  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

  7. 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

  11. 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.

    Cryotherapy is the application of a stimulus of a cryotherapeutic temperature below -100 °C in a period of 1-3 min in order to stimulate and use physiological reactions of human body to cold. It can be applied to specific body parts or to a whole body. Whole-body cryotherapy is a treatment method applied in treatment of motor organ issues, nervous system diseases, psychiatry, dermatology and laryngology. The research group consisted of 80 male in the age range of 65-77 suffering from chronic, lasting more than 3 months, lower back pain. The subjects qualified to the research were divided into two groups. Group A consisted of 40 patients who participated in whole-body cryotherapy (WBC) twice a week. Group B also contained 40 patients who participated in WBC whole week. Examinations were conducted twice. The first one was conducted before the commencement of the treatment while the second one after the therapy was over. The results of the research did not show any statistically significant improvement in patients from Group A. However, the results obtained by Group B have proven significant condition improvement and enable the researchers to conclude that WBC is effective in treating patients with lower back pain.

    Whole body cryotherapy (WBC) consists of a brief exposure to extreme cold air (-110°C) in a controlled chamber and it is applied in sports medicine to improve recovery from musculoskeletal trauma. The aim of this study is to better define the beneficial effect of WCB on the musculoskeletal system of athletes, in particular on bone remodelling. Remodelling osteoimmunological biomarkers OPG, RANKL and RANK were measured after WBC treatment in 10 male rugby players randomly selected from the Italian National team. OPG levels were increased significantly, supporting the view that WBC induces an osteogenic effect. Further studies evaluating the effect of WBC on bone metabolism are desirable. PMID:23000054

  18. Effect of different doses of aerobic exercise on total white blood cell (WBC and WBC subfraction number in postmenopausal women: results from DREW.

    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.

  20. 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.

  3. 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

    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.

  8. A methodology to develop computational phantoms with adjustable posture for WBC calibration

    International Nuclear Information System (INIS)

    A Whole Body Counter (WBC) is a facility to routinely assess the internal contamination of exposed workers, especially in the case of radiation release accidents. The calibration of the counting device is usually done by using anthropomorphic physical phantoms representing the human body. Due to such a challenge of constructing representative physical phantoms a virtual calibration has been introduced. The use of computational phantoms and the Monte Carlo method to simulate radiation transport have been demonstrated to be a worthy alternative. In this study we introduce a methodology developed for the creation of realistic computational voxel phantoms with adjustable posture for WBC calibration. The methodology makes use of different software packages to enable the creation and modification of computational voxel phantoms. This allows voxel phantoms to be developed on demand for the calibration of different WBC configurations. This in turn helps to study the major source of uncertainty associated with the in vivo measurement routine which is the difference between the calibration phantoms and the real persons being counted. The use of realistic computational phantoms also helps the optimization of the counting measurement. Open source codes such as MakeHuman and Blender software packages have been used for the creation and modelling of 3D humanoid characters based on polygonal mesh surfaces. Also, a home-made software was developed whose goal is to convert the binary 3D voxel grid into a MCNPX input file. This paper summarizes the development of a library of phantoms of the human body that uses two basic phantoms called MaMP and FeMP (Male and Female Mesh Phantoms) to create a set of male and female phantoms that vary both in height and in weight. Two sets of MaMP and FeMP phantoms were developed and used for efficiency calibration of two different WBC set-ups: the Doel NPP WBC laboratory and AGM laboratory of SCK-CEN in Mol, Belgium. (paper)

  10. CT and 99mTc-WBC vs colonoscopy in the evaluation of inflammation and complications of inflammatory bowel diseases

    International Nuclear Information System (INIS)

    The goal of this study was to evaluate the accuracy of computerized tomography (CT) and 99mTc-white blood cell (WBC) scintigraphy versus colonoscopy in assessing inflammatory bowel diseases (IBD) in a large population of children. In a patient population of 313 consecutive children who had a 99mTc-WBC scan, 106 colonoscopies were done within a median time interval of 8 days of the 99mTc-WBC scan. One hundred and three CT scans were performed on 84 patients. Of the 42 CT scans obtained within a short time interval after the 99mTc-WBC scan, 21 (50%) were normal. In the 21 children with a positive 99mTc-WBC scan, 62% (13/21) of the CT scans underestimated the bowel wall inflammation in at least one segment. In the children with a negative 99mTc-WBC study, there were 17 negative CT examinations and 4 examinations showing an abnormal terminal ileum. When CT was compared with colonoscopy in assessing inflammation, there were five true-negative CT, two true-positive CT, no false-positive, and seven false-negative CT examinations. When 99mTc-WBC scintigraphy was compared with colonoscopy in assessing inflammation, there were seven true-positive, two false-negative, five true-negative, and no false-positive 99Tc-WBC studies. The 99mTc-WBC scan was positive in five patients with a false-negative CT examination. Of the total 103 CT scans obtained, 53 (51%) were normal. Four abscesses (3.8%) were demonstrated by CT. 99mTc-WBC scintigraphy is more sensitive than CT for detecting inflammation of the bowel wall. The incidence of complications from IBD in this retrospective study was much lower than had been previously reported. (author)

    Full Text Available Acupuncture as a vital component of traditional medical systems of the Far East has been used to restore and maintain health for over three millennia. However, the neurobiological correlates of this therapy remain largely unknown. The purpose of this study was therefore to determine the effect of enpishin acupuncture (press tack needles (PTN on autonomic function, WBC count, and oxidative stress between subjects that received either verum or placebo PTN treatment. Twenty men (mean(SD age: 36.7(5.1 years who provided oral consent were randomized to receive either verum PTN (n = 9 or placebo PTN (n = 11. Bi-Digital O-Ring Test (BDORT was used to select the acupoints for each participant. Autonomic function and oxidative stress level were analyzed before and after the treatment via heart rate variability (HRV and free radical analysis system (FRAS4, respectively. Pre- and post-treatment WBC count was also evaluated. Verum PTN group had a statistically significant increase (p = 0.008 in Ln TP, an index of overall autonomic activity. Subjects in this group also had a significantly greater (p = 0.006 variation in Ln TP than the placebo PTN group in response to the treatment. Similarly, Ln HF of subjects receiving verum PTN showed a marked increase (p = 0.0026 after the treatment. Moreover, a significantly greater (p < 0.001 variation in mean Ln HF before and after the treatment was noted in the verum group than the placebo group, reflecting a greater parasympathetic activation in the former. In contrast, sympathetic activity was not significantly influenced by verum PTN based on the lack of observed changes in LF/HF ratio. In addition, both groups failed to demonstrate significant variations in pre- and post-treatment mean Ln LF/HF ratio. Further, no significant intergroup difference was found with regard to mean variation in Ln LF/HF ratio. Verum PTN did not induce significant changes in WBC count and markers of oxidative stress, namely reactive

    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.

    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

    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.

    In the European countries renewable and decentralised electric power generation is continuously gaining in importance. More than one half of the total worldwide installed capacity of wind power plants is located in Europe. Furthermore the electric power generation of small hydro power plants and biomass fired cogeneration plants increases steadily, not least encouraged by legislation. However, especially during off-peak load conditions, a high penetration by decentralised electric power generation can cause significant problems for a stable power system operation and establishes new responsibilities for system operators. A EU-Project has been initiated to investigate the development of renewable energy sources especially for the Western Balkan Countries (WBC), including an analysis of the impact on the grid. The effects of decentralised electric power generation on the grid of the WBC are analysed, aiming for the development of a general methodology to identify critical system configurations. The limits of the feed-in into the existing transmission and distribution systems of decentralised power generation units, not taking part in power system control services, are analysed for steady state conditions. Together with matching approaches of the other project partners, corresponding problems can be addressed already within the planning phase. (author)

  4. A low energy germanium detector system for lung counting at the WBC facility of CIEMAT

    International Nuclear Information System (INIS)

    The lung deposition of actinides is a critical radiation protection problem in places dealing with these materials. The Internal Dosimetry Group of CIEMAT counts with four Canberra low energy germanium detectors (LEGe) to perform in vivo lung measurements of radionuclides incorporated in the human body, being efficient for an energy range from 10 to 1000 keV. Each detector is 70 mm in diameter and is equipped with a carbon epoxy window. A great improvement is achieved after the substitution of the old phoswich detectors by the Ge system in the detection of X rays and low energy gamma radiation. The LEGe system is calibrated using the LLNL phantom with a pair of lungs containing homogeneously distributed 241Am and 152Eu, and a set of five overlay plates covering a chest wall thickness range from 1.67 to 4.27 cm. As an application of the LEGe system in the in vivo measurements of actinides, a routine monitoring programme is designed for workers involved in nuclear fuel fabrication processes to detect 238U (234Th) and 235U in the lungs. The reality of radiation exposures in Spain includes planning the decommissioning of nuclear power plants and redundant old nuclear facilities; special monitoring programmes are performed for the detection of 241Am in workers associated with decontamination and dismantling procedures. As a result of the aviation accident that took place over the Palomares space in 1967, members of the public living in the area were, and continue to be, potentially exposed to 239Pu and 241Am by inhalation. The excellent resolution and good sensitivity of the LEGe detector system provides a more accurate assessment of intake and dose in cases of internal contamination by all these radionuclides, emitting at low and moderate energies.

    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)

    Forty-nine children with Kawasaki disease were included in this study. Based on the severity of carditis as determined by Tc-99m HMPAO-labeled WBC heart scan, the children were separated into two groups. Group A (n=24) had significant carditis and group B (n=25) did not have significant carditis. The left and right ventricular ejection fractions (LVEF and RVEF) were evaluated by equilibrium multigated blood pooling ventriculography. Diameters of the left and right coronary arteries (LCA and RCA) were measured by two-dimensional echocardiography. The results showed that group A had lower LVEF and RVEF, but larger diameters of the LCA and RCA than those of group B patients. The sensitivity of significant carditis to predict left ventricular dysfunction, right ventricular dysfunction, LCA dilation and RCA dilation was 88.9, 70.6, 75, and 71.4%, respectively; the specificities were 100, 100, 100, and 67.9%, respectively. Our findings suggest that significant carditis determined by Tc-99m HMPAO-labeled WBC heart scan can accurately predict impaired ventricular function and coronary artery dilation. PMID:14602219

  9. MaMP and FeMP: computational mesh phantoms applied for studying the variation of WBC efficiency using a NaI(Tl) detector

    International Nuclear Information System (INIS)

    In a previous study, the counting efficiency calibration was calculated for 36 computational mesh phantoms called MaMP and FeMP—Male and Female Mesh Phantoms, which span variations in height, weight and gender. They were created to be used in a sitting configuration WBC set-up using an HPGe detector. Now this work is extended to investigate the influence of body sizes and the position of the detector on the counting efficiency (CE) for a different counting geometry. This was done by creating a new set of MaMP and FeMP mesh phantoms lying on a reclining chair and by studying the variation of the counting efficiency using a NaI(Tl) detector for the WBC set-up of SCK-CEN. The deviation of the CE due to the detector’s position with respect to the phantom was investigated. Correlations were also studied for CE as a function of trunk volume, waist–hips ratio (WHR) and waist–chest ratio (WCR) for different mesh phantoms. (paper)

  10. 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.

  20. 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

  10. Applications of nuclear technologies for in-vivo elemental analysis

    International Nuclear Information System (INIS)

    Measurement facilities developed, to date, include a unique whole-body-counter, (WBC); a total-body neutron-activation facility (TBNAA); and a partial-body activation facility (PBNAA). A variation of the prompt-gamma neutron-activation technique for measuring total-body nitrogen was developed to study body composition of cancer patients and the effect of nutritional regimens on the composition. These new techniques provide data in numerous clinical studies not previously amenable to investigation. The development and perfection of these techniques provide unique applications of radiation and radioisotopes to the early diagnosis of certain diseases and the evaluation of therapeutic programs. The PBNAA technique has been developed and calibrated for in-vivo measurement of metals. Development has gone forward on prompt-gamma neutron activation for the measurement of cadmium, x-ray fluorescence (XRF) for measurement of iron. Other techniques are being investigated for in-vivo measurement of metals such as silicon and beryllium

    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 The rapid growth in microelectronics and crunching RISC in the field of bio-medical sciences incorporated of soft tools to diagnose various parameters of human fluids. Conventional method of blood sample analysis makes use of laboratory technique of titration, which is operator-dependent and results in lot of errors depending on the skill of the technician. In order to eliminate the human errors involved in the conventional method, in this paper an attempt has been made to present a capillary centrifuge technique driven by high speed DC motor fed by Morgan chopper and controlled by powerful ARM processor. It results in accurate analysis of the blood samples. The various techniques involved in accurate sensing of speed using timer and generation of firing pulses to thyristor in the Morgan chopper is judiciously achieved. This paper clearly brings out the advantages of the proposed blood measurement technique which effectively gives blood analysis faster and at a low cost.

    The production of iodine isotopes in nuclear reactors and cyclotrons as well as the use and handling of non-sealed liquid sources of iodine in nuclear medicine services for diagnosis and treatment represent a significant risk of internal contamination for the professional staff. Iodine is metabolized after ingestion or inhalation and tends to deposit preferentially in the thyroid tissue. Individual monitoring in these cases can be carried out through in vivo bioassay techniques. To calibrate the detection systems for the iodine isotopes, anthropomorphic phantoms of neck and thyroid containing known amounts of 123I, 125I and 131I were developed. The IRD-CNEN Whole Body Counter uses a NaI(Tl)3X3 detector for 131I measurements and a HPGe module with two crystals, for the measurement of the isotopes 123 and 125. The NaI(Tl) detector operates in the energy range from 30 to 3000 keV and the HPGe system from 10 to 200 keV. The choice of the detection system to be used in the measurement is based on the photon energy emitted by each radionuclide. The thyroid phantom for the calibration of 123I uses 139Ce, which emits photons with energies very close to 123I but with a longer half-life (137 days). For the calibration of 125I, the same isotope was used since it presents a suitable half-life to perform the measurements (60 days). For the development of the 131I thyroid phantom, the same isotope 131 was used as the standard. All the calculated calibration factors obtained by this technique were compared with the factors obtained using the Visual Monte Carlo in vivo program that simulates mathematically the contamination and counting conditions and geometry. The results obtained by these two methods are in good agreement. (Author)

  19. 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.

    Superconductivity has found many attractive applications in medicine, science, power systems, engineering, transport and electronics. One of the most prominent applications of superconductivity are superconducting magnets e.g. MRI magnets, NMR magnets, accelerator magnets, and magnets for fusion; most applications still use low temperature superconductors. Since the discovery of high temperature superconductivity (HTS) in 1986 there has been a tremendous progress in R&D of HTS material, wires and applications. Especially for power system applications, HTS offers considerable economic benefits. Many HTS demonstrator or prototype applications have been built and successfully tested, and some HTS applications like cables and superconducting fault current limiters seem very close to commercialisation. This paper gives an overview about the present and future HTS applications in power applications, high field magnets and current leads.

    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

  2. Role of 99m TC HMPAO WBC scan in the localization of infection in patients with orthopedic implants

    International Nuclear Information System (INIS)

    Objectives: Patients presenting with pain after implantation of orthopedic devices pose major diagnostic problem with regards to loosening vs. infection. Three phase bone scan is less specific technique in this regard.99mTcHMPAO labeled leukocyte accumulation has been observed not only in the sites of skeletal infection but also in the soft tissue infection sites as well. We undertook a study to assess the role of 99m HMPAO labeled leukocyte scan in this context. Method: Totally 27 patients suspected of infection were subjected to 99mTc HMPAO leukocyte scan. Whole body and spot images of the region of interest were acquired at 30 minutes and 3 hours after the injection 555 MBq 99mTc labeled leucocytes. The focal area of abnormal accumulation of leucocytes was considered as infection while the mild and diffuse uptake pattern was considered in favor of inflammation. The scan findings were compared with surgery, cytopathological (13), bacteriological (9) and clinical follow-up up to 1 year. Results: Of the 27 patients who underwent leukocyte scan 19 patients showed evidence of infection on the scan. There were totally 33 foci of infection of which 31 were found to be true positive while two were false positive for infection. In the true positive group 25 foci were confined to the implants region while 7 foci were found to be in the soft tissue compartment. One focus was involving both osseous and non-osseous region. One false negative patient was found to have chronic osteomyelitis on surgery. All these findings were well correlated with surgical, cytopathological and the follow-up data. The overall sensitivity of the technique for both osseous and non-osseous lesion was 96% and specificity 82% with a positive predictive value of 94%. Conclusion: We conclude that 99mTc HMPAO leukocyte scan is a sensitive and specific tool for the detection and localization of the infection in osseous and non- osseous sites in patients with orthopedic devices

    Whole-body cryotherapy (WBC) involves short exposures to air temperatures below -100°C. WBC is increasingly accessible to athletes, and is purported to enhance recovery after exercise and facilitate rehabilitation postinjury. Our objective was to review the efficacy and effectiveness of WBC using empirical evidence from controlled trials. We found ten relevant reports; the majority were based on small numbers of active athletes aged less than 35 years. Although WBC produces a large temperature gradient for tissue cooling, the relatively poor thermal conductivity of air prevents significant subcutaneous and core body cooling. There is weak evidence from controlled studies that WBC enhances antioxidant capacity and parasympathetic reactivation, and alters inflammatory pathways relevant to sports recovery. A series of small randomized studies found WBC offers improvements in subjective recovery and muscle soreness following metabolic or mechanical overload, but little benefit towards functional recovery. There is evidence from one study only that WBC may assist rehabilitation for adhesive capsulitis of the shoulder. There were no adverse events associated with WBC; however, studies did not seem to undertake active surveillance of predefined adverse events. Until further research is available, athletes should remain cognizant that less expensive modes of cryotherapy, such as local ice-pack application or cold-water immersion, offer comparable physiological and clinical effects to WBC.

    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.

    Whole-body cryotherapy (WBC) is an increasing applied cryotherapeutic method, that involves application of a cryotherapeutic factor to stimulate the body by the means of intense hypothermia of virtually the body's entire area. This method is still not well recognized in Western Europe. However in recent years it is becoming increasingly popular in sports medicine and also in clinical application. Cryotherapeutic agents used in WBC are considered to be a strong stress stimulus which is associated with a variety of changes in functional parameters, particularly of the cardiovascular and autonomic nervous systems. However, such strong influence upon the entire body could be associated with the risk of unexpected reactions which might be dangerous for homeostasis. The present study evaluated the complex hemodynamic physiological reactions in response to WBC exposure in healthy subjects. Thirty healthy male volunteers participated. Each subject was exposed to WBC (-120°C) for 3-min. None of the participants had been exposed to such conditions previously. The research was conducted with modern and reliable measurements techniques, which assessed complex hemodynamic reactions and skin temperature changes non-invasively. All measurements were performed four times (before WBC, after WBC, WBC+3h and WBC+6h) with a Task Force Monitor (TFM - CNSystems, Medizintechnik, Gratz, Austria). Body superficial temperature was measured by infrared thermographic techniques - infra-red camera Flir P640 (Flir Systems Inc., Sweden). Our results show a significant decrease in heart rate, cardiac output, and increase in stroke volume, total peripheral resistance and baroreceptors reflex sensitivity. These changes were observed just after WBC exposure. At stages WBC+3h and WBC+6h there was observed a significant drop in baroreceptors reflex sensitivity due to increased thermogenesis. In conclusion, the present findings suggest that WBC strongly stimulates the baroreceptor cardiac reflex in

    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

  18. The role of 99mTc-labelled stannous colloid white blood cells scanning in the evaluation of and differentiation between cellulitis and osteomyelitis

    International Nuclear Information System (INIS)

    Full text: Sequential 99mTc-MDP and 67Ga-citrate scanning have been extensively used in the evaluation of infection. 99mTc-labelled stannous colloid white blood cell (Tc-WBC) is not widely reported. A prospective study was undertaken in 92 patients to assess Tc-WBC and Tc-MDP scanning in this clinical application. Labelling efficiency (LE) was calculated with a mean ± SD of 94 ± 4.8 %. Patients (6) who were treated with gentamycin had an LE ± SD of 70 ± 9%. Twenty six patients treated as osteomyelitis had congruent abnormalities on Tc-WBC and Tc-MDP scans. Twenty one patients treated as cellulitis had abnormalities demonstrated on Tc-WBC but not on Tc-MDP scans. Tc-WBC appeared to define areas of inflammation of bone and soft-tissue in the hands or feet more distinctly than Tc-MDP. Fourteen patients had progress Tc-WBC scans 4-6 weeks following antibiotic treatment. Changes in scan appearances seemed to mirror the clinical course of the patients. Tc-WBC and Tc-MDP scans were useful complementary studies in the diagnosis, evaluation and assessment of treatment in patients with cellulitis and osteomyelitis

WBC is increasingly accessible to athletes, and is purported to enhance recovery after exercise and facilitate rehabilitation postinjury. Our objective was to review the efficacy and effectiveness of WBC using empirical evidence from controlled trials. We found ten relevant reports; the majority were based on small numbers of active athletes aged less than 35 years. Although WBC produces a large temperature gradient for tissue cooling, the relatively poor thermal conductivity of air prevents significant subcutaneous and core body cooling. There is weak evidence from controlled studies that WBC enhances antioxidant capacity and parasympathetic reactivation, and alters inflammatory pathways relevant to sports recovery. A series of small randomized studies found WBC offers improvements in subjective recovery and muscle soreness following metabolic or mechanical overload, but little benefit towards functional recovery. There is evidence from one study only that WBC may assist rehabilitation for adhesive capsulitis of the shoulder. There were no adverse events associated with WBC; however, studies did not seem to undertake active surveillance of predefined adverse events. Until further research is available, athletes should remain cognizant that less expensive modes of cryotherapy, such as local ice-pack application or cold-water immersion, offer comparable

    1986-01-01

    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.

    Hochstadt, Jake

    2011-01-01

    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.

    Optical coherence tomography (OCT), as an interferometric method, has been studied as a distance ranger. As a technology capable of producing high-resolution, depth-resolved images of biological tissue, OCT had been widely used for the application of ophthalmology and has been commercialized in the market today. Enlightened by the emerging research interest in biomedical domain, the applications of OCT in industrial inspection were rejuvenated by a few groups to explore its potential for characterizing new materials, imaging or inspecting industrial parts as a service solution[3]. Benefiting from novel photonics components and devices, the industrial application of the older concepts in OCT can be re-visited with respect to the unique performance and availability. Commercial OCT developers such as Michelson Diagnostics (MDL; Orpington, U.K.) and Thorlabs (Newton, NJ) are actively exploring the application of OCT to industrial applications and they have outlined meaningful path toward the metrology application in emerging industry[3]. In this chapter, we will introduce the fundamental concepts of OCT and discuss its current and potential industrial applications.

    International Nuclear Information System (INIS)

    Objective: To evaluate partial splenic embolization (PSE) with trisacryl gelatin microsphere in treating secondary hypersplenism. Methods: Thirty patients with hypersplenism were treated with PSE. The patients were randomly divided into two groups. Trisacryl gelatin microsphere used as the embolic material was employed in study group (n = 14), while Gelfoam was employed in control group(n = 16). The occlusive area was controlled within 50% to 80%. All patients were followed up for six months. After the PSE procedure the peripheral white blood cell (WBC) count and the platelet (PLT) count were determined, and the adverse reaction was observed. Results: Six months after the treatment, both WBC and PLT counts fell to normal in 28 patients, and recurrence was seen in two patients of control group. No significant difference in clinical therapeutic results existed between two groups. However, the abdominal pain in the patients of study group was obviously mild and lasted shorter than that in the patients of control group. In performing the embolization procedure, the embolic agent trisacryl gelatin microsphere was easily to be managed. Conclusion: Used as an embolic agent in partial splenic embolization for secondary hypersplenism, trisacryl gelatin microsphere is effective and safe, moreover, it is easy to be operated with fewer postoperative side effects.

Supercritical fluids have been applied to mass-transfer processes, phase-transition processes, reactive systems, materials-related processes, and nanostructured materials. Some applications are already at industrial capacity, whereas others remain under development. In addition to extraction, application areas include impregnation and cleaning, multistage countercurrent separation, particle formation, coating, and reactive systems such as hydrogenation, biomass gasification, and supercritical water oxidation. Polymers are modified with supercritical fluids, and colloids and emulsions as well as nanostructured materials exhibit interesting phenomena when in contact with supercritical fluids that can be industrially exploited. For these applications to succeed, the properties of supercritical fluids in combination with the materials processed must be clearly determined and fundamental knowledge of the complex behavior must be made readily available.

    Hochstadt, Jake

    2011-01-01

    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.

  20. Applications of radioluminescent lighting

    International Nuclear Information System (INIS)

    Glass-tube radioluminescent (RL) systems have been demonstrated as attractive alternatives to electrically powered airfield marking and lighting systems for remote airfields, rapid runway repair, and other airfield lighting and marking uses. Individual light units for RL systems are self-powered, reliable, easily maintained and deployed, and can be made to produce infrared or visible light. Tests and demonstrations of prototype light units conducted by the US Dept. of Energy's RL Lights Program in recent years for the Air Force, Navy, Army, and Marine Corps and for Florida and Alaska have proved the basic technological worth of RL airfield lighting systems for civilian and military use. The technology has advanced to a point where other military and civilian applications can now be considered. Military applications include emergency degree, damage control, cargo marking, low-level lighting for work areas and other unique uses. Civilian applications include marine navigational aids, roadway marking, emergency escape lighting, lighting for telephone conduit tunnels, and other applications where access to electrical power is limited or difficult to supply or maintain. Isotope options for these applications are shown. Research is expected to produced advanced RL light systems within the next several years

    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.

    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.

    Fischer, N; Tarasow, T; Tok, J

    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.

  16. Medical applications of holography

    Science.gov (United States)

    von Bally, Gert

    1991-11-01

    From the various capabilities of holography for image processing and measuring purposes, holographic interferometric techniques have found more extended application in biological and medical research. Due to their special properties the different methods of holographic interferometry are applied to characteristic fields of biomedical investigations where--similar to nondestructive testing--vibration and deformation analysis is of interest. Features of holographic interferometry, such as the possibility of noncontactive, three-dimensional investigations with a large field-of-depth, are used with advantage. The main applications can be found in basic research e.g., in audiology, dentistry, opthalmology, and experimental orthopedics. Because of the great number of investigations and the variety of medical domains in which these investigations were performed this survey is confined to some characteristic examples. As in all fields of optics and laser metrology, a review on biomedical applications of holography would be incomplete if military developments and utilization were not mentioned. As demonstrated by selected examples, the increasing interlacing of science with the military does not stop at domains that traditionally are regarded as exclusively oriented to human welfare--like biomedical research. The term ''Star Wars Medicine'', which becomes an increasingly popular expression for laser applications (including holography) in medicine, characterizes the consequences of this development.

    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.

    2009-12-01

    Full Text Available Abstract Background Sequence similarity searching is a very important bioinformatics task. While Basic Local Alignment Search Tool (BLAST outperforms exact methods through its use of heuristics, the speed of the current BLAST software is suboptimal for very long queries or database sequences. There are also some shortcomings in the user-interface of the current command-line applications. Results We describe features and improvements of rewritten BLAST software and introduce new command-line applications. Long query sequences are broken into chunks for processing, in some cases leading to dramatically shorter run times. For long database sequences, it is possible to retrieve only the relevant parts of the sequence, reducing CPU time and memory usage for searches of short queries against databases of contigs or chromosomes. The program can now retrieve masking information for database sequences from the BLAST databases. A new modular software library can now access subject sequence data from arbitrary data sources. We introduce several new features, including strategy files that allow a user to save and reuse their favorite set of options. The strategy files can be uploaded to and downloaded from the NCBI BLAST web site. Conclusion The new BLAST command-line applications, compared to the current BLAST tools, demonstrate substantial speed improvements for long queries as well as chromosome length database sequences. We have also improved the user interface of the command-line applications.

    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).

  2. Magnetoplasmadynamic thruster applications

    International Nuclear Information System (INIS)

    Advance study activities within NASA indicate that electric propulsion will be required to make certain types of potential missions feasible. The large power levels under consideration make magnetoplasmadynamic thrusters a good candidate for these applications since this type of electric thruster is best suited to operation at high power levels. The status of the magnetoplasmadynamic thruster is examined and compared to the ion thruster which also is a candidate. The use of these two types of electric propulsion devices for orbit raising of a self-powered large satellite is examined from a cost standpoint. In addition the use of nuclear electric propulsion is described for use as both a near-earth space tug and for an interplanetary exploration vehicle. These preliminary examinations indicate that the magnetoplasmadynamic thruster is the lowest cost thruster and therefore merits serious consideration for these applications

  3. Cogeneration and trigeneration applications

    International Nuclear Information System (INIS)

    Combined heat and power cogeneration, or ''autoproduction'' as it is known in Turkey, is the simultaneous production of heat and electricity, while trigeneration includes the cold production in addition to cogeneration. This technology has been advanced by governmental support and the continuing need for additional electricity generation within Turkey. The present study deals with cogeneration and trigeneration applications in Turkey, giving the electricity market development. Only four cogeneration plants with a total capacity of 30 MW e were operated up to 1994, while trigeneration applications have started for the last two years. The total installed cogeneration capacity is expected to reach up to 6,000 MWe by 2005, which would represent about 20% of Turkey's total installed electricity generating capacity. In this context, cogeneration and trigeneration have had, or will have, a significant and increasing role in dictating the energy strategies for Turkey. (Author)

Wire strength has improved and large prototypes fabricated or under consideration using HTS include Superconducting Magnetic Energy Storage (SMES), rotating electrical machines including synchronous ac and dc homopolar motors and drives, generators and condensers, underground transmission cables, utility distribution equipment such as transformers and current limiters, commercial processing applications such as magnetic separation, and specialty magnets such as high field inserts. In this paper the requirements, progress toward these requirements, and the prospects for the future are reviewed

  8. Metagraphs and their applications

    CERN Document Server

    Basu, Amit

    2007-01-01

    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...

  11. Justification: theory and application

    International Nuclear Information System (INIS)

    The concept of justification implies that a specific decision as to the relative merits of benefits and costs and detriment be made whenever: (1) a new practice is introduced that involves an indirect or direct increase in radiation exposure; or (2) an existing practice affecting radiation exposure is modified; or (3) an increase in radiation protection of an existing practice is to be considered. Such decisions are imprecise and involve intangible values. ICRP has, however, developed a mathematical model to express the structure of such decisions. The utility of this model for making the key paramters of justification decisions visible is explored in this paper in two ways. First, the structure of the model and its implications are explored in the abstract. Secondly, several specific applications are studied to determine if the model has utility in structuring application decisions, and the extent to which conclusions can be evolved in a meaningful, visible manner.

  12. Applications of optical imaging

    International Nuclear Information System (INIS)

    Optical imaging in the form of near infrared fluorescence and bioluminescence has proven useful for a wide range of applications in the field of molecular imaging. Both techniques provide a high sensitivity (in the nanomolar range), which is of particular importance for molecular imaging. Imaging with near infrared fluorescence is especially cost-effective and can be performed, in contrast to radioactivity-based methods, with fluorescence dyes that remain stable for months. The most important advantage of bioluminescence, in turn, is the lack of background signal. Although molecular imaging with these techniques is still in the experimental phase, an application of near infrared fluorescence is already foreseeable for the imaging of superficial structures.

    Bucur, Claudia

    2016-01-01

    Working in the fractional Laplace framework, this book provides models and theorems related to nonlocal diffusion phenomena. In addition to a simple probabilistic interpretation, some applications to water waves, crystal dislocations, nonlocal phase transitions, nonlocal minimal surfaces and Schrödinger equations are given. Furthermore, an example of an s-harmonic function, its harmonic extension and some insight into a fractional version of a classical conjecture due to De Giorgi are presented. Although the aim is primarily to gather some introductory material concerning applications of the fractional Laplacian, some of the proofs and results are new. The work is entirely self-contained, and readers who wish to pursue related subjects of interest are invited to consult the rich bibliography for guidance.

    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.

A simple design lamp having forced cooling and an excitation generator was demonstrated to have a lifetime of more than one thousand hours. The results of an experimental study of capacitive and high voltage nanosecond discharge-driven excilamps are presented. The influence of the excitation regime and operating gas mixture pressure on the dielectric barrier discharge (DBD) driven excilamps' efficiency is discussed. The discharge formation and output radiation dynamics of DBD driven excilamps was experimentally studied for the first time. The practical applications of several lamps designed in the High Current Electronics Institute, Tomsk, Russia to photochemistry, photobiology and photomedicine are discussed.

  16. Diverse applications of radioimmunoassay

    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.)

    Full Text Available This paper deals with the issue of a long time research concerning the representation of complex surfaces in descriptive geometry. The ability to use the different techniques of representation aims to achieve results never thought before. In the University of Palermo, at the Engineering School, the research involved the study on simplifying a more elaborated way to represent the geometry and its applications in buildings architecture and related engineering plants and equipment. Specifically, is here reported the application of the proposed method to represent one of the most used surfaces in the buildings design. It concerns a helicoid surface represented in orthogonal axonometric projecting. The method is essentially based on the experimental homology that, by the way, is extensively documented in the bibliography section of this paper.

    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.

    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.

    International Nuclear Information System (INIS)

    Nano technology is the engineering of functional systems at the molecular scale. This covers both works and concepts that are more advanced. In its original sense, nano technology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete high performance products. Development of applications incorporating semiconductor nanoparticles to be used in the next generation of products, such as display technology, lighting, solar cells and biological imaging and others are widely progressives. Progress has been made in using medical applications (Nano medicine) which provided the possibility of delivering drugs to specific cells using nanoparticles. Otherwise, nanoparticles have high surface area to volume ratio, allowing many functional groups to be attached to a nanoparticle, which can seek out and bind to certain tumor cells (cancer).

  7. 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

  8. Nuclear applications for health

    International Nuclear Information System (INIS)

    Just before the turn of the 20th century, the discoveries of X-rays, in 1895, and of radioactivity, in 1896, opened up whole new worlds of science. For the medical community, the world has been changing ever since, in some countries far more rapidly than in others. Over the past 100 years, the X-ray has become as familiar to most people as the dentist's chair. As we move into the next century, greater attention is being placed upon less known but more far-reaching radiation technologies and nuclear applications that today's physicians are able to use for earlier diagnosis and treatment of serious illness. This article, in question-and-answer format, explains the differences between the various types of nuclear applications for human health and looks at the evolution of the IAEA's related activities.

  10. 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.

  11. 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...

    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.

    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)

  17. 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

  18. Load Balancing Scientific Applications

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    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.

  19. Stable isotope applications

    International Nuclear Information System (INIS)

    The following domains of stable isotope applications are presented: - isotope dilution analyses as in trace analyses or volume and mass determinations; - stable isotopes as tracers as applied in environmental studies, agricultural research, products and objects authentification, transport phenomena, reaction mechanisms, determinations of structure and complex biological function, metabolism studies, diagnostic respiration tests, positron emission tomography; - equilibrium isotopic effects as investigated in measurements of effects, studies of equilibrium conditions, the mechanism of drug action, study of natural processes, water circuit, temperature measurements; - kinetic isotopic effects, as, for instance, reaction rates and mechanisms, solvent isotopic effects; - stable isotopes for advanced nuclear reactors as, for instance, uranium nitride with 15 N as nuclear fuel or 157 Gd for reactivity control. In spite of the difficulties regarding stable isotope use and first of all, of the difficult and costly analytical techniques, a continuous growth of the number of stable isotope applications in different fields is registered. The number of works and scientific meetings on the subject, as organized by the International Society of Isotopes and IAEA-Vienna, Gordon Conferences, regional meetings in Germany, France, etc. increase continuously. Development of the stable isotope application on a larger scale requires improving both their production technologies as well as those of labelled substances and, at the same time, the analytical methods

  20. Therapeutic applications of radiopharmaceuticals

    International Nuclear Information System (INIS)

    Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

    Katipamula, Srinivas; Lutes, Robert G.; Ngo, Hung; Underhill, Ronald M.

    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.

    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.

  8. 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). The WAP (Wireless Application Protocol) Forum was founded in 1997 to create a global protocol

  19. Monte Carlo technique applications in the field of radiation dosimetry at the ENEA Radiation Protection Institute: A review

    International Nuclear Information System (INIS)

    At the ENEA (Ente Nazionale per le Nuove Technologie l'Energia e l'Ambiente) Institute of Bologna (Italy) many years of various activities have been carried out in the field of experimental dosimetry and radiation protection. As far as the external radiation monitoring is concerned, these activities dealt with the design, development and type test of photon personal dosemeters as well as routine reading and control of dosemeters, calibration activities etc. As far as the internal dosimetry activities are concerned a whole body counter (WBC) has been built and used many years both for research activities and for routine assessment of internal doses. The WBC has been extensively used in the recent years, especially after the Chernobyl accident, to assess doses from intake of radioactive nuclides for Italian workers employed in Russia as well as normal population mainly living in the north-eastern Italian areas. In recent years, the necessity of improving the general dose assessment capabilities and to provide accurate field parameters and operational quantities, according to the international recommendations, outlined the importance of coupling experimental work with Monte Carlo radiation transport modelling. The present paper summarizes some studies carried out with Monte Carlo in the framework of the ENEA contribution to the activities of the EURADOS Working Group 4; they are concerned with computations of field parameters and operational quantities for the ICRU sphere with reference photon beams and modelling and calculations for photon internal and external dose assessment with the ADAM anthropomorphic phantom

  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

    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. PMID:26678028

  6. Factsheets Web Application

    Energy Technology Data Exchange (ETDEWEB)

    VIGIL,FRANK; REEDER,ROXANA G.

    2000-10-30

    The Factsheets web application was conceived out of the requirement to create, update, publish, and maintain a web site with dynamic research and development (R and D) content. Before creating the site, a requirements discovery process was done in order to accurately capture the purpose and functionality of the site. One of the high priority requirements for the site would be that no specialized training in web page authoring would be necessary. All functions of uploading, creation, and editing of factsheets needed to be accomplished by entering data directly into web form screens generated by the application. Another important requirement of the site was to allow for access to the factsheet web pages and data via the internal Sandia Restricted Network and Sandia Open Network based on the status of the input data. Important to the owners of the web site would be to allow the published factsheets to be accessible to all personnel within the department whether or not the sheets had completed the formal Review and Approval (R and A) process. Once the factsheets had gone through the formal review and approval process, they could then be published both internally and externally based on their individual publication status. An extended requirement and feature of the site would be to provide a keyword search capability to search through the factsheets. Also, since the site currently resides on both the internal and external networks, it would need to be registered with the Sandia search engines in order to allow access to the content of the site by the search engines.

  7. Industrial applications of radiations

    International Nuclear Information System (INIS)

    Radiation processing refers to the use of ionizing radiation to initiate chemical or biological changes in various materials as a substitute for conventional thermal or chemical processes. The method was inroduced in the industrial field 30 years ago and is now being widely used for numerous applications, among which industrial radiography, polymer modification, sterilization or decontamination, and food preservation. Both electron beam accelerators and gamma sources can be used, depending mainly of the amount of radiation and the penetration required. Radiation processing presents an increasing economical importance; in 1986 the market volume of ionized products ranged 3 billion $

Based on trends on HTTP Archive, deployed JavaScript code size has grown 45% over the course of the year. MVC offers architectural benefits over standard JavaScript — it helps you write better organized, and therefore more maintainable code. This pattern has been used and extensively tested over multiple languages and generations of programmers. It's no coincidence that many of the most popular web programming frameworks also encapsulate MVC principles: Django, Ruby on Rails, CakePHP, Struts, or Laravell.

  13. Whole-body cryotherapy in athletes.

    Science.gov (United States)

    Banfi, Giuseppe; Lombardi, Giovanni; Colombini, Alessandra; Melegati, Gianluca

    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).

    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.

    2010-01-01

    The ability to introduce foreign DNA into the genome of an organism has proven to be one of the most powerful tools in modern biology. Methods for the manipulation of the animal genome have been developed at an impressive pace for 3 decades, but only in the past 5 years have useful tools for avian transgenesis emerged. The most efficient technique involves the use of replication-deficient lentiviral vectors to deliver foreign DNA into the avian germline. Although lentiviral-mediated transgenesis presents some constraints, progress in this area has garnered interest in both industry and academia for its potential applications in biological research, biotechnology, and agriculture. In this review we evaluate methods for the production of transgenic birds, focusing on the advantages and limitations of lentiviral-mediated transgenesis. We also provide an overview of future applications of this technology. The most exciting of these include disease-resistant transgenic poultry, genetically modified hens that produce therapeutic proteins in their eggs, and transgenic songbirds that serve as a model to study communication disorders. Finally, we discuss technological advances that will be necessary to make avian transgenesis a more versatile tool. PMID:21131712

    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.

  3. Nuclear applications: Future prospects

    International Nuclear Information System (INIS)

    Full text: Nuclear physics and energy research depends on and advances science and technology outside of the nuclear field. Perhaps the most commonly perceived benefits to society from nuclear and particle physics are those derived from particle beam technology. Charged particle accelerators play an increasing role in applications in industry and medicine. Neutrons produced with a high power proton accelerator in a spallation process are used from basic research, radiography in automotive industry (example fuel cell development) to transmutation of highly radioactive fission products. Production and acceleration of ultra cold neutrons provide intense and almost mono-energetic neutrons to study soft matter. Heavier radioisotopes are used in a wide field ranging from medicine to semiconductor industry (ion implantation for doping or coating technologies). Concrete examples and future trends will be given. Detailed understanding of ion physics at low energy allows the design of compact accelerator mass spectroscopy (close to table top size). The ability to measure concentrations of specific radioactive isotopes even below the natural radioactivity widens the scope of applications from archaeology, climate research to food industry. Such a compact device is close to commercialisation. (author)

    2011-05-01

    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.

    International Nuclear Information System (INIS)

    The radioisotopes are produced for various applications in the nuclear medicine (diagnostic, therapy, palliation of metastatic bone pain), industry (radiography of welds ...), agriculture (radiotracers ...) and basic research. Due to the availability of high neutron fluxes (thermal neutron flux up to 1015 n/cm2.s), the BR2 reactor is considered as a major facility through its contribution for a continuous supply of products such 99Mo (99mTc), 131I, 133Xe, 192Ir, 186Re, 153Sm, 90Y, 32P, 188W (188Re), 203Hg, 82Br, 41Ar, 125I, 177Lu, 89Sr, 60Co, 169Yb, 147Nd, and others. Neutron Transmutation Doped (NTD) silicon is produced for the semiconductor industry in the SIDONIE (Silicon Doping by Neutron Irradiation Experiment) facility, which is designed to continuously rotate and traverse the silicon through the neutron flux. These combined movements produce exceptional dopant homogeneity in batches of silicon measuring 4 and 5-inches in diameter by up to 750 mm in length. To provide a reliable and qualitative supply of radioisotopes and NTD-silicon to the customers in accordance with a quality system that has been certified to the requirements of the EN ISO 9001: 2000. This new Quality System Certificate has been obtained in December 2006 for the Production of radioisotopes for medical and industrial applications and the Production of Neutron Transmutation Doped (NTD) Silicon in the BR2 reactor

  7. Dose distributions around selectron applicators

    International Nuclear Information System (INIS)

    Measured and calculated dose distributions around selectron applicators, loaded with 60Co high dose rate pellets, are presented. The effect of the stopping screw, spacers, pellets themselves and the applicator wall on the dose distribution is discussed. The measured dose distribution is in almost perfect agreement with the calculated distribution in planes perpendicular to the applicator axis and containing a source. On the applicator axis directly below the applicator the measured dose amounts to about 75% of the calculated value, when only the stopping screw attenuates the beam from a pellet. When the beam is attenuated by spacers in addition to the stopping screw, the discrepancy between the calculated and measured dose may exceed 50%. Clinically relevant source geometries are also discussed. It is shown that for most regions around the applicator the method of a simple addition of dose contributions from individual point sources is an acceptable approximation for the calculation of dose distributions around the selectron applicators

  8. 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

  9. Dynamic Reconfiguration of Application Logic During Application Migration

    Science.gov (United States)

    Klus, Holger; Schindler, Björn; Rausch, Andreas

    During migration of an application from a source to a target device, its application logic often has to be adapted to the new situation. The new situation can for instance be characterized by different hardware resources or a different usage context . Therefore, the application logic has to be adapted automatically to the new context in order to provide the most suitable behaviour before and after migration. We consider application logic that consists of components which interact with each other through well-defined interfaces. In order to adapt the behaviour of the application logic, components can be added, removed or replaced. In this chapter we introduce a concept which enables the dynamic reconfiguration of component-based applications based on context information during the migration process. Our concept enables a technology independent specification of adaptation behaviour. Furthermore, we support the specification of an application without referencing application components directly. In that way it is possible to integrate new components into applications that were not known during application development time.

    2016-02-01

    Whole body cryotherapy (WBC) in a cryo-chamber as a medical treatment was first established in Japan in the 1980s, later in Central Europe, and is now becoming more popular also in the United States. The exposure to extreme, non-physiological environmental conditions in a cryo-chamber at -110 °C may exceed the normal adaption capacity. The aim of this study was to investigate the effects of WBC on blood pressure (BP) readings in adult subjects with rheumatic disorders and normal or moderately elevated BP. A sample of 23 subjects (8 female, 15 male) which were recruited according to their pathology between the age of 35 and 69 years undergoing 21 WBC applications was divided into three groups: a group of subjects with anti-hypertensive therapy, a group of subjects with mild arterial hypertension without medical treatment, and a normotensive control-group. A total of 483 BP readings were taken immediately before and after each WBC application. The systolic and diastolic BP were recorded, and the mean arterial pressure, and the amplitude of BP were calculated. A statistically significant rise of BP after WBC was found in the whole sample and in the normotensive group. Over the course of time, no significant change of BP behavior was observed, except for normotensive subjects, who showed a wider range in their systolic BP values. Generally accepted exclusion criteria were applied, and in our sample group WBC was safe with respect to unwanted BP alterations for adult subjects under 70 years-regardless of a pre-existing untreated mild or pharmacologically treated arterial hypertension. Greater changes of BP values might infrequently occur, so an individual monitoring of subjects is necessary. PMID:26408646

    An electrode device for high pressure applications. These electrodes, designed to withstand pressure of greater than 10,000 psi, are adapted for use in microfluidic devices that employ electrokinetic or electrophoretic flow. The electrode is composed, generally, of an outer electrically insulating tubular body having a porous ceramic frit material disposed in one end of the outer body. The pores of the porous ceramic material are filled with an ion conductive polymer resin. A conductive material situated on the upper surface of the porous ceramic frit material and, thus isolated from direct contact with the electrolyte, forms a gas diffusion electrode. A metal current collector, in contact with the gas diffusion electrode, provides connection to a voltage source.

    2010-12-01

    The role of secondary refrigerants is expected to grow as the focus on the reduction of greenhouse gas emissions increases. The effectiveness of secondary refrigerants can be improved when phase changing media are introduced in place of single phase media. Operating at temperatures below the freezing point of water, ice slurry facilitates several efficiency improvements such as reductions in pumping energy consumption as well as lowering the required temperature difference in heat exchangers due to the beneficial thermo-physical properties of ice slurry. Research has shown that ice slurry can be engineered to have ideal ice particle characteristics so that it can be easily stored in tanks without agglomeration and then be extractable for pumping at very high ice fraction without plugging. In addition ice slurry can be used in many direct contact food and medical protective cooling applications. This paper provides an overview of the latest developments in ice slurry technology.

    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

  7. 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.

  8. Laser applications in neurosurgery

    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

  14. Applications of ion beams

    International Nuclear Information System (INIS)

    Charged particle accelerator was invented almost seven decades ago with the primary purpose to break the atomic nucleus. The broader inspiration, however, was to understand the structure of matter and the nature around us. Since then the accelerators have evolved enormously in terms of types, intricacies and sizes. They continue to play, primarily, the same role now also but have necessitated, over the years, invention and development of a large number of technologies that are being driven to cutting edge to meet the demands of scientists to carry their researches to unprecedented frontiers in various branches of science. While the first ever accelerator was built to break a 'simple' nucleus of lithium atom, the accelerators of today are trying to recreate the 'big bang' in the laboratory. They have been serving the scientists over the decades to discover new particles and fields. Charged particle accelerators are very commonly used to generate secondary beams for basic research and applications. The secondary beams include neutrons, antiprotons, mesons, neutrinos etc. In view of the experimentalists needs, accelerators have been developed both for electrons as well as ions. While the basic technologies do not differ much, the two varieties offer their own challenges. For each variety, the accelerator can be of linear type or circular type. Generally, a given accelerator accelerates either electrons or ions. In this report we shall be concerned only with the ion accelerators - more specifically about their applications. The accelerators most commonly used to accelerate ions are Cockroft Walton accelerator, Radio Frequency Quadrupole (RFQ) accelerator, Van-de- Graaff accelerator, linear accelerator (linac), cyclotron and synchrotron. In many situations they may operate in combination and, rarely, there exists hybrid variety also. (author)

  15. 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

  16. 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.

  17. Hydrogen energy applications

    International Nuclear Information System (INIS)

    For the Energy and Material consumption Scenarios (EMS), by which emission reduction of CO2 and other greenhouse gases can be calculated, calculations are executed by means of the MARKAL model (MARket ALlocation, a process-oriented dynamic linear programming model to minimize the costs of the energy system) for the Netherlands energy economy in the period 2000-2040, using a variable CO2 emission limit. The results of these calculations are published in a separate report (ECN-C--92-066). The use of hydrogen can play an important part in the above-mentioned period. An overview of several options to produce or use hydrogen is given and added to the MARKAL model. In this report techno-economical data and estimates were compiled for several H2-application options, which subsequently also are added to the MARKAL model. After a brief chapter on hydrogen and the impact on the reduction of CO2 emission attention is paid to stationary and mobile applications. The stationary options concern the mixing of natural gas with 10% hydrogen, a 100% substitution of natural gas by hydrogen, the use of a direct steam generator (combustion of hydrogen by means of pure oxygen, followed by steam injection to produce steam), and the use of fuel cells. The mobile options concern the use of hydrogen in the transportation sector. In brief, attention is paid to a hydrogen passenger car with an Otto engine, and a hydrogen passenger car with a fuel cell, a hybrid (metal)-hydride car, a hydrogen truck, a truck with a methanol fuel cell, a hydrogen bus, an inland canal boat with a hydrogen fuel cell, and finally a hydrogen airplane. 2 figs., 15 tabs., 1 app., 26 refs

    2001-04-01

    Four different composition of waterborne coating (WBC) were prepared by compounding of bentonite and synthetic hectorite (SHEC), a water swellable clay, with acrylic latex and coating additives. The rheological properties of WBC and the properties of the films casted by WBC were measured. The physical properties of the film surface of WBC on a printed paper were also investigated. WBC-3 and WBC-4 containing SHEC showed the phase transition of sol and gel with the shear rate, the thixotropic property, and accordingly, the dispersion and storage stability increased. The initial decomposition temperature and the transmittance of WBC films, which contained the water swellable clay, increased in range of 32.2 {approx} 54.7 degree C, and this was 5.9 {approx} 7.4% more than the commercial MC-21W. The domain size of water swellable clay in the WBC films decreased in the order of WBC-4 > WBC-3 > WBC-2. The water-resistance and the adhesion force of the film on the coated paper increased in the following order: MC-21W < WBC-4 < WBC-3 < WBC-2 < WBC-1, and MC-21W < WBC-2 {<=} WBC-4 = WBC-3 {<=} WBC-1, respectively. From these results, WBC-4, a WBC on the printed paper, containing 8 phr SHEC showed the maximum physical property excluding the water-resistance characteristics. 14 refs., 4 figs., 6 tabs.

    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.

    2016-08-01

    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. Microcomputer applications, (4)

    International Nuclear Information System (INIS)

    The high performance video image processing system with a microcomputer has been applied to various fields during recent years. In this paper, a video image processing system with a Z-80 (4MHz clock, 48KB DRAM) microcomputer and its application to neutron radiography are presented. The system has the following peripheral I/O devices; a TTY to control the system, a digital cassette tape recorder and two floppy disk drives to store the programs and the image data, a dot image printer to make a copy of an image on a CRT and a RS-232C interface to communicate with a host computer. The monitor and preliminary image processing softwares were developed with the machine language and stored in EPROMs (2708). The video image signals from the TV camera are digitized with about 33msec conversion-time/frame through a video A/D converter (ADC). The digitized image data can be stored in the image buffer (32KB DRAM) linked through the window address of the microcomputer system. The digitized pictures are taken with 16 levels of gray scale and resolved to 240 x 256 picture elements (pixels) on a monochrome CRT and displayed with 16 distinct colors on a RGB video display. The neutron radiography system installed at the E-2 experimental hole of the KUR(Kyoto University Reactor) has been available for some applications in non-destructive testing. To obtain real time radiographic images a video image processing system has been introduced in this facility. The resolution of image was obtained as about 0.5mm by a super highquality X-ray camera using a NE-426 neutron scintillator. The images of a NE-426 on CRT monitors can be observed directly and visually, and so many test samples can be continuously checked for industrial purpose. The direct image of this system could be satisfactory for penetrating the side plates to test MTR type reactor fuels and for the investigation of moving objects. (J.P.N.)

  12. Radiopharmaceuticals: therapeutic applications

    International Nuclear Information System (INIS)

    Radiopharmaceuticals are chemical compounds incorporating appropriate radionuclides, which are rendered suitable for human administration. It is the artificial production of radionuclide that laid the foundation of nuclear medicine. The basic principle in designing radiolabeled compounds for therapy is to achieve a high concentration of radioactivity in the target tissue which would be capable of delivering a desirable radiation dose with minimal exposure to the critical organ (usually bone marrow). With the availability of artificially produced radionuclides, therapeutic applications were initiated. Iodine-131 for the treatment of thyroid disorders has remained the most important one. Recent advances over the past 10 years are quite dramatic. There are three important areas where considerable research work is in progress. Intraarticular administration radiocolloids appear to be valuable for the management of synovitis in patients with rheumatoid arthritis. Palliative treatment of bone metastases and total-body bone marrow irradiation seem to be feasible with bone-seeking radiopharmaceuticals. Design and development of radiolabeled compounds for targeted delivery is important, such as (a) monoclonal antibodies for specific antigens, (b) peptides for specific receptors and (c) conjugated drugs for specific tumours. Radionuclide therapy is still in its infancy and present research activities reflect future potentials. (author). 76 refs., 4 figs., 2 tabs

  13. 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

  16. 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)

  17. Applications of chiral symmetry

    International Nuclear Information System (INIS)

    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 Tχ implies that the ρ and a1 vector mesons are degenerate in mass. In a gauged linear sigma model the ρ mass increases with temperature, mρ(Tχ) > mρ(0). The author conjectures that at Tχ the thermal ρ - a1, peak is relatively high, at about ∼1 GeV, with a width approximately that at zero temperature (up to standard kinematic factors). The ω meson also increases in mass, nearly degenerate with the ρ, but its width grows dramatically with temperature, increasing to at least ∼100 MeV by Tχ. 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 quenchedclose 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

  18. Energy applications of superconductivity

    International Nuclear Information System (INIS)

    The excitement over the new superconductors repeats the enthusiasm following the initial discovery in 1911 as well as that following the discovery of more practical metallic materials in the early 1960s. Higher temperature and the rapid progression from 35 K to 95 K and then to 125 K in a period of less than two years increased the normal enthusiasm to what could be described whimsically as hyperbole. Such excessive optimism led to some backlash and various expressions of pessimism in the media as the difficulty of the technical challenge of development was recognized. Now nearly five years after the initial discoveries and with fairly steady progress in both the science and the technology, the hype has been reduced and a more rational atmosphere prevails. This paper reports that high-temperature superconductivity generally promises an evolutionary rather than a revolutionary impact on energy applications. In other words, it could improve efficiency and reliability, but not make large power plants or petroleum obsolete

In Korea Cancer Center Hospital, PET is installed as a research tool of long-mid-term atomic research project. For the efficient use of PET for clinical and research projects, income from the patients should be managed to get the raw material, equipment, manpower, and also for the clinical PET research. 1. Support the clinical application of PET in oncology. 2. Budgetary management of income, costs for raw material, equipment, manpower, and the clinical PET research project. In this year, 250 cases of PET images were obtained, which resulted total income of 180,000,000 won. 50,000,000 won was deposited for the 1998 PET clinical research. Second year PET clinical research should be managed under unified project. Increased demand for {sup 18}FDG in and outside KCCH need more than 2 times production of {sup 18}FDG in a day purchase of HPLC pump and {sup 68}Ga pin source which was delayed due to economic crisis, should be done early in 1998.

  20. High energy applications

    International Nuclear Information System (INIS)

    Full text: From the point of view of high energy applications I would like to make the following recommendations: Neutron cross sections from the keV range up to 50 MeV are measured by dedicated mono- energetic fast neutron sources. For the design optimization of fast neutron sources, data files and models of proton and deuteron cross sections and their DDXs on Li and Be isotopes need to be improved utilizing recent experiments and new physics models for Ep dn,p < 2 GeV based on up-to-date physics models and available evaluated files, - identify target accuracies through sensitivity and uncertainty analyses using the recommended library; Inaccurate nuclear data can give rise to engineering margins of a factor 2 to 3 in high energy accelerator shielding design. Improving nuclear data of neutron inelastic scattering as well as activation cross sections for component, structural and shielding materials, such as Na, Al, Mn, Fe, Co, Ni, Cu, Zn for energies up to a few hundreds of MeV, is essential for the reduction of too conservative design margins, which in return would give a huge cost benefit; Radiation effects on micro-electronics (soft errors, damage) by cosmic-ray neutrons need to be predicted in a reliable way. Therefore, more reliable nuclear reaction models which can predict neutron-induced light-ion production from silicon in the incident energy range from MeV to GeV are strongly required. (author)

    In this invited lecture we give an overview of our 15 years of experience on streamer plasma research. Efforts are directed to integrating the competence areas of plasma physics, pulsed power technology and chemical processing. The current status is the development of a large scale pulsed corona system for gas treatment. Applications on biogas conditioning, VOC removal, odor abatement and control of traffic emissions have been demonstrated. Detailed research on electrical and chemical processes resulted in a boost of efficiencies. Energy transfer efficiency to the plasma was raised to above 90%. Simultaneous improvement of the plasma chemistry resulted in a highly efficient radical generation: O-radical production up to 50% of the theoretical maximum has been achieved. A major challenge in pulsed power driven streamers is to unravel, understand and ultimately control the complex interactions between the transient plasma, electrical circuits, and process. Even more a challenge is to yield electron energies that fit activation energies of the process. We will discuss our ideas on adjusting pulsed power waveforms and plasma reactor settings to obtain more controlled catalytic processing: the ``Chemical Transistor'' concept.

  3. Microcomputer applications, (3)

    International Nuclear Information System (INIS)

    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)

  4. 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

    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.

    Full Text Available Microcapsule is a tiny sphere including core material/internal phase or fill, coated with/surrounded by wall know as shell, coating or membrane. The usual size range of the microcapsule lies between 1 to 1000 μm. The technique is usually applied for targeted drug delivery, protection of the molecule and stability if the core material. Microencapsulation system offers potential advantages over conventional drug delivery systems and also established as unique carrier systems for many pharmaceuticals. This article contains the traditional and the recent pharmaceutical applications of microecapsules. The microcapsules are widely applied in pharmaceutical for Novel drug Delivery System (NDDS, latest formulations, Delivery of DNA Vaccines, Pro Drug Approach, Biodegradable and biocompatible material. Other then pharmaceutical microcapsules are widely used in delivery of probiotic, pesticide industry, food technology, beverages and cell immobilization etc. Although significant advances have been made in the field of microencapsulation, still many challenges need to be rectified during the appropriate selection of core materials, coating materials and process techniques.

  9. Clinical applications of radioimmunolocalisation

    International Nuclear Information System (INIS)

    Localization of tumours by external scintigraphy after intravenous administration of radiolabeled antibody directed against a tumour-associated antigen [radioimmunolocalisation (RIL)] might be expected to solve many of the problems of conventional tumour imaging. Although no truly specific tumour antigen is known, there are many tumour-associated antigens which are present in much higher concentrations in certain tumours than in tissues which are normal or affected by other diseases. This feature has the potential to endow RIL with a degree of specificity not exhibited by imaging methods such as computerised tomography (CT), ultrasound (US) or nuclear magnetic resonance (NMR) which reflect the physical characteristics of tissues. The clinical application of new imaging methods depends partly on their comparative performance in terms of sensitivity and specificity and also on ways in which the unique features of each can be exploited to optimize the management of individual patients. There are significant deficiencies with all the existing imaging methods; this chapter discusses the extent to which RIL may fill some of the gaps. Particular attention will be paid to situations where the result has consequences for patient management. Much of the work cited was carried out in experimental systems and on more than 300 patients at Charing Cross Hospital between 1979 and 1984

    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.
