    The last twenty years have seen major advances in the electronics industry. Perhaps the most significant aspect of these advances has been the significant role that electronic equipment plays in almost all product markets. Even though electronic equipment is used in a broad base of applications, many future applications have yet to be conceived. This versatility of electron­ ics has been brought about primarily by the significant advances that have been made in integrated circuit technology. The electronic product user is rarely aware of the integrated circuits within the equipment. However, the user is often very aware of the size, weight, mod­ ularity, maintainability, aesthetics, and human interface features of the product. In fact, these are aspects of the products that often are instrumental in deter­ mining its success or failure in the marketplace. Optimizing these and other product features is the primary role of Electronic Equipment Packaging Technology. As the electronics industry continues to pr...

    Athletic field turf should match the quality and interest of the public attraction regarded high-level sports. The attraction itself includes a complex of many factors such as economy, science, technology and management. Athletic field turf may include both natural turf and artificial turf. In order to take advantage of both types of turf, a new planting technique for natural-artificial turf has been suggested. Natural-artificial turf refers to the turf grass system composed of natural turf grass, special machinery management, basic ground equipment and some artificial fiber materials mixed in the natural turf surface and root-zone using modern mechanical equipment. To further understand the characteristics of natural-artificial turf, this study reports bounce rate and rolling distance of natural-artificial turf after mimic traffic processing is tested with natural turf as control. The twist friction, sliding friction, bounce rate and rolling distance of natural-artificial turf increase with traffic intensity. Group A4 and A6 show obviously higher twist friction and sliding friction than other groups.%为进一步了解天然草与人造草混合系统草坪的特点,以纯天然草坪为对照,通过模拟践踏处理,对混合系统草坪表面反弹、摩擦及滚动等性能进行了测定研究.结果表明:混合系统草坪的扭动摩擦力、滑动摩擦力、反弹率及滚动距离均随践踏胁迫的强度增加而具有上升的特点,其中间隔铺设4 cm人造草坪处理(A4)的混建草坪和间隔铺设6 cm人造草坪处理(A6)的混建草坪均始终保持较高的扭动摩擦力与滑动摩擦力,明显高于其他处理,可以推广应用.

    In an emergency, life support can be provided during recompression or hyperbaric oxygen therapy using very basic equipment, provided the equipment is hyperbaric-compatible and the clinicians have appropriate experience. For hyperbaric critical care to be provided safely on a routine basis, however, a great deal of preparation and specific equipment is needed, and relatively few facilities have optimal capabilities at present. The type, size and location of the chamber are very influential factors. Although monoplace chamber critical care is possible, it involves special adaptations and inherent limitations that make it inappropriate for all but specifically experienced teams. A large, purpose-designed chamber co-located with an intensive care unit is ideal. Keeping the critically ill patient on their normal bed significantly improves quality of care where this is possible. The latest hyperbaric ventilators have resolved many of the issues normally associated with hyperbaric ventilation, but at significant cost. Multi-parameter monitoring is relatively simple with advanced portable monitors, or preferably installed units that are of the same type as used elsewhere in the hospital. Whilst end-tidal CO₂ readings are changed by pressure and require interpretation, most other parameters display normally. All normal infusions can be continued, with several examples of syringe drivers and infusion pumps shown to function essentially normally at pressure. Techniques exist for continuous suction drainage and most other aspects of standard critical care. At present, the most complex life support technologies such as haemofiltration, cardiac assist devices and extra-corporeal membrane oxygenation remain incompatible with the hyperbaric environment.

  16. Micromechanics of carbon nanotube turfs

    Science.gov (United States)

    Torabi, Hamid

    Complex structures consisting of intertwined, nominally vertical carbon nanotubes (CNTs) are called turfs. Unique electrical, thermal, optical, and permeability properties of these turfs have attracted growing attention during the past decade, and have rendered them as appropriate candidates for applications such as contact thermal switches. These properties are controlled by the details of the turf microstructures. Due to the application of the turfs in different fields, they are subjected to different loading conditions. Deformation changes the microstructure of a CNT turf, which results in change of effective properties. Many researchers have recently studied the collective mechanical behavior of CNT turfs to compression loading, as this behavior determines their performance. However, their complex and intertwined structure must be investigated in more details to find the relation between their deformation and their underlying morphology. Under uniform compression experiments, CNT turfs exhibit irreversible collective buckling of a layer preceded by reorientation of CNT segments. Experimentally observed independence of the buckling stress and the buckling wavelength on the turf width suggests the existence of an intrinsic material length. To investigate the relationship the macroscopic material properties and the statistical parameters describing the nano-scale geometry of the turf (tortuosity, density and connectivity) we develop a nano-scale computational model, based on the representation of CNT segments as elastica finite elements with van der Waals interactions. The virtual turfs are generated by means of a constrained random walk algorithm and subsequent relaxation. The resulting computational model is robust and is capable of modeling the collective behavior of CNTs. We first establish the dependence of statistical parameters on the computational parameters used for turf generation, then establish relationships between post-buckling stress, initial

    Titanium alloys, especially Ti-6Al-4V, are widely used for the aeroengine and space equipment because of their high strength ratio and excellent resistance to heat and corrosion. But this material is difficult to manufacture by conventional plastic forming technology. It has been reported that Ti-6Al-4V shows extensive ductility (superplasticity), more than 1000 percent under the condition of both low straining rate and high temperature ranges. Superplastic forming technology applying this characteristic is widely known as one of the most cost-effective methods to save material. At the plant, gas argon blowing equipment for the superplastic forming technology has been developed and 'V2500 nose fairing' and 'fuel tank of the H-II rocket second stage reaction control system' have been manufactured. This paper describes the superplastic forming equipment and the two products above.

    The objective of this research was to develop a multiobjective optimization model to deploy emissions reduction technologies for nonroad construction equipment to reduce emissions in a cost-effective and optimal manner. Given a fleet of construction equipment emitting different pollutants in the nonattainment (NA) and near -nonattainment (NNA) counties of a state and a set of emissions reduction technologies available for installation on equipment to control pollution/emissions, the model assists in determining the mix of technologies to be deployed so that maximum emissions reduction and fuel savings are achieved within a given budget. Three technologies considered for emissions reduction were designated as X, Y, and Z to keep the model formulation general so that it can be applied for any other set of technologies. Two alternative methods of deploying these technologies on a fleet of equipment were investigated with the methods differing in the technology deployment preference in the NA and NNA counties. The model having a weighted objective function containing emissions reduction benefits and fuel-saving benefits was programmed with C++ and ILOG-CPLEX. For demonstration purposes, the model was applied for a selected construction equipment fleet owned by the Texas Department of Transportation, located in NA and NNA counties of Texas, assuming the three emissions reduction technologies X, Y, and Z to represent, respectively, hydrogen enrichment, selective catalytic reduction, and fuel additive technologies. Model solutions were obtained for varying budget amounts to test the sensitivity of emissions reductions and fuel-savings benefits with increasing the budget. Different mixes of technologies producing maximum oxides of nitrogen (NO(x)) reductions and total combined benefits (emissions reductions plus fuel savings) were indicated at different budget ranges. The initial steep portion of the plots for NO(x) reductions and total combined benefits against budgets

    Cold atmospheric plasma (CAP) technology is very fast and effective in inactivation of all kinds of pathogens. It is used in hygiene and especially in medicine, since the plasma treatment can be applied to sensitive surfaces, like skin, too. In a first study to use CAP for the decontamination of space equipment we could show its potential as a quite promising alternative to the standard "dry heat" and H2O2 methods [Shimizu et al. Planetary and Space Science, 90, 60-71. (2014)]. In a follow-on study we continue the investigations to reach high application level of the technology. First, we redesign the actual setup to a plasma-gas circulation system, increasing the effectivity of inactivation and the sustainability. Additionally, we want to learn more about the plasma chemistry processes involved in the inactivation. Therefore, we perform detailed plasma and gas measurements and compare them to numerical simulations. The latter will finally be used to scale the decontamination system to sizes useful also for larger space equipment. Typical materials relevant for space equipment will be tested and investigated on surface material changes due to the plasma treatment. Additionally, it is planned to use electronic boards and compare their functionality before and after the CAP expose. We will give an overview on the status of the plasma decontamination project funded by the Bavarian Ministry of Economics.

    This document presents a strategy for a comprehensive program plan that is applicable to the Combustion Equipment Program of the DOE Office of Industrial Technologies (the program). The program seeks to develop improved heating equipment and advanced control techniques which, by improvements in combustion and beat transfer, will increase energy-use efficiency and productivity in industrial processes and allow the preferred use of abundant, low grade and waste domestic fuels. While the plan development strategy endeavors to be consistent with the programmatic goals and policies of the office, it is primarily governed by the needs and concerns of the US heating equipment industry. The program, by nature, focuses on energy intensive industrial processes. According to the DOE Manufacturing Energy Consumption Survey (MECS), the industrial sector in the US consumed about 21 quads of energy in 1988 in the form of coal, petroleum, natural gas and electricity. This energy was used as fuels for industrial boilers and furnaces, for agricultural uses, for construction, as feedstocks for chemicals and plastics, and for steel, mining, motors, engines and other industrial use over 75 percent of this energy was consumed to provide heat and power for manufacturing industries. The largest consumers of fuel energy were the primary metals, chemical and allied products, paper and allied products, and stone, clay and glass industry groups which accounted for about 60% of the total fuel energy consumed by the US manufacturing sector.

    2011-11-01

    Football codes (rugby union, soccer, American football) train and play matches on natural and artificial turfs. A review of injuries on different turfs was needed to inform practitioners and sporting bodies on turf-related injury mechanisms and risk factors. Therefore, the aim of this review was to compare the incidence, nature and mechanisms of injuries sustained on newer generation artificial turfs and natural turfs. Electronic databases were searched using the keywords 'artificial turf', 'natural turf', 'grass' and 'inj*'. Delimitation of 120 articles sourced to those addressing injuries in football codes and those using third and fourth generation artificial turfs or natural turfs resulted in 11 experimental papers. These 11 papers provided 20 cohorts that could be assessed using magnitude-based inferences for injury incidence rate ratio calculations pertaining to differences between surfaces. Analysis showed that 16 of the 20 cohorts showed trivial effects for overall incidence rate ratios between surfaces. There was increased risk of ankle injury playing on artificial turf in eight cohorts, with incidence rate ratios from 0.7 to 5.2. Evidence concerning risk of knee injuries on the two surfaces was inconsistent, with incidence rate ratios from 0.4 to 2.8. Two cohorts showed beneficial inferences over the 90% likelihood value for effects of artificial surface on muscle injuries for soccer players; however, there were also two harmful, four unclear and five trivial inferences across the three football codes. Inferences relating to injury severity were inconsistent, with the exception that artificial turf was very likely to have harmful effects for minor injuries in rugby union training and severe injuries in young female soccer players. No clear differences between surfaces were evident in relation to training versus match injuries. Potential mechanisms for differing injury patterns on artificial turf compared with natural turf include increased peak torque and

    Buildings account for almost a third of final energy consumption globally and are an equally important source of CO2 emissions. Currently, both space heating and cooling as well as hot water are estimated to account for roughly half of global energy consumption in buildings. Energy-efficient and low/zero-carbon heating and cooling technologies for buildings have the potential to reduce CO2 emissions by up to 2 gigatonnes (Gt) and save 710 million tonnes oil equivalent (Mtoe) of energy by 2050. Most of these technologies -- which include solar thermal, combined heat and power (CHP), heat pumps and thermal energy storage -- are commercially available today. The Energy-Efficient Buildings: Heating and Cooling Equipment Roadmap sets out a detailed pathway for the evolution and deployment of the key underlying technologies. It finds that urgent action is required if the building stock of the future is to consume less energy and result in lower CO2 emissions. The roadmap concludes with a set of near-term actions that stakeholders will need to take to achieve the roadmap's vision.

    Market and technical information on gas fired equipment used in the commercial food service sector in Canada and in each province or territory was presented. Results of a market study and technology review were integrated to establish energy consumption and energy saving potential in this sector. Eight categories of commercial cooking appliances were studied. They were: fryers, griddles, broilers, ranges, ovens, tilting skillets, steam kettles and steamers. Focus was on gas fired appliances, although electric appliances were also included. The total energy consumption of the appliances was estimated at 76,140.37 GBtu in 1994. Gas appliances accounted for 63 per cent of the total inventory and consumed 83 per cent of the total energy used. Cooking energy efficiencies for the gas fired commercial cooking equipment ranged from 10 per cent to 60 per cent. The electric appliances had cooking energy efficiencies ranging from 35 per cent to 95 per cent. A list of recommendations were made for the many opportunities to introduce higher efficiency commercial cooking appliances, essential to slow down or to stabilize the energy consumption of cooking appliances over the next decade. 66 refs., 14 tabs., 18 figs.

    This report describes for the first time the state-of-the-art in conducting polymer technology specifically relating to electric power apparatus for transmission, distribution and generation. Thirty-two new applications in power equipment are proposed and assessed. The areas of the proposed applications include solid dielectric cable, oil-filled cable, capacitors, transformers, rotating machines, bushings, surge supressors, vacuum interrupters, gas-insulated equipment, and miscellaneous applications. The best applications will result in improved reliability and efficiency, design innovations, and simpler manufacturing procedures by taking advantage of the particular characteristics of conducting polymers. These characteristics include good control of conductivity over a range of 10{sup {minus}8} to 10{sup 3} S/cm, compatibility with organic compounds, simple preparation and development of anisotropic conductivity by polymer orientation. The proposed applications were evaluated according to technical impact, probability of success, economic impact, and time frame for implementation. The state-of-the-art of conducting polymers is also reviewed and areas requiring further research for these applications are discussed. Because of substantial recent progress is developing more practical conducting polymer materials, now is an excellent time to pursue the additional research needed. 37 refs., 16 figs., 15 tabs.

    2014-12-01

    Complex structures consisting of intertwined, nominally vertical carbon nanotubes (CNTs) are called turfs. Under uniform compression experiments, CNT turfs exhibit irreversible collective buckling of a layer preceded by reorientation of CNT segments. Experimentally observed independence of the buckling stress and the buckling wavelength on the turf width suggests the existence of an intrinsic material length. To investigate the relationship the macroscopic material properties and the statistical parameters describing the nano-scale geometry of the turf (tortuosity, density and connectivity) we develop a nano-scale computational model, based on the representation of CNT segments as elastica finite elements with van der Waals interactions. The virtual turfs are generated by means of a constrained random walk algorithm and subsequent relaxation. The resulting computational model is robust and is capable of modeling the collective behavior of CNTs. We first establish the dependence of statistical parameters on the computational parameters used for turf generation, then establish relationships between post-buckling stress, initial elastic modulus and buckling wavelength on statistical turf parameters. Finally, we analyze the reorientation of buckling planes of individual CNTs during the collective buckling process.

    2016-03-01

    Full Text Available This paper considers the question of an optical unit designing for transmitting power laser radiation through an optical fiber. The aim of this work is designing a simple construction unit with minimized reflection losses. The source of radiation in the optical unit described below is an ultraviolet laser with diode pumping. We present the general functioning scheme and designing features for the three main parts: laser beam deflecting system, laser beam dump and optical unit control system. The described laser beam deflection system is composed of a moving flat mirror and a spherical scattering mirror. Comparative analysis of the production technology for such mirrors was carried out, and, as a result, the decision was made to produce both mirrors of 99.99 % pure molybdenum without coating. A moving mirror deflects laser emission from a source through a fiber or deflects it on a spherical mirror and into the laser beam dump, moreover, switching from one position to another occurs almost immediately. It is shown that a scattering mirror is necessary, otherwise, the absorbing surface of the beam dump is being worn out irregularly. The laser beam dump is an open conical cavity, in which the conical element with its spire turned to the emission source is placed. Special microgeometry of the internal surface of the beam dump is suggested for the better absorption effect. An optical unit control system consists of a laser beam deflection system, laser temperature sensor, deflection system solenoid temperature sensor, and deflection mirror position sensor. The signal processing algorithm for signals coming from the sensors to the controller is described. The optical unit will be used in special technological equipment.

It can be met by implementing the fundamentals of agroecology (use of biodiversity, integration of agriculture in landscapes, closure of flow loops in the context of a broad and renewed offer of technologies: agro-equipment, biotechnology, digital technologies… This article explores the role that agro-equipment and digital services can play in this transition. These technologies contribute through various levers to the agro-ecological transition: by improving farming efficiency (more service rendered for the same environmental impact, by precision farming (adaptation of the operations to the needs of the plant or the animal based on a monitoring–diagnosis–recommendation cycle and by the development of specialized machinery helping the farmer to achieve “flow loop-closing” (at the plot level, by maintaining the soil quality, or at the farm level, with the recycling of organic effluents or to take advantage of biodiversity (e.g., with agro-equipment adapted to mixed crops. The technological bricks that are requested and for which advances are expected are: sensors (to measure plant or animal needs and associated digital technologies (information transfer, data processing, precision technologies for input application, robotics, specialized machines to manage soil cover and weeds, or for agroforestry. The brakes and engines for innovation in agro-equipment are studied. The brakes are the generally small structure of the farm manufacturing companies, the deficit of the demand from farmers and the complexity − either real or perceived − of these equipments. To encourage innovation, several levers are to be used: involving users in the design of agro-equipments, creating financial incentives for innovative equipment purchase, and training end-users, prescribers and dealers to the high potential of these new technologies. In conclusion, putting agro-equipment and digital technology

    Full Text Available The article is devoted features of the application composite materials in radar technology for example adjustment of the development technology of the reflector antenna device DMRL-S - radar for monitoring meteorological conditions.Russian and foreign analogues DMRL-S are made of aluminum, which no longer meets modern requirements for strength and weight. Also aluminum reflectors are not temperature stable. Composite materials are characterized by higher values of specific characteristics: temporary resistance, endurance limit, stiffness, elastic modulus, and less prone to cracking. The use of such materials improves the strength, rigidity and durability.For the manufacture of the DMRL-C reflector used composite materials based on epoxy resins reinforced with fiberglass (both unidirectional and woven. To increase the rigidity and weight reflector is made in the form of three-layer sandwich fiberglass panels with honeycomb core variable height. Design work was carried out in a CAD Siemens NX8.0 / Unigraphics, through which was established mathematical model layered reflector, as well as all accessories used in the manufacture. With the program NX Nastran was held strength calculation and analysis of stiffness on the finite element method.After the manufacture of the product, we measured the standard deviation of the working surface of the reflector from the theoretical surface using a three-dimensional laser scanner. Measurements were made at different angular positions of the reflector, and when loading. It is shown that the maximum strain in the operating modes of operation across the surface of the product does not exceed 4%, which will provide the most accurate operation of the product in any position of the antenna system.As a result of this work reflector design was developed, created and verified by experimental data calculation model. Reflector antenna device of the DMRL-S was manufactured and tested. The reflector was made of reinforced

    M.A. Ebadian, Ph.D.

    1999-01-01

    The dismantlement of radioactively contaminated process equipment is a major concern during the D&D process. There are an estimated 1,200 buildings in the DOE-EM complex that will require the dismantlement of equipment and various metal structures. As buildings undergo the D&D process, this metallic equipment contaminated with radionuclides such as uranium and plutonium must be size-reduced before final disposal. A single information source comparing dismantlement technologies in the areas of safety, cost, and performance is needed by DOE managers and is not currently available. The selection of the appropriate technologies to meet the dismantlement objectives for a given site is a difficult process in the absence of comprehensive and comparable data. Choosing the wrong technology could result in increased exposure of personnel to contaminants and an increase in D&D project costs. The purpose of this investigation was to evaluate commercially available and innovative technologies for equipment dismantlement and provide a comprehensive source of information to the D&D community in the areas of technology performance, cost, and health and safety.

    Full Text Available South Africa has tried various strategies to improve access, quality and cost-efficiency in the health care delivery systems. However it is clear that the optimal approach has yet to be found. It has been recognised that health technology is an important element of this transformation, and will continue to play a vital role.
    It is almost evident that the way health technology is managed in health care institutions directly affects the quality of treatment patients receive. Although strategic importance of technology in health care has been documented widely in scientific literature; technology planning, procurement and management have not received the attention they deserve in the transformation of health care services in the country.
    The survey discussed in this paper investigated health care equipment maintenance problems and associated technological constraints from point of view of health technology managers, biomedical and clinical engineers. It also provides recommendations for competitive utilisation of technology in the public health sector.

    Directory of Open Access Journals (Sweden)

    V. V. Chugunkov

    2017-01-01

    Full Text Available The environmental conditions of autonomous objects of different-purpose technical complexes are in close relationship with increased values of operating temperatures. This requires thermal pretesting of the process equipment. The publication [1] considers the thermal test conditions in which the equipment elements under test are placed in a heated water tank covered by the globe insulators where, under automatic temperature control using a block of heaters, they are then kept for a specified period of time at a specified temperature range. Such an approach to the thermal tests of equipment allows us to reduce, but not eliminate completely the mass flows of water from evaporation with reducing power consumption of test equipment.Despite the results achieved, even a little bit of water vapor available when conducting the thermal tests may cause a failure of equipment. Therefore, there is a need in test equipment modernization for complete eliminating the fluxes of mass water and better power consumption in the test process. To this end, it is proposed to place a three-layer bubble wrap on the open surface of water.To justify an efficiency of the proposed option was developed a mathematical model of heat and mass transfer processes that occur during thermal tests, taking into account the geometric and thermo-physical characteristics of test tank, polymer film, and equipment. Using the laws and equations of heat and mass transfer enabled us to determine the required capacities for heating the tank with water and equipment to the required temperature range for a specified time, as well as the mass flows of water when evaporating from the tank surface.The efficiency of the three-layer bubble film as compared with the globe insulators as the elements for covering the test tank the surface has been analysed on the basis of the results obtained.The proposed film coating allowed almost complete elimination of evaporation losses of water mass and almost 8

    The aim of this study was to determine the perceptions of nurses who work in critical care units about positive and negative effects related to the use of technological equipment and identify relationships between these perceptions and demographic characteristics of participants. Previous researchers have investigated the perceptions of nursing personnel about the effects of technology on clinical practice. However, most of them focus on specific negative effects. Positive and negative effects have never been studied as a whole. Critical care nurses were surveyed to elicit their perceptions regarding the use of technological equipment. The instrument comprised a 14-item questionnaire and a series of demographic characteristics. A five-point Likert scale was used for each of these 14 questions. The questionnaire was administered to 122 nurses working at the four critical care units of a major academic hospital in Patras, Greece, from 1/10/2003 to 31/12/2003. The completion of the questionnaires was achieved by means of a personal interview. A total of 118 questionnaires were completed. The majority of nurses recognized the positive effects of equipment regarding patient care and clinical practice. At the same time, they agreed that use of equipment possibly leads to increased risk due to human errors or mechanical faults, increased stress and restricted autonomy of nursing personnel. The use of machines does not add to nursing prestige and this may be related to decreased autonomy. Human errors, mechanical faults and increased stress do not seem to come as a result of time constriction but rather of inadequate education. Undergraduate and continuing education should respond efficiently to the needs of contemporary critical care. Recognition of positive and negative effects of machines through the investigation of perceptions of nurses is the first step before looking for ways of maximizing advantages and facing disadvantages of equipment use.

    2014-04-30

    High technology manufacturing equipment is utilized at Los Alamos National Laboratory (LANL) to support nuclear missions. This is undertaken from concept initiation where equipment is designed and then taken through several review phases, working closely with system engineers (SEs) responsible for each of the affected systems or involved disciplines (from gasses to HVAC to structural, etc.). After the design is finalized it moves to procurement and custom fabrication of the equipment and equipment installation, including all of the paperwork involved. Not only are the engineering and manufacturing aspects important, but also the scheduling, financial forecasting, and planning portions that take place initially and are sometimes modified as the project progresses should requirements, changes or additions become necessary. The process required to complete a project of this type, including equipment installation, is unique and involves numerous steps to complete. These processes can be improved and recent work on the Direct Current Arc (DC Arc) Glovebox Design, Fabrication and Installation Project provides an opportunity to identify some important lessons learned (LL) that can be implemented in the future for continued project improvement and success.

    1996-08-01

    The basic concept of active noise control, i. e. to create a noise field in a space in order to destructively interfere with an existing noise, and in the process create a quieter space, was explained. The manner in which noise control technology can be used in air pollution control equipment was described and guidelines for application were provided. A number of case studies were used to illustrate the suitability of active noise control for low frequency noise problems, especially in the area of air pollution control equipment. Impressive reduction of low frequency noise, energy efficiency, ability to retrofit into an existing duct system, and the hardware`s insensitivity to dirty exhaust environments were cited as the principal reasons for the success of active noise control technology over more traditional in-line passive silencers. 1 ref., 8 figs.

    Full Text Available The analysis of possible variants of reconstruction of the power equipment is fulfilled and the conclusion concerning the prospects of such work with the use of composite materials is reached. The data on the technical characteristics of composite repair materials for various purposes are presented, the results of repairs of power equipment, in particular the technology for the recovery of the boarding surfaces of the diffuser rings and protection of the pumps D1250 casings are provided. The technology of the recovery pneumatic cylinder, hydraulic cylinder rod, as well as the unique technology of restoration of working surfaces of the impeller vanes of transfer pump, that had been destroyed by corrosion in conjunction with the cavitation processes and were considered as not restorable is described. The restored impeller was in operation during a year and only thereafter it was removed for restoration. Another composite material discussed in the article – diagum – makes it possible to perform a series of repairs associated with restoration of the rubber-covered surfaces of pump casings as well as with restoration of various surfaces of the conveyor belts. Taking the excellent adhesive properties of this composite into account, restoration of worn stainless steel sieve screens to remove abrasive material was fulfilled with the aid of it. The restoration was accomplished via the use of the conveyor belt which application time had expired, that was glued to a metal sieve with diagum. The use of the composites is economically justified, because the application of them in repairs reduces, firstly, terms of restoration work and, secondly, the price of repairs. Third, equipment that was damaged beyond repair is being commissioned by the use of the mentioned composites.

    Cheng, Hefa; Hu, Yuanan; Reinhard, Martin

    2014-02-18

    With significant water savings and low maintenance requirements, artificial turf is increasingly promoted as a replacement for natural grass on athletic fields and lawns. However, there remains the question of whether it is an environmentally friendly alternative to natural grass. The major concerns stem from the infill material that is typically derived from scrap tires. Tire rubber crumb contains a range of organic contaminants and heavy metals that can volatilize into the air and/or leach into the percolating rainwater, thereby posing a potential risk to the environment and human health. A limited number of studies have shown that the concentrations of volatile and semivolatile organic compounds in the air above artificial turf fields were typically not higher than the local background, while the concentrations of heavy metals and organic contaminants in the field drainages were generally below the respective regulatory limits. Health risk assessment studies suggested that users of artificial turf fields, even professional athletes, were not exposed to elevated risks. Preliminary life cycle assessment suggested that the environmental impacts of artificial turf fields were lower than equivalent grass fields. Areas that need further research to better understand and mitigate the potential negative environmental impacts of artificial turf are identified.

  3. The technology of layer-specific rotary soil cultivation for forest crops and equipment for its implementation

    Directory of Open Access Journals (Sweden)

    S. N. Orlovskiy

    2017-06-01

    Full Text Available Influence of existing methods and technologies of soil processing for forest crops on establishment and growth of cultivated tree species was studied. It was found that furrow plough processing of soil can interfere with the cultivated trees’ ecological peculiarities, because the furrow floor, where trees are planted, often constitutes the lower part of the turf or the upper part of the ashen-gray layers having unfavorable water-physical conditions and decreased crop-producing power. Whenever conifer trees grow on the bottom of a furrow excavated in medium and heavy clay loam, their growth is significantly decreased and accompanied by remarkable changes in morphology. Processing of shallow humus thickness soil with multiple cutter results in mixing of A0, A1 and A2 (ashen-gray layers. Consequently, the processed horizon obtains a lower amount of fertile substances than the vegetable soil on non-processed places. An apparatus for graded soil tillage, its construction, working principle and usage technology are described. The major peculiarity of the device consists in the ability not to crumbl the soil, but to shake down vegetable earth cut by subsurface plow from beneath. The technology involves removing roots and grass outside cultivated land, so that it cannot be then overgrown with weeds. It was found that exploitation of the device improves soil pulverization quality, enhances percentage of separates less than 10 mm and 10–50 mm, decreases content of the separate larger than 50 mm, and reduced specific energy output almost three-fold. Vertical displacement of control particles while soil processing with common cutter machines and the suggested device was studied. Establishment and growth of Siberian pine was determined in experimental productive cultures at different planting technologies. It was shown that under the suggested technology, forest plants furrow sowing can be done while soil processing, so that making nurseries becomes

    Turf battles have always existed in radiology although recently, we have observed an increase in their numbers and sometimes in their virulence. The main reasons for this increase include the relative plethora of physicians especially in industrialized areas, and the rapid progress and development of medical technology and minimally invasive techniques. These turf battles risk interfering with the overall medical costs of local health care systems as they will inevitably lead to an increase in the concentration of complex medical devices controlled by different specialties which, in turn, will lead to an increase in number of invasive and noninvasive, diagnostic and therapeutic examinations. The only way that radiologists can hope to maintain control of today`s techniques will be if they are willing to offer qualitative expertise in their procedures with full clinical, academic and technological backing similar, or superior to that presented by our respective clinical and surgical colleagues. Furthermore,they should be fully involved in the decisional process and actual purchase of the technological equiment of their entire institution. (orig.) With 1 fig., 1 tab., 37 refs.

    The public has recently raised concerns regarding potential human health and environmental risks associated with tire crumb constituents in the artificial turf of football fields. The aim of the present study was to develop an environmental analysis drawing a comparison between artificial turf football fields and urban areas relative to concentrations of particles (PM10 and PM2.5) and related polycyclic aromatic hydrocarbons (PAHs), aromatic hydrocarbons (BTXs), and mutagenicity of organic extracts from PM10 and PM2.5. No significant differences were found between PM10 concentrations at an urban site and on a turf football field, both during warm and in cold seasons, either with or without on-field activity. PM2.5 concentrations were significantly greater at the urban site in the cold season as was the ratio of PM2.5 to PM10. BTXs were significantly greater at urban sites than on turf football fields on both on warm and cold days. The ratio of toluene to benzene (T/B ratio) was always comparable with that of normal urban conditions. The concentration of PAHs on the monitored football fields was comparable with urban levels during the two different sampling periods, and the contribution of PAHs released from the granular material was negligible. PM10 organic extract mutagenicity for artificial turf football fields was greater, whereas PM2.5 organic extract mutagenicity was lower, compared with the urban site studied. However, both organic extract mutagenicity values were comparable with the organic extract mutagenicity reported in the literature for urban sites. On the basis of environmental monitoring, artificial turf football fields present no more exposure risks than the rest of the city.

    Hospitals rely on pagers and ordinary telephones to reach staff members in emergency situations. New telecommunication technologies such as General Packet Radio Service (GPRS), the third generation mobile phone system Universal Mobile Telecommunications System (UMTS), and Wireless Local Area Network (WLAN) might be able to replace hospital pagers if they are electromagnetically compatible with medical devices. In this study, we sought to determine if GPRS, UMTS (Wideband Code Division Multiple Access-Frequency Division Duplex [WCDMA FDD]), and WLAN (IEEE 802.11b) transmitted signals interfere with life-supporting equipment in the intensive care and operating room environment. According to United States standard, ANSI C63.18-1997, laboratory tests were performed on 76 medical devices. In addition, clinical tests during 11 operations and 100 h of intensive care were performed. UMTS and WLAN signals caused little interference. Devices using these technologies can be used safely in critical care areas and during operations, but direct contact between medical devices and wireless communication devices ought to be avoided. In the case of GPRS, at a distance of 50 cm, it caused an older infusion pump to alarm and stop infusing; the pump had to be reset. Also, 10 cases of interference with device displays occurred. GPRS can be used safely at a distance of 1 m. Terminals/cellular phones using these technologies should be allowed without restriction in public areas because the risk of interference is minimal.

  8. Power Saving Strategies and Technologies in Network Equipment Opportunities and Challenges, Risk and Rewards

    2009-01-01

    Drawing from todays best-in-class solutions, we identify power-saving strategies that have succeeded in the past and look forward to new ideas and paradigms. We strongly believe that designing energy-efficient network equipment can be compared to building sports cars, task-oriented, focused and fast. However, unlike track-bound sports cars, ultra-fast and purpose-built silicon yields better energy efficiency when compared to more generic family sedan designs that mitigate go-to-market risks by being the masters of many tasks. Thus, we demonstrate that the best opportunities for power savings come via protocol simplification, best-of-breed technology, and silicon and software optimization, to achieve the least amount of processing necessary to move packets. We also look to the future of networking from a new angle, where energy efficiency and environmental concerns are viewed as fundamental design criteria and forces that need to be harnessed to continually create more powerful networking equipment.

    Endoscopic submucosal dissection (ESD) is widely practiced in Japan and the Eastern World and is rapidly expanding in western countries for the management of early malignancies of the upper and lower gastrointestinal tube. In addition, novel therapeutic applications deriving from ESD have emerged including the treatment of achalasia, of submucosal tumors, of diverticula, of strictures and of reflux disease. An ESD procedure necessitates not only skills and specific training, but also familiarization with a vast spectrum of devices (endoscopes, high-frequency generators and their settings, endoknives, hoods, irrigation devices) and techniques (such as countertraction, artificial ulcer closure), that render the procedure faster, more efficient and safer. This technological article gives an overview on current and novel equipment for an ESD and associated techniques.

  15. Ontology-Based Gap Analysis for Technology Selection: A Knowledge Management Framework for the Support of Equipment Purchasing Processes

    Science.gov (United States)

    Macris, Aristomenis M.; Georgakellos, Dimitrios A.

    Technology selection decisions such as equipment purchasing and supplier selection are decisions of strategic importance to companies. The nature of these decisions usually is complex, unstructured and thus, difficult to be captured in a way that will be efficiently reusable. Knowledge reusability is of paramount importance since it enables users participate actively in process design/redesign activities stimulated by the changing technology selection environment. This paper addresses the technology selection problem through an ontology-based approach that captures and makes reusable the equipment purchasing process and assists in identifying (a) the specifications requested by the users' organization, (b) those offered by various candidate vendors' organizations and (c) in performing specifications gap analysis as a prerequisite for effective and efficient technology selection. This approach has practical appeal, operational simplicity, and the potential for both immediate and long-term strategic impact. An example from the iron and steel industry is also presented to illustrate the approach.

This project, entitled "Removal of Contaminants from Equipment and Debris and Waste Minimization Using the TECHXTRACT â Technology" was conducted under DOE Contract DE-AC21- 96MC33138, administered by the Federal Energy Technology Center. The contract is divided into two phases - a base phase during which bench scale testing was conducted; and an optional phase for a field demonstration of a full-scale system. This report documents the results from the base phase of the contract. The base phase included the following major elements: - Evaluation of the effectiveness of various decontamination options, using both surrogate and radioactively contaminated samples. - Evaluation of various methods for the treatment of the secondary waste streams from the preferred decontamination system(s). - Evaluation of decontamination effectiveness for concrete rubble. - Preliminary engineering design and cost estimation for a full-scale system. - Preliminary economic analysis of the proposed system versus other currently available options for disposition of the materials. Results from the base phase, which are described in the following report, are very positive. Testing has shown that free release requirements and extremely high decontamination factors can be achieved for a variety of materials and radionuclides. Results for concrete rubble decontamination were less conclusive. The bench scale testing has led to the design of two different systems, both based on the TECHXTRACT â chemistry, for potential full-scale demonstration. Based on the preliminary economic analysis, this system compares favorably with currently available commercial options, including disposal.

    This project was initiated by the Department of Energy in response to a request from the HVAC industry for consolidated information about alternative heating and cooling cycles and for objective comparisons of those cycles in space conditioning applications. Twenty-seven different heat pumping technologies are compared on energy use and operating costs using consistent operating conditions and assumptions about component efficiencies for all of them. This report provides a concise summary of the underlying principals of each technology, its advantages and disadvantages, obstacles to commercial development, and economic feasibility. Both positive and negative results in this study are valuable; the fact that many of the cycles investigated are not attractive for space conditioning avoids any additional investment of time or resources in evaluating them for this application. In other cases, negative results in terms of the cost of materials or in cycle efficiencies identify where significant progress needs to be made in order for a cycle to become commercially attractive. Specific conclusions are listed for many of the technologies being promoted as alternatives to electrically-driven vapor compression heat pumps using fluorocarbon refrigerants. Although reverse Rankine cycle heat pumps using hydrocarbons have similar energy use to conventional electric-driven heat pumps, there are no significant energy savings due to the minor differences in estimated steady-state performance; higher costs would be required to accommodate the use of a flammable refrigerant. Magnetic and compressor-driven metal hydride heat pumps may be able to achieve efficiencies comparable to reverse Rankine cycle heat pumps, but they are likely to have much higher life cycle costs because of high costs for materials and peripheral equipment. Both thermoacoustic and thermionic heat pumps could have lower life cycle costs than conventional electric heat pumps because of reduced equipment and

    The occurrence of skin friction related injuries is an issue for artificial turf sports pitches and remains a barrier to their acceptance. The purpose of this study was to evaluate the current industry standard Securisport® Sports Surface Tester that measures skin surface related frictional behaviour of artificial turf. Little research has been published about the device and its efficacy, despite its widespread use as a standard FIFA test instrument. To achieve a range of frictional behaviours, several "third generation" (3G) carpet and infill combinations were investigated; friction time profiles throughout the Securisport rotations were assessed in combination with independent measurements of skin roughness before and after friction testing via 3D surface scanning. The results indicated that carpets without infill had greatest friction (coefficients of friction 0.97-1.20) while those completely filled with sand or rubber had similar and lower values independent of carpet type (coefficient of friction (COF) ≈0.57). Surface roughness of a silicone skin (s-skin) decreased after friction testing, with the largest change on sand infilled surfaces, indicating an "abrasive" polishing effect. The combined data show that the s-skin is damaged in a surface-specific manner, thus the Securisport COF values appear to be a poor measure of the potential for skin abrasion. It is proposed that the change in s-skin roughness improves assessment of the potential for skin damage when players slide on artificial turf.

    In the CIV measurement most spread at present as a means for measuring hardness of the field surface of a natural turf ground, it was elucidated that the ideal range by the official evaluation standard is greatly different from the distribution of measurement results in five large domestic fields. Consequently, in order to examine the validity of the official evaluation standard, measurement was done on various kinds of test surface mainly of natural turf by means of the 'measuring apparatus for hardness of sport surface', an already established technology in evaluating hardness of the surface of athletic facilities, with comparison made with measurement results by an existing evaluation technology such as CIV. Consequently, a range harder than one in the official standard was considered as suitable for soccer. In addition, it revealed that the CIV measurement had a possibility of causing a difference from human sense by the degree of hardness on the field. (translated by NEDO)

    Turfs are widespread assemblages (consisting of microbes and algae) that inhabit reef systems. They are the most abundant benthic component in the Abrolhos reef system (Brazil), representing greater than half the coverage of the entire benthic community. Their presence is associated with a reduction in three-dimensional coral reef complexity and decreases the habitats available for reef biodiversity. Despite their importance, the taxonomic and functional diversity of turfs remain unclear. We performed a metagenomics and pigments profile characterization of turfs from the Abrolhos reefs. Turf microbiome primarily encompassed Proteobacteria (mean 40.57% ± s.d. 10.36, N = 1.548,192), Cyanobacteria (mean 35.04% ± s.d. 15.5, N = 1.337,196), and Bacteroidetes (mean 11.12% ± s.d. 4.25, N = 424,185). Oxygenic and anoxygenic phototrophs, chemolithotrophs, and aerobic anoxygenic phototrophic (AANP) bacteria showed a conserved functional trait of the turf microbiomes. Genes associated with oxygenic photosynthesis, AANP, sulfur cycle (S oxidation, and DMSP consumption), and nitrogen metabolism (N2 fixation, ammonia assimilation, dissimilatory nitrate and nitrite ammonification) were found in the turf microbiomes. Principal component analyses of the most abundant taxa and functions showed that turf microbiomes differ from the other major Abrolhos benthic microbiomes (i.e., corals and rhodoliths) and seawater. Taken together, these features suggest that turfs have a homogeneous functional core across the Abrolhos Bank, which holds diverse microbial guilds when comparing with other benthic organisms.

  4. Magnetic fields and the technology challenges they pose to beam-based equipment: a semiconductor perspective

    Science.gov (United States)

    Esqueda, Vincent; Montoya, Julian A.

    2005-08-01

    As semiconductor devices shrink in size to accommodate faster processing speeds, the need for higher resolution beam-based metrology equipment and beam-based writing equipment will increase. The electron and ion beams used within these types of equipment are sensitive to very small variations in magnetic force applied to the beam. This phenomenon results from changes in Alternating Current (AC) and Direct Current (DC) magnetic flux density at the beam column which causes deflections of the beam that can impact equipment performance. Currently the most sensitive beam-based microscope manufacturers require an ambient magnetic field environment that does not have variations that exceed 0.2 milli-Gauss (mG). Studies have shown that such low levels of magnetic flux density can be extremely difficult to achieve. As examples, scissor lifts, vehicles, metal chairs, and doors moving in time and space under typical use conditions can create distortions in the Earth's magnetic field that can exceed 0.2 mG at the beam column. In addition it is known that changes in the Earth's magnetic field caused by solar flares, earthquakes, and variations in the Earth's core itself all cause changes in the magnetic field that can exceed 0.2 mG. This paper will provide the reader with the basic understanding of the emerging problem, will discuss the environmental and facility level challenges associated in meeting such stringent magnetic field environments, will discuss some of the mitigation techniques used to address the problem, and will close by discussing needs for further research in this area to assure semiconductor and nanotechnology industries are pre-positioned for even more stringent magnetic field environmental requirements.

    Most air pollution monitoring technologies accompany a time-consuming sample treatment process and provides pollution information only for a local area. Thus, they have a critical restriction in monitoring time-dependent pollution variation effectively over the wide range of area both in height and in width. LIDAR (Light detection and ranging) is a new technology to overcome such drawbacks of the existing pollution monitoring technologies and has long been investigated in the advanced countries. The goal of this project is to develop the mobile air pollution monitoring system and to apply the system to the detection of various pollutants, such as ozone, nitrogen dioxide, sulfur dioxide and aerosols.

    Shumilina, I. V.

    Creation of optimal sanitary - hygienic conditions allows to keep health and capacity of the crewmembers work at increase of space flight duration. There is a wide application experience of means, methods and equipment for sanitary - hygienic supply, which were developed and experimentally tested for space flights. However, about 800 kg personal hygiene means (napkins and towels are made with water and delivered with the Earth) are necessary for 3 crewmembers per one year. For long orbital and interplanetary flights (without an opportunity of stocks updating) it is necessary to increase a degree of Life-Support System isolation and optimization of goods turnover. Washing combined with water regeneration system is most perspective for sanitary - hygienic procedures. Therefore, creation of space equipment for washing with sanitary - hygienic water (SHW) regeneration system is especially important. The researches have shown, that to processes, which can be applied for SHW regeneration in space conditions and require insignificant quantity of additional materials (as against sorption), concern membrane methods (reverse osmosis, nanofiltration etc.). Two-step membrane unit for SHW regeneration recovered no less than 85 % of permeate with the organic and inorganic selectivity of 82-95 %. The tests of two-step membrane unit for SHW regeneration carried out on mock up solutions and real SHW, containing detergents really used in space flight conditions. The researches on a substantiation of an opportunity of clothing washing, clothing drying and the estimation of an opportunity of application of various detergents for clothing washing are urgent. The tests of water extraction technology from textile materials are carried out. Is established, that at conditional time of contact 1s, humidity of a leaving air flow from clothing drying unit comes nearer to 100 %. It is necessary to solve the problem for creation of Life-Support System of new generation for long-term space

  15. A global survey of “TURF-reserves”, Territorial Use Rights for Fisheries coupled with marine reserves

    Directory of Open Access Journals (Sweden)

    Jamie C. Afflerbach

    2014-12-01

    Full Text Available Overfishing and degradation of the marine environment continue to plague coastal communities worldwide, with multiple diverse solutions being proposed. Territorial Use Rights for Fisheries (TURFs is a fishery management approach that aligns fishers’ incentives with sustainability, while marine reserves have proven effective for ecosystem protection, and in some cases for fishery enhancement. These two management approaches are often used in isolation, leaving the potential utility of integrating them poorly understood. We examine cases where TURFs and marine reserves have been implemented together to create “TURF-reserves”. We compiled a database of 27 TURF-reserves and collected information on the governance, management, enforcement, fishing practices, fishing rights, regulations, and design attributes for each site. We address several research questions including: what species are managed with TURF-reserves, how are TURF-reserves created and who is involved in the process? Our findings show that the majority of surveyed TURF-reserves arose from previously established TURF systems that target a range of fisheries, and multiple entities play a role in TURF-reserve development and management. We also examine the differences between two TURF-reserve archetypes and find that those developed with a strong history of customary tenure share distinct qualities from those created in a more recently established, government-mandated system.

    A new method for the ultrasonic enhancement of oil recovery from failing wells is described. The technology involves lowering a source of power ultrasound to the bottom of the well either for a short treatment before removal or as a permanent placement for intermittent use. In wells where the permeability is above 20 mD and the porosity is greater than 15% ultrasonic treatment can increase oil production by up to 50% and in some cases even more. For wells of lower permeability and porosity ultrasonic treatment alone is less successful but high production rates can be achieved when ultrasound is applied in conjunction with chemicals. An average productivity increase of nearly 3 fold can be achieved for this type of production well using the combined ultrasound with chemical treatment technology. Copyright © 2013 Elsevier B.V.

    Steadily increasing rates of urbanization have raised concerns about the negative impacts of urban runoff on receiving surface water quality. These concerns have been further amplified by landscaping paradigms that encourage high-input, intensively-managed and mono-culture turf and lawn landscapes. We conducted a watershed-scale assessment of turf management practices on water quality vis-à-vis less-intensive management practices that preserve and enhance more diverse and native vegetation. The study treatments with existing/established vegetation and landscaping practices included turf, urban, forest, meadow, and a mixed site with a professional golf course. Stream water sampling was performed during baseflow and storm events. Highest nutrient (nitrate and total nitrogen) concentrations in runoff were observed for the mixed watershed draining the golf course. In contrast, nutrient concentrations in baseflow from the turf watershed were lower than expected and were comparable to those measured in the surrounding meadow and forest sites. Runoff losses from the turf site may have been minimal due to the optimal quality of management implemented. Total nitrogen concentrations from the turf site increased sharply during the first storms following fertilization, suggesting that despite optimal management there exists a risk for nutrient runoff following fertilization. Dissolved organic carbon (DOC) concentrations from the turf site were elevated and aromatic in content while the mixed watershed site yielded more labile DOM. Overall, this study suggests that turf lawns, when managed properly, pose minimal environmental risk to surrounding surface waters. Based on the results of this study, providing homeowners with increased information regarding best management practices for lawn maintenance may serve as a cost-efficient method for reducing suburban runoff pollution.

    Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made.

    1979-08-01

    Available technology was surveyed as to possible application to more efficient gas-fired comfort heating and water heating in residences. Objectives were (1) to evaluate energy saving modifications and design approaches, including both retrofit and new systems, and (2) to identify RD and D required to bring to the marketplace those concepts that have a reasonable payback period. Over 60 concepts, including both retrofit devices and new designs, were identified on the basis of the study of the technical literature and discussions with various segments of industry. After evaluating each concept on the basis of expected initial cost, energy consumption, and operating cost, those concepts with a reasonably short payback period were considered from the point of view of RD and D needs. A principal recommendation covering several specific concepts was the study of condensing heat-exchanger systems. RD and D was recommended on both mechanical and aerodynamically valved pulse combustors, radiant burners, catalytic systems, heat pipe systems, self-powered heating units, and gas-fired heat pumps. Relative to retrofit concepts, recommendations covered the effects of derating on furnace corrosion and the methodology for predicting savings in individual homes. Need was also indicated for a methodology to optimize sizing of heating units and for data on energy demand requirements for integrated appliances. General recommendations related to systems control analysis, minimum venting requirements, and combustion air requirements in tight homes.

    Uspensky I. A.

    2015-03-01

    Full Text Available An integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ...

    Daniele Accornero

    2012-07-01

    Full Text Available Still today, the issue of safely and efficiently avoiding the atmospheric release of the nano-particles produced by combustion and incineration processes is a critical and open challenge. This study addresses the conception, the technological realization and the first experimental testing of a new device suitable for in-duct filtration and separation of nano particles dispersed into flue-gas streams. The active filtering material is a membrane made from ptfe foil, in origin impermeable but suitable to allow creation, once properly stretched, of an inner texture of permeable micro- and nano-tubes, thus inducing activation of van der Waals effects to the advantage of improved particles’ sticking. The experimental tests confirm attainment of a remarkable filtration capacity, way better than the so-called ‘absolute filters’. Moreover, the filtration material allows to undergo a simple and safe “regeneration cleaning”  process by which the particles can be re-collected off-duct without any filter dismantling.

This integrated system will consist of a series of decontamination baths using the TechXtract{reg_sign} chemical formulas, followed by a waste treatment process that will remove the contaminants from the spent chemicals. Sufficient decontamination will result so that materials can be released without restriction after they have been treated, even those materials that have traditionally been considered to be {open_quotes}undecontaminable.{close_quotes} The secondary liquid waste will then be treated to separate any hazardous and radioactive contaminants, so that the spent chemicals and wastewater can be discharged through conventional, permitted outlets. The TechXtract{reg_sign} technology is a unique process that chemically extracts hazardous contaminants from the surface and substrate of concrete, steel, and other solid materials. This technology has been used successfully to remove contaminants as varied as PCBs, radionuclides, heavy metals, and hazardous organics. The process` advantage over other alternatives is its effectiveness in safe and consistent extraction of subsurface contamination. TechXtract{reg_sign} is a proprietary process developed, owned, and provided by EET, Inc. The objective of the PRDA is to demonstrate on a full-scale basis an economical system for decontaminating equipment and debris, with further treatment of secondary waste streams to minimize waste volumes. Contaminants will be removed from the contaminated items to levels where they can be released for unrestricted use. The entire system will be designed with maximum flexibility and automation in mind.

  15. Persistence of Overseeded Cool-Season Grasses in Bermudagrass Turf

    Directory of Open Access Journals (Sweden)

    Thomas Serensits

    2011-01-01

    Full Text Available Cool-season grass species are commonly overseeded into bermudagrass turf for winter color. When the overseeded grass persists beyond the spring; however, it becomes a weed. The ability of perennial ryegrass, Italian (annual ryegrass, intermediate ryegrass, and hybrid bluegrass to persist in bermudagrass one year after seeding was determined. Perennial ryegrass, intermediate ryegrass, and Italian ryegrass produced acceptable ground cover in the spring after fall seeding. Hybrid bluegrass did not establish well, resulting in unacceptable cover. Perennial ryegrass generally persisted the most one year after seeding, either because of summer survival of plants or because of new germination the following fall. Plant counts one year after seeding were greater in the higher seeding rate treatment compared to the lower seeding treatment rate of perennial ryegrass, suggesting new germination had occurred. Plant counts one year after seeding plots with intermediate ryegrass or Italian ryegrass were attributed primarily to latent germination and not summer survival. Applications of foramsulfuron generally did not prevent overseeded species stand one year after seeding, supporting the conclusion of new germination. Although quality is less with intermediate ryegrass compared to perennial ryegrass, it transitions out easier than perennial ryegrass, resulting in fewer surviving plants one year later.

    Within a financial context of selection inducing either a decrease or a drop of their home research and development expenditures, energy industries companies have succeeded to maintain and even to increase their knowledge production during the last 15 years (1985 - 1998). To understand these apparently paradoxical changes, elements of analysis are looked for within an evolutionary framework, and more specially referring to the related developments to network-firms, user-supplier relationship, and interactive nature of innovation processes. Empirical data are set on granted patents to a sample of the top 15 world largest companies on both sides of operators and equipment suppliers, and for the two industries of oil production and power generation. Interpretation of the results suggests that two dynamics ought to be distinguished. On one side, dynamics of the networks of technological creation is characterized by an upstream going-up of the head of the network towards suppliers. On the other side networks of creation of competitive advantages and bargaining power continues to be based on the operators and their strategies of adaptation to the constraints and opportunities of their institutional, financial and competitive environment.

    Thick and ultra-thick coal seams are main coal seams for high production rate and high efficiency in Chinese coal mines, which accounts for 44%of the total minable coal reserve. A fully mechanized top-coal caving mining method is a main underground coal extraction method for ultra-thick coal seams. The coal extraction technologies for coal seams less than 14 m thick were extensively used in China. However, for coal seams with thickness greater than 14 m, there have been no reported cases in the world for underground mechanical extraction with safe performance, high efficiency and high coal recovery ratio. To deal with this case, China Coal Technology&Engineering Group, Datong Coal Mine Group, and other 15 organizations in China launched a fundamental and big project to develop coal mining technologies and equipment for coal seams with thicknesses greater than 14 m. After the completion of the project, a coal extraction method was developed for top-coal caving with a large mining height, as well as a ground control theory for ultra-thick coal seams. In addition, the mining technology for top-coal caving with a large mining height, the ground support technology for roadway in coal seams with a large cross-section, and the prevention and control technology for gas and fire hazards were developed and applied. Furthermore, a hydraulic support with a mining height of 5.2 m, a shearer with high reliability, and auxiliary equipment were developed and manufactured. Practical implication on the technologies and equipment developed was successfully completed at the No. 8105 coal face in the Tashan coal mine, Datong, China. The major achievements of the project are summarized as follows:1. A top-coal caving method for ultra-thick coal seams is proposed with a cutting height of 5 m and a top-coal caving height of 15 m. A structural mechanical model of overlying strata called cantilever beam-articulated rock beam is established. Based on the model, the load resistance of the

    Pesticide regulation is examined in the context of Health Canada's Pest Management Regulatory Agency's assessment of the chlorophenoxy herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) for turf. 2,4-D is the most common herbicide used to kill weeds in grass.The medical literature does not uniformly indicate harms from herbicides. However, the balance of epidemiological research suggests that 2,4-D can be persuasively linked to cancers, neurological impairment and reproductive problems. These may arise from 2,4-D itself, from breakdown products or dioxin contamination, or from a combination of chemicals.Regulators rely largely on toxicology, but experiments may not replicate exposures from 2,4-D application to lawns because environmental breakdown products (eg, 2,4-dichlorophenol) may not accumulate and selected herbicides are possibly less contaminated. Dioxins are bioaccumulative chemicals that may cause cancer, harm neurological development, impair reproduction, disrupt the endocrine system and alter immune function. No dioxin analyses were submitted to the Pest Management Regulatory Agency, and the principal contaminants of 2,4-D are not among the 17 congeners covered in pesticide regulation. Independent assessment of all dioxins is needed, in tissues and in the environment.The 2,4-D assessment does not approach standards for ethics, rigour or transparency in medical research. Canada needs a stronger regulator for pesticides. Potentially toxic chemicals should not be registered when more benign solutions exist, risks are not clearly quantifiable or potential risks outweigh benefits. Until landscaping pesticides are curtailed nationally, local bylaws and Quebec's Pesticide Code are prudent measures to protect public health. Physicians have a role in public education regarding pesticides.

    Several characterization methods have been developed to investigate the mechanical and structural properties of vertically aligned carbon nanotubes (VACNTs). Establishing analytical models at nanoscale to interpret these properties is complicated due to the nonuniformity and irregularity in quality of as-grown samples.In this paper, we propose a new methodology to investigate the correlation between indentation resistance of multi-wall carbon nanotube (MWCNT) turfs, Raman spectra and the geometrical properties of the turf structure using adaptive neuro-fuzzy phenomenological modeling. This methodology yields a novel approach for modeling at the nanoscale by evaluating the effect of structural morphologies on nanomaterial properties using Raman spectroscopy.

    Alternative stable states have long been thought to exist in natural communities, but direct evidence for their presence and for the environmental switches that cause them has been scarce. Using a combination of greenhouse and field experiments, we investigated the environmental drivers associated with two distinctive herbaceous communities in coastal ecosystems in New Zealand. In a mosaic unrelated to micro-topography, a community dominated largely by native turf species (notably Leptinella dioica, Samolus repens, and Selliera radicans) alternates with vegetation comprising exotic (i.e., nonnative) pasture species (notably Agrostis stolonifera, Holcus lanatus, Lolium perenne, and Trifolium repens). The species of these two communities differ in functional characters related to leaf longevity and growth rate, and occupy soils of differing nitrogen levels. Both spatial and environmental factors influenced the species composition locally. Reciprocal transplants of soil, with and without associated vegetation, showed that a native turf community developed when sward or soil from either community was bounded by turf, and a pasture community developed when sward or soil from either community was surrounded by pasture. In artificial mixed communities in the greenhouse, turf was able to invade the pasture community where the vegetation was clipped to simulate grazing, and also where Trifolium was removed and/or salt spray was applied. The pasture community invaded the turf where Trifolium was present or nitrogen was added. These results were supported by trends in experimentally manipulated field plots, where the amount of turf cover increased when nitrogen was kept low and when salt spray was applied, whereas pasture cover increased in the absence of salt spray. Thus, persistence of the native turf community is dependent on grazing, both directly and via its effect on keeping nitrogen levels low by excluding the exotic, nitrogen-fixing Trifolium, and by exposing the

    1992-04-01

    The respective roles of regular echinoids and scarid fishes in the transformation of turf algae, the main food resource for reef herbivores, were investigated on French Polynesian coral reefs. The role of one species of parrotfish ( Scarus sordidus) was compared with that of four species of echinoids. The degree and ways of degradation of the algal matter were determined by the organic matter percentage, the composition of the sugar fraction, and the concentration and composition of chlorophylltype pigments as assayed by HPLC analysis. Chemical analyses were performed on anterior and posterior intestines for scarids, intestinal contents and faeces for echinoids, and on fresh algal turf as a control of initial food quality. A decrease in mean percentage of organic matter in gut content was observed from intestine (9.7%) to faeces (7%) in sea urchins, but not in parrotfishes. The total sugar fraction decreased from fresh algal turf (32% of total organic matter) to echinoid (28%) to scarid (18%) gut contents. The ratio of insoluble to soluble sugars (I/S ratios) was higher in echinoids (2.6) than in scarid gut contents (1.0). A decrease in the total pigment concentration was measured from fresh algal turf to echinoid and it was found to be even lower in scarid gut contents. Chromatograms showed that the composition of chlorophyll-type pigments in scarid intestines was very similar to fresh algal turf, with a dominance of native forms, mainly chlorophyll a and b. On the contrary, degraded pigment forms dominated in echinoids. The main degraded products were pheophorbides in sea urchins, and chlorophyllides in parrotfishes. These results provided evidence for differentiation in digestive processes occurring in the two types of grazers. Echinoids released higher degraded algal material than did scarids. Thus, these two types of grazers play different roles in the recycling of organic matter on coral reefs.

    In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

  9. Impact of Mars sand on dust on the design of space suits and life support equipment: A technology assessment

    Simonds, Charles H.

    1991-01-01

    Space suits and life support equipment will come in intimate contact with Martian soil as aerosols, wind blown particles and material thrown up by men and equipment on the Martian surface. For purposes of this discussion the soil is assumed to consist of a mixture of cominuted feldspar, pyroxene, olivine, quartz, titanomagnetite and other anhydrous and hydrous iron bearing oxides, clay minerals, scapolite and water soluble chlorides and sulfates. The soil may have photoactivated surfaces that acts as a strong oxidizer with behavior similar to hydrogen peroxide. The existing data about the Mars soil suggests that the dust and sand will require designs analogous to those uses on equipment exposed to salty air and blowing sand and dust. The major design challenges are in developing high performance radiators which can be cleaned after each EVA without degradation, designing seals that are readily cleaned and possibly in selecting materials which will not be degraded by any strong oxidants in the soil. The magnitude of the dust filtration challenge needs careful evaluation in terms of the trade off between fine-particle dust filters with low pressure drop that are either physically large and heavy, like filter baghouses require frequent replacement of filter elements, of low volume high pressure thus power consumption approaches, or washable filters. In the latter, filter elements are cleaned with water, as could the outsides of the space suits in the airlock.

  17. Is genetic engineering ever going to take off in forage, turf and bioenergy crop breeding?

    Science.gov (United States)

    Wang, Zeng-Yu; Brummer, E Charles

    2012-11-01

    Genetic engineering offers the opportunity to generate unique genetic variation that is either absent in the sexually compatible gene pool or has very low heritability. The generation of transgenic plants, coupled with breeding, has led to the production of widely used transgenic cultivars in several major cash crops, such as maize, soybean, cotton and canola. The process for regulatory approval of genetically engineered crops is slow and subject to extensive political interference. The situation in forage grasses and legumes is more complicated. Most widely grown forage, turf and bioenergy species (e.g. tall fescue, perennial ryegrass, switchgrass, alfalfa, white clover) are highly self-incompatible and outcrossing. Compared with inbreeding species, they have a high potential to pass their genes to adjacent plants. A major biosafety concern in these species is pollen-mediated transgene flow. Because human consumption is indirect, risk assessment of transgenic forage, turf and bioenergy species has focused on their environmental or ecological impacts. Although significant progress has been made in genetic modification of these species, commercialization of transgenic cultivars is very limited because of the stringent and costly regulatory requirements. To date, the only transgenic forage crop deregulated in the US is 'Roundup Ready' (RR) alfalfa. The approval process for RR alfalfa was complicated, involving several rounds of regulation, deregulation and re-regulation. Nevertheless, commercialization of RR alfalfa is an important step forward in regulatory approval of a perennial outcrossing forage crop. As additional transgenic forage, turf and bioenergy crops are generated and tested, different strategies have been developed to meet regulatory requirements. Recent progress in risk assessment and deregulation of transgenic forage and turf species is summarized and discussed.

  7. Customer familiarity with new industrial product technology and its influence on adoption: The case of De Beers diamond extraction equipment

    Directory of Open Access Journals (Sweden)

    Nabbie, A.

    2013-05-01

    Full Text Available An investigation was conducted into the influence of industry customers familiarity with new technology on their decisions when purchasing discontinuous industrial products. This was done in the context where the supplier and customer organisations are entities in the same company. Even in this favourable context, continuous products remained successful despite a better solution being available. Literature on this close type of relationship is sparse, mostly because information on such internal processes is generally regarded as competitive. The case investigated was the DebTech division of De Beers, and their experience with products that they design and manufacture for the global diamond mining industry. Product developer and customer data from applicable projects was analysed, and interviews and observations were conducted. The results indicate that familiarity with the product technology favourably influences perceptions of newness, safety, and the ease of integration of a product. Familiarity increases customers propensity to recommend and purchase new-technology products.

  9. Emerging commons within artisanal fisheries. The Chilean territorial use rights in fisheries (TURFs within a broader coastal landscape

    Directory of Open Access Journals (Sweden)

    Gloria L. Gallardo Fernández

    2011-09-01

    Full Text Available Territorial User Rights in Fisheries (TURFs have spread in Chile, since the late 1990s, in the form of commons institutions. TURFs are presented by some scholars as a social-ecological success; by others as showing economic and compliance problems. Studies looking at the material conditions in which fishers produce and reproduce their livelihoods, and in which TURFs emerge, are scarcer. Ostrom’s theory on the commons claims that certain collective action conditions have to be met to become thriving commons institutions. Our hypothesis is that while institutions are moulded by local material conditions, such as geographical location and social embeddedness, these impose challenges and constraints upon fishers influencing TURFs’ long-term viability. How are collective action conditions influenced when the new TURFs commons do not emerge in tabula rasa contexts but in occupied spaces? Do material conditions influence TURFs’ sustainability? This paper set out to explore these conditions. Huentelauquén’s and Guayacán’s TURFs (central-northern Chile were chosen, as they represent two extremes (rural-urban; on private property-on State/municipal property; mainly diver – mainly fisher contexts in which TURFs have emerged. We mainly used Participatory Rural Approach (PRA tools triangulated with other qualitative methods. This study shows that both social embeddedness (private/State lands, and geographical location (rural/urban matter, resulting in different access to the coast for different TURFs, thus determining some important differences between our cases in at least three relevant areas: entrance, social relations between the fishers’ organization (entitled the TURFs and the landowner (private or municipal/State and the existence or absence of fishing and general infrastructure. Competition for space among key actors seems to affect the process of acquiring a TURF as well as the conditions conductive to collective action. TURFs

    Macroalgal assemblages dominated by the turf-forming alga Phyllophora crispa are described in detail for the first time in the Central Mediterranean Sea. This particular form of algal growth, which comprises an upper mixed layer of multiple algal species with a basal stratum formed by entangled thalli of P. crispa, was observed for the first time in 2012 along the promontory of Punta del Lazzaretto (Giglio Island, Italy). In this study, this assemblage was analysed to document the diversity of macroalgae and invertebrate associated communities and assess their distribution along a depth gradient. The algae forming turfs grow directly on the rock at low depth up to 10-15 m depth, while they grow above P. crispa from 15 m to 35 m depth, resulting in luxuriant beds covering up to 100% of the substrate. Multivariate analysis revealed clear differences regarding algae and invertebrate species richness and abundance between shallow and deep strata because of the dominance of Phyllophora crispa at depths greater than 20 m. The long laminal thalli of P. crispa favoured sessile fauna colonization, while the vagile species were principally linked to the architectural complexity of the turf layer created by the P. crispa, which increased the microhabitat diversity and favoured sediment deposition within the turf layer. The complex structures of these turf assemblages and their widespread distribution along the whole coast of the island suggest a well-established condition of the communities linked to the high natural sedimentation rate observed in the area.

    Despite completing accredited resuscitation training, neonatal trainees often feel unprepared to deal with real-life clinical emergencies. High-fidelity simulator (HFS) technology offers the potential of recreating a realistic stressful clinical environment to aid training and evaluation. To date, there are limited data examining the physiological impact of this training modality in comparison to less costly alternatives. The objective of this study was to compare the effects of low-fidelity simulator (LFS) versus HFS technology on performance levels, objective and subjective measures of stress in neonatal trainees. Sixteen neonatal fellows were invited to participate in a prospective randomized study. Subjects were divided into pairs and randomized to LFS or HFS for completion of scenario I. After an interval of 1 month, fellow teams crossed over to complete scenario II using the alternative simulator technology. Technical and non-technical skills were assessed using validated resuscitation scoring tools. Participants recorded subjective stress at sequential time points before and after each simulation. Buccal cortisol was measured at each corresponding time point and comparison between HFS and LFS groups was made. The mean overall resuscitation performance score was 75.8%±10, but there was no difference in performance between HFS and LFS groups. There was also no significant difference in non-technical skills performance between groups. Salivary cortisol increased over the duration of the simulated experience, but there were no differences between the two groups (P=0.001, two-way repeated measures analysis of variance). We also identified changes in subjective measures of stress (P<0.001, analysis of variance) over time, but again there were no differences between groups. Simulated neonatal resuscitations induce a significant stress response in neonatal trainees; however, we were unable to identify any difference in stress measures between HFS and LFS. These

    Like electronic data interchange (EDI), radio frequency identification (RFID) is a logistics tool developed to aid companies in managing their assets efficiently. RFID is used by companies improve shipment tracking, as well as to improve supply chain efficiencies. The technology uses tiny devices called RFID tags or transponders encoded with specific data about shipments. The tag emits a signal that is read by remote control as it passes through a warehouse gate. While RFID is currently used for pallets, it is hoped that the technology will soon be used for individual objects. Web-based systems are now being used to directly trace and monitor shipments as well as to identify potential delays. Schenker International has recently introduced a transportation management system (TMS) for oil and gas clients. The system is a website that manages shipments from purchase order to site delivery, and functions as a forum for all parties to each shipment. It was concluded that use of the TMS allows oil and gas operators to improve planning efficiencies. 1 fig.

    Dobbs, Emily K.; Potter, Daniel A.

    2014-03-01

    With >80 million United States households engaged in lawn and gardening activities, increasing sustainability of lawn care is important. Mowing height is an easily manipulated aspect of lawn management. We tested the hypothesis that elevated mowing of tall fescue lawn grass promotes a larger, more diverse community of arthropod natural enemies which in turn provides stronger biological control services, and the corollary hypothesis that doing so also renders the turf itself less suitable for growth of insect pests. Turf-type tall fescue was mowed low (6.4 cm) or high (10.2 cm) for two growing seasons, natural enemy populations were assessed by vacuum sampling, pitfall traps, and ant baits, and predation and parasitism were evaluated with sentinel prey caterpillars, grubs, and eggs. In addition, foliage-feeding caterpillars and root-feeding scarab grubs were confined in the turf to evaluate their performance. Although some predatory groups (e.g., rove beetles and spiders) were more abundant in high-mowed grass, predation rates were uniformly high because ants, the dominant predators, were similarly abundant regardless of mowing height. Lower canopy temperatures in high-mowed grass were associated with slower growth of grass-feeding caterpillars. Higher lawn mowing reduces fuel consumption and yard waste, and promotes a deep, robust root system that reduces need for water and chemical inputs. Although in this study elevated mowing height did not measurably increase the already-high levels of predation, it did suggest additional ways through which bottom-up effects on insect pest growth might interact with natural enemies to facilitate conservation biological control.

  11. Turf algae-mediated coral damage in coastal reefs of Belize, Central America

    KAUST Repository

    Wild, Christian

    2014-09-16

    Many coral reefs in the Caribbean experienced substantial changes in their benthic community composition during the last decades. This often resulted in phase shifts from scleractinian coral dominance to that by other benthic invertebrate or algae. However, knowledge about how the related role of coral-algae contacts may negatively affect corals is scarce. Therefore, benthic community composition, abundance of algae grazers, and the abundance and character of coral-algae contacts were assessed in situ at 13 Belizean reef sites distributed along a distance gradient to the Belizean mainland (12–70 km): Mesoamerican Barrier Reef (inshore), Turneffe Atoll (inner and outer midshore), and Lighthouse Reef (offshore). In situ surveys revealed significantly higher benthic cover by scleractinian corals at the remote Lighthouse Reef (26–29%) when compared to the other sites (4–19%). The abundance of herbivorous fish and the sea urchin Diadema antillarum significantly increased towards the offshore reef sites, while the occurrence of direct coral-algae contacts consequently increased significantly with decreasing distance to shore. About 60% of these algae contacts were harmful (exhibiting coral tissue damage, pigmentation change, or overgrowth) for corals (mainly genera Orbicella and Agaricia), particularly when filamentous turf algae were involved. These findings provide support to the hypothesis that (turf) algae-mediated coral damage occurs in Belizean coastal, near-shore coral reefs.

  12. Soil Nitrate Monitoring for Turfgrass Sod Farms and Other Turf Areas

    W. Michael Sullivan

    2001-01-01

    Full Text Available Studies with established turf and golf courses have indicated minimal risk of nitrate pollution of groundwater resulting from turfgrass management, but soil nitrate flux in turfgrass sod production farms and golf courses has received less attention. Information about nitrate-N flux at a particular location can be helpful to the sod producer or the golf course manager when efficiently applying N fertilizers and minimizing risk of nitrate pollution. We used an ion exchange resin capsule system to continuously monitor soil nitrate-N fluxes at 12 sites in southern Rhode Island, including turfgrass sod production farms and a low-maintenance environment. Four capsules were placed in the soil at each site and retrieved at intervals coinciding with management and meteorological events to determine nitrate ion accumulation. We found that the golf course green exhibited significantly higher nitrate-N fluxes than the sod farms and the low-maintenance turf. There was significant interaction between sampling date and study site, indicating that seasonal variation in soil nitrate-N fluxes was affected by turfgrass management. The cultural practice of late fall fertilization to stimulate early spring growth in the following year appeared to present some risk of nitrate loss during the winter from the golf course greens in our region. We conclude that site-specific and time-relevant monitoring is needed to produce and manage turfgrasses in an environmentally sound manner.

    2017-04-01

    The detection of pesticides, associated with turfgrass management, in storm runoff and surface waters of urban watersheds has raised concerns regarding their source, potential environmental effects and a need for strategies to reduce their inputs. In previous research we discovered that hollow tine core cultivation (HTCC) was more effective than other management practices for reducing the off-site transport of pesticides with runoff from creeping bentgrass turf managed as a golf course fairway. This was primarily the result of enhanced infiltration and reduced runoff volumes associated with turf managed with hollow tines. In this study we evaluated the addition of verticutting (VC) to HTCC (HTCC+VC) in an attempt to further enhance infiltration and mitigate the off-site transport of pesticides with runoff from managed turf. Overall, greater or equal quantities of pesticides were transported with runoff from plots managed with HTCC+VC compared to HTCC or VC alone. For the pesticides evaluated HTCCtransport of the high mobility pesticides while HTCC=VC=HTCC+VC for the low mobility pesticides. It is likely the addition of VC following HTCC further increased compaction and reduced availability of recently exposed soil sorptive sites produced from the HTCC. Results of this research provides guidance to golf course managers on selection of management practices that assure quality turf while minimizing off-site transport of pesticides, improving pesticide efficacy and the environmental stewardship of managed biological systems.

  16. Effect of light and nutrient availability on the release of dissolved organic carbon (DOC) by Caribbean turf algae.

    Mueller, Benjamin; den Haan, Joost; Visser, Petra M; Vermeij, Mark J A; van Duyl, Fleur C

    2016-03-22

    Turf algae increasingly dominate benthic communities on coral reefs. Given their abundance and high dissolved organic carbon (DOC) release rates, turf algae are considered important contributors to the DOC pool on modern reefs. The release of photosynthetically fixed carbon as DOC generally, but not always, increases with increased light availability. Nutrient availability was proposed as an additional factor to explain these conflicting observations. To address this proposed but untested hypothesis, we documented the interactive contributions of light and nutrient availability on the release of DOC by turf algae. DOC release rates and oxygen production were quantified in incubation experiments at two light levels (full and reduced light) and two nutrient treatments (natural seawater and enriched seawater). In natural seawater, DOC release at full light was four times higher than at reduced light. When nutrients were added, DOC release rates at both light levels were similar to the natural seawater treatment at full light. Our results therefore show that low light in combination with low nutrient availability reduces the release of DOC by turf algae and that light and nutrient availability interactively determine DOC release rates by this important component of Caribbean reef communities.

    The design of a modular SVBR-100 reactor with a lead-bismuth alloy liquid-metal coolant is described. The basic thermal circuit of a power unit built around the SVBR-100 reactor is presented together with the results of its calculation. The gross electrical efficiency of the turbine unit driven by saturated steam at a pressure of 6.7 MPa is estimated at η{el/gr} = 35.5%. Ways for improving the efficiency of this power unit and increasing its power output by applying gas-turbine and combined-cycle technologies are considered. With implementing a combined-cycle power-generating system comprising two GE-6101FA gas-turbine units with a total capacity of 140 MW, it becomes possible to obtain the efficiency of the combined-cycle plant equipped with the SVBR-100 reactor η{el/gr} = 45.39% and its electrical power output equal to 328 MW. The heat-recovery boiler used as part of this power installation generates superheated steam with a temperature of 560°C, due to which there is no need to use a moisture separator/steam reheater in the turbine unit thermal circuit.

    The development of new technological equipment for the implementation of highly effective methods of recovering highly viscous oil from deep reservoirs is an important scientific and technical challenge. Thermal recovery methods are promising approaches to solving the problem. It is necessary to carry out theoretical and experimental research aimed at developing oil-well tubing (OWT) with composite heatinsulating coatings on the basis of basalt and glass fibers. We used the method of finite element analysis in Nastran software, which implements complex scientific and engineering calculations, including the calculation of the stress-strain state of mechanical systems, the solution of problems of heat transfer, the study of nonlinear static, the dynamic transient analysis of frequency characteristics, etc. As a result, we obtained a mathematical model of thermal conductivity which describes the steady-state temperature and changes in the fibrous highly porous material with the heat loss by Stefan-Boltzmann's radiation. It has been performed for the first time using the method of computer modeling in Nastran software environments. The results give grounds for further implementation of the real design of the OWT when implementing thermal methods for increasing the rates of oil production and mitigating environmental impacts.

    The supply of critical metals like gallium, germanium, indium and rare earths elements (REE) is of technological, economic and strategic relevance in the manufacturing of electrical and electronic equipment (EEE). Recycling is one of the key strategies to secure the long-term supply of these metals. The dissipation of the metals related to the low concentrations in the products and to the configuration of the life cycle (short use time, insufficient collection, treatment focusing on the recovery of other materials) creates challenges to achieve efficient recycling. This article assesses the available data and sets priorities for further research aimed at developing solutions to improve the recycling of seven critical metals or metal families (antimony, cobalt, gallium, germanium, indium, REE and tantalum). Twenty-six metal applications were identified for those six metals and the REE family. The criteria used for the assessment are (i) the metal criticality related to strategic and economic issues; (ii) the share of the worldwide mine or refinery production going to EEE manufacturing; (iii) rough estimates of the concentration and the content of the metals in the products; (iv) the accuracy of the data already available; and (v) the occurrence of the application in specific WEEE groups. Eight applications were classified as relevant for further research, including the use of antimony as a flame retardant, gallium and germanium in integrated circuits, rare earths in phosphors and permanent magnets, cobalt in batteries, tantalum capacitors and indium as an indium-tin-oxide transparent conductive layer in flat displays.

    In arid and semi-arid regions, the use of treated wastewater for landscape irrigation is becoming common practice and a significant asset to conserve potable water supplies. Public interest and lack of field-scale data are leading to a concern that compounds found in reuse water could persist in the environment and contaminate groundwater. As part of a larger study, 2-yr experiments were conducted in CA and NV, where reuse water was the primary source of non-ambient water input. A total of 13 compounds were studied, all originating in irrigation water applied to soil covered in turf or left bare. The target compounds included atenolol, atorvastatin, carbamazepine, diazepam, diclofenac, fluoxetine, gemfibrozil, ibuprofen, meprobamate, naproxen, primidone, sulfamethoxazole, triclosan, and trimethoprim. Analytical protocols for all compounds (detection at ng/L range) were established before the study commenced. The goals of the research were to increase available data on the fate and transport of these target compounds in turfgrass/soil systems, and to use these data to assess long-term risk from using water containing these compounds. Experiments conducted at two scales are discussed here: lysimeter-scale and field-scale. At the lysimeter-scale, 24 drainage lysimeters (120 cm thick) were exposed to treated wastewater as an irrigation source. Lysimeters varied by soil type (two types), soil cover (bare- versus turf-covered) and leaching fraction (5% and 25%). Upper and lower boundary conditions were monitored throughout the study. Water samples were collected periodically after water breakthrough. After the study, soil samples were analyzed for compound mass, allowing compound mass balance and removal to be assessed. At the field-scale, passive drain gages (Decagon Devices) were installed in triplicate in fairways at four operational golf courses, one in NV and three in CA, all with histories of using treated wastewater. The gages measure water fluxes through the 60

    The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

This is a quantitative and descriptive study on which was adopted a structured questionnaire with 23 variables divided into four groups (i the awareness level on WEEE, (ii WEEE management, (iii environmental management and (iv profile of companies  which was applied to 20 companies in the IT sector from Natal / RN. Concerning the results, it was observed that companies have experienced a huge number of deficiencies in infrastructure, information and articulation related to reverse logistic, which helps to explain the fact that 65% of the sample believed that customers are little or no interested in solid waste management issues in the company. Also in reference to the waste management, 35% throw away the WEEE  for recycling, providing the waste stream by the secondary markets. In addition, 60% of the sample were included in the group responsible for collecting and treatment of WEEE and 40% of companies have implemented the management plan and / or maintenance. In conclusion, it was observed that some companies are little attentive to the waste law and its impact on their business. Thus, the logistic reverse and the compliance with WEEE management are hampered by lack of WEEE management plans.

    Over the last few decades, a number of reinforcement learning techniques have emerged, and different reinforcement learning-based applications have proliferated. However, such techniques tend to specialize in a particular field. This is an obstacle to their generalization and extrapolation to other areas. Besides, neither the reward-punishment (r-p) learning process nor the convergence of results is fast and efficient enough. To address these obstacles, this research proposes a general reinforcement learning model. This model is independent of input and output types and based on general bioinspired principles that help to speed up the learning process. The model is composed of a perception module based on sensors whose specific perceptions are mapped as perception patterns. In this manner, similar perceptions (even if perceived at different positions in the environment) are accounted for by the same perception pattern. Additionally, the model includes a procedure that statistically associates perception-action pattern pairs depending on the positive or negative results output by executing the respective action in response to a particular perception during the learning process. To do this, the model is fitted with a mechanism that reacts positively or negatively to particular sensory stimuli in order to rate results. The model is supplemented by an action module that can be configured depending on the maneuverability of each specific agent. The model has been applied in the air navigation domain, a field with strong safety restrictions, which led us to implement a simulated system equipped with the proposed model. Accordingly, the perception sensors were based on Automatic Dependent Surveillance-Broadcast (ADS-B) technology, which is described in this paper. The results were quite satisfactory, and it outperformed traditional methods existing in the literature with respect to learning reliability and efficiency.

    Multiple playing surfaces and footwear used in American football warrant a better understanding of relationship between different combinations of turf and footwear. The purpose of this study was to examine effects of shoe and stud types on ground reaction force (GRF) and ankle and knee kinematics of a 180° cut and a single-leg 90° land-cut on synthetic turf. Fourteen recreational football players performed five trials of the 180° cut and 90° land-cut in three shoe conditions: non-studded running shoe, and football shoe with natural and synthetic turf studs. Variables were analyzed with a 3 × 2 (shoe × movement) repeated measures analysis of variance (p < 0.05). Peak vertical GRF (p < 0.001) and loading rate (p < 0.001) were greater during 90° land-cut than 180° cut. For 180° cut, natural turf studs produced smaller peak medial GRFs compared to synthetic turf studs and non-studded shoe (p = 0.012). For land-cut, peak eversion velocity was reduced in running shoes compared to natural (p = 0.016) and synthetic (p = 0.002) turf studs. The 90° land-cut movement resulted in greater peak vertical GRF and loading rate compared to the 180° cut. Overall, increased GRFs in the 90° land-cut movement may increase the chance of injury.

    The invention refers to units designed for extracting minerals by mechanical action on the face by a cutting tool. There is a known drills which includes a pulse device which contains a combustion chamber, cylinder, piston-percussion tool and cutting tool. The combustion chamber and the sub-piston cavity of the cylinder are connected by a channel in which there is a distributor. Its shortcoming is the fact that the pulse device does not guarantee the necessary motion of the actuating mechanism for its velocity and frequency of the shocks on the cutting tool. This reduces the efficiency of the operation and limits the area of application. The purpose of the proposed invention is to improve productivity of the device. This is achieved because the head of the drill is equipped with a 2-piston pulse device which contains 2-combustion chambers, 2 working cylinders, 2 piston percussion instruments, a rod with gas-conducting and connecting channels for interconnection of the sub-piston cavities and combustion chambers of both cylinders. The spent gases of one cylinder are used for closing the combustion chamber of the second cylinder.

  16. Habitat characteristics influence macrofaunal communities in coralline turf more than mesoscale coastal upwelling on the coast of Northern Chile

    2005-04-01

    Rocky shore communities are often influenced by near-shore coastal upwelling. For macrofauna in algal turf, these effects may be caused directly by well-studied bottom-up mechanisms or indirectly via changes in habitat structure provided by algal turf associated high nutrient loads. Here, we investigated possible interactions between upwelling and habitat structure by sampling diverse faunal assemblages in coralline algal turf on seven rocky intertidal shores in northern Chile, ranging from El Cobre [23°17'1″S, 70°31'40″W] to La Lobería [23°03'40″S, 70°33'14″W]. Some of these shores were located adjacent to strong upwelling centers, while others were in areas rarely affected. On each shore, we sampled four (2 × 2 m) sites separated by 15-50 m. In each site, we collected three replicate cores (80 mm in diameter) from which we measured macrofauna greater than 850 μm, biomass of sediment and epiphytes, frond density and average frond length. We used mean water temperature and its variation at 1-1.5 m water depth (below Extreme Low Water Spring, ELWS) to represent local upwelling intensity because long-term data have shown that these variables make excellent indicators for this region. In total, we found 94 macrofaunal taxa in coralline turf, which is almost three times higher than has previously been reported in Chile. Although macrofaunal assemblages varied significantly among shores, there were no patterns to suggest mesoscale variation in upwelling intensity affected either faunal assemblages or local habitat characteristics. In contrast, multivariate and univariate correlations highlighted sediment and frond density as strong determinants of community structure. We therefore conclude that traditionally studied habitat characteristics, such as structural complexity and habitat heterogeneity, have greater influence on faunal assemblages in mat-like habitats on rocky shores than environmental variables associated with mesoscale coastal upwelling.

  17. Feedbacks between vegetation and solifluction processes on hillslopes: a case study of an alpine turf-banked solifluction lobe

    Solifluction is one of the most widespread processes transporting soil on hillslopes in periglacial environments. While periglacial geomorphologists identified climatic and soil parameters as most important factors influencing solifluction, ecologist have long recognized the importance of vegetation and the co-occurrence of certain species and vegetation communities with solifluction processes and landforms. However, the mechanism of vegetation influences on solifluction, as well as feedbacks between solifluction processes and vegetation, which result in specific vegetation organization and specific landforms, e.g., turf-banked solifluction lobes, is only partly understood. The aim of our study is to improve the understanding of feedbacks between vegetation and solifluction processes and landforms by using established and up-to-date methods in a detailed small-scale study on a turf-banked solifluction lobe in the Turtmann glacier forefield (Switzerland). Our objectives are (i) to examine the effects of species composition and vegetation organization on landform properties; (ii) to investigate the effects of landform properties on species composition and vegetation organization and (iii) to evaluate if feedbacks create turf-banked solifluction lobes as biogeomorphic structures. To assess solifluction lobe and vegetation properties, we employed a detailed geomorphic and vegetation mapping (1:50), complemented by an UAV derived high-resolution orthophoto and DEM, and 2D and 3D electrical resistivity tomography (ERT) measurements in combination with soil moisture measurements. Vegetation mapping shows that (i) dwarf shrubs, which through their plant functional traits can act as engineer species, are the main species covering the solifluction lobe. Geomorphic mapping, DEM terrain analyses and 3D ERT indicate that (ii) lobe geomorphometry and material properties (grain size, moisture) strongly influence species distribution and diversity. 2D ERT shows permafrost

  18. Incidence and risk factors for turf toe injuries in intercollegiate football: data from the national collegiate athletic association injury surveillance system.

    Turf toe is the general term for a sprain of the first metatarsophalangeal (MTP) joint complex. Previously attributed to shoe design and artificial turf, the incidence of turf toe injury has been thought to decline with the advent of newer turf designs. However, the current incidence and epidemiology remain unknown as the majority of the literature consists of small series and addresses diagnosis and treatment rather than epidemiology and prevention. We examined data from the NCAA's Injury Surveillance System (ISS) for 5 football seasons (2004-2005 through 2008-2009), including all preseason, regular season, and postseason practice and competition data. The incidence, epidemiology, and risk factors for turf toe injury, defined as injury to the connective tissue of the first MTP joint, plantar plate complex, and/or sesamoid fracture, were determined. The overall incidence of turf toe injuries in NCAA football players was 0.062 per 1000 athlete-exposures (A-Es; 95% CI 0.052, 0.072). Athletes were nearly 14 times more likely to sustain the injury during games compared to practice, with a mean days lost due to injury of 10.1 (7.9, 12.4). Fewer than 2% of turf toe injuries required operative intervention. There was a significantly higher injury rate on third-generation artificial surfaces compared to natural grass (0.087 per 1000 A-E [0.067, 0.11] vs 0.047 per 1000 A-E [0.036, 0.059]). The majority of injuries occurred as a result of contact with the playing surface (35.4%) or contact with another player (32.7%), and running backs and quarterbacks were the most common positions to suffer turf toe injury. Our data suggest a significantly higher incidence of turf toe injuries during games, a greater susceptibility among running backs and quarterbacks, and a significant contribution of playing surface to risk of injury. Though turf toe injuries may be less common that previously reported in elite football players, these injuries warrant appropriate acute and long

    Crustose coralline algae were the prevalent cover among sessile organisms that paved or grew near the substratum, and also the most commonly overgrown species in a giant kelp Macrocystis pyrifera (L.) C.A. Agardh forest located off San Nicolas Island, California. Giant kelp was the largest and most conspicuous species that overgrew large patches of the substrata; overgrowth among turf organisms also appeared common. To determine the effects of giant kelp holdfasts on crustose coralline algae and other turf organisms,'artificial holdfasts' were placed on 0.125-m2 plots for 5, 8 and 12 months. In these treatments, 50?57% of the crustose coralline algae survived. Because these algae also recruited while covered, the total cover (survivorship plus recruitment) differed by only 7?26% from that sampled at the start of the study. The decline of these algae in control plots was similar to that in the treatment plots mostly because of overgrowth by sessile invertebrates. Bryozoans increased markedly on the control plots, whereas 0?12% survived in the treatment plots. Bryozoans and sponges also recruited under the artificial holdfasts. Some arborescent turf algae survived in the 5- and 8-month treatments; articulated coralline algae survived better than did foliose algae. High survival recruitment of crustose coralline algae while overgrown contributed to their prevalence in benthic communities.

    Full Text Available The aim of this research was to evaluate the influence of the mechanical properties of artificial turf systems on soccer players' performance. A battery of perceptive physiological and physical tests were developed on four different structural systems of artificial turf (System 1: Compacted gravel sub-base without elastic layer; System 2: Compacted gravel sub-base with elastic layer; System 3: Asphalt sub-base without elastic layer; System 4: Asphalt sub-base with elastic layer. The sample was composed of 18 soccer players (22.44±1.72 years who typically train and compete on artificial turf. The artificial turf system with less rotational traction (S3 showed higher total time in the Repeated Sprint Ability test in comparison to the systems with intermediate values (49.46±1.75 s vs 47.55±1.82 s (S1 and 47.85±1.59 s (S2; p0.05. The physiological load was similar in all four artificial turf systems. However, players felt more comfortable on the harder and more rigid system (S4; visual analogue scale = 70.83±14.28 than on the softer artificial turf system (S2; visual analogue scale = 54.24±19.63. The lineal regression analysis revealed a significant influence of the mechanical properties of the surface of 16.5%, 15.8% and 7.1% on the mean time of the sprint, the best sprint time and the maximum mean speed in the RSA test respectively. Results suggest a mechanical heterogeneity between the systems of artificial turf which generate differences in the physical performance and in the soccer players' perceptions.

    T-urf13, a well-documented cms-associated gene from maize, has been shown to render methomyl sensitivity to heterologous systems like rice, yeast and bacteria when expressed constitutively. Since these transgenic plants were fertile, it was hypothesized that T-urf13 gene if expressed in anthers may result in male sterility that could be used for hybrid seed production. Hence, this work was aimed at analysing whether T-urf13 gene when expressed in anthers can result in male sterile plants or requires methomyl treatment to cause male sterility (controllable). This is the first report of transformation of tobacco with T-urf13 gene under anther-specific promoter (TA29) with or without mitochondrial targeting sequence. Most of the transgenic plants obtained were fertile; this was surprising as many male sterile plants were expected as T-urf13 gene is a cms associated gene. Our results suggest that it may not be possible to obtain male sterility by expressing URF13 in the anther by itself or by methomyl application.

    2017-05-01

    Full Text Available The purpose of this study was to compare the effect of artificial turf (AT and natural grass (NG on the physical and technical performance of professional soccer players. A total of 17 healthy male soccer players (24.0 ± 4.1 years, height 174 ± 6.1 cm; body weight 73.4 ± 6.3 kg; body fat % 14.2 ± 2.3; VO2max 55.5 ± 5.3 ml/kg/min from a Costa Rican Professional Soccer League club were subjected to different tests in both types of surfaces (technical test, agility test, repeated sprint ability test, and a small-sided game [8 minutes, 32 x 32 meters, 5 vs. 5]. Players were monitored using a GPS in two sessions, separated by 48 hours, during the club’s pre-season. There were no significant differences between the two types of surfaces for the technical, agility, and repeated sprint ability tests. The physiological and kinematic variables analyzed during the small-sided game presented significant differences in average heart rate (NG = 168.5 ± 8.8, AT = 154.8 ± 11.8, p <.001, maximum heart rate (NG = 183.2 ± 8.3, AT = 175.9 ± 10.4, p =.02, body load (NG = 34.3 ± 11.2, AT = 30.5 ± 11.4, p =.03, and total impacts (NG = 230.1 ± 89.5, AT = 194. 8 ± 86.4, p=.03. It is concluded that playing on the natural grass surface caused more impact on physiological and perceived body load in players. In the case of technical variables, it is concluded that there were no statistically significant differences between the two types of surfaces (p <0.05.

  7. Biological responses of the coral Montastraea annularis to the removal of filamentous turf algae.

    Neidy P Cetz-Navarro

    Full Text Available Coral reef degradation increases coral interactions with filamentous turf algae (FTA and macroalgae, which may result in chronic stress for the corals. We evaluated the effects of short (2.5 month and long (10 month periods of FTA removal on tissue thickness (TT, zooxanthellae density (ZD, mitotic index (MI, and concentration of chlorophyll a (Chl a in Montastraea annularis at the beginning and end of gametogenesis. Ramets (individual lobes within a colony consistently surrounded by FTA and ramets surrounded by crustose coralline algae (CCA were used as controls. FTA removal reduced coral stress, indicated by increased TT and ZD and lower MI. The measured effects were similar in magnitude for the short and long periods of algal removal. Ramets were more stressed at the end of gametogenesis compared with the beginning, with lower ZD and Chl a cm(-2, and higher MI. However, it was not possible to distinguish the stress caused by the presence of FTA from that caused by seasonal changes in seawater temperature. Ramets surrounded by CCA showed less stress in comparison with ramets surrounded by FTA: with higher TT, Chl a cm(-2 and ZD, and lower MI values. Coral responses indicated that ramets with FTA suffered the most deleterious effects and contrasted with those measured in ramets surrounded by CCA. According to published studies and our observations, there could be at least six mechanisms associated to FTA in the stress caused to M. annularis by FTA. Owing to the high cover of FTA (in contrast to macroalgae and CCA in the Caribbean, the chronic stress, the overgrowth and mortality that this functional algal group can cause on M. annularis species complex, a further decline of this important reef-building coral in the Caribbean is expected.

    Full Text Available Macroalgae and filamentous turf algae (FTA are abundant on degraded coral reefs, and the reproductive responses of corals may indicate sub-lethal stress under these conditions. The percentage of gametogenic stages (PGS and the maximum diameter of eggs (MDE; or egg size of Orbicella annularis were used to evaluate the effect of long- (7-10 months and short-term (2.5 months FTA removal (treatments T1 and T2, respectively at both the beginning (May and the end (August of gametogenesis. Ramets (individual lobes of a colony surrounded by FTA (T3 or crustose coralline algae (CCA; T4 were used as controls. The removal of FTA enhanced the development of gametes (i.e., a larger and higher percentage of mature gametes (PMG of O. annularis for T1 vs. T3 ramets in May and T1 and T2 vs. T3 ramets in August. Similar values of PGS and MDE between gametes from T3 and T4 in both May and August were unexpected because a previous study had shown that the same ramets of T4 (with higher tissue thickness, chlorophyll a cm-2 and zooxanthellae density and lower mitotic index values were less stressed than ramets of T3. Evaluating coral stress through reproduction can reveal more sensitive responses than other biological parameters; within reproductive metrics, PGS can be a better stress indicator than egg size. The presence of turf algae strongly impacted the development of gametes and egg size (e.g., PMG in ramets with FTA removal increased almost twofold in comparison with ramets surrounded by FTA in August, most likely exerting negative chronic effects in the long run due to the ubiquity and permanence of turf algae in the Caribbean. These algae can be considered a stressor that affects coral sexual reproduction. Although the effects of turf algae on O. annularis are apparently less severe than those of other stressors, the future of this species is uncertain because of the combined impacts of these effects, the decline of O. annularis populations and the almost

  11. Clean Cities Guide to Alternative Fuel Commercial Lawn Equipment (Brochure)

    Energy Technology Data Exchange (ETDEWEB)

    2011-10-01

    Guide explains the different types of alternative fuel commercial mowers and lists the makes and models of the ones available on the market. Turf grass is a fixture of the American landscape and the American economy. It is the nation's largest irrigated crop, covering more than 40 million acres. Legions of lawnmowers care for this expanse during the growing season-up to year-round in the warmest climates. The annual economic impact of the U.S. turf grass industry has been estimated at more than $62 billion. Lawn mowing also contributes to the nation's petroleum consumption and pollutant emissions. Mowers consume 1.2 billion gallons of gasoline annually, about 1% of U.S. motor gasoline consumption. Commercial mowing accounts for about 35% of this total and is the highest-intensity use. Large property owners and mowing companies cut lawns, sports fields, golf courses, parks, roadsides, and other grassy areas for 7 hours per day and consume 900 to 2,000 gallons of fuel annually depending on climate and length of the growing season. In addition to gasoline, commercial mowing consumes more than 100 million gallons of diesel annually. Alternative fuel mowers are one way to reduce the energy and environmental impacts of commercial lawn mowing. They can reduce petroleum use and emissions compared with gasoline- and diesel-fueled mowers. They may also save on fuel and maintenance costs, extend mower life, reduce fuel spillage and fuel theft, and promote a 'green' image. And on ozone alert days, alternative fuel mowers may not be subject to the operational restrictions that gasoline mowers must abide by. To help inform the commercial mowing industry about product options and potential benefits, Clean Cities produced this guide to alternative fuel commercial lawn equipment. Although the guide's focus is on original equipment manufacturer (OEM) mowers, some mowers can be converted to run on alternative fuels. For more information about propane

  12. Determination of Cd, Cr, Hg and Pb in plastics from waste electrical and electronic equipment by inductively coupled plasma mass spectrometry with collision-reaction interface technology.

    A procedure based on the use of a quadrupole inductively coupled plasma-mass spectrometer equipped with a collision-reaction interface (CRI) for control of spectral overlap interferences was developed for simultaneous determination of Cd, Cr, Hg, and Pb in plastics from waste electrical and electronic equipment (WEEE). The injection of H(2) and He (80 and 60 mL min(-1), respectively) into the sampled plasma, colliding and reacting with potentially interfering polyatomic ions, allows interference-free determination of chromium via its isotopes (52)Cr and (53)Cr that are freed from overlap due to the occurrence of (40)Ar(12)C(+), (40)Ar(12)C(1)H(+), (36)S(16)O(+) or (1)H(36)S(16)O(+). Cadmium, Hg and Pb were directly determined via their isotopes (110)Cd, (111)Cd, (112)Cd, (199)Hg, (200)Hg, (201)Hg, (202)Hg, (206)Pb, (207)Pb, and (208)Pb, without using CRI. The CRI can be quickly activated or deactivated before each analyte measurement. Limits of detection for (52)Cr were 0.04 or 0.14 μg L(-1) with He or H(2) injected in CRI. Cadmium and Pb have LODs between 0.02 and 0.08 μg L(-1) and Hg had 0.93-0.98 μg L(-1), without using CRI. Analyte concentrations for samples varied from 16 to 43, 1 to 11, 4 to 12, and 5 to 13 mg kg(-1) for Cr, Cd, Hg and Pb, respectively.

    Climate change could impact strongly on cold-adapted mountain ecosystems, but little is known about its interaction with traditional land-use practices. We used an altitudinal gradient to simulate a year-round warmer and drier climate for semi-natural subalpine grasslands across a landscape of contrasting land-use management. Turf mesocosms from three pasture-woodland land-use types-unwooded pasture, sparsely wooded pasture, and densely wooded pasture-spanning a gradient from high to low management intensity were transplanted downslope to test their resistance to two intensities of climate change. We found strong overall effects of intensive (+4 K) experimental climate change (i.e., warming and reduced precipitation) on plant community structure and function, while moderate (+2 K) climate change did not substantially affect the studied land-use types, thus indicating an ecosystem response threshold to moderate climate perturbation. The individual land-use types were affected differently under the +4 K scenario, with a 60% decrease in aboveground biomass (AGB) in unwooded pasture turfs, a 40% decrease in sparsely wooded pasture turfs, and none in densely wooded ones. Similarly, unwooded pasture turfs experienced a 30% loss of species, advanced (by 30 days) phenological development, and a mid-season senescence due to drought stress, while no such effects were recorded for the other land-use types. The observed contrasting effects of climate change across the pasture-woodland landscape have important implications for future decades. The reduced impact of climate change on wooded pastures as compared to unwooded ones should promote the sustainable land use of wooded pastures by maintaining low management intensity and a sparse forest canopy, which buffer the immediate impacts of climate change on herbaceous vegetation.

    2010-01-01

    The U.S. Geological Survey, in cooperation with a consortium of 19 cities, towns, and villages in Dane County, Wis., undertook a study to compare the capability of rain gardens with different vegetative species and soil types to infiltrate stormwater runoff from the roof of an adjacent structure. Two rain gardens, one planted with turf grass and the other with native prairie species, were constructed side-by-side in 2003 at two locations with different dominant soil types, either sand or clay. Each rain garden was sized to a ratio of approximately 5:1 contributing area to receiving area and to a depth of 0.5 foot. Each rain garden, regardless of vegetation or soil type, was capable of storing and infiltrating most of the runoff over the 5-year study period. Both rain gardens in sand, as well as the prairie rain garden in clay, retained and infiltrated 100 percent of all precipitation and snowmelt events during water years 2004-07. The turf rain garden in clay occasionally had runoff exceed its confining boundaries, but was still able to retain 96 percent of all precipitation and snowmelt events during the same time period. Precipitation intensity and number of antecedent dry days were important variables that influenced when the storage capacity of underlying soils would become saturated, which resulted in pooled water in the rain gardens. Because the rooftop area that drained runoff to each rain garden was approximately five times larger than the area of the rain garden itself, evapotranspiration was a small percentage of the annual water budget. For example, during water year 2005, the maximum evapotranspiration of total influent volume ranged from 21 percent for the turf rain garden in clay to 25 percent for the turf rain garden in sand, and the minimum ranged from 12 percent for the prairie rain garden in clay to 19 percent for the prairie rain garden in sand. Little to no runoff left each rain garden as effluent and a small percentage of runoff returned to the

    2003-01-01

    Recent advancements in ultrasound equipment, technology and capability make the selection of new or replacement equipment a difficult task. It is not uncommon that the sonographers will have different needs and wants from the equipment than do the radiologists. This potential hurdle needs to be addressed in order to arrive at a mutually acceptable selection. Vendors across the board all have very competitive products and they each have that special little "function" or "enhancement" that sets them apart from their competitor. The customer needs to approach the evaluation of the equipment in a very objective manner in order to truly understand not only the differences of each piece of equipment but the actual capability of each piece of equipment. In the end however, it is the individual sonographer that will be utilizing the equipment most of the time and they should have the final say to department management as to which equipment is selected.

    Sports equipment encompasses a gamut of devices used in laboratory, training and competitive contexts and these form the content of this paper. Ergometers range in sophistication from friction braked stationary bicycles to computer controlled simulators which incorporate exercise modes specific to the athletic user. These are now used in training, as experimental devices and in some instances for competition purposes. Training equipment exhibits a similar emphasis on exercise specificity, safety being an important aspect of its use. Design of projectiles for sporting activities has mainly reflected their traditional modes of use, the introduction of synthetic materials having some ergonomics implications. Similarly, materials science and design technology have contributed innovations in equipment for racquet sports and hitting implements. The changes have tended to be associated with availability of new materials for product construction and have implications for safety and skill in the transition to using the new products. Ski equipment design illustrates ergonomics factors in interfacing the performer with the sporting environment and how equipment has progressed by regenerative design processes. Enhancement of performance in some sports must be accompanied by an awareness of safety requirements: where appropriate, risks to participants should be reduced by use of protective clothing and equipment. Enforced validation of protective equipment is recommended to raise safety levels in certain sports and the safety of spectators must not be neglected. Human factors criteria can then be applied in monitoring, officiating and spectating at sporting events.

  20. Cactus, Riparian Habitat, and Turf Grass: Water Budget and Policy Implications of Vegetation Change Under Urban Heat Island and Effluent Irrigation in the Southwest U.S.

    Science.gov (United States)

    Scott, C. A.

    2008-12-01

    This paper assesses the impacts of two urban growth drivers--urban heat island (UHI) and effluent irrigation--on the landscaping vegetation component of water budgets in semi-arid southern Arizona, and has policy significance for other urbanizing regions facing water scarcity. Landscaping irrigation, accounting for up to half of the study area's urban water demand, is influenced by vegetation type, UHI temperature and evapotranspiration, and water type (potable or effluent). Conservation programs that have resulted in widespread adoption of low-flow indoor plumbing fixtures and appliances currently identify irrigation of lawns, trees, and other landscaping as targets to reduce water use. At the same time, however, high water-demand turf grass is expanding on golf courses, public parks, and campuses that are irrigated using effluent that historically has supported riparian corridor habitat. Tucson, Arizona's UHI over 1969-2006 is characterized by a 0.043 degC/yr increase in annual average differences between urban - nonurban minimum temperatures (Tmin). The most pronounced trends in urban Tmin increases are 0.097 degC/yr for the months of March, April, May, and June corresponding to the pre- monsoon period of highest outdoor water demand. The UHI Tmax and reference evapotranspiration trends are less marked but indicate increasing irrigation demand for both residential and public landscaping. Normalized difference vegetation index (NDVI) from Landsat Thematic Mapper for 1984-2005 shows that vegetation, particularly turf on golf courses, is increasing in Tucson's expanding urban fringe but has largely stabilized or is marginally decreasing in the urban core. Regression analysis of NDVI with water use (records only available for 2000-2006) shows mixed results. The tradeoff between water conservation for residential landscaping and expanding turf grass on public landscaping at the cost of riparian corridors is explored from dual water budget and policy perspectives.

  1. Analysis and comparison of modern methods of turf irrigation, verifying the capability of existing information systems through the use of numerical modeling

    2016-04-01

    The automated irrigation of parks and gardens in public areas has become more and more a common practice due to the many benefits it brings in terms of improving the quality of urban green areas. Since this practice requires significant volumes of water, and this becomes increasingly scarce and expensive, it is necessary that the design criteria and use management aim at maximizing the irrigation efficiency. There are conflicting relationship and competition between trees and turf for several reasons. On one hand the different irrigation needs can cause excess water in the root zones of the trees, on the other hand the surface roots of trees and the shade created from the leaves by the dripline (projection line of the canopy) determine an unfavorable area to the growth of the turf because of light factor. It follows that for an optimal design of an irrigation system is necessary to separate the turf areas from trees, with the disadvantage of considerably complicate the geometries of the sprinklers. Each tree or group of trees need to be associated to a not irrigated area. This problem seems not to have a specifically bibliographical evidence, although there are operating standards primarily used to define buffer zones for trees from constructions (British Standard 5837:2005). Ideally, a high number of sprinklers is required to follow the shape of the areas perfectly. Hence, an additional step is necessary to simplify these geometries, identifying a correct scheme for the sprinkler spacing. Such a sequence of geometric operations has been tested on the "Indro Montanelli" park in Milan, obtaining a reduction of the irrigated area of 47% and a water saving of around 30%. We intend to continue the research applying the model to other parks, verifying its applicability in different situations.

Under contract to Marshall Space Flight Center, Midwest Research Institute compiled a handbook consolidating information about commercially available lubricants. The handbook details chemical and physical properties, applications, specifications, test procedures and test data for liquid and solid lubricants. Lake To Lake's plant engineer used the handbook to effect savings in maintenance labor and materials costs by reducing the number of lubricants used on certain equipment. Strict U.S. Department of Agriculture and Food and Drug Administration regulations preclude lubrication changes n production equipment, but the co-op's maintenance chief was able to eliminate seven types of lubricants for ancillary equipment, such as compressors and high pressure pumps. Handbook data enabled him to select comparable but les expensive lubricants in the materials consolidation process, and simplified lubrication schedules and procedures. The handbook is in continuing use as a reference source when a new item of equipment is purchased.

    The gas plant at Kaarstoe was built as part of the Statpipe gas transport system and went on stream in 1985. In 1993 another line was routed from the Sleipner field to carry condensate, and the plant was extended accordingly. Today heavy additional supply- and export lines are under construction, and the plant is extended more than ever. The main role of the factory is to separate the raw gas into commercial products and to pump or ship it to the markets. The site covers a large number of well-known mechanical equipment. This presentation deals with piping, mechanical and structural disciplines. The lifetime of mechanical equipment is often difficult to predict as it depends on many factors, and the subject is complex. Mechanical equipment has been kept in-house, which provides detailed knowledge of the stages from a new to a 14 years old plant. The production regularity has always been very high, as required. The standard of the equipment is well kept, support systems are efficient, and human improvisation is extremely valuable.

  14. Equipment Obsolescence Management Program

    2014-07-01

    Nuclear Power Plant (NPP) Operators are challenged with securing reliable supply channels for safety related equipment due to equipment obsolescence. Many Original Equipment Manufacturers (OEMs) have terminated production of spare parts and product life-cycle support. The average component life cycles are much shorter than the NPP design life, which means that replacement components and parts for the original NPP systems are not available for the complete design life of the NPPs. The lack or scarcity of replacement parts adversely affects plant reliability and ultimately the profitability of the affected NPPs. This problem is further compounded when NPPs pursue license renewal and approval for plant-life extension. A reliable and predictable supply of replacement co components is necessary for NPPs to remain economically competitive and meet regulatory requirements and guidelines. Electrical and I and C components, in particular, have short product life cycles and obsolescence issues must be managed pro actively and not reactively in order to mitigate the risk to the NPP to ensure reliable and economic NPP operation.

  15. Equipment for gas conversion

    Energy Technology Data Exchange (ETDEWEB)

    Tabata, K.; Matsumoto, I.

    1983-01-28

    Equipment is proposed for vapor conversion of hydrocarbons (Uv), possibly in a mixture with air, in order to produce an inorganic gas, which chiefly consists of H2 and COx. It consists of a reaction pipe made of an inorganic refractory ceramic and equipped along the wall circumference with heaters. The reaction pipe is filled with a combined, multilayer catalyst (Kt) carrier, made of gamma-A1203 which in the transverse cross section has a multipore reticular or fibrous structure. Replacement of the traditional steel (St) materials for the walls of the reaction pipe with ceramic materials reduces the output of the hydrocarbon which contaminates the surface (Pv) of the catalyst; the use of a multilayer carrier for the catalyst made of gamma-A1203 with a porous reticular or fibrous structure reduces the pressure losses in the reactor and facilitates the replacement of the spent catalyst. The equipment is designed for vapor conversion of natural gas, C3H8, and vapors of kerosene, naphtha and so on.

    Science.gov (United States)

    Upfal, M

    1992-04-01

    Equipment maintenance workers within the microelectronics industry have opportunities for occupational exposure to a variety of toxic agents. This pilot investigation compares liver enzymes in this population with that of other coworkers. Participants (n = 135) were randomly selected from a medical surveillance program at the manufacturing facility. Nine job categories were examined, including equipment maintenance workers and electronic technicians. Although abnormal liver enzymes were detected among equipment maintenance workers (odds ratio 16.4; P less than .008) and electronic technicians (odds ratio 27; P less than .0005), the numbers of participants were small (n = 8, 10). The data suggest that independent and/or interactive etiologic roles of occupation and alcohol should be further investigated. Early detection of subclinical occupational or recreational hepatotoxicity with appropriate employment of industrial hygiene control technology and/or the reduction of alcohol consumption may provide a means of preventing liver disease.

    Prospective, randomized, controlled single-blind intervention trial. Shock-absorbing insoles (SAIs), compared with usual insoles, were hypothesized to result in larger increases in pressure pain threshold (PPT) after 3 weeks of use. Shock-absorbing insoles can decrease self-reported pain among young soccer players training on artificial turf. However, nothing is known about the underlying changes in pain sensitivity assessed by PPT. Methods Seventy-five players were included from the youth teams of under 15, under 17, and under 19 years of age, playing for the Aalborg Boldspilklub (AaB) professional sports club. After a randomization stratified by team and age, players were divided into 2 groups, one that received SAIs and a control group that used their usual insoles. Assessments were made in both groups after 3 weeks of training on artificial turf (baseline) and 3 weeks later (follow-up). The primary outcome was change in PPTs from baseline to follow-up, with PPTs measured over 13 locations on the plantar surface of the foot, leg, and low back of the nonpreferred kicking leg. A significantly larger increase was found in PPTs from baseline to follow-up for the SAI group compared with the control group (mean difference, 62 kPa; 95% confidence interval [CI]: 40, 85 kPa). The PPTs increased significantly more among the SAI group compared with the control group (Ppressure sensitivity and pain perception.

    Higher ACL injury rates have been recorded in cleats with higher torsional resistance in American football, which warrants better understanding of shoe/stud-dependent joint kinetics. The purpose of this study was to determine differences in knee and ankle kinetics during single-leg land cuts and 180° cuts on synthetic infilled turf while wearing 3 types of shoes. Fourteen recreational football players performed single-leg land cuts and 180° cuts in nonstudded running shoes (RS) and in football shoes with natural (NTS) and synthetic turf studs (STS). Knee and ankle kinetic variables were analyzed with a 3 × 2 (shoe × movement) repeated-measures ANOVA (P < .05). A significant shoe-by-movement interaction was found in loading response peak knee adduction moments, with NTS producing smaller moments compared with both STS and RS only in 180° cuts. Reduced peak negative plantar flexor powers were also found in NTS compared with STS. The single-leg land cut produced greater loading response and push-off peak knee extensor moments, as well as peak negative and positive extensor and plantar flexor powers, but smaller loading peak knee adduction moments and push-off peak ankle eversion moments than 180° cuts. Overall, the STS and 180° cuts resulted in greater frontal plane knee loading and should be monitored for possible increased ACL injury risks.

    1990-09-01

    The nature of the miscellaneous equipment (devices other than permanently installed lighting and those used for space conditioning) in commercial buildings is diverse, comprising a wide variety of devices that are subject to varied patterns of use. This portion of the commercial load is frequently underestimated, and widely hypothesized to be growing. These properties make it a particularly difficult load to characterize for purposes of demand-side management. In the End-Use Load and Consumer Assessment Program (ELCAP), over 100 commercial sites in the Pacific Northwest have been metered at the end-use level for several years. Detailed inspections of the equipment in them have also been conducted. This paper describes how the ELCAP data have been used to estimate three fundamental properties of the various types of equipment in several classes of commercial buildings: (1) the installed capacity per unit floor area, (2) utilization of the equipment relative to the installed capacity, and (3) the resulting energy consumption by building type and for the Pacific Northwest commercial sector as a whole. Applications for the results include assessment of conservation potential, prediction of equipment loads from survey data, estimating equipment loads for energy audits, targeting of conservation technology development, and disaggregating building total or mixed end-use data. 4 tabs., refs.

  13. Soil Carbon and Carbon/Nitrogen Ratio Change under Tree Canopy, Tall Grass, and Turf Grass Areas of Urban Green Space.

    2016-01-01

    Soils in urban green spaces are an important carbon (C) store, but urban soils with a high carbon to nitrogen (C/N) ratio can also buffer N eutrophication from fertilizer use or atmospheric deposition. The influence of vegetation management practices on soil C cycling and C/N ratios in urban green spaces is largely unknown. In 2013, we collected replicate ( = 3) soil samples from tree canopy, tall grass, and short turf grass areas ( = 3) at four random plot locations ( = 4) established in 13 golf courses ( = 13). At each sample point, soil was separated into 0- to 0.1-, 0.1- to 0.2-, and 0.2- to 0.3-m depths (total = 1404). Linear mixed models investigated the relationships between soil properties, vegetation attributes, and green space age. Tree canopy soil was less compacted (1.07 g cm) than grassy areas (1.32 g cm). Similarly, tree canopy soil had mean C/N ratios of 17.2, as compared with between 14.2 and 15.3 in grassy areas. Soil properties in tree canopy areas were best explained by tree basal area and understory vegetation volume. Soil C/N increased with increasing understory vegetation, and the difference in soil C/N between tree canopy and short turf grass areas increased over time. The soil properties in tree canopy areas of urban green space mean they can increasingly buffer the localized use of N fertilizers and atmospheric N deposition. Managers of urban green spaces concerned about N pollution of groundwater and waterways could consider planting trees in suitable topographic locations and promoting understory vegetation and surface litter accumulation.

  14. Urbanisation-related land use change from forest and pasture into turf grass modifies soil nitrogen cycling and increases N2O emissions

    2016-11-01

    Urbanisation is becoming increasingly important in terms of climate change and ecosystem functionality worldwide. We are only beginning to understand how the processes of urbanisation influence ecosystem dynamics, making peri-urban environments more vulnerable to nutrient losses. Brisbane in South East Queensland has the most extensive urban sprawl of all Australian cities. This research estimated the environmental impact of land use change associated with urbanisation by examining soil nitrogen (N) turnover and subsequent nitrous oxide (N2O) emissions using a fully automated system that measured emissions on a sub-daily basis. There was no significant difference in soil N2O emissions between the native dry sclerophyll eucalypt forest and an extensively grazed pasture, wherefrom only low annual emissions were observed amounting to 0.1 and 0.2 kg N2O ha-1 yr-1, respectively. The establishment of a fertilised turf grass lawn increased soil N2O emissions 18-fold (1.8 kg N2O ha-1 yr-1), with highest emissions occurring in the first 2 months after establishment. Once established, the turf grass lawn presented relatively low N2O emissions for the rest of the year, even after fertilisation and rain events. Soil moisture was significantly higher, and mineralised N accumulated in the fallow plots, resulting in the highest N2O emissions (2.8 kg N2O ha-1 yr-1) and significant nitrate (NO3-) losses, with up to 63 kg N ha-1 lost from a single rain event due to reduced plant cover removal. The study concludes that urbanisation processes creating peri-urban ecosystems can greatly modify N cycling and increase the potential for losses in the form of N2O and NO3-.

  15. Direct Liquid Cooling for Electronic Equipment

    Energy Technology Data Exchange (ETDEWEB)

    Coles, Henry; Greenberg, Steve

    2014-03-01

    This report documents a demonstration of an electronic--equipment cooling system in the engineering prototype development stage that can be applied in data centers. The technology provides cooling by bringing a water--based cooling fluid into direct contact with high--heat--generating electronic components. This direct cooling system improves overall data center energy efficiency in three ways: High--heat--generating electronic components are more efficiently cooled directly using water, capturing a large portion of the total electronic equipment heat generated. This captured heat reduces the load on the less--efficient air--based data center room cooling systems. The combination contributes to the overall savings. The power consumption of the electronic equipment internal fans is significantly reduced when equipped with this cooling system. The temperature of the cooling water supplied to the direct cooling system can be much higher than that commonly provided by facility chilled water loops, and therefore can be produced with lower cooling infrastructure energy consumption and possibly compressor-free cooling. Providing opportunities for heat reuse is an additional benefit of this technology. The cooling system can be controlled to produce high return water temperatures while providing adequate component cooling. The demonstration was conducted in a data center located at Lawrence Berkeley National Laboratory in Berkeley, California. Thirty--eight servers equipped with the liquid cooling system and instrumented for energy measurements were placed in a single rack. Two unmodified servers of the same configuration, located in an adjacent rack, were used to provide a baseline. The demonstration characterized the fraction of heat removed by the direct cooling technology, quantified the energy savings for a number of cooling infrastructure scenarios, and provided information that could be used to investigate heat reuse opportunities. Thermal measurement data were used

    In a prior survey, patients with disabilities reported difficulty using many common types of medical equipment. The purpose of this study was to conduct focus groups to explore in greater detail the most common difficulties mentioned by survey participants in order to identify critical issues related to accessibility and usability and to inform subsequent research. Participants of eight focus groups discussed medical equipment accessibility and safety issues experienced when using or attempting to access four specific categories of medical devices: examination tables, imaging equipment, medical chairs, and weight scales. Content of the transcript of each focus group was categorized according to five major themes: safety issues, equipment issues, health care provider issues, patient issues, and environmental issues. The results were then aggregated. The focus group participants reported that characteristics of the equipment's contact surfaces could cause difficulty and discomfort. Participants commented on lack of physical support for patients with disabilities to transfer their bodies onto and off the equipment and lack of support to achieve and maintain body positions while on the equipment. Wheelchair scales were reported as rarely available, and scales without voice output were inaccessible to blind individuals. Health care provider issues and patient issues are discussed in relation to the accessibility and safety of the equipment. Some types of medical devices and technologies present substantial barriers for some medical patients with disabilities, which may negatively affect their access to health care. Recommendations for improved designs are provided to enhance medical equipment accessibility and safety.

    The powder fabrication processes, as the first stage of manufacturing DUPIC (Direct Use of PWR spent fuel In CANDU) fuel, consist of the slitting of spent PWR fuel rods, REOX (Oxidation and REduction of Oxide Fuels) processing to produce the powder feedstock, the milling of the produced powder, the granulation of the milled powder, and the mixing of the granulated powder with pressing lubricants. All these processes should be conducted by remote means in a hot-cell environment where the direct human access is limited to the strictest minimum due to the high radioactivity. This report describe the development of the equipment for fabricating DUPIC fuel powder. These equipment are Slitting Machine, Oxidation and Reduction (OREOX) Furnace, Mill, Roll Compactor, and Mixer. Remote design concept was applied to all the equipment for use in the M6 hot-cell of the IMEF. Mechanical design considerations and capabilities of the equipment for remote operation and maintenance are presented. First prototypes were developed and installed in the DUPIC full scale mock-up and tested using a master-slave manipulator. Redesign and reconstruction were made on each equipment based on mock-up test results. The remote technology acquired through this research was utilized in developing other equipment for DUPIC fuel fabrication, thereby improving safety and increasing productivity. This technology could also be extended to the area of remote handling equipment development for use in hazardous environments. (author). 14 refs., 9 tabs., 21 figs.

    Deficit of air in water causes complications with cyanobacteria mainly in the summer months. Cyanobacteria is a bacteria that produces poison called cyanotoxin. When the concentration of cyanobacteria increases, the phenomena "algal bloom" appears, which is very toxic and may kill all the organisms. This article describes new equipment for aeration of water in dams, ponds and reservoirs with small depth. This equipment is mobile and it is able to work without any human factor because its control is provided by a GPS module. The main part of this equipment consists of a floating pump which pumps water from the surface. Another important part of this equipment is an aerator where water and air are blended. Final aeration process runs in the nozzles which provide movement of all this equipment and aeration of the water. Simulations of the flow are solved by multiphase flow with diffusion in open source program called OpenFOAM. Results will be verified by an experiment.

    Since 2010, numerous new technologies have entered the immunization cold chain equipment market. The World Health Organization (WHO) Immunization Devices Programme-Performance, Quality and Safety (PQS)-has played a key role in bringing these to market. In this article, the authors explore the emergence of new cold chain equipment technologies from 2004 to 2016 and the role of PQS in this evolution. This review focuses on three major vaccine cold chain technology innovations-solar direct-drive refrigerators, long-term passive cold boxes, and equipment with user-independent freeze prevention. For the review, we used online data from WHO PQS, a literature search, and unpublished research reports. Timelines with key milestones in the emergence of the three focus technologies show delays of between one and three years between earliest field trials and publication of WHO specifications; procurement builds after the WHO prequalification of initial devices. The timelines show the role of PQS as both gatekeeper and enabler for cold chain equipment technologies. The use of target product profiles by PQS has increased its ability to signal preferred attributes and to engage with manufacturers during the product-development stage. Procurement data show how demand for solar direct-drive refrigerators increased over time. Gavi, the Vaccine Alliance, is employing demand-generation strategies to try to drive procurement of technologies with favorable technical attributes. Copyright © 2017 The Authors.

  11. Data Network Equipment Energy Use and Savings Potential in Buildings

    Energy Technology Data Exchange (ETDEWEB)

    2010-06-09

    Network connectivity has become nearly ubiquitous, and the energy use of the equipment required for this connectivity is growing. Network equipment consists of devices that primarily switch and route Internet Protocol (IP) packets from a source to a destination, and this category specifically excludes edge devices like PCs, servers and other sources and sinks of IP traffic. This paper presents the results of a study of network equipment energy use and includes case studies of networks in a campus, a medium commercial building, and a typical home. The total energy use of network equipment is the product of the stock of equipment in use, the power of each device, and their usage patterns. This information was gathered from market research reports, broadband market penetration studies, field metering, and interviews with network administrators and service providers. We estimate that network equipment in the USA used 18 TWh, or about 1percent of building electricity, in 2008 and that consumption is expected to grow at roughly 6percent per year to 23 TWh in 2012; world usage in 2008 was 51 TWh. This study shows that office building network switches and residential equipment are the two largest categories of energy use consuming 40percent and 30percent of the total respectively. We estimate potential energy savings for different scenarios using forecasts of equipment stock and energy use, and savings estimates range from 20percent to 50percent based on full market penetration of efficient technologies.

    For centuries, mining has utilized drill and blast as the primary method of rock excavation. Although this technique has undergone significant improvements, it still remains a cyclic, labor intensive operation with inherent safety hazards. Other drawbacks include damage to the surrounding ground, creation of blast vibrations, rough excavation walls resulting in increased ventilation requirements, and the lack of selective mining ability. Perhaps the most important shortcoming of drill and blast is that it is not conducive to full implementation of automation or robotics technologies. Numerous attempts have been made in the past to automate drill and blast operations to remove personnel from the hazardous work environment. Although most of the concepts devised look promising on paper, none of them was found workable on a sustained production basis. In particular, the problem of serious damage to equipment during the blasting cycle could not be resolved regardless of the amount of charge used in excavation. Since drill and blast is not capable of meeting the requirements of a fully automated rock fragmentation method, its role is bound to gradually decrease. Mechanical excavation, in contrast, is highly suitable to automation because it is a continuous process and does not involve any explosives. Many of the basic principles and trends controlling the design of an earth-based mechanical excavator will hold in an extraterrestrial environment such as on the lunar surface. However, the economic and physical limitations for transporting materials to space will require major rethinking of these machines. In concept, then, a lunar mechanical excavator will look and perform significantly different from one designed for use here on earth. This viewgraph presentation gives an overview of such mechanical excavator systems.

    Technology is essential to the delivery of health care but it is still only a tool that needs to be deployed wisely to ensure beneficial outcomes at reasonable costs. Among various categories of health technology, medical equipment has the unique distinction of requiring both high initial investments and costly maintenance during its entire useful life. This characteristic does not, however, imply that medical equipment is more costly than other categories, provided that it is managed properly. The foundation of a sound technology management process is the planning and acquisition of equipment

    1993-09-01

    The combining of miniaturized video technology with thoracoscopy now allows surgeons to perform a variety of thoracic procedures percutaneously. Both rigid and flexible video thoracoscopes are available. The rigid endoscope has a camera located proximally at the eye-piece and is capable of excellent resolution. However, visualization of the entire pleural cavity is difficult because of the rigid chest wall. Placing the video camera at the distal end of a flexible thoracoscope, as in the electronic video thoracoscope (EVE-L; Fujinon, Wayne, NJ), yields better visualization of these relatively inaccessible areas. However, disadvantages of the flexible thoracoscope include increased expense and complexity, reduced resolution as compared to rigid systems, and the need for a strobed light source, thus making video-assisted surgery more difficult. Thoracoscopic wedge excisions of the lung are now possible because of the adaptation of gastrointestinal staplers for percutaneous use. The initial design consisted of a reloadable 30-mm disposable stapler. Newer models, however, have a longer staple line and some are reusable. Future refinements may allow the head of the instrument to articulate, thus permitting it to be applied to the lung at various angles. Thoracoscopic ports that provide an air-tight seal are available but are not essential; therefore, standard thoracotomy instruments can be utilized through small open incisions. Specialized disposable thoracoscopic instruments are also available, including scissors, dissectors, and fan retractors. It is hoped that the future will bring improved optics, better staplers, and refined percutaneous instrumentation.
