China has >400 ports, is home to 7 of 10 biggest ports in the world and its waterway infrastructure construction has been accelerating over the past years. But the increasing number of ports and ships means increasing emissions, and in turn, increasing impact on local and regional air pollution. This paper presents an overview of the broad field of ship emissions in China and their atmospheric impacts, including topics of ship engine emissions and control, ship emission factors and their measurements, developing of ship emission inventories, shipping and port emissions of the main shipping areas in China, and quantitative contribution of shipping emissions to the local and regional air pollution. There have been an increasing number of studies published on all the above aspects, yet, this review identified some critical research gaps, filling of which is necessary for better control of ship emissions, and for lowering their impacts. In particular, there are very few studies on inland ports and river ships, and there are few national scale ship emission inventories available for China. While advanced method to estimate ship emission based on ship AIS activities makes it now possible to develop high spatial- and temporal-resolution emission inventories, the ship emission factors used in Chinese studies have been based mainly on foreign measurements. Further, the contribution of ship emissions to air pollution in coastal cities, the dispersion of pollution plumes emitted by ships, or the chemical evolution process along the transmission path, have so far not been systematically studied in China.

Chemical-biological-radio-nuclear (CBRN) gas masks are the standard means for protecting the general population from inhalation of toxic industrial compounds (TICs), for example after industrial accidents or terrorist attacks. However, such gas masks would not protect patients on home mechanical ventilation, as ventilator airflow would bypass the CBRN filter. We therefore evaluated in vivo the safety of adding a standard-issue CBRN filter to the air-outflow port of a home ventilator, as a method for providing TIC protection to such patients. Eight adult patients were included in the study. All had been on stable, chronic ventilation via a tracheostomy for at least 3 months before the study. Each patient was ventilated for a period of 1 hour with a standard-issue CBRN filter canister attached to the air-outflow port of their ventilator. Physiological and airflow measurements were made before, during, and after using the filter, and the patients reported their subjective sensation of ventilation continuously during the trial. For all patients, and throughout the entire study, no deterioration in any of the measured physiological parameters and no changes in measured airflow parameters were detected. All patients felt no subjective difference in the sensation of ventilation with the CBRN filter canister in situ, as compared with ventilation without it. This was true even for those patients who were breathing spontaneously and thus activating the ventilator's trigger/sensitivity function. No technical malfunctions of the ventilators occurred after addition of the CBRN filter canister to the air-outflow ports of the ventilators. A CBRN filter canister can be added to the air-outflow port of chronically ventilated patients, without causing an objective or subjective deterioration in the quality of the patients' mechanical ventilation.

The Full Scale Sector Model Project, which was initiated in 1995 as one of the Seven Large Projects for ITER R&D, has been continued with the joint effort of the ITER Joint Central Team and the Japanese, Russian Federation and United States Home Teams. The fabrication of a full scale 18° toroidal sector, which is composed of two 9° sectors spliced at the port centre, was successfully completed in September 1997 with a dimensional accuracy of +/-3 mm for the total height and total width. Both sectors were shipped to the test site at the Japan Atomic Energy Research Institute and the integration test of the sectors was begun in October 1997. The integration test involves the adjustment of field joints, automatic narrow gap tungsten inert gas welding of field joints with splice plates and inspection of the joints by ultrasonic testing, as required for the initial assembly of the ITER vacuum vessel. This first demonstration of field joint welding and the performance test of the mechanical characteristics were completed in May 1998, and all the results obtained have satisfied the ITER design. In addition to these tests, integration with the midplane port extension fabricated by the Russian Home Team by using a fully remotized welding and cutting system developed by the US Home Team was completed in March 2000. The article describes the progress, achievements and latest status of the R&D activities for the ITER vacuum vessel.

Many, N.

2018-03-01

This study discusses the processes of government to pass the port development plan in Indonesia with the Port of Belawan and its port expansion as the study case. The study uses a descriptive approach by reviewing and analyzing some of relevant literature as the sources. It also reviews and examines the port development theoretical concepts and models giving attention to the international hub port models resulted from the previous studies. The international hub port aspects assessed to be further applied and compared to the actual situation of the Port of Belawan. This process draws the conclusion on which concept and model the port classified, followed by some recommendations concerning the necessary actions to be taken. The results show that: (1) The port planning regulated in port master plan is the guideline and foundation to implement the port development; (2) Spatial and zoning plan regulations are very important in the preparation, planning, and implementation of port development; (3) It has not provided the necessary facilities and criteria of the global hub port model has not been met completely. The port is strategic to be completely developed as the regional hub port to compete with the major ports of neighboring countries. Eventually, this study requires further analysis to examine the economic feasibility of the Port of Belawan in more comprehensive way functioning as an international hub port along with the ongoing development of Kuala Tanjung Port to achieve its ultimate objectives, among other things, the port effectiveness, efficiency, and competitiveness.

The US Navy visits ports on all continents and many islands of the world, many of which are reported to have a high endemicity of human immunodeficiency virus (HIV) infection. The objective of this study was to determine whether visits to foreign ports by active-duty navy personnel were associated with increased risk of HIV infection. The Naval Health Research Center in San Diego, Calif, maintains records of all HIV enzyme-linked immunosorbent assay and Western blot tests given in the navy. This information, along with career histories and ship movement data, was used in a nested case-control design to examine the relationship between visits to the 100 foreign ports most frequently visited by the navy and risk of HIV seroconversion. All visits to a port and total time in each port during the study period were examined. A total of 813 seroconverters were matched to 6993 seronegative active-duty controls by age, race, sex, occupational group, home port, and year of test. Estimated relative risks of seroconversion associated with visits to foreign ports showed no statistically significant excess risk of HIV infection for navy personnel after visits to any foreign port. These results do not imply that an individual's risk of acquisition of HIV would be less in a foreign port if the individual engaged in high-risk activity there. Rather, they imply that despite the mobility of the US Navy and the large variation in HIV seroprevalence rates throughout the world, navy personnel generally do not appear to be acquiring HIV infections abroad.

Home anti-cancer chemotherapy and palliation in the terminal stage were performed for patients with advanced cancer of the digestive system, using a venous port implanted beneath the skin via the subclavian vein. Patients under 75 years of age (5 with esophageal, 61 gastric, 59 colorectal, 5 cholangio, 5 pancreatic, 1 hepatic and 1 ileal cancer) were treated. With two portable balloon pumps, continuous intravenous infusion of 5-FU (300 or 400 mg/body/day) combined low-dose injection of cisplatin (5 mg/body/day) was continued for 10 days, and repeated 3 times for 6 weeks. The response rate was 17.9% in 78 patients according to valuation of the tumor mass. In 119 patients also undergoing a tumor marker evaluation, an effect was seen in 26.1%. No severe side effects such as renal dysfunction or bone marrow suppression were seen, and no special infusion was needed. Therefore, such treatment can be continued for a long time. Use of a venous port should make easy the switchover to HPN and the amelioration of the symptoms of the terminal stage, such as pain, and helps patients cope with the worry. Therefore, the present technique is useful in a series of cancer treatments including surgery, chemotherapy and the amelioration of symptoms.

Large polyps and early carcinomas of the rectum may be excised with transanal endoscopic surgery (TES). Single-port techniques are emerging in the field of colorectal surgery and have been adapted to many colorectal procedures so far. In this article, we aimed to present our initial experience with TES using a single access port with its technical details. Patients undergoing TES using a single access port between July 2010 and January 2013 were included in the study. Patient demographics, operative technique, and both operative and postoperative outcomes were evaluated and presented. A total of 12 patients (ten males) were included in our study. The median age was 63.5 years (50-84), median American Society of Anesthesiologists (ASA) score was 3 (2-4), and median body mass index was 28.8 kg/m(2) (17.4-55.6). Median operating time was 79 min (43-261). Histopathological diagnoses were as follows: tubulovillous adenoma (n = 6), tubular adenoma (n = 4), adenocarcinoma (n = 1), and neuroendocrine tumor (n = 1). Five patients were sent home on the day of surgery and the median postoperative hospital stay was 1 day (0-38). Median estimated blood loss was 22.5 ml (5-150). A transient urinary retention was developed in one patient postoperatively, and two patients had postoperative bleeding. The first of these patients with a long history of anticoagulant usage had rectal bleeding 13 days after surgery, which was successfully managed with medical treatment. The second patient was morbidly obese, had multiple comorbidities, and had rectal bleeding on postoperative day 7 which was managed with local epinephrine injection. He suffered unrelated cardiac death on postoperative day 38. TES is safe and feasible when using a single port and in the standard laparoscopic setting. The single-port technique may play a major role in the widespread utilization of TES as a treatment for large adenomas and early rectal cancers.

Carbon monoxide (CO) poisoning is a notable cause of death at homes and industries that is posing public health problem worldwide that requires an elaborate study. To study and characterize deaths resulting from the noxious gas (CO). A ten year (January 1st, 1995 December 31st 2004) autopsy study. Port Harcourt, Nigeria. Coroners and hospital autopsies performed by the authors at the University of Port Harcourt Teaching Hospital (UPTH), other hospitals and private mortuaries in Port Harcourt on deaths from carbon monoxide poisoning were studied over ten years. The circumstances of death reported by police were accidental, homicidal or suicidal; and other autopsy findings were used for the study. A total of seventy five autopsies were studied; out which 21 (28.0%) were females and 54 (72.0%) males giving a ratio 1:2.6 male dominance. The highest frequency of death 25 (33.3%) occurred in the age group 60 69 years; while the least 3 (4%) occurred in the age group 0 9 years. The youngest was an unborn 7 month old male fetus while the eldest was 85 years old female. The most common was accidental carbon monoxide poisoning which accounted for 48 (64%) cases. While Homicidal CO poisoning .was 24 (32%) and suicidal CO poisoning was 3 (4.0%). Body recovered from fumy electric generator rooms was 46 (61.3%) while least frequency was bodies recovered from naked flame 3 (4%). Carbon monoxide poisoning is posing a serious public health problem when ever it occurs. There is need for public enlightenment about this gas as it is related to fumes from generator, car exhausts, poorly ventilated rooms and enclosed chambers in order to reduce the carnage associated with it both at home and industries.

Temporary vs. Permanent Sub-slab Ports: A Comparative ...

EPA Pesticide Factsheets

Vapor intrusion (VI) is the migration of subsurface vapors, including radon and volatile organic compounds (VOCs), from the subsurface to indoor air. The VI exposure pathway extends from the contaminant source, which can be impacted soil, non-aqueous phase liquid, or contaminated groundwater, to indoor air-exposure points. Therefore, contaminated matrices may include groundwater, soil, soil gas, and indoor air. VOC contaminants of concern typically include halogenated solvents such as trichloroethene, tetrachloroethene, and chloroform, as well as petroleum hydrocarbons, such as the aromatic VOCs benzene, toluene, and xylenes. Radon is a colorless radioactive gas that is released by radioactive decay of radionuclides in rock and soil that migrate into homes through VI in a similar fashion to VOCs. This project focused on the performance of permanent versus temporary sub-slab sampling ports for the determination of VI of halogenated VOCs and radon into an unoccupied house. VOC and radon concentrations measured simultaneously in soil gas using collocated temporary and permanent ports appeared to be independent of the type of port. The variability between collocated temporary and permanent ports was much less than the spatial variability between different locations within a single residential duplex. The agreement of the majority of VOC and radon concentrations, 0–36% relative percent difference, and 2–19% relative standard deviation respectively, of each sub-sl

Retained placenta is associated with an increased risk of maternal morbidity and mortality especially in developing countries. To determine the incidence and evaluate the mode of presentation, risk factors and method of treatment of patients with retained placenta. A retrospective review of retained placenta managed at the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt over a 5 year period (January 2009 to December 2013). Data obtained were analyzed using statistical software SPSS 17.0. There were 93 cases of retained placenta out of 15,789 deliveries, giving an incidence of 0.59%.85 patients' case records were available for analysis. Majority of the patients 69 (81.2%) were unbooked (had no antenatal care) with 60 (70.6%) having home deliveries. Previous history of dilatation and curettage and preterm deliveries, accounted for the major identifiable risk factors at 55 (64.7%) and 22 (25.9%) respectively. At presentation, 22(25.9%) were in hypovolemic shock. Manual removal of the placenta was the commonest treatment modality (87.1%).There was one maternal death giving rise to a case fatality rate of 1.18%. Retained placenta is a major cause of maternal morbidity and mortality from postpartum haemorrhage and other complications related to its removal. The incidence can be reduced by antenatal care, skilled birth attendance and provision of emergency obstetrics care services.

Public health significance of chickenpox on ships - conclusions drawn from a case series in the port of Hamburg.

PubMed

Schlaich, Clara; Riemer, Tobias; Lamshöft, Maike; Hagelstein, Jan-Gerd; Oldenburg, Marcus

2010-01-01

Despite international notification requirements, the magnitude of disease transmission on board ships remains undetermined. This case series aims to exemplify that varicella aboard ships is a topic of interest for maritime medicine and of public health significance. Systematic presentation of cases of chickenpox reported to the Hamburg Port Health Authority between November 2007 and April 2008. A systematic literature search on 'ships and chickenpox' was performed. Five crew cases of chickenpox were reported from two passenger ships and two cargo ships. The cases originated from Indonesia (2), the Philippines (1), and Sri Lanka (2). Three cases were notified by the shipmaster, one by a general practitioner, and one by the immigration service. Sources of infection were other crewmembers, passengers, and persons in the home countries. This description of five varicella cases aboard ships points to the significance of the disease among seafarers. Many seafarers originate from tropical countries where seroconversion to varicella zoster virus generally occurs in late adolescents and adults. Thus, a substantial portion of the crew may be non-immune and have the potential to introduce the disease from their home country to the ship, or are at risk for infection on the ship. Port health authorities, shipmasters, and doctors need to be well informed about the relevance of chickenpox on ships and the recommended control measures. Travellers should be advised to report to the ship doctor with any signs of infectious disease.

1998-12-01

Since 1994, we devised and have continued to develop a percutaneous trans esophageal gastro-tubing (PTEG) as an effective technique to drain gastrointestinal contents of critical patients suffering from gastric carcinoma. Here we report our satisfactory experience with a critical gastric cancer patient for whom we improved QOL by the application of the PTEG technique. The patient suffered from severe stenosis or obstruction of the digestive tract. This method was found to be effective enough to enable the patient to receive further medical care at home. The patient was a 36-year-old female who had far-advanced, inoperable gastric carcinoma. It was therefore decided to use the PTEG method. The PTEG method was performed using a rupture-free balloon (RFB) catheter to drain the gastrointestinal contents. A reservoir-port for IVH use was embedded to control the patient's nutrition. A morphine hydrochloride suppository was then given for the pain. PTEG was found to be effective, safe and simple; moreover, it is a less-invasive, intestine-maintaining method, which enabled the patient to continue receiving further medical treatment at home.

Radiation Port Cutaneous Metastases: Reports of Two Patients Whose Recurrent Visceral Cancers Presented as Skin Lesions at the Site of Previous Radiation and Literature Review

Hoyt, Brian Spencer; Cohen, Philip Randolph

2014-01-01

Radiation therapy is associated with a variety of complications, including the development of primary skin cancers in the radiated region. However, it is rare for patients with visceral cancers who are treated with radiation therapy to subsequently develop cutaneous metastasis within the radiation port. We describe two patients with internal malignancies who developed cutaneous metastases within their radiation ports following radiotherapy. In addition, we used PubMed to perform an extensive literature review and identify additional reports of cutaneous metastasis within a radiation port. We excluded patients who developed melanoma or primary skin cancers in the radiation port. We also excluded patients with non-solid organ malignancies. Herein, we summarize the characteristics of 23 additional patients who experienced radiation port cutaneous metastases and explore possible mechanisms for the occurrence of radiation port cutaneous metastases.

Potentially harmful dinoflagellates and diatoms are transported via ballast water to Galveston Bay, Texas (USA), home to three major ports: Houston, Texas City and Galveston. Ballast water from vessels transiting the North Atlantic Ocean was inoculated into treatments representing low and high salinity conditions similar to the Ports of Houston and Galveston respectively. Phytoplankton in ballast water growout experiments were deemed viable and showed growth in low and mid salinities with nutrient enrichment. Molecular methods identified several genera: Dinophysis, Gymnodinium, Gyrodinium, Heterocapsa, Peridinium, Scrippsiella, Chaetoceros and Nitzschia. These phytoplankton genera were previously identified in Galveston Bay except Scrippsiella. Phytoplankton, including those capable of forming harmful algal blooms leading to fish and shellfish kills, are transported to Galveston Bay via ballast water, and are viable when introduced to similar salinity conditions found in Galveston Bay ports.

Burskyte, Vilma; Belous, Olga; Stasiskiene, Zaneta

2011-06-01

In 2003, the Japan International Cooperation Agency carried out a development feasibility study of Klaipeda Seaport (Lithuania). The focus in this study was the evaluation of environmental impacts of the port expansion because it is located in an ecologically sensitive area. While the Japanese researchers focused on the environmental impact analysis, they did not provide unambiguous conclusions. The problems remained unresolved and required further, more detailed consideration and deeper analysis. Environmental sustainability in seaports is an issue of timely importance in many countries given the rapid increase in port-to-port traffic and harbor capacity. This paper explores the situation in Klaipeda Seaport (Lithuania) which is the northernmost ice-free port on the Eastern coast of the Baltic Sea and its challenges in terms of environmental aspects and current pollution situation. This port plays an important role in the economic development of the region and in creating a sustainable society, i.e., a society that continues to develop economically without increasing its impact on our living environment and where the possible reduction of its current impact can be huge due to the fact that the seaport is a place where transport and logistics intersect and constitute large-scale industrial estates. Increasingly, they also turn towards sustainability. Society faces the need for radical change because of increasing technological progress and increasing environmental impact. Environmental and public issues must be addressed by a systemic approach to find harmony among all the subsystems. Therefore, the authors of the article performed an assessment of the deep-water port of Klaipeda sustainable development opportunities tackling the following tasks: (1) Assessing Klaipeda port and the projected deep-water port of the current environment state; (2) Assessing the impact of the water quality of Klaipeda port, depending on the intensity of activity; (3) Assessing the projected impact of the deep-water port on the environment. The results of the performed research allowed: (a) to reveal strengths and weaknesses of Klaipeda port development and the potential conflicts of interest among different stakeholders, (b) to identify the set of problem solutions seeking sustainable Klaipeda port development; (c) to develop the set of sustainability indicators to monitor the efficiency of the development.

As being the heartlands of international trade, sea ports are the junction points of land and sea routes. The growth of global trade has led to the development of number and capacity as well as the service quality of ports. The policies and procedures applied during construction, operation and development of ports under development with environmental considerations scope has evolved in accordance with the needs of global trends. Although maritime transportation provides the most ecofriendly transportation method, the reduction of potential environmental threats and continuous improvement of ports and their vicinity is paramount from environmental concerns with regards to the international environmental standards. In the context of the study, national and international legal regulations governing the control of the environmental impacts of the activity groups causing pollution in Turkey based sea ports were viewed. In addition, the models applied during the measurement and documentation of environmental impacts were investigated. The most important aspects in terms of the effectiveness of the environmental management models are legal regulations. However, the standards applied at the ports without any legal obligation, such as EcoPorts applications, ISO 14001 standard, and the EMAS (Eco-Management and Audit Scheme) were sought in the scope of the study. The boundaries of the study were determined as the EU based Environmental Management Systems and the Green Port/Eco Port Project which is being administered by the Turkish Ministry of Transport, Maritime and Communication. “Marport”, which is Turkey’s first certified Green Port / Eco Port is designated as the experimental study site. In addition, the provisions in the ports of ESPO member countries are approached in order to compare the effectiveness and applicability of Green Port / Eco Port Project.

Parallelization of Rocket Engine System Software (Press)

Cezzar, Ruknet

1996-01-01

The main goal is to assess parallelization requirements for the Rocket Engine Numeric Simulator (RENS) project which, aside from gathering information on liquid-propelled rocket engines and setting forth requirements, involve a large FORTRAN based package at NASA Lewis Research Center and TDK software developed by SUBR/UWF. The ultimate aim is to develop, test, integrate, and suitably deploy a family of software packages on various aspects and facets of rocket engines using liquid-propellants. At present, all project efforts by the funding agency, NASA Lewis Research Center, and the HBCU participants are disseminated over the internet using world wide web home pages. Considering obviously expensive methods of actual field trails, the benefits of software simulators are potentially enormous. When realized, these benefits will be analogous to those provided by numerous CAD/CAM packages and flight-training simulators. According to the overall task assignments, Hampton University's role is to collect all available software, place them in a common format, assess and evaluate, define interfaces, and provide integration. Most importantly, the HU's mission is to see to it that the real-time performance is assured. This involves source code translations, porting, and distribution. The porting will be done in two phases: First, place all software on Cray XMP platform using FORTRAN. After testing and evaluation on the Cray X-MP, the code will be translated to C + + and ported to the parallel nCUBE platform. At present, we are evaluating another option of distributed processing over local area networks using Sun NFS, Ethernet, TCP/IP. Considering the heterogeneous nature of the present software (e.g., first started as an expert system using LISP machines) which now involve FORTRAN code, the effort is expected to be quite challenging.

2017-08-01

A two-port network model for a wireless power transfer system taking into account the distributed capacitances using PP network topology with top coupling is developed in this work. The operating and maximum power transfer efficiencies are determined analytically in terms of S-parameters. The system performance predicted by the model is verified with an experiment consisting of a high power home light load of 230 V, 100 W and is tested for two forced resonant frequencies namely, 600 kHz and 1.2 MHz. The experimental results are in close agreement with the proposed model.

Endoscopic surgery is currently a standard procedure in many countries. Furthermore, conventional four-port laparoscopic cholecystectomy is developing into a single-port procedure. However, in many developing countries, disposable medical products are expensive and adequate medical waste disposable facilities are absent. Advanced medical treatments such as laparoscopic or single-port surgeries are not readily available in many areas of developing countries, and there are often no other sterilization methods besides autoclaving. Moreover, existing reusable metallic ports are impractical and are thus not widely used. We developed a novel controllable, multidirectional single-port device that can be autoclaved, and with a wide working space, which was employed in five patients. In all patients, laparoscopic cholecystectomy was accomplished without complications. Our device facilitates single-port surgery in areas of the world with limited sterilization methods and offers a novel alternative to conventional tools for creating a smaller incision, decrease postoperative pain, and improve cosmesis. This novel device can also lower the cost of medical treatment and offers a promising tool for major surgeries requiring a wide working space.

The 1998 project ECOPORT, "Towards A Sustainable Transport Network", developed by the Valencia Port Authority (VPA), established the bases for implementing an Environmental Management System (EMS) in industrial harbours. The use of data and information shall always be required to develop an efficient EMS. The objective of the present research (INDAPORT) study is to propose a system of sustainable environmental management indicators to be used by any port authorities. All activities performed within a port area are analysed for any potential environmental impacts and risks. An environmental analysis of port activities has been carried out with the objective of designing the indicators system. Twenty-one corresponding activities have been identified for large industrial ports. Subsequently, the same methodology developed to date will be later applied to other Spanish and European ports. The study has been developed by using an original system and a methodology, which simultaneously use stage diagrams and systemic models (material and energy flow charts). Multi-criteria analysis techniques were used to evaluate potential impacts (identification of factors and evaluation of impacts).

NASA Astrophysics Data System (ADS)

Supian, L. S.; Ab-Rahman, Mohammad Syuhaimi; Harun, Mohd Hazwan; Gunab, Hadi; Sulaiman, Malik; Naim, Nani Fadzlina

2017-08-01

In visible optical communication over the multimode PMMA fibers, the overall cost of optical network can be reduced by deploying economical splitters for distributing the optical data signals from a point to multipoint in transmission network. The low-cost splitters shall have two main characteristics; good uniformity and high power efficiency. The most cost-effective and environmental friendly optical splitter having those characteristics have been developed. The device material is 100% purely based on the multimode step-index PMMA Polymer Optical Fiber (POF). The region which all fibers merged as single fiber is called as fused-taper POF. This ensures that all fibers are melted and fused properly. The results for uniformity and power efficiency of all splitters have been revealed by injecting red LED transmitter with 650 nm wavelength into input port while each end of output fibers measured by optical power meter. Final analysis shows our fused-taper splitter has low excess loss 0.53 dB and each of the output port has low insertion loss, which the average value is below 7 dB. In addition, the splitter has good uniformity that is 32:37:31% in which it is suitably used for demultiplexer fabrication.

ChromaStarPy: A Stellar Atmosphere and Spectrum Modeling and Visualization Lab in Python

Short, C. Ian; Bayer, Jason H. T.; Burns, Lindsey M.

2018-02-01

We announce ChromaStarPy, an integrated general stellar atmospheric modeling and spectrum synthesis code written entirely in python V. 3. ChromaStarPy is a direct port of the ChromaStarServer (CSServ) Java modeling code described in earlier papers in this series, and many of the associated JavaScript (JS) post-processing procedures have been ported and incorporated into CSPy so that students have access to ready-made data products. A python integrated development environment (IDE) allows a student in a more advanced course to experiment with the code and to graphically visualize intermediate and final results, ad hoc, as they are running it. CSPy allows students and researchers to compare modeled to observed spectra in the same IDE in which they are processing observational data, while having complete control over the stellar parameters affecting the synthetic spectra. We also take the opportunity to describe improvements that have been made to the related codes, ChromaStar (CS), CSServ, and ChromaStarDB (CSDB), that, where relevant, have also been incorporated into CSPy. The application may be found at the home page of the OpenStars project: http://www.ap.smu.ca/OpenStars/.

Secure computing is a necessity in the hostile environment that the internet has become. Protection from nefarious individuals and organizations requires a solution that is more a methodology than a one time fix. One aspect of this methodology is having the knowledge of which network ports a computer has open to the world, These network ports are essentially the doorways from the internet into the computer. An assessment method which uses the nmap software to scan ports has been developed to aid System Administrators (SAs) with analysis of open ports on their system(s). Additionally, baselines for several operating systems have been developed so that SAs can compare their open ports to a baseline for a given operating system. Further, the tool is deployed on a website where SAs and Users can request a port scan of their computer. The results are then emailed to the requestor. This tool aids Users, SAs, and security professionals by providing an overall picture of what services are running, what ports are open, potential trojan programs or backdoors, and what ports can be closed.

Environmental Factors' Consideration at Industrial Transportation Organization in the «Seaport - Dry port» System

NASA Astrophysics Data System (ADS)

Muravev, Dmitri; Rakhmangulov, Aleksandr

2016-11-01

Currently, container shipping development is directly associated with an increase of warehouse areas for containers' storage. One of the most successful types of container terminal is an intermodal terminal called a dry port. Main pollution sources during the organization of intermodal transport are considered. A system of dry port parameters, which are recommended for the evaluation of different scenarios for a seaport infrastructure development at the stage of its strategic planning, is proposed in this paper. The authors have developed a method for determining the optimal values of the main dry port parameters by simulation modeling in the programming software Any- Logic. Dependencies thatwere obtained as a result of modeling experiments prove the adequacy of main selected dry port parameters for the effective scenarios' evaluation of throughput and handling capacity at existing seaports at the stage of strategic planning and a rational dry port location, allowed ensuring the improvement of the ecological situation in a port city.

2007-11-01

Hybrid wavelength division multiplexing/optical code division multiple access (WDM/OCDMA) passive optical network (PON), where asynchronous OCDMA traffic transmits over WDM network, can be one potential candidate for gigabit-symmetric fiber-to-the-home (FTTH) services. In a cost-effective WDM/OCDMA network, a large scale multi-port encoder/decoder can be employed in the central office, and a low cost encoder/decoder will be used in optical network unit (ONU). The WDM/OCDMA system could be one promising solution to the symmetric high capacity access network with high spectral efficiency, cost effective, good flexibility and enhanced security. Asynchronous WDM/OCDMA systems have been experimentally demonstrated using superstructured fiber Bragg gratings (SSFBG) and muti-port OCDMA en/decoders. The total throughput has reached above Tera-bit/s with spectral efficiency of about 0.41. The key enabling techniques include ultra-long SSFBG, multi-port E/D with high power contrast ratio, optical thresholding, differential phase shift keying modulation with balanced detection, forward error correction, and etc. Using multi-level modulation formats to carry multi-bit information with single pulse, the total capacity and spectral efficiency could be further enhanced.

Assessment of Ports for Offshore Wind Development in the United States

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

Elkinton, Chris; Blatiak, Alicia; Ameen, Hafsa

As offshore wind energy develops in the United States, port facilities will become strategic hubs in the offshore wind farm supply chain because all plant and transport logistics must transit through these facilities. Therefore, these facilities must provide suitable infrastructure to meet the specific requirements of the offshore wind industry. As a result, it is crucial that federal and state policy-makers and port authorities take effective action to position ports in the offshore wind value chain to take best advantage of their economic potential. The U.S. Department of Energy tasked the independent consultancy GL Garrad Hassan (GL GH) with carryingmore » out a review of the current capability of U.S. ports to support offshore wind project development and an assessment of the challenges and opportunities related to upgrading this capability to support the growth of as many as 54 gigawatts of offshore wind installed in U.S. waters by 2030. The GL GH report and the open-access web-based Ports Assessment Tool resulting from this study will aid decision-makers in making informed decisions regarding the choice of ports for specific offshore projects, and the types of investments that would be required to make individual port facilities suitable to serve offshore wind manufacturing, installation and/or operations. The offshore wind industry in the United States is still in its infancy and this study finds that additional port facilities capable of supporting offshore wind projects are needed to meet the anticipated project build-out by 2030; however, no significant barriers exist to prevent the development of such facilities. Furthermore, significant port capabilities are in place today with purpose-build port infrastructure currently being built. While there are currently no offshore wind farms operating in the United States, much of the infrastructure critical to the success of such projects does exist, albeit in the service of other industries. This conclusion is based on GL GH’s review of U.S. ports infrastructure and its readiness to support the development of proposed offshore wind projects in U.S. waters. Specific examples of facility costs and benefits are provided for five coastal regions (North Atlantic, South Atlantic, Gulf of Mexico, Great Lakes, and Pacific) around the country. GL GH began this study by identifying the logistical requirements of offshore wind ports to service offshore wind. This review was based on lessons learned through industry practice in Northern Europe. A web-based port readiness assessment tool was developed to allow a capability gap analysis to be conducted on existing port facilities based on the identified requirements. Cost models were added to the assessment tool, which allowed GL GH to estimate the total upgrade cost to a port over the period 2014-2030 based on a set of regional project build-out scenarios. Port fee information was gathered from each port allowing an estimate of the potential revenue to the port under this same set of scenarios. The comparison of these revenue and improvement cost figures provides an initial indication of the level of offshore wind port readiness. To facilitate a more in-depth infrastructure analysis, six ports from different geographic regions, with varied levels of interest and preparedness towards offshore wind, were evaluated by modeling a range of installation strategies and port use types to identify gaps in capability and potential opportunities for economic development. Commonalities, trends, and specific examples from these case studies are presented and provide a summary of the current state of offshore wind port readiness in the U.S. and also illustrate the direction some ports have chosen to take to prepare for offshore wind projects. For example, the land area required for wind turbine and foundation manufacturing is substantial, particularly due to the large size of offshore wind components. Also, the necessary bearing capacities of the quayside and storage area are typically greater for offshore wind components than for more conventional cargo handling. As a result, most U.S. ports will likely require soil strength improvements before they can fully support offshore wind project construction. As U.S. ports and offshore wind developers look to work together on specific projects, they will encounter synergies and challenges. The challenges they face will include identifying sources of funding for the facility improvements required, and addressing ports’ typical desire to engage in long-term partnerships on the order of 10-20 years. Early projects will especially feel these challenges as they set the precedent for these partnerships in the United States. This study seeks to provide information about gaps, costs, and opportunities to aid these discussions.« less

A procedure to observe context-induced renewal of pavlovian-conditioned alcohol-seeking behavior in rats.

PubMed

Maddux, Jean-Marie; Lacroix, Franca; Chaudhri, Nadia

2014-09-19

Environmental contexts in which drugs of abuse are consumed can trigger craving, a subjective Pavlovian-conditioned response that can facilitate drug-seeking behavior and prompt relapse in abstinent drug users. We have developed a procedure to study the behavioral and neural processes that mediate the impact of context on alcohol-seeking behavior in rats. Following acclimation to the taste and pharmacological effects of 15% ethanol in the home cage, male Long-Evans rats receive Pavlovian discrimination training (PDT) in conditioning chambers. In each daily (Mon-Fri) PDT session, 16 trials each of two different 10 sec auditory conditioned stimuli occur. During one stimulus, the CS+, 0.2 ml of 15% ethanol is delivered into a fluid port for oral consumption. The second stimulus, the CS-, is not paired with ethanol. Across sessions, entries into the fluid port during the CS+ increase, whereas entries during the CS- stabilize at a lower level, indicating that a predictive association between the CS+ and ethanol is acquired. During PDT each chamber is equipped with a specific configuration of visual, olfactory and tactile contextual stimuli. Following PDT, extinction training is conducted in the same chamber that is now equipped with a different configuration of contextual stimuli. The CS+ and CS- are presented as before, but ethanol is withheld, which causes a gradual decline in port entries during the CS+. At test, rats are placed back into the PDT context and presented with the CS+ and CS- as before, but without ethanol. This manipulation triggers a robust and selective increase in the number of port entries made during the alcohol predictive CS+, with no change in responding during the CS-. This effect, referred to as context-induced renewal, illustrates the powerful capacity of contexts associated with alcohol consumption to stimulate alcohol-seeking behavior in response to Pavlovian alcohol cues.

Towards Efficient Scientific Data Management Using Cloud Storage

A software prototype allows users to backup and restore data to/from both public and private cloud storage such as Amazon's S3 and NASA's Nebula. Unlike other off-the-shelf tools, this software ensures user data security in the cloud (through encryption), and minimizes users operating costs by using space- and bandwidth-efficient compression and incremental backup. Parallel data processing utilities have also been developed by using massively scalable cloud computing in conjunction with cloud storage. One of the innovations in this software is using modified open source components to work with a private cloud like NASA Nebula. Another innovation is porting the complex backup to- cloud software to embedded Linux, running on the home networking devices, in order to benefit more users.

Predicting Human Mobility Patterns in Marine Ecosystems: Entropy and Home Range Calculations Based on High-Resolution Fishing Vessel Tracking Data

NASA Astrophysics Data System (ADS)

Murawski, S. A.

2016-02-01

A number of recent studies have developed metrics of human mobility patterns based on georeferenced cell phone records. The studies generally indicate a high degree of predictability in human location and relatively narrow home ranges for most people. In marine ecosystems there are a number of important uses for such calculations including marine spatial planning and predicting the impacts of marine management options such as establishing marine protected areas (MPAs). In this study we use individual fishing vessel satellite tracking (VMS) records ( 30 million records) obtained from commercial reef fish fishing vessels in the Gulf of Mexico during 2006-2014. This period witnessed the establishment of a variety of new regulations including individual fishing quotas (IFQs) for snapper, grouper, and tilefish, establishment of spatial-area closures, and the temporary closure of as much as 85,000 nautical miles of productive fishing grounds associated with the Deepwater Horizon oil spill accident. Vessel positions were obtained, with a location frequency of one hour. From these VMS data we calculated three measures of entropy (degree of repeatability in spatial use), as well as calculated the axis of gyration (home range) for each vessel in the data set. These calculations were related to a variety of descriptor variables including vessel size, distance from home port to predominant fishing grounds, revenue generated on fishing trips, and fishing regulations. The applicability of these calculations to marine resource management applications is discussed.

2017-06-15

In general, Synthetic Indexes of sustainability have been applied to specific countries and regions. With some variations, the ones considered simple, such as the case of the Ecological Footprint (EF), have been applied to port areas. The same has not happened with those of a multidimensional nature (Global Synthetics) that still have a minimal and partial presence in the analysis of port sustainability. Understanding that this type of index represents an interesting and novel avenue of research applied to port systems, this contribution analyses and ranks a sample of 16 Spanish Port Authorities that group 23 ports of general interest using a Global Synthetic Index of Sustainability (developed using the four dimensions of sustainable development: economic, institutional, environmental and social).

Queuing theory models used for port equipment sizing

NASA Astrophysics Data System (ADS)

Dragu, V.; Dinu, O.; Ruscă, A.; Burciu, Ş.; Roman, E. A.

2017-08-01

The significant growth of volumes and distances on road transportation led to the necessity of finding solutions to increase water transportation market share together with the handling and transfer technologies within its terminals. It is widely known that the biggest times are consumed within the transport terminals (loading/unloading/transfer) and so the necessity of constantly developing handling techniques and technologies in concordance with the goods flows size so that the total waiting time of ships within ports is reduced. Port development should be achieved by harmonizing the contradictory interests of port administration and users. Port administrators aim profit increase opposite to users that want savings by increasing consumers’ surplus. The difficulty consists in the fact that the transport demand - supply equilibrium must be realised at costs and goods quantities transiting the port in order to satisfy the interests of both parties involved. This paper presents a port equipment sizing model by using queueing theory so that the sum of costs for ships waiting operations and equipment usage would be minimum. Ship operation within the port is assimilated to a mass service waiting system in which parameters are later used to determine the main costs for ships and port equipment.

Research into the methodological development of alternative systems of sustainability measures is recent. In understanding sustainable development in a multi-dimensional sense, one of the most significant advances was the construction of Synthetic Indexes, applicable to different spatial spheres or to organisations, businesses, institutions, etc. The Spanish port system of general interest comprises 46 ports integrated in 28 Port Authorities, which in 2014 moved 482,000,000t of goods and more than 28 million passengers. This gives an idea of its importance for the Spanish economy. Using a derivation of the procedure used to calculate the Port Sustainability Synthetic Index, in this research the analysis of the relationship that exists between the findings obtained for the economic and environmental dimensions is used. This enables the existence of links between ports and economic and environmental indicators for a sample of 16 Port Authorities of Spain to be verified. Copyright © 2016 Elsevier Ltd.

Nguyen, T. D. H.; Cools, M.

2018-04-01

This paper presents the current operating status in Da Nang Port, Vietnam in the period 2012-2016. The port operation had positive changes that were reflected by a significant increase in total throughputs, especially containerized cargo volumes. Classical decomposition techniques are used to find trend-cycle and seasonal components of monthly throughput flows. Appropriate predictive models of different kinds of throughputs are proposed. Finally, a development strategy towards containerization and investment policies in facilities, equipment, and infrastructure are suggested based on the predictive results.

Remote medical monitoring network for long-term monitoring of physiological variables would be helpful for recovery of patients as people are monitored at more comfortable conditions. Furthermore, long-term monitoring would be beneficial to investigate slowly developing deterioration in wellness status of a subject and provide medical treatment as soon as possible. The home monitor runs on an embedded microcomputer Rabbit3000 and interfaces with different medical monitoring module through serial ports. The network based on asymmetric digital subscriber line (ADSL) or local area network (LAN) is established and a client - server model, each embedded home medical monitor is client and the monitoring center is the server, is applied to the system design. The client is able to provide its information to the server when client's request of connection to the server is permitted. The monitoring center focuses on the management of the communications, the acquisition of medical data, and the visualization and analysis of the data, etc. Diagnosing model of sleep apnea syndrome is built basing on ECG, heart rate, respiration wave, blood pressure, oxygen saturation, air temperature of mouth cavity or nasal cavity, so sleep status can be analyzed by physiological data acquired as people in sleep. Remote medical monitoring network based on embedded micro Internetworking technology have advantages of lower price, convenience and feasibility, which have been tested by the prototype.

Single port VATS: recent developments in Asia.

PubMed

Yu, Peter S Y; Capili, Freddie; Ng, Calvin S H

2016-03-01

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.

Determination of burning area and port volume in complex burning regions of a solid rocket motor

NASA Technical Reports Server (NTRS)

Kingsbury, J. A.

1977-01-01

An analysis of the geometry of the burning in both star-cylindrical port interface regions and regions of partially inhibited slots is presented. Some characteristics parameters are defined and illustrated. Methods are proposed for calculating burning areas which functionally depend only on the total distance burned. According to this method, several points are defined where abrupt changes in geometry occur, and these are tracked throughout the burn. Equations are developed for computing port perimeter and port area at pre-established longitudinal positions. Some common formulas and some newly developed formulas are then used to compute burning surface area and port volume. Some specific results are presented for the solid rocket motor committed to the space shuttle project.

Water quality assessment of Australian ports using water quality evaluation indices

Jahan, Sayka

2017-01-01

Australian ports serve diverse and extensive activities, such as shipping, tourism and fisheries, which may all impact the quality of port water. In this work water quality monitoring at different ports using a range of water quality evaluation indices was applied to assess the port water quality. Seawater samples at 30 stations in the year 2016–2017 from six ports in NSW, Australia, namely Port Jackson, Botany, Kembla, Newcastle, Yamba and Eden, were investigated to determine the physicochemical and biological variables that affect the port water quality. The large datasets obtained were designed to determine the Water Quality Index, Heavy metal Evaluation Index, Contamination Index and newly developed Environmental Water Quality Index. The study revealed medium water quality index and high and medium heavy metal evaluation index at three of the study ports and high contamination index in almost all study ports. Low level dissolved oxygen and higher level of total dissolved solids, turbidity, fecal coliforms, copper, iron, lead, zinc, manganese, cadmium and cobalt are mainly responsible for the poor water qualities of the port areas. Good water quality at the background samples indicated that various port activities are the likely cause for poor water quality inside the port area. PMID:29244876

Distribution of polychlorinated biphenyl residues in sediments and blue mussels (Mytilus galloprovincialis) from Port Elizabeth Harbour, South Africa.

PubMed

Kampire, E; Rubidge, G; Adams, J B

2015-02-15

Sediment and Mytilus galloprovincialis samples collected from the Port Elizabeth Harbour were analysed for six indicator PCB congeners to assess their contamination status. The concentrations of total PCBs in sediments and M. galloprovincialis ranged from 0.56 to 2.35 ng/g dry weight and 14.48 to 21.37 ng/g wet weight, respectively. Congeners 138 and 153 were dominant and accounted for an average of 29% and 24% of total PCBs in M. galloprovincialis; 32% and 30% in sediments, respectively. Sediments are home to a wide variety of aquatic life. None of the sediments analysed exceeded the PCB limits recommended the Canadian interim sediment quality guideline and the South African recommended sediment guidelines (21.6 ng/g). Both humans and aquatic life are sensitive to the toxic effects of PCBs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Care of dogs and attitudes of dog owners in Port-au-Prince, the Republic of Haiti.

Fielding, William J; Gall, Melanie; Green, Dick; Eller, Warren S

2012-01-01

This article reports the first known study on dogs in Port-au-Prince. Interviews with 1,290 residents provided information on 1,804 dogs. More than 57.7% of homes kept dogs. Not all the dogs received vaccinations for rabies (41.6%), even though 28.2% of households had had a household member bitten by a dog. Although the "owned" dog population had decreased as a result of the earthquake in January 2010, the number of roaming dogs appeared to have been uninfluenced by the disaster. Given that 64.8% of dogs probably had access to the street and only 6.0% of the females were spayed, to humanely contain the dog population will require both confinement and neutering. Although roaming dogs were considered a nuisance by 63.3% of respondents, 42.6% of households fed dogs they did not own.

Usefulness of a Flexible Port for Natural Orifice Transluminal Endoscopic Surgery by the Transrectal and Transvaginal Routes

2010-01-01

We developed a flexible port for NOTES which allows the use of conventional forceps for laparoscope-assisted surgery without change. The port is not affected by the location of the through hole in the gastrointestinal tract or vagina which elicits a problem in conventional NOTES, and its length can be adjusted during surgery by cutting the port itself. The port is made of polymer resin with a low friction coefficient. Furthermore, the port walls have a square wave structure which contributes to (1) the prevention of devices, for example, endoscope, from getting stuck at the time of insertion and retrieval, (2) the prevention of port slippage in the surgical opening for port insertion, (3) the prevention of unexpected port removal, (4) the prevention of port bore deformation, and (5) the improvement of port flexibility in the longitudinal direction. We validated the insertion and retrieval capacities of commercially available forceps for laparoscope-assisted surgery and power devices. Furthermore, we used the flexible port to conduct cholecystectomy and partial gastrectomy. We could confirm that the selection of the flexible port diameter according to the device type allowed the smooth insertion and retrieval of the device and that the port produced no air leakage. We affirmed that it is possible to conduct surgery by the cross or parallel method similarly to single port surgery. We considered that the flexible port has a potential of becoming a revolutionary port in NOTES. PMID:20508827

2018-01-01

The Community model for near-PORT applications (C-PORT) is a screening tool with an intended purpose of calculating differences in annual averaged concentration patterns and relative contributions of various source categories over the spatial domain within about 10 km of the port. C-PORT can inform decision-makers and concerned citizens about local air quality due to mobile source emissions related to commercial port activities. It allows users to visualize and evaluate different planning scenarios, helping them identify the best alternatives for making long-term decisions that protect community health and sustainability. The web-based, easy-to-use interface currently includes data from 21 seaports primarily in the Southeastern U.S., and has a map-based interface based on Google Maps. The tool was developed to visualize and assess changes in air quality due to changes in emissions and/or meteorology in order to analyze development scenarios, and is not intended to support or replace any regulatory models or programs.

2016-01-01

To analyze the outcomes of single-port laparoscopic cholecystectomy. Early and long-term postoperative period has been analyzed in 240 patients who underwent laparoscopic cholecystectomy (LCE) including 120 cases of single-port technique and 120 cases of four-port technique. Both groups were compared in surgical time, pain syndrome severity (visual analog scale), need for analgesics, postoperative complications, hospital-stay, daily activity recovery and return to physical work, patients' satisfaction of surgical results and their aesthetic effect. It was revealed that single-port LCE is associated with lower severity of postoperative pain, quick recovery of daily activity and return to physical work, high satisfaction of surgical results and their aesthetic effect compared with four-port LCE. Disadvantages of single-port LCE include longer duration of surgery, high incidence of postoperative umbilical hernia. However hernia was predominantly observed during the period of surgical technique development. Further studies to standardize, evaluate the safety and benefits of single-port LCE are necessary.

A novel BCI-controlled pneumatic glove system for home-based neurorehabilitation.

PubMed

Coffey, Aodhán L; Leamy, Darren J; Ward, Tomás E

2014-01-01

Commercially available devices for Brain-Computer Interface (BCI)-controlled robotic stroke rehabilitation are prohibitively expensive for many researchers who are interested in the topic and physicians who would utilize such a device. Additionally, they are cumbersome and require a technician to operate, increasing the inaccessibility of such devices for home-based robotic stroke rehabilitation therapy. Presented here is the design, implementation and test of an inexpensive, portable and adaptable BCI-controlled hand therapy device. The system utilizes a soft, flexible, pneumatic glove which can be used to deflect the subject's wrist and fingers. Operation is provided by a custom-designed pneumatic circuit. Air flow is controlled by an embedded system, which receives serial port instruction from a PC running real-time BCI software. System tests demonstrate that glove control can be successfully driven by a real-time BCI. A system such as the one described here may be used to explore closed loop neurofeedback rehabilitation in stroke relatively inexpensively and potentially in home environments.

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&D topics are outlined.

Ultrasmall multi-channel resonant-tunneling filter using mode gap of width-tuned photonic-crystal waveguide.

2005-05-30

We have devised an ultra-small multi-channel drop filter based on a two-port resonant tunneling system in a two-dimensional photonic crystal with a triangular air-hole lattice. This filter does not require careful consideration of the interference process to achieve a high dropping efficiency. First we develop three-port systems based on a two-port resonant tunneling filter. Next we devise a multi-port channel drop filter by cascading these three-port systems. In this paper, we demonstrate a ten-channel drop filter with an 18 mum device size by 2D-FDTD calculation, and a three-port resonant tunneling filter with 65+/- 20 % dropping efficiency by experiment.

2015-01-01

The paper outlines and specifies 'responsible port innovation', introducing the development of a methodological and procedural step-by-step plan for the implementation and evaluation of (responsible) innovations. Subsequently, it uses this as a guideline for the analysis and evaluation of two case-studies. The construction of the Rotterdam Maasvlakte 2 Port meets most of the formulated requirements, though making values more explicit and treating it as a process right from the start could have benefitted the project. The Dalian Dayao Port could improve its decision-making procedures in several respects, including the introduction of new methods to handle value tensions. Both projects show that public support is crucial in responsible port innovation and that it should be not only a multi-faceted but also a multi-level strategy.

This paper analyses the 2016 environmental benchmark performance of the port sector, based on a wide representation of EcoPorts members. This is the fifth time that this study has been conducted as an initiative of the European Sea Ports Organisation (ESPO). The data and results are derived from the Self-Diagnosis Method (SDM), a concise checklist against which port managers can self-assess the environmental management of their port in relation to the performance of the EcoPorts membership. The SDM tool was developed in the framework of the ECOPORTS project (2002-2005) and it is managed by ESPO. A total number of 91 ports from 20 different European Maritime States contributed to this evaluation. The main results are that air quality remains as the top environmental priority of the respondent ports, followed by energy consumption and noise. In terms of environmental management, the study confirms that key components are commonly implemented in the majority of European ports. 94% of contributing ports have a designated environmental manager, 92% own an environmental policy and 82% implement an environmental monitoring program. Waste is identified as the most monitored issue in ports (80%), followed by energy consumption (73%) and water quality (70%). Copyright © 2017 Elsevier Ltd. All rights reserved.

There has been little enthusiasm for performing robotic colectomy for colon cancer in recent years due to multiple factors, one being that the previous robotic systems such as the da Vinci Si ® (dVSi) were poorly designed for multi-quadrant surgery. The new da Vinci Xi ® (dVXi) system enables colectomy with central mesocolic excision to be performed easily in a single docking procedure. We developed a universal port placement strategy to allow right and left hemicolectomies to be performed via a suprapubic approach and a Pfannensteil extraction site. This proof of concept paper describes the development and subsequent clinical application of this setup. After extensive training on the dVXi system concepts in collaboration with clinical development engineers, we developed a port placement strategy which was tested and adapted after performing experimental surgery in three cadaveric models. Subsequently our port placement was used for two clinical cases of suprapubic right and left hemicolectomy. With some modifications of port placements after the initial cadaveric colectomies, we have developed a potentially universal suprapubic port placement strategy for robotic colectomy with complete mesocolic excision and central vascular ligation using the dVXi robotic system. This port placement strategy was applied successfully in our first two clinical cases. Based on our cadaveric laboratory as well as our initial clinical application, the suprapubic port placement strategy for the dVXi system with its improved features over the dVSi can feasibly perform right and left hemicolectomy with complete mesocolic excision and central vascular ligation. Further studies will be required to establish efficacy as well as safety profile of these procedures.

The competition among maritime ports is increasing continuously; the main purpose of Safaga port is to become the best option for companies to carry out their trading activities, particularly importing and exporting The main objective of this research is to evaluate and analyze factors that may significantly affect the levels of Safaga port efficiency in Egypt (particularly the infrastructural capacity). The assessment of such efficiency is a task that must play an important role in the management of Safaga port in order to improve the possibility of development and success in commercial activities. Drawing on Data Envelopment Analysis(DEA)models, this paper develops a manner of assessing the comparative efficiency of Safaga port in Egypt during the study period 2004-2013. Previous research for port efficiencies measurement usually using radial DEA models (DEA-CCR), (DEA-BCC), but not using non radial DEA model. The research applying radial - output oriented (DEA-CCR), (DEA-BCC) and non-radial (DEA-SBM) model with ten inputs and four outputs. The results were obtained from the analysis input and output variables based on DEA-CCR, DEA-BCC and SBM models, by software Max DEA Pro 6.3. DP World Sokhna port higher efficiency for all outputs were compared to Safaga port. DP World Sokhna position is below the southern entrance to the Suez Canal, on the Red Sea, Egypt, makes it strategically located to handle cargo transiting through one of the world's busiest commercial waterways.

To measure the electron temperature (T(e)) and electron density (n(e)) profiles in the Korean Superconducting Tokamak Advanced Research (KSTAR) device for the KSTAR third campaign (September 2010), we designed and installed a Thomson scattering system. The KSTAR Thomson scattering system is designed as a tangential Thomson scattering system and utilizes the N-, L-, and B-ports. The N-port is designed for the collection optics with a cassette system, the L-port is the laser input port, and the B-port is the location of the beam dump. In this paper, we will describe the final design of the KSTAR Thomson scattering system.

Real success in the residential broadband market is contingent on a platform that most efficiently shares broadband port costs while at the same time affords us an elegant, and cost efficient, upgrade from today's analog to tomorrow's digital world. Spectrum transport, whether it be over new or existing fiber/coax systems or FTTC, is that platform. It is compatible with today's home entertainment market, can be evolved to future digital transport, and effectively shares the cost of interfacing with a broadband network.

GR718 is a radiation tolerant 18 port standalone SpaceWire router component that has been developed by Cobham Gaisler together with IMEC (BE), in an activity initiated by the European Space Agency under ESTEC contract 4000105402/12/NL/Cbi. Out of the 18 SpaceWire ports, 16 use on-chip LVDS transceivers, and two use LVTTL signaling. Included also is the mandatory configuration port, as well as an internal port for system level testing. All ports are capable of operating in 200 Mbit/s. UART and JTAG interfaces, that gives access to the on-chip AMBA AHB bus, are provided for configuration and debugging. SPI and GPIO interfaces are accessible through the configuration port, which allows SPI devices to be accessed and general purpose signaling to be performed through RMAP commands. In addition to the mandatory features in the current ECSS SpaceWire standard, GR718 supports group adaptive routing for path addresses, and packet distribution. It also includes support for the incoming SpaceWire standard revision 1 (ECSS-E-ST-50-12C Rev.1), the SpaceWire-D protocol, and the SpaceWire Plug-and-Play protocol currently being developed for ECSS. The technology used is UMC 180 nm, using the DARE library from IMEC, and the package is a 256 pin CQFP. A development board for evaluation and software development has been manufactured as well.

Ultrasound-assisted emulsification microextraction combined with injection-port derivatization for the determination of some chlorophenoxyacetic acids in water samples.

Yamini, Yadollah; Saleh, Abolfazl

2013-07-01

An efficient method based on ultrasound-assisted emulsification microextraction followed by injection-port derivatization GC analysis was developed to determine 2,4-dichlorophenoxyacetic acid (2,4-D) and 4-chloro-2-methylphenoxyacetic acid (MCPA) in natural water samples. In this procedure, 12.5 μL of 1-undecanol was injected slowly into a 12 mL home-designed centrifuge glass vial containing an aqueous sample of the analytes located inside an ultrasonic water bath. The resulting emulsion was centrifuged, and 1 μL of the separated organic solvent together with 1 μL of the derivatization reagent were injected into a GC equipped with a flame ionization detector. Several factors that influence the derivatization and extraction were optimized. Under the optimal conditions, the LODs were 0.33 and 1.7 μg/L for MCPA and 2,4-D, respectively. Preconcentration factors of 670 and 836 were obtained for MCPA and 2,4-D, respectively. The precision of the proposed method was evaluated in terms of repeatability, which was <5.7% (n = 5). The applicability of the proposed method was evaluated by extraction and determination of chlorophenoxyacetic acids from some natural waters, which indicated that the matrices of natural waters have no significant effect on the extraction and derivatization efficiency of this method. © 2013 WILEY-VCH Verlag GmbH & Co.

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.

In an effort to better understand the operational requirements of port drayage vehicles and their potential for adoption of advanced technologies, National Renewable Energy Laboratory (NREL) researchers collected over 36,000 miles of in-use duty cycle data from 30 Class 8 drayage trucks operating at the Port of Long Beach and Port of Los Angeles in Southern California. These data include 1-Hz global positioning system location and SAE J1939 high-speed controller area network information. Researchers processed the data through NREL's Drive-Cycle Rapid Investigation, Visualization, and Evaluation tool to examine vehicle kinematic and dynamic patterns across the spectrum of operations. Using themore » k-medoids clustering method, a repeatable and quantitative process for multi-mode drive cycle segmentation, the analysis led to the creation of multiple drive cycles representing four distinct modes of operation that can be used independently or in combination. These drive cycles are statistically representative of real-world operation of port drayage vehicles. When combined with modeling and simulation tools, these representative test cycles allow advanced vehicle or systems developers to efficiently and accurately evaluate vehicle technology performance requirements to reduce cost and development time while ultimately leading to the commercialization of advanced technologies that meet the performance requirements of the port drayage vocation. The drive cycles, which are suitable for chassis dynamometer testing, were compared to several existing test cycles.

The NEID spectrograph is an optical (380-930 nm), fiber-fed, precision Doppler spectrograph currently in development for the 3.5 m WIYN Telescope at Kitt Peak National Observatory. Designed to achieve a radial velocity precision of <30 cm/s, NEID will be sensitive enough to detect terrestrial-mass exoplanets around low-mass stars. Light from the target stars is focused by the telescope to a bent-Cassegrain port at the edge of the primary mirror mechanical support. The specialized NEID “Port Adapter” system is mounted at this bent-Cassegrain port and is responsible for delivering the incident light from the telescope to the NEID fibers. In order to provide stable, high-quality images to the science instrument, the Port Adapter houses several subcomponents designed to acquire the target stars, correct for atmospheric dispersion, stabilize the light onto the science fibers, and calibrate the spectrograph by injecting known wavelength sources such as a laser frequency comb. Here we describe the overall design of the Port Adapter and outline the development of calibration tools and an on-sky test plan to verify the performance of the atmospheric dispersion corrector (ADC). We also discuss the development of an error budget and test requirements to ensure high-precision centroiding onto the NEID science fibers using a system of coherent fiber bundles.

Intracorporeal hybrid single port vs conventional laparoscopic appendectomy in children.

Karam, Paul Anthony; Hiuser, Amy; Magnuson, David; Seifarth, Federico Gian Filippo

2016-12-20

Transumbilical laparoscopic assisted appendectomy combines laparoscopic single port dissection with open appendectomy after exteriorization of the appendix through the port site. Compared to the conventional three-port approach, this technique provides an alternative with excellent cosmetic outcome. We developed a safe and effective technique to perform an intracorporeal single port appendectomy, using the same laparoscope employed in the extracorporeal procedure. Retrospective review of 71 consecutively performed intracorporeal single port appendectomies and 30 conventional three-port appendectomies in children 6 to 17 years of age. A straight 10-mm Storz telescope with inbuilt 6 mm working channel is used to dissect the appendix, combined with one port-less 2.3 mm percutaneous grasper. Polymer WECK® hem-o-lock® clips are applied to seal the base of the appendix and the appendiceal vessels. No intraoperative complications were reported with the hybrid intracorporeal single port appendectomy or three-port appendectomy. There were two post-operative complications in the group treated with the single port hybrid technique: one intra-abdominal abscess and one surgical site infection. Groups did not differ in age, weight, and types of appendicitis. Operative times were shorter for the hybrid technique (70 vs 79 minutes) but did not differ significantly (P=0.19). This modified technique to a previously described single port extracorporeal appendectomy is easy to master and implement. It provides exposure similar to a three-port laparoscopic appendectomy, while maintaining virtually scarless results and potentially reduces the risk for surgical site infections compared to the extracorporeal technique.

Bonamano, Simone; Madonia, Alice; Piazzolla, Daniele; Paladini de Mendoza, Francesco; Piermattei, Viviana; Scanu, Sergio; Melchiorri, Cristiano; Marcelli, Marco

2017-04-01

Within the Water Framework Directive (WFD), harbours must reach or maintain the good ecological potential, being classified as heavily modified water bodies. To fulfill this task and to comply the Marine Spatial Planning (MSP) principles, port managers have to monitor the water quality that can be compromised by the numerous activities including the realization of new infrastructures. The port of Civitavecchia, located on the central west coast of Italy, is undergoing to major structural changes to become one of the first ports of the Mediterranean in terms of passenger traffic and goods, thus requiring the development of management tools for the predictive assessment of harbour water quality. This study focused on the evaluation of water degradation within Civitavecchia port trough the calculation of Flushing time (FT) and the development of the new Flushing Efficiency Index (FEI). FT was calculated through the use of a numerical model under different scenarios selected combining different weather conditions with the new port configurations. FT values was then used to estimate the FEI for the evaluation of the improvement (positive values) or the deterioration (negative values) of water quality in the different zones of the port. The increase in the harbour basin size due to the embankment extension results in high values of FT, particularly in the inner part of the port, in accordance with the highest values of the Enrichment Factor (EF) of the trace metals found in the sediment. The correlation between FT and EF confirms that renewal time can be used as a proxy to evaluate the water quality conditions in the harbour basin, as also stated by the WFD guidelines. Also the results of FEI calculation indicate the potential occurrence of water degradation due to the embankment extension. Otherwise, the realization of a second entrance in the southern part of Civitavecchia port produces FEI positive values, highlighting a drastic improvement in harbour water renewal. Consistent with Blue Growth and Bluemed initiatives, the new tools developed in this study support the sustainable management of port activities, thereby also contributing to the development of new "blue jobs."

Analysis of laparoscopic port site complications: A descriptive study

PubMed Central

Karthik, Somu; Augustine, Alfred Joseph; Shibumon, Mundunadackal Madhavan; Pai, Manohar Varadaraya

2013-01-01

CONTEXT: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. AIMS: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. SETTINGS AND DESIGN: Prospective descriptive study. MATERIALS AND METHODS: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. STATISTICAL ANALYSIS USED: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. RESULTS: Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). CONCLUSIONS: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit. PMID:23741110

Anterior segment sparing to reduce charged particle radiotherapy complications in uveal melanoma

PURPOSE: The purpose of this investigation is to delineate the risk factors in the development of neovascular glaucoma (NVG) after helium-ion irradiation of uveal melanoma patients and to propose treatment technique that may reduce this risk. METHODS AND MATERIALS: 347 uveal melanoma patients were treated with helium-ions using a single-port treatment technique. Using univariate and multivariate statistics, the NVG complication rate was analyzed according to the percent of anterior chamber in the radiation field, tumor size, tumor location, sex, age, dose, and other risk factors. Several University of California San Francisco-Lawrence Berkeley National Laboratory (LBNL) patients in each size category (medium, large, and extralarge) were retrospectively replanned using two ports instead of a single port. By using appropriate polar and azimuthal gaze angles or by treating patients with two ports, the maximum dose to the anterior segment of the eye can often be reduced. Although a larger volume of anterior chamber may receive a lower dose by using two ports than a single port treatment. We hypothesize that this could reduce the level of complications that result from the irradiation of the anterior chamber of the eye. Dose-volume histograms were calculated for the lens, and compared for the single and two-port techniques. RESULTS: NVG developed in 121 (35%) patients. The risk of NVG peaked between 1 and 2.5 years posttreatment. By univariate and multivariate analysis, the percent of lens in the field was strongly correlated with the development of NVG. Other contributing factors were tumor height, history of diabetes, and vitreous hemorrhage. Dose-volume histogram analysis of single-port vs. two-port techniques demonstrate that for some patients in the medium and large category tumor groups, a significant decrease in dose to the structures in the anterior segment of the eye could have been achieved with the use of two ports. CONCLUSION: The development of NVG after helium-ion irradiation is correlated to the amount of lens, anterior chamber in the treatment field, tumor height, proximity to the fovea, history of diabetes, and the development of vitreous hemorrhage. Although the influence of the higher LET deposition of helium-ions is unclear, this study suggests that by reducing the dose to the anterior segment of the eye may reduce the NVG complications. Based on this retrospective analysis of LBNL patients, we have implemented techniques to reduce the amount of the anterior segment receiving a high dose in our new series of patients treated with protons using the cyclotron at the UC Davis Crocker Nuclear Laboratory (CNL).

Engagement in sexual activity among Haitian youth is increasing. The present cross-sectional study examined the independent correlates of sexual risk behaviors among 200 (108 male/92 female) 13-18 year-old adolescents in Port-au-Prince, Haiti using face-to-face interviews. The majority (60.0 %) had engaged in sexual intercourse. Multivariate modeling found males to be 3.52 times more likely to have had sex, 5.42 times more likely to report sexual debut before age 14, 9.75 times more likely to have >1 sexual partner, and 3.33 times more likely to not have used a condom during last sex. Adolescents living with parents, grandparents, aunts or uncles were less likely to report having unprotected sex compared with those without adult family members in the home (AOR range 0.26-0.51). The high prevalence of risky sex among males and the protective influence of stable family cohesiveness have important implications for HIV prevention efforts.

To evaluate the incidence and possible predictors associated with port-site metastases following robotic surgery. Prospective study. University Hospital. Women with gynecological cancer. The occurrence of port-site metastases in the first 475 women undergoing robotic surgery for gynecological cancer was reviewed. Rate of port-site metastases. A port-site metastasis was detected in nine of 475 women (1.9%). Eight women had either an unexpected locally advanced disease or lymph-node metastases at the time of surgery. All nine women received postoperative adjuvant therapy. Women with ≥ stage III endometrial cancer and women with node positive cervical cancer had a significantly higher risk of developing a port-site metastasis, as did women with high-risk histology endometrial cancer. Port-site metastases were four times more likely to occur in a specimen-retrieval port. One (0.2%) isolated port-site metastasis was detected. The median time to occurrence of a port-site metastasis was 6 months (range 2-19 months). Six of the nine women (67%) have died and their median time of survival from recurrence was 4 months (range 2-16 months). In women with gynecological cancer, the incidence of port-site metastases following robotic surgery was 1.9%. High-risk histology and/or advanced stage of disease at surgery seem to be contributing factors. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

High costs and a paucity of available operating time have led us to seek alternatives to operatively placed vascular access systems. This prospective study is the initial report of a peripheral port system (P.A.S. PORT System, Pharmacia Deltec, Inc.) placed at the bedside. Seventy-nine patients (52 male, 27 female), ages 3-92 years, had ports implanted by surgical residents with attending supervision. Sixty-eight (86%) received the P.A.S. PORT for long-term antibiotics, antifungal, or antiviral therapy; four (5%) for TPN infusion; three (4%) for blood products; two (3%) for chemotherapy; and two (3%) for iv narcotics. Ports were placed in 10 (13%) HIV(+) patients, three (4%) who were fully anticoagulated, and one who was a hemophiliac with a platelet count of zero. Eight patients (10%) developed superficial phlebitis, all of which resolved with nonsteroidal anti-inflammatory agents within 48 hr without port removal. Seven patients (9%) had their port removed due to infection. The average hospital charge to place the P.A.S. PORT System was $1488.00 vs $2811.00 for a tunneled external chest catheter and $3729.00 for the placement of a chest port. Bedside insertion of vascular access devices can be safely performed with acceptable infection rates allowing more efficient use of hospital operating rooms and with substantial cost savings.

Minimally invasive transportal resection of deep intracranial lesions has become a widely accepted surgical technique. Many disposable, mountable port systems are available in the market for this purpose, like the ViewSite Brain Access System. The objective of this study was to find a cost-effective substitute for these systems. Deep-seated brain lesions were treated with a port system made from disposable syringes. The syringe port could be inserted through minicraniotomies placed and planned with navigation. All deep-seated lesions like ventricular tumours, colloid cysts, deep-seated gliomas, and basal ganglia hemorrhages were treated with this syringe port system and evaluated for safety, operative site hematomas, and blood loss. 62 patients were operated on during the study period from January 2015 to July 2017, using this innovative syringe port system for deep-seated lesions of the brain. No operative site hematoma or contusions were seen along the port entry site and tract. Syringe port is a cost-effective and safe alternative to the costly disposable brain port systems, especially for neurosurgical setups in developing countries for minimally invasive transportal resection of deep brain lesions.

2018-06-01

An original method able to fully characterize high-Q resonators in an add-drop configuration has been implemented. The method is based on the study of two cavity ringdown (CRD) signals, which are produced at the transmission and drop ports by wavelength sweeping a resonance in a time interval comparable with the photon cavity lifetime. All the resonator parameters can be assessed with a single set of simultaneous measurements. We first developed a model describing the two CRD output signals and a fitting program able to deduce the key parameters from the measured profiles. We successfully validated the model with an experiment based on a fiber ring resonator of known characteristics. Finally, we characterized a high-Q, home-made, MgF2 whispering gallery mode disk resonator in the add-drop configuration, assessing its intrinsic and coupling parameters.

Assessing the port to port risk of vessel movements vectoring non-indigenous marine species within and across domestic Australian borders.

PubMed

Campbell, Marnie L; Hewitt, Chad L

2011-07-01

Biofouling of vessels is implicated as a high risk transfer mechanism of non-indigenous marine species (NIMS). Biofouling on international vessels is managed through stringent border control policies, however, domestic biofouling transfers are managed under different policies and legislative arrangements as they cross internal borders. As comprehensive guidelines are developed and increased compliance of international vessels with 'clean hull' expectations increase, vessel movements from port to port will become the focus of biosecurity management. A semi-quantitative port to port biofouling risk assessment is presented that evaluates the presence of known NIMS in the source port and determines the likelihood of transfer based on the NIMS association with biofouling and environmental match between source and receiving ports. This risk assessment method was used to assess the risk profile of a single dredge vessel during three anticipated voyages within Australia, resulting in negligible to low risk outcomes. This finding is contrasted with expectations in the literature, specifically those that suggest slow moving vessels pose a high to extreme risk of transferring NIMS species.

The current study examines the cognitive supports that underlie achievement in science by using a cultural historical framework (L. S. Vygotsky (1934/1986), Thought and Language, MIT Press, Cambridge, MA.) and the activity setting (AS) construct (R. G. Tharp & R. Gallimore (1988), Rousing minds to life: Teaching, learning and schooling in social context, Cambridge University Press, Cambridge, MA.) with its five features: personnel, motivations, scripts, task demands, and beliefs. Observations were made of the classrooms of seventh-grade science students, 32 of whom had participated in a prior achievement-related parent-child interaction or home study (P. R. Portes, M. F. Zady, & R. M. Dunham (1998), Journal of Genetic Psychology, 159, 163-178). The results of a quantitative analysis of classroom interaction showed two features of the AS: personnel and scripts. The qualitative field analysis generated four emergent phenomena related to the features of the AS that appeared to influence student opportunity for conceptual development. The emergent phenomenon were science activities, the building of learning, meaning in lessons, and the conflict over control. Lastly, the results of the two-part classroom study were compared to those of the home science AS of high and low achievers. Mismatches in the AS features in the science classroom may constrain the opportunity to learn. Educational implications are discussed.

When the 135,000 cu m LNG carrier Al Zubarah departed Ras Laffan Port in December, Qatar entered a new era of commerce that will both boost the emirate`s economic development and influence energy trade around the world. The event capped more than a decade of planning, design, and construction of Ras Laffan Port--the world`s newest and largest LNG exporting facility. During the 1980s, the focus in Qatar was on exploration and development of North field, which holds the world`s largest reserves of nonassociated natural gas. In the 1990s, efforts concentrated on establishing a direct production and export link between Northmore » field, the new multi-billion-dollar Qatar Liquefied Gas Co. (Qatargas) gas liquefaction plant at Ras Laffan, and LNG export facilities at the 8.5 sq km Ras Laffan Port. Markets of the Far East will be first to be served by LNG from Ras Laffan Port. Two 25-year LNG supply contracts have been signed with buyers in Japan and South Korea, and negotiations are under way with potential customers from China, Taiwan, and Thailand.

Sediment Plumes Resulting from the Port of Miami Dredging: Analysis and Interpretation Using Satellite Data and Long Term Monitoring Programs

NASA Astrophysics Data System (ADS)

Barnes, B. B.; Hu, C.; Kovach, C.; Silverstein, R. N.

2016-02-01

From November 2013 through mid-2015, large turbidity plumes were observed offshore the Port of Miami (Florida, USA), likely associated with a project to deepen and widen the Miami Harbor channels. Using data from local monitoring programs, however, it is difficult to estimate the size, duration, extent, and severity (relative to natural turbidity events) of these plumes. In contrast, satellite observing systems offer a platform from which these plumes can be monitored and placed in historical context. As such, turbidity plumes captured by MODIS (Aqua) and Landsat 8 reflectance data were manually outlined. For MODIS, these delineations were refined using reflectance anomaly thresholds, determined from pre-dredging data. Long term records of local environmental conditions were used to account for conditions (e.g., wind speed, tidal stage) for which elevated reflectance data might be expected in the absence of dredging. The spatial extent of turbidity plumes observed in the Port of Miami region during the dredging period ranged from 127 and 228 km2, at least 5 times that immediately prior to dredging. The frequency of observed plumes in satellite imagery increased from 23% to 84% after dredging began, while temporal differences in plume location, severity, and size were also observed. Turbidity plumes may have large adverse effects on coral communities, and this region is home to many species of coral (including some considered threatened by the US Endangered Species Act). Indeed, over 11 km2 of coral area was affected by these plumes, with some locations within plume delineations on nearly 40% of images. The approaches developed in this work, in particular the focus on historical norms after considering all perturbation factors, may be included in monitoring and assessment of this and future dredging activities, especially where fragile marine ecosystems may potentially be impacted.

2002-02-01

A computer-based algorithm has been developed which uses preoperative images to provide a surgeon with a list of feasible port triplets ranked according to tool dexterity and endoscopic view quality at each surgical site involved in a procedure. A computer simulation allows the surgeon to select from among the proposed port locations. The procedure selected for the development of the system consists of a coronary artery bypass graft (CABG). In this procedure, the interior mammary artery (IMA) is mobilized from the interior chest wall, and one end is attached to the coronary arteries to provide a new blood supply for the heart. Approximately 10-20 cm is dissected free, using blunt dissection and a harmonic scalpel or electrocautery. At present, the port placement system is being evaluated in clinical trials.

Appraisal of Emissions from Ocean-going Vessels Coming to Kolkata Port, India

Rapid economic growth has escalated India's share in international trade. The pressure on these ports, which handle a substantial portion of the trade, has increased to perform with optimal efficiency, and decrease turnaround time so as to increase the number of ships visiting the port area. The caveat is that increased shipping activity is accompanied by enhanced emissions of harmful pollutants and green house gases. This study has revealed increased turnaround time for ships resulting in substantial emissions from auxiliary engines. There should be an optimum balance between operational control and environmental control of pollutants. Kolkata is a megacity with active riverine ports that can generate high levels of air quality emissions, especially NOx, SOx and particulate matter. An exhaustive annual emissions inventory based on ocean going vessels activity has been developed for 2013-2014 for Kolkata port, using recent EPA approved methodology. This includes greenhouse gas emissions from marine engines as well. The study indicates that amongst the different categories of ocean going ships, containers contribute the most (49%) of air and greenhouse gas emissions in 75th percentile class and above followed by general cargo (14%) and oil tankers (13%). The study depicts existing status of marine emissions in Kolkata port from ocean going vessels, which would serve in development of integrated air quality and climate change management plans and serve as a prototype for other major ports of India.

The 2-port laparoscopic appendectomy technique (TLA) is between the conventional 3-port and single-port laparoscopic appendectomy surgeries. We compared postoperative pain and cosmetic results after TLA with conventional laparoscopic appendectomy (CLA) by a 3-port device. Patients undergoing TLA were matched with patients undergoing CLA between February 2015 and November 2015 at the same institution. Thirty-two patients underwent TLA with a needle grasper. The appendix was secured by a percutaneous organ-holding device (needle grasper), then removed through a puncture at McBurney's point. Another 38 patients underwent CLA. Patient demographics, operative details, and postoperative outcomes were collected and evaluated. One patient in the TLA group developed a wound infection and 1 patient in the CLA group developed a postoperative intra-abdominal abscess and 3 wound infections. There was no significant difference between the groups when comparing the length of hospital stay, time until oral intake, and other complications. The pain score in the first 12 hours after surgery was significanly higher in CLA group than the TLA group (P < 0.001). Operative time was significantly shorter in the CLA group compared to the TLA group (P < 0.001). TLA using a needle grasper was associated with a significantly lower pain score 12 hours after surgery, better cosmetic results, and lower cost, than the CLA 3-port procedure because of the fewer number of ports.

Ultra-short silicon MMI duplexer

NASA Astrophysics Data System (ADS)

Yi, Huaxiang; Huang, Yawen; Wang, Xingjun; Zhou, Zhiping

2012-11-01

The fiber-to-the-home (FTTH) systems are growing fast these days, where two different wavelengths are used for upstream and downstream traffic, typically 1310nm and 1490nm. The duplexers are the key elements to separate these wavelengths into different path in central offices (CO) and optical network unit (ONU) in passive optical network (PON). Multimode interference (MMI) has some benefits to be a duplexer including large fabrication tolerance, low-temperature dependence, and low-polarization dependence, but its size is too large to integrate in conventional case. Based on the silicon photonics platform, ultra-short silicon MMI duplexer was demonstrated to separate the 1310nm and 1490nm lights. By studying the theory of self-image phenomena in MMI, the first order images are adopted in order to keep the device short. A cascaded MMI structure was investigated to implement the wavelength splitting, where both the light of 1310nm and 1490nm was input from the same port, and the 1490nm light was coupling cross the first MMI and output at the cross-port in the device while the 1310nm light was coupling through the first and second MMI and output at the bar-port in the device. The experiment was carried on with the SOI wafer of 340nm top silicon. The cascaded MMI was investigated to fold the length of the duplexer as short as 117μm with the extinct ratio over 10dB.

Chanchang, Chamchan; Sithisarankul, Pornchai; Supanitayanon, Thanawat

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.

Towards a Comparative Index of Seaport Climate-Risk: Development of Indicators from Open Data

NASA Astrophysics Data System (ADS)

McIntosh, R. D.; Becker, A.

2016-02-01

Seaports represent an example of coastal infrastructure that is at once critical to global trade, constrained to the land-sea interface, and exposed to weather and climate hazards. Seaports face impacts associated with projected changes in sea level, sedimentation, ocean chemistry, wave dynamics, temperature, precipitation, and storm frequency and intensity. Port decision-makers have the responsibility to enhance resilience against these impacts. At the multi-port (regional or national) scale, policy-makers must prioritize adaptation efforts to maximize the efficiency of limited physical and financial resources. Prioritization requires comparing across seaports, and comparison requires a standardized assessment method, but efforts to date have either been limited in scope to exposure-only assessments or limited in scale to evaluate one port in isolation from a system of ports. In order to better understand the distribution of risk across ports and to inform transportation resilience policy, we are developing a comparative assessment method to measure the relative climate-risk faced by a sample of ports. Our mixed-methods approach combines a quantitative, data-driven, indicator-based assessment with qualitative data collected via expert-elicitation. In this presentation, we identify and synthesize over 120 potential risk indicators from open data sources. Indicators represent exposure, sensitivity, and adaptive capacity for a pilot sample of 20 ports. Our exploratory data analysis, including Principal Component Analysis, uncovered sources of variance between individual ports and between indicators. Next steps include convening an expert panel representing the perspectives of multiple transportation system agencies to find consensus on a suite of robust indicators and metrics for maritime freight node climate risk assessment. The index will be refined based on expert feedback, the sample size expanded, and additional indicators sought from closed data sources. Developing standardized indicators from available data is an essential step in risk assessment, as robust indicators can help policy-makers monitor resilience strategy implementation, target and justify resource expenditure for adaptation schemes, communicate adaptation to stakeholders, and benchmark progress.

A Modeling Tool for Household Biogas Burner Flame Port Design

NASA Astrophysics Data System (ADS)

Decker, Thomas J.

Anaerobic digestion is a well-known and potentially beneficial process for rural communities in emerging markets, providing the opportunity to generate usable gaseous fuel from agricultural waste. With recent developments in low-cost digestion technology, communities across the world are gaining affordable access to the benefits of anaerobic digestion derived biogas. For example, biogas can displace conventional cooking fuels such as biomass (wood, charcoal, dung) and Liquefied Petroleum Gas (LPG), effectively reducing harmful emissions and fuel cost respectively. To support the ongoing scaling effort of biogas in rural communities, this study has developed and tested a design tool aimed at optimizing flame port geometry for household biogas-fired burners. The tool consists of a multi-component simulation that incorporates three-dimensional CAD designs with simulated chemical kinetics and computational fluid dynamics. An array of circular and rectangular port designs was developed for a widely available biogas stove (called the Lotus) as part of this study. These port designs were created through guidance from previous studies found in the literature. The three highest performing designs identified by the tool were manufactured and tested experimentally to validate tool output and to compare against the original port geometry. The experimental results aligned with the tool's prediction for the three chosen designs. Each design demonstrated improved thermal efficiency relative to the original, with one configuration of circular ports exhibiting superior performance. The results of the study indicated that designing for a targeted range of port hydraulic diameter, velocity and mixture density in the tool is a relevant way to improve the thermal efficiency of a biogas burner. Conversely, the emissions predictions made by the tool were found to be unreliable and incongruent with laboratory experiments.

Ship emissions contribute significantly to air pollution and impose health risks to residents along the coastal area. By using the refined data from the Automatic Identification System (AIS), this study developed a highly resolved ship emission inventory for the Pearl River Delta (PRD) region, China, home to three of ten busiest ports in the world. The region-wide SO 2 , NO X , CO, PM 10 , PM 2.5 , and VOC emissions in 2013 were estimated to be 61,484, 103,717, 10,599, 7155, 6605, and 4195t, respectively. Ocean going vessels were the largest contributors of the total emissions, followed by coastal vessels and river vessels. In terms of ship type, container ship was the leading contributor, followed by conventional cargo ship, dry bulk carrier, fishing ship, and oil tanker. These five ship types accounted for >90% of total emissions. The spatial distributions of emissions revealed that the key emission hot spots all concentrated within the newly proposed emission control area (ECA) and ship emissions within ECA covered >80% of total ship emissions in the PRD, highlighting the importance of ECA in emissions reduction in the PRD. The uncertainties of emission estimates of pollutants were quantified, with lower bounds of -24.5% to -21.2% and upper bounds of 28.6% to 33.3% at 95% confidence intervals. The lower uncertainties in this study highlighted the powerfulness of AIS data in improving ship emission estimates. The AIS-based bottom-up methodology can be used for developing and upgrading ship emission inventory and formulating effective control measures on ship emissions in other port regions wherever possible.

Inland waterway ports nodal attraction indices relevant in development strategies on regional level

NASA Astrophysics Data System (ADS)

Dinu, O.; Burciu, Ş.; Oprea, C.; Ilie, A.; Rosca, M.

2016-08-01

Present paper aims to propose a set of ranking indices and related criteria, concerning mainly spatial analysis, for the inland waterway port, with special view on inland ports of Danube. Commonly, the attraction potential of a certain transport node is assessed by its spatial accessibility indices considering both spatial features of the location provided by the networks that connect into that node and its economic potential defining the level of traffic flows depending on the economic centers of its hinterland. Paper starts with a overview of the critical needs that are required for potential sites to become inland waterway ports and presents nodal functions that coexist at different levels, leading to a port hierarchy from the points of view of: capacity, connection to hinterland, traffic structure and volume. After a brief review of the key inland waterway port ranking criterion, a selection of nodal attraction measures is made. Particular considerations for the Danube inland port case follows proposed methodology concerning indices of performance for network scale and centrality. As expected, the shorter the distance from an inland port to the nearest access point the greater accessibility. Major differences in ranking, dependent on selected criterion, were registered.

Planning for Resilient Settlement in Port Fairy, Australia

NASA Astrophysics Data System (ADS)

Tuntung Pandangwati, Sri

2017-07-01

This paper aims to discuss some strategies to address problems and challenges faced by a community living in Port Fairy, a coastal town located in Southwestern Victoria, Australia. It is about three hours’ drive from Melbourne’s CBD. Like other coastal towns, Port Fairy is also affected by climate change, severe weather events and sea level rise. The impact of these problems can be seen in East Beach, an important tourist destination in Port Fairy. Soil erosion and flood due to severe wind and wave, are main problems in East Beach. This will not only affect the housings, but also the landfill site located in this beach. Therefore, it is challenging to develop solutions to enhance the resilience of this coastal town. This study may inspire Indonesian planners to further develop the resilience of hundreds coastal towns in Indonesia.

PurposePlacement of peritoneal ports has become a favorable technique for direct chemotherapy infusion in treating peritoneal metastases from ovarian cancer. We aim to outline an approach to the percutaneous insertion of peritoneal ports and to characterize success and complication rates compared to surgically inserted ports.Materials and MethodsRetrospective analysis was collected from 87 patients who had peritoneal port insertion (28 inserted surgically and 59 percutaneously) for treatment of peritoneal metastases from ovarian cancer from July 2004 to July 2014. Complications were classified according to the SIR Clinical Practice Guidelines as major or minor.ResultsTechnical success rates for surgically and percutaneously inserted portsmore » were 100 and 96.7 %, respectively (p = 0.44), with the two percutaneous failures successful at a later date. There were no major complications in either group. Minor complication rates for surgically versus percutaneously inserted ports were 46.4 versus 22.0 %, respectively (p = 0.02). The infection rate for surgically inserted versus percutaneously inserted ports was 14.3 and 0 %, respectively (p = 0.002). The relative risk of developing a complication from percutaneous peritoneal port insertion without ascites was 3.4 (p = 0.04). For percutaneously inserted ports, the mean in-room procedure time was 81 ± 1.3 min and mean fluoroscopy time was 5.0 ± 4.5 min.ConclusionPercutaneously inserted peritoneal ports are a safe alternative to surgically inserted ports, demonstrating similar technical success and lower complication rates.« less

To examine whether the real-time ultrasound-guided venipuncture for implantable venous port placement is safer than the traditional venipuncture. The study analyzed the results of 2153 venous ports placed consecutively from January 2009 to January 2016. A total of 922 patients in group 1 and 1231 patients in group 2 were admitted with venous port placed using the traditional landmark subclavian approach and real-time ultrasound-guided axillary approach, respectively. Sociodemographic characteristics of patients, early (pneumothorax, pinch-off syndrome, arterial puncture, hematoma, and malposition arrhythmia) and late (deep vein thrombosis, obstruction, infection, erosion-dehiscence, and rotation of the port chamber) complications and the association of these complications with the implantation method were evaluated. There were no significant differences in the sociodemographic characteristics of the patients between the two groups. The overall and early complications in group 2 were significantly lower than those in group 1. Pinch-off syndrome only developed in group 1. Seven patients and two patients had pneumothorax in groups 1 and 2, respectively. Puncture number was significantly associated with the development of the overall complications. The ultrasound-guided axillary approach may be preferred as a method to reduce the risk of both early and late complications. Large, randomized, controlled prospective trials will be helpful in determining a safer implantable venous port implantation technique.

To introduce a novel method for the treatment of PPROM (preterm premature rupture of membranes) using continuous amnioinfusion via a subcutaneously implanted port system. After development and testing since 2001 in a fetal sheep model, the port system has been successfully implanted in two humans with PPROM. In the first case, the subcutaneous port system was implanted during the 23rd week of gestation in a 39-year-old 5th-gravida with PPROM since the 18th week of gestation; in the second case, the port system was implanted during the 24th week of gestation in a 27-year-old 3rd gravida with PPROM since the 21st week of gestation. After port implantation, 100ml/h saline solution was infused intermittently into the amniotic cavity. The whole course of treatment was supported by tocolysis. In the cases presented, gestation was terminated by cesarean section, in one case in the 29th week of gestation, and in the other case in the 30th week. The newborns showed no signs of lung hypoplasia and were successfully extubated on the 1st or 2nd day after delivery. Six months later the children did not exhibit any deviation from the normal development. Long-term amnioinfusion via a subcutaneously implanted port system could be used in humans with PPROM for prolongation of pregnancy and to avoid lung hypoplasia.

2017-12-01

The aim of this article is to reduce the risk of occupational hazards and improve safety conditions by enhancing hazard knowledge and identification as well as improving safety behavior for freight port enterprises. In the article, occupational hazards to health and their prevention measures of freight port enterprises have been summarized through a lot of occupational health evaluation work, experience and understanding. Workers of freight port enterprises confront an equally wide variety of chemical, physical and psychological hazards in production technology, production environment and the course of labor. Such health hazards have been identified, the risks evaluated, the dangers to health notified and effective prevention measures which should be put in place to ensure the health of the port workers summarized. There is still a long way to go for the freight port enterprises to prevent and control the occupational hazards. Except for occupational hazards and their prevention measures, other factors that influence the health of port workers should also be paid attention to, such as age, work history, gender, contraindication and even the occurrence and development rules of occupational hazards in current production conditions.

China is planning to develop a helium-cooled ceramic breeder (HCCB) test blanket module (TBM) on ITER to test key blanket technologies. In this paper, the design and tritium permeation analysis of China HCCB TBM port cell are introduced. A theoretical model has been developed to estimate tritium permeation rates and leak rates from the components and pipes which China has scheduled to house in the port cell. It is shown that on normal working conditions, the permeation and leak rate of the systems in the port cell will be no higher than 1.58 Ci/d without the use of tritium permeationmore » barriers, and 0.10 Ci/d with the use of tritium permeation barriers. It also appears that tritium permeation barriers are necessary for high temperature components such as the reduction bed and the heater.« less

Towards an Archaeology of Early Islamic Ports on the Western Red Sea Coast

Breen, Colin

2013-12-01

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.

On 12 January 2010 an earthquake measuring 7.0 on the Richter Scale struck Haiti, causing unprecedented death, injury and destruction for an event of this magnitude. Our aim was to generate a rapid assessment of the primary consequences for the population of the metropolitan area of Port-au-Prince, the national capital. During the summer of 2009 we conducted a survey of 1,800 households in metropolitan Port-au-Prince. Six weeks after the earthquake, we attempted to trace these households in order to re-interview them. The questionnaire examined mortality and injuries generated by the natural disaster, as well as the character of victimization, food security and living arrangements following the quake. Data analysis incorporated sampling weights and adjusted for clustering within households. The original 2009 survey featured a 90 per cent response rate; in 2010 we re-interviewed 93 per cent of these households. We estimate that 158,679 people in Port-au-Prince (95 per cent CI 136,813-180,545) died during the quake or in the six-week period afterwards owing to injuries or illness. Children were at particular risk for death. In the six weeks after the earthquake, 10,813 people (95 per cent CI 6,726-14,900) were sexually assaulted, the vast majority of whom were female. In the same period 4,645 individuals (95 per cent CI 1,943-7,347) were physically assaulted. Of all households, 18.6 per cent (95 per cent CI 16.6-20.8) were experiencing severe food insecurity six weeks after the earthquake. 24.4 per cent (95 per cent CI 22.1-26.9) of respondents' homes were completely destroyed. Many residents of Port-au-Prince died during or as a result of the earthquake, albeit fewer than were widely reported. More than half of the capital's population experienced moderate to severe food insecurity, though remittances are a major protective factor in promoting food security. Survivors continue to experience high levels of sexual assault and limited access to durable shelter.

Challenges in undertaking mosquito surveillance at UK seaports and airports to prevent the entry and establishment of invasive vector species.

Port health authorities have played an important role in the control of infectious diseases worldwide. The International Health Regulations (2005) further clarifies this role and provides a legal statutory instrument that aims to assist the international community to prevent and respond to global public health risks. Eleven UK sea and airports participated in a pilot, investigating the challenges ports could face in attempting to monitor for mosquitoes. The study also examined the types of habitat that could support mosquitoes. There is a concern that exotic vector species, such as Aedes albopictus, could invade and become established in the UK. Environments in and around the ports differed, and this was reflected in the species of mosquitoes caught. Ports used different methods to collect mosquitoes and developed a range of techniques for surveying, which suited the conditions at their port. This paper discusses the implications of invasive mosquito surveillance to UK port health authorities.

We have previously reported our technique of single-docking totally robotic dissection for rectal cancer surgery using the Da Vinci ® Si Surgical System in 2009. However, we have since optimised our port placement for the Si system and have developed a novel configuration of port placement and docking for the Da Vinci ® Xi Surgical System. We have performed over 700 cases using this technique with the Si system and have used our Xi technique since 2016 for totally robotic dissection for rectal cancer. We have kept the configuration of port placements for both the Xi and Si system as similar as possible, with the priorities to avoid arm collisions as well as to provide a workable port configuration of two left-handed instruments and one right-handed instrument. To date, there have had no major complications or arm collisions related to this technique of docking, port positioning and instrument placement.

The city of Jeddah is the second largest city in Saudi Arabia (after Riyadh), and is the country’s most important Red Sea port. A large warehouse and dock complex is visible in the lower left portion of this image. Apart from being a major port for exchange of goods with Africa and Europe, Jeddah is of great importance for Islamic pilgrims going east to Mecca (a religious journey known as the hajj). In addition to urban attractions, coral reefs along the coast (north-south trending islands to image left) are frequented by divers visiting the city. The image captures the multicolored rooftops of homes and other buildings in the city, the oldest of which were built using coral from the nearby Red Sea and clay from the al-Manqabah lagoon in the center of the Al Balad district (center of image; lagoon is approximately 0.25 km across).

Unclosed fascial defect: is it the risk to develop port-site hernia after laparoscopic cholecystectomy?

PubMed

Tangjaroen, Somard; Watanapa, Prasit

2014-02-01

Port-site hernia (PSH) is one of the complications after laparoscopic cholecystectomy (LC). Closure of the fascial defect has been mentioned to prevent such complication. However, the results are still controversial. The present study was done to clarify whether unclosed fascial defect was actually the risk factor for the development of PSH MATERIAL AND METHOD: Two hundred ninety four patients underwent LC by a single surgeon at Kalasin Hospital between 2007 and 2010. The procedure was done by using a four-port technique without closure of any fascial defects. The male:female ratio was 85:209, and the mean body mass index was 24.38 +/- 3.33 (SD). The mean operative time was 18.71 +/- 3.76 minutes and there was no postoperative wound infection. Patients were regularly followed-up and underwent both supine and upright physical examination. The mean duration of follow-up period was 4.94 +/- 1.31 years with the shortest follow-up period of two years. None of the patients in the present study developed PSH in any port sites during the follow-up period. Unclosed fascial defect may not have the significant risk factor of developing PSH after LC.

Design and evaluation of candidate pressure ports for the HYFLITE experiment

Teter, John E., Jr.; Cleckner, Craig S.; Vontheumer, Alfred E.

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.

Single-port access laparoscopic hysterectomy: a new dimension of minimally invasive surgery.

Liliana, Mereu; Alessandro, Pontis; Giada, Carri; Luca, Mencaglia

2011-01-01

The fundamental idea is to have all of the laparoscopic working ports entering the abdominal wall through the same incision. Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus and reduces morbidity of minimally invasive surgery. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. This review summarizes the history of SPAL hysterectomy (single-port access laparoscopy), and emphasizes nomenclature, surgical technique, instrumentation, and perioperative outcomes. Specific gynecological applications of single-port hysterectomy to date are summarized. Using the PubMed database, the English-language literature was reviewed for the past 40 years. Keyword searches included scarless, scar free, single-port/trocar/incision, single-port access laparoscopic hysterectomy. Within the bibliography of selected references, additional sources were retrieved. The purpose of the present article was to review the development and current status of SPAL hysterectomy and highlight important advances associated with this innovative approach.

Female sterilisation by tubal occlusion method by laparocator is most widely used and accepted technique of all family planning measures all over the world. After the development of laparoscopic surgery in all faculties of surgery by monitor, now laparoscopic female sterilisation has been developed to do under monitor control by two ports--one for laparoscope and second for ring applicator. But the technique has been modified using single port with monitor through laparocator in which camera is fitted on the eye piece of laparocator (the same laparocator which is commonly used in camps without monitor since a long time in India). In this study over a period of about 2 years, a total 2011 cases were operated upon. In this study, I used camera and monitor through a single port by laparocator to visualise as well as to apply ring on fallopian tubes. The result is excellent and is a better alternative to conventional laparoscopic sterilisation and double puncture technique through camera--which give two scars and an extra assistant is required. However, there was no failure and the strain on surgeon's eye was minimum. Single port is much easier, safe, equally effective and better acceptable method.

This report outlines the activities undertaken by the Inter-PORT Dissemination work group during its first 2 years of operation. The work group's initial purpose was to assist the individual PORTs in developing their plans for both disseminating research findings and evaluating the effectiveness of these strategies. However, it became quickly apparent that in a discipline little more than a decade old, a commonly understood vocabulary had yet to be adopted. Even the term "dissemination" held different meaning for different constituencies. Consequently, the work group has tried to encourage the development of both a definitional framework and a set of common data elements of importance to all dissemination programs. The work group has analogously attempted to agree on minimum standards of methodologic rigor as a starting point for coordination of evaluations across PORTs. To help determine the potential for further coordination, a matrix of each individual PORT's target audiences, intervention strategies, and evaluation designs has been constructed. Much remains to be learned before we can know with any certainty how best to translate research findings into useful behavior change and improved patient outcomes. Our goal is that the efforts of the work group will serve to catalyze this process.

The main objective of this study is presenting a real-time mobile adaptive tracking system for patients diagnosed with diseases such as asthma or chronic obstructive pulmonary disease and application results at home. The main role of the system is to support and track chronic pulmonary patients in real time who are comfortable in their home environment. It is not intended to replace the doctor, regular treatment, and diagnosis. In this study, the Java 2 micro edition-based system is integrated with portable spirometry, smartphone, extensible markup language-based Web services, Web server, and Web pages for visualizing pulmonary function test results. The Bluetooth(®) (Bluetooth SIG, Kirkland, WA) virtual serial port protocol is used to obtain the test results from spirometry. General packet radio service, wireless local area network, or third-generation-based wireless networks are used to send the test results from a smartphone to the remote database. The system provides real-time classification of test results with the back propagation artificial neural network algorithm on a mobile smartphone. It also provides the generation of appropriate short message service-based notification and sending of all data to the Web server. In this study, the test results of 486 patients, obtained from Atatürk Chest Diseases and Thoracic Surgery Training and Research Hospital in Ankara, Turkey, are used as the training and test set in the algorithm. The algorithm has 98.7% accuracy, 97.83% specificity, 97.63% sensitivity, and 0.946 correlation values. The results show that the system is cheap (900 Euros) and reliable. The developed real-time system provides improvement in classification accuracy and facilitates tracking of chronic pulmonary patients.

This procedure combines rigorously selected parameters and indicators to estimate the environmental risk of each contaminant source based on its probability, consequences and vulnerability. The spatio-temporal variability of multiple stressors (agents) and receptors (endpoints) is taken into account to provide accurate estimations for application of precisely defined measures. The developed methodology is tested on a wide range of different scenarios via application in six European ports. The validation process confirms its usefulness, versatility and adaptability as a management tool for port water quality in Europe and worldwide. Copyright © 2015 Elsevier Ltd. All rights reserved.

Technology Cost and Schedule Estimation (TCASE) Final Report

2015-01-01

During the 2014-2015 project year, the focus of the TCASE project has shifted from collection of historical data from many sources to securing a data pipeline between TCASE and NASA's widely used TechPort system. TCASE v1.0 implements a data import solution that was achievable within the project scope, while still providing the basis for a long-term ability to keep TCASE in sync with TechPort. Conclusion: TCASE data quantity is adequate and the established data pipeline will enable future growth. Data quality is now highly dependent the quality of data in TechPort. Recommendation: Technology development organizations within NASA should continue to work closely with project/program data tracking and archiving efforts (e.g. TechPort) to ensure that the right data is being captured at the appropriate quality level. TCASE would greatly benefit, for example, if project cost/budget information was included in TechPort in the future.

The Great Barrier Reef (GBR) region of Queensland, Australia, encompasses a complex and diverse array of tropical marine ecosystems of global significance. The region is also a World Heritage Area and largely within one of the world's best managed marine protected areas. However, a recent World Heritage Committee report drew attention to serious governance problems associated with the management of ports and shipping. We review the impacts of ports and shipping on biodiversity in the GBR, and propose a series of guiding principles to improve the current governance arrangements. Implementing these principles will increase the capacity of decision makers to minimize the impacts of ports and shipping on biodiversity, and will provide certainty and clarity to port operators and developers. A 'business as usual' approach could lead to the GBR's inclusion on the List of World Heritage in Danger in 2014. Copyright © 2013 Elsevier Ltd. All rights reserved.

Huang, H K

2011-07-01

The concept of PACS (picture archiving and communication system) was initiated in 1982 during the SPIE medical imaging conference in New Port Beach, CA. Since then PACS has been matured to become an everyday clinical tool for image archiving, communication, display, and review. This paper follows the continuous development of PACS technology including Web-based PACS, PACS and ePR (electronic patient record), enterprise PACS to ePR with image distribution (ID). The concept of large-scale Web-based enterprise PACS and ePR with image distribution is presented along with its implementation, clinical deployment, and operation. The Hong Kong Hospital Authority's (HKHA) integration of its home-grown clinical management system (CMS) with PACS and ePR with image distribution is used as a case study. The current concept and design criteria of the HKHA enterprise integration of the CMS, PACS, and ePR-ID for filmless healthcare delivery are discussed, followed by its work-in-progress and current status.

Single-port versus conventional multiport access prophylactic laparoscopic bilateral salpingo-oophorectomy in high-risk patients for ovarian cancer: a comparison of surgical outcomes

2015-01-01

Bilateral salpingo-oophorectomy (BSO) in carriers of BRCA1 and BRCA2 mutations is widely recommended as part of a risk-reduction strategy for ovarian or breast cancer due to an underlying genetic predisposition. BSO is also performed as a therapeutic intervention for patients with hormone-positive premenopausal breast cancer. BSO may be performed via a minimally invasive approach with the use of three to four 5 mm and/or 12 mm ports inserted through a skin incision. To further reduce the morbidity associated with the placement of multiple port sites and to improve cosmetic outcomes, single-port laparoscopy has been developed with a single access point from the umbilicus. The purpose of this study was to evaluate the surgical outcomes associated with reducing the risks of salpingo-oophorectomy performed in a single port, while comparing multiport laparoscopy in women with a high risk for ovarian cancer. Single-port laparoscopy–BSO is feasible and safe, with favorable surgical and cosmetic outcomes when compared to conventional laparoscopy. PMID:26170692

Puig, Martí; Wooldridge, Chris; Darbra, Rosa Mari

2014-04-15

In this paper an identification and selection of Environmental Performance Indicators (EPIs) in port areas has been conducted. A comprehensive inventory of existing EPIs in use in the seaport sector has been identified for monitoring performance of operational (e.g. dust, noise, dredging, and waste), managerial (e.g. certification, compliance, and complaints) and environmental condition (e.g. air, water, sediment and ecosystems). These indicators have been filtered against specific criteria and have been assessed and evaluated by port stakeholders in order to obtain a final set of indicators suitable to be implemented at EU level. A user friendly tool has been developed specifically to assist port authorities in calculating and reporting the proposed indicators. This study has drawn on major research projects to blend academic research with input from marine professionals in order to identify, select, evaluate and validate EPIs that are acceptable and feasible to the sector, and practicable in their application and implementation.

Artificial Neural Network forecasting of storm surge water levels at major estuarine ports to supplement national tide-surge models and improve port resilience planning

NASA Astrophysics Data System (ADS)

French, Jon; Mawdsley, Robert; Fujiyama, Taku; Achuthan, Kamal

2017-04-01

Effective prediction of tidal storm surge is of considerable importance for operators of major ports, since much of their infrastructure is necessarily located close to sea level. Storm surge inundation can damage critical elements of this infrastructure and significantly disrupt port operations and downstream supply chains. The risk of surge inundation is typically approached using extreme value analysis, while short-term forecasting generally relies on coastal shelf-scale tide and surge models. However, extreme value analysis does not provide information on the duration of a surge event and can be sensitive to the assumptions made and the historic data available. Also, whilst regional tide and surge models perform well along open coasts, their fairly coarse spatial resolution means that they do not always provide accurate predictions for estuarine ports. As part of a NERC Environmental Risks to Infrastructure Innovation Programme project, we have developed a tool that is specifically designed to forecast the North Sea storm surges on major ports along the east coast of the UK. Of particular interest is the Port of Immingham, Humber estuary, which handles the largest volume of bulk cargo in the UK including major flows of coal and biomass for power generation. A tidal surge in December 2013, with an estimated return period of 760 years, partly flooded the port, damaged infrastructure and disrupted operations for several weeks. This and other recent surge events highlight the need for additional tools to supplement the national UK Storm Tide Warning Service. Port operators are also keen to have access to less computationally expensive forecasting tools for scenario planning and to improve their resilience to actual events. In this paper, we demonstrate the potential of machine learning methods based on Artificial Neural Networks (ANNs) to generate accurate short-term forecasts of extreme water levels at estuarine North Sea ports such as Immingham. An ANN is configured to take advantage of far-field information on developing tidal surges provided by tide gauges in NW Scotland (the 'external surge'), supported by observations of wind and atmospheric pressure and the predicted astronomical tide at Immingham. Missing data can cause problems with ANN models and a novel aspect of our implementation is the use of multiple redundant inputs (nearby tide gauges that experience a high degree of surge coherence) to synthesise a single external surge input. A similar approach is taken with meteorological forcings, creating an ANN that is resilient against data drop-outs within its input vector. The ANN generates 6 to 24 hour surge forecasts at Immingham with accuracy better than the present UK Storm Tide Warning Service. These can be used to cross-check national forecasts, generate more accurate estimates of likely flood depths, timings and durations and trigger planned responses to severe forecasts. Crucially, this capability can be 'owned' by the port operator, which encourages the development of a shared understanding of storm surge hazards and the challenges of port resilience planning between scientist and stakeholder.

Properties of particulate pollution in the port city of Valparaiso, Chile

The city of Valparaiso is home to one of the largest commercial ports on the west coast of South America. Port activities, that continue year-round, 24 h a day and seven days a week, produce emissions of pollutants, particularly aerosol particles composed of black and brown carbon (BC and BrC) that have serious impact on human population and the local environment. A measurement program was launched to document the magnitude of selected pollutants, to identify their sources and to evaluate the meteorological processes that enhance and transport these pollutants locally and regionally. In this study, we report the measurements made during four months: 25July - 25August 2014 (referred to as August 2014 throughout the manuscript), December 2014, January 2015 and March 2015. The daily mass concentrations of equivalent black carbon (eBC), derived from measurements of the light absorption coefficient, regularly exceed 5 μg m-3, a magnitude similar to values found in megacities such as Mexico City. The daily maximum number concentration of condensation nuclei (CN) is usually larger than 30000 cm-3. The Angstrom absorption exponent (AAE), derived from the absorption coefficients at 550 nm and 870 nm, is used to identify the primary sources of BC and BrC. In colder weather, emissions from the diesel fueled buses and trucks and the consumption of kerosene and wood for residential heating are the main sources of BC. In December, local wildfires contributed to the particle mass loading, but the day-to-day variability in boundary layer height and the presence of clouds and fog in occasions inhibited high concentrations. In March, the port activities reach a yearly peak during the seasonal export of agricultural products that translates into much more ship and truck traffic leading to very high eBC concentrations, comparable to values observed during August. The variability in weather patterns underscores the complexity of meteorological processes that drive the evolution and transport of pollution in Valparaiso.

We sought to compare the outcomes of two chronic vascular access techniques, the externalized catheter and the subcutaneous vascular access port, in pigs. Female farm pigs (n = 30) underwent placement of a chronic vascular access device in the jugular vein for a research protocol: 18 of the animals underwent placement of a tunneled Hickman catheter (THC), and the remaining 12 animals underwent placement of a subcutaneous vascular access port (VAP) without external components. After placement of the devices, animals underwent serial blood sampling. All animals were given identical antibiotic prophylaxis. VAP access required the use of a restraint sling for Huber needle insertion, whereas THC access required no additional equipment. Animals were euthanatized 1 month after placement of the device. In the VAP group, the port was retrieved, cleaned, and steam-autoclaved for reuse. In the THC group, 13 (72%) animals developed infectious complications, and blood and wound cultures were often polymicrobial. One animal was euthanatized secondary to overwhelming sepsis. In addition, three (17%) animals developed thromboembolic complications. In contrast, no thromboembolic complications were noted in the VAP group, and only one animal developed a transient fever which resolved spontaneously; no septic complications or abscesses developed. Blood draws with no anesthesia were successful in both groups. We conclude that subcutaneous vascular access ports are a safe and efficient method for obtaining reliable chronic vascular access for a 1-month period in pigs. The subcutaneous devices were associated with low morbidity. In contrast, externalized catheters can be associated with considerable morbidity.

Risk Reduction of an Invasive Insect by Targeting Surveillance Efforts with the Assistance of a Phenology Model and International Maritime Shipping Routes and Schedules.

Reducing the risk of introduction to North America of the invasive Asian gypsy moth (Lymantria dispar asiatica Vnukovskij and L. d. japonica [Motschulsky]) on international maritime vessels involves two tactics: (1) vessels that wish to arrive in Canada or the United States and have visited any Asian port that is subject to regulation during designated times must obtain a predeparture inspection certificate from an approved entity; and (2) vessels with a certificate may be subjected to an additional inspection upon arrival. A decision support tool is described here with which the allocation of inspection resources at North American ports can be partitioned among multiple vessels according to estimates of the potential onboard Asian gypsy moth population and estimates of the onboard larval emergence pattern. The decision support tool assumes that port inspection is uniformly imperfect at the Asian ports and that each visit to a regulated port has potential for the vessel to be contaminated with gypsy moth egg masses. The decision support tool uses a multigenerational phenology model to estimate the potential onboard population of egg masses by calculating the temporal intersection between the dates of port visits to regulated ports and the simulated oviposition pattern in each port. The phenological development of the onboard population is simulated each day of the vessel log until the vessel arrives at the port being protected from introduction. Multiple independent simulations are used to create a probability distribution of the size and timing of larval emergence. © 2015 Society for Risk Analysis.

Enhancing Lipoaspirate Efficiency by Altering Liposuction Cannula Design

PubMed Central

Davis, Kathryn; Rohrich, Rod J.

2014-01-01

Background: Interplay between the components of a lipoplasty system (suction pump, suction tubing, collection canister, and cannula) determines liposuction efficiency. However, in clinical practice, none of the components are more important than the cannula. Cannula design including port design, port placement, and shaft characteristics is the single most influential contributor to flow resistance and dramatically effects speed of aspiration and final contour. Many variations on port design and placement are available, yet functional enhancements to the cannula shaft have largely been ignored. We have engineered a set of novel cannulas addressing vital elements of cannula design in the effort to enhance aspiration efficiency and efficacy. Methods: Two novel cannula designs (dual- and multiport, in-line configuration), created using a unique proprietary manufacturing process, were evaluated against a popular industry standard design (tri-port, Mercedes configuration) to assess aspiration efficiency. Cannulas with shaft diameters of 3, 4, and 5 mm were attached to a standardized lipoplasty system and evaluated in real time for their ability to aspirate a viscous applesauce medium over a 5-minute time course. For each cannula, we calculated (1) the cross-sectional area of the cannula shaft, (2) single and total port area, (3) port-to-shaft ratio, and (4) theoretical resistance. Results: The relationship between the cannula shaft and cannula port(s) directly influenced flow dynamics. Comparing medium uptake time, aspiration efficiency and the aspiration curves demonstrated a significant improvement of the 2 novel cannulas over the standard cannula in the 5- and 4-mm designations. In the 3-mm group, a difference in uptake time remained. However, a significant difference in aspiration efficiency was only seen between the dual-port novel cannula and tri-port Mercedes standard cannula. Further, differences in the aspiration curves between all 3-mm cannulas approached but did not reach significance. Conclusions: We have developed 2 novel cannulas that maximize port features and seek to minimize the internal shaft resistance. Both designs demonstrate enhanced aspiration and uptake compared with an industry standard design. PMID:25426339

The impact of the port of Santos, Brazil, on the population's health is unknown. We aimed to evaluate the association between living near the port area and physical inactivity and sedentary behavior. Cross-sectional study developed at a university laboratory and a diagnostic clinic. 553 healthy adults were selected and their level of physical activity in daily life was assessed using accelerometers. Multiple linear and logistic regressions were performed using physical inactivity and sedentary behavior as the outcomes and living near the port area as the main risk factor, with adjustments for the main confounders. Among all the participants, 15% were resident near the port area. They took 699 steps/day and presented, weekly, 2.4% more sedentary physical activity, 2.0% less time in standing position and 0.9% more time lying down than residents of other regions. Additionally, living near the port area increased the risk of physical inactivity by 2.50 times and the risk of higher amounts of sedentary behavior (≥ 10 hours/day) by 1.32 times. Living near the port of Santos is associated with physical inactivity and higher sedentary behavior among adults, regardless of confounders. The reasons for this association should be investigated in longitudinal studies.

Minimally invasive surgery has replaced median sternotomy for resectable anterior mediastinal masses and is performed by various approaches. We developed a new minimally invasive surgical procedure by combining the subxiphoid approach performed through a midline camera port with the use of a robotic surgery system (Intuitive Surgical, Sunnyvale, CA, USA). A 3-cm transverse incision was made 1 cm below the xiphoid process. Then, a port designed for single-port surgery was inserted. Through this port, CO2 gas was injected at 8 mmHg. The thymus was then detached from the back of the sternum. A 1-cm skin incision was made bilaterally in the sixth intercostal space, followed by insertion of a port for the robotic system. A camera port was inserted into the subxiphoid port, to which the camera scope was mounted, and thymectomy was performed. We have performed the operation in 3 patients. In our experience, this procedure provides a good operative view in the neck region and makes verification of the phrenic nerve easy. Furthermore, with the da Vinci surgical system, which enables surgical manipulation from a correct angle due to the multijoint robotic arms, trans-subxiphoid robotic thymectomy may be a promising new thymectomy procedure. © The Author 2015.

Ports are a key factor in the understanding and solving of most problems associated with marine invasive species across regional and global scales. Yet many regions with active ports remain understudied. The aim of this work was to (a) identify and quantify the marine fouling organisms in all Patagonian ports of Argentina classifying them as native, exotic or cryptogenic species through a rapid assessment survey and experimental studies, (b) survey the environmental and anthropogenic variables of these ports and (c) analyze and discuss these results in the light of the South America context for the study of marine invasive species, legislation and commerce. We found 247 fouling species, including 17 introduced, one of which is a new record for the region, and other 15 species currently considered cryptogenic species that will need further attention to clarify their status. The analysis of mobile and sessile taxa, together with the environmental variables measured in this study and the port movement, allow us to discuss individual ports' vulnerability to future introductions. This is the first large scale study performed for this region on this topic, and it will help in developing monitoring programs and early detection plans to minimize new species introductions along the marine coastline of southern South America.

[An atraumatic needle for the puncture of ports and pumps].

PubMed

Haindl, H; Müller, H

1988-10-17

Huber-point needles have been found to induce substantial coring during puncture of ports or pumps, which may lead to leakage or obturation of these devices. Therefore, different types of cannulas were tested in order to evaluate their applicability for this purpose. Pencil-point needles led to increased pain during puncture and thus seemed unsuitable. A newly developed port-cannula bent inwards within the length of the bevel ("protected bevel") and proved to be definitely noncoring during electron microscopy. Consequently the force required to introduce this needle was reduced by 50% in comparison with the Huber-type needle. In addition, this cannula allowed up to 3000 punctures of one port without leakage and, thus, correspondingly therefore relevantly increased the durability of this device.

The aim of this study was to evaluate a novel ultrasound probe specifically developed for robotic surgery by determining its efficiency in identifying renal tumors. The study was carried out using the Da Vinci™ surgical system in one female pig. Renal tumor targets were created by percutaneous injection of a tumor mimic mixture. Single-port and standard robotic partial nephrectomy were performed. Intraoperative ultrasound was performed using both standard laparoscopic probe and the new ProART™ Robotic probe. Probe maneuverability and ease of handling for tumor localization were recorded. The standard laparoscopic probe was guided by the assistant. Significant clashing with robotic arms was noted during the single-port procedure. The novel robotic probe was easily introduced through the assistant trocar, and held by the console surgeon using the robotic Prograsp™ with no registered clashing in the external operative field. The average time for grasping the new robotic probe was less than 10 s. Once inserted and grasped, no limitation was found in terms of instrument clashing during the single-port procedure. This novel ultrasound probe developed for robotic surgery was noted to be user-friendly when performing porcine standard and especially single-port robotic partial nephrectomy.

2017-03-01

The risk of port-site metastasis after laparoscopic removal of incidental gallbladder cancer was previously estimated to be 14-30%. The present study was designed to determine the incidence of port-site metastasis in incidental gallbladder cancer in the modern era (2000-2014) versus the historic era (1991-1999). We also investigated the site of port-site metastasis. Using PRISMA, a systematic review was conducted to identify papers that addressed the development of port-site metastasis after laparoscopic resection of incidental gallbladder cancer. Studies that described cancer-specific outcomes in ≥5 patients were included. A validated quality appraisal tool was used, and a weighted estimate of the incidence of port-site metastasis was calculated. Based on data extracted from 27 papers that met inclusion criteria, the incidence of port-site metastasis in incidental gallbladder cancer has decreased from 18.6% prior to 2000 (95% confidence interval 15.3-21.9%, n = 7) to 10.3% since then (95% confidence interval 7.9-12.7%, n = 20) (P < .001). The extraction site is at significantly higher risk than nonextraction sites. The incidence of port-site metastasis in incidental gallbladder cancer has decreased but remains high relative to other primary tumors. Any preoperative finding that raises the suspicion of gallbladder cancer should prompt further investigation and referral to a hepato-pancreato-biliary specialist. Copyright © 2016 Elsevier Inc.

Totally implantable port systems are generally recommended for prolonged central venous access in diverse settings, but their risk of complications remains unclear for patients with advanced cancer. The aim of this study was to assess the risk of port system failure in patients with advanced cancer. We conducted a retrospective cohort study in a comprehensive cancer centre. A detailed chart review was conducted among 566 patients with 573 ports inserted during January-June, 2009 (average 345.3 catheter-days). Cox regression analysis was applied to evaluate factors during insertion and early maintenance that could lead to premature removal of the port systems due to infection or occlusion. Port system-related infection was significantly associated with receiving palliative care immediately after implantation (hazard ratio, HR = 7.3, 95% confidence interval, 95% CI = 1.2-46.0), after adjusting for probable confounders. Primary cancer site also impacted the occurrence of device-related infection. Receiving oncologic/palliative care (HR = 3.0, P = 0.064), advanced cancer stage (HR = 6.5, P = 0.077) and body surface area above 1.71 m(2) (HR = 3.4, P = 0.029) increased the risk of port system occlusion. Our study indicates that totally implantable port systems yield a higher risk of complications in terminally ill patients. Further investigation should be carefully conducted to compare outcomes of various central venous access devices in patients with advanced cancer and to develop preventive strategies against catheter failure.

Sexuality behavior amongst young people in Nigeria and indeed Sub-Saharan Africa is seriously going through transformation from what it was previously. It is therefore important that young people have adequate information about their sexuality so that they can make informed choices. To determine perceptions and knowledge of sexuality education amongst secondary school students in Port Harcourt, Nigeria. A structured, anonymous and self-administered questionnaire, used as instrument for data collection, was distributed amongst a convenient sample of 1050 secondary school students attending a series of Schools debates in Port Harcourt Metropolis. The students were aged 10 -20 years, with a median age of 15. There were 486 males and 564 females giving a M: F ratio of 1:1.2. Four hundred and fourteen (73.4%) of the females had attained menarche. Nine hundred and fifty (90.5%) of the respondents had heard of sexuality education but only 422 (40.1%) discussed relevant topics on the subject. 52.8% believed that sexuality education should be given at home by both parents. However, only 164 (31.2%) and 19 (3.6%) got such information from their mothers and fathers respectively. Only 7.6% acknowledged the school teacher as a source of information. Secondary school students are aware of the subject of sexuality education, but lack adequate information on sexuality issues. Parents and teachers are a poor source of information for students. Parents, Teachers and students need to be enlightened on sexuality education. There is also a need to incorporate it into the school curriculum.

The purpose of this study was to determine the incidence of central vein stenosis and occlusion following upper extremity placement of peripherally inserted central venous catheters(PICCs) and venous ports. One hundred fifty-four patients who underwent venography of the ipsilateral central veins prior to initial and subsequent venous access device insertion were retrospectively identified. All follow-up venograms were interpreted at the time of catheter placement by one interventional radiologist over a 5-year period and compared to the findings on initial venography. For patients with central vein abnormalities, hospital and home infusion service records and radiology reports were reviewed to determine cathetermore » dwelltime and potential alternative etiologies of central vein stenosis or occlusion. The effect of catheter caliber and dwell time on development of central vein abnormalities was evaluated. Venography performed prior to initial catheter placement showed that 150 patients had normal central veins. Three patients had central vein stenosis, and one had central vein occlusion. Subsequent venograms (n = 154)at the time of additional venous access device placement demonstrated 8 patients with occlusions and 10 with stenoses. Three of the 18 patients with abnormal follow-up venograms were found to have potential alternative causes of central vein abnormalities. Excluding these 3 patients and the 4 patients with abnormal initial venograms, a 7% incidence of central vein stenosis or occlusion was found in patients with prior indwelling catheters and normal initial venograms. Catheter caliber showed no effect on the subsequent development of central vein abnormalities. Patients who developed new or worsened central vein stenosis or occlusion had significantly (p =0.03) longer catheter dwell times than patients without central vein abnormalities. New central vein stenosis or occlusion occurred in 7% of patients following upper arm placement of venous access devices.Patients with longer catheter dwell time were more likely to develop central vein abnormalities. In order to preserve vascular access for dialysis fistulae and grafts and adhere to Dialysis Outcomes Quality Initiative guidelines, alternative venous access sites should be considered for patients with chronic renal insufficiency and end-stage renal disease.« less

Stakeholder identification of advanced technology opportunities at international ports of entry

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

Parker, S.K.; Icerman, L.

As part of the Advanced Technologies for International and Intermodal Ports of Entry (ATIPE) Project, a diverse group of stakeholders was engaged to help identify problems experienced at inland international border crossings, particularly those at the US-Mexican border. The fundamental issue at international ports of entry is reducing transit time through the required documentation and inspection processes. Examples of other issues or problems, typically manifested as time delays at border crossings, repeatedly mentioned by stakeholders include: (1) lack of document standardization; (2) failure to standardize inspection processes; (3) inadequate information and communications systems; (4) manual fee and tariff collection; (5)more » inconsistency of processes and procedures; and (6) suboptimal cooperation among governmental agencies. Most of these issues can be addressed to some extent by the development of advanced technologies with the objective of allowing ports of entry to become more efficient while being more effective. Three categories of technologies were unambiguously of high priority to port of entry stakeholders: (1) automated documentation; (2) systems integration; and (3) vehicle and cargo tracking. Together, these technologies represent many of the technical components necessary for pre-clearance of freight approaching international ports of entry. Integration of vehicle and cargo tracking systems with port of entry information and communications systems, as well as existing industry legacy systems, should further enable border crossings to be accomplished consistently with optimal processing times.« less

Breithaupt, Stephen A.; Copping, Andrea; Tagestad, Jerry

2016-09-28

This study examines maritime routes between ports along the Atlantic coast of the US, utilising Automated Identification System (AIS) data for the years 2010 through 2012. The delineation of vessel routes conducted in this study was motivated by development planned for offshore Wind Energy Areas (WEAs) along the Atlantic coast of the US and the need to evaluate the effect of these development areas on commercial shipping. To this end, available AIS data were processed to generate commercial vessel tracks for individual vessels, though cargo vessels are the focus in this study. The individual vessel tracks were sampled at transectsmore » placed along the Atlantic coast. The transect samples were analysed and partitioned by voyages between Atlantic ports to facilitate computation of vessel routes between ports. The route boundary analysis utilised a definition from UK guidance in which routes' boundaries encompassed 95% of the vessel traffic between ports. In addition to delineating route boundaries, we found multi-modal transverse distributions of vessels for well-travelled routes, which indicated preference for lanes of travel within the delineated routes.« less

To evaluate the clinical outcomes and complications of totally implantable venous access port implantation via the axillary vein in patients with head and neck malignancy. A total of 176 totally implantable venous access ports were placed via the axillary vein in 171 patients with head and neck malignancy between May 2012 and June 2015. The patients included 133 men and 38 women, and the mean age was 58.8 years (range: 19-84 years). Medical records were retrospectively reviewed. This study included a total of 93,237 totally implantable venous access port catheter-days (median 478 catheter-days, range: 13-1380 catheter-days). Of the 176 implanted totally implantable venous access port, complications developed in nine cases (5.1%), with the overall incidence of 0.097 events/1000 catheter-days. The complications were three central line-associated blood-stream infection cases, one case of keloid scar at the needling access site, and five cases of central vein stenosis or thrombosis on neck computed tomography images. The 133 cases for which neck computed tomography images were available had a total of 59,777 totally implantable venous access port catheter-days (median 399 catheter-days, range: 38-1207 catheter-days). On neck computed tomography evaluation, the incidence of central vein stenosis or thrombosis was 0.083 events/1000 catheter-days. Thrombosis developed in four cases, yielding an incidence of 0.067 events/1000 catheter-days. All four patients presented with thrombus in the axillary or subclavian vein. Stenosis occurred in one case yielding an incidence of 0.017 events/1000 catheter-days. One case was catheter-related brachiocephalic vein stenosis, and the other case was subclavian vein stenosis due to extrinsic compression by tumor progression. Of the nine complication cases, six underwent port removal. These data indicate that totally implantable venous access port implantation via the axillary vein in patients with head and neck malignancy is safe and feasible, with a low axillary vein access-related complication rate.

Development of micropump-actuated negative pressure pinched injection for parallel electrophoresis on array microfluidic chip.

2009-09-01

A micropump-actuated negative pressure pinched injection method is developed for parallel electrophoresis on a multi-channel LIF detection system. The system has a home-made device that could individually control 16-port solenoid valves and a high-voltage power supply. The laser beam is excitated and distributes to the array separation channels for detection. The hybrid Glass-PDMS microfluidic chip comprises two common reservoirs, four separation channels coupled to their respective pneumatic micropumps and two reference channels. Due to use of pressure as a driving force, the proposed method has no sample bias effect for separation. There is only one high-voltage supply needed for separation without relying on the number of channels, which is significant for high-throughput analysis, and the time for sample loading is shortened to 1 s. In addition, the integrated micropumps can provide the versatile interface for coupling with other function units to satisfy the complicated demands. The performance is verified by separation of DNA marker and Hepatitis B virus DNA samples. And this method is also expected to show the potential throughput for the DNA analysis in the field of disease diagnosis.

The analysis of the surface of teeth is an important field of research and technological development due to the importance of dental pieces in health and aesthetics. The presence of cracks as well as the etching effects on teeth surface, due to different chemical agents, affects not only the appearance of teeth but its integrity. In this work, laser thermography analysis of dental pieces with damage in the form of cracks is presented. The technique consists in the illumination of the surface at the center of the sample, using a 300 mW pulsed solid state laser beam focused with a gradium lens, and monitoring the spatial and temporal distribution of the temperature field. The heating of the sample is monitored using a focal plane array infrared camera, sensitive in the spectral range 7.5-13 μm with a noise equivalent temperature difference of 0.12°C. The data acquisition was performed by the PC firewire port using a PCI-8254R card and a home-made program in Labview 8.0 was used for data acquisition. The images were processed in a home-made linux program to obtain the experimental table values. Our results are compared with position and frequency scans obtained by infrared photothermal radiometry. It is shown that the crack in the tooth appears as an increase in the photothermal signal. In contrast, the thermographic image shows a more detailed structure in which close to the crack the temperature increases, but at the crack the signal falls.

Environmental exposure to lead and children's intelligence at the age of seven years. The Port Pirie Cohort Study

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

Baghurst, P.A.; McMichael, A.J.; Wigg, N.R.

1992-10-29

Exposure to lead in early childhood is thought to result in delayed neuropsychological development. As yet there is little longitudinal evidence to establish whether these effects persist into later childhood. The authors measured IQ scores in 494 seven-year-old children from the lead-smelting community of Port Pirie, Australia, in whom developmental deficits associated with elevated blood lead concentrations had already been reported at the ages of two and four years. Exposure to lead was estimated from the lead concentrations in maternal blood samples drawn antenatally and at delivery and from blood samples drawn from the children at birth (umbilical-cord blood), atmore » the ages of 6 and 15 months and 2 years, and annually thereafter. Data relating to known covariates of child development were collected systematically for each child throughout the first seven years of life. The authors found inverse relations between IQ at the age of seven years and both antenatal and postnatal blood lead concentrations. After adjustment by multiple regression for sex, parents' level of education, maternal age at delivery, parents' smoking status, socioeconomic status, quality of the home environment, maternal IQ, birth weight, birth order, feeding method (breast, bottle, or both), duration of breast-feeding, and whether the child's natural parents were living together, the relation with lead exposure was still evident for postnatal blood samples, particularly within the age range of 15 months to 4 years. For an increase in blood lead concentration from 10 micrograms per deciliter (0.48 mumol per liter) to 30 micrograms per deciliter (1.45 mumol per liter), expressed as the average of the concentrations at 15 months and 2, 3, and 4 years, the estimated reduction in the IQ of the children was in the range of 4.4 points (95 percent confidence interval, 2.2 to 6.6) to 5.3 points (95 percent confidence interval, 2.8 to 7.8).« less

Development of a New Technique for the Efficient Delivery of Aerosolized Medications to Infants on Mechanical Ventilation

Longest, P. Worth; Tian, Geng

2014-01-01

Purpose To evaluate the efficiency of a new technique for delivering aerosols to intubated infants that employs a new Y-connector, access port administration of a dry powder, and excipient enhanced growth (EEG) formulation particles that change size in the airways. Methods A previously developed CFD model combined with algebraic correlations were used to predict delivery system and lung deposition of typical nebulized droplets (MMAD = 4.9 μm) and EEG dry powder aerosols. The delivery system consisted of a Y-connector [commercial (CM); streamlined (SL); or streamlined with access port (SL-port)] attached to a 4-mm diameter endotracheal tube leading to the airways of a 6-month-old infant. Results Compared to the CM device and nebulized aerosol, the EEG approach with an initial 0.9 μm aerosol combined with the SL and SL-port geometries reduced device depositional losses by factors of 3-fold and >10-fold, respectively. With EEG powder aerosols, the SL geometry provided the maximum tracheobronchial deposition fraction (55.7%), whereas the SL-port geometry provided the maximum alveolar (67.6%) and total lung (95.7%) deposition fractions, respectively. Conclusions Provided the aerosol can be administered in the first portion of the inspiration cycle, the proposed new method can significantly improve the deposition of pharmaceutical aerosols in the lungs of intubated infants.

1998-01-01

Over the past decade, high performance computing has evolved rapidly; systems based on commodity microprocessors have been introduced in quick succession from at least seven vendors/families. Porting codes to every new architecture is a difficult problem; in particular, here at NASA, there are many large CFD applications that are very costly to port to new machines by hand. The LCM ("Legacy Code Modernization") Project is the development of an integrated parallelization environment (IPE) which performs the automated mapping of legacy CFD (Fortran) applications to state-of-the-art high performance computers. While most projects to port codes focus on the parallelization of the code, we consider porting to be an iterative process consisting of several steps: 1) code cleanup, 2) serial optimization,3) parallelization, 4) performance monitoring and visualization, 5) intelligent tools for automated tuning using performance prediction and 6) machine specific optimization. The approach for building this parallelization environment is to build the components for each of the steps simultaneously and then integrate them together. The demonstration will exhibit our latest research in building this environment: 1. Parallelizing tools and compiler evaluation. 2. Code cleanup and serial optimization using automated scripts 3. Development of a code generator for performance prediction 4. Automated partitioning 5. Automated insertion of directives. These demonstrations will exhibit the effectiveness of an automated approach for all the steps involved with porting and tuning a legacy code application for a new architecture.

A wasted world

It is still legal under American law to dump waste products in any country whose government consents to accept them. Many developing countries accept waste exports for a per ton charge. It does not matter to them whether the waste is hazardous, toxic, nonhazardous, or nontoxic. Nor does it matter to them whether or not they have the technology for the safe disposal of wastes. In some nations there is little or no thought about the long-term consequences of unsafe disposal of hazardous wastes to their land, air, water, quality of life, crops, animals and children. Some of the mainmore » culprits in the U.S. have been surprising: the Pentagon, other federal agencies, state and local governments, the American business community in general, and, of course, various brokers and entrepreneurs have all been documented, time and again, as exporters of hazardous waste to the Third World. And then there are the illegal waste shipments, perpetrated by hustlers and nice people alike in many industrialized nations. Here is a sample: In September 1987, Italian ships unloaded 10,000 steel drums of hazardous waste in the Nigerian port of Koko and stored them in a vacant residential lot. The press learned of it in June 1988. The Nigerian government ultimately imprisoned 54 people, including Italian nationals, and formally expressed outrage to the Italian government. The Italian government responded by sending a team of experts to arrange removal. A West German ship was loaded with the waste and went back to Ravenna, Italy, but Italian protestors prevented the ship form docking. It attempted to dock in Spain, France, the Netherlands and the United Kingdom, without success. Finally, a home for the waste was found in an unidentified Italian port in mid-September.« less

2016-08-01

Sea ports are important nodes in the supply chain, joining two high capacity transport modes: rail and maritime transport. The huge cargo flows transiting port requires high capacity construction and installation such as berths, large capacity cranes, respectively shunting yards. However, the port shunting yards specificity raises several problems such as: limited access since these are terminus stations for rail network, the in-output of large transit flows of cargo relatively to the scarcity of the departure/arrival of a ship, as well as limited land availability for implementing solutions to serve these flows. It is necessary to identify technological solutions that lead to an answer to these problems. The paper proposed a simulation model developed with ARENA computer simulation software suitable for shunting yards which serve sea ports with access to the rail network. Are investigates the principal aspects of shunting yards and adequate measures to increase their transit capacity. The operation capacity for shunting yards sub-system is assessed taking in consideration the required operating standards and the measure of performance (e.g. waiting time for freight wagons, number of railway line in station, storage area, etc.) of the railway station are computed. The conclusion and results, drawn from simulation, help transports and logistics specialists to test the proposals for improving the port management.

Practical solutions for reducing container ships' waiting times at ports using simulation model

NASA Astrophysics Data System (ADS)

Sheikholeslami, Abdorreza; Ilati, Gholamreza; Yeganeh, Yones Eftekhari

2013-12-01

The main challenge for container ports is the planning required for berthing container ships while docked in port. Growth of containerization is creating problems for ports and container terminals as they reach their capacity limits of various resources which increasingly leads to traffic and port congestion. Good planning and management of container terminal operations reduces waiting time for liner ships. Reducing the waiting time improves the terminal's productivity and decreases the port difficulties. Two important keys to reducing waiting time with berth allocation are determining suitable access channel depths and increasing the number of berths which in this paper are studied and analyzed as practical solutions. Simulation based analysis is the only way to understand how various resources interact with each other and how they are affected in the berthing time of ships. We used the Enterprise Dynamics software to produce simulation models due to the complexity and nature of the problems. We further present case study for berth allocation simulation of the biggest container terminal in Iran and the optimum access channel depth and the number of berths are obtained from simulation results. The results show a significant reduction in the waiting time for container ships and can be useful for major functions in operations and development of container ship terminals.

Strong Motion Instrumentation of Seismically-Strengthened Port Structures in California by CSMIP

USGS Publications Warehouse

Huang, M.J.; Shakal, A.F.

2009-01-01

The California Strong Motion Instrumentation Program (CSMIP) has instrumented five port structures. Instrumentation of two more port structures is underway and another one is in planning. Two of the port structures have been seismically strengthened. The primary goals of the strong motion instrumentation are to obtain strong earthquake shaking data for verifying seismic analysis procedures and strengthening schemes, and for post-earthquake evaluations of port structures. The wharves instrumented by CSMIP were recommended by the Strong Motion Instrumentation Advisory Committee, a committee of the California Seismic Safety Commission. Extensive instrumentation of a wharf is difficult and would be impossible without the cooperation of the owners and the involvement of the design engineers. The instrumentation plan for a wharf is developed through study of the retrofit plans of the wharf, and the strong-motion sensors are installed at locations where specific instrumentation objectives can be achieved and access is possible. Some sensor locations have to be planned during design; otherwise they are not possible to install after construction.

The author has identified the following significant results. Seven major counties were examined: Escambia, Bay, Gulf, Franklin, Wakulla, Nassau, and Duval. Population and economic activity were reviewed, along with commercial fishing and port facilities. Recommendations for five northwest Florida counties were based on interpretation of aerial photographs, satellite imagery, an aerial survey site visit, and published data. Major needs in Pensacola included docking, ice supply, and net and engine repair services. Costs for additional docks, an ice plant, and gear storage were estimated at $3,658,600. Port users in Panama City identified additional docking and gear storage as primary needs, along with gear repair and a marine railway. Estimated costs for dock and gear storage were $2,860,000. Added docking, gear storage, and ice supply, as well as gear electronics and diesel repair were needed in Port St. Joe. Costs were calculated at $1,231,500. Franklin County has three ports (Apalachicola - $1,107,000 for docks and gear storage, Eastpoint - $420,000 for additional docks, and Carrabella - $2,824,100 for docks, gear storage, and ice plant).

According to Presidential Regulation Number 26 year of 2012 about the National Logistics System Development Blueprint, the Indonesian government proposed to build two international hub ports, which were in Port of Kuala Tanjung for the western region and Port of Bitung for eastern region. Therefore, the optimum routes and fleet size are required to support the enforcement of Indonesian International Hub Port. The optimization model is used to obtain the optimum route and fleet by minimizing the total shipping costs, while considering the container demand. The result of analysis obtained that the optimum route and fleet size for the western region of Indonesia were: (1) Kuala Tanjung-Belawan required 15 ships of 1,000 TEU; (2) Kuala Tanjung-Tanjung Priok required 73 ships of 2,500 TEU; (3) Kuala Tanjung- Tanjung Perak required 44 ships of 2,500 TEU. Meanwhile, the optimum route and fleet size for the eastern region of Indonesia consisted of: (1) Bitung-Sorong required 1 ship of 500 TEU; (2) Bitung-Banjarmasin required 3 ships of 500 TEU; and (3) Bitung-Makassar required 1 ship of 1,500 TEU.

Centralized equipment controls in an operating room (OR) is crucial to an efficient workflow in the OR. To achieve centralized control, an integrative OR needs to focus on designing a control panel that can appropriately incorporate equipment from different manufactures with various connecting ports and controls. Here we propose to achieve equipment integration using plug-in modules. Each OR will be equipped with a dynamic plug-in control panel containing physically removable connecting ports. Matching outlets will be installed onto the control panels of each equipment used at any given time. This dynamic control panel will be backed with a database containing plug-in modules that can connect any two types of connecting ports common among medical equipment manufacturers. The correct connecting ports will be called using reflection dynamics. This database will be updated regularly to include new connecting ports on the market, making it easy to maintain, update, expand and remain relevant as new equipment are developed. Together, the physical panel and the database will achieve centralized equipment controls in the OR that can be easily adapted to any equipment in the OR.

The aim of this study was to determine the knowledge levels of Turkish nurses regarding implantable port catheter care. A descriptive method was used inside a university hospital that was located in a Turkish metropolis. The data were collected via a questionnaire that was given to a total of 45 nurses who were employed in the internal medicine clinics where the oncology patients were treated. In this study, 42.2% of the nurses received in-service training about the implantable port catheter. It was determined that the mean knowledge point was 15.13 ± 4.78. The difference between the knowledge points of the nurses regarding implantable port catheter care, based on whether or not the nurses had received in-service training, was statistically significant. Moreover, it was determined that the majority of the nurses did not know where the implantable port catheter is placed, its period of use following implantation, the amount of normal saline to be used for washing the catheter, the special port (Huber) needle, the number of the needle, and the exchange time of these needles. In this study, there existed significant differences between the scores of the nurses who received in-service training about the implantable port catheter and the scores of those who did not receive in-service training. The majority of the nurses who participated in the study were willing to receive in-service training regarding this subject. Thus, the organization of in-service training programs and the implementation of care, according to the developed standards and guidelines, are considered as significant for reducing the occurrence of the complications that are related to the use of the implantable port catheter. © 2011 The Authors.

Background The development of single-port thoracoscopic surgery and two-lung ventilation reduced the invasiveness of minor thoracic surgery. This study aimed to evaluate the feasibility and safety of single-port thoracoscopic bleb resection for primary spontaneous pneumothorax using two-lung ventilation with carbon dioxide insufflation. Methods Between February 2009 and May 2014, 130 patients underwent single-port thoracoscopic bleb resection under two-lung ventilation with carbon dioxide insufflation. Access was gained using a commercial multiple-access single port through a 2.5-cm incision; carbon dioxide gas was insufflated through a port channel. A 5-mm thoracoscope, articulating endoscopic devices, and flexible endoscopic staplers were introduced through a multiple-access single port for bulla resection. Results The mean time from endotracheal intubation to incision was 29.2±7.8 minutes, the mean operative time was 30.9±8.2 minutes, and the mean total anesthetic time was 75.5±14.4 minutes. There were no anesthesia-related complications or wound problems. The chest drain was removed after a mean of 3.7±1.4 days and patients were discharged without complications 4.8±1.5 days from the operative day. During a mean 7.5±10.1 months of follow-up, there were five recurrences (3.8%) in operated thorax. Conclusions The anesthetic strategy of single-lumen intubation with carbon dioxide gas insufflation can be a safe and feasible option for single-port thoracoscopic bulla resection as it represents the least invasive surgical option with the potential advantages of reducing operative time and one-lung ventilation-related complications without diminishing surgical outcomes.

Cost-benefit management trends in Taiwan healthcare settings have led nurses to perform more invasive skills, such as Port-A cath administration of medications. Accordingly, nurses must be well-prepared prior to teaching by the mentor and supervision method. The purpose of the current study was to develop a computer-assisted protocol using virtual reality (VR) in performing Port-A cath as a training program for novice nurses. A pre-tested and post-tested control group experimental design was used in this study. Seventy-seven novice nurses were invited from one large medical center hospital in North Taiwan. Thirty-seven and forty nurses were randomly assigned to experimental and control groups. First, we designed a 40 minute port-A cath injection VR simulation. Then, the experimental group practiced this simulation two times over 3 weeks. The control group attended the traditional class. The post-test 1 was right after completion of the simulation practice. The post-test 2 was after the second simulation practice in 3 weeks. The results showed that most novice nurses lacked Port-A cath experience both in the classroom and during the period of their practice training. The knowledge score regarding the Port-A cath technique was significantly higher in the nurses that participated in the simulation training than in the control group. The novice nurses were most satisfied with the reduction in their fear of performing the Port-A cath technique and their enhanced clinical skills. VR simulation significantly reduced error rates and increased correct equipment selection, showing that nurses who participated in the simulation may be better prepared for inserting Port-A cath.

Video-assisted thoracoscopic surgery has become the technique of choice in the early stages of lung cancer in many centers although there is no evidence that all of the surgical approaches achieve the same long-term survival. We carried out a retrospective review of 276 VATS lobectomies performed in our department, analyzing age, sex, comorbidities, current smoker, FEV1 and FCV, surgical approach, TNM and pathological stage, histologic type, neoadjuvant or coadjuvant chemotherapy, relapse and metastasis time, with the main aim of evaluating the survival rate and disease-free time, especially with regard to the two/three versus single port approach. The one/four year global survival rate was 88.1 and 67.6% respectively. Bivariate analysis found that the variables associated with survival are comorbidity, histological type, stage, surgical approach and need for chemotherapy. When we independently analyzed the surgical approach, we found a lower survival rate in the single-port group vs. the two/three-port group (VATS). Stratifying by tumoral stage (stage I) and by tumor size (T2) survival was significantly lower for patients with single-port group in comparison to VATS approach. In the multivariate analysis, single-port group is associated with a higher risk of death (HR=1.78). In analyzing disease-free survival, differences were found in both cases in favor of two/three port VATS: p=.093 for local relapses and p=.091 for the development of metastasis. These results challenge the use of the single port technique in malignant lung pathologies, suggesting the need for clinical trials in order to identify the role this technique may have in lung cancer surgery.

Faulkner, Katelyn T.

2017-01-01

The global shipping network facilitates the transportation and introduction of marine and terrestrial organisms to regions where they are not native, and some of these organisms become invasive. South Africa was used as a case study to evaluate the potential for shipping to contribute to the introduction and establishment of marine and terrestrial alien species (i.e. establishment debt) and to assess how this varies across shipping routes and seasons. As a proxy for the number of species introduced (i.e. ‘colonisation pressure’) shipping movement data were used to determine, for each season, the number of ships that visited South African ports from foreign ports and the number of days travelled between ports. Seasonal marine and terrestrial environmental similarity between South African and foreign ports was then used to estimate the likelihood that introduced species would establish. These data were used to determine the seasonal relative contribution of shipping routes to South Africa’s marine and terrestrial establishment debt. Additionally, distribution data were used to identify marine and terrestrial species that are known to be invasive elsewhere and which might be introduced to each South African port through shipping routes that have a high relative contribution to establishment debt. Shipping routes from Asian ports, especially Singapore, have a particularly high relative contribution to South Africa’s establishment debt, while among South African ports, Durban has the highest risk of being invaded. There was seasonal variation in the shipping routes that have a high relative contribution to the establishment debt of the South African ports. The presented method provides a simple way to prioritise surveillance effort and our results indicate that, for South Africa, port-specific prevention strategies should be developed, a large portion of the available resources should be allocated to Durban, and seasonal variations and their consequences for prevention strategies should be explored further.

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

Single-port video-assisted thoracoscopic lobectomy is still difficult for most thoracic surgeons. Placement of an endo-stapler is one of the key issues when handling the bronchus or pulmonary vessels through one incision, especially if it would interfere with the traction belt. Therefore, we developed a novel method with an intrathoracic vertical overhanging approach to make the placement of the endo-stapler easier during single-port video-assisted thoracoscopic surgery lobectomy, and share our experience in this paper. © The Author 2015.

A two-stroke poppet valve engine is developed to overcome the common problems in conventional two-stroke engine designs. However, replacing piston control port with poppet valve will resulted different flow behaviour. This paper is looking at experimental assessment on a two-stroke poppet valve engine configuration to investigate the port flow performance. The aims are to evaluate the intake and exhaust coefficient of discharge and assess the twostroke capability of the cylinder head. The results has shown comparable coefficient of discharge values as production engine for the intake while the exhaust has higher values which is favourable for the two-stroke cycle operation.

Single-incision laparoscopic cholecystectomy for biliary dyskinesia in children: a simple, safe, and inexpensive technique.

Leinwand, Michael J; Elgamal, Mohamed H

2013-04-01

To evaluate a low-cost technique for single-incision laparoscopic cholecystectomy (SILC) in children with biliary dyskinesia. Eighteen children with biliary dyskinesia underwent SILC between March and September 2010. Two 5-mm trocars and a directly introduced grasper were inserted through a 2-cm vertical transumbilical incision. Instrument collisions were minimized by using low-profile trocars and a bariatric laparoscope with a right-angle light adaptor. An internally anchored retracting device suspended the gallbladder, obviating the need for an additional trocar. No other special equipment was used. There were 15 girls and 3 boys with a mean age of 15.9 years (range, 9-18 years). Sixteen (88.9%) underwent true SILC. One patient was converted to a four-port laparoscopic procedure because of uncertainty of ductal anatomy. Another required a 5-mm subxiphoid port for liver retraction. Mean operative time was 82 minutes (range, 42-105 minutes): 94 minutes (range, 75-105 minutes) for the first 6 patients, 85 minutes (range, 60-102 minutes) for the second 6, and 68 minutes (range, 42-90 minutes) for the last 6. Operative times between the first and last groups were significantly different (P=.02). Sixteen patients were discharged home the following day and the remaining 2 on the second postoperative day. There were no complications. The hospital costs of the disposable equipment needed to perform SILC at our institution was $205.05 less than that needed for the four-port operation ($516.32 versus $721.37), a 28.4% savings. SILC is safe and feasible in children with biliary dyskinesia. The operative time decreased with experience. The disposable equipment needed was less expensive than that used for the standard laparoscopic technique.

Single-incision laparoscopic surgery (SILS) has been demonstrated to be a feasible alternative to multiport laparoscopy, but concerns over port-site incisional hernias have not been well addressed. A retrospective study was performed to determine the rate of port-site hernias as well as influencing risk factors for developing this complication. A review of all consecutive patients who underwent SILS over 4 years was conducted using electronic medical records in a multi-specialty integrated healthcare system. Statistical evaluation included descriptive analysis of demographics in addition to bivariate and multivariate analyses of potential risk factors, which were age, gender, BMI, procedure, existing insertion-site hernia, wound infection, tobacco use, steroid use, and diabetes. 787 patients who underwent SILS without conversion to open were reviewed. There were 454 cholecystectomies, 189 appendectomies, 72 colectomies, 21 fundoplications, 15 transabdominal inguinal herniorrhaphies, and 36 other surgeries. Cases included 532 (67.6 %) women, and among all patients mean age was 44.65 (±19.05) years and mean BMI of 28.04 (±6). Of these, 50 (6.35 %) patients were documented as developing port-site incisional hernias by a health care provider or by incidental imaging. Of the risk factors analyzed, insertion-site hernia, age, and BMI were significant. Multivariate analysis indicated that both preexisting hernia and BMI were significant risk factors (p value = 0.00212; p value = 0.0307). Morbidly obese patients had the highest incidence of incisional hernias at 18.18 % (p value = 0.02). When selecting patients for SILS, surgeons should consider the presence of an umbilical hernia, increased age and obesity as risk factors for developing a port-site hernia.

Physical Oceanographic Real-Time System (PORTS) (Invited)

NASA Astrophysics Data System (ADS)

Wright, D.

2013-12-01

The 1999 Assessment of U.S. Marine Transportation System report to Congress noted that the greatest safety concern voiced by the maritime community was the availability of timely, accurate, and reliable navigation information, including real time environment data. Real time oceanographic and meteorological data, along with other navigation tools, gives the mariner a good situational understanding of their often challenging operational environment, to make the best safety of life and property decisions. The National Oceanic and Atmospheric Administration's (NOAA) Physical Oceanographic Real Time System (PORTS) was developed in response to accidents like the Sunshine Skyway Bridge collision in Tampa, FL in 1980, where the lack of accurate, reliable and timely environmental conditions directly contributed to an accident that resulted in a high loss of life and property. Since that time, PORTS has expanded to over 20 locations around the country, and its capabilities have been continually expanded and improved as well. PORTS primary mission is to prevent maritime accidents. Preventing an accident from occurring is the most cost effective approach and the best way to avoid damage to the environment. When accidents do occur, PORTS data is used to improve the effectiveness of response efforts by providing input for trajectory models and real time conditions for response efforts. However, benefits derived from PORTS go well beyond navigation safety. Another large benefit to the local maritime community is potential efficiencies in optimizing use of the existing water column. PORTS provides information that can be used to make economic decisions to add or offload cargo to a vessel and/or to maintain or adjust transit schedules based upon availability of water depth, strength/timing of tidal currents, and other conditions. PORTS data also helps improve and validate local National Weather Service marine weather forecasts. There are many benefits beyond the local maritime community. PORTS data often proves critical when hurricanes or other severe weather events impact an area with the data helping inform the local emergency response infrastructure. PORTS data can also help support local habitat restoration efforts through improved tidal datums, frequency of inundation projections, and sea level trends.

Ka-Band TWT High-Efficiency Power Combiner for High-Rate Data Transmission

NASA Technical Reports Server (NTRS)

Wintucky, Edwin G.; Simons, Rainee; Vaden, Karl R.; Lesny, Gary G.; Glass, Jeffrey L.

2007-01-01

A four-port magic-T hybrid waveguide junction serves as the central component of a high-efficiency two-way power combiner circuit for transmitting a high-rate phase-modulated digital signal at a carrier frequency in the Ka-band (between 27 and 40 GHz). This power combiner was developed to satisfy a specific requirement to efficiently combine the coherent outputs of two traveling-wavetube (TWT) amplifiers that are typically characterized by power levels on the order of 100 W or more. In this application, the use of a waveguide-based power combiner (instead of a coaxial-cable- or microstrip-based power combiner, for example) is dictated by requirements for low loss, high power-handling capability, and broadband response. Combiner efficiencies were typically 90 percent or more over both the linear and saturated output power regions of operation of the TWTs . Figure 1 depicts the basic configuration of the magic-T hybrid junction. The coherent outputs of the two TWTs enter through ports 1 and 4. As a result of the orientations of the electromagnetic fields, which also provides a needed high port-to-port isolation, of these two input signals and the interior design of the magic-T junction, the input powers are divided so as to add in phase at one output port (port 2), and to be opposite in phase and hence cancel each other at the opposite coplanar output port (port 3). The net result is that the output power at port 2 is essentially double that of the output of one TWT, minus the power lost in the magic-T hybrid junction. Optimum performance as a high-efficiency power combiner thus requires a balance of both power and phase at the input ports of the magic-T. Replicas of this two-way combiner can be arranged in a binary configuration to obtain a 2n-way (where n is an integer) combiner. For example, Figure 2 illustrates the use of three two-way combiners to combine the outputs of four TWTs.

The unique device architecture of the Cleveland Clinic continuous-flow total artificial heart (CFTAH) requires dedicated and specific air-removal techniques during device implantation in vivo. These procedures comprise special surgical techniques and intraoperative manipulations, as well as engineering design changes and optimizations to the device itself. The current study evaluated the optimal air-removal techniques during the Cleveland Clinic double-ended centrifugal CFTAH in vivo implants (n = 17). Techniques and pump design iterations consisted of developing a priming method for the device and the use of built-in deairing ports in the early cases (n = 5). In the remaining cases (n = 12), deairing ports were not used. Dedicated air-removal ports were not considered an essential design requirement, and such ports may represent an additional risk for pump thrombosis. Careful passive deairing was found to be an effective measure with a centrifugal pump of this design. In this report, the techniques and design changes that were made during this CFTAH development program to enable effective residual air removal and prevention of air embolism during in vivo device implantation are explained. © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

Evaluation of the sensitisation and levels of exposure to grains and its pulmonary impact ina population of Brest port silo employees. We included exposed workers. The study consisted of clinical examination witha standardised questionnaire, blood samples, prick-tests, and spirometry tests. The atmospheric concentrationof total dust in the workplace was also associated. Eight workers were included in the study. No case of occupational asthma was found, but 3 casesof occupational rhinitis were noted and occupational prick-tests were positive in 4 cases. The mean totaldust concentration in the three atmospheric samples was 4.87 mg/m3 for 8 hours but it was under thedetection limits for alveolar fractions. Port silo workers are exposed to total dust concentrations below the French legal limit (10 mg/m3) but higher than Canadian and American recommendations. Levels of exposure in our studyare similar to other studies developed in port silos. Symptoms developed by workers may be due to highexposure to dust with an irritant effect rather than an allergic effect. Despite this fact, a specific medicalsurvey is needed, and ventilation and respiratory masks have to be promoted for prevention.

A family of backside illuminated CCD imagers with 6.6 micrometers pixels has been developed. The imagers feature full 12 bit (> 4,000:1) dynamic range with measured noise floor of < 10 e RMS at 5 MHz clock rates, and measured full well capacity of > 50,000 e. The modulation transfer function performance is excellent, with measured MTF at Nyquist of 46% for 500 nm illumination. Three device types have been developed. The first device is a 1 K X 1 K full frame device with a single output port, which can be run as a 1 K X 512 frame transfer device. The second device is a 512 X 512 frame transfer device with a single output port. The third device is a 512 X 512 split frame transfer device with four output ports. All feature the high quantum efficiency afforded by backside illumination.

Integration of Land and Sea in a Port Area: A Case Study of the Port of Koper

The spatial plan for a port based on land reclamation, existing land, or a combination of both should be designed in line with both reliable data for the existing situation and precise goals based on a well-founded vision by the port authority. In ports, human activities are concentrated in the limited space of the coastal belt, where they threaten the vulnerable equilibrium of the environment. Integrated multifunctional planning of ports is necessary for the sustainability of such plans. In this process, the relation between the environment and the economy is often neglected because the ecosystem—the totality of living organisms—which is fully dependent on biological, chemical, and physical factors, prevails. This method, also called building with nature, is the basis for integrated coastal zone development and management. It emphasizes the flexible integration of land and sea, which respects and uses forces and materials present in nature, and which is an essential interaction between man and environment. Strict ecological planning conditions and the public interest obliged the Port of Koper to modify its urban planning strategies and redefine its relationship with all bordering areas. The extension of two piers and construction of a third one was the result of functional factors, infrastructure connections, technical possibilities, and environmental requirements. Solutions that were relevant for distributing cargo on the docks had to adjust to the width of the basins for manoeuvring ships. Various types of construction restrict water flow under piers, thereby accelerating biomass degradation. Environmental aspects created conditions and requirements for pier construction.

2000-06-01

The Delaware River Port Authority, whose mission is to manage, plan and construct transportation facilities and provide transportation services to maximize the safe and efficient movement of people and freight within the Delaware River Valley, located in southwestern Pennsylvania and southern New Jersey, is a self-financing, bi-state Authority, formed by a compact between the Commonwealth of Pennsylvania and the State of New Jersey and approved by the Congress of the United States. The Delaware River Port Authority is firmly committed to the strategic and integrated use of advanced transportation technology to improve traffic flow, operational efficiency and safety on DRPA's four bridges. To this end, the Delaware River Port Authority has initiated a program, appropriately named 'Smart Bridges.' The Delaware River Port Authority has recognized that this type of program is essential to the advancement of the DRPA's mission as an efficient, customer- friendly transportation and regional development agency. Under the Smart Bridges program the Delaware River Port Authority is introducing new technology into its aging infrastructure and transportation systems to ensure that the facilities continue to serve the region into the 21st century and beyond. Initiatives introduced under this program include EZ Pass, video surveillance systems, computerized traffic control systems and partnering with local universities to investigate the application of various innovative technologies to assist in the maintenance of the bridge facilities.

Needleless connectors may develop bacterial contamination and cause central-line-associated bloodstream infections (CLABSI) despite rigorous application of best-practice. Ultraviolet (UV) light-emitting diodes (LED) are an emerging, increasingly affordable disinfection technology. We tested the hypothesis that a low-power UV LED could reliably eliminate bacteria on needleless central-line ports in a laboratory model of central-line contamination. Needleless central-line connectors were inoculated with Staphylococcus aureus. A 285 nm UV LED was used in calibrated fashion to expose contaminated connectors. Ports were directly applied to agar plates and flushed with sterile saline, allowing assessment of bacterial survival on the port surface and in simulated usage flow-through fluid. UV applied to needleless central-line connectors was highly lethal at 0·5 cm distance at all tested exposure times. At distances >1·5 cm both simulated flow-through and port surface cultures demonstrated significant bacterial growth following UV exposure. Logarithmic-phase S. aureus subcultures were highly susceptible to UV induction/maintenance dosing. Low-power UV LED doses at fixed time and distance from needleless central-line connector ports reduced cultivable S. aureus from >10(6) CFU to below detectable levels in this laboratory simulation of central-line port contamination. Low-power UV LEDs may represent a feasible alternative to current best-practice in connector decontamination. © 2015 The Society for Applied Microbiology.

Kim, J. B.; Won, E.

2018-03-01

Pipelined algorithms implemented in field programmable gate arrays are extensively used for hardware triggers in the modern experimental high energy physics field and the complexity of such algorithms increases rapidly. For development of such hardware triggers, algorithms are developed in C++, ported to hardware description language for synthesizing firmware, and then ported back to C++ for simulating the firmware response down to the single bit level. We present a C++ software framework which automatically simulates and generates hardware description language code for pipelined arithmetic algorithms.

2007-01-01

Background Heavy alcohol consumption rates are higher in the young adult military enlisted population than among civilians of the same age. The literature on alcohol availability, both generally and specifically with respect to work-related drinking, establishes clear links between ease of access, alcohol consumption rates and alcohol-related problems. Methods In this paper, a qualitative analysis of 50 semi-structured interviews with U.S. Navy personnel was combined with quantitative findings from a mail survey of 713 young enlisted men and women in order to shed light on alcohol availability and its correlates in the home port environments of young adult enlisted personnel. The interviews were analyzed by two anthropologists seeking recurring themes or topics related to alcohol availability. These qualitative data were contextualized by descriptive statistics of the survey responses regarding ease of obtaining alcohol on and around naval bases, and from friends in and out of the Navy. Results Findings associated with social and physical availability of alcohol include low prices in Navy Exchange base stores, frequent barracks parties, drink promotions in bars surrounding bases, and multiple opportunities for underage drinking despite age limits on alcohol purchases and official efforts to deglamorize alcohol use in the Navy. Both qualitative and qualitative findings suggest that respondents found alcohol and opportunities to drink overwhelmingly available in both on-base and off-base settings, and from friends both in and out of the Navy. Conclusion There is qualitative and quantitative evidence for extensive physical and social availability of alcohol in and around bases for young adults in the military. Policy implications include raising the presently tax-free alcohol prices in base stores and enforcing existing policies regarding underage drinking, particularly the provision of alcohol by people of legal drinking age, and by bars in and around bases. Cooperative preventive efforts with surrounding communities also offer promising ways for bases to reduce alcohol availability for young adult servicemembers. PMID:17603908

PurposeTo compare incidence of port inversion among different types of implantable venous access devices.Materials and Methods Records of patients who underwent imaging-guided subcutaneous port placement without port fixation between July 2001 and April 2015 were reviewed with use of a quality assurance database. 1930 patients with complete follow-up (death or explant) were included in the study. Collected data included date and indication for port placement, port type, venous access site, immediate and long-term complications, indication for removal, and total number of catheter days. BMI of patients with inverted ports was also calculated.Results Port inversion within the pocket was observed inmore » 18 patients (0.9%) including 7/82 (9%) of Dignity ports, 4/126 (3%) of Vaxcel plastic arm ports, 3/142 (2%) of Smartports, 2/100 (2%) of Powerports, 1/14 (7%) of Vaccess ports, and 1/1421 (0.07%) of Vortex LP ports. Among these designs, the inversion rate was significantly lower in Vortex LP ports (0.1%) (P < 0.05). There was a trend toward higher inversion rate of Dignity ports, which have a rectangular design with a relatively narrow base. Mean dwell in inverted ports was 114 days (7–580).Conclusion The incidence of port inversion without suture fixation of the port base to the pocket is extremely low. The present study shows differences in inversion incidence based on port design.Level of Evidence: Case Series, Level IV.« less

Totally implantable venous access devices (ports) are widely used, especially for cancer chemotherapy. Although their use has been associated with upper extremity deep venous thrombosis, the risk factors of upper extremity deep venous thrombosis in patients with a port are not studied adequately. The Healthcare Cost and Utilization Project's Florida State Ambulatory Surgery and Services Database was queried between 2007 and 2011 for patients who underwent outpatient port insertion, identified by Current Procedural Terminology code. Patients were followed in the State Ambulatory Surgery and Services Database, State Inpatient Database, and State Emergency Department Database for upper extremity deep venous thrombosis occurrence. The cohort was divided into a test cohort and a validation cohort based on the year of port placement. A multivariable logistic regression model was developed to identify risk factors for upper extremity deep venous thrombosis in patients with a port. The model then was tested on the validation cohort. Of the 51,049 patients in the derivation cohort, 926 (1.81%) developed an upper extremity deep venous thrombosis. On multivariate analysis, independently significant predictors of upper extremity deep venous thrombosis included age <65 years (odds ratio = 1.22), Elixhauser score of 1 to 2 compared with zero (odds ratio = 1.17), end-stage renal disease (versus no kidney disease; odds ratio = 2.63), history of any deep venous thrombosis (odds ratio = 1.77), all-cause 30-day revisit (odds ratio = 2.36), African American race (versus white; odds ratio = 1.86), and other nonwhite races (odds ratio = 1.35). Additionally, compared with genitourinary malignancies, patients with gastrointestinal (odds ratio = 1.55), metastatic (odds ratio = 1.76), and lung cancers (odds ratio = 1.68) had greater risks of developing an upper extremity deep venous thrombosis. This study identified major risk factors of upper extremity deep venous thrombosis. Further studies are needed to evaluate the appropriateness of thromboprophylaxis in patients at greater risk of upper extremity deep venous thrombosis. Copyright © 2017 Elsevier Inc.

We present on-line molecular composition measurements of wintertime particulate matter (PM) during 2014 using an iodide-adduct high-resolution, time-of-flight chemical ionization mass spectrometer (HR-TOF-CIMS) coupled to a Filter Inlet for Gases and AEROsols (FIGAERO). These measurements were part of an intensive effort to characterize PM in the region with a focus on ultrafine particle sources. The technique was used to detect and quantify different classes of wood burning tracers, including levoglucosan, methoxyphenols, and nitrocatechols, among other compounds in near real-time. During the campaign, particulate mass concentrations of compounds with the same molecular composition as levoglucosan ranged from 0.002 to 19 μg/m3 with a median mass concentration of 0.9 μg/m3. Wood burning markers, in general, showed a strong diurnal pattern peaking at night and in the early morning. This diurnal profile combined with cold, stagnant conditions, wind directions from predominantly residential areas, and observations of lower combustion efficiency at night support residential wood burning as a dominant source of wintertime PM in Port Angeles. This finding has implications for improving wintertime air quality in the region by encouraging the use of high efficiency wood-burning stoves or other cleaner home heating options throughout the relevant domain.

To observe changes in intraocular pressure (IOP), the manner in which the eye is suctioned, and the effect of the number of suction ports. Department of Ophthalmology, Tokyo Dental College, Suidobashi Hospital, Tokyo, Japan. Suction rings with single or dual ports were made of transparent acrylic acid resin to facilitate observation with a digital video camera. The IOP and the duration of the IOP increase (time to reach 90% of the maximum IOP) were measured in 6 porcine eyes with an intra-vein pressure-sensor catheter in the vitreous cavity. The IOP changes were recorded using a personal computer. Suctioning with single- and dual-port suction rings was similar. The IOP increases with single- and dual-port suction rings were similar (99.1 mm Hg +/- 6.1 [SD] and 99.0 +/- 6.5 mm Hg, respectively) (P=.987). The duration of the IOP increase was also similar (4.21 +/- 0.24 seconds and 4.12 +/- 0.33 seconds, respectively) (P=.190). The number of ports did not affect suctioning and changes in IOP. This technique is useful in developing the ideal shape and setting of the suction ring.

Seaport monitoring and management is a significant research area, in which infrastructure automatically collects big data sets that lead the organization in its multiple activities. Thus, this problem is heavily related to the fields of data acquisition, transfer, storage, big data analysis and information visualization. Las Palmas de Gran Canaria port is a good example of how a seaport generates big data volumes through a network of sensors. They are placed on meteorological stations and maritime buoys, registering environmental parameters. Likewise, the Automatic Identification System (AIS) registers several dynamic parameters about the tracked vessels. However, such an amount of data is useless without a system that enables a meaningful visualization and helps make decisions. In this work, we present SmartPort, a platform that offers a distributed architecture for the collection of the port sensors’ data and a rich Internet application that allows the user to explore the geolocated data. The presented SmartPort tool is a representative, promising and inspiring approach to manage and develop a smart system. It covers a demanding need for big data analysis and visualization utilities for managing complex infrastructures, such as a seaport. PMID:27011192

Radiation shielding analysis conducted in support of design development of the contemporary diagnostic systems integrated inside the ITER ports is relied on the use of CAD models. This paper presents the CAD-based MCNP Monte Carlo radiation transport and activation analyses for the Diagnostic Upper and Equatorial Port Plugs (UPP #3 and EPP #8, #17). The creation process of the complicated 3D MCNP models of the diagnostics systems was substantially accelerated by application of the CAD-to-MCNP converter programs MCAM and McCad. High performance computing resources of the Helios supercomputer allowed to speed-up the MCNP parallel transport calculations with the MPI/OpenMP interface. The found shielding solutions could be universal, reducing ports R&D costs. The shield block behind the Tritium and Deposit Monitor (TDM) optical box was added to study its influence on Shut-Down Dose Rate (SDDR) in Port Interspace (PI) of EPP#17. Influence of neutron streaming along the Lost Alpha Monitor (LAM) on the neutron energy spectra calculated in the Tangential Neutron Spectrometer (TNS) of EPP#8.

Two distinct yet closely related waste remediation projects are finally underway in Canada under the Port Hope Area Initiative (PHAI) which aims to clean up 1.7 million cubic metres (m{sup 3}) of low-level radioactive waste (LLRW) arising from 60 years of uranium and radium operations. Under the PHAI, the Port Hope Project and the smaller Port Granby Project will result in the consolidation of the LLRW within two highly engineered, above-ground mounds, to be constructed within the municipalities of Port Hope and Clarington. These projects will fulfill the federal government commitment to the safe, long-term management of the LLRW, asmore » set out in the legal agreement signed by the government and the host municipalities in 2001. The federal authorization to commence PHAI Remediation and Construction Phase 2 was received in late 2011 and several enabling infrastructure construction and radiological survey contracts were awarded in 2012. The contracts to remediate the waste sites and construct the new engineered mounds will be tendered in 2013. At the end of Phase 2, environmental risks will be substantially mitigated, land development restrictions lifted, and an honourable legacy left for future generations. (authors)« less

A detailed exhaust emission inventory of ships by using Automatic Identification System (AIS) data was developed for Tianjin Port, one of the top 10 world container ports and the largest port in North China. It was found that in 2014, ship emissions are 2.93 × 104, 4.13 × 104, 4.03 × 103, 3.72 × 103, 1.72 × 103 and 3.57 × 103 tonnes of SO2, NOx, PM10, PM2.5, NMVOC and CO respectively, which are equivalent to 11.07%, 9.40%, 2.43%, 3.10%, 0.43% and 0.16% respectively of the non-ship anthropogenic totals in Tianjin. The total CO2 emissions is approximately 1.97 × 106 tonnes. The container ships and dry bulk cargo ships contributed about 70% of the total ship emissions of NOx, SO2 and PM10. Pollutants were mainly emitted during cruise and hotelling modes, and the highest intensities of emissions located in the vicinity of fairways, berth and anchorage areas in Tianjin Port. Distinctive difference between the lowest (February) and the highest (September) monthly emissions is due to the adjustment of freight volume during the Chinese New Year and the months before and after it.

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,more » 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.« less

Though postoperative radiation for esophageal squamous cell carcinoma is offered in selected cases, there is conflicting evidence as to whether it improves overall survival (OS). A retrospective investigation was performed to analyze the prognostic impact of postoperative radiation therapy (PORT) in a large cohort of patients. From 2001 to 2009, 725 patients underwent radical esophagectomy (R0) with or without PORT were eligible for retrospective analysis. Patients were grouped into surgery alone (n = 467) and surgery plus PORT (n = 258). Median irradiation doses were 50 Gy (range: 40-56 Gy). Radiation fields encompassed the bilateral supraclavicular fossa, mediastinum, subcarinal area, and the tumor bed for the upper/middle-third disease; the bilateral supraclavicular fossa, mediastinum, the tumor bed, subcarinal area, and lower thoracic paraesophageal area for the lower-third disease. Kaplan-Meier and Cox regression analysis were used to compare OS. After median follow-up of 53 months, the median OS was 29 months in the PORT group and 23 months in the surgery alone group. The addition of PORT improved OS at 3 years from 36.6 to 43.6% compared with surgery alone. The use of PORT was associated with significantly improved OS (p = 0.018). For American Joint Committee on Cancer (AJCC) stage III esophageal cancer (T1-2N2M0, T3N1-2M0, T4N1-3M0), there was significant improvement in OS (p = 0.002) in the PORT group, not only for lymph-node metastatic ratio (LNMR) ≥0.25 (p = 0.001), but also for LNMR <0.25 (p = 0.043). However, for stage IIB disease (T1-2N1M0) there was no significant differences. The addition of POCT didn't prolong the OS significantly (Surgery alone group, p = 0.079; PORT group, p = 0.111). This large retrospective analysis supports the use of PORT for pathologic lymph node positive stage III esophageal squamous cell carcinoma. Given the retrospective nature of this study, the results should be confirmed by appropriately powered randomized trials. Further development of adjuvant therapy in EC is warranted.

Laparoscopic adrenalectomy is currently the standard of care for adrenal lesion. Minimal invasive laparoscopic surgery such as laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) have been developed to improve cosmetic outcomes and reduce postoperative pain. However, there are still some problems related to instruments and port limitation during LESS surgery. Robot-assisted laparoscopic surgery may help to overcome these problems, and port platforms selection is an important issue. Three cases received robot-assisted LESS adrenalectomy due to adrenal tumor were enrolled. Blood loss, hospital stay, and analgesia injection were compared. Preoperative evaluations were done in a usual manner. Benign tumors were suspect for two patients, while metastatic tumor could not be excluded for the other patient with prior malignancy history. The pathology reports were all benign adrenal cortical adenoma after operation. Three different port platforms, Da Vinci Single-Site Surgical Platform, GelPOINT, and homemade glove port were used. Trans-peritoneal approach was used for two patients, while the other one received trans-retroperitoneal approach. The advantage and disadvantage of different port platforms were discussed. All patients underwent the operation smoothly without major complications or conversion to open surgery. Blood loss amount was small, hospital stay was short, and only one patient received one single dose of opioid analgesia injection after the surgery. The main problems of LESS are the loss of a working triangle and the limitations of the instruments. Robot-assisted LESS may help surgeons overcome part of these problems. Many different port platforms are available, and based on our initial experience, we believe that the GelPoint may be a more suitable platform, for it maintains the endo-wrist function of the Da Vinci instruments, and allows the surgeon to design the position of ports freely to minimize external and internal collision.

Located in the heart of Vancouver Island, BC, Port Alberni has a well-known history of tsunamis. Many of the Nuu-Chah-Nulth First Nations share oral stories about a strong fight between a thunderbird and a whale that caused big waves in a winter night, a story that is compatible with the recently recognized great Cascadia tsunami in January, 1700. Port Alberni, with a total population of approximately 20,000 people, lies beside the Somass River, at the very end of Barkley Sound Inlet. The narrow canal connecting this town to the Pacific Ocean runs for more than 64 km ( 40 miles) between steep mountains, providing an ideal setting for the amplification of tsunami waves through funnelling effects. The devastating effects of tsunamis are still fresh in residents' memories from the impact of the 1964 Alaska tsunami that caused serious damage to the city. In June 2016, Emergency Management BC ran a coastal exercise in Port Alberni, simulating the response to an earthquake and a tsunami. During three days, the emergency teams in the City of Port Alberni practiced and learned from the experience. Ocean Networks Canada contributed to this exercise with the development of preliminary simulations of tsunami impact on the city from a buried rupture of the Cascadia Subduction Zone, including the Explorer segment. Wave propagation was simulated with the long-wave model FUNWAVE-TVD. Preliminary results indicate a strong amplification of tsunami waves in the Port Alberni area. The inundation zone in Port Alberni had a footprint similar to that of the 1700 Cascadia and 1964 Alaska tsunamis, inundating the area surrounding the Somass river and preferentially following the Kitsuksis and Roger Creek river margins into the city. Several other tsunami source scenarios, including splay faulting and trench-breaching ruptures are currently being modeled for the city of Port Alberni following a similar approach. These results will be presented at the conference.

The California Tsunami Program coordinated by CalOES and CGS in cooperation with NOAA and FEMA has begun implementing a plan to increase awareness of tsunami generated hazards to the maritime community (both ships and harbor infrastructure) through the development of in-harbor hazard maps, offshore safety zones for boater evacuation, and associated guidance for harbors and marinas before, during and following tsunamis. The hope is that the maritime guidance and associated education and outreach program will help save lives and reduce exposure of damage to boats and harbor infrastructure. An important step in this process is to understand the causative mechanism for damage in ports and harbors, and then ensure that the models used to generate hazard maps are able to accurately simulate these processes. Findings will be used to develop maps, guidance documents, and consistent policy recommendations for emergency managers and port authorities and provide information critical to real-time decisions required when responding to tsunami alert notifications. The goals of the study are to (1) evaluate the effectiveness and sensitivity of existing numerical models for assessing maritime tsunami hazards, (2) find a relationship between current speeds and expected damage levels, (3) evaluate California ports and harbors in terms of tsunami induced hazards by identifying regions that are prone to higher current speeds and damage and to identify regions of relatively lower impact that may be used for evacuation of maritime assets, and (4) determine ';safe depths' for evacuation of vessels from ports and harbors during a tsunami event. This presentation will focus on the results from five California ports and harbors, and will include feedback we have received from initial discussion with local harbor masters and port authorities. This work in California will form the basis for tsunami hazard reduction for all U.S. maritime communities through the National Tsunami Hazard Mitigation Program.

Atomic Energy of Canada (AECL) is the Project Proponent, Public Works and Government Services (PWGSC) is managing the procurement of services and the MMM Group Limited - Conestoga Rovers and Associates Joint Venture (MMM-CRA Joint Venture) is providing detailed design and construction oversight and administration services for the Project. The Port Hope Projectmore » includes the construction of a long-term waste management facility (LTWMF) in the Municipality of Port Hope and the remediation of 18 (eighteen) large-scale LLRW, numerous small-scale sites still being identified and industrial sites within the Municipality. The total volume to be remediated is over one million cubic metres and will come from sites that include temporary storage sites, ravines, beaches, parks, private commercial and residential properties and vacant industrial sites all within the urban area of Port Hope. Challenges that will need to be overcome during this 10 year project include: - Requirements stipulated by the Environmental Assessment (EA) that affect Project logistics and schedule. - Coordination of site remediation with the construction schedule at the LTWMF. - Physical constraints on transport routes and at sites affecting production rates. - Despite being an urban undertaking, seasonal constrains for birds and fish (i.e., nesting and spawning seasons). - Municipal considerations. - Site-specific constraints. - Site interdependencies exist requiring consideration in the schedule. Several sites require the use of an adjacent site for staging. (authors)« less

Vulnerability of port and harbor communities to earthquake and tsunami hazards: The use of GIS in community hazard planning

Wood, Nathan J.; Good, James W.

2004-01-01

AbstractEarthquakes and tsunamis pose significant threats to Pacific Northwest coastal port and harbor communities. Developing holistic mitigation and preparedness strategies to reduce the potential for loss of life and property damage requires community-wide vulnerability assessments that transcend traditional site-specific analyses. The ability of a geographic information system (GIS) to integrate natural, socioeconomic, and hazards information makes it an ideal assessment tool to support community hazard planning efforts. This article summarizes how GIS was used to assess the vulnerability of an Oregon port and harbor community to earthquake and tsunami hazards, as part of a larger risk-reduction planning initiative. The primary purposes of the GIS were to highlight community vulnerability issues and to identify areas that both are susceptible to hazards and contain valued port and harbor community resources. Results of the GIS analyses can help decision makers with limited mitigation resources set priorities for increasing community resiliency to natural hazards.

The aim of this study is to assess the difficulty of intracorporeal suturing in single-port surgery, using experimental suturing model in dry box. Subjects were divided for three groups: seven experienced laparoscopic surgeons, seven surgical residents, and seven interns. An experimental suturing model is developed, and working angle was set from 0° to 90°. The completion rate in 0° was significantly lower than that in the other angles. Completion rate of group A was higher than that of the other groups. Precision of task in group A was significantly higher than that of group B and group C in 0° and 60°. Stress score in 0° were significantly higher than that in the other angles. Our study demonstrated that intracorporeal suturing in single-port surgery seems to be more difficult than conventional laparoscopic surgery. Our data should be taken the institution under consideration for introduction of single-port surgery.

The Apulia region in Italy has the longest Adriatic coastline; thus, maritime tourism is the driving force for its economic development. Pollution risk for four representative touristic ports of the region was assessed by determining the concentrations of 10 metals, 16 polycyclic aromatic hydrocarbons (PAHs) congeners, and the main nutrients. The cumulative mean Effects Range-Median quotient (mERMq) was used to assess the hazard degree, while the distribution patterns and content ratios of different PAH sediment concentrations were investigated to identify the pollution sources. Principal component analyses indicated an anomalous pollution trend for one of the small touristic ports assessed; this trend emerged from contamination by heavy metals and PAHs to a larger extent than expected, considering the main activity in this port, especially in its inner basin. The reason of this anomaly is thought to be the hydrodynamic and/or other stress factors. Copyright © 2016 Elsevier Ltd. All rights reserved.

Subcutaneous implantation type central venous ports(CV ports)are used in chemotherapy. Here, we prospectively examined the frequency of CV port-related infections when the disinfectant was changed from 10% povidone iodine to 1% chlorhexidine ethanol or 70% ethanol. The subjects were patients with malignant tumors, who had newly been implanted with CV ports. We examined CV port-related infections at 1 week after CV port implantation and every 2 weeks thereafter, following sterilization upon insertion of a Huber needle to the CV port. CV port evulsion due to CV port-related infection was noted in 3 patients(4.8%)in whom 15%chlorhexidine ethanol was used(n=62)and in 2 patients(3.3%)in whom 70% ethanol was used(n=60). Infection rates per 1,000 days of CV port use were 1.48% and 1.01%, respectively. Thus, the outcomes of sterilization using 1% chlorhexidine ethanol and 70% ethanol did not differ significantly from those on using 10% povidone iodine for sterilization, based on preliminary results at our institution(3 of 59 patients[5.1%]had port evulsion due to CV port-related infection and the infection rate per 1,000 days of CV port use was 1.47%, Akahane et al, 2012). Chlorhexidine ethanol and ethanol are very convenient to use because they dry quickly and do not need discoloration. Accordingly, chlorhexidine ethanol and ethanol might be useful in CV port management.

The Schizophrenia Patient Outcomes Research Team (PORT) project has played a significant role in the development and dissemination of evidence-based practices for schizophrenia. In contrast to other clinical guidelines, the Schizophrenia PORT Treatment Recommendations, initially published in 1998 and first revised in 2003, are based primarily on empirical data. Over the last 5 years, research on psychopharmacologic and psychosocial treatments for schizophrenia has continued to evolve, warranting an update of the PORT recommendations. In consultation with expert advisors, 2 Evidence Review Groups (ERGs) identified 41 treatment areas for review and conducted electronic literature searches to identify all clinical studies published since the last PORT literature review. The ERGs also reviewed studies preceding 2002 in areas not covered by previous PORT reviews, including smoking cessation, substance abuse, and weight loss. The ERGs reviewed over 600 studies and synthesized the research evidence, producing recommendations for those treatments for which the evidence was sufficiently strong to merit recommendation status. For those treatments lacking empirical support, the ERGs produced parallel summary statements. An Expert Panel consisting of 39 schizophrenia researchers, clinicians, and consumers attended a conference in November 2008 in which consensus was reached on the state of the evidence for each of the treatment areas reviewed. The methods and outcomes of the update process are presented here and resulted in recommendations for 16 psychopharmacologic and 8 psychosocial treatments for schizophrenia. Another 13 psychopharmacologic and 4 psychosocial treatments had insufficient evidence to support a recommendation, representing significant unmet needs in important treatment domains.

Establishing and maintaining public water services in fragile states is a significant development challenge. In anticipation of water infrastructure investments, this study compares drinking water sources and quality between Port Harcourt, Nigeria, and Monrovia, Liberia, two cities recovering from political and economic instability. In both cities, access to piped water is low, and residents rely on a range of other private and public water sources. In Port Harcourt, geographic points for sampling were randomly selected and stratified by population density, whereas in Monrovia, locations for sampling were selected from a current inventory of public water sources. In Port Harcourt, the sampling frame demonstrated extensive reliance on private boreholes and a preference, in both planned and unplanned settlements, for drinking bottled and sachet water. In Monrovia, sample collection focused on public sources (predominantly shallow dug wells). In Port Harcourt, fecal indicator bacteria (FIB) were detected in 25% of sources (N = 566), though concentrations were low. In Monrovia, 57% of sources contained FIB and 22% of sources had nitrate levels that exceeded standards (N = 204). In Monrovia, the convenience of piped water may promote acceptance of the associated water tariffs. However, in Port Harcourt, the high prevalence of self-supply and bottled and sachet drinking water suggests that the consumer's willingness to pay for ongoing municipal water supply improvements may be determined by service reliability and perceptions of water quality. © The American Society of Tropical Medicine and Hygiene.

Increased complexity of scientific research poses new challenges to scientific data management. Meanwhile, scientific collaboration is becoming increasing important, which relies on integrating and sharing data from distributed institutions. We develop SciPort, a Web-based platform on supporting scientific data management and integration based on a central server based distributed architecture, where researchers can easily collect, publish, and share their complex scientific data across multi-institutions. SciPort provides an XML based general approach to model complex scientific data by representing them as XML documents. The documents capture not only hierarchical structured data, but also images and raw data through references. In addition, SciPort provides an XML based hierarchical organization of the overall data space to make it convenient for quick browsing. To provide generalization, schemas and hierarchies are customizable with XML-based definitions, thus it is possible to quickly adapt the system to different applications. While each institution can manage documents on a Local SciPort Server independently, selected documents can be published to a Central Server to form a global view of shared data across all sites. By storing documents in a native XML database, SciPort provides high schema extensibility and supports comprehensive queries through XQuery. By providing a unified and effective means for data modeling, data access and customization with XML, SciPort provides a flexible and powerful platform for sharing scientific data for scientific research communities, and has been successfully used in both biomedical research and clinical trials.

Although single-port donor nephrectomy offers improved cosmetic outcomes, technical challenges have limited its application to selected centers. Our center has performed over 400 single-port donor nephrectomies. The da Vinci single-site robotic platform was utilized in an effort to overcome the steric, visualization, ergonomic, and other technical limitations associated with the single-port approach. Food and Drug Administration device exemption was obtained. Selection criteria for kidney donation included body mass index <35, left kidney donors, and ≤2 renal arteries. After colonic mobilization using standard single-port techniques, the robotic approach was utilized for ureteral complex and hilar dissection. Three cases were performed using the robotic single-site platform. Average total operative time was 262 ± 42 min including 82 ± 16 min of robotic use. Docking time took 20 ± 10 min. Blood loss averaged 77 ± 64 mL. No intraoperative complications occurred, and all procedures were completed with our standard laparoscopic single-port approach. This is the first clinical experience of robotic-assisted donor nephrectomy utilizing the da Vinci single-site platform. Our experience supported the safety of this approach but found that the technology added cost and complexity without tangible benefit. Development of articulating instruments, energy, and stapling devices will be necessary for increased application of robotic single-site surgery for donor nephrectomy. Copyright © 2017 Elsevier Inc.

Real-time control using open source RTOS

Complex telescope systems such as interferometers tend to rely heavily on hard real-time operating systems (RTOS). It has been standard practice at NASA's Jet Propulsion Laboratory (JPL) and many other institutions to use costly commercial RTOSs and hardware. After developing a real-time toolkit for VxWorks on the PowerPC platform (dubbed RTC), the interferometry group at JPL is porting this code to the real-time Application Interface (RTAI), an open source RTOS that is essentially an extension to the Linux kernel. This port has the potential to reduce software and hardware costs for future projects, while increasing the level of performance. The goals of this paper are to briefly describe the RTC toolkit, highlight the successes and pitfalls of porting the toolkit from VxWorks to Linux-RTAI, and to discuss future enhancements that will be implemented as a direct result of this port. The first port of any body of code is always the most difficult since it uncovers the OS-specific calls and forces "red flags" into those portions of the code. For this reason, It has also been a huge benefit that the project chose a generic, platform independent OS extension, ACE, and its CORBA counterpart, TAO. This port of RTC will pave the way for conversions to other environments, the most interesting of which is a non-real-time simulation environment, currently being considered by the Space Interferometry Mission (SIM) and the Terrestrial Planet Finder (TPF) Projects.

A proposed device for combining or switching electromagnetic beams would have three ports, would not contain any moving parts, and would be switchable among three operating states: Two of the ports would be for input; the remaining port would be for output. In one operating state, the signals at both input ports would be coupled through to the output port. In each of the other two operating states, the signal at only one input port would be coupled to the output port. The input port would be selected through choice of the operating state.

A robust and low dead volume world-to-chip interface for thermoplastic microfluidics has been developed. The high pressure fluidic port employs a stainless steel needle inserted into a mating hole aligned to an embedded microchannel, with an interference fit used to increase pressure resistance. Alternately, a self-tapping threaded needle screwed into a mating hole is also demonstrated. In both cases, the flat bottom needle ports seat directly against the microchannel substrate, ensuring low interfacial dead volumes. Low dispersion is observed for dye bands passing the interfaces. The needle ports offer sufficient pull-out forces for applications such as liquid chromatography that require high internal fluid pressures, with the epoxy-free interfaces compatible with internal microchannel pressures above 40 MPa.

An implantable port device provides an easily accessible central route for long-term chemotherapy. Venous catheter migration is one of the rare complications of venous port implantation. It can lead to side effects such as pain in the neck, shoulder, or ear, venous thrombosis, and even life-threatening neurologic problems. To date, there are few published studies that discuss such complications. This retrospective study of venous port implantation in a single center, a Taiwan hospital, was conducted from January 2011 to March 2013. Venous port migration was recorded along with demographic and characteristics of the patients. Of 298 patients with an implantable import device, venous port migration had occurred in seven, an incidence rate of 2.3%. All seven were male and had received the Bard port Fr 6.6 which had smaller size than TYCO port Fr 7.5 and is made of silicon. Significantly, migration occurred in male patients (P = 0.0006) and in those with lung cancer (P = 0.004). Multivariable logistic regression analysis revealed that lung cancer was a significant risk factor for port migration (odds ratio: 11.59; P = 0.0059). The migration rate of the Bard port Fr 6.6 was 6.7%. The median time between initial venous port implantation and port migration was 35.4 days (range, 7 to 135 days) and 71.4% (5/7) of patients had port migration within 30 days after initial port implantation. Male sex and lung cancer are risk factors for venous port migration. The type of venous port is also an important risk factor.

In this study, a geographical information system (GIS) analysis of areas surrounding five ports – Port of New York and New Jersey, Port of Virginia, Port of Savannah, Port of Miami, and Port of Houston – was conducted to characterize the population that might be affected by air emissions from the freight transportation network and to determine which sources had the potential to affect the most people. Defining “near-source” populations as living within 300 m of the freight transportation network, namely the port and associated truck routes, railroads, and intermodal facilities (e. g. rail yards and warehouses); near-source populations ranged from 37,000 to over a million within 10 km of a port. At the ports considered, the population living within 300 m of the port boundary constituted <10 % of the total near-source population. Sensitive population exposure was also indicated, such as the 81 day care centers and K-12 schools in near-source environments within 2 km of the Port of New York and New Jersey. Minority groups constituted 55 % to 85 % of the near-source populations in the five port areas. For four of the five ports, the mean and median income of the near-source population was lower and the minority percentage was higher than the population living adjacent to the near-sou

Midterm outcomes of single port thoracoscopic surgery for major pulmonary resection

2017-01-01

Introduction Single-port thoracoscopic surgery has widened the current minimally invasive surgical techniques toward more less invasive procedures in terms of reducing the number of incisions. However, the current status of oncologic outcome with this technique is not well known for lung cancer surgery. The purpose of this study is to evaluate the oncologic outcomes in early stage lung cancer for impact of the survival outcomes with our experience of conversion to a single-port approach from the conventional three-port approach. Materials and methods Retrospective data of patients who underwent thoracoscopic major lung resection for non-small cell lung cancer between January 2006 and June 2015 were analyzed. Patients’ characteristics, perioperative outcomes, pathologic result, and postoperative follow-up data of thoracoscopic surgery were reviewed and surgical outcomes were compared between conventional three-port (n = 168), two-port (n = 68), and single-port thoracoscopic surgery (n = 203). Results Of the 203 single-port thoracoscopic surgeries, we performed 167 single-port thoracoscopic lobectomy and mediastinal lymph node dissections. During the learning period of each thoracoscopic approach, the mean operation time for single-port thoracoscopic surgery (189±62 min) was not significantly different from those of two-port (175±46 min) and three-port (195±75 min) thoracoscopic lobectomy (p = 0.165). Perioperative outcomes including drain indwelling time (p <0.001), complication (p = 0.185) and conversion event (p = 0.911) were not worsened during learning period with two-port. Midterm survival (p = 0.753) and recurrence free survival (p = 0.656) of single port thoracoscopic lobectomy showed acceptable results compared with two- and three-port approach. Conclusions Single-port thoracoscopic surgery is safe and a feasible option for major lung resection in lung malignancy and this approach following experiences of two-port approach may yield similar oncologic results to those of conventional multi-port approach during thoracoscopic lobectomy.

A new dual impeller centrifugal blood pump has been developed as a research collaboration between Baylor College of Medicine and Institute Dante Pazzanese of Cardiology for long-term left ventricle assist device (LVAD). A design feature of this new pump is a dual impeller that aims to minimize a stagnant flow pattern around the inlet port. Several different materials were tested in order to adopt a double pivot bearing design originally developed by Prof. Dr. Yukihiko Nosé from Baylor College of Medicine. Hydraulic performance tests were conducted with two different inlet ports' angle configurations 30 degrees and 45 degrees . Pump with inlet port angle of 45 degrees achieved best values of pressure ahead and flow after 1800 rpm. Preliminary hemolysis tests were conducted using human blood. The pump showed good performance results and no alarming trace of hemolysis, proving to be a feasible long-term LVAD.

Risk factors associated with surgical site infection (SSI) and the development of short-term complications in macaques undergoing vascular access port (VAP) placement are evaluated in this study. Records from 80 macaques with VAPs were retrospectively reviewed. Logistic regression was used to identify factors associated with short-term post-operative complications. The primary outcome was SSI, which occurred in 21.6% (52.6% in the first 12 months vs. 13% thereafter) of procedures. SSI was associated with major secondary complications including VAP removal (11.4%), wound dehiscence (5.7%), and mechanical catheter occlusion (5.7%). In multivariate modeling, only surgical program progress was a statistically significant predictor of SSI, while animal compliance had a slightly protective effect. Vascular access ports have a moderate risk of complications, provided the surgical program optimizes best practices. Under complex experimental conditions, VAPs represent an important refinement, both improving animals' overall well-being and environment and reducing stress.

Porting the Core Flight System to the Dellingr Cubesat

2017-01-01

Dellingr is a 6U Cubesat developed by NASA Goddard Space Flight Center. It was delivered to the International Space Station in August 2017, and is scheduled to be deployed in November 2017. Compared to a typical NASA satellite, the Dellingr Cubesat had an extremely low budget and short schedule. Although the Dellingr Cubesat has minimal hardware resources, the cFS was ultimately chosen for the flight software. Using the cFS on the Dellingr Cubesat presented a few challenges, but also offered opportunities to help speed up development and verify the ACS flight software. This presentation will cover the lessons learned in porting the cFS to the Dellingr Cubesat, including working with the limited hardware resources, porting the cFS to FreeRTOS, and overcoming limitations related to data storage and file transfer. This presentation will also cover how hardware abstraction was used to run the flight software on multiple platforms and interface with the 42 dynamic simulator.

“Five on a dice” port placement for robot-assisted thoracoscopic right upper lobectomy using robotic stapler

PubMed Central

Chan, Edward Y.

2017-01-01

Early versions of the da Vinci robot system (S and Si) have been used to perform pulmonary lung resection with severe limitations. The lack of a vascular robot stapler required the presence of a trained bedside assistant whose role was to place, manipulate and fire the stapler around major vascular structures. Thus, the techniques developed for the Si robot required a skilled bedside assistant to perform stapling of the hilar structure and manipulation of the lung. With the advent of the da Vinci Xi system with a vascular robot stapler, we postulated that we could develop a new port placement and technique to provide total control for the surgeon during the pulmonary lung resection. We found that the “five on a dice” port placement and technique allows for minimal assistance during the lobectomy with full control by the surgeon. This technique uses the full capability of the Xi robot to make the robot-assisted lobectomy a safe and ergonomic operation. PMID:29312746

Theory of porous catheters and their applications in intraparenchymal infusions.

PubMed

Raghavan, Raghu; Odland, Rick M

2017-01-01

Multiport catheters and catheters with a porous surface have been proposed for intraparenchymal infusions of therapeutics in fluid suspensions. Target diseases include brain cancer and serious neurodegenerative diseases, as well as peripheral tumors, for example in the prostate and the liver. We set up the theory for infusions from such devices, in particular the fluid flow equations which demand a coupling between the flow within the catheter and that in tissue. (Such a coupling is not necessary in the theory of infusion from single port catheters.) The new feature of such catheters, treated by our model, is revealed by infusions into inhomogeneous media. Multiport designs have the potential to overcome the limitation of single port catheters, for which the path of the fluid leaving the port is dominated by the inhomogeneities. We solve these equations for some simple cases to illustrate the key design features of porous catheters that show such advantages. The mathematics required for numerical solution with more realistic assumptions is also developed. We confirm the robustness of such catheters, when the ports are sufficiently resistive, against leakage paths that would compromise the infusions from catheters with one or a few large ports. The methods of this paper can be incorporated into a larger planning system for intraparenchymal infusions involving such devices.

Two-dimensional CFD modeling of wave rotor flow dynamics

1994-01-01

A two-dimensional Navier-Stokes solver developed for detailed study of wave rotor flow dynamics is described. The CFD model is helping characterize important loss mechanisms within the wave rotor. The wave rotor stationary ports and the moving rotor passages are resolved on multiple computational grid blocks. The finite-volume form of the thin-layer Navier-Stokes equations with laminar viscosity are integrated in time using a four-stage Runge-Kutta scheme. Roe's approximate Riemann solution scheme or the computationally less expensive advection upstream splitting method (AUSM) flux-splitting scheme is used to effect upwind-differencing of the inviscid flux terms, using cell interface primitive variables set by MUSCL-type interpolation. The diffusion terms are central-differenced. The solver is validated using a steady shock/laminar boundary layer interaction problem and an unsteady, inviscid wave rotor passage gradual opening problem. A model inlet port/passage charging problem is simulated and key features of the unsteady wave rotor flow field are identified. Lastly, the medium pressure inlet port and high pressure outlet port portion of the NASA Lewis Research Center experimental divider cycle is simulated and computed results are compared with experimental measurements. The model accurately predicts the wave timing within the rotor passages and the distribution of flow variables in the stationary inlet port region.

International trade inoperability input-output model (IT-IIM): theory and application.

PubMed

Jung, Jeesang; Santos, Joost R; Haimes, Yacov Y

2009-01-01

The inoperability input-output model (IIM) has been used for analyzing disruptions due to man-made or natural disasters that can adversely affect the operation of economic systems or critical infrastructures. Taking economic perturbation for each sector as inputs, the IIM provides the degree of economic production impacts on all industry sectors as the outputs for the model. The current version of the IIM does not provide a separate analysis for the international trade component of the inoperability. If an important port of entry (e.g., Port of Los Angeles) is disrupted, then international trade inoperability becomes a highly relevant subject for analysis. To complement the current IIM, this article develops the International Trade-IIM (IT-IIM). The IT-IIM investigates the resulting international trade inoperability for all industry sectors resulting from disruptions to a major port of entry. Similar to traditional IIM analysis, the inoperability metrics that the IT-IIM provides can be used to prioritize economic sectors based on the losses they could potentially incur. The IT-IIM is used to analyze two types of direct perturbations: (1) the reduced capacity of ports of entry, including harbors and airports (e.g., a shutdown of any port of entry); and (2) restrictions on commercial goods that foreign countries trade with the base nation (e.g., embargo).

Risk factors for venous port migration in a single institute in Taiwan

PubMed Central

2014-01-01

Background An implantable port device provides an easily accessible central route for long-term chemotherapy. Venous catheter migration is one of the rare complications of venous port implantation. It can lead to side effects such as pain in the neck, shoulder, or ear, venous thrombosis, and even life-threatening neurologic problems. To date, there are few published studies that discuss such complications. Methods This retrospective study of venous port implantation in a single center, a Taiwan hospital, was conducted from January 2011 to March 2013. Venous port migration was recorded along with demographic and characteristics of the patients. Results Of 298 patients with an implantable import device, venous port migration had occurred in seven, an incidence rate of 2.3%. All seven were male and had received the Bard port Fr 6.6 which had smaller size than TYCO port Fr 7.5 and is made of silicon. Significantly, migration occurred in male patients (P = 0.0006) and in those with lung cancer (P = 0.004). Multivariable logistic regression analysis revealed that lung cancer was a significant risk factor for port migration (odds ratio: 11.59; P = 0.0059). The migration rate of the Bard port Fr 6.6 was 6.7%. The median time between initial venous port implantation and port migration was 35.4 days (range, 7 to 135 days) and 71.4% (5/7) of patients had port migration within 30 days after initial port implantation. Conclusions Male sex and lung cancer are risk factors for venous port migration. The type of venous port is also an important risk factor. PMID:24423026

1999-01-01

A method and apparatus for cold gas reinjection in through-flow and reverse-flow wave rotors having a plurality of channels formed around a periphery thereof. A first port injects a supply of cool air into the channels. A second port allows the supply of cool air to exit the channels and flow to a combustor. A third port injects a supply of hot gas from the combustor into the channels. A fourth port allows the supply of hot gas to exit the channels and flow to a turbine. A diverting port and a reinjection port are connected to the second and third ports, respectively. The diverting port diverts a portion of the cool air exiting through the second port as reinjection air. The diverting port is fluidly connected to the reinjection port which reinjects the reinjection air back into the channels. The reinjection air evacuates the channels of the hot gas resident therein and cools the channel walls, a pair of end walls of the rotor, ducts communicating with the rotor and subsequent downstream components. In a second embodiment, the second port receives all of the cool air exiting the channels and the diverting port diverts a portion of the cool air just prior to the cool air flowing to the combustor.

Effect of varying internal geometry on the static performance of rectangular thrust-reverser ports

NASA Technical Reports Server (NTRS)

Re, Richard J.; Mason, Mary L.

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.

The 2010 Chile and 2011 Japan tsunamis both struck the California coast offering valuable experience and raised a number of significant issues for harbor masters, port captains, and other maritime entities. There was a general call for more planning products to help guide maritime communities in their tsunami response, mitigation, and recovery activities. The State of California is working with the U.S. Federal Emergency Management Agency (FEMA), the U.S. National Tsunami Hazard Mitigation Program (NTHMP), and other tsunami experts to provide communities with new tsunami planning tools to address these issues: Response Playbooks and plans have been developed for ports and harbors identifying potential tsunami current hazards and related damage for various size events. Maps have been generated showing minor, moderate, and severe damage levels that have been linked to current velocity thresholds of 3, 6, and 9 knots, respectively. Knowing this information allows harbor personnel to move ships or strengthen infrastructure prior to the arrival of distant source tsunamis. Damage probability tools and mitigation plans have been created to help reduce tsunami damage by evaluating the survivability of small and large vessels in harbors and ports. These results were compared to the actual damage assessments performed in California and Japan following the 2011 Japanese tsunami. Fragility curves were developed based on current velocity and direction to help harbor and port officials upgrade docks, piles, and related structures. Guidance documents are being generated to help in the development of both local and statewide recovery plans. Additional tools, like post-tsunami sediment and debris movement models, will allow harbors and ports to better understand if and where recovery issues are most likely to occur. Streamlining the regulatory and environmental review process is also a goal of the guidance. These maritime products and procedures are being integrated into guidance through the NTHMP to help other U.S. states/territories/commonwealths develop their own tsunami planning tools. This will lead to more accurate, consistent, and cost-effective tsunami planning strategies within the U.S.

1998-09-01

The purpose of this investigation was to design and implement a prototype physician workstation, called PortFolio, as a platform for developing and evaluating, by means of controlled observer studies, user interfaces and interactive tools for analyzing and managing digital portal images. The first observer study was designed to measure physician acceptance of workstation technology, as an alternative to a view box, for inspection and analysis of portal images for detection of treatment setup errors. The observer study was conducted in a controlled experimental setting to evaluate physician acceptance of the prototype workstation technology exemplified by PortFolio. PortFolio incorporates a windows user interface, a compact kit of carefully selected image analysis tools, and an object-oriented data base infrastructure. The kit evaluated in the observer study included tools for contrast enhancement, registration, and multimodal image visualization. Acceptance was measured in the context of performing portal image analysis in a structured protocol designed to simulate clinical practice. The acceptability and usage patterns were measured from semistructured questionnaires and logs of user interactions. Radiation oncologists, the subjects for this study, perceived the tools in PortFolio to be acceptable clinical aids. Concerns were expressed regarding user efficiency, particularly with respect to the image registration tools. The results of our observer study indicate that workstation technology is acceptable to radiation oncologists as an alternative to a view box for clinical detection of setup errors from digital portal images. Improvements in implementation, including more tools and a greater degree of automation in the image analysis tasks, are needed to make PortFolio more clinically practical.

Magnet-Based System for Docking of Miniature Spacecraft

NASA Technical Reports Server (NTRS)

Howard, Nathan; Nguyen, Hai D.

2007-01-01

A prototype system for docking a miniature spacecraft with a larger spacecraft has been developed by engineers at the Johnson Space Center. Engineers working on Mini AERCam, a free-flying robotic camera, needed to find a way to successfully dock and undock their miniature spacecraft to refuel the propulsion and recharge the batteries. The subsystems developed (see figure) include (1) a docking port, designed for the larger spacecraft, which contains an electromagnet, a ball lock mechanism, and a service probe; and (2) a docking cluster, designed for the smaller spacecraft, which contains either a permanent magnet or an electromagnet. A typical docking operation begins with the docking spacecraft maneuvering into position near the docking port on the parent vehicle. The electromagnet( s) are then turned on, and, if necessary, the docking spacecraft is then maneuvered within the capture envelope of the docking port. The capture envelope for this system is approximated by a 5-in. (12.7-cm) cube centered on the front of the docking-port electromagnet and within an angular misalignment of <30 . Thereafter, the magnetic forces draw the smaller spacecraft toward the larger one and this brings the spacecraft into approximate alignment prior to contact. Mechanical alignment guides provide the final rotational alignment into one of 12 positions. Once the docking vehicle has been captured magnetically in the docking port, the ball-lock mechanism is activated, which locks the two spacecraft together. At this point the electromagnet( s) are turned off, and the service probe extended if recharge and refueling are to be performed. Additionally, during undocking, the polarity of one electromagnet can be reversed to provide a gentle push to separate the two spacecraft. This system is currently being incorporated into the design of Mini AERCam vehicle.

A common factor suppresses thickening in young women with malar area port wine stains and delays low density lipoprotein elevation: is it estrogen?

PubMed

Klapman, M H; Sosa, V B; Yao, J F

2014-06-01

Port wine stains in the malar area of the face can develop thickening in early adult life. We began a study with a hypothesis that this thickening can be associated with elevation of low density lipoprotein. In a retrospective review, we divided 53 subjects with malar port wine stains into 4 groups, adults 25-39 years of age with thickening, that age group without thickening, adults 40+ years of age with thickening, and that age group without thickening. Low density lipoprotein levels in the subjects were compared to age and sex matched controls randomly selected from the general Dermatology clinic. The younger subjects with thickening demonstrated significantly higher low density lipoprotein levels than their controls (p .0082) and without thickening lower low density lipoprotein levels than their controls with great significance (p .00058). The subjects without thickening also consisted mainly of women. The low density lipoprotein levels in the older age groups, whether thickened or not, demonstrated no significant difference in low density lipoprotein levels between subjects and controls. This led to a new hypothesis that there is a factor in a subgroup of young adult women with malar port wine stains that suppresses thickening and delays the elevation of low density lipoprotein and that this factor might be estrogen. The implications of this hypothesis are that it could define a marker for a subset of the population that might be protected from the diseases associated with early elevation of low density lipoprotein and provide a source of cutaneous tissue for studying the basic science of this protection (although limited by cosmetic considerations). Future laboratory research to test the new hypothesis might include testing blood of women with malar port wine stains with or without thickening for estrogen and other sex hormones. It might also include skin biopsies to study receptors for estrogen, other sex hormones, and angiogenic factors in malar port wine stains with or without thickening. Future clinical research might include a long term prospective project to study the development of low density lipoprotein related diseases in women with malar port wine stains with or without thickening over years.

Patient-specific port placement for laparoscopic surgery using atlas-based registration

NASA Astrophysics Data System (ADS)

Laparoscopic surgery is a minimally invasive surgical approach, in which abdominal surgical procedures are performed through trocars via small incisions. Patients benefit by reduced postoperative pain, shortened hospital stays, improved cosmetic results, and faster recovery times. Optimal port placement can improve surgeon dexterity and avoid the need to move the trocars, which would cause unnecessary trauma to the patient. We are building an intuitive open source visualization system to help surgeons identify ports. Our methodology is based on an intuitive port placement visualization module and atlas-based registration algorithm to transfer port locations to individual patients. The methodology follows three steps:1) Use a port placement visualization module to manually place ports in an abdominal organ atlas. This step generates port-augmented abdominal atlas. This is done only once for a given patient population. 2) Register the atlas data with the patient CT data, to transfer the prescribed ports to the individual patient 3) Review and adjust the transferred port locations using the port placement visualization module. Tool maneuverability and target reachability can be tested using the visualization system. Our methodology would decrease the amount of physician input necessary to optimize port placement for each patient case. In a follow up work, we plan to use the transferred ports as starting point for further optimization of the port locations by formulating a cost function that will take into account factors such as tool dexterity and likelihood of collision between instruments.

Ambient Intelligence promises to transform current spaces into electronic environments that are responsive, assistive and sensitive to human presence. Those electronic environments will be fully populated with dozens, hundreds or even thousands of connected devices that share information and thus become intelligent. That massive wave of electronic devices will also invade everyday objects, turning them into smart entities, keeping their native features and characteristics while seamlessly promoting them to a new class of thinking and reasoning everyday objects. Although there are strong expectations that most of the users' needs can be fulfilled without their intervention, there are still situations where interaction is required. This paper presents work being done in the field of human-computer interaction, focusing on smart home environments, while being a part of a larger project called Aging Inside a Smart Home. This initiative arose as a way to deal with a large scourge of our country, where lots of elderly persons live alone in their homes, often with limited or no physical mobility. The project relies on the mobile agent computing paradigm in order to create a Virtual Butler that provides the interface between the elderly and the smart home infrastructure. The Virtual Butler is receptive to user questions, answering them according to the context and knowledge of the AISH. It is also capable of interacting with the user whenever it senses that something has gone wrong, notifying next of kin and/or medical services, etc. The Virtual Butler is aware of the user location and moves to the computing device which is closest to the user, in order to be always present. Its avatar can also run in handheld devices keeping its main functionality in order to track user when s/he goes out. According to the evaluation carried out, the Virtual Butler is assessed as a very interesting and loved digital friend, filling the gap between the user and the smart home. The evaluation also showed that the Virtual Butler concept can be easily ported to other types of possible smart and assistive environments like airports, hospitals, shopping malls, offices, etc. PMID:25102342

Saltstone SDU6 Modeling Study

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

Lee, Si Y.; Hyun, Sinjae

2013-01-10

A new disposal unit, designated as Saltstone Disposal Unit 6 (SDU6), is being designed for support of site accelerated closure goals and salt waste projections identified in the new Liquid Waste System Plan. The unit is a cylindrical disposal cell of 375 ft in diameter and 43 ft in height, and it has a minimum 30 million gallons of capacity. SRNL was requested to evaluate the impact of an increased grout placement height on the flow patterns radially spread on the floor and to determine whether grout quality is impacted by the height. The primary goals of the work aremore » to develop the baseline Computational Fluid Dynamics (CFD) model and to perform the evaluations for the flow patterns of grout material in SDU6 as a function of elevation of grout discharge port and grout rheology. Two transient grout models have been developed by taking a three-dimensional multiphase CFD approach to estimate the domain size of the grout materials radially spread on the facility floor and to perform the sensitivity analysis with respect to the baseline design and operating conditions such as elevation height of the discharge port and fresh grout properties. For the CFD modeling calculations, air-grout Volume of Fluid (VOF) method combined with Bingham plastic and time-dependent grout models were used for examining the impact of fluid spread performance for the initial baseline configurations and to evaluate the impact of grout pouring height on grout quality. The grout quality was estimated in terms of the air volume fraction for the grout layer formed on the SDU6 floor, resulting in the change of grout density. The study results should be considered as preliminary scoping analyses since benchmarking analysis is not included in this task scope. Transient analyses with the Bingham plastic model were performed with the FLUENTTM code on the high performance parallel computing platform in SRNL. The analysis coupled with a transient grout aging model was performed by using ANSYS-CFX code in the parallel computing platform in Mercer University. Recommended operational guidance was developed assuming that local shear rates and flow patterns related to radial spread along the SDU floor can be used as a measure of grout performance and spatial dispersion affected by the grout height and viscosity. The 5 ft height baseline results show that when the 150 gpm grout flow with a 5 Pa yield stress and a 60 cp viscosity is poured down through a 3 inch discharge port, the grout is spread radially up to about 64 ft distance from the pouring center after 2 hours' pouring time. The air volume fraction of the grout layer is about 29% at 5 minutes' transient time, and it is reduced by about 9% in 2 hours' pouring time, resulting in the grout density consisting of about 80% grout and 20% air volume fractions. The sensitivity results show that when the discharge port is located at a higher position, a larger amount of air is trapped inside the layer formed below the discharge port at the early transient time of less than 30 minutes because of the higher impinging momentum of the grout flow on the floor, resulting in the formation of less smooth layer. The results clearly indicate that the radial spread for the 43 ft discharge port is about 10% faster than that of the 5 ft discharge port for the early transient period of 5 minutes. However, for the pouring time longer than half an hour, the discharge port height does not affect the radial distance spread on the disposal floor. When grout quality is related to grout volume fraction, the grout volume fraction for the 43 ft discharge port has lower volume fraction than the 5 ft discharge port for the transient period of the first 5 minutes. However, for the pouring time longer than half an hour, the discharge port height does not affect the grout volume fraction for the layer accumulated on the disposal floor. A modified Bingham plastic model coupled with time-dependent viscosity behavior was developed for conducting the initial scoping calculations to assess the impact of fluid residence time on radial spreading and basic flow patterns. The results for the transient viscosity model show that when grout material becomes more viscous, the thickness of the grout layer accumulated on the floor becomes higher, but the radial distance spread on the horizontal floor becomes smaller. The early transient results for the grout density with about 32% air volume fractions are in reasonable agreement with those of the idealized Bingham plastic model. It is recommended that the current models developed here be benchmarked against the experimental results for critical applications of the modeling results.« less

2010-01-01

If the iris ports or access ports on infant incubators are not sufficiently secure, infants may work their way through the ports and fall. To reduce this risk, users should make sure that the ports are closed securely following each use. When possible, users should pass tubing through the incubator hood's grommets instead of through the larger and potentially less secure iris ports.

To compare acute/late toxicity and biochemical control in contemporaneous prostate cancer patient cohorts treated with hypofractionated postprostatectomy radiation therapy (hypoPORT) or conventional PORT (coPORT). Consecutive patients treated with intensity modulated hypoPORT (2.5 Gy per fraction, median cumulative dose 65 Gy [range, 57.5-70 Gy]) or coPORT (1.8-2.0 Gy per fraction, median cumulative dose 66 Gy [range, 60-74 Gy]) between 2005 and 2016 at 2 institutions constituted the study cohort. Acute toxicity and cumulative late grade 2 and ≥3 genitourinary (GU) and gastrointestinal (GI) toxicity incidences were calculated for all patients using the Kaplan-Meier method and compared between cohorts. Biochemical progression-free survival (bPFS) was calculated in patients with ≥12 months' follow-up. Median follow-up for all 461 patients was 38.6 months. Of the 461 patients, 167 (36%) received hypoPORT, and 294 (64%) patients received coPORT. The hypoPORT cohort had significantly worse baseline urinary incontinence. Acute grade ≥2 GU toxicity was more common after hypoPORT (22% vs 8%) (P = .0001). Late grade ≥3 GU toxicity cumulative incidence at 6 years was 11% (hypoPORT) and 4% (coPORT) (P = .0081). However, hypoPORT was not associated with late grade ≥2 GU toxicity on multivariate analysis (hazard ratio 1.39, 95% confidence interval 0.86-2.34) (P = .18). There was no difference in acute or late GI toxicity. In the subset of patients with ≥12 month's follow-up (n = 364, median follow-up 52 months), 4-year bPFS was 78% (95% CI 69.4-85.0) after hypoPORT (P = .0038) and 65% (95% CI 57.6-71.1) after coPORT. HypoPORT was not significant for bPFS on multivariate analysis (hazard ratio 0.64, 95% CI 0.41-1.02, P = .059). HypoPORT shows promising early biochemical control. After controlling for baseline urinary function, hypoPORT was not associated with greater GU toxicity than coPORT. © 2018 Elsevier Inc. Copyright © 2018 Elsevier Inc. All rights reserved.

Finite element based N-Port model for preliminary design of multibody systems

NASA Astrophysics Data System (ADS)

Sanfedino, Francesco; Alazard, Daniel; Pommier-Budinger, Valérie; Falcoz, Alexandre; Boquet, Fabrice

2018-02-01

This article presents and validates a general framework to build a linear dynamic Finite Element-based model of large flexible structures for integrated Control/Structure design. An extension of the Two-Input Two-Output Port (TITOP) approach is here developed. The authors had already proposed such framework for simple beam-like structures: each beam was considered as a TITOP sub-system that could be interconnected to another beam thanks to the ports. The present work studies bodies with multiple attaching points by allowing complex interconnections among several sub-structures in tree-like assembly. The TITOP approach is extended to generate NINOP (N-Input N-Output Port) models. A Matlab toolbox is developed integrating beam and bending plate elements. In particular a NINOP formulation of bending plates is proposed to solve analytic two-dimensional problems. The computation of NINOP models using the outputs of a MSC/Nastran modal analysis is also investigated in order to directly use the results provided by a commercial finite element software. The main advantage of this tool is to provide a model of a multibody system under the form of a block diagram with a minimal number of states. This model is easy to operate for preliminary design and control. An illustrative example highlights the potential of the proposed approach: the synthesis of the dynamical model of a spacecraft with two deployable and flexible solar arrays.

Ergon-trial: ergonomic evaluation of single-port access versus three-port access video-assisted thoracic surgery.

2015-10-01

Single-port access video-assisted thoracic surgery (VATS), a technique progressively developed from the standard three-port approach in minimally invasive surgery, offers ergonomic advantages but also new challenges for the surgeon. We compared the ergonomics of three-port versus single-port VATS. Posture analysis of surgeons was evaluated during 100 consecutive VATS wedge resections (50 triportal vs. 50 uniportal). Technically demanding procedures (major lung resection) were excluded. Operating table height, monitor height, distance and inclination were adjusted according to operator preference. Body posture was assessed by measuring head-trunk axial rotation and head flexion. Perceived physical strain was self-evaluated on the Borg Category Ratio (CR-10) scale. Mental workload was assessed with the National Aeronautics Space Administration-Task Load indeX (NASA-TLX), a multidimensional tool that rates workloads on six scales (mental, physical and temporal demand; effort; performance; frustration). All procedures were completed without complications. Head-trunk axial rotation was significantly reduced and neck flexion significantly improved in uniportal VATS. Viewing direction significantly declined (p = 0.01), body posture as measured on the Borg CR-10 scale was perceived as more stressful and the NASA-TLX score for overall workload was higher (p = 0.04) during triportal VATS. The NASA-TLX score for frustration was higher with uniportal VATS (p = 0.02), but the score for physical demand was higher in triportal VATS (p = 0.006). The surgeon can maintain a more neutral body posture during uniportal VATS by standing straight and facing the monitor with only minimal neck extension/rotation; however, frustration is greater than with triportal VATS.

Port wine oxidation management: a multiparametric kinetic approach.

PubMed

Martins, Rui Costa; Monforte, Ana Rita; Silva Ferreira, António

2013-06-05

Port wine is a flagship fortified wine of Portugal, which undergoes a particularly long aging period, developing a dynamic sensory profile over time, responsible for several wine categories, which is dependent upon the type of aging (bottle or barrel). Therefore, the quality of the product is dependent upon the chemical mechanisms occurring during the aging process, such as oxidation or Maillard reactions. To attain the desired quality management, it is necessary to understand how technological parameters, such as temperature or oxygen exposure, affect the kinetics of the formation of key odorants, such as sotolon. There is a lack of information about the impact of the storage conditions (oxygen and temperature) on Port wine quality. In this study, the effect of these two parameters were investigated to increase the knowledge database concerning aging management of Port wines. It was found that sotolon formation is highly dependent upon oxygen and temperature. There is however a synergistic effect between these two parameters that could significantly increase the concentration. The kinetic parameters of oxygen, sotolon, and other compounds related to Port aging (cis- and trans-5-hydroxy-2-methyl-1,3-dioxan, 2-furfural, 5-hydroxy-methyl-furfural, and 5-methyl-furfural) are also reported. Kinetic models with Monte Carlo simulations, where the oxygen permeability dispersion and temperature are the parameters under evaluation, were applied. On the basis of the modeling predictions, it would seem that the temperature of a cellar would have a more significant impact on the Port wines stored in containers where the oxygen intake is higher (barrels) when compared to containers with low oxygen permeability (bottles using cork stoppers).

Treatment of the capillary vascular malformation (port-wine stain) in Sturge-Weber syndrome with the use of a laser is helpful cosmetically. However, concerns have been raised that laser obliteration of port-wine stains may result in ocular hypertension. The aim of this study was to review clinical features and management of ocular complications of SWS and assess the effects of dermatological laser treatment on the incidence of glaucoma or ocular hypertension. This retrospective cohort study was conducted in an institutional setting. All patients had involvement of the face. Patients who underwent skin laser to the port-wine vascular malformation were analyzed further. Ocular involvement, glaucoma, and skin laser treatment and the relationship to ocular hypertension/glaucoma were observed. Forty-one Sturge-Weber syndrome patients with port-wine vascular malformation were analyzed. Glaucoma was observed in 24 patients (58.5%) at mean age of 2.9 years (range, 0.0-16.5). Of these, 18 (75.0%) were treated with medical therapy, and 10 (41.7%) required trabeculectomy, with 2 of these requiring Seton implant. Of the 41 patients, 28 (68.3%) underwent laser to face/forehead. Mean age of laser commencement was 5 years (range, 0.4-16.5). Thirteen did not undergo laser treatment. Fourteen of the 28 and 10 of the 13 developed ocular hypertension/glaucoma. This retrospective review did not find evidence to suggest that laser treatment of port-wine vascular malformations causes glaucoma or that it can worsen a preexisting ocular hypertension or glaucoma. Statistical analysis was inconclusive.

A W-band (75-100 GHz) six-port junction network analyzer was constructed from commercially available descrete waveguide components and was used for the direct two-port S-parameter measurement of active three-terminal devices. A comparison between the six-port and a down-converter-type frequency extender for a conventional network analyzer revealed the superior performance of the six-port. The application of the six-port to characterize a 0.1-micron gate-length HEMT at W-band is described, and representative results are presented.

An analytical and experimental study of injection-locked two-port oscillators

NASA Technical Reports Server (NTRS)

Freeman, Jon C.; Downey, Alan N.

1987-01-01

A Ku-band IMPATT oscillator with two distinct output power ports was injection-locked alternately at both ports. The transmission locking bandwidth was nearly the same for either port. The lower free running power port had a reflection locking bandwidth that was narrower than its transmission locking one. Just the opposite was found at the other port. A detailed analytical model for two-port injection-locked oscillators is presented, and its results agree quite well with the experiments. A critique of the literature on this topic is included to clear up misconceptions and errors. It is concluded that two-port injection-locked oscillators may prove useful in certain communication systems.

2017-11-01

A framework is developed for modeling the fundamental impairments in optical datacenter interconnects, i.e., the power loss and the receiver noises. This framework makes it possible, to analyze the trade-offs between data rates, modulation order, and number of ports that can be supported in optical interconnect architectures, while guaranteeing that the required signal-to-noise ratios are satisfied. To the best of our knowledge, this important assessment methodology is not yet available. As a case study, the trade-offs are investigated for three coupler-based top-of-rack interconnect architectures, which suffer from serious insertion loss. The results show that using single-port transceivers with 10 GHz bandwidth, avalanche photodiode detectors, and quadratical pulse amplitude modulation, more than 500 ports can be supported.

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant. The total operative and docking times were 280 and 25 minutes, respectively. The total number of lymph nodes harvested was 36 and the proximal and distal resection margins were 31 and 50 cm, respectively. Single-port plus an additional port robotic surgery for right-sided complete mesocolic excision and intracorporeal anastomosis appears to be feasible and safe. This system can overcome certain limitations of the previous robotic systems and conventional single-port laparoscopic surgery. PMID:27757400

USITER is one of seven partner domestic agencies (DA) contributing components to the ITER project. Four diagnostic port plug packages (two equatorial ports and two upper ports) will be engineered and fabricated by Princeton Plasma Physics Lab (PPPL). Diagnostic port plugs as illustrated in Fig. 1 are large primarily stainless steel structures that serve several roles on ITER. The port plugs are the primary vacuum seal and tritium confinement barriers for the vessel. The port plugs also house several plasma diagnostic systems and other machine service equipment. Finally, each port plug must shield high energy neutrons and gamma photons frommore » escaping and creating radiological problems in maintenance areas behind the port plugs. The optimization of the balance between adequate shielding and the need for high performance, high throughput diagnostics systems is the focus of this paper. Neutronics calculations are also needed for assessing nuclear heating and nuclear damage in the port plug and diagnostic components. Attila, the commercially available discrete-ordinates software package, is used for all diagnostic port plug neutronics analysis studies at PPPL.« less

NASA Astrophysics Data System (ADS)

Eid, F. M.; Sharaf El-Din, S. H.; Alam El-Din, K. A.

1997-05-01

The variation of sea level at 11 stations distributed along the Suez Canal was studied during the period from 1980 to 1986. The ranges of variation in daily mean sea level at Port Said and Port Tawfik are about 60 and 120 cm, respectively. The minimum range of daily variation is at Kantara (47 cm). The fluctuations of the monthly mean sea level between the two ends of the Suez Canal vary from one season to another. From July to December, the sea level at Port Said is higher than that at Port Tawfik, with the maximum difference (10·5 cm) in September. During the rest of the year, the mean sea level at Port Tawfik is higher than that at Port Said, with the maximum difference (31·5 cm) in March. The long-term variations of the annual mean sea level at both Port Said and Port Tawfik for the period from 1923 to 1986 showed a positive trend. The sea level at Port Said increased by about 27·8 cm century -1while it increased by only 9·1 cm century -1at Port Tawfik. This indicates that the difference between sea level at Port Said and Port Tawfik has decreased with time.

To identify risk factors for port infections within 30 days of placement. A retrospective chart review of port placements from 2002-2009 was conducted. Patients who had port removals secondary to infection within the first 30 days of placement were included. This group of patients was compared with a control group of patients with ports with no evidence of infection. For every one patient with a port infection, two control subjects were chosen of the same gender and new port placement during the same month as the corresponding patient with an infected port. From 2002-2009, 4,404 ports were placed. Of the 4,404 patients, 33 (0.7%) were found to have a port infection within 30 days of placement. Compared with the control group, the early infection group had a higher prevalence of leukopenia (21.2% vs 6.1%, P = .039) and thrombocytopenia (33% vs 12%, P = .0158). There was also a higher prevalence of an inpatient hospital stay during port placement and high international normalized ratio in the early infection group. Low preoperative white blood cell and platelet counts were risk factors for early infection. Abnormal coagulation profiles and inpatient access of ports after placement could be additional risk factors. Copyright © 2014 SIR. Published by Elsevier Inc. All rights reserved.

This article develops a Bayesian belief network model for the prediction of accident consequences in the Tianjin port. The study starts with a statistical analysis of historical accident data of six years from 2008 to 2013. Then a Bayesian belief network is constructed to express the dependencies between the indicator variables and accident consequences. The statistics and expert knowledge are synthesized in the Bayesian belief network model to obtain the probability distribution of the consequences. By a sensitivity analysis, several indicator variables that have influence on the consequences are identified, including navigational area, ship type and time of the day. The results indicate that the consequences are most sensitive to the position where the accidents occurred, followed by time of day and ship length. The results also reflect that the navigational risk of the Tianjin port is at the acceptable level, despite that there is more room of improvement. These results can be used by the Maritime Safety Administration to take effective measures to enhance maritime safety in the Tianjin port. © 2016 Society for Risk Analysis.

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."

2018-02-01

In cylinder air motion in a compression ignition engine effects mixing of air-fuel, quality of combustion and emission produced. The primary objective is to design and analyze intake and the exhaust port for a four valve cylinder head to meet higher emission norms for a given diesel engine with two valves. In this work, an existing cylinder head designed for two valves was redesigned with 4 valves. The modern trend also confirms this approach. This is being followed in the design and development of new generation engines to meet the stringent environment norms, competition in market and demand for more fuel-efficient engines. The swirl ratio and flow coefficient were measured for different valve lifts using STAR CCM+. CFD results were validated with the two-valve cylinder experimental results. After validation, a comparison between two-valve and four-valve cylinder head was done. The conversion of two valve cylinder head to 4 valves may not support modern high swirl generating port layout and requires a trade-off between many design parameters.

Using Indium Tin Oxide To Mitigate Dust on Viewing Ports

NASA Technical Reports Server (NTRS)

2008-01-01

NASA plans to use a number of onboard viewing ports to measure lunar regolith in situ and to monitor robotic and human activities on the lunar or Martian surface. Because of the size and abundance of dust particles on these bodies, the potential for dust to occlude viewing ports and windows is high enough to threaten system lifetime and reliability, especially when activities rely on relaying video to either a habitat module or controllers on Earth. This project uses a technology being developed by KSC's Electrostatics and Surface Physics Laboratory to remove dust from windowlike surfaces. The technology applies an alternating electric potential to interlaced electrodes. In this application, we use indium tin oxide (ITO) to create various electrode patterns in order to determine the most reliable pattern for dust removal. This technology has application to systems where optical clarity is important. Specifically, this project considers the in situ resource utilization (ISRU) application of a viewing port for Raman spectroscopy, where the electrode pattern on glass would be coated with a scratch-resistant sapphire film (Al2O3).

2018-04-01

Many organizations of all kinds are using new technologies to assist the acquisition and analysis of data. Seaports are a good example of this trend. Seaports generate data regarding the management of marine traffic and other elements, as well as environmental conditions given by meteorological sensors and buoys. However, this enormous amount of data, also known as Big Data, is useless without a proper system to organize, analyze and visualize it. SmartPort is an online platform for the visualization and management of a seaport data that has been built as a GIS application. This work offers a Rich Internet Application that allows the user to visualize and manage the different sources of information produced in a port environment. The Big Data management is based on the FIWARE platform, as well as "The Internet of Things" solutions for the data acquisition. At the same time, Glob3 Mobile (G3M) framework has been used for the development of map requirements. In this way, SmartPort supports 3D visualization of the ports scenery and its data sources.

Efficacy and safety of a single 2 mg dose or 4 mg double dose of alteplase for 50 occluded chest ports using a unique instillation technique.

PubMed

Sharma, Rajinder P; Ree, Chung Ja; Ree, Alexander

2008-01-01

To evaluate the effectiveness and safety of a single 2 mg dose or a 4 mg double dose of alteplase for restoring function in occluded chest ports. A prospective, open-label, nonblinded study was performed on 40 enrolled patients with a total of 50 chest ports at the Henry Ford Hospital Interventional Radiology Department (Detroid, Michigan, USA). Alteplase (Cathflo Activase; Genentech, USA), a recombinant tissue plasminogen activator produced by recombinant DNA technology, was used to restore the function of 50 occluded chest ports. Occlusion was defined as the inability to withdraw blood freely from the port, or the inability to flush the port easily. A 2 mg (2 mL) dose of alteplase was injected into the port through a Huber needle, using a gentle push and pull technique, and was left to dwell for 30 min. If the port remained occluded after the initial 2 mg alteplase treatment, an additional 2 mg alteplase treatment was administered with the same dwell time of 30 min. If a port had remained occluded despite the above regimen, this outcome would have been considered a failure and the chest port would have required surgical intervention. However, all ports were successfully treated, and no surgical intervention was required. The safety end points included minor or major hemorrhages, such as intracranial hemorrhages, or sepsis. Safety end points were determined by a 24 h follow-up telephone call. Of the 50 chest ports (30 single ports and 10 double ports) treated with alteplase, 36 required 2 mg (72%) and 14 required 4 mg (28%). The efficacy end point was 100% for all chest ports treated, without any adverse events. High efficacy and safety rates of restoring function in occluded chest ports were obtained with 2 mg or 4 mg doses of alteplase. Part of this high efficacy rate may be due to the gentle push and pull technique used in the present study.

Assessing Storm Vulnerabilities and Resilience Strategies: A Scenario-Method for Engaging Stakeholders of Public/Private Maritime Infrastructure

NASA Astrophysics Data System (ADS)

Becker, A.; Burroughs, R.

2014-12-01

This presentation discusses a new method to assess vulnerability and resilience strategies for stakeholders of coastal-dependent transportation infrastructure, such as seaports. Much coastal infrastructure faces increasing risk to extreme events resulting from sea level rise and tropical storms. As seen after Hurricane Sandy, natural disasters result in economic costs, damages to the environment, and negative consequences on resident's quality of life. In the coming decades, tough decisions will need to be made about investment measures to protect critical infrastructure. Coastal communities will need to weigh the costs and benefits of a new storm barrier, for example, against those of retrofitting, elevating or simply doing nothing. These decisions require understanding the priorities and concerns of stakeholders. For ports, these include shippers, insurers, tenants, and ultimate consumers of the port cargo on a local and global scale, all of whom have a stake in addressing port vulnerabilities.Decision-makers in exposed coastal areas need tools to understand stakeholders concerns and perceptions of potential resilience strategies. For ports, they need answers to: 1) How will stakeholders be affected? 2) What strategies could be implemented to build resilience? 3) How effectively would the strategies mitigate stakeholder concerns? 4) What level of time and investment would strategies require? 5) Which stakeholders could/should take responsibility? Our stakeholder-based method provides answers to questions 1-3 and forms the basis for further work to address 4 and 5.Together with an expert group, we developed a pilot study for stakeholders of Rhode Island's critical energy port, the Port of Providence. Our method uses a plausible extreme storm scenario with localized visualizations and a portfolio of potential resilience strategies. We tailor a multi-criteria decision analysis tool and, through a series of workshops, we use the storm scenario, resilience strategies, and decision tool to elicit perceptions and priorities of port stakeholders. Results provide new knowledge to assist decision-makers allocate investments of time, money, and staff resources. We intend for our method to be utilized in other port communities around Rhode Island and in other coastal states.

Ports and harbors are the major vulnerable coastal structures under tsunami attack. Resilient harbors against tsunami impacts are essential for proper, efficient and successful rescue operations and reduction of the loss of life and property by tsunami disasters. There are several critical coastal structures as such in the Marmara Sea. Haydarpasa and Yenikapi ports are located in the Marmara Sea coast of Istanbul. These two ports are selected as the sites of numerical experiments to test their resilience under tsunami impact. Cargo, container and ro-ro handlings, and short/long distance passenger transfers are the common services in both ports. Haydarpasa port has two breakwaters with the length of three kilometers in total. Yenikapi port has one kilometer long breakwater. The accurate resilience analysis needs high resolution tsunami modeling and careful assessment of the site. Therefore, building data with accurate coordinates of their foot prints and elevations are obtained. The high resolution bathymetry and topography database with less than 5m grid size is developed for modeling. The metadata of the several types of structures and infrastructure of the ports and environs are processed. Different resistances for the structures/buildings/infrastructures are controlled by assigning different friction coefficients in a friction matrix. Two different tsunami conditions - high expected and moderate expected - are selected for numerical modeling. The hybrid tsunami simulation and visualization codes NAMI DANCE, STOC-CADMAS System are utilized to solve all necessary tsunami parameters and obtain the spatial and temporal distributions of flow depth, current velocity, inundation distance and maximum water level in the study domain. Finally, the computed critical values of tsunami parameters are evaluated and structural performance of the port components are discussed in regard to a better resilience.

Campbell, Don; Barton, David; Case, Glenn

2013-07-01

The Municipality of Port Hope is located on the northern shores of Lake Ontario approximately 100 km east of Toronto, Ontario, Canada. Starting in the 1930's, radium and later uranium processing by Eldorado Gold Mines Limited (subsequently Eldorado Nuclear Limited) (Eldorado) at their refinery in Port Hope resulted in the generation of process residues and wastes that were disposed of indiscriminately throughout the Municipality until about the mid-1950's. These process residues contained radium (Ra- 226), uranium, arsenic and other contaminants. Between 1944 and 1988, Eldorado was a Federal Crown Corporation, and as such, the Canadian Federal Government has assumed responsibilitymore » for the clean-up and long-term management of the historic waste produced by Eldorado during this period. The Port Hope Project involves the construction and development of a new long-term waste management facility (LTWMF), and the remediation and transfer of the historic wastes located within the Municipality of Port Hope to the new LTWMF. The new LTWMF will consist of an engineered above-ground containment mound designed to contain and isolate the wastes from the surrounding environment for the next several hundred years. The design of the engineered containment mound consists of a primary and secondary composite base liner system and composite final cover system, made up of both natural materials (e.g., compacted clay, granular materials) and synthetic materials (e.g., geo-synthetic clay liner, geo-membrane, geo-textiles). The engineered containment mound will cover an area of approximately 13 hectares and will contain the estimated 1.2 million cubic metres of waste that will be generated from the remedial activities within Port Hope. The LTWMF will also include infrastructure and support facilities such as access roads, administrative offices, laboratory, equipment and personnel decontamination facilities, waste water treatment plant and other ancillary facilities. Preliminary construction activities for the Port Hope LTWMF commenced in 2012 and are scheduled to continue over the next few years. The first cell of the engineered containment mound is scheduled to be constructed in 2015 with waste placement into the Port Hope LTWMF anticipated over the following seven year period.

To evaluate the feasibility of single-port laparoscopic myomectomy with transumbilical morcellation and suturing. Continuing prospective study (Canadian Task Force classification II-3). University hospital. Fifteen patients who underwent single-port laparoscopic myomectomy between September 2008 and October 2009 to remove single or multiple uterine myomas, at least 1 in each patient measuring greater than 4 cm in diameter. All single-port laparoscopic myomectomy procedures were performed by a single surgeon (Dr. Y.W. Kim). Myomas were extracted transumbilically by cutting the myomas into smaller pieces with a knife or a conventional electromechanical morcellator. After making a single 1.5- to 2.0-cm umbilical incision, the single-port system, created with a wound retractor and a surgical glove, was inserted. All operations were performed using conventional rigid straight laparoscopic instruments. Laparoscopic suturing was performed in intramural myomas and some subserosal myomas. Patient mean (SD; range) age was 38.3 (5.6; 29-49) years. The number of myomas per patient was 1.6 (1.4; 1-6). The diameter of the largest myomas was 6.1 (1.5; 4.2-9.6) cm. In 4 patients, only a knife was required for transumbilical extraction of myomas, and in 11 patients, transumbilical morcellation with an electromechanical morcellator with or without a knife was used. Transumbilical drainage tubes were inserted into the pelvic cavity in 11 of 15 patients. Operative time was 96.7 (33.8; 35-150) minutes. The decrease in postoperative hemoglobin concentration was 1.8 (1.2; 0.4-3.6) g/dL. During the operations, no patients required blood transfusion. No patients developed postoperative fever. Neither bowel injury nor urinary tract injury occurred in any patient. The postoperative hospital stay was 3.1 (0.8; 2-4) days. Single-port transumbilical morcellation using a conventional electromechanical morcellator with or without a knife is feasible. Single-port laparoscopic myomectomy is an alternative method with cosmetic advantage. Copyright © 2010 AAGL. Published by Elsevier Inc. All rights reserved.

Production experience with the ATLAS Event Service

NASA Astrophysics Data System (ADS)

Benjamin, D.; Calafiura, P.; Childers, T.; De, K.; Guan, W.; Maeno, T.; Nilsson, P.; Tsulaia, V.; Van Gemmeren, P.; Wenaus, T.; ATLAS Collaboration

The ATLAS Event Service (AES) has been designed and implemented for efficient running of ATLAS production workflows on a variety of computing platforms, ranging from conventional Grid sites to opportunistic, often short-lived resources, such as spot market commercial clouds, supercomputers and volunteer computing. The Event Service architecture allows real time delivery of fine grained workloads to running payload applications which process dispatched events or event ranges and immediately stream the outputs to highly scalable Object Stores. Thanks to its agile and flexible architecture the AES is currently being used by grid sites for assigning low priority workloads to otherwise idle computing resources; similarly harvesting HPC resources in an efficient back-fill mode; and massively scaling out to the 50-100k concurrent core level on the Amazon spot market to efficiently utilize those transient resources for peak production needs. Platform ports in development include ATLAS@Home (BOINC) and the Google Compute Engine, and a growing number of HPC platforms. After briefly reviewing the concept and the architecture of the Event Service, we will report the status and experience gained in AES commissioning and production operations on supercomputers, and our plans for extending ES application beyond Geant4 simulation to other workflows, such as reconstruction and data analysis.

Morcellized Omental Transfer for Severe HIV Facial Wasting

PubMed Central

Bohorquez, Marlon; Podbielski, Francis J.

2013-01-01

Background: A novel surgical technique to reconstruct facial wasting was developed for patients with severe human immunodeficiency virus lipoatrophy and no source of subcutaneous fat for donor material. Fourteen patients underwent endoscopic harvest of omentum, extracorporeal morcellation, and autologous transfer to the face. Methods: Omental fat was harvested using a standard 3-port laparoscopic technique. A mechanical tissue processor created morsels suitable for transfer. Gold-plated, multi-holed catheters delivered living particulate fat to the subcutaneous planes of the buccal, malar, lateral cheek, and temporal regions. Results were evaluated using standardized pre- and postoperative photographs for specific anatomic criteria found along the typical progression of the disease process. Results: Electron microscopy confirmed that morcellized fat retained intact cell walls and was appropriate for autologous transfer. Complications were minor and transient. Patients were discharged home within 24 hours. No patient required open laparotomy. Survival of the adipose grafts was deemed good to excellent in 13 of the 14 cases. Conclusions: Mechanically morcellized omental fat transfer provides a safe option to restore facial volume in those unusual patients with severe wasting and no available subcutaneous tissue for transfer. Consistent anatomic progression of facial wasting permits preoperative classification, counseling of patients, and postoperative evaluation of surgical improvement. PMID:25289268

Microwave plasma ion source with rectangular cavity resonator has been examined to improve ion beam current by changing wave launcher type from single-port to double-port. The cavity resonators with double-port and single-port wave launchers are designed to get resonance effect at TE-103 mode and TE-102 mode, respectively. In order to confirm that the cavities are acting as resonator, the microwave power for breakdown is measured and compared with the E-field strength estimated from the HFSS (High Frequency Structure Simulator) simulation.

In this work, we present an electromagnetic focusing mechanism (EFM), from a commercial webcam, implemented as a delay line of a femtosecond laser pulse characterization system. The characterization system consists on a second order autocorrelator based on a two-photon-absorption detection. The results presented here were performed for two different home-made femtosecond oscillators: Ti:sapph @ 820 nm and highly chirped pulses generated with an Erbium Doped Fiber @ 1550 nm. The EFM applied as a delay line represents an excellent alternative due its performance in terms of stability, resolution, and long scan range up to 3 ps. Due its low power consumption, the device can be connected through the Universal Serial Bus (USB) port. Details of components, schematics of electronic controls, and detection systems are presented.

From full thoracotomy to uniportal video-assisted thoracic surgery: lessons learned

PubMed Central

Passera, Eliseo

2017-01-01

Over the last two decades, conventional video-assisted thoracic surgery (VATS) has established itself as the preferred approach for almost all thoracic surgical procedures. The procedure provides a safe and easy approach with undisputed patient benefit at a cost acceptable to the healthcare system all over the world, in large hospitals as well as underprivileged rural areas. VATS has effectively addressed the patients' right to less scarring, trauma (both of access and intrathoracic manipulation), medication, pain, hospitalization, and early return home and work. These improvements have been further stressed by the introduction of uniportal VATS (uniVATS). Single port surgery is a very exciting new modality in the field of minimal access surgery which aims at further reducing scars of standard vats and towards an hypothetical prospective of scarless surgery.

They analyze the strategies adopted on both occasions, above all isolation measures, port and airport surveillance, and urban interventions. Comparisons are drawn between the actions of federal and local governments, positions taken by doctors and the media, and people's behavior, particularly regarding fear and death. The debaters also analyze the performance of assistance structures, the treatment and prevention measures recommended by public health agencies and private groups with a vested interest in drug sales, and popular and home remedies. The debate extends to how the 1918 experience has influenced the evaluation of today's crisis and what legacy it may leave behind.

An ultra compact triplexing filter was designed based on a silicon on insulator (SOI) nanowire arrayed waveguide grating (AWG) for fiber-to-the-home FTTH. The simulation results revealed that the design performed well in the sense of having a good triplexing function. The designed SOI nanowire AWGs were fabricated using ultraviolet lithography and induced coupler plasma etching. The experimental results showed that the crosstalk was less than -15 dB, and the 3 dB-bandwidth was 11.04 nm. The peak wavelength output from ports a, c, and b were 1455, 1510 and 1300 nm, respectively, which deviated from our original expectations. The deviation of the wavelength is mainly caused by 45 nm width deviation of the arrayed waveguides during the course of the fabrication process and partly caused by material dispersion.

Opara, P I; Eke, G K; Akani, N A

2010-01-01

Sexuality education is the process of acquiring information and forming attitudes and beliefs about sex, sexual identity, relationships and intimacy. It develops young people's skills so that they make informed choices about their behaviour, and feel confident and competent about acting on these choices. It also equips children to face developmental challenges and empowers them against the ills of abuse, exploitation, unwanted pregnancies amongst others. Mothers who are the primary caregivers should be well informed about sexuality issues. The objective of the study is to determine mothers' perception of sexuality education in children, in Port Harcourt. A structured, anonymous and self-administered questionnaire, used as instrument for data collection, was distributed amongst a convenient sample of women attending a Christian women's convention in Port Harcourt. One hundred and fifty eight women participated in the study. Most of them were married (80.4%), and belonged to the 30-49 years age bracket. Seventy one (44.9%) of the respondents had tertiary education. Over 80% agreed that children needed sexuality education but only 15 women (9.5%) had a good knowledge of the concept of sexuality education. One hundred and eleven (70.2%) believed it was the responsibility of both parents to educate their children and over 70% acknowledged that the home was the best place for such education. 64 (40.5%) believed that 6-10 years was the ideal age for starting sex education while 49% thought that the ideal age was 11-15 years. 65% of respondents discussed sexuality issues with their children at least occasionally, the content mostly involved description of body parts and reproductive organs. The average age of menarche amongst respondents was 14.0. One hundred (63%) of the women had prior knowledge of menstruation before menarche. About half of them had received information from their mothers. The study highlights the need for enlightenment of women on sexuality education to enable them empower their against the ills of child abuse.

Poria cocos is one of medical materials frequently used in China and well marketed at home and abroad. Based on the analysis of exports and imports data of P. cocos, we found that large proportions of P. cocos were exported, while only a small proportions of those were imported in China between 2011 and 2016. During periods of these six years, the annual exporting trade of P. cocos in quantity significantly decreased, but that in dollars tend to increase slightly and the unit-prices of P. cocos significantly increased. Statistically, the average annual export trade of P. cocos from 2011 to 2016 in quantity and dollars were 9 279.73 tons and 35.454 million dollars, respectively. And the average annual export in unit-price was 4.14 dollars per kilogram. In total, P. cocos came from 29 provinces and exported to 44 countries through 21 ports. More than 98% of total exports of P. cocos were flew to the markets of countries in Asia, of which Hong Kong was the major partner in import trade of P. cocos. Large amount of P. cocos came from Guangdong province and exported mainly through Shenzhen port. Except the exports, China also imports P. cocos from other countries, among which Korea was the major country exports largest amount of P. cocos to China. And most of P. cocos were imported by Jilin province and mainly through Changchun port. To improve the export kinetic, quality and profits of P. cocos, and thus enhance the international competitiveness of the industry of P. cocos, Chinese governments should emphasize the researches on the products of P. cocos, broaden the demand space of the high-end customers, stimulate the high-end market grow in high speed and accelerate the process of standardization in future.

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

Lukens, J. Nicholas; Lin, Alexander, E-mail: alexander.lin@uphs.upenn.edu; Gamerman, Victoria

Purpose: A subset of patients with oropharyngeal squamous cell carcinoma (OP-SCC) managed with transoral robotic surgery (TORS) and postoperative radiation therapy (PORT) developed soft tissue necrosis (STN) in the surgical bed months after completion of PORT. We investigated the frequency and risk factors. Materials and Methods: This retrospective analysis included 170 consecutive OP-SCC patients treated with TORS and PORT between 2006 and 2012, with >6 months' of follow-up. STN was defined as ulceration of the surgical bed >6 weeks after completion of PORT, requiring opioids, biopsy, or hyperbaric oxygen therapy. Results: A total of 47 of 170 patients (28%) hadmore » a diagnosis of STN. Tonsillar patients were more susceptible than base-of-tongue (BOT) patients, 39% (41 of 104) versus 9% (6 of 66), respectively. For patients with STN, median tumor size was 3.0 cm (range 1.0-5.6 cm), and depth of resection was 2.2 cm (range 1.0-5.1 cm). Median radiation dose and dose of fraction to the surgical bed were 6600 cGy and 220 cGy, respectively. Thirty-one patients (66%) received concurrent chemotherapy. Median time to STN was 2.5 months after PORT. All patients had resolution of STN after a median of 3.7 months. Multivariate analysis identified tonsillar primary (odds ratio [OR] 4.73, P=.01), depth of resection (OR 3.12, P=.001), total radiation dose to the resection bed (OR 1.51 per Gy, P<.01), and grade 3 acute mucositis (OR 3.47, P=.02) as risk factors for STN. Beginning May 2011, after implementing aggressive avoidance of delivering >2 Gy/day to the resection bed mucosa, only 8% (2 of 26 patients) experienced STN (all grade 2). Conclusions: A subset of OP-SCC patients treated with TORS and PORT are at risk for developing late consequential surgical bed STN. Risk factors include tonsillar location, depth of resection, radiation dose to the surgical bed, and severe mucositis. STN risk is significantly decreased with carefully avoiding a radiation dosage of >2 Gy/day to the surgical bed.« less

Incompatibility between the conventional pressurized liquid extraction (PLE) devices and high performance liquid chromatography (HPLC) extensively hinders direct and green chemical analysis of herbal materials. Herein, a facile PLE module was configured, and then it was online hyphenated with HPLC via a turbulent flow chromatography (TFC) column. Regarding PLE module, a long PEEK tube (0.13 × 1000 mm) was employed to generate desired pressure (approximately 13.0 MPa) when warm acidic water (70 °C) was delivered as extraction solvent at a high flow rate (2.5 mL/min), and a hollow guard column (3.0 × 4.0 mm) was implemented to hold crude materials. Effluent was collected from the outlet of PEEK tube, concentrated, and subjected onto HPLC coupled with hybrid ion trap-time of flight mass spectrometer to assess the extraction efficiency and also to profile the chemical composition of Cistanche deserticola (CD) that is honored as "Ginseng of the desert". Afterwards, a TFC column was introduced to accomplish online transmission of low molecule weight components from PLE module to HPLC coupled with diode array detection, and two electronic 6-port/2-channel valves were in charge of alternating the whole system between extraction (0-3.0 min) and elution (3.0-35.0 min) phases. Quantitative method was developed and validated for simultaneous determination of eight primary phenylethanoid glycosides in CD using online PLE-TFC-HPLC. All findings demonstrated that the home-made platform is advantageous at direct chemical analysis, as well as time-, solvent-, and material-savings, suggesting a robust tool for chemical fingerprinting of herbs.

The implanted port vascular access system has provided many patients with safe and reliable vascular access. Its implanted design provides improved body image, reduced maintenance and a better quality of life. The Huber needle has been the standard means of accessing the implanted port system. Because of the problems associated with the Huber needle system, current standards recommend that the Huber needle be changed every 7 days. This evaluation examines the use of a polymer cannula to access the implanted port system. This polymer cannula eliminates many of the problems associated with the Huber needle and provides longer dwell times without increased complications. Seventy nine patients were accessed for a total of 1533 days with the mean dwell time being 19.4 days with no increase in complications associated with port access. To establish implanted port access times of greater than 7 days without increased complications. A multicenter voluntary enrollment evaluation of a medical device. Patients were offered the opportunity to participate in the evaluation if they had an implanted port and were going to be accessed for therapy for periods of 7 days or more. Patients were observed for adverse cutaneous reactions at the insertion site and any port access complications such as sepsis, leakage, changes in portal chamber integrity, and implant pocket integrity. From October 1994 through November 1995, 79 L-Cath for Ports (Luther Medical Products) polymer catheter port access devices (Illustration 1) were inserted in 54 patients. This polymer port access device was used instead of a rigid metal Huber needle for port access. The total number of access days was 1533 days with the mean duration of access being 19.4 days. Two patients experienced blood stream infections while they were accessed with the polymer port access device. These infections ensued with fever of unknown origin as the presenting symptom during neutropenic episodes after chemotherapy treatment. The port access device was removed and the port access device tip was cultured with culture results being negative. No other patients experienced complications related to the port access device. The polymer port access device provided a safe and effective means of extending port access times. This reduced the number of restarts for the patients and could extend portal septum life by exposing the portal septum to fewer accesses.

Optical coupling elements for coherent optical multiport receivers

NASA Astrophysics Data System (ADS)

Langenhorst, Ralf

1992-05-01

Three by three (3 by 3) and four by four (4 by 4) port coupling elements and receivers for heterodyne multiport systems are realized. Commercial (3 by 3) fiber coupling elements were used to achieve a usual (3 by 3) port receiver and a (3 by 3) port receiver in pushpull switching, whose concept was theoretically and experimentally analyzed. It is established that intensity oscillations of laser sources are suppressed by pushpull switching. The influence of thermal noise of opto-electronic input levels is shown to be weaker than in usual (3 by 3) port and (4 by 4) port receivers. Thermal noise effect in pushpull switching is similar to this one in heterodyne receivers. An integrated optical coupling element in LiNbO3 was made with bridge circuit from four waveguide coupling elements and two phase converters, which are electro-optically tunable so that a continuous regulation of intermediate frequency phase can be compensated by temperature variations of the element. To obtain fiber-to-fiber losses lower than a dB, a compact crystal optical coupling element was developed with reference to polarization properties of optical waves. This element supplied the eight necessary intermediate frequency output signals. A direct experimental comparison of bandwidth efficiency of multiport and heterodyne receivers shows a factor two in optical area and a factor three in electrical frequency area.

Tsunamis mainly triggered by impulsive undersea motions are long waves and can propagate a long distance. Thus, they can cause huge casualties not only neighboring countries but also distant countries. Recently, several devastating tsunamis have been occurred around the Pacific Ocean rim. Among them, the Great East Japan tsunami occurred on March 11, 2011 is probably recorded as one of the most destructive tsunamis during last several decades. The Tsunami killed more than 20,000 people (including missing people) and deprived of property damage of approximately 300 billion USD. The eastern coast of the Korean Peninsula has been attacked historically by unexpected tsunami events. These tsunamis were generated by undersea earthquakes occurred off the west coast of Japan. For example, the Central East Sea Tsunami occurred on May 26, 1983 killed 3 people and caused serious property damage at Samcheok Port located at the eastern coast of Korea. Thus, a defense plan against unexpected tsunami strikes is an essential task for the port authority to protect lives of human beings and port facilities. In this study, a master plan of tsunami defense is introduced at Samcheok Port. A tsunami hazard map is also made by employing both propagation and inundation models. Detailed defense efforts are described including the procedure of development of a tsunami hazard map. Keywords: tsunami, hazard map, run-up height, emergency action plan

It is well known that port-wine stains of the upper part of the face may herald abnormalities of the brain or eye in the form of Sturge-Weber syndrome. This study focuses on other extracutaneous anomalies in patients with nevi flammei of the head and neck, giving rise to functional complications. A retrospective study was performed on patients with port-wine stains involving the head and neck area. Records were reviewed for demographic parameters, extent of the lesion, clinical complications, diagnostic measures, previous treatments, ultimate therapeutic approach, and outcome. Nine patients, mean age 50.4 years, with port-wine stains and clinical symptoms due to extracutaneous involvement, were admitted and treated from 2006 to 2009. Major clinical features included macrocheilia in three cases, gingival bleeding in two, dysphonia with globus sensation, painful parotideal swelling with recurrent otitis, painful lingual swelling, recurrent epistaxis, and nasal obstruction in one case each. Cases with lower lip hypertrophy were treated by conventional surgical approaches. Recurrent epistaxis and nasal obstruction due to affected inferior turbinate were treated by Nd:YAG laser therapy, and globus sensation and dysphonia by speech therapy. Patients with gingival affection and recurrent otitis were treated by local ear care. Port-wine stains in the head and neck may develop extracutaneous manifestations causing severe problems. A multimodal and interdisciplinary approach is mandatory for an appropriate treatment.

To determine if severe neutropenia at the time of chest port insertion is a risk factor for port removal and central catheter-associated bloodstream infection (CCABSI) in pediatric patients. From May 2007 to June 2015, 183 consecutive patients (mean age, 9.9 y; range, 0.75-21 y) had a port inserted at a single tertiary pediatric center. Seventy-two had severe neutropenia at the time of port insertion (absolute neutrophil count [ANC] range, 0-500/mm 3 ; mean, 185/mm 3 ). Follow-up until port removal or death and CCABSI events were recorded. Within the first 30 days, similar incidences of CCABSI (12.5% of patients with severe neutropenia [n = 9] vs 4.5% of patients without [n = 5]), port removal for infection (2.8% [n = 2] vs 2.7% [n = 3]), and local port infection (2.8% [n = 2] vs 0.9% [n = 1]) were observed in both groups (P > .05), but the rate of CCABSI per 1,000 catheter-days was higher for patients with severe neutropenia (P = .045). Overall, similar incidences of CCABSI (18.1% [n = 13] vs 16.2% [n = 18]), port removal for infection (2.8% [n = 2] vs 7.2% [n = 8]), local port infection (2.8% [n = 2] vs 2.7% [n = 3]), and CCABSIs per 1,000 catheter-days (0.332 vs 0.400) were observed in both groups (P > .05). Port placement in patients with severe neutropenia can be performed without an increased incidence of port removal for infection. The majority of CCABSIs were successfully treated without port removal. Copyright © 2016 SIR. Published by Elsevier Inc. All rights reserved.

Ports are facing increasing environmental concerns with their importance to the global economy. Numerous studies indicated sediment quality deterioration in ports; however, the deterioration is not discriminated for each port activity. This study investigated a spectrum of contaminants (metals and organic pollutants) in surface sediments at 20 sampling points in Port Ningbo, China, one of the top five world ports by volume. The spectrum of contaminants (metals and organic pollutants) was quantified following marine sediment quality guidelines of China and USA and surface sediment quality was assessed according to thresholds of the two guidelines. Coupling a categorical matrix of port activities with the matrix of sedimentary contaminants revealed that contaminants were highly associated with the port operations. Ship repair posed a severe chemical risk to sediment. Operations of crude oil and coal loadings were two top activities related to organic pollutants in sediments while port operations of ore and container loadings discharged metals. Among the 20 sampling points, Cu, Zn, Pb, and DDT and its metabolites were the priority contaminants influencing sediment quality. Overall, surface sediments in Port Ningbo had relatively low environmental risks but ship repair is an environmental concern that must be addressed. This study provides a practical approach for port activity-related quality assessment of surface sediments in ports that could be applicable in many world sites. Copyright © 2017 Elsevier B.V.

We report a wavelength division multiplexed time-bin entangled photon pair source in telecom wavelength using a 10 μm radius Si ring resonator. This compact resonator has two add ports and two drop ports. By pumping one add port by a continuous laser, we demonstrate an efficient generation of two-wavelength division multiplexed time-bin entangled photon pairs in the telecom C-band, which come out of one drop port, and are then split into the signal and idler photons via a wavelength filter. The resonator structure enhances four-wave mixing for pair generation. Moreover, we demonstrate the double-port pumping where two counter propagating pump lights are injected to generate entanglement from the two drop ports simultaneously. We successfully observe the highly entangled outputs from both two drop ports. Surprisingly, the count rate at each drop port is even increased by twice that of the single-port pumping. Possible mechanisms of this observation are discussed. Our technique allows for the efficient use of the Si ring resonator and widens its functionality for variety of applications.

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

Reactor pressure vessel nozzle

Challberg, Roy C.; Upton, Hubert A.

A nozzle for joining a pool of water to a nuclear reactor pressure vessel includes a tubular body having a proximal end joinable to the pressure vessel and a distal end joinable in flow communication with the pool. The body includes a flow passage therethrough having in serial flow communication a first port at the distal end, a throat spaced axially from the first port, a conical channel extending axially from the throat, and a second port at the proximal end which is joinable in flow communication with the pressure vessel. The inner diameter of the flow passage decreases from the first port to the throat and then increases along the conical channel to the second port. In this way, the conical channel acts as a diverging channel or diffuser in the forward flow direction from the first port to the second port for recovering pressure due to the flow restriction provided by the throat. In the backflow direction from the second port to the first port, the conical channel is a converging channel and with the abrupt increase in flow area from the throat to the first port collectively increase resistance to flow therethrough.

Solids feeder apparatus

Bell, Jr., Harold S.

1979-01-01

This invention sets forth a double-acting piston, which carries a floating piston, and which is reciprocated in a housing, for feeding coal to a high pressure gasifier system. The housing has a plurality of solids (for instance: coal) in-feeding ports and a single discharge port, the latter port being in communication with a high pressure gasifier system. The double-acting piston sequentially and individually communicates each of the in-feeding ports with the discharge port. The floating piston both seals off the discharge port while each in-feeding port is receiving coal or the like, to prevent undue escape of gas from the gasifier system, and translates in the housing, following a discharge of coal or the like into the discharge port, to return gas which has been admitted into the housing back into the gasifier system.

Impact of chemical pollution on expression of stress protein genes in the bass Epinephelus guaga collected from several locations including Suez Oil Production Port (Floating port), Atakah Fishing Port, Adabiya Port and Tawfik Port in Suez Governorate, Egypt, was investigated. In the current study, levels of polycyclic aromatic hydrocarbons (PAHs) in water and fish samples collected from Suez Gulf were assessed. In addition, gills and liver tissues of caught bass fish were used to address the interaction between pollution status and the expression of stress-related genes (Hsp70a, Hsp70b, Hsp47, MT and CYP1A). Our analysis demonstrated that levels of PAHs in Floating and Tawfik ports were higher than those found in the Atakah Fishing Port and the Adabiya Port. In addition, MDA and PC contents were significantly higher in gills and liver tissues collected from Floating and Tawfik ports than those collected from Adabiya and Atakah ports. In correlation to the above results, all fish collected from the Floating and Tawfik ports presented a significant increase in Hsp-, MT- and CYP1A-mRNAs. On the other hand, fish samples collected from the Atakah Fishing and Adabiya ports showed no induction of the stress-related genes transcription in such tissues. In conclusion, the current research demonstrates that remarkable increase in PAH contaminants levels in Floating and Tawfik ports are correlated with the levels stress protein-related genes transcription in E. guaga gills and liver tissues.

Beyond a series of security nets: Applying STAMP & STPA to port security

DOE PAGES

Williams, Adam D.

2015-11-17

Port security is an increasing concern considering the significant role of ports in global commerce and today’s increasingly complex threat environment. Current approaches to port security mirror traditional models of accident causality -- ‘a series of security nets’ based on component reliability and probabilistic assumptions. Traditional port security frameworks result in isolated and inconsistent improvement strategies. Recent work in engineered safety combines the ideas of hierarchy, emergence, control and communication into a new paradigm for understanding port security as an emergent complex system property. The ‘System-Theoretic Accident Model and Process (STAMP)’ is a new model of causality based on systemsmore » and control theory. The associated analysis process -- System Theoretic Process Analysis (STPA) -- identifies specific technical or procedural security requirements designed to work in coordination with (and be traceable to) overall port objectives. This process yields port security design specifications that can mitigate (if not eliminate) port security vulnerabilities related to an emphasis on component reliability, lack of coordination between port security stakeholders or economic pressures endemic in the maritime industry. As a result, this article aims to demonstrate how STAMP’s broader view of causality and complexity can better address the dynamic and interactive behaviors of social, organizational and technical components of port security.« less

In this paper, we built and tested the port camera, a novel, inexpensive, portable, and battery-powered laparoscopic tool that integrates the components of a vision system with a cannula port. This new device 1) minimizes the invasiveness of laparoscopic surgery by combining a camera port and tool port; 2) reduces the cost of laparoscopic vision systems by integrating an inexpensive CMOS sensor and LED light source; and 3) enhances laparoscopic surgical procedures by mechanically coupling the camera, tool port, and liquid crystal display (LCD) screen to provide an on-patient visual display. The port camera video system was compared to two laparoscopic video systems: a standard resolution unit from Karl Storz (model 22220130) and a high definition unit from Stryker (model 1188HD). Brightness, contrast, hue, colorfulness, and sharpness were compared. The port camera video is superior to the Storz scope and approximately equivalent to the Stryker scope. An ex vivo study was conducted to measure the operative performance of the port camera. The results suggest that simulated tissue identification and biopsy acquisition with the port camera is as efficient as with a traditional laparoscopic system. The port camera was successfully used by a laparoscopic surgeon for exploratory surgery and liver biopsy during a porcine surgery, demonstrating initial surgical feasibility.
