This paper examines the events following the atomic bombings of Hiroshima and Nagasaki in 1945 and extrapolates from these experiences to further understand the possible consequences of detonations on a local area from weapons in the current world nuclear arsenal. The first section deals with a report of the events that occurred in Hiroshima and Nagasaki just after the 1945 bombings with respect to the physical conditions of the affected areas, the immediate effects on humans, the psychological response of the victims, and the nature of outside assistance. Because there can be no experimental data to validate the effects on cities and their populations of detonations from current weapons, the data from the actual explosions on Hiroshima and Nagasaki provide a point of departure. The second section examines possible extrapolations from and comparisons with the Hiroshima and Nagasaki experiences. The limitations of drawing upon the Hiroshima and Nagasaki experiences are discussed. A comparison is made of the scale of effects from other major disasters for urban systems, such as damages from the conventional bombings of cities during World War II, the consequences of major earthquakes, the historical effects of the Black Plague and widespread famines, and other extreme natural events. The potential effects of detonating a modern 1 MT warhead on the city of Hiroshima as it exists today are simulated. This is extended to the local effects on a targeted city from a global nuclear war, and attention is directed to problems of estimating the societal effects from such a war

The purpose is to determine by clinical investigation any late medical effects of radiation in persons exposed to the 1945 atomic bombings of the cities of Hiroshima and Nagasaki. The prevalence and incidence of certain findings were found to be different in Hiroshima and Nasasaki. For example, tuberculosis, neoplasms of the digestive organs, gastric ulcer, diseases of the thyroid, diabetes mellitus, blood diseases, and arteriosclerosis were more frequent in Hiroshima. On the other hand, syphilis, cerebrovascular accidents, intestinal parasitism, liver and kideny disease, and arthritis were more frequent in Nagasaki. The data from the hematological examinations demonstrate a decrease in hemoglobin and hematocrit with increasing age in men. In both sexes total white blood cell counts decreased with age and the values for males were higher than those for females. Total white blood cell counts in Hiroshima were higher than in Nagasaki. The need continues for superimposition of a number of epidemiologic investigations onto the basic structure of the Adult Health Study to better define and explore the differences between cities. These substudies will undoubtedly provide a more precise foundation for the study of radiation effects and further understanding of important diseases. Finally, since this study brings together scientists from two parts of the world, patterns of disease detected in Japan inevitably were compared with personal and published experience in the United States. Many suspected differences between these countries have been commented upon in the medical literature. The Adult Health Study is contributing data which will establish or deny these differences. 147 references, 18 figures, 35 tables.

Sulfur activation in Hiroshima

Kerr, G.D.; Pace, J.V. III.

1987-01-01

In 1979, we attempted to establish the validity of source terms for the Hiroshima and Nagasaki bombs using experimental data on sulfur activation. Close agreement was observed between measured and calculated values for test firings of Nagasaki-type bombs. The calculated values were based on source terms developed by W.E. Preeg at the Los Alamos National Laboratory (LANL). A discrepancy was found, however, when we compared calculated values for the two bombs because a 1956 report by R.R. Wilson stated that sulfur acitvation by fast neutrons in Hiroshima was approximately three times greater than in Nagasaki. Our calculations based on Preeg's source-term data predicted about equal sulfur activation in the two cities

The Hiroshima neutron dosimetry enigma: Missing puzzle piece No. 6

International Nuclear Information System (INIS)

Gold, Raymond

1999-01-01

More than a decade has elapsed since the serious nature of the discrepancy between neutron dosimetry experiments (E) and neutron transport calculations (C) for the Hiroshima site was identified. Since that time extensive efforts to resolve this Hiroshima neutron dosimetry enigma have not only failed, but now demonstrate that the magnitude of this discrepancy is much greater than initially estimated. The currently evaluated E/C ratio for thermal neutron fluence at the Hiroshima site increases rapidly with increasing slant range from the epicenter. In the slant range region beyond 1000 m, E/C exceeds unity by one to two orders of magnitude depending on the specific dosimetry data that are utilized. Principal features that characterize the Hiroshima neutron dosimetry enigma are summarized. Puzzle Piece No. 6: In-situ production and Prompt fallout of radionuclides from Little Boy is advanced as a possible contributory phenomenon to this enigma. (The atom bomb detonated over Hiroshima was called Little Boy.) Measurements of 60 Co and 152 Eu specific activity at the Hiroshima site are used to obtain order of magnitude numerical estimates that show this conjecture is plausible. Comparison of different 60 Co measurements at the Hiroshima site reveals that the variation of E/C with slant range depends on the method used to quantify 60 Co specific activity as well as the type of dosimetry samples that are employed. These 60 Co comparisons lend additional qualitative credence to this conjecture. Within the limits of presently available data, these assessments show that Puzzle Piece No. 6 qualitatively satisfies the principal features that characterize the Hiroshima neutron dosimetry enigma. Nevertheless, current lack of data prevent this conjecture from being conclusively confirmed or refuted. Consequently, specific recommendations are advanced to resolve the Hiroshima neutron dosimetry enigma with emphasis on experimental tests that can quantitatively evaluate Puzzle Piece

Relation of radiation of gastric carcinoma observed in autopsy cases in a fixed population Hiroshima and Nagasaki

Shimizu, Y; Yamamoto, T [Radiation Effect Research Foundation (Japan)

1976-03-01

The relationship between exposure dose and the occurrence of stomach cancer, especially the histological type of the cancer was studied in 535 autopsy cases which had died of stomach cancer from 1961 to 1974 in the Radiation Effect Research Foundation. The incidence of stomach cancer tended to be higher in the group with high exposure dose in Hiroshima, and only in the group with 300 - 399 rads in Nagasaki. The relationship between the incidence of stomach cancer by age at the exposure and the exposure dose was studied by the relative risk (200-499 rads/ 0 rads) of the incidence of stomach cancer by age. The relative risk was 1.56 in the group which had been more than 50 years old at exposure in both Hiroshima and Nagasaki. The risk of stomach cancer was higher in more aged persons at the exposure. From the aspect of the relationship between histological type of stomach cancer and exposure dose, the incidence of intestinal type or diffuse type tended to be higher in the persons who had much more doses. Because there were small number of cases, there was no statistically significant differences between the incidence of stomach cancer and the exposure dose.

Further, an account on the powder from the Bikini H-bomb explosion is given. Finally, the author protests against the military uses of nuclear energy.

Cancer risk among atomic bomb survivors. The RERF Life Span Study. Radiation Effects Research Foundation

International Nuclear Information System (INIS)

Shimizu, Y.; Schull, W.J.; Kato, H.

1990-01-01

This article summarizes the risk of cancer among the survivors of the atomic bombing of Hiroshima and Nagasaki. We focus primarily on the risk of death from cancer among individuals in the Life Span Study sample of the Radiation Effects Research Foundation from 1950 through 1985 based on recently revised dosimetry procedures. We report the risk of cancer other than leukemia among the atomic bomb survivors. We note that the number of excess deaths of radiation-induced malignant tumors other than leukemia increases with age. Survivors who were exposed in the first or second decade of life have just entered the cancer-prone age and have so far exhibited a high relative risk in association with radiation dose. Whether the elevated risk will continue or will fall with time is not yet clear, although some evidence suggests that the risk may be declining. It is important to continue long-term follow-up of this cohort to document the changes with time since exposure and to provide direct rather than projected risks over the lifetime of an exposed individual

Mathematical phantoms for use in dose estimation of survivors in Hiroshima and Nagasaki

The T65D (Tentative 1965 Dose) was recently revised on the basis of new scientific evidences which were available in accordance with the development of computer techniques and the accumulation of nuclear data. For the dose determinations of survivors in Hiroshima and Nagasaki, DS86 (Dosimetric System 1986) is a complete replacement of T65D for the Life Span Study (LSS) in RERF (Radiation Effects Research Foundation). In the DS86, depending on the input data for a survivor, various elements of several data bases are combined to provide the dosimetric variables requested by the user. The quantity finally desired for the LSS is absorbed dose in each organ. The calculation of quantities for converting incident fluence to absorbed dose in the target organ was carried out using Monte Carlo methods. For this calculation, mathematical phantoms were required. This paper describes the background data used for the construction of Japanese survivor phantoms and summarizes the mathematical phantoms employed in the DS86. (author)

1978-01-01

The presence of chimaerism in peripheral lymphocyte chromosome 21 years after A-bomb radiation was examined using 16 males who had been exposed in-utero to radiation from A-bomb in Hiroshima and Nagasaki. (10 cases in Hiroshima and 6 cases in Nagasaki). At the same time, doses of in-utero radiation were estimated. It was found that no cells possess XX chromosome by observing 1,600 chromosome metaphases in 16 cases (100 per a person). Estimated dose of in-utero radiation was 44 - 151 rad, or 75.6 rad on the average for 10 cases in Hiroshima and 61 - 197 rad, or 104 rad on the average for 6 cases in Nagasaki. Estimated radiation dose of their mothers used as a basis for estimating in-utero radiation dose was 120 - 149 rad or 207.9 rad on the average for cases in Hiroshima and 148 - 477 rad or 251 rad on the average for cases in Nagasaki. A ratio of total dose given to mother to that given to fetus was 2.75 in cases of Hiroshima and 2.41 in those of Nagasaki. (Iwagami, H.)

Residual radiation in Hiroshima and Nagasaki

Arakawa, E T

These results show that the fission product fallout and neutron-induced radioactive isotopes can be separated very conveniently by locations in the city, i.e., the fallout occurred in the Koi-Takasu area of Hiroshima and the Nishiyama area of Nagasaki with negligible fallout in the hypocenter area. The activity in the hypocenter areas of both cities can be accounted for as due principally to neutron induced radioactive isotopes. The maximum exposure from fallout in Hiroshima is considered to have been a few r and in Nagasaki approximately 30 r. From one hour to infinite time after the detonations, the maximum possible neutron induced radiation exposure dose at the hypocenter in Hiroshima is estimated to be in the range from 183 r to 24 r, depending upon the method of calculation. Method III, which yileds 24 r appears to be subject to the least number of uncertainties and thus is the most reliable figure. The excellent agreement between these calculations and the measured activities also further supports the soundness of Method III. This method gives 4 r as the infinity dose at the hypocenter in Nagasaki. These values are considered to be of such loss magnitude as to be of negligible consequence. It should also be emphasized that even for the calculation which yields a maximum dose of 183 r, the probability of an individual being exposed to this dose is very small. These facts suggest that after the detonations in Hiroshima and Nagasaki radiation levels were such that very few individuals, if any, received significant amounts of residual radiation from external sources. 17 references, 4 figures, 3 tables.

Studies of population change of Japanese Atomic Bomb Survivors from 1965 to 1979 in Hiroshima prefecture of which registered in Data Base of Atomic Bomb Survivors of RINMB were conducted, and following were obtained: 1. Population change of Japanese Atomic Bomb Survivors showed increasing trend until 1976 and diminishing trend from 1977. It would be estimated that reason of increasing trend of Atomic Bomb Survivors was correlated the same trend to get register card of ''Atomic Bomb Treatment Law'', and decreasing trend of them was related so much death of the elderly generations. 2. Analysing by residential place the survivors who make a living in Hiroshima city was almost 110,000, and those who make a living in Hiroshima prefecture (except Hiroshima city) was 65,000. Considering exposed distance of the survivors in Hiroshima city, those survivors exposed within 2 km showed diminishing trend; and those who make a living in Hiroshima prefecture (except Hiroshima city), exposed within 2 km showed increasing trend. 3. In 1979, the ratio of male and female survivors by age level showed difference. Those male survivors over 50 years old in Hiroshima city showed much lower percentage than female. 4. In 1979, the population trends of survivors who get the ''card'' before 1964 showed rapid decrease, and those who get the ''card'' after 1965 showed mild decrease. (author)

Statistical aspects of tumor registries, Hiroshima and Nagasaki

Ishida, M

1961-02-24

Statistical considerations are presented on the tumor registries established for purpose of studying radiation induced carcinoma in Hiroshima and Nagasaki by observing tumors developing in the survivors of these cities. In addition to describing the background and purpose of the tumor registries the report consists of two parts: (1) accuracy of reported tumor cases and (2) statistical aspects of the incidence of tumors based both on a current population and on a fixed sample. Under the heading background, discussion includes the difficulties in attaining complete registration; the various problems associated with the tumor registries; and the special characteristics of tumor registries in Hiroshima and Nagasaki. Beye's a posteriori probability formula was applied to the Type I and Type II errors in the autopsy data of Hiroshima ABCC. (Type I, diagnosis of what is not cancer as cancer; Type II, diagnosis of what is cancer as noncancer.) Finally, the report discussed the difficulties in estimating a current population of survivors; the advantages and disadvantages of analyses based on a fixed sample and on an estimated current population; the comparison of incidence rates based on these populations using the 20 months' data of the tumor registry in Hiroshima; and the sample size required for studying radiation induced carcinoma. 10 references, 1 figure, 8 tables.

Shintani, Takahiro; Hayakawa, Norihiko; Hoshi, Masaharu

1999-01-01

Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundred and seven non-exposed patients with meningioma were also studied. Treatment dates were from 1975 to 1992. The incidences of meningioma among 68 subjects within 2.0 km and 607 non-exposed patients were 8.7 and 3.0 cases per 10 5 persons per year, respectively. The incidences of meningioma among the survivors of Hiroshima in 5-year intervals since 1975 were 5.3, 7.4, 10.1, and 14.9, respectively. The incidences of meningioma classified by distances from the hypocenter of 1.5-2.0 km, 1.0-1.5 km and less than 1.0 km were 6.3, 7.6 and 20.0, respectively. The incidences of meningioma classified by doses to the brain of 0-0.099 Sv, 0.1-0.99 Sv and more than 1.0 Sv were 7.7, 9.2 and 18.2, respectively. The incidence of meningioma among Hiroshima atomic bomb survivors has increased since 1975. There was a significant correlation between the incidence and the dose of radiation to the brain. The present findings strongly suggest that meningioma is one of the tumors induced by atomic bombing in Hiroshima. (author)

In 1945 Shuntaro Hida was a young doctor. In a village at the periphery of Hiroshima he survived and he immediately began caring for victims. He has (recently?) written an eye-witness account, of which in a Western language apparently only a manuscript exists. I have extracted a few passages from the document of 41 pages. A few spelling and typing errors were corrected. - Be it added that many of the atomic weapons now in the arsenals of the powers are more than a thousand times stronger than the bomb of Hiroshima. Some 60.000 atomic weapons are thought to exist. (author)

Data have been presented on the finding of glycosuria and the diagnosis of diabetes mellitus during four years of a long-term study of the health of population samples of Hiroshima and Nagasaki. Diabetes and glycosuria are much more common in Hiroshima than in Nagasaki and in both cities these findings are more frequent in males than in females. The prevalence of diabetes appears to be increasing in Hiroshima males. Findings in diabetics were compared with nondiabetics. In general, Japanese diabetics are similar to diabetics in other countries concerning their increased risk of obesity, hypertension, proteinuria, hypercholesterolemia, and cardiovascular and cerebrovascular diagnoses. This is of particular interest in the light of evidence that ketosis and severe abnormalities of carbohydrate metabolism are rare in Japan as compared to Western countries. Despite a lower prevalance of diabetes in Japanese females than in males, the abnormalities associated with diabetes appear to occur more commonly in female diabetics than in male diabetics.

The so called peaceful use of atomic power is an ideology specifically apt for appeasement in an illusionary way: although everyone could know about the desastrous effects of radioactivity since Hiroshima and Nagasaki, the civil use of atomic power serves to demonstrate, that the incompatibility of radionuclides with health and life could be controlled and mastered. In this context the civil use of atomic power appears as an instrument of social control. (orig.) [de

The presence of chimaerism in peripheral lymphocyte chromosome 21 years after A-bomb radiation was examined using 16 males who had been exposed in-utero to radiation from A-bomb in Hiroshima and Nagasaki. (10 cases in Hiroshima and 6 cases in Nagasaki). At the same time, doses of in-utero radiation were estimated. It was found that no cells possess XX chromosome by observing 1,600 chromosome metaphases in 16 cases (100 per a person). Estimated dose of in-utero radiation was 44 - 151 rad, or 75.6 rad on the average for 10 cases in Hiroshima and 61 - 197 rad, or 104 rad on the average for 6 cases in Nagasaki. Estimated radiation dose of their mothers used as a basis for estimating in-utero radiation dose was 120 - 149 rad or 207.9 rad on the average for cases in Hiroshima and 148 - 477 rad or 251 rad on the average for cases in Nagasaki. A ratio of total dose given to mother to that given to fetus was 2.75 in cases of Hiroshima and 2.41 in those of Nagasaki.

Orthopaedic research and education foundation and industry.

Wurth, Gene R; Sherr, Judy H; Coffman, Thomas M

2003-07-01

Members of orthopaedic industry commit a significant amount of funds each year to support research and education programs that are directly related to their product(s). In addition, industry supports organizations such as the Orthopaedic Research and Education Foundation. The relationship between the Orthopaedic Research and Education Foundation and industry began in the early 1980s. The support to the Orthopaedic Research and Education Foundation from industry primarily has come in the form of unrestricted grants. These grants best can be looked at as an investment rather than a contribution. This form of giving, once called corporate philanthropy is more accurately referred to as strategic philanthropy. Members of industry make these investments to enhance their reputations, build brand awareness, market their products and services, improve employee morale, increase customer loyalty, and establish strategic alliances. The specialty of orthopaedics is among the leaders in medicine in the amount of funding raised within the specialty for research and education programs. This is because of the amount of support from members of industry and the surgeons. During the past 15 years, 40% of the annual support to the Orthopaedic Research and Education Foundation has come from industry and the balance has come from surgeons and members of lay public. Future industry support of the Orthopaedic Research and Education Foundation and other organizations within the specialty of orthopaedics will be dependent on the continued demonstration of tangible returns in areas described.

A panel of Japanese and American pathologists reviewed existing histologic material used to study breast cancer risk among the A-bomb survivors in Hiroshima and Nagasaki, a population in which incidence studies have found a strong relationship between breast cancer risk and radiation dose. The primary charge to the panel was to define a body of confirmed cases in the Life Span Study sample of the Radiation Effects Research Foundation that would require little or no review for inclusion in future studies of breast cancer incidence. Broad agreement on histologic type was reached for 298 of 300 confirmed cases. The distribution of histologic types was, overall, similar to that seen in other studies of breast cancer in Japanese women, and did not appear to depend on dose; thus radiation-induced breast cancer appeared to be no different histologically from other breast cancer. Also, no evidence was found of variation in histologic type by city, age at exposure, age at diagnosis, or calendar time

Dental radiography exposure of the Hiroshima and Nagasaki populations

Antoku, Shigetoshi; Hoshi, Masaharu; Russell, W.J.

1987-04-01

Dental radiography doses in Hiroshima and Nagasaki were estimated using doses measured by a thermoluminescent dosimeter and a phantom, and survey data from dental hospitals and clinics in Hiroshima and Nagasaki. Doses to organs, including the lens, pituitary fossa, thyroid gland, and skin were calculated. Average doses per examination to these body sites were calculated using data obtained during a two-week survey in both cities. The mean caput doses were calculated from the data indicating frequency per year, and were tabulated by organ, age, teeth examined, type of examination, population, sex, and city. No significant difference was observed by age, population, sex, or city. Currently, the doses incurred during dental radiography may not be sufficiently high to cause bias in the assessments for late radiation effects among atomic bomb survivors. However, the mean caput thyroid doses of 62 mrad and 67 mrad in Hiroshima and Nagasaki, respectively, cannot be ignored from the standpoint of their potential in contributing to radiation-induced carcinogenesis.

1981-09-01

The Los Alamos efforts related to resolution of the Hiroshima, Nagasaki doses are described as follows: (1) Using recently located replicas of the Hiroshima bomb, measurements will be made which will define the upper limit of the Hiroshima yield. (2) Two-dimensional calculations of the neutron and gamma-ray outputs of the Hiroshima and Nagasaki weapons are in progress. Neutron and gamma-ray leakage spectra measurements will be made. Similar measurements on the Mark 9 weapon and on the Ichiban assembly are proposed. These measurements will provide a check for present day cross sections and calculations. (3) Calculations of several air transport experiments are in progress. A comparison of calculated results with experimental results is given. (4) The neutron and gamma-ray output spectra of several devices tested in the atmosphere at the Nevada Test Site are being calculated. The results of these calculations will allow models of the debris cloud contribution to the total dose to be tested

Activities of the National Academy of Sciences in relation to the Radiation Effects Research Foundation

The activities of the National Academy of Sciences (NAS), in relation to the Radiation Effects Research Foundation (RERF), has a long history and the specific time period supported by this contract is but a small piece of the long-term continuing program. As a background, in August 1945, atomic bombs were dropped on Hiroshima (6 August) and Nagasaki (9 August). Shortly after the bombings, US medical teams joined forces with their Japanese counterparts to form a Joint Commission for the Investigation of the Effects of the Atomic Bombs. As a result of the Joint Commission's investigations, it was determined that consideration should be given to the establishment of a long-term study of the potential late health effects of exposure of the survivors to radiation from the bombs. The results obtained from RERF studies contribute the vast majority of information that provides a better understanding of radiation effects on humans. This information has been used extensively by national organizations and international committees for estimating risks associated with radiation exposures. The estimated risks developed by these independent organizations are used by government agencies around the world to establish standards for protection of individuals exposed in the occupational, medical, and general environment. Some of these results are described briefly in this report

An overview of some aspects of psycho social readaptation of the atomic bomb survivors in Hiroshima is presented. Reports from 31 survivors, 8 men and 23 women, were used as data for the analysis. The reports were collected individually through a structured interview, in one of the two hospitals in Hiroshima which deliver services to the survivors. The data were grouped according to the following areas: family, work, health and psychological readaptation. These data were analysed considering the psycho social aspects of disasters and the characteristics of the japanese culture. (M.A.C.)

After Japan surrendered in August 1945, a team of Los Alamos scientists entered both Hiroshima and Nagasaki to assess the damage of Little Boy and Fat Man. Two of these scientists, Berlyn Brixner and Edwin McMillan, discovered a stock of photographic film in Hiroshima that had been fogged by the gamma radiation from Little Boy. They devised an experiment that they thought might be used to determine the exposure levels in the city. Below is both their description of the film stock and the attempt to determine the exposure levels at Hiroshima.

Cancer risks and neutron RBE's from Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Dobson, R.L.; Straume, T.

1982-01-01

The new radiation dose estimates for Hiroshima and Nagasaki are radiobiologically examined for compatability with other human and experimental data. The new doses show certain improvements over the original T65 doses. However, they suggest for chronic granulocytic leukemia, total malignancies, and chromosome aberrations, at neutron doses of 1 rad, RBEs in excess of 100, higher than expected from other findings. This and other indications suggest that either there are unrecognized systematic problems with the various radiobiological data, or the new doses are deficient in neutrons for Hiroshima, by a factor of about five. If in fact there were actually some 5-fold more dose from neutrons at Hiroshima than estimated by the new calculations, the RBEs would agree well with laboratory results, and other inconsistencies would largely disappear. Cancer risks are estimated for neutrons from the new doses and are compared with those estimated from radiobiologically reconciled doses (the new doses adjusted by adding approximately 5-fold more neutrons). The latter appear more reasonable. For low-LET radiation, cancer risk estimates are changed very little by the new dose estimates for Nagasaki

For children irradiated in utero and nonirradiated children of Hiroshima hematologic findings between the years 1950 to 1957 have been compared, and no changes peculiar to the irradiated group were found. Despite several predisposing factors toward the development of iron deficiency in Japanese children, overt anemia was rare and distribution of hemoglobin levels was only slightly lower than reported for American and European children. Leukocyte levels, irrespective of age of the children, were found to be progressively falling in Hiroshima children so that by 1957 the values were distinctly lower than those reported for normal children in Japan and the United States. No cause for this change was apparent. 19 references, 7 figures, 3 tables.

Cancer risk among children of atomic bomb survivors. A review of RERF epidemiologic studies. Radiation Effects Research Foundation

International Nuclear Information System (INIS)

Yoshimoto, Y.

1990-01-01

This article summarizes recent epidemiologic studies of cancer risk among the children of atomic bomb survivors conducted at the Radiation Effects Research Foundation. These children include two groups: (1) the in utero-exposed children (ie, those born to mothers who had been pregnant at the time of the bombings of Hiroshima and Nagasaki) and (2) the F1 population, which was conceived after the atomic-bombings and born to parents of whom one or both were atomic bomb survivors. Although from 1950 to 1984 only 18 cancer cases were identified among the in utero sample, cancer risk did appear to significantly increase as maternal uterine dose increased. However, since the observed cases are too few in number to allow a site-specific review, the increased cancer risk cannot be definitively attributed to atomic bomb radiation, as yet. For those members of the F1 population who were less than 20 years old between 1946 and 1982, cancer risk did not appear to increase significantly as parental gonadal dose increased. Follow-up of this population will continue to determine if the patterns of adult-onset cancer are altered

Activities and future plans of the radiation effects research foundation

The Radiation Effects Research Foundation (RERF) was established in 1975 as a binational research foundation supported by Japan and the United States. It continues the work of the Atomic Bomb Casualty Commission (ABCC) which was established in 1974. ABCC-RERF studies focus on several fixed cohorts of survivors and their children: the Life Span Study (LSS) cohort (120,000 survivors); the In-Utero cohort (3,300 people born within 9 months of the bombings); the F 1 cohort (88,000 people born between mid-1946 and 1984), and the Adult Health Study (AHS) cohort (an ongoing clinical study of 17,000 LSS survivors and 1,100 people exposed in-utero). Epidemiological data have shown increased risks of leukemia and solid cancers by radiation exposure among the survivors. Excess leukemia risks, especially for children, were markedly elevated 5 to 10 years after exposure and have continued at reduced levels. Excess solid cancer rates became apparent within 10 years after exposure, increasing throughout life in rough proportion to background rates. For doses of interest in radiation protection excess leukemia risks exhibit an upward curving dose response pattern while the solid cancer excess appears to be linear by dose with no apparent threshold. In addition to malignancy, AHS data has shown dose-related increased risk for various non-malignant diseases; radiation cataracts, benign tumors of uterus, thyroid and parathyroid (hyperparathyroidism), and autoimmune thyroid diseases. Persons exposed in-utero exhibit a broad range of dose-related effects including delayed growth and development and higher rates of microcephaly. Studies of birth defects, chromosome aberrations, childhood mortality, and genetic variants of serum or erythrocyte proteins have provided no indication of heritable mutations in the F 1 cohort. Continued follow-up of survivors exposed as children (90% are still alive) is essential to understanding the temporal pattern of excess risks and lifetime risks, and may

A simple screening method for blood bactericidal activity was developed for study of irradiated atomic bomb survivors and nonirradiated subjects in Hiroshima. Blood bactericidal activity was found to be a relatively constant biological phenomenon in all subjects studied. No differences in activity were detected in relationship to radiation exposure in 1945. 17 references, 6 tables.

The present paper presents the {sup 36}Cl measurement effort in the US. A large number of {sup 36}Cl measurements have been made in both granite and concrete samples obtained from various locations and distances in Hiroshima and Nagasaki. These measurements employed accelerator mass spectrometry (AMS) to quantify the number of atoms of {sup 36}Cl per atom of total Cl in the sample. Results from these measurements are presented here and discussed in the context of the DS02 dosimetry reevaluation effort for Hiroshima and Nagasaki atomic-bomb survivors. The production of {sup 36}Cl by bomb neutrons in mineral samples from Hiroshima and Nagasaki was primarily via the reaction {sup 35}Cl(n,{gamma}){sup 36}Cl. This reaction has a substantial thermal neutron cross-section (43.6 b at 0.025 eV) and the product has a long half-life (301,000 y). hence, it is well suited for neutron-activation detection in Hiroshima and Nagasaki using AMS more than 50 years after the bombings. A less important reaction for bomb neutrons, {sup 39}K(n,{alpha}){sup 36}Cl, typically produces less than 10% of the {sup 36}Cl in mineral samples such as granite and concrete, which contain {approx} 2% potassium. In 1988, only a year after the publication of the DS86 final report (Roesch 1987), it was demonstrated experimentally that {sup 36}Cl measured using AMS should be able to detect the thermal neutron fluences at the large distances most relevant to the A-bomb survivor dosimetry. Subsequent measurements in mineral samples from both Hiroshima and Nagasaki validated the experimental findings. The potential utility of {sup 36}Cl as a thermal neutron detector in Hiroshima was first presented by Haberstock et al. who employed the Munich AMS facility to measure {sup 36}Cl/Cl ratios in a gravestone from near the hypocenter. That work subsequently resulted in an expanded {sup 36}Cl effort in Germany that paralleled the US work. More recently, there have also been {sup 36}Cl measurements made by a Japanese

Incidence of leukemia in survivors of the atomic bomb in Hiroshima and Nagasaki, Japan

This document contains two reports. The aim of the first investigation was to obtain information concerning all individuals in Hiroshima and Nagasaki having onset of symptoms of leukemia or dying of the disease since the atomic explosion in 1945. Results show that: (1) There is a significant increase in the incidence of leukemia in the exposed populations of Hiroshima and Nagasaki as compared with the non-exposed populations of the two cities; (2) there is a significant increase in the incidence of leukemia within the exposed population of Hiroshima and Nagasaki in subjects exposed at distances less than 2000 meters from the hypocenter; and (3) The concept that radiation from the atomic bomb explosions in Hiroshima and Nagasaki is a leukemogenic agent in man is supported. In the second report, 10 patients were used to study the early hematologic and preclinical phases of leukemia in atomic bomb survivors. Findings are presented. 23 references, 13 figures, 15 tables.

In light of the findings from a test carried out on 72216 children born from parents who felt the bomb radiation at Hiroshima and Nagasaki, it appears that humans are less sensitive to genetic effects of radiation that previously thought. The new assessment of radiation's effect has not found an increase in birth defects, in chromosomal abnormalities in white blood cells or in cancer in the victim's children. However, it is assumed that as they enter their 50s, they may suffer the long-delayed consequences of the bomb. ills

From History to Memory: Alain Resnais’ and Marguerite Duras’ Hiroshima mon amour

Directory of Open Access Journals (Sweden)

Sarah French

2008-12-01

Full Text Available This paper examines the representation of history and memory in Alain Resnais’ and Marguerite Duras’ 1959 film Hiroshima mon amour. It argues that the film’s privileging of subjective remembrance reflects a broader cultural interest in using memory as a counter discourse to established history. The widely documented cultural preoccupation with memory became particularly prominent in the early 1980s. However, Hiroshima mon amour can be read as an important early example of a film that predates the contemporary ‘memory boom’. For Resnais and Duras, the magnitude of the devastation in Hiroshima exceeds the limits of filmic representation. Their solution to the problem that the historic event is unrepresentable is to approach the event indirectly while focusing on an individual traumatic memory. Through a close analysis and critique of the film I argue that the film’s emphasis on individual memory validates the legitimacy of the personal narrative but problematically subsumes the political events and displaces history from the discursive realm. I also suggest that problems emerge in the film’s depiction of its traumatised female subject. While Hiroshima mon amour represents a complex female subjectivity and interiority, the process of remembrance depicted deprives the woman of agency and renders her trapped within a compulsive repetition of the past.

36Cl measurements of Hiroshima concrete samples

The 36 Cl AMS studies are reported. A new steps of procedure of a sample preparation is developed and a tremendous reduction of sulphur background has been achieved. The 36 Cl contents of two atomic bombed concrete samples, old Hiroshima Bank one and Gokoku Shrine one, have been measured as a function of 36 Cl to Cl ratio by the Tsukuba AMS system. The 36 Cl to Cl ratio of the old Hiroshima Bank sample shows very nice agreement with the result of γ measurement of 152 Eu. Otherwise, the ratio is about 20% smaller than an estimation by the DS86 dosimetry system. A result of the Gokoku Shrine sample is also smaller than a depth profile estimation by the same DS86. It might be clear that the DS86 has a tendency of overestimation. It seems that a calculation method and/or the parameters used in the calculation are requested to be improved. (author)

Doses from Hiroshima mass radiologic gastric surveys

Antoku, S; Sawada, S; Russell, W J [Radiation Effects Research Foundation, Hiroshima (Japan)

1980-05-01

Doses to examinees from mass radiologic surveys of the stomach in Hiroshima Perfecture were estimated by surveying for the frequency of the examinations, and for the technical factors used in them, and by phantom dosimetry. The average surface, active bone marrow and male and female gonad doses per examination were 5.73 rad, 231 mrad, and 20.6 and 140 mrad, respectively. These data will be used in estimating doses from medical X-rays among atomic bomb survivors. By applying them to the Hiroshima population, the genetically significant, per caput mean marrow, and leukemia significant doses were 0.14,8.6 and 7.4 mrad, respectively. There was a benefit-to risk ratio of about 50 for mass gastric surveys performed in 1976. However, the calculated risk was greater than the benefit for examinees under 29 years of age because of the lower incidence of gastric cancer in those under 29 years.

Biological and physical surveys were conducted in order to investigate the relationship between environmental conditions and the distribution of moon jellyfish Aurelia aurita in Hiroshima Bay, western Seto Inland Sea, Japan. Moon jellyfish and ichthyoplankton were collected at 13 stations in Hiroshima Bay during monthly surveys from July to September in 2006 and 2007. Surface temperature in 2006 was significantly lower during the August and September cruises and surface salinity was lower during all cruises than in 2007. Moon jellyfish was the most dominant gelatinous plankton collected, accounting for 89.7% in wet weight. Mean moon jellyfish abundance in 2006 was higher than that in 2007 from July through September, with significant inter-year differences for July and September. Variability in precipitation and nutritional input from the Ohta River, northernmost part of Hiroshima Bay, were suggested as possible factors affecting the inter-annual variability in moon jellyfish abundance in the coastal areas of northern Hiroshima Bay. Moon jellyfish were more abundant in the coastal areas of northern Hiroshima Bay, where the dissolved oxygen (DO) concentration was lower, while low in the central part of the bay. Japanese anchovy Engraulis japonicus eggs were most dominant (58.1% in number) among the ichthyoplankton and were abundant in the central area of Hiroshima Bay. Explanatory analysis was conducted to detect possible effects of environmental conditions on the abundance of moon jellyfish and Japanese anchovy eggs during the summer months in Hiroshima Bay. Of the environmental conditions tested (temperature, salinity and DO of surface and bottom layers at each sampling station), bottom DO had the most significant effect on the moon jellyfish abundance: there was a negative correlation between the bottom DO and the moon jellyfish abundance in Hiroshima Bay during summer.

Post-Foundational Discourse Analysis: A Suggestion for a Research Program

Tomas Marttila

2015-08-01

Full Text Available Post-foundational discourse analysis, also labeled as Essex School in Discourse Analysis, has been observed to suffer from a considerable methodological deficit that limits its applicability in empirical research. The principal aim of this article is to overcome this methodological deficit by constructing the research program of the post-foundational discourse analysis that facilitates its operationalization in empirical research. In accordance with Imre LAKATOS (1970 and David HOWARTH (2004a, a research program is referred to an internally consistent and openly scrutinizable system of theoretical, methodological and phenomenal concepts that opens up the possibility to distinguish between the "negative" and the "positive" heuristics of empirical research. The first three sections develop the positive heuristics of the post-foundational discourse analysis by elucidating its theoretical foundations, methodological position and phenomenal framework. The concluding fourth section draws on the presented positive heuristics to outline the analytical stages and strategies of the post-foundational discourse analysis and discusses suitable methods for sampling and interpreting empirical data.

Fifty years after Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Nishiwaki, Y.

1996-01-01

The initial radiation was composed primarily of gamma rays and neutrons. Several estimates have in the past been advanced for the initial dose of radiation. The tentative T65D dose estimates (established in 1965) were revised in July 1987 by the US-Japan Committee for Reassessment of Atomic Bomb Radiation Dosimetry in Hiroshima and Nagasaki, and the new DS86 dosimetry system was adopted. However, there may still be various uncertainties involved. The uncertainties under emergency conditions, in particular, the uncertainties in estimating dose-effect, relationships in Hiroshima and Nagasaki have been repeatedly discussed by professor Nishiwaki since the first meeting on the medical and pathological effects of atomic bombings held at the Department of Pathology of the late Professor Ryojun Kinoshita, the then Professor of pathology, Faculty of Medicine of Osaka University in 1945. The survivors and those who visited Hiroshima immediately after the atomic bombing could have been subjected in a number of other possible noxious effects in addition to atomic radiation. Hospitals, laboratories, drugstores, chemists, pharmaceutical works, storehouses of chemicals, factories, etc. that were situated close to the hypocenter were all completely destroyed and various mutagenic, carcinogenic or teratogenic substances must have been released. There was no medical care and no food in the region of high dose exposure and the drinking water was contaminated. There would have been various possibilities of infection. Mental stress would also have been much higher in the survivors closer to the hypocenter. It is confusing which factor played a dominant role. In addition, there would be problems in accurately recording the position of the exposed persons at the time of the atomic bombing and also in estimating the shielding factors. There may be considerable uncertainty in human memory under such conditions. It is also possible that there could have been a large storage of gasoline to

A two-year ophthalmologic study of age- and radiation-related ophthalmologic lesions among the Adult Health Study (AHS) population of Hiroshima and Nagasaki was conducted at RERF in 1978-80. The study population in both cities was composed of all persons exposed to 100+ rad in the AHS, their controls, and all other persons in the AHS sample with a previous record of axial opacities or posterior subcapsular changes, and the in utero clinical sample. The ophthalmologic examination was conducted on 1,582 persons in Hiroshima and 719 persons in Nagasaki belonging to the AHS sample, and 67 persons in Hiroshima and 17 persons in Nagasaki belonging to the in utero clinical sample. Participation in the study was 42% of the eligible AHS sample in Hiroshima and 21% in Nagasaki, and 24% of the eligible in utero sample in Hiroshima and 26% in Nagasaki. Increased lenticular opacities, other lens changes, and loss of visual acuity and accommodation occurred with increasing age in both exposed and control subjects as manifestations of the normal aging process. A highly significant excess risk for all ages in the 300+ rad group in comparison to those in the control group was observed for both axial opacities and posterior subcapsular changes in Hiroshima, but not in Nagasaki.

Based upon the data obtained by the Interim Urban Population Survey conducted on October 1, 1958, in the cities of Hiroshima Prefecture, a comparison has been made between the demographic characteristics of the Hiroshima City atomic bomb survivors and those of the nonexposed. Analysis of the data revealed: (1) the estimated number of persons exposed to the Hiroshima atomic bomb and still residing in Hiroshima City on October 1, 1958 was 92,180; (2) the annual mean rates of in-migration and out-migration of the exposed population during the eight year period from 1950 to 1958 were both approximately 2%, while those for the nonexposed were 8% and 4% respectively; (3) the rate of unmarried exposed females tended to be higher than the rate of unmarried women not exposed, while no difference was noted for single males by exposure status; (4) proportionately greater numbers of exposed persons were engaged in primary and secondary industries (agriculture and manufacturing), while a proportionately greater number of nonexposed were engaged in tertiary industry (commerce, government service, and service work); (5) of those in the labor force the ratio of unemployed in the exposed population seemed slightly higher, but due to the small number surveyed, statistical confirmation was not possible. Of those not in the labor force, no difference was noted according to exposure status; (6) in the sickness prevalence rate no difference could be observed between the exposed and nonexposed.

A lifelong journey of moving beyond wartime trauma for survivors from Hiroshima and Pearl Harbor.

2011-01-01

This study examines 51 stories of health, shared by people who survived the wartime trauma of Hiroshima and Pearl Harbor, seeking to identify turning points that moved participants along over their lifetime. The central turning point for Hiroshima survivors was "becoming Hibabusha (A-bomb survivor)" and for Pearl Harbor survivors was "honoring the memory and setting it aside." Wartime trauma was permanently integrated into survivors' histories, surfacing steadily over decades for Hiroshima survivors and intermittently over decades for Pearl Harbor survivors. Regardless of experience or nationality, participants moved through wartime trauma by connecting with others, pursuing personal and global peace.

Cytogenetic study of the offspring of atomic bomb survivors, Hiroshima and Nagasaki

Awa, A.A.; Honda, Takeo; Neriishi, Shotaro

1989-07-01

This paper describes the results of a cytogenetic study on 8,322 children born to atomic bomb survivors (4,716 in Hiroshima and 3,606 in Nagasaki) and 7,976 controls (5,112 in Hiroshima and 2,864 in Nagasaki). Because no child was examined before age 12, the data may not be considered valid for the occurrence of chromosomal abnormalities that impose a high risk of early death. Thus, we will restrict our comparison to the sex-chromosome aneuploids and autosomal structural rearrangements of the balanced type, although other abnormalities encountered in this survey will be enumerated. Among the children born to exposed parents, 19 individuals (0.23 %) exhibited sex chromosome abnormalities and 23 (0.28 %) exhibited autosomal structural rearrangements, whereas among children born to unexposed parents, 24 (0.30 %) and 27 (0.34 %), respectively, were observed to exhibit these abnormalities. Only one child with a karyotype of 47,XY,+21 was found in the Hiroshima exposed group. Thus, there was no statistically significant difference in the overall frequencies of cytogenetically abnormal cases between the exposed (0.52 %) and control (0.64 %) populations. In Hiroshima, frequencies of chromosome abnormalities were similar between exposed and control groups (0.64 % vs 0.65 %). However, the value observed in the exposed group in Nagasaki was slightly lower (0.36 %) - though not statistically significant - than the value observed in the control group (0.63 %). This value of the Nagasaki control group was similar to that in Hiroshima. Family studies on probands with chromosome abnormalities revealed that the majority of cases (about 90 %) with autosomal structural rearrangements of the balanced type were inherited from one or the other parent. The mutation rates for these reaarangements were similar between the exposed and control groups, being 0.98 x 10 -4 per gamete per generation. (author)

Decline of blood leukocyte counts 1947-59, Hiroshima and Nagasaki

Ichimaru, Michito; Ueda, Shoichi; Blaisdell, R K

1963-03-03

Earlier reports of progressive decline in leukocyte counts in Hiroshima from about 1948 to 1954 have been confirmed. A similar phenomenon has been observed in Nagasaki. Analysis indicates that this decline in white cell count with time is not related to exposure to the 1945 atomic bombs, to sex, to age, to commonly diagnosed diseases, or to the disproportionate influence of a subgroup. The principal white cells affected were neutrophils, lymphocytes and eosinophils. The precise etiologic factors accounting for the decline, and the biological significance of the present lower range of leukocyte values in Hiroshima and Nagasaki remain to be determined. 16 references, 5 figures, 5 tables.

The author shows that, in spite of uncertainties concerning dosimetry, scientists conducting research into radiopathology can still find their best data in the case histories of atomic bomb survivors. Using his original method he finds that the relations between dose and cancer risk have the same staged form at Hiroshima and Nagasaki and also after radiotherapy. The three-stage shift along the dose axis is easy to interpret. The recent modification proposed for dosimetry of bomb radiation only modifies the dose at each stage. This dose-risk correlation makes it possible for him to pinpoint the carcinogenic effect of supraliminal doses from this radiation with a retroactivity of over thirty years [fr

Studies have been completed on the activation of sulfur by fast neutrons from the Little Boy-Comet Critical Assembly which replicates the general features of the Hiroshima bomb. The complex effects of the bomb's design and construction on leakage of sulfur-activation neutrons were investigated both experimentally and theoretically. Our sulfur activation studies were performed as part of a larger program to provide benchmark data for testing of methods used in recent source-term calculations for the Hiroshima bomb. Source neutrons capable of activating sulfur play an important role in determining neutron doses in Hiroshima at a kilometer or more from the point of explosion. 37 refs., 5 figs., 6 tabs

Urinary findings of children exposed in utero to the atomic bombs, Hiroshima and Nagasaki

Energy Technology Data Exchange (ETDEWEB)

Freedman, L R; Keehn, R J

1966-06-09

Data from urinalyses at ages 9 to 16 were tabulated for children exposed to ionizing radiation in utero at the time of the atomic bombs in Hiroshima and Nagasaki in 1945 and for comparable control groups. Proteinuria was detected more often at various ages in boys in Hiroshima and girls in both cities whose mothers were within 1500 m of the bomb hypocenters. However, the differences were statistically significant only in girls ages 13 or 14. Casts were also seen more commonly in Hiroshima girls located at the same distance. Red and white blood cell excretion in the urine and glycosuria did not appear to be related to radiation exposure. Future investigations will be necessary to define the biological significance of these findings. 11 references, 8 tables.

For 63 years scientists in the Atomic Bomb Casualty Commission and its successor, the Radiation Effects Research Foundation, have been assessing the long-term health effects in the survivors of the atomic bombings of Hiroshima and Nagasaki and in their children. The identification and follow-up of a large population (approximately a total of 200 000, of whom more than 40% are alive today) that includes a broad range of ages and radiation exposure doses, and healthy representatives of both sexes; establishment of well-defined cohorts whose members have been studied longitudinally, including some with biennial health examinations and a high survivor participation rate; and careful reconstructions of individual radiation doses have resulted in reliable excess relative risk estimates for radiation-related health effects, including cancer and noncancer effects in humans, for the benefit of the survivors and for all humankind. This article reviews those risk estimates and summarizes what has been learned from this historic and unique study. PMID:21402804

Literature, cinema and history in "Hiroshima Mon Amour"

Directory of Open Access Journals (Sweden)

Nismária Alves David Barros

2013-06-01

Full Text Available This article analyzes Hiroshima Mon Amour, realization by Alain Resnais divulged in 1959 and ciné-roman by Marguerite Duras published in 1960. Considering the Jeanne-Marie Clerc's theory (2004, we understand that the literature and the cinema are resources of expression that do not establish competition or subordination relations, but they establish complementary relations, they make mutual exchanges for their renewals. They are not the documents on the atomic tragedy of Hiroshima because they congregate historical facts, literary narrative and cinematographic techniques. This ciné-roman and this film displays a revolutionary position of the artistic form to express a critical vision on the world after war. They create a love history and a history of loss, focusing the individual anguish in the plot. Through  the return to the past, using a poetical language, they discloses the pains of the protagonist and the pains of the humanity. Therefore the receiver reflects on himself.

Following the atomic bomb attacks on Japan in 1945, scientists from the United States and Japan joined together to study the Hibakusha - the bomb affected people in what was advertised as a bipartisan and cooperative effort. In reality, despite the best efforts of some very dedicated and earnest scientists, the early years of the collaboration were characterized by political friction, censorship, controversy, tension, hostility, and racism. The 70-year history, scientific output and cultural impact of the Atomic Bomb Casualty Commission and the Radiation Effects Research Foundation are described in the context of the development of Occupied Japan.

Activation of cobalt by neutrons from the Hiroshima bomb

Kerr, G.D.; Dyer, F.F.; Emery, J.F.; Pace, J.V. III; Brodzinski, R.L.; Marcum, J.

1990-02-01

A study has been completed of cobalt activation in samples from two new locations in Hiroshima. The samples consisted of a piece of steel from a bridge located at a distance of about 1300 m from the hypocenter and pieces of both steel and concrete from a building located at approximately 700 m. The concrete was analyzed to obtain information needed to calculate the cobalt activation in the two steel samples. Close agreement was found between calculated and measured values for cobalt activation of the steel sample from the building at 700 m. It was found, however, that the measured values for the bridge sample at 1300 m were approximately twice the calculated values. Thus, the new results confirm the existence of a systematic error in the transport calculations for neutrons from the Hiroshima bomb. 52 refs., 32 figs., 16 tabs

Studies on the health effects of a-bomb radiation exposure appeared in health examinations of adult survivors by the Radiation Effects Research Foundation

Yamada, Michiko

2006-01-01

The Research Foundation has conducted the health examinations in the title since 1958, based on which studies of a cohort type have been performed, and their results at present are summarized in this paper. Subjects have included a cohort of about 120000 cases in total. They have been those 4993 initial cases (the center group) exposed to estimated radiation doses of 4 -6 Gy within the distance of 2 km from the hypocenter and with acute exposure symptoms either in Hiroshima or Nagasaki, and 19961 cases (exposed ones within 2 km from the hypocenter but without the symptoms, exposed residents in the city 3 km far from the hypocenter, or ones absent in the city at explosion) matched to the above center group in the city, age and sex. Lower statures and weights are noted in some of the center group who were in growing ages at exposure. Increases of prevalence or incidence rate are suggested in malignant tumors, diseases of the thyroid and parathyroid, uterine myoma, chronic liver diseases, cataract, circulatory diseases, abnormal hemoglobin value, and psychological states. Relative risk at 1 Gy for incidence of non-cancer diseases is calculated and presented. Results are not always consistent with those of such population exposed to <6 Gy as that of Chernobyl Accident, of radiation technologist and of people accidentally exposed to environmental radiation. The Foundation is to continue the study and more profound results of radiation effects are expected to be obtainable. (T.I)

We looked at the radiation dose of Hiroshima and Nagasaki atomic bomb again in 1986. We gave it the name of ``Dosimetry System 1986`` (DS86). We and other groups have measured the expose dose since 1986. Now, the difference between data of {sup 152}Eu and the calculation result on the basis of DS86 was found. To investigate the reason, we carried out the calculations of neutron transport and neutron absorption gamma ray for Hiroshima atomic bomb by MCNP3A and MCNP4A code. The problems caused by fast neutron {sup 32}P from sulfur in insulator of pole. To correct the difference, we investigated many models and found agreement of all data within 1 km. (S.Y.)

Neutrons confirmed in Nagasaki and at the Army pulsed radiation Facility: Implications for Hiroshima

Recent reports have clearly demonstrated that large discrepancies exist between neutron activation measured in Hiroshima and activation calculated using the current dosimetry system DS86. The reports confirmed previous results for cobalt activation in Hiroshoma that suggested problems, and this has spurred a joint U.S.-Japan effort to identify the source(s) of this discrepancy. Here, new results are presented that appear to eliminate both the measurements of neutron activation and the DS86 air-transport calculations are potential sources of the discrepancy in Hiroshima. Computer transport of DS86 fission neutrons through large distances of air was validated using concrete samples from Nagasaki and chloride detectors placed at selected distances from a bare uranium reactor. In both cases accelerator mass spectrometry was used to measure thermal neutron activation via the reaction. 35 Cl(n, γ) 36 Cl (half-life, 301,000 years). Good agreement was observed between measurements of neutron activation and DS86 calculations for Nagasaki, as well as for the reactor experiment. Thus the large discrepancy observed in Hiroshima appears not to be due to uncertainties in air-transport calculations or in the activation measurements; rather, the discrepancy appears to be due to uncertainties associated with the Hiroshima bomb itself. 15 refs., 3 figs., 8 tabs

Small head size following in utero exposure to atomic radiation, Hiroshima and Nagasaki

Energy Technology Data Exchange (ETDEWEB)

Miller, R W; Blot, W J

1972-01-01

There was a progressive increase with dose in the frequency of abnormality among persons whose mothers were exposed before the 18th week of pregnancy. In Hiroshima the minimum dose producing an effect was 10 to 19 rad, but in Nagasaki no effect was observed under 150 rad. At maternal doses of > 150 rad, small head circumference was often accompanied by mental retardation. The low doses in Hiroshima are not directly applicable to medical radiology because of the presence of neutrons and environmental disturbances. (DLC)

Deterrence before Hiroshima

Energy Technology Data Exchange (ETDEWEB)

Quester, G.H.

1985-01-01

The gap between studies of military history and military strategy is ever widening. The enormous destructive power of nuclear weapons has tended to persuade us that the military experience of the first half of this century is not relevant to more ''modern'' military questions. In Deterrence before Hiroshima, first published in 1966, George H. Quester analyzes pre-nuclear age theories of deterrence to equip us with a perspective and data by which current theories can be evaluated. Quester shows that from almost the time of the first military aircraft, air-power was believed to have the capacity for apocalyptic destruction. He points out that the modern terms deterrence, limited war, tacit agreement, and balance of terror, show up often in the literature from 1900-1945, coupled with war scenarios every bit as awesome as a nuclear holocaust.

ABCC-NIH adult health study Hiroshima 1958 to 1959 thyroid disease

Energy Technology Data Exchange (ETDEWEB)

Hollingsworth, D R; Hamilton, H B; Tamagaki, Hideya; Beebe, G W

1962-04-01

In the matched sample for the Adult Health Study 5553 participants were examined in the ABCC clinic in Hiroshima, Japan during the sixteen month period from July 1958 through October 1959. Thyroid disease was diagnosed for 169 subjects, 152 of whom were female. Simple nontoxic goiter was the most frequently seen thyroid disorder comprising 47 percent of the total, with a sex ratio of 8 to 1 in favor of females. Hiroshima is a coastal city where iodine deficiencies seem unlikely and the various etiological possibilities responsible for nontoxic goiter were reviewed and discussed. Hyperthyroidism was observed in 16 patients of whom 13 were females. One patient with hypothyroidism and 5 with chronic thyroiditis diagnosed by biopsy were seen in the study. Single thyroid nodules were found in 39 patients; the biopsy diagnoses of 19 were listed, 8 of whom were shown to have thyroid carcinoma. Carcinoma of the thyroid was diagnosed microscopically in 12 patients, constituting 7 percent of the total number with thyroid disorders. It was concluded that thyroid disease in Hiroshima warrants further study and it will be of particular interest to carefully observe the Adult Health Study group for the incidence of thyroid nodules and thyroid carcinoma.

Sequelae of radiation facial epilation (North American Hiroshima maiden syndrome)

International Nuclear Information System (INIS)

Rosen, I.B.; Walfish, P.G.

1989-01-01

Radiation for benign problems of the head and neck area has been uniformly recognized as unacceptable practice. This includes epilation for facial hirsutism. Twelve such patients, recently encountered, have characteristic radiodermatitis facies and have demonstrated multisite neoplastic involvement--including skin, thyroid, parathyroid, salivary gland, oral cavity, facial skeleton, and breast--and have also undergone extensive dermatologic treatment of complications of radiodermatitis. There was one cancer death, and three patients are alive with cancer. Such patients have a superficial resemblance to the Hiroshima maiden group of young women who survived atomic bombing and experienced severe facial burns, necessitating extensive plastic surgery. As atomic survivors they are at increased risk for cancer of thyroid, salivary gland, lung, breast, bone marrow, and gastrointestinal tract. The North American Hiroshima maiden should warrant easy clinical recognition and require lifetime scrutiny for multisite neoplastic disease

Neoplasms among atomic bomb survivors in Hiroshima City. First report

Energy Technology Data Exchange (ETDEWEB)

Harada, Tomin; Ishida, Morihiro

1960-04-01

The 1957-1958 incidence of neoplasms among the survivors of the Hiroshima A-bomb, varies directly with radiation dose insofar as it may be inferred from distance from the hypocenter at exposure. The incidence of all malignant neoplasms among the survivors who were within 1000 meters is more than 4 times that of the non-exposed population. The incidence of benign neoplasms among the survivors exposed within 1500 meters is also significantly higher than that among the non-exposed. For survivors under 1500 meters significant differences are seen between the numbers of observed cancers of the lung, stomach, uterus and ovary and the expected cases calculated from the age-specific rates of the non-exposed portion of the Hiroshima population. The increased incidence among survivors within 1500 meters is not related to sex or age. 18 references, 2 figures, 14 tables.

Review of the radiological significance of revised dose estimates for the Hiroshima-Nagasaki bomb survivors

International Nuclear Information System (INIS)

Myers, D.K.; Osborne, R.V.

1988-03-01

Recently, the International Commission on Radiological Protection (ICRP) has indicated that new dosimetric and epidemiological data on Japanese bomb survivors will 'raise the risk estimate (for fatal cancers) for the exposed population by a total factor of the order of 2. This change is for a population of all ages, whereas for a worker population of ages 18-65 the changes will be small'. The present report has reviewed the available scientific literature that is relevant to this statement. The topics reviewed in this report include: a) the methods used in previous reports by scientific committees to calculate estimated lifetime risks of radiation-induced fatal cancers; b) recent revisions of the dosimetry for Hiroshima-Nagasaki survivors; c) updates on the epidemiological data on the Hiroshima-Nagasaki survivors; and d) revised estimates of fatal cancer risk from the Hiroshima-Nagasaki data

The Influence of the Climate Change on Landslide Disasters in Western Japan -Hiroshima's case-

Science.gov (United States)

Kubota, Tetsuya; Aditian, Aril

2015-04-01

In last year 2014 and 2012, tremendous landslides due to heavy rainfalls occurred in western Japan. Especially in August 2014, serious landslide disasters induced by the extremely heavy rainfall caused over 70 people's death in Hiroshima. Most of them were caused by debris flows from shallow landslides on granite forest slopes on August 20. In Hiroshima, long-term increase in rainfalls was not obvious, while this trend was found in other area such as Kyushu district. However, in western Japan, the influence of climate change emerged in the increase of vapor concentration caused by rising water surface temperature in East China Sea and that brought the extreme rainfall. The landslide (debris flow) disasters in Hiroshima have distinctive characteristics in terms of followings: (1) the source of debris flows (directly flowing down from mostly shallow landslides), (2) their usual equivalent friction coefficient "Mf" i.e. relative travel distance for Granite (values between 0.174 and 0.554). (3) the peculiar meteorological condition of frontogenesis with vapor convergence on the stationary front and around the Pacific high pressure that can generate the heavy precipitation (above 101 mm/hr, total 256 mm). (4) Contrary to Mf values above, they caused heavy disaster at downstream area with the urban development on hillside slopes. We found that the Mf becomes bigger (relatively short travel distance) as the return period of disasters"Tr"becomes shorter as evaluating in the next formula: Mf = 0.278 Tr^(-3.32). If the return period becomes shorter due to climate change (it is possible), Mf may become bigger. However, the cities such as Hiroshima, Kobe or Nagasaki in western Japan which have the urban area at hillside will be more prone to severe debris flow disasters. (5) Also, theoretically, we may have more slope failures and debris flows per area "N/A" if the rainfall increment "dR" increases. The "increasing ratio in N/A" is given by next equation: (N/A)/(N0/A)=((R0 + d

Trace analysis of irradiated steel samples from hiroshima by laser ablation inductively coupled plasma mass spectrometry

Helal, A.I.; Zahran, N.F.

2000-01-01

A double focusing (JEOL, PLASMAX2) and quadrupole (ELAN6000, Perkin Elmer) mass spectrometers were used for the quantitative analysis of trace elements in steel samples from Hiroshima. The quantification of the analytical results was carried out using steel 468 as a standard reference material. The relative sensitivity coefficients (RSC's) for most of the elements varied between 0.12 and 2.93. The effect of iron as a matrix and the non-spectroscopic interferences are studied. Comparison of the results obtained on two steel samples from Hiroshima with that obtained on steel 468 standard reference materials demonstrated that there is no significant difference between them. Therefore, it is possible to say that the irradiated steel samples from Hiroshima have nearly the same specifications of trace element content as those of the normal steel samples

Hiroshima and ourselves

International Nuclear Information System (INIS)

Lifton, R.J.

1985-01-01

The author discusses his feelings and responses which he experienced from interviewing Hiroshima survivors. As survivors attempted to recall their feelings at the time of the bomb, they conveyed a sense of having been immersed in a sea of death. They remembered not only the expectation of their own death but also the sense that the whole world was dying. What impressed the author most was the survivor's lifelong encounter with death, which could be understood as taking place in four stages: the immersion in death at the time of the bomb; the experience of acute radiation effects (including extreme weakness, severe gastrointestinal symptoms, bleeding into the skin and from bodily orifices, high fever, low white blood cell counts, alopecia, and death); delayed radiation effects (increased incidence of leukemia and of many forms of cancer); and an eventual sense of permanent death taint associated with the identity of hibakusha, or explosion-affected person

Estimation of the Hiroshima bomb yield and weather conditions at the time of the bomb

International Nuclear Information System (INIS)

Tajima, Eizo

1984-01-01

The results of the survey made immediately after the bombings in Hiroshima and Nagasaki were compiled in Collection of Reports on the Investigation of the Atomic Bomb Casualties published in 1953. Much valuable information for the reassessment of dose are included in this document. One of the major problems to be solved for the dose reassessment is the yield of the Hiroshima bomb. Two articles with relatively detailed description were selected, and the estimation of the yield was attempted, based on them. The data on roof tile melting were used for the purpose. Assuming the yield of the Nagasaki bomb as 22 kt, the yield of the Hiroshima bomb was given as 12.4 kt. By the experiment using the charred state of cypress boards, the total radiant energy from the bomb was calculated as 4.6 x 10 12 cal, and the yield of the Hiroshima bomb was estimated as 14.2 kt and 13.2 kt. The true value is likely between 12 and 13 kt. The vapor pressure at the time of bombing significantly affected the neutron spectrum. On the day of bombing, Japan was covered by hot, humid maritime air mass, namely summer monsoon pattern. The air density and water vapor content in the atmosphere were determined by the Japan Weather Association, and compared with the data of Dr. Kerr et al. (Kako, I.)

August 2014 Hiroshima landslide disaster and its societal impact

Science.gov (United States)

Fukuoka, Hiroshi; Sassa, Kyoji; Wang, Chunxiang

2015-04-01

In the early morning of August 20, 2014, Hiroshima city was hit by a number of debris flows along a linear rain band which caused extreme downpour. This disaster claimed 74 death, although this city experienced very similar disaster in 1999, claiming more than 30 residents lives. In the most severely affected debris flow torrent, more than 50 residents were killed. Most of the casualties arose in the wooden, vulnerable houses constructed in front of the exit of torrents. Points and lessons learnt from the disaster are as follows: 1. Extreme rainfall events : geology and geomorphology does not much affect the distribution of landslides initiation sites. 2. Area of causative extreme rainfall is localized in 2 km x 10 km along the rain band. 3. Authors collected two types of sands from the source scar of the initial debris slides which induced debris flows. Tested by the ring shear apparatus under pore-pressure control condition, clear "Sliding surface liquefaction" was confirmed for both samples even under small normal stress, representing the small thickness of the slides. These results shows even instant excess pore pressure could initiate the slides and trigger slide-induced debris flow by undrained loading onto the torrent deposits. 4. Apparently long-term land-use change affected the vulnerability of the community. Residential area had expanded into hill-slope (mountainous / semi-mountainous area) especially along the torrents. Those communities were developed on the past debris flow fan. 5. As the devastated area is very close to downtown of Hiroshima city, it gave gigantic societal impact to the Japanese citizens. After 1999 Hiroshima debris flow disaster, the Landslide disaster reduction law which intends to promote designation of landslide potential risk zones, was adopted in 2000. Immediately after 2014 disaster, national diet approved revision of the bill.

Epidemiological studies. From experience in Hiroshima and Nagasaki to Fukushima

International Nuclear Information System (INIS)

Okubo, Toshiteru

2011-01-01

Results of epidemiological studies by Radiation Effects Research Foundation (RERF) on A-bomb survivors in Hiroshima and Nagasaki over 60 years are described as they are conceivably useful for present health risk assessment, future measures and health problems in Fukushima. The studies conducted in the two Cities on total of about 120,000 people of survivors and unexposed control group have given following findings. Incidence of leukemia is increased several years after A-bomb exposure, and of diseases like thyroidal ones, cataract and solid cancers, at 10-20 years later. Individual dose assessment of these morbid people is established (DS02, Dosimetry published in 2003), which reveals the quantitative relationship between dose and incidence. This relationship is used as a reference to make up an international standard for protection of radiation hazard. Mean of excess relative risk (ERR) on linear non-threshold (LNT) hypothesis of solid cancers is around 0.4/Gy at age of 70 y for people exposed at age 30 y although there is a significant age and sex difference in ERR. As well as survivors, studies are performed on exposed fetuses and second generations from the exposed people, which show the increased incidence of newborn microcephaly from mothers exposed with high dose but overall health abnormality is not seen in offspring from exposed parents. Radiation exposure is mainly instantaneous in the two Cities and is mostly derived from neutron and gamma-ray, which are somehow different from that in Fukushima due to Nuclear Power Plant Accident. The latter involves long term external and internal exposures with alpha-, beta- and gamma-ray hereafter. The difference should be well recognized for risk assessment in Fukushima; exempli gratia (e.g.), at the same dose, instantaneous exposure is mentioned more risky than long term one. (T.T.)

Commemoration of the bombing of Hiroshima

On the occasion of 52 anniversary of bombing Hiroshima this speech is given by one if the survivors, stating that it is obvious that using nuclear weapons is the cruelest and most inexcusable crime in human history. It never should be used against anyone, for any purpose, anywhere. In the Statement of the Pugwash Council, in 1995, the theory of nuclear deterrence was clearly rejected. This certainly played a significant role in the award of 1995 Nobel Prize to Pugwash Conferences. The close of 20th century provides the best occasion to affirm the international political will to prohibit nuclear weapons

The present paper presents the 36 Cl measurement effort in the US. A large number of 36 Cl measurements have been made in both granite and concrete samples obtained from various locations and distances in Hiroshima and Nagasaki. These measurements employed accelerator mass spectrometry (AMS) to quantify the number of atoms of 36 Cl per atom of total Cl in the sample. Results from these measurements are presented here and discussed in the context of the DS02 dosimetry reevaluation effort for Hiroshima and Nagasaki atomic-bomb survivors. The production of 36 Cl by bomb neutrons in mineral samples from Hiroshima and Nagasaki was primarily via the reaction 35 Cl(n,γ) 36 Cl. This reaction has a substantial thermal neutron cross-section (43.6 b at 0.025 eV) and the product has a long half-life (301,000 y). hence, it is well suited for neutron-activation detection in Hiroshima and Nagasaki using AMS more than 50 years after the bombings. A less important reaction for bomb neutrons, 39 K(n,α) 36 Cl, typically produces less than 10% of the 36 Cl in mineral samples such as granite and concrete, which contain ∼ 2% potassium. In 1988, only a year after the publication of the DS86 final report (Roesch 1987), it was demonstrated experimentally that 36 Cl measured using AMS should be able to detect the thermal neutron fluences at the large distances most relevant to the A-bomb survivor dosimetry. Subsequent measurements in mineral samples from both Hiroshima and Nagasaki validated the experimental findings. The potential utility of 36 Cl as a thermal neutron detector in Hiroshima was first presented by Haberstock et al. who employed the Munich AMS facility to measure 36 Cl/Cl ratios in a gravestone from near the hypocenter. That work subsequently resulted in an expanded 36 Cl effort in Germany that paralleled the US work. More recently, there have also been 36 Cl measurements made by a Japanese group.

Physical Responses of Convective Heavy Rainfall to Future Warming Condition: Case Study of the Hiroshima Event

Directory of Open Access Journals (Sweden)

Kenshi Hibino

Full Text Available An extreme precipitation event happened at Hiroshima in 2014. Over 200 mm of total rainfall was observed on the night of August 19th, which caused floods and many landslides. The rainfall event was estimated to be a rare event happening once in approximately 30 years. The physical response of this event to the change of the future atmospheric condition, which includes a temperature increase on average and convective stability change, is investigated in the present study using a 27-member ensemble experiment and pseudo global warming downscaling method. The experiment is integrated using the Japan Meteorological Research Institute non-hydrostatic regional climate model. A very high-resolution horizontal grid, 500 m, is used to reproduce dense cumulonimbus cloud formation causing heavy rainfall in the model. The future climate condition determined by a higher greenhouse gas concentration is prescribed to the model, in which the surface air temperature globally averaged is 4 K warmer than that in the preindustrial era. The total amounts of precipitation around the Hiroshima area in the future experiments are closer to or slightly lower than in the current experiments in spite of the increase in water vapor due to the atmospheric warming. The effect of the water vapor increase on extreme precipitation is found to be canceled out by the suppression of convection due to the thermal stability enhancement. The fact that future extreme precipitation like the Hiroshima event is not intensified is in contrast to the well-known result that extreme rainfall tends to be intensified in the future. The results in the present study imply that the response of extreme precipitation to global warming differs for each rainfall phenomenon.

Genetic radiation effects of Hiroshima and Nagasaki atomic bombs

International Nuclear Information System (INIS)

Srsen, S.

1984-01-01

A group of researchers examined persons who had survived the Hiroshima and Nagasaki bombs and were irradiated and their progeny with the aim of getting an idea of the genetic effects of these explosions. Teratogenic effects are not discussed. In the lymphocytes of the peripheral blood of persons who had been exposed to high dose irradiation the researchers found a significant increase in chromosomal aberrations by conventional and more recent methods of chromosomal analysis. In parents who had survived the atomic holocaust there were no significant deviations as against the rest of the population in still births, neonatal defects, infant mortality, and mortality of first generation progeny, in neonate weight, the sex ratio, increased occurence of leukosis and chromosomal aberrations in their children. These negative findings in the first generation do not signify that there is no danger from atomic bomb blasts for human kind. They only indicate that the effects of radiation were to small to be found by routine methods or that the methods used were not suitable

Rhoades, W.A.; Barnes, J.M.; Santoro, R.T.

1994-01-01

A 1987 study of the radiation from the World War II nuclear weapons applied state-of-the-art data and computer techniques, providing an important advance in reliability of the results. Still, a disturbing disagreement remained between slow-neutron activation measurements and calculations for the Hiroshima event. Newer data have confirmed the validity of the discrepancy. This work examines various potential explanations. Of those examined, only an enhancement to the weapon neutron leakage spectrum in the vicinity of the 2.3 MeV oxygen cross section window can fit the data accurately

A 1.93 Ci (3.6 mg) californium-252 source was installed in the radiation facility of the Research Institute for Nuclear Medicine and Biology, Hiroshima University. This source produces fission neutrons (8.7 x 10 9 n/s at the time of its installation), which are similar to neutron spectrum of the atomic bombs. It is useful for studying biological effects of fission neutrons and neutron dosimetry. An apparatus was dosigned to accomodate this source and to apply it to such studies. It has resulted in profitable fission neutron exposures, while suppressing scattered neutrons and secondary gamma rays. This apparatus incorporates many safety systems, including one which interlocks with all of doors and an elevator serving the exposure room, so as to prevent accidents involving users. (author)

Leukemia in Hiroshima atomic bomb survivors from 1946 to 1975

International Nuclear Information System (INIS)

Ohkita, Takeshi

1976-01-01

In five recent years, 134 deaths from leukemia among Hiroshima citizen were recorded. Of these, 23 cases (17 acute and 6 chronic types) were atomic bomb survivors exposed within 2,000 m of the hypocenter. Fifteen of them (65%) were over 60 years of age. The frequency of chronic lymphocytic leukemia was still low. Although the risk of leukemia was greatly reduced after 1961, and the frequency of chronic granulocytic leukemia (one of the most characteristic type of Hiroshima atomic bomb-induced leukemia) was also decreased, the death rate from leukemia among survivors exposed within 2,000 m or 1,500 m from the hypocenter was about 3 to 4 times higher than the mean death rate in all Japan. Therefore, careful and long-range follow-up surveillance should be continued. A brief review was also made of relevant studies such as the influence of environmental and host factors in the epidemiology of leukemia, the incidence of leukemia in children exposed in utero, and leukemia in offspring of atomic bomb survivors.

1976-03-01

In order to study the differences in the incidence of a variety of disease (excluding tumors), between the cases exposed to the atomic bomb and those who were unexposed, main lesions were studied statistically by autopsy. The subjects were 1230 cases autopsied at the Hiroshima Atomic Bomb Hospital or the Hiroshima Red-Cross Hospital. They were divided into 318 cases exposed at a short distance from the bombed area (within 2 km), and 420 cases exposed at a long distance from that area (more than 2 km), including those who had come to Hiroshima later. Four hundred twenty nine unexposed cases were selected as controls. The incidence of tumor, disturbance of circulation, disturbance of the blood vessels in the brain, blood disease, and respiratory disease was higher in the exposed cases than in the unexposed cases. The incidence of cirrhosis of the liver was higher in females than in males, and was lower in cases farther from the bombed area. Cardiac infarction, valvular disease, and endocarditis were more often seen in the cases exposed near the bombed area. The incidence of the blood vessels in the brain was highest in the exposed cases near the bombed area. The incidence of disturbance of circulation, and disturbance of the blood vessels in the brain had a tendency to be higher in the exposed cases than in the unexposed cases. This is considered to be due to the advanced age in the exposed cases.

Content Analysis as a Foundation for Programmatic Research in Communication.

Slater, Michael D

2013-06-01

Previous arguments that content analyses provide the descriptive foundation for media effects research (McLeod & Reeves, 1980) are extended to include that content analyses can provide a sound and useful foundation for programmatic research by individual communication scientists. I discuss examples from my own work and from that of colleagues in communication and related disciplines. Use of messages sampled and coded in a content analysis in combination with survey data sets or as stimuli in experiments are highlighted. The particular potential for employing larger numbers of randomly sampled messages in experimental designs, and, with use of appropriate statistical methods, being able to generalize to populations of messages, is described.

Cultural humility: essential foundation for clinical researchers.

Science.gov (United States)

Yeager, Katherine A; Bauer-Wu, Susan

2013-11-01

Cultural humility is a process of self-reflection and discovery in order to build honest and trustworthy relationships. It offers promise for researchers to understand and eliminate health disparities, a continual and disturbing problem necessitating attention and action on many levels. This paper presents a discussion of the process of cultural humility and its important role in research to better understand the perspectives and context of the researcher and the research participant. We discern cultural humility from similar concepts, specifically cultural competence and reflexivity. We will also explore ways to cultivate cultural humility in the context of human subjects research. Mindfulness is one approach that can be helpful in enhancing awareness of self and others in this process. With a foundation in cultural humility, nurse researchers and other investigators can implement meaningful and ethical projects to better address health disparities. © 2013.

Suzuki, Misaki

2008-01-01

The trace amounts of elements in the sediments of sea bottom in Kii Channel, Hiroshima Bay and Tosa Bay were determined quantitatively by the neutron activation analysis. The following facts were illustrated particularly from the quantitative analysis of scandium, rare earths, thorium and uranium: 1) It was known from Ce/La ratio that the geological feature in the west part of Japan is reflected in Kii Channel, Hiroshima Bay and Tosa Bay; 2) The rare-earth element pattern and La/Lu ratio suggest the fact that Kii Channel, Hiroshima Bay and Tosa Bay are essentially composed of the materials of which origin is land; 3) From the fact that Ce/La ratio in these sites are slightly under 1.0, these sites are considered to be affected mainly by the materials of which origin is land; 4) The sedimentary environment in the marine bottom of the Japanese coasts has been found to be mostly under a reductive state.

Zeldis, L J; Jablon, S; Ishida, Morihiro

1963-01-01

Studies in Hiroshima and Nagasaki of a possible carcinogenic effect of radiation in survivors of the atomic bombings are included in programs conducted jointly by the Atomic Bomb Casualty Commission (ABCC) and the Japanese National Institute of Health (JNIH) with the collaboration of physicians and medical organizations in both cities. In order to cope with epidemiologic problems that attend these, in common with other studies of human populations, ABCC-JNIH programs are now oriented to the intensive surveillance of health, morbidity, and mortality principally in known, fixed cohorts of the survivors. The data reported here are derived from 3 interrelated programs in Hiroshima and Nagasaki: the JNIH-ABCC Life Span Study, Tumor Registry Studies, and Joint ABCC-JNIH Pathology Studies. The population samples utilized in these studies are defined along with summarizing pertinent information concerning their exposure to ionizing radiation.

Atomic bomb dosimetry for epidemiological studies of survivors in Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Maruyama, Takashi

1986-01-01

Better atomic bomb (A-bomb) radiation dose estimates with a higher accuracy are required for the epidemiological studies in Hiroshima and Nagasaki. Several scientists have tried to evaluate the free-in-air gamma ray and neutron dose and some weighting factors such as house shielding and body shielding. Since 1965, the tentative 1965 dose (T65D) has been widely used as the basic data for the dose determination of A-bomb survivors in epidemiological studies. In 1976, however, the reevaluation of the T65D dose was proposed by an American scientist who calculated the A-bomb doses on the basis of declassified data on the radiation spectra of the A-bomb. The development of computer technology made it possible to perform complicated dosecalculations for the Hiroshima and Nagasaki bombs. This paper describes the history of A-bomb dosimetry, reviews some issues in the determination of T65D, and discusses the necessity of reassessment of A-bomb dose and the expected values for survivors.

2007-09-01

This special issue of Journal of Physics: Condensed Matter comprises selected papers from the 1st International Conference on Quantum Simulators and Design (QSD2006) held in Hiroshima, Japan, 3-6 December 2006. This conference was organized under the auspices of the Development of New Quantum Simulators and Quantum Design Grant-in-Aid for Scientific Research on Priority Areas, Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT), and Hiroshima University Quantum design is a computational approach to the development of new materials with specified properties and functionalities. The basic ingredient is the use of quantum simulations to design a material that meets a given specification of properties and functionalities. For this to be successful, the quantum simulation should be highly reliable and be applicable to systems of realistic size. A central interest is, therefore, the development of new methods of quantum simulation and quantum design. This includes methods beyond the local density approximation of density functional theory (LDA), order-N methods, methods dealing with excitations and reactions, and so on, as well as the application of these methods to the design of new materials and devices. The field of quantum design has developed rapidly in the past few years and this conference provides an international forum for experimental and theoretical researchers to exchange ideas. A total of 183 delegates from 8 countries participated in the conference. There were 18 invited talks, 16 oral presentations and 100 posters. There were many new ideas and we foresee dramatic progress in the coming years. The 2nd International Conference on Quantum Simulators and Design will be held in Tokyo, Japan, 31 May-3 June 2008.

The impact of kidney foundations in alleviating the burden of CKD in India - an example, Tamilnad Kidney Research Foundation.

Chronic kidney disease (CKD) is a major public health problem in India. The CKD registry of India has been formed to understand the epidemiology of CKD in India. Due to health economics in India, the majority of CKD-affected patients cannot afford renal replacement therapy (RRT) services. There is an unmet need to improve the awareness of kidney disease in India, and the focus should be on prevention and early detection of CKD by screening high risk populations. The Tamilnad Kidney Research (TANKER) Foundation is a charitable trust established in 1993 with the aim to improve awareness and provide quality affordable treatment to underprivileged patients. TANKER is supported by contributions from well-wishers. It has three arms: i) treatment arm, ii) research arm, and iii) awareness and screening arm. TANKER Foundation offers free and subsidized dialysis twice weekly to 227 underprivileged patients. TANKER dialysis has been supported by state government funding schemes. TANKER actively supports and conducts research in nephrology. More than 100,000 people have benefitted from TANKER's kidney awareness programs. The screening programs have provided for early detection of CKD in both urban and rural areas. TANKER award functions are held annually to recognize research and exemplary service to society. The TANKER Foundation can be used as a model for developing countries to address the unmet needs in CKD management.

Contributing factors to long-term psychological consequences in Hiroshima A-bomb survivors

The atomic bombing in Hiroshima on August 6, 1945, caused an estimated casualty of 140,000 by the end of that year. Survivors faced hideous scenes and many lost family members. Later, in the early 1960s, increased rates of leukemia and other types of cancer were observed among the survivors. These long-term health effects caused serious apprehension to linger. However, only a few studies on psychological consequences among the survivors have been conducted. In 2008, Hiroshima City commissioned our study team to perform a large-scale survey on long-term health effects among the survivors. We delivered a questionnaire by mail to all subjects who were living in Hiroshima City and adjacent towns prior to the release of the A-bomb until the study was implemented. The number of potential subjects was 31,598 and the response rate was 75%. We analyzed a subsample of subjects (n=14,373) whose age at the event was 8 or above. In the multiple regression analysis, hibakusha (A-bomb victims) and those who were exposed to the Black Rain (fall-out) showed poor mental health compared to the comparison group on SF-8, K6 and IES-R scores even after adjusting socio-demographic variables. Although traumatic experiences at the event still affected mental health, anxiety for health effects and social stigma showed greater impact. Our findings suggest that even 63 years after the event, apprehension of health effects and social stigma harm mental health in A-bomb survivors. Our findings may also suggest that long-term risk communication will be vital to mitigate mental health effects among survivors of the Fukushima nuclear disaster. (author)

Pinkston, J.A.; Antoku, Shigetoshi; Russell, W.J.

1980-10-01

In the continuing evaluations of atomic bomb survivors for late radiation effects, not only doses from the A-bombs but those from other radiation sources must be considered, for the latter may be concomitantly acting factors causing bias among these investigations. In the present study, among 73 Hiroshima and 22 Nagasaki Adult Health Study (AHS) subjects who reported receiving radiation therapy, from 1970 through 1979, the medical records of 72 and 20, respectively, were reviewed, and 41 Hiroshima and 14 Nagasaki subjects were confirmed to have received radiation therapy. The data obtained in the present study were pooled with those of the previous investigation on radiation therapy exposures of AHS subjects prior to 1970. A total of 190 subjects have been documented as receiving radiation therapy and their doses were estimated. Energies used in treatments and diseases treated are discussed. Malignancies developed subsequent to radiation therapy in seven cases; five after treatment for malignancies and two after treatment for benign diseases. Neoplasms of 12 AHS subjects may have been induced by earlier radiation therapy; 5 in the earlier study and 7 in the present one. These investigations underscore the need for continued documentation of exposures to ionizing radiation for medical reasons, especially from sources incurring relatively high doses. Bias in assessments of late radiation effects among A-bomb survivors can thus be avoided. (author)

The Hydro Fellowship Program (program) began as an experiment to discover whether the hydropower industry could find mechanisms to attract new entrants through conducting relevant research to benefit the industry. This nationwide, new-to-the-world program was started through funding from the Wind and Water Power Technologies Office of the Energy Efficiency and Renewable Energy (EERE) Office of the Department of Energy (DOE). Between 2010-2015, the Hydro Research Foundation (HRF) designed and implemented a program to conduct valuable research and attract new entrants to the hydro workforce. This historic grant has empowered and engaged industry members from 25 organizations by working with 91 students and advisors at 24 universities in 19 states. The work funded answered pressing research needs in the fields of civil, mechanical, environmental, and electrical engineering, as well as law, energy engineering and materials innovation. In terms of number of individuals touched through funding, 148 individuals were supported by this work through direct research, mentorship, oversight of the work, partnerships and the day-to-day program administration. Based on the program results, it is clear that the funding achieved the hoped-for outcomes and has the capacity to draw universities into the orbit of hydropower and continue the conversation about industry research and development needs. The Foundation has fostered unique partnerships at the host universities and has continued to thrive with the support of the universities, advisors, industry and the DOE. The Foundation has demonstrated industry support through mentorships, partnerships, underwriting the costs and articulating the universities’ support through in-kind cost sharing. The Foundation recommends that future work be continued to nurture these graduate level programs using the initial work and improvements in the successor program, the Research Awards Program, while stimulating engagement of academia at the

The Adult Health Study population is composed of four exposure groups of equal size, matched by age and sex. Participation scores are analyzed with respect to exposure, age, sex, and socioeconomic variables as well as history of previous contact with the ABCC programs. Significant differences were demonstrated between the participation scores by age, marital status, history of prior contact with ABCC, and occupation; this latter category was significant only for males. Although differences were observed for these variables, the significance was usually attributable to one category in each of the variables, often the least populated, such as separated or divorced for marital status; and previous history unknown for prior ABCC contact. A trend was apparent with respect to exposure, with the lowest participation noted in the nonexposed and the highest participation in the exposed group with symptoms. Sex differences were not significant. Although relatively minor differences were demonstrated for some variables, the outstanding features of this program are the remarkable high participation scores. Only 9 percent of the population were in the so-called refusal category and over 80 percent of the living Adult Health Study population, including non-Hiroshima residents, were examined during the period considered by this report. 6 references, 1 figure, 9 tables.

Autopsy study of small cardiac scars in Japanese men who lived in Hiroshima, Japan and Honolulu, Hawaii

International Nuclear Information System (INIS)

Steer, A.; Lee, S.S.; Stemmermann, G.N.; Yamamoto, Tsutomu; Rhoads, G.G.

1978-10-01

Japanese men long resident in Honolulu, Hawaii have significantly more ischemic heart disease, but significantly fewer small cardiac scars than men in Hiroshima, Japan. These scars occur in three forms: 1) small scars in the mural myocardium which account for the difference in frequency of small lesions in the two cities, and are of uncertain etiology; 2) areas of diffuse fibrosis in the papillary muscles. These are equally frequent in the two cities, and are associated with advancing age and sclerosis of papillary muscle arteries; and 3) focal scars in the papillary muscles. These are more frequent in Honolulu than Hiroshima. They are healed infarcts due to ischemic heart disease and are associated with a severe degree of extramural coronary artery sclerosis. Small mural myocardial scars, when present, are usually found in multiple sites, and are not related to age at death or heart weight. They are more common in the presence of sclerosis of intramural small arteries, but this association does not explain their more frequent occurrence in Hiroshima. There is no evidence that they are related to A-bomb radiation exposure. (author)

Trichinella spiralis has been found in three species of mammals born in Hokkaido so it possibly infects other species in Japan, including man. Although examination of human diaphragms in a small series of 149 autopsies in Hiroshima and 37 autopsies in Nagasaki (by digestion, compression, and microscopic sections) failed to reveal any instance of trichinous infection, it is felt that the existence or absence of human trichinosis inJapan can be determined only by examination covering a larger series of autopsies, and performed in various parts of the country. 6 references.

Memory and Identity in the Emotive Map of Alain Resnais’ Hiroshima Mon Amour (1959

Directory of Open Access Journals (Sweden)

Jytte Holmqvist

2014-11-01

Full Text Available The focus of this article is Alain Resnais’ representation of collective and individual memory and identity in Hiroshima Mon Amour (1959. The film is based on Marguerite Duras’ script from 1958 and remains faithful to this original text. With partial reference to Giuliana Bruno’s views on imaginary cities and urban cartography, the screened urban space will here be read as an emotive map in which the individual love story between the protagonists unfolds against the backdrop of their almost equally intimate relationship with the historically abused city of Hiroshima. This, in Bruno’s words helps create an affective “map of love” (243 or a “body-city on a tender map” (242. The paper highlights the fluid relationship between the protagonists and their environment, as well as the semi-documentary aspects of a film that establishes an effective dialogue between past and present.

1983-01-01

The effects of the atomic bomb dropped on Hiroshima and Nagasaki in 1945 are described. Immediately after the bombing, Japanese civilian and military authorities mobilized an intense effort to provide help to the damaged cities and their inhabitants. At the same time, research was undertaken by the Japanese in an attempt to determine the nature of the effects of the bombs on the population. Some weeks later, the American armed services and the Manhattan District also organized an investigation of these effects. This memoir describes the early days of the American research effort, its integration with the Japanese program, and the development of a Joint Commission to study the effects of the bombing. After the first rapid survey, described in this paper, the effort was reorganized and continued under the sponsorship of the National Research Councils of America and Japan as the Atomic Bomb Casualty Commission

Groups of Japanese and American scientists, supported by international collaborators, have worked for many years to ensure the accuracy of the radiation dosimetry used in studies of health effects in the Japanese atomic bomb survivors. Reliable dosimetric models and systems are especially critical to epidemiologic studies of this population because of their importance in the development of worldwide radiation protection standards. While dosimetry systems, such as Dosimetry System 1986 (DS86) and Dosimetry System 2002 (DS02), have improved, the research groups that developed them were unable to propose or confirm an additional contribution by residual radiation to the survivor's total body dose. In recognition of the need for an up-to-date review of residual radiation exposures in Hiroshima and Nagasaki, a half-day technical session was held for reports on newer studies at the 59 th Annual HPS Meeting in 2014 in Baltimore, MD. A day-and-a-half workshop was also held to provide time for detailed discussion of the newer studies and to evaluate their potential use in clarifying the residual radiation exposure to atomic bomb survivors at Hiroshima and Nagasaki. The process also involved a re-examination of very early surveys of radioisotope emissions from ground surfaces at Hiroshima and Nagasaki and early reports of health effects. New insights were reported on the potential contribution to residual radiation from neutron-activated radionuclides in the airburst's dust stem and pedestal and in unlofted soil, as well as from fission products and weapon debris from the nuclear cloud. However, disparate views remain concerning the actual residual radiation doses received by the atomic bomb survivors at different distances from the hypocenter. The workshop discussion indicated that measurements made using thermal luminescence and optically stimulated luminescence, like earlier measurements, especially in very thin layers of the samples, could be expanded to detect possible

To examine the radiogenic risk of latent thyroid cancer, thyroid adenoma, colloid/adenomatous goiter and chronic thyroiditis, the date for 3821 subjects collected in the course of autopsies of atomic bomb survivors in Hiroshima from 1951 to 1985 by the Radiation Effects Research Foundation (RERF) were analyzed using a logistic model. About 80% of the autopsies were performed at RERF and the remainder at local hospitals. The frequencies of the above diseases were not associated with whether the underlying cause of death was cancer. However, note that our results may be influenced by potentially biasing factors associated with autopsy selection. The relative frequency of latent thyroid cancer (greatest dimension ≤1.5 cm but detectable on a routine microscopic slide of the thyroid gland) increased as the radiation dose increased and was about 1.4-fold greater at 1 Gy than in the 0-Gy dose group. The relative occurrence of thyroid adenoma also increased as radiation dose increased, and was about 1.5-fold greater at 1 Gy than in the 0-Gy dose group. Sex, age at the time of the bombing or period of observation did not significantly modify the radiogenic risks for thyroid adenoma or latent thyroid cancer. No statistically significant association was found between radiation exposure and the rates of colloid/adenomatous goiter and chronic thyroiditis. The possible late effect of atomic bomb radiation on the frequency of benign thyroid diseases is discussed on the basis of these data. 38 refs., 2 figs., 5 tabs

Hiroshima to Fukushima biohazards of radiation

CERN Document Server

Ochiai, Eiichiro

2014-01-01

Set against a backdrop of the recent disaster at the Fukushima nuclear power plant, "Hiroshima to Fukushima" examines the issue of radiation safety. The author provides important and accurate scientific information about the radioactive substances arising from nuclear power plants and weapons, including the effects of this radiation on living organisms. Currently, humankind is at a crossroads and must decide whether to phase out or increase its reliance on nuclear power as weapons and an energy source. Although a few countries, mostly European, have vowed to abolish nuclear power as an energy source, many other countries are about to increase their nuclear power programs. This book is written from a Japanese perspective and thus provides an alternative to views of Western writers. The author includes rigorous scientific analyses, however maintains a broad scope which allows the book to be accessible to decision-makers and non-specialists.

Full Text Available When nine million foreigners visited Japan in 2013, the federal government set a goal to attract an additional two and a half million visitors including medical tourists by 2020. This research investigates the attitudes and concerns of Japanese nurses when they are in a situation dealing with foreign patients. The data were collected from March through September 2010, from 114 nurses at three hospitals, in close proximity to popular tourist destinations in Hiroshima. A questionnaire was developed for this research, named Mari Meter, which included a section to write answers to an open question for the nurses to express their opinions. These responses were examined statistically and by word analysis using Text Mining Studio. Japanese nurses expressed greatest concern about payment options, foreign language skills, and issues of informed consent, when dealing with foreigners. The results confirm that, in order to provide a high quality of patient care, extra preparation and a greater knowledge of international workers and visitors are required by nursing professionals in Japan.

Summary of the studies at ABCC-RERF concerning the late hematologic effects of atomic bomb exposure in Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Finch, S.C.; Finch, C.A.

1990-06-01

The most significant late hematologic effect of atomic bomb radiation exposure in the populations of Hiroshima and Nagasaki has been the increased occurrence of leukemia. The radiation effect for leukemia has disappeared in Nagasaki but slightly elevated rates still exist in Hiroshima. Multiple myeloma also is radiation-related, but there is only a suggestive relationship for malignant lymphoma. No evidence exists of a late radiation effect for primary disturbances of hematopoiesis in the absence of malignant disease. Somatic hematopoietic markers of previous radiation exposure include lymphocyte chromosomal aberrations and an increased frequency of mutant T-lymphocytes deficient in hypoxanthine phosphoribosyltransferase. A radiation effect also has been observed for the frequency of mutant erythrocytes lacking expression of glycophorin-A protein on the membrane. There is no evidence for radiation-induced disturbance of granulocyte function, but age-related accelerated decline in the immunological functions of T lymphocytes and age-related alteration in the number of certain subsets of circulating T and B lymphocytes appears to be radiation-related. A number of radiation-related hematology research proposals which might be considered for the future are included in this report. (author) 92 refs

This report summarizes the present state of knowledge in dosimetry of the Hiroshima-Nagasaki A-bomb survivors. Data have been presented on the physical factors involved in the two cities and on attenuation of radiation by various shielding situations. This information is being used to estimate a tentative radiation dose to individual A-bomb survivors. It should be emphasized that many important problems remain to be solved before accurate doses can be assigned to individual survivors. Such information will greatly strengthen investigation of biological consequences of instantaneous doses of gamma and neutron irradiation in men. 18 references, 9 figures.

Commemorating the fiftieth anniversary of Hiroshima, this paper covers three issues: Personal experience, concluding that the bomb was an extraordinary cruel weapon beyond imagination, Japanese experience, i.e. Japanese attitude against nuclear weapons and the actions to be undertaken in order to achieve nuclear-weapon-free world. The support of Non-proliferation Treaty, as well as the support of the protest against any kind of nuclear weapon experiments should be related to the understanding of the cause of the events against which one is protesting. The radical therapy would be the removal of the cause, i.e. the striking discrepancy of nuclear armaments

The National Athletic Trainers' Association (NATA) Research & Education Foundation offers a Research Mentor Program to provide mentorship to promising investigators, particularly as they work to establish independent lines of research.   To gain the perspectives of promising and established investigators on their participation in the NATA Foundation Research Mentor Program.   Qualitative, phenomenological research.   Higher education institutions.   Seven promising investigators (5 women, 2 men) and 7 established investigators (2 women, 5 men), all of whom had completed the NATA Foundation Research Mentor Program. Data Collection and Analysis We developed and piloted intervi: ew guides designed to gain participants' perspectives on their experiences participating in the NATA Foundation Research Mentor Program. Semistructured telephone interviews were completed with each individual and transcribed verbatim. Data were analyzed using a phenomenological approach, and saturation was obtained. Trustworthiness was established with the use of member checking, multiple-analyst triangulation, and data-source triangulation.   Three themes emerged from the interviews: (1) motivation, (2) collaboration, and (3) resources. Participants were motivated to become involved because they saw the value of mentorship, and mentees desired guidance in their research. Participants believed that collaboration on a project contributed to a positive relationship, and they also desired additional program and professional resources to support novice faculty.   Promising and established investigators should be encouraged to engage in mentoring relationships to facilitate mentees' research agendas and professional development. The NATA Foundation and athletic training profession may consider providing additional resources for novice faculty, such as training on

INSTRUMENTS OF SUPPORT FOR RESEARCH AND DEVELOPMENT FUNDED BY LEADING DOMESTIC AND INTERNATIONAL SCIENCE FOUNDATIONS

Full Text Available Introduction: one of the key aspects of the knowledge economy development is the growing significance of the results of research and development. The education and basic research play a key role in this process. Funding for education and fundamental science is carried out mainly at the expense of the state resources, including a system of foundations for scientific, engineering and innovation activities in Russia. The purpose of this article is to present recommendations for improving the tools of domestic foundations in funding fundamental research and development, including education and training. The propositions are made with a comparative analysis of the domestic and foreign science foun dations’ activities. Materials and Methods: the authors used analysis, comparison, induction, deduction, graphical analysis, generalisation and other scientific methods during the study. Results: the lack of comparability between domestic and foreign scientific funds in the volume of funding allocated for basic research and development is revealed. This situation affects the scientific research. The foreign foundations have a wide range of instruments to support research projects at all stages of the life cycle of grants for education and training prior to release of an innovative product to market (the use of “innovation elevator” system. The Russian national scientific foundations have no such possibilities. The authors guess that the Russian organisations ignore some of the instruments for supporting research and development. Use of these tools could enhance the effectiveness of research projects. According to the study of domestic and foreign experience in supporting research and development, the authors proposed a matrix composed of instruments for support in the fields of basic scientific researches and education with such phases of the project life cycle as “research” and “development”.

These uncertainties in the FIA kerma include contributions due to various modeling parameters and the basic cross section data and are given at three ground ranges, 700, 1000 and 1500 m. The estimated uncertainties are nearly constant over the given ground ranges and are approximately 27% for the prompt neutron kerma and secondary gamma kerma and 35% for the prompt gamma kerma. The total kerma uncertainty is dominated by the secondary gamma kerma uncertainties which are in turn largely due to the modeling parameter uncertainties

The new radiation dosimetry for the A-bombs in Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Kerr, G.D.

1988-01-01

Extensive work has been conducted over the past few years to reassess all aspects of the radiation dosimetry for the A-bombs in Hiroshima and Nagasaki. This work has included reviews of the bomb yields, source terms, air transport of neutrons and gamma rays, neutron-induced radioactivity and thermoluminescence in exposed materials, shielding of individuals by buildings, and calculations of organ doses. The results of these theoretical and experimental activities have led to the development of a new dosimetry system which is designated as the Dosimetry System 1986 (DS86). New DS86 estimates of tissue kerma in air and absorbed dose to fifteen organs are available for 94,787 survivors who were either outside and unshielded, outside and shielded by houses, or inside and shielded by houses (64,408 in Hiroshima and 30,379 in Nagasaki). The organ doses are calculated on an age-dependent basis as follows: infants (less than 3 years old at the time of bombing, ATB), children (3 to 12 years old ATB), and adults (more than 12 years old ATB). Work in progress includes the extension of the DS86 system to Nagasaki survivors who were shielded either by terrain or by factory buildings

ABCC-NIH Adult Health Study, Hiroshima, 1959: achlorhydria

Energy Technology Data Exchange (ETDEWEB)

Knittle, J L

1960-07-12

In Hiroshima Adult Health Study 1251 subjects were examined for achlorhydria and the proportion with achlorhydria was analyzed as to age, sex, blood type, and exposure to radiation. Achlorhydria was found to be more prevalent in subjects aged 40 and over,than in similar United States populations, and blood Type A subjects were found more achlorhydric than Type O subjects at ages 30 to 49. No differences were found between exposed and nonexposed, nor between those exposed at greater and lesser distances from the hypocenter. The data suggest that achlorhydria may be related to the high incidence of gastric cancer in Japan and seem consistent with the hypothesis that achlorhydria occurs prior to gastric cancer and may be related to inherited factors. 26 references, 4 tables.

Estimate of person-years at risk among A-bomb survivors, Hiroshima and Nagasaki

1964-11-19

Using information from the Supplementary Schedules of the 1950 National Census and from the JNIH-ABCC Life Span Study, cumulative person-years at risk in 1950 to 1960 were estimated by age ATB, sex, distance from hypocenter, radiation dose and symptoms for A-bomb survivors resident in Hiroshima and Nagasaki cities. The number of person-years at risk in 1951 to 1958 was estimated by applying the survivorship in each age group of the Adult Health Study sample during the period 1951 to 1958 to the number of survivors in 1950. To determine the number of person-years at risk from 1959 to 1960, the average yearly loss was evaluated for each exposure group for the period 1955 to 1958 in Hiroshima and for 1953 to 1958 in Nagasaki which was then applied to 1959 and 1960, respectively. The estimate of person-years among the nonexposed groups for this period was obtained from the above estimates, the total population of both cities, and the number of persons born after the A-bombing. Estimates by other associated factors were obtained by the same procedure. 20 references, 25 tables.

Taking stock of the ethical foundations of international health research: pragmatic lessons from the IU-Moi Academic Research Ethics Partnership.

Science.gov (United States)

Meslin, Eric M; Were, Edwin; Ayuku, David

2013-09-01

It is a sine qua non that research and health care provided in international settings raise profound ethical questions when different cultural and political values are implicated. Yet ironically, as international health research expands and as research on ethical issues in international health research broadens and deepens, we appear to have moved away from discussing the moral foundations of these activities. For international health research to thrive and lead to the kind of benefits it is capable of, it is helpful to occasionally revisit the foundational premises that justify the enterprise as a whole. We draw on the experience of the Indiana University-Moi University Academic Research Ethics Partnership, an innovative bioethics training program co-located in Indianapolis and Eldoret, Kenya to highlight the changing nature of ethical issues in international health research and the ongoing practical challenges.

Action taken by three humans, an American physicist in the bomber, two Japanese with radiation poisoning in Hiroshima and Nagasaki when the atomic bombs were exploded

Luis W. Alvarez of the Lawrence Berkeley National Laboratory (LBNL), University of California, USA, won the Nobel Prize for physics of elementary particle in 1968. He was very famous physicist and concerned the World War II in some ways. He joined the radar research development at MIT Radiation Lab. in 1940, then he developed the magnetron and the ground-controlled approach (GCA) for blind landing of planes. Afterwards he joined the Manhattan Project to fabricate the atomic bombs. His career connecting to those is introduced partly based on his autobiography. In addition, introduced are two reports by two Japanese, the personal experience of Yoko Ota with radiation poisoning in Hiroshima, and the action of Takashi Nagai who assisted the victims of radiation poisoning in Nagasaki even if he had radiation poisoning himself, as well as a letter from Luis W. Alvarez to Ryokichi Sagane, which was put in the tube of atomic bomb energy measuring instruments. Nightmares of the Hiroshima view are also introduced. (S.Y.)

The third medical examination of A-bomb survivors residing in the U.S. was performed in San Francisco, Los Angeles, Seattle and Honolulu during the period 6 - 28 May 1981. The test results were studied and the actual state of the survivors in the U.S., was reviewed as explained hereunder. 1) The number of survivors actually registered with the Committee of A-bomb Survivors in the U.S. is 491 (133 males and 358 females) of whom 57.2% are U.S. citizens. Those exposed in Hiroshima accounted for 91.8%. The mean age was 53.3 +- 8.9, thus they were more than 3 years younger than their counterparts in Hiroshima. The present addresses of the survivors are distributed over 15 states, but those in California constitute 77.6% of the total, and when those residing in the states along the west coast and Hawaii are added the rate increases to 95.9%. 2) Those who underwent health examination numbered 166 (45 males and 121 females), and comparison of the U.S. survivors against the Hiroshima survivors showed there to be a difference in the following points. The prevalence of hypertension was lower among the U.S. survivors, but RBC counts and hemoglobin concentration were significantly higher. The same was observed for blood lipids with hypercholesterolemia and hypertriglyceridemia being found at a significantly higher rate in the U.S. survivors. 3) Those free of clinical abnormalities in this survey were 37.3%, and the rest required dietary guidance, follow-up observation, detailed examination of treatment. Those with diseases which are considered would make them eligible for health management allowance if in Japan, accounted for 18.7%. (author)

Serum immunoglobulins (SI) were determined in 803 survivors and matched controls. Each subject's age, sex, health, exposure, and medical record were evaluated with respect to serum IgG, IgA, IgM levels. The IgG and IgA levels tended to be higher for this Hiroshima population than for Americans. Past exposure to ionizing radiation showed no significant correlation to SI levels. However, age and sex did influence the SI. IgM was significantly higher in females. With advancing age IgG and IgA increased in males, and IgM decreased in females. Elevated sedimentation rate and increased lymphocytes were accompanied by increased SI levels. Radiographic TB was detected in 45% of the population; IgG and IgA levels were somewhat elevated in these individuals. (DLC)

Hiroshima to Fukushima. Biohazards of radiation

Energy Technology Data Exchange (ETDEWEB)

Ochiai, Eiichiro

2014-04-01

Examines the issue of nuclear energy and nuclear weapons for a wide audience. Written from a Japanese perspective. Discusses one of the most important policy issues of the 21st Century. Set against a backdrop of the recent disaster at the Fukushima nuclear power plant, ''Hiroshima to Fukushima'' examines the issue of radiation safety. The author provides important and accurate scientific information about the radioactive substances arising from nuclear power plants and weapons, including the effects of this radiation on living organisms. Currently, humankind is at a crossroads and must decide whether to phase out or increase its reliance on nuclear power as weapons and an energy source. Although a few countries, mostly European, have vowed to abolish nuclear power as an energy source, many other countries are about to increase their nuclear power programs. This book is written from a Japanese perspective and thus provides an alternative to views of Western writers. The author includes rigorous scientific analyses, however maintains a broad scope which allows the book to be accessible to decision-makers and non-specialists.

Statement by IAEA Director General on the 60th anniversary of the atomic bombing of Hiroshima and Nagasaki

International Nuclear Information System (INIS)

2005-01-01

Full text: No one who has seen the victims, the film footage or photographs of the aftermath of the destruction of Hiroshima and Nagasaki at the end of World War II can fail to be horrified by the devastation that was wrought by the use of nuclear weapons. To date, Hiroshima and Nagasaki thankfully remain the only instances in which nuclear weapons have been used, and while it is difficult to speak of any good coming out of such ruin, it has always been hoped that the atomic bombing of Hiroshima and Nagasaki stand as constant reminders of why preventing the further use and proliferation of such weapons - and why nuclear disarmament leading to a nuclear-weapon-free world - is of utmost importance for the survival of humankind and planet Earth. The International Atomic Energy Agency born out of President Eisenhower's 'Atoms for Peace' vision, came at a time when the horrifying consequences and images of Hiroshima and Nagasaki were still fresh. Through its safeguards and verification system in support of the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and other similar non-proliferation agreements, the IAEA has done a great deal of work to help stem the tide of nuclear proliferation, while ensuring that the benefits of the peaceful uses of nuclear energy are made available to all those who want them. While the Agency can effectively verify compliance with non-proliferation undertakings, the value of these efforts can be better realized if they are reinforced by all other components of the nuclear non-proliferation and arms control regime, and accompanied by the political will and dialogue among concerned States to address underlying issues of security and confidence building with a view to achieving a system of collective security that no longer relies on nuclear weapons. A world without nuclear weapons remains a far-off goal and the world continues to be burdened with nearly thirty thousand nuclear warheads. The Comprehensive Nuclear-Test-Ban Treaty

An autopsy study of cerebrovascular disease in Japanese men who lived in Hiroshima, Japan and Honolulu, Hawaii

International Nuclear Information System (INIS)

Mitsuyama, Yoshio; Thompson, L.R.; Hayashi, Takuji; Lee, K.K.; Keehn, R.J.

1979-01-01

Evidence of cerebrovascular disease at autopsy was compared in two groups of men, 186 long time residents of Hiroshima, Japan and 253 men of Japanese ancestry long resident in Honolulu, Hawaii. They were from 45 to 71 years of age at death. Atherosclerosis of the circle of Willis and its major branches, sclerosis of the intraparenchymal arteries and the frequency of cerebral hemorrhage and cerebral infarct were compared in the two populations. The Honolulu subjects had significantly more atherosclerosis of the circle of Willis, but less intraparenchymal artery sclerosis and less cerebral infarction. Cerebral hemorrhage was equally frequent in the two cities. It was concluded that cerebral infarction is more frequent in Japanese men in Hiroshima than Honolulu, and that men of Japanese ancestry in Honolulu are spared an appreciable risk of cerebral infarction through decreased frequency of intraparenchymal arterial sclerosis despite higher levels of atherosclerosis of large intracranial arteries.

Full Text Available High-throughput scientific instruments are generating massive amounts of data. Today, one of the main challenges faced by researchers is to make the best use of the world’s growing wealth of data. Data (reusability is becoming a distinct characteristic of modern scientific practice. By data (reusability, we mean the ease of using data for legitimate scientific research by one or more communities of research (consumer communities that is produced by other communities of research (producer communities. Data (reusability allows the reanalysis of evidence, reproduction and verification of results, minimizing duplication of effort, and building on the work of others. It has four main dimensions: policy, legal, economic and technological. The paper addresses the technological dimension of data reusability. The conceptual foundations of data reuse as well as the barriers that hamper data reuse are presented and discussed. The data publication process is proposed as a bridge between the data author and user and the relevant technologies enabling this process are presented.

Hematologic studies of irradiated survivors in Hiroshima, Japan. Refractory anemia occurring in survivors of the atomic bombing in Nagasaki, Japan

Energy Technology Data Exchange (ETDEWEB)

Yamasowa, Yoshimichi; Lange, R D; Wright, S W; Tomonaga, Masanobu; Kurasaki, Hirotami; Matsuoka, Shigeru; Matsunaga, Haruji

1959-01-01

This document contains 2 reports on the effects of radiation on the survivors of the atomic explosions in Hiroshima and Nagasaki. The first report is a hematologic survey conducted 33 to 44 months after the detonation of the atomic bomb in Hiroshima, Japan. The hematologic findings on a total of 824 survivors are compared with those on a control group of 1145 residents of Kure. Although statistical differences are apparent in the two groups, when one takes into account errors inherent in the hematologic methods themselves and differences in the possible incidence of parasitism and nutrition it would be unwarranted to attribute the slight changes found to radiation effect. The data presented here seem to indicate that radiation resulting from the explosion of the atomic bomb in Hiroshima, on August 6, 1945, has not significantly varied the hematologic values as analyzed in this report over a three-to four-year period. In the second report, the case histories of six Nagasaki atomic bomb survivors who developed refractory anemia are presented. Four of these individuals received undoubted radiation injury. The fact that refractory anemia may occur as a late manifestation of exposure to atomic radiation is pointed out. 15 references, 5 figures, 2 tables.

ABCC-JNIH Adult Health Study, Hiroshima 1958-1960. Cardiovascular Project Report 3. Prevalence of cardiovascular diseases related to associated factors

1962-12-12

A long-term follow-up investigation of cardiovascular disease was organized primarily as an intensive substudy of the ABCC-JNIH Adult Health Study and secondarily for epidemiologic comparison with data on the Framingham, Massachusetts, population. One of the purposes of the present cardiovascular studies on a Hiroshima population was to obtain data comparable with that of the Framingham Study. An equally important aspect of the Hiroshima study is to explore radiation effects on the cardiovascular system. The sample is the Adult Health Study population and consists of 13,000 males and females in Hiroshima. This report provides the prevalence of cardiovascular disease in the first cross-section examined during 1958-1960 together with certain information on related factors. The overall attrition rate was 25%; 15% was caused by death or migration before the examination and 10% by refusal to participate. No significant difference was found in the blood pressure levels between the nonrespondents and the respondents in comparison with results of prior examinations at ABCC. The prevalence of various cardiovascular diseases was analyzed by sex and age. The analysis also extended to relationship of blood pressure, serum cholesterol, body weight, heart size, and occupation, with the prevalence of coronary heart disease for the sample over 40 years of age. 12 references, 15 tables.

Overview of the RERF scientific research program

International Nuclear Information System (INIS)

Bennett, B.G.

2003-01-01

Radiation Effects Research Foundation (RERF) was founded to study the effects of radiation in survivors of the atomic bombings of Hiroshima and Nagasaki. Several fixed cohorts or sub-cohorts were established to provide epidemiological and clinical data on the health status and mortality of survivors and their children. Genetics and radiobiological studies are carried out to help interpret the findings. The Life Span Study is the core project of RERF. It consists of a large cohort from a general population of both sexes and all ages, encompassing a wide range of accurately known doses and incorporating accurate disease incidence and mortality recording. These features make this a very valuable and informative study. The Adult Health Study is a clinical study of a sub-cohort of the Life Span Study. Examinations of survivors are conducted every two years, providing a continuing health profile of an aging population and establishing the radiation-related risk of non-cancer diseases. The children of atomic-bomb survivors are being studied to determine whether genetic effects might be apparent that could be related to parental exposures. Initial study of post-natal defects did not demonstrate discernable effects. The mortality follow up is continuing. A new clinical study of survivor children was recently started to examine the health condition of these now middle-aged individuals. It is now 58 years since the atomic bombings of Hiroshima and Nagasaki. The legacy of those events still marks the lives of the survivors. RERF feels an important responsibility to investigate the effects of radiation to contribute to the welfare of those affected, to understand and quantify the effects, and to provide a scientific basis for radiation protection worldwide. We intend to continue a high quality scientific research program into the future, establishing where possible more collaborative efforts to be sure that our shared resources and capabilities are most effectively utilized

Rediscovery of an old article reporting that the area around the epicenter in Hiroshima was heavily contaminated with residual radiation, indicating that exposure doses of A-bomb survivors were largely underestimated.

Science.gov (United States)

Sutou, Shizuyo

2017-09-01

The A-bomb blast released a huge amount of energy: thermal radiation (35%), blast energy (50%), and nuclear radiation (15%). Of the 15%, 5% was initial radiation released within 30 s and 10% was residual radiation, the majority of which was fallout. Exposure doses of hibakusha (A-bomb survivors) were estimated solely on the basis of the initial radiation. The effects of the residual radiation on hibakusha have been considered controversial; some groups assert that the residual radiation was negligible, but others refute that assertion. I recently discovered a six-decade-old article written in Japanese by a medical doctor, Gensaku Obo, from Hiroshima City. This article clearly indicates that the area around the epicenter in Hiroshima was heavily contaminated with residual radiation. It reports that non-hibakusha who entered Hiroshima soon after the blast suffered from severe acute radiation sickness, including burns, external injuries, fever, diarrhea, skin bleeding, sore throat and loss of hair-as if they were real hibakusha. This means that (i) some of those who entered Hiroshima in the early days after the blast could be regarded as indirect hibakusha; (ii) 'in-the-city-control' people in the Life Span Study (LSS) must have been irradiated more or less from residual radiation and could not function properly as the negative control; (iii) exposure doses of hibakusha were largely underestimated; and (iv) cancer risk in the LSS was largely overestimated. Obo's article is very important to understand the health effects of A-bombs so that the essence of it is translated from Japanese to English with the permission of the publisher. © The Author 2017.

This research project also aims to build foundations on how to implement future interventions to guide music students on how to optimize practice toward performance. A two-month psychological skills intervention was provided to two students from the national music academy’s bachelor program in music performance to better understand how to adapt and construct psychological skills training programs for performing music students. The program evaluated multiple intervention tools including the use of questionnaires, performance profiling, iPads, electronic practice logs, recording the perceived value of individual and combined work, as well as the effectiveness of different communication forms. Perceived effects of the intervention were collected through semi-structured interviews, observations, and logs.

In exploding an atomic bomb, in addition to ionizing radiation, strong non-ionizing radiation, such as infrared, ultraviolet light, visible light, electromagnetic pulse radiation, as well as heat and shock waves are produced. The survivors and those who visited Hiroshima immediately after the atomic bombing could have been subjected to a number of other possible noxious effects in addition to atomic radiation. Hospitals, laboratories, drugstores, pharmaceutical works, storehouses of chemicals, factories, etc. that were situated close to the hypocenter were all completely destroyed and various mutagenic, carcinogenic or teratogenic substances must have been released, many doctors, nurses and chemists were killed. There was no medical care and no food in the region of high dose exposure and the drinking water was contaminated. There would have been various possibilities of infection. Mental stress would also have been much higher in the survivors closer to the hypocenter. It is confusing which factor played a dominant role. In addition, there would be problems in accurately identifying the position of the exposed persons at the time of the atomic bombing and also in estimating the shielding factors. There may be considerable uncertainty in human memory under such conditions. It is also possible that there could have been a large storage of gasoline to be used for transportation of the army corps in Hiroshima. Therefore there is a possibility that various toxic substances, mutagenic or carcinogenic agents such as benzopyrene and other radiomimetic substances, chemical weapons (Yperit, Lewisite, etc.) could have been released from various facilities which were destroyed at the time of the atomic bombing. After the German surrender, in May 1945, it was reported in June, in Japan, that the USA might attempt landing on Japan mainland, and that they might be planning massive use of chemical weapons all over Japan on that occasion.

All cases were assessed for hepatitis B surface antigen (HB sub(s) Ag) using orcein and aldehyde fuchsin staining. The incidence of PLC was 2.0 times higher in Nagasaki than in Hiroshima which was statistically significant, but the prevalence of liver cirrhosis showed hardly any difference between the two cities. Meaningful findings that may possibly explain the higher incidence of PLC in Nagasaki were that the presence of HB sub(s) Ag in the liver of patients without overt liver disease was 2.3 times higher in Nagasaki than in Hiroshima, and the prevalence of liver cirrhosis associated with PLC, especially that of posthepatitic cirrhosis with PLC, was almost 2.0 times higher in Nagasaki than in Hiroshima. In both cities a suggestive relationship of radiation dose with the prevalence of liver cirrhosis was noted but not with PLC. We believe that the higher incidence of PLC in Nagasaki is attributable to HB virus infection, though other factors, such as immunological competence affected by radiation, cannot be excluded.

This progress report relates progress in the various research projects evaluating the late health effects, both somatic and genetic, resulting from radiation exposure of the survivors of the atomic bombs at Hiroshima and Nagasaki, Japan. Considerable progress has been made in the collection and utilization of the various epidemiological data bases. These include the Life Span Study, (LSS) cohort, the Adult Health Study (AHS) cohort, the In Utero cohort, the leukemia registry and the F-1 Study population. Important progress has been made in using RERF Tumor and Tissue Registry records for evaluation of cancer incidence and radiation risk estimates for comparison with cancer mortality and risk in the LSS cohort. At the present time, a manuscript on the incidence of solid tumors (1950-1987) is undergoing internal and external review for publication as an RERF Technical report (TR) and for publication in a peer-reviewed scientific journal. In addition, manuscripts are in preparation on (1) a comprehensive report on the incidence of hematological cancers, including analysis of leukemia by cell type (1950-1987), (2) a general description of Tumor Registry operations and (3) a comparison of incidence- and mortality-based estimates of radiation risk in the LSS cohort.

Hiroshima - Monday August 6, 1945, 8h15 a.m

International Nuclear Information System (INIS)

Hersey, John; Belmont, Georges; Haas, Pascale

2011-01-01

On 6 August 1945 at 8.15 a.m., Hiroshima was destroyed by the first atom bomb ever dropped on a city, killing one hundred thousand men, women and children in its white fury. This book, John Hersey's journalistic masterpiece, tells what happened on that day. Told through the memories of six civilians who survived against the odds, this timeless, powerful and compassionate document tells the moments that have preceded and followed the atomic explosion. John Hersey's spare, devastating report on the attack was first published in the New Yorker in 1946. Written in the immediate aftermath of the disaster, it is a classic piece of journalism, and a defining moment of the nuclear age

Sediment core samples were collected from Hiroshima Bay in the Seto Inland Sea, western Northwest Pacific Ocean, and their 239+240 Pu activities and 240 Pu/ 239 Pu atom ratios were determined by sector field ICP-MS. The activities of 239+240 Pu ranged from 0.556 ± 0.025 to 0.745 ± 0.023 mBq/g. The atom ratios of 240 Pu/ 239 Pu were almost constant within the whole depth; the average value was 0.227 ± 0.014. This atom ratio was significantly higher than the mean global fallout ratio of 0.18, proving the presence of close-in fallout Pu that originated from the Pacific Proving Ground (PPG). The water masses exchanges between the Kuroshio Current and the Seto Inland Sea brought the PPG source Pu to this area, then Pu was extensively scavenged into sediment particles supplied by the rivers around the bay. The relative contributions of the global fallout Pu and the PPG close-in fallout Pu were evaluated by the two end-member mixing model. The contribution of the PPG close-in fallout was 38-41% of the total Pu in sediment. The remaining 59-62% was attributed to direct global fallout and the land-origin Pu transported by the rivers around the Hiroshima Bay. (author)

This in vitro study evaluated the phagocytic and bactericidal activities of leukocytes in aliquots of whole blood from Hiroshima and Nagasaki atomic bomb survivors for Staphylococcus aureus. The data were analyzed by multiple linear regression. Any significant effects of exposure to A-bomb radiation could not be detected for both phagocytic and bactericidal activities of whole blood from A-bomb survivors. In addition, there were no significant effects of age categories, sex or city, except in neutrophil counts. (J.P.N.)

Ophthalmology research protocol, Hiroshima - Nagasaki

Energy Technology Data Exchange (ETDEWEB)

Miller, R J; Fujino, Tadashi; Nefzger, M D

1964-05-21

Several large ophthalmic studies have been made at ABCC. However, all preceded the final identification and definition of the Master Sample which unifies the three present major research studies, and T57D estimates were not available. For these reasons it seemed highly desirable to undertake another ophthalmic study which would both relate to the present program and utilize available dose information. Consequently, in 1962 a consultant in ophthalmology, Dr. P.J. Leinfelder visited ABCC to acquaint himself with the ABCC program and facilities, and he prepared the broad plan for this study. The present document describes the detailed working program which developed from this initial plan. For the period 1963 to 1964, investigation will be directed towards detection and evaluation of the following possible late effects of exposure to ionizing radiation: lens opacities; accelerated aging; and decreased acuity. 43 references, 1 figure, 4 tables.

Epidemiologic research program: Selected bibliography

International Nuclear Information System (INIS)

1993-05-01

This bibliography is a current listing of scientific reports from epidemiologic and related activities sponsored by the Department of Energy. The Office of Epidemiology and Health Surveillance now is the departmental focal point for these activities and any others relating to the study of human health effects. The Office's mission is evolving to encompass the new role of the Department in environmental restoration, weapons dismantlement and nuclear material storage, and development of new energy technologies. Publications in these areas will be included in future editions of the bibliography. The present edition brings the listing up to date, and should facilitate access to specific reports. The program has been divided into several general areas of activity: the Radiation Effects Research Foundation, which supports studies of survivors of the atomic weapons in Hiroshima and Nagasaki; mortality and morbidity studies of DOE workers; studies on internally deposited alpha emitters; medical/histologic studies; studies on the genetic aspects of radiation damage; community health surveillance studies; and the development of computational techniques and of databases to make the results as widely useful as possible

Clinical survey to detect diabetes mellitus, Hiroshima

Energy Technology Data Exchange (ETDEWEB)

Rudnick, P A; Anderson, Jr, P S

1961-07-19

Data from this study are in agreement with the general observations that diabetes is not uncommon in Japan. In an adult study population in Hiroshima 108 patients with diabetes were detected, yielding the prevalence rate of 3.02 percent. Nearly one-half of the patients were diagnosed initially as a result of the routine detection program. Although in females a trend with exposure is suggested by the raw data no statistically significant differences could be demonstrated. However, the size of the sample involved does not permit confident negative conclusions. Additional clinical and laboratory observations were completed in order to characterize the manifestation of diabetes in these subjects. Late manifestations of diabetes frequently were found, but atherosclerotic complications were nonexistent. This is considered to be related to the low fat, high carbohydrate diet of the Japanese. The lack of ketosis, apparently low prevalence rate for juveniles, and male preponderance suggest that diabetes in Japan differs from the disease found in many Western countries. 69 references, 1 figure, 9 tables.

Spatial analysis of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (Sea-Nine 211) concentrations and probabilistic risk to marine organisms in Hiroshima Bay, Japan

We analyzed the spatial distribution of an antifouling biocide, 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (Sea-Nine 211) in the surface water and sediments of Hiroshima Bay, Japan to determine the extent of contamination by this biocide. A quantitative estimate of the environmental concentration distribution (ECD) and species sensitivity distributions (SSDs) for marine organisms were derived by using a Bayesian statistical model to carry out a probabilistic ecological risk analysis, such as calculation of the expected potentially affected fraction (EPAF). The spatial distribution analysis supported the notion that Sea-Nine 211 is used mainly for treatment of ship hulls in Japan. The calculated EPAF suggests that approximately up to a maximum of 0.45% of marine species are influenced by the toxicity of Sea-Nine 211 in Hiroshima Bay. In addition, estimation of the ecological risk with a conventional risk quotient method indicated that the risk was a cause for concern in Hiroshima Bay. - Highlights: • Spatial distribution analysis exhibits the dynamics of Sea-Nine 211 in Hiroshima Bay. • Probabilistic ecological risk of the biocide was estimated with a Bayesian approach. • Approximately up to 0.45% of marine species were possibly influenced by the toxicity. • The risk analysis concludes that Sea-Nine 211 should be a priority for further work. - Spatial distribution of an antifouling biocide and quantification of its ecological risk were elucidated

Satoh, Kenichi; Otani, Keiko; Tonda, Tetsuji

2012-01-01

An epidemiological study was performed on the black rain as a death risk factor of survivors in Hiroshima Uda's (U) light to heavy black rain regions using the positional parameters at their exposure. Subjects were 27,610 A-bomb survivors at Jan. 1, 1970 with known positional coordinate and direct dose at explosion, followed until Dec. 31, 2009, whose endpoint was defined to be their all deaths due to cardiovascular, cerebrovascular diseases, pneumonia, cancers, etc. Confounding factors were sex (11,457 males/16,153 females), age at exposure (av. 25 y) and dose (av. 0.045 Gy), with which analysis was done by Cox proportional hazard model. The confounding interaction of the age/U region was found significant: e.g., at the exposed age 25 y, the hazard ratio was calculated to be 1.084, indicating about 8% higher hazard ratio of U region than the area outside of U. When the effect of the sex, exposed age and direct dose were adjusted to be minimized, the risk was found distributed mainly in concentric circle from hypocenter, yet still the effect of indirect exposure was observed though. When the distance instead of the indirect dose was used as an explanatory variable, it resulted in being significant with no significance of the direct exposure dose. Risk map employing the positional information at explosion revealed that the risk distribution was locally different even in U region itself. Thus this study suggested that the black rain was a mortality risk factor in the U raining region of Hiroshima. (T.T.)

1983-10-01

This is the fourth inventory of ABCC-RERF autopsies which covers those performed from 1948-80 (the other three inventories). For general information the introduction of the third inventory (1948-70) is included with some modification, and deaths and autopsy rates for 1971-80 are added. ABCC-RERF performed 10,096 autopsies (6,555 in Hiroshima and 3,541 in Nagasaki) from 1948 to 1980. Protocols, tissues, sections, smears, etc., assembled by the collaborating institutions were examined by members of the ABCC Department of Pathology who completed ABCC records for each case. Copies of all protocols, gross tissues, and histological sections were placed in a designated repository in the Medical School of each city where they are available to all qualified and interested investigators.

Sensitivity/uncertainty analysis for free-in-air tissue kerma due to initial radiation at Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Lillie, R.A.; Broadhead, B.L.; Pace, J.V. III

1988-01-01

Uncertainty estimates and cross correlations by range/survivor have been calculated for the Hiroshima and Nagasaki free-in-air (FIA) tissue kerma obtained from two-dimensional air/ground transport calculations. The uncertainties due to modeling parameter and basic nuclear transport data uncertainties were calculated for 700-, 1000-, and 1500-m ground ranges. Only the FIA tissue kerma due to initial radiation was treated in the analysis; the uncertainties associated with terrain and building shielding and phantom attenuation were not considered in this study. Uncertainties of --20% were obtained for the prompt neutron and secondary gamma kerma and 30% for the prompt gamma kerma at both cities. The uncertainties on the total prompt kerma at Hiroshima and Nagasaki are --18 and 15%, respectively. The estimated uncertainties vary only slightly by ground range and are fairly highly correlated. The total prompt kerma uncertainties are dominated by the secondary gamma uncertainties, which in turn are dominated by the modeling parameter uncertainties, particularly those associated with the weapon yield and radiation sources

Incidence of leukemia in a fixed cohort of atomic bomb survivors and controls, Hiroshima and Nagasaki October 1950 - December 1978

The present analysis of leukemia incidence is confined to 189 cases in Hiroshima and Nagasaki. The analysis again demonstrates that the risk of all types of leukemia has increased with dose in both cities except among individuals who received less than 100 rad in kerma total dose in Nagasaki. The shape of the dose-response curve is different in the two cities and between the two major types of leukemia (acute leukemia and chronic granulocytic leukemia), though the average marrow total dose is quite similar in each total kerma dose class in the two cities. The present findings are quite consistent with those described in the previous report. The excess risk among survivors who received 100 rad or more kerma total dose has gradually declined with years after exposure in both cities. It had disappeared among Nagasaki survivors by 1970 (25 years after exposure) but the risk was still high even after 1970 among exposed survivors in Hiroshima who were 30 years of age or older ATB. The leukemogenic effect of radiation differs in relation to dose, age ATB, and duration after exposure between Hiroshima and Nagasaki survivors. The analysis has again supported previous observations that the leukemogenic effect of radiation in those individuals exposed at younger ages ATB was greater in the early postbomb period and declined more rapidly in subsequent years, while the effect in older individuals ATB appeared later and persisted longer.

A new program sponsored by The Barrett Foundation in the University of Vermont College of Engineering and Mathematical Sciences (UVM) supports undergraduate students in Environmental Engineering, Earth and Environmental Sciences to pursue independent summer research projects. The Barrett Foundation, a non-profit organization started by a UVM Engineering alum, provided a grant to support undergraduate research. Students must work with at least two different faculty advisors to develop project ideas, then independently prepare a research proposal and submit it to a faculty panel for review. The program was structured as a scholarship to foster a competitive application process. In the last three years, fourteen students have participated in the program. The 2007 Barrett Scholars projects include: - Using bacteria to change the chemistry of subsurface media to encourage calcite precipitation for soil stability and pollutant sequestration - Assessing structural weaknesses in a historic post and beam barn using accelerometers and wireless data collection equipment - Using image processing filters to 1) evaluate leaf wetness, a leading indicator of disease in crops and 2) assess the movement of contaminants through building materials. - Investigating the impact of increased water temperature on cold-water fish species in two Vermont streams. - Studying the impacts of light duty vehicle tailpipe emissions on air quality This program supports applied and interdisciplinary environmental research and introduces students to real- world engineering problems. In addition, faculty from different research focuses are presented the opportunity to establish new collaborations around campus through the interdisciplinary projects. To date, there is a successful publication record from the projects involving the Barrett scholars, including students as authors. One of the objectives of this program was to provide prestigious, competitive awards to outstanding undergraduate engineers

Space Weather Research at the National Science Foundation

Moretto, T.

2015-12-01

There is growing recognition that the space environment can have substantial, deleterious, impacts on society. Consequently, research enabling specification and forecasting of hazardous space effects has become of great importance and urgency. This research requires studying the entire Sun-Earth system to understand the coupling of regions all the way from the source of disturbances in the solar atmosphere to the Earth's upper atmosphere. The traditional, region-based structure of research programs in Solar and Space physics is ill suited to fully support the change in research directions that the problem of space weather dictates. On the observational side, dense, distributed networks of observations are required to capture the full large-scale dynamics of the space environment. However, the cost of implementing these is typically prohibitive, especially for measurements in space. Thus, by necessity, the implementation of such new capabilities needs to build on creative and unconventional solutions. A particularly powerful idea is the utilization of new developments in data engineering and informatics research (big data). These new technologies make it possible to build systems that can collect and process huge amounts of noisy and inaccurate data and extract from them useful information. The shift in emphasis towards system level science for geospace also necessitates the development of large-scale and multi-scale models. The development of large-scale models capable of capturing the global dynamics of the Earth's space environment requires investment in research team efforts that go beyond what can typically be funded under the traditional grants programs. This calls for effective interdisciplinary collaboration and efficient leveraging of resources both nationally and internationally. This presentation will provide an overview of current and planned initiatives, programs, and activities at the National Science Foundation pertaining to space weathe research.

1982-03-01

The data from the RERF Leukemia Registry for the years 1946-75 were used to determine the distribution of onset of acute leukemia and chronic granulocytic leukemia among atomic bomb survivors in relation to city, dose, and age at the time of the bomb (ATB). A total of 509 confirmed leukemia cases (297 in Hiroshima and 212 in Nagasaki) have occurred among A-bomb survivors in the open populations of these cities in these years. Analysis revealed that the onset of both acute leukemia and chronic granulocytic leukemia tends to shift to earlier years with increasing dose in Hiroshima, but in Nagasaki, although the onset of both types of leukemia was earlier in the high dose group than in the low dose or control groups, the latter two groups did not differ. The distribution of onset of acute leukemia in the three dose groups also depended upon age ATB. While the distribution of onset of acute leukemia among those survivors whose age ATB was less than 30 differed significantly in the three dose classes, this tendency was not observed among those individuals whose age ATB was 30 years or more. For chronic granulocytic leukemia, the onset was shifted to earlier years in the high dose group than in the control group regardless of age ATB in Hiroshima. These findings support the pattern of leukemogenesis observed in A-bomb survivors in the Life Span Study sample, a fixed cohort, in relation to city, dose, age ATB, and years after exposure.

Takeshita, Kenji

1976-01-01

An external exposure dose from residual activity (induced radioactivity in the fallout areas and radioactive fallout in the ''black rain'' area) caused by an atomic bomb in Hiroshima was estimated. The integrated doses to the infinite time averaged 101 rads in the atomic bombed area of Hiroshima and 32 rads in that area of Nagasaki. According to the measurement by investigators, the integrated doses of the external exposure dose due to radioactive fallout averaged 13 rads. The amount of 137 Cs in soils was determined in the southest slanting surface

Concentration of Antifouling Biocides and Metals in Sediment Core Samples in the Northern Part of Hiroshima Bay

Full Text Available Accumulation of Ot alternative antifoulants in sediment is the focus of this research. Much research had been done on surface sediment, but in this report, the accumulation in the sediment core was studied. The Ot alternative antifoulants, Diuron, Sea-Nine211, and Irgarol 1051, and the latter’s degradation product, M1, were investigated in five samples from the northern part of Hiroshima Bay. Ot compounds (tributyltin (TBT and triphenyltin (TPT were also investigated for comparison. In addition, metal (Pb, Cu, Zn, Fe and Mn levels and chronology were measured to better understand what happens after accumulation on the sea floor. It was discovered that Ot alternative antifoulant accumulation characteristics in sediment were like Ot compounds, with the concentration in the sediment core being much higher than surface sediment. The concentration in sediment seems to have been affected by the regulation of Ot compounds in 1990, due to the concentration of Ot alternative antifoulants and Ot compounds at the survey point in front of the dock, showing an increase from almost the same layer after the regulation.

The 20th Hiroshima Cancer seminar focused upon breast cancer research and treatment particularly on the mechanism of tumorigenesis and drug resistance and development of novel therapeutics. Several molecules such as retinoblastoma and p16 were raised as key factors in tumorigenesis and invasiveness. Estrogen-related pathways seem to be closely involved in the process. For the tumor lacking hormone receptor and human epidermal growth factor 2, some other mechanisms could be responsible. It seems that MicroRNA 22 directing some putative targets such as SIRT1, Sp1 and CDK6 plays a crucial role in breast tumor growth and metastasis. In addition, ribophorin and the associated molecules might be engaged in breast cancer stemness. Obviously, these molecules provide potential for therapeutic targets. It was also discussed about new drug development such as anti-human epidermal growth factor 2 therapy, anti-angiogenesis, pro-tumor aspects of anti-cancer therapy and application of circulating markers for monitoring, imaging and health-care system. Furthermore, we discussed risk factors, prevention and screening to reduce invasive cancers as well. Throughout the conference, panelists and attendee indicated the importance of translational research and biomarker exploration in order to realize efficient and individualized therapy for breast cancer.

Health effects on individuals and health services of the Hiroshima and Nagasaki bombs

Ohkita, T.

1984-01-01

Human injuries caused by the A-bomb can be categorized as the result of thermal rays, ionizing radiation, or blast. Many persons sustained injuries from more than one cause, any one of which could have been fatal. In addition to such direct injuries, indirect injuries were sustained, caused by fire or the fall of rubble from demolished buildings. The severity of early A-bomb injuries was directly proportional to distance from the hypocentre. Many hospitals and clinics throughout Hiroshima City and Nagasaki City were destroyed or damaged depending on their distance from the hypocentre and the extent to which they were shielded topographically

Audiometric changes with age in Hiroshima: a statistical study

Energy Technology Data Exchange (ETDEWEB)

Hollingsworth, J W; Ishii, Goro

1960-10-01

Audiometry observations were analyzed for 290 irradiated survivors of the 1945 atomic bomb in Hiroshima and in 293 nonirradiated subjects. The study was undertaken in order to determine the age changes in audiology in irradiated and nonirradiated subjects as well as to investigate the pattern of hearing levels in a Japanese population for comparison with patterns in Caucasians. The following statistical observations were made. Correlation between hearing levels for right and left ear. Correlation between hearing levels at various cycles. Changes in hearing levels by age and sex. The relation between age and decibel loss was not linear and correlation ratios with age were 0.45 to 0.72. Audiometry seems to be of some value as one of a battery of tests of physiologic aging designed for detection of irradiation induced nonspecific aging acceleration. In this relatively small sample, no differences in hearing acuity were detected in the atomic bomb survivors as compared with the control sample. 6 references, 3 figures, 9 tables.

Hiroshima Diary - August 6-September 30, 1945

Hachiya, Michihiko; Duran, Simon

Michihiko Hachiya was director of the Hiroshima Communications Hospital when the world's first atomic bomb was dropped on the city. Though his responsibilities in the appalling chaos of a devastated city were awesome, he found time to record the story daily, with compassion and tenderness. Hachiya's diary covers the period from Aug. 6, 1945 to Sept. 30, 1945. He described the effects of the atomic bomb blast from its first flash in the early morning as he rested from his night shift as an air warden at the hospital. The force of the blast stripped all the clothes from his body but he and his wife survived, however they both received serious burns to their bodies and had to journey to the hospital Michihiko worked at. He spent the night in the care of the hospital staff who were not seriously injured and started making his daily rounds that he would have normally made as a doctor. As time passes an understanding of what hit their city clears up, and historical events such as the surrender of Japan are brought up. The condition of the hospital also drastically improves as more medical supplies are brought into the city, allowing them to better treat patients

DOE (Department of Energy) Epidemiologic Research Program: Selected bibliography

Energy Technology Data Exchange (ETDEWEB)

1991-01-01

The objective of the Department of Energy (DOE) Epidemiologic Research Program is to determine the human health effects resulting from the generation and use of energy, and from the operation of DOE facilities. The program has been divided into seven general areas of activity: the Radiation Effects Research Foundation (RERF) which supports studies of survivors of the atomic weapons in Hiroshima and Nagasaki, mortality and morbidity studies of DOE workers, studies on internally deposited alpha emitters, medical/histologic studies, studies on the genetic aspects of radiation damage, community health surveillance studies, and the development of computational techniques and of databases to make the results as widely useful as possible. Excluding the extensive literature from the RERF, the program has produced 380 publications in scientific journals, contributing significantly to improving the understanding of the health effects of ionizing radiation exposure. In addition, a large number of public presentations were made and are documented elsewhere in published proceedings or in books. The purpose of this bibliograhpy is to present a guide to the research results obtained by scientists supported by the program. The bibliography, which includes doctoral theses, is classified by national laboratory and by year. Multi-authored studies are indicated only once, according to the main supporting laboratory.

Tissue kerma vs distance relationships for initial nuclear radiation from the atomic devices detonated over Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Kerr, G.D.; Pace, J.V. III; Scott, W.H. Jr.

1983-06-01

Initial nuclear radiation is comprised of prompt neutrons and prompt primary gammas from an exploding nuclear device, prompt secondary gammas produced by neutron interactions in the environment, and delayed neutrons and delayed fission-product gammas from the fireball formed after the nuclear device explodes. These various components must all be considered in establishing tissue kerma vs distance relationships which describe the decrease of initial nuclear radiation with distance in Hiroshima and in Nagasaki. The tissue kerma at ground evel from delayed fission-product gammas and delayed neutrons was investigated using the NUIDEA code developed by Science Applications, Inc. This code incorporates very detailed models which can take into account such features as the rise of the fireball, the rapid radioactive decay of fission products in it, and the perturbation of the atmosphere by the explosion. Tissue kerma vs distance relationships obtained by summing results of these current state-of-the-art calculations will be discussed. Our results clearly show that the prompt secondary gammas and delayed fission-product gammas are the dominant components of total tissue kerma from initial nuclear radiation in the cases of the atomic (or pure-fission) devices detonated over Hiroshima and Nagasaki

Analysis of atomic-bomb survivor data: ongoing research and opportunities for the future

International Nuclear Information System (INIS)

Upton, A.C.

1984-01-01

Study of the atomic bomb survivors has provided uniquely valuable information about the types of effects that are produced by ionizing radiation and their relation to dose, age at exposure, time after irradiation, and other variables. There are still, however, many unresolved questions requiring further investigation. These include reassessment of the dosimetry in both Hiroshima and Nagasaki; continued follow-up of survivors for cancer and other late effects, especially those who were exposed early in life and are just now reaching the age when the common cancers of adult life make their appearance; further evaluation of the possibility of measuring genetic effects in the children of survivors; and continued longitudinal investigation of risk factors predisposing to cancer, preneoplastic lesions, and other diseases. To the extent that a strong statistical foundation is essential to such investigations, the high calibre and sophistication of ongoing statistical research at RERF augers well for the future. 30 references, 4 figures

The delayed effects of radiation exposure among atomic bomb survivors, Hiroshima and Nagasaki, 1945-79

Finch, S.C.; Moriyama, I.M.

1980-07-01

The most important radiation-induced late medical effect in the atomic bomb survivors of Hiroshima and Nagasaki has been the increased occurrence of certain neoplasms, specifically, leukemia and cancers of the thyroid, lung, and breast. Other definite radiation-related effects include an increase in posterior lenticular opacities, chromosome aberrations in peripheral blood lymphocytes, and some abnormalities of growth and development following irradiation while in utero or during childhood. Moderate to fairly strong associations between A-bomb exposure and the increased occurrence of stomach cancer, multiple myeloma, and several other types of cancer have been observed. Radiation relationships also are suggestive for alterations of certain aspects of immune mechanisms and the increased occurrence of myelofibrosis. No increase in genetic effects has been demonstrated in the children born of exposed parents, and studies to data have been negative for evidence of increased infertility, accelerated aging, or increased mortality from diseases other than cancer. In general, the radiation dose-response relationships for most positive effects have been higher in Hiroshima than in Nagasaki, and the shape of the dose-response curves for certain effects is different in the two cities. These differences may be related to differences in the quality of the radiation from the two A-bombs. For several radiation-related effects the latent period following exposure is shorter and the incidence rate is higher in personse exposed when young as compared to exposure later in life. (author)

Combined Effect of an Atmospheric River and a Cut-off Low in Hiroshima Flooding Event on August 19, 2014

Science.gov (United States)

Takayabu, Y. N.; Hirota, N.; Kato, M.; Arakane, S.

2015-12-01

An extraordinary precipitation over 100 mmhr-1in Hiroshima on August 19, 2014, caused a flash flood which resulted in 74 fatalities and collapse of 330 houses. In order to examine the meteorological background of this flooding event, we carried out a detailed analysis utilizing rain gauge data, satellite precipitation dataset, and a meso scale and a global scale objective analyses provided from the Japan Meteorological Agency. Then, we performed numerical experiments using a nonhydrostatic compressible equation model called the Cloud-Resolving Storm Simulator (CReSS). As a result, a combined effect of an atmospheric river (AR) and a cut-off low (COL) in this flooding event was elucidated. During the event, a filamentary transport of moisture extending from the Indochina Peninsula to the Japanese Islands was observed along the southern side of the subtropical jet, forming an AR. This AR had a deep structure with an amount of free tropospheric moisture comparable to that of the boundary layer. Concurrently, there was a COL, detached from the Mid-Pacific Trough, moving northwestward toward the Japanese Archipelago. With various sensitivity experiments, we concluded that a mid-tropospheric instability associated with the cold core of the COL and a dynamical ascent induced in its foreside, collaboratively worked with the anomalous moisture in the free troposphere associated with the AR, to extraordinarily enhance the precipitation over Hiroshima region. An orographic effect to concentrate the precipitation in this region was also confirmed. An implication on a difference in effects of AR in this event with a climatologically moist boundary layer, from those in the US west coast with a very dry environment, was also obtained.

The role of foundations: Rockefeller Foundation.

Science.gov (United States)

Rockefeller, David

The consequences of climate change and the impacts of human activity on the environment have made it clearer than ever before that we must evolve our current model of public health to better account for the inextricable link between human health and the natural systems on which it depends-creating a "public health 2.0" that builds on the innovations of the twentieth century to account for a world where humans have bypassed planetary boundaries to achieve well-being. First coined at the Rockefeller Foundation's Centennial gathering in Beijing in 2013, "Planetary Health" will factor in future health and environmental harms over present-day gains, particularly those that disproportionately affect the poor and those in developing nations. To build this new field, foundations must address the challenge of information, increasing support for research to bridge knowledge gaps on the links between economic development, natural systems, and human health.

Adult health study. Hiroshima preliminary report, 1958-1959

Energy Technology Data Exchange (ETDEWEB)

Hollingsworth, J W; Anderson, Jr, P S

1961-06-28

The first 4151 clinical examinations of radiation exposed and nonexposed persons in the Hiroshima Adult Health Study have been tabulated and reviewed. No evident differences in past history, medical symptoms, physical examination, laboratory findings, nor disease incidence could be related to the atomic radiation in 1945. The sample is small and represents only a portion of the first cycle of an examination procedure that is planned to continue indefinitely at approximately two year intervals. This report, consisting of a review of the program and the findings in this preliminary sample, includes extensive tabular data (Tables 28-65) from the coded medical information. It was not expected that radiation induced changes would be evident from this sample unless they were of unexpected prominence. The report was prepared primarily to describe the problems inherent in an epidemiologic medical study of this sort, and to review the type of data that can be obtained for future analyses. This analysis was conducted to pinpoint some of the problems; to assist others contemplating this type of medical study; to illuminate for ABCC the data that are being collected; and to suggest ways to use these data most effectively. 16 references, 1 figure, 65 tables.

The standardized mortality ratios of A-bomb survivors in Hiroshima Prefecture between 1973 and 1977 were compared with those of non-exposed population in this prefecture. In the malignant neoplasms, the ratios for leukemia, liver, breast, lung, larynx, brain, bone, skin, uterus, bladder and colon were higher than non-exposed. Other than the neoplasms, the ratios for cirrhosis of liver, diabetes, hypertensive diseases and blood and blood-forming organs were higher than nonexposed, while those for heart diseases, cerebro-vascular diseases, senility, gastro-enteritis and accidents were lower than non-exposed.

When using gamma-ray spectrometry performed deep underground, it is possible to measure 60Co activities down to 0.1 mBq in steel samples of some 100 g without any pre-concentration. It is thus still possible to measure 60Co induced by neutrons from the atomic bomb explosion in Hiroshima in pieces of steel collected at distances up to about 1200 m slant range. The results of non-destructive measurements of eight steel samples are compared with the 1986 Dose Re-Evaluation (DS86) model calculations.

Private Philanthropy and Basic Research in Mid-Twentieth Century America: The Hickrill Chemical Research Foundation.

Gortler, Leon; Weininger, Stephen J

2017-02-01

The Hickrill Chemical Research Foundation, located north of New York City on the estate of its patrons, Sylvan and Ruth Alice Norman Weil, had a short (1948-59) but productive life. Ruth Alice Weil received a Ph.D. in organic chemistry in 1947, directed by William von Eggers Doering of Columbia University. She intended that Hickrill contribute to cancer chemotherapy while providing resources for Doering's more speculative research. Ultimately, Doering's commitment to theoretical organic chemistry set Hickrill's research agenda. Lawrence Knox, an African American with a Harvard Ph.D., supervised the laboratory's daily activities. Hickrill's two dozen postdoctoral fellows produced path-breaking results in Hückel aromatic theory and reactive intermediate chemistry, fostering the postwar emphasis on "basic science." This essay places the Laboratory's successes in the wider context of postwar politics and scientific priorities. Private philanthropic support of basic science arose because it received little pre-World War II government support. In the immediate postwar period, modest organisations like Hickrill still met a need, but the increasing governmental defence- and non-defence-related support for science eventually rendered them unnecessary.

Can Innate, modular "foundations" explain morality? Challenges for Haidt's Moral Foundations Theory.

Science.gov (United States)

Suhler, Christopher L; Churchland, Patricia

2011-09-01

Jonathan Haidt's Moral Foundations Theory is an influential scientific account of morality incorporating psychological, developmental, and evolutionary perspectives. The theory proposes that morality is built upon five innate "foundations," each of which is believed to have been selected for during human evolution and, subsequently, tuned-up by learning during development. We argue here that although some general elements of Haidt's theory are plausible, many other important aspects of his account are seriously flawed. First, innateness and modularity figure centrally in Haidt's account, but terminological and conceptual problems foster confusion and ambiguities. Second, both the theory's proposed number of moral foundations and its taxonomy of the moral domain appear contrived, ignoring equally good candidate foundations and the possibility of substantial intergroup differences in the foundations' contents. Third, the mechanisms (viz., modules) and categorical distinctions (viz., between foundations) proposed by the theory are not consilient with discoveries in contemporary neuroscience concerning the organization, functioning, and development of the brain. In light of these difficulties, we suggest that Haidt's theory is inadequate as a scientific account of morality. Nevertheless, the theory's weaknesses are instructive, and hence, criticism may be useful to psychologists, neuroscientists, and philosophers attempting to advance theories of morality, as well as to researchers wishing to invoke concepts such as innateness and modularity more generally.

Corporate Ownership by Industrial Foundations

DEFF Research Database (Denmark)

Thomsen, Steen

1999-01-01

Industrial foundations are self-governing non profit institutions that own business companies. This ownership structure is found in a fair number of Northern European companies, some of them successful world class competitors. Standard agency theory would predict foundation-owned companies...... to be relatively inefficient since they lack monitoring by residual claimants and access to equity finance from the stock market. Nevertheless, empirical research (Thomsen 1996) has found that Danish foundation-owned companies do no worse in terms of profitability and growth than companies with dispersed ownership...

Malignant lymphoma in survivors of the atomic bomb, Hiroshima

Energy Technology Data Exchange (ETDEWEB)

Anderson, R E; Ishida, Kenzo

1964-02-01

The present study demonstrates an increased prevalence of Hodgkin's disease, lymphosarcoma and multiple myeloma in survivors within 1400 m from the hypocenter in Hiroshima who had surgical or post-mortem examinations at ABCC. Reticulum cell sarcoma appears to have decreased prevalence in this same group. The pathologic material demonstrating these relationships consists of 91 cases of unequivocal malignant lymphoma and is drawn from two essentially independent ABCC sources, the autopsy series and diagnostic lymph node biopsies. A consideration of the epidemiologic characteristics of this material supports the view that the increase in prevalence is a reflection of the occurrence of lymphoma in the general population of survivors within 1400 m of the hypocenter. In addition, among such persons autopsied at ABCC there appears to be a shift to death at an earlier age than is found in the other comparison groups. The possible implications of this are discussed. A comparison of the lymphomas examined shows no morphologic differences in the corresponding diagnostic categories between the various comparison groups. 21 references, 3 figures, 3 tables.

1990-10-01

During the two-year period from August 1986 to July 1988, the prevalence of hyperparathyroidism (HPT) was determined among A-bomb survivors and unexposed control subjects in Hiroshima. The diagnosis of HPT was determined biochemically, based upon the presence of consistent hypercalcemia and elevated serum parathyroid hormone levels. Among a population of 4,675 individuals (1,527 males, 3,148 females), primary HPT was diagnosed in 22 (3 males, 19 females). Of these, 8 underwent surgery, of whom 6 had a single parathyroid adenoma and 2 had parathyroid hyperplasia. HPT was more prevalent among the A-bomb survivors who received higher radiation doses (p <.001 for linear trend). The prevalence rates predicted from the model were 0.204% (±0.094%) at 0 Gy and 0.893% (±0.237%) at 1 Gy. The background rate of HPT did not differ significantly by sex or by age at the time of the bombing, although the effect of radiation exposure was greater for individuals exposed at a younger age (p <.01).

Late radiation responses in man: Current evaluation from results from Hiroshima and Nagasaki

Science.gov (United States)

Schull, William J.

Among the late effects of exposure to the atomic bombings of Hiroshima and Nagasaki, none looms larger than radiation related malignancies. Indeed, the late effects of A-bomb radiation on mortality appear to be limited to an increase in malignant tumors. At present, it can be shown that cancers of the breast, colon, esophagus, lungs, stomach, thyroid, and urinary tract as well as leukemia and multiple myeloma increase in frequency with an increase in exposure. No significant relationship to radiation can as yet be established for malignant lymphoma, nor cancers of the rectum, pancreas or uterus. Radiation induced malignancies other than leukemia seem to develop proportionally to the natural cancer rate for the attained age. For specific age-at-death intervals, both relative and absolute risks tend to be higher for those of younger age at the time of bombing. Other late effects include radiation-related lenticular opacities, disturbances of growth among those survivors still growing at the time of exposure, and mental retardation and small head sizes among the in utero exposed. Chromosomal abnormalities too are more frequently encountered in the peripheral leucocytes of survivors, and this increase is functionally related to their exposure. Some uncertainty continues to surround both the quantity and quality of the radiation released by these two nuclear devices, particularly the Hiroshima bomb. A recent reassessment suggests that the gamma radiation estimates which have been used in the past may be too low at some distances and the neutron radiation estimates too high at all distances; moreover, the energies of the neutrons released now appear ``softer'' than previously conjectured. These uncertainties not sufficiently large, however, to compromise the reality of the increased frequency of malignancy, but make estimates of the dose response, particularly in terms of gamma and neutron exposures, tentative.

Moral foundations vignettes: a standardized stimulus database of scenarios based on moral foundations theory.

2015-12-01

Research on the emotional, cognitive, and social determinants of moral judgment has surged in recent years. The development of moral foundations theory (MFT) has played an important role, demonstrating the breadth of morality. Moral psychology has responded by investigating how different domains of moral judgment are shaped by a variety of psychological factors. Yet, the discipline lacks a validated set of moral violations that span the moral domain, creating a barrier to investigating influences on judgment and how their neural bases might vary across the moral domain. In this paper, we aim to fill this gap by developing and validating a large set of moral foundations vignettes (MFVs). Each vignette depicts a behavior violating a particular moral foundation and not others. The vignettes are controlled on many dimensions including syntactic structure and complexity making them suitable for neuroimaging research. We demonstrate the validity of our vignettes by examining respondents' classifications of moral violations, conducting exploratory and confirmatory factor analysis, and demonstrating the correspondence between the extracted factors and existing measures of the moral foundations. We expect that the MFVs will be beneficial for a wide variety of behavioral and neuroimaging investigations of moral cognition.

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is widely accepted as a rapid and sensitive technique for trace elemental analysis of solid materials and for local analysis of inhomogeneous materials (such as geological samples). Due to its direct solid sample analysis capability, LA-ICP-MS (using a quadrupole based ICP-MS and at the Research Center Juelich developed laser ablation system: Nd-YAG-laser, 226 nm, 10 Hz and 5 ns) is applied for the analysis of geological (granite) samples from Hiroshima. In order to prepare homogeneous targets, these samples were melted together with a lithium-borate mixture in a muffle furnace at 1050 degree c. Furthermore, for investigating of matrix effects the powder of these samples is mixed with graphite and pressed as targets for laser ablation. The quantification of the analysis results was carried out using granite (GM) as standard reference material. The relative sensitivity coefficients (RSCs) for most elements, which were determined for correction of the measured values, varied between 0.3 and 3

1990-01-01

A general adjoint Monte Carlo-forward discrete ordinates radiation transport calculational scheme has been created to study the effects of the radiation environment in Hiroshima and Nagasaki due to the bombing of these two cities. Various such studies for comparison with physical data have progressed since the end of World War II with advancements in computing machinery and computational methods. These efforts have intensified in the last several years with the U.S.-Japan joint reassessment of nuclear weapons dosimetry in Hiroshima and Nagasaki. Three principal areas of investigation are: (1) to determine by experiment and calculation the neutron and gamma-ray energy and angular spectra and total yield of the two weapons; (2) using these weapons descriptions as source terms, to compute radiation effects at several locations in the two cities for comparison with experimental data collected at various times after the bombings and thus validate the source terms; and (3) to compute radiation fields at the known locations of fatalities and surviving individuals at the time of the bombings and thus establish an absolute cause-and-effect relationship between the radiation received and the resulting injuries to these individuals and any of their descendants as indicated by their medical records. It is in connection with the second and third items, the determination of the radiation effects and the dose received by individuals, that the current study is concerned

A study was conducted on the pesticides Diuron, Irgarol 1051 and Fenitrothion in Kurose River water, Higashi Hiroshima, Japan for a period of one year to assess the contribution of agriculture and urban activities on pesticide pollution of the river. Samples were analysed by a reverse phase HPLC system. The maximum pesticide concentrations were; 4620 ng/L, 50 ng/L and 370 ng/L for Diuron, Irgarol 1051 and Fenitrothion, respectively. While Diuron and Fenitrothion were detected at all sites, Irgarol 1051 was only present at Izumi, a high density urban and industrial area which also registered the highest concentrations of the pesticides. The pattern showed by Diuron and Fenitrothion was linked to farming activities. Also, Diuron and Fenitrothion concentration correlated with pesticide utilization data for Hiroshima Prefecture. Irgarol 1051 showed a different pattern to that of Diuron and Fenitrothion and its source was attributed to paint. It was noted that 78% and 42% of water samples at Izumi sampling site exceeded the European Union (EU) guidelines for Diuron and Fenitrothion, respectively. Copyright © 2015 Elsevier B.V.

When using gamma-ray spectrometry performed deep underground, it is possible to measure {sup 60}Co activities down to 0.1 mBq in steel samples of some 100 g without any pre-concentration. It is thus still possible to measure {sup 60}Co induced by neutrons from the atomic bomb explosion in Hiroshima in pieces of steel collected at distances up to about 1200 m slant range. The results of non-destructive measurements of eight steel samples are compared with the 1986 Dose Re-Evaluation (DS86) model calculations.

Noncancer mortality based on the Hiroshima Atomic Bomb survivors registry over 30 years, 1968-1997

International Nuclear Information System (INIS)

Kasagi, Keiko

2002-01-01

The relation of radiation exposure with noncancer mortality was examined on 44,514 atomic bomb survivors (17,935 males, 26,579 females, and mean age 22.8±15.7 yrs at the time of bombing) registered at Research Institute for Radiation Biology and Medicine, Hiroshima University, based on mortality follow-up over 30 years, 1968-1997. Noncancer mortality was significantly related to radiation dose with relative risk of 1.06 at 1 Sv radiation dose, although weaker than the dose response in solid cancer mortality. The significant dose responses were observed especially in circulatory disease, stroke and urinary organ disease, and suggestive dose response in pneumonia. The temporal pattern in dose response by age at the time of bombing indicated that the relative risk of noncancer mortality was higher with follow-up period, which is contrary to a decreasing dose response in solid cancer mortality with follow-up period. The tendency was remarkable in those survivors younger at the time of bombing. These findings suggest that the significant radiation risk observed in noncancer mortality might increase as the proportion of younger survivors among atomic bomb survivors increases. (author)

ABCC-JNIH Adult Health Study, Hiroshima and Nagasaki 1958-1960: height-weight tables

Energy Technology Data Exchange (ETDEWEB)

Seigel, D

1962-11-14

From measurements taken in the Adult Health Study in Nagasaki and Hiroshima, tables of weight have been compiled. They are presented in the metric system, specific for height, sex, and age group. Five percentiles are presented as a guide for describing the distribution of weights. These values represent smoothing of the original data. This was accomplished by fitting second degree regression equations by least squares to the relationship of the logarithm of weight on height, separately for each age-sex group. This provided medians; other percentiles were obtained by adding or subtracting a term of the form KS, where K was taken from a table of normal deviates, and S was estimated from the data. The use and limitations of the tables were discussed. 10 tables.

We assessed the ability of the Manitoba Medical Service Foundation (MMSF, a small not-for-profit foundation affiliated with Manitoba Blue Cross) to determine the best candidates for selection to receive research funding support among new researchers applying to the Research Operating Grants Programme (ROGP). Using bibliometric and grants funding analyses, we retrospectively compared indices of academic outputs from five cohorts of MMSF-funded and not MMSF-funded applicants to the annual MMSF ROGP over 2008 to 2012, from 1 to 5 years after having received evaluation decisions from the MMSF enhanced grant review process. Those researchers funded by the MMSF competition (MMSF-funded) had a statistically significant greater number of publications, a higher h-index and greater national Tri-Council (TC) funding, versus those not selected for funding (not MMSF-funded). MMSF-funded applicants and the Manitoba research community have created a strong and rapid (within 1 to 5 years of receiving the MMSF grant) local economic return on investment associated with the MMSF ROGP that supports new investigators, of approximately nine-fold for TC grants by the principal investigator, and of 34-fold for the principal investigator on collaborative (total) TC grants. The use of small amounts of seed money for competitive research grants at early stages of an MMSF-funded applicant's career correlates with future short-term success of that applicant. The ability to correctly select promising candidates who subsequently demonstrate greater academic performance after the MMSF funding shows the selection process and the ROGP to be of merit. Multiple components may have contributed to this outcome, including a direct presentation and interview process of the candidate with five-person selection subcommittees, plus an assessment by an external reviewer (the enhanced grant review process). The selection methods used here may add value to the research grant selection processes of new

The basis of the presented model is the multistage process of carcinogenesis as a biological effect. It provides simultaneously the age-dependent mortality of spontaneous and radiation induced solid tumors and dose-effect relationships at any age after exposure. The model has been used to describe the solid cancer mortality rates of the atomic bomb survivors of Hiroshima and Nagasaki. It has characteristics of both relative and absolute risk projections depending on the age of exposure. (author)

In the last 3 decades the field of mechanics has seen spectacular progress due to the demand for applications in problems of cosmology, thermonuclear fusion, metallurgy, etc. This book provides a broad and thorough overview on the foundations of mechanics. It discusses theoretical mechanics and continuum mechanics, as well as phenomenological thermodynamics, quantum mechanics and relativistic mechanics. Each chapter presents the basic physical facts of interest without going into details and derivations and without using advanced mathematical formalism. The first part constitutes a classical exposition of Lagrange's and Hamiltonian's analytical mechanics on which most of the continuum theory is based. The section on continuum mechanics focuses mainly on the axiomatic foundations, with many pointers for further research in this area. Special attention is given to modern continuum thermodynamics, both for the foundations and applications. A section on quantum mechanics is also included, since the phenomenological description of various quantum phenomena is becoming of increasing importance. refs.; figs.; tabs

1966-07-21

A mail survey was conducted on 13,000 males in the JNIH-ABCC Life Span Study population aged 40 to 69 in January 1965. The information sought was largely related to what are considered to be risk factors in the development of cerebral and cardiovascular diseases. The questionnaire included such items as residential history, occupation, physical activity, smoking, dietary custom, educational history, medical history, and family history. The final response rate was high (93%) after three mailings and supplemental field visits. As a preliminary analysis, the distribution of these variables was compared by city and exposure status. This analysis revealed that Hiroshima subjects were more educated, were more often managers, clerical workers, and sales workers, performed less physical activity, had more living space and ate a more Western type diet than Nagasaki subjects. It was also shown that the distribution of such variables as place of birth, present address, occupation, marital status, and education differed by the exposure status of subjects. Some methodological problems inherent in a mail survey such as completeness and reliability of obtained information were discussed. 15 references, 1 figure, 28 tables.

Rediscovery of an old article reporting that the area around the epicenter in Hiroshima was heavily contaminated with residual radiation, indicating that exposure doses of A-bomb survivors were largely underestimated

International Nuclear Information System (INIS)

Sutou, Shizuyo

2017-01-01

The A-bomb blast released a huge amount of energy: thermal radiation (35%), blast energy (50%), and nuclear radiation (15%). Of the 15%, 5% was initial radiation released within 30 s and 10% was residual radiation, the majority of which was fallout. Exposure doses of hibakusha (A-bomb survivors) were estimated solely on the basis of the initial radiation. The effects of the residual radiation on hibakusha have been considered controversial; some groups assert that the residual radiation was negligible, but others refute that assertion. I recently discovered a six-decade-old article written in Japanese by a medical doctor, Gensaku Obo, from Hiroshima City. This article clearly indicates that the area around the epicenter in Hiroshima was heavily contaminated with residual radiation. It reports that non-hibakusha who entered Hiroshima soon after the blast suffered from severe acute radiation sickness, including burns, external injuries, fever, diarrhea, skin bleeding, sore throat and loss of hair—as if they were real hibakusha. This means that (i) some of those who entered Hiroshima in the early days after the blast could be regarded as indirect hibakusha; (ii) ‘in-the-city-control’ people in the Life Span Study (LSS) must have been irradiated more or less from residual radiation and could not function properly as the negative control; (iii) exposure doses of hibakusha were largely underestimated; and (iv) cancer risk in the LSS was largely overestimated. Obo's article is very important to understand the health effects of A-bombs so that the essence of it is translated from Japanese to English with the permission of the publisher.

Subjects who were exposed in utero to the atomic bombs in Hiroshima and Nagasaki, along with suitable controls, are examined annually at ABCC. Of the 1613 subjects in the study sample, 30 have gross mental retardation. Within 1500 m from the hypocenter the prevalence of mental retardation is 5 times as high as for the more distal subjects, and 6 to 15 weeks gestation was the most sensitive period. Even when subjects with possible explanations for their retardation are excluded the pattern of differences remains the same. All but two of the retarded subjects had a smaller than average head and for those who were within 1500 m this effect is accentuated. 17 references, 2 figures, 8 tables.

Effect on intelligence test score of prenatal exposure to ionizing radiation in Hiroshima and Nagasaki

Analyses of intelligence test scores (Koga) at 10-11 years of age of individuals exposed prenatally to the atomic bombing of Hiroshima and Nagasaki using estimates of the uterine absorbed dose based on the recently introduced system of dosimetry, the Dosimetry System 1986 (DS86), reveal the following: 1) there is no evidence of a radiation-related effect on intelligence among those individuals exposed within 0-7 weeks after fertilization or in the 26th or subsequent weeks; 2) for individuals exposed at 8-15 weeks after fertilization, and to a lesser extent those exposed at 16-25 weeks, the mean tests scores but not the variances are significantly heterogeneous among exposure categories; 3) the cumulative distribution of test scores suggests a progressive shift downwards in individual scores with increasing exposure; and 4) within the group most sensitive to the occurrence of clinically recognizable severe mental retardation, individuals exposed 8 through 15 weeks after fertilization, the regression of intelligence score on estimated DS86 uterine absorbed dose is more linear than with T65DR fetal dose, the diminution in intelligence score under the linear model is 21-29 points at 1Gy. The effect is somewhat greater when the controls receiving less than 0.01 Gy are excluded, 24-33 points at 1 Gy. These findings are discussed in the light of the earlier analysis of the frequency of occurrence of mental retardation among the prenatally exposed survivors of the A-bombing of Hiroshima and Nagasaki. It is suggested that both are the consequences of the same underlying biological process or processes. (author)

Education for hydraulics and pnuematics in Department of Computer Science, Faculty of Information Sciences, Hiroshima City University; Hiroshima shiritsudaigaku ni okeru yukuatsu kyoiku

Described herein is education of hydraulics and pneumatics in Hiroshima City University. Department of Computer Science is responsible for the education, covering a wide educational range from basics of information processing methodology to application of mathematical procedures. This university provides no subject directly related to hydraulics and pneumatics, which, however, can be studied by the courses of control engineering or modern control theories. These themes are taken up for graduation theses for bachelors and masters; 2 for dynamic characteristics of pneumatic cylinders, and one for pneumatic circuit simulation. Images of the terms hydraulics and pneumatics are outdated for students of information-related departments. Hydraulics and pneumatics are being forced to rapidly change, like other branches of science, and it may be time to make a drastic change from hardware to software, because their developments have been excessively oriented to hardware. It is needless to say that they are based on hardware, but it may be worthy of drastically changing these branches of science by establishing virtual fluid power systems. It is also proposed to introduce the modern multi-media techniques into the education of hydraulics and pneumatics. (NEDO)

1989-09-01

Associations of smoking habit with serum levels of total protein as well as protein fractions were studied in a population consisting of 4,739 atomic bomb survivors and unexposed control subjects in Hiroshima who participated in the 1979-81 period of the Adult Health Study, an on-going health follow-up program of the RERF. Smoking was strongly related to serum protein concentration after correction for age, sex, and body mass index. Among current smokers as compared to nonsmokers, levels of total protein, β globulin, and γ globulin were significantly lower (p 1 and α 2 globulin were significantly higher (p 1 globulin. Duration of smoking (years) was related to increased α 1 and α 2 globulin. Smoking duration was also associated with albumin level but the trend was not monotonic. The radiation exposure effect on serum protein level was significant in several instances but was in general much smaller than the smoking effect. Its inclusion in the regression models did not noticeably affect the association between smoking and serum proteins. (author)

1987-01-01

In order to elucidate the biological characteristics of colorectal cancer among atomic bomb survivors in Hiroshima, a total of 159 cases of colorectal cancers comprising 73 cases in exposed atomic bomb survivors and 86 cases in non-exposed individuals were examined histologically and immunohistochemically for various functioning proteins. No statistical differences could be demonstrated in the incidence of various marker expressions of colorectal cancers between the exposed group and control group. However, comparison by the site of colorectal cancer showed that sigmoid colon cancers in the exposed group or high dose group showed a significantly higher frequency of glycoproteins such as α 1 -antichymotrypsin (ACT), secretory component (SC), α 1 -antitrypsin (AAT), and human chorionic gonadotropin (HCG) when compared with the control group. These results correlated well with the epidemiological data that the radiation effect on the incidence of colorectal cancer in atomic bomb survivors was most remarkable in the sigmoid colon.

The instrumentation and control system for the research reactor in Research Reactor Institute, Kyoto University has been used for the safe and steady operation since the initial critical attainment in 1964. It has been modified and added many devices in the chance of increasing the reactor power from 1 MW to 5 MW, installing new experimental facilities or fitting to modified nuclear regulations. In order to avoid the unscheduled shutdown of the research reactor by cause the failure of the devices, most of instrumentation system was renewed in 1999. Operating the research reactor more safely and reliably, Supervisory Control Automation and Data Acquisition System which employed personal computers with the Windows NT operating system was added to the conventional instrumentation system, and the fieldbus system called Foundation Fieldbus was installed. Compared with conventional instrumentation system, each fieldbus system has some advantages. Many kinds of fieldbus systems have been developed and sold on the markets in some countries. Foundation Fieldbus standardizing international, which was able to use the devices made by multi-vendor was tentatively installed to study particular techniques about Foundation Fieldbus. The primary coolant flow rate, the temperature difference between the reactor tank inlet and outlet temperatures, the calorimetric power and the reactor power in nuclear instrumentation are monitored on human-machine interface devices on the fieldbus. The programmable logic controller is employed to control the information system for the reactor. This paper introduces Foundation Fieldbus installed. (author)

Self-Determination Theory as a Foundation for Personality Researchers.

Science.gov (United States)

Sheldon, Kennon M; Prentice, Mike

2017-11-16

In this introductory article we first describe the impetus for this special issue. What made us think that Self-Determination Theory (SDT) might provide a sort of foundation for the rest of personality psychology? For readers unfamiliar with SDT, we then provide a historical overview which covers the evolution of the six "mini-theories" that currently comprise SDT: cognitive evaluation theory, causality orientations theory, organismic integration theory, basic psychological needs theory, goal contents theory, and relational motivation theory. Following each section are preliminary suggestions about how each mini-theory might be useful or informative in other branches of personality. This special issue contains 9 articles, each of which makes its own attempt to newly link its area of personality research to SDT. Even if SDT is not the appropriate seed for greater consilience in personality psychology, we urge the field not to neglect the search for unifying principles (Sheldon, Chen, & Hilpert, 2011); it may finally be time to renew the search for a "grand theory" in personality.

Funding for biomedical and neuroscience research has increased over the last decade but without a concomitant increase in new therapies. This study's objectives were to determine the level and principal sources of recent funding for Parkinson disease (PD) research and to determine the current state of PD drug development. We determined the level and principal sources of recent funding for PD research from the following sources: US federal agencies, large PD foundations based in the United States, and global industry. We assessed the status of PD drug development through the use of a proprietary drug pipeline database. Funding for PD research from the sources examined was approximately $1.1 billion in 2003 and $1.2 billion in 2005. Industry accounted for 77% of support from 2003 to 2005. The number of drugs in development for PD increased from 67 in 2003 to 97 in 2007. Of the companies with at least one compound in development for PD in 2007, most were small (62% had annual revenue of less than $100 million), and most (53%) were based outside the United States. These companies will likely require partnerships to drive successful development of new PD therapies.

Swarm slide - debris flow disaster induced by extreme rainfall in Hiroshima, August 2014 and lessons learnt in urban designing

Science.gov (United States)

Fukuoka, H.; Wang, C.

2015-12-01

Hiroshima city was hit by swarm debris flows along a narrow, and linear-shaped rain band of 2 km x 10 km which appeared in the early morning of August 20, 2014. Most of the flows were induced by shallow slide in the upstream. This disaster claimed 74 death, although this city experienced very similar disaster in 1999, claiming more than 30 residents lives. In the most severely affected debris flow torrent, more than 50 residents were killed. Most of the casualties arose in the wooden, vulnerable houses constructed in front of the exit of torrents. Points and lessons learnt from the disaster are as follows:1. Authors collected two types of sands from the source scar of the initial debris slides which induced debris flows. Tested by the ring shear apparatus under pore-pressure control condition, clear "Sliding surface liquefaction" was confirmed for both samples even under small normal stress, representing the small thickness of the slides. These results shows even instant excess pore pressure could initiate the slides and trigger slide-induced debris flow byundrained loading onto the torrent deposits.2. Apparently long-term land-use change since 1945 affected and raised the vulnerability of the community. Residential area had expanded into hill-slope (mountainous / semi-mountainous area) especially along the torrents. Those communities were developed on the past debris flow fan.3. As the devastated area is very close to downtown of Hiroshima city, it gave large societal impact to the Japanese citizens. After 1999 Hiroshima debris flow disaster, the Landslide disaster reduction law which intends to promote designation of landslide potential risk zones, was adopted in 2000. Immediately after 2014 disaster, national diet approved revision of the bill to promote rapid completion of the designation over the national territory. MLIT (Ministry of Land, Infrastructure, Tranportation and Tourism) decided to install X-band rain radars at more sites to cover whole city zones

Leukemia in Hiroshima atomic bomb survivors

1959-03-01

This report is intended to provide the basic data pertinent to the leukemia experience observed in the survivors of the Hiroshima atomic explosion. Many of the conclusions in this report are tentative. The one clear fact to emerge is that radiation increases the occurrence rate of leukemia and that the magnitude of increase is dependent on dose received. Additional observations can be made, which, while not definitive in themselves, seem to complement each other, and are corroborated by other experiences in radiation biology. From the data a linear relationship between dose and incidence of leukemia is found. The shape of the relation in the lower dose range is not known with certainty. An approximate minimum time for the appearance of leukemia following radiation is 3 years or less. The data suggest that the time of maximum risk of leukemia may be dependent on the dose of radiation received. In this group the mean latent period is found to lie in the interval between 4 and 8 years following exposure. The length of time during which the increased incidence of leukemia persists is not known. The incidence of the acute leukemias and of chronic granulocytic leukemia is increased in the exposed survivors. The chronic granulocytic variety is disproportionately increased in Japanese survivors of the atomic bomb. No effect of radiation on monocytic or chronic lymphatic leukemia incidence is noted. Aplastic anemia, polycythemia vera, and myelofibrosis have been investigated. Myelofibrosis is the only one of this group of diseases in which a suggestive relation to radiation exposure is apparent. The natural history of leukemia following radiation does not seem to differ from that of the spontaneously occurring variety. 17 references, 5 figures, 38 tables.

Aging in Hiroshima and Nagasaki atomic bomb survivors: soluble--insoluble collagen ratio

Energy Technology Data Exchange (ETDEWEB)

Anderson, R E; Yamamoto, T; Thorslund, T W

1973-01-01

The soluble--insoluble collagen ratio was determined in aortas removed at autopsy during the period 1966--70 (21--25 years post-exposure); 261 specimens were examined from persons of both sexes, age 30--89 years at death. A portion of the test samples were from persons located less than 1500 m from the hypocenter at the time of the bomb. The ratio in this group was not significantly different from persons who were not in Hiroshima and Nagasaki at the time of the explosions. However, a possible discrepancy was noted between the two exposure groups involving both males and females who were less than 60 years of age at the time of death with lower average values among the exposed groups. This observation is interpreted and related to the pronounced life-shortening effect of radiation when animals are exposed at a young age. (DLC)

Radiation exposure and disease questionnaires of early entrants after the Hiroshima bombing

2012-01-01

It is popularly known that people who entered into the ground-zero area shortly after the atomic bombings in Hiroshima and Nagasaki suffered from various syndromes similar to acute radiation effects. External exposures from neutron-induced radionuclides in soil have recently been reassessed based on DS02 calculations as functions of both distance from the hypo-centres and elapsed time after the explosions. Significant exposure due to induced radiation can be determined for those who entered the area within 1000 m from the hypo-centres shortly after the bombing. Although it was impossible to track the action of each of the survivors over the days or weeks following the bombings in order to make reliable dose estimates for their exposures to soil activation or fallout, four individuals among those early entrants were investigated here to describe useful information of what happened shortly after the bombing.

Bone marrow aspiration smears obtained from 35 individuals, 5 years following exposure to the Hiroshima atomic bomb, were intensively evaluated for radiation related cytologic abnormalities. No definite radiation related changes were observed, but some findings were very suggestive. The most interesting of these was the occurrence of internuclear bridges joining erythroid precursors in the marrow smears of seven (20%) of the heavily exposed survivors. Although not specific it is likely that this lesion is indicative of residual stem cell damage and some degree of ineffectual erythropoiesis. The bone marrow morphologic lesions may be good markers of residual radiation damage but they are too infrequent in their occurrence to be of value as a biologic dosimeter. The findings in this study also suggest that a gradual disappearance of radiation induced late bone marrow changes continues for periods of 3 to 5 years or more following high dose acute radiation exposure.

ABCC-JNIH adult health study: Hiroshima. Serum lysozyme determinations, April-June 1961

Energy Technology Data Exchange (ETDEWEB)

Finch, S C; Lamphere, J P; Jablon, S

1961-01-01

Serum lysozyme levels were determined on 670 consecutive subjects seen for regularly scheduled clinic examinations of the Adult Health Study in Hiroshima. Serum lysozyme levels were found to vary significantly with the absolute peripheral granulocyte count, age, sex, and month of study. A high level of correlation also was noted between serum lysozyme and diabetes mellitus. This was at least in part attributable to greater average age in patients with diabetes. A suggestive relationship was established between serum lysozyme levels, respiratory diseases, and tuberculosis. These changes are believed to reflect active inflammation with excessive destruction of granulocytes and parenchymal tissues in those patients with the more acute processes. No relationship was found between serum lysozyme and previous exposure to ionizing radiation. These studies indicate that the serum lysozyme level may be useful in the study of the kinetics of leukopoiesis, the aging process, and in the detection of subtle inflammatory processes.

Pile foundation is widely used in construction and building marine structures. This is because pile foundation is an important structure and should have long-term durability. However, in waterfront development, a lot of issues from the seawater should be considered distinctively because it consists of many problems that can affect the building structure especially the foundation of the building. Thus, a research should be conducted to identify issues of pile foundation at waterfront development and determine its prevention methods. The research was carried out through interviews with the developers and contractors from the projects of Lexis Hibiscus at Port Dickson, Negeri Sembilan and Redevelopment for Deep-Water Facilities at Quay 6 in Pasir Gudang, Johor, Malaysia. The objectives of this research are to identify issues of pile foundation and to determine the prevention methods of pile foundation issues at waterfront development. All respondents agreed that the main issues of pile foundations at waterfront development are the wave and tide condition. The prevention methods of the issue faced at waterfront development that are most frequently used for the pile foundation are coating system and concrete cover. This research is beneficial to all developers and contractors to ensure pile foundations at waterfront development can be protected by using the prevention methods.

Radiation therapy among A-bomb survivors, Hiroshima and Nagasaki

Energy Technology Data Exchange (ETDEWEB)

Russell, W J; Antoku, S

1971-01-01

The hospitals and clinics responsible for radiation therapy reported by ABCC-JNIH Adult Health Study subjects were surveyed to confirm treatment and estimate doses they received. Of 426 cases, 137 were documented by hospital records. Their ABCC medical records were also reviewed for pertinent clinical information. Excluding the cases not verified because of unavailability of records, confirmation rates were 0.46 in Hiroshima and 0.67 in Nagasaki. Radiation therapy doses according to date of treatment, diagnosis, body site, and source of exposure are included. These data are recorded routinely for future reference, along with doses from diagnostic roentgenology for evaluating overall ionizing radiation exposure of A-bomb survivors and their comparison subjects. Radiation therapy by source and by lesion treated is included. There were three cases with malignancies possibly related to their earlier radiation therapy. One was an A-bomb survivor with lung cancer previously reported as due to ionizing radiation from the A-bomb. Radiation therapy she received for breast cancer 11 years earlier was more likely the cause of the lung lesion than was her relatively small A-bomb dose. The importance of recording all diagnostic and therapeutic radiation, especially that received by those under continuing surveillance for late A-bomb effects, is stressed. (auth)

The purpose of this study was to review outcomes of the Oral and Maxillofacial Surgery (OMS) Foundation's funding awards to members of the OMS department at Massachusetts General Hospital (MGH) in terms of projects completed, abstracts presented, peer-reviewed publications, and career trajectories of recipients. Data were collected from MGH and OMS Foundation records and interviews with award recipients. Primary outcome variables included 1) number of awards and award types, 2) funding amount, 3) project completion, 4) number of presented abstracts, 5) conversion from abstracts to publications, 6) number of peer-reviewed publications, 7) career trajectories of awardees, and 8) additional extramural funding. Eleven Student Research Training Awards provided $135,000 for 39 projects conducted by 37 students. Of these, 34 (87.2%) were completed. There were 30 student abstracts presented, 21 peer-reviewed publications, and a publication conversion rate of 58.8%. Faculty research awards comprised $1,510,970 for 22 research projects by 12 faculty members and two research fellows. Of the 22 funded projects, 21 (95.5%) were completed. There were 110 faculty and research fellow abstracts presented and 113 peer-reviewed publications, for a publication conversion rate of 93.8%. In the student group, 17 of 37 (45.9%) are enrolled in or are applying for OMS residencies. Of the 10 students who have completed OMS training, 3 (30%) are in full-time academic positions. Of the 12 faculty recipients, 9 (75%) remain in OMS academic practice. During this time period, the department received $9.9 million of extramural foundation or National Institutes of Health funding directly or indirectly related to the OMS Foundation grants. The results of this study indicate that 90.2% of projects funded by the OMS Foundation have been completed. Most projects resulted in abstracts and publications in peer-reviewed journals. These grants encouraged students to pursue OMS careers and aided OMS

Measurement of radon concentration in water by means of {alpha}, {gamma} spectrometry. Radon concentration in ground and spring water in Hiroshima Prefecture

1997-02-01

Radon ({sup 222}Rn, T{sub 1/2}=3.8235{+-}0.0003d) is {alpha}-ray releasing nuclide, so that it can not be detected by {gamma}-ray measurement. But, the daughter nuclides {sup 214}Pb (T{sub 1/2}=26.8 min) and {sup 214}Bi (T{sub 1/2}=19.9 min) release {gamma}-ray, accordingly they are measured by Ge detector. Their radioactive equilibrium is kept in the closed vessel, because their half-lives are shorter than that of radon. We developed a measurement method of radon concentration by means of {gamma}-spectrometry. We applied this method to catch radon in the atmosphere by active carbon. The same principle can be applied to radon in water. Radon concentrations in the ground water were measured in 22 points in the Higashi-Hiroshima city and 82 points in the Hiroshima prefecture. The efficiencies of {gamma}-ray were determined. The radon concentration showed between 11 and 459 Bq/l and the average was 123 Bq/l. The high concentration of radon was distributed in the spring of granitic layer and higher concentration of radon were observed in the ground water of fault. (S.Y.)

The Rheumatology Research Foundation's Clinician Scholar Educator (CSE) award is a 3-year career development award supporting medical education research while providing opportunities for mentorship and collaboration. Our objective was to document the individual and institutional impact of the award since its inception, as well as its promise to strengthen the subspecialty of rheumatology. All 60 CSE Award recipients were surveyed periodically. Fifty-six of those 60 awardees (90%) responded to requests for survey information that included post-award activities, promotions, and further funding. Data were also collected from yearly written progress reports for each grant. Of the total CSE recipients to date, 48 of 60 (80%) are adult rheumatologists, 11 of 60 (18%) are pediatric rheumatologists, and 1 is an adult and pediatric rheumatologist. Two-thirds of survey respondents spend up to 30% of their total time in educational activities, and one-third spend greater than 30%. Thirty-one of the 60 CSE recipients (52%) have published a total of 86 medical education papers. Twenty-six of 52 (50%) had received an academic promotion following the award. Eleven awardees earned advanced degrees. We describe the creation and evolution of a grant program from a medical subspecialty society foundation and the impact on producing education research, individual identity formation, and ongoing support for educators. This community of rheumatology scholar educators now serves as an important resource at the national level for the American College of Rheumatology and its membership. We believe that this grant may serve as a model for other medical societies that want to promote education scholarship and leadership within their specialties. © 2016, American College of Rheumatology.

ABCC-JNIH adult health study Hiroshima and Nagasaki 1961 exposure to medical x-ray. Preliminary survey

Energy Technology Data Exchange (ETDEWEB)

Ishimaru, Toranosuke; Russell, W J

1962-05-16

A survey was conducted for three months among subjects seen in the medical clinics of ABCC, Hiroshima and Nagasaki, to determine the extent of medical x-ray received in ABCC and other hospitals and clinics. Emphasis was chiefly methodological to prepare for later studies designed to evaluate the contribution of medical x-ray to total radiation dose received by survivors of the atomic bombings and controls. The frequency, the institution in which the subject received x-ray, as well as the types of exposure were the prime considerations in the survey. The data were analyzed for each city by sex, age, and exposure status. 2 references, 5 figures, 11 tables.

Data are presented on the sex ratio of 47,624 children born in Hiroshima and Nagasaki during 1956 to 1962. The total number of births in these two cities for which information is available is now 140,542, and of this number in 73,994 instances one or both parents were exposed to the atomic bombs. The suggestion of an effect of exposure on sex ratio in the earlier data is not borne out by the present findings. One can argue either that a small early effect has disappeared or that the original observation had no biological significance. 27 references, 4 tables.

While there is a considerable number of studies on the relationship between the risk of disease or death and direct exposure from the atomic bomb in Hiroshima, the risk for indirect exposure caused by residual radioactivity has not yet been fully evaluated. One of the reasons is that risk assessments have utilized estimated radiation doses, but that it is difficult to estimate indirect exposure. To evaluate risks for other causes, including indirect radiation exposure, as well as direct exposure, a statistical method is described here that evaluates risk with respect to individual location at the time of atomic bomb exposure instead of radiation dose. In addition, it is also considered to split the risks into separate risks due to direct exposure and other causes using radiation dose. The proposed method is applied to a cohort study of Hiroshima atomic bomb survivors. The resultant contour map suggests that the region west to the hypocenter has a higher risk compared to other areas. This in turn suggests that there exists an impact on risk that cannot be explained by direct exposure. (orig.)

1980-02-01

An analysis was made of the relationship of radiation dose to the occurrence of primary intracranial tumors among atomic bomb survivors and nonexposed controls, Hiroshima and Nagasaki, in the fixed cohort of the Life Span Study (LSS) extended sample during the period 1961-75, or 16 to 30 years after the A-bombs. Based on various medical sources, 104 cases of primary intracranial tumors were identified among approximately 99,000 LSS extended sample members who were alive as of 1 January 1961. Of these 104 cases, 45 had manifested clinical signs of brain tumors, but, 59 cases were identified incidentally at postmortem examination. The distributions of morphologic type, age, and size of tumor were quite different for those primary intracranial tumors with and without a clinical sign of brain tumor. Glioma was the most frequent type of tumor with a clinical sign and meningioma was the most frequent type without. In relation to radiation dose the incidence rate of primary intracranial tumors with a clinical sign showed a significant excess risk for males in the high dose group who received 100 rad or more after adjustment for age at the time of the bomb (ATB). The standardized relative risk is around 5 in this group. The data also suggest that the crude relative risk of glioma is greater in the high dose group for younger ages ATB. However, there is no increased risk in females. Among the 5,012 autopsy subjects in the LSS extended sample during 1961-75, there is no relationship between radiation dose and the prevalence rate of primary intracranial tumors in those identified incidentally by autopsy. The relative risk of subclinical adenoma of the pituitary gland between high dose subjects and controls was also examined for a sample of 95 sex- and age-matched pairs using Hiroshima autopsy materials for 1961-74, but no relationship to dose was observed.

1989-01-01

Data on a total of 7,593 persons in Hiroshima who were in 2,518 wooden Japanese houses and exposed to A-bomb within 1.6 km from the hypocenter have been used to estimate the LD 50/60 . The effect of radiation shielding for these people in particularly well-characterized in the new dosimetry system DS86. A range of values emerge, varying slightly with the method of estimation used. This range, derived from DS86 marrow doses, and based on a linear fit to equally weighted estimates of the probabilities of death at various doses, is 2.3-2.6 Gy. A linear estimate in which the probabilities of death at the various doses are weighted by the inverse of their variances is somewhat lower, 2.2 Gy. These values may be underestimates of actual LD 50/60 because of inclusion of deaths in the first day, and the severely injured (burns, trauma) who survived the first day but succumbed later to their injuries.

A group of pathologists from the United States and Japan reviewed breast cancer material of women exposed to the atomic bombs in Hiroshima and Nagasaki and controls. The purpose of the review was to verify the diagnoses, establish a base of confirmed cases for epidemiologic study, and provide a reference for other pathology review. Compared to the control group, matched through the Life Span Study extended sample, there were no differences in distribution of tumor type and tumor size. There were also no differences in histological type by age or radiation dose. The peak age for cancer to develop was the same in the exposed and control groups. The type of radiation had no effect on histological type. Atypical changes or residual proliferative lesions were not found in women exposed to radiation but free from cancer. On the basis of this study, it was concluded that radiogenic breast cancer does not differ histologically from spontaneously occurring cancer in Japanese women. (author)

Full Text Available Ambient levels of formaldehyde (HCHO and acetaldehyde (CH3CHO were measured at Hiroshima (Japan during spring and summer of 2005. Measurements of O3, NOx, and SO2 were simultaneously conducted, in an attempt to identify temporal profiles and sources for these aldehydes. Atmospheric aldehydes were collected using C18 silica gel cartridges coated with an acidic solution of 2, 4-dinitrophenylhydrazine (2,4-DNPH and analyzed by high performance liquid chromatography with UV/VIS detection adjusted to 360 nm. Summer concentrations were higher than spring levels. FA concentrations during spring period ranged from 0.50 to 1.05 ppb and AA concentrations ranged from 0.17 to 1.31 ppb; during summer their concentrations ranged from 1.55 to 4.12 ppb and 0. 34 to 2.03 ppb. Average FA/AA in spring and summer were 3.09 and 3.72 suggesting biogenic emissions of aldehydes. The levels of FA and AA, their temporal variations, and their concentration ratio (FA/AA indicated that photochemical reactions contributed significantly to the formation of atmospheric aldehydes at the study site.

Simulation-based mastery learning (SBML), like all education interventions, has learning theory foundations. Recognition and comprehension of SBML learning theory foundations are essential for thoughtful education program development, research, and scholarship. We begin with a description of SBML followed by a section on the importance of learning theory foundations to shape and direct SBML education and research. We then discuss three principal learning theory conceptual frameworks that are associated with SBML-behavioral, constructivist, social cognitive-and their contributions to SBML thought and practice. We then discuss how the three learning theory frameworks converge in the course of planning, conducting, and evaluating SBML education programs in the health professions. Convergence of these learning theory frameworks is illustrated by a description of an SBML education and research program in advanced cardiac life support. We conclude with a brief coda.

Beginning within a few weeks after the bombings and periodically during the intervening decades, investigators in Hiroshima and Nagasaki have collected samples of materials that were in the cities at the time of the bombings. Although some early efforts were not driven by specific measurement objectives, many others were. Even some of the very earliest samples collected in 1945 were based on carefully conceived research plans and detailed specifications for samples appropriate to particular retrospective measurements, i.e., of particular residual quantities remaining from exposure to the neutrons and gamma rays from the bombs. This chapter focuses mainly on the work of groups at two institutions that have actively collaborated since the 1980s in major collection efforts and have shared samples among themselves and with other investigators: the Radiation Effects Research Foundation (RERF) and its predecessor the Atomic Bomb Casualty Commission (ABCC), and Hiroshima University. In addition, a number of others are listed, who also contributed to the literature by their collection of samples. (J.P.N.)

The Research on Subsidence Prediction of Soils Around Deep Foundation Pit

Directory of Open Access Journals (Sweden)

Ge LIU

2014-12-01

Full Text Available Deep foundation pit will cause settlement of surround buildings in the process of excavation. When the settlement is excessive, it will give rise to safety issues. Subsidence monitoring has become an important measure to ensure the safety of deep foundation pits. But in current subsidence monitoring engineering, the costs of wiring, unwiring and installation are particularly high. This paper proposes a portable wireless data transmission device in forecasting and early warning of settlement deformation of soils around deep foundation pits. We solve the problem by adopting the means of wireless communication to replace the cable transmission link part. The device does not rely on any personal computers. Instead, it can directly deal with the collected data through grey prediction GM (1, 1 mathematical model, neural network and interpolation model to give short-term, medium- term and long-term forecasts, respectively. Additionally it is able to set a threshold value. Once the forecast data reach the threshold, the device can issue alert and achieve the target of reminding technicians, so as to provide reliable basis to prevent and reduce disasters.

Photography and nuclear catastrophe. The visual representation of the occurrences in Hiroshima/Nagasaki and Chernobyl; Fotografie und atomare Katastrophe. Die visuelle Repraesentation der Ereignisse von Hiroshima/Nagasaki und Tschernobyl

Energy Technology Data Exchange (ETDEWEB)

Buerkner, Daniel

2014-02-13

The dissertation project seeks to analyse the photographic positions that deal with the atomic bomb attacks on Hiroshima and Nagasaki and the accident of the nuclear power plant in Chernobyl. This focus includes press photographs of the events as well as artistic, documentary and touristic images that take an approach towards the disasters often years after and hereby form iconographic or material references to the events. The study reveals central strategies for photographic images of atomic catastrophes, be they of military or civil nature. It is the inability to visualize non-visible nuclear rays or the complexity of processes on an atomic level that has turned out to be crucial. This incapacity of making images, a paradigm of invisibility, substantially coins the cultural role of the events. The question of how a society deals with these abstract potentials of nuclear technology has turned out to be always anew of high relevance in regard to ecological, social and technological policies of images.

Governance of Open Source Software Foundations: Who Holds the Power?

Directory of Open Access Journals (Sweden)

Ludovico Prattico

2012-12-01

Full Text Available The research reported in this article attempts to discover who holds the power in open source software foundations through the analysis of governance documents. Artificial neural network analysis is used to analyse the content of the bylaws of six open source foundations (Apache, Eclipse, GNOME, Plone, Python, and SPI for the purpose of identifying power structures. Results of the research suggest that: i the actions of an open source software foundation are centered around one of three groups: Members, Chairman/President/Executive Director, and Board of Directors; ii in only one of the six foundations is the Board of Directors responsible for both the community and the product; and iii artificial neural network analysis of the content of bylaws provides unbiased insights of the power structure of open source software foundations. These results may prove useful to those who contribute to open source foundations and use their products and services.

The foundation of self-esteem.

Science.gov (United States)

Bailey, Joseph A

2003-05-01

Self-esteem is a simplistic term for varied and complex mental states pertaining to how one views oneself. It takes but little research in the voluminous literature to see the vagueness and inconsistencies in its various definitions. Even more problematic is the uncertainty concerning its foundational components. The importance of having a solid definition and specific ideas about the foundational components of self-esteem is that both pave the way to recognizing its causes; to predicting effects from those causes; and to organizing the trouble-shooting process for locating those philosophical flaws or psychological scars which lead to low self-esteem. The purpose of this paper is to offer a common ground for thinking about self-esteem at its most basic level. In order to distinguish the "basic level" from the rest of the components of self-esteem, let us liken it to a skyscraper building. Here, the focus is on the building's "underground foundation" and the base upon which that foundation rests. The base is a definition that allows for the assessment of the foundation. The underground foundation itself consists of the mental building blocks called self-meaning, self-identity, self-image, and self-concepts. To help illustrate their interactions, a few of the "masks" and "faces" of self-esteem will be mentioned. What is not being addressed is the "above ground structure"--those theories and manifestations dealt with by most mental health specialists.

Hospital and clinic survey estimates of medical X-ray exposure in Hiroshima and Nagasaki, 2

The technical factors used during radiological examinations performed in Hiroshima and Nagasaki medical institutions were analyzed. The most frequently performed examination was chest radiography, followed by upper GI series. More than half the radiographic exposures were from upper GI series due to the many spot films made during fluoroscopy. Comparison of the present survey results with those of a previous one showed that relatively high kVp, low mAs and mA, and smaller field sizes are now more widely used. Though there have been decreased in fluoroscopy times and tube currents over the past 10 years, the numbers of spot films used have increased. Based on these technical factors, tables of organ doses from fluoroscopic examinations were compiled. (author)

The effect of ionizing radiation on immune system

International Nuclear Information System (INIS)

Gyuleva, I.

1999-01-01

Delayed radiation effects of irradiation at relatively high doses - 0.52- 2 Gy in result of severe accidents are discussed. The immune response of lymphocyte populations manifested in formation of different kind of mutant cells at Hiroshima-A-bombing and Chernobyl accident are presented. It is of great interest the hypothesis presented launched by RERF (Japanese Foundation for Radiation Effect Research, Hiroshima) for radiation induced predominant of T H2 -lymphocytes in comparison to T H1 as delayed immune response at the Hiroshima-A-bomb survivors. The aspect of immune status is quite different at low doses irradiation (0.02 - 0.2 Gy). There is some stimulation in immune response known as hormesis effect. It is suggested that T-cell activation has key role in immune system stimulation at doses under 0.2 Gy. There is also activation of DNA-reparation mechanisms. Suppression of the hypothalamus-hypophysis-suprarenal axis brings to enhancing of immune potential. Chinese people living in a region with three-times higher background radiation, X-ray examined patients as well as occupationally exposed personnel have been investigated. Radioprotective effect of some cytokines and their influence on the individual radiosensitivity are also discussed.The investigations have to be continued because of some inconsistent results

The Radiation Effects Research Foundation maintains a database containing detailed information on every known measurement of environmental materials in the cities of Hiroshima and Nagasaki for gamma-ray thermoluminescence or neutron activation produced by incident radiation from the atomic bomb detonations. The intent was to create a single information resource that would consistently document, as completely as possible in each case, a standard array of data for every known measurement. This database provides a uniquely comprehensive and carefully designed reference for the dosimetry reassessment. (J.P.N.)

RESEARCH OF THE FOUNDATION CONSOLIDATED BY DIFFERENT-SIZED HORIZONTAL ELEMENTS

Directory of Open Access Journals (Sweden)

Isakova Elena Aleksandrovna

2016-05-01

Full Text Available The article is dedicated to the problem of geotechnics. The problems of the weak soil base are topical. Also there sometimes happen severe accidents of soil mass. A great number of such emergencies is of a progressive character, when a local crash leads to the crash of the whole construction. Tarring the soil with epoxy can ensure geotechnical safety of the basis. That’s why the improvement of this method is needed in order to reduce yielding of the base, create ground water cutoff or create building hoisting. In the article new structural solutions for reduction of settlement are presented. The authors suggest using the manufactured plane elements containing epoxy. Such elements have different sizes and lie underneath the foundation. Similar structural scheme can be used to reduce soil settlement. The authors carried out two series of plate-bearing model tests with manufactured plane epoxy elements. In the first series of tests the biggest element was closer to the foundation, the smallest element was closer to the biggest element. In the second series of tests the smallest element was closer to the foundation, the biggest element was closer to the smallest element. After the end of plate-bearing model tests the authors received values of the base settlement and the dependency diagrams “base settlement-soil pressure”. The new structural solution for reducing soil settlement proved to be effective. Settlement of base decreased sevenfold.

The application of business models to medical research: interviews with two founders of directed-philanthropy foundations. Interview with Scott Johnson and Don Listwin by Kathryn A. Phillips.

A new trend in research funding has emerged: directed philanthropy, in which the donor plays an active, hands-on role in managing the research by applying a "business model." Although such efforts now represent only a small portion of foundation funding, they have potentially far-reaching implications because (1) the approach of using a business model is being applied more broadly and (2) the success or failure of these efforts may portend the fate of larger translational efforts. The author conducted interviews with Scott Johnson of the Myelin Repair Foundation and Don Listwin of the Canary Foundation in the fall of 2006.

Research on horizontal displacement monitoring method of deep foundation pit based on laser projecting sensing technology

Science.gov (United States)

Liu, Peng; Xie, Shulin; Zhang, Lixiao; Zhou, Guangyi; Zhao, Xuefeng

2018-03-01

A certain level of horizontal displacement will occur during excavation or subsequent construction of deep foundation pit. If the support is improper and the horizontal displacement of the foundation pit is too large, it will cause collapse and even affect the buildings around the foundation pit, which will endanger people's life and property. Therefore, the horizontal displacement monitoring of deep foundation pit becomes more and more important. At present, the electronic total station is often used to monitor the horizontal displacement of the foundation pit, but this monitoring method is expensive, prone to accidental errors, and can not be used for real-time monitoring. Therefore, a method of monitoring the horizontal displacement of deep foundation pit by using laser projection sensing technique is proposed in this paper. The horizontal displacement of the foundation pit is replaced by the displacement of the laser spot emitted by the laser, and the horizontal displacement of the foundation pit can be obtained by identifying the displacement of the laser spot projected on the screen. A series of experiments show that the accuracy of this monitoring method meets the engineering requirements and greatly reduces the cost, which provides a new technology for the displacement monitoring of deep foundation pit.

Boni, G.

2009-04-01

CIMA is a Research Foundation which aim is to advance science and engineering in environmentally related fields, focusing on public health and safety, civil protection and the preservation of terrestrial and water-related ecosystems. This aim is accomplished through scientific research, technology transfer and high level training services. Here we present the "New Aphrodite school on Disasters Food and Poverty" jointly managed by CIMA Foundation, and the University of Genova. The school is organized to provide to international students, professionals and government officials, mainly from poor or developing countries, formation for the management, prediction and prevention of natural and man made disasters. The expertise of the teachers, mainly CIMA's researchers, comes from a long term support of CIMA Foundation to the Italian Civil Protection in developing the advanced national system for risk prediction, prevention and management. The school is organized in two levels. The first level includes an international master of science degree in "Environmental Engineering: Sustainable Development and Risk Management", which classes are given in English, and a master for professional and government officials in "Disasters, food and poverty". The second level includes an international Ph.D. programme in "Information sciences and technologies for system monitoring and environmental risk management". Short training courses for international government official are periodically organized. At present the school is organizing short courses for officials of Civil Protections of Venezuela, Barbados and Mozambique. The philosophy underlying the teaching activities is to promote a multi-disciplinary approach to disaster mitigation, prevention and prediction. Special focus is on the potential of high-tech low-cost technologies for rapid communication and disaster monitoring, such as satellite based technologies. Such technologies are seen as the best way to support the development

Epidemiology of urinary tract infections in Hiroshima

Freedman, L R; Phair, J P; Seki, Masafumi; Hamilton, H B; Nefzger, M D

1964-08-19

The present study was conducted at ABCC on a sample of Hiroshima residents systematically seleced for determining the influence on general health status of exposure to the atomic bomb of 1945. A survey for urinary infections was taken on persons in the sample examined in the ABCC clinic over a 1-year period: approximately 3000 women and 2000 men. The purpose of the study was to determine the prevalence of urinary infection and to study the relation between bacteriuria and various aspects of the general examination, particularly blood pressure. In addition, the rates of urinary tract infection in the clinic were compared with the rates of chronic pyelonephritis at autopsy. Results showed that infections were much more common in women than in men and rose with age in both sexes. The greatest increase in the prevalence was found in women age 60 years and over was due to coliform bacteria in all but a few instances. There was no difference in hematuria, glycosuria, diabetes, serum cholesterol, blood groups, electrocardiograms, audiometry, vibrometry, hemoglobin levels or height-weight ratios. Blood pressure is higher in infected women as compared with noninfected women and the finding of higher rates for cardiac enlargement suggests that this small difference in blood pressures may have biological significance. However, the data do not permit a conclusion as to whether the urinary infections were responsible for the higher blood pressure levels, or whether the higher blood pressure levels increased the frequency of detectable infection. The difference between the clinical rates of urinary infection in men and women, and the pathological diagnosis of pyelonephritis in the same population, supports a previous suggestion that much of what is called pyelonephritis at autopsy is not due to urinary tract infection. 27 references, 2 figures, 10 tables.

Full Text Available In this paper a short review of the history of Alexander von Humboldt Foundation, Bonn - Bad Godesberg, Germany, on the occasion of its 60th anniversary is presented. This outstanding German foundation is actually the third one with the same name. Earlier two other Alexander von Humboldt Foundations consequently existed and they consist its pre-history, which is also shortly reviewed. The establishment of the present Foundation in 1953, its development and growth, its activities, information about the six presidents and five executive directors, as well as the main features, principles and guidelines are considered. During the last 60 years the Alexander von Humboldt Foundation became an important institution for the promotion of international research cooperation, which significantly influences the world science. It supported more than 27700 Humboldt fellows to carry out scientific research in Germany, and they form a large Humboldt family: a world-wide network. Large number Bulgarian Humboldt fellows are among the best scientists in Bulgaria.

There is a distinct shortage of preprofessional opportunities for undergraduate premedical students. During the last 7 summers, the Minneapolis Heart Institute Foundation Summer Research Internship Program has exposed interested students to cardiology and clinical research. The goals of the internship program are threefold: to bring students in contact with the medical profession, to offer experiences in the various disciplines of cardiology, and to introduce students to clinical research. The success of the program can be measured by its influence on participants' academic pursuits and scholarly contributions. Of the 65 internship alumni, 52 are studying to become physicians and most of the others are in health-related fields. Interns have also contributed abstracts and manuscripts to peer-reviewed journals and presented their research at major conferences.

ABCC-JNIH pathology studies: Hiroshima and Nagasaki. Report 1, October 1950-September 1962

Energy Technology Data Exchange (ETDEWEB)

Angevine, D M; Jablon, S; Matsumoto, Y S

1962-01-01

A sample of 100,000 persons in both Hiroshima and Nagasaki was constructed to serve as the basis for the JNIH-ABCC Life Span Study. A subsample of 20,000 is the basis for the ABCC-JNIH Adult Health Study. The third element, the pathology program was instituted to endow the autopsy program with the high degree of statistical control characterizing the Life Span and Adult Health studies. A study of the autopsy series (1215 cases) was made to: (1) determine how adequately the more recent cases meet the expectations with respect to age, sex, city, and distance from the hypocenter, and to determine whether any of the original bias still exists and if so, to what extent; (2) ascertain the degree of correlation between death certificate diagnoses and the autopsy anatomic diagnoses; and (3) determine what effect, if any, the degree of exposure to radiation may have had upon different disease groups, with special emphasis on various maligmant tumors.

1978-01-01

The authors examined 155 autopsy cases of Hashimoto's thyroiditis in the Life Span Study sample including both A-bomb survivors and controls in Hiroshima and Nagasaki (1954 to 1974). Hashimoto's thyroiditis was classified into lymphoid, diffuse and fibrous types and the following results were obtained. No difference existed in the effects of A-bomb radiation in the incidence and ATB (At the time of the A-bomb). The ration of males to females did not reveal statistical significance, even though reversed ratio was noted in the high dose group. The variation of thyroid gland weight in T65 dose or by variant showed no significant pattern, even though the smallest average weight was found in the highest radiation exposure group. The complication in the patients with Hashimoto's thyroiditis were noted to have high prevalance of ovarian cancer and low prevalence of stomach cancer and total cancer. Only two patients with Hashimoto's thyroiditis were found to be complicated with thyroid carcinoma. Among collagen diseases, the prevalence of rheumatic fever and rheumatoid arthritis was high as complication. And the prevance of combined diseases suggested that no late effect of A-bomb radiation existed. (author)

The author is continuing to observe socio-medically long-lived survivors over 90 years of age who are in the Hiroshima Survivors' Home, and this is the first report on them. In spite of a fairly large number of survivors of short-distance exposure, unexpectedly few showed a high dose. There were few medical findings suggestive of the effect of exposure. Although chronic diseases due to aging were observed prominently, no basis suggestive of the promotion of aging due to exposure was obtained. In view of social environments, born in rural districts, many of them tended to be rather unyielding and have endured low-income life, and their body had been hardened by physical labor. Most of them had rather mild somatic disturbances, and unexpectedly few needed complete help or diapers. Very few were judged to be DE by the ADL table. Of the total number of deaths (77) in 5 years, only 5 were above 90 years of age, and the cause was heart disease in 3 and senility in 2.

Correlations between tests of aging in Hiroshima subjects: an attempt to define physiologic age

Energy Technology Data Exchange (ETDEWEB)

Hollingsworth, J W; Hashizume, Asaji; Jablon, Seymour

1964-12-01

Nine physiologic functions which change with age were measured in 437 subjects during their regular visits to the Atomic Bomb Casualty Commission clinic in Hiroshima, Japan. This pilot study was undertaken to determine the feasibility of collecting such data in a population sample physiologic age score. Tests conducted consisted of: skin elasticity, systolic blood pressure, vital capacity, hand grip strength, light extinction time, vibrometer, visual activity, audiometry, and serum cholesterol. The study demonstrated that adequate sample data could be obtained, and that statistical treatment could construct a physiologic age for individual subjects. However, the tests were of limited value below age 40, and the validation of the concept of physiologic age requires eventual correlation with mortality. Since the ABCC program includes a highly accurate mortality survey, it is hoped that data on physiologic aging can be collected and eventually related to mortality. 11 references, 3 figures, 6 tables.

Eclecticism as the foundation of meta-theoretical, mixed methods and interdisciplinary research in social sciences.

Science.gov (United States)

Kroos, Karmo

2012-03-01

This article examines the value of "eclecticism" as the foundation of meta-theoretical, mixed methods and interdisciplinary research in social sciences. On the basis of the analysis of the historical background of the concept, it is first suggested that eclecticism-based theoretical scholarship in social sciences could benefit from the more systematic research method that has been developed for synthesizing theoretical works under the name metatheorizing. Second, it is suggested that the mixed methods community could base its research approach on philosophical eclecticism instead of pragmatism because the basic idea of eclecticism is much more in sync with the nature of the combined research tradition. Finally, the Kuhnian frame is used to support the argument for interdisciplinary research and, hence, eclecticism in social sciences (rather than making an argument against multiple paradigms). More particularly, it is suggested that integrating the different (inter)disciplinary traditions and schools into one is not necessarily desirable at all in social sciences because of the complexity and openness of the research field. If it is nevertheless attempted, experience in economics suggests that paradigmatic unification comes at a high price.

THE PHILOSOPHICAL FOUNDATIONS OF MODERN BIOENGINEERING

Directory of Open Access Journals (Sweden)

Ibrahim A. Shogar

2017-12-01

Full Text Available This paper investigates the philosophical foundations of modern bioengineering to articulate its ethical framework. Engineering as an ultimate mechanism to transform knowledge into practice is essential for both physical and biological sciences. It reduces data, concepts, and designs to pictorial forms. The integration of engineering with the newly emerging biosciences, has presented a unique opportunity to overcome the major challenges that face the environmental and human health. To harness potentials of bioengineering and establish a sustainable foundation for green technology, modern scientists and engineers need to be acquainted with the normative questions of science. In addition to acquiring the general principles of scientific research and identifying the intrinsic goals of the endeavour, philosophy of bioengineering exposes bioengineers to both the descriptive ‘how’ questions of the physical world as well as the normative ‘why’ questions of values. Such an interdisciplinary approach is significant, not only for inspiring to acquire the genuine knowledge of the existing world, but also to expose the bioengineers to their ethical and social responsibilities. Besides introducing the conceptual framework of bioengineering, this paper has investigated the three major philosophies that have been dominating the theoretical presuppositions of scientific research method in history. Namely, (i Systems biology approach; (ii Evolutionary biology approach; and (iii Mechanical view approach. To establish the ethical foundation of modern bioengineering, the paper, also has conducted an analytical study on various branches of the emerging discipline of bioscience. The paper has concluded that adopting the interdisciplinary approach in research and education is essential to harness potentials of bioengineering and to establish foundations of green technology. To achieve the final objectives of bioengineering, both the practical and theoretical

The origins of the research on the foundations of quantum mechanics (and other critical activities) in Italy during the 1970s

Baracca, Angelo; Bergia, Silvio; Del Santo, Flavio

2017-02-01

We present a reconstruction of the studies on the Foundations of Quantum Mechanics carried out in Italy at the turn of the 1960s. Actually, they preceded the revival of the interest of the American physicists towards the foundations of quantum mechanics around mid-1970s, recently reconstructed by David Kaiser in a book of 2011. An element common to both cases is the role played by the young generation, even though the respective motivations were quite different. In the US they reacted to research cuts after the war in Vietnam, and were inspired by the New Age mood. In Italy the dissatisfaction of the young generations was rooted in the student protests of 1968 and the subsequent labour and social fights, which challenged the role of scientists. The young generations of physicists searched for new scientific approaches and challenged their own scientific knowledge and role. The criticism to the foundations of quantum mechanics and the perspectives of submitting them to experimental tests were perceived as an innovative research field and this attitude was directly linked to the search for an innovative and radical approach in the history of science.

Energy Technology Data Exchange (ETDEWEB)

Skaar-Jacobsen, Anja [Niels Bohr Archive, Copenhagen (Germany)

2011-07-01

It is well-known that the cultural cold war changed the ideological line in the Soviet Union from the late 1940s and that this had serious implications for the autonomy of research in genetics and quantum foundations in the East bloc. However, besides the more narrow concern from the point of view of research in quantum foundations, I suggest that the ideological impact on quantum foundations also constituted an obstacle for attempts by Western physicists to bring about a rapprochement between physics in the east and west in general. In connection with re-establishing East-West co-operation between physicists after Stalin's death in 1953 this obstacle needed to be cleared away. In my talk I discuss these issues and how the Institute for Theoretical Physics in Copenhagen came to be an important meeting place for physicists from the East and West from the mid-1950s.

Implementation of a new Foundations Concept for Offshore Wind Farms

DEFF Research Database (Denmark)

Ibsen, Lars Bo

2008-01-01

The foundation principles for the recent major offshore wind farm projects in Europe have been dominated by two types of foundation solutions, the gravitational foundation and the monopile. A fully operational 3.0 MW offshore wind turbine was installed on a prototype of the bucket foundation...... at the test field in Frederikshavn in December 2002. A five-year research and development project has proven the bucket foundation to be feasible in suitable soil conditions in water depth from near shore to approximately 40 meters. The bucket foundation design reduces the steel weight by half compared...... with a traditional monopile solution and the installation of the bucket foundation is much easier and does not require heavy installation equipment. In this paper the full-scale field installation of the prototype is described. A design procedure has been developed in cooperation with the certifying party in order...

Cost-efficient foundation structures for large offshore wind farms

International Nuclear Information System (INIS)

Birch, C.; Gormsen, C.; Lyngesen, S.; Rasmussen, J. L.; Juhl, H.

1997-01-01

This paper presents the results of the development of a cost-efficient foundation for large (1.5 MW) offshore wind farms at water depth of 5 to 11 m. Previously, medium sized wind turbines (500 kW) in Denmark have been installed offshore at water depths of approximately 5 m on concrete gravity foundations. The installation of larger turbines at greater depth does, however, hold great promise in terms of wind environment and environmental considerations. The costs of a traditional gravity foundation at these increased water depths is expected to be prohibitive, and the aim of the project has been to reduce the foundations costs in general. This paper describes the theoretical basis for the geotechnical and structural design of three alternative concepts and presents an optimised layout of each based on a research and development project. The basis has been a wind farm consisting of 100 turbines. The R and D project has been undertaken by the consulting engineers Nellemann, Nielsen and Rauschenberger A/S (Gravity foundation), LICengineering A/S (Mono pile) and Ramboell (Tripod) in co-operation with the Danish utility engineering companies Elkraft and Elsamprojekt A/S. The project was partly financed by the participants and by the Danish Energy Agency through their 1996 Energy Research Programme (EFP-96). (au) 18 refs

To investigate the association between radiation exposure from the atomic bombings and the prevalence of age-related macular degeneration (AMD) among older residents of Hiroshima and Nagasaki. The Adult Health Study is a cohort study of atomic bomb survivors living in Hiroshima and Nagasaki, comprising 2153 participants who underwent examinations with retinal fundus photographs in 2006-2008. The radiation dose to the eye for the analysis was estimated with the revised dosimetry system (DS02). The retinal photographs were graded according to the Wisconsin Age-Related Maculopathy Grading System modified for nonstereoscopic retinal images. Early and late AMD were defined according to the type of lesion detected in the worse eye of the participants. Person-specific data were analyzed by using a logistic regression model to assess the association between radiation dose and AMD. Among the 1824 subjects with gradable retinal images (84.7% of the overall participants), the estimated eye dose was widely distributed, with a mean of 0.45 Gy and standard deviation of 0.74 Gy. The prevalence of early and late AMD was 10.5% and 0.3%, respectively. There were no significant associations between radiation dose and AMD, with each 1-Gy increase in exposure, adjusted odds ratio was 0.93 (95% confidence interval [CI], 0.75-1.15) for early AMD and 0.79 (95% CI, 0.21-2.94) for late AMD. No significant associations were found between atomic bomb irradiation early in life and the prevalence of early or late AMD later in life among Japanese atomic bomb survivors.

Radiation standards and A-bomb survivors

International Nuclear Information System (INIS)

Alvarez, R.

1984-01-01

For more than 33 years, the US government has supported the Life Span Study of Japanese survivors as a follow-up of the 1945 nuclear bombings of Hiroshima and Nagasaki. Since 1975, the study has been funded jointly by the United States and Japan under the auspices of the Radiation Effects Research Foundation. In the May issue of this bulletin radiation epidemiologists Dr. Alice Stewart and George Kneale raise perhaps the most fundamental question of all: Does the Japanese A-bomb survivor study have any value in deriving risk estimates for low-level radiation. On the basis of data published by the Radiation Effects Research Foundation in 1978, Stewart and Kneale suggest that Foundation analysts have confused long-term effects of tissue-destructive high doses with single-cell low-dose effects. If they are correct, the method of linear extrapolation from high-dose studies for low-level radiation risk estimates is invalid. The author feels the A-bomb survivors study should be opened up to an independent peer review process

Mortality statistics among atomic bomb survivors in Hiroshima Prefecture. 1968-1972

Energy Technology Data Exchange (ETDEWEB)

Kurihara, M; Munaka, M; Hayakawa, N; Yamamoto, H; Ueoka, H; Ohtaki, M [Hiroshima Univ. (Japan). Research Inst. for Nuclear Medicine and Biology

1981-12-01

In a comparative analysis of mortality among atomic bomb survivors versus the non-exposed, both resident in Hiroshima Prefecture, it was found that in addition to leukaemia, malignant lymphoma, multiple myeloma, and cancers of the thyroid gland, breast, lung, esophagus, stomach, urinary organs and salivary gland which have been reported from the past to be elevated in risk among atomic bomb survivors, cancers of the colon, larynx, accessory sinuses, uterus, ovary and testis, diseases of the blood, cirrhosis of liver, hypertensive disease and diabetes mellitus were elevated in risk, but the risk of cerebrovascular disease, heart disease, peptic ulcer, gastroenteritis, senility, and accidents was lower than the non-exposed. The relationship of atomic bomb exposure to the relative risk of cancers of the lung, breast, uterus, and testis could be readily explained, but the relationship between atomic bomb exposure and the relative risk of cancers of many other sites, diseases of the blood, and other causes of death was inconsistent. One of the reasons why the risk of senility was low and the risk of diseases of the blood, malignant neoplasms, diabetes mellitus, and hypertensive disease was high is considered to be the higher diagnostic accuracy in atomic bomb survivors.

Full Text Available Explosion of the bombs in Hiroshima and Nagasaki corresponds to the only historical moment when atomic bombs were used against civilians. This event triggered countless investigations into the effects and dosimetry of ionizing radiation. However, none of the investigations has used the victims' bones as dosimeter. Here, we assess samples of bones obtained from fatal victims of the explosion by Electron Spin Resonance (ESR. In 1973, one of the authors of the present study (SM traveled to Japan and conducted a preliminary experiment on the victims' bone samples. The idea was to use the paramagnetism induced in bone after irradiation to measure the radiation dose. Technological advances involved in the construction of spectrometers, better knowledge of the paramagnetic center, and improvement in signal processing techniques have allowed us to resume the investigation. We obtained a reconstructed dose of 9.46 ± 3.4 Gy from the jawbone, which was compatible with the dose distribution in different locations as measured in non-biological materials such as wall bricks and roof tiles.

The Thoracic Surgery Foundation for Research and Education (TSFRE) was formed in 1991 with the primary goals of generating new knowledge and nurturing the development of surgeon-scientists. The purpose of this article is to determine how effective the TSFRE has been in achieving these goals. A survey instrument was sent electronically to all former and current TSFRE research award recipients. Major themes included the benefits on TSFRE award recipients with respect to career choices of thoracic surgery, progress toward research independence, and the ability to leverage TSFRE funds to more substantive National Institutes of Health (NIH) awards. Success rates for NIH funding were confirmed using NIH Research Portfolio Online Reporting Tools. The total completed survey response rate was 70% (75/107). The response rates for each group were as follows: resident 74% (28/38), faculty 85% (29/34), Braunwald 50% (9/18), and TSFRE/NIH K-award 65% (11/17). The funding rate for all grants was 14% (90/619). For resident research awardees, 81% (34/42) are cardiothoracic surgeons or are thoracic surgery residents. The conversion rate for existing TSFRE/NIH co-sponsored K-awards to R01 grants is 40% at 5 years compared with a 20% K to R conversion rate for all NIH K-award recipients. K to R conversion rates for junior faculty grant awardees without a prior K-award is 44%, which is much higher than NIH rates for all new investigator R01 awards. The return on investment for TSFRE funding for surgeon-scientists is resoundingly positive with respect to promoting careers in cardiothoracic surgery and to obtaining subsequent NIH funding for thoracic surgeon investigators.

The Skin Products Assessment Research Committee was created by the Plastic Surgery Educational Foundation in 2006. The Skin Products Assessment Research study aims were to (1) develop an infrastructure for Plastic Surgery Educational Foundation-conducted, industry-sponsored research in facial aesthetic surgery and (2) test the research process by comparing outcomes of the Obagi Nu-Derm System versus conventional therapy as treatment adjuncts for facial resurfacing procedures. The Skin Products Assessment Research study was designed as a multicenter, double-blind, randomized, controlled trial. The study was conducted in women with Fitzpatrick type I to IV skin, moderate to severe facial photodamage, and periocular and/or perioral fine wrinkles. Patients underwent chemical peel or laser facial resurfacing and were randomized to the Obagi Nu-Derm System or a standard care regimen. The study endpoints were time to reepithelialization, erythema, and pigmentation changes. Fifty-six women were enrolled and 82 percent were followed beyond reepithelialization. There were no significant differences in mean time to reepithelialization between Obagi Nu-Derm System and control groups. The Obagi Nu-Derm System group had a significantly higher median erythema score on the day of surgery (after 4 weeks of product use) that did not persist after surgery. Test-retest photographic evaluations demonstrated that both interrater and intrarater reliability were adequate for primary study outcomes. The authors demonstrated no significant difference in time to reepithelialization between patients who used the Obagi Nu-Derm System or a standard care regimen as an adjunct to facial resurfacing procedures. The Skin Products Assessment Research team has also provided a discussion of future challenges for Plastic Surgery Educational Foundation-sponsored clinical research for readers of this article.

Environmental Foundations in Germany

Directory of Open Access Journals (Sweden)

Thomas Krikser

2015-05-01

Full Text Available Foundations in Germany were examined in the context of environmental issues. Data from environmental foundations show that there is huge difference between private and public foundations concerning financial settings. Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.

Finding peace from Hiroshima. One oncologist's fight to rectify the damage caused by radiation

International Nuclear Information System (INIS)

Skoufalos, M.N.

2006-01-01

The article informs about one oncologist's fight to rectify the damage caused by radiation. In a small town just outside Osaka, Japan, Ritsuko Komaki was born, quite literally, into the atomic age. She was just an infant in 1945 when the first atomic bomb ever detonated on a human population devastated her family's ancestral home of Hiroshima. One of her friends, Sasaki was diagnosed with leukemia, and was later hospitalized with bone marrow suppression. Her grandmother had been exposed to the same chemical radiation that Sasaki had, yet never contracted leukemia despite presenting with all the other side effects of exposure. Komaki wa wondering why her grandmother never had any leukemia, but Sadako did? She never had any cancer, but she had all the symptoms of exposure, e.g. hair loss, diarrhea and bone marrow problems. During medical school, Komaki volunteered her summers at the Atomic Bomb Casualty Commission, the institute the United States built in Japan to examine the victims of atomic exposure. Anyone diagnosed as anemic underwent a bone marrow exam, and Komaki learned a great deal about chromosomal abnormalities by performing blood tests alongside visiting researchers from Yale University and other American hospitals. The bombings of Hiroshima and Nagasaki had fostered a national paranoia about radiation and radioactivity. In Japan, they hate radiation, and for so many years, they did not want to hear about radiation therapy. Patients had an illogical fear of it that delayed offering it as treatment there. In Japan, the majority of cancer treatment culminated in surgery. Radiation oncology was not a recognized specialization; oncologists were grouped in with diagnostic radiation techs. Yet today, Ritsuko Komaki, MD, is the chief operating officer of one of the most sophisticated radiation oncology treatment facilities in the United States: the 120 million US Dollar M.D. Anderson Cancer Center in Houston. And ironically, the technical equipment that forms

Serum pepsin levels Hiroshima adult health study. Relation to radiation, ABO blood groups, and gastrointestinal diseases

Energy Technology Data Exchange (ETDEWEB)

Knittle, J L

1961-07-12

At the ABCC clinic in Hiroshima 1330 subjects were investigated as to serum pepsin levels over a four month period. The normal mean values compared well with those reported for a United States population using a similar technique. There appeared to be no significant change in serum pepsin level with age, and no difference could be detected among individuals of the ABO blood groups. No relationship was found between serum pepsin level and exposure to ionizing radiation. Patients with gastric and duodenal ulcers had mean levels which were higher than normal mean values, while patients with leukemia had lower than normal mean levels. Patients with gastric polyps and gastric cancer had normal mean values. It is believed that the relation of serum pepsin activity to cancer of the stomach is not settled and deserves further investigation. 23 references, 2 figures, 4 tables.

Periodic materials-based vibration attenuation in layered foundations: experimental validation

International Nuclear Information System (INIS)

Xiang, H J; Shi, Z F; Wang, S J; Mo, Y L

2012-01-01

Guided by the recent advances in solid-state research in periodic materials, a new type of layered periodic foundation consisting of concrete and rubber layers is experimentally investigated in this paper. The distinct feature of this new foundation is its frequency band gaps. When the frequency contents of a wave fall within the range of the frequency band gaps, the wave, and hence its energy, will be weakened or cannot propagate through the foundation, so the foundation itself can serve as a vibration isolator. Using the theory of elastodynamics and the Bloch–Floquet theorem, the mechanism of band gaps in periodic composites is presented, and a finite element model is built to show the isolation characteristic of a finite dimensional periodic foundation. Based on these analytical results, moreover, a scaled model frame and a periodic foundation were fabricated and shake table tests of the frame on the periodic foundation were performed. Ambient, strong and harmonic vibration attenuations are found when the exciting frequencies fall into the band gaps. (fast track communication)

2013-01-01

The aim of this thesis is the description of the process of institutionalization of nuclear research in Austria in the context of the „Atoms for Peace“ program in the 1950s. This aspect of the history of Austrian nuclear research has been relatively unexplored. The focus of this work is the presentation of measures that have been put in Austria to participate in the 'Atoms for Peace' program. Moreover, the expectations and goals of the Austrian nuclear program are analyzed. For this purpose, foundation, structure and research activities of the “Austrian Atomic Energy Commission”, the “Austrian Society for the Study of Atomic Energy” and the “Nuclear Reactor Centre Seibersdorf“ in the period from 1954 until about 1970 are examined. To establish a relationship with the international historical research of the history of nuclear research, the Austrian situation is compared to the Swiss and the German. It turns out that the Austrian expectations and objectives in nuclear research at the beginning of the period of observation roughly corresponded with the international trends. It also follows that by the establishment of the SGAE and the “Nuclear Reactor Centre Seibersdorf“ the development course of Austrian nuclear research occupied a special position compared to foreign institutions.(author) [de

SUSTAINABLE CONCRETE FOR WIND TURBINE FOUNDATIONS.

Energy Technology Data Exchange (ETDEWEB)

BERNDT,M.L.

2004-06-01

The use of wind power to generate electricity continues to grow, especially given commitments by various countries throughout the world to ensure that a significant percentage of energy comes from renewable sources. In order to meet such objectives, increasingly larger turbines with higher capacity are being developed. The engineering aspects of larger turbine development tend to focus on design and materials for blades and towers. However, foundations are also a critical component of large wind turbines and represent a significant cost of wind energy projects. Ongoing wind research at BNL is examining two areas: (a) structural response analysis of wind turbine-tower-foundation systems and (b) materials engineering of foundations. This work is investigating the dynamic interactions in wind turbine systems, which in turn assists the wind industry in achieving improved reliability and more cost efficient foundation designs. The results reported herein cover initial studies of concrete mix designs for large wind turbine foundations and how these may be tailored to reduce cost and incorporate sustainability and life cycle concepts. The approach taken was to investigate material substitutions so that the environmental, energy and CO{sub 2}-impact of concrete could be reduced. The use of high volumes of ''waste'' materials in concrete was examined. These materials included fly ash, blast furnace slag and recycled concrete aggregate. In addition, the use of steel fiber reinforcement as a means to improve mechanical properties and potentially reduce the amount of bar reinforcement in concrete foundations was studied. Four basic mixes were considered. These were: (1) conventional mix with no material substitutions, (2) 50% replacement of cement with fly ash, (3) 50% replacement of cement with blast furnace slag and (4) 25% replacement of cement with fly ash and 25% replacement with blast furnace slag. Variations on these mixes included the addition of 1

Activating analytic thinking enhances the value given to individualizing moral foundations.

Science.gov (United States)

Yilmaz, Onurcan; Saribay, S Adil

2017-08-01

Two central debates within Moral Foundations Theory concern (1) which moral foundations are core and (2) how conflict between ideological camps stemming from valuing different moral foundations can be resolved. Previous studies have attempted to answer the first question by imposing cognitive load on participants to direct them toward intuitive and automatic thought. However, this method has limitations and has produced mixed findings. In the present research, in two experiments, instead of directing participants toward intuitive thought, we tested the effects of activating high-effort, analytic thought on participants' moral foundations. In both experiments, analytic thought activation caused participants to value individualizing foundations greater than the control condition. This effect was not qualified by participants' political orientation. No effect was observed on binding foundations. The results are consistent with the idea that upholding individualizing foundations requires mental effort and may provide the basis for reconciliation between different ideological camps.

The dissertation project seeks to analyse the photographic positions that deal with the atomic bomb attacks on Hiroshima and Nagasaki and the accident of the nuclear power plant in Chernobyl. This focus includes press photographs of the events as well as artistic, documentary and touristic images that take an approach towards the disasters often years after and hereby form iconographic or material references to the events. The study reveals central strategies for photographic images of atomic catastrophes, be they of military or civil nature. It is the inability to visualize non-visible nuclear rays or the complexity of processes on an atomic level that has turned out to be crucial. This incapacity of making images, a paradigm of invisibility, substantially coins the cultural role of the events. The question of how a society deals with these abstract potentials of nuclear technology has turned out to be always anew of high relevance in regard to ecological, social and technological policies of images.

Comparison of death certificate and autopsy diagnoses - Hiroshima. [Cause of death

Energy Technology Data Exchange (ETDEWEB)

Stone, R S; Anderson, Jr, P S

1960-09-14

In this report evaluation of the death certificates has been on the basis of comparison with recorded autopsy diagnoses without review of the latter. An attempt has been made to evaluate limitations inherent in this method. The cases analyzed here represent the ABCC Hiroshima autopsy series from 1949 through 1959. Post mortem examinations on stillbirths and neonatal deaths that were collected during the years 1948 through 1953 were excluded from consideration because such cases are not pertinent to the general problems under study. With this limitation 1304 cases were available for matching. In 139 of these cases the death certificates were not available through the mechanisms of the overall study, so 1165 cases remained. Before comparisons are made the most important questions that must be answered about the materials and methods of the present investigation are: (1) is the autopsy-death certificate series a representative sample of all deaths in the population; (2) are the autopsy diagnoses correct; (3) are the death certificates properly understood and coded; and (4) are biologically meaningful groupings chosen for comparison between autopsy cause of death and death certificate cause of death. Because it is not possible to provide exact answers to all of these questions the doubt that they raise must be admitted but evaluated in the perspective of that part of the answer which is known.

1980-01-01

The death from leukemia among Hiroshima citizens from 1971 to 1978 was investigated. The total number of dead citizens was 241, and 64 of them were a-bomb survivors. Thirty-seven of a-bomb survivors were exposed to a-bomb within 2 km from hypocenter. Seventy-seven of remaining 177 citizens were born after the explosion of a-bomb, but they were not children of a-bomb survivors exposed directly to a-bomb. The mortality of a-bomb survivors exposed near the hypocenter was 1.67 (within 2 km) - 2.51 (within 1.5 km) times that of those exposed far from the hypocenter. The mortality of a-bomb survivors exposed within 1.5 km was significantly high. The death risk from leukemia was significantly high in women. The estimated exposure dose was over 1 rad in 25 of abovementioned 37 a-bomb survivors, and it was over 10 rad in 21 and over 100 rad in 10 of 25. Seven of 10 a-bomb survivors exposed over 100 rad were women. The age at the exposure was under 10 years in 1, teens in 1, twenties in 2, and over thirty in 6. The type of leukemia was acute in 8 and chronic in 2. Both types were myelogenous leukemia. Five of these 10 a-bomb survivors died after 1976. (Tsunoda, M.)

Shells on elastic foundations

1977-01-01

No realistic analytical work in the area of Shells on Elastic Foundations has been reported in the literature. Various foundation models have been proposed by several authors. These models involve one or more than one parameters to characterise the foundation medium. Some of these models cannot be used to derive the basic equations governing the behaviour of shells on elastic foundations. In the present work, starting from an elastic continuum hypothesis, a mathematical model for foundation has been derived in curvilinear orthogonal coordinates by the help of principle of virtual displacements, treating one of the virtual displacements as known to satisfy certain given conditions at its edge surfaces. In this model, several foundation parameters can be considered and it can also be used for layered medium of both finite and infinite thickness. (Auth.)

One hundred and fifty-two women living in Hiroshima underwent physical measurements in 1970 and 1976. Those in the short-distance group (60) were directly exposed to the a-bomb within 1 km of the center of explosion. Those in the long-distance group (92) either were directly exposed over 3 km from the center of explosion, entered the city on or following the 4th day after the explosion, or nursed the exposed and disposed of the dead. Changes in physical measurement values were determined. Systolic pressure was more elevated and grasping power and vital capacity decreased more in the short-distance group than in the long-distance group. However, there was no statistically significant difference between both groups. There were few other differences between the groups. Regarding those under the age of 29 at the time of exposure, the physiological age, estimated from physical abilities (8 items were measured), was about 1 year older than the actual age at the time of the investigation. However, as the actual age increased, the physiological age tended to greatly decrease. (Tsunoda, M.)

A foundation for foundation phase teacher education: Making wise educational judgements

2014-12-01

Full Text Available We start our paper with a critical exploration of the current ‘back to basics’ approach in South African foundation phase teacher education with its emphasis on strengthening the teaching of subject knowledge. We claim that such a proposal first demands an answer to the question ‘what is foundational in foundation phase teaching?’ We propose an answer in three stages. First we argue that teacher education should be concerned not only with schooling or qualification (knowledge, skills and dispositions and socialisation, but, drawing on Gert Biesta’s work, also with subjectification (educating the person towards the ability to make wise educational judgements. Secondly, these three aims of education lead to five core principles, and we finish by showing how these principles inform our storied, thinking and multimodal/semiotic curriculum. Our answer to our leading question is that pedagogical ‘know-how’ and views of ‘child’ and ‘childhood’ constitute the subject knowledge that is foundational in the foundation phase curriculum.

Cigarette smoking and radiation exposure in relation to cancer mortality, Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Prentice, R.L.; Yoshimoto, Yasuhiko; Mason, M.W.

1983-05-01

Cancer mortality among 40,498 Hiroshima and Nagasaki residents was examined in relation to cigarette smoking habits and estimated atomic bomb radiation exposure. Relative risk models that are either multiplicative or additive in the two exposures (smoking radiation) were emphasized. Most analyses were directed toward all nonhematologic cancer, stomach cancer, lung cancer, or digestive cancer other than stomach, for which there were, respectively, 1,725, 658, 281, and 338 deaths in the follow-up period of this study. Persons heavily exposed to both cigarette smoke and radiation were found to have significantly lower cancer mortality than multiplcative relative risk models would suggest for all nonhematologic cancer, stomach cancer, and digestive cancer other than stomach. Surprisingly, the relative risk function appeared not only to be submultiplicative for these cancer sites, but to be subadditive as well. The lung cancer relative risk function could not be distinguished from either a multiplicative or an additive form. The number of deaths was sufficient to permit some more detailed study of all nonhematologic cancer mortality: Relative risk functions appeared to be consistent between males and females though a paucity of heavy smoking females limits the precision of this comparison.

Relationship of stature to gamma and neutron exposure among atomic bomb survivors aged less than 10 at the time of the bomb, Hiroshima and Nagasaki

International Nuclear Information System (INIS)

Ishimaru, Toranosuke; Amano, Takako; Kawamoto, Sadahisa.

1982-10-01

A reanalysis has been undertaken of the relationship of attained adult height of Hiroshima and Nagasaki atomic bomb survivors aged less than 10 at the time of the bomb (ATB) to radiation dose based upon new dosimetry data. The present analysis aims to examine the relationship of stature to radiation dose in terms of gamma rays and neutrons, separately. The 628 individuals were selected from Hiroshima and Nagasaki survivors, aged less than 10 ATB, whose doses were available, and whose statures were recorded at the Adult Health Study (AHS) biennial health examination during 1970-72. To ascertain the relationship of attained adult stature to gamma and neutron doses three doseresponse models were applied to the data. The analysis revealed that the attained height is a separate function of exposure to gamma rays and neutrons. The model assuming a squared term dependence on gamma rays and a linear dependence on neutrons provides a better explanation of the data. The regression coefficient associated with the squared gamma dose is -0.00000927 and the coefficient associated with neutron dose is -0.0172. The relative biological effectiveness of neutrons in relation to gamma radiation with respect to the effect for diminished development of stature is estimated as 43.1 / √Dn in kerma (Dn=neutron dose). The 95% confidence limits are 19.3 / √Dn--96.5 / √Dn. (author)

Malignant breast tumors among Atomic Bomb Survivors, Hirsoshima and Nagasaki, 1950 to 1974

International Nuclear Information System (INIS)

Tokunaga, M.; Norman, J.E. Jr.; Asano, M.; Tokuoka, S.; Ezaki, H.; Nishimori, I.; Tsuji, Y.

1979-01-01

From 1950 to 1974, 360 cases of malignant breast tumors were identified among the 63,000 females of the Radiation Effects Research Foundation's (Hiroshima and Nagasaki) Extended Life-Span Study sample of survivors of the 1945 atomic bombings of Hiroshima and Nagasaki; 288 of these females were residing in one of these two cities at the time of bombing (ATB). Two-thirds of all cases were classified as breast cancers on the basis of microscopic review of slides, and 108 cases received an estimated breast tissue dose of at least 10 rads. The number of cases of radiogenic breast cancer could be well estimated by a linear function of radiation dose for tissue doses below 200 rads. Excess risk estimates, based on this function, for women 10 to 19, 20 to 29, 30 to 39, and 50 years old or older ATB were 7.3, 4.2, 2.6, and 4.7 cases per million women per year per rad, respectively. Women irradiated in their forties showed no dose effect. Among all women who received at least 10 rads, those irradiated before age 20 years will have experienced the highest rates of breast cancer throughout their lifetimes. Separate excess risk estimates for Hiroshima and Nagasaki did not differ significantly, which indicates that for radiogenic breast cancer the effects of neutrons (emitted only in the Hiroshima explosion) and gamma radiation were about equal. Radiation did not reduce the latency period for the development of breast cancer, which was at least 10 years. The distribution of histologic types of cancers did not vary significantly with radiation dose. The data suggested that irradiation prior to menarche conferred a greater risk than irradiation after menarche

Static Behaviour of Bucket Foundations

DEFF Research Database (Denmark)

Larsen, Kim André

One new foundation concept in relation to offshore wind turbines is bucket foundations. The concept is known from the oil and gas industry, though the load conditions here are significantly different. The bucket foundation can be used as monopod or e.g. tripod foundations for offshore wind turbines....... The monopod concept is investigated in this thesis, regarding the static behaviour from loads relevant to offshore wind turbines. The main issue in this concept is the rotational stiffness of the foundation and the combined capacity dominated by moments. The vertical bearing capacity of bucket foundations...... theory is proposed. The proposed expression applies to plane strain as well as axis-symmetric stress conditions for foundations with smooth or rough bases. A thorough experimental investigation of the static behaviour of bucket foundations subjected to combined loading is carried out. Laboratory tests...

Experimental study on dynamic behavior of large scale foundation, 1

International Nuclear Information System (INIS)

Hanada, Kazufumi; Sawada, Yoshihiro; Esashi, Yasuyuki; Ueshima, Teruyuki; Nakamura, Hideharu

1983-01-01

The large-sized, high performance vibrating table in the Nuclear Power Engineering Test Center is installed on a large-scale concrete foundation of length 90.9 m, width 44.8 m and maximum thickness 21 m, weighing 150,000 tons. Through the experimental study on the behavior of the foundation, which is set on gravel ground, useful information should be obtained on the siting of a nuclear power plant on the Quaternary stratum ground. The objective of research is to grasp the vibration characteristics of the foundation during the vibration of the table to evaluate the interaction between the foundation and the ground, and to evaluate an analytical method for numerically simulating the vibration behavior. In the present study, the vibration behavior of the foundation was clarified by measurement, and in order to predict the vibration behavior, the semi-infinite theory of elasticity was applied. The accuracy of this analytical method was demonstrated by comparison with the measured results. (Mori, K.)

The evidential value of cosmetic foundation smears in forensic casework.

Science.gov (United States)

Gordon, Amanda; Coulson, Sally

2004-11-01

Cosmetic foundation products are easily transferred to clothing and other surfaces as a result of contact with such objects. Examination of past cases involving cosmetics in New Zealand has shown cosmetic foundation to be one of the more common cosmetic products encountered. The aim of this research was to determine the most discriminating method for the comparison of transferred foundation with samples obtained from a known source in forensic casework. Fifty-three foundation samples were analyzed by Fourier transform infrared spectroscopy (FTIR), gas chromatography with a flame ionization detector (GC-FID) and scanning electron microscopy-energy dispersive X-Ray analysis (SEM-EDX). It was found that a 5 mm2 section of a light smearing was enough to provide detectable results. The discriminating powers for FTIR, SEM-EDX and GC-FID were 98.3, 93.8, and 82.0% respectively. A combination of all three techniques provided a discriminating power of 99.7%, meaning that almost complete discrimination was achieved between the foundation samples.

Kitagawa, Ryuji; Kakitani, Satoru; Kuroda, Yoshimatsu; Matsuo, Sadao; Suzuoki, Tetsuro.

1980-01-01

The deuterium content of the constitutional and interlayer water extracted from the clay minerals (illite, montmorillonite, interstratified illite-montmorillonite mineral, kaolinite, halloysite) constituting the clay veins found in the granitic rocks in Hiroshima Prefecture was measured. The clay minerals were heated at 270 deg C to extract the interlayer water, then heated to 1,400 or 1,500 deg C to extract the constitutional water. The deuterium content of the local surface water collected from sampling points was measured. In the clay veins formed along perpendicular joints, the constituent clay minerals change from lower to upper part: illite → montmorillonite → kaolinite → halloysite. The deuterium content values of the constitutional water for illite and montmorillonite were estimated to be -67 to -69% and -86 to -89%, respectively. The deuterium content values of the constitutional water for halloysite range from -68 to -80% and for kaolinite from -63 to -67%. (J.P.N.)

ABCC-NIH adult health study, Hiroshima 1958-1960. Cardiovascular project report Number 6, heart size norm

Energy Technology Data Exchange (ETDEWEB)

Ueda, Shoichi, Russell, W.J.; Yano, Katsuhiko

1962-05-01

Utilizing the information obtained from the detailed clinical examinations of subjects seen at the Atomic Bomb Casualty Commission, standard heart size determinations in the Hiroshima population are provided. A formula has been devised to express the normal transverse cardiac diameter, obtained from the routine posteroanterior chest roentgenogram, in relation to weight, height, and age. The analysis was made for each sex separately. Values computed by using this formula are regarded as standard heart size. Deviations from the standard are interpreted as individual variability in the normal group, with a standard deviation of 9 mm. When this standard was applied to abnormal subjects, a high correlation between the relative heart size and the blood pressure or the presence of overt heart disease was evident. For this reason, the relative heart size for this standard should prove useful, together with other related factors, in the diagnosis and investigation of cardiovascular disease. A nomograph has been devised for practical use. 12 references, 7 figures, 4 tables.

Certain blood examinations were performed on a-bomb survivors having anemia more than moderate stage (the hemoglobin value under 9.0 g/dl), who were found out by the periodical health examination performed in Hiroshima-A-bomb Survivors Health Control Clinic during the latter period of the fiscal year 1975. The total number of a-bomb survivors who received the periodical health examination was 50,973, and the number of survivors whose hemoglobin value was under 9.0 g/dl was 201 (0.39%). The incidence of such anemia was high in women. There was not a relationship between this anemia and the exposure distance from the hypocenter. The incidence of this anemia was high in young a-bomb survivors, and more than 50% of a-bomb survivors having this anemia was under the age of 50. Iron-deficiency anemia was found in 88% of a-bomb survivors, and the course of their anemia ran in many years in many a-bomb survivors. (Tsunoda, M.)

Strengthening foundation phase teacher education through mentoring

Full Text Available This paper explores a multidimensional mentorship model implemented between lecturers from the foundation phase at the Wits School of Education and four master’s students from the University of Limpopo, as part of the Departments of Education’s research initiative to strengthen foundation phase teacher education. Using three critical incidents, we interrogate mentors’ experiences of their mentoring practices. Two sets of literature, mentoring and social capital are used as a lens for analysing these incidents. Initial findings suggest the relationship has moved from the initiation to cultivation stage (Kram, 1985; Ragins & Kram, 2007. But, cultural preconceptions, implicit assumptions and institutional practices can impede or enhance information flows and trust. It is argued that weak ties characterised by mentors’ heterogeneity is a strength that has resulted in growing professional development. Through a process of reflection-on-practice, we have begun to think of ourselves as a fledging community of practice. This opens up possibilities for the larger research project.

Numerical Modelling of Connections Between Stones in Foundations of Historical Buildings

Science.gov (United States)

Przewlocki, Jaroslaw; Zielinska, Monika; Grebowski, Karol

2017-12-01

The aim of this paper is to analyse the behaviour of old building foundations composed of stones (the main load-bearing elements) and mortar, based on numerical analysis. Some basic aspects of historical foundations are briefly discussed, with an emphasis on their development, techniques, and material. The behaviour of a foundation subjected to the loads transmitted from the upper parts of the structure is described using the finite element method (FEM). The main problems in analysing the foundations of historical buildings are determining the characteristics of the materials and the degree of degradation of the mortar, which is the weakest part of the foundation. Mortar is graded using the damaged-plastic model. In this model, exceeding the bearing capacity occurs due to the degradation of materials. The damaged-plastic model is the most accurate model describing the work and properties of mortar because it shows exactly what happens with this material throughout its total load history. For a uniformly loaded fragment of the foundation, both stresses and strains were analysed. The results of the analysis presented in this paper contribute to further research in the field of understanding both behaviour and modelling in historical buildings’ foundations.

Freshwater availability and coastal wetland foundation species: ecological transitions along a rainfall gradient

Science.gov (United States)

Osland, Michael J.; Enwright, Nicholas M.; Stagg, Camille L.

2014-01-01

Climate gradient-focused ecological research can provide a foundation for better understanding critical ecological transition points and nonlinear climate-ecological relationships, which is information that can be used to better understand, predict, and manage ecological responses to climate change. In this study, we examined the influence of freshwater availability upon the coverage of foundation plant species in coastal wetlands along a northwestern Gulf of Mexico rainfall gradient. Our research addresses the following three questions: (1) what are the region-scale relationships between measures of freshwater availability (e.g., rainfall, aridity, freshwater inflow, salinity) and the relative abundance of foundation plant species in tidal wetlands; (2) How vulnerable are foundation plant species in tidal wetlands to future changes in freshwater availability; and (3) What is the potential future relative abundance of tidal wetland foundation plant species under alternative climate change scenarios? We developed simple freshwater availability-based models to predict the relative abundance (i.e., coverage) of tidal wetland foundation plant species using climate data (1970-2000), estuarine freshwater inflow-focused data, and coastal wetland habitat data. Our results identify regional ecological thresholds and nonlinear relationships between measures of freshwater availability and the relative abundance of foundation plant species in tidal wetlands. In drier coastal zones, relatively small changes in rainfall could produce comparatively large landscape-scale changes in foundation plant species abundance which would affect some ecosystem good and services. Whereas a drier future would result in a decrease in the coverage of foundation plant species, a wetter future would result in an increase in foundation plant species coverage. In many ways, the freshwater-dependent coastal wetland ecological transitions we observed are analogous to those present in dryland

Quantum non-locality has been an extremely fruitful subject of research, leading the scientific revolution towards quantum information science, in particular, to device-independent quantum information processing. We argue that the time is ripe to work on another basic problem in the foundations of quantum physics, the quantum measurement problem, which should produce good physics in theoretical, mathematical, experimental and applied physics. We briefly review how quantum non-locality contributed to physics (including some outstanding open problems) and suggest ways in which questions around macroscopic quantumness could equally contribute to all aspects of physics.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

The development of technology for a directional soil compaction of tank foundations for oil and oil products storage is a relevant problem which solution will enable simultaneously provide required operational characteristics of a soil foundation and reduce time and material costs to prepare the foundation. The impact dynamics of rammers' operating elements on the soil foundation is planned to specify in the course of laboratory studies. A specialized technique is developed to justify the parameters and select the equipment for laboratory researches. The usage of this technique enabled us to calculate dimensions of the models, of a test bench and specifications of the recording equipment, and a lighting system. The necessary equipment for laboratory studies was selected. Preliminary laboratory tests were carried out. The estimate of accuracy for planned laboratory studies was given.

1983-01-01

This is a description, based largely on personal discussions, of the contributions of men from the Yale University School of Medicine to the saga of the immediate and long-term studies on the medical effects of the atomic bombs at Hiroshima and Nagasaki. They played key roles in the immediate studies of bomb effects, in the creation of long-term studies of delayed effects, and in elevating the Atomic Bomb Casualty Commission after 1955 to a position of excellence in its studies and relations with the Japanese. The accumulation of the information presented in this paper derives from research for the preparation of the history of the Atomic Bomb Casualty Commission. In 1975, the commission was passed to Japanese leadership as the Radiation Effects Research Foundation

What makes something a human right? What is the relationship between the moral foundations of human rights and human rights law? What are the difficulties of appealing to human rights? This book offers the first comprehensive survey of current thinking on the philosophical foundations of human rights. Divided into four parts, this book focusses firstly on the moral grounds of human rights, for example in our dignity, agency, interests or needs. 'Secondly, it looks at the implications that different moral perspectives on human rights bear for human rights law and politics. Thirdly, it discusses specific and topical human rights including freedom of expression and religion, security, health and more controversial rights such as a human right to subsistence. The final part discusses nuanced critical and reformative views on human rights from feminist, Kantian and relativist perspectives among others. The essays represent new and canonical research by leading scholars in the field. Each part is comprised of a set...

The incidence of lung cancer during 1950 - 80 in a cohort of Japanese atomic bomb survivors and controls was investigated. A total of 1,057 cases were identified; 608 of these diagnoses were based on some form of histopathologic examination, and 442 were confirmed by the present investigators. The distributions of histological types varied significantly between the sexes (p < .001), with adenocarcinoma more frequent among women and epidermoid and small cell carcinoma more frequent among men. The distributions of primary sites did not differ significantly between the sexes. The relative risk (RR) of lung cancer increased significantly with A-bomb radiation dose (p < .0001); based on tentative 1965 dose estimates as revised in 1978 (T65DR) and a linear RR model, the estimated RR at 100 rad (± SE) is 1.41 ± 0.09. Among Hiroshima survivors the women experienced radiation-related excess RR nearly twice as great as men (p = .06). RR increased with decreasing age at the time of bombing (p = .07), and after allowing for this effect, there was no significant evidence that RR varied systematically with attained age. Small cell carcinoma displayed somewhat greater sensitivity to radiation than did adenocarcinoma or epidermoid carcinoma; however the variation between the histology-specific RR functions was not statistically significant (p = .44).

The purpose of IPPNW is prevention of nuclear wars. As the first city suffered by Atomic Bomb, Doctors in Hiroshima Medical Community has a strongest wish to peace. IPPNW has been established in 1981 with the co-operative works of US and former Soviet Union. HICARE, Hiroshima International Council for Health Care of the Radiation-Exposed, was established in 1991. The purpose is, for the benefit of radiation-exposed populations in various parts of the world, to make the expertise available that has been accumulated in Hiroshima from the health care of A-bomb survivors and research on A-bomb radiation effects. By the concept of above HICARE accepted 9 researches from Kazakstan from 1992. And HICARE team visited Kazakstan twice. Firstly, in 1998 Professor Kamada visited here. He and other persons attended the second international meeting on the radiation, ecology and health, which was held in Semipalatinsk. They worked with the cooperation with other members from Hiroshima. Secondly, in 1999 five members visited with two Kazakstan researchers studying in Hiroshima. The aim of this mission was technical assistance from the thyroid examination of the people and the decision on the future direction

This study was designed to test a new approach for foundation insulation retrofits, with the goal of demonstrating improved moisture control, improved occupant comfort, and reduced heat loss. Because conducting experimental research on existing below-grade assemblies is very difficult, most of the results are based on simulations. The retrofit approach consists of filling open concrete block cores with an insulating material and adding R-10 exterior insulation that extends 1 ft below grade. The core fill is designed to improve the R-value of the foundation wall and increase the interior wall surface temperature, but more importantly to block convection currents that could otherwise increase moisture loads on the foundation wall and interior space. The exterior insulation significantly reduces heat loss through the most exposed part of the foundation and further increases the interior wall surface temperature. This improves occupant comfort and decreases the risk of condensation. Such an insulation package avoids the full-depth excavation necessary for exterior insulation retrofits, reduces costs, and eliminates the moisture and indoor air quality risks associated with interior insulation retrofits. Retrofit costs for the proposed approach were estimated at roughly half those of a full-depth exterior insulation retrofit.

Of the 19,701 deaths in the Life Span cohort between 1951--70, 22% came to autopsy. The autopsy procurement rate reached 45% in 1963 and declined thereafter. Problems and bias are discussed; autopsy rates were directly associated with radiation dose, especially in Hiroshima. Favorable autopsy procurement rates did not result from the rapport with survivors in the Adult Health Study. A study was made of stroke, ischemic heart disease, and cancer. The occurrence of cancer by site and cell type agrees with other data from Japan except for those cancers associated with prior ionizing radiation. Estimated radiation exposure data reveals no significant association for any disease other than some forms of cancer. (45 tables) (DLC)

Relation of radiation to gastric carcinoma observed in autopsy cases in a fixed population, Hiroshima and nagasaki 1961 - 74

A study was made of the relation to atomic bomb radiation of 535 cases of gastric carcinoma among 4,694 deaths occurring in a fixed population of Hiroshima and Nagasaki who were autopsied between 1961 and 1974. The proportion of all autopsies with gastric carcinoma as autopsy diagnosis tended to be high in the high dose group, but it could not be concluded with the present amount of information that there is a relation between gastric carcinoma and radiation in this autopsy study. Although no specific distribution of the histological types of gastric carcinoma was noted by radiation dose, the data indicated increases in the degree of extension of tumor cells in the gastric wall and the degree of metastasis to the lymph nodes seemed to be high in the high dose group.

Economic and Social Political Ideology and Homophobia: The Mediating Role of Binding and Individualizing Moral Foundations.

Barnett, Michael D; Öz, Haluk C M; Marsden, Arthur D

2018-05-01

Previous research has linked conservative political ideology with homophobia. Political ideology has also been linked to differences in moral decision-making, with research suggesting that conservatives and liberals may use different values in their moral decision-making processes. Moral foundations theory is a model of moral decision-making that proposes that individuals emphasize different domains in moral decision-making. Conservatives tend to emphasize binding foundations, while liberals tend to emphasize individualizing foundations. Utilizing large, ethnically diverse college samples, the purpose of these two cross-sectional studies (Study 1 N = 492; Study 2 N = 861) was to explore whether moral foundations mediate the relationship between political ideology and homophobia. These studies explored economic and social political ideology separately and utilized a two-factor model of moral foundations theory (individualizing and binding foundations). Results of both studies found that conservative economic and social political ideology was positively associated with homophobia. Study 1 found that both conservative economic and social political ideology had an indirect effect on homophobia through binding foundations. Study 2 found that both economic and social political ideology had an indirect effect on homophobia through both binding and individualizing foundations. Overall, the results were consistent with the notion that moral foundations may explain the relationship between political ideology and homophobia.

Theories of Social Media: Philosophical Foundations

Directory of Open Access Journals (Sweden)

Jiayin Qi

2018-02-01

Full Text Available Although many different views of social media coexist in the field of information systems (IS, such theories are usually not introduced in a consistent framework based on philosophical foundations. This paper introduces the dimensions of lifeworld and consideration of others. The concept of lifeworld includes Descartes’ rationality and Heidegger’s historicity, and consideration of others is based on instrumentalism and Heidegger’s “being-with.” These philosophical foundations elaborate a framework where different archetypal theories applied to social media may be compared: Goffman’s presentation of self, Bourdieu’s social capital, Sartre’s existential project, and Heidegger’s “shared-world.” While Goffman has become a frequent reference in social media, the three other references are innovative in IS research. The concepts of these four theories of social media are compared with empirical findings in IS literature. While some of these concepts match the empirical findings, some other concepts have not yet been investigated in the use of social media, suggesting future research directions. Keywords: Social media, Lifeworld, Consideration of others, Rationality, Historicity, Instrumentalism, Being-with, Presentation of self

Excavationless Exterior Foundation Insulation Field Study

Energy Technology Data Exchange (ETDEWEB)

Schirber, T.; Mosiman, G.; Ojczyk, C.

2014-10-01

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. However, such an approach can be very costly and disruptive when applied to an existing home, requiring deep excavation around the entire house. The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home. The approach consisted of using hydrovac excavation technology combined with a liquid insulating foam. The team was able to excavate a continuous 4" wide by 4' to 5' deep trench around the entire house, 128 linear feet, except for one small part under the stoop that was obstructed with concrete debris. The combination pressure washer and vacuum extraction technology also enabled the elimination of large trenches and soil stockpiles normally produced by backhoe excavation. The resulting trench was filled with liquid insulating foam, which also served as a water-control layer of the assembly. The insulation was brought above grade using a liquid foam/rigid foam hybrid system and terminated at the top of the rim joist. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

Adult T-cell leukemia (ATL), induced by human T-lymphotropic virus type-I (HTLV-I), is endemic in Nagasaki, Japan. To investigate the effects of atomic-bomb radiation on development of this specific type of leukemia, 6182 individuals in the Radiation Effects Research Foundation (RERF) Adult Health Study sample in Hiroshima and Nagasaki were examined for positive rate of HTLV-I antibody. Several lymphocyte parameters were also studied for 70 antibody-positive subjects in Nagasaki. The HTLV-I antibody-positive rate was higher in Nagasaki (6.36%) than in Hiroshima (0.79%) and significantly increased with increasing age, but no association was observed with radiation dose. Whether relationship existed between antibody titer levels and radiation dose among antibody-positive subjects was not clear. The frequency of abnormal lymphocytes tended to be higher in antibody-positive subjects than in antibody-negative subjects, and higher in females than in males regardless of radiation dose. The lymphocyte count was lower in antibody-positive subjects than in antibody-negative subjects and lower in female than in male subjects. No evidence was found to suggest that atomic-bomb radiation plays an important role in HTLV-I infection. (author).

The foundational principles as psychological lodestars: Theoretical inspiration and empirical direction in rehabilitation psychology.

Dunn, Dana S; Ehde, Dawn M; Wegener, Stephen T

2016-02-01

Historically, the Foundational Principles articulated by Wright (1983) and others guided theory development, research and scholarship, and practice in rehabilitation psychology. In recent decades, these principles have become more implicit and less explicit or expressive in the writings and work of rehabilitation professionals. We believe that the Foundational Principles are essential lodestars for working with people with disabilities that can guide inquiry, practice, and service. To introduce this special issues, this commentary identifies and defines key Foundational Principles, including, for example, Lewin's (1935) person-environment relation, adjustment to disability, the malleability of self-perceptions of bodily states, and the importance of promoting dignity for people with disabilities. We then consider the role the Foundational Principles play in the articles appearing in this special issue. We close by considering some new principles and their potential utility in rehabilitation settings. Readers in rehabilitation psychology and aligned areas (e.g., social-personality psychology, health psychology, rehabilitation therapist, psychiatry, and nursing) are encouraged to consider how the Foundational Principles underlie and can shape their research and practice.

This article discussed the design and primary issues related to installing the foundations for 3 wind turbines established for generating electricity at research stations in Antarctica. The extreme frigidity of the climate, the unusual geotechnical subsoil conditions, and the technology constraints resulting from isolation had to be contended with in all aspects of the project, including site evaluation, design, construction, and monitoring. The foundation design required strict tolerance on differential settlement. The estimation of creep settlement over the entire life of the project was the most important aspect. The surface loads on the foundation were grouped by load duration to estimate the corresponding creep settlement. The tower foundations were proposed as multi-leg arrangement buried at a relatively shallow depth within the continuous permafrost. The creep behaviour of the soils, estimates of long-term settlement, and the development of contingency and mitigation measures for non-compliant foundation behaviour were necessary to meet the allowable differential settlement of the towers. The paper described the subsurface conditions, the foundation system, and the performance data taken after one thaw season. Continued monitoring will ensure that performance requirements are met. 6 refs., 3 tabs., 10 figs.

Carcinoma of the uterine cervix

Hayakawa, Norihiko

1992-01-01

There are few reports on uterine cancer in relation to radiation. This chapter discusses uterine cancer in A-bomb survivors, with special reference to the mortality rate, in a review of the literature. The Atomic Bomb Casualty Commission has first discovered 28 cases of uterine cancer among A-bomb survivors during the period 1953-1957. Since 1970, mortality rate from uterine cancer has been investigated statistically according to the T65D system. The Radiation Effect Research Foundation (RERF) has revealed 282 death cases from uterine cancer during the period 1950-1974. The RERF's data up to 1982 has revealed no radiation-dependent mortality from uterine cancer. More recent data (1950-1985) has revealed that mortality rate was increased by 22% in A-bomb survivors exposed to 1 Gy or more. When mortality of uterine cancer was investigated statistically using the 1968-1982 data for the population of the Research Institute for Nuclear Medicine and Biology, Hiroshima University, it was 1.2 times higher in the entire exposed group and 1.4 times higher in the group of proximally exposed A-bomb survivors (within 2 km from the hypocenter) than the non-exposed group, with statistically significant difference. It tended to be high in the group of distally exposed A-bomb survivors (who entered the city within 3 days after A-bombing) than the non-exposed group. When comparing the group of Hiroshima City with the group of Hiroshima Prefecture, mortality from uterine cancer was 1.3 times higher in the municipal group for proximally exposed A-bomb survivors and 1.3 times higher in the prefectural group for distally exposed A-bomb survivors and the others. Mortality rate was highest within one year after the acquisition of health handbook in the exposed group. (N.K.)

Universics: a Theory of Universes of Discourse for Metamathematics and Foundations

Directory of Open Access Journals (Sweden)

Ioachim Drugus

2016-04-01

Full Text Available A new type of structures called ``universes'' is introduced to subsume the ``von Neumann universe'', ``Grothendieck universes'' and ``universes of discourse'' of various theories. Theories are also treated as universes, ``universes of ideas'', where ``idea" is a common term for assertions and terms. A dualism between induction and deduction and their treatment on a common basis is provided. The described approach referenced as ``universics'' is expected to be useful for metamathematical analysis and to serve as a foundation for mathematics. As a motivation for this research served the Harvey Friedman's desideratum to develop a foundational theory based on ``induction construction'', possibly comprising set theory. This desideratum emerged due to ``foundational incompleteness'' of set theory. The main results of this paper are an explication of the notion ``foundational completeness'', and a generalization of well-founded-ness.

2009-05-09

The Bill & Melinda Gates Foundation is a major contributor to global health; its influence on international health policy and the design of global health programmes and initiatives is profound. Although the foundation's contribution to global health generally receives acclaim, fairly little is known about its grant-making programme. We undertook an analysis of 1094 global health grants awarded between January, 1998, and December, 2007. We found that the total value of these grants was US$8.95 billion, of which $5.82 billion (65%) was shared by only 20 organisations. Nevertheless, a wide range of global health organisations, such as WHO, the GAVI Alliance, the World Bank, the Global Fund to Fight AIDS, Tuberculosis and Malaria, prominent universities, and non-governmental organisations received grants. $3.62 billion (40% of all funding) was given to supranational organisations. Of the remaining amount, 82% went to recipients based in the USA. Just over a third ($3.27 billion) of funding was allocated to research and development (mainly for vaccines and microbicides), or to basic science research. The findings of this report raise several questions about the foundation's global health grant-making programme, which needs further research and assessment.

The Logical Foundations of Mathematics offers a study of the foundations of mathematics, stressing comparisons between and critical analyses of the major non-constructive foundational systems. The position of constructivism within the spectrum of foundational philosophies is discussed, along with the exact relationship between topos theory and set theory.Comprised of eight chapters, this book begins with an introduction to first-order logic. In particular, two complete systems of axioms and rules for the first-order predicate calculus are given, one for efficiency in proving metatheorems, and

Cerebral vascular disease in Hiroshima. Report of a six-year period of surveillance, 1958 to 1964

Energy Technology Data Exchange (ETDEWEB)

Johnson, K G; Yano, Katsuhiko; Kato, Hiroo

1966-08-25

Cerebral vascular disease (CVD) in the population of Hiroshima, Japan, is described for the period 1958 to 1964. The incidence of CVD in the male population over 30 years of age was 7.4 per 1000 per year and in females 4.1, approximately twice the observed incidence of coronary heart disease. Being based on examined individuals only, these estimates are biased downward, perhaps by a factor of 10%. The frequency of cerebral thrombosis was twice that of cerebral hemorrhage. These findings on incidence and type of CVD are in accord with the known high incidence of this disease in Japan but do not suggest that any disease other than atherosclerosis of the cerebral arteries is responsible. Hypertension, cardiomegaly (ascertained by ECG or chest film), and proteinuria were important factors in the risk of subsequent CVD. The singular association between hypertension and CVD, and the evidence that CVD is declining in Japan, the US and Europe during a period of widespread use of antihypertensive agents, encourage further epidemiologic study in CVD. 30 references, 15 figures, 8 tables.

Diversity in science, technology, engineering, and mathematics (STEM) education and careers occupies center stage in national discussions on U.S. competitiveness in the 21st century. Women constitute roughly half the total workforce in the U.S., but they hold just 25% of mathematical and science jobs and 11% of engineering jobs. Women earn nearly 60% of all bachelors and masters degrees, except in physics, computer science, and engineering, where the percentages are 20-25%. This disparity is even more pronounced at the doctoral level, where women earn fewer than 20% of awarded Ph.D.'s in physics or engineering. However, at the high school level, there is far less gender disparity: both female and male students take comparable advanced physical science and math courses. What, then, accounts for the lack of gender diversity in STEM advanced education and career paths? In fact, there is no consensus even among experts. So, what information and strategies do the EPO community need to know and include as part of designing and implementing programs to encourage more girls and women to engage in STEM for the long term? The panelists will discuss foundational and current research on pressing questions on why these trends exist and what can be done to change them. They will highlight research and evaluation results from programs that are successfully engaging girls in STEM.

In order to rationalize the aseismatic design of nuclear power stations, it is necessary to elucidate the characteristics of effective input when the earthquake motion for the design is inputted in the foundations of nuclear power stations. In this study, among the research subjects concerning the reduction of effective earthquake input, regarding the uplift of foundations, its response characteristics and the method of the rational evaluation of earth contact ratio were experimentally examined, and the method of analysis which can evaluate the damping effect due to the uplift was proposed. The experimental method is reported. It was found that accompanying the uplift of foundations, vertical motion was induced, and horizontal motion showed nonlinear response. It was confirmed that the nonlinear response accompanying the uplift can be approximately evaluated by the conventional analysis technique using the S-R model. The current equation for evaluating earth contact ratio is adequate for a soft ground model, and tends to undervaluate for a hard ground model. The S-R analysis model introducing the experimentally obtained characteristics in the dampling coefficient of a nonlinear rocking spring was newly made. (Kako, I.)

Editorial research and the publication process in biomedicine and health: Report from the Esteve Foundation Discussion Group, December 2012

Marušić, Ana; Malički, Mario; von Elm, Erik

2014-01-01

Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

2011-12-01

Full Text Available The higher education system which entered a new period with the 1980s has in the last five years entered a phase of numerical enlargement and structural transformation. Having only 19 public universities in the early 1980s, the higher education system today have turned into a broad system with 85 public and 30 foundation universities. The research aims to discuss the role of foundation universities in the higher education policies implemented between the years 1980-2007. Among the five development plans prepared between 1980 and 2008, it was suggested for the first time with the sixth five-year development plan that foundations should be supported to establish private universities and policies was formulated accordingly. Mesut Yılmaz was the prime minister and Süleyman Demirel was the president who opened the highest number of foundation universities between 1980 and 2008. While the number of students between 1986-1987 was 426 in foundation universities, this number in foundation universities reached 109.903 in the 2006-2007 aca-demic year. The annual growth rate of the number of students in foundation universities within the twenty-year period is 32%. In the 2006-2007 academic year, the number of academic staff in foundation universities is 7766, of academic fellows is 2502, and of students is 109,903. The number of students per academic staff in foundation universities in the 2006-2007 academic year is 21, whereas the number of students per academic fellow is 44.

Towards an arithmetical logic the arithmetical foundations of logic

CERN Document Server

Gauthier, Yvon

2015-01-01

This book offers an original contribution to the foundations of logic and mathematics, and focuses on the internal logic of mathematical theories, from arithmetic or number theory to algebraic geometry. Arithmetical logic is the term used to refer to the internal logic of classical arithmetic, here called Fermat-Kronecker arithmetic, and combines Fermat’s method of infinite descent with Kronecker’s general arithmetic of homogeneous polynomials. The book also includes a treatment of theories in physics and mathematical physics to underscore the role of arithmetic from a constructivist viewpoint. The scope of the work intertwines historical, mathematical, logical and philosophical dimensions in a unified critical perspective; as such, it will appeal to a broad readership from mathematicians to logicians, to philosophers interested in foundational questions. Researchers and graduate students in the fields of philosophy and mathematics will benefit from the author’s critical approach to the foundations of l...

Case Study Research: Foundations and Methodological Orientations

Directory of Open Access Journals (Sweden)

Helena Harrison

2017-01-01

Full Text Available Over the last forty years, case study research has undergone substantial methodological development. This evolution has resulted in a pragmatic, flexible research approach, capable of providing comprehensive in-depth understanding of a diverse range of issues across a number of disciplines. Change and progress have stemmed from parallel influences of historical transformations in approaches to research and individual researcher's preferences, perspectives, and interpretations of this design. Researchers who have contributed to the development of case study research come from diverse disciplines with different philosophical perspectives, resulting in a variety of definitions and approaches. For the researcher new to using case study, such variety can create a confusing platform for its application. In this article, we explore the evolution of case study research, discuss methodological variations, and summarize key elements with the aim of providing guidance on the available options for researchers wanting to use case study in their work.

The road to Maxwell's demon conceptual foundations of statistical mechanics

CERN Document Server

Hemmo, Meir

2012-01-01

Time asymmetric phenomena are successfully predicted by statistical mechanics. Yet the foundations of this theory are surprisingly shaky. Its explanation for the ease of mixing milk with coffee is incomplete, and even implies that un-mixing them should be just as easy. In this book the authors develop a new conceptual foundation for statistical mechanics that addresses this difficulty. Explaining the notions of macrostates, probability, measurement, memory, and the arrow of time in statistical mechanics, they reach the startling conclusion that Maxwell's Demon, the famous perpetuum mobile, is consistent with the fundamental physical laws. Mathematical treatments are avoided where possible, and instead the authors use novel diagrams to illustrate the text. This is a fascinating book for graduate students and researchers interested in the foundations and philosophy of physics.

The Psychology of the Politics of Rape: Political Ideology, Moral Foundations, and Attitudes Toward Rape.

Science.gov (United States)

Barnett, Michael D; Hilz, Emily N

2018-04-01

Previous research has found that conservatives and liberals emphasize different moral foundations. The purpose of these two studies was to investigate whether moral foundations mediate the relationship between political ideology and attitudes toward rape among U.S. college students. In Study 1, moral foundations fully mediated the relationship between political ideology and rape myth acceptance. Study 2 generally replicated the results of Study 1, with binding foundations demonstrating the most consistent mediating effects. These results suggest that individual differences in moral decision-making may explain the relationship between political ideology and attitudes toward rape.

Experimental evaluation of a quasi-modal parameter based rotor foundation identification technique

Yu, Minli; Liu, Jike; Feng, Ningsheng; Hahn, Eric J.

2017-12-01

Correct modelling of the foundation of rotating machinery is an invaluable asset in model-based rotor dynamic study. One attractive approach for such purpose is to identify the relevant modal parameters of an equivalent foundation using the motion measurements of rotor and foundation at the bearing supports. Previous research showed that, a complex quasi-modal parameter based system identification technique could be feasible for this purpose; however, the technique was only validated by identifying simple structures under harmonic excitation. In this paper, such identification technique is further extended and evaluated by identifying the foundation of a numerical rotor-bearing-foundation system and an experimental rotor rig respectively. In the identification of rotor foundation with multiple bearing supports, all application points of excitation forces transmitted through bearings need to be included; however the assumed vibration modes far outside the rotor operating speed cannot or not necessary to be identified. The extended identification technique allows one to identify correctly an equivalent foundation with fewer modes than the assumed number of degrees of freedom, essentially by generalising the technique to be able to handle rectangular complex modal matrices. The extended technique is robust in numerical and experimental validation and is therefore likely to be applicable in the field.

Emotional foundations of cognitive control

Science.gov (United States)

Inzlicht, Michael; Bartholow, Bruce D.; Hirsh, Jacob B.

2015-01-01

Often seen as the paragon of higher cognition, here we suggest that cognitive control is dependent on emotion. Rather than asking whether control is influenced by emotion, we ask whether control itself can be understood as an emotional process. Reviewing converging evidence from cybernetics, animal research, cognitive neuroscience, and social and personality psychology, we suggest that cognitive control is initiated when goal conflicts evoke phasic changes to emotional primitives that both focus attention on the presence of goal conflicts and energize conflict resolution to support goal-directed behavior. Critically, we propose that emotion is not an inert byproduct of conflict but is instrumental in recruiting control. Appreciating the emotional foundations of control leads to testable predictions that can spur future research. PMID:25659515

2016-01-01

in Denmark. Industrial foundations are independent legal entities without owners or members typically with the dual objective of preserving the company and using excess profits for charity. We use a unique Danish data set to examine the governance of foundation-owned companies. We show that they are long......-term in several respects. Foundations hold on to their shares for longer. Foundation-owned companies replace managers less frequently. They have more conservative capital structures with less leverage. Their companies survive longer. Their business decisions appear to be more long term. This paper supports...... the hypothesis that time horizons are influenced by ownership structures and particularly that industrial foundations promote longtermism. Policymakers which are interested in promoting longtermism should allow and perhaps even encourage the creation of industrial foundations. More generally they should consider...

Moral foundations and political attitudes: The moderating role of political sophistication.

Science.gov (United States)

Milesi, Patrizia

2016-08-01

Political attitudes can be associated with moral concerns. This research investigated whether people's level of political sophistication moderates this association. Based on the Moral Foundations Theory, this article examined whether political sophistication moderates the extent to which reliance on moral foundations, as categories of moral concerns, predicts judgements about policy positions. With this aim, two studies examined four policy positions shown by previous research to be best predicted by the endorsement of Sanctity, that is, the category of moral concerns focused on the preservation of physical and spiritual purity. The results showed that reliance on Sanctity predicted political sophisticates' judgements, as opposed to those of unsophisticates, on policy positions dealing with equal rights for same-sex and unmarried couples and with euthanasia. Political sophistication also interacted with Fairness endorsement, which includes moral concerns for equal treatment of everybody and reciprocity, in predicting judgements about equal rights for unmarried couples, and interacted with reliance on Authority, which includes moral concerns for obedience and respect for traditional authorities, in predicting opposition to stem cell research. Those findings suggest that, at least for these particular issues, endorsement of moral foundations can be associated with political attitudes more strongly among sophisticates than unsophisticates. © 2015 International Union of Psychological Science.
