    The Meteorological Automatic Weather Station (MAWS) is a surface meteorological station, manufactured by Vaisala, Inc., dedicated to the balloon-borne sounding system (BBSS), providing surface measurements of the thermodynamic state of the atmosphere and the wind speed and direction for each radiosonde profile. These data are automatically provided to the BBSS during the launch procedure and included in the radiosonde profile as the surface measurements of record for the sounding. The MAWS core set of measurements is: Barometric Pressure (hPa), Temperature (°C), Relative Humidity (%), Arithmetic-Averaged Wind Speed (m/s), and Vector-Averaged Wind Direction (deg). The sensors that collect the core variables are mounted at the standard heights defined for each variable.

    An optimal alimentary tract reconstruction technique after laparoscopic total gastrectomy (LTG) remains controversial. The authors developed a new simple technique for intracorporeal esophagojejunal anastomosis that employs a conventional purse-string suture instrument (PSI) and circular stapler. From May 2014 to April 2016, 41 consecutive patients with gastric cancer underwent LTG in the author's institution. Intracorporeal esophagojejunal anastomosis using the following method was attempted for all patients. After total gastrectomy was completed laparoscopically, a small vertical incision (about 40 mm) was created at the left midclavicular line and retracted by a wound retractor. An anvil of a 25 mm circular stapler was introduced into the abdominal cavity. Then a previously prepared surgical glove, which was cut open at the thumb and the little finger through which the two hand shafts of the PSI were passed separately and sealed by ties, was attached to the wound retractor to maintain airtightness, and the PSI was introduced into the abdominal cavity. The following procedure was similar to conventional open surgery except that it was performed under laparoscopic vision. Intracorporeal esophagojejunal anastomosis was performed successfully for all 41 patients. No case required extension of the initial incision for difficulties during anastomosis. The mean operation time was 245 minutes, and the mean time for the purse-string suture and anvil placement was 15 minutes. Tumor-free margins were achieved in all 41 patients. There were no anastomosis-related complications or other major surgical complications. With the described method, intracorporeal esophagojejunal anastomosis can be performed easily and safely.

    An automatic measuring instrument for the radon daughters concentration of precipitation has been constructed and used successfully. The precipitation collected by a polyethylene funnel during 15 min is led to a glass cell set in a well-type NaI(Tl) scintillator, and after 5 min counting the water sample is pumped out. A sequence of operations of sampling, measurement, recording, draining out and correction for the volume of the water sample is performed automatically, and is repeated at every 15 min. The instrument has sensitivity and durability enough for practical use at outdoors. This instrument enables the measurement of radon daughters concentration as low as 0.5 Bq/ml at precipitation rate as small as 0.5 mm/h. For the improvement of accuracy of the monitoring system of environmental γ-radiation, the effect of radon daughters accumulated on the ground surface by precipitation can be eliminated on real time by means of providing it with the output of this instrument. This instrument can be used for the measurement not only of the radon daughters but also of the other radioactive nuclides in precipitation. (author)

    An infrared instrument used for observation has to keep the detector and optical components in a very cold environment during operation. However, because of maintenance, upgrades, and other routine work, there are situations that require the instrument to be warmed-up and then cooled-down again. At Subaru Observatory, our MOIRCS infrared instrument has required warm-up and cool-down several times a year for routine maintenance and filter replacement. The MOIRCS instrument has a large heat capacity and cool-down using only the closed cycle cooler is impractical due to the huge amount of time it would require. To address this problem Subaru engineers have created a mechanism to allow PRE-COOLING of the instrument via liquid nitrogen - allowing for a much faster pre-cool process. Even with liquid nitrogen, the pre-cool process requires 10 tanks and almost a week of continual monitoring in order to reach the desired target temperature. It is very difficult to work for such a long period of time at the oxygen starved summit of Mauna Kea (4205 meters),and issues of man-power and scheduling conflicts only add to the problems. To address these concerns Subaru developed an automated pre-cooling system which works continuously and remotely at the summit. The strategy was to have basic functionality for pre-cooling and user friendly interface. i.e. (1) Continuous cooling until the target temperature is reached by automated liquid nitrogen tank exchanges and precision temperature control by automated changes to the liquid nitrogen flow. (2) Remote monitoring and control of all parameter setting by Web browser as user interface (UI). The goal of the Subaru pre-cooling system was to make it both inexpensive and quick to implement by using existing technologies. The original goal (to cut down on labor and precision temperature control) has been attained through several pre-cooling and software/hardware modification cycles. We will report on the progress and status of our pre

    Minimally invasive surgery is nowadays a frequently applied technique and can be regarded as a major breakthrough in surgery. The surgeon has to adopt special operation-techniques and deal with difficulties like the complex hand-eye coordination and restricted mobility. To alleviate these constraints we propose to enhance the surgeon's capabilities by providing a context-aware assistance using augmented reality techniques. To analyze the current situation for context-aware assistance, we need intraoperatively gained sensor data and a model of the intervention. A situation consists of information about the performed activity, the used instruments, the surgical objects, the anatomical structures and defines the state of an intervention for a given moment in time. The endoscopic images provide a rich source of information which can be used for an image-based analysis. Different visual cues are observed in order to perform an image-based analysis with the objective to gain as much information as possible about the current situation. An important visual cue is the automatic recognition of the instruments which appear in the scene. In this paper we present the classification of minimally invasive instruments using the endoscopic images. The instruments are not modified by markers. The system segments the instruments in the current image and recognizes the instrument type based on three-dimensional instrument models.

    After the release of new international functional safety standards like IEC 61508, people care more for the safety and availability of safety instrumented systems. Markov analysis is a powerful and flexible technique to assess the reliability measurements of safety instrumented systems, but it is fallible and time-consuming to create Markov models manually. This paper presents a new technique to automatically create Markov models for reliability assessment of safety instrumented systems. Many safety related factors, such as failure modes, self-diagnostic, restorations, common cause and voting, are included in Markov models. A framework is generated first based on voting, failure modes and self-diagnostic. Then, repairs and common-cause failures are incorporated into the framework to build a complete Markov model. Eventual simplification of Markov models can be done by state merging. Examples given in this paper show how explosively the size of Markov model increases as the system becomes a little more complicated as well as the advancement of automatic creation of Markov models

  12. Automatic evaluation and data generation for analytical chemistry instrumental analysis exercises

    Full Text Available In general, laboratory activities are costly in terms of time, space, and money. As such, the ability to provide realistically simulated laboratory data that enables students to practice data analysis techniques as a complementary activity would be expected to reduce these costs while opening up very interesting possibilities. In the present work, a novel methodology is presented for design of analytical chemistry instrumental analysis exercises that can be automatically personalized for each student and the results evaluated immediately. The proposed system provides each student with a different set of experimental data generated randomly while satisfying a set of constraints, rather than using data obtained from actual laboratory work. This allows the instructor to provide students with a set of practical problems to complement their regular laboratory work along with the corresponding feedback provided by the system's automatic evaluation process. To this end, the Goodle Grading Management System (GMS, an innovative web-based educational tool for automating the collection and assessment of practical exercises for engineering and scientific courses, was developed. The proposed methodology takes full advantage of the Goodle GMS fusion code architecture. The design of a particular exercise is provided ad hoc by the instructor and requires basic Matlab knowledge. The system has been employed with satisfactory results in several university courses. To demonstrate the automatic evaluation process, three exercises are presented in detail. The first exercise involves a linear regression analysis of data and the calculation of the quality parameters of an instrumental analysis method. The second and third exercises address two different comparison tests, a comparison test of the mean and a t-paired test.

    The selection of representative areas to be analyzed is a common problem in the study of Cultural Heritage items. UV fluorescence photography is an extensively used technique to highlight specific surface features which cannot be observed in visible light (e.g. restored parts or treated with different materials), and it proves to be very effective in the study of historical musical instruments. In this work we propose a new semi-automatic solution for selecting areas with the same perceived color (a simple clue of similar materials) on UV photos, using a specifically designed interactive tool. The proposed method works in two steps: (i) users select a small rectangular area of the image; (ii) program automatically highlights all the areas that have the same color of the selected input. The identification is made by the analysis of the image in HSV color model, the most similar to the human perception. The achievable result is more accurate than a manual selection, because it can detect also points that users do not recognize as similar due to perception illusion. The application has been developed following the rules of usability, and Human Computer Interface has been improved after a series of tests performed by expert and non-expert users. All the experiments were performed on UV imagery of the Stradivari violins collection stored by "Museo del Violino" in Cremona.

  14. The stapl Skeleton Framework

    Zandifar, Mani

    2015-01-01

    © Springer International Publishing Switzerland 2015. This paper describes the stapl Skeleton Framework, a highlevel skeletal approach for parallel programming. This framework abstracts the underlying details of data distribution and parallelism from programmers and enables them to express parallel programs as a composition of existing elementary skeletons such as map, map-reduce, scan, zip, butterfly, allreduce, alltoall and user-defined custom skeletons. Skeletons in this framework are defined as parametric data flow graphs, and their compositions are defined in terms of data flow graph compositions. Defining the composition in this manner allows dependencies between skeletons to be defined in terms of point-to-point dependencies, avoiding unnecessary global synchronizations. To show the ease of composability and expressivity, we implemented the NAS Integer Sort (IS) and Embarrassingly Parallel (EP) benchmarks using skeletons and demonstrate comparable performance to the hand-optimized reference implementations. To demonstrate scalable performance, we show a transformation which enables applications written in terms of skeletons to run on more than 100,000 cores.

    Flexible bendable instruments are key tools for performing surgical endoscopy. Being able to measure the 3D position of such instruments can be useful for various tasks, such as controlling automatically robotized instruments and analyzing motions. An automatic method is proposed to infer the 3D pose of a single bending section instrument, using only the images provided by a monocular camera embedded at the tip of the endoscope. The proposed method relies on colored markers attached onto the bending section. The image of the instrument is segmented using a graph-based method and the corners of the markers are extracted by detecting the color transitions along Bézier curves fitted on edge points. These features are accurately located and then used to estimate the 3D pose of the instrument using an adaptive model that takes into account the mechanical play between the instrument and its housing channel. The feature extraction method provides good localization of marker corners with images of the in vivo environment despite sensor saturation due to strong lighting. The RMS error on estimation of the tip position of the instrument for laboratory experiments was 2.1, 1.96, and 3.18 mm in the x, y and z directions, respectively. Qualitative analysis in the case of in vivo images shows the ability to correctly estimate the 3D position of the instrument tip during real motions. The proposed method provides an automatic and accurate estimation of the 3D position of the tip of a bendable instrument in realistic conditions, where standard approaches fail.

  17. Food Security and Staple Crops. Staple Food Around the World

    Kilian, Lizette

    2012-01-01

    Of more than 50,000 edible plant species in the world, only a few hundred contribute significantly to our food supplies. Almost all of the world’s food energy intake is satisfied by just a few crop plants. Rice, maize and wheat make up two-thirds of this already small group of foods. These three grains are the staple foods for more than four billion people both as a source of nutrition and income. A staple crop, by definition, dominates the major part of our diet and supplies a major proportion of our energy and nutrient needs. If staple crops are threatened by drought, pests or nutrient-poor soils, hunger and poverty can rise dramatically.

    The Atmosphere-surface Radiation Automatic Instrument (ASRAI) is a newly developed hyper-spectral apparatus by Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (AIOFM, CAS), measuring total spectral irradiance, diffuse spectral irradiance of atmosphere and reflected radiance of the land surface for the purpose of in-situ calibration. The instrument applies VIS-SWIR spectrum (0.4~1.0 μm) with an averaged spectral resolution of 0.004 μm. The goal of this paper is to describe a method of deriving both aerosol optical depth (AOD) and aerosol modes from irradiance measurements under free cloudy conditions. The total columnar amounts of water vapor and oxygen are first inferred from solar transmitted irradiance at strong absorption wavelength. The AOD together with total columnar amounts of ozone and nitrogen dioxide are determined by a nonlinear least distance fitting method. Moreover, it is able to infer aerosol modes from the spectral dependency of AOD because different aerosol modes have their inherent spectral extinction characteristics. With assumption that the real aerosol is an idea of "external mixing" of four basic components, dust-like, water-soluble, oceanic and soot, the percentage of volume concentration of each component can be retrieved. A spectrum matching technology based on Euclidean-distance method is adopted to find the most approximate combination of components. The volume concentration ratios of four basic components are in accordance with our prior knowledge of regional aerosol climatology. Another advantage is that the retrievals would facilitate the TOA simulation when applying 6S model for satellite calibration.

    2010-01-01

    We present the design and implementation of the stapl pList, a parallel container that has the properties of a sequential list, but allows for scalable concurrent access when used in a parallel program. The Standard Template Adaptive Parallel Library (stapl) is a parallel programming library that extends C++ with support for parallelism. stapl provides a collection of distributed data structures (pContainers) and parallel algorithms (pAlgorithms) and a generic methodology for extending them to provide customized functionality. stapl pContainers are thread-safe, concurrent objects, providing appropriate interfaces (e.g., views) that can be used by generic pAlgorithms. The pList provides stl equivalent methods, such as insert, erase, and splice, additional methods such as split, and efficient asynchronous (non-blocking) variants of some methods for improved parallel performance. We evaluate the performance of the stapl pList on an IBM Power 5 cluster and on a CRAY XT4 massively parallel processing system. Although lists are generally not considered good data structures for parallel processing, we show that pList methods and pAlgorithms (p-generate and p-partial-sum) operating on pLists provide good scalability on more than 103 processors and that pList compares favorably with other dynamic data structures such as the pVector. © 2010 Springer-Verlag.

    The Standard Template Adaptive Parallel Library (STAPL) is a C++ parallel programming library that provides a collection of distributed data structures (pContainers) and parallel algorithms (pAlgorithms) and a generic methodology for extending them to provide customized functionality. STAPL algorithms are written in terms of pViews, which provide a generic access interface to pContainer data by abstracting common data structure concepts. Briefly, pViews allow the same pContainer to present multiple interfaces, e.g., enabling the same pMatrix to be \\'viewed\\' (or used) as a row-major or column-major matrix, or even as a vector. In this paper, we describe the stapl pView concept and its properties. pViews generalize the iterator concept and enable parallelism by providing random access to, and an ADT for, collections of elements. We illustrate how pViews provide support for managing the tradeoff between expressivity and performance and examine the performance overhead incurred when using pViews. © 2011 Springer-Verlag Berlin Heidelberg.

    For dental care professionals, the availability and cleanliness of reusable instruments is of major importance. In order to guarantee a proper reprocessing (cleaning, sterilization) of each instrument and ensure optimum safety for the patients, a single instrument traceability solution can be implemented. The RFID (Radio Frequency Identification) technology is the only approach that can provide a fully automated identification of instruments, and a precise monitoring throughout the reprocessing cycle. It consists in integrating a miniature electronic component (RFID tag) to each instrument able to communicate with a transmitter located at a relatively close distance and capable of uniquely identifying each element in any given container, even when closed. In 2011, a pilot project was implemented in collaboration with the Division of Dentistry (SMD) of the University of Geneva and the central sterilization of the Geneva University Hospitals (HUG). This project has demonstrated the applicability and usefulness of RFID technology for tracking reusable dental instruments. In particular, the time saved by the operators and the massive risk reduction when compared to the possible errors during the process of manual identification are two major elements that justify the implementation of an RFID-based instrument traceability solution.

    Accurate tumor segmentation in [18F]-fluorodeoxyglucose positron emission tomography is crucial for tumor response assessment and target volume definition in radiation therapy. Evaluation of segmentation methods from clinical data without ground truth is usually based on physicians’ manual delineations. In this context, the simultaneous truth and performance level estimation (STAPLE) algorithm could be useful to manage the multi-observers variability. In this paper, we evaluated how this algorithm could accurately estimate the ground truth in PET imaging.Complete evaluation study using different criteria was performed on simulated data. The STAPLE algorithm was applied to manual and automatic segmentation results. A specific configuration of the implementation provided by the Computational Radiology Laboratory was used.Consensus obtained by the STAPLE algorithm from manual delineations appeared to be more accurate than manual delineations themselves (80% of overlap). An improvement of the accuracy was also observed when applying the STAPLE algorithm to automatic segmentations results.The STAPLE algorithm, with the configuration used in this paper, is more appropriate than manual delineations alone or automatic segmentations results alone to estimate the ground truth in PET imaging. Therefore, it might be preferred to assess the accuracy of tumor segmentation methods in PET imaging. (paper)

As a matter of fact, the amount of equipment increases proportionally to the increase in safety requirements, resulting in higher costs in spite of the decrease in the prices of each component owing to the advance in electronics. However the improved reliability should improve the plant capacity factor and, as a consequence, improve both the power output and the safety which is often endangered by minor failures starting severe accidents.

    Double-stapling techniques for restorative rectal resection have been effective in minimizing local contamination compared with open circular stapling techniques. Inclusion of the transverse staple line closure of the distal rectal stump in the circular stapled anastomosis may minimize the risk of suture line recurrence. A technique for formation of such an anastomosis is described that avoids use of a distal purse string.

    This second chapter on instrumentation gives little general consideration on history and classification of instrumentation, and two specific states of the art. The first one concerns NMR (block diagram of instrumentation chain with details on the magnets, gradients, probes, reception unit). The first one concerns precision instrumentation (optical fiber gyro-meter and scanning electron microscope), and its data processing tools (programmability, VXI standard and its history). The chapter ends with future trends on smart sensors and Field Emission Displays. (D.L.). Refs., figs

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development. Aspects of instrumentation in operating reactors will also be mentioned.

    Reconstruction of the scaphoid with use of NITINOL shape "memory" staples. Unstable fractures and nonunion of the middle third of the scaphoid, which need open reduction and internal fixation from palmar. The staples can only be used, if the arms of the staples can be inserted parallel to and at a distance of 3 mm to the fracture line. Allergy to nickel. Cases in which the arms of the staple cannot be inserted parallel to and at best 3 mm apart from the fracture line. In fractures, open reduction of the scaphoid through a palmar approach. If necessary, interposition of a bone graft and Kirschner wire transfixation. Drilling of the drill holes parallel and at a distance of 3 mm to the fracture line. Insertion of the NITINOL staple. In nonunion, excision of the fibrous nonunion, refreshening of the fracture surfaces, interposition of a bone graft and, if needed, fixation with a Kirschner wire. Drilling of the drill holes for the NITINOL staple and insertion of the staple. Within a few minutes the warming-up staple contracts and thereby compresses the scaphoid. Immobilization in a short cast with thumb support for 6 weeks. Control for bone healing by radiographs or computed tomography. Staples, which do not cause hardware problems, are not removed. Kirschner wires are removed after bone healing. From October 1995 to December 2006, the authors used NITINOL staples for 65 osteosyntheses of the scaphoid. Indications were 15 unstable fractures, 47 nonunions, and three partial necroses. 61 out of 65 scaphoids healed without further surgery, three of the 61 patients showed a delayed healing. Two of the four nonunions were related to the use of the NITINOL staples. Seven staples were removed, one for loosening. NITINOL shape memory staples have proven to be very helpful for osteosynthesis in fractures and nonunion of the scaphoid, if the prerequisites are given for their use.

    The aim of this study was to investigate the possible deleterious effect of the lateral intersecting margins (so-called dog ears) on anastomotic disruption after experimentally performed double-stapled anastomoses. Two groups of double-stapled side-to-end anastomoses were performed using pig small intestines. Group A consisted of 35 circular anastomoses and Group B of 32 double-stapled anastomoses with a bilateral dog ear. In both groups bursting pressures were tested using a water-filled, pressure-controlled automatic pumping system (Hamou Endomat), and special attention was paid to the location(s) in the anastomoses were the disruption(s) occurred. In Group A bursting pressures were significantly higher than in Group B (median pressure, 90 vs. 60 mmHg; P dog ear. We conclude that the lateral intersections of double-stapled anastomoses are a structural weak spot and that the currently most often applied double-stapled anastomosis is a less effective type of anastomosis than a complete circular one. Resolving this technical problem might help to reduce the number of anastomotic disruptions after low anterior resections.

    The aim of this work was to form NiTi and TiNiCo body temperature activated and superelastic staples for clinical joining of mandible and face bone fractures. The alloys were obtained by VIM technique. Hot and cold processing was applied to obtain wires of required diameters. The martensitic transformation was studied by DSC, XRD, and TEM. The shape memory effects were measured by a bend and free recovery ASTM F2082-06 test. The superelasticity was recorded in the tension stress-strain and by the three-point bending cycles in an instrument equipped with a Hottinger force transducer and LVDT. Excellent superelastic behavior of TiNiCo wires was obtained after cold working and annealing at 400-500 °C. The body temperature activated shape memory staples were applied for fixation of mandibular condyle fractures. In experiments on the skull models, fixation of the facial fractures by using shape memory and superelastic staples were compared. The superelastic staples were used in osteosynthesis of zygomatico-maxillo-orbital fractures.

    A stainless steel bullet shaped tip has been designed for attachment to the shaft of the circular stapling device. It is useful when the shaft of this circular stapling device must transverse a viscus wall. This modification of the circular stapler has been used in vertical stapling of the stomach for morbid obesity, in low intestinal anastomoses using the side-to-end technique and in re-establishing intestinal continuity after a Hartmann procedure.

    The pursuit of fully autotrophic nitrogen removal via the anaerobic ammonium oxidation (anammox) pathway has led to an increased interest in carbon removal technologies, particularly the A-stage of the adsorption/bio-oxidation (A/B) process. The high-rate operation of the A-stage and lack of automatic process control often results in wide variations of chemical oxygen demand (COD) removal that can ultimately impact nitrogen removal in the downstream B-stage process. This study evaluated the use dissolved oxygen (DO) and mixed liquor suspended solids (MLSS) based automatic control strategies through the use of in situ on-line sensors in the A-stage of an A/B pilot study. The objective of using these control strategies was to reduce the variability of COD removal by the A-stage and thus the variability of the effluent C/N. The use of cascade DO control in the A-stage did not impact COD removal at the conditions tested in this study, likely because the bulk DO concentration (>0.5 mg/L) was maintained above the half saturation coefficient of heterotrophic organisms for DO. MLSS-based solids retention time (SRT) control, where MLSS was used as a surrogate for SRT, did not significantly reduce the effluent C/N variability but it was able to reduce COD removal variation in the A-stage by 90%.

    Response of three 150x150x450mm short reinforced concrete (RC) columns confined with different types of confining steel was investigated. Standard stirrups, strips and stapled strips, each having same cross-sectional area, were employed as confining steel around four comer column bars. Experimental work was aimed at probing into the affect of stapled strip confinement on post elastic behavior and ductility level under cyclic axial load. Ductility ratios, strength enhancement factor and core concrete strengths were compared to study the affect of confinement. Results indicate that strength enhancement in RC columns due to strip and stapled strip confinement was not remarkable as compared to stirrup confined column. It was found that as compared to stirrup confined column, stapled strip confinement enhanced the ductility of RC column by 183% and observed axial capacity of stapled strip confined columns was 41 % higher than the strip confined columns.

    1995-01-01

    A randomized, prospective study was performed to test the null hypothesis that there is no difference between the cost of stapling and suturing for skin closure of selected linear lacerations. Appropriate wounds were randomly assigned to be closed by staples or sutures. Wound lengths, skin closure times, and the number of staples or the number and types of sutures used were recorded. Costs for materials and labor were calculated. The average total cost per case was $17.69 (with suture kit) and $7.84 (without suture kit) for the staple Group compared with $21.58 for the suture Group (P = .0001 for each). It is concluded that stapling is less costly than suturing and that the advantage appears to increase as laceration length increases.

    A major objective of the project is to develop a digital automatic supervisory limitation system and validate its design for the next generation= nuclear power plant. The limitation system assures that the plant does not exceed the operating limits by regulation the plant operations through on-line monitoring the operating margins of the critical parameters. A new conceptual model of power maneuverability has been proposed for the design of the limitation system and for its validation. Also, the limitation system monitors overall operation processes throughout a nuclear power plant by implementing hierarchical communication networks. Based on the conceptual design in software of the 1 st year results, the detailed design of the limitation system has been performed during the 2 nd year with constructing a prototype digital system. The system consists of the software module for plant simulation and the hardware module for implementation of limitation system and the associated interfaces in hardware. The limitation algorithm were implemented into the microprocessor and the interfaces were realized through the I/O modules. Also, these modules are incorporated into the communication networks. The products of the project could be directly applicable to the following nuclear unit adopting the limitation system, providing the bumpless transition to the commercial design phase. And the prototype evaluation scheme will be very useful for the succeeding studies related to the digital nuclear I and C fields, such as fault-tolerance design methods, software verification and validation and response time execution of digital systems. 69 refs., 3 tabs., 44 figs.

    For over twenty years, R.H. Saunders hydraulic generating station on the St. Lawrence River near Cornwall, Ontario, Canada, has been experiencing operational and structural problems attributable to excessive concrete distortions, which required costly maintenance work and extended outages. In 1990, following diagnosis of concrete growth due to mild alkali-silica reaction as the cause of these problems, a Stage 1 Rehabilitation Plan was prepared and executed during the fall of 1992 and early 1993. The major components of the remedial plan were: (a) slot cutting at the contraction joints between Units in order to relieve cumulated stresses and allow further expansion without deforming the turbine-generators, and, (b) installation of an integrated instrumentation system to monitor closely the structural response of the first cut and to collect data required for definition and detailed planning of future slot cutting programs. This paper presents the design criteria, installation, and commissioning of this instrumentation system, as well as the operation and attributes of the Automated Data Acquisition

    Currently, the assessment of autonomy and functional ability involves clinical rating scales. However, scales are often limited in their ability to provide objective and sensitive information. By contrast, information and communication technologies may overcome these limitations by capturing more fully functional as well as cognitive disturbances associated with Alzheimer disease (AD). We investigated the quantitative assessment of autonomy in dementia patients based not only on gait analysis but also on the participant performance on instrumental activities of daily living (IADL) automatically recognized by a video event monitoring system (EMS). Three groups of participants (healthy controls, mild cognitive impairment, and AD patients) had to carry out a standardized scenario consisting of physical tasks (single and dual task) and several IADL such as preparing a pillbox or making a phone call while being recorded. After, video sensor data were processed by an EMS that automatically extracts kinematic parameters of the participants' gait and recognizes their carried out activities. These parameters were then used for the assessment of the participants' performance levels, here referred as autonomy. Autonomy assessment was approached as classification task using artificial intelligence methods that takes as input the parameters extracted by the EMS, here referred as behavioral profile. Activities were accurately recognized by the EMS with high precision. The most accurately recognized activities were "prepare medication" with 93% and "using phone" with 89% precision. The diagnostic group classifier obtained a precision of 73.46% when combining the analyses of physical tasks with IADL. In a further analysis, the created autonomy group classifier which obtained a precision of 83.67% when combining physical tasks and IADL. Results suggest that it is possible to quantitatively assess IADL functioning supported by an EMS and that even based on the extracted data the

    To determine effects of staple size, precompression time, and tissue thickness on staple shape and tissue approximation in side-to-side jejunocecal anastomosis in equine specimens. Cecum, ileum, and jejunum specimens obtained from 18 healthy horses at an abattoir. Specimens were allotted into 2 groups. Anastomoses were stapled with 4.8-or 3.8-mm staples. Precompression time was 15 seconds for both groups. Staple lines were cut into proximal, middle, and distal sections. Thickness of intestinal walls was measured with a calibrated tissue micrometer, photographs were obtained, and intestinal tissues were digested. An investigator measured staples and assessed the shape of staples on high-definition digital images. Number of optimally shaped staples and staple height were compared among sections and between groups. Use of 4.8-mm staples resulted in poor approximation of tissues in the distal sections of anastomoses. The percentage of optimally shaped staples was 538 of 551 (97.6%) and 616 of 634 (97.2%) for 4.8- and 3.8-mm staples, respectively. The percentage of optimally shaped staples did not differ significantly between groups for the same sections. There was a lower percentage of optimally shaped staples in the distal sections than in the proximal and middle sections of each group. Mean staple height did not differ significantly among sections of each group. Use of 3.8-mm staples with an adequate precompression time for jejunocecal anastomosis in horses resulted in proper staple shape. These findings could be used to improve the technique and outcome for stapled jejunocecal anastomoses in horses.

    To describe an unusual long-term complication of circular end-to-end anastomosis (CEEA) stapling in a dog. Clinical case report. An 11-year-old, female neutered, Labrador Retriever. The dog was referred for clinical signs of bowel obstruction. An enterectomy was performed 2 years before presentation using a CEEA stapling device. Palpation, plain radiographs, and ultrasound of the abdomen confirmed the presence of a mass in the bowel, causing obstruction, and requiring surgical approach. An exploratory celiotomy revealed a 5 cm mass in the jejunum, involving the site of the previous surgery. The mass was removed by enterectomy. Dissection of the mass revealed the presence of many staples at the previous enterectomy site, and a trichobezoar entangled in the exposed parts of the staples. An enterectomy was required to treat an intestinal obstruction caused by a trichobezoar entangled in a CEEA-stapled anastomosis. Development of trichobezoar and subsequent bowel obstruction should be considered an unusual but potential long-term complication of CEEA-stapled anastomosis.

    Stapled peptides have emerged as a new class of targeting molecules with high binding affinity and specificity for intracellular undruggable targets. Their ability to penetrate cell membranes is exceptionally intriguing but remains elusively and controversially discussed. To understand the effect of stapling architectures on their physiochemical properties and to aid in promoting their cell permeability, we report herein a comparative study on the physiochemical properties and cell permeability of stapled α-helical peptides with different types of crosslinks. We highlight the decisive impact of the intrinsic properties of the crosslinks on cell permeability rather than the helical contents of the peptides in model amphipathic sequences targeting estrogen receptor-coactivator interaction. We envision this finding to shed further light on the chemical optimization of stapled α-helical peptides or macrocyclic cell-penetrating peptides for enhanced cell penetration. © 2017 Wiley-VCH Verlag GmbH & Co.

    The aim of this study was to investigate the association of Brazil's staple food, rice, beans and manioc, and the incidence of type 2 diabetes mellitus type 2 (T2DM) in adults assisted by a Brazilian Family Doctor Program (FDP). The baseline information was collected on visits to 13 units of the FDP from July 2006 to December 2007 (CAMELIA Study). The units were revisited by trained researchers between July and December 2011, who reviewed medical records of all participants of the baseline. Biochemical, anthropometrical and blood pressure measurements, new diagnoses, and medical prescriptions were collected. Individuals ages ≥20 y, who were non-diabetic at baseline were included (N = 409). Food consumption was estimated using a validated semi-quantitative food frequency questionnaire. Incident of diabetes was classified according to fasting serum glucose (≥126 mg/dL), individual's use of antidiabetic drugs, and/or diagnosis of diabetes described in the medical record. Individuals who were negative at baseline and also were negative for the above conditions were classified as non-diabetics. Individuals who developed T2DM (N = 30) reported higher consumption of red meat and beans and less consumption of cassava flour, independent of the interval between visits and other potential confounding variables. The cassava flour showed a protective effect (relative risk, 0.910; 95% confidence interval, 0.842-0.982). The consumption of cassava flour, a low-cost product, could be considered in diets for the prevention and control of diabetes. The hypothesis must be investigated in cohorts from different populations and tested in randomized controlled trials. Copyright © 2014 Elsevier Inc. All rights reserved.

    Staple line leakage and bleeding are the most common problems associated with the use of surgical staplers for gastrointestinal resection and anastomotic procedures. These complications can be reduced by reinforcing the staple lines with buttressing materials. The current study reports the potential use of cholecyst-derived extracellular matrix (CEM) in non-crosslinked (NCEM) and crosslinked (XCEM) forms, and compares their mechanical performance with clinically available buttress materials [small intestinal submucosa (SIS) and bovine pericardium (BP)] in an ex vivo small intestine model.

    Staples are not considered an important source of minerals in the diet. However, because of high staple consumption, any increase in mineral concentration might well have a significant effect on human nutrition and health. The nutritional quality of staple crops (rice, cassava, wheat, maize and beans) can be improved by breeding. Studies have shown the potential to exploit the genetic variation in seed concentration of iron and other minerals without the general negative effect on yield of adding new traits. The relationship between yield and mineral concentration may be positive, particularly in mineral-deficient soil. Initial evaluations have shown that some crop varieties have high Fe, Zn and carotene in their edible portions. The next step for conventional breeding will be to study the genetics of trace mineral inheritance to determine the best selection technique. Initial investigations of the genetics for high iron in rice have indicated a complex mode of inheritance, demonstrating additive and dominant gene and environmental effects. Breeding strategies have been developed based on these genetic findings. The use of biotechnological tools, such as molecular marker-assisted selection, will significantly increase the pace and prospects of success for breeding to improve the nutritional value of staple food crops.

    2015-01-01

    A systematic review addressing reported complications of stapled hemorrhoidopexy was conducted. Articles were identified via searching OVID and MEDLINE between July 2011 and October 2013. Limitations were placed on the search criteria with articles published from 1998 to 2013 being included in this review. No language restrictions were placed on the search, however foreign language articles were not translated. Two reviewers independently screened the abstracts for relevance and their suitability for inclusion. Data extraction was conducted by both reviewers and entered and analyzed in Microsoft Excel. The search identified 784 articles and 78 of these were suitable for inclusion in the review. A total of 14,232 patients underwent a stapled hemorrhoidopexy in this review. Overall complication rates of stapled hemorrhoidopexy ranged from 3.3%-81% with 5 mortalities documented. Early and late complications were defined individually with overall data suggesting that early complications ranged from 2.3%-58.9% and late complications ranged from 2.5%-80%. Complications unique to the procedure were identified and rates recorded. Both early and late complications unique to stapled hemorrhoidopexy were identified and assessed.

    Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger retailers. In 2014, prices were measured for 15 staple foods during store visits in 140 smaller stores (corner stores, gas-marts, dollar stores, and pharmacies) in Minneapolis/St. Paul, MN and their closest supermarket. Mixed models controlling for store type were used to estimate the average price differential between: (a) smaller stores and supermarkets; (b) isolated smaller stores (>1 mile to closest supermarket) and non-isolated smaller stores; and (c) isolated smaller stores inside versus outside USDA-identified food deserts. On average, all items except white bread were 10-54% more expensive in smaller stores than in supermarkets ( p food deserts. We conclude that smaller food stores have higher prices for most staple foods compared to their closest supermarket, regardless of proximity. More research is needed to examine staple food prices in different retail spaces.

    2003-01-01

    Automatic sequences are sequences which are produced by a finite automaton. Although they are not random they may look as being random. They are complicated, in the sense of not being not ultimately periodic, they may look rather complicated, in the sense that it may not be easy to name the rule by which the sequence is generated, however there exists a rule which generates the sequence. The concept automatic sequences has special applications in algebra, number theory, finite automata and formal languages, combinatorics on words. The text deals with different aspects of automatic sequences, in particular:· a general introduction to automatic sequences· the basic (combinatorial) properties of automatic sequences· the algebraic approach to automatic sequences· geometric objects related to automatic sequences.

  12. How I do it: the stapled ileal J pouch at restorative proctocolectomy.

    LENUS (Irish Health Repository)

    Martin, S T

    2011-12-01

    Ileal pouch-anal anastomosis (IPAA) following proctocolectomy is the preferred option for patients with medically refractory ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis. However, it remains a procedure associated with morbidity and mortality. Pelvic sepsis, pouch fistulae, and anastomotic dehiscence predispose to pouch failure. We report our experience with an adaptation for the formation of the stapled ileal J pouch using the GIA™ 100 stapling device (Covidien, Mansfield, Massachusetts, USA). When creating the J pouch, we remove the bevelled plastic protector from the thin fork of the stapling device, allowing the staple line to be completed to the tip of the stapled efferent limb of the pouch, thereby minimizing potential blind ending in the efferent limb and injury to the transverse staple line.

  13. CT and MR imaging artifacts produced by stainless steel, titanium, and polymer surgical clips and staples

    To determine the effect of metal and polymer surgical clips and staples on CT and MR image quality, the authors obtained images of the implants in water and gelatin phantoms and muscle and brain tissue. Deflection angles were measured; the deflection force associated with steel devices of 1.89 T was six times that associated with titanium. Stainless steel staples produced artifacts on CT, while titanium and polymer did not. At 0.14 T, MR imaging artifacts were seen with steel but not titanium or polymer implants. At 1.89 T, distortion was caused by all stainless steel staples and the largest titanium staples, but not by polymer clips

  14. Stapled BH3 peptides against MCL-1: mechanism and design using atomistic simulations.

    Directory of Open Access Journals (Sweden)

    Thomas L Joseph

    Full Text Available Atomistic simulations of a set of stapled alpha helical peptides derived from the BH3 helix of MCL-1 (Stewart et al. (2010 Nat Chem Biol 6: 595-601 complexed to a fragment (residues 172-320 of MCL-1 revealed that the highest affinity is achieved when the staples engage the surface of MCL-1 as has also been demonstrated for p53-MDM2 (Joseph et al. (2010 Cell Cycle 9: 4560-4568; Baek et al. (2012 J Am Chem Soc 134: 103-106. Affinity is also modulated by the ability of the staples to pre-organize the peptides as helices. Molecular dynamics simulations of these stapled BH3 peptides were carried out followed by determination of the energies of interactions using MM/GBSA methods. These show that the location of the staple is a key determinant of a good binding stapled peptide from a bad binder. The good binder derives binding affinity from interactions between the hydrophobic staple and a hydrophobic patch on MCL-1. The position of the staple was varied, guiding the design of new stapled peptides with higher affinities.

  15. A stapled BIM peptide overcomes apoptotic resistance in hematologic cancers

    Cancer cells subvert the natural balance between cellular life and death, achieving immortality through pathologic enforcement of survival pathways and blockade of cell death mechanisms. Pro-apoptotic BCL-2 family proteins are frequently disarmed in relapsed and refractory cancer through genetic deletion or interaction-based neutralization by overexpressed antiapoptotic proteins, resulting in resistance to chemotherapy and radiation treatments. New pharmacologic strategies are urgently needed to overcome these formidable apoptotic blockades. We harnessed the natural killing activity of BCL-2–interacting mediator of cell death (BIM), which contains one of the most potent BH3 death domains of the BCL-2 protein family, to restore BH3-dependent cell death in resistant hematologic cancers. A hydrocarbon-stapled peptide modeled after the BIM BH3 helix broadly targeted BCL-2 family proteins with high affinity, blocked inhibitory antiapoptotic interactions, directly triggered proapoptotic activity, and induced dose-responsive and BH3 sequence–specific cell death of hematologic cancer cells. The therapeutic potential of stapled BIM BH3 was highlighted by the selective activation of cell death in the aberrant lymphoid infiltrates of mice reconstituted with BIM-deficient bone marrow and in a human AML xenograft model. Thus, we found that broad and multimodal targeting of the BCL-2 family pathway can overcome pathologic barriers to cell death. PMID:22622039

    In this study, monthly variations in biomass of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) were analysed over a 1-year period by fluorescence in situ hybridization (FISH) at the full-scale Fusina WWTP. The nitrification capacity of the plant was also monitored using periodic respirometric batch tests and by an automated on-line titrimetric instrument (TITrimetric Automated ANalyser). The percentage of nitrifying bacteria in the plant was the highest in summer and was in the range of 10-15 % of the active biomass. The maximum nitrosation rate varied in the range 2.0-4.0 mg NH4 g(-1) VSS h(-1) (0.048-0.096 kg TKN kg(-1) VSS day(-1)): values obtained by laboratory measurements and the on-line instrument were similar and significantly correlated. The activity measurements provided a valuable tool for estimating the maximum total Kjeldahl nitrogen (TKN) loading possible at the plant and provided an early warning of whether the TKN was approaching its limiting value. The FISH analysis permitted determination of the nitrifying biomass present. The main operational parameter affecting both the population dynamics and the maximum nitrosation activity was mixed liquor volatile suspended solids (MLVSS) concentration and was negatively correlated with ammonia-oxidizing bacteria (AOB) (p = 0.029) and (NOB) (p = 0.01) abundances and positively correlated with maximum nitrosation rates (p = 0.035). Increases in concentrations led to decreases in nitrifying bacteria abundance, but their nitrosation activity was higher. These results demonstrate the importance of MLVSS concentration as key factor in the development and activity of nitrifying communities in wastewater treatment plants (WWTPs). Operational data on VSS and sludge volume index (SVI) values are also presented on 11-year basis observations.

    2018-01-01

    With over 600 million people being obese, and given the scientific demonstration of the advantages of surgical treatment, bariatric surgery is on the rise. The promising long-term results in terms of weight loss, and particularly in relation to comorbidities and the control/cure rate, mean that the number of procedures performed in all countries remains high. However, the risk of potentially complex or fatal complications, though small, is present and is related to the procedures per se . This review is a guide for bariatric and/or general surgeons, offering a complete overview of the pathogenesis of anastomosis and staple line following the most common laparoscopic bariatric procedures: sleeve gastrectomy, gastric bypass, and mini-gastric bypass. The review is divided according to the procedure and the complications (leak, bleeding and stenosis), and evaluates all the factors that can potentially improve or worsen the complication rate, representing a "unicum" in the present literature on bariatric surgery.

    To verify if in large haemorrhoidal prolapse (independently from the degree) in patients with no symptoms of obstructed defaecation syndrome, the use of a stapled hemorrhoidopexy variant, comprising a double stapler haemorrhoidopexy (DSH), makes it possible to reduce the percentage of failures or relapses and to standardise an objective intraoperative parameter for the purpose of quantifying internal prolapses which can then be used as a guide in determining the type of treatment to be provided. Between June 2003 and June 2004, 353 patients were treated for haemorrhoidal prolapse. The patients suffering from large haemorrhoidal prolapse occupying more than half of the length of the anal dilator were intraoperatively selected for DSH. Eighty-three patients (23.5%) underwent a DSH. The degrees of the large haemorrhoidal prolapse intraoperatively selected for DSH were sub-divided as follows: 7.2% (second), 24% (third) and 68.6% (fourth). The follow-up period was 48 months. There were three cases (3.6%) of residual illnesses and five cases (6%) of a relapse. The following complications were recorded: urgency at <3 months (7.2%), haemostasis revisions (2.4%) and spontaneously draining anterior haematoma (1.2%). The results of the 270 haemorrhoidal prolapse (38 second degree, 159 third degree and 130 fourth degree) treated with the procedure for prolapse and haemorrhoids were: nine (3.3%) residual illness and 12 (4.44%) relapse illness. The following complications were recorded: urgency at <3 months (6.6%), haemostasis revisions (2.5%) and spontaneously draining anterior haematoma (0.7%). The intraoperative selection criterion was both efficacious and reproducible. This variant technique, which can be used in large haemorrhoidal prolapses, could allow us to further improve the quality of treatment for haemorrhoidal conditions using stapled haemorrhoidopexy, without increasing the complications.

    2012-02-03

    PURPOSE: The use of transanal stapling devices may impair continence because of digital dilatation and\\/or instrumentation. This study assessed the effect of pharmacological dilatation of the sphincter prior to stapler insertion. METHODS: A randomized, placebo-controlled, double-blinded study of 60 patients undergoing transanal stapled anastomosis was undertaken. Consenting patients were randomly assigned to receive a single intraoperative dose of topical 0.2 percent nitroglycerin (glyceryl trinitrate) ointment or nitroglycerin-free placebo. All patients were assessed preoperatively and postoperatively by clinical methods (Wexner incontinence scores and examination), anorectal manometry by a station pull-through technique, and endoanal ultrasonography. RESULTS: Intraoperative mean (+\\/-SEM) resting pressures (mmHg) were significantly reduced by nitroglycerin compared with prenitroglycerin levels (9.9 +\\/- 0.9 vs. 50.5 +\\/- 2.7; P = 0.002) or controls (56.0 +\\/- 3.2; P = 0.001). Twenty-one of the 28 controls (75 percent) but only 4 of the 32 patients in the nitroglycerin group (12.5 percent) required digital dilatation to insert the stapling instrument ( P = 0.003). Squeeze pressures were unaltered by the intervention but mean resting pressures were higher in the nitroglycerin group postoperatively (52.9 +\\/- 3.2 - 31.6 +\\/- 1.3 = 21.3 mmHg; 95 percent confidence interval, 14-27). Incontinence scores were lower in the nitroglycerin group at the 3-month (1.1 +\\/- 0.2 vs. 4.6 +\\/- 0.3; P = 0.003) and 12-month (0.9 +\\/- 0.1 vs. 4.4 +\\/- 0.3; P = 0.002) clinic visits. CONCLUSION: Preoperative nitroglycerin dilatation protects sphincter function in patients undergoing transanal stapled anastomoses.

  6. Reinforcing the staple line during laparoscopic sleeve gastrectomy: prospective randomized clinical study comparing three different techniques.

    2010-04-01

    Gastric leak and hemorrhage are the most important challenges after laparoscopic sleeve gastrectomy (LSG). In order to reduce these complications, the staple line can be reinforced by absorbable sutures or by the use of glycolide trimethylene carbonate copolymer onto the linear stapler (Gore Seamguard; W.L. Gore & Associates, Inc, Flagstaff, AZ). To our knowledge, there are no randomized studies showing the utility of staple line reinforcement during LSG. The purpose of this study was to randomly compare three techniques in LSG: no staple line reinforcement (group 1), buttressing of the staple line with Gore Seamguard (group 2), and staple line suturing (group 3). Between January 2008 and February 2009, 75 patients were prospectively and randomly enrolled in the three different techniques of handling the staple line during LSG. The patient groups were similar (NS). Mean operative time to perform the stomach sectioning was 15.9 +/- 5.9 min (group 1), 20.8 +/- 8.1 min (group 2), and 30.8 +/- 10.1 min (group 3) (p Gore Seamguard statistically reduces blood loss during stomach sectioning as well as overall blood loss. No staple line reinforcement statistically decreases the time to perform stomach sectioning and the total operative time. No significant difference is evidenced in terms of postoperative leak between the three techniques of LSG.

    2018-01-01

    Varieties of intraoperative methods such as oversewing of staple lines or other reinforcement products are used for preventing the laparoscopic vertical sleeve gastrectomy (LSG) complications. The aim of this study is to evaluate the complication rates of the gastric stapling alone versus stapling with oversewing invagination of the staple line in the LSG. This is a single-center randomized study, Patients were randomized to two groups, 200 patients underwent LSG without reinforcement of the staple line and 200 patients underwent LSG with oversewing of the staple line. All patients were followed up for 1 year. The data collected prospectively for statistical analysis included demographics, BMI, preoperative comorbidities, operative time, complications, and hospital stay. The overall mean operative age was 33.7 ± 9.4 years and mean BMI was 42.4 ± 4.3 kg/m 2 . Patient baseline characteristics (age, gender, weight, and BMI) and comorbidities were generally a nonsignificant different between the treatment arms. Surgical time was shorter in patients of the nonreinforced group (44.3 ± vs 51.3 ± 4.3 min; p < 0.01) with lower %EWL (73 ± 13.8 vs 80.7 ± 13.6%, p < 0.01). One patient in the nonreinforced group was complicated by gastric leak. The staple-line bleeding rate was significantly lower in patients underwent oversewing of the staple line during LSG (p < 0.05). Oversewing of the staple line during LSG is a nonexpansive and easy method to decrease the incidence and severity of the postoperative bleeding. However, it is time-consuming and should be performed by experienced surgeons to avoid the complications which may occur secondary to the seroserotomy suturing.

    Full Text Available Objective. The objective of the study was to assess the change in quality of life (QOL of patients undergoing stapled hemorrhoidopexy (SH using WHO Quality of Life-BREF (WHOQOL-BREF questionnaire. Methods. The study sample comprised patients with symptomatic II, III, and IV degree hemorrhoids, undergoing SH. The patients were asked to complete WHOQOL-BREF questionnaire before and one month following the surgery. Result. There were 20 patients in the study group. The postoperative pain score measured by visual analogue scale at six hours postoperatively was at 24 hours. The items in the WHOQOL-BREF had high-internal consistency or reliability as shown by high Cronbach's alpha coefficient which was 0.82 and 0.90 for pre- and postoperative questionnaires. There was significant improvement in the overall perception of QOL and health, and in physical and psychological domains. There was modest improvement in environmental domain, while no change was noted in social domain. Conclusion. SH improved the quality of life of patients treated for hemorrhoids.

  9. Local Staple Food Price Indices in the Age of Biofuels

    2012-01-01

    In many poor, food insecure regions, agriculture is a primary source of income and farmers are reliant both on their own production and on purchasing food in the market to feed their families. Large local food price increases over a short time period can be indicative of a deteriorating food security situation and may be the consequence of weather-related food production declines, Dr can simply be the result of price transmission from the international commodity market. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets far from the places where the chronically food insecure live. A much better understanding of how local staple food prices in isolated regions such as West Africa that grow most of the food they eat to better understand the impact of global commodity market transformations on sensitive communities at the margin. This information will also enable improved strategies for these farmers who are extraordinarily sensitive to climate change impacts on agricultural growing conditions.

    Nicholas Alexander Russell

    2015-12-01

    Full Text Available While the Lapidus procedure is a widely accepted technique for treatment of hallux valgus, the optimal fixation method to maintain joint stability remains controversial. The purpose of this study was to evaluate the biomechanical properties of new Shape Memory Alloy staples arranged in different configurations in a repeatable 1st Tarsometatarsal arthrodesis model. Ten sawbones models of the whole foot (n=5 per group were reconstructed using a single dorsal staple or two staples in a delta configuration. Each construct was mechanically tested in dorsal four-point bending, medial four-point bending, dorsal three-point bending and plantar cantilever bending with the staples activated at 37°C. The peak load, stiffness and plantar gapping were determined for each test. Pressure sensors were used to measure the contact force and area of the joint footprint in each group. There was a significant (p < 0.05 increase in peak load in the two staple constructs compared to the single staple constructs for all testing modalities. Stiffness also increased significantly in all tests except dorsal four-point bending. Pressure sensor readings showed a significantly higher contact force at time zero and contact area following loading in the two staple constructs (p < 0.05. Both groups completely recovered any plantar gapping following unloading and restored their initial contact footprint. The biomechanical integrity and repeatability of the models was demonstrated with no construct failures due to hardware or model breakdown. Shape memory alloy staples provide fixation with the ability to dynamically apply and maintain compression across a simulated arthrodesis following a range of loading conditions.

    Full Text Available With a population increasing rapidly and agricultural yields almost stagnant over the years, access to food is a major challenge in Burkina Faso. This study investigates households demand for staple cereal commodities in Burkina Faso, using data from the 2009-2010 Integrated Household Living Condition Survey. A complete almost ideal demand system (AIDS model is estimated taking into account demographics and zero consumption. Results show that maize, millet and sorghum are necessities while rice is considered a superior cereal commodity. Demand for maize, millet and sorghum are less price elastic than rice and these results are consistent for most households except for wealthy, educated households living in urban areas where rice becomes a necessity. The analysis of the evolution of cereal prices shows an overall increase leaving many people in food insecurity and the country in political instability. Therefore, the country must adopt agricultural reforms to boost production and productivity by exploiting unfarmed land, building more storage facilities, roads and rural infrastructure, using improved seeds and more fertilizer, and installing irrigation systems.

    All-hydrocarbon stapled peptides make up a promising class of protein-protein interaction regulators; their potential therapeutic benefit arises because they have a high binding affinity and specificity for intracellular molecules. The cell permeation efficacy of these peptides is a critical determinant of their bioactivity. However, the factors that determine their cellular uptake remain an active area of research. In this study, we evaluated the effect of stapled (or cross-linked) formation on the cellular uptake of six known all-hydrocarbon stapled peptides. We found that the rate of cellular uptake of unstapled peptides (i.e., those bearing olefinic non-natural amino acids that are not subjected to olefin metathesis) was higher than that for the corresponding stapled peptides. Additionally, the insertion of these olefinic non-natural amino acids into peptide sequences significantly increased their rate of cellular uptake. According to the high-performance liquid chromatography retention times, the overall hydrophobicity of unstapled peptides was greater than that of stapled peptides, followed by that of the original peptides without olefinic non-natural amino acids. There was not a close correlation between helical content and the rate of cellular uptake of these peptides. Therefore, the increase in overall hydrophobicity resulting from the introduction of non-natural amino acids, rather than the structural stabilization resulting from staple formation, is the key driver promoting cellular uptake. Macropinocytosis, a form of fluid-phase endocytosis, was involved in the cellular uptake of all six peptides.

    To compare polypropylene suture and skin staples for securing mesh in Lichtenstein inguinal hernioplasty in terms of mean operating time and postoperative pain. Randomized clinical trial. Surgical Ward, Combined Military Hospital, Kharian, from August 2011 to February 2012. All individuals fulfilling inclusion criteria underwent elective Lichtenstein inguinal hernioplasty as admitted patients, under spinal anaesthesia and with aseptic measures. In group 1, during the operation, mesh fixation was done with 2/0 polypropylene suture and skin was closed with subcuticular 2/0 polypropylene suture whereas in group 2, the anchorage of mesh was done with skin staples and skin was closed with staples from the same stapler. Mean operative time and postoperative pain, assessed on a visual analog score, were compared between the groups. The overall postoperative pain was lower (p = 0.026) when staples were used to anchor mesh. Moreover, operative time was also lower (37.42 ± 2.69 minutes) in staple group versus (42.44 ± 2.55 minutes in polypropylene group). Mean operating time and postoperative pain is less in securing mesh with skin staples as compared to polypropylene suture in Lichtenstein inguinal hernioplasty.

    A spatially representative statewide survey was conducted in Rajasthan, India to assess household coverage of atta wheat flour, edible oil, and salt. An even distribution of primary sampling units were selected based on their proximity to centroids on a hexagonal grid laid over the survey area. A sample of n = 18 households from each of m = 252 primary sampling units PSUs was taken. Demographic data on all members of these households were collected, and a broader dataset was collected about a single caregiver and a child in the first 2 years of life. Data were collected on demographic and socioeconomic status; education; housing conditions; recent infant and child mortality; water, sanitation, and hygiene practices; food security; child health; infant and young child feeding practices; maternal dietary diversity; coverage of fortified staples; and maternal and child anthropometry. Data were collected from 4,627 households and the same number of caregiver/child pairs. Atta wheat flour was widely consumed across the state (83%); however, only about 7% of the atta wheat flour was classified as fortifiable, and only about 6% was actually fortified (mostly inadequately). For oil, almost 90% of edible oil consumed by households in the survey was classified as fortifiable, but only about 24% was fortified. For salt, coverage was high, with almost 85% of households using fortified salt and 66% of households using adequately fortified salt. Iodized salt coverage was also high; however, rural and poor population groups were less likely to be reached by the intervention. Voluntary fortification of atta wheat flour and edible oil lacked sufficient industry consolidation to cover significant portions of the population. It is crucial that appropriate delivery channels are utilized to effectively deliver essential micronutrients to at-risk population groups. Government distribution systems are likely the best means to accomplish this goal.

    With the increase in agricultural demand, reducing greenhouse gas (GHG) emissions is a vital challenge in mitigating climate change. Potato staple food strategy in China introduced by Ministry of Agriculture in 2015 is to gradually adjust staple food structure, which provides an opportunity to meet with the challenge. Apart from staple food structure, difference on energy, material input, geography, and crop management are essential to determine agriculture's contribution to climate change. In this study, we conduct a life cycle analysis of four staple foods in China, namely rice, wheat, maize, and potato, to develop crop-specific estimates of GHG emissions and GHG intensity by using `Production intensity' (carbon dioxide equivalent emissions per kilocalorie produced), to help us understand potential synergies and frictions between food producing and climate mitigation. Data used in this study is on city / province levels if city level is unavailable in 2015. First, we evaluate GHG reductions due to transition of staple food structure in China. Staple food GHG emissions in China are 546.90 Tg CO2e yr-1 in 2015, with 47.6%, 21.9%, 27.3% and 3.2% from rice, wheat, maize and potato. Mean production intensity of staple food is 0.45 Mg CO2e M kcal-1 in 2015. Maize leads the intensity with 0.77 Mg CO2e M kcal-1, followed by rice (0.49 Mg CO2e M kcal-1), wheat (0.28 Mg CO2e M kcal-1) and potato (0.24 Mg CO2e M kcal-1). After staple food structure adjustment, 25 Tg CO2e yr-1 (4.2%) reduction will be accomplished in 2020 without any crop management improvement. Further reduction (33.3% - 40.4%) could be achieved with crop management improvement. In addition, because of staple food structure switching, native rice production will decline, which might lead to more export from countries with higher production intensity. Estimated emission leakage from rice import is 30.10 Tg CO2e yr-1, exceeds emission reduction in native China. Therefore, potato staple food strategy could

    The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. Recently, over-sewing has been proposed as a cost-effective and helpful method for reinforcing the staple line. The purpose of this study was to report our initial experience with LSG comparing over-sewing over the entire staple line with the upper-third staple line. All obese patients seen at Negrar Sacro Cuore, Don Calabria Hospital were entered into our prospective database and were retrospectively evaluated. Complications (divided as major complications: leaks and bleeding; and minor complications: dysphagia, esophagitis, and reflux disease) and reoperations were recorded for all patients. Complications were graded according to the Clavien classification system. From February 2015 to March 2016, 30 patients underwent LSG. Patients were divided in two groups according to over-sewing: Group A-over-sewing over the entire staple line; and Group B upper-third over-sewing. Mean total operative time was longer in Group A-90 minutes-compared with 85 minutes in Group B. In regard to minor complications, we reported one esophagitis and two cases of dysphagia in Group B and one dysphagia in Group A. Gastroesophageal reflux was higher in Group B than in Group A (3 vs. 1, p=0.149). Three major complications were observed (10%): two bleeding and one hematoma in Group B and no major complications occurred in Group A. All major complications were conservatively treated. No leaks were reported in both groups. No mortality was observed. Over-sewing of the staple line was associated with fewer leaks but no conclusions can be drawn regarding the effects of over-sewing on staple line bleedings. Before standardizing surgical techniques further, trials are necessary to improve our knowledge about over-sewing in LSG.

    Purpose. During radiofrequency ablation (RFA), there is a risk that the multitined expandable electrode will come into contact with one of the surgical staples used to treat local recurrence after surgical operations. Our objective was to evaluate whether a surgical staple would influence the RFA of egg white using a multitined expandable electrode. Methods. Multitined expandable electrodes, LeVeen needles (expandable diameter 3.0 cm), were sunk into an egg white bath with (a) no surgical staple, (b) a surgical staple touching one of the tines, or (c) a surgical staple touching two of the tines simultaneously. By connecting the LeVeen needle and copper plate at the bottom of the bath, RFA was then performed on the egg whites as a substitute for human tissue. Ten egg white baths were ablated under each of conditions (a), (b), and (c), for a total of 30 sets of coagulated egg white. Results. There was no significant difference in the time from the power-on to the roll-off (i.e., the completion and shutting off of the electric circuit) or in the maximum diameter of the thermal lesion between conditions (a) and (b) or (a) and (c). However, the minimum diameter of the thermal lesion was significantly smaller in (c) compared with (a) (p < 0.01). Conclusions. Surgical staples have the capacity to interfere with the electromagnetic field and decrease the minimum diameter of the thermal lesion in the event that a staple touches two of the tines of a multitined expandable electrode during RFA. Although the difference might be small enough to be neglected under many clinical circumstances, we recommend that, if possible, the tines not be expanded near metallic material

    The study aim was to analyse the safety and feasibility of laparoscopic intersphincteric resection with stapled coloanal anastomosis for low rectal cancer. Between March 2009 and August 2010, 22 patients underwent laparoscopic intersphincteric resection with a stapled coloanal anastomosis without a diverting ileostomy. The results were compared retrospectively with hand-sewn coloanal anastomoses performed between January 2001 and May 2009, which included 55 open and 38 laparoscopic intersphincteric resections. The morbidity comparison only included data relevant to the anastomosis. Function was compared using the Saito function questionnaire and the Wexner score and only involved data relevant to the laparoscopy. The anastomotic complication rates were similar for fistula, bleeding and neorectal mucosal prolapse (P = 0.526, P = 0.653 and P = 0.411, respectively). Anastomotic leakage and stricture formation of the stapled coloanal anastomosis were significantly lower than those of the hand-sewn coloanal anastomosis (P = 0.037 and P = 0.028, respectively). There were no significant differences in the Saito function questionnaire and the Wexner score between the stapled and hand-sewn coloanal anastomotic groups (all P > 0.05). Laparoscopic intersphincteric resection with a stapled coloanal anastomosis is technically feasible and is less likely to result in anastomotic leakage and stricture formation than a hand-sewn anastomosis.

Experimental specimens under withdrawal load test of face and edge consisted of two principal structural members, main member and a secondary member which were joined together by one staple. The results showed that joint member, penetration deeps and adhesive significantly influence on the withdrawal resistance. Staple withdrawal resistance in the face was higher than that in the edge. Staple holding resistance increased with the increase of penetration deep and the withdrawal resistance of joints fabricated by adhesive was higher than those without adhesive. The joints made by oriented strand lumber exhibited better performance than other two members and joints made with poplar wood had higher resistance than plywood joints. The highest face (2326N and edge (1265N withdrawal resistances were obtained from joints prepared from oriented strand lumber with adhesive and17mm penetration deeps.

    To determine the effect of bovine pericardium strip (BPS) reinforcement of the circular stapler on the gastrojejunostomy leak rates and staple line failure after laparoscopic Roux-en-Y gastric bypass (LRYGB) at a university hospital in the United States. Gastrojejunostomy leak after LRYGB is a devastating complication. Various techniques, including buttressing the gastrojejunostomy staple line with biomaterial, have been used in an effort to minimize leaks. A total of 350 consecutive patients underwent LRYGB without staple line buttressing. After this initial experience, BPS reinforcement of the gastrojejunostomy was conducted in 81 consecutive patients. BPS reinforcement was not used for the final 69 consecutive patients in this 500 patient series. Circular staple line failures (intraoperative immediate and complete failure of the anastomosis) and leaks were evaluated retrospectively. Three leaks (and no intraoperative staple line failures) occurred in 419 patients without BPS buttressing, all in the first 100 cases of our experience, and 3 leaks and an anastomotic staple line failure occurred in the 81 patients with BPS buttressing (.7% versus 4.9%, P = .02). The body mass index and other potential leak risk factors did not differ between the 2 groups. In our experience, buttressing of the circular staple line with BPS during LRYGB was associated with an increased staple line adverse event rate. BPS buttressing of the gastrointestinal circular staple lines should be used with caution. 2010 American Society for Metabolic and Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

    To compare the outcome of hand sewing and stapling for anastomotic leakage after esophagectomy. A rigorous study protocol was established according to the recommendations of the Cochrane Collaboration. An electronic database search, hand search, and reference search were used to retrieve all randomized controlled trials that compared hand-sewn and mechanical esophagogastric anastomoses. This study included 15 randomized controlled trials with a total of 2337 patients. The results revealed that there was no significant difference in the incidence of anastomotic leakage between the methods [relative risk (RR) = 0.77, 95% confidence interval (CI): 0.57-1.04; P = 0.09], but a subgroup analysis yielded a significant difference for the sutured layer and year of publication (Ps sewing. End-to-side stapling increases the risk of anastomotic strictures, but side-to-side stapling decreases the risk.

    This prospective clinical study evaluated the use, complications, and clinical and ultrasonographic follow-ups of end-to-end intestinal anastomoses with skin staples in naturally occurring diseases in canine small and large intestines. Intestinal anastomoses were performed in 14 dogs and pre-, peri-, and postoperative data were recorded. Postoperative clinical and ultrasound evaluations were performed at regular intervals for 1 year. The mean time taken to construct the anastomosis was 5 min. There were no intraoperative complications. Hemorrhage and colonic stricture were the main postoperative complications. Staple loss occurred in 2 cases. Absence of wall layering and focal wall thickening were observed in all cases at each ultrasonographic follow-up. Hyperechoic fat was observed in all but 1 of the cases at month 1. Nine dogs were alive with normal digestive function at the end of the study. The skin stapler technique enabled rapid construction of consistent anastomoses with inexpensive stapling material.

    Staple food crops, in particular cereal grains, are poor sources of key mineral nutrients. As a result, the world's poorest people, generally those subsisting on a monotonous cereal diet, are also those most vulnerable to mineral deficiency diseases. Various strategies have been proposed to deal with micronutrient deficiencies including the provision of mineral supplements, the fortification of processed food, the biofortification of crop plants at source with mineral-rich fertilizers and the implementation of breeding programs and genetic engineering approaches to generate mineral-rich varieties of staple crops. This review provides a critical comparison of the strategies that have been developed to address deficiencies in five key mineral nutrients-iodine, iron, zinc, calcium and selenium-and discusses the most recent advances in genetic engineering to increase mineral levels and bioavailability in our most important staple food crops.

There were 24 women and 3 men, with a mean age of 61.2 years. Two memory compression staples were used at right angles to each other to achieve compression at the fusion site. Postoperatively, patients were allowed full weightbearing in a rigid-soled shoe. Subjective assessment was performed with a standard questionnaire, which included questions regarding level of pain, ambulation, and patient satisfaction. Objective assessment was performed by a clinical and included a radiographic examination. There was a postoperative reduction in the pain score from 4.6 to 1.6 (P memory compression staples for the internal fixation of first metatarsophalangeal joint arthrodesis. The implant is low profile, and postoperative cast immobilization is not required. The use of this device has a predictable success rate comparable to previously reported methods.

    Introduction Anastomotic leak is one of the main causes of morbidity following esophageal resection for carcinoma of the esophagus and gastroesophageal junction. We compared hand sewn and stapled cervical esophagogastric anastomotic techniques in terms of postoperative complications. Methods All patients who underwent esophagectomy with cervical esophagogastric anastomosis at a single academic center from 2004 to 2014 were included in the study. Both early and late complications were analyzed. Results 153 patients underwent resection for carcinoma of the esophagus and gastroesophageal junction. Of these 140 patients had esophagectomy with cervical esophagogastric anastomosis. 66 patients underwent a hand sewn anastomosis and 74 patients had a side-to-side stapled anastomosis fashioned. Both groups were comparable with respect to preoperative characteristics. There was no difference in the operative blood loss and T and N stage of the disease. The overall morbidity and mortality was 32.8% and 6.4%, respectively. Overall leak rate was 17%. There was no difference in the leak rates among two groups (12 in the hand-sewn group & 12 in the Stapled stapled group; p = 0.82). The rate of anastomotic stricture was significantly higher for the hand sewn group (16.1% vs 4.3%; p = 0.03) at median follow up of 30 months. Conclusion Both hand sewn and stapled anastomotic techniques are equally effective way of performing a cervical esophagogastric anastomosis. However, patients having anastomotic leak develop anastomotic stricture more often in those having hand-sewn anastomosis compared to stapled anastomosis. PMID:27222711

    To determine the frequency of dehiscence of hand-sutured and stapled intestinal anastomoses in the dog and compare the surgery duration for the methods of anastomosis. Historical cohort study. Two hundred fourteen client-owned dogs undergoing hand-sutured (n = 142) or stapled (n = 72) intestinal anastomoses. Medical records from 5 referral institutions were searched for dogs undergoing intestinal resection and anastomosis between March 2006 and February 2014. Demographic data, presence of septic peritonitis before surgery, surgical technique (hand-sutured or stapled), surgery duration, surgeon (resident versus faculty member), indication for surgical intervention, anatomic location of resection and anastomosis, and if dehiscence was noted postoperatively were retrieved. Estimated frequencies were summarized and presented as proportions and 95% confidence intervals (CI) and continuous outcomes as mean (95% CI). Comparisons were made across methods of anastomosis. Overall, 29/205 dogs (0.14, 95% CI 0.10-00.19) had dehiscence, including 21/134 dogs (0.16, 0.11-0.23) undergoing hand-sutured anastomosis and 8/71 dogs (0.11, 0.06-0.21) undergoing stapled anastomosis. There was no significant difference in the frequency of dehiscence across anastomosis methods (χ(2), P = .389). The mean (95% CI) surgery duration of 140 minutes (132-147) for hand- sutured anastomoses and 108 minutes (99-119) for stapled anastomoses was significantly different (t-test, P dogs but surgery duration is significantly reduced by the use of staples for intestinal closure. © Copyright 2015 by The American College of Veterinary Surgeons.

    Prolonged air leak remains as one of the most common complications after surgery for bullous lung disease. Reinforcement of the staple line with either prosthetic material or bovine pericardial strips has been advocated to avoid this problem. We used the patients' own parietal pleural layer to cover the staple lines to prevent air leak and subsequently assessed the comparative results. A total of 22 patients underwent thoracotomy for bullous lung disease, mainly due to lobe-dominance bullae combined with emphysema, between November 2006 and November 2008. A case-control study was set from the surgical data of patients who were operated on using stapling devices without any buttressing material (group I=12) and were compared with the group of patients who were operated on using staplers buttressed with an autologous pleural layer (group II=10). Patient characteristics, chest-tube removal time and length of hospital stay were prospectively recorded in group II. The outcomes of the two groups were analysed based on postoperative complications, chest-tube removal time and postoperative length of hospital stay. There was no statistically significant difference between both the groups in preoperative characteristics including age, sex, co-morbid factors, and respiratory functions, heterogeneity of emphysema, intra-operative adhesion density and length of staple line. However, the chest tube was removed significantly earlier in patients whose bullae were resected by stapling devices buttressed with autologous-parietal pleura (p=0.04). Autologous pleural reinforcement of the staple line in surgery for bullous lung disease is a safe, effective and cost-free procedure that precipitates the early removal of the chest tube.

    Hemi-epiphysiodesis should always be considered as an effective treatment to correct axial limb deformity in children. The use of the 8-plate as opposed to conventional staples provides firm fixation to both sides of the physis, acting mainly upon the epiphyseal growth site of the implant insertion. The aim of our study is to compare the effectiveness of both devices for performing angular corrections. Seventeen rabbits of 18 months of age were treated with an 8-plate in the distal femur and a staple in the contralateral femur. Eight weeks later, the level of deformity produced by each device was evaluated both radiographically and histologically. Axial deformity: the staples produced an average deviation of 48.1 degrees, and the 8-plate produced an average deviation of 49.1 degrees (P=0.44). Final longitudinal growth of the femurs: we recorded an average of 83.17 degrees for the staples and 85.7 degrees for the 8-plate. Histologic analysis: no significant difference was observed between both femurs of the same specimen; however, a slight difference was recorded when analyzing the results of different animals. Correction was achieved in less time when using conventional staples. The long-term effectiveness of both epiphysiodesis is similar. Longitudinal growth inhibition is lower when using 8-plate. Although both methods are effective in stopping the growth, the 8-plate has better grasp to the bone or epiphyseal cartilage avoiding extrusion in small children. The correction is faster using a staple and that is the reason why we prefer its usage in patients with little remnant growth.

    Circular stapled transanal hemorrhoidopexy (STH) was first introduced by A. Longo for the correction of internal mucosal prolapse and obstructed defecation and in 1998, was proposed as alternative to conventional excisional hemorrhoidectomy. More recently, stapled transanal rectal resection (STARR) has gradually gained popularity, as the Longo procedure, in the treatment of hemorrhoids. The aim of our study was to evaluate the usefulness of STARR as alternative to STH in patients with grade III (n=218, 68.1%) and IV (n=102, 31.9%) hemorrhoids. A group of 320 consecutive patients (median age=51 years; range=16-85) underwent STH (n=281) or STARR (n=39) procedure. The rate of postoperative bleeding (53.8% vs. 74.4%, pSTH group. In conclusion, according to our preliminary results, the STARR procedure leads to a lower incidence of complications and recurrences and should be considered for patients with grade III or IV hemorrhoids previously selected for stapled hemorrhoidectomy, as a promising alternative to STH.

    Full Text Available Background and Aims. Endoscopic fundoplication is an emerging technique for the treatment of gastroesophageal reflux disease (GERD. The aim of this study is to determine the ideal position of the staples in relation to gastroesophageal junction (GEJ. Methods. Ten endoscopic fundoplication procedures were performed in each group using fresh ex vivo porcine stomachs: Group A: 2 staples each at 3 cm above the GEJ and 180° apart; Group B: 2 staples at 3 cm and 90° apart; Group C: 2 staples at 4 cm and 180° apart; Group D: 3 staples at 3 cm with 90° between each staple (180° total. After the procedure, the stomach was gradually filled with water. Gastric yield pressure (GYP was determined by detection of reflux of the water in esophagus or by rupture of staples. Results. Mean increase of GYPs (±SD after the procedure was as follows: Group A: 16.9±8.7; Group B: 8.1±7.9; Group C: 12.2±9.4; Group D: 22.7±13.3. GYP in Group A and Group D was higher than Group B (p=0.03 and p=0.01, resp.. Conclusions. We recommend the placement of 3 staples at 3 cm distance from the GEJ, which resulted in the highest increase of GYP.

  19. Automatic personnel contamination monitor

    1978-01-01

    United Nuclear Industries, Inc. (UNI) has developed an automatic personnel contamination monitor (APCM), which uniquely combines the design features of both portal and hand and shoe monitors. In addition, this prototype system also has a number of new features, including: micro computer control and readout, nineteen large area gas flow detectors, real-time background compensation, self-checking for system failures, and card reader identification and control. UNI's experience in operating the Hanford N Reactor, located in Richland, Washington, has shown the necessity of automatically monitoring plant personnel for contamination after they have passed through the procedurally controlled radiation zones. This final check ensures that each radiation zone worker has been properly checked before leaving company controlled boundaries. Investigation of the commercially available portal and hand and shoe monitors indicated that they did not have the sensitivity or sophistication required for UNI's application, therefore, a development program was initiated, resulting in the subject monitor. Field testing shows good sensitivity to personnel contamination with the majority of alarms showing contaminants on clothing, face and head areas. In general, the APCM has sensitivity comparable to portal survey instrumentation. The inherit stand-in, walk-on feature of the APCM not only makes it easy to use, but makes it difficult to bypass.

    1996-07-01

    In the past decade, great technological progress has been made in telemaintenance of mainframe and mini computers. As hardware technology is now available at an acceptable cost, computer aided trouble-shooting can be adapted to laboratory instrumentation in order to significantly improve repair time, avoid instrument downtime by taking advantage of predictive methods, and provide general diagnostic assistance. Depending on the size of the instrument, the telemaintenance facility can be dedicated to a single instrument or alternatively a telemaintenance server can manage multiple distributed small instruments through a Local Area Network. As complex failures can occur, the local diagnosis capabilities may be exceeded and automatic dialing for connection to computerized Remote Maintenance Centers is needed. The main advantages of such a centre, as compared to local diagnosis systems, are the increased access to more information and experience of failures from instrument installations, and consequently the provision of training data updates for Artificial Neural Networks and Knowledge Based Systems in general. When an abnormal situation is detected or anticipated by a diagnosis module, an automatic alert is given to the user, local diagnosis is activated, and for simple solutions, instructions are given to the operator. In the last resort, a human expert can be alerted who, with remote control tools, can attend to the failures. For both local and remote trouble-shooting, the data provided by the instrument and connected workstation is of paramount importance for the efficiency and accuracy of the diagnosis. Equally, the importance of standardization of telemaintenance communication protocols is addressed.

    Different fixation techniques have been described in the literature for isolated subtalar arthrodesis (ISA). The purpose of this study was to compare the fusion rate and clinical outcome of ISA using cannulated compression screws or compression staples. Thirty-three patients (33 feet) underwent ISA using screw (17 feet) or staples (16 feet) fixation. Patients were followed for 42.7 ± 16.4 months (range, 24.5-84.3 months). The subtalar fusion was assessed radiographically and clinically. Clinical outcome measures included the visual analog scale (VAS) for pain and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. The average pain score decreased significantly from 6.4 ± 1.1 (range, 5-9) to 0.8 ± 1.3 (range, 0-4) (P screws group, the average AOFAS hindfoot score increased significantly from 54.6 ± 8.8 (range, 37-67) preoperatively to 86.1 ± 7.1 (range, 71-91) postoperatively (P screw fixation was significantly higher than in the staples fixation group (P = .005). There were 4 cases of nonunion at the site of subtalar arthrodesis (2 from screws group, 2 from staples group). The complication rate was comparable in both groups. The fusion rate was comparable in both groups, while the postoperative functional outcome was significantly better in the screw fixation group.

    To compare 2 graduated compression staples (Tri-Staple™, Covidien, Norwalk, CT) and standard staples (Endo GIA™, Covidien) for lung biopsy in dogs. Ex vivo experimental study, randomized, unblocked. Lung lobes (n = 18) from 4 canine cadavers. Eighteen lung lobes were harvested from 4 dogs immediately after euthanasia and randomized to 1 of 3 staples (n = 6 per stapler type). Each lung lobe was intubated and maintained inflated at 10 cmH2O. A biopsy of the periphery of each lung lobe was taken approximately 3 cm from the edge with a stapling device; the Tri-Staple™ medium/thick (TST), Tri-Staple™ vascular/medium (TSV), and Endo GIA™ 45-2.5 (EG). Each lobe was inflated to a maximum of 45 cmH2O of water to determine the pressure at which air leakage occurred (leak pressure). The mean (95% confidence interval) leak pressure was 38.0 cmH2O (33.1-42.9) for EG, 29.2 (24.3-34.0) for TSV, and 26.0 (21.1-30.9) for TST. The mean leak pressure was significantly higher for EG than TSV (P = .016) and for EG than TST (P = .002), but was not different between TSV and TST (P = .344). One TSV leaked at 20 cmH2O and 1 TST leaked at 17 cmH2O. The surface area of the biopsy samples was not significantly different for staple types (P = .183). Both TST and TSV leaked at significantly lower airway pressures than EG and may not be suitable for canine lung biopsy as some specimens leaked at pressures of 20 cmH2O or less. © Copyright 2015 by The American College of Veterinary Surgeons.

    This alkaloid automated removal machine was developed at Instrumentation Laboratory, Universiti Sultan Zainal Abidin Malaysia that purposely for removing the alkaloid toxicity from Dioscorea hispida (DH) tuber. It is a poisonous plant where scientific study has shown that its tubers contain toxic alkaloid constituents, dioscorine. The tubers can only be consumed after it poisonous is removed. In this experiment, the tubers are needed to blend as powder form before inserting into machine basket. The user is need to push the START button on machine controller for switching the water pump ON by then creating turbulence wave of water in machine tank. The water will stop automatically by triggering the outlet solenoid valve. The powders of tubers are washed for 10 minutes while 1 liter of contaminated water due toxin mixture is flowing out. At this time, the controller will automatically triggered inlet solenoid valve and the new water will flow in machine tank until achieve the desire level that which determined by ultra sonic sensor. This process will repeated for 7 h and the positive result is achieved and shows it significant according to the several parameters of biological character ofpH, temperature, dissolve oxygen, turbidity, conductivity and fish survival rate or time. From that parameter, it also shows the positive result which is near or same with control water and assuming was made that the toxin is fully removed when the pH of DH powder is near with control water. For control water, the pH is about 5.3 while water from this experiment process is 6.0 and before run the machine the pH of contaminated water is about 3.8 which are too acid. This automated machine can save time for removing toxicity from DH compared with a traditional method while less observation of the user.

    Laparoscopic total gastrectomy is not widely performed because of the difficulty of esophagojejunal reconstruction. This study analyzed complication rates of two different methods for reconstruction by a circular stapler after totally laparoscopic total gastrectomy (TLTG). Between 2010 and 2014, clinical data of 19 patients who underwent TLTG for gastric adenocarcinoma were collected retrospectively. There were two methods to fix the anvil of a circular stapler into the distal esophagus: In the single-stapling technique (SST) group, Endo-PSI(II) was used for purse-suturing on the distal esophagus for reconstruction, and in the hemi-double-stapling technique (hemi-DST) group, the esophagus was cut by linear stapler with the entry hole of the anvil shaft opened after inserting the anvil tail. In both groups, surgical procedures were the same, except for the reconstruction. All TLTGs were performed securely without mortality. Intracorporeal laparoscopic esophagojejunal anastomosis was performed successfully for all the patients. In the hemi-DST group, four patients experienced anastomotic stenosis, three of whom required endoscopic balloon dilation. In contrast, no stenosis was seen in the SST group (p = 0.033). Anastomosis with SST is preferred to that with hemi-DST to minimize postoperative complications.

    An 8-year-old, female domestic shorthair cat was presented with a ventral abdominal subcutaneous mass. A radiograph showed that the center of the mass contained what appeared to be steel sutures, presumed to be from an ovariohysterectomy performed 7 years earlier. The excised mass was irregular and contained numerous pockets filled with friable necrotic material and hemorrhages that were dissected by fibrous connective tissue bands. Multiple tangled and fragmented pieces of steel staples were deeply embedded within the mass. Histologically, the mass was non-encapsulated, densely cellular, and infiltrative. Neoplastic cells lined caverns and channels and were factor VIII-positive by immunohistochemistry. The neoplastic cells were oval to round with granular cytoplasm and vesicular nucleus and exhibited moderate cellular and nuclear pleomorphism. A diagnosis of subcutaneous hemangiosarcoma was made. To our knowledge, this is the first report of foreign body associated hemangiosarcoma and the first case of steel staple associated neoplasm in domestic animals.

    Laparoscopic sleeve gastrectomy (LSG) is a bariatric procedure with very good long-term weight-reducing and metabolic effects. Here we report 6 years' experience with LSG performed in morbidly obese patients by one surgical team focusing on the impact of the degree of sleeve restriction and safety of the procedure without over-sewing the staple line. From 2006 to 2012, 207 morbid obese patients with average age of 43.4 years and average body mass index 44.9 kg/m(2) underwent LSG without over-sewing the staple line. The complete 5- and 3-year follow-up is recorded in 59 and 117 patients with prospective data collection at 3, 6, 9, 12, 18, 24, 36, 42 and 60 months after LSG. Group 1 patients operated in 2006-2008 had smaller sleeve restriction. Group 2 patients operated in 2009-2012 had major sleeve restriction. All procedures were performed without over-sewing of the staple line. The average %EBMIL (excess body mass index loss) in group 1 patients with minor sleeve restriction reached 54.1% and average %EWL (excess weight loss) was 50.8% while in group 2 with major sleeve restriction the average %EBMIL reached 69.7% and average %EWL was 66.8%. Final weight reduction was significantly higher in group 2 patients compared to group 1 patients with smaller sleeve restriction. Out of 49 patients with preoperatively diagnosed T2DM (type 2 diabetes mellitus) was completely resolved in 70.8%. Pre-operatively diagnosed hypertension normalized in 64.2%, improved in 23.2%, and remained unchanged in 12.6% of patients. Carefully performed LSG without over-sewing the staple line is feasible and safe. A better weight-reducing effect was present in patients with major sleeve restriction.

    The optimal technique for gastrointestinal anastomosis remains controversial in emergency laparotomy. The aim of this meta-analysis was to compare outcomes of stapled versus handsewn anastomosis after emergency bowel resection. A systematic review was performed for studies comparing outcomes after emergency laparotomy using stapled versus handsewn anastomosis until July 2014 (PROSPERO registry number: CRD42013006183). The primary endpoint was anastomotic failure, a composite measure of leak, abscess and fistula. Odds ratio (OR; with 95% CI) and weighted mean differences were calculated using meta-analytical techniques. Subgroup analysis was conducted for trauma surgery (TS) and emergency general surgery (EGS) cohorts. Risk of bias for each study was calculated using the Newcastle-Ottawa scale for cohort studies, and Cochrane Collaboration's tool for randomized trials. The final analysis included 7 studies of 1,120 patients, with a total of 1,205 anastomoses. There were 5 TS studies and 2 EGS studies. There were no differences in anastomotic failure between handsewn and stapled techniques on an individual anastomosis level (OR, 1.53; 95% CI, 0.97-2.43; P = .070), or on an individual patient level (OR, 1.44; 95% CI, 0.92-2.25; P = .110). There were no differences in the individual rates of anastomotic leak, abscess, fistulae, or postoperative deaths between techniques. Subgroup analysis of EGS and TS studies demonstrated no superior operative technique. Available evidence is sparse and at high risk of bias, and neither stapling nor handsewing is justifiably favored in emergency laparotomy. Surgeons might therefore select the technique of their own choice with caution owing to unresolved uncertainty. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Aims :A prospective clinical audit of all patients undergoing laparoscopic surgery with the intention of primary colonic left-sided intracorporeal stapled anastomosis to identify the rate of anastomotic leaks on an intention to treat basis with or without defunctioning stoma. Materials and Methods : All patients undergoing laparoscopic colorectal surgery resulting in left-sided stapled anastomosis were included with no selection criteria applied. All operations were conducted by the same surgical team and the same preparation and intraoperative methods were used. The factors analyzed for this audit were patient demographics (age and sex, indication for operation, procedure performed, height of anastomosis, leak rate and the outcome, inpatient stay, mortality, rate of defunctioning stomas, and rate of conversion to open procedure. Results for anastomotic leakage were compared with known results from the Wessex Colorectal Audit for open colorectal surgery. Results : A total of 69 patients (43 females, 26 males; median age 69 years, range 19 - 86 years underwent colonic procedures with left-sided intracorporeal stapled anastomoses. Of these, 14 patients underwent reversal of Hartmann′s, 42 - Anterior Resection, 11 - Sigmoid Colectomy, 2 - Left Hemicolectomy. Excluding reversals of Hartmann′s, 29 operations were performed for malignant and 26 for benign disease. Five patients were defunctioned, and 3 were subsequently reversed. The median height of anastomosis was 12 cm, range 4 - 18 cm from anal verge as measured either intra-operatively, or by rigid sigmoidoscopy post-operatively. Four cases were converted to open surgery. There was 1 post-operative death within 30 days. There was 1 anastomotic leak (the patient that died, and 1 patient developed a colo-vesical fistula. Median post-operative stay was 7 days, range 2-19. Conclusion : This clinical audit confirms that the anastomotic leak rate for left-sided colorectal stapled anastomosis is no

    Biofortification of staple crops has been proposed as a strategy to address micronutrient malnutrition, particularly with respect to insufficient intake of vitamin A, iron, zinc, and folate. The World Health Organization, in collaboration with the Food and Agriculture Organization of the United Nations and the Sackler Institute for Nutrition Science at the New York Academy of Sciences, convened a technical consultation entitled "Staple Crops Biofortified with Vitamins and Minerals: Considerations for a Public Health Strategy" in April 2016. Participants of the consultation reviewed the definition of biofortification of staple crops, patterns of crops production, processing, consumption, seed varieties, and micronutrient stability and bioavailability, as well as farmers' adoption and acceptability of the modified crops. Also discussed were economic, environmental, safety, and equity aspects of biofortified crops, as well as legal, policy, regulatory, and ethical issues for the implementation of biofortification strategies in agriculture and nutrition. Consultation working groups identified important and emerging technical issues, lessons learned, and research priorities to better support the evidence of improved nutrition and unintended adverse effects of biofortification. This paper provides the background and rationale of the technical consultation, synopsizes the presentations, and provides a summary of the main considerations proposed by the working groups. © 2016 The Authors.

    The Akin proximal phalangeal osteotomy is commonly used in conjunction with metatarsal osteotomies to treat hallux valgus. Multiple fixation methods including suture, wire, screw, and staple fixation have been described. The aims of this study were to assess the intraoperative and postoperative complications and to evaluate short-term postoperative outcomes in patients who underwent Akin osteotomy with staple fixation. Forty-four patients (51 feet) with painful hallux valgus were retrospectively reviewed at an average of 40.4 ± 15.8 (range, 25.9 to 79.9) weeks following an Akin osteotomy with staple fixation. Patient reported preoperative and postoperative Visual Analog Score (VAS) (0 to 10, 0 = no pain) was recorded. Level of activity was reported postoperatively. Hallux valgus angles (HVAs), intermetatarsal angles (IMAs), and hallux valgus interphalangeus angles (IPAs) were evaluated on preoperative as well as final postoperative radiographs. Postoperative clinical and radiographic examinations were used to evaluate for complications. Mean VAS improved from 4.4 ± 2.6 to 1.0 ± 1.2 (P hallux valgus correction with improvement in pain and hallux valgus deformity with a low risk for complications.

    Analysis of food security level of household is a novelty of measurement standards which usually includes regional and national levels. With household approach is expected to provide the basis of sharp food policy formulation. The purpose of this study are to identify the condition of self-sufficiency in staple foods, and to find the main factors affecting the dynamics of self-sufficiency in staple foods on farm household level in Great Solo. Using primary data from 50 farmers in the sample and secondary data in Great Solo (Surakarta city, Boyolali, Sukoharjo, Karanganyar, Wonogiri, Sragen and Klaten). Compiled panel data were analyzed with linear probability regression models to produce a good model. The results showed that farm households in Great Solo has a surplus of staple food (rice) with an average consumption rate of 96.8 kg/capita/year. This number is lower than the national rate of 136.7 kg/capita/year. The main factors affecting the level of food self-sufficiency in the farmer household level are: rice production, rice consumption, land tenure, and number of family members. Key recommendations from this study are; improvement scale of the land cultivation for rice farming and non-rice diversification consumption.

    Although SILS has become an increasingly popular type of surgery, its application for gastric submucosal tumors (SMT) has been only sporadically reported. We herein describe 12 recent cases with gastric SMT located in the greater curvature or anterior wall. The aim is to validate technical feasibility and safety of single-incision laparoscopic partial gastrectomy. Thus far, this is one of the largest series of patients with gastric SMT who underwent SILS. From July 2009 to April 2013, single-incision laparoscopic partial gastrectomy was attempted in 12 consecutive patients with gastric SMT. Three trocars were assembled in the umbilical incision, and the lesion was mobilized and staple-resected with endoscopic stapling devices. SILS surgery was successfully completed without any additional trocars. The median operating time was 96.5 min, and median blood loss was 7.5 mL. The median tumor size was 30 mm, with histopathologic diagnosis of gastrointestinal stromal tumor (10) and schwannoma (2). There was no immediate postoperative morbidity. During a median follow-up of 12 months, all patients were on full regular diet without any gastrointestinal symptoms. SILS with transumbilical gastric stapling is a safe and practical alternative to conventional multiport laparoscopy in patients with gastric SMT, except for cases originating in the lesser curvature and close to the cardia/ pylorus. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    To compare the results of staple versus locking compression plate fixation after closing wedge high tibial osteotomy. A group of 23 patients (24 knees) who underwent box high tibial osteotomy and staple fixation was compared with another group of 19 patients (22 knees) who underwent a similar procedure but with locking compression plate fixation. Both groups were followed up for 3 years. The range of movement, Hospital for Special Surgery (HSS) Knee Score, time to full weight bearing, incidence of delayed union, femorotibial angle, and stage of osteoarthritis were compared. At 6 months after the operation, the median HSS score and the proportion of patients with excellent or good scores were significantly higher in the locking compression plate than the staple fixation group (76 vs 62, p=0.003; 75% vs 42%, p=0.0354), but not at one and 3 years. The range of movement was significantly greater in the locking compression plate fixation group in the short term (6 weeks, 3 and 6 months), but not after one year. The median time to full weight bearing was significantly shorter in the locking compression plate fixation group (86 vs 116 days, perror, in the femorotibial angle or correction loss between the 2 groups. Locking compression plate fixation obviates the use of plaster casts, enables early mobilisation and bone union, and reduces the numbers with delayed union and the time to full weight bearing. Longer-term studies are needed to evaluate its effect on revarisation and arthropathy.

    Full Text Available This article reports the results of investigations carried out to produce yarns consisting of staple carbon fiber (CF obtained from process waste for the manufacturing of composites suitable especially for thermoset applications. For this purpose, a comparative analysis is done on processability between 100% staple CF and 60 weight% staple CF mixed with 40 weight% PVA fibers in carding, drawing and spinning process. The hybrid yarns are produced by varying twist level. The PVA fibers of the hybrid yarn are then dissolved using hot water treatment. The mechanical properties of yarns consisting of 100% staple CF and hybrid yarns consisting of staple CF and PVA before and after hot water treatment are investigated. Furthermore, test specimen is also prepared by impregnating 100% staple CF yarn and the hybrid yarns (after the dissolving of PVA with epoxy resin. The results of the tensile test of the yarns in consolidated state reveals that the hybrid yarn produced with 80 T/m after hot water treatment exhibits approximately 75% of the tensile strength of virgin filament tow, and it is expected that the hybrid yarns can be applied for the manufacturing of thermoset based composites for load bearing structures.

    Laparoscopic sleeve gastrectomy (LSG) has been recognized as a primary procedure for the surgical management of morbid obesity. Staple-line leaks and hemorrhage are two associated complications. Staple-line buttressing materials have been suggested to decrease these complications. When used during LSG, few published papers exist that compare the incidence of leak or hemorrhage to that of nonreinforced staple-lines. The purpose of this study was to compare the incidence of leak and hemorrhage in patients who did and did not receive reinforcement with Seamguard (W.L. Gore & Associates, Flagstaff, AZ). This is a retrospective analysis of patients undergoing LSG. All patients met National Institutes of Health criteria and each had an extensive preoperative evaluation. Data was collected from inpatient and outpatient medical records. Fifty-nine patients received reinforcement and 80 patients did not. There was no significant difference in mean body mass index, age, or gender make-up between the two groups. The overall incidence of leak was 3.60 per cent. The incidence was 3.39 per cent in patients who received reinforcement and 3.75 per cent in those who did not. This was not statistically significant. There was no incidence of staple-line hemorrhage in either group. There is no conclusive evidence that Seamguard reduces staple-line leakage or hemorrhage. Studies involving a larger number of patients are necessary before recommending staple-line reinforcement.

    To develop a technique for approximation of end-to-end intestinal anastomoses by using a disposable skin stapler and to compare the stapling technique with an interrupted hand-sewn approximating end-to-end anastomosis of the canine jejunum. In vitro evaluation of the stapling technique, followed by an in vivo study of healing and clinical response in dogs. 18 mixed-breed adult dogs. The anastomotic technique was developed and tested in fresh canine jejunum. Fourteen stapled approximating anastomoses (SAA) and 14 hand-sewn approximating anastomoses (HAA) were performed in 6 cadavers under simulated surgical conditions. Anastomotic construction times, initial bursting strengths, initial lumen diameters, and gross appearance of the 2 techniques were compared. Healing and clinical response were evaluated in 12 purpose-bred dogs assigned to 2 groups of 6 animals each. Each dog had 1 SAA and 1 HAA performed in the jejunum, 50 cm apart. Six dogs were killed on postoperative day 4, and 6 dogs were killed on postoperative day 21. Anastomotic construction time, gross and histological healing, bursting strength, lumen diameter, and circumference were compared between techniques. Mean construction time for SAA was significantly faster than for HAA (P = .0001). None of the anastomoses leaked, and there were no major clinical complications in any dog. Bursting strengths were not significantly different at any time for the 2 techniques. Initial bursting strength was 31% to 35% of the normal jejunum. A nonsignificant decrease in bursting strength was observed by postoperative day 4 (26% to 28% of normal), and a significant increase in bursting strength was observed by postoperative day 21 (100% to 109% of normal). Neither technique decreased the initial lumen diameter. However, both techniques resulted in a similar degree of luminal stenosis as the anastomoses healed. Anastomotic lumen diameter was significantly decreased from normal in both groups at day 4 (86% to 88% of normal

    Full Text Available Background: Cesarean delivery is the most common surgical procedure and this prevalence is on the rise. Given these trends, cesarean wound complications, such as disruption or infection, remain an important cause of post-cesarean morbidity. Methods: We conducted a single-center randomized controlled trial that included women with viable pregnancies (≥24 weeks undergoing cesarean delivery at Motahary University Hospital, Urmia, Iran from April to November 2014. All cesarean types were included: scheduled or unscheduled and primary or repeat cesareans. Women were excluded for the following reasons: inability to obtain informed consent, immune compromising disease (e.g. AIDS, chronic steroid use, diabetic mellitus and BMI≥30. Of 266 women, 133 were randomized to staples and 133 women to suture group. Results: The mean±SD age of the staples group was 27.6±5.4 years and mean±SD age of suture was 28.7±5.9 years. Multiparity is the most frequent in both groups that by using Chi-square test, no significant differences were observed between the two groups (P=0.393. The most frequent indication for cesarean section in both groups was history of cesarean section in staple 40 cases (30.1% and suture 32 cases (24.1%. The survey was conducted using the Chi-square test was not significant (P=0.381. Pain at 6 weeks postoperatively was significantly less in the staple group (P=0.001. Operative time was longer with suture closure (4.68±0.67 versus 1.03±0.07 minute, P<0.001. The Vancouver scale score was significantly less in suture closure (6.6±0.8 versus 7.5±0.9, P=0.001. Wound disruption was significantly less in suture closure (3.8% versus 11.3%, P=0.017. Conclusion: The staple group had low pain and operation time but had a significant wound disruption and scar. The patients who have suffered a significant wound disruption were affected by age (P=0.022 and BMI (P=0.001 at compared those who were not affected by factors such as age or high BMI as

    Purpose: To develop a fully-automatic longitudinal bone and marrow segmentation method in the pelvic region from dual energy computed tomography (DECT). Methods: We developed a two-step automatic bone and marrow segmentation method for simultaneous longitudinal evaluation of patients with metastatic bone disease using dual energy CT (DECT). Our approach transforms the DECT images into a multi-material decomposition (MMD) model that represents the voxels as a mixture of multiple materials. A support vector machine (SVM) was trained using a single scan. In the first step of the longitudinal segmentation the trained SVM model detects bone and marrow structures on all available longitudinal scans. Segmentation is further refined through active contour segmentation. In the second step, the segmentations from the individual scans are merged by employing the simultaneous truth and performance level estimation (STAPLE) algorithm. The scans are registered using affine and deformable registration. We found that our approach improves the segmentation in all the scans under reliable registration performance between the same scans. Improving registration was not under the scope of this work. Results: We applied our approach to segment bone and marrow in DECT scans in the pelvic regions for multiple patients. Each patient had three to five follow up scans. All the patients in the analysis had artificial metal prostheses which introduced challenges for the registration. Our algorithm achieved reasonable accurate segmentation despite the presence of metal artifacts and high-density oral contrast in neighboring structures. Our approach obtained an overall segmentation accuracy of 80% using DICE metric. Conclusion: We developed a two-step automatic longitudinal segmentation technique for bone and marrow region structures in the pelvic areas from dual energy CT. Our approach achieves robust segmentation despite the presence of confounding structures with similar intensities as the

    For most brews, alcohol fermentation and lactic fermentation take place simultaneously during the brewing process, and alcohol fermentation can progress smoothly because the propagation of various microorganisms is prevented by lactic fermentation. It is not necessary to cause lactic fermentation with a thing generated naturally and intentionally. The people living in the Dirashe area in southern Ethiopia drink three types of alcoholic beverages that are prepared from cereals. From these alcoholic beverages, parshot is prepared by the addition of plant leaves for lactic fermentation and nech chaka by adding cereal powder for lactic fermentation before alcohol fermentation. People living in the Dirashe area partake of parshot as part of their staple diet. The brewing process used for parshot and a food culture with alcoholic beverages as parts of the staple diet are rare worldwide. This article discusses the significance of using lactic fermentation before alcoholic fermentation and focuses on lactic fermentation in the brewing methods used for the three kinds of alcoholic beverages consumed in the Dirashe area. We initially observed the brewing process and obtained information about the process from the people in that area. Next, we determined the pH and analyzed the lactic acid (g/100 g) and ethanol (g/100 g) content during lactic fermentation of parshot and nech chaka; the ethyl acetate (mg/100 g) and volatile base nitrogen (mg/100 g) content during this period was also analyzed. In addition, we compared the ethanol (g/100 g) content of all three kinds of alcoholic beverages after completion of brewing. The results showed that it was possible to consume large quantities of these alcoholic beverages because of the use of lactic fermentation before alcoholic fermentation, which improved the safety and preservation characteristics of the beverages by preventing the propagation of various microorganisms, improving flavor, and controlling the alcohol level.

    Aims: To assess accuracy of multidetector computed tomography (MDCT) and individual radiological signs in the diagnosis of anastomotic leaks. Materials and methods: Patients undergoing anterior resection with a stapled anastomosis over a 2 year period were identified. Electronic and clinical records of these patients were reviewed. Unenhanced and/or enhanced MDCT was performed with intravenous and/or per-rectal contrast medium and read by a radiologist blinded to the patients' clinical details to determine the sensitivity and specificity of specific findings at MDCT for identifying leaks. Results: Seventeen percent (30/170) of the anterior resections were suspected to have an anastomotic leak. Ninety-three percent (28/30) of patients underwent MDCT. Seven point six percent (11+2/170) had a confirmed leak. Two patients underwent surgery without MDCT. A leak was confirmed by MDCT in 91% (10/11) of patients. The sensitivity, specificity, and positive and negative predictive values of MDCT in diagnosing a leak was 0.91, 1, 1, and 0.95, respectively. The sensitivity of peri-anastomotic air, peri-anastomotic collection, extravasation of rectal contrast medium, and staple line integrity was 0.81, 0.63, 0.54, and 0.72, respectively. Use of rectal contrast medium (8/11 cases) increased the subjective ease of diagnosis and was the only sign in one patient. Conclusions: Presence of peri-anastomotic air is a reliable marker of anastomotic leaks at MDCT. Leakage of rectal contrast medium is highly accurate and increases confidence of diagnosis. The appearance of the staple line itself is not accurate in assessing anastomotic integrity

    Childhood diet is important for brain development. Furthermore, the quality of breakfast is thought to affect the cognitive functioning of well-nourished children. To analyze the relationship among breakfast staple type, gray matter volume, and intelligence quotient (IQ) in 290 healthy children, we used magnetic resonance images and applied voxel-based morphometry. We divided subjects into rice, bread, and both groups according to their breakfast staple. We showed that the rice group had a significantly larger gray matter ratio (gray matter volume percentage divided by intracranial volume) and significantly larger regional gray matter volumes of several regions, including the left superior temporal gyrus. The bread group had significantly larger regional gray and white matter volumes of several regions, including the right frontoparietal region. The perceptual organization index (POI; IQ subcomponent) of the rice group was significantly higher than that of the bread group. All analyses were adjusted for age, gender, intracranial volume, socioeconomic status, average weekly frequency of having breakfast, and number of side dishes eaten for breakfast. Although several factors may have affected the results, one possible mechanism underlying the difference between the bread and the rice groups may be the difference in the glycemic index (GI) of these two substances; foods with a low GI are associated with less blood-glucose fluctuation than are those with a high GI. Our study suggests that breakfast staple type affects brain gray and white matter volumes and cognitive function in healthy children; therefore, a diet of optimal nutrition is important for brain maturation during childhood and adolescence.

    Warren, Patrick B.; Ball, Robin C.; Goldstein, Raymond E.

    2018-04-01

    The problem of how staple yarns transmit tension is addressed within abstract models in which the Amontons-Coulomb friction laws yield a linear programing (LP) problem for the tensions in the fiber elements. We find there is a percolation transition such that above the percolation threshold the transmitted tension is in principle unbounded. We determine that the mean slack in the LP constraints is a suitable order parameter to characterize this supercritical state. We argue the mechanism is generic, and in practical terms, it corresponds to a switch from a ductile to a brittle failure mode accompanied by a significant increase in mechanical strength.

    A low glycemic index (GI) diet is beneficial for glucose control in patients with diabetes mellitus. This study aimed to investigate the influence of a low-GI diet on postprandial glucose levels in women with gestational diabetes mellitus (GDM). Pregnant women with GDM were randomized to receive a normal diabetic control diet or a low-GI staple diet for 5 days. A low-GI staple food was used to replace rice in lunch and dinner for the low-GI staple diet group, whereas the total energy and carbohydrate levels remained equal in both groups. Fasting and postprandial glucose levels were determined daily. A total of 140 pregnant women with GDM were included in the study, including 66 in the low-GI staple diet group and 74 in the normal diabetic diet control group. No differences existed in baseline characteristics between the 2 groups (all P > 0.05). After dietary intervention, glucose levels were significantly reduced in the low-GI staple diet group (all P diet significantly reduces postprandial glucose levels in women with GDM.

    Full Text Available Bariatric surgery has become an integral part of morbid obesity treatment with well-defined indications. Some complications, specific or not, due to laparoscopic sleeve gastrectomy (LSG procedure have recently been described. We report a rare complication unpublished to date: a nasogastric section during great gastric curve stapling. A 44-year-old woman suffered of severe obesity (BMI 36.6 kg/m2 with failure of medical treatments for years. According to already published technique, a LSG was performed. Six hours postoperatively, a nurse removed the nasogastric tube according to the local protocol and the nasogastric tube was abnormally short, with staples at its extremity. Surgery was performed with peroperative endoscopy. In conclusion, this is the first publication of a nasogastric section during LSG. Therefore we report this case and propose a solution to prevent its occurrence. To avoid this kind of accident, we now systematically insert the nasogastric tube by mouth through a Guedel cannula. Then, to insert the calibrating bougie, we entirely withdraw the nasogastric tube.

    Levels of natural radioactivity in staple food products (maize and rice) from various localities of Tanzania have been studied. The average activity concentrations of {sup 40}K, {sup 232}Th and {sup 238}U in maize were 48.79 {+-} 0.11, 4.08 {+-} 0.01 and 13.23 {+-} 0.10 Bq kg{sup -1}, respectively. In rice the concentrations of {sup 40}K, {sup 232}Th and {sup 238}U were 24.67 {+-} 0.03, 3.82 {+-} 0.02 and 5.02 {+-} 0.02 Bq kg{sup -1}, respectively. {sup 137}Cs was detected in only one sample collected in Zanzibar. The sample, with activity concentration of 5.57 {+-} 0.01 Bq kg{sup -1}, had been imported from Thailand. The relatively high average concentrations of the radionuclides in maize compared to rice may be attributed to the extensive use of phosphate fertilizers in maize production in Tanzania. Total annual committed effective doses due to total {sup 232}Th and {sup 238}U intakes as a result of consumption of staple foodstuffs for infants, children and adults were 0.16, 0.29 and 0.36 mSv y{sup -1}, respectively, which are lower than the annual dose guideline for the general public.

    Although calorie dense, the starchy, tuberous roots of cassava provide the lowest sources of dietary protein within the major staple food crops (Manihot esculenta Crantz). (Montagnac JA, Davis CR, Tanumihardjo SA. (2009) Compr Rev Food Sci Food Saf 8:181–194). Cassava was genetically modified to express zeolin, a nutritionally balanced storage protein under control of the patatin promoter. Transgenic plants accumulated zeolin within de novo protein bodies localized within the root storage tissues, resulting in total protein levels of 12.5% dry weight within this tissue, a fourfold increase compared to non-transgenic controls. No significant differences were seen for morphological or agronomic characteristics of transgenic and wild type plants in the greenhouse and field trials, but relative to controls, levels of cyanogenic compounds were reduced by up to 55% in both leaf and root tissues of transgenic plants. Data described here represent a proof of concept towards the potential transformation of cassava from a starchy staple, devoid of storage protein, to one capable of supplying inexpensive, plant-based proteins for food, feed and industrial applications.

  14. A continuous STAPLE for scalar, vector, and tensor images: an application to DTI analysis.

    2009-06-01

    The comparison of images of a patient to a reference standard may enable the identification of structural brain changes. These comparisons may involve the use of vector or tensor images (i.e., 3-D images for which each voxel can be represented as an RN vector) such as diffusion tensor images (DTI) or transformations. The recent introduction of the Log-Euclidean framework for diffeomorphisms and tensors has greatly simplified the use of these images by allowing all the computations to be performed on a vector-space. However, many sources can result in a bias in the images, including disease or imaging artifacts. In order to estimate and compensate for these sources of variability, we developed a new algorithm, called continuous STAPLE, that estimates the reference standard underlying a set of vector images. This method, based on an expectation-maximization method similar in principle to the validation method STAPLE, also estimates for each image a set of parameters characterizing their bias and variance with respect to the reference standard. We demonstrate how to use these parameters for the detection of atypical images or outliers in the population under study. We identified significant differences between the tensors of diffusion images of multiple sclerosis patients and those of control subjects in the vicinity of lesions.

  15. Isoform-Selective Disruption of AKAP-Localized PKA Using Hydrocarbon Stapled Peptides

    Science.gov (United States)

    2015-01-01

    A-kinase anchoring proteins (AKAPs) play an important role in the spatial and temporal regulation of protein kinase A (PKA) by scaffolding critical intracellular signaling complexes. Here we report the design of conformationally constrained peptides that disrupt interactions between PKA and AKAPs in an isoform-selective manner. Peptides derived from the A Kinase Binding (AKB) domain of several AKAPs were chemically modified to contain an all-hydrocarbon staple and target the docking/dimerization domain of PKA-R, thereby occluding AKAP interactions. The peptides are cell-permeable against diverse human cell lines, are highly isoform-selective for PKA-RII, and can effectively inhibit interactions between AKAPs and PKA-RII in intact cells. These peptides can be applied as useful reagents in cell-based studies to selectively disrupt AKAP-localized PKA-RII activity and block AKAP signaling complexes. In summary, the novel hydrocarbon-stapled peptides developed in this study represent a new class of AKAP disruptors to study compartmentalized RII-regulated PKA signaling in cells. PMID:24422448

    This study evaluated the early results (with particular reference to complications) of stapled transanal rectal resection (STARR) carried out using the CCS-30 Contour® Transtar™ device. The procedure was performed in a single centre on patients with obstucted defecation caused by rectocele or rectal intussusception. From July 2007 to February 2009, 133 patients were treated. Preoperatively, all underwent clinical examination, transanal ultrasonography, anorectal manometry and cinedefaecography. Obstructed defaecation syndrome was assessed using the Cleveland Clinic Constipation Score (CCC-S). Early postoperative complications and those occurring within 6 months were recorded. The median follow-up period was 19 (range 12-30) months. The mean ± standard deviation preoperative CCC-S of 19.4 ± 7.1 decreased to 10.1 ± 9.0 postoperatively. The early complication rate was 15.7% and included rectovaginal fistula (n = 1), rectal perforation (n = 1), posterior dehiscence (n = 4), further surgery for retained staples (n = 2), postoperative bleeding (n = 2) and postoperative impaired continence (n = 11). STARR using the Contour Transtar device seems to be effective for treating obstructed defaecation. However, serious complications may occur. © 2011 The Authors.

    Full Text Available Abstract Background Surgical site wound closure plays a vital role in post-operative success. This effect is magnified in regard to commonly performed elective procedures such as total knee arthroplasty. The use of either sutures or staples for skin re-approximation remains a contested subject, which may have a significant impact on both patient safety and surgical outcome. The literature remains divided on this topic. Methods Two cohorts of patients at a level one trauma and regional referral center were reviewed. Cohorts consisted of consecutive total knee arthroplasties performed by two surgeons who achieved surgical wound re-approximation by either staples or absorbable subcuticular sutures. Outcome variables included time of surgery, wound dehiscence, surgical site infection per Center for Disease Control criteria and repeat procedures for debridement and re-closure. Results 181 patients qualified for study inclusion. Staples were employed in 82 cases (45.3% of total and sutures in 99 cases (54.7%. The staples group had no complications while the sutures group had 9 (9.1%. These consisted of: 4 infections (2 superficial, one deep, one organ/space; three patients required re-suturing for dehiscence; one allergic type reaction to suture material; and one gout flare resulting in dehiscence. The mean surgical time with sutures was 122.3 minutes (sd = 33.4 and with staples was 114 minutes (sd = 24.4. Conclusion This study demonstrated significantly fewer complications with staple use than with suture use. While all complications found in this study cannot be directly attributed to skin re-approximation method, the need for further prospective, randomized trials is established.

  19. Evaluating the synchronicity in yield variations of staple crops at global scale

    2014-12-01

    Reflecting the recent globalization trend in world commodity market, several major production countries are producing large amount of staple crops, especially, maize and soybean. Thus, simultaneous crop failure (abrupt reduction in crop yield, lean year) due to extreme weather and/or climate change could lead to unstable food supply. This study try to examine the synchronicity in yield variations of staple crops at global scale. We use a gridded crop yields database, which includes the historical year-to-year changes in staple crop yields with a spatial resolution of 1.125 degree in latitude/longitude during a period of 1982-2006 (Iizumi et al. 2013). It has been constructed based on the agriculture statistics issued by local administrative bureaus in each country. For the regions being lack of data, an interpolation was conducted to obtain the values referring to the NPP estimates from satellite data as well as FAO country yield. For each time series of the target crop yield, we firstly applied a local kernel regression to represent the long-term trend component. Next, the deviations of yearly yield from the long-term trend component were defined as ΔY(i, y) in year y at grid i. Then, the correlation of deviation between grids i and j in year y is defined as Cij(y) = ΔY(i, y) ΔY(j, y). In addition, Pij = represents the time-averaged correlation of deviation between grids i and j. Bracket means the time average operation over 25 years (1982-2006). As the results, figures show the time changes in the number of grid pairs, in which both the deviation are negative. It represent the time changes in ratio of the grid pairs where both crop yields synchronically decreased to the total grid pairs. The years denoted by arrows in the figures indicate the case that all the ratios of three country pairs (i.e. China-USA, USA-Brazil and Brazil-China) are relatively larger (>0.6 for soybean and >0.5 for maize). This suggests that the reductions in crop yield occurred

    Phoropters are the most common instrument used to detect refractive errors. During a refractive exam, lenses are flipped in front of the patient who looks at the eye chart and tries to read the symbols. The procedure is fully dependent on the cooperation of the patient to read the eye chart, provides only a subjective measurement of visual acuity, and can at best provide a rough estimate of the patient's vision. Phoropters are difficult to use for mass screenings requiring a skilled examiner, and it is hard to screen young children and the elderly etc. We have developed a simplified, lightweight automatic phoropter that can measure the optical error of the eye objectively without requiring the patient's input. The automatic holographic adaptive phoropter is based on a Shack-Hartmann wave front sensor and three computercontrolled fluidic lenses. The fluidic lens system is designed to be able to provide power and astigmatic corrections over a large range of corrections without the need for verbal feedback from the patient in less than 20 seconds.

    Full Text Available Objective: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires inter- vention. There is limited published data on its management. Design: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postop- erative bleeding. Results: Ileoscopy demonstrated a large, long blood clot in the lumen of efferent limb, but no sign of active bleeding was identified. Pouchoscopy showed that lumen of pouch body as well as afferent limb was filled with maroon-colored liquid stool. Pouch and neo-terminal ileum mucosa was normal. Two dislodged staples at the anastomotic line with sharp tips towards the lumen were found, with activating bleeding at one site. The staples were re- moved by biopsy forceps, and active bleeding was successfully controlled by the deploy- ment of one endoclip. Conclusions: We reported the first case that postoperative pouch bleeding, which was caused by dislodged staples, was successfully managed by endoscopic removal of the staples com- bined with clipping. Resumo: Objetivo: O sangramento pós-operatório da bolsa ileal é uma complicação rara, mas prejudi- cial após abordagem cirúrgica da bolsa ileal. Esse sangramento é geralmente autolimitado, porém, requer intervenção quando contínuo. Não há dados publicados sobre o tratamento. Método: Ileoscopia através de estoma para ileostomia em alça e endoscopia via ânus para a bolsa ileal foram realizadas sob sedação para diagnóstico e tratamento do sangramento pós-operatório. Resultados: A ileoscopia demonstrou um grande e longo coágulo sanguíneo no lúmen do ramo eferente, mas nenhum sinal de sangramento ativo foi identificado. A endoscopia da bolsa ileal mostrou que os lumens do corpo da bolsa e ramo aferente estavam cheios de fe- zes líquidas de cor marrom. A

    Surgical technique and perioperative management in rectal cancer surgery have been substantially improved and standardized during the last decades. However, anastomotic leakage following low anterior resection still is a significant problem. Based on animal experimental data of improved healing of compression anastomosis, we hypothesized that a compression anastomotic device might improve healing rates of the highest-risk anastomoses. All low anterior resections for rectal cancer performed or directly supervised by the senior author between January 2004 and June 2012 were analyzed. Only patients with a stapled or compression anastomosis located within 6 cm from the anal verge were included. Until December 2008, circular staplers were employed, while since January 2009, a novel compression anastomotic device was used for rectal reconstruction exclusively. Out of 197 patients operated for rectal cancer, a total of 96 (34 females, 35.4 %) fulfilled inclusion criteria. Fifty-eight (60.4 %) were reconstructed with circular staplers and 38 (39.6 %) using a compression anastomotic device. Significantly, more laparoscopic procedures were recorded in the compression anastomosis group, but distribution of gender, age, body mass index, American Society of Anaesthesiologists score, rate of preoperative radiotherapy, tumor staging, or stoma diversion rate were similar. Anastomotic leakage was observed in seven cases (7/58, 12.1 %) in the stapled and twice (2/38, 5.3 %) in the compression anastomosis group (p = 0.26). In this series, rectal reconstruction following low anterior resection using a novel compression anastomotic device was safe and (at least) equally effective compared to traditional circular staplers concerning leak rate.

    Research on perennial staple crops has increased in the past ten years due to their potential to improve ecosystem services in agricultural systems. However, multiple past breeding efforts as well as research on traditional ratoon systems mean there is already a broad body of literature on perennial crops. In this review, we compare the development of research on perennial staple crops, including wheat, rice, rye, sorghum, and pigeon pea. We utilized the advanced search capabilities of Web of Science, Scopus, ScienceDirect, and Agricola to gather a library of 914 articles published from 1930 to the present. We analyzed the metadata in the entire library and in collections of literature on each crop to understand trends in research and publishing. In addition, we applied topic modeling to the article abstracts, a type of text analysis that identifies frequently co-occurring terms and latent topics. We found: 1.) Research on perennials is increasing overall, but individual crops have each seen periods of heightened interest and research activity; 2.) Specialist journals play an important role in supporting early research efforts. Research often begins within communities of specialists or breeders for the individual crop before transitioning to a more general scientific audience; 3.) Existing perennial agricultural systems and their domesticated crop material, such as ratoon rice systems, can provide a useful foundation for breeding efforts, accelerating the development of truly perennial crops and farming systems; 4.) Primary research is lacking for crops that are produced on a smaller scale globally, such as pigeon pea and sorghum, and on the ecosystem service benefits of perennial agricultural systems.

    Ileal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. All UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. A total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). In this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA. Copyright © 2016 Elsevier Inc. All rights reserved.

    Bcl-2 family proteins regulate apoptosis, and aberrant interactions of overexpressed antiapoptotic family members such as Mcl-1 promote cell transformation, cancer survival, and resistance to chemotherapy. Discovering potent and selective Mcl-1 inhibitors that can relieve apoptotic blockades is thus a high priority for cancer research. An attractive strategy for disabling Mcl-1 involves using designer peptides to competitively engage its binding groove, mimicking the structural mechanism of action of native sensitizer BH3-only proteins. We transformed Mcl-1-binding peptides into α-helical, cell-penetrating constructs that are selectively cytotoxic to Mcl-1-dependent cancer cells. Critical to the design of effective inhibitors was our introduction of an all-hydrocarbon cross-link or "staple" that stabilizes α-helical structure, increases target binding affinity, and independently confers binding specificity for Mcl-1 over related Bcl-2 family paralogs. Two crystal structures of complexes at 1.4 Å and 1.9 Å resolution demonstrate how the hydrophobic staple induces an unanticipated structural rearrangement in Mcl-1 upon binding. Systematic sampling of staple location and iterative optimization of peptide sequence in accordance with established design principles provided peptides that target intracellular Mcl-1. This work provides proof of concept for the development of potent, selective, and cell-permeable stapled peptides for therapeutic targeting of Mcl-1 in cancer, applying a design and validation workflow applicable to a host of challenging biomedical targets.

    Intoduction and aim: The aim of the study was to compare the resistance to pressure of stapled and manually handsewn intestinal suture lines on in vitro pig intestine model. We performed different types of stapled and manual sutures and the pressure level was measured using a differential pressure manometer. Although the hand-sewn end-to-end suture turned out to be the most resistant to pressure, statistical analysis revealed no significant differences compared to stapled suture (p = 0.49). In stump closure techniques, we observed a statistically high significance in resistance to pressure in the favour of manual stump closure (p = 0.004).Regarding side-to-side sutures we did not find any statistically significant differences in resistance to pressure between the techniques (p = 0.06). We can conclude that regarding the stump closure, the most resistant to pressure is the hand-sewn procedure, but in the other types of anastomosis, no significant differences was found between the stapled and hand-sewn techniques.

    At present, none of the conventional surgical treatments of solitary rectal ulcer associated with internal rectal prolapse seems to be satisfactory because of the high incidence of recurrence. The stapled transanal rectal resection has been demonstrated to successfully cure patients with internal rectal prolapse associated with rectocele, or prolapsed hemorrhoids. This prospective study was designed to evaluate the short-term and long-term results of stapled transanal rectal resection in patients affected by solitary rectal ulcer associated with internal rectal prolapse and nonresponders to biofeedback therapy. Fourteen patients were selected on the basis of validated constipation and continence scorings, clinical examination, anorectal manometry, defecography, and colonoscopy and were submitted to biofeedback therapy. Ten nonresponders were operated on and followed up with incidence of failure, defined as no improvement of symptoms and/or recurrence of rectal ulceration, as the primary outcome measure. Operative time, hospital stay, postoperative pain, time to return to normal activity, overall patient satisfaction index, and presence of residual rectal prolapse also were evaluated. At a mean follow-up of 27.2 (range, 24-34) months, symptoms significantly improved, with 80 percent of excellent/good results and none of the ten operated patients showed a recurrence of rectal ulcer. Operative time, hospital stay, and time to return to normal activity were similar to those reported after stapled transanal rectal resection for obstructed defecation, whereas postoperative pain was slightly higher. One patient complained of perineal abscess, requiring surgery. The stapled transanal rectal resection is safe and effective in the cure of solitary rectal ulcer associated with internal rectal prolapse, with minimal complications and no recurrences after two years. Randomized trials with sufficient number of patients are necessary to compare the efficacy of stapled transanal

    Full Text Available Introduction: Laparoscopic sleeve gastrectomy (LSG is one of the most efficient bariatric interventions in morbidly obese patients. The most severe risk of this procedure seems to be the staple line leak, and the management of this complication can be very arduous. Aim : To share our experience in managing the staple line leak after LSG and to help to find the best procedure that should be preferred. Material and methods : In the 2010–2015 period we performed 223 LSG, with about 5 demonstrating severe complications – two patients with severe bleeding requiring revision surgery, and three patients with resection surface leak. Results : We always primarily treated the staple line leak with a laparoscopic revision. Once the fistula did not spontaneously close after this treatment. A series of other methods were then indicated for this patient and only the sixth one resulted in the desirable therapeutic success. At first, our team opted for laparoscopic revision with drainage. The next procedure involved applying Ovesco and Boston clips. As a third method we performed abscess drainage through a nasobiliary tube inserted via gastroscopy. Due to failure we performed the second laparoscopic revision with staple line resuture, the next intervention was an open revision with fistula excision and suture, and finally we opted for the application of a self-expanding metallic stent, which proved to be definitely curative. Conclusions : Without any guidelines it is very difficult to determine the right procedure addressing the staple line leak after LSG. It depends mainly on the clinician’s experience and is lengthy and often untraditional.

    The Advanced Nuclear Technology Group of the Los Alamos National Laboratory is now using intelligent data-acquisition and analysis instrumentation for determining the multiplication of nuclear material. Earlier instrumentation, such as the large NIM-crate systems, depended on house power and required additional computation to determine multiplication or to estimate error. The portable, battery-powered multiplication measurement unit, with advanced computational power, acquires data, calculates multiplication, and completes error analysis automatically. Thus, the multiplication is determined easily and an available error estimate enables the user to judge the significance of results

    Obesity is a risk factor for infectious morbidity and wound complications after cesarean delivery. There are currently insufficient data to determine optimal skin closure technique for cesarean delivery, specifically for those women with class III obesity, defined as a body mass index ≥40 kg/m 2 . We sought to compare stainless steel staples vs subcuticular suture for skin closure for cesarean delivery in class III obese women with body mass index ≥40 kg/m 2 . We conducted a randomized controlled trial at 2 teaching hospitals from 2015 through 2016 in which women with body mass index ≥40 kg/m 2 undergoing cesarean delivery were randomly assigned to stainless steel staples or subcuticular suture skin closure. The primary outcome was composite wound complication defined as superficial or deep separation and infection occurring up to 6 weeks following delivery. Secondary outcomes included operative time, and patient pain and satisfaction scores. A total of 242 women were enrolled. In all, 119 in the staples group and 119 in the subcuticular suture group were analyzed. Maternal demographics and characteristics were similar in both groups. The composite wound complication frequency was 19.3% in the staples group and 17.6% in the subcuticular suture group (P = .74) with an overall wound complication incidence of 18.5% in the entire study cohort. There were also no differences in the frequencies of infection, or in superficial or deep wound separation between the 2 study groups. In a univariate analysis of predictors of wound complications, only current tobacco use was a significant predictor of wound complications (relative risk, 4.97; 95% confidence interval, 1.37-18.03; P = .02). Fewer women with staple closure would choose the same method with a future delivery (P = .01), however, self-reported pain and concern about wound healing were equal between the 2 groups. In class III obese women undergoing cesarean delivery, there was no difference in composite wound

    At this year's particle physics conference at Brighton, a parallel session was given over to instrumentation and detector development. While this work is vital to the health of research and its continued progress, its share of prime international conference time is limited. Instrumentation can be innovative three times — first when a new idea is outlined, secondly when it is shown to be feasible, and finally when it becomes productive in a real experiment, amassing useful data rather than operational experience. Hyams' examples showed that it can take a long time for a new idea to filter through these successive stages, if it ever makes it at all

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    Purpose. We report a comparison study of vertebral body stapling (VBS) versus a matched bracing cohort for immature patients with moderate (25 to 44°) idiopathic scoliosis (IS). Methods. 42 of 49 consecutive patients (86%) with IS were treated with VBS and followed for a minimum of 2 years. They were compared to 121 braced patients meeting identical inclusion criteria. 52 patients (66 curves) were matched according to age at start of treatment (10.6 years versus 11.1 years, resp. [P = 0.07]) and gender. Results. For thoracic curves 25–34°, VBS had a success rate (defined as curve progression <10°) of 81% versus 61% for bracing (P = 0.16). In thoracic curves 35–44°, VBS and bracing both had a poor success rate. For lumbar curves, success rates were similar in both groups for curves measuring 25–34°. Conclusion. In this comparison of two cohorts of patients with high-risk (Risser 0-1) moderate IS (25–44°), in smaller thoracic curves (25–34°) VBS provided better results as a clinical trend as compared to bracing. VBS was found not to be effective for thoracic curves ≥35°. For lumbar curves measuring 25–34°, results appear to be similar for both VBS and bracing, at 80% success. PMID:26618169

    This study presents basic data on the contents of Cr, Fe, Ni, Cu, Zn, As, Cd, Sb, Hg and Pb in staple foodstuffs and agriproducts grown in Russia (Astrakhansaia region and Belovo town) and Egypt (Helwan region). The dependence of the concentration of metals in agriproducts on the content and chemical form of existence in irrigation water and soils is indicated. The existence of high concentrations of heavy and toxic metals in food and agriproducts depends on the extent of soil contamination in the area, the quality of water used for irrigation purposes and the technology of growing and processing of a given product. The concentration of heavy and toxic metals in agriproducts directly depends on the chemical form of their existence in the soil, high concentrations of heavy metals if present as low mobility compounds in the soil, do not affect essentially their concentrations in plants. High content of some toxic metals (Cd, Hg, Pb) in livestock nutrition plants may prompt the conclusion that similar high concentration of the elements are in the livestock output such as red or white meat and eggs. It is hardly probable, however, that there is instant dependence between them. This problem needs further investigation. The irrigation of agricultural lands with sewage water of a plant, or even more, of a whole region must be done with great caution. The experience of the Helwan region shows this kind of irrigation results in a dramatic increase of the concentration of heavy and toxic metals in end products

    Full Text Available Introduction. Aim of the study was trying to draw a final flow chart for the management of gastric leaks after laparoscopic sleeve gastrectomy, based on the review of our cases over 10 years’ experience. Material and Methods. We retrospectively reviewed all patients who underwent LSG as a primary operation at the Bariatric Unit of Tor Vergata University Hospital in Rome from 2007 to 2015. Results. Patients included in the study were 418. There were 6 staple line leaks (1.44%. All patients with diagnosis of a leak were initially discharged home in good clinical conditions and then returned to A&E because of the complication. The mean interval between surgery and readmission for leak was 13,4 days (range 6–34 days, SD ± 11.85. We recorded one death (16.67% due to sepsis. The remaining five cases were successfully treated with a mean healing time of the gastric leak of 55,5 days (range 26–83 days; SD ± 25.44. Conclusion. Choosing the proper treatment depends on clinical stability and on the presence or not of collected abscess. Our treatment protocol showed being associated with low complication rate and minor discomfort to the patients, reducing the need for more invasive procedures.

    In order to decide an optimum countermeasure against farmland contaminations following a severe NPP accident, it is necessary to have a reliable tool for predicting the concentrations of radiocesium in crop plants. For the estimation of radionuclide concentrations in crop plants, various transfer parameters, which quantify the radionuclide transfer from one compartment to the next, are used in general. Some amount of transfer parameter data has been produced at the Korea Atomic Energy Research Institute (KAERI) over the last 30 years. The present work was conducted to collate the KAERI data on radiocesium in staple food crops and to suggest effective ways of using them for assessing the environmental impact of a nuclear accident. The transfer parameter values of radiocesium for rice, Chinese cabbage and radish varied considerably with soils and times of its deposition. The proposed representative values were mostly based on a limited amount of data so they cannot be considered to have a high representativeness. Accordingly, they are intended for provisional use and a continuous improvement should be made. It is necessary to produce a sufficient amount of additional domestic data on the indirect pathway by conducting root-uptake experiments with as many types of soil as possible

    We report our experience of concomitant laparoscopic treatment for enterocele and stapled transanal rectal resection (STARR) for rectocele and/or rectal prolapse in patients with complex obstructed defecation syndrome (ODS). From June 2005 to June 2007, we submitted 20 patients with ODS due to rectal prolapse and/or rectocele, combined with stable enterocele, to STARR and laparoscopic correction of the enterocele. Preoperative assessment included symptom evaluation with standardized questionnaires, clinical examination, colonoscopy, proctoscopy, anal sphincter ultrasonography, video-defecography with synchronous opacification of the ileal loops in all patients and colpography in female patients, and anorectal manometry. Follow-up was performed in the first, third, sixth, 12th, and 24th month after surgery. Eighteen (90%) patients were submitted to both procedures, simultaneously. One patient, previously submitted to STARR, underwent laparoscopic treatment of the enterocele. Postoperative complications occurred in two (10%) patients: one case of postoperative rectal bleeding and one case of retropneumoperitoneum. Median (range) preoperative and postoperative Altomare's obstructed defecation score was ten (6-14) and two (0-14), respectively (p<0.001). Median (range) preoperative and postoperative quality of life score was 79 (39-109) and 109 (50-126), respectively (p<0.001). No symptom related to ODS was detected at 6-month follow-up (19 patients) and at 24-month follow-up (19 patients). The combination of STARR and laparoscopy provides a safe and effective method to treat ODS caused by rectal internal prolapse and/or rectocele combined with enterocele.

    Proper mesh fixation is critical for successful TAPP laparoscopic hernia repair. Conventional mesh fixation may cause chronic neuralgia, groin paresthesia or other complications. This study aimed at introducing a new vacuum suction technique for mesh fixation and evaluating its efficacy and safety compared with traditional staple fixation way. Clinical data of 242 patients undergoing TAPP from July 2011 to March 2014 were retrospectively analyzed. Patients were divided into vacuum suction fixation group and staple fixation group. The operation time, hospital stay, complications, recurrence, visual analogue scale pain score and cost were evaluated. All surgeries were successful. The operation time of staple group was (42.34 ± 10.15) min for unilateral hernia and (64.08 ± 16.01) min for bilateral hernias. The postoperative hospital stay was (2.76 ± 0.84) days. One recurrence was observed (0.90%). For vacuum group, the operation time was (42.66 ± 7.76) min and (63.92 ± 10.49) min, and hospital stay was (2.60 ± 0.74) days. No recurrence was observed. There was no significant difference in recurrence, operation time, postoperative pain and hospital stay between two groups (P > 0.05). Average cost were (11,714 ± 726) RMB for vacuum group which was lower than staple group (14,837 ± 1568) RMB (P vacuum group, they were scrotal seroma (3.82%), temporary nerve paresthesia (3.05%), scrotal emphysema (1.53%) and uroschesis (1.53%). The incidence of scrotal emphysema was lower in vacuum group (P 0.05). Both techniques for mesh fixation are safe and effective. There is no significant difference in recurrence, operation time, postoperative pain or hospital stay. The vacuum suction fixation technique is more economical with lower incidence of scrotal emphysema.

    Full Text Available Introduction : Laparoscopic Roux-en-Y gastric bypass (LRYGB is a common, well-established procedure, but no consensus regarding selection of the gastrojejunostomy (GJ technique has been reached, and standardization of this precise technique is far from being achieved. Aim : To compare circular-stapled and linear-stapled GJ in LRYGB in terms of operative time and postoperative complications. Material and methods: This retrospective case-control study compared the perioperative and postoperative outcomes of LRYGB with a circular-stapled (LRYGB-CS versus linear-stapled (LRYGB-LS gastrojejunostomy. All patients, operated on in two academic referral care centers for bariatric surgery, were enrolled from April 2013 to June 2016. 457 patients were included (255 and 202 respectively in the LRYGB-CS and LRYGB-LS groups. After matching the groups for age, sex, body mass index, arterial hypertension, and presence of type 2 diabetes in a 1 : 1 ratio, 99 patients were enrolled in each. Results : The total operative time was longer in the LRYGB-LS group (140 vs. 85 min, p < 0.001. The postoperative hemorrhage and wound infection rates were lower in the LRYGB-LS group (2.1% vs. 10.3%, p = 0.021, and 1.0% vs. 9.3%, p = 0.011. The readmission rates were comparable (8.2% vs. 6.1%, p = 0.593. There was no significant difference in the incidence of gastrojejunostomy leakage, stricture, port-site hernia, or marginal ulcer. Conclusions : Both anastomosis types for LRYGB are safe and have low and comparable risks of postoperative complications. After LRYGB-CS, postoperative bleeding and wound infections are slightly more frequent; however, the operative time is shorter.

    To develop the pediatric Automatic Phonological Analysis Tools (APAT) and to estimate inter and intrajudge reliability, content validity, and concurrent validity. The APAT were constructed using Excel spreadsheets with formulas. The tools were presented to an expert panel for content validation. The corpus used in the Portuguese standardized test Teste Fonético-Fonológico - ALPE produced by 24 children with phonological delay or phonological disorder was recorded, transcribed, and then inserted into the APAT. Reliability and validity of APAT were analyzed. The APAT present strong inter- and intrajudge reliability (>97%). The content validity was also analyzed (ICC = 0.71), and concurrent validity revealed strong correlations between computerized and manual (traditional) methods. The development of these tools contributes to fill existing gaps in clinical practice and research, since previously there were no valid and reliable tools/instruments for automatic phonological analysis, which allowed the analysis of different corpora.

    To describe the use of disposable skin staples for intestinal resection and anastomosis in dogs and report associated dehiscence and mortality rates. Retrospective evaluation of medical records of dogs that underwent intestinal resection and anastomosis using disposable skin staples between 2000 and 2014. Data regarding patient signalment, indication for surgery, location of the resection and anastomosis, number of procedures performed, evidence of peritonitis at the time of surgery, surgeon qualifications, dehiscence, and mortality were obtained from the medical records. Mortality was defined as failure to survive beyond 10 days following resection and anastomosis. The overall mortality rate of patients undergoing intestinal resection and anastomosis was 12·7% (8/63). The most common indication for resection and anastomosis was neoplasia (20/63 [31·7%]), followed by foreign body removal (19/63 [30·2%]). The overall dehiscence rate was 4·8% (3/63). No difference in mortality associated with indication for surgery, whether multiple procedures were performed, surgeon qualifications, or evidence of peritonitis at the time of surgery was identified. In this retrospective study, the overall mortality and dehiscence rates using disposable skin staples were similar to previously reported outcomes following resection and anastomosis. © 2016 British Small Animal Veterinary Association.

    Anastomosis is one of the basic skills of a gastrointestinal surgeon. Stapling devices are widely used because stapled anastomosis (SA) can shorten operation times. Antiperistaltic stapled side-to-side anastomosis (SSSA) using linear staplers is a popular SA technique that is often referred to as "functional end-to-end anastomosis (FEEA)." The term "FEEA" has spread without any definite validation of its "function." The aim of this review is to show the heterogeneity of SA and conventional hand-sewn end-to-end anastomosis (HEEA) and to advocate the renaming of "FEEA." We conducted a narrative review of the literature on SSSA. We reviewed the literature on ileocolic and small intestinal anastomosis in colonic cancer, Crohn's disease and ileostomy closure due to the simplicity of the technique. The superiority of SSSA in comparison to HEEA has been demonstrated in previous clinical studies concerning gastrointestinal anastomosis. Additionally, experimental studies have shown the differences between the two anastomotic techniques on peristalsis and the intestinal bacteria at the anastomotic site. SSSA and HEEA affect the postoperative clinical outcome, electrophysiological peristalsis, and bacteriology in different manners; no current studies have shown the functional equality of SSSA and HEEA. However, the use of the terms "functional end-to-end anastomosis" and/or "FEEA" could cause confusion for surgeons and researchers and should therefore be avoided.

    For better understanding of the specification for seismic instrumentation of a nuclear power plant, the lecture gives some fundamental remarks to the seismic risk in the Federal Republic of Germany and to the data characterizing an earthquake event. Coming from the geophysical properties of an earthquake, the quantities are explained which are used in the design process of nuclear power plants. This process is shortly described in order to find the requirements for the specification of the seismic instrumentation. In addition the demands of licensing authorities are given. As an example the seismic instrumentation of KKP-1, BWR, is shown. The paper deals with kind and number of instruments, their location in the plant and their sensitivity and calibration. Final considerations deal with the evaluation of measured data and with plant operation after an earthquake. Some experience concerning the earthquake behaviour of equipment not designed to withstand earthquake loads is mentioned. This experience has initiated studies directed to quantification of the degree of conservatism of the assumptions in the seismic design of nuclear power plants. A final garget of these studies are more realistic design rules. (RW)

    Stained end-grafted DNA molecules about 20μm long are scraped away and stretched out by the spreading front of a bioadhesive vesicle. Tethered biotin ligands bind the vesicle bilayer to a streptavidin substrate, stapling the DNAs into frozen confinement paths. Image analysis of the stapled DNA gives access, within optical resolution, to the local stretching values of individual DNA molecules swept by the spreading front, and provides evidence of self-entanglements.

    Our book introduces a method to evaluate the accuracy of trend estimation algorithms under conditions similar to those encountered in real time series processing. This method is based on Monte Carlo experiments with artificial time series numerically generated by an original algorithm. The second part of the book contains several automatic algorithms for trend estimation and time series partitioning. The source codes of the computer programs implementing these original automatic algorithms are given in the appendix and will be freely available on the web. The book contains clear statement of the conditions and the approximations under which the algorithms work, as well as the proper interpretation of their results. We illustrate the functioning of the analyzed algorithms by processing time series from astrophysics, finance, biophysics, and paleoclimatology. The numerical experiment method extensively used in our book is already in common use in computational and statistical physics.

    Full Text Available Abstract Background The United Nations’ Millennium Development Goals Report, 2015, documents that, since 1990, the number of stunted children in sub-Saharan Africa has increased by 33% even though it has fallen in all other world regions. Recognizing this, in 2011 the Government of Uganda implemented a 5-year Nutrition Action Plan. One important tenet of the Plan is to lessen malnutrition in young children by discouraging over-consumption of nutritionally deficient, but plentiful, staple foods, which it defines as a type of food insecurity. Methods We use a sample of 6101 observations on 3427 children age five or less compiled from three annual waves of the Uganda National Panel Survey to measure undernourishment. We also use the World Health Organization’s Child Growth Standards to create a binary variable indicating stunting and another indicating wasting for each child in each year. We then use random effects to estimate binary logistic regressions that show that greater staple food concentrations affect the probability of stunting and wasting. Results The estimated coefficients are used to compute adjusted odds ratios (OR that estimate the effect of greater staple food concentration on the likelihood of stunting and the likelihood of wasting. Controlling for other relevant covariates, these odds ratios show that a greater proportion of staple foods in a child’s diet increases the likelihood of stunting (OR = 1.007, p = 0.005 as well as wasting (OR = 1.011, p = 0.034.

    Highly precise assay of plutonium metal is required for accountability measurements. We have developed an automatic titrator for this determination which eliminates analyst bias and requires much less analyst time. The analyst is only required to enter sample data and start the titration. The automated instrument titrates the sample, locates the end point, and outputs the results as a paper tape printout. Precision of the titration is less than 0.03% relative standard deviation for a single determination at the 250-mg plutonium level. The titration time is less than 5 min

    Full Text Available Web applications are becoming an essential part of our everyday lives. Many of our activities are dependent on the functionality and security of these applications. As the scale of these applications grows, injection vulnerabilities such as SQL injection are major security challenges for developers today. This paper presents the technique of automatic query sanitization to automatically remove SQL injection vulnerabilities in code. In our technique, a combination of static analysis and program transformation are used to automatically instrument web applications with sanitization code. We have implemented this technique in a tool named ASSIST (Automatic and Static SQL Injection Sanitization Tool for protecting Java-based web applications. Our experimental evaluation showed that our technique is effective against SQL injection vulnerabilities and has a low overhead.

    A portable Moessbauer spectrometer, developed for extraterrestrial applications, opens up new industrial applications of MBS. But for industrial applications, an available tool for fast data analysis is also required, and it should be easy to handle. The analysis of Moessbauer spectra and their parameters is a barrier for the popularity of this wide-applicable spectroscopic technique in industry. Based on experience, the analysis of a Moessbauer spectrum is time-consuming and requires the dedication of a specialist. However, the analysis of Moessbauer spectra, from the fitting to the identification of the sample phases, can be faster using by genetic algorithms, fuzzy logic and artificial neural networks. Industrial applications are very specific ones and the data analysis can be performed using these algorithms. In combination with an automatic analysis, the Moessbauer spectrometer can be used as a probe instrument which covers the main industrial needs for an on-line monitoring of its products, processes and case studies. Some of these real industrial applications will be discussed.

    Climate change continually affects our capabilities to feed the increasing population. Rising temperatures have the potential to shorten the crop growth duration and therefore reduce crop yields. In the past decades, China has successfully improved crop cultivars to stabilize, and even lengthen, the crop growth duration to make use of increasing heat resources. However, because of the complex cropping systems in the different regions of China, the possibility and the effectiveness of regulating crop growth duration to reduce the negative impacts of future climate change remain questionable. Here, we performed a projective analysis of the staple food crop productivity in double-rice, wheat-rice, wheat-maize, single-rice, and single-maize cropping systems in China using modeling approaches. The results indicated that from the present to the 2040s, the warming climate would shorten the growth duration of the current rice, wheat, and maize cultivars by 2-24, 11-13, and 9-29 days, respectively. The most significant shortening of the crop growth duration would be in Northeast China, where single-rice and single-maize cropping dominates the croplands. The shortened crop growth duration would consequently reduce crop productivity. The most significant decreases would be 27-31, 6-20, and 7-22% for the late crop in the double-rice rotation, wheat in the winter wheat-rice rotation, and single maize, respectively. However, our projection analysis also showed that the negative effects of the warming climate could be compensated for by stabilizing the growth duration of the crops via improvement in crop cultivars. In this case, the productivity of rice, wheat, and maize in the 2040s would increase by 4-16, 31-38, and 11-12%, respectively. Our modeling results implied that the possibility of securing future food production exists by adopting proper adaptation options in China.

  3. Climate Variability and Yields of Major Staple Food Crops in Northern Ghana

    2012-12-01

    Climate variability, the short-term fluctuations in average weather conditions, and agriculture affect each other. Climate variability affects the agroecological and growing conditions of crops and livestock, and is recently believed to be the greatest impediment to the realisation of the first Millennium Development Goal of reducing poverty and food insecurity in arid and semi-arid regions of developing countries. Conversely, agriculture is a major contributor to climate variability and change by emitting greenhouse gases and reducing the agroecology's potential for carbon sequestration. What however, is the empirical evidence of this inter-dependence of climate variability and agriculture in Sub-Sahara Africa? In this paper, we provide some insight into the long run relationship between inter-annual variations in temperature and rainfall, and annual yields of the most important staple food crops in Northern Ghana. Applying pooled panel data of rainfall, temperature and yields of the selected crops from 1976 to 2010 to cointegration and Granger causality models, there is cogent evidence of cointegration between seasonal, total rainfall and crop yields; and causality from rainfall to crop yields in the Sudano-Guinea Savannah and Guinea Savannah zones of Northern Ghana. This suggests that inter-annual yields of the crops have been influenced by the total mounts of rainfall in the planting season. Temperature variability over the study period is however stationary, and is suspected to have minimal effect if any on crop yields. Overall, the results confirm the appropriateness of our attempt in modelling long-term relationships between the climate and crop yield variables.

  4. Antiviral activity of α-helical stapled peptides designed from the HIV-1 capsid dimerization domain

    Directory of Open Access Journals (Sweden)

    Cowburn David

    2011-05-01

    Full Text Available Abstract Background The C-terminal domain (CTD of HIV-1 capsid (CA, like full-length CA, forms dimers in solution and CTD dimerization is a major driving force in Gag assembly and maturation. Mutations of the residues at the CTD dimer interface impair virus assembly and render the virus non-infectious. Therefore, the CTD represents a potential target for designing anti-HIV-1 drugs. Results Due to the pivotal role of the dimer interface, we reasoned that peptides from the α-helical region of the dimer interface might be effective as decoys to prevent CTD dimer formation. However, these small peptides do not have any structure in solution and they do not penetrate cells. Therefore, we used the hydrocarbon stapling technique to stabilize the α-helical structure and confirmed by confocal microscopy that this modification also made these peptides cell-penetrating. We also confirmed by using isothermal titration calorimetry (ITC, sedimentation equilibrium and NMR that these peptides indeed disrupt dimer formation. In in vitro assembly assays, the peptides inhibited mature-like virus particle formation and specifically inhibited HIV-1 production in cell-based assays. These peptides also showed potent antiviral activity against a large panel of laboratory-adapted and primary isolates, including viral strains resistant to inhibitors of reverse transcriptase and protease. Conclusions These preliminary data serve as the foundation for designing small, stable, α-helical peptides and small-molecule inhibitors targeted against the CTD dimer interface. The observation that relatively weak CA binders, such as NYAD-201 and NYAD-202, showed specificity and are able to disrupt the CTD dimer is encouraging for further exploration of a much broader class of antiviral compounds targeting CA. We cannot exclude the possibility that the CA-based peptides described here could elicit additional effects on virus replication not directly linked to their ability to bind

    In the steel industry, though the investment in isotope-equipped measuring instruments is small as compared with that in machinery, they play important role in the moisture measurement in sintering and blast furnaces, the thickness measurement in rolling process and others in automatic control systems. The economic aspect of the isotope-equipped measuring instruments is described on the basis of the practices in Kimitsu Works of Nippon Steel Corporation: distribution of such instruments, evaluation of economic effects, usefulness evaluation in view of raising the accuracy, and usefulness evaluation viewed from the failure of the isotope instruments. The evaluation of economic effects was made under the premise that the isotope-equipped measuring instruments are not employed. Then, the effects of raising the accuracy are evaluated for a γ-ray plate thickness gauge and a neutron moisture gauge for coke in a blast furnace. Finally, the usefulness was evaluated, assuming possible failure of the isotope-equipped measuring instruments. (J.P.N.)

    A system for the automatic evaluation of interference patterns has been developed. After digitizing the interferograms from classical and holografic interferometers with a television digitizer and performing different picture enhancement operations the fringe loci are extracted by use of a floating-threshold method. The fringes are numbered using a special scheme after the removal of any fringe disconnections which might appear if there was insufficient contrast in the interferograms. The reconstruction of the object function from the numbered fringe field is achieved by a local polynomial least-squares approximation. Applications are given, demonstrating the evaluation of interferograms of supersonic flow fields and the analysis of holografic interferograms of car-tyres.

  8. Automatic readout micrometer

    Science.gov (United States)

    Lauritzen, T.

    A measuring system is described for surveying and very accurately positioning objects with respect to a reference line. A principle use of this surveying system is for accurately aligning the electromagnets which direct a particle beam emitted from a particle accelerator. Prior art surveying systems require highly skilled surveyors. Prior art systems include, for example, optical surveying systems which are susceptible to operator reading errors, and celestial navigation-type surveying systems, with their inherent complexities. The present invention provides an automatic readout micrometer which can very accurately measure distances. The invention has a simplicity of operation which practically eliminates the possibilities of operator optical reading error, owning to the elimination of traditional optical alignments for making measurements. The invention has an extendable arm which carries a laser surveying target. The extendable arm can be continuously positioned over its entire length of travel by either a coarse of fine adjustment without having the fine adjustment outrun the coarse adjustment until a reference laser beam is centered on the target as indicated by a digital readout. The length of the micrometer can then be accurately and automatically read by a computer and compared with a standardized set of alignment measurements. Due to its construction, the micrometer eliminates any errors due to temperature changes when the system is operated within a standard operating temperature range.

    The restoration of the digestive tract by performing an esophago-jejunal anastomosis (EJA) is a crucial step of the total gastric and distal esophagus surgical resection for esophago-gastric junction (EGJ) cancer. We have already ideated and tested on a cadaver model an innovative technique which could be useful to minimize the risk of complications related to the phase of securing the anvil of the circular stapler prior to perform the EJA. This surgical technique was derived from the well-known "double-stapling Knight and Griffen" one that was described for the rectal resection. We used the following described technique in 20 patients with EGJ cancer and it is efficient, reliable, safe, easy to learn and easy to perform. From August 2014 to May 2015, 20 patients (14 male and 6 female) underwent surgery for esophagogastric junction cancer: In all patients a distal esophageal resection and total gastrectomy was performed. Through the trans-hiatal access, the free margins of the esophageal stump were suspended and the anvil of a circular stapler on a new dedicated and registered support bar was inserted into the lumen. Subsequently, the linear suturing stapler is closed over the bar and then fired to suture the distal stump of the esophagus; after the confirmation of a negative margin, the bar is retracted and the push-rod of the anvil is pulled out through the linear suture. Finally, the anastomosis is performed with the classic technique by using a circular stapler. No postoperative mortality occurred; postoperative course has been uneventful for 18 patients. One patient developed anastomotic fistula that has been treated conservatively with endoscopic prothesis, removed after 20 days. One patient developed in 3 POD myocardial infarction Mean Hospital stay has been 14 days (range 7-20 days). The aim of our new procedure is the insertion the anvil of a common circular stapler without handsewn securing; this is to reduce the technical difficulties related to the hand

    Yam (Dioscorea spp.) is a tuberous staple food crop of major importance in the sub-Saharan savannas of West Africa. Optimal yields commonly are obtained only in the first year following slash-and-burn in the shifting cultivation systems. It appears that the yield decline in subsequent years is not merely caused by soil nutrient depletion but might be due to a loss of the beneficial soil microflora, including arbuscular mycorrhizal fungi (AMF), associated with tropical "tree-aspect" savannas and dry forests that are the natural habitats of the wild relatives of yam. Our objective was to study the AMF communities of natural savannas and adjacent yam fields in the Southern Guinea savanna of Benin. AMF were identified by morphotyping spores in the soil from the field sites and in AMF trap cultures with Sorghum bicolor and yam (Dioscorea rotundata and Dioscorea cayenensis) as bait plants. AMF species richness was higher in the savanna than in the yam-field soils (18-25 vs. 11-16 spp.), but similar for both ecosystems (29-36 spp.) according to the observations in trap cultures. Inoculation of trap cultures with soil sampled during the dry season led to high AMF root colonization, spore production, and species richness (overall 45 spp.) whereas inoculation with wet-season soil was inefficient (two spp. only). The use of D. cayenensis and D. rotundata as baits yielded 28 and 29 AMF species, respectively, and S. bicolor 37 species. AMF root colonization, however, was higher in yam than in sorghum (70-95 vs. 11-20%). After 8 months of trap culturing, the mycorrhizal yam had a higher tuber biomass than the nonmycorrhizal controls. The AMF actually colonizing D. rotundata roots in the field were also studied using a novel field sampling procedure for molecular analyses. Multiple phylotaxa were detected that corresponded with the spore morphotypes observed. It is, therefore, likely that the legacy of indigenous AMF from the natural savanna plays a crucial role for yam

In this paper, an automatic detection method was developed which is composed of three parts in the automatic detection: the shape of LED lamps, the color of LED lamps, and defect spots inside the lamps. More than hundreds of fascias were detected with the automatic detection algorithm. The speed of the algorithm is quite fast and satisfied with the real-time request of the system. Further, the detection result was demonstrated to be stable and accurate.

    Automatic sets D part of Z m are characterized by having a finite number of decimations. They are equivalently generated by fixed points of certain substitution systems, or by certain finite automata. As examples, two-dimensional versions of the Thue-Morse, Baum-Sweet, Rudin-Shapiro and paperfolding sequences are presented. We give a necessary and sufficient condition for an automatic set D part of Z m to be a Delone set in R m . The result is then extended to automatic sets that are defined as fixed points of certain substitutions. The morphology of automatic sets is discussed by means of examples

    Postoperative pancreatic fistula formation remains a source of significant morbidity following distal pancreatectomy. The aim of this study was to evaluate the rate of clinically significant fistulas (International Study Group on Pancreatic Fistula grade B and grade C) after distal pancreatectomy using a fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure. Seventy-five patients underwent distal pancreatectomy at our institution between January 2005 and March 2014. A fibrinogen/thrombin-based collagen fleece was applied to the staple line of the pancreas before stapling. Twenty-six patients (34.7%) developed a pancreatic fistula, 8 patients (10.7%) developed a grade B fistula, and no patients developed a grade C fistula. The duration of the drain was significantly different in patients with or without a pancreatic fistula (8.0 ± 4.5 vs. 5.4 ± 1.3 days, P = .0003). Histological analysis showed that there was a tight covering with the fibrinogen/thrombin-based collagen fleece. The fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure has low rates of fistula formation and provides a safe alternative to the conventional stapled technique in distal pancreatectomy. © The Author(s) 2015.

    We investigated surgical results of staple line coverage with a polyglycolic acid sheet plus pleural abrasion by thoracoscopic surgery for treating primary spontaneous pneumothorax in young patients. Forty-seven patients younger than 40 years underwent 48 thoracoscopic surgical procedures for spontaneous pneumothorax at the Division of Thoracic Surgery, Department of Surgery, Nippon Medical School, from May 2007 through August 2010. All patients underwent thoracoscopic bullectomy with stapling devices and pleural abrasion performed with a gauze sponge held by forceps until the pleura became petechial. Finally, the staple line was covered with a polyglycolic acid sheet (10 × 10 cm). No fibrin glue was used. We investigated both short-time results after surgery and the postoperative recurrence of pneumothorax. There was no operative mortality or morbidity, such as air leakage from staple lines or hemorrhage due to pleural abrasion. Pneumothorax recurred after surgery in 3 cases. In 2 cases, neither re-operation nor tube thoracostomy was necessary because intrapleural adhesions allowed only partial collapse of the lung. One patient underwent re-operation for an overlooked bulla facing the diaphragm in left lower lobe of the lung 2 days after the first operation. The rate of freedom from pneumothorax 4 years after surgery was 94%. Staple line coverage with a polyglycolic acid sheet plus pleural abrasion by thoracoscopic surgery is a useful method for preventing morbidity and the postoperative recurrence of pneumothorax.

    To describe stapled 1-stage functional end-to-end intestinal anastomosis for treatment of small intestinal obstruction in dogs and evaluate outcome when the technique is performed by nonexpert surgeons after limited training in the technique. Case series. Dogs (n=30) with intestinal lesions requiring an enterectomy. Stapled 1-stage functional end-to-end anastomosis and resection using a GIA-60 and a TA-55 stapling devices were performed under supervision of senior residents and faculty surgeons by junior surgeons previously trained in the technique on pigs. Procedure duration and technical problems were recorded. Short-term results were collected during hospitalization and at suture removal. Long-term outcome was established by clinical and ultrasonographic examinations at least 2 months after surgery and from written questionnaires, completed by owners. Mean±SD procedure duration was 15±12 minutes. Postoperative recovery was uneventful in 25 dogs. One dog had anastomotic leakage, 1 had a localized abscess at the transverse staple line, and 3 dogs developed an incisional abdominal wall abscess. No long-term complications occurred (follow-up, 2-32 months). Stapled 1-stage functional end-to-end anastomosis and resection is a fast and safe procedure in the hand of nonexpert but trained surgeons. © Copyright 2011 by The American College of Veterinary Surgeons.

    Automatic knowledge extraction from music signals is a key component for most music organization and music information retrieval systems. In this paper, we consider the problem of instrument modelling and instrument classification from the rough audio data. Existing systems for automatic instrument...... classification operate normally on a relatively large number of features, from which those related to the spectrum of the audio signal are particularly relevant. In this paper, we confront two different models about the spectral characterization of musical instruments. The first assumes a constant envelope...... on a large database of real instrument recordings show that the first model offers a more satisfactory characterization, and therefore MFCCs should be preferred to HR for instrument modelling/classification....

    The quantitative determination of metallographic parameters is analysed through the description of Micro-Videomat automatic image analysis system and volumetric percentage of perlite in nodular cast irons, porosity and average grain size in high-density sintered pellets of UO 2 , and grain size of ferritic steel. Techniques adopted are described and results obtained are compared with the corresponding ones by the direct counting process: counting of systematic points (grid) to measure volume and intersections method, by utilizing a circunference of known radius for the average grain size. The adopted technique for nodular cast iron resulted from the small difference of optical reflectivity of graphite and perlite. Porosity evaluation of sintered UO 2 pellets is also analyzed [pt

    Extruded aluminum-clad uranium-aluminum alloy fuel tubes must pass many quality control tests before irradiation in Savannah River Plant nuclear reactors. Nondestructive test equipment has been built to automatically detect high and low density areas in the fuel tubes using x-ray absorption techniques with a video analysis system. The equipment detects areas as small as 0.060-in. dia with 2 percent penetrameter sensitivity. These areas are graded as to size and density by an operator using electronic gages. Video image enhancement techniques permit inspection of ribbed cylindrical tubes and make possible the testing of areas under the ribs. Operation of the testing machine, the special low light level television camera, and analysis and enhancement techniques are discussed

  2. AUTOMATIC ARCHITECTURAL STYLE RECOGNITION

    Full Text Available Procedural modeling has proven to be a very valuable tool in the field of architecture. In the last few years, research has soared to automatically create procedural models from images. However, current algorithms for this process of inverse procedural modeling rely on the assumption that the building style is known. So far, the determination of the building style has remained a manual task. In this paper, we propose an algorithm which automates this process through classification of architectural styles from facade images. Our classifier first identifies the images containing buildings, then separates individual facades within an image and determines the building style. This information could then be used to initialize the building reconstruction process. We have trained our classifier to distinguish between several distinct architectural styles, namely Flemish Renaissance, Haussmannian and Neoclassical. Finally, we demonstrate our approach on various street-side images.

    In order to investigate the feasibility of automatic surveying methods in a more systematic manner, the PEP organization signed a contract in late 1975 for TRW Systems Group to undertake a feasibility study. The completion of this study resulted in TRW Report 6452.10-75-101, dated December 29, 1975, which was largely devoted to an analysis of a survey system based on an Inertial Navigation System. This PEP note is a review and, in some instances, an extension of that TRW report. A second survey system which employed an ''Image Processing System'' was also considered by TRW, and it will be reviewed in the last section of this note. 5 refs., 5 figs., 3 tabs

    RFS or Regles Fondamentales de Surete (Basic Safety Rules) applicable to certain types of nuclear facilities lay down requirements with which compliance, for the type of facilities and within the scope of application covered by the RFS, is considered to be equivalent to compliance with technical French regulatory practice. The object of the RFS is to take advantage of standardization in the field of safety, while allowing for technical progress in that field. They are designed to enable the operating utility and contractors to know the rules pertaining to various subjects which are considered to be acceptable by the Service Central de Surete des Installations Nucleaires, or the SCSIN (Central Department for the Safety of Nuclear Facilities). These RFS should make safety analysis easier and lead to better understanding between experts and individuals concerned with the problems of nuclear safety. The SCSIN reserves the right to modify, when considered necessary, any RFS and specify, if need be, the terms under which a modification is deemed retroactive. The aim of this RFS is to define the type, location and operating conditions for seismic instrumentation needed to determine promptly the seismic response of nuclear power plants features important to safety to permit comparison of such response with that used as the design basis

    The feasibility and safety of laparoscopic and robotic Roux-en-Y gastric bypass (RRYGB) have been established. To evaluate the cost-effectiveness of robotic surgery we compared the hospital charges for robotic, laparoscopic stapled (SRYGB), and laparoscopic handsewn Roux-en-Y gastric bypass (HRYGB) at our institution. One hundred thirty-five consecutive patients undergoing Roux-en-Y gastric bypass at Stanford University Medical Center by handsewn, stapled or robotic techniques from 1 July 2005 to 31 December 2005 were evaluated. Medical records of these patients were retrospectively reviewed and the following variables were collected and analyzed: age, gender, body mass index (BMI), number of preoperative comorbidities, length of stay (LOS), operating and anesthesia times, postoperative complications, mortality, professional fees, and hospital and total charges. Twenty-one RRYGB, 78 SRYGB, and 36 HRYGB were performed during the study period. Comparison of the above three groups demonstrated no statistically significant differences in age, gender, BMI, number of preoperative comorbidities, LOS, operating and anesthesia times, postoperative complications, mortality or professional fees. Total charges were higher for RRYGB (US $77,820) when compared with SRYGB (US $66,153) but not when compared with HRYGB (US $68,814). RRYGB higher hospital charges resulted in higher total charges when compared with SRYGB and HRYGB. These differences do not reflect actual cost to the hospital.

    To identify risk factors for dehiscence in stapled functional end-to-end anastomoses (SFEEA) in dogs. Retrospective case series. Dogs (n = 53) requiring an enterectomy. Medical records from a single institution for all dogs undergoing an enterectomy (2001-2012) were reviewed. Surgeries were included when gastrointestinal (GIA) and thoracoabdominal (TA) stapling equipment was used to create a functional end-to-end anastomosis between segments of small intestine or small and large intestine in dogs. Information regarding preoperative, surgical, and postoperative factors was recorded. Anastomotic dehiscence was noted in 6 of 53 cases (11%), with a mortality rate of 83%. The only preoperative factor significantly associated with dehiscence was the presence of inflammatory bowel disease (IBD). Surgical factors significantly associated with dehiscence included the presence, duration, and number of intraoperative hypotensive periods, and location of anastomosis, with greater odds of dehiscence in anastomoses involving the large intestine. IBD, location of anastomosis, and intraoperative hypotension are risk factors for intestinal anastomotic dehiscence after SFEEA in dogs. Previously suggested risk factors (low serum albumin concentration, preoperative septic peritonitis, and intestinal foreign body) were not confirmed in this study. © Copyright 2015 by The American College of Veterinary Surgeons.

    Staple line leakage after bariatric surgery can be treated by endoscopic placement of a self-expandable stent. The success rate of stent placement is generally high, but migration is a frequent adverse event that hampers successful treatment. The Niti-S Beta stent is a fully covered double-bump stent that was specifically designed to prevent migration. This study aimed to evaluate the effectiveness and adverse event rate of the Niti-S Beta stent. A retrospective study was performed in three high-volume bariatric centers. All consecutive patients between 2009 and 2016 who underwent placement of a Beta stent for staple line leakage were included. Primary outcome was resolution of the leakage; secondary outcome was the adverse event rate including migration. Thirty-eight patients were included. Twenty-five (66%) had resolution of the leakage. Success rate was higher in patients who were treated with implantation of a Beta stent as initial treatment (100%) than in patients who were treated with a stent after revisional surgery had failed (55%, p = 0.013). Migration occurred in 12 patients (32%). There were two severe adverse events requiring surgical intervention, including a bleeding from an aorto-esophageal fistula. The success rate and the migration rate of the Beta stent seem comparable to other stents in this retrospective study. Despite the novel double-bump structure of the stent, the migration rate does not seem to be decreased.

    The prevalence of type 2 diabetes has been reaching epidemic proportions across the globe, affecting low/middle-income and developed countries. Two main contributors to this burden are the reduction in mortality from infectious conditions and concomitant negative changes in lifestyles, including diet. We aimed to depict the current state of type 2 diabetes worldwide in light of the undergoing epidemiologic and nutrition transition, and to posit that a key factor in the nutrition transition has been the shift in the type and processing of staple foods, from less processed traditional foods to highly refined and processed carbohydrate sources. We showed data from 11 countries participating in the Global Nutrition and Epidemiologic Transition Initiative, a collaborative effort across countries at various stages of the nutrition-epidemiologic transition whose mission is to reduce diabetes by improving the quality of staple foods through culturally-appropriate interventions. We depicted the epidemiologic transition using demographic and mortality data from the World Health Organization, and the nutrition transition using data from the Food and Agriculture Organization food balance sheets. Main staple foods (maize, rice, wheat, pulses, and roots) differed by country, with most countries undergoing a shift in principal contributors to energy consumption from grains in the past 50 years. Notably, rice and wheat products accounted for over half of the contribution to energy consumption from staple grains, while the trends for contribution from roots and pulses generally decreased in most countries. Global Nutrition and Epidemiologic Transition Initiative countries with pilot data have documented key barriers and motivators to increase intake of high-quality staple foods. Global research efforts to identify and promote intake of culturally-acceptable high-quality staple foods could be crucial in preventing diabetes. These efforts may be valuable in shaping future research

The mean concentrations of elements determined in the two staple foods are presented and compared with the mean concentrations published in the literature.

  12. Automatic exposure for xeromammography

    Aichinger, H.

    1977-01-01

    During mammography without intensifying screens, exposure measurements are carried out behind the film. It is, however, difficult to construct an absolutely shadow-free ionization chamber of adequate sensitivity working in the necessary range of 25 to 50 kV. Repeated attempts have been made to utilize the advantages of automatic exposure for xero-mammography. In this case also the ionization chamber was placed behind the Xerox plate. Depending on tube filtration, object thickness and tube voltage, more than 80%, sometimes even 90%, of the radiation is absorbed by the Xerox plate. Particularly the characteristic Mo radiation of 17.4 keV and 19.6 keV is almost totally absorbed by the plate and cannot therefore be registered by the ionization chamber. This results in a considerable dependence of the exposure on kV and object thickness. Dependence on tube voltage and object thickness have been examined dosimetrically and spectroscopically with a Ge(Li)-spectrometer. Finally, the successful use of a shadow-free chamber is described; this has been particularly adapted for xero-mammography and is placed in front of the plate. (orig) [de

    Full Text Available To study the associations between maternal consumption of non-staple food in the first trimester and risk of neural tube defects (NTDs in offspring. Data collected from a hospital-based case-control study conducted between 2006 and 2008 in Shandong/Shanxi provinces including 459 mothers with NTDs-affected births and 459 mothers without NTDs-affected births. Logistic regression models were used to examine the associations between maternal consumption of non-staple food in the first trimester and risk of NTDs in offspring. The effects were evaluated by odds ratio (OR and 95% confidence intervals (95% CIs with SAS9.1.3.software. Maternal consumption of milk, fresh fruits and nuts in the first trimester were protective factors for total NTDs. Compared with consumption frequency of ˂1 meal/week, the ORs for milk consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.50 (95% CI: 0.28–0.88, 0.56 (0.32–0.99, and 0.59 (0.38–0.90, respectively; the ORs for fresh fruits consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.29 (95% CI: 0.12–0.72, 0.22 (0.09–0.53, and 0.32 (0.14–0.71, respectively; the ORs for nuts consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.60 (95% CI: 0.38–0.94, 0.49 (0.31–0.79, and 0.63 (0.36–1.08, respectively. Different effects of above factors on NTDs were found for subtypes of anencephaly and spina bifida. Maternal non-staple food consumption of milk, fresh fruits and nuts in the first trimester was associated with reducing NTDs risk in offspring.

    2006-01-01

    Virtual instruments based on Monte-Carlo techniques are now integral part of novel instrumentation development and the existing codes (McSTAS and Vitess) are extensively used to define and optimise novel instrumental concepts. Neutron spectrometers, however, involve a large number of parameters and their optimisation is often a complex and tedious procedure. Artificial intelligence algorithms are proving increasingly useful in such situations. Here, we present an automatic, reliable and scalable numerical optimisation concept based on the canonical genetic algorithm (GA). The algorithm was used to optimise the 3D magnetic field profile of the NSE spectrometer SPAN, at the HMI. We discuss the potential of the GA which combined with the existing Monte-Carlo codes (Vitess, McSTAS, etc.) leads to a very powerful tool for automated global optimisation of a general neutron scattering instrument, avoiding local optimum configurations

    This presentation is a report of the studies carried out by the Work Group on Functioning Safety of Programmable Automatic Control Devices and by the Group for Prevention Studies (GEP) from the CEA. The objective of these groups is to evaluate the methods which could be used to estimate the functioning safety of control and instrumentation systems involved in the Important Elements for Safety (EIS) of the Basic Nuclear Installations (INB) of the CEA, and also to carry out a qualification of automatic control devices. Norms, protocols and tools for the evaluation are presented. The problem comprises two aspects: the evaluation of fault avoidance techniques and the evaluation of fault control techniques used during the conceiving. For the fault avoidance techniques, the quality assurance organization, the environment tests, and the software quality plans are considered. For the fault control techniques, the different available tools and fault injection models are analysed. The results of an analysis carried out with the DEF.I tool from the National Institute for Research and Safety (INRS) are reported. (J.S.). 23 refs

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    Anastomotic leakage (AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection (LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR.

    Parastomal hernia is one of the most common stoma related complication, with the correlated risk of incarceration, obstruction, and strangulation. The incidence is high (30-50%) and depends on the length of follow up. Different surgical options for repairing are defective with a 25-70% failure and recurrence rate. Prevention of parastomal hernia with mesh reinforcement seems to be effective. Three available trials are recruiting patients: Prism (with matrix porcine prothesis), Prevent (with preperitoneal polypropylene mesh), and the stapled polypropylene mesh stoma reinforcement technique (SMART). We performed the SMART procedure in six patients undergoing definitive colostomy. Our cases show that the procedure is rapid (duration range 15-20 minutes), cost effective (500 euro), and safe (in our experience, there are no post-surgical complications that are procedure-related). A long term follow-up and a higher number of patients will give us confirmation of the initial hopeful results.

    Of all the complications associated with colorectal surgery, the most devastating and constant, despite all techniques being performed properly is anastomotic leakage, especially in left colon and rectal resections with rates as high as 50% when the rectum is involved. In 2005, our center published the preliminary experience with the use of linear staple line reinforcement for colon surgery. The purpose of this paper is to present a series of cases using a new conformation of bioabsorbable reinforcement for circular staplers in 5 patients, 2 patients with rectal cancer, 2 patients with diverticular disease, and 1 patient with sigmoid cancer. These initial data are very promising and has encouraged us to continue using this device on further patients.

    Full Text Available Our paper focuses on the graphical analysis domain. We propose an automatic image recognition technique. This approach consists of two main pattern recognition steps. First, it performs an image feature extraction operation on an input image set, using statistical dispersion features. Then, an unsupervised classification process is performed on the previously obtained graphical feature vectors. An automatic region-growing based clustering procedure is proposed and utilized in the classification stage.

    A high incidence of anastomotic leakage (37.5%) is reported after low anterior rectal resection (LAR) and circular double-stapled anastomosis without protective ileostoma. Since the pathomechanism of anastomosis leakage is still unclear, a suitable animal model would be most desirable. The objective was to assess the incidence of clinically apparent and inapparent leakage after LAR in pigs (n = 20). Endpoints were radiological, clinical, macroscopic, and histologic proof of anastomotic leakage on the 9th postoperative day. Integrity of anastomosis was assessed by double-contrast barium examination on 9th postoperative day. Animals were sacrificed and anastomoses were resected for histopathological investigation. In case of earlier clinical apparent anastomotic leakage, radiologic double-contrast barium was performed immediately. LAR with a circular double-stapled anastomosis without protective ileostoma was performed in 20 pigs (m:f = 8:12). Length of resection was 10-20 cm, anastomosis was performed 7 cm ab ano. Five animals (25%) developed clinical apparent anastomotic leakage (no appetite, fever, inactivity, tachypnea, discomfort, pain) between the 6th (n = 1) and 9th (n = 4) postoperative day, proven by double-contrast barium radiographs. Additionally in 1 animal clinical inapparent anastomotic insufficiency was observed radiologically. Total rate of leakage was 30% (n = 6). These results were confirmed by leucocytosis, low potassium levels, in two cases high ALT and AST and local peritonitis in all cases. Including one additional case of clinical inapparent leakage, total rate of anastomotic leakage was 30% (6/20). Thus we managed to establish a new experimental model of anastomotic leakage after low rectal resection comparable to the human situation.

    HarvestPlus, part of the Consultative Group on Internation Agriculture research (CGIAR) Program on Agriculture for Nutrition and Health (A4NH) uses conventional plant breeding techniques to develop staple food crops that are rich in micronutrients, a food-based approach to reduce micronutrient malnutrition known as biofortification. The nutritional breeding targets are established based on the food intake of target populations, nutrient losses during storage and processing and bioavailability. This review collates the evidence on the retention of provitamin A carotenoid (pVAC) after processing, cooking, and storing of the staple crops targeted for pVAC biofortification: cassava, maize, and sweet potato. Sun drying was more detrimental to the pVAC levels (27–56% retention) in cassava than shade (59%) or oven (55–91%) drying, while the pVAC retention levels (66–96%) in sweet potato were not significantly different among the various drying methods. Overall, boiling and steaming had higher pVAC retention (80–98%) compared to baking (30–70%) and frying (18–54%). Gari, the most frequently consumed form of cassava in West Africa had the lowest pVAC retention (10–30%). The pVAC retention of maize grain and cassava and sweet potato flour reached levels as low as 20% after 1–4 months of storage and was highly dependent on genotype. Therefore, we recommend that an evaluation of the pVAC degradation rate among different genotypes be performed before a high pVAC crop is promoted. PMID:24915386

    Pelvic floor dysfunction is common in women after childbirth and precise segmentation of magnetic resonance images (MRI) of the pelvic floor may facilitate diagnosis and treatment of patients. However, because of the complexity of its structures, manual segmentation of the pelvic floor is challenging and suffers from high inter and intra-rater variability of expert raters. Multiple template fusion algorithms are promising segmentation techniques for these types of applications, but they have been limited by imperfections in the alignment of templates to the target, and by template segmentation errors. A number of algorithms sought to improve segmentation performance by combining image intensities and template labels as two independent sources of information, carrying out fusion through local intensity weighted voting schemes. This class of approach is a form of linear opinion pooling, and achieves unsatisfactory performance for this application. We hypothesized that better decision fusion could be achieved by assessing the contribution of each template in comparison to a reference standard segmentation of the target image and developed a novel segmentation algorithm to enable automatic segmentation of MRI of the female pelvic floor. The algorithm achieves high performance by estimating and compensating for both imperfect registration of the templates to the target image and template segmentation inaccuracies. A local image similarity measure is used to infer a local reliability weight, which contributes to the fusion through a novel logarithmic opinion pooling. We evaluated our new algorithm in comparison to nine state-of-the-art segmentation methods and demonstrated our algorithm achieves the highest performance.

    A robust identification of the instrument currently used by the surgeon is crucial for the automatic modeling and analysis of surgical procedures. Various approaches for intra-operative surgical instrument identification have been presented, mostly based on radio-frequency identification (RFID) or endoscopic video analysis. A novel approach is to identify the instruments on the instrument table of the scrub nurse with a combination of video and weight information. In a previous article, we successfully followed this approach and applied it to multiple instances of an ear, nose and throat (ENT) procedure and the surgical tray used therein. In this article, we present a metric for the suitability of the instruments of a surgical tray for identification by video and weight analysis and apply it to twelve trays of four different surgical domains (abdominal surgery, neurosurgery, orthopedics and urology). The used trays were digitized at the central sterile services department of the hospital. The results illustrate that surgical trays differ in their suitability for the approach. In general, additional weight information can significantly contribute to the successful identification of surgical instruments. Additionally, for ten different surgical instruments, ten exemplars of each instrument were tested for their weight differences. The samples indicate high weight variability in instruments with identical brand and model number. The results present a new metric for approaches aiming towards intra-operative surgical instrument detection and imply consequences for algorithms exploiting video and weight information for identification purposes.

    To evaluate the outcome of stapled versus sutured colo-rectal anastomosis after low anterior resection of mid-rectal carcinoma. A prospective study of fifty patients who underwent colo-rectal anastomosis following low anterior resection (LAR) of T2 mid-rectal cancers at the Egyptian National Cancer Institute during the time period from June 2010 to June 2013 was conducted. Classification was into two groups; a stapled anastomosis group I (25 patients) and a hand-sewn anastomosis group II (25 patients). All operations are evaluated regarding intra-operative complications such as anastomotic line bleeding, visceral injuries or major blood loss. The anastomotic time and operative time are documented for each operation. All patients are evaluated post-operatively for anastomotic leakage (AL), wound infection and ileus. The distance of the tumor from the anal verge was 9.6 ± 2.0 cm in group I and 9.9 ± 2.4 cm in group II. The mean operative time was 191.5 ± 16.2 min in the stapled group and 208 ± 18.6 min in the sutured group (p=0.002). The mean anastomotic times were 9.0 ± 1.9 min and 19.7 ± 12.2 min (p=0.001). Anastomotic leakage developed in three (12.0%) patients in the stapled group and in four (16.0%) patients in the sutured group (p=1.000). Post-operative ileus was observed in 3 patients in group I and one patient in group II. Wound infection developed in three (12.0%) patients in the stapled group and four (16.0%) patients in the sutured group (p=1.000). Colo-rectal anastomosis after low anterior resection for mid rectal carcinoma can be conducted safely either by stapling or hand-sewn techniques; however the stapling technique showed shorter anastomotic and operative times with no significant advantages regarding intra- or post-operative complications or hospital stay.

    With the increasingly stricter control of pollutant emission in China, the on-line automatic monitoring of water quality is particularly urgent. The chemical oxygen demand (COD) is a comprehensive index to measure the contamination caused by organic matters, and thus it is taken as one important index of energy-saving and emission reduction in China’s “Twelve-Five” program. So far, the COD on-line automatic monitoring instrument has played an important role in the field of sewage monitoring. This paper reviews the existing methods to achieve on-line automatic monitoring of COD, and on the basis, points out the future trend of the COD on-line automatic monitoring instruments.

    Local postoperative care and burn wound management can present with a certain degree of difficulty in the pediatric population. While the use of skin staples as a method of skin graft fixation is a well-known, rapid and simple method, their removal can be painful and may necessitate some sedation or even general anesthesia. We studied in this article the advantages and economic value of using the cyanoacrylate glue as a fixation method for skin grafts. A comparative study was carried out from 2012 to 2016. Hundred and eighteen infants with burns up to 5% of total body surface area were included in the study. Seventy-two infants had split thickness skin grafts fixed with skin staples. Forty-six infants had split thickness skin grafts fixed with cyanoacrylate glue. We compared the quality of graft, the sedation used during the first postoperative dressing, the length of hospital stay, the amount of glue used and the presence of complications. There is a difference between the two groups studied in terms of age and total burn surface area. The rate of graft take was 100% in both groups. The first postoperative dressing was carried out without the use of powerful analgesia in the cyanoacrylate group, while it was necessary to use general anesthesia in 64% of the skin staples group. The average length of stay in hospital after skin grafting was 4.9 days for the cyanoacrylate glue versus 6.5 days in the skin staples group. No complications were noted in the 2 groups. The use of cyanoacrylate glue allows rapid fixation of skin grafts and avoid general anesthesia for postoperative cares. Subsequently the length of hospital stay is reduced within 25%. The medico-economic value of glue protocol is highly significant compared to skin staples, while having similar good results and without significant problems. Copyright © 2017 Elsevier Masson SAS.

    Although colonic surgery is performed with strict aseptic measures, some contamination is nearly impossible to avoid. In stapled anastomosis, the hole opened in the colon is minimum, just necessary for introducing the parts of the mechanical devices. In handsewn anastomosis, the colonic lumen is more exposed to the peritoneum, despite colonic occlusion with clamps while the suture is performed. A prospective, randomized study was performed between October 2009 and June 2011. Inclusion criteria were a diagnosis of right-sided colon cancer and having undergone an elective surgery with curative aims. The patients were divided into two groups: those patients undergoing a stapled ileocolonic anastomosis (group 1) and those undergoing a handsewn anastomosis (group 2). A microbiological sample was obtained from the peritoneal surface before opening the colon and after finishing the anastomosis in each group. Data were correlated with the wound infection and intra-abdominal infection rates. Eighty-four patients were included in the study: 42 patients in each group. There were two intra-abdominal abscesses (5 %) in each group (NS). Wound infection rate was 10 % in group 1 and 7 % in group 2 (NS). Mean operative time was 98.8 min in the stapled group and 105.2 min in the handsewn one (P = 0.013). Positive cultures were obtained in 79 % of the cases after stapled anastomosis and 73 % after handsewn ones (NS). Peritoneal contamination appears in over 70 % of cases after ileocolonic anastomosis. Significant differences in peritoneal contamination, wound infection, and intra-abdominal abscess between stapled and handsewn anastomoses could not be demonstrated.

    1978-10-01

    This manual describes and provides trouble-shooting aids for the Automatic Sample Changer electronics on the automatic beta counting system, developed by the Los Alamos Scientific Laboratory Group CNC-11. The output of a gas detector is shaped by a preamplifier, then is coupled to an amplifier. Amplifier output is discriminated and is the input to a scaler. An identification number is associated with each sample. At a predetermined count length, the identification number, scaler data plus other information is punched out on a data card. The next sample to be counted is automatically selected. The beta counter uses the same electronics as the prior count did, the only difference being the sample identification number and sample itself. This manual is intended as a step-by-step aid in trouble-shooting the electronics associated with positioning the sample, counting the sample, and getting the needed data punched on an 80-column data card

    Food fortification is a viable strategy to improve the nutritional status of populations. In Southeast Asia, recent growth and consolidation of the food industry provides an opportunity to explore whether certain widely consumed processed foods could contribute to micronutrient status if they are made with adequately fortified staples and condiments. To estimate the potential contribution certain processed foods can make to micronutrient intake in Southeast Asia if they are made with fortified staples and condiments; e.g., via the inclusion of iodized salt in various processed foods in the Philippines, fortified wheat flour in instant noodles in Indonesia, and fortified vegetable oil in biscuits in Vietnam. For Indonesia, the Philippines, and Vietnam, a review of consumption trends, relevant policies, and industry practices was conducted using publicly available sources,food industry market data and research reports, and oral communication. These informed the estimates of the proportion of the Recommended Nutrient Intake (RNI) that could be delivered via select processed foods. In the Philippines, Indonesia, and Vietnam, the processed food industry is not always required to use fortified staples and condiments. In the Philippines, dried salted fish with iodized salt would provide 64% to 85% of the iodine RNI for women of reproductive age and 107% to 141% of the iodine RNI for children 1 to 6 years of age. In Indonesia, a 75-g pack of instant noodles (a highly consumed product) with fortified wheat flour would provide 45% to 51% of the iron RNI for children 4 to 6 years of age and 10% to 11% of the iron RNI for women of reproductive age. In Vietnam, biscuits containing vegetable oil are increasingly popular. One 35-g biscuit serving with fortified vegetable oil would provide 13% to 18% of the vitamin A RNI for children 4 to 6 years of age and 12% to 17% of the vitamin A RNI for women of reproductive age. Ensuring that fortified staples and condiments such as flour

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    Full Text Available Laparoscopic sphincter-preserving low anterior resection for rectal cancer is a surgery demanding great skill. Immense efforts have been devoted to identifying factors that can predict operative difficulty, but the results are inconsistent.Our study was conducted to screen patients' factors to build models for predicting the operative difficulty using well controlled data.We retrospectively reviewed records of 199 consecutive patients who had rectal cancers 5-8 cm from the anal verge. All underwent laparoscopic sphincter-preserving low anterior resections with total mesorectal excision (TME and double stapling technique (DST. Data of 155 patients from one surgeon were utilized to build models to predict standardized endpoints (operative time, blood loss and postoperative morbidity. Data of 44 patients from other surgeons were used to test the predictability of the built models.Our results showed prior abdominal surgery, preoperative chemoradiotherapy, tumor distance to anal verge, interspinous distance, and BMI were predictors for the standardized operative times. Gender and tumor maximum diameter were related to the standardized blood loss. Temporary diversion and tumor diameter were predictors for postoperative morbidity. The model constructed for the operative time demonstrated excellent predictability for patients from different surgeons.With a well-controlled patient population, we have built a predictable model to estimate operative difficulty. The standardized operative time will make it possible to significantly increase sample size and build more reliable models to predict operative difficulty for clinical use.

  1. Predisposition to insulin resistance and obesity due to staple consumption of rice: Amylose content versus germination status.

    Full Text Available Type 2 diabetes is a metabolic disorder with established, well-defined precursors. Obesity and insulin resistance are amongst most important factors in predisposition to diabetes. Rice is a staple for about half the global population and its consumption has been strongly linked with diabetogenesis. We assert that tackling the prevalence of predisposing factors by modifying certain rice cultivars could reduce the global burden of obesity and insulin resistance, and by extension type 2 diabetes. Several rice cultivars with various properties were fed to nulliparous rats (five weeks old at the start of the experiment for 90 days. They were then returned to a diet of standard pellets and mated with males raised on a standard diet. The resulting pups and dams were investigated for obesity and insulin resistance markers. We found that germination did more to reduce predisposition to obesity and insulin resistance than high amylose content. The combined reducing effect of germination and high amylose content on predisposition to obesity and insulin resistance was greater than the sum of their independent effects. Polished (white rice with a low amylose content predisposed dams on a high-fat diet to markers of insulin resistance and obesity and this predisposition was inherited (in biochemical terms by their F1 offspring. Overall, the results suggest that harnessing the beneficial properties of germination and amylose in rice would reduce the burden of obesity and insulin resistance, which are known to be key risk factors for development of type 2 diabetes.

    Babassu (Orbignya phalerata), a palm-tree coconut fruit, mixed with mandioca (Manihot utilissima) is the staple food of people living in the endemic goiter area of Maranhao in Brazil, where goiter prevalence among schoolchildren was still 38% in 1986 despite an adequate iodine intake in most of the population. Therefore, the question arose as to whether or not the ingestion of babassu alone or mixed with mandioca contributed to the persistence of endemic goiter in this area of Brazil. In this investigation we examined the potential antithyroid effects of babassu and mandioca by means of in vivo studies in Sprague-Dawley rats, in vitro studies in porcine thyroid slices and using a purified porcine thyroid peroxidase (TPO) system. Samples of various edible parts of babassu and mandioca flour were homogenized and extracted in goitrogen-free water (GFW) for in vivo experiments, and in methanol (100 g/l), GFW or 0.06 mol/l phosphate buffer (pH 7.0) for in vitro experiments. The edible parts of babassu produced significant in vivo antithyroid effects (p < 0.05- < 0.001) in rats on a high iodine intake (14 micrograms I- day-1.rat-1), as well as distinct and reproducible antithyroid and anti-TPO activities in both in vitro systems, their action being similar to that of the thionamide-like antithyroid drugs propylthiouracil and methimazole.(ABSTRACT TRUNCATED AT 250 WORDS)

    The objective of this article is to systematically analyze the randomized, controlled trials comparing the effectiveness of suture anastomosis (SUA) versus stapled anastomosis (STA) in patients undergoing ileostomy closure. Randomized, controlled trials comparing the effectiveness of SUA versus STA in patients undergoing ileostomy closure were analyzed using RevMan(®), and combined outcomes were expressed as odds risk ratio (OR) and standardized mean difference (SMD). Four randomized, controlled trials that recruited 645 patients were retrieved from electronic databases. There were 327 patients in the STA group and 318 patients in the SUA group. There was significant heterogeneity among included trials. Operative time (SMD -1.02; 95 % CI -1.89, -0.15; z = 2.29; p infection, reoperation and readmission were similar following STA and SUA in patients undergoing ileostomy closure. Length of hospital stay was also similar between STA and SUA groups. In ileostomy closure, STA was associated with shorter operative time and lower risk of postoperative small bowel obstruction. However, STA and SUA were similar in terms of anastomotic leak, surgical site infection, readmission, reoperations and length of hospital stay.

    Among Swedish children of 0-12 years old, we investigated various food allergy-related exposures associated with health-related quality of life using a food allergy-specific questionnaire among children allergic to the staple foods cow's milk, hen's egg and/or wheat, and contextualised worse food allergy-associated health-related quality of life using a generic questionnaire versus controls. In total, 85 children with objectively diagnosed allergy to the staple foods were included as cases, and 94 children matched for age and sex were included as controls. We administered a food allergy-specific parent-completed questionnaire originally developed by EuroPrevall to cases only, and a generic health-related quality of life questionnaire (EuroQol Health Questionnaire, 5 Dimensions; EQ 5-D); to both cases and controls. Hen's egg was the most common offending staple food, affecting 76% of cases. Approximately 7% of cases were allergic to all three staple foods.

    For many voltage-gated ion channels (VGICs), creation of a properly functioning ion channel requires the formation of specific protein-protein interactions between the transmembrane pore-forming subunits and cystoplasmic accessory subunits. Despite the importance of such protein-protein interactions in VGIC function and assembly, their potential as sites for VGIC modulator development has been largely overlooked. Here, we develop meta-xylyl (m-xylyl) stapled peptides that target a prototypic VGIC high affinity protein-protein interaction, the interaction between the voltage-gated calcium channel (Ca V ) pore-forming subunit α-interaction domain (AID) and cytoplasmic β-subunit (Ca V β). We show using circular dichroism spectroscopy, X-ray crystallography, and isothermal titration calorimetry that the m-xylyl staples enhance AID helix formation are structurally compatible with native-like AID:Ca V β interactions and reduce the entropic penalty associated with AID binding to Ca V β. Importantly, electrophysiological studies reveal that stapled AID peptides act as effective inhibitors of the Ca V α 1 :Ca V β interaction that modulate Ca V function in an Ca V β isoform-selective manner. Together, our studies provide a proof-of-concept demonstration of the use of protein-protein interaction inhibitors to control VGIC function and point to strategies for improved AID-based Ca V modulator design.

    Full Text Available Background: This study was conducted to determine the efficacy of staple line coverage using a polyglycolic acid patch and fibrin glue without pleural abrasion to prevent recurrent postoperative pneumothorax. Methods: A retrospective analysis was carried out of 116 operations performed between January 2011 and April 2013. During this period, staple lines were covered with a polyglycolic acid patch and fibrin glue in 58 cases (group A, while 58 cases underwent thoracoscopic bullectomy only (group B. Results: The median follow-up period was 33 months (range, 22 to 55 months. The duration of chest tube drainage was shorter in group A (group A 2.7±1.2 day vs. group B 3.9±2.3 day, p=0.001. Prolonged postoperative air leakage occurred more frequently in group B than in group A (43% vs. 19%, p=0.005. The postoperative recurrence rate of pneumothorax was significantly lower in group A (8.6% than in group B (24.1% (p=0.043. The total cost of treatment during the follow-up period, including the cost for the treatment of postoperative recurrent pneumothorax, was not significantly different between the two groups (p=0.43. Conclusion: Without pleural abrasion, staple line coverage with a medium-sized polyglycolic acid patch and fibrin glue after thoracoscopic bullectomy for primary spontaneous pneumothorax is a useful technique that can reduce the duration of postoperative pleural drainage and the postoperative recurrence rate of pneumothorax.

  10. Automatisms: bridging clinical neurology with criminal law.

    Science.gov (United States)

    Rolnick, Joshua; Parvizi, Josef

    2011-03-01

    The law, like neurology, grapples with the relationship between disease states and behavior. Sometimes, the two disciplines share the same terminology, such as automatism. In law, the "automatism defense" is a claim that action was involuntary or performed while unconscious. Someone charged with a serious crime can acknowledge committing the act and yet may go free if, relying on the expert testimony of clinicians, the court determines that the act of crime was committed in a state of automatism. In this review, we explore the relationship between the use of automatism in the legal and clinical literature. We close by addressing several issues raised by the automatism defense: semantic ambiguity surrounding the term automatism, the presence or absence of consciousness during automatisms, and the methodological obstacles that have hindered the study of cognition during automatisms.

    During the 1970s and 1980s, before synthesizers based on direct sampling of musical sounds became popular, replicating musical instruments using frequency modulation (FM) or wavetable synthesis was one of the “holy grails” of music synthesis. Synthesizers such as the Yamaha DX7 allowed users great flexibility in mixing and matching sounds, but were notoriously difficult to coerce into producing sounds like those of a given instrument. Instrument design wizards practiced the mysteries of FM instrument design.

    Brun, R.; Rademakers, F.

    2001-01-01

    ROOT version 3 (spring 2001) supports automatic class schema evolution. In addition this version also produces files that are self-describing. This is achieved by storing in each file a record with the description of all the persistent classes in the file. Being self-describing guarantees that a file can always be read later, its structure browsed and objects inspected, also when the library with the compiled code of these classes is missing. The schema evolution mechanism supports the frequent case when multiple data sets generated with many different class versions must be analyzed in the same session. ROOT supports the automatic generation of C++ code describing the data objects in a file

    In this paper, we propose a system for automatic design of magazine covers that quantifies a number of concepts from art and aesthetics. Our solution to automatic design of this type of media has been shaped by input from professional designers, magazine art directors and editorial boards, and journalists. Consequently, a number of principles in design and rules in designing magazine covers are delineated. Several techniques are derived and employed in order to quantify and implement these principles and rules in the format of a software framework. At this stage, our framework divides the task of design into three main modules: layout of magazine cover elements, choice of color for masthead and cover lines, and typography of cover lines. Feedback from professional designers on our designs suggests that our results are congruent with their intuition.

    Radioimmunoassay provided dose response curves which showed linearity by the use of logistic transformation (Rodbard). This transformation which was applicable to radioimmunoassay should be useful for the computer processing of insulin and C-peptide assay. In the present studies, standard curves were analysed by testing the fit of analytic functions to radioimmunoassay of insulin and C-peptides. A program for use in combination with the double antibody technique was made by Dr. Kawamata. This approach was evidenced to be useful in order to allow automatic computation of data derived from the double antibody assays of insulin and C-peptides. Automatic corrected calculations of radioimmunoassay data of insulin was found to be satisfactory. (auth.)

    Clinical narratives, such as radiology and pathology reports, are commonly available in electronic form. However, they are also commonly entered and stored as free text. Knowledge of the structure of clinical narratives is necessary for enhancing the productivity of healthcare departments and facilitating research. This study attempts to automatically segment medical reports into semantic sections. Our goal is to develop a robust and scalable medical report segmentation system requiring minimum user input for efficient retrieval and extraction of information from free-text clinical narratives. Hand-crafted rules were used to automatically identify a high-confidence training set. This automatically created training dataset was later used to develop metrics and an algorithm that determines the semantic structure of the medical reports. A word-vector cosine similarity metric combined with several heuristics was used to classify each report sentence into one of several pre-defined semantic sections. This baseline algorithm achieved 79% accuracy. A Support Vector Machine (SVM) classifier trained on additional formatting and contextual features was able to achieve 90% accuracy. Plans for future work include developing a configurable system that could accommodate various medical report formatting and content standards.

    Nuclear power plants are facing strong demands for higher reliability and cost-performance in their control and instrumentation systems. To meet these needs, Hitachi is developing advanced control and instrumentation technology by rationalizing the conventional technology in that field. The rationalization is done through the utilization of reliable digital technology and optical transmission technology, and others, which are now commonly used in computer applications. The goal of the development work is to ensure safe, stable operation of the plant facilities and to secure harmony between man and machine. To alleviate the burdens of the operators, the latest electronic devices are being employed to create an advanced man-machine interface, and to promote automatic operation of the plant based upon the automatic operation of individual systems. In addition, the control and instrumentation system, including the safety system, incorporates more and more digital components in order to further enhance the reliability and maintainability of the plant.

    Parastomal hernia remains a frequent complication following creation of an abdominal stoma. Previous interests have centred around the exploration of methods to repair; however, prophylactic mesh placement has demonstrated its efficacy in reduction of parastomal hernia. The aim of this retrospective analysis was to evaluate the outcomes of Stapled Mesh stomA Reinforcement Technique (SMART) in terms of parastomal hernia occurrence rate and mesh-related complications. All patients operated with an abdominal perineal resection or Hartmann's procedure with SMART from November 2013 to March 2016 were included. Patient demographics, operative details and stoma-related symptoms were collected. Patients were examined clinically by the medical team and also reviewed independently by a specialist stoma care nurse for signs of stoma-related complications. As part of oncological follow-up, CT scans were available for review for evidence of parastomal herniation. 14 patients (mean age 76 years) were included in the analysis. All the SMART cases were successfully completed with no intraoperative or immediate post-operative complications. No cases of mesh-related complications such as infection, immediate stomal prolapse, stenosis, retraction, stomal obstruction, mesh erosion or fistulation were observed. No mesh removal was required. There were two cases of parastomal hernia detected on CT scan. Both cases have remained asymptomatic no intervention was required at this stage. Median follow-up was 24 months. Our medium-term experience has demonstrated the efficacy of SMART in the reduction of parastomal hernia occurrence. With appropriate learning curve, parastomal hernia can be prevented.

    2012-08-01

    Full Text Available Targeted fortification programs for infants and young children are an effective strategy to prevent micronutrient deficiencies in developing countries, but the role of large-scale fortification of staple foods and condiments is less clear. Dietary modeling in children aged 6–60 months was undertaken, based on food consumption patterns described in the 2009 national food consumption survey, using a 24-h recall method. Consumption data showed that the median intake of a child for iron, vitamin A and zinc, as a proportion of the Vietnamese Recommended Dietary Allowance (VRDA, is respectively 16%–48%, 14%–49% and 36%–46%, (depending on the age group. Potential fortification vehicles, such as rice, fish/soy sauces and vegetable oil are consumed daily in significant amounts (median: 170 g/capita/day, 4 g/capita/day and 6 g/capita/day, respectively by over 40% of the children. Vegetable oil fortification could contribute to an additional vitamin A intake of 21%–24% of VRDA recommended nutrient intake, while fortified rice could support the intakes of all the other micronutrients (14%–61% for iron, 4%–11% for zinc and 33%–49% of folate requirements. Other food vehicles, such as wheat flour, which is consumed by 16% of children, could also contribute to efforts to increase micronutrient intakes, although little impact on the prevalence of micronutrient deficiencies can be expected if used alone. The modeling suggests that fortification of vegetable oil, rice and sauces would be an effective strategy to address micronutrient gaps and deficiencies in young children.

    The monitoring of staple and high-value crops is important for maintaining food security. The recent launch of numerous remote sensing satellites has created the ability to monitor vast amounts of crop lands, continuously and in a timely manner. This monitoring provides users with a wealth of information on various crop types over different regions of the world. However, a challenge still remains on how to best quantify and interpret the crop and surface characteristics that are measured by visible, near-infrared, and active and passive microwave radar. Currently, two NASA funded projects are examining the ability to monitor different types of crops in California with different remote sensing platforms. The goal of both projects is to develop a cost-effective monitoring tool for use by vineyard and crop managers. The first project is designed to examine the capability to monitor vineyard water management and soil moisture in Sonoma County using Soil Moisture Active Passive (SMAP), Sentinel-1A and -2, and Landsat-8. The combined mission products create thorough and robust measurements of surface and vineyard characteristics that can potentially improve the ability to monitor vineyard health. Incorporating the Michigan Microwave Canopy Scattering (MIMICS), a radiative transfer model, enables us to better understand surface and vineyard features that influence radar measurements from Sentinel-1A. The second project is a blended approach to analyze corn, rice, and wheat growth using Sentinel-1A products with Decision Support System for Agrotechnology Transfer (DSSAT) and MIMICS models. This project aims to characterize the crop structures that influence Sentinel-1A radar measurements. Preliminary results have revealed the corn, rice, and wheat structures that influence radar measurements during a growing season. The potential of this monitoring tool can be used for maintaining food security. This includes supporting sustainable irrigation practices, identifying crop

    An Automatic drawing system for a report of surface contamination check in a radiation controlled area has been developed. The system can print out the report applied for the format provided by the law from the raw data that is the output from measuring instruments. The task of a worker is only to insert an FD storing the data into a PC and to push a button. The system also yields contamination maps to indicate contamination points clearly. With this system the time to complete the report from the raw data could be decreased from more than two hours to 4 minutes. (author)

    2015-10-01

    Automatic transcription of music is a long-studied research field with many operational systems available commercially. In this paper, a generic transcription system able to host various prior knowledge parameters has been developed, followed by an in-depth investigation of their impact on music transcription. Explicit links between musical knowledge and algorithmic formalism have been made. Musical knowledge covers classes of timbre, musicology, and playing style of an instrument repertoire. An evaluation sound corpus gathering musical pieces played by human performers from three different instrument repertoires, namely, classical piano, steel-string acoustic guitar, and the marovany zither from Madagascar, has been developed. The different components of musical knowledge have been successively incorporated in a complete transcription system, consisting mainly of a Probabilistic Latent Component Analysis algorithm post-processed with a Hidden Markov Model, and their impact on transcription results have been comparatively evaluated.

  20. Unification of automatic target tracking and automatic target recognition

    Schachter, Bruce J.

    2014-06-01

    The subject being addressed is how an automatic target tracker (ATT) and an automatic target recognizer (ATR) can be fused together so tightly and so well that their distinctiveness becomes lost in the merger. This has historically not been the case outside of biology and a few academic papers. The biological model of ATT∪ATR arises from dynamic patterns of activity distributed across many neural circuits and structures (including retina). The information that the brain receives from the eyes is "old news" at the time that it receives it. The eyes and brain forecast a tracked object's future position, rather than relying on received retinal position. Anticipation of the next moment - building up a consistent perception - is accomplished under difficult conditions: motion (eyes, head, body, scene background, target) and processing limitations (neural noise, delays, eye jitter, distractions). Not only does the human vision system surmount these problems, but it has innate mechanisms to exploit motion in support of target detection and classification. Biological vision doesn't normally operate on snapshots. Feature extraction, detection and recognition are spatiotemporal. When vision is viewed as a spatiotemporal process, target detection, recognition, tracking, event detection and activity recognition, do not seem as distinct as they are in current ATT and ATR designs. They appear as similar mechanism taking place at varying time scales. A framework is provided for unifying ATT and ATR.

  2. On automatic machine translation evaluation

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available An important task of developing machine translation (MT is evaluating system performance. Automatic measures are most commonly used for this task, as manual evaluation is time-consuming and costly. However, to perform an objective evaluation is not a trivial task. Automatic measures, such as BLEU, TER, NIST, METEOR etc., have their own weaknesses, while manual evaluations are also problematic since they are always to some extent subjective. In this paper we test the influence of a test set on the results of automatic MT evaluation for the subtitling domain. Translating subtitles is a rather specific task for MT, since subtitles are a sort of summarization of spoken text rather than a direct translation of (written text. Additional problem when translating language pair that does not include English, in our example Slovene-Serbian, is that commonly the translations are done from English to Serbian and from English to Slovenian, and not directly, since most of the TV production is originally filmed in English. All this poses additional challenges to MT and consequently to MT evaluation. Automatic evaluation is based on a reference translation, which is usually taken from an existing parallel corpus and marked as a test set. In our experiments, we compare the evaluation results for the same MT system output using three types of test set. In the first round, the test set are 4000 subtitles from the parallel corpus of subtitles SUMAT. These subtitles are not direct translations from Serbian to Slovene or vice versa, but are based on an English original. In the second round, the test set are 1000 subtitles randomly extracted from the first test set and translated anew, from Serbian to Slovenian, based solely on the Serbian written subtitles. In the third round, the test set are the same 1000 subtitles, however this time the Slovene translations were obtained by manually correcting the Slovene MT outputs so that they are correct translations of the

    2014-11-01

    We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users\\' fairness. The results, which are obtained for single- and multiple-antenna setups, demonstrate the efficiency of the proposed approach in different conditions. For instance, with a maximum of M retransmissions and single transmit/receive antennas, the diversity gain of a user increases from M to (J+1)(M-1)+1 where J is the number of users helping that user.

  6. Motor automaticity in Parkinson’s disease

    Wu, Tao; Hallett, Mark; Chan, Piu

    2017-01-01

    Bradykinesia is the most important feature contributing to motor difficulties in Parkinson’s disease (PD). However, the pathophysiology underlying bradykinesia is not fully understood. One important aspect is that PD patients have difficulty in performing learned motor skills automatically, but this problem has been generally overlooked. Here we review motor automaticity associated motor deficits in PD, such as reduced arm swing, decreased stride length, freezing of gait, micrographia and reduced facial expression. Recent neuroimaging studies have revealed some neural mechanisms underlying impaired motor automaticity in PD, including less efficient neural coding of movement, failure to shift automated motor skills to the sensorimotor striatum, instability of the automatic mode within the striatum, and use of attentional control and/or compensatory efforts to execute movements usually performed automatically in healthy people. PD patients lose previously acquired automatic skills due to their impaired sensorimotor striatum, and have difficulty in acquiring new automatic skills or restoring lost motor skills. More investigations on the pathophysiology of motor automaticity, the effect of L-dopa or surgical treatments on automaticity, and the potential role of using measures of automaticity in early diagnosis of PD would be valuable.

    The requirements and characteristics of radiation measurement instruments vary according to the circumstances under which they are used (field, area, laboratory conditions) and according to their purpose (radiation survey, personal monitoring, use in emergencies, or alpha, beta or gamma counting). In fact, radiation measurement instruments are so varied that only an overview has been presented here. Groups of instruments for these and other conditions or uses are presented in tabular form together with their operational characteristics and requirements. While examples of calibrations, efficiencies and variability of all the listed instruments are not given in this chapter, these parameters are illustrated for the most important types of gamma and beta survey instruments, in some cases with a specific instrument used as an example. Some of the important parameters that need to be considered for laboratory counting of alpha and beta particles are presented. Charts for determination of optimum sample and background counting times, errors and statistics are given

    In 1981 and 1985, two editions of a catalog of non-destructive nuclear measurement instrumentation, and material control and surveillance equipment, were published by Brookhaven National Laboratory (BNL). The last edition of the catalog included one hundred and twenty-five entries covering a wide range of devices developed in the US and abroad. More than ten years have elapsed since the publication of the more recent Catalog. Devices described in it have undergone significant modifications, and new devices have been developed. Therefore, in order to assist specialists in the field of Material Control and Accounting (MC and A), a new catalog has been created. Work on this instrumentation catalog started in 1997 as a cooperative effort of Brookhaven National Laboratory (BNL), operated by Brookhaven Science Associates under contract to the US Department of Energy, and the All-Russian Research Institute of Automatics (VNIIA), subordinate institute of the Atomic Energy Ministry of the Russian Federation, within the collaborative US-Russia Material Protection, Control, and Accounting (MPC and A) Program. Most of the equipment included in the Catalog are non-destructive assay (NDA) measurement devices employed for purposes of accounting, confirmation, and verification of nuclear materials. Other devices also included in the Catalog are employed in the detection and deterrence of unauthorized access to or removal of nuclear materials (material control: containment and surveillance). Equipment found in the Catalog comprises either: (1) complete devices or systems that can be used for MC and A applications; or (2) parts or components of complete systems, such as multi-channel analyzers, detectors, neutron generators, and software.

    Due to the competitive nature of the commercial MRI industry, it is essential for the financial health of a participating company to innovate new coil designs and bring product to market rapidly in response to ever-changing market conditions. However, the technology of MRI coil design is still early in its stage of development and its principles are yet evolving. As a result, it is not always possible to know the relevant electromagnetic effects of a given design since the interaction of coil elements is complex and often counter-intuitive. Even if the effects are known qualitatively, the quantitative results are difficult to obtain. At USA Instruments, Inc., the acquisition of the XFDTDâ electromagnetic simulation tool from REMCOM, Inc., has been helpful in determining the electromagnetic performance characteristics of existing coil designs in the prototype stage before the coils are released for production. In the ideal case, a coil design would be modeled earlier at the conceptual stage, so that only good designs will make it to the prototyping stage and the electromagnetic characteristics better understood very early in the design process and before the testing stage has begun. This paper is a brief overview of using FDTD modeling for MRI coil design at USA Instruments, Inc., and shows some of the highlights of recent FDTD modeling efforts on Birdcage coils, a staple of the MRI coil design portfolio.

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

    Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program.

    Full Text Available Abstract Here we report the method of anastomosis based on double stapling technique (hereinafter, DST using a trans-oral anvil delivery system (EEATM OrVilTM for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, laparoscopic total gastrectomy employed Roux-en-Y reconstruction, laparoscopic proximal gastrectomy employed double tract reconstruction, and end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. We used EEATM OrVilTM as a device that permitted mechanical purse-string suture similarly to conventional EEA, and endo-Surgitie. After the gastric lymph node dissection, the esophagus was cut off using an automated stapler. EEATM OrVilTM was orally and slowly inserted from the valve tip, and a small hole was created at the tip of the obliquely cut-off stump with scissors to let the valve tip pass through. Yarn was cut to disconnect the anvil from a tube and the anvil head was retained in the esophagus. The end-Surgitie was inserted at the right subcostal margin, and after the looped-shaped thread was wrapped around the esophageal stump opening, assisting Maryland forceps inserted at the left subcostal and left abdomen were used to grasp the left and right esophageal stump. The surgeon inserted anvil grasping forceps into the right abdomen, and after grasping the esophagus with the forceps, tightened the end Surgitie, thereby completing the purse-string suture on the esophageal stump. The main unit of the automated stapler was inserted from the cut-off stump of the lifted jejunum, and a trocar was made to pass through. To prevent dropout of the small intestines from the automated stapler, the automated stapler and the lifted jejunum were fastened with silk thread, the abdomen was again inflated, and the lifted jejunum was led into the abdominal cavity. When it was confirmed that the automated stapler and center rod

  1. Assessment of MRI issues at 3-Tesla for metallic surgical implants: findings applied to 61 additional skin closure staples and vessel ligation clips

    2012-01-01

    Purpose Metallic skin closure staples and vessel ligation clips should be tested at 3-Tesla to characterize MRI issues in order to ensure patient safety. Therefore, metallic surgical implants were assessed at 3-Tesla for magnetic field interactions, MRI-related heating, and artifacts. Methods A skin closure staple (Visistat Skin Stapler, staple, Polytetrafluoroethylene, PTFE, coated 316L/316LVM stainless steel; Teleflex Medical, Durham, NC) and a vessel ligation clip (Hemoclip Traditional, stainless steel; Teleflex Medical, Durham, NC) that represented the largest metallic sizes made from materials with the highest magnetic susceptibilities (i.e., based on material information) among 61 other surgical implants (52 metallic implants, 9 nonmetallic implants) underwent evaluation for magnetic field interactions, MRI-related heating, and artifacts using standardized techniques. MRI-related heating was assessed by placing each implant in a gelled-saline-filled phantom with MRI performed using a transmit/receive RF body coil at an MR system reported, whole body averaged SAR of 2.9-W/kg for 15-min. Artifacts were characterized using T1-weighted, SE and GRE pulse sequences. Results Each surgical implant showed minor magnetic field interactions (20- and 27-degrees, which is acceptable from a safety consideration). Heating was not substantial (highest temperature change, ≤ 1.6°C). Artifacts may create issues if the area of interest is in the same area or close to the respective surgical implant. Conclusions The results demonstrated that it would be acceptable for patients with these metallic surgical implants to undergo MRI at 3-Tesla or less. Because of the materials and dimensions of the surgical implants that underwent testing, these findings pertain to 61 additional similar implants. PMID:22230200

    Stapled haemorrhoidectomy has been performed with different techniques and staplers. We review our initial experience with the new DST EEA 33 stapler and neu@ anoscope. A review of all patients who underwent stapled haemorrhoidectomy using the DST EEA 33 over a 14-month period was conducted. Short-term outcomes of bleeding, pain and retention of urine requiring admission or strictures requiring surgical intervention were studied. There were 1,118 patients operated from August 2007 to October 2008. The median age was 46-year-old (20-82 years) and 51% were females. The median operating time was 15 min (range 5-45 min), and median follow-up was 7 months (range 3-16 months). There were 26 patients (2.3%) who were admitted for inability to pass urine and 20 required catheterisation. Fifty-two patients (4.6%) were admitted for post-operative bleeding. In 32 cases the bleeding stopped spontaneously, while 19 patients required adrenaline injection and packing for hemostasis. Only one patient required surgical hemostasis. Thirty-three patients (2.9%) were admitted for post-operative pain and stayed for a median of 1 day (range 1-4 days). There were 14 patients (1.2%) who developed anorectal strictures requiring surgical intervention. All underwent anoplasty at a median of 3 months post-operatively (range 2-5 months), with good result. There were no recurrent haemorrhoids during follow-up. Stapled haemorrhoidectomy using the DST EEA 33 stapler is safe. The neu@ anoscope provides good visibility and handling, and is a useful tool in this procedure.

    A remotely controlled automatic special welding machine for piping was developed. This machine is utilized for long distance pipe lines, chemical plants, thermal power generating plants and nuclear power plants effectively from the viewpoint of good quality control, reduction of labor and good controllability. The function of this welding machine is to inspect the shape and dimensions of edge preparation before welding work by the sense of touch, to detect the temperature of melt pool, inspect the bead form by the sense of touch, and check the welding state by ITV during welding work, and to grind the bead surface and inspect the weld metal by ultrasonic test automatically after welding work. The construction of this welding system, the main specification of the apparatus, the welding procedure in detail, the electrical source of this welding machine, the cooling system, the structure and handling of guide ring, the central control system and the operating characteristics are explained. The working procedure and the effect by using this welding machine, and the application to nuclear power plants and the other industrial field are outlined. The HIDIC 08 is used as the controlling computer. This welding machine is useful for welding SUS piping as well as carbon steel piping. (Nakai, Y.)

  4. SRV-automatic handling device

    1987-01-01

    Automatic handling device for the steam relief valves (SRV's) is developed in order to achieve a decrease in exposure of workers, increase in availability factor, improvement in reliability, improvement in safety of operation, and labor saving. A survey is made during a periodical inspection to examine the actual SVR handling operation. An SRV automatic handling device consists of four components: conveyor, armed conveyor, lifting machine, and control/monitoring system. The conveyor is so designed that the existing I-rail installed in the containment vessel can be used without any modification. This is employed for conveying an SRV along the rail. The armed conveyor, designed for a box rail, is used for an SRV installed away from the rail. By using the lifting machine, an SRV installed away from the I-rail is brought to a spot just below the rail so that the SRV can be transferred by the conveyor. The control/monitoring system consists of a control computer, operation panel, TV monitor and annunciator. The SRV handling device is operated by remote control from a control room. A trial equipment is constructed and performance/function testing is carried out using actual SRV's. As a result, is it shown that the SRV handling device requires only two operators to serve satisfactorily. The required time for removal and replacement of one SRV is about 10 minutes. (Nogami, K.)

  5. Automatic scanning of emulsion films

    2003-01-01

    The use of nuclear emulsions in recent large neutrino experiments is mostly due to the significant results in the developments of this detection technique. In the emulsion films, trajectories of through-going particles are permanently recorded: thus, the emulsion target can be considered not only as a tracking but also as a storing device. If the data readout is performed by automatic scanning systems interfaced to an acquisition computer equipped with a fast frame grabber, nuclear emulsions can be used as very large target detector and quickly analyzed in particle physics experiments. Techniques for automatic scanning of nuclear emulsions have been developed in the early past. The effort was initiated by Niwa at Nagoya (Japan) in the late 70s. The first large-scale application was the CHORUS experiment; then emulsions have been used to search for T neutrinos in a high track density environment like DONUT. In order to measure with high accuracy and high speed, very strict constraints must be satisfied in terms of mechanical precisions, camera speed, image processing power. Recent improvements in this technique are briefly reported

  6. Automatic generation of tourist brochures

    Birsak, Michael

    2014-05-01

    We present a novel framework for the automatic generation of tourist brochures that include routing instructions and additional information presented in the form of so-called detail lenses. The first contribution of this paper is the automatic creation of layouts for the brochures. Our approach is based on the minimization of an energy function that combines multiple goals: positioning of the lenses as close as possible to the corresponding region shown in an overview map, keeping the number of lenses low, and an efficient numbering of the lenses. The second contribution is a route-aware simplification of the graph of streets used for traveling between the points of interest (POIs). This is done by reducing the graph consisting of all shortest paths through the minimization of an energy function. The output is a subset of street segments that enable traveling between all the POIs without considerable detours, while at the same time guaranteeing a clutter-free visualization. © 2014 The Author(s) Computer Graphics Forum © 2014 The Eurographics Association and John Wiley & Sons Ltd.

    Life-cycle analysis of staple food (rice, flour and corn-based fodder) production and assessments of the associated greenhouse gas (GHG) and reactive nitrogen (Nr) releases, from environmental and economic perspectives, help to develop effective mitigation options. However, such evaluations have rarely been executed in China. We evaluated the GHG and Nr releases per kilogram of staple food production (carbon and Nr footprints) and per unit of net economic benefit (CO{sub 2-NEB} and Nr{sub -NEB}), and explored their mitigation potential. Carbon footprints of food production in China were obviously higher than those in some developed countries. There was a high spatial variation in the footprints, primarily attributable to differences in synthetic N use (or CH{sub 4} emissions) per unit of food production. Provincial carbon footprints had a significant linear relationship with Nr footprints, attributed to large contribution of N fertilizer use to both GHG and Nr releases. Synthetic N fertilizer applications and CH{sub 4} emissions dominated the carbon footprints, while NH{sub 3} volatilization and N leaching were the main contributors to the Nr footprints. About 564 (95% uncertainty range: 404–701) Tg CO{sub 2} eq GHG and 10 (7.4–12.4) Tg Nr-N were released every year during 2001–2010 from staple food production. This caused the total damage costs of 325 (70–555) billion ¥, equivalent to nearly 1.44% of the Gross Domestic Product of China. Moreover, the combined damage costs and economic input costs, accounted for 66%-80% of the gross economic benefit generated from food production. A reduction of 92.7 Tg CO{sub 2} eq yr{sup −1} and 2.2 Tg Nr-N yr{sup −1} could be achieved by reducing synthetic N inputs by 20%, increasing grain yields by 5% and implementing off-season application of straw and mid-season drainage practices for rice cultivation. In order to realize these scenarios, an ecological compensation scheme should be established to incentivize

  10. The design of an automatically-tuned beamline

    1994-01-01

    A new 30 m beamline (BL1C) is being assembled to connect the new High Intensity Polarized Ion Source (HIPIOS) to the IUCF cyclotrons. This line is being instrumented for complete automatic optimization of all transverse and longitudinal ion optical elements by providing a unique feedback signal for each controllable device. Transversely, steerers and 4-quadrant electrostatic pickups are located approximately 90 degree apart in betatron phase advance along the beamline. Each pickup is instrumented with a single-board, 4-layer op-amp circuit (BPM system) which measures the beam intensity, horizontal (H) and vertical (V) position, and H and V 10 Hz position modulation. The transverse beam ellipse parameters are first automatically determined at the entrance to the beamline by measuring the beam size using a wire scanner as a function of the strength of a quadrupole. The computer then programs the amplitude and phase of four 10 Hz modulators which vary the current in 4 steerers to move the beam centroid around this (reduced area) ellipse in 4-dimensional phase space. The BPM system then outputs voltages proportional to the beam intensity, centroid location, and envelope. Computer algorithms will then set the steerers and quadrupoles to correct the beam position, dispersion, and envelope. Longitudinally, hardware feedback loops, with a bandwidth adjustable from 10 Hz to 30 kHz, will phase-lock the beam to the two bunching systems; another hardware system will automatically vary the buncher amplitudes to compensate for the significant and varying space charge defocusing as the beam current fluctuates. The bunchers' quiescent phases and amplitudes will be optimized using software ''synchronous detectors.''

    1998-01-01

    Conforming to the latest issues of the Nuclear Regulatory Commission Regulatory Guide, a novel hardware and software solution for seismic instrumentation is presented. Both instrumentation and PC-based data evaluation software for post-earthquake actions are type-tested and approved by the German TUeV. Reference installations replacing obsolete analog instrumentation were successfully completed and are presented. The instrumentation consists of highly linear, solid-state capacitive accelerometers as well as digital recorders storing the signals from the sensors in situ. These recorders are linked in a star-topology network to a central unit that permanently communicates with them via fiber-optic cable or current-loop links. The central unit is responsible for alerting and synchronizes all recorders which otherwise act autonomously. Data evaluation is handled by a PC-based software package. It includes automatic data evaluation after earthquakes (batch mode), interactive data evaluation software for detailed data analysis, and software tools for remote operation, maintenance and data storage.

    Antares is a 24-beam-line CO 2 laser system for controlled fusion research, under construction at Los Alamos Scientific Laboratory (LASL). Rapid automatic alignment of this system is required prior to each experiment shot. The alignment requirements, operational constraints, and a developed prototype system are discussed. A visible-wavelength alignment technique is employed that uses a telescope/TV system to view point light sources appropriately located down the beamline. Auto-alignment is accomplished by means of a video centroid tracker, which determines the off-axis error of the point sources. The error is nulled by computer-driven, movable mirrors in a closed-loop system. The light sources are fiber-optic terminations located at key points in the optics path, primarily at the center of large copper mirrors, and remotely illuminated to reduce heating effects

    In BWR nuclear power stations the Traversing Incore Probe (TIP) system is one of the most important components in reactor monitoring and control. In previous TIP systems, however, operators have suffered from the complexity of operation and long operation time required. The system presented in this paper realizes the automatic operation of the TIP system by monitoring and driving it with a process computer. This system significantly reduces the burden on customer operators and improves plant efficiency by simplifying the operating procedure, augmenting the accuracy of the measured data, and shortening operating time. The process computer is one of the PODIA (Plant Operation by Displayed Information Automation) systems. This computer transfers control signals to the TIP control panel, which in turn drives equipment by microprocessor control. The process computer contains such components as the CRT/KB unit, the printer plotter, the hard copier, and the message typers required for efficient man-machine communications. Its operation and interface properties are described

    2014-05-01

    Climate change has already a large impact on the availability of water resources. Many regions in South-East Asia are assumed to receive less water in the future, dramatically impacting the production of the most important staple food: rice (Oryza sativa L.). Rice is the primary food source for nearly half of the World's population, and is the only cereal that can grow under wetland conditions. Especially anaerobic (flooded) rice fields require high amounts of water but also have higher yields than aerobic produced rice. In the past different methods were developed to reduce the water use in rice paddies, like alternative wetting and drying or the use of mixed cropping systems with aerobic (non-flooded) rice and alternative crops such as maize. A more detailed understanding of water and nutrient cycling in rice-based cropping systems is needed to reduce water use, and requires the investigation of hydrological and biochemical processes as well as transport dynamics at the field scale. New developments in analytical devices permit monitoring parameters at high temporal resolutions and at acceptable costs without much necessary maintenance or analysis over longer periods. Here we present a new type of automatic sampling set-up that facilitates in situ analysis of hydrometric information, stable water isotopes and nitrate concentrations in spatially differentiated agricultural fields. The system facilitates concurrent monitoring of a large number of water and nutrient fluxes (ground, surface, irrigation and rain water) in irrigated agriculture. For this purpose we couple an automatic sampling system with a Wavelength-Scanned Cavity Ring Down Spectrometry System (WS-CRDS) for stable water isotope analysis (δ2H and δ18O), a reagentless hyperspectral UV photometer for monitoring nitrate content and various water level sensors for hydrometric information. The whole system is maintained with special developed software for remote control of the system via internet. We

    Purpose: To develop a set of atlases for automatic contouring of cardiac structures to determine heart radiation dose and the associated toxicity. Methods: Six thoracic cancer patients with both contrast and non-contrast CT images were acquired for this study. Eight radiation oncologists manually and independently delineated cardiac contours on the non-contrast CT by referring to the fused contrast CT and following the RTOG 1106 atlas contouring guideline. Fifteen regions of interest (ROIs) were delineated, including heart, four chambers, four coronary arteries, pulmonary artery and vein, inferior and superior vena cava, and ascending and descending aorta. Individual expert contours were fused using the simultaneous truth and performance level estimation (STAPLE) algorithm for each ROI and each patient. The fused contours became atlases for an in-house multi-atlas segmentation. Using leave-one-out test, we generated auto-segmented contours for each ROI and each patient. The auto-segmented contours were compared with the fused contours using the Dice similarity coefficient (DSC) and the mean surface distance (MSD). Results: Inter-observer variability was not obvious for heart, chambers, and aorta but was large for other structures that were not clearly distinguishable on CT image. The average DSC between individual expert contours and the fused contours were less than 50% for coronary arteries and pulmonary vein, and the average MSD were greater than 4.0 mm. The largest MSD of expert contours deviating from the fused contours was 2.5 cm. The mean DSC and MSD of auto-segmented contours were within one standard deviation of expert contouring variability except the right coronary artery. The coronary arteries, vena cava, and pulmonary vein had DSC<70% and MSD>3.0 mm. Conclusion: A set of cardiac atlases was created for cardiac automatic contouring, the accuracy of which was comparable to the variability in expert contouring. However, substantial modification may need

    Full Text Available - Automatic system has brought many revolutions in the existing technologies. One among the technologies, which has greater developments, is the solar powered automatic shrimp feeding system. For instance, the solar power which is a renewable energy can be an alternative solution to energy crisis and basically reducing man power by using it in an automatic manner. The researchers believe an automatic shrimp feeding system may help solve problems on manual feeding operations. The project study aimed to design and develop a solar powered automatic shrimp feeding system. It specifically sought to prepare the design specifications of the project, to determine the methods of fabrication and assembly, and to test the response time of the automatic shrimp feeding system. The researchers designed and developed an automatic system which utilizes a 10 hour timer to be set in intervals preferred by the user and will undergo a continuous process. The magnetic contactor acts as a switch connected to the 10 hour timer which controls the activation or termination of electrical loads and powered by means of a solar panel outputting electrical power, and a rechargeable battery in electrical communication with the solar panel for storing the power. By undergoing through series of testing, the components of the modified system were proven functional and were operating within the desired output. It was recommended that the timer to be used should be tested to avoid malfunction and achieve the fully automatic system and that the system may be improved to handle changes in scope of the project.

    We have constructed a second generation instrument for performing automated thin layer chromatography (TLC), The TLC instrument Consists of four dedicated stations for (1) plate dispensing, (2) sample application, (3) plate development, and (4) densitometry. A robot is used to move TLC plates among stations. The TLC instrument functions either as a stand-alone unit or as one analytical module in a robotic workstation for synthetic chemistry. An integrated hardware and software architecture enables automatic TLC analysis of samples produced concurrently from synthetic reactions in progress on the workstation. The combination of fixed automation and robotics gives a throughput of 12 TLC samples per hour. From these results a blueprint has emerged for an advanced automated TLC instrument with far greater throughput and analytical capabilities

    1991-01-01

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

  11. Future of radiological instrumentation

    International Nuclear Information System (INIS)

    Lucas, A.C.

    1988-01-01

    Future trends in the development of radiation protection instrumentation can be expected to be closely related to current trends in political and social activity that drive legislation, rule-making, and standard practice, with assistance provided by trends in material and electronic technology. Wide-range performance will be emphasized to arm the daily worker with instruments that routinely log background rates and, at the same time, are prepared to measure accident rates. Separate and simultaneous accumulation of data from several sensors to ensure complete coverage of the radiation types will be common. Mathematical manipulation of data will provide for summary data logging and, in some cases, solutions to integral equations to provide corrections to experimental data. Instruments will become more reliable by way of self-checking and correction. Miniaturization and large-scale integration of measuring instruments will provide some instrumentation for the people at large. To be effective, the instruments will necessarily cover a wide range and be very reliable. The net result of these several trends will provide for a widespread understanding of radiation protection and an implementation of as low as reasonably achievable among large segments of the population

  12. [The instrument for thermography].

    Science.gov (United States)

    Hamaguchi, Shinsuke

    2014-07-01

    Thermography is an imaging method using the instrument to detect infrared rays emitted from the body surface, and to plot them as a distribution diagram of the temperature information. Therefore, a thermographic instrument can be assumed to measure the skin temperature of the diseased region. Such an instrument is a useful device for noninvasive and objective assessment of various diseases. Examination using a thermographic instrument can assess the autonomic dysfunction by measuring the skin blood flow involved with the sympathetic innervation. Thermography is useful in assisting the determination of the therapeutic effect. However, autonomic dysfunction should be confirmed correctly with the assessment of thermatome that shows abnormal thermal distribution in the region of the disease. Thermography should make noticeable the difference between the body temperature of abnormal and normal sites, and show the alteration of temperature. Monitoring using thermography is useful to determine the effect of sympathetic nerve block. If a thermographic instrument is used, it is important that examiners should understand the function of the instrument, as well as its advantages and disadvantages.

  13. Problems with radiological surveillance instrumentation

    Swinth, K.L.; Tanner, J.E.; Fleming, D.M.

    1984-09-01

    Many radiological surveillance instruments are in use at DOE facilities throughout the country. These instruments are an essential part of all health physics programs, and poor instrument performance can increase program costs or compromise program effectiveness. Generic data from simple tests on newly purchased instruments shows that many instruments will not meet requirements due to manufacturing defects. In other cases, lack of consideration of instrument use has resulted in poor acceptance of instruments and poor reliability. The performance of instruments is highly variable for electronic and mechanical performance, radiation response, susceptibility to interferences and response to environmental factors. Poor instrument performance in these areas can lead to errors or poor accuracy in measurements

    Kelly, J. R.; Niessen, F. R.; Garren, J. F., Jr.

    1973-01-01

    The operation of VTOL aircraft in the city-center environment will require complex landing-approach trajectories that insure adequate clearance from other traffic and obstructions and provide the most direct routing for efficient operations. As part of a larger program to develop the necessary technology base, a flight investigation was undertaken to study the problems associated with manual and automatic control of steep, decelerating instrument approaches and landings. The study employed a three-cue flight director driven by control laws developed and refined during manual-control studies and subsequently applied to the automatic approach problem. The validity of this approach was demonstrated by performing the first automatic approach and landings to a predetermined spot ever accomplished with a helicopter. The manual-control studies resulted in the development of a constant-attitude deceleration profile and a low-noise navigation system.

  15. Automatic setting of the distance between sample and detector in gamma-ray spectroscopy

    International Nuclear Information System (INIS)

    Andeweg, A.H.

    1980-01-01

    An apparatus has been developed that automatically sets the distance from the sample to the detector according to the radioactivity of the sample. The distance-setting unit works in conjuction with an automatic sample changer, and is interconnected with other components so that the counting head automatically moves to the optimum distance for the analysis of a particular sample. The distance, which is indicated digitally in increments of 0,01 mm, can be set between 18 and 995 mm at count rates that can be preset between 1000 and 10 000 counts per second. On being tested, the instrument performed well within the desired range and accuracy. Under routine conditions, the spectra were much more accurate than before, especially when samples of different radioactivity were counted

  16. Optical Methods For Automatic Rating Of Engine Test Components

    Science.gov (United States)

    Pritchard, James R.; Moss, Brian C.

    1989-03-01

    In recent years, increasing commercial and legislative pressure on automotive engine manufacturers, including increased oil drain intervals, cleaner exhaust emissions and high specific power outputs, have led to increasing demands on lubricating oil performance. Lubricant performance is defined by bench engine tests run under closely controlled conditions. After test, engines are dismantled and the parts rated for wear and accumulation of deposit. This rating must be consistently carried out in laboratories throughout the world in order to ensure lubricant quality meeting the specified standards. To this end, rating technicians evaluate components, following closely defined procedures. This process is time consuming, inaccurate and subject to drift, requiring regular recalibration of raters by means of international rating workshops. This paper describes two instruments for automatic rating of engine parts. The first uses a laser to determine the degree of polishing of the engine cylinder bore, caused by the reciprocating action of piston. This instrument has been developed to prototype stage by the NDT Centre at Harwell under contract to Exxon Chemical, and is planned for production within the next twelve months. The second instrument uses red and green filtered light to determine the type, quality and position of deposit formed on the piston surfaces. The latter device has undergone feasibility study, but no prototype exists.

  17. Automatic locking orthotic knee device

    Science.gov (United States)

    Weddendorf, Bruce C. (Inventor)

    1993-01-01

    An articulated tang in clevis joint for incorporation in newly manufactured conventional strap-on orthotic knee devices or for replacing such joints in conventional strap-on orthotic knee devices is discussed. The instant tang in clevis joint allows the user the freedom to extend and bend the knee normally when no load (weight) is applied to the knee and to automatically lock the knee when the user transfers weight to the knee, thus preventing a damaged knee from bending uncontrollably when weight is applied to the knee. The tang in clevis joint of the present invention includes first and second clevis plates, a tang assembly and a spacer plate secured between the clevis plates. Each clevis plate includes a bevelled serrated upper section. A bevelled shoe is secured to the tank in close proximity to the bevelled serrated upper section of the clevis plates. A coiled spring mounted within an oblong bore of the tang normally urges the shoes secured to the tang out of engagement with the serrated upper section of each clevic plate to allow rotation of the tang relative to the clevis plate. When weight is applied to the joint, the load compresses the coiled spring, the serrations on each clevis plate dig into the bevelled shoes secured to the tang to prevent relative movement between the tang and clevis plates. A shoulder is provided on the tang and the spacer plate to prevent overextension of the joint.

  18. Pattern-Driven Automatic Parallelization

    Directory of Open Access Journals (Sweden)

    Christoph W. Kessler

    1996-01-01

    Full Text Available This article describes a knowledge-based system for automatic parallelization of a wide class of sequential numerical codes operating on vectors and dense matrices, and for execution on distributed memory message-passing multiprocessors. Its main feature is a fast and powerful pattern recognition tool that locally identifies frequently occurring computations and programming concepts in the source code. This tool also works for dusty deck codes that have been "encrypted" by former machine-specific code transformations. Successful pattern recognition guides sophisticated code transformations including local algorithm replacement such that the parallelized code need not emerge from the sequential program structure by just parallelizing the loops. It allows access to an expert's knowledge on useful parallel algorithms, available machine-specific library routines, and powerful program transformations. The partially restored program semantics also supports local array alignment, distribution, and redistribution, and allows for faster and more exact prediction of the performance of the parallelized target code than is usually possible.

  19. Automatic Transmission Of Liquid Nitrogen

    2015-08-01

    Full Text Available Liquid Nitrogen is one of the major substance used as a chiller in industry such as Ice cream factory Milk Diary Storage of blood sample Blood Bank etc. It helps to maintain the required product at a lower temperature for preservation purpose. We cannot fully utilise the LN2 so practically if we are using 3.75 litre LN2 for a single day then around 12 of LN2 450 ml is wasted due to vaporisation. A pressure relief valve is provided to create a pressure difference. If there is no pressure difference between the cylinder carrying LN2 and its surrounding it will results in damage of container as well as wastage of LN2.Transmission of LN2 from TA55 to BA3 is carried manually .So care must be taken for the transmission of LN2 in order to avoid its wastage. With the help of this project concept the transmission of LN2 will be carried automatically so as to reduce the wastage of LN2 in case of manual operation.

  20. Automatic segmentation of the colon

    Virtual colonoscopy is a minimally invasive technique that enables detection of colorectal polyps and cancer. Normally, a patient's bowel is prepared with colonic lavage and gas insufflation prior to computed tomography (CT) scanning. An important step for 3D analysis of the image volume is segmentation of the colon. The high-contrast gas/tissue interface that exists in the colon lumen makes segmentation of the majority of the colon relatively easy; however, two factors inhibit automatic segmentation of the entire colon. First, the colon is not the only gas-filled organ in the data volume: lungs, small bowel, and stomach also meet this criteria. User-defined seed points placed in the colon lumen have previously been required to spatially isolate only the colon. Second, portions of the colon lumen may be obstructed by peristalsis, large masses, and/or residual feces. These complicating factors require increased user interaction during the segmentation process to isolate additional colon segments. To automate the segmentation of the colon, we have developed a method to locate seed points and segment the gas-filled lumen with no user supervision. We have also developed an automated approach to improve lumen segmentation by digitally removing residual contrast-enhanced fluid resulting from a new bowel preparation that liquefies and opacifies any residual feces.

    Historically, the US Army has recognized the advantages of panoramic imagers with high image resolution: increased area coverage with fewer cameras, instantaneous full horizon detection, location and tracking of multiple targets simultaneously, extended range, and others. The novel ViperViewTM high-resolution panoramic thermal imager is the heart of the Automatic Panoramic Thermal Integrated Sensor (APTIS), being jointly developed by Applied Science Innovative, Inc. (ASI) and the Armament Research, Development and Engineering Center (ARDEC) in support of the Future Combat Systems (FCS) and the Intelligent Munitions Systems (IMS). The APTIS is anticipated to operate as an intelligent node in a wireless network of multifunctional nodes that work together to improve situational awareness (SA) in many defense and offensive operations, as well as serve as a sensor node in tactical Intelligence Surveillance Reconnaissance (ISR). The ViperView is as an aberration-corrected omnidirectional imager with small optics designed to match the resolution of a 640x480 pixels IR camera with improved image quality for longer range target detection, classification, and tracking. The same approach is applicable to panoramic cameras working in the visible spectral range. Other components of the ATPIS sensor suite include ancillary sensors, advanced power management, and wakeup capability. This paper describes the development status of the APTIS system.

    2014-10-01

    The automatic segmentation of psoriatic lesions is widely researched these years. It is an important step in Computer-aid methods of calculating PASI for estimation of lesions. Currently those algorithms can only handle single erythema or only deal with scaling segmentation. In practice, scaling and erythema are often mixed together. In order to get the segmentation of lesions area - this paper proposes an algorithm based on Random forests with color and texture features. The algorithm has three steps. The first step, the polarized light is applied based on the skin's Tyndall-effect in the imaging to eliminate the reflection and Lab color space are used for fitting the human perception. The second step, sliding window and its sub windows are used to get textural feature and color feature. In this step, a feature of image roughness has been defined, so that scaling can be easily separated from normal skin. In the end, Random forests will be used to ensure the generalization ability of the algorithm. This algorithm can give reliable segmentation results even the image has different lighting conditions, skin types. In the data set offered by Union Hospital, more than 90% images can be segmented accurately.

    Most behaviors unfold in time and include a sequence of submovements or cognitive activities. In addition, most behaviors are automatic and repeated daily throughout life. Yet, relatively little is known about the neurobiology of automatic sequence production. Past research suggests a gradual transfer from the associative striatum to the sensorimotor striatum, but a number of more recent studies challenge this role of the BG in automatic sequence production. In this article, we propose a new neurocomputational model of automatic sequence production in which the main role of the BG is to train cortical-cortical connections within the premotor areas that are responsible for automatic sequence production. The new model is used to simulate four different data sets from human and nonhuman animals, including (1) behavioral data (e.g., RTs), (2) electrophysiology data (e.g., single-neuron recordings), (3) macrostructure data (e.g., TMS), and (4) neurological circuit data (e.g., inactivation studies). We conclude with a comparison of the new model with existing models of automatic sequence production and discuss a possible new role for the BG in automaticity and its implication for Parkinson's disease.

    Reactor Protection System (RPS) is important for Reactor Instrumentation and Control System. The RPS comprises all redundant electrical devices and circuitry involved in the generation of those initiating signals associated to the trip protective function. The instrumentation system for the RPS provides automatic protection signals against unsafe and improper reactor operation. The physical separation is provided for all of the redundant instrumentation systems to preserve redundancy. The safety protection systems using circuits composed of analog instruments and relays with relay contacts is difficult to realize from various reasons. Therefore, an application of digital technology can be said a logical conclusion also in the light of its functional superiority. (author)

  5. Reactor instrumentation and control

    International Nuclear Information System (INIS)

    Wach, D.; Beraha, D.

    1980-01-01

    The methods for measuring radiation are shortly reviewed. The instrumentation for neutron flux measurement is classified into out-of-core and in-core instrumentation. The out-of-core instrumentation monitors the operational range from the subcritical reactor to full power. This large range is covered by several measurement channels which derive their signals from counter tubes and ionization chambers. The in-core instrumentation provides more detailed information on the power distribution in the core. The self-powered neutron detectors and the aeroball system in PWR reactors are discussed. Temperature and pressure measurement devices are briefly discussed. The different methods for leak detection are described. In concluding the plant instrumentation part some new monitoring systems and analysis methods are presented: early failure detection methods by noise analysis, acoustic monitoring and vibration monitoring. The presentation of the control starts from an qualitative assessment of the reactor dynamics. The chosen control strategy leads to the definition of the part-load diagram, which provides the set-points for the different control systems. The tasks and the functions of these control systems are described. In additiion to the control, a number of limiting systems is employed to keep the reactor in a safe operating region. Finally, an outlook is given on future developments in control, concerning mainly the increased application of process computers. (orig./RW)

  6. Instrumental analysis, second edition

    International Nuclear Information System (INIS)

    Christian, G.D.; O'Reilly, J.E.

    1988-01-01

    The second edition of Instrumental Analysis is a survey of the major instrument-based methods of chemical analysis. It appears to be aimed at undergraduates but would be equally useful in a graduate course. The volume explores all of the classical quantitative methods and contains sections on techniques that usually are not included in a semester course in instrumentation (such as electron spectroscopy and the kinetic methods). Adequate coverage of all of the methods contained in this book would require several semesters of focused study. The 25 chapters were written by different authors, yet the style throughout the book is more uniform than in the earlier edition. With the exception of a two-chapter course in analog and digital circuits, the book purports to de-emphasize instrumentation, focusing more on the theory behind the methods and the application of the methods to analytical problems. However, a detailed analysis of the instruments used in each method is by no means absent. The book has the favor of a user's guide to analysis

    In the last few years a much greater emphasis has been placed upon understanding, controlling and monitoring the environmental effects of the advancing technologies. This has resulted in rapid advances in techniques for environmental monitoring. To aid the concerned scientist in keeping abreast of these developments, the Lawrence Berkeley Laboratory publishes a collection of volumes entitled Instrumentation for Environmental Monitoring. Separated into four volumes covering four media, AIR, WATER, RADIATION, and BIOMEDICAL, they provide a source book for three types of material: (1) Monitoring Rationale. They describe the characteristics, forms, and effects of a wide variety of pollutants and the means of controlling them. Federal regulations are explained and summarized. (2) Analytical Techniques. Methods of determining specific pollutants are described with special emphasis on the principles that form the basis of instrumental methods. (3) Commercial Instrumentation. The features of most commercially available instrumentation used for the determination and monitoring of each pollutant are presented in a manner that facilitates instrumental comparisons. Examples of the types of material in the volumes and the use of the volumes are presented

    2017-01-01

    With the creation of numerous automatic detection algorithms, a number of different catalogs of coronal mass ejections (CMEs) spanning the entirety of the Solar and Heliospheric Observatory ( SOHO ) Large Angle Spectrometric Coronagraph (LASCO) mission have been created. Some of these catalogs have been further expanded for use on data from the Solar Terrestrial Earth Observatory ( STEREO ) Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) as well. We compare the results from different automatic detection catalogs (Solar Eruption Event Detection System (SEEDS), Computer Aided CME Tracking (CACTus), and Coronal Image Processing (CORIMP)) to ensure the consistency of detections in each. Over the entire span of the LASCO catalogs, the automatic catalogs are well correlated with one another, to a level greater than 0.88. Focusing on just periods of higher activity, these correlations remain above 0.7. We establish the difficulty in comparing detections over the course of LASCO observations due to the change in the instrument image cadence in 2010. Without adjusting catalogs for the cadence, CME detection rates show a large spike in cycle 24, despite a notable drop in other indices of solar activity. The output from SEEDS, using a consistent image cadence, shows that the CME rate has not significantly changed relative to sunspot number in cycle 24. These data, and mass calculations from CORIMP, lead us to conclude that any apparent increase in CME rate is a result of the change in cadence. We study detection characteristics of CMEs, discussing potential physical changes in events between cycles 23 and 24. We establish that, for detected CMEs, physical parameters can also be sensitive to the cadence.

    The increase in traffic accidents is becoming a serious social problem with the recent rapid traffic increase. In many cases, the driver"s carelessness is the primary factor of traffic accidents, and the driver assistance system is demanded for supporting driver"s safety. In this research, we propose the new method of automatic detection and recognition of road signs by image processing. The purpose of this research is to prevent accidents caused by driver"s carelessness, and call attention to a driver when the driver violates traffic a regulation. In this research, high accuracy and the efficient sign detecting method are realized by removing unnecessary information except for a road sign from an image, and detect a road sign using shape features. At first, the color information that is not used in road signs is removed from an image. Next, edges except for circular and triangle ones are removed to choose sign shape. In the recognition process, normalized cross correlation operation is carried out to the two-dimensional differentiation pattern of a sign, and the accurate and efficient method for detecting the road sign is realized. Moreover, the real-time operation in a software base was realized by holding down calculation cost, maintaining highly precise sign detection and recognition. Specifically, it becomes specifically possible to process by 0.1 sec(s)/frame using a general-purpose PC (CPU: Pentium4 1.7GHz). As a result of in-vehicle experimentation, our system could process on real time and has confirmed that detection and recognition of a sign could be performed correctly.

  13. Automatic adjustment of astrochronologic correlations

    Science.gov (United States)

    Zeeden, Christian; Kaboth, Stefanie; Hilgen, Frederik; Laskar, Jacques

    2017-04-01

    Here we present an algorithm for the automated adjustment and optimisation of correlations between proxy data and an orbital tuning target (or similar datasets as e.g. ice models) for the R environment (R Development Core Team 2008), building on the 'astrochron' package (Meyers et al.2014). The basis of this approach is an initial tuning on orbital (precession, obliquity, eccentricity) scale. We use filters of orbital frequency ranges related to e.g. precession, obliquity or eccentricity of data and compare these filters to an ensemble of target data, which may consist of e.g. different combinations of obliquity and precession, different phases of precession and obliquity, a mix of orbital and other data (e.g. ice models), or different orbital solutions. This approach allows for the identification of an ideal mix of precession and obliquity to be used as tuning target. In addition, the uncertainty related to different tuning tie points (and also precession- and obliquity contributions of the tuning target) can easily be assessed. Our message is to suggest an initial tuning and then obtain a reproducible tuned time scale, avoiding arbitrary chosen tie points and replacing these by automatically chosen ones, representing filter maxima (or minima). We present and discuss the above outlined approach and apply it to artificial and geological data. Artificial data are assessed to find optimal filter settings; real datasets are used to demonstrate the possibilities of such an approach. References: Meyers, S.R. (2014).

    The use of video equipment as instrumentation has been increasing steadily over the past decade. An indication of this trend can be found close to home: notice how rapidly the number of television (TV) displays has grown at our technical exhibits. It is this exhibited equipment and other equipment like it which form the subject of this summary. We will limit our discussions to readily available hardware (and a little software) and leave reports of the leading edge development work to other issues of this journal. We hope, in this manner, to present useful information to those who need to apply video to their instrumen-tation problems now. Along the way we will occasionally indicate what equipment might soon result from current research, but our clear emphasis will be on the state of the art of accessible instrumentation video.

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market. Thus issuers are, in Romanian Law perspective, special company that should comply special rule regarding board of administration and general shareholders meeting.

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

    1978-08-01

    The demand for higher accuracy and a shorter delay in the analysis together with better objectifiability and data security needed in safeguards, lead to the automation of a mass spectrometer. Starting with a continuous feeding of samples via a high vacuum lock and including the subsequent heating, focussing and scanning of the samples as well as the final evaluation of the source data (taking alpha spectrometry and the weights required for the isotope dilution technique into account), the mass spectrometric procedure was completely automated. For this purpose, a serial CH-5 instrument of varian mat was modified to be operated by a varian 620/I computer. A newly developed three chamber high vacuum lock was attached to this system and the final evaluation is made with an IBM 370. The system has been used in operation for the isotope analysis of U, Pu and Nd for one year. Major breakdowns of the hardware did not occur, however, the computer programmes had to be steadily improved according to the changing characteristics of the samples. Compared to manual operation, the automat is superior in its throughput and speed of analysing series of similar samples. The automatic procedure objectifies the analysis and the complete evaluation ensures a better data security. (Orig./HP). (author)

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    A fire at a nuclear power plant (NPP) has the potential to damage structures, systems, and components important to safety, if not promptly detected and suppressed. At Browns Ferry Nuclear Power Plant on March 22, 1975, a fire in the reactor building damaged electrical power and control systems. Damage to instrumentation cables impeded the function of both normal and standby reactor coolant systems, and degraded the operators’ plant monitoring capability. This event resulted in additional NRC involvement with utilities to ensure that NPPs are properly protected from fire as intended by the NRC principle design criteria (i.e., general design criteria 3, Fire Protection). Current guidance and methods for both deterministic and performance based approaches typically make conservative (bounding) assumptions regarding the fire-induced failure modes of instrumentation cables and those failure modes effects on component and system response. Numerous fire testing programs have been conducted in the past to evaluate the failure modes and effects of electrical cables exposed to severe thermal conditions. However, that testing has primarily focused on control circuits with only a limited number of tests performed on instrumentation circuits. In 2001, the Nuclear Energy Institute (NEI) and the Electric Power Research Institute (EPRI) conducted a series of cable fire tests designed to address specific aspects of the cable failure and circuit fault issues of concern1. The NRC was invited to observe and participate in that program. The NRC sponsored Sandia National Laboratories to support this participation, whom among other things, added a 4-20 mA instrumentation circuit and instrumentation cabling to six of the tests. Although limited, one insight drawn from those instrumentation circuits tests was that the failure characteristics appeared to depend on the cable insulation material. The results showed that for thermoset insulated cables, the instrument reading tended to drift

    The use of endoluminal stents has been proposed for the management of fistulas and anastomotic strictures after bariatric surgery. The objective of our study was to determine the success of endoscopically placed, self-expandable metal stents (SEMS) in bariatric patients specifically with either chronic persistent anastomotic or staple line leaks/fistulas or chronic, persistent anastomotic strictures. We treated 21 patients including 5 with chronic staple line leaks/fistulas (4 from the gastric sleeve after biliopancreatic diversion with duodenal switch [BPD/DS] and 1 after removal of an eroding laparoscopic adjustable gastric band) and 16 with chronic anastomotic strictures (15 at the gastrojejunostomy after Roux-en-Y gastric bypass and 1 at the duodenoileal anastomosis after BPD/DS). Patients with early leaks or anastomotic strictures were excluded. All but one of these patients had been referred to our institution after chronic treatment elsewhere was unsuccessful with prior stent placement for fistulas or multiple endoscopic dilations for strictures. Their bariatric operations had been performed a mean of 386 days beforehand. Stent placement was performed successfully in all patients without complications but was successful in only 4 of 21 patients (19%)-2 with chronic fistulas and 2 with chronic anastomotic strictures. Stent migration occurred in 10 patients (47%); the migrated stents were removed/replaced endoscopically in 7 patients but required elective operative removal in 3 with concomitant correction of the leak, fistula, or anastomotic stricture; none were operated emergently. Only 4 of 21 patients with a chronic persistent leak or anastomotic stricture were treated definitively using a SEMS. Although endoluminal stents may not lead to resolution of a chronic leak or stricture, SEMS may suppress ongoing sepsis and allow patients to undergo nutritional resuscitation orally before operative correction.

    To investigate the respiratory motion of metal clips or surgical staples placed in the gastric wall for planning of radiation therapy in gastric cancer patients. This study examined 15 metal markers in the gastric walls of 12 patients with gastric cancer treated with external-beam photon RT. Motion assessment was analyzed in 41 respiratory phases covering 20 s acquired with computed tomography (CT) in the RT position using 320-multislice CT. The intra-fraction displacement was assessed in the cranio-caudal (CC), antero-posterior (AP), and right-left (RL) directions. Motion in the CC direction showed a very strong correlation (R 2 > 0.7) with the respiratory curve in all 15 markers. The mean (+/− SD) intra-fractional gastric motion (maximum range of displacement) was 12.5 (+/− 3.4) mm in the CC, 8.3 (+/− 2.2) mm in the AP, and 5.5 (+/− 3.0) mm in the RL direction. No significant differences in magnitude of motion were detected in the following: a) among the upper (n = 6), middle (n = 4), and lower (n = 5) stomach regions; b) between metal clips (n = 5) and surgical staples (n = 10); and c) between full (n = 9) and empty (n = 6) stomachs. Motion in primary gastric tumor was evaluated with 320-multislice CT. According to this study, the 95th percentile values from the cumulative distributions of the RL, AP, and CC direction were 6.3 mm, 9.0 mm, and 13.6 mm, respectively

    During normal operation, protection systems are on standby and possible failure of system components may therefore go undetected. Their ability to function as intended, should they be initiated after a long period of time, is thus questionable. For this reason, French as well as international rules require that protection systems be subjected to periodic tests. Because of the equipment available when the units in the French 900-MW(electric) series were designed, the instrumentation and control systems were equipped with manual periodic test systems. This was the case with the reactor protection system (RPS) periodic test equipment where the manual procedures relied on the manipulation of a large number of switches and push buttons. This manual test equipment has been successfully replaced on the 28 units in the French 900-MW(electric) series by the automatic tester discussed in this paper

Actuation is based upon either a sudden decrease in core pressure drop or the pressure drop decreases below a predetermined minimum value. The automatic control rod includes a pressure regulating device whereby a controlled decrease in operating pressure due to reduced coolant flow does not cause the rod to drop into the core.

    Two kinds of cognitive processes can be distinguished: Automatic processes, which are mostly subconscious, are learned and changed very slowly, and are not subject to the capacity limitations of working memory, and strategic processes, which are conscious, are subject to capacity limitations......, and can easily be adapted to situational circumstances. Both the perception of advertising and the way advertising influences brand evaluation involves both processes. Automatic processes govern the recognition of advertising stimuli, the relevance decision which determines further higher-level processing...

    International audience; Control system programs are usually validated by testing prior to their deployment. Unfortunately, testing is not exhaustive and therefore it is possible that a program which passed all the required tests still contains errors. In this paper we apply techniques of automatic verification to a control program written in ladder logic. A model is constructed mechanically from the ladder logic program and subjected to automatic verification against requirements that include...

  5. Automatic terrain modeling using transfinite element analysis

    KAUST Repository

    Collier, Nathan

    2010-05-31

    An automatic procedure for modeling terrain is developed based on L2 projection-based interpolation of discrete terrain data onto transfinite function spaces. The function space is refined automatically by the use of image processing techniques to detect regions of high error and the flexibility of the transfinite interpolation to add degrees of freedom to these areas. Examples are shown of a section of the Palo Duro Canyon in northern Texas.

  6. The problem of automatic identification of concepts

    International Nuclear Information System (INIS)

    Andreewsky, Alexandre

    1975-11-01

    This paper deals with the problem of the automatic recognition of concepts and describes an important language tool, the ''linguistic filter'', which facilitates the construction of statistical algorithms. Certain special filters, of prepositions, conjunctions, negatives, logical implication, compound words, are presented. This is followed by a detailed description of a statistical algorithm allowing recognition of pronoun referents, and finally the problem of the automatic treatment of negatives in French is discussed [fr

    2015-01-01

    this issue is addressed. We propose an automatic continuation method, where the material penalization parameter is included as a new variable in the problem and a constraint guarantees that the requested penalty is eventually reached. The numerical results suggest that this approach is an appealing...... alternative to continuation methods. Automatic continuation also generally obtains better designs than the classical formulation using a reduced number of iterations....

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

  10. AC resistance measuring instrument

    Hof, P.J.

    1983-10-04

    An auto-ranging AC resistance measuring instrument for remote measurement of the resistance of an electrical device or circuit connected to the instrument includes a signal generator which generates an AC excitation signal for application to a load, including the device and the transmission line, a monitoring circuit which provides a digitally encoded signal representing the voltage across the load, and a microprocessor which operates under program control to provide an auto-ranging function by which range resistance is connected in circuit with the load to limit the load voltage to an acceptable range for the instrument, and an auto-compensating function by which compensating capacitance is connected in shunt with the range resistance to compensate for the effects of line capacitance. After the auto-ranging and auto-compensation functions are complete, the microprocessor calculates the resistance of the load from the selected range resistance, the excitation signal, and the load voltage signal, and displays of the measured resistance on a digital display of the instrument. 8 figs.

    Remote science operations require automated systems that can both act and react with minimal human intervention. One such vision is that of an intelligent instrument that collects data in an automated fashion, and based on what it learns, decides which new measurements to take. This innovation implements experimental design and unites it with data analysis in such a way that it completes the cycle of learning. This cycle is the basis of the Scientific Method. The three basic steps of this cycle are hypothesis generation, inquiry, and inference. Hypothesis generation is implemented by artificially supplying the instrument with a parameterized set of possible hypotheses that might be used to describe the physical system. The act of inquiry is handled by an inquiry engine that relies on Bayesian adaptive exploration where the optimal experiment is chosen as the one which maximizes the expected information gain. The inference engine is implemented using the nested sampling algorithm, which provides the inquiry engine with a set of posterior samples from which the expected information gain can be estimated. With these computational structures in place, the instrument will refine its hypotheses, and repeat the learning cycle by taking measurements until the system under study is described within a pre-specified tolerance. We will demonstrate our first attempts toward achieving this goal with an intelligent instrument constructed using the LEGO MINDSTORMS NXT robotics platform.

    1992-11-01

    Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented

  20. Ontology Based Vocabulary Matching for Oceanographic Instruments

    Data integration act as the preliminary entry point as we enter the era of big data in many scientific domains. However the reusefulness of various dataset has met the hurdle due to different initial of interests of different parties, therefore different vocabularies in describing similar or semantically related concepts. In this scenario it is vital to devise an automatic or semi-supervised algorithm to facilitate the convergence of different vocabularies. The Ocean Data Interoperability Platform (ODIP) seeks to increase data sharing across scientific domains and international boundaries by providing a forum to harmonize diverse regional data systems. ODIP participants from the US include the Rolling Deck to Repository (R2R) program, whose mission is to capture, catalog, and describe the underway/environmental sensor data from US oceanographic research vessels and submit the data to public long-term archives. In an attempt to harmonize these regional data systems, especially vocabularies, R2R recognizes the value of the SeaDataNet vocabularies served by the NERC Vocabulary Server (NVS) hosted at the British Oceanographic Data Centre as a trusted, authoritative source for describing many oceanographic research concepts such as instrumentation. In this work, we make use of the semantic relations in the vocabularies served by NVS to build a Bayesian network and take advantage of the idea of entropy in evaluating the correlation between different concepts and keywords. The performance of the model is evaluated against matching instruments from R2R against the SeaDataNet instrument vocabularies based on calculated confidence scores in the instrument pairings. These pairings with their scores can then be analyzed for assertion growing the interoperability of the R2R vocabulary through its links to the SeaDataNet entities.
