This report summarizes the results of a survey of residential No. 2 distillate fuel (home heating oil) and liquefied petroleum gas (propane) prices over the 1995--1996 heating season in Michigan. The Michigan's Public Service Commission (MPSC) conducted the survey under a cooperative agreement with the US Department of Energy's (DOE) Energy Information Administration (EIA). This survey was funded in part by a grant from the DOE. From October 1995 through March 1996, the MPSC surveyed participating distributors by telephone for current residential retail home heating oil and propane prices. The MPSC transmitted the data via a computer modem to the EIA using the Petroleum Electronic Data Reporting Option (PEDRO). Survey results were published in aggregate on the MPSC World Wide Web site at http://ermisweb.state.mi.us/shopp. The page was updated with both residential and wholesale prices immediately following the transmission of the data to the EIA. The EIA constructed the survey using a sample of Michigan home heating oil and propane retailers. The sample accounts for different sales volumes, geographic location, and sources of primary supply

Full Text Available Summer activities in the 1991/92 austral summer and winter activities in 1992 of the 33rd Japanese Antarctic Research Expedition (JARE are described. The JARE-33 consisted of 16 members of the summer party and 37 members of the wintering party (one member of the wintering party returned with the summer party. Two Brazilian fish physiologists joined the summer party based on the exchange scientist program of the Antarctic Treaty. The icebreaker SHIRASE left Tokyo on 14 November 1991 and arrived at Breid Bay on 18 December, where the closing of Asuka Camp was completed. Then she headed to Syowa Station and arrived there on 4 January 1992. Transportation of cargo by helicopter to Syowa Station was carried out between 23 December 1991 and 18 January 1992. A total of 848t of cargo, including pipe transport of light oil (342kl and freight by oversnow vehicles (215t, were transported. A new central building was constructed from 23 December to 17 February as the start of an 8-year reintegration project of Syowa Station. Three generator engines of 200kVA capacity were overhauled. Concurrently, various research programs such as absolute gravity measurement and field surveys including inland oversnow traverse were performed. However, there were some problems with a super conducting gravity meter while the gravity meter was being tested for winter operation. Therefore, one scientist working on the gravity meter who planned to winter-over decided to leave Syowa Station with the gravity meter. all of the summer party left Syowa Station on 17 February and headed to Sydney, Australia, while oceanographic and marine biological observations were carried out on board. Members of the summer party of JARE-33 and the wintering party of JARE-32 returned to Narita by air on 27 March 1992. The wintering party of JARE-33 worked at Syowa Station from 1 February 1992 to 31 January 1993. The scientific research programs cover the following four major disciplines : (1 upper

Funding from Bonneville Power Administration was provided to the Oregon Department of Fish and Wildlife and the Clatsop County Economic Development Council's Fisheries Project to identify and develop terminal fishing opportunities. The 1991 and 1992 brood fingerling coho from Oregon Department of Fish and Wildlife hatcheries were successfully reared during the winter period to smolt stage in Youngs Bay utilizing floating net pens. Based on coded-wire-tag recoveries during 1991--93 from 2-week net-pen acclimation releases, total accountability of coho adults averaged 40,540 fish, with the Youngs Bay commercial harvest accounting for 39%. With reduced ocean harvest impacts during 1994 and 1995, 92% of 51,640 coho in 1994 and 68% of 23,599 coho in 1995 (based on coded-wire-tag recoveries) were accounted for in the Youngs Bay commercial fishery for combined 2-week and overwinter acclimation net-pen releases. Overwinter net-pen acclimation coho accounted for 35,063 and 15,775 coho adults in 1994 and 1995 with 93% and 68% accountable in the Youngs Bay commercial harvest. Based on coded-wire-tag recoveries, less than 1% of the adults resulting from releases at Youngs Bay net pens strayed to hatcheries, while none were recovered on spawning ground surveys during 1991--95. The highest survival rates were observed for 1991 and 1992 brood overwinter coho released in early May. Time of release, not rearing strategy, appears to be the determining factor affecting survival in Youngs Bay

1992-01-01

This paper reports that a midyear update of Salomon Bros. survey of the petroleum industry's 1992 exploration and production budgets pinpoints the ways operators are adjusting outlays to match the times. The New York financial firm's latest tally shows: Operators have made deep cuts in their 1992 US and Canadian E and P budgets since yearend 1991. Moderate increases budgeted earlier for E and P outside North America are intact. Many companies substantially underspent their budgets in first half 1992. In Salomon Bros. Largest survey---247 companies responded---operators the they were budgeting a 3.2% year to year decline in their 1992 worldwide E and P spending, compared with a 1.3% increase planned for 1992 in December 1991. The decline in spending falls entirely in North America. Preliminary indications suggest that 1993 E and P spending will be relatively flat in the US and flat to moderately increased in Canada. Elsewhere, spending should continue to rise steadily in 1993, Salomon Bros. The. Budgets exclude producing property purchases and merger or acquisition of other companies when possible

The spatial and temporal distributions of dengue cases reported during a 1991-1992 outbreak in Florida, Puerto Rico (population = 8,689), were studied by using a Geographic Information System. A total of 377 dengue cases were identified from a laboratory-based dengue surveillance system and georeferenced by their residential addresses on digital zoning and U.S. Geological Survey topographic maps. Weekly case maps were generated for the period between June and December 1991, when 94.2% of the dengue cases were reported. The temporal evolution of the epidemic was rapid, affecting a wide geographic area within seven weeks of the first reported cases of the season. Dengue cases were reported in 217 houses; of these 56 (25.8%) had between two and six reported cases. K-function analysis was used to characterize the spatial clustering patterns for all reported dengue cases (laboratory-positive and indeterminate) and laboratory-positive cases alone, while the Barton and David and Knox tests were used to characterize spatio-temporal attributes of dengue cases reported during the 1991-1992 outbreak. For both sets of data significant case clustering was identified within individual households over short periods of time (three days or less), but in general, the cases had spatial pattern characteristics much like the population pattern as a whole. The rapid temporal and spatial progress of the disease within the community suggests that control measures should be applied to the entire municipality, rather than to the areas immediately surrounding houses of reported cases. The potential for incorporating Geographic Information System technologies into a dengue surveillance system and the limitations of using surveillance data for spatial studies are discussed.

The goal of the Gas Research Institute Wetland Corridors Program is to identify representative impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of the survey July 1992, at the Mills Creek tributary crossing, Jefferson County, New York. Data were collected from three wetland communities along the 1991 pipeline and compared with predisturbance data obtained in a June 1991 survey. Within one year after pipeline installation, 50% of the soil surface of the ROW in the scrub-shrub community was covered by emergent vegetation. Average wetland values for the ROW in 1992 were lower than in 1991, indicating that the removal of woody plants resulted in a community composed of species with greater fidelity to wetlands. In the emergent marsh community after one year, the average percentage of surface covered by standing water was greater in the ROW than in the adjacent natural areas. The ROW in the forested wetland community also contained standing water, although none was found in the natural forest areas. The entire study site remains a wetland, with the majority of plant species in all sites being either obligate or facultative wetland species. Weighted and unweighted average wetland indices for each community, using all species, indicated wetland vegetation within the newly established ROW.

This book constitutes a portion of the primary documentation for the 1992 Pacific Northwest Residential Energy Survey, Phase I. The complete 33-volume set of primary documentation provides information needed by energy analysts and interpreters with respect to planning, execution, data collection, and data management of the PNWRES92-I process. Thirty of these volumes are devoted to different ``views`` of the data themselves, with each view having a special purpose or interest as its focus. Analyses and interpretations of these data will be the subjects of forthcoming publications. Conducted during the late summer and fall months of 1992, PNWRES92-I had the over-arching goal of satisfying basic requirements for a variety of information about the stock of residential units in Bonneville`s service region. Surveys with a similar goal were conducted in 1979 and 1983. This volume discerns the information by state. ``Selected crosstabulations`` refers to a set of nine survey items of wide interest (Dwelling Type, Ownership Type, Year-of-Construction, Dwelling Size, Primary Space-Heating Fuel, Primary Water-Heating Fuel, Household Income for 1991, Utility Type, and Space-Heating Fuels: Systems and Equipment) that were crosstabulated among themselves.

Cardiovascular diseases (CVD), both genetic and acquired, increase the risk of maternal death (MD) unless proper genetic/clinical counseling is provided and a multidisciplinary approach is adopted during pregnancy. In recent decades, there has been a significant increase in the number of women with CVD of child-bearing age and in the incidence of pregnancy among relatively older women. However, the impact of this phenomenon on MD has not been carefully investigated. This retrospective study compares the incidence and etiology of maternal deaths related to cardiovascular disease (MD-CVD) in Japan in 2010-2012 to that seen in 1991-1992. Seven cases of MD-CVD were reported in 1991-1992, compared to 15 in 2010-2012. In 2010-2012, the causes included aortic dissection (n=5), peripartum cardiomyopathy (n=3), sudden adult/arrhythmic death syndrome (n=2), acute cardiomyopathy (n=2), pulmonary hypertension (n=2), and myocardial infarction (n=1), and four of these causes were not encountered in 1991-1992. The incidence of MD over the total number of pregnancies decreased from 9.4 per 100,000 cases in 1990-1992 to 4.6 per 100,000 cases in 2010-2012 (pJapan over the past 20 years. Thus, it is of critical importance to better understand the etiologies and early signs of MD-CVD and to devise an effective management program for pregnancies complicated by CVD.

1993-04-01

In an annual survey of Manitoba's petroleum industry, data are presented on oil and natural gas leases and sales, geophysical activity, exploration and drilling activity, production, oil prices and sales value, royalties and taxes, direct revenues from oil exploration and development, reserves, industry expenditures, and oil fields. Throughout the report, explanations are given of the items covered. Descriptions are made of new developments, the oil market, oil policies, incentive programs, and industrial activities. During 1992, 28 wells were drilled, compared to 54 in 1991. Oil production was down ca 8% from 1991 levels, to 656,415 m 3 ; the value of the oil produced decreased 4% to ca $86.3 million; and provincial revenues from the oil industry decreased by 24%. Oil industry expenditures in the province were estimated at $58 million, down 16% from 1991. As of 4 January 1993, there were 11 oil fields and 120 non-confidential oil pools designated in Manitoba. Crude oil prices fluctuated throughout the year. In 1992, Manitoba's average crude oil price was $20.89/bbl, compared with 1991's average of $20.14/bbl. Manitoba Energy and Mines amended the Drilling Incentive Program to provide a 10,000 m 3 holiday volume for horizontal wells. 12 figs., 17 tabs

Swap your propane cylinder with SWOP

International Nuclear Information System (INIS)

Anon.

1997-01-01

A very successful propane cylinder exchange program operated by South Western Ontario Propane (SWOP) Inc., was described. The company specializes in propane cylinder exchange and in the refurbishing and marketing of top quality domestic and commercial propane cylinders. The company, currently operating out of Bradford, Ontario, was started in 1991. It employs a staff of 25 in peak season. It has some 200 exchange outlets throughout Ontario and has accepted outdated tanks from as far west as Manitoba and as far east as Quebec. A typical transaction involves bringing an empty cylinder to the nearest SWOP location and exchanging it for a full SWOP cylinder. SWOP does about 50,000 to 60,000 exchanges a year. For the consumer, the program is said to be cheaper, safer and more convenient than getting refills. As far as dealers are concerned operating a SWOP exchange outlet can add extra profits, attract new customers, and build additional consumer loyalty without the need for extra staff or additional indoor space. SWOP delivers full cylinders to exchange outlets on a weekly basis when it also picks up the empty cylinders. At dealer locations, the cylinders (full or empty) are stored in company -designed vandal-proof metal cages. Major expansion of the network of outlets and the cylinder refurbishing and refilling facilities are planned for 1998

He, C.; Zhao, W.; Edens, T.C.

1992-04-01

An environmental policy, planning, and management survey was conducted in the Saginaw Bay area in the Fall of 1991. The survey identified unemployment, factory closure and environmental quality degradation as the major economic and environmental problems in the area. Surface water contamination, excessive nutrients and zebra mussel infestation were the most serious problems affecting water quality. Soil erosion, excessive fertilization and pesticide applications were the most important non-point sources of water pollution. Toxic chemicals, phosphorus, suspended solids, heavy metals were the major water pollutants in the area. Pollution cleanup, land use planning, and control of zebra mussels were identified as the top implementation priorities for the area. Recommendations made by the respondents for improving environmental quality are summarized in the report.

1994-01-01

This document reports on the work done by the Separations Science and Technology Programs of the Chemical Technology Division, Argonne National Laboratory, in the period October 1991--March 1992. This effort is mainly concerned with developing the TRUEX process for removing and concentrating actinides from acidic waste streams contaminated with transuranic (TRU) elements. The objectives of TRUEX processing are to recover valuable TRU elements and to lower disposal costs for the nonTRU waste product of the process. Two other projects are underway with the objective of developing (1) a membrane-assisted solvent extraction method for treating natural and process waters contaminated by volatile organic compounds and (2) evaporation technology for concentrating radioactive waste and product streams such as those generated by the TRUEX process

In 1988, monitoring of radioactivity in upland lakes was initiated in areas of Ireland which had been subjected to highest deposition following the Chernobyl accident. The monitoring programme was continued in 1989 and extended in 1990 to include 25 lakes in 13 counties. This survey provided a comprehensive national picture of the distribution of Chernobyl contamination in Irish freshwater lakes. In 1991 and 1992, the monitoring programme concentrated on those lakes which had shown highest levels in the 1990 survey. This report details the results of the freshwater lake monitoring programme for the years 1988 - 1992. As assessment of the radiation doses to those consumers who include relatively large amounts of freshwater fish in their diet is also made

From October 1991 to February 1992, an outbreak of acute fever (in which thick blood films were negative for malaria) spread rapidly in the city of Djibouti, Djibouti Republic, affecting all age groups and both nationals and foreigners. The estimated number of cases was 12,000. The clinical features were consistent with a non-haemorrhagic dengue-like illness. Serum samples from 91 patients were analysed serologically for flavivirus infection (dengue 1-4, West Nile, yellow fever, Zika, Banzi, and Uganda-S), and virus isolation was attempted. Twelve strains of dengue 2 virus were isolated. Dengue infection was confirmed by a 4-fold or greater rise in immunoglobulin (Ig) G antibody in paired serum specimens, the presence of IgM antibody, or isolation of the virus. Overall, 46 of the suspected cases (51%) were confirmed virologically or had serological evidence of a recent flavivirus infection. Statistical analysis showed that the presence of a rash was the best predictor of flavivirus seropositivity. In November 1992, Aedes aegypti was widespread and abundant in several districts of Djibouti city. A serological study of serum samples collected from Djiboutian military personnel 5 months before the epidemic showed that only 15/177 (8.5%) had flavivirus antibodies. These findings, together with a negative serosurvey for dengue serotypes 1-4 and yellow fever virus performed in 1987, support the conclusion that dengue 2 virus has only recently been introduced to Djibouti.

Recovery of the coastal marine environment in the Gulf following the 1991 War-related oil spills

Readman, J.W.; Bartocci, J.; Tolosa, I.; Fowler, S.W.; Oregioni, B.

1996-01-01

Results from a 1991 rapid assessment survey to investigate the extent of hydrocarbon contamination resulting from the massive spillage of petroleum and the burning of oil wells revealed that war-related pollution in the Gulf was restricted to approximately 400 km from the sources. Subsequent surveys of the impacted zone were organized during 1992 and 1993 to investigate temporal changes in petroleum hydrocarbon contamination and recovery. At most locations by 1992, degradation had resulted in a composition (as determined by gas chromatography) dominated by an unresolved complex mixture, with only the most resistant resolved compounds surviving. Levels of contamination at impacted sites were generally shown to have decreased by approximately 50% between 1991 and 1992. A much lesser reduction in contamination was recorded for the period 1992 to 1993, and an increase in hydrocarbon concentrations was noted for stations in Kuwait and northern Saudi Arabia, possibly as a result of increased tanker activity and associated deballasting. PAH concentrations are shown to remain comparatively low, with oil rather than combustion being the major source. (author)

This study includes all deaths among drug addicts in the years 1991 (n = 219) and 1992 (n = 214) investigated at the three institutes of forensic medicine in Denmark. The results are compared with deaths among drug addicts in 1984-1985. The number of deaths among drug addicts increased by approximately 50% in 1991-1992 compared with 1984-1985. The increase was most significant among drug addicts over 35 years of age. The cause of death was intoxication in three-quarters of the cases in 1991-1992. In half of these cases heroin/morphine had caused death, while intoxications caused by methadone accounted for approximately 30% of the cases. In the metropolitan area the frequency of methadone intoxications increased significantly compared with 1984-1985, whereas the number of heroin/morphine intoxications did not change. Outside the metropolitan area, however, a significant increase in heroin/morphine intoxications was noticed. In all parts of the country the number of propoxyphene intoxications decreased to a few annual cases. The most commonly used drugs of abuse were heroin/morphine, diazepam and methadone, often in combination with alcohol.

Once the Federal Columbia River Power System provided all the power our customers needed and surplus energy, which we sold to others. However, we planned for the time when the surplus would disappear. With our customers, we developed centralized, region-wide conservation programs to conserve energy and build the knowledge and ability to save more energy when needed. We began to look at conservation as a resource, comparing it with supply-side alternatives. Much was accomplished. In Bonneville`s service area in the 1980s, our customers acquired 300 average megawatts (aMW) of conservation savings. How? By weatherizing about 240,000 homes, by making aluminum plants, other industrial plants and commercial buildings more efficient, and also by encouraging states to adopt energy-efficient building codes. Now, our energy surplus is gone. Our customers need energy, and in a hurry. While we plan how much energy will be needed, when and by which customers, we must concurrently accelerate our efforts to acquire resources. Our 1990 Resource Program launched a strategy to do just that, starting in 1991 and 1992, with continuing activities in 1993--1995. The goals and plans of the 1990 Resource Program are still being implemented.

Over the last 25 years, illicit cannabis use and cannabis use disorders have increased among US adults, and 28 states have passed medical marijuana laws (MML). Little is known about MML and adult illicit cannabis use or cannabis use disorders considered over time. To present national data on state MML and degree of change in the prevalence of cannabis use and disorders. Differences in the degree of change between those living in MML states and other states were examined using 3 cross-sectional US adult surveys: the National Longitudinal Alcohol Epidemiologic Survey (NLAES; 1991-1992), the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002), and the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III; 2012-2013). Early-MML states passed MML between NLAES and NESARC ("earlier period"). Late-MML states passed MML between NESARC and NESARC-III ("later period"). Past-year illicit cannabis use and DSM-IV cannabis use disorder. Overall, from 1991-1992 to 2012-2013, illicit cannabis use increased significantly more in states that passed MML than in other states (1.4-percentage point more; SE, 0.5; P = .004), as did cannabis use disorders (0.7-percentage point more; SE, 0.3; P = .03). In the earlier period, illicit cannabis use and disorders decreased similarly in non-MML states and in California (where prevalence was much higher to start with). In contrast, in remaining early-MML states, the prevalence of use and disorders increased. Remaining early-MML and non-MML states differed significantly for use (by 2.5 percentage points; SE, 0.9; P = .004) and disorder (1.1 percentage points; SE, 0.5; P = .02). In the later period, illicit use increased by the following percentage points: never-MML states, 3.5 (SE, 0.5); California, 5.3 (SE, 1.0); Colorado, 7.0 (SE, 1.6); other early-MML states, 2.6 (SE, 0.9); and late-MML states, 5.1 (SE, 0.8). Compared with never-MML states, increases in use were

Propane is used in most remote locations in North America for heat, cooking, power, or light. The users include ski hills operators to fishing lodges owners. Three profiles are presented in this article. The Pawistik Lodge is located in northern Saskatchewan near the Manitoba border. This lodge accommodates anglers. Propane is used for heating, gas stoves, lighting, and to power a one-ton truck, while electricity is used for all other energy needs. At Banff National Park, the clean burning fuel of choice for hot water, heating, cooking, and refrigeration is propane. Every location west of the town of Banff is fueled by propane. It includes the Sunshine and Lake Louise ski resorts, the Lake Louise village, Johnston's Canyon, as well as other locations. Some of the cabins used by the Park wardens have been equipped with solar panels to supply the energy required for lighting, but stoves in those cabins are powered by propane. Park vehicles are powered by propane when possible, and some are powered by dual fuel, propane and gasoline. It is all part of the government's green plan. The entire Yoho National Park is also fueled by propane. Sun Peaks ski resort operates an elaborate grid system and a plant that vaporizes propane for distribution. The price increase for propane earlier in 2001 did not adversely affect the resort since it buys its propane in bulk (it uses approximately two million litres of propane each year). Propane fuels heating, hot water, and fireplaces. The outdoor swimming pool is heated using propane. It attempts to implement from the lessons learned at the successful Whistler/Blackcomb ski resort, also fueled by propane.

Energy Information Administration quarterly coal report, October--December 1992

International Nuclear Information System (INIS)

1993-01-01

The United States produced just over 1 billion short tons of coal in 1992, 0.4 percent more than in 1991. Most of the 4-million-short-ton increase in coal production occurred west of the Mississippi River, where a record level of 408 million short tons of coal was produced. The amount of coal received by domestic consumers in 1992 totaled 887 million short tons. This was 7 million short tons more than in 1991, primarily due to increased coal demand from electric utilities. The average price of delivered coal to each sector declined by about 2 percent. Coal consumption in 1992 was 893 million short tons, only 1 percent higher than in 1991, due primarily to a 1-percent increase in consumption at electric utility plants. Consumer coal stocks at the end of 1992 were 163 million short tons, a decrease of 3 percent from the level at the end of 1991, and the lowest year-end level since 1989. US coal exports fell 6 percent from the 1991 level to 103 million short tons in 1992. Less coal was exported to markets in Europe, Asia, and South America, but coal exports to Canada increased 4 million short tons

1991-08-01

The Systems Engineering Management Plan for the DOE Office of Civilian Radioactive Waste Management, which defines the systems engineering process for the Federal Radioactive Waste System (FWMS), requires that systems studies to support the integration, evaluation, and optimization of the system be identified. These studies are generally directed toward further defining system or system-element functional requirements, including interface requirements, evaluating alternative system configurations or operational rules, or optimizing design features to achieve system integration. Because the decisions based on these studies are conducted within the overall configuration management process, a consistent and documented framework for the identification and conduct of systems studies must be available. A planned approach is needed so that results from defensible and referenceable systems analyses are available to make informed decisions in a timely manner. This Plan covers ''top level'' studies (i.e., those involving system requirements generally and the definition of requirements for system elements). This Plan is focused on the FY 1991 and 1992 period, and will be updated periodically as required to ensure its currency. Proposed systems studies for FY 1991 and 1992, their recommended timing, and their relations to one another, current studies, and major program milestones are identified. In general, only those studies supporting monitored retrievable storage (MRS) design requirements are recommended for immediate initiation. The studies are grouped into five major decision groups to allow scheduling to support specific decision windows. The proposed system studies schedule is generally a conservative one, with studies occurring early in or before the associated decision window. These proposed studies are described in this Plan. 16 refs., 6 figs., 2 tabs

Geotechnical Field Data and Analysis Report, July 1991--June 1992

International Nuclear Information System (INIS)

1993-01-01

The Geotechnical Field Data and Analysis Report documents the geotechnical data from the underground excavations at the Waste Isolation Pilot Plant (WIPP) located near Carlsbad, New Mexico. The data are used to characterize conditions, confirm design assumptions, and understand and predict the performance of the underground excavations during operations. The data are obtained as part of a routine monitoring program and do not include data from tests performed by Sandia National Laboratories (SNL), the Scientific Advisor to the project, in support of performance assessment studies. The purpose of the geomechanical monitoring program is to provide in situ data to support continuing assessments of the design for the underground facilities. Specifically, the program provides: Early detection of conditions that could compromise operational safety; evaluation of room closure to ensure retrievability of waste; guidance for design modifications and remedial actions; and data for interpreting the actual behavior of underground openings, in comparison with established design criteria. This Geotechnical Field Data and Analysis Report covers the period July 1, 1991 to June 30, 1992. Volume 1 provides an interpretation of the field data while Volume 2 describes and presents the data itself

This biological survey was performed to document the summer flora and fauna found along the haul road constructed as part of the remedial action for the quarry bulk waste. State and Federal species listed as threatened or endangered were noted if encountered while surveying. Sampling locations were equally spaced along the quarry haul road, and a survey for vegetation and birds conducted at each location. Bird observations were conducted as breeding bird surveys once in June of 1991, and again in June of 1992. Each year's survey includes two observations in the early morning and one late in the evening. Vegetation surveys were conducted in 1991 using quadrants and transects. mammal, reptile, and amphibian sightings were noted as encountered

Yucca Mountain Socioeconomic Project: The 1991 Nevada State telephone survey: Key findings

Flynn, J.H.; Mertz, C.K.; Slovic, P.

1991-05-01

The 1991 Nevada State Telephone Survey was implemented by Decision Research on behalf of the State of Nevada, Agency for Nuclear Projects/Nuclear Waste Project Office (NWPO) as part of an ongoing socioeconomic impact assessment study. The scope of this survey was considerably smaller than a previous survey conducted in 1989 and focused more upon public evaluations of the Yucca Mountain repository program and the trust Nevadans currently addressing the siting issues. In order to provide place in key public officials who are Longitudinal data on the repository program, the 1991 questionnaire consisted of questions that were used in the 1989 NWPO survey which was conducted by Mountain West Research. As a result, the findings from this survey are compared with analogous items from the 1989 survey, and with the results from a survey commissioned by the Las Vegas Review-Journal and reported in their issue of October 21, 1990. The Review-Journal survey was conducted by Bruce Merri11 of the Arizona State University Media Research Center. A more complete comparison of the 1989 and 1991 surveys sponsored by NWPO is possible since the researchers at Decision Research had access to both these databases. The only source of information for the Review-Journal findings was the articles published in the Fall, 1990. The findings of the 1991 survey show that Nevadans oppose the federal government attempts to locate a high-level radioactive waste repository at Yucca Mountain. They support a policy of opposition on the part of Nevada officials. They believe that Nevadans should have the final say in whether to accept the repository or not, and they reject the proposition that benefits from the repository program will outweigh the harms. These findings are very similar to survey results from 1989 and 1990 and once again demonstrate very widespread public opposition by Nevadans to the current federal repository program

Ground-water data collected from wells and test holes at and in the vicinity of the Nevada Test Site have been compiled in a recently released report. These data were collected by the US Geological Survey, Department of the Interior, in support of the US Department of Energy, Environmental Restoration and Hydrologic Resources Management Programs. Depth-to-water measurements were made at 53 sites at the Nevada Test Site from October 1, 1991, to September 30, 1992, and at 60 sites in the vicinity of the Nevada Test Site from 1952 to September 30, 1992. For water year 1992, depth to water ranged from 288 to 2,213 feet below land surface at the Nevada Test Site and from 22 to 1,460 feet below land surface at sites in the vicinity of the Nevada Test Site. Total ground-water withdrawal data compiled for 12 wells at the Nevada Test Site during calendar year 1992 was more than 400 million gallons. Tritium concentrations in water samples collected from five test holes at the Nevada Test Site in water year 1992 did not exceed the US Environmental Protection Agency drinking, water limit

Surveillance of radioactive substances around Finnish nuclear power plants continued in 1991-1992 according to regular monitoring programmes, in which about 1000 samples were analysed annually from terrestrial and aquatic environments of the two power plants. Trace amounts of activation products originating from the airborne releases of the local power plants were detected in several air, deposition and soil samples. Discharged nuclides were more abundant in the aquatic environment, especially in samples of indicator organisms, sinking matter and sediments. However, the concentrations were so low that they did not markedly increase the radiation burden in the environment. The dominant artificial radionuclides in the vicinity of the power plants remained the cesium isotopes, {sup 137}Cs and {sup 134}Cs, originating from the Chernobyl accident. (orig.)

The James Bay Advisory Committee on the Environment (JBACE) was established under the James Bay and Northern Quebec Agreement as the preferred, official form for the Quebec and Canadian governments as well as for aboriginal groups and territorial municipalities when they wish to formulate laws and regulations relating to the environment and social milieu of the territory falling under the Agreement. JBACE activities for 1991-92 included action regarding an environmental impact study of the Great Whale hydroelectric development project, an environmental assessment of a proposed 735-kV transmission line, language policies under the Agreement, and a study of forest management plans for the James Bay region. In response to a Quebec environmental ministry notice that planned access and accomodation infrastructures for the Great Whale project should have a separate environmental assessment, the JBACE had recommended that there should be only one assessment for all aspects of the Great Whale project. In January 1992, a memorandum of agreement was signed satisfying JBACE's requests on the environmental assessment. 1 fig., 1 tab

The present survey is a re-investigation of the sea bottom sediments at six sites in the Heidrun oil and gas field, May 1992. Petroleum hydrocarbons and heavy metals were at background levels. Compared to the baseline survey in 1988 values of hydrocarbons and barium were decreased. The sediment fauna was sparse with low numbers of species and individuals. Densities were strongly reduced and diversity decreased compared to 1988. There is no indication of anthropogenic factors or other large scale disturbances in the area to explain the faunal changes, which may reflect a large natural variation in the sediment fauna. 22 refs., 16 figs., 35 tabs

In a previous newsletter (September 1991 issue of this journal), the results of MVMA's 1990 Summer Gasoline Survey were discussed. It was noted that many gasolines containing high concentrations of olefins (over 15 percent volume) were being marketed in the northeast corridor between Washington, D.C. and Boston. Also noted was the finding that the composition of gasoline plays an important role in determining the emissions from vehicles on the road. In this newsletter, the potential effects on air quality of the more recently surveyed gasolines are discussed. Three grades of unleaded gasoline were covered in the survey (premium, intermediate, and regular). 1 tab

Wahl, L.

1993-10-01

This report summarizes, by radionuclide or product and by emitting facility, the Laboratory's 1992 radioactive air emissions. In 1992, the total activity of radionuclides emitted into the air from Laboratory stacks was approximately 73,500 Ci. This was an increase over the activity of the total 1991 radioactive air emissions, which was approximately 62,400 Ci. Total 1992 Laboratory emissions of each radionuclide or product are summarized by tables and graphs in the first section of this report. Compared to 1991 radioactive air emissions, total tritium activity was decreased, total plutonium activity was decreased, total uranium activity was decreased, total mixed fission product activity was increased, total 41 Ar activity was decreased, total gaseous/mixed activation product (except 41 Ar) activity was increased, total particulate/vapor activation product activity was increased, and total 32 P activity was decreased. Radioactive emissions from specific facilities are detailed in this report. Each section provides 1992 data on a single radionuclide or product and is further divided by emitting facility. For each facility from which a particular radionuclide or product was emitted, a bar chart displays the air emissions of each radionuclide or product from each facility over the 12 reporting periods of 1992, a line chart shows the trend in total emissions of that radionuclide or product from that facility for the past three years, the greatest activity during the 1990--1992 period is discussed, and unexpected or unusual results are noted

New perspectives on auto propane

International Nuclear Information System (INIS)

Webb, R.F.

1991-01-01

In spite of the high level of propane use in vehicles in North America (relative to the use of compressed natural gas (CNG) or methanol), the alternate-fuel research and development activities of original equipment manufacturers (OEMs) are focusing on methanol, CNG, and electric vehicles. If OEM indifference to propane continues, propane vehicles will continue to be available only in after-market conversions, denying propane the benefits of OEM mass-production economics, quality control, retail distribution, and other factors. Recent developments in auto propane are reported which should be considered by OEMs and policymakers to allow propane to enter the mass-scale motor vehicle market. Propane and the liquefied petroleum gas (LPG) mix used as a motor vehicle fuel are often regarded as just a byproduct of natural gas production and oil refining, giving the impression that propane/LPG will not be available in sufficient quantities to support a mass market. It is shown that LPG supply is market-responsive and that over 20 billion gal of new supply could be made available from North American sources by the year 2000 and over 27 billion gal by 2005, sufficient to supply 12.5% of the projected North American vehicle fleet in 2005. The new supply would come from incremental expansion of existing production, displacement of LPG from lower-value uses, and LPG synthesis. The environmental performance of propane/LPG engines is also compared to that of engines running on gasoline, natural gas, and methanol. Advantages of LPG over gasoline include lower carbon content and lower CO emissions, and advantages over CNG arise from the high greenhouse gas activity and long life of methane. 12 figs

Heavy-Section Steel Irradiation Program: Volume 3, Progress report, October 1991--September 1992

Corwin, W.R.

1995-02-01

The primary goal of the Heavy-Section Steel Irradiation Program is to provide a thorough, quantitative assessment of the effects of neutron irradiation on the material behavior, and in particular the fracture toughness properties, of typical pressure vessel steels as they relate to light-water reactor pressure-vessel integrity. Effects of specimen size, material chemistry, product form and microstructure, irradiation fluence, flux, temperature and spectrum, and postirradiation annealing are being examined on a wide range of fracture properties. The HSSI Program is arranged into 10 tasks: (1) program management, (2) K Ic curve shift in high-copper welds, (3) K Ia curve shift in high-copper welds, (4) irradiation effects on cladding, (5) K Ic and K Ia curve shifts in low upper-shelf welds, (6) irradiation effects in a commercial low upper-shelf weld, (7) microstructural analysis of irradiation effects, (8) in-service aged material evaluations, (9) correlation monitor materials, and (10) special technical assistance. This report provides an overview of the activities within each of these tasks from October 1991 to September 1992

Parental compliance - an emerging problem in Liverpool community child health surveys 1991-2006

Directory of Open Access Journals (Sweden)

2012-04-01

Full Text Available Abstract Background Compliance is a critical issue for parental questionnaires in school based epidemiological surveys and high compliance is difficult to achieve. The objective of this study was to determine trends and factors associated with parental questionnaire compliance during respiratory health surveys of school children in Merseyside between 1991 and 2006. Methods Four cross-sectional respiratory health surveys employing a core questionnaire and methodology were conducted in 1991, 1993, 1998 and 2006 among 5-11 year old children in the same 10 schools in Bootle and 5 schools in Wallasey, Merseyside. Parental compliance fell sequentially in consecutive surveys. This analysis aimed to determine the association of questionnaire compliance with variation in response rates to specific questions across surveys, and the demographic profiles for parents of children attending participant schools. Results Parental questionnaire compliance was 92% (1872/2035 in 1991, 87.4% (3746/4288 in 1993, 78.1% (1964/2514 in 1998 and 30.3% (1074/3540 in 2006. The trend to lower compliance in later surveys was consistent across all surveyed schools. Townsend score estimations of socio-economic status did not differ between schools with high or low questionnaire compliance and were comparable across the four surveys with only small differences between responders and non-responders to specific core questions. Respiratory symptom questions were mostly well answered with fewer than 15% of non-responders across all surveys. There were significant differences between mean child age, maternal and paternal smoking prevalence, and maternal employment between the four surveys (all p Conclusion Methodological differences or changes in socio-economic status of respondents between surveys were unlikely to explain compliance differences. Changes in maternal employment patterns may have been contributory. This analysis demonstrates a major shift in community parental

The outlook for oil prices in 1992 - results of a survey

Hawdon, D.

1992-01-01

The eighth in a series of oil price expectation studies took place on 18th March 1992 at the Prospects for Oil Prices conference held at the University of Surrey. Thirty-one participants returned a questionnaire designed to elicit 12 month ahead and 5 year ahead price expectations. Respondents were asked to indicate their view of the likely price of oil in certain broad price ranges. These were selected to cover the wide variation of prices experienced since the early 1970s. The results show the 12 month's ahead expectations all clustered in the range $10 to $25 per barrel and $16-$20 as the median predicted price. In comparison with the 1991 expectations, a much higher proportion of respondents (77.4 as compared to 50% in 1991) gave $16-20 as their expected price range, whilst fewer expected prices to rise (19% compared with 46% in 1991). The stability of the 12 month ahead price expectations is a remarkable feature of a period which has witnessed much tension in the Middle East and in the former Soviet Union. This stability extends to the 5 year ahead forecasts as well. Here the median expectation is for prices to rise to the $21-25 per barrel range in money of the day terms though there is evidence of a growing scepticism about the oil market's ability to sustain higher prices in the long run.

1995-05-01

During the 1994--95 heating season, the Massachusetts Division of Energy Resources (DOER) participated in a joint data collection program between several state energy offices and the federal Department of Energy's (DOE) Energy Information Administration (EIA). The purpose of the program was to collect and monitor retail and wholesale heating oil and propane prices and inventories from October 1994 through March 1995. This program augmented the existing Massachusetts data collection system and served several important functions. The information helped the federal and state governments respond to consumer, congressional and media inquiries regarding No. 2 oil and propane. The information also provided policy decision-makers with timely, accurate and consistent data to monitor current heating oil and propane markets and develop appropriate state responses when necessary. In addition, the communication network between states and the DOE was strengthened through this program. This final report begins with an overview of the unique events that had an impact on the petroleum markets prior to and during the reporting period. Next, the report summarizes the results from residential heating oil and propane price surveys conducted by DOER over the 1994--95 heating season. The report also incorporates the wholesale heating oil and propane prices and inventories collected by EIA and distributed to the states. Finally, the report outlines DOER's use of the data

Propane supply picture: North American perspective

International Nuclear Information System (INIS)

Horner, N.

1992-01-01

An overview is presented of the North American propane supply and demand situation. Propane has a distribution network in place and a well established market. North America is virtually self-sufficient in propane with a market of over 1,000,000 bbl/d. Approximately 80% of Canada's propane supply is produced at gas plants in western Canada as a byproduct of natural gas production. The expansion in natural gas markets will mean that propane supply will rise further, unlike crude oil. Canada's daily supply of nearly 160,000 bbl is used for heating (30%), transport (12%), petrochemicals (7.8%), and enhanced oil recovery (4.7%), with the remainder being exported. Propane surpluses are expected to grow, between 70,000 and 100,000 bbl/d in the next 5 years. Nearly 30% of North America's demand for propane is in the petrochemical industry, for which various other feedstocks can be substituted. An availability of over 400,000 bbl/d could fuel ca 5 million vehicles. Only natural gas has a comparable infrastructure and this suffers from high utilization pressure and poor energy density. Wholesale propane is now available at under 9 cents/liter, significantly below the projected ethanol price of 18 cents/liter, which excludes grain feedstock or capital cost. 8 refs., 6 figs

On a world average basis, gasoline and diesel No. 2 prices to consumers declined modestly between January 1991 and January 1992, Energy Detente's survey finds. The drops were in response to falling crude oil prices that followed the conclusion of the Persian Gulf War. Demand increases in 1991, where they occurred, are expected to continue in the short term. This issue details price changes by country and highlights causes in selected countries. Sizable oil-consumption declines in the former USSR and Eastern Bloc countries mask substantial increases among European member nations of OECD.

NUKEM estimates that world uranium production fell more than 13% last year, from 40,729 tonnes U [106 million lbs U308] in 1991 to 35,363 tonnes U [92 million lbs U308] in 1992. Production fell in both the Western World and non-Western World. How much of demand was met by production? World uranium production in 1992 amounted to about 65% of reactor consumption. That's assuming that reactor demand of the non-Western World has not changed much from the Uranium Institute's estimate for 1991. Civilian stockpiles are being drawn down on a massive scale while the world waits to see what will become of the military stockpiles that could soon enter the global supply picture

1993-05-01

The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketeer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. 1992 marked the end of chronically depressed natural gas prices and a significant reduction in natural gas surpluses. A brief overview is presented of crude oil markets in Canada and the USA. The Commission's receipts of light and medium royalty oil totalled 45.3 million bbl, unchanged from 1991, and receipts of heavy crude were 6.3 million bbl, up 4% from 1991. Revenue from crude oil sales was $1.1 billion, down from $1.64 billion in 1991. The Commission's natural gas activities in 1992 included price determination and information collection. 9 figs., 1 tab

Throughout the report, explainations are given of the items covered. Descriptions are made of new developments, the oil market, oil policies, incentive programs, and industrial activities. During 1991, 54 wells were drilled, compared to 79 in 1990. Oil production was down ca 3% from 1990 levels, to 712,792 m 3 , the value of the oil produced decreased 21% to ca $90.3 million, and provincial revenues from the oil industry declined by 15%. Oil industry expenditures in the province were estimated at $69 million, down 9% from 1990. As of the end of 1991, there were 11 oil fields and 118 non-confidential oil pools designated in Manitoba. The forecast for 1992 indicates that exploration activity will increase in response to new incentive programs. Crude oil production is expected to decline slightly to about 667,000 m 3 . 9 figs., 17 tabs

In the past, providing electric power in rural areas in America was accomplished in a pre-determined manner. Electric cooperatives acted as distribution companies that maintained poles and wires, and ensured that the rural customer (home, business, etc.) always had power. Things are about to change, due to electricity market deregulation and the emergence of distributed generation. Electric cooperatives are adjusting by moving to propane. The challenges facing electric cooperatives are a bit daunting. The cooperatives were customer-service oriented strongly committed to their region, where the customer had no other purchasing option. The electric cooperatives seldom deviated from their cost plus pricing plan. Suddenly, with the prospect of marketing propane, a number of retailers are after the same customers. The emphasis is now on customer service and pricing plans. Payment options and other services must be offered in addition to fair pricing to gain or retain a slight advantage that might make the difference between survival and bankruptcy. Retailer must be careful not to speculate on the price of propane when devising their pricing plans. They must be aware of the supply plans. Reliability is also expected by the propane customers. Some of the tips offered: a proper understanding of the differences that underlay electricity and propane marketing, and react accordingly; use marketing to build propane relationships; offer the service to current electric members first; experience is vital in the field of propane; know your numbers; risk management and supply marketing are notions worth knowing; and finally know the competition

Activities related to revitalisation of the RA reactor stared in 1986, were continued in 1991. A number of interventions on the reactor components were finished that are supposed to enable continuous and reliable operation. The last, and at the same time largest action, related to exchange of complete reactor instrumentation is underway, but it is behind the schedule in 1991 because the delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Only 56% of the instrumentation was delivered until September 1991. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA. In 1991 most of the existing RA reactor instrumentation was dismantled, only the part needed for basic measurements when reactor is not operated, was maintained. Construction of some support elements is almost finished by the local staff. The Institute has undertaken this activity in order to speed up the ending of the project. If all the planned instrumentation would not arrive until the end of March 1992, it would not be possible to start the RA reactor testing operation in the first part of 1993, as previously planned. In 1991, 53 staff members took part in the activities during 1991, which is considered sufficient for maintenance and repair conditions. Research reactor RA Annual report for year 1991 is divided into two main parts to cover: (1) operation and maintenance and (2) activities related to radiation protection.

A propane price spike nails users

Milke, M.

1997-01-01

The increase in price for propane was discussed. In 1993, propane cost about 5 cents per litre; by December 1996, the price has risen to 27 cents wholesale, while retail prices for auto propane reached 40 cents per litre. As a result, farmers and fleet operators are considering switching to an alternative energy supply. The five factors which may have played a role in the propane price spike were described. These included a cold winter which lowered inventories, a Pemex gas plant in Mexico which had been damaged by fire, forcing Mexico to import natural gas and natural gas liquids from the USA, the failure of propane distributors to restock during the summer months in the hope of lower prices, and increased cost of competing fuels in the face of increased demand. It was noted that these factors are transitory, which could mean better prices this summer

The Devonian oil shales of the Eastern United States are a significant domestic energy resource. The overall objective of the multi-year program, initiated in October 1987 by the US Department of Energy is to perform the research necessary to develop the Pressurized Fluidized-Bed Hydroretorting (PFH) process for producing oil from Eastern oil shales. The program also incorporates research on technologies in areas such as raw shale preparation, beneficiation, product separation, and waste disposal that have the potential of improving the economics and/or environmental acceptability of recovering oil from oil shales using the PFH process. The results of the original 3-year program, which was concluded in May 1991, have been summarized in a four-volume final report published by IGT. DOE subsequently approved a 1-year extension to the program to further develop the PFH process specifically for application to beneficiated shale as feedstock. Studies have shown that beneficiated shale is the preferred feedstock for pressurized hydroretorting. The program extension is divided into the following active tasks. Task 3. testing of process improvement concepts; Task 4. beneficiation research; Task 5. operation of PFH on beneficiated shale; Task 6. environmental data and mitigation analyses; Task 7. sample procurement, preparation, and characterization; and Task 8. project management and reporting. In order to accomplish all the program objectives, the Institute of Gas Technology (IGT), the prime contractor, worked with four other institutions: the University of Alabama/Mineral Resources Institute (MRI), the University of Kentucky Center for Applied Energy Research (UK-CAER), the University of Nevada (UN) at Reno, and Tennessee Technological University (TTU). This report presents the work performed during the program extension from June 1, 1991 through May 31, 1992.

Lawrence Livermore National Laboratory (LLNL) Site 300 is located in the Altamont Hills between Livermore and Tracy, about 18 road miles southeast of Livermore, California. The site is used as a test facility to support national defense research carried out by LLNL. This Addendum 2 to the Logs of Wells and Boreholes Drilled During Hydrogeologic Studies at Lawrence Livermore National Laboratory Site 300 presents hydrogeologic logs for monitor wells and boreholes drilled primarily between January 1, 1991 and September 1, 1992. Some logs drilled earlier and not incorporated in earlier volumes of this document are also included here. A small number of logs drilled before September 1, 1992, are not available at the time of closing the report for publication of this volume (Addendum 2), but will be included in subsequent documents. By September 1, 1992, a total of 495 monitor wells and 285 exploratory boreholes had been drilled at Site 300 since the beginning of hydrogeologic studies in 1982. The primary purpose of these logs is to document lithologic and hydrogeologic conditions together with well completion information. For this reason, not all chemical analytical data are presented. These logs report concentrations of only the most commonly encountered volatile organic compounds, trace metals, and radionuclides detected in ground water and soil samples collected during drilling

We review the history of degassing, bathymetry and water chemistry of the crater lake of Mt. Pinatubo (Philippines) using data obtained during 1991-2001, and 2010. In late 1992, the initial small lake had a significant acid-sulfate component from a volcanic degassing through a hydrothermal system and the lake, and anhydrite dissolution. Subsequently, this component was "drowned" by rainfall (2-4 m/y), meteoric groundwater draining from the crater walls into the lake, and a few neutral chloride crater wall springs. Conductivity-Temperature-Depth (CTD) measurements in August 2000 found a strong inverted thermal gradient below 20m depth, reaching over 70°C at 50-60 m depth. By January 2001 the lake had homogenized and was much cooler (27°C at all depths), and it was again well-mixed and still cool when re-surveyed in June 2001 and November 2010. By 2010, the lake was well mixed, at neutral pH, with no significant vertical or horizontal structure. Bubbling of a predominantly carbon dioxide (CO2) gas phase persists throughout the lake's history, some from 1991-92 magma and some from degassing of the long-standing (pre-1991) hydrothermal system fed from a deeper magmatic or mantle source. Crater wall fumaroles emit boiling-point hydrothermal gases dominated by water, air, and CO2.

Full Text Available For most of Antarctica, the geophysical data now available are those of aeromagnetic surveys performed there from 1950 to 1960. Until 1984, the inaccurate positioning and insufficient monitoring of geomagnetic time variations allowed the investigation of the geomagnetic residual field only along profiles. The Ganovex IV aeromagnetic survey, performed by BGR-USGS over the Ross Sea and the Northern Victoria Land, and the geophysical investigations of BAS on the Southern Antarctic peninsula and the Ronne ice shelf region corresponds to the recent advancement of these techniques in Antarctica. The first experiments of aeromagnetic measurements, during the Italian expeditions in Antarctica were made during the 1988-1989 field season. Some geomagnetic helicopter borne profiles were accomplished with a Proton Precession Magnetometer (PPM in the Terra Nova Bay-Gerlache Inlet area. In the 1989-1990 ItaliAntartide expedition some profiles were flown over the suture between the Wilson and Bower terranes, in Northern Victoria Land. During the 1991-1992 expedition, in cooperation with researchers of BGR (Bundesanstalt fur Geowissenschaften und Rohstoffe of Hannover, the GITARA I (German ITalian Aeromagnetic Rescarch Antarctica program, as part of the LIRA (Litospheric Investigation in the Ross Sea Area project, was carried out. The investigated area lies between the latitudes 74°18' S and 75°18' S and the longitudes 160°30' E and 164°30'E and it corresponds to a portion of the North Victoria Land, located between the Eisenhower Range and the, DrygaIski Ice Tongue. The survey was made with a Cesium vapour magnetometer. The positioning system was of the “Range-Range” type, it consisted of three transmitters (beacons, installed inside the investigated area and located with GPS measurements. The line spacing was 4.4 km, with tie lines every 22 km. The survey covered an area of 6500 km2 . Four PPM base stations for the determination of the time variation

1991 annual report on low-level radioactive waste management progress

International Nuclear Information System (INIS)

1992-11-01

This report summarizes the progress during 1991 of States and compact regions in establishing new low-level radioactive waste disposal capacity. It has been prepared in response to requirements in Section 7 (b) of Title I of Public Law 99-240, the Low-Level Radioactive Waste Policy Amendments Act of 1985 (the Act). By the end of 1991, 9 compact regions (totaling 42 States) were functioning with plans to establish low-level radioactive waste disposal facilities: Appalachian, Central, Central Midwest, Midwest, Northeast, Northwest, Rocky Mountain, Southeast, and Southwestern. Also planning to construct disposal facilities, but unaffiliated with a compact region, are Maine, Massachusetts, New York, Texas, and Vermont. The District of Columbia, New Hampshire, Puerto Rico, Rhode Island and Michigan are unaffiliated with a compact region and do not plan to construct a disposal facility. Michigan was the host State for the Midwest compact region until July 1991 when the Midwest Interstate Compact Commission revoked Michigan's membership. Only the Central, Central Midwest, and Southwestern compact regions met the January 1, 1992, milestone in the Act to submit a complete disposal license application. None of the States or compact regions project meeting the January 1, 1993, milestone to have an operational low-level radioactive waste disposal facility. Also summarized are significant events that occurred in low-level radioactive waste management in 1991 and early 1992, including the 1992 United States Supreme Court decision in New York v. United States in which New York challenged the constitutionality of the Act, particularly the ''take-title'' provision. Summary information is also provided on the volume of low-level radioactive waste received for disposal in 1991 by commercially operated low-level radioactive waste disposal facilities

It is being organized by the industry to allow for the realization of the full potential of propane as a safe and environmentally appropriate fuel. The program represents a new way of doing business by encouraging an industry-wide commitment to quality and performance. In terms of products, the program covers propane and propane transporting, storing, consuming and servicing products and services. A Code of Practice is currently being drawn up, and members will be asked to commit to the Code and implement it through a Quality Management Program. An annual fee-for-service-based audit of performance is envisaged. Expected benefits of the program include better management of costs, incident and accident reduction, greater customer satisfaction, increased credibility with government and the public, and greater employee satisfaction. Implementation is planned for June 30, 1998.

Full Text Available The coverage of maternal health care services have been reviewed from the Demographic and Health Survey (IDHS conducted in 1991, 1994 and 1997, which covered live births delivered within 5 years preceding the survey. In general the coverage of maternal health care -- during pregnancy and delivery -- have improved. According to the result of the survey, consisting of births in 1992-1997; the coverage of antenatal care has almost reached 90%, which is the target/goal of the Sixth Five Years Development (1994-1998. However, four in five births are still delivered at home and 70% deliveries are assisted by non-health professionals, comparing to the results of IDHS 1991 and 1994 the coverage of safe delivery increases slowly. A great discrepancy of safe delivery coverage was observed between urban/rural areas as well as between Java-Bali/Outer Java-Bali regions. Fifty three percent births were to mothers who got two tetanus toxoid injections during pregnancy, and 72%. were to mother with at least one tetanus toxoid injection. The discrepancy of tetanus toxoid immunization coverage between urban/rural areas as well as between Java-Bali/Outer Java-Bali regions had slightly decreased.

French parapetroleum industry: results of 1992 survey

International Nuclear Information System (INIS)

Valentin, E.; Trouve, O.

1992-01-01

The petroleum prospection and production industries have developed a parapetroleum sector that is considerable in size and has been going through profound changes over the past few years. Under the impetus of acquisitions and mergers, the supply has become heavily concentrated, and now reorganized around a growing demand for integrated services. Petroleum companies tend to farm out a growing portion of their business, and this sharing out of competence and sometimes of responsibilities is breeding new types of partnership arrangements between the petroleum and parapetroleum business. This paper gives the results of an survey led in 1991 on petroleum international economy and gives statistical informations on french parapetroleum industry (exploration-production investments, exploratory wells drilled, drilling equipment in action, offshore operations, turnover evolution, shortage of manpower). 14 figs., 5 tabs

Confined zone dispersion flue gas desulfurization demonstration. Quarterly report No. 8, August 17, 1992--November 16, 1992

Energy Technology Data Exchange (ETDEWEB)

1993-09-27

The CZD process involves injecting a finely atomized slurry of reactive lime into the flue gas duct work of a coal-fired utility boiler. The principle of the confined zone is to form a wet zone of slurry droplets in the middle of the duct confined in an envelope of hot gas between the wet zone and the duct walls. The lime slurry reacts with part of the SO{sub 2} in the gas, and the reaction products dry to form solid particles. A solids collector, typically an electrostatic precipitator (ESP) downstream from the point of injection, captures the reaction products along with the fly ash entrained in the flue gas. The goal of this demonstration is to prove the technical and economic feasibility of the CZD technology on a commercial scale. The process is expected to achieve 50% SO{sub 2} removal at lower capital and O&M costs than other systems. To achieve its objectives, the project is divided into the following three phases: Phase 1: Design and Permitting, Phase 2: Construction and Start-up, Phase 3: Operation and Disposition. Phase 1 activities were completed on January 31, 1991. Phase 2 activities were essentially concluded on July 31, 1991, and Phase 3a, Parametric Testing, was initiated on July 1, 1991. This Quarterly Technical Progress Report covers Phase 3b activities from August 17, 1992 through November 16, 1992.

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.

Clunie, G.; Ell, P.J.

1995-01-01

We have evaluated radiation synovectomy practice in Europe over the period 1991-1993 by means of a postal questionnaire. More than 2300 European members of the European Association of Nuclear Medicine were questioned about the number of treated patients and joints, disease prevalence in their patients and the use of radiopharmaceuticals. Overall, 119/490 (24%) of centres replying to the survey practised radiation synovectomy during the 3 years. There were 13450 different joint injections in 8578 patients. Rheumatoid arthritis was the most prevalent disease in patients treated (71%) and the most frequently treated joints were knee (46%) and finger joints (20%). Eight different radiopharmaceuticals were employed. Yttrium-90 colloids were most frequently and widely (100/119 centres) used, mainly employed for knee synovectomy but were also used to treat most appendicular joints. Erbium-169 colloid was almost exclusively used to treat finger joints (31/33 centres). Corticosteroid was routinely co-injected in 36/60 (60%) centres. Radiation synovectomy was widely practised throughout Europe during 1991-1993. There are variations in practice illustrated by the diversity of treated arthritides and injected joints and by the use and application of different radiopharmaceuticals. (orig.).

Marine environmental radioactivity surveys at nuclear submarine berths in the UK 1991

International Nuclear Information System (INIS)

1992-06-01

This report presents the results of the marine environmental radioactivity monitoring surveys of intertidal and underwater areas around nuclear submarine berths in the UK, including the US Naval Base at Holy Loch, which were carried out by DRPS during 1991. Also included are results of smaller scale intertidal surveys carried out by local staff but co-ordinated by DRPS and, as an Appendix, a report by the US Navy detailing the results of their environmental monitoring programme at Holy Loch. Cobalt-60, the nuclide of major importance in naval discharges, was detected in a number of samples but in many cases was attributable to discharges by other operators. Concentrations in any case were found to be low, and at no survey location did the calculated annual radiation dose commitment to the most exposed members of the general public due to the presence of cobalt-60 exceed 1% of the ICRP principal dose limit for members of the public (1000 μSv). These results are consistent with those obtained in the independent monitoring programme undertaken by the Ministry of Agriculture Fisheries and Food Directorate of Fisheries Research. It is concluded that existing discharge arrangements are providing effective control over environmental levels of cobalt-60, and that there has been no radiological hazard to any member of the general public during 1991 from the operation of nuclear powered submarines.

1993-01-01

Petro-Canada was formed as Canada's national energy corporation by an act of Parliament in 1975. Operations began in January 1976, and the company was privatized in July 1991. In 1992, Petro-Canada markedly improved its operating performance by sharply cutting operating and overhead costs. Strategy in the company's resource division was refocused to concentrate future investment in western Canada light oil and natural gas and in Grand Banks light oil. Petro-Canada sold a 5% interest in the Syncrude oil sands project for $132 million as part of its plan to rebalance its portfolio. In the products division, Petro-Canada is reducing capacity and eliminating inefficient parts of its marketing network as a response to low demand. Operating earnings improved $252 million to reach $109 million, versus a $143 million loss in 1991. Net earnings were $9 million, compared to a $598 million loss in 1991. Total oil and natural gas liquids production was 80,000 bbl/d and natural gas production was 517 million ft 3 /d. Refined product sales were 43,000 m 3 /d at an average refinery utilization of 72%. Proved oil and natural gas liquids reserves were 417 million bbl and proved natural gas reserves were 2.4 trillion ft 3 . Debt was reduced by almost $700 million during 1992. The year's activities in production and sales of natural gas, synthetic and natural crude oil, gasoline, and oil sands are summarized. A 6-year operating and financial summary is included, along with a financial statement. 11 figs., 17 tabs

Commercial Buildings Characteristics 1992 presents statistics about the number, type, and size of commercial buildings in the United States as well as their energy-related characteristics. These data are collected in the Commercial Buildings Energy Consumption Survey (CBECS), a national survey of buildings in the commercial sector. The 1992 CBECS is the fifth in a series conducted since 1979 by the Energy Information Administration. Approximately 6,600 commercial buildings were surveyed, representing the characteristics and energy consumption of 4.8 million commercial buildings and 67.9 billion square feet of commercial floorspace nationwide. Overall, the amount of commercial floorspace in the United States increased an average of 2.4 percent annually between 1989 and 1992, while the number of commercial buildings increased an average of 2.0 percent annually.

Enhancement of LNG plant propane cycle through waste heat powered absorption cooling

Rodgers, P.; Mortazavi, A.; Eveloy, V.; Al-Hashimi, S.; Hwang, Y.; Radermacher, R.

2012-01-01

In liquefied natural gas (LNG) plants utilizing sea water for process cooling, both the efficiency and production capacity of the propane cycle decrease with increasing sea water temperature. To address this issue, several propane cycle enhancement approaches are investigated in this study, which require minimal modification of the existing plant configuration. These approaches rely on the use of gas turbine waste heat powered water/lithium bromide absorption cooling to either (i) subcool propane after the propane cycle condenser, or (ii) reduce propane cycle condensing pressure through pre-cooling of condenser cooling water. In the second approach, two alternative methods of pre-cooling condenser cooling water are considered, which consist of an open sea water loop, and a closed fresh water loop. In addition for all cases, three candidate absorption chiller configurations are evaluated, namely single-effect, double-effect, and cascaded double- and single-effect chillers. The thermodynamic performance of each propane cycle enhancement scheme, integrated in an actual LNG plant in the Persian Gulf, is evaluated using actual plant operating data. Subcooling propane after the propane cycle condenser is found to improve propane cycle total coefficient of performance (COP T ) and cooling capacity by 13% and 23%, respectively. The necessary cooling load could be provided by either a single-effect, double-effect or cascaded and single- and double-effect absorption refrigeration cycle recovering waste heat from a single gas turbine operated at full load. Reducing propane condensing pressure using a closed fresh water condenser cooling loop is found result in propane cycle COP T and cooling capacity enhancements of 63% and 22%, respectively, but would require substantially higher capital investment than for propane subcooling, due to higher cooling load and thus higher waste heat requirements. Considering the present trend of short process enhancement payback periods in the

McKinley Bay is a shallow protected bay along the eastern Beaufort Sea coast which provides an important habitat for diving ducks. Since 1979, the bay has been the site of a winter harbor and support base for oil and gas exploraton in the Beaufort Sea. Aerial surveys for bird abundance and distribution were conducted in August 1991 as a continuation of long-term monitoring of birds in McKinley Bay and Hutchison Bay, a nearby area used as a control. The main objectives of the 1991 surveys were to expand the set of baseline data on natural annual fluctuations in diving duck numbers, and to determine if numbers of diving ducks had changed since the initial 1981-85 surveys. On the day with the best survey conditions, the population of diving ducks at McKinley bay was estimated at ca 32,000, significantly more than 1981-85. At Hutchison Bay, there were an estimated 11,000 ducks. As in previous years, large numbers of diving ducks were observed off Atkinson Point at the northwest corner of McKinley Bay, at the south end of the bay, and in the northeast corner near a long spit. Most divers in Hutchison Bay were at the west side. Diving ducks, primarily Oldsquaw and scoter, were the most abundant bird group in the study area. Observed distribution patterns of birds are discussed with reference to habitat preferences. 16 refs., 7 figs., 30 tabs.

Formed as a Crown Corporation in 1952, AECL consists of two main divisions: AECL CANDU, based in Missisauga and Montreal, responsible for the development, design, marketing and project management of CANDU nuclear power projects; and AECL Research, with its head office in Ottawa and laboratories in Chalk River, Ontario and Pinawa, Manitoba, which supports CANDU and performs the research, development, demonstration and marketing required to apply nuclear sciences and their associated technologies. A strategic plan is under development, which will address the issues of market identification, key partnerships, securing the CANDU technology base, export financing and optimum business structure. In 1991/92 operating income was $16.4 million, up from $7.8 million in 1990/91. Good progress was made on goals to revitalize and upgrade AECL employee's skills and productivity. Key goals for AECL CANDU were: launching the Wolsung 2 reactor project in south Korea; closing the timing and product options for Wolsong 3 and 4; securing new business for Cernavoda 1; and attaining an agreement with either Saskatchewan Power Corp. or the New Brunswick Electric Power Commission regarding the timing of their CANDU 3 projects. Some success was achieved in the first three goals; Saskatchewan has chosen not to proceed with its CANDU 3 plant, but negotiations are continuing in New Brunswick. Key goals for AECL Research were: securing an advanced CANDU research and development program outside the CANDU Owners Group; Disposing of remaining non-nuclear technologies by spin-off, licensing or close-out; rationalizing commercial operations to generate increased revenues; and obtaining the Atomic Energy Control Board's approval of the NRU reactor assessment basis document.

Knowledge of the current 'natural' background level is important to 14 C-related studies, especially dose assessments in the vicinity of and distant from nuclear establishments since its value must be subtracted from measured levels to determine local enhancement. Although measurements have been made world-wide to monitor the decline of the background level, from its peak in the early 1960s to the present, there exists a paucity of precise data for UK natural materials. Accordingly this study was carried out to establish an average figure for the 'natural' 14 C level in foodstuffs in 1992 from a survey of materials collected from a wide range of sites over England and Wales, using this single year value, to infill missing years prior to 1992 and to extrapolate from some years afterwards. Results are presented from the survey, and for the derived extrapolation with comparison made with measurements from other laboratories. (Author)

Case Study - Propane School Bus Fleets

Laughlin, M; Burnham, A.

2014-08-31

As part of the U.S. Department of Energy’s (DOE’s) effort to deploy transportation technologies that reduce U.S. dependence on imported petroleum, this study examines five school districts, one in Virginia and four in Texas, successful use of propane school buses. These school districts used school buses equipped with the newly developed liquid propane injection system that improves vehicle performance. Some of the school districts in this study saved nearly 50% on a cost per mile basis for fuel and maintenance relative to diesel. Using Argonne National Laboratory’s Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET) Tool developed for the DOE’s Clean Cities program to help Clean Cities stakeholders estimate petroleum use, greenhouse gas (GHG) emissions, air pollutant emissions and cost of ownership of light-duty and heavy-duty vehicles, the results showed payback period ranges from 3—8 years, recouping the incremental cost of the vehicles and infrastructure. Overall, fuel economy for these propane vehicles is close to that of displaced diesel vehicles, on an energy-equivalent basis. In addition, the 110 propane buses examined demonstrated petroleum displacement, 212,000 diesel gallon equivalents per year, and GHG benefits of 770 tons per year.

This report summarises the results from the environmental survey during 1992 and assesses the effects of radioactive discharges on both local population and the environment. None of the samples taken from possible human food chains in the vicinity of the Lucas Heights Research Laboratories contained radioactivity which could be attributed to the operation of the site. The data presented din this report clearly shows that the environmental impact of operations at LHRL has been very low. The effective dose to residents living in the immediate neighbourhood of the reactor are very difficult to measure directly but calculated dose estimates are far lower than those due to natural background radiation and medical exposures. Discharges of airborne radioactive gases were within authorised limits when averaged over the year. The dose to the most sensitive members of the public from iodine-131 releases, was -2 mSv/year and the calculated dose from released noble gases to the most exposed individuals was less than 0.01 mSv/year. These figures represent less than one per cent of the limits recommended by the National Health and Medical Research Council of Australia. The monthly average liquid effluent discharge to the Water Board Sewer during 1992 was less than 30 per cent of the permitted level for all periods except May which rose to 62 per cent. For tritium, the concentration was less than 2 per cent of the specified limit. 23 refs., 19 tabs., 5 tabs

Subsidence of Surtsey volcano, 1967-1991

Science.gov (United States)

Moore, J.G.; Jakobsson, S.; Holmjarn, J.

1992-01-01

The Surtsey marine volcano was built on the southern insular shelf of Iceland, along the seaward extension of the east volcanic zone, during episodic explosive and effusive activity from 1963 to 1967. A 1600-m-long, east-west line of 42 bench marks was established across the island shortly after volcanic activity stopped. From 1967 to 1991 a series of leveling surveys measured the relative elevation of the original bench marks, as well as additional bench marks installed in 1979, 1982 and 1985. Concurrent measurements were made of water levels in a pit dug on the north coast, in a drill hole, and along the coastline exposed to the open ocean. These surveys indicate that the dominant vertical movement of Surtsey is a general subsidence of about 1.1??0.3 m during the 24-year period of observations. The rate of subsidence decreased from 15-20 cm/year for 1967-1968 to 1-2 cm/year in 1991. Greatest subsidence is centered about the eastern vent area. Through 1970, subsidence was locally greatest where the lava plain is thinnest, adjacent to the flanks of the eastern tephra cone. From 1982 onward, the region closest to the hydrothermal zone, which is best developed in the vicinity of the eastern vent, began showing less subsidence relative to the rest of the surveyed bench marks. The general subsidence of the island probably results from compaction of the volcanic material comprising Surtsey, compaction of the sea-floor sediments underlying the island, and possibly downwarping of the lithosphere due to the laod of Surtsey. The more localized early downwarping near the eastern tephra cone is apparently due to greater compaction of tephra relative to lava. The later diminished local subsidence near the hydrothermal zone is probably due to a minor volume increase caused by hydrous alteration of glassy tephra. However, this volume increase is concentrated at depth beneath the bottom of the 176-m-deep cased drillhole. ?? 1992 Springer-Verlag.

Yukon Energy Corporation annual report for the year ended December 31, 1992

International Nuclear Information System (INIS)

1992-01-01

The Yukon Energy Corporation (YEC) is a subsidiary of a Crown corporation of the territorial government. It generates and distributes 89% of Yukon Territory's electric power. Installed generating capacity in 1992 was 75 MW from hydroelectric plants and 44 MW from diesel generators, for a total of 119 MW. Earnings rose 20% in 1992, from $5.9 million in 1991 to $7.1 million in 1992. The rate of return on equity was 14.8%, up from 12.4% in 1991. This increase in return on equity is due in part to a reduction in the Corporation's equity at December 31, 1992 as part of a restructuring of its capital. The Corporation invested $11.6 million in system improvements during the year. This was a continuation of a program to upgrade YEC facilities. Over $27 million has been spent over the last three years. These improvements were necessary to modernize the system and to improve power quality and reliability. The Corporation completed its 1992 Resource Plan and a hearing was held with the Yukon Utilities Board in October. The plan provided a comprehensive outline of all capital planning activities, including reconnaissance, supply-side development, and demand-side management. The major environmental concern for the Corporation continued to be the management regime at the Aishihik Lake reservoir. A second year of field studies on whitefish recruitment was undertaken by the Yukon Government's Department of Renewable Resources. Financial statements are included. 7 figs

Propane: North American opportunities

International Nuclear Information System (INIS)

Dempsey, C.

1992-01-01

Opportunities for expanding the propane market in North America are discussed. The goal of change should be to enhance client satisfaction and loyalty. The current customer base is largely comprised of pick-up trucks, vans and buses in commercial fleet service, police and similar fleet service and privately owned vehicles. Opportunities for the expansion of propane exist due to: vehicles being kept and lasting longer, allowing a longer pay-back time; exhaust emission standards becoming more stringent; the possible introduction of emission standards for substances currently not controlled; and properly combusted CO 2 emissions that are at least 12% lower than gasoline. The continuing development of engine fuel management systems, application of extensive road/highway experience, matching supply and refuelling infrastructure to consumer demands, application in air quality non-attainment areas, and original equipment manufacturer, government and industry cooperation are discussed. 8 figs

Report on the biological monitoring program at Paducah Gaseous Diffusion Plant December 1990 to November 1992

Kszos, L.A. [ed.

1994-03-01

On September 23, 1987, the Commonwealth of Kentucky Natural Resources and Environmental Protection Cabinet issued an Agreed Order that required the development of a Biological Monitoring Program (BMP) for the Paducah Gaseous Diffusion Plant (PGDP). Beginning in fall 1991, the Environmental Sciences Division (ESD) at Oak Ridge National Lab (ORNL) added data collection and report preparation to its responsibilities for the PGDP BMP. The BMP has been continued because it has proven to be extremely valuable in identifying those effluents with the potential for adversely affecting instream fauna, assessing the ecological health of receiving streams, guiding plans for remediation, and protecting human health. In September 1992, a renewed permit was issued which requires toxicity monitoring of continuous and intermittent outfalls on a quarterly basis. The BMP for PGDP consists of three major tasks: (1) effluent and ambient toxicity monitoring, (2) bioaccumulation studies, and (3) ecological surveys of stream communities. This report includes ESD/ORNL activities occurring from December 1990 to November 1992.

This status report summarizes the activities and accomplishments of the Los Alamos Yucca Mountain Site Characterization Project's quality assurance program for calendar year 1992. The report includes major sections on Program Activities and Trend Analysis. Program Activities are discussed periodically at quality meetings. The most significant issue addressed in 1992 has been the timely revision of quality administrative procedures. The procedure revision process was streamlined from 55 steps to 7. The number of forms in procedures was reduced by 38%, and the text reduced by 29%. This allowed revision in 1992 of almost half of all implementing procedures. The time necessary to complete the revision process (for a procedure) was reduced from 11 months to 3 months. Other accomplishments include the relaxation of unnecessarily strict training requirements, requiring quality assurance reviews only from affected organizations, and in general simplifying work processes. All members of the YMP received training to the new Orientation class Eleven other training classed were held. Investigators submitted 971 records to the Project and only 37 were rejected. The software program has 115 programs approved for quality-affecting work. The Project Office conducted 3 audits and 1 survey of Los Alamos activities. We conducted 14 audits and 4 surveys. Eight corrective action reports were closed, leaving only one open. Internally, 22 deficiencies were recognized. This is a decrease from 65 in 1991. Since each deficiency requires about 2 man weeks to resolve, the savings are significant. Problems with writing acceptable deficiency reports have essentially disappeared. Trend reports for 1992 were examined and are summarized herein. Three adverse trends have been closed; one remaining adverse trend will be closed when the affected procedures are revised. The number of deficiencies issued to Los Alamos compared to other participants is minimal

Results of dust precipitation and airborne dust measurements in the Rhineland Brown Coal Mining Area in 1991 and 1992

International Nuclear Information System (INIS)

Respondek, A.; Stein, W.

1994-01-01

In the Rhineland brown coal mining area the immission value of IW 1 = 0.35 g/(m 2 xd), as stipulated in the Technical Specifications for Air Pollution Control, was not reached anywhere in the entire above-mentioned measured area in 1991. The maximum monthly pollution load, i.e. I 2 = 0.52 g/(m 2 xd), was less than the immission value IW 2 = 0.65 g/(m 2 xd). In the measured areas under review, Rheinschiene South and Rheinschiene Centre, the values for airborne dust immission I 1 in 1991 were also less than 50% of the IW 1 value of 0.15 mg/m 3 . In view of these results and also - the measurements carried out by the LIS (State Pollution Control Authority) over many years in the townships of Kerpen, Frechen-Bachem, Huerth-Hermuelheim, Horrem, Frechen and Pulheim. - A special measurement carried out by the LIS in the Erft district and in the south of the Neuss district in 1983, and - the measurements carried out in accordance with the specifications for the licensing and development plan procedures, as well as - the results of the special measurement programme carried out in the community of Elsdorf in 1988 and 1989, there is no reason to fear that harmful effects on the environment will be caused by brown coal opencast mines and coal processing plants as a result of airborne dust. The dust precipitation measurements carried out at the request of the Cologne Mines Inspectorate revealed that in 1992 none of the values measured exceeded the IW 1 value. The highest measured I 1 value was 0.21 g/(m 2 xd), i.e. 60% of the IW 1 value. The average pollution load was 0.13 g/(m 2 xd), i.e. 37%. (orig./MSK) [de

This report evaluates evapotranspiration for six sites in Benton, Spokane, and Yakima Counties, Washington. Three sites were located on the Arid Lands Ecology Reserve in Benton County: one at a full-canopy grassland in Snively Basin (Snively Basin site), one at a sparse-canopy grassland adjacent to two weighing lysimeters (grass lysimeter site), and one at a sagebrush grassland adjacent to two weighing lysimeters (sage lysimeter site). Two sites were located on the Turnbull National Wildlife Refuge in Spokane County: one at a full-canopy grassland in a meadow (Turnbull meadow site), the other a full-canopy grassland near a marsh (Turnbull marsh site). The last site was located in a sagebrush grassland in the Black Rock Valley in Yakima County (Black Rock Valley site). The periods of study at the six sites varied, ranging from 5 months at the Black Rock Valley site to more than 2 years at the Snively Basin, grass lysimeter, and sage lysimeter sites. The periods of study were May 1990 to September 1992 for the Snively Basin, grass lysimeter, and sage lysimeter sites; May 1991 to September 1992 for the Turnbull meadow site; May 1991 to April 1992 for the Turnbull marsh site; and March to September 1992 for the Black Rock Valley site. Evapotranspiration and energy-budget fluxes were estimated for the Snively Basin site, the Turnbull meadow site, and the Black Rock Valley site using the Bowen-ratio and Penman-Monteith methods. Daily evapotranspiration for the Snively Basin site was also estimated using a deep-percolation model for the Columbia Basin. The Bowen-ratio method and weighing lysimeters were used at the grass and sage lysimeter sites. The Penman-Monteith method was used at the Turnbull marsh site. Daily evapotranspiration at the sites ranged from under 0.2 millimeter during very dry or cold periods to over 4\\x11millimeters after heavy rainfall or during periods of peak transpiration. At all sites, peak evapotranspiration occurred in spring, coinciding with

Simulation studies of steam-propane injection for the Hamaca heavy oil field

Laboratory experiments have been conducted at Texas A and M University to examine the use of steam additives such as propane, methane and nitrogen to improve the production of heavy oils and increase steam recovery efficiency. In particular, the use of steam-propane injection for heavy Hamaca crude oil with API gravity of 9.3 and viscosity of 25,000 cp at 50 degrees C was examined. Experimental runs involved the injection of steam or propane into injection cells at a constant rate, temperature and cell outlet pressure. The experimental results suggest that the use of steam-propane injection may translate to reduction of fuel costs for field injections. Initially, propane-steam injection resulted in a two-month oil production acceleration compared to pure steam injection. A significant gain in discounted revenue and savings in steam injection costs could be realized. The study also showed the oil product rate peak with steam-propane injection was much higher than that with pure steam injection. The oil production acceleration increases with increasing propane content. Oil recovery at the end of a five-year forecast period increases by 6.7 per cent of original oil in place (OOIP) compared to 2.3 per cent OOIP with pure steam injection. 12 refs., 6 tabs., 28 figs.

Conversion of diesel engines to dual fuel (propane/diesel) operations

Energy Technology Data Exchange (ETDEWEB)

Pepper, S W; DeMaere, D A

1984-02-01

A device to convert a diesel engine to dual fuel (propane/diesel) operation was developed and evaluated. Preliminary experimentation has indicated that as much as 30% of the diesel fuel consumed in diesel engines could be displaced with propane, accompanied by an improvement in fuel efficiency, engine maintenance and an overall reduction in emission levels. Dual fuel operations in both transportation and stationary applications would then project a saving of ca 90,000 barrels of diesel fuel per day by the year 1990. A turbo-charged 250 hp diesel engine was directly coupled to a dynamometer under laboratory conditions, and operated at speeds between 500 and 2500 rpm and at various torque levels. At each rpm/torque point the engine first operated on diesel fuel alone, and then increasing quantities of propane were induced into the air intake until detonation occured. Results indicate that the proportion of propane that can be safely induced into a diesel engine varies considerably with rpm and torque so that a sophisticated metering system would be required to maximize diesel oil displacement by propane. Conversion is not cost effective at 1983 price levels.

School Districts Move to the Head of the Class with Propane

Energy Technology Data Exchange (ETDEWEB)

2016-01-01

Propane has been a proven fuel for buses for decades. For the first time in 2007, Blue Bird rolled out a propane school bus using direct liquid injection, which was later followed by Thomas Built Buses and Navistar. Because this new technology is much more reliable than previous designs, it is essentially reintroducing propane buses to many school districts. During this same time period, vehicle emissions standards have tightened. To meet them, diesel engine manufacturers have added diesel particulate filters (DPF) and, more recently, selective catalytic reduction (SCR) systems. As an alternative to diesel buses with these systems, many school districts have looked to other affordable, clean alternatives, and they've found that propane fits the bill.

This study examines census data on women's work status during 1981 and 1991 in Kerala state in India. During 1981 and 1991, Kerala had a stable female work participation rate (FWPR), which placed Kerala 19th out of 30 states and Union territories. However, Kerala's FWPR declined in size and in the ratio to the male work participation rate during 1951-81. The work participation rate in Kerala was 15.85 for women and 47.58 for men in 1991 and 16.61 for women and 44.89 for men in 1981, which was under the national average. Fertility declined from 3.7 during 1970-75 to 1.7 in 1992. Life expectancy at birth was 74.7 years for women and 68.8 years for men, which is higher than the national average. The proportion of persons aged 15-59 years increased. Several explanations are offered to explain the low FWPR. Women increased in the number of enrollments in higher education. The increase for women was 50% compared to only 24% for men. The number of unemployed women aged 15-34 years rose during 1961-81. A 1987-88 unemployment survey revealed that over 10% of the unemployed in India lived in Kerala state, which had only 3.4% of total Indian population. A 1987 migration survey indicated that 300,929 workers from Kerala migrated to the Middle East, of which 92.5% were men. 31.43% of Kerala's population in 1991 were workers. The increase in the proportion of workers during 1981-91 was due primarily to the increase in male workers. The number of main workers increased over the decade for men and women, although only marginally for women. Marginal workers declined for both genders. Work participation rates of main and marginal workers increased for men and declined for women. Urban employment for women increased. Two districts had very low FWPRs. 48.78% of the female work force worked as cultivators and agricultural laborers. Growth occurred in urban and tertiary activities.

Propane is one of the primary components of emissions from natural gas extraction and processing activities. In addition to being an air pollutant, its ratio to other hydrocarbons such as methane and ethane can serve as a "fingerprint" of a particular facility or process, aiding in identifying emission sources. Quantifying propane has typically required laboratory analysis of flask samples, resulting in low temporal resolution and making plume-based measurements infeasible. Here we demonstrate fast (1-second), high precision (infrared spectroscopy at 2967 wavenumbers. In addition, we explore the impact of nearby water and ethane absorption lines on the accuracy and precision of the propane measurement. Finally, we discuss development of a dual-laser instrument capable of simultaneous measurements of methane, ethane, and propane (the C1-C3 compounds), all within a small spatial package that can be easily deployed aboard a mobile platform.

1997-01-01

The following is a summary report of the New Hampshire Governor's Office of Energy and Community Services (ECS) participation in the State Heating Oil and Propane Program (SHOPP) for the 1996-97 heating season. SHOPP is a cooperative effort, linking energy offices in East Coast and Midwest states, with the Department of Energy (DOE), Energy Information Administration (EIA) for the purpose of collecting retail price data for heating oil and propane. The program funded by the participating state with a matching grant from DOE. SHOPP was initiated in response to congressional inquires into supply difficulties and price spikes of heating oil and propane associated with the winter of 1989/90. This is important to New Hampshire because heating oil controls over 55% of the residential heating market statewide. Propane controls 10% of the heating market statewide and is widely used in rural areas where Natural GAs is not available. Lower installation cost, convenience, lower operating costs compared to electricity and its perception as a clean heating fuel has increased the popularity of propane in New Hampshire and should continue to do so in the future. Any disruption in supply of these heating fuels to New Hampshire could cause prices to skyrocket and leave many residents in the cold

Activities related to revitalisation of the RA reactor stared in 1986, were continued in 1991. A number of interventions on the reactor components were finished that are supposed to enable continuous and reliable operation. The last, and at the same time largest action, related to exchange of complete reactor instrumentation is underway, but it is behind the schedule in 1991 because the delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Only 56% of the instrumentation was delivered until September 1991. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA. In 1991 most of the existing RA reactor instrumentation was dismantled, only the part needed for basic measurements when reactor is not operated, was maintained. Construction of some support elements is almost finished by the local staff. The Institute has undertaken this activity in order to speed up the ending of the project. If all the planned instrumentation would not arrive until the end of March 1992, it would not be possible to start the RA reactor testing operation in the first part of 1993, as previously planned. In 1991, 53 staff members took part in the activities during 1991, which is considered sufficient for maintenance and repair conditions. Research reactor RA Annual report for year 1991 is divided into two main parts to cover: (1) operation and maintenance and (2) activities related to radiation protection [sr

This paper deals with self-ignition of catalytic microburners from ambient cold-start conditions. First, reaction kinetics for hydrogen combustion is validated with experimental results from the literature, followed by validation of a simplified pseudo-2D microburner model. The model is then used to study the self-ignition behavior of lean hydrogen/air mixtures in a Platinum-catalyzed microburner. Hydrogen combustion on Pt is a very fast reaction. During cold start ignition, hydrogen conversion reaches 100% within the first few seconds and the reactor dynamics are governed by the ''thermal inertia'' of the microburner wall structure. The self-ignition property of hydrogen can be used to provide the energy required for propane ignition. Two different modes of hydrogen-assisted propane ignition are considered: co-feed mode, where the microburner inlet consists of premixed hydrogen/propane/air mixtures; and sequential feed mode, where the inlet feed is switched from hydrogen/air to propane/air mixtures after the microburner reaches propane ignition temperature. We show that hydrogen-assisted ignition is equivalent to selectively preheating the inlet section of the microburner. The time to reach steady state is lower at higher equivalence ratio, lower wall thermal conductivity, and higher inlet velocity for both the ignition modes. The ignition times and propane emissions are compared. Although the sequential feed mode requires slightly higher amount of hydrogen, the propane emissions are at least an order of magnitude lower than the other ignition modes. (author)

Annual report 1991

1992-01-01

During 1991 Ontario Hydro's activities reflected a company in transition marked by changing customer needs, new social demands and global economic pressures. The nuclear system performed below expectations, although performance improved over 1990. Technical problems prevented the utility from bringing Darlington NGS unit 1 into service. Ontario Hydro has committed about $4 billion to extend the lives of fossil and hydroelectric stations and restore nuclear performance. In September Ontario Hydro's management structure was reorganized again. Policy, planning and strategic efforts were put under the direction of the Chair. All operating functions were to report directly to the President. New Board committees were formed to guide environmental activities and promote a better understanding of aboriginal and northern affairs. The unfavourable economic and operating conditions of 1991 affected financial performance. An 11.8% rate increase was announced for 1992. Electricity demand increased by 1.3%over 1990 to 139.1 million megawatt hours. Major capital additions have been deferred by at least seven years. Uranium contracts were canceled with Rio Algom and Denison Mines. Administrative and support budgets were cut, and executive salaries frozen. A number of quality improvement programs have been implemented with the cooperation of labour groups, reducing the amount of time needed for the retubing of the Pickering-4 reactor. (L.L.)

The results of the various monitoring programs for 1991 indicate that most radioactivity from the Idaho National Engineering Laboratory (INEL) operations could not be distinguished from worldwide fallout and natural radioactivity in the region surrounding the INEL Site. Although some radioactive materials were discharged during Site operations, concentrations and doses to the surrounding population were of no health consequence and were far less than State of Idaho and Federal health protection guidelines. The first section of the report summarizes Calendar Year 1991 and January 1 through June 1, 1992, INEL activities related to compliance with environmental regulations and laws. The major portion of the report summarizes results of the RESL environmental surveillance program, which includes the collection of foodstuffs at the INEL boundary and distant offsite locations, and the collection of air and water samples at onsite locations and offsite boundary and distant locations. The report also compares and evaluates the sample results to appropriate federal regulations and standards and discusses implications, if any. The US Geological Survey (USGS) groundwater monitoring program is briefly summarized and data from USGS reports are included in tables and maps showing the spread of contaminants. Effluent monitoring and nonradiological drinking water monitoring performed by INEL contractors are discussed briefly and data are summarized in tables

1992-12-31

During fiscal year 1992, the reserves generated $473 million in revenues, a $181 million decrease from the fiscal year 1991 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $200 million, resulting in net cash flow of $273 million, compared with $454 million in fiscal year 1991. From 1976 through fiscal year 1992, the Naval Petroleum and Oil Shale Reserves generated more than $15 billion in revenues and a net operating income after costs of $12.5 billion. In fiscal year 1992, production at the Naval Petroleum Reserves at maximum efficient rates yielded 26 million barrels of crude oil, 119 billion cubic feet of natural gas, and 164 million gallons of natural gas liquids. From April to November 1992, senior managers from the Naval Petroleum and Oil Shale Reserves held a series of three workshops in Boulder, Colorado, in order to build a comprehensive Strategic Plan as required by Secretary of Energy Notice 25A-91. Other highlights are presented for the following: Naval Petroleum Reserve No. 1--production achievements, crude oil shipments to the strategic petroleum reserve, horizontal drilling, shallow oil zone gas injection project, environment and safety, and vanpool program; Naval Petroleum Reserve No. 2--new management and operating contractor and exploration drilling; Naval Petroleum Reserve No. 3--steamflood; Naval Oil Shale Reserves--protection program; and Tiger Team environmental assessment of the Naval Petroleum and Oil Shale Reserves in Colorado, Utah, and Wyoming.

Assessment of the risk of transporting propane by truck and train

Energy Technology Data Exchange (ETDEWEB)

Geffen, C.A.

1980-03-01

The risk of shipping propane is discussed and the risk assessment methodology is summarized. The risk assessment model has been constructed as a series of separate analysis steps to allow the risk to be readily reevaluated as additional data becomes available or as postulated system characteristics change. The transportation system and accident environment, the responses of the shipping system to forces in transportation accidents, and release sequences are evaluated to determine both the likelihood and possible consequences of a release. Supportive data and analyses are given in the appendices. The risk assessment results are related to the year 1985 to allow a comparison with other reports in this series. Based on the information presented, accidents involving tank truck shipments of propane will be expected to occur at a rate of 320 every year; accidents involving bobtails would be expected at a rate of 250 every year. Train accidents involving propane shipments would be expected to occur at a rate of about 60 every year. A release of any amount of material from propane trucks, under both normal transportation and transport accident conditions, is to be expected at a rate of about 110 per year. Releases from propane rail tank cars would occur about 40 times a year. However, only those releases that occur during a transportation accident or involve a major tank defect will include sufficient propane to present the potential for danger to the public. These significant releases can be expected at the lower rate of about fourteen events per year for truck transport and about one event every two years for rail tank car transport. The estimated number of public fatalities resulting from these significant releases in 1985 is fifteen. About eleven fatalities per year result from tank truck operation, and approximately half a death per year stems from the movement of propane in rail tank cars.

An aerial radiological survey of Par Pond and associated drainage pathways of the Savannah River Site, Aiken, South Carolina

International Nuclear Information System (INIS)

1992-12-01

The first of a three-phase effort to radiologically monitor the lowering of Par Pond and associated drainage pathways was conducted over three areas of the Savannah River Site (SRS). The areas surveyed during this first phase included Par Pond, the Savannah River swamp from Steel Creek to Little Hell Landing, and Lower Three Runs Creek from the mouth of Lower Three Runs to the Highway 301 Bridge. The first phase was conducted to coincide with the lowering of the water level of Par Pond to an elevation of 190 feet above sea level. Additional surveys were conducted when the water level was at an elevation of 180 feet and prior to refill. The first survey began August 19, 1991, and was completed September 11, 1991. The second survey was conducted in October/November, 1991, during the SRS site-wide survey, and the third survey was conducted in August/September, 1992. Only the Par Pond area itself was surveyed during the third and final phase. The radiation detected over the Creek Plantation portion of the Savannah River swamp and Lower Three Runs areas during the August 1991 survey was consistent with the spatial distribution, quantity, and kinds of radionuclides detected during the 1983 and 1986 surveys. No migration of man-made gamma emitting materials was detected when compared to the prior surveys. The major differences occurred along the Par Pond shoreline where lowered water levels exposed the contaminated pond bed. The activity in the pond bed was attenuated by the water cover prior to the start of the lowering of Par Pond in June 1991. The data collected during each survey were processed in the field and were presented to SRS. A comparison report is being generated after the completion of each survey. A final report will be generated for the three surveys and will include a quantitative comparison of the three surveys in the Par Pond area only

This report outlines long-term planning and monitoring activities that occurred in 1991 and 1992 in the Stanley Basin Lakes of the upper Salmon River, Idaho for the purpose of sockeye salmon nerka) recovery. Limnological monitoring and experimental sampling protocol, designed to establish a limnological baseline and to evaluate sockeye salmon production capability of the lakes, are presented. Also presented are recommended passage improvements for current fish passage barriers/impediments on migratory routes to the lakes. We initiated O. nerka population evaluations for Redfish and Alturas lakes; this included population estimates of emerging kokanee fry entering each lake in the spring and adult kokanee spawning surveys in tributary streams during the fall. Gill net evaluations of Alturas, Pettit, and Stanley lakes were done in September, 1992 to assess the relative abundance of fish species among the Stanley Basin lakes. Fish population data will be used to predict sockeye salmon production potential within a lake, as well as a baseline to monitor long-term fish community changes as a result of sockeye salmon recovery activities. Also included is a paper that reviews sockeye salmon enhancement activities in British Columbia and Alaska and recommends strategies for the release of age-0 sockeye salmon that will be produced from the current captive broodstock.

1994-12-01

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of a survey conducted in June 1991 at the Mill Creek tributary crossing, Jefferson County, New York. One pipeline had been installed through the wetland in 1966, and another was scheduled to be installed later in 1991. Data were collected along the existing pipeline ROW and also along the planned ROW for use as baseline data in future studies. Four separate communities were surveyed. A scrub-shrub wetland and a forested wetland were sampled along the existing ROW where the planned pipeline was to be installed. A mixed vegetation community was sampled along the existing ROW, west of where the planned pipeline would joint the ROW. A marsh community was sampled along the route of the planned pipeline. All plant species found on the ROW of the scrub-shrub community were also present in the adjacent natural areas. The vegetation on the ROW of the forested wetland community also consisted mostly of species found in the adjacent natural areas. In the mixed vegetation community, a small drainage channel present on the ROW, possibly resulting from the pipeline construction, provided habitat for a number of obligate species not found in other areas of this community. Differences noted among different areas of this community were also attributed to slight variations in elevation.

The Coal Kind Committee in this fiscal year was held on September 28, 1992 (1st) and on March 4, 1993 (second), and report/discussion were made about the performance test in Chinese coal liquefaction, survey of coal kind selection, development of handling technology, etc. As to the performance test in Chinese coal liquefaction, there were the data very different in quality among the data, and it was pointed out that it was necessary to make a close re-examination of sites for sample collection and sampling methods. Relating to the survey of coal kind selection, the following were pointed out: The inertinite value in the maceral analysis was not necessarily in agreement with the reactivity; The inertinite was dependent largely on temperature for the reaction; It was necessary to make parameters based on the chemical structure. As to the development of the coal utilization hydrogen production technology, the paper reported the experimental survey of coal pretreatment, development of new deheterocyclicity and deashing technologies, experimental survey of coal handling, etc. (NEDO)

State heating oil and propane program (SHOPP). Final report, 1995/96 - Kentucky

International Nuclear Information System (INIS)

1996-01-01

Kentucky's second year of participation in SHOPP was successful. The survey started with a sample group of fifty (50), with forty-nine (49) actually participating. Survey participants were contacted by telephone each reporting period from October to March. Some companies reported supply problems, due to allocation, resulting in having to go greater distances to obtain the propane they needed and some reported only being supplied a portion of what they wanted. Most companies did not experience allocation or supply problems. The winter was colder and longer than usual. Wholesale prices did increase. However, most suppliers tried to keep prices down. There were a few reports of problems delivering to customers due to an abnormal amount of snow in eastern Kentucky

Stoker, S.W.; Neff, J.M.; Schroeder, T.R.; McCormick, D.M.

1993-01-01

This report is based primarily on survey results from Prince William Sound, where most of the heavy shoreline oiling occurred. Although not strictly quantitative, the shoreline surveys provide an unprecedented, broad base of professional observations covering the entire spill-affected area from 1989 through 1992 by which to evaluate spill impacts and recovery. Shoreline surveys documented that the extent of shoreline oiling declined substantially from 1989 to 1992. In 1989, oil was found on about 16 percent of the 3,000 miles of shoreline in Prince William Sound; by the spring of 1991, oil was found on only about 2 percent of the shoreline; and by May of 1992, on only 0.2 percent. In all years, most of this oil was located in the biologically least productive upper intertidal and supratidal zones. In both 1991 and 1992, small, isolated pockets of subsurface oil were found on some boulder/cobble beaches. Most of these deposits were also located in the upper intertidal and were usually buried beneath clean sediments. In almost all cases, the condition of intertidal biological communities improved correspondingly from 1989 to 1992. By the spring of 1991, recovery appeared to be well under way on virtually all previously oiled shores, with species composition, abundance, and diversity levels usually comparable to those of nearby shores that were not oiled in 1989. Recruitment of intertidal plants and animals was observed as early as the summer of 1989, and increasingly through 1991 and 1992. Recruitment was evident even in areas with remnant deposits of surface and subsurface oil, indicating that toxicity levels of the oil had declined substantially and that, in most cases, the residual oil no longer interfered with biological recovery. Observations of birds and marine mammals on or near shorelines surveyed during 1991 and 1992 confirmed that species present before the spill were still present and were feeding and reproducing in areas affected by oil in 1989

Låg, M; Omichinski, J G; Dybing, E; Nelson, S D; Søderlund, E J

1994-10-01

A series of halogenated propanes and propenes were studied for mutagenic effects in Salmonella typhimurium TA100 in the absence or presence of NADPH plus liver microsomes from phenobarbital-induced rats as an exogenous metabolism system. The cytotoxic and mutagenic effects of the halogenated propane 1,2-dibromo-3-chloropropane (DBCP) has previously been studied in our laboratories. These studies showed that metabolic activation of DBCP was required to exert its detrimental effects. All of the trihalogenated propane analogues were mutagenic when the microsomal activation system was included. The highest mutagenic activity was obtained with 1,2,3-tribromopropane, with approximately 50-fold higher activity than the least mutagenic trihalogenated propane, 1,2,3-trichloropropane. The order of mutagenicity was as follows: 1,2,3-tribromopropane > or = 1,2-dibromo- 3-chloropropane > 1,3-dibromo-2-chloropropane > or = 1,3-dichloro-2-bromopropane > 1-bromo-2,3-dichloropropane > 1,2,3-trichloropropane. Compared to DBCP, the dihalogenated propanes were substantially less mutagenic. Only 1,2-dibromopropane was mutagenic and its mutagenic potential was approximately 1/30 of that of DBCP. In contrast to DBCP, 1,2-dibromopropane showed similar mutagenic activity with and without the addition of an activation system. The halogenated propenes 2,3-dibromopropene and 2-bromo-3-chloropropene were mutagenic to the bacteria both in the absence and presence of the activation system, whereas 2,3-dichloropropene did not show any mutagenic effect. The large differences in mutagenic potential between the various halogenated propanes and propenes are proposed to be due to the formation of different possible proximate and ultimate mutagenic metabolites resulting from the microsomal metabolism of the various halogenated propanes and propenes, and to differences in the rate of formation of the metabolites. Pathways are proposed for the formation of genotoxic metabolites of di- and trihalogenated

An evaluation of propane as a fuel for testing fire-resistant oil spill containment booms

International Nuclear Information System (INIS)

Walton, W. D.; Twilley, W. H.

1997-01-01

A series of experiments have been conducted to measure and compare the thermal exposure to a fire-resistant boom from liquid hydrocarbon fuel and propane fires. The objective was to test the potential of propane fueled fires as a fire source for testing fire-resistant oil spill containment booms.Thermal exposure from propane fires have been measured with and without waves. Results indicated that although propane diffusion flames on water look like liquid hydrocarbon fuel flames and produce very little smoke, the heat flux at the boom location from propane fires is about 60 per cent of that from liquid hydrocarbon fuel fires. Despite the attractive features in terms of ease of application, control and smoke emissions, it was concluded that the low heat flux would preclude the application of propane as a fuel for evaluating fire resistant containment booms. 2 refs., 7 figs

Experimental study and modelization of a propane storage tank depressurization

International Nuclear Information System (INIS)

Veneau, Tania

1995-01-01

The risks associated with the fast depressurization of propane storage tanks reveals the importance of the 'source term' determination. This term is directly linked, among others, to the characteristics of the jet developed downstream of the breach. The first aim of this work was to provide an original data bank concerning drop velocity and diameter distributions in a propane jet. For this purpose, a phase Doppler anemometer bas been implemented on an experimental set-up. Propane blowdowns have been performed with different breach sizes and several initial pressures in the storage tank. Drop diameter and velocity distributions have been investigated at different locations in the jet zone. These measurements exhibited the fragmentation and vaporisation trends in the jet. The second aim of this work concerned the 'source term'. lt required to study the coupling between the fluid behaviour inside the tank and the flow through the breach. This model took into account the phase exchange when flashing occurred in the tank. The flow at the breach was described with an homogeneous relaxation model. This coupled modelization has been successfully and exhaustively validated. lt originality lies on the application to propane flows. (author) [fr

Effective separation of propylene/propane binary mixtures by ZIF-8 membranes

KAUST Repository

Pan, Yichang

2012-02-01

The separation of propylene/propane mixtures is one of the most important but challenging processes in the petrochemical industry. A novel zeolitic imidazole framework (ZIF-8) membrane prepared by a facile hydrothermal seeded growth method showed excellent separation performances for a wide range of propylene/propane mixtures. The membrane showed a permeability of propylene up to 200. barrers and a propylene to propane separation factor up to 50 at optimal separation conditions, well surpassing the "upper-bound trade-off" lines of existing polymer and carbon membranes. The experimental data also showed that the membranes had excellent reproducibility, long-term stability and thermal stability. © 2011 Elsevier B.V.

Potassium effects on kinetics of propane oxydehydrogenation on vanadia-titania catalyst

International Nuclear Information System (INIS)

Grabowski, R.; Samson, K.

2003-01-01

Oxidative dehydrogenation of propane (ODH) over V 2 O 5 /TiO 2 and V 2 O 5 /TiO 2 doped with K was carried out by measuring conversions and selectiveness for various feed compositions, contact times and temperatures. The results obtained for both catalysts were interpreted on the basis of the mechanism, in which propene is formed through Eley-Rideal sequence of steps, i.e. without participation of the adsorbed propane species. Kinetic constants (activation energies, pre-exponential factors) for the model of ODH reaction of propane on these catalysts, obtained on the basis of steady-state results, are given. Addition of K to vanadia-titania catalysts leads to decrease of total combustion of propane and consecutive combustion of propene. It has been found that the direct propane total oxidation is 5 - 9 times lower than that of the consecutive propene oxidation and is almost temperature independent for potassium doped catalyst, whereas it quickly decreases with temperature for a non-doped catalyst. Secondly, the addition of K to a vanadia-titania catalyst decreases the activation energies for propene formation (k 1 ), parallel formation of CO x (k 3 ) and reoxidation of the catalyst (k os ). Potassium exhibits a stronger inhibitory effect on the secondary propene combustion, what reflects the lower activity of V 5+ cations modified by the strongly basic alkali oxide species. (author)

The Savannah River Site`s Groundwater Monitoring Program: Second quarter 1992

Rogers, C.D. [Westinghouse Savannah River Co., Aiken, SC (United States)

1992-10-07

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site`s (SRS) Groundwater Monitoring Program. During second quarter 1992, EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of criteria to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identification. Since 1991, the flagging criteria have been based on the federal Environmental Protection Agency (EPA) drinking water standards and on method detection limits. A detailed explanation of the current flagging criteria is presented in the Flagging Criteria section of this document. Analytical results from second quarter 1992 are listed in this report.

Selective bio-oxidation of propane to acetone using methane-oxidizing Methylomonas sp. DH-1.

Hur, Dong Hoon; Nguyen, Thu Thi; Kim, Donghyuk; Lee, Eun Yeol

Propane is the major component of liquefied petroleum gas (LPG). Nowadays, the use of LPG is decreasing, and thus utilization of propane as a chemical feedstock is in need of development. An efficient biological conversion of propane to acetone using a methanotrophic whole cell as the biocatalyst was proposed and investigated. A bio-oxidation pathway of propane to acetone in Methylomonas sp. DH-1 was analyzed by gene expression profiling via RNA sequencing. Propane was oxidized to 2-propanol by particulate methane monooxygenase and subsequently to acetone by methanol dehydrogenases. Methylomonas sp. DH-1 was deficient in acetone-converting enzymes and thus accumulated acetone in the absence of any enzyme inhibition. The maximum accumulation, average productivity and specific productivity of acetone were 16.62 mM, 0.678 mM/h and 0.141 mmol/g cell/h, respectively, under the optimized conditions. Our study demonstrates a novel method for the bioconversion of propane to acetone using methanotrophs under mild reaction condition.

To examine trends in stunting and overweight in Peruvian children, using 2006 WHO Multicentre Growth Reference Study criteria. Trend analyses using nationally representative cross-sectional surveys from Demographic and Health Surveys (1991-2011). We performed logistic regression analyses of stunting and overweight trends in sociodemographic groups (sex, age, urban-rural residence, region, maternal education and household wealth), adjusted for sampling design effects (strata, clusters and sampling weights). Peru. Children aged 0-59 months surveyed in 1991-92 (n 7999), 1996 (n 14 877), 2000 (n 11 754), 2007-08 (n 8232) and 2011 (n 8186). Child stunting declined (F(1, 5149) = 174·8, P ≤ 0·00) and child overweight was stable in the period 1991-2011 (F(1, 5147) = 0·4, P ≤ 0·54). Over the study period, levels of stunting were highest in rural compared with urban areas, the Andean and Amazon regions compared with the Coast, among children of low-educated mothers and among children living in households in the poorest wealth quintile. The trend in overweight rose among males in coastal areas (F(1, 2250) = 4·779, P ≤ 0·029) and among males in the richest wealth quintile (F(1, 1730) = 5·458, P ≤ 0·020). The 2011 levels of stunting and overweight were eight times and three and a half times higher, respectively, than the expected levels from the 2006 WHO growth standards. The trend over the study period in stunting declined in most sociodemographic subgroups. The trend in overweight was stable in most sociodemographic subgroups.

Full Text Available This study presents a 2D-axisymmetric computational fluid dynamic (CFD model to investigate the performance Pd membrane reactor (MR during propane dehydrogenation process for hydrogen production. The proposed CFD model provided the local information of temperature and component concentration for the driving force analysis. After investigation of mesh independency of CFD model, the validation of CFD model results was carried out by other modeling data and a good agreement between CFD model results and theoretical data was achieved. Indeed, in the present model, a tubular reactor with length of 150 mm was considered, in which the Pt-Sn-K/Al2O3 as catalyst were filled in reaction zone. Hence, the effects of the important operating parameter (reaction temperature on the performances of membrane reactor (MR were studied in terms of propane conversion and hydrogen yield. The CFD results showed that the suggested MR system during propane dehydrogenation reaction presents higher performance with respect to once obtained in the conventional reactor (CR. In particular, by applying Pd membrane, was found that propane conversion can be increased from 41% to 49%. Moreover, the highest value of propane conversion (X = 91% was reached in case of Pd-Ag MR. It was also established that the feed flow rate of the MR is to be the one of the most important factors defining efficiency of the propane dehydrogenation process.

Giant Syncrude oilsand plant a prodigious user of propane

International Nuclear Information System (INIS)

Anon

2001-01-01

Approximately 13 per cent of Canada's petroleum requirements are met by the huge Syncrude plant in northern Alberta, the largest producer of crude from oilsands in the world and the largest source producer in Canada. The plant is located just north of Fort McMurray northeast of Edmonton. The operation of the plant relies in a very large part on the use of propane. Scattered on the site are 130 propane tanks. The pumphouse is equipped with four 1,000-gallon tanks, and the mobile Sundog heaters in the mine site are equipped with a number of 420-pound tanks that supply the required power. The yearly maintenance program requires the use of an additional 80 to 90 tanks that are brought on the site for that purpose. All told, two million litres of propane are used yearly at the plant. Heating the facilities and equipment is the main use for the propane. For example, heating the draglines (25-storey high and a bucket as large as a two-car garage) that scoop the oilsand and transport it for processing necessitate the use of several 20-pound and 40-pound propane-powered tiger torches. However, large trucks and shovels, part of an innovative transport system called hydro transport, will soon replace the draglines. This new method eliminates the need for draglines, bucket wheels, conveyer systems and conditioning tumblers by mixing the oilsand with water for transportation by pipeline. The first step of the extraction process, the conditioning, occurs in the pipeline. Upon reaching the extraction plant, the mixture is directed into the separation vessels. Without an increase in energy usage or carbon dioxide emissions, Syncrude is able to increase its extraction activity by switching to hydro transport. The requirement for propane is still present as the bottom of the slurry has to be heated for transport. Some basic facts concerning Syncrude and its operation were presented, as well as an overview of the oilsand business, its history and its financial results. For example

Events in the Canadian nuclear industry from June 1991 to June 1992 are highlighted, with emphasis on the role of the Canadian Nuclear Association (CNA) and its committees. Korea purchased a second CANDU 6 at the end of 1990, with the prospect (since realized) of two further sales. Canada agreed to assist Romania in financing the completion of Cernovoda 1, which is expected to come on stream in 1994, the first of four units. The Saskatchewan government decided not to ratify a memorandum of understanding with AECL on a study of the CANDU 3 reactor in that province (but an agreement has since been reached). At the time of writing, the CNA was hoping to be allowed to make a submission to the Ontario Hearing Board in favour of the nuclear option

World oil flow slips in 1991 amid Mideast, U.S.S.R. woes

1992-01-01

World crude oil production slipped 0.9% in 1991 to average 59,964 million b/d. This paper reports that production declines related to war damage in Kuwait, United Nations sanctions on exports from Iraq, and oil sector woes in the crumbling U.S.S.R. were almost offset by higher production from other members of the Organization of Petroleum Exporting Countries. OPEC crude production rose 0.6% in 1991 to average 23.425 million b/d, and non-OPEC output fell 1.9% to average 36.539 million b/d in 1991. Excluding the U.S.S.R., non-OPEC production moved up 1.5% to average 26.239 million b/d. World demand inched up about 200,000 b/d, estimates International Energy Agency, and IEA data show about 300,000 b/d was added to stocks in 1991. World crude prices started 1991 at their highest level, then fell off to average $17.82/bbl, down 16.5% from 1990 levels. Meantime, a slight increase in demand is predicted for 1992, and price stability again hinges on OPEC's ability to limit production

Bio-Oil Separation and Stabilization by Near-Critical Propane Fractionation

Energy Technology Data Exchange (ETDEWEB)

Ginosar, Daniel M.; Petkovic, Lucia M.; Agblevor, Foster A.

2016-08-01

Bio-oils produced by thermal process are promising sources of sustainable, low greenhouse gas alternative fuels. These thermal processes are also well suited to decentralized energy production due to low capital and operating costs. Algae feedstocks for bio-oil production are of particular interest, due in part to their high-energy growth yields. Further, algae can be grown in non-arable areas in fresh, brackish, salt water, or even waste water. Unfortunately, bio-oils produced by thermal processes present significant stability challenges. These oils have complex chemical compositions, are viscous, reactive, and thermally unstable. Further, the components within the oils are difficult to separate by fractional distillation. By far, the most effective separation and stabilization method has been solvent extraction. However, liquid phase extraction processes pose two main obstacles to commercialization; they require a significant amount of energy to remove and recover the solvent from the product, and they have a propensity for the solvent to become contaminated with minerals from the char and ash present in the original bio-oil. Separation and fractionation of thermally produced bio-oils using supercritical fluids (SCF) offers the advantages of liquid solvent extraction while drastically reducing energy demands and the predisposition to carry over solids into the extracted phase. SCFs are dense fluids with liquid-like solvent properties and gas-like transport properties. Further, SCF density and solvent strength can be tuned with minor adjustments in pressure, co-solvent addition, or gas anti-solvent addition. Catalytic pyrolysis oils were produced from Scenedesmus dimorphus algae using a fluid catalytic cracking catalyst. Bio-oil produced from catalytic fast pyrolysis (CFP) was separated using critical fluids. Propane extraction was performed at 65 °C at a fluid reduced pressure of 2.0 (85 bar) using an eight to one solvent to feed ratio by weight. Extraction of

Objective: To evaluate the effect of hepatitis B prevention and control by comparative analysis on the results of HBsAg, anti-HBs and anti-HBc prevalence from national hepatitis B seroepidemiological surveys in 1992 and 2014 in different epidemic regions of China. Methods: Data was from the national seroepidemiological surveys of hepatitis B conducted in 1992 and 2014. The survey in 1992 was conducted in 145 disease surveillance points of 30 provinces (excluding Hong Kong, Macao Special Administrative Region and Taiwan province) in China. The survey in 2016 was conducted in 160 disease surveillance points of 31 provinces (excluding Hong Kong, Macao Special Administrative Region and Taiwan province) in China. In the two surveys, face-to-face interviews with the subject by door to door or on the investigation site were conducted by trained staff using standard questionnaires to obtain basic information including birth date, gender, ethnicity, resident place and so on. And then 5 ml venous blood was collected to test the sero-markers of HBsAg, anti-HBs and anti-HBc. We analyzed unweighted point prevalence and 95 % CI of HBsAg, anti-HBs and anti-HBc in 1992 which had no design weighting, and analyzed weighted point prevalence and 95 %CI of HBsAg, anti-HBs and anti-HBc in 2014 which had design weighting. Results: 34 291 and 31 713 people aged 1-29 years were involved in 1992 and 2014 national serosurveys of China, respectively. For the people aged 1-29 years, HBsAg prevalence was 2.64% (95 %CI: 2.28%-3.06%) in 2014 and decreased by 73.92% as compared with the rate 10.13% (95 % CI: 9.81%-10.45%) in 1992. Anti-HBc prevalence was 13.01% (95 %CI: 12.09%-14.00%) in 2014 and decreased by 71.61% as compared with the rate 45.84% (95 % CI: 45.31%-46.37%) in 1992.

Full Text Available Abstract Background Current epidemiological data highlight the potential detrimental associations between sedentary behaviours and health outcomes, yet little is known about temporal trends in adult sedentary time. This study used time use data to examine population trends in sedentary behaviours in non-occupational domains and more specifically during leisure time. Methods We conducted secondary analysis of population representative data from the Australian Time Use Surveys 1992, 1997 and 2006 involving respondents aged 20 years and over with completed time use diaries for two days. Weighted samples for each survey year were: n = 5851 (1992, n = 6419 (1997 and n = 5505 (2006. We recoded all primary activities by domain (sleep, occupational, transport, leisure, household, education and intensity (sedentary, light, moderate. Adjusted multiple linear regressions tested for differences in time spent in non-occupational sedentary behaviours in 1992 and 1997 with 2006 as the reference year. Results Total non-occupational sedentary time was slightly lower in 1997 than in 2006 (mean = 894 min/2d and 906 min/2d, respectively; B = −11.2; 95%CI: -21.5, -0.9. Compared with 2006, less time was spent in 1997 in sedentary transport (B-6.7; 95%CI: -10.4, -3.0 and sedentary education (B = −6.3; 95%CI: -10.5, -2.2 while household and leisure sedentary time remained stable. Time engaged in different types of leisure-time sedentary activities changed between 1997 and 2006: leisure-time computer use increased (B = −26.7; 95%CI: -29.5, -23.8, while other leisure-time sedentary behaviours (e.g., reading, listening to music, hobbies and crafts showed small concurrent reductions. In 1992, leisure screen time was lower than in 2006: TV-viewing (B = −24.2; 95%CI: -31.2, -17.2, computer use (B = −35.3; 95%CI: -37.7, -32.8. In 2006, 90 % of leisure time was spent sedentary, of which 53 % was screen time. Conclusions Non

Propane is a key component of liquefied petroleum gas (LPG) and crude oil volatile. This issue summarizes the recent progress of propane detection technology. Meanwhile, base on the development trend, our latest progress is also provided. We demonstrated a mid infrared propane sensor system, which is based on wavelength modulation spectroscopy (WMS) technique with a CW interband cascade laser (ICL) emitting at 3370.4nm. The ICL laser scanned over a sharp feature in the broader spectrum of propane, and harmonic signals are obtained by lock-in amplifier for gas concentration deduction. The surrounding gas is extracted into the fine optical absorption cell through the pump to realize online detection. The absorption cell is designed in mid infrared windows range. An example experimental setup is shown. The second harmonic signals 2f and first harmonic signals1f are obtained. We present the sensor performance test data including dynamic precision and temperature stability. The propane detection sensor system and device is portable can carried on the mobile inspection vehicle platforms or intelligent robot inspection platform to realize the leakage monitoring of whole oil gas tank area.

In early 1992, a CSF epizootic was clinically recognised in a wild boar population of approximately 1300 animals within an area of 250km(2) located in the east of France. In order to check the CSF situation in wild boars outside this area, a serological survey was carried out in the rest of France, for 8 consecutive years (1991-1998). This paper reports on the results obtained during this survey which included wild boars shot during the hunting period but also boars reared within fences. Around 1000-2700 sera a year were tested for the presence of antibodies to classical swine fever virus (CSFV) and also to Aujeszky's disease virus (ADV). Out of 12025 sera tested over the whole period, 80 wild boars were found positive for CSF antibodies. Sixty of them were collected on wild boars shot during the years 1992-1994 in the epizootic area located in east of France and 10 were collected in Corsica during the years 1994-1996. The last four positive samples were single reactors coming from areas or farms, which were thereafter confirmed to be serologically negative. These results together with the fact that no disease has been reported so far illustrate that the French wild boar population is probably not concerned by CSF infection (excepted in the east of France where the disease has now become enzootic). Two hundred and forty nine sera were initially detected as CSF positive but confirmed secondarily as positive for border disease (BD) antibodies. This finding shows that wild boars are also susceptible to infection by ruminant pestiviruses. Four hundred and twenty three wild boars have been found positive for ADV antibodies. In addition, from 1993 to 1995, 909 samples were tested for the presence of antibodies to porcine reproductive and respiratory syndrome virus (PRRSV). Thirty three of them were positive. The results on AD and PRRS antibody detection show that wild boars may constitute a reservoir for various infectious diseases of pigs.

In the propane-utilizing bacterium Gordonia sp. strain TY-5, propane was shown to be oxidized to 2-propanol and then further oxidized to acetone. In this study, the subsequent metabolism of acetone was studied. Acetone-induced proteins were found in extracts of cells induced by acetone, and a gene cluster designated acmAB was cloned on the basis of the N-terminal amino acid sequences of acetone-induced proteins. The acmA and acmB genes encode a Baeyer-Villiger monooxygenase (BVMO) and esterase, respectively. The BVMO encoded by acmA was purified from acetone-induced cells of Gordonia sp. strain TY-5 and characterized. The BVMO exhibited NADPH-dependent oxidation activity for linear ketones (C3 to C10) and cyclic ketones (C4 to C8). Escherichia coli expressing the acmA gene oxidized acetone to methyl acetate, and E. coli expressing the acmB gene hydrolyzed methyl acetate. Northern blot analyses revealed that polycistronic transcription of the acmAB gene cluster was induced by propane, 2-propanol, and acetone. These results indicate that the acmAB gene products play an important role in the metabolism of acetone derived from propane oxidation and clarify the propane metabolism pathway of strain TY-5 (propane → 2-propanol → acetone → methyl acetate → acetic acid + methanol). This paper provides the first evidence for BVMO-dependent acetone metabolism. PMID:17071761

supersaturation region. The experiments showed that the gas dissolution rate rather than the induction time of propane hydrate is influenced by a change in agitation. This was especially valid at high stirring rates when the water surface was severely disturbed.Addition of polyvinylpyrrolidone (PVP......) to the aqueous phase was found to reduce the gas dissolution rate slightly. However the induction times were prolonged quite substantially upon addition of PVP.The induction time data were correlated using a newly developed induction time model based on crystallization theory also capable of taking into account...... the presence of additives. In most cases reasonable agreement between the data and the model could be obtained. The results revealed that especially the effective surface energy between propane hydrate and water is likely to change when the stirring rate varies from very high to low. The prolongation...

Full Text Available Iron-zinc oxide films with different Zn contents were ultrasonically sprayed on glass substrates and inter-digital gold electrodes were evaporated upon them. Films were deposited from solutions containing 2, 10 and 30 at. % Zn. Hematite, amorphous and Franklinite structures turned out, respectively. They were assessed as humidity and propane detectors under alternating-current conditions for frequencies from 1 to 105 Hz and temperatures 30 and 250 oC. Their impedances in dry air, humid air and humid air plus propane were determined from voltage measurements with a Lock-In amplifier. Sensitivities to humidity (53 % RH. and 189, 500 and 786 ppm of propane from the response of the resistance, reactance and also the total impedance were determined as functions of frequency. The maximum sensitivity to humidity ranges from 24 % up to 308 %. For propane, the maximum sensitivity ranges from 45 % up to 711 %. The largest sensitivity values correspond in all cases to reactance. From the dynamical response, the response and recovery times are determined, along with the concentration-dependence of the sensitivity. The sensing mechanisms are commented.

Anaerobic methane oxidation coupled to sulphate reduction and the use of ethane and propane as electron donors by sulphate-reducing bacteria represent new opportunities for the treatment of streams contaminated with sulphur oxyanions. However, growth of microbial sulphate-reducing populations with methane, propane or butane is extremely slow, which hampers research and development of bioprocesses based on these conversions. Thermodynamic calculations indicate that the growth rate with possible alternative terminal electron acceptors such as thiosulphate and elemental sulphur may be higher, which would facilitate future research. Here, we investigate the use of these electron acceptors for oxidation of methane, ethane and propane, with marine sediment as inoculum. Mixed marine sediments originating from Aarhus Bay (Denmark) and Eckernförde Bay (Germany) were cultivated anaerobically at a pH between 7.2 and 7.8 and a temperature of 15 °C in the presence of methane, ethane and propane and various sulphur electron acceptors. The sulphide production rates in the conditions with methane, ethane and propane with sulphate were respectively 2.3, 2.2 and 1.8 μmol S L(-1) day(-1). For sulphur, no reduction was demonstrated. For thiosulphate, the sulphide production rates were up to 50 times higher compared to those of sulphate, with 86.2, 90.7 and 108.1 μmol S L(-1) day(-1) for methane, ethane and propane respectively. This sulphide production was partly due to disproportionation, 50 % for ethane but only 7 and 14 % for methane and propane respectively. The oxidation of the alkanes in the presence of thiosulphate was confirmed by carbon dioxide production. This is, to our knowledge, the first report of thiosulphate use as electron acceptor with ethane and propane as electron donors. Additionally, these results indicate that thiosulphate is a promising electron acceptor to increase start-up rates for sulphate-reducing bioprocesses coupled to short-chain alkane oxidation.

Bio-Propane from glycerol for biogas addition

In this report, the technical and economical feasibility to produce higher alkanes from bioglycerol has been investigated. The main purpose of producing this kind of chemicals would be to replace the fossil LPG used in upgraded biogas production. When producing biogas and exporting it to the natural gas grid, the Wobbe index and heating value does not match the existing natural gas. Therefore, the upgraded biogas that is put into the natural gas grid in Sweden today contains 8-10 vol-% of LPG. The experimental work performed in association to this report has shown that it is possible to produce propane from glycerol. However, the production of ethane from glycerol may be even more advantageous. The experimental work has included developing and testing catalysts for several intermediate reactions. The work was performed using different micro-scale reactors with a liquid feed rate of 18 g/h. The first reaction, independent on if propane or ethane is to be produced, is dehydration of glycerol to acrolein. This was showed during 60 h on an acidic catalyst with a yield of 90%. The production of propanol, the second intermediate to producing propane, was shown as well. Propanol was produced both using acrolein as the starting material as well as glycerol (combining the first and second step) with yields of 70-80% in the first case and 65-70% in the second case. The propanol produced was investigated for its dehydration to propene, with a yield of 70-75%. By using a proprietary, purposely developed catalyst the propene was hydrogenated to propane, with a yield of 85% from propanol. The formation of propane from glycerol was finally investigated, with an overall yield of 55%. The second part of the experimental work performed investigated the possibilities of decarbonylating acrolein to form ethane. This was made possible by the development of a proprietary catalyst which combines decarbonylation and water-gas shift functionality. By combining these two functionalities, no

1992-01-01

Alberta Oil Sands Equity (AOSE) manages the Alberta government's equity investments in oil sands and heavy oil projects. AOSE is a 16.74% participant in the Syncrude Project, a 10% participant in the OSLO (Other Six Leases Operation) Commercial Project and the OSLO New Ventures project, and a 24.17% participant in the Lloydminster Bi-Provincial Upgrader. Syncrude produces over 11% of Canadian crude oil requirements, and AOSE's share yielded $43.3 million profit for 1991/92, down significantly from the $82.1 million the previous year due to lower oil prices. The OSLO Commercial Project is a proposed commercial oil sands plant with a mine site and extraction plant to be located north of Fort McMurray, and an upgrading facility to be situated north of Edmonton. Work on this project was suspended in early 1992. The OSLO New Ventures project will handle the exploration and development of the remaining five oil sands leases plus the southern portion of Lease 31. As of March 31, 1992, the project owners were considering a commercial demonstration project utilizing dredging and cold-water extraction processes. Two of the owners are unable to provide funding and discussions are under way to resolve the matter and move the program forward. The Lloydminster Bi-Provincial Upgrader was nearly 90% complete in March 1992 and full startup is expected in November 1992; engineering work was completed in March 1991. The upgrader will increase the value of heavy crude oil and thereby increase its demand. 4 figs., 4 tabs

Advanced energy projects FY 1992 research summaries

International Nuclear Information System (INIS)

1992-09-01

The Division of Advanced Energy Projects (AEP) provides support to explore the feasibility of novel, energy-related concepts that evolve from advances in basic research. These concepts are typically at an early stage of scientific definition and, therefore, are beyond the scope of ongoing applied research or technology development programs. The Division provides a mechanism for converting basic research findings to applications that eventually could impact the Nation's energy economy. Technical topics include physical, chemical, materials, engineering, and biotechnologies. Projects can involve interdisciplinary approaches to solve energy-related problems. Projects are supported for a finite period of time, which is typically three years. Annual funding levels for projects are usually about $300,000 but can vary from approximately $50,000 to $500,000. It is expected that, following AEP support, each concept will be sufficiently developed and promising to attract further funding from other sources in order to realize its full potential. There were 39 research projects in the Division of Advanced Energy Projects during Fiscal Year 1992 (October 1, 1991 -- September 30, 1992). The abstracts of those projects are provided to introduce the overall program in Advanced Energy Projects. Further information on a specific project may be obtained by contacting the principal investigator, who is listed below the project title. Projects completed during FY 1992 are indicated

The level analysis of the level of radioactive contamination in environment and food samples was carried out in Poland in 1992. The results were compared to the data from 1985-1991 period. Since the Chernobyl accident gradual decrease of contamination level has been stated. The gamma dose rate and the contamination of air, fallout, tap and surface water were at the level of 1985. Still higher contamination level of cesium isotopes in soil has been reported and as a consequence food contamination was higher particularly the animal food. Actually, the source of additional dose is ingestion of artificial isotopes with food as a result of food contamination. The average effective dose equivalent, due to the contaminated food consumption, was estimated at the level 15 μSv for a Pole in 1992. (author). 13 refs, 6 figs, 20 tabs

MEA [Municipal Electric Association] declares opposition to 1991 Ontario Hydro rate increase

International Nuclear Information System (INIS)

Anon.

1991-01-01

In hearings before the Ontario Energy Board, the Municipal Electric Association (MEA) called for an average 1992 rate increase of 10.3%, lower than Ontario Hydro's revised figure of 10.4%, and a $129 million reduction in its operations, maintenance and administration budget. As it has been noted that Hydro pays considerably higher wages than the surrounding reference community, MEA recommended that the utility reduce and eventually eliminate the premium paid to employees, and also called for staff reductions and layoffs for 1991 and 1992. In the area of transmission reliability, MEA stated that Ontario Hydro's transmission maintenance is suffering at the expense of other priorities, and called for reorganizing its transmission plan to achieve target performance by 1996 rather than 1999. In 1991, only 65-70% of maintenance targets were being achieved. MEA also accused Hydro of deferring operational expenditures into deferment and capitalization, creating a false picture of the utility's financial condition. Also discussed at the hearing were the possible overestimating of the effects of Ontario Hydro's demand management programs, the possibility that a shift to time-of-use rates for industrial customers may increase demand, a downgrading of the province's and the utility's credit rating, and the unpleasant side effects of the non-utility generation program

School districts across the country are under pressure to reduce their cost of operations and ensure their budgets are spent wisely. School bus fleets operate more than 675,000 buses in the United States, and many school districts have found the answer to their budget woes in the form of propane, or liquefied petroleum gas (LPG). Propane is a reliable, domestic fuel, and it's used in approximately 2% of school buses nationwide.

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During second quarter 1992, EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of criteria to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identification. Since 1991, the flagging criteria have been based on the federal Environmental Protection Agency (EPA) drinking water standards and on method detection limits. A detailed explanation of the current flagging criteria is presented in the Flagging Criteria section of this document. Analytical results from second quarter 1992 are listed in this report.

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.

The 1991 Research Report of the Hohenheim University near Stuttgart is based on data collected in 1989 and extensively in 1990 and 1991. The progress reports were sent to all of the faculties, institutions, particular research areas and centres of the University. Questions were posed regarding current and recently completed projects. The final version was adapted for print. The survey also enquired about financial support from third parties. The numerous contacts abroad of the Hohenheim University are also documented in this book. Finally, it was asked under which of the nine main Hohenheim research programme headings the particular project could be listed. (orig.) [de

Assessment of propane/commercial butane mixtures as possible alternatives to R134a in domestic refrigerators

Fatouh, M.; El Kafafy, M.

2006-01-01

The possibility of using hydrocarbon mixtures as working fluids to replace R134a in domestic refrigerators has been evaluated through a simulation analysis in the present work. The performance characteristics of domestic refrigerators were predicted over a wide range of evaporation temperatures (-35 to -10 o C) and condensation temperatures (40-60 deg. C) for various working fluids such as R134a, propane, commercial butane and propane/iso-butane/n-butane mixtures with various propane mass fractions. The performance characteristics of the considered domestic refrigerator were identified by the coefficient of performance (COP), volumetric cooling capacity, cooling capacity, condenser capacity, input power to compressor, discharge temperature, pressure ratio and refrigerant mass flow rate. The results showed that pure propane could not be used as a drop in replacement for R134a in domestic refrigerators because of its high operating pressures and low COP. Commercial butane yields many desirable characteristics but requires a compressor change. The coefficient of performance of the domestic refrigerator using a ternary hydrocarbon mixture with propane mass fractions from 0.5 to 0.7 is higher than that of R134a. Comparison among the considered working fluids confirmed that the average refrigerant mass flow rate of the propoane/commercial butane mixture is 50% lower than that of R134a. Also, the results indicated that R134a and the propoane/commercial butane mixture with 60% propane mass concentration have approximately the same values of saturation pressure, compressor discharge temperature, condenser heat load, input power, cooling capacity and volumetric cooling capacity. However, the pressure ratio of the hydrocarbon mixture with 60% propane is lower than that of R134a by about 11.1%. Finally, the reported results confirmed that the propane/iso-butane/n-butane mixture with 60% propane is the best drop in replacement for R134a in domestic refrigerators under normal

How propane supply and demand in North America affects prices in Alberta

International Nuclear Information System (INIS)

Hall, D.

2000-01-01

Total North American demand for propane in 1999 was estimated at 1,700 MBPD, of which 1,300 MBPD represents demand by the United States. World-wide demand is about 3,500 MBPD, Europe and the Mid East combined, and Asia, each accounting for 800 to 850 MBPD. The United States is able to supply about 1,000 MBPD of its own demand ; the rest comes from imports. Total imports make up about 12 per cent of the U.S. supply; in 1999 just over 80 per cent, or about 120 MBPD of the imported propane came from Canada. The volume of export from Canada to the United states is expected to rise to about 170 MBPD, or 86 per cent of the total domestic supply shortfall in 2000. Prices at Edmonton ranged between 35 cents per gallon in Jan 1997, to about 42 cents per gallon in January 2000; during much of this period (from July 1997 to July 1999) the price was below 30 cents per gallon and as low as about 15 cents per gallon in January 1999. The price differential between Edmonton and Conway (the receiving point in the United States) was an average of 6 cents (US) per gallon. Total U.S. propane inventories during the same period and propane inventories against heating degree days and Conway propane prices are also shown in graphic form. The various graphs illustrate that in general, the price of propane at any given time is heavily influenced by the price of crude oil, however, in the short term competing fuels, weather conditions and inventory levels also play a part in determining prices. With regard to the future, a bullish outlook envisages flat to current prices, whereas a bearish outlook forecasts lower prices due to softening of the world economy, high U.S. and Canadian inventories, and the possibility of another warm winter. 18 viewgraphs

The Phase I effort demonstrated the technical viability of a fast, sensitive, mobile hydrocarbon monitor. The instrument will enable the oil and gas industry, researchers, and regulators to rapidly identify and chemically profile leaks from facilities. This capability will allow operators to quickly narrow down and mitigate probable leaking equipment, minimizing product loss and penalties due to regulatory non-compliance. During the initial development phase, we demonstrated operation of a prototype monitor that is capable of measuring methane, ethane, and propane at sub-part-per-billion sensitivities in 1 second, using direct absorption infrared spectroscopy. To our knowledge, this is the first instrument capable of fast propane measurements at atmospheric concentrations. In addition, the electrical requirements of the monitor have been reduced from the 1,200 W typical of a spectrometer, to <500 W, making it capable of being powered by a passenger vehicle, and easily deployed by the industry. The prototype monitor leverages recent advances in laser technology, using high-efficiency interband cascade lasers to access the 3 μm region of the mid-infrared, where the methane, ethane, and propane absorptions are strongest. Combined with established spectrometer technology, we have achieved precisions below 200 ppt for each compound. This allows the monitor to measure fast plumes from oil and gas facilities, as well as ambient background concentrations (typical ambient levels are 2 ppm, 1.5 ppb, and 0.7 ppb for methane, ethane and propane, respectively). Increases in instrument operating pressure were studied in order to allow for a smaller 125 W pump to be used, and passive cooling was explored to reduce the cooling load by almost 90% relative to active (refrigerated) cooling. In addition, the simulated infrared absorption profiles of ethane and propane were modified to minimize crosstalk between species, achieving <1% crosstalk between ethane and propane. Finally, a

The U.S. Geological Survey (USGS) conducted a Pressure Sensor Workshop, oriented toward the measurement of stage in surface waters, in Denver, Colorado, July 28-31, 1992. Twenty attendees from the U.S. Geological Survey and the National Oceanic and Atmospheric Administration gave presentations concerning their experiences with the use of pressure sensors in hydrologic investigations. This report is a compilation of the abstracts of the presentations made at the workshop. Workshop participants concluded that each of the sensors evaluated by the U.S. Geological Survey has strengths and weaknesses. Personnel contemplating the use of pressure sensors discussed at this workshop should contact workshop attendees and consult with them about their experiences with those sensors. The attendees preferred to use stilling wells with float-operated water-level sensors as the primary means for monitoring water levels. However, pressure sensor systems were favored as replacements for mercury manometers and as alternatives to stilling wells at sites where stilling wells are not practical or cost effective.

Canada's future role as a propane supplier for the US market

Energy Technology Data Exchange (ETDEWEB)

Anderson, A.B.; Zittlau, W.T.

In Canada, the fall of world crude oil prices that took hold at the beginning of 1986 coincided with the early stages of a long awaited program to dismantle the federal and provincial governments' regulatory framework for the industry. The momentum to deregulate has continued with the industry's support and most recently was manifested by the signing of The Canada-US Free Trade Agreement. Canada has historically been the major supplier of imported propane to the US market. This paper presents one producer and marketer's appraisal of the role Canada is likely to play in meeting US propane shortfalls through the 1990s. Canadian natural gas production will expand considerably during the 1990s to meet a modest expandion of domestic demand and in response to the growing opportunities of the US export market. Current forecasts suggest that gas exports to the US will increase from just under the 1 Tcf level achieved in 1987 to the 1.8 Tcf range by 1995/2000, thus pushing total sales of Canadian gas to 4.3 Tcf by 2000. The other factor to be considered when forecasting propane production from natural gas streams is the liquids content of the gas. Canadian end-use markets for propane are similar to those in the US: residential and commercial space heating, crop drying, specialty industrial applications, transportations and petrochemicals. In addition, over the next five years growing volumes are expected to be used in miscible flood projects. The petrochemical sector accounts for the balance of final consumption of propane in Canada. Based on the foregoing supply/demand analysis the authors see Canadian propane surpluses growing from an estimated 50 thousand b/d achieved in 1987 to nearly 65 thousand b/d in the early 1990s.

Surface Termination of M1 Phase and Rational Design of Propane Ammoxidation Catalysts

This final report describes major accomplishments in this research project which has demonstrated that the M1 phase is the only crystalline phase required for propane ammoxidation to acrylonitrile and that a surface monolayer terminating the ab planes of the M1 phase is responsible for their activity and selectivity in this reaction. Fundamental studies of the topmost surface chemistry and mechanism of propane ammoxidation over the Mo-V-(Te,Sb)-(Nb,Ta)-O M1 and M2 phases resulted in the development of quantitative understanding of the surface molecular structure – reactivity relationships for this unique catalytic system. These oxides possess unique catalytic properties among mixed metal oxides, because they selectively catalyze three alkane transformation reactions, namely propane ammoxidation to acrylonitrile, propane oxidation to acrylic acid and ethane oxidative dehydrogenation, all of considerable economic significance. Therefore, the larger goal of this research was to expand this catalysis to other alkanes of commercial interest, and more broadly, demonstrate successful approaches to rational design of improved catalysts that can be applied to other selective (amm)oxidation processes.

Jilek, P.; Novotny, V. [Ministry of the Environment of the Czech Republic, Prague (Czechoslovakia)

1995-12-01

Environmental issues, especially the solution of the air pollution problem, have taken on great significance in the Czech Republic (which was a part of the Czech and Slovak Federal Republic until the end of 1992) since the 1989 {open_quotes}Velvet{close_quotes} Revolution. The former CSFR Federal Committee for the Environment and both the Republic Ministries started immediately with creating new environmental legislation, which is the main governmental tool for protecting the environment in the newly developing democracy state system with a market oriented economy. The inspiration for that activity was found in legislation of developed countries - member states of the European Union, and in German environmental law in particular. This paper surveys the major laws and regulations that gradually came into force in the Czech Republic since 1990. The provisions of the primary significance are the Act No.309/1991 S.B., dated July 9, 1991, on the protection of the air against pollutants - The Clean Air Act, the Act No.218/1992 S.B., dated April 27, 1992, which changes and supplements the Act No.309 - The Clean Air Act, the Measure of the Federal Committee for the Environment of October 1, 1991 to the Clean Air Act, and its amended wordings of June 23, 1992, 84/1991 S.B., and 84/1992 S.B., the Act No.389/1991 S.B., dated September 10, 1991 on the state administration of air protection and charges for the pollution of air, and several regulations based on the Act No.389/1991 S.B., issued in the period 1992 -1993.

In this paper we will report the results of nation-wide surveys on employee health conducted and published by the Ministry of Labour in 1982, 1987, and 1992. The subjects were approximately 20,000 employees in 1982, approximately 15,000 in 1987, and approximately 16,000 in 1992, from throughout Japan. Using the results of the surveys, we will show trends in the status of employee work-related stress, as well as trends in means of relaxation over the past decade. The percentage of employees with work-related stress among all subjects gradually increased as follows: 50.6% in 1982, 55.0% in 1987, and 57.3% in 1992. The percentage of employees with work-related stress increased remarkably from 1982 through 1992 among the following groups: the 50-59 age group in males; employees in the electricity, gas, heat and water-supply industries; those in the real estate industry; administrative and managerial workers; employees of large establishments with more than 5,000 employees; and employees performing shift work involving no night duty. The problem of "human relationships in the workplace" was associated with the increasing stress levels among 50-59-year-old males, 40-49-year-old females, employees of large establishments with more than 5,000 employees, those in the real estate industry, and service workers. In terms of means of relaxing to relieve fatigue and stress, employees tended to engage in active pursuits such as "eating out and shopping" and "driving and traveling" over the past decade. In 1992, on the other hand, 22.0% of males and 5.9% of females selected "smoking" as a means of relaxation. This shows the need for stress management in the workplace in order to prevent health problems related to smoking.

Ethane and propane are the most abundant non-methane hydrocarbons in the atmosphere. However, their emissions, atmospheric distribution, and trends in their atmospheric concentrations are insufficiently understood. Atmospheric model simulations using standard community emission inventories do not reproduce available measurements in the Northern Hemisphere. Here, we show that observations of pre-industrial and present-day ethane and propane can be reproduced in simulations with a detailed atmospheric chemistry transport model, provided that natural geologic emissions are taken into account and anthropogenic fossil fuel emissions are assumed to be two to three times higher than is indicated in current inventories. Accounting for these enhanced ethane and propane emissions results in simulated surface ozone concentrations that are 5-13% higher than previously assumed in some polluted regions in Asia. The improved correspondence with observed ethane and propane in model simulations with greater emissions suggests that the level of fossil (geologic + fossil fuel) methane emissions in current inventories may need re-evaluation.

This paper reports the activities of the environmental safety evaluation sub-committee for the coal liquefaction plant in fiscal 1992. The sub-committee, upon having received reports on the result of environmental safety evaluation tests performed in fiscals 1991 and 1992 by NEDO, deliberated and discussed carefully the contents thereof. In order to ensure labor hygiene for coal liquefaction plant workers, health influence on liquefied oil users, and social acceptability of the liquefied oil, NEDO has performed the comprehensive brown coal pilot plant operation and oil safety tests. The tests are in accordance with the labor safety and hygiene law, the chemicals examination law, and the MPD issued by OECD, and performed on each fraction produced in the pilot plant and the whole fraction mixing the former fractions, using rats, rabbits, and guinea pigs. The test items included: acute inhalation toxicity and oral repeated administration (using rats); eye stimulation, repeated coating and skin stimulation (using rabbits); photo-toxicity (using guinea pigs); mutagenicity tests (microorganisms, bacteria and chromosome anomaly); resolution tests; fish toxicity; concentration degrees; algae growth obstruction; and water flea breeding obstruction. As the result, the toxicity was found light. (NEDO)

Site-Specific Hydrogen Isotope Composition of Propane: Mass spectrometric methods, equilibrium temperature dependence, and kinetics of exchange

Intramolecular isotope ordering can constrain temperatures of synthesis, mechanisms of formation, and/or source substrates of organic compounds. Here we explore site-specific hydrogen isotope variations of propane. Statistical thermodynamic models predict that at equilibrium methylene hydrogen (-CH2-) in propane will be 10's of per mil higher in D/H ratio than methyl hydrogen (-CH3) at geologically relevant temperatures, and that this difference is highly temperature dependent ( 0.5-1 ‰/°C). Chemical-kinetic controls on site-specific D/H in propane could constrain the mechanisms, conditions and extents of propane synthesis or destruction. We have developed a method for measuring the difference in D/H ratio between methylene and methyl hydrogen in propane by gas source mass spectrometry. The data were measured using the Thermo Fisher Double Focusing Sector high resolution mass spectrometer (DFS), and involve comparison of the D/H ratios of molecular ion (C3H8+) and the ethyl fragmental ion (C2H5+). We demonstrate the accuracy and precision of this method through analysis of D-labeled and independently analyzed propanes. In the exchange experiments, propane was heated (100-200 oC) either alone or in the presence of D-enriched water (δD=1,1419 ‰ SMOW), with or without one of several potentially catalytic substrates for hours to weeks. Propane was found to exchange hydrogen with water vigorously at 200 °C in the presence of metal catalysts. In the presence of Ni catalyst, methylene hydrogen exchanges 2.5 times faster than methyl hydrogen. Hydrogen exchange in the presence of Pd catalyst is more effective and can equilibrate hydrogen isotope distribution on propane on the order of 7 days. Isotopic exchange in the presence of natural materials have also been tested, but is only measurable in the methylene group at 200 °C. High catalytic activity of Pd permits attainment of a bracketed, time-invariant equilibrium state that we use to calibrate the site

The Atmospheric Impact of the 1991 Mount Pinatubo Eruption

1993-01-01

The 1991 eruption of Pinatubo produced about 5 cubic kilometers of dacitic magma and may be the second largest volcanic eruption of the century. Eruption columns reached 40 kilometers in altitude and emplaced a giant umbrella cloud in the middle to lower stratosphere that injected about 17 megatons of SO2, slightly more than twice the largest yielded by the 1982 eruption of El Chichon, Mexico. The SO2 formed sulfate aerosols that produced the largest perturbation to the stratospheric aerosol layer since the eruption of Krakatau in 1883. The aerosol cloud spread rapidly around the Earth in about 3 weeks and attained global coverage by about 1 year after the eruption. Peak local midvisible optical depths of up to 0.4 were measured in late 1992, and globally averaged values were about 0.1 to 0.15 for 2 years. The large aerosol cloud caused dramatic decreases in the amount of net radiation reaching the Earth's surface, producing a climate forcing that was two times stronger than the aerosols of El Chichon. Effects on climate were an observed surface cooling in the northern hemisphere of up to 0.5 to 0.6 C, equivalent to a hemispheric-wide reduction in net radiation of 4 watts per square meter and a cooling of perhaps as large as -0.4 C over large parts of the earth in 1992-93. Climate models seem to have predicted the cooling with a reasonable degree of accuracy. The Pinatubo climate forcing was stronger than the opposite warming of either the El Nino event or anthropogenic greenhouse gases in the period 1991-93. As a result of the presence of the aerosol particles, midlatitude ozone concentrations reached their lowest levels on record during 1992-93, the southern hemisphere 'ozone hole' increased in 1992 to an unprecedented size and ozone depletion rates were observed to be faster than ever before recorded. The atmospheric impact of the Pinatubo eruption has been profound, and it has sparked a lively interest in the role that volcanic aerosols play in climate change

Oxygen-assisted conversion of propane over metal and metal oxide catalysts

Energy Technology Data Exchange (ETDEWEB)

Laate, Leiv

2002-07-01

An experimental set-up has been build and applied in activity/selectivity studies of the oxygen-assisted conversion of propane over metals and metal oxide catalysts. The apparatus has been used in order to achieve an improved understanding of the reactions between alkanes/alkenes and oxygen. Processes that have been studied arc the oxidative dehydrogenation of propane over a VMgO catalyst and the selective combustion of hydrogen in the presence of hydrocarbons over Pt-based catalysts and metal oxide catalysts. From the experiments, the following conclusions are drawn: A study of the oxidative dehydrogenation of propane over a vanadium-magnesium-oxide catalyst confirmed that the main problem with this system is the lack of selectivity due to complete combustion. Selectivity to propene up to about 60% was obtained at 10% conversion at 500{sup o}C, but the selectivity decreased with increasing conversion. No oxygenates were detected, the only by- products were CO and CO{sub 2}. The selectivity to propene is a strong function of the conversion of propane. The reaction rate of propane was found to be 1.0 {+-} 0.1 order in propane and 0.07 {+-} 0.02 order in oxygen. The kinetic results are in agreement with a Mars van Krevelen mechanism with the activation of the hydrocarbons as the slow step. The rate of propene oxidation to CO{sub 2} was studied and found to be significantly higher than that of propane. Another possible process involves the simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to shift the equilibrium dehydrogenation reaction further to the product alkenes. A study of the selective combustion of hydrogen in the presence of propane/propene was found to be possible under certain reaction conditions over some metal oxide catalysts. In{sub 2}O{sub 3}/SiO{sub 2}, unsupported Bi{sub 2}O{sub 3} and ZSM-5 show the ability to combust hydrogen in a gas mixture with propane and oxygen with good selectivity. Bi{sub 2

Maloney, T.J.; Ludtke, A.S.; Krizman, T.L.

1994-01-01

The US. Geological Survey operates a quality- assurance program based on the analyses of reference samples for the National Water Quality Laboratory in Arvada, Colorado, and the Quality of Water Service Unit in Ocala, Florida. Reference samples containing selected inorganic, nutrient, and low ionic-strength constituents are prepared and disguised as routine samples. The program goal is to determine precision and bias for as many analytical methods offered by the participating laboratories as possible. The samples typically are submitted at a rate of approximately 5 percent of the annual environmental sample load for each constituent. The samples are distributed to the laboratories throughout the year. Analytical data for these reference samples reflect the quality of environmental sample data produced by the laboratories because the samples are processed in the same manner for all steps from sample login through data release. The results are stored permanently in the National Water Data Storage and Retrieval System. During water year 1991, 86 analytical procedures were evaluated at the National Water Quality Laboratory and 37 analytical procedures were evaluated at the Quality of Water Service Unit. An overall evaluation of the inorganic (major ion and trace metal) constituent data for water year 1991 indicated analytical imprecision in the National Water Quality Laboratory for 5 of 67 analytical procedures: aluminum (whole-water recoverable, atomic emission spectrometric, direct-current plasma); calcium (atomic emission spectrometric, direct); fluoride (ion-exchange chromatographic); iron (whole-water recoverable, atomic absorption spectrometric, direct); and sulfate (ion-exchange chromatographic). The results for 11 of 67 analytical procedures had positive or negative bias during water year 1991. Analytical imprecision was indicated in the determination of two of the five National Water Quality Laboratory nutrient constituents: orthophosphate as phosphorus and

Highlights: • New speed of sound data for six propane derivatives is reported. • Temperature and pressure ranges: (283.15–343.15) K and (0.1–95) MPa. • Data are compared with those available for other propane derivatives. • Temperature and pressure dependencies of sound speed are analyzed. - Abstract: The speed of sound in the temperature and pressure intervals (283.15–343.15) K and (0.1–95) MPa was measured for nitropropane, propionitrile, 1,2-dichloropropane, 1,3-dichloropropane, propylamine and propionic acid. An apparatus based on the acoustic wave time of flight determination, with a fully automatized temperature and pressure control, was used to this aim. The speed of sound derivatives against temperature and pressure, as well as the nonlinear acoustic coefficient was obtained from experimental values. The results are analyzed and compared with previously reported data for other propane derivatives: propane, 1-propanol, propanone, d-propanone, and several fluoropropanes. All obtained magnitudes are rationalized basing on the physicochemical properties of these fluids. Nearness to critical point and molar mass are revealed as key factors as regards the speed of sound behavior against temperature and pressure.

Neff, J.M.; Owens, E.H.; Stoker, S.W.; McCormick, D.M.

1995-01-01

Following the Exxon Valdez oil spill of March 24, 1989, in Prince William Sound, Alaska, Exxon conducted comprehensive, systematic shoreline surveys in cooperation with federal and state authorities to obtain information on the distribution and magnitude of shoreline oiling and to identify natural and cultural resources requiring special protection. Similar joint surveys were performed during the springs of 1990, 1991, and 1992 on all Prince william Sound and Gulf of Alaska shorelines that were suspected of having remnants of weathered oil and that would benefit from further cleanup. In the springs of 1990, 1991, and 1992, isolated pockets of subsurface oil were found, chiefly in small scattered zones in coarse cobble/boulder sediments in the upper intertidal or supratidal zones. In 1991, about one-third of the subdivisions in Prince William Sound with surface oil also contained some subsurface oil. The areal extent of this subsurface oil declined by nearly 70% between 1991 and 1992, from about 37,000 m 2 to about 12,000 m 2 . Moreover, where subsurface oil remained in 1992, it was present in lesser amounts. Rates of oil removal were greatest on coastal sections treated early in the spring and summer of 1989. Where shoreline treatment was delayed, the subsequent rate of removal of oil from the shore by natural processes was slower. 27 refs., 10 figs., 3 tabs

Saturated liquid densities of propane at T = (280 to 365) K

International Nuclear Information System (INIS)

Miyamoto, H.; Uematsu, M.

2007-01-01

Saturated liquid densities for propane were obtained by means of a metal-bellows variable volumometer at T = (280, 300, 320, 340, 360, and 365) K. The mol-fraction purity of the propane used in the measurements was 0.99997. The expanded uncertainties (k = 2) in temperature, pressure, and density measurements were estimated to be less than ±3 mK, 1.4 kPa (p ≤ 7 MPa), and ±0.09%, respectively. For the determination of the saturation boundary at each temperature for propane, we measured the density data at intervals of about 20 kPa very close to the saturation boundary. After such measurements had been completed, the saturated liquid density data at each temperature were determined as the intersection between the isotherm and our previously determined vapour pressure value. The discrepancies between the three series in the present measurements, in which different sample fillings were used, were also confirmed to be sufficiently lower than the experimental uncertainty. The saturated liquid density correlation was also provided for the systematic comparisons between the present measurements and the literature data

Production acceleration and injectivity enhancement using steam-propane injection for Hamaca extra-heavy oil

2005-02-01

The possibility of enhanced recovery in the Orinoco Belt in Venezuela, the world's largest known hydrocarbon deposit, by using propane as a steam additive, is discussed. In a laboratory study the steam-propane injection accelerated the start of oil production by 21 per cent, compared to production with steam alone. The experiments illustrated that the inclusion of even small amounts of propane has considerable beneficial effect on the rate of bitumen production. Even though total bitumen recovery and ultimate residual oil saturation did not change, the acceleration of bitumen recovery is considered to have a significant impact on the net present value of the recovery process. 17 refs., 1 tab., 13 figs.

Columbia River Basin Fish and Wildlife Program Annual Implementation Work Plan for fiscal year 1992

International Nuclear Information System (INIS)

1991-09-01

The Columbia River Basin Fish and Wildlife Program Annual Implementation Work Plan (AIWP) for Fiscal Year (FY) 1992 presents Bonneville Power Administration's (BPA) plans for implementing the Columbia River Basin Fish and Wildlife Program (Program) in FY 1992. The AIWP focuses on individual Action Items found in the 1987 Program for which BPA has determined that it has authority and responsibility to implement. Each of the entries in the AIWP includes objectives, background, progress to date in achieving the objectives, and a summary of plans for implementation in FY 1992. Most Action Items are implemented through one or more BPA-funded projects. Each Action Item entry is followed by a list of completed, ongoing, and planned projects, along with objectives, results, schedules, and milestones for each project. In October 1988, BPA and the Columbia Basin Fish and Wildlife Authority (CBFWA) initiated a collaborative and cooperative Implementation Planning Process (IPP). The IPP provided opportunities in FY 1991 for the fish and wildlife agencies. Tribes, and other interested parties to be involved in planning FY 1992 Program implementation. This planing process contributed to the development of this year's AIWP. The joint BPA/CBFWA IPP is expected to continue in FY 1992. The FY 1992 AIWP emphasizes continuation of 143 ongoing, or projected ongoing Program projects, tasks, or task orders, most of which involve protection, mitigation, or enhancement of anadromous fishery resources. The FY 1992 AIWP also contains 10 new Program projects or tasks that are planned to start in FY 1992

The state of transboundary air pollution 1992 update. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

International Nuclear Information System (INIS)

1993-01-01

This ninth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains documents reviewed and approved for publication at the tenth session of the Executive Body held at Geneva from 17 to 19 November 1992. Part One is the Annual Review of Strategies and Policies for Air Pollution Abatement. It is compiled on the basis of national data and reports received up to 31 December 1992. National emission data and forecasts for sulphur dioxide (SO 2 ), nitrogen oxides (NO x ), volatile organic compounds (VOCs), ammonia (NH 3 ), and carbon dioxide (CO 2 ) from 1980 to the year 2005 is presented. Part Two contains results of scenario analysis for sulphur abatement strategies. It is concluded, inter alia, that strategies can be found which, by differentiating emission reductions, provide greater environmental benefit than a uniform reduction at the same cost. It is also shown that a small number of high-emitting countries in Central Europe have significant impact on deposition of sulphur throughout Europe, and that emission reduction in these countries proves to be a cost-effective way of moving towards critical loads in Europe as a whole. Most of the scenarios analysed are based on reductions of current deposition in relation to critical loads, i.e., a decrease in the exceedances of critical loads. Part Three is an executive summary of the 1992 Report on Forest Condition in Europe, carried out under the International Cooperative Programme for Assessment and Monitoring of Air Pollution Effects on Forests. The full report has been jointly published by ECE and the Commission of the European Communities. It summarizes the results of surveys carried out in 1991 in 28 European countries and in several additional regions, conducted in accordance with common guidelines.

Intermolecular potential energy surface and thermophysical properties of propane.

Science.gov (United States)

Hellmann, Robert

2017-03-21

A six-dimensional potential energy surface (PES) for the interaction of two rigid propane molecules was determined from supermolecular ab initio calculations up to the coupled cluster with single, double, and perturbative triple excitations level of theory for 9452 configurations. An analytical site-site potential function with 14 sites per molecule was fitted to the calculated interaction energies. To validate the analytical PES, the second virial coefficient and the dilute gas shear viscosity and thermal conductivity of propane were computed. The dispersion part of the potential function was slightly adjusted such that quantitative agreement with the most accurate experimental data for the second virial coefficient at room temperature was achieved. The adjusted PES yields values for the three properties that are in very good agreement with the best experimental data at all temperatures.

An aerial radiological survey of the Savannah River Site and surrounding area, Aiken, South Carolina, October--November 1991

Vojtech, R.J.

1993-12-01

An aerial radiological survey was conducted during the period of October 14 to November 23, 1991, over an area surrounding the United States Department of Energy's Savannah River Site (SRS). The area is situated 15 kilometers south of Aiken, South Carolina. The purpose of the survey was to measure and document the gamma ray environment of the SRS and surrounding areas. Contour maps showing gamma radiation exposure rates at 1 meter above ground level were constructed from the aerial data and overlaid on a United States Geological Survey map of the area. The exposure rates measured within the survey region are generally uniform and typical of natural background. The reported exposure rate values include an estimated cosmic ray contribution. Enhanced exposure rates not attributable to natural background were measured over several areas within the survey region. The manmade radionuclides detected in these areas, cesium-137, cobalt-60, and protactinium-234m, were produced by the reactor operations and material processing conducted at the SRS. The radiation levels produced by these nuclides are consistent with those levels measured during previous SRS aerial surveys. Radionuclide assays of soil samples and pressurized ion chamber measurements were obtained at four locations within the survey boundaries

Garcia-Martin, Tomas; Rincon-Arevalo, Pedro; Campos-Martin, Gemma

2013-11-01

We present a new and simple method for carbon nano-onions (CNOs) production which is based on the pyrolysis of Propane. CNOs are originated in a laminar premixed Propane/Oxygen flame of approximately 1.8 of stoichiometric coefficient. The stream of gasses resulting from the combustion drives the carbon particles towards the aluminium surface on which nano-onions are deposited and collected. The structure and size of the deposited carbon onion on the metal wall are characterized by High Resolution Transmission Electron Microscopy technique (HRTEM). The experimental images show the presence of two different types of CNOs. The first particles have diameters in the range of 18-25 nm and the second ones around 10 nm.

An aerial radiological survey was conducted over the Oyster Creek Nuclear Power Plant in Forked River, New Jersey, during the period September 18 through September 24, 1992. The survey was conducted at an altitude of 150 feet (46 meters) over a 26-square-mile (67-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Oyster Creek Nuclear Power plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 4 and 10 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey of the power plant was conducted in August 1969 during its initial startup phase. Exposure rates and radioactive isotopes revealed in both surveys were consistent and within normal terrestrial background levels

This paper reports the activities of the coal type committee in fiscal 1992, and summarizes the main technological achievements. In the Chinese coal liquefaction test, fiscal 1991 has performed liquefaction tests on Fushun coal by using a small continuous testing facility (0.1 t/d) at the Coal Chemistry Research Institute in Beijing. Fiscal 1992 has completed the liquefaction tests on Shengli coal. In October, a liquefaction test was carried out by using Tianzhu coal according to the NEDOL process. This paper reports the result of the liquefaction test on the Shengli coal, and the result of the analysis on the Fushun coal liquefied oil. The coal type selection and investigation having been performed to date reveals close correlation among the maceral composition of coal, coal rank and liquefied oil yield. Coals having good reactivity and suitable for liquefaction are generally suitable also for gasification. In the pretreatment of coal as a gasification material for hydrogen manufacture, a test was performed by using A heavy oil and tar sand bitumen plus A heavy oil as the granulating agents. With Montana coal, the highest de-ashing rate was achieved when the oil was added at 35% by weight. Both of the reaction rate and oil yield were improved. A handling test was carried out up to 72.5 degrees C, wherein Tatung coal presented no problems in both of the discharging and sticking tendencies. (NEDO)

The solubilities of bioactive compound vanillin were measured in various propane-1,2-diol+water cosolvent mixtures at T=(298-318)K and p=0.1 MPa. The experimental solubility of crystalline vanillin was determined and correlated with calculated solubility. The results showed good correlation of experimental solubilities of crystalline vanillin with calculated ones. The mole fraction solubility of crystalline vanillin was recorded highest in pure propane-1,2-diol (7.06×10(-2) at 298 K) and lowest in pure water (1.25×10(-3) at 298 K) over the entire temperature range investigated. Thermodynamic behavior of vanillin in various propane-1,2-diol+water cosolvent mixtures was evaluated by Van't Hoff and Krug analysis. The results showed an endothermic, spontaneous and an entropy-driven dissolution of crystalline vanillin in all propane-1,2-diol+water cosolvent mixtures. Based on solubility data of this work, vanillin has been considered as soluble in water and freely soluble in propane-1,2-diol. Copyright © 2015 Elsevier Ltd. All rights reserved.

Growth potential in gas plant ethane production and the impact on propane import trends

International Nuclear Information System (INIS)

Lippe, D.L.

1996-01-01

In varying degrees in most ethylene plants, ethane and propane are used interchangeably as feedstocks. During the next five years, several new ethylene plants will be built in the Gulf Coast area. Most of these plants will be based on LPG feedstocks and will have some flexibility to operate with ethane and propane feedstocks. The completion of new ethylene plants will increase feedstock demand for ethane by 65--90 Mbpd by 1998 and by an additional 50--80 Mbpd by 2000. Thus, the availability of ethane will have a significant impact on Gulf Coast waterborne propane import requirements. Sustained growth in the gas processing industry's ethane recovery capability will effectively minimize waterborne propane import requirements for the next five to ten years. Petral Worldwide's approach to feedstock supply analysis highlights investment opportunities in domestic supply sources. Projects of these types will also limit a growth dependence on NGL feedstock supplies from politically unstable supply sources in North Africa and the Middle East. This paper examines the potential for growth in the gas processing industry's ethane recovery capability and the impact on Gulf Coast feedstock markets

Survey of reportable incidents in nuclear power plants in Germany in the year 1992

International Nuclear Information System (INIS)

1993-01-01

In 1992, 223 reportable incidents in German nuclear power plant have been reported. There was no radioactivity release exceeding the maximum permissible limits, and there were no hazardous effects on the population or the environment. There was no incident belonging to category S of the official event scale, requiring urgent notification, while there were two incidents requiring immediate notification. All other incidents reported belonged to category N, the lowest on the scale, requiring normal notification. 216 incidents belonged to category 0 of the INES scale, and 7 to INES category 1 (disturbance). The tabulated survey of the report lists the various events and their position on the INES scale. The reportable events have been analysed thoroughly from various viewpoints, but no systematic pattern of weak points could be detected. (orig./HP) [de

World oil flow steady in 1992; stable market ahead for 1993

International Nuclear Information System (INIS)

Beck, R.J.

1993-01-01

World crude oil production in 1992 was virtually unchanged from 1991. Production last year averaged 59.96 million b/d, up only 17,000 b/d from 1991. Substantial production declines in the C.I.S. and U.S. were offset by increases among members of the Organization of Petroleum Exporting Countries and a number of other countries outside the OPEC sphere. Figures from the International Energy Agency (IEA) show world demand for petroleum products moved up 300,000 b/d to 66.9 million b/d. This included an addition to stocks of an estimated 1000,000 b/d. IEA predicts world demand will continue to rise in 1993 and OPEC output will advance to meet this higher level. Even though OPEC production is expected to be up for the year, seasonal swings in demand can cause price fluctuations. The paper describes OPEC production, non-OPEC production, oil prices, the world oil supply, Russian's decline, world demand, and the outlook for 1993

Since 1978, a series of national surveys (Countryside Survey, CS) have been carried out by the Centre for Ecology and Hydrology (CEH) (formerly the Institute of Terrestrial Ecology, ITE) to gather data on the natural environment in Great Britain (GB). As the sampling framework for these surveys is not optimised to yield data on rarer or more localised habitats, a survey was commissioned by the then Department of the Environment (DOE, now the Department for Environment, Food and Rural Affairs, DEFRA) in the 1990s to carry out additional survey work in English landscapes which contained semi-natural habitats that were perceived to be under threat, or which represented areas of concern to the ministry. The landscapes were lowland heath, chalk and limestone (calcareous) grasslands, coasts and uplands. The information recorded allowed an assessment of the extent and quality of a range of habitats defined during the project, which can now be translated into standard UK broad and priority habitat classes. The survey, known as the "Key Habitat Survey", followed a design which was a series of gridded, stratified, randomly selected 1 km squares taken as representative of each of the four landscape types in England, determined from statistical land classification and geological data ("spatial masks"). The definitions of the landscapes are given in the descriptions of the spatial masks, along with definitions of the surveyed habitats. A total of 213 of the 1 km2 square sample sites were surveyed in the summers of 1992 and 1993, with information being collected on vegetation species, land cover, landscape features and land use, applying standardised repeatable methods. The database contributes additional information and value to the long-term monitoring data gathered by the Countryside Survey and provides a valuable baseline against which future ecological changes may be compared, offering the potential for a repeat survey. The data were analysed and described in a series of

The purpose of the New Mexico Environmental Evaluation Group is to conduct an independent technical evaluation of the Waste Isolation Pilot Plant (WIPP) Project to ensure the protection of the public health and safety and the environment. The WIPP Project, located in southeastern New Mexico, is being constructed as a repository for the disposal of transuranic (TRU) radioactive wastes generated by the national defense programs. The Environmental Evaluation Group (EEG) has reviewed the WIPP 1992 Performance Assessment (Sandia WIPP Performance Assessment Department, 1992). Although this performance assessment was released after the October 1992 passage of the WIPP Land Withdrawal Act (PL 102-579), the work preceded the Act. For individual and ground-water protection, calculations have been done for 1000 years post closure, whereas the US Environmental Protection Agency's Standards (40 CFR 191) issued in 1993 require calculations for 10,000 years. The 1992 Performance Assessment continues to assimilate improved understanding of the geology and hydrogeology of the site, and evolving conceptual models of natural barriers. Progress has been made towards assessing WIPP's compliance with the US Environmental Protection Agency's Standards (40 CFR 191). The 1992 Performance Assessment has addressed several items of major concern to EEG, outlined in the July 1992 review of the 1991 performance assessment (Neill et al., 1992). In particular, the authors are pleased that some key results in this performance assessment deal with sensitivity of the calculated complementary cumulative distribution functions (CCDF) to alterative conceptual models proposed by EEG -- that flow in the Culebra be treated as single-porosity fracture-flow; with no sorption retardation unless substantiated by experimental data

FY 1992 task plans for the Hanford Environmental Dose Reconstruction Project

International Nuclear Information System (INIS)

1991-10-01

Phase 1 of the HEDR Project was designed to develop and demonstrate a method for estimating radiation doses people may have received from Hanford Site operations since 1944. The method researchers developed relied on a variety of measured and reconstructed data as input to a modular computer model that generates dose estimates and their uncertainties. As part of Phase 1, researchers used the reconstructed data and computer model to calculate preliminary dose estimates for populations from limited radionuclides, in a limited geographical area and time period. Phase 1 ended in FY 1990. In February 1991, the TSP decided to shift the project planning approach away from phases--which were centered around completion of major portions of technical activities--to individual fiscal years (FYs), which span October of one year through September of the next. Therefore, activities that were previously designated to occur in phases are now designated in an integrated schedule to occur in one or more of the next fiscal years into FY 1995. Task plans are updated every 6 months. In FY 1992, scientists will continue to improve Phase 1 data and models to calculate more accurate and precise dose estimates. The plan for FY 1992 has been prepared based on activities and budgets approved by the Technical Steering Panel (TSP) at its meeting on August 19--20, 1991. The activities can be divided into four categories: (1) model and data evaluation activities, (2) additional dose estimates, (3) model and data development activities, and (4) technical and communication support. 3 figs., 2 tabs

1993-11-01

Environment Ontario's Spills Action Center (SAC) receives and initiates response to spills and other urgent environmental incidents on a 24 h per day basis. The center documented 14,588 occurrence reports in 1992. Two thirds of these involved a range of ministry notification requirements and environmental complaints, while one third involved spills. Information on spills reported in 1992 are summarized. The 5,014 spills reported to SAC in 1992 represent a 5% decrease from 1991. Fewer spills to air accounted for this decrease, while the number of spills to land and water remained unchanged. Oil and fuel spills accounted for 59% of spilled material. Chemical or chemical solutions accounted for ca 15%, wastes or wastewaters 18%, gaseous emissions 6% and unknown for the remainder. Around 20% of spills were less than 10 liters, 57% were less than 100 liters, and 86% were less than 1000 liters. About 28% of the spills had a confirmed environmental impact or adverse affect, two thirds involving soil contamination and around one fifth involving surface water contamination. Twenty-three spills resulted in human health and safety concerns. Around 45% of all spills were completely cleaned up, and an additional 22% were partially cleaned up. Industrial sectors with the largest proportion of reported spills were: transportation, 16%; petroleum, 13%; metallurgical, 6%; general manufacturing, 5%; and chemical, 5%. Public sector spills accounted for 18% of reported spills. Motor vehicles were the largest sources of spills accounting for over 28% of reported spills. 14 figs., 14 tabs

Snake River sockeye salmon Sawtooth Valley project: 1992 Juvenile and Adult Trapping Program

International Nuclear Information System (INIS)

1992-04-01

Sockeye salmon (Oncorhynchus nerka) runs in the Snake River Basin have severely declined. Redfish Lake near Stanley, Idaho is the only lake in the drainage known to still support a run. In 1989, two adults were observed returning to this lake and in 1990, none returned. In the summer of 1991, only four adults returned. If no action is taken, the Snake River sockeye salmon will probably cease to exist. On November 20, 1991, the National Marine Fisheries Service (NMFS) declared the Snake River sockeye salmon ''endangered'' (effective December 20, 1991), pursuant to the Endangered Species Act (ESA) of 1973. In 1991, in response to a request from the Idaho Department of Fish and Game and the Shoshone-Bannock Tribes, the Bonneville Power Administration (BPA) funded efforts to conserve and begin rebuilding the Snake River sockeye salmon run. The initial efforts were focused on Redfish Lake in the Sawtooth Valley of southcentral Idaho. The 1991 measures involved: trapping some of the juvenile outmigrants (O. nerka) from Redfish Lake and rearing them in the Eagle Fish Health Facility (Idaho Department of Fish and Game) near Boise, Idaho; Upgrading of the Eagle Facility where the outmigrants are being reared; and trapping adult Snake River sockeye salmon returning to Redfish Lake and holding and spawning them at the Sawtooth Hatchery near Stanley, Idaho. This Environmental Assessment (EA) evaluates the potential environmental effects of the proposed actions for 1992. It has been prepared to meet the requirements of the National Environmental Policy Act (NEPA) of 1969 and section 7 of the ESA of 1973

Age at marriage, contraceptive use and abortion in Yemen, 1991-1997

Full Text Available This paper attempts to examine the extent of influence of the three components of fertility, age at marriage, extent of modern contraceptive use and the level of abortion on fertility in the Republic of Yemen and to explore the impact of a selected set of demographic and socioeconomic variables on the three fertility components. This study uses data from Demographic and Health Surveys (DHS conducted in Yemen in 1991/1992 and 1997. The results from this study present empirical evidence of an onset of fertility decline in the Republic of Yemen. An important component of this decline is delayed age at marriage. There has been an increase in modem contraceptive use during the last decade. However, these methods are not widely used at early stages of family formation. The most common method of family limitation among women with large families is abortion. There has been very little change if any in the widespread occurrence of abortion during the last decade. There exist significant urban-rural differences in the levels of contraceptive use and abortion. Improvements in women's education and modern sector labor participation are crucial for increasing age at marriage, and level of contraceptive use and for reducing the prevailing level of abortion.

This, Volume 11 of the 1992 Annual Report of ISIS the neutron scattering facility at Rutherford Appleton Laboratory contains the Experimental Reports on those experiments carried out on ISIS in the year ending 31 March 1992. Included are Experimental Reports from work performed on 14 ISIS instruments (13 neutron and one muon beam), and the number and quality of these reports reflects very well upon the standard of experiments performed at the Facility. The continuing increase in productivity of ISIS, which has extended through the initial development stage of the source, demonstrates that much new science continues to be done at ISIS, and that with the development and provision of new instruments, the scientific output of the Facility will continue to show strong growth. These Experimental Reports are intended as interim summaries of the measurements made during an ISIS experiment and as such may not contain the final conclusions of the analysis. They do, however, give a general flavour of the range and type of science performed on each instrument. (author)

Two cases of acute propane/butane poisoning in prison.

Rossi, Riccardo; Suadoni, Fabio; Pieroni, Ludovica; De-Giorgio, Fabio; Lancia, Massimo

2012-05-01

Hydrocarbon inhalation is seldom chosen as a means to commit suicide. This practice is exclusively a prerogative of the prison population; it is, however, only exceptionally found in this environment. The two cases of lethal inhalation of propane/butane gas observed by us over a very short time occurred in this context. Toxicologic analyses were performed by means of gas chromatography (head space) and revealed a propane/butane mixture in all specimens (heart blood, bile, and urine) except vitreous humor. Although fatal arrhythmia posthydrocarbon gas abuse is well known, the concentrations of the two hydrocarbons were sufficient to induce death by asphyxiation and were distributed (fairly) homogeneously in all biological fluids and organs examined, a parameter permitting one to assume that death occurred within a relatively short period of time. The absence of finding in vitreous humor and the trace amount in urine suggests that both men died very quickly. © 2011 American Academy of Forensic Sciences.

The Impact of Survey and Response Modes on Current Smoking Prevalence Estimates Using TUS-CPS: 1992-2003

Directory of Open Access Journals (Sweden)

Julia Soulakova

2009-12-01

Full Text Available This study identified whether survey administration mode (telephone or in-person and respondent type (self or proxy result in discrepant prevalence of current smoking in the adult U.S. population, while controlling for key sociodemographic characteristics and longitudinal changes of smoking prevalence over the 11-year period from 1992-2003. We used a multiple logistic regression analysis with replicate weights to model the current smoking status logit as a function of a number of covariates. The final model included individual- and family-level sociodemographic characteristics, survey attributes, and multiple two-way interactions of survey mode and respondent type with other covariates. The respondent type is a significant predictor of current smoking prevalence and the magnitude of the difference depends on the age, sex, and education of the person whose smoking status is being reported. Furthermore, the survey mode has significant interactions with survey year, sex, and age. We conclude that using an overall unadjusted estimate of the current smoking prevalence may result in underestimating the current smoking rate when conducting proxy or telephone interviews especially for some sub-populations, such as young adults. We propose that estimates could be improved if more detailed information regarding the respondent type and survey administration mode characteristics were considered in addition to commonly used survey year and sociodemographic characteristics. This information is critical given that future surveillance is moving toward more complex designs. Thus, adjustment of estimates should be contemplated when comparing current smoking prevalence results within a given survey series with major changes in methodology over time and between different surveys using various modes and respondent types.

As compared with the past reports, in the report of this year, pages increased and the style changed, but this is due to the change of the method of adopting researches to that throughout one year from fiscal year 1991. So far one page was allotted to every subject, but this limit was relaxed according to the contents. This style is not yet fixed. As well known, discussion is going on about the way the research reactor and the Research Reactor Institute should be. As for this summary report, in order to receive the international evaluation, it was decided to publish the report in English from fiscal year 1992, and the Progress Report on the research by the Institute personnel is included in it. In this report, 98 summaries of the researches using the KUR and 15 summaries of the researches using the KUCA are collected. One summary which was not reported in fiscal year 1990 is added. (K.I.)

Site-specific carbon isotope measurements of organic compounds potentially recover information that is lost in a conventional, ‘bulk’ isotopic analysis. Such measurements are useful because isotopically fractionating processes may have distinct effects at different molecular sites, and thermodynamically equilibrated populations of molecules tend to concentrate heavy isotopes in one molecular site versus another. Most recent studies of site-specific 13C in organics use specialized Nuclear Magnetic Resonance (NMR) techniques or complex chemical degradations prior to mass spectrometric measurements. Herein we present the first application of a new mass spectrometric technique that reconstructs the site-specific carbon isotope composition of propane based on measurements of the 13C/12C ratios of two or more fragment ions that sample different proportions of the terminal and central carbon sites. We apply this method to propane from laboratory experiments and natural gas samples to explore the relationships between site-specific carbon isotope composition, full-molecular δ13C, thermal maturity, and variation in organic matter precursors. Our goal is to advance the understanding of the sources and histories of short-chain alkanes within geologic systems. Our findings suggest that propane varies in its site-specific carbon isotope structure, which is correlated with increasing thermal maturity, first increasing in terminal position δ13C and then increasing in both center and terminal position δ13C. This pattern is observed in both experimental and natural samples, and is plausibly explained by a combination of site-specific, temperature-dependent isotope effects associated with conversion of different precursor molecules (kerogen, bitumen, and/or oil) to propane, differences in site-specific isotopic contents of those precursors, and possibly distillation of reactive components of those precursors with increasing maturity. We hypothesize that the largest changes in

Experimental Investigation into the Combustion Characteristics of Propane Hydrates in Porous Media

Directory of Open Access Journals (Sweden)

Xiang-Ru Chen

2015-02-01

Full Text Available The combustion characteristics of both pure propane hydrates and the mixtures of hydrates and quartz sands were investigated by combustion experiments. The flame propagation, flame appearance, burning time and temperature in different hydrate layers were studied. For pure propane hydrate combustion, the initial flame falls in the “premixed” category. The flame propagates very rapidly, mainly as a result of burnt gas expansion. The flame finally self-extinguishes with some proportion of hydrates remaining unburned. For the hydrate-sand mixture combustion, the flame takes the form of many tiny discontinuous flames appearing and disappearing at different locations. The burn lasts for a much shorter amount of time than pure hydrate combustion. High porosity and high hydrate saturation is beneficial to the combustion. The hydrate combustion is the combustion of propane gas resulting from the dissociation of the hydrates. In both combustion test scenarios, the hydrate-dissociated water plays a key role in the fire extinction, because it is the main resistance that restrains the heat transfer from the flame to the hydrates and that prevents the hydrate-dissociated gas from releasing into the combustion zone.

The United Kingdom Atomic Energy Authority (AEA) is a public corporation set up by the Atomic Energy Authority Act 1954. These accounts comply with the provisions of that Act and directions issued by the Treasury. The Atomic Energy Authority Act 1986 requires AEA to operate from 1 April 1986 as a Trading Fund. Under the trading banner AEA Technology, the group made a further substantial increase in the profit on ordinary activities to Pound 28.1M (1991 Pound 17.7M). The considerable restructuring of the organisation in the past two years contributed to this by delivering cost savings, and the business structure has focused marketing efforts on profitable activities. Turnover has been maintained at last year's level. While long standing nuclear business declined, the group succeeded in increasing United Kingdom private sector business despite the recession. New markets have been developed, and important new business has been won in Europe and the Far East. (Author)

A Study on the Kinetics of Propane-Activated Carbon: Theory and Experiments

KAUST Repository

Ismail, Azhar bin

2013-08-01

Experimental kinetics results of propane in Maxsorb III activated carbon is obtained at temperatures of 10°C and 30°C, and pressures up to 800kPa using a magnetic suspension balance. A multi-gradient linear driving force (LDF) approximation is used for adsorbate uptake as a function of time. The LDF mass-transfer-rate coefficients were thus determined. Using this approach, the experimentally derived LDF coefficients based on independently measured kinetic parameters for propane in the activated-carbon bed agree very well with experimental results. The computational efficiency is gained by adopting this extended LDF model. © (2013) Trans Tech Publications, Switzerland.

The stepwise mechanism of oxidative ammonolysis of propane to acrylonitrile over gallium-antimony oxide catalysts GaSb/sub 19/O/sub x/, GaSb/sub 3/Ni/sub 1.5/0/sub x/, and GaSb/sub 2.5/Ni/sub 1.5/PW/sub 0//sub 0.25/O/sub x/ was studied at 450/sup 0/ and 550/sup 0/C by introducing alternating pulses of 0.5Vertical Bar3< propane/0.6Vertical Bar3< ammonia/helium (to reduce the steady-state catalytic surface) and 0.5Vertical Bar3< propane/0.6Vertical Bar3< ammonia/1.86Vertical Bar3< oxygen/helium mixtures into a fluidized-bed catalytic reactor. Over all the catalysts studied, the rates of acrylonitrile formation during the two types of pulses were very similar, but carbon dioxide was formed much faster during the reducing pulses, particularly at 450/sup 0/C. These findings suggested that acrylonitrile is formed by a stepwise redox mechanism involving consecutive interaction of propane and ammonia with the surface oxygen of the catalysts and oxidation of the reduced catalyst surface by gas-phase oxygen. The formation of carbon dioxide proceeds by both stepwise and associative mechanisms, the latter being more important at higher temperatures. The results are similar to published results for ammoxidation of propylene and olefins.

This paper reports the coal gasification committee and the gasification technology sub-committee in fiscal 1992. The paper summarizes the report mainly on the data distributed at the gasification technology sub-committee meetings in fiscal 1992. In developing the coal utilizing hydrogen manufacturing technology, the trial operation was started on the pilot plant in fiscal 1991, wherein two comprehensive trial operations were carried out on gasification of 10 kg/cm{sup 2} to extract troubles throughout the whole system, smooth temperature rise and pressure rise were performed, and coal and oxygen were supplied into a furnace to have verified ignition of the coal. Furthermore, one trial operation for gasification of 30 kg/cm{sup 2} was executed. Fiscal 1992 will continue the gasification test of 30 kg/cm{sup 2}. In addition, a test on measures to improve efficiency purposed for gasification efficiency enhancement is carried out, and so is a coal type diversification test purposed to expand coal type applicability. A study was performed by using a small device as a pilot plant supporting study. Prototype fabrication, development, and in-plant tests were made on materials for plant devices (refractories and ceramics). The paper also describes the current status of HYCOL pilot plant operation study. Discussions were given also on heat balance of a gasification furnace. (NEDO)

The Second Workshop on Human Chromosome 3 was held on April 4--5, 1991 at Denver, Colorado. There were 43 participants representing 8 nations. The workshop participants reviewed the current state of the chromosome 3 map, both physical and genetic, and prepared lists of markers and cell lines to be made commonly available. These markers and cell lines should be incorporated into the mapping efforts of diverse groups to permit the integration of data and development of consensus maps at future workshops. Region specific efforts were described for sections of the chromosome harboring genes thought to be involved in certain diseases including Von Hippel-Lindau disease, 3p-syndrome, lung cancer and renal cancer. Selected papers have been processed separately for inclusion in the Energy Science and Technology Database.

Differential Thermal Analysis and Dielectric Studies on 2-Methyl-2-Nitro-Propane under High Pressure

Science.gov (United States)

Büsing, D.; Jenau, M.; Reuter, J.; Würflinger, A.; Tamarit, J. Li.

1995-05-01

Differential thermal analysis and dielectric studies under pressures up to 300 MPa and temperatures of about 200 to 350 K have been performed on 2-methyl-2-nitro-propane (TBN). TBN displays an orientationally disordered phase (ODIC), solid I, and two non-plastic phases, solids II and III. The coexistence region of the plastic phase I increases with increasing pressure, whereas the low-temperature phase II apparently vanishes at a triple point I, II, III, above 300 MPa. The static permittivity increases on freezing, characterizing the solid I as an ODIC phase. In the frame of the Kirkwood-Onsager-Fröhlich theory the g-factor is about unity, discounting specific dielectric correlations. The dielectric behaviour of TBN is similar to previously studied related compounds, such as 2-chloro-2-methyl-propane or 2-brome- 2-methyl-propane

The compound oryzanol available in the rice bran (oriza sativa) is well known for its antioxidant activity. Phase equilibrium data involving oryzanol in compressed fluids, hardly found in the literature, are important to provide the basis for the extraction and fractionation processes. In this sense, the aim of this work is to report phase equilibrium measurements for the system (γ-oryzanol + chloroform) in compressed propane. Phase equilibrium experiments were performed using the static synthetic method (cloud points transition data) in a high-pressure variable-volume view cell in the temperature range of 303 K to 353 K, pressures up to 17 MPa, for oryzanol overall mass fractions of 2 wt%, 5 wt% and 10 wt% in (propane + chloroform) mixtures. A complex phase behaviour comprising vapour-liquid, liquid-liquid, vapour-liquid-liquid, solid-liquid, solid-liquid-liquid, solid-liquid-liquid-vapour transitions were visually observed for the system studied.

Possibilities for increasing the efficiency of supported on SiO{sub 2} chromium-oxide catalysts in propane oxidative dehydrogenation in CO{sub 2} presence are investigated: the introduction of Li, Na, K, Ca in catalysts and the addition of O{sub 2} in the reaction mixture. It was been found that the positive role of K - the increase of the selectivity to propene and stability of catalysts at long-duration tests - appeared at the relation of Cr:K=20. It was shown that the presence of little amount of O{sub 2} (2%) in the reaction mixtures of propane and carbon dioxide resulted in the increase of propene yield and catalyst stability. (orig.)

This paper presents the results of the 13th quality control nationwide survey. Of 568 hospitals performing RI in vitro tests as of December 1991, 280 (49.3%) participated in this survey. The following 37 items were examined: ACTH, 17[alpha]-hydroxyprogesterone, [alpha]-fetoprotein, aldosterone, [beta]2-microglobulin, CA 125, CA 15-3, CA 19-9, calcitonin, CEA, cortisol, C-peptide, digoxin, esteradiol, ferritin, free triiodothyronine (T[sub 3]), free thyroxine (T[sub 4]), FSH, gastrin, GH, glucagon, IgE, insulin, LH, PAP, progesterone, prolactin, PTH, somatomedin C, T[sub 3], T[sub 4], T[sub 3] uptake, TBG, testosterone, thyroglobulin, tissue polypeptide antigen, and TSH. Reliability and safety of measurement values were evaluated based on protein components of serum samples, spontaneous reliability test, time-dependent reliability test, repeated freezing-dissolution test, and serial change test after freezing. 'Within kit variation' between facilities was great especially for ACTH, CA 15-3, CA 19-9, free T[sub 4], calcitonin, gastrin, and testosterone, and was favorable for [beta][sub 2]-microglobulin, CA 125, digoxin, cortisol, IgE, T[sub 3], T[sub 4], T[sub 3] uptake, and TBG. It was noted that there was a great difference in measurement values of free T[sub 3] and free-T[sub 4] between RIA kits and non-isotopic kits. (N.K.).

In this paper, a theoretical model is developed to predict the refrigerant flow characteristics in adiabatic capillary tubes using propane/n-butane/iso-butane mixtures as working fluids in a domestic refrigerator. This model is based on the mass, energy and momentum conservation equations for a homogeneous refrigerant flow under different inlet conditions, such as subcooled, saturated and two phase flow. The effects of the inlet pressure (8-16 bar), inlet vapor quality (0.001-15%), inlet subcooling degree (1-15 o C), mass flow rate (1-5 kg/h), propane mass fraction (0.5-0.7), capillary tube inner diameter (0.6-1.0 mm) and the tube surface roughness on the capillary tube length are predicted. The results showed that the present model predicts data that are very close to the available experimental data in the literature with an average error of 2.65%. The pressure of the hydrocarbon mixture (HCM) decreases, while its vapor quality, specific volume and Mach number increase along the capillary tube. Also, the results indicated that the capillary tube length is largely dependent on the capillary tube diameter. Other parameters such as mass flow rate, inlet pressure, subcooling degree (or quality) and relative roughness influence the capillary tube length in that order. The capillary tube length as a function of the significant parameters is presented in equation form. Also, capillary tube selection charts either to predict the mass flow rates of propane/n-butane/iso-butane mixtures through adiabatic capillary tubes or to select the capillary tube size according to the required applications are developed. The comparison between R12, R134a and the hydrocarbon mixture (HCM) of propane/n-butane/iso-butane indicated that for a given mass flow rate, the pressure drop per unit length is about 4.13, 5.0 and 12.0 bar/m for R12, R134a and HCM, respectively. The ratios of the average mass flow rate of the HCM with a propane mass fraction of 0.6 to those of R12 and R134a are about

A Tissue-Equivalent Proportional Counter (TEPC), based on a single GEM foil of standard geometry, has been tested with pure propane gas at low pressure, in order to simulate a tissue site of about 1 µm equivalent size. In this work, the performance of GEM with propane gas at a pressure of 21 and 28 kPa will be presented. The effective gas gain was measured in various conditions using a {sup 244}Cm alpha source. The dependence of effective gain on the electric field strength along the GEM channel and in the drift and induction region was investigated. A maximum effective gain of about 5×10{sup 3} has been reached. Results obtained in pure propane gas are compared with gas gain measurements in gas mixtures commonly employed in microdosimetry, that is propane and methane based Tissue-Equivalent gas mixtures.

Full Text Available Catalytic activity of nano-Au-catalyst(s for the complete propane oxidation was investigated. The results showed that the nature of both Au precursor and support strongly influences catalytic activity of the Au-catalyst(s for the propane oxidation. Oxidation state, size, and dispersion of Au nanoparticles in the Au-catalysts, surface area, crystallinity, phase structure, and redox property of the support are the key aspects for the complete propane oxidation. Among the studied Au-catalysts, the AuHAuCl4-Ce catalyst is found to be the most active catalyst.

Investigation was undertaken to assess the occurrence of zoonotic infection among staff at Auckland Zoological Park, New Zealand, in 1991, 2002 and 2010. Serial cross-sectional health surveys in 1991, 2002 and 2010 comprising a health questionnaire, and serological, immunological and microbiological analysis for a range of potential zoonotic infections were performed. Laboratory results for zoo animals were also reviewed for 2004-2010 to assess the occurrence of potential zoonotic infections. Veterinary clinic, animal handler, grounds, maintenance and administrative staff participated in the surveys, with 49, 42 and 46 participants in the 1991, 2002 and 2010 surveys, respectively (29% of total zoo staff in 2010). A small number of staff reported work-related infections, including erysipelas (1), giardiasis (1) and campylobacteriosis (1). The seroprevalence of antibodies to hepatitis A virus and Toxoplasma gondii closely reflected those in the Auckland community. No carriage of hepatitis B virus (HBV) was detected, and most of those with anti-HBV antibodies had been vaccinated. Few staff had serological evidence of past leptospiral infection. Three veterinary clinic staff had raised Chlamydophila psittaci antibodies, all Auckland Zoo, this was uncommon and risks appear to be adequately managed under current policies and procedures. Nevertheless, ongoing assessment of risk factors is needed as environmental, human and animal disease and management factors change. Policies and procedures should be reviewed periodically in conjunction with disease monitoring results for both animals and staff to minimise zoonotic transmission. © 2012 Blackwell Verlag GmbH.

An evaluation of air quality at two sites in the lower townsite of Fort McMurray, October 1, 1991 to June 30, 1992

Myrick, R.H.

1992-01-01

Air quality data collected at two monitoring locations in Fort McMurray, Alberta, from October 1991 to June 1992 are summarized and evaluated. The data analysis includes a comparison of daily average pollutant concentrations at the two stations, the cumulative frequency distribution of the 1-hour average pollutant concentrations, the frequency of times that air pollution regulations were exceeded, and an analysis of the H 2 S and SO 2 concentrations greater than their respective odor thresholds. It was found that SO 2 and H 2 S showed a greater frequency of high concentrations at the Athabasca River Valley location compared to the downtown location. This is attributed to transportation of those pollutants down the valley during stable meteorological conditions with light northerly winds. H 2 S concentrations greater than the 3.5-ppB odor threshold were also more frequent at the valley location, while SO 2 concentrations were below this threshold during the monitoring period. H 2 S and SO 2 concentrations were found to be much greater during times of odor complaints than average values for the entire monitoring period. The odors which prompt complaints are likely caused by sulfur compounds originating from the oil sands plants to the north of the city. Pollutants such as CO and particulates, produced by urban sources, were generally higher at the downtown monitoring location. It was determined that the valley site was the most suitable location for monitoring air pollutants transported into the lower townsite of Fort McMurray from the oil sands facilities. 11 refs., 11 figs., 8 tabs

The short-chain, non-methane hydrocarbons propane and butane can contribute significantly to the carbon and sulfur cycles in marine environments affected by oil or natural gas seepage. In the present study, we enriched and identified novel propane and butane-degrading sulfate reducers from marine oil and gas cold seeps in the Gulf of Mexico and Hydrate Ridge. The enrichment cultures obtained were able to degrade simultaneously propane and butane, but not other gaseous alkanes. They were cold-adapted, showing highest sulfate-reduction rates between 16 and 20 °C. Analysis of 16S rRNA gene libraries, followed by whole-cell hybridizations with sequence-specific oligonucleotide probes showed that each enrichment culture was dominated by a unique phylotype affiliated with the Desulfosarcina-Desulfococcus cluster within the Deltaproteobacteria. These phylotypes formed a distinct phylogenetic cluster of propane and butane degraders, including sequences from environments associated with hydrocarbon seeps. Incubations with (13)C-labeled substrates, hybridizations with sequence-specific probes and nanoSIMS analyses showed that cells of the dominant phylotypes were the first to become enriched in (13)C, demonstrating that they were directly involved in hydrocarbon degradation. Furthermore, using the nanoSIMS data, carbon assimilation rates were calculated for the dominant cells in each enrichment culture.

The dissociation kinetics of mixed gas hydrates that contain propane as a guest molecule have been investigated. The mixed gas hydrates used in this work were artificially prepared using the binary gas mixture of methane-propane and the ternary gas mixture of methane-ethane-propane. The crystal structures and the guest compositions of the mixed hydrates were clearly identified by using Raman spectroscopy and gas chromatography. The dissociation rates of the gas hydrates observed under several isothermal and isobaric conditions were discussed with an analytical model. The isobaric conditions were achieved by pressurizing with mixed gases using buffer cylinders, which had similar compositions to those of the initial gases used for synthesizing each hydrate sample. Interestingly, the calculated result agreed well with the experimentally observed results only when the composition of the vapor phase was assumed to be identical with that of the hydrate phase instead of the bulk (equilibrium) gas composition

Precipitation totals of 245 and 210 mm were measured at UE-29 UZN {number_sign}91 and UE-29 UZN {number_sign}92 respectively, during the 1992 water year, October 1, 1991 to September 30, 1992. Approximately ninety percent of the precipitation fell during the period December 27 to April 2. Localized streamflow was generated in the Fortymile Wash drainage basin during the February 12-15, 1992 and March 31, 1992 precipitation, and infiltrated into the streambed materials. The streamflow went across the UE-29 UZN {number_sign}91 neutron-access borehole location and within several meters of the UE-29 UZN {number_sign}92 location. Neutron logging in these boreholes showed increases in the volumetric water content of the unsaturated alluvium and indicated streamflow infiltrated to a depth of approximately 5 meters. The volumetric water content in the upper 5 meters then gradually decreased during the remaining part of the water year. Ground-water levels rose over one meter in wells UE-29 a{number_sign}1 and UE-29 a{number_sign}2, and one-half meter in neutron-access borehole LJE-29 UZN {number_sign}91 following the streamflows. Water level declines of 0.5 meter in UE-29 a{number_sign}1 and rises of 0.2 meter in UE-29 a{number_sign}2 and 0.1 meter in UE-29 UZN {number_sign}91 coincided with a June 29, 1992 earthquake at the Little Skull Mountain, located approximately 27 kilometers southeast of the wells.

This work reports phase equilibrium experimental results for heavy petroleum fractions in pure propane and n-butane as primary solvents and using methanol as co-solvent. Three kinds of oils were investigated from Marlim petroleum: a relatively light fraction coming from the first distillation of crude petroleum at atmospheric pressure (GOP - heavy gas oil of petroleum), the residue of such distillation (RAT) and the crude petroleum sample. Phase equilibrium measurements were performed in a high-pressure, variable-volume view cell, following the static synthetic method, over the temperature range of 323 K to 393 K, pressures up to 10 MPa and overall compositions of heavy component varying from 1 wt% to 40 wt%. Transition pressures for low methanol and oil concentrations were very close for GOP, RAT, and crude Marlim when using propane as the primary solvent. Close to propane critical temperature, two and three-phase transitions were observed for GOP and Marlim when methanol was increased. When n-butane was used as primary solvent, all transitions observed were of (vapour + liquid) type with transition pressure values smaller than those obtained for propane.

Feast or famine: 1992 spot market review

International Nuclear Information System (INIS)

Anon.

1993-01-01

There was nothing temperate about the uranium spot market in 1992. It was a year of extremes. Demand took off at a brisk pace early in the year as utilities, enticed by low U3O8 prices and interest rates, stepped up their discretionary purchases. With the NUKEM price range sinking to an all-time low of US$6.75-7.70 in November 1991, utilities reckoned that prices had bottomed out and decided to buy and hold material. Indeed, the upper end of NUKEM's range remained below $8.00 per lb for much of the first half of 1992. The main cause of low prices was the flood of imports from the crumbling Soviet Union and its successor, the Commonwealth of Independent States [CIS]. The CIS republics quickly embraced a free-market philosophy to boost their faltering economies, and several hoped to use uranium as a source of badly-needed hard currency. But they were about to get a harsh introduction to capitalism. It came in the form of government intervention, in both the US and Europe. In May, the US Department of Commerce made its preliminary determination that the uranium-producing republics of the CIS were selling material in the US at less than fair market value. The antidumping case was eventually settled in October when the CIS republics [Russia, Ukraine, Uzbekistan, Kazakhstan, Tajikistan and Kyrgyzstan] signed suspension agreements subjecting CIS origin uranium to price and quantity quotas in the US

The nature of hydrocarbon activation in oxidative ammonolysis of propane to acrylonitrile over a gallium-antimony oxide catalyst GaSbNiPOx (1:3:1.5:1 atomic ratios of the elements) was studied by comparing the rate of this reaction at 550/sup 0/C and 5Vertical Bar3< by vol propane/6Vertical Bar3< ammonia/18.6Vertical Bar3< oxygen/70.4Vertical Bar3< helium reactant mixture with that of isobutane ammoxidation to methacrylonitrile under the same conditions, at low (Vertical Bar3; 20Vertical Bar3<) conversions that prevent secondary oxidation of the products. Both the over-all hydrocarbon conversion rate and that of nitrile formation were higher for propane, suggesting that the reactions proceed via the respective carbanions (probably primary carbanions), rather than carbocations or uncharged radicals.

Effective chromium and gallium oxides supported catalysts were prepared and tested in longduration experiments for propane dehydrogenation in the presence of CO{sub 2}. The optimal concentrations of active metals were found. It was shown that the activity, selectivity and stability of chromium oxides catalysts were higher than these parameters for gallium ones. Mechanism of propane oxidative dehydrogenation was studied over both catalysts using unstationary and spectroscopic methods. The employment of these methods allowed to establish the differences in process mechanism. It was shown that surface hydroxides took participation in propene formation over Cr-catalysts and hydrides - over Ga-ones. Propane and carbon dioxide participated in the reaction from the adsorbed state over both catalysts but they were differed by the adsorption capacity of the reaction components: CO2 was tied more firmly than C{sub 3}H{sub 6} over both catalysts, CO{sub 2} and C{sub 3}H{sub 6} were tied more strongly with Cr-catalysts than with Ga-ones. It was shown that CO{sub 2} took active participation in reverse watergas shift reaction and in oxidation of catalyst surface over chromium oxides catalysts. The main role of CO{sub 2} in propane dehydrogenation over gallium catalysts consisted in a decrease of coke formation. Step-schemes of propene and cracking products formation were proposed on the basis of literature and obtained data: via the redox mechanism over Cr-catalysts and through a heterolytic dissociation reaction pathway over Ga-ones.

A critical review of the occurrence of 3-chloro-propane-1,2-diol (3-MCPD) in foods not known to contain hydrolysed vegetable proteins is presented. The review covers the properties and chemistry of 3-MCPD and the current methods of analysis in foodstuffs. The results of UK surveys of 3-MCPD occurrence in both retail foods and commercial food ingredients are discussed with particular reference to cereal, meat and dairy products. The possible mechanisms for the formation and decay of 3-MCPD in foods are suggested. The review does not cover the detailed toxicology of 3-MCPD and its occurrence in hydrolysed vegetable proteins, which have been considered elsewhere, nor possible issues such as in-vivo formation.

The members of CRPA take part also in international and European congresses. In this paper we analyse the participation of Croatian authors in national symposia and international congresses in the period from 1992 to 2002. The number of papers in proceedings of the national symposia is rather constant (about 60), while at the First symposium in 1992 it was slightly higher (68). The fraction of papers by Croatian authors was also the highest at the First Symposium (∼ 90%), while at the following symposia it varied between 70% and 80%. Although the analysed period is rather short, one can see slight changes in the research topics. Radioecology, including radon and related topics, was the most frequent research area (36% of all papers) at the national CRPA symposia 1992-1998, followed by the biological effects of radiation and radiation protection in medicine (24%), dosimetry, methods and instrumentation (21%), general topics (11%) and radioactive waste (7%). The distribution of topics at the Fifth symposium is: 27% radioecology and radon, 30% biological and medical topics, as well as professional and public exposure, 24% dosimetry, 14% general topics and 5% non-ionising radiations. In this Symposium we have separate sections for non-ionising radiations and public exposure, although several papers on these subjects were presented already at the previous symposia. (author)

Hydrogen Safety Issues Compared to Safety Issues with Methane and Propane

Green, Michael A.

2005-01-01

The hydrogen economy is not possible if the safety standards currently applied to liquid hydrogen and hydrogen gas by many laboratories are applied to devices that use either liquid or gaseous hydrogen. Methane and propane are commonly used by ordinary people without the special training. This report asks, 'How is hydrogen different from flammable gasses that are commonly being used all over the world?' This report compares the properties of hydrogen, methane and propane and how these properties may relate to safety when they are used in both the liquid and gaseous state. Through such an analysis, sensible safety standards for the large-scale (or even small-scale) use of liquid and gaseous hydrogen systems can be developed. This paper is meant to promote discussion of issues related to hydrogen safety so that engineers designing equipment can factor sensible safety standards into their designs

Quantitative surveys of the intertidal macrobiota were conducted between 1991 and 1995 in the Saudi Arabian Gulf along permanent transect lines (PTLs). These were established within the area impacted between Ras az-Zaur and Abu Ali as a result of the 1991 Gulf War, which now forms the Jubail Wildlife Sanctuary, and at control unpolluted sites to the south of the region. Oil moved rapidly off the lower shore and became impacted along the top of all shores within the study region. During the study period this oil weathered and has largely disappeared from rocky shores and decreased in extent in soft sediment shores. By December 1991 between 50 and 100% mortality of biota had occurred on the upper shore as a result of pollution, but by 1995 on the lower shore species diversity was similar to that found on unpolluted shores, and in the upper eulittoral ranged from normal to 71% of that found on control shores. Recovery rates for Saudi Arabia shores, although tentative for upper shore marshes, are within the time scale for shores worldwide, but longer than for subtropical shores elsewhere. (author)

As a part of the survey of geothermal development promotion in FY 1992, chemical/isotopic analysis of fumarolic gas in the Yoshioka district was made to elucidate the underground geothermal structure in the west area of Mt. Aso in Kumamoto Prefecture. Items for analysis of fumarolic gas were 16 items including the temperature, concentration of non-condensable gas, CO2, H2O, CH{sub 4}, {delta}D(CH{sub 4}) and {delta}{sup 13}C(CO2). Items for analysis of condensed water were 9 items including pH, Na, NH{sub 4}, {delta}D(H2O) and {delta}{sup 18}O. As a result of the analysis, the main component of non-condensable gas of fumarolic gas was CO2, and the composition was similar to that of the fumarolic gas in the Yunoya/Tarutama district in the periphery. It was presumed that the origin and formation mechanism of fumarolic gas were also similar to those in the Yunoya/Tarutama district. It was presumed that the deep geothermal reservoir which is the source of vapor/gas generation was composed of the neutral or alkalescent geothermal water, and a possibility that the reservoir is connected with the deep geothermal reservoir in the Yunoya district was presumed from a viewpoint of geographical location.

Distribution and origin of dissolved methane, ethane and propane in shallow groundwater of Lower Saxony, Germany

International Nuclear Information System (INIS)

Schloemer, S.; Elbracht, J.; Blumenberg, M.; Illing, C.J.

2016-01-01

More than 90% of Germany's domestic natural gas production and reserves are located in Lower Saxony, North Germany. Recently, research has been intensified with respect to unconventional shale gas, revealing a large additional resource potential in northern Germany. However, many concerns arise within the general public and government/political institutions over potential groundwater contamination from additional gas wells through hydraulic fracturing operations. In order to determine the naturally occurring background methane concentrations, ∼1000 groundwater wells, covering ∼48 000 km 2 , have been sampled and subsequently analyzed for dissolved methane, ethane and propane and the isotopic composition of methane (δ 13 C). Dissolved methane concentrations cover a range of ∼7 orders of magnitude between the limit of quantification at ∼20 nl/l and 60 ml/l. The majority of groundwater wells exhibit low concentrations (<1 μl/l), a small number of samples (65) reveal concentration in the range >10 ml/l. In 27% of all samples ethane and in 8% ethane and propane was detected. The median concentration of both components is generally very low (ethane 50 nl/l, propane 23 nl/l). Concentrations reveal a bimodal distribution of the dissolved gas, which might mirror a regional trend due to different hydrogeological settings. The isotopic composition of methane is normally distributed (mean ∼ −70‰ vs PDB), but shows a large variation between −110‰ and +20‰. Samples with δ 13 C values lower than −55‰ vs PDB (66%) are indicative for methanogenic biogenic processes. 5% of the samples are unusually enriched in 13 C (≥25‰ vs PDB) and can best be explained by microbial methane oxidation. According to a standard diagnostic diagram based on methane δ 13 C values and the ratio of methane over the sum over ethane plus propane (“Bernard”-diagram) less than 4% of the samples plot into the diagnostic field of typical thermogenic natural

Analysis of tank safety with propane-butane on LPG distribution station

Directory of Open Access Journals (Sweden)

Krzysiak Zbigniew

2017-12-01

Full Text Available An analysis of the risk of failure in the safety valve – tank with propane-butane (LPG system has been conducted. An uncontrolled outflow of liquid LPG, caused by a failure of the above mentioned system has been considered as a threat. The main research goal of the study is the hazardous analysis of propane-butane gas outflow for the safety valve – LPG tank system. The additional goal is the development of an useful method to fast identify the hazard of a mismatched safety valve. The results of the research analysis have confirmed that safety valves are basic protection of the installation (tank against failures that can lead to loss of life, material damage and further undesired costs of their unreliability. That is why a new, professional computer program has been created that allows for the selection of safety valves or for the verification of a safety valve selection in installations where any technical or technological changes have been made.

The aqueous alkaline reaction of 1,3.bis(4.cyanopyridinium)propane dibromide, a reactant constituted of two pyridinium rings linked by a three.methylene bridge, generates a novel compound, 1-(4-cyano-2-oxo-1,2-dihydro-1-pyridyl)-3-(4-cyano-1,2-dihydro-1-pyridyl) propane. The reaction pathway is attributed to the proximity of the OH. ion inserted between two pyridinium moieties, which occurs only in bis(pyridinium) derivatives connected by short methylene spacers, where charge-conformational effects are important.

2015-02-01

We examined smoking cessation rate by education and determined how much of the difference can be attributed to the rate of quit attempts and how much to the success of these attempts. We analyzed data from the National Health Interview Survey (NHIS, 1991-2010) and the Tobacco Use Supplement to the Current Population Survey (TUS-CPS, 1992-2011). Smokers (≥ 25 years) were divided into lower- and higher-education groups (≤ 12 years and >12 years). A significant difference in cessation rate between the lower- and the higher-education groups persisted over the last 2 decades. On average, the annual cessation rate for the former was about two thirds that of the latter (3.5% vs 5.2%; Peducation group have consistently lagged behind their higher-education counterparts in quitting. In addition to the usual concern about improving their success in quitting, tobacco control programs need to find ways to increase quit attempts in this group.

2010-01-01

Mixed metal oxide catalysts based on Mo-V have been known as the most active and selective in the ammoxidation of propane to ACN. A series of MoVCeZr (5 % wt/ wt) supported with MOR, TiO 2 and MgO have been prepared by incipient wetness impregnation method for propane ammoxidation reaction to ACN. The catalyst was calcined in a two step calcination process in static air between 350 - 600 degree Celsius for 10 hour. The surface area and pore size of these catalysts were measured using physical adsorption of nitrogen following Brunauer, Emmet and Teller (BET) equation. The textural and morphological of these catalysts were determined using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). The activities of all catalysts were tested using a fixed-bed reactor with online gas chromatography (GC) at 420 degree Celsius and atmospheric pressure in the presence of 0.5 ml catalyst with composition consisting of 5.8:7:17.4 (propane: ammonia: air) and helium as carrier to give a total flow of 120 ml. Result shows that MoVCeZr support gives a better conversion due to the surface area and pore size characteristic of the catalyst. (author)

[The population census in Nigeria 1991: geographical aspects of a political poker game].

Science.gov (United States)

Fricke, W; Malchau, G

1994-01-01

The population of Nigeria has been estimated at more than 100 million by various sources. The UN in 1987 estimated it at 87 million, the World Bank at 106.2 million, and the Nigerian National Population Commission at 112.3 million. However, the 1991 census, which was carefully conducted, came up with only 87.5 million, whereas according to the World Bank the number should have exceeded 120 million. The discrepancy of 30 million provoked strong reaction among politicians in the country. 5-year average growth rates between 1970 and 1990 indicated an increase from 26.6% to 37.9%; therefore, the population during the 28-year period from 1963 and 1991 must have approximated 100 million. The figure of 112.3 million would require a growth rate of 34.9%, which was plausible from the early 1970s. The results of the 1991 census have pointed to an enigmatic curiosity: was it an accident that the North has registered the highest annual growth rates dating back to 1963, or even 1952? The political infighting and series of coups d'etat by generals may also be correlated to this numerical distortion, since all these generals were Northerners. An accurate analysis was not possible because of the paucity of data. The census of 1991 has not been fully disclosed until the present time [August 1994], strengthening the case of the skeptics, although the full publication of the figures has to do with the political situation in Nigeria. The democratization process was halted after June 1992, especially after the invalidation of the results of the presidential election and the seizing of power by General Abacha. In the event that a democratic government arises, perhaps the figures of the 1991 census will be published, which could also explain the lower growth rate of the economic centers in the Southwest and the Southeast. Nigeria sorely needs more reliable census data for planning because of a one-sided export structure (95% of foreign currency is earned from oil), neglected agriculture

Support for smoke-free restaurants among Massachusetts adults, 1992-1999.

Science.gov (United States)

Brooks, D R; Mucci, L A

2001-02-01

The authors examined trends and predictors of public support for smoke-free restaurants in Massachusetts. Since 1992, the Massachusetts Behavioral Risk Factor Surveillance System has asked survey respondents about their attitudes toward smoking in restaurants. Analyses using data from 1992 to 1999 characterized changes over time in support for smoke-free restaurants and the role of demographic and smoking-related factors in predicting support. During 1992 to 1999, the rate of support for smoke-free restaurants increased from 37.5% to 59.8%, with similar increases among current, former, and never smokers. After adjustment for smoking status, support was associated with socioeconomic characteristics, race/ethnicity, and household smoking rules. Among current smokers, lighter smokers and those who were trying to quit were more likely to endorse smoke-free restaurants. There has been a substantial increase in support for smoke-free restaurants among both smokers and nonsmokers in Massachusetts.

Research of the Office of the Supervising Scientist (OSS) is now tending to concentrate more on the problems that will arise with the decommissioning and rehabilitation of the mine sites, and in providing the knowledge that will enable the very stringent rehabilitation goal and objectives for the Ranger mine site that have been established by the Commonwealth and Northern Territory Governments, to be achieved. Since rehabilitation must be designed to achieve objectives, the success of which will not be known for many decades in the case of revegetation, and many hundreds of years in the case of tailings containment, the science underlying the engineering designs must be sufficiently secure to give confidence that those objectives will be achieved. The current OSS research program, presented in the Annual Report modified as necessary as developments unfold, provides a sound scientific base. Whilst the precise nature of the future development of the Ranger site is not known, the Supervising Scientist is confident, given the continued existence of the OSS with its research base in the Alligator Rivers Research Institute, that the knowledge will be available to ensure that the No. 3 ore body and the Jabiluka resource can be developed without damage to the ecosystems of Kakadu National Park. 16 tabs., 22 figs

Highlights: • Speed of sound measurements were made in aliphatic alcohols and alkanediols. • Speeds of sound were measured in a wide temperature and pressure range. • A pulse-echo method with a double path type sensor operating at 8 MHz was employed. • A double polynomial equation was used to fit the experimental speed of sound data. • The accurate results were compared with available literature sources. - Abstract: Speeds of sound have been measured in three saturated aliphatic alcohols (propan-2-ol, butan-2-ol, and 2-methylpropan-1-ol) and three alkanediols (ethane-1,2-diol, propane-1,2- and -1,3-diol) in the temperature range from (253.15 to 353.15) K and pressures up to 30 MPa by use of a pulse-echo method with a double path type sensor operating at 8 MHz. The expanded overall uncertainties (k = 2) in the speed of sound measurements are estimated to be 0.013% for propan-2-ol, 0.019% for butan-2-ol, 0.01% for 2-methylpropan-1-ol, 0.009% for ethane-1,2-diol, 0.02% for propane-1,2-diol, and 0.07% for propane-1,3-diol. Experimental speeds of sound data were correlated with the temperature and pressure with an empirical double polynomial equation. Our results were also compared with the available literature data and a satisfactory agreement was found.

The aim of our survey was to record the experiences of hospitalised patients with respiratory diseases in order to create a more patient-friendly department. Our study included 609 patients (response rate 70%) with a median age of 64 years (range 13-91) who were discharged from the Department of Thoracic Medicine, Haukeland University Hospital in October 1991, 1992, 1994, 1995 and 1996. 268 patients had obstructive lung disease, 82 had lung cancer. They answered a questionnaire with 24 questions. Patient reception to the ward and staff knowledge of the patients' illnesses, were for the physicians rated as good or better by 92% and 79% and for the nurses by 94% and 70% respectively. 16% of the patients experienced insecurity, 17% anxiety, 12% helplessness, 9% loneliness and 12% little say in the decision making process. Trend factors for these emotional experiences were female sex, old age, obstructive lung disease and long stay in hospital. Patients aged 50 to 69 years and patients with lung cancer had the lowest rate of negative emotional experiences. Despite staff awareness of the prevalence and of the patients' emotional experiences and the risk factors involved, there was no clear reduction of negative experiences in the later surveys compared to the first survey. Patients in a university hospital with respiratory diseases showed unchanged experiences of health care and personal emotions in repeated surveys over a period of five years.

Eickhoff-Shemek, J M; Ryan, K F

1995-01-01

The purpose of this study was to compare the results from a survey of Omaha worksite health promotion activities with the results of a 1992 national survey. Comparisons were made on: (1) the kinds of health promotion activities offered, (2) progress toward the Healthy People 2000 worksite objectives, (3) types of program intervention offered, and (4) administrative factors. A one-time, written, mail-out/mail-back survey design was used. The study took place in Omaha, Nebraska. All area public and private worksites with 250 or more employees were sent surveys. Individuals who were preselected and identified as the best qualified within the company completed the survey instrument. Of the 176 worksites surveyed, 86 completed the survey (49%). Descriptive statistics (percentages) were used to compare the two surveys on kinds of programs offered, progress toward Healthy People 2000 related to worksite health promotion, the types of program intervention offered, and administrative factors. Generally, a greater percentage of respondent worksites from the national survey are offering more health promotion activities and have made more progress toward the Healthy People 2000 worksite objectives than the Omaha worksites. Results from both surveys showed that low levels of intervention are more prevalent than high levels of intervention, and that health promotion activities in most worksites are coordinated by human resources departments and not by someone professionally prepared in health education. Traditionally, major goals of worksite health promotion programs have focused on important organizational outcomes such as improved productivity/morale, reduction in absenteeism, and health care cost-containment. It is important to recognize, however, that low levels of intervention have less impact than more intensive programs on these desired outcomes. Future goals for local and national worksite health promotion programs may need to encourage implementation of more intensive

Enhancing aerobic biodegradation of 1,2-dibromoethane in groundwater using ethane or propane and inorganic nutrients.

Science.gov (United States)

Hatzinger, Paul B; Streger, Sheryl H; Begley, James F

2015-01-01

1,2-Dibromoethane (ethylene dibromide; EDB) is a probable human carcinogen that was previously used as both a soil fumigant and a scavenger in leaded gasoline. EDB has been observed to persist in soils and groundwater, particularly under oxic conditions. The objective of this study was to evaluate options to enhance the aerobic degradation of EDB in groundwater, with a particular focus on possible in situ remediation strategies. Propane gas and ethane gas were observed to significantly stimulate the biodegradation of EDB in microcosms constructed with aquifer solids and groundwater from the FS-12 EDB plume at Joint Base Cape Cod (Cape Cod, MA), but only after inorganic nutrients were added. Ethene gas was also effective, but rates were appreciably slower than for ethane and propane. EDB was reduced to ethane gas and inorganic nutrients. An enrichment culture (BE-3R) that grew on ethane or propane gas but not EDB was obtained from the site materials. The degradation of EDB by this culture was inhibited by acetylene gas, suggesting that degradation is catalyzed by a monooxygenase enzyme. The BE-3R culture was also observed to biodegrade 1,2-dichloroethane (DCA), a compound commonly used in conjunction with EDB as a lead scavenger in gasoline. The data suggest that addition of ethane or propane gas with inorganic nutrients may be a viable option to enhance degradation of EDB in groundwater aquifers to below current state or federal MCL values.

The oxidative dehydrogenation (ODH) of light alkanes is an alternative way for the production of olefins. A wide variety of catalytic systems has been investigated. Vanadium oxide based catalysts were described in the literature as effective catalysts for the ODH of propane. The catalytic activity and selectivity depend on the kind of support material, the kind of dopants and the formation of complex metal oxide phases. In recent papers it was claimed that both orthovanadate and/or pyrovanadate species are selective for the ODH of propane. Niobia based materials were investigated as catalysts for acidic and selective oxidation type reactions. In the ODH of propane niobia exhibited a high selectivity to propene but the conversion of propane was low. V{sub 2}O{sub 5}-Nb{sub 2}O{sub 5} catalysts proved to be catalytically active and selective and showed no formation of oxygenates. In the present study the influence of the niobia dopant of the catalytic properties of V{sub 2}O{sub 5}-ZrO{sub 2} catalysts in the ODH of propane was examined. The structural and textural properties of the catalysts were investigated using several methods. (orig.)

The US Department of Energy has established the Tank Waste Remediation System (TWRS) to manage and dispose of radioactive wastes stored at the Hanford Site. Within this program are evaluations of pretreatment system alternatives through literature reviews. The information in this report was collected as part of this project at Pacific Northwest Laboratory. A preliminary survey of literature on separations recently entered into the Hanford electronic databases (1992--1993) that have the potential for pretreatment of Hanford tank waste was conducted. Separation processes that can assist in the removal of actinides (uranium, plutonium, americium), lanthanides, barium, 137 Cs, 90 Sr, 129 I, 63 Ni, and 99 Tc were evaluated. Separation processes of interest were identified through literature searches, journal reviews, and participation in separation technology conferences. This report contains brief descriptions of the potential separation processes, the extent and/or selectivity of the separation, the experimental conditions, and observations. Information was collected on both national and international separation studies to provide a global perspective on recent research efforts

Uranium in the new world market: a statistical update of supply and demand 1991-2010

International Nuclear Information System (INIS)

1992-10-01

The Uranium Institute first issued a statistical update to its biennial report on the uranium market in 1990. It was felt then that certain parameters in the supply-demand equation had changed significantly and that therefore the main data should be reviewed. Since publication of the 1991 report, Uranium in the New World Market, the changes have not been as far-reaching, nevertheless some trends have been confirmed, while others have been reversed. More information has also come to light from Eastern Europe, Commonwealth of Independent States (CIS) and China. Unforeseen developments since the 1991 report include the major revision of Ontario Hydro's plans which resulted in the deferral of additional power plants, the decision to complete the Philippine's mothballed reactor, the announcement of North Korea's nuclear programme and most recently the decision to suspend construction of Cuba's nuclear power plant and to put its nuclear programme on hold indefinitely. In order to evaluate the potential impact of these and other events on the uranium market, key statistical data have been reviewed. The data were collected in early 1992. The main changes since the 1991 report are summarized. The revisions have resulted in changes in the forecasts; the forecast nuclear generating capacity has been revised downwards, the forecast reactor requirements for western countries in 2000 have increased slightly whereas for 2000 there is almost no change.

Climatological relevance of major USA weather losses during 1991-1994

Changnon, David; Changnon, Stanley A.

1998-01-01

Two insurance indices, which integrate storm types with their losses from 1948 to 1994, were examined to assess the frequency and intensity of damaging weather in the USA from 1991 to 1994. These indices adjust for changing socio-economic conditions, allowing meaningful temporal assessment of 1991-1994 conditions against those in earlier years.Catastrophes, as defined by property loss insurers, were assessed for two groups, those 707 storms with insured losses between 10 and 100 million and those 189 with greater than 100 million. Both categories experienced their greatest frequency and caused more loss during the 1991-1994 period than in any prior period. However, the temporal behaviour of annual frequency and losses for both categories were very different, with steady increases found for the 10 to 100 million catastrophes, while the number of >100 million catastrophes exhibited a high-low-high distribution and the annual cost distribution was flat with a few isolated peaks. For both categories the temporal behaviour of storm intensity was similar, with moderate intensities found in the recent period and the highest intensities in the 1950s. The crop-hail losses were high in 1992-1994, and the annual loss costs for the 1948-1994 period had a U-shaped time distribution similar to that of the >100 million catastrophes.Weather conditions (USA mean temperature and surface cyclone frequency) were found to largely define: (i) when major, highly expensive weather events occur (and their annual losses), and (ii) how intense catastrophic storm conditions and crop-damaging hailstorms are during each year. Conversely, the shifting target (population as an index) for damaging (non-hurricane) storms across the USA is the major factor in creating storms with losses reaching into the low (10 million) to moderate ($100 million) range.

Performance of 6FDA–6FpDA polyimide for propylene/propane separations

KAUST Repository

Das, Mita

2010-12-01

This work addresses the challenges faced by previous researchers with 6FDA-6FpDA polyimide for propylene/propane separations due to plasticization. A study of film annealing temperature is reported to optimize plasticization suppression in elevated temperature permeation on properly annealed dense films made with high molecular weight polymer. A detailed analysis of pure and mixed gas results using different permeability models is shown in this work. The annealing effects in terms of plasticization suppression and permeability and selectivity changes are discussed in detail. According to our best knowledge, this is for the first time plasticization suppression for propylene/propane has been reported with any polyimide dense film membrane. Results of pure gas sorption experiments using a pressure decay method with un-annealed and annealed films are discussed and used to analyze the permeation data using the dual-mode model. Mixed gas permeation results also are explained with dual mode and bulk flow transport models. © 2010 Elsevier B.V.

The Grays Harbor Navigation Improvement Project was initiated to improve navigation by widening and deepening the federal channel at Grays Harbor. Dredged-material disposal sites were selected after an extensive review process that included inter-agency agreements, biological surveys, other laboratory and field studies, and preparation of environmental impact statements The Southwest Site, was designated to receive materials dredged during annual maintenance dredging as well as the initial construction phase of the project. The Southwest Site was located, and the disposal operations designed, primarily to avoid impacts to Dungeness crab. The Final Environmental Impact Statement Supplement for the project incorporated a Site Monitoring Plan in which a tiered approach to disposal site monitoring was recommended. Under Tier I of the Site Monitoring Plan, Dungeness crab densities are monitored to confirm that large aggregations of newly settled Dungeness crab have not moved onto the Southwest Site. Tier 2 entails an increased sampling effort to determine whether a change in disposal operations is needed. Four epibenthic surveys using beam trawls were conducted in 1990, 1991, and 1992 at the Southwest Site and North Reference area, where high crab concentrations were found in the spring of 1985. Survey results during these three years prompted no Tier 2 activities. Epibenthic surveys were also conducted at two nearshore sites where construction of sediment berms has been proposed. This work is summarized in an appendix to this report.

1993-03-25

By Congress in 1977 as an independent entity within the Department of Energy, the Energy Information Administration (EIA) is the principal and authoritative source of comprehensive energy data for the Congress, the Federal Government, the States, and the public. During 1992, EIA provided information and analysis in response to many energy-related issues and events, including Hurricane Andrew. In addition, EIA made substantial strides in a number of critical special projects, most notably development of the National Energy Modeling System, preparation of National Petroleum Council studies on petroleum refining and natural gas, and establishment of oxygenate data program mandated by the Clean Air Act Amendments of 1990. EIA also took advantage of new opportunities for international consultations and energy information exchanges. This report to Congress contains energy-related information on the following: petroleum; natural gas; integrated analysis and forecasting; electricity; coal; energy markets and end use, nuclear, statistical standards, and information services. The appendices include: data collection surveys of the Energy Information Administration; Analytic models of the Energy Information Administration; EIA publication -- EIA products available on diskette; and Major laws affecting EIA, 1974-1992.

This report documents the results of a survey of domestic research on superconducting magnetic energy storage (SMES) undertaken with the support of the Oak Ridge National Laboratory (ORNL) Superconductivity Pilot Center. Each survey entry includes the following: Name, address, and other telephone and facsimile numbers of the principal investigator and other staff members; funding for fiscal year 1991, 1992, 1993; brief descriptions of the program, the technical progress to date, and the expected technical progress; a note on any other collaboration. Included with the survey are recommendations intended to help DOE decide how best to support SMES research and development (R ampersand D). To summarize, I would say that important elements of a well-rounded SMES research program for DOE are as follows. (1) Construction of a large ETM. (2) Development of SMES as an enabling technology for solar and wind generation, especially in conjunction with the ETM program, if possible. (3) Development of small SMES units for electric networks, for rapid transit, and as noninterruptible power supplies [uses (2), (3), and (4) above]. In this connection, lightweight, fiber-reinforced polymer structures, which would be especially advantageous for space and transportation applications, should be developed. (4) Continued study of the potential impacts of high-temperature superconductors on SMES, with construction as soon as feasible of small SMES units using high-temperature superconductors (HTSs)

IEA countries energy policy. Report 1992

International Nuclear Information System (INIS)

1994-01-01

The International Energy Agency is interested by the energy policy of its 23 members countries. This book sums up the evolution of energy policy in 1991 and 1992, sticking particularly to energy proposal and demand, to energy efficiency, to interaction between energy and environment, to the energy technology and to research and development activities. The 23 countries are examined regularly. The elaborate examinations refer to the energy policy of each member country to dictate the common orientation of their policy. Ministers meetings of IEA take place regularly. The latest took place in PARIS on the fourth of June 1993 where the ministers confirmed that there were essential elements of the energy policy and that they recommended to all countries to take that in account in the formulation of their strategies. Beyond the examinations by country, this book contains a whole report which throws into relief the main new acts which were happened in the IEA members countries and a glimpse on the evolution of the energy situation in the no members countries. It gives specific data and informations on the governmental budgets allocated to research and development energy activities. 6 annexes, 12 graphs., 5 tabs

Yoshimoto, Takamitsu; Kinoshita, Koichiro; Kitamura, Hideki; Tanigawa, Ryoichi

The flame stability limits essentially define the fundamental operation of the combustion system. Recently the micro diffusion flame has been remarked. The critical conditions of the flame stability limit are highly dependent on nozzle diameter, species of fuel and so on. The micro diffusion flame of Methane/Propane and Hydrogen is formed by using the micro-scale nozzle of which inner diameter is less than 1mm. The configurations and behaviors of the flame are observed directly and visualized by the high speed video camera The criteria of stability limits are proposed for the micro diffusion flame. The objectives of the present study are to get further understanding of lifting/blow-off for the micro diffusion flame. The results obtained are as follows. (1) The behaviors of the flames are classified into some regions for each diffusion flame. (2) The micro diffusion flame of Methane/Propane cannot be sustained, when the nozzle diameter is less than 0.14 mm. (3) The diffusion flame cannot be sustained below the critical fuel flow rate. (4) The minimum flow which is formed does not depends on the average jet velocity, but on the fuel flow rate. (5) the micro flame is laminar. The flame length is decided by fuel flow rate.

1993-09-01

A series of gamma radiation surveys was conducted over Par Pond at the Savannah River Site (SRS) in August 1993, October 1991, and August 1992 as part of an effort to monitor the radiological changes around Par Pond as its water level was lowered. The results of an April 1989 survey, which was about one-half the area of those surveys listed above, were used as baseline data for the comparison. Gamma energy spectrum analysis revealed that the only man-made gamma ray emitter detected during the four surveys in the Par Pond area was cesium-137. The comparisons revealed that: (1) significant change in the radiological environment occurred along the Par Pond shoreline as the water levels were lowered, (2) the activity in Lower Three Runs Creek varied slightly as the level/flow rate changed during the pumping process, (3) minor changes occurred in areas adjacent to the Par Pond, and (4) little or no change occurred between surveys in the spatial distribution or kind of sources detected. All changes were directly related to the moisture variations (Par Pond water lowering, rainfall, waterway flow rates) between the survey periods. The distribution, kind, and activity of sources detected beyond the pond bed were consistent between surveys. 60 figs., 14 tabs

This publication, Electric Trade in the US 1992 (ELECTRA), is the fourth in a series of reports on wholesale power transactions prepared by the Electric Data Systems Branch, Survey Management Division, Office of Coal, Nuclear, Electric and Alternate Fuels, Energy Information Administration (EIA). The electric trade data are published biennially. The first report presented 1986 data, and this report provides information on the electric power industry during 1992. The electric trade data collected and presented in this report furnish important information on the wholesale structure found within the US electric power industry. The patterns of interutility trade in the report support analyses of wholesale power transactions and provide input for a broader understanding of bulk power market issues that define the emerging national electric energy policies. The report includes information on the quantity of power purchased, sold, exchanged, and wheeled; the geographical locations of transactions and ownership classes involved; and the revenues and costs. Information on the physical transmission system are being included for the first time in this publication. Transmission data covering investor-owned electric utilities were shifted from the Financial Statistics of Selected Investor-Owned Electric Utilities to the ELECTRA publication. Some of the prominent features of this year`s report include information and data not published before on transmission lines for publicly owned utilities and transmission lines added during 1992 by investor-owned electric utilities.

Krumbholz, E.; Kressing, F.

1992-09-01

The first edition of the 'World Uranium Hearing Grey Book' for the World Uranium Hearing in Salzburg, 13-19 September 1992 is meant to be a reference for people involved in the World Uranium Hearing. It is mostly made up to country by country surveys giving background information on the testimonies presented at the Hearing, and on many more cases. Included are two short articles: One on 'nukespeak' to make the reader aware of how the language of the nuclear industry influences our speaking and thinking; and an article on the wastes produced by uranium mines. Due to limited time and resources this documentation is not complete. Many questions remain. For example, information is rare about conditions in Eastern Europe. Also, some countries are given much more space than others, which does not indicate importance or seriousness of implications of uranium mining, weapons testing or nuclear waste storage in this particular country.

High-Flux Zeolitic Imidazolate Framework Membranes for Propylene/Propane Separation by Postsynthetic Linker Exchange.

Lee, Moon Joo; Kwon, Hyuk Taek; Jeong, Hae-Kwon

2018-01-02

While zeolitic imidazolate framework, ZIF-8, membranes show impressive propylene/propane separation, their throughput needs to be greatly improved for practical applications. A method is described that drastically reduces the effective thickness of ZIF-8 membranes, thereby substantially improving their propylene permeance (that is, flux). The new strategy is based on a controlled single-crystal to single-crystal linker exchange of 2-methylimidazole in ZIF-8 membrane grains with 2-imidazolecarboxaldehyde (ZIF-90 linker), thereby enlarging the effective aperture size of ZIF-8. The linker-exchanged ZIF-8 membranes showed a drastic increase in propylene permeance by about four times, with a negligible loss in propylene/propane separation factor when compared to as-prepared membranes. The linker-exchange effect depends on the membrane synthesis method. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Minimizing the entropy production in a chemical process for dehydrogenation of propane

International Nuclear Information System (INIS)

Rosjorde, A.; Kjelstrup, S.; Johannessen, E.; Hansen, R.

We minimize the total entropy production of a process designed for dehydrogenation of propane. The process consists of 21 units, including a plug-flow reactor, a partial condenser, two tray distillation columns and a handful of heat exchangers and compressors. The units were modeled in a manner that made them relatively insensitive to changes in the molar flow rates, to make the optimization more flexible. The operating conditions, as well as to some degree the design of selected units, which minimized the total entropy production of the process, were found. The most important variables were the amount of recycled propane and propylene, conversion and selectivity in the reactor, as well as the number of tubes in the reactor. The optimal conversion, selectivity and recycle flows were results of a very clear trade-off among the entropy produced in the reactor, the partial condenser and the two distillation columns. Although several simplifying assumptions were made for computational reasons, this shows for the first time that it is also meaningful to use the entropy production as an objective function in chemical engineering process optimization studies

Graphical abstract: - Highlights: • Comparative study of Al{sub 2}O{sub 3} phase on dehydrogenation of propane was implemented. • Pore structures and acid properties of Pt-Al{sub 2}O{sub 3} are correlated to the activities. • Pt-θ-Al{sub 2}O{sub 3} with abundant Cl content shows the highest activity and stability. - Abstract: The effects of two Al{sub 2}O{sub 3} phases, γ- and θ-Al{sub 2}O{sub 3}, and Cl component on the performances of Pt-Al{sub 2}O{sub 3} catalysts in the dehydrogenation of propane were investigated in this work. The catalysts were systematically characterized by various techniques, such as scanning transmission electron microscopy (STEM), temperature-programmed desorption with ammonia as probe molecules (NH{sub 3}-TPD) and temperature-programmed oxidation (TPO). The characterizations and catalytic results show that: (i) the pore structures and acid properties of the two Al{sub 2}O{sub 3} phases can change the quantity, location and property of the carbon deposition, (ii) the existence of Cl plays a significant role on the agglomeration of Pt particles and carbon deposition, which further influence the catalytic performances of Pt-Al{sub 2}O{sub 3} catalysts with different support phases for propane dehydrogenation.

Settles, R.

1992-10-01

A selection of ALEPH activities in 1991 is presented. ALEPH took ≅ 12pb -1 of good data around the Z 0 peak in that year to bring the total up to a half a million events. The silicon-strip vertex detector was commissioned successfully and performed to design specifications for all of the 1991 running. The examples of physics reviewed include an update on electroweak results, N ν counting with the single photon events, τ-branching ratio and -lifetime measurements, measurement of the B-hadron lifetime, evidence for the Λ b baryon, existence of the triple gluon vertex, the understanding of intermittency, and an update on the Higgs search. These analyses were done in 1991 and include the 1989-90 data. (orig.)
