCD using chiral perturbation theory through next-to-leading order. Our results can be used to extrapolate to QCD from partially quenched simulations, as long as the latter use three light dynamical quarks. In other words, one can use unphysical simulations to extract physical quantities-in this case the quark masses, meson decay constants, and the Gasser-Leutwyler parameters L4-L8. Our proposal for determining L7 makes explicit use of an unphysical (yet measurable) effect of partially quenched theories, namely the double-pole that appears in certain two-point correlation functions. Most of our calculations are done for sea quarks having up to three different masses, except for our result for L7, which is derived for degenerate sea quarks.

Marshaling results of nested tasks  

US Patent & Trademark Office Database

The present invention extends to methods, systems, and computer program products for marshaling results of nested tasks. Unwrap methods are used to reduce the level of task nesting and insure that appropriate results are marshaled between tasks. A proxy task is used to represent the aggregate asynchronous operation of a wrapping task and a wrapped task. The proxy task has a completion state that is at least indicative of the completion state of the aggregate asynchronous operation. The completion state of the aggregate asynchronous operation is determined and set from one or more of the completion state of the wrapping task and the wrapped task. The completion state of the proxy task can be conveyed to calling logic to indicate the completion state of the aggregate asynchronous operation to the calling logic.



Top physics results from CDF

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.

The first results from MAXIMA  

NASA Astrophysics Data System (ADS)

This talk reviews the first results from MAXIMA and the scientific implications of the combined MAXIMA and BOOMERANG data sets. The key piece of science is that both experiments independently observe the first acoustic peak in CMB angular power spectrum at a value ~200 and with a width which are compatible with a flat universe and inflation. Both experiments also observe a positive signal which is lower than that previously expected for the second acoustic peak region. A natural economical explanation is that the density of baryons is slightly but noticeably higher than that determined through Big Bang Nucleosynthesis theory. .

Free-electron laser results  

SciTech Connect

The Los Alamos free-electron laser (FEL) amplifier experiment was designed to demonstrate high efficiency for transfer of energy from an electron beam to a light beam in the magnetic field of a tapered wiggler. Initial results indicate an energy transfer consistent with theory. Distinct groups of decelerated electrons as well as accelerated electrons are clearly present in the energy spectrum of electrons emerging from the wiggler when the laser light is present. The observed energy decrease for the electrons captured in the decelerating bucket is approx. 6% and the average decrease of the entire energy distribution is approx. 2% for the conditions of these initial measurements.

RSG Deployment Case Testing Results  

SciTech Connect

The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

CP violation results from CDF

We present world-leading results on CP-violating asymmetries and branching fractions of several decay modes of B{sup 0}, B{sub s}{sup 0}, and {Lambda}{sub b} hadrons into charmless two-body, and of B{sup {+-}} into charm, final states collected by the CDF detector. We also report a new measurement of CP-violating asymmetries in D*{sup {+-}}-tagged D{sup 0} {yields} h{sup +}h{sup -} (h = K or {pi}) decays, where any enhancement from the Standard Model prediction would be unambiguous evidence for New Physics.

"Super-Kamiokande": First Results.  

NASA Astrophysics Data System (ADS)

Flavour oscillation of neutrinos is not only a logical possibility but interpretation of present data suggests likely ranges of the parameters for the oscillation. These parameters include the mass splittings (? m^2), the mixing angles (sin^2(?)) and lower limits of the masses of the neutrinos. Definitive findings would have strong implications in the theory of particles and in astrophysics. The "Super-Kamiokande" experiment with a 50,000ton water Cerenkov detector, became operational in April 1996. Significant data are already collected on tests of the hypothesis of neutrino oscillation. To have definitive measurements of neutrino oscillation, we must measure the flavour identified flux of neutrinos as a function of proper time, and preferably over a large fraction of a period. To accomplish this in Superkamiokande, we are measuring the neutrino fluxes as a function of distance/energy of flavour identified neutrinos as well as the effect of possible mass enhanced neutrino flavour oscillation. The neutrino sources are the sun and the neutrinos produced in the earth's atmosphere by cosmic rays. We will show preliminary measurements of Superkamiokande and their interpretations. Extrapolations of the present results to the higher statistical accuracy expected in 1998 are expected to produce definitive tests of some flavour oscillation hypothesese. Other results will include higher sensitivity searchs for nucleon decay and super novae searches. young/

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.

Results from the Milagrito experiment  

NASA Astrophysics Data System (ADS)

The Milagro water Cherenkov detector near Los Alamos, New Mexico is the first air shower detector capable of continuously monitoring the sky at energies between 500 GeV and 20 TeV. Preliminary results of the Milagro experiment are presented. A predecessor of the Milagro detector, Milagrito, was operational from February 1997 to May 1998. Milagrito consisted of 228 8'' photomultiplier tubes (PMTs) arranged in a grid with a 2.8 meter spacing and submerged in 1-2 meters of water. During its operation, Milagrito collected in excess of 9 billion events with a median energy of about 3 TeV. The detector's sensitivity extends below 1 TeV for showers from near zenith. The results of an all sky search for the Milagrito data for both transient and DC sources will be presented, including the Crab Nebula and active galaxies Markarian 501 and 421, which are known sources of TeV gamma-rays. Also presented will be a study of the TeV emission from gamma ray bursts (GRBs) in Milagrito's field of view detected by the BATSE experiment on the Compton Gamma-Ray Observatory. .

Results from the Magellan altimeter  

NASA Astrophysics Data System (ADS)

During the nominal Magellan mission, the altimeter has made some 3 million measurements of the Venus surface, arranged into a set of 'footprints' covering the latitude range from 85 degrees north to 80 degrees south. Range correlation, Doppler filtering, multiburst summation, and range migration are used in order to focus the data. Maps were prepared showing the global distribution of topography, meter scale slope, and power reflection coefficient. The results are similar to those reported on previous experiments: the surface radius exhibits a unimodal distribution with more than 70 percent of the surface lying within 1 km of the mean radius, but the higher resolution of the Magellan altimeter has disclosed several surprisingly steep features, e.g., the west face of Maxwell Montes, the southern face of Danu Montes, and chasmata to the east of Thetis Regio, where average kilometer scale slopes of greater than 30 deg are not uncommon. This conclusion is corroborated by close inspection of synthetic aperture radar (SAR).

MITG test procedure and results  

SciTech Connect

Elements and modules for Radioisotope Thermoelectric Generator have been performance tested since the inception of the RTG program. These test articles seldom resembled flight hardware and often lacked adequate diagnostic instrumentation. Because of this, performance problems were not identified in the early stage of program development. The lack of test data in an unexpected area often hampered the development of a problem solution. A procedure for conducting the MITG Test was developed in an effort to obtain data in a systematic, unambiguous manner. This procedure required the development of extensive data acquisition software and test automation. The development of a facility to implement the test procedure, the facility hardware and software requirements, and the results of the MITG testing are the subject of this paper.

First year results from LOTIS  

SciTech Connect

LOTIS (Livermore Optical Transient Imaging System) is a gamma-ray burst optical couterpart search experiment located near Lawrence Livermore National Laboratory in California. The system is linked to the GCN (GRB Coordinates Network) real-time coordinate distribution network and can respond to a burst trigger in 6-15 seconds. LOTIS has a total field-of-view of 17.4 degrees x 17.4 degrees with a completeness sensitivity of mv {approximately} 11 for a 10 second integration time. Since operations began in October 1996, LOTIS has responded to over 30 GCN/BATSE GRB triggers. Seven of these triggers are considered good events subject to the criteria of clear weather conditions, {lt}60 S RESPONSE TIME, AND {gt}50% coverage of the final BATSE 3(sigma) error circle. We discuss results from the first year of LOTIS operations with an emphasis on the observations and analysis of GRB 971006 (BATSE trigger 6414).

Broadband acoustooptic deflectors: new results.  


A new broadband acoustooptic (AO) Bragg deflector using acoustic beam steering to track the Bragg angle is described. It features, instead of the conventional stepped array acoustic grating to produce the steering sound column, a flat transducer grating made from a single piezoelectric platelet bonded to the AO medium, with the spatially periodic phase variations created by interdigitating the electrode configuration. The advantage over the conventional stepped array, for deflectors operating at frequencies above 100 MHz, is the ease of fabrication of the device, an advantage that far outweighs its somewhat reduced acoustic power available for light diffraction. An analysis is presented to show that the achievable half-power bandwidth from beam steering deflectors under optimum design considerations is over four times the bandwidth of fixed beam deflectors having the same transducer dimensions. Experimental results on lead molybdate deflectors confirm the predicted fourfold improvement. PMID:20134855

Results from IceCube  

NASA Astrophysics Data System (ADS)

The construction of IceCube neutrino telescope and IceTop surface array was successfully completed at the South Pole during December, 2010. IceCube is the most sensitive telescope to date for observing high energy neutrino sources. The performance of the IceCube detector and a summary of results will be reported from earlier years as the detector increased in size from 40, 59 and 79 strings. New analysis methods developed for the study of the Southern Hemisphere as well as for the extended regions in the sky will be emphasized. The long term experience with AMANDA and IceCube has proven that the South Pole ice is an ideal site for astroparticle physics. New ideas and possible future projects beyond IceCube will also be presented.

Recent Experimental Results from HELIOS  

NASA Astrophysics Data System (ADS)

The renewed emphasis on nuclear structure far from stability, studied with nucleon-transfer reactions that utilize radioactive beams, has led to many new and exciting results. Accompanying these developments are, however many technical challenges that confront studies of transfer reactions in inverse kinematics. Amongst these are the identification of reaction products and the resolution of states in the residual nuclei. A new device, HELIOS (the HELIcal Orbit Spectrometer) has been constructed to solve many of the problems encountered with such reactions. The device uses a uniform magnetic field produced by a large, superconducting solenoid to transport light reaction products from the target to a linear array of position-sensitive silicon detectors. In operation since August of 2008, HELIOS has been used to study a variety of (d,p) reactions with beams of stable and unstable ions with masses ranging from A=11 to 136.

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.

Information extracted from analyses carried out by the SPA Meteor Section from 2007 is presented and discussed. Events covered include: the radio Quadrantid maximum on January 4; a bright fireball seen from parts of England and imaged from the Netherlands at 19h56m UT on February 6, for which an approximate trajectory was established; radio results from the Lyrids in late April; the Perseid near-peak activity from August and a note on some daylight Perseid observing from Britain using thermal imagers; the radio ?-Aurigid maximum on September 1; the Orionid return, which again provided enhanced activity over several consecutive dates in October for visual and radio observers; the radio Leonids, although the probably main peak found visually on November 19 was not recorded thus due to its timing; the typically protracted Geminid maximum period around December 13-15 as observed visually and by radio; and the Ursid outburst, primarily as detected by radio on December 22.

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.

Azimuthal Anisotropy Results from STAR  

NASA Astrophysics Data System (ADS)

Recent advances in the studies of eventwise azimuthal anisotropy from STAR have been made possible by the high statistics 200 GeV Au + Au datasets taken in 2010 and by the broad range of energies recorded during the first phase of the RHIC beam energy scan. The high statistics full energy Au + Au data have allowed precision studies of flow. These include detailed studies of flow versus non-flow, results of elliptic flow at high pT, the ?2 contributions from jets, and elliptic flow of multi-strange hadrons. Data from the beam energy scan enables STAR to search for evidence of the first order phase transition and the onset of deconfinement through the energy systematics of directed flow, elliptic flow, and azimuthally sensitive HBT.

Gravitational microlensing searches and results  

SciTech Connect

Baryonic matter, in the form of Machos (MAssive Compact Halo Objects), might be a significant constituent of the dark matter that dominates the Milky Way. This article describes how surveys for Machos exploit the gravitational microlens magnification of extragalactic stars. The experimental searches for this effect monitor millions of stars, in some cases every night, looking for magnification events. The early results of these surveys indicate that Machos make up a significant fraction of the dark matter in the Milky Way, and that these objects have stellar masses. Truly substellar objects do not contribute much to the total. Additionally, the relatively high event rate towards the Galactic bulge seems to require that the bulge be elongated, and massive.

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.

SciTech Connect

The current design of the Salt Waste Processing Facility (SWPF) includes an auxiliary facility, the Actinide Finishing Facility, which provides a second contact of monosodium titanate (MST) to remove soluble actinides and strontium from waste if needed. This treatment will occur after cesium removal by Caustic-Side Solvent Extraction (CSSX). Although the process changes and safety basis implications have not yet been analyzed, provisions also exist to recover the MST from this operation and return to the initial actinide removal step in the SWPF for an additional (third) contact with fresh waste. A U.S. Department of Energy (DOE) request identified the need to study the following issues involving this application of MST: Determine the effect of organics from the solvent extraction (CSSX) process on radionuclide sorption by MST; Determine the efficiency of re-using MST for multiple contacts; and Examine fissile loading on MST under conditions using a waste containing significantly elevated concentrations of plutonium, uranium, neptunium, and strontium. This report describes the results of three experimental studies conducted to address these needs: (1) Addition of high concentrations of entrained CSSX solvent had no noticeable effect, over a two week period, on the sorption of the actinides and strontium by MST in a direct comparison experiment. (2) Test results show that MST still retains appreciable capacity after being used once. For instance, reused MST--in the presence of entrained solvent--continued to sorb actinides and strontium. (3) A single batch of MST was used to sequentially contact five volumes of a simulant solution containing elevated concentrations of the radionuclides of interest. After the five contacts, we measured the following solution actinide loadings on the MST: plutonium: 0.884 {+-} 0.00539 wt % or (1.02 {+-} 0.0112) E+04 {micro}g/g MST, uranium: 12.1 {+-} 0.786 wt % or (1.40 {+-} 0.104) E+05 {micro}g/g MST, and neptunium: 0.426 {+-} 0.00406 wt % or (4.92 {+-} 0.0923) E+03 {micro}g/g MST. (4) Over the duration of an experiment with the sequential strikes, the ability of MST to sorb actinides improved with additional strikes. This trend is counter-intuitive, but is confirmed by replicate experiments for plutonium, uranium, and neptunium. Conversely, over the duration of the experiment, the ability of MST to sorb strontium decreased the more it was used. This trend is confirmed by replicate experiment.

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.

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.

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.

Vattenfall, the Swedish State Power Board, is searching for a predicted reservoir of abiogenic methane beneath the floor of a meteorite crater in central Sweden. Some of the early scientific results from the drilling project at the Siljan Ring impact structure will be presented on Thursday, May 21, at the 1987 AGU Spring Meeting in Baltimore, Md.Thomas Gold of Cornell University (Ithaca, N.Y.) has predicted that large amounts of methane from deep within the earth may move closer to the surface beneath sites where large meteorites have hit the earth, such as the Siljan Ring structure (Eos, July 9, 1985, p. 537). The site is known for its gas seeps, according to Paul Westcott of the Gas Research Institute (GRI, in Chicago, Ill.). The institute is putting up 15% of the costs of the drillhole in return for access to samples and data. Seismic surveys at the site revealed horizontal structures in the granite, which may suggest the presence of gas-liquid interfaces, Westcott said.

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).

World strength map: preliminary results  

NASA Astrophysics Data System (ADS)

Rheology and strength of the Earth's lithosphere have been debated since the beginning of the last century, when the concept of a strong lithosphere overlying viscous asthenosphere was introduced. The issue of strength of the lithospheric plates and their spatial and temporal variations is important for many geodynamic applications. For rocks with given mineralogical composition and microstructure, temperature is one of the most important parameters controlling rheology. We present the first world strength map obtained from global thermal and crustal models. Temperature estimates for the deeper horizons of the lithosphere, where the heat transport is mostly conductive, requires a precise knowledge of many crustal parameters (mainly thermal conductivity and heat production), which are extremely uncertain. Therefore, we use a combination of indirect approaches, such as seismic tomography and geothermal analysis. Furthermore, we implement a global crustal model on the base of previous compilations. Lithology of the upper and lower crust was classified based on tectonic maps of the World in agreement with the previous study of Tesauro et al. (2009). The results show a good correspondence between strength values and geological features. We observe some general tendency for old cratons and areas affected by the Tertiary volcanism, characterized by high and low strength values, respectively. At the same time, relevant differences in the strength distribution between similar structures are found.

Clinical Results of Extracorporeal Photopheresis  

PubMed Central

Extracorporeal photopheresis (ECP) is a combination of leukapheresis and photodynamic therapy in which blood is treated with photoactivable drugs which are then activated with ultraviolet light and re-infused to the patient. It has been used successfully for more than 30 years in the treatment of erythrodermic cutaneous T-cell lymphoma (CTCL) and over 20 years for chronic graft-versus-host disease (GVHD). ECP has also shown promising results in the treatment of acute GVHD and other T-cell-mediated diseases, including systemic sclerosis, treatment and prevention of solid organ rejection, and more recently Crohn's disease. The use of ECP may allow a significant reduction or even discontinuation of corticosteroids and/or other immunosuppressants, thus leading to reduced long-term morbidity and mortality and improved overall survival. ECP is a well-tolerated therapy. No significant side effects have been reported during the last 30 years. It has been shown that ECP is not associated with an increased incidence of infections, malignancies, or recurrence of underlying malignant disease, neither during short-term nor during long-term therapy.

Results of NSTX Heating Experiments  

SciTech Connect

The National Spherical Torus Experiment (NSTX) at Princeton is designed to assess the potential of the low-aspect-ratio spherical torus concept for magnetic plasma confinement. 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}.

Results from p p colliders  

SciTech Connect

Recent results {bar p}p colliders are presented. From elastic scattering experiments at the Tevatron, an average value of {sigma}{sub tot} = 72.1{plus minus}2 mb is reported, along with a new measurement of {rho} = 0.13 {plus minus} 0.7. New measurements of jet direct photon and high p{sub t} W and Z production are compared to more precise, higher order predictions from perturbative QCD. Recently available data on the W mass and width give combined values for M{sub W} = 80.14{plus minus}0.27 GeV/c{sup 2}, and {Gamma}(W) =2. 14 {plus minus} 0.08 GeV. From electroweak radiative corrections and M{sub W}, one finds M{sub top} = 130{plus minus}40 GeV/c{sup 2}, with a 95% C.L. upper limit at 210 GeV/c{sup 2}. Current limits on M{sub top} are presented, along with a review of the prospects for top discovery. From jet data there is no evidence of quark substructure down to the distance scale of 1.4 {times} 10{sup {minus}17} cm, nor is there evidence for supersymmetry or heavy gauge bosons at {bar p}p colliders, allowing lower limits on M{sub W}, > 520 GeV/c{sup 2} and M{sub Z} 412 GeV/c{sup 2}. 66 refs., 26 figs.

Surgical results for proliferative vitreoretinopathy.  


We reviewed 88 consecutive eyes that underwent vitrectomy for retinal detachment with proliferative vitreoretinopathy (PVR) and were followed a minimum of six months. A primary goal of the surgery was the meticulous trimming of the vitreous base in hopes of decreasing the incidence of post-operative reproliferation and anterior PVR. Those eyes with anterior PVR had aggressive release of vitreous base contraction (anteroposterior and circumferential) with intraocular scissors. All posterior tractional membranes were removed. All eyes received long-acting gas for postoperative retinal tamponade. Macular reattachment was achieved in 78 (88.6%) eyes. Forty-six (52.3%) obtained at least 5/200 vision. Seventeen (19%) eyes were re-operated at least once. We compared the importance of initial lens status (pseudophakic, aphakic, phakic), need for relaxing retinotomy, presence of anterior PVR, and history of previous vitrectomy on the anatomic and visual results. No single factor was responsible for a statistically significant effect on either vision or anatomic success, except for the need for a relaxing retinotomy, which carried with it a decreased chance of an eye obtaining 5/200 vision (Fisher's exact test, p = 0.03).

CMS results in pp collisions  

NASA Astrophysics Data System (ADS)

We present a selection of the first physics results from the CMS experiment in proton-proton collisions, based on data collected at various beam energies during December 2009 and 2010. The measurements include particle production in the soft-QCD regime as well as high-pT spectra and correlations. Inclusive jet production and b-jet production have been studied down to pT below 20 GeV/c, exploiting a novel technique based on the full reconstruction of the event (“particle flow”). Studies of heavy-flavour (open charm and beauty) production have profited from the excellent vertexing performance of the detector, which enables a precise reconstruction of the associated secondary vertices. This capability has also been used to measure the production of J/? mesons promptly produced, independently from those coming from the decay of b hadrons. The production cross sections of the J/? and ? states, in pp collisions at 7 TeV, have been measured in several rapidity intervals and down to very low pT.

Results from the NEXT prototypes  

NASA Astrophysics Data System (ADS)

NEXT-100 is an electroluminescent high pressure Time Projection Chamber currently under construction. It will search for the neutrino-less double beta decay in 136Xe at the Canfranc Underground Laboratory. NEXT-100 aims to achieve nearly intrinsic energy resolution and to highly suppress background events by taking advantage of the unique properties of xenon in the gaseous phase as the detection medium. In order to prove the principle of operation and to study which are the best operational conditions, two prototypes were constructed: NEXT-DEMO and NEXT-DBDM. In this paper we present the latest results from both prototypes. We report the improvement in terms of light collection (~ 3×) achieved by coating the walls of NEXT-DEMO with tetraphenyl butadiene (TPB), the outstanding energy resolution of 1 % (Full Width Half Maximum) from NEXT-DBDM as well as the tracking capabilities of this prototype (2.1 mm RMS error for point-like depositions) achieved by using a square array of 8 × 8 SiPMs.

Heavy Flavor Results from DØ  

NASA Astrophysics Data System (ADS)

Presented are summaries of four heavy flavour analyses by the DØ Collaboration between August 2011 and June 2012. Using up to 10.4 fb of pp¯ collisions at s=1.96 TeV accumulated by the DØ detector at the Fermilab Tevatron collider, we find evidence for the two-body decay Bs0?J/?f2?(1525) and measure the branching fraction of these decays relative to Bs0?J/?? as R=0.22±0.05(stat.)±0.04(syst). The ?b0 lifetime is measured using the fully reconstructed decay ?b0?J/??0, along with the lifetime of the topologically similar decay channel Bd0?J/?Ks0. The analyses yields results of ?(?b0)=1.303±0.075(stat.)±0.035(syst.) ps, ?(Bd0)=1.508±0.025(stat.)±0.043(syst.) ps, and ?(?b0)/?(Bd0)=0.864±0.052(stat.)±0.033(syst.) ps. A narrow mass state is observed that decays into ?(1S)+? with an invariant mass of 10.551±0.014(stat.)±0.017(syst.) GeV/c2. Finally, the semileptonic charge asymmetry is measured to be asls=[?1.08±0.72(stat.)±0.17(syst.)]% using the decay channel Bs0(B¯s0)?Ds??±X.

SuperORRUBA Test Results  

NASA Astrophysics Data System (ADS)

Transfer reactions in inverse kinematics with radioactive ion beams are needed to provide nuclear structure information far from stability to aid in the development of nuclear models and in the understanding of astrophysical processes. Highly granular, low threshold detector arrays are needed to perform such experiments. The SuperORRUBA (Oak Ridge Rutgers University Barrel Array) was created to measure lower threshold reactions with better energy resolution than the original ORRUBA detectors. The new array consists of 18 silicon detectors, each with a 64 non-resistive strip front side and a 4 non-resistive strip back side. To collect the data from these 1224 channels, the ASICs (Application-Specific Integrated Circuits) are used for timing, triggering, shaping, and digitizing the signals, with each chip handling 32 channels. Utilizing the ASICs system and a triple-alpha source, SuperORRUBA detectors were tested to ensure proper function. In addition, all preamps and ASICs elements were tested. The depletion voltage of each detector was found, and the detectors were tested for any shift in gain over time. Finally, issues with crosstalk causing poor resolution on particular channels were investigated. A detailed description of the system and the test results will be presented.

[Mortality results in SENTIERI Project].  


SENTIERI Project (Mortality study of residents in Italian polluted sites) studies mortality of residents in 44 sites of national interest for environmental remediation (Italian polluted sites, IPS). The epidemiological evidence of the causal association between causes of death and exposures was a priori classified into one of these three categories: Sufficient (S), Limited (L) and Inadequate (I). In these sites various environmental exposures are present. Asbestos (or asbestiform fibres as in Biancavilla) has been the motivation for defining six sites as IPSs (Balangero, Emarese, Casale Monferrato, Broni, Bari-Fibronit, Biancavilla). In five of these, increases in malignant neoplasm or pleura mortality are detected; in four of them, results are consistent in both genders. In six other sites (Pitelli, Massa Carrara, Aree del Litorale Vesuviano, Tito, "Aree industriali della Val Basento", Priolo), where other sources of environmental pollution in addition to asbestos are reported, mortality from malignant neoplasm of pleura is increased in both genders in Pitelli, Massa Carrara, Priolo, "Litorale vesuviano". In the time span 1995-2002, a total of 416 extra cases of malignant neoplasm of pleura are detected in the twelve asbestos-polluted sites. Asbestos and pleural neoplasm represent an unique case. Unlike mesothelioma, most causes of death analyzed in SENTIERI have multifactorial etiology; furthermore, in most IPSs multiple sources of different pollutants are present, sometimes concurrently with air pollution from urban areas: in these cases, drawing conclusions on the association between environmental exposures and specific health outcomes might be complicated. Notwithstanding these difficulties, in a number of cases an etiological role could be attributed to some environmental exposures. The attribution could be possible on the basis of increases observed in both genders and in different age classes, and the exclusion of a major role of occupational exposures was thus allowed. For example, a role of emissions from refineries and petrochemical plants was hypothesized for the observed increases in mortality from lung cancer and respiratory diseases in Gela and Porto Torres; a role of emissions from metal industries was suggested to explain increased mortality from respiratory diseases in Taranto and in Sulcis-Iglesiente-Guspinese. An etiological role of air pollution in the raise in congenital anomalies and perinatal disorders was suggested in Falconara Marittima, Massa-Carrara, Milazzo and Porto Torres. A causal role of heavy metals, PAH's and halogenated compounds was suspected for mortality from renal failure in Massa Carrara, Piombino, Orbetello, "Basso bacino del fiume Chienti" and Sulcis-Iglesiente-Guspinese. In Trento-Nord, Grado and Marano, and "Basso bacino del fiume Chienti" increases in neurological diseases, for which an etiological role of lead, mercury and organohalogenated solvents is possible, were reported. The increase for non-Hodgkin lymphomas in Brescia was associated with the widespread PCB pollution. Mortality for causes of death with a priori Sufficient or Limited evidence of association with the environmental exposure exceeds the expected figures, with a SMR of 115.8% for men (90% IC 114.4-117.2; 2 439 extra deaths) and 114.4% for women (90% CI 112.4-116.5; 1 069 extra deaths). These excesses are also observed when analysis is extended to all the causes of death (i.e. with no restriction to the ones with a priori Sufficient or Limited evidence): for a total of 403 692 deaths (both men and women), an excess of 9 969 deaths is observed, with an average of about 1 200 extra deaths per year. Most of these excesses are observed in IPSs located in Southern and Central Italy. The procedures and results of the evidence evaluation are presented in a 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI. PMID:22166295

KLOE results on ? radiative decays  

NASA Astrophysics Data System (ADS)

We report the results on the radiatve decays ? --> ?'?, ? --> ?0?0? and ? --> ??0? obtained with the KLOE detector at the DA?NE ?-factory, using a sample of ~ 16 pb-1. The value of the branching ratio for the ? --> ?'? decay is related to the ss and gluon content of the ?'. A fit to the two-pseudoscalar invariant mass for the ?0?0? and ??0? final states gives the contribution of the direct terms ? --> f0?, ? --> ?? and ? --> a0?, allowing us to investigate the nature of these light scalar mesons.

Results of 189 wrist replacements  

PubMed Central

Background and purpose There is very little literature on the long-term outcome of wrist replacements. The Norwegian Arthroplasty Register has registered wrist replacements since 1994. We report on the total wrist replacements and their revision rates over a 16-year period. Material and methods 189 patients with 189 primary wrist replacements (90 Biax prostheses (80 of which were cementless), 23 cementless Elos prostheses, and 76 cementless Gibbon prostheses), operated during the period 1994–2009 were identified in the Norwegian Arthroplasty Register. Prosthesis survival was analyzed using Cox regression analyses. The 3 implant designs were compared and time trends were analyzed. Results The 5-year survival was 78% (95% CI: 70–85) and the 10-year survival was 71% (CI: 59–80). Prosthesis survival was 85% (CI: 78–93) at 5 years for the Biax prosthesis, 77% (CI: 30–90) at 4 years for the Gibbon prosthesis, and 57% (CI: 33–81) at 5 years for the Elos prosthesis. There was no statistically significant influence of age, diagnosis, or year of operation on the risk of revision, but females had a higher revision rate than males (RR = 3, CI: 1–7). The number of wrist replacements performed due to osteoarthritis increased with time, but no such change was apparent for inflammatory arthritis. Interpretation The survival of the total wrist arthroplasties studied was similar to that in other studies of wrist arthroplasties, but it was still not as good as that for most total knee and hip arthroplasties. However, a failed wrist arthroplasty still leaves the option of a well-functioning arthrodesis.



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.

Recent results in visual servoing  

NASA Astrophysics Data System (ADS)

Visual servoing techniques consist in using the data provided by a vision sensor in order to control the motions of a dynamic system. Such systems are usually robot arms, mobile robots, aerial robots,... but can also be virtual robots for applications in computer animation, or even a virtual camera for applications in computer vision and augmented reality. A large variety of positioning tasks, or mobile target tracking, can be implemented by controlling from one to all the degrees of freedom of the system. Whatever the sensor configuration, which can vary from one on-board camera on the robot end-effector to several free-standing cameras, a set of visual features has to be selected at best from the image measurements available, allowing to control the degrees of freedom desired. A control law has also to be designed so that these visual features reach a desired value, defining a correct realization of the task. With a vision sensor providing 2D measurements, potential visual features are numerous, since as well 2D data (coordinates of feature points in the image, moments, ...) as 3D data provided by a localization algorithm exploiting the extracted 2D measurements can be considered. It is also possible to combine 2D and 3D visual features to take the advantages of each approach while avoiding their respective drawbacks. From the selected visual features, the behavior of the system will have particular properties as for stability, robustness with respect to noise or to calibration errors, robot 3D trajectory, etc. The talk will present the main basic aspects of visual servoing, as well as technical advances obtained recently in the field inside the Lagadic group at INRIA/INRISA Rennes. Several application results will be also described.

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.

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.

Overview of ASDEX Upgrade results  

NASA Astrophysics Data System (ADS)

The closed ASDEX Upgrade Divertor II, `LYRA', is capable of handling heating powers of up to 20 MW or P/R of 12 MW/m, owing to a reduction of the maximum heat flux to the target plates by more than a factor of 2 compared with the open Divertor I. This reduction is caused by high radiative losses from carbon and hydrogen inside the divertor region and is in agreement with B2-EIRENE modelling predictions. At medium densities in the H mode, the type I ELM behaviour shows no dependence on the heating method (NBI, ICRH). ASDEX Upgrade-JET dimensionless identity experiments showed compatibility of the L-H transition with core physics constraints, while in the H mode confinement, inconsistencies with the invariance principle were established. At high densities close to the Greenwald density, the MHD limited edge pressures, the influence of divertor detachment on separatrix parameters and increasing edge transport lead to limited edge densities and finally to temperatures below the critical edge temperatures for H mode. This results in a drastic increase of the H mode threshold power and an upper H mode density limit with gas puff refuelling. The H mode confinement degradation approaching this density limit is caused by the ballooning mode limited edge pressures and `stiff' temperature profiles relating core and edge temperatures. Repetitive high field side pellet injection allows for H mode operation well above the Greenwald density; moreover, higher confinement than with gas fuelling is found up to the highest densities. Neoclassical tearing modes limit the achievable ? depending on the collisionality at the resonant surface. In agreement with the polarization current model, the onset ? is found to be proportional to the ion gyroradius in the collisionless regime, while higher collisionalities are stabilizing. The fractional energy loss connected with saturated modes at high pressures is about 25%. A reduction of neoclassical mode amplitude and an increase of ? have been demonstrated by using phased ECRH and ECCD in the O point of islands. Advanced tokamak operation with internal transport barriers for both ions and electrons has been achieved with flat shear profiles and q0 > 1 or with reversed shear and qmin > 2. With flat shear a stationary H mode scenario was maintained for 40 confinement times and several internal skin times with ?N = 2 and HITERL-89P = 2.4, where fishbones keep q0 at 1. ?N is limited by either neoclassical tearing modes in the case of flat shear or kink modes with reversed shear.

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.

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.

An overview of KSTAR results  

NASA Astrophysics Data System (ADS)

Since the first H-mode discharges in 2010, the duration of the H-mode state has been extended and a significantly wider operational window of plasma parameters has been attained. Using a second neutral beam (NB) source and improved tuning of equilibrium configuration with real-time plasma control, a stored energy of Wtot ˜ 450 kJ has been achieved with a corresponding energy confinement time of ?E ˜ 163 ms. Recent discharges, produced in the fall of 2012, have reached plasma ?N up to 2.9 and surpassed the n = 1 ideal no-wall stability limit computed for H-mode pressure profiles, which is one of the key threshold parameters defining advanced tokamak operation. Typical H-mode discharges were operated with a plasma current of 600 kA at a toroidal magnetic field BT = 2 T. L-H transitions were obtained with 0.8-3.0 MW of NB injection power in both single- and double-null configurations, with H-mode durations up to ˜15 s at 600 kA of plasma current. The measured power threshold as a function of line-averaged density showed a roll-over with a minimum value of ˜0.8 MW at \\bar{n}_e\\sim 2\\times 10^{19}\\,m^{-3} . Several edge-localized mode (ELM) control techniques during H-mode were examined with successful results including resonant magnetic perturbation, supersonic molecular beam injection (SMBI), vertical jogging and electron cyclotron current drive injection into the pedestal region. We observed various ELM responses, i.e. suppression or mitigation, depending on the relative phase of in-vessel control coil currents. In particular, with the 90° phase of the n = 1 RMP as the most resonant configuration, a complete suppression of type-I ELMs was demonstrated. In addition, fast vertical jogging of the plasma column was also observed to be effective in ELM pace-making. SMBI-mitigated ELMs, a state of mitigated ELMs, were sustained for a few tens of ELM periods. A simple cellular automata (‘sand-pile’) model predicted that shallow deposition near the pedestal foot induced small-sized high-frequency ELMs, leading to the mitigation of large ELMs. In addition to the ELM control experiments, various physics topics were explored focusing on ITER-relevant physics issues such as the alteration of toroidal rotation caused by both electron cyclotron resonance heating (ECRH) and externally applied 3D fields, and the observed rotation drop by ECRH in NB-heated plasmas was investigated in terms of either a reversal of the turbulence-driven residual stress due to the transition of ion temperature gradient to trapped electron mode turbulence or neoclassical toroidal viscosity (NTV) torque by the internal kink mode. The suppression of runaway electrons using massive gas injection of deuterium showed that runaway electrons were avoided only below 3 T in KSTAR. Operation in 2013 is expected to routinely exceed the n = 1 ideal MHD no-wall stability boundary in the long-pulse H-mode (?10 s) by applying real-time shaping control, enabling n = 1 resistive wall mode active control studies. In addition, intensive works for ELM mitigation, ELM dynamics, toroidal rotation changes by both ECRH and NTV variations, have begun in the present campaign, and will be investigated in more detail with profile measurements of different physical quantities by techniques such as electron cyclotron emission imaging, charge exchange spectroscopy, Thomson scattering and beam emission spectroscopy diagnostics.

ResultMaps: visualization for search interfaces.  


Hierarchical representations are common in digital repositories, yet are not always fully leveraged in their online search interfaces. This work describes ResultMaps, which use hierarchical treemap representations with query string-driven digital library search engines. We describe two lab experiments, which find that ResultsMap users yield significantly better results over a control condition on some subjective measures, and we find evidence that ResultMaps have ancillary benefits via increased understanding of some aspects of repository content. The ResultMap system and experiments contribute an understanding of the benefits--direct and indirect--of the ResultMap approach to repository search visualization. PMID:19834172

Results of surgical treatment of patellar fractures.  


Sixty-four patellar fractures treated either by internal fixation or by patellectomy were reviewed retrospectively from 3.5 to 10.1 years (average 6.2 years) after operation. Results were assessed subjectively and objectively. Of the 64 patients, 45% had a good result, 27% fair and 28% poor. On the whole, patellectomy produced better results (60% good, 20% fair, 20% poor), than internal fixation (31% good, 33% fair, 36% poor). Nevertheless, the best results of all were achieved by precise anatomical reduction of the patellar fracture and fixation with K-wires and a tension band. Where this could not be achieved, however, patellectomy gave the best results. PMID:3997951

Selected results in lattice quantum chromodynamics  

NASA Astrophysics Data System (ADS)

The results of the Budapest-Marseille-Wuppertal Collaboration are summarized. Both T = 0 and T > 0 findings are presented. Special emphasis is put on the "physical point" (which is used to describe results with physical quark masses extrapolated all the way to the continuum limit). At T = 0, the light hadron spectrum, FK/F?, the quark masses, and the kaon bag parameter are discussed. At T > 0, results for the nature of the quantum chromodynamics transition, the transition temperature, the equation of state (both at vanishing and nonvanishing chemical potentials), the curvature of the phase diagram, and the effects of magnetic fields are discussed. All these results are full results (representing findings at physical quark masses in the continuum limit).

Reconciling the CAST and PVLAS Results  

SciTech Connect

The PVLAS experiment has recently claimed evidence for an axionlike 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 pseudoscalar particle interacting with two photons and a scalar boson and the existence of a low scale phase transition in the theory.

Return of results: towards a lexicon?  


Currently, the return of results in the domain of biobanking constitutes an ethical and legal quagmire, whether it involves population or specific clinical research studies. In light of the fact that population biobanks are often not seen as distinct from those biobanks created for disease research, as well as the uncertainty as to what "return of results" means concretely, this lexicon attempts to demystify the terminology. The terms - results, return, clinical significance, and utility - are discussed. Through an analysis of international and national normative guidance on this issue, the authors propose a concordance of meaning and a simplified lexicon. PMID:22084843

First Results on Large-Scale Structure  

NASA Astrophysics Data System (ADS)

Early large scale structure work includes results from both the photometric and the spectroscopic parts of the Survey. Two nights of early SDSS photometric data are introduced, in which over a million galaxies were imaged. A star-galaxy separator is discussed; it works well down to 22nd magnitude. The angular correlation function of these galaxies is presented out to scales larger than a degree. This angular correlation function is then inverted to obtain a preliminary power spectrum from SDSS. This is compared with theoretical models and results from previous surveys. Early spectroscopic results are also presented. In particular, the clustering properties in redshift space have been measured. These early results bode well for the future of the survey, strongly suggesting that its scientific potential will be realized.

A sample of recent results in muon scattering measurements from the COMPASS experiment at CERN will be reviewed. These include high energy processes with longitudinally polarised proton and deuteron targets. High energy polarised measurements provide important constraints for studying the nucleon spin structure and thus permit to test the applicability of the theoretical framework of factorisation theorems and perturbative QCD. Specifically, latest results on longitudinal quark polarisation, quark helicity densities and gluon polarisation will be reviewed.

Pulmonary hemorrhage is a relatively common complication of blunt chest trauma. Occasionally, it may result from pulmonary barotrauma after scuba diving or from sports activities not associated with barotrauma such as long breath-hold diving. We report a case of symmetric diffuse upper lobe hemorrhage resulting from a bungee jump in a previously healthy man. Bungee jumping is an increasingly popular sport with relatively few reported injuries. To our knowledge pulmonary hemorrhage in this setting has not yet been described. PMID:18043394

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.

SDO-AIA DEM: Initial Results  

NASA Astrophysics Data System (ADS)

The Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory has state-of-the-art spatial resolution and shows the most detailed images of coronal loops ever observed. The series of coronal filters peak at different temperatures, which span the range of active regions. These features represent a significant improvement over earlier coronal imagers and make AIA ideal for multi-thermal analysis. Here we targeted a 171-A coronal loop in AR 11092 observed by AIA on 2010 August 3. Isothermal analysis using the 171-to-193 ratio gave a temperature of Log T = 6.1, similar to the results of EIT and TRACE. Differential Emission Measure analysis, however, showed that the plasma was multithermal, not isothermal, with a distribution that peaked between Log T = 6.3 and 6.4. The result from the isothermal analysis, which is the average of the true plasma distribution weighted by the instrument response functions, appears to be deceptively low. These results have potentially serious implications: EIT and TRACE results, which use the same isothermal method, show substantially smaller temperature gradients than predicted by standard models for loops in hydrodynamic equilibrium and have been used as strong evidence in support of footpoint heating models. These implications may have to be re-examined in the wake of new results from AIA.

Latest result of PRK with excimer laser  

NASA Astrophysics Data System (ADS)

We have in the last two years, performed PRK operation on over 300 human myopic eyes using ArF excimer laser with a Summit 'Omnimed' machine. For the initial 53 myopic eyes we treated, results were very good for those with correction less than minus 6 diopters. However, as previously reported, we also witnessed some regression for those eyes exceeding correction of more than minus 6 diopters. To counter such ill results of PRK we devised and suggested many new procedures for PRK with very good results. One such invention is the 'Okamoto-type' cooling machine for the cornea which reduces and stabilizes cornea temperature at 0 degrees Celsius while simultaneously bathing the cornea with special cooling fluid. After the operation, EGF, fibronectin and hexapeptide were administered using eyedrops. Soft contact lenses were used to protect the cornea, improve delivery of medication to the operated area, prevent infection and inflammation and also promote uniform and faster ephiterium regrowth. We were able to document very good post-operative results using this method, thereby giving us strong assurance that we have reached a significant milestone in PRK operation. Our report today covers post operative results of the 52 eyes we operated on and tracked for more than one year.

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.

East Mountain Area 1995 air sampling results  

SciTech Connect

Ambient air samples were taken at two locations in the East Mountain Area in conjunction with thermal testing at the Lurance Canyon Burn Site (LCBS). The samples were taken to provide measurements of particulate matter with a diameter less than or equal to 10 micrometers (PM{sub 10}) and volatile organic compounds (VOCs). This report summarizes the results of the sampling performed in 1995. The results from small-scale testing performed to determine the potentially produced air pollutants in the thermal tests are included in this report. Analytical results indicate few samples produced measurable concentrations of pollutants believed to be produced by thermal testing. Recommendations for future air sampling in the East Mountain Area are also noted.

Review of Fenton Hill HDR test results  

SciTech Connect

Results of recent flow testing at Fenton Hill, New Mexico, have been examined in light of their applicability to the development of commercial-scale hot dry rock (HDR) reservoirs at other sites. These test results, obtained during the cumulative 11 months of reservoir flow testing between 1992 and 1995, show that there was no significant production temperature drawdown during this time and that the reservoir flow became more dispersed as flow testing proceeded. Based on these test results together with previous HDR research at Fenton Hill and elsewhere, it is concluded that a three-well geometry, with one centrally located injection well and two production wells-one at each end of the pressure-stimulated reservoir region-would provide a much more productive system for future HDR development than the two-well system tested at Fenton Hill.

HRS pilot plant and modeling results  

SciTech Connect

At Lawrence Livermore National Laboratory, we are studying Hot-Recycled-Solid (HRS) oil shale retorting processes through a series of fundamental laboratory studies, operation of a 4 tonne-per-day HRS pilot plant and development of an Oil Shale Process (OSP) mathematical model. Results from the pilot plant and process model development are discussed in this paper. Over the last year, results from the pilot plant, using lean and rich shales (22 to 38 gallon-per-ton) have proven process viability in a robust design with no moving parts, utilizing gravity feed to fluid and packed-beds and pneumatic solids transport in a lift-pipe. Using the OSP process model,, which is under development, we critically assess pilot plant results while building a tool to aid in scaleup of the HRS process.

Testing alleged mediumship: methods and results.  


Mediums claim to be able to communicate with the deceased. Such claims attract a considerable amount of public interest and, if valid, have important implications for many areas of psychology. For over 100 years, researchers have tested alleged mediums. This work has obtained mixed results and provoked a considerable amount of methodological debate. This paper reviews the key issues in this debate, describes how the authors devised a method of testing that aimed to prevent the many problems that have hindered past research, and how they then used this method to test several professional mediums. The results of this work did not support the existence of genuine mediumistic ability. Competing interpretations of these results are discussed, along with ways in which the methodology presented in the paper could be used to assess conceptually similar, but non-paranormal, claims made in clinical, occupational and forensic contexts.

New results from ADEOS-II/GLI  

NASA Astrophysics Data System (ADS)

The first light images from the ADEOS-II (Midori-II) / GLI were obtained on January 25, 2003 successfully. The GLI is a cross tracking imager with 36 channels covering a wide spectral region from 380 nm to 12 ?m. Six 250m channels and tilting ocean view mechanism are also unique features of the GLI. Obtained radiance images are now being analyzed at NASDA EORC to produce the level 2 geophysical products. This paper overviews some standard and new products and their implications for local and global researches. It is important to compare the satellite-derived results with model simulation results. We compared the MODIS result with cloud microphysical simulation with the NHM+HUCM model and found a similar distribution of cloud effective radii.

On the reliability of reverse engineering results.  


Determination of actual parameters of manufactured optical coatings (reverse engineering of optical coatings) provides feedback to the design-production chain and thus plays an important role in raising the quality of optical coatings production. In this paper, the reliability of reverse engineering results obtained using different types of experimental data is investigated. Considered experimental data include offline normal incidence transmittance data, offline ellipsometric data, and online transmittance monitoring data recorded during depositions of all coating layers. Experimental data are obtained for special test quarter-wave mirrors with intentional errors in some layers. These mirrors were produced by a well-calibrated magnetron-sputtering process. The intentional errors are several times higher than estimated errors of layer thickness monitoring, and the reliability of their detection is used as a measure of reliability of reverse engineering results. It is demonstrated that the most reliable results are provided by online transmittance data. PMID:22859046

Relativity concept inventory: Development, analysis, and results  

NSDL National Science Digital Library

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.

Reactor calculation ''Benchmark'' PCA blind test results  

SciTech Connect

The PCA-PV Benchmark Facility was used to test the accuracy of neutron transport calculations. Several laboratories in the PCA Blind Test, including vendors of power reactors, calculated the neutron flux-spectra and reaction rates of foil detectors for specified locations in the PCA Benchmark. This was done without prior knowledge of the results of dosimetry measurements which were performed in the same configurations.

Spatially organized visualization of image query results  

NASA Astrophysics Data System (ADS)

In this work we present a system which visualizes the results obtained from image search engines in such a way that users can conveniently browse the retrieved images. The way in which search results are presented allows the user to grasp the composition of the set of images "at a glance". To do so, images are grouped and positioned according to their distribution in a prosemantic feature space which encodes information about their content at an abstraction level that can be placed between visual and semantic information. The compactness of the feature space allows a fast analysis of the image distribution so that all the computation can be performed in real time.

The recent results from KIMS experiment  

NASA Astrophysics Data System (ADS)

In this paper, the recent results from KIMS (Korea invisible mass search) experiment are presented. KIMS has searched for WIMPs (Weakly Interactig Massive Particles) scattering off the nucleus by using the CsI(Tl) scintillator. The detector is an array of 12 CsI(Tl) scintilltors, whose total mass is 103.4 kg. The results reported here used the exposure of 24524.3 kg-days. With pulse shape discrimination (PSD) analysis, we estimated the nuclear recoil (NR) event rate and no meaningful excess of NR events rate were found. From this, we derived the improved cross section limit for WIMP-nucleon interaction.

Preliminary results of impeller design modifications  

NASA Astrophysics Data System (ADS)

Power consumption in the oil mixing process is very much affected by the impeller design. Minor modification on the impeller design might result in better mixing and less energy consumption. This paper reports an early stage of applying the observation technique to modify three standard impellers, namely the Pitched blade turbine impeller, the CHEMSHEAR impeller and the Vertical Flat-Blade Turbine Impeller. The advantages and disadvantages of these three impellers were analyzed; accordingly minor modification on the impeller design is adopted. The CFD tool is used to evaluate one of the modified impellers; results indicated that the modified impeller achieves better fluid dispersion.

Results and outcomes of unicompartmental knee arthroplasty.  


Precise outcome evaluation is mandatory to improve analysis of the results of knee replacement procedures. Patients' expectations toward surgery and activity levels have increased with changes in patient populations and improvement of surgical results. It is difficult, however, to accurately assess outcomes because objective evaluation of patient function performed only by a surgeon remains highly inaccurate. New methods of objective evaluation after unicompartmental knee arthroplasty have been developed. These devices provide information about range of motion and patient function during daily activities. This article provides up-to-date information concerning the different tools of function evaluation after unicompartmental knee arthroplasty. PMID:23827833

Stellar spectroscopy with CCDs - some preliminary results  

NASA Astrophysics Data System (ADS)

The appeal of CCDs is speed - getting instant results (like the visual observer) and supreme sensitivity. Although the CCD user may now have a permanent record to tweak at leisure, nothing compares to that initial view. When coupled to a simple prism innocuous points of starlight give up their secrets in real-time. A technique of using an objective prism before a reflecting telescope with a CCD detector to record stellar spectra is described and some results explained. The spectral sensitivity of the camera can be tested as a byproduct.

Highlight Results of the HEGRA Collaboration  

NASA Astrophysics Data System (ADS)

The HEGRA experiment (High Energy Gamma Ray Astronomy) was operating 6 Cherenkov Telescopes on the Canary Island of La Palma until fall 2002 in the TeV energy regime. Five of these telescopes were operated in coincidence mode (stereoscopy), thus pioneering the stereoscopic observation technique, subsequently adopted by most of the next generation of Cherenkov Telescope experiments. Throughout the operation of the HEGRA stereoscopic system unique results have been obtained for different object classes such as Active Galactic Nuclei, Plerions, shell-type Super Nova Remnants and an unidentified source. A review of the most important results on various detections will be given.

[Long-term results of acetabuloplasty].  


The results of a modified acetabuloplasty after Albee-Lance performed simultaneously with a derotation-varusosteotomy (DVO) are investigated after cessation of growth. Measurements of the acetabulum have been normal or slightly pathologic after our classification system in 82-93%, while the values of the femoral head and neck showed a higher pathologic percentage. This is due to avascular necrosis after conservative or operative treatment, insufficient open reductions in a smaller number, but in the most cases caused by increased revalgisation after DVO. We have therefore performed acetabuloplasty since several years without DVO in the most cases, so far with good results. PMID:3213162

Hemicellulose bioconversion to polyanionic heteropolysaccharides.  


Anionic polysaccharides, traditionally obtained from plant or algal sources, have a variety of commercial uses. Such gums from microorganisms have received increased recent interest. We have initiated a program to investigate the bioconversion of pentosans to rheologically useful anionic extracellular polysaccharides (AEPS). A number of earlier-described species, including Cryptococcus laurentii, Klebsiella pneumoniae, Arthrobacter viscosus, and Pseudomonas ATCC 31260, appear to have potential in this regard. These organisms can individually convert either xylose, enzymatic oligomeric hemicellulose digests, dilute mineral acid hemicellulose ("TVA") hydrolysates, or a five-monosaccharide mixture simulating sulfite process liquors to AEPS. The formation parameters, compositions, mol-wt distributions, and the intrinsic viscosities of these purified AEPS are exemplified. Substitution of pentose as the major substrate for glucose can result in changes in mol-wt distribution or in the percentage of noncarbohydrate substituents in some AEPS. Pursuit of these observations may lead to interesting structure-property relationships and toward rheological applications for pentosan-derived AEPS. PMID:1622201

First Results with the Rising Active Stopper  

NASA Astrophysics Data System (ADS)

This paper outlines some of the physics opportunities available with the GSI RISING active stopper and presents preliminary results from an experiment aimed at performing beta-delayed gamma-ray spectroscopic studies in heavy-neutron-rich nuclei produced following the projectile fragmentation of a 1 GeV per nucleon 208Pb primary beam. The energy response of the silicon active stopping detector for both heavy secondary fragments and beta-particles is demonstrated and preliminary results on the decays of neutron-rich Tantalum (Ta) to Tungsten (W) isotopes are presented as examples of the potential of this technique to allow new structural studies in hitherto experimentally unreachable heavy, neutron-rich nuclei. The resulting spectral information inferred from excited states in the tungsten daughter nuclei are compared with results from axially symmetric Hartree-Fock calculations of the nuclear shape and suggest a change in ground state structure for the N = 116 isotone 190W compared to the lighter isotopes of this element.

The Rosseland mean opacities computed using the OPAL codes show significant differences when compared to the Los Alamos results. The differences have been traced to improvements in both the equation of state and atomic physics in the OPAL code. Furthermore, recent work suggests that the OPAL opacities considerably improve the agreement between observations and stellar models. Key words: OPACITIES - SUN: INTEMOR - STARS: VARIABLE

New Results on Nucleon Spin Structure  

SciTech Connect

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{sub 1}{sup n}, in the high-x region are discussed. The new data shows clearly, for the first time, that A{sub 1}{sup n} becomes positive at high x. They provide crucial input for the global fits to world data to extract polarized parton distribution functions. Preliminary results on A{sub 1}{sup p} and A{sub 1}{sup d} in the high-x region have also become available. 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{sub 2}{sup n} structure function to study higher-twist effects are presented. The data show a clear deviation from the lead-twist contribution, indicating a significant higher-twist (twist-3 or higher) effect. The second moment of the spin structure functions and the twist-3 matrix element d{sub 2}{sup n} results were extracted at a high Q{sup 2} of 5 GeV{sup 2} from the measured A{sub 2}{sup n} in the high-x region in combination with existing world data and compared with a Lattice QCD calculation. Results for d{sub 2}{sup n} at low-to-intermediate Q{sup 2} from 0.1 to 0.9 GeV{sup 2} were also extracted from the JLab data. In the same Q{sup 2} range, the Q{sup 2} 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 and compared with Chiral Perturbation Theory calculations and phenomenological models. Finally, preliminary results on the resonance spin structure functions in the Q{sup 2} range from 1 to 4 GeV{sup 2} were presented, which, in combination with DIS data, will enable a detailed study of the quark-hadron duality in spin structure functions.

Initial results from the Madison Dynamo Experiment  

NASA Astrophysics Data System (ADS)

The Madison dynamo experiment is designed to self-generate magnetic fields from flows of conducting metal in a simply connected spherical geometry. This talk will present initial results from the experiment since commencement of operations in August of 2004. Thus far, the experiment has been operated at 60% of its design specifications achieving magnetic Reynolds numbers of 130, based on propellor tip speed. The technical operation of the experiment has been demonstrated (i.e., transfers of liquid sodium, rotating seals, etc). The experimental approach to understanding the electromagnetic properties of the sodium involves comparisons between experimental measurements of the magnetic field in the sodium experiment, measurements of the velocity field in a dimensionally identical water experiment, and predictive MHD codes that model the currents induced in the turbulent flows by externally applied fields. Initial results include: direct observation of an ? effect, the production of a toroidal magnetic field from a poloidal magnetic field; the expulsion of poloidal flux by vortical fluid motion; measurement of gain for the expected dynamo eignenmode; and measurement of the turbulent shredding of a large scale magnetic field by small scale turbulence, as determined from a spatial array of magnetic probes generating mode number spectra. As background, the theoretical basis for the experiment and hydromagnetic modeling results will be reviewed, including results from recent 3D MHD computation of the backreaction and the role of turbulence on self-excitation. An interesting implication of the simulations is that one role of the turbulence is to increase the critical magnetic Reynolds number for self-excitation, a result consistent with an increased resistivity due to the turbulence, as in the beta effect. Future plans will be discussed, including the strategy observing self-excitation.

The Usefulness of Dynamically Categorizing Search Results  

PubMed Central

Objective: The authors' goal was to determine whether dynamic categorization, a new technique for organizing search results, is more useful than the two existing organizational techniques: relevance ranking and clustering. They define a useful tool as one that helps users learn about the kinds of information that pertain to their query, find answers to their questions efficiently and easily, and feel satisfied with their search experience. Design: Fifteen patients with breast cancer and their family members completed query-related tasks using all three tools. The authors measured the time it took the subjects to accomplish their tasks, the number of answers to the query that the subjects found in four minutes, and the number of new answers that they could recall at the end of the study. Subjects also completed a user-satisfaction questionnaire. Results: The results showed that patients with breast cancer and their family members could find significantly (P < 0.05) more answers in a fixed amount of time and were significantly (P < 0.05) more satisfied with their search experience when they used the dynamic categorization tool than when they used either the cluster tool or the ranking tool. Subjects indicated that the dynamic categorization tool provided an organization of search results that was more clear, easy to use, accurate, precise, and helpful than those of the other tools. Conclusion: The experiments indicate that dynamic categorization is an effective and useful approach for organizing search results. Tools that use this technique will help patients and their families gain quick and easy access to important medical information.

Compact tokamak reactors part 2 (numerical results)  

SciTech Connect

The authors describe a numerical optimization scheme for fusion reactors. The particular application described is to find the smallest copper coil spherical tokamak, although the numerical scheme is sufficiently general to allow many other problems to be solved. The solution to the steady state energy balance is found by first selecting the fixed variables. The range of all remaining variables is then selected, except for the temperature. Within the specified ranges, the temperature which satisfies the power balance is then found. Tests are applied to determine that remaining constraints are satisfied, and the acceptable results then stored. Results are presented for a range of auxiliary current drive efficiencies and different scaling relationships; for the range of variables chosen the machine encompassing volume increases or remains approximately unchanged as the aspect ratio is reduced.

High tibial osteotomy: does navigation improve results?  


Between January 2003 and March 2006, the authors performed 67 open-wedge high tibial osteotomies (HTO) for treatment of genu varum and osteoarthritis. Through comparison of two groups, the study sought to answer whether computed tomography (CT)-free navigation is feasible for HTO and will provide a more accurate correction angle without giving rise to additional complications. The results showed a significantly higher accuracy in achieving the proper leg axis correction (P< .016) when HTO was performed with navigation. Navigation in HTO, which allows intraoperative calculation of the leg axis, seems to be a reliable and safe procedure. Knowing that clinical results of HTO in varus deformity of the leg axis are closely connected to correct postoperative valgus alignment and avoiding overcorrection and undercorrection, the study lead to the conclusion that the use of navigation will contribute to better clinical outcomes.

SLS-1 flight experiments preliminary significant results  

NASA Astrophysics Data System (ADS)

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.



$W/Z$ + jets results from CDF

The CDF Collaboration has a comprehensive program of studying the production of vector bosons, W and Z, in association with energetic jets. Excellent understanding of the standard model W/Z+jets and W/Z+c,b-jets processes is of paramount importance for the top quark physics and for the Higgs boson and many new physics searches. We review the latest CDF results on Z-boson production in association with inclusive and b-quark jets, study of the p{sub T} balance in Z+jet events, and a measurement of the W+charm production cross section. The results are based on 4-5 fb{sup -1} of data and compared to various Monte Carlo and next-to-leading order perturbative QCD predictions.

CLSM bleed water reduction test results  

SciTech Connect

Previous testing by BSRI/SRTC/Raytheon indicated that the CLSM specified for the Tank 20 closure generates about 6 gallons (23 liters) of bleed water per cubic yard of material (0.76 m3).1 This amount to about 10 percent of the total mixing water. HLWE requested that the CLSM mix be optimized to reduce bleed water while maintaining flow. Elimination of bleed water from the CLSM mix specified for High-Level Waste Tank Closure will result in waste minimization, time savings and cost savings. Over thirty mixes were formulated and evaluated at the on-site Raytheon Test Laboratory. Improved low bleed water CLSM mixes were identified. Results are documented in this report.

First Results from DAMA/LIBRA  

SciTech Connect

The highly radiopure {approx_equal}250 kg NaI(Tl) DAMA/LIBRA set-up is running at the Gran Sasso National Laboratory of the I.N.F.N.. The first result obtained by exploiting the model independent annual modulation signature for Dark Matter (DM) particles confirms the former DAMA/NaI result. The DAMA/NaI and DAMA/LIBRA data satisfy all the many peculiarities of the DM annual modulation signature; neither systematic effects nor side reactions able to account for the observed modulation amplitude and to contemporaneously satisfy all the several requirements of the DM signature are available. Considering the former DAMA/NaI and the present DAMA/LIBRA data all together (total exposure 0.82 tonxyr), the presence of Dark Matter particles in the galactic halo is supported at 8.2 {sigma} C.L.

Astronomical results from the PRONAOS experiment  

NASA Astrophysics Data System (ADS)

The high sensitivity sub-millimetre observations performed with the French balloon-borne experiment PRONAOS have brought exciting and sometimes unexpected new astronomical results. In particular, they have lead to the first detection of the Sunyaev-Zel'dovich effect in its positive part, toward the galaxy cluster A2163. They also have revealed the existence of cold condensations in different sites of star forming regions and toward thin dust clouds at high galactic latitude. This cannot be explained by the standard dust models currently used and could be interpreted as the existence of fractal dust aggregates. The PRONAOS observations have also evidenced a significant correlation between the dust equilibrium temperature and the spectral emissivity index, which may reflect new quantum processes within the grains specific to low temperatures. These results have raised a number of new questions which will be addressed using future balloon-borne projects such as ELISA and the space mission Planck and Herschel.

The LSND experiment provides evidence for neutrino oscillations from both the primary {bar {nu}}{sub {mu}} {r_arrow} {bar {nu}}{sub e} oscillation search and the secondary {nu}{sub {mu}} {r_arrow} {nu}{sub e} oscillation search. At present, this remains the only evidence for appearance neutrino oscillations and implies that at least one neutrino has a mass greater than 0.4 eV/c{sup 2} and that neutrinos comprise more than 1% of the mass of the universe. The MiniBooNE experiment at Fermilab, which is presently under construction, will provide a definitive test of the LSND results, and if the neutrino oscillation results are confirmed, will make a precision measurement of the oscillation parameters.




An investigation of false positive dosimetry results  

SciTech Connect

The Waste Isolation Pilot Plant (WIPP) is a facility designed for the demonstration of the safe disposal of transuranic waste. Currently, the radiation source term is confined to sealed calibration and check sources since WIPP has not received waste for disposal. For several years the WIPP Dosimetry Group has operated a Harshaw Model 8800C reader to analyze Harshaw 8801-7776 thermoluminescent cards (3 TLD-700 and 1 TLD-600) with 8805 holder. The frequency of false positive results for quarterly dosimeter exchanges is higher than desired by the Dosimetry Group management. Initial observations suggested that exposure to intense ambient sunlight may be responsible for the majority of the false positive readings for element 3. A study was designed to investigate the possibility of light leaking through the holder and inducing a signal in element 3. This paper discusses the methods and results obtained, with special emphasis placed on recommendations to reduce the frequency of light-induced false positive readings.

[Carotid surgery, indications, results and perspectives].  


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

First results of Soret Coefficient Measurement Experiment  

NASA Astrophysics Data System (ADS)

The scope of the Soret Coefficient Measurement Experiment (SCM) is to measure the Soret coefficient in 20 binary organic mixtures and aqueous solutions. Because of the limited mass and power budget, this can be considered as a difficult technical challenge. It has been performed in the Solution Growth Facility in non fully nominal conditions and this has an impact on the accuracy of the measurements obtained as discussed in this presentation. However, the high values obtained for the species segregation in microgravity give very valuable results. They allow for a better understanding of ground based measurements and a definition, using the SCM results as standards, of the best technique to be used. The values of the Soret coefficients will be used in the investigation of the role of the Soret effect in interfacial instabilities (Marangoni-Benard instabilities in binary mixtures), on morphological instabilities of a planar solidification front and striations and on the buoyancy induced instabilities (Rayleigh-Benard instabilities).

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.

The OPAL code was developed to calculate the wide range of frequency-dependent and mean opacity data needed to model laboratory experiments and stellar interiors. We use parametric potentials to generate vastly more atomic data than used in earlier opacity work for all elements with atomic number less than 35. We have also developed an improved equation of state based on an activity expansion of the grand canonical partition function. We give herein a brief description of the OPAL code and present new results that include the effect of additional heavy elements compared to our earlier carbons. The importance of very heavy elements having atomic number greater than 30 is also discussed. We present some comparisons with recent results from the Opacity Project and some directions for future work.

Ferrofluid deformable mirrors: recent advances and results  

NASA Astrophysics Data System (ADS)

Many technical improvements have been made since we first introduced deformable mirrors that use magnetic liquids (ferrofluids) whose surface are shaped by arrays of small electric coils. We present recent advances and experimental results of a 91-actuator magnetic liquid deformable mirror that uses a novel technique that linearizes their response by placing the array of actuators inside a strong and uniform magnetic field. We show that this improved ferrofluid deformable mirror (FDM) can produce inter-actuator strokes of over 10 ?m, is capable of generating wavefront having peak-to-valley amplitudes of over 60 ?m, and predict that amplitudes greater than 100 ?m are achievable. We also present experimental results showing that these improved FDMs are good candidates for astronomical, vision science, and optical testing applications.

Dynamic Clustering of Web Search Results

A problem in Web searches is how to help users quickly find useful links from a long list of returned URLs. Document clustering\\u000a provides an approach to organize retrieval results by clustering documents into meaningful groups. Because a word in a document\\u000a is naturally correlated with neighboring words, document clustering often uses phrases rather than individual words in determining\\u000a clusters.

Vector meson electroproduction: recent results and universality  

SciTech Connect

In a nonperturbative approach we have made extensive and comprehensive calculations of the processes of vector meson electroproduction. We here confront our results with recent data on the elastic processes of {rho} and {phi} electroproduction. The description is unified for all vector mesons, without free parameters, covering 5 scales of magnitude in cross sections, exhibiting a universality that is determined by properties of the overlap of photon and vector meson wave functions.

Emulating AOGCM results using simple climate models  

NASA Astrophysics Data System (ADS)

Three simple climate models (SCMs) are calibrated using simulations from atmosphere ocean general circulation models (AOGCMs). In addition to using two conventional SCMs, results from a third simpler model developed specifically for this study are obtained. An easy to implement and comprehensive iterative procedure is applied that optimises the SCM emulation of global-mean surface temperature and total ocean heat content, and, if available in the SCM, of surface temperature over land, over the ocean and in both hemispheres, and of the global-mean ocean temperature profile. The method gives best-fit estimates as well as uncertainty intervals for the different SCM parameters. For the calibration, AOGCM simulations with two different types of forcing scenarios are used: pulse forcing simulations performed with 2 AOGCMs and gradually changing forcing simulations from 15 AOGCMs obtained within the framework of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. The method is found to work well. For all possible combinations of SCMs and AOGCMs the emulation of AOGCM results could be improved. The obtained SCM parameters depend both on the AOGCM data and the type of forcing scenario. SCMs with a poor representation of the atmosphere thermal inertia are better able to emulate AOGCM results from gradually changing forcing than from pulse forcing simulations. Correct simultaneous emulation of both atmospheric temperatures and the ocean temperature profile by the SCMs strongly depends on the representation of the temperature gradient between the atmosphere and the mixed layer. Introducing climate sensitivities that are dependent on the forcing mechanism in the SCMs allows the emulation of AOGCM responses to carbon dioxide and solar insolation forcings equally well. Also, some SCM parameters are found to be very insensitive to the fitting, and the reduction of their uncertainty through the fitting procedure is only marginal, while other parameters change considerably. The very simple SCM is found to reproduce the AOGCM results as well as the other two comparably more sophisticated SCMs.

[Fate of the results of research projects].  


Once completed, the results of a research project must be made known to the scientific community. This is usually achieved by presentations at scientific meetings or by publishing the results in a journal of the specialty. The purpose is not only to make public these findings, but that they can be used to solve problems, immediately or in the long-term, or to serve as the basis for future research. However, several studies have found that less than 50% of the communications to congresses are published. One of the main reasons is that publications in high impact journals can not be easily attained since most of them are not of open access. For this reason, it is convenient to resort to free-access journals listed in prestigious international indexes. The Council for Scientific Development at the University of Zulia financially supports a number of scientific journals that meet these criteria. If the research was the result of a PhD, Master or Specialty thesis or the project for a promotion in an academic institution, the end result should be also their publication; but commonly, these are even less published than communications to scientific meetings. At the University of Zulia, Serbiluz has made a major effort to collect all this material and make it available to serve the scientific community. It is necessary to mention that the institution that supports financially a research project has the right to demand its publication, to benefit the greatest number of people and as a mean to compensate the economic support with scientific knowledge.

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.

The results of radiotherapy for Hodgkins' disease.  


The results of radiation therapy in 212 patients with stages I and II Hodgkin's disease treated between 1963 and 1973 show that approximately 60% remain disease-free following treatment. Multiple node involvement in stage II, particularly associated with infraclavicular node disease, is identified as a group where the relapse rate is high. This presentation is associated particularly with NS. In a group of 78 patients treated with radiotherapy following staging laparotomy and splenectomy approximately 80% remain in complete remission. The preliminary results of treatment in PS IIIa patients are substantially the same as those for PS I and II; the results of treatment for NS and MC disease are similar. The significance of involvement of the spleen is discussed. Although it is probable that Hodgkin's disease spreads to the spleen through the blood stream it is suggested that splenic involvement does not necessarily indicate that the involvement of other extralymphatic structures such as liver and marrow has occurred. However, when the nodes in the porta hepatis are involved splenic Hodgkin's disease may well be associated with an increased risk of occult hepatic infiltration. PMID:1233084

Laparoscopic (endoscopic) radical prostatectomy: techniques and results  

NASA Astrophysics Data System (ADS)

Laparoscopic radical prostatectomy (LRP) is a relatively new technique for treating organ-confined prostate cancer. Recent progress of laparoscopic/endoscopic techniques allow to perform these complex oncological procedure. Since the first description of LRP in the early 1990s the technique has undergone significant technical modifications. Two operation routes were mainly used: the transperitoneal LRP and the extraperitoneal endoscopic radical prostatectomy (EERPE). Here we review the surgical techniques of both operation routes, and highlight results, outcome and complications. The transperitoneal LRP and the EERPE can be used successfully and reproducibly, giving results comparable with those from the open retropubic procedure. Despite many advantages, transperitoneal LRP is associated with potential intraperitoneal complications. The technical improvements of the EERPE completely obviates these complications. The available data are encouraging and promising, but long-term oncological results will define the definitive role of these new techniques. We truly believe that minimally invasive surgery in treating localized prostate cancer has a bright future and that these techniques will continue to be developed.

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.

Posterior endoscopic discectomy: Results in 300 patients  

PubMed Central

Background: Posterior endoscopic discectomy is an established method for treatment of lumbar disc herniation. Many studies have not been reported in literature for lumbar discectomy by Destandau Endospine System. We report a series of 300 patients operated for lumbar dissectomy by Destandau Endospine system. Materials and Methods: A total of 300 patients suffering from lumbar disc herniations were operated between January 2002 and December 2008. All patients were operated as day care procedure. Technique comprised localization of symptomatic level followed by insertion of an endospine system devise through a 15 mm skin and fascial incision. Endoscopic discectomy is then carried out by conventional micro disc surgery instruments by minimal invasive route. The results were evaluated by Macnab's criteria after a minimum followup of 12 months and maximum up to 24 months. Results: Based on modified Macnab's criteria, 90% patients had excellent to good, 8% had fair, and 2% had poor results. The complications observed were discitis and dural tear in five patients each and nerve root injury in two patients. 90% patients were able to return to light and sedentary work with an average delay of 3 weeks and normal physical activities after 2 months. Conclusion: Edoscopic discectomy provides a safe and minimal access corridor for lumbar discectomy. The technique also allows early postoperative mobilization and faster return to work.

The MATROSHKA Experiment - First Mission Results  

NASA Astrophysics Data System (ADS)

MATROSHKA is an ESA multi-user experiment unit on the International Space Station ISS for studies of depth dose distribution of the different components of the orbital radiation field at different sites of the organs, occurring in astronauts being exposed during an EVA. To accomplish that, the facility comprises an anthropomorphic phantom to simulate the human body, active and passive detectors for space radiation dosimetry, data acquisition and processing electronics and the overall mechanical housing and support structure for the MATROSHKA components. The development and manufacture was under ESA contract by DLR, Institute for Aerospace Medicine with sub-contractors Kayser Italia (Livorno) and DTM (Modena). MATROSHKA was launched within PROGRESS on January 29, 2004 and mounted shortly afterwards outside the Russian Zvezda Module of the Station. The time of outside exposure during this mission phase was 539 days. After that, the facility was returned into the Station for passive sensor exchange. After the first passive detector set was returned to ground with Soyuz for on-ground evaluation the facility is further used inside the station during two follow-on project phases. The MATROSHKA experiment delivered a unique set of data results from the evaluation of numerous detectors, such as Thermoluminescence detectors, plastic nuclear track detectors and silicon dosemeters. This paper intends to give besides a short overview of the instrumentation used inside the MATROSHKA facility selected results from the first exposure and describes the determination of organ dose equivalents from these results

[Relaxing retinectomy: anatomic and functional results].  


The author analyzed the results of relaxing retinectomy (RR) combined with internal tamponade of the retina by silicone oil in 50 patients. The causes of tractional detachment and shortening of the retina were: proliferative vitretinopathy complicating idiopathic rhegmatogenic detachment of the retina in 25 eyes, proliferative diabetic retinopathy in 12 eyes, post-traumatic proliferation in seven eyes, intraocular inflammation in four eyes and the cicatricial stage of retinopathy of the premature in two eyes. During an observation period of 6-75 months, mean 17 months, the authors recorded complete adherence of the retina in 60%, partial anatomical success with defined retinal detachment and adherent macula in 24% and functional success with visual acuity of 0.02 or better in 66%. The poorest functional results were obtained in proliferative diabetic retinopathy (success in 30%). Functional success declined with the observation period from 66% 6 months after RR to 38% after 36 months following RR. The extent of RR did not have a substantial effect on the anatomical and functional results. Sufficiently extensive RR with internal tamponade of the retina with silicone oil is the operation of choice in complicated retinal detachment where radical membranectomy does not release the retinal traction. Reproliferation after RR were the frequent causes of relapses of retinal detachment and an impediment for removal of silicone oil from the eye. PMID:7805114

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.

False positive tuberculosis skin test results.  

PubMed Central

The re-emergence of tuberculosis as a significant public health threat has led to greatly renewed activity in tuberculin skin testing to identify infected persons. However, even use of the preferred skin test technique (intradermal injection of purified protein derivative via the Mantoux method) can lead to either false positive or false negative results. Interpretation of a Mantoux test can be influenced by cross reactions with other mycobacteria, intertester variation, host-response variation, and product related problems. At least 25 apparent false positive purified protein derivative skin test reactions in New York State in 1992 appeared to be associated with lots of the derivative produced by one manufacturer. These unexpected skin test results led to examination of a product with an altered appearance that may have caused the unanticipated responses. After announcement of these false positive results to the press, the company removed the product from the market. Food and Drug Administration analysis later revealed particulate matter in vials of the suspected lots of purified protein derivative.

Deuteron photodisintegration : new results from TJNAF.  

SciTech Connect

The first measurements of the differential cross section from d({gamma},p)n up to 4.0 GeV were performed at the Thomas Jefferson National Accelerator Facility (TJNAF, formerly CEBAF). Bremsstrahlung photons from electron beam impinging on a copper radiator and a liquid deuterium target were employed for this experiment. The experiment was performed in Hall C where the photoprotons at forward angles in the center-of-mass were detected in the High Momentum Spectrometer (HMS) and photoprotons at backward angles were detected in the Short Orbit Spectrometer (SOS). The bremsstrahlung photon energy was reconstructed from the measured proton momentum and angle using the two-body kinematics. We report the cross section results at the proton center-of-mass angles of 37{degree} and 90{degree}. These results are in good agreement with previous lower energy measurements. The 90{degree} data continue to show the constituent-counting-rule behavior up to 4 GeV. The results will be compared with models based on QCD as well as those based on meson-exchange theory.

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.

[Results of regeneration after peripheral nerve injuries].  


Based on a group of distal injuries of the median and ulnar nerve the authors evaluate the results of peripheral nerve regeneration. For evaluation of the results and comparison with other work they emphasize the necessity of adherence to objective criteria of a useful degree of reinnervation. In their opinion the most suitable criterium is evaluation of sensitive reinnervation respecting the discrimination test up to 12 mm in the entire autozone of the nerve. The results of suture depend on the technique, interval (injury-operation) and the patient's age. In acute operations 45% of the patients of all age groups achieved the useful grade of sensitive regeneration. In late operations, where the degree of useful regeneration was achieved only in 19% of patients, the authors draw attention to the fact that a successful outcome was achieved only in patients under 30 years. The main prerequisite of successful regeneration of peripheral nerves in according to the authors early diagnosis and treatment in the acute period. With regard to the declining regeneration potential with advancing age early treatment is much more important in patients older than 30 years. Microsurgical technique is a condition sine qua non.

SCEC Earthquake Simulator Comparison Results for California  

NASA Astrophysics Data System (ADS)

This is our first report on comparisons of earthquake simulator results with one another and with actual earthquake data for all of California, excluding Cascadia. Earthquake simulators are computer programs that simulate long sequences of earthquakes and therefore allow study of a much longer earthquake history than is possible from instrumental, historical and paleoseismic data. The usefulness of simulated histories for anticipating the probabilities of future earthquakes and for contributing to public policy decisions depends on whether simulated earthquake catalogs properly represent actual earthquakes. Thus, we compare simulated histories generated by five different earthquake simulators with one another and with what is known about actual earthquake history in order to evaluate the usefulness of the simulator results. Although sharing common features, our simulators differ from one another in their details in many important ways. All simulators use the same fault geometry and the same ~15,000, 3x3 km elements to represent the strike-slip and thrust faults in California. The set of faults and the input slip rates on them are essentially those of the UCERF2 fault and deformation model; we will switch to the UCERF3 model once it is available. All simulators use the boundary element method to compute stress transfer between elements. Differences between the simulators include how they represent fault friction and what assumptions they make to promote rupture propagation from one element to another. The behavior of the simulators is encouragingly similar and the results are similar to what is known about real earthquakes, although some refinements are being made to some of the simulators to improve these comparisons as a result of our initial results. The frequency magnitude distributions of simulated events from M6 to M7.5 for a 30,000 year simulated history agree well with instrumental observations for all of California. Scaling relations, as seen on plots of slip vs. rupture length, magnitude vs. rupture area, and magnitude vs rupture length, are similar for the different simulators. On these plots, overlaying results from several studies characterizing actual earthquake scaling shows good agreement with the simulator results. Importantly, moment rates and event rates for M7+ events show variations by factors of 3 in 100-yr moving averages throughout the 30,000 year simulated histories, with event rates for M6+ events correlating with M7+ event rates and 200 year periods being too short to characterize the moment and event rates. This suggests that in California our observational instrumental and historical record is too short to characterize seismicity rates adequately. For fault sections where paleoseismic data exist to constrain interevent times, fault stress drops assumed by the simulators can be adjusted to agree with observations. Lacking constraining data the simulated interevent times may be off, perhaps by up to a factor of 2.

Result of recent weatherization retrofit projects  

SciTech Connect

Pacific Gas and Electric (PG and E) and the Bonneville Power Administration (BPA) have conducted studies in their respective service areas in order to evaluate the cost-effectiveness of certain conservation retrofits. Twenty houses in Walnut Creek, California, underwent an infiltration reduction program, similar to house doctoring. Ten of these houses also received additional contractor-installed measures. BPA retrofitted 18 houses at its Midway substation in central Washington. Retrofits made to the houses included: attic and crawlspace insulation, foundation sill caulking, storm windows and doors, increased attic ventilation, and infiltration reduction. Energy consumption and weather data were monitored before and after each set of retrofits in both projects. Leakage measurements were made by researchers from the Energy Efficient Buildings Program using blower door fan pressurization, thereby allowing calculation of heating season infiltration rates. An energy use model correlating energy consumption with outside temperature was developed in order to determine improvements to the thermal conductance of the building envelope as a result of the retrofits. Energy savings were calculated based on the results of the energy use model. As a check on these findings, the Computerized Instrumented Residential Audit (CIRA) load calculation program developed at Lawrence Berkeley Laboratory provided a theoretical estimate of the savings resulting from the retrofits. At Midway, storm windows and doors were found to save the most energy. Because the Midway houses were not very leaky at the beginning of the experiment, the infiltration reduction procedures were less effective than expected. In the Walnut Creek project, the infiltration reduction procedures did decrease the leakiness of the test houses, but the effect upon energy savings was not great.

Mass Media Release of Medical Research Results  

PubMed Central

BACKGROUND Disclosure of medical research results to the public creates tension between lay medical reporters and the medical profession. OBJECTIVE To explore the early effect of media attention on the risks associated with short-acting calcium channel blockers (CCBs) for treating hypertension after publication at a national meeting and following publication. DESIGN Time-series analysis of prescription claims data. SETTING AND DATA SOURCE National third-party pharmaceutical benefits manager. PATIENTS Employed or retired persons and their families, 18 years of age or older, receiving prescription benefits from 1 of 4 national companies that contracted with the pharmaceutical benefits manager exclusively for prescription drug coverage. MEASUREMENTS Prescription claims for antihypertensive drugs by fill date converted to a percentage of all cardiovascular drug claims. Data were grouped into weekly intervals before and immediately after the national release of negative information about CCBs on March 10, 1995 and following publication of the results on August 23, 1995. RESULTS The most prevalent antihypertensive drugs were diuretics (21% of cardiovascular prescription claims) and calcium channel blockers (19%). A 10% decline in prescriptions filled for CCBs occurred 4 weeks following the intense media attention. Only prescriptions for long-acting calcium channel blockers declined. Alpha-1-blocker prescriptions increased by approximately the same amount that prescriptions for CCBs declined, suggesting substitution of one drug for the other. Changes in diuretic or ?-blocker prescriptions filled were not statistically significant. No immediate change in other cardiovascular drug classes occurred following journal publication. CONCLUSIONS Intense media publicity regarding a controversial study measurably and unpredictably changed prescription claims.

Good results with the Ponseti method  

PubMed Central

Background and purpose In 2002–2003, several hospitals in Norway introduced the Ponseti method for treating clubfoot. The present multicenter study was conducted to evaluate the initial results of this method, and to compare them to the good results reported in the literature. Patients and methods 116 children with 162 congenital idiopathic clubfeet who were born between 2004 and 2006 were treated with the Ponseti method at 8 hospitals in Norway. All children were prospectively registered at birth, and 116 feet were assessed according to Pirani before treatment was started. 63% used a standard bilateral foot abduction brace, and 32% used a unilateral above-the-knee brace. One of the authors examined all feet at a mean age of 4 years. At follow-up, all feet were assessed by Pirani’s scoring system, and range of motion of the foot and ankle was measured. Results At follow-up, 77% of the feet had a Pirani score of 0.5 or better, good dorsiflexion and external rotation, and no forefoot adduction. An Achilles tenotomy had been performed in 79% of the feet. Compliance to any brace was good; only 7% were defined as non-compliant. Extensive soft tissue release had been performed in 3% of the feet. We found no statistically significant differences between the two braces, except a tendency of better Pirani score in the group using the bilateral foot abduction brace, and a tendency of better compliance in patients using the unilateral brace. Better Pirani scores were found in children who were treated at the largest hospitals. Interpretation After introducing the Ponseti method in Norway, the clinical outcome was good and in accordance with the reports from single centers. Only 5 feet needed extensive surgery during the first 4 years of life.



September 2007 monitoring results for Centralia, Kansas.  

SciTech Connect

In September 2005, periodic sampling of groundwater was initiated by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in the vicinity of a grain storage facility formerly operated by the CCC/USDA at Centralia, Kansas. The sampling at Centralia is being performed on behalf of the CCC/USDA by Argonne National Laboratory, in accord with a monitoring program approved by the Kansas Department of Health and Environment (KDHE). The objective is to monitor levels of carbon tetrachloride contamination identified in the groundwater at Centralia (Argonne 2003, 2004, 2005a). Under the KDHE-approved monitoring plan (Argonne 2005b), the groundwater is being sampled twice yearly (for a recommended period of two years) for analyses for volatile organic compounds (VOCs), as well as measurement of selected geochemical parameters to aid in the evaluation of possible natural contaminant degradation (reductive dechlorination) processes in the subsurface environment. The sampling is presently conducted in a network of 10 monitoring wells and 6 piezometers (Figure 1.1), at locations approved by the KDHE (Argonne 2006a). The results of groundwater sampling and VOCs analyses in September-October 2005, March 2006, September 2006, and March 2007 were documented previously (Argonne 2006a,b, 2007a). The results have demonstrated the presence of carbon tetrachloride contamination, at levels exceeding the KDHE Tier 2 Risk-Based Screening Level of 5 {micro}g/L for this compound, in a broad groundwater plume that has shown little movement. This report presents the results of the groundwater sampling at Centralia in September 2007, performed in accord with the KDHE-approved monitoring plan (Argonne 2005b). The September 2007 sampling represents the fifth and final monitoring event performed under the recommended two-year monitoring program approved by the KDHE.

Favorable results after total wrist arthroplasty  

PubMed Central

Background and purpose During the past 40 years, several attempts have been made with total wrist arthroplasty to avoid fusion in severely destroyed wrists. The results have often been disappointing. There is only modest clinical documentation due to the small number of patients (especially non-rheumatoid cases) and short follow-up times. Here we report a multicenter series using a third-generation implant with a minimum follow-up time of 5 years. Methods In 2012, data were retrieved from a registry of consecutive wrist operations at 7 centers with units specialized in hand surgery, between 2003 and 2007. The wrists had been reviewed annually and analysis was done on the latest follow-up data. Results 60 patients had been operated (5 bilaterally), 5 wrists had been revised, and 52 were available for follow-up (with the revised cases excluded). The pain scores, QuickDASH scores, ulnar flexion, and supination for the whole group were statistically significantly better at follow-up. There were no statistically significant differences between the rheumatoid and the non-rheumatoid patients except for motion, which was better in the non-rheumatoid group. The motion obtained depended on the preoperative motion. Implant survival was 0.9 at 5–9 years. Interpretation The clinical results in terms of pain, motion, strength, and function were similar to those in previous reports. The implant survival was 0.9 at 9 years, both in rheumatoid and non-rheumatoid cases, which is an important improvement compared to the earlier generations of total wrist arthroplasty.

Seeding cumulus in Florida: new 1970 results.  


In the Florida single cloud experiments, the main result of the statistical analyses is that the dynamic seeding effect on rainfall is large, positive, and significant. From all the 1968 and 1970 data together, the seeding effect is estimated to be larger than a factor of 3; that is, the seeded clouds rained more than three times as much as the controls after the seeding run. On fair days, defined objectively by percentage of area covered by showers, the seeding effect is shown to be larger than the overall average, but it may be negative on rainy days. Rainy days in the tropics are about 10 percent of the days with rain, but they produce about half the total rainfall. The applicability of our single cloud results to other areas is not established but seems hopeful for many tropical and subtropical regions. It can be assessed by cloud population studies together with our numerical model (25). Guidance for the next steps toward practical rainfall enhancement and toward the understanding and modification of cloud systems in storms may be provided by our study of merger clouds. Mergers are shown often to produce more than an order of magnitude more rain than isolated clouds on the same day, probably owing to dynamic invigoration of the merged cloud circulations. Results of our first small attempt toward inducing and documenting mergers in a multiple cloud seeding experiment appear promising. Although far from statistically conclusive, they have opened a new frontier in the science and technology of dynamic cloud modification. It is also hoped that the multiple cumulus seeding experiments will help to clarify the formation of "cloud clusters" and their role in large-scale circulations, thus contributing to the focal subject of the Global Atmospheric Research Program in the tropics.

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.

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.

Results with navigated bicontact total hip arthroplasty.  


The position of the cup is crucial for the overall quality of a total hip arthroplasty. A malpositioning of the cup leads to increased risk of dislocation, wear, and revision. The position of the stem influences leg length and may cause impingement and dislocation. These faults may increase with minimally invasive procedures. From November 2001 to June 2005, 1081 consecutive THA patients were evaluated. Cup navigation resulted in a better alignment and additional improvement when the cup and stem were navigated. In stem navigation, a good control of the leg lengthening and a reliable prediction of the safe range of motion could be seen. PMID:16235445

Polarized electron beams can play an important role in the dynamics of interactions at high energies. Polarized electron beams at SLAC have been an important part of the physics program since 1970, when they were first proposed for use in testing the spin structure of the proton. Since 1992, the SLAC linear accelerator and the SLC have operated solely with polarized electrons, providing data for tests of QCD in studies of the spin structure of the nucleon and tests of the electroweak sector of the Standard Model. In the following sections, the performance of the source is summarized, and some of the recent results using the polarized beams are discussed.

Complex craniofacial trauma resulting from fireworks blast.  


The authors report the case of a patient who sustained a complex craniofacial trauma secondary to a recreational fireworks blast. Initial assessment and management were performed with a multidisciplinary approach to achieve control of cerebral hemorrhage, debridement of wounds and brain, isolation of the brain from the external environment, reconstruction of the cranial base floor, and orbital and facial reconstruction. Modification of multiple conventional approaches, along with a multispecialty surgical team, were used to deal effectively with this unusual patient who was treated by single-stage immediate management. Reconstruction of both the intracranial and extracranial compartments was considered successful with a satisfactory cosmetic result. PMID:18362706

Spaceflight results in formation of defective bone.  


Growing rats were flown on 19 day spaceflights aboard Cosmos 782 and 936 biosatellites. Spaceflight resulted in a prominent skeletal defect at the periosteal surface of the tibia diaphysis. The defect, termed an arrest line, was approximately 3 micron across and separated the bone formed in space from that formed following spaceflight. The bone matrix at the arrest line region was abnormal in that collagen fibers were preferentially orientated parallel to the periosteal surface. In addition, the bone matrix was hypomineralized. The altered bone was inferior to normal bone in resistance to abrasion and may be partially responsible for the decrease in torsional strength observed after spaceflight. PMID:4080703

The UltraViolet/Optical Telescope on Swift is a 30-cm Richey-Cretien reflector that provides sub-arcsecond positions, light curves on time scales from minutes to days after a GRB, and spectra covering 160 - 700 nm. UVOT is detecting optical afterglows from ~67% of rapidly observed long GRBs that have little extinction in the Milky Way. We consider possible reasons for the non-detections. UVOT is also producing remarkable results on the evolution of GRB afterglows including GRB060218/SN2006aj as well as the evolution of young supernovae.

(Abstract only) The Z CamPaign is an observing project designed to acquire enough detailed, long-term data to unambiguously classify dwarf novae as bona fide members of the Z Cam sub-type or not. Because the defining characteristic of all Z Cam dwarf novae are "standstills," a temporary period of relative quiet between maximum and minimum light, we are monitoring these systems for this specific activity. Amateur astronomers are gathering all the data with backyard telescopes as part of an AAVSO Cataclysmic Variable Section observing initiative. We will discuss the organization, science goals, and present early results of the Z CamPaign.

The Apollo SWC Experiment: Results, Conclusions, Consequences  

NASA Astrophysics Data System (ADS)

The Apollo Solar Wind Composition (SWC) experiment was designed to measure elemental and isotopic abundances of the light noble gases in the solar wind, and to investigate time variations in the solar-wind composition. The experiment was deployed on the first five Apollo lunar landing missions. The crews exposed a foil at each of the five landing sites, and solar wind particles were collected for time periods ranging from 77 minutes in July 1969 (Apollo 11) to 45:05 hours in April 1972 (Apollo 16). The foils were returned to Earth, where the collected noble gas particles were analysed in ultra-high vacuum mass spectrometer systems. We briefly describe here the flight hardware, and the technical tests and calibrations. The experimental results were published in various scientific journals, PhD theses and NASA science reports, some of them not readily accessible after three decades. In this paper, therefore, the results obtained by the five experiments on the fluxes of the isotopes of He, Ne and Ar are summarized and discussed, so that averages and variations in solar wind composition can be more easily compared with more recent data, particularly those to be obtained by the Genesis mission. The helium flux determined for the five exposure periods varied by a factor of four, with a time-weighted average of 1.2 × 107 cm-2 s-1. Although the composition varied much less than the He-flux, definite variations were found for the 4He/3He and He/Ne ratios. The weighted average solar wind abundance ratios obtained were 4He/3He = 2350 ± 120, 4He/20Ne = 570 ± 70, 20Ne/22Ne = 13.7 ± 0.3, 22Ne/21Ne = 30 ± 3, 20Ne/36Ar = 49 ± 7 and 36Ar/38Ar =5.4 ± 0.3 (errors correspond to the 2? level). We also measured the flow directions of individual isotopic species. We found that the lunar environment did not significantly affect the solar wind composition measured at the lunar surface, and we conclude that the SWC results are representative of the solar wind prevailing in interplanetary space at the time of the five foil exposures. Finally, we discuss, from today's perspective, some of the implications and conclusions that can be drawn from the SWC results, concerning the Sun and its history, the solar system, the galaxy and the universe.

Superconducting solenoid model magnet test results  

SciTech Connect

Superconducting solenoid magnets suitable for the room temperature front end of the Fermilab High Intensity Neutrino Source (formerly known as Proton Driver), an 8 GeV superconducting H- linac, have been designed and fabricated at Fermilab, and tested in the Fermilab Magnet Test Facility. We report here results of studies on the first model magnets in this program, including the mechanical properties during fabrication and testing in liquid helium at 4.2 K, quench performance, and magnetic field measurements. We also describe new test facility systems and instrumentation that have been developed to accomplish these tests.

B-Physics results from D0  

NASA Astrophysics Data System (ADS)

We report on preliminary measurements of the inclusive single muon and dimuon cross sections in p(bar p) collisions at (radical)s = 1.8 TeV using the D0 detector at the Fermilab collider. From these results, we extract the cross section for b-quark production for the kinematic range (vert bar)yb(vert bar) less than 1.0 and 6 less than p(sub t)(sup b) less than 50 GeV/c. We also report measurements on the J/(psi) production, and correlations between muons in dimuon events.

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.

Caloric testing 2. results in normal subjects.  


A large number of variables were examined simultaneously for 43 normal subjects over the four irrigations of a caloric test. Care was used for every step of the testing procedure and data analysis to eliminate as much of the variance in the caloric responses as possible. The normality of each variable's distribution was examined using the Wilk-Shapiro W test and corrected if necessary by the best of several transformations. The means, standard deviation, and 95% confidence intervals of the resultant data were derived. Statistical tests of temperature, sidedness, and directionality were done on the variables and several important sources of variance were found and explained. PMID:410352

New diffractive results from the Tevatron  

SciTech Connect

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.

Exact results for the Barabási queuing model.  


Previous works on the queuing model introduced by Barabási to account for the heavy tailed distributions of the temporal patterns found in many human activities mainly concentrate on the extremal dynamics case and on lists of only two items. Here we obtain exact results for the general case with arbitrary values of the list length L and of the degree of randomness that interpolates between the deterministic and purely random limits. The statistically fundamental quantities are extracted from the solution of master equations. From this analysis, scaling features of the model are uncovered. PMID:19905297

Global Imager (GLI) is the visible to infrared imager aboard ADEOS-II satellite with 30 and 6 channels for 1 km and 250m resolutions, respectively. The sensor was successfully captured the first image on January 25, 2003. Sea surface temperature (SST) will be retrieved in combination with simultaneous SST observation by low-resolution microwave sensor, AMSR-E. Distribution of chlorophyll and other constituents will be obtained from ocean color channels. Frequent observations with 250 m visible channels will be also available, and combination with 1 km ocean color and SST will be useful for coastal applications. Early scientific results of GLI ocean group will be presented in this presentation.

Enhancing results of microarray hybridizations through microagitation.  


Protein and DNA microarrays have become a standard tool in proteomics/genomics research. In order to guarantee fast and reproducible hybridization results, the diffusion limit must be overcome. Surface acoustic wave (SAW) micro-agitation chips efficiently agitate the smallest sample volumes (down to 10 microL and below) without introducing any dead volume. The advantages are reduced reaction time, increased signal-to-noise ratio, improved homogeneity across the microarray, and better slide-to-slide reproducibility. The SAW micromixer chips are the heart of the Advalytix Array-Booster, which is compatible with all microarrays based on the microscope slide format. PMID:13678150

Tracking results using a standard cell lattice  

SciTech Connect

This is a summary of results obtained by tracking a single particle through a lattice composed of a r.f. cavity and standard FODO cells. The lattice also includes two families of sextupoles for controlling the chromaticity. The parameters of the cells, i.e. their length and phase advance, closely resemble those of the Fermilab Main Ring or the Tevatron. We therefore have a model lattice which is similar to that of those accelerators but without the straight sections present in the actual machines. It is hoped that the simplified model used will exhibit the salient features of the actual accelerator but will be simpler to understand. 8 figs., 1 tab.

The Tevatron at Fermilab continues to collect data at high luminosity resulting in datasets in excess of 6 fb{sup -1} of integrated luminosity. The high collision energies allow for the observation of new heavy quark baryon states not currently accessible at any other facility. In addition to the ground state {Lambda}{sub b}, the spectroscopy and properties of the new heavy baryon states {Omega}{sub b}, {Xi}{sub b}, and {Sigma}{sub b}{sup (*)} as measured by the CDF and D0 Collaborations are presented.

CO-OP DOE foundry process results  

NASA Astrophysics Data System (ADS)

The DARPA-funded Consortium for Optical and Optoelectronic Technologies for Computing (CO-OP) recently completed the first DOE Foundry run delivering ten samples to each of nineteen users, each with a unique design. The binary optics process was used to provide a maximum of eight phase levels at a design wavelength of 850 nm. Averaged over all users and all samples, an etch depth error of one percent and alignment accuracy within 0.25 micron were achieved. This paper summarizes the details of the process results.

Recent Results and Future Prospects from MINOS  

SciTech Connect

The MINOS experiment uses the intense NuMI beam created at Fermilab and two magnetized tracking calorimeters, one located at Fermilab and one located 735 km away at the Soudan Mine in Minnesota, to make precise measurements of {nu}{sub {mu}} disappearance oscillation parameters. We present recent results from the first two years of NuMI beam operations, including the precise measurement of the atmospheric neutrino oscillation parameters and the search for sterile neutrinos. Future prospects for MINOS will also be discussed, including an improved limit on the {theta}{sub 13} mixing angle by searching for {nu}{sub e} appearance in the {nu}{sub {mu}} beam.

Exact results for supersymmetric. sigma. models  

SciTech Connect

We show that the metric and Berry's curvature for the ground states of {ital N}=2 supersymmetric {sigma} models can be computed exactly as one varies the Kahler structure. For the case of CP{sup {ital n}} these are related to special solutions to affine Toda equations. This allows us to extract exact results. We find that the ground-state metric is nonsingular as the size of the manifold shrinks to zero, suggesting that 2D quantum field theory makes sense even beyond zero radius. Thus it seems that manifolds with zero size are nonsingular as target spaces for string theory (even when they are not conformal).

Heavy baryons - Recent and very new results  

SciTech Connect

Recent results on observations, properties and decay modes of the charmed and beauty baryons will be reviewed. Candidates for several new high mass states which include a cleanly-identified daughter {Lambda}{sub c}{sup +} baryon are seen in data from the SELEX experiment at Fermilab. These states are candidates for doubly-charmed baryons: a {Xi}{sub cc}{sup ++} state and a {Xi}{sub cc}{sup +} state. These candidates are more than 5{sigma} signals in each case at masses of 3520 and 3460 MeV respectively.
