    Presented here is a 32 × 32 optical switch for telecommunications applications capable of reconfiguring at speeds of up to 12 microseconds. The free space switching mechanism in this interconnect is a digital micromirror device (DMD) consisting of a 2D array of 10.8μm mirrors optimized for implementation at 1.55μm. Hinged along one axis, each micromirror is capable of accessing one of two positions in binary fashion. In general reflection based applications this corresponds to the ability to manifest only two display states with each mirror, but by employing this binary state system to display a set of binary amplitude holograms, we are able to access hundreds of distinct locations in space. We previously demonstrated a 7 × 7 switch employing this technology, providing a proof of concept device validating our initial design principles but exhibiting high insertion and wavelength dependent losses. The current system employs 1920 × 1080 DMD, allowing us to increase the number of accessible ports to 32 × 32. Adjustments in imaging, coupling component design and wavelength control were also made in order to improve the overall loss of the switch. This optical switch performs in a bit-rate and protocol independent manner, enabling its use across various network fabrics and data rates. Additionally, by employing a diffractive switching mechanism, we are able to implement a variety of ancillary features such as dynamic beam pick-off for monitoring purposes, beam division for multicasting applications and in situ attenuation control.

    The ITER equatorial port visible/infrared wide angle viewing system concept is developed from the measurement requirements. The proposed solution situates 4 viewing systems in the equatorial ports 3, 9, 12, and 17 with 4 views each (looking at the upper target, the inner divertor, and tangentially left and right). This gives sufficient coverage. The spatial resolution of the divertor system is 2 times higher than the other views. For compensation of vacuum-vessel movements, an optical hinge concept is proposed. Compactness and low neutron streaming is achieved by orienting port plug doglegs horizontally. Calibration methods, risks, and R and D topics are outlined.

  4. The elusive concept of brain connectivity.

    PubMed

    Horwitz, Barry

    2003-06-01

    Neurons and neural populations do not function as islands onto themselves. Rather, they interact with other such elements through their afferent and efferent connections in an orchestrated manner so as to enable different sensorimotor and cognitive tasks to be performed. The concept of functional connectivity and the allied notion of effective connectivity were introduced to designate the functional strengths of such interactions. Functional neuroimaging methods, especially PET and fMRI, have been used extensively to evaluate the functional connectivity between different brain regions. After providing a brief historical review of these notions of brain connectivity, I argue that the conceptual formulations of functional and effective connectivity are far from clear. Specifically, the terms functional and effective connectivity are applied to quantities computed on types of functional imaging data (e.g., PET, fMRI, EEG) that vary in spatial, temporal, and other features, using different definitions (even for data of the same modality) and employing different computational algorithms. Until it is understood what each definition means in terms of an underlying neural substrate, comparisons of functional and/or effective connectivity across studies may appear inconsistent and should be performed with great caution.

    Having spent their first century anchored to a biomedical model of practice, physiotherapists have been increasingly interested in exploring new models and concepts that will better equip them for serving the health-care needs of 21st century clients/patients. Connectivity offers one such model. With an extensive philosophical background in phenomenology, symbolic interactionism, structuralism, and postmodern research, connectivity resists the prevailing western biomedical view that health professionals should aim to increase people's independence and autonomy, preferring instead to identify and amplify opportunities for collaboration and co-dependence. Connectivity critiques the normalization that underpins modern health care, arguing that our constant search for deviance is building stigma and discrimination into our everyday practice. It offers provocative opportunities for physiotherapists to rethink some of the fundamental tenets of their profession and better align physiotherapy with 21st century societal expectations. In this paper, we provide a background to the place connectivity may play in future health care, and most especially future physiotherapy practice. The paper examines some of the philosophical antecedents that have made connectivity an increasingly interesting and challenging concept in health care today. PMID:27050116

    2011-01-01

    This review attempts to place the concept of connectivity from increasingly sophisticated neuroimaging data analysis methodologies within the field of epilepsy research. We introduce the more principled connectivity terminology developed recently in neuroimaging and review some of the key concepts related to the characterization of propagation of epileptic activity using what may be called traditional correlation-based studies based on EEG. We then show how essentially similar methodologies, and more recently models addressing causality, have been used to characterize whole-brain and regional networks using functional MRI data. Following a discussion of our current understanding of the neuronal system aspects of the onset and propagation of epileptic discharges and seizures, we discuss the most advanced and ambitious framework to attempt to fully characterize epileptic networks based on neuroimaging data.

    For effective catchment management and intervention in hydrological systems a process-based understanding of hydrological connectivity is required so that: i) conceptual rather than solely empirical understanding drives how systems are interpreted; and ii) there is an understanding of how continuous flow fields develop under different sets of environmental conditions to enable managers to know when, where and how to intervene in catchment processes successfully. In order to direct future research into process-based hydrological connectivity this paper: i) evaluates the extent to which different concepts of hydrological connectivity have emerged from different approaches to measure and predict flow in different environments; ii) discusses the extent to which these different concepts are mutually compatible; and iii) assesses further research to contribute to a unified understanding of hydrological processes. Existing research is categorised into five different approaches to investigating hydrological connectivity: i) evaluating soil-moisture patterns (soil-moisture connectivity); ii) understanding runoff patterns and processes on hillslopes (flow-process connectivity); iii) investigating topographic controls (terrain-connectivity) including the impact of road networks on hydrological connectivity and catchment runoff; iv) developing models to explore and predict hydrological connectivity; and v) developing indices of hydrological connectivity. Analysis of published research suggests a relationship between research group, approach, geographic setting and the interpretation of hydrological connectivity. For further understanding of hydrological connectivity our knowledge needs to be developed using a range of techniques and approaches, there should be common understandings between researchers approaching the concept from different perspectives, and these meanings need to be communicated effectively with those responsible for land management.

    1971-01-01

    A preliminary study of containment systems for aircraft landing on elevated STOL-ports was conducted as part of an overall study of human acceptance problems associated with STOL operations. The study included a survey and feasibility study of different concepts and a computer analysis of four arrestment systems. The principal conclusion was that a system referred to as the FAA system appears to offer the greatest promise. In this system, standard arresting gear cables are stretched across the roof-top, at roughly 100-foot intervals, but are shielded over the 100-foot-wide primary landing strip. Thus a pilot can land with an arresting hook down, but will not contact the cable unless he swerves off the landing strip, either because he has made a bad landing, or because his landing gear has failed. It was also noted that a suitable curb or guard rail should be developed. Presently available arresting gears and nylon net barriers were considered satisfactory for the overshoot problem.

  15. A Multivariate Granger Causality Concept towards Full Brain Functional Connectivity

    PubMed Central

    Schmid-Hertel, Nicole; Witte, Herbert; Wismüller, Axel; Leistritz, Lutz

    2016-01-01

    Detecting changes of spatially high-resolution functional connectivity patterns in the brain is crucial for improving the fundamental understanding of brain function in both health and disease, yet still poses one of the biggest challenges in computational neuroscience. Currently, classical multivariate Granger Causality analyses of directed interactions between single process components in coupled systems are commonly restricted to spatially low- dimensional data, which requires a pre-selection or aggregation of time series as a preprocessing step. In this paper we propose a new fully multivariate Granger Causality approach with embedded dimension reduction that makes it possible to obtain a representation of functional connectivity for spatially high-dimensional data. The resulting functional connectivity networks may consist of several thousand vertices and thus contain more detailed information compared to connectivity networks obtained from approaches based on particular regions of interest. Our large scale Granger Causality approach is applied to synthetic and resting state fMRI data with a focus on how well network community structure, which represents a functional segmentation of the network, is preserved. It is demonstrated that a number of different community detection algorithms, which utilize a variety of algorithmic strategies and exploit topological features differently, reveal meaningful information on the underlying network module structure.

  19. On basic conditions to generate multi-adjoint concept lattices via Galois connections

    This paper introduces sufficient and necessary conditions with respect to the fuzzy operators considered in a multi-adjoint frame under which the standard combinations of multi-adjoint sufficiency, possibility, and necessity operators form (antitone or isotone) Galois connections. The underlying idea is to study the minimal algebraic requirements so that the concept-forming operators (defined using the same syntactical form than the extension and intension operators of multi-adjoint concept lattices) form a Galois connection. As a consequence, given a relational database, we have much more possibilities to construct concept lattices associated with it, so that we can choose the specific version which better suits the situation.

    1981-06-01

    For a number of years, researchers at the Pacific Northwest Laboratory have been developing processes and equipment for converting high-level liquid wastes to solid forms. One of these processes is the Spray Calciner/In-Can Melter system. To immobilize high-level liquid wastes, this system must be operated remotely, and the calcine must be reliably conveyed from the calciner to the melting furnace. A concept for such a remote conveyance system was developed at the Pacific Northwest Laboratory, and equipment was tested under full-scale, nonradioactive conditions. This concept and the design of demonstration equipment are described, and the results of equipment operation during experimental runs of 7 d are presented. The design includes a connecting section and its associated systems - a canister sypport and alignment concept and a weight-monitoring system for the melting furnace. Overall, the runs demonstrated that the concept design is an acceptable method of connecting the two pieces of process equipment together. Although the connecting section has not been optimized in all areas of concern, it provides a first-generation design of a production-oriented system.

  5. Science conceptions and connections: How third graders engage in inquiry to learn science

    NASA Astrophysics Data System (ADS)

    Marston, Susan Hemphill

    In this teacher-research study, I explore the process of inquiring to learn science from the perspective of third graders. As a teacher-researcher, this study was conducted in my third grade classroom over the course of a year. I used qualitative research methods to construct five ethnographic case studies of my students. The study focused on (1) third graders' conceptions of science and being scientists. It examined how these conceptions changed (or did not change) throughout the year, and (2) the connections that these students made (or did not make) between science and reading, writing, talking, and listening. Student interviews, observations, and written documentation, as well as my own reflective journal, informed the case studies. The data suggests that these third graders' conceptions of being a scientist are directly related to their definitions of science. These third graders compare their actions to their conceptions of science to determine if they are a scientist. In addition, the data reveals that these students' reading, writing, talking, and listening experiences influence their science conceptions. In particular, I identify three variables, context, definition, and relationships that interact to contribute (or distract) from these third graders' thinking about themselves as scientists. The context in which science is explored plays an important role in these third graders' conceptions. The places where science is performed and who conceives the original ideas to be tested are important conditions. These third graders' definition of science and the relationships they construct within the curriculum and each other also influence their conceptions of being scientists. Overall, this study finds that these third graders use the processes of reading, writing, talking, and listening to enhance their science understanding. It also points to the importance of having the students engage in scientific inquiry both in and out of the classroom. This research

  6. The Series Connected Buck Boost Regulator Concept for High Efficiency Light Weight DC Voltage Regulation

    NASA Technical Reports Server (NTRS)

    Birchenough, Arthur G.

    2003-01-01

    Improvements in the efficiency and size of DC-DC converters have resulted from advances in components, primarily semiconductors, and improved topologies. One topology, which has shown very high potential in limited applications, is the Series Connected Boost Unit (SCBU), wherein a small DC-DC converter output is connected in series with the input bus to provide an output voltage equal to or greater than the input voltage. Since the DC-DC converter switches only a fraction of the power throughput, the overall system efficiency is very high. But this technique is limited to applications where the output is always greater than the input. The Series Connected Buck Boost Regulator (SCBBR) concept extends partial power processing technique used in the SCBU to operation when the desired output voltage is higher or lower than the input voltage, and the implementation described can even operate as a conventional buck converter to operate at very low output to input voltage ratios. This paper describes the operation and performance of an SCBBR configured as a bus voltage regulator providing 50 percent voltage regulation range, bus switching, and overload limiting, operating above 98 percent efficiency. The technique does not provide input-output isolation.

    2009-04-01

    Simply placing electronic geoscience resources such as datasets, methods, ontologies, workflows and articles in a digital library or cyberinfrastructure does not mean that they will be used successfully by other researchers or educators. It is also necessary to provide the means to locate potentially useful content, and to understand it. Without suitable provision for these needs, many useful resources will go undiscovered, or else will be found but used inappropriately. In this article, we describe an approach to discovering, describing and understanding e-resources based on the notion that meaning is carried in the interconnections between resources and the actors in the cyberinfrastructure (including individuals, groups, organizations), as well as by ontologies and conventional metadata. Navigation around this universe is achieved by implementing the idea of perspectives as dynamic, conceptual views (defined by SPARQL-like queries against an OWL schema) that not only act as filters, but also dynamically promote and demote concepts, relationships and properties according to their immediate relevance. We describe a means to represent a wide variety of interactions between resources using the notion of a knowledge nexus, and we illustrate its use with resources and actors from the Geosciences Network (GEON) cyberinfrastructure community. We also closely link browsing and visualizing strategies to our nexus, drawing on ideas from semiotics to move resources and connections not currently of interest from the foreground to the background, and vice versa, using a new form of adaptive perspective. We illustrate our ideas via ConceptVista, an open-source concept mapping application that provides rich, visual depictions of the resources, cyber-community and myriad connections between them. Examples are presented that show how geoscientific knowledge can be explored not only via ontological structure, but also by use cases, social networks, citation graphs and organization

    The volumetric efficiency and power of internal combustion engines is improved with an intake port having an intake nozzle, a venturi, and a surge chamber. The venturi is located almost halfway upstream the intake port between the intake valves and the intake plenum enabling the venturi throat diameter to be exceptionally small for providing an exceptionally high ram velocity and an exceptionally long and in turn high efficiency diffuser flowing into the surge chamber. The intake port includes an exceptionally large surge chamber volume for blow down of the intake air into the working cylinder of the engine.

  13. Focal Venous Hypertension as a Pathophysiologic Mechanism for Tissue Hypertrophy, Port-Wine Stains, the Sturge-Weber Syndrome, and Related Disorders: Proof of Concept with Novel Hypothesis for Underlying Etiological Cause (An American Ophthalmological Society Thesis)

    PubMed Central

    Parsa, Cameron F.

    2013-01-01

    Purpose: To provide an in-depth re-examination of assumed causes of tissue hypertrophy, port-wine stains, and the Sturge-Weber, Cobb, Klippel-Trénaunay, and related syndromes to support an alternative unifying pathophysiologic mechanism of venous dysplasia producing focal venous hypertension with attendant tissue responses; to provide proof of concept with new patient data; to propose a novel etiological hypothesis for the venous dysplasia in these syndromes and find supportive evidence. Methods: Data from 20 patients with port-wine stains and corneal pachymetry readings was collected prospectively by the author in an institutional referral-based practice. The literature was searched using MEDLINE, and articles and textbooks were obtained from the bibliographies of these publications. Results: Newly obtained dermatologic, corneal pachymetry, fundus ophthalmoscopic, ocular and orbital venous Doppler ultrasonography, and magnetic resonance imaging findings in patients with the Sturge-Weber syndrome or isolated port-wine stains, along with published data, reveal diffusely thickened tissues and neural atrophy in all areas associated with venous congestion. Conclusions: Contrary to traditional understanding, signs and symptoms in the Sturge-Weber and related syndromes, including both congenital and acquired port-wine stains, are shown to arise from effects of localized primary venous dysplasia or acquired venous obstruction rather than neural dysfunction, differentiating these syndromes from actual phacomatoses. Effects of focal venous hypertension are transmitted to nearby areas via compensatory collateral venous channels in the above conditions, as in the Parkes Weber syndrome. A novel underlying etiology—prenatal venous thrombo-occlusion—is proposed to be responsible for the absence of veins with persistence and enlargement of collateral circulatory pathways with data in the literature backing this offshoot hypothesis. The mechanism for isolated pathologic

    Aboriginal people across Australia suffer significant health inequalities compared with the non-Indigenous population. Evidence indicates that inroads can be made to reduce these inequalities by better understanding social and cultural determinants of health, applying holistic notions of health and developing less rigid definitions of wellbeing. The following article draws on qualitative research on Victorian Aboriginal peoples' relationship to their traditional land (known as Country) and its link to wellbeing, in an attempt to tackle this. Concepts of wellbeing, Country and nature have also been reviewed to gain an understanding of this relationship. An exploratory framework has been developed to understand this phenomenon focusing on positive (e.g., ancestry and partnerships) and negative (e.g., destruction of Country and racism) factors contributing to Aboriginal peoples' health. The outcome is an explanation of how Country is a fundamental component of Aboriginal Victorian peoples' wellbeing and the framework articulates the forces that impact positively and negatively on this duality. This review is critical to improving not only Aboriginal peoples' health but also the capacity of all humanity to deal with environmental issues like disconnection from nature and urbanisation.

  6. The history of re-connection and the concept of the solar wind plasma with relatively small electrical conductivity

    Chertkov, A. D.

    1995-01-01

    Petschek's 're-connection' model, aspiring to be universal, treated as a boundary problem meets unresolvable difficulties connected with impossibility to specify correctly boundary and initial conditions. This problem was incorrectly formulated. Hence, ineradicable logarithmic singularities occurred on the boundary surfaces. Attempts to eliminate them by incorporating the finite electrical conductivity are incorrect. This should lead to the change in the equation type, boundary condition type and in consequence to the change in solutions. Besides, the slow mode shocks cannot be driven by small internal source. As an alternative a new plasma concept is suggested. The state of fully ionized plasma in space depends completely on the entropy of the plasma heating source and on the process in which plasma is involved. The presumptive source of the solar wind creation - the induction electric field of the solar origin - has very low entropy. The state of plasma should be very far from the thermodynamic equilibrium. Debye's screening is not complete. The excitation of the powerful resonant self-consistent electric fields in plasma provides low electric conductivity. The MHD problems should be treated in frameworks of dissipative theories.

    Tsunami-induced currents present an obvious hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 and 2011) have coastal and port engineering practitioners begun to develop port-specific warning and response products that accurately assess the effects of tsunami-induced currents in addition to overland flooding and inundation. The hazard from strong currents induced by far-field tsunami remains an underappreciated risk in the port and maritime community. In this paper, we will discuss the history of tsunami current observations in ports, look into the current state of the art in port tsunami hazard assessment and discuss future research trends.

    Equivalent networks can be used in power system simulation to equipment or computer time and memory space. In this paper, an interative method is developed for synthesizing one-port equivalent networks by the removal of poles corresponding to resonances of the driving-point impedance or admittance function. This results in networks formed by the series or parallel connection of modular RLC circuits. The RLC values are calculated using a parameter-optimization technique. Multi-port equivalent networks are first configured as ..pi.. or T form composed of one-port network branches and the latters are then synthesized by the proposed method for one-port equivalent networks.

    2015-02-01

    Reduced port laparoscopic surgery has been used increasingly. It is a concept that has grown out of the various efforts aimed at minimally invasive surgery, with SILS being the ultimate reduced port technique. Reduced port laparoscopic surgery has been used to perform sleeve gastrectomy in bariatric surgery and excision of benign gastric submucosal tumor, applications that generally do not require lymph node dissection or complicated reconstruction. It can be done safely, result in a permanent cure, and offer good cosmetic outcomes. Reduced port laparoscopic surgery for gastric cancer has a short history, and its usefulness has not yet been fully established. This review describes the present situation and challenges faced as well as standardized procedures and the future prospects of reduced port laparoscopic gastrectomy for gastric cancer, which my team performs almost daily. These aspects of reduced port laparoscopic surgery are presented in light of the literature. PMID:25496345

    Single port thoracic surgery, reduced port surgery and needlescopic surgery attract attention as one of the minimally invasive surgery in thoracic surgery recently. Single port thoracic surgery was advocated by Rocco in 2004, it was reported usefulness of single port thoracic surgery for primary spontaneous pneumothorax. The surgical procedure as single (or reduced) port thoracic surgery is roughly divided into the following. One is operated with instruments inserted from the single extended incision, and the other is operated with instruments punctured without extending incision. It is not generally complicated procedures in single port thoracic surgery. Primary spontaneous pneumothorax and biopsy for lung and pleura are considered the surgical indication for single (or reduced) port surgery. It is revealed that single port surgery for primary spontaneous pneumothorax is less invasive than conventional surgery. Single port and reduced port thoracic surgery will spread furthermore in the future. PMID:27440029

Transport network modelling enable the development of mathematical models used in evaluating the reliability and vulnerability. Nodes or link disruption could have an important impact over transport network users. In our paper we investigates the Romanian road network vulnerability related to Danube crossing versus maritime ports (Constanta and Mangalia) and its mitigation by improving network topology. We use Visum software to promote a methodology to assess road transport network vulnerability versus Romanian seaports and we propose some solutions to reduce probability of road transport network to fail.

    With over 360 ports of entry and 20 million sea, truck, and rail containers entering the United States every year, port facilities pose a large risk to security. Securing these ports and monitoring the variety of traffic that enter and leave is a major task. To accomplish this, the authors propose a fully distributed building block approach to port security. Based on prior work accomplished in the design and fielding of an intelligent transportation system in the United States, building blocks can be assembled, mixed and matched, and scaled to provide a comprehensive security system. Network blocks, surveillance blocks, sensor blocks, and display blocks will be developed and demonstrated in the lab, and at an inland port. The following functions will be demonstrated and scaled through analysis and demonstration: Barge tracking, credential checking, container inventory, vehicle tracking, and situational awareness. The concept behind this research is "any operator on any console can control any device at any time."

    Eberle, Francis Quick

    In the last three decades, the United States has experienced many science education reform initiatives resulting in mixed success. Recently, research has found teachers' beliefs about their content and teaching have influence on what is taught. This investigation attempts to learn about the relationship between middle school teachers' beliefs and knowledge regarding the coherence and connectedness of science concepts and their classroom practice. This phenomenological investigation used an inductive qualitative research approach with multiple instruments and processes including; a survey, interviews, classroom observations, concept maps and classroom materials for data. The results suggest that middle school science teachers' ability to teach science in a connected and coherent fashion may be tied to their mental schema for organizing science ideas, curriculum materials, and their reflections on what they are teaching and why. Further research should help isolate and mitigate outside influences leading to a better understanding of teachers' beliefs about science.

    2010-04-15

    Implantation of subcutaneous port systems is routinely performed in patients requiring repeated long-term infusion therapy. Ultrasound- and fluoroscopy-guided implantation under local anesthesia is broadly established in interventional radiology and has decreased the rate of complications compared to the surgical approach. In addition, interventional radiology offers the unique possibility of simultaneous management of venous occlusion. We present a technique for recanalization of central venous occlusion and angioplasty combined with port placement in a single intervention which we performed in two patients. Surgical port placement was impossible owing to occlusion of the superior vena cava following placement of a cardiac pacemaker and occlusion of multiple central veins due to paraneoplastic coagulopathy, respectively. In both cases the affected vessel segments were dilated with balloon catheters and the port systems were placed thereafter. After successful dilatation, the venous access was secured with a 25-cm-long, 8-Fr introducer sheath, a subcutaneous pocket prepared, and the port catheter tunneled to the venipuncture site. The port catheter was introduced through the sheath with the proximal end connected to a 5-Fr catheter. This catheter was pulled through the tunnel in order to preserve the tunnel and, at the same time, allow safe removal of the long sheath over the wire. The port system functioned well in both cases. The combination of recanalization and port placement in a single intervention is a straightforward alternative for patients with central venous occlusion that can only be offered by interventional radiology.

  16. ROCKET PORT CLOSURE

    DOEpatents

    Mattingly, J.T.

    1963-02-12

    This invention provides a simple pressure-actuated closure whereby windowless observation ports are opened to the atmosphere at preselected altitudes. The closure comprises a disk which seals a windowless observation port in rocket hull. An evacuated instrument compartment is affixed to the rocket hull adjacent the inner surface of the disk, while the outer disk surface is exposed to the atmosphere through which the rocket is traveling. The pressure differential between the evacuated instrument compartment and the relatively high pressure external atmosphere forces the disk against the edge of the observation port, thereby effecting a tight seai. The instrument compartment is evacuated to a pressure equal to the atmospheric pressure existing at the altitude at which it is desiretl that the closure should open. When the rocket reaches this preselected altitude, the inwardly directed atmospheric force on the disk is just equaled by the residual air pressure force within the instrument compartment. Consequently, the closure disk falls away and uncovers the open observation port. The separation of the disk from the rocket hull actuates a switch which energizes the mechanism of a detecting instrument disposed within the instrument compartment. (AE C)

    2016-01-01

    The aim of this prospective study was to demonstrate the feasibility of the conic coupling connection as a novel approach for the retention of immediately loaded, titanium-reinforced, temporary fixed partial restorations. The patients received a fixed, immediate partial restoration, attached using the conic coupling connection to two implants placed in a fresh extraction socket. Changes in marginal peri-implant bone level or probing depth measurements, biologic or technical complications, and any other adverse event were recorded at yearly follow-ups up to 3 years after implantation. A total of 78 implants placed in 39 patients reached the 3-year follow-up. A trend of bone overgrowth over the implant platform (mean: 0.2 mm) and a complete fill of the vertical gap between the implant platform level and the first point of contact of the bone with the implant surface was seen after the 6-month follow-up. No disconnection of any prosthesis was noted during 3 years of full occlusal function. The results of this study suggest that titanium-reinforced, temporary partial restorations with conic coupling retention supported by immediate implants provide a successful, cost-effective treatment modality.

    The capacity through the use of robots with on board visual, NBC and HAZMAT sensors to rapidly and continuously screen convoys and staged exposed assets would be a force multiplier and measurably improve base and force protection at both inbound and outbound DOD and commercial facilities. This paper chronicles our experiment with the ODIS robot at the Ports of Los Angeles (POLA) and Long Beach (POLB) in July of 2003. POLA & POLB are responsible for moving over 30% of the United States trade goods. Queues of 54" container trucks routinely exceed 100 trucks, extending for over a mile from the port entrances. Spotted equipment and convoys at staging areas are a high visibility and value assets to a terrorist incident. The POLA/POLB scenario is also representative of TRANSCOM operations at the port of Basra during current operation in Iraq. The California Highway Patrol is responsible for physically inspecting these vehicles for roadworthiness and contraband, a dangerous and dirty job. We will also discuss the use of ODIS robots for this task.

  20. Mobile Lunar Base Concepts

    2004-02-01

    This paper describes three innovative concepts for a mobile lunar base. These concept combine design research for habitat architecture, mobility systems, habitability, radiation protection, human factors, and living and working environments on the lunar surface. The mobile lunar base presents several key advantages over conventional static base notions. These advantages concern landing zone safety, the requirement to move modules over the lunar surface, and the ability to stage mobile reconnaissance with effective systemic redundancy. All of these concerns lead to the consideration of a mobile walking habitat module and base design. The key issues involve landing zone safety, the ability to transport habitat modules across the surface, and providing reliability and redundancy to exploration traverses in pressurized vehicles. With self-ambulating lunar base modules, it will be feasible to have each module separate itself from its retro-rocket thruster unit, and walk five to ten km away from the LZ to a pre-selected site. These mobile modules can operate in an autonomous or teleoperated mode to navigate the lunar surface. At the site of the base, the mobile modules can combine together; make pressure port connections among themselves, to create a multi-module pressurized lunar base.

  1. ITER Port Interspace Pressure Calculations

    Carbajo, Juan J; Van Hove, Walter A

    2016-01-01

    The ITER Vacuum Vessel (VV) is equipped with 54 access ports. Each of these ports has an opening in the bioshield that communicates with a dedicated port cell. During Tokamak operation, the bioshield opening must be closed with a concrete plug to shield the radiation coming from the plasma. This port plug separates the port cell into a Port Interspace (between VV closure lid and Port Plug) on the inner side and the Port Cell on the outer side. This paper presents calculations of pressures and temperatures in the ITER (Ref. 1) Port Interspace after a double-ended guillotine break (DEGB) of a pipe of the Tokamak Cooling Water System (TCWS) with high temperature water. It is assumed that this DEGB occurs during the worst possible conditions, which are during water baking operation, with water at a temperature of 523 K (250 C) and at a pressure of 4.4 MPa. These conditions are more severe than during normal Tokamak operation, with the water at 398 K (125 C) and 2 MPa. Two computer codes are employed in these calculations: RELAP5-3D Version 4.2.1 (Ref. 2) to calculate the blowdown releases from the pipe break, and MELCOR, Version 1.8.6 (Ref. 3) to calculate the pressures and temperatures in the Port Interspace. A sensitivity study has been performed to optimize some flow areas.

    A paper describes the Octanode, a connecting node that facilitates the integration of multiple docking mechanisms, hatches, windows, and internal and external systems with the use of flat surfaces. The Octanode is a 26- faced Great Rhombicuboctahedron Archi medean solid with six octagonshaped panels, eight hexagon-shaped panels, and 12 square panels using three unique, simple, flat shapes to construct a spherical approximation. Each flat shape can be constructed with a variety of material and manufacturing techniques, such as honeycomb composite panels or a pocketed skinstringer configuration, using conventional means. The flat shapes can be connected together and sealed to create a pressurizable volume by the use of any conventional means including welding or fastening devices and sealant. The node can then be connected to other elements to allow transfer between those elements, or it could serve as an airlock. The Octanode can be manufactured on the ground and can be integrated with subsystems including hatches and ports. The node can then be transported to its intended location, whether on orbit or on surface. Any of the flat panels could be replaced by curved ones, turning the node into a copula. Windows may be placed on flat panes with optimal viewing angles that are not blocked by large connecting nodes. The advantage of using flat panels to represent a spherical approximation is that this allows for easier integration of subsystems and design features.

    A multi-port valve is described for regulating, as a function of ambient air having varying wind velocity and wind direction in an open-field control area, the distribution of a fluid, particularly carbon dioxide (CO{sub 2}) gas, in a fluid distribution system so that the control area remains generally at an elevated fluid concentration or level of said fluid. The multi-port valve generally includes a multi-port housing having a plurality of outlets there through disposed in a first pattern of outlets and at least one second pattern of outlets, and a movable plate having a plurality of apertures extending there through disposed in a first pattern of apertures and at least one second pattern of apertures. The first pattern of apertures being alignable with the first pattern of outlets and the at least one second pattern of apertures being alignable with the second pattern of outlets. The first pattern of apertures has a predetermined orientation with the at least one second pattern of apertures. For an open-field control area subject to ambient wind having a low velocity from any direction, the movable plate is positioned to equally distribute the supply of fluid in a fluid distribution system to the open-field control area. For an open-field control area subject to ambient wind having a high velocity from a given direction, the movable plate is positioned to generally distribute a supply of fluid in a fluid distribution system to that portion of the open-field control area located upwind. 7 figs.

    The circulator is a waveguide slotted bridge, at the center of which, along the axis of symmetry, is a set of toroidal ferrites arranged on a dielectric sleeve. As a result of this design, the overall dimensions of the circulator are reduced and the tuning of the circulator is simplified. An experimental model of a four port circulator was constructed in the 3-cm range of waves, with the direct losses of not over 1 dB and decouplings of not less than 19 dB in all the channels.

    We report a novel architecture that can be used to construct optical switch fabrics with very high port count and nanoseconds switching speed. It is well known that optical switch fabrics with very fast switching time and high port count are challenging to realize. Currently, one of the most promising solutions is based on a combination of wavelength-tunable lasers and the arrayed waveguide grating router (AWGR). To scale up the number of ports in such switches, a direct method is to use AWGRs with a high channel count. However, such AWGRs introduce very large crosstalk noise due to the close wavelength channel spacing. In this paper, we propose an architecture for realizing a high-port count optical switch fabric using a combination of low-port count AWGRs, optical ON-OFF gates and WDM couplers. Using this new methodology, we constructed a proof-of concept experiment to demonstrate the feasibility of a 256 x 256 optical switch fabric. To our knowledge, this port count is the highest ever reported for switch fabrics of this type. PMID:19550498

    Purpose. A transcutaneous port (T-port) has been developed allowing easy exchange of a catheter, which was fixed inside the device, using the Seldinger technique. The objective of the study was to test the T-port in patients who had percutaneous transhepatic biliary drainage (PTBD). Methods. The T-port, made of titanium, was implanted using local anesthesia in 11 patients (mean age 65 years, range 52-85 years) with biliary duct obstruction (7 malignant and 4 benign strictures). The subcutaneous part of the T-port consisted of a flange with several perforations allowing ingrowth of connective tissue. The T-port allowed catheter sizes of 10 and 12 Fr. Results. All wounds healed uneventfully and were followed by a stable period without signs of pronounced inflammation or infection. It was easy to open the port and to exchange the drainage tube. The patient's quality of life was considerably improved even though several patients had problems with repeated bile leakage due to frequent recurrent obstructions of the tubes. The ports were implanted for a mean time of 9 months (range 2-21 months). Histologic examination in four cases showed that the port was well integrated into the soft tissue. Tilting of the T-port in two cases led to perforation of the skin by the subcutaneous part of the ports, which were removed after 7 and 8 months. Conclusion. The T-port served as an excellent external access to the biliary ducts. The drainage tubes were well fixed within the ports. The quality of life of the patients was considerably improved. Together with improved aesthetic appearance they found it easier to conduct normal daily activities and personal care. However, the problem of recurrent catheter obstruction remained unsolved.

    Around the world, there is great concern about the movement of threat materials using seaport shipping containers. The benefits of early detection of weapons of mass destruction is obvious. However, the inspection process needs to be conducted in such a way as to not unreasonably impede normal commerce. Prior to actual deployment of new detection systems, policies, or procedures, it is useful to construct an operational and economic model of the port facility and to run simulations to gage the impact. Using a simulation model beforehand aids decision makers in evaluating trade-offs. PortSim was developed at ORNL by the author to allow a user to investigate a number of parameters in order to see the impact on port operations and cost. It consolidates a conceptual operations model, cost information, policy and procedures database, a real-time data acquisition capability, and information flow tracking and provides a visualization of port operations in a geospatial environment. This paper describes the use of PortSim to simulate and visualize a typical port.

    Abstract Introduction Dural port therapy (DPT) is a chiropractic procedure which can be used effectively with Sacro-Occipital Technique (SOT) procedures and which uses the sacrum as a lever to influence and balance the spine and cranium by way of the meningeal system. Discussion Rationale and research is presented to explain the basis behind DPT's method of affecting the craniospinal system and its relationship to the meninges. Though the procedure can be used with most conditions, DPT appears to be safe to use with osteoporotic conditions, fractured vertebrae, and other conditions where a “thrust” to the spine may be contraindicated. Basic methods of using DPT are presented along with alternative methods which can be applied when the basic methods are not sufficient. Conclusion DPT reduces sacral, spinal, and cranial dura meningeal tension, lesions, torque and stress, as well as dural sleeve vasomotor interference. The possibility that the doctor can influence the nervous system directly in such a powerful manner warrants further investigation. PMID:19674561

    1993-07-05

    The Port of Corpus Christi, Texas, with the support of several oil companies and the blessing of the US Coast Guard, plans to build a $600-million deepwater harbor to accommodate supertankers. The proposed port, Safeharbor, is touted as an environmentally sound solution to current risks associated with off-loading crude oil from very large tankers at shore ports. In a system called lightering, crude now is transferred from supertankers in deep water to smaller vessels that can negotiate shallow channels. While smaller tankers need only 45 ft of water, supertankers need 80 ft. Corpus Christi has the advantage of being closer to deep water than other Gulf ports, but nevertheless, half the proposed project's cost, $300 million, would be for dredging a 10-mile channel to deep water.

    2016-01-01

    Port development in Thailand is an essential part of the national maritime interest in connection with ship and shore activities. The growth of maritime industry and transportation has led to the expansion of ports' areas and capacity. Each port type causes different environmental impacts. Therefore, the Port Authority of Thailand has set up guidelines on ports' environmental management. This is divided into 3 major phases; namely, planning, construction and operation commencement periods. The Report of Environmental and Health Impact Assessment (EIA, HIA and EHIA) is regarded as the environmental management process in the planning period. It is a key tool to anticipate and prevent any adverse effects that might occur on the environment as well as community health resulting from the project implementation. This measure, in turn, creates advance preparation on both the preventive and problem-solving means before the project gets off the ground. At present, the majority of new projects on port development have still been in the process of information gathering for EHIA submission. Some cannot start to operate due to their EHIA failure. For example, the Tha-sala port which did not pass EHIA, mainly because emphasis had been focused on adhering to legal regulations without taking into consideration the in-depth analysis of data being conducted by community entities in the area. Thus caused the project to be finally abolished. Impact assessment on environment and health should be aimed at detailed understanding of the community in each particular area so that effective data of objective achievement in preventing environmental problems could actually be carried out and welcomed by the concerned society.

  5. Test Port for Fiber-Optic-Coupled Laser Altimeter

    2011-01-01

    A test port designed as part of a fiber optic coupled laser altimeter receiver optical system allows for the back-illumination of the optical system for alignment verification, as well as illumination of the detector(s) for testing the receiver electronics and signal-processing algorithms. Measuring the optical alignment of a laser altimeter instrument is difficult after the instrument is fully assembled. The addition of a test port in the receiver aft-optics allows for the back-illumination of the receiver system such that its focal setting and boresight alignment can be easily verified. For a multiple-detector receiver system, the addition of the aft-optics test port offers the added advantage of being able to simultaneously test all the detectors with different signals that simulate the expected operational conditions. On a laser altimeter instrument (see figure), the aft-optics couple the light from the receiver telescope to the receiver detector(s). Incorporating a beam splitter in the aft-optics design allows for the addition of a test port to back-illuminate the receiver telescope and/or detectors. The aft-optics layout resembles a T with the detector on one leg, the receiver telescope input port on the second leg, and the test port on the third leg. The use of a custom beam splitter with 99-percent reflection, 1-percent transmission, and a mirrored roof can send the test port light to the receiver telescope leg as well as the detector leg, without unduly sacrificing the signal from the receiver telescope to the detector. The ability to test the receiver system alignment, as well as multiple detectors with different signals without the need to disassemble the instrument or connect and reconnect components, is a great advantage to the aft-optics test port. Another benefit is that the receiver telescope aperture is fully back-illuminated by the test port so the receiver telescope focal setting vs. pressure and or temperature can be accurately measured (as

    Against a background of developing research on Red Sea ports, a hypothetical model of the morphology of port towns during the early Islamic period is presented here. These places went through constant cycles of change as economic and political frameworks fluctuated. While their physical shape and form was strongly influenced by architectural features of the Islamic world their functionality was more aligned to commercial interaction. These were dynamic spaces where the daily life of their inhabitants was guided by trade, religion, weather and politics. The ports were intrinsically tied to the trade networks that connected Africa with Arabia and the broader Indian Ocean world.

    1994-01-01

    Implantable injection port systems are safe and convenient for long-term venous access. The present investigation comprises nurses' and patients' evaluation of three different types of devices; Port-A-Cath (16.0 g), Cordis Miniport (3.8 g) for implantation in the chest wall and the PAS Port system (5.6 g) for implantation in the forearm. The devices were implanted for chemotherapy. Eighty patients and 17 nurses answered a questionnaire regarding their experience with the devices. Overall, the systems functioned well and were helpful for both patients and nurses. In the patient study few significant differences emerged. Nurses noted that the PAS Port system was more difficult to withdraw blood from (P < 0.001) and its infusion flow capacity was inferior to the two ports in the chest wall (P < 0.001). Port-A-Cath was judged to be the easiest system for needle insertion and the needle position was felt to be more secure (P < 0.001). Fourteen of the 17 nurses preferred Cordis Miniport for cosmetic reasons (P < 0.001). All devices functioned well. The differences in shape, size and site of implantation allow an optimum port selection for each patient. The replies in this study expressed the need for educational programmes in order to spread the injection port concept further. PMID:8138625

    Zhang, Min; Sihoe, Alan D. L.

    2016-01-01

    Background Single-port video-assisted thoracoscopic surgery (VATS) left upper lobectomy is difficult amongst all the lobes. At the beginning of single-port lobectomies, the upper lobes were believed not to be amenable for single-port approach due to the difficult angulation for staplers. Gonzalez reported the first single-port VATS left upper lobectomy in 2011. Methods We report a new technique of single-port VATS left upper lobectomy with the concept of “reverse direction”. We divide the apical-anterior arterial trunk with upper vein in the last. The procedure sequence is described as follows: posterior artery, lingular artery, bronchus and finally upper vein & apical-anterior arterial trunk. Results This method could overcome the angular limitations frequently encountered in single-port VATS procedures; reduce the risk of injuries to pulmonary artery; broaden the indications of single-port the upper lobe of the left lung (LUL) to include hypoplastic lung fissures. Limitations of this new practice include the enlargement or severe calcifications of hilar and bronchial lymph nodes. Conclusions A “reverse direction” technique of single-port left upper pulmonary resection is feasible and safe. PMID:27621885

    Introduction Traditionally, laparoscopic mesh rectopexy is performed with four ports, in an attempt to improve cosmetic results. Following laparoscopic mesh rectopexy there is a new operative technique called single-port laparoscopic mesh rectopexy. Aim To evaluate the single-port laparoscopic mesh rectopexy technique in control of rectal prolapse and the cosmesis and body image issues of this technique. Material and methods The study was conducted in El Fayoum University Hospital between July 2013 and November 2014 in elective surgery for symptomatic rectal prolapse with single-port laparoscopic mesh rectopexy on 10 patients. Results The study included 10 patients: 3 (30%) males and 7 (70%) females. Their ages ranged between 19 years and 60 years (mean: 40.3 ±6 years), and they all underwent laparoscopic mesh rectopexy. There were no conversions to open technique, nor injuries to the rectum or bowel, and there were no mortalities. Mean operative time was 120 min (range: 90–150 min), and mean hospital stay was 2 days (range: 1–3 days). Preoperatively, incontinence was seen in 5 (50%) patients and constipation in 4 (40%). Postoperatively, improvement in these symptoms was seen in 3 (60%) patients for incontinence and in 3 (75%) for constipation. Follow-up was done for 6 months and no recurrence was found with better cosmetic appearance for all patients. Conclusions Single-port laparoscopic mesh rectopexy is a safe procedure with good results as regards operative time, improvement in bowel function, morbidity, cost, and recurrence, and with better cosmetic appearance.

    A new diverless method for deep water laying and connecting a flowline bundle linking a production well to a subsea manifold has been developed. A specifically developed system was used and no flowline length adjustment was required ''in situ''. The flowline bundle assembly is fabricated and tested on-shore, before its launching and towing. After the first phase of towing, the bundle is submerged to 30 m. The bundle is then pulled near the sea-floor with the guide rope method to the site where two base structures with acoustic transponders have been installed. The bundle is positioned by an acoustic system. Two structures bearing a sheave for the pulling cables are lowered to the sea bottom and stabbed to the two bases respectively. All re-entries are performed by the acoustic guidelineless drilling method. Final direct or side pulling is done by winches and heave compensators on board a drilling vessel which is successively dynamically positioned on top of each base. The side pulling is monitored by an acoustic system. After pulling, each end of the bundle is latched to the structure. Using drill pipes the connecting modules are stabbed to the pulling structures, then a vertical connection to each end of the flowline is performed. (see fig. 1) A sea trial of this method was successfully performed in 250 meter water depth in the Mediterranean Sea in May 1981.

  4. Towards a better understanding on how large wood is controlling longitudinal sediment (dis)connectivity in mountain streams - concepts and first results

    Large wood (LW) provides various ecological and morphological functions. Recent research has focused on habitat diversity and abundance, effects on channel planforms, pool formation, flow regimes and increased storage of organic matter as well as storage of fine sediment. While LW studies and sediment transport rates are the focus of numerous research questions, the influence of large channel blocking barriers (e.g. LW) and their impact on sediment trapping and decoupling transportation pathways is less studied. This project tries to diminish the obvious gap and deals with the modifications of the sediment connectivity by LW. To investigate the influence of large wood on sediment transporting processes and sediment connectivity, the spatial distribution and characterization of LW (>1 m in length and >10 cm in diameter) in channels is examined by field mapping and dGPS measurements. Channel hydraulic parameters are determined by field measurements of channel long profiles and cross sections. To quantify the direct effects of LW on discharge and bed load transport the flow velocity and bed load up- and downstream of LW is measured using an Ott-Nautilus and a portable Helley-Smith bed load sampler during different water stages. Sediment storages behind LWD accumulations will be monitored with dGPS. While accumulation of sediment indicates in-channel sediment storage and thus disconnection from downstream bed load transport, erosion of sediment evidences downstream sediment connectivity. First results will be presented from two study areas in mountain ranges in Germany (Wetterstein Mountain Range) and Austria (Bohemian Massif).

    Subsurface fluid flow is strongly influenced by faults and fractures, yet the transmissivity of faults and fractures changes through time due to deformation and cement precipitation, making flow paths difficult to predict. Here we assess past fracture connectivity in an active hydrothermal system in the Basin and Range, Nevada, USA, using clumped isotope geochemistry and cold cathodoluminescence (CL) analysis of fracture filling cements from the Blue Mountain geothermal field. Calcite cements were sampled from drill cuttings and two cores at varying distances from faults. CL microscopy of some of the cements shows banding parallel to the fracture walls as well as brecciation, indicating that the cements record variations in the composition and source of fluids that moved through the fractures as they opened episodically. CL microscopy, δ13C and δ18O values were used to screen homogeneous samples for clumped isotope analysis. Clumped isotope thermometry of most samples indicates paleofluid temperatures of around 150°C, with several wells peaking at above 200°C. We suggest that the consistency of these temperatures is related to upwelling of fluids in the convective hydrothermal system, and interpret the similarity of the clumped isotope temperatures to modern geothermal fluid temperatures of ~160-180°C as evidence that average reservoir temperatures have changed little since precipitation of the calcite cements. In contrast, two samples, one of which was associated with fault gauge observed in drill logs, record significantly cooler temperatures of 19 and 73°C and anomalous δ13C and δ18Owater values, which point to fault-controlled pathways for downwelling meteoric fluid. Finally, we interpret correspondence of paleofluid temperatures and δ18Owater values constrained by clumped isotope thermometry of calcite from different wells to suggest past connectivity of fractures among wells within the geothermal field. Results show the ability of clumped isotope

    An intermediate hub might increase the accessibility level of ports but also hinterland and so it can be considered more than a facility with a transhipment role. These hubs might lead to the development of other transport services and enhance their role in gathering and covering economic centres within hinterlands and also getting the part of logistic facility for the ports, with effects on port utilization and its connectivity to global economy. A new location for a hub terminal leads to reduced transport distances within hinterland, with decreased transport costs and external effects, so with gains in people's life quality. Because the production and distribution systems are relatively fixed on short and medium term and the location decisions are strategic and on long term, the logistic chains activities location models have to consider the uncertainties regarding the possible future situations. In most models, production costs are considered equal, the location problem reducing itself to a problem that aims to minimize the total transport costs, meaning the transport problem. The main objective of the paper is to locate a hub terminal that links the producers of cereals that are going to be exported by naval transportation with the Romanian fluvial-maritime ports (Galaţi, Brăila). GIS environment can be used to integrate and analyse a great amount of data and has the ability of using functions as location - allocation models necessary both to private and public sector, being able to determine the optimal location for services like factories, warehouses, logistic platforms and other public services.

    This document contains the results of an optical design scoping study of visible-light and infrared optics for the ITER upper ports, performed by LLNL under contract for the US ITER Project Office. ITER is an international collaboration to build a large fusion energy tokamak with a goal of demonstrating net fusion power for pulses much longer than the energy confinement time. At the time of this report, six of the ITER upper ports are planned to each to contain a camera system for recording visible and infrared light, as well as other diagnostics. the performance specifications for the temporal and spatial resolution of this system are shown in the Section II, Functional Specifications. They acknowledge a debt to Y. Corre and co-authors of the CEA Cadarache report ''ITER wide-angle viewing and thermographic and visible system''. Several of the concepts used in this design are derived from that CEA report. The infrared spatial resolution for optics of this design is diffraction-limited by the size of the entrance aperture, at lower resolution than listed in the ITER diagnostic specifications. The size of the entrance aperture is a trade-off between spatial resolution, optics size in the port, and the location of relay optics. The signal-to-noise ratio allows operation at the specified time resolutions.

    Single port video-assisted thoracic surgery (VATS) is the most recent evolution in minimally invasive thoracic surgery. With increasing global popularity, the single port VATS approach has been adopted by experienced thoracic surgeons in many Asian countries. From initial experience of single port VATS lobectomy to the more complex sleeve resection procedures now forming part of daily practice in some Asia institutes, the region has been the proving ground for single port VATS approaches' feasibility and safety. In addition, certain technical refinements in single port VATS lung resection and lymph node dissection have also sprung from Asia. Novel equipment designed to facilitate single port VATS allowing further reduce access trauma are being realized by the partnership between surgeons and the industries. Advanced thoracoscopes and staplers that are narrower and more maneuverable are particularly important in the smaller habitus of patients from Asia. These and similar new generation equipment are being applied to single port VATS in novel ways. As dedicated thoracic surgeons in the region continue to striving for excellence, innovative ideas in single incision access including subxiphoid and embryonic natural-orifice transluminal endoscopic surgery (e-NOTES) have been explored. Adjunct techniques and technology used in association with single port VATS such as non-intubated surgery, hybrid operating room image guidance and electromagnetic navigational bronchoscopy are all in rapid development in Asia.

    Improved technology for the efficient transfer of cryogens is needed for future on-orbit fueling and remote Lunar/Mars operations. The cooling and filling of a liquid nitrogen (LN2) test vessel through a single port were investigated in a series of experiments. A new 'in-space' transfer tube design concept was used to demonstrate the ability to quickly cool and load cryogens through a single feed-through connection. Three different fill tube configurations with three different diameters were tested. The tubes providing the quickest cooldown time and the quickest fill time for the test article tank were determined. The results demonstrated a clear trade-off between cooling time and filling time for the optimum tube design. This experimental study is intended to improve technology for future flight tank designs by reducing fill system size, complexity, heat leak rate, and operations time. These results may be applied to Space Shuttle Power Reactant Storage and Distribution (PRSD) System upgrades and other future applications. Further study and experimental analysis for optimization of the fill tube design are in progress.

    Objective This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. Methods Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. Results There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. Conclusion Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery. PMID:25264528

    1993-05-01

    The Waste Receiving and Processing Module I (WRAP-1) facility must have the ability to allow 55-gallon drums to enter and exit glovebox enclosures. An Entry/Exit Port (Appendix 1, Figure 1), designed by United Engineers and Constructors (UE&C), is one method chosen for drum transfer. The Entry/Exit Port is to be used for entry of 55-gallon drums into both process entry gloveboxes, exit of 55-gallon drum waste pucks from the low-level waste (LLW) glovebox, and loadout of waste from the restricted waste management glovebox. The Entry/Exit Port relies on capture velocity air flow and a neoprene seal to provide alpha confinement when the Port is in the open and closed positions, respectively. Since the glovebox is in a slight vacuum, air flow is directed into the glovebox through the space between the overpack drum and glovebox floor. The air flow is to direct any airborne contamination into the glovebox. A neoprene seal is used to seal the Port door to the glovebox floor, thus maintaining confinement in the closed position. Entry/Exit Port testing took place February 17, 1993, through April 14, 1993, in the 305 building of Westinghouse Hanford Company. Testing was performed in accordance with the Entry/Exit Port Testing Test Plan, document number WHC-SD-WO26-TP-005. A prototype Entry/Exit Port built at the Hanford Site was tested using fluorescent paint pigment and smoke candles as simulant contaminants. This test report is an interim test report. Further developmental testing is required to test modifications made to the Port as the original design of the Port did not provide complete confinement during all stages of operation.

    1994-01-01

    A concept for placing a pressure transducer directly in a shuttle type tile was developed at Langley Research Center. A 5 inch long quartz with a .020 inch inner diameter provides the thermal isolation necessary to allow 2800 F surface pressure measurements to be taken by pressure transducer rated at 250 F. The assembly is potted in place with RTV 560 in a piece of FRCI-12 thermal protection system insulation tile. The integrity of the thermal protection system is maintained even with the intrusion of the pressure port assembly and the pressure port does not disrupt the air flow across the lifting body. Approximately 200 of these pressure ports are to be used in each of the Hypersonic Flight Experiment (HYFLITE) flight tests. Initial vibroacoustic and aerothermal testing of the pressure port designs have been completed at Langley Research vibration laboratory and the 20 MWatt 2 x 9 turbulent duct facility at Ames Research Center. The performance of the pressure ports were found to be well within the required design limits for all cases. In addition, a failure mode in which the entire pressure port assembly was removed proved to be a begin case.

    AIM: To apply the laparoscopic and endoscopic cooperative surgery concept, we investigated whether endoscopic cholecystectomy could be performed more safely and rapidly via only 1 port or not. METHODS: Two dogs (11 and 13-mo-old female Beagle) were used in this study. Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed. After complete resection of the gallbladder bed, the gallbladder was pulled up to resect its neck using the Ring-shaped thread technique. The neck of the gallbladder was cut using scissor forceps. Resected gallbladder was retrieved using endoscopic net forceps via a port. RESULTS: The operation times from general anesthetizing with sevoflurane to finishing the closure of the blunt port site were about 50 min and 60 min respectively. The resection times of gallbladder bed were about 15 min and 13 min respectively without liver injury and bleeding at all. Feed were given just after next day of operation, and they had a good appetite. Two dogs are in good health now and no complications for 1 mo after endoscopic cholecystectomy using only a flexible endoscope via one port. CONCLUSION: We are sure of great feasibility of endoscopic cholecystectomy via single port for human. PMID:27053847

    Background Low level connective tissue inflammation has been proposed to play a role in thyroid associated ophthalmopathy (TAO). The aim of this study was to investigate this postulate by a musculoskeletal approach together with biochemical parameters. Methods 13 patients with TAO and 16 controls were examined. Erythrocyte levels of Zn, Cu, Ca2+, Mg, and Fe were determined. The musculoskeletal evaluation included observational data on body posture with emphasis on the orbit-head region. The angular foot position in the frontal plane was quantified following gait observation. The axial orientation of the legs and feet was evaluated in an unloaded supine position. Functional propioceptive tests based on stretch stimuli were done by using foot inversion and foot rotation. Results Alterations in the control group included neck tilt in 3 cases, asymmetrical foot angle during gait in 2, and a reaction to foot inversion in 5 cases. TAO patients presented facial asymmetry with displaced eye fissure inclination (mean 9.1°) as well as tilted head-on-neck position (mean 5.7°). A further asymmetry feature was external rotation of the legs and feet (mean 27°). Both foot inversion as well as foot rotation induced a condition of neuromuscular deficit. This condition could be regulated by gentle acupressure either on the lateral abdomen or the lateral ankle at the acupuncture points gall bladder 26 or bladder 62, respectively. In 5 patients, foot rotation produced a phenomenon of moving toes in the contra lateral foot. In addition foot rotation was accompanied by an audible tendon snapping. Lower erythrocyte Zn levels and altered correlations between Ca2+, Mg, and Fe were found in TAO. Conclusion This whole body observational study has revealed axial deviations and body asymmetry as well as the phenomenon of moving toes in TAO. The most common finding was an arch-like displacement of the body, i.e. eccentric position, with foot inversion and head tilt to the contra lateral side

  6. Free-space optical mesh-connected bus networks using wavelength-division multiple access.

    PubMed

    Li, Y; Lohmann, A W; Rao, S B

    1993-11-10

    A novel optical free-space mesh-connected bus interconnect network architecture is proposed. A mesh-connected bus [IEEE Trans. Comput. C-30, 264-273 (1981)] is known to have the capability of interconnecting, with a three-stage switching, N nodes with a power distribution loss proportional to √N and is therefore advantageous for networking a large number, say over 1000, of communicating ports. Based on conventional space-invariant optical components in a compact and efficient geometry, the proposed optical mesh-connected bus system concept can be used to build either free-space optical interconnect links for parallel processing applications or central switching systems for local or global lightwave communication networks. The proposed architecture lends itself to networking under both the wavelength-division multiple access and other multiple-access environments. In this paper, based on the wavelength-division multiple-access environment, various optical system implementation and performance issues are discused and parameters are analyzed. It was found that by use of a reasonably compact three-dimensional free-space volume, more than 100,000 dispersion-limited communication nodes at a uniform channel spacing of 0.75 nm can be linked with a moderate power distribution loss of 28 dB. Some preliminary optical wavelength-division multiple-access mesh-connected bus experiments based on a 27 × 27 panchromatic optical source array were performed to confirm the operational principle of the proposed concept.

  8. Porting Social Media Contributions with SIOC

    NASA Astrophysics Data System (ADS)

    Bojars, Uldis; Breslin, John G.; Decker, Stefan

    Social media sites, including social networking sites, have captured the attention of millions of users as well as billions of dollars in investment and acquisition. To better enable a user's access to multiple sites, portability between social media sites is required in terms of both (1) the personal profiles and friend networks and (2) a user's content objects expressed on each site. This requires representation mechanisms to interconnect both people and objects on the Web in an interoperable, extensible way. The Semantic Web provides the required representation mechanisms for portability between social media sites: it links people and objects to record and represent the heterogeneous ties that bind each to the other. The FOAF (Friend-of-a-Friend) initiative provides a solution to the first requirement, and this paper discusses how the SIOC (Semantically-Interlinked Online Communities) project can address the latter. By using agreed-upon Semantic Web formats like FOAF and SIOC to describe people, content objects, and the connections that bind them together, social media sites can interoperate and provide portable data by appealing to some common semantics. In this paper, we will discuss the application of Semantic Web technology to enhance current social media sites with semantics and to address issues with portability between social media sites. It has been shown that social media sites can serve as rich data sources for SIOC-based applications such as the SIOC Browser, but in the other direction, we will now show how SIOC data can be used to represent and port the diverse social media contributions (SMCs) made by users on heterogeneous sites.

    2016-04-01

    > In the single fluid, non-relativistic, ideal magnetohydrodynamic (MHD) plasma description, magnetic field lines play a fundamental role by defining dynamically preserved `magnetic connections' between plasma elements. Here we show how the concept of magnetic connection needs to be generalized in the case of a relativistic MHD description where we require covariance under arbitrary Lorentz transformations. This is performed by defining 2-D magnetic connection hypersurfaces in the 4-D Minkowski space. This generalization accounts for the loss of simultaneity between spatially separated events in different frames and is expected to provide a powerful insight into the 4-D geometry of electromagnetic fields when .

  11. Multi-port valve assembly

    DOEpatents

    Guggenheim, S. Frederic

    1986-01-01

    A multi-port fluid valve apparatus is used to control the flow of fluids through a plurality of valves and includes a web, which preferably is a stainless steel endless belt. The belt has an aperture therethrough and is progressed, under motor drive and control, so that its aperture is moved from one valve mechanism to another. Each of the valve mechanisms comprises a pair of valve blocks which are held in fluid-tight relationship against the belt. Each valve block consists of a block having a bore through which the fluid flows, a first seal surrounding the bore and a second seal surrounding the first seal, with the distance between the first and second seals being greater than the size of the belt aperture. In order to open a valve, the motor progresses the belt aperture to where it is aligned with the two bores of a pair of valve blocks, such alignment permitting a flow of the fluid through the valve. The valve is closed by movement of the belt aperture and its replacement, within the pair of valve blocks, by a solid portion of the belt.

  11. Single-port video-assisted thoracoscopic surgery for lung cancer

    PubMed Central

    Liu, Chao-Yu; Lin, Chen-Sung; Shih, Chih-Hsun

    2014-01-01

    In 2004, novel results using pulmonary wedge resection executed through single-port video-assisted thoracoscopic surgery (VATS) was first described. Since that time, single-port VATS has been advocated for the treatment of a spectrum of thoracic diseases, especially lung cancer. Lung cancer remains one of the top three cancer-related deaths in Taiwan, and surgical resection remains the “gold standard” for early-stage lung cancer. Anatomical resections (including pneumonectomy, lobectomy, and segmentectomy) remain the primary types of lung cancer surgery, regardless of whether conventional open thoracotomy, or 4/3/2-ports VATS are used. In the past three years, several pioneers have reported their early experiences with single-port VATS lobectomy, segmentectomy, and pneumonectomy for lung cancer. Our goal was to appraise their findings and review the role of single-port VATS in the treatment of lung cancer. In addition, the current concept of mini-invasive surgery involves not only smaller resections (requiring only a few incisions), but also sub-lobar resection as segmentectomy. Therefore, our review will also address these issues. PMID:24455171

    2001-08-01

    Since the early development of the penta-prism long trace profiler (LTP) and the in situ LTP, and following the completion of the first in situ distortion profile measurements at Sincrotrone Trieste (ELETTRA) in Italy in 1995, a concept was developed for a compact, portable LTP with the following characteristics: easily installed on synchrotron radiation beam lines, easily carried to different laboratories around the world for measurements and calibration, convenient for use in evaluating the LTP as an in-process tool in the optical workshop, and convenient for use in temporarily installation as required by other special applications. The initial design of a compact LTP optical head was made at ELETTRA in 1995. Since 1997 further efforts to reduce the optical head size and weight, and to improve measurement stability have been made at Brookhaven National Laboratory. This article introduces the following solutions and accomplishments for the portable LTP: (1) a new design for a compact and very stable optical head, (2) the use of a small detector connected to a laptop computer directly via an enhanced parallel port, and there is no extra frame grabber interface and control box, (3) a customized small mechanical slide that uses a compact motor with a connector-sized motor controller, and (4) the use of a laptop computer system. These solutions make the portable LTP able to be packed into two laptop-size cases: one for the computer and one for the rest of the system.

    1999-07-08

    With the advent of networked computer systems that connect disparate computer hardware and operating systems, it is important for port simulation systems to be able to run on a wide variety of computer platforms. This paper describes the design and implementation issues in reengineering the PORTSIM model in order to field the model to Windows-based systems as well as to Unix-based systems such as the Sun, Silicon Graphics, and HP workstations. The existing PORTSIM model was written to run on a Sun workstation running Unix. The model was initially implemented in MODSIM and C and utilized embedded SQL to retrieve port, ship, and cargo data from back-end OMCLE databases. Output reports, graphs, and tables for model results were written in C, utilizing third-party graphics libraries. This design and implementation worked well for the intended hardware platform and configuration, but as the number of model users grew and as the capabilities of the model expanded, a need developed to field the model to varying hardware configurations. This new requirement demanded that the existing design be modified to more easily allow for model fielding and maintenance. A phased approach is described that (1) identifies the existing model from which cross-platform development began, (2) delineates an intermediate client-server model that has been developed utilizing Java to allow for greater flexibility and ease in distributing and fielding the model, and (3) describes the final goals to be achieved in this development process.

    The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the thin-walled behaviour. This paper aims to review current researches on cold-formed steel connections, particularly for screw connections, storage rack connections, welded connections, and bolted connections. The performance of these connections in the design of cold-formed steel structures is discussed. PMID:24688448

    2016-01-01

    The single port laparoscopic method was first used in 1999 by Bresadola for cholecystectomy. Nearly a decade later, in 2008, the first single port right hemicolectomy was reported by Bucher and others in a case involving an ascending colon polyp (1,2). The continuous technological evolutional lows the first single port right hemicolectomy 17 years after the first laparoscopic hemicolectomy (1991) which was initially met with reluctance and after has gained a well-established place in the range of colorectal surgery (2). Single port access, as well as NOTES, provides, in comparison with the standard laparoscopic procedure, the aesthetic benefit, the decrease of postoperative pain and a shorter duration of hospitalization, while in terms of disadvantages, we could mention a longer surgery duration due to fewer opportunities of triangulation and vision (3,4). The reduction of postoperative pain plus the good aesthetic results with no significant increase of postoperative complications, already proved by retrospective studies, require confirmation by randomized studies envisaged by trial TRUE in France (5). Single port right hemicolectomy can be achieved with oncologic results similar to standard laparoscopic surgery, having very good postoperative results in terms of aesthetics and reduced postoperative pain (5,6,7).

    Background To summarize our experiences of single-port, two-port vs. three-port VATS pulmonary resection for lung cancer patients. Methods Data of consecutive 1,553 patients who underwent video assisted thoracoscopic surgery (VATS) pulmonary resection for lung cancer in the Department of Thoracic Surgery of Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College between November 2014 and January 2016 were prospectively collected and analyzed. A propensity-matched analysis was used to compare the short-term outcomes of lung cancer patients who received VATS single-port, two-port and three-port pulmonary resection. Results There were 716 males and 837 females. The mean age was 58.90 years (range, 25–82 years) and the conversion rate was 2.7% (42/1,553) in this cohort. After propensity score matching, there were 207 patients in single-port and two-port group, and 680 patients in three-port group. Propensity-matched analysis demonstrated that there were no significant differences in duration of operation (129 vs. 131 min, P=0.689), intra-operative blood loss (63 vs. 70 mL, P=0.175), number of dissected lymph nodes (12 vs. 13, P=0.074), total hospital expense (﹩9,928 vs. ﹩9,956, P=0.884) and cost of operation (﹩536 vs. ﹩535, P=0.879) between VATS single-port, two-port and conventional three-port pulmonary resection groups. There was no significant difference in the complication rate between two groups (5.3% vs. 4.7%, P=0.220). However, compared with three-port group, patients who underwent single port and two-port experienced shorter postoperative length of stay (6.24 vs. 5.61 d, P=0.033), shorter duration of chest tube (4.92 vs. 4.25 d, P=0.008), and decreased volume of drainage (926 vs. 791 d, P=0.003). Conclusions The short term outcomes between VATS single-port, two-port and conventional three-port groups for the surgical treatment of lung cancer were comparable. However, compared with three-port VATS pulmonary resection

  20. ASRM Multi-Port Igniter Flow Field Analysis

    NASA Technical Reports Server (NTRS)

    Kania, Lee; Dumas, Catherine; Doran, Denise

    1993-01-01

    The Advanced Solid Rocket Motor (ASRM) program was initiated by NASA in response to the need for a new generation rocket motor capable of providing increased thrust levels over the existing Redesigned Solid Rocket Motor (RSRM) and thus augment the lifting capacity of the space shuttle orbiter. To achieve these higher thrust levels and improve motor reliability, advanced motor design concepts were employed. In the head end of the motor, for instance, the propellent cast has been changed from the conventional annular configuration to a 'multi-slot' configuration in order to increase the burn surface area and guarantee rapid motor ignition. In addition, the igniter itself has been redesigned and currently features 12 exhaust ports in order to channel hot igniter combustion gases into the circumferential propellent slots. Due to the close proximity of the igniter ports to the propellent surfaces, new concerns over possible propellent deformation and erosive burning have arisen. The following documents the effort undertaken using computational fluid dynamics to perform a flow field analysis in the top end of the ASRM motor to determine flow field properties necessary to permit a subsequent propellent fin deformation analysis due to pressure loading and an assessment of the extent of erosive burning.

Significant problems encountered along the way are listed along with an estimation of the overall cost of the port. This report may serve as a baseline for streamlining further porting activities with other ASC codes.

  2. Laser treatment of port-wine stains

    PubMed Central

    Brightman, Lori A; Geronemus, Roy G; Reddy, Kavitha K

    2015-01-01

    Port-wine stains are a type of capillary malformation affecting 0.3% to 0.5% of the population. Port-wine stains present at birth as pink to erythematous patches on the skin and/or mucosa. Without treatment, the patches typically darken with age and may eventually develop nodular thickening or associated pyogenic granuloma. Laser and light treatments provide improvement through selective destruction of vasculature. A variety of vascular-selective lasers may be employed, with the pulsed dye laser being the most common and well studied. Early treatment produces more optimal results. Advances in imaging and laser treatment technologies demonstrate potential to further improve clinical outcomes. PMID:25624768

  9. Connected Knowledge in Science and Mathematics Education

    NASA Astrophysics Data System (ADS)

    Zohar, Anat

    2006-10-01

    While the traditional meaning of connected knowledge is valuable in some school subjects, it does not address the main activities of knowledge acquisition in subjects such as physics and mathematics. The goal of this article is to analyze the relationships between the concepts “learning for understanding” and “connected knowledge”, a central theme in feminist epistemology. In learning for understanding, the learner forms multiple, intricate connections among the concepts she is studying in school, between school concepts and her everyday concepts, and between school concepts and their wider context. Viewing connected knowledge as tightly related to understanding has several important implications. It brings connected knowledge into the central learning activities that take place in school science and mathematics, and gives it a high status. It contributes to our understanding of gender-related patterns in thinking; and it may form a unifying theoretical framework for many studies and projects in the field of gender fair education.

  19. Generalized magnetofluid connections in relativistic magnetohydrodynamics.

    PubMed

    Asenjo, Felipe A; Comisso, Luca

    2015-03-20

    The concept of magnetic connections is extended to nonideal relativistic magnetohydrodynamical plasmas. Adopting a general set of equations for relativistic magnetohydrodynamics including thermal-inertial, thermal electromotive, Hall, and current-inertia effects, we derive a new covariant connection equation showing the existence of generalized magnetofluid connections that are preserved during the dissipationless plasma dynamics. These connections are intimately linked to a general antisymmetric tensor that unifies the electromagnetic and fluid fields, allowing the extension of the magnetic connection notion to a much broader concept.

    1993-12-01

    We developed a pulmonary artery (PA) double port catheter technique for reliable clinical measurements of pulmonary capillary pressure (Ppc). In seven elective surgical patients, the PA double port catheter with the second PA port 1 cm proximal to the balloon was inserted. The two PA ports, connected to identical pressure measuring systems, provided the pulmonary arterial pressures (Ppa) distal and proximal to the balloon. After general anesthesia was stabilized, the two Ppas were measured simultaneously during a PA occlusion maneuver during 10 s of apnea. The instant of occlusion was determined precisely as the time when the two Ppa traces sharply diverged. A single exponential equation was fitted to the segment of distal Ppa tracing starting 0.3 s after the instant of occlusion. Ppc was determined as the value of the exponential fit extrapolated to time 0. In six of seven patients, PA occlusion occurred consistently in the early systolic phase regardless of the timing of balloon inflation. Mean Ppa, Ppc, and pulmonary arterial wedge pressure were 16.6, 11.8, and 7.6 torr. The ratio of venous to total resistance ranged from 0.37 to 0.54 (mean:0.46). We conclude that this technique is clinically feasible and valuable in precise definition of the instant of PA occlusion. By defining PA occlusion consistently, this technique can provide reliable Ppc estimation in the clinical settings. PMID:8250302

  1. Complications Encountered with a Transfemorally Placed Port-Catheter System for Hepatic Artery Chemotherapy Infusion

    2001-03-15

    A port-catheter system was implanted via femoral artery access for hepatic artery chemotherapy infusion. Implantation was attempted in 90 patients and was successful in 88. Blood flow redistribution was performed using embolization coils. In the first ten patients a soft heparin-coated infusion catheter was used. For the following 78 patients we used a stiffer catheter coated with fluorine-acryl-styrene-urethane-silicone (FASUS) copolymer. The catheter was connected to a port implanted subcutaneously below the level of the inguinal ligament. Complications during the procedure and after placement were observed in 7 of 90 patients and 24 of 88 patients, respectively. These included catheter obstruction (11%), dislocation of the catheter tip (10%), drug toxicity (5.7%), and catheter infection (3.4%). In 6 of 10 patients with catheter obstruction, recanalization of the port system was achieved. In 7 of 9 patients with dislocation of the indwelling catheter tip, replacement of the port system was successful. Our complications appear to be comparable with those encountered with the subclavian/brachial approach when the new catheter coating is used. Notable is the avoidance of cerebral infarcts.

  2. An ultra-high vacuum chamber for scattering experiments featuring in-vacuum continuous in-plane variation of the angle between entrance and exit vacuum ports

    2015-09-15

    A concept that enables in-vacuum continuous variation of the angle between two ports in one plane has been developed and implemented. The vacuum chamber allows for measuring scattering cross sections as a function of scattering angle and is intended for resonant inelastic X-ray scattering experiments. The angle between the ports can be varied in the range of 30°-150°, while the pressure change is less than 2 × 10{sup −10} mbars.

  3. Optimum connection management scheduling

    NASA Astrophysics Data System (ADS)

    Kadar, Ivan

    2000-08-01

    Connection Management plays a key role in both distributed 'local' network-centric and 'globally' connected info- centric systems. The role of Connection Management is to provide seamless demand-based sharing of the information products. For optimum distributed information fusion performance, these systems must minimize communications delays and maximize message throughput, and at the same time take into account relative-sensors-targets geometrical constraints and data pedigree. In order to achieve overall distributed 'network' effectiveness, these systems must be adaptive, and be able to distribute data s needed in real- time. A system concept will be described which provides optimum capacity-based information scheduling. A specific example, based on a satellite channel, is used to illustrate simulated performance results and their effects on fusion systems performance.

  6. Governance and management of a deepwater port: a case study

    SciTech Connect

    Olcott, E.S.

    1985-10-01

    A deepwater port is many things to many people. Clearly, the Port of Rotterdam, the largest port in the world, is a deepwater port with its 75 feet of water, more than $1.5 billion invested in facilities and its annual volume of more than 280 million metric tons of cargo in a broad commodity mix. Bantry Bay in Ireland, a major import petroleum and trans-shipment facility for Britain and the European continent, is a deepwater port. So also is the Louisiana Offshore Oil Port (LOOP), comprised of a single-point mooring buoy and sophisticated petroleum distribution system, located in deep water off the Gulf coast of the US. And so is the Port of Seattle a deepwater port, located in the natural deep water of Puget Sound. Deep drafts ports abound in Japan where as many as nine ports have been developed with water depths in excess of 55 feet. The multi-purpose port and industrial island located in Delaware Bay, the case study being scrutinized in this article would also be a deepwater port. The author takes no position in this article on the feasibility of the enterprise. A number of models or options are reviewed on how this project might be organized, managed, and governed if a decision were made to move forward with such an undertaking. 15 references, 2 figures.

  9. About connections.

    PubMed

    Rockland, Kathleen S

    2015-01-01

    Despite the attention attracted by "connectomics", one can lose sight of the very real questions concerning "What are connections?" In the neuroimaging community, "structural" connectivity is ground truth and underlying constraint on "functional" or "effective" connectivity. It is referenced to underlying anatomy; but, as increasingly remarked, there is a large gap between the wealth of human brain mapping and the relatively scant data on actual anatomical connectivity. Moreover, connections have typically been discussed as "pairwise", point x projecting to point y (or: to points y and z), or more recently, in graph theoretical terms, as "nodes" or regions and the interconnecting "edges". This is a convenient shorthand, but tends not to capture the richness and nuance of basic anatomical properties as identified in the classic tradition of tracer studies.

  14. Low Back Pain in Port Machinery Operators

    NASA Astrophysics Data System (ADS)

    BOVENZI, M.; PINTO, I.; STACCHINI, N.

    2002-05-01

    The occurrence of several types of low back pain (LBP) was investigated by a standardized questionnaire in a group of 219 port machinery operators exposed to whole-body vibration (WBV) and postural load and in a control group of 85 maintenance workers employed at the same transport company. The group of port machinery operators included 85 straddle carrier drivers, 88 fork-lift truck drivers, and 46 crane operators. The vector sum of the frequency-weighted r.m.s. acceleration of vibration measured on the seatpan of port vehicles and machines averaged 0·90 m/s2 for fork-lift trucks, 0·48 m/s2 for straddle carriers, 0·53 m/s2 for mobile cranes, and 0·22 m/s2 for overhead cranes. The 12-month prevalence of low back symptoms (LBP, sciatic pain, treated LBP, sick leave due to LBP) was significantly greater in the fork-lift truck drivers than in the controls and the other two groups of port machinery operators. After adjusting for potential confounders, the prevalence of low back symptoms was found to increase with the increase of WBV exposure expressed as duration of exposure (driving years), equivalent vibration magnitude (m/s2), or cumulative vibration exposure (yr m2/s4). An excess risk for lumbar disc herniation was observed in the port machinery operators with prolonged driving experience. In both the controls and the port machinery operators, low back complaints were strongly associated with perceived postural load assessed in terms of frequency and/or duration of awkward postures at work. Multivariate analysis showed that vibration exposure and postural load were independent predictors of LBP. Even though the cross-sectional design of the present study does not permit firm conclusions on the relationship between WBV exposure and low back disorders, the findings of this investigation provide additional epidemiological evidence that seated WBV exposure combined with non-neutral trunk postures, as while driving, is associated with an increased risk of long

    Adding similar features and bug fixes often requires porting program patches from reference implementations and adapting them to target implementations. Porting errors may result from faulty adaptations or inconsistent updates. This paper investigates (I) the types of porting errors found in practice, and (2) how to detect and characterize potential porting errors. Analyzing version histories, we define five categories of porting errors, including incorrect control- and data-flow, code redundancy, inconsistent identifier renamings, etc. Leveraging this categorization, we design a static control- and data-dependence analysis technique, SPA, to detect and characterize porting inconsistencies. Our evaluation on code from four open-source projects shows thai SPA can dell-oct porting inconsistencies with 65% to 73% precision and 90% recall, and identify inconsistency types with 58% to 63% precision and 92% to 100% recall. In a comparison with two existing error detection tools, SPA improves precision by 14 to 17 percentage points

    An investigation was made with a specially designed engine to determine the scavenging characteristics of a large number of inlet-port shapes and arrangements and the optimum port arrangement and timing for this particular type of engine. A special cylinder construction permitted wide variations in timing for this particular type of engine. A special cylinder construction permitted wide variations in timing as well as in shape and arrangement of both the inlet and exhaust ports. The study of the effect of port shape combinations and timings on engine performance was made using illuminating gas as a fuel. Through variations in inlet-port arrangement and port timings, the value of the scavenging efficiency was increased from an original 44 percent to approximately 67 percent with a corresponding increase in power. With the optimum port arrangement and timing determined, a large number of performance runs were made under both spark-ignition and compression-ignition operation.

    2016-01-01

    Nowadays, the trend is to perform surgeries with “scarless” incisions. In light of this, the single-port laparoscopic surgery (SPLS) technique is rapidly becoming widespread due to its lack of invasiveness and its cosmetic advantages, as the only entry point is usually hidden in the umbilicus. The interest in “scarless” liver resections did not grow as rapidly as the interest in other scarless surgeries. Hepatopancreatobiliary surgeons are reluctant to operate a malignant lesion through a narrow incision with limited exposure. There are concerns over adverse oncological outcomes for single-port laparoscopic liver resections (SPL-LR) for hepatocellular carcinoma or metastatic colorectal cancer. In addition, getting familiar with using the operating instruments through a narrow incision with limited exposure is very challenging. In this article, we reviewed the published literature to describe history, indications, contraindications, ideal patients for new beginners, technical difficulty, advantages, disadvantages, oncological concern and the future of SPL-LR.

    The tsunamis that have occurred in many places around the world over the past decade have taken a heavy toll on human lives and property. The eastern coast of the Korean Peninsula is not safe from tsunamis, particularly the eastern coastal areas, which have long sustained tsunami damage. The aim of this study was to mitigate the casualties and property damage on the east eastern coast by developing a proper tsunami response system for important ports and harbors with high population densities and high concentrations of key national industries. For study purposes, the government-managed major international trade ports and coastal harbors were selected and an effective tsunami response system was formulated based on field surveys and related literature.

  1. Multi-port power electronic interface for renewable energy sources

    NASA Astrophysics Data System (ADS)

    Jiang, Wei

    Energy intensive products and services are penetrating people's daily life as well as different sectors of industry during recent decades. Further effort to improve efficiency, reduce green house gas and hazardous particle emission lead to the emergence of the "more electric" concept in several industries including transportation. This trend, however, burdens the aging power system and existing local power networks. To offer a remedy to the problem and a smooth transition to a more reliable, more diverse, and more efficient power grid of the future, the concept of Multi-port Power Electronic Interface (MPEI) for localized power processing is introduced in this dissertation, which interfaces and manages various sources, loads and storages. Different means of integrating multiple sources and storages into the existing power system are studied and evaluated; the six phase-leg structure is chosen to interface five sources/loads: fuel cell, wind turbine, solar cell, battery and utility grid. Partitioning of source-interface and load-interface on a system level as well as analysis and modeling on small signal level are performed. A novel control structure for source-interface is proposed in the design, which forms Controlled Quasi Current Source (CQCS) during the load sharing operation and offers several salient advantages: • Inherent average current-mode control. • Easy share of steady state current/power. • Share of load dynamics for better source protection. Local control loops for various input ports are designed based on linearized system model; controller performance is tuned to accommodate the characteristics of different sources. To maintain a sustainable operation, different modes of operation are defined for MPEI; detailed state-transition with associated events are also defined in each operation mode. Prototype of MPEI is built and control system is implemented digitally in a digital signal processor; steady state and transient performance of MPEI is

    Port wine stain (PWS), also called nevus flammeus, is a congenital, cutaneous vascular malformation involving post-capillary venules which produce a light pink to red to dark-red-violet discoloration of human skin [1]. PWS occurs in an estimated 3 children per 1000 live births, affecting males and females and all racial groups equally [2]. There appears to be no hereditary predilection for PWS within families. There are no known risk factors or ways to prevent PWS.

    Affordable and realistic three dimensional visualization technology can be applied to large scale constructive simulations such as the port simulation model, PORTSIM. These visualization tools enhance the experienced planner's ability to form mental models of how seaport operations will unfold when the simulation model is implemented and executed. They also offer unique opportunities to train new planners not only in the use of the simulation model but on the layout and design of seaports. Simulation visualization capabilities are enhanced by borrowing from work on interface design, camera control, and data presentation. Using selective fidelity, the designers of these visualization systems can reduce their time and efforts by concentrating on those features which yield the most value for their simulation. Offering the user various observational tools allows the freedom to simply watch or engage in the simulation without getting lost. Identifying the underlying infrastructure or cargo items with labels can provide useful information at the risk of some visual clutter. The PortVis visualization expands the PORTSIM user base which can benefit from the results provided by this capability, especially in strategic planning, mission rehearsal, and training. Strategic planners will immediately reap the benefits of seeing the impact of increased throughput visually without keeping track of statistical data. Mission rehearsal and training users will have an effective training tool to supplement their operational training exercises which are limited in number because of their high costs. Having another effective training modality in this visualization system allows more training to take place and more personnel to gain an understanding of seaport operations. This simulation and visualization training can be accomplished at lower cost than would be possible for the operational training exercises alone. The application of PORTSIM and PortVis will lead to more efficient

    The present experimental characterization of the mean and fluctuating flow field along the length of a simulated cylindrical port rocket chamber employed flow simulations in which ambient-temperature nitrogen was uniformly injected along the walls of a porous-tube chamber connected to a choked sonic nozzle. The data obtained indicate that velocity fluctuations near the head of the chamber generally decrease in intensity relative to the centerline speed over the first five port diameters. Regular velocity fluctuations then appear near the wall, just ahead of the transition to turbulent flow; vortical disturbances are noted to exhibit pairing as they move away from the wall. Both buoyant flow influences and flow spinning are discovered in the forward portions of the chamber.

    Underwater photogrammetry using consumer grade photographic equipment can be feasible for different applications, e.g. archaeology, biology, industrial inspections, etc. The use of a camera underwater can be very different from its terrestrial use due to the optical phenomena involved. The presence of the water and camera pressure housing in front of the camera act as additional optical elements. Spherical dome ports are difficult to manufacture and consequently expensive but at the same time they are the most useful for underwater photogrammetry as they keep the main geometric characteristics of the lens unchanged. Nevertheless, the manufacturing and alignment of dome port pressure housing components can be the source of unexpected changes of radial and decentring distortion, source of systematic errors that can influence the final 3D measurements. The paper provides a brief introduction of underwater optical phenomena involved in underwater photography, then presents the main differences between flat and dome ports to finally discuss the effect of manufacturing on 3D measurements in two case studies.

    Infection is a serious complication of breast augmentation and tissue expansion with inflatable devices. Several reports have shown that fungi may be able to survive, colonize, and even cause infection in saline-filled devices. The mechanism of how they penetrate, spread, and colonize inside the inflatable implants is not exactly understood. The authors assessed both the expander membrane and the port in terms of leakage and penetration of Candida albicans and Aspergillus niger in an in vitro model. Thirty saline-filled expanders connected to the injection port were placed in sterile containers filled with tryptic soy broth culture medium to simulate the clinical situation in phases I and II. Intact and multipunctured ports were used in the first and second phases of the study, respectively. Either the container or the implant was inoculated with one of these fungi, and six implants in containers without fungal inoculation served as controls. As a third phase, intraluminal survival of fungi was investigated in saline-filled containers (n = 12) in 21 days. The silicone membrane, with its intact connecting tube and port, was impermeable to these fungi, whereas both fungi were able to diffuse inside-out or outside-in through the punctured ports. C. albicans did not survive beyond 18 days in saline, whereas A. niger continued to multiply at day 21. Chemical analyses of the implant fluids revealed that the contents of the culture medium diffused into the implants in phases I and II. The data show that an intact silicone membrane is impermeable to fungi, and punctured ports allow translocation of fungi into the implants. Fungi can grow and reproduce in a saline-only environment, and their survival periods differ among the species. Furthermore, their survival may be enhanced by the influx of substances through the implant shell. PMID:15457030

    We describe a novel minimally invasive procedure: dual-port laparoscopic abdominoperineal resection using a SILS port, and report our experience of using this to treat ten patients with lower rectal cancer. A SILS port was placed in the left lower quadrant at the intended colostomy site. A 5-mm trocar was inserted at the umbilicus at the subsequent drain site. Via a standard laparoscopic medial-to-lateral approach, the inferior mesenteric artery and vein were ligated and total mesorectal excision was performed. Via a perineal approach, the specimen was retrieved from the perineal wound, and a sigmoid colostomy was created at the site of the SILS port. Ten consecutive patients with lower rectal cancer at clinical stage T3 or lower underwent the procedure at our institution. The procedure was completed successfully in all patients, without any intraoperative problems and all postoperative outcomes were satisfactory. Thus, dual-port laparoscopic abdominoperineal resection can be performed safely and feasibly in selected patients. PMID:26220049

    Purpose We review the literature and describe our technique for laparoendoscopic single-site orchidopexy using a glove port and rigid instruments. We assessed the feasibility and outcomes of this procedure. Materials and Methods We retrospectively reviewed the case records of all children who had undergone laparoendoscopic single-site orchidopexy by use of a surgical glove port and conventional rigid instruments for a nonpalpable intraabdominal testis between January 2013 and September 2014. Results Data from a total of 20 patients were collected. The patients' mean age was 18 months. All cases had a nonpalpable unilateral undescended testis. Fourteen patients (70%) had an undescended testis on the right side and six patients (30%) had an undescended testis on the left side. Seventeen patients underwent primary orchidopexy. Three patients underwent single-port laparoscopic Fowler-Stephens orchidopexy for the first and the second stage. Average operating time was 57 minutes (range, 40 to 80 minutes). No patient was lost to follow-up. At follow-up, 2 testes were found to have retracted out of the scrotum and these were successfully dealt with in a second operation. One testis was hypoplastic in the scrotal pouch. There were no signs of umbilical hernia. Conclusions Single-port laparoscopic orchidopexy using a glove port and rigid instruments is technically feasible and safe for various nonpalpable intraabdominal testes. However, surgical experience and long-term follow-up are needed to confirm the superiority of this technique. PMID:26568797

    The transshipment is an important issue in the current marine transportation. This paper constructed a mathematical programming model to elaborate the transshipment port selection for the shipping company. This model is tested by the data collected from the ports of Hong Kong and Kaohsiung. The results show that this model can be used to explain the transshipment competition relationship between the ports of Hong Kong and Kaohsiung well. A sensitivity analysis was also executed. The sensitivity analysis results showed that both the port of Hong Kong and Kaohsiung should decrease the charges of port and increase the efficiency of loading and discharging. Based on the sensitivity analysis results, some interesting conclusions and helpful suggestions were obtained for the managers of the ports of Hong Kong and Kaohsiung to improve their port management.

    Single-port laparoscopic surgery (SPLS) is implemented through a tailored minimal single incision through which a number of laparoscopic instruments access. Introduction of operation-customized port system, utilization of a camera without a separate external light, and instruments with different lengths has brought the favorable environment for SPLS. However, performing SPLS still creates several hardships compared to multiport laparoscopic surgery; a single-port system inevitably leads to clashing of surgical instruments due to crowding. To overcome such difficulties, investigators has developed novel concepts and maneuvers, including the concept of inverse triangulation and the maneuvers of pivoting, spreading out dissection, hanging suture, and transluminal traction. The final destination of SPLS is expected to be a completely seamless operation, maximizing the minimal invasiveness. Specimen extraction through the umbilicus can undermine cosmesis by inducing a larger incision. Therefore, hybrid laparoscopic technique, which combined laparoscopic surgical technique with natural orifice specimen extraction (NOSE)--i.e., transvaginal or transanal route-, has been developed. SPLS and NOSE seemed to be the best combination in pursuit of minimal invasiveness. In the near future, robotic SPLS with natural orifice transluminal endoscopic surgery's way of specimen extraction seems to be pursued. It is expected to provide a completely or nearly complete seamless operation regardless of location of the lesion in the abdomen. PMID:24574772

    Background and Objective: Robotic upper urinary tract surgery is in most of the cases performed utilizing a standard 5 port configuration. Fewer ports can potentially produce a less invasive operation. Taking in consideration the above we report a novel technique for robot assisted laparoscopic partial nephrectomy utilizing fewer ports and we test its feasibility and safety profile. Methods: Data on 11 robot-assisted laparoscopic partial nephrectomies performed by using our technique from February 2015 through June 2015 were retrospectively analyzed. The robotic platform used was DaVinci Xi (Intuitive Surgical, Inc., Sunnyvale, California, USA) with a 3-arm setup. The AirSeal system (SurgiQuest, Milford, Connecticut, USA) was used as a port allowing simultaneous introduction of 2 instruments for the bedside surgeon, obviating the need for an additional (fourth) robotic arm. A long suction-and-irrigation device and atraumatic grasping forceps were used. Both instruments were introduced through the trocar of the AirSeal system, making simultaneous introduction and use possible. We preferred the long suction-and-irrigation device, because it minimizes collision of the instruments. Results: Mean age and BMI of the patients were 55 ±14.6 y and 29.18 ± 6.85, respectively. Seven tumors were on the right side and 4 were on the left. The mean size of the tumors was 32.45 mm (± 11.31). Surgical time was 132.2 minutes (±37.17), with an estimated blood loss and ischemia time of 103.63 mL (±65.92) and 16.72 minutes (±9.52), respectively. One patient had postoperative bleeding that was resolved without transfusion. The median hospitalization period was 3.9 d (±0.53). Loss of intra-abdominal pressure was not observed, and pressure was stable at 10 mm Hg. Conclusion: The AirSeal System and its valveless trocar eliminated the need for an additional port placement in our series. The technique is feasible, safe, and reproducible; therefore, it may be implemented in selected

    Purpose. The purpose of this study was to evaluate radiological-interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Materials and Methods. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5-F angiographic catheters (pigtail; Sos Omni), gooseneck snares, or combinations thereof. Results. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological-interventional port catheter correction was successful. In two patients port catheter malposition correction was not possible, because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. Conclusions. We conclude that in migrated catheter tips radiological-interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis port catheter correction is often more challenging.

  2. Is multi-port ATE in your future

    NASA Astrophysics Data System (ADS)

    Monie, V.; Kovel, D. M.

    The history of ATE is surveyed, with attention given to significant technical advances made during the past few years. Multi-port testing is seen as a logical extension of engineering attempts to extract the maximum value for the ATE dollar invested. Particular attention is given to the economics of multi-port ATE. It is shown that the cost/throughput ratio of a dual-port test set is 40% greater than a single port test set. The benefits of increased test set availability and the associated logistics costs are stressed. The numerous economic benefits are matched by the technical advantages, which are also discussed in detail. Potential problems in a dual-port ATE are identified, and solutions are suggested. It is shown that a successful dual-port ATE is one that not only solves real-life testing problems but also solves problems of resource competition and allocation.

  11. An alternative to the traveling-wave approach for use in two-port descriptions of acoustic bores

    NASA Astrophysics Data System (ADS)

    Ducasse, Eric

    2002-12-01

    For more than a decade, the digital waveguide model for musical instruments has been improved through the simulation of cylindrical and conical bores. But several difficulties remain, such as instabilities due to growing exponentials which appear when two conical bores are connected with decreasing taper. In this paper, an alternative overcoming these difficulties is proposed and can be extended to shapes other than cylinders, cones, and hyperbolic horns. A two-port model with more general state variables than usual traveling waves works efficiently for any shape without discontinuities in cross section. The equations for connecting separate elements at discontinuities make this two-port model appropriate for use in time domain simulation of the physical behavior of the wind instrument and its interactions with the player. The potential of this new approach is illustrated by several detailed examples.

  12. Compressor ported shroud for foil bearing cooling

    DOEpatents

    Elpern, David G.; McCabe, Niall; Gee, Mark

    2011-08-02

    A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

  13. Recent sedimentation, northeastern Port Valdez, Alaska

    NASA Astrophysics Data System (ADS)

    Palmer, Harold D.

    1981-09-01

    Sediments accumulating on the northeastern shore of Port Valdez, a fjord leading to Prince William Sound in southern Alaska, are derived from both deltaic and alluvial fan processes. The resulting thick wedge of Recent silts, sands, shells and gravels lies atop irregular ridges of local graywacke bedrock and scattered till deposits. Seismic reflection profiling augmented by soil borings indicates that rapid infilling and upbuilding has occurred at this site. Evidence of slumping suggests general instability of steep submarine slopes in an area characterized by strong earthquakes and large tidal ranges.

    1993-05-01

    We discussed a second entry port for the Accelerator Test Facility (ATF) injection system at Brookhaven National Laboratory, which consists of a photocathode rf gun and a straight - ahead beamline directly into the 50 MeV linac. The proposed second entry port should improve the beam quality and lower the emittance needed for FEL (Free Electron Laser), and laser - acceleration experiments. A discussion on the laser driven high brightness photoelectrons through the primary entry port (a low energy 180 degrees achromatic double bend transport line) now in operation, and a beam analysis for the proposed secondary port is also given.

    Single-incision laparoscopic surgery has gained increasing attention due to its potential to improve the benefits of laparoscopic surgery. However, inconvenience remains for inexperienced surgeons during surgery when instruments conflict with each other, and a glove port is used hesitantly for such diagnosis related groups (DRG) because of its high cost. Authors made a new glove port by an odd surgical gloves and one wound protectors. This glove port is ease to make besides being convenient to us, and inexpensive. This new glove port has the benefit of easy utilization and cost effectiveness for surgeons performing single-incision laparoscopic surgery. PMID:26576410

    Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data. PMID:25437581

    Purpose: To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data.Methods: One hundred and twelve central venous catheters with peripherally placed access ports were placed under sonographic guidance in 109 patients over a 4-year period. Ports were placed for the administration of chemotherapy, hyperalimentation, long-term antibiotic therapy, gamma-globulin therapy, and frequent blood sampling. A vein in the upper arm was accessed in each case and the catheter was passed to the superior vena cava or right atrium. Povidone iodine skin preparation was used in the first 65 port insertions. A combination of Iodophor solution and povidone iodine solution was used in the last 47 port insertions. Forty patients received low-dose (1 mg) warfarin sodium beginning the day after port insertion. Three patients received higher doses of warfarin sodium for preexistent venous thrombosis. Catheter performance and complications were assessed and compared with published data.Results: Access into the basilic or brachial veins was obtained in all cases. Ports remained functional for a total of 28,936 patient days. The port functioned in 50% of patients until completion of therapy, or the patient's expiration. Ports were removed prior to completion of therapy in 18% of patients. Eleven patients (9.9% of ports placed) suffered an infectious complication (0.38 per thousand catheter-days)-in nine, at the port implantation site, in two along the catheter. In all 11 instances the port was removed. Port pocket infection in the early postoperative period occurred in three patients (4.7%) receiving a Betadine prep vs two patients (4.2%) receiving a standard O.R. prep. This difference was not statistically significant (p = 0.9). Venous thrombosis occurred in three patients (6.8%) receiving warfarin sodium and in two patients (3%) not receiving warfarin sodium. This difference was not statistically significant

    Today, the vast majority of electron storage rings delivering synchrotron radiation for general user operation offer a dedicated infrared port. There is growing interest expressed by various scientific communities to exploit the mid-IR emission in microspectroscopy, as well as the far infrared (also called THz) range for spectroscopy. Compared with a thermal (laboratory-based source), IR synchrotron radiation sources offer enhanced brilliance of about two to three orders of magnitude in the mid-IR energy range, and enhanced flux and brilliance in the far-IR energy range. Synchrotron radiation also has a unique combination of a broad wavelength band together with a well defined time structure. Thermal sources (globar, mercury filament) have excellent stability. Because the sampling rate of a typical IR Fourier-transform spectroscopy experiment is in the kHz range (depending on the bandwidth of the detector), instabilities of various origins present in synchrotron radiation sources play a crucial role. Noise recordings at two different IR ports located at the Swiss Light Source and SOLEIL (France), under conditions relevant to real experiments, are discussed. The lowest electron beam fluctuations detectable in IR spectra have been quantified and are shown to be much smaller than what is routinely recorded by beam-position monitors. PMID:22186638

  16. Reinforcement learning for port-hamiltonian systems.

    PubMed

    Sprangers, Olivier; Babuška, Robert; Nageshrao, Subramanya P; Lopes, Gabriel A D

    2015-05-01

    Passivity-based control (PBC) for port-Hamiltonian systems provides an intuitive way of achieving stabilization by rendering a system passive with respect to a desired storage function. However, in most instances the control law is obtained without any performance considerations and it has to be calculated by solving a complex partial differential equation (PDE). In order to address these issues we introduce a reinforcement learning (RL) approach into the energy-balancing passivity-based control (EB-PBC) method, which is a form of PBC in which the closed-loop energy is equal to the difference between the stored and supplied energies. We propose a technique to parameterize EB-PBC that preserves the systems's PDE matching conditions, does not require the specification of a global desired Hamiltonian, includes performance criteria, and is robust. The parameters of the control law are found by using actor-critic (AC) RL, enabling the search for near-optimal control policies satisfying a desired closed-loop energy landscape. The advantage is that the solutions learned can be interpreted in terms of energy shaping and damping injection, which makes it possible to numerically assess stability using passivity theory. From the RL perspective, our proposal allows for the class of port-Hamiltonian systems to be incorporated in the AC framework, speeding up the learning thanks to the resulting parameterization of the policy. The method has been successfully applied to the pendulum swing-up problem in simulations and real-life experiments. PMID:25167564

    The Physical Oceanographic Real-Time System (PORTS) provides observations of tides, tidal currents, and meteorological conditions in real-time. The San Francisco Bay PORTS (SFPORTS) is a decision support system to facilitate safe and efficient maritime commerce. In addition to real-time observations, SFPORTS includes a nowcast numerical model forming a San Francisco Bay marine nowcast system. SFPORTS data and nowcast numerical model results are made available to users through the World Wide Web (WWW). A brief overview of SFPORTS is presented, from the data flow originated at instrument sensors to final results delivered to end users on the WWW. A user-friendly interface for SFPORTS has been designed and implemented. Appropriate field data analysis, nowcast procedures, design and generation of graphics for WWW display of field data and nowcast results are presented and discussed. Furthermore, SFPORTS is designed to support hazardous materials spill prevention and response, and to serve as resources to scientists studying the health of San Francisco Bay ecosystem. The success (or failure) of the SFPORTS to serve the intended user community is determined by the effectiveness of the user interface.

  18. Port site metastasis in prostate cancer.

    2015-01-01

    Port-site metastasis of prostatic adenocarcinoma is rare and usually associated with poor prognosis. We report a case of a young man with a rising prostate-specific antigen (PSA) 4.5 years after robot-assisted laparoscopic prostatectomy (RALP) and extended pelvic lymphadenectomy (ePLND) for a Gleason 7 (4+3) prostate cancer (pT3b pN0 cM0). Choline positron emission tomography-computed tomography (PET-CT) demonstrated a PET positive subcutaneous recurrence in a previous trocar site accompanied by a PET positive ipsilateral inguinal lymph node. Excision of both lesions was performed, confirming the diagnosis of metastatic prostate cancer. The patient's PSA dropped significantly postoperatively enabling postponement of androgen deprivation treatment up to this date. The etiology of port-site metastasis is multifactorial, including patient and surgery related factors. Such metastases have been scarcely reported following ePLND with or without RALP. Certain surgical precautions can be made to prevent the occurrence. We summarize previously reported mechanisms of development and possible precautionary measures. PMID:26225184

    The aim of this study is to analyze the current literature on single port radical prostatectomy (LESS-RP). Single port radical prostatectomy laparoendoscopic (LESS-RP) has established itself as a challenge for urological community, starting with the proposal of different approaches: extraperitoneal, transperitoneal and transvesical, initially described for laparoscopy and then laparoscopy robot-assisted. In order to improve the LESS-RP, new instruments, optical devices, trocars and retraction mechanisms have been developed. Advantages and disadvantages of LESS-RP are controversial, while some claim that it is a non-trustable approach, regarding the low cases number and technical difficulties, others acclaim that despite this facts some advantages have been shown and that previous described difficulties are being overcome, proving this is novel proposal of robotics platform, the Da Vinci SP, integrating the system into "Y". The LESS-RP approach gives us a new horizon and opens the door for rapid standardization of this technique. The few studies and short series available can be result of a low interest in the application of LESS-RP in prostate, probably because of the technical complexity that it requires. The new robotic platform, the da Vinci SP, shows that it is clear that the long awaited evolution of robotic technologies for laparoscopy has begun, and we must not lose this momentum. PMID:27072150

    Looking for a virtually "scarless" surgery mini-laparoscopy (ML) could be a viable alternative to conventional laparoscopy. ML is a reproducible technique and allows for the preservation of the triangulation concept, the cornerstone of laparoscopic surgery. Drawback of ML could be the poor performance of miniaturized instruments that could affect the confidence of the surgeon and limit the indications. The recent availability of a novel mini-laparoscopic platform in our center expanded the indications of ML to radical nephrectomy even in cases of large renal tumors in kidneys with abundant perirenal fat. The platform is composed by mini-instruments with the peculiarity of a 2.9-mm shaft that is mounted on a handle and a jaw that are comparable in size and performance to those of conventional instruments, increasing the ergonomy and the confidence perceived by the surgeon. Allowing for inclusion criteria, nine consecutive patients were enrolled in our prospective study and underwent percutaneously assisted "two-ports" radical nephrectomy. Preliminary data showed that the novel platform allowed us to perform a safe and effective procedure with acceptable perioperative outcomes and apparent improvements in cosmesis. Larger sample size and comparative studies are needed to confirm these findings. PMID:27033860

  4. A demonstration of a low cost approach to security at shipping facilities and ports

    Government funding for the security at shipping facilities and ports is limited so there is a need for low cost scalable security systems. With over 20 million sea, truck, and rail containers entering the United States every year, these facilities pose a large risk to security. Securing these facilities and monitoring the variety of traffic that enter and leave is a major task. To accomplish this, the authors have developed and fielded a low cost fully distributed building block approach to port security at the inland Port of Catoosa in Oklahoma. Based on prior work accomplished in the design and fielding of an intelligent transportation system in the United States, functional building blocks, (e.g. Network, Camera, Sensor, Display, and Operator Console blocks) can be assembled, mixed and matched, and scaled to provide a comprehensive security system. The following functions are demonstrated and scaled through analysis and demonstration: Barge tracking, credential checking, container inventory, vehicle tracking, and situational awareness. The concept behind this research is "any operator on any console can control any device at any time."

  14. Climate variability and Port wine quality

    2010-05-01

    Recent warming trends for Portugal have been found to be steepest in winter and spring and more pronounced for minimum than for maximum values of temperature (Miranda et al, 2002). These trends and associated changes in temperature and precipitation regimes may exert strong influences on agriculture systems. For instance, high values of the North Atlantic Oscillation (NAO) index have been shown to significantly reduce precipitation over Iberia and therefore induce low yield wheat crops in Portugal (Gouveia and Trigo, 2006). Port wine is produced from grapes grown in selected areas of the Douro valley, the so-called Região Demarcada do Douro, the first wine-producing region of the world (dating from 1758). A vintage wine is made from grapes that were grown and harvested in a single specified year and is classified as such because of the above average quality, a status that is attributed by Port houses in their best years. The Douro region presents distinctive climatic, topographic and soil characteristics. While the latest factors are fixed in time, the former may considerably change from year to year, exposing the Port wine productions to a large risk associated to interannual and intra-seasonal climatic variations. It is therefore to be expected that high quality wines are generally associated to optimum climatic conditions. In this work we have performed an analysis of the distinct behaviour of several meteorological fields in vintage versus non-vintage years. The relative importance of maximum and minimum temperature, precipitation and frost days is assessed for each individual month of the vegetative cycle and their importance to a high quality wine year is evaluated. Composites of 500 hPa geopotential height and sea level pressure fields over the Euro Atlantic region are also compared for vintage and non-vintage years. Results reveal a strong dependence of vintage production on maximum temperature and precipitation during spring and summer (the growing season

    Port wine stains are categorized as a benign capillary vascular malformation, which is hard to cure. In this paper, a photoacoustic microscopy system, which integrated a two-dimensional scanning galvanometer, an objective lens and a focused ultrasound transducer, was designed for noninvasive imaging of blood vessels of port wine stains model in vivo. Cock comb was chosen as the port wine stains model in the experiment. The blood vessels in x-y plane and x-z plane were imaged clearly. Experimental results demonstrate that photoacoustic microscopy can image the blood vessels of port wine stains model in vivo with high contrast and high resolution. It has the potential for clinical applications in detecting the blood vessels in port wine stains skin. PMID:22635179

    Laparoscopy is the gold standard in gynecological surgery. Single-port laparoscopic surgery, has been developed in order to improve minimally invasive surgery. We analyzed single-port approach in benign gynecologic pathology and made a bibliographic research on Pubmed and Medline from January 2000 to January 2015. From what emerges from the papers taken into consideration, single-port laparoscopy can be used for salpingostomy or salpingectomy to treat tubal ectopic pregnancy, benign adnexal disease (ovarian cystectomy, salpingo-oophorectomy), and for hysterectomy. We do not have enough data for complex procedures like myomectomy or hysteropexy. Robotic single-port laparoscopy seems to be a very attractive perspective and its use in benign gynecology surgery is expanding. More and more ergonomic limitations of single-port laparoscopy are corrected by development of articulated or flexible instruments and camera. Beyond these preliminary results, more ample prospective studies with an adapted and standardized instrumentation are thus essential to highlight real profits. PMID:25714874

    The increased demand for freight movements through international ports of entry and the signing of the North American Free Trade Agreement (NAFTA) have increased freight traffic at border ports of entry. The State-of-the-Art Port of Entry Workshop initiated a dialogue among technologists and stakeholders to explore the potential uses of technology at border crossings and to set development priorities. International ports of entry are both information and labor intensive, and there are many promising technologies that could be used to provide timely information and optimize inspection resources. Participants universally held that integration of technologies and operations is critical to improving port services. A series of Next Steps was developed to address stakeholder issues and national priorities, such as the National Transportation Policy and National Drug Policy. This report documents the views of the various stakeholders and technologists present at the workshop and outlines future directions of study.

    A new methodology has been designed to identify and rank the significant environmental aspects in sea ports. The main objective of the Strategic Overview of Significant Environmental Aspects (SOSEA) is to help port managers to identify significant environmental aspects and to reinforce the awareness about them in order to prioritise work in environmental management. Developed in close collaboration with port environmental managers and tested in a set of ports, it is a user-friendly tool that can be applied in approximately half a working day. It is based on ISO 14001 vocabulary and requirements and it can be considered as the base for the implementation of any Environmental Management System for port communities. PMID:15946703

  19. Experimental and Computational Investigation of Multiple Injection Ports in a Convergent-Divergent Nozzle for Fluidic Thrust Vectoring

    NASA Technical Reports Server (NTRS)

    Waithe, Kenrick A.; Deere, Karen A.

    2003-01-01

    A computational and experimental study was conducted to investigate the effects of multiple injection ports in a two-dimensional, convergent-divergent nozzle, for fluidic thrust vectoring. The concept of multiple injection ports was conceived to enhance the thrust vectoring capability of a convergent-divergent nozzle over that of a single injection port without increasing the secondary mass flow rate requirements. The experimental study was conducted at static conditions in the Jet Exit Test Facility of the 16-Foot Transonic Tunnel Complex at NASA Langley Research Center. Internal nozzle performance was obtained at nozzle pressure ratios up to 10 with secondary nozzle pressure ratios up to 1 for five configurations. The computational study was conducted using the Reynolds Averaged Navier-Stokes computational fluid dynamics code PAB3D with two-equation turbulence closure and linear Reynolds stress modeling. Internal nozzle performance was predicted for nozzle pressure ratios up to 10 with a secondary nozzle pressure ratio of 0.7 for two configurations. Results from the experimental study indicate a benefit to multiple injection ports in a convergent-divergent nozzle. In general, increasing the number of injection ports from one to two increased the pitch thrust vectoring capability without any thrust performance penalties at nozzle pressure ratios less than 4 with high secondary pressure ratios. Results from the computational study are in excellent agreement with experimental results and validates PAB3D as a tool for predicting internal nozzle performance of a two dimensional, convergent-divergent nozzle with multiple injection ports.

    Objective To present seven cases of single incision laparoscopic nephrectomy and nephroureterectomy in children as a recent videoscopic innovation. Patients and methods Seven children with nonfunctioning kidneys, three with multicystic dysplastic kidneys, two with end-stage renal nephropathy due to vesicoureteral reflux, and two with giant hydronephrosis were qualified to nephrectomy or nephroureterectomy. The surgery was performed transperitoneally using single incision access laparoscopy. The operative time was in the range of 50-90 min. Results There were no intraoperative or postoperative complications. The patients were discharged on the third postoperative day. The incision scars were hidden inside the umbilicus. Conclusions Nephrectomy or nephroureterectomy using a single transumbilical port in children is a feasible and efficacious technique. The advantages are shortened convalescence, excellent cosmetic results, and reduction of potential wounds complications. However, clear indication of single site laparoscopic procedures in children remains to be clarified. PMID:24578903

    The tsunamis that have occurred in many places around the world over the past decade have taken a heavy toll on human lives and property. The eastern coast of the Korean Peninsula is not safe from tsunamis, particularly the eastern coastal areas, which have long sustained tsunami damage. The eastern coast had been attacked by 1983 and 1993 tsunami events. The aim of this study was to mitigate the casualties and property damage against unexpected tsunami attacks along the eastern coast of the Korean Peninsula by developing a proper tsunami response system for important ports and harbors with high population densities and high concentrations of key national industries. The system is made based on numerical and physical modelings of 3 historical and 11 virtual tsunamis events, field surveys, and extensive interviews with related people.

A survey by the Port Elizabeth Deaf Association on workmen from Cadbury (Pty) Ltd was undertaken in 1973 and on a second group in 1974 and the results are published and discussed. Although the numbers of workmen were small, the results suggest that widespread testing will unearth many cases of unsuspected hearing loss. The implications as applied to industry at large are discussed and the difficulties in adequately assessing large numbers of workmen with adequately trained audiometric testers are stressed. A suggestion is made that mobile clinics under the control of Chambers of Industries would be the most efficient way of approaching the screening problem, and an estimated cost structure in the setting up of such a clinic is introduced.

    This study on the performance characteristics of existing solar technologies in a maritime environment was funded by an award given to The Port of Galveston (POG) from the U.S. Department of Energy (DOE). The study includes research performed by The Center for Advanced Materials at the University of Houston (UH). The UH researchers examined how solar cell efficiencies and life spans can be improved by examining the performance of a variety of antireflective (AR) coatings mounted on the top of one of the POG’s Cruise Terminals. Supplemental supporting research was performed at the UH laboratories. An educational Kiosk was constructed with a 55” display screen providing information about solar energy, the research work UH performed at POG and real time data from the solar panels located on the roof of the Cruise Terminal. The Houston Advanced Research Center (HARC) managed the project.

    Recent developments have shown that the use of buried electronic devices or body implants has been becoming prevalent. Such low power devices are being powered up through non-contact means utilizing inductive coupling from external powering source. Inductive coupling not only solves the issue of energy availability but helps collecting the sensed data that can be archived or used for subsequent monitoring purposes. This paper analyses the performance of two-port and three-port inductive links in terms of power sent, power received and power transfer efficiency. All the above mentioned parameters have been plotted using analytical approach and obtaining simulation where required. The effect of mutual coupling has been studied in detail for both systems and demonstrated by plotting the power transfer efficiency for different values of the coefficient of coupling (k) using MATLAB. Results show that power transfer efficiency depends highly upon the value of k.

    Lawson, J. D.

    1992-04-01

    An informal descriptive account is first given of the emittance concept and its underlying physical basis. This is followed by a discussion of the connection between emittance and entropy, and a number of questions relating to problems of current interest concerning such topics as emittance growth and equipartition between different degrees of freedom are raised. Although no new results are obtained, it is hoped that the discussion may be helpful in the search for new insights. The paper differs from that presented at the conference, and contains ideas which arose in discussion with T. P. Wangler at Los Alamos after the conference.

    Purpose Single-port laparoscopic splenectomy has been performed sporadically. The aim of this study is to assess our experience with single-port laparoscopic splenectomy compared to conventional multiport laparoscopic surgery for the usual treatment modality for various kinds of splenic disease. Methods Between October 2008 to February 2014, 29 patients underwent single-port laparoscopic splenectomy and 32 patients received multiport laparoscopic splenectomy. We retrospectively analyzed the clinical outcomes of single-port group and multiport group. Results The body mass index and disease profiles of the both groups were similar. The operative times of single-port and multiport group were 113.6 ± 39.9 and 95.9 ± 38.9 minutes, respectively (P = 0.946). The operative blood loss of the two groups were 295.8 ± 301.3 and 322.5 ± 254.5 mL (P = 0.582). Postoperative retrieved splenic weight of the single-port and multiport groups were 283.9 ± 300.7 and 362.3 ± 471.8 g, respectively (P = 0.261). One single-port partial splenectomy and 6 multiport partial splenectomies were performed in this study. There was one intraoperative gastric wall injury. It occurred in single-port group, which was successfully managed during the operation. Each case was converted to laparotomy in both groups due to bleeding. There was one mortality case in the multiport laparoscopic splenectomy group, which was not related to the splenectomy. Mean hospital stay of the single-port and multiport group was 5.8 ± 2.5 and 7.3 ± 5.2 days respectively (P = 0.140). Conclusion Single-port laparoscopic splenectomy seems to be a feasible approach for various kinds of splenic disease compared to multiport laparoscopic surgery. PMID:26236693

    We present a new next generation domain search engine called MedicoPort. MedicoPort is a medical search engine designed for the users with no medical expertise. It is enhanced with the domain knowledge obtained from Unified Medical Language System (UMLS) to increase the effectiveness of the searches. The power of the system is based on the ability to understand the semantics of web pages and the user queries. MedicoPort transforms a keyword search into a conceptual search. Through our system we present a topical web crawling technique and indexing techniques empowered by the semantics information. MedicoPort aims to generate maximum output with semantic value using minimum input from the user. Since MedicoPort is designed to help people seeking information about health on the web, our target users are not medical specialists who can effectively use the special jargon of medicine and access medical databases. Medical experts have the advantage of shrinking the answer set by expressing several terms using medical terminology. MedicoPort provides the same advantage to its users through the automated use of the medical domain knowledge in the background. The results of our experiments indicate that, expanding the queries with domain knowledge, such as using the synonyms and partially or contextually relevant terms from UMLS, increase dramatically the relevance of an answer set produced by MedicoPort and the number of retrieved web pages that are relevant to the user request.

    Backgrounds Single-port thoracoscopic segmentectomy is a challenging option in the early stages of lung cancer. The purpose of this study was to determine the feasibility of single-port video-assisted thoracoscopic surgery (VATS) segmentectomy compared to conventional multi-port VATS. Methods A total of 45 patients underwent pulmonary segmentectomy by video-assisted thoracoscopic surgery between March 2006 and October 2015. We analyzed the operative outcomes of segmentectomy by surgical approach (34 single-port versus 11 multi-port). Results Twenty-three primary lung cancers (51.1%), 16 benign lung diseases (35.6%), and 6 secondary lung cancers (13.3%) were diagnosed and included in our study. In 29 malignancy cases (64.4%), the mean tumor size was 1.8±0.7 (range, 1–3.5) cm. Twenty patients (44.4%) underwent preoperative localization with hook-wire and radiocontrast. The most frequent operated segment was the left upper divisional segment (n=9, 30%). There was no significant difference in operation time (P=0.073), the number of dissected lymph nodes (P=0.310), intraoperative events (P=0.412), and the development of prolonged air leak (>5 days) (P=0.610) between the single-port and multi-port VATS segmentectomy groups. There was a reduction in postoperative morbidity (P<0.001) and hospital stay (P=0.029) in the single-port VATS group. Conclusions Single-port VATS segmentectomy for early lung cancer and benign lung disease, is a safe and feasible option for patients undergoing pulmonary segmentectomy. PMID:27014475

    The purpose of this study was to evaluate the long-term follow-up results of subcutaneous venous ports implanted in patients with bilateral mastectomies. We retrospectively reviewed the hospital charts and the electronic database of 17 patients with bilateral mastectomies whom had venous port implantation in our interventional radiology suit. A total of 17 ports were implanted to the paramedian (n = 3) and anterolateral (standard; n = 12) chest wall, on the trapezius muscle (n = 1), and to the antecubital fossa (n = 1). The mean age was 48.29 years (range: 35-60 years). The mean time interval from time of surgery to port implantation was 34 months (range: 1-84 months). The mean follow-up time was 15 months (range: 7-39 months). Follow-up parameters and classification of the complications was defined according to the SIR guidelines. No procedure-related complication occurred. A single case of mild late infection was noted and the infection rate was 0.19/1000 catheter days. Infusion chemotherapy administration was still going on in eight patients. Two patients died during the follow-up and four patients were lost after 6 months. Port removal was performed in three patients at follow-up because of the end of treatment. One trapezius port and one paramedian port weres among the removed ports without any problem. Although we have a limited number of patients, port placement to the anterior chest wall, either paramedian or anterolateral, on the trapezius muscle or to the antecubital fossa depending on the extent of the bilateral breast surgeries that can be performed with low complication rates by a careful patient and anatomical location selection by involving the patients in the decision-making process. We believe that patient education and knowledge of possible complications have high importance in follow-up.

    Conventional surgical technique of subcutaneous venous port placement describes dissection of the port pocket to the pectoralis fascia and suture fixation of the port to the fascia to prevent inversion of the device within the pocket. This investigation addresses the necessity of that step. Between October 8, 2004 and October 19, 2007, 558 subcutaneous chest ports were placed at our institution; 24 cases were excluded from this study. We performed a retrospective review of the remaining 534 ports, which were placed using standard surgical technique with the exception that none were sutured into the pocket. Mean duration of port use, total number of port days, indications for removal, and complications were recorded and compared with the literature. Mean duration of port use was 341 days (182,235 total port days, range 1-1279). One port inversion/flip occurred, which resulted in malfunction and necessitated port revision (0.2%). Other complications necessitating port removal included infection 26 (5%), thrombosis n = 2 (<1%), catheter fracture/pinch n = 1 (<1%), pain n = 2 (<1%), and skin erosion n = 3 (1%). There were two arrhythmias at the time of placement; neither required port removal. The overall complication rate was 7%. The 0.2% incidence of port inversion we report is concordant with that previously published, although many previous reports do not specify if suture fixation of the port was performed. Suture fixation of the port, in our experience, is not routinely necessary and may negatively impact port removal.

    Les agressions sexuelles portent atteinte à l'intégrité physique et psychologique des personnes qui en sont victimes et entraînent des conséquences néfastes. Le viol constitue la forme la plus accomplie de ces agressions. Cette étude rétrospective visait à répertorier les cas de violences sexuelles enregistrés auprès des greffes du tribunal et de la cour criminelle de Port-Gentil, et d'en donner une approche épidémiologique et criminologique. La prévalence des agressions sexuelles judiciarisées à Port-Gentil est de 15 cas par an. Parmi ces 45 dossiers d'agression sexuelle, 23 dossiers concernaient un attentat à la pudeur (51,1%) dont 18 cas impliquaient un mineur de moins de 15 ans (78,2% des attentats à la pudeur). Six dossiers concernaient une tentative de viol (13,3%). Onze dossiers concernaient un viol sur une femme de plus de 15 ans (24,4%). Deux dossiers concernaient un outrage public à la pudeur (4,4%) et 3 un détournement de mineur (6,6%). Les victimes étaient âgées de 4 à 65 ans avec un âge moyen de 13,4 ans. La plupart des victimes provenaient d'un milieu social défavorisé, prolétaire (61,1%). Les agresseurs étaient âgés de 16 à 62 ans avec un âge moyen de 29,6. Il importe de se pencher sur ce phénomène pour comprendre les enjeux que représentent les agressions sexuelles. Il faudra prendre en considération la dénonciation de l'agression sexuelle, le traumatisme subi et la prévention de tels crimes. PMID:24396558

    Exposure to diesel engine exhaust has been linked to increased cancer risk and cardiopulmonary diseases. Diesel exhaust is a complex mixture of chemical substances, including a particulate fraction mainly composed of ultrafine particles, resulting from the incomplete combustion of fuel. Diesel trucks are known to be an important source of diesel-related air pollution, and areas with heavy truck traffic are associated with higher air pollution levels and increased public health problems. Several indicators have been proposed as surrogates for estimating exposures to diesel exhaust but very few studies have focused specifically on monitoring the ultrafine fraction through the measurement of particle number concentrations. The aim of this study is to assess occupational exposures of gate controllers at the port of Montreal, Canada, to diesel engine emissions from container trucks by measuring several surrogates through a multimetric approach which includes the assessment of both mass and number concentrations and the use of direct reading devices. A 10-day measurement campaign was carried out at two terminal checkpoints at the port of Montreal. Respirable elemental and organic carbon, PM1, PM2.5, PMresp (PM4), PM10, PMtot (inhalable fraction), particle number concentrations, particle size distributions, and gas concentrations (NO2, NO, CO) were monitored. Gate controllers were exposed to concentrations of contaminants associated with diesel engine exhaust (elemental carbon GM = 1.6 µg/m(3); GSD = 1.6) well below recommended occupational exposure limits. Average daily particle number concentrations ranged from 16,544-67,314 particles/cm³ (GM = 32,710 particles/cm³; GSD = 1.6). Significant Pearson correlation coefficients were found between daily elemental carbon, PM fractions and particle number concentrations, as well as between total carbon, PM fractions and particle number concentrations. Significant correlation coefficients were found between particle number

    An innovative method to obtain fMRI resting-state network maps during non-invasive electrical stimulation of the brain (ESB) was developed and tested. Five healthy volunteers participated in 2 fMRI sessions. In session one, a transcranial direct current stimulator (tDCS) was applied placing the positive electrode (31.5 cm(2)) over the right M1 of the cortex and the negative electrode (31.5 cm(2)) over the left supra-orbital area of the head. In session two, a monophasic pulsed current stimulator (tPCS) was applied using the identical electrode placement. Imaging was performed on a Siemens 3T Tim Trio scanner with a 12-channel head coil. At each session, five consecutive functional scans were obtained: 1) resting-state without stimulation (Rest-1), 2) a motor scan consisting of self-paced, bilateral finger-thumb opposition task, 3) resting-state with ESB (Stim-1), 4) resting-state without stimulation (Rest-2), and 5) resting-state with ESB, replicating Stim-1 (Stim-2). Data were analyzed using AFNI and MATLAB. For motor task fMRI analysis, a general linear model (GLM) determined the voxels in the right and left M1 that were significantly correlated with the motor task paradigm. The resting-state time series from the voxels in the R-M1 were averaged and the resulting time series used as a regressor in a GLM analysis to identify M1 connectivity maps. Connectivity maps were quantified as R(2) values, and then combined to give overlap maps for each of the experimental conditions. Fourier analysis determined the energy in the normalized signal average time courses extracted from L-M1 and R-M1 for each of the resting-state scans. Both tDCS and tPCS lowered the R(2) values and energy of the averaged time course in the right and left M1 ROI. The effect of the tPCS appeared more pronounced and less variable among subjects. Applying non-invasive ESB during fMRI scanning may down regulate the motor cortex's resting-state network connectivity. PMID:21696709

    Port-O-Sim is a software application that supports engineering modeling and simulation of launch-range systems and subsystems, as well as the vehicles that operate on them. It is flexible, distributed, object-oriented, and realtime. A scripting language is used to configure an array of simulation objects and link them together. The script is contained in a text file, but executed and controlled using a graphical user interface. A set of modules is defined, each with input variables, output variables, and settings. These engineering models can be either linked to each other or run as standalone. The settings can be modified during execution. Since 2001, this application has been used for pre-mission failure mode training for many Range Safety Scenarios. It contains range asset link analysis, develops look-angle data, supports sky-screen site selection, drives GPS (Global Positioning System) and IMU (Inertial Measurement Unit) simulators, and can support conceptual design efforts for multiple flight programs with its capacity for rapid six-degrees-of-freedom model development. Due to the assembly of various object types into one application, the application is applicable across a wide variety of launch range problem domains.

More particularly, it is a multi-port, binary computer memory for interfacing with a plurality of computers. There are a plurality of storage cells for containing bits of binary information, the storage cells being disposed at the intersections of a plurality of row conductors and a plurality of column conductors. There is interfacing logic for receiving information from the computers directing access to ones of the storage cells. There are first light sources associated with the interfacing logic for transmitting a first light beam with the access information modulated thereon. First light detectors are associated with the storage cells for receiving the first light beam, for generating an electrical signal containing the access information, and for conducting the electrical signal to the one of the storage cells to which it is directed. There are holographic optical elements for reflecting the first light beam from the first light sources to the first light detectors.

    Port-wine stains (PWS) are bluish red skin stains that are caused by enlarged, ectatic blood vessels in the dermis. Laser treatment of PWS is analyzed from computation of the spatial distribution of heat production by direct absorption of the laser light and subsequent heat conduction. The absorption and scattering caused by oxyhemoglobin, epidermis, and dermis as a function of wavelength are utilized in this analysis. Ideal treatment is defined as coagulating the ectatic blood vessels without irreversible damage to the epidermis and dermis. The analysis shows that a millisecond pulsed, yellow dye laser at 577 nm (one of the large absorption bands in blood) is the laser of choice to treat PWS, offering as close to the ''ideal treatment'' as possible. The blue-green argon laser, which is currently the most frequently used laser for this purpose, is strongly recommended with irradiation times in milliseconds. Other lasers that are in clinical use, such as the red ruby and near-infrared Nd-YAG lasers, can provide selective treatment only when the epidermis is cooled concurrently. The CO/sub 2/ laser, on the other hand, can coagulate the blood vessels only through heat conduction from the hot epidermis; hence, it has neither the treatment selectivity nor any other physical option to force this selectivity.

The internal aerodynamic performance characteristics of the cruise, transition, and vertical lift modes are considered for four ventral nozzle types. The nozzle configurations examined include those with: butterfly-type inner doors and vectoring exit vanes; circumferential inner doors and thrust vectoring vanes; a three-port segmented version with circumferential inner doors; and a two-port segmented version with cylindrical nozzle exit shells. During the testing, internal and external pressure is measured, and the thrust and flow coefficients and resultant vector angles are obtained. The inner door used for ventral nozzle flow control is found to affect performance negatively during the initial phase of transition. The best thrust performance is demonstrated by the two-port segmented ventral nozzle due to the elimination of the inner door.

  16. Self-regulating fuel staging port for turbine combustor

    DOEpatents

    Van Nieuwenhuizen, William F.; Fox, Timothy A.; Williams, Steven

    2014-07-08

    A port (60) for axially staging fuel and air into a combustion gas flow path 28 of a turbine combustor (10A). A port enclosure (63) forms an air path through a combustor wall (30). Fuel injectors (64) in the enclosure provide convergent fuel streams (72) that oppose each other, thus converting velocity pressure to static pressure. This forms a flow stagnation zone (74) that acts as a valve on airflow (40, 41) through the port, in which the air outflow (41) is inversely proportion to the fuel flow (25). The fuel flow rate is controlled (65) in proportion to engine load. At high loads, more fuel and less air flow through the port, making more air available to the premixing assemblies (36).

    2004-06-29

    Most visualizations of security-related network data require large amounts of finely detailed, high-dimensional data. However, in some cases, the data available can only be coarsely detailed because of security concerns or other limitations. How can interesting security events still be discovered in data that lacks important details, such as IP addresses, network security alarms, and labels? In this paper, we discuss a system we have designed that takes very coarsely detailed data-basic, summarized information of the activity on each TCP port during each given hour-and uses visualization to help uncover interesting security events.

    Sediment core was collected from Labuan port and analyzed to determine the radioactivity of thorium (Th) isotopes. The objectives of this study are to determine the possible sources of Th isotopes at Labuan port and estimates the sedimentation rate based on {sup 228}Th/{sup 232}Th model. The results suggest the {sup 230}Th and {sup 232}Th might be originated from terrestrial sedimentary rock while {sup 228}Th originated by authigenic origin. High ratio value of {sup 230}Th/{sup 232}Th detected at the top surface sediment indicates the increasing of {sup 230}Th at the recent years which might be contributed from the anthropogenic sources. The sedimentation rate of core sediment from Labuan Port was successfully estimated by using {sup 228}Th/{sup 232}Th model. The result show high sedimentation rate with 4.67 cm/year indicates rapid deposition occurred at this study area due to the high physical activity at the Labuan port. By assume the constant sedimentation rate at this area; we estimated the age of 142 cm core sediment obtained from Labuan port is 32 years started from 1981 to 2012. This chronology will be used in forthcoming research to investigate the historical profile of anthropogenic activities affecting the Labuan port.

    The Lunar Electric Rover (LER), formerly called the Small Pressurized Rover (SPR), is currently being carried as an integral part of the current Lunar Surface Architectures under consideration in the Constellation program. One element of the LER is the suit port, the means by which the crew performs Extravehicular Activities (EVAs). Two suit port deliverables were produced in fiscal year 2008: an aft bulkhead mockup for functional integrated testing with the 1-G LER mockup and a functional and pressurizable Engineering Unit (EU). This paper focuses on the aft bulkhead mockup test results from Desert Research and Technology Studies (D-RATS) October 2008 testing at Black Point Lava Flow (BPLF), Arizona. Refer to 39th International Conference on Environmental Systems (ICES) for test results of the EU. The suit port aft bulkhead mockup was integrated with the mockup of the LER cabin and chassis. It is located on the aft bulkhead of the LER cabin structure and includes hatches, a locking mechanism, seals, interior and exterior suit don/doff aids, and exterior platforms to accommodate different crewmember heights. A lightweight mockup of the Mark III suit was tested with the suit port aft bulkhead mockup. There are several limitations to the suit port and mockup suits, and results of the suit port evaluation are presented and interpreted within the context of the limitations.

    The progressive increase in world population has become a most urgent global problem in recent years. Man has, however, been interested in controlling his reproductivity at the family level for many centuries. Historical aspects of this saga are reviewed. The modern era of conception control was ushered in by Makepeace et al. in 1937 when ovulation inhibition by progesterone was demonstrated. Confirmation of this by Pincus and associates, and development of the potent oral progestational agents, the 19-norsteroids, have made efficient reliable contraception a reality. Experience with one of these agents (Ortho-Novum, 2 mg.) in 115 patients through 805 cycles is presented. Conception control was 100% effective at this dosage. Side effects were minimal. Only three of the women discontinued the tablets because of these effects. All but five in this group of 115 preferred the oral contraceptives to methods previously employed. PMID:13973987

  13. The submarine river of Port Miou (France), A karstic system inherited from the Messinian deep stage

    NASA Astrophysics Data System (ADS)

    Cavalera, T.; Gilli, E.

    2009-04-01

    The Port Miou system (Cassis, France) is a two kilometers long submarine gallery that extends in the limestone series of Calanques (Marseille, France). The average discharge is between 2 to 5 m3/s but the water is brackish and cannot be used for water supply. In the 1970s, a dam was built to prevent saltwater intrusion in the cave but these experimental attempts did not succeed in getting rid of the residual salinity which remained near 3 g l-1 upstream the dam. The use of helium and later rebreathers by cave divers made possible the exploration of a vertical pit down to 179 m below the sea level. At that depth, the water is still brackish. The cave extends further and deeper but the exploration is limited by the present diving technology. The canyon of Cassidaigne is located a few kilometers south from Port Miou. It cuts the continental shelf where bathymetric studies have shown the presence of dolines. Caves and speleothems have been observed during submarine explorations on the walls of the canyon. This canyon is not connected to a continental valley and it is assumed that it is a pocket valley. Its presence is related to the several lowering stages of the Mediterranean Sea during the Messinian Salinity Crisis. We suggest that during the important drop of sea level of the Mediterranean, the underground river of Port-Miou, flowed several hundreds meters below its current position, and excavated the canyon. At the end of the Messinian crisis, the system was flooded by seawater. The karst water now flows through an upper gallery but the presence of a paleo-drain filled by seawater makes possible a deep marine intrusion into the karst system. Several geomorphologic clues (bathymetry, submarine valley network…) reinforce the fact that the continental shelf near Marseilles is an important karstic network drowned below the sea level. This model is supported by the observation in Port Miou of an important quantity of titanium at the upper surface of the cave sediment

    Beautiful colour images of the sky are both a blessing and a curse for the communication of astronomy to the public. While undoubtedly attractive, they can obscure the fact that discoveries are often made in astrophysics using techniques and measurements that are much more difficult to grasp and certainly less appealing to view. Should we try to explain such concepts as spectroscopy, polarimetry and interferometry, or is it a lost cause? The most effective approach to this problem may be to lead the audience to ask the question themselves: "But how do you know that?"

    Construction continued last year on the Zeepipe system to take Norwegian North Sea gas to the Belgian port of Zeebrugge. Prominent among the accomplishments of Phase 3 of the project was the installation in 1992 of a subsea connection point (SCP) at the hydraulic mid-point of the system between Sleipner field and the Zeebrugge terminal. The SCP provides for new branches to be connected to the original 40-in. trunkline during future phases without the pipeline being shutdown. The paper describes Zeepipe's options; the adopted solution; pipeline expansion; the subframe, main unit, and supports; U-bend cover and pipe supports; the installation; and tie-ins.

  1. Concepts and Relations in Neurally Inspired In Situ Concept-Based Computing

    PubMed Central

    van der Velde, Frank

    2016-01-01

    In situ concept-based computing is based on the notion that conceptual representations in the human brain are “in situ.” In this way, they are grounded in perception and action. Examples are neuronal assemblies, whose connection structures develop over time and are distributed over different brain areas. In situ concepts representations cannot be copied or duplicated because that will disrupt their connection structure, and thus the meaning of these concepts. Higher-level cognitive processes, as found in language and reasoning, can be performed with in situ concepts by embedding them in specialized neurally inspired “blackboards.” The interactions between the in situ concepts and the blackboards form the basis for in situ concept computing architectures. In these architectures, memory (concepts) and processing are interwoven, in contrast with the separation between memory and processing found in Von Neumann architectures. Because the further development of Von Neumann computing (more, faster, yet power limited) is questionable, in situ concept computing might be an alternative for concept-based computing. In situ concept computing will be illustrated with a recently developed BABI reasoning task. Neurorobotics can play an important role in the development of in situ concept computing because of the development of in situ concept representations derived in scenarios as needed for reasoning tasks. Neurorobotics would also benefit from power limited and in situ concept computing. PMID:27242504

    Porting is a powerful methodology to recalibrate an existing database of ion chromatography (IC) retention times by reflecting the changes of column behavior resulting from either batch-to-batch variability in the production of the column or the manufacture of new versions of a column. This approach has been employed to update extensive databases of retention data of inorganic and organic anions forming part of the "Virtual Column" software marketed by Thermo Fisher Scientific, which is the only available commercial optimization tool for IC separation. The current porting process is accomplished by performing three isocratic separations with two representative analyte ions in order to derive a porting equation which expresses the relationship between old and new data. Although the accuracy of retention prediction is generally enhanced on new columns, errors were observed on some columns. In this work, the porting methodology was modified in order to address this issue, where the porting equation is now derived by using six representative analyte ions (chloride, bromide, iodide, perchlorate, sulfate, and thiosulfate). Additionally, the updated porting methodology has been applied on three Thermo Fisher Scientific columns (AS20, AS19, and AS11HC). The proposed approach showed that the new porting methodology can provide more accurate and robust retention prediction on a wide range of columns, where average errors in retention times for ten test anions under three eluent conditions were less than 1.5%. Moreover, the retention prediction using this new approach provided an acceptable level of accuracy on a used column exhibiting changes in ion-exchange capacity. PMID:26860051

  3. Transumbilical Retrieval of Surgical Specimens Through a Multichannel Port

    Ju, Da Hye; Lee, Sang Soo; Sohn, Woo Seok

    2014-01-01

    Background: Laparoscopic surgery is often used to excise adnexal masses; however, the retrieval of specimens such as large cystic masses through conventional 5- or 10-mm ports is difficult and time-consuming. We compared outcomes between conventional laparoscopic surgery for adnexal masses and transumbilical specimen retrieval through a multichannel port during single- or 2-port laparoscopy. Methods: A total of 341 patients who underwent laparoscopic surgery for adnexal masses from November 2006 to December 2010 were included. The patients were divided into 2 groups: group I consisted of 249 patients who underwent conventional laparoscopy, and group II consisted of 92 patients who underwent single- or 2-port laparoscopy using a multichannel port. The clinical characteristics and operative outcomes of the 2 groups were compared. Results: The mean operation time was 51.8 ± 21.5 minutes in group I and 57.2 ± 23.9 minutes in group II. The mean specimen retrieval time was longer in group I (2.9 ± 4.0 minutes) than in group II (2.2 ± 1.8 minutes). Endoscopic bag rupture during specimen retrieval occurred in 11 patients in group I and in no patients in group II. Conclusions: The transumbilical retrieval of surgical specimens through a multichannel port with a wound retractor was safe and did not result in leakage of the cystic contents. This technique reduced the specimen retrieval time, especially for large masses. However, the mean operation time was not shortened with this procedure, because of the learning period and the time required to prepare the umbilical multichannel port. PMID:25408603

  6. Forecasting Container Throughput at the Doraleh Port in Djibouti through Time Series Analysis

    NASA Astrophysics Data System (ADS)

    Mohamed Ismael, Hawa; Vandyck, George Kobina

    The Doraleh Container Terminal (DCT) located in Djibouti has been noted as the most technologically advanced container terminal on the African continent. DCT's strategic location at the crossroads of the main shipping lanes connecting Asia, Africa and Europe put it in a unique position to provide important shipping services to vessels plying that route. This paper aims to forecast container throughput through the Doraleh Container Port in Djibouti by Time Series Analysis. A selection of univariate forecasting models has been used, namely Triple Exponential Smoothing Model, Grey Model and Linear Regression Model. By utilizing the above three models and their combination, the forecast of container throughput through the Doraleh port was realized. A comparison of the different forecasting results of the three models, in addition to the combination forecast is then undertaken, based on commonly used evaluation criteria Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE). The study found that the Linear Regression forecasting Model was the best prediction method for forecasting the container throughput, since its forecast error was the least. Based on the regression model, a ten (10) year forecast for container throughput at DCT has been made.

    The Patos Lagoon estuary is a reservoir of fine sediments derived from the continental basin, which is exported to the coastal area through a narrow channel with average discharge of 2000 m3 s-1. The Port of Rio Grande is located in this connection channel between the Patos Lagoon and the Atlantic Ocean, and recently received investments from the Brazilian Government to expand its draft and modify the configuration of the breakwaters located at the mouth. The objective of this study is to investigate changes in the fine sediment dynamics in the estuarine and coastal region, after the modernization work carried out at the Port of Rio Grande. The study was conducted using a three-dimensional numerical model (TELEMAC-3D) coupled with a sediment in suspension and morphological model (SediMorph). Results were analyzed in a comparative way in relation to the deposition pattern observed in these regions before and after the construction work. Results indicate that there was a change in the deposition pattern and redistribution of sediment at the bottom due to hydrodynamic changes resulting from the new configuration of the breakwaters and progressive deepening of the access channel.

    Background From 2003 to 2008, 25 cross-sector, multidisciplinary community partnerships funded through the Active Living by Design (ALbD) national program designed, planned, and implemented policy and environmental changes, with complementary programs and promotions. This paper describes the use of concept-mapping methods to gain insights into promising active living intervention strategies based on the collective experience of community representatives implementing ALbD initiatives. Methods Using Concept Systems software, community representatives (n=43) anonymously generated actions and changes in their communities to support active living (183 original statements, 79 condensed statements). Next, respondents (n=26, from 23 partnerships) sorted the 79 statements into self-created categories, or active living intervention approaches. Respondents then rated statements based on their perceptions of the most important strategies for creating community changes (n=25, from 22 partnerships) and increasing community rates of physical activity (n=23, from 20 partnerships). Cluster analysis and multidimensional scaling were used to describe data patterns. Results ALbD community partnerships identified three active living intervention approaches with the greatest perceived importance to create community change and increase population levels of physical activity: changes to the built and natural environment, partnership and collaboration efforts, and land-use and transportation policies. The relative importance of intervention approaches varied according to subgroups of partnerships working with different populations. Conclusions Decision makers, practitioners, and community residents can incorporate what has been learned from the 25 community partnerships to prioritize active living policy, physical project, promotional, and programmatic strategies for work in different populations and settings.

    The progress of economic globalization, the rapid growth of international trade, and the maritime transportation has played an increasingly significant role in the international supply chain. As a result, worldwide seaports have suffered from a central problem, which appears in the form of massive amounts of fuel consumed and exhaust gas fumes emitted from the ships while berthed. Many ports have taken the necessary precautions to overcome this problem, while others still suffer due to the presence of technical and financial constraints. In this paper, the barriers, interconnection standards, rules, regulations, power sources, and economic and environmental analysis related to ships, shore-side power were studied in efforts to find a solution to overcome his problem. As a case study, this paper investigates the practicability, costs and benefits of switching from onboard ship auxiliary engines to shore-side power connection for high-speed crafts called Alkahera while berthed at the port of Safaga, Egypt. The results provide the national electricity grid concept as the best economical selection with 49.03 percent of annual cost saving. Moreover, environmentally, it could achieve an annual reduction in exhaust gas emissions of CO2, CO, NO x , P.M, and SO2 by 276, 2.32, 18.87, 0.825 and 3.84 tons, respectively.

    Purpose. With many preterm babies now surviving as a result of improvement in neonatal care in Nigeria, the incidence of visual impairment/blindness as a result of retinopathy of prematurity (ROP) may rise. We describe our findings after screening starts for the first time in a 15-year-old special care baby unit so as to establish the incidence and risk factors for developing ROP. Methods. A prospective study carried out at the Special Care Baby Unit (SCBU) and Pediatric Outpatient Clinics of the University of Port Harcourt Teaching Hospital between January 1 and October 31, 2012. Fifty-three preterm babies (of 550 neonates admitted within the study period) delivered before 32 completed weeks and weighing less than 1500 g were included in the study following informed consent and the main outcome measure was the development of any stage of ROP. Results. Mean gestational age at birth was 28.98 ± 1.38 weeks. Mean birth weight was 1411 ± 128 g. Out of 550 babies admitted at SCBU, 87 of 100 preterms survived with 53 included in study. Twenty-five (47.2%) had different degrees of ROP with prevalence found to be 47.2%. Prevalence was higher (75%) in babies weighing <1300 g and those delivered before 30-week gestation (58%). Twenty-one (84%) had stage 1 no plus disease and 3 (12%) had stage 2 no plus disease. Only 1 (4%) had threshold disease in Zone 1. None had disease at stage 4 or 5 or AP-ROP. Receiving supplemental oxygen (χ (2) = 6.17; P = 0.01), presence of sepsis (χ (2) = 7.47; P = 0.006), multiple blood transfusions (χ (2) = 5.11; P = 0.02), and delivery by caesarian section (χ (2) = 4.22; P = 0.04) were significantly associated with development of ROP. There were no significant differences with gender, apneic spells, jaundice, or phototherapy. Conclusions and Relevance. All live infants with ROP were noted to regress spontaneously in this study. Though it may not be cost effective to acquire treatment facilities at the moment (the only child with

  14. Single port/incision laparoscopic surgery compared with standard three-port laparoscopic surgery for appendicectomy - a randomised controlled trial

    PubMed Central

    2012-01-01

    Background Laparoscopic surgery has become the preferred approach for many procedures because of reduced post-operative pain, better recovery, shorter hospital stay and improved cosmesis. Single incision laparoscopic surgery is one of the many recent variants where either standard ports or a specially designed single multi-channel port is introduced through a single skin incision. While the cosmetic advantage of this is obvious, the evidence base for claims of reduced morbidity and better post-operative recovery is weak. This study aims to compare the effectiveness of single port/incision laparoscopic appendicectomy with standard three-port laparoscopic appendicectomy in adult patients at six weeks post-surgery. We also wish to assess the feasibility of a multicentre randomised controlled trial comparing single port/incision laparoscopic surgery with standard three-port laparoscopic surgery for other surgical techniques. Methods and design Patients diagnosed with suspected appendicitis and requiring surgical treatment will be randomised to receive either standard three-port or single incision laparoscopic surgery. Data will be collected from clinical notes, operation notes and patient reported questionnaires. The following outcomes will be considered: 1. Effectiveness of the surgical procedure in terms of: •patient reported outcomes •clinical outcomes •resource use 2. Feasibility of conducting a randomised controlled trial (RCT) in the emergency surgical setting by quantifying: •patient eligibility •randomisation acceptability •feasibility of blinding participants to the intervention received •completion rates of case report forms and patient reported questionnaires Trial registration ISRCTN66443895 (assigned 10 March 2011, first patient randomised 09 January 2011) PMID:23111090

    Single-port video-assisted thoracoscopic surgery (VATS) has been increasingly applied in clinical settings in the past two years along with the improvements in both endoscopic instruments and surgical skills. Our center began to perform single-port VATS lobectomy in May 2014 and had performed this procedure in 121 patients till January 2015. The surgical incision (3.5-4.5 cm in length) was created in the 4th or 5th intercostal space at the anterior axillary line at the diseased side. The operator standed at the abdominal side of the patient and operated using the endoscopic instruments only. The surgical steps of single-port VATS lobectomy were same as those of the triple-port VATS lobectomy. There was no fixed mode in handling the three major structures of the pulmonary lobes, and the resection sequence can be scheduled based on the development status of pulmonary fissures and on the difficulties in dissecting the relevant structures. We believe the single-port VATS lobectomy is a safe and feasible procedure and warrants further clinical applications after finishing these surgeries. PMID:26207236

    Two experimental monitoring campaigns were carried out in 2012 to investigate the air quality in the port of Naples, the most important in southern Italy for traffic of passengers and one of the most important for goods. Therefore, it represents an important air pollution source located close to the city of Naples. The concentrations of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and BTEX (benzene, toluene, ethylbenzene, and xylenes) in the air were measured at 15 points inside the Naples port area through the use of passive samplers. In addition, a mobile laboratory was positioned in a fixed point inside the port area to measure continuous concentration of pollutants together with particulate matter, ambient parameters, and wind direction and intensity. The pollution levels monitored were compared with those observed in the urban area of Naples and in other Mediterranean ports. Even though the observation time was limited, measured concentrations were also compared with limit values established by European legislation. All the measured pollutants were below the limits with the exception of nitrogen dioxide: its average concentration during the exposition time exceeded the yearly limit value. A spatial analysis of data, according to the measured wind direction and intensity, provided information about the effects that ship emissions have on ambient air quality in the port area. The main evidence indicates that ship emissions influence sulfur dioxide concentration more than any other pollutants analyzed. PMID:26029862

    The restructuring of production resulting from the Port Modernization Law (Law 8.630/90) caused significant changes in work organization of Brazilian Ports. In the case of Mucuripe (Fortaleza, Ceará), in particular, the changes were very intense as Mucuripe is an old port that, before the Law, had labor regulation being governed by Trade Unions. This paper aims to present the perceptions of Union Representatives on the changes brought about by the Law on work organization in the port of Fortaleza, its influence in the organization and in the way the Unions deal with this new reality. Open and exploratory interviews were conducted with representatives of occasional labor workers registered in the Port of Fortaleza OGMO (Orgão Gestor de Mão de Obra, Labor Regulation Management). The analysis of the collected material in the interviews was based on the technique of content analysis proposed by Bardin (1979). Trade Unions have undergone a great loss of power and it has reflected in a relative inability to perform its function and to fight for the rights of the workers. The obvious Trade Unions weakness - a reduction of strikes and less unionized workers - reflects the dominating ideology of capital. PMID:22317684

    Background and Objectives: Robotic-assisted laparoscopic surgery is increasingly used for the management of patients with gynecologic malignancies. The rate of port-site metastases in patients undergoing these procedures is unknown. Methods: We conducted a retrospective cohort analysis of a prospective database. A total of 220 women underwent robotic-assisted surgery from 2007 through 2011. Malignancy was detected in 145 cases, and 142 met the inclusion criteria with histologically proven cancer and robotically completed surgery. All women who underwent surgical treatment for their malignancies were followed up at the study site for oncology treatments. Results: There were 710 potential port sites for metastasis. We found that 2 of 142 patients each had a single port-site metastasis, for an overall rate of 1.41%, or 0.28% per trocar site. Recurrent disease was not isolated in the two patients found to have port-site metastases because both had concurrent sites of pelvic recurrence. Conclusion: The rate of port-site metastases in patients undergoing robotic-assisted laparoscopic surgery for gynecologic malignancies is similar to the published rate in the literature for traditional laparoscopic oncology.

    Through a brilliant medical way, Charcot was, at the same time, rheumatologist, geriatric, clinician, pathologist - and mainly neuro-pathologist - ending as a psychiatrist (according to todays medical terminology). Here, we will point out how much scientific theory and philosophy may support an original concept very unusual during the second half of XIXth century medicine. Describing connection between biology and medicine according to Auguste Comte thoughte, the author is thoroughly going into the course introduced by Charcot: scientific medicine instead of empirical one; structural medical-anatomy against rudimentary approach and rising of experimental medicine; impact of human sciences on medical knowledge; appearance of specialists near general practitioners; idea of organic disturbances denying any 'faith healing". In fact, Charcot asserts that bedside instruction prevails against accurate sciences. PMID:11640482

    Jumper connectors are used in the Hanford site for remotely connecting jumper pipe lines in the radioactive zones. The jumper pipes are used for transporting radioactive fluids and hazardous chemicals. This report evaluates the adequacy and the integrity of the 2-, 3-, and 4-in. single-port integral seal block (ISB) jumper connector assemblies, as well as the three-way 2-in. configuration. The evaluation considers limiting forces from the piping to the nozzle. A stress evaluation of the jumper components (hook, hook pin, operating screw, nozzle and nozzle flange, and block) under operational (pressure, thermal, dead weight, and axial torquing of the jumper) and seismic loading is addressed in the report.

    1987-01-01

    An investigation has been conducted to evaluate the effects of several geometric parameters on the internal performance of rectangular thrust-reverser ports for nonaxisymmetric nozzles. Internal geometry was varied with a test apparatus which simulated a forward-flight nozzle with a single, fully deployed reverser port. The test apparatus was designed to simulate thrust reversal (conceptually) either in the convergent section of the nozzle or in the constant-area duct just upstream of the nozzle. The main geometric parameters investigated were port angle, port corner radius, port location, and internal flow blocker angle. For all reverser port geometries, the port opening had an aspect ratio (throat width to throat height) of 6.1 and had a constant passage area from the geometric port throat to the exit. Reverser-port internal performance and thrust-vector angles computed from force-balance measurements are presented.

    "Connectivity thinking" and related concepts have a long history in geomorphology. Since the beginning of the 21st century connectivity research experienced a huge boom in geomorphology as geomorphologists started to develop new concepts on connectivity to better understand the complexity of geomorphic systems and system response to change. However, progress in the field of connectivity in geomorphology has mostly been developing in a parallel manner, resulting in a multiplicity of definitions, concepts and methodological approaches. Nevertheless, a set of common key challenges amongst the different connectivity concepts and approaches used to understand complex geomorphic systems are also evident. In the course of a theory think tank of the COST Action ES1306 (CONNECTEUR - Connecting European Connectivity Research) the following five different key challenges were detected (Turnbull et al., in prep.): (i) defining the fundamental unit, (ii) distinguishing between structural and functional boundaries, (iii) emergent behavior, (iv) memory effects, (v) measuring connectivity. In this presentation we will a) discuss how these key challenges are addressed and approached in connectivity research in geomorphology, b) evaluate ways in which cross-disciplinary advances may be made by exploring potential for a common toolbox approach to the study of connectivity.

    The concept of mixed connective tissue disease (MCTD) as a separate connective tissue disease (CTD) has persisted for more than four decades. High titers of antibodies targeting the U1 small nuclear ribonucleoprotein particle (U1 snRNP) in peripheral blood are a sine qua non for the diagnosis of MCTD, in addition to distinct clinical features including Raynaud's phenomenon (RP), "puffy hands," arthritis, myositis, pleuritis, pericarditis, interstitial lung disease (ILD), and pulmonary hypertension (PH). Recently, population-based epidemiology data from Norway estimated the point prevalence of adult-onset MCTD to be 3.8 per 100,000 and the mean annual incidence to be 2.1 per million per year, supporting the notion that MCTD is the least common CTD. Little is known about the etiology of MCTD, but recent genetic studies have confirmed that MCTD is a strongly HLA (​human leukocyte antigen)-linked disease, as the HLA profiles of MCTD differ distinctly from the corresponding profiles of ethnically matched healthy controls and other CTDs. In the first section of this review, we provide an update on the clinical, immunological, and genetic features of MCTD and discuss the relationship between MCTD and the other CTDs. Then we proceed to discuss the recent advances in therapy and our current understanding of prognosis and prognostic factors, especially those that are associated with the more serious pulmonary and cardiovascular complications of the disease. In the final section, we discuss some of the key, unresolved questions related to anti-RNP-associated diseases and indicate how these questions may be approached in future studies. PMID:27421219

    The purpose of this study is to develop a rodent functional magnetic resonance imaging (fMRI) survival model with the use of heparin-coated vascular access devices. Such a model would ease the administration of sedative agents, reduce the number of animals required in a survival experiment, and eliminate animal-to-animal variability seen in previous designs. Seven male Sprague-Dawley rats underwent surgical placement of an MRI-compatible vascular access port, followed by implantable electrode placement on the right median nerve. Functional MRI during nerve stimulation and resting-state functional connectivity MRI (fcMRI) were performed at times 0, 2, 4, 8, and 12 weeks postoperatively using a 9.4 T scanner. Anesthesia was maintained using intravenous dexmedetomidine and reversed using atipamezole. There were no fatalities or infectious complications during this study. All vascular access ports remained patent. Blood oxygen level dependent (BOLD) activation by electrical stimulation of the median nerve using implanted electrodes was seen within the forelimb sensory region (S1FL) for all animals at all time points. The number of activated voxels decreased at time points 4 and 8 weeks, returning to a normal level at 12 weeks, which is attributed to scar tissue formation and resolution around the embedded electrode. The applications of this experiment extend far beyond the scope of peripheral nerve experimentation. These vascular access ports can be applied to any survival MRI study requiring repeated medication administration, intravenous contrast, or blood sampling. PMID:21726581

    1995-01-01

    Current Connection Machine (CM) Fortran codes developed for the CM-2 and the CM-5 represent an important class of parallel applications. Several users have employed CM Fortran codes in production mode on the CM-2 and the CM-5 for the last five to six years, constituting a heavy investment in terms of cost and time. With Thinking Machines Corporation's decision to withdraw from the hardware business and with the decommissioning of many CM-2 and CM-5 machines, the best way to protect the substantial investment in CM Fortran codes is to port the codes to High Performance Fortran (HPF) on highly parallel systems. HPF is very similar to CM Fortran and thus represents a natural transition. Conversion issues involved in porting CM Fortran codes on the CM-5 to HPF are presented. In particular, the differences between data distribution directives and the CM Fortran Utility Routines Library, as well as the equivalent functionality in the HPF Library are discussed. Several CM Fortran codes (Cannon algorithm for matrix-matrix multiplication, Linear solver Ax=b, 1-D convolution for 2-D datasets, Laplace's Equation solver, and Direct Simulation Monte Carlo (DSMC) codes have been ported to Subset HPF on the IBM SP2 and the SGI Power Challenge. Speedup ratios versus number of processors for the Linear solver and DSMC code are presented.

    While polluted sediments present a threat to the health of the marine ecosystem and indirectly to the public health, ammunition dump sites being mostly unprotected and neglected, present a serious threat to human security, environmental security and could be possible objects of misuse. Of special interest are sediments in ports and marinas. Those are the places where any suspicious object needs to be analyzed for the presence of explosives and CW. After analyzing several hundreds of sediment samples collected along the Adriatic coast, it has been found that they could be grouped in 7 categories: bays, beaches, villages, ports, marinas - pier area, marina - service areas and others. We have shown that the sediments in ports and harbors contain increased values of elements present in antifouling paints (Cu, As, Zn and Pb). Their presence modifies the response of survey probes while screening the sea floor for the presence of explosives and CW.

    The development and maintenance of the infrastructure, facilities, logistics and other assets of the Port of Rotterdam requires a broad spectrum of heterogeneous information. This information concerns features, which are spatially distributed above ground, underground, in the air and in the water. The data are managed in a variety of data models with varying levels of dimensionality, granularity, accuracy and up-to-dateness. Additionally increasing number of 3D design models is becoming available. This complexity of tasks and diversity of information challenges the Port authority to look for more advanced 3D solutions. This paper presents research in progress related to developing a 3D SII in support of information and process management within the Port of Rotterdam.

    An encapsulated grating with a metal slab is designed as a reflection three-port beam splitter at the wavelength of 1550 nm under normal incidence. Such a new grating is aimed to separate energies into the ±1st and the 0th orders for both TE and TM polarizations. The grating parameters such as grating period, duty cycle and grating depth are optimized by using rigorous coupled-wave analysis. Based on optimized grating parameters, efficiencies can reach more than 32% with the polarization-independent property. It indicates that reflection three-port beam splitter with high efficiency can be obtained by the encapsulated grating. Moreover, the presented reflection three-port grating has advantages of wide incident wavelength range and angular bandwidth, which would be useful in practical application.

    2014-01-01

    Single-port video-assisted thoracic surgery (VATS) has slowly established itself as an alternate surgical approach for the treatment of an increasingly wide range of thoracic conditions. The potential benefits of fewer surgical incisions, better cosmesis, and less postoperative pain and paraesthesia have led to the technique’s popularity worldwide. The limited single small incision through which the surgeon has to operate poses challenges that are slowly being addressed by improvements in instrument design. Of note, instruments and video-camera systems that are narrower and angulated have made single-port VATS major lung resection easier to perform and learn. In the future, we may see the development of subcostal or embryonic natural orifice translumenal endoscopic surgery access, evolution in anaesthesia strategies, and cross-discipline imaging-assisted lesion localization for single-port VATS procedures.

    1995-01-01

    In personal satellite communications, satellite antenna beam becomes narrow, and number of beams will be thirty to more than one hundred. This paper shows that Multi Port Amplifier is most suitable to multiple beam transmitter for personal communications satellite. It was shown that the single beam coverage area(cell) diameter is determined by personal earth station(PES) eirp, uplink C/No and uplink frequency band. Required number of cells for European or North American regional coverage at FPLMTS uplink frequency band is shown as around 32. It was shown that 32 beams systems will be easily implemented by using 2 set of 16-port MPA. Redundancy to SSPA failure is considered by increasing number of SSPAs. Actual configuration for 16-port MPA are briefly shown. The presented configuration will be easy to implement and the most economical solution.

    We propose a three-port silicon mode-(de)interleaver (TSMIL) using an asymmetric multi-arm Y-junction to flexibly address optical modes and efficiently increase the ports with less cascaded stages in mode-division multiplexing transmission. The design criteria developed for multi-port mode-(de)interleaving is presented. The qualitative functionality of the device is mainly determined by the widths of the arms. The example of a six-mode TSMIL is designed and analyzed in detail. Numerical simulations show that a low excess loss (<1 dB) and a low mode crosstalk (<-17 dB) over a 60 nm wavelength range can be obtained.

  15. Single Port Electro-Thermal Propulsion—Performance Factors

    NASA Astrophysics Data System (ADS)

    Johansen, Donald G.

    2008-04-01

    Performance models for single port ETP (Electro-Thermal Propulsion) devices are presented considering all significant efficiency factors. Single-port ETP devices, which use the nozzle exit as entrance port for beamed power, are capable of high efficiency and high thrust with low mass penalty for both propellant and structure. Previously considered parabolic nozzle shapes have operated in pulse mode to exchange energy at a concentrated focal region, resulting in low efficiency. The proposed cone/bell shape diffuses the focal region prior to chamber entry to allow continuous combustion inside the chamber with high efficiency. Mechanical and thermal limits are evaluated. For vacuum operation, low chamber pressure operation is possible. Thin wall thruster construction results in low chamber and nozzle mass. Further, at low pressure, regenerative cooling is needed only for the chamber and throat region with radiation cooling for the nozzle exit region. These factors permit high expansion ratio and thrust-to-weight ratio needed for performance.

  16. Estimating time-dependent connectivity in marine systems

    2016-02-01

    Hydrodynamic connectivity describes the sources and destinations of water parcels within a domain over a given time. When combined with biological models, it can be a powerful concept to explain the patterns of constituent dispersal within marine ecosystems. However, providing connectivity metrics for a given domain is a three-dimensional problem: two dimensions in space to define the sources and destinations and a time dimension to evaluate connectivity at varying temporal scales. If the time scale of interest is not predefined, then a general approach is required to describe connectivity over different time scales. For this purpose, we have introduced the concept of a "retention clock" that highlights the change in connectivity through time. Using the example of connectivity between protected areas within Barnegat Bay, New Jersey, we show that a retention clock matrix is an informative tool for multitemporal analysis of connectivity.

    This short survey the reviews recent literature on brain connectivity studies. It encompasses all forms of static and dynamic connectivity whether anatomical, functional, or effective. The last decade has seen an ever increasing number of studies devoted to deduce functional or effective connectivity, mostly from functional neuroimaging experiments. Resting state conditions have become a dominant experimental paradigm, and a number of resting state networks, among them the prominent default mode network, have been identified. Graphical models represent a convenient vehicle to formalize experimental findings and to closely and quantitatively characterize the various networks identified. Underlying these abstract concepts are anatomical networks, the so-called connectome, which can be investigated by functional imaging techniques as well. Future studies have to bridge the gap between anatomical neuronal connections and related functional or effective connectivities. PMID:23097663

    'Geometry and Algebra: Glow with the Flow' is the second of five programs in the 2000-2001 NASA CONNECT series. Produced by NASA Langley Research Center's Office of Education, NASA CONNECT is an award-winning series of instructional programs designed to enhance the teaching of math, science and technology in grades 5-8. NASA CONNECT establishes teh 'connection' between the mathematics, science, and tehcnology concepts taught in the classroom and NASA research. NASA CONNECT is FREE and the programs in the series are in the public domain. Visit our web site adn register http://connect.larc.nasa.gov In 'Geometry and Algebra: Glow with the Flow', students will learn about the force of drag and how NASA engineers use models and glowing paints to see how air flows over vehicles in a wind tunnel. Students will also discover how the blended wing body(BWB), a concept super jumbo jet that resembles a flying wing, will affect air travelers of the future. Students will observe NASA engineers using geometry and algebra when they measure and design models to be tested in wind tunnels. By conducting classroom and on-line activities, students will make connections between NASA research and the mathematics, science and technology they learn in their classroom.

    An assembly design system is an important part of computer-aided design systems, which are important tools for realizing product concept design. The traditional assembly design system does not record the connection information of production on the engineering layer; consequently, the upstream design idea cannot be fully used in the downstream design. An assembly design model based on the relationship of engineering connection is presented. In this model, all nodes are divided into two categories: The component and the connection. Moreover, the product is constructed on the basis of the connection relationship of the components. The model is an And/Or graph and has the ability to record all assembly schemes. This model records only the connection information that has engineering application value in the product design. In addition, this model can significantly reduce the number of combinations, and is very favorable for the assembly sequence planning in the downstream. The system contains a connection knowledge system that can be mapped to the connection node, and the connection knowledge obtained in practice can be returned to the knowledge system. Finally, VC++ 6.0 is used to develop a prototype system called Connect-based Assembly Planning (CAP). The relationship between the CAP system and the commercial assembly design system is also established.

    The feasibility of using a computer-based networked collaborative concept mapping system to measure teamwork skills was studied. A concept map is a node-link-node representation of content, where the nodes represent concepts and links represent relationships between connected concepts. Teamwork processes were examined for a group concept mapping…
