The present study evaluated opinions on SSA injection devices, including a recently approved lanreotide new device (lanreotide-ND, among nurses in Europe and the USA. Nurses injecting SSAs for at least three patients per year (n = 77 were interviewed regarding SSA devices. Device attributes were rated via questionnaire; nurses were then timed administering test injections with lanreotide-ND and octreotide long-acting release. The most important delivery system attributes were easy/convenient preparation and injection (ranked in the top five by 70% of nurses, low clogging risk (58%, and high product efficacy (55%. Compared with the octreotide long-acting release device, lanreotide-ND scored higher on 15/16 attributes, had shorter mean preparation and administration time (329 versus 66 seconds, respectively; P ≤ 0.01 and a higher overall preference score (70 versus 114, respectively; P ≤ 0.01. The five most important lanreotide-ND attributes were: prefilled device, confidence a full dose was delivered, low clogging risk, easy/convenient preparation and injection, and fast administration. These device features could lead to improvements in clinical practice and benefit patients/caregivers who administer SSAs at home.Keywords: nurse, somatostatin analog, device, lanreotide, octreotide

  6. Assistive acting movement therapy devices with pneumatic rotary-type soft actuators.

    Wilkening, André; Baiden, David; Ivlev, Oleg

    2012-12-01

    Inherent compliance and assistive behavior are assumed to be essential properties for safe human-robot interaction. Rehabilitation robots demand the highest standards in this respect because the machine interacts directly with weak persons who are often sensitive to pain. Using novel soft fluidic actuators with rotary elastic chambers (REC actuators), compact, lightweight, and cost-effective therapeutic devices can be developed. This article describes modular design and control strategies for new assistive acting robotic devices for upper and lower extremities. Due to the inherent compliance and natural back-drivability of pneumatic REC actuators, these movement therapy devices provide gentle treatment, whereby the interaction forces between humans and the therapy device are estimated without the use of expensive force/torque sensors. An active model-based gravity compensation based on separated models of the robot and of the individual patient's extremity provides the basis for effective assistive control. The utilization of pneumatic actuators demands a special safety concept, which is merged with control algorithms to provide a sufficient level of safeness and to catch any possible system errors and/or emergency situations. A self-explanatory user interface allows for easy, intuitive handling. Prototypes are very comfortable for use due to several control routines that work in the background. Assistive devices have been tested extensively with several healthy persons; the knee/hip movement therapy device is now under clinical trials at the Clinic for Orthopaedics and Trauma Surgery at the Klinikum Stuttgart.

  7. Far-infrared laser scattering in the ACT-I toroidal device

    A far-infrared laser scattering diagnostic has been built for the ACT-I toroidal device. The optical system uses a passively stabilized 447-μm CH3I laser. A polyethylene etalon is the beam splitter. The vacuum windows are plastic (TPX), which we found has the vacuum property Q 6.5 x 10-9 torr-liter/sec/cm2. Using paraboloidal and ellipsoidal mirrors for detection optics improves the signal strength and allows a better rf enclosure design for the detector. The diagnostic was tested by scattering from an ion Bernstein wave, a technique which can be used for ion temperature diagnostics

  8. Metalloproteinase MT1-MMP islets act as memory devices for podosome reemergence.

    El Azzouzi, Karim; Wiesner, Christiane; Linder, Stefan

    2016-04-11

    Podosomes are dynamic cell adhesions that are also sites of extracellular matrix degradation, through recruitment of matrix-lytic enzymes, particularly of matrix metalloproteinases. Using total internal reflection fluorescence microscopy, we show that the membrane-bound metalloproteinase MT1-MMP is enriched not only at podosomes but also at distinct "islets" embedded in the plasma membrane of primary human macrophages. MT1-MMP islets become apparent upon podosome dissolution and persist beyond podosome lifetime. Importantly, the majority of MT1-MMP islets are reused as sites of podosome reemergence. siRNA-mediated knockdown and recomplementation analyses show that islet formation is based on the cytoplasmic tail of MT1-MMP and its ability to bind the subcortical actin cytoskeleton. Collectively, our data reveal a previously unrecognized phase in the podosome life cycle and identify a structural function of MT1-MMP that is independent of its proteolytic activity. MT1-MMP islets thus act as cellular memory devices that enable efficient and localized reformation of podosomes, ensuring coordinated matrix degradation and invasion. PMID:27069022

  9. Rapid-acting closing device for pipe with liquid, especially liquid sodium

    A quick-acting closing device for liquid sodium pipes is described. The equipment has a closed space with a controlled atmosphere in which is placed a pull rod and the guide of the closure and the core of the electromagnet. On the pull rod, slidably connected to the electromagnet core is a knife mounted in a closed space. The knife has the shape of a hollow cylinder, at the end of the cylindrical part facing the partition wall there is a cutting edge which is split along the periphery. The closed space is separated from the liquid in the pipe by a partition wall, e.g., a membrane. The partition wall is connected on the side to the pull rod or to the closure guide formed into the shape of a collar and is vacuum-tight connected to it. At the opposite end at least two unequal-armed levers lean against the electromagnet core by the end of the longer arm. They are pivoted on the support which is connected to the bottom of the closed space. A recess in the le--vers engages a bell which supports a ring engaging a cylindrical spring. The inner space is fitted with a stop which deli--mitates the lift of the bell and the spring. (B.S.)

  10. Fixing a 510(K) Loophole: In Support of The Sound Devices Act of 2012

    Ho, Shuenn (Patrick)

    2014-01-01

    The current medical device regulatory system contains a dangerous loophole. While the voluntary recall of a harmful medical device removes it from the market, new devices that claim they are substantially equivalent to the recalled device can still reach the market through the 510(k) premarket notification process. Devices that have gained regulatory clearance in this fashion have caused considerable harm and are much more likely to be recalled for safety reasons as well. The recently propo...

  13. Optically-energized, emp-resistant, fast-acting, explosion initiating device

    Benson, David A.; Kuswa, Glenn W.

    1987-01-01

    Optical energy, provided from a remote user-operated source, is utilized to initially electrically charge a capacitor in a circuit that also contains an explosion initiating transducer in contact with a small explosive train contained in an attachable housing. Additional optical energy is subsequently supplied in a preferred embodiment to an optically responsive phototransistor acting in conjunction with a silicon controlled rectifer to release the stored electrical energy through the explosion initiating transducer to set off the explosive train. All energy transfers between the user and the explosive apparatus, either for charging it up or for setting it off, are conveyed optically and may be accomplished in a single optical fiber with coding to distinguish between specific optical energy transfers and between these and any extraneous signals.

  14. A balancing act: a phenomenological exploration of medical students' experiences of using mobile devices in the clinical setting

    Rashid-Doubell, F; Mohamed, S; Elmusharaf, K; O'Neill, C S

    2016-01-01

    Objective The aims of this study were to describe the experiences of senior students using mobile devices in a clinical setting while learning and interacting with clinical teachers, patients and each other, and to identify challenges that facilitated or impeded the use of such devices in the hospital. Design Interpretative phenomenology was chosen to guide our enquiry. Semi-structured interviews were conducted to examine the experiences of five senior medical students using mobile devices in the clinical setting. Setting and participants Senior medical students at an international medical school in the Middle East. Results Three main themes emerged from the data analysis: learning; professional identity and transitioning from student to doctor. The findings showed that using mobile devices in the clinical area as a learning tool was not a formalised process. Rather, it was opportunistic learning at the bedside and on occasion a source of distraction from clinical teaching. Students needed to negotiate relationships between themselves, the clinical teacher and patients in order to ensure that they maintained an acceptable professional image. Participants experienced and negotiated the change from student to doctor making them mindful of using their devices at the bedside. Conclusions Mobile devices are part of daily life for a medical student and there is a need to adapt medical education in the clinical setting, to allow the students to use their devices in a sensitive manner.

  15. Certification of an in-house manufactured translational couch unit for total body irradiation in accordance with the Medical Devices Act

    A new translational couch unit with extended potentials of dose optimization by variable velocity and a comfortable user interface with integrated patient administration was developed at the university clinic of Regensburg. Materials and Methods The concept and construction were elaborated in legal accordance with the in-house manufacture conditions mentioned in the German Medical Devices Act. In particular we have implemented a concept of functional safety based on a controller unit, an independent monitoring unit and self-testing procedures. Redundant safety relevant hard- and software components are continuously checked against each other. In case of any malfunction the translation movement and the linear accelerator are stopped. Gap-free continuation of the treatment will be possible after elimination of the cause of the interrupt. Results and Conclusion After the testing of the implemented functional safety features including the risk assessment and management, electrical safety, electromagnetic compatibility by accredited technical experts the translational couch system complies with the requirements of the Medical Devices Act and can be operated in terms of in-house application. The presented certification procedure can motivate other radiation departments to develop own systems for in-house usage. (orig.)

  16. Current Status of Community Pharmacies: Expectations as a Health Information Hub, the Enforcement of Revised Pharmaceutical and Medical Device Act, and a New Role as Stakeholders.

    Saito, Mitsuo

    2016-01-01

      According to the "Japan Revitalization Strategy" established in June 2013, "the government will promote better contributions of local pharmacies and pharmacists in encouraging self-medication of citizens by making pharmacies the community-based hub for providing information, giving advice on the proper use of non-prescription drugs, etc. and offering consultation and information service concerning health". In addition, the "Demanded Function and Ideal Form of Pharmacy," published in January 2014, requested a change, from pharmacies that specialized in dispensing medicines to pharmacies that serve as whole healthcare stations, providing pharmaceutical care based on patients' medical history, including the intake of dietary supplements. The medication fee was revised in April 2014 to enhance family pharmacy services and the management of pharmaceutical care. At that time, blood testing at a registered pharmacy was officially allowed under strict regulation. Revision of the "Pharmacist Law" in June 2014 included a request to pharmacists to provide pharmaceutical advice in addition to information. For the mitigation of drug-induced tragedies, the "Pharmaceutical Affairs Law" was amended to the "Pharmaceutical and Medical Device Act (PMD Act)" in November 2014, and proper use of medicines was imposed on healthcare professionals and other stakeholders. Patients were also requested to learn and understand the safety and harmful effects of medicines, and were requested to use medicines appropriately. As mentioned above, the status of pharmacies and pharmacists has dramatically changed in the past 2 years, and such changes over time are required. PMID:26831801

    Wave energy converters (WECs) and tidal energy converters (TECs) are only beginning to be deployed along the U.S. West Coast and in Hawai‘i, and a better understanding of their ecological effects on fish, particularly on special-status fish (e.g., threatened and endangered) is needed to facilitate project design and environmental permitting. The structures of WECs and TECs placed on to the seabed, such as anchors and foundations, may function as artificial reefs that attract reef-associated fishes, while the midwater and surface structures, such as mooring lines, buoys, and wave or tidal power devices, may function as fish aggregating devices (FADs), forming the nuclei for groups of fishes. Little is known about the potential for WECs and TECs to function as artificial reefs and FADs in coastal waters of the U.S. West Coast and Hawai‘i. We evaluated these potential ecological interactions by reviewing relevant information about fish associations with surrogate structures, such as artificial reefs, natural reefs, kelps, floating debris, oil and gas platforms, marine debris, anchored FADs deployed to enhance fishing opportunities, net-cages used for mariculture, and piers and docks. Based on our review, we postulate that the structures of WECs and TECs placed on or near the seabed in coastal waters of the U.S. West Coast and Hawai‘i likely will function as small-scale artificial reefs and attract potentially high densities of reef-associated fishes (including special-status rockfish species [Sebastes spp.] along the mainland), and that the midwater and surface structures of WECs placed in the tropical waters of Hawai‘i likely will function as de facto FADs with species assemblages varying by distance from shore and deployment depth. Along the U.S. West Coast, frequent associations with midwater and surface structures may be less likely: juvenile, semipelagic, kelp-associated rockfishes may occur at midwater and surface structures of WECs in coastal waters of

    2015-03-01

    We report a device to fill an array of small chemical reaction chambers (microreactors) with reagent and then seal them using pressurized viscous liquid acting through a flexible membrane. The device enables multiple, independent chemical reactions involving free floating intermediate molecules without interference from neighboring reactions or external environments. The device is validated by protein expressed in situ directly from DNA in a microarray of ~10,000 spots with no diffusion during three hours incubation. Using the device to probe for an autoantibody cancer biomarker in blood serum sample gave five times higher signal to background ratio compared to standard protein microarray expressed on a flat microscope slide. Physical design principles to effectively fill the array of microreactors with reagent and experimental results of alternate methods for sealing the microreactors are presented.

    2013-02-04

    We study heat transport in bulk/nanoporous/bulk silicon devices; we show that, despite bulk/nanoporous devices may act as thermal rectifiers, the non-linear aspects of their joint thermal conductance are not strong enough to lead to a negative differential thermal resistance, necessary to allow bulk/nanoporous/bulk Si devices to act as thermal transistors. Furthermore, we explicitly study the effective thermal conductivity of the mentioned devices for several temperatures, geometries, porosities, and pore size.

  10. Results availability for analgesic device, complex regional pain syndrome, and post-stroke pain trials: comparing the RReADS, RReACT, and RReMiT databases

    Dufka, Faustine L.; Munch, Troels; Dworkin, Robert H.; Rowbotham, Michael C.

    2015-01-01

    Abstract Evidence-based medicine rests on the assumption that treatment recommendations are robust, free from bias, and include results of all randomized clinical trials. The Repository of Registered Analgesic Clinical Trials search and analysis methodology was applied to create databases of complex regional pain syndrome (CRPS) and central post-stroke pain (CPSP) trials and adapted to create the Repository of Registered Analgesic Device Studies databases for trials of spinal cord stimulation (SCS), repetitive transcranial magnetic stimulation (rTMS), and transcranial direct current stimulation (tDCS). We identified 34 CRPS trials, 18 CPSP trials, 72 trials of SCS, and 92 trials of rTMS/tDCS. Irrespective of time since study completion, 45% of eligible CRPS and CPSP trials and 46% of eligible SCS and rTMS/tDCS trials had available results (peer-reviewed literature, results entered on registry, or gray literature); peer-reviewed publications could be found for 38% and 39%, respectively. Examining almost 1000 trials across a spectrum of painful disorders (fibromyalgia, diabetic painful neuropathy, post-herpetic neuralgia, migraine, CRPS, CPSP) and types of treatment, no single study characteristic consistently predicts unavailability of results. Results availability is higher 12 months after study completion but remains below 60% for peer-reviewed publications. Recommendations to increase results availability include supporting organizations advocating for transparency, enforcing existing results reporting regulations, enabling all primary registries to post results, stating trial registration numbers in all publication abstracts, and reducing barriers to publishing “negative” trials. For all diseases and treatment modalities, evidence-based medicine must rigorously adjust for the sheer magnitude of missing results in formulating treatment recommendations. PMID:25599303

  16. Thermonuclear device

    Purpose: To absorb fabrication errors in radial toroidal coils and a spacer and completely fill the gap between them by the provision of an expansion device between the coils and the supporting spacer by injecting fillers of a predetermined composition. Constitution: An expansion device comprising an expansion plate, packings inserted into grooves formed in the outer circumference of the expansion plate and a recessed pressure receiving plate is inserted between the wall surface of radial toroidal coils and a spacer for maintaining the gap between the toroidal coils. Then, filler comprising polyester resin and glass beads incorporated therein is injected from an injection aperture of the recessed pressure receiving plate having an exhaust aperture at the upper part. The filler is solidified and enables the fabrication error in the coils and the spacer to be absorbed. Since the gap between the coils and the spacer is completely filled, the tumbling force of the coils can surely be transmitted by way of the spacer to upper and lower racks. (Moriyama, K.)

  17. Scalable devices

    Krüger, Jens J.

    2014-01-01

    In computer science in general and in particular the field of high performance computing and supercomputing the term scalable plays an important role. It indicates that a piece of hardware, a concept, an algorithm, or an entire system scales with the size of the problem, i.e., it can not only be used in a very specific setting but it\\'s applicable for a wide range of problems. From small scenarios to possibly very large settings. In this spirit, there exist a number of fixed areas of research on scalability. There are works on scalable algorithms, scalable architectures but what are scalable devices? In the context of this chapter, we are interested in a whole range of display devices, ranging from small scale hardware such as tablet computers, pads, smart-phones etc. up to large tiled display walls. What interests us mostly is not so much the hardware setup but mostly the visualization algorithms behind these display systems that scale from your average smart phone up to the largest gigapixel display walls.

  19. PLASMA DEVICE

    Baker, W.R.

    1961-08-22

    A device is described for establishing and maintaining a high-energy, rotational plasma for use as a fast discharge capacitor. A disc-shaped, current- conducting plasma is formed in an axinl magnetic field and a crossed electric field, thereby creating rotational kinetic enengy in the plasma. Such energy stored in the rotation of the plasma disc is substantial and is convertible tc electrical energy by generator action in an output line electrically coupled to the plasma volume. Means are then provided for discharging the electrical energy into an external circuit coupled to the output line to produce a very large pulse having an extremely rapid rise time in the waveform thereof.

  6. Laser device

    Scott, Jill R.; Tremblay, Paul L.

    2007-07-10

    A laser device includes a target position, an optical component separated a distance J from the target position, and a laser energy source separated a distance H from the optical component, distance H being greater than distance J. A laser source manipulation mechanism exhibits a mechanical resolution of positioning the laser source. The mechanical resolution is less than a spatial resolution of laser energy at the target position as directed through the optical component. A vertical and a lateral index that intersect at an origin can be defined for the optical component. The manipulation mechanism can auto align laser aim through the origin during laser source motion. The laser source manipulation mechanism can include a mechanical index. The mechanical index can include a pivot point for laser source lateral motion and a reference point for laser source vertical motion. The target position can be located within an adverse environment including at least one of a high magnetic field, a vacuum system, a high pressure system, and a hazardous zone. The laser source and an electro-mechanical part of the manipulation mechanism can be located outside the adverse environment. The manipulation mechanism can include a Peaucellier linkage.

  11. Indirect Speech Acts

    李威

    2001-01-01

    Indirect speech acts are frequently used in verbal communication, the interpretation of them is of great importance in order to meet the demands of the development of students' communicative competence. This paper, therefore, intends to present Searle' s indirect speech acts and explore the way how indirect speech acts are interpreted in accordance with two influential theories. It consists of four parts. Part one gives a general introduction to the notion of speech acts theory. Part two makes an elaboration upon the conception of indirect speech act theory proposed by Searle and his supplement and development of illocutionary acts. Part three deals with the interpretation of indirect speech acts. Part four draws implication from the previous study and also serves as the conclusion of the dissertation.

  12. Spintronic devices as quantum networks

    Ionicioiu, R

    2005-01-01

    We explore spintronics from a quantum information (QI) perspective. We show that QI specific methods can be an effective tool in designing new devices. Using the formalism of quantum gates acting on spin and mode degrees of freedom, we provide a solution to a reverse engineering problem, namely how to design a device performing a given transformation between input and output. Among these, we describe an orientable Stern-Gerlach device and a new scheme to entangle two spins by transferring the entanglement from orbital to spin degrees of freedom. Finally, we propose a simple scheme to produce hyper-entangle electrons, i.e., particles entangled in both spin and mode degrees of freedom.

  14. Medical device labeling and advertising: an overview.

    Basile, E M; Armentrout, E; Reeves, K N

    1999-01-01

    The Food and Drug Administration (FDA) has the authority under the Federal Food, Drug, and Cosmetic Act (FDCA) to regulate the labeling of all medical devices. This statement, however, is not as simple as it appears. The regulation of medical device labels and labeling, closely linked to the advertisement of medical devices, is a dynamic area, and FDA is struggling to address the new issues that arise daily in this area. This article seeks to: 1) provide the background necessary to understand the current law and FDA's regulation of medical devices; 2) summarize the law and regulations governing medical devices; 3) define "intended use" and explain its importance; and 4) discuss several areas that are of particular interest to FDA, including promotion of uncleared or unapproved devices and uses, Internet promotion, press releases, and comparative claims.

    2005-01-01

    I show that the quantum measurement problem can be understood if the measurement is seen as a ``speech act'' in the sense of modern language theory. The reduction of the state vector is in this perspective an intersubjectice -- or better a-subjective -- symbolic process. I then give some perspectives on applications to the ``Mind-Body problem''.

  20. Long-acting contraceptive options.

    Kaunitz, A M

    1996-01-01

    Long-acting contraceptive methods are appropriate choices for women who prefer the convenience and high contraceptive efficacy of methods not requiring frequent compliance, and women for whom contraceptive doses of estrogen are either medically contraindicated or associated with persistent intolerable side effects. Annual pregnancy rates for the three methods described below are less than 1 per 100 woman-years. As currently formulated, levonorgestrel implants (Norplant) consist of six 34 x 2.4 mm soft plastic implants, each filled with 36 mg of crystalline levonorgestrel. Irregular and often persistent menstrual bleeding and spotting constitute the most important side effects experienced by and leading to method discontinuation in implant users. Implant removal is technically more difficult and time-consuming than insertion. Depot-medroxyprogesterone acetate (DMPA or Depo-Provera) is injected as an aqueous suspension of microcrystals. Intramuscular injection of 150 mg of DMPA results in more than 3 months of contraception. Irregular bleeding and spotting followed by amenorrhea, constitute the most importance side effects experienced by DMPA users. Because DMPA use can result in prolonged (but not permanent) infertility, DMPA is not an optimum contraceptive choice for women who may want to conceive in the next one or two years. The Copper T380A intrauterine device (IUD) provides reversible contraception for up to 10 years. IUDs act as contraceptives, not early abortafacients. Recent epidemiologic data indicate that long-term IUD use does not increase the occurrence of pelvic inflammatory disease. Heavier menstrual flow and cramps constitute the main side effects experienced by women using the copper IUD. Intrauterine device insertion and removal are accomplished during brief office-based procedures. PMID:8829701

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

  7. The Radiation Protection Act

    The new Radiation Protection Act (1988:220) entered into force in Sweden on July 1st, 1988. This book presents the Act as well as certain regulations connected to it. As previously, the main responsibility for public radiation protection will rest with one central radiation protection authority. According to the 1988 Act, the general obligations with regard to radiation protection will place a greater responsibility than in the past on persons carrying out activities involving radiation. Under the act, it is possible to adjust the licensing and supervisory procedures to the level of danger of the radiation source and the need for adequate competence, etc. The Act recognises standardised approval procedures combined with technical regulations for areas where the risks are well known. The Act contains several rules providing for more effective supervision. The supervising authority may in particular decide on the necessary regulations and prohibitions for each individual case. The possibilities of using penal provisions have been extended and a rule on the mandatory execution of orders has been introduced. The Ordinance on Radiation Protection (1988:293) designates the National Institute of Radiation Protection (SSI) as the central authority referred to in the Radiation Protection Act. The book also gives a historic review of radiation protection laws in Sweden, lists regulations issued by SSI and presents explanations of radiation effects and international norms in the area.

  11. Fast-acting self-healing metallic fuse.

    Schwartz, F. C.; Renton, C. A.; Rabinovici, B.

    1971-01-01

    Description of a fast-acting nonmechanical self-healing mercury fuse capable of protecting a high current circuit or device from overcurrent fault damages. Basically the self-healing fuse consists of two enclosed mercury reservoirs connected by a fine capillary tube filled with mercury that serves as the fusing element. It is pointed out that a better understanding of the energy conversion process involved in the operation of the device could help explore other device configurations (such as a tapering geometry and use of magnetic field to drive the arc into the fuse wall on inductive loads, etc.) and thus extend the range of capabilities for this type of protective device.

  6. The CEO's second act.

    Nadler, David A

    2007-01-01

    When a CEO leaves because of performance problems, the company typically recruits someone thought to be better equipped to fix what the departing executive couldn't--or wouldn't. The board places its confidence in the new person because of the present dilemma's similarity to some previous challenge that he or she dealt with successfully. But familiar problems are inevitably succeeded by less familiar ones, for which the specially selected CEO is not quite so qualified. More often than not, the experiences, skills, and temperament that yielded triumph in Act I turn out to be unequal to Act II's difficulties. In fact, the approaches that worked so brilliantly in Act I may be the very opposite of what is needed in Act II. The CEO has four choices: refuse to change, in which case he or she will be replaced; realize that the next act requires new skills and learn them; downsize or circumscribe his or her role to compensate for deficiencies; or line up a successor who is qualified to fill a role to which the incumbent's skills and interests are no longer suited. Hewlett-Packard's Carly Fiorina exemplifies the first alternative; Merrill Lynch's Stanley O'Neal the second; Google's Sergey Brin and Larry Page the third; and Quest Diagnostics' Ken Freeman the fourth. All but the first option are reasonable responses to the challenges presented in the second acts of most CEOs' tenures. And all but the first require a power of observation, a propensity for introspection, and a strain of humility that are rare in the ranks of the very people who need those qualities most. There are four essential steps executives can take to discern that they have entered new territory and to respond accordingly: recognition that their leadership style and approach are no longer working; acceptance of others' advice on why performance is faltering; analysis and understanding of the nature of the Act II shift; and, finally, decision and action.

  7. No 592 - Radiation Act

    This Act will enter into force on 1 January 1992. The scope of the Act is extensive as, in addition to ionizing radiation, it will also apply to activities involving exposure to natural radiation and non-ionizing radiation. Its purpose is to prevent and restrict harmful effects to health resulting from radiation. The basic principles of the Act are that the practice involving radiation should be justified; radiation protection should be optimized; and radiation doses should be as low as reasonably achievable. Licensed organisations using radiation will be responsible for the safety of the activity involving exposure to radiation and for having available the appropriate expertise to this effect. The required so-called safety licence provides the regulatory control to ensure that radiation is used sensibly, that the equipment and shields are technically acceptable and the operating personnel is competent, and that the radioactive waste is dealt with appropriately. The Radiation Act will also apply to nuclear activities within the scope of the 1987 Nuclear Energy Act

  9. The Clean Air Act

    The Clean Air Act amendments alter the complex laws affecting atmospheric pollution and at the same time have broad implications for energy. Specifically, the Clean Air Act amendments for the first time deal with the environmental problem of acid deposition in a way that minimizes energy and economic impacts. By relying upon a market-based system of emission trading, a least cost solution will be used to reduce sulfur dioxide (SO2) emissions by almost 40 percent. The emission trading system is the centerpiece of the Clean Air Act (CAA) amendments effort to resolve energy and environmental interactions in a manner that will maximize environmental solutions while minimizing energy impacts. This paper will explore how the present CAA amendments deal with the emission trading system and the likely impact of the emission trading system and the CAA amendments upon the electric power industry

  2. Inspection device in liquid

    The present invention provides an inspection device in PWR reactor core in which inspection operations are made efficient by stabilizing a posture of the device in front-to-back, vertical and left-to-right directions by a simple structure. When the device conducts inspection while running in liquid, the front and the back directions of the device main body are inspected using a visual device while changing the posture by operating a front-to-back direction propulsion device and a right-to-left direction propulsion device, and a vertical direction propulsion device against to rolling, pitching and yawing of the device main body. In this case, a spherical magnet moves freely in the gravitational direction in a vibration-damping fluid in a non-magnetic spherical shell following the change of the posture of the device main body, in which the vibrations due to the movement of the spherical magnet is settled by the vibration-damping fluid thereby stabilizing the posture of the device main body. At a typical inspection posture, the settling effect is enhanced by the attraction force between the spherical magnets in the spherical shell and each of magnetic force-attracted magnetic members disposed to the outer circumference of the shell, and the posture of the device main body can be confirmed in front-to-back, right-to-left and vertical directions by each of the posture confirming magnetic sensors.

    Forati, Ebrahim; Dill, Thyler; Sievenpiper, Dan

    2015-01-01

    The semiconductor channel in conventional microelectronic devices was successfully replaced with an optically triggered gas plasma channel. The combination of DC and laser-induced gas ionizations controls the conductivity of the channel, enabling us to realize different electronic devices such as transistors, switches, modulators, etc. A special micro-scale metasurface was used to enhance the laser-gas interaction, as well as combining it with DC ionization properly. Optical plasma devices benefit form the advantages of plasma/vacuum electronic devices while preserving most of the integrablity of semiconductor based devices.

  14. Smart portable rehabilitation devices

    Leahey Matt

    2005-07-01

    Full Text Available Abstract Background The majority of current portable orthotic devices and rehabilitative braces provide stability, apply precise pressure, or help maintain alignment of the joints with out the capability for real time monitoring of the patient's motions and forces and without the ability for real time adjustments of the applied forces and motions. Improved technology has allowed for advancements where these devices can be designed to apply a form of tension to resist motion of the joint. These devices induce quicker recovery and are more effective at restoring proper biomechanics and improving muscle function. However, their shortcoming is in their inability to be adjusted in real-time, which is the most ideal form of a device for rehabilitation. This introduces a second class of devices beyond passive orthotics. It is comprised of "active" or powered devices, and although more complicated in design, they are definitely the most versatile. An active or powered orthotic, usually employs some type of actuator(s. Methods In this paper we present several new advancements in the area of smart rehabilitation devices that have been developed by the Northeastern University Robotics and Mechatronics Laboratory. They are all compact, wearable and portable devices and boast re-programmable, real time computer controlled functions as the central theme behind their operation. The sensory information and computer control of the three described devices make for highly efficient and versatile systems that represent a whole new breed in wearable rehabilitation devices. Their applications range from active-assistive rehabilitation to resistance exercise and even have applications in gait training. The three devices described are: a transportable continuous passive motion elbow device, a wearable electro-rheological fluid based knee resistance device, and a wearable electrical stimulation and biofeedback knee device.

  9. New Medical Device Evaluation.

    Ikeda, Koji

    2016-01-01

    In this presentation, as a member of the Harmonization by Doing (HBD) project, I discuss the significance of regulatory science in global medical device development and our experience in the international collaboration process for medical devices. In Japan, most innovative medical therapeutic devices were previously developed and exported by foreign-based companies. Due to this device lag, Japanese had minimal opportunities for receiving treatment with innovative medical devices. To address this issue, the Japanese government has actively accepted foreign clinical trial results and promoted global clinical trials in projects such as HBD. HBD is a project with stakeholders from academia, regulatory authorities, and industry in the US and Japan to promote global clinical trials and reduce device lags. When the project started, medical device clinical trials were not actively conducted in Japan at not just hospitals but also at medical device companies. We started to identify issues under the concept of HBD. After 10 years, we have now become key members in global clinical trials and able to obtain approvals without delay. Recently, HBD has started promoting international convergence. Physicians and regulatory authorities play central roles in compiling guidelines for the clinical evaluation of medical device development, which will be a more active field in the near future. The guidelines compiled will be confirmed with members of academia and regulatory authorities in the United Sates. PMID:27040333

  6. Compound semiconductor device modelling

    Miles, Robert

    1993-01-01

    Compound semiconductor devices form the foundation of solid-state microwave and optoelectronic technologies used in many modern communication systems. In common with their low frequency counterparts, these devices are often represented using equivalent circuit models, but it is often necessary to resort to physical models in order to gain insight into the detailed operation of compound semiconductor devices. Many of the earliest physical models were indeed developed to understand the 'unusual' phenomena which occur at high frequencies. Such was the case with the Gunn and IMPATI diodes, which led to an increased interest in using numerical simulation methods. Contemporary devices often have feature sizes so small that they no longer operate within the familiar traditional framework, and hot electron or even quantum­ mechanical models are required. The need for accurate and efficient models suitable for computer aided design has increased with the demand for a wider range of integrated devices for operation at...

  10. Fabrication and Characterization of Suspended Carbon Nanotube Devices in Liquid

    Artyukhin, A; Stadermann, M; Stroeve, P; Bakajin, O; Noy, A

    2006-10-30

    Suspended carbon nanotube devices are a promising platform for future bio-electronic applications. Suspended carbon nanotube transistors have been previously fabricated in air; however all previous attempts to bring them into liquid failed. We analyze forces acting on the suspended nanotube devices during immersion into liquids and during device operation and show that surface tension forces acting on the suspended nanotubes during transfer into the liquid phase are responsible for the nanotube damage. We have developed a new strategy that circumvents these limitations by coating suspended nanotubes with a rigid inorganic shell in the gas phase. The coating reinforces the nanotubes and allows them to survive transfer through the interface. Subsequent removal of the coating in the solution phase restores pristine suspended nanotubes. We demonstrate that devices fabricated using this technique preserve their original electrical characteristics.

  2. Advanced underwater lift device

    Flanagan, David T.; Hopkins, Robert C.

    1993-01-01

    Flexible underwater lift devices ('lift bags') are used in underwater operations to provide buoyancy to submerged objects. Commercially available designs are heavy, bulky, and awkward to handle, and thus are limited in size and useful lifting capacity. An underwater lift device having less than 20 percent of the bulk and less than 10 percent of the weight of commercially available models was developed. The design features a dual membrane envelope, a nearly homogeneous envelope membrane stress distribution, and a minimum surface-to-volume ratio. A proof-of-concept model of 50 kg capacity was built and tested. Originally designed to provide buoyancy to mock-ups submerged in NASA's weightlessness simulators, the device may have application to water-landed spacecraft which must deploy flotation upon impact, and where launch weight and volume penalties are significant. The device may also be useful for the automated recovery of ocean floor probes or in marine salvage applications.

  12. Organic 'Plastic' Optoelectronic Devices

    Recent developments on conjugated polymer based photovoltaic diodes and photoactive organic field effect transistors (photOFETs) are discussed. The photophysics of such devices is based on the photoinduced charge transfer from donor type semiconducting conjugated polymers onto acceptor type conjugated polymers or acceptor molecules such as Buckminsterfullerene, C60. Potentially interesting applications include sensitization of the photoconductivity and photovoltaic phenomena as well as photoresponsive organic field effect transistors (photOFETs). Furthermore, organic polymeric/inorganic nanoparticle based 'hybrid' solar cells will be discussed. This talk gives an overview of materials' aspect, charge-transport, and device physics of organic diodes and field-effect transistors. Furthermore, due to the compatibility of carbon/hydrogen based organic semiconductors with organic biomolecules and living cells there can be a great opportunity to integrate such organic semiconductor devices (biOFETs) with the living organisms. In general the largely independent bio/lifesciences and information technology of today, can be thus bridged in an advanced cybernetic approach using organic semiconductor devices embedded in bio-lifesciences. This field of bio-organic electronic devices is proposed to be an important mission of organic semiconductor devices

  13. Reactor power control device

    The present invention provides a control device which can conduct scram and avoid lowering of the power of a nuclear power plant upon occurrence of earthquakes. Namely, the device of the present invention comprises, in addition to an existent power control device, (1) an earthquake detector for detecting occurrence and annihilation of earthquakes and (2) a reactor control device for outputting control rod operation signals and reactor core flow rate control signals depending on the earthquake detection signals from the detector, and reactor and plant information. With such a constitution, although the reactor is vibrated by earthquakes, the detector detects slight oscillations of the reactor by initial fine vibration waves as premonitory symptoms of serious earthquakes. The earthquake occurrence signals are outputted to the reactor control device. The reactor control device, receiving the signals, changes the position of control rods by way of control rod driving mechanisms to make the axial power distribution in the reactor core to a top peak type. As a result, even if the void amount in the reactor core is reduced by the subsequent actual earthquakes, since the void amount is moved, effects on the increase of neutron fluxes by the actual earthquakes is small.

  14. JK '98: Acting responsibly

    For the first time, a paper delivered at the Annual Nuclear Conference was presented by two authors, the CEO of Bayernwerk AG, Dr. Otto Majewski, and the CEO of the Power Generation Division (KWU) of Siemens AG, Adolf Huettl, reflecting the operators' and the vendors' points of view about the present situation of nuclear power use in Germany and the need to maintain its share in the energy mix. The events associated with shipments of casks for radioactive waste have rekindled the debate about the responsibility of the peaceful use of nuclear power in the nuclear opposition camp. That debate needs to be put back on a factual basis. If no consensus could be achieved now about the use of nuclear power as a whole, at least consensus had to be reached about the future approach to spent fuel and waste management. From the outset, the nuclear industry has shown a high degree of responsibility, developing concepts of using uranium as an energy source in an economically viable and responsible way. It is showing responsibility also in making provision for the future. The safe and economically successful operation of today's nuclear power plants is an important reason for developing new reactor concepts. That development of new rector lines depends critically on the preservation and advancement of specialized knowledge. Know-how needs to be preserved and developed further not only for future nuclear power plants but also for the plants existing now, which still have service lives of several decades. Sustainable energy supply requires all sources of energy to be exploited, especially those which do not generate carbon dioxide. All the options currently known must be kept open and preserved, respectively, for coming generations. Acting responsibly means adding to the choices available. (orig.)

  15. [Euthanasia and medical act].

    2011-05-01

    Right to life -as the prohibition of intentionally and arbitrarily taking life, even with authorization of the concerned one- is an internationally recognized right. In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.

  19. Cataphoric devices in spoken discourse.

    Gernsbacher, M A; Jescheniak, J D

    1995-08-01

    We propose that speakers mark key words with cataphoric devices. Cataphoric devices are counterparts to anaphoric devices: Just as anaphoric devices enable backward reference, cataphoric devices enable forward reference. And just as anaphoric devices mark concepts that have been mentioned before, cataphoric devices mark concepts that are likely to be mentioned again. We investigated two cataphoric devices: spoken stress and the indefinite this. Our experiments demonstrated three ways that concepts marked by cataphoric devices gain a privileged status in listeners' mental representations: Cataphoric devices enhance the activation of the concepts that they mark; cataphoric devices suppress the activation of previously mentioned concepts; and cataphoric devices protect the concepts that they mark from being suppressed by subsequently mentioned concepts.

  20. Diamond Electronic Devices

    For high-power and high-voltage applications, silicon is by far the dominant semiconductor material. However, silicon has many limitations, e.g. a relatively low thermal conductivity, electric breakdown occurs at relatively low fields and the bandgap is 1.1 eV which effectively limits operation to temperatures below 175 deg.n C. Wide-bandgap materials, such as silicon carbide (SiC), gallium nitride (GaN) and diamond offer the potential to overcome both the temperature and power handling limitations of silicon. Diamond is the most extreme in this class of materials. By the fundamental material properties alone, diamond offers the largest benefits as a semiconductor material for power electronic applications. On the other hand, diamond has a problem with a large carrier activation energy of available dopants which necessitates specialised device concepts to allow room temperature (RT) operation. In addition, the role of common defects on the charge transport properties of diamond is poorly understood. Notwithstanding this, many proof-of-principle two-terminal and three-terminal devices have been made and tested. Two-terminal electronic diamond devices described in the literature include: p-n diodes, p-i-n diodes, various types of radiation detectors, Schottky diodes and photoconductive or electron beam triggered switches. Three terminal devices include e.g. MISFETs and JFETs. However, the development of diamond devices poses great challenges for the future. A particularly interesting way to overcome the doping problem, for which there has been some recent progress, is to make so-called delta doped (or pulse-doped) devices. Such devices utilise very thin (∼1 nm) doped layers in order to achieve high RT activation.

  1. Diamond Electronic Devices

    Isberg, J.

    2010-11-01

    For high-power and high-voltage applications, silicon is by far the dominant semiconductor material. However, silicon has many limitations, e.g. a relatively low thermal conductivity, electric breakdown occurs at relatively low fields and the bandgap is 1.1 eV which effectively limits operation to temperatures below 175° C. Wide-bandgap materials, such as silicon carbide (SiC), gallium nitride (GaN) and diamond offer the potential to overcome both the temperature and power handling limitations of silicon. Diamond is the most extreme in this class of materials. By the fundamental material properties alone, diamond offers the largest benefits as a semiconductor material for power electronic applications. On the other hand, diamond has a problem with a large carrier activation energy of available dopants which necessitates specialised device concepts to allow room temperature (RT) operation.

  9. Act local, think global

    Tip O'Neill, one of the grand old men of modem US politics, once famously remarked that all politics is local. Like most politicians who succeed on the national stage - and not just in the US - it was a truth he never lost sight of. What is true for politicians is equally true in the communications business. We may increasingly live in a global village, but successful companies - even multi-nationals - forget the importance of local and regional public relations at their peril. Think of Douglas Ivester, the CEO of Coca-Cola at the time of the 1999 Belgian contamination scandal, who allegedly reacted to first reports of the crisis by asking: 'Where the hell is Belgium?' A more appropriate question today - several years after Coke's share price toppled and the CEO was unceremoniously sacked - might be: 'Who the hell is Douglas Nester?' But - to adapt another famous phrase - the fact that communications (and marketing) professionals still need to 'act local' as much as ever before should not blind us to the growing need to 'think global'. In the nuclear industry, as in the world economy generally, increasing global integration is a reality, as are the international nature of the news media and the increasingly global nature of the anti-nuclear pressure groups. Indeed, it was the growing need for a truly global information network to counter these trends, by increasing the overall speed and accuracy of the worldwide nuclear information flow, that led the nuclear community to establish NucNet in 1991. So where exactly is the line between local and regional nuclear communications on the one hand, and global communications on the other? Is there one spin for a regional audience, and another for a global audience? This presentation proposes some guiding principles, by examining the response of nuclear communicators world-wide to the new communications agenda imposed in the wake of the September 11th suicide attacks in the US. NucNet President Doug McRoberts and Executive

  10. Condensate filtering device

    In a condensate filtering device of a nuclear power plant, a water collecting pipe is disposed over the entire length, an end of a hollow thread is in communication with the water collecting pipe and secured. If the length of the water collecting pipe is extended, a filtering device of an optional length can be obtained irrespective of the length of the hollow thread. Therefore, since there is no need to connect units upon constituting a module, flow of cleaning gases is not restricted at connection portions. Accordingly, even if the volume of the device is increased by the extension of the module, the working life of the module is not degraded. (T.M.)

  11. Endoscopic Devices for Obesity.

    Sampath, Kartik; Dinani, Amreen M; Rothstein, Richard I

    2016-06-01

    The obesity epidemic, recognized by the World Health Organization in 1997, refers to the rising incidence of obesity worldwide. Lifestyle modification and pharmacotherapy are often ineffective long-term solutions; bariatric surgery remains the gold standard for long-term obesity weight loss. Despite the reported benefits, it has been estimated that only 1% of obese patients will undergo surgery. Endoscopic treatment for obesity represents a potential cost-effective, accessible, minimally invasive procedure that can function as a bridge or alternative intervention to bariatric surgery. We review the current endoscopic bariatric devices including space occupying devices, endoscopic gastroplasty, aspiration technology, post-bariatric surgery endoscopic revision, and obesity-related NOTES procedures. Given the diverse devices already FDA approved and in development, we discuss the future directions of endoscopic therapies for obesity. PMID:27115879

  12. Pendulum detector testing device

    A detector testing device is described which provides consistent, cost-effective, repeatable results. The testing device is primarily constructed of PVC plastic and other non-metallic materials. Sensitivity of a walk-through detector system can be checked by: (1) providing a standard test object simulating the mass, size and material content of a weapon or other contraband, (2) suspending the test object in successive positions, such as head, waist and ankle levels, simulating where the contraband might be concealed on a person walking through the detector system; and (3) swinging the suspended object through each of the positions, while operating the detector system and observing its response. The test object is retained in a holder in which the orientation of the test device or target can be readily changed, to properly complete the testing requirements. 5 figs

  13. ALS insertion devices

    The Advanced Light Source (ALS), the first US third generation synchrotron radiation source, is currently under construction at the Lawrence Berkeley Laboratory. The low-emittance, 1.5 GeV electron storage ring and the insertion devices are specifically designed to produce high brightness beams in the UV to soft X-Ray range. The planned initial complement of insertion devices includes four 4.6 m long undulators, with period lengths of 3.9 cm, 5.0 cm (2) and 8.0 cm, and a 2.9 m long wiggler of 16 cm period length. Undulator design is well advanced and fabrication has begun on the 5.0 cm and 8.0 cm period length undulators. This paper discusses ALS insertion device requirements; general design philosophy; and design of the magnetic structure, support structure/drive systems, control system and vacuum system. 18 refs., 9 figs., 5 tabs

  14. Control rod operation device

    Purpose: To reduce operator's operation burdens in the low power state, while moderate his mental burdens upon high power state for the operation of control rod operation device. Constitution: Coordinate of main control rods to be operated, aimed insertion and withdrawal positions and velocity are calculated by the control rod operation sequence and the control rod worth table, to output a control rod selection signal and a control rod operation signal. The control rod operation device conducts extraction or insertion of control rods by these signals. In this way, the operator can automatically operate the control rods by merely manipulating the control rod operation device, by which the operator's operation burden can be reduced in low power state. Further, since the selection of the control rods, the operation speed, etc. are judged by an electronic computer also upon high reactor power state, operator's metal burdens can be moderated. (Kamimura, M.)

  15. Drive of especially quick-acting valve for nuclear power

    The quick-acting valve drive consists of two branches coupled via a control joint, with their outer ends fitted in fixing joints. The active end of a flexible control element is connected to the control joint. In normal operation, the valve piston is in the terminal position. The flexible element is compressed and retained in the position by air pressure. If the valve is to be closed, compressed air is supplied in a control cylinder from the other side. In the event of air supply failure, the compressed air kept in the valve body can be used for several settings. When the supply is exhausted, the flexible element can be used for emergency valve closing. The device allows achieving high control forces of quick-acting valves in emergencies while keeping down the size of the device and featuring low consumption of compressed air at normal operation.

  16. Evolution of Growth Hormone Devices: Matching Devices with Patients.

    Raimer-Hall, Dawn; Shea, Heidi Chamberlain

    2015-01-01

    Self-injection of growth hormone (GH) by children with GH deficiency can be problematic. They may have difficulty manipulating injection devices or preparing medication, and injections can be painful and create anxiety. Adherence to daily GH injections optimizes treatment benefit. Studies indicate that injection pens or needle-free devices enable easy self-injection by children, minimize medication reconstitution and storage requirements, and reduce injection pain. Newer GH delivery devices potentially encourage improved patient adherence. Reviewing features of GH devices will help nurses decide which GH device best fits the needs and abilities of pediatric patients. We searched recent medical literature about GH device development, about device-associated patient preferences and treatment adherence, and comparisons among GH devices. We concluded that improved awareness of the strengths and limitations of GH devices will enable nurses to guide families in selecting and using GH devices, improving adherence and outcomes, and helping children reach full growth potential.

    2013-04-01

    A single-electron tunneling (SET) device with a nanoscale central island that can move with respect to the bulk sourceand drain electrodes allows for a nanoelectromechanical (NEM) coupling between the electrical current through the device and the mechanical vibrations of the island. Although the electromechanical "shuttle" instability and the associated phenomenon of single-electron shuttling were predicted more than 15 years ago, both theoretical and experimental studies of NEM-SET structures are still carried out. New functionalities based on quantum coherence, Coulomb correlations and coherent electron-spin dynamics are still of particular interest. In this article we present a short review of recent activities in this area.

    2015-08-01

    Graphene-metals interfaces are investigated in many subject areas both applicative and speculative. The interest mainly stems from the possibility for CVD synthesis of large area graphene on metals. In this case the metal acts as a catalyst for complete dehydrogenetaion of hydrocarbon precursors that leaves carbon behind at the surface. Such bilayer are also very appealing for surface plasmon resonance devices, since graphene acts both as a protective layer and biorecognition element. Several pairs of graphene-metal interfaces have been studied in terms of SPR performance and physicalchemical properties at the interface. With regard to this last aspect, NEXAFS spectroscopy is a powerful method to study single-, double-, and few- layers graphene and to illustrate any evolution of the electronic states.

  10. Forced Ion Migration for Chalcogenide Phase Change Memory Device

    Campbell, Kristy A (Inventor)

    2013-01-01

    Non-volatile memory devices with two stacked layers of chalcogenide materials comprising the active memory device have been investigated for their potential as phase-change memories. The devices tested included GeTe/SnTe, Ge2Se3/SnTe, and Ge2Se3/SnSe stacks. All devices exhibited resistance switching behavior. The polarity of the applied voltage with respect to the SnTe or SnSe layer was critical to the memory switching properties, due to the electric field induced movement of either Sn or Te into the Ge-chalcogenide layer. One embodiment of the invention is a device comprising a stack of chalcogenide-containing layers which exhibit phase-change switching only after a reverse polarity voltage potential is applied across the stack causing ion movement into an adjacent layer and thus "activating" the device to act as a phase-change random access memory device or a reconfigurable electronics device when the applied voltage potential is returned to the normal polarity. Another embodiment of the invention is a device that is capable of exhibiting more than two data states.

  11. Theoretical aspects of Dust in fusion devices

    It is known that micro-particles (dust) exist in fusion devices. However, an impact of dust on plasma contamination, material migration, and performance of fusion devices is still under debate. In burning plasma experiments like ITER dust can also pose safety problems related to it's chemical activity, toxicity, tritium retention, and radioactive content. In order to address all these issues we need to understand the physics of dust generation, dynamics, and transport. In this paper, the results of recent theoretical studies of dust in fusion plasmas are reviewed. Different aspects of the physics of dust in fusion plasmas, including the processes of dust generation, charging, heating, destruction, spinning, forces acting on dust, dust collision with material walls, etc are discussed. The numerical models of these processes have been incorporated into the dust transport code DUSTT, which is capable of tracking of dust particles in fusion devices in 3D geometry. The results of the simulations of dust particle dynamics, transport, and the impact on edge plasma performance are considered. The latest results on nonlinear interactions of dust grain with tokamak plasma as well as remaining gaps in the understanding of physics of dust in fusion devices are discussed (copyright 2010 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

The outer frame has four outer frame legs, and each of the outer frame legs is equipped with a sucker at the top end. The inner frame has four inner frame legs each equipped with a sucker at the top end. The outer frame legs and the inner frame legs are each connected with the outer frame and the inner frame by the air cylinder. The outer and the inner frame legs can be elevated or lowered (or extended or contracted) by the air cylinder. The sucker is connected with a jet pump-type negative pressure generator. The device can run and move by repeating attraction and releasing of the outer frame legs and the inner frame legs alternately while maintaining the posture of the inspection device stably. (I.N.)

  13. Neutron measuring device

    The device of the present invention concerns measurement for neutrons in a tokamak type thermonuclear device and it can measure total amount of generated neutrons accurately throughout the operation period even if an error is caused in counted values by plasma disruption. That is, the device comprises (1) a means for detecting presence or absence of occurrence of plasma disruption and the time for the initiation of the occurrence, (2) a first data processing means for processing detection signals, (3) a means for detecting neutrons generated in plasmas and (4) a second data processing means for calculating integrated values for the number of neutrons generated from the start to the completion of electric discharge when no disruption occurs and calculating integrated values for the number of generated neutrons from the start of electric discharge to the time at the initiation of occurrence of the disruption when disruption is present. In the thus constituted device, even if an error is caused by frequent occurrence of plasma disruption, total time integrated amount of neutrons generated in the plasmas can be measured accurately.

  15. Device Oriented Project Controller

    Dalesio, Leo; Kraimer, Martin

    2013-11-20

    This proposal is directed at the issue of developing control systems for very large HEP projects. A de-facto standard in accelerator control is the Experimental Physics and Industrial Control System (EPICS), which has been applied successfully to many physics projects. EPICS is a channel based system that requires that each channel of each device be configured and controlled. In Phase I, the feasibility of a device oriented extension to the distributed channel database was demonstrated by prototyping a device aware version of an EPICS I/O controller that functions with the current version of the channel access communication protocol. Extensions have been made to the grammar to define the database. Only a multi-stage position controller with limit switches was developed in the demonstration, but the grammar should support a full range of functional record types. In phase II, a full set of record types will be developed to support all existing record types, a set of process control functions for closed loop control, and support for experimental beam line control. A tool to configure these records will be developed. A communication protocol will be developed or extensions will be made to Channel Access to support introspection of components of a device. Performance bench marks will be made on both communication protocol and the database. After these records and performance tests are under way, a second of the grammar will be undertaken.

  1. Emergency core cooling device

    The present invention provides an emergency core cooling device without using a reactor core spray device, in which the reactor core of a BWR type reactor is cooled effectively and certainly by flooding of the reactor core. That is, the emergency core cooling device comprises a high pressure core water injection system as an emergency core cooling system (ECCS) for cooling the inside of the reactor core upon loss of coolants accident (LOCA). By means of the high pressure core water injection system, water is injected from a condensate storage vessel or a suppression pool to the inside of the reactor core shroud upon LOCA. Accordingly, the reactor core is cooled effectively by reactor core flooding. In this device, cooling water can be injected to the inside of the reactor core shroud by means of the high pressure core injection system upon LOCA in which the coolants are discharged from the outside of the reactor core shroud. On the other hand, upon LOCA in which the coolants are discharged from the inside of the reactor core shroud, the cooling water can be supplied to the reactor core by means of a cooling system upon reactor isolation which injects water to the outside of the reactor core or a low pressure water injection system. (I.S.)

  2. Tritium removing device

    Tritium-containing gases in a reactor container are discharged to a gas pressurizer and the gases pressurized there are sent to the primary side of a tritium separation device under a high or low pressure. Polyimide polymer separation membranes having selective permeability to elemental tritium and tritium vapor are coated in the tritium separation device. The separation device is divided into primary and secondary sides by the separation membranes and the pressure in the secondary side is lowered by a vacuum pump, etc. Tritium contained in the tritium-containing gases passes through the separation membranes selectively to be moved into the secondary side. Accordingly, tritium is treated in the elemental form and equipments for regeneration such as an adsorption column, etc. are no more necessary and the space can be saved due to minimization of the removing device. Further, since tritium can be removed continuously without storing a great amount of tritium, it is preferable in view of safety. (T.M.)

  11. The grays of medical device color additives.

    Seidman, Brenda

    2014-01-01

    The United States' medical device color additive regulations are unknown to some, and confusing to many. This article reviews statutory language on color additives in the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended, including the Delaney Clause on carcinogenicity; color additive regulatory language as it relates to medical devices in Title 21 of the Code of Federal Regulations (C.F.R.), Parts 70-82; reports on the Food and Drug Administration's (FDA's) likely current and historical practices in dealing with color additives in medical devices; and speculates on what may have given rise to decades of seemingly ad hoc color additives practices, which may now be difficult to reconstruct and satisfactorily modify. Also addressed is the Center for Devices and Radiological Health's (CDRH's) recent publicly-vetted approach to color additives in Section 7 of its April 2013 draft guidance, Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," which the author concludes is a change in the right direction, but which, at least in its current draft form, is not a fix to the CDRH's color additives dilemma. Lastly, the article suggests what the CDRH might consider in further developing a new approach to color additives. Such an approach would treat color additives as if they were any other potentially toxic group of chemicals, and could be fashioned in such a way that the CDRH could still satisfy the broad aspects of Congressional color additives mandates, and.yet be consistent with ISO 10993. In doing this, the CDRH would need to recommend a more directed use of its Quality System Regulation, 21 C.F.R. Part 820, for material and vendor qualification and validation in general; approach Congress for needed statutory changes; or make administrative changes. In order for any approach to be successful, whether it is a new twist on past practices, or an entirely new path forward, the FDA must, to the best of its

  18. Radioactive waste processing device

    Liquid wastes are supplied to a ceramic filter to conduct filtration. In this case, a device for adding a powdery inorganic ion exchanger is disposed to the upstream of the ceramic filter. When the powdery inorganic ion exchanger is charged to the addition device, it is precoated to the surface of the ceramic filter, to conduct separation of suspended matters and separation of ionic nuclides simultaneously. Liquid wastes returned to a collecting tank are condensed while being circulated between the ceramic filter and the tank and then contained in a condensation liquid waste tank. With such a constitution, both of radioactive nuclides accompanied by suspended matters in the radioactive liquid wastes and ionic nuclides can be captured efficiently. (T.M.)

    2015-03-01

    The growing power of imaging and computing power of smartphones is creating the possibility of converting your smartphone into a high power pocket microscopy system. High quality miniature microscopy lenses attached to smartphone are typically made with glass or plastics that can only be produce at low cost with high volume. To revise the paradigm of microscope lenses, we devised a simple droplet lens fabrication technique that which produces low cost and high performance lens. Each lens is integrated into thin 3-D printed holder with complimentary light emitted diode (LEDs) that clips onto majority of smartphones. The integrated device converts a smartphone into a high power optical microscope/dermatoscope at around $2. This low cost device has wide application in a multitude of practical uses such as material inspection, dermascope and educational microscope.

  1. Microelectromechanical reprogrammable logic device

    Hafiz, M. A. A.; Kosuru, L.; Younis, M. I.

    2016-03-01

    In modern computing, the Boolean logic operations are set by interconnect schemes between the transistors. As the miniaturization in the component level to enhance the computational power is rapidly approaching physical limits, alternative computing methods are vigorously pursued. One of the desired aspects in the future computing approaches is the provision for hardware reconfigurability at run time to allow enhanced functionality. Here we demonstrate a reprogrammable logic device based on the electrothermal frequency modulation scheme of a single microelectromechanical resonator, capable of performing all the fundamental 2-bit logic functions as well as n-bit logic operations. Logic functions are performed by actively tuning the linear resonance frequency of the resonator operated at room temperature and under modest vacuum conditions, reprogrammable by the a.c.-driving frequency. The device is fabricated using complementary metal oxide semiconductor compatible mass fabrication process, suitable for on-chip integration, and promises an alternative electromechanical computing scheme.

  2. Internal pump monitoring device

    In the present invention, a thermometer is disposed at the upper end of an internal pump casing of a coolant recycling system in a BWR type reactor to detect leakage of reactor water thereby ensuring the improvement of reliability of the internal pump. Namely, a thermometer is disposed, which can detect temperature elevation occurred when water in the internal pump leaked from a reactor pressure vessel passes through the gap between a stretch tube and an upper end of the pump casing. Signals from the thermometer are transmitted to a signal processing device by an instrumentation cable. The signal processing device generates an alarm when the temperature signal exceeds a predetermined value and announces that leakage of reactor water occurs in the internal pump. Since the present invention can detect the leakage of the reactor water in the pump casing in an early stage, it can contribute to the improvement of the safety and reliability of the internal pump. (I.S.)

  3. Anti-gravity device

    Palsingh, S. (Inventor)

    1975-01-01

    An educational toy useful in demonstrating fundamental concepts regarding the laws of gravity is described. The device comprises a sphere 10 of radius r resting on top of sphere 12 of radius R. The center of gravity of sphere 10 is displaced from its geometrical center by distance D. The dimensions are so related that D((R+r)/r) is greater than r. With the center of gravity of sphere 10 lying on a vertical line, the device is in equilibrium. When sphere 10 is rolled on the surface of sphere 12 it will return to its equilibrium position upon release. This creates an illusion that sphere 10 is defying the laws of gravity. In reality, due to the above noted relationship of D, R, and r, the center of gravity of sphere 10 rises from its equilibrium position as it rolls a short distance up or down the surface of sphere 12.

  6. Thin film device applications

    Kaur, Inderjeet

    1983-01-01

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

  7. Particle capture device

    Jayne, John T.; Worsnop, Douglas R.

    2016-02-23

    In example embodiments, particle collection efficiency in aerosol analyzers and other particle measuring instruments is improved by a particle capture device that employs multiple collisions to decrease momentum of particles until the particles are collected (e.g., vaporized or come to rest). The particle collection device includes an aperture through which a focused particle beam enters. A collection enclosure is coupled to the aperture and has one or more internal surfaces against which particles of the focused beam collide. One or more features are employed in the collection enclosure to promote particles to collide multiple times within the enclosure, and thereby be vaporized or come to rest, rather than escape through the aperture.

  8. Incore inspection device

    The device of the present invention can inspect surfaces of equipments in reactor water in a nuclear reactor in a state of atmospheric air. Namely, an inspection device is movable forwardly and backwardly in a water-proof vessel. An annular sucker with pleats is disposed to the outer side of a lid of the water-proof vessel. A television camera for an under water monitoring is disposed to the inner side of the lid of the water-proof vessel by way of a partitioning wall with lid. Transferring screws are disposed at the back and on the side of the water-proof vessel. In the device having such a constitution, (1) the inside of the water-proof vessel is at first made water-tight by closing the partitioning wall with lid, (2) the back and the side screws are operated by the guide of the underwater monitoring television camera, to transfer the water-proof vessel to the surface of the reactor core to be inspected, (3) the annular sucker with pleats is urged on the surface to be inspected by the back screw, to fix the water-proof vessel, (4) reactor water in a space of the annular sucker with pleats is discharged and replaced with air, and (5) the lid of the partition wall with lid is opened and the inspection device is disposed at a position of the underwater monitoring television camera, to inspect the surface to be inspected in a state of atmospheric air.

  16. Memristor: the illusive device

    Salama, Khaled N.

    2012-05-03

    The memristor (M) is considered to be the fourth two-terminal passive element in electronics, alongside the resistor (R), the capacitor (C), and the inductor (L). Its existence was postulated in 1971 but its first implementation was reported in 2008. Where was it hiding all that time and what can we do with it? Come and learn how the memristor completes the roster of electronic devices much like a missing particle that physicists seek to complete their tableaus.

  1. Incore instrument device

    An incore instrument device has an integrally disposed touch panel having a function of displaying an operation indication method such as for setting of conditions for incore measurement and information processing and results of the incore measurement and a function capable of conducting operation indication such as for setting conditions and information processing for incore measurement relative to a control section upon touching an information position on a displayed information. In addition, an information processing section comprising a man-machine function program formed so as to recognize the content of the operation indication for the incore measurement by touching and let the control section to conduct it is disposed to the outside by way of a communication interface. In addition, a programming device is disposed for forming and rewriting the program of the man-machine function relative to the information processing section. Then, when various indication operations are conducted upon performing incore measurement, a view point can be concentrated to one predetermined point thereby enabling to improve the operationability without danger. In addition, the programming of the man-machine function does not apply unnecessary load to the control section in the incore instrumentation device. (N.H.)

  2. Submarine inspection device

    The device of the present invention can confirm the assembly number of a fuel assembly in a pool and detect the head of an inserted material by a screen an image. That is, a submarine object is caused to swim by remote control by using a control device. A float which is floating on the water is disposed above the submarine object. A winch is disposed to the float for winding a rope such as a wire. The rope of the winch is connected to the submarine object. A TV camera is disposed to the float for photographing the submarine object. With such a constitution, the length of the rope can be controlled by the winch to restrict the moving range of the submarine object. This can prevent the submarine object from colliding against a fuel assembly or dropping. In addition, the position of the submarine object, which has been confirmed so far by a compass, a depth-sounding device and an image of TV camera appended to the submarine object, can be detected by the television images of the float extremely simply. (I.S.)

  3. Reactor water sampling device

    The present invention concerns a reactor water sampling device for sampling reactor water in an in-core monitor (neutron measuring tube) housing in a BWR type reactor. The upper end portion of a drain pipe of the reactor water sampling device is attached detachably to an in-core monitor flange. A push-up rod is inserted in the drain pipe vertically movably. A sampling vessel and a vacuum pump are connected to the lower end of the drain pipe. A vacuum pump is operated to depressurize the inside of the device and move the push-up rod upwardly. Reactor water in the in-core monitor housing flows between the drain pipe and the push-up rod and flows into the sampling vessel. With such a constitution, reactor water in the in-core monitor housing can be sampled rapidly with neither opening the lid of the reactor pressure vessel nor being in contact with air. Accordingly, operator's exposure dose can be reduced. (I.N.)

  4. Concrete peeling off device

    The present invention concerns a device for peeling off activated concretes in processing for discarding a reactor of a nuclear reactor facility. The device comprises a gyrotron for generation microwaves, an irradiator for irradiating output microwaves, a reflection mirror for reflecting and converging the microwaves and irradiating them to a material to be irradiated and a first rotating means for rotating the irradiator and the reflection mirror in parallel with the axis of the gyrotron while maintaining the positional relation between the irradiator and the reflection mirror. When the position of the microwaves irradiated on concrete walls are moved in a circumferential direction and the central axes of the rotational axis and the material to be irradiated are aligned, then the intensity of the irradiation of the microwaves at each of the irradiation points can be maintained constant without changing the focal distance of the reflected microwaves thereby enabling to peel off concretes efficiently. If operation conditions are controlled based on information such as temperature at the periphery of the microwave irradiation positions, the shape and the color of the material to be irradiated and the distance to the material to be irradiated, a concrete peeling off device of high reliability can be obtained. (N.H.)

  5. Rubber glove wearing device

    Rubber groves are attached each to an upper end of a glove putting vessel having an air-sucking hole on the bottom by enlarging an opening end of the rubber glove and turning back the inside to the outside. When the sucking device is operated, air in the glove putting device is sucked and the rubber glove is expanded by an atmospheric pressure. After expansion of the rubber glove to some extent, the sucking device is stopped, and presence or absence of failures of the rubber glove is confirmed by shrinkage of the rubber glove and by an indication value of a pressure gauge for detecting the pressure change in the vessel. Then, a hand is inserted to the expanded rubber glove, and a detaching switch in the vessel is pushed by a finger tip. A detaching piece at the upper end of the vessel is protruded outwardly to enlarge the turned-back portion of the rubber glove to easily release the rubber glove from the putting vessel, and the rubber glove is put on. This enables to wear the rubber glove and conduct failure test simultaneously. Further, a user can put on the rubber glove without touching the outside of the rubber glove. (I.N.)

  6. Electric dialysis device

    The device of the present invention can regenerate liquid salt wastes generated from a nuclear power plant into acid and alkali by electrolysis. Namely, the device has anion exchange membranes disposed in a cell. The inside of the cell is divided into an anode chamber and a cathode chamber. The anode chamber has an anode disposed therein. The cathode chamber has an impurity separating vessel and an cathode disposed therein. Liquid wastes flow into the impurity separating vessel, acid contents flow out of the anode chamber, and alkaline contents flow out of the cathode chamber. The device of the present invention has following advantages. (1) Since impurity separation for the liquid wastes and electric dialysis (acid and alkali separation) can be performed simultaneously, the process is simplified. (2) The amount of wastes generated can be reduced due to precipitation separation by hydrolysis separation of the impurities themselves. (3) Removal of the impurities can be performed only by exchange/disposal of the impurity separating vessel. (4) Since the impurities can be removed by back-wash of recovered acid, no secondary wastes are formed. (I.S.)

  7. Pruning devices in 1995

    This bulletin describes the market situation in April 1995 in Finland concerning devices suitable for silvicultural pruning in forestry. The review is based on the responses to a questionnaire sent to manufacturers and importers. Manually operated pruning devices, relying entirely on muscle power, were manufactured by six companies. There were four models each of branch saws and branch cutters and two models of branch blades. Motorised pruning devices, with the branch-severing power supplied by a combustion engine, battery or a power unit were manufactured by five companies. There were twelve models in all. The amount of pruning done in Finland has diminished year by year from the peak years of 1988-1989 when ca. 13000 hectares were pruned. In 1993 the corresponding figure was 5290 hectares of which 3930 hectares applied to private, non-industrial forestry. One contributing factor to this fall may be seen in the changes that have occurred in forest improvement regulations. The annual target set in the Forest 2000 program is for 20000 hectares to be pruned. (author)

  8. Reactor power measuring device

    The device of the present invention efficiently calibrates a fixed type gamma ray thermometer of a reactor power measuring device of a BWR type reactor. Namely, the device of the present invention calculates peripheral fuel rod power distribution by calibrating the reactor power distribution by heat generation amount, the reactor power distribution being obtained by a calculation based on a reactor model for converting the signals of a plurality of the gamma ray thermometers in the reactor core based on a conversion formula. In this case, the conversion formula is a relational formula between the power of a thermocouple of the gamma ray thermometer, gamma ray heat generation amount, thermocouple zero power sensitivity relative to a temperature coefficient. A conversion efficient calculation means makes a calibration heater to generate heat at a predetermined power, and the thermocouple zero power sensitivity and the temperature coefficient are obtained based on the output of the gamma ray thermometer in this case. The calibration means updates to conversion type thermocouple zero power sensitivity and temperature coefficient. A calibration execution means executes the operations described above successively, and when the thermocouple zero power sensitivity and the temperature coefficient are out of an allowable range, the means informs it and eliminates the corresponding gamma ray thermometer from the measuring meters.

In the first reading in the federal parliament, Federal Minister for the Environment Gabriel emphasized 2 main points: Intensified protection of nuclear facilities and of transports of radioactive substances against unauthorized interventions; transfer by law to the Federal Office for Radiological Protection (BfS) of decommissioning of the Asse mine. Reliability review: The amendment to Sec.12 b of the Atomic Energy Act is to meet the different safety and security conditions after the terrorist attacks on September 11, 2001 in the United States and other terrorist activities afterwards (London, Madrid) also with respect to hazards arising to nuclear facilities and nuclear transports. The bill must be seen in conjunction with the Ordinance on Reliability Reviews under the Atomic Energy Act dated July 1, 1999 which covers reviews of reliability of persons holding special responsibilities. Asse II mine: The competence of the Federal Office for Radiological Protection is achieved by an amendment to Sec.23, Para.1, Number 2, Atomic Energy Act, in which the words ''and for the Asse II mine'' are added after the word ''waste.'' Further proceedings depend on the additional provision in a new Sec.57 b, Atomic Energy Act. Accordingly, the operation and decommissioning of the Asse II mine are subject to the regulations applicable to facilities of the federation pursuant to Sec.9a, Para.3. In this way, Asse II is given the same legal status as the federal waste management facilities. Moreover, it is stipulated that the mine is to be shut down immediately. (orig.)

    Full Text Available In recent times, emerging countries including India have become favored destination for medical device companies to leverage the growth opportunities. However, the Indian regulatory system is not ready to meet the challenges that may come up with growing medical device business. It needs major amendments to current Drugs and Cosmetic Act 1940, to include medical device as a separate entity. Like in developed world, the challenges could be addressed by defining medical devices, risk based classification of devices, guidelines for device safety surveillance, and clinical trials for medical devices. Drugs and Cosmetic (Amendment Bill 2013, which is yet to be released has addressed the concerns to some extent. However, it needs a major revamp to establish effective regulatory framework for medical devices. [Int J Basic Clin Pharmacol 2014; 3(5.000: 764-767

  17. A cyclically actuated electrolytic drug delivery device

    Yi, Ying

    2015-01-01

    This work, focusing on an implantable drug delivery system, presents the first prototype electrolytic pump that combines a catalytic reformer and a cyclically actuated mode. These features improve the release performance and extend the lifetime of the device. Using our platinum (Pt)-coated carbon fiber mesh that acts as a catalytic reforming element, the cyclical mode is improved because the faster recombination rate allows for a shorter cycling time for drug delivery. Another feature of our device is that it uses a solid-drug-in-reservoir (SDR) approach, which allows small amounts of a solid drug to be dissolved in human fluid, forming a reproducible drug solution for long-term therapies. We have conducted proof-of-principle drug delivery studies using such an electrolytic pump and solvent blue 38 as the drug substitute. These tests demonstrate power-controlled and pulsatile release profiles of the chemical substance, as well as the feasibility of this device. A drug delivery rate of 11.44 ± 0.56 μg min-1 was achieved by using an input power of 4 mW for multiple pulses, which indicates the stability of our system. © The Royal Society of Chemistry 2015.

    2012-09-21

    Recent advances in graphene nanoribbon (GNR) electronic devices provide a concrete context for developing simulation methods, comparing theories to experiments, and using simulations to explore device physics. We present a review on modeling of graphene nanoribbon devices, with an emphasis on electronic and magnetoresistive devices. Device modeling is reviewed in a synergistic perspective with GNR material properties, device characteristics, and circuit requirements. Similarity with and difference to carbon nanotube devices are discussed. Device modeling and simulation results are compared to experimental data, which underlines the importance of theory-experiment collaborations in this field. Importance of the GNR edges, which have a negative impact on the carrier mobility due to edge roughness but offer new possibilities of spintronic devices and edge doping, is emphasized. Advanced device modeling of GNRs needs to have the capability to describe GNR device physics, including three-dimensional electrostatics, quantum and atomistic scale effects, elastic and inelastic scattering processes, electron-electron interaction, edge chemistry, magnetic field modulation, and spintronic and thermoelectric device phenomena.

    1993-01-01

    A bus programmable slave module card for use in a computer control system is disclosed which comprises a master computer and one or more slave computer modules interfacing by means of a bus. Each slave module includes its own microprocessor, memory, and control program for acting as a single loop controller. The slave card includes a plurality of memory means (S1, S2...) corresponding to a like plurality of memory devices (C1, C2...) in the master computer, for each slave memory means its own communication lines connectable through the bus with memory communication lines of an associated memory device in the master computer, and a one-way electronic door which is switchable to either a closed condition or a one-way open condition. With the door closed, communication lines between master computer memory (C1, C2...) and slave memory (S1, S2...) are blocked. In the one-way open condition invention, the memory communication lines or each slave memory means (S1, S2...) connect with the memory communication lines of its associated memory device (C1, C2...) in the master computer, and the memory devices (C1, C2...) of the master computer and slave card are electrically parallel such that information seen by the master's memory is also seen by the slave's memory. The slave card is also connectable to a switch for electronically removing the slave microprocessor from the system. With the master computer and the slave card in programming mode relationship, and the slave microprocessor electronically removed from the system, loading a program in the memory devices (C1, C2...) of the master accomplishes a parallel loading into the memory devices (S1, S2...) of the slave.

  20. Heterostructure terahertz devices.

    Ryzhii, Victor

    2008-08-19

    The terahertz (THz) range of frequencies is borderline between microwave electronics and photonics. It corresponds to the frequency bands of molecular and lattice vibrations in gases, fluids, and solids. The importance of the THz range is in part due to numerous potential and emerging applications which include imaging and characterization, detection of hazardous substances, environmental monitoring, radio astronomy, covert inter-satellite communications, as well as biological and medical applications. During the last decades marked progress has been achieved in the development, fabrication, and practical implementation of THz devices and systems. This is primarily owing to the utilization of gaseous and free electron lasers and frequency converters using nonlinear optical phenomena as sources of THz radiation. However, such devices and hence the systems based on them are fairly cumbersome. This continuously stimulates an extensive search for new compact and efficient THz sources based on semiconductor heterostructures. Despite tremendous efforts lasting several decades, the so-called THz gap unbridged by semiconductor heterostructure electron and optoelectron devices still exists providing appropriate levels of power of the generated THz radiation. The invention and realization of quantum cascade lasers made of multiple quantum-well heterostructures already resulted in the partial solution of the problem in question, namely, in the successful coverage of the high-frequency portion of the THz gap (2-3 THz and higher). Further advancement to lower frequencies meets, perhaps, fundamental difficulties. All this necessitates further extensive theoretical and experimental studies of more or less traditional and novel semiconductor heterostructures as a basis for sources of THz radiation. This special issue includes 11 excellent original papers submitted by several research teams representing 14 institutions in Europe, America, and Asia. Several device concepts which

    1998-12-31

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project objective was to evaluate the use of carbon/carbon-fiber-reinforced composites for use in endoprosthetic devices. The application of these materials for the metacarpophalangeal (MP) joints of the hand was investigated. Issues concerning mechanical properties, bone fixation, biocompatibility, and wear are discussed. A system consisting of fiber reinforced materials with a pyrolytic carbon matrix and diamond-like, carbon-coated wear surfaces was developed. Processes were developed for the chemical vapor infiltration (CVI) of pyrolytic carbon into porous fiber preforms with the ability to tailor the outer porosity of the device to provide a surface for bone in-growth. A method for coating diamond-like carbon (DLC) on the articulating surface by plasma-assisted chemical vapor deposition (CVD) was developed. Preliminary results on mechanical properties of the composite system are discussed and initial biocompatibility studies were performed.

  2. Carbon for sensing devices

    Tagliaferro, Alberto

    2015-01-01

    This book reveals why carbon is playing such an increasingly prominent role as a sensing material. The various steps that transform a raw material in a sensing device are thoroughly presented and critically discussed.  The authors deal with all aspects of carbon-based sensors, starting from the various hybridization and allotropes of carbon, with specific focus on micro and nanosized carbons (e.g., carbon nanotubes, graphene) and their growth processes. The discussion then moves to the role of functionalization and the different routes to achieve it. Finally, a number of sensing applications in various fields are presented, highlighting the connection with the basic properties of the various carbon allotropes.  Readers will benefit from this book’s bottom-up approach, which starts from the local bonding in carbon solids and ends with sensing applications, linking the local hybridization of carbon atoms and its modification by functionalization to specific device performance. This book is a must-have in th...

  3. Next generation toroidal devices

    A general survey of the possible approach for the next generation toroidal devices was made. Either surprisingly or obviously (depending on one's view), the technical constraints along with the scientific considerations lead to a fairly limited set of systems for the most favorable approach for the next generation devices. Specifically if the magnetic field strength of 5 T or above is to be created by superconducting coils, it imposes minimum in the aspect ratio for the tokamak which is slightly higher than contemplated now for ITER design. The similar technical constraints make the minimum linear size of a stellarator large. Scientifically, it is indicated that a tokamak of 1.5 times in the linear dimension should be able to produce economically, especially if a hybrid reactor is allowed. For the next stellarator, it is strongly suggested that some kind of helical axis is necessary both for the (almost) absolute confinement of high energy particles and high stability and equilibrium beta limits. The author still favors a heliac most. Although it may not have been clearly stated in the main text, the stability afforded by the shearless layer may be exploited fully in a stellarator. (author)

  4. Control rod blocking device

    Purpose: To increase the degree of freedom for the reactor operation by control rod blocking by monitoring the critical power ratio (CPR) with real time. Constitution: There has been a problem that the withdrawal of control rods may occasionally be inhibited with all the margin in view of CPR. The present invention dissolves this problem. That is, the control rod withdrawal device periodically calculates CPR, and calculated CPR upon generation of a control rod withdrawing signal by conpensating the result of calculation with a LPRM signal and a reactor core flow rate signal. The CPR at real time is compared with a predetermined setting value to output a control rod withdrawing inhibition signal depending on the result of the comparison. In the device as described above, since CPR is monitored at real time, the control rod can be withdrawn without causing fuel damages, as well as the inhibition of withdrawal irrespective of the presence of margin in view of CPR can be avoided. Accordingly, degree of freedom in the reactor operation can be increased. (Kamimura, M.)

  5. Reactor power measuring device

    The present invention provides a self-powered long detector having a sensitivity over the entire length of a reactor core as an entire control rod withdrawal range of a BWR type reactor, and a reactor power measuring device using a gamma ray thermometer which scarcely causes sensitivity degradation. That is, a hollow protection pipe is disposed passing through the reactor core from the outside of a reactor pressure vessel. The self-powered long detectors and the gamma ray thermometers are inserted and installed in the protection pipe. An average reactor power in an axial direction of the reactor relative to a certain position in the horizontal cross section of the reactor core is determined based on the power of the self-powered long detector over the entire length of the reactor core. Since the response of the self-powered detector relative to a local power change is rapid, the output is used as an input signal to a safety protection device of the reactor core. Further, a gamma ray thermometer secured in the reactor and having scarce sensitivity degradation is used instead of an incore travelling neutron monitor used for relative calibration of an existent neutron monitor secured in the reactor. (I.S.)

  6. Power distribution measuring device

    The present invention concerns a device for measuring power distribution of neutrons in a nuclear reactor. That is, a gamma thermometer used so far has drawbacks of slow time response and low sensitivity although it is not always necessary to use a movable incore detector for calibration. However, the device of the present invention compensates the drawback by incorporating a gamma thermometer and an another incore detector of a different type in an identical detector assembly. The gamma thermometer is calibrated by an electric heater. With such a constitution, the sensitivity calibration of the detector of different type incorporated in the identical detector assembly can be conducted without relying on a movable detector when the reactor is stable. Further, if the detector of the different type having rapid response, such as a fission ionization chamber or a self-powered type detector is used as a detector, a reactor core power distribution monitoring system of rapid time response can be attained. (I.S.)

  8. Sport supporting act: terminology issues

    Petr Vlček

    2013-01-01

    Full Text Available BACKGROUND: The text deals with terminology issues from an interdisciplinary point of view. It is based on two different disciplines, law and kinanthropology, in an area of their overlap. AIM: The aim of the author is to point out some possible legislative problems, which could arise due to the current reading of the sport supporting act (Act no. 115/2001. The second aim of the author is to contribute to the discussion of kinantropologists (possibly also the educational researchers and lawyers and to stress the importance of the systematic approach to terminology formulation. METHODS: The author uses the method of language interpretation. We also use the basic analytical methods, induction and deduction, while we stress the systematic approach to the term formulation. RESULTS: The analysis of the sport supporting act terminology shows some specific legislative problems, which could arise due to the definition of sport in the sport supporting act. The author discusses a possible alternative solution. CONCLUSION: According to the opinion of the author, clear, obvious and unified terminology of kinantropologists as specialists in their discipline should represent a source, from which other sciences could derive their terminology. Defined and inexpert terminology used in other disciplines should not be used as an argument for its adopting in kinanthropology.

  10. Against acts of nuclear terrorism

    The Act on the International Convention of the United Nations of April 13, 2005 on Combating Acts of Nuclear Terrorism was promulgated in the German Federal Gazette and entered into force one day later. The Convention expresses the deep concern about the worldwide escalation of all kinds and manifestations of acts of terrorism. What was true in April 2005 (the year the UN convention was adopted) is even more true today. At the same time, however, the Convention recognizes the right of all nations to develop and use nuclear power for peaceful purposes, acknowledging their justified interest in the possible benefits of the peaceful uses of nuclear power. As the Convention was signed in German still during the term of office of the Red-Green government, this passage is a remarkable acceptance of the realities of the world and past peaceful uses of nuclear power in Germany. Whether or not the convention will become an effective instrument to be used against acts of nuclear terrorism and threats depends on its entering into force after deposition of 22 ratification documents, and on as many states as possible acceding to it. Irrespective of these aspects, action in the spirit of the Convention should be taken now, criminal law should be adapted, and international cooperation should be improved and strengthened. (orig.)

  17. Human Factors and Medical Devices

    Medical device hardware- and software-driven user interfaces should be designed to minimize the likelihood of use-related errors and their consequences. The role of design-induced errors in medical device incidents is attracting widespread attention. The U.S. Food and Drug Administration (FDA) is fully cognizant that human factors engineering is critical to the design of safe medical devices, and user interface design is receiving substantial attention by the agency. Companies are paying more attention to the impact of device design, including user instructions, upon the performance of those health professionals and lay users who operate medical devices. Concurrently, the FDA is monitoring human factors issues in its site inspections, premarket device approvals, and postmarket incident evaluations. Overall, the outlook for improved designs and safer device operation is bright

  18. Cybersecurity for Connected Diabetes Devices.

    Klonoff, David C

    2015-09-01

    Diabetes devices are increasingly connected wirelessly to each other and to data-displaying reader devices. Threats to the accurate flow of information and commands may compromise the function of these devices and put their users at risk of health complications. Sound cybersecurity of connected diabetes devices is necessary to maintain confidentiality, integrity, and availability of the data and commands. Diabetes devices can be hacked by unauthorized agents and also by patients themselves to extract data that are not automatically provided by product software. Unauthorized access to connected diabetes devices has been simulated and could happen in reality. A cybersecurity standard designed specifically for connected diabetes devices will improve the safety of these products and increase confidence of users that the products will be secure.

  20. Bistable devices for morphing rotor blades

    Johnson, Terrence

    This dissertation presents two bistable concepts for morphing rotor blades. These concepts are simple and are composed of bistable devices that act as coupling structures between an actuator and the rotor blade. Bistable or "snap-through" mechanisms have two stable equilibrium states and are a novel way to achieve large actuation output stroke at relatively modest effort for gross rotor morphing applications. This is because in addition to the large actuation stroke associated with the snap-through (relative to conventional actuator/ amplification systems) coming at relatively low actuation effort, no locking is required in either equilibrium state (since they are both stable). The first concept that is presented in this dissertation is a that is composed of a bistable twisting device that twists the tip of helicopter rotor blades. This work examines the performance of the presented bistable twisting device for rotor morphing, specifically, blade tip twist under an aerodynamic lift load. The device is analyzed using finite element analysis to predict its load carrying capability and bistable behavior. The second concept that is presented is a concept that is composed of a bistable arch for rotor blade chord extension. The bistable arch is coupled to a thin flat plate that is supported by rollers. Increasing the chord of the rotor blade is expected to generate more lift-load and improve helicopter performance. In this work, a methodology is presented to design the bistable arches for chord morphing using the finite element analysis and pseudo-rigid body model method. This work also examines the effect of different arches, arch hinge size and shape, inertial loads and rigidity on arch performance. Finally, this work shows results from an experiment that was conducted to validate the developed numerical model and demonstrates how the arch can be actuated using a Nitinol Shape Memory Alloy (SMA) wire to extend the chord of a helicopter rotor blade.

  1. Firewood preparation devices in 1994

    A review of the market situation regarding firewood preparation devices is presented. The information was collected from the answers to a mail questionnaire. The review is assumed to include all the leading manufacturers and importers. Firewood production devices were available from 26 manufacturers. The range of models amounted to over 70. These may be divided into three categories: 1. cutting devices: the most common solution being a cross-cutting circular saw. There were only a few of these on sale as it is quite easy to include a splitting device on the same frame. 2. Splitting devices: e.g. screw splitter and hydraulically powered splitter. About 20 models are available on the markets. Cross cutting and splitting devices: these are the most popular devices. A cross-cutting circular saw with screw or hydraulic splitter is the most common type. There are about 50 models available on the markets. Cross-cutting and splitting devices are often equipped with conveyor for transferring the split wood e.g. into a trailer. Chopping devices are delivered as tractor powered devices, as electric motor powered devices or as combustion engine powered devices. Some of them are equipped with a time saving feeding device enabling the next stem to be lifted into position while the previous one is being chopped. The Finnish Work Efficiency Institute's studies show that when cross-cutting and splitting of stems into pieces of 35-50 cm in length, productivity for one operator varies in between 0.8 - 3.2 m3/h, depending on the device and work method used.

  2. Electronic control devices

    The subject of these lectures is the translation of information from particle detectors to computers. Large solid angle general purpose detectors at the intersection regions of high energy e+e- storage rings and pp and pp storage rings are discussed. Three choices for data acquisition are reviewed: use CAMAC (Computer Aided Measurement and Control), start from scratch and design a system, or wait for the final version of the proposed FASTBUS to be developed. The do-it-yourself procedure includes designs of drift chamber discriminator, time to amplitude converter, and data card block diagram. Trigger systems, the fast decision making systems judging an event interesting enough for a read-out cycle to be initiated, are discussed. Finally, a FASTBUS system layout, with its goals of minimum bus speed, general system topologies, and support multiple smart devices is given

  5. Nuclear reactor inspection device

    A typical embodiment of the invention combines a novel cellular end fitting for a nuclear reactor fuel assembly with a new design for a fuel rod end cap and a radiation sensing device probe to provide a means for swiftly and accurately distinguishing sound fuel rods from those rods that have developed leaks. For example, a somewhat thinner than usual fuel rod end cap is accessible through the open cellular structure of the end fitting to permit a hollow metal probe to contact the fuel rod end cap. This direct contact excludes most of the water, metal and other shielding materials from the volume between the interior of the fuel rod and the radiation detector, thereby improving the quality of the fuel rod examination. A bridge and trolley structure for accurately positioning the probe also is described

  6. Nuclear fusion device

    Grooves are formed on the wall surface disposed at the inner side of a vacuum vessel for confining plasmas, to thereby divide the flow channel of induced eddy current. During unsteady state of the plasmas, the flow channel of the eddy current induced on the wall surface is divided into a great number of small loops to inhibit the spacial extension of the induced eddy current, and the value of the induced eddy current is decreased. Therefore, electromagnetic forces formed on the wall surface due to interaction with steady magnetic fields are decreased to reduce the moment of the force exerted on the wall surface. The integrity and the reliability in view of the structure of the thermonuclear device can be improved. (N.H.)

    Wang, Qian; Gholipour, Behrad; Wang, Chih-Ming; Yuan, Guanghui; Teng, Jinghua; Zheludev, Nikolay I

    2015-01-01

    Optoelectronic components with adjustable parameters, from variable-focal-length lenses to spectral filters that can change functionality upon stimulation, have enormous technological importance. Tuning of such components is conventionally achieved by either micro- or nano-mechanical actuation of their consitutive parts, stretching or application of thermal stimuli. Here we report a new dielectric metasurface platform for reconfigurable optical components that are created with light in a non-volatile and reversible fashion. Such components are written, erased and re-written as two-dimensional binary or grey-scale patterns into a nanoscale film of phase change material by inducing a refractive-index-changing phase-transition with tailored trains of femtosecond pulses. We combine germanium-antimony-tellurium-based films optimized for high-optical-contrast ovonic switching with a sub-wavelength-resolution optical writing process to demonstrate technologically relevant devices: visible-range reconfigurable bi-chr...

    Ebe, K.

    1993-10-15

    The wavelength area of the solar cell ranges widely from 0.3[mu]m short wavelength light to 2.4[mu]m long wavelength light, and semiconductor devices are desired to be developed which can absorb those wide range wavelength lights effectively for photoelectrical transfer. This invention is concerned with provision of a wide energy gap superlattice layer, which can absorb short wave light energy of the sunlight, and a narrow energy gap superlattice layer which can absorb long wavelength light energy of the sunlight, by stacking or by interposing the substrate. The energy gap of the formed superlattice layer is varied by gradual or continuous changing of the thickness of the barrier layer and the well layer of the narrow energy gap superlattice layer. As a result, high efficient solar cell is structured which can efficiently absorb the light of the sunlight ranging from short wavelength to long wavelength. 6 figs., 2 tabs.

  16. Reactor core monitoring device

    The device of the present invention reliably and conveniently detects an event of rapid increase of a coolant void coefficient at a portion of a channel by flow channel clogging event in a PWR-type reactor. Namely, upon flow channel clogging event, the coolant void coefficient is increased, an effective density is lowered, and a coolant shielding effect is lowered. Therefore, fast neutron fluxes at the periphery of a pressure tube are increased. The increase of the fast neutron fluxes is detected by a fast neutron flux detector disposed in a guide tube of an existent neutron flux detector. Based on the result, increase of coolant void coefficient can be detected. When an average void coefficient reaches from 30% to 100%, for example, the fast neutron fluxes are increased by about twice at a neutron permeation distance of coolants of about 10cm, thereby enabling to perform effective detection.

    2015-08-01

    Full Text Available Multimedia services over mobile device-to-device (D2D networks has recently received considerable attention. In this scenario, each device is equipped with a cellular communication interface, as well as a D2D interface over a shared medium. In this work, we study the performance properties of the mobile D2D communications in the framework of user satisfaction, and develop a fully distributed QoE-aware multimedia communication scheme (QAMCS. Specifically, we translate the opportunistic multimedia communications issue into a stochastic optimization problem, which opens up a new degree of performance to exploit. Moreover, QAMCS is designed for a heterogeneous and dynamic environment, in which user demand, device mobility, and transmission fashion may vary across different devices and applications. Importantly, QAMCS is able to maximize the user satisfaction and only needs each device to implement its own scheme individually in the absence of a central controller.

  9. From Speech Acts to Semantics

    Mackenzie Jim

    2014-03-01

    Full Text Available Frege introduced the notion of pragmatic force as what distinguishes statements from questions. This distinction was elaborated by Wittgenstein in his later works, and systematised as an account of different kinds of speech acts in formal dialogue theory by Hamblin. It lies at the heart of the inferential semantics more recently developed by Brandom. The present paper attempts to sketch some of the relations between these developments.

  11. Status of long-acting-growth hormone preparations--2015.

    Høybye, Charlotte; Cohen, Pinchas; Hoffman, Andrew R; Ross, Richard; Biller, Beverly M K; Christiansen, Jens Sandahl

    2015-10-01

    Growth hormone (GH) treatment has been an established therapy for GH deficiency (GHD) in children and adults for more than three decades. Numerous studies have shown that GH treatment improves height, body composition, bone density, cardiovascular risk factors, physical fitness and quality of life and that the treatment has few side effects. Initially GH was given as intramuscular injections three times per week, but daily subcutaneous injections were shown to be more effective and less inconvenient and the daily administration has been used since its introduction in the 1980s. However, despite ongoing improvements in injection device design, daily subcutaneous injections remain inconvenient, painful and distressing for many patients, leading to noncompliance, reduced efficacy and increased health care costs. To address these issues a variety of long-acting formulations of GH have been developed.

    Fuel cells were originally intended for use in power plants and vehicles. More recently, developers realised the possibility for building much smaller units and for lower prices per kilowatt than their larger relatives. This has led to a strong interest in developing small fuel cells. Small fuel cells could replace batteries in portable electronic equipment and internal combustion engines in portable generators. The upper limit for portable generators is about 5kW, mainly because of the weight of the fuel cell. The main applications for low-power fuel cells are mobile phones, personal digital assistants, laptop and notebook computers, cameras, medical equipment, military applications and other portable electronic devices. In comparison to batteries, fuel cells can supply much more power per unit volume or weight, though they have lower output voltages and are slower to respond to transients. Fuel cell types that are suitable for portable applications include: proton exchange membrane fuel cells (PEMFCs) using pure hydrogen, PEMFCs using hydrogen-rich gases from hydrocarbon or alcohol reforming, direct methanol fuel cells and, high-temperature fuel cells such as solid oxide fuel cells (SOFCs) and molten carbonate fuel cells (MCFCs) using hydrocarbons directly. Fuel cells for portable devices is becoming a niche, high-value market area which has good opportunities for a fast introduction of fuel cell technology and for the first consumer products in the electronic market can be expected within the coming year and is believed to grow rapidly thereafter. Danish industry is involved in the development of SOFC, PEMFC and DMFC fuel cells and the industry has in particular a strong position in system components and complete systems. An important area for Danish industry is system integration, where fuel cells and hydrogen technologies are implemented in electrical powered products. This is an area that is particular suited for small and medium sized enterprises and for

    Dibos, Alan

    2015-01-01

    The material requirements for optoelectronic devices can vary dramatically depending on the application. Often disparate material systems need to be combined to allow for full device functionality. At the nanometer scale, this can often be challenging because of the inherent chemical and structural incompatibilities of nanofabrication. This dissertation concerns the integration of seemingly dissimilar materials into hybrid optoelectronic devices for photovoltaic, plasmonic, and photonic appli...

  18. Notes on Conformal Invisibility Devices

    Leonhardt, Ulf

    2006-01-01

    As a consequence of the wave nature of light, invisibility devices based on isotropic media cannot be perfect. The principal distortions of invisibility are due to reflections and time delays. Reflections can be made exponentially small for devices that are large in comparison with the wavelength of light. Time delays are unavoidable and will result in wave-front dislocations. This paper considers invisibility devices based on optical conformal mapping. The paper shows that the time delays do...

  20. Barriers to medical device innovation

    Bergsl

    2014-06-01

    Full Text Available Jacob Bergsland, Ole Jakob Elle, Erik Fosse The Intervention Centre, Oslo University Hospital, Institute of Clinical Medicine, University of Oslo, Oslo, Norway Abstract: The US Food and Drug Administration (FDA has defined a medical device as a health care product that does not achieve it's purpose by chemical action or by being metabolized. This means that a vast number of products are considered medical devices. Such devices play an essential role in the practice of medicine. The FDA classifies medical devices in three classes, depending on the risk of the device. Since Class I and II devices have relatively simple requirements for getting to the market, this review will focus on “implantable devices”, which, in general, belong to Class III. The European Union and Canada use a slightly different classification system. While early generations of medical devices were introduced without much testing, either technical or clinical, the process of introducing a Class III medical device from concept to clinical practice has become strongly regulated and requires extensive technological and clinical testing. The modern era of implantable medical devices may be considered to have started in the 1920s with development of artificial hips. The implantable pacemaker was another milestone and pacemakers and cardioverters/defibrillators have since saved millions of lives and created commercial giants in the medical device industry. This review will include some examples of cardiovascular devices. Similar considerations apply to the total implantable device market, although clinical and technological applications obviously vary considerably.

  6. Simulation of semiconductor devices

    Oriato, D

    2001-01-01

    cathode, made using an AIGaAs heterostructure step. Simulations show the importance of the insertion of a thin highly-doped layer between the transit region and the electron launcher in order to improve device operation. Chapter 5 is an introduction to Ill-nitrides, in particular GaN and its alloy ln-GaN. We outline the discrepancy in the elastic and piezoelectric parameters found in the literature. Strain, dislocations and piezoelectricity are presented as the main features of a InGaN/GaN system.

  7. Liquid waste processing device

    In a liquid waste processing device for processing living water wastes discharged from nuclear power plant facilities through a filtration vessel and a sampling vessel, a filtration layer disposed in the filtration vessel is divided into a plurality of layers along planes vertical to the direction of flow and the size of the filter material for each of the divided layers is made finer toward the downstream. Further, the thickness of the filtration material in each of the divided layers is also reduced toward the downstream. The filter material is packed such that the porosity in each of the divided layers is substantially identical. Further, the filtration material is packed in a mesh-like bag partitioned into a desired size and laid with no gaps to the planes vertical to the direction of the flow. Thus, liquid wastes such as living water wastes can be processed easily and simply so as to satisfy circumstantial criteria without giving undesired effects on the separation performance and life time and with easy replacement of filter. (T.M.)

  8. Reactor container spray device

    Purpose: To enable decrease in the heat and the concentration of radioactive iodine released from the reactor vessel into the reactor container in the spray device of BWR type reactors. Constitution: A plurality of water receiving trays are disposed below the spray nozzle in the dry well and communicated to a pressure suppression chamber by way of drain pipeways passing through a diaphragm floor. When the recycling system is ruptured and coolants in the reactor vessel and radioactive iodine in the reactor core are released into the dry well, spray water is discharged from the spray nozzle to eliminate the heat and the radioactive iodine in the dry well. In this case, the receiving trays collect the portions of spray water whose absorption power for the heat and radioactive iodine is nearly saturated and falls them into the pool water of the pressure suppression chamber. Consequently, other portions of the spray water that still possess absorption power can be jetted with no hindrance, to increase the efficiency for the removal of the heat and iodine of the spray droplets. (Horiuchi, T.)

  9. Radioactive iodine removing device

    In a radioactive iodine removing device of an off-gas processing step in a spent fuel reprocessing facility, spiral structures having an inclination of more than about 20deg is disposed at the inside of an iodine adsorbent packing portion, and dampers are disposed at a packing inlet and a discharging exit for iodine adsorbents respectively. After completion of discharge of the iodine adsorbents, a damper disposed in the midway of a adsorbent packing pipeline is opened for packing the iodine absorbents. The iodine adsorbents used have a spherical shape of 10 to 20 mesh (1 to 2mm), and the adsorbents are packed uniformly both radially and vertically to the packing portion upon injection of the adsorbents and, as a result, the packing portion can be made compact. Further, since the discharged iodine adsorbents can be contained in a vessel directly or in a different vessel having an excellent containing performance by taking the dimension of the vessel into consideration, it is possible to reduce the generation amount of wastes than that in a conventional case.

    1991-07-01

    The results of the Conceptual Design Activities for the International Thermonuclear Experimental Reactor (ITER) are summarized. These activities, carried out between April 1988 and December 1990, produced a consistent set of technical characteristics and preliminary plans for co-ordinated research and development support of ITER, a conceptual design, a description of design requirements and a preliminary construction schedule and cost estimate. After a description of the design basis, an overview is given of the tokamak device, its auxiliary systems, facility and maintenance.

  11. Plant monitoring device

    The device of the present invention comprises a data collecting section for periodically collecting processed data sent from plant equipments, a top node induction and processing section for an important plant function model for inducing the plant function to be noted particularly by an operator from important plant function models by using process data and a window screen selection section for selecting a window screen to be displayed based on the result of the evaluation for each of function nodes based on the processing described above and determining the layout and automatically forming the display screen. It is constituted so that the kind and the layout of the window under display are checked if they are the same as those one cycle before or not and, if they are different, the screen is automatically switched to a new screen display. Then, operator's psychological burdens such as selection of information and judgement for the operation upon occurrence of plant abnormality and accident can be mitigated, to provide a safe operation circumstance having reinforced monitoring of the function of the whole plant can be provided. (N.H.)

  12. Radioactive gas solidifying device

    The device of the present invention, a sputtering electrode comprises a cylindrical electrode main body made of a transition metal, electrode caps each made of a transition metal and connected by welding to the upper and the lower portions of the main body and a plurality of annular grooves formed to the outer surface of the electrode main body. The electrode main body and the electrode cap are connected by welding at the portions of the annular grooves, and rare earth elements are filled in the annular grooves. Then, when operation is conducted for a long period of time, the thickness of the electrode is gradually reduced by sputtering. When the rare earth element in the annular grooves are completely eliminated by the reduction of the thickness, radioactive gases are no more injected into the accumulated metal layers of sputtered metal formed at the surface of the ion injection electrode, to reduce the processing efficiency. By detecting the reduction and interrupting the operation directly, the reduction of the wall thickness in the welded portion between the main body and the electrode cap is prevented. In this way, it is possible to prevent the leakage of cooling water therefrom and abnormal electric discharge caused thereby, to enable stable operation for a long period of time. (T.M.)

  13. Ultrasonic wave inspection device

    The device of the present invention inspects incore structural components by visualizing them by scanning an ultrasonic transducer in an opaque liquid metal sodium in a pressure vessel of an FBR type reactor. Namely, a piezoelectric vibrator for transmitting/receiving ultrasonic waves is formed into a protruded shape. A portion at the center of the protruded piezoelectric vibrator is coaxially separated. Upon transmitting ultrasonic waves, a large opening of the entire piezoelectric vibrator is used. A small opening at the center of the piezoelectric vibrator is used upon receiving ultrasonic waves. With such a constitution, an object to be inspected is visualized based on the waveform of the received ultrasonic wave signals defining the center of a curvature of the protruded piezoelectric vibrator as a position of transmitting ultrasonic waves and defining the center of the opening at the center of the piezoelectric vibrator as a position of receiving ultrasonic waves. As a result, the energy of the ultrasonic waves can be enhanced to improve sensitivity upon transmitting ultrasonic waves. Since the distance between an optional position of the receiving surface and the reflecting surface of the object is minimized upon receiving ultrasonic waves, there is no distortion in the waveforms of the received signals thereby enabling to obtain images at high accuracy. (I.S.)

  14. Emergency gas processing device

    The present invention provides an emergency gas processing device which discharged contaminated air in a reactor building to the outside. Namely, a suction port of an emergency gas processing pipeline is disposed in the inside of the reactor building. The exit of the pipeline is connected to an exhaustion pipe of the building. On the side of the inlet of the pipeline, there are disposed an inlet valve, an air dryer, a blower, a filter unit and an exit valve from the suction port to the downstream. A heater is disposed to the air dryer. A recycling pipeline equipped with an automatic closing valve for connecting the inlet side of the inlet valve and the inlet side of the exit valve is disposed. Then, the moisture in an emergency gas flown from the inlet valve is removed, heated by the heater, and the temperature of the emergency gas is elevated. Impurities are removed by the filter unit. The automatic closing valve of the recycling pipeline is opened and the blower and the heater are operated to keep the temperature and humidity in the filter unit to a predetermined value during stand-by time. Upon occurrence of an accident, the automatic closing valve is closed, and the aimed system operation is preformed. (I.S.)

  15. Reactor power measuring device

    The device of the present invention comprises a γ-thermometer disposed in a BWR type reactor, a first amplifier for amplifying the output thereof, a fission ionization chamber disposed in the reactor separately from the γ-thermometer, a second amplifier for amplifying the output thereof, a differential circuit for differentiating the output signal of the second amplifier and a first adding circuit for adding an output signal of the differential circuit and an output signal of the first amplifier. Alternatively, a γ-ray self-powered neutron detector may be disposed instead of the fission ionization chamber. A second adding circuit is also disposed for adding the output signals of plurality of differentiation circuits and inputting the result to the first adding circuit. A sensitivity controller is disposed upstream of the first adder for controlling the sensitivity of the fission ionization chamber. Then, even if time delay should be caused in the γ-thermometer, output signals with good time response characteristic can be obtained by using signals of LPRM or SPND, and currently changing output of the reactor can be measured accurately to provide an effect on the improvement of the safety and operation controllability of the reactor.

  17. Stochastic memristive devices for computing and neuromorphic applications

    Gaba, Siddharth; Sheridan, Patrick; Zhou, Jiantao; Choi, Shinhyun; Lu, Wei

    2013-06-01

    Nanoscale resistive switching devices (memristive devices or memristors) have been studied for a number of applications ranging from non-volatile memory, logic to neuromorphic systems. However a major challenge is to address the potentially large variations in space and time in these nanoscale devices. Here we show that in metal-filament based memristive devices the switching can be fully stochastic. While individual switching events are random, the distribution and probability of switching can be well predicted and controlled. Rather than trying to force high switching probabilities using excess voltage or time, the inherent stochastic nature of resistive switching allows these binary devices to be used as building blocks for novel error-tolerant computing schemes such as stochastic computing and provides the needed ``analog'' feature for neuromorphic applications. To verify such potential, we demonstrated memristor-based stochastic bitstreams in both time and space domains, and show that an array of binary memristors can act as a multi-level ``analog'' device for neuromorphic applications.

    Lim, Chong Wee (Urbana, IL); Shin, Chan Soo (Daejeon, KR); Petrov, Ivan Georgiev (Champaign, IL); Greene, Joseph E. (Champaign, IL)

    2005-01-25

    An Si.sub.x N.sub.y or SiO.sub.x N.sub.y liner is formed on a MOS device. Cobalt is then deposited and reacts to form an epitaxial CoSi.sub.2 layer underneath the liner. The CoSi.sub.2 layer may be formed through a solid phase epitaxy or reactive deposition epitaxy salicide process. In addition to high quality epitaxial CoSi.sub.2 layers, the liner formed during the invention can protect device portions during etching processes used to form device contacts. The liner can act as an etch stop layer to prevent excessive removal of the shallow trench isolation, and protect against excessive loss of the CoSi.sub.2 layer.

    Hauser, L.

    1994-01-01

    Hauser considers John Searle's attempt to distinguish acts from movements. On Searle's account, the difference between me raising my arm and my arm's just going up (e.g., if you forcibly raise it), is the causal involvement of my intention to raise my arm in the former, but not the latter, case. Yet, we distinguish a similar difference between a robot's raising its arm and its robot arm just going up (e.g., if you manually raise it). Either robots are rightly credited with intentions or it's ...

  5. Metal hydride actuation device

    A self-recocking actuation device is disclosed. One possible use for it is in conjunction with a pneumatic fire protection system. This invention employs the process known as occlusion to store large amounts of gas in a small volume. Metal hydrides in a chamber are used to store hydrogen in the disclosed preferred embodiment. Upon the application of heat-from a heat source like a resistance heater-the charged metal hydride releases its hydrogen (H2) in a chamber having only one exit opening which empties into a sealed bellows. This bellows contacts a piston located in another chamber wherein a biased resetting spring is provided to normally maintain the piston in contact with the bellows. As the pressure from the H2 gas builds up, it overcomes the biased spring to move it and the piston along with an associated pin or other actuator. If used to actuate a pneumatic fire protection system, the pin or actuator at the downward side of its stroke in turn, may puncture a shearable diaphragm or in some other way releases the contents of a container containing a second gas, like nitrogen (N2), which is then released from a second exit port in a different chamber to charge the fire protection system. Recocking of the piston begins as the heating of the metal hydride ceases. As cooling takes place the hydrogen is absorbed to reenter the hydride to decrease the gas pressure supplied. The piston's biased resetting spring then recocks the piston to its original position

  7. Polymer Thermoelectric Generators: Device Considerations

    Yee, Shannon

    2014-03-01

    Recent control of the transport properties in polymers has encouraged the development of polymer thermoelectric (TE) devices. Polymer TEs are thought to be less expensive and more scalable than their inorganic counterparts. The cost of the raw material is less and polymer TEs can leverage the large areal manufacturing technique established by the plastics industry. Additionally, while the overall ZT of polymer TEs appears attractive, individual polymer properties have a very different scale than their inorganic counterparts (i.e., the thermal conductivity and electrical conductivity are approximately one and two orders of magnitude smaller, respectively). Furthermore, the majority of TE measurements on polymers have been limited to thin-films where traditional TE materials are measured in bulk. So why should it be expected that polymer TE devices resemble traditional TE devices? Given the uniqueness of polymers, different device architectures are proposed that can leverage the unique strengths of polymer films. It will be shown that by logically considering device requirements, new polymer TE devices have non-linear features that are more attractive than linear inorganic TE devices. This leads to very different device optimizations that favor polymer TEs.

  9. Semiconductor Switching Devices. .Future Trends

    S. Ahmad

    1998-01-01

    Full Text Available A variety of semiconductor devices and circuits have been successfully developed usingconduction properties of electrons and holes in a number of elemental and compound semiconductors.Carriers confinement in a potential well, formed out of a thin layer of lower band gap materialsandwitched between two layers of a higher band gap material, has been extended from one to two andthree dimensions. Resultant of two-dimensional carrier sheet, quantum wire and quantum dot havingdiscrete energy levels arising out of quantisation are being presently explored for possible device applications. A number of devices have been fabricated using resonant tunneling across a thin potentialbarrier. This has opened up several newer possibilities of using such structures for various electronicand optoelectronic devices and circuits applications as tunneling is relatively faster than conductionprocess. While looking into the interband tunneling between two quantum dots, possibility of a singleelectron switching has also been examined carefully. The idea of a single electron switching isconceptually being extended from quantl,lm dots to molecules and atoms ultimately. Simulations basedon transmission of electrons through a chain of molecules and atoms have shown that tens of THz speed and functional device density 1012 devices/mm2 are possible with such schemes. Devices basedon atom relay transistor (ART will be ultimate in its performance of switching speed. A brief onpresent-day situation followed by future proposals of fast switching devices for informationelectronics has been discussed.

    Device characteristics, such as screen size and means of interaction, and the context in which a device is used, seriously affect the user’s mental representation of an information environment and its intended use. We hypothesize that user characteristics are valuable resources for determining which

  16. Electrical nanogap devices for biosensing

    Xing Chen

    2010-11-01

    Full Text Available For detecting substances that are invisible to the human eye or nose, and particularly those biomolecules, the devices must have very small feature sizes, be compact and provide a sufficient level of sensitivity, often to a small number of biomolecules that are just a few nanometres in size. Electrical nanogap devices for biosensing have emerged as a powerful technique for detecting very small quantities of biomolecules. The most charming feature of the devices is to directly transduce events of biomolecules specific binding into useful electrical signals such as resistance/impedance, capacitance/dielectric, or field-effect. Nanogap devices in electrical biosensing have become a busy area of research which is continually expanding. A wealth of research is available discussing planar and vertical nanogap devices for biosensing. Planar nanogap devices including label-free, gold nanoparticle-labeled, nanoparticles-enhanced, nanogapped gold particle film, and carbon nanotube nanogap devices as well as vertical nanogap devices with two and three terminals for biosensing are carefully reviewed. The aim of this paper is to provide an updated overview of the work in this field. In each part, we discuss the principles of operation of electrical biosensing and consider major strategies for enhancing their performance and/or key challenges and opportunities in current stages, and in their further development.

  1. Content Sharing for Mobile Devices

    Ball, Rudi

    2008-01-01

    The miniaturisation of computing devices has seen computing devices become increasingly pervasive in society. With this increased pervasiveness, the technologies of small computing devices have also improved. Mobile devices are now capable of capturing various forms of multimedia and able to communicate wirelessly using increasing numbers of communication techniques. The owners and creators of local content are motivated to share this content in ever increasing volume; the conclusion has been that social networks sites are seeing a revolution in the sharing of information between communities of people. As load on centralised systems increases, we present a novel decentralised peer-to-peer approach dubbed the Market Contact Protocol (MCP) to achieve cost effective, scalable and efficient content sharing using opportunistic networking (pocket switched networking), incentive, context-awareness, social contact and mobile devices. Within the report we describe how the MCP is simulated with a superimposed geographi...

  2. Pressurized waterproof case electronic device

    Berumen, Michael L.

    2013-01-31

    A pressurized waterproof case for an electronic device is particularly adapted for fluid-tight containment and operation of a touch-screen electronic device or the like therein at some appreciable water depth. In one example, the case may be formed as an enclosure having an open top panel or face covered by a flexible, transparent membrane or the like for the operation of the touchscreen device within the case. A pressurizing system is provided for the case to pressurize the case and the electronic device therein to slightly greater than ambient in order to prevent the external water pressure from bearing against the transparent membrane and pressing it against the touch screen, thereby precluding operation of the touch screen device within the case. The pressurizing system may include a small gas cartridge or may be provided from an external source.

  4. Optical device for straightness measurement

    Vekteris, Vladas; Jurevicius, Mindaugas; Turla, Vytautas

    2015-11-01

    The present paper describes the research of the optical device for two-dimensional straightness measurement of technological machines. Mathematical study of an optical device, operating on the phase principle and measuring transversal displacements of machine parts in two directions ( X and Y) during their linear longitudinal motion in a machine (alongside the Z axis), is presented. How to estimate the range of travel along the Z axis is analytically shown. At this range, the measurer gives correct measurements of transverse displacement. The necessary distance from the objective focus to the image plane was defined mathematically. The sample results of measuring the displacement of the table of a technological machine by using the optical device are presented in the paper. This optical device for non-contact straightness measurement can be used for measurement straightness in turning, milling, drilling, grinding machines and other technological machines, also in geodesy and cartography, and for moving accuracy testing of mechatronic devices, robotics and others.

  5. Pyrotechnic devices and their applications

    Himelblau, Harry

    2002-05-01

    Pyroshock is mechanical shock transmitted through structures from explosive devices, sometimes accompanied by structural impact. These devices are designed to cause the intentional separation of structures, or to cause the deployment of various mechanisms or subsystems required for mission operation. Separation devices usually fall into two categories: (a) line sources, such as linear shaped charges, and (b) point sources, such as explosive bolts, pin puller and pushers, and gas generators. The advantages of these devices are high reliability (especially when redundantly activated), low cost and weight, high activation speed, and low structural deformation a short distance from the source. The major limitation is pyroshock, a severe high-frequency transient capable of causing failure or malfunction to small nearby elements, especially electronic and optical components located close to the source. This pyroshock tutorial, which is intended to summarize recent improvements to the technology, is initiated with a review of explosive and companion devices.

  6. Device Applications of Nonlinear Dynamics

    Baglio, Salvatore

    2006-01-01

    This edited book is devoted specifically to the applications of complex nonlinear dynamic phenomena to real systems and device applications. While in the past decades there has been significant progress in the theory of nonlinear phenomena under an assortment of system boundary conditions and preparations, there exist comparatively few devices that actually take this rich behavior into account. "Device Applications of Nonlinear Dynamics" applies and exploits this knowledge to make devices which operate more efficiently and cheaply, while affording the promise of much better performance. Given the current explosion of ideas in areas as diverse as molecular motors, nonlinear filtering theory, noise-enhanced propagation, stochastic resonance and networked systems, the time is right to integrate the progress of complex systems research into real devices.

  7. Pseudo force acting between bodies

    Baruah, Abhinav Ray; Deva, Anish; Sarma, Arun

    It has been shown that a non-contact force acts between two macroscopic physical objects held close together, which is not associated with the gravitational and electrostatic force. An experiment was conducted with objects of different mass, material and geometry to find the magnitude and properties of this apparent or pseudo force. The order of magnitude was found to be 10-5 and it remained constant for all types of objects while only the coefficient increased as the distance between the objects reduced. It only started acting at small distances and failed to make a body move if it experienced static friction from any contact surface. The nature of the force was found to be attractive as well as repulsive. Due to gravitation being a solely attractive force, it was eliminated as a possible reason for the pseudo force. The experiment was performed twice, once by grounding the apparatus and then again without grounding. The order of the force remained the same for both cases. As the test objects were held by hand, they were grounded through the human body. Also, none of the objects used were in contact with each other for the duration of this work, preventing any contact electrification. Due to these factors, the force was not considered electrostatic in nature.

  8. The Problem of Agency; How Humans Act, How Machines Act

    Rose, Jeremy; Jones, M.; Truex, D.

    2003-01-01

    A long-standing debate in the IS literature concerns the relationship between technology and organization. Is it technology that acts on organizations, or humans that determine how technology is used? Proposals for a middle way between the extremes of technological and social determinism have been...... put forward based on Giddens’ structuration theory, and, more recently, from actor network theory. The two theories, however, may be seen to adopt rather different, and potentially incompatible, views of agency (action). Thus, structuration theory sees agency as a uniquely human property, whereas the...... it the mangers and unions (the human agents) that were determining the trajectory of the organization, or did the ERP system also play a role? This paper argues that neither structuration theory or actor network theory offers a particularly convincing account of the interplay of human and machine...

  10. Intrauterine Contraceptive Device Migrated into the Urinary Bladder and a Review of the Literature

    Orhan Zorba

    2013-08-01

    Full Text Available Intrauterine contraceptive devices are being used in clinical practice since 1962. Due to their efficiency and low cost, intrauterine contraceptive devices are the most popular method of reversible contraception in developing countries. The incidence of migration of an intrauterine contraceptive device, and related uterine perforation ranges from 0.003% to 0.87%. Intrauterine contraceptive device may migrate into urinary bladder, appendix, rectum, colon, peritoneum, anterior abdominal wall or ovary. Foreign bodies like sutures, stents, and needles in the urinary bladder act as niduses for calculi formation. Intrauterine contraceptive device migrated into the bladder can also become a nidus for a stone formation.Herein we report about a case whose intrauterine contraceptive devices had migrated into the bladder, and presented with lower urinary tract symptoms and suprapubic discomfort 6 years after its insertion.

  18. Multilayer polymer light emitting devices

    Barcikowski, Zachary; Thomas, Adam; Tzolov, Marian

    2013-03-01

    The interplay of device layers and their interfaces is a major area of study in Polymer Light Emitting Devices (PLEDs). Many factors such as the degradation, efficiency, and overall performance depend on how these layers interact with each other. A fundamental understanding of the interfaces of these layers can lend to better performing devices using a multitude of organic polymers deposited in conjunction with each other in several ways. We have studied basic PLED devices in which we vary the emissive layer used, along with final bake temperatures. Devices include a glass substrate with Indium Tin Oxide anode, Aluminum cathode, and Plexcore Hole Injection layer. The active polymer films were spin casted from solution of MEH-PPV and PFO. Single layer and dual layers of several polymers are studied by examining current-voltage characteristics, film densities, impedance measurements, light emission, and efficiency calculations. We have found that not only do dual layers positively alter the performance of the device in the majority of cases, but the solvents in which each layer is originally in when deposited affects the formation of the interface, thereby altering the device mechanisms.

  19. High voltage MOSFET devices and methods of making the devices

    Banerjee, Sujit; Matocha, Kevin; Chatty, Kiran

    2015-12-15

    A SiC MOSFET device having low specific on resistance is described. The device has N+, P-well and JFET regions extended in one direction (Y-direction) and P+ and source contacts extended in an orthogonal direction (X-direction). The polysilicon gate of the device covers the JFET region and is terminated over the P-well region to minimize electric field at the polysilicon gate edge. In use, current flows vertically from the drain contact at the bottom of the structure into the JFET region and then laterally in the X direction through the accumulation region and through the MOSFET channels into the adjacent N+ region. The current flowing out of the channel then flows along the N+ region in the Y-direction and is collected by the source contacts and the final metal. Methods of making the device are also described.

  2. Learning activism, acting with phronesis

    Lee, Yew-Jin

    2015-12-01

    The article "Socio-political development of private school children mobilising for disadvantaged others" by Darren Hoeg, Natalie Lemelin, and Lawrence Bencze described a language-learning curriculum that drew on elements of Socioscientific issues and Science, Technology, Society and Environment. Results showed that with a number of enabling factors acting in concert, learning about and engagement in practical action for social justice and equity are possible. An alternative but highly compatible framework is now introduced—phronetic social research—as an action-oriented, wisdom-seeking research stance for the social sciences. By so doing, it is hoped that forms of phronetic social research can gain wider currency among those that promote activism as one of many valued outcomes of an education in science.

  4. Acting Antarctica: science on stage

    Ciceri, Piera; Tizzoni, Paola; Pierro, Luigia

    2016-04-01

    Key-words: Polar science, Earth science, Theatre, Hands on activities The legendary Antarctic Expedition of sir E. Shackleton and his crew of 27 aboard the Endurance (1914/16) trapped in the Antarctic ice has become the starting point to learn about Polar Science and Climate Change. While the students were involved into this incredible adventure by the astonishing images of the Australian photographer Frank Hurley (who joined the crew), they discovered the world in which this story happened. Students were then involved in hands-on activities and role plays and have become the writers of the play "Uomini a scienza ai confini del mondo". They act the story of Shackelton's expedition and they tell at the same time to the audience about ice pack, ice cores and their role in understanding the past of the climate, physical and geographical characteristic of polar regions, thermal phenomena related to adaptations of polar animals, solar radiation at different latitude, day/night duration. The theater was the place to "stage" some scientific experiments and to explain the current research carried out in polar regions and their importance in climate change studies and to stress some similarities between Antarctica and space. The project was carried out from teachers of science, letters and geography and was born in collaboration with the "Piccolo Teatro di Milano" and the association "Science Under 18" with the support of a professional actor and director and was played for other schools at "EXPO 2015" in Milano (Italy). In our opinion drama activities improve reading comprehension, and both verbal and non-verbal communication skills. To be able to write and to act, students need a deep understanding of contents. Arts, including theatre, are a good key to involve emotionally students. To have an audience different from their own teachers and classmates offers a real task and the opportunity to play and let grow real skills.

  5. Skin-inspired electronic devices

    Alex Chortos

    2014-09-01

    Full Text Available Electronic devices that mimic the properties of skin have potential important applications in advanced robotics, prosthetics, and health monitoring technologies. Methods for measuring tactile and temperature signals have progressed rapidly due to innovations in materials and processing methods. Imparting skin-like stretchability to electronic devices can be accomplished by patterning traditional electronic materials or developing new materials that are intrinsically stretchable. The incorporation of sensing methods with transistors facilitates large-area sensor arrays. While sensor arrays have surpassed the properties of human skin in terms of sensitivity, time response, and device density, many opportunities remain for future development.

  6. Arrhythmia management after device removal.

    Nishii, Nobuhiro

    2016-08-01

    Arrhythmic management is needed after removal of cardiac implantable electronic devices (CIEDs). Patients completely dependent on CIEDs need temporary device back-up until new CIEDs are implanted. Various methods are available for device back-up, and the appropriate management varies among patients. The duration from CIED removal to implantation of a new CIED also differs among patients. Temporary pacing is needed for patients with bradycardia, a wearable cardioverter defibrillator (WCD) or catheter ablation is needed for patients with tachyarrhythmia, and sequential pacing is needed for patients dependent on cardiac resynchronization therapy. The present review focuses on arrhythmic management after CIED removal. PMID:27588151

  11. Review of the nuclear liability act

    There has always been concern that nuclear materials have the potential to cause injury and property damage. For this reason, nuclear operators have always been required by national regulatory authorities to exercise special precautions in the operation of their facilities. Federal legislation was drafted in Canada as the Nuclear Liability Act in 1970. The Act ensures that funds are available from all operators of nuclear facilities to provide financial compensation to third parties for injuries or damages suffered as a result of a nuclear incident; at the same time the Act provides protection to the operators by limiting their related liability. The Act also protects persons other than operators. The review of the Act has progressed in stages. The first stage was conducted by the staff of the Atomic Energy Control Board and catalogued previously identified difficulties with the Act. The second stage was a preliminary examination of the Act by an Interdepartmental Working Group. 2 figs

The displacer occupies the lower section of the core and divides the column of liquid in two parts consisting of the control column above the displacer and protective column below the drain throttle. The proposed device provides the control of energy distribution along the core height and can be used for leveling energy distribution field or its shaping. A reliable operation of the device is insured, in particular, the stability of such important characteristics as the position and height of the column of liquid, the magnitude of introduced reactivity, the range of controlled parameters

The devices are based on the use of guided acoustic waves to modulate the light in...... channel waveguides and Mach-Zehnder interferometers. Numerical models are developed based on the finite element method, and applied to several scenarios, such as optimization of the geometrical parameters of waveguides, use of slow light in photonic crystal waveguides and use of Lamb waves in membranized...... were investigated. Comparisons are made with the numerical and experimental results, and they validate the obtained response of the acoustic and photonic components of the device. Finally, a new design for an optical frequency shifter is proposed, posing several advantages over existing devices in...

  4. Three-terminal superconducting devices

    The transistor has a number of properties that make it so useful. The authors discuss these and the additional properties a transistor would need to have for high performance applications at temperatures where superconductivity could contribute advantages to system-level performance. These properties then serve as criteria by which to evaluate three-terminal devices that have been proposed for applications at superconducting temperatures. FETs can retain their transistor properties at low temperatures, but their power consumption is too large for high-speed, high-density cryogenic applications. They discuss in detail why demonstrated superconducting devices with three terminals -Josephson effect based devices, injection controlled weak links, and stacked tunnel junction devices such as the superconducting transistor proposed by K. Gray and the quiteron -- each fail to have true transistor-like properties. They conclude that the potentially very rewarding search for a transistor compatible with superconductivity in high performance applications must be in new directions

    Pluta, M.; Milewska, D.; Mazikowski, A.

    2015-09-01

    An optoelectronic system for measurements of hematocrit level (HCT) in the whole human blood is presented. Proposed system integrates a dedicated optoelectronic sensor, a microcontroller and a small LCD display in a low cost, battery-powered, handheld device. Chosen method for determining blood hematocrit level is based on optical properties of whole blood in visible and NIR wavelength range. Measurements with the use of proposed system require blood samples (small drop in the range of microliters) which is placed in the micro cuvette. Then, absorption of the sample is measured at wavelengths of 570 nm and 880 nm. Prototype of the device was build and tested. Test results confirmed proper operation of the device with correct metrological parameters in application to HCT level measurements. Such a portable device can be used as a tool of bedside diagnosis, which becomes interesting alternative to full laboratory tests.

  20. Dental devices; reclassification of root-form endosseous dental implants and endosseous dental implant abutments. Final rule.

    2004-05-12

    The Food and Drug Administration (FDA) is reclassifying root-form endosseous dental implants and endosseous dental implant abutments from class III to class II (special controls). Root-form endosseous dental implants are intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore the patient's chewing function. Endosseous dental implant abutments are separate components that are attached to the dental implant and intended to aid in prosthetic rehabilitation. FDA is reclassifying these devices on its own initiative on the basis of new information. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document that will serve as the special control for these devices. FDA is taking this action under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Medical Device Amendments of 1976 (the 1976 amendments), the Safe Medical Devices Act of 1990, the Food and Drug Administration Modernization Act of 1997, and the Medical Device User Fee and Modernization Act of 2002.

    Frazier, Donald O.; Singer, Christopher E.; Rogers, Jan R.; Schramm, Harry F.; Fabisinski, Leo L.; Lowenthal, Mark; Ray, William J.; Fuller, Kirk A.

    2010-01-01

    The energy-efficient, environmentally friendly technology that will be presented is the result of a Space Act Agreement between NthDegree Technologies Worldwide, Inc., and the National Aeronautics and Space Administration's (NASA's) Marshall Space Flight Center (MSFC). The work combines semiconductor and printing technologies to advance lightweight electronic and photonic devices having excellent potential for commercial and exploration applications. Device development involves three projects that relate to energy generation and consumption: (1) a low-mass efficient (low power, low heat emission) micro light-emitting diode (LED) area lighting device; (2) a low-mass omni-directional efficient photovoltaic (PV) device with significantly improved energy capture; and (3) a new approach to building super-capacitors. These three technologies, energy capture, storage, and usage (e.g., lighting), represent a systematic approach for building efficient local micro-grids that are commercially feasible; furthermore, these same technologies, appropriately replacing lighting with lightweight power generation, will be useful for enabling inner planetary missions using smaller launch vehicles and to facilitate surface operations during lunar and planetary surface missions. The PV device model is a two sphere, light trapped sheet approximately 2-mm thick. The model suggests a significant improvement over current thin film systems. For lighting applications, all three technology components are printable in-line by printing sequential layers on a standard screen or flexographic direct impact press using the three-dimensional printing technique (3DFM) patented by NthDegree. One primary contribution to this work in the near term by the MSFC is to test the robustness of prototype devices in the harsh environments that prevail in space and on the lunar surface. It is anticipated that this composite device, of which the lighting component has passed off-gassing testing, will function

    Full Text Available Teaching language for specific purposes is the basis of the MGIMO Bachelors’ and Masters’ language education. However, it is experts on language and teaching rather than specialists in the sphere of law that are engaged in this work. The author of this article shares her experience of mastering a new specialization and applying her linguistic knowledge to it.It is creating educational resources that requires not only careful selection of authentic texts, defining specialized lexical base, but also viewing these texts as a complex syntactic whole, possessing its own structure and constituting a language unit that can be modeled. Linguistic perception of specialized texts facilitates the creation of practice-oriented educational resources, the application of which results in university graduates’ ability to use the language of their profession properly.The main conclusion from the results presented in this research shows that the dependent clauses act as the limiting ones. This allows you to add unambiguity and clarity to professional language. Simultaneous accesses to the world of reality and the world of language explains its primary role in verbal and cogitative human activity and puts the sentence as the basic unit of speech in the center of the "language - thinking" system, relating thought and language structures in the overall implementation of the communicative function of language.DOI: http://dx.doi.org/10.12731/2218-7405-2013-6-6

  12. Wireless Inductive Power Device Suppresses Blade Vibrations

    Morrison, Carlos R.; Provenza, Andrew J.; Choi, Benjamin B.; Bakhle, Milind A.; Min, James B.; Stefko, George L.; Duffy, Kirsten P.; Fougers, Alan J.

    Vibration in turbomachinery can cause blade failures and leads to the use of heavier, thicker blades that result in lower aerodynamic efficiency and increased noise. Metal and/or composite fatigue in the blades of jet engines has resulted in blade destruction and loss of lives. Techniques for suppressing low-frequency blade vibration, such as gtuned circuit resistive dissipation of vibratory energy, h or simply "passive damping," can require electronics incorporating coils of unwieldy dimensions and adding unwanted weight to the rotor. Other approaches, using vibration-dampening devices or damping material, could add undesirable weight to the blades or hub, making them less efficient. A wireless inductive power device (WIPD) was designed, fabricated, and developed for use in the NASA Glenn's "Dynamic Spin Rig" (DSR) facility. The DSR is used to simulate the functionality of turbomachinery. The relatively small and lightweight device [10 lb (approx.=4.5 kg)] replaces the existing venerable and bulky slip-ring. The goal is the eventual integration of this technology into actual turbomachinery such as jet engines or electric power generators, wherein the device will facilitate the suppression of potentially destructive vibrations in fan blades. This technology obviates slip rings, which require cooling and can prove unreliable or be problematic over time. The WIPD consists of two parts: a remote element, which is positioned on the rotor and provides up to 100 W of electrical power to thin, lightweight piezoelectric patches strategically placed on/in fan blades; and a stationary base unit that wirelessly communicates with the remote unit. The base unit supplies inductive power, and also acts as an input and output corridor for wireless measurement, and active control command to the remote unit. Efficient engine operation necessitates minimal disturbance to the gas flow across the turbine blades in any effort to moderate blade vibration. This innovation makes it

    2014-01-01

    Device-to-device communication is currently a hot research topic within 3GPP. Even though D2D communication has been part of previous ad hoc, meshed and sensor networks proposals, the main contribution by 3GPP is that the direct communication among two devices is carried out over a dynamically...... assigned, licensed spectrum; thus, it is under full control of the cellular network. D2D communication creates a market potential for new services, new approaches to efficient spectrum use, and security concepts. This is especially true if D2D communication is extended to larger communication groups...... organized in meshed clusters. In this article, we discuss the potential and shortcomings of D2D communication as proposed today, advocating for the use of network coding as an enabling technology for enhanced security and communication efficiency using the PlayNCool and CORE protocols as key examples to...

  15. Contamination detection device for radioactive material transporting device

    The present invention provides a device for detecting leakage of radioactive materials and clogging of a vial in a radioactive material transporting device. Namely, a transporting tube pneumatically transports the vial containing a sample of radioactive materials. A fine flow tube is laid in adjacent with and along the transporting tube. A pump flows a detection liquid prepared by a preparation device to the fine flow tube. A flow-cell type spectrophotometer is disposed to the fine flow tube. The detection liquid is preferably containing elements having a valency changeable by undergoing radiation irradiation, which is a type used, for example, for a Fricke dosimeter. With such a constitution, the position of the radioactive contamination of the inside of the pneumatic tube and clogging of a vial can be detected only by flowing radiation sensitive detection liquid to the fine flow tube. In addition, the detection liquid is not activated only changing the valency of the contained elements. (N.H.)

  16. MANAGING, SEARCHING, AND ACCESSING IOT DEVICES VIA REST RESOURCES

    Jarogniew Rykowski

    2015-09-01

    Full Text Available n this paper a new method is proposed for management of REST-based services acting as proxies for Internet-of-Things devices. The method is based on a novel way of monitoring REST resources by hierarchical set of directories, with the possibility of smart searching for “the best” device according to atthe-place devices’ availability and functionality, overall context (including geo-location, and personal preferences. The system is resistant to changes of network addresses of the devices and their services, as well as core system points such as directories. Thus, we successfully deal with the problem of (disconnectivity and mobility of network nodes, and the problem of a “newcomer” device trying to connect to the network at an incidental place/time. Main novelty of the approach is a summary of three basic achievements. Firstly, the system introduces unifying tools for efficient monitoring. On one hand, we may control an availability and load (statistics of devices/services. On the other hand, we are able to search for “the best” device/service with different criteria, also formulated ad-hoc and personalized. Secondly, the system is resistant to sudden changes of network topology and connections (basically IP addressing, and frequent disconnections of any system element, including core nodes such as central directories. As a result, we may have a common view to the whole system at any time/place and with respect to its current state, even if the elements of the system are distributed across a wider area. Thirdly, any element of the system, from simple devices to global directories, is able to self-adjust to evolving parameters of the environment (including other devices as a part of this environment. In particular, it is possible for a mobile “newcomer” device to interact with the system at any place and time without a need for prior installation, re-programming, determination of actual parameters, etc. The presented approach is

    Song, Lingyang; Xu, Chen

    2013-01-01

    Device-to-Device (D2D) communication will become a key feature supported by next generation cellular networks, a topic of enormous importance to modern communication. Currently, D2D serves as an underlay to the cellular network as a means to increase spectral efficiency. Although D2D communication brings large benefits in terms of system capacity, it also causes interference as well as increased computation complexity to cellular networks as a result of spectrum sharing. Thus, efficient resource management must be performed to guarantee a target performance level of cellular communication.This

  18. An Overview of Biofield Devices.

    Muehsam, David; Chevalier, Gaétan; Barsotti, Tiffany; Gurfein, Blake T

    2015-11-01

    Advances in biophysics, biology, functional genomics, neuroscience, psychology, psychoneuroimmunology, and other fields suggest the existence of a subtle system of "biofield" interactions that organize biological processes from the subatomic, atomic, molecular, cellular, and organismic to the interpersonal and cosmic levels. Biofield interactions may bring about regulation of biochemical, cellular, and neurological processes through means related to electromagnetism, quantum fields, and perhaps other means of modulating biological activity and information flow. The biofield paradigm, in contrast to a reductionist, chemistry-centered viewpoint, emphasizes the informational content of biological processes; biofield interactions are thought to operate in part via low-energy or "subtle" processes such as weak, nonthermal electromagnetic fields (EMFs) or processes potentially related to consciousness and nonlocality. Biofield interactions may also operate through or be reflected in more well-understood informational processes found in electroencephalographic (EEG) and electrocardiographic (ECG) data. Recent advances have led to the development of a wide variety of therapeutic and diagnostic biofield devices, defined as physical instruments best understood from the viewpoint of a biofield paradigm. Here, we provide a broad overview of biofield devices, with emphasis on those devices for which solid, peer-reviewed evidence exists. A subset of these devices, such as those based upon EEG- and ECG-based heart rate variability, function via mechanisms that are well understood and are widely employed in clinical settings. Other device modalities, such a gas discharge visualization and biophoton emission, appear to operate through incompletely understood mechanisms and have unclear clinical significance. Device modes of operation include EMF-light, EMF-heat, EMF-nonthermal, electrical current, vibration and sound, physical and mechanical, intentionality and nonlocality, gas and

  19. Survey of cryogenic semiconductor devices

    Talarico, L.J.; McKeever, J.W.

    1996-04-01

    Improved reliability and electronic performance can be achieved in a system operated at cryogenic temperatures because of the reduction in mechanical insult and in disruptive effects of thermal energy on electronic devices. Continuing discoveries of new superconductors with ever increasing values of T{sub c} above that of liquid nitrogen temperature (LNT) have provided incentive for developing semiconductor electronic systems that may also operate in the superconductor`s liquid nitrogen bath. Because of the interest in high-temperature superconductor (HTS) devices, liquid nitrogen is the cryogen of choice and LNT is the temperature on which this review is focused. The purpose of this survey is to locate and assemble published information comparing the room temperature (298 K), performance of commercially available conventional and hybrid semiconductor device with their performance at LNT (77K), to help establish their candidacy as cryogenic electronic devices specifically for use at LNT. The approach to gathering information for this survey included the following activities. Periodicals and proceedings were searched for information on the behavior of semiconductor devices at LNT. Telephone calls were made to representatives of semiconductor industries, to semiconductor subcontractors, to university faculty members prominent for their research in the area of cryogenic semiconductors, and to representatives of the National Aeronautics and Space Administration (NASA) and NASA subcontractors. The sources and contacts are listed with their responses in the introduction, and a list of references appears at the end of the survey.

  20. Radioactive gaseous waste processing device

    In a radioactive gaseous waste processing device, a dehumidifier in which a lot of hollow thread membranes are bundled and assembled is disposed instead of a dehumidifying cooling device and a dehumidifying tower. The dehumidifier comprises a main body, a great number of hollow thread membranes incorporated in the main body, a pair of fixing members for bundling and fixing both ends of the hollow thread membranes, a pair of caps for allowing the fixing members to pass through and fixing them on both ends of the main body, an off gas flowing pipe connected to one of the caps, a gas exhaustion pipe connected to the other end of the cap and a moisture removing pipeline connected to the main body. A flowrate control valve is connected to the moisture removing pipeline, and the other end of the moisture removing pipeline is connected between a main condensator and an air extraction device. Then, cooling and freezing devices using freon are no more necessary, and since the device uses the vacuum of the main condensator as a driving source and does not use dynamic equipments, labors for the maintenance is greatly reduced to improve economical property. The facilities are reduced in the size thereby enabling to use space effectively. (N.H.)
