  2. Powering light boats

    Energy Technology Data Exchange (ETDEWEB)

    Affolter, J.-F.

    1999-07-01

    This short paper reports on a workshop held in Horw, Switzerland, on the application potential of low-temperature fuel cells. It looks at the increasing interest in small, electrically-driven boats in Europe and, in particular, at the option of powering them with fuel cells. A prototype implementation of a test boat is described. Powered by a 300-watt portable PEFC fuel cell constructed by the Paul Scherrer Institute (PSI) and the University of Applied Science in Solothurn, Switzerland, the boat is part of a project to study the technical feasibility of such drive systems for leisure craft and small boats. The paper addresses hydrogen security questions, energy-efficient drives and controllers, maintenance questions and discusses if a combination of fuel cells and photovoltaics would be viable. Also, the design of the boat's hull and the propellers that are used are looked at critically. The economic viability of fuel-cell powered boats is examined. The authors state that they are convinced that such fuel cell drives could be commercially interesting for larger passenger boats, too.

    2014-12-01

    We describe the inspiration, development, and deployment of a novel cocktail device modeled after a class of water-walking insects. Semi-aquatic insects like Microvelia and Velia evade predators by releasing a surfactant that quickly propels them across the water. We exploit an analogous propulsion mechanism in the design of an edible cocktail boat. We discuss how gradients in surface tension lead to motion across the water's surface, and detail the design considerations associated with the insect-inspired cocktail boat. PMID:24853727

  12. By boat to CERN

    CERN Multimedia

    2009-01-01

    Hello, my name is Jordan Juras. I will be here at CERN for a 2-month period spanning mid-June through mid-August working as Student Journalist for The Bulletin. This is a conventional position, but the manner with which I arrived at CERN is quite the opposite. Sitting at work one May 12th morning, I came across a Bulletin article (No. 20-21/2009) while perusing the LHC website. It was advertising ‘Fisica in Barca in Europe 2009’. They were looking for physicists living along the Mediterranean coast between Lisbon and Genoa to help out with the programme. Though I do not hold the title of physicist, nor do I live in Europe (in fact I live just outside of Harrow, Ontario, Canada), I felt compelled to write an email, expressing my love for physics and my interest in helping out with the programme. To my surprise, my help on board was welcome, and I managed to find some discount airfare and I set out for the South of Italy to meet the boat in Bari. Between Bari and Tries...

    2000-07-01

    This paper published by the University of Applied Science in Yverdon-les-Bains, Switzerland, looks at the development of electrically driven small boats that are powered by fuel cells. The various implementations of the test boats are described. Starting with a 100-watt PEM fuel cell built by the Paul Scherrer Institute (PSI) and the University of Applied Science in Solothurn, Switzerland, for educational purposes, a small pedal-boat was electrified. The paper describes the development of four further prototypes and introduces a new project for a 6-passenger leisure boat powered by a 2 kW PEFC fuel cell. Apart from the fuel cells, various other components such as propellers and control electronics are discussed as are the remaining problems still to be solved before the cells and boats can be marketed. Since they were carried out at a technical university, these projects are said to have provided an excellent way of teaching new technologies to students.

    2012-05-01

    When an ensemble of self-propelled camphor boats move in a one-dimensional channel, they exhibit a variety of collective behaviors. Under certain conditions, the boats tend to cluster together and move in a relatively tight formation. This type of behavior, referred to as clustering or swarming here, is one of three types recently observed in experiment. Similar clustering behavior is also reproduced in simulations based on a simple theoretical model. Here we examine this model to determine the clustering mechanism and the conditions under which clustering occurs. We also propose a method of quantifying the behavior that may be used in future experimental work.

  7. Radio-controlled boat for measuring water velocities and bathymetry

    Science.gov (United States)

    Vidmar, Andrej; Bezak, Nejc; Sečnik, Matej

    2016-04-01

    Radio-controlled boat named "Hi3" was designed and developed in order to facilitate water velocity and bathymetry measurements. The boat is equipped with the SonTek RiverSurveyor M9 instrument that is designed for measuring open channel hydraulics (discharge and bathymetry). Usually channel cross sections measurements are performed either from a bridge or from a vessel. However, these approaches have some limitations such as performing bathymetry measurements close to the hydropower plant turbine or downstream from a hydropower plant gate where bathymetry changes are often the most extreme. Therefore, the radio-controlled boat was designed, built and tested in order overcome these limitations. The boat is made from a surf board and two additional small balance support floats. Additional floats are used to improve stability in fast flowing and turbulent parts of rivers. The boat is powered by two electric motors, steering is achieved with changing the power applied to left and right motor. Furthermore, remotely controlled boat "Hi3" can be powered in two ways, either by a gasoline electric generator or by lithium batteries. Lithium batteries are lighter, quieter, but they operation time is shorter compared to an electrical generator. With the radio-controlled boat "Hi3" we can perform measurements in potentially dangerous areas such as under the lock gates at hydroelectric power plant or near the turbine outflow. Until today, the boat "Hi3" has driven more than 200 km in lakes and rivers, performing various water speed and bathymetry measurements. Moreover, in future development the boat "Hi3" will be upgraded in order to be able to perform measurements automatically. The future plans are to develop and implement the autopilot. With this approach the user will define the route that has to be driven by the boat and the boat will drive the pre-defined route automatically. This will be possible because of the very accurate differential GPS from the Sontek River

  17. Bald Eagle response to boating activity in northcentral Florida

    Science.gov (United States)

    Wood, P.B.

    1999-01-01

    I examined the effects of weekend and weekday boating activity on Bald Eagle (Haliaeetus leucocephalus) use of three lakes in northcentral Florida during 1988-89. On Lake Lochloosa, which had the highest number of boats of the three lakes, boating activity significantly reduced the numbers of all age classes of eagles using the lake (P < 0.025). Increased boating activity on Lake Wauberg was not related to use by eagles (P = 0.06) likely because boating activity was concentrated during midday while eagles typically foraged early and late in the day. On Newnan's Lake, the number of eagles observed also was not different between weekends and weekdays (P = 0.20). Weekend boating activity did not relate to perch use, habitat use, interactions or age distribution indicating no alteration of eagle behavior patterns. Flush distance did not vary between weekends and weekdays (P = 0.96), but did vary by month (P = 0.0001), with a greater flush distance during months with highest boating activity. Minimal flush distances (x?? = 53m) and lack of measurable effects on behavior suggested that eagles in my study area were tolerant of boat disturbance.

  20. Automatic Boat Identification System for VIIRS Low Light Imaging Data

    Directory of Open Access Journals (Sweden)

    Christopher D. Elvidge

    2015-03-01

    Full Text Available The ability for satellite sensors to detect lit fishing boats has been known since the 1970s. However, the use of the observations has been limited by the lack of an automatic algorithm for reporting the location and brightness of offshore lighting features arising from boats. An examination of lit fishing boat features in Visible Infrared Imaging Radiometer Suite (VIIRS day/night band (DNB data indicates that the features are essentially spikes. We have developed a set of algorithms for automatic detection of spikes and characterization of the sharpness of spike features. A spike detection algorithm generates a list of candidate boat detections. A second algorithm measures the height of the spikes for the discard of ionospheric energetic particle detections and to rate boat detections as either strong or weak. A sharpness index is used to label boat detections that appear blurry due to the scattering of light by clouds. The candidate spikes are then filtered to remove features on land and gas flares. A validation study conducted using analyst selected boat detections found the automatic algorithm detected 99.3% of the reference pixel set. VIIRS boat detection data can provide fishery agencies with up-to-date information of fishing boat activity and changes in this activity in response to new regulations and enforcement regimes. The data can provide indications of illegal fishing activity in restricted areas and incursions across Exclusive Economic Zone (EEZ boundaries. VIIRS boat detections occur widely offshore from East and Southeast Asia, South America and several other regions.

    The Little Boat Girl THIS picture was taken at dusk, onestormy day, half a century ago. On April 21, 1949, one million soldiersof the Chinese People’s Liberation Army, alongmore than 500-kilometers of riverbank, quicklybroke through the "thousand-Li line of defence,"which had been painstakingly built up by theKuomintang, and forced the Changjiang River. At dusk on April 22, boatmen from Yangzhong,an island in the Changjiang River, hurried to thebank to row the follow-up units across. Despitearduous weather, the boatmen’s skill in fightingagainst wind and waves was considerable and, inthe soft lights of sunset, the rows of old woodenboats appeared to be flying on the ChangjiangRiver. A most impressive scene. Among the officers waiting on the riverbank tobe ferried across was one tall soldier, deeplyabsorbed in the sight of a young girl, not far away,

  2. Mercury exposure aboard an ore boat.

    2004-06-01

    Two maritime academy interns (X and Y) were exposed to mercury vapor after spilling a bottle of mercury on the floor in an enclosed storeroom while doing inventory aboard an ore boat. During a 3-day period, intern Y suffered transient clinical intoxication that resolved after he was removed from the environment and he showered and discarded all clothing. His initial serum mercury level dropped from 4 ng/mL to footwear earlier than intern Y. Intern X's continued exposure due to mercury in the contaminated boots during the 2 weeks before hospitalization was presumed to be the cause. Removing his footwear led to resolution of his toxic symptoms and correlated with subsequent lowered serum mercury levels. Chelation was initiated as recommended, despite its uncertain benefit for neurologic intoxication. Mercury is used in the merchant marine industry in ballast monitors called king gauges. New engineering is recommended for ballast monitoring to eliminate this hazard. PMID:15175181

  3. Blending biodiesel in fishing boat fuels for improved fuel characteristics

    Directory of Open Access Journals (Sweden)

    Cherng-Yuan eLin

    2014-02-01

    Full Text Available Biodiesel is a renewable, clean, alternative energy source with advantages such as excellent lubricity, superior biodegradability and high combustion efficiency. Biodiesel is considered for mixing with fishing boat fuels to adjust their fuel characteristics so that toxic pollutants and greenhouse-effect gas emissions from such shipping might be reduced. The effects of blending fishing boat fuels A and B with various weight proportions of biodiesel are experimentally investigated in this study. The results show that biodiesel blending can significantly improve the inferior fuel properties of both fishing boat fuels and particularly fuel B. The flash points of both of these fuels increases significantly with the addition of biodiesel and thus enhances the safety of transporting and storing these blended fuels. The flash point of fishing boat fuel B even increases by 16% with 25 wt% biodiesel blending. The blending of biodiesel with no sulfur content is found to be one of the most effective ways to reduce the high sulfur content of fishing boat fuel, resulting in a reduction in the emission of sulfur oxides. The addition of only 25 wt% biodiesel decreased the sulfur content of the fishing boat fuel by 37%. The high kinematic viscosity of fishing boat fuel B was also observed to be reduced by 63% with the blending of just 25 wt% biodiesel. However, biodiesel blending caused a slight decrease in heating value around 1% to 4.5%.

    2016-10-01

    The self-propulsion of a heavy, superoleophobic, metallic micro-boat carrying a droplet of various aqueous alcohol solutions as a fuel tank is reported. The micro-boat is driven by the solutocapillary Marangoni flow. The jump in the surface tension owing to the condensation of alcohols on the water surface was established experimentally. Maximal velocities of the self-propulsion were registered as high as 0.05m/s. The maximal velocity of the center mass of the boat correlates with the maximal change in the surface tension, due to the condensation of alcohols. The mechanism of the self-locomotion is discussed. The phenomenological dynamic model describing the self-propulsion is reported. PMID:27388132

    Wake energy recovery of a ship's propeller is an important research subject in ship propulsion field. Based on the study on the mechanism analysis and computation method of the hydrodynamic performance of the propeller-rudder-rudder bubble combination, computer simulation system was built and then used to design and simulate four kinds of rudder bubbles, then the model comparison tests with the original rudder was carried out and the sensible factors influencing the energy-saving effects of rudder bubble was also analyzed. On this basis, a further optimized design of the rudder bubble for a fishing boat was put forward, and comparison test on a real boat was then carried out. It is shown that the optimized rudder bubble design can effectively recover wake energy of ships and the rudder bubble installation features a simple operation and high cost-effectiveness, and the energy-saving effect of real boat test achieves 5.1%.

    Kerkez, B.; Wong, B. P.; Balzano, L.; Lipor, J.; Scavia, D.

    2015-12-01

    We present an autonomous system to measure hypoxia at high spatial resolutions. The approach combines a robotic boat, cloud hosted data services, and a suite of adaptive sampling algorithms to minimize the number of samples required to delineate hypoxic extents. The boat lowers sensors into the water column to provide depth profiles of temperature and oxygen concentrations. An adaptive path-planning algorithm continuously analyzes the in-situ observations and directs the boat to its next measurement location. This significantly reduces number of samples compared to a gridded sampling approach, while simultaneously improving the certainty with which the hypoxic regions are delineated. The method has been evaluated on small lakes throughout Michigan and shows significant promise to scale to the Great Lakes, where hypoxia is common occurrence that adversely affects various stakeholder and ecosystems.

  6. Boat sampling technique for assessment of ageing of components

    International Nuclear Information System (INIS)

    Boat sampling technique (BST) is a surface sampling technique, which has been developed for obtaining, in-situ, metal samples from the surface of an operating component without affecting its operating service life. The BST is non-destructive in nature and the sample is obtained without plastic deformation or without thermal degradation of the parent material. The shape and size of the sample depends upon the shape of the cutter and the surface geometry of the parent material. Miniature test specimens are generated from the sample and the specimens are subjected to various tests, viz. Metallurgical Evaluation, Metallographic Evaluation, Micro-hardness Evaluation, sensitisation test, small punch test etc. to confirm the integrity and assessment of safe operating life of the component. This paper highlights design objective of boat sampling technique, description of sampling module, sampling cutter and its performance evaluation, cutting process, boat samples, operational sequence of sampling module, qualification of sampling module, qualification of sampling technique, qualification of scooped region of the parent material, sample retrieval system, inspection, testing and examination to be carried out on the boat samples and scooped region.

    Hydrodynamics in the macrotidal Seine estuary (France) are controlled by the semi-diurnal tidal regime modulated seasonally by the fluvial discharge. Wind effect on sediment transport (through wind waves and swell) is observed at the mouth of the estuary. Over the last century, authorities have put emphasis on facilitating economic exchanges by means of embankment building and increased dredging activity. These developments led to allow and secure sea vessel traffic in the Seine estuary (from its mouth to the port of Rouen, 125 km upstream) but they also resulted in a change of estuarine hydrodynamics and sediment transport features. A riversides restoration policy has been recently started by port authorities. In this context, the objective of the field-based study presented is to connect vessel characteristics (i.e. speed, draft...), boat-generated waves and their sedimentary impacts. Such information will be used by stakeholders to manage riverside. The natural intertidal site of interest is located in the fluvial freshwater part of the Seine estuary characterized by a 4.5 m maximum tidal range. The foreshore slope is gently decreasing and surface sediments are composed of fine to coarse sand with occasional mud drapes. In order to decipher boat-generated events, the sampling strategy is based on continuous ADV measurements coupled with a turbidimeter and an altimeter to study sediment dynamics. These instruments are settled in the lower part of the foreshore (i) to obtain a significant dataset (i.e. oceanic instruments are not measuring in air) on a zone statically affected by boat waves and (ii) because most of boat traffic occurs during early flood or late ebb period. Spatial variations are assessed along a cross-section through grain-size analysis of surface sediments and topography measurements using pole technique. Results enhance hydrodynamic and sedimentary impacts of boat-generated waves compared respectively to tidal and wind effects. Long

    Lignitz, Eberhard; Lustig, Martina; Scheibe, Ernst

    2014-01-01

    Deaths on the water are common in the autopsy material of medicolegal institutes situated on the coast or big rivers and lakes (illustrated by the example of the Institute of Legal Medicine of Greifswald University). They mostly occur during recreational boating activities. Apart from hydro-meteorological influences, human error is the main cause of accidents. Often it is not sufficiently kept in mind whether the boat crew is fit for sailing and proper seamanship is ensured. Drowning (following initial hypothermia) is the most frequent cause of death. Medicolegal aspects are not decisive for ordering a forensic autopsy. As statistics are not compiled in a uniform way, a comparison of the data of different institutions engaged in investigating deaths at sea and during water sports activities is hardly possible, neither on a national nor an international basis--and the reconstruction of aquatic accidents is generally difficult. Fatal accidents can only be prevented by completely clarifying their causes.

    Recreational boating is an important economic activity that can also represent a powerful source of interference for biological communities. The monitoring of the recreational boating in all Marine Protected Areas (MPAs) within the Liguria region was conducted in the 2010 summer season and it allowed to obtain information not provided by any official institution. The collaboration of geographically different MPAs in Liguria has led to the implementation of a monitoring framework of recreational boating, and this has made it possible to develop uniform management strategies for all the Ligurian marine parks. This study identifies the optimal number of boats for each MPAs, the number of boats that can anchor in the various parks without creating any impact on the biocenosis of merit, providing a first characterization of recreational boating in Liguria during the high touristic season and providing management recommendation to each MPAs. Generally, the Ligurian MPAs do not present critical situations, the number of boats in each MPA being below the optimal number, with the exception of Portofino MPA, where in the 12.5 % of monitored days more than 220 boats were counted and the mean density for weekend is 1.19 no boats/ha (4 times higher than weekday). The results confirm the dependence of the boats peaking from the holidays and the months of the summer, but also it highlights other factors that can contribute in the choice of the boaters.

    The solar boat 'Midnight sun' has during the project period been presented and demonstrated at many different events in Sweden. The focus has been on exhibitions for boats, energy and education. There was a great response from visitors but also from various media such as newspapers, radio and television which reported about the solar boat. Solar driven vehicles are a great way to create interest for solar technology. Due to the increased demand for technical improvements and financial efforts we refrained from participating at the solar boat race 'Frisian Solar Challenge' in 2010 in Holland. Instead a solar boat for tourist trade at Fraemby Udde in Falun has been designed and built. The boat will be rented to visitors during the summer period. The electrical components are designed for short trips with a travel time between 3-4 hours. The solar boat at Fraemby Udde shows that it is relatively simple to convert an existing boat to a solar driven boat. Fraemby Udde receives many visitors, so the solar boat will be shown and used by a large number of tourists from Sweden and abroad

    The motion of several self-propelled boats in a narrow channel displays spontaneous pattern formation and kinetic phase transitions. In contrast with previous studies on self-propelled particles, this model does not require stochastic fluctuations and it is experimentally accessible. By varying the viscosity in the system, it is possible to form either a stationary state, correlated or uncorrelated oscillations, or unidirectional flow. Here, we describe and analyze these self organized patterns and their transitions.

    1976-01-01

    An analysis of a hydromechanical system for longitudinal control of a small hydrofoil boat is presented. The system incorporates height and acceleration sensors operating flaps on the foils through a mechanical linkage. Effects of some of the system parameters on the stability and response to waves are shown. The results indicate that the system is capable of providing adequate stability, but the response to stern waves at low frequencies is larger than desired.

    Full Text Available International Boat Show, a business and tourist event, has been held annually in Italian city of Genoa since 1962. The fair is one of the oldest, largest and best known in the field of boating industry worldwide, primarily due to good management of the event and it can serve as case study for domestic fair organizers to improve the quality of their business and services. Since Belgrade is the city of fairs, but compared to Genoa still underdeveloped in terms of trade shows, the following tasks imposed naturally in this study: to determine the relationship of the organizers of Genoa Boat Show in the sector of preparation and fair offer, in the sector of selection and communication with specific target groups (especially visitors, services during the fair and functioning of the city during the fair. During the research the authors have mostly used historical method, comparison, synthesis and the interview method. The results of theoretical research, in addition, may help not only managers of fair shows and of exhibitions, but also to organizers of other events in our country

  2. Dating the Bibong-ri Neolithic site in Korea: Excavating the oldest ancient boat

    International Nuclear Information System (INIS)

    The remains of an ancient wooden boat were unearthed at the Bibong-ri shell mound site. The site was located at Bibong-ri, Bugog-myeon, Changnyeong-gun, Gyeongsangnam-do in South Korea. A substantial fragment of the vessel was discovered in the lowest layer of the site. We collected 17 samples of charcoal and wood from pebble, sand, and shell layers. Sample preparation extracted the carbon from each sample material and converted it into graphite for AMS radiocarbon dating. Radiocarbon dates of the samples indicate that they belong to the Neolithic period and that the boat dates from ca. 5700 BC. To this point, the oldest known boat in the world has been a wooden boat dating from ca. 5500 BC in China. Other ancient boats from around the world include a logboat dating from ca. 3600 BC in Japan and a fleet of wooden boats dating from ca. 3000 BC in Egypt. The Bibong-ri boat is the first boat from the Neolithic period ever found in South Korea and must represent one of the world's oldest known boats.

  3. The behavioural response of Australian fur seals to motor boat noise.

    Directory of Open Access Journals (Sweden)

    Joy S Tripovich

    Full Text Available Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled noise exposure experiments were conducted on breeding Australian fur seals to determine their behavioural response to controlled in-air motor boat noise on Kanowna Island (39°10'S, 146°18'E. Our results show there were significant differences in the seals' behaviour at low (64-70 dB versus high (75-85 dB sound levels, with seals orientating themselves towards or physically moving away from the louder boat noise at three different sound levels. Furthermore, seals responded more aggressively with one another and were more alert when they heard louder boat noise. Australian fur seals demonstrated plasticity in their vocal responses to boat noise with calls being significantly different between the various sound intensities and barks tending to get faster as the boat noise got louder. These results suggest that Australian fur seals on Kanowna Island show behavioural disturbance to high level boat noise. Consequently, it is recommended that an appropriate level of received boat sound emissions at breeding fur seal colonies be below 74 dB and that these findings be taken into account when evaluating appropriate approach distances and speed limits for boats.

    The objectives of this study were to profile the physiological and physical characteristics of elite dragon boat paddlers, to identify characteristics that predict race performance and to quantify the metabolic energy contributions to simulated 200-m and 500-m dragon boat racing. Eleven, national level, male, Japanese dragon boat paddlers completed a battery of tests on a paddling ergometer including an incremental maximal aerobic capacity test, a 2-minute maximal accumulated oxygen deficit (MAOD) test, and simulated 200-m and 500-m races. A physiological and physical profile of subjects was compiled. Results showed that 200-m race performance correlated with flexed arm girth and excess postexercise oxygen consumption (EPOC) measured in the 30 minutes after the MAOD test, whereas 500-m race performance correlated with body fat percentage, relaxed and flexed arm girth, MAOD, EPOC, and peak power during the MAOD test. Stepwise multiple regression revealed that flexed arm girth was the most powerful predictor of 200-m and 500-m race performance, followed by EPOC with the combination of these 2 factors able to explain 74% and 68% of the variance in 200-m and 500-m race performance, respectively. Aerobic energy contributions for 200-m (50 seconds) and 500-m (1 minute 50 seconds) races were (mean (95% confidence intervals)) 52.1% (range, 47.4-56.8%) and 67.5% (range, 60.1-77.8%), respectively. In conclusion, coaches should develop training programs targeted at developing upper-body musculature and increasing anaerobic capacity because these factors are the strongest predictors of 200-m and 500-m race performance. Given the substantial aerobic energy contributions even for a 200-m race event, coaches should aim to increase the maximal aerobic capacity of the paddler in preparation for both 200-m and 500-m events.

  7. Compression fractures of the vertebrae during a "bumpy" boat ride.

    2012-01-31

    INTRODUCTION: Compression fracture of the vertebrae is common, often the result of falls from height and motor vehicle accidents in the younger age groups. It can occur following minor trauma in the elderly and in those with osteoporosis. MATERIALS AND METHODS: We present an interesting case of compression fracture of the vertebral bodies occurring simultaneously in a couple during a boat ride while on holiday. One individual had fracture of the T8, while the other fractured the L1 vertebrae. Both injuries were treated conservatively with Taylor braces. CONCLUSION: We highlight one of the potential hazards of this recreational activity, and the almost identical fracture pattern in this couple.

  2. Comparison of Ferry Boat and Highway Bridge Energy Use

    Directory of Open Access Journals (Sweden)

    Wayne D. Cottrell

    2011-01-01

    Full Text Available Passenger ferries serve a variety of transport needs in the U.S., such as providing vital links across bodies of water, and supplementing highway bridges. In some cases in which there is a ferry connection but no bridge, a bridge would be impractical; in other cases, a bridge might be feasible. The paper compares the energy consumption of ferries and motor vehicles on bridges, to determine which link is more fuel efficient. One finding is that limited data are available on ferry boat fuel consumption: despite there being 208 ferry boat operators in the U.S. as of 2008, only eight were providing energy use data to the National Transit Database. Examinations of three of the systems found that the passenger-MPG of the ferries ranged from 2.61 to 14.00 (1.11 to 5.95 km/L, while that of the motor vehicles on adjacent highway bridge connections ranged from 25.34 to 32.45 (10.77 to 13.79 km/L. Data from the eight systems are used to develop a ferry MPG model. The model is used to show that the Ryer Island and Charles Hall Ferries are less fuel efficient than hypothetical bridges in those locations. The fuel efficiencies and consumptions of the ferries would equal those of motor vehicles on the bridges, however, if smaller vessels were used, and if the frequency of service was reduced.

  3. Quagga and zebra mussel risk via veliger transfer by overland hauled boats

    Directory of Open Access Journals (Sweden)

    Larry B. Dalton

    2013-04-01

    Full Text Available Invasive quagga and zebra mussels (Dreissena rostriformis bugensis and Dreissena polymorpha, respectively pose a great threat to USwaters. Recreational boats constitute a significant risk for spreading the organisms. Recreational boats circulate large amounts of raw waterwhen in use, and if not drained and dried correctly can transport many mussel larvae, called veligers. Veligers experience very high mortality rates; however, the number of potentially transported veligers can be a serious risk to non-infested bodies of water, especially if multiple boats are involved. The risk of veliger transport was calculated for Lake Mead and Lake Michigan using boat capacities for water circulation and specific veliger density data. Results illustrate the importance of draining, drying, and/or decontaminating recreational boats after use.

    2016-05-01

    This paper discusses the development of a racing boat with an hull made of a composite material reinforced by natural fibers. In particular, we report here the design and realization of the boat hull, the assessment of its mechanical performance by means of a computer assisted simulation, and the cost analysis to assess the economic sustainability of the new composite developed. The results have shown that the new composite has a performance comparable with conventional glass fiber reinforced composites employed for the realization of this type of boat, accordingly to the technology employed and the lamination sequence adopted. Moreover, the FEM analysis performed over the skiff of the designed and constructed boat has demonstrated a successful choice of the material for real application, as it was later confirmed by the good performance of the boat in water. Finally, the cost analysis highlighted the economic sustainability of the new composite, allowing a cost saving of over 28% with respect to carbon fiber composites.

    2015-10-01

    Full Text Available Failure of a cracked steering wheel is studied in this paper. Steering wheel, mounted on a speed boat, had cracks emanating from one of the fastener holes until final fracture occurred. Failure analysis, combining experimental and numerical techniques, was performed. Experimentally, fasteners torque moments were measured, visual inspection performed and material type determined (aluminum alloy AA 6061. Additionally, scanning electron microscopy examination was employed to characterize the microstructure of the fractured surface. Using finite element analysis, stress analysis of a cracked steering wheel was conducted. Stress intensities of uncracked and cracked steering wheel were compared to find out about stress concentration points. Possible causes of crack occurrence include excessive fastener torque moment, fretting between fastener and hole combined with poor machining that left marks that serve as potential crack initiation points. Obtained results are valuable for predicting fracture behavior of the cracked steering wheel and can be taken as a reference for design and exploitation process of such component.

  9. Course Keeping Control of an Autonomous Boat using Low Cost Sensors

    Science.gov (United States)

    Yu, Zhenyu; Bao, Xinping; Nonami, Kenzo

    This paper discusses the course keeping control problem for a small autonomous boat using low cost sensors. Comparing with full scale ships, a small boat is more sensitive to the environmental disturbances because of its small size and low inertia. The sensors available in the boat are a low cost GPS and a rate gyro while the commonly used compass in ship control is absent. The combined effect from disturbance, poor accuracy and significant delay in GPS measurement makes it a challenging task to achieve good performance. In this paper, we propose a simple dynamic model for the boat's horizontal motion. The model is based on the Nomoto's model and can be seen as an extension to it. The model describes the dynamics between rudder deflection and the boat's velocity vector angle while Nomoto's model reveals that between rudder deflection and the boat's yaw angle. With the proposed model there is no need for a yaw sensor for control if the boat's moving direction can be measured. GPS is a convenient device for that job. Based on the derived model, we apply mixed H2/H∞ control method to design the controller. It can guarantee the robust stability, and as the same time it can optimize the performance in the sense of H2 norm. The experimental data show that the proposed approach is proved to be effective and useful.

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Three decades ago Detlev Ellmers suggested that hide (skin boats were being used to hunt swimming reindeer in glacial lakes of northern Germany's Upper Palaeolithic. This paper presents new material in support of Ellmers' contention. A paleo-osteological study from Stellmoor suggests that arrows were directed at the neck and upper shoulders from above and behind, at close range which can be considered evidence of them being shot by hunters in boats as the animals were swimming. Lyngby axes are linked to this hunting technique which provides possible distribution and dating for this proposed early boat technology.

  13. Fuel derived pollutants and boating activity patterns in the Sea of Galilee.

    Science.gov (United States)

    Dinerman, Efrat; Dubowski, Yael; Friedler, Eran

    2011-11-01

    MTBE (Methyl tert-Butyl Ether) is a fuel additive that replaced lead as an antiknock compound in internal combustion motors. Few years after its introduction, detectable levels of MTBE were found in various water bodies. MTBE has a very low taste and odor threshold and is a potential carcinogen. Another group of fuel derived toxic compounds that has been detected in water bodies is BTEX (Benzene, Toluene, Ethylbenzene and Xylene). Boating activity and allochthonous contributions from watersheds are the major sources of fuel derived pollutants in lakes. Their concentrations in lakes thus vary as a function of boating activity intensity, lake surface area and depth, weather and wind regime, land-use in the watershed, etc. The Sea of Galilee (Lake Kinneret) is the only recreational lake in Israel and an important freshwater source. In the current study, a sampling campaign was conducted in order to quantify MTBE and BTEX concentrations in Lake Kinneret, its marinas and its main contributing streams. In addition, a boating-use survey was performed in order to estimate MTBE and BTEX contribution of recreational boating. The sampling campaign revealed that, as expected, MTBE concentrations were higher than BTEX, and that near shore (i.e., marina) concentrations were higher than in-lake concentrations. Despite the clear contribution from boating, high MTBE concentrations were found following a major inflow event in winter, indicating the importance of the allochthonous contribution. The contribution from boating during summer, as measured indirectly by in-lake concentrations, is likely underestimated due to enhanced MTBE volatilization due to strong winds and high temperatures. May-September was found to be the main recreational boating season, with continued boating year round. On average, a single boat is active 23 d/y, with 84% of the watercrafts being active only during weekends and holidays. The survey further indicated that boats stay in the lake for 4.5 h on

    Tributyltin (TBT) and other organotin compounds have been restricted for use on leisure boats since 1989 in the EU. Nonetheless, release of TBT is observed from leisure boats during hull maintenance work, such as pressure hosing. In this work, we used a handheld X-ray Fluorescence analyser (XRF) calibrated for antifouling paint matrixes to measure tin, copper and zinc in antifouling paints coated on leisure boats in Sweden. Our results show that over 10% of the leisure boats (n = 686) contain >400 μg/cm(2) of tin in their antifouling coatings. For comparison, one layer (40 μm dry film) of a TBT-paint equals ≈ 800 μg Sn/cm(2). To our knowledge, tin has never been used in other forms than organotin (OT) in antifouling paints. Thus, even though the XRF analysis does not provide any information on the speciation of tin, the high concentrations indicate that these leisure boats still have OT coatings present on their hull. On several leisure boats we performed additional XRF measurements by progressively scraping off the top coatings and analysing each underlying layer. The XRF data show that when tin is detected, it is most likely present in coatings close to the hull with several layers of other coatings on top. Thus, leaching of OT compounds from the hull into the water is presumed to be negligible. The risk for environmental impacts arises during maintenance work such as scraping, blasting and high pressure hosing activities. The data also show that many boat owners apply excessive paint layers when following paint manufacturers recommendations. Moreover, high loads of copper were detected even on boats sailing in freshwater, despite the more than 20 year old ban, which poses an environmental risk that has not been addressed until now.

    Full Text Available This review paper titled “Robotic-Boat Equipped With Definite Fishing Techniques To Undertake Commercial Fishing” presents a way to develop and fabricate an automated system for commercial fishing. The overall system consists of a robotic boat embedded with desired fishing techniques. The exact location comprising the school of fish is tracked using the remote sensing satellite technology. The remote sensing technology is already existing and is being used for fish tracking. This gives the probable GPS range where the school of fish may be present.Also several fishes present at the bed of the sea which remain immobile for a very long duration of time. These fishes can be tracked using Thermal Imaging Camerasince the temperature of water and the fish will have a considerable difference. Once the GPS location is known the information can be fed into the robotic boat via control station. The updatedGPS location is continuously fed to the Robotic-Boat via Control-Centre and the Robotic-Boat is lead through a definite path to the prescribed GPS location. Once the Robotic-Boat reaches the defined location definite fishing techniques are adopted to undertake the fishing operation. Camera interface can be used to catalyse the fishing operation.

  18. The big crossing: illegal boat migrants in the Mediterranean.

    2014-08-01

    This article explores illegal migration routes and groups across North Africa to Europe. We describe sub-Saharan and cross-Mediterranean routes, and how they changed during the years. We propose an analytical framework for the main factors for these migrations, from local to international and regulatory context. We then describe sea-migrants' nationalities and socio-economic and demographic characteristics, from studies undertook in Tunisia and Morocco. While boat migration represents only a fraction of illegal migration to Europe, it raises humanitarian as well as ethical issues for European and North African (NA) countries, as a non-negligible amount of them end up in death tolls of shipwrecks in the Mediterranean Sea. Moreover, existing statistics show that illegal trans-Mediterranean migration is growing exponentially. Ongoing crises in Africa and the Middle East are likely to prompt even larger outflows of refugees in the near future. This should induce NA countries to share closer public policy concerns with European countries.

  19. New Intelligent Method of Forecasting Control for Fishing Boat Security in the Coastal Area of Fujian

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available To ensure the fishing boat security in the coastal area of Fujian, it is imperative to develop efficient forecasting control system to manage the boats operation in a safe and orderly process. The core issue of establishing the forecasting control system is to predict the relationship of the real time traffic flow and the boat security condition. However, literature review shows that limited reports have addressed on this problem. Hence, a new intelligent forecasting control method base on the Chaos-Particle Swarm Optimization (PSO and Fuzzy Neural Network (FNN is proposed for the short time traffic flow prediction in this paper. The Empirical Mode Decomposition (EMD was first used to denoise the original ship traffic flow observation and then the Chaos-PSO-FNN was applied to the forecasting of the ship traffic flow and hence established the relationship of the real time traffic flow and the boat security condition. The advantage of the proposed approach is that the Chaos-PSO is employed to optimize the FNN parameters to overcome the premature problem of the FNN. As a result, the forecasting control performance is enhanced greatly. In the experiment analysis, the fishing boat traffic information provided by the Fujian marine bureau has been used to evaluate the newly proposed method. The analysis results demonstrate that the proposed Chaos-PSO-FNN method can extract distinct features of the traffic data and the prediction rate is beyond 93.7%. In addition, it found that the fishing boats is supposed to be safe when their travel time avoids the rush time of the traffic flow. This result agrees well with the real data. Thus, the new intelligent forecasting control method for fishing boat security can be used in practice.

  20. The May 2015 boat crisis: the Rohingya in Aceh

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Abstract In May 2015, Indonesia permitted the disembarkation of approximately 1,800 people who had been stranded at sea. The discovery of mass graves in Thailand’s Sadao district, on the border with Malaysia, led to a crack down on people smugglers by the Thai and Malaysian authorities. This saw thousands of Rohingya left stranded at sea as smugglers abandoned their human cargo. While initially pushed back by the Indonesian navy, after being rescued by Indonesian fishermen the Rohingya, on the three boats rescued, were permitted to stay in Indonesia’s Aceh province and seek protection. As part of an Amnesty International research team, conducting research in Aceh in August 2015, our aim was to document the reasons driving the Rohingya to leave Myanmar and Bangladesh, the human rights abuses they experienced at sea and the conditions they are experiencing in Aceh. The subsequent Amnesty International report primarily documented the abuses suffered by those on board the smuggling/trafficking vessels. It also highlighted a number of issues now facing those allowed to remain in Aceh (Amnesty International, 2015. This article will further examine the human rights situation facing the Rohingya in Aceh, why they have been treated differently from previous Rohingya groups who have arrived in Aceh and the ongoing sustainability of the current model. Significantly, the majority of those that arrived have subsequently escaped from the “sites”[1], having again engaged smugglers to reach Malaysia. Given that a process already exists for refugees arriving in Indonesia, the differing treatment received by the Rohingya arriving in May 2015 raises a number of questions. This paper will conclude that the current situation is not sustainable and the treatment of refugees in Aceh should be included in a broader national approach commensurate to the treatment of refugees and asylum seekers throughout Indonesia.

    Full Text Available This paper activates a mode of spatial inquiry into Australia’s identity through an analysis of a number of frames through which the passage and interdiction of boats off the coast of the nation may be viewed. In particular, I explore the way in which Australia’s paradoxical geographical location as South of both the West and Asia play a key role in affixing the horizon within which a conception of the nation and its relationship with the world was – and continues to be – defined and shaped. Moreover, I not only critically probe the constitutive fears and anxieties that underlie bounded conceptions of the trope of the South, but also to examine how such a trope can articulate itself as a site of exchange and negotiation, a distinctive borderland that engenders new cartographies of difference and belonging in an increasingly globalised and interconnected world. I show how these frames overlap and converge on the wider questions of space, place and identity at the very moment when the process of globalisation and migration has done so much to shake any certainties about Australia’s identity as a geographically distinct and spatially bounded nation-state. In so doing, they represent crucial sites for articulating and enacting a transcultural politics of mobility and spatiality that attends to the ways in which the trope of the South may been imagined not as a sphere of containment or an enclaved territory, but as an evolving cartography, the shifting outlines of which opens up new horizons of possibility for rethinking the spatial and temporal coordinates of Australia in a globalizing world.

    The application of the vertical hoisting jack and wave motion compensation techniques to the salvage of an ancient sunken boat is introduced. The boat is wooden, loaded with cultural relics. It has been immersed at the bottom of the South China Sea for more than 800 years. In order to protect the structure of the boat and the cultural relics inside to the largest extent, an open caisson is used to hold the sunken boat and the silts around before they are raised from the seabed all together as a whole. In the paper, first, the seakeeping model test of the system of the salvage barge and the open caisson is done to determine some important wave response parameters. And then a further experimental study of the application of the vertical hoisting jack and wave motion compensation scheme to the salvage of the sunken boat is carried out. In the model tests, the techniques of the integrative mechanic-electronic-hydraulic control, wave motion forecast and wave motion compensation are used to minimize the heave motion of the open caisson. The results of the model tests show that the heave motion of the open caisson can be reduced effectively by the use of the present method.

    2015-03-01

    Measurement of sediment deposition and erosion in coastal areas is a challenge due to soft shifting sediments, but is critical to assessing loss or restoration of coastal sediments and wetlands. The aim of this project was to design and construct a semi-autonomous boat with water depth measuring capabilities. It was intended to map the depth of coastal wetlands to determine erosion rates and assess coastal restoration effects. Depth-measuring equipment was incorporated into an autonomous pontoon boat powered by solar panels. The propulsion system consisted of two paddlewheels and two-way motors to allow movement and positioning for measurements. Modifications included a lightweight, hard coating on the pontoons and powder-coating the frame to extend their usable life. A microcontroller controlled the boat and captured depth data from sensors and location data with a GPS system. The depth measuring system consisted of a pulley and counter system that completed each measurement in less than 45 seconds. This allowed the boat to take approximately 400 measurements per day. Net accuracy was approximately 3 cm in the tested configuration. The boat can continually measure the depth of specified areas in the wetlands; with this data, the change in depth can be monitored to see the effects of restoration projects.

    Ro-Boat is an autonomous river cleaning intelligent robot incorporating mechanical design and computer vision algorithm to achieve autonomous river cleaning and provide a sustainable environment. Ro-boat is designed in a modular fashion with design details such as mechanical structural design, hydrodynamic design and vibrational analysis. It is incorporated with a stable mechanical system with air and water propulsion, robotic arms and solar energy source and it is proceed to become autonomous by using computer vision. Both "HSV Color Space" and "SURF" are proposed to use for measurements in Kalman Filter resulting in extremely robust pollutant tracking. The system has been tested with successful results in the Yamuna River in New Delhi. We foresee that a system of Ro-boats working autonomously 24x7 can clean a major river in a city on about six months time, which is unmatched by alternative methods of river cleaning.

  5. Characteristic oscillatory motion of a camphor boat sensitive to physicochemical environment

    2015-06-01

    A self-propelled camphor boat on water was investigated from the viewpoint of characteristic features of motion and mode-bifurcation depending on the diffusion length of camphor molecules. When a camphor disk was connected to the bottom of a larger plastic plate and then was placed on water, either oscillatory motion (repetition between rest and motion) or continuous motion was observed. In this paper, we report the novel features of this motion and mode-bifurcation as a function of the diffusion length of camphor molecules, e.g., multiple accelerations during oscillation, period-2 or irregular oscillatory motion, and reciprocating oscillation. These characteristic motion and mode-bifurcation are discussed in relation to the diffusion length of camphor molecules under the camphor boat and the development of camphor molecules from the camphor boat on water.

  15. Aliens in Paradise. Boat density and exotic coastal mollusks in Moorea Island (French Polynesia).

    Science.gov (United States)

    Ardura, Alba; Planes, Serge; Garcia-Vazquez, Eva

    2015-12-01

    Pacific islands are particularly vulnerable to the effects of invasive species. After habitat destruction or modification, invasive species are responsible for more biological extinctions than any other cause. Further, the rate of extinction of native species has been higher on islands than anywhere else in the world. Invasive species have also degraded native ecosystems. In order to detect exotic intertidal mollusk species, an extensive sampling around Moorea Island, a more or less unspoiled island surrounded by a rich coral reef habitat, has been developed considering that sampled points have different characteristics in wave exposure, algae coverage, type of substrate, distance to ports, distance to freshwater, distance sewage and boat traffic. Samples were DNA barcoded for unequivocal species assignation. The presence of five NIS among 26 species seems an important signal of introduction of alien biota in Moorea Island coast. However they were represented by a total of 38 individuals among 1487 mollusks (2.55%). While the distance to relatively big ports influenced directly species richness, the intensity of maritime traffic measured as boat density near sampling points was significantly associated with the frequency of exotic species. Other environmental factors did not show significant correlation with the frequency of exotics, suggesting that in an environment without big discontinuities, with little habitat modification, local boat traffic is the most influential factor in the spread of exotic species. This could be mitigated relatively easily by reducing boat density in local zones of ecological interest. PMID:26364683

    Science.gov (United States)

    Jamieson, E.C.; Rennie, C.D.; Jacobson, R.B.; Townsend, R.D.

    2011-01-01

    Detailed mapping of bathymetry and apparent bed load velocity using a boat-mounted acoustic Doppler current profiler (ADCP) was carried out along a 388-m section of the lower Missouri River near Columbia, Missouri. Sampling transects (moving boat) were completed at 5- and 20-m spacing along the study section. Stationary (fixed-boat) measurements were made by maintaining constant boat position over a target point where the position of the boat did not deviate more than 3 m in any direction. For each transect and stationary measurement, apparent bed load velocity (vb) was estimated using ADCP bottom tracking data and high precision real-time kinematic (RTK) global positioning system (GPS). The principal objectives of this research are to (1) determine whether boat motion introduces a bias in apparent bed load velocity measurements; and (2) evaluate the reliability of ADCP bed velocity measurements for a range of sediment transport environments. Results indicate that both high transport (vb>0.6 m/s) and moving-boat conditions (for both high and low transport environments) increase the relative variability in estimates of mean bed velocity. Despite this, the spatially dense single-transect measurements were capable of producing detailed bed velocity maps that correspond closely with the expected pattern of sediment transport over large dunes. ?? 2011 American Society of Civil Engineers.

    This paper presents a model for quantifying the random errors (i.e., variance) of acoustic Doppler current profiler (ADCP) discharge measurements from moving boats for different sampling times. The model focuses on the random processes in the sampled flow field and has been developed using statistical methods currently available for uncertainty analysis of velocity time series. Analysis of field data collected using ADCP from moving boats from three natural rivers of varying sizes and flow conditions shows that, even though the estimate of the integral time scale of the actual turbulent flow field is larger than the sampling interval, the integral time scale of the sampled flow field is on the order of the sampling interval. Thus, an equation for computing the variance error in discharge measurements associated with different sampling times, assuming uncorrelated flow fields is appropriate. The approach is used to help define optimal sampling strategies by choosing the exposure time required for ADCPs to accurately measure flow discharge.

    A passive sonar array designed for tracking diving sperm whales in three dimensions from a single small vessel is presented, and the advantages and limitations of operating this array from a 6 m boat are described. The system consists of four free floating buoys, each with a hydrophone, built-in recorder, and global positioning system receiver (GPS), and one vertical stereo hydrophone array deployed from the boat. Array recordings are post-processed onshore to obtain diving profiles of vocalizing sperm whales. Recordings are synchronized using a GPS timing pulse recorded onto each track. Sensitivity analysis based on hyperbolic localization methods is used to obtain probability distributions for the whale's three-dimensional location for vocalizations received by at least four hydrophones. These localizations are compared to those obtained via isodiachronic sequential bound estimation. Results from deployment of the system around a sperm whale in the Kaikoura Canyon in New Zealand are shown. PMID:19894806

    The Navigable Waters Protection Act (NWPA) was designed to ensure a balance between public rights of navigation and the need to build bridges, dams, and other structures. This paper discussed an owner's guide to navigation safety around water control structures. Developed by Transport Canada, the guide was intended to help owners of water control structures address boating safety matters and assist owners in making applications under the NWPA. The guide was prepared to address amendments made to the NWPA in 2009 as well as to assist owners in identifying potential hazards and interactions by the boating public at water control structures. The guide included information related to signage; navigation aids; barriers and booms; warning alerts and alarms; portage and access around structures; and application requirements. It was concluded that the guide will also provide a summary of legislation that may affect owners of water control structures.

    In order to avoid the illegal use of fishing boat fuel A (FBFA) by traveling diesel vehicles (TDVs) in Taiwan, alternatives that are easily distinguished from premium diesel fuel (PDF) were prepared to evaluate their suitability. Two new ingredients, pyrolysis fuel oil (PFO) and residue of desulfurization unit (RDS), were added into FBFA and formed PFO0.5 and RDS0.5, respectively. Along with FBFA, these three fuels were analyzed for their chemical and physical properties. Furthermore, they were used by three fishing boats with different sizes, output powers, and weights. The engine performances and pollutant emissions were examined and monitored. Experimental results show that there are significant differences in appearance between PDF and the two new blended fuels (PFO0.5 and RDS0.5), and thus misuse or illegal use of FBFA could be substantially reduced. The fuel consumption, which is negatively related to the heating value of fuels, is in order of FBFAfishing boats, using RDS0.5 resulted in a decrease in CO and NO(x) emissions, while the PM emission factors (g bhp(-1) h(-1) and g L(-1)-fuel) were reduced by approximately 36% and 33%, respectively. Owing to the higher total aromatic content in PFO0.5 and RDS0.5, total-PAH concentrations in the exhausts from the three fishing boats using PFO0.5 and RDS0.5 were slightly (1.2 and 1.1 times, respectively) higher than for those using FBFA. Nevertheless, the estimated total BaP(eq) from the three fishing boats using RDS0.5 was 27.5, 19.5, and 8.25% lower than those using FBFA. With using PFO0.5, they were totally different, at 23.5, 2.79, and 2.58% higher. With regard to looking different to PDF, RDS0.5 is superior to PFO0.5, and is thus recommended as a better alternative to FBFA, particularly because it can help lower more emissions of CO, NO(x), PM and BaP(eq).

    The paper describes the deposition of thin films of gallium sulphide on soda-lime glass substrates by thermal evaporation of chemically synthesized powders consisting of gallium sulphide and gallium oxyhydroxide from a Mo or Ta boat and the evolution of their compositional, structural and optical properties on vacuum annealing. The films deposited from Mo or Ta boats possessed distinctly different properties. The Mo-boat evaporated pristine films were amorphous, transparent (α ∼ 10{sup 3} cm{sup −1}) in visible region and had a direct band gap of about 3.2 eV. Vacuum annealing at 723 K brought about their crystallization predominantly into cubic γ-Ga{sub 2}S{sub 3} and a blue shift by about 0.2 eV. The Ta-boat evaporated pristine films were also amorphous but were absorbing (α ∼ 10{sup 4} cm{sup −1}) and had a direct band gap of about 2.1 eV. These crystallized into hexagonal GaS and experienced a blue shift by more than 1.0 eV on vacuum annealing at 723 K. The dissimilar properties of the two kinds of films arose mainly from their different atomic compositions. The Mo-boat evaporated pristine films contained Ga and S in ∼1:1 atomic proportions while those prepared using Ta-boat were Ga rich which impaired their transmission characteristics. The former composition favoured the stabilization of S rich gallium sulphide (Ga{sub 2}S{sub 3}) phase while the latter stabilised S deficient species, GaS. Besides inducing crystallization, vacuum annealing at 723 K also caused the diffusion of Ga in excess of atomic composition of the phase formed, into soda-lime glass which improved the optical transmission of the films. Gallium oxyhydroxide, an inevitable co-product of the chemical synthetic process, in the evaporant introduced oxygen and hydrogen impurities in the films which do not seem to significantly influence their optical properties. - Highlights: • Gallium sulphide films are prepared by thermal evaporation from a Mo or Ta boat. • Mo-boat

    Khlong (canal) boats are a unique mass transport alternative in the congested city of Bangkok. Canals and rivers provide exclusive transit-ways for reducing the commuting time of thousands of city residents daily. However, as a consequence of the service characteristics and boats design and state of repair, they can represent a potential public health risk and an important source of black carbon and greenhouse gases. This work quantifies commuter exposure to black carbon, CO and noise when waiting for and travelling in these diesel fueled boats. Exposure to toxic pollutants and acute noise is similar or worse than for other transportation modes. Mean black carbon concentrations observed at one busy pier and along the main canal were much higher than ambient concentrations at sites impacted by vehicular traffic. Concentrations of CO were similar to those reported for roadside areas of Bangkok. The equivalent continuous sound levels registered at the landing pier were similar to those reported for roadsides, but values recorded inside the boats were significantly higher. We believe that the boat service is a viable alternative mode of mass transport, but public safety could be improved to provide a high quality service, comparable to modern rail systems or emerging bus rapid transit systems. These investments would also contribute to reduce the emission of black carbon and other greenhouse and toxic pollutants.

    Cetacean-focused tourism in Taiwan has grown rapidly since 1997. This development, measured in terms of both number of tour boats and visitors, has resulted in many resource management challenges stemming from the absence of regulation and scientific data. To fill this void in empirical evidence, we used 464 sighting records from 2002 to 2005 to model the impact of cetacean-focused tourism. Cox proportional hazard analysis indicated cetacean avoidance responses to cetacean watching boats were strongly associated with pod size, mother-calf pairs, and cetacean-vessel distances. Mother-calf pairs abandoned their avoidance tactic by 55% compared to noncalf groups when tour boats approached. Second, the hazard ratio of abundance was 0.996, suggesting that the odds of encountering avoidance responses by the cetaceans decreased by 42% for every 100-member increase in the cetacean pod size. Last, distances maintained by boats from the cetaceans was positively related to avoidance responses (i.e., less avoidance behavior with closer interaction). Based on our findings, we have the following recommendations: (a) limit vessels from approaching mothers with calves, (b) limit vessels from approaching small groups of cetaceans, (c) reduced avoidance behavior to boat traffic may be a red flag for potential long-term disturbance, and (d) apply the "precautionary principle" based on the best scientific information available in cetacean-based tourism in Taiwan. These recommendations will help contribute to the sustainable development of cetacean-focused tourism in Taiwan.

    Artificial reefs are commonly used as a management tool, in part to provide ecosystem services, including opportunities for recreational fishing and diving. Quantifying the use of artificial reefs by recreational boaters is essential for determining their value as ecosystem services. In this study, four artificial-natural reef pairs in the eastern Gulf of Mexico (off western Florida) were investigated for boat visitation rates using autonomous acoustic recorders. Digital SpectroGram (DSG) recorders were used to collect sound files from April 2013 to March 2015. An automatic detection algorithm was used to identify boat noise in individual files using the harmonic peaks generated by boat engines, and by comparing the sound amplitude of each file with surrounding files. In all four pairs, visitation rates were significantly higher at the artificial reef than the natural reef. This increase in boat visitation was likely due to actual or perceived increased quality of fishing and diving at the artificial reefs, or to lack of knowledge of the presence or locations of the natural reefs. Inshore reefs (25 m depth). This study appears to be the first to use acoustic data to measure participant use of boating destinations, and highlights the utility of acoustic monitoring for the valuation of this important ecosystem service provided by artificial reefs.

    Full Text Available Interactions with boats can cause several behavioural changes in cetaceans. The purpose of this research is to analyse if Guiana dolphins, Sotalia guianensis, change their surfacing patterns in the presence of different boat categories, and their contact distances to boats at Port of Malhado, Ilheus, Bahia, Brazil. Data were collected from a fixed point from September 2008 to August 2009 and totalled 362.6 h of sampling effort and 213.22 h of effective effort. The number of dolphin breathing events was recorded during one minute periods, every time a boat passed nearby, and the same measurements were performed during periods of boat absence (control. Dolphin group composition was classified into groups with calves and groups without calves. Boat types were classified as inboard motor (IM, outboard motor (OM, ships (S and without a motor (WM. Distances between the dolphins and passing boats were classified as near, intermediate and far. In total, 365 samples of one minute observations in absence of boats, and 379 observations in their presence were collected. Inboard motorboats had the highest occurrence in the study area (n = 478 and in interactions with Guiana dolphins (n = 260. However, outboard motorboats were mainly responsible for the reduction in surface patterns with an average of 1.82 and median of 2.2. In groups with calves, the number of breaths decreased significantly with an average of 2.13 per minute. There were no significant variations concerning the distances in the breathing pattern for any of the boat categories. The variation in the S. guianensis breathing pattern in the presence of boats may be a strategy of boat avoidance or a response to the difficulty of communication between animals.

  13. Bathymetry mapping using a GPS-sonar equipped remote control boat: Application in waste stabilisation ponds

    2014-05-01

    Traditionally, bathymetry mapping of ponds, lakes and rivers have used techniques which are low in spatial resolution, sometimes subjective in terms of precision and accuracy, labour intensive, and that require a high level of safety precautions. In waste stabilisation ponds (WSP) in particular, sludge heights, and thus sludge volume, are commonly measured using a sludge judge (a clear plastic pipe with length markings). A remote control boat fitted with a GPS-equipped sonar unit can improve the resolution of depth measurements, and reduce safety and labour requirements. Sonar devices equipped with GPS technology, also known as fish finders, are readily available and widely used by people in boating. Through the use of GPS technology in conjunction with sonar, the location and depth can be recorded electronically onto a memory card. However, despite its high applicability to the field, this technology has so far been underutilised. In the case of WSP, the sonar can measure the water depth to the top of the sludge layer, which can then be used to develop contour maps of sludge distribution and to determine sludge volume. The coupling of sonar technology with a remotely operative vehicle has several advantages of traditional measurement techniques, particularly in removing human subjectivity of readings, and the sonar being able to collect more data points in a shorter period of time, and continuously, with a much higher spatial resolution. The GPS-sonar equipped remote control boat has been tested on in excess of 50 WSP within Western Australia, and has shown a very strong correlation (R2 = 0.98) between spot readings taken with the sonar compared to a sludge judge. This has shown that the remote control boat with GPS-sonar device is capable of providing sludge bathymetry with greatly increased spatial resolution, while greatly reducing profiling time. Remotely operated vehicles, such as the one built in this study, are useful for not only determining sludge

    It is generally accepted that crew rowing requires perfect synchronization between the movements of the rowers. However, a long-standing and somewhat counterintuitive idea is that out-of-phase crew rowing might have benefits over in-phase (i.e., synchronous) rowing. In synchronous rowing, 5 to 6% of the power produced by the rower(s) is lost to velocity fluctuations of the shell within each rowing cycle. Theoretically, a possible way for crews to increase average boat velocity is to reduce th...

    2014-01-01

    The peculiar images, the boat and the sea, often recur in the poems of Emily Dickinson, the great American poet, which well reflect her internal conflicts, the conflicts between being an autonomous woman and being a passionate yet submissive wom-an. In her poems, the sea is a symbol of the male-dominated society or an individual man. While the little boat is the epitome of Dickinson:sometimes it wants to be strong-willed and clear of its destination, sometimes it just wants to moor in the sea and en-joy the calmness. The paper tends to reveal the psychological struggle of Emily Dickinson and show the whole image of her as an individual through the analysis of the images of boat and sea in Dickinson’s poems.

    Epitaxial layers of silicon are grown on single crystal Si-substrate from a solution of silicon in indium using conventional graphite slider boat technique. The important problems of natural convection due to lower density of silicon compared to indium, poor wetting of substrate due to high angle of contact of indium solution on silicon substrate resulting in poor nucleation, melt removal from the growth substrate and saturation wafer associated with LPE in this technique are practically eliminated using sandwich method with simple modifications of the boat and the method of growth. Some experimental studies on the effect of different surface preparations of growth substrate are also reported. Growth results are shown and discussed. Further, improvization of slider boat to facilitate better study of growth parameters is suggested in the line of modification already carried out.

    The present study tested different sounds that could disturb eagle rays (Aetobatus ocellatus) during their foraging activities at Moorea, French Polynesia. Results showed that artificial white sound and single-frequency tones (40 Hz, 600 Hz or 1 kHz) did not have an effect on rays (at least 90% of rays continued to forage over sand), while playbacks of boat motor sound significantly disturbed rays during foraging activity (60% exhibited an escape behaviour). Overall, our study highlighted the negative effect of boat noises on the foraging activity of eagle rays. These noises produced by boat traffic could, however, have some positive effects for marine aquaculture if they could be used as a deterrent to repel the eagle rays, main predators of the pearl oysters.

    An important European demand for propulsion systems lead us to think that the number of electric ships is growing rapidly. A lot of lakes in Europe are not allowed to the thermal navigation. The aim is to offer a maximum of comfort, reliability, silence, lack of pollution and respect to environment. One of the answers to this expectation is the use of the electric propulsion and a generation of power with fuel cells. After having fabricated the 'Hydroxy100', a single-seater boat propelled by a 100 W fuel cell, and a two-seater boat designed for a 300 W fuel cell, a new plan for a six-seater pleasure boat is being studied. These pilot plans are carried out with the aim to favour the development of this technology. (O.M.)

    Florida's coasts have been transformed over the past three decades as population growth and unprecedented demand for individual shore access to bays and estuaries led to the creation of residential canal developments. Thousands of miles of channels and basins were dredged as a by-product of this urbanization process. The navigable waterways that resulted are now being stressed by increasing boat traffic and canal-side activities. Recognizing their common goal to preserve the recreational and ecological value of southwest Florida waterways, the Florida Department of Environmental Protection, the four-county West Coast Inland Navigation District, and the University of Florida Sea Grant College Program signed a Memorandum of Agreement. The signatories agreed to develop a science-based Regional Waterway Management System (RWMS), which is a new approach to waterway planning and permitting based on carefully mapped channel depths, a census of actual boat populations, and the spatial extent of natural resources. The RWMS provides a comprehensive, regional overview of channel conditions and the geographic distribution and severity of existing impediments to safe navigation and resource protection. RWMS information and analyses result in regional-scale permitting to accommodate water-dependent uses while minimizing environmental impacts and reducing public expenditures. Compared with traditional approaches to waterway management, the science-based RWMS is relatively unbiased, objective, transparent, ecologically sound, and fiscally prudent. PMID:19020927

    Full Text Available All-electric ships are now a standard offering for energy/propulsion systems in boats. In this context, integrating fuel cells (FCs as power sources in hybrid energy systems can be an interesting solution because of their high efficiency and low emission. The energy management strategy for different power sources has a great influence on the fuel consumption, dynamic performance and service life of these power sources. This paper presents a hybrid FC/battery power system for a low power boat. The hybrid system consists of the association of a proton exchange membrane fuel cell (PEMFC and battery bank. The mathematical models for the components of the hybrid system are presented. These models are implemented in Matlab/Simulink environment. Simulations allow analyzing the dynamic performance and power allocation according to a typical driving cycle. In this system, an efficient energy management system (EMS based on operation states is proposed. This EMS strategy determines the operating point of each component of the system in order to maximize the system efficiency. Simulation results validate the adequacy of the hybrid power system and the proposed EMS for real ship driving cycles.

    Development of radio frequency identification (RFID) technology and passive integrated transponder (PIT) tags has substantially increased the ability of researchers and managers to monitor populations of aquatic organisms. However, use of transportable RFID antenna systems (i.e., backpack-mounted) is currently limited to wadeable aquatic environments (RFID antenna to detect individually PIT-tagged benthic aquatic organisms (mussels). We evaluated the effects of tag orientation on detection distances in water with a 32-mm half-duplex PIT tag. Detection distances up to 50 cm from the antenna coils were obtained, but detection distance was dependent on tag orientation. We also evaluated detection distance of PIT tags beneath the sediment to simulate detection of burrowing mussels with 23- and 32-mm tags. In sand substrate, the maximum detection distance varied from 3.5 cm and 4.5 cm (vertical tag orientation) to 24.7 cm and 39.4 cm (45° tag orientation) for the 23- and 32-mm PIT tags, respectively. Our results suggest a 1.4-m total detection width for tagged mussels on the substrate surface by the boat-mounted antenna system regardless of tag orientation. However, burrowed mussels may require multiple passes to increase detection that would be influenced by depth, tag orientation, and tag size. Construction of the boat-mounted antenna was relatively low in cost (<500 USD) and had several advantages (less labor and time intensive, increased safety) over traditional mussel sampling techniques (diving, snorkeling) in nonwadeable habitats.

    High resolution 1H and 13C NMR resonance assignments and conformational assignments were carried out for four (3)-benzyl-(2),(6)-bis(aryl)piperidin-4-ones 1-4 and their four -nitroso-(3)-benzyl-(2),(6)-bis(aryl)piperidin-4-ones 5-8. In addition to conventional 1D NMR methods, 2D shiftcorrelated NMR techniques (1H-1H COSY and 1H-13C COSY) were used for signal assignments. At room temperature the (3)-benzyl-(2),(6)-bis(aryl)piperidin-4-ones 1-4 exist in only one isomeric form whereas their -nitroso derivatives 5-8 exist in two isomeric forms. The preferred conformations of both the isomeric forms of nitrosamines were determined by comparison of the spectral data with those of the corresponding parent amines 1-4 and with the aid of substituent parameters. The results indicate the presence of an equilibrium mixture of boat forms B1 and B2 for Z isomers of 5-8. For the E isomers of 5-8, boat form B1 is predicted to be the major conformer. The piperidin-4-ones 1-4 exist in normal chair conformations with equatorial orientations of all the substituents.

    A camphor tablet, when placed at the air-water interface undergoes sublimation and camphor vapour spreads radially outwards across the surface due to Marangoni forces. This steady camphor influx from tablet onto the air-water interface is balanced by the camphor outflux due to evaporation. When spontaneous fluctuations in evaporation break the axial symmetry of Marangoni force acting radially outwards, the camphor tablet is propelled like a boat along the water surface. We report experiments on the hydrodynamics of a self-propelled camphor boat at air-water interfaces. We observe three different modes of motion, namely continuous, harmonic and periodic, due to the volatile nature of camphor. We explain these modes in terms of ratio of two time-scales: the time-scale over which viscous forces are dominant over the Marangoni forces (τη) and the time-scale over which Marangoni forces are dominant over the viscous forces (τσ). The continuous, harmonic and periodic motions are observed when τη /τσ ~ 1 , τη /τσ >= 1 and τη /τσ >> 1 respectively. Experimentally, the ratio of the time scales is varied by changing the interfacial tension of the air-water interface using Sodium Dodecyl Sulfate. This work was supported by the Collective Interactions Unit, OIST Graduate University.

    2003-01-01

    The use of instruments based on the Doppler principle for measuring water velocity and computing discharge is common within the U.S. Geological Survey (USGS). The instruments and software have changed appreciably during the last 5 years; therefore, the USGS has begun field validation of the instruments used to make discharge measurements from a moving boat. Instruments manufactured by SonTek/YSI and RD Instruments, Inc. were used to collect discharge data at five different sites. One or more traditional discharge measurements were made using a Price AA current meter and standard USGS procedures concurrent with the acoustic instruments at each site. Discharges measured with the acoustic instruments were compared with discharges measured with Price AA current meters and the USGS stage-discharge rating for each site. The mean discharges measured by each acoustic instrument were within 5 percent of the Price AA-based measurement and (or) discharge from the stage-discharge rating.

    A heat pipe type adsorption ice maker with two adsorbers for fishing boats is designed by using ammonia as refrigerant and compound of activated carbon-GaG12 as adsorbent. This type of heat pipe adsorber can solve the problem of incompatibility between ammonia, copper, seawater and steel. The working process of the ice maker with 8.7kg adsorbent per bed is simulated. The results show that the optimal semi-cycle time is about 9min at the evaporating temperature of -15℃, where the corresponding cooling power, specific cooling power per kilogram adsorbent SCP and coefficient of refrigerant performance COP are respectively 3.6 kW, 217 W·kg-1 and 0.404.

  16. Characterization of pigments and colors used in ancient Egyptian boat models

    International Nuclear Information System (INIS)

    The analyses of pigments originating from well dated ancient boat models found in Egyptian graves were used for characterization and for dating tasks of unknown objects. A nearly destruction free sampling technique using cotton buds was applied for sampling these valuable artifacts for a subsequent Total Reflection X-Ray Fluorescence Spectrometry (TXRF) analysis. Two relevant collections of Egyptian object of art were at our disposal, one of the Agyptisches Museum Berlin and the second of the British Museum London. Three groups of colors were studied, they originate from white, red and blue/green paints, respectively. The results of the analyses performed on micro-amounts of paints (< 1 μg) show that some artifacts were misclassified and belong to other epochs. Some others were retouched with modern colors. In general, it can be stated that results obtained by Total Reflection X-Ray Fluorescence Spectrometry may dissipate some uncertainties when applying classical archaeological dating methods

    In Patagonia, Argentina, watching dolphins, especially dusky dolphins (Lagenorhynchus obscurus), is a new tourist activity. Feeding time decreases and time to return to feeding after feeding is abandoned and time it takes a group of dolphins to feed increase in the presence of boats. Such effects on feeding behavior may exert energetic costs on dolphins and thus reduce an individual's survival and reproductive capacity or maybe associated with shifts in distribution. We sought to predict which behavioral changes modify the activity pattern of dolphins the most. We modeled behavioral sequences of dusky dolphins with Markov chains. We calculated transition probabilities from one activity to another and arranged them in a stochastic matrix model. The proportion of time dolphins dedicated to a given activity (activity budget) and the time it took a dolphin to resume that activity after it had been abandoned (recurrence time) were calculated. We used a sensitivity analysis of Markov chains to calculate the sensitivity of the time budget and the activity-resumption time to changes in behavioral transition probabilities. Feeding-time budget was most sensitive to changes in the probability of dolphins switching from traveling to feeding behavior and of maintaining feeding behavior. Thus, an increase in these probabilities would be associated with the largest reduction in the time dedicated to feeding. A reduction in the probability of changing from traveling to feeding would also be associated with the largest increases in the time it takes dolphins to resume feeding. To approach dolphins when they are traveling would not affect behavior less because presence of the boat may keep dolphins from returning to feeding. Our results may help operators of dolphin-watching vessels minimize negative effects on dolphins. PMID:22624561

    Full Text Available This narrative review summarizes findings from quantitative and qualitative research literature that has been published over the past 15 years since an initial, community-based pilot study first challenged the long-held medical belief that vigorous, upper-body exercise would lead to lymphedema in women who were at risk due to treatments for breast cancer. Dragon boat racing originated in China more than 2000 years ago and has become a popular recreational and competitive support around the world. From the advent of the world's first breast cancer survivor dragon boat team, Abreast in a Boat launched in Vancouver, British Columbia, in 1996, there are now more than 140 breast cancer survivor dragon boat teams paddling and competing in 12 different countries. The wealth of quantitative and qualitative research that has ensued since that pilot study further supports the initial hypothesis that resistance exercise, for example, dragon boat paddling, is not only safe for women recovering from conventional breast cancer therapies but also shows that dragon boating has been embraced as a complementary exercise therapy by the cancer survivors participating in this magical sport.

    Paint flaking off abandoned vessels or generated during boat repair is hazardous to human health and wildlife. In this study, a means of screening paint fragments using a field portable-X-ray fluorescence (FP-XRF) spectrometer is described. The technique is capable of delivering rapid, surficial measurements of Ba, Cu, Pb and Zn down to concentrations less than 150 μg g(-1), and Sn and Cr to concentrations of a few hundred μg g(-1). Application of the technique to fragments collected from slipways, yards, hardstandings, abandoned boats and ships undergoing maintenance throughout the EU reveal highly variable concentrations of metals among samples from the same environment or from the same region of a given boat; in many cases, variability is also evident in different areas or on different surfaces of the same fragment. Of particular concern are elevated concentrations of substances that have been restricted or banned (e.g. Sn, an indicator of organotin, and up to concentrations of 40,000 μg g(-1), and Pb up to concentrations of 200,000 μg g(-1)). Although FP-XRF can rapidly screen samples whose composition and origin are unknown and can assist in instantaneous decision making, a full risk assessment will rely on additional analyses of the precise species (including organo-forms) of the metals present.

    1995-12-20

    For improving the navigating performance of racing boats, a controllable pitch propeller mechanism has been developed, capable of responding to changes in the propeller load and of making good use of the engine performance. The effort aimed at the optimization of the propeller load to follow changes in surrounding conditions such as weather and the resultant sea roughness, the engine performance, and at the improvement of acceleration features. The blade angle is made smaller for reduced torque absorption at a low engine speed and, as the engine gathers speed, the blade angle is changed to the optimum for rapid acceleration to the maximum boat speed. The blade angle is made smaller upon deceleration. The mechanism has been designed so that it may be added on a boat rigged with a fixed pitch propeller. The design enables a propeller to properly respond to changes in the propeller load without pre-run replacement or shape-changing work. When this propeller`s performance is optimized to match the engine characteristics, there will be a propelling device with its performance further advanced. This design expands the range of engine performance in which usable one may be found. 6 refs., 6 figs., 1 tab.

    The first decade of the new millennium saw an upsurge in global financing for health. When the world took stock of progress on the Millennium Development Goals in mid-2010 the one addressing maternal health showed the least progress. Did maternal health miss the boat? In mid-2010 the Secretary-General of the United Nations launched a "Global Strategy for Women's and Children's Health", also known as the "Every Woman Every Child" initiative. Has the tide now turned in favour of maternal health? The authors try to answer this question by first examining whether maternal health really missed out with respect to increased global funding and why this may have occurred. They then assess whether the new initiative will make a difference by comparing several elements of the approach taken by HIV/AIDS activist to that of maternal health activists. They suggest that real progress requires international financing, thus pledges must become robust and reliable commitments. They conclude that the absence of an organisational structure in the current initiative means the global maternal health financing revolution will probably not happen.

  6. extrap: Software to assist the selection of extrapolation methods for moving-boat ADCP streamflow measurements

    Mueller, David S.

    2013-04-01

    Selection of the appropriate extrapolation methods for computing the discharge in the unmeasured top and bottom parts of a moving-boat acoustic Doppler current profiler (ADCP) streamflow measurement is critical to the total discharge computation. The software tool, extrap, combines normalized velocity profiles from the entire cross section and multiple transects to determine a mean profile for the measurement. The use of an exponent derived from normalized data from the entire cross section is shown to be valid for application of the power velocity distribution law in the computation of the unmeasured discharge in a cross section. Selected statistics are combined with empirically derived criteria to automatically select the appropriate extrapolation methods. A graphical user interface (GUI) provides the user tools to visually evaluate the automatically selected extrapolation methods and manually change them, as necessary. The sensitivity of the total discharge to available extrapolation methods is presented in the GUI. Use of extrap by field hydrographers has demonstrated that extrap is a more accurate and efficient method of determining the appropriate extrapolation methods compared with tools currently (2012) provided in the ADCP manufacturers' software.

    Mobile mapping systems (MMSs) are used for mapping topographic and urban features which are difficult and time consuming to measure with other instruments. The benefits of MMSs include efficient data collection and versatile usability. This paper investigates the data processing steps and quality of a boat-based mobile mapping system (BoMMS) data for generating terrain and vegetation points in a river environment. Our aim in data processing was to filter noise points, detect shorelines as well as points below water surface and conduct ground point classification. Previous studies of BoMMS have investigated elevation accuracies and usability in detection of fluvial erosion and deposition areas. The new findings concerning BoMMS data are that the improved data processing approach allows for identification of multipath reflections and shoreline delineation. We demonstrate the possibility to measure bathymetry data in shallow (0–1 m) and clear water. Furthermore, we evaluate for the first time the accuracy of the BoMMS ground points classification compared to manually classified data. We also demonstrate the spatial variations of the ground point density and assess elevation and vertical accuracies of the BoMMS data. PMID:24048340

    Earth science research must bridge the gap between the atmosphere and the ocean to foster understanding of Earth s climate and ecology. Ocean sensing is typically done with satellites, buoys, and crewed research ships. The limitations of these systems include the fact that satellites are often blocked by cloud cover, and buoys and ships have spatial coverage limitations. This paper describes a multi-robot science exploration software architecture and system called the Telesupervised Adaptive Ocean Sensor Fleet (TAOSF). TAOSF supervises and coordinates a group of robotic boats, the OASIS platforms, to enable in-situ study of phenomena in the ocean/atmosphere interface, as well as on the ocean surface and sub-surface. The OASIS platforms are extended deployment autonomous ocean surface vehicles, whose development is funded separately by the National Oceanic and Atmospheric Administration (NOAA). TAOSF allows a human operator to effectively supervise and coordinate multiple robotic assets using a sliding autonomy control architecture, where the operating mode of the vessels ranges from autonomous control to teleoperated human control. TAOSF increases data-gathering effectiveness and science return while reducing demands on scientists for robotic asset tasking, control, and monitoring. The first field application chosen for TAOSF is the characterization of Harmful Algal Blooms (HABs). We discuss the overall TAOSF architecture, describe field tests conducted under controlled conditions using rhodamine dye as a HAB simulant, present initial results from these tests, and outline the next steps in the development of TAOSF.

    A literature search and survey of Virginia, USA, campgrounds with RV pump-out stations were used to determine whether boat holding-tank deodorant chemicals would have deleterious effects on marina septic systems or package treatment plants. Laboratory studies reported in the literature indicate that these chemical additives could affect septic system function in three ways: (1) active ingredients in the additives can impair sewage degradation in septic tanks, causing sludge buildup and overflow of solids into the drainfield, (2) additive chemicals might enter the drainfield and, in high enough concentrations, reduce the drainfield's ability to degrade waste, or (3) toxic additive chemicals might migrate from the drainfield to ground or surface water. Laboratory studies also show that some ingredients added to holding tanks interfere with functioning of activated sludge treatment process. Experience in the field and in other laboratory studies suggests that factors such as dilution of treated waste with untreated waste and the characteristics of the sewage to be treated can reduce the possibility of damage to septic and activated sludge systems. The campground owners surveyed indicated that they have few problems with their septic systems in spite of the presence of chemical additives in the RV waste. However, most of them practice good septic system maintenance and have devised other means of ensuring that their systems function efficiently. In addition, the survey indicates that most Virginia campgrounds get only seasonal use (as would marinas in Virginia), allowing their systems to recover between peak seasons.

    Water level forecasting using recorded time series can provide a local modelling capability to facilitate local proactive management practices. To this end, hourly sea water level time series are investigated. The records collected at the Hillarys Boat Harbour, Western Australia, are investigated over the period of 2000 and 2002. Two modelling techniques are employed: low-dimensional dynamic model, known as the deterministic chaos theory, and genetic programming, GP. The phase space, which describes the evolution of the behaviour of a nonlinear system in time, was reconstructed using the delay-embedding theorem suggested by Takens. The presence of chaotic signals in the data was identified by the phase space reconstruction and correlation dimension methods, and also the predictability into the future was calculated by the largest Lyapunov exponent to be 437 h or 18 days into the future. The intercomparison of results of the local prediction and GP models shows that for this site-specific dataset, the local prediction model has a slight edge over GP. However, rather than recommending one technique over another, the paper promotes a pluralistic modelling culture, whereby different techniques should be tested to gain a specific insight from each of the models. This would enable a consensus to be drawn from a set of results rather than ignoring the individual insights provided by each model.

    Full Text Available Although scalping is a recurrentaccident innorthern Brazil, there are still few studies on the subject. The aim of the present work was to report the occupational therapy procedure on the minimization of the occupational performance impairment of two riverside children that were victims of scalping by unprotected motor boat shaft, through the evaluation of occupational performance and exposure of the intervention performed. This is a case study with two scalped riverside girls hospitalized between April and June, 2013. The application of evaluation protocols verified changes in the areas of occupational performance, where activities of daily living (ADL such as dependence for bathing and ambulationare inserted; changesin the performance context, verified in the anxiety to be discharged from hospital; and changesin the performance component, with decreased self-esteem because of the change on their self-image. Reassessment after intervention showed improvement in the performance of ADL and self-image perceptionof both patients. Thereby it is believed that the development of the research allowed the contact with a theme that is so typical in the Braziliannorth region, stressing the importance of Occupational Therapy assistance, providing greater independence in the performance of ADL that are meaningful to each child.

  12. Don't rock the boat: how antiphase crew coordination affects rowing.

    Directory of Open Access Journals (Sweden)

    Anouk J de Brouwer

    Full Text Available It is generally accepted that crew rowing requires perfect synchronization between the movements of the rowers. However, a long-standing and somewhat counterintuitive idea is that out-of-phase crew rowing might have benefits over in-phase (i.e., synchronous rowing. In synchronous rowing, 5 to 6% of the power produced by the rower(s is lost to velocity fluctuations of the shell within each rowing cycle. Theoretically, a possible way for crews to increase average boat velocity is to reduce these fluctuations by rowing in antiphase coordination, a strategy in which rowers perfectly alternate their movements. On the other hand, the framework of coordination dynamics explicates that antiphase coordination is less stable than in-phase coordination, which may impede performance gains. Therefore, we compared antiphase to in-phase crew rowing performance in an ergometer experiment. Nine pairs of rowers performed a two-minute maximum effort in-phase and antiphase trial at 36 strokes min(-1 on two coupled free-floating ergometers that allowed for power losses to velocity fluctuations. Rower and ergometer kinetics and kinematics were measured during the trials. All nine pairs easily acquired antiphase rowing during the warm-up, while one pair's coordination briefly switched to in-phase during the maximum effort trial. Although antiphase interpersonal coordination was indeed less accurate and more variable, power production was not negatively affected. Importantly, in antiphase rowing the decreased power loss to velocity fluctuations resulted in more useful power being transferred to the ergometer flywheels. These results imply that antiphase rowing may indeed improve performance, even without any experience with antiphase technique. Furthermore, it demonstrates that although perfectly synchronous coordination may be the most stable, it is not necessarily equated with the most efficient or optimal performance.

    2015-01-01

    Through a literature study and logic analysis,the paper investigates the origin of dragon boating. The research shows that the relationship between the dragon boat and the bird has an earlier origin than that between the boat and the dragon,and that the predecessor of the dragon boat is the bird-dragon boat,which functions as a ritual artifact,a magic talisman and an entertainment tool. We hypothesize that boating on the Double Fifth Festival came into existence in the Eastern Han Dynasty during commemorations of Qu Yuan,with the location being in Miluo in Chu. This boating is earlier than the Dragon Boating. However,the worship of Qu Yuan and the customs of the Double Fifth Festival were only the ex-ternal environment of the boating. The internal condition was localist competition. A real dragon boat began to be built in the East Han Dynasty,but was only reserved for god riding. In reality people still used the bird-dragon boat. The use of the real dragon boat began in the early Tang Dynasty,mainly on the Double Fifth Festival. The reason for the use of the dragon boat lies in the dragon’s significant status and its symbolic meaning. The legend of commemoration of Qu Yuan is earlier than that of commemoration of Wu Zixu,Gou Jian and Cao E.%运用文献资料法、逻辑分析法对端午龙舟竞渡的起源进行考证。龙舟与鸟的关系比龙舟与龙的关系更早,龙舟的前身是鸟龙舟,集祭祀神器、巫术法器和娱乐工具等功能为一体;提出了“东汉时期端午纪念屈原的过程中产生了竞渡”的假说,起源地点在荆楚汨罗;端午竞渡先于端午龙舟竞渡;祭祀屈原、仲夏端午习俗都是竞渡产生的外部环境,内部原因实为地方主义竞争;确切的龙舟造型始于东汉,仅作为神仙坐骑,现实竞渡中仍使用鸟龙舟;确切的龙舟用于竞渡始于唐代初期,举办时间主要在端午节;竞渡用龙舟的理由是因为龙的显著地位及其象

    This paper describes estimation of performance of a high-speed boat by using the Rankine source method. An orthogonal coordinate system is considered, which uses the center of a hull as the zero point, and is made dimensionless by using the hull length. The catamaran boat or the single hull boat being the subject of the discussion is supposed to have a transom stern, and to be sailing at a constant speed in the -X direction. A governing equation and a border condition were formulated using disturbance speed potential and X-direction speed differentiation. An inverse specular image was employed as a specular image system upon considering attitude change in the high-speed boat. As to the division of hull surface, the portions protruded above the static water surface were cut off from among the panel data of boat CAD. Considering a high speed condition in which the water surface is completely separated at the transom section, the water level at the transom section was supposed to be at the same height as at the rear end of the hull. Blow-out intensity at the water surface was derived in such a way that a CAD panel of the rear end of the hull is searched and wave height agrees with the height of the transom in the Z direction. A resistance curve may be obtained easily by using a personal computer. 4 refs., 8 figs.

    This study focused in turn on detailed data of buildings and boats damage caused by the 2011 tsunami in order to understand its main causes and provide damage probability estimates. Tsunami-induced building damage data was collected from field surveys, and includes inundation depth, building material, number of stories and occupancy type for more than 80,000 buildings. Numerical simulations with high resolution bathymetry and topography data were conducted to obtain characteristic tsunami measures such as flow velocity. These data were analyzed using advanced statistical methods, ordinal regression analysis to create not only empirical 2D tsunami fragility curves, but also 3D tsunami fragility surfaces for the first time. The effect of floating debris was also considered, by using a binary indicator of debris impact based on the proximity of a structure from a debris source (i.e. washed away building). Both the 2D and 3D fragility analyses provided results for each different building damage level, and different topography. While 2D fragility curves provide easily interpretable results relating tsunami flow depth to damage probability for different damage levels, 3D fragility surfaces allow for several influential tsunami parameters to be taken into account thus reduce uncertainty in the probability estimations. More than 20,000 damaged boats were used in the analysis similar to the one carried out on the buildings. Detailed data for each boat comprises information on the damage ratio (paid value over insured value), tonnage, engine type, material type and damage classification. The 2D and 3D fragility analyses were developed using representative tsunami heights for each port obtained from field surveys and flow velocities obtained from the aforementioned simulations. The results are currently being adapted for practical disaster mitigation. They are being integrated with the probabilistic tsunami hazard analysis, in order to create offshore and onshore

    Santee Cooper is planning to construct an electricity generating station in southeastern Florence County near the Kingsburg community. As part of this project, a water-intake structure will be constructed on the Pee Dee River near the Bostick Boat Landing, which is located east of the intersection of State secondary roads S-21-57 and S-21-66. Velocity, bathymetric, and dissolved oxygen data are needed to help determine the location for the water-intake structure. The U.S. Geological Survey (USGS), in cooperation with Santee Cooper, collected these data at three different flow regimes during the period of May through August 2007. Data were collected along 15 transects located at 50-foot intervals starting 400 feet upstream from the boat landing and continuing to 300 feet downstream from the boat landing. All data were geographically referenced using a differentially corrected global positioning system (GPS).

    2011-01-01

    This paper provides the information on the optimum conditions of the treatment process of the boat pressure washing wastewater (BPWW) by the combination of the ozonation and electrochemical (EC) methods developed on the laboratory and pilot plant scale. The initial effluent was highly enriched in heavy metals and elevated levels of organic contaminants. The concentrations of V, Cr, Fe, Cu, Zn, TOC, and COD exceeded the upper permissible limits of 22, 20, 6, 112, 17, 4, and 2 times, respectively. The main mechanisms of the organic matter destruction were the ozone oxidation and the indirect oxidation with chlorine/hypochlorite formed by the anodic oxidation of chloride already present in the wastewater. The heavy metal removal was forced by the coagulation/flocculation using Fe(2+), Fe(3+), and Al(3+) ions released into the treated solution by electrochemical corrosion of the sacrificial stainless steel and aluminum electrodes. At the optimum conditions obtained with the pilot plant, the removal efficiencies of the parameters V, Cr, Fe, Ni, Cu, Zn, Pb, TOC, and COD were 100.00 %, 99.35 %, 99.51 %, 87.31 %, 99.83 %, 99.65 %, 100.00 %, 88.46 %, and 76.28 %, respectively. All the parameters in the final effluent were in agreement with regulated values. The advantages of this system compared to its physico-chemical counterparts are as follows: (1) no need for the external addition of flocculating agents since they are electrochemically generated inside the treatment tank; (2) minimal pH changes during the treatment process not requiring pH adjustment by acids/basis; (3) a significantly lower amount of sludge since only Fe and Al ions were released in the solution; (4) flocs formed by the electrocoagulation can be easily separated by the filtration due to their higher stability, lower content of the bound water and larger surface compared to chemical flocs; (5) the final EC effluent is clear, colourless and odourless, containing the less total dissolved solids and

    Sarah-Kate Millar

    2015-11-01

    Full Text Available Aim: An effective catch in sculling is a critical determinant of boat velocity. This study used rowers’ performance-based judgments to compare three measures of catch slip efficiency. Two questions were addressed: (1 would rower-judged Yes strokes be faster than No strokes? and (2 which method of quantifying catch slip best reflected these judgements? Methods: Eight single scullers performed two 10-min blocks of sub maximal on-water rowing at 20 strokes per minute. Every 30 s, rowers reported either Yes or No about the quality of their stroke at the catch. Results: It was found that Yes strokes identified by rowers had, on average, a moderate effect advantage over No strokes with a standardised effect size of 0.43. In addition, a quicker time to positive acceleration best reflected the change in performance; where the standardised mean difference score of 0.57 for time to positive acceleration was larger than the scores of 0.47 for time to PowerLine force, and 0.35 for time to 30% peak pin force catch slip measures. For all eight rowers, Yes strokes corresponded to time to positive acceleration occurring earlier than No strokes. Conclusion: Rower judgements about successful strokes was linked to achieving a quicker time to positive acceleration, and may be of the most value in achieving a higher average boat velocity.

    Fishing is a major local industry in Malaysia, particularly in rural areas. However, the rapidly increasing price of fuel is seriously affecting the industry's viability. At present, outboard petrol engines are the preferred choice for use in small-scale fishing boats because they deliver the advantages of high speed and low weight, they are easy to install, and they use minimal space. Petrol outboard engines are known to consume a greater amount of fuel than inboard diesel engines, but installing diesel engines with conventional submerged propellers in existing small-scale fishing boats is not economically viable because major hullform modifications and extra expenditure are required to achieve this. This study describes a proposal to enable reductions in fuel consumption by introducing the combined use of a diesel engine and surface-piercing propeller (SPP). An analysis of fuel consumption reduction is presented, together with an economic feasibility study. Resulting data reveal that the use of the proposed modifications would save 23.31 liters of fuel per trip (40.75 %) compared to outboard motors, equaling annual savings of RM 3962 per year.

    2010-03-15

    Leachates of anti-fouling paints for use on ships and leisure boats are examined for their ecotoxicological potential. Paint leachates were produced in both 7 per mille artificial (ASW) and natural seawater (NSW) and tested on three organisms, the bacterium Vibrio fischeri, the macroalga Ceramium tenuicorne, and the crustacean Nitocra spinipes. Generally, leaching in ASW produced a more toxic leachate and was up to 12 times more toxic to the organisms than was the corresponding NSW leachate. The toxicity could be explained by elevated concentrations of Cu and Zn in the ASW leachates. Of the NSW leachates, those from the ship paints were more toxic than those from leisure boat paints. The most toxic paint was the biocide-free leisure boat paint Micron Eco. This implies that substances other than added active agents (biocides) were responsible for the observed toxicity, which would not have been discovered without the use of biological tests. - Leachate from a biocide-free anti-fouling paint for leisure boat use was more toxic than leachates from ship paints.

  5. On biogeochemistry and water quality of river canals in Northern France subject to daily sediment resuspension due to intense boating activities

    International Nuclear Information System (INIS)

    In Northern France, channelized rivers facilitate greatly the waterway transport that should still increase in the coming years to replace as much as possible the road traffic, considered as a heavier source of pollution. These rivers are now subjected to the good potential status objectives required by the Water Framework Directive. The impact of the recurrent resuspension by the current boat traffic of polluted sediments (due to strong historical pollution) on the water quality is the main concern of this work. Our study reveals that the navigation seems to play a limited role on the enrichment of the water columns by dissolved metals and phosphorus, as well as on the oxygenation of surface waters. Conversely, the cycling of the phytoplankton over the year appears to partly control the physico-chemical and chemical evolutions of the overlying waters. - Highlights: • In river canals boating results in the daily resuspension of polluted sediments. • Chemical indexes indicate that metals should be well trapped in the sediments. • Polluted sediments in Cd and Pb may only slightly enrich the river waters. • Daily boating activity results in the scavenging of dissolved phosphorus. • Phytoplanktonic biomass and seasonal effects partly control the water quality. - Polluted sediments resuspension in river canals by daily boat traffic seems to play a limited role on the enrichment of the water columns by dissolved metals and phosphorus

    Full Text Available The dramatic range expansion of the dengue vector Aedes aegypti is associated with various anthropogenic transport activities, but little is known about the underlying mechanisms driving this geographic expansion. We longitudinally characterized infestation of different vehicle types (cars, boats, etc. to estimate the frequency and intensity of mosquito introductions into novel locations (propagule pressure.Exhaustive adult and immature Ae. aegypti collections were performed on six different vehicle types at five ports and two bus/ taxi departure points in the Amazonian city of Iquitos, Peru during 2013. Aquatic vehicles included 32 large and 33 medium-sized barges, 53 water taxis, and 41 speed boats. Terrestrial vehicles sampled included 40 buses and 30 taxis traveling on the only highway in the region. Ae. aegypti adult infestation rates and immature indices were analyzed by vehicle type, location within vehicles, and sampling date.Large barges (71.9% infested and medium barges (39.4% infested accounted for most of the infestations. Notably, buses had an overall infestation rate of 12.5%. On large barges, the greatest number of Ae. aegypti adults were found in October, whereas most immatures were found in February followed by October. The vast majority of larvae (85.9% and pupae (76.7% collected in large barges were produced in puddles formed in cargo holds.Because larges barges provide suitable mosquito habitats (due to dark, damp cargo storage spaces and ample oviposition sites, we conclude that they likely serve as significant contributors to mosquitoes' propagule pressure across long distances throughout the Peruvian Amazon. This information can help anticipate vector population mixing and future range expansions of dengue and other viruses transmitted by Ae. aegypti.

    Japan has been free from rabies since 1958 and various preventive measures are in place protecting the country from the introduction of the disease. Historical reviews indicate that the illegal landing of dogs from Russian fishing boats in the ports of Hokkaido occurred frequently especially in the early 2000s and this could potentially be a source of introduction of rabies into Japan. The method of scenario tree modelling was used and the following entry and exposure pathway was considered the most likely route of rabies entry: a rabies-infected dog arriving on a Russian fishing boat lands in a port of Hokkaido in Japan, it becomes infectious, contacts and infects a susceptible domestic animal (companion dog, stray dog or wildlife). Input parameter values were based on surveys of Russian fishermen, expert opinion and scientific data from the literature. At present (2006-2015), the probability of the introduction of rabies as a result of one Russian fishing boat arriving at a port of Hokkaido is 8.33×10(-10) (90% Prediction Interval (PI): 7.15×10(-11)-5.34×10(-9)), while this probability would have been 7.70×10(-9) (90% PI: 6.40×10(-10)-4.81×10(-8)) in the past (1998-2005). Under the current situation (average annual number of boat arrivals is 1106), rabies would enter Japan every 1,084,849 (90% PI: 169,215-20,188,348) years, while the disease would have been introduced every 18,309 (90% PI: 2929-220,048) years in the past (average annual number of boat arrivals is 7092). The risk of rabies introduction has decreased 59 fold due to both the effective control of the issue of illegal landing of dogs and the decline in the number of Russian boat arrivals. Control efforts include education of Russian fishermen, establishment of warning signs, daily patrols and regular port surveillance of potential dog landing activity. Furthermore, scenario analysis revealed that the policy of mandatory domestic dog vaccination does not contribute effectively to Japan's rabies

    The important demand at the European level for electrical boats shows the great interest for such a technology. We can expect an important growth of electric boats production. Thus, two means could be used to provide a maximum of comfort, reliability, silence, absence of pollution and respect of the environment: photovoltaics and fuel cells. The purpose of the present project is to explore the second solution. A small boat 'Hydroxy100' has been designed as first prototype in the field of a diploma work. A larger boat, 'Hydroxy300', with the use of a 300-watt PEFC fuel cell was realised and successfully presented at the international fuel cells meeting in Lucerne (June 99) and other occasions. The subject is also an excellent didactical application for the electrical degree students of our technical university. (author)

    Su Shi’s life is a wandering life ,and he always displaced in constant banishment ,so the boat has become an indispensable means of transport in his life ,naturally it is often written in his poetry .Overall ,in Su Shi’s poetry ,the boat image approximately displays three kinds of beauty .The first is the beautiful scene of boats traveling on the clear lake .Boats become a part of the picture which shows a static and dynamic as well as virtual and realistic beauty .The sec-ond beautiful scene is boats traveling in the heart .Su Shi uses boats to express four kinds of emotion such as subtle spiri-tual world ,the sadness of leaving ,the state of detachment and wandering melancholy .The third beautiful scene is Boats traveling in the history river .The image of bats in Su Shi’s poetry not only has many flash ideas in history but also dis-plays the social customs in his time ,which has an important status in similar poetry creation for he inherits past traditions and breaks new grounds for the future .These three beautiful scenes have intertwined and constituted a colorful boats world in Su Shi’s poetry .%苏轼的一生是漂泊的一生,始终在不断的迁谪中流离,舟船就成为了他一生中离不开的交通工具,自然也成了他诗词中经常书写的对象。总的来看,在苏轼的词作中,舟船意象大致呈现出三类美:一是舟行碧波上的图画美,这类图画美是以舟船入景,把舟船作为欣赏的一部分,主要动静和虚实之分。二是舟行内心世界里的情感美,在苏轼的词中借舟船抒发了微妙的心灵世界、离别的伤感、超脱的境界、漂泊的愁绪四种情感。三是舟行于历史长河中的文化美,苏词中的舟船意象不仅带有传统文化中诸多闪光的思想理念,也表现了苏轼所处时代的社会风俗,并在同类诗词创作的历史传统中也具有承前启后的重要地位。这三种美相互交织构成苏轼词里色彩斑斓的舟船世界。

    The role of twist-boat conformers of cyclohexanones in hydride reductions was explored. The hydride reductions of a cis-2,6-disubstituted N-acylpiperidone, an N-acyltropinone, and tert-butylcyclohexanone by lithium aluminum hydride and by a bulky borohydride reagent were investigated computationally and compared to experiment. Our results indicate that in certain cases, factors such as substrate conformation, nucleophile bulkiness, and remote steric features can affect stereoselectivity in ways that are difficult to predict by the general Felkin-Anh model. In particular, we have calculated that a twist-boat conformation is relevant to the reactivity and facial selectivity of hydride reduction of cis-2,6-disubstituted N-acylpiperidones with a small hydride reagent (LiAlH4) but not with a bulky hydride (lithium triisopropylborohydride).

    This work examines alternative fuels in pleasure boat engines, their effect on engine performance as well as chemical and ecotoxicological characterisation of exhaust emissions to water and air. Three marine diesel engines and one outboard two stroke petrol engine were tested with standard fuels and 'green' fuels, that is for the diesel engine s; GTL (synthetic diesel) and biodiesel (rapeseed methyl ester, RME) and for the outboard engine; alkylate petrol and E85 (ethanol fuel). The outboard engine was converted for the ethanol fuel. GTL generated less particles, hydrocarbons, carbon monoxide and nitrogen oxides than standard diesel. RME generated far less particles and hydrocarbons but slightly more nitrogen oxides. Cooling water from diesel engine s was toxic to zebra fish and crustaeans. GTL and RME generated cooling water that was less toxic to zebra fish compared to standard diesel. One litre of diesel produced 10-20 mg PAH, polyaromatic hydrocarbons, to the cooling water. The traditional two stroke outboard engines are by far the dominating source of emissions from the pleasure crafts. Standard petrol generates high concentrations of harmful pollutants such as benzene, PAHs and formaldehyde. One litre of standard petrol produced 2.3 g PAH in this survey. Alkylate petrol and ethanol fuel, E85, generated far less emissions. The emissions of PAHs from the Swedish pleasure boats annually are 50 tons or more in our estimations. Exhaust from two stroke outboard engines mixed in water is toxic to bacteria, algae and crustaceans. Standard petrol generated the most water toxic to bacteria and crustaceans. Alkylate petrol generated less toxic water to bacteria and crustaceans. For algae there was little difference between the fuels. Despite the fact that most of the fuel in the pleasure crafts are used in open sea, the effects of the emissions can be bigger in lakes and rivers. Traditional two stroke engines are used in lakes that are used for producing

    The project has focused on spreading knowledge about CO2 refrigeration technology in Norwegian industry and to make Norwegian industry able to supply commercial plant with CO2 as refrigerant, especially adapted to the conditions on fishing boats. Through the project it has been built and installed an RSW CO2 plant in a fishing boat. This is the first RSW CO2 system for a boat, built in Norway. It has been tested under realistic hunting conditions and have shown good results. Approximately 900 tonnes of capelin has been chilled, and even under poor conditions such as strong weather conditions has worked without operational problems. The project and the technology has been presented to refrigation industry, and it was a great interest in the plant solution. The project is demonstrated and tested how a RSW CO2 systems can be developed for use aboard the boat. The technology has been tested and will be in regular commercial operation forward. For fisheries, this means that there is now an environmentally friendly alternative for cooling fish on board the boat. If more boats are installing such facilities ahead, it will result in lower environmental impact from the Norwegian fishing fleet.(eb)

    Hydroacoustic methods are widely employed by fish scientists for assessing fish stocks. The method most often used is echosounding, beaming vertically. Nowadays the multibeam sonar, and therefore the 3-D presentation of fish schools, has yielded better knowledge of school morphology. Using the data collected simultaneously by both sonar and echosounding in a lake, we have identified boat-induced behavioural changes in small pelagic fish schools. Using high resolution sonar data, we showed tha...

    Full Text Available The Bajau Laut (Samal people, also known as pala’u, is among theBajau ethnic tribes in the east coast of Sabah who are still practicing the sea nomads lifestyle. They are synonym with the lepa-lepa, a boat in which they live on the sea. In the effort to preserve this heritage and culture, the Ministry of Culture, Arts and Tourism of Sabah has gazette the “Lepa-Lepa Regatta” in the Sabah tourism calendar. Other than Lepa-Lepa, the Bajau Laut community actually treasures another sampan design that is unique only to the tribe. It is the winged sampan called bogoo that is used for fishing. Nevertheless, this unique heritage and culture has never been exposed to the public by any scholar studying this subject. This article is written for the purpose of documenting the sampan as one of the heritage and culture of the Bajau Laut community in order to avoid the disappearance of this culture tothe development. This writing is based on the field work done by theauthor regarding the tradition of Bajau Laut community in the east coast of Sabah in Mac 2007.

    This was a retrospective review and descriptive analysis of the findings from the medical screening examinations conducted on the illegal migrants from Fujian Province of China (n = 589) who arrived on four boats on the West Coast of Canada between June 14 and September 9, 1999. The Canadian Navy conducted a screening medical exam of the illegal migrants, with Health Canada and Citizenship and Immigration Canada providing suggestions on the format of the exam. The illegal Chinese migrants were predominantly young, male adults. The most prevalent medical conditions detected were dermatological (55.2%), dental problems (25%), trauma (9.2%), urogenital (7.6%), and head/neck (6.6%). Recently induced trauma was more prevalent among females (20.5%) than males (6.5%). One case of community-acquired pneumonia was identified and later diagnosed as active pulmonary tuberculosis. Physicians dealing with illegal migrants should look for unusual physical findings and have a higher clinical suspicion regarding infectious diseases (tuberculosis, scabies) and abuse. Future encounters with illegal migrants should include standardized immigration screening exams, with adequate history taking and follow-up. PMID:19813289

  20. Managerial decisions as experiments: an opportunity to determine the ecological impact of boat-generated waves on macrobenthic infauna

    Bishop, M. J.; Chapman, M. G.

    2004-12-01

    A previous correlative study showed that assemblages of macrobenthic infauna and abundances of common taxa on intertidal mudflats differed between a no-wash zone, where ferries had to minimize production of wash, and places where the production of wash was unrestricted (wash zone). This suggested that boat-generated waves (wash) are important in determining the structure of these assemblages. Causality between wash and the observed patterns could not, however, be unambiguously established, due to the absence of 'before' data. Here, a managerial decision to stop ferry services on the upper Parramatta River, Sydney, Australia during the 2000 Olympics was used as the basis for a manipulative experiment to examine the effects of changes in the amount of wash on these fauna. It was hypothesized that if wash is important in structuring infaunal assemblages, assemblages in the wash zone would become more similar to those of the no-wash zone following removal of the disturbing force, i.e. the ferry service. Similarly, if the smaller abundances of capitellids, nereids and spionids in the wash zone are caused by this disturbance, abundances should increase in the wash zone during the stoppage and decrease following the return of services. As hypothesized, assemblages within the wash zone became more similar to those of the no-wash zone following the temporary removal of the ferry services. Following the return of ferries, assemblages changed back towards (although not reaching) their previous state. Abundances of the polychaete families Nereididae, Capitellidae and Spionidae also increased at some sites during the cessation, although this pattern was not found in all sites and there was no general response to the cessation of wash as had been predicted. These results indicate that wash is important in structuring assemblages of macrobenthic infauna, although responses of individual taxa are more idiosyncratic. More importantly, they show that manipulations, resulting from

The parent-subsidiary wind sailing boat, which add a sub-ship on the basis of each side of a mother-boat and which is equivalent to the molded breadth B, improve the righting moment, capacity of resisting to external torque and stability of ship. So, larger sails can be added in this kind of ship. This article demonstrates the advantages of the parent-subsidiary wind sailing by rationally allocating the appropriate fluid spacing between the mother ship and sub-ship, u-sing analysis method which simulating to some points on the maximum cross-section of the parent-subsidiary wind sailing boat. We can say that the parent-subsidiary wind sailing boat has largely improved ancient and modern sailboat. Therefore, the method can greatly save energy and achieve very good environment protection. So, economic benefits and social benefits of this method is very obvious.

    The U.S. Geological Survey (USGS), in cooperation with the National Monitoring Network for U.S. Coastal Waters and Tributaries, launched a pilot project in 2010 to determine the value of integrated synoptic surveys of rivermouths using autonomous underwater vehicle technology in response to a call for rivermouth research, which includes study domains that envelop both the fluvial and lacustrine boundaries of the rivermouth mixing zone. The pilot project was implemented at two Lake Michigan rivermouths with largely different scales, hydrodynamics, and settings, but employing primarily the same survey techniques and methods. The Milwaukee River Estuary Area of Concern (AOC) survey included measurements in the lower 2 to 3 miles of the Milwaukee, Menomonee, and Kinnickinnic Rivers and inner and outer Milwaukee Harbor. This estuary is situated in downtown Milwaukee, Wisconsin, and is the most populated basin that flows directly into Lake Michigan. In contrast, the Manitowoc rivermouth has a relatively small harbor separating the rivermouth from Lake Michigan, and the Manitowoc River Watershed is primarily agricultural. Both the Milwaukee and Manitowoc rivermouths are unregulated and allow free exchange of water with Lake Michigan. This pilot study of the Milwaukee River Estuary and Manitowoc rivermouth using an autonomous underwater vehicle (AUV) paired with a manned survey boat resulted in high spatial and temporal resolution datasets of basic water-quality parameter distributions and hydrodynamics. The AUV performed well in these environments and was found primarily well-suited for harbor and nearshore surveys of three-dimensional water-quality distributions. Both case studies revealed that the use of a manned boat equipped with an acoustic Doppler current profiler (ADCP) and multiparameter sonde (and an optional flow-through water-quality sampling system) was the best option for riverine surveys. To ensure that the most accurate and highest resolution velocity data

    Full Text Available Anthropogenic (man-made noise has been shown to have a negative impact on the behaviour and physiology of a range of terrestrial and aquatic animals. However, direct assessments of fitness consequences are rare. Here we examine the effect of additional noise on early life stages in the model cichlid fish, Neolamprologus pulcher. Many fishes use and produce sounds, they are crucial elements of aquatic ecosystems, and there is mounting evidence that they are vulnerable to anthropogenic noise; adult N. pulcher have recently been shown to change key behaviours during playback of motor boat noise. Using a split-brood design to eliminate potential genetic effects, we exposed half of the eggs and fry from each clutch to four weeks of playbacks of noise originally recorded from small motor boats with the other half acting as a control (receiving no noise playback. There was no significant effect of additional noise on hatching success or fry survival, length or weight at the end of the exposure period. Although care should be taken not to generalize these findings on a single species from a laboratory study, our data suggest that moderate noise increases do not necessarily have direct negative impacts on early-life survival and growth. Further studies on a range of species in natural conditions are urgently needed to inform conservation efforts and policy decisions about the consequences of anthropogenic noise.

    2015-01-01

    Aquatic invasive species are often transported between water bodies on boats or boat trailers, thus they are considered one of the primary vectors for new introductions of invasive species to a water body. This data set contains geographic positioning system locational data for boater access points, use data (i.e. recreational, fishing), water quality measurements (e.g. calcium concentrations, pH), risk assessment data, and other physical attributes (i.e. size, elevation) where available within the Columbia and Snake Rivers and throughout the Columbia River Basin. This work builds on an earlier body of work by Wells et al. 2011, Prioritizing Zebra and Quagga Mussel Monitoring in the Columbia River Basin (PDF link below), which provided much of the initial water quality, use information, and risk assessment data (categorical values for the risk of introduction and the risk of establishment). Updated information has been added by collecting additional data on use of water bodies, as well as combined categorical ranking methodology for identifying water bodies that may be high risk for both introduction and establishment of zebra and quagga mussels. This data is also related to a regional effort to contribute to the coordination of monitoring efforts for early detection of zebra and quagga mussels in the context of risk assessment data (CRBAIS weblink below). Data sets provided here include a service definition file, provided with a few reference layers within the region for viewing and an online map ( http://arcg.is/1LrNmBj) with some query options, a GIS shapefile (Child Item), and a tabular data set (csv file; Child Item).

    戴彩索、佩香包是我国端午节的重要习俗之一。端午丝帛佩饰的发展演变经历了材料和造型从简单到复杂,功能和用法从单一到复合的过程。汉代出现的彩索是最早的端午饰品,也是其他佩饰的源头;唐宋时端午饰品种类丰富,造型、材料和佩戴方式多样化,出现了簪戴于头的钗符、艾虎和艾花等;明清承袭前代而有创新,产生了装有药料的雄黄荷包、五丝囊等;现代香包兼融传统端午饰品和日常香囊而更具装饰性。%Wearing colorful thread and carrying sachet is an important custom of dragon boat festival. Dragon boat festival silk accessory experienced a simple-to-complex transformation in materials and design, and single-to-compound change in function and usage. Colorful thread, the earliest dragon boat festival ornament, is the source of other ornaments. In the Tang and Song Dynasties, the ornaments are more rich and diverse in material, style and wearing mode (especially represented in the headwear such as Chaifu, Mugwort tiger and Mugwort flower). In the Ming and Qing Dynasties, the Realgar bags and colorful bags containing drug material appeared. Modern dragon festival sachets have more decorative property integrating both the traditional dragon boat ornaments and daily spices bags.

  4. Episodic Disturbance from Boat Anchoring Is a Major Contributor to, but Does Not Alter the Trajectory of, Long-Term Coral Reef Decline.

    Directory of Open Access Journals (Sweden)

    Graham E Forrester

    Full Text Available Isolating the relative effects of episodic disturbances and chronic stressors on long-term community change is challenging. We assessed the impact of an episodic disturbance associated with human visitation (boat anchoring relative to other drivers of long-term change on coral reefs. A one-time anchoring event at Crab Cove, British Virgin Islands, in 2004 caused rapid losses of coral and reef structural complexity that were equal to the cumulative decline over 23 years observed at an adjacent site. The abundance of small site-attached reef fishes dropped by approximately one quarter after the anchoring event, but this drop was not immediate and only fully apparent two years after the anchoring event. There was no obvious recovery from the impact, and no evidence that this episodic impact accelerated or retarded subsequent declines from other causes. This apparent lack of synergism between the effect of this episodic human impact and other chronic stressors is consistent with the few other long-term studies of episodic impacts, and suggests that action to mitigate anchor damage should yield predictable benefits.

  5. What Makes a Literary Translation Obsolete? Contrastive analysis of culture-specific expressions in two translations of Jerome K. Jerome’s Three Men in a Boat

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available It rarely happens that a literary work is translated twice into Slovenian. The elements in a text that tie it most strongly to its temporal, social and cultural background are culture-specific concepts. They would be the first to sound archaic, even incomprehensible to the contemporary reader. Based on the contrastive analysis of the two Slovenian translations of Jerome K. Jerome’s travelogue, Three Men in a Boat, the study tries to clarify what stimulated the second translation thirty-five years after the first one. The first translation by Avgust Petrišič was published in 1952, the second by Maja Kraigher thirty-five years later. In view of the fact that languages undergo constant changes, did the translations of culture-specific concepts in the first translation become too archaic, even incomprehensible? Or did the strategies and norms for dealing with culturespecific concepts at the time of the first translation become dated? The results may help to explain why some translations become obsolete and what motivates the appearance of new ones.

  6. Impact of using fishing boat fuel with high poly aromatic content on the emission of polycyclic aromatic hydrocarbons from the diesel engine

    Science.gov (United States)

    Lin, Yuan-Chung; Lee, Wen-Jhy; Li, Hsing-Wang; Chen, Chung-Ban; Fang, Guor-Cheng; Tsai, Perng-Jy

    Because of the fishery subsidy policy, the fishing boat fuel oil (FBFO) exemption from commodity taxes, business taxes and air pollution control fees, resulted in the price of FBFO was ˜50% lower than premium diesel fuel (PDF) in Taiwan. It is estimated that ˜650,000 kL FBFO was illegally used by traveling diesel-vehicles (TDVs) with a heavy-duty diesel engine (HDDE), which accounted for ˜16.3% of the total diesel fuel consumed by TDVs. In this study, sulfur, poly aromatic and total-aromatic contents in both FBFO and PDF were measured and compared. Exhaust emissions of polycyclic aromatic hydrocarbons (PAHs) and their carcinogenic potencies (BaP eq) from a HDDE under transient cycle testing for both FBFO and PDF were compared and discussed. Finally, the impact caused by the illegal use of FBFO on the air quality was examined. Results show that the mean sulfur-, poly aromatic and aromatic-contents in FBFO were 43.0, 3.89 and 1.04 times higher than that of PDF, respectively. Emission factors of total-PAHs and total-BaP eq obtained by utilizing FBFO were 51.5 and 0.235 mg L -1-Fuel, which were 3.41 and 5.82 times in magnitude higher than obtained by PDF, respectively. The estimated annual emissions of total-PAHs and total-BaP eq to the ambient environment due to the illegally used FBFO were 23.6 and 0.126 metric tons, respectively, which resulted in a 17.9% and a 25.0% increment of annual emissions from all mobile sources, respectively. These results indicated that the FBFO used illegally by TDVs had a significant impact on PAH emissions to the ambient environment.

    This report summarizes the analysis of fiber-optic strain gauge data obtained from a surface-effect fast patrol boat being studied by the staff at the Norwegian Defense Research Establishment (NDRE) in Norway and the Naval Research Laboratory (NRL) in Washington D.C. Data from two different structural conditions were provided to the staff at Los Alamos National Laboratory. The problem was then approached from a statistical pattern recognition paradigm. This paradigm can be described as a four-part process: (1) operational evaluation, (2) data acquisition & cleansing, (3) feature extraction and data reduction, and (4) statistical model development for feature discrimination. Given that the first two portions of this paradigm were mostly completed by the NDRE and NRL staff, this study focused on data normalization, feature extraction, and statistical modeling for feature discrimination. The feature extraction process began by looking at relatively simple statistics of the signals and progressed to using the residual errors from auto-regressive (AR) models fit to the measured data as the damage-sensitive features. Data normalization proved to be the most challenging portion of this investigation. A novel approach to data normalization, where the residual errors in the AR model are considered to be an unmeasured input and an auto-regressive model with exogenous inputs (ARX) is then fit to portions of the data exhibiting similar waveforms, was successfully applied to this problem. With this normalization procedure, a clear distinction between the two different structural conditions was obtained. A false-positive study was also run, and the procedure developed herein did not yield any false-positive indications of damage. Finally, the results must be qualified by the fact that this procedure has only been applied to very limited data samples. A more complete analysis of additional data taken under various operational and environmental conditions as well as other

    Environmental change and the exploitation of marine resources have had profound impacts on marine communities, with potential implications for ocean biogeochemistry and food security. In order to study such global-scale problems, it is helpful to have computationally efficient numerical models that predict the first-order features of fish biomass production as a function of the environment, based on empirical and mechanistic understandings of marine ecosystems. Here we describe the ecological module of the BiOeconomic mArine Trophic Size-spectrum (BOATS) model, which takes an Earth-system approach to modeling fish biomass at the global scale. The ecological model is designed to be used on an Earth System model grid, and determines size spectra of fish biomass by explicitly resolving life history as a function of local temperature and net primary production. Biomass production is limited by the availability of photosynthetic energy to upper trophic levels, following empirical trophic efficiency scalings, and by well-established empirical temperature-dependent growth rates. Natural mortality is calculated using an empirical size-based relationship, while reproduction and recruitment depend on both the food availability to larvae from net primary production and the production of eggs by mature adult fish. We describe predicted biomass spectra and compare them to observations, and conduct a sensitivity study to determine how the change as a function of net primary production and temperature. The model relies on a limited number of parameters compared to similar modeling efforts, while retaining realistic representations of biological and ecological processes, and is computationally efficient, allowing extensive parameter-space analyses even when implemented globally. As such, it enables the exploration of the linkages between ocean biogeochemistry, climate, and upper trophic levels at the global scale, as well as a representation of fish biomass for idealized studies

    Full Text Available Information on the habitat use of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis is critical for its conservation. The diel biosonar behavior of the porpoise in the port areas of the Yangtze River was examined along with simultaneous observations of fish density and boat traffic. Biosonar pulses from the porpoises were detected for 1233 min (5.77% over a 21,380 min duration of effective observations. In total, 190 (5.63% buzzes (an indication of prey capture attempts were recorded among the 3372 identified click trains. Of the 168 echolocation encounters (bouts of click trains less than eight min apart, 150 (89.3% involved single animals, indicating that solitary porpoises were frequently present and feeding in the port areas. Significant diel patterns were evident involving the biosonar behavior of the porpoises (including click trains and buzzes, fish density and boat traffic. The frequencies of the click trains and buzzes were significantly lower during the day than in the evening and at night, which suggests that porpoises in this region are primarily engaged in crepuscular and nocturnal foraging. The lack of a significant diel pattern in the echolocation encounters indicates the importance of the port in porpoise conservation. A forced feeding schedule may be associated with the lack of a significant correlation between porpoise acoustics and boat traffic. Overall, prey availability appears to be the primary factor that attracts porpoises. Additionally, porpoises tend to migrate or remain downstream in the morning and migrate or remain upstream in the evening, most likely to follow their prey. The findings of this study can be used to improve the conservation of the Yangtze finless porpoise.

    culture operation boat based on ARM (advanced RISC machine) and GPS/INS (global positioning system/inertial navigation system) integrated navigation. The system was mainly composed of ARM controller, GPS/INS integrated navigation devices, GPRS (general packet radio service) communication device, aquatic plant cleaning device, automatic feeding device and paddle wheel driving device. In automatic navigation mode, the ARM controller firstly received and processed the navigation data including position, course and speed from the GPS/INS devices. PWM (pulse width modulation) module and GPIO (general purpose input output) module were called to control the boat sailing, aquatic plant cleaning and automatic feeding simultaneously. The host computer communicated with the ARM controller via GPRS device to monitor the real-time operating status of the ship borne subsystem remotely. In order to simplify the complexity of the traditional calculation method of channel position based on finite target points and reduce channel deviation error of the boat, this paper proposed a new calculation method based on real-time inserting points. This method calculated the current target position of the boat real-timely according to the position of the boat and the turning points of current channel. A new turning and channel switching strategy was also presented in this paper to improve the boat work efficiency and prevent the boat from deviating from the channel because of the high speed. Considering the movement characteristics such as non-linearity, big delay and underdamping of the boat, the course-speed dual-loop control algorithm was designed based on fuzzy PID (proportion integration differentiation). In order to enhance the stability and portability of the system, the ship borne subsystem was designed based on embedded Linux operating system, and the monitoring program of host computer was developed based on Visual Studio 2010 platform and SQL (structured query language) Server 2008

    Utilising extremely different vaporisation properties of boron compounds, the determination procedures of volatile boric acid and total boron using tungsten boat furnace (TBF) ICP-MS and TBF-ICP-AES have been investigated. For the determination of volatile boric acid by TBF-ICP-MS, tetramethylammonium hydroxide (TMAH, Me(4)NOH) was used as a chemical modifier to retain it during drying and ashing stages. As for the total boron, not only non-volatile inorganic boron such as boron nitride (BN), boron carbide (B(4)C), etc. but also boric acid (B(OH)(3)) was decomposed by a furnace-fusion digestion with NaOH to produce sodium salt of boron, a suitable species for the electrothermal vaporisation (ETV) procedure. The proposed method was applied to the analysis of various standard reference materials. The analytical results for various biological and steel samples are described.

    Watercraft-related trauma is the predominant cause of human-induced mortality in manatees (Trichechus manatus latirostris), a federal- and state-listed endangered species. Pyothorax (documented in this case report) and other secondary infections are common sequelae of inhalation of water and the open wounds caused by boat propellers. These secondary infections can lead to the demise of the animal weeks to months after the traumatic incident when external wounds have healed. Diagnosis of underlying disease on physical examination during capture and restraint can be difficult. Acute phase proteins, including serum amyloid A, fibrinogen, and albumin can be used to diagnose inflammatory disease in manatees and improve quality of medical care and husbandry. We also provide the first report of polycystic kidneys in Sirenians. PMID:22102678

    The convention of “walking bridge” on the Dragon Boat Festival in Qingyuan county of Zhejiang province takes the wooden covered bridges as its main activity space and takes a memorial ceremony for gods, blessing and ward-off disease as major contents. Through the activity of “walking three lounge bridges”, the good wishes are placed on the individuals, the families and the entire village. The bridge-walkers are mostly women and the ceremony of the bridge-walking covers three procedures like offering sacrifices, walking the bridges and throwing the four-angle dumplings. There are many reasons for the rite of walking bridge, such as in memory of Quyuan, religionary sacrifice, lounge bridge culture worship and walking sickness, among which walking sickness is most popular and also an explanation that accords with core cultural connotation of exorcising evil spirits and preventing disease on Dragon Boat Festival.%浙江庆元民众的端午“走桥”习俗以木拱廊桥为主要活动空间,以祭神祈福祛病为主要内容,通过“走三桥”来寄托自己对个人、家庭乃至整个村落的美好祝愿。走桥者为女性,仪式包括祭祀、走桥、抛粽三个步骤。对于走桥习俗的解释,有纪念屈原说、宗教祭祀说、廊桥文化崇拜说、走百病说等,其中走百病说最为流行,也是符合端午节辟邪防病的核心文化内涵的一种解释。

  8. Hydrographic and suspended sediment measurements of the Mississippi River plume during the historic 2011 flood: a coupled satellite analysis and boat survey approach to determine an efficiency factor for sediment trapping in the nearshore zone

    2011-12-01

    During the 2011 Mississippi River (MR) flood, sediment carried to sea by the River had the potential to combat wetland loss in some areas. The movement and fate of river sediments is determined by a combination of river plume momentum, and coastal and offshore currents [Walker, 1996; Walker et al., 2005; Rego et al., 2010]. We therefore used a coupled satellite analysis and boat survey approach in order to track mixing and transport of MR plume sediments during one of the largest recorded floods in history. During the flood crest in June of 2010, MR discharge was held at a constant and large value for several weeks, providing a unique experiment that allowed us to study plume structure under steady flow conditions. Sea surface temperature, height, and color data from satellites were employed in order to quantify river plume dispersion, surface sediment concentration [Peckham, 2008; Shi and Wang, 2009] and sediment migration pathways in the nearshore zone for the Mississippi and Atchafalaya Rivers, for the duration of the flood. The boat survey measured current velocity, salinity, temperature and sediment concentration of the MR plume, during the peak of the flood. Although plumes emanating from the MR Delta should contribute significant sediment to the coastal zone [cf. Wright and Nittrouer, 1995; D'Sa and Ho, 2008], our investigation shows that the focused jet of the MR during the flood penetrated the coastal current and contributed little to the coastal sediment budget. Collected data allowed calculation of the hydrodynamic structure of the plume and thus its Potential Vorticity. We show that a novel PV, recently described by Falcini and Jerolmack [2010], works as an efficiency factor: the fraction of sediment emitted from each river plume that is trapped in the nearshore zone (and on marshes) is directly related to the PV of each river effluent. This relation may help to better understand and predict how future floods, or human-constructed river diversions, will

    A cruise of survey in the 2008 Olympics boat-sailing field and adjacent area was carried out on August 28th, 2003. Preliminarily analysis on the eutrophication status was made on the basis of the content of dissolved inorganic nitrogen (DIN), dissolved inorganic phosphate (PO4-P),dissolved oxygen(DO) and chemical oxygen demand (COD) as well. The results indicated that in most of the survey area, water quality was in accordance with the 1st class National Seawater Standard except the average concentration of petroleum hydrocarbon which was beyond the 2nd class National Seawater Standard. The concentrations of PO4-P as well as DIN were mainly influenced by the runoff or drainage from lands, with a comparatively higher concentration in the coastal areas from the Fushan Bay to the Shilaoren bathing beach. The distribution of eutrophication index (EI) showed that part of the survey area was in a state of slight eutrophication. The eutrophication was mostly influenced by the land runoff or drainage and related factors. The sea water quality of the Olympic boat-sailing field was fine and just slightly polluted on the whole.%于2003年8月28日对奥运帆船赛场海域海水水质要素进行了现场调查,并以无机态氮(DIN)、无机态磷(PO4-P)、化学耗氧量(COD)、溶解氧(DO)为化学指标参数,探讨了该海域的富营养化状况.结果表明,奥运会帆船赛场海域除石油烃外,大部分海域符合国家一类海水水质标准,石油烃平均含量超过国家二类水质标准.该海域调查海区PO4-P、DIN主要受陆源排放影响,特别是浮山湾至石老人沿岸海域含量较高.部分区域已经开始呈现轻微富营养化状态,富营养化状况主要受陆源排放等因素的影响.整体上奥运会帆船赛场海域水质良好,污染较轻.

The data of this study resulted from 48 fieldtrips to each of the four localities studied (ports of Recife and Suape, and beaches of Bairro Novo and Piedade, thus totaling 192 days of observations, with approximately 380 hours of actual sampling. Ten types of behavioral activities were counted for Bairro Novo beach and the port areas, but only four for Piedade beach. The greatest flows of boats were recorded in the port of Recife. Fishing boats were the commonest type in the port area of Recife and Bairro Novo beach, while tourist vessels predominated in the port of Suape and Piedade beach. During the observations of encounters between these boats and the estuarine dolphins, neutral reactions predominated for all the vessel types studied. The same type of reaction predominated when the distances at which the interactions between the animals and vessels occurred were correlated.Ainda se sabe pouco sobre o comportamento do boto-cinza, assim como a forma pela qual ele reage a diferentes tipos de embarcações.

    The influx of refugees from Vietnam to the industrialized countries has attracted a certain interest to studies describing the oral health status of these population groups. The present study comprises 361 refugees arriving in Malaysia from Vietnam and collected immediately at the refugee camp on Pulau Bidong. Dental caries, calculus, gingival bleeding and loss of periodontal attachment were recorded. Mean dmft increased from 1.3 for 0-2-yr-olds to 7.4 for 3-5-yr-olds. For 6-9-yr-olds mean DMFT was 2.4 while it ranged between 8.5 and 10.10 for the older age groups. The frequency of secondary lesions was high for all age groups. Calculus increased consistently with age, while gingival bleeding was common even in the youngest age group. Loss of periodontal attachment greater than or equal to 6 mm was rare in all age groups except the oldest (45 yr or older). A strategy for oral health care for these population groups is discussed.

    为了解商船压舱箱沉积物在海洋水生生物入侵过程中扮演的潜在媒介作用,本文利用光学显微镜观察法,研究了停泊于我国舟山港4艘商船压舱箱沉积物中甲藻孢囊的种类组成、孢囊密度、香农-威纳指数(H')和PSP原因种,并对甲藻孢囊种群结构进行了相关性分析.结果表明,鉴定出的甲藻孢囊隶属于5大类,共24种,4份样品中甲藻孢囊的种群结构各有差异,但均检测出能产生麻痹性贝毒(Paralytic Shellfish Poisons,PSP)的甲藻孢囊,如亚历山大藻Alexandrium spp.和链状裸甲藻Gymnodium catenatum.在4艘商船的压舱箱沉积物中均检测出有硅藻分布,其中在富成轮压舱箱沉积物中还检测出3种未知种孢囊.通过相关性分析可知,甲藻孢囊H'值与PSP甲藻孢囊密度占总甲藻孢囊密度的比率呈负相关.甲藻可以通过商船压舱箱沉积物为传播媒介,以孢囊形式来扩大其生物地理分布,提高甲藻物种多样性可有助于降低PSP甲藻的破坏风险.因此,有效处理船只压舱箱沉积物、积极保护当地海洋生物物种多样性,对于降低外来甲藻物种(特别是一些有毒有害种)的赤潮风险和保持当地海洋生态系统的平衡,具有十分重要的意义.%Ballast water of the merchant vessel plays an important role in the invasion of alien marine species which may damage the local marine ecosystem. However, the potential role of the ballast tank sediment in the transmission of the alien species is always underestimated. Using optical microscopic viewing method, the species composition, cyst density, Shannon-Weiner index(H'), Paralytic Shellfish Poisons (PSP) causative species and their relationships of the dinoflagellate cysts from the sediment of four cargo boats at Zhoushan Port were studied, and 24 types of dinoflagellate cysts of 5 groups were identified including some toxic species such as Alexandrium spp. And Gymnodium catenatum which could produce PSP

    端午节是由人们对自然时令转换的理解而生的一个节日,在更多的地方,它是人们面对即将来到的炎热夏天举行的一种群体性的“过关礼”,有着除瘟辟邪、祝福妇幼、整合社区、纪念历史人物等丰富的文化内涵,并因自然地理、人文历史、地方风情的差异而形成多样的社会形态.但是,非物质文化遗产语境下的端午节则延续了现代民族国家意识形态建构的路径,即在民族主义、爱国主义等宏大话语的支配下,原本多样的端午节日渐简约化为粽子和龙舟两个物象,并将其起源都指向伟大的爱国主义诗人屈原.由此,一些地方原本意在祈福禳灾、驱瘟除恶祛病、求子联谊的端午习俗在“非遗化”的过程中,主动添加进了屈原这一象征符号.端午节正在发生的趋同的整体性变迁似乎意味着历史演进并非从简单到复杂,而是从复杂到简约.

  16. The hand that rocks the cradle rocks the boat: the empowerment of women.

    Science.gov (United States)

    Turkel, Ann Ruth

    2004-01-01

    The obstacles to equality for women have changed from external to intrapsychic. The relational characteristics of women, such as nurturing and connecting with others, are now regarded as desirable attributes for the workplace. Adult growth and achievement models are based on the so-called masculine characteristics of separation, individuation, and independence. Relational theory supplies an alternative model called growth-in-connection, which stems from the feminine characteristics of connection, collectivity, and interdependence. Women's fears of exercising power, men's resistance to sharing power, the traditional ways in which women attain power are all concerns that are examined. Real power lies in exercising leadership, which implies risk-taking. Exploring the gender disequilibrium in issues of power--both the female advantage and the female disadvantage-as exemplified by the glass ceiling and its origins--helps to clarify the issues involved in empowerment.

  17. The hand that rocks the cradle should also rock the boat.

    Science.gov (United States)

    Walker, B

    1996-10-01

    The Gender and Development Unit (GADU) was established in 1985 at Oxfam. The unit challenged previous development assumptions; gender analysis required recognition of inequalities based on class, caste, age, and education, as well as on gender. Personal attitudes and professional actions were scrutinized, views on how to achieve gender equity differed, and accusations of cultural imperialism were made. Currently, the organization has a gender policy that is implemented by managers; the "feminist thought police" are gone. Consolidation should occur under a new team. However, questions remain concerning organizational culture; gender roles and relations are culturally determined and culture-specific. There is great diversity in this regard within Oxfam. Some field offices have "family-friendly" policies and procedures, but the "glass ceiling," albeit higher, still exists for women. The ability to read, write, and respond quickly are valued by the work culture, and there is little time to reflect. Discursive expression is unwelcome in the presence of information overload. Both men and women are now making childcare arrangements, and one of the first items on the agenda of the GADU was a workplace nursery. Its establishment came about from "corporate management recognizing the need to look at process as well as product, and from field offices shaping their work cultures to their values." The struggle for gender equality has only changed its form. PMID:12347697

    Full Text Available The extremely popular poetic form from Insular Southeast Asia, the pantun, travelled from its unknown source throughout the Malay Archipelago, first in Malay, then in the languages of Southeast Asia. In the ports and states where they were received, local colour, other idiosyncrasies, references, and linguistic characteristics have been added, and in fact, special forms with special names developed. This basic form is known, composed, and loved in at least 40 dialects of Malay, and 35 non-Malay languages, in the Peninsula and many of the islands of Malaysia and Indonesia. It spread through trade routes, ports, and also via diasporas and colonial economic projects which caused numerous peoples to move, who in turn brought the pantun along with them. It is now the most dynamic single literary form and has the longest history.

    2009-01-01

    Plasmodium of \\emph{Physarum polycephalum} is a single huge (visible by naked eye) cell with myriad of nuclei. The plasmodium is a promising substrate for non-classical, nature-inspired, computing devices. It is capable for approximation of shortest path, computation of planar proximity graphs and plane tessellations, primitive memory and decision-making. The unique properties of the plasmodium make it an ideal candidate for a role of amorphous biological robots with massive parallel information processing and distributed inputs and outputs. We show that when adhered to light-weight object resting on a water surface the plasmodium can propel the object by oscillating its protoplasmic pseudopodia. In experimental laboratory conditions and computational experiments we study phenomenology of the plasmodium-floater system, and possible mechanisms of controlling motion of objects propelled by on board plasmodium.

    1987-01-01

    A static structural analysis of an ocean going patrol vessel subjected to hydrodynamic planning loads is discussed. The analysis required the development of a detailed model that included hull plating, five structural bulkheads, longitudinal and transverse stiffners, and a coarse representation of the superstructure. The finite element model was developed from fabrication drawings using the Navy computer aided design system. Various stress and displacement contours are shown for the entire hull. Because several critical areas appeared to be overstressed, these areas were remeshed for detail and are presented for completeness.

    Directory of Open Access Journals (Sweden)

    1998-10-01

    Full Text Available n the first half of this century, the otter Lutra lutra was regarded as 'nowhere numerous in Latvia but more common in the eastern part of the country than in the western'. Otters were rare in the whole East Baltic in the late 1970s. Field surveys carried out between 1986 and 1991 estimated the minimal population to be 4,000 otters. The aim of this study was to find out whether otters have increased in Latvia since the last survey 10 years ago, to find out what otters eat in late summer in a zone with low fish availability, whether otters occur along the Baltic coast, and whether they feed in the marine environment. A stable or possibly growing otter population was found. Along the coast, otter sign was only found in in the estuaries of small creeks, and little marine food was eaten. Such otters as were indicated were along rocky shores where kelp beds shelter fish, rather than the predominating sandy shores. Unlike the rest of Europe, fish were not the most important prey - amphibians were consumed in equal amounts, and there was a high proportion of insects and other non-fish food eaten. Only in eastern Poland are similar diet proportions found.

    Full Text Available Both Winston S. Churchill (1874-1965 and Franklin D. Roosevelt (1 882-1945 were masters of the English language and effective orators, rallying their people through word and deed to fight as allies against the dictatorial powers during the Second World War. Their public speeches and interviews are replete with proverbs, proverbial expressions, and other phraseologisms. This is also true for their private and secretive letters, messages, memoranda, and telegrams, as can be seen from the materials that Warren F. Kimball edited in the three volumes of Churchill & Roosevelt: The Complete Correspondence (Princeton, NJ: Princeton University Press, 1984. The proverbial language, especially metaphorical texts referring to the body, animals, and the military, gives their important communications a lively and humane flavor that illustrates their deep friendship, trust, and support of each other. Frequently used as metaphorical arguments, these proverbial interjections into an otherwise factual epistolary exchange from 1933 to 1945 bear witness to the determination of these two world leaders to win the struggle for a free world.

    2006-07-01

    Summary: The swimming classroom is a particular environmental education programme. Since 2002 school classes are taught aboard the solar ferry Helio at the Lower Lake Constance. Schoolboys and girls as well as teachers have the opportunity to enlarge their knowledge about Lake Constance, its natural environment and the solar ferry Helio. They also get informed about photovoltaic systems, water pollution control and environment-friendly tourism in the Lake Constance region. Solar ferry is most suitable for nature and adventure pedagogy as well as experimental instruction. School classes and advanced training groups can easily carry out a comprehensive programme aboard the Helio and experience nature and solar technology cruising on the lake. Issues are - Energy/Photovoltaic - Limnology - Life in and on the water - Water pollution control - Geography/Landscape development. (orig.)

  19. Hydrodynamics of a fixed camphor boat at the air-water interface

    A camphor tablet, when introduced at the air-water interface undergoes sublimation and the camphor vapour spreads radially outwards across the surface. This radial spreading of camphor is due to Marangoni forces setup by the camphor concentration gradient. We report experiments on the hydrodynamics of this process for a camphor tablet held fixed at the air-water interface. During the initial transient, the time-dependent spread radius R (t) of camphor scales algebraically with time t (R (t) ~t 1 / 2) in agreement with empirical scalings reported for spreading of volatile oils on water surface. But unlike surfactants, the camphor stops spreading when the influx of camphor from the tablet onto the air-water interface is balanced by the outflux of camphor due to evaporation, and a steady-state condition is reached. The spreading camphor however, shears the underlying fluid and sets up bulk convective flow. We explain the coupled steady-state dynamics between the interfacial camphor spreading and bulk convective flow with a boundary layer approximation, supported by experimental evidence. This work was supported by the Collective Interactions Unit, OIST Graduate University.

  3. A comparison between boat-based and diver-based methods for quantifying coral bleaching

    2015-01-01

    Recent increases in both the frequency and severity of coral bleaching events have spurred numerous surveys to quantify the immediate impacts and monitor the subsequent community response. Most of these efforts utilize conventional diver-based methods, which are inherently time-consuming, expensive, and limited in spatial scope unless they deploy large teams of scientifically-trained divers. In this study, we evaluated the effectiveness of the Along-Track Reef Imaging System (ATRIS), an automated image-acquisition technology, for assessing a moderate bleaching event that occurred in the summer of 2011 in the Florida Keys. More than 100,000 images were collected over 2.7 km of transects spanning four patch reefs in a 3-h period. In contrast, divers completed 18, 10-m long transects at nine patch reefs over a 5-day period. Corals were assigned to one of four categories: not bleached, pale, partially bleached, and bleached. The prevalence of bleaching estimated by ATRIS was comparable to the results obtained by divers, but only for corals > 41 cm in size. The coral size-threshold computed for ATRIS in this study was constrained by prevailing environmental conditions (turbidity and sea state) and, consequently, needs to be determined on a study-by-study basis. Both ATRIS and diver-based methods have innate strengths and weaknesses that must be weighed with respect to project goals.

    Full Text Available Organizing and managing channels of distribution is an important marketing task. Due to the emergence of electronic commerce on the Internet, e-channel distribution systems have been adopted by many manufacturers. However, academic and anecdotal evidence both point to the pressures arising from this new e-channel manufacturing environment. Question marks therefore remain on how the addition of this e-channel affects the traditional marketing strategies of leasing and selling. We set up several two-period dual-channel models in which a manufacturer sells a durable product through both a manufacturer-owned e-channel and an independent reseller (leaser who adopts selling (leasing to consumers. Our main results indicate that, direct selling cost aside, product durability plays an important role in shaping the strategies of all members. With either marketing strategy, the additional expansion of an e-channel territory may secure Pareto gains, in which all members benefit.

    Full Text Available In a recent ISJ paper, “Island Archaeology: In Search of a New Horizon”, Boomert and Bright (2007 argue that the field of “island archaeology” should be replaced by an “archaeology of maritime identity”. We disagree and counter that although islands share many physical, biological, and cultural similarities with continental coasts, coastal zones also grade uninterruptedly into riverine, lacustrine, and terrestrial landscapes, raising questions about the validity of their concept of the archaeology of maritime identity. In our view, island archaeology (the application of archaeology to island settings, regardless of past biogeographical underpinnings, has made major contributions to understanding the historical ecology, human impacts, and cultural developments of islands around the world. A focus on islands by archaeologists has encouraged scholars to study the history of island and maritime societies within a comparative framework that is useful for breaking out of the often provincial focus on a single island or archipelago.

  6. Economic value of instream flow for non-commercial whitewater boating using recreation demand and contingent valuation methods.

    Loomis, John; McTernan, James

    2014-03-01

    Whitewater river kayaking and river rafting require adequate instream flows that are often adversely affected by upstream water diversions. However, there are very few studies in the USA of the economic value of instream flow to inform environmental managers. This study estimates the economic value of instream flow to non-commercial kayakers derived using a Travel Cost Method recreation demand model and Contingent Valuation Method (CVM), a type of Contingent Behavior Method (CBM). Data were obtained from a visitor survey administered along the Poudre River in Colorado. In the dichotomous choice CVM willingness to pay (WTP) question, visitors were asked if they would still visit the river if the cost of their trip was $Y higher, and the level of $Y was varied across the sample. The CVM yielded an estimate of WTP that was sensitive to flows ranging from $55 per person per day at 300 Cubic Feet per Second (CFS) to a maximum $97 per person per day at flows of 1900 CFS. The recreation demand model estimated a boater's number of trips per season. We found the number of trips taken was also sensitive to flow, ranging from as little as 1.63 trips at 300 CFS to a maximum number of 14 trips over the season at 1900 CFS. Thus, there is consistency between peak benefits per trip and number of trips, respectively. With an average of about 100 non-commercial boaters per day, the maximum marginal values per acre foot averages about $220. This value exceeds irrigation water values in this area of Colorado.

    Full Text Available Abstract - Chick lit is a genre comprised of books chiefly written by women for women. These books are mainly characterized by the tone, which is very confidential and personal, and often relies on the use of colloquial and slangy (and occasionally obscene expressions, by the use of humour, and by the numerous references to popular culture. This paper aims at analyzing the strategies used in the Italian translation of one of the best-known examples of the genre, Helen Fielding’s Bridget Jones’s Diary, taking two frames of reference. First of all, the analysis will try to identify in the target text the distinctive universal features observed in computer-based corpus translation (Baker 1996, namely explicitation, simplification and normalization. Secondly, it will consider the translation in terms of Venuti’s dichotomy of translation strategies into domestication and foreignization (1995. Riassunto -Il chick lit è un genere letterario costituito principalmente da romanzi scritti perlopiù da autrici donne per un pubblico femminile. I romanzi chick-lit sono caratterizzati dal tono confidenziale e personale, dall’uso di espressioni colloquiali e slang (e occasionalmente volgari, dalla presenza costante di humour e dai numerosi riferimenti alla pop culture contemporanea. Questo saggio intende analizzare le strategie utilizzate nella traduzione italiana di uno degli esempi più rappresentativi del genere, ovvero Bridget Jones’s Diary di Helen Fielding, utilizzando due modelli di riferimento. Innanzitutto, lo studio tenterà di identificare la presenza degli universali traduttivi osservati nei corpus-based translation studies (Baker 1996, ovvero explicitation, simplification e normalization. Successivamente, si analizzerà la traduzione secondo la teoria delle strategie traduttive proposta da Venuti (1995, ovvero domestication e foreignization.
