    The 1953 discovery of the massive Pembina Cardium field near Drayton Valley, Alberta, was discussed. It was the largest field ever discovered in Canada, holding an estimated 7.8 billion barrels of crude. The Socony-Vacuum Exploration Company drilled the first well to 10,000 feet. The well produced light crude oil at a rate of 456 barrels per day. A second successful well was then drilled about 6 miles northeast of the discovery well. By the end of 1953, Socony and its partners had a total of 7 wells underway in the area, all testing the Cardium formation. By the end of 1954, the industry recognized the significance of the discovery, and 34 wells were being drilled in the area. Production from the field by the end of 1954 averaged 6,500 barrels per day from 85 wells. By 1955, the Pembina Cardium field, covering approximately 400,000 acres, was the largest in North America. Production from the field exceeded 76,600 barrels per year through 1955. It has been touted as the largest conventional oil accumulation, with a reserve of 7.8 billion barrels of oil in place, and the biggest discovery in the history of the Canadian oil industry. Other key events of 1953 included Saskatchewan's gas export policy; approval of a 22-year gas export permit for Westcoast Transmission Company; and completion of an oil pipeline from Edmonton to Vancouver. 1 tab., 1 fig.

    2018-02-01

    Full Text Available The paper deals with historical, economic and geographical features of sectoral and territorial consequences of the impact of military actions on the national economy in the Stalingrad region. The authors consider approaches to the management of the economy of the RSFSR in the prewar and postwar periods, their peculiarities and differences. The elements of monitoring the accounting of destruction caused by the military actions in sectoral and territorial aspects are identified. The use of archival sources, including the archives introduced into academic circulation for the first time, allows to investigate the reduction in the most important indicators of industrial production and agriculture of the region for the period of 1940–1943. In particular, the dynamics of production volumes at the industrial sites of the region, the number of people employed in the industry with specific companies during 1941–1943 were studied. The special attention is paid to such key parameters of agricultural production as acreage, the number of working and productive livestock. Territorial differences in the changes of agricultural production in administrative districts in 1940–1946 are identified. The effect of mobilization of men and equipment to the agricultural productivity is studied. Based on statistical reports, the extent of damage to educational institutions and health care is determined. The main indicators of socio-economic status of urban and rural population in comparison with the prewar period (taking into account monetary and natural income residents of the region are analyzed. Special attention is also paid to the study of the impact of military operations on the railway and vehicular transport infrastructure, which had played a key role in the Victory of the Soviet troops at Stalingrad and in the postwar reconstruction of the national economy.

    1970-01-01

    The Atomic Energy Act 1953-1966 establishes the Australian Atomic Energy Commission and lays down its powers, duties, rules of procedure and financing. The members of the Commission are appointed by the Governor-General. It is responsible, inter alia, for all activities covering uranium research, mining and trading as well as for atomic energy development and nuclear plant construction and operation. Its duties also include training of scientific research workers and collection and dissemination of information on atomic energy. For purposes of security, the Act further-more prescribes sanctions in relation to unauthorised acquisition or communication of information on this subject. Finally, the Act repeals the Atomic Energy (Control of Materials) Act 1946 and 1952. (NEA) [fr

  13. 8 December 1953 - 8 December 1963. Atomic co-operation in the United Nations

    International Nuclear Information System (INIS)

    1964-01-01

    Full text: Ten years ago, on 8 December 1953, President Eisenhower proposed to the General Assembly of the United Nations measures to build 'a new avenue to peace'. This was the beginning of the idea that international understanding can be fostered through peaceful atomic co-operation in an international organization. Re-reading the President's statement ten years later, one is impressed by the continued urgency of his message. What he said in fact was that the nations of the world were living in the shadow of an overwhelming atomic threat and that steps were necessary, even though modest and untried, to break the impasse between the East and the West in the very field which caused the most profound concern - atomic energy. The International Atomic Energy Agency became an institutional reality in 1957, when the first General Conference met with 56 members. It now has 83 members, and a further five nations will become members as soon as statutory formalities are completed. The activity on the part of the Agency during these six years has gradually expanded, although it has fallen short of earlier hopes in certain areas. Time and patience, however, have been required and 1963 foreshadows further progress. Ten years after the proposal of the idea, scientists and statesmen can look back and be gratified that a contribution has been made to international understanding. Scientists and statesmen can look ahead, hopefully, to a future of increasing activity in this special agency to develop co-operation and agreement in the field of atomic energy. (author)

    autumn and 51% in spring. A significant decline in pintail abundance starting in the late 1950s altered waterfowl composition on Klamath Basin refuges. As pintail declined, other species such as mallard (Anas platyrhynchos) and green-winged teal (Anas crecca) increased in abundance. Although Arctic nesting geese, including white-fronted (Anser albifrons), cackling Canada (Branta canadensis minima), white geese (lesser snow [Chen caerulescens caerulescens], and Ross’s [Chen rossii]) have become less prominent in recent decades, they reached an historically high abundance during autumn in the 1960s and 1970s, particularly on Tule Lake NWR.Tule Lake NWR supported the highest average autumn waterfowl populations until surpassed by Lower Klamath NWR around 1980. During the recent period (1977-2001), Lower Klamath NWR accounted for 60% of all waterfowl using the refuge complex in autumn and 61% in spring. Habitat diversity and wetland productivity contributed to its greater waterfowl abundance. Tule Lake NWR supported the most geese over the long term, 79% in autumn and 66% in spring; however, total waterfowl abundance on this refuge in autumn has been in decline, likely because of reduced diversity and productivity of sumps in the refuge. Upper Klamath, Klamath Marsh, and Clear Lake NWRs accounted for less than 8% of total waterfowl use in autumn and spring but provided diverse habitats for migrants.Waterfowl use-days on Klamath Basin refuges typically peaked in mid-autumn, decreased as migrants passed through the basin, and then reached a lesser peak during spring passage. Waterfowl abundance reached a pronounced peak in autumn during the early period (1953-76), but spring peak buildup was much less pronounced. For the recent period the autumn peak was more subdued.Waterfowl abundance, species composition, and distribution on Klamath Basin refuges have fluctuated over the decades and have been influenced by events such as productivity on breeding grounds and habitat

    2014-07-01

    Full Text Available In the ten years 1953-62, the average price level in Italy rose every year, with the exception of 1959. The present article examines the effects of this inflationary process on income distribution. To do so the author first determines the extent to which each productive sector contributed to the creation of the total surplus of money product over real product, and how such excess was distributed amongst the various income categories in each sector. Then, the losses in real purchasing power these categories suffered are examined. Finally, the net outcome between gains in money product and losses for each category is found. According to the author, the data suggests peculiarly Ricardian features: the increase in prices was largely due to a rise in rents and of sectoral incomes in which are hidden some forms of rent, in the twofold aspect of privileged positions and inefficiency.JEL: E24, E31, O15

  5. Agriculture, population, and economic planning in Ethiopia, 1953-1980.

    Science.gov (United States)

    Robinson, W C; Yamazaki, F

    1986-04-01

    This paper deals with the economic development of Ethiopia in the 3 decades between 1950 and 1980. In particular, it examines governmental efforts at agricultural planning during this period compared to the actual experience of the country. The dominant forces governing the changes that occurred in this period were accelerated population growth and the declining availability of arable land, which combined to push a fragile, traditional ecosystem to the brink of disaster. Government planning efforts had little impact in the pre-1974 period, since they were too modest and small scale to affect the highly traditional and primitive mode of peasant cultivation. The sweeping structural changes introduced by the new regime since 1974 seem to have mainly adverse effects and to have decreased both productivity and yields. Ethiopia lacks the basic infrastructure and incentive system to create an environment in which technological change is possible. Presumably the declining agricultural growth rate from 1953 to 1974 suggests that the traditional, prerevolution system was failing to create these favorable conditions and hence was losing the race with population growth. The post-1974 revolutionary government's policy has been, in effect, an effort to jump to an advanced phase of agricultural development, and this seems to have been even less successful. These plans have, in all fairness, been hamstrung since 1981 by drought, famine, and civil war, but have probably themselves contributed to the severity of those events. Overall, Ethiopian agricultural planning has not been notably successful. From 1953-1980, total agricultural production is estimated to have grown at a slowly decreasing rate. The collapse of agriculture due to several years of drought obviously cannot be blamed on government planning, but its severity clearly has been at least partly a function of policy failures.

    Between 1953 and 1970, studies on the long-term effects of external x-ray and γ irradiation on inbred and hybrid mouse stocks were carried out at the Biological and Medical Research Division, Argonne National Laboratory. The results of these studies, plus the mating, litter, and pre-experimental stock records, were routinely coded on IBM cards for statistical analysis and record maintenance. Also retained were the survival data from studies performed in the period 1943-1953 at the National Cancer Institute, National Institutes of Health, Bethesda, Maryland. The card-image data files have been corrected where necessary and refiled on hard disks for long-term storage and ease of accessibility. In this report, the individual studies and data files are described, and pertinent factors regarding caging, husbandry, radiation procedures, choice of animals, and other logistical details are summarized. Some of the findings are also presented. Descriptions of the different mouse stocks and hybrids are included in an appendix; more than three dozen stocks were involved in these studies. Two other appendices detail the data files in their original card-image format and the numerical codes used to describe the animal's exit from an experiment and, for some studies, any associated pathologic findings. Tabular summaries of sample sizes, dose levels, and other variables are also given to assist investigators in their selection of data for analysis.

    To review all notified cases of leprosy in England and Wales between 1953 and 2012. National surveillance study of all reported cases. England and Wales. Number and characteristics of reported cases. During this period, a total of 1449 leprosy cases were notified. The incidence fell from 356 new cases notified between 1953 and 1962 to 139 new cases between 2003 and 2012. Where data were available, leprosy was more common in men, 15-45 year olds and those from the Indian subcontinent. There was considerable undernotification in 2001-2012. The high level of under-reporting indicates a need for improved surveillance in the UK. Public Health England, in collaboration with the UK Panel of Leprosy opinion, has revised the UK Memorandum on Leprosy in order to provide updated guidance on diagnostic procedures, treatment, case management, contact tracing and notification.

    The etiology of leukemia is largely unknown. Ecological data indicating trends in incidence and survival can provide information about changes in risk factors, can reflect underlying changes in diagnostic classification, and can measure therapeutic advances. From the records of the Danish Cancer...... Registry with registration starting from 1943, we calculated age-specific, period-specific, and age-standardized (world standard) incidence rates of chronic lymphoid leukemia (CLL), acute lymphoid leukemia (ALL), chronic myeloid leukemia (CML), and acute myeloid leukemia (AML) for persons above the age...... of 18. Kaplan-Meier survival curves and median survival times were calculated. Between 1943 and 2003, there were 26,036 cases of leukemia reported. The age-specific incidence rates of CLL, CML, and AML were higher for older men and women, while the incidence rates of ALL by age were more homogeneous...

    Full Text Available This research examines on the reflection ofJeihan's thoughttraced via his paintingsproduced during 1953 until 2012. It uses historical method with hermeneutical approach. Jeihan’s childhood experienced abnormalities, that made him marginalized in his family and social environment. As the result, his personality became rough and rebellious. It affected his painting style that tend to be harsh and had no character. This bad temper attached him until 1953, when Jeihan studied painting in Himpunan Budaya Surakarta (HBS, and continued his higher education to Institut Teknologi Bandung (ITB. In order to understand painting style, it can be seen from line and color paintings that always progressed. It can be analyzed into four periods which colored by a different artistic style, that are seeking (1952-1965, discovery (1965-1975, maturation (1975-1985, and reaping period (1986-2012.

    Motohashi, Y

    1991-04-01

    The effects of socioeconomic factors on secular trends in suicide rates in Japan for the periods 1953-72 and 1973-86 were investigated using twelve socioeconomic indicators. Multiple regression analysis showed that the socioeconomic indicators affecting suicide rates were not identical in the two periods. The rates in both sexes in 1953-72 were closely related to unemployment rate and the labour force but between 1973 and 1986, divorce rate and the proportion in tertiary industry were most influential. The changes reflect the socioeconomic changes in industrial structure in Japan in transition from an industrial to a service economy.

  2. Portraits of a city: the photograph in the paper Paraná-Norte (1943-1953 and the magazine A Pioneira (1948-1954

    Full Text Available The city of Londrina (north of Paraná State emancipated politically on December 10, 1934, five years after the arrival of the pioneers of the Companhia de Terras Norte do Paraná (CTNP - mostly English owned company that began colonization in 1929. In October 1934, two months before being elevated to the status of municipality, was born the first communication vehicle in the city, the newspaper Paraná-Norte. Present from the beginning, the press reported on its pages the transformations that city suffered through the years, being a document of important historical value. This study therefore aims to analyze the beginning of the trajectory ofLondrina's press from the place occupied by the image in the pages of the city's first newspaper, Paraná-Norte (1934-1953 and the magazine A Pioneira (1948-1954. To understand the importance of photography published in such vehicles as trace for writing the history ofLondrina, it employed some research methodologies. The first was the literature, followed by the documentary analysis (MOREIRA, 2009 for all editions of the newspaper and magazine available to the public consultation, which allowed to write about the history of the two media pioneers. Already a comparative study of photography in Paraná-Norte and A Pioneira was done by iconographic analysis, proposed by Kossoy (2001. Faced with the impossibility of studying the universe of photographs published by two journals, we chose to select, via random draw, one copy per year of circulation newspaper and magazine. Thus, the study focused on 18 editions of Paraná-Norte (for the years 1951 and 1952 there are no copies available and 7 of the magazine A Pioneira. Drawing on theoretical frameworks that deal with interfaces between story and image, press photography and memory, portraits and family albums, we conclude that, although the use of imagery has been explored differently by the two vehicles, even because of difficulties technical and financial, in

    Full Text Available The aim of this work is to describe German and Republican Fascists secret services espionage and sabotage networks, their missions and their agents who were sent to the South-Central Italy, between 1943 and 1945, with the goal of obstructing the Allied advance. The two German secret services, namely Abwehr and Sicherheitsdienst, recruited Italian agents (who belonged to the Milizia, the Black Brigades or Borghese’s Decima Mas to take part in espionage and sabotage operations beyond the Allied lines. Even the fascists themselves, through the newborn SID or other groups like Prince Pignatelli’s or Pucci-Del Massa Office, tried to plan espionage networks but also to prepare the ground for the survival of the fascism after the end of the war.

  5. Partisan movement in southern Ukraine in 1943–1944

    2017-08-01

    Full Text Available The events of the Revolution of Dignity and war in Donbass formed the experience of the armed and sociopolitical confrontation of the Second World War period, especially in the steppe and industrial south of Ukraine. Partisan struggle in this region had its own specifics, which requires its comprehension and generalization. The article is devoted to the final stage (1943–1944 of the development of the Soviet partisan movement in Southern Ukraine. This region is characterized by the absence of large forest areas and the presence of large industrial centers. Considering this, underground forms of struggle became the priority ones. Nevertheless, partisan methods of resistance to the invaders were also used actively. Based on the analysis of a wide range of archival documents of the central and regional archives, it has been established that the final stage of development of the partisan movement in its characteristics differed significantly from the initial stage (1941–1942. Its features were: the excellent emergence of partisan formations and a modified tactic of fighting against the invaders. In particular this happened in years 1943–1944. Partisan detachments were formed as a result of the organizational activities of the landing groups, abandoned from «Big Land» or underground. It has been found out during the investigation that they were active in the approaching front line: they attacked the occupation troops and institutions, carried out diversionary acts, conducted reconnaissance in the interests of the Red Army. An outstanding page of the Resistance movement in the south of Ukraine was Pavlograd uprising of 1943. In addition, the quality of the source base has been described in the article. It has been established that the documents of the Soviet archives contain a considerable part of falsifications and exaggerations. Therefore, researchers are being recommended to use the quantitative indicators of Soviet documents very

    Full Text Available The study of the renovation of literary criticism in 1950s Argentina has tended to focus on a few emblematic publications, such as Contorno (1953-9, which represented but the tip of an iceberg of proliferating criticism during that period. In a time when the rapid massification of book production and circulation required the redefinition of the status and the legitimacy of literary practices, the analysis of Bibliograma (1953-7 offers key insights into the hopes and fears that turned criticism into a ground for activism.

    1982-01-01

    Since its beginning in 1943, ORNL has generated large amounts of solid, liquid, and gaseous radioactive waste material as a by-product of the basic research and development work carried out at the laboratory. The waste system at ORNL has been continually modified and updated to keep pace with the changing release requirements for radioactive wastes. Major upgrading projects are currently in progress. The operating record of ORNL waste operation has been excellent over many years. Recent surveillance of radioactivity in the Oak Ridge environs indicates that atmospheric concentrations of radioactivity were not significantly different from other areas in East Tennesseee. Concentrations of radioactivity in the Clinch River and in fish collected from the river were less than 4% of the permissible concentration and intake guides for individuals in the offsite environment. While some radioactivity was released to the environment from plant operations, the concentrations in all of the media sampled were well below established standards

  9. Possible windborne spread of myxomatosis to England in 1953.

    Sellers, R F

    1987-02-01

    An analysis of the meterological conditions showed that the first outbreaks of myxomatosis in S.E. England in 1953 could have resulted from wind carriage of insects infected with myxoma virus from northern France. South-easterly winds on the night 11-12 August would have carried the insects 120-160 km from the Départements of Nord, Pas de Calais and Somme across the English Channel to near Edenbridge, Kent. The flight would have taken 6.5-8.5 h at wind speeds of 15-22 km h-1. On the night 11-12 August, temperatures increased with height (inversion) up to 500 m; at ground level temperature was around 19 degrees C and at 500 m was 25 degrees C. Insects would have travelled up to the top of the inversion arriving on 12 August as the inversion declined. Two or possibly three generations of infection would have taken place before the disease was seen around the middle of September 1953. The most likely insect was the mosquito Anopheles atroparvus which breeds along the coastal marshes of England and northern France and which has been shown experimentally and in the field to transmit myxoma virus mechanically.

    The results of photometric and time-resolved optical observations of the fields of the recently discovered ultra-fast radio pulsars, PSR 1937+214 and PSR 1953+29 (Backer et al. 1982; Boriakoff et al. 1983) are reported. Deep images of the fields reveal no conspicuous optical counterpart for PSR 1937+214, though a star with m/sub r/ approx. 20.5 is coincident with the position of PSR 1953+29. Time-resolved images of the fields of both objects, obtained with a new stroboscopic technique, have yielded upper limits on the pulsed near-infrared emission from each object. Constraints on the physical models for these systems derived from the optical studies are briefly discussed. 25 references, 9 figures, 4 tables

    HESS J1943+213, a TeV point source close to the Galactic plane recently discovered by the H.E.S.S. Collaboration, was proposed to be an extreme BL Lacertae object, though a pulsar wind nebula (PWN) nature could not be completely discarded. To investigate its nature, we performed high-resolution radio observations with the European Very Long Baseline Interferometry Network (EVN) and reanalyzed archival continuum and H I data. The EVN observations revealed a compact radio counterpart of the TeV source.

The radio/X-ray source appears immersed in a {approx}1' elliptical feature, suggesting a possible galactic origin (PWN nature) for the HESS source.

  8. China, Japan, and the United States in World War II: The Relinquishment of Unequal Treaties in 1943

    2015-08-01

    Full Text Available This paper aims to examine how the United States transformed its foreign policy to promote China as an “equal state” in international politics during World War II, with focus on the process of the American relinquishment of its unequal treaties with China in 1943. In particular, it concentrates on analyzing the conflicts between the United States and Japan in the process of relinquishment. By examining the rivalry between the United States and Japan in the social warfare – propaganda – we can see that the relinquishment of the unequal treaties in 1943 not only marked a historical turning point in America’s China policy, but also had a great impact on the transformation of East Asian politics in World War II and its influence in the world politics.

  9. The extreme carbon dioxide outburst at the Menzengraben potash mine 7 July 1953

    Hedlund, Frank Huess

    2012-01-01

    Carbon dioxide is an asphyxiant and an irritant gas. An extreme outburst of carbon dioxide took place 7 July 1953 in a potash mine in the former East Germany. During 25 min, a large amount of CO2 was blown out of the mine shaft with great force. It was wind still and concentrated CO2 accumulated....... It is concluded that 1100–3900 tonnes of CO2 were blown out of the mine shaft, possibly with intensities around 4 tonnes/s. It is also concluded that the large majority of the gas escaped as a near-vertical high-velocity jet with only little loss of momentum due to impingement. The release was modelled using...... histories to date include sudden releases of CO2 of up to 50 tonnes only, far too small to provide a suitable empirical perspective on predicted hazard distances for CCS projects. The 1953 outburst contributes to filling this gap....

    This paper reviews Churchill's illnesses in February 1943 and August/September 1944 when he developed pneumonia; on the first occasion this followed a cold and sore throat. Churchill was managed at home by Sir Charles Wilson (later Lord Moran) with the assistance of two nurses and the expert advice of Dr Geoffrey Marshall, Brigadier Lionel Whitby and Colonel Robert Drew. A sulphonamide (sulphathiazole on the first occasion) was prescribed for both illnesses. Churchill recovered, and despite his illnesses continued to direct the affairs of State from his bed. On the second occasion, Churchill's illness was not made public.

    We examine operating room productivity on the example of hospitals in Germany with independent anesthesiology departments. Linked to anesthesiology group literature, we use the ln(Total Surgical Time/Total Anesthesiologists Salary) as a proxy for operating room productivity. We test the association between operating room productivity and different structural, organizational and management characteristics based on survey data from 87 hospitals. Our empirical analysis links improved operating room productivity to greater operating room capacity, appropriate scheduling behavior and management methods to realign interests. From this analysis, the enforcing jurisdiction and avoiding advance over-scheduling appear to be the implementable tools for improving operating room productivity.

    The forced method of exploitation was initiated at Oktyabrskii field in 1943. In this method, the wells are equipped with submerged electric pumps.From 1943 to 1967, this method of pumping wells with highly water-cut production, recovered an additional 1,876 tons of oil. Better results were obtained when the forced exploitation method was combined with waterflooding. The high profitability of using submerged centrifugal pumps in oil wells with high water production is shown. Year-by-year results obtained with this production method are shown in 4 tables.

    Past epidemiological studies of workers in a nickel refinery in Clydach, Wales, have shown evidence of large excess respiratory cancer mortality risks [lung cancer relative risk (RR) ≈ 3; nasal cancer RR ≈ 140] in those employed prior to 1930, with risks dropping dramatically in workers hired subsequently. The pre-1930 risks have generally been attributed to high exposures to mixtures of nickel compounds. More recent studies of this refinery's workers have focused on those first hired in 1953, when many of the operations that presumably gave rise to the high exposures were no longer in operation. While these studies have shown greatly decreased lung cancer risks overall (RR ≈ 1.4), and no substantive evidence of increased nasal cancer risk, the absence of reliable exposure estimates have made it difficult to ascertain whether the increased lung cancer risks are nickel related or due to other factors. This study uses nickel measurements from the 1970s to the present, documentation of process changes, and dust measurements taken around the 1950s to construct an exposure matrix for the recent cohort. It provides evidence of at least 30-fold decreases in levels of nickel exposure from the 1950s to the present, with estimated inhalable nickel concentrations in the 1950s in excess of 5mg Ni m(-3). © The Author 2014.

    This monograph presents a broad treatment of developments in an area of constructive approximation involving the so-called "max-product" type operators. The exposition highlights the max-product operators as those which allow one to obtain, in many cases, more valuable estimates than those obtained by classical approaches. The text considers a wide variety of operators which are studied for a number of interesting problems such as quantitative estimates, convergence, saturation results, localization, to name several. Additionally, the book discusses the perfect analogies between the probabilistic approaches of the classical Bernstein type operators and of the classical convolution operators (non-periodic and periodic cases), and the possibilistic approaches of the max-product variants of these operators. These approaches allow for two natural interpretations of the max-product Bernstein type operators and convolution type operators: firstly, as possibilistic expectations of some fuzzy variables, and secondly,...

In the second, I try to analyze the conceptions about State and Nation between 1945 and 1955. In the third, I will analyze some elements of the "de-peronizador" project of the dictatorship installed in 1955 and the various institutional mechanisms implemented by the State in order to bury definitively the Peronist identity. Finally, by crosslinking various theoretical contributions, I will try to come to some conclusions aimed to highlight the historical emergence of a form of State racism in the country.

    Full Text Available Background: First Nations people are experiencing increasing rates of obesity and type 2 diabetes but no anthropometric information exists from before the 1950s to provide context to these epidemics. Objective: To compare anthropometric indices of First Nations children and youth on first entering residential schools with historical and contemporary reference groups. Methods: This observational cross-sectional study used archival records from the Department of Indian Affairs to calculate body mass index (BMI, height for age (HA and weight for age (WA of all known children and youth undergoing physical examinations on first entering residential schools in Saskatchewan and Manitoba from 1919 to 1953. Proportions of children and youth in each BMI category were determined by age, sex, time period and residential school. Z-scores for HA and WA were determined by age group and sex. Finally, median heights and weights were compared with a non-Indigenous cohort from the 1953 Canadian survey. Results: On admission to residential schools, 1,767 First Nations children and youth (847 boys, 920 girls were more likely to have normal BMIs (79.8% than Canadian children and youth today (66.5%, but lower rates of overweight/obesity (10.9% vs. 32.0% and higher rates of underweight (9.3% vs. −2, age-specific median heights tended to be higher than Canadian children and youth in 1953. Under 3% of children and youth had WA Z-scores of >−2. Conclusions: A large majority of First Nations children and youth exhibited normal anthropometric indices on first entering residential schools in Manitoba and Saskatchewan from 1919 to 1953. These historical findings provide an important context to the current epidemics of obesity and type 2 diabetes and suggest that the nutritional conditions in these First Nations children's communities were satisfactory during the residential school era.

    Reconstructing the transmission history of infectious diseases in the absence of medical or epidemiological records often relies on the evolutionary analysis of pathogen genetic sequences. The precision of evolutionary estimates of epidemic history can be increased by the inclusion of sequences derived from ‘archived’ samples that are genetically distinct from contemporary strains. Historical sequences are especially valuable for viral pathogens that circulated for many years before being formally identified, including HIV and the hepatitis C virus (HCV). However, surprisingly few HCV isolates sampled before discovery of the virus in 1989 are currently available. Here, we report and analyse two HCV subgenomic sequences obtained from infected individuals in 1953, which represent the oldest genetic evidence of HCV infection. The pairwise genetic diversity between the two sequences indicates a substantial period of HCV transmission prior to the 1950s, and their inclusion in evolutionary analyses provides new estimates of the common ancestor of HCV in the USA. To explore and validate the evolutionary information provided by these sequences, we used a new phylogenetic molecular clock method to estimate the date of sampling of the archived strains, plus the dates of four more contemporary reference genomes. Despite the short fragments available, we conclude that the archived sequences are consistent with a proposed sampling date of 1953, although statistical uncertainty is large. Our cross-validation analyses suggest that the bias and low statistical power observed here likely arise from a combination of high evolutionary rate heterogeneity and an unstructured, star-like phylogeny. We expect that attempts to date other historical viruses under similar circumstances will meet similar problems. PMID:23938759

  18. Mortality and causes of death among workers exposed to phosgene in 1943-45

    Polednak, A.P.; Hollis, D.R.

    1985-01-01

    Mortality and causes of death from death certificates were analyzed among workers exposed to phosgene while working at a uranium-processing plant in Tennessee in 1943-45. Standardized mortality ratios (SMRs) were calculated by using death rates for U.S. white males. As of 1979, SMRs for all causes and for various selected causes were similar in 694 male chemical workers chronically exposed to low levels of phosgene in 1943-45 and in 9280 male controls who worked at the same plant. SMRs for diseases of the respiratory system were 107 (14 observed vs. 13.07 expected) in the chemical workers and 119 (292 observed vs. 245.75 expected) in the controls. In a group of 106 males who were acutely exposed to high levels of phosgene, there were 41 deaths observed vs. 33.87 expected (SMR = 121; 95% confidence limits = 86 and 165). One death, occurring within 24 hours of exposure, was from pulmonary edema due to phosgene poisoning (coded to accidental causes). Five deaths were coded to diseases of the respiratory system (SMR = 266; 95% CL = 86 and 622); in 2 of these 5 deaths, bronchitis due to phosgene exposure had been reported in 1945. Among 91 female workers with acute high-level phosgene exposure, frequencies of symptoms and early health effects (pneumonitis and bronchitis) differed from those reported for the 106 male cases; preliminary data on vital status of these females are too incomplete for analysis, and further follow-up is needed

    Full Text Available The years of 1953–1960 entered in national history of book graphics as a stage marked by increases in professionalism. Considerable revival of all processes of art becomes more pronounced towards 1957 and 1960, marked by several important events (First All-Union Congress of Union of Artists Formation, Union Jubilee Exhibition dedicated to 40 years anniversary of the Great October, the participation of young artists from the Soviet Union in the VIth World Festival of Youth and Students in Moscow, the Decade of Moldovan Literature and Art in Moscow etc.. More pronounced will became the trend of Moldovan national school to specify the ethnic character. At that time, spiritual processes coincided with the broadening of spheres of knowledge. Given promoting of innovation in the editorial process, the elements of narrative and documentary, were enriched with new forms of conventional treatment of fine art images. The remarkable masters of the book graphics at this time where Leonid Grigoraşenco, Ilia Bogdesco, Boris Nesvedov. After 1953, the Moldovan Soviet art of book graphics, was additioned by already established masters, which have started working young as Igor Vieru, Boris Nesvedov, Iacob Averbuh, Ghennadi Zikov, Vasili Ţehmister, Filimon Hămuraru, Nikolai Makarenko etc.

  1. How do strategic decisions and operative practices affect operating room productivity?

    2011-12-01

    Surgical operating rooms are cost-intensive parts of health service production. Managing operating units efficiently is essential when hospitals and healthcare systems aim to maximize health outcomes with limited resources. Previous research about operating room management has focused on studying the effect of management practices and decisions on efficiency by utilizing mainly modeling approach or before-after analysis in single hospital case. The purpose of this research is to analyze the synergic effect of strategic decisions and operative management practices on operating room productivity and to use a multiple case study method enabling statistical hypothesis testing with empirical data. 11 hypotheses that propose connections between the use of strategic and operative practices and productivity were tested in a multi-hospital study that included 26 units. The results indicate that operative practices, such as personnel management, case scheduling and performance measurement, affect productivity more remarkably than do strategic decisions that relate to, e.g., units' size, scope or academic status. Units with different strategic positions should apply different operative practices: Focused hospital units benefit most from sophisticated case scheduling and parallel processing whereas central and ambulatory units should apply flexible working hours, incentives and multi-skilled personnel. Operating units should be more active in applying management practices which are adequate for their strategic orientation.

    1955-01-01

    During the summer of 1953 the areas investigated for radioactive deposits in Alaska were on Nikolai Creek near Tyonek and on Likes Creek near Seward in south-central Alaska where carnotite-type minerals had been reported; in the headwaters of the Peace River in the eastern part of the Seward Peninsula and at Gold Bench on the South Fork of the Koyukuk River in east-central Alaska, where uranothorianite occurs in places associated with base metal sulfides and hematite; in the vicinity of Port Malmesbury in southeastern Alaska to check a reported occurrence of pitchblende; and, in the Miller House-Circle Hot Springs area of east-central Alaska where geochemical studies were made. No significant lode deposits of radioactive materials were found. However, the placer uranothorianite in the headwaters of the Peace River yet remains as an important lead to bedrock radioactive source materials in Alaska. Tundra cover prevents satisfactory radiometric reconnaissance of the area, and methods of geochemical prospecting such as soil and vegetation sampling may ultimately prove more fruitful in the search for the uranothorianite-sulfide lode source than geophysical methods.

    Losinger, W C; Heinrichs, A J

    1996-03-01

    A national US survey collected data on herd milk production and management of Holstein herds. Step-wise selection identified management practices that were related to herd milk production using only operations that calculated herd milk production as well as using data from all operations. Results were similar. Milk production was highest in the West. Operations with 25% registered cattle had higher production than operations with no registered cattle. Dairy operations that reported a mean BW > 545 kg at first calving had higher mean milk production than operations with a mean BW or = 27 mo at first calving. In addition, use of the following management practices was associated with higher rolling herd average milk production: calves born in individual areas in buildings, calves hand-fed first colostrum, starter grain fed to preweaned calves, ionophores fed to heifers from birth to first calving, DHIA record-keeping system used, computerized records, and no new cattle introduced in the previous 12 mo.

  13. Precursory earthquakes of the 1943 eruption of Paricutin volcano, Michoacan, Mexico

    Yokoyama, I.; de la Cruz-Reyna, S.

    1990-12-01

    Paricutin volcano is a monogenetic volcano whose birth and growth were observed by modern volcanological techniques. At the time of its birth in 1943, the seismic activity in central Mexico was mainly recorded by the Wiechert seismographs at the Tacubaya seismic station in Mexico City about 320 km east of the volcano area. In this paper we aim to find any characteristics of precursory earthquakes of the monogenetic eruption. Though there are limits in the available information, such as imprecise location of hypocenters and lack of earthquake data with magnitudes under 3.0. The available data show that the first precursory earthquake occurred on January 7, 1943, with a magnitude of 4.4. Subsequently, 21 earthquakes ranging from 3.2 to 4.5 in magnitude occurred before the outbreak of the eruption on February 20. The (S - P) durations of the precursory earthquakes do not show any systematic changes within the observational errors. The hypocenters were rather shallow and did not migrate. The precursory earthquakes had a characteristic tectonic signature, which was retained through the whole period of activity. However, the spectra of the P-waves of the Paricutin earthquakes show minor differences from those of tectonic earthquakes. This fact helped in the identification of Paricutin earthquakes. Except for the first shock, the maximum earthquake magnitudes show an increasing tendency with time towards the outbreak. The total seismic energy released by the precursory earthquakes amounted to 2 × 10 19 ergs. Considering that statistically there is a threshold of cumulative seismic energy release (10 17-18ergs) by precursory earthquakes in polygenetic volcanoes erupting after long quiescence, the above cumulative energy is exceptionally large. This suggests that a monogenetic volcano may need much more energy to clear the way of magma passage to the earth surface than a polygenetic one. The magma ascent before the outbreak of Paricutin volcano is interpretable by a model

    Based on the forest resources investigation data and the forest fire inventory in 1953-2011, in combining with our field research in burned areas and our laboratory experiments, this paper estimated the carbonaceous gases carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and nonmethane hydrocarbons (NMHC) emission from the forest fires in Xiao Xing' an Mountains of Heilongjiang Province, Northeast China in 1953-2011. The total carbon emission from the forest fires in the Xiao Xing'an Mountains in 1953-2011 was 1.12 x 10(7) t, and the annual emission was averagely 1.90 x10(5) t, accounting for 1.7% of the annual average total carbon emission from the forest fires in China. The emission of CO2, CO, CH4, and NMHC was 3.39 x 10(7), 1.94 x 10(5), 1.09 x 10(5), and 7.46 x 10(4) t, respectively, and the corresponding annual average emission was 5.74 x 10(5), 3.29 x 10(4), 1.85 x 10(3), and 1.27 x 10(3) t, accounting for 1.4%, 1.2%, 1.7%, and 1.1% of the annual carbonaceous gases emitted from the forest fires in China, respectively. The combustion efficiency and the carbon emission per unit burned area of different forest types decreased in order of coniferous forest > broad-leaved forest > coniferous broadleaved mixed forest. Some rational forest fire management measures were put forward.

    2017-12-01

    Full Text Available Epistemological considerations of philosophers and scientists from the late nineteenth century to the mid-twentieth century guided Brazilian physiologist Miguel Ozório de Almeida (1890-1953 in formulating his researches and participating in national and international scientific debates. With his siblings, Álvaro Ozório de Almeida and Branca de Almeida Fialho, he participated in debates on Brazilian educational and scientific system’s reform and in international organizations. The family’s residence in Rio de Janeiro housed a laboratory that became a reference in experimental physiology researches in Brazil. This article aims to present Miguel Ozório de Almeida’s conception of science, constructed mainly within the private laboratory’s sociability, providing new aspects of scientific work production in Brazil in the early twentieth century. I argue that Ozório de Almeida’s stand as an internationalist physiologist in national and international contexts was related to his reading of texts by Ernest Mach, Pierre Duhem, Henri Poincaré and William James.

    1996-07-01

    This document assesses the impact of radioactive activation products released from SRS facilities since the first reactor became operational late in 1953. The isotopes reported here are those whose release resulted in the highest dose to people living near SRS: 32 P, 51 Cr, 60 C, and 65 Zn. Release pathways, emission control features, and annual releases to the aqueous and atmospheric environments are discussed. No single incident has resulted in a major acute release of activation products to the environment. The releases were the result of normal operations of the reactors and separations facilities. Releases declined over the years as better controls were established and production was reduced. The overall radiological impact of SRS activation product atmospheric releases from 1954 through 1994 on the offsite maximally exposed individual can be characterized by a total dose of 0.76 mrem. During the same period, such an individual received a total dose of 14,400 mrem from non-SRS sources of ionizing radiation present in the environment. SRS activation product aqueous releases between 1954 and 1994 resulted in a total dose of 54 mrem to the offsite maximally exposed individual. The impact of SRS activation product releases on offsite populations also has been evaluated

    To identify spinal injuries in Canadian ice hockey from 2006 to 2011 and to discuss data from 1943 to 2011 and impact of injury prevention programs. Data about spinal injuries with and without spinal cord injury in ice hockey have been collected by ThinkFirst's (now Parachute Canada) Canadian Ice Hockey Spinal Injuries Registry since 1981 through questionnaires from practitioners, ice hockey organizations, and media. All Canadian provinces and territories. All registered Canadian ice hockey players. Age, gender, level of play, location, mechanism of injury. Incidence, incidence rate, prevalence, and nature (morbidity) of the injuries. Between 2006 and 2011, 44 cases occurred, 4 (9.1%) of which were severe. The incidence in the recent years continues to be lower than the peak years. From 1943 to 2011, 355 cases have been documented, primarily males (97.7%) and cervical spine injuries (78.9%), resulting from impact with the boards (64.2%). Check or push from behind (36.0%) was still the most common cause of injury, although slightly lower during 2006 to 2011. From 1943 to 2011, Prince Edward Island, New Brunswick, and British Columbia/Yukon had the highest injury rates. Ontario and Quebec continued to show markedly different injury rates, with Ontario more than twice that of Quebec. Current data for 2006 to 2011 indicate that spinal injuries in ice hockey continue to occur, although still at lower rates than the peak years 1982 to 1995. It is imperative to continue educating players and team officials about spinal injury prevention and to reinforce the rules against checking or pushing from behind to reduce the incidence of these serious injuries.

    Full Text Available Individuals who use hair smoothing products at home or in a salon work environment are at risk of exposure to various chemical compounds. Formaldehyde mixed with keratin as a hair straightening product is in common use by women in Saudi Arabia. The high temperatures used during blow-drying can release gas fumes that have several implications to include irritation of the skin, eyes and respiratory complications. Furthermore, formaldehyde is classified as a known human carcinogen. The aim of this study is to assess the source of keratin hair treatment among women, demonstrate the symptoms related to formaldehyde exposure during keratin hair treatment process and determine the practices that can increase the exposure to formaldehyde and to evaluate the level of formaldehyde in the keratin hair treatment products. A national cross-sectional survey was first conducted during March-April 2017 on Saudi Arabian children and women aged between the age of 12 and 50 years old. A standardized, fully confidential questionnaire was provided to participating members. A total of 330 filled questionnaires were obtained within the study location. Moreover, 30 hair salons that used keratin-based products were visited in 3 different cities in Al Qassim province to check the location of keratin hair treatment, ventilation procedures and take samples of hair products that were later analyzed. Most commonly reported symptom was irritation of the eyes reported by 135 people. Other symptoms described include irritation of throat, burning sensation of the nose, headache and nausea. Argan e Ojon was one of the most famous product tested in this study with formaldehyde levels above 0.2% threshold (0.35%. It is worrying thatArgan e Ojon does not comply with GSO 1943 and SASO 1953 standards. A majority of salons demonstrated poor ventilation measures and failed to isolate their clients from the general public and salon workers. With the evident complications, more should be

  5. From playfulness and self-centredness via grand expectations to normalisation: a psychoanalytical rereading of the history of molecular genetics.

    Zwart, H A E

    2013-11-01

    In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943-1953); (2) the latency period, with a focus on the development of basic skills (1953-1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989-2003) and (4) adulthood (2003-present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy--have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as 'relevance', 'responsible innovation' and 'promise management'.

    2016-07-01

    Current descriptions of the ab initio density matrix renormalization group (DMRG) algorithm use two superficially different languages: an older language of the renormalization group and renormalized operators, and a more recent language of matrix product states and matrix product operators. The same algorithm can appear dramatically different when written in the two different vocabularies. In this work, we carefully describe the translation between the two languages in several contexts. First, we describe how to efficiently implement the ab initio DMRG sweep using a matrix product operator based code, and the equivalence to the original renormalized operator implementation. Next we describe how to implement the general matrix product operator/matrix product state algebra within a pure renormalized operator-based DMRG code. Finally, we discuss two improvements of the ab initio DMRG sweep algorithm motivated by matrix product operator language: Hamiltonian compression, and a sum over operators representation that allows for perfect computational parallelism. The connections and correspondences described here serve to link the future developments with the past and are important in the efficient implementation of continuing advances in ab initio DMRG and related algorithms.

    Poliomyelitis has historically been endemic in China and has been considered an important cause of disability and death. We reviewed strategies and measures of poliomyelitis control and eradication from 1953 to 2012. Data from notifiable disease and routine immunization reporting systems and acute flaccid paralysis (AFP) surveillance were analyzed. About 20 000 poliomyelitis cases were reported annually in the prevaccine era. During 1965-1977, live, attenuated oral poliomyelitis vaccine (OPV) was administered to children through annual mass campaigns in the winter, and the number of poliomyelitis cases started to decline. A cold chain system was established during 1982, and OPV coverage increased during the early stage of the Expanded Programme on Immunization, from 1978 to 1988. Between 1989 and 1999, routine immunization was strengthened, supplementary immunization activities (SIAs) were conducted, and the AFP surveillance system was established. China reported a last indigenous poliomyelitis case in 1994 and was certified as free of polio in 2000. To maintain its polio-free status, China kept >90% coverage of 3 doses of OPV, conducted SIAs in high-risk areas, and maintained high-quality of AFP surveillance. China succeeded in stopping the outbreak in Xinjiang in 2011. China's polio-free status was achieved and maintained through strengthening routine immunization and implementing SIAs and AFP surveillance. © The Author 2014.

  11. A consideration of the operation of automatic production machines.

    2015-01-01

    At worksites, various automatic production machines are in use to release workers from muscular labor or labor in the detrimental environment. On the other hand, a large number of industrial accidents have been caused by automatic production machines. In view of this, this paper considers the operation of automatic production machines from the viewpoint of accident prevention, and points out two types of machine operation - operation for which quick performance is required (operation that is not permitted to be delayed) - and operation for which composed performance is required (operation that is not permitted to be performed in haste). These operations are distinguished by operation buttons of suitable colors and shapes. This paper shows that these characteristics are evaluated as "asymmetric on the time-axis". Here, in order for workers to accept the risk of automatic production machines, it is preconditioned in general that harm should be sufficiently small or avoidance of harm is easy. In this connection, this paper shows the possibility of facilitating the acceptance of the risk of automatic production machines by enhancing the asymmetric on the time-axis.

    Statistics of injuries arising in amateur boxing in the Royal Air Force in the 14 years 1953-66 are given. There were 240 injuries including two deaths in the 14 years. During the seven years 1960-66, four men out of every thousand entering the ring received injuries to the head or neck which kept them off work for 48 hours or more. No case of the punch-drunk syndrome was seen. PMID:5723355

  14. A non-perturbative operator product expansion

    Nucleon structure functions can be observed in Deep Inelastic Scattering experiments, but it is an outstanding challenge to confront them with fully non-perturbative QCD results. For this purpose we investigate the product of electromagnetic currents (with large photonmomenta) between quark states (of low momenta). By means of an Operator Product Expansion the structure function can be decomposed into matrix elements of local operators, and Wilson coefficients. For consistency both have to be computed non-perturbatively. Here we present precision results for a set of Wilson coefficients. They are evaluated from propagators for numerous quark momenta on the lattice, where the use of chiral fermions suppresses undesired operator mixing. This overdetermines the Wilson coefficients, but reliable results can be extracted by means of a Singular Value Decomposition. (orig.)

  15. Semicrossed products of operator algebras by semigroups

    2017-01-01

    The authors examine the semicrossed products of a semigroup action by *-endomorphisms on a C*-algebra, or more generally of an action on an arbitrary operator algebra by completely contractive endomorphisms. The choice of allowable representations affects the corresponding universal algebra. The authors seek quite general conditions which will allow them to show that the C*-envelope of the semicrossed product is (a full corner of) a crossed product of an auxiliary C*-algebra by a group action. Their analysis concerns a case-by-case dilation theory on covariant pairs. In the process we determine the C*-envelope for various semicrossed products of (possibly nonselfadjoint) operator algebras by spanning cones and lattice-ordered abelian semigroups.

  16. On τ-Compactness of Products of τ-Measurable Operators

    2017-12-01

    Let M be a von Neumann algebra of operators on a Hilbert space H, τ be a faithful normal semifinite trace on M. We obtain some new inequalities for rearrangements of τ-measurable operators products. We also establish some sufficient τ-compactness conditions for products of selfadjoint τ-measurable operators. Next we obtain a τ-compactness criterion for product of a nonnegative τ-measurable operator with an arbitrary τ-measurable operator. We construct an example that shows importance of nonnegativity for one of the factors. The similar results are obtained also for elementary operators from M. We apply our results to symmetric spaces on (M, τ ). The results are new even for the *-algebra B(H) of all linear bounded operators on H endowed with the canonical trace τ = tr.

    This essay is on the writings of sanitary doctor Geraldo Horácio de Paula Souza in Eugenia e Imigração (1928) and, after an official trip to the Orient, in Digressões sobre a medicina chinesa clássica (1942) and A sabedoria chinesa diante da ciência ocidental e a Escola Médica de Pequim (1943). The documents, analyzed according to the conceptual approach of Carlo Ginzburg, indicate a change in his view of the Chinese. Trained according to the Rockefeller Foundation's model of experimental medicine, Geraldo de Paula Souza was guided in his work by scientific rigor and record imagery. In his youth he was of the opinion that the Chinese civilization was stagnated, but this view changed after his visit, when he perceived the Chinese republic's capacity to modernize.

    Colombian physician Luis Benigno Patiño Camargo was one of the pioneers in the study of rickettsioses in South America, demonstrating for the first time in Colombia the presence of Rickettsia rickettsii as the etiological agent of a highly deadly exanthematic febrile syndrome in the 1930s. However, Patiño-Camargo performed other investigations from 1917-1943, which represent the first descriptions and scientific evidence of the presence of R. prowazekii and R. typhi in Colombia. Almost 60 years after the latest research conducted by Dr. Patiño-Camargo, rickettsioses were again a matter of interest and research. In the last decade over 20 research studies have been published, showing new endemic areas for R. rickettsii, as well as the description of new rickettsial species in Colombia. PMID:27074327

    This essay will analyse early attempts to base anthropology on the theoretical model provided by the emerging synthetic Darwinism of the 1940s. In the first section we will investigate the historical context of the publication of one of the central documents of synthetic Darwinism in Germany: Gerhard Heberer's Die Evolution der Organismen (1943). Anthropology was covered extensively in this book. The second section will give an impression of the live and work of the five anthropologists represented in Heberer's book: Christian von Krogh, Wilhelm Gieseler, Otto Reche, Hans Weinert, and Gerhard Heberer. The third part of our paper will clarify whether these anthropologists shared a common theoretical outlook with the founders of synthetic Darwinism, and to what degree they were committed to the racial ideas of the Third Reich.

    1975-01-01

    The occupational injury and fatality experience during 32 years of the development of the atomic energy industry under the direction of the Atomic Energy Commission (AEC) and its predecessor, the Manhattan Engineering District, is reviewed. Data are included on the cause of all accidents, including fires and transportation accidents, and the cost of AEC property damage. Fatalities of AEC and contractor personnel from all causes during the 32-year period totaled 321, of which 184 occurred in construction; 121 in AEC operations such as production, research, and services; and 16 in Government functions. There were 19,225 lost-time injuries attributable to all accidental causes, or a 32-year frequency rate of 2.75 based on the number of injuries per million man-hours. There were six deaths attributable to nuclear causes, thee of which were due to blast and flying missiles and three caused by whole-body radiation exposure. Forty-one workers were involved in lost-time radiation accidents, of whom 26 showed clinical manifestations attributable to radiation, resulting in permanent partial-disability of three workers and the loss of a digit by four workers, while the others did not develop evidence of radiation injury

    Full Text Available Creating an effective insulation envelope of the building is possible only using high-quality materials, preserving their characteristics both in the early stages of operation, and for the whole billing period. It is an important opportunity to assess the thermal insulation properties and predict its changes over time directly in the conditions of the construction site. The products based on mineral fibers (rock and glass wool, basalt fiber are the most widely used type of insulating materials in the domestic construction. Therefore, the operational stability valuation methods must be primarily created for this group of products. The methodology for assessing the thermal insulation properties includes two main components: testing equipment and methodology for assessing the operational stability. The authors tested the methodology of the accelerated testing and prediction of durability for mineral wool products of laminated, corrugated and volume-oriented structures. The test results give good convergence with the methods recommended by the building regulations. Application of thermal insulation materials are an effective way to form the thermal envelope of the building, reducing energy costs and increasing the durability of building structures. The material properties are determined by their structure, which is formed during the technological impacts.

  5. Operational costs induced by fluctuating wind power production in Germany and Scandinavia

    Adding wind power generation in a power system changes the operational patterns of the existing units due to the variability and unpredictability of wind power production. For large amounts of wind power production the expectation is that the operational costs of the other power plants will increase due to more operation time in part-load and more start-ups. The change in operational costs induced by the wind power production can only be calculated by comparing the operational costs in two power system configurations: with wind power production and with alternative production having properties like conventional production, i.e. being predictable and less variable. The choice of the characteristics of the alternative production is not straight forward and will therefore influence the operational costs induced by wind power production. This paper presents a method for calculating the change in operational costs due to wind power production using a stochastic optimization model covering the power systems in Germany and the Nordic countries. Two cases of alternative production are used to calculate the change in operational costs namely perfectly predictable wind power production enabling calculation of the costs connected to unpredictability, and constant wind power production enabling calculation of the operational costs connected to variability of wind power production. A 2010 case with three different wind power production penetration levels is analysed in the paper. (au)

    1991-01-01

    The Trans-Alaska Pipeline was the object of perhaps the most passionately fought conservation battle in the U.S. Although numerous authors documented the pipeline construction during its construction, there is, surprisingly, no previous scholarly treatment of this event written by an historian. Coates is an environmental historian who views the most interesting aspect of the controversy to be open-quote its relationship to earlier engineering projects and technological innovations in Alaska and the debates that accompanied them.close quotes Thus, he describes how the conservationist and environmental ideas arose during numerous earlier major Alaskan projects and controversies, including the Alaska Highway (1938-41), Canol Pipeline (1943-45), exploration of Naval Petroleum Reserve Number Four (Pet 4, 1944-1953), DEWline (1953-57), oil development in the Kenai National Moose Range (1957-58), statehood (1958), the creation of the Arctic Wildlife Refuge (1960), Project Chariot (1958-63), and Rampart Dam (1959-67). The history starts with the acquisition of Alaska in 1867 and finishes about the time of the Valdez oil spill in 1989

    2015-06-01

    This paper gives a historical account of the early years (1953-1983) of extended irreversible thermodynamics (EIT). The salient features of this formalism are to upgrade the thermodynamic fluxes of mass, momentum, energy, and others, to the status of independent variables, and to explore the consistency between generalized transport equations and a generalized version of the second law of thermodynamics. This requires going beyond classical irreversible thermodynamics by redefining entropy and entropy flux. EIT provides deeper foundations, closer relations with microscopic formalisms, a wider spectrum of applications, and a more exciting conceptual appeal to non-equilibrium thermodynamics. We first recall the historical contributions by Maxwell, Cattaneo, and Grad on generalized transport equations. A thermodynamic theory wide enough to cope with such transport equations was independently proposed between 1953 and 1983 by several authors, each emphasizing different kinds of problems. In 1983, the first international meeting on this theory took place in Bellaterra (Barcelona). It provided the opportunity for the various authors to meet together for the first time and to discuss the common points and the specific differences of their previous formulations. From then on, a large amount of applications and theoretical confirmations have emerged. From the historical point of view, the emergence of EIT has been an opportunity to revisit the foundations and to open new avenues in thermodynamics, one of the most classical and well consolidated physical theories.

    Glove boxes are used in the Transuranium Processing Plant (TRU) at Oak Ridge National Laboratory for (1) completing the final chemical processing steps to isolate and purify the transplutonium elements, (2) packaging transplutonium elements for shipment, (3) preirradiation and postirradiation processing of samples used to produce special transplutonium isotopes in the High Flux Isotope Reactor (HFIR), and (4) conducting special projects, which include providing highly purified transplutonium products in special chemical forms and/or in experimental devices as requested by researchers. During 20 years of operation, the quantities of transplutonium elements produced, and thus the amount of radioactivity handled, have continually increased. At the same time, substantial effort has been expended to reduce personnel radiation exposures. Equipment and techniques have been developed to maintain the desired operational capabilities in the glove boxes while keeping radiation exposures to operating personnel as low as reasonably achievable. Developments have included the design and fabrication of product handling and collection devices, product storage containers, and laminated exterior shields of lead glass, lead acrylic, acrylic sheets, polyethylene, and lead

    We study the possible contributions of dimension six operators containing fermion fields to Higgs production at a 500 GeV or 1 TeV e + e - linear collider. We show that--depending on the production mechanism--the effects of such operators can be kinematically enhanced relative to standard model (SM) contributions. We determine constraints on the operator coefficients implied by existing precision electroweak measurements and the scale of neutrino mass. We find that even in the presence of such constraints, substantial deviations from SM Higgs production cross sections are possible. We compare the effects of fermionic operators with those associated with purely bosonic operators that have been previously discussed in the literature

    1998-12-31

    To achieve vertical connectivity with all the layers, and thus long term sustained productivity in a highly stratified reservoir, a one run underbalanced perforating operation was considered necessary. Due to coiled tube limitations in this deep (5136 m along hole, 3700 m true vertical depth, with a maximum deviation of 89 degrees), high pressure well a hydraulic workover unit (HWU) was selected to deploy and retrieve the guns. The operation is considered a world record since this is the longest section (total gross interval of 1026 m perforated) of guns conveyed, fired underbalanced and deployed out of a live well. It is concluded that the improved productivity more than justified the additional time, effort and expenditure; considering the full life cycle of the well it is readily apparent that the operation was an economic and technical success. Details of the considerations leading to the perforating technique selection, the planning and the execution of the operation, and the validation of the technique in terms of productivity gains, are provided. 13 refs., 7 figs.

    2014-01-01

    The idea of colliding two particle beams to fully exploit the energy of accelerated particles was first proposed by Rolf Wideröe, who in 1943 applied for a patent on the collider concept and was awarded the patent in 1953. The first three colliders — AdA in Italy, CBX in the US, and VEP-1 in the then Soviet Union — came to operation about 50 years ago in the mid-1960s. A number of other colliders followed. Over the past decades, colliders defined the energy frontier in particle physics. Different types of colliers — proton–proton, proton–antiproton, electron–positron, electron–proton, electron-ion and ion-ion colliders — have played complementary roles in fully mapping out the constituents and forces in the Standard Model (SM). We are now at a point where all predicted SM constituents of matter and forces have been found, and all the latest ones were found at colliders. Colliders also play a critical role in advancing beam physics, accelerator research and technology development. It is timel...

    Nowadays, more and more manufacturing firms have started to implement lean production system in their operations. Lean production viewed as one of the mechanism to maintain the organisation's position and to compete globally. However, many fail to apply the lean concepts successfully in their operations. Based on previous studies, implementation of lean production in the manufacturing industry is more focused on the relationship between Lean and Operational Performance of one dimension only. Therefore, this study attempted to examine the relationship between Lean Production (LP) and Operational Performance in 4 dimensions which are quality, delivery, cost and flexibility. This study employed quantitative study using questionnaires. Data was collected from 50 manufacturing industries. The data was analysed using Statistical Package for Social Science (SPSS) 22.0. This study is hoped to shed new understanding on the concept of Lean Production (LP) in regards of Operational Performance covering the 4 dimensions.

    2018-03-01

    The multicriteria rapid assessment method of techno-economic parameters of new products is developed. It avoids expensive engineering changes during the operational stages through the analysis of external and internal factors at an early stage in the design that affect the maintainability and manufacturability of the product. The expert selection of the initial multitude of indicators from the five enlarged criteria groups and their subsequent pairwise comparison allow one to distinguish the complex compliance criteria of product design with the average and optimum values of the operational effectiveness. The values comparison provides an opportunity to decide on the continuation of the process for designing and preparation of the product manufacture.

  10. Operating experience in reprocessing

    1983-01-01

    Since 1953, reprocessing has accumulated 180 years of operating experience in ten plants, six of them with 41 years of operation in reprocessing oxide fuel from light water reactors. After abortive, premature attempts at what is called commercial reprocessing, which had been oriented towards the market value of recoverable uranium and plutonium, non-military reprocessing technologies have proved their technical feasibility, since 1966 on a pilot scale and since 1976 on an industrial scale. Reprocessing experience obtained on uranium metal fuel with low and medium burnups can now certainly be extrapolated to oxide fuel with high burnup and from pilot plants to industrial scale plants using the same technologies. The perspectives of waste management of the nuclear power plants operated in the Federal Republic of Germany should be viewed realistically. The technical problems still to be solved are in a balanced relationship to the benefit arising to the national economy out of nuclear power generation and can be solved in time, provided there are clearcut political boundary conditions.

    It has been always observed that the release of fission products increase during refueling operations. At RAPP-3 and 4 an attempt has been made to follow-up the change in fission products activity release at each stage of refueling operation and quantification of concentrations of various radionuclides. This exercise was also extended to refueling operation of the channels containing suspected failed fuel. A level of FPNG ( 133 Xe) was observed to increase by a factor of about 10-40 during refueling of failed channel as compared to healthy channel. It can be concluded that by monitoring FPNG levels in exhaust status of the healthiness of spent fuel can be found out. This report discusses in detail the experiment conducted for this purpose.

The characteristic of agent and operational developments NKGB–MGB–KGB of the USSR against the so-called «catacomb Church», as a form of religious and social protest against aggressive atheistic policy of the Communist authorities, infringement of the rights of believers. The basic forms and methods of intelligence and operational activities of the security organs, aimed at creating informer positions in the environment of the communities of the TOC, making the split in the ranks of the adepts of secret religious sects, the collection of «compromising material» as the basis for the application of harsh repressive measures against the movement of the TOC. The authors pay special attention to the organization and personnel of units of the NKGB–MGB–KGB, engaged, according to the terminology, «the struggle with the Church-sectarian counterrevolution» and «Church-monarchist underground», a leading representative of which was considered in the TOC, particularly active in Chernihiv, Sumy, and Kharkiv oblasts of the Ukrainian SSR and the Donbass, and also in the neighboring regions of the Russian black soil region and the North Caucasus. Given the author’s periodization of the development of the catacomb movement, highlights the historical conditions of its creation and release in the USSR. Through the prism of intelligence documents examines the liturgical aspect of the TOC, its governing structure, forms of secrecy and concealment from the prosecution authorities, the position of the catacomb members in relation to social life and social structure in the USSR.

    Within KNMI a new fully automated system for monitoring the KNMI operational data production systems is being developed: PRISMA (PRocessflow Infrastructure Surveillance and Monitoring Application). Currently the KNMI operational (24/7) production systems consist of over 60 applications, running on different hardware systems and platforms. They are interlinked for the production of numerous data products, which are delivered to internal and external customers. Traditionally these applications are individually monitored by different applications or not at all; complicating root cause and impact analysis. Also, the underlying hardware and network is monitored via an isolated application. Goal of the PRISMA system is to enable production chain monitoring, which enables root cause analysis (what is the root cause of the disruption) and impact analysis (what downstream products/customers will be effected). The PRISMA system will make it possible to reduce existing monitoring applications and provides one interface for monitoring the data production. For modeling and storing the state of the production chains a graph database is used. The model is automatically updated by the applications and systems which are to be monitored. The graph models enables root cause and impact analysis. In the PRISMA web interface interaction with the graph model is accomplished via a graphical representation. The presentation will focus on aspects of: • Modeling real world computers, applications, products to a conceptual model; • Architecture of the system; • Configuration information and (real world) event handling of the to be monitored objects; • Implementation rules for root cause and impact analysis. • How PRISMA was developed (methodology, facts, results) • Presentation of the PRISMA system as it now looks and works

    The development of the common market for coal is traced from its creation on 10 February 1953 by the High Authority of the European Coal and Steel Community up to the recent past. Describes the position assumed by coal in the Community's energy supply, the changes on the individual markets for solid fuels and the development of the factors affecting supply, including technical progress in the Community's coal mining industry. The changes which have transformed the world energy market are also described. There follows an account of the role played by the Community, in particular the ECSC executive, in the various stages of development of the common market in coal. Chapter 3 deals with the consolidation during the transitional period provided for in the ECSC Treaty; Chapter 4 describes the events of the coal crisis and Chapter 5 is devoted to Community energy policy since the oil crisis of 1973/74 from the coal industry's viewpoint. The appendix contains 39 tables of statistics covering all important aspects of the coal sector since the common market was established.

    The apparatus invented by Dr. Luigj Benusi in 1943, in Tirana, was a practical application of the Kowarsky technique and Ambard laws, helping in determining blood urea levels and very important to a variety of diseases, mainly kidney disorders. The apparatus was invented and prepared from very simple laboratory materials, such as glasses, test tubes, corks and volumetric cylinders. Technologically, it was based upon the determination of blood urea through hypobromite, and, among the advantages of the apparatus of Benusi, were its extreme simplicity, the smaller amount of blood needed for producing results (2 milliliters), as well as an easiest way to clean up and to manage the apparatus from a practical point of everyday use.

  19. Optimum operation of a small power production facility

    1983-09-01

    To help reduce the U.S.A.'s dependence on imported oil for electrical power generation, the 1978 National Energy Act established regulations to promote construction and operation of cogeneration and small power production facilities. Many of these facilities are presently under construction, with a great number planned. This paper examines the operation of a small power production facility with on-site generation and storage, on-site use, and connection to an electric utility grid system for the purpose of both selling excess power and buying power. It is assumed that the buying and selling price of electricity varies frequently during the day and that the relevant price and demand data may be accurately projected into the near future. With this system description, a mathematical model is formulated and solved by linear programming to obtain a series of periodic buy and sell decisions so as to maximize the profit from operating the small power production facility. Results are presented to illustrate the methodology for determining potential profits.

  20. Unlimited productivity: your operation can achieve it

    Bovino, V R

    1986-10-01

    Most mines substantially underestimate their real potential. The market for coal is global and people consider the problems are caused by uncontrolled production of foreign coal, however part of the problem is productivity, that is the ability to produce tons of coal in a cost-effective way, rather than production. Any operation can deliver unlimited productivity by developing the resource within their employees. This paper discusses the areas where the industry has gone wrong, including bureaucracy, blind faith in price rises, wages, adversaries; tradition, narrow job characteristics, conformance over performance for employees, management, money, self-limitations and benefit plans. It also describes three basic ways of improving productivity. These are positive management practices, employee participation and shared rewards.

  1. Study of the productivity evolution in the operation of CLAB

    SKB shall every year, on behalf of the power companies, send SKI a cost calculation for spent fuel handling and dismantling of the Swedish nuclear power plants. SKI has tried to investigate the future impact which the growth of money in the Nuclear Waste Fund might give in relation to the change of consumer price index, CPI. The long term yield of the Fund has been related to the change of CPI, as the bigger part of the fund money has been invested in real interest rate bonds. The cost development has been studied by SKI with an index named 'KBS-3-index', which is a basket of weighted factor price indexes made out of the SKB programme. Since 1986 and up to 1998, the KBS-3-index has increased about 14% more than CPI. If this discrepancy should continue during the whole period when Fund money should be available, the Fund would be insufficient. But the difference between KBS-3-index and CPI might be eliminated due to a future productivity development. At the moment, SKI has no knowledge about future productivity development in the SKB programme. A closer analysis of the facilities operated by SKB is therefore important. Nearest to study is the productivity at the operation of CLAB, Central Interim Storage Facility for Spent Nuclear Fuel. The work in CLAB is receiving and storing of spent nuclear fuel and core components and reloading from normal to compact cassettes. The consumption of all production factors can be measured in money. Here the total production factors are defined as the sum of the annual operation costs and the sum of annuities for reinvestments during the year. The development for total productivity is slightly increasing. Normal for a new business is that the productivity rises sharply in the beginning. Here the productivity is slightly decreasing in the beginning, and then rising, sinking and at last a sharp rising. Project compact storing was finished in 1992, and relocation to compact cassettes started in 1993. This is said to be the reason for

  2. Conformal four point functions and the operator product expansion

    2001-01-01

    Various aspects of the four point function for scalar fields in conformally invariant theories are analysed. This depends on an arbitrary function of two conformal invariants u,v. A recurrence relation for the function corresponding to the contribution of an arbitrary spin field in the operator product expansion to the four point function is derived. This is solved explicitly in two and four dimensions in terms of ordinary hypergeometric functions of variables z,x which are simply related to u,v. The operator product expansion analysis is applied to the explicit expressions for the four point function found for free scalar, fermion and vector field theories in four dimensions. The results for four point functions obtained by using the AdS/CFT correspondence are also analysed in terms of functions related to those appearing in the operator product discussion

    2012-07-01

    From the introduction: The Remote Operations in Oklahoma Intended for Education (ROOKIE) project is a remote field laboratory constructed as a part of this research project. ROOKIE was initiated to provide data in research on production optimization of low productivity gas wells. In addition to this, ROOKIE is used as a teaching tool. Much of the remote operations technology used in the ROOKIE project has been used by the industry for several decades. The first use of remote data acquisition in Oklahoma was in 1989, as described by Luppens [7]. Even though this, for the most part, is old technology, the ROOKIE project is the first remote operations project set up with research and teaching as the main focus. This chapter will discuss the process of establishing the remote field laboratory and the data storage facilities. Results from the project will also be discussed. All testing, instrumentation installation, and modifications to the wells discussed in this chapter was performed by the author. The communication system between the well and NTNU, and the storage database was installed and configured by the author.(Author)

    The Cullen Enquiry into the Piper Alpha disaster in the U.K. North Sea recommended that an operator should formally present it's company Management System and demonstrate how safety is achieved throughout the life cycle of a platform, from design through operation to abandonment. Brunei Shell Petroleum has prepared a corporate level Safety Management System. As part of Safety Case work, the corporate system is being extended to include the development of specific Management Systems with particular emphasis on offshore production operations involving integrated oil and gas facilities. This paper will describe the development of Management Systems, which includes an intensive Business Process Analysis and will comment upon it's applicability and relationship to ISO 9000. The paper will further describe the applicability and benefits of Management Systems and offer guidance on required effort. The paper will conclude that development of structured Management Systems for safety critical business processes is worthwhile but prioritization of effort will be necessary. As such the full adoption of Management Systems will be directional in nature

    The by-product activity arising from atom bomb test was investigated in Heidelberg by a filtration method during March 1953. The measurement of the activity on the filter was accomplished by a cylindrical ..beta..-counter. The decay was proportional to t/sup -/(1 + x), where x is of the order of magnitude of 0.1, and thus approaches t/sup -1/. The time of explosion can be determined by extrapolation of the reciprocal activity as a function of time.

    A suite of operational land products has been produced as part of NOAA's Joint Polar Satellite System (JPSS) program to support a wide range of operational applications in environmental monitoring, prediction, disaster management and mitigation, and decision support. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar-orbiting Partnership (NPP) and the operational JPSS satellite series forms the basis of six fundamental and multiple additional added-value environmental data records (EDRs). A major recent improvement in the land-based VIIRS EDRs has been the development of global gridded products, providing a format and science content suitable for ingest into NOAA's operational land surface and coupled numerical weather prediction models. VIIRS near-real-time Green Vegetation Fraction is now in the process of testing for full operational use, while land surface temperature and albedo are under testing and evaluation. The operational 750m VIIRS active fire product, including fire radiative power, is used to support emission modeling and air quality applications. Testing the evaluation for operational NOAA implementation of the improved 375m VIIRS active fire product is also underway. Added-value and emerging VIIRS land products include vegetation health, phenology, near-real-time surface type and surface condition change, and other biogeophysical variables. As part of the JPSS program, a global soil moisture data product has also been generated from the Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on the GCOM-W1 (Global Change Observation Mission - Water 1) satellite since July 2012. This product is included in the blended NESDIS Soil Moisture Operational Products System, providing soil moisture data as a critical input for land surface modeling.

    2008-12-01

    Implementation of initiatives to increase anesthesia group productivity depends not just on anesthesia groups, but on operating room (OR) nursing administration. OR nursing directors may encourage organizational change based on the needs of their hospitals and nurses. These changes may differ from those that would increase the anesthesia group's productivity. We assessed reward structures using (A) letters of nomination for the "OR Manager of the Year" award offered annually by the publication OR Manager, and (B) data from a salary/career survey of OR directors by the same publication. (A) There were 164 nomination letters submitted from 2004 through 2007 for 45 nominees. The letters contained n = 2659 full sentences and n = 50,821 words. We systematically created a list of 36 terms related to finance, profit, and productivity. We also analyzed the frequency of use of these terms relative to the use of the 15 most common relationship-oriented terms (e.g., compassion, encourage, mentor, and respect). (B) The salary/career survey's questions relevant to anesthesia group productivity had responses from 303 US OR directors, 97% of whom were nurses. We tested the strength of the relationship between the budget responsibility of the OR nursing director and his or her annual salary. (A) 2.6% of sentences in the nomination letters included at least one term related to profit and productivity (95% confidence interval 2.0%-3.2%). Relationship-oriented terms were 9.0 times more prevalent (95% confidence interval 7.1-11.4). (B) There was statistically significant positive proportionality between the OR nursing director's operational budget (including personnel) and his or her salary (Pearson r = 0.64, P time and OR nursing labor costs. Resulting decisions can differ from those that would increase the productivity (profit) of the anesthesia group. Anesthesia groups need to champion initiatives to increase anesthesia productivity, while being sensitive to institutional

    Dr. Franjo (Franz) Kresnik (born Wien 1869 - died Rijeka 1943) was an excellent physician and a Central European intellectual, a bohemian mind whose two loves in life made him very special. His passions were medicine and violin making. Most of his life was spent in Susak (now a part of Rijeka, Croatia), where he worked, played music and studied the art of making stringed instruments. He visited Cremona on several occasions and studied a number of violins, drawings and tools made and used by old masters. For his profound knowledge of Cremonese violin making the Italians dubbed him "Uomo che legge violini" (The Man Who Can Read Violins). In his workshop he made fifty-two violins, two violas, two cellos and a string quartet. Some of these instruments are still played in Europe and America. The remaining violins and possessions (tools, manuscripts, drawings, literature and countless diplomas and certificates) have been kept in a memorial room at the Maritime and History Museum of the Croatian Littoral in Rijeka. In addition, a street near the Faculty of Medicine in Rijeka is named after Franjo Kresnik.

    Brucellosis was a common human and livestock disease caused by Brucella strains, the category B priority pathogens by the US Center for Disease Control (CDC). Identified as a priority disease in human and livestock populations, the increasing incidence in recent years in China needs urgent control measures for this disease but the molecular background important for monitoring the epidemiology of Brucella strains at the national level is still lacking. A total of 600 Brucella isolates collected during 60 years (from 1953 to 2013) in China were genotyped by multiple locus variable-number tandem repeat analysis (MLVA) and the variation degree of MLVA11 loci was calculated by the Hunter Gaston Diversity Index (HGDI) values. The charts and map were processed by Excel 2013, and cluster analysis and epidemiological distribution was performed using BioNumerics (version 5.1). The 600 representative Brucella isolates fell into 104 genotypes with 58 singleton genotypes by the MLVA11 assay, including B. melitensis biovars 2 and 3 (five main genotypes), B. abortus biovars 1 and 3 (two main genotypes), B. suis biovars 1 and 3 (three main genotypes), and B. canis (two main genotypes) respectively. While most B. suis biovar 1 and biovar 3 were respectively found in northern provinces and southern provinces, B. melitensis and B. abortus strains were dominant in China. Canine Brucellosis was only found in animals without any human cases reported. Eight Brucellosis epidemic peaks emerged during the 60 years between 1953 and 2013: 1955 - 1959, 1962 - 1969, 1971 - 1975, 1977 - 1983, 1985 - 1989, 1992 - 1997, 2000 - 2008 and 2010 - 2013 in China. Brucellosis has its unique molecular epidemiological patterns with specific spatial and temporal distribution according to MLVA. IDOP-D-16-00101.

    Full Text Available In the article the author performs a hermeneutic analysis of cultural context, i.e. investigation of media texts interpretation, cultural and historical factors influencing the views of the agency / author of a media text and the audience, on specific examples of positive image of the USSR and soviet characters in American films in 1943-1945. The author bears in mind that the hermeneutic analysis of a media text comprehension involves a comparison with a historical, cultural tradition and reality; insight into its logic; comparison of media images in historical and cultural contexts combined with the historical, hermeneutical analyses of the structural, plot, ethical, ideological and iconographic / visual analyses of media stereotypes and media text characters. The analysis of these media texts, in the author's opinion, is especially important for media education of future historians, culture experts, art critics, social scientists, philologists, psychologists and teachers.

    We discuss a general method of constructing the products of composite operators using the exact renormalization group formalism. Considering mainly the Wilson action at a generic fixed point of the renormalization group, we give an argument for the validity of short-distance expansions of operator products. We show how to compute the expansion coefficients by solving differential equations, and test our method with some simple examples.

The Minerals Management Service continued receiving reports of more damage. By the end of the day Sept. 8, MMS had received reports of damage to 83 pipeline segments and 193 platforms and satellite installations. Damage reports listed 112 installations with structural damage, 13 platforms toppled and five leaning, and 30 satellite platforms toppled and 33 leaning. But despite the extent of damage the storm inflicted on oil and gas installations in the gulf, it pales in comparison to the misery and suffering the storm caused in Florida and Louisiana, an oil company official said

    2016-01-01

    This book provides an overview of intelligent decision-making techniques and discusses their application in production and retail operations. Manufacturing and retail enterprises have stringent standards for using advanced and reliable techniques to improve decision-making processes, since these processes have significant effects on the performance of relevant operations and the entire supply chain. In recent years, researchers have been increasingly focusing attention on using intelligent techniques to solve various decision-making problems. The opening chapters provide an introduction to several commonly used intelligent techniques, such as genetic algorithm, harmony search, neural network and extreme learning machine. The book then explores the use of these techniques for handling various production and retail decision-making problems, such as production planning and scheduling, assembly line balancing, and sales forecasting.

    Full Text Available Introducción: Los indicadores de salud en Colombia han cambiado más en los últimos 60 años que en los anteriores cuatro y medio siglos. Este trabajo analiza las estadísticas vitales de salud de Colombia desde 1953 hasta 2013. Métodos: Se consultaron bases de datos del Departamento Administrativo Nacional de Estadística, años 1985 a 2013, y registros de defunción de 1953 a 1981, en libros estadísticos. Los datos obtenidos fueron procesados para la obtención de gráfi cas y pirámides poblacionales. Resultados: La distribución por edad de la población colombiana ha mostrado una reducción de la población infantil, con un aumento de los adultos, particularmente los adultos mayores. En cuanto a la mortalidad infantil, hace medio siglo más de cincuenta mil niños morían cada año antes de cumplir cinco años de vida, hoy mueren alrededor de siete mil niños por año. La mortalidad materna ha disminuido, sin alcanzarse el objetivo del milenio propuesto. Por varios años, la primera causa de muerte fueron los homicidios, posteriormente pasaron a un segundo lugar después de las enfermedades isquémicas del corazón. Las morbimortalidad atribuible a enfermedades crónicas ha aumentado, la enfermedad cardiovascular es la principal causa atribuible de muerte en los colombianos. Discusión: Este estudio muestra los cambios en mortalidad que corresponden a una transición epidemiológica acelerada. Las inequidades en salud entre las diferentes regiones del país no se refl ejan bien en estas cifras globales. Estos datos pueden ser proyectados hacia el futuro, con un aumento de la edad promedio y de la prevalencia de las enfermedades crónicas.

    Full Text Available Traditional construction planning, which depends on historical data and heuristic modification, prevents the integration of managerial details such as productivity dynamics. Specifically, the distance between planning and execution brings cost overruns and duration extensions. To minimize variations, this research presents a Building Information Modeling (BIM-integrated simulation framework for predicting productivity dynamics at the construction planning phase. To develop this framework, we examined critical factors affecting productivity at the operational level, and then forecast the productivity dynamics. The resulting plan includes specific commands for retrieving the required information from BIM and executing operation simulations. It consists of the following steps: (1 preparing a BIM model to produce input data; (2 composing a construction simulation at the operational level; and (3 obtaining productivity dynamics from the BIM-integrated simulation. To validate our framework, we applied it to a structural steel model; this was due to the significance of steel erections. By integrating BIM with construction operation simulations, we were able to create reliable construction plans that adapted to project changes. Our results show that the developed framework facilitates the reliable prediction of productivity dynamics, and can contribute to improved schedule reliability, optimized resource allocation, cost savings associated with buffers, and reduced material waste.

    Full Text Available A performance monitoring study of an electric rope shovel operating in an open pit coal mine was conducted. As the mining industry moves toward higher productivity, profitability and predictability, the need for more reliable, productive and efficient mining shovels increases. Consequently, it is critical to study the productivity of these machines and to understand the effect of different operational parameters on that. In this paper a clustering analysis is performed to classify shovel digging effort and behaviour based on digging energy, dig time and payload per pass. Then the influence of the operator on the digging efficiency and productivity of the machine is analyzed with a focus on operator technique during digging. A statistical analysis is conducted on different cycle time components (dig time, swing time, return time for different operators. In addition to time components, swing and return angles as well as loading rate and mucking rate are observed and analyzed. The results of this study help to understand the effect of different operators on the digging productivity of the shovel and then to set the best operator practice.

    The Peach Bottom high-temperature, gas-cooled reactor began operation on 1 June 1967 and continued power production until 9 October 1969, accumulating 452 equivalent full power days (EFPD) operation. After reload, power production with Core 2 began 14 July 1970 and terminated 31 October 1974 after 897 EFPD operation. Surveillance of fission product release and behaviour was intensified during Core 2 operation to permit a wider range of measurements to be made. In addition to monitoring the noble gas content of the fuel element purge system and the coolant circuit, the programme was extended to include measurements of radioactive and other condensible species (including dust) entering or exiting the core and steam generator, and of surface concentrations of gamma-emitting nuclides deposited on the primary coolant surfaces. These data, which were obtained over the operating period April 1971 - October 1974, are summarized and discussed. The data demonstrate that caesium behaviour in the coolant circuit during the first two-thirds of Core 2 life was primarily governed by caesium released during Core 1 operation. The data also indicate that whereas the steam generator surfaces attenuate molecular caesium concentrations in the coolant, the dust-borne component is remarkably persistent. Driver fuel elements were removed from the reactor after 385 EFPD, 701 EFPD, and at end-of-life. These fuel elements are at various stages of an intensive post-irradiation examination. Some of the axial and radial concentration profiles of fission products which have been obtained are likewise presented. Although these profiles indicate varied fission product behaviour, the observations can in general be qualitatively described on the basis of the operational histories of the fuel elements. (author)

    Full Text Available Historical experience in the Great Patriotic War and analysis of the main events, such as “the radical turn” and the battle for Stalingrad, are relevant to researchers not only due to anniversary of the War but also because of ongoing projects of unprecedented scale. Peculiarities of management and definition of economic, social and political resources used for recovery of the damage caused by hostilities and occupation of USSR is of academic interest. The article is devoted to studying the organization of goal-orientated credit programs on restoration in 1943- 1944 in the post-ocupation period. The author analyses the work of the USSR bank system in providing loans for restoring the agricultural potential of the region, and also implementing social policies for securing all categories of agrarian population. Work of credit institutions played a great part not only in restoring of agricultural production, but also in providing a real assistance to all farm buildings destroyed during the Great Patriotic War and to individual agricultural sector on the whole. Restoration of the Stalingrad region is examined in the light of using state and organising, financial and credit, moral and patriotic resources of the USSR in 1943–1944. In order to overcome the consequences of occupation, additional state financing was required, which was used to restore some strategically significant institutions, to reevacuate some industrial equipment, to increase the number of cattle, to return specialists and to accomodate them, to create industrial infrastructure, to rebuild demolished buildings and so on. Methods and means used to gain the set goals were various: from well-organised government institutions to stupendous participation of the nation in different actions by national input, war loans and taxes. Taking under consideration the chronically shortage of state budget, the government relied on local initiatives towards raising money from hinterland

    2014-06-01

    To determine the cause of death of prisoners of war during the Korean War (1950-1953), death certificates or medical records were analyzed. Out of 7,614 deaths, 5,013 (65.8%) were due to infectious diseases. Although dysentery and tuberculosis were the most common infectious diseases, parasitic diseases had caused 14 deaths: paragonimiasis in 5, malaria in 3, amoebiasis in 2, intestinal parasitosis in 2, ascariasis in 1, and schistosomiasis in 1. These results showed that paragonimiasis, malaria, and amoebiasis were the most fatal parasitic diseases during the early 1950s in the Korean Peninsula. Since schistosomiasis is not endemic to Korea, it is likely that the infected private soldier moved from China or Japan to Korea.

    An innovative model for measuring the operational productivity of medication order management in inpatient settings is described. Order verification within a computerized prescriber order-entry system was chosen as the pharmacy workload driver. To account for inherent variability in the tasks involved in processing different types of orders, pharmaceutical products were grouped by class, and each class was assigned a time standard, or "medication complexity weight" reflecting the intensity of pharmacist and technician activities (verification of drug indication, verification of appropriate dosing, adverse-event prevention and monitoring, medication preparation, product checking, product delivery, returns processing, nurse/provider education, and problem-order resolution). The resulting "weighted verifications" (WV) model allows productivity monitoring by job function (pharmacist versus technician) to guide hiring and staffing decisions. A 9-month historical sample of verified medication orders was analyzed using the WV model, and the calculations were compared with values derived from two established models—one based on the Case Mix Index (CMI) and the other based on the proprietary Pharmacy Intensity Score (PIS). Evaluation of Pearson correlation coefficients indicated that values calculated using the WV model were highly correlated with those derived from the CMI-and PIS-based models (r = 0.845 and 0.886, respectively). Relative to the comparator models, the WV model offered the advantage of less period-to-period variability. The WV model yielded productivity data that correlated closely with values calculated using two validated workload management models. The model may be used as an alternative measure of pharmacy operational productivity. Copyright © 2015 by the American Society of Health-System Pharmacists, Inc. All rights reserved.

    The realization of an end-to-end integrated continuous lab-scale process for monoclonal antibody manufacturing is described. For this, a continuous cultivation with filter-based cell-retention, a continuous two column capture process, a virus inactivation step, a semi-continuous polishing step (twin-column MCSGP), and a batch-wise flow-through polishing step were integrated and operated together. In each unit, the implementation of internal recycle loops allows to improve the performance: (a) in the bioreactor, to simultaneously increase the cell density and volumetric productivity, (b) in the capture process, to achieve improved capacity utilization at high productivity and yield, and (c) in the MCSGP process, to overcome the purity-yield trade-off of classical batch-wise bind-elute polishing steps. Furthermore, the design principles, which allow the direct connection of these steps, some at steady state and some at cyclic steady state, as well as straight-through processing, are discussed. The setup was operated for the continuous production of a commercial monoclonal antibody, resulting in stable operation and uniform product quality over the 17 cycles of the end-to-end integration. The steady-state operation was fully characterized by analyzing at the outlet of each unit at steady state the product titer as well as the process (HCP, DNA, leached Protein A) and product (aggregates, fragments) related impurities. © 2017 American Institute of Chemical Engineers Biotechnol.

    Depictions of Caucasian women in the mainstream media have become increasingly thinner in size and straighter in shape. These changes may be inconsistent with the growing influence of African American beauty ideals, which research has established as more accepting of larger body sizes and more curvaceous body types than Caucasians. The present study looked at trends in the portrayal of African American women featured in JET magazine from 1953 to 2006. Beauty of the Week (BOW) images were collected and analyzed to examine body size (estimated by independent judges) and body shape (estimated by waist-to-hip ratio). We expected body sizes to increase and body shapes to become more curvaceous. Results revealed a rise in models' body size consistent with expectations, but an increase in waist-to-hip ratio, contrary to prediction. Our findings suggest that the African American feminine beauty ideal reflects both consistencies with and departures from mainstream cultural ideals. Copyright © 2010 Elsevier Ltd.

  20. A cost prediction model for machine operation in multi-field production systems

    Directory of Open Access Journals (Sweden)

    Alessandro Sopegno

    Full Text Available ABSTRACT Capacity planning in agricultural field operations needs to give consideration to the operational system design which involves the selection and dimensioning of production components, such as machinery and equipment. Capacity planning models currently onstream are generally based on average norm data and not on specific farm data which may vary from year to year. In this paper a model is presented for predicting the cost of in-field and transport operations for multiple-field and multiple-crop production systems. A case study from a real production system is presented in order to demonstrate the model’s functionalities and its sensitivity to parameters known to be somewhat imprecise. It was shown that the proposed model can provide operation cost predictions for complex cropping systems where labor and machinery are shared between the various operations which can be individually formulated for each individual crop. By so doing, the model can be used as a decision support system at the strategic level of management of agricultural production systems and specifically for the mid-term design process of systems in terms of labor/machinery and crop selection conforming to the criterion of profitability.

This vehavior in turn controls the high-Q 2 limit of hadronic form factors. In particular, we relate each anamalous dimension of the nonsinglet structure functions to a corresponding logarithmic correction factor to the nominal αsub(s)(Q 2 )/Q 2 fall off of meson form factors. Unlike the case of deep inelastic lepton-hadron scattering, the operator product necessary here involves extra terms which do not contribute to forward matrix elements. (orig.)

    Full Text Available Abstract Background Random samples of 50-year-old men living in Gothenburg have been examined every 10th year since 1963 with a focus on cardiovascular risk factors. The aims of the study were to acquire up-to-date information about risk factors in the fifth cohort of 50-year-old men and women, to re-examine those who were 50 years of age in 1993, and to analyse the prevalence of the metabolic syndrome (MetSyn using different definitions. Methods A random sample of men and women born in 1953 were examined in 2003–2004 for cardiovascular risk factors. Men born in 1943 and that participated in the examination in 1993 were also invited. Descriptive statistics were calculated. Results The participation rate among men and women born in 1953 was 60 and 67% respectively. Among men born in 1943, the participation rate was 87%. The prevalence of obesity was from 15 to 17% (body mass index, BMI ≥ 30 in the three samples. The prevalence of known diabetes was 4% among the 50-year-old men and 6% among the 60-year-old men, and 2% among the women. Increased fasting plasma glucose varied substantially from 4 to 33% depending on cut-off level and gender. Mean cholesterol was 5.4 to 5.5 mmol/l. Smoking was more common among women aged 50 (26% than among men aged 50 (22% and 60 years (15%. The prevalence of the MetSyn varied with the definition used: from 10 to 15.8% among the women, from 16.1 to 26% among 50-year-old men, and from 19.9 to 35% among the 60-year-old men. Only 5% of the men and women had no risk factors. Conclusion This study provides up-to-date information about the prevalence of cardiovascular risk factors and the MetSyn in middle-aged Swedish men and women. Different definitions of the MetSyn create confusion regarding which definition to use.

  4. On the renormalization of operator products: the scalar gluonic case

    In this paper we study the renormalization of the product of two operators O 1 =−(1/4)G μν G μν in QCD. An insertion of two such operators O 1 (x)O 1 (0) into a Greens function produces divergent contact terms for x→0. In the course of the computation of the operator product expansion (OPE) of the correlator of two such operators i∫ d 4 x e iqx T{ O 1 (x)O 1 (0)} to three-loop order http://dx.doi.org/10.1007/JHEP12(2012)119; http://dx.doi.org/10.1007/JHEP10(2014)169 we discovered that divergent contact terms remain not only in the leading Wilson coefficient C 0 , which is just the VEV of the correlator, but also in the Wilson coefficient C 1 in front of O 1 . As this correlator plays an important role for example in QCD sum rules a full understanding of its renormalization is desireable. This work explains how the divergences encountered in higher orders of an OPE of this correlator should be absorbed in counterterms and derives an additive renormalization constant for C 1 from first principles and to all orders in perturnbation theory. The method to derive the renormalization of this operator product is an extension of the ideas of V. Spiridonov, Anomalous dimension of g μν 2 and β-function, Preprint IYAI-P-0378 (1984). and can be generalized to other cases.

  5. A comparison of the causes, effects and aftermaths of the coastal flooding of England in 1953 and France in 2010

    Full Text Available This paper provides a comparison of the causes, effects and aftermaths of the coastal flooding that occurred on the east coast of England in 1953 and the west coast of France in 2010 that resulted in 307 and 47 deaths respectively. The causes of both events are strikingly similar. Both were caused by a combination of high tides, low atmospheric pressure, high winds and the failure of poorly maintained flood defences. In both cases the number of deaths was related to the vulnerability of the buildings and people. Buildings in the flood zones were often single storey bungalows and the people who died were mostly over 60 yr of age. Both tragedies were national disasters. The 1953 flood in England acted as a catalyst for an acceleration in flood risk management policy and practice. It resulted in: the development of a Storm Tide Warning System for the east coast of England; the setting of new design standards for coastal flood defences; increased investment in improving coastal defences; and a substantial new research effort into coastal processes, protection and forecasting. In France there has also been an episodic shift in flood risk management policy with the focus falling on: control of urban developments in areas at risk of flooding; improved coastal forecasting and warning; strengthening of flood defences; and developing a "culture of risk awareness". This paper outlines the lessons that can be learnt from the two events and provides recommendations concerning how future loss of life as a result of coastal flooding can be reduced.

    Streptomyces canuswas described in 1953 and the name was listed in the Approved List of Bacterial Names in 1980. Three years later, Streptomyces ciscaucasicus was published and the name was subsequently validated in Validation List no. 22 in 1986. On the basis of genome comparison and multilocus sequence analysis of the type strains of Streptomyces canus and Streptomyces ciscaucasicus it can now be shown that these two species despite some phenotypic differences are subjective synonyms. In such a case Rule 24 of the Bacteriological Code applies, in which priority of names is determined by the date of the original publication. Hence, we propose that S. ciscaucasicus is a later subjective synonym of S. canus.

    An emission spectrum of H216O has been recorded, with Doppler-limited resolution, at 1943 K using Hot Gas Molecular Emission (HOTGAME) spectroscopy. The wavenumber range covered is 6600 to 7050 cm-1. This work reports the analysis and subsequent assignment of close to 3700 H216O transitions out of a total of more than 6700 measured peaks. The analysis is based on the Measured Active Rotational-Vibrational Energy Levels (MARVEL) energy levels of H216O determined in 2013 and emission line intensities obtained from accurate variational nuclear-motion computations. The analysis of the spectrum yields about 1300 transitions not measured previously and 23 experimentally previously unidentified rovibrational energy levels. The accuracy of the line positions and intensities used in the analysis was improved with the spectrum deconvolution software SyMath via creating a peak list corresponding to the dense emission spectrum. The extensive list of labeled transitions and the new experimental energy levels obtained are deposited in the Supplementary Material of this article as well as in the ReSpecTh (http://www.respecth.hu) information system.

    Deep-inelastic scattering, in the laboratory and on the lattice, is most instructive for understanding how the nucleon is built from quarks and gluons. The long-term goal is to compute the associated structure functions from first principles. So far this has been limited to model calculations. In this Letter we propose a new method to compute the structure functions directly from the virtual, all-encompassing Compton amplitude, utilizing the operator product expansion. This overcomes issues of renormalization and operator mixing, which so far have hindered lattice calculations of power corrections and higher moments.

Esta institución fue conformada en la ciudad de Buenos Aires, en 1943, por un grupo de mujeres de sectores sociales altos y medios. En un contexto de incertidumbre biomédica la entidad movilizó recursos materiales y simbólicos para dar respuesta al problema de la rehabilitación de las afecciones físicas permanentes que la enfermedad provocaba en sus víctimas. Utilizando como fuente las memorias institucionales de la organización, se muestra cómo médicos y filántropas constituyeron una alianza médico-social y desarrollaron el interés fundamental de practicar una modalidad de tratamiento –en un contexto donde todo estaba por hacerse- sostenidos en un andamiaje que amalgamaba ideas cristianas con innovaciones de la medicina y la rehabilitación.

    Full Text Available This paper presents the technological process of manufacture of a shoe for women in IL system in order to establish the time and the production norm in the processing-sewing procedure. The sequence of operations is presented in a case study that analyzed how can be obtained the upper assembly of a footwear product that later becomes integral part into the finished product. Drawing up the technological process is done considering both the manual operations and the manual-mechanical operations for processing and assembling the parts that make the whole upper assembly by gluing the parts, by seaming and securing the joints. The type of equipment chosen to carry out operations is influencing through its productivity the necessary material calculated and hence the labour force required. The amount of time consists of time needed for preparation-finishing time, operative time, time of working place service and time of regulated interruptions. These periods of times were determined basically by timing assistance of the manufacturing process throughout its development. Production norm is calculated on the basis of the standard time, taking into account that it represents the amount of products manufactured in a work shift In order to improve the process by reducing the time of production and the number of workers engaged we are considering the automation of the manufacturing process by using modern methods using laser cutting or cutting under running water, automatic sewing machines, strip conveyor belts with pace imposed etc.

    Full Text Available War creates a huge need for labour to support the war efforts of the belligerent parties. In South Africa tens of thousands of ‘non-white’ workers were mobilised during the Second World War to satisfy the Union Defence Force’s (UDF’s labour needs at home and abroad. This article, firstly, outlines the role of ‘non-white people’, particularly black Africans, in the UDF with special reference to those employed within the Union of South Africa. Secondly, it briefly delineates typhoid fever as an historical thorn in the flesh of military forces up to the early 20th century. It then looks briefly into the incidence of and perceptions on typhoid fever as a killer disease in South Africa on the eve of the Second World War. Against that background, the article investigates the employment of black workers on the construction of the Berg River-Saldanha Bay military water pipeline and the UDF’s response to the threat and subsequent outbreak of typhoid fever amongst the workers at the Berg River intake site in 1943. The article concludes that the public health authorities and UDF were aware of the threat of typhoid fever with regard to the Berg River water scheme, but did not take sufficient precautionary measures, which could have had serious repercussions for the Allied war effort. This incident should serve as a warning to the South African National Defence Force when deploying on peace support operations on the African continent where typhoid fever remains a serious threat next to Hiv/Aids.

    W H Andrews qualified as a veterinarian in London in 1908 and was recruited soon after, in 1909, by Sir Arnold Theiler to join the staff of the newly established veterinary laboratory at Onderstepoort. After initial studies on the treatment of trypanosomosis and on snake venoms he was deployed by Theiler in 1911 to start research on lamsiekte (botulism)at a field station on the farm Kaffraria near Christiana, where he met and married his wife Doris. After a stint as Captain in the SA Veterinary Corps during World War I he succeeded D T Mitchell as head of the Allerton Laboratory in 1918, where he excelled in research on toxic plants, inter alia identifying Matricaria nigellaefolia as the cause of staggers in cattle. When the Faculty of Veterinary Science was established in 1920 he was appointed as the first Professor of Physiology. After the graduation of the first class in 1924, and due to health problems, he returned to the UK, first to the Royal Veterinary College and then to the Weybridge Veterinary Laboratories of which he became Director in 1927. After his retirement in 1947 he returned to South Africa as a guest worker at Onderstepoort where he again became involved in teaching physiology when Prof. Quin unexpectedly died in 1950. Andrews died in Pretoria in 1953 and was buried in the Rebecca Street Cemetery.

    The Kuroshio Current (KC), one of the most important western boundary currents in the North Pacific Ocean, strongly impacts regional climate in East Asia and upper-ocean thermal structure. However, the responses of KC to regional and remote climate forcing are poorly understood owing to lacking of long-term KC observations. Here, we present a sea surface temperature (SST) record from 1953 to 2004 AD derived from monthly skeletal δ18O data of a living coral Porites core, drilled in Nanwan, southern Taiwan (22°N, 121°E), located on the western front of the Upstream KC. The increased/reduced Kuroshio transport would generate stronger/weaker upwelling in Southern Taiwan, which can cause lower/higher SST. Agreement between dynamics of interannual coral δ18O and modern KC data shows that the regional coral δ18O can be used as a promising proxy for Upstream KC intensity. The KC-induced SST anomaly record reveals prominent interannual and decadal variability predominantly controlled by the bifurcation latitude of North Equatorial Current. We also find that the reconstructed KC intensity at east of Taiwan and south of Japan have nearly simultaneous interannual changes, suggesting the same dominant forcing(s) for the entire KC system. Additional work is needed to understand the KC system with respect to the interannual to decadal climate variability and the influences of global warming.

    As it is well known, the production of Mo-99/Tc-99m generators has an outstanding place in radioisotope programs of the Argentine National Atomic Energy Commission. The basic raw material is Mo-99 from fission of U-235. In 1985 the production plant of this radionuclide began to operate, according to an adaptation of the method that was developed in Kernforschungszentrum Karlsruhe. The present work describes the target irradiation conditions in the reactor RA-3 (mini plates of U/Al alloy with 90% enriched uranium), the flow diagram and the operative conditions of the production process. The containment, filtration and removal conditions of the generated fission gases and the disposal of liquid and solid wastes are also analyzed. On the basis of the experience achieved in the development of more than twenty production processes, process efficiency is analyzed, taking into account the theoretical evaluation resulting from the application of the computer program 'Origin'(ORML) to the conditions of our case. The purity characteristics of the final product are reported (Zr-95 0,1 ppm; Nb-95 1 ppm; Ru-103 20 ppm; I-131 10 ppm) as well as the chemical characteristics that make it suitable to be used in the production of Mo-99/I c-99m generators.

    Uranium was discovered in Saskatchewan in 1934. The first major mill began operating at Beaverlodge in 1953; two other mills began production in the same area in 1955 and 1957. Waste management measures were limited at the early mills. A new generation of mills was brought into production beginning in 1975 utilizing engineered waste management systems. The paper presents a brief description of the geography and physical environment of northern Saskatchewan, Canada; reviews milling operations and waste managements systems; describes the evolution of waste management systems; and, comments on environmental control measures regulating the industry

    In 1921 Prof. Rudolf Weigl started manufacturing on an industrial scale a typhus vaccine. Until the beginning of World War Two he organised five companies called Weigl Institute. During the Soviet occupation the Lvov plant became the Lvov Sanitary and Bacteriological Institute and after the town was taken over by the German Army on 1st July 1941, Prof. Weigl became a head of research of the Military Typhus Institute. It consisted of four sections for manufacturing the vaccine. All the produce was mainly despatched to the Russian front and only very little reached the civilians. In November and December 1943 the plant was moved to Czestochowa into a main building in Wilsona str. and two four storey others in Jasnogórska str. Its head became a German doctor Mozer (witness test). It is difficult to state numbers the plant employed there being no data left but according to employees still alive there must have been about a hundred lab. staff and two hundred feeders. The plant was divided into "breeding", "preparatory" and "liofilisation" sections. "The breeding" was for feeders and breeding lice. Cages containing about 30,000 lice were fastened to voluntary feeders for each feeding. Next "loaders" covered a so-called key board with 20 insects and infectors introduced and pressurised solution containing live rickets into a louse intestine. After a six or seven day passage, lice ware dried and their intestines prepared to produce liofilizeate all the staff and their families were inoculated. ...

    Full Text Available The Second World War’s ramifications and the landing of the Anglo-Americans in North Africa (Torch brought out the antagonism between the powers of the Axis and the Allies. Apart from the military war, a second war including more horrible and complex elements than weapons had been declared by the different rival camps: the propaganda in the Arabic language initiated at the beginning by Germany and Italy and soon developed by Great Britain too (from 1939. It was an efficient and fearsome weapon to control the spirit of the Arab people’s opinion in general, especially that of the Maghrebians, who were often hostile to the British and French colonial policies in their regions. Certainly, radio programmes were preponderant as they were easily accessible but newspapers and leaflets were also used a lot in this psychological war. The subtleties and the impact of this British propaganda will be the subject of research. This article explains the mechanism, the structures, the aims and finally the impact of British propaganda in the Arabic language in North Africa between September 1939 and May 1943.

    2015-05-01

    This paper focuses on the internal organization and dynamics of the Institute Bento da Rocha Cabral (IRC) in Lisbon, a privately-funded institution devoted to biomedical research, from the particular vantage point of its laboratory of biochemistry; in particular, the process through which the institution turned from medically-related to chemically-related research in the period spanning from 1925 to 1953. The history of the IRC raises interesting questions regarding the social politics of science as it materialized the desire of leading physicians of the Faculty of Medicine of Lisbon to create proper physical facilities for medically-related scientific research. We argue that the process which led to the creation of the IRC coincided with the gradual professional and political ascendance of physicians in Portuguese society initiated in the late nineteenth century, and is closely associated with Portuguese republicanism and the process of Lisbon becoming the scientific capital.

  18. The elimination of waste emissions from oil and gas production operations

    Callaghan, D.

    1991-01-01

    This paper reports on the principal waste streams that have been identified from the production operations of all Shell Exploration and Production (E and P) companies. A phased approach has been identified to meet their target of eliminating over time all emissions, effluents and discharges that have a negative impact on the environment. In the short/medium term changes in operational procedures, together with end of pipe technology will be used to reduce emissions. In the longer term, fundamental changes to the production process will be required to eliminate the problem as far as possible at source, to re-use waste streams within the process and return any remaining unwanted material to the producing reservoir, without additional contamination. Carbon dioxide is currently regarded as a special case and will be reduced by minimizing the amount of energy consumed and/or wasted in the production process

  19. Recycling production designs: the value of coordination and flexibility in aluminum recycling operations

    Science.gov (United States)

    Brommer, Tracey H.

    The growing motivation for aluminum recycling has prompted interest in recycling alternative and more challenging secondary materials. The nature of these alternative secondary materials necessitates the development of an intermediate recycling facility that can reprocess the secondary materials into a liquid product Two downstream aluminum remelters will incorporate the liquid products into their aluminum alloy production schedules. Energy and environmental benefits result from delivering the products as liquid but coordination challenges persist because of the energy cost to maintain the liquid. Further coordination challenges result from the necessity to establish a long term recycling production plan in the presence of long term downstream aluminum remelter production uncertainty and inherent variation in the daily order schedule of the downstream aluminum remelters. In this context a fundamental question arises, considering the metallurgical complexities of dross reprocessing, what is the value of operating a coordinated set of by-product reprocessing plants and remelting cast houses? A methodology is presented to calculate the optimal recycling center production parameters including 1) the number of recycled products, 2) the volume of recycled products, 3) allocation of recycled materials across recycled products, 4) allocation of recycled products across finished alloys, 4) the level of flexibility for the recycling center to operate. The methods implemented include, 1) an optimization model to describe the long term operations of the recycling center, 2) an uncertainty simulation tool, 3) a simulation optimization method, 4) a dynamic simulation tool with four embedded daily production optimization models of varying degrees of flexibility. This methodology is used to quantify the performance of several recycling center production designs of varying levels of coordination and flexibility. This analysis allowed the identification of the optimal recycling

    Mortality is described in a cohort of 18,869 white males who were employed between 1943 and 1947 at a uranium conversion and enrichment plant in Oak Ridge, Tenn. Workers in certain departments (especially chemical workers) were exposed to high average air levels of uranium dust. Based on deaths reported in 1974 by the Social Security Administration (SSA) and using mortality rates for US white males, standardized mortality ratios (SMRs) for various causes in the entire cohort were generally less than 1.00. After correction for unascertained deaths and missing death certificates, the SMR for lung cancer was 1.22 (95% confidence limits, 1.10 and 1.36). SMRs for various causes, including lung cancer, did not tend to be higher in 8,345 workers employed in areas where uranium dust was present or in 4,008 of these 8,345 workers employed for one year or longer at the plant. Other causes of particular interest (i.e., bone cancer, leukemia, diseases of respiratory and genitourinary systems) did not exhibit high SMRs. The suggestive finding of the authors was an increased number of lung cancer deaths in a group of chemical workers hired at greater than or equal to 45 years of age. Continued follow-up of the cohort is necessary for further evaluation of the long-term health effects of exposure to uranium

    Production and recovery of biogas from different substrates of agricultural, urban and industrial issues are at the heart of sustainable development for the production of renewable energy, reducing greenhouse gases and waste treatment. In 2011, in France, about 200 biogas plants were operational. Moreover, about 300 ISDND (nonhazardous waste storage or landfill sites) also produce biogas, about 90 that of them valorize it. Because of regulatory contexts and favorable measures to bolster the economy, the number of sites is growing and anaerobic pathways are diversifying in terms of substrate / treated waste, anaerobic digestion processes and ways of valorization. So it seems appropriate to focus on the health and safety of workers potentially exposed to various hazards during operations of monitoring, maintenance or malfunction of facilities. First, through a literature search and a query of experts, data such as substrate, digestate and biogas composition, information feedback on reported incidents / accidents or accidents at work and illnesses of operators have been sought. Then, critical points concerning the health and safety of operators in these sectors were identified by implementing some steps of HACCP (Hazard Analysis - Critical Control Points). Five sectors (agricultural methanization in farms and in centralized plants - methanization of urban sewage sludge - methanization of household garbage - industrial methanization in sectors like food industry, stationery and chemistry - biogas production from landfill sites) have been studied and led to dedicated syntheses. They summarize the collected information and present an operating diagram indicating the different stages of biogas production and recovery. On this diagram, critical points are identified, assessed according to their importance and are associated with phases of maintenance operation, or malfunction. The results are intended to educate the actors to potential risks and attention they need to

    Terra-MOPITT (the Measurements of Pollution in the Troposphere instrument) near real-time (NRT) carbon monoxide (CO) products have been selected for distribution through NASA's LANCE (the Land, Atmosphere Near Real-Time Capability for EOS). MOPITT version 7 NRT data will be made publicly available within 3 hours from observation. The retrieval process is the same for both MOPITT NRT and operational products, albeit for the former it is constrained to use ancillary data available within the latency time. Among other requirements, LANCE NRT products must be examined for quality assurance (QA) purposes and relative errors between NRT and operational products must be quantified. Here we present an algorithm for automatic MOPITT NRT QA aimed to identify artifacts and separate those from anomalously high but real CO values. The algorithm is based on a comparison to the statistics of MOPITT operational products. We discuss the algorithm's performance when tested by applying it to three MOPITT datasets: a known (and corrected) artifact in version 4 operational data, anomalously high CO values in operational data during the 2015 Indonesia fires, and actual NRT data. Last, we describe results from a quantitative comparison between MOPITT NRT data and their operational counterparts.

    The title of this presentation embraces quite a wide scope, however, focus will be on Mobile Production Systems (MPSs) and in particular on Floating Production, Storage and Offloading Units (FPSOs), for which there is presently a remarkable boost in interest particularly in the North Sea area. Over the last 20 years, pioneered by the Argyll TW 58 in 1975, 11 mobile systems have been/are active in the North Sea, i.e. a growth of one for each second year. In 1994 alone a number of eight mobile production systems were contracted of which seven were FPSOs. This boost is following nine years of successful operation of the Petrojarl 1 and is also clearly linked to the success of the Kerr-McGee's Gryphon A project. The title of this presentation reflects new elements in this business; the upturn in interest for FPSOs introduces new ways of thinking and acting. In this paper, the new elements are divided into the general trends; new commercial elements and new technological elements

    2017-01-01

    This essay examines the ways in which U.S. homophile magazines represented and constructed Asia and the Pacific from 1953 to 1964. Through an analysis of 209 items that referenced Asia and the Pacific in ONE, Mattachine Review, and the Ladder, the essay argues that U.S. homophiles referenced the region in three primary ways: first, to create relationships, allies, and exchanges with people living in the region; second, to highlight the inferiority of the East and superiority of the West; and, third, to reveal the cross-cultural and transhistorical nature of homosexuality. These references were influenced by Orientalism, colonialism, and the Cold War, which framed Asia and the Pacific as both sexually and culturally backward, but also as a potential tourist destination for gay men and lesbian women.

    Upcoming weapon programs require an aggressive increase in Application Specific Integrated Circuit (ASIC) production at Sandia National Laboratories (SNL). SNL has developed unique modeling and optimization tools that have been instrumental in improving ASIC production productivity and efficiency, identifying optimal operational and tactical execution plans under resource constraints, and providing confidence in successful mission execution. With ten products and unprecedented levels of demand, a single set of shared resources, highly variable processes, and the need for external supplier task synchronization, scheduling is an integral part of successful manufacturing. The scheduler uses an iterative multi-objective genetic algorithm and a multi-dimensional performance evaluator. Schedule feasibility is assessed using a discrete event simulation (DES) that incorporates operational uncertainty, variability, and resource availability. The tools provide rapid scenario assessments and responses to variances in the operational environment, and have been used to inform major equipment investments and workforce planning decisions in multiple SNL facilities.

    West Nile virus (WNV) is an emerging infectious disease which is most commonly transmitted to humans through mosquito, and is considered a major public-health problem worldwide. The aim of the current study is to bibliometrically analyze the quantity and quality of publications indexed in Scopus from different countries to reveal the characteristics of global research output regarding WNV. This study is a bibliometric analysis based on the Scopus database. This study focused on identifying WNV publication trends with regard to publication year, publication type, prolific countries, language of publication, as well as, prolific journals, citations, and collaboration patterns. A total of 4729 publications were considered in this study, which were published between 1943 and 2016. The annual quantity of literature published before 2000 followed a low rate of research growth; while the quantity of publications after 2000 were published in a stage of rapid development. The country with the greatest number of publications in WNV research field was the USA with 2304 (48.7%) publications, followed by France with 224 (4.7%) publications, and Canada with 222 (4.7%) publications. Contributions from low- and middle-income countries (LMIC) were considerably small, that is, (n = 519 publications; 11%). All publications related to WNV achieved h-index of 140 and were cited 124,222 times. The median [interquartile range] number of citations per article thus amounts to 9 [2-28]. The USA had the highest h-index of 131. Emerging Infectious Diseases is the most productive journal with 227 articles, followed by Journal of Virology with 162 publications. The result designated that Centers for Disease Control and Prevention was ranked the first in terms of publication output, followed by National Center for Emerging and Zoonotic Infectious Diseases. There is an obvious trend of WNV research after 2000, and countries with high income have more contributions in WNV research field. The

    A Multi-arm Placebo-controlled Study with Glutamic Acid Conducted in Rostock in 1953/1954 Glutamic acid was commonly used in the treatment of intellectually disabled children in the 50s. Koch reported first results of an observation of 140 children treated with glutamic acid in 1952. In this line is the multi-arm placebo-controlled study reported here. The original study protocols were available. 58 children with speech problems who attending a school of special needs received glutamic acid, or vitamin B, or St.-John's-wort. The effect of glutamic acid was in few cases an improvement of attention. On the other hand restlessness and stutter increased. The majority of all reported a weight loss. The treatment with vitamin B showed a positive effect concerning concentration. The treatment with St.-John's wort was stopped caused by headache and vomiting in eight of nine cases. The results of the study reported here are unpublished. The reason may be that until the 60s the effects of glutamic acid in the treatment of intellectually disabled children were in generally overestimated.

    Scientific analysis of energy consumption and its influencing factors is of great importance for energy strategy and policy planning. The energy consumption in China 1953-2006 is estimated by applying the energy ecological footprint (EEF) method, and the fluctuation periods of annual China's per capita EEF (EEF cpc ) growth rate are analyzed with the empirical mode decomposition (EMD) method in this paper. EEF intensity is analyzed to depict energy efficiency in China. The main timescales of the 37 factors that affect the annual growth rate of EEF cpc are also discussed based on EMD and factor analysis methods. Results show three obvious undulation cycles of the annual growth rate of EEF cpc , i.e., 4.6, 14.4 and 34.2 years over the last 53 years. The analysis findings from the common synthesized factors of IMF1, IMF2 and IMF3 timescales of the 37 factors suggest that China's energy policy-makers should attach more importance to stabilizing economic growth, optimizing industrial structure, regulating domestic petroleum exploitation and improving transportation efficiency

    Gas oil is the major fossil fuel consumed around the world. Global gas oil consumption is rising at a steadily fast pace because of its higher combustion efficiency (versus gasoline). The annual increase rate of gas oil consumption in Egypt is 7 % whereas, the world increase rates range from 1.5 % to 2 % . The main sources for producing gas oil in Egypt refiners is the direct production from the atmospheric distillation process units or it may be produced as a side product from vacuum distillation units . Gas oil is produced through hydrocracking process of vacuum distillation side streams and heavy cocked gas oil. Gas oil production yield can be increased through the existing operation process units. Modifications of the current atmospheric and vacuum tower operations will increase gas oil yield rates to 20 % more than the existing production rates. The modification of the operating conditions and adoption of the optimum catalyst of the existing hydrocracking and mild hydro cracking process units improve gas oil production yield. Operating delayed cocker at high temperatures, low pressure and low cycle ratio also support achieving the maximization of gas oil yield

    The purpose of this study was to investigate crucial factors on HACCP system implementation in domestic livestock product plants, and to offer job satisfaction and the career prospect of HACCP system operators. The survey was carried out by selecting 150 HACCP system operators who implemented HACCP system. The respondents claimed that the most important contents in HACCP system operation were to assemble HACCP team (21.8%), and the second was to monitoring (20.0%). Documentation and recording (16.9%) and verification (11.1%) were followed. The respondents answered the major factor in sanitation management was cleaning/washing/disinfection (18.9%) and inspection (18.4%). The results showed that there were significant differences in the prospect of occupation in HACCP system operator by the gender (p HACCP system operator were satisfied with their job (73%) and also showed optimistic prospect of occupation (82%).

    2010-03-01

    An operable batch model of simultaneous saccharification and fermentation (SSF) for ethanol production from cellulose has been developed. The model includes four ordinary differential equations that describe the changes of cellobiose, glucose, yeast, and ethanol concentrations with respect to time. These equations were used to simulate the experimental data of the four main components in the SSF process of ethanol production from microcrystalline cellulose (Avicel PH101). The model parameters at 95% confidence intervals were determined by a MATLAB program based on the batch experimental data of the SSF. Both experimental data and model simulations showed that the cell growth was the rate-controlling step at the initial period in a series of reactions of cellulose to ethanol, and later, the conversion of cellulose to cellobiose controlled the process. The batch model was extended to the continuous and fed-batch operating models. For the continuous operation in the SSF, the ethanol productivities increased with increasing dilution rate, until a maximum value was attained, and rapidly decreased as the dilution rate approached the washout point. The model also predicted a relatively high ethanol mass for the fed-batch operation than the batch operation.

  5. Federal Environmental Regulations Impacting Hydrocarbon Exploration, Drilling, and Production Operations

    1999-04-27

    Waste handling and disposal from hydrocarbon exploration, drilling, and production are regulated by the US Environmental Protection Agency (EPA) through federal and state regulations and/or through implementation of federal regulations. Some wastes generated in these operations are exempt under the Resource Conservation and Recovery Act (RCRA) but are not exempt under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Superfund Amendments and Reauthorization Act (SARA), and other federal environmental laws. Exempt wastes remain exempt only if they are not mixed with hazardous wastes or hazardous substances. Once mixture occurs, the waste must be disposed as a hazardous material in an approved hazardous waste disposal facility. Before the Clean Air Act as amended in 1990, air emissions from production, storage, steam generation, and compression facilities associated with hydrocarbon exploration, drilling, and production industry were not regulated. A critical proposed regulatory change which will significantly effect Class II injection wells for disposal of produced brine and injection for enhanced oil recovery is imminent. Federal regulations affecting hydrocarbon exploration, drilling and production, proposed EPA regulatory changes, and a recent significant US Court of Appeals decision are covered in this report. It appears that this industry will, in the future, fall under more stringent environmental regulations leading to increased costs for operators.

    We study Markovian random products on a large class of ‘m-dimensional’ connected compact metric spaces (including products of closed intervals and trees). We introduce a splitting condition, generalizing the classical one by Dubins and Freedman, and prove that this condition implies the asymptotic stability of the corresponding Markov operator and (exponentially fast) synchronization.

  8. Factors affecting research productivity of production and operations management groups: An empirical study

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available This paper identifies factors that promote research productivity of production and operations management (POM groups of researchers in US business schools. In this study, research productivity of a POM group is defined as the number of articles published per POM professor in a specific period of time. The paper also examines factors that affect research quality, as measured by the number of articles published per POM professor in journals, which have been recognized in the POM literature as an elite set. The results show that three factors increase both the research productivity and the quality of the articles published by professors of a POM group. These factors are (a the presence of a POM research center, (b funding received from external sources for research purposes, and (c better library facilities. Doctoral students do assist in improving research quality and productivity, but they are not the driving force. These results have important implications for establishing policy guidelines for business schools. For example, real-world problems are funded by external sources and have a higher probability of publication. Furthermore, schools could place more emphasis on external funding, as most engineering schools do, since groups receiving external funding are more productive in terms of research.

    2014-07-01

    Full Text Available This work seeks to critically analyze the intellectual conditions that the Rühle couple faced during their 1935-1943 political exile in Mexico, after fleeing German National Socialism. Both of them were renowned thinkers both in the academic and political fields, and both before and after World War I, specially during the so-called Weimar Republic. The paper highlights the personality of Alice Rühel-Gerstel, born in Prague to a Jewish family, for she would become a feminist and writer renowned in her time, but forgotten after Nazi censorship. This subject, as yet unpublished in Mexico, feeds on deep archive research carried out in Germany, the Netherlands, and Mexico.

  11. The elusive concept of 'internal objects' (1934-1943). Its role in the formation of the Klein Group.

    Science.gov (United States)

    Hinshelwood, R D

    1997-10-01

    The author traces a debate about the concept of 'internal objects' that took place between 1937 and 1943 at a time when a group of British analysts was forming around Melanie Klein. The debate is set within a complex of personal, group and organisational dynamics, which the paper makes a start on unravelling. The history of the British Psycho-Analytical Society at this time exemplifies Bion's notion of group schism. The events in the Society's history demonstrate defensive aspects of the interaction between the opposed groups, which support members against various anxieties. These include the stress of the work of analysis, but also in this instance the particular anxieties deriving from the collapse of psychoanalysis in Europe, the state of war of the country as a whole, and the death of Freud shortly after he came to London. This psychoanalytic anxiety/defence model clarifies some aspects of the debate about internal objects, and demonstrates the way in which these various anxieties and defences become organised around a scientific debate in a scientific society.

    Hydrogen (H 2 ) is one of renewable energy sources known for its non-polluting and environmentally friendly nature, as its end combustion product is water (H 2 O). The biological production of H 2 is a less energy intensive alternative where processes can be operated at ambient temperature and pressure. Dark fermentation by bacterial biomass is one of multitude of approaches to produce hydrogen which is known as the cleanest renewable energy and is thus receiving increasing attention worldwide. The present study briefly reviews the biohydrogen production process with special attention on the effects of several environmental and operational factors towards the process. Factors such as organic loading rate, hydraulic retention time, temperature, and pH studied in published reports were compared and their influences are discussed in this work. This review highlights the variations in examined operating ranges for the factors as well as their reported optimum values. Divergent values observed for the environmental/operational factors merit further exploration in this field. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    2017-02-01

    The work represents the results of studying basic interconnected criteria of separate equipment units of the transport network machines fleet, depending on production and mining factors to improve the transport systems management. Justifying the selection of a control system necessitates employing new methodologies and models, augmented with stability and transport flow criteria, accounting for mining work development dynamics on mining sites. A necessary condition is the accounting of technical and operating parameters related to vehicle operation. Modern open pit mining dispatching systems must include such kinds of the information database. An algorithm forming a machine fleet is presented based on multi-variation task solution in connection with defining reasonable operating features of a machine working as a part of a complex. Proposals cited in the work may apply to mining machines (drilling equipment, excavators) and construction equipment (bulldozers, cranes, pile-drivers), city transport and other types of production activities using machine fleet.

  17. Flucht ins »Dritte Reich«. Wie Osteuropäer Schutz im NS-Staat suchten (1943–1945

    Directory of Open Access Journals (Sweden)

    Jan-Hinnerk Antons

    2017-08-01

    Full Text Available From 1943 to 1945, several hundred thousand Eastern Europeans fled westwards with the retreating Wehrmacht for fear of Soviet repressions. The flight of non-Germans into the ›Third Reich‹, however, has not attracted special attention in the historiography of migration and refuge. The second contiguous field of study – historical research on Displaced Persons (DPs – rarely touches the topic either, even though relevant groups of non-Jewish DPs in post-war Germany had come this way. The neglect of this topic may stem from its moral ambiguity, as many of the refugees had collaborated to various extents with the German occupation administrations. This article not only seeks to shed light on the motivations, the conditions and the dimensions of this migration, but also tries to show what guided the Nazi authorities in their dealings with the refugees. To what extent did they base their practical actions on the paradigms of racism, economic and military utilitarianism, and political loyalty? The perspectives and records of the Nazi administrations are contrasted with examples of how the events were interpreted in the memoirs of Ukrainian refugees. * * * Hunderttausende Osteuropäer flohen zwischen 1943 und 1945 mit der zurückweichenden Wehrmacht gen Westen, da sie Repressionen der Sowjetmacht erwarteten. Dieser komplexe Vorgang ist in der Historiographie zu Migration und Flucht bislang wenig berücksichtigt worden. Auch das zweite hier relevante Forschungsfeld, die Geschichtsschreibung über Displaced Persons (DPs, hat vom Phänomen der nicht-deutschen Flucht aus Osteuropa kaum Notiz genommen, obwohl relevante Anteile der nicht-jüdischen DPs eben jene Flucht vollzogen hatten. Die Gründe dafür liegen möglicherweise im Unbehagen über die moralische Ambivalenz. Denn viele der Flüchtenden hatten in unterschiedlichen Formen und Ausmaßen als Unterstützer oder Mittäter des Nationalsozialismus agiert. Der Aufsatz geht nicht nur den Motiven

    Full Text Available This paper presents operability guidelines for seafarers on a product tanker which navigates in the Adriatic Sea during heavy weather. Tanker route starts from the Otranto strait in the south to the island Krk in the north of Adriatic Sea. Heavy weather is caused by south wind called jugo (blowing from E-SE to SS-E, sirocco family. Operability guidelines are given based on an operability criteria platform for presenting ship seakeeping characteristics. Operability criteria considered in this paper are propeller emergence, deck wetness and bow acceleration of a product tanker. Limiting values of mentioned criteria determine sustainable speed. Heavy weather is described by extreme sea state of 7.5 m wave height. Wave spectrum used in this paper is Tabain spectrum which is developed specifically for Adriatic Sea. Seafarer's approach of decisions making in extreme weather is also shown and servers as a guideline for further research of the authors.

    In September 2003 the first LCG-1 service was put into production at most of the large Tier 1 sites and was quickly expanded up to 30 Tier 1 and Tier 2 sites by the end of the year. Several software upgrades were made and the LCG-2 service was put into production in time for the experiment data challenges that began in February 2004 and continued for several months. In particular LCG-2 introduced transparent access to mass storage and managed disk-only storage elements, and a first release of the Grid File Access library. Much valuable experience was gained during the data challenges in all aspects from the functionality and use of the middleware, to the deployment, maintenance, and operation of the services at many sites. Based on this experience a program of work to address the functional and operational issues is being implemented. The goal is to focus on essential areas such as data management and to build by the end of 2004 a basic grid system capable of handling the basic needs of LHC c...

  2. General decoupling procedure for expectation values of four-operator products in electron–phonon quantum kinetics

    International Nuclear Information System (INIS)

    Teeny, Nicolas; Fähnle, Manfred

    2013-01-01

    In the density-matrix formalism of electron–phonon quantum kinetics, the hierarchy of infinitely many coupled equations of motion for the expectation values of products of electron and phonon creation and annihilation operators of arbitrary order is usually terminated on the level of the equations of motion for the expectation values of three-operator products by using decoupling procedures for the four-operator products occurring in these equations. In the literature, decoupling procedures are discussed for special types of electron and phonon states. In the present paper, generalized decoupling procedures are derived for arbitrary electron and phonon states. (paper)

    A fluidized-bed biological denitrification (BDN) system was used to treat high-nitrate wastewater streams from a DOE owned uranium processing plant. A two-column system was used to demonstrate BDN operation on a production scale. In a continuous 200 hour rate determination period, the BDN processed over 1.6 million gallons that contained over 4700 kilograms of nitrate and nitrite nitrogen. The BDN removed an average 97% of the incoming nitrate and nitrite. The BDN effluent was discharged to the FMPC sewage treatment plant where it caused increased levels of TOD, TSS and fecal coliforms in the STP discharge. This indicated the BDN effluent will require treatment prior to discharge to the environment. Preliminary chemical consumption rates and associated costs of operation were determined. Several modifications and additions to the system were identified as necessary for the permanent production facility. 3 refs., 11 figs., 2 tabs

    2004-09-01

    The spreading of knowledge depends on the access to the information and its immediate use. Models are useful to explain specific phenomena. The scientific community accepts some models in Biology after a period of time, once it has evidence to support it. The model of the structure and function of the DNA proposed by Watson & Crick (1953) was not the exception, since a few years later the DNA model was finally accepted. In Costa Rica, DNA function was first mentioned in 1970, in the magazine Biologia Tropical (Tropical Biology Magazine), more than 15 years after its first publication in a scientific journal. An opposite situation occurs with technical innovations. If the efficiency of a new scientific technique is proved in a compelling way, then the acceptance by the community comes swiftly. This was the case of the polymerase chain reaction, or PCR. The first PCR machine in Costa Rica arrived in 1991, only three years after its publication.

    Deep-inelastic scattering, in the laboratory and on the lattice, is most instructive for understanding how the nucleon is built from quarks and gluons. The long-term goal is to compute the associated structure functions from first principles. So far this has been limited to model calculations. In this Letter we propose a new method to compute the structure functions directly from the virtual, all-encompassing Compton amplitude, utilizing the operator product expansion. This overcomes issues of renormalization and operator mixing, which so far have hindered lattice calculations of power corrections and higher moments.

    Full Text Available Initially, the publishing processes in the MASSR and Bessarabia of the interwar period developed completely differently in the aesthetic and ideological scope. Their unification is observed after 1940. In the art of book graphics of the Moldavian Soviet Socialist Republic, the transition to socialist realism was characterized by documentation and the domination of illustration characteristics, accumulation of professional skills, formation of creative manners and the author’s styles of illustrators. Evgheni Merega was among the first graphic artists involved in these processes who cooperated with: Tiraspol State Printing House, the State Publishing House (Chisinau, „Shkoala sovetica” and „Uchpedgiz”. Boris Nesvedov and Valentina Neceaev started in the interwar period. In the period 1940–1953, Leonid Grigoraşenco, Ilia Bogdesco, Boris Şirocorad, Iacob Averbuh, Ioachim Postolachi, Aleksandr Neforosov etc. made a name for themselves in the field of book graphics.

  13. Fermi motion versus co-operative effects in subthreshold pion and energetic gamma production

    International Nuclear Information System (INIS)

    Knoll, J.

    1986-06-01

    Various reaction mechanisms proposed to explain the production of pions at 'sub-threshold' energies and of energetic gammas are examined. They range from the nucleon-nucleon single collision mechanism to a co-operative multi-nucleon process. With a shell model prescription for the initial state energies the single collision picture cannot explain the data. The participation of many nucleons in the pion production process appears to be necessary. We present a statistical model which demands the co-operative action of several of the target and projectile nucleons in the pion production process. The formation of composite fragments alongside with the produced pion is seen to be vital to understand the experimental data within this model. (orig.)

    We report on a high power continuous wave (CW) self-mode-locked Tm:YAP laser pumped by a 792 nm laser diode. Without any additional mode-locking elements in the cavity, stable and self-starting mode-locking operation has been realized. The threshold pump power of the CW self-mode-locked Tm:YAP laser is only 5.4 W. The maximum average output power is as high as 1.65 W at the pump power of 12 W, with the repetition frequency of 468 MHz and the center wavelength of 1943 nm. To the best of our knowledge, this is the first CW self-mode-locked Tm:YAP laser. The experiment results show that the Tm:YAP crystal is a promising gain medium for realizing the high power self-mode-locking operation at 2 µm.

    We show how to implement in-memory execution of the core re- lational algebra operations of projection, selection and cross-product eciently, using discrimination-based joins and lazy products. We introduce the notion of (partitioning) discriminator, which par- titions a list of values according...... to a specied equivalence relation on keys the values are associated with. We show how discriminators can be dened generically, purely functionally, and eciently (worst-case linear time) on top of the array-based basic multiset discrimination algorithm of Cai and Paige (1995). Discriminators provide the basis...... the selection operation to recognize on the y whenever it is applied to a cross-product, in which case it can choose an ecient discrimination-based equijoin implementation. The techniques subsume most of the optimization techniques based on relational algebra equalities, without need for a query preprocessing...

    Full Text Available This research examined if Cressey’s (1953 fraud triangle and the agency theory, jointly, enables investigate corporate fraud occurrence in Brazilian banking institutions. It was formulated  six research hypotheses were segregated in fraud triangle – pressure,  opportunity and rationalization – and measured by variables taken from the agency theory, criminology and empirical papers on corporate fraud. The identification of probability of fraud occurrence was operationalized from multinomial logistic model, applied to data of 44 banking, for the period between January 2001 and December 2012. For element pressure, hypotheses No. 01 was confirmed, since this showed that the lower an institution’s previous performance, the greater probability there is of fraudulent events occurring in the future.  In the element of opportunity, the hypothesis No. 03 was confirmed, which showed that low corporate governance indicators increased the possibility of fraud occurrences.  In rationalization element, the hypothesis No. 08 was confirmed, therefore, the predominance of women in management reduces the probability of fraud.  We thereby conclude that Cressey’s Triangle, when combined with the theory of agency is an appropriate research instrument to use when carrying out an investigation into corporate fraud occurrence in banking institutions.

    Aim: In many countries, the age-specific pattern of cervical cancer incidence is currently bipolar with peaks at for instance 45 and 65 years of age. Consequently, a large proportion of cervical cancer cases are presently diagnosed in women above the screening age. The purpose of the study...... was to determine whether this bipolar pattern in age-specific incidence of cervical cancer reflects underlying biology or can be explained by the fact that the data come from birth cohorts with different screening histories. Methods: Combination of historical data on cervical screening and population-based cancer...... incidence data from Denmark 1943–2013, Finland and Norway 1953–2013, and Sweden 1958–2013. Results: Since the implementation of screening, the incidence of cervical cancer has decreased for each successive birth cohort. All birth cohorts showed a unipolar age-specific pattern. In unscreened women in Denmark...

    SKB hands every year over, on behalf of the power companies, to SKI a cost calculation for spent fuel handling and dismantling of the Swedish nuclear power plants. SKI has tried to investigate the future impact which the growth of money in the Nuclear Waste Fund might give in relation to the change of consumer price index, CPI. The long term yield of the Fund has been related to the change of CPI, as the bigger part of the fund money has been invested in real interest rate bonds, issued by the Swedish state. The cost development has been studied with an index named 'KBS-3-index', which is a basket of weighted factor price indexes based on the SKB programme. Since 1986 and up to 2002, the KBS-3-index has increased about 102%, but CPI only about 70%. If this discrepancy should continue during the whole period when Fund money should be available, the Fund would be insufficient. But the difference between KBS-3-index and CPI might be eliminated due to a future productivity development. At the moment, SKI has no knowledge about future productivity development in the SKB programme. A closer analysis of the productivity and efficiency development in the facilities operated by SKB is therefore applicable. Nearest to study is the productivity at the operation of CLAB, Central Interim Storage Facility for Spent Nuclear Fuel. The work in CLAB is receiving and storing of spent nuclear fuel and core components. The consumption of all production factors can be measured in economical means. Here the total production factors are defined as the sum of the annual operation costs and the sum of annuities for reinvestments during the year. The development of total productivity is increasing slightly, but decreasing in the end. Normal for a new business is that the productivity is rising sharply in the beginning. Here the productivity is slightly decreasing in the beginning, and then rising, decreasing, rising and finally decreasing. The project 'compact storing' was finished in 1992

    Full Text Available Matang Mangrove Forest is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. This research was conducted to measure the time and productivity of forest harvesting operation and also to analyze the cost and revenue of mangrove forest harvesting operation at Matang mangrove forest. This project had been carried out in cooperation with Seri Sepetang Enterprise, one of the harvesting licenses in Kuala Sepetang, Perak. Data collections were taken in every station starting from standing tree until to the Kiln-Drying jetty. The data then calculated by using the formulas of productivity and cost analysis. As the result, the productivity for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are 1.84 tan/hour, 3.82 tan/hour and 4.64 tan/hour respectively. The cost for each operation of 9 tan log volume for felling, bucking and debarking, the manual skidding using wheel-barrow and the water transportation are RM 56.88, RM 10.80 and RM 36.72 respectively. As the revenue, the company paid RM 260 per 9 tan of log for the in-forest operation (felling, manual skidding and loading to the ship and pay RM 80 per 9 tan for the water transportation, and they gained the net profit of RM 192.32 and RM 43.28 respectively. The average of forest harvesting operation is twice operation in a day (equal with 2 x 9-ton volume of log production a day, so they will gain a double profit. In conclusion, the forest harvesting operation is sustainably managed for supplying the raw material of charcoal industries in Matang mangrove forest. Since, they work manually and spend much energy in this forest harvesting operation, so for further study it recommends to conduct the ergonomics evaluation during forest harvesting operation at Matang Mangrove Forest.

    Decades of offshore and inland petroleum drilling and production in the Gulf of Mexico and on the Gulf Coast have provided the much needed energy and chemical feedstocks to the nation, and also have made an impact on the environment in the area. Our study showed deposits of contaminated sediment on the ocean floor around offshore platforms, old reserve pits, and dump sites next to many surface facilities and compressor stations. The substances found on the ocean floor and in dump sites are simple or emulsified mixtures of silt, hydrocarbons, and water. The cleaning of the ocean floor and pits is an economic and technical challenge. Hydrocarbons are from crude oil and chemical additions fro various operational necessities, including additions of biocides, corrosion inhibitors, antifreezes, and coagulants. When the new government regulations lower the allowable maximum total organic carbon level to the 50 ppm range, these hydrocarbons can no longer be ignored by drilling and production operators

A brief review of historiography and historical sources are represented also. The author starts with telling about few theoretical remarks about leisure and holiday as phenomena of people's and societyʼs life. It is stressed that Ukrainian insurgents had small choice of free time. But even in wartime they were able to rest. It is emphasized that underground soldiers most of all enjoy to celebrate religious holidays, which reminded them the charm of childhood and family feasts. Main account of holidays and description of features of rebelʼs celebration are scrutinized too in this article. Certain attention is paid to the studying of patriotic holidays within the nationalist community. The author emphasizes that patriotic holidays in most cases have features of official ceremonies. In conclusion author says that holiday and leisure performed several important functions in the insurgents' life.

The scientific community accepts some models in Biology after a period of time, once it has evidence to support it. The model of the structure and function of the DNA proposed by Watson & Crick (1953 was not the exception, since a few years later the DNA model was finally accepted. In Costa Rica, DNA function was first mentioned in 1970, in the magazine Biología Tropical (Tropical Biology Magazine, more than 15 years after its first publication in a scientific journal. An opposite situation occurs with technical innovations. If the efficiency of a new scientific technique is proved in a compelling way, then the acceptance by the community comes swiftly. This was the case of the polymerase chain reaction, or PCR. The first PCR machine in Costa Rica arrived in 1991, only three years after its publication. Rev. Biol. Trop. 52(3: 417-421.

    An evaluation of 218 occupational diseases, which were reported between 1953 and 1979 and officially recognised as being caused by ionising rays, showed these to be made up chiefly by skin disorders (61%, equally distributed over acute and chronic forms), even though considerable percentage shares were also calculated for haematological ailments (15%) and bronchial carcinomas developed by uranium miners. There was a total of 42 deaths, 32 of which were ascribed to uranium mining and 10 to haematological diseases. In all, the annual rate of occupational diseases attributed to ionising rays shows a tendency to decline, even though the number of individuals exposed to radiation is increasing. The incidence of radiation injuries was calculated to be in the order of 0.01% for persons at risk of occupational radiation exposure. (orig./EDB) [de

    Full Text Available The status and activities of the Russian Orthodox Church in the 1942-1943 is analysed on the material of the North Caucasus and the Kuban. Battle for the Caucasus and the Battle of Stalingrad — the crucial events of the World War II — were accompanied by the fi rst phase of the occupation of a large part of the South of Russia. We study both positive and tragic facets of church life in the occupied territories of the enemy. The process of spontaneous legalization of the clergy and parish communities, the Soviet government outlawed in the preceding period, traced the fate of the Orthodox pastors and churches — returning to serve and die at the hands of the Nazis, open to the service and destroyed by Hitler’s army. The internal problems of religious policy of the German Headquarters and especially its implementation in the region, as well as hierarchical and jurisdictional problems caused by the Renovationist schism, and their perspective in conditions of military everyday are examined.

    The refined topological vertex of Iqbal—Kozçaz—Vafa has been investigated from the viewpoint of the quantum algebra of type W 1+∞ by Awata, Feigin, and Shiraishi. They introduced the trivalent intertwining operator Φ which is normal ordered along with some prefactors. We manage to establish formulas from the infinite operator product of the vertex operators and the generalized ones to restore this prefactor, and obtain an explicit formula for the vertex realization of the topological vertex as well as the refined topological vertex

    We propose a method to simulate the real time evolution of one-dimensional quantum many-body systems at finite temperature by expressing both the density matrices and the observables as matrix product states. This allows the calculation of expectation values and correlation functions as scalar products in operator space. The simulations of density matrices in inverse temperature and the local operators in the Heisenberg picture are independent and result in a grid of expectation values for all intermediate temperatures and times. Simulations can be performed using real arithmetics with only polynomial growth of computational resources in inverse temperature and time for integrable systems. The method is illustrated for the XXZ model and the single impurity Anderson model. (paper)

    Reported are the results of a study of the political economy, management, and costs of the successful Guangxi schistosomiasis eradication programme, spanning 40 years from 1953 to 1992. For this purpose we analysed all government data and memoranda on the policy, management, technical support, finance, and the control strategy of the programme. We also interviewed many local staff involved in the programme over the 40-year period and obtained cost data from annual county-level records on seven major categories of variable costs. Schistosomiasis control in Guangxi began with one of the first examples of community participation and rapid assessment in public health history--the use of pre-franked envelopes to return disease questionnaires and suspect snails from rural areas. This approach quickly and accurately delineated the endemic area. This was Mao Zedong's "mass line", incorporating ideas and knowledge from peasants directly into services run for and by them, here the schistosomiasis control programme. Recognition by China's leaders that schistosomiasis was a great economic burden, steadfast prioritizing of the programme over 40 years, local innovative scientific study, agricultural and environmental focus on eradicating the snail hosts and boosting rural production, and mass community education and support were all key factors in the final success. Local leaders motivated programme staff and everyone involved knew the objectives. The programme was always multisectoral, with policy developed centrally, and strategy and collaboration encouraged and rewarded at the grass-roots. These features explain how a very poor autonomous region such as Guangxi finally eradicated schistosomiasis, spending less than US$ 0.50 per protected citizen per year; it is remarkable that the disease and snails were initially found across a large area of complex environments and modern drugs such as praziquantel were not available for most of the 40-year period.

    Construction work involves significant physical, mental, and temporal task demands. Excessive task demands can have negative consequences for safety, errors and production. This exploratory study investigates the magnitude and sources of task demands on a concrete operation, and examines the effect of the production practices on the workers' task demands. The NASA Task Load Index was used to measure the perceived task demands of two work crews. The operation involved the construction of a cast-in-place concrete building under high schedule pressures. Interviews with each crew member were used to identify the main sources of the perceived demands. Extensive field observations and interviews with the supervisors and crews identified the production practices. The workers perceived different level of task demands depending on their role. The production practices influenced the task demands in two ways: (1) practices related to work organization, task design, resource management, and crew management mitigated the task demands; and (2) other practices related to work planning and crew management increased the crew's ability to cope with and adapt to high task demands. The findings identify production practices that regulate the workers' task demands. The effect of task demands on performance is mitigated by the ability to cope with high demands.

    Significant quantities of woody biomass from the tops of trees and larger woody ‘waste’ pieces that fall outside existing sawlog and pulpwood specifications are left on site post final harvest in Australian radiata Pinus radiata (D. Don) (radiata pine) plantations. Woody biomass is a potential product for pulp making or energy generation. Commercial use of woody biomass from radiata pine plantations would add extra value to the Australian plantation estate through improved resource utilisation, and potentially reduced post-harvesting silvicultural costs. This study investigated the productivity and cost impact of the harvest and extraction to roadside of woody biomass in an integrated harvest operation in a typical Australian two machine (harvester/processor and forwarder), cut-to-length, clearfall operation in a mature, thinned radiata pine plantation. The harvest operation yielded 23 GMt/ha (5% of the total yield) of woody biomass (known as ‘fibreplus’), 443 GMt/ha of sawlogs and 28 GMt/ha of pulpwood. The mean quantity of biomass left on site was 128 GMt/ha, mainly consisting of branches and needles, sufficient to minimise nutrient loss and protect the soil from erosion. Woodchips derived from the fibreplus product were suitable for kraft pulp making, (when blended in small amounts with clean de-barked roundwood woodchips), and for energy generation. The method trialed with the fibreplus product being produced did not impact harvesting and processing productivity and costs, but extraction was 14% less productive. Through analysis of the productivities of each phase and development of a cost model the harvest and extraction of the fibreplus product was estimated to increase total unit costs by ∼4.9%. - Highlights: • Study of the productivity and cost impact of producing a woody biomass product. • We compared two scenarios – harvesting with and without the biomass product. • An additional 23 GMt/ha (5% of the total yield) of woody biomass

    We use the numerical conformal bootstrap in two dimensions to search for finite, closed sub-algebras of the operator product expansion (OPE), without assuming unitarity. We find the minimal models as special cases, as well as additional lines of solutions that can be understood in the Coulomb gas formalism. All the solutions we find that contain the vacuum in the operator algebra are cases where the external operators of the bootstrap equation are degenerate operators, and we argue that this follows analytically from the expressions in http://arxiv.org/abs/1202.4698 for the crossing matrices of Virasoro conformal blocks. Our numerical analysis is a special case of the “Gliozzi” bootstrap method, and provides a simpler setting in which to study technical challenges with the method. In the supplementary material, we provide a Mathematica notebook that automates the calculation of the crossing matrices and OPE coefficients for degenerate operators using the formulae of Dotsenko and Fateev.

    Full Text Available The purpose of these studies is to justify the feasibility of recycling different types of industrial waste instead of conventional expensive raw materials in production of environmentally friendly aerated concrete with required construction and operational properties. The impact of wastes from various industries on the environmental condition of affected areas, as well as the results of their environmental assessment were analyzed to determine whether these wastes could be used in production of high-performance building materials. The assessment of industrial wastes in aerated concrete production suggests that industrial wastes of hazard class IV can be recycled to produce aerated concrete. An environmentally friendly method for large-scale waste recycling, including a two-step environmentally sustainable mechanism, was developed. The basic quality indicators of the modified aerated concrete proved that the environmental safety could be enhanced by strengthening the structure, increasing its uniformity and improving thermal insulation properties. The modified non-autoclaved aerated concrete products with improved physical and operational properties were developed. They have the following properties: density – D700; class of concrete – B3.5; thermal transmittance coefficient – 0.143 W/(m·°C; frost resistance – F75.

The feasibility study demonstrated that fuel cells are capable of eliminating the unwanted by-products of combustion engines. However, the use of fuel cells also reduced the amount of ventilation that mines needed to supply, thereby further reducing energy consumption. This study examined the benefits of replacing diesel engines with fuel cells, and discussed the mitigating qualifiers that may limit ventilation energy savings. Solutions to retaining and maintaining additional ventilation in the event of hydrogen leaks from fuel cell stacks were also investigated. The analyses were conducted on 6 operating mines. Current operating costs were compared with future operating conditions using fuel cell powered production vehicles. Operating costs of the primary ventilation system were established with a mine ventilation simulator. The analysis considered exhaust shaft velocities, heating system air velocities, and levels of silica exposure. Canadian mine design criteria were reviewed. It was concluded that appropriate safeguards are needed along hydrogen distribution lines to lower the impacts of hydrogen leaks. Large financial commitments may also be required to ensure a spark-free environment. 20 refs., 6 tabs., 3 figs

    Near real-time (NRT) ocean color (OC) satellite operation products are generated and distributed in NOAA Okeanos Operational Product System, by using the CWAPS including the Multi-Sensor Level (MSL) 12 and the chlorophyll-a frontal algorithms. Current OC operational products include daily chlorophyll concentration (anomaly), water turbidity, remote sensing reflectance and chlorophyll frontal products from Moderate-resolution Imaging Spectroradiometer (MODIS)/Aqua. The products have been widely applied to USA local and state ecosystem research, ecosystem observations, and fisheries managements for coastal and regional forecasting of ocean water quality, phytoplankton concentrations, and primary production. Users of the products have the National Ocean Service, National Marine Fisheries Service, National Weather Service, and Oceanic and Atmospheric Research. Recently, the OC products are being extended to S-NPP VIIRS to provide global NRT ocean color products to user community suh as National Weatrher Service for application for Global Data Assimilation System and Real-Time Ocean Forecast System. However, there remain some challenges in application of the products due to certain product quality and coverage issues. Recent efforts were made to provide a comprehensive web-based Quality Assurance (QA) tool for monitoring OC products quality in near real time mode, referring to http://www.ospo.noaa.gov/Products/ocean/color_new/color.htm. The new QA monitoring tool includes but not limited to the following advanced features applicable for MODIS/Aqua and NPP/VIIRS OC products: 1) Monitoring product quality in NRT mode; 2) Monitoring the availability and quality of OC products with time; 3) Detecting anomalous OC products due to low valid pixels and other quality issues. As an example, potential application and challenges of the ocean color products to oceanic oil spill detection are investigated. It is thus expected that the Okeanos ocean color operational system in

    Full Text Available This essay deals with the fate of Jewish Displaced Persons in Italy from the liberation of the Camp of Ferramonti di Tarsia, by the Allied Army in 1943, until the establishment of the State of Israel in 1948. It focuses on the creation of a complex network of agencies, organizations and individuals involved in assisting the Jewish DPs in Italy, in the framework of the post-war refugee crisis. The article discusses the approaches and ambitions of the rescuers (military authorities, UN agencies and representatives from the Yishuv and the desires of the Jewish DPs themselves, who played an active role both in the administration of the refugee camps as well as in the political discourse regarding their resettlement in British Palestine. Through an analysis of hitherto unexplored archival sources, it will illustrate the development of new sense of belonging and of a renewed identity among the Jewish DPs.

    2003-01-01

    Between 1953 and 1965, Ogden Lindsley and his associates conducted free-operant research with psychiatric inpatients and normal volunteers at Metropolitan State Hospital in Waltham, Massachusetts. Their project, originally named "Studies in Behavior Therapy," was renamed "Harvard Medical School Behavior Research Laboratory" in 1955. This name change and its implications were significant. The role of the laboratory in the history of the relationship between the experimental analysis of behavior and applied behavior analysis is discussed. A case is made for viewing Lindsley's early work as foundational for the subfield of the experimental analysis of human behavior that formally coalesced in the early 1980s. The laboratory's work is also contextualized with reference to the psychopharmacological revolution of the 1950s. Finally, a four-stage framework for studying the historical and conceptual development of behavior analysis is proposed.

  9. NLO QCD corrections to Higgs pair production including dimension-6 operators

    The role of the Higgs boson has developed from the long-sought particle into a tool for exploring beyond Standard Model (BSM) physics. While the Higgs boson signal strengths are close to the values predicted in the Standard Model (SM), the trilinear Higgs-selfcoupling can still deviate significantly from the SM expectations in some BSM scenarios. The Effective Field Theory (EFT) framework provides a way to describe these deviations in a rather model independent way, by including higher-dimensional operators which modify the Higgs boson couplings and induce novel couplings not present in the SM. The trilinear Higgs-selfcoupling is accessible in Higgs pair production, for which the gluon fusion is the dominant production channel. The next-to-leading (NLO) QCD corrections to this process are important for a proper prediction of the cross section and are known in the limit of heavy top quark masses. In our work, we provide the NLO QCD corrections in the large top quark mass limit to Higgs pair production including dimension-6 operators. The various higher-dimensional contributions are affected differently by the QCD corrections, leading to deviations in the relative NLO QCD corrections of several per-cent, while modifying the cross section by up to an order of magnitude.

    An experimental platform based on scaled-down unit operations combined in a plug-and-play manner enables easy and highly flexible testing of advanced biocatalytic process options such as in situ product removal (ISPR) process strategies. In such a platform, it is possible to compartmentalize different process steps while operating it as a combined system, giving the possibility to test and characterize the performance of novel process concepts and biocatalysts with minimal influence of inhibitory products. Here the capabilities of performing process development by applying scaled-down unit operations are highlighted through a case study investigating the asymmetric synthesis of 1-methyl-3-phenylpropylamine (MPPA) using ω-transaminase, an enzyme in the sub-family of amino transferases (ATAs). An on-line HPLC system was applied to avoid manual sample handling and to semi-automatically characterize ω-transaminases in a scaled-down packed-bed reactor (PBR) module, showing MPPA as a strong inhibitor. To overcome the inhibition, a two-step liquid-liquid extraction (LLE) ISPR concept was tested using scaled-down unit operations combined in a plug-and-play manner. Through the tested ISPR concept, it was possible to continuously feed the main substrate benzylacetone (BA) and extract the main product MPPA throughout the reaction, thereby overcoming the challenges of low substrate solubility and product inhibition. The tested ISPR concept achieved a product concentration of 26.5 g MPPA  · L -1 , a purity up to 70% g MPPA  · g tot -1 and a recovery in the range of 80% mol · mol -1 of MPPA in 20 h, with the possibility to increase the concentration, purity, and recovery further.

    International Nuclear Information System (INIS)

    Gould, S.

    1989-01-01

    Twelve-hour scheduling has been a mainstay of the petrochemical industry, is common in the papermill industry, and is relatively new to the nuclear utility industry. A review of industry experiences, research, and a federal Nuclear Regulatory Commission (NRC) study of the 12-hour shift (NUREG/CR-4248) demonstrate that the advantages outweigh the disadvantages. The primary advantages are greater job satisfaction, fewer errors, and the better communications inherent in two shift turnovers versus three. Several companies that implemented the 12-hour shift found an increase in employee morale, no adverse effect on worker health, and no decline in safety. They experienced greater productivity, fewer operator errors, and better communication

    Conformal techniques are applied to the Yukawa model, as an example of a theory with spinor fields. It is written the partial-wave analysis of the 4-point function of two scalars and two spinors in the channel phi psi → phi psi in terms of spinor tensor representations of the conformal group. Using this conformal expansion, it is diagonalized the Bethe-Salpeter equation, which is reduced to algebraic relations among the partial waves. It is shown that in the γ 5 -invariant model, but not in the general case, it is possible to derive dynamically from the expansions of the 4-point function the vacuum operator product phi psi>

  16. Implications of environmental regulations on refinery product specification, operation and investment

    International Nuclear Information System (INIS)

    Amin, M.M.

    1992-01-01

    During the 1980s, refiners mainly in OECD countries were occupied with improving their refinery configurations for producing high-value light products which would not only satisfy the product demand slate but also meet the increasingly restrictive environmental regulations. In the 1990s refiners will continue to be challenged to improve the world's air quality not only by producing products that minimize emissions of toxic and hazardous hydrocarbons, but also through the refinery operation itself by investment in upgrading the industry and products to cope with the constant flow of new regulations. These investments will not only be limited to consuming centres but will also be extended to cover exporting refineries as well due to competition of acquiring market shares for product exports. The additional cost will be directly related to product quality and site regulations and will vary from one country to the other. This paper deals mainly with the air pollution and the impact of related environmental issues on the refining industry. Environmental regulations for refinery products in the USA and Europe are examined and international regulations for the tanker industry are noted. (author)

    2016-07-01

    The goal of this paper is to develop a pragmatic system of a production throughput forecasting system for an automated test operation in a hard drive manufacturing plant. The accurate forecasting result is necessary for the management team to response to any changes in the production processes and the resources allocations. In this study, we design a production throughput forecasting system in an automated test operation in hard drive manufacturing plant. In the proposed system, consists of three main stages. In the first stage, a mutual information method was adopted for selecting the relevant inputs into the forecasting model. In the second stage, a generalized regression neural network (GRNN) was implemented in the forecasting model development phase. Finally, forecasting accuracy was improved by searching the optimal smoothing parameter which selected from comparisons result among three optimization algorithms: particle swarm optimization (PSO), unrestricted search optimization (USO) and interval halving optimization (IHO). The experimental result shows that (1) the developed production throughput forecasting system using GRNN is able to provide forecasted results close to actual values, and to projected the future trends of production throughput in an automated hard disk drive test operation; (2) An IHO algorithm performed as superiority appropriate optimization method than the other two algorithms. (3) Compared with current forecasting system in manufacturing, the results show that the proposed system’s performance is superior to the current system in prediction accuracy and suitable for real-world application. The production throughput volume is a key performance index of hard disk drive manufacturing systems that need to be forecast. Because of the production throughput forecasting result is useful information for management team to respond to any changing in production processes and resources allocation. However, a practically forecasting system for

    Full Text Available Abstract. Market globalization, competitive product and services, high economic crises are the most critical factors that influence the success of the manufacturing companies in global market. Therefore it is critical to the manufacturing companies to be efficient in production and lean tool may used to achieve that.  The most frequently used is the Total Preventive Maintenance (TPM, even though there are many studies have been conducted in relation to the TPM but there is limited research in investigating the effects of the TPM on operational performance. However, the result of the studies was not consistent, where TPM practice may have positive and negative impact on operational performance. Among the reason is the culture of the organization that influenced the implementation of TPM and operational performance. Due to that this study attempts to investigate the influence of organizational culture on the TPM implementation and operational performance.  Rasch model is used in this study due to its ability in interpreting and analyzing the ability of respondents in performing the difficult items. The online questionnaires were distributed to 63 randomly selected automotive companies located at Northern Region of Malaysia.  Results of the study revealed that the organizational culture has influenced on the successful implementation of TPM and operational performance. Therefore by the implementation of TPM in outstanding organizational culture can improve operational performance.   Keyword: Total Preventive Maintenance (TPM, Lean manufacturing, Operational performance, Organizational culture, Rasch modeldoi:10.12695/ajtm.2013.6.2.2How to cite this article:Mohd Asaad, M.N and Yusoff, R.Z.

    Johnson, W. A.; Thomasen, C. T.

    1985-01-01

    Space Transportation System operations managers are being confronted with a unique set of challenges as a result of increasing flight rates, the demand for flight manifest/production schedule flexibility and an emphasis on continued cost reduction. These challenges have created the need for an integrated production planning system that provides managers with the capability to plan, schedule, status and account for an orderly flow of products and services across a large, multi-discipline organization. With increased visibility into the end-to-end production flow for individual and parallel missions in process, managers can assess the integrated impact of changes, identify and measure the interrelationships of resource, schedule, and technical performance requirements and prioritize productivity enhancements.

    2017-01-01

    This essay focuses on representations of Russia, the Soviet Union, and Eastern Europe in U.S. homophile periodicals from 1953 to 1964. Extending the application of Jasbir Puar's concept of homonationalism to the Cold War period, the essay examines 128 articles and other items that were published in ONE, Mattachine Review, and The Ladder and demonstrates that these periodicals often engaged in homonationalist discourses when constructing the Russian, Soviet, and Eastern European "other." Negative constructions of these regions were sometimes used to affirm the political alignment of the homophile authors with the American nation. At other times, negative constructions were used in comparative assessments that critiqued both the United States and the Soviet and Eastern European regions. In contrast, positive constructions of Russian, Soviet, and Eastern European peoples and cultures were used as evidence that non-heteronormative desires and bodies had legitimate places in many "primitive" cultures and existed across all nations and periods.

    2014-06-01

    In the history of genetics Arend Hagedoorn (1885-1953) is mainly known for the 'Hagedoorn effect', which states that part of the changes in variability that populations undergo over time are due to chance effects. Leaving this contribution aside, Hagedoorn's work has received scarcely any attention from historians. This is mainly due to the fact that Hagedoorn was an expert in animal breeding, a field that historians have only recently begun to explore. His work provides an example of how a prominent geneticist envisaged animal breeding to be reformed by the new science of heredity. Hagedoorn, a pupil of Hugo de Vries, tried to integrate his insights as a Mendelian geneticist and an animal breeding expert in a unified view of heredity, eugenics and evolution. In this paper I aim to elucidate how these fields were connected in Hagedoorn's work. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Droughts induce livestock losses that severely affect Kenyan pastoralists. Recent index insurance schemes have the potential of being a viable tool for insuring pastoralists against drought-related risk. Such schemes require as input a forage scarcity (or drought) index that can be reliably updated in near real-time, and that strongly relates to livestock mortality. Generally, a long record (>25 years) of the index is needed to correctly estimate mortality risk and calculate the related insurance premium. Data from current operational satellites used for large-scale vegetation monitoring span over a maximum of 15 years, a time period that is considered insufficient for accurate premium computation. This study examines how operational NDVI datasets compare to, and could be combined with the non-operational recently constructed 30-year GIMMS AVHRR record (1981-2011) to provide a near-real time drought index with a long term archive for the arid lands of Kenya. We compared six freely available, near-real time NDVI products: five from MODIS and one from SPOT-VEGETATION. Prior to comparison, all datasets were averaged in time for the two vegetative seasons in Kenya, and aggregated spatially at the administrative division level at which the insurance is offered. The feasibility of extending the resulting aggregated drought indices back in time was assessed using jackknifed R2 statistics (leave-one-year-out) for the overlapping period 2002-2011. We found that division-specific models were more effective than a global model for linking the division-level temporal variability of the index between NDVI products. Based on our results, good scope exists for historically extending the aggregated drought index, thus providing a longer operational record for insurance purposes. We showed that this extension may have large effects on the calculated insurance premium. Finally, we discuss several possible improvements to the drought index.

    The paper presents a general concept of a hybrid propulsion system, based on an SI internal combustion engine fueled by methanol dissociation products (MDP). The proposed hybrid propulsion scheme is a series hybrid, which allows the engine to be operated in an on-off mode at constant optimal regime. The engine is fed by gaseous products of methanol dissociation (mainly hydrogen and carbon monoxide) emerging from an on-board catalytic reformer. The general scheme and base operation features of the propulsion system are described. The benefits that may be achieved by combining the well-known idea of on-board methanol dissociation with the hybrid vehicle concept are discussed. The proposed scheme is compared with those of systems operating on gasoline, liquid methanol, hydrogen and also with the multi-regime (not hybrid) engine fed by MDP

In this paper, we show that with a very simple generalization, the procedure can be used to investigate quantum mixed states described by matrix product density operators, such as quantum chains at finite temperatures and 1D subchains in high-dimensional lattices. As an example, we study the global discord in the ground state of a 2D transverse-field Ising lattice, and pay our attention to the scaling behavior of global discord in 1D sub-chains of the lattice. We find that, for any strength of the magnetic field, global discord always shows a linear scaling behavior as the increase of the length of the sub-chains. In addition, global discord and the so-called "discord density" can be used to indicate the quantum phase transition in the model. Furthermore, based upon our numerical results, we make some reliable predictions about the scaling of global discord defined on the n × n sub-squares in the lattice.

    Supervisory control and data acquisition (SCADA) systems covering Wascana Energy`s whole southeast Saskatchewan operating area were implemented in 1994-95. The benefits of this automation were described. Operations practices were reviewed and a brief description of the system was provided. Main features of the system described included data storage/retrieval, data display, alarm group organization, alarm call out monitoring, dynagraph display, and the Microsoft SQL server computer. Automation was found to significantly change the operator`s traditional role and altered operation practices in general. SCADA systems were found to improve operating efficiencies and production performance significantly, when properly implemented and utilized. 6 refs., 3 figs.

    The process and the product of anaerobic digestion are evaluated for different proportions of organic substrates, in microreactors operated at thermophilic and mesophilic temperatures with interest to find alternatives that will generate energy from biomass. Small-scale tests are conducted to ensure the proper functioning of biodigesters and optimize operating conditions. The anaerobic digestion process is characterized in three manure mixing ratios: mix of leftovers (100:0,90:10 and 80:20) and two temperatures of work (35 degrees Celsius and 50 degrees Celsius), using a factorial arrangement with 2 replicates per treatment. The mixture is composed of manure, cow dung and scraps of fresh food (fruits and vegetables) and prepared food. The proportions were diluted to 5% total solids. Bottles are the experimental unit used consisting culture medium bottles of 1 liter with 500 mL of mixture. The test has run for 5 hydraulic retention times (HRT) of twenty days each. At this time the pH was evaluated, the daily production of biogas, biogas composition, total solids, volatile and fixed and the content of volatile fatty acids. The values obtained biogas productivity and CH 4 content have been similar to those reported in the literature and indicate that the systems have been successful [es

    The phosphate ore which is processed by Thermphos International in Vlissingen, Netherlands, to produce element phosphorus contains circa 1 Bq per gram uranium 238. As a result of this production process radionuclides are emitted and slags that contain natural radioisotopes are formed. The slags can be used as a building material for roads and water works. During the production of phosphorus the waste material calcinate is formed as well. Operators, working in the production process of phosphorus and laborers, working in road construction and hydraulic engineering inhale radioisotopes. In two articles attention will be paid to the inhalation doses, how the doses are measured, measures that were taken to reduce and control the doses, and the ALARA-principles. This article is focused on the inhalation doses for operators in the phosphorus production industry [nl

    1992-08-01

    This report documents conditions, data and results of dose calculations for accidental and normal operation releases of tritium and activation products, performed within the NET subtask SEP2.2 ('NET-Benchmark') of the European Fusion Technology Programme. For accidental releases, the computer codes UFOTRI and COSYMA for assessing the radiological consequences, have been applied for both deterministic and probabilistic calculations. The influence on dose estimates of different release times (2 minutes / 1 hour), two release heights (10 m / 150 m), two chemical forms of tritium (HT/HTO), and two different model approaches for the deposition velocity of HTO on soil was investigated. The dose calculations for normal operation effluents were performed using the tritium model of the German regulatory guidelines, parts of the advanced dose assessment model NORMTRI still under development, and the statistical atmospheric dispersion model ISOLA. Accidental and normal operation source terms were defined as follows: 10g (3.7 10 15 Bq) for accidental tritium releases, 10 Ci/day (3.7 10 11 Bq/day) for tritium releases during normal operation and unit releases of 10 9 Bq for accidental releases of activation products and fission products.

    This report presents estimated costs and indice for domestic oil and gas field equipment and production operations for 1990, 1991, 1992, and 1993. The costs of all equipment and serives were those in effect during June of each year. The sums (aggregates) of the costs for representative leases by region, depth, and production rate were averaged and indexed. This provides a general measure of the increased or decreased costs from year to year for lease equipment and operations. These general measures do not capture changes in industry-wide costs exactly because of annual variations in the ratio of oil wells to gas wells. The body of the report contains summary tables, and the appendices contain detailed tables. Price changes for oil and gas, changes in taxes on oil and gas revenues, and environmental factors (costs and lease availability) have significant impact on the number and cost of oil and gas wells drilled. These changes also impact the cost of oil and gas production equipment and operations.

    ASI-CGS is routinely providing geodetic excitation functions from its own estimated EOP values (at present SLR and VLBI; the current use of GPS EOP's is also planned as soon as this product will be fully operational) on the ASI geodetic web site (http://geodaf.mt.asi.it). This product has been generated and monitored (for ASI internal use only) in a long pre-operational phase (more than two years), including validation and testing. The daily geodetic excitation functions are now weekly updated along with the operational ASI SLR and VLBI EOP solutions and compared, whenever possible, with the atmospheric excitation functions available at the IERS SBAAM, under the IB and not-IB assumption, including the "wind" term. The work will present the available estimated geodetic function time series and its comparison with the relevant atmospheric excitation functions, deriving quantitative indicators on the quality of the estimates. The similarities as well as the discrepancies among the atmospheric and geodetic series will be analysed and commented, evaluating in particular the degree of correlation among the two estimated time series and the likelihood of a linear dependence hypothesis.

    Pilot infrastructures are becoming prominent players in the Grid environment. One of the major advantages is represented by the reduced effort required by the user communities (also known as Virtual Organizations or VOs) due to the outsourcing of the Grid interfacing services, i.e. the pilot factory, to Grid experts. One such pilot factory, based on the glideinWMS pilot infrastructure, is being operated by the Open Science Grid at University of California San Diego (UCSD). This pilot factory is serving multiple VOs from several scientific domains. Currently the three major clients are the analysis operations of the HEP experiment CMS, the community VO HCC, which serves mostly math, biology and computer science users, and the structural biology VO NEBioGrid. The UCSD glidein factory allows the served VOs to use Grid resources distributed over 150 sites in North and South America, in Europe, and in Asia. This paper presents the steps taken to create a production quality pilot factory, together with the challenges encountered along the road.

    During its active period (1943-1987) the Hanford Nuclear Reservation shaped the history of US nuclear research. It also constitutes an interesting case study of the interface between physics, biology and the politics of Cold War society. Although supposed to turn the US into a stronger military force during the Cold War, the remarkable biological consequences of the nuclear research carried out in the facility ended up overshadowing its original political purpose. The high-level of radioactive waste harmed thousands of people living in the area, causing relevant environmental disasters which make the site the most contaminated area in the US even today. Nuclear research is uniquely dangerous since radiation can cause severe consequences both in terms of lives injured and environmental damage. I address various ways in which nuclear physics and biology were used - and abused - at the Hanford Site to combine the needs of politics with the needs of a healthy society. This paper further investigates the moral responsibility of science to society and the way in which biological research informed nuclear physics about the deleterious consequences of radiation on environment and on the human body.

    Full Text Available Introduction: After the signing of the alliance among Japan, Germany and Italy’s governments in September 1940, several journals arose in order to spread the Japanese culture among people who knew very little about Italy’s new allied. Some documentaries also had the same function. Methods: The numerous textual and iconographical references concerning the Japanese warriors’ anthropology published in some Italian magazines during the 1940s have been compared, as well as to the few Italian monographs on the same theme and to some documentaries by Istituto Nazionale Luce, government propaganda organ. This subject has also been compared to the first Italian cultural production, concerning Japan, which dated back to the first decades of the 20th century. Moreover different intellectuals’ biographies of those times have been deeply analyzed. Results: Comparing to each other the anthropological references about Japan in the Italian cultural production during the Second World War, we can notice a significant ideological homogeneity. This can be explained through their writers’ common sharing of the militaristic, hierarchical and totalitarian doctrine of the Fascist Regime. The Fascist ideology can be summarized in the Bushido concept, as Inazo Nitobe defined it in 1916. This concept was already known in Italy on the early 20th century, far before Fascism. Discussions and conclusions: We can see how Italian perception of the Japanese anthropology on the early 20th century didn’t change over time and how its features will re-appear in the 40s under the influence of the Italian-Japanese coalition. So, Bushido became the essence of the Japanese military and national identity that Fascist Italy took as example for mass education. Some of these stereotypes will re-appear after the war and until recent times in popular culture and in mass perception of Japanese martial arts.

  6. Factors affecting water balance and percolate production for a landfill in operation.

    2005-02-01

    Percolate production and precipitation data for a full-scale landfill in operation measured over a 13-year period were used to evaluate the impact and importance of the hydrological conditions of landfill sections on the percolate production rates. Both active (open) and closed landfill sections were included in the evaluation. A simple top cover model requiring a minimum of input data was used to simulate the percolate production as a function of precipitation and landfill section hydrology. The results showed that changes over time in the hydrology of individual landfill sections (such as section closure or plantation of trees on top of closed sections) can change total landfill percolate production by more than 100%; thus, percolate production at an active landfill can be very different from percolate production at the same landfill after closure. Furthermore, plantation of willow on top of closed sections can increase the evapotranspiration rate thereby reducing percolate production rates by up to 47% compared to a grass cover. This process, however, depends upon the availability of water in the top layer, and so the evaporation rate will be less than optimal during the summer where soil-water contents in the top cover are low.

    Full Text Available La révolution d’octobre 1917 et la guerre civile qui s’ensuivit en Russie eut comme conséquence l’émigration de millions d’orthodoxes russes vers les pays de l’Europe occidentale et plus particulièrement la France. Persuadés depuis le début du déracinement que leur exile avait un caractère providentiel, les orthodoxes russes de France ont œuvré pour la réalisation d’une synthèse qui permettrait le rapprochement entre les chrétiens d’Orient et d’Occident et aboutirait au dépassement définitif des dilemmes identitaires historiques. Durant la période 1925-1953, la reconnaissance du français comme langue liturgique orthodoxe, la fondation de la première paroisse orthodoxe de langue française, l’acceptation dans l’orthodoxie d’un groupe chrétien français utilisant une ancienne forme liturgique gallicane, la recherche pour la reconstitution dudit « rite des Gaules » et les efforts pour l’organisation ecclésiastique d’une « orthodoxie française » sous l’obédience du patriarcat de Moscou, sont des exemples montrant l’engagement sincère de certains esprits pionniers au sein de l’émigration russe pour la réalisation d’une orthodoxie authentiquement occidentale.

Se reconstruye cómo el uso del discurso "antitotalitario" permitió a la dirigencia del partido no sólo condenar, por su asociación con las experiencias europeas, al régimen nacido de la revolución del '43 y al gobierno peronista, sino también cuestionar, por su cercanía con el peronismo, a los comunistas y a los miembros del ala izquierda del mismo Partido Socialista. El recorrido se cierra hacia comienzos de los años cincuenta, momento en que los intelectuales socialistas producen las más densas caracterizaciones del peronismo como fenómeno "totalitario", y justo antes de que la clave "anti-totalitaria" comience a ser cuestionada por la militancia socialista, en particular la juvenil.This article explores the press and the publications of the leaders of the argentine Socialist Party in an effort to account for one of the principal lines of its ideological message: the one represented by the different uses of the term "totalitarianism". It reconstructs the way in which the "anti-totalitarian" discourse allowed the party leadership not only to condemn the regime originated in the revolution which took place in 1943 and the Peronist government which emerged from it by associating both directly with contemporary European experiences, but also to challenge the Communists and left-wing members of the Socialist Party, because of their proximity to Peronism. This ideological itinerary was all but exhausted by the beginning of the '50s, when socialist intellectuals produced their densest characterizations of Peronism as a "totalitarian" phenomenon and just before the"anti-totalitarian" agenda began to be challenged, by grass-roots socialist militants, and particularly by the youth sector of the

    2009-09-15

    This article demonstrated how wireless communications can help oil and gas producers obtain the most current information on the status of their operations to help optimize operations and protect workers and equipment. Wireless communication can provide benefits at nearly every phase of upstream production. When combined with pressure, temperature, flow, level and other sensing devices, wireless communications provide an effective and economical way to deliver data on well or pipeline operations to site managers; optimize well-production, minimize workovers and prevent blowdowns at the wellhead; track oil and water production; measure differential pressure, line pressure and line temperature; and monitor the motorized choke and control valve position. Wireless technology offers significant savings through improved maintenance efficiency. With wireless systems in remote locations, there are seldom problems in the transmission path. Wireless technology makes it much easier and affordable to manage well operations from a safe distance. By eliminating the need for wires in a fracing operation, wireless can help fracing companies maintain a safe operating distance from their target wells, and move operations from well to well with ease. A wireless communication system for transmitting process data from field sensors to a field processing device consists of radio transmitters, a communications gateway and a user interface. The communications hub receives encrypted messages from the remote devices and transmits them to a flow computer, SCADA system, or Distributed Control System. Data is then transmitted to a central office. 1 fig.

The contributions of the time evolution of several peaks to the global one were obtained. Except for the well-known 11-year and the 1-year variations, peaks at 7.7, 5.5, 2 and 1.7 years are found. Several peaks with periods less than 10 months have appeared in our analysis, while the occurrence of 5.1 months is obtained in all the examined solar cycles with a strong signature in cycle 21. Transitions of these quasi-periodicities are seen in power spectra plots. Some of them can be attributed to the modulation of the cosmic ray intensity by solar activity. Others are sporadic and have been previously attributed to the interplanetary magnetic field. The results obtained support once again the argument regarding the difference in the solar activity between odd and even solar cycles.Key words.

    Krad, Ibrahim; Ibanez, Eduardo; Ela, Erik

    2015-10-19

    The recent increased interest in utilizing variable generation (VG) resources such as wind and solar in power systems has motivated investigations into new operating procedures. Although these resources provide desirable value to a system (e.g., no fuel costs or emissions), interconnecting them provides unique challenges. Their variable, non-controllable nature in particular requires significant attention, because it directly results in increased power system variability and uncertainty. One way to handle this is via new operating reserve schemes. Operating reserves provide upward and downward generation and ramping capacity to counteract uncertainty and variability prior to their realization. For instance, uncertainty and variability in real-time dispatch can be accounted for in the hour-ahead unit commitment. New operating reserve methodologies that specifically account for the increased variability and uncertainty caused by VG are currently being investigated and developed by academia and industry. This paper examines one method inspired by the new operating reserve product being proposed by the California Independent System Operator. The method is based on examining the potential ramping requirements at any given time and enforcing those requirements via a reserve demand curve in the market-clearing optimization as an additional ancillary service product.

    The National Oceanic and Atmospheric Administration (NOAA) National Operational Model Archive and Distribution System (NOMADS) provides both real-time and archived atmospheric model output from servers at the National Centers for Environmental Prediction (NCEP) and National Climatic Data Center (NCDC) respectively (http://nomads.ncep.noaa.gov/txt_descriptions/marRutledge-1.pdf). The NOAA National Ocean Data Center (NODC) with NCEP is developing a complementary capability called OceanNOMADS for operational ocean prediction models. An NCEP ftp server currently provides real-time ocean forecast output (http://www.opc.ncep.noaa.gov/newNCOM/NCOM_currents.shtml) with retrospective access through NODC. A joint effort between the Northern Gulf Institute (NGI; a NOAA Cooperative Institute) and the NOAA National Coastal Data Development Center (NCDDC; a division of NODC) created the developmental version of the retrospective OceanNOMADS capability (http://www.northerngulfinstitute.org/edac/ocean_nomads.php) under the NGI Ecosystem Data Assembly Center (EDAC) project (http://www.northerngulfinstitute.org/edac/). Complementary funding support for the developmental OceanNOMADS from U.S. Integrated Ocean Observing System (IOOS) through the Southeastern University Research Association (SURA) Model Testbed (http://testbed.sura.org/) this past year provided NODC the analogue that facilitated the creation of an NCDDC production version of OceanNOMADS (http://www.ncddc.noaa.gov/ocean-nomads/). Access tool development and storage of initial archival data sets occur on the NGI/NCDDC developmental servers with transition to NODC/NCCDC production servers as the model archives mature and operational space and distribution capability grow. Navy operational global ocean forecast subsets for U.S waters comprise the initial ocean prediction fields resident on the NCDDC production server.

    Full Text Available Ethanol is one of renewable energy, which considered being an excellent alternative clean-burning fuel to replaced gasoline. In fact, the application of ethanol as fuel still blended with gasoline. The advantages of using ethanol as fuel are that the raw material mostly from renewable resources and the product has low emission which means environmental friendly. Ethanol can be produced by fermentation of sugars (glucose/fructose. The constraint in the ethanol fermentation batch or continuous process is the ethanol product inhibition. Inhibition in ethanol productivity and cell growth can be overcome by taking the product continuously from the fermentor. The process can be done by using a vacuum fermentation. The objective of this research is to investigate the effect of pressure and glucose concentration in ethanol fermentation. The research was conducted in laboratory scale and batch process. Equipment consists of fermentor with vacuum system. The observed responses were dried cells of yeast, concentration of glucose, and concentration of ethanol. Observations were made every 4 hours during a day of experiment. The results show that the formation of ethanol has a growth-associated product characteristic under vacuum operation. Vacuum condition can increase the cell formation productivity and the ethanol formation, as it is compared with fermentation under atmospheric condition. The maximum cells productivity and ethanol formation in batch operation under vacuum condition was reached at 166.6 mmHg of pressure. The maximum numbers of cells and ethanol formation was reached at 141.2 mm Hg of pressure. High initial glucose concentration significantly can affect the productivity and the yield of ethanol.

In his address President Eisenhower also proposed the establishment of an international atomic The International Atomic Energy Agency became an institutional reality in 1957, when the first General Conference met with 56 members. It now has 83 members, and a further five nations will become members as soon as statutory formalities are completed. The activity on the part of the Agency during these six years has gradually expanded, although it has fallen short of earlier hopes in certain areas. Time and patience, however, have been required and 1963 foreshadows further progress. Ten years after the proposal of the idea, scientists and statesmen can look back and be gratified that a contribution has been made to international understanding. Scientists and statesmen can look ahead, hopefully, to a future of increasing activity in this special agency to develop co-operation and agreement in the field of atomic energy agency which would help channel into peaceful pursuits the scientific and material resources which had been created primarily for military purposes, and noted that such an agency could serve as a vehicle to advance the use of the atom for the peaceful pursuits of mankind. The International Atomic Energy Agency has assumed an essential and natural role in the international development of atomic energy. In

    Artificial Intelligence (AI) is discussed. A number of the computer technologies pioneered in the AI world can make significant contributions to increasing STS operations productivity. Application of expert systems, natural language, speech recognition, and other key technologies can reduce manpower while raising productivity. Many aspects of STS support lend themselves to this type of automation. The artificial intelligence section of the mission planning and analysis division has developed a number of functioning prototype systems which demonstrate the potential gains of applying AI technology.

    Enterobacter asburiae SNU-1 harvested after cultivation was used as a whole cell biocatalyst, for the production of hydrogen. Formic acid was efficiently converted to hydrogen using the harvested cells with an initial hydrogen production rate and total hydrogen production of 491 ml/l/h and 6668 ml/l, respectively, when 1 g/l of whole cell enzyme was used. Moreover, new pH-stat fed-batch operation was conducted, and total hydrogen production was 1.4 times higher than that of batch operation. For practical application, bio-hydrogen produced from formic acid using harvested cells was directly applied to PEMFC for power generation.

  20. Calculation of the Fission Product Release for the HTR-10 based on its Operation History

    Since the first criticality of the HTR-10 test reactor in 2000, a rather complex operation history was performed. As the HTR-10 is the only pebble bed reactor in operation today delivering experimental data for HTR simulation codes, an attempt was made to simulate the whole reactor operation up to the presence. Special emphasis was put on the fission product release behaviour as it is an important safety aspect of such a reactor. The operation history has to be simulated with respect to the neutronics, fluid mechanics and depletion to get a detailed knowledge about the time-dependent nuclide inventory. In this paper we report about such a simulation with VSOP 99/11 and our new fission product release code STACY. While STACY (Source Term Analysis Code System) so far was able to calculate the fission product release rates in case of an equilibrium core and during transients, it now can also be applied to running-in-phases. This coupling demonstrates a first step towards an HCP Prototype. Based on the published power histogram of the HTR-10 and additional information about the fuel loading and shuffling, a coupled neutronics, fluid dynamics and depletion calculation was performed. Special emphasis was put on the complex fuel-shuffling scheme within both VSOP and STACY. The simulations have shown that the HTR-10 up to now generated about 2580 MWd while reshuffling the core about 2.3 times. Within this paper, STACY results for the equilibrium core will be compared with FRESCO-II results being published by INET. Compared to these release rates, which are based on a few user defined life histories, in this new approach the fission product release rates of Ag-110m, Cs-137, Sr-90 and I-131 have been simulated for about 4000 tracer pebbles with STACY. For the calculation of the HTR-10 operation history time-dependent release rates are being presented as well. (author)

    The development of skill assessment software packages and dedicated web applications is a relatively novel theme in operational oceanography. Within the CMEMS IBI-MFC, the quality of IBI (Iberia-Biscay-Ireland) forecast products is assessed by means of NARVAL (North Atlantic Regional VALidation) web-based tool. The validation of IBI against independent in situ and remote-sensing measurements is routinely conducted to evaluate model's veracity and prognostic capabilities. Noticeable efforts are in progress to define meaningful skill scores and statistical metrics to quantitatively assess the quality and reliability of the IBI model solution. Likewise, the IBI-MFC compares the IBI forecast products with other model solutions by setting up specific intercomparison exercises on overlapping areas at diverse timescales. In this context, NARVAL web tool already includes a specific module to evaluate strengths and weaknesses of IBI versus other CMEMS operational ocean forecasting systems (OOFSs). In particular, the IBI physical ocean solution is compared against the CMEMS MED and NWS OOFSs. These CMEMS regional services delivered for the Mediterranean and the North West Shelves include data assimilation schemes in their respective operational chains and generate analogous ocean forecast products to the IBI ones. A number of physical parameters (i.e. sea surface temperature, salinity and current velocities) are evaluated through NARVAL on a daily basis in the overlapping areas existing between these three regional systems. NARVAL is currently being updated in order to extend this intercomparison of ocean model parameters to the biogeochemical solutions provided by the aforementioned OOFSs. More specifically, the simulated chlorophyll concentration is evaluated over several subregions of particular concern by using as benchmark the CMEMS satellite-derived observational products. In addition to this IBI comparison against other regional CMEMS products on overlapping areas, a

    Growing switchgrass (Panicum virgatum L.) as an intercrop in managed loblolly pine (Pinus taeda L.) plantations has emerged as a potential source of bioenergy feedstock. Utilizing land resources between pine trees to produce an energy crop can potentially reduce the demand for land resources used to produce food; however, converting conventionally managed forest land to this new intercropping system constitutes changes in land use and associated management practices, which may affect the environmental and economic sustainability of the land.

    The overall objective of this project is to evaluate the environmental effects of large-scale forest bioenergy crop production and utilize these results to optimize cropping systems in a manner that protects the important ecosystem services provided by forests while contributing to the development of a sustainable and economically-viable biomass industry in the southeastern United States.

    Specific objectives are to:

    1. Quantify the hydrology of different energy crop production systems in watershed scale experiments on different landscapes in the southeast.
    2. Quantify the nutrient dynamics of energy crop production systems in watershed scale experiments to determine the impact of these systems on water quality.
    3. Evaluate the impacts of energy crop production on soil structure, fertility, and organic matter.
    4. Evaluate the response of flora and fauna populations and habitat quality to energy crop production systems.
    5. Develop watershed and regional scale models to evaluate the environmental sustainability and productivity of energy crop and woody biomass operations.
    6. Quantify the production systems in terms of bioenergy crop yield versus the energy and economic costs of production.
    7. Develop and evaluate best management practice guidelines to ensure the environmental sustainability of energy crop production systems.

    Full Text Available Conventional production measurement of truck dispatching system in open pit mine has not been effectively expressed by a mathematical model, which brings a negative effect on the subsequent data mining and a compatibility issue to apply the production measurement with fixed assignment of truck. In this study, based on the proposed concept that truck is not only the carrier of transport material, but also act as the bridges and linkages between the loading sites and the unloading sites, a new truck operation diagram was established, which was further developed to a basic data matrix and a production measurement model. The new model allowed to calculatethe production measurement of the transport, loading, unloading, material and etc, respectively, as well as with any calculation in combination of more than one factor as needed.It solved the compatibility issue between conventional production measurement and the production measurement of fixed assignment of truck with good practical results.

    Data were collected from 1953 through 1980 from identical and fraternal twin beef and dairy females born in 1953, 1954, 1959, 1964, and 1969, and from crossbred females born as singles in 1974, and their progeny. Numbers of dams that weaned at least 1 calf and were included in the first analysis were 37, 45, and 56 in the 1964, 1969, and 1974 data sets, respectively. Respective numbers of dams that weaned 3 calves and were included in a second analysis were 6, 8, 8, 22, 33, and 33 in the 1953, 1954, 1959, 1964, 1969, and 1974 experiments. Individual feed consumption was measured at 28-d intervals from the time females were placed on the experiment until 3 calves were weaned or the dams had reached 5 yr of age. Residual feed intake (RFI) and residual gain (RG) of the heifers that subsequently became the dams in this study were determined based on ADG and DMI from 240 d of age to first calving. Various measures of cow efficiency were calculated on either a life cycle or actual lifetime basis using ratios of progeny and dam weight outputs to progeny and dam feed inputs. Residual feed intake was phenotypically independent of ADG and metabolic midweight (MMW), whereas the correlation between RFI and DMI was positive and highly significant ( = 0.67; calving had superior efficiency ratios as cows. Residual feed intake was not significantly correlated with age at puberty, age at calving, or milk production. Results of this study do not indicate any serious antagonisms of postweaning heifer RFI with subsequent cow and progeny performance traits or with life cycle or actual lifetime cow efficiency. In addition, selection for increased RG would result in earlier ages at calving, but would also tend to result in taller and heavier cows.

  6. Energy momentum tensor and operator product expansion in local causal perturbation theory

    International Nuclear Information System (INIS)

    2000-09-01

    We derive new examples for algebraic relations of interacting fields in local perturbative quantum field theory. The fundamental building blocks in this approach are time ordered products of free (composed) fields. We give explicit formulas for the construction of Poincare covariant ones, which were already known to exist through cohomological arguments. For a large class of theories the canonical energy momentum tensor is shown to be conserved. Classical theories without dimensionful couplings admit an improved tensor that is additionally traceless. On the example of φ 4 -theory we discuss the improved tensor in the quantum theory. Its trace receives an anomalous contribution due to its conservation. Moreover, we define an interacting bilocal normal product for scalar theories. This leads to an operator product expansion of two time ordered fields. (orig.) [de

    1994-09-01

    The 185-D deaeration building and the 189-D refrigeration building were constructed at Hanford during 1943 and 1944. Both buildings were constructed as part of the influent water cooling system for D reactor. The CMS studies eliminated the need for 185-D function. Early gains in knowledge ended the original function of the 189-D building mission. In 1951, 185-D and 189-D were converted to a thermal-hydraulic laboratory. The experiments held in the thermal-hydraulic lab lead to historic changes in Hanford reactor operations. In late 1951, the exponential physics experiments were moved to the 189-D building. In 1958, new production reactor experiments were begun in 185/189-D. In 1959, Plutonium Recycle Test Reactor experiments were added to the 185/189-D facility. By 1960, the 185/189-D thermal hydraulics laboratory was one of the few full service facilities of its type in the nation. During the years 1961--1963 tests continued in the facility in support of existing reactors, new production reactors, and the Plutonium Recycle Test Reactor. In 1969, Fast Flux Test Facility developmental testings began in the facility. Simulations in 185/189-D building aided in the N Reactor repairs in the 1980's. In 1994 the facility was nominated to the National Register of Historic Places, because of its pioneering role over many years in thermal hydraulics, flow studies, heat transfer, and other reactor coolant support work. During 1994 and 1995 it was demolished in the largest decontamination and decommissioning project thus far in Hanford Site history

En la primera parte del texto se aborda el período de la Guerra Civil, en el que, ante la insólita avalancha de detenciones de mujeres practicadas por los alzados, por primera vez en la historia de las Baleares fue preciso improvisar un centro de reclusión femenino. A continuación, se estudian los cambios operados en 1940 a raíz de la reconversión del modesto penal palmesano en una de las prisiones centrales de mujeres de España. En el tercer apartado, se trata de la singular presencia en esta cárcel de la congregación de Hermanas de la Caridad y su incidencia en la vida cotidiana. Seguidamente, se explican los mecanismos y estrategias de resistencia practicadas por las penadas para mejorar sus condiciones de vida, protegerse frente a las medidas disciplinarias adoptadas por las autoridades penitenciarias y difundir su ideario político. Finalmente, se alude brevemente a las causas y consecuencias de la clausura del centro penitenciario mallorquín y al proceso de recuperación de la memoria de las antiguas encarceladas desarrollado en la última década.

    2014-04-10

    The effect of increasing organic loading rate (OLR) and simultaneously decreasing hydraulic retention time (HRT) during anaerobic digestion of sulphur- and nitrogen-rich thin stillage was investigated during operation of continuously stirred tank laboratory reactors at two different temperatures. The operating strategies and substrate were set in order to mimic an existing full-scale commercial biogas plant in Sweden. The reactors were operated for 554-570 days with a substrate mixture of thin stillage and milled grain, resulting in high ammonium concentrations (>4.5gL(-1)). Initially, one reactor was operated at 38°C, as in the full-scale plant, while in the experimental reactor the temperature was raised to 44°C. Both reactors were then subjected to increasing OLR (from 3.2 to 6.0gVSL(-1)d(-1)) and simultaneously decreasing HRT (from 45 to 24 days) to evaluate the effects of these operational strategies on process stability, hydrogen sulphide levels and microbial composition. The results showed that operation at 44°C was the most successful strategy, resulting in up to 22% higher methane yield compared with the mesophilic reactor, despite higher free ammonia concentration. Furthermore, kinetic studies revealed higher biogas production rate at 44°C compared with 38°C, while the level of hydrogen sulphide was not affected. Quantitative PCR analysis of the microbiological population showed that methanogenic archaea and syntrophic acetate-oxidising bacteria had responded to the new process temperature while sulphate-reducing bacteria were only marginally affected by the temperature-change.

    The analysis in this document serves the purpose of defining a number of attributes in selection of feed items to be utilized in recovery/recycle of Pu and also production operations of 241AmO2 material intended to meet specification requirements. This document was written in response to a specific request on the part of the 2014 annual program review which took place over the dates of October 28-29, 2014. A number of feed attributes are noted including: (1) Non-interference with existing Pu recovery operations; (2) Content of sufficient 241Am to allow process efficiency in recovery operations; (3) Absence of indications that 243Am might be mixed in with the Pu/241Am material; (4) Absence of indications that Cm might be mixed in with the Pu/241Am material; (5) Absence of indications of other chemical elements that would present difficulty in chemical separation from 241Am; (6) Feed material not expected to present difficulty in dissolution; (7) Dose issues; (8) Process efficiency; (9) Size; (10) Hazard associated with items and package configuration in the vault; (11) Within existing NEPA documentation. The analysis in this document provides a baseline of attributes considered for feed materials, but does not presume to replace the need for technical expertise and judgment on the part of individuals responsible for selecting the material feed to be processed. This document is not comprehensive as regards all attributes that could prove to be important. The value of placing a formal QA hold point on accepting feed items versus more informal management of feed items is discussed in the summation of this analysis. The existing planned QA hold points on 241AmO2 products produced and packaged may be adequate as the entire project is based on QA of the product rather than QA of the process. The probability of introduction of items that would inherently cause the241

    We have carried out experiments using a ''sweep gas'' technique to determine the behaviour of short-lived fission products within operating, intact UO 2 fuel elements. The Zircaloy-4-clad elements were 500 mm long and contained fuel of density 10.65-10.71 Mg/m 3 . A He-2% H 2 carrier gas swept gaseous or volatile fission products out of the operating fuel element past a gamma spectrometer for measurement. In tests at linear powers of 45 and 60 kW/m to maximum burnups of 70 MW.h/kg U, the species measured directly at the spectrometer were generally the short-lived xenons and kryptons. We did not observe iodine or bromine during normal operation. However, we have deduced the behaviour of I-133 and I-135 from the decay of Xe-133 and Xe-135 during reactor shutdowns. Plots of R/B (released/born) against lambda (decay constant) or effective lambda for all isotopes observed at 45 and 60 kW/m show that a line of slope -0.5, corresponding with diffusion kinetics, is a good fit to the measured xenon and krypton data. Our inferred release of iodine fits the same line. From this we can extrapolate to an R/B for I-131 of about 5x10 -3 . The ANS 5.4 release correlation gives calculated results in good agreement with our measurements. (author)

    Production strategies definition, applied to petroleum fields, must consider physical, operational and economic constraints. It is common to consider only the reservoir conditions on the optimization processes, simplifying, many times, the process by not taking into account the operational constraints due to production facilities. There are two main reasons: considering the operational constraints makes the process much complex and it is assumed that this simplification can affect the economic indicators but dos not affect significantly the optimization process (number e location of wells, for example). The capacity of a production unit can be limited by many constrains such as: maximum liquid rate, capacity of water and gas treatment, gas compression, water or gas injection, number of wells, etc. In this work, we show that these limitations have a direct influence in the oil production and consequently in the economic indicators and they can cause significant impact at production strategy definition, influencing the number of production and injection wells, their locations and their operational conditions. We presented an example of an offshore field with a limitation on the liquid rate. Production strategies were selected with and without constraints in order to observe the differences in the technical and economic indicators, such as NPV (Net Present Value), production and injection of fluids and the number and location of the production and injection wells. It was possible to observe yet that the amount and location of the wells were significantly affected by the restriction. (author)

    The decision to study the nuclear energy in France in 1945 has seen the construction of the first natural uranium reactor for research purpose only, Zoe reactor. The utilization of heavy water as moderator was motivated by permitting the economical utilization of natural uranium oxides as fuel and a good handling. The five tons of heavy water required by the Zoe reactor were initially obtained from Norway production. With nuclear development and the construction of the first power reactors for electricity production, the demand in heavy water increased. The heavy water production by French industry became of a great interest. The first production started in the southwest of France using a fertilizers production plant and the electrolytic process used in Norway. The electrolytic process of hydrogen was quickly limited by the limited number of large fertilizers plants in France. Thus, in 1953, French nuclear research concentrated on the distillation of liquid hydrogen and water distillation for the heavy water production. The liquid hydrogen distillation presents a better yield in heavy water extraction than the electrolytic process but it was still depending from large fertilizers production plants. Although the water distillation process is simple, the high purity required for nuclear uses induced a high cost. The advantages and disadvantages of these two processes are discussed as well as others heavy water production processes using concentration process of already enriched water and the prospect of the use of the natural gas from the Lacq deposit. Economical aspect and cost production for each of heavy water production processes will be also discussed. (M.P.)

    2016-01-01

    Professor Bolesław Jałowy (1906-1943) was a chairman of Department of Histology and Embryology at Faculty of Medicine of King John Casimir University (Polish: Universytet Jana Kazimierza: UJK) in Lvov. He succeeded Professor Władysław Szymonowicz (1869-1939) who held this position for decades. As the most skillful followers of his tutor, Bolesław Jałowy was a great investigator of physiology of human tissue, embryogenesis, histological consequences of female sex hormones on blood clotting action as well as regeneration of nerves in addition to description of silver staining technique for reticulin fibers of skin. He was a hard working person with gentle attitude to such a subtle matter as microscopic structure of human body. However, he happened to live in brutal conditions of nationalistic struggles. His example shows how much a dedicated scientist could do in a very short time as his life was tragically ended with murdering him during World War Two. His story is a great lesson for generations of academic workers how to meet high moral standards with efficient and creative scientific work in evil and destructive, nationalistic climate that occurs usually in wartime.

  3. Approach for planning and operation of energy-efficient production systems; Vorgehensweise fuer Planung und Betrieb energieeffizienter Produktionssysteme

    2010-07-02

    The integration of energy efficiency criteria into planning and operating of production systems substantially contributes to resource productivity and thus is an essential prerequisite for global sustainable development. Great potential can be identified for an early consideration of energy efficiency measures in an early planning phase. It is necessary to determine energy requirements during the planning process before the system is implemented. The objective of this thesis is the development of a planning system for the detailed prognosis of a production system's energy consumption. A concept is derived, by which a time based prediction of the amount of energy required by each machine and thus by the whole production system becomes possible. The planning system is methodologically integrated with well established approaches for manufacturing and factory planning. The methodology is based on the separation of production processes into segments, each with specific energy consumption. These segments, which are defined for equipment according to the possible operational states, are called EnergyBlocks. Each EnergyBlock describes the energy consumed and has a fixed or variable duration. A fixed duration results from operational states which last the shortest time technically possible, for example a machine start process. Variable durations represent operational states, whose length are dependant of the production task. Examples are manufacturing processes. The energy consumption of one block is mathematically described using power series. The energy consumption profile of a planned, not yet realized production process is modeled by arranging the EnergyBlocks to sequences. Depending on when the developed planning system is applied in the process of manufacturing and factory planning, energy consumption prognosis can be calculated as a power profile or as total consumption values, using the same model for both cases. Thus, the information density can be chosen

    The present work establishes intermittent operation of UASB reactors as a novel form of enhancing the anaerobic degradation of complex wastewaters and its conversion to usable biogas. Results show that the average methane production rate is 25% higher with the intermittent operation than with the continuous mode, meaning that it could produce 25% more electricity or heat. The methanization efficiency obtained in intermittent UASB reactors is around 20% higher than in the continuous systems, confirming a higher biological degradation of the substrates. It has been suggested that intermittent operation causes a forced adaptation of the biomass towards the degradation of complex substrates and results from morphological analyses of the biomass developed in intermittent and continuous UASB reactors showed marked differences between them. In order to gain a deeper knowledge on how microbial populations are affected by these operational parameters, a strategy involving the amplification, cloning, and analysis of the nucleotide sequences of genes encoding the 16S ribosomal RNA was undertaken and is described in this work. This strategy allowed the identification of a total of 49 different sequences. Results from the molecular characterization of the microbial populations are consistent with the higher methanization efficiency of the intermittent mode of operation.

    In this study, the effects of the type and concentration of nitrogen sources on the cell growth and lutein content of an isolated microalga Scenedesmus obliquus FSP-3 were investigated. With batch culture, the highest lutein content (4.61 mg/g) and lutein productivity (4.35 mg/L/day) were obtained when using 8.0 mM calcium nitrate as the nitrogen source. With this best nitrogen source condition, the microalgae cultivation was performed using two bioreactor strategies (namely, semi-continuous and two-stage operations) to further enhance the lutein content and productivity. Using semi-continuous operation with a 10% medium replacement ratio could obtain the highest biomass productivity (1304.8 mg/L/day) and lutein productivity (6.01 mg/L/day). This performance is better than most related studies. Copyright © 2014 Elsevier Ltd. All rights reserved.

    1994-01-01

    Department of Energy (DOE), United States Geological Survey (USGS), and Idaho Chemical Processing Plant (ICPP) documents were searched for information regarding service disposal operations, and the chemical characteristics and volumes of the service waste emplaced in, and above, the Eastern Snake River Plain aquifer (ESRP) from 1953-1992. A summary database has been developed which synthesizes available, but dispersed, information. This assembled data records spatial, volumetric and chemical input patterns which will help establish the initial contaminant water characteristics required in computer modeling, aid in interpreting the monitoring well network hydrochemical information, and contribute to a better understanding of contaminant transport in the aquifer near the ICPP. Gaps and uncertainties in the input record are also identified with respect to time and type. 39 refs., 5 figs., 5 tabs

    Phenological data from a variety of platforms - across a range of spatial and temporal scales - are required to support research, natural resource management, and policy- and decision-making in a changing world. Observational and modeled phenological data, especially when integrated with associated biophysical data (e.g., climate, land-use/land-cover, hydrology) has great potential to provide multi-faceted information critical to decision support systems, vulnerability and risk assessments, change detection applications, and early-warning and forecasting systems for natural and modified ecosystems. The USA National Phenology Network (USA-NPN; www.usanpn.org) is a national-scale science and monitoring initiative focused on understanding the drivers and feedback effects of phenological variation in changing environments. The Network maintains a centralized database of over 10M ground-based observations of plants and animals for 1954-present, and leverages these data to produce operational data products for use by a variety of audiences, including researchers and resource managers. This presentation highlights our operational data products, including the tools, maps, and services that facilitate discovery, accessibility and usability of integrated phenological information. We describe (1) the data download tool, a customizable GUI that provides geospatially referenced raw, bounded or summarized organismal and climatological data and associated metadata (including calendars, time-series curves, and XY graphs), (2) the visualization tool, which provides opportunities to explore, visualize and export or download both organismal and modeled (gridded) products at daily time-steps and relatively fine spatial resolutions ( 2.5 km to 4 km) for the period 1980 to 6 days into the future, and (3) web services that enable custom query and download of map, feature and cover services in a variety of standard formats. These operational products facilitate scaling of integrated

    1996-12-01

    Several patient-, procedure-, and prescriber-related factors are thought to influence the decision to administer allogeneic blood products. We reexamine a number of assertions applied commonly to the practice of transfusion in cardiac operations. More than 50 original articles including a total of more than 10,000 patients from 70 centers were reviewed. Data from 5,426 patients operated on between 1990 and 1994 at the Montreal Heart Institute are presented. From our review of the literature, we conclude that postoperative mediastinal fluid drainage averages 917 mL and that aspirin therapy increases drainage by less than 300 mL in most studies, which should not increase use of blood products, insofar as a strict transfusional protocol is adhered to. Across centers, transfusions can vary eightfold for the same postoperative drainage. Data from our institution show that postoperative mediastinal drainage per se is not influenced by reoperation or by the type of operation. However, total blood losses and transfusion requirements remain increased in reoperative and complex procedures. Excessive mediastinal drainage resulting in increased transfusions occurs in 29% of patients. Exposure to allogeneic transfusions remains institution dependent. Constant reevaluation of local practice is essential to implement efficient blood conservation strategies.

  13. Costs and indices for domestic oil and gas field equipment and production operations 1994 through 1997

    International Nuclear Information System (INIS)

    1998-03-01

    This report presents estimated costs and cost indices for domestic oil and natural gas field equipment and production operations for 1994, 1995, 1996, and 1997. The costs of all equipment and services are those in effect during June of each year. The sums (aggregates) of the costs for representative leases by region, depth, and production rate were averaged and indexed. This provides a general measure of the increased or decreased costs from year to year for lease equipment and operations. These general measures do not capture changes in industry-wide costs exactly because of annual variations in the ratio of the total number of oil wells to the total number of gas wells. The detail provided in this report is unavailable elsewhere. The body of this report contains summary tables, and the appendices contain detailed tables. Price changes for oil and gas, changes in taxes on oil and gas revenues, and environmental factors (compliance costs and lease availability) have a significant impact on the number and cost of oil and gas wells drilled. These changes also impact the cost of oil and gas equipment and production operations

    Kim, H; Choi, J-S; Lee, S

    2012-01-01

    Pressure retarded osmosis (PRO) is a novel membrane process to produce energy. PRO has the potential to convert the osmotic pressure difference between fresh water (i.e. river water) and seawater to electricity. Moreover, it can recover energy from highly concentrated brine in seawater desalination. Nevertheless, relatively little research has been undertaken for fundamental understanding of the PRO process. In this study, the characteristics of the PRO process were examined using a proof-of-concept device. Forward osmosis (FO), reverse osmosis (RO), and nanofiltration (NF) membranes were compared in terms of flux rate and concentration polarization ratio. The results indicated that the theoretical energy production by PRO depends on the membrane type as well as operating conditions (i.e. back pressure). The FO membrane had the highest energy efficiency while the NF membrane had the lowest efficiency. However, the energy production rate was low due to high internal concentration polarization (ICP) in the PRO membrane. This finding suggests that the control of the ICP is essential for practical application of PRO for energy production.

    This research analyses the productivity of energy wood chipping operations at several sites in Austria and Finland. The aim of the work is to examine the differences in productivity and the effects of the operational environment for the chipping of bioenergy at the roadside. Furthermore, the study quantifies the effects of different variables such as forest energy assortments, tree species, sieve size and machines on the overall productivity of chipping. The results revealed that there are significant differences in the chipping productivity in Austria and Finland which are largely based on the use of different sieve sizes. Furthermore, the different operational environments in both countries, as well as the characteristics of the raw material also seem to have an effect on productivity. In order to improve the chipping productivity, particularly in Central European conditions, all relevant stakeholders need to work jointly to find solutions that will allow a greater variation of chip size. Furthermore, in the future more consideration has to be given to the close interlinkage between the chipper, crane and grapple. As a result, investments costs can be optimized and operational costs and stress on the machines reduced. (orig.)

    Shevchenko, V.I.; Simonov, Yu.A.

    2004-01-01

    We analyze the structure of current-current correlators in coordinate space in the large N c limit when the corresponding spectral density takes the form of an infinite sum over hadron poles. The latter are computed in the QCD string model with quarks at the ends, including the lowest states, for all channels. The corresponding correlators demonstrate reasonable qualitative agreement with the lattice data without any additional fits. Different issues concerning the structure of the short-distance operator product expansion are discussed

    1981-01-01

    Radappertization is particularly applicable to precooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been designated as the leading agency for the US Federal food and nutrition programmes

    α-Hexachlorocyclohexane (HCH), β-HCH, and lindane (γ-HCH) were listed as persistent organic pollutants by the Stockholm Convention in 2009 and hence must be phased out and their wastes/stockpiles eliminated. At the last operating lindane manufacturing unit, we conducted a preliminary evaluation of HCH contamination levels in soil and water samples collected around the production area and the vicinity of a major dumpsite to inform the design of processes for an appropriate implementation of the Convention. Soil and water samples on and around the production site and a major waste dumpsite were measured for HCH levels. All soil samples taken at the lindane production facility and dumpsite and in their vicinity were contaminated with an isomer pattern characteristic of HCH production waste. At the dumpsite surface samples contained up to 450 g kg(-1) Σ HCH suggesting that the waste HCH isomers were simply dumped at this location. Ground water in the vicinity and river water was found to be contaminated with 0.2 to 0.4 mg l(-1) of HCH waste isomers. The total quantity of deposited HCH wastes from the lindane production unit was estimated at between 36,000 and 54,000 t. The contamination levels in ground and river water suggest significant run-off from the dumped HCH wastes and contamination of drinking water resources. The extent of dumping urgently needs to be assessed regarding the risks to human and ecosystem health. A plan for securing the waste isomers needs to be developed and implemented together with a plan for their final elimination. As part of the assessment, any polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) generated during HCH recycling operations need to be monitored.

    2011-01-01

    The Operator Product Expansion (OPE) of current correlators at short distances beyond perturbation theory in QCD, together with Cauchy's theorem in the complex energy plane, are the pillars of the method of QCD sum rules. This technique provides an analytic tool to relate QCD with hadronic physics at low and intermediate energies. It has been in use for over thirty years to determine hadronic parameters, form factors, and QCD parameters such as the quark masses, and the running strong coupling at the scale of the τ-lepton. QCD sum rules provide a powerful complement to numerical simulations of QCD on the lattice. In this talk a short review of the method is presented for non experts, followed by three examples of recent applications.

    Full Text Available Ethanol is one of renewable energy, which considered being an excellent alternativeclean-burning fuel to replaced gasoline. In fact, the application of ethanol as fuel still blended withgasoline. The advantages of using ethanol as fuel are that the raw material mostly from renewableresources and the product has low emission which means environmental friendly. Ethanol can beproduced by fermentation of sugars (glucose/fructose. The constraint in the ethanol fermentationbatch or continuous process is the ethanol product inhibition. Inhibition in ethanol productivityand cell growth can be overcome by taking the product continuously from the fermentor. Theprocess can be done by using a vacuum fermentation. The objective of this research is toinvestigate the effect of pressure and glucose concentration in ethanol fermentation. The researchwas conducted in laboratory scale and batch process. Equipment consists of fermentor withvacuum system. The observed responses were dried cells of yeast, concentration of glucose, andconcentration of ethanol. Observations were made every 4 hours during a day of experiment. Theresults show that the formation of ethanol has a growth-associated product characteristic undervacuum operation. Vacuum condition can increase the cell formation productivity and the ethanolformation, as it is compared with fermentation under atmospheric condition. The maximum cellsproductivity and ethanol formation in batch operation under vacuum condition was reached at166.6 mmHg of pressure. The maximum numbers of cells and ethanol formation was reached at141.2 mm Hg of pressure. High initial glucose concentration significantly can affect the productivityand the yield of ethanol.

    Klein, Marty; Rilling, Mark

    1972-01-01

    Two experiments investigated free-operant avoidance responding with pigeons using a treadle-pressing response. In Experiment I, pigeons were initially trained on a free-operant avoidance schedule with a response-shock interval of 32 sec and a shock-shock interval of 10 sec, and were subsequently exposed to 10 values of the response-shock parameter ranging from 2.5 to 150 sec. The functions relating response rate to response-shock interval were similar to the ones reported by Sidman in his 1953 studies employing rats, and were independent of the order of presentation of the response-shock values. Shock rates decreased as response-shock duration increased. In Experiment II, a free-operant avoidance schedule with a response-shock interval of 20 sec and a shock-shock interval of 5 sec was used, and shock intensities were varied over five values ranging from 2 to 32 mA. Response rates increased markedly as shock intensity increased from 2 to 8 mA, but rates changed little with further increases in shock intensity. Shock rates decreased as intensity increased from 2 to 8 mA, and showed little change as intensity increased from 8 to 32 mA. PMID:4652617

    The most common method for assessment of a photovoltaic (PV) system performance is by comparing its energy production to reference data (irradiance or neighboring PV system). Ideally, at normal operation, the compared sets of data tend to show a linear relationship. Deviations from this linearity

    The design of a nuclear installation associated with chemical processes depends fundamentally on the risks derived from the materials and process used. The operative experience brings useful data mainly related to the ventilation and equipment design that allow to improve the handling of operational incidents and maintenance work. The paper presents the results extracted from a production campaign; ambient and personal monitoring results from monitorings performed routinely and during special interventions are commented.

    This study proposes a method to develop efficient operational policies for a reservoir the southern Chile. The main water uses in this system are hydropower and irrigation, with conflicting seasonal demands. The conflict between these two uses is currently managed through a so-called "irrigation agreement" which defines a series of operational conditions on the reservoir by restricting volumes used for power production depending on reservoir storage level. Other than that, the reservoir operation is driven by cost-minimization over the power grid. Recent evidence shows an increasing degree of conflict in this basin, which suggests that the static approach of irrigation agreements, might no longer be appropriate. Moreover, this agreement could be revised in light of decreased water availability. This problem poses a challenge related to the spatial scope of analysis. Thus, irrigation benefits are driven by decisions made within the basin, whereas hydropower benefits depend on the operation of the entire power grid. Exploring the tradeoffs between these two water uses involves modeling both scales. The proposed methodology integrates information from both a grid-wide power operations model and a basin-wide agro-economic model into a decision model for optimal reservoir operation. The first model, a hydrothermal coordination tool, schedules power production by each plant in the grid, and allows capturing technical and economic aspects to the operation of hydropower reservoirs. The agro-economic model incorporates economic features of irrigation in the basin, and allows obtaining irrigation water demand functions. Finally, the results of both models are integrated into a single model for optimal reservoir operation considering the tradeoffs between the two uses. The result of the joint operation of water resources, show a flexible coordination of uses, revealing the opportunity cost of irrigation, which it gives the possibility of negotiating transfers of water to

    SUMMARY Research was undertaken to clarify the true taxonomic position of the terrestrial tortoise apicomplexan, Haemogregarina fitzsimonsi (Dias, 1953). Thin blood films were screened from 275 wild and captive South African tortoises of 6 genera and 10 species between 2009-2011. Apicomplexan parasites within films were identified, with a focus on H. fitzsimonsi. Ticks from wild tortoises, especially Amblyomma sylvaticum and Amblyomma marmoreum were also screened, and sporogonic stages were identified on dissection of adult ticks of both species taken from H. fitzsimonsi infected and apparently non-infected tortoises. Parasite DNA was extracted from fixed, Giemsa-stained tortoise blood films and from both fresh and fixed ticks, and PCR was undertaken with two primer sets, HEMO1/HEMO2, and HepF300/HepR900, to amplify parasite 18S rDNA. Results indicated that apicomplexan DNA extracted from tortoise blood films and both species of tick had been amplified by one or both primer sets. Haemogregarina  fitzsimonsi 18S rDNA sequences from tortoise blood aligned with those of species of Hepatozoon, rather than those of species of Haemogregarina or Hemolivia. It is recommended therefore that this haemogregarine be re-assigned to the genus Hepatozoon, making Hepatozoon fitzsimonsi (Dias, 1953) the only Hepatozoon known currently from any terrestrial chelonian. Ticks are its likely vectors.

    The impact of power plant operation on the abundance and productivity of phytoplankton was monitored over a period of fifteen months. Field studies showed that in spite of the consistent reduction in phytoplankton biomass and productivity at the Outfall where the heated effluent is discharged, stations close to the mixing point did not show any significant change in phytoplankton biomass or productivity. This suggested that at the Mixing point, mixing of the heated effluents with the ambient seawater was rapid and very extensive, ensuring recovery of phytoplankton biomass and their productivity potential. Field studies during low-dose, shock-dose and no-chlorination suggested that chlorination caused greater damage to phytoplankton chlorophyll than temperature. Laboratory experiments revealed that diatom growth was not much influenced by passage through the condenser cooling system and they were able to grow between 28 deg C and 40 deg C. Short term experiments indicated that chemical stress due to chlorination might be more important than temperature in reducing phytoplankton biomass and productivity. Combined treatment of temperature and chlorine showed little synergistic effect. The data suggest that formulation of condenser discharge criteria of power plants must consider the relative effects of both the stress factors viz., temperature and chlorine. (author)

    This study examines the joint and separate influence of birth weight and body mass in young adulthood on subsequent coronary heart disease (CHD) risk. A cohort of 9,143 men born in Copenhagen, Denmark, in 1953, for whom information on birth weight and body weight and height around age 19 years were...... retrieved from birth certificates and conscript records, respectively, were followed from 1978 until 2005 (between age 25 and 52 years) for incident fatal and non-fatal CHD. Data on CHD were obtained through record linkage to the Cause of Death Registry and the National Patient Registry. During follow......-up, a total of 475 men had a CHD diagnosis. Men with low birth weight, high body mass index (BMI) at age 19, a father from the working class, and low educational level at age 19 had an increased risk for CHD. Birth weight was inversely associated with CHD only in men with BMI of 25 kg/m(2) or above...

    Two uncommon, morphologically similar snapping shrimps, Alpheus percyi Coutière, 1908 and A. pseudopugnax (Banner, 1953), are reported from various localities across the Indo-West and Central Pacific. Both species are re-diagnosed based on type specimens and recently collected material; a lectotype is designated for A. percyi. The range of A. pseudopugnax, previously known only from the type locality in Hawaii, is extended considerably to French Polynesia and Reunion Island in the western Indian Ocean. Both A. percyi and A. pseudopugnax present a significant variation in the post-rostral region of the carapace, making identification of specimens based solely on morphology rather difficult. In the field, however, the two species can be easily separated by their diagnostic and very striking colour patterns. Colour patterns also suggest that A. percyi may be more closely related to the species of the A. gracilipes Stimpson, 1860 complex than to A. pseudopugnax.

    Marine sponges usually constitute the most diverse group of the benthic community in coral reefs. Although they are reasonably well studied at the northern Gulf of Mexico (GMx), the southern GMx is poorly known and lacks records from many major reef systems that lie off the Mexican coast. The present taxonomic study is the first sponge account from Alacranes reef, the largest coral reef system in the GMx, and from the shallow reef banks of Sisal, both in the northwest Yucatan Peninsula. The 19 species herein described represent the first sponge fauna records from these reefs. Among these, seven species represent new record for GMx: Erylus formosus, Cliona flavifodina, Spirastrella aff. mollis, Strongylacidon bermuda, Topsentia bahamensis, Agelas tubulata and Chelonaplysilla aff. erecta. Twelve species are new records for the Southern GMx: Erylus trisphaerus, Cliona amplicavata, Chondrilla caribensis, Halichondria lutea, Hymeniacidon caerulea, Axinella corrugata, Dragmacidon reticulatum, Chalinula molitba, Amphimedon caribica, A. complanata, Hyatella cavernosa and Dysidea variabilis. Additionally, a redescription of Erylus trisphaerus is presented which had not been reviewed since its original description in 1953 off Western Florida, except that it was listed for north La Habana, Cuba.

    Full Text Available In June 1943 took place a coup d’etat in Argentina that initiated a process of confrontation between an important sector of academic scientists and the de facto military government. As a result, many scientists lost their positions at universities, between them a group of biomedical scientists led by the physiologist Bernardo Houssay, who was to be awarded the Nobel Prize in Physiology in 1947. From that moment on, supported by local philanthropists and the Rockefeller Foundation, Houssay’s group began to promote the creation of a series of private research institutes. This process continued during the democratic government of Juan Perón (1946-1955. This article analyzes this “project” —its motivations and objectives— as a process of “parallel” institutionalization which was divergent from the initiatives promoted for science and technology by the public sector. This “splitting” of the institutionalization process, embodied in ideologies, institutional models and hardly compatible epistemic hierarchies, would have far-reaching consequences for the future development of research in Argentina.En junio de 1943 se produjo en la Argentina un golpe de Estado que inició un proceso de enfrentamientos entre un importante sector de científicos académicos y el gobierno militar de facto.

    This paper refers to testing procedures of the production capacity of heavy water production pilot, industrial scale plants and of heavy water reconcentration facilities. Simulation codes taking into account the mass and heat transfers inside the exchange columns were developed. These codes provided valuable insight about the isotope build-up of the installation which allowed estimating the time of reaching the stationary regime. Also transient regimes following perturbations in the operating parameters (i.e. temperature, pressure, fluid rates) of the installation were simulated and an optimal rate of routine inspections and adjustments was thus established

  17. Costs and indices for domestic oil and gas field equipment and production operations, 1992--1995

    International Nuclear Information System (INIS)

    1996-08-01

    This report presents estimated costs and cost indices for domestic oil and natural gas field equipment and production operations for 1992, 1993, 1994, and 1995. The costs of all equipment and services are those in effect during June of each year. The sum (aggregates) of the costs for representative leases by region, depth, and production rate were averaged and indexed. This provides a general measure of the increased or decreased costs from year to year for lease equipment and operations. These general measured do not capture changes in industry-wide costs exactly because of annual variations in the ratio of the total number of oil wells to the total number of gas wells. The detail provided in this report is unavailable elsewhere. The body of this report contains summary tables, and the appendices contain detailed tables

    Background Nuclear transfer (NT) technologies offer a means for producing the genetically modified pigs necessary to develop swine models for mechanistic studies of disease processes as well as to serve as organ donors for xenotransplantation. Most previous studies have used commercial pigs as surrogates. Method and Results In this study, we established a cloning technique for miniature pigs by somatic cell nuclear transfer (SCNT) using Nippon Institute for Biological Science (NIBS) miniature pigs as surrogates. Moreover, utilizing this technique, we have successfully produced an α-1, 3-galactosyltransferase knockout (GalT-KO) miniature swine. Fibroblasts procured from a NIBS miniature pig fetus were injected into 1312 enucleated oocytes. The cloned embryos were transferred to 11 surrogates of which five successfully delivered 13 cloned offspring; the production efficiency was 1.0% (13/1312). In a second experiment, lung fibroblasts obtained from neonatal GalT-KO MGH miniature swine were used as donor cells and 1953 cloned embryos were transferred to 12 surrogates. Six cloned offspring were born from five surrogates, a production efficiency of 0.3% (6/1953). Conclusions These results demonstrate successful establishment of a miniature pig cloning technique by SCNT using NIBS miniature pigs as surrogates. To our knowledge, this is the first demonstration of successful production of GalT-KO miniature swine using miniature swine surrogates. This technique could help to ensure a stable supply of the cloned pigs through the use of miniature pig surrogates and could expand production in countries with limited space or in facilities with special regulations such as specific pathogen-free or good laboratory practice.

    We investigated whether/how cardiac surgeons can be productive both academically and clinically. Using online resources (New York State Adult Cardiac Surgery database, SCOPUS), we collected individual clinical volumes (operations performed/year), academic metrics (ongoing publications, role as author), practice setting, and seniority for all cardiac surgeons in the State of New York from 1994 to 2011. Over time, individual clinical volumes decreased (median operations/year: 193 in 1995 vs 126 in 2010; P published more worked at hospitals with higher clinical volumes (Spearman's correlation coefficient: 0.16; P publishing at all; ∼45 per cent operating less, but publishing a little; ∼15 per cent clinically very productive (operating as much as the nonpublishers) and publishing a lot; and ∼1 per cent operating the least, but publishing the most.

  20. Conformal Haag-Kastler nets, pointlike localized fields and the existence of operator product expansions

    1994-10-01

    Starting from a chiral conformal Haag-Kastler net on 2 dimensional Minkowski space we construct associated pointlike localized fields. This amounts to a proof of the existence of operator product expansions. We derive the result in two ways. One is based on the geometrical identification of the modular structure, the other depends on a ''conformal cluster theorem'' of the conformal two-point-functions in algebraic quantum field theory. The existence of the fields then implies important structural properties of the theory, as PCT-invariance, the Bisognano-Wichmann identification of modular operators, Haag duality and additivity.

    Highlights: • BMP test displayed high gas potential generation capacity of MBT waste. • Strong inhibition effects were observed due to ammonia and VFA accumulation. • Waste water content was found as the key parameter limiting gas generation. • First order k-values were determined for different operating conditions. - Abstract: In this work, the influence of different operating conditions on the biogas production from mechanically–biologically treated (MBT) wastes is investigated. Specifically, different lab-scale anaerobic tests varying the water content (26–43% w/w up to 75% w/w), the temperature (from 20 to 25 °C up to 55 °C) and the amount of inoculum have been performed on waste samples collected from a full-scale Italian MBT plant. For each test, the gas generation yield and, where applicable, the first-order gas generation rates were determined. Nearly all tests were characterised by a quite long lag-phase. This result was mainly ascribed to the inhibition effects resulting from the high concentrations of volatile fatty acids (VFAs) and ammonia detected in the different stages of the experiments. Furthermore, water content was found as one of the key factor limiting the anaerobic biological process. Indeed, the experimental results showed that when the moisture was lower than 32% w/w, the methanogenic microbial activity was completely inhibited. For the higher water content tested (75% w/w), high values of accumulated gas volume (up to 150 Nl/kgTS) and a relatively short time period to deplete the MBT waste gas generation capacity were observed. At these test conditions, the effect of temperature became evident, leading to gas generation rates of 0.007 d{sup −1} at room temperature that increased to 0.03–0.05 d{sup −1} at 37 °C and to 0.04–0.11 d{sup −1} at 55 °C. Overall, the obtained results highlighted that the operative conditions can drastically affect the gas production from MBT wastes. This suggests that particular caution

    The structure of organizations that provide services should reflect the possibilities of and constraints on production that arise from the market segments they serve. Organizational segmentation in health care is based on urgency and severity as well as disease type, bodily function, principal method, or population subgroup. The result is conflicting priorities, goals, and performance metrics. A managerial perspective is needed to identify activities with similar requirements for integration, coordination, and control. The arguments in this article apply new reasoning to the previous literature. The method used in this article to classify health care provision distinguishes different types of health problems that share generic constraints of production. The analysis leads to seven different demand-supply combinations, each with its own operational logic. These are labeled demand and supply-based operating modes (DSO modes), and constitute the managerial building blocks of health care organizations. The modes are Prevention, Emergency, One visit, Project, Elective, Cure, and Care. As analytical categories the DSO modes can be used to understand current problems. Several operating modes in one unit create managerial problems of conflicting priorities, goals, and performance metrics. The DSO modes are constructed as managerially homogeneous categories or care platforms responding to general types of demand, and supply constraints. The DSO modes bring methods of industrial management to bear on efforts to improve health care. © 2010 Milbank Memorial Fund. Published by Wiley Periodicals Inc.

    This report covers the area committed to the Grayburg Cooperative and Unit Agreement (I-Sec. 370) approved by the Assistant Secretary of the Interior on October 5, 1943, hereafter referred to as the "unit area", embracing 4,769.44 acres of public land in T. 17 S., Rs. 29 and 30 E., Eddy County, New Mexico. The area includes portions of the Anderson, Grayburg-Jackson, and Leonard oil fields as defined for proration purposes by the New Mexico Oil Conservation Commission. The unit area is covered by Federal oil and gas leases owned by the Grayburg Oil Company of New Mexico and the Western Production Company, Inc. The Grayburg Unit Association has been formed and designated to conduct and manage all operations in the unit area. As of December 31, 1943, there were forty-six producing oil wells within the unit area. The report has been prepared for the purpose of assisting the Grayburg Unit Association in determining the proper locations of gas-injection wells and the best methods for future operation of the pressure-maintenance system that is being installed for the purpose of retarding the reservoir pressure decline and increasing the ultimate recovery of oil from the Grayburg Zone defined in the above-mentioned agreement as formations not more than 3300 feet below the surface. Data used in the report were obtained from records on file in the Geological Survey office at Roswell, New Mexico, and from the records of the Western Production Company and the Grayburg Oil Company. All data were carefully checked as to accuracy with engineers and field representatives of both companies.

    2010-01-01

    Information about reported encounters of aircraft with volcanic ash clouds from 1953 through 2009 has been compiled to document the nature and scope of risks to aviation from volcanic activity. The information, gleaned from a variety of published and other sources, is presented in database and spreadsheet formats; the compilation will be updated as additional encounters occur and as new data and corrections come to light. The effects observed by flight crews and extent of aircraft damage vary greatly among incidents, and each incident in the compilation is rated according to a severity index. Of the 129 reported incidents, 94 incidents are confirmed ash encounters, with 79 of those having various degrees of airframe or engine damage; 20 are low-severity events that involve suspected ash or gas clouds; and 15 have data that are insufficient to assess severity. Twenty-six of the damaging encounters involved significant to very severe damage to engines and (or) airframes, including nine encounters with engine shutdown during flight. The average annual rate of damaging encounters since 1976, when reporting picked up, has been approximately 2 per year. Most of the damaging encounters occurred within 24 hours of the onset of ash production or at distances less than 1,000 kilometers from the source volcanoes. The compilation covers only events of relatively short duration for which aircraft were checked for damage soon thereafter; documenting instances of long-term repeated exposure to ash (or sulfate aerosols) will require further investigation. Of 38 source volcanoes, 8 have caused 5 or more encounters, of which the majority were damaging: Augustine (United States), Chaiten (Chile), Mount St. Helens (United States), Pacaya (Guatemala), Pinatubo (Philippines), Redoubt (United States), Sakura-jima (Japan), and Soufriere Hills (Montserrat, Lesser Antilles, United Kingdom). Aircraft have been damaged by eruptions ranging from small, recurring episodes to very large

    Key performance indicators (KPIs) are critical for manufacturing operation management and continuous improvement (CI). In modern manufacturing systems, KPIs are defined as a set of metrics to reflect operation performance, such as efficiency, throughput, availability, from productivity, quality and maintenance perspectives. Through continuous monitoring and measurement of KPIs, meaningful quantification and identification of different aspects of operation activities can be obtained, which enable and direct CI efforts. A set of 34 KPIs has been introduced in ISO 22400. However, the KPIs in a manufacturing system are not independent, and they may have intrinsic mutual relationships. The goal of this paper is to introduce a multi-level structure for identification and analysis of KPIs and their intrinsic relationships in production systems. Specifically, through such a hierarchical structure, we define and layer KPIs into levels of basic KPIs, comprehensive KPIs and their supporting metrics, and use it to investigate the relationships and dependencies between KPIs. Such a study can provide a useful tool for manufacturing engineers and managers to measure and utilize KPIs for CI.

    Full Text Available This work evaluates technological and economic transference related to the Production of Penicillin Amidase for use in 6 Amine Penicillanic acid (6-APA Production Project, wich is a part of the United Nations1 Regional Biotechnology Programme for Latin America and the Caribbean. This paper analyses the evolution of international cooperation by looking at the project's development. The methodology used includes analysis of: the project's development; participant and budgetary goals; results; copyright; project conditions; and sale of biocatalyst and 6-APA. All technical objectives were achieved; international co-operation, as well as co-operation between Industry and University were successful. Technological transference to the pilot plant was effective; many students involved in the project were simultaneously taking M.Sc. and Ph.D's courses. Nevertheless, neither the technology necessary for the biocatalyst's manufacture nor the biocatalyst itself were used. Analysis of the project has provided some orientation concerning those internal and external problems which arose during the development and sale of biotechnology in our countries and has tried to propose some alternatives for taking advantage of international co-operation.

    This paper investigates multi-fuel multi-product operation of IGCC plants with carbon capture and storage (CCS). The investigated plant designs co-process coal with different sorts of biomass (e.g. sawdust) and solid wastes, through gasification, leading to different decarbonised energy vectors (power, hydrogen, heat, substitute natural gas etc.) simultaneous with carbon capture. Co-gasification of coal with different renewable energy sources coupled with carbon capture will pave the way towards zero emissions power plants. The energy conversions investigated in the paper were simulated using commercial process flow modelling package (ChemCAD) in order to produce mass and energy balances necessary for the proposed evaluation. As illustrative cases, hydrogen and power co-generation and Fischer–Tropsch fuel synthesis (both with carbon capture), were presented. The case studies investigated in the paper produce a flexible ratio between power and hydrogen (in the range of 400–600 MW net electricity and 0–200 MW th hydrogen considering the lower heating value) with at least 90% carbon capture rate. Special emphasis were given to fuel selection criteria for optimisation of gasification performances (fuel blending), to the selection criteria for gasification reactor in a multi-fuel multi-product operation scenario, modelling and simulation of whole process, to thermal and power integration of processes, flexibility analysis of the energy conversion processes, in-depth techno-economic and environmental assessment etc. - Highlights: • Assessment of IGCC-based energy vectors poly-generation systems with CCS. • Optimisation of gasification performances and CO 2 emissions by fuel blending. • Multi-fuel multi-product operation of gasification plants

    The NESDIS Center for Satellite Applications and Research (STAR), formerly ORA, Office of Research and Applications, consists of three research and applications divisions that encompass satellite meteorology, oceanography, climatology, and cooperative research with academic institutions. With such a wide background of talent, and a charter to develop operational algorithms and applications, STAR scientists develop satellite-derived land, ice, ocean, and atmospheric environmental data products in support of all of NOAA"s mission goals. In addition, in close association with the Joint Center for Satellite Data Assimilation, STAR scientists actively work with the numerical modeling communities of NOAA, NASA, and DOD to support the development of new methods for assimilation of satellite data. In this new era of observations from many new satellite instruments, STAR aims to effectively integrate these data into multi-platform data products for utilization by the forecast and applications communities. Much of our work is conducted in close partnerships with other agencies, academic institutes, and industry. In order to support the nearly 400 current satellite-derived products for various users on a routine basis from our sister operations office, and to evolve to future systems requires an ongoing strategic planning approach that maps research and development activities from NOAA goals to user requirements. Since R&D accomplishments are not necessarily amenable to precise schedules, appropriate motivators and measures of scientific progress must be developed to assure that the product development cycle remains aligned with the other engineering segments of a satellite program. This article presents the status and results of this comprehensive effort to chart a course from the present set of operational satellites to the future.

    The Remedial Design Work Plan (RDWP) for Lower East Fork Poplar Creek (EFPC) Operable Unit (OU) in Oak Ridge, Tennessee. This remedial action fits into the overall Oak Ridge Reservation (ORR) cleanup strategy by addressing contaminated floodplain soil. The objective of this remedial action is to minimize the risk to human health and the environment from contaminated soil in the Lower EFPC floodplain pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Federal Facility Agreement (FFA) (1992). In accordance with the FFA, a remedial investigation (RI) (DOE 1994a) and a feasibility study (DOE 1994b) were conducted to assess contamination of the Lower EFPC and propose remediation alternatives. The remedial investigation determined that the principal contaminant is mercury, which originated from releases during Y-12 Plant operations, primarily between 1953 and 1963. The recommended alternative by the feasibility study was to excavate and dispose of floodplain soils contaminated with mercury above the remedial goal option. Following the remedial investigation/feasibility study, and also in accordance with the FFA, a proposed plan was prepared to more fully describe the proposed remedy.

    Full Text Available El artículo aborda la interpretación del Partido Comunista de Chile sobre la Dictadura de Gualberto Villarroel en Bolivia y la actuación que tuvo en ella el Movimiento Nacionalista Revolucionario, entre los años 1943 y 1946. El autor sostiene que dicha interpretación estuvo marcada por el antifascismo y por una lectura de la historia boliviana teñida de tópicos liberales. Así, el nacionalismo del MNR y los militares bolivianos  fue representado como una forma de fascismo y su actuación en el concierto latinoamericano fue interpretada bajo una óptica panamericanista, considerándola como parte de un plan del Eje para dificultar la labor de los aliados en América. En esta línea, los comunistas chilenos pugnaron por que la Cancillería chilena negara el reconocimiento al gobierno boliviano y entraron en pugna con actores políticos y sindicales chilenos proclives a conceder el reconocimiento a dicho régimen.

    The Hanford Site began operations in 1943 as one of the sites for plutonium production associated with the Manhattan Project. It has been used, in part, for nuclear reactor operation, reprocessing of spent fuel, and management of radioactive waste. The Hanford Site covers approximately 1,434 km 2 (560 mi 2 2) in southeastern Washington State. The subject of this paper, the 618-9 Burial Ground, is located on the Hanford Site approximately 1.6 km (1 mi) west of the Columbia River, and a few miles north of Richland, Washington. Throughout Hanford Site history, prior to legislation regarding disposal of chemical waste products, some chemical waste byproducts were disposed ,ia burial in trenches. One such trench was the 618-9 Burial Ground. This burial ground was suspected to contain approximately 19,000 L (5,000 gal) of uranium-contaminated organic solvent, disposed in standard 55-gal (208-L) metal drums. The waste was produced from research and development activities related to fuel reprocessing

    We demonstrate the suitability of tensor network techniques for describing the thermal evolution of lattice gauge theories. As a benchmark case, we have studied the temperature dependence of the chiral condensate in the Schwinger model, using matrix product operators to approximate the thermal equilibrium states for finite system sizes with non-zero lattice spacings. We show how these techniques allow for reliable extrapolations in bond dimension, step width, system size and lattice spacing, and for a systematic estimation and control of all error sources involved in the calculation. The reached values of the lattice spacing are small enough to capture the most challenging region of high temperatures and the final results are consistent with the analytical prediction by Sachs and Wipf over a broad temperature range.

  14. Biofuel production system with operation flexibility: Evaluation of economic and environmental performance under external disturbance

    Science.gov (United States)

    Kou, Nannan

    Biomass derived liquid hydrocarbon fuel (biofuel) has been accepted as an effective way to mitigate the reliance on petroleum and reduce the greenhouse gas emissions. An increasing demand for second generation biofuels, produced from ligno-cellulosic feedstock and compatible with current infrastructure and vehicle technologies, addresses two major challenges faced by the current US transportation sector: energy security and global warming. However, biofuel production is subject to internal disturbances (feedstock supply and commodity market) and external factors (energy market). The biofuel industry has also heavily relied on government subsidy during the early development stages. In this dissertation, I investigate how to improve the economic and environmental performance of biorefineries (and biofuel plant), as well as enhance its survivability under the external disturbances. Three types of disturbance are considered: (1) energy market fluctuation, (2) subsidy policy uncertainty, and (3) extreme weather conditions. All three factors are basically volatile, dynamic, and even unpredictable, which makes them difficult to model and have been largely ignored to date. Instead, biofuel industry and biofuel research are intensively focused on improving feedstock conversion efficiency and capital cost efficiency while assuming these advancements alone will successfully generate higher profit and thus foster the biofuel industry. The collapse of the largest corn ethanol biofuel company, Verasun Energy, in 2008 calls into question this efficiency-driven approach. A detailed analysis has revealed that although the corn ethanol plants operated by Verasun adopted the more efficient (i.e. higher ethanol yield per bushel of corn and lower capital cost) dry-mill technology, they could not maintain a fair profit margin under fluctuating market condition which made ethanol production unprofitable. This is because dry-mill plant converts a single type of biomass feedstock (corn

    The objective of this paper is to demonstrate the existence of optimal residence time and substrate inlet mass flow rate for maximum methane production through numerical simulations performed with a general transient mathematical model of an anaerobic biodigester introduced in this study. It is herein suggested a simplified model with only the most important reaction steps which are carried out by a single type of microorganisms following Monod kinetics. The mathematical model was developed for a well mixed reactor (CSTR – Continuous Stirred-Tank Reactor), considering three main reaction steps: acidogenesis, with a μ max of 8.64 day −1 and a K S of 250 mg/L, acetogenesis, with a μ max of 2.64 day −1 and a K S of 32 mg/L, and methanogenesis, with a μ max of 1.392 day −1 and a K S of 100 mg/L. The yield coefficients were 0.1-g-dry-cells/g-pollymeric compound for acidogenesis, 0.1-g-dry-cells/g-propionic acid and 0.1-g-dry-cells/g-butyric acid for acetogenesis and 0.1 g-dry-cells/g-acetic acid for methanogenesis. The model describes both the transient and the steady-state regime for several different biodigester design and operating conditions. After model experimental validation, a parametric analysis was performed. It was found that biogas production is strongly dependent on the input polymeric substrate and fermentable monomer concentrations, but fairly independent of the input propionic, acetic and butyric acid concentrations. An optimisation study was then conducted and optimal residence time and substrate inlet mass flow rate were found for maximum methane production. The optima found were very sharp, showing a sudden drop of methane mass flow rate variation from the observed maximum to zero, within a 20% range around the optimal operating parameters, which stresses the importance of their identification, no matter how complex the actual bioreactor design may be. The model is therefore expected to be a useful tool for simulation, design, control and

    1975-11-01

    Let phi 1 (x) and phi 2 (y) be two local fields in a conformal quantum field theory (CQFT) in two-dimensional spacetime. It is then shown that the vector-valued distribution phi 1 (x) phi 2 (y) /0 > is a boundary value of a vector-valued holomorphic function which is defined on a large conformally invariant domain. By group theoretical arguments alone it is proved that phi 1 (x) phi 2 (y) /0 > can be expanded into conformal partial waves. These have all the properties of a global version of Wilson's operator product expansions when applied to the vacuum state /0 >. Finally, the corresponding calculations are carried out more explicitly in the Thirring model. Here, a complete set of local conformally covariant fields is found, which is closed under vacuum expansion of any two of its elements (a vacuum expansion is an operator product expansion applied to the vacuum).

    To improve the filterability of hydroxybenzophenone crystal, a cooling strategy for the cooling crystallization process is investigated by examining the solubility and growth kinetics of hydroxybenzophenone. The operating strategy is divided into two steps. The first step is to generate the seed by dissolving the raw material and by changing operating conditions. The second step is to grow seeds to the product with desired crystal size distribution. For each part, an operating strategy has been proposed based on the solid-liquid phase equilibrium data in a ternary system and growth kinetic experimental results. The strategy for the first step is experimentally determined under various operating conditions, and the second one is determined by theoretical modeling and model-based optimization. The average crystal size resulting from the proposed strategy has been improved and the filterability has been enhanced compared to an existing strategy used in the industry.

    2007-01-01

    The economic feasibility of on-farm biogas energy production was investigated for swine and dairy operations under Nova Scotia, Canada farming conditions, using net present value (NPV), internal rate of return (IRR), and payback period (PP) economic decision criteria. In addition, the effects of selected environmental and 'green' energy policy schemes on co-generation of on-farm biogas energy production and other co-benefits from anaerobic digestion of livestock manure were investigated. Cost-efficiencies arising from economies of scale for on-farm anaerobic biogas production were found for swine farms, and less so for dairy production systems. Without incentive schemes, on-farm biogas energy production was not economically feasible across the farm size ranges studied, except for 600- and 800-sow operations. Among single policy schemes investigated, green energy credit policy schemes generated the highest financial returns, compared to cost-share and low-interest loan schemes. Combinations of multiple policies that included cost-share and green energy credit incentive schemes generated the most improvement in financial feasibility of on-farm biogas energy production, for both swine and dairy operations

    Shared Resource Laboratories (SRLs) provide investigators access to necessary scientific and resource expertise to leverage complex technologies fully for advancing high-quality biomedical research in a cost-effective manner. At the University of Nebraska Medical Center, the Flow Cytometry Research Facility (FCRF) offered access to exceptional technology, but the methods of operation were outdated and unsustainable. Whereas technology has advanced and the institute has expanded, the operations at the facility remained unchanged for 35 yr. To rectify this, at the end of 2013, we took a product lifecycle management approach to affect large operational changes and align the services offered with the SRL goal of education, as well as to provide service to researchers. These disruptive operational changes took over 10 mo to complete and allowed for independent end-user acquisition of flow cytometry data. The results have been monitored for the past 12 mo. The operational changes have had a positive impact on the quality of research, increased investigator-facility interaction, reduced stress of facility staff, and increased overall use of the resources. This product lifecycle management approach to facility operations allowed us to conceive of, design, implement, and monitor effectively the changes at the FCRF. This approach should be considered by SRL management when faced with the need for operationally disruptive measures.

  1. Coral record of variability in the upstream Kuroshio Current during 1953-2004

    The Kuroshio Current (KC), one of the most important western boundary currents in the North Pacific Ocean, strongly affects regional hydroclimate in East Asia and upper ocean thermal structure. Limited by few on-site observations, the responses of the KC to regional and remote climate forcings are still poorly understood. Here we use monthly coral δ18O data to reconstruct a KC transport record with annual to interannual resolution for the interval 1953-2004. The field site is located in southern Taiwan on the western flank of the upstream KC. Increased (reduced) KC transport would generate strong (weak) upwelling, resulting in relatively high (low) local coral δ18O. The upstream KC transport and downstream transport, off Tatsukushi Bay, Japan, covary on interannual and decadal time scales. This suggests common forcings, such as meridional drift of the North Equatorial Current bifurcation, or zonal climatic oscillations in the Pacific. The intensities of KC transport off southeastern and northeastern Taiwan are in phase before 1990 and antiphase after 1990. This difference may be due to a poleward shift of the subtropical western boundary current as a response to global warming.Plain Language SummaryThe connection between climate and oceanic circulation has long been recognized, particularly with regard to western boundary currents such as the Gulf Stream and the Kuroshio Current (KC). These systems play a crucial role in transferring solar energy from the subtropical regions to the poles. As we begin to experience the impacts of global climate change, it is critical that we understand the affect global change has on variability leading to significant changes in the structure and heat transport of such currents. Current knowledge of the KC is limited to observations over individual 10 year periods or to paleorecords of very low resolution (one sample per roughly 1000 years). Neither data set allows for a detailed understanding of the natural variability of the KC

    The fission product release during normal operation from the core of a high temperature reactor is well known to be very low. A HTR-Modul-reactor with a reduced power of 170 MW th is examined under the aspect whether the contamination with Cs-137 as most important nuclide will be so low that a helium turbine in the primary circuit is possible. The program SPTRAN is the tool for the computations and siumlations of fission product transport in HTRs. The program initially developed for computations of accident events has been enlarged for computing the fission product transport under the conditions of normal operation. The theoretical basis, the used programs and data basis are presented followed by the results of the computations. These results are explained and discussed; moreover the consequences and future possibilities of development are shown. (orig./HP) [de

    2006-01-01

    A sensitivity analysis of the operation parameters and the chemical properties in the thermochemical hydrogen production IS process (iodine-sulfur process) was carried out for a static flow sheet. These parameters were evaluated by hydrogen production thermal efficiency, the mass flow rate or heat exchange based on the heat/mass balance. The most important parameters were the concentration of HI after electro-electrodialysis (EED) and the apparent transport number of protons of the cation exchange membrane in the EED cell. HI concentration operation should be operated carefully because the parameters for optimum thermal efficiency and for the optimum flow rate and heat exchange were different. For the chemical properties, composition at the inlet of the HI decomposition procedure and HI x pseudo-azeotropic composition had great effects. The HI concentration after the EED should be optimized for each composition. The order of priority for the assessment of the operation parameters and chemical properties was determined by the evaluation. (author)

    To minimize patient risk, "bracketed" statistical quality control (SQC) is recommended in the new CLSI guidelines for SQC (C24-Ed4). Bracketed SQC requires that a QC event both precedes and follows (brackets) a group of patient samples. In optimizing a QC schedule, the frequency of QC or run size becomes an important planning consideration to maintain quality and also facilitate responsive reporting of results from continuous operation of high production analytic systems. Different plans for optimizing a bracketed SQC schedule were investigated on the basis of Parvin's model for patient risk and CLSI C24-Ed4's recommendations for establishing QC schedules. A Sigma-metric run size nomogram was used to evaluate different QC schedules for processes of different sigma performance. For high Sigma performance, an effective SQC approach is to employ a multistage QC procedure utilizing a "startup" design at the beginning of production and a "monitor" design periodically throughout production. Example QC schedules are illustrated for applications with measurement procedures having 6-σ, 5-σ, and 4-σ performance. Continuous production analyzers that demonstrate high σ performance can be effectively controlled with multistage SQC designs that employ a startup QC event followed by periodic monitoring or bracketing QC events. Such designs can be optimized to minimize the risk of harm to patients. © 2017 American Association for Clinical Chemistry.

    2015-10-27

    The electric power industry landscape is continually evolving. As emerging technologies such as wind, solar, electric vehicles, and energy storage systems become more cost-effective and present in the system, traditional power system operating strategies will need to be reevaluated. The presence of wind and solar generation (commonly referred to as variable generation) may result in an increase in the variability and uncertainty of the net load profile. One mechanism to mitigate this is to schedule and dispatch additional operating reserves. These operating reserves aim to ensure that there is enough capacity online in the system to account for the increased variability and uncertainty occurring at finer temporal resolutions. A new operating reserve strategy, referred to as flexibility reserve, has been introduced in some regions. A similar implementation is explored in this paper, and its implications on power system operations are analyzed.

    QCD sum rules at finite temperature, like the ones at zero temperature, require the coefficients of local operators, which arise in the short distance expansion of the thermal average of two-point functions of currents. We extend the configuration space method, applied earlier at zero temperature, to the case at finite temperature. We find that, upto dimension four, two new operators arise, in addition to the two appearing already in the vacuum correlation functions. It is argued that the new operators would contribute substantially to the sum rules, when the temperature is not too low. (orig.) 7 refs.

    Full Text Available In the last decade, many researchers have conducted studies on the efforts to improve corporate performance through the stimulation of specific business strategy approach. This study aims to analyze the effect of product differentiation strategy on operating performance of the company. The study was conducted on industrial of SMEs in South Sulawesi, Indonesia using a survey method with the sample of 75 respondents. The data were collected through questionnaires, and processed by the method of path analysis. The results show that the strategy of product differentiation (vertical and horizontal affects the operational performance of industrial of the SMEs significantly and negatively. It has implications such as in the early stages of the implementation of this strategy; the company can issue additional production costs in the form of material costs, and more failing products without being accompanied by an increase in new customers. This study can be continued to further examine the relationship of differentiation strategy implementation and performance of the company involving a moderator variable lag-time and the role of production technology in the research model.

    We give a formula for the derivatives of a correlation function of composite operators with respect to the parameters (i.e. the strong fine structure constant and the quark mass) of QCD in four- dimensional euclidean space. The formula is given as spatial integration of the operator conjugate to a parameter. The operator product of a composite operator and a conjugate operator has an unintegrable part, and the formula requires divergent subtractions. By imposing consistency conditions we drive a relation between the anomalous dimensions of the composite operators and the unintegrable part of the operator product coefficients. (orig.)

    Science.gov (United States)

    Widder, Joachim

    2014-07-01

    The discovery of X-rays by Wilhelm Conrad Röntgen (1845-1923) was triggered by pursuing an anomalous phenomenon: arousal of fluorescence at a distance from tubes in which cathode rays were elicited, a phenomenon which suggested the existence of a new kind of ray other than cathode rays. The discovery of biological effects of these X-rays by Leopold Freund (1868-1943) was triggered by pursuit of the purportedly useless phenomenon of epilation and dermatitis ensuing from X-ray-diagnostic experiments that others had reported. The crucial experiments performed by Robert Kienböck (1871-1953) entailed the proof that X-ray-dose, not electric phenomena, was the active agent of biological effects ensuing when illuminating the skin using Röntgen tubes. For both the discovery of X-rays and the discovery of their biological effectiveness, priority did not matter, but understanding the physical and medico-biological significance of phenomena that others had ignored as a nuisance. Present discussions about the clinical relevance of improving the dose distribution including protons and other charged particles resemble those around 1900 to a certain degree.

    The method covers the detection and measurement of delayed neutron-emitting fission products contained in nuclear reactor coolant water while the reactor is operating. The method is limited to the measurement of the delayed neutron-emitting bromine isotope of mass 87 and the delayed neutron-emitting iodine isotope of mass 137. The other delayed neutron-emitting fission products cannot be accurately distinguished from nitrogen 17, which is formed under some reactor conditions by neutron irradiation of the coolant water molecules. The method includes a description of significance, measurement variables, interferences, apparatus, sampling, calibration, standardization, sample measurement procedures, system efficiency determination, calculations, and precision

    We study operators acting on a tensor product Hilbert space and investigate their product numerical range, product numerical radius and separable numerical range. Concrete bounds for the product numerical range for Hermitian operators are derived. Product numerical range of a non-Hermitian operator forms a subset of the standard numerical range containing the barycenter of the spectrum. While the latter set is convex, the product range needs not to be convex nor simply connected. The product ...

    Full Text Available This study seeks to evaluate operational improvements in Brazilian petrochemical company Braskem, which has been using lean production management tools to monitor its processes. There was some improvement in plant efficiency, measured from the beginning of implementation of management tools Six Sigma and TPM. Thus, we investigated three efficiency indicators considered by the company of great importance for the competitiveness of the business: the physical loss of products, plant’s energy efficiency, and the utilization rate of assets. The differences observed in these indicators, before and after the use of the tools, were tested for its statistical significance, which revealed that the physical losses of ethylene and plant’s energy efficiency improved, almost reaching the performance considered as class world. As for the utilization rate of assets, although it has evolved positively, still is at a considerable distance from that performance standard. By registering operational improvements in a continuous process plant, with lean production tools, this study indicates that these instruments, even if they have no causal relation with the improvements, are suitable for continuous processes and could have a much broader use, oriented, first of all, by the general approach of process optimization and, somehow, regardless of the nature of productive activity.

  20. Management model of productive capacity: integrating theory of constraints and the global operational efficiency index (IROG

    Full Text Available This paper presents a model of management capacity in productive systems integrating the concepts of the Theory of Constraints and Total Productive Maintenance (TPM. The main objective of this study is to discuss and propose a model of management capacity, able to answer the following key questions: i capacity indicators which should be considered and how to measure them to measure the productive capacity of manufacturing systems? ii what is the real productive capacity of the system analyzed under a determined relationship between capacity and demand? The discussion of the proposed model is relevant because the definition of productive capacity system enables better management of resources and capabilities, improve production scheduling on the factory floor and meeting the demands imposed by the market. This paper presents the proposition of using the Operating Income Index Global (IROG with a different approach from traditional literature dealing with the theme, presented by Nakajima (1988. The results of this paper enable to develop a model to determine the capacity of the production system and the impact on the productive capacity of the entire system, not to consider the quality conformances that occur after the bottleneck resource of the production flow.
