Dust is a ubiquitous phenomenon which must be explicitly addressed during upcoming robotic and human planetary exploration missions. The near term plans to revisit the moon as a stepping stone to further exploration of Mars and beyond brings places a primary emphasis on evaluation and mitigation of lunar dust. Comprised of regolith particles ranging in size from tens of nanometers to microns, lunar dust is a manifestation of the complex interaction of the lunar soil with multiple mechanical, electrical, and gravitational effects. Charged dust particles could levitate in the solar wind plasma environment, and may mediate significant differential charging effects with potential harmful consequences, as well as pose toxicological health problems when inhaled. This work outlines the scientific basis for lunar dust behavior, it's characteristics and potential effects, and surveys several potential strategies for its control and mitigation both for surface operations and inside the habitable working volumes of a lunar outpost. This paper presents a preliminary analysis of dust as a component of the lunar environment, an assessment of it's potential impacts on lunar exploration, as well as a perspective on lessons learned and information still to be gained from prior exploration. Also presented are the current perspective and planning for dust management activities within NASA's Exploration technology Development Program.

In this paper, we propose a new adaptation system for a manual wheelchair to reduce the load on the upper extremity of the user during wheelchair manipulation and also to increase the efficiency of the wheelchair propulsion. The proposed adaptation system is designed to provide optimal position of the handrim and the desired angular position of seat and backrest of the wheelchair based on the user's body function. Electromyogram signals from the user muscles, heart rate signals, oxygen uptake, amount of applied pressure on the seat and backrest, force/moment applied on the handrim, joint force/moment of the upper extremity and analytical results using the dynamic manipulating force ellipsoid and the driving force contribution figure are used as index parameters for the proposed adaptation system.

The large-scale interim spent fuel dry storage facilities from nuclear power plantsare planned to start operation by 2010 in Japan. The requirements of these facilities area big spent fuel storage capacity and a restricted site usage close to the boundary. Thesecause a strong request of precise and realistic dose estimation for licensing *** resolve this difficulty three dimensional Monte Carlo calculation methods areintroduced, which is always requested to compare the benchmark experiment of theshielding system for the verification of procedure and statistical errors. Here, two kindsof shielding benchmark experiments;the huge duct streaming and the cask shadowshielding experiments, were newly prepared to get these absent data. As a first step, the huge duct streaming experiment is outlined and the obtainedresults are discussed. Neutron and gamma flux and dose distributions in and around thestreaming duct were measured by moderating type neutron detectors, neutrondosimeters, activation foils, solid state track detectors (CR-39), thermoluminescentdosimeters, glass dosimeters, etc. These results are also compared with the Monte Carlocalculations. Through these procedures the know-how of the spatial dose estimation inand around a huge streaming duct were obtained.

GROUND WATER MONITORING AND REMEDIATION 1996年第1期16卷 67-72页

作者： Newcomer, DR Hall, SH Vermeul, VR Darrell R. Newcomer (Pacific Northwest National Laboratory P.O. Box 999 Richland WA 99352) is a research hydrologist in the Engineering Technology Division Battelle Pacific Northwest National Laboratories. He graduated with a B.S. in geology from Western Washington University and an M.S. in hydrogeology from Montana College of Mineral Science and Technology. He has been involved in several environmental ground water monitoring and restoration projects since joining Battelle including the development of new remediation technologies. He has recently been involved with the development of an in situ bioremediation technology to degrade carbon tetrachloride in ground water. Stephen Hall (Pacific Northwest National Laboratory P. O. Box 999 Richland WA 99352) holds a bachelor's degree in chemistry and a master's degree in geology both from the University of Wisconsin and is a certified professional geologist. He has extensive industrial experience in analytical chemistry and the extractive metallurgy of precious metals and uranium. Most recently as a senior research scientist with Pacific Northwest Laboratory he developed advanced methods for hydrogeologic aquifer characterization using flow tracers. He is currently engaged in environmental restoration of mined ore bodies and in the commercialization of aquifer thermal energy storage as an energy conservation method used in heating and air conditioning. Vince R. Vermeul (Pacific Northwest National Laboratory P.O. Box 999 Richland WA 99352) is a research scientist in the Environmental Technology Division of Battelle Pacific Northwest National Laboratories where he works on interdisciplinary teams assembled to conduct remedial investigations and develop/implement innovative remediation technologies. Vermeul received an M.S. degree in environmental engineering from Oregon State University in 1990.

Depth-discrete aquifer information was obtained using recently developed adaptations and improvements to conventional characterization techniques. These improvements included running neutron porosity and bulk density geophysical logging tools through a cased hole, performing an enhanced point-dilution tracer test for monitoring tracer concentration as a function of time and depth, and using pressure derivatives for diagnostic and quantitative analysis of constant rate discharge test data. Data results from the use of these techniques were used to develop a conceptual model of a heterogeneous aquifer. Depth-discrete adquifer information was required to effectively design field-scale deployment and monitoring of an in situ bioremediation technology. Geophysical logging and point-dilution tracer test results provided the relative distribution of porosity and horizontal hydraulic conductivity, respectively, with depth and correlated well. Hydraulic pumping tests were conducted to estimate mean values for transmissivity and effective hydraulic conductivity. Tracer test and geophysical logging results indicated that ground water flow was predominant in the upper approximate 10 feet of the aquifer investigated. These results were used to delineate a more representative interval thickness for estimating effective hydraulic conductivity. Hydraulic conductivity, calculated using this representative interval, was estimated to be 73 ft/d, approximately three times higher than that calculated using the full length of the screened test interval.

In flood mapping, it is often required to combine a variety of information sources and techniques. This integration can yield an optimal, multi-perspective and comprehensive assessment of the flood susceptibility in a target area such as the city of Douala in Cameroon. Available facts indicate that Douala is highly susceptible to flood especially in the coastal and nearshore areas. In this study, we integrated eleven flood conditioning factors (elevation, slope, topographic wetness index, terrain ruggedness index, distance to water bodies, drainage density, annual rainfall distribution, land use/land cover, soil texture, normalised difference vegetation index and modified normalised difference water index) to investigate the susceptibility to flooding. The adopted methodology combines Geographic Information System (GIS) and Remote sensing techniques, and the Logistic Regression (LR) statistical model. The generated flood map was divided into five susceptibility classes of very low, low, moderate, high and very high;and the overall accuracy of the prediction was assessed. In the results, low and very low flood susceptible areas have a susceptibility index less than or equal to 0.302 and very highly susceptible areas have an index greater than 0.788. The flood susceptibility map revealed that approximately 72.1% of Douala is less susceptible to flood while about 20% of its area (mostly urbanised and populated areas) are highly or very highly susceptible. The LR model shows accuracy, precision and F1 score higher than 0.85 which indicates its theoretical reliability. This result highlights the possibility to use open-source data and tools to assess susceptibility to flood with the aim of developing resilience plans or flood emergency response/preparedness plans. This methodology which is less complex and of reduced technical and financial constraints seems reliable and replicable. The susceptibility maps developed are useful tools for decision makers, city planners and

According to the United Nations Office for Disaster Risk Reduction,1 the number of global weather-related disasters in the past decades has been estimated at 90% of the total number of disasters. These are likely to increase in severity and frequency with current and forecasted global climate changes. Disaster risk monitoring using space technology and machine learning has become essential for minimizing and managing the consequences of natural disasters. However, flood assessment and data collection remain deficient in many parts of developing countries. Recent studies in Cameroon have identified socio-economic limitations and low adaptive capacity to manage floods that threaten and expose populations to vulnerability and danger. The increasing availability of smartphones and social media data allows individuals to directly document floods in real-time and otherwise poorly observed areas. However, these data are rarely used for flood assessment purposes in developing countries. This information, in synergy with remote sensing, can help disaster managers and rescuers determine routes and maps to support flood response as well as post-flood activities, such as calibrating flood hydrodynamic models. The paper will focus on integrating community social media with satellite remote sensing data to assess and assist in flood disaster emergency response and preparedness in Douala Estuary in Cameroon. © 2021 International Astronautical Federation, IAF.

Membrane trafficking to the protein storage vacuole （PSV） is a specialized process in seed plants. However, this trafficking mechanism to PSV is poorly understood. Here, we show that three types of Beige and Chediak-Higashi （BEACH）-domain proteins contribute to both vacuolar protein transport and effector- triggered immunity （ETI）. We screened a green fluorescent seed （GFS） library of Arabidopsis mutants with defects in vesicle trafficking and isolated two allelic mutants gfs3 and gfs12 with a defect in seed pro- tein transport to PSV. The gene responsible for the mutant phenotype was found to encode a putative pro- tein belonging to group D of BEACH-domain proteins, which possess kinase domains. Disruption of other BEACH-encoding loci in the gfs12 mutant showed that BEACH homologs acted in a cascading manner for PSV trafficking. The epistatic genetic interactions observed among BEACH homologs were also found in the ETI responses of the gfs12 and gfs12 bchb-1 mutants, which showed elevated avirulent bacterial growth. The GFS12 kinase domain interacted specifically with the pleckstrin homology domain of BchCl. These results suggest that a cascade of multiple BEACH-domain proteins contributes to vacuolar protein transport and plant defense.

Despite the limits inherent within linearized frequency-domain ship motion and wave load computer codes, strip theory has been found to provide the design community with a fairly robust, practical design tool with reasonable accuracy for most conventional displacement monohulls. However, the advent of new design concepts including multi-hulls and application of new materials as well as the push to incorporate reliability methods within surface ship structural design criteria has highlighted the need for more rigorous methods of developing a lifetime load spectrum. In this paper, a multilevel computation system for predicting ship motions and wave loads, up through and including extreme sea conditions, is presented. This system includes a traditional strip theory approach and newly developed linear and nonlinear three-dimensional time-domain methods. The new nonlinear methods are currently in the process of being validated by the U.S. Navy. The status of the current development is presented. Sample numerical results from the new nonlinear methods are compared with both linear frequency domain predictions and model tests.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent Engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.
