    Automation systems are well established in industries and life science laboratories, especially in bioscreening and high-throughput applications. An increasing demand of automation solutions can be seen in the field of analytical measurement in chemical synthesis, quality control, and medical and pharmaceutical fields, as well as research and development. In this study, an automation solution was developed and optimized for the investigation of new biliary endoprostheses (stents), which should reduce clogging after implantation in the human body. The material inside the stents (incrustations) has to be controlled regularly and under identical conditions. The elemental composition is one criterion to be monitored in stent development. The manual procedure was transferred to an automated process including sample preparation, elemental analysis using inductively coupled plasma mass spectrometry (ICP-MS), and data evaluation. Due to safety issues, microwave-assisted acid digestion was executed outside of the automation system. The performance of the automated process was determined and validated. The measurement results and the processing times were compared for both the manual and the automated procedure. Finally, real samples of stent incrustations and pig bile were analyzed using the automation system.

    At the current level of stent application in urology each irreversible urostasis contraindicated for surgical therapy implies consideration of indications for metal stent insertion. Stent incrustation which leads directly into a new uroobstruction is a characteristic complication of this method. Available experience in different uroobstructive conditions has shown that very different clinical aspects of stent usage may directly determine the possibility of their incrustation. Stent incrustation may occur in the early postprocedural course or several months later. After that, prevention of stent incrustation starts with postprocedural evaluation, selection of the stent type, and it is subsequently continued by insertion technique and lasts practically permanently after the insertion (infection control, promotion of diuresis and maintenance of normal urodynamics). Authors present own experianse in clinical aplication of metal stents in uroradiology strictures for period of last 15 years.

    The results of an investigation indicate the following: (1) The deposition of incrustations on the heating surfaces of steam boilers can be prevented by inserting between heating surface and water an insulating layer on which the boiler incrustation will be deposited. (2) The insulating layer reduces the coefficient of heat transmission by 2%. (3) The insulating layer can be removed by macrosounds with a frequency of about 20 kHz, after any interval of boiler operation.

    Scientific research at universities has a crucial role in leveraging a country's innovative potential. Sectors that require greater investments in technology for the development of their research, such as biotechnology, need to be aware of the frontier state-of-the-art technology and the knowledge incrusted within it. Although the information available in scientific articles is well explored in academic environment, the patent literature, where much of the technological information is present, is still poorly accessed. This chapter is intended to instruct students and researchers at universities to look at patent document analysis as a source of scientific and technological information and explore its applications. Within this chapter, we use the technological area regarding immunoglobulins inventions (monoclonal and polyclonal antibodies) as example to provide directions on how to develop a patent landscape to get an overview of the inventions in a certain field; how to map a collaborative network of inventors/assignees to help the pursuit and identification of future partnerships; and lastly we describe the steps of how to set up a network of patent citations with the aim of forecasting emerging technologies. We strongly believe that incorporate data from patents in planning phase of research projects at academia, as well as to establish partnerships and join R&D efforts to invest on promising technologies, is of great relevance to leverage the growth of the biotechnology sector.

    The clustering behavior and cluster composition of hermit crabs as well as the patterns of shell utilization of clustered and scattered individuals were studied. This study was conducted in the intertidal region of Grande Beach, São Sebastião, southeastern Brazil. Samples were taken both in randomized transects and 1 m2 quadrats during low tide periods. Crabs were counted, measured (shield length), and sexed. Shells were identified and had their adequacy and condition (physical damage and incrustation) recorded. Clusters occurred mainly in air exposed areas and were dominated or composed only by Clibanarius antillensis. Other species like Paguristes tortugae, Pagurus criniticornis, and Calcinus tibicen were also present in these clusters, but in small numbers. Only one monospecific aggregation composed by individuals of P. criniticornis was recorded in tide pools. Almost all crabs were inactive, despite some that were submerged in tide pools. Most of the individuals of C. antillensis were clustered (70.88%). Scattered individuals were larger than clustered ones and occupied mainly shells of Tegula viridula, which seemed to be the most adequate shell to the crabs. Clustered individuals used less incrusted shells than isolated ones. In general, clustering in Grande Beach presented the same patterns of size and sex distribution, and shell utilization than others already studied, with the exception of the smaller cluster size registered in this area.

    In order to avoid incrustation and an excessively strong thermal attack on the afterburning chamber, the exhaust gases which contain gaseous and solid constituents which are combustible are afterburned in a plurality of stages, which are connected in series. The rate at which oxygen is supplied to each stage is so controlled that part of the combustible constituents is afterburned in each stage. The gas which is about to enter each succeeding stage is cooled by injected water.

    Four sections were measured along a 1/4 mi length of Little Walnut Creek. The first section was 165 ft north of the US. 290 bridge while the fourth was 1/4 mi upstream. Structurally, the stream follows the fault in this section. Small faults can be found perpendicular to the primary fault and apparently account not only for minor variation in local dip (8{degrees}SE, parallel to 5{degrees}NW) but also for the placement of at least one tributary. Megainvertebrate exoskeletons were found to have been inhabited by incrusting bryozoans, boring bryozoans, and sponges. These fossils were found on both interior and exteriormore » surfaces of Exogyra laeviuscula E tigrina, and interior surfaces of Inoceramus. A low-energy environment allowed exposure of megainvertebrate exoskeletons after death but also prevented fracturing. Low siltation rates also extended exoskeleton availability after organismic death. The nonboring bryozoans are cheilostomes and at least one species, Pyripora, has been described from the Kansas Cretaceous as well as European Cretaceous sites. The boring bryozoans are primarily represented by Terebripora sp. In conclusion, this section of Dessau Chalk Formation, Upper Austin Group, was mostly a low-energy environment, shallow, limy mud platform. This substrate was probably not stable enough for bryozoan colonization as unattached colonies have not been found in sediments. Therefore, bryozoan substrates were limited to living and dead Exogyra sp. and dead Inoceramus sp. exoskeletons.« less

  11. Barite aerosol particles from volcanic plumes and fumaroles - FESEM/EDS analysis

    Studies of aerosol particles (AP) contained in volcanic plumes has been enormously benefited by the use of field emission scanning electron microscope (FESEM/EDS; responsability by H. Schroettner) permitting morphological, mineralogical and chemical detailed observations and opening new scientific questions. This work shows the ubiquitous presence of Ba in volcanic emissions. We sampled e.g. a volcanic plume (Popocatepetl v.; 1997, 2002) revealing Ba-S-O particles, interpreteted as barite (BaSO4) and Sr-bearing barite with Fe-rich rim (w=1µm). The ca. 500 nm - 4 µm long crystals are +/- euhedral, anhedral and/or partially etched. The µm-sized crystals had been collected on a Teflon fiber filter (1997), the nm-sized on borosilicate fiber filter (BFF, 2002); one set of crystals (ca. l=500-800 nm) is scattered on Fe-hydr/oxide(?). APs collected from the degassing lava flow of Etna (2001) revealed barite (l= ca. 100 nm) on a rounded NaCl (d= 500 nm) and on Fe-hydr/oxides (?). BFF exposed to the F0 fumarole at Vulcano (2001) showed incrustations of barite (l=ca.200 nm) on fibers indicating barite formation during 5 min sampling. At Solfatra we observed almost euhedral barite particles (l=ca.300 nm) of unusual pseudo-trigonal shape. APs from Alpine air masses (A) did not reveal barite. Sources for barite could be vesicle fillings of lavas (known from continental-crust settings), vapor-phase crystallization of ignimbrites (Bandelier Tuff, USA), Ba-rich fumarolic incrustations, rock coatings in the vicinity of fumaroles (Vulcano, I.), sinter of hot springs (Akita-Yaka-Yama v., J.), barite veins (Milos, Gr.), contact-metamorphosed sedimentary xenoliths (Kloech, A.) or lithics associated with hydrovolcanic eruptions (Alban Hills v., I.). Barite has been observed in many Si-tube experiments. Stratospheric APs (1985) of the El Chichon eruption (1982) revealed barite. Ba is known as a trace element in fumarole gases of Vulcano (F11) and TOF mass spectrometry studies detected 138Ba++ in the upper troposphere over Mexico (1998). Barite APs being the product of fragmented rocks would be very rare. The incrustations on fibrous filters at Vulcano indicate that Ba species exist in fumarolic gases. Can barite be used as a proxy for volcanic signals in ice cores or other environments? Do Ba species exist in all volcanic gases or are there speciations according to plate tectonic settings? What the effects might be of Ba in fumaroles, plumes interacting with the atmosphere? Ba-rich particles are known as natural ice-forming nuclei.

    Airborne Visible/Near-Infrared Imaging Spectrometer (AVIRIS) data acquired over the Ka u Desert are atmospherically corrected to ground reflectance and used to identify the mineralogic components of relatively young basaltic materials, including 250-700 and 200-400 year old lava flows, 1971 and 1974 flows, ash deposits, and solfatara incrustations. To provide context, a geologic surface units map is constructed, verified with field observations, and supported by laboratory analyses. AVIRIS spectral endmembers are identified in the visible (0.4 to 1.2 ??m) and short wave infrared (2.0 to 2.5 ??m) wavelength ranges. Nearly all the spectral variability is controlled by the presence of ferrous and ferric iron in such minerals as pyroxene, olivine, hematite, goethite, and poorly crystalline iron oxides or glass. A broad, nearly ubiquitous absorption feature centered at 2.25 ??m is attributed to opaline (amorphous, hydrated) silica and is found to correlate spatially with mapped geologic surface units. Laboratory analyses show the silica to be consistently present as a deposited phase, including incrustations downwind from solfatara vents, cementing agent for ash duricrusts, and thin coatings on the youngest lava flow surfaces. A second, Ti-rich upper coating on young flows also influences spectral behavior. This study demonstrates that secondary silica is mobile in the Ka u Desert on a variety of time scales and spatial domains. The investigation from remote, field, and laboratory perspectives also mimics exploration of Mars using orbital and landed missions, with important implications for spectral characterization of coated basalts and formation of opaline silica in arid, acidic alteration environments.

  13. Kaolinite, illite and quartz dissolution in the karstification of Paleozoic sandstones of the Furnas Formation, Paraná Basin, Southern Brazil

    Karstification processes in sandstones of the Furnas Formation, Silurian to Devonian of the Paraná Basin, have been described since the mid-twentieth century. However, some geologists still doubt the idea of true karst in sandstones. Studies carried out in the Campos Gerais region, Paraná State, Southern Brazil, aimed at investigating the nature of erosion processes in Furnas Formation and the role of the dissolution in the development of their notorious erosive features and underground cavities. These studies have led to the recognition of dissolution macro to micro features ('furnas', caves, ponds, sinks, ruiniform relief on cliffs and rocky surfaces, grain corrosion, speleothems, mineral reprecipitation and incrustation). The analysis (scanning electron microscopy, energy dispersive spectrometry and x-ray diffractometry) of sandstones and their alterites has indicated significant dissolution of clay cement along with discrete quartz grain dissolution. This mesodiagenetic cement (kaolinite and illite) is dissolved and reprecipitated as clay minerals with poorly developed crystallinity along with other minerals, such as variscite and minerals of the alunite supergroup, suggesting organic participation in the processes of dissolution and incrustation. The mineral reprecipitation usually forms centimetric speleothems, found in cavities and sheltered rocky surfaces. The cement dissolution associated with other factors (fractures, wet weather, strong hydraulic gradient, antiquity of the landforms) leads to the rock arenisation, the underground erosion and the appearance of the karst features. Carbonate rocks in the basement may locally be increasing the karst forms in the overlying Furnas Formation. The recognition of the karst character of the Furnas Formation sandstones has important implications in the management of underground water resources (increasingly exploited in the region), in the use of the unique geological heritage and in the prevention of geo-environmental accidents resulting from underground erosion phenomena.

  14. Fossil and active fumaroles in the 1912 eruptive deposits, Valley of ten thousand smokes, Alaska

    Keith, T.E.C.

    1991-01-01

    Fumaroles in the ash-flow sheet emplaced during the 1912 eruption of Novarupta were intensely active throughout the Valley of Ten Thousand Smokes (VTTS) when first studied in 1917. Fumarole temperatures recorded in 1919 were as hot as 645??C. Influx of surface waters into the hot ash-flow sheet provided the fluid flow to sustain the fumaroles but also enhanced cooling so that by the mid-1930's vigorous activity survived only in the vent region. Configuration and distribution of high-temperature fissure fumaroles tens of meters long, that are prevalent in the middle and upper VTTS, were controlled largely by sintering and degree of welding, which in turn controlled fracturing and permeability of the ash-flow tuff. One fracture type developed parallel to the enclosing valley walls during compaction of the ash-flow sheet. Another type extends across the VTTS nearly perpendicular to the flow direction. A third type of randomly oriented fractures developed as cooling contraction cracks during vapor-phase devitrification. In distal parts of the ash-flow sheet where the tuff is nonwelded, prominent fumaroles have irregular funnel-shaped morphologies. Fumarole distribution in the nonwelded part of the ash-flow sheet is concentrated above pre-emplacement river channels. The hottest, longest-lived fumaroles occurred in the upper VTTS near the 1912 vent where the ash-flow sheet is thicker, more indurated, and on average more mafic (richer in dacite and andesite) in contrast to the thinner, nonwelded rhyolitic tuff in the distal part of the sheet. Fumarolic activity was less intense in the distal part of the tuff because of lower emplacement temperatures, more diffuse fumarole conduits in the nonwelded tuff, and the thinness of the ash-flow sheet. Chemical leaching of ash-flow tuff by hot rising fluids took place adjacent to fumarolic conduits in deep parts of the fumaroles. Deposition of incrustation minerals, the components of which were carried upward by fumarolic gases, took place in the upper part of the ejecta, mostly in the fallout layers. The permeability difference between the ash-flow tuff and the overlying coarse dacite fallout was a critical factor in promoting the abrupt gradients in temperature, pressure, and fO2 that resulted in deposition of minerals from the fumarolic gases. The permeability difference between nonwelded ash-flow tuff and overlying fine-grained fall layers in the lower VTTS is less pronounced. The total mass of fumarolically deposited minerals appears large at first glance owing to the conspicuous coloration by Fe minerals; the mass is appreciably less than is apparent, however, because most incrustations are composed largely of ejecta coated or cemented by fine-grained fumarolic minerals. A large mass of unstable incrustation minerals, mainly chlorides and sulfates, reported during the 1917-1919 studies have since been removed by dissolution and weathering. In the vent region, argillic alteration that followed high-temperature degassing is localized along arcuate subsidence fractures in fallback ejecta. At widely scattered residual orifices, fumarolic gases presently are near-neutral steam, and temperatures are as hot as 90??C. ?? 1991.

    Energy filtering TEM (EFTEM) with modern spectrometers and software offers new possibilities for element analysis and image generation in plant cells. In the present review, applications of EFTEM in plant physiology, such as identification of light elements and ion transport, analyses of natural cell incrustations, determination of element exchange between fungi and rootlets during mycorrhiza development, heavy metal storage and detoxification, and employment in plant physiological experiments are summarized. In addition, it is demonstrated that EFTEM can be successfully used in more practical approaches, for example, in phytoremediation, food and wood industry, and agriculture. Preparation methods for plant material as prerequisites for EFTEM analysis are compared with respect to their suitability and technical problems are discussed.

  16. PGE in fresh basalt, hydrothermal alteration products, and volcanic incrustations of Kilauea volcano, Hawaii

    Crocket, James H.

    2000-05-01

    The concentrations of Os, Ir, Pd, and Au in fresh unaltered Kilauean tholeiite were determined by radiochemical neutron activation analysis. For a suite of 18 samples, averages were: Os = 0.38 ± 0.23, Ir = 0.38 ± 0.14, Pd = 2.40 ± 1.04, and Au = 1.78 ± 0.57 (in ppb with a 1σ SD). Correlations of these metals with Co, Cr, Cu, Ni, and MgO in fresh basalts, and petrographic observations, indicate that Os and Ir are carried mainly in chromite, much of which occurs as inclusions in olivine phenocrysts. Palladium correlations suggest its occurrence partly in olivine and partly in the matrix whereas Au seems to be predominantly a matrix constituent. Altered basalts were analyzed for Ir, Pd, and Au in a suite of 19 samples from five different locations. Minor changes only in either concentrations or element ratios were found for Ir and Pd when fresh and altered rock data were compared. However, Au was consistently enriched in altered relative to fresh rocks. These results imply that Pd and Ir, in contrast to Au, will likely retain their eruptive signatures upon burial in a subaerial eruptive setting. High-temperature sulfate-dominated condensates generate incrustations enriched in Ir, Os, Au, and Pd by approximately 50, 20, 10, and 3×, respectively, relative to fresh rocks. In contrast, low-temperature native sulfur deposits are the most depleted material found in the study with Ir, Pd, and Au lower by factors of 10, 4, and 5 compared with fresh rock averages. The strong enrichments of Os and Ir in the high-temperature suite are attributed mainly to enhanced volatility in highly oxygenated magmatic hydrothermal fluids contaminated by meteoric water near the structural top of volcanic conduits. The relatively smaller Pd enrichment, which is dependent on the chloride content of fluids, implies that PGE partitioning into volcanic fume may fractionate these metals (e.g., Pd versus Ir) relative to host basalt in the eruptive process.

    Aim of study was to present costs of forgotten ureteral stents extraction so as to distract attentions of the urologists on this issue. Medical files of 27 accessible patients who referred to our clinics between 2001 and 2010 because of forgotten ureteral stent were retrospectively analyzed. The indwelling time of double-j stents (DJS) was calculated from the time of its insertion. Costs related to radiological investigations, all invasive, and noninvasive interventions, duration of hospital stay, and medical treatments used were calculated. These estimations were based on 2010 prices determined by Turkey Ministry of Health. Mean age of the patients was 31.2 (8-86 years) years. Mean indwelling time of ureteral DJSs was 36.7 months (14-84 months). Seventy-one [extracorporeal shock wave lithotripsy (ESWL), n = 26; invasive/noninvasive interventions, n = 32] procedures were applied for 27 patients. In six patients without incrustation, after a single session of ESWL DJSs could be removed cystoscopically. A various combination of a multimodal therapy was used for other 21 patients. Total financial burden of 27 patients was US $ 34,300. Cost of treatment was estimated to be 6.9-fold (1.8- to 21-fold) higher than an average timely stent extraction. Financial burden of the treatments increased in parallel with the duration of the stent retention (p = 0.001). Management of forgotten DJS is time consuming, difficult, complicated, risky, and costly. Therefore; financial burden, increased labour loss, and impaired quality of life brought by the application of these modalities must not be forgotten.

  18. Suitability of biogenic carbonate of Lithospermum fruits for 14C dating

    Pustovoytov, Konstantin; Riehl, Simone

    2006-05-01

    Lithospermum (Boraginaceae) belongs to a small group of plant taxa that accumulate biogenic carbonate in their fruits. In this genus, carbonate incrustations form in the cells of the epidermis and sclerenchyma of the pericarp. Fossil Lithospermum fruits (nutlets) with well-preserved calcified tissues commonly occur in Quaternary sediments and cultural layers. We tested the suitability of biogenic carbonate of Lithospermum fruits for radiocarbon dating using a total of 15 AMS measurement results from four modern and 11 fossil samples. The 14C data from modern samples suggest that Lithospermum utilises only atmospheric carbon to synthesise calcite in the nutlets. In general, the ages determined through 14C dating of fossil fruitscorresponded well with the absolute-age intervals for archaeological sites over the last 5000 yr. Biogenic carbonate of Lithospermum fruits, like that of Celtis, represents a new source of chronological information for late Quaternary studies.

    Although the use of polytetrafluoroethylene (PTFE)-covered biliary stents has proven to be feasible for the treatment of benign and malignant biliary disease, less is known regarding the outcomes of percutaneous placement of a covered stent in patients with malignant duodenobiliary obstruction. To investigate the technical and clinical efficacy of the percutaneous placement of a PTFE-covered biliary stent in patients with malignant duodenobiliary obstruction. From April 2007 to September 2012, the medical records of 45 consecutive patients with malignant duodenobiliary obstruction were retrospectively reviewed. All percutaneous biliary stent deployment was performed using PTFE-covered stents, whereas duodenal stent insertion was performed either fluoroscopically or endoscopically using covered or uncovered stents. Biliary stent deployment was technically successful in all patients. None of the stents migrated after deployment. Procedure-related minor complications, including self-limiting hemobilia, occurred in three (7%) patients. Successful internal drainage was achieved in 39 (87%) of the 45 patients. The median survival time after biliary stent placement was 62 days (95% confidence interval, 8-116 days), and the cumulative stent patency rates at 1, 3, 6, and 12 months were 96%, 92%, 75%, and 38%, respectively. The causes of biliary stent dysfunction included stent occlusion caused by a subsequently inserted duodenal stent (n = 7), food impaction (n = 3), and sludge incrustation (n = 1). One patient developed acute cholecystitis 131 days after biliary stent placement and underwent percutaneous transhepatic gallbladder drainage. Percutaneous insertion of a PTFE-covered stent is a safe and effective method for palliative treatment of patients with malignant duodenobiliary obstruction. If possible, subsequent biliary stent insertion is preferable in order to prevent possible biliary stent dysfunction caused by subsequent insertion of a duodenal stent. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    A double stent system (covered stent in uncovered stent) was designed to provide long-term patency without tumor ingrowth or stent-related complications, such as stent migration, cholecystitis, or pancreatitis. To investigate the safety and efficacy of double stents in patients with malignant extrahepatic biliary obstructions. This prospective, nonrandomized, multicenter study enrolled 160 consecutive patients (102 men; mean age, 64 years; range, 33-91 years) with malignant extrahepatic biliary obstructions treated with a double stent system from January 2010 to March 2012. The technical success rate of the double stent placement was 100%. No stent migration was observed. Procedure-related minor (self-limiting hemobilia [n = 6] and cholangitis [n = 2]) and major (pancreatitis [n = 16], cholecystitis [n = 3], and hepatic abscess [n = 2]) complications occurred in a total of 29 patients. The mean serum bilirubin level, which was 8.9 ± 5.6 mg/dL before drainage, decreased to 2.2 ± 4.6 mg/dL 1 month after stent placement (P < 0.001). Successful internal drainage was achieved in 148 patients (92.5%). During the mean follow-up period of 205 days, acute cholecystitis (n = 3) and hepatic abscess (n = 2) occurred in five patients. The median patient survival and stent patency time were 135 days (95% confidence interval [CI], 96-160 days) and 114 days (95% CI, 83-131 days), respectively.

    The morphology and the micro-structural changes of levonorgestrel-releasing intrauterine systems (IUSs) were studied in relation to the duration of their application. The morphology of the removed IUSs was examined without pre-treatment by scanning electron microscopy. The micro-structural changes of the different layers of IUSs were tracked by positron annihilation lifetime spectroscopy. Besides the previously found incrustation formation, the free volume of the hormone containing reservoir was remarkably increased after 3 years of application, thus increasing the real volume of the core of the systems. Although the free volume of the membrane encasing the core was not significantly changed in the course of the application, as a result of the core expansion, microcracks could be formed on the membrane surface. Along these cracks, deposits of different compositions can be formed, causing inflammatory complications and influencing the drug release of IUSs. Stability tests in combination with micro-structural screening of such IUSs could be required during their development phase to avoid the undesired side effects. Copyright (c) 2010 Elsevier B.V.

    The National Aeronautics and Space Administration (NASA) tasked The MITRE Corporation's Center for Advanced Aviation System Development (CAASD) to investigate potential air traffic control (ATC) procedures that could benefit from technology used or developed in NASA's Wake Vortex Advisory System (WakeVAS). The task also required developing an estimate of the potential benefits of the candidate procedures. The main thrust of the investigation was to evaluate opportunities for improved capacity and efficiency in airport arrival and departure operations. Other procedures that would provide safety enhancements were also considered. The purpose of this investigation was to provide input to the WakeVAS program office regarding the most promising areas of development for the program. A two-fold perspective was desired: First, identification of benefits from possible procedures enabled by both incremental components and the mature state of WakeVAS technology; second identification of procedures that could be expected to evolve from the current Federal Aviation Administration (FAA) procedures. The evolution of procedures should provide meaningful increments of benefit and a low risk implementation of the WakeVAS technologies.

  12. Recent sediment remolding on a deep shelf, Ross Sea: implications for radiocarbon dating of Antarctic marine sediments

    NASA Astrophysics Data System (ADS)

    Domack, Eugene W.; Taviani, Marco; Rodriguez, Anthonio

    1999-11-01

    Coarse, bioclastic rich sands have been widely reported from the banks of the Antarctic continental shelf but their origin is still poorly known. We report on a suite of coarse sediments recovered from the top of the Mawson Bank in the northwestern Ross Sea. Radiocarbon ages of biogenic calcite, for modern and apparently late Pleistocene deposits, range from 1085±45 to 20,895±250 yr B.P.. Discovery of soft tissue (Ascidian) preserved as an incrustation on a pebble at 2 m depth indicates aggregation of the sediment within several months or a year of core recovery. Radiocarbon ages of acid insoluble organic matter (aiom) are less than those of the foraminifera calcite. The aiom ages are also reversed in sequence, indicating reworking of the sediment during deposition. These observations and a review of recently published literature suggest that much of the bank top sediment in Antarctica is presently undergoing remobilization, under the influence of strong currents and/or icebergs even under interglacical (high-stand) sea levels. These observations point out the need for careful, integrated studies on high latitude marine sediment cores before resultant "ages" alone are used as the foundation for paleoglacial reconstructions.

  13. Detection of iron-depositing Pedomicrobium species in native biofilms from the Odertal National Park by a new, specific FISH probe.

    Braun, Burga; Richert, Inga; Szewzyk, Ulrich

    2009-10-01

    Iron-depositing bacteria play an important role in technical water systems (water wells, distribution systems) due to their intense deposition of iron oxides and resulting clogging effects. Pedomicrobium is known as iron- and manganese-oxidizing and accumulating bacterium. The ability to detect and quantify members of this species in biofilm communities is therefore desirable. In this study the fluorescence in situ hybridization (FISH) method was used to detect Pedomicrobium in iron and manganese incrusted biofilms. Based on comparative sequence analysis, we designed and evaluated a specific oligonucleotide probe (Pedo 1250) complementary to the hypervariable region 8 of the 16S rRNA gene for Pedomicrobium. Probe specificities were tested against 3 different strains of Pedomicrobium and Sphingobium yanoikuyae as non-target organism. Using optimized conditions the probe hybridized with all tested strains of Pedomicrobium with an efficiency of 80%. The non-target organism showed no hybridization signals. The new FISH probe was applied successfully for the in situ detection of Pedomicrobium in different native, iron-depositing biofilms. The hybridization results of native bioflims using probe Pedo_1250 agreed with the results of the morphological structure of Pedomicrobium bioflims based on scanning electron microscopy.

    The low-temperature low-pressure hydrogen based plasmas were used to study the influence of processes and discharge conditions on corrosion removal. The capacitive coupled RF discharge in the continuous or pulsed regime was used at operating pressure of 100-200 Pa. Plasma treatment was monitored by optical emission spectroscopy. To be able to study influence of various process parameters, the model corroded samples with and without sandy incrustation were prepared. The SEM-EDX analyzes were carried out to verify corrosion removal efficiency. Experimental conditions were optimized for the selected most frequent materials of original metallic archaeological objects (iron, bronze, copper, and brass). Chlorides removal is based on hydrogen ion reactions while oxides are removed mainly by neutral species interactions. A special focus was kept for the samples temperature because it was necessary to avoid any metallographic changes in the material structure. The application of higher power pulsed regime with low duty cycle seems be the best treatment regime. The low pressure hydrogen plasma is not applicable for objects with a very broken structure or for nonmetallic objects due to the non-uniform heat stress. Due to this fact, the new developed plasmas generated in liquids were applied on selected original archaeological glass materials.

  15. Composition of weathering crusts on sandstones from natural outcrops and architectonic elements in an urban environment.

    2014-12-01

    This work presents mineralogical and chemical characteristics of weathering crusts developed on sandstones exposed to various air pollution conditions. The samples have been collected from sandstone tors in the Carpathian Foothill and from buildings in Kraków. It has been stated that these crusts differ in both fabric and composition. The sandstone black crust from tors is rich in organic matter and composed of amorphous silica. Sulphate incrustations accompanied by dust particles have been only sometimes observed. Beneath the black crust, a zone coloured by iron (oxyhydr)oxides occurs. The enrichment of the surface crust in silica and iron compounds protects the rock interior from atmospheric impact. The sandstones from architectonic details are also covered by a thin carbon-rich black crust, but they are visibly loosened. Numerous salts, mainly gypsum and halite, crystallise here, thus enhancing deterioration of the rock. Moreover, spherical particles originated from industrial emissions are much more common. Gypsum in natural outcrops, forms isolated and well-developed crystals, whilst these found on the architectonic details are finer and densely cover the surface. Such diversity reflects various concentrations of acid air pollutants in solutions.

    2013-09-01

    Pipeline scales from the Campos Bay Petroleum Field near Rio de Janeiro, Brazil have been analyzed by both Raman spectroscopy and by laser-induced breakdown spectroscopy (LIBS) using a double-pulse, calibration-free approach. Elements that are characteristic of petroleum (e.g. C, H, N, O, Mg, Na, Fe and V) were detected, in addition to the Ca, Al, and Si which form the matrix of the scale. The LIBS results were compared with the results of micro-Raman spectroscopy, which confirmed the nature of the incrustations inferred by the LIBS analysis. Results of this preliminary study suggest that diffusion of pipe material into the pipeline intake column plays an important role in the growth of scale. Thanks to the simplicity and relative low cost of equipment and to the fact that no special chemical pre-treatment of the samples is needed, LIBS can offer very fast acquisition of data and the possibility of in situ measurements. LIBS could thus represent an alternative or complementary method for the chemical characterization of the scales by comparison to conventional analytical techniques, such as X-ray diffraction or X-ray fluorescence.

    The development of navigation technology facilitating MRI-guided stereotactic neurosurgery has enabled neurosurgeons to perform a variety of procedures ranging from deep brain stimulation to laser ablation entirely within an intraoperative or diagnostic MRI suite while having real-time visualization of brain anatomy. Prior to this technology, some of these procedures required multisite workflow patterns that presented significant risk to the patient during transport. For those facilities with access to this technology, safe practice guidelines exist only for procedures performed within an intraoperative MRI. There are currently no safe practice guidelines or parameters available for facilities looking to integrate this technology into practice in conventional MRI suites. Performing neurosurgical procedures in a diagnostic MRI suite does require precautionary measures. The relative novelty of technology and workflows for direct MRI-guided procedures requires consideration of safe practice recommendations, including those pertaining to infection control and magnet safety issues. This article proposes a framework of safe practice recommendations designed for assessing readiness and optimization of MRI-guided neurosurgical interventions in the diagnostic MRI suite in an effort to mitigate patient risk. The framework is based on existing clinical evidence, recommendations, and guidelines related to infection control and prevention, health care-associated infections, and magnet safety, as well as the clinical and practical experience of neurosurgeons utilizing this technology. © 2017 American Society for Healthcare Risk Management of the American Hospital Association.

  19. Beyond Volume: Hospital-Based Healthcare Technology for Better Outcomes in Cerebrovascular Surgical Patients Diagnosed With Ischemic Stroke: A Population-Based Nationwide Cohort Study From 2002 to 2013.

    We examined whether the level of hospital-based healthcare technology was related to the 30-day postoperative mortality rates, after adjusting for hospital volume, of ischemic stroke patients who underwent a cerebrovascular surgical procedure. Using the National Health Insurance Service-Cohort Sample Database, we reviewed records from 2002 to 2013 for data on patients with ischemic stroke who underwent cerebrovascular surgical procedures. Statistical analysis was performed using Cox proportional hazard models to test our hypothesis. A total of 798 subjects were included in our study. After adjusting for hospital volume of cerebrovascular surgical procedures as well as all for other potential confounders, the hazard ratio (HR) of 30-day mortality in low healthcare technology hospitals as compared to high healthcare technology hospitals was 2.583 (P < 0.001). We also found that, although the HR of 30-day mortality in low healthcare technology hospitals with high volume as compared to high healthcare technology hospitals with high volume was the highest (10.014, P < 0.0001), cerebrovascular surgical procedure patients treated in low healthcare technology hospitals had the highest 30-day mortality rate, irrespective of hospital volume. Although results of our study provide scientific evidence for a hospital volume/30-day mortality rate relationship in ischemic stroke patients who underwent cerebrovascular surgical procedures, our results also suggest that the level of hospital-based healthcare technology is associated with mortality rates independent of hospital volume. Given these results, further research into what components of hospital-based healthcare technology significantly impact mortality is warranted.

  20. Volatilization, transport and sublimation of metallic and non-metallic elements in high temperature gases at Merapi Volcano, Indonesia

    Condensates, silica tube sublimates and incrustations were sampled from 500-800??C fumaroles and lava samples were collected at Merapi Volcano, Indonesia in Jan.-Feb., 1984. With respect to the magma, Merapi gases are enriched by factors greater than 105 in Se, Re, Bi and Cd; 104-105 in Au, Br, In, Pb and W; 103-104 in Mo, Cl, Cs, S, Sn and Ag; 102-103 in As, Zn, F and Rb; and 1-102 in Cu, K, Na, Sb, Ni, Ga, V, Fe, Mn and Li. The fumaroles are transporting more than 106 grams/day ( g d) of S, Cl and F; 104-106 g/d of Al, Br, Zn, Fe, K and Mg; 103-104 g d of Pb, As, Mo, Mn, V, W and Sr; and less than 103 g d of Ni, Cu, Cr, Ga, Sb, Bi, Cd, Li, Co and U. With decreasing temperature (800-500??C) there were five sublimate zones found in silica tubes: 1) cristobalite and magnetite (first deposition of Si, Fe and Al); 2) K-Ca sulfate, acmite, halite, sylvite and pyrite (maximum deposition of Cl, Na, K, Si, S, Fe, Mo, Br, Al, Rb, Cs, Mn, W, P, Ca, Re, Ag, Au and Co); 3) aphthitalite (K-Na sulfate), sphalerite, galena and Cs-K. sulfate (maximum deposition of Zn, Bi, Cd, Se and In; higher deposition of Pb and Sn); 4) Pb-K chloride and Na-K-Fe sulfate (maximum deposition of Pb, Sn and Cu); and 5) Zn, Cu and K-Pb sulfates (maximum deposition of Pb, Sn, Ti, As and Sb). The incrustations surrounding the fumaroles are also chemically zoned. Bi, Cd, Pb, W, Mo, Zn, Cu, K, Na, V, Fe and Mn are concentrated most in or very close to the vent as expected with cooling, atmospheric contamination and dispersion. The highly volatile elements Br, Cl, As and Sb are transported primarily away from high temperature vents. Ba, Si, P, Al, Ca and Cr are derived from wall rock reactions. Incomplete degassing of shallow magma at 915??C is the origin of most of the elements in the Merapi volcanic gas, although it is partly contaminated by particles or wall rock reactions. The metals are transported predominantly as chloride species. As the gas cools in the fumarolic environment, it becomes saturated with sublimate phases that fractionate from the gas in the order of their equilibrium saturation temperatures. Devolatilization of a cooling batholith could transport enough acids and metals to a hydrothermal system to play a significant role in forming an ore deposit. However, sublimation from a high temperature, high velocity carrier gas is not efficient enough to form a large ore deposit. Re, Se, Cd and Bi could be used as supporting evidence for magmatic fluid transport in an ore deposit. ?? 1987.

  1. Fumaroles in ice caves on the summit of Mount Rainier: preliminary stable isotope, gas, and geochemical studies

    The edifice of Mount Rainier, an active stratovolcano, has episodically collapsed leading to major debris flows. The largest debris flows are related to argillically altered rock which leave areas of the edifice prone to failure. The argillic alteration results from the neutralization of acidic magmatic gases that condense in a meteoric water hydrothermal system fed by the melting of a thick mantle of glacial ice. Two craters atop a 2000-year-old cone on the summit of the volcano contain the world's largest volcanic ice-cave system. In the spring of 1997 two active fumaroles (T=62°C) in the caves were sampled for stable isotopic, gas, and geochemical studies. Stable isotope data on fumarole condensates show significant excess deuterium with calculated δD and δ18O values (−234 and −33.2‰, respectively) for the vapor that are consistent with an origin as secondary steam from a shallow water table which has been heated by underlying magmatic–hydrothermal steam. Between 1982 and 1997, δD of the fumarole vapor may have decreased by 30‰. The compositions of fumarole gases vary in time and space but typically consist of air components slightly modified by their solubilities in water and additions of CO2 and CH4. The elevated CO2 contents δ13CCO2 = -11.8±0.7‰, with spikes of over 10,000 ppm, require the episodic addition of magmatic components into the underlying hydrothermal system. Although only traces of H2S were detected in the fumaroles, most notably in a sample which had an air δ13CCO2 signature (−8.8‰), incrustations around a dormant vent containing small amounts of acid sulfate minerals (natroalunite, minamiite, and woodhouseite) indicate higher H2S (or possibly SO2) concentrations in past fumarolic gases. Condensate samples from fumaroles are very dilute, slightly acidic, and enriched in elements observed in the much higher temperature fumaroles at Mount St. Helens (K and Na up to the ppm level; metals such as Al, Pb, Zn Fe and Mn up to the ppb level and volatiles such as Cl, S, and F up to the ppb level). The data indicate that the hydrothermal system in the edifice at Mount Rainier consists of meteoric water reservoirs, which receive gas and steam from an underlying magmatic system. At present the magmatic system is largely flooded by the meteoric water system. However, magmatic components have episodically vented at the surface as witnessed by the mineralogy of incrustations around inactive vents and gas compositions in the active fumaroles. The composition of fumarole gases during magmatic degassing is distinct and, if sustained, could be lethal. The extent to which hydrothermal alteration is currently occurring at depth, and its possible influence on future edifice collapse, may be determined with the aid of on site analyses of fumarole gases and seismic monitoring in the ice caves.

  2. Reading carbonate deposits from ancient water installations: why are they useful for geoarchaeology?

    NASA Astrophysics Data System (ADS)

    Sürmelihindi, Gül; Passchier, Cees

    2016-04-01

    Water has always been a basic need of life, to remain alive and clean, and to irrigate fertile land, which provides food to people. While looking for a source of water suitable for their requirements, ancient civilizations considered three important factors: to have a reliable supply of water; in sufficient amount and quality; and at affordable costs to transport it to where it was needed. Water lifting and distribution devices were therefore selected and improved with these essential factors in mind. Our understanding of the development of water technology in ancient cultures is mainly based on archaeology and textural sources, focusing on details of the construction of water works and water machines, and on their location in individual settlements. However, the geographic distribution of water technology in Mediterranean and Middle East is poorly understood: both the local economical basis and palaeo-environmental conditions may have played a role in the choice of certain water technologies. As a consequence, some water-lifting devices, e.g. the bucket-chain and Archimedean screw, were only used where favorable conditions prevailed. The use of ancient water installations, however, cannot easily be studied from architectural remains alone: carbonate deposits in and around such installations can provide information, not only on their use but also on palaeo-environmental conditions during their functioning and on local economical conditions. This applies mostly to water installations of Roman or Medieval age. Since the Romans maintained their water technologies routinely, any thick carbonate deposit may give information on periods of economical hardship, too. Carbonate deposits (calcareous sinter) are presently mainly used to study palaeo-environmental changes from Roman aqueducts, but water lifting machines and water mills, which are commonly build of wood, can also be studied in this way. The Romans were the first to apply waterpower to several industrial applications, but little is known about their use. For example, did Roman water-powered flour mills operate continuously, or was their use interrupted because of water scarcity or decline in the Roman economy? Carbonate was deposited in the water channels that fed and drained these machines, and on the wood of the machines themselves. Theoretically, it should therefore be possible to see the frequency of use of the machines from the stable isotope cyclicity and other data stored in carbonate deposits. We are presently applying this technique to incrustations from the Barbegal watermill complex near Arles, France. Carbonate deposits can therefore act as archives that provide us an understanding of palaeo-environmental and economic changes over the last two thousand years and provide information on the use, distribution and age of water structures by means of annual lamina counting. With this great potential, we aim to generate new tools and techniques to study the history of science in the framework of geo-archaeology.

  3. Issues facing the Australian Health Technology Assessment Review of medical technology funding.

    PubMed

    O'Malley, Susanne P

    2010-07-05

    The Australian Health Technology Assessment Review has the potential to have a major effect on the availability of new medical technology and the listing of associated medical procedures on the Medicare Benefits Schedule. Despite this, only about 15% of submissions to the Review came from "medical associations". Pharmaceutical and medical technologies are inherently different, and there are a number of difficulties associated with evaluating medical technology using the same process and evidence levels as those used for pharmaceuticals. The current sequential and lengthy processing of new medical technology and procedures is delaying access to beneficial medical technology and could be substantially reduced. There is currently no effective funding process for medical technology classified as capital equipment or consumables and disposables. This has created a perverse incentive in favour of using funded implantable prostheses based on access to funding rather than superior clinical effectiveness. The existing horizon scanning process could be better used to not only identify all potentially cost-effective new and emerging medical technology and procedures as early as possible, but also to identify gaps in the evidence.

    2001-02-01

    This paper reports on a two-year classroom investigation of primary school (Years 1-8) technology education. The first year of the project explored emerging classroom practices in technology. In the second year intervention strategies were developed to enhance teaching, learning and assessment practices. Findings from the first year revealed that assessment was often seen in terms of social and managerial aspects, such as teamwork, turn taking and co-operative skills, rather than procedural and conceptual technological aspects. Existing formative interactions with students distorted the learning away from the procedural and conceptual aspects of the subject. The second year explored the development of teachers' technological knowledge in order to enhance formative assessment practices in technology, to inform classroom practice in technology, and to enhance student learning. Intervention strategies were designed to enhance the development of procedural, conceptual, societal and technical aspects of technology for teachers and students. The results from this intervention were very positive. This paper highlights the importance of developing teacher expertise pertaining to broad concepts of technology, detailed concepts in different technological areas and general pedagogical knowledge. The findings from this research therefore have implications for thinking about teaching, learning and assessment in technology.

    There is a need to determine if organizations working with health information technology are aware of technology-induced errors and how they are addressing and preventing them. The purpose of this study was to: a) determine the degree of technology-induced error awareness in various Canadian healthcare organizations, and b) identify those processes and procedures that are currently in place to help address, manage, and prevent technology-induced errors. We identified a lack of technology-induced error awareness among participants. Participants identified there was a lack of well-defined procedures in place for reporting technology-induced errors, addressing them when they arise, and preventing them.

This is in part the result of the technical limitations in today's standard laparoscopy, and the advanced surgical skills that are required. Robotic technology overcomes some of these limitations by successfully providing intuitive motion and enhanced precision and accuracy, in an environment that is much more ergonomic. While currently performed in only few designated centers, this technology has already been applied in almost every major procedure performed to treat both benign and malignant conditions of the large bowel. The feasibility of performing these procedures using robotic systems has been reported in several series. Conversion and complication rates are low, and short term results are comparable to conventional laparoscopy. However, no clear advantages to patients have been demonstrated yet. Furthermore, robotic technology is associated with a significant increase in time consumed during surgery and cost of care. Nevertheless, a great potential for patients benefit in the future may exist with this technology. Increasing clinical experience with these systems, further technological developments, and continuous research are required before robotic technology can be routinely incorporated into surgical procedures on the colon and rectum.

  12. State-of-the-art and emerging technologies for atrial fibrillation ablation.

    PubMed

    2010-03-01

    Catheter ablation is an important treatment modality for patients with atrial fibrillation (AF). Although the superiority of catheter ablation over antiarrhythmic drug therapy has been demonstrated in middle-aged patients with paroxysmal AF, the role the procedure in other patient subgroups-particularly those with long-standing persistent AF-has not been well defined. Furthermore, although AF ablation can be performed with reasonable efficacy and safety by experienced operators, long-term success rates for single procedures are suboptimal. Fortunately, extensive ongoing research will improve our understanding of the mechanisms of AF, and considerable funds are being invested in developing new ablation technologies to improve patient outcomes. These technologies include ablation catheters designed to electrically isolate the pulmonary veins with improved safety, efficacy, and speed, catheters designed to deliver radiofrequency energy with improved precision, robotic systems to address the technological demands of the procedure, improved imaging and electrical mapping systems, and MRI-guided ablation strategies. The tools, technologies, and techniques that will ultimately stand the test of time and become the standard approach to AF ablation in the future remain unclear. However, technological advances are sure to result in the necessary improvements in the safety and efficacy of AF ablation procedures.

  18. Cost drivers in total hip arthroplasty: effects of procedure volume and implant selling price.

    PubMed

    Kelly, Michael P; Bozic, Kevin J

    2009-01-01

    Total hip arthroplasty (THA), though a highly effective procedure for patients with end-stage hip disease, has become increasingly costly, both because of increasing procedure volume and because of the introduction and widespread use of new technologies. Data regarding procedure volume and procedure costs for THA were obtained from the National Inpatient Sample and other published sources for the years 1995 through 2005. Procedure volume increased 61% over the period studied. When adjusted for inflation, using the medical consumer price index, the average selling price of THA implants increased 24%. The selling price of THA implants as a percentage of total procedure costs increased from 29% to 60% during the period under study. The increasing cost of THA in the United States is a result of both increased procedure volume and increased cost of THA implants. No long-term outcome studies related to use of new implant technologies are available, and short-term results have been similar to those obtained with previous generations of THA implants. This study reinforces the need for a US total joint arthroplasty registry and for careful clinical and economic analyses of new technologies in orthopedics.

    2005-01-01

    Computer-aided surgical navigation technology is commonly used in craniomaxillofacial surgery. It offers substantial improvement regarding esthetic and functional aspects in a range of surgical procedures. Based on augmented reality principles, where the real operative site is merged with computer generated graphic information, computer-aided navigation systems were employed, among other procedures, in dental implantology, arthroscopy of the temporomandibular joint, osteotomies, distraction osteogenesis, image guided biopsies and removals of foreign bodies. The decision to perform a procedure with or without computer-aided intraoperative navigation depends on the expected benefit to the procedure as well as on the technical expenditure necessary to achieve that goal. This paper comprises the experience gained in 12 years of research, development and routine clinical application. One hundred and fifty-eight operations with successful application of surgical navigation technology--divided into five groups--are evaluated regarding the criteria "medical benefit" and "technical expenditure" necessary to perform these procedures. Our results indicate that the medical benefit is likely to outweight the expenditure of technology with few exceptions (calvaria transplant, resection of the temporal bone, reconstruction of the orbital floor). Especially in dental implantology, specialized software reduces time and additional costs necessary to plan and perform procedures with computer-aided surgical navigation.

    Ikhsan, Mohammad; Tan, Kok Kiong; Putra, Andi Sudjana

    2018-01-01

    This study evaluated the existing technology used to improve the safety and ease of ultrasound-guided central venous catheterization. Electronic database searches were conducted in Scopus, IEEE, Google Patents, and relevant conference databases (SPIE, MICCAI, and IEEE conferences) for related articles on assistive technology for ultrasound-guided central venous catheterization. A total of 89 articles were examined and pointed to several fields that are currently the focus of improvements to ultrasound-guided procedures. These include improving needle visualization, needle guides and localization technology, image processing algorithms to enhance and segment important features within the ultrasound image, robotic assistance using probe-mounted manipulators, and improving procedure ergonomics through in situ projections of important information. Probe-mounted robotic manipulators provide a promising avenue for assistive technology developed for freehand ultrasound-guided percutaneous procedures. However, there is currently a lack of clinical trials to validate the effectiveness of these devices.

  11. A CHARACEAN THALLUS WITH ATTACHED GYROGONITES AND ASSOCIATED FOSSIL CHAROPHYTES FROM THE MAASTRICHTIAN OF THE EASTERN PYRENEES (CATALONIA, SPAIN)(1).

    PubMed

    Villalba-Breva, Sheila; Martín-Closas, Carles

    2011-02-01

    The new species Clavatoraxis microcharophorus is described from the Lower Maastrichtian of the Eastern Pyrenees (Catalonia, Spain). Microchara sp. gyrogonites were found in anatomical connection with this thallus, attached to bract-cell rosettes and coated by a structural tunica, formed by an expanded bract cell. This is a feature unknown in extant characeans, which only display lime incrustations similar to tunicae in extremely alkaline and well-illuminated environments. This is the first time that a complete fossil characean is described. The attribution of characean vegetative remains to the genus Clavatoraxis shows that this genus is not exclusive of clavatoraceans as previously thought. The taphonomic study of C. microcharophorus sp. nov. and associated fossil charophytes, along with sedimentological and microfacies analyses, has enabled us to characterize the habitat of this species in the Maastrichtian lake of Vallcebre. They grew forming meadows, and their remains were deposited in the poorly oxygenated lake bottom, where they were well preserved. A number of other characeans and porocharaceans were living in shallower belts. This was the case for Peckichara sp. and Munieria grambasti in the freshwater lacustrine meadows. Another species, Feistiella malladae, was found parautochthonous in brackish lakes. © 2011 Phycological Society of America.

  15. Beyond volume: hospital-based healthcare technology as a predictor of mortality for cardiovascular patients in Korea.

    PubMed

    Kim, Jae-Hyun; Lee, Yunhwan; Park, Eun-Cheol

    2016-06-01

    To examine whether hospital-based healthcare technology is related to 30-day postoperative mortality rates after adjusting for hospital volume of cardiovascular surgical procedures.This study used the National Health Insurance Service-Cohort Sample Database from 2002 to 2013, which was released by the Korean National Health Insurance Service. A total of 11,109 cardiovascular surgical procedure patients were analyzed. The primary analysis was based on logistic regression models to examine our hypothesis.After adjusting for hospital volume of cardiovascular surgical procedures as well as for all other confounders, the odds ratio (OR) of 30-day mortality in low healthcare technology hospitals was 1.567-times higher (95% confidence interval [CI] = 1.069-2.297) than in those with high healthcare technology. We also found that, overall, cardiovascular surgical patients treated in low healthcare technology hospitals, regardless of the extent of cardiovascular surgical procedures, had the highest 30-day mortality rate.Although the results of our study provide scientific evidence for a hospital volume-mortality relationship in cardiovascular surgical patients, the independent effect of hospital-based healthcare technology is strong, resulting in a lower mortality rate. As hospital characteristics such as clinical pathways and protocols are likely to also play an important role in mortality, further research is required to explore their respective contributions.

    To identify, quantify, and compare total facility costs for 2 breast biopsy methods: vacuum-assisted biopsy (VAB) and needle-wire-localized open surgical biopsy (OSB). A time-and-motion study was done to identify unit resources used in both procedures. Costs were imputed from published literature to value resources. A comparison of the total (fixed and variable) costs of the 2 procedures was done. A convenience sample of 2 high-volume breast biopsy (both VAB and OSB) facilities was identified. A third facility (OSB only) and 8 other sites (VAB only) were used to capture variation. Staff interviews, patient medical records, and billing data were used to check observed data. One hundred and sixty-seven uncomplicated procedures (71 OSBs, 96 VABs) were observed. Available demographic and clinical data were analyzed to assess selection bias, and sensitivity analyses were done on the main assumptions. The total facility costs of the VAB procedure were lower than the costs of the OSB procedure. The overall cost advantage for using VAB ranges from $314 to $843 per procedure depending on the facility type. Variable cost comparison indicated little difference between the 2 procedures. The largest fixed cost difference was $763. Facilities must consider the cost of new technology, especially when the new technology is as effective as the present technology. The seemingly high cost of equipment might negatively influence a decision to adopt VAB, but when total facility costs were analyzed, the new technology was less costly.

    Scanning, also called digitizing, is the process of gathering the requisite data from an object. Many different technologies are used to collect three dimensional data. They range from mechanical and very slow, to radiation-based and highly-automated. Each technology has its advantages and disadvantages, and their applications and specifications overlap. The aims of this study are represented by establishing a viable method of digitally representing artifacts of dental casts, proposing a suitable scanner and post-processing software and obtaining 3D Models for the dental applications. The method is represented by the scanning procedure made by different scanners as the implicated materials. Scanners are the medium of data capture. 3D scanners aim to measure and record the relative distance between the object's surface and a known point in space. This geometric data is represented in the form of point cloud data. The contact and no contact scanners were presented. The results show that contact scanning procedures uses a touch probe to record the relative position of points on the objects' surface. This procedure is commonly used in Reverse engineering applications. Its merits are represented by efficiency for objects with low geometric surface detail. Disadvantages are represented by time consuming, this procedure being impractical for artifacts digitization. The non contact scanning procedure implies laser scanning (laser triangulation technology) and photogrammetry. As a conclusion it can be drawn that different types of dental structure needs different types of scanning procedures in order to obtain a competitive complex 3D virtual model that can be used in CAD/CAM technologies.

  18. Calcium carbonate crystallizations on hypogean mural paintings: a pilot study of monitoring and diagnostics in Roman catacombs

    One of the deterioration processes affecting mural paintings and rock surfaces within manmade hypogea consists in the formation of calcium carbonate crystallizations, which can create thick coverage and incrustations, even in some cases speleothems. These chemical reactions necessarily require the availability of calcium sources, which can be also of anthropogenic origin (e.g., lime-based mortars). Microclimate parameters also represent environmental forcing factors, on which the morphology and the degree of crystallinity of the precipitated carbonates depend. Understanding past/recent dynamics of carbonate precipitation implies a deep knowledge of the relationships between the exposed surfaces and the microclimate conditions, the impacts of external factors (e.g., groundwater infiltration and percolation from the overlying soil) and how they change over time. This is particularly fundamental for the preservation of hypogean sites which have not comparison with other typologies of environment due to their uniqueness, such as the ancient catacombs carved underneath the suburbs of Rome (Italy), since the 2nd century AD. In this paper we present the multidisciplinary methodological approach designed for the instrumental monitoring of the microphysical environment of the Catacombs of Saints Mark, Marcellian and Damasus, in the framework of the co-operation between the Institute for the Conservation and Valorization of Cultural Heritage and Pontifical Commission for Sacred Archaeology, Vatican, on the project HYPOGEA. Temperature inside the catacomb and on the surfaces, air relative humidity and CO2 concentration are the main of the parameters continuously measured by means of data loggers installed within the cubicles. Contemporarily, standardized methods of photographic documentation and digital micro-photogrammetry are used for change detection analysis of the painted surfaces and ancient plasters, as well as of the test areas purposely realized by applying fresh lime mortars simulating the former surfaces. Parallel laboratory investigations (e.g., diamond anvil cell FT-IR spectroscopy, X-ray diffraction, thin section observations under polarized light microscope, conventional microbiological investigations) are complementarily employed to characterize the calcite crystallizations, in terms of compositional, textural and mineralogical properties. Hence, it is expected to find a correlation between the microclimate conditions and the degree of crystallinity and morphology of the incrustations developed on the surfaces of the fresh samples. A specific study of the stratigraphic sequence of the calcite crystallizations already formed on the ancient surfaces is also included, to perform a back-analysis of the microclimate variations inside the cubicles through centuries of use and abandonment. In this regard, the precise knowledge of the conservation history of the monitored cubicles is adopted as a temporal guide to hypothesize the time frames, to which the observed strata are presumably to be referred. The main outcome of this pilot study is the establishment of a methodological approach suitable for the monitoring of crystallization phenomena inside catacombs, to be potentially exported to similar contexts. The findings of the research will also constitute the scientific base for the design of the most appropriate measures of environmental conditioning, also in the perspective to open the catacombs to visitors.

    2016-01-01

    Because of the remarkable developments in robotics in recent years, technological convergence has been active in this area. We focused on finding patterns of convergence within robot technology using network analysis of patents in both the USPTO and KIPO. To identify the variables that affect convergence, we used quadratic assignment procedures (QAP). From our analysis, we observed the patent network ecology related to convergence and found technologies that have great potential to converge with other robotics technologies. The results of our study are expected to contribute to setting up convergence based R&D policies for robotics, which can lead new innovation. PMID:27764196

    PubMed

    Klibansky, David; Rothstein, Richard I

    2012-09-01

    The increasing complexity of intralumenal and emerging translumenal endoscopic procedures has created an opportunity to apply robotics in endoscopy. Computer-assisted or direct-drive robotic technology allows the triangulation of flexible tools through telemanipulation. The creation of new flexible operative platforms, along with other emerging technology such as nanobots and steerable capsules, can be transformational for endoscopic procedures. In this review, we cover some background information on the use of robotics in surgery and endoscopy, and review the emerging literature on platforms, capsules, and mini-robotic units. The development of techniques in advanced intralumenal endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and translumenal endoscopic procedures (NOTES) has generated a number of novel platforms, flexible tools, and devices that can apply robotic principles to endoscopy. The development of a fully flexible endoscopic surgical toolkit will enable increasingly advanced procedures to be performed through natural orifices. The application of platforms and new flexible tools to the areas of advanced endoscopy and NOTES heralds the opportunity to employ useful robotic technology. Following the examples of the utility of robotics from the field of laparoscopic surgery, we can anticipate the emerging role of robotic technology in endoscopy.

  9. Support for the Development of Technological Innovations: Promoting Responsible Social Uses.

    Legault, Georges A; Verchère, Céline; Patenaude, Johane

    2018-04-01

    How can technological development, economic development, and the claims from society be reconciled? How should responsible innovation be promoted? The "responsible social uses" approach proposed here was devised with these considerations in view. In this article, a support procedure for promoting responsible social uses (RSU) is set out and presented. First, the context in which this procedure emerged, which incorporates features of both the user-experience approach and that of ethical acceptability in technological development, is specified. Next, the characteristic features of the procedure are presented, that is, its purpose, fundamental orientation, and component parts as experimented by partners.

    Many new techniques and bariatric endoluminal procedures are being developed and used for the treatment of obesity. Clear guidelines or opinions of the new techniques are not readily available. The aim of this study was to gauge the level of interest and opinions of bariatric surgeons regarding these new techniques, using online and real poll surveys. The American Society for Metabolic and Bariatric Surgery (ASMBS) Emerging Technologies committee developed a questionnaire that was distributed among the membership and conducted a live poll of attendees at Obesity Week 2013. Opinions of new technologies and techniques by practitioners were assessed. A total of 134 responses to the questionnaire were returned. Most responses (79%) expressed the belief that new bariatric techniques are needed to improve the practice of bariatric and metabolic surgery. The responses describing the effects of new procedures and technology as beneficial were (1) increased interest from patients or referring physicians (94%), (2) expanded indications for intervention (93%), and (3) lower risk intervention (96%). Nearly all respondents (90.2%) identified value in informational guidelines on new technologies and procedures, and most (88.7%) agreed that the ASMBS should coordinate clinical trials or registries to evaluate these therapies. Although most bariatric and metabolic surgeons agree that new endoluminal surgical techniques are beneficial, most also are unable to offer the procedures to their patients without more clinical evidence and clear guidelines from the society.

    There is evidence that some geographic variations in the use of medical technologies are not explained by differences in disease burden. The objectives of this study were to quantify variability in the use of percutaneous coronary intervention (PCI), implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) in Spanish autonomous regions and to try to explain the variability found for the first two technologies. Linear regression models were developed in which the number of procedures performed per million population (pmp) in 2003 in each autonomous region was the dependent variable. Independent variables used included indices of technology provision, regional wealth, and disease burden. For PCI, the mean utilization rate for the whole of Spain was 1038 procedures pmp, with a high-low ratio of 1.95. Differences in gross domestic product explained 21% of the variability, but there was no relationship between the number of procedures performed and disease burden. For ICDs, the mean number of procedures performed in the whole of Spain was 46 pmp, with a high-low ratio of 3.04. As for PCI, differences in regional wealth explained 40% of the variability, with disease burden making no contribution. For CRT, the mean number of procedures performed in Spain in 2003 was 15 pmp, with a high-low ratio of 15.7. The considerable regional variation that exists in the use of these three medical technologies is principally explained by differences in regional wealth and not in disease burden.

    Contextual data and local expertise are important sources of data that cannot be ignored in hospital-based health technology assessment (HTA) processes. Despite a lack of or unconvincing evidence in the scientific literature, technology can be recommended in a given context. We illustrate this using a case study regarding biplane angiography for vascular neurointervention. A systematic literature review was conducted, along with an analysis of the context in our setting. The outcomes of interest were radiation doses, clinical complications, procedure times, purchase cost, impact on teaching program, the confidence of clinicians in the technology, quality of care, accessibility, and the volume of activity. A committee comprising managers, clinical experts, physicians, physicists and HTA experts was created to produce a recommendation regarding biplane technology acquisition to replace a monoplane device. The systematic literature review yielded nine eligible articles for analysis. Despite a very low level of evidence in the literature, the biplane system appears to reduce ionizing radiation and medical complications, as well as shorten procedure time. Contextual data indicated that the biplane system could improve operator confidence, which could translate into reduced risk, particularly for complex procedures. In addition, the biplane system can support our institution in its advanced procedures teaching program. Given the advantages provided by the biplane technology in our setting, the committee has recommended its acquisition. Contextual data were of utmost importance in this recommendation. Moreover, this technology should be implemented alongside a responsibility to collect outcome data to optimize clinical protocol in the doses of ionizing delivered.

  3. OCT assisted identification of the grade of encrustation of urologic catheters

    Sroka, Ronald; Püls, Michaela; Stepp, Herbert; Zilinberg, Katja; Bader, Markus; Weidlich, Patrick

    2013-06-01

    Introduction: Ureteric stenting is a commonly used endourologic procedure for temporary and long-term drainage of an obstructed upper urinary tract. The indication for ureteric stenting is obstruction due to intrinsic (intraureteral stones, strictures, or tumors) or extrinsic (for example compressing pelvic or retroperitoneal mass) causes. Despite the fact that stents do certainly have proven benefits in all fields of urology, there are potential morbidities. The most common problem of indwelling ureteral stents is infection. As foreign body in the urinary system, stents act as a nidus for bacteria colonization, crystallization and encrustation. Bacteria induced biofilm formation predisposes for the crystallization of lithogenic salts, such as calcium-phosphate, calcium-oxalate, magnesium-phosphate on the surface initiating stent encrustation. It was the objective of this study to evaluate whether optical coherence tomography (OCT) using both the surface and the endoluminal technique is feasible to investigate the locations and degree of encrustation process in clinically used ureteral stents. Patients and methods: After removal from patients, fourteen polyurethane JJ stents were investigated. A fresh JJ served as a control. The external surfaces were examined using an endoscopic surface OCT whereas the intraluminal surfaces were investigated by an endoluminal radial OCT device. The focus was on detection of encrustation or crystalline sedimentation. Results: In 12 female and 2 male patients, the median indwelling time of the ureteral catheter was 100 days (range 19- 217). Using the endoluminal OCT, the size and grade of intraluminal encrustation could be expressed as a percentage relating to the open lumen of the reference stent. The maximum encrustation observed resulted in a remaining unrestricted lumen of 15-35% compared to the reference. The luminal reduction caused by encrustation was significantly higher at the proximal end of the ureteral stent as compared to its distal part. The extraluminal OCT-investigations facilitated the characterization of extraluminal encrustation. Conclusion: OCT techniques were feasible and facilitated the detection of encrustation of double pigtail catheters on both the extra and intra luminal surface. Quantitative expression of the degree of intraluminal encrustation could be achieved, with the most dense and thickened occurrence of intraluminal incrustation in the upper curl of the JJ stent.

    2017-01-01

    Our purpose is to present a broad review about the principles, early history, evolution, applications, and complications of femtosecond lasers used in refractive and nonrefractive corneal surgical procedures. Femtosecond laser technology added not only safety, precision, and reproducibility to established corneal surgical procedures such as laser in situ keratomileusis (LASIK) and astigmatic keratotomy, but it also introduced new promising concepts such as the intrastromal lenticule procedures with refractive lenticule extraction (ReLEx). Over time, the refinements in laser optics and the overall design of femtosecond laser platforms led to it becoming an essential tool for corneal surgeons. In conclusion, femtosecond laser is a heavily utilized tool in refractive and nonrefractive corneal surgical procedures, and further technological advances are likely to expand its applications.

    2015-01-01

    NASA's Air Traffic Management Technology Demonstration-1 (ATD-1) will operationally demonstrate the feasibility of efficient arrival operations combining ground-based and airborne NASA technologies. The ATD-1 integrated system consists of the Traffic Management Advisor with Terminal Metering which generates precise time-based schedules to the runway and merge points; Controller Managed Spacing decision support tools which provide controllers with speed advisories and other information needed to meet the schedule; and Flight deck-based Interval Management avionics and procedures which allow flight crews to adjust their speed to achieve precise relative spacing. Initial studies identified air-ground challenges related to the integration of these three scheduling and spacing technologies, and NASA's airborne spacing algorithm was modified to address some of these challenges. The Research and Procedural Testing of Routes human-in-the-loop experiment was then conducted to assess the performance of the new spacing algorithm. The results of this experiment indicate that the algorithm performed as designed, and the pilot participants found the airborne spacing concept, air-ground procedures, and crew interface to be acceptable. However, the researchers concluded that the data revealed issues with the frequency of speed changes and speed reversals.

  12. Barcode identification for transfusion safety.

    PubMed

    Murphy, M F; Kay, J D S

    2004-09-01

    Errors related to blood transfusion in hospitals may produce catastrophic consequences. This review addresses potential solutions to prevent patient misidentification including the use of new technology, such as barcoding. A small number of studies using new technology for the transfusion process in hospitals have shown promising results in preventing errors. The studies demonstrated improved transfusion safety and staff preference for new technology such as bedside handheld scanners to carry out pretransfusion bedside checking. They also highlighted the need for considerable efforts in the training of staff in the new procedures before their successful implementation. Improvements in hospital transfusion safety are a top priority for transfusion medicine, and will depend on a combined approach including a better understanding of the causes of errors, a reduction in the complexity of routine procedures taking advantage of new technology, improved staff training, and regular monitoring of practice. The use of new technology to improve the safety of transfusion is very promising. Further development of the systems is needed to enable staff to carry out bedside transfusion procedures quickly and accurately, and to increase their functionality to justify the cost of their wider implementation.

  13. Robotics in general thoracic surgery procedures.

    Latif, M Jawad; Park, Bernard J

    2017-01-01

    The use of robotic technology in general thoracic surgical practice continues to expand across various institutions and at this point many major common thoracic surgical procedures have been successfully performed by general thoracic surgeons using the robotic technology. These procedures include lung resections, excision of mediastinal masses, esophagectomy and reconstruction for malignant and benign esophageal pathologies. The success of robotic technology can be attributed to highly magnified 3-D visualization, dexterity afforded by 7 degrees of freedom that allow difficult dissections in narrow fields and the ease of reproducibility once the initial set up and instruments become familiar to the surgeon. As the application of robotic technology trickle downs from major academic centers to community hospitals, it becomes imperative that its role, limitations, learning curve and financial impact are understood by the novice robotic surgeon. In this article, we share our experience as it relates to the setup, common pitfalls and long term results for more commonly performed robotic assisted lung and thymic resections using the 4 arm da Vinci Xi robotic platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA) to help guide those who are interested in adopting this technology.

    UV radiation as an evolutionarily important environmental factor, significantly affects plants traits and alters the effects of other environmental factors. Single and combined effects of ambient UV radiation, its exclusion, and Se foliar treatments on Si concentrations and production of Si phytoliths in wheat (Triticum aestivum L.) cv. 'Reska' were studied. The effects of these treatments on growth parameters of the plants, structural and biochemical traits of the leaves, and interactions of the leaves with light, as Si incrustation is the first barrier to light at the leaf surface were also examined. Under ambient UV radiation and foliar treatment with 10mgL -1 sodium selenate solution, there was a trade-off between the plant investment in primary and secondary metabolism, as the production of UV-absorbing compounds was enhanced while photosynthetic pigment levels were reduced. Independent of Se treatment, ambient UV radiation lowered respiratory potential, Ca concentration, and leaf thickness, and increased Si concentration, Si phytoliths formation, and cuticle thickness. The Se treatment has little effect on plant traits and biomass production but it increased Se concentrations in the plants by >100-fold, independent of UV radiation. In combination with UV radiation Se strengthen the protection of plants against stress by increasing the amount of UV absorbing compounds, light reflectance and transmittance.

    Ulmer, Brenda C

    2010-05-01

    Techniques and instrumentation for minimally invasive surgical procedures originated in gynecologic surgery, but the benefits of surgery with small incisions or no incisions at all have prompted the expansion of these techniques into numerous specialties. Technologies such as robotic assistance, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and video-assisted thoracoscopic surgery have led to the continued expansion of minimally invasive surgery into new specialties. With this expansion, perioperative nurses and other members of the surgical team are required to continue to learn about new technology and instrumentation, as well as the techniques and challenges involved in using new technology, to help ensure the safety of their patients. This article explores the development of minimally invasive procedures and offers suggestions for increasing patient safety. Copyright 2010 AORN, Inc. Published by Elsevier Inc. All rights reserved.

    2014-06-01

    With the use of electromagnetic navigational bronchoscopy and robotics, lung lesions can be diagnosed and resected during one surgical procedure. Global positioning system technology allows surgeons to identify and mark a thoracic tumor, and then robotics technology allows them to perform minimally invasive resection and cancer staging procedures. Nurses on the perioperative robotics team must consider the logistics of providing safe and competent care when performing combined procedures during one surgical encounter. Instrumentation, OR organization and room setup, and patient positioning are important factors to consider to complete the procedure systematically and efficiently. This revolutionary concept of combining navigational bronchoscopy with robotics requires a team of dedicated nurses to facilitate the sequence of events essential for providing optimal patient outcomes in highly advanced surgical procedures.

  13. MR-guided focused ultrasound: a potentially disruptive technology.

    PubMed

    Bradley, William G

    2009-07-01

    A disruptive technology is a technological innovation that overturns the existing dominant technologies in a market. Magnetic resonance (MR)-guided focused ultrasound (MRgFUS) is a noninvasive procedure based on the combination of real-time MR anatomic guidance, MR thermometry, and high-intensity focused ultrasound. Several hundred transducer elements become convergent at a point under MR guidance, leading to heating and coagulation necrosis. Outside the focal point, there is no significant heating. There is no need to break the skin for procedures in the body or to perform a craniotomy for procedures in the brain. This lack of invasiveness is what makes MRgFUS so disruptive compared with surgery. At present, MRgFUS has been used for the ablation of uterine fibroids, breast tumors, painful bony metastases, and liver tumors. In the brain, it has been used for the ablation of glioblastomas and for functional neurosurgery. Phantom and animal studies suggest future applications for prostate cancer and acute stroke treatment.

  14. Deep Needle Procedures: Improving Safety With Ultrasound Visualization

    Abstract Promoting patient safety and increasing health care quality have dominated the health care landscape during the last 15 years. Health care regulators and payers are now tying patient safety outcomes and best practices to hospital reimbursement. Many health care leaders are searching for new technologies that not only make health care for patients safer but also reduce overall health care costs. New advances in ultrasonography have made this technology available to health care providers at the patient’s bedside. Point-of-care ultrasound assistance now aids providers with real-time diagnosis and with visualization for procedural guidance. This is especially true for common deep needle procedures such as central venous catheter insertion, thoracentesis, and paracentesis. There is now mounting evidence that clinician-performed point-of-care ultrasound improves patient safety, enhances health care quality, and reduces health care cost for deep needle procedures. Furthermore, the miniaturization, ease of use, and the evolving affordability of ultrasound have now made this technology widely available. The adoption of point-of-care ultrasonography has reached a tipping point and should be seriously considered the safety standard for all hospital-based deep needle procedures. PMID:24786918

    Gaitan, Sergio; Markus, Ramsey

    2012-01-01

    Laser resurfacing technology offers the ability to treat skin changes that are the result of the aging process. One of the major drawbacks of laser resurfacing technologies is the pain associated with the procedure. The methods of anesthesia used in laser resurfacing to help minimize the pain include both noninvasive and invasive procedures. The noninvasive procedures can be divided into topical, cryoanesthesia, and a combination of both. The invasive methods of anesthesia include injected forms (infiltrative, nerve blocks, and tumescent anesthesia) and supervised anesthesia (monitored anesthesia care and general anesthesia). In this review, the authors summarize the types of anesthesia used in laser resurfacing to aid the provider in offering the most appropriate method for the patient to have as painless a procedure as possible.

    Our goal is to apply robotics and automation technology to assist, enhance, quantify, and document neurorehabilitation. This paper reviews a clinical trial involving 20 stroke patients with a prototype robot-aided rehabilitation facility developed at the Massachusetts Institute of Technology, Cambridge, (MIT) and tested at Burke Rehabilitation Hospital, White Plains, NY. It also presents our approach to analyze kinematic data collected in the robot-aided assessment procedure. In particular, we present evidence 1) that robot-aided therapy does not have adverse effects, 2) that patients tolerate the procedure, and 3) that peripheral manipulation of the impaired limb may influence brain recovery. These results are based on standard clinical assessment procedures. We also present one approach using kinematic data in a robot-aided assessment procedure. PMID:9535526

    To evaluate different technologies that can facilitate telementoring in a variety of pediatric surgical procedures. Two different telementoring technologies were used to provide two-way audio and visual communication between experienced pediatric surgeon mentors located in another city and less experienced trainees performing a surgical procedure. The first technology consisted of store-bought equipment that connected the operating room laparoscope to a Skype™ (Microsoft, Redmond, WA) connection (used in 1 case), whereas the second was a proprietary telementoring robot, Karl Storz Endoscopy-America, Inc. VisitOR1(®) (Karl Storz GmbH & Co. KG, Tuttlingen, Germany) (used in 5 cases). The procedures included a video-assisted thoracic surgery lower lobectomy, a temporary and two permanent gastric stimulator placements, and two laparoscopic inguinal hernia repairs and were performed by pediatric surgeons (3 cases), a pediatric gastroenterologist (1 case), and a general surgeon (2 cases) under the guidance of pediatric surgeon mentors. All procedures were completed successfully in a time-efficient manner, without loss of transmission and without complications. Although the Skype technology was less costly, it lacked telestrator capacity and was not adequately secure. The VisitOR1 telementoring robot enabled high-resolution video communication, had telestrator capacity, and allowed pointing during the procedure. The mentors assisted with trocar placement, modifying the surgical technique, identifying planes of dissection, and indicating locations of device and suture placement. Telementoring is a useful adjunct in the field of pediatric surgery that can aid in the transfer of surgical skills remotely and shorten the time to implementation of new surgical techniques into practice. Optimal telementoring technology should have a secure wireless connection, high video resolution, and minimal bandwidth latency.

  11. Evaluation of Flight Deck-Based Interval Management Crew Procedure Feasibility

    2013-01-01

    Air traffic demand is predicted to increase over the next 20 years, creating a need for new technologies and procedures to support this growth in a safe and efficient manner. The National Aeronautics and Space Administration's (NASA) Air Traffic Management Technology Demonstration - 1 (ATD-1) will operationally demonstrate the feasibility of efficient arrival operations combining ground-based and airborne NASA technologies. The integration of these technologies will increase throughput, reduce delay, conserve fuel, and minimize environmental impacts. The ground-based tools include Traffic Management Advisor with Terminal Metering for precise time-based scheduling and Controller Managed Spacing decision support tools for better managing aircraft delay with speed control. The core airborne technology in ATD-1 is Flight deck-based Interval Management (FIM). FIM tools provide pilots with speed commands calculated using information from Automatic Dependent Surveillance - Broadcast. The precise merging and spacing enabled by FIM avionics and flight crew procedures will reduce excess spacing buffers and result in higher terminal throughput. This paper describes a human-in-the-loop experiment designed to assess the acceptability and feasibility of the ATD-1 procedures used in a voice communications environment. This experiment utilized the ATD-1 integrated system of ground-based and airborne technologies. Pilot participants flew a high-fidelity fixed base simulator equipped with an airborne spacing algorithm and a FIM crew interface. Experiment scenarios involved multiple air traffic flows into the Dallas-Fort Worth Terminal Radar Control airspace. Results indicate that the proposed procedures were feasible for use by flight crews in a voice communications environment. The delivery accuracy at the achieve-by point was within +/- five seconds and the delivery precision was less than five seconds. Furthermore, FIM speed commands occurred at a rate of less than one per minute, and pilots found the frequency of the speed commands to be acceptable at all times throughout the experiment scenarios.

  12. Microrobotics for future gastrointestinal endoscopy.

    Menciassi, Arianna; Quirini, Marco; Dario, Paolo

    2007-01-01

    The impulse given by robotic technologies and imaging techniques to the development of a new way to conceive and perform surgery is clearly visible. Nowadays, minimally invasive surgical (MIS) procedures are often performed with the assistance of robots, such as the Da Vinci master-slave system, the AESOP robot with voice control, etc. In addition, mechatronic technologies are becoming the elective technologies for designing advanced hand-held surgical tools. The introduction of robotic technologies in endoscopy has been slower than in MIS, since the development of miniaturized robotic components for entering the small orifices of the human body is difficult. On the other hand, the large contribution that robotic technologies could bring to endoluminal techniques has been evident since the first development of instrumented catheters. In the 1990s, there was an increasing activity in the application of robotic technologies to improve endoscopic procedures in the gastrointestinal tract. The objective of robotic colonoscopy and gastroscopy was to obtain more effective diagnoses in terms of reduced pain for the patients, and to make uniform the diagnostic procedures, which too often depended on the manual abilities of the endoscopist. Currently, the availability of more reliable robotic technologies for miniaturization of size and integration of functions has allowed to conceive and develop robotic pills for the early screening of the digestive tract, with dramatic potential advantages for patients, endoscopists, and healthcare system.

    To identify and integrate new safety technologies into outpatient musculoskeletal procedures and measure the effect on outcome, including pain. Using national resources for patient safety and literature review, the following safety technologies were identified: a safety needle to reduce inadvertent needlesticks to heath care workers, and the reciprocating procedure device (RPD) to improve patient safety and reduce pain. Five hundred sixty-six musculoskeletal procedures involving syringes and needles were randomized to either an RPD group or a conventional syringe group, and pain, quality, safety, and physician acceptance were measured. During 566 procedures, no accidental needlesticks occurred with safety needles. Use of the RPD resulted in a 35.4% reduction (95% confidence interval [95% CI] 24-46%) in patient-assessed pain (mean +/- SD scores on a visual analog pain scale [VAPS] 3.12 +/- 2.23 for the RPD and 4.83 +/- 3.22 for the conventional syringe; P < 0.001) and a 49.5% reduction (95% CI 34-64%) in patient-assessed significant pain (VAPS score > or =5) (P < 0.001). Physician acceptance of the RPD combined with a safety needle was excellent. As mandated by the Joint Commission and the Occupational Safety and Health Administration, safety technologies and the use of pain scales can be successfully integrated into rheumatologic and orthopedic procedures. The combination of a safety needle to reduce needlestick injuries to health care workers and the RPD to improve safety and outcome of patients is effective and well accepted by physicians.

    2004-03-01

    The Food Safety and Inspection Service (FSIS) has implemented new procedures for meat and poultry establishments, egg products plants, and companies that manufacture and sell technology to official establishments to notify the Agency of new technology that they propose to use in meat and poultry establishments or egg products plants. If the new technology could affect FSIS regulations, product safety, inspection procedures, or the safety of Federal inspection program personnel, then the establishment or plant would need to submit a written protocol to the Agency. As part of this process, the submitter will be expected to conduct in-plant trials of the new technology. The submitter will need to provide data to FSIS throughout the duration of the in-plant trial for the Agency to examine. Data may take several forms: laboratory results, weekly or monthly summary production reports, and evaluations from inspection program personnel.

  9. SU-D-209-03: Radiation Dose Reduction Using Real-Time Image Processing in Interventional Radiology

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Kanal, K; Moirano, J; Zamora, D

    Purpose: To characterize changes in radiation dose after introducing a new real-time image processing technology in interventional radiology systems. Methods: Interventional radiology (IR) procedures are increasingly complex, at times requiring substantial time and radiation dose. The risk of inducing tissue reactions as well as long-term stochastic effects such as radiation-induced cancer is not trivial. To reduce this risk, IR systems are increasingly equipped with dose reduction technologies.Recently, ClarityIQ (Philips Healthcare) technology was installed in our existing neuroradiology IR (NIR) and vascular IR (VIR) suites respectively. ClarityIQ includes real-time image processing that reduces noise/artifacts, enhances images, and sharpens edges while alsomore » reducing radiation dose rates. We reviewed 412 NIR (175 pre- and 237 post-ClarityIQ) procedures and 329 VIR (156 preand 173 post-ClarityIQ) procedures performed at our institution pre- and post-ClarityIQ implementation. NIR procedures were primarily classified as interventional or diagnostic. VIR procedures included drain port, drain placement, tube change, mesenteric, and implanted venous procedures. Air Kerma (AK in units of mGy) was documented for all the cases using a commercial radiation exposure management system. Results: When considering all NIR procedures, median AK decreased from 1194 mGy to 561 mGy. When considering all VIR procedures, median AK decreased from 49 to 14 mGy. Both NIR and VIR exhibited a decrease in AK exceeding 50% after ClarityIQ implementation, a statistically significant (p<0.05) difference. Of the 5 most common VIR procedures, all median AK values decreased, but significance (p<0.05) was only reached in venous access (N=53), angio mesenteric (N=41), and drain placement procedures (N=31). Conclusion: ClarityIQ can reduce dose significantly for both NIR and VIR procedures. Image quality was not assessed in conjunction with the dose reduction.« less

    The introduction of new interventional procedures is less regulated than for other health technologies such as pharmaceuticals. Decisions are often taken on evidence of efficacy and short-term safety from small-scale usually observational studies. This reflects the particular challenges of evaluating interventional procedures - the extra facets of skill and training and the difficulty defining a 'new' technology. Currently, there is no framework to evaluate new interventional procedures before they become available in clinical practice as opposed to new pharmaceuticals. This paper proposes a framework to guide the evaluation of a new interventional procedure. A framework was developed consisting of a four-stage progressive evaluation for a new interventional procedure: Stage 1: Development; Stage 2: Efficacy and short-term safety; Stage 3: Effectiveness and cost-effectiveness; and Stage 4: Implementation. The framework also suggests the types of studies or data collection methods that can be used to satisfy each stage. This paper makes a first step on a framework for generating evidence on new interventional procedures. The difficulties and limitations of applying such a framework are discussed.

    2016-01-01

    The use of assisted reproductive technologies (ART) has increased steadily. There has been a corresponding increase in the number of ART-related procedures such as hysterosalpingography (HSG), saline infusion sonography (SIS), hysteroscopy, laparoscopy, oocyte retrieval, and embryo transfer (ET). While performing these procedures, the abdomen, upper vagina, and endocervix are breached, leading to the possibility of seeding pelvic structures with microorganisms. Antibiotic prophylaxis is therefore important to prevent or treat any procedure-related infections. After careful review of the published literature, it is evident that routine antibiotic prophylaxis is generally not recommended for the majority of ART-related procedures. For transcervical procedures such as HSG, SIS, hysteroscopy, ET, and chromotubation, patients at risk for pelvic infections should be screened and treated prior to the procedure. Patients with a history of pelvic inflammatory disease (PID) or dilated fallopian tubes are at high risk for postprocedural infections and should be given antibiotic prophylaxis during procedures such as HSG, SIS, or chromotubation. Antibiotic prophylaxis is recommended prior to oocyte retrieval in patients with a history of endometriosis, PID, ruptured appendicitis, or multiple prior pelvic surgeries. PMID:27047692

  5. From innovation to standard practice: Developing and disseminating behavioral procedures

    1982-01-01

    This paper proposes a three-stage continuum for discussing the development and dissemination of behavioral technology. At the level of behavioral techniques, researchers need only establish a functional relationship between technologically defined intervention procedures and socially significant target behaviors. Dissemination is conducted for informational purposes only, and the purposes and details surrounding subsequent use of the technique are left to the discretion of the user. At the level of behavioral demonstration, a collection of socially acceptable intervention procedures is refined and standardized and must be shown to produce behavior changes across a number of subjects. Here dissemination is conducted, in large part, to generate support for provision of services. At the level of behavioral models, procedural descriptions must be useroriented. Additionally, model effects must be obtainable by agents not associated with their development and must compare favorably with other treatment or service alternatives. The purpose of dissemination at this level is to obtain adoptions and replications of the model. Details of development and dissemination of behavioral technology at each of these three levels are discussed. PMID:22478555

    New interactive computer technologies are having a significant influence on medical education, training, and practice. The newest innovation in computer technology, virtual reality, allows an individual to be immersed in a dynamic computer-generated, three-dimensional environment and can provide realistic simulations of surgical procedures. A new virtual reality hysteroscope passes through a sensing device that synchronizes movements with a three-dimensional model of a uterus. Force feedback is incorporated into this model, so the user actually experiences the collision of an instrument against the uterine wall or the sensation of the resistance or drag of a resectoscope as it cuts through a myoma in a virtual environment. A variety of intrauterine pathologies and procedures are simulated, including hyperplasia, cancer, resection of a uterine septum, polyp, or myoma, and endometrial ablation. This technology will be incorporated into comprehensive training programs that will objectively assess hand-eye coordination and procedural skills. It is possible that by incorporating virtual reality into hysteroscopic training programs, a decrease in the learning curve and the number of complications presently associated with the procedures may be realized. Prospective studies are required to assess these potential benefits.

    Since the introduction of robotic technology, there have been significant changes to the field of gynecologic oncology. The number of minimally invasive procedures has drastically increased, with robotic procedures rising remarkably. With recent evidence suggesting that minimally invasive techniques should be the standard of care for early endometrial and cervical cancers, the push for new technology and advancements has continued. Several emerging robotic technologies have significant potential in the field of gynecologic oncology. The single-site robotic platform enables robotic surgery through a single incision; the Firefly camera detects the fluorescent dye indocyanine green, which may improve sensitivity in sentinel lymph node biopsy; and a robotic vessel-sealing device and stapler will continue to improve efficiency of the robotic surgeon.

    To address the future performance and safety requirements for the electrical energy storage technologies that will enhance and enable future NASA manned aerospace missions, advanced rechargeable, lithium-ion battery technology development is being pursued within the scope of the NASA Exploration Technology Development Program s (ETDP's) Energy Storage Project. A critical cell-level component of a lithium-ion battery which significantly impacts both overall electrochemical performance and safety is the porous separator that is sandwiched between the two active cell electrodes. To support the selection of the optimal cell separator material(s) for the advanced battery technology and chemistries under development, laboratory characterization and screening procedures were established to assess and compare separator material-level attributes and associated separator performance characteristics.

    Functional neurosurgery has undergone rapid growth over the last few years fueled by advances in imaging technology and novel treatment modalities. These advances have led to new surgical treatments using minimally invasive and precise techniques for conditions such as Parkinson's disease, essential tremor, epilepsy, and psychiatric disorders. Understanding the goals and technological issues of these procedures is imperative for the anesthesiologist to ensure safe management of patients presenting for functional neurosurgical procedures. In this review, we discuss the advances in neurosurgical techniques for deep brain stimulation, focused ultrasound and minimally invasive laser-based treatment of refractory epilepsy and provide a guideline for anesthesiologists caring for patients undergoing these procedures.

    Whole genome sequencing (WGS) shows great potential for real-time monitoring and identification of infectious disease outbreaks. However, rapid and reliable comparison of data generated in multiple laboratories and using multiple technologies is essential. So far studies have focused on using one technology because each technology has a systematic bias making integration of data generated from different platforms difficult. We developed two different procedures for identifying variable sites and inferring phylogenies in WGS data across multiple platforms. The methods were evaluated on three bacterial data sets and sequenced on three different platforms (Illumina, 454, Ion Torrent). We show that the methods are able to overcome the systematic biases caused by the sequencers and infer the expected phylogenies. It is concluded that the cause of the success of these new procedures is due to a validation of all informative sites that are included in the analysis. The procedures are available as web tools.

    Edmonds, Ernest W.; Rowlands, John A.; Hynes, David M.; Toth, B. D.; Porter, Anthony J.

    1990-07-01

    There is increased concern over radiation exposure to the general population from many sources. One of the most significant sources is that received by the patient during medical diagnostic procedures, and of these, the procedure with the greatest potential hazard is fluoroscopy. The legal limit for fluoroscopy in most jurisdictions is SR per minute skin exposure rate. Fluoroscopes are often operated in excess of this figure, and in the case of interventional procedures, fluorocopy times may exceed 20 minutes. With improvements in medical technology these procedures are being performed more often, and also are being carried out on younger age groups. Radiation exposure during fluoroscopy, both to patient and operator, is therefore becoming a matter of increasing concern to regulating authorities, and it is incumbent on us to develop digital technology to minimise the radiation hazard in these procedures. This paper explores the technical options available for radiation exposure reduction, including pulsed fluoroscopy, digital noise reduction, or simple reduction in exposure rate to the x-ray image intensifier. We also discuss educational aspects of fluoroscopy which radiologists should be aware of which can be more important than the technological solutions. A "work in progress" report gives a completely new approach to the implementation of a large number of possible digital algorithms, for the investigation of clinical efficacy.

  9. Rapid Measurement of Soil Carbon in Rice Paddy Field of Lombok Island Indonesia Using Near Infrared Technology

    2018-02-01

    Measuring soil organic carbon (C) using conventional analysis is tedious procedure, time consuming and expensive. It is needed simple procedure which is cheap and saves time. Near infrared technology offers rapid procedure as it works based on the soil spectral reflectance and without any chemicals. The aim of this research is to test whether this technology able to rapidly measure soil organic C in rice paddy field. Soil samples were collected from rice paddy field of Lombok Island Indonesia, and the coordinates of the samples were recorded. Parts of the samples were analysed using conventional analysis (Walkley and Black) and some other parts were scanned using near infrared spectroscopy (NIRS) for soil spectral collection. Partial Least Square Regression (PLSR) Models were developed using data of soil C analysed using conventional analysis and data from soil spectral reflectance. The models were moderately successful to measure soil C in rice paddy field of Lombok Island. This shows that the NIR technology can be further used to monitor the C change in rice paddy soil.

    PubMed

    Green, James; Weiss, Adam; Stern, Avichai

    2011-07-01

    Advances in technology are changing the ways that patients experience dental treatment. Technology helps to decrease treatment time and makes the treatment more comfortable for the patient. One technological advance is the use of lasers in dentistry. Lasers are providing more efficient, more comfortable, and more predictable outcomes for patients. Lasers are used in all aspects of dentistry, including operative, periodontal, endodontic, orthodontic, and oral and maxillofacial surgery. Lasers are used for soft and hard tissue procedures in the treatment of pathologic conditions and for esthetic procedures. This article discusses how lasers work and their application in the various specialties within dentistry. Copyright © 2011 Elsevier Inc. All rights reserved.

  17. The influence of economic incentives and regulatory factors on the adoption of treatment technologies: a case study of technologies used to treat heart attacks.

    PubMed

    Bech, Mickael; Christiansen, Terkel; Dunham, Kelly; Lauridsen, Jørgen; Lyttkens, Carl Hampus; McDonald, Kathryn; McGuire, Alistair

    2009-10-01

    The Technological Change in Health Care Research Network collected unique patient-level data on three procedures for treatment of heart attack patients (catheterization, coronary artery bypass grafts and percutaneous transluminal coronary angioplasty) for 17 countries over a 15-year period to examine the impact of economic and institutional factors on technology adoption. Specific institutional factors are shown to be important to the uptake of these technologies. Health-care systems characterized as public contract systems and reimbursement systems have higher adoption rates than public-integrated health-care systems. Central control of funding of investments is negatively associated with adoption rates and the impact is of the same magnitude as the overall health-care system classification. GDP per capita also has a strong role in initial adoption. The impact of income and institutional characteristics on the utilization rates of the three procedures diminishes over time.

  18. [Impact of digital technology on clinical practices: perspectives from surgery].

    PubMed

    Zhang, Y; Liu, X J

    2016-04-09

    Digital medical technologies or computer aided medical procedures, refer to imaging, 3D reconstruction, virtual design, 3D printing, navigation guided surgery and robotic assisted surgery techniques. These techniques are integrated into conventional surgical procedures to create new clinical protocols that are known as "digital surgical techniques". Conventional health care is characterized by subjective experiences, while digital medical technologies bring quantifiable information, transferable data, repeatable methods and predictable outcomes into clinical practices. Being integrated into clinical practice, digital techniques facilitate surgical care by improving outcomes and reducing risks. Digital techniques are becoming increasingly popular in trauma surgery, orthopedics, neurosurgery, plastic and reconstructive surgery, imaging and anatomic sciences. Robotic assisted surgery is also evolving and being applied in general surgery, cardiovascular surgery and orthopedic surgery. Rapid development of digital medical technologies is changing healthcare and clinical practices. It is therefore important for all clinicians to purposefully adapt to these technologies and improve their clinical outcomes.

  19. Racial and gender variation in use of diagnostic colonic procedures in the Michigan Medicare population.

    1999-07-01

    There is accumulating evidence that screening programs can alter the natural history of colorectal cancer, a significant cause of mortality and morbidity in the US. Understanding how the technology to diagnose colonic diseases is utilized in the population provides insight into both the access and processes of care. Using Medicare Part B billing files from the state of Michigan from 1986 to 1989 we identified all procedures used to diagnose colorectal disease. We utilized the Medicare Beneficiary File and the Area Resource File to identify beneficiary-specific and community-sociodemographic characteristics. The beneficiary and sociodemographic characteristics were, then, used in multiple regression analyses to identify their association with procedure utilization. Sigmoidoscopic use declined dramatically with the increasing age cohorts of Medicare beneficiaries. Urban areas and communities with higher education levels had more sigmoidoscopic use. Among procedures used to examine the entire colon, isolated barium enema was used more frequently in African Americans, the elderly, and females. The combination of barium enema and sigmoidoscopy was used more frequently among females and the newest technology, colonoscopy, was used most frequently among White males. The existence of race, gender, and socioeconomic disparities in the use of colorectal technologies in a group of patients with near-universal insurance coverage demonstrates the necessity of understanding the reason(s) for these observed differences to improve access to appropriate technologies to all segments in our society.

    Ongoing multi-center clinical trials are crucial for Biophotonics to gain acceptance in medical imaging. In these trials, quality control (QC) and assurance (QA) are key to success and provide "data insurance". Quality control and assurance deal with standardization, validation, and compliance of procedures, materials and instrumentation. Specifically, QC/QA involves systematic assessment of testing materials, instrumentation performance, standard operating procedures, data logging, analysis, and reporting. QC and QA are important for FDA accreditation and acceptance by the clinical community. Our Biophotonics research in the Network for Translational Research in Optical Imaging (NTROI) program for breast cancer characterization focuses on QA/QC issues primarily related to the broadband Diffuse Optical Spectroscopy and Imaging (DOS/I) instrumentation, because this is an emerging technology with limited standardized QC/QA in place. In the multi-center trial environment, we implement QA/QC procedures: 1. Standardize and validate calibration standards and procedures. (DOS/I technology requires both frequency domain and spectral calibration procedures using tissue simulating phantoms and reflectance standards, respectively.) 2. Standardize and validate data acquisition, processing and visualization (optimize instrument software-EZDOS; centralize data processing) 3. Monitor, catalog and maintain instrument performance (document performance; modularize maintenance; integrate new technology) 4. Standardize and coordinate trial data entry (from individual sites) into centralized database 5. Monitor, audit and communicate all research procedures (database, teleconferences, training sessions) between participants ensuring "calibration". This manuscript describes our ongoing efforts, successes and challenges implementing these strategies.

  1. Significant Radiation Dose Reduction in the Hybrid Operating Room Using a Novel X-ray Imaging Technology.

    To prospectively quantify radiation dose change in aortoiliac endovascular procedures in the hybrid operating room (OR) for patients and medical staff with a novel X-ray imaging technology (ClarityIQ technology), and to assess whether procedure or fluoroscopy time or dose of iodinated contrast was affected. A prospective study including 138 patients was performed to compare radiation dose before and after installation of a novel X-ray imaging technology. Endovascular aneurysm repair (EVAR) was performed in 37 patients and an endovascular procedure for aortoiliac occlusive disease (AIOD) in 101. Patient radiation dose in air kerma (AK) and dose area product (DAP), patient demographics, and procedural data were recorded. Staff radiation dose was measured with real time personal dosimetry measurements. In both the EVAR and AIOD groups the reference system, ALX (AlluraXper FD20; Philips Healthcare, Best, the Netherlands), was compared with the upgraded X-ray system, CIQ (AlluraClarity FD20; Philips Healthcare). Procedure time, fluoroscopy time, and iodinated contrast dose were recorded. Patient radiation dose reduction in the EVAR group, in median AK, was 56% (ALX = 1,262.5 mGy; CIQ = 556.0 mGy [p < .01]); and in median DAP it was 57% (ALX = 224.4 Gycm(2) and CIQ = 95.8 Gycm(2) [p < .01]). Patient radiation dose reduction in the AIOD group, in median AK, was 76% (ALX = 1,011.0 mGy; CIQ = 248.0 mGy [p < .01]); and in median DAP it was 73% (ALX = 138.1 Gycm(2); CIQ = 38.0 Gycm(2) [p < .01]). Staff dose reduction in the EVAR group was 16% (ALX = 70.1 μSv; CIQ = 59.2 μSv [p = .43]) and in the AIOD group it was 69% (ALX = 96.2 μSv; CIQ = 30.1 μSv [p < .01]). There was no statistically significant difference between patient demographics, procedure time, fluoroscopy time, and iodinated contrast medium use in the two treatment groups before and after installation. A novel X-ray imaging technology in the hybrid OR suite resulted in a significant reduction of patient and staff radiation dose without affecting procedure length, fluoroscopy time, or use of contrast.

  2. Technological hurdles to the application of intercalated graphite fibers

    NASA Technical Reports Server (NTRS)

    Gaier, James R.

    1988-01-01

    Before intercalated graphite fibers can be developed as an effective power material, there are several technological hurdles which must be overcome. These include the environmental stability, homogeneity and bulk properties, connection procedures, and costs. Strides were made within the last several years in stability and homogeneity of intercalated graphite fibers. Bulk properties and connection procedures are areas of active research now. Costs are still prohibitive for all but the most demanding applications. None of these problems, however, appear to be unsolvable, and their solution may result in wide spread GOC application. The development of a relatively simple technology application, such as EMI shielding, would stimulate the solution of scale-up problems. Once this technology is developed, then more demanding applications, such as power bus bars, may be possible.

    North, R.; Lea, W.

    1982-03-01

    This report documents research on the potential use of speech technology in a manned penetration bomber aircraft (B-52/G and H). The objectives of the project were to analyze the pilot/copilot crewstation tasks over a three-hour-and forty-minute mission and determine the tasks that would benefit the most from conversion to speech recognition/generation, determine the technological feasibility of each of the identified tasks, and prioritize these tasks based on these criteria. Secondary objectives of the program were to enunciate research strategies in the application of speech technologies in airborne environments, and develop guidelines for briefing user commands on the potential of using speech technologies in the cockpit. The results of this study indicated that for the B-52 crewmember, speech recognition would be most beneficial for retrieving chart and procedural data that is contained in the flight manuals. Technological feasibility of these tasks indicated that the checklist and procedural retrieval tasks would be highly feasible for a speech recognition system.

  8. A qualitative analysis of the determinants in the choice of a French journal reviewing procedures

    NASA Astrophysics Data System (ADS)

    Morge, Ludovic

    2015-12-01

    Between 1993 and 2010, two French journals (Aster and Didaskalia) coming from different backgrounds but belonging to the same institution used to publish papers on research in science and technology education. The merging of these journals made it necessary for them to compare the different reviewing procedures used by each. This merging occurred at a time when research is becoming increasingly international which partly determines some of the reviewing procedure choices. In order for a francophone international journal to survive, it needs to take this internationalization into account in a reasoned manner. The author of this article, as a chief editor of RDST (Recherches en Didactique des Sciences et des Technologies)—the journal resulting from the merging- taking part in this merger, analyses the social, cultural and pragmatic determinants which impacted the choices made in reviewing procedures. This paper describes how these diversity of factors leads us to drop the idea of a standard reviewing procedure which would be valid for all journals.

  17. Groundwater quality from a part of Prakasam District, Andhra Pradesh, India

    NASA Astrophysics Data System (ADS)

    Subba Rao, N.

    2018-03-01

    Quality of groundwater is assessed from a part of Prakasam district, Andhra Pradesh, India. Groundwater samples collected from thirty locations from the study area were analysed for pH, electrical conductivity (EC), total dissolved solids (TDS), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), bicarbonate ( {HCO}3^{ - } ), chloride (Cl-), sulphate ( {SO}4^{2 - } ), nitrate ( {NO}3^{ - } ) and fluoride (F-). The results of the chemical analysis indicate that the groundwater is alkaline in nature and are mainly characterized by Na+- {HCO}3^{ - } and Na+-Cl- facies. Groundwater chemistry reflects the dominance of rock weathering and is subsequently modified by human activities, which are supported by genetic geochemical evolution and hydrogeochemical relations. Further, the chemical parameters (pH, TDS, Ca2+, Mg2+, Na+, {HCO}3^{ - } , Cl-, {SO}4^{2 - } , {NO}3^{ - } and F-) were compared with the drinking water quality standards. The sodium adsorption ratio, percent sodium, permeability index, residual sodium carbonate, magnesium ratio and Kelly's ratio were computed and USSL, Wilcox and Doneen's diagrams were also used for evaluation of groundwater quality for irrigation. For industrial purpose, the pH, TDS, {HCO}3^{ - } , Cl- and {SO}4^{2 - } were used to assess the impact of incrustation and corrosion activities on metal surfaces. As a whole, it is observed that the groundwater quality is not suitable for drinking, irrigation and industrial purposes due to one or more chemical parameters exceeding their standard limits. Therefore, groundwater management measures were suggested to improve the water quality.

    To evaluate the clinical efficacy of intradermal injection of methylene blue for treatment of moderate to severe acute thoracic herpes zoster and prevention of postherpetica neuralgia in elderly patients. Sixty-four elderly patients with herpes zoster were randomized to receive a 10-day course of intradermal injection of methylene blue and lidocaine plus oral valaciclovir (group A, 32 cases) and intradermal injection of lidocaine plus oral valaciclovir (group B).Herpes evaluation index, pain rating index, incidence of postherpetic neuralgia, and comprehensive therapeutic effect were compared between the two groups at 11, 30 and 60 days after the treatment. The baseline characteristics were comparable between the two groups (all P>0.05). Compared with that in group B, the time for no new blister formation, blister incrustation and decrustation, and pain relief was significantly shortened in group A (P<0.05) with also obviously lower pain intensity after the treatment. The incidence of postherpetic neuralgia was significantly lower in group A than in group B at 30 days (P<0.05), but not at 60 and 90 days after the treatment. The total clinical response rate was 93.8% in group A, much higher than that in group B (62.5%, P<0.05). Intradermal injection of methylene blue can effectively shorten the disease course, reduce the pain intensity and prevent the development of postherpetic neuralgia in elderly patients with herpes zoster.

    Lung nodule evaluation represents a clinical challenge especially in patients with intermediate risk for malignancy. Multiple technologies are presently available to sample nodules for pathological diagnosis. Those technologies can be divided into bronchoscopic and non-bronchoscopic interventions. Electromagnetic navigational bronchoscopy is being extensively used for the endobronchial approach to peripheral lung nodules but has been hindered by anatomic challenges resulting in a 70% diagnostic yield. Electromagnetic navigational guided transthoracic needle lung biopsy is novel non-bronchoscopic method that uses a percutaneous electromagnetic tip tracked needle to obtain core biopsy specimens. Electromagnetic navigational transthoracic needle aspiration complements bronchoscopic techniques potentially allowing the provider to maximize the diagnostic yield during one single procedure. This article describes a novel integrated diagnostic approach to pulmonary lung nodules. We propose the use of endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) for mediastinal staging; radial EBUS, navigational bronchoscopy and E-TTNA during one single procedure to maximize diagnostic yield and minimize the number of invasive procedures needed to obtain a diagnosis. This manuscript describes in detail how the navigation transthoracic procedure is performed. Additional clinical studies are needed to determine the clinical utility of this novel technology.

    2017-08-01

    The implantation of metallic stents has become a standard procedure to improve the outcome after angioplasty of peripheral vessels. However, the occurrence of in-stent restenosis is hampering the long-term efficacy of these procedures and is associated with re-occurrence of symptoms. The optimal treatment modality for in-stent-restenosis in the peripheral vasculature is not well examined. This review discusses the existing evidence for the treatment of in-stent restenosis with drug eluting stents and modern stent technologies.

    Resection of malignancies in the head and uncinate process of the pancreas (Whipple procedure) using a robotic approach is emerging as a surgical option. Although several case series of the robotic Whipple procedure have been reported, detailed descriptions of operative techniques and a clear pathway for adopting this technology are lacking. We present a focused review of the procedure as it applies to pancreatic cancer and describe our clinical pathway for the robotic Whipple procedure used in pancreatic cancer and review the outcomes of our early experience. A systematic review of the literature is provided, focusing on the indications, variations in surgical techniques, complications, and oncological results of the robotic Whipple procedure. A clinical pathway has been defined for preoperative training of surgeons, the requirements for hospital privileges, patient selection, and surgical techniques for the robotic Whipple procedure. The robotic technique for managing malignant lesions of the pancreas head is safe when following well-established guidelines for adopting the technology. Preliminary data demonstrate that perioperative convalescence may exceed end points when compared with the open technique. The robotic Whipple procedure is a minimally invasive approach for select patients as part of multidisciplinary management of periampullary lesions in tertiary centers where clinicians have developed robotic surgical programs. Prospective trials are needed to define the short- and long-term benefits of the robotic Whipple procedure.

  11. Image fusion and navigation platforms for percutaneous image-guided interventions.

    PubMed

    Rajagopal, Manoj; Venkatesan, Aradhana M

    2016-04-01

    Image-guided interventional procedures, particularly image guided biopsy and ablation, serve an important role in the care of the oncology patient. The need for tumor genomic and proteomic profiling, early tumor response assessment and confirmation of early recurrence are common scenarios that may necessitate successful biopsies of targets, including those that are small, anatomically unfavorable or inconspicuous. As image-guided ablation is increasingly incorporated into interventional oncology practice, similar obstacles are posed for the ablation of technically challenging tumor targets. Navigation tools, including image fusion and device tracking, can enable abdominal interventionalists to more accurately target challenging biopsy and ablation targets. Image fusion technologies enable multimodality fusion and real-time co-displays of US, CT, MRI, and PET/CT data, with navigational technologies including electromagnetic tracking, robotic, cone beam CT, optical, and laser guidance of interventional devices. Image fusion and navigational platform technology is reviewed in this article, including the results of studies implementing their use for interventional procedures. Pre-clinical and clinical experiences to date suggest these technologies have the potential to reduce procedure risk, time, and radiation dose to both the patient and the operator, with a valuable role to play for complex image-guided interventions.

  12. Risk of adverse pregnancy and perinatal outcomes after high technology infertility treatment: a comprehensive systematic review.

    PubMed

    2016-11-04

    In the literature, there is growing evidence that subfertile patients who conceived after infertility treatments have an increased risk of pregnancy and perinatal complications and this is particularly true for patients who conceived through use of high technology infertility treatments. Moreover, high technology infertility treatments include many concomitant clinical and biological risk factors. This review aims to summarize in a systematic fashion the current evidence regarding the relative effect of the different procedures for high technology infertility treatments on the risk of adverse pregnancy and perinatal outcome. A literature search up to August 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar and an evidence-based hierarchy was used to determine which articles to include and analyze. Data on prepregnancy maternal factors, low technology interventions, specific procedures for male factor, ovarian tissue/ovary and uterus transplantation, and chromosomal abnormalities and malformations of the offspring were excluded. The available evidences were analyzed assessing the level and the quality of evidence according to the Oxford Centre for Evidence-Based Medicine guidelines and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively. Current review highlights that every single procedure of high technology infertility treatments can play a crucial role in increasing the risk of pregnancy and perinatal complications. Due to the suboptimal level and quality of the current evidence, further well-designed studies are needed.

    Purpose Interventional MRI has significant potential for image guidance of iliac angioplasty and related vascular procedures. A technology framework with in-room image display, control, communication and MRI-guided intervention techniques was designed and tested for its potential to provide safe, fast and efficient MRI-guided angioplasty of the iliac arteries. Methods A 1.5T MRI scanner was adapted for interactive imaging during endovascular procedures using new or modified interventional devices such as guidewires and catheters. A perfused vascular phantom was used for testing. Pre-, intra- and post-procedural visualization and measurement of vascular morphology and flow was implemented. A detailed analysis of X-Ray fluoroscopic angiography workflow was conducted and applied. Two interventional radiologists and one physician in training performed 39 procedures. All procedures were timed and analyzed. Results MRI-guided iliac angioplasty procedures were successfully performed with progressive adaptation of techniques and workflow. The workflow, setup and protocol enabled a reduction in table time for a dedicated MRI-guided procedure to 6 min 33 s with a mean procedure time of 9 min 2 s, comparable to the mean procedure time of 8 min 42 s for the standard X-Ray guided procedure. Conclusions MRI-guided iliac vascular interventions were found to be feasible and practical using this framework and optimized workflow. In particular the real-time flow analysis was found to be helpful for pre- and post-interventional assessments. Design optimization of the catheters and in vivo experiments are required before clinical evaluation. PMID:25102933

    2013-01-01

    Motion capture based on magneto-inertial sensors is a technology enabling data collection in unstructured environments, allowing "out of the lab" motion analysis. This technology is a good candidate for motion analysis of children thanks to the reduced weight and size as well as the use of wireless communication that has improved its wearability and reduced its obtrusivity. A key issue in the application of such technology for motion analysis is its calibration, i.e. a process that allows mapping orientation information from each sensor to a physiological reference frame. To date, even if there are several calibration procedures available for adults, no specific calibration procedures have been developed for children. This work addresses this specific issue presenting a calibration procedure for motion capture of thorax and upper limbs on healthy children. Reported results suggest comparable performance with similar studies on adults and emphasize some critical issues, opening the way to further improvements.

    1975-01-01

    The results of classifications and experiments performed for the Crop Identification Technology Assessment for Remote Sensing (CITARS) project are summarized. Fifteen data sets were classified using two analysis procedures. One procedure used class weights while the other assumed equal probabilities of occurrence for all classes. In addition, 20 data sets were classified using training statistics from another segment or date. The results of both the local and non-local classifications in terms of classification and proportion estimation are presented. Several additional experiments are described which were performed to provide additional understanding of the CITARS results. These experiments investigated alternative analysis procedures, training set selection and size, effects of multitemporal registration, the spectral discriminability of corn, soybeans, and other, and analysis of aircraft multispectral data.

    2008-01-01

    Objective To describe our experience with coblation technology for facial resurfacing Methods Retrospective chart review of all patients treated with coblation at our institution Results Twenty-four patients (22 female) underwent a total of 29 coblation procedures for aging face (n = 21) or acne scarring (n = 3). The perioral region was the most frequently treated aesthetic subunit (n = 14), followed by the lower eyelid (n = 7). Five patients underwent full-face coblation. Three patients underwent a second coblation procedure for aging face while a single patient with severe acne scarring underwent 3 procedures. Repeat coblation was delayed at least 5 months (mean, 9 months). Seventeen coblation procedures (59%) were performed concurrently with procedures including, but not limited to, injection treatment, rhinoplasty, blepharoplasty, or combined face/necklift; no adverse events occurred. Seven procedures, including a full-face coblation, were performed in the office under local anesthesia and oral sedation without any adverse events. Mean follow-up was 6 months (range, 1 week to 24 months). No complications were observed. All patients were satisfied with the results after their final coblation treatment. Conclusions Facial coblation is a safe and effective treatment modality for facial resurfacing. PMID:18769690

    2014-01-01

    Since its introduction by Illouz and others over 30 years ago, suction-assisted lipectomy/liposuction/lipoplasty has evolved tremendously and has developed into one of the most popular procedures in aesthetic plastic surgery. Liposuction is an effective procedure employed to treat localized adipose deposits in patients not suffering from generalized obesity. These accumulations of subcutaneous fat often occur in predictable distributions in both men and women. A cannula connected to a suction-generating source allows for small incisions to be strategically placed and large volumes of fat to be removed. This fat removal leads to improved harmonious balance of a patient’s physique and improved body contour. Various surgical techniques are available and have evolved as technology has improved. Current technology for liposuction includes suction-assisted lipectomy, ultrasound-assisted, power-assisted, laser-assisted, and radiofrequency-assisted. The choice of technology and technique often depends on patient characteristics and surgeon preference. The objective of this review is to provide a thorough assessment of current technologies available to plastic surgeons performing liposuction. PMID:25093000

    2015-01-01

    Leveraging advances in consumer electronics and wireless telecommunications, low-cost, portable optical imaging devices have the potential to improve screening and detection of disease at the point of care in primary health care settings in both low- and high-resource countries. Similarly, real-time optical imaging technologies can improve diagnosis and treatment at the point of procedure by circumventing the need for biopsy and analysis by expert pathologists, who are scarce in developing countries. Although many optical imaging technologies have been translated from bench to bedside, industry support is needed to commercialize and broadly disseminate these from the patient level to the population level to transform the standard of care. This review provides an overview of promising optical imaging technologies, the infrastructure needed to integrate them into widespread clinical use, and the challenges that must be addressed to harness the potential of these technologies to improve health care systems around the world.

    1988-01-01

    Many future space based vehicles and satellites will require on orbit refuelling procedures. Cryogenic fluid management technology is being developed to assess the requirements of such procedures as well as to aid in the design and development of these vehicles. Cryogenic fluid management technology for this application could be divided into two areas of study, one is concerned with fluid transfer process and the other with cryogenic liquid storage. This division is based upon the needed technology for the development of each area. In the first, the interaction of fluid dynamics with thermodynamics is essential, while in the second only thermodynamic analyses are sufficient to define the problem. The following specific process related to the liquid transfer area are discussed: tank chilldown and fill; tank pressurization; liquid positioning; and slosh dynamics and control. These specific issues are discussed in relation with the required technology for their development in the low gravity application area. In each process the relevant physics controlling the technology is identified and methods for resolving some of the basic questions are discussed.

    2006-10-01

    This paper, the second of 3 that discuss the reimbursement challenges facing new medical device technology in various issues of this journal, explains the key aspects of coverage that affect the adoption of medical devices. The process Medicare uses to make coverage determinations has become more timely and open over the past several years, but it still lacks the predictability that product innovators prefer. The continued uncertainty surrounding evidence requirements undermines the predictability needed for optimal product planning and innovation. Recent steps taken by the Centers for Medicare and Medicaid Services to provide coverage in return for evidence development should provide patients with access to promising new technologies and procedures while generating important evidence concerning their effectiveness.

    2002-05-01

    A decision to invest in and develop laser technology should only be made after a thorough investigation and comparison of the available types, vendors, available features, and purchasing options. A sound marketing program must then be used for introducing laser technology to the staff, clients, and colleagues. Without adhering to such a program, a practice will [figure: see text] not experience the necessary profitability following the purchase of a laser. Staff enthusiasm and support will dwindle, and ultimately the laser investment will be viewed unfavorably. When marketed properly, however, the investment in a surgical laser will provide outstanding profitability. The return on investment can be provided by using the support staff for client education, by offering laser technology for routine elective procedures and complex procedures, and by adhering strictly to a fee schedule. Add that to the truly remarkable results obtained using laser surgical techniques, a practice will be greatly enhanced.

    Near the end of FY 1994, DOE provided funding and guidance to INEL for two separate but closely related tasks involving high power energy storage technology. One task was intended to develop and refine application-specific test procedures appropriate to high power energy storage devices for potential use in hybrid vehicles, including batteries, ultracapacitors, flywheels, and similar devices. The second task was intended to characterize the high power capabilities of presently available battery technologies, as well as eventually to evaluate the potential high power capabilities of advanced battery technologies such as those being developed by the USABC. Since the evaluation ofmore » such technologies is necessarily dependent to some extent on the availability of appropriate test methods, these two tasks have been closely coordinated.

  17. Using tablet technology and instructional videos to enhance preclinical dental laboratory learning.

    PubMed

    Gadbury-Amyot, Cynthia C; Purk, John H; Williams, Brian Joseph; Van Ness, Christopher J

    2014-02-01

    The purpose of this pilot study was to examine if tablet technology with accompanying instructional videos enhanced the teaching and learning outcomes in a preclinical dental laboratory setting. Two procedures deemed most challenging in Operative Dentistry II were chosen for the development of instructional videos. A random sample of thirty students was chosen to participate in the pilot. Comparison of faculty evaluations of the procedures between the experimental (tablet) and control (no tablet) groups resulted in no significant differences; however, there was a trend toward fewer failures in the experimental group. Examination of the ability to accurately self-assess was compared by exploring correlations between faculty and student evaluations. While correlations were stronger in the experimental group, the control group had significant correlations for all three procedures, while the experimental group had significant correlations on only two of the procedures. Students strongly perceived that the tablets and videos helped them perform better and more accurately self-assess their work products. Students did not support requiring that they purchase/obtain a specific brand of technology. As a result of this pilot study, further development of ideal and non-ideal videos are in progress, and the school will be implementing a "Bring Your Own Device" policy with incoming students.

  18. Economic impact of corrosion and scaling problems in geothermal energy systems

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Shannon, D.W.

    Corrosion and scaling problems have a significant impact on geothermal plant economics. A power plant must amortize the capital investment over a 20-year period and achieve satisfactory operating efficiency to achieve financial success. Corrosion and scale incrustations have been encountered in all geothermal plants, and to various degrees, adversely affected plant life times and power output. Using published data this report analyzes known geothermal corrosion and scaling phenomena for significant cost impacts on plant design and operation. It has been necessary to speculate about causes and mechanisms in order to estimate impacts on conceptual geothermal plants. Silica is highly solublemore » in hot geothermal water and solubility decreases as water is cooled in a geothermal power plant. Calculations indicate as much as 30,000 tons/year could pass through a 100 MWe water cycle plant. The major cost impact will be on the reinjection well system where costs of 1 to 10 mills/kwhr of power produced could accrue to waste handling alone. On the other hand, steam cycle geothermal plants have a definite advantage in that significant silica problems will probably only occur in hot dry rock concepts, where steam above 250 C is produced. Calculation methods are given for estimating the required size and cost impact of a silica filtration plant and for sizing scrubbers. The choice of materials is significantly affected by the pH of the geothermal water, temperature, chloride, and H{sub s} contents. Plant concepts which attempt to handle acid waters above 180 C will be forced to use expensive corrosion resistant alloys or develop specialized materials. On the other hand, handling steam up to 500 C, and pH 9 water up to 180 C appears feasible using nominal cost steels, typical of today's geothermal plants. A number of factors affecting plant or component availability have been identified. The most significant is a corrosion fatigue problem in geothermal turbines at the Geyser's geothermal plant which is presently reducing plant output by about 10%. This is equivalent to over $3 million per year in increased oil consumption to replace the power. In the course of assessing the cost implications of corrosion and scaling problems, a number of areas of technological uncertainty were identified which should be considered in R and D planning in support of geothermal energy. Materials development with both laboratory and field testing will be necessary. The economic analysis on which this report is based was done in support of an AEC Division of Applied Technology program to assess the factors affecting geothermal plant economics. The results of this report are to be used to develop computer models of overall plant economics, of which corrosion and scaling problems are only a part. The translation of the economic analysis to the report which appears here, was done on AEC Special Studies Funds.« less

  19. Experience with virtual reality-based technology in teaching restorative dental procedures.

    PubMed

    Buchanan, Judith A

    2004-12-01

    This article reports on extensive experience with advanced simulation at the University of Pennsylvania, School of Dental Medicine (UPSDM). Virtual reality-based technology (VRBT) or advanced simulation is currently available for the instruction of dental students in preclinical restorative procedures. UPSDM was one of the first schools in the world to have extensive experience with VRBT technology using an advanced simulation unit (DentSim) from DenX, Ltd. UPSDM's experience consists of several years of research using control and experimental groups, employing students to participate in an investigative project, and using the units for remediation and a supplement to the preclinical laboratory. Currently, all first-year students (Class of 2007 and Class of 2008) are receiving most of their preparative operative training on the VRBT units. UPSDM started with one (beta) version unit in 1998, which was later updated and expanded first to four units and recently to fifteen units. This communication is presenting the studies that were of fundamental importance in making the decision to acquire fifteen units in 2003. The areas of main interest to the SDM concerning this technology were its use in teaching, refreshing, and remediating students in restorative procedures and its effectiveness as a teaching methodology in relation to time, efficiency, and faculty. Several studies with varying parameters were performed at various time points. The limited statistical analysis conducted was not conclusive for all measures, and in some cases the data only suggest areas of possible significance. This is due to the low number of students who could access the limited number of available units and the change of protocols in response to student and faculty input. Overall, the results do suggest, however, that students learn faster, arrive at the same level of performance, accomplish more practice procedures per hour, and request more evaluations per procedure or per hour than in our traditional laboratories. Students' attitudes, as measured by surveys, group interviews, and private interviews, are mixed. Our overall evaluation of our experience with this technology has been positive and led to the purchase of additional units, its full incorporation into our curriculum, and curriculum revision to maximize its potential. Our conclusion is that this technology offers significant potential in the field of dental education and that further use and investigation are both desired and justified.

    Summary Introduction. The objective of this paper is the comparison between two different technologies used for the removal of a uterine myoma, a frequent benign tumor: the standard technology currently used, laparoscopy, and an innovative one, colpoceliotomy. It was considered relevant to evaluate the real and the potential effects of the two technologies implementation and, in addition, the consequences that the introduction or exclusion of the innovative technology would have for both the National Health System (NHS) and the entire community. Methods. The comparison between these two different technologies, the standard and the innovative one, was conducted using a Health Technology Assessment (HTA). In particular, in order to analyse their differences, a multi-dimensional approach was considered: effectiveness, costs and budget impact analysis data were collected, applying different instruments, such as the Activity Based Costing methodology (ABC), the Cost-Effectiveness Analysis (CEA) and the Budget Impact Analysis (BIA). Organisational, equity and social impact were also evaluated. Results. The results showed that the introduction of colpoceliotomy would provide significant economic savings to the Regional and National Health Service; in particular, a saving of € 453.27 for each surgical procedure. Discussion. The introduction of the innovative technology, colpoceliotomy, could be considered a valuable tool; one offering many advantages related to less invasiveness and a shorter surgical procedure than the standard technology currently used (laparoscopy).

  4. Improving Performance During Image-Guided Procedures

    PubMed Central

    Duncan, James R.; Tabriz, David

    2015-01-01

    Objective Image-guided procedures have become a mainstay of modern health care. This article reviews how human operators process imaging data and use it to plan procedures and make intraprocedural decisions. Methods A series of models from human factors research, communication theory, and organizational learning were applied to the human-machine interface that occupies the center stage during image-guided procedures. Results Together, these models suggest several opportunities for improving performance as follows: 1. Performance will depend not only on the operator’s skill but also on the knowledge embedded in the imaging technology, available tools, and existing protocols. 2. Voluntary movements consist of planning and execution phases. Performance subscores should be developed that assess quality and efficiency during each phase. For procedures involving ionizing radiation (fluoroscopy and computed tomography), radiation metrics can be used to assess performance. 3. At a basic level, these procedures consist of advancing a tool to a specific location within a patient and using the tool. Paradigms from mapping and navigation should be applied to image-guided procedures. 4. Recording the content of the imaging system allows one to reconstruct the stimulus/response cycles that occur during image-guided procedures. Conclusions When compared with traditional “open” procedures, the technology used during image-guided procedures places an imaging system and long thin tools between the operator and the patient. Taking a step back and reexamining how information flows through an imaging system and how actions are conveyed through human-machine interfaces suggest that much can be learned from studying system failures. In the same way that flight data recorders revolutionized accident investigations in aviation, much could be learned from recording video data during image-guided procedures. PMID:24921628

  5. Measuring discharge with acoustic Doppler current profilers from a moving boat

    Mueller, David S.; Wagner, Chad R.; Rehmel, Michael S.; Oberg, Kevin A.; Rainville, Francois

    2013-01-01

    The use of acoustic Doppler current profilers (ADCPs) from a moving boat is now a commonly used method for measuring streamflow. The technology and methods for making ADCP-based discharge measurements are different from the technology and methods used to make traditional discharge measurements with mechanical meters. Although the ADCP is a valuable tool for measuring streamflow, it is only accurate when used with appropriate techniques. This report presents guidance on the use of ADCPs for measuring streamflow; this guidance is based on the experience of U.S. Geological Survey employees and published reports, papers, and memorandums of the U.S. Geological Survey. The guidance is presented in a logical progression, from predeployment planning, to field data collection, and finally to post processing of the collected data. Acoustic Doppler technology and the instruments currently (2013) available also are discussed to highlight the advantages and limitations of the technology. More in-depth, technical explanations of how an ADCP measures streamflow and what to do when measuring in moving-bed conditions are presented in the appendixes. ADCP users need to know the proper procedures for measuring discharge from a moving boat and why those procedures are required, so that when the user encounters unusual field conditions, the procedures can be adapted without sacrificing the accuracy of the streamflow-measurement data.

    An explosion of knowledge and technology is revolutionizing medicine and patient care. Novel testing must be brought to the clinic with safety and accuracy, but also in a timely and cost-effective manner, so that patients can benefit and laboratories can offer testing consistent with current guidelines. Under the oversight provided by the Clinical Laboratory Improvement Amendments, laboratories have been able to develop and optimize laboratory procedures for use in-house. Quality improvement programs, interlaboratory comparisons, and the ability of laboratories to adjust assays as needed to improve results, utilize new sample types, or incorporate new mutations, information, or technologies are positive aspects of Clinical Laboratory Improvement Amendments oversight of laboratory-developed procedures. Laboratories have a long history of successful service to patients operating under Clinical Laboratory Improvement Amendments. A series of detailed clinical examples illustrating the quality and positive impact of laboratory-developed procedures on patient care is provided. These examples also demonstrate how Clinical Laboratory Improvement Amendments oversight ensures accurate, reliable, and reproducible testing in clinical laboratories. PMID:28815200

    2013-02-01

    This study assessed technology-aided programs for helping two post-coma persons, who had emerged from a minimally conscious state and were affected by multiple disabilities, to (a) engage with leisure stimuli and request caregiver's procedures, (b) send out and listen to text messages for communication with distant partners, and (c) combine leisure engagement and procedure requests with text messaging within the same sessions. The program for leisure engagement and procedure requests relied on the use of a portable computer with commercial software, and a microswitch for the participants' response. The program for text messaging communication involved the use of a portable computer, a GSM modem, a microswitch for the participants' response, and specifically developed software. Results indicated that the participants were successful at each of the three stages of the study, thus providing relevant evidence concerning performance achievements only minimally documented. The implications of the findings in terms of technology and practical opportunities for post-coma persons with multiple disabilities are discussed. Copyright © 2012 Elsevier Ltd.

  1. Flat panel display test and evaluation: procedures, standards, and facilities

    NASA Astrophysics Data System (ADS)

    Jackson, Timothy W.; Daniels, Reginald; Hopper, Darrel G.

    1997-07-01

    This paper addresses flat panel display test and evaluation via a discussion of procedures, standards and facilities. Procedures need to be carefully developed and documented to ensure that test accomplished in separate laboratories produce comparable results. The tests themselves must not be a source of inconsistency in test results when such comparisons are made in the course of procurements or new technology prototype evaluations. Standards are necessary to expedite the transition of the new display technologies into applications and to lower the costs of custom parts applied across disparate applications. The flat panel display industry is in the course of ascertaining and formulating such standards as they are of value to designers, manufacturers, marketers and users of civil and military products and equipment. Additionally, in order to inform the DoD and industry, the test and evaluation facilities of the Air Force Research Laboratory Displays Branch are described. These facilities are available to support procurements involving flat panel displays and to examine new technology prototypes. Finally, other government display testing facilities within the Navy and the Army are described.

  2. Robotics in Gynecology: Why is this Technology Worth Pursuing?

    Robotic laparoscopy in gynecology, which started in 2005 when the Da Vinci Surgical System (Intuitive Surgical Inc) was approved by the US Food and Drug Administration for use in gynecologic procedures, represents today a modern, safe, and precise approach to pathology in this field. Since then, a great deal of experience has accumulated, and it has been shown that there is almost no gynecological surgery that cannot be approached with this technology, namely hysterectomy, myomectomy, sacrocolpopexia, and surgery for the treatment of endometriosis. Albeit no advantages have been observed over conventional laparoscopy and some open surgical procedures, robotics do seem to be advantageous in highly complicated procedures when extensive dissection and proper anatomy reestablishment is required, as in the case of oncologic surgery. There is no doubt that implementation of better logistics in finance, training, design, and application will exert a positive effect upon robotics expansion in gynecological medicine. Contrary to expectations, we estimate that a special impact is to be seen in emerging countries where novel technologies have resulted in benefits in the organization of health care systems.

  3. A Simulation Study of Instrument Meteorological Condition Approaches to Dual Parallel Runways Spaced 3400 and 2500 Feet Apart Using Flight-Deck-Centered Technology

    NASA Technical Reports Server (NTRS)

    Waller, Marvin C.; Scanlon, Charles H.

    1999-01-01

    A number of our nations airports depend on closely spaced parallel runway operations to handle their normal traffic throughput when weather conditions are favorable. For safety these operations are curtailed in Instrument Meteorological Conditions (IMC) when the ceiling or visibility deteriorates and operations in many cases are limited to the equivalent of a single runway. Where parallel runway spacing is less than 2500 feet, capacity loss in IMC is on the order of 50 percent for these runways. Clearly, these capacity losses result in landing delays, inconveniences to the public, increased operational cost to the airlines, and general interruption of commerce. This document presents a description and the results of a fixed-base simulation study to evaluate an initial concept that includes a set of procedures for conducting safe flight in closely spaced parallel runway operations in IMC. Consideration of flight-deck information technology and displays to support the procedures is also included in the discussions. The procedures and supporting technology rely heavily on airborne capabilities operating in conjunction with the air traffic control system.

  4. Comparison of mapping algorithms used in high-throughput sequencing: application to Ion Torrent data

    PubMed Central

    2014-01-01

    Background The rapid evolution in high-throughput sequencing (HTS) technologies has opened up new perspectives in several research fields and led to the production of large volumes of sequence data. A fundamental step in HTS data analysis is the mapping of reads onto reference sequences. Choosing a suitable mapper for a given technology and a given application is a subtle task because of the difficulty of evaluating mapping algorithms. Results In this paper, we present a benchmark procedure to compare mapping algorithms used in HTS using both real and simulated datasets and considering four evaluation criteria: computational resource and time requirements, robustness of mapping, ability to report positions for reads in repetitive regions, and ability to retrieve true genetic variation positions. To measure robustness, we introduced a new definition for a correctly mapped read taking into account not only the expected start position of the read but also the end position and the number of indels and substitutions. We developed CuReSim, a new read simulator, that is able to generate customized benchmark data for any kind of HTS technology by adjusting parameters to the error types. CuReSim and CuReSimEval, a tool to evaluate the mapping quality of the CuReSim simulated reads, are freely available. We applied our benchmark procedure to evaluate 14 mappers in the context of whole genome sequencing of small genomes with Ion Torrent data for which such a comparison has not yet been established. Conclusions A benchmark procedure to compare HTS data mappers is introduced with a new definition for the mapping correctness as well as tools to generate simulated reads and evaluate mapping quality. The application of this procedure to Ion Torrent data from the whole genome sequencing of small genomes has allowed us to validate our benchmark procedure and demonstrate that it is helpful for selecting a mapper based on the intended application, questions to be addressed, and the technology used. This benchmark procedure can be used to evaluate existing or in-development mappers as well as to optimize parameters of a chosen mapper for any application and any sequencing platform.

    1997-01-01

    The use of various methodologies to predict the impact of future Air Traffic Management (ATM) concepts and technologies is explored. The emphasis has been on the importance of modeling coordination and cooperation among multiple agents within this system, and on understanding how the interactions among these agents will be influenced as new roles, responsibilities, procedures and technologies are introduced. To accomplish this, we have been collecting data on performance under the current air traffic management system, identifying critical problem areas and looking for examples suggestive of general approaches for solving such problems. Using the results of these field studies, we have developed a set of concrete scenarios centered around future designs, and have studied performance in these scenarios with a set of 40 controllers, dispatchers, pilots and traffic managers.

  15. Surgical robotics in otolaryngology: expanding the technology envelope.

    PubMed

    Gourin, Christine G; Terris, David J

    2004-06-01

    Surgical robotics arose as an extension of virtual reality and robotic technology developed by the United States Department of Defense. Current surgical robotic systems have been used to perform a variety of minimally invasive surgical procedures. The Food and Drug Administration recently granted approval for the clinical use of two surgical robotic systems. Laboratory and clinical experience suggests that the use of surgical robotics is associated with some distinct advantages and disadvantages when compared with conventional open procedures. Robotic surgery has recently been described in the head and neck, and as a result the otolaryngologist should have a basic understanding of the potential applications of surgical robotics in head and neck surgery. Surgical robotic technology is evolving but appears to have a distinct place in the surgical armamentarium.

    Joglekar, Prafulla; Zapata, Edgar

    2001-01-01

    As part of Kennedy Space Center's (KSC's) challenge to open the space frontier, new spaceport technologies must be developed, matured and successfully transitioned to operational systems. R&D investment decisions can be considered from multiple perspectives. Near mid and far term technology horizons must be understood. Because a multitude of technology investment opportunities are available, we must identify choices that promise the greatest likelihood of significant lifecycle At the same time, the costs and risks of any choice must be well understood and balanced against its potential returns The problem is not one of simply rank- ordering projects in terms of their desirability. KSC wants to determine a portfolio of projects that simultaneously satisfies multiple goals, such as getting the biggest bang for the buck, supporting projects that may be too risky for private funding, staying within annual budget cycles without foregoing the requirements of a long term technology vision, and ensuring the development of a diversity of technologies that, support the variety of operational functions involved in space transportation. This work aims to assist in the development of in methods and techniques that support strategic technology investment decisions and ease the process of determining an optimal portfolio of spaceport R&D investments. Available literature on risks and returns to R&D is reviewed and most useful pieces are brought to the attention of the Spaceport Technology Development Office (STDO). KSC's current project management procedures are reviewed. It is found that the "one size fits all" nature of KSC's existing procedures and project selection criteria is not conducive to prudent decision-making. Directions for improving KSC's - procedures and criteria are outlined. With help of a contractor, STDO is currently developing a tool, named Change Management Analysis Tool (CMAT)/ Portfolio Analysis Tool (PAT), to assist KSC's R&D portfolio determination. A critical review of CMAT/PAT is undertaken. Directions for the improvement of this tool are provided. STDO and KSC intend to follow up on many, if not all, of the recommendations provided.

  18. Virtual simulation as a learning method in interventional radiology.

    PubMed

    Avramov, Predrag; Avramov, Milena; Juković, Mirela; Kadić, Vuk; Till, Viktor

    2013-01-01

    Radiology is the fastest growing discipline of medicine thanks to the implementation of new technologies and very rapid development of imaging diagnostic procedures in the last few decades. On the other hand, the development of imaging diagnostic procedures has put aside the traditional gaining of experience by working on real patients, and the need for other alternatives of learning interventional radiology procedures has emerged. A new method of virtual approach was added as an excellent alternative to the currently known methods of training on physical models and animals. Virtual reality represents a computer-generated reconstruction of anatomical environment with tactile interactions and it enables operators not only to learn on their own mistakes without compromising the patient's safety, but also to enhance their knowledge and experience. It is true that studies published so far on the validity of endovascular simulators have shown certain improvement of operator's technical skills and reduction in time needed for the procedure, but on the other hand, it is still a question whether these skills are transferable to the real patients in the angio room. With further improvement of technology, shortcomings of virtual approach to interventional procedures learning will be less significant and this procedure is likely to become the only method of learning in the near future.

  19. POWER-ENHANCED MULTIPLE DECISION FUNCTIONS CONTROLLING FAMILY-WISE ERROR AND FALSE DISCOVERY RATES.

    PubMed

    Peña, Edsel A; Habiger, Joshua D; Wu, Wensong

    2011-02-01

    Improved procedures, in terms of smaller missed discovery rates (MDR), for performing multiple hypotheses testing with weak and strong control of the family-wise error rate (FWER) or the false discovery rate (FDR) are developed and studied. The improvement over existing procedures such as the Šidák procedure for FWER control and the Benjamini-Hochberg (BH) procedure for FDR control is achieved by exploiting possible differences in the powers of the individual tests. Results signal the need to take into account the powers of the individual tests and to have multiple hypotheses decision functions which are not limited to simply using the individual p -values, as is the case, for example, with the Šidák, Bonferroni, or BH procedures. They also enhance understanding of the role of the powers of individual tests, or more precisely the receiver operating characteristic (ROC) functions of decision processes, in the search for better multiple hypotheses testing procedures. A decision-theoretic framework is utilized, and through auxiliary randomizers the procedures could be used with discrete or mixed-type data or with rank-based nonparametric tests. This is in contrast to existing p -value based procedures whose theoretical validity is contingent on each of these p -value statistics being stochastically equal to or greater than a standard uniform variable under the null hypothesis. Proposed procedures are relevant in the analysis of high-dimensional "large M , small n " data sets arising in the natural, physical, medical, economic and social sciences, whose generation and creation is accelerated by advances in high-throughput technology, notably, but not limited to, microarray technology.

    2017-06-01

    Within the last 10 years there have been significant advances in minimal-access surgery. Although no emerging technology has demonstrated improved outcomes or fewer complications than standard laparoscopy, the introduction of the robotic surgical platform has significantly lowered abdominal hysterectomy rates. While operative time and cost were higher in robotic-assisted procedures when the technology was first introduced, newer studies demonstrate equivalent or improved robotic surgical efficiency with increased experience. Single-port hysterectomy has not improved postoperative pain or subjective cosmetic results. Emerging platforms with flexible, articulating instruments may increase the uptake of single-port procedures including natural orifice transluminal endoscopic cases.

    This software implements the first base caller for nanopore data that calls bases directly from raw data. The basecRAWller algorithm has two major advantages over current nanopore base calling software: (1) streaming base calling and (2) base calling from information rich raw signal. The ability to perform truly streaming base calling as signal is received from the sequencer can be very powerful as this is one of the major advantages of this technology as compared to other sequencing technologies. As such enabling as much streaming potential as possible will be incredibly important as this technology continues to become more widelymore » applied in biosciences. All other base callers currently employ the Viterbi algorithm which requires the whole sequence to employ the complete base calling procedure and thus precludes a natural streaming base calling procedure. The other major advantage of the basecRAWller algorithm is the prediction of bases from raw signal which contains much richer information than the segmented chunks that current algorithms employ. This leads to the potential for much more accurate base calls which would make this technology much more valuable to all of the growing user base for this technology.« less

    The purpose of this paper is to describe and discuss how we designed and developed a 12-step technology training protocol. The protocol is meant to improve meaningful learning in technology education so that nursing students are able to meet the informatics requirements of Quality and Safety Education in Nursing competencies. When designing and developing the training protocol, we used a simplified experiential learning model that addressed the core features of meaningful learning: to connect new knowledge with students' prior knowledge and real-world workflow. Before training, we identified students' prior knowledge and workflow tasks. During training, students learned by doing, reflected on their prior computer skills and workflow, designed individualized procedures for integration into their workflow, and practiced the self-designed procedures in real-world settings. The trainer was a facilitator who provided a meaningful learning environment, asked the right questions to guide reflective conversation, and offered scaffoldings at critical moments. This training protocol could significantly improve nurses' competencies in using technologies and increase their desire to adopt new technologies. © 2017 Wiley Periodicals, Inc.

    From classical surgery to Robotic Assisted Surgery, there is a long way allowed by Minimal Invasive Surgery' improvements. The last three decades have witnessed a prodigious development of minimally invasive surgery (MIS) and especially in the field of laparoscopic pediatric surgery but there are several limitations in the use of conventional laparoscopic surgery and Robotic Assisted Surgery was developed to relieve these drawbacks. This new technology enables today the performance of a wide variety of procedures in children with a minimally invasive approach. As for all new technologies, an objective evaluation is essential with the need to respond to several questions: Is the technology feasible? Is the technology safe? Is the technology efficient? Does it bring about benefits compared with current technology? What are the procedures derived from most benefits of robotic assistance? How to assume the transition from open surgery to Minimal Invasive access for RAS? In the first part of this article, the authors give details about technical concerns and then describe the implementation process with its organization, pitfalls, successes, and issues from human resources and financial standpoints. The learning curve is then described and a special focus on small children weighing less than 15 Kg is developed. Finally, the concept of evaluation of this emerging technology is evocated and financial concerns are developed.

  19. Corneal refractive surgery: Is intracorneal the way to go and what are the needs for technology?

    NASA Astrophysics Data System (ADS)

    Hjortdal, Jesper; Ivarsen, Anders

    2014-02-01

    Corneal refractive surgery aims to reduce or eliminate refractive errors of the eye by changing the refractive power of the cornea. For the last 20 years controlled excimer laser ablation of corneal tissue, either directly from the corneal stromal surface or from the corneal interior after creation of a superficial corneal flap has become widely used to correct myopia, hyperopia, and astigmatism. Recently, an intrastromal refractive procedure whereby a tissue lenticule is cut free in the corneal stroma by a femtosecond laser and removed through a small peripheral incision has been introduced. This procedure avoids creation of a corneal flap and the potential associated risks while avoiding the slow visual recovery of surface ablation procedures. Precise intrastromal femtosecond laser cutting of the fine lenticule requires very controlled laser energy delivery in order to avoid lenticule irregularities, which would compromise the refractive result and visual acuity. This newly introduced all-femtosecond based flap-free intracorneal refractive procedure has been documented to be a predictable, efficient, and safe procedure for correction of myopia and astigmatism. Technological developments related to further improved cutting quality, hyperopic and individualized treatments are desirable.

    There has been significant growth in the volume and complexity of percutaneous structural heart procedures in the past decade. Increasing procedural complexity and accompanying reliance on multimodality imaging have fueled the development of fusion imaging to facilitate procedural guidance. The first clinically available system capable of echocardiographic and fluoroscopic fusion for real-time guidance of structural heart procedures was approved by the US Food and Drug Administration in 2012. Echocardiographic-fluoroscopic fusion imaging combines the precise catheter and device visualization of fluoroscopy with the soft tissue anatomy and color flow Doppler information afforded by echocardiography in a single image. This allows the interventionalist to perform precise catheter manipulations under fluoroscopy guidance while visualizing critical tissue anatomy provided by echocardiography. However, there are few data available addressing this technology's strengths and limitations in routine clinical practice. The authors provide a critical review of currently available echocardiographic-fluoroscopic fusion imaging for guidance of structural heart interventions to highlight its strengths, limitations, and potential clinical applications and to guide further research into value of this emerging technology.

    Most studies on the costs of assisted reproductive technologies (ART) identify the total cost of the procedure with the direct cost, without considering important items such as overhead or intermediate costs. The objective of this study was to determine the cost per ART procedure in a public hospital in 2003 and to compare the results with those in the same hospital in 1998. Data from the Human Reproduction Unit of the Virgen de las Nieves University Hospital in Granada (Spain) from 1998 and 2003 were analyzed. Since the total costs of the unit were known, the cost of the distinct ART procedures performed in the hospital was calculated by means of a methodology for cost distribution. Between 1998 and 2003, the activity and costs of the Human Reproduction Unit analyzed evolved differently. Analysis of activity showed that some techniques, such as intracytoplasmic sperm injection, were consolidated while others, such as stimulation without assisted reproduction or intracervical insemination were abandoned. In all procedures, unit costs per cycle and per delivery decreased in the period analyzed. Important changes took place in the structure of costs of ART in the Human Reproduction Unit of the Virgen de las Nieves University Hospital between 1998 and 2003. Some techniques were discontinued, while others gained importance. Technological advances and structural innovations, together with a "learning effect," modified the structure of ART-related costs.

  2. Toward a procedure for integrating moral issues in health technology assessment.

    PubMed

    Hofmann, Bjørn

    2005-01-01

    Although ethics has been on the agenda in health technology assessment (HTA) since its inception, the integration of moral issues is still not standard and is performed in a vast variety of ways. Therefore, there is a need for a procedure for integrating moral issues in HTA. Literature review of existing approaches together with application of various theories in moral philosophy and axiology. The article develops a set of questions that addresses a wide range of moral issues related to the assessment and implementation of health technology. The issues include general moral issues and moral issues related to stakeholders, methodology, characteristics of technology, and to the HTA process itself. The questions form a kind of checklist for use in HTAs. The presented approach for integrating moral issues in HTA has a broad theoretical foundation and has shown to be useful in practice. Integrating ethical issues in HTAs can be of great importance with respect to the dissemination of HTA results and in efficient health policy making.

  3. The effect of cutting conditions on power inputs when machining

    Any technological process involving modification of material properties or product form necessitates consumption of a certain power amount. When developing new technologies one should take into account the benefits of their implementation vs. arising power inputs. It is revealed that procedures of edge cutting machining are the most energy-efficient amongst the present day forming procedures such as physical and technical methods including electrochemical, electroerosion, ultrasound, and laser processing, rapid prototyping technologies etc, such as physical and technical methods including electrochemical, electroerosion, ultrasound, and laser processing, rapid prototyping technologies etc. An expanded formula for calculation of power inputs is deduced, which takes into consideration the mode of cutting together with the tip radius, the form of the replaceable multifaceted insert and its wear. Having taken as an example cutting of graphite iron by the assembled cutting tools with replaceable multifaceted inserts the authors point at better power efficiency of high feeding cutting in comparison with high-speed cutting.

    This study examined polarization of perceptions of Procedural Justice. Two polarization mechanisms are examined, Persuasive Arguments and Social Comparisons. Participants were students enrolled in a first-year introductory business class. There were 216 participants in the Persuasive Arguments study, 429 in the Social Comparisons study. The average age of all participants was 22.3 yr. (SD = 2.1); 56% were women. Fields of study represented were business, engineering, information technology, and sports. Analysis showed under conditions of low Procedural Justice, polarization effects were only found with the Persuasive Arguments mechanism. Under conditions of high Procedural Justice, polarization effects were only found with Social Comparisons. Implications for group polarization and Procedural Justice theories are considered.

  5. Integrating health technology assessment requirements in the clinical development of medicines: the experience from NICE scientific advice.

    PubMed

    2017-03-01

    The primary objective of the study was to analyse the proposed clinical development and economic evaluation plans for investigational medicinal products for which pharmaceutical companies have sought health technology assessment (HTA) scientific advice (SA). We have selected and analysed all the scientific advice procedures undertaken by National Institute for Health and Care Excellence (NICE) SA between 1 January 2009 and 3 December 2015 for investigational medicinal products. We have mapped the questions asked by the companies and the areas of advice highlighted in the advice reports to the sections of the NICE methods guide to the technology appraisals (2013). An overwhelming proportion of SA procedures have addressed questions related to the clinical development and specifically the main pivotal efficacy studies. Approximately a quarter of the questions relate to the approaches to economic evaluation. Questions raised in European Medicines Agency-HTA procedures generally focus on clinical efficacy issues whereas cost-effectiveness ones tend to dominate in NICE-only procedures. Our analysis shows that the issues mostly discussed in the HTA SA are the choice of comparator, the generalisability of the clinical trial evidence to the NHS practice and the impact of the clinical trial outcomes on quality of life and survival. Less disagreement with the developers' plans was seen in the choice of clinical endpoints, population definition, position of the technology in the treatment pathway and study design. Scientific advice is designed to improve the quality of evidence and approaches to evidence generation for future regulatory approval and HTA evaluation. Our experience to date suggests that payer requirements are inconsistently integrated in the clinical development programmes. More efforts should be dedicated to demonstrating the clinical value of new medicinal products to patients and key decision-makers.

  6. Economic appraisal of the angioplasty procedures performed in 2004 in a high-volume diagnostic and interventional cardiology unit.

    Growing interest in the use of drug-eluting stents (DESs) in coronary angioplasty has prompted the Healthcare Agency of the Emilia Romagna Region to draw up recommendations for their appropriate clinical use in high-risk patients. Since the adoption of any new technology necessitates economic appraisal, we analysed the resource consumption of the various types of angioplasty procedures and the impact on the budget of a cardiology department. A retrospective economic appraisal was carried out on the coronary angioplasty procedures performed in 2004 in the Department of Interventional Cardiology of Reggio Emilia. On the basis of the principles of activity-based costing, detailed hospital costs were estimated for each procedure and compared with the relevant diagnosis-related group (DRG) reimbursement. In 2004, the Reggio Emilia hospital performed 806 angioplasty procedures for a total expenditure of euro 5,176,268. These were 93 plain old balloon angioplasty procedures (euro 487,329), 401 procedures with bare-metal stents (euro 2,380,071), 249 procedures with DESs (euro 1,827,386) and 63 mixed procedures (euro 481,480). Reimbursements amounted to euro 5,816,748 (11% from plain old balloon angioplasty, 50% from bare-metal stent, 31% from DES and 8% from mixed procedures) with a positive margin of about euro 680,480 between costs incurred and reimbursements obtained, even if the reimbursement for DES and mixed procedures was not covering all the incurred costs. Analysis of the case-mix of procedures revealed that an overall positive margin between costs and DRG reimbursements was achieved. It therefore emerges that adherence to the indications of the Healthcare Agency of the Emilia Romagna Region for the appropriate clinical use of DESs is economically sustainable from the hospital enterprise point of view, although the DRG reimbursements are not able to differentiate among resource consumptions owing to the adoption of innovative technologies.

  7. Sedimentology of the Paestum travertines, Salerno, Southern Italy

    NASA Astrophysics Data System (ADS)

    Anzalone, E.; Ferreri, V.; D'Argenio, B.

    2009-04-01

    The Paestum travertines, outcrop in the southern part of the Sele plain (Campania, southern Italy)and span in age from the late Pleistocene to the Recent. We have considered both the travertines resting under the ancient town of Paestum (founded by Sybaris Greeks in the VII century b.C.) and in its vicinities, as well as the travertine incrustations that post-date the VII century a.C. and partly cover the archaeological area. The textures and sedimentary features of the above rocks allow the environmental dynamics of the ancient as well as of the recent travertine deposits to be interpreted. The age of the ancient travertines ranges from 30-40 ka to 70-75 ka, even though more recent times of deposition cannot be excluded. They are genetically related to the waters springing from the south- western margin of the Mesozoic-Tertiary carbonates of Monte Soprano and Monte Sottano. These waters flow also through the travertines and their neighbouring deposits, feeding other springs along the coast. The travertines, both in situ and forming the building blocks of the town walls, have been classified using the textural nomenclature of the primary incrustations. On this basis, different lithofacies have been recognized and grouped into 3 main lithofacies associations: 1) Microhermal and Stromatolitic Travertines associated with Grain Supported Phytoclastic Travertines (gentle to steep slope environments); this lithofacies association is largely represented in the foundation travertines as well as in the blocks used to build the walls and the monuments of the ancient town; 2) Phytohermal and Microhermal Travertines (rapid and waterfall environments); this lithofacies association is well exposed in the foundation travertines of Porta Marina (western side of the town) and in some wall blocks (e.g. nearby Porta Sirena, eastern side of the town); 3) Phytoclastic and Phytohermal Travertines (swamp and marsh environments); this lithofacies association is common in the blocks forming the town wall between Porta Sirena and Porta Giustizia (southern-eastern side of Paestum) and in the civil and sacred architecture. The time-space relationships among the above lithofacies associations clearly emerge in the Porta Marina area both in the Greek walls of the ancient town (slope and swamp facies) and in the outcropping travertine substrate (slope and waterfall deposits). Based on the above sedimentological results, it may be inferred that, like other ambient temperature travertine systems studied in southern Italy, the Paestum travertine growth developed over a gentle slope surface (in our case dipping to the west), laterally evolving into rapid and waterfall deposits. At the same time, the aggradational growth of the travertine system resulted in a flattened summit area with widespread swamp and marsh environments. The ruins of Paestum, including the lower parts of sacred and civil buildings as well as town roads and walls, are even today largely covered by recent semi-coherent travertines (tufa), originating from waters that encrusted and then "fossilized" a large part of the town. Inside the town walls, these materials were pedogenized and nowadays are largely cultivated around and within the archeological area. A portion of these deposits was removed during the excavations of the beginning of last century, but traces of them may still be observed in different parts of the ancient town. Like the foundation travertines, the recent deposits are mainly made up of calcareous encrustations. Gastropods, ostracods and other organisms typical of terrestrial humid environments may be found in the phytoclastic textures. Usually, they are weakly cemented and at places incorporate different materials, including brick, wood and coal fragments. These sediments patchy cover the town within the wall perimeter, for a few decimetres in the sacred areas, but reaching over 4 meters downhill and outside the walls: a process of "fossilization" that appears to have been particularly effective at Porta Marina, on the sea side of Paestum, where the door structures were almost completely buried by fan shaped calcareous deposits, precipitating from waters flowing from inside the town.

    2013-01-01

    Recent technological advances allow ventilation holes in (or adjacent to) cigarette filters to be produced using lasers instead of using the mechanical procedures of earlier techniques. Analytical chemistry can be used to compare the composition of mainstream smoke from experimental cigarettes having filters with mechanically produced ventilation holes to that of cigarettes with ventilation holes that were produced using laser technology. Established procedures were used to analyze the smoke composition of 38 constituents of mainstream smoke generated using standard conditions. There were no differences between the smoke composition of cigarettes with filter ventilation holes that were produced mechanically or through use of laser technology. The two methods for producing ventilation holes in cigarette filters are equivalent in terms of resulting mainstream smoke chemistry, at two quite different filter ventilation percentages.

    The 1992 Integrated Modular Engine (IME) design concept, proposed to the Air Force Space Systems Division as a candidate for a National Launch System (NLS) upper stage, emphasized a detailed Quality Functional Deployment (QFD) procedure which set the basis for its final selection. With a list of engine requirements defined and prioritized by the customer, a QFD procedure was implemented where the characteristics of a number of engine and component configurations were assessed for degree of requirement satisfaction. The QFD process emphasized operability, cost, reliability and performance, with relative importance specified by the customer. Existing technology and near-term advanced technology were surveyed to achieve the required design strategies. In the process, advanced nozzles, advanced turbomachinery, valves, controls, and operational procedures were evaluated. The integrated arrangement of three conventional bell nozzle thrust chambers with two advanced turbopump sets selected as the configuration meeting all requirements was rated significantly ahead of the other candidates, including the Aerospike and horizontal flow nozzle configurations.

    2017-02-01

    Biochemical circuits made of rationally designed DNA molecules are proofs of concept for embedding control within complex molecular environments. They hold promise for transforming the current technologies in chemistry, biology, medicine and material science by introducing programmable and responsive behaviour to diverse molecular systems. As the transformative power of a technology depends on its accessibility, two main challenges are an automated design process and simple experimental procedures. Here we demonstrate the use of circuit design software, combined with the use of unpurified strands and simplified experimental procedures, for creating a complex DNA strand displacement circuit that consists of 78 distinct species. We develop a systematic procedure for overcoming the challenges involved in using unpurified DNA strands. We also develop a model that takes synthesis errors into consideration and semi-quantitatively reproduces the experimental data. Our methods now enable even novice researchers to successfully design and construct complex DNA strand displacement circuits.

    2015-05-01

    Ultrasound-guided procedures are increasingly common in a variety of acute care settings, such as the operating room, critical care unit and emergency room. However, accurate judgment of needle tip position using traditional ultrasound technology is frequently difficult, and serious injury can result from inadvertently advancing beyond or through the target. Needle navigation is a recent innovation that allows the clinician to visualize the needle position and trajectory in real time as it approaches the target. A novel ultrasound machine has recently been introduced that is portable and designed for procedural guidance. The eZono 4000™ features an innovative needle navigation technology that is simple to use and permits the use of a wide range of commercially available needles, avoiding the inconvenience and cost of proprietary equipment. This article discusses this new ultrasound machine in the context of other currently available ultrasound machines featuring needle navigation.

    So far, the abuse of gene transfer technology in sport, so-called gene doping, is undetectable. However, recent studies in somatic gene therapy indicate that long-term presence of transgenic DNA (tDNA) following various gene transfer protocols can be found in DNA isolated from whole blood using conventional PCR protocols. Application of these protocols for the direct detection of gene doping would require almost complete knowledge about the sequence of the genetic information that has been transferred. Here, we develop and describe the novel single-copy primer-internal intron-spanning PCR (spiPCR) procedure that overcomes this difficulty. Apart from the interesting perspectives that this spiPCR procedure offers in the fight against gene doping, this technology could also be of interest in biodistribution and biosafety studies for gene therapeutic applications.

    Scientific advances in the creation of restorative biomaterials, in vitro cell culture technology, tissue grafting, tissue engineering, molecular biology and the human genome project provide the basis for the introduction of new technologies into dentistry. Non-vital infected teeth have long been treated with root canal therapy (for mature root apex) and apexification (for immature root apex), or doomed to extraction. Although successful, current treatments fail to re-establish healthy pulp tissue in these teeth. But, what if the non-vital tooth could be made vital once again? That is the hope offered by regenerative endodontics, an emerging field focused on replacing traumatized and diseased pulp with functional pulp tissue. Restoration of vitality of non-vital tooth is based on tissue engineering and revascularization procedures. The purpose of this article is to review these biological procedures and the hurdles that must be overcome to develop regenerative endodontic procedures.

    Fingerprint recognition technology is an important part of criminal investigations it is the basis of some security systems and an important tool of government operations such as the Immigration and Naturalization Services, registration procedures in the Armed Forces, and so forth. After the tragic events of September 11, 2001, the importance of reliable fingerprint recognition technology became even more obvious. In the current study, pressure-induced changes of distances between ridges of a fingerprint were measured. Using calibrated silicon pressure sensors we scanned the distribution of pressure across a finger pixel by pixel, and also generated maps of an average pressure distribution during fingerprinting. Emulating the fingerprinting procedure employed with widely used optical scanners, we found that on average the distance between ridges decreases by about 20% when a finger is positioned on a scanner. Controlled loading of a finger demonstrated that it is impossible to reproduce the same distribution of pressure across a given finger during repeated fingerprinting procedures.

    Rotating Lorentz-force flowmeters are a novel and useful technology with a range of applications in a variety of different industries. However, calibrating these flowmeters can be challenging, time-consuming, and expensive. In this paper, simple calibration procedures for rotating Lorentz-force flowmeters are presented. These procedures eliminate the need for expensive equipment, numerical modeling, redundant flowmeters, and system down-time. Finally, the calibration processes are explained in a step-by-step manner and compared to experimental results.

    Patient-specific virtual reality (VR) simulation is a technologic advancement that allows planning and practice of the carotid artery stenting (CAS) procedure before it is performed on the patient. The initial findings are reported, using this novel VR technique as a tool to optimize technical and nontechnical aspects of this complex endovascular procedure. In the angiography suite, the same interventional team performed the VR rehearsal and the actual CAS on the patient. All proceedings were recorded to allow for video analysis of team, technical, and nontechnical skills. Analysis of both procedures showed identical use of endovascular tools, similar access strategy, and a high degree of similarity between the angiography images. The total procedure time (24.04 vs 60.44 minutes), fluoroscopy time (11.19 vs 21.04 minutes), and cannulation of the common carotid artery (1.35 vs 9.34) took considerably longer in reality. An extensive questionnaire revealed that all team members found that the rehearsal increased the subjective sense of teamwork (4/5), communication (4/5), and patient safety (4/5). A VR procedure rehearsal is a practical and feasible preparatory tool for CAS and shows a high correlation with the real procedure. It has the potential to enhance the technical, nontechnical, and team performance. Further research is needed to evaluate if this technology can lead to improved outcomes for patients.

    The challenging timeline for DARPA's Orbital Express mission demanded a flexible, responsive, and (above all) safe approach to mission planning. Because the mission was a technology demonstration, pertinent planning information was learned during actual mission execution. This information led to amendments to procedures, which led to changes in the mission plan. In general, we used the ASPEN planner scheduler to generate and validate the mission plans. We enhanced ASPEN to enable it to reason about uncertainty. We also developed a model generator that would read the text of a procedure and translate it into an ASPEN model. These technologies had a significant impact on the success of the Orbital Express mission.

    Increasing the efficiency of the technological operations of blank production is closely related to the computer-aided technologies (CAx). On the one hand, the practical result represents reality exactly. On the other hand, the development procedure of new process development demands unrestricted resources, which are limited on the SMEs. The tools of CAx were successfully applied for development of new process of forging with torsion and result analysis as well. It was shown, that the theoretical calculations find the confirmation both in praxis and during numerical simulation. The mostly used constructional materials were under study. The torque angles were stated. The simulated results were evaluated by experimental procedure.

    This paper is devoted to the novel computer technologies employed in the studies of histological preparations. These technologies allow to visualize digital images, structurize the data obtained and store the results in computer memory. The authors emphasize the necessity to properly document digital images obtained during forensic-histological studies and propose the procedure for the formulation of electronic documents in conformity with the relevant technical and legal requirements. It is concluded that the use of digital images as a new study object permits to obviate the drawbacks inherent in the work with the traditional preparations and pass from descriptive microscopy to their quantitative analysis.

    Under contract with the Telemedicine & Advanced Technology Research Center (TATRC), Energid Technologies is developing a new XML-based language for describing surgical training exercises, the Surgical Simulation and Training Markup Language (SSTML). SSTML must represent everything from organ models (including tissue properties) to surgical procedures. SSTML is an open language (i.e., freely downloadable) that defines surgical training data through an XML schema. This article focuses on the data representation of the surgical procedures and organ modeling, as they highlight the need for a standard language and illustrate the features of SSTML. Integration of SSTML with software is also discussed.
