    During the winter and spring of 1991 we made preparations for sampling on three legs of the US World Ocean Circulation Experiment in the Pacific Ocean. These transects, postponed from an original start date early in 1991, took place between May 31 to October 1. For the project, 1400 0.5 liter Pyrex sampling bottles were used for the collection of sea water. A second major pre-expedition task was the construction of a dual titration cell system of new design, as described in the original proposal and our previous semi-annual report.

    Project`s objective is to evaluate state-of-the-art methods for locating pipelines in shallow (less than 15 ft) water and for determining and monitoring their burial depths. The following recommendations are made on the research needed in three areas for locating near-shore, shallowly buried pipelines: (1) Sensors: The pipeline industry has selected the magnetic gradiometer array (GA) as a preferred sensor method. Other potential methods exist as backups. No additional research is recommended. (2) Remotely Operated Vehicles (ROVs): The Pipeline Research Committee is pursuing development of a prototype ROV is deliver the GA or other similar equipment to pipeline locations. (3) Phenomena: The data being collected from research on the phenomena affecting seabed conditions and the bathymetric data being collected along the Gulf Coast should be synthesized. This new effort should focus on identifying erosion-prone areas with respect to present and potential future pipeline locations. Technical approach is to get the broadest perspective on the concerns related to the determination of burial conditions for offshore pipelines, Argonne National Laboratory (ANL) contacted individuals and organizations from the gas and petroleum industries, hardware and software vendors, academicians, and representatives from the government. A literature survey yielded the names of persons within academia who are presently working on similar applications with sensors. In the oil and gas industry, individuals and organizations involved in the Pipeline Research Committee made extensive contributions to the review and also provided the names of meaningful contacts from among their vendors. Discussions were held with the various persons both on the telephone and face to face. Vendors provided background materials and overview presentations on their capabilities for ANL to review.

    Two FTIR spectrometers were employed in the late winters 1990 and 1991 in Esrange, North Sweden, and in Ny Aalesund, Spitsbergen to detect zenith column amounts of several trace gases. Time series of column amounts of the trace gases O3, N2O, CH4, HNO3, NO2, CHl, and HF have been derived from the measured spectra. Additionally, some information on the vertical distribution of HCl could be obtained by analyzing the spectral line shapes. The results are interpreted in terms of dynamical and chemical processes.

    The octane requirement increase (ORI) of 80 1990 and 43 1991 model-year vehicles operated on commercial fuels in customer-like service has been determined. These ORI values were established from the octane number requirements regardless of whether they were determined at maximum- or part-throttle. At 15,000 miles, the mean ORI of the 1990 vehicles with full-boiling range fuels (FBRU) was 4.4 (R+M)/2 octane numbers, 5.2 Research octane numbers (RON), and 3.5 Motor octane numbers (MON). The ORI of individual vehicles ranged from no increase to 1 1. 1 (R + M)/2 numbers. At 15,000 miles, the mean ORI of the 1991 vehicles with full-boiling range fuels (FBRU) was 3.3 (R+M)/2 numbers, 4.1 RON, and 2.6 MON. Individual vehicle ORI ranged from no increase to 9.2 (R + M)/2 numbers. As opposed to a number of 1989 models submitted which showed a somewhat unusual variation with mileage, the 1990 and 1991 models behaved in the more traditional manner.

  12. MLT dependence in the relationship between plasmapause, solar wind, and geomagnetic activity based on CRRES: 1990-1991

    Using the database of CRRES in situ observations of the plasmapause crossings, we develop linear and more complex plasmapause models parametrized by (a) solar wind parameters V (solar wind velocity), BV (where B is the magnitude of the interplanetary magnetic field (IMF)), and dΦmp/dt (which combines different physical mechanisms which run magnetospheric activity), and (b) geomagnetic indices Dst, Ap, and AE. The complex models are built by including a first harmonic in magnetic local time (MLT). Our method based on the cross-correlation analyses provides not only the plasmapause shape for different levels of geomagnetic activity but additionally yields the information of the delays in the MLT response of the plasmapause. All models based on both solar wind parameters and geomagnetic indices indicate the maximal plasmapause extension in the postdusk side at high geomagnetic activity. The decrease in the convection electric field places the bulge toward midnight. These results are compared and discussed in regard to past works. Our study shows that the time delays in the plasmapause response are a function of MLT and suggests that the plasmapause is formed by the mechanism of interchange instability motion. We observed that any change quickly propagates across dawn to noon, and then at lower rate toward midnight. The results further indicate that the instability may propagate much faster during solar maximum than around solar minimum. This study contributes to the determination of the MLT dependence of the plasmapause and to constrain physical mechanism by which the plasmapause is formed.

    The study area is located in southern Elmore County, southwestern Idaho, and includes the Mountain Home Air Force Base located approximately 10 mi southwest of the city of Mountain Home. Chemical analyzes have been made periodically since the late 1940's on water samples from supply wells on the Air Force Base. These analyses indicate increases in specific conductance and in concentrations of nitrogen compounds, chloride, and sulfate. The purposes of this report, which was prepared in cooperation with the Department of the Air Force, are to describe the seasonal changes in water quality and water levels and to depict the directions of ground-water movement in the regional aquifer system and perched-water zones. Although data presented in this report are from both the regional ground-water system and perched-water zones, the focus is on the regional system. A previous study by the U.S. Geological Survey (Parliman and Young, 1990) describes the areal changes in water quality and water levels during the fall of 1989. During March, July, and October 1990, 141 wells were inventoried and depth to water was measured. Continuous water-level recorders were installed on 5 of the wells and monthly measurements of depth to water were made in 17 of the wells during March 1990 through February 1991. Water samples from 33 wells and 1 spring were collected during the spring and fall of 1990 for chemical analyses. Samples also were collected monthly from 11 of those wells during April to September 1990 (table 1). Selected well-construction and water-use data and measurements of depth to water for 141 wells are given in table 2 (separated sheets in envelope). Directions of ground-water movement and selected hydrographs showing seasonal fluctuations of water levels in the regional ground-water system and perched-water zones are shown on sheet 2. Changes in water levels in the regional ground-water system during March to October 1990 are shown on sheet 2.

    The Office of Health and Environmental Research, of the US Department of Energy (DOE), actively supports global survey investigations of carbon dioxide in the oceans. This large scale study is in conjunction with the hydrographic program of the World Ocean Circulation Experiment (WOCE/HP). On ocean cruises operated by WOCE/HP, carbon dioxide analysis groups, from various oceanographic institutions, perform shipboard chemical measurements of the inorganic carbon system in the ocean. Measurements of total dissolved inorganic carbon (DIC) are of central importance to this carbon survey. Shipboard measurements of DIC were made by employing a coulometric technique. The majority of coulometric measurements were made on an integrated automatic device, the Single Operator Multi-Parameter Metabolic Analyzer (SOMMA). In addition to DIC determinations, shipboard analytical groups measured at least one additional parameter of sea water carbon chemistry. This was done to more fully characterize the inorganic carbon system of the sea water sample. This thechnical data report presents DIC and ALK measurements performed in the SIO laboratory on replicate samples collected on the five expedition legs of the WOCE/HP cruises.

    We report photometry and radial velocities of the R Coronae Borealis (RCB) star R CrB, obtained during 1991. We compare these observations with published photometry obtained during 1990 and velocities obtained during 1990 and 1991, and analyse these data using Fourier techniques. In line with the conclusions of earlier analyses, the pulsational nature of R CrB is difficult to quantify, particularly on timescales of longer than a yea The 1990 data are possibly consistent with the presence of a 43-d radial pulsation mode. During 1991 there was some evidence for a periodicity near this value in the radial velocities, but not in the photometric data. Additional data are desirable to investigate the possible presence of one or more periodicities in the light and radial velocity curves.

    The Maryland Department of Natural Resources Marine Mammal and Sea Turtle Stranding Program was established in the fall of 1990, and responded to their first documented sea turtle stranding in the summer of 1991. Over this twenty-five year period, 575 dead strandings of sea turtles have been documented. This research project analyzes all sea turtle case files from the initiation of this program for the following parameters in order to associate stranding trends; species, location (Atlantic Ocean v. Chesapeake Bay), seasonality, length, relative age, condition code, and sex. Further understanding these protected species will assist in conserving their coastal ecosystem and securing these species a sustainable future. Along with the parameters previously discussed, this study will also consider the factors contributing to the animal's death, if determined. These potential causes incorporate natural causes such as disease, and also detail instances of human interaction, including: dredge takes, commercial or recreational fishing interaction, power plant entrainment, propeller and boat strikes. A total of approximately 17% of the dead stranded sea turtles Maryland Department of Natural Resources responded to were found to have some proven aspect of human interaction. Lastly, in order to further investigate for human interaction stomach contents were analyzed for plastics or other forms of marine debris. This project will contribute to MD DNR and NOAA's mission, goals, and objectives by further understanding these protected species in order to conserve their coastal ecosystem and secure these species a sustainable future.

    An improved method to estimate the amounts of carbon released during fires in the boreal forest zone of Alaska in 1990 and 1991 is described. This method divides the state into 64 distinct physiographic regions and estimates areal extent of five different land covers: two forest types, peat land, tundra, and nonvegetated. The areal extent of each cover type was estimated from a review of topographic maps of each region and observations on the distribution of foreat types within the state. Using previous observations and theoretical models for the two forest types found in interior Alaska, models of biomass accumulation as a function of stand age were developed. Stand age distributions for each region were determined using a statistical distribution based on fire frequency, which was from available long-term historical records. Estimates of the degree of biomass combusted were based on recent field observations as well as research reported in the literature. The location and areal extent of fires in this region for 1990 and 1991 were based on both field observations and analysis of satellite (advanced very high resolution radiometer (AVHRR)) data sets. Estimates of average carbon release for the two study years ranged between 2.54 and 3.00 kg/sq m, which are 2.2 to 2.6 times greater than estimates used in other studies of carbon release through biomass burning in boreal forests. Total average annual carbon release for the two years ranged between 0.012 and 0.018 Pg C/yr, with the lower value resulting from the AVHRR estimates of fire location and area.

The research aimed to gain a deeper understanding of the social factors surrounding the transmission of sexually transmitted infections, which had escalated following a local gold rush in 1989. Although HIV/AIDS was a very minor health issue in Papua New Guinea at that time, medical staff were aware of the likelihood of the disease becoming prevalent in the highlands in the near future. The research indicated that many people regarded sexually transmitted infections (STIs) as a nuisance, rather than a serious health risk. Discussions with chronic sufferers revealed that they were more concerned about the dangers of infertility than the immediate effects of the infections. The paper considers the risk-taking that the people of Tari, the Huli, were prepared to accept and suggests ways in which these risks might be minimized.

    Headspace oxygen contents of several designated drums containing {minus}l inch and {minus}{1/4} inch coal were measured. These measurements were later discontinued by agreement with the Project Manager, as the leakage of plastic drums and buckets has been well documented. During the current reporting period a total of 65 data printouts were distributed. In addition, 10 special data requests were fulfilled by either search/sort and printout or creation of a data disk, resulting in distribution of limited information on 4,479 samples. Several preliminary requests for Sample Bank and Data Base information and price quotations have also been handled. Four hundred copies of the 61-page second edition of the booklet ``The Penn State Coal Sample Bank and Data Base`` were received from the printer. Changes in format have allowed increased content in fewer pages, to reduce printing and mailing costs. Three hundred thirty-nine copies were distributed. Data generated on samples DECS-1 through DECS-14 were added to the Penn State Coal Data Base. Map reference data were verified for all 14 samples.

    The Idaho augmented fish health monitoring contract DE-A179-87BP65903 was awarded in June 1987 and fully implemented in January 1988. The fourth annual report of activities serviced under this contract is presented. The prevailing fish health problems in 1990 include persistent infections caused by Mvxobolus cerebralis and Flexibacter osvchronhilus. Subclinical infections of Renibacterium salmoninarum have been confirmed in pools of chinook kidney tissues using Enzyme-linked immunosorbant assay (ELISA), but to date, mortality and clinical signs were not apparent in juvenile anadromous fish. Clinical signs were observed in returning brood chinook at all chinook facilities. Furunculosis (Aeromonas salmonicida) was isolated in conjunction with mortality at Niagara Springs in the spring of 1991. The anadromous fish pathologist position was accepted by Doug Munson in July 1991. Complete diagnostic and inspection services were provided to eleven Idaho anadromous facilities. This report describes work done to meet contract agreements and summarizes the fish health findings of anadromous stocks reared at and returning to Idaho's facilities during 1990-1991.

    1994-09-01

    This research models the geographic variation in lead poisoning among children living in Massachusetts between 1990 and 1991. Elevated levels of blood lead, which reduce educational performance, arise because children are exposed to unnaturally concentrated sources of lead in the built environment. A Poisson regression model indicates that a large number of children with lead poisoning may be detected in towns with a high proportion of older housing, female headed households, African-Americans, and an industrial heritage. Our results suggest links between the processes of urbanization and industrialization in Massachusetts and today's lead poisoned landscapes.

    Ordón˜ez V, Milton I.; Rey G, Carlos A.

    1997-05-01

    During 1989-1992, two electronic tilt meters named Cráter and Peladitos, and a short level line named Las Piedras, were used for monitoring Galeras volcano. The two tilt meters detected considerable changes of uplift mainly from June to November 1991. The Cráter station showed cumulative values of more than 600 microradians, while the Peladitos station exhibited values of more than 100 microradians. The short level line showed inflationary tilt of more than 20 microradians in 1989. This behavior was related to increases in the daily occurrence of long-period seismic events during July-November 1991 caused by the rise and extrusion of a lava dome, which was subsequently destroyed in July 1992. At the end of 1990, the deformation source was located at a depth of 2-3 km. By December 1991, the source had migrated to less than 500 m in depth. The magma ascent rate was 1-4 m/day during this period. The dome emplaced in the crater had a volume between 300,000 to 400,000 m 3. Using a hydrodynamic model and the tilt changes registered by the Peladitos station, the volume of the magma body is estimated at approximately 2.8 × 10 6 m 3.

    Setline and angling techniques were used to sample 56 white sturgeon Acioenser transmontanus from the Kootenai River in 1991. Of those sampled, nine were recaptures from previous years of this study. A total of 382 white sturgeon were captured from March 1989 through October 1991. Fork lengths of white sturgeon in the sample ranged from 88-274 cm. Our data indicated there was a complete lack of recruitment of juveniles into the population. The youngest fish sampled was of the 1977 year class. The population was estimated at 880 individuals with a 95% confidence interval of 638 to 1,211. Annual mortality of white sturgeon since 1982 is 3.74%. Approximately 80% of the population was more than 20 years old and was reproductively mature. Surgical examination of 309 white sturgeon since 1989 indicated that approximately 7% of the female white sturgeon and 30% of the male white sturgeon are reproductive each year. The ratio of males to females was estimated at 1:l. White sturgeon sampled and released with and without surgical examination were recaptured at equal rates. An ongoing sonic telemetry study has documented long distance movements by adults. White sturgeon regularly move across the British Columbia - Idaho border. White sturgeon seek out deep holes in the river or migrate to Kootenay Lake during late fall, During spring and early summer of both 1990 and 1991 reproductively mature white sturgeon moved from 15 to 110 km upriver and congregated within 10 km downriver from Bonners Ferry in areas of elevated water velocity. This behavior coincided with increasing discharge and water temperatures. Developing white sturgeon eggs were recovered from the river near Bonners Ferry on July 3, 1991. Contamination of eggs by organochloride compounds were less in recent samples from the Kootenai River than in a single sample collected in 1982. White sturgeon eggs from the Kootenai River fish contained approximately one tenth the organochloride compounds of white sturgeon eggs

  7. Performance and reliability of solar progress photovoltaic plant, 1990--1991

    1993-04-01

    This biennial report provides the comprehensive description and results of the performance monitoring and diagnostic activities conducted on the Solar Progress Photovoltaic System during the two-year period January 1990 to December 1991. Solar Progress is a nominal 15 kWp grid-connected photovoltaic system. The system was installed in August 1988 at one of Florida Power Corporation's substations near Orlando, Florida. The primary objective of this work was to evaluate the performance and reliability of this amorphous silicon photovoltaic system. Hourly performance data and periodic diagnostic tests on the system were used to investigate the specific performance and reliability issues. The Solar Progress System is owned and operated by the Florida Power Corporation (FPC). The system's performance has been monitored and periodic diagnostic tests to evaluate subsystem reliability have been conducted by the Florida Solar Energy Center (FSEC). During the two-year reporting period, the power output of the array degraded by 10 percent and the array operating efficiency has reduced from 4.0 percent in January 1990 to 3.6 percent in December 1991. In addition to the systematic light-induced degradation (Staebler-Wronski effect), the array efficiency varies during a year due to other effects, including the seasonal annealing effect and spectral effect. During the summertime, with higher array operating temperatures, the array efficiency increases due to the annealing effect and also due to more favorable spectral distribution of solar irradiance for amorphous silicon modules. With the return of winter, the cycle repeats itself and the array efficiency drops again due to the process reverse of annealing, and also due to less favorable spectral distribution. The cumulative effect of annealing and changes in the spectral distribution results in array efficiency values that are relatively about 10 percent lower in the winter than in the summertime.

    The purpose of this study was to evaluate the impact of new treatments by examining the changes between 1990 to 1991 and 2000 to 2001 in in-hospital mortality rates and hospital charges in adult patients with stroke. From the Nationwide Inpatient Survey, the largest all-payer inpatient care database in the United States, patients with stroke admitted in 1990 to 1991 or 2000 to 2001 were studied. We analyzed hospital charges (adjusted for inflation based on the Consumer Price Index of the Bureau of Labor Statistics) and patient outcomes by type of institution: rural, urban nonteaching, and urban teaching in 1990 to 1991 and in 2000 to 2001. In 1990 to 1991, there were 1 736 352 admissions for cerebrovascular diseases, and in 2000 to 2001, there were 1 958 018 admissions. The number of admissions in urban teaching hospitals increased by 13%, 19%, and 25%, for ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage, respectively. The overall in-hospital mortality rate relatively declined by 36% for ischemic stroke, by 6% for intracerebral hemorrhages, and by 10% for subarachnoid hemorrhage. The mean hospital charges increased from $10 500 to $16 200 for patients with ischemic stroke, from $18 300 to $28 800 for patients with intracerebral hemorrhage, and from $37 400 to $65 900 for patients with subarachnoid hemorrhage. Mortality rates among patients admitted after ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage were all lower in urban teaching hospitals than in rural and urban nonteaching hospitals and the mean charges per admission were all higher. There has been an increase in the inflation-adjusted hospital charges for all patients with stroke and a reduction in mortality rates for all stroke subtypes probably related to an increase in the proportion of patients with stroke admitted to urban teaching hospitals.

    A questionnaire survey of head lice treatment was conducted in four schools--each including a nursery and an elementary school--in the Bordeaux area. Two schools were situated in the centre of the city, one in a suburban area and one in a rural area (50 km from the city). Four-page questionnaires were filled in anonymously by the parents in April 1991; 840 answers were obtained (80 p. 100 response rate). Between January 1990 and March 1991, 48.7 p. 100 of children had at least one episode of head lice infestation (infestation rates varied from 38.8 to 62.6 p. 100 depending on the schools); 30.5 p. 100 of children were contaminated for the first time during that period. Lice were detected by the parents in 95 p. 100 of the cases. The prevalence of lice was higher in females (60 p. 100) than in males (40 p. 100). The highest prevalence was noted in the suburban school where 17 p. 100 of the parents were unemployed at the time of the survey. The peak age for head lice was 7, but 19.4 p. 100 of nursery school children aged 2-4 years had been contaminated at least once. Impetigo was rare (1.2 p. 100), and pruritus was noted in only 14.2 p. 100 of the cases. Most children had been contaminated at school. Curative treatment was counselled by a chemist in 87 p. 100 of the cases. Pyrethrins were used in 81 p. 100, and the shampoo (Hegor) plus spray (Paraspecial Poux) association was the most frequent, totalling two-thirds of prescriptions.(ABSTRACT TRUNCATED AT 250 WORDS)

    This report describes the work performed at Membrane Technology and Research, Inc. (MTR). The period covered is from September 29, 1990 to April 29, 1991, representing Phase 1 of the project. The overall objective of the project is the design, construct and demonstrate in the field a 50 scfm condensation/membrane separation system able to recover volatile organic compounds from effluent air streams. In the first phase of the program, a number of the high-pressure membranes modules to be installed in the system were constructed and evaluated. The results were satisfactory and no further module development work is required. The Field Demonstration Unit has also been designed. All of the major components have been selected and costed. The system can be constructed within the proposed budget. As a result of a visit to the host demonstration site (Great Lakes Chemical (GLC), El Dorado, Arkansas Plant), the Phase 2 program has been modified to include construction of small, high-pressure Field Module Evaluation Unit to be installed at GLC during the Phase 2 program. The host site engineers are prepared to install and monitor this unit. This additional work can be accomplished within the current budget and will provide valuable data prior to installation of the large Field Demonstration Unit. 18 figs., 8 tabs.

    The authors report on data which measures the solar ultraviolet irradiance between 300 and 310nm at Ushuaia, Argentina over the period Sept 1990 to Mar 1991. Ushuaia is 10[degrees] or more north of the Antarctic ozone hole, though it may or may not be in the fringe of the polar vortex. Over the Antarctic there has been an observed enhancement in solar ultraviolet irradiance on the surface of the Earth, though it has little relevance due to the sparse population density. In the northern hemisphere there has been observed an overall decrease in column ozone, but no recorded change in spectral irradiance, though there are several possible explanations for this observation. In the southern hemisphere the question of whether polar air masses could migrate north following the collapse of the polar vortex, and produce regions of depleted ozone, with consequent ultraviolet irradiance increase is looked at in this paper. Substantial increases in ultraviolet irradiance are observed from this observation period, but because of the limited data set it is difficult to say for sure that such an air mass migration was the origin. However, the net effect is still a substantial increase in solar ultraviolet irradiance, with possible biological consequences.

    Following the 1990-1991 Gulf War, Gulf War veterans (veterans) reported health symptoms more commonly than non-deployed groups. This article examines symptom persistence, incidence and prevalence 20 years on. In 2000-2003 and 2011-2012, a 63-item symptom checklist was administered to 697 veterans and 659 comparison group. Symptomatology was compared using log-binomial regression. Both veterans and comparison group reported significantly increased prevalence (3-52%) over time in more than half the symptoms, with a similar overall rate of increase. Half the symptoms had higher incidence (risk-ratios ranged 1.43-1.50) and a quarter were more persistent (risk-ratios ranged 1.12-1.20) in veterans than the comparison group. Symptomatology increased in both groups over time, but persisted to a similar extent and had higher incidence among veterans than the comparison group. The gap in symptom prevalence between the two groups remained unchanged. These findings suggest enduring health consequences of Gulf War service. © 2015 Commonwealth of Australia.

    Six hundred eighty-two (682) containers of soil were generated at Mound Plant between April 1 and October 31, 1990 as a result of the excavation of soils containing plutonium-238 at two ongoing Decontamination and Decommissioning (D&D) Program sites; these areas are known as Area 14, the waste transfer system (WTS) hillside, and Area 17, the Special Metallurgical (SM) Building Area. The soils from these areas are part of the Mound Plant waste stream number AMDM-000000010, Contaminated Soil, and are proposed for shipment to the Nevada Test Site (NTS) for disposal as low-level radioactive waste. These containers of soil are currently in storage at Mound Plant. The purpose of this sampling and analysis was to demonstrate that the D&D soils comply with the waste acceptance requirements of the NTS, as presented In Nevada Test Site Defense Waste Acceptance Criteria, Certification, and Transfer Requirements (DOE 1988). The sealed waste packages, constructed of wood or metal, are currently being stored In Building 31 and at other locations throughout the Mound Plant.

    The Einstein Extended Medium Sensitivity Survey (EMSS) consists of 835 serendipitous X-ray sources detected at or above 4 times the rms level in 1435 IPC fields with their centers located away from the galactic plane. Their limiting sensitivities range from ~5*10-14 to to ~ 3*10-12 erg.cm-2.s-1 in the 0.3-3.5keV band. A total area of 778 square degrees of the high galactic latitude sky (|b|>20) has been covered. The analysis has been performed using data from the Rev 1 processing system at the CfA. The resulting EMSS catalog is a flux-limited and homogeneous sample of astronomical objects that can be used for statistical studies. Here we present the table listing all the sources taken from the publication referenced below and the optical identifications. At present over 96% of the 835 X-ray sources have been successfully identified in the following proportions: active galactic nuclei (QSO's, quasars and Seyfert), 51.1%; BL Lacertae objects, 4.3%; clusters of galaxies, 12.2%; normal galaxies, 2.1%; cooling flow galaxies, 0.6%; Galactic stars 25.8%; and unidentified, 3.9%. Most of the individual optical counterparts are previously unknown objects and so constitute large statistical samples independent of previously selection methods. The contents of the table is described below. The sky coverage computed for a specific assumed source spectrum is also given under "Additional Information" below.

    This report summarizes the activities of the research project entitled {open_quotes}Study of Chip Breaking Mechanisms in Orthogonal Cutting{close_quotes}. The research effort took place from April 1990 to June 1991. The overall objective of the project was to develop a systematic procedure for gaining a more fundamental understanding of chip breaking mechanics. Central to this objective is a computer model that can simulate chip formation in orthogonal cutting. This model has been under development for the past seven years at NCSU. The model is based on an Eulerian formulation of the finite element technique. The model simulates the cutting process for various tool geometries over a wide range of cutting conditions. The model can be used to predict chip geometry, cutting forces, plastic strains, strain rates, and temperatures in the workpiece and chip, as well as temperatures in the tool itself. Of particular significance is that specific tool geometries can be simulated. Therefore, the model can be used to systematically evaluate the strains, strain rates, temperature, and geometry of the chip as a function of a specific chip-breaker tool design. These results can provide the crucial information necessary to formulate a fundamental understanding of the chip breaking mechanism over a wide range of operating conditions and workpiece materials.

    Distribution, habitat use and survival of transplanted Columbian sharp-tailed grouse in the Tobacco Plains, Montana were studied from April, 1990 to August, 1991. For transplant purposes, 12 grouse (5 female and 7 male) were trapped on dancing grounds near Douglas Lake, British Columbia, Canada during spring, 1990. In April, 1991, trapping of 4 female and 2 male grouse for transplant occurred on the Sand Creek Wildlife Management Area in southeast Idaho while 3 additional males were transplanted from Douglas Lake. Minimum annual survival of transplanted grouse in the Tobacco Plains is relatively high (47%). High survival is possibly due to 2 factors: (1) topography and habitat characteristics that discourage dispersal and (2) the presence of limited but relatively good habitat. Two of 18 radio-equipped grouse dispersed out of the study area, while 2 others survived in the area for over 590 days. A negative correlation in distances moved between consecutive relocations and length of survival was seen in radio-equipped grouse in this study. Data collected during this study showed the importance of habitat associated with the Dancing Prairie Preserve. Three of 5 females transplanted in 1990 attempted to nest after being released. Nesting and brood rearing sites were characterized by dense grass cover with an average effective height {ge}20 cm. Shrub cover was associated only with brood rearing sites. Overall habitat use by transplanted Columbian Sharp-tailed grouse showed an apparent avoidance of agricultural land and use of other habitat types in proportion to their availability.

    Among all deaths to Connecticut residents (1990/91), 1260 were acceptable Spanish-surname matches (using father's surname for females), of which only 793 (62.9%) were identified as Hispanic origin on the death certificate. Certificates also identified 127 non-Spanish-surnamed Hispanics. With death rates for non-Hispanics used as the standard, the standardized mortality ratio for Hispanics based on the 920 (793 plus 127) deaths identified by the Hispanic-origin item was lower (by 33% in males and 36% in females) than that based on all 1387 (1260 plus 127) Hispanics. Spanish-surname matching should improve estimation of mortality rates in some Hispanic populations. PMID:7604930

  10. Predicting the Performance of Chain Saw Machines Based on Shore Scleroscope Hardness

    Tumac, Deniz

    2014-03-01

    Shore hardness has been used to estimate several physical and mechanical properties of rocks over the last few decades. However, the number of researches correlating Shore hardness with rock cutting performance is quite limited. Also, rather limited researches have been carried out on predicting the performance of chain saw machines. This study differs from the previous investigations in the way that Shore hardness values (SH1, SH2, and deformation coefficient) are used to determine the field performance of chain saw machines. The measured Shore hardness values are correlated with the physical and mechanical properties of natural stone samples, cutting parameters (normal force, cutting force, and specific energy) obtained from linear cutting tests in unrelieved cutting mode, and areal net cutting rate of chain saw machines. Two empirical models developed previously are improved for the prediction of the areal net cutting rate of chain saw machines. The first model is based on a revised chain saw penetration index, which uses SH1, machine weight, and useful arm cutting depth as predictors. The second model is based on the power consumed for only cutting the stone, arm thickness, and specific energy as a function of the deformation coefficient. While cutting force has a strong relationship with Shore hardness values, the normal force has a weak or moderate correlation. Uniaxial compressive strength, Cerchar abrasivity index, and density can also be predicted by Shore hardness values.

    The ARIES research program is a multi-institutional effort to develop several visions of tokamak reactors with enhanced economic, safety, and environmental features. The aims are to determine the potential economics, safety, and environmental features of a range of possible tokamak reactors, and to identify physics and technology areas with the highest leverage for achieving the best tokamak reactor. Four ARIES visions are currently planned for the ARIES program. The ARIES-1 design is a DT-burning reactor based on ``modest`` extrapolations from the present tokamak physics database and relies on either existing technology or technology for which trends are already in place, often in programs outside fusion. ARIES-2 and ARIES-4 are DT-burning reactors which will employ potential advances in physics. The ARIES-2 and ARIES-4 designs employ the same plasma core but have two distinct fusion power core designs; ARIES-2 utilize the lithium as the coolant and breeder and vanadium alloys as the structural material while ARIES-4 utilizes helium is the coolant, solid tritium breeders, and SiC composite as the structural material. Lastly, the ARIES-3 is a conceptual D-{sup 3}He reactor. During the period Dec. 1, 1990 to Nov. 31, 1991, most of the ARIES activity has been directed toward completing the technical work for the ARIES-3 design and documenting the results and findings. We have also completed the documentation for the ARIES-1 design and presented the results in various meetings and conferences. During the last quarter, we have initiated the scoping phase for ARIES-2 and ARIES-4 designs.

    A one-year study (6/90-7/91) was conducted to estimate the deposition of atmospheric contaminants to the Maryland portion of the Chesapeake Bay. The studied contaminants included the trace elements polychlorinated biphenyl (PCBs) congeners, and polycyclic aromatic hydrocarbons (PAHs). Weekly integrated samples of aerosol and precipitation were collected for elemental constituents at two sites, one on the northeastern (Wye) and one on the mid-bay western (Elms) Maryland shore. Organic contaminants in precipitation samples were collected bi-weekly at the Elms site only. Major elements in wet deposition, as related to acid rain monitoring, are being measured at these sites by other groups.

The studied contaminants included the trace elements polychlorinated biphenyl (PCBs) congeners, and polycyclic aromatic hydrocarbons (PAHs). Weekly integrated samples of aerosol and precipitation were collected for elemental constituents at two sites, one on the northeastern (Wye) and one on the mid-bay western (Elms) Maryland shore. Organic contaminants in precipitation samples were collected bi-weekly at the Elms site only. Major elements in wet deposition, as related to acid rain monitoring, are being measured at these sites by other groups.

    The Department of Petroleum Engineering at The University of Texas at Austin is one of more than 20 such departments in the United States and more than 40 worldwide. The department has more than 20 faculty members and, as of the fall of 1990, 146 undergraduate and 156 graduate students. During the 1990--91 academic year, undergraduate enrollment is up slightly from the several downturns that began in 1986; graduate enrollment continues to increase, significantly in the number of Ph.D. candidates enrolled. The 1990--91 academic year was one of consolidation of gains. A remote teaching program in the Midland-Odessa area was initiated. During 1991, the Center for Petroleum and Geosystems Engineering (CPGE) continued its large, diversified research activities related to oil, gas and geopressured/geothermal energy production, energy and mineral resources analysis, and added new research projects in other areas such as groundwater remediation. Many of these research projects included interdisciplinary efforts involving faculty, research scientists and graduate students in chemistry, mathematics, geology, geophysics, engineering mechanics, chemical engineering, microbiology and other disciplines. Several projects were undertaken in cooperation with either the Bureau of Economic Geology or the Institute for Geophysics at The University of Texas at Austin. Collaborative research projects with scientists at Brookhaven National Laboratory, Los Alamos National Laboratory, Rice University, and Sandia National Laboratory were also initiated. About 43 companies from seven countries around the world continued to provide the largest portion of research funding to CPGE.

    Concerns about reproductive health persist among U.S. military members who served in the 1990-1991 Gulf War. This study explores the long-term impact of 1990-1991 Gulf War deployment on the prevalence of birth defects among infants of Gulf War veterans. Health care data from the Department of Defense Birth and Infant Health Registry and demographic and deployment information from the Defense Manpower Data Center were used to identify infants born between 1998 and 2004 to both male and female 1990-1991 Gulf War veterans. Multivariable logistic regression models estimated the adjusted odds of any birth defect and eight specific birth defects among infants of deployers versus non-deployers. In addition, birth defects were evaluated among infants born to 1990-1991 Gulf War veterans with deployment-specific exposures. Among 178,766 infants identified for these analyses, 3.4% were diagnosed with a birth defect in the first year of life. Compared to infants of non-deployers, infants of deployers were not at increased odds of being diagnosed with a birth defect, or any of eight specific birth defects, in the first year of life. A slightly increased prevalence of birth defects was observed among infants born to men who deployed to the 1990-1991 Gulf War for 153 to 200 days compared to those who deployed for 1 to 92 days. No other deployment-specific exposures were associated with birth defects in these infants. The 1990-1991 Gulf War deployers, including those with specific exposures of concern, were not found to be at increased risk for having infants with birth defects 7 to 14 years after deployment.

    This reporting period marks the end of Phase 1 Screening and the beginning of Phase 2 Assessment. During Phase 1, radon detectors were shipped to all Department of Navy (DON) sites with family housing areas, child-care centers, schools, hospitals, bachelor quarters, and brigs. 14,350 radon detectors have been returned and analyzed, and 3.4% of the housing and nonhousing results obtained were above the Environmental Protection Agency`s action level of 4 pCi/L. Suspect screening results were confirmed. Phase 2 Assessment consists of two categories, Assessment and Phase 2 Screening. All activities with radon in excess of 4 pCi/L are included in Assessment. Phase 2 Screening consists of screening Navy-Owned Reserve Centers, Rescreening (sites with inconclusive data), and screening of Nonhousing Unit Identity Codes [(UICs) activities without Phase 1 test structures]. All housing assessment was scheduled to be conducted during 1991 and 1992. Phase 2 housing and nonhousing have been established. In addition, a quality assurance program and technical guidebook have been developed to achieve accurate data during Phase 2. As of July 1, 1991, assessment of housing was 40% complete, nonhousing 4%, reserve centers 100%, and nonhousing UICs were 9% complete.

    KPMG Peat Marwick (KPMG), Certified Public Accountants, has completed its audit of the Department of Energy`s Uranium Enrichment Activity (UEA) financial.statements as of September 30, 1991. The purpose of the audit was to determine whether (1) the financial statements were presented fairly in accordance with applicable accounting principles, (2) the auditee complied with all applicable laws and regulations that may have materially affected the financial statements, and (3) the internal accounting controls, taken as a whole, were adequate. The US Government, through the Department of Energy (DOE) and the management and operating contractor, operates the UEA to enrich uranium hexafluoride in the isotope U-235 for commercial power reactor operators, as further discussed in note 1 of the financial statements. The enrichment of uranium for Government program users, which had been a function of UEA, was transferred outside the UEA affective September 30, 1991, as described in note 3 of the financial statements. UEA is a part of DOE and does not exist as a separate legal entity. For financial reporting purposes, the entity is defined as those activities which provide enriching services to its customers. The financial statements are prepared by extracting and adjusting UEA related data from the financial records of DOE and its contractors.

    In anticipation of the fall 1988 start up of effluent discharges into Upper Three Runs Creek by the F/H Area Effluent Treatment Facility of the Savannah River Site, Aiken, SC, a two and one half year biological study was initiated in June 1987. Upper Three Runs Creek is an intensively studied fourth order stream known for its high species richness. Designed to assess the potential impact of F/H area effluent on the creek, the study included qualitative and quantitative macroinvertebrate stream surveys at five sites (see map), chronic toxicity testing of the effluent, water chemistry and bioaccumulation analysis. In a March 1990 study of the potential impact of F/H Area effluent on the macroinvertebrate communities of Upper Three Runs Creek was extended, with reductions in the number of sites to be sampled and in the frequency of water chemistry sampling. This report presents the results of macroinvertebrate stream surveys at three sites, chronic toxicity testing of the effluent and water chemistry analysis of the three stream sites and the effluent from March 1990 to July 1991.

Site positions are tabulated on a yearly basis from 1979 through 1992. Site velocities are presented in both geocentric Cartesian coordinates and topocentric coordinates. Baseline evolution is plotted for 175 baselines. Rates are computed for earth rotation and nutation parameters. Included are 104 sources, 88 fixed stations and mobile sites, and 688 baselines.

  20. New land-based method for surveying sandy shores and extracting DEMs: the INSHORE system.

    The INSHORE system (INtegrated System for High Operational REsolution in shore monitoring) is a land-base survey system designed and developed for the specific task of monitoring the evolution in time of sandy shores. This system was developed with two main objectives: (1) to produce highly accurate 3D coordinates of surface points (in the order of 0.02 to 0.03 m); and (2) to be extremely efficient in surveying a beach stretch of several kilometres. Previous tests have demonstrated that INSHORE systems fulfil such objectives. Now, the usefulness of the INSHORE system as a survey tool for the production of Digital Elevation Models (DEMs) of sandy shores is demonstrated. For this purpose, the comparison of DEMs obtained with the INSHORE system and with other relevant survey techniques is presented. This comparison focuses on the final DEM accuracy and also on the survey efficiency and its impact on the costs associated with regular monitoring programmes. The field survey method of the INSHORE system, based on profile networks, has a productivity of about 30 to 40 ha/h, depending on the beach surface characteristics. The final DEM precision, after interpolation of the global positioning system profile network, is approximately 0.08 to 0.12 m (RMS), depending on the profile network's density. Thus, this is a useful method for 3D representation of sandy shore surfaces and can permit, after interpolation, reliable calculations of volume and other physical parameters.

    The secular variation of the main geomagnetic field during the periods 1980-1985 and 1985-1990 was analyzed in terms of spherical harmonics up to the eighth degree and order. Data from worldwide magnetic observatories and the Navy's Project MAGNET aerial surveys were used. The resulting pair of secular-variation models was used to update the Definitive Geomagnetic Reference Field (DGRF) model for 1980, resulting in new mainfield models for 1985.0 and 1990.0. These, along with the secular-variation model for 1985-1990, were proposed for the 1991 revision of the International Geomagnetic Reference Field (IGRF). -Author

    Total ozone and the vertical distribution of ozone were measured at Pretoria between 1965 and 1968. Total ozone measurements recommenced in Pretoria in August 1989, and measurements of the vertical distribution of ozone near Pretoria recommenced in July 1990. Relative to the earlier data, mean monthly total ozone values are significantly higher in all months, with a mean annual relative increase of 12 percent. The recent profiles show a significant increase in the mean monthly concentration of ozone in the lowest 12 km. Concurrent to this increase a relative decrease in ozone concentration is shown between 12 and 42 km. The increased ozone concentration in the lower troposphere may be related to urbanization and the increase in ozone-forming nitrogen oxides over the last two decades. It is suggested that the decreased ozone concentration in the stratosphere and upper troposphere is evidence of the global decrease in the mid-latitudes of the Southern Hemisphere.

    The Community Radiation Monitoring Program is a cooperative effort between the US Department of Energy (DOE), the US Environmental Protection Agency (EPA), the Desert Research Institute (DRI), a division of the University and Community College System of Nevada, and the Nuclear Engineering Laboratory of the University of Utah (U of U). This eleventh year of the program began in the summer of 1991 and the work continues as an integral part of the DOE-sponsored long-term offsite radiological monitoring effort that has been conducted by EPA and its predecessors since the inception of nuclear testing at the Nevada Test Site (NTS). The primary objectives of this program are still to increase the understanding by the people who live in the area surrounding the NTS of the activities for which the DOE is responsible, to enhance the performance of radiological sampling and monitoring, and to inform all concerned of the results of those efforts. One of the primary methods used to improve the communication link with the potentially impacted area has been the hiring and training of local citizens as Managers and program representatives in 19 communities adjacent to and downwind from the NTS. These Managers, active science teachers wherever possible, have succeeded, through their training, experience, community standing, and effort, in becoming a very visible, able and valuable asset in this link.

    Ozone sonde data of the winters 1988/89, 1989/90, and 1990/91 from a group of Arctic stations are used in this study. The ozone mixing ratio on several isentropic surfaces is correlated to the potential vorticity (P). The P is based on the initialized analysis data from the European Center for Medium-Range Weather Forecasts. Similar investigations were made by Lait et al. (Geophys. Res. Lett., 17, 521-524, March Supplement 1990) for the AASE campaign (January and February 1989), showing how the ozone mixing ratio varies with the distance to the edge of the vortex. Their findings are confirmed and extended to the following two winters. Furthermore we have studied the temporal development of the P-ozone correlations during these winters in order to recognize any chemical ozone depletion.

    In February, 1990, the Secretary of Energy, James Watkins approved a grant for a waste (management) education and research consortium program by New Mexico State University (NMSU) to the US Department of Energy (DOE) . This program known by the acronym, WERC'' includes NMSU, the University of New Mexico (UNM), the New Mexico Institute of Mining and Technology (NMIMT), the Los Alamos National Laboratory and the Sandia National Laboratories. The program is designed to provide an integrated approach to the national need via the following: (1) Education in waste management by the Consortium universities resulting in graduate, undergraduate, and associate degrees with concentration in environmental management. The term waste management is used in a broad sense throughout this paper and includes all aspects of environmental management and environmental restoration. (2) Research programs at the leading edge, providing training to faculty and students and feeding into the education programs. (3) Education and research at the campuses, as well as from three field sites. (4) Ties with other multi-disciplinary university facilities. (5) Ties with two National Laboratories located in New Mexico. (6) Technology transfer and education via an existing fiber optic network, a proposed satellite link, and an existing state-wide extension program. (7) An outreach program to interest others in environmental management, especially precollege students, minority students and practitioners in the field.

    As the US oceanographic research fleet shrinks, reducing seagoing opportunities for scientists and students, remote participation in cruises via telepresence will become increasingly vital. The Nautilus Exploration Program is improving the experience of shoreside participants through the development of new tools and methodologies for connecting them to expeditions in real time increasing accessibility to oceanographic cruises. The Scientist Ashore Program is a network of scientists around the world who participate in Exploration Vessel Nautilus expeditions from their own labs or homes. We have developed a suite of collaboration tools to allow scientists to view video and data in real time, as well as to communicate with ship-based and other shore-based participants to enable remote participation in cruises. Post-cruise, scientists and students may access digital data and biological and geological samples from our partner shore-based repositories: the University of Rhode Island Inner Space Center, Harvard Museum of Comparative Zoology, and URI Marine Geological Samples Lab. We present examples of successful shore-based participation by scientists and students in Nautilus expeditions. In 2013, Drs. Cheadle and John stood watch 24/7 with ten undergraduate and graduate students at the University of Wyoming, recording geologic features and samples, during a cruise to the Cayman Rise. The Straits of Florida & Great Bahama Bank cruise was co-led by Dr. Eberli at the University of Miami in 2014, greatly complementing existing data. That same year, the ISC hosted four early career scientists and their twelve undergraduate students who led dives from shore in collaboration with Dr. Carey, Lead Scientist at sea on the Kick'em Jenny Volcano & the Barbados Mud Volcanoes cruise. In 2015, 12 Scientists Ashore worked in collaboration with the ship-based team on the exploration of Galapagos National Park, and more than 20 are working with OET on post-cruise data & sample analysis.

    Measurements of currents and light transmission were made at bottom tripods and moorings arrayed across the northern California continental shelf along the Coastal Ocean Dynamics Experiment (CODE) "C" transect as part of the 1990-1991 Sediment Transport Events on Shelves and Slopes (STRESS) experiment. In combination with meteorological and wave data from the National Data Buoy Center Buoy 46013, these measurements provide information about the physical forcing and resultant resuspension and transport of bottom material between 21 November and 8 March. Sixteen events were identified in the wave, wind and current-meter records for this period. Only two were local storms with southerly winds, but they caused about half of the seasonal net transport. Seven were swell events that combined long-period waves generated by distant storms with local currents. At the 90-m site, swells interacted with the mean northward flow to produce northward transport. During six northerly wind events, upwelling-favorable winds often were sufficient to slow or reverse the mean northward flow and thus caused southward transport. A single current event, which produced moderate southward transport, was observed at the 130-m site. Net transport during the winter experiment was offshore at all sites, northward at the inner- and mid-shelf sites, but southward at the outer-shelf site. The results suggest that local storms with southerly winds may dominate seasonal transport, as on the Washington shelf, but significant transport also can occur during fair weather and during periods of northerly winds. ?? 1994.

    This report summarizes for the 15-month period of October 1990-- December 1991 the available dynamic hydrologic data collected, primarily on the White Oak Creek (WOC) watershed, along with information collected on the surface flow systems that affect the quality or quantity of surface water. The collection of hydrologic data is one component of numerous, ongoing Oak Ridge National Laboratory (ORNL) environmental studies and monitoring programs and is intended to: (1) characterize the quantity and quality of water in the flow systems; (2) assist with the planning and assessment of remedial action activities; and, (3) provide long-term availability of data and quality assurance. Characterization of the hydrology of the WOC watershed is critical for understanding the processes that drive contaminant transport in the watershed. Identification of spatial and temporal trends in hydrologic parameters and mechanisms that affect the movement of contaminants supports the development of interim corrective measures and remedial restoration alternatives. In addition, hydrologic monitoring supports long-term assessment of the effectiveness of remedial actions in limiting the transport of contaminants across Waste Area Grouping (WAG) boundaries and ultimately to the off-site environment. For these reasons, it is of paramount importance to the Environmental Restoration Program (ERP) to collect and report hydrologic data activities that contribute to the Site Investigations component of the ERP.

    The results of the investigative efforts for this jointly funded DOE-State of Texas research project achieved during the 1990-1991 year may be summarized as follows: Geological Characterization - Detailed maps of the development and hierarchical nature the fracture system exhibited by Austin Chalk outcrops were prepared. The results of these efforts were directly applied to the development of production decline type curves applicable to a dual-fracture-matrix flow system. Analysis of production records obtained from Austin Chalk operators illustrated the utility of these type curves to determine relative fracture/matrix contributions and extent. Well-log response in Austin Chalk wells has been shown to be a reliable indicator of organic maturity. Shear-wave splitting concepts were used to estimate fracture orientations from Vertical Seismic Profile, VSP data. Several programs were written to facilitate analysis of the data. The results of these efforts indicated fractures could be detected with VSP seismic methods.Development of the EOR Imbibition Process - Laboratory displacement as well as Magnetic Resonance Imaging, MRI and Computed Tomography, CT imaging studies have shown the carbonated water-imbibition displacement process significantly accelerates and increases recovery from oil saturated, low permeability rocks.Field Tests - Two operators amenable to conducting a carbonated water flood test on an Austin Chalk well have been identified. Feasibility studies are presently underway.

    Groundbased UV/Vis-spectroscopy of zenith scattered sunlight was performed at Sondre Stromfjord (Greenland) during Jan/Feb 1990 and Jan/Feb 1991. Considerable amounts of OClO were observed during both campaigns. Maximum OClO vertical column densities at 92 deg solar zenith angle (SZA) were 7.4 x 10(exp 13) molec/sq cm in 1990 and 5.7 x 10(exp 13) molec/sq cm in 1991 (chemical enhancement is included in the calculation of the air mass factor (AMF)). A threshold seems to exist for OClO detection: OClO was detected on every day when the potential vorticity at the 475 K level of potential temperature was higher than 35 x 10(exp -6)Km(exp 2)kg(exp -1)s(exp -1). NO2 vertical columns lower than 1 x 10(exp 15) molec/sq cm were frequently observed in both winters.

Reagents included low-valent metal complexes based on nickel and on iron as well as possible Single Electron Transfer reagents. Soluble coal extracts served as second generation model compounds during this reagent development project.

    Based on initial bombardment studies we have previously concluded that promoter diversity was responsible for the diversity of naturally occurring R alleles. During this period we have found that R is controlled at the level of translation initiation and intron 1 is alternatively spliced. The experiments described in Sections 1 and 2 sought to quantify these effects and to determine whether they contribute to the tissue specific expression of select R alleles. This study was done because very little is understood about the post-transcriptional regulation of plant genes. Section 3 and 4 describe experiments designed to identify important structural components of the R protein.

    During the last grant period, we have completed studies on the key pathways of monoterpene biosynthesis and catabolism in sage and peppermint, and have, by several lines of evidence, deciphered the rate-limiting step of each pathway. We have at least partially purified and characterized the relevant enzymes of each pathway. We have made a strong case, based on analytical, in vivo, and in vitro studies, that terpene accumulation depends upon the balance between biosynthesis and catabolism, and provided supporting evidence that these processes are developmentally-regulated and very closely associated with senescence of the oil glands. Oil gland ontogeny has been characterized at the ultrastructural level. We have exploited foliar-applied bioregulators to delay gland senescence, and have developed tissue explant and cell culture systems to study several elusive aspects of catabolism. We have isolated pure gland cell clusters and localized monoterpene biosynthesis and catabolism within these structures, and have used these preparations as starting materials for the purification to homogeneity of target ``regulatory`` enzymes. We have thus developed the necessary background knowledge, based on a firm understanding of enzymology, as well as the necessary experimental tools for studying the regulation of monoterpene metabolism at the molecular level. Furthermore, we are now in a position to extend our systematic approach to other terpenoid classes (C{sub 15}-C{sub 30}) produced by oil glands.

    The development of new methods for the production of complex materials is one of the most important problems in modern solid state chemistry and materials science. This project is attempting to apply the synthetic principles which have evolved inorganic and organometallic chemistry to the production of technologically important non-oxide ceramics, such as boron nitride, boron carbide and metal borides. Our recent work has now resulted in the production of new polymer systems, including poly(B-vinylborazine), polyvinylpentaborane and polyborazylene, that have proven to be high yield precursors to boron-based ceramic materials. Current work is now directed toward the synthesis of new types of molecular and polymeric boron-containing species and on exploration of the solid state properties of the ceramics that have been produced in these studies.

    West Virginia University has designed and constructed a Transportable Emissions Testing Laboratory for measuring emissions from heavy duty vehicles, such as buses and trucks operating on conventional and alternative fuels. The laboratory facility can be transported to a test site located at, or nearby, the home base of the vehicles to be tested. The laboratory has the capability of measuring vehicle emissions as the vehicle is operated under either transient or steady state loads and speeds. The exhaust emissions from the vehicle is sampled and the levels of the constituents of the emission are measured. The laboratory consists of two major units; a power absorber unit and an emissions measurement unit. A power absorber unit allows for the connection of a dynamic load to the drive train of the vehicle so that the vehicle can be ``driven`` through a test cycle while actually mounted on a stationary test bed. The emissions unit contains instrumentation and equipment which allows for the dilution of the vehicle`s exhaust with air. The diluteed exhaust is sampled and analyzed to measure the level of concentration of those constituents which have been identified to have impact on the clean environment. Sampling probes withdraw diluted exhaust which is supplied to a number of different exhaust gas analysis instruments. The exhaust gas analysis instruments have the capability to measure the levels of the following exhaust gas constituents: carbon monoxide (CO), carbon dioxide (CO{sub 2}), oxides of nitrogen (NO{sub x}), unburned hydrocarbons (HC), formaldehyde (HCHO), methane and particulate matter. Additional instruments or sampling devices can be installed whenever measurements of additional constituents are desired. A computer based, data acquisition system is used to continuously monitor a wide range of parameters important to the operation of the test and to record the test results.

    We have continued our meteorological and hydrologic data collection in support of our process-oriented research. The six years of data collected to date is unique in its scope and continuity in a North Hemisphere Arctic setting. This valuable data base has allowed us to further our understanding of the interconnections and interactions between the atmosphere/hydrosphere/biosphere/lithosphere. The increased understanding of the heat and mass transfer processes has allowed us to increase our model-oriented research efforts. Examples of applications are the following. (1) Spring snowmelt on the North Slope of Alaska is the dominant hydrologic event of the year. This event provides most of the moisture for use by vegetation in the spring and early summer period. The mechanisms and timing of snowmelt are important factors in predicting runoff, the migrations of birds and large mammals and the diversity of plant communities. It is important globally due to the radical and abrupt change in the surface energy balance over vast areas. (2) We were able to explore the trends and differences in the snowmelt process along a transect from the Brooks Range to the Arctic Coastal plain. Snowpack ablation was monitored at three sites. These data were analyzed along with meteorologic data at each site. The initiation of ablation was site specific being largely controlled by the complementary addition of energy from radiation and sensible heat flux.

    This report provides background information and instructions to assist applicants in writing Energy-Related Inventions Program (ERIP) applications. Initial feedback fro usage for the new instructions shows that the best instructions would not be read and followed by all applicants. Applications from more than thirty applicants who have received the new instructions indicated that few had read the instructions. Based on this feedback, the instructions have been further revised to include a title page and table of contents. A warning was also added to advise applicants of the potential penalty of delayed review if these instructions are not followed. This revision was intended to address the possibility that some applicants did not see or bother to follow the instructions which followed the background information about ERIP. Included are two examples of ERIP applications which have been prepared for handout at workshops or mailing to applicants. Writing of example applications was time consuming and more difficult than expected for several reasons: (1) Full disclosures can be lengthy, very detailed, and technical. This contrasts with the desire to prepare examples which are comparatively short and easy for the non-technical person to read. (2) Disclosures contain confidential information which should not be published. (3) It is difficult to imagine that applicants will study examples when they do not bother to read the basic instructions.

  12. Oil recovery enhancement from fractured, low permeability reservoirs. Annual report 1990--1991, Part 1

    1991-12-31

    Joint funding by the Department of Energy and the State of Texas has Permitted a three year, multi-disciplinary investigation to enhance oil recovery from a dual porosity, fractured, low matrix permeability oil reservoir to be initiated. The Austin Chalk producing horizon trending thru the median of Texas has been identified as the candidate for analysis. Ultimate primary recovery of oil from the Austin Chalk is very low because of two major technological problems. The commercial oil producing rate is based on the wellbore encountering a significant number of natural fractures. The prediction of the location and frequency of natural fractures at any particular region in the subsurface is problematical at this time, unless extensive and expensive seismic work is conducted. A major portion of the oil remains in the low permeability matrix blocks after depletion because there are no methods currently available to the industry to mobilize this bypassed oil. The following multi-faceted study is aimed to develop new methods to increase oil and gas recovery from the Austin Chalk producing trend. These methods may involve new geological and geophysical interpretation methods, improved ways to study production decline curves or the application of a new enhanced oil recovery technique. The efforts for the second year may be summarized as one of coalescing the initial concepts developed during the initial phase to more in depth analyses. Accomplishments are predicting natural fractures; relating recovery to well-log signatures; development of the EOR imbibition process; mathematical modeling; and field test.

    The removal of biofouling from vessels during hull cleaning can pose a biosecurity threat if viable, non-indigenous organisms are released into the aquatic environment. However, the effect of cleaning on biofouling organism viability in different types of cleaning operations has been poorly studied. We compared the effects of hull cleaning on biofouling organisms removed from 36 marine vessels during in-water (without capture of cleaning waste) and shore-based (with capture, and treatment of cleaning waste) cleaning. In-water cleaning resulted in higher proportions of viable biofouling organisms surviving cleaning (62.3 ± 7.1% of all organisms examined) compared to dry dock (37.8 ± 8.6%) and haul-out (20.1 ± 5.3%) operations. For shore-based facilities with effluent treatment systems, concentrations of organisms and/or their propagules in cleaning effluent was reduced by ≥ 98.5% compared to initial hydro-blast effluent concentrations. These results can be used in guidance for hull cleaning operations to minimize associated biosecurity risk. Copyright © 2012 Elsevier Ltd. All rights reserved.

  15. No broad-based energy taxes in 1991 budget

    This article discusses energy taxes in 1991 budget. On September 30, less than 12 hours before automatic across-the-board budget cuts were to go into effect at the start of a new fiscal year, President Bush announced that congressional negotiators had agreed upon a budget package for FY 1991. At press time, Congress had not voted on the measure, but was expected to do so soon. Utility industry groups were happy that the much-talked-about broad-based energy tax - on Btu's or carbon emissions - was missing. The gasoline tax, however, currently nine cents a gallon, is due for two five-cent increases, on December 1 and July 1. Petroleum-based products - excluding home heating oil, but including gasoline - would be taxed an additional two cents on January 1. Expected revenues from the two taxes: $56.8 billion in five years.

    Bacterial kidney disease (BKD), caused by Renibacterium salmoninarum (RS), a serious disease of salmonid fish worldwide. The disease has a major impact on spring chinook salmon populations in the Columbia River system. There is strong evidence that RS can be transmitted from parent to progeny, and segregation of progeny based on levels of antigen detected in adult fish may obviate this mode of transmission. Results are presented from the third year of a four year study to investigate segregation of broodstock as a tool for controlling BKD. Segregation of adult fish infected with RS has been achieved using enzyme-linked immunosorbent assays (ELlSAs) optimized in the first and second year of this project. Gametes from both 1990 and 1991 broodstock, either injected with erythromycin or receiving no antibiotic injection were successfully segregated into groups having either high or low levels of the RS soluble antigen. Offspring have been monitored every three months from the 1990 broodstock and are being monitored from the 1991 broodstock. Antigen levels in the offspring from the 1990 segregation experiment at Marion Forks Hatchery were low and clinical BKD was not observed in any of the juvenile fish. At Carson National Fish Hatchery, antigen levels were also low in fish which were sampled December 1990 through July 1991. Total mortality was low throughout these sampling periods. An increase in mortality was observed in November-December 1991, and preliminary evidence suggests that motality may have been due BKD. The epizootic appears to have equally effected both offspring from high and low RS antigen level parents. Antigen levels in moribund fish are being examined to confirm the prevalence of RS infection.

    Carlson and Kingston ([2007]: Am J Hum Biol 19:132-141) propose that preformed dietary docosahexaenoic acid (an omega-3 fatty acid in fish) did not have a significant role in hominin encephalization. Their position hinges on claiming that humans are able to make sufficient docosahexaenoic acid from the plant-based "parent" omega-3 fatty acid-alpha-linolenic acid. They also suggest that hominin fish consumption occurred too late to have materially influenced encephalization. The authors quantify here a summary of the published data showing that humans cannot make sufficient docosahexaenoic acid to maintain normal infant brain development. The authors also provide evidence that the fossil record shows that some of the earliest hominins were regularly consuming fish. Hence, we reject Carlson and Kingston's position and reiterate support for the concept that access to shore-based diets containing docosahexaenoic acid was necessary for hominin encephalization beyond the level seen in the great apes.

    We report on our effort from April 1990 to March 1991 to describe the life history and population dynamics of white sturgeon Acipenser transmontanus in.John Day Reservoir. We set 1188 set lines and 26 gill nets. We caught 623 white sturgeon with set lines and 236 with gill nets. Catch per unit effort was much higher in areas near the tailrace than in downstream sites. Our setlines were size selective. We recaptured 3 fish released in John Day Reservoir in 1989 and 28 fish released in 1990. Sport and commercial fishermen recovered 62 tags from fish we tagged in Bonneville, The Dalles and John Day reservoirs, 1987-1990. We observed extensive movements of marked sturgeon within the reservoirs. We completed aging of available samples from all three reservoirs from 1987-1990. We aged fish as old as 46 years. Bone marks were observed on 74 of 78 fish previously injected with oxytetracycline and annulus formation was generally complete after June. We estimated parameters in a length-weight equation. About 1.5% of the female white sturgeon we examined to date had early or late vitellogenic eggs and would be expected to spawn the following year.

    The report evaluates evapotranspiration at four grassland sites in eastern Washington: the Snively Basin and grass lysimeter sites on the Arid Lands Ecology Reserve, and the meadow and marsh sites on the Turnbull National Wildlife Refuge. A combination of the Bowen-ratio and Penman-Monteith methods were used to estimate evapotranspiration at the sites from May 30, 1990 to September 30, 1991. The Bowen-ratio method could be used to estimate latent-heat flux during only parts of the study period. Latent heat-flux values during these periods were used in the Penman-Monteith method to estimate canopy resistance. The daily average resistance values were used to recalculate latent-heat-flux with the Penman-Monteith method for all periods. Evapotranspiration estimates made with the two methods agreed within 3 percent over the period of study. However, for the grass lysimeter site, evapotranspiration estimates made with the Bowen-ratio method were only 41 percent of those made with weighing lysimeters. A water budget from August 20, 1990 to September 30, 1991 at the Snively Basin site estimated that 101 percent of the precipitation was returned to the atmosphere as evapotranspiration. Sixteen percent of the evapotranspiration occurred from October to February, while 76 percent occurred from March to July. April accounted for over 25 percent of the evapotranspiration for the water budget period.

    A hydrologic investigation to define the water quality of Corydon Reservoir before implementation of agricultural best-management practices in the basin was conducted from September 1990 to September 1991. Runoff from the 1,680-acre basin is the primary source of water to the 58-acre reservoir. Current water quality of the reservoir is affected substantially by runoff from the agricultural basin. Total-solids, total-nitrogen, and total-phosphorus concentrations were largest during April through July 1991, the months of greatest rainfall. Herbicide concentrations increased substantially in June after application. The concentration of the sum of all triazines was greater than 50 micrograms per liter in one sample, with the predominant herbicides being atrazine and cyanazine. Atrazine concentrations, estimated from immunoassay, were greater than 8.0 micrograms per liter from June through September 1991 as a result of reservoir storage. Atrazine concentrations commonly were less at the surface than at depth. Algal populations remained constant even though nutrient concen- trations increased during the summer months. This may be due to the presence of suspended sediment that reduces light penetration and herbicides that inhibit photosynthesis.

    The purpose of this study was to determine whether proportional cancer incidence is greater among Gulf War veterans compared with non-Gulf War veterans. Files obtained from the Defense Manpower Data Center included data for 621,902 veterans who were deployed to the Persian Gulf during the 1990 to 1991 Gulf War (August 2, 1990, to March 1, 1991) and 746,248 non-Gulf War veteran controls. Identification of veterans who received a cancer diagnosis between 1991 and 2006 was accomplished through record linkage of the Defense Manpower Data Center dataset with files from 28 state cancer registries and the Department of Veterans Affairs Central Cancer Registry. By the use of logistic regression, proportional incidence ratios adjusted for demographic and military characteristics were calculated by comparing the proportion of a specific cancer among all cancers in the Gulf War veterans to the proportion of that specific cancer among all cancers in the non-Gulf War veterans. Only lung cancer showed a statistically significant relative excess among Gulf War veterans compared with non-Gulf War veterans (adjusted proportional incidence ratios, 1.15; 95% confidence interval, 1.03-1.29). When adjusted for race, age, and sex, the overall proportion of cancers among Gulf War and non-Gulf War veterans was similar (odds ratio, 0.99; 95% CI, 0.96-1.02). With the exception of lung cancer, there is little evidence of excess risk of cancer associated with Gulf War deployment. A follow-up study is warranted to confirm this finding and to evaluate the role of greater smoking rates among deployed personnel. Copyright (c) 2010 Elsevier Inc. All rights reserved.

Water samples were collected for the laboratory analysis of major and minor ions (calcium, magnesium, sodium, potassium, strontium, chloride, sulfate, silica as SiO2), trace elements (aluminum, arsenic, boron, barium, beryllium, cadmium, cobalt, chromium, copper, iron, lead, lithium, manganese, molybdenum, nickel, selenium, thallium, uranium, vanadium and zinc), and nutrients (phosphate, nitrate, ammonium, nitrite, total dissolved nitrogen, total dissolved phosphorus and dissolved organic carbon). Biological measurements included drift (benthic invertebrates and detrital material), and benthic invertebrates from the river bottom.

    This study has been planned in order to determinate the frequency of the infection by VIH among the 394 new tuberculous, for a period extended from July 1990 to July 1991 at the section of pneumophtisiology in the National Hospital of Niamey. The number of seropositives is 7.6%. The two types of viruses, i.e. VIH1 and VIH2, and the double infection by VIH1 + VIH2 types exist in the tuberculous patients. The VIH1 is most frequently found in the subjects of age group 20-39 years, who are almost emigrants. Inspite of the actual weak sero-prevalency among the tuberculous patients, the authors claim that a sero-epidemiological sequential survey of tuberculosis in Niamey can be a relatively easy method for measuring the variations of sero-prevalency of AIDS in Niger.

    1984-09-01

    A 1982 study of a 10 MWe shore-based closed-cycle ocean thermal energy conversion (OTFC) plant at Keahole Point, Hawaii, is updated to reflect advances in technology that have occurred over the past two years. Design options that show promise for reducing the capital cost of the plant are presented. The options studied include the heat exchangers, the number and size of the cold-water pipes (CWP), the materials and method of construction of the CWP, deployment technique. In all cases, the new options are within modest extrapolations of the current state of the art. Thermal-hydraulic optimization codes were developed and used to upgrade and improve the design, and to focus on those components where significant cost reductions are possible. The power system was improved with more cost-effective heat exchangers and a more water-efficient design. An advanced cold-water pipe option was selected that uses compact, brazed-aluminum heat exchangers. Options for parallel or bundled pipes of smaller (2 meter) diameter were reviewed. It was found that the smaller diameters present fewer fabrication problems, and potentially simpler deployment methods. Also studied were various options for CWP materials and construction.

    This NDP presents land-based monthly surface-air-temperature anomalies (departures from a 1951-1970 reference period mean) on a 5° latitude by 10° longitude global grid. Monthly surface-air-temperature anomalies (departures from a 1957-1975 reference period mean) for the Antarctic (grid points from 65°S to 85°S) are presented in a similar way as a separate data set. The data were derived primarily from the World Weather Records and from the archives of the United Kingdom Meteorological Office. This long-term record of temperature anomalies may be used in studies addressing possible greenhouse-gas-induced climate changes. To date, the data have been employed in producing regional, hemispheric, and global time series for determining whether recent (i.e., post-1900) warming trends have taken place. The present updated version of this data set is identical to the earlier version for all records from 1851-1978 except for the addition of the Antarctic surface-air-temperature anomalies beginning in 1957. Beginning with the 1979 data, this package differs from the earlier version in several ways. Erroneous data for some sites have been corrected after a review of the actual station temperature data, and inconsistencies in the representation of missing values have been removed. For some grid locations, data have been added from stations that had not contributed to the original set. Data from satellites have also been used to correct station records where large discrepancies were evident. The present package also extends the record by adding monthly surface-air-temperature anomalies for the Northern (grid points from 85°N to 0°) and Southern (grid points from 5°S to 60°S) Hemispheres for 1985-1990. In addition, this updated package presents the monthly-mean-temperature records for the individual stations that were used to produce the set of gridded anomalies. The periods of record vary by station. Northern Hemisphere data have been corrected for inhomogeneities

    The spent nuclear fuel (SNF) and radioactive waste (RAW) storage facility at Andreeva Bay shore technical base (STB) is one of the largest and most hazardous nuclear legacy sites in northwest Russia. Originally commissioned in the 1960s the facility now stores large amounts of SNF and RAW associated with the Russian Northern Fleet of nuclear powered submarines. The objective of the present study was to map ambient gamma dose rates throughout the facility, in particular at a number of specific sites where SNF and RAW are stored. The data presented here are taken from a Norwegian-Russian collaboration enabling the first publication in the scientific literature of the complete survey of on-site dose rates. Results indicate that elevated gamma dose rates are found primarily at discrete sites within the facility; maximum dose rates of up to 1000 microSv/h close to the ground (0.1m) and up to 3000 microSv/h at 1m above ground were recorded, higher doses at the 1m height being indicative primarily of the presence of contaminated equipment as opposed to ground contamination. Highest dose rates were measured at sites located in the immediate vicinity of buildings used for storing SNF and sites associated with storage of solid and liquid radioactive wastes. Elevated dose rates were also observed near the former channel of a small brook that became heavily contaminated as a result of radioactive leaks from the SNF storage at Building 5 starting in 1982. Isolated patches of elevated dose rates were also observed throughout the STB. A second paper detailing the radioactive soil contamination at the site is published in this issue of Journal of Environmental Radioactivity.

    The Texas A&M experimental high energy physics program has been supported since its inception by DOE Contract DE-AS05-81ER40039. During that period we established a viable experimental program at a university which before this time had no program in high energy physics. In 1990, the experimental program was augmented with a program in particle theory. In the accompanying final report, we outline the research work accomplished during the final year of this contract and the program being proposed for consideration by the Department of Energy for future grant support. Some of the particular areas covered are: Collider detector at Fermilab program; the TAMU MACRO program; SSC R&D program; SSC experimental program; and theoretical physics program.

    The major elements of this project continues to be on fundamental symmetries and parameters of the Standard Model. The projects in the current period have been BNL E791 (a search for the decay K{sub L}{sup 0} {yields} {mu}e, which would violate the rule of separate lepton number conservation), test of an upgrade proposal (E871), and LSND, a neutrino experiment at LAMPF. For E791, data taking was completed in June 1990, and preliminary results are now available for the decays K{sub L}{sup 0} {yields} {mu}e and K{sub L}{sup 0} {yields} {mu}{mu}from the entire data set. The data for decay K{sub L}{sup 0} {yields} ee are still being analysed. These are an upper limit for the branching fraction for K{sub L}{sup 0} {yields} {mu}e of 3.5 {times} 10{sup {minus}11} (90% C.L.). From the 1990 data alone, we have a new (preliminary) value of the branching fraction for K{sub L}{sup 0} {yields} {mu}{mu} of (6.96{plus_minus}0. 4{plus_minus}0.22) {times} 10{sup {minus}9}, with a sample of 349 events. Combining this with earlier data gives (6.96{plus_minus}0.34) {times} 10{sup 9}, by far the most precise value. The limit on the decay K{sub L}{sup 0} {yields} {mu}e places a lower limit on the mass of a new particle mediating such decays of 85 TeV. The LSND (Large Scintillator Neutrino Detector), a search for neutrino oscillations at LAMPF, has been approved, and is now underway. Other neutrino work at Los Alamos, E764, has resulted in a final publication. This includes the best, measurement of {nu}-nuclear scattering, in {nu}{sub mu} {sup 12}C inclusive cross sections. The measurement of the cross section for the exclusive reaction {nu}{sup mu}{sup 12}C {yields} {mu}{sup {minus}12} N is unique. In a new development, Dr. Martoff has established a facility for fabrication of superconducting detectors of nuclear radiation; the equipment has been funded and is partly installed. Planned uses include scattering for `Dark Matter.` In summary, the objectives for this year have been met.

    Large outbreaks of diphtheria occurred recently in the former USSR. Between 1989 and 1994, a total of about 600,000 Soviet immigrants arrived in Israel. The immune status against diphtheria in a sample of 992 men aged 17-49 and 195 women aged 17-19, who arrived in Israel during 1990-91, was studied in order to evaluate the need for vaccination. Participants completed a self-administered questionnaire and diphtheria antitoxin antibody levels were measured by means of ELISA. At age 17-19, the prevalence of antitoxin antibody levels below the protective level of 0.01 IU/ml was 4.8% in the men and 2.1% in the women. Among the men, the percentage lacking protection declined from 4.8% at age 17-19 years to 1.6% at age 20-24, and increased to 18.2% at age 35-49. In the oldest group, the prevalence of those lacking protection was considerably higher than for the general Israeli population. In the multivariate analysis, age, mother's education and republic of origin were significantly associated with the absence of protection. Immigrants from the former USSR appear to be more susceptible to diphtheria, thus increasing the possibility of clinical disease, and it is recommended that they receive booster doses of diphtheria toxoid.

    With the increased emphasis by Department of Energy personnel on assessing the environmental impact of past waste disposal practices at all of its facilities, there has been an associated increase in characterization activities that focus on delineating site-specific groundwater flow regimes and contaminant migration pathways. At the Oak Ridge Y-12 Plant, the complex geologic and hydrologic relationships require a more detailed understanding of the three-dimensional properties of groundwater flow regimes than can be obtained by conventional monitoring activities. Thus, as part of groundwater characterization activities conducted by the Environmental Surveillance Section staff of the Y-12 Plant Environmental Management Department, five existing deep core holes were instrumented with multiport monitoring systems to provide greatly enhanced resolution of the hydraulic and hydrochemical properties of the groundwater system within Bear Creek Valley. With a multiport system, it is possible to measure hydraulic head and hydraulic conductivity and collect water samples from multiple levels within a single borehole. In this report, multiport data collected during fiscal years (FYs) 1990 and 1991 are summarized.

    We report on our effort from October 1990 through March 1991 to prepare for the evaluation of the juvenile fish bypass facility in the West Extension Irrigation District Canal at Three Mile Falls Dam on the Umatilla River. We also report on our preliminary activities to prepare for future evaluations at Maxwell and Westland diversion dams. A detailed sampling plan was written to guide our efforts in the evaluation process and associated preparatory activities were conducted. In the sampling plan, we developed experimental designs for evaluating the passage of juvenile salmonids through the bypass system including the evaluation at design flow of injury and mortality rates, and passage of juvenile salmonids through and over the screens. We designed and fabricated fish nets for screen leakage tests, and holding facilities for test fish. Modifications to improve evaluation activities were incorporated into the collection facility, and our sampling gear. We designed and fabricated collection systems for the juvenile fish bypass facilities at Maxwell and Westland diversion dams. Preliminary monitoring of system operation was performed at Westland Diversion Dam. We offer recommendations for improving preparations and designs of future evaluations, and also recommend that a detailed evaluation of the Maxwell and Westland juvenile facilities, including evaluation of fish condition and fish passage through or over the screens, be conducted.

    The Chesapeake Bay Program is a federal-state partnership with a goal of restoring the Chesapeake Bay. Its ambient water quality monitoring programs, started in 1984, sample over 150 monitoring stations once or twice a month a month. Due to the size of the Bay watershed (64,000 square miles) and the cooperative nature of the CBP, these monitoring programs involve 10 different analytical laboratories. The Chesapeake Bay Coordinated Split Sample Program (CSSP), initialed in 1988, assesses the comparability of the water quality results from these laboratories. The report summarizes CSSP results for 1990 and 1991, its second and third full years of operation. The CSSP has two main objectives: identifying parameters with low inter-organization agreement, and estimating measurement system variability. The identification of parmeters with low agreement is used as part of the overall Quality Assurance program. Laboratory and program personnel use the information to investigate possible causes of the differences, and take action to increase agreement if possible. Later CSSP results will document any improvements in inter-organization agreement. The variability estimates are most useful to data analysts and modelers who need confidence estimates for monitoring data.

    In order to evaluate the effects on the marine ecosystem caused by an eventual discharge into sea of water based drilling fluids, as current legislation allows, chemical and ecotoxicological analyses were performed on the most common drilling muds and products used in Italian off-shore activities. The chemical analysis on drilling fluids involved the leaching test and the measurement of total content of heavy metals, whereas biodegradation tests were performed on the products used in mud's formulations. As for ecotoxicological evaluation, two marine organisms, the crustacean Artemia salina and the diatom Phaeodactylum tricornutum, were selected to determine the LC50 and the EC50 respectively.

    Perhaps the biggest impediment to the commercial application of controlled-source electromagnetic (CSEM) geophysics marine hydrocarbon exploration is the inefficiency of modeling and data inversion. If an understanding of the typical (in a statistical sense) geometrical and electrical nature of a reservoir can be attained, then it is possible to derive therefrom a simplified yet accurate model of the electromagnetic interactions that produce a measured marine CSEM signal, leading ultimately to efficient modeling and inversion. We have compiled geometric and resistivity measurements from roughly 100 known, producing off-shore Louisiana Gulf of Mexico reservoirs. Recognizing that most reservoirs could be recreated roughly from a sectioned hemi-ellipsoid, we devised a unified, compact reservoir geometry description. Each reservoir was initially fit to the ellipsoid by eye, though we plan in the future to perform a more rigorous least-squares fit. We created, using kernel density estimation, initial probabilistic descriptions of reservoir parameter distributions, with the understanding that additional information would not fundamentally alter our results, but rather increase accuracy. From the probabilistic description, we designed an approximate model consisting of orthogonally oriented current segments distributed across the ellipsoid--enough to define the shape, yet few enough to be resolved during inversion. The moment and length of the currents are mapped to geometry and resistivity of the ellipsoid. The probability density functions (pdfs) derived from reservoir statistics serve as a workbench. We first use the pdfs in a Monte Carlo simulation designed to assess the detectability off-shore Louisiana reservoirs using magnitude versus offset (MVO) anomalies. From the pdfs, many reservoir instances are generated (using rejection sampling) and each normalized MVO response is calculated. The response strength is summarized by numerically computing MVO power, and that

    The Evaluation and Improvement of NDE Reliability for Inservice Inspection of Light Water Reactors (NDE Reliability) Program at the Pacific Northwest Laboratory was established by the Nuclear Regulatory Commission to determine the reliability of current inservice inspection (ISI) techniques and to develop recommendations that will ensure a suitably high inspection reliability. The objectives of this program include determining the reliability of ISI performed on the primary systems of commercial light-water reactors (LWRs); using probabilistic fracture mechanics analysis to determine the impact of NDE unreliability on system safety; and evaluating reliability improvements that can be achieved with improved and advanced technology. A final objective is to formulate recommended revisions to the Regulatory and ASME Code requirements, based on material properties, service conditions, and NDE uncertainties.

    Our research has been directed at understanding three elementary processes that are central to developing membrane-based integrated chemical systems for water photolysis. These are: (1) the role of interfaces in charge separation/recombination reactions, (2) pathways for transmembrane charge separation, and (3) mechanisms of water oxidation catalyzed by transition metal coordination complexes. Historically, the chemical dynamics of each of these processes has been poorly understood, with numerous unresolved issues and conflicting viewpoints appearing in the literature. Our experimental systems comprise primarily unilamellar vesicles that have been doped with amphiphilic viologens which function as transmembrane charge relays. These systems are experimentally highly tractable and versatile, are conceptually simple, and have been widely used in a variety of organized microphase media and prototypic devices. As such, they are ideal for identifying basic principles governing reactivity.

    The interim report quantifies potential regional and seasonal variations in the composition and physical properties of natural gas in selected major urban areas of the United States over a one-year time period. Major urban areas were chosen because they represent a large segment of existing gas consumers and are envisioned to be a key market area for natural gas vehicles. The report lists the results of statistical analyses of gas composition in ten U.S. nonattainment cities for either ozone or carbon monoxide levels. The data are intended to provide a strong statistical basis for understanding the chemical and physical properties of natural gas in support of engine and vehicle manufacturers making equipment design and development decisions as well as related R D initiatives on gas-fired reciprocating engine technology and vehicle refueling and storage. Additional program work is underway to expand the data base to represent a total of 25 major urban areas.

    Although beach cusps are common features on beaches around the world, questions still remain regarding the range of conditions in which they form, the initial forcing conditions under which they form, and the erosive or accretionary nature of cusp events. While many prior studies have focused on the formation and morphology of beach cusps, many of these are limited in the spatial extent of observations, in their spatial or temporal resolution, or in the availability of accompanying hydrodynamic data. In this study, beach cusp formation and evolution is investigated using an automated lidar system that provides hourly three-dimensional scans of subaerial beach topography with high spatial resolution ([O(1 cm)]). The stationary lidar scanner is mounted on a 4-m tower located on the crest of a shore-backing dune on an Atlantic Ocean beach near Duck, North Carolina. The device measures a 237°-framescan of the nearshore region over a 15 minute period each hour. Individual scans are coregistered to a baseline scan using an iterative closest point (ICP) algorithm and then filtered to remove noise, dune vegetation, and water. To assess the accuracy of the coregistration algorithm, the 3-dimensional location of five permanent reflectors near the device are found for each scan and compared to their measured GPS location. Precisely coregistered scans allow for an assessment of elevation change across cuspate features in addition to traditional measurements of cusp wavelength. Beach cusp events are assessed over a three month period from September through November 2015. Wave and current data from a cross-shore array of sensors deployed continuously throughout the three month period as well as from two alongshore arrays of ADV sensors deployed from October 13 through November 1 are used to determine the forcing conditions under which the cusps formed and evolved.

    The conceptual design of a van-mounted natural gas leak detector system, based on a novel optical filter concept, was completed along with an analysis of its characteristics. The optical filter transmits optical radiation associated with the detection of methane or ethane while blocking the signal from interfering gases such as water vapor. Performance of the filter was optimized with the help of a computer program which employed high resolution spectral data of methane and ethane and water vapor in the 1.6 micrometer and 3.3 micrometer regions. A signal-to-noise calculation indicated that a double-ended system operating in the 3.3 micrometer range could detect methane concentrations as low as 1 ppm in a 1 meter pathlength while the survey vehicle is traveling at speeds up to 30 kph (20 mph). A preliminary breadboard system was assembled to confirm these predictions. The main leak detector head would be located below the front bumper of the leak survey van and connected to a central computerized data processor display and storage unit inside the van. An optional additional leak sensor head is located on an extendable side-arm which can be used to leak check along the berm of the roadway, if desired.

    A dual-screw feeder was designed for desulfurization of coal. This reactor contains two screw tubes, the inner tube acting as a coal pyrolizer and the outer tube acting as a desulfurizer with hot calcined lime pellets or other renewable sorbent pellets. The objectives of this project is to study the feasibility of an advanced concept of desulfurization and possibly some denitrification in this coal feeder. In this year, two basic studies have been performed: (1) the desulfurization and (2) the denitrification due to mild pyrolysis. Specifically, the following tasks have been performed: (1) Setting up the Dual-Screw reactor, (2) Determination of the pyrolysis product and the sulfur distribution in char, tar and gas based on experimental data, (3) Study of the devolatilization, the desulfurization kinetics and the denitrification kinetics and obtaining the basic kinetic parameters, (4) Study of the sulfur removal efficiency of lime pellets fed into the outer tube of the dual-feeder reactor, (5) Study of the effect of the coal particle size on pyrolysis and desulfurization, (6) Study of the coal pyrolysis and desulfurization using a TGA(Thermal Gravimetric Analyzer).

    The use of coal-derived synthesis gas as an industrial feedstock for production of fuels and chemicals has become an increasingly attractive alternative to present petroleum-based chemicals production. However, one of the major limitations in developing such a process is the required removal of catalyst poisons such as hydrogen sulfide (H{sub 2}S), carbonyl sulfide (COS), and other trace contaminants from the synthesis gas. Purification steps necessary to remove these are energy intensive and add significantly to the production cost, particularly for coals having a high sulfur content such as Illinois coal. A two-stage, anaerobic bioconversion process requiring little or no sulfur removal is proposed, where in the first stage the carbon monoxide (CO) gas is converted to butyric and acetic acids by the CO strain of Butyribacterium methylotrophicum. In the second stage, these acids along with the hydrogen (H{sub 2}) gas are converted to butanol, ethanol, and acetone by an acid utilizing mutant of Clostridium acetobutylicum. 18 figs., 18 tabs.

    A change in the chemical compositions of volcanic gases is one of the noticeable phenomena that frequently occurs prior to an eruption. Analysis of the water-soluble components adhering to volcanic ash is available for remote monitoring of volcanic gases from inaccessible volcanoes. It is a secure method for monitoring volcanic activity without using particular devices. Prolonged volcanic eruption at the Unzen Fugendake volcano from 1990 to 1995 started with a phreatic eruption after 198 years of dormancy. Volcanic activity changed from a phreatic and phreatomagmatic eruption to a magmatic eruption with pyroclastic flows in May 1991. The relationship between the chemical composition of volcanic ash and the contents of the water-soluble components adhering to it are discussed in relation to the early stage of the long-term eruption. Volcanic ash ejected by phreatic and phreatomagmatic eruption before dome formation was the product of the alteration in the volcanoclastic materials beneath the surface. The ash had a high content of water-soluble components, which was caused by the absorption of hydrogen chloride and sulfur dioxide gases from magma into wet debris before dome formation. Volcanic ashes which were generated by pyroclastic flows after dome formation were fresh lava fragments. While the contents of water-soluble sulfate adhering to the ash noticeably decreased, those of water-soluble chloride adhering to the ash hardly decreased. The considerable decrease in the contents of water-soluble sulfate was caused by the reaction of volcanic gases with dry lava fragments. Contrary to this, the concentration of hydrogen chloride gas in ash clouds was extremely high, which obstructed the decrease in the water-soluble chloride content in the ash. Volatility of chlorine and sulfur from volcanic rock suggests that the inner temperature of pyroclastic flows was higher than 600~700° C at least.

    The primary objective of this project is to develop an integrated database to characterize reservoir heterogeneities resulting from numerous small-scale shallowing-upward cycles (parasequences) comprising the carboniferous Pennsylvanian Wahoo Limestone. The Wahoo Limestone is the upper formation of an extensive carbonate platform sequence of the Carboniferous Lisburne Group which is widely exposed in the Brooks Range and is a widespread hydrocarbon reservoir unit in the subsurface of the North Slope of Alaska. A principal goal is to determine lateral and vertical variations in the complex mosaic of carbonate facies comprising the Wahoo Limestone. This report presents the preliminary results of research accomplished by a team of specialists in carbonate petrology, biostratigraphy, and diagenesis during the 1990--1991 fiscal year.It includes a summary of regional geological framework studies, a discussion conodont analyses, an overview of diagenetic studies, a brief description of progress in computerized database development, and appendices containing some of the new data on petrographic analyses, conodont analyses, and locality and sample information. Our correlation scheme, which uses cyclic stratigraphy, biostratigraphy, and cement stratigraphy, will allow interpretation of the depositional history and paleogeographic evolution of the region. We have developed predictive facies models and will make paleogeographic maps to illustrate different stages in the history of the Wahoo carbonate ramp. Our detailed analyses of the Wahoo Limestone will provide a basis for interpreting correlative rocks in the adjacent subsurface of the coastal plain of ANWR, a potential hydrocarbon lease-sale area. In a broader sense, our work will provide an excellent generic example of carbonate shallowing-upward cycles which typify carbonate sediments.

    This report summarizes the progress made on the project ``Growth of High {Tc} Superconducting Fibers Using a Miniaturized Laser-Heated Float Zone Process`` during the 14 month period from Nov. 6, 1990 to Dec. 31, 1991. The studies during this period focused primarily on phase diagram studies, phase relations in the calcium aluminate system and on Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} (BSCCO). Some work was also done on the Advanced Fiber Growing Station. Because of the complicated phase relationships found in the incongruently melting BSCCO system, the incongruently melting CA{sub 3}Al{sub 2}O{sub 6} phase of the calcium oxide-aluminum oxide system was studied as a model material. The data obtained was in agreement with well known solidification theory. Fibers grown from calcium oxide rich sources contained calcium oxide nodules which transported from the melting source interface to the growth interface, while those grown from aluminum oxide rich sources contained continuous inclusions of a divorced eutectic. The melt compositions were also found to follow theoretical predictions. The agreement of this data with the phase diagram and solidification theory demonstrates that phase equilibrium information can be extracted from fiber growth experiments. BSCCO feed rods were made from 12 different compositions. Fibers were grown from these rods and the melts were abruptly quenched which preserves the as-grown 2212 fiber, a glassy frozen melt and the source. A future study of these sections will reveal the phase relationships that exist in the BSCCO system. Melt temperature gradients of 500--1,000 C/cm were measured near the interface in these experiments. During this reporting period, work continued on the mechanical components of the Advanced Fiber Growth Station.

  9. Sulfur evolution of the 1991 Pinatubo magmas based on apatite

    The 1991 eruptions of Mt. Pinatubo, Philippines, were triggered by basaltic recharge into the 50 km3 dacitic magma reservoir, and released 20 million tonnes of SO2 into the stratosphere. Three primary juvenile products erupted: dacite, hybrid andesite, and basaltic inclusions. Sulfur bearing apatites occur in all three juvenile components, yet observed S content is variable. Basaltic magma includes only high-S (>0.7 wt.% SO3) apatites, while dacitic and hybrid andesitic magmas carry low- (<0.3 wt.% SO3), med.- (0.3-0.7 wt.% SO3), and high-S apatites. Pre-eruption conditions (~780°C, 220 MPa, NNO+1.7, and 77 ppm S) (Rutherford & Devine, 1996; Scaillet & Evans, 1999) and a partition coefficient of 13 (Baker & Rutherford, 1996) could yield only low-S apatite containing up to 0.25 wt.% SO3, which is consistent with the SO3 concentrations found in large (≤200 μm) apatite microphenocrysts in glass. Med.-S apatite would still be consistent with pre-eruption conditions if melt sulfur was once at the solubility maximum of ~350 ppm (cf., Clemente et al., 2004). However, concentrations of SO3 in nearly 30% of dacite-hosted apatites analyzed exceeded 0.7 wt.%, which is much higher than can be achieved through apatite/melt equilibrium partitioning. Such high-S apatite of dacite occur only as inclusions in other phenocrysts (anhydrite, plagioclase, hornblende, and Fe-Ti oxide) and were likely generated during conditions leading to accumulation of the pre-eruptive, separate S gas phase responsible for the "excess sulfur" at Pinatubo. Other explanations, such as inheritance from mafic magmas or diffusional exchange with closely associated anhydrite, can be ruled out. Evidence against the former is found in distinct crystal populations based on major (e.g. Mg, Cl) and trace elements (e.g. total REE, Eu/Eu*, Sr), separating "silicic" apatites (i.e. those hosted in dacite or andesite, irrespective of S content) from basalt apatites.

    We describe in this paper the modifications, improvements, and enhancements to the HITRAN molecular absorption database that have occurred in the two editions of 1991 and 1992. The current database includes line parameters for 31 species and their isotopomers that are significant for terrestrial atmospheric studies. This line-by-line portion of HITRAN presently contains about 709,000 transitions between 0 and 23,000/cm and contains three molecules not present in earlier versions: COF2, SF6, and H2S. The HITRAN compilation has substantially more information on chlorofluorocarbons and other molecular species that exhibit dense spectra which are not amenable to line-by-line representation. The user access of the database has been advanced, and new media forms are now available for use on personal computers.

    A project to study San Francisco Bay sediments collected over 300 sediment gravity cores; six push cores, and three box cores in San Francisco Bay during the years 1990-91. The purpose of the sampling effort is to establish a database on the Holocene sediment history of the bay. The samples described and mapped are the first effort to catalog and present the data collected. Thus far the cores have been utilized in various cooperative studies with state colleges and universities, and other USGS divisions. These cores serve as a base for ongoing multidisciplinary studies. The sediment studies project has initiated subsequent coring efforts within the bay using refined coring techniques to attain deeper cores.

    Most U.S. Navy ships operate without embarked physicians, employing Independent Duty Corpsmen to provide primary and emergency medical care to crewmembers. We sought to characterize the burden of chronic disease faced by Independent Duty Corpsmen aboard Navy ships and compare it to that of a similar shore-based population. We conducted cross-sectional analyses of shipboard and shore-based samples using 1,305 records from Norfolk, Virginia-based U.S. Navy ships without doctors between March and May 2007, and records for Norfolk shore-based sailors from the same time frame matched 3:1 on age, sex, and race against the shipboard sample. Asthma prevalence was 2.0% and 5.9% for the shipboard and shore-based samples, respectively (p < 0.0001). Cervical dysplasia among women was 16.2% and 23.1% (p = 0.3687). Depression was 4.6% and 8.4% (p < 0.0001). Diabetes was 1.0% and 2.3% (p = 0.0096). Hyperlipidemia was 20.6% and 21.4% (p = 0.5597). Hypertension was 25.5% and 36.1% (p < 0.0001). Total prevalence for any of the above conditions was 42.5% and 50.9% (p = 0.0001). Over 42% of shipboard sailors have one or more chronic health conditions. Even though the studied conditions were significantly less prevalent aboard ship than in the comparable shore-based sample, nonphysician practitioners aboard ships must be prepared to diagnose and treat chronic diseases.

    The Pittsburgh Energy Technology Center of the US Department of Energy has contracted with Combustion Engineering, Inc. (CE) to perform a three-year project on ``Combustion Characterization of Beneficiated Coal-Based Fuels.`` The beneficiated coals are produced by other contractors under the DOE Coal Preparation Program. Several contractor-developed advanced coal cleaning processes are being run at the cleaning facility in Homer City, Pennsylvania, to produce 20-ton batches of fuels for shipment to CE`s laboratory in Windsor, Connecticut. CE then processes the products into either a coal-water fuel (CVVT) or a dry microfine pulverized coal (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. The technical approach used to develop the technical data includes: bench-scale fuel property, combustion, and ash deposition tests; pilot-scale combustion and ash effects tests; and full-scale combustion tests. Subcontractors to CE to perform parts of the test work are the Massachusetts Institute of Technology (MIT), Physical Science, Inc. Technology Company (PSIT) and the University of North Dakota Energy and Environmental Research Center (UNDEERC). Twenty fuels will be characterized during the three-year base program: three feed coals, fifteen BCFS, and two conventionally cleaned coals for full-scale tests. Approximately, nine BCFs will be in dry microfine coal (DMPC) form, and six BCFs will be in coal-water fuel (CWF) form. Additional BCFs would be characterized during optional project supplements.

  4. A Novel Approach to Mapping Intertidal Areas Using Shore-Based X-band Marine Radar

    Monitoring the morphology of coastal zones in response to high energy weather events and changing patterns of erosion and deposition over time is vital in enabling effective decision-making at the coast. Common methods of mapping intertidal bathymetry currently include vessel-based sonar and airborne LiDAR surveys, which are expensive and thus not routinely collected on a continuous basis. Marine radar is a ubiquitous technology in the marine industry and many ports operate a system to guide ships into port, this work aims to utilise this already existing infrastructure to determine bathymetry over large intertidal areas, currently up to 4 km from the radar. Standard X-band navigational radar has been used in the marine industry to measure hydrodynamics and derive bathymetry using empirical techniques for several decades. Methods of depth mapping thus far have relied on the electromagnetic backscattering from wind-roughened water surface, which allows a radar to gather sea surface image data but requires the waves to be clearly defined. The work presented here does not rely on identifying and measuring these spatial wave features, which increases the robustness of the method. Image data collected by a 9.4Ghz Kelvin Hughes radar from a weather station on Hilbre Island at the mouth of the River Dee estuary, UK were used in the development of this method. Image intensity at each pixel is a function of returned electromagnetic energy, which in turn can be related to the roughness of the sea surface. Images collected over time periods of 30 minutes show general patterns of wave breaking and mark the advance and retreat of the waterline in accordance with the tidal cycle and intertidal morphology. Each pixel value can be extracted from these mean images and analysed over the course of several days, giving a fluctuating time series of pixel intensity, the gradient of which gives a series of pulses representing transitions between wet and dry at each location.

    The fast-expanding use of social networking tools, combined with improved connectivity available through satellite-provided internet on board the scientific ocean drilling vessel JOIDES Resolution (the JR), has allowed for a whole new kind of interaction. Unlike in the not-so-distant past, when non-participants were forced to wait for months to read about the results of ongoing research, web tools allow almost instantaneous participation in ship-based ocean science. Utilizing a brand new portal, joidesresolution.org, scientists and educators at sea can post daily blogs about their work and respond to questions and comments on those blogs, update the JR’s Facebook and Twitter pages, and post videos and photos to YouTube and Flickr regularly. Live video conferencing tools also allow for direct interaction with scientists and a view into the work being done on board in real time. These tools have allowed students, teachers and families, groups and individuals on shore to follow along with the expeditions of the ship and its exciting scientific explorations -- and become a part of them. Building this community provides a whole range of rich interactions and brings seafloor research and the real process of science to those who would never before have had access to it. This presentation will include an overview of the web portal and its associated social networking sites, as well as a discussion of the challenges and lessons learned over nearly a year of utilizing these new tools.

  9. A false alarm based on electrical activity recorded at a VAN-Station in northern Greece in December 1990

    Drakopoulos, John; Stavrakakis, George N.

    A VAN-prediction was announced on January 6, 1991, through the French newspaper “Le Monde” and on January 8-10, 1991, through Greek newspapers and TV stations. We evaluate this prediction on the basis of a letter which was sent by Prof. Varotsos (without date) to the Greek Minister of Public Works, and by considering previous VAN-publications as well as recent seismological data for the candidate regions. We conclude that what was observed at ASS station (northern Greece) on December 31, 1990, was not SES-activity but another disturbance or noise.

    In June of 1990 and July of 1991, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the shallow geologic framework of the Mississippi-Alabama-Florida shelf in the northern Gulf of Mexico, from Mississippi Sound to the Florida Panhandle. Work was done onboard the Mississippi Mineral Resources Institute R/V Kit Jones as part of a project to study coastal erosion and offshore sand resources. This report is part of a series to digitally archive the legacy analog data collected from the Mississippi-Alabama SHelf (MASH). The MASH data rescue project is a cooperative effort by the USGS and the Minerals Management Service (MMS).

  11. Long-term observations of migrating shore-normal bars

    1997-01-01

    A series of migrating shore-normal sandbars with wavelengths of 50-200 m and heights of 0.5-2 m have been identified off the northern tip of Anna Maria Island, a barrier island on the west-central Florida coast. Similar features have been described elsewhere since the 1930's and termed `transverse bars.' The transverse bars identified off Anna Maria Island are found for about 3 km along the coast and extend 4 km offshore. No cusps or any other associated beach expression is evident despite the fact that the bars come to within about 75 m of the beach. Historical aerial photographs from the early 1940's through the mid 1990's provide an excellent means of quantifying the migration of the bars for this time period. The historical photographs were orthorectified resulting in errors in geographic positions of 1-2 m. Analyses of the orthorectified photos clearly show movement or migration taking place in the bar field. In the forty year period from 1951 to 1991, the southern edge of the bar field moved 200-350 m to the south, with an average migration rate of 7.9 m/yr. A current-meter deployment suggests that southerly winds associated with the passage of cold fronts drives near-bed currents to the south that are strong enough to initiate sediment transport and cause the southerly migration of the transverse bars.

    Migration statistics from the 10% sampling tabulation of the 1990 Population Census for China reflect intra and inter regional migration patterns between July 1, 1985 and June 30, 1990. Tabulations for 29 provinces provide data on inmigrants, outmigrants, interprovincial net migration, and intraprovincial migration. The provinces with inmigration 1% are Beijing (6.13%), Shanghai, Tianjin, Qinghai, Xinjiang, Hainan, Guangdong, Ningxia, Liaoning, Jiangsu, Inner Mongolia, and Jilin in descending order. The remaining provinces wer 1% with Guangxi the lowest at .37%. Provinces with 1% of out migrants were Qinghai (2.22%), Xinjiang, Hainan, Heilongjiang, Zhejiang, Jilin, Inner Mongolia, Guangxi, Sichuan, Ningxia, Gansu, Beijing, Shanghai, Hebei, and Shaanxi. The lowest of the remaining provinces with migration 1% was Guangdong (.40%). Inmingration outmigration was revealed in the following provinces: Beijing (5%), Shanghai (1%), Tianjin (1%), Guangdong (1%), Liaoning, Ningxia, Xinjiang, Jiangsu, Hainan, Fujian, Shanxi, Qinghai, Hubei, and Shandong. Outmigrants were inmigrants in Guangxi (.92%), Sichuan (.5%), Heilongjiang .5%), Zhejiang (.5%), Gansu, Hunan, Jilin, Anhui, Guizhou, Heibi, Inner Mongolia, Jiangxi, Henan, Yunnan and Shaanxi. Only 2 provinces had intra regional migration between cities and counties 3%: Guangdong (3.99%) and Qinghai.

    The paper discusses the recent incorporation of radon mitigation design recommendations in the construction of a hospital in Johnson City, TN. The recommendations resulted in the mitigation of a 5,500 square meter building with only one suction point at an incremental cost of $1.03 per square meter. Extrapolation of the pressure field extension (PFE) measurements indicates that a much larger building could have been mitigated with the system used. A search is underway for larger buildings to be built in radon prone areas of the U.S. in order to determine the effectiveness of the mitigation system in reducing radon in even larger buildings. As a prelude to the preparation of a new construction technical guidance document for schools, architectural drawings of all schools research by EPA, to date, were carefully studied to determine which building characteristics affect radon entry and ease of mitigation. Results of the study were presented at an international symposium on radon in Philadelphia, PA, in April 1991.

    Three separate tasks are included in the first year of the project. Two involve assembling data sets useful for testing radiation models in global climate modeling (GCM) codes, and the third is concerned with the development of advance instrumentation for performing accurate spectral radiation measurements. Task 1: Three existing data sets have been merged for two locations, one in the wet northeastern US and a second in the dry western US. The data sets are meteorological data from the WBAN network, upper air data from the NCDC, and high quality solar radiation measurements from Albany, New York and Golden, Colorado. These represent test data sets for those modelers developing radiation codes for the GCM models. Task 2: Existing data are not quite adequate from a modeler`s perspective without downwelling infrared data and surface albedo, or reflectance, data. Before the deployment of the first CART site in ARM the authors are establishing this more complete set of radiation measurements at the Albany site to be operational only until CART is operational. The authors will have the site running by April 1991, which will provide about one year`s data from this location. They will coordinate their measurements with satellite overpasses, and, to the extent possible, with radiosonde releases, in order that the data set be coincident in time. Task 3: Work has concentrated on the multiple filter instrument. The mechanical, optical, and software engineering for this instrument is complete, and the first field prototype is running at the Rattlesnake Mountain Observatory (RMO) test site. This instrument is performing well, and is already delivering reliable and useful information.

    Spending for health care rose to $751.8 billion in 1991, an increase of 11.4 percent from the 1990 level. National health expenditures as a share of gross domestic product increased to 13.2 percent, up from 12.2 percent in 1990. The health care sector exhibited strong growth, despite slow growth in the overall economy. This combination resulted in the largest increase in the share of the Nation's output consumed by health care in the past three decades. In this article, the authors present estimates of health spending in the United States for 1991. The authors also examine reasons for the unusually large growth in Medicaid expenditures and highlight recent trends in the hospital sector. PMID:10127445

    The KM3NeT readout concept is based on a point-to-point optical network connecting the 10,000 optical modules in the deep-sea neutrino telescope with the shore station. The numerous fiber optic channels arriving at the shore station will be concentrated on the shore electronics systems, which will receive, merge and time order the data, and send them to the DAQ system. Although the network functionality is bi-directional, the physical channel allocation is asymmetric; most channels are assigned to the data reception and only a few channels are used for control with data transport from shore to the telescope. We will discuss the FPGA based platform systems for the shore station and the appropriate firmware implementation for the data gathering and broadcast demands of a neutrino telescope. We will present our experiences based on FPGA evaluation platforms suitable to build a demonstrator of the KM3NeT shore station.

  6. Multigrain sedimentation/erosion model based on cross-shore equilibrium sediment distribution: Application to nourishment design

    NASA Astrophysics Data System (ADS)

    Li, Fangjun; Dyt, Chris; Griffiths, Cedric

    2006-05-01

    In the light of global warming and sea level rise there are many coastal beaches that suffer from erosion. Beach nourishment has become a common practice to maintain the sediment balance on a shore-face. In this paper, a three-dimensional numerical model for evaluating long-term impact of beach nourishment projects has been developed. The model addresses the longstanding complex issue of coastal morphology and sediment grain size distribution from an unconventional angle, which exploits the strong links between grain size distribution and the prevailing transport direction of each sediment constituent under 'average' wave and storm action. The present model predicts the redistribution of nourished sediment according to the subtle clues implied by equilibrium distribution curves and latest coastal wave transformation theories. After verification against recent field observations in Terschelling, The Netherlands, the model was used to predict long-term effects of different beach nourishment strategies. It was found that: (a) given the source sediment available in Terschelling the tactics of large volume and less frequent implementation are better than otherwise; and (b) from a pure engineering point of view, waterline nourishment outperforms offshore trough nourishment. The model offers an additional tool for coastal engineers to evaluate the feasibility, effectiveness and the optimization of dumping locations for beach nourishment projects. It is also a useful tool for stratigraphic modelling of shallow-marine sedimentation in conjunction with sea level changes.

  7. Characterization of the infralittoral system along the north-east Spanish coast based on sport shore-based fishing tournament catches

    2009-03-01

    Spatial and temporal variations in the structure of fish assemblages were analysed based on the catch data from a total of 2329 shore-based sport fishing tournaments held in north-eastern Spain from 2002 to 2006 with a view to characterizing the infralittoral system along 400 km of coastline and assessing the usefulness of these data as an additional means of monitoring coastal areas. A total of 63 species in 35 families were identified in the catches. Daily catch rates per fisherman varied from 0.1 kg to 0.5 kg according to the fishing area, and maximum catch rates and minimum species richness values were observed in the vicinity of the mouths of major rivers. Cluster analysis yielded six separate major groups. Two groups were characterized by predominantly or entirely rocky bottoms where the main species were Coris julis and Serranus cabrilla and were differentiated by a higher abundance of labrids and serranids and an absence of sparids. A third group encompassed areas under the influence of major rivers, where Chelon labrosus dominated the fish community. The other three groups were dominated by sparids but with differences in the total contribution by the main species, Sparus aurata, Lithognathus mormyrus, and Pagellus acarne, to each fish assemblage, indicating differences in ecological structure. The results suggest that sublittoral fish assemblages can be regarded as ecosystem descriptors and should not be overlooked as indicators of ecosystem changes. The study showed that a structured legislative framework for regulating recreational fishing tournaments can be extremely useful for monitoring littoral fishes at minimal added cost.

  10. A new and practical method to obtain grain size measurements in sandy shores based on digital image acquisition and processing

    NASA Astrophysics Data System (ADS)

    Baptista, P.; Cunha, T. R.; Gama, C.; Bernardes, C.

    2012-12-01

    Modern methods for the automated evaluation of sediment size in sandy shores relay on digital image processing algorithms as an alternative to time-consuming traditional sieving methodologies. However, the requirements necessary to guarantee that the considered image processing algorithm has a good grain identification success rate impose the need for dedicated hardware setups to capture the sand surface images. Examples are specially designed camera housings that maintain a constant distance between the camera lens and the sand surface, tripods to fix and maintain the camera angle orthogonal to the sand surface, external illumination systems that guarantee the light level necessary for the image processing algorithms, and special lenses and focusing systems for close proximity image capturing. In some cases, controlled image-capturing conditions can make the fieldwork more laborious which incurs in significant costs for monitoring campaigns considering large areas. To circumvent this problem, it is proposed a new automated image-processing algorithm that identifies sand grains in digital images acquired with a standard digital camera without any extra hardware attached to it. The accuracy and robustness of the proposed algorithm are evaluated in this work by means of a laboratory test on previously controlled grain samples, field tests where 64 samples (spread over a beach stretch of 65 km and with grain size ranging from 0.5 mm to 1.9 mm) were processed by both the proposed method and by sieving and finally by manual point count on all acquired images. The calculated root-mean-square (RMS) error between mean grain sizes obtained from the proposed image processing method and the sieve method (for the 64 samples) was 0.33 mm, and for the image processing method versus manual point counts comparison, with the same images, was 0.12 mm. The achieved correlation coefficients (r) were 0.91 and 0.96, respectively.

    The Pittsburgh Energy Technology Center of the US Department of Energy has contracted with Combustion Engineering, Inc. (CE) to perform a five-year project on ``Combustion Characterization of Beneficiated Coal-Based Fuels.`` The beneficiated coals are produced by other contractors under the DOE Coal Preparation Program. Several contractor-developed advanced coal cleaning processes are run at pilot-scale cleaning facilities to produce 20-ton batches of fuels for shipment to CE`s laboratory in Windsor, Connecticut. CE then processes the products into either a coal-water fuel (CWF) or a dry microfine pulverized coa1 (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. During the second quarter of 1991, the following technical progress was made: completed drop tube furnace devolatilization tests of the spherical oil agglomeration beneficiated products; continued analyses of samples to determine devolatilization kinetics; continued analyses of the data and samples from the CE pilot-scale tests of nine fuels; completed writing a summary topical report including all results to date on he nine fuels tested; and presented three technical papers on the project results at the 16th International Conference on Coal & Slurry Technologies.

Several contractor-developed advanced coal cleaning processes are run at pilot-scale cleaning facilities to produce 20-ton batches of fuels for shipment to CE`s laboratory in Windsor, Connecticut. CE then processes the products into either a coal-water fuel (CWF) or a dry microfine pulverized coa1 (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. During the third quarter of 1991, the following technical progress was made: Continued analyses of drop tube furnace samples to determine devolatilization kinetics; completed analyses of the samples from the pilot-scale ash deposition tests of unweathered Upper Freeport fuels; completed editing of the first three quarterly reports and sent them to the publishing office; presented the project results at the Annual Contractors` Conference.

    The industrial standard process for the purification of natural gas is to remove acid gases, mainly hydrogen sulfide and carbon dioxide, by the absorption and reaction of these gases with alkanolamines. Inadequate data for vapor -- liquid equilibrium (VLE) hinder the industry from converting operations to more energy efficient amine mixtures and conserving energy. Some energy reductions have been realized in the past decade by applying such amine systems as ``hindered`` amines, methyldiethanolamine (MDEA), and MDEA based amine mixtures. However, the lack of reliable and accurate fundamental VLE data impedes the commercial application of these more efficient alkanolamine systems. The first project objective is to improve the accuracy of vapor -- liquid equilibrium measurements at low hydrogen sulfide concentrations. The second project objective is to measure the VLE for amine mixtures. By improving the accuracy of the VLE measurements on MDEA and mixtures with other amines, energy saving can be quickly and confidently implemented in the many existing absorption units already in use. If about 25% of the existing 95.3 billion SCFD gas purification capacity is converted to these new amine systems, the energy savings are estimated to be about 3 {times} 10{sup 14} BTU/yr.

    We have constructed a scanning near-field optical microscope. For this we developed subwavelength micropipette light sources containing photostable crystal tips. We have also developed a technique for pulling and metal coating for single mode optical fibers to give nanometer silica tips emitting polarized laser light. Clear images have been obtained of polymeric porous membranes with nanometer pore sizes of comparable quality to that of scanning electron microscopy, but without the need for a vacuum. This method is aimed at both transmission and fluorescence nanoscopy. We believe that at least one of these will be operational in the coming year. We have also made significant progress on the next stage: Scanning, Tunneling, Exciton Microscopy. This is based on direct energy transfer between the tip and the particular molecule or fluorophore in the sample. We expect this stage to be operational in the third year of the project. Preliminary near-field optical scans indicate our resolution is already in the nanometer range. 3 figs. (MHB)

    Recent technical progress in molecular biology has made the mapping of entire mammalian chromosomes an attainable goal. However, a number of problems must still be overcome before genome mapping becomes rapid, efficient, and reliable. The limited size of cosmid inserts, as well as their tendency to rearrange, necessitates construction of very large libraries for mapping, due to the many gaps encountered in aligning cosmid contigs. Larger fragments can be cloned using the phage P1, but the maximum size of cloned inserts is fixed at only twice that of cosmids. The power of YACs has been demonstrated in isolating large regions of human DNA, recombining them to build up even larger regions and closing gaps in cosmid based maps. However, existing YAC libraries contain a high proportion of chimeric clones, and YACs are difficult to use for detailed mapping, often requiring recloning into cosmid sized pieces. The work has addressed some of these issues by creating an alternative and complementary approach to cloning and mapping large DNA.

    We are completing a 30-year study of the biological effects of {sup 90}Sr and {sup 226}Ra in the beagle in order to predict the possible long-term hazards to people from chronic exposure to low levels of irradiation. Animals received either radionuclide by several means of administration: (a) continual ingestion of {sup 90}Sr, (b) a single intravenous injection of {sup 90}Sr, or (c) a series of eight intravenous injections of {sup 226}Ra. Although administration of {sup 90}Sr and {sup 226}Ra ended at 540 days of age, the animals continued to receive chronic, low-level radiation doses from these bone-seeking radionuclides throughout life. This project is the largest single cohort study in beagles of internally deposited radionuclides. It is unique in use of the ingestion route for {sup 90}Sr and in exposure that began before birth and continued throughout development to adulthood with uniform labeling of the skeletons with {sup 90}Sr. The last of the dogs died in 1986 at age 18.5 years, but we are continuing to investigate the significance of these long-term exposures given at low dose rates with regard to cancer production, physiologic well-being, and shortening of life through the detailed records that were kept and by study of preserved materials. All the data have been successfully accumulated and entered into a main-frame computer data base management system. Current work is exclusively directed at preparing research papers summarizing the results and the associated biostatistical and survival analyses. 15 refs., 1 fig., 4 tabs.

    Linear instability calculations at MSFC have suggested that the Geophysical Fluid Flow Cell (GFFC) should exhibit classic baroclinic instability at accessible parameter settings. Interest was in the mechanisms of transition to temporal chaos and the evolution of spatio-temporal chaos. In order to understand more about such transitions, high resolution numerical experiments for the physically simplest model of two layer baroclinic instability were conducted. This model has the advantage that the numerical code is exponentially convergent and can be efficiently run for very long times, enabling the study of chaotic attractors without the often devastating effects of low-order trunction found in many previous studies. Numerical algorithms for implementing an empirical orthogonal function (EOF) analysis of the high resolution numerical results were completed. Under conditions of rapid rotation and relatively low differential heating, convection in a spherical shell takes place as columnar banana cells wrapped around the annular gap, but with axes oriented along the axis of rotation; these were clearly evident in the GFFC experiments. The results of recent numerical simulations of columnar convection and future research plans are presented.

  5. Defence electronics industry profile, 1990-1991

    The defense electronics industry profiled in this review comprises an estimated 150 Canadian companies that develop, manufacture, and repair radio and communications equipment, radars for surveillance and navigation, air traffic control systems, acoustic and infrared sensors, computers for navigation and fire control, signal processors and display units, special-purpose electronic components, and systems engineering and associated software. Canadian defense electronics companies generally serve market niches and end users of their products are limited to the military, government agencies, or commercial airlines. Geographically, the industry is concentrated in Ontario and Quebec, where about 91 percent of the industry's production and employment is found. In 1989, the estimated revenue of the industry was $2.36 billion, and exports totalled an estimated $1.4 billion. Strengths and weaknesses of the industry are discussed in terms of such factors as the relatively small size of Canadian companies, the ability of Canadian firms to access research and development opportunities and export markets in the United States, the dependence on foreign-made components, and international competition.

    The city of San Mateo, Calif., operates three 12- to 50-year old wastewater pumping stations on a 24-m (80-ft) wide lot located in a residential area near San Francisco Bay. Because the aging stations have difficulty pumping peak 2.19-m{sup 3}/s (50-mgd) wet-weather flows and have structural and maintenance problems, a new 2.62-m{sup 3}/s (60-mgd) station was proposed - the Dale Avenue Pumping Station - to replace the existing ones. To prevent potential damage to adjacent homes, the new station was originally conceived as a circular caisson type; however, a geotechnical investigation recommended against this type of structure because the stiff soils could make sinking the structure difficult. This prompted an investigation of possible shoring methods for the proposed structure. Several shoring systems were investigated, including steel sheeting, soldier beams and lagging, tieback systems, open excavation, and others; however, each had disadvantages that prevented its use. Because these conventional techniques were unacceptable, attention was turned to using deep soil mixing (DSM) to create a diaphragm wall around the area to be excavated before constructing the pumping station. Although this method has been used extensively in Japan since 1983, the Dale Avenue Pumping Station would be the technology's first US application. The technology's anticipated advantages were its impermeability, its fast and efficient installation that did not require tiebacks under existing homes, its adaptability to subsurface conditions ranging from soft ground to stiff clay to gravels, and its lack of pile-driving requirements that would cause high vibration levels during installation.

    The SSRL Emergency Response Shore Tool (wherein SSRL signifies Smart Systems Research Laboratory ) is a computer program within a system of communication and mobile-computing software and hardware being developed to increase the situational awareness of first responders at building collapses. This program is intended for use mainly in planning and constructing shores to stabilize partially collapsed structures. The program consists of client and server components, runs in the Windows operating system on commercial off-the-shelf portable computers, and can utilize such additional hardware as digital cameras and Global Positioning System devices. A first responder can enter directly, into a portable computer running this program, the dimensions of a required shore. The shore dimensions, plus an optional digital photograph of the shore site, can then be uploaded via a wireless network to a server. Once on the server, the shore report is time-stamped and made available on similarly equipped portable computers carried by other first responders, including shore wood cutters and an incident commander. The staff in a command center can use the shore reports and photographs to monitor progress and to consult with structural engineers to assess whether a building is in imminent danger of further collapse.

    The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of beneficiated coal-based fuels (BCFs) influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. The technical approach used to develop the technical data includes: bench-scale fuel property, combustion, and ash deposition tests; pilot-scale combustion and ash effects tests; and full-scale combustion tests. Subcontractors perform parts of the test work are the Massachusetts Institute of Technology Physical Science, Inc. Technology Company and the University of North Dakota Energy and Environmental Research Center. Twenty fuels will be characterized during the three-year base program: three feed coals, fifteen BCFs, and two conventionally cleaned coals for full-scale tests. Approximately nine BCFs will be in dry ultra fine coal (DUC) form, and six BCFs will be in coal-water fuel (CWF) form. Additional BCFs would be characterized during optional project supplements. During the third quarter of 1991, the following technical progress was made: Continued analyses of drop tube furnace samples to determine devolatilization kinetics; completed analyses of the samples from the pilot-scale ash deposition tests of three Freeport Pittsburgh 8 fuels; conducted pilot-scale combustion and ash deposition tests of a fresh batch of Upper Freeport parent coal in the CE fireside Performance Test Facility; and completed editing of the fourth quarterly report and sent it to the publishing office.

    2010-10-01

    Cross-shore surfzone tracer dispersion in a wave driven alongshore current is examined over a range of wave and current conditions with 6 continuous dye releases, each roughly 1-2 hours in duration, at Huntington Beach, California. Fluorescent dye tracer released near the shoreline formed shore parallel plumes that were sampled on repeated cross-shore transects with a jet ski mounted fluorometer. Ensemble averaged cross-shore tracer concentration profiles are generally shoreline attached (maximum at or near the shoreline), with increasing cross-shore widths and decreasing peak values with downstream distance. More than a few 100 m from the source, tracer is often well mixed across the surfzone (i.e., saturated) with decreasing tracer concentrations farther seaward. For each release, cross-shore surfzone absolute diffusivities are estimated using a simple Fickian diffusion solution with a no-flux boundary at the shoreline, and range from 0.5-2.5 m2 s-1. Surfzone diffusivity scalings based on cross-shore bore dispersion, surfzone eddy mixing length, and undertow driven shear dispersion are examined. The mixing-length scaling has correlation r2 = 0.59 and the expected best-fit slope <1, indicating that horizontal rotational motions are important for cross-shore tracer dispersion in the surfzone.

    A seasonal trend analysis of published Dobson (including stations' newly revised and Brewer-simulated Dobson) total ozone data through 1991 from a network of 56 stations has been performed, using three different data periods. The trend results for the longest data period 1964 - 1991 indicate substantial negative trends in ozone in the higher northern latitudes during the winter and spring seasons, some evidence of negative trend in the higher southern latitudes (30 deg S - 55 deg S) during all seasons, and trends close to zero for all seasons over the 30 deg S - 30 deg N latitude range. For the shortest data period, November 1978 through 1991, there is a clear indication that trends have become more negative in the higher northern latitudes, especially during the winter and spring seasons, and also in the higher southern latitudes in all seasons. A seasonal trend analysis of zonal averages of total ozone mapping spectrometer (TOMS) satellite total ozone data for the comparable period November 1978 through 1991 has also been performed, and moderately good agreement is found between trends in Dobson and TOMS data over this period.

    This technical report explains the procedures used during the 4-year production of the National Solar Radiation Data Base (NSRDB) (1961-1990). It is the second volume in a two-volume report on the NSRDB. The first volume, User's Guide-National Solar Radiation Data Base, provides the information needed to use the data base products. Volume 2 concentrates on results from the R&D required to producea solar radiation data base that would represent a significant update of a previous data base (SOLMET). More than 90% of the data in the NSRDB were estimated using a model--the Meteorological/Statistical (METSTAT) model. Much of Volume 2 concerns the METSTAT model and the sources of its input data. In addition, it contains results of comparisons of the NSRBD with the previous SOLMET data base.Results of the model evaluations and data base comparisons favor the use of NSRDB data over SOLMET data to select optimum sites and estimate performance for solar energy systems. The report noted that to improve data on solar radiation, 'measured' data need to become the mainstav of future data bases.

    Consistent forest loss estimates are important to understand the role of forest loss and deforestation in the global carbon cycle, for biodiversity studies, and to estimate the mitigation potential of reducing deforestation. To date, most studies have relied on optical satellite data and new efforts have greatly improved our quantitative knowledge on forest dynamics. However, most of these studies yield results for only a relatively short time period or are limited to certain countries. We have quantified large-scale forest loss over a 21-year period (1990-2010) in the tropical biomes of South America using remotely sensed vegetation optical depth (VOD). This passive microwave satellite-based indicator of vegetation water content and vegetation density has a much coarser spatial resolution than optical data but its temporal resolution is higher and VOD is not impacted by aerosols and cloud cover. We used the merged VOD product of the Advanced Microwave Scanning Radiometer (AMSR-E) and Special Sensor Microwave Imager (SSM/I) observations, and developed a change detection algorithm to quantify spatial and temporal variations in forest loss dynamics. Our results compared reasonably well with the newly developed Landsat-based Global Forest Change (GFC) maps, available for the 2001 onwards period (r2 = 0.90 when comparing annual country-level estimates). This allowed us to convert our identified changes in VOD to forest loss area and compute these from 1990 onwards. We also compared these calibrated results to PRODES (r2 = 0.60 when comparing annual state-level estimates). We found that South American forest exhibited substantial interannual variability without a clear trend during the 1990s, but increased from 2000 until 2004. After 2004, forest loss decreased again, except for two smaller peaks in 2007 and 2010. For a large part, these trends were driven by changes in Brazil, which was responsible for 56 % of the total South American forest loss area over our study

    A method was developed for simultaneous analysis of perfluoroalkane sulfonic acids (PFSAs) and their sulfonamide-based precursors (perfluoroalkane sulfonamidoacetic acids (FASAAs), sulfonamides (FASAs), and sulfonamidoethanols (FASEs)) in fish muscle. Extraction was performed with acetonitrile followed by a clean-up and fractionation step and instrumental analysis by UPLC/MS/MS and GC/MS. Time trends of PFSAs and their precursors in herring muscle samples originating from the Kattegat at the west coast of Sweden were investigated covering the years 1991-2011. The following analytes were detected, all with decreasing or unchanged trends between 1991 and 2011: Perfluorobutane sulfonic acid (PFBS, below the method detection limit (1990s. Isomer-specific analysis of PFOS and FOSA revealed <10% relative contributions of branched isomers to total PFOS and total FOSA. Furthermore, the percentage branched isomers decreased over time for both compounds. These findings are contrary to patterns and temporal trends of PFOS isomers commonly found in human serum.

    The value of nonfuel mineral production in 1991 was $111.6 million, a decrease of $16 million compared with the 1990 value. The decrease in 1991 was largely attributable to lower sales of construction sand and gravel and crushed stone, the State's two leading mineral commodities. Other mineral commodities produced included common clay, industrial sand, dimension stone, lime, and peat. Nationally, the State ranked 41st in the production of nonfuel minerals. It ranked fifth of 34 States that produced dimension stone.

    This paper discusses the surgical and medical problems affecting off-shore oil drilling workers in the south-eastern Atlantic coastline of the Nigerian territorial waters; about 50-60 kilometers from land. There were a total of 1300 attendances at the off-shore clinic within 12 months, ie 3.6 daily for a workforce of 110, were successfully managed by 2 well-trained industrial staff nurses who were supervised by an experienced base doctor on-shore. Although, most of the patients were treated for minor medical and surgical conditions such as headaches, malaria, cuts and bruises, a few acute emergencies arose which had to be taken on-shore by helicopters, for subsequent management. Four accidental deaths occurred during the period, one of them was clearly preventable but there were no major disasters. This demonstrated the effectiveness and significant role which well-trained nurses can play in industrial health.

    The fluxes of carbon, nitrogen and phosphorus through an off-shore long-line Mytilus galloprovincialis farm during a typical rearing cycle were estimated by combining a simple population dynamic model, based on a new individual model, and a set of field data, concerning the composition of the seston, as well as that of mussel meat and faeces. The individual model, based on an energy budget, was validated against a set of original field data, which were purposely collected from July 2006 to May 2007 in the North-Western Adriatic Sea (Italy) and was further tested using historical data. The model was upscaled to the population level by means of a set of Monte Carlo simulations, which were used for estimating the size structure of the population. The daily fluxes of C, N and P associated with mussel filtration, excretion and faeces and pseudo-faeces production were integrated over the 10-month-long rearing cycle and compared with the total amount of C, N and P removed by harvesting. The results indicate that the individual model compares well with an existing literature model and provides reliable estimations of the growth of mussel specimen over a range of trophic conditions which are typical of the Northern Adriatic Sea coastal area. The results of the budget calculation indicate that, even though the harvest represents a net removal of phosphorus and nitrogen from the ecosystem, the mussel farm increases the retention time of both nutrients in the coastal area, via the deposition of faeces and pseudo-faeces on the sea-bed. In fact, the amount of nitrogen associated with deposition is approximately twice the harvested one and the amount of phosphorus is approximately five times higher. These findings are in qualitative agreement with the results of literature budget and model calculations carried out in a temperate coastal embayment. This agreement suggests that the proper assessment of the overall effect of long-line mussel farming on both the benthic and pelagic

    Amphibious forces are the enabling force of choice to globally project rapid and sustainable combat power in the littoral. Whether delivering supplies and equipment for military operations or for humanitarian or disaster relief, the air cushioned landing craft (LCAC) is the primary surface ship-to-shore movement craft. The time needed to transfer the forces ashore may be critical to operational success and is an important planning consideration. Many factors complicate accurate prediction of this time. Even so, various commanders must use the best available information, given mission priorities and resource and capability limitations, to make numerous tradeoff decisions in planning and executing the movement of forces. A simulation toolbox, the simulated mobility modeling and analysis toolbox (SMMAT), is introduced, and a robust LCAC ship-to-shore simulation model is developed as an extension to SMMAT. This model provides the commander a prediction and tradeoff analysis tool for planning and executing the projection of power ashore.

    The study presents the statistical analysis of ozone sonde data obtained at Sodankyla (67.4 deg N, 26.6 deg E) from the beginning of the sounding program on March 1988 to the end of December 1991. The Sodankyla sounding data offers the longest continuous record of the ozone vertical distribution in the European Arctic. In this paper, we present the average ozone partial pressures within each 1 km column obtained for different seasons during the almost four year long period. We believe that the data represented here are useful as an interim reference ozone atmosphere, especially considering the fact that northern Scandinavia has become a popular campaign site for the big international ozone experiments.

  10. Temporal trends in vascular trauma in Ontario, 1991-2009: a population-based study

    Background: Vascular injuries add substantial complexity to trauma care, yet Canadian epidemiologic data on such injuries are not readily available. We conducted a retrospective cross-sectional study to examine temporal trends in the rate of hospital admissions for vascular injuries from 1991 to 2009 in Ontario. Methods: Individuals of any age admitted to hospital because of vascular trauma in Ontario were included. Details of vascular injury and patient demographic characteristics were recorded, hospital admission rates estimated and analyses stratified by sex, age, mechanism of injury, economic status and geographic location. Time-series analysis was used to examine trends in hospital admission rates. Results: Of the 8252 hospital admissions for vascular trauma, 4287 (52.0%) involved injuries to the upper limb and 1819 (22.0%) were due to transport-related causes. Overall, the annual rate declined significantly over time, from 3.3 per 100 000 in 1991 to 2.7 per 100 000 in 2009 (p < 0.01). The subgroups with the highest rates were young men, patients with a low economic status and those living in a rural location. Declines occurred in both sexes and in all age groups except those 65 years and older. The rates of vascular injury to the neck, thorax, upper limbs and lower limbs declined over time, but not the rate of abdominal vascular injury. Although the rate of non-transport-related vascular injuries declined, the rate of transport-related vascular injuries did not change significantly over time. Decreases in annual rates occurred in both low- and high-economic status groups and in urban populations but not in rural populations. Interpretation: Overall, the annual rate of hospital admissions for vascular trauma declined significantly in Ontario over the study period. Our findings have important implications for public health and the development of injury-prevention strategies, particularly for population subgroups at high risk of vascular injury. PMID

    2009-09-01

    Ecological services are defined as the conditions and processes through which natural ecosystems and the species that comprise them, sustain and fulfill human life, or the goods and services provided by ecosystem which contribute to human welfare, both directly and indirectly. Ecological service value has been a hot topic in ecological economic research. Beijing, the capital of China, covers an area of more than 16,410 square kilometers and has a population of 14.93 million people. It's also a fast-growing city with rapid urbanization, which may significantly impact ecological services and functions. Such effects are difficult to quantify and are seldom taken into account in the policy making process. So this article tried a technical process for calculating the ecological service value based on remote sensing. Then the article estimated variations in ecological services value in response to land use changes in Beijing from 1990 to 2006, and provided useful information and advice to policy-making for sustainable development of ecological environment.

So this article tried a technical process for calculating the ecological service value based on remote sensing. Then the article estimated variations in ecological services value in response to land use changes in Beijing from 1990 to 2006, and provided useful information and advice to policy-making for sustainable development of ecological environment.

    A combined analysis merges 17,000 Deep Space Network (DSN) Very Long Baseline Interferometric (VLBI) observations with 303,000 observations from the Crustal Dynamics Project (CDP) and the International Radio Interferometric Surveying (IRIS) project. Observations from the Radio Reference Frame Development (RRFD) and Time and Earth Motion Precision Observations (TEMPO) programs through late 1990 form the DSN VLBI data set. The combined analysis yields angular coordinates of extragalactic radio sources with a precision of a few nanoradians, as compared with 5 to 10 nrad precision for coordinates derived in the past solely from DSN data. The improvement in the combined analysis is due to the new Mark III DSN data, as well as to increased statistical strength from the large volume of observations from non-DSN experiments. Such a unified analysis is made possible by recent improvements in parameter estimation software efficiency. The terrestrial reference frame is based on joint VLBI experiments using both DSN and CDP antennas, and on specifying the coordinates of VLBI antennas in a proper geocentric coordinate system by means of Global Positioning System (GPS) collocation of VLBI, LLR, and SLR (Laser Ranging) sites.

    Ewing's sarcoma family of tumors (ESFTs) are rare bone and soft tissue tumors characterized by specific genetic alterations. Our aim was to carry out a nationwide analysis of ESFT, to survey the treatments used and to report the five-year disease specific and event-free survival rates (EFS and DSS). The study data was gathered from the Finnish National Cancer Registry and all five University Hospitals and consisted of 76 bone and soft tissue ESFT patients diagnosed during 1990-2009. Their medical records were reviewed and data on their disease, treatments, complications and outcome were analyzed. The five-year EFS and DSS of patients with localized disease at diagnosis (n = 57) were 70% and 60%, respectively. Factors contributing to DSS and EFS were the axial vs. peripheral site of primary tumor and adequate surgical resection of the primary tumor. DSS was also affected by patient's age at diagnosis and the treatment employed. The five-year DSS of patients with metastatic disease at diagnosis (n = 19) was 33% and both preoperative and high dose chemotherapy were associated with improved survival. Population-based studies including both bone and soft tissue ESFTs are few. In this nationwide, population-based study on Finnish bone and soft tissue ESFT patients, we find their treatment successful and results comparable to those previously published. Absence of metastases, young age at diagnosis and a peripheral primary tumor site were associated with a better prognosis. It seems that surgical resection of the primary tumor should be performed whenever adequate resection margins can be achieved. The role of high dose chemotherapy merits further studies in this setting.

Treatment integrity data were more likely to be included in studies that used teachers, multiple treatment agents, or both. Although there was a substantial increase in reporting operational definitions of independent variables, results suggest that there was only a modest improvement in reported integrity over the past 30 years of JABA studies. Recommendations for research and practice are discussed.

    The BEATRIX-2 experiment is an International Energy Agency (IEA) sponsored collaborative experiment between Japan, Canada, and the United States. The purpose of the experiment is to evaluate the performance of ceramic solid breeder materials in a fast neutron environment. To do this, an in-situ tritium recovery experiment is being conducted in the Fast Flux Test Facility (FFTF), located on the Hanford site near Richland, Washington, and operated by Westinghouse Hanford Company (WHC). The Pacific Northwest Laboratory (PNL), Richland, Washington, together with the Japan Atomic Energy Research Institute (JAERI) and Atomic Energy of Canada Limited (AECL) are responsible for conducting the experiment. This work is divided into two phases: Phase 1 was irradiated from January 1990 until March 1991 in Cycle 11 of FFTF, while Phase 2 will be irradiated in Cycle 12, which began in June 1991 and is scheduled to continue until approximately October of 1991 for 300 effective full power days (EFPD).

    2000-01-01

    Smoking prevalence rates in Switzerland in the 1990s++ have been estimated from Perma data, which have been available quarterly since 1991, as well as from the data of the first and second Swiss Health Surveys, conducted in 1992/93 and 1997. Both sources--each providing data on more than 10,000 respondents--have been large-scale surveys that have used different but complementary survey designs. The probabilistic sampling design of the Health Surveys assures representative findings; the Perma data, although obtained through a non-probabilistic sampling design, permits trend analysis as Perma uses multiple measurement points and therefore time-series methodology can be applied. Both Perma and the Health Surveys yielded approximately the same prevalence of 37% male smokers in 1992/93 and 39% in 1997. For females Perma gave 4% higher prevalence rates than the Health Surveys (Surveys 1992/93: 24%; 1997: 31%). For both sexes the increase in total smoking prevalence was accounted for mainly by adolescents and young adults. Whereas the Surveys showed an increase from 29% to 41% (18% to 39%) in males (females) aged 15 to 19 years, the corresponding increase derived from Perma was 50% less. Except for this youngest age-group, differences between the methods remained within standard statistical norms. There is no doubt, however, that smoking in adolescents increased between 1992/93 and 1997.

    1995-12-01

    A first-hand account is given of the epidemic of typhoid in the Goroka area as it evolved from 1984 to 1990. The monthly admissions for typhoid to Goroka Base Hospital showed a peak in 1988. The sex and age distribution showed a predominance of young adults. The overall case fatality rate of hospitalized patients was of the order of 10-15%; in a carefully documented group of 374 patients 27% were assessed as having severe typhoid and this subgroup had a case fatality rate of 44%. The clinical features were studied in 516 patients. The high mortality appeared to result from septic shock; ileal perforation was found in only 1.3% of patients. A skin lesion equivalent to but significantly different from the classic rose spot was found in 30% of patients. The typhoid facies was commonly encountered in patients with well-established typhoid. Cerebellar tremor and hearing loss were frequent diagnostic findings. Blood and bone marrow cultures were used to confirm the diagnosis; bone marrow culture proved practicable but gave little increased yield over blood culture. A clinical algorithm to help distinguish typhoid and malaria was developed, principally for use in health centres in the highlands. The mainstay of treatment was chloramphenicol and very few problems were encountered with its use in inpatients. Bacteriological resistance to chloramphenicol did not develop over the study period. Other drugs, such as fluorinated quinolones, may be more effective when all aspects are considered, despite higher cost, but this remains to be investigated. Hydrocortisone in patients with severe disease was evaluated and shown to be ineffective but whether high-dose dexamethasone would reduce the mortality from typhoid in patients in Papua New Guinea still remains an unanswered question.

    Faith-based organizations (FBOs) have been active in the health sector for decades. Recently, the role of FBOs in global health has been of increased interest. However, little is known about the magnitude and trends in development assistance for health (DAH) channeled through these organizations. Data were collected from the 21 most recent editions of the Report of Voluntary Agencies. These reports provide information on the revenue and expenditure of organizations. Project-level data were also collected and reviewed from the Bill & Melinda Gates Foundation and the Global Fund to Fight AIDS, Tuberculosis and Malaria. More than 1,900 non-governmental organizations received funds from at least one of these three organizations. Background information on these organizations was examined by two independent reviewers to identify the amount of funding channeled through FBOs. In 2013, total spending by the FBOs identified in the VolAg amounted to US$1.53 billion. In 1990, FB0s spent 34.1% of total DAH provided by private voluntary organizations reported in the VolAg. In 2013, FBOs expended 31.0%. Funds provided by the Global Fund to FBOs have grown since 2002, amounting to $80.9 million in 2011, or 16.7% of the Global Fund's contributions to NGOs. In 2011, the Gates Foundation's contributions to FBOs amounted to $7.1 million, or 1.1% of the total provided to NGOs. Development assistance partners exhibit a range of preferences with respect to the amount of funds provided to FBOs. Overall, estimates show that FBOS have maintained a substantial and consistent share over time, in line with overall spending in global health on NGOs. These estimates provide the foundation for further research on the spending trends and effectiveness of FBOs in global health.

    Ozone trends for 1979-1991, determined from Dobson spectrophotometer observations made at eight stations in the United States, are augmented with trend data from four foreign cooperative stations operated by NOAA/CMDL. Results are based on provisional data archived routinely throughout the years at the World Ozone Data Center in Toronto, Canada, with calibration corrections applied to some of the data. Trends through 1990 exhibit values of minus 0.3 percent to minus 0.5 percent yr(exp -1) at mid-to-high latitudes in the northern hemisphere. With the addition of 1991 data, however, the trends become less negative, indicating that ozone increased in many parts of the world during 1991. Stations located within the plus or minus 20 deg N-S latitude band exhibit no ozone trends. Early 1992 data show decreased ozone values at some of the stations. At South Pole, Antarctica, October ozone values have remained low during the past 3 years.

  20. Spatio-temporal development of sinkholes on the eastern shore of the Dead Sea

    The ongoing, largely anthropogenically-forced decline of the Dead Sea is associated with the most prolific development of sinkholes worldwide. The fall in hydrological base level since the 1960s is thought to enable relatively fresh ground waters to dissolve underground salt deposits that were previously in equilibrium with hypersaline Dead Sea brine. Sinkhole development in response to this dissolution began in the 1980s and is still ongoing; it represents a significant geohazard in the Dead Sea region. We present new research undertaken within the Dead Sea Research Venue (DESERVE) on the spatio-temporal evolution of the main sinkhole-affected site on the Eastern shore of the Dead Sea, at Ghor Al-Haditha in Jordan. Our data set includes optical satellite imagery, aerial survey photographs and drone-based photogrammetric surveys with high spatial (< 1 m2 - 0.05 m per pixel) and temporal (decadal from 1970-2010, annual from 2004-2016) resolution. These enable new quantitative insights into this, the largest of all the Dead Sea sinkhole sites. Our analysis shows that there are now over 800 sinkholes at Ghor al-Haditha. Sinkholes initiated as spatially distinct clusters in the late 1980's to early 1990s. While some clusters have since become inactive, most have expanded and merged with time. New clusters have also developed, mainly in the more recently exposed north of the area. With the retreat of the Dead Sea, the roughly coastline-parallel zone of sinkhole formation has expanded unevenly but systematically seawards. Such a seaward migration of sinkhole formation is predicted from hydrogeological theory, but as yet not consistently observed elsewhere at the Dead Sea. The rate of sinkhole formation at Ghor Haditha accelerated markedly during the late 2000s to a peak of about 100 per year in 2009. Similar accelerations are observed on the western shore, but differ in timing. The rate of sinkhole formation on the Eastern shore has since declined to about 50 per year

    The effects of climate change on the near shore coastal environment including ocean acidification, accelerated erosion, destruction of coral reefs, and damage to marine habitat have highlighted the need for improved equipment to study, monitor, and evaluate these changes [1]. This is especially true where areas of study are remote, large, or beyond depths easily accessible to divers. To this end, we have developed three examples of low cost and easily deployable real-time ocean observation platforms. We followed a scalable design approach adding complexity and capability as familiarity and experience were gained with system components saving both time and money by reducing design mistakes. The purpose of this paper is to provide information for the researcher, technician, or engineer who finds themselves in need of creating or acquiring similar platforms.

    The Ocean Networks Canada (ONC) Observatory, comprised of VENUS and NEPTUNE Canada (NC) cabled networks, supports transformative coastal to deep ocean research and enables real-time interactive experiments. Engaging students, educators and the public is critical to increasing the global awareness of our integral relationship with the ocean. One way to accomplish this is to encourage educators to incorporate marine science concepts into their lesson plans. ONC's new initiative, Ship2Shore Marine Educators (S2SME), enables educators to learn first hand about marine science and technology by going to sea on a maintenance/research cruise. While at sea Marine Educators (ME) participate in technology deployments, assist with water and core sampling, write daily blogs, produce short video updates, develop learning resources and conduct presentations to students on shore via video conferencing. MEs participating in the last NC cruise -"Wiring the Abyss 2012" - were fascinated with being a part of science in the real world. They had an experience of a lifetime and anticipate incorporating what they have learned into their lessons during the upcoming semester. Outreach between the MEs and ONC communication staff aboard the ship resulted in nearly 7,000 unique visitors to the "Wiring the Abyss 2012'' cruise website. Live ROPOS video feeds (~ 9,000 views), highlight videos (436 views/day), daily blogs (~1200 views) and stunning images (~391 views/day) were among the top rated pages. Visitors from 10 countries tuned in to "Wiring the Abyss 2012" and experienced the Pacific's deep sea! One of the best experiences for the MEs was connecting with students and teachers on shore via video conferencing. Roughly 300 students in BC and USA received a live connection from approximately 200km off the west coast. Students were most fascinated by a demo involving compressed Styrofoam cups, showing the intensity of pressure at the bottom of the sea. Successes: A positive working

    We have prepared a series of new carbohydrate-based materials based on the use of carbohydrates as a template for the introduction of functionality to polymeric materials with complete regio- and stereochemical control. The synthesis of these new materials by the use of chemical and enzymatic methods allows for the rational design of new materials based on the properties of the monomeric subunit. These materials have potential applications that range from their use in enhanced oil recovery to biodegradable plastics to biological applications including targeted drug delivery and enzyme stabilization.

    During the 1991 Persian Gulf War, over 700 oil wells in Kuwait were set ablaze by the withdrawing Iraqi army with the apparent intent of hindering satellite reconnaissance and intelligence gathering activities by the coalition of forces repelling Iraq from occupied Kuwait. The oil fires that burned for an estimated 10 months, created a huge smoke plume whose spatial extent went at times beyond the Persian Gulf region, mobilized across the Saharan Desert reaching as far west as the North Atlantic Ocean. The Nimbus-7 TOMS Total Ozone Mapping Spectrometer, in operation from October 1978 to May 1993, measured the near UV radiances that in the mid-1990's became the input in the calculation of the well know Absorbing Aerosol Index that represented a major breakthrough in satellite-based aerosol remote sensing. Thus, unknowingly to the world, the N7-TOMS sensor was collecting in 1991 an unprecedented daily record of what can be considered the worst environmental catastrophe affecting the atmosphere since the beginning of the era of space-based remote sensing in the 1970's. An overview of the temporal and spatial extent of the synoptic scale 1991 Gulf War smoke plume as seen by the Nimbus-7 TOMS Absorbing Aerosol Index will be presented.

    Under the current grant, the University of Tennessee Space Institute (UTSI) will carry out the bench scale evaluation and further development of the anion-exchange resin-based desulfurization concept to desulfurize alkali metal sulfates. This concept has been developed and patented by UTSI under US Patent No. 4,917,874. The developmental program proposed under this DOE grant includes screening of commercially available resins to select three candidate resins for further study. These three resins will undergo a series of experiments designed to test the resins` performance under different process conditions (including the use of spent MHD seed material). The best of these resins will be used in optimizing the regeneration step and in testing the effects of performance enhancers. The process schematic developed from the results will be used to estimate the related economics. During this reporting period, October 1, 1991 to September 30, 1992, analysis of batch mode screening experiments was completed to select three candidate resins for process variables study in the fixed-bed set-up. This setup was modified and the experiments were carded out to evaluate effects of major process variables. The analysis of fixed-bed experiments is going on and we have also started simple batch mode experiments to identify desirable conditions for resin regeneration step. We have also started simple process engineering type calculations to determine the trade-off between the solution concentration and the resulting evaporation/concentration load.

    The potential role of psychological stress in pancreatic cancer has rarely been investigated in epidemiologic studies. During 1991-2009, we conducted a nested case-control study based on Swedish national population and health registers to investigate whether severe psychological stress induced by the death of a child was associated with subsequent risk of pancreatic cancer. The study included 16,522 cases and 82,107 controls who were matched to the cases on sex and year of birth. Conditional logistic regression was used to estimate odds ratios and 95% confidence intervals. Overall, loss of a child was associated with an odds ratio of 1.09 for pancreatic cancer (95% confidence interval (CI): 1.02, 1.17). The risk elevation was mainly seen during the first 5 years after the loss (odds ratio (OR) = 1.27, 95% CI: 1.12, 1.45) and for loss of a child due to suicide (OR = 1.23, 95% CI: 1.03, 1.46). The association was statistically significant among women but not among men, and it appeared stronger for early-onset pancreatic cancer. Persons with a history of psychiatric illness had the greatest risk increase after child loss (OR = 1.43, 95% CI: 1.17, 1.76). Although other explanations are possible, our findings provide some evidence that psychological stress may be associated with pancreatic cancer.

    In addition to being effective, fast-acting, and well tolerated, artemisinin-based combination therapies (ACTs) are able to kill certain transmission stages of the malaria parasite. However, the population-level impacts of ACTs on reducing malaria transmission have been difficult to assess. In this study on the history of malaria control in Vietnam, we assemble annual reporting on malaria case counts, coverage with insecticide-treated nets (ITN) and indoor residual spraying (IRS), and drug purchases by provincial malaria control programs from 1991 to 2010 in Vietnam's 20 southern provinces. We observe a significant negative association between artemisinin use and malaria incidence, with a 10% absolute increase in the purchase proportion of artemisinin-containing regimens being associated with a 29.1% (95% confidence interval: 14.8-41.0%) reduction in slide-confirmed malaria incidence, after accounting for changes in urbanization, ITN/IRS coverage, and two indicators of health system capacity. One budget-related indicator of health system capacity was found to have a smaller association with malaria incidence, and no other significant factors were found. Our findings suggest that including an artemisinin component in malaria drug regimens was strongly associated with reduced malaria incidence in southern Vietnam, whereas changes in urbanization and coverage with ITN or IRS were not.

    The Magnetohydrodynamics (MHD) Integrated Topping Cycle (ITC) Project represents the culmination of the proof-of-concept (POC) development stage in the US Department of Energy (DOE) program to advance MHD technology to early commercial development stage utility power applications. The project is a joint effort, combining the skills of three topping cycle component developers: TRW, Avco/TDS, and Westinghouse. TRW, the prime contractor and system integrator, is responsible for the 50 thermal megawatt (50 MW{sub t}) slagging coal combustion subsystem. Avco/TDS is responsible for the MHD channel subsystem (nozzle, channel, diffuser, and power conditioning circuits), and Westinghouse is responsible for the current consolidation subsystem. The ITC Project will advance the state-of-the-art in MHD power systems with the design, construction, and integrated testing of 50 MW{sub t} power train components which are prototypical of the equipment that will be used in an early commercial scale MHD utility retrofit. Long duration testing of the integrated power train at the Component Development and Integration Facility (CDIF) in Butte, Montana will be performed, so that by the early 1990`s, an engineering data base on the reliability, availability, maintainability and performance of the system will be available to allow scaleup of the prototypical designs to the next development level. This Sixteenth Quarterly Technical Progress Report covers the period May 1, 1991 to July 31, 1991.

    This report is a summary and a guide to core-based stress measurements. It covers anelastic strain recovery, circumferential velocity anistropy, differential strain curve analysis, differential wave velocity analysis, petrographic examination of microcracks, overcoring of archieved core, measurements of the Kaiser effect, strength anisotropy tests, and analysis of coring-induced fractures. The report begins with a discussion of the stored energy within rocks, its release during coring, and the subsequent formation of relaxation microcracks. The interogation or monitoring of these microcracks form the basis for most of the core-based techniques (except for the coring induced fractures). Problems that can arise due to coring or fabric are also presented, Coring induced fractures are discussed in some detail, with the emphasis placed on petal (and petal-centerline) fractures and scribe-knife fractures. For each technique, a short description of the physics and the analysis procedures is given. In addition, several example applications have also been selected (where available) to illustrate pertinent effects. This report is intended to be a guide to the proper application and diagnosis of core-based stress measurement procedures.

    The goal of this study was to assess the susceptibility of the sub-population of over 500,000 immigrants from the former USSR who came to Israel during 1989-94 to HAV infection, and to provide military physicians with estimates of the prevalence of HBV and HCV carriage in this sub-population. 987 males aged 17-49 and 195 females aged 17-19, reporting to military recruitment offices between December 1991 and March 1992 were tested. Anti-HAV, anti-HBV antibodies and hepatitis B surface antigen (HBsAg) were detected by using standard enzyme immunoassay (EIA) tests, and anti-HCV antibodies by a second-generation EIA and confirmed by a third-generation INNO-LIA test. It was found that in the 17-19-year age-group the prevalence of anti-HAV antibodies was 37%, anti-HBV was 12.8%, HBsAg was 3.0% and anti-HCV 1.3%. All markers were higher among males. The prevalence of anti-HAV and anti-HBs antibodies increased with age among males. That of HBsAg and anti-HCV antibodies increased with age overall. In the multiple logistic regression analysis, HAV and HBV seropositivity were significantly associated with the mother's education and republic of origin. It was concluded that the prevalence of anti-HAV antibodies is similar to that among the local population, which should not be considered at a higher risk of infection during military service. On the other hand, the higher prevalence of HBsAg and anti-HCV antibodies in this sub-population should heighten the awareness of the possibility of chronic liver pathology.

    During 1990, about 1,460 million gallons per day (Mgal/d) of freshwater was withdrawn from surface- water and ground-water sources in Maryland. Total freshwater withdrawals increased during 1991 to about 1,500 Mgal/d. Saline surface-water withdrawals for cooling condensors increased from about 4,550 Mgal/d during 1990 to 5,760 Mgal/d during 1991. During 1990-91, most freshwater withdrawals (about 1,220 Mgal/d during 1990 and 1,250 Mgal/d during 1991) were from surface-water sources. More than 70 percent of the fresh surface water was withdrawn and used in the Potomac drainage basin. Most ground water (about 170 Mgal/d in 1990 and 184 Mgal/d in 1991) was withdrawn and used in the Upper Chesapeake drainage basin. The Potomac Group aquifers provided most of the ground water (about 64 Mgal/d during 1990 and 68 Mgal/d during 1991 or about 27 percent each year). Ten water-use categories represent the major demands on the surface-water and ground-water resources of the State: Public supply, domestic, commercial, industrial, mining, thermoelectric power, hydroelectric power, livestock, irrigation, and aquaculture. Largest withdrawals were for public supply (798 Mgal/d during 1990 and 826 Mgal/d during 1991), and the water was used by residences, commercial establishments, and industries. Baltimore City received the largest public-supply deliveries (totaling about 135 Mgal/d during 1990 and 127 Mgal/d during 1991). Freshwater withdrawals for self-supplied domestic use, aquaculture, and irrigation increased during the period, whereas withdrawals for commercial, industrial, thermo- electric power, and mining uses decreased.

    This paper reports that low crude oil prices and economic tough times in industrial countries cause a lean 1991 for members of the Organization of Petroleum Exporting Countries. OPEC's 1991 annual report the member countries reported an overall loss of $12 billion in 1991 on oil revenues that fell 16.2%. Iraq and Kuwait were not included because of their unusual circumstances in the wake of the Persian Gulf war. Reduced oil revenues reflected a slide to $18.66/bbl in 1991 from $22.26/bbl in 1990 for the average price of OPEC basket crudes. As of last June 5 OPEC's basket crude price has averaged only $17.42/bbl this year, OPEC News Agency (Opecna) reported. First quarter 1992 prices averaged $16.77/bbl, compared wit $19.31/bbl in fourth quarter 1991. The average price jumped 52 cent/bbl the first week in June this year to $19.93/bbl, bouyed by Saudi Arabia's move at the end of May to shift its policy from price moderation to one in favor of higher prices, Opecna the. OPEC members increased production 1% in 1991 to an average 23.28 million b/d in spite of negligible production from Iraq and Kuwait and reduced production from Qatar.

    This study refers to population based data and investigates the development of the mode of delivery associated with infertility treatment over the last 23 years. All 1 202,557 deliveries in Hesse, Germany, between 1990 and 2012 were assessed. 2.2% of the study population, 26,761, had a delivery subsequent to infertility treatment based on the Hessian Perinatal Registry (HEPE). An evaluation in this subgroup was performed investigating the associations between the mode of delivery and the gestational week and the mother's age. A continuous and significant (p<0.01) increase of cesarean section (CS) rates subsequent to infertility treatment (1990: 41,3%; 2012: 55,9%) as well as a conversely also significant (p<0.01) reduction of vaginal operative and spontaneous deliveries associated with infertility treatment between 1990 and 2012 was found. Furthermore, the preterm delivery rate and the proportion of deliveries of parturients older than 35 years of age in association with infertility treatment raised over the last years. Rates of full-term deliveries and deliveries of women younger than 35 years remained stable during the observation period. The rate of cesarean section is continuously rising over the last 23 years with regard to parturients subsequent to infertility treatment. The CS rate is significantly higher compared to women with a spontaneous pregnancy and in comparison to the data from 20 years ago. Most recently, the number of CS (51,2%) exceeded the number of vaginal deliveries (48,8%) in Hesse subsequent to infertility treatment for the first time. © Georg Thieme Verlag KG Stuttgart · New York.

    The value of nonfuel minerals produced in North Carolina decreased 6.2% from that of 1990. The value dropped from $589.7 million in 1990 to $552.9 million in 1991, largely as a result of the recession that has impacted the Nation in recent years. Decreases in the sales of the State's leading mineral commodity, crushed stone, as well as clays, feldspar, gemstones, scrap mica, olivine, construction sand and gravel, and pyrophyllite, more than offset small to moderate increases in the sales of lithium minerals, peat, phosphate rock, and industrial sand and gravel.

    The Optical Plume Anomaly Detection Program, an experimental study in the attempt to create a rocket engine health monitor based on detection and possible quantification of anomalous atomic and molecular species in the exhaust plume, has been in existence for several years. The instruments developed to monitor the exhaust plumes are presented. Two optical instruments are employed: the polychromator and the spectrometer. The polychromator is a 16 channel spectroradiometer having independent channels individually adjustable for center wavelength and pass bandwidth. Those values may be mechanically reset, with the aid of certain lab equipment. The spectrometer is a multichannel spectral analyzer having two 2048 element linear photodiode arrays at the exit plane of the dispersing instrument, which, like the 16 channel device, is a 1/2 meter grating spectrograph. These instruments are equipped with ultraviolet grade multifiber optical input cables, allowing the instruments to be placed in a benign environment. Telescopes mounted on the test stand observe the plume keeping the shock structure in view. The data acquisition and control system consist of four 80386-33 MHz computers: two at the test stand for instrument control and data preconditioning, and two in the test support building providing data archiving, display, and system control. Further descriptions of the instrumentation are provided.

  13. Change in Beaufort Sea Ice in the 1990s: A Perspective Based on Thickness

    Melling, H.; Riedel, D. A.

    2004-12-01

    A 12-year series of ice-draft measurements by sonar in the eastern Beaufort Sea provides opportunity to examine the impact of the warm 1990s in this area. The results are perhaps surprisingly. The average thickness of ice has changed little. The average ice coverage has changed little, although the coverage by old ice has increased slightly. The year 1998 stands out clearly as an anomaly. There is a large variation in average ice draft throughout the year which is driven by seasonally varying ice drift as well as by the annual cycle of freezing and melting. Inter-annual variation in average ice draft is also large, forced primarily by the impact of changes in average wind on ice circulation. However, year-to-year variation in storminess also appears important, through its impact on the flaw lead and on ridging along the coastal margin. The negligible trend in the average draft of the predominately first-year pack of this area is consistent with data for coastal sea ice over a wide area across northern Eurasia and North America, which span a half century. The trend may also be consistent with recent change in the thickness of pack ice in the central Arctic Ocean, when first-year and multi-year ice are examined separately.

    The objectives of this study were to analyse the total socio-economic impact of RA in Sweden during the period 1990-2010 and to analyse possible changes in costs during this period. The period was deliberately chosen to cover 10 years before and 10 years after the introduction of biologic drugs. A prevalence-based cost-of-illness study was conducted based on data from national and regional registries. There was a decrease in the utilization of RA-related inpatient care as well as sick leave and disability pension during 1990-2010 in Sweden. Total costs for RA are presented in current prices as well as inflation-adjusted with the consumer price index (CPI) and a healthcare price index. The total fixed cost of RA was €454 million in 1990, adjusted to the price level of 2010 with the CPI. This cost increased to €600 million in 2010 and the increase was mainly due to the substantially increasing costs for pharmaceuticals. Of the total costs, drug costs increased from 3% to 33% between 1990 and 2010. Consequently the portion of total costs accounting for indirect costs for RA is lowered from 75% in 1990 to 58% in 2010. By inflation adjusting with the CPI, which is reasonable from a societal perspective, there was a 32% increase in the total fixed cost of RA between 1990 and 2010. This suggests that decreased hospitalization and indirect costs have not fallen enough to offset the increasing cost of drug treatment.

    Recent sustainability science research focuses on tradeoffs between human well-being and stress placed on the environment from fossil fuel consumption, a relationship known as the carbon intensity of well-being (CIWB). In this study we assess how the effect of economic development on consumption-based CIWB--a ratio of consumption-based carbon dioxide emissions to average life expectancy--changed from 1990 to 2008 for 69 nations throughout the world. We examine the effect of development on consumption-based CIWB for the overall sample as well as for smaller samples restricted to mostly high-income OECD nations, Non-OECD nations, and more nuanced regional samples of Non-OECD nations in Africa, Asia, and Latin America. We find that the effect of economic development on CIWB increased through time for the overall sample. However, analyses of the Non-OECD and OECD samples indicate that while the effect of development on CIWB increased from null to a moderate level for the Non-OECD nations, the effect of economic development was much larger, relatively stable through time, and more unsustainable for the OECD nations. Additional findings reveal important regional differences for Non-OECD nations. In the early 1990s, increased development led to a reduction in CIWB for Non-OECD nations in Africa, but in more recent years the relationship changed, becoming less sustainable. For the samples of Non-OECD nations in Asia and Latin America, we find that economic development increased consumption-based CIWB, and increasingly so throughout the 19 year period of study.

    Canada's forests play an important role in the global carbon (C) cycle because of their large and dynamic C stocks. Detailed monitoring of C exchange between forests and the atmosphere and improved understanding of the processes that affect the net ecosystem exchange of C are needed to improve our understanding of the terrestrial C budget. We estimated the C budget of Canada's 2.3 × 106 km2 managed forests from 1990 to 2008 using an empirical modelling approach driven by detailed forestry datasets. We estimated that average net primary production (NPP) during this period was 809 ± 5 Tg C yr−1 (352 g C m−2 yr−1) and net ecosystem production (NEP) was 71 ± 9 Tg C yr−1 (31 g C m−2 yr−1). Harvesting transferred 45 ± 4 Tg C yr−1 out of the ecosystem and 45 ± 4 Tg C yr−1 within the ecosystem (from living biomass to dead organic matter pools). Fires released 23 ± 16 Tg C yr−1 directly to the atmosphere, and fires, insects and other natural disturbances transferred 52 ± 41 Tg C yr−1 from biomass to dead organic matter pools, from where C will gradually be released through decomposition. Net biome production (NBP) was only 2 ± 20 Tg C yr−1 (1 g C m−2 yr−1); the low C sequestration ratio (NBP/NPP=0.3%) is attributed to the high average age of Canada's managed forests and the impact of natural disturbances. Although net losses of ecosystem C occurred during several years due to large fires and widespread bark beetle outbreak, Canada's managed forests were a sink for atmospheric CO2 in all years, with an uptake of 50 ± 18 Tg C yr−1 [net ecosystem exchange (NEE) of CO2=−22 g C m−2 yr−1].

  1. Survival of hatchery-reared lake trout stocked near shore and off shore in Lake Ontario

    Establishing a stock of mature, hatchery-reared fish is necessary to restore a self-sustaining population of lake trout Salvelinus namaycush in Lake Ontario. Stocking fish off shore rather than near shore to reduce predation on these fish by large lake trout or piscivorous birds may enhance survival of hatchery-reared fish and accelerate establishment of a population of adults. Results of an earlier study did not support routinely stocking fish off shore by helicopter in Lake Ontario, but stresses associated with helicopter stocking suggested another method of transporting fish off shore might enhance survival. I conducted this study to determine whether stocking lake trout off shore by barge would enhance first-year survival. Two lots of yearling lake trout were stocked at each of four locations in Lake Ontario in May 1992. One lot was stocked from shore, and an identical lot was transported by barge 3.4–10.4 km off shore of nearshore locations and stocked in water 46–52 m deep. Fish were recovered during trawl, gillnet, and creel surveys in 1992–1996. First-year survival of lake trout stocked off shore tended to be better than that of fish stocked near shore. Predation by double-crested cormorantsPhalacrocorax auritus likely affected survival of fish stocked near shore at two locations, 7 and 37 km, respectively, from a nesting colony of 5,443 pairs of double-crested cormorants. Predation by large lake trout remains a viable hypothesis, which explains, at least partially, lower survival of lake trout stocked near shore at two other locations. Stocking lake trout off shore of traditional nearshore stocking sites likely will enhance first-year survival of hatchery-reared fish and promote accumulation of an adult population, especially for those occassions where nearshore stocking locations are near nesting colonies of double-crested cormorants.

    This paper reports that for the sixth consecutive year, Oman should retain its title as the biggest driller in the Middle East in 1991. An accelerated program in 1990 pushed production to an all-time record 700,000 bpd late in the year. Although not a member of Opec, Oman has cooperated with the group in restraining output as needed to support oil prices. Petroleum Development Oman (PDO), a partnership of the government (60%), Royal Dutch Shell (34%), Total (4%) and Partex (2%), remains by far the biggest producer. This year, PDO will begin work on its $500-million effort to boost production from its Lekhwair field from a current 24,000 bpd to 110,000 bpd by 1994. Last year, PDO also drilled 15 horizontal wells, most of which were successful in increasing per well production compared to conventional vertical holes. The horizontal program has been continued this year with two rings.

    1993-04-01

    Energy consumption in California fell in 1991 for the first time in five years. The State`s economy was especially hard hit by a continuing national recession. The construction industry for the second year experienced a dramatic downturn. Energy use in the industrial sector showed a modest increase, but consumption in other end-use categories declined. The decrease in energy used in transportation can be traced to a substantial fall in the sales of both highway diesel fuels and vessel bunkering fuels at California ports, the latter reflecting a mid-year increase in taxes. Gasoline sales by contrast increased as did the number of miles traveled and the number of automobiles in the State. Production in California`s oil and gas fields was at 1990 levels thus arresting a steady decline in output. Due to enlarged steam flooding operations, production at several fields reached record levels. Also countering the decline in many of California fields was new production from the Port Arguello offshore field. California natural gas production, despite a modest 1991 increase, will not fill the use within the State. Petroleum comprised more than half of the State`s energy supply principally for transportation. Natural gas use showed a small increase. Oil products play virtually no role in electrical production. The largest single source of electricity to the State is imports from the Pacific Northwest and from coal-fired plants in the Southwest. Combined contributions to transmitted electricity from renewable and alternate sources declined as hydropower was constrained by a prolonged drought and as geothermal power from the largest and oldest field at The Geysers fell. Windpower grew slightly; however solar power remained at 1990 levels and made no substantial contribution to total power generation.

    This report describes research into polycrystalline CdTe solar cells grown by metal-organic chemical vapor deposition. Efficiencies of {approximately}10% were achieved using both p-i-n and p-n structures. A pre-heat treatment of CdS/SnO{sub 2}/glass substrates at 450{degrees}C in hydrogen atmosphere prior to the CdTe growth was found to be essential for high performance because this heat treatment reduces oxygen-related defects from the CdS surface. However, this treatment also resulted in a Cd-deficient CdS surface, which may in part limit the CdTe cell efficiency to 10% due to Cd vacancy-related interface defects. Preliminary model calculations suggest that removing these states can increase the cell efficiency from 10% to 13.5%. Photon absorption in the CdS film also limits the cell performance, and eliminating this loss mechanism can result in CdTe efficiencies in excess of 18%. Polycrystalline, 1.7-e, CdZnTe films were also grown for tandem-cell applications. CdZnTe/CdS cells processed using the standard CdTe cell fabrication procedure resulted in 4.4% efficiency, high series resistance, and a band-gap shift to 1.55 eV. The formation of Zn-O at and near the CdZnTe surface is the source of high contact resistance. A saturated dichromate each prior to contact deposition was found to solve the contact resistance problem. The CdCl{sub 2} treatment was identified as the cause of the observed band-gap shift due to the preferred formation of ZnCl{sub 2}. 59 refs.

    Carbon fluxes were estimated for 84 regions (54 lands + 30 oceans) over the globe during the period of 1990-2011. We used (1) the CCSR/NIES/FRCGC AGCM-based Chemistry Transport Model (ACTM), (2) atmospheric CO2 concentrations at 74 sites from GLOBALVIEW-CO2 (2013) data product, (3) Seasonally varying a presubtracted fluxes for atmosphere-ocean exchange (Takahashi et al., 2009), (4) interannually varying a priori fossil fuel fluxes (incl. cement production) from CDIAC global totals and EDGAR4.2 spatial distributions, and (5) 3-hourly terrestrial biosphere fluxes are constructed from the annually balanced CASA and JRA-25 reanalysis meteorology (Y. Niwa, Pers. Comm., 2013). As a result of time-dependent inversions, mean total flux (excluding fossil fuel) for the period 1990-2011 is estimated to be -3.33 GtC/yr, where land (incl. biomass burning and land use change) and ocean absorb an average rate of -1.98 and -1.35 GtC/yr, respectively. The land uptake is mainly due to northern land (-1.57 GtC/yr), while the tropical and southern lands contribute -0.03 and -0.38 GtC/yr, respectively. It is also found that Boreal North America and Boreal Eurasia show negative trends in the estimated fluxes during the analysis period. The global ocean sink has no clear long-term trend in the period. Results with different inversion settings and for other regions will be discussed. Our analysis suggests that no known transport bias in ACTM forward simulation allow us to estimate CO2 fluxes at good accuracy at hemispheric and regional scale. Acknowledgements.

    The reporting of pain was compared for U.K. Persian Gulf War veterans, veterans from the Bosnian conflict, and personnel employed in the military at the time of the Persian Gulf War but not deployed (era comparison group). Pain manikins were used to assess the prevalence of the reporting of pain in different body sites and the prevalence of the reporting of widespread pain, in relation to comparison samples. Data from > 8,195 veterans were collected from a previously reported, cross-sectional, population-based, postal questionnaire survey. A greater proportion of Persian Gulf War veterans reported pain in the majority of the 25 areas of the body, compared with the Bosnia and era comparison groups. A greater proportion of Persian Gulf War veterans also fulfilled American College of Rheumatology criteria for widespread pain, compared with the Bosnia and era comparison groups (odds ratio, 1.82; 95% confidence interval, 1.51-2.20). Participants were much more likely to report pain in an opposite limb if pain was reported in the first limb (odds ratio, 36.9; 95% confidence interval, 31.7-43.0). Widespread pain was also more prevalent in the Persian Gulf War veteran sample compared to the comparison groups. Several years after the end of the Persian Gulf War, veterans still report pain. The mechanisms of this remain unclear. Implications for baseline monitoring of the health of military personnel are discussed.

    1992-06-01

    Minister Peng of the State Family Planning (FP) Commission of China's remarks are summarized. A major new achievement in 1991 was the meeting of population targets in FP. The birth rate for 1991 was 19.68/1000, which was lower than the 1991 target by .118%. The rate of natural increase was 12.98/1000, which was also lower. 1991 marks the lowest population increase in 6 years. Even though those 20-29 years and those at peak childbearing years increased over 1990, the rate of natural increase still declined by .1%. The decline is attributed to the strengthening of all Party leadership over FP; to more widespread publicity and education on FP and acceptance; more conscientious contraception, including permanent methods, and effective FP research; and strengthening of grassroots level FP. 1992 is the year of the 3rd baby boom peak since 1949. 318.9 million will be of childbearing age in 1992, which is an increase of 4.1 million; 13.25 million will be those at the peak age (23 years); 123.7 million will be fecund ages (20-29 years). Continued work is required in strengthening FP, in improving management of population and FP targets, in extensive and penetrating publicity on FP, on consistent and focused FP policy implementation, on increasing input for FP programs, and on pooling government and society's resources for administration of the population problem. Conscientious FP means responsibility and urgency in implementation, FP as a priority, and active FP effort. Earnest FP means using "down to earth" grassroots implementation which is painstaking and meticulous. Persistent FP means unremitting effort in a longterm struggle in controlling population growth. The quality of statistics needs to be improved as well as better criteria for assessment. Emphasis should be on the socioeconomic benefits of the FP program. The focus is still rural areas. The operating funds for FP have been increased to 2 yuan RMB per capita/year. Minorities should practice FP, and a conference

    Chemical engineers use mathematical simulators to design, model, optimize and refine various engineering plants/processes. This procedure requires the following steps: (1) preparation of an input data file according to the format required by the target simulator; (2) excecuting the simulation; and (3) analyzing the results of the simulation to determine if all ``specified goals`` are satisfied. If the goals are not met, the input data file must be modified and the simulation repeated. This multistep process is continued until satisfactory results are obtained. This research was undertaken to develop a knowledge based system, IPSE (Intelligent Process Simulation Environment), that can enhance the productivity of chemical engineers/modelers by serving as an intelligent assistant to perform a variety tasks related to process simulation. ASPEN, a widely used simulator by the US Department of Energy (DOE) at Morgantown Energy Technology Center (METC) was selected as the target process simulator in the project. IPSE, written in the C language, was developed using a number of knowledge-based programming paradigms: object-oriented knowledge representation that uses inheritance and methods, rulebased inferencing (includes processing and propagation of probabilistic information) and data-driven programming using demons. It was implemented using the knowledge based environment LASER. The relationship of IPSE with the user, ASPEN, LASER and the C language is shown in Figure 1.

    The oceans are the world's largest solar energy collector and storage system. Covering 71 percent of the earth's surface, the oceans collect and store this energy as waves, currents, and thermal and salinity gradients. The purpose of the US Department of Energy's (DOE) Ocean Energy Program is to develop techniques that harness ocean energy cost effectively and in ways that do not harm the environment. The program seeks to develop ocean energy technology to a point at which industry can accurately assess whether the applications of the technology are viable energy conversion alternatives, or supplements to current power-generating systems. In past studies, DOE identified ocean thermal energy conversion (OTEC), which uses the temperature difference between warm surface water and cold deep water, as the most promising of the ocean energy technologies. As a result, the Ocean Energy Program has concentrated research that advances OTEC technology. The program also monitored developments in wave energy, ocean current, and salinity gradient concepts.

    The Berkeley Compact Toroid Experiment (BCTX) device is a plasma device with a Marshall-gun generated, low aspect ratio toroidal plasma. The device is capable of producing spheromak-type discharges and may, with some modification, produce low-aspect ratio tokamak configurations. A unique aspect of this experimenal devie is its large lower hybrid (LH) heating system, which consists of two 450MHz klystron tubes generating 20 megawatts each into a brambilla-type launching structure. Successful operation with one klystron at virtually full power (18 MW) has been accomplished with 110 {mu}s pulse length. A second klystron is currently installed in its socket and magnet but has not been added to the RF drive system. This report describes current activities and accomplishments and describes the anticipated results of next year`s activity.

    This proposal focuses on research on three distinct areas of particle physics: (1) Nonperturbative QCD. I tend to continue work on analytic modelling of nonperturbative effects in the strong interactions. I have been investigating the theoretical connection between the nonrelativistic quark model and QCD. The primary motivation has been to understand the experimental observation of nonzero matrix elements involving current strange quarks in ordinary matter -- which in the quark model has no strange quark component. This has led to my present work on understanding constituent (quark model) quarks as collective excitations of QCD degrees of freedom. (2) Weak Scale Baryogenesis. A continuation of work on baryogenesis in the early universe from weak interactions. In particular, an investigation of baryogenesis occurring during the weak phase transition through anomalous baryon violating processes in the standard model of weak interactions. (3) Flavor and Compositeness. Further investigation of a new mechanism that I recently discovered for dynamical mass generation for fermions, which naturally leads to a family hierarchy structure. A discussion of recent past work is found in the next section, followed by an outline of the proposed research. A recent publication from each of these three areas is attached to this proposal.

    Based on the National Automotive Sampling System Crashworthiness Data System since the 1988–1992 model years, there has been a reduction in the MAIS 3+ injury rate and the Mean HARM for all crash modes. The largest improvement in vehicle safety has been in rollovers. There was an increase in the rollover injury rate in the 1993–1998 model year period, but a reduction since then. When comparing vehicles of the model year 1993 to 1998 with later model vehicles, the most profound difference was the reduction of rollover frequency for SUV’s – down more than 20% when compared to other crash modes. When considering only model years since 2002 the rollover frequency reduction was nearly 40%. A 26% reduction in the rate of moderate and serious injuries for all drivers in rollovers was observed for the model years later than 1998. The overall belt use rate for drivers of late model vehicles with HARM weighted injuries was 62% - up from 54% in earlier model vehicles. However, in rollover crashes, the same belt use rate lagged at 54%. PMID:23169134

    The data presented in this report are the result of Brine Sampling and Evaluation Program (BSEP) activities at the Waste Isolation Pilot Plan (WIPP) during 1991. These BSEP activities document and investigate the origins, hydraulic characteristics, extent, and composition of brine occurrences in the Permian Salado Formation and seepage of that brine into the excavations at the WIPP. When excavations began at the WIPP in 1982, small brine seepages (weeps) were observed on the walls. Brine studies began as part of the Site Validation Program and were formalized as a program in its own right in 1985. During nine years of observations (1982--1991), evidence has mounted that the amount of brine seeping into the WIPP excavations is limited, local, and only a small fraction of that required to produce hydrogen gas by corroding the metal in the waste drums and waste inventory. The data through 1990 is discussed in detail and summarized by Deal and others (1991). The data presented in this report describes progress made during the calendar year 1991 and focuses on four major areas: (1) quantification of the amount of brine seeping across vertical surfaces in the WIPP excavations (brine ``weeps); (2) monitoring of brine inflow, e.g., measuring brines recovered from holes drilled downward from the underground drifts (downholes), upward from the underground drifts (upholes), and from subhorizontal holes; (3) further characterization of brine geochemistry; and (4) preliminary quantification of the amount of brine that might be released by squeezing the underconsolidated clays present in the Salado Formation.

    Solar radiation measurements were made using sun photometers and pyranometers during 31 May-7 June 1991 at several places in Iran and during 12 June-17 September 1991 at a fixed place, Bushehr, Iran. In the first period the aerosol optical thickness had values about 0.4 at the wavelength of 0.5 m in the coastal area and about 0.2 in the plateau area. The Ångström's exponent, which is the slope of optical thickness spectrum, had values around 1 for large city areas and less than 0.5 for inland arid areas. Chemical analyses of sampled air indicate an effect of fossil fuel burning from local sources. Such optical and chemical characteristics of atmospheres suggest that soil-derived coarse particles contributed considerably to the atmospheric turbidity in arid areas, whereas an active generation of aerosols was dominant near large cities.Significant rises in atmospheric turbidity were observed in the earlier part of the second period at Bushehr about once a week with a duration of about one day, which may have been caused by smoke from oil-well fires in Kuwait. The aerosol optical thickness in these events had values of about 1.5, which is equivalent to a columnar aerosol volume of 4.4 × 104 cm3 cm2. The absorption index ranged from 0.005 to 0.02 with several peaks reaching 0.1 in the second period. These peaks can be attributed to prevailing smoke particles. In spite of the large variety of optical thicknesses and absorption indices, there existed stable power-law size distributions with an exponent about 3.7.

    2007-07-01

    The research was carried out to determine whether there are individual-level differences in the bicolor damselfish (Stegastes partitus) within the altered fish communities located on the north coast of Havana, Cuba. There was strong evidence of changes in some morphological and physiological characteristics associated with the impact of land-based pollution in the coastal zone. A combination of impaired recruitment due to habitat degradation with increased food supply due to eutrophication seems to be the best explanation for fishes being heavier and longer at polluted sites. The change in the proportion of color patterns and a very high number of atretic oocytes in the ovaries of fish caught near the mouth of the Almendares River strongly support the idea that not only is the pollution of river waters affecting the marine life in the coastal zone, but also that this pollution has greater effects than the pollution coming from the discharge of Havana Harbor.

    The February 8, 1990 earthquake at Bohol area is one of the few strong earthquakes that have affected central Philippines since the early 1900's. This M6.0 1990 Bohol event nonetheless wrought havoc to at least 16 municipalities, caused numerous casualties, injured about three hundred people, rendered several thousand homeless and evacuated from the coastal areas, and damaged at least P154 million worth of properties. The epicenter of this earthquake was initially placed onshore at 17km east of Tagbilaran City and was attributed to the movement along the Alicia Thrust Fault- a fault trending northeast-southwest. Noticeably, there was no surface rupture and the succeeding aftershocks clustered along a northeast-southwest trend off the eastern shore of Bohol island. In addition, the southeastern part of Bohol island experienced tsunami inundation particularly the municipalities of Jagna, Duero, Guindulman, Garcia Hernandez, and Valencia. In this study, several issues were resolved regarding this seismic event. First, the 1990 Bohol earthquake was generated along an offshore thrust fault based on the reviews of seismicity data from the NEIC. -Post-determined plots of the mainshock and aftershocks indicate offshore event with focal mechanism solutions that imply thrust fault activity. Intensity data likewise indicates that intense ground shaking was mainly felt in the southeastern part of the island. Second, recent field investigations undertaken clearly indicated a widespread tsunami inundation wherein the southeastern shorelines of Bohol likewise experienced a regional retreat in sea level several minutes after the strong ground shaking. Lastly, such tsunamigenic structure could somehow explain the anomalously large waves that impacted Camiguin island, an island more than 50km southeast of Bohol. A reconstruction of true tsunami heights and runup distances was also undertaken based from eyewitness accounts. Future works would involve relocation of aftershocks and

    Melt ponds form on Arctic sea ice during the melting season and their presence affects the heat and mass balances of the ice cover, mainly by decreasing the value of the surface albedo by up to 20%. We have developed a melt pond model suitable for forecasting the presence of melt ponds based on sea ice conditions. This model has been incorporated into the Los Alamos CICE sea ice model, the sea ice component of several IPCC climate models. Simulations for the period 1990 to 2012 are in good agreement with observed ice concentration. The maximum pond area occurs in the beginning of July with an Arctic mean of 25% (fraction of sea ice). The inter-annual variability is strong with the lowest maximum fraction of 15% in 1996 and the highest maximum fraction of 38% in 2011. In 2007, the melt pond area is exceptionally high in the early season (June). Spatial distributions show variation of pond fraction between 5% and 70%. The reasons for the inhomogeneity are analyzed with respect to driving factors: melt rate, sea ice topography, loss of melt water (e.g. due to leads and ridging).

    The report has been prepared under a Memorandum of Understanding between the Bureau of Mines, U.S. Department of the Interior, and the Montana Bureau of Mines and Geology for collecting information on all nonfuel minerals. Montana's 1991 nonfuel mineral production value was $590 million, an increase of 3% from that of 1990. Gains in the production value of portland cement, copper, and gold more than offset the decrease in values of molybdenum, platinum-group metals, silver, crushed stone, and zinc. Metallic minerals-copper, gold, iron ore, lead, molybdenum, platinum-group metals, silver, and zinc-accounted for more than 82% of Montana's total nonfuel mineral production value. The State ranked 17th nationally in value compared with 19th in 1990.

    There are many immigrants in the Swedish workforce, but knowledge of their general and work-related health is limited. The aim of this register-based study was to explore whether documented migrant residents in Sweden have a different health status regarding receipt of a disability pension, mortality and hospitalization for lung, heart, psychiatric, and musculoskeletal disorders compared with the native population, and if there were variations in relation to sex, geographical origin, position on the labor market, and time since first immigration. This study included migrants to Sweden since 1960 who were 28-47 years old in 1990, and included 243 860 individuals. The comparison group comprised a random sample of 859 653 native Swedes. These cohorts were followed from 1991 to 2008 in national registers. The immigrants were divided into four groups based on geographic origin. Hazard ratios for men and women from different geographic origins and with different employment status were analyzed separately for the six outcomes, with adjustment for age, education level, and income. The influence of length of residence in Sweden was analyzed separately. Nordic immigrants had increased risks for all investigated outcomes while most other groups had equal or lower risks for those outcomes than the Swedes. The lowest HRs were found in the EU 15+ group (from western Europe, North America, Australia and New Zealand). All groups, except Nordic immigrants, had lower risk of mortality, but all had higher risk of disability pension receipt compared with native Swedes. Unemployed non-Nordic men displayed equal or lower HRs for most outcomes, except disability pension receipt, compared with unemployed Swedish men. A longer time since first immigration improved the health status of men, while women showed opposite results. Employment status and length of residence are important factors for health. The contradictory results of low mortality and high disability pension risks need more

    During the last two decades light transmission (LT) data have been collected routinely in the Eastern Mediterranean Sea, within the framework of several research projects. A procedure was developed to obtain beam attenuation coefficient due to particles ( cp) at 660-670 nm adjusted for variations in mid-depth 'clear' water and instrumental drifts. Data from 3146 stations occupied between 1991 and 2001 were converted to a common format for the analysis of particulate matter (PM) temporal and spatial distribution patterns. The data were separated into 'wet' (December-May) and 'dry' (June-November) periods. The horizontal distribution of beam cp at various depths revealed clearly higher values in the surface nepheloid layer (SNL) in the vicinity of river mouths during the 'wet' period, whilst the increase was negligible during the 'dry' period. In contrast, the bottom nepheloid layer (BNL; 1-10 m above bottom) appeared to be turbid throughout the year, particularly on the continental shelves receiving riverine discharge. This feature is attributed to resuspension and advection of recently deposited bottom sediments due to waves and currents. However, the Eastern Mediterranean as a whole is impoverished in PM in the water column, particularly at depths >200 m. The behavior of surface-water cp revealed a strong relationship to mesoscale dynamic features. Cyclonic eddies, which upwell nutrient-rich waters toward the surface, favor primary production, which was identified as elevated beam cp values. Beam cp was correlated with PM concentration (PMC) and particulate organic carbon (POC) concentration obtained by bottle sampling. Although there were regional differences in the correlations, no significant seasonal variations were observed. Two generic equations were generated that can be used for a first-order estimate of PMC and POC from historical LT measurements conducted in the area, provided that data are handled according to the proposed methodology.

    In recent years, Salmonella enteritidis has become an increasingly important public health problem in Italy. In some parts of the country, the fraction of total human salmonella isolates accounted for by S. enteritidis has risen from 3-4% in the mid-1980s to more than 30% in 1990. Between 1990 and 1991, the number of reported S. enteritidis outbreaks increased more than sixfold. The 33 outbreaks reported in 1991 occurred in seven contiguous regions in northern and central Italy and were clustered in time between June and October; in the majority, products containing raw or undercooked shell eggs were implicated. Five of the egg-related outbreaks that occurred within a 30 kilometre radius over a 7-week period were investigated in detail. A phage type 1 strain containing a 38·9 MDa plasmid appeared responsible for three of the outbreaks, while in the remaining two a phage type 4 strain, also with a 38·9 MDa plasmid was isolated. Efforts are being made to enhance epidemiological surveillance and laboratory evaluation, and the use of pasteurized eggs has been recommended for high-risk populations. PMID:8472765

    Background In the past two decades, health inequality has persisted or increased in states with comprehensive welfare. Methods We conducted a national registry-based repeated cohort study with a 3-year follow-up between 1990 and 2007 in Sweden. Information on all-cause mortality in all working-age Swedish men and women aged between 30 and 64 years was collected. Data were subjected to temporal trend analysis using joinpoint regression to statistically confirm the trajectories observed. Results Among men, age-standardised mortality rate decreased by 38.3% from 234.9 to 145 (per 100 000 population) over the whole period in the highest income quintile, whereas the reduction was only 18.3% (from 774.5 to 632.5) in the lowest quintile. Among women, mortality decreased by 40% (from 187.4 to 112.5) in the highest income group, but increased by 12.1% (from 280.2 to 314.2) in the poorest income group. Joinpoint regression identified that the differences in age-standardised mortality between the highest and the lowest income quintiles decreased among men by 18.85 annually between 1990 and 1994 (p trend=0.02), whereas it increased later, with a 2.88 point increase per year (p trend <0.0001). Among women, it continuously increased by 9.26/year (p trend <0.0001). In relative terms, age-adjusted mortality rate ratios showed a continuous increase in both genders. Conclusions Income-based inequalities among working-age male and female Swedes have increased since the late 1990s, whereas in absolute terms the increase was less remarkable among men. Structural and behavioural factors explaining this trend, such as the economic recession in the early 1990s, should be studied further. PMID:25143429

    The Columbia River Basin Fish and Wildlife Program (Program) was developed by the Northwest Power Planning Council (Council) in accordance with Public Law 96-501, the Pacific Northwest Electric Power Planning and Conservation Act (Act). The purpose of the Program is to guide the Bonneville Power Administration (BPA) and other Federal agencies in carrying out their responsibilities to protect, mitigate, and enhance fish and wildlife of the Columbia River Basin. The Act explicitly gives BPA the authority and responsibility to use the BPA fund for these ends, to the extent that fish and wildlife are affected by the development and operation of hydroelectric generation in the Columbia River Basin. The Columbia River Basin Fish and Wildlife Program Annual Implementation Work Plan (AIWP) presents BPA's draft plans for implementing the Program during Fiscal Year (FY) 1991. The AIWP reflects the primary goals of the Council's Action Plan (Section 1400 of the Program): to provide a solid, timely, and focused basis for budgeting and planning. In addition, the AIWP provides a means to judge the progress and the success of Program implementation. The AIWP is based on the outline developed by the Policy Review Group (PRG) during Step 1 of the annual cycle of the Implementation Planning Process (IPP), which is described in Section III. This AIWP has been organized and written to meet the specific needs of Program Items 10.1-10.3. The AIWP includes schedules with key milestones for 1 and beyond, and addresses the Action Items assigned to BPA in Section 1400 of the 1987 Program and in subsequent amendments. All Program projects discussed in the AIWP are listed in Tables 1 and 2 according to their status as of September 1, 1990. Table 1 (pp. 3-14) lists completed, ongoing, and deferred projects. Table 2 (pp. 15-17) lists FY 1991 new-start projects. ''Ongoing'' status indicates that the project started in FY 1990 or before and that it is expected to continue through part or all of

    The purpose of the Hanford Environmental Dose Reconstruction (HEDR) Project is to estimate radiation doses from Hanford Site operations since 1944 to populations and individuals. The objectives of work in Fiscal Year (FY) 1991 are to analyze data and models used in Phase 1 and restructure the models to increase accuracy and reduce uncertainty in dose estimation capability. Databases will be expanded and efforts will begin to determine the appropriate scope (space, time, radionuclides, pathways and individuals/population groups) and accuracy (level of uncertainty in dose estimates) for the project. Project scope and accuracy requirements, once defined, can be translated into additional model and data requirements later in the project. Task plans for FY 1991 have been prepared based on activities approved by the Technical Steering Panel (TSP) in October 1990 and mid-year revisions discussed at the TSP planning/budget workshop in February 1991. The activities can be divided into two broad categories: (1) model and data development and evaluation, (2) project, technical and communication support. 3 figs., 1 tab.

    Electric power generating plants that use coal were among the key targets of Title IV of the 1990 Clean Air Act. Under the first phase of the act, 110 coal-fired electric power plants were required to reduce their sulfur dioxide emissions by 1995 and nitrogen oxide emissions by 1996. Phase 2 of the act requires even greater reduction of sulfur dioxide emissions by 2000 and nitrogen oxide emissions by 2008. This study examines whether the 107 targeted plants (three plants went off-line) have achieved the desired sulfur dioxide and nitrogen oxide emission levels. The analysis of sulfur dioxide is based on data from 1990, 1995, and 1999. The findings show that although sulfur oxide increased by 3% from 1995 to 1999, it decreased by 45% over the 1990-1999 period at the firm level for the targeted firms. The findings also indicate that the overall reduction in sulfur dioxide was achieved by utilizing low sulfur coal and by purchasing emission allowances. So far as nitrogen oxides are concerned, there has been a reduction of 14% over the 1990-1999 period, of which 7% was achieved during the 1995-1999 period. An evaluation of emissions at the plant level indicates that several plants do not meet the emissions level for sulfur dioxide or nitrogen oxides. These results provide a mixed scorecard for reduction in emissions both for sulfur dioxide and nitrogen oxides. Even though there is reduction in the emissions on an overall basis at the firm level, several plants that have not been able to reduce emissions deserve special attention to meet the goals of the act in reducing emissions.

    Multifrequency polarimetric synthetic aperture radar (SAR) images of the Walnut Gulch watershed near Tombstone, Arizona were acquired on 28 Mar. 1990 and on 1 Aug. 1990. Trihedral corner reflectors were deployed prior to both overflights to allow calibration of the two SAR data sets. During both overflights, gravimetric soil moisture and dielectric constant measurements were made. Detailed vegetation height, density, and water content measurements were made as part of the Monsoon 1990 Experiment. Preliminary results based on analysis of the multitemporal polarimetric SAR data are presented. Only the C-band data (5.7-cm wavelength) radar images show significant difference between Mar. and Aug., with the strongest difference observed in the HV images. Based on the radar data analysis and the in situ measurements, we conclude that these differences are mainly due to changes in the vegetation and not due to the soil moisture changes.

    Reduced softness and separation from the denture base are the most significant problems of long-term soft lining materials. The purpose of this study was to evaluate the durometer Shore A hardness and tensile bond strength of long-term soft denture lining materials and to investigate the correlation between these 2 properties. A group of 7 soft lining materials, 6 silicone based (Dentusil, GC Reline Soft, GC Reline Ultrasoft, Mucopren Soft, Mucosoft, Sofreliner Tough) and 1 acrylic resin based (Durabase), were evaluated for durometer Shore A hardness and tensile bond strength to heat-polymerized denture base resin (Lucitone 199). A specially designed split mold and loading assembly with a swivel connector were used for the durometer Shore A hardness test and tensile bond strength test to improve accuracy and facilitate measurement. Three specimens of each product were stored in a 37°C water bath, and durometer Shore A hardness tests were carried out after 24 hours and 28 days. A tensile bond strength test was carried out for 10 specimens of each product, which were stored in a 37°C water bath for 24 hours before the test. Repeated-measures ANOVA, the Kruskal-Wallis and Duncan multiple range tests, and the Spearman correlation were used for statistical analyses. The repeated-measures ANOVA found significant durometer Shore A hardness differences for the materials (P<.001) and the interaction effect (aging×materials) (P<.001). GC Reline Ultrasoft showed the lowest mean durometer Shore A hardness (21.30 ±0.29 for 24 hours, 34.73 ±0.47 for 28 days), and GC Reline Soft showed the highest mean durometer Shore A hardness (50.13 ±0.48 for 24 hours, 57.20 ±0.28 for 28 days). The Kruskal-Wallis test found a significant difference in the mean tensile bond strength values (P<.001). GC Reline Ultrasoft (0.82 ±0.32 MPa) and Mucopren Soft (0.96 ±0.46 MPa) had a significantly lower mean tensile bond strength (P<.05). GC Reline Soft had the highest mean tensile bond

    There are several well-established methods for obtaining beach profiles, and more accurate and precise high-tech methods are emerging. Traditional low-cost methods requiring minimal user skill or training are still popular among professionals, scientists, and coastal zone management practitioners. Simple methods are being developed with a primary focus on sand and gravel beaches. This paper describes a simple, low-cost, manual field method for measuring profiles of beaches, which is particularly suitable for muddy shores. The equipment is a type of flexible U-tube manometer that uses liquid columns in vertical tubes to measure differences in elevation; the supporting frame is constructed from wooden poles with base disks, which hold measuring scales and a PVC tube. The structure was trialed on a mudflat characterized by a 20-40-cm-thick surface layer of silt and clay, located at the Kutubdia Island, Bangladesh. The study results are discussed with notes on the method's applicability, advantages and limitations, and several optional modifications for different scenarios for routine profiling of muddy shores. The equipment can be used by one person or two people, and the accuracy of the method is comparable to those in other methods. The equipment can also be used on sandy or gravel beaches.
