    SciTech Connect

    Zhuang, Kun Da; Tan, Seck Guan; Tay, Kiang Hiong

    2012-08-15

    The 'SAFARI' technique or subintimal arterial flossing with antegrade-retrograde intervention is a method for recanalisation of chronic total occlusions (CTOs) when subintimal angioplasty fails. Retrograde access is usually obtained via the popliteal, distal anterior tibial artery (ATA)/dorsalis pedis (DP), or distal posterior tibial artery (PTA). Distal access via the peroneal artery has not been described and has a risk of continued bleeding, leading to compartment syndrome due to its deep location. We describe our experience in two patients with retrograde access via the peroneal artery and the use of balloon-assisted hemostasis for these retrograde punctures. This approach may potentially give more options for endovascular interventions in lower limb CTOs.

  6. Burdick's Technique for Biliary Access Revisited.

    PubMed

    Goenka, Mahesh Kumar; Rai, Vijay Kumar

    2015-01-01

    The precut sphincterotomy is used to facilitate selective biliary access in cases of difficult biliary cannulation. Needle-knife precut papillotomy is the standard of care but is associated with a high rate of complications such as pancreatitis, duodenal perforation, bleeding, etc. Sometimes during bowing of the sphincterotome/cannula and the use of guide wire to facilitate biliary cannulation, inadvertent formation of a false passage occurs in the 10 to 11 o'clock direction. Use of this step to access the bile duct by the intramucosal incision technique was first described by Burdick et al., and since then two more studies have also substantiated the safety and efficacy of this non-needle type of precut sphincterotomy. In this review, we discuss this non-needle technique of precut sphincterotomy and also share our experience using this "Burdick's technique." PMID:25674522

    2015-06-01

    Endovascular repair has replaced open surgical repair as the standard of care for treatment of abdominal and thoracic aortic aneurysms in appropriately selected patients owing to its decreased morbidity and length of stay and excellent clinical outcomes. Similarly, there is a progressive trend toward total percutaneous repair of the femoral artery using percutaneous suture-mediated closure devices over open surgical repair due to decreased complications and procedure time. This article describes the techniques of closure for large-bore vascular access most commonly used in endovascular treatment of abdominal and thoracic aortic aneurysms, but could similarly be applied to any procedure requiring large-bore arterial access, such as transcatheter aortic valve replacement.

  8. Laser Scar Management Technique

    PubMed Central

    Ohshiro, Toshio; Sasaki, Katsumi

    2013-01-01

    Background and Aims: Scars are common and cause functional problems and psychological morbidity. Recent advances in optical technologies have produced various laser systems capable of revising the appearance of scars from various etiologies to optimize their appearance. Methods: Laser treatment can commence as early as the time of the initial injury and as late as several years after the injury. Several optical technologies are currently available and combined laser/light treatments are required for treatment of scars. Since 2006, we have set up a scar management department in our clinic and more than 2000 patients have been treated by our combined laser irradiation techniques. Herein, we review several available light technologies for treatment of surgical, traumatic, and inflammatory scars, and discuss our combined laser treatment of scars, based upon our clinical experience. Results and Conclusions: Because scars have a variety of potential aetiologies and take a number of forms, no single approach can consistenty provide good scar treatment and management. The combination of laser and devices is essential, the choice of wavelength and approach being dictated by each patient as an individual. PMID:24511202

  11. “Wire-Target” Technique for Precise Vascular Access

    PubMed Central

    Hamzeh, Rabih K.; Danon, Saar; Shah, Sanjay; Levi, Daniel S.; Moore, John W.

    2009-01-01

    Herein, we describe a technique that facilitates percutaneous vascular access when the traditional method of achieving access is unsuccessful. For multiple reasons, gaining access to small vessels in pediatric patients is sometimes difficult. In instances of atrial, ventricular, or great arterial communications, a wire can be positioned from a vein or artery across the communications into an artery or vein to which access needs to be gained. This wire then serves as a target for vascular access. All pediatric patients who underwent cardiac catheterization at Mattel Children's Hospital from July 2003 through June 2006, and at Rady Children's Hospital from July through December 2006, were considered for the wire-target technique when access could not be achieved in vessels of interest via traditional methods. Fifteen wire-target procedures were undertaken in 14 patients (ages, 4 d–11 yr). By use of a directional catheter, a Wholey or 0.014-inch coronary wire was positioned in a vessel to which access was desired. Anterior–posterior and lateral fluoroscopic views were used to target the wire and attain vascular access. The patients' diagnoses, ages, vessels to which access was gained via traditional methods and via the wire-target technique, and wire routes were retrospectively recorded, and outcomes were noted. In all instances, the technique was performed successfully and without complications. In selected pediatric patients in whom percutaneous vascular access is difficult, the wire-target technique may be used safely and effectively to establish arterial, venous, or transhepatic access.

  13. Access Control Management for SCADA Systems

    NASA Astrophysics Data System (ADS)

    Hong, Seng-Phil; Ahn, Gail-Joon; Xu, Wenjuan

    The information technology revolution has transformed all aspects of our society including critical infrastructures and led a significant shift from their old and disparate business models based on proprietary and legacy environments to more open and consolidated ones. Supervisory Control and Data Acquisition (SCADA) systems have been widely used not only for industrial processes but also for some experimental facilities. Due to the nature of open environments, managing SCADA systems should meet various security requirements since system administrators need to deal with a large number of entities and functions involved in critical infrastructures. In this paper, we identify necessary access control requirements in SCADA systems and articulate access control policies for the simulated SCADA systems. We also attempt to analyze and realize those requirements and policies in the context of role-based access control that is suitable for simplifying administrative tasks in large scale enterprises.

  14. Satellite data management for effective data access

    NASA Technical Reports Server (NTRS)

    Hogan, Patrick D.; Kotlarek, Thomas L.

    1987-01-01

    The management of data generated from satellite missions has not always led to effective access of that data by the scientific community. NASA has tried to alleviate this problem for ocean scientists, by initiating a program, the NASA Ocean Data System (NODS). The menu-based user interface that NODS employs allows a user to make request and receive answers within a short time of accessing the system. A catalog system, which holds information about oceanographic data sets may be queried to determine the suitability of a particular data set. Once a candidate data set is found, the user is directed to the person or place which actually holds the data. NODS also has an archive system that holds data from ocean-observing satellites. The archive may be queried to obtain a manageable data subset that can be delivered in a useful form.

    2005-01-01

    One key issue in the Black Mesa – Black Canyon area is the interaction between motorized vehicles and. The working hypothesis for this study is that early season elk movement onto private lands and the National Park is precipitated by increased use of Off Highway Vehicles (OHV’s). Data on intensity of motorized use is extremely limited. In this study, we monitor intensity of motorized vehicle and trail use on elk movements and habitat usage and analyze interactions. If management agencies decide to alter accessibility, we will monitor wildlife responses to changes in the human-use regime. This provides a unique opportunity for adaptive management experimentation based on coordinated research and monitoring. The products from this project will provide natural resource managers across the nation with tools and information to better meet these resource challenges.

  7. Increasing access and support for emergency management higher education programs.

    PubMed

    Cwiak, Carol L

    2014-01-01

    The number of emergency management higher education programs has grown dramatically since 1994 when the FEMA Higher Education Program was created to propagate and support such growth. Data collected annually since 2007 from emergency management higher education programs shows that these programs face some consistent challenges. These challenges were coupled with annual data on program access and support indicators via dimensional analysis to answer the questions: To what extent are the challenges linked to a lack of access or support? If there is linkage, what can be gleaned from these linkages that can help address the challenges through improving access and support? The analysis showed that lack of access to funding and resources, and lack of support from partner organizations, has an impact on emergency management higher education. Discussion of that impact is followed with detailed recommendations that are focused on strengthening both internal and external access and support relationships for emergency management higher education programs.

    This document addresses techniques to access and integrate data for defining site-specific conditions and behaviors associated with ground-water and surface-water radionuclide transport applicable to U.S. Nuclear Regulatory Commission reviews. Environmental models typically require input data from multiple internal and external sources that may include, but are not limited to, stream and rainfall gage data, meteorological data, hydrogeological data, habitat data, and biological data. These data may be retrieved from a variety of organizations (e.g., federal, state, and regional) and source types (e.g., HTTP, FTP, and databases). Available data sources relevant to hydrologic analyses for reactor licensing are identified and reviewed. The data sources described can be useful to define model inputs and parameters, including site features (e.g., watershed boundaries, stream locations, reservoirs, site topography), site properties (e.g., surface conditions, subsurface hydraulic properties, water quality), and site boundary conditions, input forcings, and extreme events (e.g., stream discharge, lake levels, precipitation, recharge, flood and drought characteristics). Available software tools for accessing established databases, retrieving the data, and integrating it with models were identified and reviewed. The emphasis in this review was on existing software products with minimal required modifications to enable their use with the FRAMES modeling framework. The ability of four of these tools to access and retrieve the identified data sources was reviewed. These four software tools were the Hydrologic Data Acquisition and Processing System (HDAPS), Integrated Water Resources Modeling System (IWRMS) External Data Harvester, Data for Environmental Modeling Environmental Data Download Tool (D4EM EDDT), and the FRAMES Internet Database Tools. The IWRMS External Data Harvester and the D4EM EDDT were identified as the most promising tools based on their ability to access and

  10. Percutaneous Endovascular Salvage Techniques for Implanted Venous Access Device Dysfunction

    SciTech Connect

    Breault, Stéphane; Glauser, Frédéric; Babaker, Malik Doenz, Francesco Qanadli, Salah Dine

    2015-06-15

    PurposeImplanted venous access devices (IVADs) are often used in patients who require long-term intravenous drug administration. The most common causes of device dysfunction include occlusion by fibrin sheath and/or catheter adherence to the vessel wall. We present percutaneous endovascular salvage techniques to restore function in occluded catheters. The aim of this study was to evaluate the feasibility, safety, and efficacy of these techniques.Methods and MaterialsThrough a femoral or brachial venous access, a snare is used to remove fibrin sheath around the IVAD catheter tip. If device dysfunction is caused by catheter adherences to the vessel wall, a new “mechanical adhesiolysis” maneuver was performed. IVAD salvage procedures performed between 2005 and 2013 were analyzed. Data included clinical background, catheter tip position, success rate, recurrence, and rate of complication.ResultsEighty-eight salvage procedures were performed in 80 patients, mostly women (52.5 %), with a mean age of 54 years. Only a minority (17.5 %) of evaluated catheters were located at an optimal position (i.e., cavoatrial junction ±1 cm). Mechanical adhesiolysis or other additional maneuvers were used in 21 cases (24 %). Overall technical success rate was 93.2 %. Malposition and/or vessel wall adherences were the main cause of technical failure. No complications were noted.ConclusionThese IVAD salvage techniques are safe and efficient. When a catheter is adherent to the vessel wall, mechanical adhesiolysis maneuvers allow catheter mobilization and a greater success rate with no additional risk. In patients who still require long-term use of their IVAD, these procedures can be performed safely to avoid catheter replacement.

  12. Optical multiple access techniques for on-board routing

    NASA Technical Reports Server (NTRS)

    Mendez, Antonio J.; Park, Eugene; Gagliardi, Robert M.

    1992-01-01

    The purpose of this research contract was to design and analyze an optical multiple access system, based on Code Division Multiple Access (CDMA) techniques, for on board routing applications on a future communication satellite. The optical multiple access system was to effect the functions of a circuit switch under the control of an autonomous network controller and to serve eight (8) concurrent users at a point to point (port to port) data rate of 180 Mb/s. (At the start of this program, the bit error rate requirement (BER) was undefined, so it was treated as a design variable during the contract effort.) CDMA was selected over other multiple access techniques because it lends itself to bursty, asynchronous, concurrent communication and potentially can be implemented with off the shelf, reliable optical transceivers compatible with long term unattended operations. Temporal, temporal/spatial hybrids and single pulse per row (SPR, sometimes termed 'sonar matrices') matrix types of CDMA designs were considered. The design, analysis, and trade offs required by the statement of work selected a temporal/spatial CDMA scheme which has SPR properties as the preferred solution. This selected design can be implemented for feasibility demonstration with off the shelf components (which are identified in the bill of materials of the contract Final Report). The photonic network architecture of the selected design is based on M(8,4,4) matrix codes. The network requires eight multimode laser transmitters with laser pulses of 0.93 ns operating at 180 Mb/s and 9-13 dBm peak power, and 8 PIN diode receivers with sensitivity of -27 dBm for the 0.93 ns pulses. The wavelength is not critical, but 830 nm technology readily meets the requirements. The passive optical components of the photonic network are all multimode and off the shelf. Bit error rate (BER) computations, based on both electronic noise and intercode crosstalk, predict a raw BER of (10 exp -3) when all eight users are

  13. Image guided portal vein access techniques in TIPS creation and considerations regarding their use

    PubMed Central

    2016-01-01

    Transjugular intrahepatic portosystemic shunt (TIPS) is a difficult procedure to perform and accessing the portal vein is a very challenging step. There are three broad categories of image guided TIPS creation techniques. Each technique has its advantages and disadvantages. TIPS procedure carries some risk of complications regardless of the guidance technique employed. The technology for TIPS has evolved in parallel with the expanding indications for TIPS. Ultrasound guidance technique offers a safe option, particularly for patients with challenging anatomy. Patient safety should always come first and the US guided technique should be more routinely used. Experience is the main factor in the success of TIPS. Other factors to consider in reducing the all-cause morbidity and mortality are patient selection, patient management and the clinical setting. PMID:27385392

    1994-08-01

    During chemical weapons challenge inspections, the CWC treaty allows ``alternate means`` of access to be proposed by the nation challenged. BNL`s Safeguards, Safety and Nonproliferation Division is funded by the Defense Nuclear Agency to develop a system to provide the challenge inspection team with a ``virtual presence`` within the facility while denying personal access. A general purpose configuration of a mobile station manned by site personnel and a base station manned by the challenge inspector, supported by a flexible communication system, will allow facility personnel to tailor the basic model to their site. Design of the MACS system is based on maximum use of commercial equipment that is available on the international market. Design requirements for the MACS system include methods of establishing geographical position, distance measuring equipment for use in verifying dimensions on floor plans, video and two-way audio links between the mobile unit and the base station, and portability and versatility of the equipment. The MACS platform will also support deployment of selected instrumentation which the site may offer to the challenge inspection team. This paper describes the design and construction of the prototype MACS system.

  17. Safety management of Ethernet broadband access based on VLAN aggregation

    NASA Astrophysics Data System (ADS)

    Wang, Li

    2004-04-01

    With broadband access network development, the Ethernet technology is more and more applied access network now. It is different from the private network -LAN. The differences lie in four points: customer management, safety management, service management and count-fee management. This paper mainly discusses the safety management related questions. Safety management means that the access network must secure the customer data safety, isolate the broad message which brings the customer private information, such as ARP, DHCP, and protect key equipment from attack. Virtue LAN (VLAN) technology can restrict network broadcast flow. We can config each customer port with a VLAN, so each customer is isolated with others. The IP address bound with VLAN ID can be routed rightly. But this technology brings another question: IP address shortage. VLAN aggregation technology can solve this problem well. Such a mechanism provides several advantages over traditional IPv4 addressing architectures employed in large switched LANs today. With VLAN aggregation technology, we introduce the notion of sub-VLANs and super-VLANs, a much more optimal approach to IP addressing can be realized. This paper will expatiate the VLAN aggregation model and its implementation in Ethernet access network. It is obvious that the customers in different sub-VLANs can not communication to each other because the ARP packet is isolated. Proxy ARP can enable the communication among them. This paper will also expatiate the proxy ARP model and its implementation in Ethernet access network.

  18. Techniques in distal access of wide-necked giant intracranial aneurysms during treatment with flow diversion

    Kan, Peter; Wakhloo, Ajay Kumar; Mokin, Maxim; Puri, Ajit

    2015-01-01

    Background: Accessing the normal distal vessel in treatment of wide-necked giant intracranial aneurysms with flow diversion can be difficult. Case Description: Through illustrative cases, the authors present several useful techniques in distal access of wide-necked giant aneurysms during flow diversion treatment. Obtaining an optimal projection that separates the outflow limb from the aneurysm is most critical. Each of the three techniques described enabled the distal access to giant intracranial aneurysms during treatment with flow diversion. Conclusion: The looped-around technique, balloon-assisted technique, and retrograde access are valuable strategies in crossing the aneurysm if direct distal access cannot be obtained. PMID:26069851

    NASA Astrophysics Data System (ADS)

    Al-Alawi, Raida

    2010-06-01

    The ever increasing number of vehicles in most metropolitan cities around the world and the limitation in altering the transportation infrastructure, led to serious traffic congestion and an increase in the travelling time. In this work we exploit the emergence of novel technologies such as the internet, to design an intelligent Traffic Management System (TMS) that can remotely monitor and control a network of traffic light controllers located at different sites. The system is based on utilizing Embedded Web Servers (EWS) technology to design a web-based TMS. The EWS located at each intersection uses IP technology for communicating remotely with a Central Traffic Management Unit (CTMU) located at the traffic department authority. Friendly GUI software installed at the CTMU will be able to monitor the sequence of operation of the traffic lights and the presence of traffic at each intersection as well as remotely controlling the operation of the signals. The system has been validated by constructing a prototype that resembles the real application.

    PubMed

    Londoño, Juan Carlos; Singh, Vikas; Martinez, Claudia A

    2012-06-01

    Percutaneous intervention of chronic limb ischemia is often limited by vascular access especially in patients with previous surgical interventions. This warrants development of alternative endovascular techniques, particularly for patients in whom traditional ipsilateral antegrade or contralateral retrograde access has failed or is not possible. We describe a novel approach to the posterior tibial artery using retrograde access with transradial techniques including closure devices in two patients with inaccessible antegrade access.

  1. Discretionary access control in a heterogeneous distributed data base management system

    SciTech Connect

    Wang, C.Y.

    1986-01-01

    An important technical problem in building a distributed database management system (DDBMS) is access control which prevents unauthorized access or malicious destruction of a database. Consider a DDBMS that uses a uniform global data model to integrate the local schemes of existing DBMSs at the sites of a network. The local DBMSs are unchanged, and the DDBMS is implemented as a module on top of the existing DBMSs at each site. The DBMS at each site is expected to retain its autonomy. That is, the local DBMS at each site maintains control of the data stored at that site. Each local DBMS decides for itself if a user (of the local DBMS or of the DDBMS) may access the data it manages. The design of the access control system for the database in such an environment presents several problems. First, the DBMSs at different sites may have different and incompatible access control mechanisms. Second, queries involving data from multiple sites must be processed by the access control mechanisms of multiple and possible different local DBMSs. Coordinating the access control mechanisms of these DBMSs to provide a consistent access control facility to the users of the heterogeneous DDBMS is a difficult task. This research discusses the problem described above. A general architecture for a DDBMS was developed. Data abstraction techniques were adapted to specify the architecture. A formal verification for the specification was completed.

    Guidelines and clinical practice recommendations vary on the management of vascular access ports. Traditionally, patient, health system and healthcare professional's factors have been interrelated in studies of clinical practice variability. Understanding variation in the management of vascular access ports and to identify the influence of these factors in the compliance with the most common recommendations of vascular access guidelines, is an important first step for designing targeted improvement interventions. We analysed data from a survey sent to all Spanish outpatient clinics. Overall, 185 units at Spanish outpatients clinics out of a total of 256 completed the survey. Geographical region and unit size are the most common associated factors in the management of vascular access ports and there is a low level of compliance with many of the recommendations given by guidelines. Large outpatient chemotherapy units have been related to higher monitoring of the recommendations. Clinical practice and provided care to patients with vascular access ports are influenced by region and structural and organisational differences in the outpatient chemotherapy units. It is important to identify additional factors that may explain the variability. PMID:26075498

  8. Accuracy of dilution techniques for access flow measurement during hemodialysis.

    PubMed

    Krivitski, N M; MacGibbon, D; Gleed, R D; Dobson, A

    1998-03-01

    Access flow is now widely measured by creating artificial recirculation with the dialysis lines reversed and using dilution methods that sense either ultrasound velocity, electrical impedance, optical, or thermal changes. This study identifies and quantifies factors that influence the accuracy of access flow measurements and recommends ways to reduce these errors. Two major sources of access flow measurement error are identified, arising firstly from the second pass of the indicator by recirculation through the cardiopulmonary system (cardiopulmonary recirculation, CPR), and secondly from changes in venous line blood flow (Qb) and vascular access flow induced by the pressure of venous bolus injections. These errors are considered from theory, by direct measurement of access flow in a sheep model, and by analysis of clinical data. Two extremes for the venous introduction of indicator can be considered in access flow measurements, a slow infusion, which perturbs neither the venous line flow nor access flow but increases the error attributable to the second pass of the indicator by recirculation through cardiopulmonary system, or rapid injection, which eases separation of the second pass of the indicator signal but generates changes in the venous flow and access flow. If CPR is not eliminated, the area added to that of the first pass of indicator ranges up to 40%. Good time resolution could permit the separation of the areas generated by the first and second passage of the indicator. In sheep experiments, injections of 5 or 10 mL into a venous port close to the vascular access caused Qb to change by 20% to 40%. Both the animal experiments and analysis of raw data collected during routine clinical dialysis showed that moving the injection site sufficiently far from the patient, before or into the venous bubble trap, reduced the increase in Qb to only approximately 5% during the critical time when the concentration curve is changing for most tubing brands (Baxter, Belco

  9. Opportunities for Process Monitoring Techniques at Delayed Access Facilities

    2013-09-20

    Except for specific cases where the International Atomic Energy Agency (IAEA) maintains a continuous presence at a facility (such as the Japanese Rokkasho Reprocessing Plant), there is always a period of time or delay between the moment a State is notified or aware of an upcoming inspection, and the time the inspector actually enters the material balance area or facility. Termed by the authors as “delayed access,” this period of time between inspection notice and inspector entrance to a facility poses a concern. Delayed access also has the potential to reduce the effectiveness of measures applied as part of the Safeguards Approach for a facility (such as short-notice inspections). This report investigates the feasibility of using process monitoring to address safeguards challenges posed by delayed access at a subset of facility types.

    2013-08-01

    Universal access to health services is a challenge for municipal administration in a society that treats health as a commodity and gives preference to the individual consumer to the detriment of the citizen. This study sought to identify the social representations in the narrative of local health managers in a micro-region of southeast Brazil about access to health services. It consists of qualitative research with interviews conducted with 16 managers. The Collective Subject Discourse technique was employed with the use of Qualiquantisoft software in the data analysis. Four core ideas were identified: coordination between federal states; reorganization of admission procedures; user service and the precariousness of guaranteed access. It was revealed that the quality, resolvability, approach to the user's needs and the care network organization are poorly addressed, which reflects an understanding that does not consider 'access quality and resolution.' It is understood that the managers' impotence to make changes and the lack of society and worker engagement in management bolster the supremacy of market interests and contribute to 'limited access' and the continuity of the hegemonic model of care.

    1978-01-01

    The XIO system is a set of subroutines that provide generalized data management capability for FORTRAN programs using a direct access file. Arrays of integer, real, double precision, and character data may be stored, each logical group of data identified by a unique matrix number. A matrix may be organized and stored as batches to reduce core requirements. Batches may be accessed randomly or sequentially. The file may be checkpointed and retained, allowing for restarts with stored values. The XIO subroutines operate on either IBM 360-370/OS/VS or DEC PDP-11/RSX computing systems.

    1989-01-01

    The use of Code Division Multiple Access (CDMA) to satisfy the diverse requirements of a generic (land, maritime, aeronautical) mobile satellite system (MSS) network design is discussed. Comparisons between CDMA and Frequency Division Multiple Access (FDMA) show that a CDMA network design can support significantly more voice channel allocations than FDMA when relatively simple CDMA correlation receivers are employed, provided that there is sufficient space segment equivalent isotropically radiated power (EIRP). The use of more advanced CDMA receivers can improve the spectral and power efficiency. Although the use of CDMA may not gain immediate and widespread support in the international MSS community, provision for the use of CDMA for a domestic system in the U.S., and possibly for a regional system throughout North America, is likely.

  15. Improving access to adequate pain management in Taiwan.

    PubMed

    Scholten, Willem

    2015-06-01

    There is a global crisis in access to pain management in the world. WHO estimates that 4.65 billion people live in countries where medical opioid consumption is near to zero. For 2010, WHO considered a per capita consumption of 216.7 mg morphine equivalents adequate, while Taiwan had a per capita consumption of 0.05 mg morphine equivalents in 2007. In Asia, the use of opioids is sensitive because of the Opium Wars in the 19th century and for this reason, the focus of controlled substances policies has been on the prevention of diversion and dependence. However, an optimal public health outcome requires that also the beneficial aspects of these substances are acknowledged. Therefore, WHO recommends a policy based on the Principle of Balance: ensuring access for medical and scientific purposes while preventing diversion, harmful use and dependence. Furthermore, international law requires that countries ensure access to opioid analgesics for medical and scientific purposes. There is evidence that opioid analgesics for chronic pain are not associated with a major risk for developing dependence. Barriers for access can be classified in the categories of overly restrictive laws and regulations; insufficient medical training on pain management and problems related to assessment of medical needs; attitudes like an excessive fear for dependence or diversion; and economic and logistical problems. The GOPI project found many examples of such barriers in Asia. Access to opioid medicines in Taiwan can be improved by analysing the national situation and drafting a plan. The WHO policy guidelines Ensuring Balance in National Policies on Controlled Substances can be helpful for achieving this purpose, as well as international guidelines for pain treatment.

    Laryngomalacia is the most common cause of newborn stridor. Management can usually be accomplished without surgery. When surgery is necessary, the carbon dioxide (CO2) laser plays an essential role in enabling precise, hemostatic dissection. The authors present their application of the CO2 laser with microspot control for laser correction of laryngomalacia, with emphasis upon the use of the Boston University suspension system to achieve external suspension of the larynx and the bivalved laryngoscope to achieve tissue distension. Review of indications, technique and results is shared to detail the utility of the CO2 laser in supraglottoplasty.

  17. Access to care - an unmet need in headache management?

    PubMed Central

    2014-01-01

    Access to care for headache sufferers is not always simple. A survey conducted in a large number of members of lay associations point to the existence of multiple barriers to care for headache in several European countries. Patients usually discover the existence of specialized structures with a delay of several years after the onset of their headache. Furthermore, a relevant portion of them are not satisfied with the management of their disease, partly because of the poor efficacy of treatments and partly because of the difficulty to get in touch with the specialist. Headache disorders, and primary headaches in particular, represent an important issue in public health, because they are common, disabling and treatable. A joint effort is required from the relevant stakeholders (scientists, lay organizations, decision-makers, healthcare policymakers, and others) to improve the access to care for headache sufferers.

    Lockheed Martin's Intelligent Library System (ILS)TM imagery management solution was originally developed for users and distributors of Earth imagery emanating from commercial remote sensing satellites or aircraft. The product is a total hardware and software solution comprised of two main components: SmartArchiverTM digital asset management system and SmartAnalystTM imagery exploration tools. While investigating the latest technologies and developing Intelligent Library System (ILS)TM as a state-of-the-art system, we realized SmartArchiver systems offered robust functionality not available elsewhere for handling large medical imagery files. The SmartArchiver system's features answer the following needs of medical imagery handling: smooth handling of large individual imagery files; easy access to specific imagery or types of imagery; cost-effective storage of historical data and protection of imagery over time; ability to grow an archive to thousands of terabytes; distribution from a central archive to multiple viewing sites; varying levels of resolutions requirements at the viewing stations; strict multi-level security adherence; and automated workflow management. In this paper we detail the features of the system and how they apply to medical imagery management. We also describe how a medical application can be served by the SmartArchiver asset management system.

    Permanent transvenous cardiac pacing is usually accomplished through the upper limb veins. When these are occluded, several other vascular access options exist which include the internal jugular, external jugular, femoral and iliac veins as well as more proximal access of the subclavian veins. Anterograde and retrograde techniques to restore subclavian venous patency has been described. A review of these approaches is undertaken, with a discussion of their pros and cons. Familiarity with these techniques will enable the implanter to perform transvenous pacing when faced with limited vascular access. PMID:27326197

    2013-09-01

    Virtualization is a new technology that creates virtual environments based on the existing physical resources. This article evaluates effect of virtualization techniques on control servers and access method in storage systems [1, 2]. In control server virtualization, we have presented a tile based evaluation based on heterogeneous workloads to compare several key parameters and demonstrate effectiveness of virtualization techniques. Moreover, we have evaluated the virtualized model using VMotion techniques and maximum consolidation. In access method, we have prepared three different scenarios using direct, semi-virtual, and virtual attachment models. We have evaluated the proposed models with several workloads including OLTP database, data streaming, file server, web server, etc. Results of evaluation for different criteria confirm that server virtualization technique has high throughput and CPU usage as well as good performance with noticeable agility. Also virtual technique is a successful alternative for accessing to the storage systems especially in large capacity systems. This technique can therefore be an effective solution for expansion of storage area and reduction of access time. Results of different evaluation and measurements demonstrate that the virtualization in control server and full virtual access provide better performance and more agility as well as more utilization in the systems and improve business continuity plan.

  2. Strategies for managing aortoiliac occlusions: access, treatment and outcomes

    PubMed Central

    Clair, Daniel G; Beach, Jocelyn M

    2015-01-01

    Treatment of severe aortoiliac disease has dramatically evolved from a dependence on open aortobifemoral grafting to hybrid and endovascular only approaches. Open surgery has been the gold standard treatment of severe aortoiliac disease with excellent patency rates, but with increased length of stay and major complications. In contrast, endovascular interventions can successfully treat almost any lesion with decreased risk, compared to open surgery. Although primary patency rates remain inferior, secondary endovascular interventions are often minor procedures resulting in comparable long-term outcomes. The risks of renal insufficiency, embolization and access complications are not insignificant; however, most can be prevented or managed without significant clinical consequence. Endovascular therapies should be considered a first-line treatment option for all patients with aortoiliac disease, especially those with high-risk cardiovascular comorbidities. PMID:25907618

    2006-01-01

    This paper discusses human spaceflight fault management operations. Fault detection and response capabilities available in current US human spaceflight programs Space Shuttle and International Space Station are described while emphasizing system design impacts on operational techniques and constraints. Preflight and inflight processes along with products used to anticipate, mitigate and respond to failures are introduced. Examples of operational products used to support failure responses are presented. Possible improvements in the state of the art, as well as prioritization and success criteria for their implementation are proposed. This paper describes how the architecture of a command and control system impacts operations in areas such as the required fault response times, automated vs. manual fault responses, use of workarounds, etc. The architecture includes the use of redundancy at the system and software function level, software capabilities, use of intelligent or autonomous systems, number and severity of software defects, etc. This in turn drives which Caution and Warning (C&W) events should be annunciated, C&W event classification, operator display designs, crew training, flight control team training, and procedure development. Other factors impacting operations are the complexity of a system, skills needed to understand and operate a system, and the use of commonality vs. optimized solutions for software and responses. Fault detection, annunciation, safing responses, and recovery capabilities are explored using real examples to uncover underlying philosophies and constraints. These factors directly impact operations in that the crew and flight control team need to understand what happened, why it happened, what the system is doing, and what, if any, corrective actions they need to perform. If a fault results in multiple C&W events, or if several faults occur simultaneously, the root cause(s) of the fault(s), as well as their vehicle-wide impacts, must be

    Percutaneous endoscopic gastrostomy (PEG) is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition. Besides its well-known advantages over parenteral nutrition, PEG offers superior access to the gastrointestinal system over surgical methods. Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide, knowing its indications and contraindications is of paramount importance in current medicine. PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish. Broadly, the two main indications of PEG tube placement are enteral feeding and stomach decompression. On the other hand, distal enteral obstruction, severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients. Although generally considered to be a safe procedure, there is the potential for both minor and major complications. Awareness of these potential complications, as well as understanding routine aftercare of the catheter, can improve the quality of care for patients with a PEG tube. These complications can generally be classified into three major categories: endoscopic technical difficulties, PEG procedure-related complications and late complications associated with PEG tube use and wound care. In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance. Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the "pull" technique being the most common method. In the last section of this review, the reader is presented with a brief discussion of these procedures, techniques and related issues

    Future high quality communication services will be offered in an integrated or converged network infrastructure maintaining both fixed wireless and mobile access via multi-mode user terminals. A support of various scenarios of user and/or terminal mobility within a common IP-based infrastructure requires intelligently designed control protocols. A major challenge is to provide seamless (i.e. lossless and low delay) handover between different radio cells and operator domains to enable continuation of unicast and multicast sessions while using network resources most efficiently. IETF (Internet Engineering Task Force) is specifying related IP mobility management protocols to be applicable also to a flat architecture as envisaged by Next Generation (Mobile) Networks (NGNs/NGMNs). The contribution will describe operator requirements towards such an approach. Both single-domain and multi-domain scenarios will be discussed based on federation ideas. Already existing solutions are taken into consideration and application of solution proposals towards a Distributed Mobility Management (DMM) currently under evaluation within IETF will be outlined.

    2008-04-01

    An RFID-based mobile handheld inventory management system is proposed in this paper. Differing from the manual inventory management method, the proposed system works on the personal digital assistant (PDA) with an RFID reader. The system identifies electronic tags on the properties and checks the property information in the back-end database server through a ubiquitous wireless network. The system also provides a set of functions to manage the back-end inventory database and assigns different levels of access privilege according to various user categories. In the back-end database server, to prevent improper or illegal accesses, the server not only stores the inventory database and user privilege information, but also keeps track of the user activities in the server including the login and logout time and location, the records of database accessing, and every modification of the tables. Some experimental results are presented to verify the applicability of the integrated RFID-based mobile handheld inventory management system.

    1992-06-01

    The vast number of available healthcare services can be confusing to those seeking care. Care managers can resolve these issues by helping the vulnerable and their families find and receive appropriate services. Care management is not limited to the elderly: Others with special needs also benefit from care management. Care managers integrate and coordinate services, providing a continuum between the client and the providers of acute, long-term, home-based, and community-based care. The care management model that most organizations adopt at first is the brokering model. In this model care managers identify the appropriate service package from resources in the community. In the service management model, the care manager authorizes the services provided within specified financial limits. The funding source influences what services he or she can recommend. Another model is managed care. The carrier of a high-risk group of clients or a group of enrollees in a certain healthcare program prospectively pays the organization providing care management. In the acute care setting, providers find the transition to care management challenging because they have been oriented to short, episodic care. These providers must adopt new protocols to be able to work with providers and programs within their own organization or at other organizations. In community-based care, care managers' goal is to help the client and family access appropriate services so the client can function independently within his or her home. Community-based referrals are from family members or agencies and infrequently follow an acute care hospitalization. PMID:10118342

    This report is an introduction to decision analysis and problem-solving techniques for professionals in natural resource management. Although these managers are often called upon to make complex decisions, their training in the natural sciences seldom provides exposure to the decision-making tools developed in management science. Our purpose is to being to fill this gap. We present a general analysis of the pitfalls of group problem solving, and suggestions for improved interactions followed by the specific techniques. Selected techniques are illustrated. The material is easy to understand and apply without previous training or excessive study and is applicable to natural resource management issues.

    NASA's Operation IceBridge (OIB) mission, initiated in 2009, collects airborne remote sensing measurements over the polar regions to bridge the gap between NASA's Ice, Cloud and Land Elevation satellite (ICESat) mission and the upcoming ICESat-2 mission in 2016. OIB combines an evolving mix of instruments to gather data on topography, ice and snow thickness, high-resolution photography, and other properties that are more difficult or impossible to measure via satellite. Once collected, these data are stored and made available at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. To date, there are nearly 90 terabytes of data available, and there are about three more years of data collection left. The main challenges faced in data management at NSIDC are derived from the quantity and heterogeneity of the data. To deal with the quantity of data, the technical teams at NSIDC have significantly automated the data ingest, metadata generation, and other required data management steps. Heterogeneity of data and the evolution of the Operation over time make technical automation complex. To limit complexity, the IceBridge team has agreed to such practices as using specific data file formats, limiting file sizes, using specific filename templates, etc. These agreements evolve as Operation IceBridge moves forward. The metadata generated about the flights and the data collected thereon make the storage of the data more robust, and enable data discoverability. With so much metadata, users can search the vast collection with ease using specific parameters about the data they seek. An example of this in action is the IceBridge data portal developed at NSIDC, http://nsidc.org/icebridge/portal/. This portal uses the GPS data from the flights projected onto maps as well as other flight and instrument metadata to help the user find the exact data file they seek. This implementation is only possible with dependable data management beneath the surface. The data files

    Management of hidradenitis suppurativa (HS) of the axilla which is nonresponding to conservative management presents a significant therapeutic challenge. Most surgical treatment options are associated with significant morbidities and prolonged hospital stay. We present a technique of management of HS using setons which is simple and allows the ongoing treatment to be done on an outpatient basis. Given the fact that HS is a chronic relapsing condition each recurrence may again be managed using this technique. This will allow the patients to manage their recurrences with minimal impact on their activities of daily living. PMID:26301111

    The management and control of a representative, highly integrated high-technology project, in the X-29A aircraft flight test project is addressed. The X-29A research aircraft required the development and integration of eight distinct technologies in one aircraft. The project management system developed for the X-29A flight test program focuses on the dynamic interactions and the the intercommunication among components of the system. The insights gained from the new conceptual framework permitted subordination of departments to more functional units of decisionmaking, information processing, and communication networks. These processes were used to develop a project management system for the X-29A around the information flows that minimized the effects inherent in sampled-data systems and exploited the closed-loop multivariable nature of highly integrated projects.

    Large scale space programs analyze thousands of requirements while mitigating safety, performance, schedule, and cost risks. These efforts involve a variety of roles with interdependent use cases and goals. For example, study managers and facilitators identify ground-rules and assumptions for a collection of studies required for a program or project milestone. Task leaders derive product requirements from the ground rules and assumptions and describe activities to produce needed analytical products. Disciplined specialists produce the specified products and load results into a file management system. Organizational and project managers provide the personnel and funds to conduct the tasks. Each role has responsibilities to establish information linkages and provide status reports to management. Projects conduct design and analysis cycles to refine designs to meet the requirements and implement risk mitigation plans. At the program level, integrated design and analysis cycles studies are conducted to eliminate every 'to-be-determined' and develop plans to mitigate every risk. At the agency level, strategic studies analyze different approaches to exploration architectures and campaigns. This paper describes a web-accessible database developed by NASA to coordinate and manage tasks at three organizational levels. Other topics in this paper cover integration technologies and techniques for process modeling and enterprise architectures.

  2. Efficient Service Delivery for High-speed Railway Communications Using MIMO and Access Control Technique

    2014-07-01

    In order to realize the notion of "anytime, anywhere" communication for high-speed train passengers, the Long Term Evolution for Railway is designed to provide broadband accesses and reliable communications for high-speed train passengers. However, with the increase of train speed, the system is subject to high bit error rate, Doppler frequency shift, and call drops. This paper is trying to solve these problems by employing the Multiple-Input Multiple-Output technique and access control schemes. The goal is to provide higher quality of services such as data rate, reliability, and delay for train passengers. Physical layer performance analysis and access control schemes are proposed in a two-hop model. Handovers and service types are also considered. Simulation results show that proposed models and schemes perform better in improving the quality of services.

    2013-09-01

    In this article, we have proposed a blind, fragile and Region of Interest (ROI) lossless medical image watermarking (MIW) technique, providing an all-in-one solution tool to various medical data distribution and management issues like security, content authentication, safe archiving, controlled access retrieval, and captioning. The proposed scheme combines lossless data compression and encryption technique to embed electronic health record (EHR)/DICOM metadata, image hash, indexing keyword, doctor identification code and tamper localization information in the medical images. Extensive experiments (both subjective and objective) were carried out to evaluate performance of the proposed MIW technique. The findings offer suggestive evidence that the proposed MIW scheme is an effective all-in-one solution tool to various issues of medical information management domain. Moreover, given its relative simplicity, the proposed scheme can be applied to the medical images to serve in many medical applications concerned with privacy protection, safety, and management.

    Laparoscopic ovariohysterectomy using single-portal access was performed in nine selected owned dogs admitted for elective ovariohysterectomy and the surgical technique and outcomes were detailed. A multiport device (SILS Port, Covidien, USA) was placed at the umbilical area through a single 3 cm incision. Three cannulae were introduced in the multiport device through the access channels and laparoscopic ovariohysterectomy was performed using a 5-mm sealing device, a 5-mm articulating grasper and a 5-mm 30° laparoscope. The mean total operative time was 52.66±15.20 minutes and the mean skin incision during surgery was 3.09±0.20 cm. Of the nine cases examined, in the one with an ovarian tumour, the technique was converted to multiport laparoscopy introducing an additional 5-mm trocar. No surgical complications were encountered and intraoperative blood loss was minimum in all animals. Clashing of the instruments and reduced triangulation were the main limitations of this technique. The combination of articulated and straight instruments facilitated triangulation towards the surgical field and dissection capability. One month after surgery a complete wound healing was observed in all animals. The present data showed that ovariohysterectomy performed with a single-port access is technically feasible in dogs. The unique abdominal incision minimises the abdominal trauma with good cosmetic results. PMID:26568831

    Applications of rapid prototyping and Artificial Intelligence techniques to problems associated with Space Station-era information management systems are described. In particular, the work is centered on issues related to: (1) intelligent man-machine interfaces applied to scientific data user support, and (2) the requirement that intelligent information management systems (IIMS) be able to efficiently process metadata updates concerning types of data handled. The advanced IIMS represents functional capabilities driven almost entirely by the needs of potential users. Space Station-era scientific data projected to be generated is likely to be significantly greater than data currently processed and analyzed. Information about scientific data must be presented clearly, concisely, and with support features to allow users at all levels of expertise efficient and cost-effective data access. Additionally, mechanisms for allowing more efficient IIMS metadata update processes must be addressed. The work reported covers the following IIMS design aspects: IIMS data and metadata modeling, including the automatic updating of IIMS-contained metadata, IIMS user-system interface considerations, including significant problems associated with remote access, user profiles, and on-line tutorial capabilities, and development of an IIMS query and browse facility, including the capability to deal with spatial information. A working prototype has been developed and is being enhanced.

    The incidence of pulp canal obliteration following dental trauma has been reported to be approximately 4 - 24% and its management can be quite challenging for the practitioner. Locating the canal and negotiating it to full working length may lead to iatrogenic errors such as fractured instrument and perforation. This case report deals with such a case using the modified tip instrument technique to gain access and negotiate the canal to the apex followed by conventional root canal preparation and obturation.

    Background The insertion of a Totally Implantable Access Port (TIAP) is a routinely employed technique in patients who need a safe and permanent venous access. The number of TIAP implantations is increasing constantly mainly due to advanced treatment options for malignant diseases. Therefore it is important to identify the implantation technique which has the optimal benefit/risk ratio for the patient. Study design A single-centre, randomized, controlled superiority trial to compare two different TIAP implantation techniques. Sample size: 160 patients will be included and randomized intra-operatively. Eligibility criteria: Age equal or older than 18 years, patients scheduled for primary elective implantation of a TIAP in local anaesthesia and a signed informed consent. Primary endpoint: Primary success rate of the randomized technique. Intervention: Venae Sectio in combination with the Seldinger Technique (guide wire and a peel away sheath) will be used to place a TIAP. Reference treatment: Conventional Venae Sectio will be used with a direct insertion of the TIAP without guide wire or peel away sheath. Duration of study: Approximately 20 months. Organisation/Responsibility The trial will be conducted in compliance with the protocol and in accordance with the moral, ethical, and scientific principles governing clinical research as set out in the Declaration of Helsinki (1989) and Good Clinical Practice (GCP). The trial will also be carried out in keeping with local and regulatory requirements. The Klinisches Studienzentrum Chirurgie (KSC) – Centre of Clinical Trials in Surgery at the Department of Surgery, University Hospital Heidelberg is responsible for planning and conduction of the trial. Documentation of patient's data will be accomplished via electronical Case Report Files (eCRF) with MACRO®-Software by the KSC.

    Background: Keyhole craniotomies are increasingly being used for lesions of the skull base. Here we review our recent experience with these approaches for resection of intracranial meningiomas. Methods: Clinical and operative data were gathered on all patients treated with keyhole approaches by the senior author from January 2012 to June 2013. Thirty-one meningiomas were resected in 27 patients, including 9 supratentorial, 5 anterior fossa, 7 middle fossa, 6 posterior fossa, and 4 complex skull base tumors. Twenty-nine tumors were WHO Grade I, and 2 were Grade II.  Results: The mean operative time was 8 hours, 22 minutes (range, 2:55-16:14) for skull-base tumors, and 4 hours, 27 minutes (range, 1:45-7:13) for supratentorial tumors. Simpson Resection grades were as follows: Grade I = 8, II = 8, III = 1, IV = 15, V = 0. The median postoperative hospital stay was 4 days (range, 1-20 days). In the 9 patients presenting with some degree of visual loss, 7 saw improvement or complete resolution. In the 6 patients presenting with cranial nerve palsies, 4 experienced improvement or resolution of the deficit postoperatively. Four patients experienced new neurologic deficits, all of which were improved or resolved at the time of the last follow-up. Technical aspects and surgical nuances of these approaches for management of intracranial meningiomas are discussed.  Conclusions: With careful preoperative evaluation, keyhole approaches can be utilized singly or in combination to manage meningiomas in a wide variety of locations with satisfactory results.

    The prime NDT method selected for characterization of the waste is real-time x-radiography (RTR). An RTR system specifically designed for the TRU waste inspection is currently being used to develop the best techniques for waste certification. It is based on a standard 420 kV constant potential x-ray machine with a rare-earth fluorescing screen (gadolinium oxysulfide) functioning as an image converter. The low-light-level image produced on the screen is picked up by a CCTV camera with an image intensifier coupled to a plumbicon imaging tube. The system was designed for automated waste container handling and translation. Image analysis is not currently automated, although the CCTV image is digitized to allow signal averaging and edge enhancement through digital filtering. The digitized image is available through an IEEE 488 I/O port for more sophisticated computerized analysis.

    2015-01-01

    Background The mechanical thrombectomy (MT) for endovascular clot retrieval has dramatically improved successful revascularization and clinical outcome in selected acute stroke patients. MT is typically performed via a transfemoral approach, but catheterization of the occluded vessel can be problematic in cases of extensive vessel tortuosity. We describe a case of MT with the ‘ADAPT’ technique by direct carotid access due to an inability to catheterize the ICA by a transfemoral approach for acute cerebral ischemia in the setting of left MCA occlusion. Excellent angiographic and good clinical results were obtained without any complications. Case report An 80-year-old woman was admitted with a stroke by occlusion of the left MCA, with an NIHSS: 11, and an ASPECT: 7 in the CT. Under sedation a transfemoral angiography was performed, but after multiple attempts, it was impossible to make a stable catheterization of the left CCA. A transcervical approach was pursued. With ultrasound guidance the CCA was catheterized. Using the ‘ADAPT’ technique, we performed a successful MT. Post-procedure angiography (at 14 minutes) demonstrated recanalization of the entire left MCA (TICI: 3), without complications. The carotid access point was closed with a percutaneous closure. Control TC at 24 h showed a slight hypodensity in the left lenticular nucleus, and loss of gray-white matter differentiation in the adjacent cortex. Neurologically, the patient presented with progressive improvement. At discharge, she had an NIHSS: 0, mRS: 0 and Barthel: 100. Conclusions MT by direct carotid access is an effective alternative technique in those cases where it is not accessible by a transfemoral approach. PMID:26443297

  11. The reverse J arteriovenous graft configuration for hemodialysis access: rationale, technique, and outcomes.

    The long-term survival of patients on hemodialysis is often limited by the exhaustion of vascular access sites. A fundamental principle of vascular access surgery is that the arteriovenous (AV) access be placed as far distally in the arm as possible. This principle enhances the secondary patency of the AV grafts by preserving the proximal veins for AV graft revision and provides venous outflow for a new AV access to be placed more proximally in the extremity. The standard straight and looped AV graft configurations violate this principle by bypassing long segments of vein in the extremity that could be used for AV graft revision or new AV graft placement. We have developed a novel AV graft configuration that preserves venous outflow and enhances the longevity of each AV access site. The purpose of this review is to describe the reverse J AV graft technique and to report our outcomes with the procedure. Between February 2004 and April 2007, 26 AV grafts were placed using the reverse J configuration. Eighteen (69%) AV grafts were placed in the upper arm, 7 (27%) were placed in the forearm, and 1 (4%) was placed in the thigh. Median follow-up was 320 days. The secondary AV graft patency was 90 per cent at 6 months, 84 per cent at 12 months, and 84 per cent at 18 months. Five AV grafts were subsequently revised to a loop configuration. Overall patient survival was 85 per cent at 6 months, 68 per cent at 12 months, and 62 per cent at 18 months. Compared with the standard straight and looped AV graft configurations, the reverse J AV graft configuration preserves the length of venous outflow in the extremity for AV graft revision or new AV graft placement. Therefore, the reverse J configuration enhances the secondary patency of AV graft patency and AV access site longevity. PMID:18646480

    Catheter type, access technique, and the catheter position should be selected considering to the anticipated duration of PN aiming at the lowest complication risks (infectious and non-infectious). Long-term (>7–10 days) parenteral nutrition (PN) requires central venous access whereas for PN <3 weeks percutaneously inserted catheters and for PN >3 weeks subcutaneous tunnelled catheters or port systems are appropriate. CVC (central venous catheter) should be flushed with isotonic NaCl solution before and after PN application and during CVC occlusions. Strict indications are required for central venous access placement and the catheter should be removed as soon as possible if not required any more. Blood samples should not to be taken from the CVC. If catheter infection is suspected, peripheral blood-culture samples and culture samples from each catheter lumen should be taken simultaneously. Removal of the CVC should be carried out immediately if there are pronounced signs of local infection at the insertion site and/or clinical suspicion of catheter-induced sepsis. In case PN is indicated for a short period (max. 7–10 days), a peripheral venous access can be used if no hyperosmolar solutions (>800 mosm/L) or solutions with a high titration acidity or alkalinity are used. A peripheral venous catheter (PVC) can remain in situ for as long as it is clinically required unless there are signs of inflammation at the insertion site. PMID:20049083

    2003-05-01

    With increasing competition in the local and regional healthcare markets, and growing interest in assessing the effectiveness of services and patient outcomes, satisfaction measures are becoming prominent in evaluating the performance of the healthcare system. This study examines the independent effect of predisposing, enabling and medical need factors on perceived access to care with particular focus on insurance plans. A survey questionnaire is developed to investigate access limitations at three levels: (1) the health plan, (2) the individual provider(s) and (3) the healthcare organization. In addition, shortage of providers, residents' perceptions of their health status, satisfaction with access to care and socio-demographic indicators are incorporated into the analysis. Multivariate logistic regression is used to assess the independent effects of the above factors on a dichotomous dependent variable--residents' overall satisfaction with access to healthcare services. The most salient determinants of overall satisfaction with access to care were the type of health insurance plan, cost of insurance premiums, co-payments, difficulty with obtaining referrals, self-rated general health, the opportunity cost of taking time to see a provider (measured by the loss of hourly wages), marital status and the age factor over 80 years.

    2016-05-01

    Ureteropelvic junction obstruction (UPJO) is a common congenital abnormality that often presents in adulthood. Open dismembered pyeloplasty was considered the gold standard for the management of this condition; however, recent advancements in laparoscopic and robotic surgery have dramatically shifted the landscape to more minimally invasive techniques. A literature search of ureteropelvic junction obstruction, pyeloplasty, endopyelotomy, laparoscopic pyeloplasty, robotic pyeloplasty, and microlaparoscopic pyeloplasty was performed. A focus was placed on literature published since 2013. Minimally invasive laparoscopic and robotic techniques have become the gold standard for the management of UPJO. With the rise of robotic pyeloplasty, open repairs are becoming less frequent, while endoscopic treatments have remained stable. Minimally invasive (robotic) techniques have become the gold standard for the management of UPJO. Newer, even less-invasive techniques are also showing promise, but technical challenges still exist.

  5. Dynamic Key Management Schemes for Secure Group Access Control Using Hierarchical Clustering in Mobile Ad Hoc Networks

    NASA Astrophysics Data System (ADS)

    2008-11-01

    The applications of group computing and communication motivate the requirement to provide group access control in mobile ad hoc networks (MANETs). The operation in MANETs' groups performs a decentralized manner and accommodated membership dynamically. Moreover, due to lack of centralized control, MANETs' groups are inherently insecure and vulnerable to attacks from both within and outside the groups. Such features make access control more challenging in MANETs. Recently, several researchers have proposed group access control mechanisms in MANETs based on a variety of threshold signatures. However, these mechanisms cannot actually satisfy MANETs' dynamic environments. This is because the threshold-based mechanisms cannot be achieved when the number of members is not up to the threshold value. Hence, by combining the efficient elliptic curve cryptosystem, self-certified public key cryptosystem and secure filter technique, we construct dynamic key management schemes based on hierarchical clustering for securing group access control in MANETs. Specifically, the proposed schemes can constantly accomplish secure group access control only by renewing the secure filters of few cluster heads, when a cluster head joins or leaves a cross-cluster. In such a new way, we can find that the proposed group access control scheme can be very effective for securing practical applications in MANETs.

Too often patients access information about conditions they have self-diagnosed and bring it to the consultation with their physician, who then has to spend time disabusing the patients of the misinformation they have accumulated. Patients also return home from their initial consultation, access the Internet, and come up with all manner of promotional information from companies and even orthopedic practices that they want explained to them by their physician. It is the overwhelming conclusion of orthopedic specialists that this kind of Internet use is actually a burden for them in caring for patients and is not contributing to patient enlightenment. It does not have to be this way, if physicians will do just 2 things: first, create white papers for patients that address common current questions, such as surgical approach or bearing surfaces for implants and why we do what we do. This is a huge time saver and will preempt many questions. Second, develop their own website or select excellent nonprejudicial sites to which they can refer patients. To do less will invite a neverending parade of questions irrelevant to patient welfare. PMID:19751023

    Walser, Eric M.

    2012-08-15

    The subcutaneous venous access device (SVAD or 'port') is a critical component in the care of patients with chronic disease. The modern SVAD provides reliable access for blood withdrawal and medication administration with minimal disruption to a patient's lifestyle. Because of improved materials and catheter technology, today's ports are lighter and stronger and capable of high-pressure injections of contrast for cross-sectional imaging. The majority of SVAD placement occurs in interventional radiology departments due to their ability to provide this service at lower costs, lower, complication rates, and greater volumes. Port-insertion techniques vary depending on the operator, but all consist of catheter placement in the central venous circulation followed by subcutaneous pocket creation and port attachment to the catheter with fixation and closure of the pocket. Venous access challenges occasionally occur in patients with central vein occlusions, necessitating catheterization of collateral veins or port placement in alternate locations. Complications of SVADs include those associated with the procedure as well as short- (<30 days) and long-term problems. Procedural and early complications are quite rare due to the near-universal use of real-time ultrasound guidance for vein puncture, but they can include hematoma, catheter malposition, arrhythmias, and pneumothorax. Late problems include both thrombotic complications (native venous or port-catheter thrombosis) and infections (tunnel or pocket infections or catheter-associated bloodstream infections). Most guidelines suggest that 0.3 infections/1000 catheter days is an appropriate upper threshold for the insertion of SVADs.

    Frequency hopped frequency shift keying (FHFSK) and code division multiple access (CDMA) are two different modulation techniques for multiple users to communicate with a single receiver simultaneously. In July 2003, these two techniques were tested alongside each other in a shallow water coastal environment off the coast of Kauai. A variety of instruments were used to measure the prevailing oceanography, enabling detailed modeling of the channel. The channel was acoustically probed using LFM waveforms and m-sequences as well. We will present the results of demodulating the FHFSK and CDMA waveforms and discuss modeling the channel for the purpose of predicting multi-user communications performance. a)Michael B.

    SAM (Sequential Access through Meta-data) is the data access and job management system for the D0 high energy physics experiment at Fermilab. The SAM system is being developed and used to handle the Petabyte-scale experiment data, accessed by hundreds of D0 collaborators scattered around the world. In this paper, we present solutions to some of the distributed data processing problems from the perspective of real experience dealing with mission-critical data. We concentrate on the distributed disk caching, resource management and job control. The system has elements of the Grid Computing and has features applicable to data-intensive computing in general.

    2014-07-01

    With growing use of internet and exponential growth in amount of data to be stored and processed (known as ``big data''), the size of data centers has greatly increased. This, however, has resulted in significant increase in the power consumption of the data centers. For this reason, managing power consumption of data centers has become essential. In this paper, we highlight the need of achieving energy efficiency in data centers and survey several recent architectural techniques designed for power management of data centers. We also present a classification of these techniques based on their characteristics. This paper aims to provide insights into the techniques for improving energy efficiency of data centers and encourage the designers to invent novel solutions for managing the large power dissipation of data centers.

  11. Hoshin Kanri: a technique for strategic quality management.

    PubMed

    Tennant, C; Roberts, P A

    2000-01-01

    This paper describes a technique for Strategic Quality Management (SQM), known as Hoshin Kanri, which has been operated as a management system in many Japanese companies since the 1960s. It represents a core aspect of Japanese companies' management systems, and is stated as: the means by which the overall control system and Total Quality Management (TQM) are deployed. Hoshin Kanri is not particularly unique in its concept of establishing and tracking individual goals and objectives, but the manner in which the objectives and the means to achieve them are developed and deployed is. The problem with applying the concept of Strategic Quality Management (SQM) using Hoshin Kanri, is that it can tend to challenge the traditional authoritarian strategic planning models, which have become the paradigms of modern business. Yet Hoshin Kanri provides an appropriate tool for declaration of the strategic vision for the business while integrating goals and targets in a single holistic model. There have been various adaptations of Hoshin Kanri to align the technique to Western thinking and management approaches, yet outside Japan its significance has gone largely unreported. It is proposed that Hoshin Kanri is an effective methodology for SQM, which has a number of benefits over the more conventional planning techniques. The benefits of Hoshin Kanri as a tool for Strategic Quality Management (SQM) compared to conventional planning systems include: integration of strategic objectives with tactical daily management, the application of the plan-do-check-act cycle to business process management, parallel planning and execution methodology, company wide approach, improvements in communication, increased consensus and buy-in to goal setting, and cross-functional-management integration.

  14. An Intelligent Content Discovery Technique for Health Portal Content Management

    PubMed Central

    2014-01-01

    Background Continuous content management of health information portals is a feature vital for its sustainability and widespread acceptance. Knowledge and experience of a domain expert is essential for content management in the health domain. The rate of generation of online health resources is exponential and thereby manual examination for relevance to a specific topic and audience is a formidable challenge for domain experts. Intelligent content discovery for effective content management is a less researched topic. An existing expert-endorsed content repository can provide the necessary leverage to automatically identify relevant resources and evaluate qualitative metrics. Objective This paper reports on the design research towards an intelligent technique for automated content discovery and ranking for health information portals. The proposed technique aims to improve efficiency of the current mostly manual process of portal content management by utilising an existing expert-endorsed content repository as a supporting base and a benchmark to evaluate the suitability of new content Methods A model for content management was established based on a field study of potential users. The proposed technique is integral to this content management model and executes in several phases (ie, query construction, content search, text analytics and fuzzy multi-criteria ranking). The construction of multi-dimensional search queries with input from Wordnet, the use of multi-word and single-word terms as representative semantics for text analytics and the use of fuzzy multi-criteria ranking for subjective evaluation of quality metrics are original contributions reported in this paper. Results The feasibility of the proposed technique was examined with experiments conducted on an actual health information portal, the BCKOnline portal. Both intermediary and final results generated by the technique are presented in the paper and these help to establish benefits of the technique and

    2013-05-01

    As more enterprises are enticed to move data to a cloud environment to enhance data sharing and reduce operating costs by exploiting shared resources, concerns have risen over the ability to secure information within the cloud. This paper examines how a traditional Identity and Access Control (IDAM) architecture can be adapted to address security concerns of a cloud environment. We propose changing the paradigm of IDAM form a pure trust model to a risk based model will enable information to be protected securely in a cloud environment without impacting efficiencies of cloud environments.

  17. Utilization of inpatient and outpatient resources for the management of hemodialysis access complications.

    1996-08-01

    Complications of hemodialysis accesses are a major cause of morbidity in chronic hemodialysis patients. Although several investigators have reported on the utilization of inpatient services for hemodialysis access complications, there is a paucity of data regarding the utilization of outpatient services and temporary accesses for these complications. In this retrospective study, we identified all access-related inpatient admissions and outpatient encounters and procedures performed in an incident cohort of hemodialysis patients. Eighty-eight patients were followed for an average of 487.4 +/- 316.9 days, for a total of 119.1 patient-years of risk. The mean age was 57.0 +/- 14.6 years, with 55% females and 65% blacks; 31% of patients had diabetes mellitus as the primary cause of end-stage renal disease. Patients were referred to our nephrology practice a median of 56 days prior to the placement of a hemodialysis access and a median of 76 days prior to the initiation of hemodialysis. At the initiation of hemodialysis, 48 native arteriovenous fistulas and 40 polytetrafluoroethylene grafts were placed. Only 28 patients (31.8%) had a permanent access placed at least 14 days before the start of hemodialysis, resulting in the placement of 93 temporary accesses during the first week of dialysis therapy. Because of access complications, 21 patients had failure of their primary access, requiring the placement of 33 additional permanent accesses, including six native arteriovenous fistulas, 23 polytetrafluoroethylene grafts, and four permacaths, or an average of 0.28 new accesses per patient-year of risk. During the study period, 45 patients (51%) had at least one access complication. To manage these access complications, 25 fistulograms (0.21 per patient-year of risk) were performed and 116 additional temporary accesses (0.97 per patient-year of risk) were placed, including 50 femoral (43.1%), 52 subclavian (44.8%), and 14 internal jugular (12.1%) catheters.

    2006-03-01

    Infertility affects one in seven couples in the United Kingdom. The National Institute for Clinical Excellence (NICE) issued guidance on the management of the infertile couple in February 2004, which included the statement "for the assessment of tubal damage, women not known to have co-morbidities (pelvic inflammatory disease, endometriosis or previous ectopic pregnancy) should be offered hysterosalpingography (HSG)". We made HSG available to six general practices in Newcastle upon Tyne as an open access investigation. Our aim was to evaluate the uptake of open access HSG, speed of access to specialist services and the quality of the information recorded in the referral letter. Using hospital clinical records we tracked the outcome of all infertile couples from the six pilot practices over a nine-month period. Of the 39 referrals identified, 10 women were eligible for open access HSG, of which six HSGs were organized by GPs. Couples who had open access HSG reached a diagnosis and management plan four weeks earlier than those who were referred directly (mean difference 4.0 weeks, 95% confidence interval (CI) -8.8 to 0.4 weeks). The information recorded in the referral letter was generally poor. However, all referrals made via the open access HSG service had the prerequisite tests done. Open access HSG allowed prompter access to specialist services with more complete information passed on in the referral letter. Open access HSG was used in 15% of all infertile couples and 60% of those who fitted the criteria for its use. Open access HSG together with semen analysis and endocrine blood tests may allow GPs to manage the initial stages of the infertile couple and make a diagnosis. PMID:16581721

  10. Carrier Estimation Using Classic Spectral Estimation Techniques for the Proposed Demand Assignment Multiple Access Service

    NASA Technical Reports Server (NTRS)

    Scaife, Bradley James

    1999-01-01

    In any satellite communication, the Doppler shift associated with the satellite's position and velocity must be calculated in order to determine the carrier frequency. If the satellite state vector is unknown then some estimate must be formed of the Doppler-shifted carrier frequency. One elementary technique is to examine the signal spectrum and base the estimate on the dominant spectral component. If, however, the carrier is spread (as in most satellite communications) this technique may fail unless the chip rate-to-data rate ratio (processing gain) associated with the carrier is small. In this case, there may be enough spectral energy to allow peak detection against a noise background. In this thesis, we present a method to estimate the frequency (without knowledge of the Doppler shift) of a spread-spectrum carrier assuming a small processing gain and binary-phase shift keying (BPSK) modulation. Our method relies on an averaged discrete Fourier transform along with peak detection on spectral match filtered data. We provide theory and simulation results indicating the accuracy of this method. In addition, we will describe an all-digital hardware design based around a Motorola DSP56303 and high-speed A/D which implements this technique in real-time. The hardware design is to be used in NMSU's implementation of NASA's demand assignment, multiple access (DAMA) service.

    1978-01-01

    APL provides convenient associative data manipulation functions in a high level language. Six statements were added to PL/1 via a preprocessor: CREATE, INSERT, FIND, FOR EACH, REMOVE, and DELETE. They allow complete control of all data base operations. During execution, data base management programs perform the functions required to support the APL language. VAAM is the data base management system designed to support the APL language. APL/VAAM is used by CADANCE, an interactive graphic computer system. VAAM is designed to support heavily referenced files. Virtual memory files, which utilize the paging mechanism of the operating system, are used. VAAM supports a full network data structure. The two basic blocks in a VAAM file are entities and sets. Entities are the basic information element and correspond to PL/1 based structures defined by the user. Sets contain the relationship information and are implemented as arrays.

    PubMed

    Abd el Ghany, A B; Holley, M P; Cuschieri, A

    1989-01-01

    A laparoscopic-guided technique of percutaneous gallstone fragmentation/removal has been developed in the pig. The procedure entails the creation of a percutaneous access cholecystostomy. The access tract can be safely dilated after 7 days to F16, thereby allowing the introduction of both the Olympus flexible and the Berci-Shore rigid choledochoscopes. Following endoscopic occlusion of the cystic duct by a biliary balloon catheter, stone fragmentation can be conducted under direct visual control. In this particular study, electrohydraulic lithotripsy was performed of human cholesterol and bile-pigment stones inserted into the gallbladder of 16 pigs. The gallstone debris resulting from lithotripsy was then washed out with saline. Larger residual fragments could easily be extracted with the Dormia basket under visual guidance. There was a significant positive correlation between stone size (r = 0.98) and weight (r = 0.96) and the number of pulses needed to achieve satisfactory stone fragmentation. The gross composition of the stones (predominantly cholesterol or pigment) did not influence the number of pulses required. Electrohydraulic lithotripsy caused an explosion effect (the fragments hit the gallbladder wall), causing submucosal haematoma formation. This, however, was not followed by any untoward effect until sacrifice of the animals 10-16 weeks later. Electrohydraulic shocks delivered to the gallbladder wall itself resulted in larger haematoma formation and breach of the gallbladder mucosa with active bleeding into the gallbladder lumen, but again no instance of gallbladder perforation was encountered.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2530642

    SciTech Connect

    Siu, K.Y.; Wu, Y.; Ren, W.

    1998-11-01

    The ATM Forum is currently discussing the need for a new best-effort service called UBR+, which is an enhancement to the existing UBR service, to support data traffic. The objective of the UBR+ service is to provide each user with a minimum service rate guarantee and a fair access to any excess available bandwidth. In this paper, the authors present a new efficient scheme for supporting this service. The key advantage of the scheme is that it employs only FIFO queueing (instead of per-VC queueing) and admits simple implementation in ATM switches. The ideas involve a simple scheduling mechanism that is based on per-VC queueing and incorporate the virtual queueing technique that can efficiently emulate per-VC queueing on a shared FIFO queue. Simulation results are presented to show that the schemes can deliver almost ideal performance for supporting the new service requirements of UBR+.

    Limited retrievability is a major disadvantage of cement-retained implant restorations. Despite great progress in locating the abutment screw within crowns, the existing techniques are based on prior data or prefabricated devices and require significant work. This study introduces a new procedure for fabricating a guide template to drill a screw access hole using a double-step superimposition technique that incorporates intraoral optical scanning, cone beam computed tomography, and dental design software. The double-step superimposition technique with computer-aided design/computer-assisted manufacturing technology can enhance the convenience and accuracy of drilling the screw-access hole.

    At the request of the Department of Energy (DOE) Office of Science (SC), Lawrence Livermore National Laboratory (LLNL) hosted a two-day Risk Management Techniques and Practice (RMTAP) workshop held September 18-19 at the Hotel Nikko in San Francisco. The purpose of the workshop, which was sponsored by the SC/Advanced Scientific Computing Research (ASCR) program and the National Nuclear Security Administration (NNSA)/Advanced Simulation and Computing (ASC) program, was to assess current and emerging techniques, practices, and lessons learned for effectively identifying, understanding, managing, and mitigating the risks associated with acquiring leading-edge computing systems at high-performance computing centers (HPCCs). Representatives from fifteen high-performance computing (HPC) organizations, four HPC vendor partners, and three government agencies attended the workshop. The overall workshop findings were: (1) Standard risk management techniques and tools are in the aggregate applicable to projects at HPCCs and are commonly employed by the HPC community; (2) HPC projects have characteristics that necessitate a tailoring of the standard risk management practices; (3) All HPCC acquisition projects can benefit by employing risk management, but the specific choice of risk management processes and tools is less important to the success of the project; (4) The special relationship between the HPCCs and HPC vendors must be reflected in the risk management strategy; (5) Best practices findings include developing a prioritized risk register with special attention to the top risks, establishing a practice of regular meetings and status updates with the platform partner, supporting regular and open reviews that engage the interests and expertise of a wide range of staff and stakeholders, and documenting and sharing the acquisition/build/deployment experience; and (6) Top risk categories include system scaling issues, request for proposal/contract and acceptance testing, and

    Background: Surgical reconstruction of segmental skeletal defects represents a true challenge for the orthopedic surgeons. Recently, Masquelet et al. described a two-stage technique for reconstruction of bone defects, known as the induced membrane technique. The aim of this study is to assess the results of the induced membrane technique in the management of segmental skeletal defects resulting from debridement of bone infection. Materials and Methods: Seventeen patients with segmental skeletal defects were treated in our institution by the induced membrane technique. The average age of the patients was 43 years (range 26- 58 years). The causes of the defects were infected gap nonunion in 12 cases and debridement of osteomyelitis in 5 cases. The defects were located in the tibia (n = 13) and the femur (n = 4). The mean defect was 7 cm (range 4 cm - 11 cm). All cases were treated by the induced membrane technique in two-stages. Results: Bone union happened in 14 patients. The limb length discrepancy did not exceed 2.5 cm in the healed cases. The mean time of healing was 10 months (range 6-19 months). The complications included nonunion of the graft in five cases, failure of graft maturation in two cases, reactivation of infection in two cases and refracture after removal of the frame in one case. These complications were managed during the course of treatment and they did not affect the final outcome in all patients except three. Conclusion: The induced membrane technique is a valid option for the management of segmental skeletal defects. It is a simple and straight forward procedure, but the time required for growth and maturation of the graft is relatively long. PMID:26806972

    Discovering Earth science data can be complex if the catalog holding the data lacks structure. Controlled keyword vocabularies within metadata catalogues can improve data discovery. NASA's Global Change Master Directory's (GCMD) Keyword Management System (KMS) is a recently released a RESTful web service for managing and providing access to controlled keywords (science keywords, service keywords, platforms, instruments, providers, locations, projects, data resolution, etc.). The KMS introduces a completely new paradigm for the use and management of the keywords and allows access to these keywords as SKOS Concepts (RDF), OWL, standard XML, and CSV. A universally unique identifier (UUID) is automatically assigned to each keyword, which uniquely identifies each concept and its associated information. A component of the KMS is the keyword manager, an internal tool that allows GCMD science coordinators to manage concepts. This includes adding, modifying, and deleting broader, narrower, or related concepts and associated definitions. The controlled keyword vocabulary represents over 20 years of effort and collaboration with the Earth science community. The maintenance, stability, and ongoing vigilance in maintaining mutually exclusive and parallel keyword lists is important for a "normalized" search and discovery, and provides a unique advantage for the science community. Modifications and additions are made based on community suggestions and internal review. To help maintain keyword integrity, science keyword rules and procedures for modification of keywords were developed. This poster will highlight the use of the KMS as a beneficial service for the stewardship and access of the GCMD keywords. Users will learn how to access the KMS and utilize the keywords. Best practices for managing an extensive keyword hierarchy will also be discussed. Participants will learn the process for making keyword suggestions, which subsequently help in building a controlled keyword

    Mercury is a federated metadata harvesting, search and retrieval tool based on both open source software and software developed at Oak Ridge National Laboratory. It was originally developed for NASA, and the Mercury development consortium now includes funding from NASA, USGS, and DOE. A major new version of Mercury was developed during 2007 and released in early 2008. This new version provides orders of magnitude improvements in search speed, support for additional metadata formats, integration with Google Maps for spatial queries, support for RSS delivery of search results, and ready customization to meet the needs of the multiple projects which use Mercury. For the end users, Mercury provides a single portal to very quickly search for data and information contained in disparate data management systems. It collects metadata and key data from contributing project servers distributed around the world and builds a centralized index. The Mercury search interfaces then allow ! the users to perform simple, fielded, spatial and temporal searches across these metadata sources. This centralized repository of metadata with distributed data sources provides extremely fast search results to the user, while allowing data providers to advertise the availability of their data and maintain complete control and ownership of that data.

  4. Remote sensing techniques in cultural resource management archaeology

    Cultural resource management archaeology in the United States concerns compliance with legislation set in place to protect archaeological resources from the impact of modern activities. Traditionally, surface collection, shovel testing, test excavation, and mechanical stripping are used in these projects. These methods are expensive, time consuming, and may poorly represent the features within archaeological sites. The use of remote sensing techniques in cultural resource management archaeology may provide an answer to these problems. Near-surface geophysical techniques, including magnetometry, resistivity, electromagnetics, and ground penetrating radar, have proven to be particularly successful at efficiently locating archaeological features. Research has also indicated airborne and satellite remote sensing may hold some promise in the future for large-scale archaeological survey, although this is difficult in many areas of the world where ground cover reflect archaeological features in an indirect manner. A cost simulation of a hypothetical data recovery project on a large complex site in Mississippi is presented to illustrate the potential advantages of remote sensing in a cultural resource management setting. The results indicate these techniques can save a substantial amount of time and money for these projects.

    Background: The current distribution of and access to health services along with the future health needs of the population have prompted wide application of Geographic Information Systems (GISs). During recent years, GIS has been used in public health management for planning and organization of healthcare services. This study investigates geographical accessibility of residential areas in Bandar Abbas, Iran to healthcare services. Methods: Accessibility was evaluated by using Floating Catchment Area (FCA), minimum distance methods and Response Time (RT) accessibility technique. Results: More accurate measures of distances in Bandar Abbas, illustrated that Euclidean distances were not strongly correlated with network distances. The RT accessibility technique that utilizes shortest network path and time distances, presented detailed information about all the possible positions of the patients with respect to available healthcare services based on optimum and critical response times. Conclusion: Locations of public health services in Bandar Abbas were not related to the sites of populations. The RT accessibility technique provides a reasonably sensitive and robust evaluation of accessibility. PMID:26188808

    Satellite remote sensing and GIS have emerged as the most powerful tools for inventorying, monitoring and management of natural resources and environment. In the special context of wetland ecosystems, remotely sensed data from orbital platforms have been extensively used in India for the inventory, monitoring and preparation of action plans for conservation and management. First scientific inventory of wetlands in India was carried out in 1998 by Space Applications Centre (ISRO), Ahmedabad using indigenous IRS (Indian Remote Sensing Satellite) data of 1992-93 timeframe, which stimulated extensive use of geospatial techniques for wetland conservation and management. Subsequently, with advances in GIS, studies were carried out for development of Wetland Information System for a state (West Bengal) and for Loktak lake wetland (a Ramsar site) as a prelude to National Wetland Information System. Research has also been carried out for preparation of action plans especially for Ramsar sites in the country. In a novel research, use of the geospatial technology has also been demonstrated for biodiversity conservation using landscape ecological metrics. A country-wide estimate of emission of methane, a Green House Gas, from wetlands has also been made using MODIS data. Present article critically reviews the work carried out in India for wetland conservation and management using geospatial techniques. PMID:24486190

    In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity noise (PIIN) and multiple-access interference (MAI) in the optical domain. Analytical results show that for 35 simultaneous users transmitting at data rate of 622 Mbps, the bit-error rate (BER) = 1.4x10^-28 for SPD technique is much better compared to 9.3x10^-6 and 9.6x10^-3 for the modified-AND as well as the AND detection techniques, respectively. Moreover, we verified the improved performance afforded by the proposed technique using data transmission simulations.

    The intent of bridge management systems is to help engineers and managers determine when and where to spend bridge funds such that commerce and the motoring public needs are satisfied. A major shortcoming which states are experiencing is the NBIS data available is insufficient to perform certain functions required by new bridge management systems, such as modeling bridge deterioration and predicting costs. This paper will investigate how modal based nondestructive damage evaluation techniques can be integrated into bridge management using quality management principles. First, quality from the manufacturing perspective will be summarized. Next, the implementation of quality management in design and construction will be reinterpreted for bridge management. Based on this, a theory of approach will be formulated to improve the productivity of a highway transportation system.

    1989-01-01

    A worldwide aeronautical mobile satellite system is about to become operational. The system architecture and access methods have been debated extensively, resulting in the selection of Time Division Multiplexing/Time Division Multiple Access (TDM/TDMA) access for packet data, and Single Channel Per Carrier (SCPC) for voice. These have become standards for airline use, and also satisfy the known requirements of ICAO for safety related communications. Voice communications are expected to absorb a high proportion of satellite bandwidth and power in the future. Here, it is explained why INMARSAT selected Frequency Division Multiple Access/SCPC satellite access for this application.

    This study examined service user characteristics and determinants of access for enrollees in integrated EAP/behavioral health versus standard managed behavioral health care plans. A national managed behavioral health care organization’s claims data from 2004 were used. Integrated plan service users were more likely to be employees rather than dependents, and to be diagnosed with adjustment disorder. Logistic regression analyses found greater likelihood in integrated plans of accessing behavioral health services (OR 1.20, CI 1.17–1.24), and substance abuse services specifically (OR 1.23, CI 1.06–1.43). Results are consistent with the concept that EAP benefits may increase access and address problems earlier. PMID:19690952

    1997-01-01

    This article reports on differences in satisfaction with provider choice, access to care, and plan costs and coverage between women enrolled in fee-for-service and those in managed car plans. It also examines differences in satisfaction, access, and costs and coverage between higher and lower income women and between those in reported fair or poor health and those in excellent or good health, among women in managed care plans. The data for this study are from The Commonwealth Fund's 1994 Managed Care Survey, which included 1,544 women with employer- or union-sponsored insurance in Boston, Los Angeles, and Miami. The study found that women in managed care were less satisfied with provider choice and access to services, but more satisfied with out-of-pocket costs for services and the range of services covered. Both low-income women and those in fair to poor health reported more problems with access barriers than did either higher income women or those in excellent or good health. PMID:9127994

    This is a case report describing the ultrasound-guided placement of a peripheral intravenous catheter into the internal jugular vein of a patient with difficult vascular access. Although this technique has been described in the past, this case is novel in that the Seldinger technique was used to place the catheter. This allows for safer placement of a longer catheter (2.25″) without the need for venous dilation, which is potentially hazardous. PMID:26823937

    Monitoring methods used in fisheries-management assessments were examined and their potential applicability in confirmatory impact monitoring were evaluated using case studies from selected nuclear power plants. A report on Task I of the project examined the application of Catch-Per-Unit-Effort (CPUE) techniques in monitoring programs at riverine, large lake and ocean sites. Included in this final report is an examination of CPUE data for the Oconee Nuclear Plant on Lake Keowee, a reservoir site. This report also presents a summary of results obtained over the life of the project and guidelines for designing and implementing data collection programs and for data analysis and interpretation. Analysis of monitoring data from Lake Keowee confirmed findings from previous analyses of surveys at nuclear power plants on large lakes, rivers and coastal sites. CPUE techniques as applied to these monitoring programs do not provide data necessary to separate changes induced by plant operation from naturally occurring changes.

    Pancreaticoduodenectomy (Whipple's procedure) remains the only definitive treatment option for tumors of the periampullary region. The most common and life-threatening complications following the procedure are pancreatic anastomotic leakage and subsequent fistula formation. When these complications occur, treatment strategy depends on the severity of anastomotic leakage, with patients with severe leakages requiring reoperation. The optimal surgical method used for reoperation is selected from among different options such as wide drainage, definitive demolition of the pancreaticojejunal anastomosis and performing a new one, or completion pancreatectomy. Here we present a novel, simple technique to manage severe pancreatic leakage via ligamentum teres hepatis patch. PMID:27403368

    Current arthroscopic surgical techniques for the management of proximal biceps tendon disorders encompass 3 commonly advocated procedures: proximal biceps anchor reattachment (superior labrum anterior to posterior or SLAP repair), biceps tenotomy, and arthroscopic biceps tenodesis. The indications for each procedure vary based on injury pattern, symptomatic presentation, concomitant pathologic abnormality, and most notably, patient factors, such as age, functional demand, and specific sport or activity participation. Outcomes after SLAP repair are generally favorable, although recent studies have found biceps tenodesis to be the preferred treatment for certain patient populations. PMID:26614472

    A U.S. Geological Survey team is working with several providers to establish standard data services for the climate projection data they host. To meet the needs of climate adaptation science and landscape management communities, the team is establishing a set of climate index calculation algorithms that will consume data from various providers and provide directly useful data derivatives. Climate projections coming from various scenarios, modeling centers, and downscaling methods are increasing in number and size. Global change impact modeling and assessment, generally, requires inputs in the form of climate indices or values derived from raw climate projections. This requirement puts a large burden on a community not familiar with climate data formats, semantics, and processing techniques and requires storage capacity and computing resources out of the reach of most. In order to fully understand the implications of our best available climate projections, assessments must take into account an ensemble of climate projections and potentially a range of parameters for calculation of climate indices. These requirements around data access and processing are not unique from project to project, or even among projected climate data sets, pointing to the need for a reusable tool to generate climate indices. The U.S. Geological Survey has developed a pilot application and supporting web service framework that automates the generation of climate indices. The web service framework consists of standards-based data servers and a data integration broker. The resulting system allows data producers to publish and maintain ownership of their data and data consumers to access climate derivatives via a simple to use "data product ordering" workflow. Data access and processing is completed on enterprise "cloud" computing resources and only the relatively small, derived climate indices are delivered to the scientist or land manager. These services will assist the scientific and land

    2015-04-01

    Spasticity is often experienced by individuals with injury or illness of the central nervous system from etiologies such as stroke, spinal cord injury, brain injury, multiple sclerosis, or other neurologic conditions. Although spasticity may provide benefits in some patients, it more often leads to complications negatively impacting the patient. Nonpharmacologic treatment options often do not provide long-term reduction of spasticity, and systemic interventions, such as oral medications, can have intolerable side effects. The use of botulinum neurotoxin injections is one option for management of focal spasticity. Several localization techniques are available to physicians that allow for identification of the selected target muscles. These methods include anatomic localization in isolation or in conjunction with electromyography guidance, electrical stimulation guidance, or ultrasound guidance. This article will focus on further description of each of these techniques in relation to the treatment of adult spasticity and will discuss the advantages and disadvantages of each technique, as well as review the literature comparing the techniques.

    The obstetric experience alongside scientific evidences in literature indicate several management techniques during the expulsive period of labour to minimize obstetric complications. Among the various methods that can be used for the protection of the perineum during the expulsive phase, some are performed prepartum (perineum massage), while most are used during childbirth. Among the second group, progressively increasing importance is assumed by the manual techniques to protect the perineum (using the "hands-on" and "hands-off") and by episiotomy. These techniques, when used in accordance to the guidelines, may favour the reduction of adverse outcomes for both the mother and the newborn, both immediately after birth and after a longer time. The midwife should be aware of the evidences in literature so that a critical analysis of the available techniques can be made and put in action during the expulsive phase in order to protect the mother and the foetus from any unfavourable outcomes. Currently, clinical evidence in literature is directing obstetric and medical staff towards a careful analysis of the maternal-foetal parameters, in order to achieve a precise assessment of the risks factors of intrapartum and postpartum outcomes. Increasingly, there is the need for close collaboration between the midwife and medical staff to ensure proper personalized assistance based on the peculiar characteristics of the woman and the fetus.

    The optical disc has become a new technique for mass digital data storage of X-ray images from examinations and films in todays hospitals. Up to 36,000 X-ray images can be stored on one side of a 12-inch disc by melting holes 0.015 mils in size in an ablative material such as tellerium with a laser beam. This unique characteristic makes the disc suitable for storage and retrieval of X-rays in a record and playback system in either a single disc or multiple disc "jukebox" configuration. Doctors, nurses, technicians and other hospital personnel can call up a particular X-ray in less than 0.6 of a second in an on-line single disc system and up to less than 6 seconds in an on-line "jukebox" system. The jukebox is configured to hold up to 100 discs, thus storing 3,600,000 X-rays in hospitals with a bed size of greater than 500. The estimated exposed films on file in those hospitals is 327,400,000 and the estimated annual X-ray exams are 44,300. Thus, a single disc system could be used for an all electronic X-ray scanning system for annual X-ray exams. The jukebox configuration, which has expansion capability for servicing multiple simultaneous user request, can be applied to large archival mass storage. These systems could store the existing exposed films in hospitals with bed size greater than 500 at record and playback data rates of 50 Mb/s with access times of less than 15 seconds.

    1989-02-01

    Most people see little similarity between a battlefield manager and a natural resource manager. However, except for the element of time, many striking similarities may be drawn. Indeed, there are more differences between the tranquil scenes of mountain scenery, forests, rivers or grasslands and bomb scarred battlefields where survival is often the prime objective. The similarities center around the basic need for information upon which good decisions may be made. Both managers of battlefields and of natural resources require accurate, timely, and continuous information about changing conditions. Based on this information, they each make decisions to conserve the materials and resources under their charge. Their common goal is to serve the needs of the people in their society. On the one hand, the goal is victory in battle to perpetuate a way of life or a political system. On the other, the goal is victory in an ongoing battle against fire, insects, disease, soil erosion, vandalism, theft, and misuse in general. Here, a desire to maintain natural resources in a productive and healthy condition prevails. The objective of the natural resource manager is to keep natural resources in such a condition that they will continue to meet the needs and wants of the people who claim them for their common good. In this paper, the different needs for information are compared and a little history of some of the quasi-military aspects of resource management is given. Needs for information are compared and current uses of data acquisition techniques are reviewed. Similarities and differences are discussed and future opportunities for cooperation in data acquisition are outlined.

  7. Barriers of access to care in a managed competition model: lessons from Colombia

    2010-01-01

    Background The health sector reform in Colombia, initiated by Law 100 (1993) that introduced a managed competition model, is generally presented as a successful experience of improving access to care through a health insurance regulated market. The study's objective is to improve our understanding of the factors influencing access to the continuum of care in the Colombian managed competition model, from the social actors' point of view. Methods An exploratory, descriptive-interpretative qualitative study was carried out, based on case studies of four healthcare networks in rural and urban areas. Individual semi-structured interviews were conducted to a three stage theoretical sample: I) cases, II) providers and III) informants: insured and uninsured users (35), health professionals (51), administrative personnel (20), and providers' (18) and insurers' (10) managers. Narrative content analysis was conducted; segmented by cases, informant's groups and themes. Results Access, particularly to secondary care, is perceived as complex due to four groups of obstacles with synergetic effects: segmented insurance design with insufficient services covered; insurers' managed care and purchasing mechanisms; providers' networks structural and organizational limitations; and, poor living conditions. Insurers' and providers' values based on economic profit permeate all factors. Variations became apparent between the two geographical areas and insurance schemes. In the urban areas barriers related to market functioning predominate, whereas in the rural areas structural deficiencies in health services are linked to insufficient public funding. While financial obstacles are dominant in the subsidized regime, in the contributory scheme supply shortage prevails, related to insufficient private investment. Conclusions The results show how in the Colombian healthcare system structural and organizational barriers to care access, that are common in developing countries, are widened by both

    With the increased use of implanted venous access devices (IVADs) for continuous long-term venous access, several techniques such as percutaneous endovascular fibrin sheath removal, have been described, to maintain catheter function. Most standard techniques do not capture the stripped fibrin sheath, which is subsequently released in the pulmonary circulation and may lead to symptomatic pulmonary embolism. The presented case describes an endovascular technique which includes stripping, capture, and removal of fibrin sheath using a novel filter device. A 64-year-old woman presented with IVAD dysfunction. Stripping was performed using a co-axial snare to the filter to capture the fibrin sheath. The captured fragment was subsequently removed for visual and pathological verification. No immediate complication was observed and the patient was discharged the day of the procedure. PMID:27016091

    Natural resources management typically requires prediction of environmental changes over long time periods. In the case of forest management, for example, decisions can affect timber production, water catchment properties, recreational values, aesthetic values, energy usage or employment opportunities. This paper presents an application of advanced visualization techniques in combination with a geographic information system and linear programming in this context. The emphasis is on provision of visual feedback on the outcome of decision options. This main interactive window include a 3D view of the management area based initially on remote sensing imagery draped on a digital terrain model. Also on screen are a slider for time (from the present to 200 years hence), and sliders for decision variables such as required job support level, extent of habit conservation or catchment performance. As the time, or the decision variables are altered by the user the result is presented through replacement of textures in the 3D view to represent the changes in land cover.

    Although information access control models have been developed and applied to various applications, few of the previous works have addressed the issue of managing information access in the combined context of team collaboration and workflow. To facilitate this requirement, we have enhanced the Role-Based Access Control (RBAC) model through formulating universal constraints, defining bridging entities and contributing attributes, extending access permissions to include workflow contexts, synthesizing a role-based access delegation model to target on specific objects, and developing domain ontologies as instantiations of the general model to particular applications. We have successfully applied this model to the New York State HIV Clinical Education Initiative (CEI) project to address the specific needs of information management in collaborative processes. An initial evaluation has shown this model achieved a high level of agreement with an existing system when applied to 4576 cases (kappa=0.801). Comparing to a reference standard, the sensitivity and specificity of the enhanced RBAC model were at the level of 97-100%. These results indicate that the enhanced RBAC model can be effectively used for information access management in context of team collaboration and workflow to coordinate clinical education programs. Future research is required to incrementally develop additional types of universal constraints, to further investigate how the workflow context and access delegation can be enriched to support the various needs on information access management in collaborative processes, and to examine the generalizability of the enhanced RBAC model for other applications in clinical education, biomedical research, and patient care.

    Smart Sensor Networks are becoming important target detection and tracking tools. The challenging problems in such networks include the sensor fusion, data management and communication schemes. This work discusses techniques used to distribute sensor management and multi-target tracking responsibilities across an ad hoc, self-healing cluster of sensor nodes. Although miniaturized computing resources possess the ability to host complex tracking and data fusion algorithms, there still exist inherent bandwidth constraints on the RF channel. Therefore, special attention is placed on the reduction of node-to-node communications within the cluster by minimizing unsolicited messaging, and distributing the sensor fusion and tracking tasks onto local portions of the network. Several challenging problems are addressed in this work including track initialization and conflict resolution, track ownership handling, and communication control optimization. Emphasis is also placed on increasing the overall robustness of the sensor cluster through independent decision capabilities on all sensor nodes. Track initiation is performed using collaborative sensing within a neighborhood of sensor nodes, allowing each node to independently determine if initial track ownership should be assumed. This autonomous track initiation prevents the formation of duplicate tracks while eliminating the need for a central "management" node to assign tracking responsibilities. Track update is performed as an ownership node requests sensor reports from neighboring nodes based on track error covariance and the neighboring nodes geo-positional location. Track ownership is periodically recomputed using propagated track states to determine which sensing node provides the desired coverage characteristics. High fidelity multi-target simulation results are presented, indicating the distribution of sensor management and tracking capabilities to not only reduce communication bandwidth consumption, but to also

    We present SPIDR III, a web based data access, visualization and data management system for the space environment community, allowing a solar terrestrial physics customer to intelligently access and manage historical space physics data for integration with environmental models and space weather forecasts. SPIDR III is the newly redesigned Space Physics Interactive Resource (SPIDR) web application and was redesigned with input from it's user community via an intensive usability study. We will present on SPIDR III's new features, improved use and on lessons learned in usability and federating multi-source data. In 2004, SPIDR II underwent extensive rework yielding a completely redesigned interface for improved user interaction and the addition of many enhanced and complex features. The usability alterations were motivated in large part by a usability study performed by outside professional site reviewers and involving key data managers and current SPIDR II users. SPIDR III is built following the application direct to data archive paradigm, using Web Services both for internal and external exchange of data and information. It is now a framework and application set of Web Services. This application suite is fully open source and is designed to operate as a standalone VO as well as seamlessly integrate with other existing VOs. This extensible and open design yields easy mirroring worldwide for free and open exchange of scientific data and information. Data managed by SPIDR includes Geomagnetic Indices, GOES, Ionospheric, and DMSP which is archived/ingested from many data providers including WDC, IIWG, SAO, HDF, AFCCC, SEC, NASA, and this list is easily extendable.

    2009-01-01

    Objective To evaluate the impact of Medicaid managed care organizations (MCO) on health care access for adults with disabilities (AWDs). Data Sources Mandatory and voluntary enrollment data for AWDs in Medicaid MCOs in each county were merged with the Medical Expenditure Panel Survey and the Area Resource File for 1996–2004. Study Design I use logit regression and two evaluation perspectives to compare access and preventive care for AWDs in Medicaid MCOs with FFS. From the state's perspective, I compare AWDs in counties with mandatory, voluntary, and no MCOs. From the enrollee's perspective, I compare AWDs who must enroll in an MCO or FFS to those who may choose between them. Principal Findings Mandatory MCO enrollees are 24.9 percent more likely to wait >30 minutes to see a provider, 32 percent more likely to report a problem accessing a specialist, and 10 percent less likely to receive a flu shot within the past year. These differences persist from the state evaluation perspective. Conclusions States should not expect a dramatic change in health care access when they implement Medicaid MCOs to deliver care to the adult disabled population. However, continued attention to specialty care access is warranted for mandatory MCO enrollees. PMID:19555397

    Fish discards and by-catch issues are highly topical subjects that are permanently under a social focus. Two main approaches are being considered to address this discard problem: reducing the by-catch and increasing by-catch utilization. Interest in increased by-catch valorization may arise from a greater demand for fish products, such as the development of new markets for previously discarded species, the use of low-value specimens for aquaculture or the creation of value-added fish products for the food, pharmaceutical or cosmetic industries. However, contaminants present in fish discards may be transferred to their valorized products, leading to possible long-term bioaccumulation and subsequent adverse health effects. In this valorization framework, the aim is to promote responsible and sustainable management of marine resources. The pollutant levels in catches from European fisheries and the best available decontamination techniques for marine valorized discards/by-products are compiled and analyzed in this work.

    Dental anxiety develops from a vicious cycle of bodily arousal from dental stimuli, cognitive interpretation and ineffective coping all working in a runaway feedback loop. Behavioral management strategies (BMT) aim at cognitive reorientation, which results in better compliance with instruction. This paper therefore tried to find out possible factors that influence the effective use of BMT during child dental management during treatment by dental operators in Nigeria. The levels of anxiety pre and post treatment were assessed using the short form of the dental version of the Child Fear Survey Schedule. Also, the type of treatment given to the child, the types and number of behavioral strategies employed during dental management as well as the gender and age of the child were noted. The professional status of the attending dental operator was also noted. Prior to the commencement of the study, the five students in the final year, who were to attend to the children in this study received one week training on the psychological management of dental anxiety in children. Results obtained from the dental operators were compared. The type of treatment received by the child did not significantly affect the dental anxiety score. The number of techniques combined by house officers and senior registrars were significantly higher than would be expected by chance (chi2=16.030, P=0.0001 and chi2=9.000, P=0.0001 respectively). Combination of techniques was also more frequent during invasive procedures and when dental anxiety levels were high. Combining techniques also tended to decrease dental anxiety more significantly than otherwise. Training has a role to play in the basic and efficient use in the management of the child dental patient. The training of dentists should thus entail the full spectrum (content and instructional effectiveness) of all psychological techniques. PMID:14969376

    Introduction: Venous hypertension (VH) is a distressing complication following the creation of arteriovenous fistula (AVF). The aim of management is to relieve edema with preservation of AVF. Extensive edema increases surgical morbidity with the loss of hemodialysis access. We present our experience in management of VH. Methods: A retrospective study was conducted on 37 patients with VH managed between July 2005 to May 2014. Patient demographics, evaluation, and procedures performed were noted. A successful outcome of management with surgical ligation (SL), angioembolization (AE), balloon dilatation (BD) or endovascular stent (EVS) was defined by immediate disappearance of thrill and murmur with resolution of edema in the next 48–72 h, no demonstrable flow during check angiogram and resolution of edema with preservation of AVF respectively. Results: All 8 distal AVF had peripheral venous stenosis and were managed with SL in 7 and BD in one patient. In 29 proximal AVF, central and peripheral venous stenosis was present in 16 and 13 patients respectively. SL, AE, BD, and BD with EVS were done in 18, 5, 4, and 3 patients, respectively. All patients had a successful outcome. SL was associated with wound related complications in 11 (29.73 %) patients. A total of 7 AVF were salvaged. One had restenosis after BD and was managed with AE. BD, EVS, and AE had no associated morbidity. Conclusions: Management of central and peripheral venous stenosis with VH should be individualized and in selected cases it seems preferable to secure a new access in another limb and close the native AVF in edematous limb for better overall outcome.

  18. Translocations of amphibians: Proven management method or experimental technique

    USGS Publications Warehouse

    Seigel, Richard A.; Dodd, C. Kenneth, Jr.

    2002-01-01

    In an otherwise excellent review of metapopulation dynamics in amphibians, Marsh and Trenham (2001) make the following provocative statements (emphasis added): If isolation effects occur primarily in highly disturbed habitats, species translocations may be necessary to promote local and regional population persistence. Because most amphibians lack parental care, they areprime candidates for egg and larval translocations. Indeed, translocations have already proven successful for several species of amphibians. Where populations are severely isolated, translocations into extinct subpopulations may be the best strategy to promote regional population persistence. We take issue with these statements for a number of reasons. First, the authors fail to cite much of the relevant literature on species translocations in general and for amphibians in particular. Second, to those unfamiliar with current research in amphibian conservation biology, these comments might suggest that translocations are a proven management method. This is not the case, at least in most instances where translocations have been evaluated for an appropriate period of time. Finally, the authors fail to point out some of the negative aspects of species translocation as a management method. We realize that Marsh and Trenham's paper was not concerned primarily with translocations. However, because Marsh and Trenham (2001) made specific recommendations for conservation planners and managers (many of whom are not herpetologists or may not be familiar with the pertinent literature on amphibians), we believe that it is essential to point out that not all amphibian biologists are as comfortable with translocations as these authors appear to be. We especially urge caution about advocating potentially unproven techniques without a thorough review of available options.

    Wound dehiscence is a serious postoperative complication, with an incidence of 0.5-3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of "intentional open abdomen" was described and both clinical entities share common pathophysiological and clinical pathways ("postoperative open abdominal wall"). Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as "frozen abdomen," where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the "Coliseum technique" for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of "malignant" frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    2013-01-01

    As chip power dissipation becomes a critical challenge in scaling processor performance, computer architects are forced to fundamentally rethink the design of modern processors and hence, the chip-design industry is now at a major inflection point in its hardware roadmap. The high leakage power and low density of SRAM poses serious obstacles in its use for designing large on-chip caches and for this reason, researchers are exploring non-volatile memory (NVM) devices, such as spin torque transfer RAM, phase change RAM and resistive RAM. However, since NVMs are not strictly superior to SRAM, effective architectural techniques are required for making them a universal memory solution. This book discusses techniques for designing processor caches using NVM devices. It presents algorithms and architectures for improving their energy efficiency, performance and lifetime. It also provides both qualitative and quantitative evaluation to help the reader gain insights and motivate them to explore further. This book will be highly useful for beginners as well as veterans in computer architecture, chip designers, product managers and technical marketing professionals.

  1. Random-access technique for modular bathymetry data storage in a continental shelf wave refraction program

    1974-01-01

    A study was conducted of an alternate method for storage and use of bathymetry data in the Langley Research Center and Virginia Institute of Marine Science mid-Atlantic continental-shelf wave-refraction computer program. The regional bathymetry array was divided into 105 indexed modules which can be read individually into memory in a nonsequential manner from a peripheral file using special random-access subroutines. In running a sample refraction case, a 75-percent decrease in program field length was achieved by using the random-access storage method in comparison with the conventional method of total regional array storage. This field-length decrease was accompanied by a comparative 5-percent increase in central processing time and a 477-percent increase in the number of operating-system calls. A comparative Langley Research Center computer system cost savings of 68 percent was achieved by using the random-access storage method.

    Ruszczyk, Chester Whitney, Alan

    Setting up experiments to utilize Experiment Guided Adaptive Endpoint (EGAE) and e-VLBI is presently a complex and time intensive process requiring scientific, Mark5 and networking knowledge. There is no central access to point to configure and manage all of these aspects of an experiment. The e-VLBI Access Point (eAXP) is a centralized control plane management tool that offers a GUI interface to augment the command line interface presently being used to set up and conduct experiments. eAXP contains three major toolsets: one to set up and execute an experiment using real-time or non-real time modes; the second to configure and manage EGAE; and a third to view statistics of the experiments. Initially the overall system architecture for eAXP is presented, followed by details of the Experiment Profiler toolset including screen shots of the system presently being tested. This will be followed by how eAXP will support real-time modes interfacing to the Dynamic Resource Allocation over GMPLS Optical Network (DRAGON) resource management project.

    As interest in the global change in temperatures and precipitation patterns grow, federal, state, and local agencies are turning to the delivery of 'actionable science and information' or 'information for decision-makers.' NOAA/National Centers for Environmental Information's Regional Climate Services program builds these bridges between the user of information and the producers of the information. With the Climate Data Records program, this study will present the extraction and use of the sea-surface temperature datasets specifically for access and use by fisheries managers in the north Atlantic. The work demonstrates the staged approach of accessing the records, converting their initial data formats into maps and charts, and the delivery of the data as a value-added information dashboard for use by managers. The questions to be reviewed include the ease of access, the delivery of open source software for visualizing the information, and a discussion on the roles of government and the private sector in the provision of climate information at different scales.

  9. A typology of intellectual property management for public health innovation and access: design considerations for policymakers.

    PubMed

    Taubman, Antony

    2010-01-01

    This paper seeks to set the practical discipline of public interest intellectual property (IP) management in public health into its broader policy context. The most immediate and direct impact of IP systems on public welfare results not from international standards nor from national legislation - though these norms are fundamentally important - but rather from the accumulated impact of numerous practical choices whether or not to seek IP protection; where and where not; and how any exclusive rights are deployed, by whom, and to what end. IP management is the essentially practical exercise of limited exclusive rights over protected subject matter, the judicious use of those rights to leverage outcomes that advance an institution's or a firm's objectives. Exclusive rights are used to construct and define knowledge-based relationships, to leverage access to technology and other necessary resources, and to enhance market-based incentives. IP management choices range across a broad spectrum, spanning public domain strategies, open or exclusive licensing, and strong exclusivity. The idea of 'exclusive rights', as a specific legal mechanism, can run counter to expectations of greater openness and accessibility, but actual outcomes will depend very much on how these mechanisms are used in practice. For public interest or public sector institutions concerned with health research and development, particularly the development of new medicines, IP management choices can be just as critical as they are for private firms, although a predominant institutional concentration on advancing direct public interest objectives may lead to significantly different approaches in weighing and exercising practical choices for IP management: even so, a private sector approach should not be conflated with exclusivity as an end in itself, nor need public interest IP management eschew all leverage over IP. This paper offers a tentative framework for a richer typology of those choices, to give a

  12. Resource reliability, accessibility and governance: pillars for managing water resources to achieve water security in Nepal

    NASA Astrophysics Data System (ADS)

    Biggs, E. M.; Duncan, J.; Atkinson, P.; Dash, J.

    2013-12-01

    As one of the world's most water-abundant countries, Nepal has plenty of water yet resources are both spatially and temporally unevenly distributed. With a population heavily engaged in subsistence farming, whereby livelihoods are entirely dependent on rain-fed agriculture, changes in freshwater resources can substantially impact upon survival. The two main sources of water in Nepal come from monsoon precipitation and glacial runoff. The former is essential for sustaining livelihoods where communities have little or no access to perennial water resources. Much of Nepal's population live in the southern Mid-Hills and Terai regions where dependency on the monsoon system is high and climate-environment interactions are intricate. Any fluctuations in precipitation can severely affect essential potable resources and food security. As the population continues to expand in Nepal, and pressures build on access to adequate and clean water resources, there is a need for institutions to cooperate and increase the effectiveness of water management policies. This research presents a framework detailing three fundamental pillars for managing water resources to achieve sustainable water security in Nepal. These are (i) resource reliability; (ii) adequate accessibility; and (iii) effective governance. Evidence is presented which indicates that water resources are adequate in Nepal to sustain the population. In addition, aspects of climate change are having less impact than previously perceived e.g. results from trend analysis of precipitation time-series indicate a decrease in monsoon extremes and interannual variation over the last half-century. However, accessibility to clean water resources and the potential for water storage is limiting the use of these resources. This issue is particularly prevalent given the heterogeneity in spatial and temporal distributions of water. Water governance is also ineffective due to government instability and a lack of continuity in policy

  13. Modern techniques and technologies for unbundled access in the local loop

    2015-02-01

    The efficient and unbundled use of the existing telecommunications infrastructure represents a major goal for the development of the services offered by telecommunications providers. A major telecommunications operator can provide services to a subscriber using a copper wire pair or part of the frequency spectrum of a copper wire pair, together with other operators, through a process of unbundling access in the local loop. Since access to the vocal band is an already solved problem, concerns turn to the broadband access with xDSL service delivery on ungrouped subscriber loops; besides the legal and economic aspects involved this has become an engineering problem also. The local loop unbundling methods have a substantial technical impact. This impact should be taken into account right from the design stage and then in the standardization stage of broadband systems intended to operate on copper wire pairs in the local loop. These systems are known under the generic term of xDSL and began to be analyzed in the late 90s. xDSL became the dominant solution for providing Internet at a reasonable price for both residential and business subscribers. In this massive development scenario, certain problems will arise from the early stages of deployment, and another type of problems will occur later on when a large number of systems will be installed in a single beam.

    Managing vast datasets collected throughout multiple clinical imaging communities has become critical with the ever increasing and diverse nature of datasets. Development of data management infrastructure is further complicated by technical and experimental advances that drive modifications to existing protocols and acquisition of new types of research data to be incorporated into existing data management systems. In this paper, an extensible data management system for clinical neuroimaging studies is introduced: The Human Clinical Imaging Database (HID) and Toolkit. The database schema is constructed to support the storage of new data types without changes to the underlying schema. The complex infrastructure allows management of experiment data, such as image protocol and behavioral task parameters, as well as subject-specific data, including demographics, clinical assessments, and behavioral task performance metrics. Of significant interest, embedded clinical data entry and management tools enhance both consistency of data reporting and automatic entry of data into the database. The Clinical Assessment Layout Manager (CALM) allows users to create on-line data entry forms for use within and across sites, through which data is pulled into the underlying database via the generic clinical assessment management engine (GAME). Importantly, the system is designed to operate in a distributed environment, serving both human users and client applications in a service-oriented manner. Querying capabilities use a built-in multi-database parallel query builder/result combiner, allowing web-accessible queries within and across multiple federated databases. The system along with its documentation is open-source and available from the Neuroimaging Informatics Tools and Resource Clearinghouse (NITRC) site. PMID:20567938

Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as “frozen abdomen,” where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the “Coliseum technique” for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of “malignant” frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    Giant cell granuloma (GCG) is an uncommon bony lesion in the head and neck region, most commonly affecting the maxilla and mandible and has a female predilection. The clinical behavior of central GCG ranges from a slowly growing asymptomatic swelling to an aggressive lesion. The clinical, radiological, histological features and management of an aggressive GCG of maxilla in an 18-year-old female patient are described and discussed. It is emphasized that surgery is the traditional and still the most accepted treatment for GCG. Le Fort I osteotomy has been advocated as one of the access osteotomy for the surgical management of aggressive and extensive GCG involving the maxilla. The postoperative morbidity and recurrence have been discussed. PMID:22754742

    The Hanford 300 Area Integrated Field Research Challenge is a multidisciplinary,multi institutional program funded by the Department of Energy - Office of Science. The objective of this program is to develop better models for uranium contamination in the 300 Area, a part of the Hanford site. This is achieved through a combination of large field scale experiments in a highly instrumented part of the 300 Area and accompanying laboratory studies and modeling and data analysis efforts. As part of the 300 Area IFRC large amounts of data are being generated - including but not limited to analysis data on over 1100 cores and samples obtained from the wellfield, geophysical and geological logs, time lapse electrical geophysical and temperature data, geochemical and hydrological data from observation wells and numerous model data. One of the challenges for the 300 Area IFRC is to ensure that all data generated as part of the IFRC is captured for analysis by the IFRC team and future scientists. In addition, tools are required facilitating the location, assessment and downloading of data. In order to meet this challenge a web accessible data management system was put in place. This system (which was built using Zend Framework, an open source, object-oriented web application framework) provides access to all data collected for the IFRC. Automated data harvesters keep the database up to date. Where available, the system uses standards for data models and access tools such that development requirements are minimized. By integrating the data access tools with Google Maps users can quickly locate different data sources. Data can be visualized on the fly in both graphs and animations (which are generated through webservice calls to JFreeChart). Through integration of the Zend Framework Structure with phpBB (Forum software) we provide a simple user management system which allows both forum discussions This system is stil being expanded. For instance, we are currently developing

  4. Immediate endodontic access cavity sealing: fundamentals of a new restorative technique.

    2015-09-01

    Endodontic access cavity sealing is conventionally performed after endodontic irrigation, referred to as delayed endodontic sealing (DES). Evidence shows that endodontic irrigation with NaOCl decreases dentinal bond quality and could cause coronal leakage. Access cavity sealing before endodontic irrigation is a new restorative approach, referred to as immediate endodontic sealing (IES). The primary aim of this in vitro study was to investigate whether IES improved internal adaptation. The secondary aim was to investigate the influence of the viscosity of the composite used to seal the dentine, on the internal adaptation in both IES and DES groups. Third molars (n= 40) with fully developed apices were used. The teeth were prepared into standard Class II MO cavities, and divided in 4 groups according to the approach, and composite viscosity was used for sealing. Group 1: IES + low viscosity composite; group 2: IES + high viscosity composite; group 3: DES + low viscosity composite; and group 4: DES + high viscosity composite. Samples were then sectioned axially for observation using scanning electron microscopy. Outcome was evaluated by determining the internal adaptation of the samples, which was judged based on the percentage of a continuous margin at the tooth-composite interface. The results were analyzed using a two-way analysis of variance and Mann-Whitney test. IES groups exhibited significantly greater internal adaptation (p = 0.000) as compared with DES groups. Composite viscosity did not significantly affect internal adaptation in either IES or DES groups (p > 0.005). PMID:25183493

    Advanced techniques for efficiently representing most forms of data are being implemented in practical hardware and software form through the joint efforts of three NASA centers. These techniques adapt to local statistical variations to continually provide near optimum code efficiency when representing data without error. Demonstrated in several earlier space applications, these techniques are the basis of initial NASA data compression standards specifications. Since the techniques clearly apply to most NASA science data, NASA invested in the development of both hardware and software implementations for general use. This investment includes high-speed single-chip very large scale integration (VLSI) coding and decoding modules as well as machine-transferrable software routines. The hardware chips were tested in the laboratory at data rates as high as 700 Mbits/s. A coding module's definition includes a predictive preprocessing stage and a powerful adaptive coding stage. The function of the preprocessor is to optimally process incoming data into a standard form data source that the second stage can handle.The built-in preprocessor of the VLSI coder chips is ideal for high-speed sampled data applications such as imaging and high-quality audio, but additionally, the second stage adaptive coder can be used separately with any source that can be externally preprocessed into the 'standard form'. This generic functionality assures that the applicability of these techniques and their recent high-speed implementations should be equally broad outside of NASA.

  7. Management of totally implantable vascular access devices in patients with cystic fibrosis.

    PubMed

    Dal Molin, A; Gatta, C; Festini, F

    2009-10-01

    Cystic fibrosis (CF) is a genetic disease associated with recurrent lung infections, that represent a major cause of mortality and morbidity. Cystic fibrosis requires frequent antibiotic treatments, sometimes by mouth or via aerosol but often via the intravenous route. Totally implanted venous access devices (ports) allow an easy and safe vascular access for unlimited periods of time, and they can be used in CF to administer antibiotics and other i.v. infusions; if compared to external central venous catheters, ports are better tolerated, since they permit almost unlimited physical activity and do not interfere with patient's self-image. Though ports require a minimal level of care, they may be sometimes associated with relevant complications, which can be insertion-related (pneumothorax, arterial puncture, local hematoma), or management-related (infection, occlusion of the lumen, venous thrombosis). This article summarizes some recommendations on the management of ports in CF, considering the existing literature. Still, some issues remain unsolved and will need further research and studies.

    2013-01-01

    The creation and maintenance of vascular access for hemodialysis patients is responsible for a significant amount of morbidity and hospital expenses which continue to escalate with increasing population of ESRD patients. A retrospective review of patient charts were performed from 2008 to May 2011 at an academic tertiary care center who had a diagnosis of vascular access failure based on ICD 9 coding. Data regarding demographic information, length of stay (LOS), source of insurance, hospital expenses, and discharge status were obtained. Based on strict inclusion criteria we identified 172 total patients. The mean age among all patients was 60.53 ± 15.35 years and the majority of patients were Hispanic (n = 81). The Mean LOS was 5.30 ± 4.64 days. Mean hospital costs were 41,896 ± 20,318 US$. Patients admitted for tunneled dialysis placement had greater length of stay (p-value = 0.011) as did patients with hypertension (p-value = 0.030). Hospital expenses were significantly higher for patients admitted for arterio-venous fistula complications (55,456 ± 23,779 US$) compared with admissions for catheter or dialysis graft related complications (p-value = 0.004). Patients on Medicare had significantly lower length of stay (3.98 ± 3.32 days) compared with patients with Medicare/Medical (6.59 ± 5.69 days), p-value = 0.047. Inpatient management of vascular access failure is associated with increased length of stay, and significant hospital expenses. Timely referral to vascular access centers can prevent unnecessary hospitalizations and provide cost-saving benefits. PMID:22686456

    1997-05-01

    Our objective is to offer clinicians wider access to evolving medical image processing (MIP) techniques, crucial to improve assessment and quantification of physiological processes, but difficult to handle for non-specialists in MIP. Based on artificial intelligence techniques, our approach consists in the development of a knowledge-based program supervision system, automating the management of MIP libraries. It comprises a library of programs, a knowledge base capturing the expertise about programs and data and a supervision engine. It selects, organizes and executes the appropriate MIP programs given a goal to achieve and a data set, with dynamic feedback based on the results obtained. It also advises users in the development of new procedures chaining MIP programs.. We have experimented the approach for an application of factor analysis of medical image sequences as a means of predicting the response of osteosarcoma to chemotherapy, with both MRI and NM dynamic image sequences. As a result our program supervision system frees clinical end-users from performing tasks outside their competence, permitting them to concentrate on clinical issues. Therefore our approach enables a better exploitation of possibilities offered by MIP and higher quality results, both in terms of robustness and reliability.

    2005-08-01

    This work aims to present a comprehensive study about the macroscopic characteristics of globular vegetable proteins, in terms of their gelling ability, by understanding their molecular behaviour, when submitted to a thermal gelling process. The gels of soy, pea and lupin proteins were characterized by rheological techniques. Gelation kinetics, mechanical spectra, as well as the texture of these gels were analyzed and compared. Additionally, capillary viscometry, steady-state fluorescence and fluorescence anisotropy were used to monitor the structural changes induced by the thermal denaturation, which constitutes the main condition for the formation of a gel structure. Based on these techniques it was possible to establish a relationship between the gelling ability of each protein isolate and their structural resistance to thermal unfolding, enabling us to explain the weakest and the strongest gelling ability observed for lupin and soy proteins isolates, respectively.

  13. Accessing Interior Vector Magnetic Field Components in Neutron EDM Experiments via Boundary Value Techniques

    NASA Astrophysics Data System (ADS)

    Plaster, Brad

    2012-10-01

    We propose a new technique for the determination and monitoring of the interior vector magnetic field components during the operation of neutron EDM experiments. If a suitable three-dimensional volume surrounding the fiducial volume of an experiment can be defined which contains no interior currents or magnetization, each of the interior vector field components will satisfy the Laplace Equation within this volume. Therefore, if the field components can be measured on the boundary, the interior vector field components can be determined uniquely via numerical solution of the Laplace Equation. We discuss the applicability of this technique to the determination of the magnetic field components and magnetic field gradients in the fiducial volumes of neutron EDM experiments.

    2016-03-01

    Decaying oscillations of the electric field in repetitive pulses of coherent synchrotron radiation in the terahertz frequency range was evaluated by means of time-resolving and correlation techniques. Comparative analysis of real-time voltage transients of the electrical response and interferograms, which were obtained with an ultrafast zero-bias Schottky diode detector and a Martin-Puplett interferometer, delivers close values of the pulse duration. Consistent results were obtained via the correlation technique with a pair of Golay Cell detectors and a pair of resonant polarisation-sensitive superconducting detectors integrated on one chip. The duration of terahertz synchrotron pulses does not closely correlate with the duration of single-cycle electric field expected for the varying size of electron bunches. We largely attribute the difference to the charge density oscillations in electron bunches and to the low-frequency spectral cut-off imposed by both the synchrotron beamline and the coupling optics of our detectors.

    1973-01-01

    A description is presented of a unique system for the sterilization and sterile repair of spacecraft and the results of a test program designed to assess the biological integrity and engineering reliability of the system. This trailer-mounted system, designated the model assembly sterilizer for testing (MAST), is capable of the dry-heat sterilization of spacecraft and/or components less than 2.3 meters in diameter at temperatures up to 433 K and the steam sterilization of components less than 0.724 meter in diameter. Sterile access to spacecraft is provided by two tunnel suits, called the bioisolator suit systems (BISS), which are contiguous with the walls of the sterilization chambers. The test program was designed primarily to verify the biological and engineering reliability of the MAST system by processing simulated space hardware. Each test cycle simulated the initial sterilization of a spacecraft, sterile repair of a failed component, removal of the spacecraft from the MAST for mating with the bus, and a sterile recycle repair.

    Urban Native Americans represent a small, diverse minority with unique health needs. The purposes of this descriptive retrospective study were to describe (a) the characteristics and primary health problems of urban Native Americans who receive primary health care at an urban nurse managed center (NMC) and (b) the nursing interventions provided at an urban NMC to urban Native Americans. A sample of 334 participants patient data were abstracted from a computerized clinical data set and coded based on the Omaha Classification System. The majority were over 40 years of age, were female, were single, completed high school, and were poor and uninsured, and many were unemployed. The most frequent health problems were related to pain, cardiovascular symptoms, dentition problems, and respiratory illnesses. The most frequent nursing interventions were for surveillance of physical signs and symptoms. The NMC was an accessible source of primary health care for urban Native Americans in northeastern Ohio.

    The aim of this study was to analyse high blood pressure detection, management, control and associated factors among residents accessing community health services (CHSs) in Beijing. We screened for HBP in 9524 individuals aged 50 years or older who accessed care in four Beijing CHSs. Among the 9397 residents with questionnaire responses that qualified them for inclusion in the study, 5029 patients with HBP were identified, 1510 (i.e., 30% of the HBP patient group) of whom were newly identified cases. The rate of hypertension detection was 53.5%. Among the 5029 HBP patients, the rates of awareness, treatment and control of hypertension were 70.0%, 62.1% and 29.6%, respectively. In general, the rate of hypertension control was higher when the rates of hypertension awareness and treatment were higher in subgroups stratified by different sociodemographic and risk factors, except for the overweight and obesity subgroups. In conclusion, suboptimal HBP awareness, treatment, and control are still major problems confronting CHSs in Beijing. Control of hypertension in the population may be improved by increasing awareness and improving the treatment of hypertension in CHSs. PMID:24784167

    For cosmetic consideration of parotidectomy, the surgical approaches have evolved from Blair incision through modified facelift incision to postaural-hairline incision. The present study aims at evaluating the feasibility and safety of the new technique of postaural approach. Parotidectomy was performed with a 4-5 cm incision in the postaural sulcus. There were 69 patients who were assessed pre-operatively feasible for consideration of the postaural parotidectomy. There were 56 (81 %) patients who could have the postaural parotidectomy successfully without complications. The minimally invasive postaural approach is a further step in cosmetic consideration of parotidectomy. It is a feasible and safe approach for most small to medium size benign parotid tumors located in the mid and lower pole regions of the parotid gland. PMID:26122398

    Evidence-based practice guidelines for interventional techniques in the management of chronic spinal pain are systematically developed and professionally derived statements and recommendations that assist both physicians and patients in making decisions about appropriate health care in the diagnosis and treatment of chronic or persistent pain. The guidelines were developed utilizing an evidence-based approach to increase patient access to treatment, to improve outcomes and appropriateness of care, and to optimize cost-effectiveness. All types of relevant and published evidence and consensus were utilized. The guidelines include a discussion of their purpose, rationale, and importance, including descriptions of the patient population served, the methodology, and the pathophysiologic basis for intervention. Multiple diagnostic and therapeutic interventional techniques are included in this document. Strong evidence was shown for diagnostic facet joint blocks for the diagnosis of facet joint pain, and lumbar provocative discography for discogenic pain. Moderate evidence was shown for sacroiliac joint blocks in the diagnosis of sacroiliac joint pain, and for transforaminal epidural injections in the preoperative evaluation of patients with negative or inconclusive imaging studies, but with clinical findings of nerve root irritation. Moderate to strong evidence was shown for multiple therapeutic interventional techniques including medial branch blocks and medial branch neurotomy; caudal epidural steroid injections and transforaminal epidural steroid injections; lumbar percutaneous adhesiolysis; and implantable therapies. These guidelines do not constitute inflexible treatment recommendations. It is expected that a provider will establish a plan of care on a case-by-case basis, taking into account an individual patient's medical condition, personal needs, and preferences, and the physician's experience. Based on an individual patient's needs, treatment different from that

    A critical challenge in measuring the power spectrum of 21 cm emission from cosmic reionization is compensating for the frequency dependence of an interferometer's sampling pattern, which can cause smooth-spectrum foregrounds to appear unsmooth and degrade the separation between foregrounds and the target signal. In this paper, we present an approach to foreground removal that explicitly accounts for this frequency dependence. We apply the delay transformation introduced in Parsons & Backer to each baseline of an interferometer to concentrate smooth-spectrum foregrounds within the bounds of the maximum geometric delays physically realizable on that baseline. By focusing on delay modes that correspond to image-domain regions beyond the horizon, we show that it is possible to avoid the bulk of smooth-spectrum foregrounds. We map the point-spread function of delay modes to k-space, showing that delay modes that are uncorrupted by foregrounds also represent samples of the three-dimensional power spectrum, and can be used to constrain cosmic reionization. Because it uses only spectral smoothness to differentiate foregrounds from the targeted 21 cm signature, this per-baseline analysis approach relies on spectrally and spatially smooth instrumental responses for foreground removal. For sufficient levels of instrumental smoothness relative to the brightness of interfering foregrounds, this technique substantially reduces the level of calibration previously thought necessary to detect 21 cm reionization. As a result, this approach places fewer constraints on antenna configuration within an array, and in particular, facilitates the adoption of configurations that are optimized for power-spectrum sensitivity. Under these assumptions, we demonstrate the potential for the Precision Array for Probing the Epoch of Reionization (PAPER) to detect 21 cm reionization at an amplitude of 10 mK2 near k ~ 0.2 h Mpc-1 with 132 dipoles in 7 months of observing.

    Objectives The objective is to present clinical outcomes of subglottic and tracheal stenosis treated by flexible bronchoscopic delivery of carbon dioxide (CO2) laser via laryngeal mask airway (LMA). Methods All consecutive, nontracheotomy dependent cases of subglottic and tracheal stenosis treated endoscopically over a 4-year period were retrospectively reviewed. The surgical approach consisted of radial incisions using a flexible fiber-based CO2 laser, balloon dilation, and topical application of mitomycin C. Ventilation during the procedure occurred through the LMA, and the CO2 laser fiber was delivered through the working channel of a flexible bronchoscope passed through the LMA. Number of dilations, period between dilations, and operative times were reviewed. Results Eleven patients who underwent airway intervention during the study period were identified. Average follow-up was 28 months. Etiologies of airway stenosis included intubation injury (6), idiopathic (4), or autoimmune disease (1), requiring an average of 1.3, 1.5, and 3 dilations, respectively. Average operative time was 67 minutes. Autoimmune etiology correlated with more frequent dilations. Conclusion LMA is an effective way to manage ventilation while simultaneously allowing unencumbered flexible bronchoscopic access for laser surgery, balloon dilation, and mitomycin C application for airway stenosis. Long-term success in treating stenosis is achievable using this technique. PMID:24671485

    2014-09-01

    Initially introduced as special-purpose accelerators for graphics applications, graphics processing units (GPUs) have now emerged as general purpose computing platforms for a wide range of applications. To address the requirements of these applications, modern GPUs include sizable hardware-managed caches. However, several factors, such as unique architecture of GPU, rise of CPU–GPU heterogeneous computing, etc., demand effective management of caches to achieve high performance and energy efficiency. Recently, several techniques have been proposed for this purpose. In this paper, we survey several architectural and system-level techniques proposed for managing and leveraging GPU caches. We also discuss the importance and challenges of cache management in GPUs. The aim of this paper is to provide the readers insights into cache management techniques for GPUs and motivate them to propose even better techniques for leveraging the full potential of caches in the GPUs of tomorrow.

  1. Efficient Consistency Achievement of Federated Identity and Access Management Based on a Novel Self-Adaptable Approach

    NASA Astrophysics Data System (ADS)

    Cha, Shi-Cho; Chang, Hsiang-Meng

    Federated identity and access management (FIAM) systems enable a user to access services provided by various organizations seamlessly. In FIAM systems, service providers normally stipulate that their users show assertions issued by allied parties to use their services as well as determine user privileges based on attributes in the assertions. However, the integrity of the attributes is important under certain circumstances. In such a circumstance, all released assertions should reflect modifications made to user attributes. Despite the ability to adopt conventional certification revocation technologies, including CRL or OCSP, to revoke an assertion and request the corresponding user to obtain a new assertion, re-issuing an entirely new assertion if only one attribute, such as user location or other environmental information, is changed would be inefficient. Therefore, this work presents a self-adaptive framework to achieve consistency in federated identity and access management systems (SAFIAM). In SAFIAM, an identity provider (IdP), which authenticates users and provides user attributes, should monitor access probabilities according to user attributes. The IdP can then adopt the most efficient means of ensuring data integrity of attributes based on related access probabilities. While Internet-based services emerge daily that have various access probabilities with respect to their user attributes, the proposed self-adaptive framework significantly contributes to efforts to streamline the use of FIAM systems.

    are of acceptably high quality. The formats and data structures used by the seismological community are esoteric. IRIS and its FDSN partners are developing web services that can transform the data holdings to structures that are more easily used by broader scientific communities. For instance, atmospheric scientists are interested in using global observations of microbarograph data but that community does not understand the methods of applying instrument corrections to the observations. Web processing services under development at IRIS will transform these data in a manner that allows direct use within such analysis tools as MATLAB® already in use by that community. By continuing to develop web-service based methods of data discovery and access, IRIS is enabling broader access to its data holdings. We currently support data discovery using many of the Open Geospatial Consortium (OGC) web mapping services. We are involved in portal technologies to support data discovery and distribution for all data from the EarthScope project. We are working with computer scientists at several universities including the University of Washington as part of a DataNet proposal and we intend to enhance metadata, further develop ontologies, develop a Registry Service to aid in the discovery of data sets and services, and in general improve the semantic interoperability of the data managed at the IRIS DMC. Finally IRIS has been identified as one of four scientific organizations that the External Research Division of Microsoft wants to work with in the development of web services and specifically with the development of a scientific workflow engine. More specific details of current and future developments at the IRIS DMC will be included in this presentation.

    To maintain high availability of nuclear generating units is one of the most important management objectives. The duration of outages-whether planned or unplanned-is the main parameter impacting on plant availability, but the planned outages, and essentially the refueling outages, are the most important in this respect, and they also have a heavy impact on the economics of plant operation. The following factors influence the duration of the outages: (1) modifications; (2) preventive maintenance operations; and (3) corrective maintenance operations of generic faults. In this paper, the authors examine how the outage management organization of Electricite de France (EdF) plants is tending to optimize the solutions to the above-mentioned points.

    The basic approach in the automated power system management (APSM) implementation is to use one central microprocessor for the overall power system supervision and several local microprocessors dedicated to one or more major subassemblies to perform simple monitoring and control functions. Communication between the central and each local processor is through a dedicated two-wire network employing serial data transfer. The block diagrams of the processors, the data bus characteristics, and the software functions and organization are presented.

    In this study, a new method for terminating second trimester pregnancies complicated by intrauterine fetal death is analysed. The technique consisted of a combination of extraamniotic ethacridine lactate with intramuscular sulprostone (16-phenoxy-omega-17,18,19,20 tetranor PGE2 methyl sulfonylamide). Objective documentation of the efficacy of this method was obtained by continuous monitoring of intrauterine pressure in two patients. The method was found to be simple, safe, cheap and effective and deserves increased acceptance. PMID:2564363

    2015-05-01

    In 2012, the Czech Republic established the women's age limit for access to assisted reproduction techniques at age 49 years. In this paper, the acceptability of this age limit from the children's perspective in the Czech Republic is assessed. Although the necessity of balancing the interests of parents and children is acknowledged, little research has taken children's interests into account. We have attempted to map out 'children's interests', asking older children and adolescents (aged 11-25 years) how old they would prefer their parents to be: Czech respondents would prefer to have younger parents. This finding is consistent with the optimal biological childbearing age rather than with the current postponement to a later age. So far, assisted reproduction techniques have been largely regarded as a medical treatment justifying the current women's age limit of 49 years. Had the children's perspective been taken into account, this age limit might have been lower than 49 years. We propose that reproductive health policy should adequately reflect multiple perspectives as an integral part of a multi-layered support system of a society. PMID:25773530

  18. WOVOdat: A New Tool for Managing and Accessing Data of Worldwide Volcanic Unrest

    NASA Astrophysics Data System (ADS)

    2002-12-01

    WOVOdat (World Organization of Volcano Observatories database of volcanic unrest) will for the first time bring together data of worldwide volcanic seismicity, ground deformation, fumarolic activity, and other changes within or adjacent to a volcanic system. Although a large body of data and experience has been built over the past century, currently, we have no means of accessing that collective experience for use during crises and for research. WOVOdat will be the central resource of a data management system; other components will include utilities for data input and archiving, structured data retrieval, and data mining; educational modules; and links to institutional databases such as IRIS (global seismicity), UNAVCO (global GPS coordinates and strain vectors), and Smithsonian's Global Volcanism Program (historical eruptions). Data will be geospatially and time-referenced, to provide four dimensional images of how volcanic systems respond to magma intrusion, regional strain, and other disturbances prior to and during eruption. As part of the design phase, a small WOVOdat team is currently collecting information from observatories about their data types, formats, and local data management. The database schema is being designed such that responses to common, yet complex, queries are rapid (e.g., where else has similar unrest occurred and what was the outcome?) while also allowing for more detailed research analysis of relationships between various parameters (e.g., what do temporal relations between long-period earthquakes, transient deformation, and spikes in gas emission tell us about the geometry and physical properties of magma and a volcanic edifice?). We are excited by the potential of WOVOdat, and we invite participation in its design and development. Next steps involve formalizing and testing the design, and, developing utilities for translating data of various formats into common formats. The large job of populating the database will follow, and eventually

  19. Techniques for early diagnosis and management of cervicofacial necrotising fasciitis

    Lee, Judy W; Immerman, Sara B; Morris, Luc GT

    2010-01-01

    Background Cervicofacial necrotising fasciitis carries high rates of morbidity and mortality, and is not often initially suspected due to its rarity and misleadingly innocuous presentation. We propose an algorithm for the timely diagnosis and management of cervicofacial necrotising fasciitis. Methods Retrospective review of seven patients ultimately diagnosed with cervicofacial necrotising fasciitis. Results In these seven patients, common presenting symptoms included sore throat, fever and neck pain. On initial examination and imaging, only three had obvious findings. One patient’s diagnosis was facilitated via a bedside cut-down procedure. Six patients underwent surgical debridement. Four required tracheotomy, and five wounds closed via secondary intention. There were two deaths. Conclusion The severity of cervical necrotising fasciitis and its rapid spread necessitate early diagnosis and timely surgical management. The presentation often appears benign. A high index of clinical suspicion should be maintained in cases of neck cellulitis with nonspecific clinical findings, especially in diabetic or otherwise immunocompromised patients. A normal computed tomography scan does not rule out necrotising fasciitis. A cut-down procedure may be critical to early diagnosis in some cases. PMID:20298644

    1999-01-01

    Twenty-four patients with painful restricted motion of the elbow joint because of an arthritic process were treated with an arthroscopic modification of the open Outerbridge-Kashiwagi procedure. Average preoperative flexion was to 90 degrees (range 60 degrees to 140 degrees), and average extension loss was -40 degrees (range -5 degrees to -60 degrees). The average total arc of motion was 50 degrees. The procedure consisted of arthroscopic debridement, partial resection of the coronoid and olecranon processes, and fenestration of the olecranon fossa. The radial head was excised arthroscopically in 18 of the 24 patients. All patients were reexamined 24 to 60 months after operation (mean 32 months). All patients had a significant decrease in pain as described by a visual analog scale (preoperative 8.2; postoperative 2.2). Average flexion was to 139 degrees (range 95 degrees to 145 degrees), and average extension loss was -8 degrees (range 0 degree to 15 degrees). The average arc of motion was 131 degrees, an improvement of 81 degrees. Arthroscopic ulnohumeral arthroplasty provides satisfactory results in terms of pain control and improved motion. The complication rate is comparable to those reported in series of open ulnohumeral arthroplasties. This procedure seems to be a valuable adjunct in the management of the arthritic elbow, serving as an intermediate step between nonoperative management and elbow replacement surgery. PMID:10389075

    The measurement of various parameters--be it plain temperature readings or determination of pesticides, drug monitoring or measurement of contaminants in air or water--must be carried out precisely and accurately. After purchase of the instrument, the installation qualification and the operation qualification, both produced by experts in the manufacturing company, are used to ensure correct use of the instrument. The standard operating procedures for instrument management must be sufficiently detailed to allow the operator to use the instrument correctly and, above all, must contain all the information necessary for accurate and precise calibrations. From 2002, the Food and Drug Administration will no longer accept submission of paper dossiers, so that pharmaceutical companies wishing to register a product in the USA will be obliged to submit the dossier electronically. This will involve the validation of all the software used in the management and operation of all instruments. It can be assumed that the EMEA will shortly follow the FDA, so that the validation of instrument software systems will become the rule and create new responsibilities for operators and inspectors.

    2014-01-01

    Background Phylogenetic tools and ‘tree-thinking’ approaches increasingly permeate all biological research. At the same time, phylogenetic data sets are expanding at breakneck pace, facilitated by increasingly economical sequencing technologies. Therefore, there is an urgent need for accessible, modular, and sharable tools for phylogenetic analysis. Results We developed a suite of wrappers for new and existing phylogenetics tools for the Galaxy workflow management system that we call Osiris. Osiris and Galaxy provide a sharable, standardized, modular user interface, and the ability to easily create complex workflows using a graphical interface. Osiris enables all aspects of phylogenetic analysis within Galaxy, including de novo assembly of high throughput sequencing reads, ortholog identification, multiple sequence alignment, concatenation, phylogenetic tree estimation, and post-tree comparative analysis. The open source files are available on in the Bitbucket public repository and many of the tools are demonstrated on a public web server (http://galaxy-dev.cnsi.ucsb.edu/osiris/). Conclusions Osiris can serve as a foundation for other phylogenomic and phylogenetic tool development within the Galaxy platform. PMID:24990571

    With advancement of medical interventions, the lifespan of people living with HIV has increased globally. However, low- and middle-income countries (LMICs) which bear the greatest burden of the HIV pandemic face a constant challenge in addressing the treatment needs of immune-suppressed patients. An analysis of the current management protocols and access to medication in resource-poor settings was conducted at this workshop, with emphasis on the situation in resource-poor settings. The participants developed a consensus document based on the need to respond to the constantly changing HIV pandemic. Provision of oral health care must be guided by interconnecting principles based on population based strategies that address upstream determinants of health. Basic oral health coverage in developing countries can only be realized with a strong foundation at the primary health level. Early diagnosis of HIV-related comorbidities including the adverse effects of ARVs is essential for the improvement of treatment outcomes. Standardization of oral health care delivery mechanisms will facilitate evaluation at national and regional levels. Oral health care workers have a moral obligation to participate in sustained campaigns to reduce the social stigma associated with HIV/AIDS in their work places at every stage of the referral chain. Future research also needs to realign itself towards prevention using the common risk factor approach, which has a broader impact on non-communicable diseases, which are increasingly affecting patients with HIV/AIDS as their life expectancies increase.

    2006-01-01

    Elbow contracture may be caused by intrinsic or extrinsic limitations or a combination of both. Evaluation of the specific structures guides the development of an effective therapy treatment program. Intrinsic contractures are by definition due to joint/intra-articular incongruency, and therefore therapy and splinting cannot provide increase in joint motion. Nonoperative therapy treatment options include heat modalities, myofascial soft tissue mobilization, joint mobilization, muscle energy techniques, passive range of motion, active range of motion, extensive use of corrective splinting, and strengthening exercise. All operative candidates must participate in a preoperative therapy program of six to eight weeks to reduce extrinsic contractures as feasible and to assess patient compliance with an intensive postoperative therapy program. Corrective splinting may be needed for as long as six months to maintain gains made in surgery. The therapy following manipulation under anesthesia and open contracture release is similar. The therapist must know the details of the procedure. Operative treatment for the stiff elbow progresses in a sequential fashion to progressively release tissue structures limiting motion and reconstruct any structures as needed to provide joint stability. Postoperative therapy consists of continuous passive motion , corrective splinting, modalities, and specific exercise techniques to maintain passive gains achieved in surgery. The therapy is extensive and requires full participation from the patient to maximize motion and function. Complications of elbow contracture release include nerve palsy or nerve injury, seroma, joint instability, heterotopic ossification, and recurrence of elbow contracture. PMID:16713873

    Unfavorable outcomes such as facial paralysis and deafness were once unfortunate probable complications following resection of acoustic neuromas. However, the implementation of intraoperative neuromonitoring during acoustic neuroma surgery has demonstrated placing more emphasis on quality of life and preserving neurological function. A modern review demonstrates a great degree of recent success in this regard. In facial nerve monitoring, the use of modern electromyography along with improvements in microneurosurgery has significantly improved preservation. Recent studies have evaluated the use of video monitoring as an adjunctive tool to further improve outcomes for patients undergoing surgery. Vestibulocochlear nerve monitoring has also been extensively studied, with the most popular techniques including brainstem auditory evoked potential monitoring, electrocochleography, and direct compound nerve action potential monitoring. Among them, direct recording remains the most promising and preferred monitoring method for functional acoustic preservation. However, when compared with postoperative facial nerve function, the hearing preservation is only maintained at a lower rate. Here, the authors analyze the major intraoperative neuromonitoring techniques available for acoustic neuroma resection. PMID:22937857

  7. Arthroscopic management of tibial plateau fractures: special techniques.

    PubMed

    Perez Carro, L

    1997-04-01

    Arthroscopic assessment and treatment of tibial plateau fractures has gained popularity in recent years. This article describes some maneuvers to facilitate the management of these fractures with the arthroscope. We use a 14-mm rounded curved periosteal elevator to manipulate fragments within the joint instead of using a probe. To facilitate visualization of fractures, we describe the use of loop sutures around the meniscus to retract the meniscus when there is a tear in the meniscus. We suggest the use of the arthroscope for directly viewing the interosseous space to be sure that any internal fixation devices remain outside the articular space. The use of these tactics will allow a faster, more accurate reduction with less radiation exposure in patients with displaced tibial plateau fractures. PMID:9127091

    Tests were performed to evaluate three different methods of utilizing air to provide thermal management control for compliant journal foil air bearings. The effectiveness of the methods was based on bearing bulk temperature and axial thermal gradient reductions during air delivery. The first method utilized direct impingement of air on the inner surface of a hollow test journal during operation. The second, less indirect method achieved heat removal by blowing air inside the test journal to simulate air flowing axially through a hollow, rotating shaft. The third method emulated the most common approach to removing heat by forcing air axially through the bearing s support structure. Internal bearing temperatures were measured with three, type K thermocouples embedded in the bearing that measured general internal temperatures and axial thermal gradients. Testing was performed in a 1 atm, 260 C ambient environment with the bearing operating at 60 krpm and supporting a load of 222 N. Air volumetric flows of 0.06, 0.11, and 0.17 cubic meters per minute at approximately 150 to 200 C were used. The tests indicate that all three methods provide thermal management but at different levels of effectiveness. Axial cooling of the bearing support structure had a greater effect on bulk temperature for each air flow and demonstrated that the thermal gradients could be influenced by the directionality of the air flow. Direct air impingement on the journal's inside surface provided uniform reductions in both bulk temperature and thermal gradients. Similar to the direct method, indirect journal cooling had a uniform cooling effect on both bulk temperatures and thermal gradients but was the least effective of the three methods.

    Management of obesity should initially involve assessment of the pet to rule out other possible medical problems and provide an accurate dietary history. It is essential to obtain a good estimate of the existing caloric intake, including calories from table scraps, pet treats, or other sources. Assessing the owner's willingness to make a commitment to a major lifestyle change for their pet is also an important part of any successful weight-reduction program. In some instances, this motivation can be linked to a recent, expensive bill for orthopedic or other procedures performed on their pet. Once a candidate has entered a program, calculated restriction of energy while maintaining protein, vitamin, and mineral intake should be recommended. It may be surprising to find out that the calculated amounts of food may be more than the amount a pet is currently being fed. In these animals, it is imperative to use a high-protein, obesity-management diet and not a low-protein, "light," or senior type of diet containing high fiber. If possible, treats should be restricted altogether and begging actively discouraged. Any snacks should be placed in the pet's feeding bowl so that an association between eating and the bowel become established. Of equal importance is use of a realistic exercise program that owners will encourage their pet to follow. Various products for weight reduction are available. Use of these specially formulated products to restrict caloric intake, while maintaining essential nutrient intake and increasing energy expenditure by playing and other activities, are the hallmarks of successful weight loss programs.

    Carotid endarterectomy (CEA) is a common and efficacious surgical procedure for the prevention of ischemic stroke due to atherosclerosis of the internal carotid artery (ICA). A high common carotid artery bifurcation can make CEA technically difficult due to limited carotid artery exposure. A cadaveric study was performed to evaluate the efficacy of nasotracheal intubation for improving access to a high carotid artery bifurcation. Based on this study, nasotracheal intubation does not improve access to a high carotid artery bifurcation as compared with orotracheal intubation. PMID:26312946

    Introduction The contemporary parents are more active and participate in the decision making during dental treatment. Aim To assess the parents’ acceptance towards behavior management techniques commonly used in the pediatric dentistry in different dental situation. Materials and Methods Fifty-one parents participated in the study. Children’s dental fear was assessed by the parents before attending power point presentation using Dental Subscale of the Children’s Fear Survey Schedule (CFSS-DS). Parents viewed power point presentation of eight behavior management techniques being used during pediatric dental treatment. The techniques were: 1) Voice control; 2) Tell-Show-Do; 3) Positive reinforcement; 4) Parental presence or absence; 5) HOME; 6) Physical restraint; 7) N2O-O2 sedation; 8) General anesthesia. Parents were asked to arrange various behavior management techniques from most accepted technique to least accepted technique in various dental situations according to their view. Results All the parents completed the questionnaire. Most children show increased anxiety related to dental component of CFSS-DS scale particularly during the administration of local anesthetic. In present study most preferred behavior management technique was Tell-Show-Do followed by positive reinforcement and least preferred behavior management technique was general anesthesia followed by physical restraint. Conclusion Children’s anxiety level increases during the condition related to dentistry which can be overcome by developing positive approach in children and parents towards dentistry and by utilizing various behaviour management strategies. A generalized low parental tolerance level for firm management techniques was seen in the present study population.

    The Risk Management System collects information from engineering, operating, and management personnel to identify potentially hazardous conditions. This information is used in risk analysis, problem resolution, and contingency planning. The resulting hazard accountability system enables management to monitor all identified hazards. Data from this system are examined in project reviews so that management can decide to eliminate or accept these risks. This technique is particularly effective in improving the management of risks in large, complex, high-energy facilities. These improvements are needed for increased cooperation among industry, regulatory agencies, and the public.

  20. Flow management techniques for base and afterbody drag reduction

    NASA Astrophysics Data System (ADS)

    Viswanath, P. R.

    The problem of turbulent base flows and the drag associated with it have been of significant interest in missile as well as fighter aircraft design. Numerous studies in the literature have been devoted to aspects of reducing base drag on two-dimensional as well as on axisymmetric bodies. This paper presents a review of the developments that have taken place on the use of passive techniques or devices for axisymmetric base and net afterbody drag reduction in the absence of jet flow at the base. In particular, the paper discusses the effectiveness of base cavities, ventilated cavities, locked vortex afterbodies, multi-step afterbodies and afterbodies employing a non-axisymmetric boat-tailing concept for base and net drag reduction in different speed regimes. The broad features of the flow and the likely fluid-dynamical mechanisms associated with the device leading to base drag reduction are highlighted. Flight-test results assessing the effectiveness of some of the devices are compared with data from wind tunnels. The present survey indicates that base and net afterbody drag reduction of considerable engineering significance in aerospace applications can be achieved by various passive devices even when the (unmanipulated) base flow is not characterised by vortex shedding.

    Fire is widely recognized as a critical ecological and evolutionary driver that needs to be at the forefront of land management actions if conservation targets are to be met. However, the prevailing view is that prescribed fire is riskier than other land management techniques. Perceived risks associated with the application of fire limits its use and reduces agency support for prescribed burning in the private sector. As a result, considerably less cost-share support is given for prescribed fire compared to mechanical techniques. This study tests the general perception that fire is a riskier technique relative to other land management options. Due to the lack of data available to directly test this notion, we use a combination of approaches including 1) a comparison of fatalities resulting from different occupations that are proxies for techniques employed in land management, 2) a comparison of fatalities resulting from wildland fire versus prescribed fire, and 3) an exploration of causal factors responsible for wildland fire-related fatalities. This approach establishes a first approximation of the relative risk of fatality to private citizens using prescribed fire compared to other management techniques that are readily used in ecosystem management. Our data do not support using risks of landowner fatalities as justification for the use of alternative land management techniques, such as mechanical (machine-related) equipment, over prescribed fire. Vehicles and heavy machinery are consistently leading reasons for fatalities within occupations selected as proxies for management techniques employed by ranchers and agricultural producers, and also constitute a large proportion of fatalities among firefighters. Our study provides the foundation for agencies to establish data-driven decisions regarding the degree of support they provide for prescribed burning on private lands. PMID:26465329

    Several surgical alternatives have been described for the management of cecal impaction in the horse, but none has met with consistently successful results. This study was done to evaluate a surgical bypass of the cecum by anastomosis of the ileum to the right ventral colon (ileocolostomy). A ventral midline celiotomy was performed on nine adult ponies (155-350 kg) and a mechanically stapled 10 cm side-to-side ileocolostomy was created. In five ponies a complete cecal bypass (CCB) was created by transecting the ileum distal to the anastomosis. In the other four, an incomplete cecal bypass (ICB) was created with no interruption of the ileum. Six horses with clinical cecal impaction also underwent cecal bypass procedures. Five had a CCB and one had an ICB. All the ponies maintained body weight, had no change in consistency of the feces and had no abdominal pain during the 6 month observation period. At necropsy, the lengths of the lateral cecal band, lateral free band of the colon, and the diameter of the anastomotic stoma were compared to measurements made at surgery. The lateral cecal band length decreased significantly more in the CCB ponies than in the ICB ponies (p = 0.008). The anastomotic stoma diameter was significantly larger in the ICB group than in the CCB group (p = 0.032). Five of the six clinical cases recovered and returned to their previous activity. CCB by an ileocolostomy resulted in removal of the cecum from the functional flow of ingesta without complication in the ponies, and was successful in five clinical cases of cecal impaction.

    A challenge for many clinical users is that a patient may receive a diagnostic imaging (DI) service at a number of hospitals or private imaging clinics. The DI services that patients receive at other locations could be clinically relevant to current treatments, but typically, there is no seamless method for a clinical user to access longitudinal DI results for their patient. Radiologists, and other specialists that are intensive users of image data, require seamless ingestion of foreign exams into the picture archiving and communication system (PACS) to achieve full clinical value. Most commonly, a clinical user will depend on the patient to bring in a CD that contains imaging from another location. However, a number of issues can arise when using this type of solution. Firstly, a CD will not provide the clinical user with the full longitudinal record of the patient. Secondly, a CD often will not contain the report associated with the images. Finally, a CD is not seamless, due to the need to manually import the contents of the CD into the local PACS. In order to overcome these limitations, and provide clinical users with a greater benefit related to a patient's longitudinal DI history, the implementation of foreign exam management (FEM) at the local site level is required. This paper presents the experiences of FEM in practice. By leveraging industry standards and edge devices to support FEM, multiple sites with disparate PACS and radiology information system (RIS) vendors are able to seamlessly ingest foreign exams within their local PACS as if they are local exams.

    There is no shortage of community-specific and generic data discovery and download platforms and protocols (e.g. CUAHSI HIS, DataONE, GeoNetwork Open Source, GeoPortal, OGC CSW, OAI PMH), documentation standards (e.g. FGDC, ISO 19115, EML, Dublin Core), data access and visualization standards and models (e.g. OGC WxS, OpenDAP), and general-purpose web service models (i.e. REST & SOAP) upon which Geo-informatics cyberinfrastructure (CI) may be built. When attempting to develop a robust platform that may service a wide variety of users and use cases the challenge is one of identifying which existing platform (if any) may support those current needs while also allowing for future expansion for additional capabilities. In the case of the implementation of a data storage, discovery and delivery platform to support the multiple projects at the Earth Data Analysis Center at UNM, no single platform or protocol met the joint requirements of two initial applications (the New Mexico Resource Geographic Information System [http://rgis.unm.edu] and the New Mexico EPSCoR Data Portal [http://nmepscor.org/dataportal]) and furthermore none met anticipated additional requirements as new applications of the platform emerged. As a result of this assessment three years ago EDAC embarked on the development of the Geographic Storage, Transformation, and Retrieval Engine (GSToRE) platform as a general purpose platform upon which n-tiered geospatially enabled data intensive applications could be built. When initially released in 2010 the focus was on the publication of dynamically generated Open Geospatial Consortium services based upon a PostgreSQL/PostGIS backend database. The identification of additional service interface requirements (implementation of the DataONE API and CUAHSI WaterML services), use cases provided by the NM EPSCoR education working group, and expanded metadata publication needs have led to a significant update to the underlying data management tier for GSToRE - the

    To manage posterior capsule rupture during phacoemulsification, we use a dry technique in which all procedures are performed without an irrigation/aspiration system. The dry technique is characterized by (1) continuous viscoelastic injection instead of fluid irrigation to maintain anterior chamber depth with the posterior capsule and vitreous located posteriorly and (2) static removal of most residual lens material by viscoexpression and/or manual small incision extracapsular cataract extraction without aspiration and dynamic water flow. In 16 cases of posterior capsule rupture managed using the dry technique, the residual nucleus and cortex were readily removed with minimum extension of the ruptured area and new vitreous loss. Although large amounts of viscoelastic material (mean 5.8 mL) were required, rapid and stable visual recovery was comparable to that in patients having uneventful surgery. The dry system is a safe and reliable technique for managing posterior capsule rupture during phacoemulsification. PMID:11489564

    Purpose: To evaluate the safety and feasibility of percutaneous transsplenic access to the portal vein for management of vascular complication in patients with chronic liver diseases. Methods: Between Sept 2009 and April 2011, percutaneous transsplenic access to the portal vein was attempted in nine patients with chronic liver disease. Splenic vein puncture was performed under ultrasonographic guidance with a Chiba needle, followed by introduction of a 4 to 9F sheath. Four patients with hematemesis or hematochezia underwent variceal embolization. Another two patients underwent portosystemic shunt embolization in order to improve portal venous blood flow. Portal vein recanalization was attempted in three patients with a transplanted liver. The percutaneous transsplenic access site was closed using coils and glue. Results: Percutaneous transsplenic splenic vein catheterization was performed successfully in all patients. Gastric or jejunal varix embolization with glue and lipiodol mixture was performed successfully in four patients. In two patients with a massive portosystemic shunt, embolization of the shunting vessel with a vascular plug, microcoils, glue, and lipiodol mixture was achieved successfully. Portal vein recanalization was attempted in three patients with a transplanted liver; however, only one patient was treated successfully. Complete closure of the percutaneous transsplenic tract was achieved using coils and glue without bleeding complication in all patients. Conclusion: Percutaneous transsplenic access to the portal vein can be an alternative route for portography and further endovascular management in patients for whom conventional approaches are difficult or impossible.

    Mercury is a federated metadata harvesting, data discovery and access tool based on both open source packages and custom developed software. Though originally developed for NASA, the Mercury development consortium now includes funding from NASA, USGS, and DOE. Mercury supports the reuse of metadata by enabling searching across a range of metadata specification and standards including XML, Z39.50, FGDC, Dublin-Core, Darwin-Core, EML, and ISO-19115. Mercury provides a single portal to information contained in distributed data management systems. It collects metadata and key data from contributing project servers distributed around the world and builds a centralized index. The Mercury search interfaces then allow the users to perform simple, fielded, spatial and temporal searches across these metadata sources. One of the major goals of the recent redesign of Mercury was to improve the software reusability across the 12 projects which currently fund the continuing development of Mercury. These projects span a range of land, atmosphere, and ocean ecological communities and have a number of common needs for metadata searches, but they also have a number of needs specific to one or a few projects. To balance these common and project-specific needs, Mercury's architecture has three major reusable components; a harvester engine, an indexing system and a user interface component. The harvester engine is responsible for harvesting metadata records from various distributed servers around the USA and around the world. The harvester software was packaged in such a way that all the Mercury projects will use the same harvester scripts but each project will be driven by a set of project specific configuration files. The harvested files are structured metadata records that are indexed against the search library API consistently, so that it can render various search capabilities such as simple, fielded, spatial and temporal. This backend component is supported by a very flexible

    : This study aims to describe a new technique for the management of auricular hematoma using fibrin glue. Five difficult cases of auricular hematoma were managed using this technique, including 2 recurrent and 3 delayed presentations. After skin preparation and local anesthetic, an incision was made, the hematoma was evacuated, and the cavity was washed out with saline. Fibrin glue was applied liberally; a dental roll pressure dressing was applied and secured with a prolene bead suture. The patients were given a course of oral antibiotic and reviewed after 5 days for removal of the external dressing. They were later assessed to exclude re-accumulation of the hematoma. All patients had complete resolution of the hematoma without re-accumulation; they were satisfied with the cosmetic results and experienced no complications. This case series provides evidence that fibrin glue is effective in the management of auricular hematoma. Larger studies may provide further evidence of the effectiveness of this new technique.

    2009-04-01

    SeaDataNet is an Integrated research Infrastructure Initiative (I3) in EU FP6 (2006 - 2011) to provide the data management system adapted both to the fragmented observation system and the users need for an integrated access to data, meta-data, products and services. Therefore SeaDataNet insures the long term archiving of the large number of multidisciplinary data (i.e. temperature, salinity current, sea level, chemical, physical and biological properties) collected by many different sensors installed on board of research vessels, satellite and the various platforms of the marine observing system. The SeaDataNet project started in 2006, but builds upon earlier data management infrastructure projects, undertaken over a period of 20 years by an expanding network of oceanographic data centres from the countries around all European seas. Its predecessor project Sea-Search had a strict focus on metadata. SeaDataNet maintains significant interest in the further development of the metadata infrastructure, but its primary objective is the provision of easy data access and generic data products. SeaDataNet is a distributed infrastructure that provides transnational access to marine data, meta-data, products and services through 40 interconnected Trans National Data Access Platforms (TAP) from 35 countries around the Black Sea, Mediterranean, North East Atlantic, North Sea, Baltic and Arctic regions. These include: National Oceanographic Data Centres (NODC's) Satellite Data Centres. Furthermore the SeaDataNet consortium comprises a number of expert modelling centres, SME's experts in IT, and 3 international bodies (ICES, IOC and JRC). Planning: The SeaDataNet project is delivering and operating the infrastructure in 3 versions: Version 0: maintenance and further development of the metadata systems developed by the Sea-Search project plus the development of a new metadata system for indexing and accessing to individual data objects managed by the SeaDataNet data centres.

    2005-12-15

    We retrospectively evaluated the usefulness of both arterial and venous access with the pull-through technique in endovascular treatment of totally occluded Brescia-Cimino fistulas. We treated 26 patients (17 men, 9 women; age range 43-82 years, mean age 66 years) with occluded Brescia-Cimino fistulas. First, the occluded segment was traversed from the antegrade brachial arterial access using a microcatheter-guidewire system. Second, the vein was retrogradely punctured after confirmation of all diseased segments, and a 0.014- or 0.016-inch guidewire was pulled through the venous access when the occluded segment was long. All interventions including thrombolysis, thromboaspiration, angioplasty, and stent placement were performed via the venous access. The occlusion was successfully crossed via the brachial arterial access in 23 patients (88%). In 2 patients it was done from the venous approach. In the remaining patient it was not possible to traverse the occluded segment. The pull-through technique was successful in all 19 attempts. Clinical success was achieved in 96%, the primary patency rates at 6, 12, and 18 months were 83%, 78%, and 69%, the primary assisted patency rates were 92%, 92%, and 72%, and the secondary patency rates were 92%, 92%, and 92%, respectively. Minor complications in 5 patients included venous perforation in 2 (8%), venous rupture in 1 (4%), and regional hematoma in 2 (8%). Our study suggests that endovascular treatments with both arterial and venous access using the pull-through technique are highly effective in restoring function in totally occluded Brescia-Cimino fistulas.

  15. A hollow definitive obturator fabrication technique for management of partial maxillectomy

    PubMed Central

    Patil, Smita Pravinkumar

    2012-01-01

    Maxillary obturator prosthesis is the most frequent treatment option for management of partial or total maxillectomy. Heavy weight of the obturators is often a dislocating factor. Hollowing the prosthesis to reduce its weight is the well established fact. The alternate technique to hollow-out the prosthesis has been described in this article which is a variation of previously described processing techniques. A pre-shaped wax-bolus was incorporated inside the flasks during packing of the heat-polymerized acrylic resin to automatically create the hollow space. The processing technique described is a single step flasking procedure to construct a closed-hollow-obturator prosthesis as a single unit. To best understand the technique, this article describes management of a patient who had undergone partial maxillectomy secondary to squamous cell carcinoma rehabilitated with a hollow-obturator prosthesis.

    The outcome after Lisfranc injuries correlates with anatomic and stable reduction. The best surgical treatment, particularly for the ligamentous Lisfranc injuries, remains controversial. Recent publications suggest that the ligamentous injuries may benefit from primary partial Lisfranc arthrodesis. Most surgeons agree that an appropriate reduction is better and easier achieved by open reduction and stable temporary screw or dorsal plate fixation or by open primary partial arthrodesis than by closed reduction or Kirschner wire fixation. Despite correct surgical technique and postoperative management, symptom-free recovery is uncommon. This article outlines current techniques in the management of Lisfranc injuries and resultant postoperative outcomes in a level I trauma center. PMID:27261809

    Breast cancer is the most common type of malignancy in females. Advances in systemic therapies and radiotherapy (RT) provided long survival rates in breast cancer patients. RT has a major role in the management of breast cancer. During the past 15 years several developments took place in the field of imaging and irradiation techniques, intensity modulated RT, hypofractionation and partial-breast irradiation. Currently, improvements in the RT technology allow us a subsequent decrease in the treatment-related complications such as fibrosis and long-term cardiac toxicity while improving the loco-regional control rates and cosmetic results. Thus, it is crucial that modern radiotherapy techniques should be carried out with maximum care and efficiency. Several randomized trials provided evidence for the feasibility of modern radiotherapy techniques in the management of breast cancer. However, the role of modern radiotherapy techniques in the management of breast cancer will continue to be defined by the mature results of randomized trials. Current review will provide an up-to-date evidence based data on the role of modern radiotherapy techniques in the management of breast cancer. PMID:25114857

    Background WHO recommends prompt diagnosis and quinine plus clindamycin for treatment of uncomplicated malaria in the first trimester and artemisinin-based combination therapies in subsequent trimesters. We undertook a systematic review of women's access to and healthcare provider adherence to WHO case management policy for malaria in pregnant women. Methods and Findings We searched the Malaria in Pregnancy Library, the Global Health Database, and the International Network for the Rational Use of Drugs Bibliography from 1 January 2006 to 3 April 2014, without language restriction. Data were appraised for quality and content. Frequencies of women's and healthcare providers' practices were explored using narrative synthesis and random effect meta-analysis. Barriers to women's access and providers' adherence to policy were explored by content analysis using NVivo. Determinants of women's access and providers' case management practices were extracted and compared across studies. We did not perform a meta-ethnography. Thirty-seven studies were included, conducted in Africa (30), Asia (4), Yemen (1), and Brazil (2). One- to three-quarters of women reported malaria episodes during pregnancy, of whom treatment was sought by >85%. Barriers to access among women included poor knowledge of drug safety, prohibitive costs, and self-treatment practices, used by 5%–40% of women. Determinants of women's treatment-seeking behaviour were education and previous experience of miscarriage and antenatal care. Healthcare provider reliance on clinical diagnosis and poor adherence to treatment policy, especially in first versus other trimesters (28%, 95% CI 14%–47%, versus 72%, 95% CI 39%–91%, p = 0.02), was consistently reported. Prescribing practices were driven by concerns over side effects and drug safety, patient preference, drug availability, and cost. Determinants of provider practices were access to training and facility type (public versus private). Findings were limited

  2. A Typology of Intellectual Property Management for Public Health Innovation and Access: Design Considerations for Policymakers§

    PubMed Central

    Taubman, Antony

    2010-01-01

    This paper seeks to set the practical discipline of public interest intellectual property (IP) management in public health into its broader policy context. The most immediate and direct impact of IP systems on public welfare results not from international standards nor from national legislation – though these norms are fundamentally important - but rather from the accumulated impact of numerous practical choices whether or not to seek IP protection; where and where not; and how any exclusive rights are deployed, by whom, and to what end. IP management is the essentially practical exercise of limited exclusive rights over protected subject matter, the judicious use of those rights to leverage outcomes that advance an institution's or a firm's objectives. Exclusive rights are used to construct and define knowledge-based relationships, to leverage access to technology and other necessary resources, and to enhance market-based incentives. IP management choices range across a broad spectrum, spanning public domain strategies, open or exclusive licensing, and strong exclusivity. The idea of ‘exclusive rights’, as a specific legal mechanism, can run counter to expectations of greater openness and accessibility, but actual outcomes will depend very much on how these mechanisms are used in practice. For public interest or public sector institutions concerned with health research and development, particularly the development of new medicines, IP management choices can be just as critical as they are for private firms, although a predominant institutional concentration on advancing direct public interest objectives may lead to significantly different approaches in weighing and exercising practical choices for IP management: even so, a private sector approach should not be conflated with exclusivity as an end in itself, nor need public interest IP management eschew all leverage over IP. This paper offers a tentative framework for a richer typology of those choices, to

    BACKGROUND: Sickness absence (SA) is multi-causal and remains a significant problem for employees, employers and society. This makes it necessary to concurrently manage a particular disabling condition and consider the working environment and employee-employer relationship. OBJECTIVE: To describe and examine the components of a novel SA management service Early Access to Support for You (EASY) and discuss their potential influence on the intervention. METHODS: A new sickness absence model, starting from day one of absence, was created called EASY. EASY is planned to support both employees and managers and comprises elements already found to be associated with reduction of SA, such as maintaining regular contact; early biopsychosocial case-management; physiotherapy; mental-health counselling; work modification; phased return-to-work; and health promotion activities. RESULTS: During the EASY implementation period, the SA rate at a health board reversed its trend of being one of the highest rates in the Scottish National Health Service (NHS) and EASY was considered helpful by both managers and employees. CONCLUSIONS: This paper describes an innovative occupational health intervention to sickness absence management based on the bio-psychosocial model to provide early intervention, and discusses the pros and cons of applying cognitive behavioural principles at an early stage in sickness-absence events, in order to improve return-to-work outcomes.

    2009-12-01

    Mercury is a federated metadata harvesting, data discovery and access tool based on both open source packages and custom developed software. It was originally developed for NASA, and the Mercury development consortium now includes funding from NASA, USGS, and DOE. Mercury is itself a reusable toolset for metadata, with current use in 12 different projects. Mercury also supports the reuse of metadata by enabling searching across a range of metadata specification and standards including XML, Z39.50, FGDC, Dublin-Core, Darwin-Core, EML, and ISO-19115. Mercury provides a single portal to information contained in distributed data management systems. It collects metadata and key data from contributing project servers distributed around the world and builds a centralized index. The Mercury search interfaces then allow the users to perform simple, fielded, spatial and temporal searches across these metadata sources. One of the major goals of the recent redesign of Mercury was to improve the software reusability across the projects which currently fund the continuing development of Mercury. These projects span a range of land, atmosphere, and ocean ecological communities and have a number of common needs for metadata searches, but they also have a number of needs specific to one or a few projects To balance these common and project-specific needs, Mercury’s architecture includes three major reusable components; a harvester engine, an indexing system and a user interface component. The harvester engine is responsible for harvesting metadata records from various distributed servers around the USA and around the world. The harvester software was packaged in such a way that all the Mercury projects will use the same harvester scripts but each project will be driven by a set of configuration files. The harvested files are then passed to the Indexing system, where each of the fields in these structured metadata records are indexed properly, so that the query engine can perform

    2015-03-01

    The aim of this present study was to evaluate groundwater quality in the lower part of Nagapattinam district, Tamil Nadu, Southern India. A detailed geochemical study of groundwater region is described, and the origin of the chemical composition of groundwater has been qualitatively evaluated, using observations over a period of two seasons premonsoon (June) and monsoon (November) in the year of 2010. To attempt this goal, samples were analysed for various physico-chemical parameters such as temperature, pH, salinity, Na+, Ca2+, K+, Mg2+, Cl-, HCO3 - and SO4 2-. The abundance of major cations concentration in groundwater is as Na > Ca > Mg > K, while that of anions is Cl > SO4 > HCO3. The Piper trilinear diagram indicates Ca-Cl2 facies, and according to USSL diagram, most of the sample exhibits high salinity hazard (C3S1) type in both seasons. It indicates that high salinity (C3) and low sodium (S1) are moderately suitable for irrigation purposes. Gibbs boomerang exhibits most of the samples mainly controlled by evaporation and weathering process sector in both seasons. Irrigation status of the groundwater samples indicates that it was moderately suitable for agricultural purpose. ArcGIS 9.3 software was used for the generation of various thematic maps and the final groundwater quality map. An interpolation technique inverse distance weighting was used to obtain the spatial distribution of groundwater quality parameters. The final map classified the ground quality in the study area. The results of this research show that the development of the management strategies for the aquifer system is vitally necessary.

  2. Mobility Based Key Management Technique for Multicast Security in Mobile Ad Hoc Networks

    PubMed Central

    Madhusudhanan, B.; Chitra, S.; Rajan, C.

    2015-01-01

    In MANET multicasting, forward and backward secrecy result in increased packet drop rate owing to mobility. Frequent rekeying causes large message overhead which increases energy consumption and end-to-end delay. Particularly, the prevailing group key management techniques cause frequent mobility and disconnections. So there is a need to design a multicast key management technique to overcome these problems. In this paper, we propose the mobility based key management technique for multicast security in MANET. Initially, the nodes are categorized according to their stability index which is estimated based on the link availability and mobility. A multicast tree is constructed such that for every weak node, there is a strong parent node. A session key-based encryption technique is utilized to transmit a multicast data. The rekeying process is performed periodically by the initiator node. The rekeying interval is fixed depending on the node category so that this technique greatly minimizes the rekeying overhead. By simulation results, we show that our proposed approach reduces the packet drop rate and improves the data confidentiality. PMID:25834838

    1982-01-01

    Progress is reported in formulating energy management strategies for stand-alone PV systems, developing an analytical tool that can be used to investigate these strategies, applying this tool to determine the proper control algorithms and control variables (controller inputs and outputs) for a range of applications, and quantifying the relative performance and economics when compared to systems that do not apply energy management. The analysis technique developed may be broadly applied to a variety of systems to determine the most appropriate energy management strategies, control variables and algorithms. The only inputs required are statistical distributions for stochastic energy inputs and outputs of the system and the system's device characteristics (efficiency and ratings). Although the formulation was originally driven by stand-alone PV system needs, the techniques are also applicable to hybrid and grid connected systems.

  4. Using mediation techniques to manage conflict and create healthy work environments.

    PubMed

    Gerardi, Debra

    2004-01-01

    Healthcare organizations must find ways for managing conflict and developing effective working relationships to create healthy work environments. The effects of unresolved conflict on clinical outcomes, staff retention, and the financial health of the organization lead to many unnecessary costs that divert resources from clinical care. The complexity of delivering critical care services makes conflict resolution difficult. Developing collaborative working relationships helps to manage conflict in complex environments. Working relationships are based on the ability to deal with differences. Dealing with differences requires skill development and techniques for balancing interests and communicating effectively. Techniques used by mediators are effective for resolving disputes and developing working relationships. With practice, these techniques are easily transferable to the clinical setting. Listening for understanding, reframing, elevating the definition of the problem, and forming clear agreements can foster working relationships, decrease the level of conflict, and create healthy work environments that benefit patients and professionals.

    Ankyloglossia or “tongue-tie” is a congenital anomaly caused by tight lingual frenulum that abnormally connects the tongue base to the floor of the mouth. Ankyloglossia can results in difficulty during speech and deglutition. This case series presents a novel surgical technique in the management of ankyloglossia in using presuturing technique in which different sets of sutures are given on lingual frenum before severing it. This results in reduced opening of the wound, minimal bleeding, pain and discomfort. Two male patients with severe ankyloglossia had been managed with this technique and after 2 years of follow-up of these cases showed satisfactory protrusive and lateral movement of the tongue with minimal scarring and discomfort.

    Pain is not the sole reason for fear of dentistry. Anxiety or the fear of unknown during dental treatment is a major factor and it has been the major concern for dentists for a long time. Therefore, the main aim of this study was to evaluate and compare the two distraction techniques, viz, audio distraction and audiovisual distraction, in management of anxious pediatric dental patients. Sixty children aged between 4-8 years were divided into three groups. Each child had four dental visits--screening visit, prophylaxis visit, cavity preparation and restoration visit, and extraction visit. Child's anxiety level in each visit was assessed using a combination of four measures: Venham's picture test, Venham's rating of clinical anxiety, pulse rate, and oxygen saturation. The values obtained were tabulated and subjected to statistical analysis. It was concluded that audiovisual distraction technique was more effective in managing anxious pediatric dental patient as compared to audio distraction technique. PMID:18007104

    Background: Management of children’s behavior is an integral component of pediatric dental practice. Objective: To investigate the oral health care providers’ awareness, use and factors for choice of behavior management techniques when attending paediatric dental patients. Methods: A cross-sectional study among dental practitioners in Dar es Salaam, Tanzania. Data collection was done through interview using a structured questionnaire. The recorded information included: awareness and application of behavior management techniques (BMT) when attending a child dental patient, factors influencing choice of a particular technique, socio-demographics, level of professional training, working experience and facility profile. Using SPSS program version 18, frequency distributions and cross tabulations analyses were performed. Results: 74 dental practitioners participated in the study, of whom 49 (66.2%) were males and 44 (59.5%) were graduates. Most participants were aware of the behavior management techniques, ranging from 100% for Tell-Show-Do to 86% for distraction. A small proportion (9.5%) reported to have adequate skills, all of them were graduates. The use of universally accepted BMTs was reported by 65% of experienced practitioners, 61% of graduates, 59% of those reporting to have received formal training and all of those reporting to have fair/inadequate skills to apply BMTs (p= 0.01). Conclusion: Most participants were aware of BMTs, although few acknowledged having adequate skills to apply the techniques. They use BMTs during treatment of paediatric dental patients and their choice of the technique is mainly influenced by children’s factors. PMID:26962374

  12. On the Design of an Architecture for Partitioned Knowledge Management in Autonomic Multimedia Access and Aggregation Networks

    Latré, Steven; Verstichel, Stijn; de Vleeschauwer, Bart; de Turck, Filip; Demeester, Piet

    The recent emergence of multimedia services, such as Network Based Personal Video Recording and Broadcast TV over traditional DSL based access networks, has introduced stringent Quality of Experience (QoE) requirements. It is generally assumed that the wide variety of services and user profiles introduces the need for a per-user or per-subscriber QoE management. Such a complex QoE management requires real-time knowledge about the managed services, which is available amongst the different nodes in the network. However, even for managing a few services, a relatively large amount of, constantly updated, knowledge is needed. Propagating all the knowledge to all nodes is therefore not feasible. As not all knowledge is relevant to all nodes, it is important to perform an intelligent knowledge distribution and management. In this position paper, we introduce the concept of a cognitive model that describes the knowledge requirements of each node. Based on the information stated in this cognitive model, we discuss how filter queries, that typically describe what needs to be queried from other nodes, can be automatically generated leading to an efficient partitioning of the knowledge through the distributed nodes.

    Dawson, Heather; Jones, Michael L.; Irwin, Brian J.; Johnson, Nicholas; Wagner, Michael C.; Szymanski, Melissa

    2016-01-01

    We applied a management strategy evaluation (MSE) model to examine the potential cost-effectiveness of using pheromone-baited trapping along with conventional lampricide treatment to manage invasive sea lamprey. Four pheromone-baited trapping strategies were modeled: (1) stream activation wherein pheromone was applied to existing traps to achieve 10−12 mol/L in-stream concentration, (2) stream activation plus two additional traps downstream with pheromone applied at 2.5 mg/hr (reverse-intercept approach), (3) trap activation wherein pheromone was applied at 10 mg/hr to existing traps, and (4) trap activation and reverse-intercept approach. Each new strategy was applied, with remaining funds applied to conventional lampricide control. Simulating deployment of these hybrid strategies on fourteen Lake Michigan streams resulted in increases of 17 and 11% (strategies 1 and 2) and decreases of 4 and 7% (strategies 3 and 4) of the lakewide mean abundance of adult sea lamprey relative to status quo. MSE revealed performance targets for trap efficacy to guide additional research because results indicate that combining lampricides and high efficacy trapping technologies can reduce sea lamprey abundance on average without increasing control costs.

    2014-01-01

    Background The aim of this study was to assess the efficacy and safety of totally implanted vascular devices (TIVAD) using different techniques of insertion. Methods We performed a retrospective study using a prospective collected database of 796 consecutive oncological patients in which TIVADs were inserted. We focused on early and late complications following different insertion techniques (surgical cutdown, blind and ultrasound guided percutaneous) according to different techniques. Results Ultrasound guided technique was used in 646 cases, cephalic vein cutdown in 102 patients and percutaneous blind technique in 48 patients. The overall complication rate on insertion was 7.2% (57 of 796 cases). Early complications were less frequent using the ultrasound guided technique: arterial puncture (p = 0.009), technical failure (p = 0.009), access site change after first attempt (p = 0.002); pneumothorax occurred in 4 cases, all using the blind percutaneus technique. Late complications occurred in 49 cases (6.1%) which required TIVAD removal in 43 cases and included: sepsis (29 cases), thrombosis (3 cases), dislocation (7 cases), skin dehiscence (3 cases), and severe pain (1 case). Conclusion Ultrasound guided technique is the safest option for TIVAD insertion, with the lowest rates of immediate complications. PMID:24886342

    2013-04-01

    This article details a self-hypnosis technique designed to teach patients how to manage acute or chronic pain through directed focus. The focused suggestion with somatic anchoring technique has been used with various types of pain, including somatic pain (arthritis, post-injury pain from bone breaks, or muscle tears), visceral pain (related to irritable bowel disease), and neuropathic pain (related to multiple sclerosis). This technique combines cognitive restructuring and mindfulness meditation with indirect and direct suggestions during hypnosis. The case examples demonstrate how the focused suggestion with somatic anchoring technique is used with both acute and chronic pain conditions when use of long-term medication has been relatively ineffective.

    2015-01-01

    Double-crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin. Management plans for reducing the size of a large colony on East Sand Island (OR, USA) in the Columbia River estuary are currently being developed. We evaluated habitat enhancement and social attraction as nondestructive techniques for managing cormorant nesting colonies during 2004–2007. We tested these techniques on unoccupied plots adjacent to the East Sand Island cormorant colony. Cormorants quickly colonized these plots and successfully raised young. Cormorants also were attracted to nest and raised young on similar plots at 2 islands approximately 25 km from East Sand Island; 1 island had a history of successful cormorant nesting whereas the other was a site where cormorants had previously nested unsuccessfully. On a third island with no history of cormorant nesting or nesting attempts, these techniques were unsuccessful at attracting cormorants to nest. Our results suggest that some important factors influencing attraction of nesting cormorants using these techniques include history of cormorant nesting, disturbance, and presence of breeding cormorants nearby. These techniques may be effective in redistributing nesting cormorants away from areas where fish stocks of conservation concern are susceptible to predation, especially if sites with a recent history of cormorant nesting are available within their foraging or dispersal range.

    Longitudinal tooth fracture can be classified as craze lines, fractured cusp, cracked tooth, split tooth and vertical root fracture based on extent and severity of the fracture line. The most common type of longitudinal tooth fracture is fractured cusp that poses the treatment dilemma. Retention of the fractured cusp segment temporarily with matrix band followed by permanent bonded restoration and finally removal of tooth fragment during crown preparation is a novel technique. This paper throws light on a matricing and holding technique for the management of supra-crestally fractured palatal cusp of maxillary first premolar in a 29-year-old Asian male. PMID:27190970

    Bezoar is an intraluminal mass formed by the accumulation of undigested material anywhere in the gastrointestinal system. Most of small bezoars are removed by gastrointestinal endoscopy, while the best approach for the larger ones is surgical removal. Currently, laparoscopic technique is successfully used in the treatment of bezoars, which are used to be managed by open surgery. In the laparoscopic treatment of bezoars, contamination of peritoneal cavity is a major problem. We describe a modified laparoscopic technique in which an endobag is placed in the stomach instead of the peritoneal cavity in order to avoid spillage of the bezoar during laparoscopic removal.

  3. An effective and secure key-management scheme for hierarchical access control in E-medicine system.

    PubMed

    Odelu, Vanga; Das, Ashok Kumar; Goswami, Adrijit

    2013-04-01

    Recently several hierarchical access control schemes are proposed in the literature to provide security of e-medicine systems. However, most of them are either insecure against 'man-in-the-middle attack' or they require high storage and computational overheads. Wu and Chen proposed a key management method to solve dynamic access control problems in a user hierarchy based on hybrid cryptosystem. Though their scheme improves computational efficiency over Nikooghadam et al.'s approach, it suffers from large storage space for public parameters in public domain and computational inefficiency due to costly elliptic curve point multiplication. Recently, Nikooghadam and Zakerolhosseini showed that Wu-Chen's scheme is vulnerable to man-in-the-middle attack. In order to remedy this security weakness in Wu-Chen's scheme, they proposed a secure scheme which is again based on ECC (elliptic curve cryptography) and efficient one-way hash function. However, their scheme incurs huge computational cost for providing verification of public information in the public domain as their scheme uses ECC digital signature which is costly when compared to symmetric-key cryptosystem. In this paper, we propose an effective access control scheme in user hierarchy which is only based on symmetric-key cryptosystem and efficient one-way hash function. We show that our scheme reduces significantly the storage space for both public and private domains, and computational complexity when compared to Wu-Chen's scheme, Nikooghadam-Zakerolhosseini's scheme, and other related schemes. Through the informal and formal security analysis, we further show that our scheme is secure against different attacks and also man-in-the-middle attack. Moreover, dynamic access control problems in our scheme are also solved efficiently compared to other related schemes, making our scheme is much suitable for practical applications of e-medicine systems.

    Appropriate airway management is an essential part of anesthesiologist's role. Huge goiters can lead to distorted airway and difficulty in endotracheal intubation. In this report, we present a case of a 67-year-old woman with a huge toxic multinodular thyroid swelling, gradually increasing in size for last 20 years, where trachea was successfully intubated. She had a history of deferred surgery in June 2007 due to inability to intubate, despite 5-6 attempts using different laryngoscopes, bougie, and stylet. Patient was re-admitted in December 2011 for the surgery and was successfully intubated this time with help of fiberoptic intubation using loco-sedative technique. Patient was electively kept intubated postoperatively in view of chances of tracheomalacia due to prolonged large goiter. She was extubated successfully on post-op day 2 after demonstration of leak around trachea following tracheal tube cuff deflation. The different techniques of managing the difficult airway in these patients are discussed. PMID:23717240

    Knowledge of the characteristics of industrial process wastes allows for some innovative and cost savings techniques for investigating and managing these wastes over conventional methods. This paper explores examples of some of these techniques employed on cement kiln dust (CKD) and pulp and paper mill process waste. Similar to Portland Cement, unleached CKD contains free lime and sources of reactive silica and/or alumina. Thus, it can set up in the presence of water. Properly moisture-conditioned CKD has been successfully used in Michigan as a landfill liner and cover material on closures of old CKD piles and newly permitted fills. However, CKD also contains high concentrations of soluble salts and when improperly managed can generate a leachate with high total dissolved solid concentrations. Surface and downhole geophysical methods employing electromagnetic conductivity have proven effective in delineating the horizontal and vertical extent of groundwater plumes caused by releases of CKD leachate.

    Background: Anatomically shaped, form-stable Natrelle 410 breast implants were approved in Europe in 1993 and in the United States in 2013. Although general guidelines for breast augmentation are available, the distinctive characteristics of Natrelle 410 warrant specific guidelines for this device. The goal of this study was to generate consensus recommendations for intraoperative technique and postoperative management with Natrelle 410 in primary breast augmentation. Methods: Surgeons were invited to participate in the study, which used a modified Delphi method. Participants completed 2 rounds of online surveys; the second survey (Recommendations Survey) was generated based on first survey results. Respondents also listed top priorities for use of Natrelle 410. Results: Participants (n = 22) reached consensus on 15 of 18 perioperative and surgical techniques; dual-plane placement, tight pockets, and limiting the boundaries of dissection were among intraoperative techniques considered most important for Natrelle 410. Consensus was reached for 18 of 32 items regarding postoperative management and 6 of 9 open-ended postoperative activity restrictions. Consensus on activity restrictions with specified time limits were similar to consensus recommendations on general restrictions. Top participant-identified intraoperative and postoperative management practices for Natrelle 410 were dual-plane placement of the implant and wearing a bra postoperatively, respectively. Conclusions: The Delphi method identified consensus recommendations on a broad range of intraoperative techniques and postoperative management practices for primary breast augmentation with Natrelle 410. These recommendations and priorities provide surgeons with a framework that, together with the surgeon’s experience, will contribute to optimal clinical outcomes with Natrelle 410. PMID:26893982

    Uncertainty management has always been the key hurdle faced by diagnostics and prognostics algorithms. A Bayesian treatment of this problem provides an elegant and theoretically sound approach to the modern Condition- Based Maintenance (CBM)/Prognostic Health Management (PHM) paradigm. The application of the Bayesian techniques to regression and classification in the form of Relevance Vector Machine (RVM), and to state estimation as in Particle Filters (PF), provides a powerful tool to integrate the diagnosis and prognosis of battery health. The RVM, which is a Bayesian treatment of the Support Vector Machine (SVM), is used for model identification, while the PF framework uses the learnt model, statistical estimates of noise and anticipated operational conditions to provide estimates of remaining useful life (RUL) in the form of a probability density function (PDF). This type of prognostics generates a significant value addition to the management of any operation involving electrical systems.

    2015-01-01

    Perforated peptic ulcer disease remains a relatively frequent emergency surgery presentation. Persistent leak is the most common indication for return to theatre. We present a technique to manage patients in whom a more substantial resection is not possible. A 45-year-old woman underwent initial laparoscopic primary closure of a non-malignant perforated gastric ulcer. This subsequently leaked on return to the UK and had a further graham patch formed via a laparotomy. Unfortunately, the patch repair leaked and at reoperation a wedge excision or distal gastrectomy was not possible given the friability of the tissues and instability of the patient, a transgastric drain and perigastric drain were therefore placed. This created a controlled fistula, which was managed eventually as an outpatient. Transgastric drains in the context of the persistent perforated gastric ulcer leak are a safe way to manage the unstable patient with poor tissues where more substantial surgeries such as a distal gastrectomy are not possible.

    Effective management of biological resources is contingent upon stakeholder compliance with rules. With respect to disease management, partial compliance can undermine attempts to control diseases within human and wildlife populations. Estimating non-compliance is notoriously problematic as rule-breakers may be disinclined to admit to transgressions. However, reliable estimates of rule-breaking are critical to policy design. The European badger (Meles meles) is considered an important vector in the transmission and maintenance of bovine tuberculosis (bTB) in cattle herds. Land managers in high bTB prevalence areas of the UK can cull badgers under license. However, badgers are also known to be killed illegally. The extent of illegal badger killing is currently unknown. Herein we report on the application of three innovative techniques (Randomized Response Technique (RRT); projective questioning (PQ); brief implicit association test (BIAT)) for investigating illegal badger killing by livestock farmers across Wales. RRT estimated that 10.4% of farmers killed badgers in the 12 months preceding the study. Projective questioning responses and implicit associations relate to farmers' badger killing behavior reported via RRT. Studies evaluating the efficacy of mammal vector culling and vaccination programs should incorporate estimates of non-compliance. Mitigating the conflict concerning badgers as a vector of bTB requires cross-disciplinary scientific research, departure from deep-rooted positions, and the political will to implement evidence-based management.

    Recent commentaries have proposed the advantages of using open exchange of data and informatics resources for improving health-related policies and patient care in Africa. Yet, in many African regions, both private medical and public health information systems are still unaffordable. Open exchange over the social Web 2.0 could encourage more altruistic support of medical initiatives. We have carried out some experiments to demonstrate the feasibility of using this approach to disseminate open data and informatics resources in Africa. After the experiments we developed the AFRICA BUILD Portal, the first Social Network for African biomedical researchers. Through the AFRICA BUILD Portal users can access in a transparent way to several resources. Currently, over 600 researchers are using distributed and open resources through this platform committed to low connections.

    The importance of using remote sensing techniques, in the visible and near-infrared ranges, for mapping, inventory, conservation and management of natural ecosystems is discussed. Some examples realized in Brazil or other countries are given to evaluate the products from orbital platform (MSS and RBV imagery of LANDSAT) and aerial level (photography) for ecosystems study. The maximum quantitative and qualitative information which can be obtained from each sensor, at different level, are discussed. Based on the developed experiments it is concluded that the remote sensing technique is a useful tool in mapping vegetation units, estimating biomass, forecasting and evaluation of fire damage, disease detection, deforestation mapping and change detection in land-use. In addition, remote sensing techniques can be used in controling implantation and planning natural/artificial regeneration.

    ABSTRACT Mucocele, a common benign cystic lesion of minor salivary gland and associated ducts develops following extravasation or retention of mucous material in the subepithelial tissue. Occurrence of mucocele of tongue is considered less frequent when compared to a higher incidence of mucocele in the lower lip of young patients. Different modalities of treatment, such as conventional surgical excision followed by newer techniques like cryosurgery, electrocautery have been proposed to completely remove the lesion and reduce the chances of recurrence. Herewith, we report a novel treatment technique using alginate impression material to aid in complete excision of mucocele of glands of Blandin-Nuhn.

    Recent studies of thoracic pressure changes during external cardiopulmonary resuscitation (CPR) suggest that there may be a significant difference in the rate of delivery of intravenous drugs when they are administered through the extrathoracic inferior vena cava (IVC) rather than the intrathoracic superior vena cava (SVC). Comparison of delivery of a radionuclide given using superior and inferior vena caval access sites was made during normal blood flow and during CPR. Mean times from injection to peak emission count in each ventricle were determined. There were no significant differences between mean peak times for SVC or IVC routes during normal flow or CPR. When peak times were corrected for variations in cardiac output, there were no significant differences between IVC and SVC peak times during normal flow. During CPR, however, mean left ventricular peak time, when corrected for cardiac output, was significantly shorter (P less than .05) when the SVC route was used. The mean time for the counts to reach half the ventricular peak was statistically shorter (P less than .05) in both ventricles with the SVC route during the low flow of CPR. This suggests that during CPR, increased drug dispersion may occur when drugs are infused by the IVC route and thus may modify the anticipated effect of the drug bolus. These results suggest that during CPR, both the cardiac output and the choice of venous access are important variables for drug delivery.

    Using widely accessible VR technologies, researchers have implemented a series of multimodal spatial interfaces and virtual environments. The results demonstrate the degree to which we can now use low-cost (for example, mobile-phone based) VR environments to create rich virtual experiences involving motion sensing, physiological inputs, stereoscopic imagery, sound, and haptic feedback. Adapting spatial interfaces to these new platforms can open up exciting application areas for VR. In this case, the application area was in-home VR therapy for patients suffering from persistent pain (for example, arthritis and cancer pain). For such therapy to be successful, a rich spatial interface and rich visual aesthetic are particularly important. So, an interdisciplinary team with expertise in technology, design, meditation, and the psychology of pain collaborated to iteratively develop and evaluate several prototype systems. The video at http://youtu.be/mMPE7itReds demonstrates how the sine wave fitting responds to walking motions, for a walking-in-place application. PMID:24807994

    While poor communication between service users and front-line staff causes many service user complaints in the British National Health Service, staff rarely reflect on the causes of these complaints. We discuss findings from an action research project with midwives which suggest that the midwives struggled to fully understand complaints from women, their partners and families particularly about restricted visiting and the locked door to the midwifery unit. They responded to individual requests to visit out of hours while maintaining the general policy of restricted visiting. In this way, the door was a gatekeeping device which allowed access to the unit within certain rules. The locked door remained a barrier to women and their families and as a result was a common source of informal complaints. We argue that the locked door and restricted visiting to the midwifery unit were forms of gatekeeping and boundary making by midwives which reveals a tension between their espoused woman-centred care and contemporary midwifery practice which is increasingly constrained by institutional values.

    The purpose of this case report is to describe the efficacy of a modified Whale's tail technique to achieve primary closure and thereby aid in regeneration of an interdental osseous defect between maxillary central incisors complicated by an aberrant frenal attachment. A healthy 32-year-old female patient reported with the complaint of spacing between her upper front teeth. Clinical examination revealed an aberrant frenum extending into the interdental papilla in relation to the central incisors. There was a 6 mm periodontal pocket in relation to the mesiopalatal aspect of maxillary left central incisor. Intraoral periapical radiograph showed vertical bone loss in relation to mesial aspect of maxillary left central incisor. A modified Whale's tail flap was employed to access the area. The defect was filled with an alloplastic graft. Six months postoperative review showed complete elimination of the pocket along with radiographic bone fill of the defect. PMID:25810604

    We conducted a study to determine the effectiveness of the Ponseti technique in the management of idiopathic congenital clubfoot in patients older than 1 year of age. A total of 19 patients with 28 clubfeet (16 males [84.2%], 3 females [15.8%]) were included in the present study. The mean age at presentation was 2.7 (range 1 to 3.5) years. The results of treatment using the Ponseti technique were evaluated using the Pirani and Dimeglio scoring systems. The mean precorrection total Pirani score was 4.84 (range 3.5 to 5.5) and the mean precorrection Dimeglio score was 12.96 (range 10 to 14). The mean postcorrection total Pirani score was 0.55 (range 0 to 1), and the mean postcorrection Dimeglio score was 2.32 (range 2 to 3). These differences were statistically significant (p < .001 and p < .001, respectively). In 92.8% of the feet, satisfactory correction of the deformity was achieved. The mean number of casts applied was 8 (range 5 to 12). All but 1 (3.6%) of the clubfeet required tenotomy to achieve correction. The mean follow-up duration was 2.7 (range 1.5 to 3.5) years. We have concluded that the Ponseti technique is an effective method for the management of idiopathic congenital clubfoot, even in toddlers. PMID:25128311

    In support of the National Low-Level Waste (LLW) Management Research and Development Program being carried out at Oak Ridge National Laboratory, Science Applications, Inc., conducted a survey of models and monitoring techniques associated with the transport of radionuclides and other chemical species from LLW burial sites. As a result of this survey, approximately 350 models were identified. For each model the purpose and a brief description are presented. To the extent possible, a point of contact and reference material are identified. The models are organized into six technical categories: atmospheric transport, dosimetry, food chain, groundwater transport, soil transport, and surface water transport. About 4% of the models identified covered other aspects of LLW management and are placed in a miscellaneous category. A preliminary assessment of all these models was performed to determine their ability to analyze the transport of other chemical species. The models that appeared to be applicable are identified. A brief survey of the state-of-the-art techniques employed to monitor LLW burial sites is also presented, along with a very brief discussion of up-to-date burial techniques.

    Due to climate issues and favourable energy market, biogas is spreading as a manure management technique. Digestate is rich in nutrient and has to be handled in order to respect the 'nitrate directive' that limits nitrogen field application in areas defined as vulnerable. In this study, we compared different nitrogen management scenarios: a non-treatment option, a biological short-cut nitrification, a complete autotrophic process (anammox) and ammonia stripping from membrane filtration concentrate. The environmental effect comparison was obtained with 'Cross media effects analysis' and life cycle assessment (LCA). The results were different in some aspects, especially the impacts on eutrophication. According to cross media, the best process is DENO 2, while LCA shows similar impacts for all techniques and the best solution would be the no-treatment option. The main reason to adopt a digestate treatment technique is the lack of area for a correct disposal. If LCA eutrophication results are multiplied with the hectares necessary for each technology, a result similar to that of cross media is obtained. PMID:26020425

    This study evaluated the performance of an upgrading of the micro-marsupialisation technique for the management of mucus extravasation or retention phenomena. This study presents a prospective case series of management of ranulas and mucoceles, with a follow-up ranging from 6 to 18 months. Data included the age and gender of patients, as well as the type, size, and site of lesions, and number of punctures. The treatment performance was evaluated according to: postoperative pain, oedema, secondary infection, clinical healing, retreatment, and recurrence of the lesions. All patients showed clinical healing of the lesions within 30 days after the micro-marsupialisation technique. None of patients presented a recurrence or required retreatment, there was no oedema or infection. No pain, or mild pain was reported by the majority of patients (58.81%). Micro-marsupialisation proved to be a simple, low cost, relatively non-invasive, painless, effective, and low recurrence technique to treat mucus extravasation or retention phenomena. Micro-marsupialisation can be recommended primarily to treat oral ranulas and selected mucoceles. PMID:22613811

    2010-04-01

    Thermoelectric energy harvesting has increasingly gained acceptance as a potential power source that can be used for numerous commercial and military applications. However, power electronic designers have struggled to incorporate energy harvesting methods into their designs due to the relatively small voltage levels available from many harvesting device technologies. In order to bridge this gap, an ultra-low input voltage power conversion method is needed to convert small amounts of scavenged energy into a usable form of electricity. Such a method would be an enabler for new and improved medical devices, sensor systems, and other portable electronic products. This paper addresses the technical challenges involved in ultra-low-voltage power conversion by providing a solution utilizing novel power conversion techniques and applied technologies. Our solution utilizes intelligent power management techniques to control unknown startup conditions. The load and supply management functionality is also controlled in a deterministic manner. The DC to DC converter input operating voltage is 20mV with a conversion efficiency of 90% or more. The output voltage is stored into a storage device such as an ultra-capacitor or lithium-ion battery for use during brown-out or unfavorable harvesting conditions. Applications requiring modular, low power, extended maintenance cycles, such as wireless instrumentation would significantly benefit from the novel power conversion and harvesting techniques outlined in this paper.

    Microbial keratitis is a sight-threatening condition and an ocular emergency, because of the potential for rapid progression. Intensive topical antimicrobials are the mainstay and the gold standard of treatment for microbial keratitis. However, despite appropriate diagnosis and therapy, treatment failure is still common, and can result in significant morbidity due to corneal perforation and/or scarring. For this reason, clinicians continue to seek novel treatment techniques in order to expand the armamentarium of tools available to manage microbial keratitis, and in doing so improve clinical outcomes. In this review, we examine the evidence for some established, as well as a few emerging ancillary techniques used to manage microbial keratitis. These include topical corticosteroids, corneal collagen cross-linking, intrastromal antimicrobials, amniotic membrane transplantation and miscellaneous other techniques. Of these, collagen cross-linking shows some promise for selected cases of infectious keratitis, although more research in the area is required before it is accepted as mainstream treatment for this potentially blinding condition.

    BACKGROUND AND OBJECTIVE Patients with limited English proficiency (LEP) are at risk for undertreated pain. The goal of this study was to examine the association between parental language proficiency, interpreted care, and postsurgical pediatric pain management. METHODS This was a retrospective matched cohort study among children <18 years of age. Children of LEP and English-proficient (EP) parents were matched according to age group, surgical procedure, and admission date. Mean number of daily pain assessments and mean daily pain scores were compared between language groups. We also compared the association between pain scores and type of medication given (opioid versus nonopioid). Within the LEP group, similar analyses compared pain assessment and treatment of children whose families received ≥2 professional interpretations per day versus those who received lower rates of interpretation. RESULTS A total of 474 children (237 LEP and 237 EP) were included in the study. Children of LEP parents had fewer pain assessments (mean: 7 [95% confidence interval: 2–13] vs 9 [95% confidence interval: 4–15]; P = .012), and higher levels of pain recorded before receiving opioid analgesics, compared with children of EP parents (P = .003). Within the LEP group, children with ≥2 interpretations per day had lower pain scores after medication administration (P < .05) and were more likely to receive opioids at pain levels similar to those of EP families. CONCLUSIONS Children of LEP parents received fewer pain assessments and were less likely to receive opioid analgesics for similar levels of pain compared with children of EP parents. More frequent use of professional interpreters when assessing pain may aid in reducing the gap in pain management between LEP and EP pediatric patients. PMID:24435597

    The Magnetospheric Multiscale (MMS) mission and operations are designed to provide maximum reconnection science. Mission phases and the tetrahedral spacecraft formations are chosen to investigate reconnection at the dayside magnetopause and in the magnetotail. At the dayside, the orbits maximize encounters with the magnetopause in regions where the probability of encountering the reconnection diffusion region is high. In the magnetotail, the orbits maximize encounters with the neutral sheet, where reconnection is known to occur episodically. The mission will collect several gigabits per day of particles and field data. Management of these data requires effective selection, transmission, analysis, and storage of data in the ground segment of the mission. Following MMS launch, the Science Operations Center (SOC), located at the Laboratory for Atmospheric and Space Physics (LASP) in Boulder, Colorado, will be actively responsible for instrument suite operations, as well as data production, management, distribution, and archiving of the MMS science data sets. Throughout, the MMS instrument teams work closely with the SOC in conducting instrument operations. The teams will be responsible for much of the science data production activities, with the SOC serving as the Mission Archive and the central node from which data are made available to the science community. The SOC will also handle raw instrument and spacecraft telemetry, calibration data, ephemerides, attitude and other ancillary data needed to support scientific use. Documentation and metadata describing data products, algorithms, instrument calibrations, validation, and data quality will be provided by MMS instrument teams and made available to the user community. A key component of ultimate MMS mission success will be the exploitation of high-resolution burst data products through an innovative burst system and the "Scientist-in-the-Loop" (SITL) concept for key interval identification, downlink, and analysis.

    Nursing homes today are promoting the physical, emotional, and psychosocial security of their residents while involving them and their families in the ultimate decision making. These efforts, however, do not minimize nursing homes' responsibility to ensure a secure environment through good risk management and loss prevention techniques. Facility managers should annually evaluate policies and procedures to ensure that department standards are realistic and reflect the accepted standard of care owed to residents. Technological and functional developments in healthcare make continuous staff training programs a necessity. Involving patients and their families in care planning and treatment decisions can enhance residents' feelings of security. These feelings are further bolstered by a safe environment. Staff should also be alert to changes in residents' behavior. When a resident is admitted to a nursing home, managers should obtain signed consent forms for potential future medical treatment and resident trips. Managers' responsibilities also extend to situations beyond their control. All long-term care facilities must have practical plans in case of natural disasters. PMID:10292223

    2013-07-01

    This article proposes new power management based current control strategy for integrated wind-solar-hydro system equipped with battery storage mechanism. In this control technique, an indirect estimation of load current is done, through energy balance model, DC-link voltage control and droop control. This system features simpler energy management strategy and necessitates few power electronic converters, thereby minimizing the cost of the system. The generation-demand (G-D) management diagram is formulated based on the stochastic weather conditions and demand, which would likely moderate the gap between both. The features of management strategy deploying energy balance model include (1) regulating DC-link voltage within specified tolerances, (2) isolated operation without relying on external electric power transmission network, (3) indirect current control of hydro turbine driven induction generator and (4) seamless transition between grid-connected and off-grid operation modes. Furthermore, structuring of the hybrid system with appropriate selection of control variables enables power sharing among each energy conversion systems and battery storage mechanism. By addressing these intricacies, it is viable to regulate the frequency and voltage of the remote network at load end. The performance of the proposed composite scheme is demonstrated through time-domain simulation in MATLAB/Simulink environment.

    The presence of a nonrecurrent laryngeal nerve (NRLN) during carotid endarterectomy (CEA) may significantly limit the exposure of the surgical field during this operation. Although its reported incidence is rare, NRLN typically overlies the carotid bifurcation and failure to recognize this anatomic variation increases the risk of NRLN injury. A retrospective chart review of all patients who underwent CEA for hemodynamically significant extracranial carotid stenosis between January 2005 and December 2014 was performed. All patients with NRLN encountered intraoperatively were identified. Clinical outcomes, surgical techniques, and complications were reviewed and reported. Four left-sided NRLN were identified and 4 were right sided. No cranial nerve deficits or injuries occurred after CEA in patients where NRLN was encountered. Two distinct surgical techniques were used to manage patients with NRLN and they are discussed in detail. PMID:26965812

    Thyroid cancer is the fifth most common cancer in women with approximately 60,220 expected new cases in the United States in 2013, and the incidence continues to increase each year. Fortunately, the majority are well-differentiated thyroid cancers with excellent overall prognosis. Controversy persists regarding the optimal surgical management of differentiated thyroid cancer in terms of the extent of thyroid resection (thyroid lobectomy vs total thyroidectomy) and the utility of prophylactic central neck dissection (pCND) in low-risk PTC, and papillary thyroid microcarcinoma (PTMC, defined as <10 mm). Thyroid surgical approaches have progressed from the Kocher open incision to minimally invasive techniques that include endoscopic and robotic thyroidectomy. Overall, these minimally invasive techniques have been shown to be safe, and appear to be associated with improved cosmesis and decreased pain compared to open thyroidectomy. PMID:26504264

    This presentation reviews psychologist Jean Piaget's contributions to knowledge of cognitive development in children, relating it to behavior management techniques. Piaget theorized that children's knowledge about reality is realized by touching and observing; he termed this constructivism. He recognized that there are stages of development in knowledge acquisition. Practitioners should try to stimulate these needs to develop a positive dental experience. Another Piaget model is egocentrism, wherein a child views the world subjectively. The dentist should let the child patient know what's going on and have an active part in treatment. PMID:11199558

    Herpes labialis is a common skin infective condition, worldwide, which is primarily caused by HSV-1. Recurrent episodes of herpes labialis, also known as cold sores, can be frequent, painful, long-lasting and disfiguring for infected patients. At present, there are two types of antivirals for the treatment of herpes labialis, topical and oral, which are available over the counter or as prescription-only. The aim of antiviral therapy is to block viral replication to enable shortening the duration of symptoms and to accelerate healing of the lesions associated with herpes labialis. This review examines the evidence for the effectiveness of current topical and oral antivirals in the management of recurrent episodes of herpes labialis. In most countries, oral antivirals for herpes labialis are available as prescription-only. However, in early 2010, the oral antiviral famciclovir was reclassified from prescription-only medicine to pharmacist-controlled status in New Zealand. The benefits and risks associated with moving an antiviral therapy for herpes labialis from prescription-only to pharmacist-controlled status are reviewed here, and the implications for patients, general physicians and pharmacists are considered.

In the present review we have described the development of Electrospray Ionization mass spectrometry (ESI-MS) during the last 25 years in the study of various properties of different types of biological molecules. There have been extensive studies on the mechanism of formation of charged gaseous species by the ESI. Several groups have investigated the origin and implications of the multiple charge states of proteins observed in the ESI-mass spectra of the proteins. The charged analytes produced by ESI can be fragmented by activating them in the gas-phase, and thus tandem mass spectrometry has been developed, which provides very important insights on the structural properties of the molecule. The review will highlight recent developments and emerging directions in this fascinating area of research. PMID:22611397

    Surgical correction is generally indicated as the primary form of management in children with severe early onset scoliosis. Even so, conservative, nonsurgical treatment is always considered first, as surgical correction carries significant concomitant consequences, including but not limited to crankshaft phenomenon and, more importantly, inhibition of further spine, lung, and chest growth in skeletally immature patients. Fusionless surgical procedures assuage some of these risks, as they are characteristically associated with techniques necessitating spinal fusion. One device looks particularly promising in treating and managing severe early onset scoliosis, the vertical expandable prosthetic titanium rib (VEPTR)-a device that was initially targeted toward children with thoracic insufficiency syndrome (TIS). Despite its promising results in correction of severe early onset scoliosis, as well as associated rib and chest wall deformities, the VEPTR nevertheless has a complication rate comparable to other fusionless techniques. Continued modifications and research will hopefully beget a device that permits thoracic and spinal growth in skeletally immature patients yet with fewer postoperative complications. In this chapter, the authors review the clinical experience with VEPTR to date and present their results in 16 children with congenital scoliosis cared for at Shriners Hospital of Philadelphia.

    Estimating how much water is being used by various water users is key to effective management and optimal utilization of groundwater resources. This is especially true for aquifers like the Ogallala that are severely stressed and display depleting trends over the last many years. The High Plains Underground Water Conservation District (HPWD) is the largest and oldest of the Texas water conservation districts, and oversees approximately 1.7 million irrigated acres. Water users within the 16 counties that comprise the HPWD draw from the Ogallala extensively. The HPWD has recently proposed flow-meters as well as various 'alternative methods' for water users to report water usage. Alternative methods include using a) site specific energy conversion factors to convert total amount of energy used (for pumping stations) to water pumped, b) reporting nozzle package (on center pivot irrigation systems) specifications and hours of usage, and c) reporting concentrated animal feeding operations (CAFOs). The focus of this project was to evaluate the reliability and effectiveness for each of these water use estimation techniques for regulatory purposes. Reliability and effectiveness of direct flow-metering devices was also addressed. Findings indicate that due to site-specific variability and hydrogeologic heterogeneity, alternative methods for estimating water use can have significant uncertainties associated with water use estimates. The impact of these uncertainties on overall water usage, conservation, and management was also evaluated. The findings were communicated to the Stakeholder Advisory Group and the Water Conservation District with guidelines and recommendations on how best to implement the various techniques.

    Introduction. Maternal obesity and excessive gestational weight gain are associated with multiple adverse outcomes. There is a lack of clarity on the specific components of effective interventions to support pregnant women with gestational weight management. Method. All 44 studies within a preexisting review of lifestyle interventions, with a potential to impact on maternal weight outcomes, were considered for content analysis. Interventions were classified using Behaviour Change Technique (BCT) taxonomy clusters to explore which categories of BCT were used in interventions and their effectiveness in managing gestational weight gain. Results. The most commonly used BCTs were within the categories of “feedback and monitoring,” “shaping knowledge,” “goals and planning,” “repetition and substitution,” “antecedents,” and “comparison of behaviours.” For diet and mixed interventions “feedback and monitoring,” “shaping knowledge,” and “goals and planning” appeared the most successful BCT categories. Conclusions. Poor reporting within studies in defining the BCTs used, in clarifying the differences in processes between intervention and control groups, and in differentiating between the intervention and research processes made BCT classification difficult. Future studies should elaborate more clearly on the behaviour change techniques used and report them accurately to allow a better understanding of the effective ingredients for lifestyle interventions during pregnancy.

    Like many other developing nations, South Africa faces the challenge of mobilising resources in response to the HIV pandemic. There is a large budget gap between the ideal and the actual amount of funding needed to achieve universal access to highly active antiretroviral therapy (HAART). In addition to financial demands, new burdens are being placed on HAART programmes with the emergence of HIV drug resistance (HIVDR). Thus, a major threat to successful HAART rollout is HIVDR due to non-adherence to HAART. The use of HAART as a primary and secondary HIV-prevention strategy could be ineffective in situations characterised by high rates of non-adherence. In this context, the research looked at issues related to adherence and non-adherence to HAART from the perspective of the provider. Using the software TreeAge Pro 2009, we developed a Markov model to project economic outcomes for a hypothetical cohort of HIV/AIDS patients on HAART. The model compared two scenarios: adherence and non-adherence to HAART. Input data for the model was obtained from existing literature on HAART uptake in South Africa. Moral arguments were analysed and managed through moral reasoning and critical thinking. Discounted lifetime costs for adherent and non-adherent HAART patients in South Africa were estimated at US$9 771 and US$14 762, respectively. The model showed the loss of 4.55 quality-adjusted life years (QALYs) for non-adherent patients, which could be otherwise gained through improved adherence. The incremental cost-effectiveness ratio (ICER) indicated that restricting HAART access only to adherent patients was the dominant strategy. We suggest that, although not a panacea, the withholding or withdrawal of treatment from non-adherent individuals as a precautionary intervention has economic and moral merit. PMID:25865513

    Modern spacecraft (as well as most other complex mechanisms like aircraft, automobiles, and chemical plants) rely more and more on software, to a point where software failures have caused severe accidents and loss of missions. Software failures during a manned mission can cause loss of life, so there are severe requirements to make the software as safe and reliable as possible. Typically, verification and validation (V&V) has the task of making sure that all software errors are found before the software is deployed and that it always conforms to the requirements. Experience, however, shows that this gold standard of error-free software cannot be reached in practice. Even if the software alone is free of glitches, its interoperation with the hardware (e.g., with sensors or actuators) can cause problems. Unexpected operational conditions or changes in the environment may ultimately cause a software system to fail. Is there a way to surmount this problem? In most modern aircraft and many automobiles, hardware such as central electrical, mechanical, and hydraulic components are monitored by IVHM (Integrated Vehicle Health Management) systems. These systems can recognize, isolate, and identify faults and failures, both those that already occurred as well as imminent ones. With the help of diagnostics and prognostics, appropriate mitigation strategies can be selected (replacement or repair, switch to redundant systems, etc.). In this short paper, we discuss some challenges and promising techniques for software health management (SWHM). In particular, we identify unique challenges for preventing software failure in systems which involve both software and hardware components. We then present our classifications of techniques related to SWHM. These classifications are performed based on dimensions of interest to both developers and users of the techniques, and hopefully provide a map for dealing with software faults and failures.

    In all walks of life the way of communication is transformed by the rapid growth of wireless communication and its pervasive use. A wireless network which is fixed and richer in bandwidth is specified as IEEE 802.16, promoted and launched by an industrial forum is termed as Worldwide Interoperability for Microwave Access (WiMAX). This technology enables seamless delivery of wireless broadband service for fixed and/or mobile users. The obscurity is the long delay which occurs during the handoff management in every network. Mobile WiMAX employs an authenticated key management protocol as a part of handoff management in which the Base Station (BS) controls the distribution of keying material to the Mobile Station (MS). The protocol employed is Privacy Key Management Version 2- Extensible Authentication Protocol (PKMV2-EAP) which is responsible for the normal and periodical authorization of MSs, reauthorization as well as key refreshing. Authorization key (AK) and Traffic Encryption key (TEK) plays a vital role in key exchange. When the lifetime of key expires, MS has to request for a new key to BS which in turn leads to repetition of authorization, authentication as well as key exchange. To avoid service interruption during reauthorization , two active keys are transmitted at the same time by BS to MS. The consequences of existing work are hefty amount of bandwidth utilization, time consumption and large storage. It is also endured by Man in the Middle attack and Impersonation due to lack of security in key exchange. This paper designs an automatic mutual refreshing of keys to minimize bandwidth utilization, key storage and time consumption by proposing Previous key and Iteration based Key Refreshing Function (PKIBKRF). By integrating PKIBKRF in key generation, the simulation results indicate that 21.8% of the bandwidth and storage of keys are reduced and PKMV2 mutual authentication time is reduced by 66.67%. The proposed work is simulated with Qualnet model and

    Interrami intraoral Kirschner wire fixation technique is presented for the reduction, stabilization, and immobilization of a pulverized and avulsed lower jaw caused by rifle fragmented bullet injuries. This indirect mandibular war injury fixation technique was tolerated by the patients and tissue more than any indirect external fixation. In addition, it is easier than open reduction using large bone plates for disrupted ballistics mandibular injury defects. An interrami intraoral fixation is appropriate for severely disrupted mandibular hard and soft tissues, and has been adapted in cases of mass casualties and limited resources. Benefits of use include limited hospital beds and fewer follow-up visits. Rifle fragmented bullet injuries need more attention for several reasons: not only because of the higher mortality and devastating nature of the injuries, but also because these injuries are responsible for an unreported type of bullet biomechanism wounding in the craniofacial region. In turn, this necessitates specialized victim management. The survival rates depend on immediate proper execution of airway, breathing, and circulation, which become more complicated as it relates to airway compromise and oropharyngeal hemorrhage resuscitation. Survival is predicated on the implementation of feasible, sensible, life-saving techniques that are applied at the appropriate time. PMID:23851763

    Objective Endovascular techniques are providing options to surgical/percutaneous cell transplantation methods. Some cells, e.g. insulin producing cells, are not suitable for intra-luminal transplantation and for such cells, other options must be found. We have constructed a “nanocatheter” with a penetrating tip for vessel perforation, thereby creating a working channel for parenchymal access by endovascular technique. To finish the procedure safely, the distal tip is detached to provide a securing plug in the vessel wall defect. Materials and Methods We have performed interventions with full clinical integration in the superior mesenteric artery (SMA), the subclavian artery and the external carotid artery in rabbits. No hemorrhagic- or thromboembolic events occurred during the procedure. Stenosis formation and distal embolisation were analyzed by angiography and macroscopic inspection during autopsy at five, 30 and 80 days. All animals and implanted devices were also evaluated by micro-dissections and histochemical analysis. Results In this study we show safety data on the trans-vessel wall technique by behavioral, angiographical and histological analysis. No stenosis formation was observed at any of the follow-up time points. No animals or organs have shown any signs of distress due to the intervention. Histological examination showed no signs of hemorrhage, excellent biocompatibility with no inflammation and a very limited fibrous capsule formation around the device, comparable to titanium implants. Further, no histological changes were detected in the endothelia of the vessels subject to intervention. Conclusions The trans-vessel wall technique can be applied for e.g. cell transplantations, local substance administration and tissue sampling with low risk for complications during the procedure and low risk for hemorrhage, stenosis development or adverse tissue reactions with an 80 days follow-up time. The benefit should be greatest in organs that are

    This paper describes the experience of a hospital which has introduced a system of computerized management of letters of authorization for healthcare workers to access sensitive health data, through the use of open source software. A new corporate intranet portal was created with access given only to the privacy contacts of each operational unit of the hospital. Once the privacy contact has entered the relevant user authorization, these must be approved first by the Directors of the respective operational units and finally by the privacy officer. The introduction of this system has allowed a systematic approach to the management of authorization for access to health data by hospital staff, regular updating and monitoring of the authorization and the start of a process of digitalization of documents.

    The effects of three water management techniques were evaluated on subsurface drip irrigated tomatoes. The three techniques were the intermittent flow (3 pulses), the dual-lateral drip system (two lateral lines per row, at 15 and 25 cm below soil surface), and the physical barrier (buried at 30 cm below soil surface). Field experiments were established for two successive seasons. Water movement in soil was monitored using continuously logging capacitance probes up to 60 cm depth. The results showed that the dual lateral technique positively increased the yield up to 50%, water use efficiency up to 54%, while the intermittent application improved some of the quality measures (fruit size, TSS, and Vitamin C), not the quantity of the yield that decreased in one season, and not affected in the other. The physical barrier has no significant effect on any of the important growth measures. The soil water patterns showed that the dual lateral method lead to uniform wetting pattern with depth up to 45 cm, the physical barrier appeared to increase lateral and upward water movement, while the intermittent application kept the wetting pattern at higher moisture level for longer time. The cost analysis showed also that the economic treatments were the dual lateral followed by the intermittent technique, while the physical barrier is not economical. The study recommends researching the effect of the dual lateral method on the root growth and performance. The intermittent application may be recommended to improve tomato quality but not quantity. The physical barrier is not recommended unless in high permeable soils. PMID:26057380

    Background Previous studies have shown that breathing techniques reduce short acting β2 agonist use and improve quality of life (QoL) in asthma. The primary aim of this double blind study was to compare the effects of breathing exercises focusing on shallow nasal breathing with those of non‐specific upper body exercises on asthma symptoms, QoL, other measures of disease control, and inhaled corticosteroid (ICS) dose. This study also assessed the effect of peak flow monitoring on outcomes in patients using breathing techniques. Methods After a 2 week run in period, 57 subjects were randomised to one of two breathing techniques learned from instructional videos. During the following 30 weeks subjects practised their exercises twice daily and as needed for relief of symptoms. After week 16, two successive ICS downtitration steps were attempted. The primary outcome variables were QoL score and daily symptom score at week 12. Results Overall there were no clinically important differences between the groups in primary or secondary outcomes at weeks 12 or 28. The QoL score remained unchanged (0.7 at baseline v 0.5 at week 28, p = 0.11 both groups combined), as did lung function and airway responsiveness. However, across both groups, reliever use decreased by 86% (p<0.0001) and ICS dose was reduced by 50% (p<0.0001; p>0.10 between groups). Peak flow monitoring did not have a detrimental effect on asthma outcomes. Conclusion Breathing techniques may be useful in the management of patients with mild asthma symptoms who use a reliever frequently, but there is no evidence to favour shallow nasal breathing over non‐specific upper body exercises.

    Background: Timely access to publicly funded health services is a priority issue across the healthcare continuum in Canada. The purpose of this study was to examine wait list management strategies for publicly funded ambulatory rehabilitation services in Ontario, Canada. Methods: Ambulatory rehabilitation services were defined as community occupational therapy (OT) and physiotherapy (PT) services. A mailed self-administered questionnaire was sent to all 374 Ontario publicly funded sites. Descriptive statistics were used to explore management strategies. Results: The response rate was 57.2%. Client acuity was the most common method used to prioritize access across all settings. The most frequently reported methods to manage wait lists included teaching self-management strategies (85.0%), implementing attendance policies (69.5%) and conducting wait list audits (67.3%). Conclusion: Ambulatory rehabilitation settings have implemented a number of strategies for wait list management. The results of this study suggest that an increasing number of Ontarians encounter barriers when accessing publicly funded ambulatory rehabilitation services. PMID:21532763

    ABSTRACT Surgical derotation is a method of placing a rotated tooth in normal alignment in a dental arch; surgically, immediately and permanently. It is a potentially convenient and cost-effective treatment modality as compared to conventional orthodontic procedure for rotated maxillary incisor with open apex. Here is a presentation of a severely rotated maxillary left permanent central incisor in a nine and half years old girl, with a radiographic evidence of immature root apex which was surgically derotated, orthodontically retroclined and intruded to its normal position. Postsurgical clinical and radiographic evaluation was done for a period of one and half years to confirm the vitality and continued physiological root formation of the affected tooth.

    One of only two native, freshwater turtle species in the western United States, western pond turtles are declining in portions of their original range. Declines are mostly due to habitat loss, introduction of non-native species, pollution, and lack of connectivity among populations. USGS zoologist R. Bruce Bury and colleagues from the U.S. Forest Service, California State University, and other agencies compiled and edited a new review and field manual of this charismatic species. Objectives were to determine its current distribution and abundance, summarize and evaluate population features, review techniques to detect population and habitat changes, and improve monitoring for long-term trends. Methods described in the manual should improve consistency, efficiency, and accuracy of survey data, resulting in improved management and conservation efforts.

    2010-08-01

    The effectiveness of Particle-In-Cell (PIC) codes lies mainly in the robustness of the methods implemented, under the fundamental assumption that a sufficient number of pseudo-particles is concerned for a correct representation of the system. The consequent drawback is the huge increase of computational time required to run a simulation, to what concerns the particles charge assignment to the grid and the motion of the former through the latter. Moreover the coupling of such methods with Monte-Carlo-Collisional (MCC) modules causes another expensive computational cost to simulate particle multiple collisions with background gas and domain boundaries. Particles management techniques are therefore often introduced in PIC-MCC codes in order to improve the distribution of pseudo-particles in the simulation domain: as a matter of facts, the aim at managing the number of samples according to the importance of the considered region is a main question for codes simulating a local phenomenon in a larger domain or a strongly collisional system (e.g.: a ionizing plasma, where the number of particles increases exponentially). A clustering procedure based on the distribution function sampling applied to the 5D phase space (2D in space, 3D in velocity) is here proposed, representing the leading criterion for particles merging and splitting procedures guaranteeing the second order charge moments conservation. Applied to the study of the electrical breakdown in the early discharge phase of a Plasma Focus device, this technique is shown to increase performances of both PIC kernel and MCC module preserving the solution of the electric field and increasing samples representativeness in stochastic calculations (with respect to more traditional merging and splitting procedures).

    The two main challenges in the management of bicondylar tibial plateau fractures are: Firstly, the compromised skin and soft tissue envelope which invite a high rate of complications following attempted open reduction and dual plating. Secondly, poor bone quality and comminuted fracture patterns, which create difficulty in achieving stable fixation. Although dual plating is considered to be the best mechanical method of stabilizing these complex fractures, there remains concern regarding the high rate of complications associated with extensive soft tissue dissection, required for the insertion of these plates in an already compromised knee. The Sheffield Hybrid fixator (SHF) technique offers a solution to the two main problems of these difficult fractures by minimizing soft tissue dissection, since bone fragments are reduced and fixed percutaneously, and providing superior cancellous bone purchase with beam loading stabilization for comminuted fractures. Our biomechanical testing showed the SHF with four tensioned wires to be as strong as dual plating and able to provide adequate mechanical stability in the fixation of bicondylar tibial plateau fractures. This was confirmed clinically by a prospective review of the use of the SHF at our centre, for managing complex and high-energy tibial plateau fractures with a good final outcome and no cases of deep infection or septic arthritis.

    Manned space missions require the development of compact, efficient, and reliable life support systems. A number of aqueous biological conversion processes are associated with bioregenerative life support systems. Vessels, or bioreactors, capable of supporting these processes in microgravity must be developed. An annular flow bioreactor has been conceived. It has the potential to incorporate containment, phase separation, gas exchange, and illumination into a single vessel. The bioreactor utilizes capillary fluid management techniques and is configured as a cylindrical tube in which a two-phase liquid-gas flow is maintained. Vanes placed around the inner perimeter enhance capillary forces and cause the liquid phase to attach and flow along the interior surface of the tube. No physical barrier is required to complete phase separation. It is shown analytically that liquid film thickness is limited only by vane geometry and that an annular flow bioreactor capable of managing 284 liters would occupy 0.7 cubic m, less than half the volume of a Spacelab experiment rack.

    As more women survive breast cancer, long-term toxicities affecting their quality of life, such as lymphedema (LE) of the arm, gain importance. Although numerous studies have attempted to determine incidence rates, identify optimal diagnostic tests, enumerate efficacious treatment strategies and outline risk reduction guidelines for breast cancer-related lymphedema (BCRL), few groups have consistently agreed on any of these issues. As a result, standardized recommendations are still lacking. This review will summarize the latest data addressing all of these concerns in order to provide patients and health care providers with optimal, contemporary recommendations. Published incidence rates for BCRL vary substantially with a range of 2-65% based on surgical technique, axillary sampling method, radiation therapy fields treated, and the use of chemotherapy. Newer clinical assessment tools can potentially identify BCRL in patients with subclinical disease with prospective data suggesting that early diagnosis and management with noninvasive therapy can lead to excellent outcomes. Multiple therapies exist with treatments defined by the severity of BCRL present. Currently, the standard of care for BCRL in patients with significant LE is complex decongestive physiotherapy (CDP). Contemporary data also suggest that a multidisciplinary approach to the management of BCRL should begin prior to definitive treatment for breast cancer employing patient-specific surgical, radiation therapy, and chemotherapy paradigms that limit risks. Further, prospective clinical assessments before and after treatment should be employed to diagnose subclinical disease. In those patients who require aggressive locoregional management, prophylactic therapies and the use of CDP can help reduce the long-term sequelae of BCRL.

    Since scholarly interest in corporate social responsibility (CSR) has primarily focused on the synergies between social and economic performance, our understanding of how (and the conditions under which) companies use CSR to produce policy outcomes that work against public welfare has remained comparatively under-developed. In particular, little is known about how corporate decision-makers privately reconcile the conflicts between public and private interests, even though this is likely to be relevant to understanding the limitations of CSR as a means of aligning business activity with the broader public interest. This study addresses this issue using internal tobacco industry documents to explore British-American Tobacco's (BAT) thinking on CSR and its effects on the company's CSR Programme. The article presents a three-stage model of CSR development, based on Sykes and Matza's theory of techniques of neutralization, which links together: how BAT managers made sense of the company's declining political authority in the mid-1990s; how they subsequently justified the use of CSR as a tool of stakeholder management aimed at diffusing the political impact of public health advocates by breaking up political constituencies working towards evidence-based tobacco regulation; and how CSR works ideologically to shape stakeholders' perceptions of the relative merits of competing approaches to tobacco control. Our analysis has three implications for research and practice. First, it underlines the importance of approaching corporate managers' public comments on CSR critically and situating them in their economic, political and historical contexts. Second, it illustrates the importance of focusing on the political aims and effects of CSR. Third, by showing how CSR practices are used to stymie evidence-based government regulation, the article underlines the importance of highlighting and developing matrices to assess the negative social impacts of CSR.

    A study was undertaken to compare the efficacy of two surgical techniques for the treatment of caudal cervical spondylomyelopathy (CCSM): ventral decompression (slot) and vertebral distraction and stabilisation with a screw and washer (screw/washer). Twenty-eight dobermanns managed surgically for disc-associated CCSM during a four-year period were studied retrospectively. The maximum postoperative period was 40 months. Cases were excluded if a minimum follow-up of 24 months after surgery could not be made. A 'slot' took a longer time to perform and had a higher rate of immediate postoperative deterioration. Duration of hospital stay was similar for both procedures. At six months after surgery the two techniques were comparable; 12/14 (screw/washer) and 13/14 (slot) patients were deemed to have a satisfactory outcome. Recurrence of cervical spinal cord disease was higher in the screw/washer dogs. At one year after surgery the recurrence rate was zero (slot) and 5/14 (screw/washer), respectively. At two years after surgery 4/14 of the slot dogs had deteriorated compared to 7/14 of the screw/washer dogs. Where investigated, the cause of deterioration was either a domino disc lesion or vertebral endplate collapse and dorsal displacement of the screw and washer. PMID:9791829

    Objective: To evaluate the role of an open access heart failure service based at a teaching hospital for the diagnosis and treatment optimisation of patients with heart failure in the community and to identify measures that may further enhance the effectiveness of such a service. Subjects: 963 patients with suspected heart failure seen over an eight year period referred by their general practitioners to the cardiology department at a district general hospital. Main outcome measures: Presence or absence of left ventricular systolic dysfunction (LVSD) (left ventricular ejection fraction < 50% on echocardiography), and determination of the risk factors and predictors of LVSD. Results: The majority of the patients were women (60% v 40%) and elderly (mean age 68.8 years). On echocardiography, only 30.8% were found to have LVSD. Patients were more likely to have LVSD if they were men (42.3% v 23.1%, p < 0.001, relative risk (RR) 1.8), were > 60 years of age (33.5% v 20.8%, p < 0.001, RR 1.6), or had a history of diabetes (49.4% v 29.1%, p < 0.001, RR 1.7), ischaemic heart disease (36.5% v 29.1%, p  =  0.04, RR 1.3), or atrial fibrillation (52.6% v 27.8%, p < 0.001, RR 1.9). An abnormal ECG (48.4% v 19.5%, p < 0.001, RR 2.5) and cardiothoracic ratio > 0.5 on chest radiograph (44.3% v 17.8%, p < 0.001, RR 2.5) were found to be good predictors of LVSD. A normal ECG (negative predictive value 80.5%) and a cardiothoracic ratio of < 0.5 (negative predictive value 82.2%) can be used as baseline measures to identify patients with lower risk of developing LVSD (combined negative predictive value 87.9%). Conclusions: An open access heart failure clinic is effective for the diagnosis and management of chronic heart failure in community based patients. The presence of risk factors and simple baseline tests can be used to identify patients with LVSD in the community. The introduction of a protocol based on these findings into a referral system can improve the efficiency and cost

    Forest ecosystems cover approximately 1/3 of the global land area (and 29.8% in Poland). Since forests are constantly exposed to various types of disturbances - both natural and anthropogenic such as fires, wind, insects outbreaks or clear cuts - it is important to investigate the impact of such damages on the carbon dynamics. This becomes even more important due to the fact that future climate change will most likely result in a higher frequency and intensity of extreme climatic events. Even though wind damages cause large disturbances to forests only few places in the world exist where continuous measurements of carbon exchange (CO2) in windthrown sites are carried out. Besides the opportunity to assess the carbon dynamics following wind disturbance, there is an additional possibility of evaluating differences in post windthrow forest management practices. To fill this knowledge gap we set up two measuring stations in north-western Poland in the 500ha area of pine forest damaged by tornado in July 2012, to assess the impact of such disturbance on CO2 and H2O exchange by use of Eddy Covariance (EC) technique (Tlen I and Tlen II). Both sites are characterized by similar climatic as well as soil conditions and are located 3km from each other. While at the site Tlen I all biomass (coarse and fine woody debris were collected together with stumps) was removed and ploughed thereafter, at Tlen II only trunks and main branches were taken out from the site without ploughing. Total harvested biomass per hectare, as derived from local forest inventory, were almost 18 % higher at Tlen I than Tlen II site (where uprooted stumps were left to decompose). First analysis of the eddy covariance data shows that both sites are significant carbon sources. Emissions of carbon dioxide from the non-ploughed site (Tlen II) are higher than from the ploughed site (Tlen I). Both sites released more than 8.1 t of CO2 per ha during a three month time period (mid July to mid August 2014) after

    2013-12-01

    As the construction of NEON and its transition to operations progresses, more and more data will become available to the scientific community, both from NEON directly and from the concomitant growth of existing data repositories. Many of these datasets include ecological observations of a diversity of taxa in both aquatic and terrestrial environments. Although observational data have been collected and used throughout the history of organismal biology, the field has not yet fully developed a culture of data management, documentation, standardization, sharing and discoverability to facilitate the integration and synthesis of datasets. Moreover, the tools required to accomplish these goals, namely database design, implementation, and management, and automation and parallelization of analytical tasks through computational techniques, have not historically been included in biology curricula, at either the undergraduate or graduate levels. To ensure the success of data-generating projects like NEON in advancing organismal ecology and to increase transparency and reproducibility of scientific analyses, an acceleration of the cultural shift to open science practices, the development and adoption of data standards, such as the DarwinCore standard for taxonomic data, and increased training in computational approaches for biologists need to be realized. Here I highlight several initiatives that are intended to increase access to and discoverability of publicly available datasets and equip biologists and other scientists with the skills that are need to manage, integrate, and analyze data from multiple large-scale projects. The EcoData Retriever (ecodataretriever.org) is a tool that downloads publicly available datasets, re-formats the data into an efficient relational database structure, and then automatically imports the data tables onto a user's local drive into the database tool of the user's choice. The automation of these tasks results in nearly instantaneous execution

    Information on distribution and relative abundance of species is integral to sustainable management, especially if they are to be harvested for subsistence or commerce. In northern Australia, natural landscapes are vast, centers of population few, access is difficult, and Aboriginal resource centers and communities have limited funds and infrastructure. Consequently defining distribution and relative abundance by comprehensive ground survey is difficult and expensive. This highlights the need for simple, cheap, automated methodologies to predict the distribution of species in use, or having potential for use, in commercial enterprise. The technique applied here uses a Geographic Information System (GIS) to make predictions of probability of occurrence using an inductive modeling technique based on Bayes' theorem. The study area is in the Maningrida region, central Arnhem Land, in the Northern Territory, Australia. The species examined, Cycas arnhemica and Brachychiton diversifolius, are currently being 'wild harvested' in commercial trials, involving sale of decorative plants and use as carving wood, respectively. This study involved limited and relatively simple ground surveys requiring approximately 7 days of effort for each species. The overall model performance was evaluated using Cohen's kappa statistics. The predictive ability of the model for C. arnhemica was classified as moderate and for B. diversifolius as fair. The difference in model performance can be attributed to the pattern of distribution of these species. C. arnhemica tends to occur in a clumped distribution due to relatively short distance dispersal of its large seeds and vegetative growth from long-lived rhizomes, while B. diversifolius seeds are smaller and more widely dispersed across the landscape. The output from analysis predicts trends in species distribution that are consistent with independent on-site sampling for each species and therefore should prove useful in gauging the extent of

    This paper investigated several options for environmentally acceptable management techniques of tank bottom oily sludge. In particular, we tested the applicability of managing the sludge by three options: (1) as a fuel supplement; (2) in solidification; (3) as a road material. Environmental testing included determination of heavy metals concentration; toxic organics concentration and radiological properties. The assessment of tank bottom sludge as a fuel supplement included various properties such as proximate analysis, ultimate analysis and energy content. Solidified sludge mixtures and road application sludge mixtures were subjected to leaching using the toxicity characteristic leaching procedure (TCLP). Tank bottom sludge was characterized as having higher concentrations of lead, zinc, and mercury, but lower concentrations of nickel, copper and chromium in comparison with values reported in the literature. Natural occurring radioactive minerals (NORM) activity values obtained on different sludge samples were very low or negligible compared to a NORM standard value of 100Bq/g. The fuel assessment results indicate that the heating values, the carbon content and the ash content of the sludge samples are comparable with bituminous coal, sewage sludge, meat and bone meal and petroleum coke/coal mixture, but lower than those in car tyres and petroleum coke. The nitrogen content is lower than those fuels mentioned above, while the sulfur content seems comparable with bituminous coal, petroleum coke and a petroleum coke/coal mixture. The apparent lack of leachability of metals from solidification and road material sludge applications suggests that toxic metals and organics introduced to these applications are not readily attacked by weak acid solutions and would not be expected to migrate or dissolved into the water. Thus, in-terms of trace metals and organics, the suggested sludge applications would not be considered hazardous as defined by the TCLP leaching procedure

    The purpose of this study was to develop of kinetic analysis method for PACS management and computer-aided diagnosis. We obtained dynamic chest radiographs (512x512, 8bit, 4fps, and 1344x1344, 12bit, 3fps) of five healthy volunteers during respiration using an I.I. system twice, and one healthy volunteer using dynamic FPD system. Optical flows of images were obtained using customized block matching technique, and were divided into a direction, and transformed into the RGB color. Density was determined by the sum pixel length of movement during respiration phase. The made new static image was defined as the "kinetic map". The evaluation of patient's collation was performed with a template matching to the three colors. The same person's each correlation value and similar-coefficient which is defined in this study were statistically significant high (P<0.01). We used the artificial neural network (ANN) for the judgment of the same person. Five volunteers were divided into two groups, three volunteers and two volunteers became a training signal and unknown signal. Correlation value and similar-coefficient was used for the input signal, and ANN was designed so that the same person's probability might be outputted. The average of the specificity of the unknown signal obtained 98.2%. The kinetic map including the imitation tumor was used for the simulation. The tumor was detected by temporal subtraction of kinetic map, and then the superior sensitivity was obtained. Our analysis method was useful in risk management and computer-aided diagnosis.

  17. Investigative and management techniques for cement kiln dust and pulp and paper mill process wastes

    Knowledge of the characteristics of industrial process wastes allows for some innovative and cost savings techniques for investigating and managing these wastes over conventional methods. This paper explores examples of some of these techniques employed on cement kiln dust (CKD) and pulp and paper mill process waste. Similar to Portland Cement, unleached CKD contains free lime and sources of reactive silica and/or alumina. Thus, it can set up in the presence of water. Properly moisture conditioned CKD has been successfully used in Michigan as a landfill liner and cover material on closures of old CKD piles and newly permitted fills. In addition to its pozzolanic properties, CKD contains high concentrations of soluble salts, generating a leachate with high total dissolved solids concentrations. Surface and downhole geophysical methods employing electromagnetic conductivity have proven effective in delineating the horizontal and vertical extent of groundwater plumes. At one paper mill in Alabama where dewatered filter cake had been placed in a lined solid waste facility, liquids that had migrated to the surface due to excessive gas pressures caused unstable working conditions at the surface. Large, vertical french drains and a horizontal drainage blanket consisting of geogrid and sand constructed over the existing waste resulted in dewatering and a substantial increase in waste stability, allowing a vertical expansion to proceed. At a kraft mill in the southeastern US, a geotechnical investigation of a lime mud pond revealed that the stability of the unit would increase by construction of an overlying dike, thereby allowing a vertical expansion to proceed. Finally, laboratory testing and modeling of the behavior of paper mill sludges indicates that they can be used as a landfill cover with permeabilities equivalent to or better than compacted clay.

    A 5-month-old infant was to be treated with elective transarterial embolization for a vein of Galen aneurysmal malformation (VGAM). A team of endovascular surgical neuroradiologists, pediatric interventional radiologists, and pediatric cardiologists attempted conventional femoral arterial access, which was unsuccessful given the small caliber of the femoral arteries and superimposed severe vasospasm. Thereafter, eventual arterial access was achieved by navigating from the venous to the arterial system across the patent foramen ovale following a right femoral venous access. Embolization was then successfully performed. At a later date, the child underwent successful transvenous balloon-assisted embolization and eventual arterial embolization with cure of the VGAM.

    Realization of the economic and environmental value of upland peatlands has led both public and private organizations to implement 'restoration' schemes. The word 'restore' implies that we seek to reverse adverse effects that have occurred and return the ecosystem to a pre-disturbance state. Restoration schemes in UK upland peatlands focus on the objectives of raising the water table through blocking drainage channels and gullies and re-vegetating bare areas of peat that are prone to erosion. The target is often the reinstatement of Sphagnum as a significant part of the peatland flora as this will produce an accumulating peat system. Restoration of a peatland implies that we have knowledge of its previous ecological history from which we can attain a restoration blueprint but restoration schemes often take little, if any, account of the ecological history of the site. This study is an example of how palaeoecological techniques have been employed at a UK upland catchment with findings to support the peatland restoration schemes. The study combined an extensive stratigraphic survey of the catchment and a detailed core-based analysis. Macrofossil, testate amoebae, humification and charcoal analysis were employed to determine the historical representation of Sphagnum at the site, the changes in water-table level, the degree of decomposition and also burning history. Stratigraphic survey and core results show that Sphagnum has played a significant role in parts but not all of the catchment, persisting in the main core until late 19th century. They also demonstrate that the loss of Sphagnum and subsequent abundance of Calluna vulgaris is coincident with evidence of wildfire. Continued absence of Sphagnum and abundance of Calluna vulgaris is coincident with further, less intense, burning likely due to grouse moor management. The 3000 year old record from the main core demonstrates the importance of historical climate change in changing water-table levels, vegetation, and

    InSAR is a remote sensing tool that has applications in both geothermal exploitation and in the management of producing fields. The technique has developed rapidly in recent years and the most evolved algorithms, now capable of providing precise ground movement measurements with unprecedented spatial density over large areas, allow the monitoring of the effects of fluid injection and extraction on surface deformation and the detection of active faults. Multi-interferogram approaches have been used at several geothermal sites in different stages of development. SqueeSAR™, which represents the latest breakthrough in InSAR technology, provides a significant increase in the spatial density of measurement points by exploiting signal returns from both point-like and distributed scatterers. Furthermore, recent satellite radar sensors have a higher spatial resolution (down to 1 m), as well as a higher temporal frequency of image acquisitions (down to a few days). The coupling of the new algorithm with this new generation of satellites provides a valuable tool for monitoring the different phases of geothermal production and in support of the decision making process. Some examples from the US are presented here: the first case study involves the use of InSAR within a suite of tools for exploration of the San Emidio geothermal field in Nevada. This project aimed to develop geophysical techniques to identify and map large aperture fractures for the placement of new production/exploration wells. The second and third examples examine two zones in California: the Salton Sea area, where multi-interferogram InSAR provided an overview of surface deformation at a producing geothermal reservoir. Surface deformation in this area was complex, and the added detail provided insight into the interplay of tectonics and production activities. Additional InSAR studies have also been carried out at the Geysers field in order to evaluate the behavior of an Enhanced Geothermal System (EGS) in

    The history of complete denture impression procedures has been influenced largely by the development of impression materials from which new techniques and ideas arose. The purpose of this study was to compare the retention of complete dentures made by using different impression techniques like conventional, admixed, all green, and functional techniques. The results showed that there was significant difference in retention between the six techniques where functional technique showed the highest mean value of retention followed by elastomeric, all green, and admixed, while cocktail and green stick compound showed the lowest mean value. However, on clinical examination, the retention produced by the six techniques was satisfactory. PMID:25180105

    The papers presented in this issue are focused on developing and validating procedures to improve the overall quality of sterile fruit flies for use in area-wide integrated pest management (AW-IPM) programs with a sterile insect technique (SIT) component. The group was coordinated and partially funded by the Joint FAO/IAEA Programme of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, Vienna, Austria, under a five-year Coordinated Research Project (CRP) on 'Quality Assurance in Mass-Reared and Released Fruit Flies for Use in SIT Programmes'. Participants in the CRP from 16 countries came from both basic and applied fields of expertise to ensure that appropriate and relevant procedures were developed. A variety of studies was undertaken to develop protocols to assess strain compatibility and to improve colonization procedures and strain management. Specific studies addressed issues related to insect nutrition, irradiation protocols, field dispersal and survival, field cage behavior assessments, and enhancement of mating competitiveness. The main objective was to increase the efficiency of operational fruit fly programs using sterile insects and to reduce their cost. Many of the protocols developed or improved during the CRP will be incorporated into the international quality control manual for sterile tephritid fruit flies, standardizing key components of the production, sterilization, shipment, handling, and release of sterile insects.

    Vitiligo is an acquired skin disorder characterized by the destruction of melanocytes resulting in achromic macules and patches involving the affected skin. Multiple methods of treatments have emerged to manage vitiligo, including medical and surgical techniques. Among the surgical techniques described in the management of vitiligo are minipunch grafting, split-thickness skin grafting, hair follicle transplantation, suction blister grafting, and cultured and non-cultured autologous melanocyte transplantation. However, prior to grafting optimal recipient-site preparation is needed for graft survival and successful repigmentation outcomes. Similarly, post-operative care of the recipient site is vital to yielding a viable graft irrespective of the transplantation technique employed. This article reviews the multiple methods employed to prepare the recipient site in vitiligo surgeries and the post-surgical conditions which optimize graft viability. A pubmed search was conducted utilizing the key words listed below. PMID:26157306

    Background Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are still controversial. In this article, we suggest a simple reduction method using a subbrow incision as a treatment for isolated anterior sinus fractures. Methods Between March 2011 and March 2014, 13 patients with isolated frontal sinus fractures were treated by open reduction and internal fixation through a subbrow incision. The subbrow incision line was designed to be precisely at the lower margin of the brow in order to obtain an inconspicuous scar. A periosteal incision was made at 3 mm above the superior orbital rim. The fracture site of the frontal bone was reduced, and bone fixation was performed using an absorbable plate and screws. Results Contour deformities were completely restored in all patients, and all patients were satisfied with the results. Scars were barely visible in the long-term follow-up. No complications related to the procedure, such as infection, uncontrolled sinus bleeding, hematoma, paresthesia, mucocele, or posterior wall and brain injury were observed. Conclusions The subbrow approach allowed for an accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by providing a direct visualization of the fracture. Considering the surgical success of the reduction and the rigid fixation, patient satisfaction, and aesthetic problems, this transcutaneous approach through a subbrow incision is concluded to be superior to the other reduction techniques used in the case of an anterior table frontal sinus fracture.

    For high performance, high angle of attack fighter aircraft, accurate and high fidelity airdata parameters are crucial for the flight control system. At high angle of attack, where small changes in angle of attack can greatly influence aerodynamic properties of the aircraft, the problem of flight control augmentation is extremely complicated. In this flight regime, it is critical that accurate measurements of airdata parameters including angle of attack, angle of sideslip and dynamic pressure are made available for use by the flight augmentation system. But at high angle of attack, it is difficult to measure airdata accurately using conventional intrusive sensing devices, because of upstream vortices and flow separation. To overcome this difficulty, a non-intrusive Flush Airdata Sensing system (FADS) has been developed. The FADS is a simple hardware item with the basic fixture being a hemispherical or conical cap mounted at the nose of the fuselage. A number of small holes are drilled around the cap in annular rings. The pressure at each hole is measured by pressure transducers and related to airdata parameters by a non-linear aerodynamic model derived from potential flow. A 7-hole pressure probe, proposed by the DLR for implementation on an advanced experimental fighter aircraft for airdata measurements at high angle of attack, has redundant measurements in angle of attack, angle of side slip and dynamic pressure to ensure control system augmentation at high angle of attack, in spite of some pressure sensor failure or malfunctioning. Such a system requires an algorithm which detects pressure sensor failure and performs fault management in real time. In this report, a concept for an algorithm using a recursive Kalman filtering technique has been proposed and developed. The algorithm is tested on a 5 hole pressure probe which is used in experimental flights of C-160 Transall aircraft.

    The purpose of this study was to assess differences in the management techniques used by Israeli female and male pediatric dentists. All 112 participants of the meeting of the Israeli Society of Dentistry for Children that was held in February 1999 received a questionnaire which sought information regarding age, sex, behavioral and pharmacological methods used to treat children, having a course in nitrous oxide, general anesthesia, and feelings towards pediatric patients. No differences between female and male dentists were found regarding most management techniques. The majority of dentists used tell-show-do, and gave presents at the end of the appointments. Hypnosis was the least used technique. Papoose board was more prevalent among male dentists than among female dentists. Most dentists reported having the parents present during treatment, and more male dentists used their assistance when restraint was needed. General anesthesia was significantly more prevalent among males than among females (p = 0.01). One-third of the dentists reported feeling aggression toward the pediatric patient. Although not statistically significant, more female dentists reported about feeling aggression than male dentists. Most dentists felt authority towards the pediatric patient. Our findings imply that female and male dentists use similar management techniques when treating children. PMID:12964649

  13. Solid waste management in European countries: a review of systems analysis techniques.

    In the past few decades, solid waste management systems in Europe have involved complex and multi-faceted trade-offs among a plethora of technological alternatives, economic instruments, and regulatory frameworks. These changes resulted in various environmental, economic, social, and regulatory impacts in waste management practices which not only complicate regional policy analysis, but also reshape the paradigm of global sustainable development. Systems analysis, a discipline that harmonizes these integrated solid waste management strategies, has been uniquely providing interdisciplinary support for decision making in this area. Systems engineering models and system assessment tools, both of which enrich the analytical framework of waste management, were designed specifically to handle particular types of problems. Though how to smooth out the barriers toward achieving appropriate systems synthesis and integration of these models and tools to aid in the solid waste management schemes prevalent in European countries still remains somewhat uncertain. This paper conducts a thorough literature review of models and tools illuminating possible overlapped boundaries in waste management practices in European countries and encompassing the pros and cons of waste management practices in each member state of the European Union. Whereas the Southern European Union (EU) countries need to develop further measures to implement more integrated solid waste management and reach EU directives, the Central EU countries need models and tools with which to rationalize their technological choices and management strategies. Nevertheless, considering systems analysis models and tools in a synergistic way would certainly provide opportunities to develop better solid waste management strategies leading to conformity with current standards and foster future perspectives for both the waste management industry and government agencies in European Union.

    The rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg.] is the only plant species worldwide that is cultivated for the commercial production of natural rubber. This study describes the genetic diversity of the Hevea spp. complex that is available in the main ex situ collections of South America, including Amazonian populations that have never been previously described. Genetic data were analyzed to determine the genetic structure of the wild populations, quantify the allelic diversity and suggest the composition of a core collection to capture the maximum genetic diversity within a minimal sample size. A total of 1,117 accessions were genotyped with 13 microsatellite markers. We identified a total of 408 alleles, 319 of which were shared between groups and 89 that were private in different groups of accessions. In a population structure and principal component analysis, the level of clustering reflected a primary division into the following two subgroups: cluster 1, which consisted of varieties from the advanced breeding germplasm that originated from the Wickham and Mato Grosso accessions; and cluster 2, which consisted of the wild germplasm from the Acre, Amazonas, Pará and Rondônia populations and Hevea spp. The analyses revealed a high frequency of gene flow between the groups, with the genetic differentiation coefficient (GST) estimated to be 0.018. Additionally, no distinct separation among the H. brasiliensis accessions and the other species from Amazonas was observed. A core collection of 99 accessions was identified that captured the maximum genetic diversity. Rubber tree breeders can effectively utilize this core collection for cultivar improvement. Furthermore, such a core collection could provide resources for forming an association panel to evaluate traits with agronomic and commercial importance.

    The droopy tip is a common nasal deformity in which the tip is inferiorly rotated. Five hundred consecutive rhinoplasty cases were studied to assess the incidence and causes of the droopy tip deformity and to evaluate the role of three alar cartilage-modifying techniques--lateral crural steal, lateral crural overlay, and tongue in groove--in correcting such a deformity. The external rhinoplasty approach was used in all cases. Only one of the three alar cartilage-modifying techniques was used in each case, and the degree of tip rotation and projection was measured both preoperatively and postoperatively. The incidence of droopy tip was 72 percent, and the use of an alar cartilage-modifying technique was required in 85 percent of these cases to achieve the desired degree of rotation. The main causes of droopy tip included inferiorly oriented alar cartilages (85 percent), overdeveloped scrolls of upper lateral cartilages (73 percent), high anterior septal angle (65 percent), and thick skin of the nasal lobule (56 percent). The lateral crural steal technique increased nasal tip rotation and projection, the lateral crural overlay technique increased tip rotation and decreased tip projection, and the tongue-in-groove technique increased tip rotation without significantly changing the amount of projection. The lateral crural overlay technique resulted in the highest degrees of rotation, followed by the lateral crural steal and finally the tongue-in-groove technique. According to these results, the lateral crural steal technique is best indicated in cases with droopy underprojected nasal tip, the lateral crural overlay technique in cases of droopy overprojected nasal tip, and the tongue-in-groove technique in cases where the droopy nasal tip is associated with an adequate amount of projection.

    The paper presents a Case-Based Reasoning Tool for Breast Cancer Knowledge Management to improve breast cancer screening. To develop this tool, we combine both concepts and techniques of Case-Based Reasoning (CBR) and Data Mining (DM). Physicians and radiologists ground their diagnosis on their expertise (past experience) based on clinical cases. Case-Based Reasoning is the process of solving new problems based on the solutions of similar past problems and structured as cases. CBR is suitable for medical use. On the other hand, existing traditional hospital information systems (HIS), Radiological Information Systems (RIS) and Picture Archiving Information Systems (PACS) don't allow managing efficiently medical information because of its complexity and heterogeneity. Data Mining is the process of mining information from a data set and transform it into an understandable structure for further use. Combining CBR to Data Mining techniques will facilitate diagnosis and decision-making of medical experts.

    This paper reviews the effects of six post-modern management concepts as applied to Turkish forestry. Up to now, Turkish forestry has been constrained, both in terms of its operations and internal organization, by a highly bureaucratic system. The application of new thinking in forestry management, however, has recently resulted in new organizational and production concepts that promise to address problems specific to this Turkish industry and bring about positive changes. This paper will elucidate these specific issues and demonstrate how post-modern management thinking is influencing the administration and operational capacity of Turkish forestry within its current structure.

    Background Dehydration is an important cause of death in patients with Ebola virus disease (EVD). Parenteral fluids are often required in patients with fluid requirements in excess of their oral intake. The peripheral intravenous route is the most commonly used method of parenteral access, but inserting and maintaining an intravenous line can be challenging in the context of EVD. Therefore it is important to consider the advantages and disadvantages of different routes for achieving parenteral access (e.g. intravenous, intraosseous, subcutaneous and intraperitoneal). Objectives To compare the reliability, ease of use and speed of insertion of different parenteral access methods. Search methods We ran the search on 17 November 2014. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid MEDLINE(R) and Ovid OLDMEDLINE(R), Embase Classic + Embase (OvidSP), CINAHL (EBSCOhost), clinicaltrials.gov and screened reference lists. Selection criteria Randomised controlled trials comparing different parenteral routes for the infusion of fluids or medication. Data collection and analysis Two review authors examined the titles and abstracts of records obtained by searching the electronic databases to determine eligibility. Two review authors extracted data from the included trials and assessed the risk of bias. Outcome measures of interest were success of insertion; time required for insertion; number of insertion attempts; number of dislodgements; time period with functional access; local site reactions; clinicians' perception of ease of administration; needlestick injury to healthcare workers; patients' discomfort; and mortality. For trials involving the administration of fluids we also collected data on the volume of fluid infused, changes in serum electrolytes and markers of renal function. We rated the

    Summary Objective To provide an overview of the expansion in public access to electronic biomedical information over the past two decades, with an emphasis on developments to which the U.S. National Library of Medicine contributed. Methods Review of the increasingly broad spectrum of web-accessible genomic data, biomedical literature, consumer health information, clinical trials data, and images. Results The amount of publicly available electronic biomedical information has increased dramatically over the past twenty years. Rising expectations regarding access to biomedical information were stimulated by the spread of the Internet, the World Wide Web, advanced searching and linking techniques. These informatics advances simplified and improved access to electronic information and reduced costs, which enabled inter-organizational collaborations to build and maintain large international information resources and also aided outreach and education efforts The demonstrated benefits of free access to electronic biomedical information encouraged the development of public policies that further increase the amount of information available. Conclusions Continuing rapid growth of publicly accessible electronic biomedical information presents tremendous opportunities and challenges, including the need to ensure uninterrupted access during disasters or emergencies and to manage digital resources so they remain available for future generations.

    PurposeTo describe our experiences with treatment of visceral artery pseudoaneurysms (VAPA) by transcatheter coil embolization using an isolation technique and to propose indications for treating VAPA with this method.Materials and MethodsWe treated 37 patients with VAPA endovascularly: There were 15 pancreaticoduodenal arcade, 10 hepatic, 5 renal, 3 splenic, and 1 each left gastric, gastroepiploic, adrenal, and superior mesenteric artery pseudoaneurysms. Preprocedure computed tomography (CT) and/or angiographic studies confirmed the presence of VAPA in all 37 patients. Using the isolation technique, we embolized vessels at sites distal and proximal to the pseudoaneurysm.ResultsTranscatheter coil embolization with the isolation technique was technically successful in 33 (89%) of 37 patients, and angiogram confirmed the complete disappearance of the VAPA in 32 patients. No major complications occurred during the procedures. In a patient with a pancreaticoduodenal arcade artery pseudoaneurysm, we were unable to control hemorrhage. In 30 of 32 patients who recovered after transcatheter coil embolization using the isolation technique, follow-up CT scan showed no flow in VAPA; they survived without rebleeding. Two of the 32 patients (6%) with confirmed complete disappearance of VAPA on angiogram and CT scan obtained the day after the procedure manifested rebleeding during follow-up.ConclusionTranscatheter coil embolization using the isolation technique is an effective alternative treatment in patients with VAPA. In combination with coil embolization, the isolation technique is particularly useful in patients whose pseudoaneurysms present surgical difficulties.

    The purpose of this study was to identify and summarize the current research evidence on approaches to preventing musculoskeletal disorders (MSD) within Occupational Health and Safety Management Systems (OHSMS). Databases in business, engineering, and health and safety were searched and 718 potentially relevant publications were identified and examined for their relevance. Twenty-one papers met the selection criteria and were subjected to thematic analysis. There was very little literature describing the integration of MSD risk assessment and prevention into management systems. This lack of information may isolate MSD prevention, leading to difficulties in preventing these disorders at an organizational level. The findings of this review argue for further research to integrate MSD prevention into management systems and to evaluate the effectiveness of the approach. PMID:26154224

    Summary: Gynecomastia is a benign proliferation of male breast glandular tissue. Gynecomastia can affect men at any stage of life. Traditional treatment options involved excisional surgeries with periareolar or T-shaped scars, which can leave more visible scars on the chest. The technique presented represents a technique used by the senior author, which relies on ultrasonic liposuction and pull-through technique to remove breast tissue. A retrospective chart review was performed, including all patients who were treated, from 2000 to 2013 by the senior author, for gynecomastia. A deidentified database was created to record patient characteristics, including age, height, weight, ptosis, stage of gynecomastia, and gynecomastia classification. Surgical approaches, complications, and revisions were also recorded. Our experience includes 75 patients with all grades of gynecomastia from 2000 to 2013. These cases span the evolution of our technique to include direct pull-through excision with ultrasound-assisted liposuction. The distribution of the grades I, II, III, and IV ptosis was 30.6%, 36 %, 22.6%, and 10.6% respectively. There were no complications in this series. Only one patient with grade III ptosis required revision surgery. This technique provides a safe and aesthetically pleasing way to treat gynecomastia with a low need for revision. PMID:27482482

    2015-09-01

    Advances in endovascular technology, and access to this technology, have significantly changed the field of vascular surgery. Nowhere is this more apparent than in the treatment of abdominal aortic aneurysms (AAAs), in which endovascular aneurysm repair (EVAR) has replaced the traditional open surgical approach in patients with suitable anatomy. However, approximately one-third of patients presenting with AAAs are deemed ineligible for standard EVAR because of anatomic constraints, the majority of which involve the proximal aneurysmal neck. To overcome these challenges, a bevy of endovascular approaches have been developed to either enhance stent graft fixation at the proximal neck or extend the proximal landing zone to allow adequate apposition to the aortic wall and thus aneurysm exclusion. This article is composed of two sections that together address new endovascular approaches for treating aortic aneurysms with difficult proximal neck anatomy. The first section will explore advancements in the traditional EVAR approach for hostile neck anatomy that maximize the use of the native proximal landing zone; the second section will discuss a technique that was developed to extend the native proximal landing zone and maintain perfusion to vital aortic branches using common, off-the-shelf components: the snorkel technique. While the techniques presented differ in terms of approach, the available clinical data, albeit limited, support the notion that they may both have roles in the treatment algorithm for patients with challenging proximal neck anatomy.

    Highly selective vagotomy is the surgical treatment of choice for duodenal ulcer. It is the procedure that best maintains digestive anatomy and physiology with very few side effects, and widely performed all over the world. It has also been employed to treat gastroesophageal reflux for its many advantages: it reduces gastric acid output; it permits easy access to the gastroesophageal junction, assuring a precise, secure fundoplication. We have been using this technique in open surgery since 1978. This prospective study reproduces with laparoscopic guidance, the same technique we used to employ in open surgery. The purpose is to analyze the laparoscopic procedure and discuss the results in 150 patients who were treated between March 1992 and August 1996. This series deals with 36 patients with duodenal ulcer, 80 with gastroesophageal reflux and 34 who presented both. All the duodenal ulcer patients were treated successfully, with no recurrences to date. Recurrences have been recorded in two complex cases of gastroesophageal reflux. The remaining patients show no clinical evidence of reflux and present normal endoscopic findings, esophageal manometric studies and 24-hour esophageal pH measurements. Laparoscopic surgery with this technique appears to be an interesting alternative to prolonged medical treatment of these diseases in certain refractory patients. PMID:9534356

The EA evaluates the potential impacts of constructing an extension of the Cane Springs Road between Mercury Highway and the 5-01 Road. Three alternative actions are also evaluated: (1) construction of a new road along the existing alignment of the Powerline Road between Mercury Highway and the 5-01 Road, (2) upgrading the existing 5-01 Road, and (3) taking no action. The purpose and need for improving access to the RWMS are addressed in Section 1.0 of the EA. A detailed description of the proposed action and alternatives is in Section 2.0. Section 3.0 describes the affected environment and Section 4.0 the environmental effects of the proposed action and alternatives. Health and transportation effects, accident scenarios, cumulative effects, and other relevant information are found in Sections 5.0 through 12.0 of the EA. DOE determined that the alternative action of upgrading the existing 5-01 Road would best meet the needs of the agency.

    Kaiser Permanente Mid-Atlantic States has developed a fully integrated outpatient information system which currently runs on an IBM ES9000 on a VM platform written in MUMPS. The applications include Lab, Radiology, Transcription, Appointments. Pharmacy, Encounter tracking, Hospitalizations, Referrals, Phone Advice, Pap tracking, Problem list, Immunization tracking, and Patient demographics. They are department specific and require input and output from a dumb terminal. We have developed a physician's work station to access this information using PC compatible computers running Microsoft Windows and a custom Microsoft Visual Basic 2.0 environment which draws from these 14 applications giving the physician a comprehensive view of all electronic medical records. Through rapid prototyping, voluntary participation, formal training and gradual implementation we have created an enthusiastic response. 95% of our physician PC users access the system each month. The use ranges from 0.2 to 3.0 screens of data viewed per patient visit. This response continues to drive the process toward still greater user acceptance and further practice enhancement.

    For the differentiation of benign from malignant thyroidal disease, ultrasound displays anatomic but not histologic features. Other visualization techniques can be used including isotope scanning (radioiodine, 99m technetium, 241 americium fluorescence, 131 cesium, 67 gallium, 75 selenomethionine, 201 thallium, 32 phosphorus, 99m Tc-bleomycin, 197 mercury, 133 xenon), thermography, x-ray techniques (plain films, computed tomographic scan, xeroradiography, chest x-ray barium swallow, lymphography, angiography), and thyroid hormone suppression. Needle biopsy can be done by core biopsy (Vim-Silverman and drill biopsy), large needle biopsy for histologic processing and fine needle aspiration for cytologic interpretation. The latter is the safest, most reliable, and most cost-effective technique currently available to differentiate between benign and malignant thyroidal disease and has great promise for the future.

    Soil erosion is extreme in Mediterranean orchards due to management impact, high rainfall intensities, steep slopes and erodible parent material. Vall d'Albaida is a traditional fruit production area which, due to the Mediterranean climate and marly soils, produces sweet fruits. However, these highly productive soils are left bare under the prevailing land management and marly soils are vulnerable to soil water erosion when left bare. In this paper we study the impact of different agricultural land management strategies on soil properties (bulk density, soil organic matter, soil moisture), soil water erosion and runoff, by means of simulated rainfall experiments and soil analyses. Three representative land managements (tillage/herbicide/covered with vegetation) were selected, where 20 paired plots (60 plots) were established to determine soil losses and runoff. The simulated rainfall was carried out at 55mmh(-1) in the summer of 2013 (<8% soil moisture) for one hour on 0.25m(2) circular plots. The results showed that vegetation cover, soil moisture and organic matter were significantly higher in covered plots than in tilled and herbicide treated plots. However, runoff coefficient, total runoff, sediment yield and soil erosion were significantly higher in herbicide treated plots compared to the others. Runoff sediment concentration was significantly higher in tilled plots. The lowest values were identified in covered plots. Overall, tillage, but especially herbicide treatment, decreased vegetation cover, soil moisture, soil organic matter, and increased bulk density, runoff coefficient, total runoff, sediment yield and soil erosion. Soil erosion was extremely high in herbicide plots with 0.91Mgha(-1)h(-1) of soil lost; in the tilled fields erosion rates were lower with 0.51Mgha(-1)h(-1). Covered soil showed an erosion rate of 0.02Mgha(-1)h(-1). These results showed that agricultural management influenced water and sediment dynamics and that tillage and herbicide

  7. Idiopathic pulmonary fibrosis: the role of the pharmacy benefit manager in providing access to effective, high-value care.

    PubMed

    Morrow, Thomas J

    2015-10-01

    Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrosing interstitial pneumonia of unknown cause that primarily affects individuals aged 60 and older. The economic costs of the disease are significant, with patients twice as likely to be hospitalized and twice as likely to require outpatient medical care as compared with those without IPF, resulting in an additional annual cost to the Medicare system of $1 billion. The first pharmacologic treatments for IPF, nintedanib and pirfenidone, were approved in 2014 for conditional use. Their use is expected to significantly increase the cost of care for this population, given that patients will likely continue to take the medication until their death. The use of these medications requires that payers implement innovative opportunities to manage their utilization and cost, as well as other medical costs related to the disease. Pharmacy benefit managers have an important role to play in managing the cost and appropriate utilization of these new treatments through disease management programs, negotiated discounts and rebates, improved adherence to treatment recommendations, and benefit design to optimize patient care.

    Background: The present study aimed to investigate the effect of stress management training through cognitive-behavioral techniques on stress, social adaptability and depression in women with depression disorders. Materials and Methods: In this study, 40 patients diagnosed with depression who had referred to psychiatry and consultation clinics of Isfahan were randomly selected and assigned to intervention and control groups (20 patients in each group). The intervention group received eight 90-min sessions of stress training through cognitive–behavioral techniques. Data collection tools included Cooper's stress questionnaire, Bell's social adaptability questionnaire and Hamilton's depression scale questionnaire. The participants completed the questionnaires before the intervention and 1 month after the same. Data analysis was performed using covariance analysis. Results: Based on the results, considering variables of stress, social adaptability and depression, the equal variance hypothesis was confirmed. The relationship between pre- and post-test scores on stress, social adaptability and depression was statistically significant (P < 0.001). The modified mean difference was F = 12.45, P < 0.001 on stress; F = 6.88, P < 0.01 on social adaptability; and F = 5.36, P < 0.02 on depression, all of which were significant. Conclusion: Stress management training through cognitive behavioral techniques can play a main role in depression reduction and development of social adaptability through modifying inappropriate social information-processing patterns.

    SeaDataNet is a leading infrastructure in Europe for marine & ocean data management. It is actively operating and further developing a Pan-European infrastructure for managing, indexing and providing access to ocean and marine data sets and data products, acquired via research cruises and other observational activities, in situ and remote sensing. The basis of SeaDataNet is interconnecting 40 National Oceanographic Data Centres and Marine Data Centers from 35 countries around European seas into a distributed network of data resources with common standards for metadata, vocabularies, data transport formats, quality control methods and flags, and access. Thereby most of the NODC's operate and/or are developing national networks to other institutes in their countries to ensure national coverage and long-term stewardship of available data sets. The majority of data managed by SeaDataNet partners concerns physical oceanography, marine chemistry, hydrography, and a substantial volume of marine biology and geology and geophysics. These are partly owned by the partner institutes themselves and for a major part also owned by other organizations from their countries. The SeaDataNet infrastructure is implemented with support of the EU via the EU FP6 SeaDataNet project to provide the Pan-European data management system adapted both to the fragmented observation system and the users need for an integrated access to data, meta-data, products and services. The SeaDataNet project has a duration of 5 years and started in 2006, but builds upon earlier data management infrastructure projects, undertaken over a period of 20 years by an expanding network of oceanographic data centres from the countries around all European seas. Its predecessor project Sea-Search had a strict focus on metadata. SeaDataNet maintains significant interest in the further development of the metadata infrastructure, extending its services with the provision of easy data access and generic data products

    This research project was designed as part of a larger effort to help Human Factors (HF) implementers, and others in the aviation maintenance community, understand, evaluate, and validate the impact of Maintenance Resource Management (MRM) training programs, and other MRM interventions; on participant attitudes, opinions, behaviors, and ultimately on enhanced safety performance. It includes research and development of evaluation methodology as well as examination of psychological constructs and correlates of maintainer performance. In particular, during 2001, three issues were addressed. First a prototype process for measuring performance was developed and used. Second an automated calculator was developed to aid the HF implementer user in analyzing and evaluating local survey data. These results include being automatically compared with the experience from all MRM programs studied since 1991. Third the core survey (the Maintenance Resource Management Technical Operations Questionnaire, or 'MRM/TOQ') was further developed and tested to include topics of added relevance to the industry.

  16. A novel tracer technique for the assessment of fine sediment dynamics in urban water management systems.

    Urban storm water run off can reduce the quality of receiving waters due to high sediment load and associated sediment-bound contaminants. Consequently, urban water management systems, such as detention ponds, that both modify water quantity through storage and improve water quality through sediment retention are frequently-used best management practices. To manage such systems effectively and to improve their efficiency, there is a need to understand the dynamics (transport and settling) of sediment, and in particular the fine sediment fraction (<63 μm) and its associated contaminants within urban storm water management systems. This can be difficult to achieve, as modelling the transport behaviour of fine-grained and cohesive sediment is problematic and field-based measurements can be costly, time-consuming and unrepresentative. The aim of this study was to test the application of a novel cohesive sediment tracer and to determine fine sediment transport dynamics within a storm water detention pond. The cohesive sediment tracer used was a holmium labelled montmorillonite clay which flocculated and had similar size and settling velocity to the natural pond sediment it was intended to mimic. The tracer demonstrated that fine sediment was deposited across the entire pond, with the presence of reed beds and water depth being important factors for maximising sediment retention. The results of the sediment tracer experiment were in good agreement with those of a mathematical sediment transport model. Here, the deposited sediment tracer was sampled by collecting and analysing surface pond sediments for holmium. However, analysis and sampling of the three dimensional suspended tracer 'cloud' may provide more accurate information regarding internal pond sediment dynamics. PMID:21420140

    BACKGROUND: Conventional cerebrospinal fluid diversion such as ventriculoperitoneal or ventriculoatrial shunting for the management of hydrocephalus is one of the commonest neurosurgical procedures. However, in selected patients, surgical options are limited when relative contraindications for these operations exist. A patient who underwent ventriculosternal shunting, a novel procedure, is presented with durable and successful outcomes. OBJECTIVE: To demonstrate the feasibility, durability, and safety of ventriculosternal shunting for the management of hydrocephalus. METHODS: A patient with end-stage renal failure and heart failure with recurrent pleural effusion suffered from post–subarachnoid hemorrhage communicating hydrocephalus. Because of the need for continuous ambulatory peritoneal dialysis and the risk of introducing excessive cardiac preloading, conventional shunting was relatively contraindicated. Ventriculosternal shunting was performed by adopting the cancellous matrix of the sternum as the anatomic receptacle for intraosseous cerebrospinal fluid absorption. After placement of the ventricular catheter in the usual manner, the distal end was inserted into the sternum. RESULTS: There was demonstrable clinical and radiological improvement in hydrocephalus by ventriculosternal shunting. Cerebrospinal fluid intraosseous absorption by this novel procedure translated into both physical and cognitive recovery. The procedure was tolerable, effective, and durable, with the patient suffering no complications 3 years after the procedure. CONCLUSION: Ventriculosternal shunting for the management of hydrocephalus is a feasible, safe, and durable surgical treatment option for selected patients when conventional procedures are contraindicated.

    The usual Randomized Clinical Trials (RCT) management using an anachronic procedure involving a flowsheet exchange between the remote centers and the coordinating center presents a number of inadequacies. Eligibility criteria are not always verified by the coordinating center before inclusion in the trial and randomization. Laboratory tests and therapeutic adjustments are frequently decided from memory by the clinician which often leads to data oversight and variability of therapeutic decisions. This results in protocol deviations and alteration of the efficiency of the RCT. HICREN is a medical consultation system designed to take into account the different difficulties encountered during RCT driving. The system integrates a clinical database with artificial intelligence technics to manage clinical trial data on non-expensive and widely available Minitel® terminals. Randomization is then possible, after eligibility criteria are satisfied, anytime and anywhere in France through the national telematic network. HICREN also includes an intuitive graphic interface to increase physician's compliance: a user friendly dialogue manager supports on line data entry with multi-windowing facilities and pull down menus. Interactive data validation is achieved through an interface to dedicated C programs. Patient follow up is achieved by an expert system that proposes appropriate dose of treatment according to the rules defined in the trial. At present, HICREN is implemented on the CISARC system for conducting three randomized clinical trials and one epidemiologic study.

    Optimal pain control in patients undergoing total knee arthroplasty (TKA) is imperative for good rehabilitation and functional outcomes. However, despite technological advancements, surgeons continue to struggle with adequate pain management in their patients. Current modalities in use, such as patient-controlled analgesia, opioids, and epidural anesthetics, provide good pain relief but can be associated with side effects and serious complications. As a result, newer pain control modalities have been used to try to reduce the use of opioids while providing adequate pain relief. Currently, there are no clear guidelines or evidence for an optimum postoperative TKA analgesic regimen. Our aim was to evaluate the recent literature and provide a summary of the newer perioperative analgesic modalities. Evidence suggests that analgesics, such as newer oral medications, peripheral nerve blocks, and periarticular injections, may improve pain management, rehabilitation, and patient satisfaction, as well as reduce opioid consumption. The literature has also highlighted that a multimodal approach to pain management may provide the best results. However, determining which modalities provide superior pain control is still being extensively studied, and further research is needed. PMID:25892004

    Pain following orthopedic surgery is common and often suboptimally managed, with many patients reporting acute moderate to severe pain following surgery. Opioids are often used to manage this pain, yet this can result in significant side effects and complications, including constipation, nausea, vomiting, respiratory distress, and other central nervous system issues. Multimodal therapy that includes surgical site infiltration with extended release local anesthetic has been seen as a new way to minimize this pain for patients, which can result in improved quality of life and shorter length of hospital stay. This article examines the use of bupivacaine liposome injectable suspension (EXPAREL®; Pacira Pharmaceuticals, Inc., San Diego, California), a non-opioid product for pain management. Liposomal bupivacaine uses DepoFoam® technology that allows for the extended release of injected drugs. When used as the foundation of a multimodal regimen, it is effective in reducing postsurgical pain for up to 72 hours while reducing the need for opioids for pain relief. PMID:24911371

    Two obstetric patients presenting with post-traumatic stress disorder in the antenatal period are discussed. The first patient had previously had an unexpected stillborn delivered by emergency caesarean section under general anaesthesia. She developed post-traumatic stress disorder and presented for repeat caesarean section in her subsequent pregnancy, suffering flashbacks and severe anxiety. Following antenatal preparation with hypnosis and a psychological method called the rewind technique, she had a repeat caesarean section under spinal anaesthesia, successfully managing her anxiety. The second patient suffered post-traumatic stress disorder symptoms after developing puerperal psychosis during the birth of her first child. Before the birth of her second child, she was taught self-hypnosis, which she used during labour in which she had an uneventful water birth. These cases illustrate the potential value of hypnosis and alternative psychological approaches in managing women with severe antenatal anxiety. PMID:26162981

    Drawing on experiences in New South Wales from 1950 to 1980 in modeling and re-use techniques in the development of desalination technology and its application in fresh water production for potable use, the paper describes how Australia realized its responsibilities in developing participative and sustainable approaches to land use and water resources management. An analysis of the lessons from the operation of the Bayswater zero-discharge power station significantly contributed to the debate on sustainable approaches, highlighting that no management policy of a water basin can be implemented without a model based on reliable data from all sectors (including the environment), and no management model can be implemented without the participation of all stakeholders. These ideals were reflected in the conception and establishment of the Murray-Darling Basin Commission. The Commission succeeded in bringing together all major stakeholders in this huge basin, though it took more than 15 years to do so. While widely recognized as one of the most advanced and successful experiences in integrated management of a drainage basin, it has still not achieved the reversal of many unsustainable agricultural practices, giving a clear indication of the difficulties and time required for producing sustainable solutions.

    CH2M HILL Hanford Group, Inc. (CH2M HILL) plays a critical role in Hanford Site cleanup for the U. S. Department of Energy, Office of River Protection (ORP). CH2M HILL is responsible for the management of 177 tanks containing 53 million gallons of highly radioactive wastes generated from weapons production activities from 1943 through 1990. In that time, 149 single-shell tanks, ranging in capacity from 50,000 gallons to 500,000 gallons, and 28 double-shell tanks with a capacity of 1 million gallons each, were constructed and filled with toxic liquid wastes and sludges. The cleanup mission includes removing these radioactive waste solids from the single-shell tanks to double-shell tanks for staging as feed to the Waste Treatment Plant (WTP) on the Hanford Site for vitrification of the wastes and disposal on the Hanford Site and Yucca Mountain repository. Concentrated efforts in retrieving residual solid and sludges from the single-shell tanks began in 2003; the first tank retrieved was C-106 in the 200 East Area of the site. The process for retrieval requires installation of modified sluicing systems, vacuum systems, and pumping systems into existing tank risers. Inherent with this process is the removal of existing pumps, thermo-couples, and agitating and monitoring equipment from the tank to be retrieved. Historically, these types of equipment have been extremely difficult to manage from the aspect of radiological dose, size, and weight of the equipment, as well as their attendant operating and support systems such as electrical distribution and control panels, filter systems, and mobile retrieval systems. Significant effort and expense were required to manage this new waste stream and resulted in several events over time that were both determined to be unsafe for workers and potentially unsound for protection of the environment. Over the last four years, processes and systems have been developed that reduce worker exposures to these hazards, eliminate violations

    This work is based in part on a study by the authors to determine the applicability of several concepts to the cooling of high-power linear microwave tubes operating in space under a variety of conditions. The authors focus on: direct radiation to space, beam exit to space, thermal storage, secondary coolant loops/heat pipes, and the use of supercritical hydrogen as a coolant with subsequent ejection to space. Each of these techniques is evaluated within the framework of a neutral particle beam weapons system or other limited duty cycle device which might lay dormant for long periods of time, come to life, and function reliably for a specified time. System impact for each technique is estimated in terms of impact on weight, volume, spacecraft interaction, and ease of implementation.

    2015-01-01

    Prolonging the patency and limiting the complications of a functioning hemodialysis (HD) access require a multidisciplinary approach. It begins with careful access planning that is executed and continually reinforced by physicians and facility staff encouraging active patient participation. Vascular access (VA) dysfunctions identified by regular monitoring and surveillance need further evaluation. Color duplex ultrasound is evolving as the primary tool to evaluate functional implication of the structural problems in the VA. While ease of scheduling makes endovascular management attractive, definitive surgical management provides better longevity and should be used when indicated. Timing of intervention and selection of technique depend on optimal use of available expertise and the nature of the problem. Avoiding a bridging HD catheter should be a priority while prolonging access patency and improving patient safety. PMID:25676299

    Relaxation techniques positively affect the psychosomatic pattern of patients undergoing surgical treatment. Among these techniques guided imaging (GI) has been reported to improve outcome following colorectal surgery. This study assessed the effects of GI on the postoperative course in proctological patients. We carried out a prospective randomized trial in a group of patients operated on for anorectal diseases in our coloproctology unit. Patients were randomized into group 1 (n = 43) with standard care and group 2 (n = 43) with relaxation techniques; they listened to a GI tape with music and relaxing text before, during, and after surgery. The following parameters were evaluated by a questionnaire (a) postoperative pain measured by visual analogue score, (b) the quality of sleep measured by a similar score, and (c) the nature of first micturition, evaluated as normal or difficult. Groups were similar in age and sex distribution, type of disease, and operation performed. The pain score was 3.2 +/- 1.4 in GI patients and 4.1 +/- 2.1 in controls (P = 0.07). The quality of sleep score was 4.8 +/- 2.9 in GI patients and 6.4 +/- 2.7 in controls (P = 0.01). The first micturition was painful in 10.3% of GI patients and in 27.3% of controls (P = 0.09). Perioperative relaxation techniques thus showed a trend to reducing pain following anorectal surgery and significantly improving the quality of sleep; a decrease in anxiety and a consequent muscle relaxation may be involved. Therefore GI, a low cost and noninvasive procedure, can be recommended as an helpful tool in this type of surgery. PMID:11151436

    This report describes a variation of the "posterior-anterior-posterior" surgical techniques to correct posttraumatic kyphosis of the thoracic and lumbar spine with the USS internal fixator. This modification is based on the use of "temporary screws" to mark the entrance of the pedicles in the first stage of the operation (posterior approach, with the patient in prone position). Approaching both columns of the spine simultaneously facilitates correction of the kyphotic defect and permits 360 reconstruction of the spine. PMID:15993120

    The big flood in the upper Elbe River catchment area has revealed a wide spectrum of problems with contaminated sediments. So far, an effective strategy for managing contaminated sediments on a river basin scale is still missing and it seems that not much has been learned from the lessons received during the last decade. In the following overview, special emphasis is given to the utilization of geochemically-based techniques for sediment remediation, which can be applied in different parts of a river basin. The examples presented here are mostly from the Elbe River catchment area. In general, new technical problem solutions need a set of practical process knowledge that uses a wide range of simulation techniques, as well as models in different spatial and temporal scales. The evaluation of recent flood events clearly demonstrates the importance of chemical expertise in the decision-making process for the sustainable development in river basins. PMID:12635960

    Development of flood risk management (FRM) plans is ideally carried out in a participatory process with relevant stakeholders. Integrating stakeholders knowledge and information in the decision making process creates trust amongst decision makers and stakeholders that often leads to a successful implementation of measures. Stakeholder participation however does not come without challenges and hindrances (e.g. limitation of resources, spatial distribution and interest to participate). The most challenging type of participation is Collaborative decision making (CDM). A web-based mobile or computer-aided environment offers an innovative approach to address these challenges and hindrances. Moreover, this also enhances participation. Different phases or steps of a CDM process are addressing relevant management objectives, identify scenarios and sets of proposed alternatives, individually rank these alternatives in order of preference and present an aggregated rank to view the groups position. In individual ranking, formulation of judgement should combine scientific facts with stakeholders' beliefs and attitudes. This paper presents a developed web-based CDM framework and its implementation, highlighting the application of a Muti-Criteria Decision Making (MCDM) method for individual ranking of alternative, the method Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) with Fuzzy logic. Moreover, an innovative visualisation technique for stakeholders' group ranking is also presented. Case studies are the Alster catchment (Hamburg, Germany) and Cranbrook catchment, (London, UK). A series of stakeholders' workshops was done to test and evaluate the environments. It shows that the TOPSIS method provides a close representation of the stakeholders' preferences regarding the measures and alternatives. Overall the evaluation shows that web-based environments can address the challenges and hindrances and it enhances participation in flood risk management. The

    Saving water in irrigated agriculture is increasingly relevant, as the irrigation sector is in many regions the biggest water consumer, but must be a sustainable activity. Therefore, the need urges for water use control methods and water resources planning. In irrigated agriculture, the right way for saving water is constituted by the increase of efficiency in water management. This work validates procedures and methodologies with remote sensing to determine the water availability in the soil at each moment and therefore the opportunity for the application of the water volume strictly necessary to optimize crop growth (irrigation opportunity and irrigation amount). The analysis applied to the Irrigation District of Divor, Évora, having used 7 experiment plots, which are areas watered by center-pivot systems, cultivated to corn. Data were determined from multispectral and infrared images of the cultivated surface obtained by satellite or by flying unmanned platform and integrated with parameters of the atmosphere and of the crops for calculating biophysical indicators and indices of water stress in the vegetation (NDVI, Kc, Kcb, CWSI). Therefore, evapotranspiration (ETc) was estimated, with which crop water requirement was calculated, with the opportunity and the amount of irrigation water to allocate. As this information is geographic referenced, maps can be prepared with GIS technology, describing water situation and the opportunity for watering crops. If the remote images are available with enough high spatial and temporal resolution, the frequent availability of maps can serve as a basis for a farmers irrigation advice system and for the regional irrigation authority to make decisions on the irrigation management at the regional scale. This can be a significant contribute to an efficient water management technology and a sustainable irrigated agriculture.

    'ADMS+/-' is an advanced data base management system whose architecture integrates the ADSM+ mainframe data base system with a large number of work station data base systems, designated ADMS-; no communications exist between these work stations. The use of this system radically decreases the response time of locally processed queries, since the work station runs in a single-user mode, and no dynamic security checking is required for the downloaded portion of the data base. The deferred update strategy used reduces overhead due to update synchronization in message traffic.

    The HIV/AIDS epidemic continues to be a critical public health issue in the United States, where an estimated 1.2 million individuals live with HIV infection. Viral suppression is one of the primary public health goals for People Living with HIV/AIDS (PLWHA). A crucial component of this goal involves adequate access to health care, specifically anti-retroviral HIV medications. The enactment of the Affordable Care Act (ACA) in 2010 raised hopes for millions of PLWHA without access to health care coverage. High cost-sharing requirements enacted by health plans place a financial burden on PLWHA who need ongoing access to these life-saving medications. Plighted with poverty, Detroit, Michigan, is a center of attention for examining the financial burden of HIV medications on PLWHA under the new health plans. From November 2014 to January 2015, monthly out-of-pocket costs and medication utilization requirements for 31 HIV medications were examined for the top 12 insurance carriers offering Qualified Health Plans on Michigan's Health Insurance Marketplace Exchange. The percentage of medications requiring quantity limits and prior authorization were calculated. The average monthly out-of-pocket cost per person ranged from $12 to $667 per medication. Three insurance carriers placed all 31 HIV medications on the highest cost-sharing tier, charging 50% coinsurance. High out-of-pocket costs and medication utilization restrictions discourage PLWHA from enrolling in health plans and threaten interrupted medication adherence, drug resistance, and increased risk of viral transmission. Health plans inflicting high costs and medication restrictions violate provisions of the ACA and undermine health care quality for PLWHA. (Population Health Management 2016;19:272-278).

    The SPICE system of navigation and ancillary data possesses a number of traits that make its use in modern space missions of all types highly cost efficient. The core of the system is a software library providing API interfaces for storing and retrieving such data as trajectories, orientations, time conversions, and instrument geometry parameters. Applications used at any stage of a mission life cycle can call SPICE APIs to access this data and compute geometric quantities required for observation planning, engineering assessment and science data analysis. SPICE is implemented in three different languages, supported on 20+ computer environments, and distributed with complete source code and documentation. It includes capabilities that are extensively tested by everyday use in many active projects and are applicable to all types of space missions - flyby, orbiters, observatories, landers and rovers. While a customer's initial SPICE adaptation for the first mission or experiment requires a modest effort, this initial effort pays off because adaptation for subsequent missions/experiments is just a small fraction of the initial investment, with the majority of tools based on SPICE requiring no or very minor changes.

    The mobile Digital Access to a Web-enhanced Network (mDAWN) program was implemented as an online, mobile self-management system to support patients with type-2 diabetes and their informal caregivers. Patients used wireless physiological sensors, received text messages, and had access to a secure web platform with health resources and semi-facilitated discussion forum. Outcomes were evaluated using (1) pre and post self-reported health behavior measures, (2) physiological outcomes, (3) program cost, and (4) in-depth participant interviews. The group had significantly decreased health distress, HbA1c levels, and systolic blood pressure. Participants largely saw the mDAWN as providing good value for the costs involved and found the program to be empowering in gaining control over their diabetes. mHealth programs have the potential to improve clinical outcomes through cost effective patient-led care for chronic illness. Further evaluation needs to examine integration of similar mHealth programs into the patient-physician relationship. PMID:26958197

    There has been a growing recent interest in the use of elbow hemiarthroplasty for the treatment of distal humeral trauma in select patients. However, the current available evidence regarding outcome after elbow hemiarthroplasty is limited to case series and biomechanical data. Consequently, the procedure remains unfamiliar to many surgeons. The aim of the present review is to outline the evidence regarding elbow hemiarthroplasty and to use this, along with the author's experience, to better describe the indications, surgical technique and outcomes after this procedure.

    Constriction rings are associated with amniotic band syndrome and most often present in the extremities. Constriction bands of the trunk are rare, and a standard of surgical care remains elusive. Traditional methods of constriction ring excision rely on soft-tissue rearrangement with multiple Z-plasties, but renewed interest in linear closure and limited Z-plasty has emerged. The authors review contemporary literature and report two cases of abdominopelvic constriction ring reconstruction with long-term follow-up. Novel techniques including anterior sheath Y-V plasty, pteruges release of the Scarpa fascia, and limited Z-plasty closure may minimize the need for serrated scar patterns. PMID:25626800

    Chronic pain and its associated syndrome have become increasingly prevalent in primary care. With the increase in narcotic use and subsequent adverse events, primary care physicians often seek safer alternatives to treating this condition. Prescribing narcotics necessitates using methods to screen for high abuse risk and protect against misuse. With the understanding of how chronic pain is related to mental illnesses such as depression and posttraumatic stress disorder, mindfulness techniques and behavioral therapy can be used to help decrease the dependence on dangerous opioid medications and help patients understand, accept, and cope with their chronic pain.
