  15. Large bulk-yard 3D measurement based on videogrammetry and projected contour aiding

    NASA Astrophysics Data System (ADS)

    Ou, Jianliang; Zhang, Xiaohu; Yuan, Yun; Zhu, Xianwei

    2011-07-01

    Fast and accurate 3D measurement of large stack-yard is important job in bulk load-and-unload and logistics management. Stack-yard holds its special characteristics as: complex and irregular shape, single surface texture and low material reflectivity, thus its 3D measurement is quite difficult to be realized by traditional non-contacting methods, such as LiDAR(LIght Detecting And Ranging) and photogrammetry. Light-section is good at the measurement of small bulk-flow but not suitable for large-scale bulk-yard yet. In the paper, an improved method based on stereo cameras and laser-line projector is proposed. The due theoretical model is composed from such three key points: corresponding point of contour edge matching in stereo imagery based on gradient and epipolar-line constraint, 3D point-set calculating for stereo imagery projected-contour edge with least square adjustment and forward intersection, then the projected 3D-contour reconstructed by RANSAC(RANdom SAmpling Consensus) and contour spatial features from 3D point-set of single contour edge. In this way, stack-yard surface can be scanned easily by the laser-line projector, and certain region's 3D shape can be reconstructed automatically by stereo cameras on an observing position. Experiment proved the proposed method is effective for bulk-yard 3D measurement in fast, automatic, reliable and accurate way.

  4. Large-Scale Variations in Lumber Value Recovery of Yellow Birch and Sugar Maple in Quebec, Canada

    Silvicultural restoration measures have been implemented in the northern hardwoods forests of southern Quebec, Canada, but their financial applicability is often hampered by the depleted state of the resource. To help identify sites most suited for the production of high quality timber, where the potential return on silvicultural investments should be the highest, this study assessed the impact of stand and site characteristics on timber quality in sugar maple (Acer saccharum Marsh.) and yellow birch (Betula alleghaniensis Britt.). For this purpose, lumber value recovery (LVR), an estimate of the summed value of boards contained in a unit volume of round wood, was used as an indicator of timber quality. Predictions of LVR were made for yellow birch and sugar maple trees contained in a network of more than 22000 temporary sample plots across the Province. Next, stand-level variables were selected and models to predict LVR were built using the boosted regression trees method. Finally, the occurrence of spatial clusters was verified by a hotspot analysis. Results showed that in both species LVR was positively correlated with the stand age and structural diversity index, and negatively correlated with the number of merchantable stems. Yellow birch had higher LVR in areas with shallower soils, whereas sugar maple had higher LVR in regions with deeper soils. The hotspot analysis indicated that clusters of high and low LVR exist across the province for both species. Although it remains uncertain to what extent the variability of LVR may result from variations in past management practices or in inherent site quality, we argue that efforts to produce high quality timber should be prioritized in sites where LVR is predicted to be the highest.

  9. Lumber spill in central California waters: implications for oil spills and sea otters

    SciTech Connect

    VanBlaricom, G.R.; Jameson, R.J.

    1982-03-19

    A large quantity of lumber was spilled in the ocean off central California during the winter of 1978, and it spread through most of the range of the threatened California sea otter population within 4 weeks. The movement rates of lumber were similar to those of oil slicks observed elsewhere. These observations indicate that a major oil spill could expose significant numbers of California sea otters to oil contamination.

  3. Pilot and Full Scale Measurements of VOC Emissions from Lumber Drying of Inland Northwest Species

    Volatile organic compounds (VOCs) are precursors to ground level ozone. Ground level ozone is the major component of photochemical smog, and has been linked to a variety of adverse health effects. These health effects include cancer, heart disease, pneumonia and death. In order to reduce ground level ozone, VOC emissions are being more stringently regulated. One VOC source that may come under regulation is lumber drying. Drying lumber is known to emit VOC into the atmosphere. This research evaluates the validity of VOC emission measurements from a small-scale kiln to approximate VOC emissions from kilns at commercial mills. We also report emission factors for three lumber species commonly harvested in the northwest United States (Douglas-fir, ponderosa pine, & grand fir). This work was done with a novel tracer ratio technique at a small laboratory kiln and a large commercial lumber drying facility. The measured emission factors were 0.51 g/kgOD for Douglas-fir, 0.7 g/kgOD for ponderosa pine, and 0.15 g/kgOD for grand fir. Aldehyde emission rates from lumber drying were also measured in some experiments. Results indicate that aldehyde emissions can constitute a significant percentage of the total VOC emissions.

  4. Microbiological degradation of pesticides in yard waste composting.

    PubMed Central

    Fogarty, A M; Tuovinen, O H

    1991-01-01

    Changes in public opinion and legislation have led to the general recognition that solid waste treatment practices must be changed. Solid-waste disposal by landfill is becoming increasingly expensive and regulated and no longer represents a long-term option in view of limited land space and environmental problems. Yard waste, a significant component of municipal solid waste, has previously not been separated from the municipal solid-waste stream. The treatment of municipal solid waste including yard waste must urgently be addressed because disposal via landfill will be prohibited by legislation. Separation of yard waste from municipal solid waste will be mandated in many localities, thus stressing the importance of scrutinizing current composting practices in treating grass clippings, leaves, and other yard residues. Yard waste poses a potential environmental health problem as a result of the widespread use of pesticides in lawn and tree care and the persistence of the residues of these chemicals in plant tissue. Yard waste containing pesticides may present a problem due to the recalcitrant and toxic nature of the pesticide molecules. Current composting processes are based on various modifications of either window systems or in-vessel systems. Both types of processes are ultimately dependent on microbial bioconversions of organic material to innocuous end products. The critical stage of the composting process is the thermophilic phase. The fate and mechanism of removal of pesticides in composting processes is largely unknown and in need of comprehensive analysis. PMID:1886519

  3. Engineered lumber: An alternative to old-growth resources

    SciTech Connect

    Ryan, D. )

    1993-11-01

    People and the environment both have a stake in the future of our forest. Any solution that doesn't consider the two will not resolve the current conflicts such as those occurring in the Pacific Northwest. One answer to the threatened shortage of dimension lumber, and the possibility of reduced harvests in many areas throughout the nation, comes from new-generation technology that can turn logs from young, fast-growing trees into high-quality framing lumber -- the kind that is traditionally obtained from the embattled old-growth forests in the Pacific Northwest. Used primarily in residential construction, [open quotes]engineered lumber[close quotes] is made from strands of wood or veneer generally cut from small-diameter, plentiful trees. High-tech processes bond these wood fibers together with adhesives under heat and pressure to produce structurally engineered lumber. Engineered lumber also has applications in commercial and industrial construction, both as a structural material and as a decorative product. For instance, engineered lumber products were used to create a curved roof truss system on a factory in Austria, while exposed engineered beams adorn the lobbies of office buildings worldwide. Unlike alternative material such as plastic and steel, engineered lumber products are made from a renewable resource and their manufacture consumes far less energy.

  8. Antibiotics, Bacteria, and Antibiotic Resistance Genes: Aerial Transport from Cattle Feed Yards via Particulate Matter

    PubMed Central

    McEachran, Andrew D.; Blackwell, Brett R.; Hanson, J. Delton; Wooten, Kimberly J.; Mayer, Gregory D.; Cox, Stephen B.

    2015-01-01

    Background: Emergence and spread of antibiotic resistance has become a global health threat and is often linked with overuse and misuse of clinical and veterinary chemotherapeutic agents. Modern industrial-scale animal feeding operations rely extensively on veterinary pharmaceuticals, including antibiotics, to augment animal growth. Following excretion, antibiotics are transported through the environment via runoff, leaching, and land application of manure; however, airborne transport from feed yards has not been characterized. Objectives: The goal of this study was to determine the extent to which antibiotics, antibiotic resistance genes (ARG), and ruminant-associated microbes are aerially dispersed via particulate matter (PM) derived from large-scale beef cattle feed yards. Methods: PM was collected downwind and upwind of 10 beef cattle feed yards. After extraction from PM, five veterinary antibiotics were quantified via high-performance liquid chromatography with tandem mass spectrometry, ARG were quantified via targeted quantitative polymerase chain reaction, and microbial community diversity was analyzed via 16S rRNA amplification and sequencing. Results: Airborne PM derived from feed yards facilitated dispersal of several veterinary antibiotics, as well as microbial communities containing ARG. Concentrations of several antibiotics in airborne PM immediately downwind of feed yards ranged from 0.5 to 4.6 μg/g of PM. Microbial communities of PM collected downwind of feed yards were enriched with ruminant-associated taxa and were distinct when compared to upwind PM assemblages. Furthermore, genes encoding resistance to tetracycline antibiotics were significantly more abundant in PM collected downwind of feed yards as compared to upwind. Conclusions: Wind-dispersed PM from feed yards harbors antibiotics, bacteria, and ARGs. Citation: McEachran AD, Blackwell BR, Hanson JD, Wooten KJ, Mayer GD, Cox SB, Smith PN. 2015.

  17. Effect of rotation age on lumber grade, yield, and strength of unthinned loblolly pine

    SciTech Connect

    Clark, A.; McAlister, R.H.; Saucier, J.R.; Reitter, K.

    1996-01-01

    This study examines the effect of rotation age on the grade, yield, and strength of lumber produced from unthinned loblolly pine stands in the coastal plain of Georgia. Six stands representing 22-, 28-, and 40-year rotations were sampled. A stratified random sample of trees with diameters at breast height ranging from 8 to 16 inches was selected from each stand and processed into limber. The strength, yield, and grade of lumber produced increased with increasing rotation age. Based on study data, equations were developed to predict total lumber volume, lumber volume by lumber grade, sawlog stem weight, and cubic volume. Because the yeild of higher grade lumber increased in older trees, the value of lumber produced per cubic foot increased significantly with increasing age. A financial analysis of a simulated plantation harvested at ages ranging from 20 to 40 years illustrates the effects of increasing lumber value and rotation age on net present value of an unthinned loblolly pine stand.

  9. Community Geothermal Technology Program: Experimental lumber drying kiln. Final report

    SciTech Connect

    Leaman, D.; Irwin, B.

    1989-10-01

    Goals were to demonstrate feasibility of using the geothermal waste effluent from the HGP-A well as a heat source for a kiln operation to dry hardwoods, develop drying schedules, and develop automatic systems to monitor/control the geothermally heated lumber dry kiln systems. The feasibility was demonstrated. Lumber was dried in periods of 2 to 6 weeks in the kiln, compared to 18 months air drying and 6--8 weeks using a dehumidified chamber. Larger, plate-type heat exchangers between the primary fluid and water circulation systems may enable the kiln to reach the planned temperatures (180--185 F). However, the King Koa partnership cannot any longer pursue the concept of geothermal lumber kilns.

  10. Noise emissions in wood chipping yards: Options compared.

    PubMed

    Spinelli, Raffaele; Magagnotti, Natascia; Deboli, Roberto; Preti, Christian

    2016-09-01

    Industrial comminution is becoming increasingly popular, as the result of a growing demand for wood biomass. Such task is performed with either chippers or grinders, which are large, powerful machines, capable of generating much noise. In turn, high noise levels may have negative impacts on the health and comfort of workers, and of the people living in the surroundings of a wood fuel yard. This study gauged the difference between the two main technology options (i.e. chippers and grinders) in order to offer additional decision elements to wood yard planners. The chipper on test generated more noise than the grinder, due to its better ability to process wood and to transmit more energy into it. Since the chipper was equipped with less working tools and turned slower than the grinder, it generated its noise peaks at lower frequency bands. The grinder on test was more suitable for use in wood yards located near settled areas, and was an obvious choice whenever dealing with a diversified and occasionally contaminated raw material stream.

  11. Louisiana, Texas fabrication yards on busy upswing

    SciTech Connect

    Pagano, S.S. )

    1994-04-01

    Responding to the continued push to produce natural gas reserves, Texas and Louisiana fabrication yards anticipate a busy 1994 season. Sixty-five oil and gas production platforms are under construction for major companies and independents; total platforms built in 1994 could approach 100. While oil prices are still volatile, most projects are focusing on shallow-water fields. Advanced technology has helped fabricators improve designs by making structures lighter and more cost-effective. PC-Based software helps yards perform more thorough analyses of a structure, which means towers and fixed platforms can be more economically built. Software also enables yards to design cost-effective structures to develop fields with a marginal level of reserves. Several projects currently under development or recently completed are described.

  14. The conservation value of residential yards: linking birds and people.

    PubMed

    Lerman, Susannah B; Warren, Paige S

    2011-06-01

    Urbanization is recognized as one of the greatest threats to biodiversity throughout the world. However, the vegetation within an urbanized landscape is diverse and includes a variety of native and exotic plant species. This variation allows for testing whether certain landscape designs outperform others in the support of native biodiversity. Residential yards represent a large component of an urban landscape and, if managed collectively for birds and other wildlife, could offset some of the negative effects of urbanization. In addition, many urbanites have their primary interaction with the natural world in their front and back yards. Therefore, ensuring positive wildlife experiences for them is essential in promoting urban biodiversity. At the Central Arizona-Phoenix Long-Term Ecological Research site we tested the efficacy of native landscaping in residential yards in attracting native birds. We also explored the links between socioeconomic factors, landscape designs, and urban gradient measurements with the urban bird communities. A redundancy analysis suggested that native desert bird species increased in abundance in neighborhoods with desert landscaping designs, neighborhoods closer to large desert tracts, and higher-income neighborhoods. Variance partitioning showed that collectively these three sets of environmental variables explained almost 50% of the variation in the urban bird community. Results suggested racial and economic inequities in access to biodiversity, whereby predominantly Hispanic and lower-income neighborhoods had fewer native birds. We also found that residents' satisfaction with bird diversity was positively correlated with actual bird diversity. Our study provides new insights into the relative importance of socioeconomic variables and common urban ecological measurements in explaining urban bird communities. Urban planners can use this information to develop residential landscapes that support the well-being of both birds and people

    Kimmitt, R.R.; Davis, E.C.

    1980-01-01

    At the present time the steam plant at the Oak Ridge National Laboratory (ORNL) is undergoing conversion from oil- to coal-fired boilers. To insure that rainwater runoff from the recently constructed coal storage yard meets current discharge standards, a three phase program was initiated. The first phase was a literature review which pointed out the great variability in chemical composition of runoff samples and demonstrated the site-specific nature of the problem. Next, a laboratory treatability study was conducted using samples of runoff from coal identical to that stored on the ORNL yard. In the last phase of the program, data from the study (i.e., chemical dosages, reaction rates, sludge characteristics) were used in the design of a treatment system. The project is currently in the final phase of detailed design.

  17. Different preoperative approaches for acute lumber spinal fractures

    PubMed Central

    Tian, Lu-Feng; Yuan, Yan-Sheng; Li, En-Hui; Wang, Lei

    2015-01-01

    To compare the long and short term effectiveness of different preoperative approaches for lumber spinal fractures and finds a better surgical method for the disease. Follow up records of 144 patients received hyperbaric oxygen therapy or methylprednisolone infusion within 8 hours after the lubmer spinal injury were analyzed. Postoperative outcome immediately and 3, 6, 12, 36 months after the surgery were compared to evaluate the effectiveness two different approaches. The results indicated that there are no significant differences regarding age, sexual proportion, body mass index (BMI), visual analogue scale of pain (VAS) score as well as Frankel scores before the surgery, and significant differences VAS score as well as Frankel scores immediately after the surgery. In conclusion, hyperbaric oxygen therapy within 8 hours after the injury can be more effective than methylprednisolone infusion in patients with lumber spinal injury. PMID:26309686

  4. Evaluation of compost activators for yard waste

    SciTech Connect

    Razvi, A.S.; Kramer, D.W.

    1995-12-31

    The evaluation of the efficiency of yard waste composting (grass clippm`gs/wood chip mixture) was studied for seven commercially available activators, two naturally occurring activators, and one control (absence of activator). The overall decomposition response for each activator was evaluated by comparing four indices of composting efficiency. These were weight loss, change in volume, loss of volatile solids, and oxygen uptake rate. Four experimental blocks were set up in the field, and two experimental blocks were set up in the laboratory. The physical/chemical characteristics were monitored for all samples as a function of time, and individual activators were evaluated so interrelationships between indices could be studied. Based on the four indices, grass clippings can be efficiently composted with natural activators such as Surface Soil or Mature Compost. Commercially available compost activators performed similar to the Control. The cost of commercially available activators was $1.37 to $9.36 per cubic yard of grass clippings to be composted. Naturally occurring activators such as Surface Soil and Mature Compost may be available at no cost to the backyard composter.

  5. Gaseous emissions from outdoor concrete yards used by livestock

    NASA Astrophysics Data System (ADS)

    Misselbrook, T. H.; Webb, J.; Chadwick, D. R.; Ellis, S.; Pain, B. F.

    Measurements of ammonia (NH 3), nitrous oxide (N 2O) and methane (CH 4) were made from 11 outdoor concrete yards used by livestock. Measurements of NH 3 emission were made using the equilibrium concentration technique while closed chambers were used to measure N 2O and CH 4 emissions. Outdoor yards used by livestock proved to be an important source of NH 3 emission. Greatest emission rates were measured from dairy cow feeding yards, with a mean of 690 mg NH 3-N m -2 h -1. Smaller emission rates were measured from sheep handling areas, dairy cow collecting yards, beef feeding yards and a pig loading area, with respective mean emission rates of 440, 280, 220 and 140 mg NH 3-N m -2 h -1. Emission rates of N 2O and CH 4 were much smaller and for CH 4, in particular, emission rates were influenced greatly by the presence or absence of dung on the measurement area.

  6. Back yard blasting on the quiet

    SciTech Connect

    Chironis, N.P.

    1983-06-01

    When R and F Coal Company of Ohio ''sweeps out the corners'' of many of its old sites, it often blasts ''literally in some family's back yard.'' Sequential blasting patterns allow for such work without unduly disturbing the residents. Four basic delay patterns are detailed in this article. Sequential timers, EB caps, HDP blast boosts, and bulk ANFO are used in the sequences. Electric blasting caps can be tested by means of a galvanometer for continuity and resistance whenever possible. The flexibility of programming firing times, in the four patterns, allows operators to fine tune the blasting techniques. End or back break are reduced, fragmentation is optimized, and vibration is held to a minimum.

  7. Microwave Moisture Measurement System for Hardwood Lumber Drying

    SciTech Connect

    Moschler, William W; Hanson, Gregory R

    2008-09-01

    The goal of this project was to develop a prototype microwave-based moisture sensor system suitable for the kiln drying of hardwood lumber. The moisture sensors developed are battery powered and are capable of communicating with a host kiln control system via spread spectrum wireless communications. We have developed two designs of the sensors working at 4.5 to 6 GHz with linear response to moisture content (MC) over a range of 6-100%. These sensors allow us to make a swept frequency microwave transmission measurement through a small area of a board. Using the prototype electronics and sensors, we have obtained measurements of MC over the above MC range for red oak and yellow poplar with standard deviations of less than 1.5% MC. We have developed data for board thickness corrections and for temperature corrections for the MC measurement system.

    Bache, T

    2001-03-30

    In the beginning of the last century there were many accidents in Norwegian forestry, and doctors in the rural districts made great efforts to improve the work environment. District physician Otto Mejlaender (1865-1944) in Trysil was a pioneer. He was actively involved in educational work, wrote articles about the working conditions in the forests and work accidents. The papers refers to various injuries that occurred during work in the forests and how the layman should attend to them. It describes the poor conditions in the lumber cabins, the long and tiresome working day, and the illnesses these activities caused. A summary is also given of an article written by Mejlaender in the Journal of the Norwegian Medical Association in 1906, in which he presents a somewhat unusual case of a young man who damaged his testicles.

  17. Recording and Analysis of the Rec Yard at Alcatraz Island

    NASA Astrophysics Data System (ADS)

    Warden, R.; Toz, T. K.; Everett, M.; DeSmet, T.; Billingsley, A.; Hagin, J.

    2013-07-01

    In the summer of 2012 students and professors from the Concrete Industry Management (CIM ) program at California State University Chico, along with their partners at National Park Service, invited Texas A&M students and professors to join forces and perform a condition assessment of the Recreation Yard at Alcatraz Island in San Francisco Bay. The Recreation Yard is a heavily visited area by tourists who are drawn to the island because of its history as a maximum security prison in the 20th c. Because of its history, first as a military fort in the 19thc., later as a military prison, and finally as a federal prison, many difficult historical and preservation related questions exist. This team was formed to begin research on the historical and preservation questions with respect to the Recreation Yard. This paper and presentation will focus on the integration of documentation technologies employed to aid the research necessary for answering preservation and historical questions regarding the recreations yard. Since that yard was constructed on top of the historic 19th c masonry fort it was requested that we also seek the location of tunnels below the Recreation Yard and their relationship with the walls. Teams were formed to perform Non-destructive testing of concrete walls to determine the size and location of rebar, Ground Penetrating Radar for determining the location of the masonry tunnels and photogrammetry and laser scanning to provide both overall and detailed dimensional information of the current state of material decay.

  18. An assessment of the characteristics of yard trimmings and recirculated yard trimmings used in biowaste composting.

    2010-02-01

    The aim of this research was to characterise samples of yard trimmings (YT) and recirculated yard trimmings (RYT) that are used to co-compost organic fraction of municipal solid waste (OFMSW) taken from 18 composting facilities in Catalonia (NE Spain), to determine their contribution in the composting process, and to highlight the advantages and disadvantages of reusing RYT. We found significant differences between the characteristics of the two materials. RYT had higher pH levels, electrical conductivity, and organic and ammonium nitrogen content than YT. Nutrient content also shows an increment from YT to RYT, and in the case of P and K, this variation can be attributed to an exogenous source rather than the relative concentration during the composting process. We also found significant differences in particle size distribution and bulk density. From the results, it can be assumed that RYT could be reused in the composting process if OFMSW, YT, and RYT are used in the correct quantities to balance the mixture but they cannot totally replace the features of YT.

    Depleted uranium, from US uranium isotope enrichment activities, is stored in the form of solid uranium hexafluoride (UF{sub 6}) in A285 and A516 steel cylinders designed and manufactured to ASME Boiler and Pressure Vessel Code criteria. In general, storage facilities are open areas adjacent to the enrichment plants where the cylinders are exposed to weather. This paper describes the Oak Ridge program to determine the general corrosion behavior of UF{sub 6} cylinders, to determine cylinder yard conditions which are likely to affect long term storage of this material, and to assess cylinder storage yards against these criteria. This program is targeted at conditions specific to the Oak Ridge cylinder yards. Based on (a) determination of the current cylinder yard conditions, (b) determination of rusting behavior in regions of the cylinders showing accelerated attack, (c) monitoring of corrosion rates through periodic measurement of test coupons placed within the cylinder yards, and (d) establishment of a computer base to incorporate and retain these data, the technical division is working with the enrichment sites to implement an upgraded system for storage of this material until such time as it is used or converted.

  1. Experimental Design on Laminated Veneer Lumber Fiber Composite: Surface Enhancement

    NASA Astrophysics Data System (ADS)

    Meekum, U.; Mingmongkol, Y.

    2010-06-01

    Thick laminate veneer lumber(LVL) fibre reinforced composites were constructed from the alternated perpendicularly arrayed of peeled rubber woods. Glass woven was laid in between the layers. Native golden teak veneers were used as faces. In house formulae epoxy was employed as wood adhesive. The hand lay-up laminate was cured at 150° C for 45 mins. The cut specimen was post cured at 80° C for at least 5 hours. The 2k factorial design of experimental(DOE) was used to verify the parameters. Three parameters by mean of silane content in epoxy formulation(A), smoke treatment of rubber wood surface(B) and anti-termite application(C) on the wood surface were analysed. Both low and high levels were further subcategorised into 2 sub-levels. Flexural properties were the main respond obtained. ANOVA analysis of the Pareto chart was engaged. The main effect plot was also testified. The results showed that the interaction between silane quantity and termite treatment is negative effect at high level(AC+). Vice versa, the interaction between silane and smoke treatment was positive significant effect at high level(AB+). According to this research work, the optimal setting to improve the surface adhesion and hence flexural properties enhancement were high level of silane quantity, 15% by weight, high level of smoked wood layers, 8 out of 14 layers, and low anti termite applied wood. The further testes also revealed that the LVL composite had superior properties that the solid woods but slightly inferior in flexibility. The screw withdrawn strength of LVL showed the higher figure than solid wood. It is also better resistance to moisture and termite attack than the rubber wood.

  2. Nde of Lumber and Natural Fiber Based Products with Air Coupled Ultrasound

    NASA Astrophysics Data System (ADS)

    Hsu, David K.; Utrata, David; Kuo, Monlin

    2010-02-01

    Due to the porous nature of wood and natural fiber based products, conventional fluid or gel coupled ultrasonic inspection is unsuitable. Air-coupled ultrasonic transmission scanning, being non-contact, is ideally suited for inspecting lumber, wood and natural fiber based products. We report here several successful applications of air-coupled ultrasound for the inspection of wood. Air-coupled ultrasonic scan at 120 kHz can easily detect "sinker-stock" lumber in which bacterial damage of ray tissue cells had occurred during anaerobic pond storage. Channels in ash lumber board caused by insect bore were imaged in transmission scan. Delamination and material inhomogeneities were mapped out in manufactured wood and natural fiber products including medium density fiberboards, compression molded shredded waste wood with formaldehyde resin, and acoustic panels molded with kenaf fibers. The study has demonstrated some of the capabilities of air-coupled ultrasound in the NDE of forest products.

  3. Lumber recovery from Pacific yew logs: An exploratory study. Forest Service research paper

    Loehnertz, S.P.; Lowell, E.C.; Simpson, W.T.; McDonald, K.A.

    1993-08-01

    In the past several years, thousands of Pacific yew trees were stripped of their bark from which the cancer-fighting compound taxol is obtained. Research has determined that the wood from the Pacific yew does not yield enough taxol to supplement the supply from the bark. Thus, the objectives of this study were to assess the quantity and quality of lumber that could be produced from debarked yew logs. A sample of good quality yew logs were chosen, sawn, edged, and graded, and volume and quality of the lumber were determined. Although the yew logs contained drying splits, spiral grain, and internal decay, and often were fluted and knobby, the lumber produced from these logs is considered attractive and suitable for specialty uses.

    Results from a multi-year study show that a significant part of the extensive variability observed in oriented strand board (OSB) flake dryer emissions can be traced to physiological effects, and the rest can be attributed to handling and other factors. Low-headspace treatment of lumber was scaled up to the 50 kg level. The amount of turpentine collected was of the same magnitude as that released upon drying lumber. For the process to be economical, the wood must first be brought to about 95 C with steam, and then processed with RF. Attempts to remove VOCs from OSB through low-headspace by placing a curtain over the wood failed because of leaks. A more rigid container will be required. RF-treatment does not alter the gas permeability of lumber.

    Anderson, L.M.; Melton, S.G.; Shaw, S.S.

    1993-11-01

    The purpose of the Y-12 Old Salvage Yard scrap metal Characterization Study is to make conservative estimates of the quantities of total uranium and the wt % {sup 235}U contained in scrap metal. The original project scope included estimates of thorium, but due to the insignificant quantities found in the yards, thorium was excluded from further analysis. Metal in three of the four Y-12 scrap metal yards were characterized. The scrap metal yard east of the PIDAS fence is managed by the Environmental Restoration Program and therefore was not included in this study. For all Y-12 Plant scrap metal shipments, Waste Transportation, Storage, and Disposal (WTSD) personnel must complete a Request for Authorization to Ship Nuclear Materials, UCN-16409, which requires the grams of total uranium, the wt % {sup 235}U, and the grams of {sup 235}U contained in the shipment. This information is necessary to ensure compliance with Department of Transportation regulations, as well as to ensure that the receiving facility is adhering to its operating license. This characterization study was designed to provide a technical basis for determining these necessary radioactive quantities.

  19. Global trade, local impacts: lessons from California on health impacts and environmental justice concerns for residents living near freight rail yards.

    Global trade has increased nearly 100-fold since 1950, according to the World Trade Organization. Today, major changes in trade are occurring with the advent of mega-ships that can transport thousands more containers than cargo ships now in use. Because global trade is expected to increase dramatically, the railroad industry-in the U.S. alone-has invested more than $5 billion a year over the past decade to expand rail yards and enhance rail routes to transport goods from ports to retail destinations. This article describes cancer risks for residents living in close proximity to rail yards with emissions of diesel particulate matter pollution from locomotives, trucks and yard equipment. The article examines the demographics (income, race/ethnicity) of populations living in the highest estimated cancer risk zones near 18 major rail yards in California, concluding that the majority are over-represented by either lower-income or minority residents (or both). The authors also describe a review of the news media and environmental impact reports to determine if rail yards are still being constructed or expanded in close proximity to homes and schools or in working class/working poor communities of color. The paper suggests policy efforts that might provide more public health protection and result in more "environmentally just" siting of rail yards. The authors conclude that diesel pollution from rail yards, which creates significant diesel cancer risks for those living near the facilities, is an often overlooked public health, health disparities and environmental justice issue in the U.S. The conclusions are relevant to other countries where international trade is increasing and large new intermodal rail facilities are being considered.

    The article analyzes the present volume measuring and mapping system used for coal yard, and presents a principle which connects phase-modulating laser ranging with high- accurate angle scanning, to fulfill an effective system of measuring and mapping the volume of heaps of coal. This system can complete shape-mapping and volume-measuring over 200 m X 50 m coal yard within 20 minute, and the accuracy up to 0.5%. Also, some detail working principle, actual measuring result and performance analysis of the system are discussed in this article. Due to having solved the prompt (< 1/500) and accurate (3 cm) ranging problem under the condition of low-reflection objects ((rho) < 0.01), this system can be widely used for 3D measuring and mapping on bulky objects.

    Community groups and local air pollution control agencies have identified the San Bernardino Railyard (SBR) as a significant public health and environmental justice issue. In response, the authors conducted a comprehensive study with community members living in close proximity to the rail yard. The purpose of this article is to share the community's perceptions about the rail yard and ideas on sustainable change. A qualitative study using key informant interviews and focus group discussions was conducted and resulted in four emerging themes. Themes emerged as follows: "health as an unattainable value," "air quality challenges," "rail yard pros and cons," and "violence and unemployment ripple effect." Community participants expressed concern for poor air quality, but other challenges took priority. The authors' findings suggest that future mitigation work to reduce air pollution exposure should not only focus on reducing risk from air pollution but address significant co-occurring community challenges. A "Health in All Policies" approach is warranted in addressing impacted communities in close proximity to the goods movement industry. PMID:25226779

  18. American black bears and bee yard depredation at Okefenokee Swamp, Georgia

    We studied American black bears (Ursus americanus), on the northwest periphery of Okefenokee Swamp in southeast Georgia, to assess landowner attitudes toward bears, estimate the extent of damage to commercial honey bee operations by bears, and evaluate methods to reduce bear depredations to apiaries. We collected 8,351 black bear radiolocations and identified 51 bee yards on our study area. Twenty-seven of 43 home ranges contained ≥1 bee yard, averaging 11.3 and 5.1 bee yards/home range of males (n = 7) and females (n = 20), respectively. From 1996 to 1998, we documented 7 instances of bears raiding bee yards within our study area and 6 instances in adjacent areas. All but 1 of the 13 raided yards were enclosed by electric fencing. In the 12 cases of damage to electrically fenced yards, however, the fences were not active because of depleted batteries. Based on compositional analysis, bear use of areas 800–1,400 m from bee yards was disproportionately greater than use 0–800 m from bee yards. Bears disproportionately used bay (red bay: Persea borbonia, loblolly bay: Gordonia lasianthus, and southern magnolia: Magnolia virginia), gum (water tupelo: Nyssa aquatic and black gum: N. sylvatica), and cypress (Taxodium spp.) and loblolly bay habitats, however, compared with slash pine (Pinus elliottii) or pine–oak (Quercus spp.), where bee yards usually were placed. The distribution of bear radiolocations likely reflected the use of those swamp and riparian areas, rather than avoidance of bee yards. Distances to streams from damaged bee yards (x̄ = 1,750 m) were less than from undamaged yards (x̄ = 4,442 m), and damaged bee yards were closer to unimproved roads (x̄ = 134 m) than were undamaged bee yards (x̄ = 802 m). Our analysis suggests that bee yard placement away from bear travel routes (such as streams and unimproved roads) can reduce bear depredation problems. Our results strongly indicate that working electric fences are effective deterrents to bear

    To compare the long and short term effectiveness and complications of different surgical approaches for Lumber disk protrusion combined with Cauda Equina Syndrome and find a better surgical method for the disease. In this study, follow up records of 144 patients received conventional laminectomy and minimally invasive decompression and fenestration 48 hours within acute injury of lumber disk protrusion combined with Cauda Equina Syndrome were analyzed. Surgical outcome immediately and 3, 6, 12, 36 months after the surgery were compared to evaluate the effectiveness two different approaches. The results indicated that there are no significant differences regarding age, sexual proportion, body mass index (BMI), visual analogue scale of pain (VAS) score as well as Frankel scores before the surgery, and significant differences VAS score as well as Frankel scores immediately after the surgery. In conclusion, minimally invasive decompression and fenestration can be of the same effectiveness and less complications comparing with the conventional laminectomy. PMID:25674258

    Studies on the removal of volatile organic compounds (VOC) from wood or wood products were conducted. Steam-induced extraction of VOC from oriented strand board (OSB) was studied using a tube furnace at 130 C which resulted in over 50% removal in 30 minutes. RF treatment of softwood lumber removed up to 68% of VOC in 20 minutes. Studies on the transport of moisture in wood confirmed that transport is greatest in the transverse surface, followed by the tangential and radial faces.

  1. Effects of soil type, irrigation volume and plant species on treatment of log yard run-off in lysimeters.

    2004-09-01

    Wet storage of timber and pulpwood produces large quantities of run-off water. A study was conducted to determine the purification efficiency of soil-plant systems for log yard run-off. Sixteen 1200-l lysimeters (1.2 m deep soil columns) with clay or sand soil were planted with willow (Salix sp.) or alder (Alnus glutinosa), and irrigated with run-off from a Norway spruce (Picea abies) log yard. Drainage water was analysed for total organic carbon (TOC), phenols, total P and total N in order to determine concentrations and levels of retention. High retention of TOC, phenols and P occurred in the lysimeters, but no clear differences between willows and alder or clay and sand were identified. Lysimeters with high levels of irrigation showed greater retention than those with low levels. Soil-plant systems using willow and alder could provide an alternative for log yard run-off purification: the key requirement is to optimise irrigation rather than manipulate the plants or soils.

    For years the Division of Radiation Protection (DRP) has participated in exercises, which are required by the Federal Emergency Management Agency (FEMA) to demonstrate our ability to deal with an accident at a nuclear power plant. These demonstrations are defined by objectives and are structured such that they offer little opportunity to practice for real-world radiological events in the exercise. Since real-world radiological incidents do occur throughout the year, this exercise was designed to be as realistic as possible. A scrap yard incident was chosen as the most probable type of event. The exercise was conducted on May 5 and 6, 1999. PMID:11197512

  3. Wealth distribution under Yard-Sale exchange with proportional taxes

    NASA Astrophysics Data System (ADS)

    Bustos-Guajardo, R.; Moukarzel, Cristian F.

    2016-03-01

    Recent analysis of a Yard-Sale (YS) exchange model supplemented with redistributive proportional taxation suggested an asymptotic behavior P(w)˜1/wμ for the wealth distribution, with a parameter-dependent exponent μ. Revisiting this problem, it is here shown analytically, and confirmed by extensive numerical simulation, that the asymptotic behavior of P(w) is not power-law but rather a Gaussian. When taxation is weak, we furthermore show that a restricted-range power-law behavior appears for wealths around the mean value. The corresponding power-law exponent equals 3/2 when the return distribution has zero mean.

    The results of an investigation conducted to compare the efficiency of sludge from biogas plants with farm-yard manure are reported. With regard to nutrient content, the sludge is seen to have a higher content of moisture, nitrogen, P/sub 2/O/sub 5/, K/sub 2/O and organic carbon, as well as a higher N/C ratio. Both materials were used to fertilize fields of potato and ragi. The yield for potato fertilized with sludge increased by 6% while that for ragi increased by 17%.

    Summary The prevalence rate of low back pain in a number of studies ranged from 22% to 65% in one year, and lifetime prevalence ranged from 11% to 84%. Over the years many percutaneous minimally invasive therapeutic modalities have evolved. Intradiscal oxygen-ozone therapy has also showed promising results. We undertook a prospective cohort study to evaluate the therapeutic outcome of oxygen-ozone therapy on patients with lumber disc herniation in the Indian population. After obtaining ethical committee and investigational review board permission, 53 consecutive patients complying with selection criteria were treated with a single session of oxygen-ozone therapy. All presented with clinical signs of lumber nerve root compression supported by CT and MRI findings. All patients received 3-7 ml of ozone-oxygen mixture at an ozone concentration of29-32 mc/ml of oxygen. Therapeutic outcome was assessed after three weeks, three months, six months, one year and two years on a visual analog scale and Oswestry low back pain disability questionnaire. Pain intensity was significantly reduced following treatment (VAS baseline 7.58±0.86, after three weeks 2.75 ±1.42 and after two years 2.64±2.14). Similarly the Oswestry disability index showed a remarkable improvement in the functional status of the patients (p<0.05). No major complication was observed in this case series. Oxygen-ozone treatment is highly effective in relieving low back pain due to lumber disc herniation. PMID:20465917

    This progress report summarizes three accomplishments in a study of low volatile organic compound (VOC) drying of lumber and wood panel products. A mathematical model for predicting moisture emissions from particle was constructed and is being extended to VOCs. VOCs emissions from drying boards show that VOCs appear to be evenly released from all surfaces. Preliminary results from monthly analyses of loblolly pines indicate that resin acids appear to decrease between March to August, and that no consistent trends are apparent for terpenes. 3 refs., 13 figs., 1 tab.

    This study examined some physical characteristics of laminated veneer lumber (LVL) obtained in different compositions from cut veneers of Oriental beech (Fagus Orientalis Lipsky) and Lombardy poplar (Populus nigra) with thicknesses of 4 mm and 5 mm. Five each beech and poplar trees were felled with this objective. The PVAc (Kleiberit 303) and PU (Bizon Timber PU-Max Express) types of adhesive were used in lamination. The air-dry and oven dry densities, cell wall density and porosity, the value of volume density, shrinkage in a tangential and radial direction and volume swelling amounts were determined by preparing the specimens in accordance with the standards.
