  3. Pediatric uses of In-111 WBC imaging

    International Nuclear Information System (INIS)

    To evaluate the diagnostic efficacy of In-111 WBC imaging in pediatrics the authors have examined the records of children seen in the laboratory. During the past 4 years they have performed 45 pediatric In-111 WBC studies, half within 1984 alone, in 40 children aged one month to 20 years. In children under one year old they have labelled WBC from 5-10 cc. of the child's blood. They have preferred to transfuse infants after withdrawal of the blood for labelling rather than label donor blood. In twelve children (30%) there was diagnostic localization of labelled WBCs. Five children had equivocal results while three had distinct but false positive localization. The confusing effect of skin lesions of chicken pox and of lymphadenopathy was apparent in six patients. Thirteen children had normal studies. Overall this study of utilization of In-111 WBC in pediatrics suggests best utilization in colitis and abdominal and pelvic infections and in osteomyelitis, especially in distinguishing osteomyelitis from bone infarcts in sickle cell disease. There appears to be lesser utility in patients with palpable adenopathy or superficial infection. Although In-111 WBC imaging may provide clear evidence for active pneumonitis in cases where a chest x-ray is equivocal, such as cytomegalovirus infection, vague localization in bases of lungs, mediastimum or heart is a relatively common finding without known clinical significance

  6. In-111 WBC scintigraphy in adult osteomyelitis

    International Nuclear Information System (INIS)

    Unlike pediatric bone infections, adult osteomyelitis is commonly related to trauma, surgery, or direct extension from an overlying soft tissue infection. Because of this, the findings on Tc-99m MDP bone scintigraphy tend to be nonspecific. Therefore the value of In-111 WBC scintigraphy in the diagnosis of adult osteomyelitis was evaluated. 52 scans were obtained on 51 adult patients who were consecutively referred to the authors' department with this provisional diagnosis. The diagnosis was confirmed by at least two of the following: positive culture, surgery, x-rays, laboratory results, and clinical response to antibiotics. Of the 52 scans studied the sensitivity was 84%, specificity was 82%, and the accuracy was 83%. False positive results occurred most frequently in patients with inflammatory arthritis. False negative examinations occurred in patients who had In-111 WBC concentration in overlying soft tissue obscuring the bony abnormality. Neither the chronicity of the infection, nor prior treatment with antibiotics created difficulty in scan interpretation. It was concluded that although somewhat less sensitive than TcMDP bone scanning, In-111 WBC scintigraphy is more specific than previously studied radiopharmaceuticals in the assessment of bone infections in the adult population

  10. In-111 WBC imaging in musculoskeletal sepsis

    International Nuclear Information System (INIS)

    This study evaluated the accuracy and utility of the In-111 labeled WBC imaging in a series of patients who were suspected of having musculoskeletal sepsis. The labeling of the WBCs was patterned after a method previously described, in which the WBCs are labeled with In-111 oxine in plasma. The WBCs from 100 ml of blood are separated and incubated with In-111 oxine complex, and then 500 μCi. of the labeled cells were reinjected into the patient. Images of the areas in question were obtained at 24 hrs. In some instances, 48 hour images were also obtained. Images were interpreted using consistent criteria. Forty imaging procedures were done on 39 patients. These included 39 total joint protheses, and 17 other images to evaluate possible osteomyelitis, septic arthritis or deep abscesses. Of these studies, 15 were positive, and 42 negative. The findings were then correlated with operative culture and pathology in 21, aspiration cultures and gram stains in 14, and with clinical findings in the remaining 21. This correlation showed 41 true negatives, 12 true positives, 1 false negative, and 2 false positives. The sensitivity was 92.9% and the specificity was 95.2%l. The false negative occurred in a patient on chronic suppressive antibiotic therapy for an infected total hip replacement. The false positive images occurred in a patient with active rheumatoid arthritis and in a patient imaged one month post operative placement of the prosthesis. These images were very useful in several septic patients who had many possible sites of infection. The authors conclude that In-III imaging is an accurate and useful non-invasive method of evaluating musculoskeletal sepsis

    Full Text Available ABSTRACT Introduction & Objective: Pseudomonas aeruginosa is a gram negative bacterial. This bacterium is resistant to many antibiotics and chemical disinfectants. Pseudomonas aeruginosa is an opportunistic bacteria and caused infection in skin, external ear, upper respiratory tract, large intestine and is an important bacteria in nosocomial infections. It causes acute infection in burn disease. This bacterium can produce exotoxin A and effect on elongation factor II and can stop protein synthesis. The aim of this study was to evaluate the effect of exotoxin A on mice WBC and comparison of the results with human WBC that contaminated with Pseudomonas aeruginosa. Materials & Methods: This is an experimental study which was conducted in 1384 on burn disease patients referred to Shiraz Ghotbodin hospital. Sample that contaminated with PA was taken from these patients for WBC count and WBC differentiation. Sample was also taken from 100 burn patients without infection (50 male and 50 female. Toxigenic strain of PA103 was cultured on liquid media and used for purification of exotoxin A. This sample was injected to 50 mice (I.V and after different incubation time, WBC was counted. Ten normal mice was used as control. Collected data analyzed by SPSS. Results: WBC count decreased in mice that received Pseudomonas aeruginosa exotoxin A in comparison with normal mice (P<0.05. WBC count was significantly decreased in burn patients in comparison with normal individuals (P<0.029 and most decrease was belonged to PMN. Conclusion: The results demonstrated that Pseudomonas aeruginosa that produce exotoxin induce WBC decrease in burn disease and also in mice that contaminated with exotoxin of this bacteria. It can be concluded that bacterial infection in burn patients is toxigenic strain of PA that produce exotoxin A.

    Neil M Johannsen

    Full Text Available BACKGROUND: Elevated total white blood cell (WBC count is associated with an increased risk of coronary heart disease and death. Aerobic exercise is associated with lower total WBC, neutrophil, and monocyte counts. However, no studies have evaluated the effect of the amount of aerobic exercise (dose on total WBC and WBC subfraction counts. PURPOSE: To examine the effects of 3 different doses of aerobic exercise on changes in total WBC and WBC subfraction counts and independent effects of changes in fitness, adiposity, markers of inflammation (IL-6, TNF-α, C-reactive protein, fasting glucose metabolism, and adiponectin. METHODS: Data from 390 sedentary, overweight/obese postmenopausal women from the DREW study were used in these analyses. Women were randomized to a non-exercise control group or one of 3 exercise groups: energy expenditure of 4, 8, or 12 kcal kg(-1⋅week(-1 (KKW for 6 months at an intensity of 50% VO2peak. RESULTS: A dose-dependent decrease in total WBC counts (trend P = 0.002 was observed with a significant decrease in the 12KKW group (-163.1±140.0 cells/µL; mean±95%CI compared with the control (138.6±144.7 cells/µL. A similar response was seen in the neutrophil subfraction (trend P = 0.001 with a significant decrease in the 12KKW group (-152.6±115.1 cells/µL compared with both the control and 4KKW groups (96.4±119.0 and 21.9±95.3 cells/µL, respectively and in the 8KKW group (-102.4±125.0 cells/µL compared with the control. When divided into high/low baseline WBC categories (median split, a dose-dependent decrease in both total WBCs (P = 0.003 and neutrophils (P<0.001 was observed in women with high baseline WBC counts. The effects of exercise dose on total WBC and neutrophil counts persisted after accounting for significant independent effects of change in waist circumference and IL-6. CONCLUSION: Aerobic exercise training reduces total WBC and neutrophil counts, in a dose-dependent manner, in

    During the period November 1994 - May 1995 the coordinating group of WBC centres working in Italy organised the 2. national intercalibration and intercomparison campaign. A BOMAB phantom was used filled with four radionuclides gel solution with gamma energy emissions ranging between 100 keV and 2 MeV. 17 out of 21 Italian WBC centres took part in the campaign. Through the intercalibration, organised according to internationally accepted methodologies, each WBC centre could check its own calibration procedures. many intermediate data, collected for the methodologies and measurement procedures intercomparison, permitted analyses and comparison of uncertainly causes in a WBC measurement of the internal contamination. A proposal of MDA definition and assessment procedure resulted from the intercomparison campaign. [Italiano] Il Coordinamento dei Centri WBC operanti in Italia ha organizzato la seconda campagna di intercalibrazione ed interconfronto nazionale basata sulle misure di un fantoccio BOMAB riempito con una soluzione radioattiva gelificata contenente 4 radionuclidi con emissioni gamma nell`intervallo energetico compreso fra 100 keV e 2 MeV. Alla campagna, che si e` svolta fra novembre 1994 e maggio 1995, hanno partecipato 17 dei 21 Centri WBC censiti in Italia. L`intercalibrazione e` stata organizzata secondo criteri ormai consolidati in campo internazionale ed ha permesso ad ognuno dei partecipanti di verificare le proprie procedure di calibrazione. Per l`interconfronto delle procedure e dei metodi di misura impiegati e` stata raccolta una serie di dati intermedi che hanno consentito di analizzare e confrontare le fonti di incertezza insite nella misura di contaminazione interna nell`uomo tramite WBC. Cio` ha infine reso possibile una proposta di definizione e di procedura di determinazione del valore della minima attivita` rivelabile (MDA) in accordo con le piu` recenti tendenze in campo internazionale.

  17. 99Tcm stannous WBC study in childhood inflammatory bowel disease- what benefit?

    International Nuclear Information System (INIS)

    Full text: Inflammatory bowel disease (IBD) is increasingly recognised in the paediatric population. Management requires early diagnosis with determination of disease localisation and intensity. The 99Tcm labelled white blood cell (WBC) study has been used for IBD in adults but little data is available in children. The most common agent used is 99Tcm HMPAO however, this is time consuming and expensive. The use of 99Tcm sulphur colloid labelled WBC is an easy, reliable technique. 70 patients aged 2-19 years (mean 12.7) were studied. Planar and SPECT imaging was performed at one and three hours. 38 patients with proven IBD had positive WBC. Of 32 with negative WBC, five had IBD, however, three were on treatment with steroids. 18 patients had barium radiography (BR): nine (50%) were positive for IBD whereas 18 (100%) were positive on WBC. Comparison with endoscopy showed good correlation of areas involved in 45%, 18% had different areas and 36% had more areas defined on endoscopy. In the latter group 14% had positive endoscopy in the stomach and duodenum, which are area not visualised on WBC studies. The WBC has a sensitivity of 95%, specificity of 100% and accuracy of 93%. For BR the sensitivity was 53%, specificity 100% and accuracy 63%. Conclusion: WBC is a good screening investigation for IBD prior to having other invasive investigations. This study would suggest that the barium radiographic study does not offer additional benefits over the WBC and endoscopy in determining the initial diagnosis and extent of the disease.

  1. Additive value of three-phase of Tc-99m HMPAO WBC scintigraphy in patients with suspected knee prosthesis infection

    International Nuclear Information System (INIS)

    We investigated if three-phase Tc-99m HMPAO WBC scintigraphy (TP-WBC) to detect infection in patients with knee protheses has more additive values than conventional Tc-99m HMPAO WBC scintigraphy (C-WBC). Thirty patients (M: F=8: 22, Age; 69.26.2 yrs) with suspected knee prothesis infection were enrolled in our study. We performed Tc-99m HMPAO WBC scintigraphies at 4 different time points after the injection of the labeled leukocytes; Immediately after the bolus injection (perfusion phase image), 1 min (blood-pool phase image), and 1 and 3 hours (delayed static images, C-WBC). The final diagnosis of infection was based on surgical, histologic, and bacteriologic data and other follow-up studies. We compared with diagnostic performance between TP-WBC and C-WBC. Twenty patients (66.7%) finally had infected prothesis, the other ten (33.3%) didn't have it. C-WBC showed 85.0% of sensitivity, 30.0% of specificity, 70.8% of PPV, 50.0% of PNV, and 66.7% of accuracy. TP-WBC also showed 95.0% of sensitivity, 30.0% of specificity, 73.1 % of PPV, 75.0% of PNV, and 73.3% of accuracy. TP-WBC demonstrated higher sensitivity and accuracy than C-WBC. Three-phase images of Tc-99m HMPAO WBC scintigraphy may have more additive value to detect infection in patients with suspected knee prosthesis infection

    Pseudomonas sp. Strain WBC-3 utilized methyl parathion or para-nitrophenol (PNP) as the sole source of carbon, nitrogen, andenergy, and methyl parathion hydrolase had been previously characterized. Its chemotactic behaviors to aromatics were investigated.The results indicated that strain WBC-3 was attracted to multiple aromatic compounds, including metabolizable or transformablesubstrates PNP, 4-nitrocatehol, and hydroquinone. Disruption of PNP catabolic genes had no effect on its chemotactic behaviors with the same substrates, indicating that the chemotactic response in this swain was metabolism-independent. Furthermore, it was shownthat strain WBC-3 had a constitutive β-ketoadipate chemotaxis system that responded to a broad range of aromatic compounds, whichwas different from the inducible β-ketoadipate chemotaxis described in other Pseudomonas signs.

    In flowering plants, the exine components are derived from tapetum. Despite its importance to sexual plant reproduction, little is known about the translocation of exine materials from tapetum to developing microspores. Here we report functional characterization of the arabidopsis WBC27 gene. WBC27 encodes an adenosine tri-phosphate binding cassette (ABC) transporter and is expressed preferentially in tapetum. Mutation of WBC27 disrupted the exine formation. The wbc27 mutant microspores began to degenerate once released from tetrads and most of the microspores collapsed at the uninucleate stage. Only a small number of wbc27-1 microspores could develop into tricellular pollen grains. These survival pollen grains lacked exine and germinated in the anther before anthesis. All of these results suggest that the ABC transporter, WBC27 plays important roles in the formation of arabidopsis exine, possibly by translocation of lipidic precursors of sporopollenin from tapetum to developing microspores.

    Objective: The purpose of this study was to determine whether the decrease of WBC is correlated with the increase of apoptosis induced by cytotoxic drugs in patients who received neoadjuvant polychemotherapy for ovarian cancer and whether the reduction of peripheral blood WBC can be predicted by the detection of apoptosis. Methods: The study included 25 patients who received neoadjuvant polychemotherapy for ovarian cancer after operation. Total 2 ml of venous blood was collected from these subjects within 24 hours before chemotherapy and at the fifth day after the beginning of chemotherapy. Peripheral blood WBC count was performed and its apoptosis was analyzed using flow cytometry (FCM) and DNA electrophoresis. Results: 68% (17/25) of the patients had a decrease in WBC after chemotherapy. The average counts of WBC were 5.19±1.36×109/L and 4.36±1.56×109/L, the distributions were 4.10~8.60×109/L and 2.00~7.90×109/L before and after chemotherapy respectively. At the same time, 64%(16/25) of the patients had an increase in apoptotic cells. The proportions of apoptosis were 4.01±2.59% and 5.66±1.36%, the distributions were 1.05~11.02% and 0.8~14.08% before and after chemotherapy respectively. Both the decrease of WBC and the increase of apoptosis were statistical significant (P<0.05). The coefficient between the decrease of WBC and the increase of apoptosis is 0.646(P<0.05). The sensitivity of the quantitative analysis of apoptosis using FCM for clinical early diagnosis of the decrease of WBC is 82%, the speciality is 75% and the accuracy is 80%. Conclusion: The increased apoptosis induced by cytotoxic drugs contributed to the chemotherapy-associated reduction of WBC at some extend, there were somewhat correlation between them. The detection of peripheral apoptosis could be of some help to assess the decrease and scientific bases for the administration of G-CSF, GM-CSF to obtain the optimal cost-effectiveness of clinical chemotherapy.

    In-111 WBC scintigraphy in a women with relapsed acute lymphoid leukemia demonstrated normal uptake of white blood cells by the liver and spleen, but virtually absent bone marrow activity. Tc-99m Sc imaging confirmed normal marrow function and distribution. A bone marrow biopsy revealed mildly hypocellular, regenerating marrow without leukemic infiltration. The effects of systemic cytotoxic chemotherapy on marrow reticuloendothelial function may have been responsible for this discordant uptake. 5 refs., 2 figs.

    Full Text Available Perinatal asphyxia is a major cause of neonatal mortality and chronic neurologic disability amongst survivors. There is no single parameter to define perinatal asphyxia. Recent studies have established a correlation between cord blood nucleated red blood cell count and severity of perinatal asphyxia. AIMS AND OBJECTIVES To evaluate the utility of cord blood nucleated red blood cell/100 WBC count in early identification of perinatal asphyxia and in predicting its severity. MATERIALS AND METHOD This is a case-control study with a total number of 100 subjects, out of which 50 are asphyxiated/case group and the other 50 are non-asphyxiated/control group, which include neonates born in Gandhi Hospital in the Department of Obstetrics and Gynecology. Immediately after birth, umbilical cord blood is collected and a thin blood smear slide is prepared which is stained with Leishman stain for NRBC count. The NRBC count of the case group and the control group is compared. The results were analyzed statistically. RESULTS The mean NRBC count in case group was 38.3 and that in control group was 5.24 with significant rise in cord blood NRBC/100 WBC count in case group compared to controlled group with p value <0.001. Increase in NRBC/100 WBC count was also associated with increased severity of HIE in case group. CONCLUSION In conditions where blood gas analyzers are not easily available, cord blood NRBC count can be used as a cheaper and reliable alternative to predict perinatal asphyxia and to assess its severity.

    The Dehalogenimonas population in a dechlorinating enrichment culture referred to as WBC-2 was previously shown to be responsible for trans-dichloroethene (tDCE) hydrogenolysis to vinyl chloride (VC). In this study, blue native polyacrylamide gel electrophoresis (BN-PAGE) followed by enzymatic assays and protein identification using liquid chromatography coupled with mass spectrometry (LC-MS/MS) led to the functional characterization of a novel dehalogenase, TdrA. This new reductive dehalogenase (RDase) catalyzes the dechlorination of tDCE to VC. A metagenome of the WBC-2 culture was sequenced, and a complete Dehalogenimonas genome, only the second Dehalogenimonas genome to become publicly available, was closed. The tdrA dehalogenase found within the Dehalogenimonas genome appears to be on a genomic island similar to genomic islands found in Dehalococcoides. TdrA itself is most similar to TceA from Dehalococcoides sp. strain FL2 with 76.4% amino acid pairwise identity. It is likely that the horizontal transfer of rdhA genes is not only a feature of Dehalococcoides but also a feature of other Dehalococcoidia, including Dehalogenimonas. A set of primers was developed to track tdrA in WBC-2 subcultures maintained on different electron acceptors. This newest dehalogenase is an addition to the short list of functionally defined RDases sharing the usual characteristic motifs (including an AB operon, a TAT export sequence, two iron-sulfur clusters, and a corrinoid binding domain), substrate flexibility, and evidence for horizontal gene transfer within the Dehalococcoidia.

  12. Detection of occult infection following total joint arthroplasty using sequential technetium-99m HDP bone scintigraphy and indium-111 WBC imaging

    International Nuclear Information System (INIS)

    Preoperative exclusion or confirmation of periprosthetic infection is essential for correct surgical management of patients with suspected infected joint prostheses. The sensitivity and specificity of [111In]WBC imaging in the diagnosis of infected total joint prostheses was examined in 28 patients and compared with sequential [/sup 99m/Tc]HDP/[111In]WBC scintigraphy and aspiration arthrography. The sensitivity of preoperative aspiration cultures was 12%, with a specificity of 81% and an accuracy of 58%. The sensitivity of [111In]WBC imaging alone was 100%, with a specificity of 50% and an accuracy of 65%. When correlated with the bone scintigraphy and read as sequential [/sup 99m/Tc]HDP/[111In]WBC imaging, the sensitivity was 88%, specificity 95%, and accuracy 93%. This study demonstrates that [111In]WBC imaging is an extremely sensitive imaging modality for the detection of occult infection of joint prostheses. It also demonstrates the necessity of correlating [111In]WBC images with [/sup 99m/Tc]HDP skeletal scintigraphy in the detection of occult periprosthetic infection

    Pseudomonas sp. strain WBC-3 utilizes para-nitrophenol (PNP) as a sole carbon and energy source. The genes involved in PNP degradation are organized in the following three operons: pnpA, pnpB, and pnpCDEFG. How the expression of the genes is regulated is unknown. In this study, an LysR-type transcriptional regulator (LTTR) is identified to activate the expression of the genes in response to the specific inducer PNP. While the LTTR coding gene pnpR was found to be not physically linked to any of the three catabolic operons, it was shown to be essential for the growth of strain WBC-3 on PNP. Furthermore, PnpR positively regulated its own expression, which is different from the function of classical LTTRs. A regulatory binding site (RBS) with a 17-bp imperfect palindromic sequence (GTT-N11-AAC) was identified in all pnpA, pnpB, pnpC, and pnpR promoters. Through electrophoretic mobility shift assays and mutagenic analyses, this motif was proven to be necessary for PnpR binding. This consensus motif is centered at positions approximately -55 bp relative to the four transcriptional start sites (TSSs). RBS integrity was required for both high-affinity PnpR binding and transcriptional activation of pnpA, pnpB, and pnpR. However, this integrity was essential only for high-affinity PnpR binding to the promoter of pnpCDEFG and not for its activation. Intriguingly, unlike other LTTRs studied, no changes in lengths of the PnpR binding regions of the pnpA and pnpB promoters were observed after the addition of the inducer PNP in DNase I footprinting.

    The Plan of Radiological Protection licensed by the National Nuclear Energy Commission - CNEN in Brazil includes the risks of assessment of internal and external exposure by implementing a program of individual monitoring which is responsible of controlling exposures and ensuring the maintenance of radiation safety. The Laboratory of Internal Dosimetry of the Center for Development of Nuclear Technology - LID/CDTN is responsible for routine monitoring of internal contamination of the Individuals Occupationally Exposed (IOEs). These are, the IOEs involved in handling {sup 18}F produced by the Unit for Research and Production of Radiopharmaceuticals sources; as well a monitoring of the entire body of workers from the Research Reactor TRIGA IPR-R1/CDTN or whenever there is any risk of accidental incorporation. The determination of photon emitting radionuclides from the human body requires calibration techniques of the counting geometries, in order to obtain a curve of efficiency. The calibration process normally makes use of physical phantoms containing certified activities of the radionuclides of interest. The objective of this project is the calibration of the WBC facility of the LID/CDTN using the BOMAB physical phantom and Monte Carlo simulations. Three steps were needed to complete the calibration process. First, the BOMAB was filled with a KCl solution and several measurements of the gamma ray energy (1.46 MeV) emitted by {sup 40}K were done. Second, simulations using MCNPX code were performed to calculate the counting efficiency (Ce) for the BOMAB model phantom and compared with the measurements Ce results. Third and last step, the modeled BOMAB phantom was used to calculate the Ce covering the energy range of interest. The results showed a good agreement and are within the expected ratio between the measured and simulated results. (Author)

  17. para-Nitrophenol 4-monooxygenase and hydroxyquinol 1,2-dioxygenase catalyze sequential transformation of 4-nitrocatechol in Pseudomonas sp. strain WBC-3.

    2010-11-01

    Pseudomonas sp. strain WBC-3 utilizes para-nitrophenol (PNP) as a sole source of carbon, nitrogen and energy. PnpA (PNP 4-monooxygenase) and PnpB (para-benzoquinone reductase) were shown to be involved in the initial steps of PNP catabolism via hydroquinone. We demonstrated here that PnpA also catalyzed monooxygenation of 4-nitrocatechol (4-NC) to hydroxyquinol, probably via hydroxyquinone. It was the first time that a single-component PNP monooxygenase has been shown to catalyze this conversion. PnpG encoded by a gene located in the PNP degradation cluster was purified as a His-tagged protein and identified as a hydroxyquinol dioxygenase catalyzing a ring-cleavage reaction of hydroxyquinol. Although all the genes necessary for 4-NC metabolism seemed to be present in the PNP degradation cluster in strain WBC-3, it was unable to grow on 4-NC as a sole source of carbon, nitrogen and energy. This was apparently due to the substrate's inability to trigger the expression of genes involved in degradation. Nevertheless, strain WBC-3 could completely degrade both PNP and 4-NC when PNP was used as the inducer, demonstrating its potential in bioremediation of the environment polluted by both 4-NC and PNP.

  19. Precise fusion of MRI and dual energy 111In WBC/99mTc HDP SPECT/CT in the diabetic foot using companion CT: an example of SPECT/MRI imaging

    International Nuclear Information System (INIS)

    The purpose of our study was to correctly fuse MRI and SPECT 111In WBC and 99m Tc HDP images using companion CT images. The fused images could be used to assess proper surgical approach in treatment of the diabetic foot. Nine patients who had dual energy 111In WBC/ 99m Tc HDP SPECT/CT and MRI studies within a week were investigated in an ongoing project. A GE Infinia SPECT/CT camera and Siemens MAGNETOM 1.5T MR system were used in this study. First, the MRI and corresponding CT images were coregistrated using a transformation based on normalized mutual information. The transformation was saved and used for MRI and 111In WBC/ 99m Tc HDP SPECT fusion. A Jaszczak phantom study was also performed in order to estimate accuracy of MRI/ SPECT fusion. The Jaszczak phantom study with 3.7 MBq 111In hot sphere showed that MRI/SPECT alignment using the approach described above produced registration with 0.7±0.4 mm accuracy in all three dimensions (3D). The nine clinical cases were visually evaluated and showed 1-2 mm 3D fusion accuracy. MRI provides almost perfect anatomy of soft tissue and bony structures but it may exaggerate the extent of infection. 111In WBC/99m Tc HDP SPECT imaging is more accurate for infection detection but lacks anatomical reference. Combination of these images proved an essential adjunct to diagnosis. A clinical utility of the approach is illustrated in two clinical examples. In conclusion, the CT in dual energy 111In WBC/99m Tc HDP SPECT/CT studies can be used to accurately fuse and compare 111In WBC/99m Tc HDP SPECT and MRI images of the diabetic foot. This can significantly help in conservative treatment planning and limb salvage procedures in treatment of diabetic foot infections.

  10. Applicability test of methods for discrimination between external and internal contamination using an ORTEC whole body counter

    International Nuclear Information System (INIS)

    Whole-body counters (WBCs) are generally used for monitoring internal radioactive contamination of radiation workers in nuclear power plants. However, it has been found that external contamination is occasionally counted as internal contamination. The previous study was conducted to provide guidance on measuring the exact internal radioactivity using a Canberra WBC. However, there is strong need to verify the application of the previous study to whole-body counting using a different type of WBC, ORTEC StandFAST II. Thus, in this study, several experiments were conducted focusing on the discrimination between external and internal contamination. Finally, it was found that counts from the front and back are still effective to distinguish external contamination from internal contamination for whole-body counting. (authors)

    Full Text Available The study investigated the effects of chronic alcohol use on HIV viral load in HIV-infected patients on d4T/3TC/NVP drug regimen during 9 months follow up period. It also determined plasma drug concentrations of d4T, 3TC and NVP; CD4+ and WBC counts for patients with high HIV viral load. A case-control study using repeated measures with serial measurements was used. A total of 41 patients (20 alcohol group and 21 control group were screened for alcohol use using WHO AUDIT tool and chronic alcohol use biomarkers. Blood sampling was done at 3 month intervals for a period of 9 months. HIV viral load was determined using Roche Amplicor HIV-1 monitor test, version 1.5 (Amplicor. The d4T, 3TC and NVP concentrations were determined by Shimadzu Class-VPTM HPLC Chromatography data system version 6.1. The CD4+ cell count was determined using FACSCalibur flow cytometer. The WBC was determined using automated hematological Coulter CBC-5 Hematology Analyzer system. Results show that % patients with HIV viral load ≥400 copies/ml in control group was highest (23.8%, n=5 at 3 month while in chronic alcohol use group, it was at 0 month (35%, n=7 for both WHO AUDIT tool and chronic alcohol-use biomarkers groups. Generally patients with high viral load ≥400 copies/ml was observed in chronic alcohol use as compared to control group in both WHO AUDIT tool and biomarkers group despite of patients having high steady state d4T, 3TC and NVP plasma drug concentrations in circulation that is available to suppress HIV virus. The high viral load could be associated with the emergence of resistance of the HIV virus and these patients generally had a low CD4+ cell count. Some of these patients had no detectable d4T plasma drug concentrations in circulation and most of them with high viral load had sub-therapeutic NVP plasma drug concentrations in their blood circulation. Chronic ethanol use by HIV-infected patients on d4T/3TC/NVP drug regimen increased HIV viral load and

  1. Performance optimisation through EPT-WBC in mobile ad hoc networks

    Science.gov (United States)

    Agarwal, Ratish; Gupta, Roopam; Motwani, Mahesh

    2016-03-01

    Mobile ad hoc networks are self-organised, infrastructure-less networks in which each mobile host works as a router to provide connectivity within the network. Nodes out of reach to each other can communicate with the help of intermediate routers (nodes). Routing protocols are the rules which determine the way in which these routing activities are to be performed. In cluster-based architecture, some selected nodes (clusterheads) are identified to bear the extra burden of network activities like routing. Selection of clusterheads is a critical issue which significantly affects the performance of the network. This paper proposes an enhanced performance and trusted weight-based clustering approach in which a number of performance factors such as trust, load balancing, energy consumption, mobility and battery power are considered for the selection of clusterheads. Moreover, the performance of the proposed scheme is compared with other existing approaches to demonstrate the effectiveness of the work.

    Full Text Available Abstract Background Results from increasing numbers of in vitro and in vivo studies have demonstrated that omega 3 fatty acids incorporated in cell culture media or in the diet of the animals can suppress the growth of cancers. When human clinical trials are initiated to determine the ability of omega 3 fatty acids to alter growth or response to chemotherapeutic interventions of cancers, it will be essential to determine the omega 3 intake of individuals in the trial to determine compliance with consumption of the supplement and to correlate with endpoints of efficacy. We wondered if the fatty acid composition of RBCs might accurately indicate incorporation of omega 3 fatty acids in the WBCs. In this report we determine and compare the changes in fatty acid compositions of red blood cells and white blood cells in response to consumption of three doses of an omega 3 fatty acid supplement. Results We found that the fraction of omega 3 fatty acids in both red blood cells and white blood cells increased following consumption of the supplement. There was a linear, dose responsive increase in the fraction of omega 3 fatty acids in red blood cells but the increase in omega 3 in white blood cells was not linear. The magnitude of increase in omega 3 fatty acids was different between the two cell types. Conclusions Fatty acid analysis of red blood cells is a good measure of compliance with supplement consumption. However, fatty acid analysis of white blood cells is needed to correlate changes in fatty acid composition of white blood cells with other biochemical changes in the white blood cells.

  4. Sensitivity of a low energy Ge detector system for in vivo monitoring in the framework of ICRP 78 applications

    International Nuclear Information System (INIS)

    In in vivo detection of internal contamination by actinides the minimum detectable activities (MDAs) correspond to significant doses, so the sensitivity of the detection system is the key to establishing adequate individual monitoring programmes for internal exposures of these radionuclides. The whole body counting (WBC) faculty at CIEMAT uses a low-energy Ge detector system with different available counting geometries to estimate the retention of actinides in the lungs and evaluate 125I in thyroid and 241Am in bone (skull and knee). A study of the factors and uncertainties involved in estimations of MDA is presented for lung and thyroid monitoring. The dependence of detection limits on counting efficiency in the measurement of low-energy emitters in lungs has been carefully studied, carrying out a comparison among different biometric equations obtained by ultrasound techniques for estimations of chest wall thickness. Dosimetric implications of the estimated MDS's are taken into account in the framework of ICRP-78 application and considering Spanish regulations. The main interest in lung measurements is for the assessment of occupational exposures. This work confirms the low-energy Ge detector system as an adequate in vivo technique for the routine monitoring of internal exposure to most insoluble uranium compounds (detection of 3% enriched uranium in lungs), and also to be useful in special monitoring programmes or in case of incidents when the detection of 241Am is required.

    Aerogel materials possess a wide variety of exceptional properties, hence a striking number of applications have developed for them. Many of the commercial applications of aerogels such as catalysts, thermal insulation, windows, and particle detectors are under development and new applications have been publicized since the ISA4 Conference in 1994: e.g., supercapacitors, insulation for heat storage in automobiles, electrodes for capacitive deionization, etc. More applications are evolving as the scientific and engineering community becomes familiar with the unusual and exceptional physical properties of aerogels. In addition to growing commercial applications of aerogels, there are also scientific and technical applications, as well. This paper discusses a variety of technical applications of aerogels. It reports current technical applications under development for which several types of aerogels are formed in custom sizes and shapes

    International Nuclear Information System (INIS)

    PRIBIC plant (Pollutants Reduction In small Biomass Combustion systems) at CEDER is a facility specifically designed to do biomass combustion tests. In these tests is necessary to know the values of different sensors in real time. With this information the PRIBIC plant is regulated to its optimum point of work and its possible to follow the operation criteria and get test objectives. Different electronic instruments record information about the plant operation. A software application was developed to let a centralised motorization of that information. The application communicates with the instrumentation, recovers data, lets operators see data in real time and saves the information in files. An important part of this document describes that application, and some considerations to generalise this kind of developments to other Experimental Plants, including cost estimations. Descriptions of plant, analysis of the problem, result evaluations, and conclusions can also be found in the document. (Author) 13 refs

    In re-listening to the lectures of Charles Townes shortly after the invention of the laser (e.g., in the Boston Science Museum), one can already have a realistic vision of the potentialities of this new tool in the field of medical therapy, as evidenced by the use of the laser in ophthalmology to cure retinal detachment in the 1960's. Since then, applications have flourished in the domain of therapy. We will thus illustrate here only some of the main fields of application of medical lasers. On the opposite, the use of lasers in medical imaging is, with one exception in ophthalmology, still at the development level. It is becoming a diagnostic tool in addition to high performance imaging facilities that are often very expensive (such as CT scan, Magnetic Resonance Imaging (MRI) and nuclear imaging). Even if progress is sometimes slow, one can now image with light inside the human body, in spite of the strong scattering of light by tissues, in the same way as a pathologist sees surgical specimens.

    The work discusses the main clinical features of inflammatory bowel disease (IBD) and the methods to obtain an accurate diagnostic. Nuclear medicine procedures are deeply analysed, with special emphasis in those where clinical experience is larger and that are available for clinical practice in most countries. In the opinion of the authors [sup 99m]Tc-HMPAO is the first choice agent, while [sup 111]In-oxine could be considered as a gold standard for evaluation of new agents. In the context of IBD, the WBC scintigraphy is useful for its diagnosis and the evaluation of disease extension. The evaluation of disease severity deserves further experiences.

    Lower urinary tract symptoms can indicate the presence of urinary tract infection (UTI), a condition that if it becomes chronic requires expensive and time consuming care as well as leading to reduced quality of life. Detecting the presence and gravity of an infection from the earliest symptoms is then highly valuable. Typically, white blood cell (WBC) count measured in a sample of urine is used to assess UTI. We consider clinical data from 1341 patients in their first visit in which UTI (i.e. WBC ≥ 1) is diagnosed. In addition, for each patient, a clinical profile of 34 symptoms was recorded. In this paper, we propose a Bayesian nonparametric regression model based on the Dirichlet process prior aimed at providing the clinicians with a meaningful clustering of the patients based on both the WBC (response variable) and possible patterns within the symptoms profiles (covariates). This is achieved by assuming a probability model for the symptoms as well as for the response variable. To identify the symptoms most associated to UTI, we specify a spike and slab base measure for the regression coefficients: this induces dependence of symptoms selection on cluster assignment. Posterior inference is performed through Markov Chain Monte Carlo methods. PMID:26536840

    Fusion has a wide spectrum of applications that appear technically possible and may become economically feasible. Near-term (approx. 2000) application for production of nuclear fuels and useful radioisotopes is an economically attractive possibility as soon as fusion is ready. Electricity production will remain a prime, large-scale application of fusion. In the longer term, as fossil fuels dwindle, production of hydrogen could become a major application. Additional applications some of which have not even been conceived of yet, will add to this potential richness and diversity of fusion. It is the purpose of the fusion applications study - FMAE - to innovate, investigate, and evaluate these potential applications.

    Ruby on Rails is an open source web application framework for the Ruby programming language. The first application I built was a web application to manage and authenticate other applications. One of the main requirements for this application was a single sign-on service. This allowed authentication to be built in one location and be implemented in many different applications. For example, users would be able to login using their existing credentials, and be able to access other NASA applications without authenticating again. The second application I worked on was an internal qualification plan app. Previously, the viewing of employee qualifications was managed through Excel spread sheets. I built a database driven application to streamline the process of managing qualifications. Employees would be able to login securely to view, edit and update their personal qualifications.

    Full Text Available Due to the superior ability of photocatalysis to inactivate a wide range of harmful microorganisms, it is being examined as a viable alternative to traditional disinfection methods such as chlorination, which can produce harmful byproducts. Photocatalysis is a versatile and effective process that can be adapted for use in many applications for disinfection in both air and water matrices. Additionally, photocatalytic surfaces are being developed and tested for use in the context of “self-disinfecting” materials. Studies on the photocatalytic technique for disinfection demonstrate this process to have potential for widespread applications in indoor air and environmental health, biological, and medical applications, laboratory and hospital applications, pharmaceutical and food industry, plant protection applications, wastewater and effluents treatment, and drinking water disinfection. Studies on photocatalytic disinfection using a variety of techniques and test organisms are reviewed, with an emphasis on the end-use application of developed technologies and methods.

    My project at KSC during my spring 2011 internship was to develop a Ruby on Rails application to manage Content Documents..A Content Document is a collection of documents and information that describes what software is installed on a Launch Control System Computer. It's important for us to make sure the tools we use everyday are secure, up-to-date, and properly licensed. Previously, keeping track of the information was done by Excel and Word files between different personnel. The goal of the new application is to be able to manage and access the Content Documents through a single database backed web application. Our LCS team will benefit greatly with this app. Admin's will be able to login securely to keep track and update the software installed on each computer in a timely manner. We also included exportability such as attaching additional documents that can be downloaded from the web application. The finished application will ease the process of managing Content Documents while streamlining the procedure. Ruby on Rails is a very powerful programming language and I am grateful to have the opportunity to build this application.

  16. Applications of cavity optomechanics

    Science.gov (United States)

    Metcalfe, Michael

    2014-09-01

    "Cavity-optomechanics" aims to study the quantum properties of mechanical systems. A common strategy implemented in order to achieve this goal couples a high finesse photonic cavity to a high quality factor mechanical resonator. Then, using feedback forces such as radiation pressure, one can cool the mechanical mode of interest into the quantum ground state and create non-classical states of mechanical motion. On the path towards achieving these goals, many near-term applications of this field have emerged. After briefly introducing optomechanical systems and describing the current state-of-the-art experimental results, this article summarizes some of the more exciting practical applications such as ultra-sensitive, high bandwidth accelerometers and force sensors, low phase noise x-band integrated microwave oscillators and optical signal processing such as optical delay-lines, wavelength converters, and tunable optical filters. In this rapidly evolving field, new applications are emerging at a fast pace, but this article concentrates on the aforementioned lab-based applications as these are the most promising avenues for near-term real-world applications. New basic science applications are also becoming apparent such as the generation of squeezed light, testing gravitational theories and for providing a link between disparate quantum systems.

    Full Text Available Carbon nanotubes (CNTs are a fascinating subject for curiosity-driven research. But will they give rise to commercially viable applications? CNTs are rolled up sheets of sp2; bonded graphite with no surface broken bonds. Their possible applications1,2; arise from the remarkable properties of single-walled nanotubes (SWNTs such as the highest Young's modulus, highest thermal conductivity, ballistic electron transport, and high aspect ratio structure. To date, development of nanotube-based products has been delayed by a lack of availability of quantities of material and lack of control of their growth. Supplies of multi-walled nanotubes (MWNTs or nanofibers have been available from Hyperion Catalysis International, but under constraint and only as preformed composites. The supply situation is now improving with several firms producing on a larger scale, such as CNI, Showa Denko, Thomas Swan, and Nanocyl. Now is, therefore, a good time to look at applications from a more business view.

    2007-01-03

    Nucleic acid aptamers have found steadily increased utility and application steadily over the last decade. In particular, aptamers have been touted as a valuable complement to and in some cases replacement for antibodies due to their structural and functional robustness as well as their ease in generation and synthesis. They are thus attractive for biosecurity applications, e.g. pathogen detection, and are especially well suited since their in vitro generation process does not require infection of any host systems. Herein we provide a brief overview of the aptamers generated against biopathogens over the last few years. In addition, a few recently described detection platforms using aptamers (aptasensors) and potentially suitable for biosecurity applications will be discussed.

    2006-01-01

    Compton scattering is used very widely. In this article, we depict an overall picture for its applications which are based on two basic theories. The first is the electron densitometry theory related to electron density. According to this theory its applications are in two fields: one is Compton scatter densitometry (CSD), the other is Compton scatter imaging (CSI). The second technique involves the electron momentum distribution and Compton profile. Applications of this technique are mainly the Compton profile analysis (CPA) and the Compton profile or the electron momentum distribution in physics and chemistry.Future research fields are suggested according to the current situation and limits of this technique and a promising prospect is unfolded.

    Full Text Available The objective of the present study was to evaluate the application of some strip test markers (i.e., leukocyte esterase (LE activity, protein, nitrate and pH for diagnosis of endometritis in dairy cows using vaginal fornix discharge. Also, the total white blood cell count (t-WBC/l of this secretion and degenerative changes of neutrophils in cervical cytology were used as alternative methods to predict progression of the endometritis severity. Holstein cows (n=215 between 30-40 days in milk (DIM were included and examined. Giemsa-stained smear was prepared from cervical mucus. Cervical cytology test was considered as reference screening method for the detection of subclinical endometritis. The LE activity and t-WBC in the vaginal fornix discharge of subclinical endometritis cows were significantly higher than those from healthy cows. Sensitivity and specificity were 78% and 73% for LE10 activity (10 minutes after contacting with discharges and 60% and 69% for t-WBC (cut off point=210 cells/l for diagnosis of subclinical endometritis, respectively. There was a good agreement between LE10 activity, t-WBC and cervical cytology test with a Kappa coefficient of 0.4 and 0.42, respectively (P<0.0001. Total WBC count in discharge and degenerative neutrophils (DN percentages increase simultaneously with the degree and severity of endometritis. There was a highly significant (P<0.01 correlation between t-WBC and some reagent strip test markers (LE activity, protein and nitrate in clear discharge of studied cows. In conclusion, the present results suggest the LE activity and t-WBC in vaginal fornix discharge could be used as non-invasive reliable and valid methods for screening of subclinical endometritis in postpartum dairy herds.

    The Atmospheric Infrared Sounder (AIRS) on NASA's Aqua spacecraft has been returning daily global observations of Earth's atmospheric constituents and properties since 2002. With a 12-year data record and daily, global observations in near real-time, AIRS data can play a role in applications that fall under many of the NASA Applied Sciences focus areas. For vector-borne disease, research is underway using AIRS near surface retrievals to assess outbreak risk, mosquito incubation periods and epidemic potential for dengue fever, malaria, and West Nile virus. For drought applications, AIRS temperature and humidity data are being used in the development of new drought indicators and improvement in the understanding of drought development. For volcanic hazards, new algorithms using AIRS data are in development to improve the reporting of sulfur dioxide concentration, the burden and height of volcanic ash and dust, all of which pose a safety threat to aircraft. In addition, anomaly maps of many of AIRS standard products are being produced to help highlight "hot spots" and illustrate trends. To distribute it's applications imagery, AIRS is leveraging existing NASA data frameworks and organizations to facilitate archiving, distribution and participation in the BEDI. This poster will communicate the status of the applications effort for the AIRS Project and provide examples of new maps designed to best communicate the AIRS data.

    1997-02-01

    The article entitled "Novel Biocatalysts Will Work Even Better for Industry" published recently in this Journal (1) was informative and interesting. However it touched only briefly on the application of peroxidase as catalyst. Here, we would like to mention in more detail the novel applications of peroxidase in agricultural, paper pulp, water treatment, pharmaceutical, and medical situations. Firstly, the peroxidase isolated from Phanerochaete chyrosporium has been shown to detoxify herbicides such as atrazine to less toxic compounds and would certainly find potential application in agriculture (2). Secondly, the peroxidase produced by Streptomyces thermoviolaceus may find application in the paper pulp industry as a delignifying agent (3). Thirdly, it has been shown that extracellular peroxidase produced by Streptomyces avermitilis can remove the intense color from paper-mill effluent obtained after semichemical alkaline pulping of wheat straw (4), and thus this enzyme might find application as a catalyst in water treatment plants. Fourthly, the heme-containing horseradish peroxidase enzyme has been exploited in several diagnostic applications in pharmaceutics and medicine, such as the detection of human immunodeficiency virus and cystic fibrosis (5-10). Finally, recent work from our laboratory has suggested that thermophilic nonheme peroxidase produced by Thermomonospora fusca BD25 may find medical use in the diagnosis of myocardial infarction (11, 12).

    CERN Document Server

    Kaur, Inderjeet

    1983-01-01

    Two-dimensional materials created ab initio by the process of condensation of atoms, molecules, or ions, called thin films, have unique properties significantly different from the corresponding bulk materials as a result of their physical dimensions, geometry, nonequilibrium microstructure, and metallurgy. Further, these characteristic features of thin films can be drasti­ cally modified and tailored to obtain the desired and required physical characteristics. These features form the basis of development of a host of extraordinary active and passive thin film device applications in the last two decades. On the one extreme, these applications are in the submicron dimensions in such areas as very large scale integration (VLSI), Josephson junction quantum interference devices, magnetic bubbles, and integrated optics. On the other extreme, large-area thin films are being used as selective coatings for solar thermal conversion, solar cells for photovoltaic conver­ sion, and protection and passivating layers.

    International Nuclear Information System (INIS)

    The author discussed the issues concerning insulins of the different species (pig, dog and sperm whale) and the applications of species specific antisera in experimental and clinical settings. The possible role of a new form of ACTH as a hormonal marker was also discussed. Three species of insulin (pig, dog, and sperm whale) were separated by human antisera. Immune reaction was utilized to distinguish between endogenous human insulin and exogenously administered animal insulin. The longer acting insulins was found to be more immunogenic than regular crystalline insulins. Insulin concentrations in acid/ethanol extracts of the whole rat brain was about 25 times higher than plasma insulin. Plasma concentration of ACTH could be applicable to effect the distinction between tumor primary in or metastatic to the lung. (Nakanishi, T.)

    2014-06-01

    Full Text Available Most current strategies for bone regeneration have relatively satisfactory results. However, there are drawbacks and limitations associated with their use and availability, and even controversial reports about their efficacy and cost-effectiveness. The induction of new bone formation through distraction osteogenesis (DO is widespread clinical application in the treatment of bone defects, limb deformities, and fracture nonunions. However, a lengthy period of external fixation is usually needed to allow the new bone to consolidate, and complications such as refracture at the distraction gap often occur. Although various biomaterials have been used as injectable delivery systems in DO models, little has been reported on the use of nanobiomaterials as carrier materials for the sustained release of growth factors in bone regeneration. One area of focus in nanotechnology is the delivery of osteogenic factors in an attempt to modulate the formation of bone. This review article seeks to demonstrate the potential of nanobiomaterials to improve biological applications pertinent to osteodistraction.

    Tuchin, Valery V; Zimnyakov, Dmitry A

    2006-01-01

    Optical Polarization in Biomedical Applications introduces key developments in optical polarization methods for quantitative studies of tissues, while presenting the theory of polarization transfer in a random medium as a basis for the quantitative description of polarized light interaction with tissues. This theory uses the modified transfer equation for Stokes parameters and predicts the polarization structure of multiple scattered optical fields. The backscattering polarization matrices (Jones matrix and Mueller matrix) important for noninvasive medical diagnostic are introduced. The text also describes a number of diagnostic techniques such as CW polarization imaging and spectroscopy, polarization microscopy and cytometry. As a new tool for medical diagnosis, optical coherent polarization tomography is analyzed. The monograph also covers a range of biomedical applications, among them cataract and glaucoma diagnostics, glucose sensing, and the detection of bacteria.

  7. Numerical semigroups and applications

    CERN Document Server

    Assi, Abdallah

    2016-01-01

    This work presents applications of numerical semigroups in Algebraic Geometry, Number Theory, and Coding Theory. Background on numerical semigroups is presented in the first two chapters, which introduce basic notation and fundamental concepts and irreducible numerical semigroups. The focus is in particular on free semigroups, which are irreducible; semigroups associated with planar curves are of this kind. The authors also introduce semigroups associated with irreducible meromorphic series, and show how these are used in order to present the properties of planar curves. Invariants of non-unique factorizations for numerical semigroups are also studied. These invariants are computationally accessible in this setting, and thus this monograph can be used as an introduction to Factorization Theory. Since factorizations and divisibility are strongly connected, the authors show some applications to AG Codes in the final section. The book will be of value for undergraduate students (especially those at a higher leve...

  8. Clinical Applications for Estetrol

    Directory of Open Access Journals (Sweden)

    Visser M

    2010-01-01

    Full Text Available In this paper the potential clinical applications for the human fetal estrogen estetrol (E4 are presented based on recently obtained data in preclinical and clinical studies. In the past E4 has been classified as a weak estrogen due to its rather low estrogen receptor affinity. However, recent research has demonstrated that due to its favorable pharmacokinetic properties, especially the slow elimination and long half-life, E4 is an effective orally bioavailable estrogen agonist with estrogen antagonistic effects on the breast in the presence of estradiol. Based on the pharmacokinetic properties, the pharmacological profile and the safety and efficacy results in human studies, E4 seems potentially suitable as a drug for human use in applications such as hormone replacement therapy (vaginal atrophy and vasomotor symptoms, contraception, osteoporosis and breast cancer.

  9. Industrial applications at GANIL

    International Nuclear Information System (INIS)

    After a first round of industrial applications using heavy ion beams, GANIL has refocused these activities along the lines defined by a strategy and market study. Heavy ion industrial applications take their roots in the physical effects of the interactions occurring between heavy ion projectiles and matter. Specific equipments operated by GANIL or CIRIL allow users to take benefit from these effects. By heavy ion irradiation, industrial companies qualify radiation hardened electronic components and sensitize plastic films to produce 'nuclear track' membranes. Research and development programs with laboratories of the public sector, focus on heavy ion lithography dedicated to large area luminescent flat screens with field emitter microtips and on tribology with radioactive implanted ions. Even sometimes facing difficulties to fill the gap between industry and research, GANIL is eager to promote heavy ion beam technologies. (author) 36 refs., 6 figs., 5 tabs

  10. Triclosan: applications and safety.

    Science.gov (United States)

    Bhargava, H N; Leonard, P A

    1996-06-01

    Triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) is a nonionic, broad spectrum, antimicrobial agent that, because of its favorable safety profile, has been incorporated into a variety of many personal care products, including deodorant soaps, underarm deodorants, shower gels, and health care personnel handwashes. Triclosan exhibits a moderate degree of substantivity to the skin, and, in many products, it imparts a remnant antimicrobial effect. Although direct contact with the material under exaggerated exposure conditions causes dermal irritation in laboratory animals, it has only rarely been associated with skin irritation or sensitization in human being in formulated products. Acute, subacute/subchronic, and chronic toxicity profiles have been established to determine that triclosan is neither an acute oral toxicant nor that it acts as a carcinogen, mutagen, or teratogen. A new application for triclosan is in oral dentifrices for plaque control. Currently under investigation in the United States, it is approved for oral care application in Canada and many European countries.

    The graph is a critical and useful concept in designing many information processing systems. Systems such as transaction processing systems, decision support systems, and workflow systems are all helped immensely by a graphical structure. Simple graphs and digraphs allow for the construction of a variety of system design tools that provide a convenient and appealing format for illustrating information infrastructures, while allowing any subsequent analyses to be performed by the user. However, the metagraph, a new graphical structure that is developed in this book, goes beyond the representational and provides Information Systems with a robust, analytical modeling graphic tool. METAGRAPHS AND THEIR APPLICATIONS is a presentation of metagraph theory and its applications that begins by defining a metagraph and its uses. They are more complex than a simple graph structure, but they allow for representation and analysis of more complex systems. The material contained in this book is presented in two parts. The fi...

    As pointed out in the introduction of Part 1, the isolation strategy can be used to effectively decouple a structure from its environment and thus the structure can be protected from damaging seismic loads or unwanted vibrations and noises from the environment. The method has been used for solving vibration and shock problems in machinery and equipment for many years, but its application to the protection of structures from seismic loadings is relatively recent. Owing to the current interest generated by the Northridge and Kobe earthquakes, all but one of the papers in this publication deal with seismic isolation. The authors preview the papers in this section on the following applications of seismic isolation to: buildings, civil structures, industrial facilities, and nuclear plants.

  19. Overview of SMR applications

    International Nuclear Information System (INIS)

    Energy demand will continue to grow worldwide, with a faster growth in developing countries; consequently a wide range of options needs to be maintained for energy production and utilization in order to achieve environmental and economic objectives. This paper describes the various possibilities of non-electric applications of nuclear energy The temperature requirements for these applications vary greatly from low temperature heat for district heating and desalination to high temperature process heat for coal gasification and hydrogen production. Processes requiring temperatures of up to 300 deg. C can be supplied by water-cooled reactors while breeders may be applied to processes requiring up to 540 deg. C. The high temperature gas cooled reactor can provide process heat temperatures of 950 deg. C. Thus, nuclear energy has the potential to provide heat for many of the world's industrial heat application processes. Small and medium sized reactors are more suited for this purpose because of their reduced output capacity and grid size requirement. The attractiveness of using nuclear energy for non-electric applications, compared to fossil energy is the long-term stability of nuclear fuel prices in contrast to the rising prices of fossil fuels, increase of energy independence, decrease of the environmental impact and contribution to national technology and manpower development. The technical viability of employing nuclear heat sources for district heating or for industrial processes has existed since the very start of nuclear development. A substantial penetration into the commercial heat market, however, has not yet taken place. The prospects for the future will depend on where and how the demand characteristics of the heat market can be matched by what nuclear reactors are able to offer. (author)

    This report examines the market potential of a miniature, hand-held Ion Mobility Spectrometer. Military and civilian markets are discussed, as well as applications in a variety of diverse fields. The strengths and weaknesses of competing technologies are discussed. An extensive Ion Mobility Spectrometry (IMS) bibliography is included. The conclusions drawn from this study are: (1) There are a number of competing technologies that are capable of detecting explosives, drugs, biological, or chemical agents. The IMS system currently represents the best available compromise regarding sensitivity, specificity, and portability. (2) The military market is not as large as the commercial market, but the military services are more likely to invest R and D funds in the system. (3) Military applications should be addressed before commercial applications are addressed. (4) There is potentially a large commercial market for rugged, hand-held Ion Mobility Spectrometer systems. Commercial users typically do not invest R and D funds in this type of equipment rather, they wait for off-the-shelf availability.

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

Because of its advanced chapters and recent work, it is also appropriate for a more mature reader interested in recent applications and devel...

  4. Radioisotopes for medical applications

    International Nuclear Information System (INIS)

    For more than 3 decades, the Australian Nuclear Science and Technology Organisation has been the country's main supplier of radioisotopes for medical applications. The use of radioisotopes in medicine has revolutionised the diagnosis, management and treatment of many serious diseases such as cancer, heart disease and stroke. It is also beginning to play a key role in neurological disorders such as Parkinson and Alzheimers disease and epilepsy. More recently there has been considerable growth in the application of nuclear medicine to treat sport-related injuries - especially wrist, ankle and knees where more common techniques do not always enable accurate diagnosis. Australia is a recognised leader in nuclear medicine. This can be partially attributed to the close relationship between ANSTO and the medical community in providing opportunities to develop and evaluate new agents to support more effective patient care. A list of commercial isotopes produced in the reactor or the cyclotron and used in medical applications is given. Nuclear medicine plays an important role in the clinical environment and the timely supply of radioisotopes is a key element. ANSTO will continue to be the premier supplier of currently available and developing isotopes to support the health and well being of the Australian community

    2013-10-31

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

    Nisin is a bacteriocin produced by a group of Gram-positive bacteria that belongs to Lactococcus and Streptococcus species. Nisin is classified as a Type A (I) lantibiotic that is synthesized from mRNA and the translated peptide contains several unusual amino acids due to post-translational modifications. Over the past few decades, nisin has been used widely as a food biopreservative. Since then, many natural and genetically modified variants of nisin have been identified and studied for their unique antimicrobial properties. Nisin is FDA approved and generally regarded as a safe peptide with recognized potential for clinical use. Over the past two decades the application of nisin has been extended to biomedical fields. Studies have reported that nisin can prevent the growth of drug-resistant bacterial strains, such as methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae, Enterococci and Clostridium difficile. Nisin has now been shown to have antimicrobial activity against both Gram-positive and Gram-negative disease-associated pathogens. Nisin has been reported to have anti-biofilm properties and can work synergistically in combination with conventional therapeutic drugs. In addition, like host-defence peptides, nisin may activate the adaptive immune response and have an immunomodulatory role. Increasing evidence indicates that nisin can influence the growth of tumours and exhibit selective cytotoxicity towards cancer cells. Collectively, the application of nisin has advanced beyond its role as a food biopreservative. Thus, this review will describe and compare studies on nisin and provide insight into its future biomedical applications.

    2011-01-01

    Lines of code (LOC) analysis is one of the methods used to measure programmer productivity and estimate schedules of programming projects. The Launch Control System (LCS) had previously used this method to estimate the amount of work and to plan development efforts. The disadvantage of using LOC as a measure of effort is that one can only measure 30% to 35% of the total effort of software projects involves coding [8]. In the application, instead of using the LOC we are using function point for a better estimation of hours in each software to develop. Because of these disadvantages, Jamie Szafran of the System Software Branch of Control And Data Systems (NE-C3) at Kennedy Space Canter developed a web application called Function Point Analysis (FPA) Depot. The objective of this web application is that the LCS software architecture team can use the data to more accurately estimate the effort required to implement customer requirements. This paper describes the evolution of the domain model used for function point analysis as project managers continually strive to generate more accurate estimates.

  10. WAP - based telemedicine applications

    International Nuclear Information System (INIS)

    Telemedicine refers to the utilization of telecommunication technology for medical diagnosis, treatment, and patient care. Its aim is to provide expert-based health care to remote sites through telecommunication and information technologies. The significant advances in technologies have enabled the introduction of a broad range of telemedicine applications, which are supported by computer networks, wireless communication, and information superhighway. For example, some hospitals are using tele-radiology for remote consultation. Such a system includes medical imaging devices networked with computers and databases. Another growing area is patient monitoring, in which sensors are used to acquire biomedical signals, such as electrocardiogram (ECG), blood pressure, and body temperature, from a remote patient, who could be in bed or moving freely. The signals are then relayed to remote systems for viewing and analysis. Telemedicine can be divided into two basic modes of operations: real-time mode, in which the patient data can be accessed remotely in real-time, and store-and-forward mode, in which the acquired data does not have to be accessed immediately. In the recent years, many parties have demonstrated various telemedicine applications based on the Internet and cellular phone as these two fields have been developing rapidly. A current, recognizable trend in telecommunication is the convergence of wireless communication and computer network technologies. This has been reflected in recently developed telemedicine systems. For example, in 1998 J. Reponen, et al. have demonstrated transmission and display of computerized tomography (CT) examinations using a remote portable computer wirelessly connected to a computer network through TCP/IP on a GSM cellular phone. Two years later, they carried out the same tests with a GSM-based wireless personal digital assistant (PDA).

  4. Applications of Research Reactors

    International Nuclear Information System (INIS)

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.' One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property'. The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. The purpose of the earlier publication, The Application of Research Reactors, IAEA-TECDOC-1234, was to present descriptions of the typical forms of research reactor use. The necessary criteria to enable an application to be performed were outlined for each one, and, in many cases, the minimum as well as the desirable requirements were given. This revision of the publication over a decade later maintains the original purpose and now specifically takes into account the changes in service requirements demanded by the relevant stakeholders. In particular, the significant improvements in

    Ølgaard, Kristian Breum; Wells, Garth N.

    2012-01-01

    Problems in solid mechanics constitute perhaps the largest field of application of finite element methods. The vast majority of solid mechanics problems involve the standard momentum balance equation, posed in a Lagrangian setting, with different models distinguished by the choice of nonlinear...... or linearized kinematics, and the constitutive model for determining the stress. For some common models, the constitutive relationships are rather complex. This chapter addresses a number of canonical solid mechanics models in the context of automated modeling, and focuses on some pertinent issues that arise...

    Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb lattice. It was first obtained by exfoliation of graphite in 2004 and has since evolved into a thriving research topic because of its attractive mechanical, thermal, and electrical properties. Graphene's unique electrical properties derive from the relativistic nature of its quasiparticles, resulting in exceptionally high electron mobility. Graphene promises to revolutionize many applications, ranging from solar cells and light-emitting devices to touch screens, photodetectors, microwave transistors, and ultrafast lasers.

    Full Text Available The main idea behind implementing such a project is to develop a firewall system which is a network security system that doesn’t permit the user to make any modifications on the application over the network. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, thereby protecting the system from malicious attacks that could cause damage or loss of data confidentiality. It will thereby prevent the system from attackers using several mechanisms to get access to the data stored in the system.

    2010-06-01

    Cold therapy is commonly used as a procedure to relieve pain symptoms, particularly in inflammatory diseases, injuries and overuse symptoms. A peculiar form of cold therapy (or stimulation) was proposed 30 years ago for the treatment of rheumatic diseases. The therapy, called whole-body cryotherapy (WBC), consists of exposure to very cold air that is maintained at -110 degrees C to -140 degrees C in special temperature-controlled cryochambers, generally for 2 minutes. WBC is used to relieve pain and inflammatory symptoms caused by numerous disorders, particularly those associated with rheumatic conditions, and is recommended for the treatment of arthritis, fibromyalgia and ankylosing spondylitis. In sports medicine, WBC has gained wider acceptance as a method to improve recovery from muscle injury. Unfortunately, there are few papers concerning the application of the treatment on athletes. The study of possible enhancement of recovery from injuries and possible modification of physiological parameters, taking into consideration the limits imposed by antidoping rules, is crucial for athletes and sports physicians for judging the real benefits and/or limits of WBC. According to the available literature, WBC is not harmful or detrimental in healthy subjects. The treatment does not enhance bone marrow production and could reduce the sport-induced haemolysis. WBC induces oxidative stress, but at a low level. Repeated treatments are apparently not able to induce cumulative effects; on the contrary, adaptive changes on antioxidant status are elicited--the adaptation is evident where WBC precedes or accompanies intense training. WBC is not characterized by modifications of immunological markers and leukocytes, and it seems to not be harmful to the immunological system. The WBC effect is probably linked to the modifications of immunological molecules having paracrine effects, and not to systemic immunological functions. In fact, there is an increase in anti

    International Nuclear Information System (INIS)

    Experiments were carried out on mice and the subjects irradiated for cancer therapy to evaluate the protective efficacy of a Chinese medicinal herb-compound (CMHC). The lethality and the degree of leucopenia caused by radiation in mice medicated with CMHC were significantly less in comparison with control mice (p less than 0.01 and p less than 0.001, respectively). CMHC significantly improved the WBC and the thrombocytes in irradiated workers (p less than 0.01 and p less than 0.001, respectively). The WBC count of 40 patients under radiotherapy while treated with CMHC recovered from 3450 +/- 77/c.mm to 5425 +/- 264/c.mm (p less than 0.001); whereas, in the control group, without any medication, the WBC count dropped significantly (p less than 0.001). Our results revealed the applicabilities of CMHC in protection against radiation damage in spaceflight and in other fields

    Microneedle mediated microporation has proved its potential to enhance the delivery of therapeutic drug molecules through skin over the last one decade. Several patents have been granted and cutting edge research is going on particularly for the delivery of biopharmaceuticals (macromolecules like protein or peptides). The technology involves use of micron sized needles made of diverse materials to form microchannels into the stratum corneum (or deeper), outermost barrier layer of the skin. These microchannels are deep enough to facilitate efficient drug delivery through disrupted stratum corneum but short enough to avoid bleeding or pain. So far, the microneedle technology has been explored for drug and vaccine delivery through transcutaneous route. However, the miniaturized nature of these microneedles and anticipated minimal invasiveness has led the scientists to explore and patent its possible use for several other applications.The use of this technology in combination with other enhancement techniques has also gained recent attention. This review article focuses on the latest developments in the field of microneedles as described in patent and research literature. Comprehensive review of several topics including device design/fabrication, formulation development, safety/regulatory issues, therapeutic applications and major challenges in the commercialization of microneedles as medical devices has been presented here.

    2009-02-01

    Modern material design involves a close collaboration between experimental and computational materials scientists. To be useful, the theory must be able to accurately predict the stability and properties of new materials, describe the physics of the experiments, and be applicable to new and complex structures—the all-electron full-potential linearized augmented plane wave (FLAPW) is one such method that provides the requisite level of numerical accuracy, albeit at the cost of complexity. Technical aspects and modifications related to the choice of basis functions (energy parameters, core-valence orthogonality, extended local orbitals) that affect the applicability and accuracy of the method are described, as well as an approach for obtaining k-independent matrix elements. The inclusion of external electric fields is illustrated by results for the induced densities at the surfaces of both magnetic and non-magnetic metals, and the relationship to image planes and to nonlinear effects such as second harmonic generation. The magnetic coupling of core hole excitations in Fe, the calculation of intrinsic defect formation energies, the concentration-dependent chemical potentials, entropic contributions, and the relative phase stability of Zr-rich Zr-Al alloys are also discussed.

  2. Applications of Groundwater Helium

    Kulongoski, Justin T.; Hilton, David R.

    2011-01-01

    Helium abundance and isotope variations have widespread application in groundwater-related studies. This stems from the inert nature of this noble gas and the fact that its two isotopes ? helium-3 and helium-4 ? have distinct origins and vary widely in different terrestrial reservoirs. These attributes allow He concentrations and 3He/4He isotope ratios to be used to recognize and quantify the influence of a number of potential contributors to the total He budget of a groundwater sample. These are atmospheric components, such as air-equilibrated and air-entrained He, as well as terrigenic components, including in situ (aquifer) He, deep crustal and/or mantle He and tritiogenic 3He. Each of these components can be exploited to reveal information on a number of topics, from groundwater chronology, through degassing of the Earth?s crust to the role of faults in the transfer of mantle-derived volatiles to the surface. In this review, we present a guide to how groundwater He is collected from aquifer systems and quantitatively measured in the laboratory. We then illustrate the approach of resolving the measured He characteristics into its component structures using assumptions of endmember compositions. This is followed by a discussion of the application of groundwater He to the types of topics mentioned above using case studies from aquifers in California and Australia. Finally, we present possible future research directions involving dissolved He in groundwater.

    In dental hard tissue ablation, ultra-short laser pulses have proven sufficiently their potential for material ablation with negligible collateral damage providing many advantages. The absence of micro-cracks and the possibility to avoid overheating of the pulp during dental cavity preparation may be among the most important issues, the latter opening up an avenue for potential painless treatment. Beside the evident short interaction time of laser radiation with the irradiated tissue, scanning of the ultra-short pulse trains turned out to be crucial for ablating cavities of required quality and shape. Additionally, long-pulsed laser systems have demonstrated successfully their suitability for decontamination purposes. In this paper, an overview of different indications for laser application in dental therapies in both pulse regimes is presented. A special focus is set on the decontamination of dental implants in periimplantitis therapy. Having employed commercially available long pulse systems for dental applications and ultra-short 330 fs pulses, we present first results for temperature development and corresponding ablation thresholds for dental implants, as in the future more gentle implant cleaning by ultra-short laser pulses could become of interest.

    Ambrosi, Christina M; Klimas, Aleksandra; Yu, Jinzhu; Entcheva, Emilia

    2014-08-01

    In complex multicellular systems, such as the brain or the heart, the ability to selectively perturb and observe the response of individual components at the cellular level and with millisecond resolution in time, is essential for mechanistic understanding of function. Optogenetics uses genetic encoding of light sensitivity (by the expression of microbial opsins) to provide such capabilities for manipulation, recording, and control by light with cell specificity and high spatiotemporal resolution. As an optical approach, it is inherently scalable for remote and parallel interrogation of biological function at the tissue level; with implantable miniaturized devices, the technique is uniquely suitable for in vivo tracking of function, as illustrated by numerous applications in the brain. Its expansion into the cardiac area has been slow. Here, using examples from published research and original data, we focus on optogenetics applications to cardiac electrophysiology, specifically dealing with the ability to manipulate membrane voltage by light with implications for cardiac pacing, cardioversion, cell communication, and arrhythmia research, in general. We discuss gene and cell delivery methods of inscribing light sensitivity in cardiac tissue, functionality of the light-sensitive ion channels within different types of cardiac cells, utility in probing electrical coupling between different cell types, approaches and design solutions to all-optical electrophysiology by the combination of optogenetic sensors and actuators, and specific challenges in moving towards in vivo cardiac optogenetics.

  5. Applications of high power microwaves

    International Nuclear Information System (INIS)

    The authors address a number of applications for HPM technology. There is a strong symbiotic relationship between a developing technology and its emerging applications. New technologies can generate new applications. Conversely, applications can demand development of new technological capability. High-power microwave generating systems come with size and weight penalties and problems associated with the x-radiation and collection of the electron beam. Acceptance of these difficulties requires the identification of a set of applications for which high-power operation is either demanded or results in significant improvements in peRFormance. The authors identify the following applications, and discuss their requirements and operational issues: (1) High-energy RF acceleration; (2) Atmospheric modification (both to produce artificial ionospheric mirrors for radio waves and to save the ozone layer); (3) Radar; (4) Electronic warfare; and (5) Laser pumping. In addition, they discuss several applications requiring high average power than border on HPM, power beaming and plasma heating

    A new formalism of beam-optics and polarization has been recently presented, based on an exact matrix representation of the Maxwell equations. This is described in Part-I and Part-II. In this Part, we present the application of the above formalism to the specific example of the axially symmetric graded index fiber. This formalism leads to the wavelength-dependent modifications of the six aberrations present in the traditional prescriptions and further gives rise to the remaining three aberrations permitted by the axial symmetry. Besides, it also gives rise to a wavelength-dependent image rotation. The three extra aberrations and the image rotation are not found in any of the traditional approaches.

    2009-01-01

    In this paper we report the recent advances in nanodielectrics that were developed and tested for cryogenic dielectric applications. The systems studied are composed of nanometer size particles. Particles were produced using either an ex-situ or in-situ technique. It is observed that there are clear differences in the structural properties of materials produced using these two approaches. Either no significant degradation or improvement in the electrical insulation properties were observed for ex-situ nano-particle samples processed with an ultrasonic processor and in-situ nano-particle samples. Nanodielectrics have the potential to be tailored with better thermal and mechanical properties without losing their electrical insulation characteristics.

    Sunvestment Energy Group (previously called Sunvestment Group) was established to create a web application that brings together site hosts, those who will obtain the energy from the solar array, with project developers and funders, including affinity investors. Sunvestment Energy Group (SEG) uses a community-based model that engages with investors who have some affinity with the site host organization. In addition to a financial return, these investors receive non-financial value from their investments and are therefore willing to offer lower cost capital. This enables the site host to enjoy more savings from solar through these less expensive Community Power Purchase Agreements (CPPAs). The purpose of this award was to develop an online platform to bring site hosts and investors together virtually.

    2016-01-01

    Glaucoma is the second leading cause of blindness worldwide, and the antiglaucoma treatments currently available suffer from various complications. Nanotechnology-based treatments show a great deal of promise in overcoming these complications and form the basis for next-generation glaucoma treatment strategies, with the help of applications such as controlled release, targeted delivery, increased bioavailability, diffusion limitations, and biocompatibility. Significant progress has been made in nanomedicine in the efficiency of antiglaucoma medications, nanofabrication systems such as microelectromechanical systems that remove the limitations of nanodevices, and tissue regeneration vesicles for developing glaucoma treatments not based on intraocular pressure. With the use of these advanced technologies, the prevention of glaucoma-induced blindness will be possible in the near future. Herein, we reviewed the recent advances in nanotechnology-based treatment strategies for glaucoma. PMID:26693592

  5. Applications of Metric Coinduction

    CERN Document Server

    Kozen, Dexter

    2009-01-01

    Metric coinduction is a form of coinduction that can be used to establish properties of objects constructed as a limit of finite approximations. One can prove a coinduction step showing that some property is preserved by one step of the approximation process, then automatically infer by the coinduction principle that the property holds of the limit object. This can often be used to avoid complicated analytic arguments involving limits and convergence, replacing them with simpler algebraic arguments. This paper examines the application of this principle in a variety of areas, including infinite streams, Markov chains, Markov decision processes, and non-well-founded sets. These results point to the usefulness of coinduction as a general proof technique.

  6. Laser applications in neurosurgery

    Science.gov (United States)

    Cerullo, Leonard J.

    1985-09-01

    The "false start" of the laser in neurosurgery should not be misconstrued as a denial of the inherent advantages of precision and gentleness in dealing with neural tissue. Rather, early investigators were frustrated by unrealistic expectations, cumbersome equipment, and a general ignorance of microtechnique. By the early 70s, microneurosurgery was well established, surgical laser equipment for free hand and microlinked application had been developed, and a more realistic view of the limitations of the laser had been established. Consequently, the late 70s really heralded the renaissance of the laser in neurosurgery. Since then, there has been an overwhelming acceptance of the tool in a variety of clinical situations, broadly categorized in five groups. 1)|Perhaps the most generally accepted area is in the removal of extra-axial tumors of the brain and spinal cord. These tumors, benign by histology but treacherous by location, do not present until a significant amount of neurological compensation has already occurred. The application of additional trauma to the neural tissue, whether by further tumor growth or surgical manipulation, frequently results in irreversible damage. Here, the ability of the laser to vaporize tissue, in a fairly hemostatic fashion, without mechanical or thermal damage to sensitive surrounding tissues, is essential. 2)|The ability to incise delicate neural tissue with minimal spread of thermal destruction to adjacent functioning tissue makes the laser the ideal instrument when tumors deep under the surface are encountered in the brain or spinal cord. Thus, the second group of applications is in the transgression of normal neural structures to arrive at deeper pathological tissue. 3)|The third area of benefit for the laser in neurosurgery has been in the performance of neuroablative procedures, calling for deliberate destruction of functioning neural tissue in a controlled fashion. Again, the precision and shape confinement of the destructive

  8. Nuclear applications for development

    International Nuclear Information System (INIS)

    Building capacity for the safe application of nuclear technologies produces tangible socioeconomic benefits to developing countries. Identifying killer infections such as extrapulmonary tuberculosis and drug resistant strains of HIV/AIDS in sub-Saharan Africa; Monitoring malaria drug resistance in Myanmar; - Teaching Jordanian farmers how to produce viable crops on salty soils; - Investigating water resources deep beneath the Nubian Desert; - Fighting acid rain in Poland; - Creating an energy strategy for Latin America; - Strengthening the security of nuclear sources in Kazakhstan. These are just some of examples of the practical ways in which the International Atomic Energy Agency (IAEA) fulfils its mandate to 'accelerate and enlarge the contribution of atomic energy to peace, health, and prosperity throughout the world'. And some of the reasons the IAEA's long history of global action was recognized through the Nobel Peace Prize in 2005. This list of activities reflects the diverse needs of Member States. It also demonstrates the enormous potential of nuclear technology and the breadth of expertise that lie within three IAEA technical programmes: Nuclear Sciences and Applications, Nuclear Energy, and Nuclear Safety and Security. More importantly, it speaks to the success of a determined effort to facilitate knowledge sharing and technology transfer through a cross-cutting mechanism known as the technical cooperation programme. Each year, the technical cooperation programme disburses approximately US $90 million, all of which is acquired through voluntary contributions from Member States. The programme concentrates on building capacity through training and education, expert advice, and equipment delivery. It is currently active in more than 110 countries across four geographic regions: Africa, Asia and the Pacific, Europe and Latin America

  9. Insulators for fusion applications

    International Nuclear Information System (INIS)

    Design studies for fusion devices and reactors have become more detailed in recent years and with this has come a better understanding of requirements and operating conditions for insulators in these machines. Ceramic and organic insulators are widely used for many components of fusion devices and reactors namely: radio frequency (RF) energy injection systems (BeO, Al2O3, Mg Al2O4, Si3N4); electrical insulation for the torus structure (SiC, Al2O3, MgO, Mg Al2O4, Si4Al2O2N6, Si3N4, Y2O3); lightly-shielded magnetic coils (MgO, MgAl2O4); the toroidal field coil (epoxies, polyimides), neutron shield (B4C, TiH2); high efficiency electrical generation; as well as the generation of very high temperatures for high efficiency hydrogen production processes (ZrO2 and Al2O3 - mat, graphite and carbon - felt). Timely development of insulators for fusion applications is clearly necessary. Those materials to be used in fusion machines should show high resistance to radiation damage and maintain their structural integrity. Now the need is urgent for a variety of radiation resistant materials, but much effort in these areas is required for insulators to be considered seriously by the design community. This document contains 14 papers from an IAEA meeting. It was the objective of this meeting to identify existing problems in analysing various situations of applications and requirements of electrical insulators and ceramics in fusion and to recommend strategies and different stages of implementation. This meeting was endorsed by the International Fusion Research Council

    Kania, Don R

    1995-01-01

    The use of diamond in electronic applications is not a new idea, but limitations in size and control of properties restricted the use of diamond to a few specialised applications. The vapour-phase synthesis of diamond, however, has facilitated serious interest in the development of diamond-based electronic devices. The process allows diamond films to be laid down over large areas. Both intrinsic and doped diamond films have a unique combination of extreme properties for high speed, high power and high temperature applications. The eleven chapters in Diamond: Electronic Properties and Applications, written by the world's foremost experts on the subject, give a complete characterisation of the material, in both intrinsic and doped forms, explain how to grow it for electronic applications, how to use the grown material, and a description of both passive and active devices in which it has been used with success. Diamond: Electronic Properties and Applications is a compendium of the available literature on the sub...

    Requirement for deaf mobile applications need to be analysed to ensure the disabilities need are instilled into the mobile applications developed for them. Universal design is understandable to comply every user needs, however specific disability is argued by the authors to have different need and requirements. These differences are among the reasons for these applications being developed to target for a specific group of people, however they are less usable and later abandoned. This study focuses on deriving requirements that are needed by the deaf in their mobile applications that are meant specifically for them. Studies on previous literature was conducted it can be concluded that graphic, text, multimedia and sign language interpreter are among mostly required features to be included in their mobile application to ensure the applications are usable for this community.

  9. Environmental applications of ultrasound

    Science.gov (United States)

    Oxley, James Dean

    The application of ultrasound to environmental problems relies on the process of acoustic cavitation: the formation, growth, and implosive collapse of bubbles in a liquid. The collapse of such bubbles creates hot spots with temperatures as high as 5000 K, pressures up to 800 atm, and cooling rates in excess of 1010K/s. This thesis describes the use of ultrasound for the dissolution of gas into water, an investigation the sonochemistry of ionic liquids, and the sonochemical preparation of nanostructured materials for the catalytic hydrodehalogenation of organic halides. A variety of ultrasonic methods and configurations were designed and tested for the dispersion and dissolution of O2 in water. Ultrasonic methods examined include 20 kHz Ti horns, 336 to 1.41 MHz transducers, specially designed ultrasonic gas dispersion cell including the hollow horn extensions, Ti frits, and a modified 20 kHz cup horn. Most methods increased the dispersion rate when compared to non-ultrasonic control runs. Room-temperature ionic liquids were examined for their potential application as green solvents for sonochemical reactions. The effects of ultrasound on room-temperature ionic liquids were investigated using butylmethyl imidazolium chloride (BuMeImCl), butylmethyl imidazolium tetrafluoroborate (BuMeImBF 4), and decylmethyl imidazolium tetraphenylborate. Gas-chromatography mass-spectrometry head-gas analysis and multibubble sonoluminescence were used to show that room-temperature ionic liquids decomposed in the presence of ultrasound. As previously reported, molybdenum carbonyl and tungsten carbonyl were decomposed sonochemically in hexadecane to form porous aggregates of 2--3 nm high surface area Mo2C and W2C particles. The activity of these materials was studied for the catalytic hydrodehalogenation of aliphatic and aromatic halocarbons at low temperatures (T = 200--300°C). Both catalysts were selective, active, and stable for all substrates tested. The HDH of substrates bearing

  12. Phytosanitary applications of irradiation

    International Nuclear Information System (INIS)

    Phytosanitary treatments are used to disinfest agricultural commodities of quarantine pests so that the commodities can be shipped out of quarantined areas. Ionizing irradiation is a promising phytosanitary treatment that is in- creasing in use worldwide. Almost 19000 metric tons of sweet potatoes and several fruits plus a small amount of curry leaf are irradiated each year in 6 countries, including the United States, to control a number of plant quarantine pests. Advantages over other treatments include tolerance by most fresh commodities, ability to treat in the final packaging and in pallet loads, and absence of pesticide residues. A regulatory disadvantage is lack of an independent verification of treatment efficacy because pests may be found alive during commodity inspection, although they will not complete development or reproduce. High-energy X-rays generated by electron beam are ideal for sterilizing large packages and pallet loads of food. The directional concentration and high penetration capability as well as excellent dose uniformity of X-rays allows disinfest efficiently. Application of irradiation phytosanitary in China still in its infancy. (authors)

  14. Industrial application of adaptronics

    Wimmel, R. [ERAS GmbH, Goettingen (Germany)

    2000-07-01

    The innovation aims in machine building with regard to product quality and throughput are to increase the accuracy, the velocity and the size in the first place. However, the accuracy of a process is questioned by an enlargement of the velocity if one considers that the excitation amplitudes increase for all vibration phenomena with increasing velocity. The demand to increase throughput by means of larger system widths normally leads to a mass increase and a stiffness reduction at the same time. Therefore, it must be an important aim to make use of lightweight construction designs for these applications. However, the potential of lightweight construction technology is limited by lower damping referring to vibration problems. Summarizingly it can be stated that for the future the vibration behavior of machines has to be moved into the centre of dimensioning since the innovation aims are currently not achieved due to vibration problems. The useful way to overcome the design dilemma with active systems will be shown herein at the example of an aggregate of the worlds largest wood-free coated paper production line. (orig.)

  16. Techniques for Wireless Applications

    KAUST Repository

    Gaaloul, Fakhreddine

    2012-05-01

    Switching techniques have been first proposed as a spacial diversity techniques. These techniques have been shown to reduce considerably the processing load while letting multi-antenna systems achieve a specific target performance. In this thesis, we take a different look at the switching schemes by implementing them for different other wireless applications. More specifically, this thesis consists of three main parts, where the first part considers a multiuser environment and an adaptive scheduling algorithm based on the switching with post-selection scheme for statistically independent but non-identically distributed channel conditions. The performance of this switched based scheduler is investigated and a multitude of performance metrics are presented. In a second part, we propose and analyze the performance of three switched-based algorithms for interference reduction in the downlink of over-loaded femtocells. For instance, performance metrics are derived in closed-form and these metrics are used to compare these three proposed schemes. Finally in a third part, a switch based opportunistic channel access scheme is proposed for a cognitive radio system and its performance is analyzed in terms of two new proposed metrics namely the average cognitive radio access and the waiting time duration.

  17. Application of nuclear models

    International Nuclear Information System (INIS)

    The development of extensive experimental nuclear data base over the past three decades has been accompanied by parallel advancement of nuclear theory and models used to describe and interpret the measurements. This theoretical capability is important because of many nuclear data requirements that are still difficult, impractical, or even impossible to meet with present experimental techniques. Examples of such data needs are neutron cross sections for unstable fission products, which are required for neutron absorption corrections in reactor calculations; cross sections for transactinide nuclei that control production of long-lived nuclear wastes; and the extensive dosimetry, activation, and neutronic data requirements to 40 MeV that must accompany development of the Fusion Materials Irradation Test (FMIT) facility. In recent years systematic improvements have been made in the nuclear models and codes used in data evaluation and, most importantly, in the methods used to derive physically based parameters for model calculations. The newly issued ENDF/B-V evaluated data library relies in many cases on nuclear reaction theory based on compound-nucleus Hauser-Feshbach, preequilibrium and direct reaction mechanisms as well as spherical and deformed optical-model theories. The development and applications of nuclear models for data evaluation are discussed with emphasis on the 1 to 40 MeV neutron energy range

  18. Applications of chiral symmetry

    Energy Technology Data Exchange (ETDEWEB)

    Pisarski, R.D.

    1995-03-01

    The author discusses several topics in the applications of chiral symmetry at nonzero temperature. First, where does the rho go? The answer: up. The restoration of chiral symmetry at a temperature T{sub {chi}} implies that the {rho} and a{sub 1} vector mesons are degenerate in mass. In a gauged linear sigma model the {rho} mass increases with temperature, m{sub {rho}}(T{sub {chi}}) > m{sub {rho}}(0). The author conjectures that at T{sub {chi}} the thermal {rho} - a{sub 1}, peak is relatively high, at about {approximately}1 GeV, with a width approximately that at zero temperature (up to standard kinematic factors). The {omega} meson also increases in mass, nearly degenerate with the {rho}, but its width grows dramatically with temperature, increasing to at least {approximately}100 MeV by T{sub {chi}}. The author also stresses how utterly remarkable the principle of vector meson dominance is, when viewed from the modern perspective of the renormalization group. Secondly, he discusses the possible appearance of disoriented chiral condensates from {open_quotes}quenched{close_quotes} heavy ion collisions. It appears difficult to obtain large domains of disoriented chiral condensates in the standard two flavor model. This leads to the last topic, which is the phase diagram for QCD with three flavors, and its proximity to the chiral critical point. QCD may be very near this chiral critical point, and one might thereby generated large domains of disoriented chiral condensates.

  19. Thermoluminescence - physics and applications

    International Nuclear Information System (INIS)

    The interaction of ionizing radiations with matter leads to various effects, some of which leave memory in the target material. These memory effects can be seen as the after-effects of the irradiation. Thermoluminescence is one such phenomenon in the insulating solids. This paper describes the sequence of the physical events beginning with the incidence of an ionizing particle, leading to a trail of atomic and electronic displacements which stabilize in the form of so called defect centres. These defects - interstitials, colour centres, etc., store energy in their configuration. Most of the damage effects are reversible. The return of the displaced entities to their original site leads to the release of the stored energy. Thermoluminescence is the result of the re-adjustment (relaxation) of the displaced electrons. The stimulation for the relaxation process is provided by heating of the irradiated sample. The kinetics of the thermoluminescence process has been explained phenomenologically. The correspondence between the defect centres and the TL glow peaks has remained vague or ambiguous even in the most widely studied TL materials. Notwithstanding this deficiency, the phenomenon has found many practical applications. The paper deals mainly with the physical processes involved in the TL emission and alludes briefly to its involvement in applied areas.(author). 6 refs., 2 figs

    Full Text Available Microencapsulation technology allows a compound to be encapsulated inside a tiny sphere known as microsphere/microcapsule, having an average diameter as small as 1 mm to several hundred micro meters. Many different active materials like drugs, enzymes, vitamins, pesticides, flavours and catalysts have been successfully encapsulated inside microballoons or microcapsules made from a variety of polymeric and non polymeric materials including poly(ethylene glycols, poly(methacrylates, poly(styrenes, cellulose, poly(lactides, poly(lactide-co-glycolides, gelatin and acacia, etc. These microcapsules release their contents at appropriate time by using different release mechanisms, depending on the end use of encapsulated products. This technology has been used in several fields including pharmaceutical, agriculture, food, printing, cosmetic, textile and defence. In defence sector this technology has introduced the concept of self-healing composites as well as chemical decontaminating fabrics. This review paper highlights the major reasons behind microencapsulation, important techniques of microencapsulation and application of microencapsulated products in different areas of science and technology.Defence Science Journal, 2009, 59(1, pp.82-95, DOI:http://dx.doi.org/10.14429/dsj.59.1489

    The present report describes the architecture of interface for numerical operations, peripheral input/output devices and process input/output ( P I/O) devices of microcomputer (M6800) system. As an application of such interface this paper also reports on the rod worth measurements. In the arithmetic processing system a MOS/LSI MM57109 is interfaced with a basic system of microcomputer, with common memory in such a way that decimal arithmetic operations may be performed with simple software at machine language level. This system consists of such the peripherals and P I/O devices as, Peripherals; TTY and its compatible device, Audio or Digital Cassette Recorder, CRT Character Terminal, Mini-Floppy Disk, X-Y Recorder and X-Y Plotter, P I/O; A/D Converter, Present-Timer, Pulse Counter, Digital Clock, Universal Counter, D/A Converter and the Rod Worth Interface. If each P I/O device were connected individually to I/O port, many ports and signal lines would be needed. This problem is resolved to simplify the situation by providing with control port and I/O data port, through which interface is taken for data collection and processing. Similar interface is connected to the instrumentation system of the KUR and a good result could be obtained on the rod worth measurements. (author)

    The rising count and shrinking feature size of transistors within modern computers is making them increasingly vulnerable to various types of soft faults. This problem is especially acute in high-performance computing (HPC) systems used for scientific computing, because these systems include many thousands of compute cores and nodes, all of which may be utilized in a single large-scale run. The increasing vulnerability of HPC applications to errors induced by soft faults is motivating extensive work on techniques to make these applications more resiilent to such faults, ranging from generic techniques such as replication or checkpoint/restart to algorithmspecific error detection and tolerance techniques. Effective use of such techniques requires a detailed understanding of how a given application is affected by soft faults to ensure that (i) efforts to improve application resilience are spent in the code regions most vulnerable to faults and (ii) the appropriate resilience technique is applied to each code region. This paper presents XRay, a tool to view the application vulnerability to soft errors, and illustrates how XRay can be used in the context of a representative application. In addition to providing actionable insights into application behavior XRay automatically selects the number of fault injection experiments required to provide an informative view of application behavior, ensuring that the information is statistically well-grounded without performing unnecessary experiments.

    Terahertz technology is mature enough for large-volume sensing applications. However, Dook van Mechelen says there are a few hurdles preventing its industrial debut. THz spectroscopy has a number of advantages that point to abundant industrial applications, in areas such quality control, security and biomedical imaging. Yet despite those advantages, the search for a THz "killer application"--a novel, innovative use with a business case strong enough to bring the technology into the industrial mainstream--has remained fruitless, and even the hope of finding such an application has begun to falter. Why has a killer app for THz radiation been so elusive? And how can the road to industrial application of this versatile technology be cleared?

    Nanotechnology is one of the leading scientific fields today since it combines knowledge from the fields of Physics, Chemistry, Biology, Medicine, Informatics, and Engineering. It is an emerging technological field with great potential to lead in great breakthroughs that can be applied in real life. Novel nano- and biomaterials, and nanodevices are fabricated and controlled by nanotechnology tools and techniques, which investigate and tune the properties, responses, and functions of living and non-living matter, at sizes below 100 nm. The application and use of nanomaterials in electronic and mechanical devices, in optical and magnetic components, quantum computing, tissue engineering, and other biotechnologies, with smallest features, widths well below 100 nm, are the economically most important parts of the nanotechnology nowadays and presumably in the near future. The number of nanoproducts is rapidly growing since more and more nanoengineered materials are reaching the global market The continuous revolution in nanotechnology will result in the fabrication of nanomaterials with properties and functionalities which are going to have positive changes in the lives of our citizens, be it in health, environment, electronics or any other field. In the energy generation challenge where the conventional fuel resources cannot remain the dominant energy source, taking into account the increasing consumption demand and the CO2 emissions alternative renewable energy sources based on new technologies have to be promoted. Innovative solar cell technologies that utilize nanostructured materials and composite systems such as organic photovoltaics offer great technological potential due to their attractive properties such as the potential of large-scale and low-cost roll-to-roll manufacturing processes The advances in nanomaterials necessitate parallel progress of the nanometrology tools and techniques to characterize and manipulate nanostructures.

    The article reports upon the characteristics of 300 abortion applicants in Arkansas manifesting significant stress from unwanted pregnancy between May 1, 1970 and June 30, 1971. The sample is limited by the fact that all of these women had been willing to seek medical aid. Patients ranged from ages 13-47, 131 of them ages 17-21. 35% had had some college education; another 29% were high school graduates. 50.6%, 20.6%, and 27.3% were single, divorced, and married, respectively. 59.6% of the patients were primiparas. 18.3%, 9.6%, and 12.3% were classified as being neurotic, having psychophysiologic tendencies (gastrointestinal problems, obesity, chronic headaches), and having sociopathic features (passive-aggressive, frankly rebellious, delinquent, antisocial, alcoholic), respectively. 12 women had noticeable schizoid features; 4 women had mildly active schizophrenia. Fathers of the women were usually blue-collar workers (55.3%) or white-collar workers (24.6%). The most frequent ordinal sibling position among the women was oldest child (38%). Parental instability (1 or both parents lost through death, divorce, father usually away working, chronic alcoholism, etc.) was reported by 39.6% of the patients. Patients' attitudes toward the unwanted pregnancy included dislike of inexpediency of the situation (82.6%), self-depreciation (55.6%), and aversion (28.6%). Precipitated psychiatric disorders were for the greatest part mild. Manifesting symptoms included depression (66.7%), anxiety (21%), and mixed anxiety and depression (12.2%). Suicidal threats and gestures were made by 22 and 8 patients, respectively. In summary, the study reveals a group of predominantly Caucasian women from unstable, middle-class urban families who were going through an adjustment reaction to adolescence or adult life.

    We are studying possible applications of Resistive Plate Chambers (RPCs) in the biomedical domain such as Positron Emission Tomography (PET). The use of RPCs in PET can provide several improvements on the usual scintillation-based detectors. The most striking features are the extremely good spatial and time resolutions. They can be as low as 50 {mu}m and 25 ps respectively, to be compared to the much higher intrinsic limits in bulk detectors. Much efforts have been made to investigate suitable materials to make RPCs sensitive to 511 keV photons. For this reason, we are studying different types of coating employing high Z materials with proper electrical resistivity. Later investigations explored the possibility of coating glass electrodes by mean of serigraphy techniques, employing oxide based mixtures with a high density of high Z materials; the efficiency is strongly dependent on its thickness and it reaches a maximum for a characteristic value that is a function of the compound (usually a few hundred microns). The most promising mixtures seem to be PbO, Bi{sub 2}O{sub 3} and Tl{sub 2}O. Preliminary gamma efficiency measurements for a Multigap RPC prototype (MRPC) are presented as well as simulations using GEANT4-based framework. The MRPC has 5 gas gaps; their spacings are kept by 0.3 mm diameter nylon fishing line, electrodes are made of thin glasses (1 mm for the outer electrodes, 0.15-0.4 mm for the inner ones). The detector is enclosed in a metallic gas-tight box, filled with a C{sub 2}H{sub 2}F{sub 4} 92.5%, SF{sub 6} 2.5%, C{sub 4}H{sub 10} 5% mixture. Different gas mixtures are being studied increasing the SF6 percentage and results of efficiency as a function of the new mixtures will be presented.

  6. Liver angioscintigraphy: clinical applications.

    Liver angioscintigraphy (LAS) is a radio-isotope method for the investigation of liver perfusion and its alteration in various hepatic diseases. It measures the arterial and portal venous fractions of total liver blood flow. The percentage of liver blood flow supplied by hepatic artery is estimated mathematically by the hepatic perfusion index (HPI), normally between 25 % and 40 %. The decrease of portal blood flow in liver cirrhosis is compensated ("buffer" mechanisms) by increased arterial supply, with higher HPI value. For a patient with chronic liver disease, HPI over 50% suggests arterialization of hepatic perfusion, guiding the diagnose to liver cirrhosis. Splenic curve is completing the diagnostic information of the hepatic curve. Corroborated with per rectal scintigraphy and liver SPECT, LAS offers a good hemodynamic staging of chronic inflammatory liver diseases. Malignant tumors (primitive or metastases) increase the arterial supply of the liver and decrease the portal flow, HPI being over 50% (currently 65 % - 90 %). Benign tumors do not change portal/arterial liver blood flow ratio. SPECT or non-scintigraphic morphological investigations increase the diagnostic value of LAS for primitive liver tumors. Liver cancer occurring on cirrhosis is a limitative factor for LAS. Hepatic metastases increase the arterial perfusion (and HPI value) very quickly, before their size allows morphologic imaging diagnosis. LAS is therefore an early method to diagnose liver metastases being especially used in colorectal cancer. Other clinical applications of LAS are: follow up of liver toxicity of drugs, evaluation of portal vein permeability, post surgery follow up of the liver tumor patients. PMID:15054528

  7. Security Data Warehouse Application

    Vernon, Lynn R.; Hennan, Robert; Ortiz, Chris; Gonzalez, Steve; Roane, John

    2012-01-01

    The Security Data Warehouse (SDW) is used to aggregate and correlate all JSC IT security data. This includes IT asset inventory such as operating systems and patch levels, users, user logins, remote access dial-in and VPN, and vulnerability tracking and reporting. The correlation of this data allows for an integrated understanding of current security issues and systems by providing this data in a format that associates it to an individual host. The cornerstone of the SDW is its unique host-mapping algorithm that has undergone extensive field tests, and provides a high degree of accuracy. The algorithm comprises two parts. The first part employs fuzzy logic to derive a best-guess host assignment using incomplete sensor data. The second part is logic to identify and correct errors in the database, based on subsequent, more complete data. Host records are automatically split or merged, as appropriate. The process had to be refined and thoroughly tested before the SDW deployment was feasible. Complexity was increased by adding the dimension of time. The SDW correlates all data with its relationship to time. This lends support to forensic investigations, audits, and overall situational awareness. Another important feature of the SDW architecture is that all of the underlying complexities of the data model and host-mapping algorithm are encapsulated in an easy-to-use and understandable Perl language Application Programming Interface (API). This allows the SDW to be quickly augmented with additional sensors using minimal coding and testing. It also supports rapid generation of ad hoc reports and integration with other information systems.

  8. Advances in lidar applications

    Lewandowski, Piotr Andrzej

    Quantitative laser remote sensing (lidar) measurements have always posed a challenge for the research community. The complexity of the data inversion and the instrumentation itself makes lidar results difficult to interpret. This dissertation presents a suite of 3 elastic lidar experiments. The goal of these studies was to quantitatively approach atmospheric physical phenomena such as rainfall (chapter 3), a distribution of concentration of particulates in Mexico City (chapter 4) and emission rates and emission factors from an agricultural facility in Iowa (chapter 5). The studies demonstrate that elastic lidar measurements are possible not only in a qualitative sense but also in a quantitative sense. The lidar study of rainfall was intended to provide rainfall data in small spatial and temporal scales (1.5m and 1s resolution). The two levels of lidar inversion algorithms allowed the calculation of rainfall rates in small scales. The problem of the distribution of particles over Mexico City required mobile lidar measurements. The elastic lidar data were successfully inverted to extinction coefficients which were then combined with aerosol size distribution. As a result, a spatial distribution of particulate concentration was created to illustrate the transport processes and intensity of Mexico City pollution. The measurements of particulate emission fluxes from a livestock facility involved a stationary scanning elastic lidar, in-situ aerosol size distribution measurements and wind measurements. The data from the 3 independent measurement platforms combined together resulted in emission rates and emission factors. The results from this experiment demonstrated that the new lidar approach is an adequate tool for measurement of aerosol emissions from livestock production facilities. The studies presented in the dissertation show quantitative lidar measurements in combination with other instruments measurements. This approach significantly extends the applications of

  9. Java Application Shell: A Framework for Piecing Together Java Applications

    Miller, Philip; Powers, Edward I. (Technical Monitor)

    2001-01-01

    This session describes the architecture of Java Application Shell (JAS), a Swing-based framework for developing interactive Java applications. Java Application Shell is being developed by Commerce One, Inc. for NASA Goddard Space Flight Center Code 588. The purpose of JAS is to provide a framework for the development of Java applications, providing features that enable the development process to be more efficient, consistent and flexible. Fundamentally, JAS is based upon an architecture where an application is considered a collection of 'plugins'. In turn, a plug-in is a collection of Swing actions defined using XML and packaged in a jar file. Plug-ins may be local to the host platform or remotely-accessible through HTTP. Local and remote plugins are automatically discovered by JAS upon application startup; plugins may also be loaded dynamically without having to re-start the application. Using Extensible Markup Language (XML) to define actions, as opposed to hardcoding them in application logic, allows easier customization of application-specific operations by separating application logic from presentation. Through XML, a developer defines an action that may appear on any number of menus, toolbars, and buttons. Actions maintain and propagate enable/disable states and specify icons, tool-tips, titles, etc. Furthermore, JAS allows actions to be implemented using various scripting languages through the use of IBM's Bean Scripting Framework. Scripted action implementation is seamless to the end-user. In addition to action implementation, scripts may be used for application and unit-level testing. In the case of application-level testing, JAS has hooks to assist a script in simulating end-user input. JAS also provides property and user preference management, JavaHelp, Undo/Redo, Multi-Document Interface, Single-Document Interface, printing, and logging. Finally, Jini technology has also been included into the framework by means of a Jini services browser and the

    Meyer, Steven

    2011-01-01

    Mobile application markets facilitate the distribution of applications and thus help developers advertise their work and customers find useful applications. In addition, the operators of mobile application markets can control the quality and the content of the applications. These markets are growing rapidly with more than 300'000 application in the App Store of Apple and more than 100'000 in the Android Market of Google. This is not only a great opportunity for phone manufacturers to earn money but also for indie developers (single or small teams of developers with small financial support) who can thus have a great distribution channel. Steve Demeter, the Trim game developer for iPhone, became millionaire with a single puzzle game . Obviously, as new markets generate a lot of money, the temptation of misbehavior to steal part of the benefits is big. The first famous case was the one of Molinker who self-rated his applications with 5 stars to pump up his ranking in order to increase its revenue stream. In this...

    2008-01-01

    Full Text Available For distributed applications, we define the linear, tree and graph structure types with different variants and modalities to aggregate them. The distributed applications have assigned structures that through their characteristics influence the costs of stages for developing cycle and the costs for exploitation, transferred to each user. We also present the quality characteristics of a structure for a stable application, which is focused on stability characteristic. For that characteristic we define the estimated measure indicators for a level. The influence of the factors of stability and the ways for increasing it are thus identified, and at the same time the costs of development stages, the costs of usage and the costs of maintenance to be keep on between limits that assure the global efficiency of application. It is presented the base aspects for distributed applications: definition, peculiarities and importance. The aspects for the development cycle of distributed application are detailed. In this article, we alongside give the mechanisms for building the defined structures and analyze the complexity of the defined structures for a distributed application of a virtual store.

  13. Applications of Quantum Groups

    Science.gov (United States)

    Chryssomalakos, Chryssomalis

    The main theme of this thesis is the search for applications of Quantum Group and Hopf algebraic concepts and techniques in Physics. We investigate in particular the possibilities that exist in deforming, in a self consistent way, the symmetry structure of physical theories with the hope that the resulting scheme will be of relevance in the description of physical reality. Our choice of topics reflects this motivation: we discuss deformations of rotations and Lorentz boosts, search for integrals on the quantum plane and attempt to Fourier transform functions of non -commuting coordinates. Along the way, more formal considerations prompt us to revisit integration on finite dimensional Hopf algebras, explore the interconnections between various descriptions of the quantum double and derive the algebraic structure of the quantum plane from that of the underlying deformed symmetry group. The material is structured as follows. Chapter 1 introduces the language, basic concepts and notation employed throughout this thesis. Chapter 2 focuses on Hopf algebras viewed as universal envelopes of deformed Lie algebras and their duals. Bicovariant generators enter the discussion as analogues of the classical Lie algebra generators and some of their properties are given. We comment on the geometrical interpretation of the algebraic formulation and introduce computational tools. In chapter 3 we take a close look at the quantum Lorentz Hopf algebra. The basics of complex quantum groups are presented and applied in the derivation of the algebra of the quantum Lorentz generators and its Hopf and involutive structures. We point also to isomorphisms with previous related constructions. The subject of quantum integration is explored in chapter 4. We derive a formula for the integral on a finite dimensional Hopf algebra and show its equivalence to the formulation in terms of the trace of the square of the antipode. Integration on the quantum plane is also examined and a Fourier transform

    Surface electrical geophysical methods have been used in such engineering applications as locating and delineating shallow gravel deposits, depth to bedrock, faults, clay zones, and other geological phenomena. Other engineering applications include determining water quality, tracing ground water contaminant plumes and locating dam seepages. Various methods and electrode arrays are employed to solve particular geological problems. The sensitivity of a particular method or electrode array depends upon the physics on which the method is based, the array geometry, the electrical contrast between the target and host materials, and the depth to the target. Each of the available electrical methods has its own particular advantages and applications which the paper discusses.

    1986-01-01

    In recent years, the fusion program has made a great deal of progress on the understanding of plasma physics. The primary mission of the fusion program in the past has been the generation of central station electricity. The demand for electricity, however, has slackened in recent years, fossil fuel prices are low, and the need to develop an assured, economical, long-term energy supply for the United States is no longer perceived as an immediate need. Fusion has the potential for a wide variety of nonelectric application including the breeding of fissile fuels and tritium, production of hydrogen and other chemical products, transmutation or burning of various nuclear and chemical products, transmutation or burning of various nuclear and chemical wastes, generation of process heat, production of many useful radioisotopes, radiation processing of materials, medical diagnosis and treatment, and space power and propulsion. To understand the many possible applications of fusion, GA Technologies has begun a fusion applications study for the U.S. Department of Energy's Office of Fusion Energy (DOE OFE) called FAME for Fusion Applications and Market Evaluation. The objective of this project is to investigate, evaluate, and summarize the potential applications of fusion energy, and to identify promising directions for future work on fusion applications. This study includes a broad survey of the possible uses of fusion and the products that could be obtained from a fusion reactor. The potential markets for these products are being assessed. 1 ref.

    Cleland, M R

    2006-01-01

    This paper addresses the industrial applications of electron accelerators for modifying the physical, chemical or biological properties of materials and commercial products by treatment with ionizing radiation. Many beneficial effects can be obtained with these methods, which are known as radiation processing. The earliest practical applications occurred during the 1950s, and the business of radiation processing has been expanding since that time. The most prevalent applications are the modification of many different plastic and rubber products and the sterilization of single-use medical devices. Emerging applications are the pasteurization and preservation of foods and the treatment of toxic industrial wastes. Industrial accelerators can now provide electron energies greater than 10 MeV and average beam powers as high as 700 kW. The availability of high-energy, high-power electron beams is stimulating interest in the use of X-rays (bremsstrahlung) as an alternative to gamma rays from radioactive nuclides.

    Realistic engineering simulation data often have features that are not optimally resolved due to practical limitations on mesh resolution. To be useful to application engineers, vortex characterization techniques must be sufficiently robust to handle realistic data with complex vortex topologies. In this paper, we present enhancements to the vortex topology identification component of an existing vortex characterization algorithm. The modified techniques are demonstrated by application to three realistic data sets that illustrate the strengths and weaknesses of our approach.

    2016-07-01

    Many adolescents and adults do not seek treatment for mental health symptoms. Smartphone applications (apps) may assist individuals with mental health concerns in alleviating symptoms or increasing understanding. This study seeks to characterize apps readily available to smartphone users seeking mental health information and/or support. Ten key terms were searched in the Apple iTunes and Google Play stores: mental health, depression, anxiety, schizophrenia, bipolar, trauma, trauma in schools, post traumatic stress disorder (PTSD), child trauma, and bullying. A content analysis of the first 20 application descriptions retrieved per category was conducted. Out of 300 nonduplicate applications, 208 (70%) were relevant to search topic, mental health or stress. The most common purported purpose for the apps was symptom relief (41%; n = 85) and general mental health education (18%; n = 37). The most frequently mentioned approaches to improving mental health were those that may benefit only milder symptoms such as relaxation (21%; n = 43). Most app descriptions did not include information to substantiate stated effectiveness of the application (59%; n = 123) and had no mention of privacy or security (89%; n = 185). Due to uncertainty of the helpfulness of readily available mental health applications, clinicians working with mental health patients should inquire about and provide guidance on application use, and patients should have access to ways to assess the potential utility of these applications. Strategic policy and research developments are likely needed to equip patients with applications for mental health, which are patient centered and evidence based. PMID:27428034
