    We analyzed the risk in 2,743 atomic bomb survivors by using a new dosimetry system. From the database, we selected 2,743 exposed persons and a total of three times 2,743 age-matched controls who were living far from the center of the A-bomb radiation in Nagasaki at the time of the explosion and who were still alive in 1971. The mortalities from all causes for male subjects exposed were slightly lower than, or almost equal to, those of unexposed persons. Death from cancer, however, increased in both sexes after all levels of irradiation except in males exposed to 0.01-0.49 Gy. In males, the risk was showed significant reduction in death from all diseases other than cancer classified according to 0.31-0.40 Gy. (author)

    This is a retrospective review of gastric cancer in A-bomb survivors. Firstly, surgical cases of gastric cancer (1968-88) were compared in 514 A-bomb survivors and 1,092 non-exposed persons. The average age was 63.5 years in the exposed group and 60.0 years in the non-exposed group. Although there were much more men than women in the non-exposed group (67.3% vs 32.7%), there was no great difference in the exposed group (56.0% vs 44.0%). The frequency of early gastric cancer tended to be higher in the exposed group, and thus, both the curative resection and 5-year survival rates were slightly higher. This seems to have been attributed to periodical health examination for A-bomb survivors. Secondly, the frequency of gastric cancer was examined in relation to the age at the time of A-bombing (ATA). According to the ATA, 538 A-bomb survivors (1968-89) were divided into the <19 year group (n=118), 20-29 year group (n=134), 30-39 year group (n=178), and >40 year group (n=108). The <19 year group accounted for more A-bomb survivors directly exposed to A-bombing. Using 1,138 other non-exposed patients as controls, there was no factors specific to the exposed group. Thirdly, the distance from the hypocenter was examined in 569 A-bomb survivors (1966-1990) by dividing them into the {<=}2.0 km group (n=137), >2.1 km group (n=168), and secondarily exposed group (n=264). In all three groups, well-differentiated cancer was predominant. The frequency of poorly differentiated cancer was higher in those exposed nearer the hypocenter; this was significant in both the {<=}2.0 km and >2.1 km groups than the secondarily exposed group. In directly exposed groups, the frequency of poorly differentiated cancer was high in the age group of <50 and the frequency of well differentiated cancer was high in the age group of >60. This suggests the relationship between exposure doses and poorly differentiated gastric cancer. (N.K.).

    Our department of Neuropsychiatry has clarified the clinical features of several mental disorders and surveyed the causes of those disorders from the psychosocial aspect using the methodology of epidemiological psychiatric approach. Using this previous research experience, we began a long-planned study to examine the mental health state of atomic bomb survivors. Fifty-one years have passed since the atomic bombing, and the survivors must have suffered various psychosocial stresses, other than any direct effect on the central nervous system from exposure to radiation, and it is assumed that victims` mental state has been affected in various ways as a result. The subjects of the survey were 7,670 people who had regular health examinations for atomic bomb survivors during the study period of three years and who consented to participate in the study. Of the total, 226 subjects were selected for a second phase according to the results of the General Health Questionnaire 12-item Version which was used in the first phase of the survey. The results were as follows: 1. The distance from the hypocenter was related to the degree of ill health, and the percentage of people with a high score was greater among those exposed to the atomic bomb in proximity to the hypocenter. 2. 14.6% of the subjects were diagnosed as having some kind of mental disorders according to clinical interviews by trained psychiatrists. These results had not expected prior to the study. On the based of the study, we will try to establish a mental health support system for atomic bomb survivors. (author)

    The prevalence of roentgenologically-detected foreign bodies among atomic bomb (A-bomb) survivors was studied as an indicator of the A-bomb blast effects. Acupuncture was studied as an indicator of A-bomb-related abnormalities for which it was administered. All Adult Health Study subjects' roentgenograms demonstrating foreign bodies were reviewed. The frequency of glass and metal, and acupuncture needles were analyzed by distance from hypocenters, sex, age, body sites involved; and the subjects' shielding at the times of the A-bombs. The presence of glass fragments correlated closely with distance from hypocenter, heavy shielding from the A-bombs, and with adulthood, and they were more frequent in the chest than hand and wrist. Metal foreign bodies were more frequent in the hand and wrist than in the chest, and not associated with distance from hypocenter or heavy shielding. The prevalence of acupuncture needles increased with age, but did not correlate with A-bomb dose.

    The prevalence of roentgenologically-detected foregin bodies among atomic bomb survivors was studied as an indicator of the A-bomb blast effects. Acupuncture was studied as an indicator of possible A-bomb-related abnormalities for which it was administered. All available roentgenograms of Adult Health Study (AHS) subjects which demonstrated foreign bodies were reviewed. The frequency of glass and metal foreign bodies and of acupuncture needles was analyzed in detail. Analyses were made by distance from the hypocenter, sex, age, body sites involved, and shielding at the time of the A-bomb (ATB). The presence of glass fragments correlated closely with distance from the hypocenter, with heavy shielding from the A-bombs, and with adulthood, and they were more frequent in the chest than in the hand and wrist. On the contrary, metal foreign bodies were more frequent in the hand and wrist than in the chest, and were not associated with distance from hypocenter or heavy shielding. The prevalence of acupuncture needles increased with age, but did not correlate with A-bomb dose.

    Previous surveys of radiation therapy among the Life Span Study (LSS) population at the Radiation Effects Research Foundation (RERF) revealed that 1,670 (1.4%) of the LSS participants received radiation treatments before 1984. The data on therapeutic radiation doses are indispensable for studying the relationship between radiation treatments and subsequent cancer occurrences. In this study, the radiation treatments were reproduced experimentally to determine the scattered radiation doses. The experiments were conducted using a female human phantom and various radiation sources, including a medium-voltage X-ray machine and a (60)Co gamma-ray source. Doses were measured using thermoluminescence dosimetry and ionization chambers. Radiation doses were determined for the salivary glands, thyroid gland, breast, lung, stomach, colon, ovary and active bone marrow. The results have been used for documenting the organ doses received by patients in previous surveys. The contribution of therapeutic irradiation to the occurrence of chromosome aberrations was studied using data on doses to active bone marrow from both radiation treatments and atomic bomb exposures in 26 RERF Adult Health Study participants. The results suggest that radiation treatments contributed to a large part of their frequencies of stable-type chromosome aberrations. The therapeutic radiation doses determined in the present study are available for investigating the effects of therapeutic irradiation on the subsequent primary cancers among atomic bomb survivors who received radiation treatments.

    The Japanese atomic bomb survivors that were directly exposed to both γ rays and neutrons have been followed by the Radiation Effects Research Foundation (RERF). The estimation of the γ-ray risks requires some adjustment for the greater biological effect of the neutrons per unit dose. Because the small neutron doses and the predominant γ-ray doses are highly correlated, the neutron relative biological effectiveness (RBE) cannot be reliably estimated from the survivors' data and information from radiobiology must be invoked. As data became available on neutron doses, RERF has used a constant neutron RBE value of 10, even though radiobiological studies indicate that the RBE values appear to have considerably larger values at low doses. The approximation RBE = 10 assumes that if the RBE is variable it takes roughly this value in the range of total dose most relevant for linear risk estimation, namely about 1 Gy. We consider some possible RBE functions to explain the correct use and the impact of a dose-dependent RBE. However, we do not advocate any particular choice or even that a variable RBE be employed. Rather we show that the assumed neutron RBE, within a wide range of choices, is far less important to the outcome of risk assessment of the RERF data than generally believed. Some of these misperceptions have been related to the consideration of variable RBE functions, and without due attention to the fact that in the case of the A-bomb survivors' data, the mixed field of neutrons and γ rays must be considered. Therefore, the RBE value of neutrons is much lower than the RBE in pure neutron fields that are used in radiobiological experiments. Thus, applying the pure neutron field RBE to the mixed-field A-bomb radiation can lead to an overestimation of the actual neutron RBE for moderate total dose levels of 1 Gy by a factor of more than four. While in a pure neutron exposure the RBE depends on the neutron dose, in the mixed field it depends on both components of

    A female a-bomb survivor had anemia 18 years after the exposure to a-bomb. She was strongly suspected of developing leukemia, because she showed morphological abnormalities (erythrocytoblasts, megakaryocytes, myeloblasts, eosinocytes, and neutrocytes having 2 or 3 or 5 nuclei) and partial functional disorder extending 3 bone marrow systems and chromosome aberration. She died of hepatitis and atrioventricular block 11 years after the onset.

    A population based study was conducted to evaluate the risk of ovarian cancer among female atomic bomb (A-bomb) survivors in Nagasaki City by using data from 1973 to 1987 of the Nagasaki Tumor Resistry. The incidence rate of ovarian cancer in the total female population in Nagasaki City decreased at ages 50-59, 60-69, and 70-79 with advancing the periods investigated (1973-1977, 1978-1982, and 1983-1987). A similar trend in the incidence rate was also observed in A-bomb survivors. The summarized risk ratio (SRR) of ovarian cancer was not significantly higher in A-bomb survivors; SRR: 1.30 (95% confidence interval of SRR: 0.64-2.68) in the survivors exposed to the A-bomb radiation within 2 km of the hypocenter, and 1.07 (0.78-1.46) in the total population of A-bomb survivors. There was also no difference in histologic type of ovarian cancer between A-bomb survivors and non-exposed persons. It should be noted, however, that the incidence rate at age 40-49 was higher in A-bomb survivors than in non-exposed persons during the all periods investigated. A follow-up study is, therefore, still necessary to evaluate the risk of ovarian cancer in A-bomb survivors in Nagasaki city. (author).

    Atomic bomb survivors have been reported to have an increased risk of some cancers, especially leukemia. However, the risk of prostate cancer in atomic bomb survivors is not known to have been examined previously. This study examined the association between atomic bomb radiation and the incidence of prostate cancer among male Nagasaki atomic bomb survivors. The subjects were classified by distance from the hypocenter into a proximal group (<2 km), a distal group (≥2 km), and an early entrance group (those who entered the region <2 km from the hypocenter within 2 weeks after the explosion). Between 1996 and 2009, 631 new cases of prostate cancer were identified among approximately 18 400 male Nagasaki atomic bomb survivors who were alive in 1996. The Cox proportional hazard model was used to estimate the risk of prostate cancer development, with adjustment for age at atomic bomb explosion, attained age, smoking status, and alcohol consumption. Compared with the distal group, the proximal group had significant increased risks of total, localized, and high-grade prostate cancer (relative risk and 95% confidence interval: 1.51 [1.21-1.89]; 1.80 [1.26-2.57]; and 1.88 [1.20-2.94], respectively). This report is the first known to reveal a significant relationship between atomic bomb radiation and prostate cancer. © 2013 Japanese Cancer Association.

    To compare cancer mortality among A-bomb survivors exposed as children with cancer mortality among an unexposed control group (the entire population of Japan, JPCG). The subjects were the Hiroshima and Nagasaki A-bomb survivor groups (0-14 years of age in 1945) reported in life span study report 12 (follow-up years were from 1950 to 1990), and a control group consisting of the JPCG. We estimated the expected number of deaths due to all causes and cancers of various causes among the exposed survivors who died in the follow-up interval, if they had died with the same mortality as the JPCG (0-14 years of age in 1945). We calculated the standardized mortality ratio (SMR) of A-bomb survivors in comparison with the JPCG. SMRs were significantly higher in exposed boys overall for all deaths, all cancers, leukemia, and liver cancer, and for exposed girls overall for all cancers, solid cancers, liver cancer, and breast cancer. In boys, SMRs were significantly higher for all deaths and liver cancer even in those exposed to very low doses, and for all cancers, solid cancers, and liver cancer in those exposed to low doses. In girls, SMRs were significantly higher for liver cancer and uterine cancer in those exposed to low doses, and for leukemia, solid cancers, stomach cancer, and breast cancer in those exposed to high doses. We calculated the SMRs for the A-bomb survivors versus JPCG in childhood and compared them with a true non-exposed group. A notable result was that SMRs in boys exposed to low doses were significantly higher for solid cancer.

    Though a cold winter with snowfalls, in the fiscal year 1983, the number of the atomic-bomb sufferers using the Beppu Atomic-bomb Center (a medical hot spring) was large in January and February, 1984; throughout the fiscal year, the total number was about 3,800 persons. The diseases of the sufferers, mostly in locomotion organs, are such as osteoarthritis of spine, lame hip and knee arthropathy. Being the typical diseases for which hot spring treatment is good, the effect is clear, and those desiring to enter the Center twice in a year are increasing. The situation of usage of the Center from April, 1983, to March, 1984, is described.

    Review was made of the fourth medical examination and the actual state of health of the U.S. atomic-bomb (A-bomb) survivors. The number of survivors registered with the Committee of A-bomb Survivors residing in the U.S. as of the end of June 1983 in 592 (males 154, females 438), of whom 58.8% possess U.S. citizenship. Survivor's health handbooks issued to survivors under the Japanese A-bomb Survivors Medical Treatment Law are possessed by 29.2%, with female holders being about twice as numerous as males. Responses to the health survey questionnaire were received from 306. Complaints of subjective symptoms tended to be higher in the early entrants, and by place of examination, those of Honolulu had the higher rate. Those who underwent health examination numbered 305 (73 males and 232 females). RBC and hemoglobin value were higher in the U.S. survivors than in Hiroshima survivors. No abnormality was observed in 47.5%. The main abnormalities noted were obesity, hypertension, hyperlipidemia, ischemic heart disease, diabetes mellitus, hypothyroidism, and liver disease. Comparison of those who had received examination on two consecutive occasions in 1981 and 1983 and those who were examined for the first time in 1983 showed a decrease in the frequency of obesity and hypertension.

    We reviewed a series of 778 patients who had cataract surgery during the past 4 years at the Nagasaki Atomic Bomb Memorial Hospital. We evaluated the history of exposure to radiation by atomic bomb in 1945, axial length and state of refraction. All were born before 1945. The series comprised 263 males and 515 females. Their ages averaged 76.5{+-}8.6 years. History of exposure to radiation was present in 356 patients. The remaining 422 patients served as control. There was no difference in the type of cataract between the two groups. High myopia was present in 11 irradiated patients (3.2%) and in 24 patients in the control group (6.0%). The difference was not significant (p=0.083). There was no high myopia among 24 patients who were aged 18 years or less at the time of radiation and who were within 2 km from the epicenter. No difference was present regarding the axial length between the two groups or between both sexes. The present result is not definitive because ''irradiated group'' would include those with little or no exposure and because precise data has not been available about the dosis of radiation.

    In 1972 committees of the United Nations and the US National Academy of Sciencs emphasized the need for organ dose estimates on the Japanese atomic-bomb survivors. These estimates were then supplied by workers in Japan and the US, and they were used with the so-called T65D estimates of a survivor's radiation exposure to assess risk from radiation. Recently the T65D estimates have been questioned, and programs for reassessment of atomic-bomb radiation dosimetry have been started in Japan and the US. As a part of this new effort a mathematical analogue of the human body (or ''mathematical phantom''), to be used in estimating organ doses in adult survivors, is presented here. Recommendations on organ dosimetry for juvenile survivors are also presented and discussed. 57 refs., 10 figs., 6 tabs.

    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)

    Characteristic features of leukemia among atomic bomb survivors were studied. The ratio of a single leukemia type to all leukemias was highest for CML in Hiroshima, and the occurrence of CML was thought to be most characteristic for atomic bomb radiation induced leukemia. In the distribution of AML subtypes of FAB classification, there was no M3 cases in 1 Gy or more group, although several atypical AML cases of survivors were observed. Chromosome study was conducted using colony forming cells induced by hemopoietic stem cells of peripheral blood of proximal survivors. Same chromosome aberrations were observed in colony forming cells and peripheral blood of proximal survivors. (author).

    Characteristic features of the leukemia among atomic bomb survivors were studied. Dose estimates of atomic bomb radiation were based on T65D, but the new dosimetry system DS86 was used for some analyses. The ratio of a single leukemia type to all leukemias was highest for chronic myelogenous leukemia (CML) in Hiroshima, and the occurrence of CML was thought to be most characteristic to atomic bomb radiation induced leukemia. The threshold of CML occurrence in Hiroshima is likely to be between 0.5{approx}0.09 Gy. However, the threshold of acute leukemia appears to be nearly 1 Gy. In the distribution of acute myeloid leukemia (AML) subtypes by French-American-British classification, there was no M3 case in 1 Gy or more group, although several atypical AML cases of survivors were observed. Although aplastic anemia has not increased as a late effect of the atomic bomb radiation exposure, many atypical leukemia or other myeloproliferative diseases who had been diagnosed as aplastic anemia or its related diseases have been experienced among atomic bomb survivors. Chromosome study was conducted using colony forming cells induced by hemopoietic stem cells of peripheral blood of proximal survivors. Same chromosome aberrations were observed in colony forming cells and peripheral T-cells in several atomic bomb survivors. (author).

    Men exposed to the atomic bomb were screened for prostatic cancer in Nagasaki City, Japan. From 1983 to 1988, 2,421 subjects were examined. Of the 2,421 men, 12 (0.5%) prostatic cancer patients and 268 (11.1%) patients with benign prostatic hypertrophy requiring treatment were detected. Of the 12 prostatic cancer patients (stage B: 8, stage C: 3, and stage D: 1), 8 (67%) were suffering from early stage cancer. The measurement of serum acid phosphatase was not useful as a screening test for early stage prostatic cancer, since no patient with stage B disease had elevated acid phosphatase activity. The results of our study suggest that the following examination system would be useful for detecting early stage prostatic cancer; a digital rectal examination performed as an initial screening examination and when subjects are judged as needing further examinations, a second screening examination including digital palpation of the prostate, transrectal ultrasonography and an aspiration biopsy for cytological evaluation.

    A study of the epidemiology of proteinuria was conducted on about 5000 persons comprising a portion of the clinical sample under study at the Atomic Bomb Casualty Commission. In addition, data from previous examinations of similar samples were analyzed. Proteinuria was more common in Hiroshima than in Nagasaki. The rates for men and women did not differ within cities. Age-specific rates of proteinuria were peculiar, peaking in adolescence and old age. In the subjects under study proteinuria was frequently inconstant and usually represented excretion of less than 1.0 g of protein per day. Prior exposure to radiation as measured by distance from the hypocenter was correlated with increased proteinuria rates in 18-year-old subjects who were in utero ATB. Subjects exposed after birth did not show this tendency. It is unsettled whether radiation results in renal disease by increasing the subject's susceptibility to the usual causes of glomerulonephritis or by some more direct mechanism. Persons with proteinuria had higher mean blood pressures and serum urea nitrogen levels than controls and had other findings indicative of generalized cardiovascular-renal disease. Persons with thyroid disease had an increased risk of proteinuria whereas the converse was true of those with a history of treatment for peptic ulcer. Many other factors were tested for a relation to proteinuria, including family history of renal disease, socioeconomic status, urinary symptoms, ingestion of medications, physical findings, hemoglobin levels, height, weight, ABO blood groups, audiometry, vibrometry, and serum cholesterol levels. Although urinary symptoms were more common in persons with proteinuria, the findings in other areas were not sufficiently different to suggest meaningful relations. 20 references, 2 figures, 13 tables.

    Media reports of deaths and devastation produced by atomic bombs convinced people around the world that all ionizing radiation is harmful. This concentrated attention on fear of miniscule doses of radiation. Soon the linear no threshold (LNT) paradigm was converted into laws. Scientifically valid information about the health benefits from low dose irradiation was ignored. Here are studies which show increased health in Japanese survivors of atomic bombs. Parameters include decreased mutation,...

    This document contains 3 reports dealing with the delayed effects of radiation on the eyes of survivors of the atomic explosions in Hiroshima and Nagasaki. In the first study, 1000 persons who were listed as having been in the open and within two kilometers of the hypocenter at the time of the explosion were selected at random from the census files of the Atomic Bomb Casualty Commission for study. In addition, 231 others, comprising the total available number of surviving persons listed at present in the census files as having been within one kilometer of the hypocenter, were examined, as were several hundred others who were contacted through newspaper publicity, referrals from local ophthalmologists, or through hearsay. The survey resulted in bringing in persons having, or having had, a variety of ocular conditions. Those connected with the atomic bomb included the following diagnoses; multiple injuries of eyes and eyelids; keratoconjunctivitis from ultraviolet and ionizing radiations; thermal burn of the cornea and of the retina; retinitis proliferans; and radiation cataracts. The cataracts were the only delayed manifestations of ocular injury from the atomic bomb. The second paper is a case report of a histopathologic study of atomic bomb radiation cataract. The third paper presents the results of medical examinations of survivors having radiation induced cataracts. 32 references, 8 figures. (DMC)

    During 22 years from 1968 through 1989, 538 A-bomb survivors were operated on for gastric cancer, accounting for 30.9% of 1,741 surgical cases of gastric cancer during that period. To determine whether age at the time of exposure to A-bombing might influenced the occurrrence of gastric cancer, these A-bomb survivors were compared with 1,138 other non-exposed gastric cancer patients. According to age at the time of exposure, the 538 A-bomb survivors were divided into those under the age of 19 (118), those in their twenties (134), those in their thirties (178), and those over the age of 40 (108). The largest number of gastric cancer was those in their thirties at the time of exposure, followed by the twenties, 19 years or less, and 40 years or more in the exposed group. The younger A-bomb survivors were at the time of exposure, the earlier gastric cancer occurred. These findings were common to the non-exposed group. Postoperative 5-year survival rate was 72.0% in A-bomb survivors aged 19 years or less at the time of exposure, which was better than the other age groups. This may be explained by active participation in health examination for A-bomb survivors. (N.K.).

    Immunologic parameters were studied among survivors of the 1945 atomic bombs who now reside in the United States. Of all known survivors living in the US, about 40% (n = 189) participated in this study. Of those survivors on whom radiation exposure information was available (n = 168), 96% were exposed to less than 50 rad at the time of the bomb (ATB). Survivors were divided into two groups; those exposed to varying low doses of radiation (S/sub +/ group, exposed at less than or equal to 2500 m from the hypocenter) were compared with those exposed to 0 rad (S/sub 0/ group, exposed at > 2500 m from the hypocenter). Of the former group, 92% were exposed to less than 100 rad and 89% to less than 50 rad ATB. Cellular immune responses, including natural cell-mediated cytotoxicity (NCMC), interferon production, and the mitogenic response to PHA, tended to be higher among S/sub +/ individuals, although only the different for NCMC was statistically significant. This was suggestive of a trend which was consistent with the higher serum interferon levels and lower frequencies of detectable immune complexes and antimitochondrial antibodies among the S/sub +/ group, although these differences were not statistically significant.

    We report a case of successfully treated Listeria monocytogenes (Lm) meningitis in a atomic bomb survivor receiving steroid therapy for aplastic anemia. The patient was a 62-year-old woman and the past medical history included hypothyroidism due to radioiodide therapy for Basedow disease, breast cancer, aplastic anemia, steroid-induced diabetes mellitus, and pulmonary tuberculosis. At the time of onset, she was receiving corticosteroid, anabolic steroid, an H{sub 2}-blocker (famotidine), and other medication. Since she developed symptoms of meningitis when she visited our hospital for regular medical check-up for aplastic anemia, she was hospitalized and given antibiotic therapy, including ABPC, without delay. With this effective antibiotic therapy and successful management of the co-existing medical conditions, she was cured except for being a little euphoric. Lm meningitis is known to occur in aged and immunocompromised patients. Since most of the atomic bomb survivors are now aged and the prevalence of malignancy, diabetes mellitus, and other diseases which cause immunodeficiency have been rising year by year, Lm meningitis is one of the emergency neurologic conditions whose diagnosis should not be delayed in this population.

    The purpose of this study is to analyze various laboratory indicators of inflammation measured in atomic bomb survivors. Subjects are 6304 survivors who underwent inflammatory tests at RERF between 1998 and 1992 and whose radiation doses (DS86) are available. Inflammatory tests include leukocyte counts, neutrophil counts, erythrocyte sedimentation rate, corrected erythrocyte sedimentation rate, alpha 1 globulin, alpha 2 globulin, and sialic acid. Adjusting for age, sex, smoking, and city of residence, regression analysis was conducted. Regression analysis, adjusted for age, sex, smoking, and city of residence showed statistically significant associations with radiation dose for leukocyte counts (71.0 /mm{sup 3}/Gy, p=0.00151), erythrocyte sedimentation rate (1.58 mm/hour/Gy, p=0.0001), corrected erythrocyte sedimentation rate (1.14 mm/hour/Gy, p=0.0001), alpha 1 globulin (0.0057 g/dl/Gy, p=0.0001), alpha 2 globulin (0.0128 g/dl/Gy, p=0.0001), and sialic acid (1.2711 mg/dl/Gy, p=0.0001), but not for neutrophil counts (29.9 /mm{sup 3}/Gy, p=0.1729). Standardized scores combining results from these seven inflammatory tests showed significant associations with radiation dose both for persons with and without inflammatory disease, and for two inflammatory conditions in particular, chronic thyroiditis and chronic liver disease. In analyses of data from 403 AHS patients, in whom both inflammation indicators and T-cell ratios were measured, increased inflammation correlates with decreases in CD4 T-cells. Since the laboratory indicators of inflammation that we studied are not specific for particular clinical diseases, the implication of their dose-response-pattern is hard to interpret. The general occurrence of infectious diseases in survivors is not related to radiation dose. Such a relationship does exist, however, for other diseases in which infection may play an etiologic role. Virologic studies in A-bomb survivors have suggested dose-response alterations in immune

    Radiation-induced cancer mortality rates among atomic bomb survivors with doses of at least 100 rad and patients with ankylosing spondylitis given X-ray therapy have been compared for the first time. The estimated average mean bone marrow dose for the spondylitics is more than twice that for atomic bomb survivors, and yet spondylitics experienced only half the risk of radiation-induced leukemia of atomic bomb survivors. For sites that were heavily irradiated in the spondylitics, provisional estimates indicate comparable doses in the two studies, and similar levels of cancer risk were observed. For these sites, when information from the studies was combined, there were statistically significant excesses for cancers of the esophagus, stomach, lung, and ovaries, multiple myeloma, other lymphomas, and tumors of the spinal cord and nerves. Very high relative risks (RR's) for tumors of the spinal cord and nerves were observed in both studies. For sites that were lightly irradiated in the spondylitics, in addition to previously documented sites, there was a statistically significant excess of cancers of the liver and gallbladder among atomic bomb survivors. A previous subdivision of cancer sites into radiosensitive and other tissues was not supported by the atomic bomb survivor data. Changes in the rates of radiation-induced cancers with age at exposure and time since exposure were studied and compared with the use of generalized linear modeling of the RR's and also by examination of the excess mortality rates. The level of agreement between the two studies was high; provided it is accepted that the reduced level of leukemia risk in the spondylitics is due to cell sterilization, no inconsistencies were found.

    Hepatitis C and B virus (HCV, HBV) infection plays a crucial role in the etiology of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma, which have been reported to increase with radiation dose among the atomic bomb survivors. The purpose of this study is to investigate whether radiation exposure altered the prevalence of hepatitis virus infection or accelerated the progress toward chronic hepatitis after hepatitis virus infection. Levels of serum antibody to hepatitis C virus (anti-HCV), HBs antigen (HBsAg), and anti-HBs antibody (anti-HBs) were measured for 6,121 participants in the Adult Health Study of atomic bomb survivors in Hiroshima and Nagasaki. No relationship was found between anti-HCV prevalence and radiation dose, after adjusting for age, sex, city, history of blood transfusion, acupuncture, and family history, but prevalence of anti-HCV was significantly lower overall among the radiation-exposed people (relative prevalence 0.84, p=0.022) compared to people with estimated radiation dose 0 Gy. No significant interaction was found between any of the above mentioned risk factors and radiation dose. People with anti-HCV positive had 13 times higher prevalence of chronic liver disease than those without anti-HCV. However, the radiation dose response for chronic liver disease among anti-HCV positive survivors may be greater than that among anti-HCV negative survivors (slope ratio 20), but the difference was marginally significant (p=0.097). Prevalence of HBsAg increased with whole-body kerma. However, no trend with radiation dose was found in the anti-HBs prevalence. In the background, prevalence of chronic liver disease in people with HBsAg-positive was approximately three times higher that in those without HBsAg. No difference in slope of the dose was found among HBsAg positive and negative individuals (slope: HBsAg positive 0.91/Gy, HBsAg negative 0.11/Gy, difference p=0.66). In conclusion, no dose-response relationship was found between

    Since 1950 about 87 000 A-bomb survivors from Hiroshima and Nagasaki have been monitored within the framework of the Life Span Study, to quantify radiation-induced late effects. In terms of incidence and mortality, a statistically significant excess was found for leukemia and solid tumors. In another major international effort, neutron and gamma radiation doses were estimated, for those survivors (Dosimetry System DS02). Both studies combined allow the deduction of risk coefficients that serve as a basis for international safety regulations. As an example, current results on all solid tumors combined suggest an excess relative risk of 0.47 per Sievert for an attained age of 70 years, for those who were exposed at an age of 30 years. After exposure to an effective dose of one Sievert the solid tumor mortality would thus be about 50% larger than that expected for a similar cohort not exposed to any ionizing radiation from the bombs.

    Ionizing radiation released by the atomic bombs at Hiroshima and Nagasaki, Japan, in 1945 caused many long-term illnesses, including increased risks of malignancies such as leukemia and solid tumours. Radiation has demonstrated genetic effects in animal models, leading to concerns over the potential hereditary effects of atomic bomb-related radiation. However, no direct analyses of whole DNA have yet been reported. We therefore investigated de novo variants in offspring of atomic-bomb survivors by whole-genome sequencing (WGS). We collected peripheral blood from three trios, each comprising a father (atomic-bomb survivor with acute radiation symptoms), a non-exposed mother, and their child, none of whom had any past history of haematological disorders. One trio of non-exposed individuals was included as a control. DNA was extracted and the numbers of de novo single nucleotide variants in the children were counted by WGS with sequencing confirmation. Gross structural variants were also analysed. Written informed consent was obtained from all participants prior to the study. There were 62, 81, and 42 de novo single nucleotide variants in the children of atomic-bomb survivors, compared with 48 in the control trio. There were no gross structural variants in any trio. These findings are in accord with previously published results that also showed no significant genetic effects of atomic-bomb radiation on second-generation survivors.

    Full Text Available The effect of atomic bomb radiation exposure on the survivors and their children has been a worrisome problem since soon after the 1945 Hiroshima and Nagasaki bombings. Researchers have examined physical and genetic effects; however, no research has focused on second-generation survivors’ (SGS psychological effects. Consequently, this study shed light on the SGS’ experience of discrimination and prejudice and their anxiety concerning the genetic effects of radiation exposure. This study utilized semi-structured interviews with 14 SGS (10 women, mean age = 56 ± 6.25 years, range = 46–68 years. Data were analyzed using a modified version of the grounded theory approach. Three categories were extracted: low awareness as an SGS, no health anxiety regarding the effect of radiation, and health anxiety regarding the effect of radiation. The results did not reveal that SGS who grew up in the bombed areas experienced discrimination or prejudice. They had little health anxiety from childhood to adolescence. In this study, some of the SGS developed health anxiety about their third-generation children, but only among female participants. Perhaps the transgenerational transmission of anxiety concerning the genetic effects of radiation exposure causes stress, particularly among women with children. However, a change was seen in adulthood health anxiety regarding the effects of radiation, suggesting the possibility that changes in the psychological experiences of SGS can be observed throughout their lifetimes and that their own health status, and that of their children, the third-generation survivors, affects their health anxiety regarding radiation.

    As two cytogenetic parameters of radiation exposure, the frequency of micronucleus in erythroblasts, lymphocytes and red cells (Howell-Jolly body) as well as chromosome aberrations in bone marrow cells and in lymphocytes were studied in 24 thorotrast patients and in 32 atomic bomb (A-bomb) survivors who were exposed within one kilometer from the Hiroshima hypocenter. The incidence of both micronucleus and chromosome aberrations in these two exposed groups were significantly higher than that in non-exposed controls. So that these two parameters are useful guide for evaluating the residual effects of radiation, especially on hematopoietic cells. Because of its simple procedures, micronucleus test is also helpful as screening for prediction of chromosome aberrations. The characteristics of lymphocyte chromosome aberrations differed considerably between thorotrast patients and A-bomb survivors; the incidence of unstable type aberrations and intracellular complexity of chromosome aberrations were much higher in the former group. The incidence of micronucleus in erythroblasts and lymphocytes was also higher in thorotrast patients. Such differences are attributable to the differences in the radiation quality (..cap alpha..-ray or ..gamma..-ray+neutron) and in the mode of exposure (persistent or single) of these two groups.

    The twelfth medical examination of atomic bomb survivors residing in North America, was conducted in San Francisco and Seattle from May 20 through June 2 1999, and in Los Angeles and Hawaii from June 9 through 23 1999, The examination included an interview, measurement of height, weight, and blood pressure, an ECG, urine and stool tests, blood tests, a physical examination, examination of the breast, thyroid, and rectum by a surgeon, and screening for uterine cancer and a gynecological interview and examination by an obstetrician and gynecologist. The total confirmed number of A-bomb survivors residing in North America as of the end of June 1999 was 1076. Of the 1062 survivors that remained after excluding the 14 subjects whose survey was incomplete, 279 males and 654 females had been exposed in Hiroshima, and 10 males and 119 females in Nagasaki. The peak age at the time of exposure in both sexes was 15-19 years, followed by 10-14 years. The number of survivors exposed <2000 m from the hypocenter was 236, accounting for 21.9% of the total. The confirmed number of survivors exposed in utero was 26. The survivors' age (mean {+-}S.D.) was: 69.0{+-}8.69 years; males, 68.4{+-}80.5 years; females, 69.2{+-}8.91 years. A total of 414 survivors were examined (male 129; female 285; mean age 68.0 years). Approximately 80% of the examinees had experienced at least one general symptom. Many still complain of symptoms that suggest possible posttraumatic stress disorder as a result of exposure to the A-bomb. It will be necessary to consider providing mental health care by psychiatrists beginning with the next examination. The prevalence of life-style diseases has been gradually increased with age. A previous history of cancer was found in 9.2% of the examinees. The most prevalent was of breast cancer, followed by malignant tumors of the colon, rectum, uterus, brain, stomach, and thyroid. The need for cancer screening and promotion of life-style education was keenly felt. (K.H.)

    During a one-month period from June 13 through July 13, 1989, the seventh medical examination was conducted at five cities, including San Francisco, Los Angeles, Seattle, Wailuku and Honolulu, for A-bomb survivors residents in North America. Nine hundred and eighteen A-bomb survivors, including 21 living in Canada, were confirmed, consisting of 234 men and 684 women as of the end of July 1989. The number was increased by 167, compared with that as of the end of July 1987. During the past three years, there were 40 deaths; and 878 A-bomb survivors (223 men and 655 women) are still alive. Ninety percent of the survivors came from Hiroshima. U.S. nationality was seen in 61% and Japanese nationality with permanent U.S. residency rights was seen in 32%. The majority (39%) of the A-bomb survivors were in their fifties, with an average age of 59.4 years. The survivors were residing in 26 states in the USA and in 3 provinces in Canada. The acquisition rate of the A-bomb survivors' health handbook was 52%. Four hundred and six A-bomb survivors participated in the medical examination, including one male and 8 female children born to A-bomb survivors. Questionnaire survey revealed a history of surgical resection for cancer in 21 survivors. Subjective symptoms included complete exhaustion or fatigue, heat intolerance, loss of vigor, and numbness of the body. Overall evaluation revealed the necessity of medical treatment or observation in 71%. This was independent of exposure status. Hypertension was the most common (27%), followed by obesity, hyperlipidemia, heart disease, and diabetes mellitus. Malignant tumors were seen in 9 survivors, consisting of 3 with breast cancer, 2 with colorectal cancer, and single survivors with lung cancer, Hodgkin's disease, cervical cancer, or hepatoma. Only 29% of them have had finantial guarantee for their health management according to the Japanese law. (N.K.).

    After colonizing Korea, Japan invaded China, and subsequently initiated the Pacific War against the United States, Britain, and their allies. Towards the end of the war, U.S. warplanes dropped atomic bombs on Hiroshima and Nagasaki, which resulted in a large number of Koreans who lived in Hiroshima and Nagasaki suffering from the effects of the bombs. The objective of this paper is to examine the history of Korea atomic bomb victims who were caught in between the U.S., Japan, the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea).

    It has been postulated that radiation induces breast cancers in atomic bomb (A-bomb) survivors. Oncogene amplification is an important mechanism during breast carcinogenesis and also serves as an indicator of genomic instability (GIN). The objective of this study was to clarify the association of oncogene amplification in breast cancer in A-bomb survivors with radiation exposure. In total, 593 breast cancers were identified in A-bomb survivors from 1968 to 1999, and the association between breast cancer incidence and A-bomb radiation exposure was evaluated. Invasive ductal cancers from 67 survivors and 30 nonsurvivors were analyzed for amplification of the HER2 and C-MYC genes by fluorescence in situ hybridization, and expression levels of hormone receptors were analyzed by immunostaining. The incidence rate increased significantly as exposure distance decreased from the hypocenter (hazard ratio per 1-km decrement, 1.47; 95% confidence interval [95% CI], 1.30-1.66). The incidence of HER2 and C-MYC amplification was increased significantly in the order of the control group, the distal group (P = .0238), and the proximal group (P = .0128). Multivariate analyses revealed that distance was a risk factor for the coamplification of C-MYC and HER2 in breast cancer in survivors (odds ratio per 1-km increment, 0.17; 95% CI, 0.01-0.63). The histologic grade of breast cancers became significantly higher in the order of the control group, the distal group, and the proximal group and was associated with oncogene amplifications. The current results suggested that A-bomb radiation may affect the development of oncogene amplification by inducing GIN and may be associated with a higher histologic grade in breast cancer among A-bomb survivors.

    Ionizing radiation (IR) is a major source of cellular damage and the immediate cellular response to IR has been well characterized. But the long-term impact of IR on cell function and its relationship with aging are not known. Here, we examined the IR effects on telomere length and other biomarkers 50 to 68 years post-exposure (two time points per person) in survivors of the atomic bombing at Hiroshima during WWII. We found that telomere length of leukocytes was inversely correlated with the dose of IR (p=0.008), and this effect was primarily found in survivors who were exposed at younger ages; specifically those <12 years old (p=0.0004). Although a dose-related retardation of telomere shortening with age was observed in the cross-sectional data, longitudinal follow-up after 11 years did not show IR exposure-related alteration of the rate of telomere shortening with age. In addition, IR diminished the associations between telomere length and selected aging biomarkers that were observed in survivors with no dose. These included uric acid metabolism, cytokines, and blood T cell counts. These findings showed long-lasting detrimental effects of IR on telomere length of leukocytes in both dose- and age-at-exposure dependent manner, and on alterations of biomarkers with aging.

    Autopsy findings of 652 fetuses whose parents or one parent were exposed to the Atomic Bomb (F[sub 1]) and 115 fetuses which had one or two grandparents exposed (F[sub 2]) were compared with that of 8570 fetuses whose parents were not exposed (control). The F[sub 1] fetuses have been collected since 1963 and F[sub 2] fetuses since 1971 voluntarily in Hiroshima. The findings were classified according to the types of delivery and to the distances away from the hypocenter where the parents and grandparents were exposed. Many normal cases in the group of artificial abortions and many malformations and pathological findings in the group of spontaneous abortions were found in both groups of F[sub 1] and F[sub 2]. The malformations were cardiovascular, central nervous and urogenital system, quantitatively in that order, in both groups of F[sub 1] and F[sub 2]. Although there were a few cases of cystic kidney and chondrodystrophy which belong to autosomal dominant and osteogenesis imperfecta which belong to autosomal recessive, these cases were not correlated with the distance. Most cases of malformation which belong to the multifactorial inheritance were found in each organ. No peculiar malformation was found in the groups of F[sub 1] and F[sub 2]. (author).

    In October 9 - 31, 1986, the second medical examination for A-bomb survivors was undertaken in Brazil, Argentina, Paraguay, Bolivia, and Peru. Among 173 recognized A-bomb survivors in the five countries, 126 (73 %) participated in the examination, consisting of 61 men and 65 women. Seventy-eight A-bomb survivors came from Hiroshima and 48 from Nagasaki. The average age was 55.6 +- 9.7 years for men and 56.5 +- 9.8 years for women. The acquisition rate of ''Survivor's Health Handbook'' was 34 %. Gastric cancer was observed in two survivors and cervical cancer in one survivor. Major subjective symptoms were: fatigue, sensation of paralysis, heat intolerance, decreased physical strength, and itching. None of the abnormal findings were observed in 33 %. The incidence of hypertension, obesity, cardiac disease, and liver disease was high. The incidence of hypercholesteremia and diabetes mellitus was lower than that in the USA. (Namekawa, K.).

    The thirteenth medical examination of A-bomb survivors resident in North America was carried out from June 13th through June 27th and from July 12th through July 26th, 2001, in the cities of Los Angeles, San Francisco, Seattle, and Honolulu. The total number of those who underwent the thirteenth medical examination was 399, 53 of whom were second-generation A-bomb survivors. As the survivors in North America are advancing in age, the average age of the examinee was 69.5 years. The examination items included an interview, clinical and physical examinations, electrocardiography (E.C.G.), and blood, urine, and stool tests. The review of the medical history showed that hypertension was the most frequent in the survivors examined, with the prevalence of 39.3%. Previous history of malignant tumors was observed in 13.6% of the survivors examined, with major sites being the mammary gland, uterine, and colon. As a result of the blood test, 9.5% of the survivors examined were diagnosed as diabetic, and hypercholesterolemia was found in 32.1% of the survivors examined. Latent hypothyroidism was found in 18.5% of the survivors examined. No disease or examination finding showed a clear relation with exposure status. A report providing the results of the medical examination and necessity of undergoing closer examination and receiving medical treatment, if any, was mailed to each examinee. (author)

    This study compared findings of chronic myelocytic leukemia (CML) in A-bomb survivors (n=8) developing CML within 10 years after the bombing and in non-exposed CML patients (n=14). Both Ph{sup 1} chromosomes and bcr rearrangement were observed in all patients in both exposed and non-exposed groups. There was no significant difference in distribution sites of bcr rearrangement between the groups. These results suggest that bcr-abl chimera mRNA and chimera protein associated with Ph{sup 1} chromosomes have an important role in the development of CML among A-bomb survivors, as well as among non-exposed patients.

    Retrospective estimation of the doses received by atomic bomb (A-bomb) survivors by cytogenetic methods has been hindered by two factors: One is that the photon energies released from the bomb were widely distributed, and since the aberration yield varies depending on the energy, the use of monoenergetic 60Co gamma radiation to construct a calibration curve may bias the estimate. The second problem is the increasing proportion of newly formed lymphocytes entering into the lymphocyte pool with increasing time intervals since the exposures. These new cells are derived from irradiated precursor/stem cells whose radiosensitivity may differ from that of blood lymphocytes. To overcome these problems, radiation doses to tooth enamel were estimated using the electron spin resonance (ESR; or EPR, electron paramagnetic resonance) method and compared with the cytogenetically estimated doses from the same survivors. The ESR method is only weakly dependent on the photon energy and independent of the years elapsed since an exposure. Both ESR and cytogenetic doses were estimated from 107 survivors. The latter estimates were made by assuming that although a part of the cells examined could be lymphoid stem or precursor cells at the time of exposure, all the cells had the same radiosensitivity as blood lymphocytes, and that the A-bomb gamma-ray spectrum was the same as that of the 60Co gamma rays. Subsequently, ESR and cytogenetic endpoints were used to estimate the kerma doses using individual DS02R1 information on shielding conditions. The results showed that the two sets of kerma doses were in close agreement, indicating that perhaps no correction is needed in estimating atomic bomb gamma-ray doses from the cytogenetically estimated 60Co gamma-ray equivalent doses. The present results will make it possible to directly compare cytogenetic doses with the physically estimated doses of the survivors, which would pave the way for testing whether or not there are any systematic trends

    The atomic bomb survivors emigrating in the South America were 189 in total (160 in Brazil, 4 in Paraguay, 8 in Bolivia, 14 in Argentina and 3 in Peru) in November, 1998. Ninety-three persons (49%) took a medical examination (72 in Brazil, 3 in Paraguay, 6 in Bolivia, 9 in Argentina and 3 in Peru). The mean age was 68.6 years in male, and 68.1 years in female. They had hypertension (21.5%), diabetes (8.6%), cancer (6.5%), heart disease (5.4%), and thyroid gland diseases (4.3%). The subjective symptoms with high frequency were complete exhaustion or fatigue (58.1%), loss of vigor (55.9%), heat intolerance (49.5%) and numbness or tingling (47.1%). Electrocardiogram abnormality, total protein decrement, hypercholesterolemia and corpulence were almost the same as the last time. There was no change of a ratio of persons who needed tests on treatments. (K.H.)

    Thirty seven years ago, 6 August 1945 marks the date of the first atomic bombing never experienced in human history. It was dropped on Hiroshima and this was followed by a second bombing three days later on Nagasaki. The total deaths following exposure to the bomb by the end of 1945 totalled 140,000 (+/- 10,000) in Hiroshima and 70,000 (+/- 10,000) in Nagasaki. The present article described and outline of the physical effects of the atomic bomb and injury to the human body by exposure to the bomb.

    The results of medical follow-up of 78 A-bomb survivors who had been exposed to A-bomb at the site within 500 m of the hypocenter were reviewed. In those survivors, who had exposure at an average of 28.6 years old, 75% had very severe, acute radiation-injuries such as trauma, depilation, vomiting, diarrhea, and hemorrhage. Physical examination revealed high incidences of ophthalmologic abnormalities, traumatic scar, and deformation of the lower extremities. Clinical findings included abnormal roentgen pictures of the stomach and the duodenum, and a rather high incidence of PPD negative cases. Functional and morphological abnormalities are often found in the circulatory system, eyeball, digestive organs, and joints. One survivor had an average of 2.5 diseases to be treated. Hematological observation revealed a high incidence of increased EB virus antibody, and a high incidence of abnormalities at the chromosomal level in T and B lymphocytes, and myelocytes. Of 78 survivors, 13 died in the subsequent 10 years, 4 of them had had cancer such as leukemia and lung cancer. Implication of the chromosome in the cancerization process in these cases was discussed.

    Full text of the publication follows: Thyroid cancer is one of the malignancies most strongly associated with ionizing radiation in humans. Epidemiology studies of atomic bomb (A-bomb) survivors have indicated that excess relative risk of papillary thyroid cancer per Gy was remarkably high in the survivors. We therefore aim to clarify mechanisms linking A-bomb radiation exposure and development of papillary thyroid cancer. Toward this end, we intend to clarify characteristics of gene alterations occurring in radiation-associated adult-onset papillary thyroid cancer from the Life Span Study cohort of A-bomb survivors. We have thus far found that with increased radiation dose, papillary thyroid cancer cases with chromosomal rearrangements (mainly RET/PTC rearrangements) significantly increased and papillary thyroid cancer cases with point mutations (mainly BRAF-V600E) significantly decreased. Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

    The scientific community faces important discussions on the validity of the linear no-threshold (LNT) model for radiation-associated cardiovascular diseases at low and moderate doses. In the present study, mortalities from cerebrovascular diseases (CeVD) and heart diseases from the latest data on atomic bomb survivors were analyzed. The analysis was performed with several radio-biologically motivated linear and nonlinear dose-response models. For each detrimental health outcome one set of models was identified that all fitted the data about equally well. This set was used for multi-model inference (MMI), a statistical method of superposing different models to allow risk estimates to be based on several plausible dose-response models rather than just relying on a single model of choice. MMI provides a more accurate determination of the dose response and a more comprehensive characterization of uncertainties. It was found that for CeVD, the dose-response curve from MMI is located below the linear no-threshold model at low and medium doses (0-1.4 Gy). At higher doses MMI predicts a higher risk compared to the LNT model. A sublinear dose-response was also found for heart diseases (0-3 Gy). The analyses provide no conclusive answer to the question whether there is a radiation risk below 0.75 Gy for CeVD and 2.6 Gy for heart diseases. MMI suggests that the dose-response curves for CeVD and heart diseases in the Lifespan Study are sublinear at low and moderate doses. This has relevance for radiotherapy treatment planning and for international radiation protection practices in general.

    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.)

    The 11th medical examination of A-bomb survivors was conducted in 1997. Two medical teams conducted health examinations in Los Angeles and Seattle, and in San Francisco and Hawaii, respectively. The total number of A-bomb survivors resident in North America as of the end of July 1997 was 1,060, an increase of 17 over that confirmed in 1995. The number of survivors exposed <2,000-m from the hypocenter was 234, accounting for 22.1% of the total. The confirmed number of in-utero exposed survivors was 26. As to the past medical history information, breast cancer, thyroid cancer, and heart disease were frequently observed in the <2,000-m group. Frequent subjective symptoms include complete exhaustion or fatigue, loss of vigor, blurring of vision, itching of the skin, which were reported in more than 40% of the survivors. The frequencies of nocturia, nervousness, severe headache, and excessive sweating in cold weather were higher in the <2,000-m group. Chest pain was seen frequently in the <2,000-m group for males, but no difference was observed in females. Nocturia was observed in more than half of the males in the <2,000-m group. There were 99 cases (22.8%) with fasting plasma glucose level of 110 mg/dl or above, consisting of 39 males (32.0%) and 60 females (19.2%). Abnormal HbA1c levels were observed in 33 cases (7.6%), including 12 males (9.8%) and 11 females (6.7%). The proportion of cases with abnormal HbA1c levels was higher in males. No difference by exposure status was observed either for fasting plasma glucose or HbA1c. The disease of the highest prevalence was hyperlipidemia (57.4%), followed by hypertension (35.0%), obesity (27.2%), liver disease (21.9%), thyroid disease (20.0%), gastrointestinal disease (20.7%), heart disease (13.4%) and urological disease (12.9%). Malignant tumors were observed in two cases in L.A., two in Seattle, and one in S.F. Cancer will be important issue in the future examinations. (K.H.)

    The Life Span Study (LSS) on 93,741 survivors (fixed cohort) and the Open City Study (OCS) on all survivors (unfixed) irrespective of whether they belonged to LSS or not, have been conducted in parallel over 45 years to ensure reliable case detection. We adopted the FAB classification for acute leukemias and for exposure dose of individual survivors, the new dosimetry system 1986 (DS86). In LSS, 221 leukemia cases were analysed. There was strong evidence of radiation-induced risks for acute myeloid leukemia (AML), acute lymphoid leukemia (ALL) and chronic myeloid leukemia (CML), but not for adult T-cell leukemia and chronic lymphocytic leukemia. There was also significant difference between three major types with respect to the effects of age at bombing and sex, and in the temporal pattern of the elevated risks. For AML the dose response function was non-linear, whereas there was no evidence against linearity for ALL and CML. The hypothesis of a 0.5 Gy threshold could be rejected for three major types of leukemia. Excess Absolute Risk (EAR) estimates in cases per 10,000 Person Year Sievert (PYSv) were 0.6, 1.1, 0.9 for ALL, AML and CML, respectively. The corresponding relative risk at 1.0 Sv were 9.1, 3.3, 6.2, respectively. Although childhood exposure <15 age at bombing apparently induced three major types, the age-related highest risk was observed for ALL. In OCS, 413 cases with DS86 estimates were used for analysis. Type specific incidence rates were calculated indirectly by using the over all incidence of leukemia from LSS data and multiplying these values by the corresponding proportions of cases in OCS. In conjunction with LSS data, the effects of radiation were significantly greater on the incidences of ALL and CML than on that of AML. In the high dose group there was a strong evidence for shorter incubation time and faster decline of elevated risk for ALL and CML than for AML. AML risk was apparently persistent through 1980.

    The psychological state of middle aged and elderly atomic bomb survivors was analyzed by GHQ, which had been done from September to November, 1992. Subjects were 1,399 Nagasaki survivors of the average age of 61.3 y and 1,054 non-irradiated people of 62.2 y living in the countryside of Nagasaki prefecture as the control. Analyses were performed with {chi} square method and t-test. When the subordinate measure derived from factor analysis of GHQ was compared with that of the control group, the score possibly attributable to anxiety reaction to the stress was significantly higher in the survivors. However, the two scores attributable to obstacle in personal relations and to avoidance of social activities were significantly lower, which suggested that the survivors are able to have rich personal and social interactions. Besides, it was suggested that the GHQ score was increased possibly by anxiety for the future in the essential part of life such as loss of feeling of healthiness and dissatisfaction for the present life conditions. It was confirmed that systematic and continuous examinations are necessary from the bio-psycho-social viewpoint. (H.O.)

    A little over three years after assuming the directorship of the Los Alamos Scientific Laboratory, Norris Bradbury returned to his alma mater, Pomona College, and delivered one of his first extended speeches regarding the atomic bomb. Bradbury noted that although the atomic bomb had brought a “peace of kind,” ending World War II, the bomb also had become, without much thought, a “factor in the political, military, and diplomatic thinking of the world.” Bradbury hoped his speech, given to both the faculty and student body of Pomona, would give his audience a foundation on which to assess and understand the new world the bomb had ushered into existence. Bradbury’s talk was quickly printed an distributed by Pomona College and, later, reprinted in The Physical Review (Volume 75, No. 8, 1154-1160, April 15, 1949). It is reprinted here, for a third time, as a reminder of the early days of Los Alamos and its role in international affairs. "Slightly more that three years ago, this country brought to an end the most catastrophic war in history. The conflict had been characterized by an unremitting application of science to the technology of destruction. The final use of the atomic bomb, however, provided a climax so striking that the inevitable nature of future wars was illustrated with the utmost clarity. Peace of a kind followed the first military use of atomic weapons, but international understanding did not, and the atomic bomb became a factor in the political, military, and diplomatic thinking of the world. Where do we now stand in all this? What are the costs and the rewards? Where are we going? These are some of the things that I would like to discuss with you this morning."

    Analyses of the Life Span Study (LSS) of Japanese atomic bombing survivors have routinely incorporated corrections for additive classical measurement errors using regression calibration. Recently, several studies reported that the efficiency of the simulation-extrapolation method (SIMEX) is slightly more accurate than the simple regression calibration method (RCAL). In the present paper, the SIMEX and RCAL methods have been used to address errors in atomic bomb survivor dosimetry on solid cancer and leukaemia mortality risk estimates. For instance, it is shown that using the SIMEX method, the ERR/Gy is increased by an amount of about 29 % for all solid cancer deaths using a linear model compared to the RCAL method, and the corrected EAR 10{sup -4} person-years at 1 Gy (the linear terms) is decreased by about 8 %, while the corrected quadratic term (EAR 10{sup -4} person-years/Gy{sup 2}) is increased by about 65 % for leukaemia deaths based on a linear-quadratic model. The results with SIMEX method are slightly higher than published values. The observed differences were probably due to the fact that with the RCAL method the dosimetric data were partially corrected, while all doses were considered with the SIMEX method. Therefore, one should be careful when comparing the estimated risks and it may be useful to use several correction techniques in order to obtain a range of corrected estimates, rather than to rely on a single technique. This work will enable to improve the risk estimates derived from LSS data, and help to make more reliable the development of radiation protection standards. (orig.)

    Breast cancer risk from radiation exposure has been analyzed in the cohort of Japanese a-bomb survivors using empirical models and mechanistic two-step clonal expansion (TSCE) models with incidence data from 1958 to 1998. TSCE models rely on a phenomenological representation of cell transition processes on the path to cancer. They describe the data as good as empirical models and this fact has been exploited for risk assessment. Adequate models of both types have been selected with a statistical protocol based on parsimonious parameter deployment and their risk estimates have been combined using multi-model inference techniques. TSCE models relate the radiation risk to cell processes which are controlled by age-increasing rates of initiating mutations and by changes in hormone levels due to menopause. For exposure at young age, they predict an enhanced excess relative risk (ERR) whereas the preferred empirical model shows no dependence on age at exposure. At attained age 70, the multi-model median of the ERR at 1 Gy decreases moderately from 1.2 Gy{sup -1} (90% CI 0.72; 2.1) for exposure at age 25 to a 30% lower value for exposure at age 55. For cohort strata with few cases, where model predictions diverge, uncertainty intervals from multi-model inference are enhanced by up to a factor of 1.6 compared to the preferred empirical model. Multi-model inference provides a joint risk estimate from several plausible models rather than relying on a single model of choice. It produces more reliable point estimates and improves the characterization of uncertainties. The method is recommended for risk assessment in practical radiation protection. (orig.)

    The health examination for A-bomb survivors by national, prefectural and city administrations was described and discussed on its general concept, history, time change of examinee number, improvement of examination, prevalence of individual diseases, significance of cancer examinations, examinees` point of view and future problems. Subjects were the survivors living in Hiroshima city: in 1994, their number was 100,188, whose ages were 63 y in average for males consisting of 39.5% and 67 y for females of 60.5%. The examination was begun in 1957 on the law for medical care for the survivors firstly and then systematically in 1961. From 1965, it was performed 4 times a year, and in 1988, one examination in the four was made for cancer. Authors` Center examined previously 90% but recently 70% of the examinees. The remainder underwent the examination in other medical facilities. Tests are blood analysis, electrocardiography and computed radiography of chest with imaging plate, of which data have been accumulated either in photodisc or in host computer. From 1973 to 1993, the cardiovascular diseases increased from 6.1% to 26.9%, metabolic and endocrinic ones like diabetes, 3.6% to 19.7%, and bowel ones, 0.9% to 12.3%. Correlations of these diseases with A-bomb irradiation are not elucidated and possibly poor. Five classes of cancer examinations are performed but the examinee rate in the survivors is as low as 7.6-21.8% (1993). The cancer of the large intestine is increasing. The overall examinee rates in the survivors were 70.6% in 1965-1967, 69.5% in 1976-1977 and 58.2% in 1990. In conclusion, how to examine the survivors, who are getting older, as many as possible is the future problem. (H.O.)

    It has been 13 years since the operation of medical record data base for A-bomb survivors was started in the Scientific Data Center for Atomic Bomb Disaster at the Nagasaki University. This paper presents the basic data in handling the data base. The present data base consists of the following 6 items: (1) 'fundamental data' for approximately 120,000 A-bomb survivors having an A-bomb survivors' handbook who have been living in Nagasaki City; (2) 'Nagasaki Atomic Bomb Hospital's data', covering admission medical records in the ward of internal medicine; (3) 'pathological data', covering autopsy records in Nagasaki City; (4) 'household data reconstructed by the survey data'; (5) 'second generation A-bomb survivors data', including the results of mass screening since 1979, and (6) 'address data'. Based on the data, the number of A-bomb survivors, diagnosis records at the time of death, the number of A-bomb survivors' participants in health examination, tumor registration, records of admission to the internal ward in Nagasaki Atomic Bomb Hospital, autopsy records, and household records are tabulated in relation to annual changes, age at the time of A-bombing, distance from the hypocenter, or sex.

    In evaluable 456 (60 %) of 750 leukemic patients exposed at less than or equal to9,000 m from the hypocenter, diagnosis and subtypes of leukemia were reevaluated in relation to radiation doses and age at the time of bombing using a new classification method of French-American-British (FAB). The FAB classification diagnosed 63 patients (13.5 %) as acute lymphoid leukemia (ALL), 181 (39.0 %) as acute myeloid leukemia (AML), 26 (5.6 %) as myelodysplastic syndrome (MDS), 106 (22.8 %) as chronic myeloid leukemia (CML), 39 (7.5 %) as adult T-cell leukemia, and 5 (0.8 %) as chronic lymphocytic leukemia. According to radiation doses, the incidence of CML increased in the group exposed to one to 99 cGy; the incidences of ALL and MDS increased in the group exposed to greater than or equal to100 cGy. The incidence of CML was definitively higher in Hiroshima than Nagasaki in all groups; this was noted in the group exposed to 0 cGy (approximately 2.5 times higher). The incidences of ALL and MDS showed a tendency to increase in proportion to radiation doses. In the group exposed to greater than or equal to100 cGy, the incidences of ALL, CML, and MDS increased in patients younger than 15 years, those aged 16 - 35 years, and those older than 36 years, respectively, at the time of the bombing. In this group, there were also differences in latent period (10 yr in ALL and CML, 15 yr in AML, and 17 yr in MDS). None of the AML patients in the group exposed to greater than or equal to100 cGy had M3. (Namekawa, K.).

    The medical examination was carried out in Brazil, Paraguay, Bolivia, Argentina and Peru on 80, 4, 7, 11 and 3 survivors, respectively, from Oct. 30 to Nov. 15, 1996. They (43 males and 62 females) were 66.5 years old in average. The examination involved physical measurements, blood and urine analyses, electrocardiography, health questionnaire and consultation with blood pressure measurement. Results were as follows: Anamnesis; hypertension (51.4%), heart diseases (23.8%), cancer (21.0%), diabetes (19.0%), hemorrhoids (19.0%), stroke (18.1%), stomach ulcer (12.4%) and others: Present major disease; hypertension (23.8%), diabetes (6.7%), heart diseases (6.7%), cancer (6.7%) and others. Loss of vigor (63.8%), complete exhaustion or fatigue (63.8%), heat intolerance (60.0%), numbness or tingling (43.8%), failure of memory (42.9%) and many others were recognized as subjective symptoms. Blood pressure measurement gave hypertensive findings in 31.4%. Normal ECG was found in 67.7%. Cases judged to be necessary for further examinations or for treatment were in 46.7%. This examination was concluded to be continued. (K.H.)

    A pilot study was made, based on an interview survey, to improve mental hygiene in A-bomb survivors. The study consisted of General Health Questionnaire (GHQ) 12 items, Composite International Diagnostic Interview (CIDI), Social Disabilities Schedule (SDS), and General Health Questionnaire (GHQ) 30 items. A majority of the subjects were those aged in their fifties, sixties, and seventies. Eighty A-bomb survivors answered GHQ 12 items, consisting of 7, 17, and 41 who were exposed at <2.0 km, 2.0-2.9 km, and {>=}3.0 km from the hypocenter, respectively, and 15 who entered the city early after A-bombing. Thirty-three A-bomb survivors answered CIDI. According to the distance from the hypocenter, the corresponding figures were 2, 10, 15, and 6 A-bomb survivors. The survey for GHQ 12 items revealed that more A-bomb survivors exposed nearer the hypocenter suffered from mental problems. In the survey for CIDI, the most common complaints were found to be physical expression disorder (n=9) and chronic pain (n=8), followed by hypochondria (n=4), panic disorder (n=2), and anxiery (n=one). According to the SDS survey, 85% were judged as having no mental disorder, and the remaining 15% as having merely mild or moderate disorder. (N.K.).

    Micronucleus and Howell-Jolly (H-J) bodies in bone marrow and in peripheral blood were investigated for 31 a-bomb survivors, and 21 thorotrast injected patients with 7 controls. The rate of micronucleus in myeloerythroblast was 0.263% for a-bomb survivors and 0.288% for thorotrast patients, which were higher than the controls, 0.050%. Correlations of micronucleus appearance with the incidence of chromosome aberrations and with estimated exposure dose were observed, suggesting that the micronucleus appearance could be an indicator of radiation damage. Also the micronucleus appearance in routine examinations could suggest the presence of chromosome aberrations. In the case of thorotrast patients H-J bodies appeared in high rate.

    In January 1949, Norris Bradbury gave a lecture at the National War College which summarized the progress Los Alamos had made since the end of the war. The transcript of the talk was filed and forgotten until it surfaced fifty years later. It is, perhaps, one of the best summaries of the state of the United States nuclear weapons program in 1949. It is also evidence of how Bradbury saw the future of atomic weapons. It is presented in full, with minor editing, and begins as follows: Since the first use of an atomic bomb on August 5 [sic], 1945, over the city of Hiroshima, Japan, there has been a continual flood of speculation and discussion concerning the effect of this new weapon on military technology. Much of this speculation and discussion has been intelligent and fruitful; much, I regret to say, has had neither of these characteristics. The enormity of the device, in terms of potential destruction and loss of life, and the practical necessity to surround the technical facts with full security restrictions have only combined to make the problem more difficult. At the same time, it is imperative that policymaking personnel in charge of long range national planning know the basic facts concerning atomic weapons and have these facts in a reasonable perspective. This document describes these potentialities in detail.

    Myelodysplastic syndromes (MDSs) is a hematological neoplasm defined by ineffective hematopoiesis, dysplasia of hematopoietic cells, and risk of progression to acute leukemia. MDS occurs as de novo or secondary, and chemoradiotherapy for cancers is thought to increase the risk of MDS among patients. Recently, an epidemiological study for MDS among A-bomb survivors was performed, and it clearly demonstrated that the exposure to external radiation significantly increased the risk of MDS. Precise epidemiological data among survivors have revealed important clinical factors related to the risk of leukemias. In this review, by comparing data for secondary MDS and leukemia/MDS among survivors, several factors which would affect the risk of MDS, especially secondary MDS, are discussed.

    To clarify the factors and reasons for the differences in the outcomes of rescue and relief efforts in Hiroshima and Nagasaki, mainly focusing on the numbers of rescue/relief staffs and casualties in the period within 72 hours of the atomic bombings in August 1945. By retrieving the data and information from the records and reports concerning the disasters in the two cities, together with other publications as to the damages by the atomic bombings and subsequent rescue-relief activities, and restoration activities. It seems that there was less damage in Nagasaki, where a stronger atomic bomb was used than in Hiroshima. There were crucial geographic factors that led to the different effects in terms of the numbers of victims; however, systematic organization and mobilization of rescue and relief staffs, maintenance of functional transportation, and advanced medical knowledge and public warning with regard to disaster all may have contributed to a lower death toll and increase in survivors in Nagasaki.

    An outline of four survey reports right after the atomic bombing in Nagasaki and Hiroshima is introduced. The report of Manhattan District Atomic Bomb Investigating Groups: The subjects of this survey were 900 inpatients in Nagasaki (for 16 days from September 20) and Hiroshima (for 5 days from October 3). Two hundreds and forty-nine patients (16%) died. In cases died without injury, the severe symptoms were alopecia, purpura, hemorrhage, oral cavity and pharynx lesion, vomiting, diarrhea and fever. The residual radioactivity measured at six weeks later was 6-25 roentgen in Hiroshima and 30-110 roentgen in Nagasaki (Nishiyama riverhead area). These values were lower than the predicted value from the clinical consequence. The report of Joint Commission for the Investigation of the Atomic Bomb: Following the above survey, about 6500 subjects were investigated both in Nagasaki and Hiroshima. Incidence of alopecia was investigated by shielded situation at a spot of 2.1 to 2.5 km from a blast center. It was 7.2% of outdoors (shielded: 7.3%, non-shielded: 17.4%) and 2.9% of indoors. The report of the Special Committee for Atomic Bomb Casualty Investigation and Research of the Scientific Research Council of Japan: General part of the report consists of medical part and physical part, and reports from each university were classified and listed in the supplement. Survey of Nagasaki Medical College (not in public): About 8000 subjects were investigated from October to December. Data were gathered up about lethality, time of death, injury and radiation sickness, etc. There was also autograph of a relief squad of the Nagasaki Medical College. (K.H.)

    Einstein voiced his ethical views against war as well as fascism via venues and alliances with a variety of organizations still debated today. In 1939, he signed a letter to President Roosevelt (drafted by younger colleagues Szilard, Wigner and others) warning the U.S.government about the danger of Nazi Germany gaining control of uranium in the Belgian-controlled Congo in order to develop atomic weapons, based on the discovery of fission by Otto Hahn and Lise Meitner. In 1945, he became a member of the Princeton-based ``Emergency Committee for Atomic Scientists'' organized by Bethe, Condon, Bacher, Urey, Szilard and Weisskopf. Rare Einstein slides will illustrate Dr.Rife's presentation on Albert Einstein's philosophic and ethical convictions about peace, and public stance against war (1914-1950).

  13. Personality and Major Depression among Directly Exposed Survivors of the Oklahoma City Bombing

    Full Text Available Background. Few disaster studies have specifically examined personality and resilience in association with disaster exposure, posttraumatic stress disorder (PTSD, and major depression. Methods. 151 directly-exposed survivors of the Oklahoma City bombing randomly selected from a bombing survivor registry completed PTSD, major depression, and personality assessments using the Diagnostic Interview Schedule for DSM-IV and the Temperament and Character Inventory, respectively. Results. The most prevalent postdisaster psychiatric disorder was bombing-related PTSD (32%; major depression was second in prevalence (21%. Bombing-related PTSD was associated with the combination of low self-directedness and low cooperativeness and also with high self-transcendence and high harm avoidance in most configurations. Postdisaster major depression was significantly more prevalent among those with (56% than without (5% bombing-related PTSD (P<.001 and those with (72% than without (14% predisaster major depression (P<.001. Incident major depression was not associated with the combination of low self-directedness and low cooperativeness. Conclusions. Personality features can distinguish resilience to a specific life-threatening stressor from general indicators of well-being. Unlike bombing-related PTSD, major depression was not a robust marker of low resilience. Development and validation of measures of resilience should utilize well-defined diagnoses whenever possible, rather than relying on nonspecific measures of psychological distress.

    The U.S. Government's official narrative denies the effects of residual radiation which appeared one minute after the atomic bomb detonations in Hiroshima and Nagasaki. This paper explores declassified documents from the U.S. Atomic Energy Commission, the Atomic Bomb Casualties Commission, and others and shows that these documents actually suggested the existence of serious effects from residual radiation.

    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 too small to be found by routine methods or that the methods used were not suitable.

  17. Radiation effect on non-cancer diseases among a-bomb survivors

    It has been well documented in the literature that radiation induces DNA damages and increases cancer risk. Besides cancer risk, the Life Span Study (LSS) on A-bomb survivors in Hiroshima and Nagasaki that has been conducted since 1950 by RERF demonstrated an increase in non-cancer death by cardiovascular diseases and chronic liver diseases (1). Since LSS analysis depends on death certificate, a physiological mechanism has not been elucidated how radiation increases the incidence of non-cancer diseases. In order to elucidate radiation effect on non-fatal disorders, RERF has conducted the Adult Health Study (AHS) since 1958 where 23,000 A-bomb survivors have been examined every other year. This study suggested that radiation exposure about 55 years before reduced the immune response to pathogens such as HB virus and Chlamydia pneumoniae, increased the levels of serum inflammatory markers, the prevalence of chronic hepatitis/liver cirrhosis and senile cataract, and the incidence of cardiovascular diseases. Our colleagues reported a dose-dependent decrease in the CD4 T cell number among A-bomb survivors (2,3). Since chronic inflammation and oxidative stress are causative of atherogenic cardiovascular diseases or cataract, we speculate a decrease in the immune response to pathogens, at least in part, is one of the mechanisms that A-bomb exposure increased non-cancer diseases. When the levels of inflammatory marker, C-reactive protein (CRP), were analyzed among subjects with evidence of Chlamydia pneumoniae infection, significantly higher levels of CRP were associated with antibodies to Chlamydia pneumoniae in those subjects receiving >1Gy than those receiving <5mGy. It is well known that high CRP is one of the risk factors of arteriosclerosis (4,5). Thus, A-bomb exposure seems to augment inflammatory response to pathogens, though of which mechanisms are not clear now.

    Excess risk of female breast cancer is among the most comprehensively documented late effects of exposure to substantial doses of ionizing radiation, based on studies of medically irradiated populations and the survivors of the A-bombings of Hiroshima and Nagasaki. This study looks at the interaction of dose with epidemiological factors like age at first full-term pregnancy and family history of breast cancer, most closely associated with risk in epidemiological studies of non-irradiatied populations. 1 fig., 2 tabs.

    Four decades after the actual events, quantitative characterization of the radiation fields at Hiroshima and Nagasaki continues to be sought, with high accuracy a goal justified by the unique contribution to radiation protection standards that is represented by the medical records of exposed survivors. The most recent effort is distinguished by its reliance on computer modeling and concomitant detail, and by its decentralized direction, both internationally and internally to the US and Japan, with resultant ongoing peer review and wide scope of inquiry. A new system for individual dose estimation has been agreed upon, and its scientific basis has been elaborated in the literature as well as in a comprehensive treatise to be published in the Spring of 1987. In perspective, this new system appears to be an unusually successful achievement that offers the expectation of reliable estimates with the desired accuracy. Some aspects leading to this expectation, along with a caveat, are discussed here. 4 refs., 8 figs., 3 tabs.

    There is a need for accurate dosimetry for studies of health effects in the Japanese atomic bomb survivors because of the important role that these studies play in worldwide radiation protection standards. International experts have developed dosimetry systems, such as the Dosimetry System 2002 (DS02), which assess the initial radiation exposure to gamma rays and neutrons but only briefly consider the possibility of some minimal contribution to the total body dose by residual radiation exposure. In recognition of the need for an up-to-date review of the topic of residual radiation exposure in Hiroshima and Nagasaki, recently reported studies were reviewed at a technical session at the 57th Annual Meeting of the Health Physics Society in Sacramento, California, 22-26 July 2012. A one-day workshop was also held to provide time for detailed discussion of these newer studies and to evaluate their potential use in clarifying the residual radiation exposures to the atomic-bomb survivors at Hiroshima and Nagasaki. Suggestions for possible future studies are also included in this workshop report.

    The role of the psychiatric advanced practice nurse in promoting psychological health and resiliency for patients, their families and staff following the Boston Marathon bombings is reviewed. On April 15, 2013, 2 bombs exploded near the finish line at the Boston Marathon. Within minutes, 39 patients suffering from multiple injuries presented at a level I trauma center. The magnitude of this event and its effect on our hospital required a comprehensive response that would promote resiliency and healing. Lessons shared from responders to other tragedies were helpful in guiding our interprofessional efforts. The multiple layers of our response are reviewed to offer learnings that may inform others as they work to promote resiliency and healing following traumatic events. In response to this event, we utilized a trauma-informed care framework emphasizing physical, psychological, and emotional safety to assist staff, survivors, and families on their journey of healing. Emotional reactions were dramatic but were eased by the psychological care and education that our patients, their families, and staff received in the first days to weeks after the bombings. The psychiatric advanced practice nurse can influence positive outcomes by utilizing a trauma-informed care framework.

    To examine terrorism survivors' perceptions of factors likely to promote coping and recovery, and to determine whether coping supports vary according to demographic, physical and mental health, incident-exposure and bereavement variables. Individuals directly exposed to and/or bereaved by the 2002 Bali bombings and who had participated in a New South Wales Health therapeutic support program completed cross-sectional telephone interviews during July-November 2010. Spoken passages were categorised into coping support themes. Advocated supports were then examined by demographic, physical and mental health, incident-exposure and bereavement variables. Based on their experiences, respondents identified personal, social and service-related factors that they believed would optimally support future survivors of terrorism. Of the 81 people contacted, 55 (68%) participated, providing a total of 114 comments. Thirty-two respondents were women, and 54 had lost relatives or friends in the bombing. Mean age was 50 years (range, 20-73 years). Four meaningful coping support themes emerged, with excellent inter-rater reliability: professional help and counselling; social support; proactive government response and policy; and personal coping strategies. Women were significantly more likely to advocate the need for proactive government response (P = 0.03). Men were more likely to endorse the use of personal coping strategies (P terrorism-affected groups. Male survivors may benefit more from mental health interventions that initially build on problem-focused forms of coping, including brief education about reactions and periodic check-ups. Proactive government health and support services that allow simplified and longer-term access were consistently identified as priority areas.

    1991-01-01

    The cinema and the atomic bomb are two of the most significant technological innovations of the past-century - their influence on culture has provoked tremendous political, academic, and popular debate. The point at which these two technologies intersect is what the author calls Atomic Bomb Cinema.' Since 1945 almost six hundred films with images of nuclear weapons have been released in the US, and they have been virtually ignored by everyone but the film going public. This study shows how Bomb films' use recurring themes and formal structures, and therefore must be treated as a coherent body of films; identifies historical, mythological, and contemporary motifs; and analyzes these films from two points of view: interdisciplinary (history, politics, economics, sociology, and aesthetics) and cross-cultural (American, Japanese, British, and Australian). The most important element of Atomic Bomb Cinema is the Apocalyptic Imagination; film makers use it to structure their narratives and explore a wide range of ideological issues. In contrast to commonly held beliefs, Atomic Bomb Cinema is undeniably part of a process that helps people to understand the threat of nuclear war. In this instance, the cinema is one cultural institution that contributes to a healthy society.

    Up to now the historical explanation for the fact that NS Germany did not develop an atomic bomb was that there was enough scientific and technical knowledge but not enough resources. Recent historical research showed that the German scientists in the ''Uranverein'' did not know the cross section of U-235 and had no possibility to measure these cross sections. There exist only very few documents dealing with the bomb. The bomb was treated as a special case of a reactor. Obviously the German scientists did not know he bomb technology. It seems that the project was not success-oriented because the scientists expected to be sent to the front in case of a project stop.

    This is a report of the results of a study of biochemical mutations in children of A-bomb survivors. An electrophoretic examination of a series of 30 proteins, undertaken in 13,052 children in the exposed group and 10,609 children in the non-exposed control group, yielded three mutations in each group. These mutations altered the electrophoretic mobility for glutamic pyruvic transaminase, phosphoglucomutase-2, and nucleosidephospholilase in the exposed group; and for haptoglobin, adenosinedeaminase, and 6-phosphogluconate dehydrogenase in the control group. An examination of enzyme activity for 4,989 children in the exposed group yielded one mutation for triose phosphate isomerase; no mutations were encountered in any of the 5,026 children in the control group. Summarizing the results of the two series, the mutation rates observed in the exposed and control groups are thus 0.60 x 10/sup -5/ and 0.64 x 10/sup -5/, respectively, per locus per generation, with 95 % confidence limits of 0.2 - 1.5 x 10/sup -5/ and 0.1 - 1.9 x 10/sup -5/, respectively.

    This work gives a fresh look at the major discoveries leading to nuclear fission within the historical perspective. The focus is on the main contributors to the discoveries in nuclear physics, leading to the idea of fission and its application to the creation of the atomic bombs used at the end of the World War II. The present work is a more complete review on the history of the nuclear physics discoveries and their application to the atomic bomb. In addition to the traditional approach to the topic, focusing mainly on the fundamental physics discoveries in Europe and on the Manhattan Project in the United States, the nuclear research in Japan is also emphasized. Along with that, a review of the existing credible scholar publications, providing evidence for possible atomic bomb research in Japan, is provided. Proper credit is given to the women physicists, whose contributions had not always been recognized. Considering the historical and political situation at the time of the scientific discoveries, thought-provoking questions about decision-making, morality, and responsibility are also addressed. The work refers to the contributions of over 20 Nobel Prize winners. EM-A is grateful to Prof. Walter Grunden and to Prof. Emeritus Shadahiko Kano, Prof. Emeritus Monitori Hoshi for sharing their own notes, documents, and references, and to CCCU for sponsoring her participation in the 2013 Nuclear Weapons Seminar in Japan.

    In 1985, 40 years after the bombing, 37 (8 %) of a total of 814 A-bomb survivors living in Tokyo visited the Department of Neuro-Psychiatry. This is an analysis of these A-bomb survivors suffering from mental disorders. There were 11 men and 26 women. They ranged in age from 45 to 87 years with a median of 61. Eighteen survivors (55 %) were exposed within 2,000 m from ground zero, and 21 (66 %) presented with acute radiation symptoms. According to the classification of DSM-III, features of mental disorders fell into five types: (1) organic psychotic conditions (n = 7), (2) endogenous psychotic conditions (n = 14), (3) delution (n = 3), (4) anxiety somatization (n = 11), and (5) personality disorder (n = 2). Psychotic conditions characterized by mixed atypical symptoms, variable clinical features during the process, and undefined somatic symptoms were noticeable in this series. This is in contrast to the previous reports dealing with neurasthenic A-bomb survivors. The etiology of psychotic conditions must await further study. (Namekawa, K.).

    Since August 1991, six surveys have been made on thyroid cancer in children in Ukraine and Belorussia. The results were compared with those for Hiroshima A-bomb survivors. Children with thyroid cancer were characterized as having the following: (1) frequent occurrence of thyroid cancer; (2) extremely short latency period; (3) poorly differentiated papillary adenocarcinoma; (4) frequent occurrence within the thyroid gland; (5) the association of fibrosis, lymphocyte infiltration, and proliferation of follicular epithelial cells; (6) frequent occurrence of sclerosing variant of papillary cancer associated with fibrosis and lymphocyte infiltration, especially in heavily exposed areas. These findings were supposed to be attributable to Chernobyl nuclear power plant accident. No data has been available on infantile thyroid cancer in Hiroshima A-bomb survivors because of the following reasons: (1) acute death from acute radiation injury, leukemia and cancer other than thyroid cancer; (2) few survey on thyroid cancer during the first 10 years after exposure; (3) the lack of surgical data on thyroid cancer. In the case of Chernobyl survivors, there were few acute death cases; I-131 seemed to have damaged specifically the thyroid gland; heavily exposed areas corresponded to areas with low iodine intake; pediatric thyroid gland is sensitive to I-131, leading to the possibility that infantile thyroid cancer may have been induced by I-131.

    It was no accident that the Holocaust and the Atomic Bomb happened at the same time. When the Nazis came into power in 1933, their initial objective was not to get rid of Jews. Rather, their aim was to refine German culture: Jewish professors and teachers at fine universities were sacked. Atomic science had attracted a lot of Jewish talent, and as Albert Einstein and other quantum exiles scattered, they realized that they held the key to a weapon of unimaginable power. Convincedthat their gentile counterparts in Germany had come to the same conclusion, and having witnessed what the Nazis were

    A 43 years old housewife with a history of exposure to an atomic bomb at 8 years old, recently developed anemia and palpitation. The laboratory data showed accelerated ESR, anemia (Hb 10.0 g/dl), and hyper ..gamma..-globulinemia. Despite the suspicion of late effect of atomic radiation, further examinations confirmed the diagnosis of left atrial myxoma. The echocardiographic studies revealed the decrease of diastolic descent rate, and multiple echos reflected from the tumor within the mitral orifice during diastole. Cardiac catheterization demonstrated remarkably high value of PCWP (V-wave 38 mmHg) and space filling defect moving from left atrium to left ventricle by cineangiography. Phonecardiographic studies were similar to mitral stenosis. After left atrial myxoma was removed, her symptoms and laboratory data including all noninvasive findings were improved. Therefore we suspected that her symptoms was related with left atrial myxoma rather than the late effect of atomic bomb exposure. We have discussed its significance and usefulness of noninvasive diagnostic approaches as well as whole body computed tomography in heart tumor.

    According to official accounts, the U.S. knew nothing about Nazi Germany's efforts to get an atomic bomb until the end of the World War II, but had feared the worst. As it turned out, the Germans had made little progress. But did someone in the Allied camp know in 1942? In his 1986 book, The Griffin, Arnold Kramish relates how Paul Rosbaud, a spy for MI6, the British secret intelligence service, kept his handlers informed during the War about the German atomic project and reported the decision to give up on a bomb. Kramish's revelations are, understandably, thinly documented and Rosbaud's name can hardly be found independenly anywhere else. But as Samuel Goudsmit's papers in the Bohr Library show, he knew and communicated with Rosbaud from August 1945 on. In 1986, 15 letters exchanged by Goudsmit and Rosbaud were removed by the Government from the Library and eventually placed in the National Archives under classification review. Renewed interest in the Rosbaud story was engendered last year when his family sued MI6 in an English court for the release of the Rosbaud file. So far the spy agency has refused to reveal even that there is such a file. Discovering authoritatively what Rosbaud told the British and what they did with the information is clearly of historical interest.

    The booklet describes the history of the ``bomb`` from the ``Manhattan project`` to the present, tracing the drastic changes provoked by the nuclear weapons for world politics, but also for ethical thought and cultural conception of ourselves. Both the crises at the brink of nuclear war - Suez crisis, Berlin crisis, Cuba crisis - and the development of strategic doctrines, the arms race, the history of arms control, and the anti-atomic movement are dealt with in the contributions written by renowned authorities. The concluding paper on the role of nuclear weapons in a world politics that has become more intricate shows insistently that the age of the bomb is anything but over since the end of the East-West conflict. The example of North Korea or of the ``plutonium transfer deals`` from nuclear installations of the Soviet Union has recently shown that also the future will remain ``atomic``. (orig./HP) [Deutsch] Das Buch schildert die Geschichte der `Bombe` vom `Manhattan-Projekt` bis in die Gegenwart, und es zeichnet die einschneidenden Veraenderungen nach, die die Kernwaffe fuer die Weltpolitik, aber auch fuer das ethische Denken und unser kulturelles Selbstverstaendnis heraufbeschworen haben. Die Krisen am nuklearen Abgrund - Suez-Krise, Berlin-Krise, Kuba-Krise - werden in den von ausgewiesenen Sachkennern geschriebenen Beitraegen ebenso behandelt wie die Entwicklung der strategischen Doktrinen, der Ruestungswettlauf, die Geschichte der Ruestungskontrolle und die Anti-Atombewegung. Dass das Zeitalter der Bombe mit dem Ende des Ost-West-Konflikts keineswegs vorueber ist, zeigt eindringlich der abschliessende Beitrag ueber die Rolle der Kernwaffen in einer unuebersichtlicher gewordenen Weltpolitik. Das Beispiel Nord-Korea oder die `Plutonium-Transfergeschaefte` aus den Atomanlagen der ehemaligen Sowjetunion haben in juengster Zeit gezeigt, dass auch die Zukunft `atomar` bleiben wird.

    On April 15, 2013, Boston residents and guests gathered for the Boston Marathon. Two explosives at the finish line killed three people and injured hundreds of others. As part of our clinical encounters, patients of the Boston Center for Refugee Health & Human Rights were asked about the marathon bombing. We were concerned about the high level of armed security as many of our patients had been detained in their countries of origin. Eighty patients seen between April 16 and July 7, 2013 were asked about their experience of the Boston Marathon bombing and its aftermath. A retrospective chart review was undertaken and data analyzed using Atlas.ti & SPSS. Approximately 86 % of those interviewed were reminded of their past trauma. The following themes emerged: triggering and trauma related symptoms, content specific cognitive schemas, recognition of the universality of violence, fears of discrimination, issues surrounding safety, and specific concerns of Muslims.

    The centrality of atomic bombings of Hiroshima and Nagasaki in Japanese collective memory has been often perceived by the country's neighbours, i.e. the People's Republic of China and South Korea, as a pillar of the country's (alleged) "victim consciousness" and amnesia in regard to the suffering inflicted on others. For this reason, the…

    Serum ferritin was determined in A-bomb survivors, and its significance was evaluated. A low-ferritin group included many of the females under the age of 50, who mostly had iron deficient anemia. A high-ferritin group included many older-aged A-bomb survivors who had secondary anemia due to hemochromatosis, paroxismal nocturnal hemoglobinuria (PNH), and multiple myeloma. Secondary anemia due to hemochromatosis, PNH, leukemia, and sideroblastic anemia was detected in those who were old and had underlying moderate or severe anemia with a high ferritin level. As the results of this investigation, blood examination combined with serum ferritin determination is valuable for diagnosis of anemia and detection of underlying diseases.

  20. Was Nazi Germany on the Road to an Atomic Bomb after all?

    2006-04-01

    The story of Germany's efforts to develop a nuclear weapon during World War II is a much written about and contentious subject. However there has been agreement on one thing: by the end of the War the Germans had not achieved and were nowhere near to building a bomb. The dispute therefore has been about why Germany did not succeed. Now, from Germany, comes a challenge to this truth, in the provocative book Hitlers Bombe by Rainer Karlsch. The bombshell in Hitler's Bombe is the assertion that German scientists developed and tested a primitive fission and fusion nuclear weapon in March 1945. Karlsch bases this claim on testimony of witnesses in 1962, previously secret Russian documents, and the results of soil tests carried out in 2004 and 2005. However the physics is very murky and it seems out of the question that Germany had enough Uranium 235 or produced any Plutonium for a bomb. Hitlers Bombe also makes other, better documented and more credible revisionist assertions. These include the claim that the Nazis did continue to try to build a bomb after 1942 and that not Werner Heisenberg, but Kurt Diebner and Walther Gerlach were then the leaders of the German Uranium project. Karlsch's book therefore deserves more attention from physicists and historians than it has received in the United States.

    The concordance rate for diagnoses of atomic bomb-related cases of leukemia in Nagasaki was determined using the French-American-British (FAB) classification for acute leukemias and myelodysplastic syndromes (MDS). Two Radiation Effects Research Foundation (RERF) hematologists and one of the members (JMB) of the FAB cooperative group reviewed independently the peripheral blood and/or bone marrow smears from 193 people with leukemia or a related disorder. There was 85 % agreement in the identification of types and subtypes of acute leukemia. There was almost complete agreement for the diagnoses of non-FAB disorders (chronic myeloid leukemia (CML), adult T-cell leukemia (ATL) and others) resulting in overall concordance of 88.2 %. The present study suggest that the previously established leukemia types for about a quarter of the cases of acute leukemia and related disorders except CML should be changed. Considerable numbers of cases of ATL and MDS were involved in this series. The frequency of the former disease was not high in the high-dose irradiated group, but that of the latter was considerably high. All subtypes of AML except M3 and M6 were present in the high-dose group. The striking difference in CML incidence between Nagasaki and Hiroshima may continue to be a problem in relation to biological response to radiation exposure.

    To compare the radiation-associated relative risks of cancer incidence and mortality in groups exposed to ionizing radiation in the course of treatment for a variety of malignant and non-malignant conditions with those in the Japanese A-bomb survivor cancer incidence and mortality data. Comparison of the excess relative risk coefficients derived from published information for each study with the excess relative risk coefficient in comparable (age at exposure, time since exposure, sex) matched subsets of the Japanese A-bomb survivor cancer incidence and mortality data. Sixty-five studies of persons who have received appreciable doses of ionizing radiation in the course of treatment and for whom there is adequate ascertainment of cancer incidence or mortality are identified, from which 116 cancer-site-specific estimates of excess relative risk are derived. Relative risks tend to be lower in the medical series than in the Japanese A-bomb survivors. The most marked discrepancies between the relative risks in the medical series and in the A-bomb survivors are for leukaemia, where 12 of the 17 medical studies have significantly lower relative risks than those observed in the Japanese data. However, the ratio between the relative risks in the medical studies and in the Japanese data tends to diminish with increasing average or maximal therapy dose. This is observed for all cancer sites and is particularly marked for leukaemia. After taking account of cell sterilization and dose fractionation the apparent differences between the relative risks for leukaemia in the Japanese A-bomb survivors and in the medical series largely disappear. This suggests that cell sterilization largely accounts for the discrepancy between the relative risks in the Japanese data and the medical studies. Other factors, such as the differences in underlying cancer risks between the Japanese A-bomb survivors and the medical series, and dose-fractionation effects, may also contribute. The relative

    To assess the impact of a structured intervention, the "primary intervention for memory structuring and meaning acquisition" (PIMSMA) performed randomly in the emergency department with survivors of suicide bombing attacks, on their medium-term mental health outcome. Follow up and assessment 3-9 months postinjury, and 24 months thereafter. A tertiary referral general hospital in Tel Aviv, Israel. Injured survivors of 9 suicide bombing and suicide shooting, men and women aged 16-72 at the time of the incident. Diagnosis of posttraumatic stress disorder (PTSD) was made using the Hebrew validated version of the DSM-IV SCID-PTSD rating scale. Other psychiatric symptoms were assessed using the following rating scales: impact of event scale (IES), Hamilton rating scale for depression (HAM-D) and for anxiety (HAM-A), and the Pittsburgh sleep quality index (PSQI). Effects of PIMSMA and PTSD level of psychological distress were analyzed using ANOVA and for change over time for continuous variables repeated measured multivariate analyses was performed, and for categorical variables nonparametric-related sample McNemar. Logistic regression for variable associated with PTSD was performed. Out of 213 eligible injured survivors evacuated to our ER, 129 were retrieved 3-9 months after the incident, and 53 were available for assessment 2 years later. Multivariate analyses for being PTSD vs non-PTSD at the first evaluation, being hospitalized OR = 5.6 (95 percent CI 1.1-27.6) and treated OR = 24.5 (95 percent CI 2.8-200) were the only predictors, with no effect (p = 0.9) for PIMSMA vs other supportive intervention. Predictor for PTSD at the second evaluation were IES severity score at first evaluation OR = 1.1 (95 percent CI 1.04-1.2). The PIMSMA approach is as good as the nonspecific supportive treatment performed routinely in the ED with all survivors of traumatic events of any origin. Further studies are needed to establish valid, evidence-based treatment approaches for the

    An accumulation of disaster mental health research literature in the last few decades has contributed knowledge to direct disaster mental health interventions. However, no single set of principles can necessarily outline all anticipated mental health needs to be encountered in a particular disaster. To illustrate how different disaster scenarios may yield a divergence of mental health needs, this article compares mental health findings from two distinctly different studies of two very different populations affected by two very different disasters: directly exposed survivors the Oklahoma City bombing and sheltered evacuees from Hurricane Katrina. Research on the two disasters reviewed illustrates many facets and complexities of postdisaster mental health needs in different populations in different settings after different types of disasters. The major findings of the Oklahoma City bombing study related to posttraumatic stress disorder and the main findings of the Hurricane Katrina study involved need for treatment of preexisting chronic mental health and substance abuse problems. The disaster studies in this review diverged in type of disaster, affected populations, setting, and timing of the study, and these studies yielded a divergence of findings. One disaster mental health model clearly cannot adequately describe all postdisaster scenarios.

    Full Text Available Abstract Background Analyses of Japanese A-bomb survivors' cancer mortality risks are used to establish recommended annual dose limits, currently set at 1 mSv (public and 20 mSv (occupational. Do radiation doses below 20 mSv have significant impact on cancer mortality in Japanese A-bomb survivors, and is the dose-response linear? Methods I analyse stomach, liver, lung, colon, uterus, and all-solid cancer mortality in the 0 – 20 mSv colon dose subcohort of the 1950–90 (grouped mortality cohort, by Poisson regression using a time-lagged colon dose to detect latency, while controlling for gender, attained age, and age-at-exposure. I compare linear and non-linear models, including one adapted from the cellular bystander effect for α particles. Results With a lagged linear model, Excess Relative Risk (ERR for the liver and all-solid cancers is significantly positive and several orders of magnitude above extrapolations from the Life Span Study Report 12 analysis of the full cohort. Non-linear models are strongly superior to the linear model for the stomach (latency 11.89 years, liver (36.90, lung (13.60 and all-solid (43.86 in fitting the 0 – 20 mSv data and show significant positive ERR at 0.25 mSv and 10 mSv lagged dose. The slope of the dose-response near zero is several orders of magnitude above the slope at high doses. Conclusion The standard linear model applied to the full 1950–90 cohort greatly underestimates the risks at low doses, which are significant when the 0 – 20 mSv subcohort is modelled with latency. Non-linear models give a much better fit and are compatible with a bystander effect.

    The book is an expanded autobiography of the famous theoretical physicist Isaak Khalatnikov. He worked together with L.D. Landau at the Institute for Physical Problems lead by P.L. Kapitza. He is the co-author of L.D. Landau in a number of important works. They worked together in the frame of the so-called Nuclear Bomb Project. After the death of L.D. Landau, I.M. Khalatnikov initiated the establishment of the Institute for Theoretical Physics, named in honour of L.D. Landau, within the USSR Academy of Sciences. He headed this institute from the beginning as its Director. The institute inherited almost all traditions of the Landau scientific school and played a prominent role in the development of theoretical physics. So, this is a story about how the institute was created, how it worked, and about the life of the physicists in the "golden age" of the Soviet science. A separate chapter is devoted to today´s life of the institute and the young generation of physicists working now in science. It is an historic...

    Full Text Available The ROSE survey explores which science topics 15-year-old students want to study. By carrying out a factor analysis on results from Sweden it was possible to describe ten interest profiles. The interest profile with the strongest connection to the students’ interest in school science consists of topics such as explosive chemicals, ABC weapons, electric shocks, atoms and molecules. Only a minority of the students has these interests, but it is this minority who appreciates school science and who chooses to study science at upper secondary school. The factor analysis also reveals large differences between genders and furthermore, that the students’ own interests govern their choice of study programme at upper secondary school.

    The Atomic Papers annotates over 800 books published since 1945 and approximately 300 periodical articles since 1980 on every facet of the nuclear dilemma: the development and effects of the bomb, the arms race, nuclear proliferation, and the peace movement. Work on both sides of the nuclear power controversy also receives substantial attention. All references are to English-language material, and nearly half are to work published since 1980. The concluding chapter, ''The Art of Fission,'' describes over one hundred novels and stories with nuclear themes published since 1945--and, in a few cases, before that date.

    The study was performed to see whether the exposure to the atomic-bomb radiation gave any influence on the T cell functions. The function of peripheral T cells was analyzed by the limiting dilution analysis in 159 highly exposed subjects (63 males and 96 females; 43-86 years old) whose exposure dose due to the atomic-bomb radiation had been estimated to exceed 1.5 Gy. The control was 251 subjects (102 males and 149 females; the same range of age as above) exposed at a long distance (<0.005 Gy). Subjects were those who visiting the authors` facility for the purpose of health examination and giving the consent. There was any significant difference neither between frequencies of T cells responsible to PHA for proliferation nor between those of CD4 T cells responsible to Con A. In highly exposed subjects, an increase of CD4 T cells incapable of producing IL-2 by Con A stimulation was detected, which suggested a shift of helper T cell to Th-2 cell. (K.H.)

    A recent analysis of leukaemia mortality in Japanese A-bomb survivors has applied descriptive models, collected together from previous studies, to derive a joint excess relative risk estimate (ERR) by multi-model inference (MMI) (Walsh and Kaiser in Radiat Environ Biophys 50:21-35, 2011). The models use a linear-quadratic dose response with differing dose effect modifiers. In the present study, a set of more than 40 models has been submitted to a rigorous statistical selection procedure which fosters the parsimonious deployment of model parameters based on pairwise likelihood ratio tests. Nested models were consequently excluded from risk assessment. The set comprises models of the excess absolute risk (EAR) and two types of non-standard ERR models with sigmoidal responses or two line spline functions with a changing slope at a break point. Due to clearly higher values of the Akaike Information Criterion, none of the EAR models has been selected, but two non-standard ERR models qualified for MMI. The preferred ERR model applies a purely quadratic dose response which is slightly damped by an exponential factor at high doses and modified by a power function for attained age. Compared to the previous analysis, the present study reports similar point estimates and confidence intervals (CI) of the ERR from MMI for doses between 0.5 and 2.5 Sv. However, at lower doses, the point estimates are markedly reduced by factors between two and five, although the reduction was not statistically significant. The 2.5 % percentiles of the ERR from the preferred quadratic-exponential model did not fall below zero risk in exposure scenarios for children, adolescents and adults at very low doses down to 10 mSv. Yet, MMI produced risk estimates with a positive 2.5 % percentile only above doses of some 300 mSv. Compared to CI from a single model of choice, CI from MMI are broadened in cohort strata with low statistical power by a combination of risk extrapolations from several models

    Ever since the discovery of the mutagenic properties of ionizing radiation, the possibility of birth sex odds shifts in exposed human populations was considered in the scientific community. Positive evidence, however weak, was obtained after the atomic bombing of Japan. We previously investigated trends in the sex odds before and after the Chernobyl Nuclear Power Plant accident. In a pilot study, combined data from the Czech Republic, Denmark, Finland, Germany, Hungary, Norway, Poland, and Sweden between 1982 and 1992 showed a downward trend in the sex odds and a significant jump in 1987, the year immediately after Chernobyl. Moreover, a significant positive association of the sex odds between 1986 and 1991 with Chernobyl fallout at the district level in Germany was observed. Both of these findings, temporality (effect after exposure) and dose response association, yield evidence of causality. The primary aim of this study was to investigate longer time periods (1950-2007) in all of Europe and in the USA with emphasis on the global atmospheric atomic bomb test fallout and on the Chernobyl accident. To obtain further evidence, we also analyze sex odds data near nuclear facilities in Germany and Switzerland. DATA AND STATISTICAL METHODS: National gender-specific annual live births data for 39 European countries from 1975 to 2007 were compiled using the pertinent internet data bases provided by the World Health Organization, United Nations, Council of Europe, and EUROSTAT. For a synoptic re-analysis of the period 1950 to 1990, published data from the USA and from a predominantly western and less Chernobyl-exposed part of Europe were studied additionally. To assess spatial, temporal, as well as spatial-temporal trends in the sex odds and to investigate possible changes in those trends after the atomic bomb tests, after Chernobyl, and in the vicinity of nuclear facilities, we applied ordinary linear logistic regression. Region-specific and eventually changing spatial

    Epidemiological study was conducted on 151 cases (67 exposed and 84 nonexposed) of ovarian cancer registered at the Nagasaki Tumor Registry from 1973 to 1982, with emphasis on the relation to radiation exposure. Although the crude incidence rate of ovarian cancer in the exposed group was higher than in the nonexposed group, the age-adjusted relative risk was not significantly different. The relative risk of ovarian cancer incidence by age at the time of the A-bomb was high in the 10-19 group (puberty), and was low in the 40-49 group. It suggested the possibility that radiation carcinogenesis in the ovary was closely related to the secondary excess of gonadotrophic hormones following radiation injury of the ovary. No significant different in histological type between the exposed and nonexposed groups could be found.

  16. 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.

    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.

    The explosion of atom bombs over the cities of Hiroshima and Nagasaki in August 1945 resulted in very high casualties, both immediate and delayed but also left a large number of survivors who had been exposed to radiation, at levels that could be fairly precisely ascertained. Extensive follow-up of a large cohort of survivors (120,000) and of their offspring (77,000) was initiated in 1947 and continues to this day.

    Purpose: Phenomenological risk models for radiation-induced cancer are frequently applied to estimate the risk of radiation-induced cancers at radiotherapy doses. Such models often include the effect modification, of the main risk to radiation dose response, by age at exposure and attained age. The aim of this paper is to compare the patterns in risk effect modification by age, between models obtained from the Japanese atomic-bomb (A-bomb) survivor data and models for cancer risks previously reported for radiotherapy patients. Patterns in risk effect modification by age from the epidemiological studies of radiotherapy patients were also used to refine and extend the risk effect modification by age obtained from the A-bomb survivor data, so that more universal models can be presented here. Methods: Simple log-linear and power functions of age for the risk effect modification applied in models of the A-bomb survivor data are compared to risks from epidemiological studies of second cancers after radiotherapy. These functions of age were also refined and fitted to radiotherapy risks. The resulting age models provide a refined and extended functional dependence of risk with age at exposure and attained age especially beyond 40 and 65 yr, respectively, and provide a better representation than the currently available simple age functions. Results: It was found that the A-bomb models predict risk similarly to the outcomes of testicular cancer survivors. The survivors of Hodgkin’s disease show steeper variations of risk with both age at exposure and attained age. The extended models predict solid cancer risk increase as a function of age at exposure beyond 40 yr and the risk decrease as a function of attained age beyond 65 yr better than the simple models. Conclusions: The standard functions for risk effect modification by age, based on the A-bomb survivor data, predict second cancer risk in radiotherapy patients for ages at exposure prior to 40 yr and attained ages

  2. The influence of follow-up on DS02 low-dose ranges with a significant excess relative risk of all solid cancer in the Japanese A-bomb survivors

    Determinations of the lowest colon dose, D{sub min}, below which there is a statistically significant excess relative risk of all solid cancer, when analyses are restricted to the range [0, D{sub min}], are of current interest in research related to radiation protection and risk assessment. In reviewing recent cancer mortality reports on the Life Span Study (LSS) of Japanese A-bomb survivors, reported D{sub min} values were found to vary between different reports. The report 12 (follow-up: 1950-1990) found a D{sub min} of 50 mGy, but the most recent report 14 (follow-up: 1950-2003) found a D{sub min} of 200 mGy. There were small dosimetry changes between report 12, which used DS86, and report 14, which used DS02, but these changes are unlikely to account for a difference in D{sub min} of a factor of 4. This short communication examines the reasons for this difference in D{sub min} by presenting further investigations into D{sub min} using different trial values for D{sub min} and various follow-up time spans, all with the same DS02 dosimetry. Magnitudes of the low-dose risks in different dose ranges are also presented. It is shown here that the main influence on D{sub min} comes from the length of follow-up and a D{sub min} of 50 mGy may also be obtained with the most recent LSS mortality data and DS02, if a restricted follow-up is analyzed. A systematic trend was evident of lower D{sub min} values for earlier mortality follow-up periods, consistent with information from earlier LSS reports. Although it may seem surprising that the D{sub min} increases with longer follow-up and better statistics, this systematic trend appears to be a consequence of decreasing mortality risks with longer follow-up, even though the error bars on the risks are getting smaller with increasing follow-up. These systematic trends also persisted after accounting for differences between baseline cancer rates for two groups of survivors who were either proximal or distal to the A-bomb

  3. Neutron relative biological effectiveness for solid cancer incidence in the Japanese A-bomb survivors: an analysis considering the degree of independent effects from γ-ray and neutron absorbed doses with hierarchical partitioning.

    It has generally been assumed that the neutron and γ-ray absorbed doses in the data from the life span study (LSS) of the Japanese A-bomb survivors are too highly correlated for an independent separation of the all solid cancer risks due to neutrons and due to γ-rays. However, with the release of the most recent data for all solid cancer incidence and the increased statistical power over previous datasets, it is instructive to consider alternatives to the usual approaches. Simple excess relative risk (ERR) models for radiation-induced solid cancer incidence fitted to the LSS epidemiological data have been applied with neutron and γ-ray absorbed doses as separate explanatory covariables. A simple evaluation of the degree of independent effects from γ-ray and neutron absorbed doses on the all solid cancer risk with the hierarchical partitioning (HP) technique is presented here. The degree of multi-collinearity between the γ-ray and neutron absorbed doses has also been considered. The results show that, whereas the partial correlation between the neutron and γ-ray colon absorbed doses may be considered to be high at 0.74, this value is just below the level beyond which remedial action, such as adding the doses together, is usually recommended. The resulting variance inflation factor is 2.2. Applying HP indicates that just under half of the drop in deviance resulting from adding the γ-ray and neutron absorbed doses to the baseline risk model comes from the joint effects of the neutrons and γ-rays-leaving a substantial proportion of this deviance drop accounted for by individual effects of the neutrons and γ-rays. The average ERR/Gy γ-ray absorbed dose and the ERR/Gy neutron absorbed dose that have been obtained here directly for the first time, agree well with previous indirect estimates. The average relative biological effectiveness (RBE) of neutrons relative to γ-rays, calculated directly from fit parameters to the all solid cancer ERR model with both

    In most deaths caused by explosive, the victim's body becomes a depot for fragments of explosive materials, so contributing to the collection of trace evidence which may provide clues about the specific type of device used with explosion. Improvised explosive devices are used which contain "homemade" explosives rather than high explosives because of the relative ease with which such components can be procured. Many methods such as chromatography-mass spectrometry, scanning electron microscopy, stereomicroscopy, capillary electrophoresis are available for use in the identification of explosive residues on objects and bomb fragments. Identification and reconstruction of the distribution of explosive residues on the decedent's body may give additional hints in assessing the position of the victim in relation to the device. Traditionally these residues are retrieved by swabbing the body and clothing during the early phase, at autopsy. Gas chromatography-mass spectrometry and other analytical methods may be used to analyze the material swabbed from the victim body. The histological examination of explosive residues on skin samples collected during the autopsy may reveal significant details. The information about type, quantity and particularly about anatomical distribution of explosive residues obtained utilizing confocal laser scanning microscope (CLSM) together with inductively coupled plasma atomic emission spectrometer (ICP-AES), may provide very significant evidence in the clarification and reconstruction of the explosive-related events.

    This paper is in response to criticism of our article "The human sex odds at birth after the atmospheric atomic bomb tests, after Chernobyl, and in the vicinity of nuclear facilities" published in Environ Sci Pollut Res 18(5):697-707, 2011. Our findings and methods concerning the disturbed human sex odds at birth have been criticized in this journal for being artifacts of data mining, that the concept of statistical significance was misunderstood, and that confounding factors have not been accounted for. Here, we show that this criticism has no basis. We applied well-established statistical methods to large official data sets, and confounding is less important at the level of secular sex odds trends in aggregated annual figures from countries or continents. Moreover, our results are strengthened by recent findings concerning increased infant death sex odds in Germany and increased Down syndrome prevalence at birth across Europe after Chernobyl. Prompted by our studies, an official investigation in Lower Saxony, Germany, by the "Niedersächsisches Landesgesundheitsamt (NLGA)" confirmed our observation of severely escalated sex odds within 40 km distance from the nuclear storage site in Gorleben, Germany.

    Two atomic bombs dropped on Hiroshima and Nagasaki in August 1945 brought the unexpected liberation of Korea from the 35-year Japanese occupation. Koreans therefore had a very favorable and positive image of the nuclear bomb and nuclear energy from the beginning. The image of the nuclear bomb as "savior" was strengthened during the Korean War when the United States openly mentioned the possible use of the nuclear bomb against North Korean and Chinese military. After the end of the Korean War in July 1953 South Koreans strongly supported the development of the nuclear bomb in order to deter another North Korean invasion. When the US government provided South Korea with a research nuclear reactor in the late 1950s, most South Koreans hailed it as the first step to developing their own nuclear bomb. This paper will analyze how and why the savior image of the nuclear bomb originated and spread in Korea during the 1950s.

    Iran is a rational actor in the international politics that decides on the basis of the perception of threat. Iran's security situation is comparable with that of Israel with the rational consequence to rely on the atomic program with respect to deterrence and self-defense. The solution of the Iran crisis is basically dependent on a change of the perception of threat. A military act against the Iranian nuclear facilities would be counterproductive, would only slowing down the program but not prevent further activities. In fact a military act would enhance the perception of threat. For the analysis of the Iran crises the author used the Cuba crisis as blueprint, were mislead perceptions were responsible for the escalation.

  11. Low dose radiation risks for women surviving the a-bombs in Japan: generalized additive model.

    Dropkin, Greg

    2016-11-24

    Analyses of cancer mortality and incidence in Japanese A-bomb survivors have been used to estimate radiation risks, which are generally higher for women. Relative Risk (RR) is usually modelled as a linear function of dose. Extrapolation from data including high doses predicts small risks at low doses. Generalized Additive Models (GAMs) are flexible methods for modelling non-linear behaviour. GAMs are applied to cancer incidence in female low dose subcohorts, using anonymous public data for the 1958 - 1998 Life Span Study, to test for linearity, explore interactions, adjust for the skewed dose distribution, examine significance below 100 mGy, and estimate risks at 10 mGy. For all solid cancer incidence, RR estimated from 0 - 100 mGy and 0 - 20 mGy subcohorts is significantly raised. The response tapers above 150 mGy. At low doses, RR increases with age-at-exposure and decreases with time-since-exposure, the preferred covariate. Using the empirical cumulative distribution of dose improves model fit, and capacity to detect non-linear responses. RR is elevated over wide ranges of covariate values. Results are stable under simulation, or when removing exceptional data cells, or adjusting neutron RBE. Estimates of Excess RR at 10 mGy using the cumulative dose distribution are 10 - 45 times higher than extrapolations from a linear model fitted to the full cohort. Below 100 mGy, quasipoisson models find significant effects for all solid, squamous, uterus, corpus, and thyroid cancers, and for respiratory cancers when age-at-exposure > 35 yrs. Results for the thyroid are compatible with studies of children treated for tinea capitis, and Chernobyl survivors. Results for the uterus are compatible with studies of UK nuclear workers and the Techa River cohort. Non-linear models find large, significant cancer risks for Japanese women exposed to low dose radiation from the atomic bombings. The risks should be reflected in protection standards.

Nuclear proliferation began in the uneasy wartime collaboration of the United States, England, Canada, and Free France to produce the atom bomb. Through the changes of history, a young French chemist had a role in almost every act of this international drama. This memoir is based on Goldschmidt's own recollections, interviews with other leading figures, and 3,000 pages of newly declassified documents in Allied archives. From his own start as Marie Curie's lab assistant, Goldschmidt's career was closely intertwined with Frances complicated rise to membership in the nuclear club. As a refugee from the Nazis, he became part of the wartime nuclear energy project in Canada and found himself the only French scientist to work (although briefly) on the American atom bomb project.

There are only human beings and there is no idol that is different existence from human beings, that is true to be. So the nature we see is zero and we, human beings make the zero nature as from no start and no ending. No alpha and omega mean we are idol and that there is no blackhole. Blackhole means the block is existing in the nothing(as we are no alpha and no omega). So the block cannot be existence. So if there is blackhole, then there must be the wall to block me and never walk again. The big bang and evolution mean they are no alpha and no omega and existing by themselves. So they could be existence, but big bang and evolution are just logical fact to be. We need faith as God give us the direction into our spirit.

    The explosion of atom bombs over the cities of Hiroshima and Nagasaki in August 1945 resulted in very high casualties, both immediate and delayed but also left a large number of survivors who had been exposed to radiation, at levels that could be fairly precisely ascertained. Extensive follow-up of a large cohort of survivors (120,000) and of their offspring (77,000) was initiated in 1947 and continues to this day. In essence, survivors having received 1 Gy irradiation (∼1000 mSV) have a significantly elevated rate of cancer (42% increase) but a limited decrease of longevity (∼1 year), while their offspring show no increased frequency of abnormalities and, so far, no detectable elevation of the mutation rate. Current acceptable exposure levels for the general population and for workers in the nuclear industry have largely been derived from these studies, which have been reported in more than 100 publications. Yet the general public, and indeed most scientists, are unaware of these data: it is widely believed that irradiated survivors suffered a very high cancer burden and dramatically shortened life span, and that their progeny were affected by elevated mutation rates and frequent abnormalities. In this article, I summarize the results and discuss possible reasons for this very striking discrepancy between the facts and general beliefs about this situation.

    The past decade has seen an explosion in use of the {sup 14}C bomb pulse to do fundamental cell biology. Studies in the 1960s used decay counting to measure tissue turnover when the atmospheric {sup 14}C/C concentration was changing rapidly. Today bulk tissue measurements are of marginal interest since most of the carbon in the tissue resides in proteins, lipids and carbohydrates that turn over rapidly. Specific cell types with specialized functions are the focus of cell turnover investigations. Tissue samples need to be fresh or frozen. Fixed or preserved samples contain petroleum-derived carbon that has not been successfully removed. Cell or nuclear surface markers are used to sort specific cell types, typically by fluorescence-activated cell sorting (FACS). Specific biomolecules need to be isolated with high purity and accelerator mass spectrometry (AMS) measurements must accommodate samples that generally contain less than 40 {mu}g of carbon.

Approaches for separating specific proteins and DNA and combating contamination of undesired molecules are described.

  1. Late effects of radiation: Neglected aspects of A-bomb data

    Both from the Oxford Survey of Childhood Cancers, and from recent surveys of nuclear workers at Hanford and Oak Ridge, have come risk estimates for cancer effects of radiation that are much higher than the ones based on a life span study cohort of A-bomb survivors. Furthermore, relations between the age when exposed and the cancer risk were radically different for workers and survivors. Therefore, there was clearly a need to discover whether the LSS cohort was a normal homogeneous population or, alternatively, whether persons who had shown signs of acute radiation effects constituted a special, radiosensitive subgroup of survivors. Statistical tests of the alternative hypotheses revealed significant differences between 63,072 survivors who denied having any of the following injuries and 2,601 survivors who claimed two or more of them: radiation, burns, purpura, oropharyngeal lesions and epilation. The tests also showed that the group differences were largely the result of exposures before 10 or after 55 years of age being exceptionally dangerous; that cancer was not the only late effect of the A-bomb radiation, and that it was only among the survivors with multiple injuries that the leukaemia death rate was exceptionally high.

    On December 7, 1941, a 60-year old dentist from Irwin, Pennsylvania, Dr. Lytle S. Adams, was driving home from a vacation at Carlsbad Caverns in New Mexico. Hours earlier, he had been gripped with amazement as he witnessed millions of bats exiting the caves of Carlsbad. Listening to his car radio on his return trip, he was shocked to hear that Japan had just attacked Pearl Harbor. Dr. Adams, outraged over this travesty, began to mentally construct a plan for U.S. retaliation. As his thoughts returned to the countless bats that had awed him, he formed a tentative plan: millions of these small, flying mammals could be connected to tiny, time-fused incendiary bombs, and then released to land on the flimsily constructed structures which dotted the cities of Japan. Within a few minutes, the bombs would explode and enflame the entire urban areas. He postulated that these immeasurable numbers of fires, spreading their devastation over such vast areas within Japanese cities would result in the enemy's speedy surrender. This article documents the futile efforts of Dr. Adams, his team and the U.S. government to develop and employ an effective, incendiary bat bomb. The recently developed atom bomb, a far more deadly weapon was used in its place.

    Disasters disrupt everyone's lives, and they can disrupt the flow and function of an OR as well as affect personnel on a professional and personal level even though perioperative departments and their personnel are used to caring for trauma patients and coping with surprises. The Boston Marathon bombing was a new experience for personnel at Massachusetts General Hospital, Boston. This article discusses the incidents surrounding the bombing and how personnel at this hospital met the challenge of caring for patients and the changes we made after the experience to be better prepared in the event a response to a similar incident is needed.

    Recent progress towards the non-fission ignition of thermonuclear micro-explosions raises the prospect for a revival of the nuclear bomb propulsion idea, both for the fast transport of large payloads within the solar system and the launch into earth orbit without the release of fission products into the atmosphere. To reach this goal three areas of research are of importance: 1)Compact thermonuclear ignition drivers. 2)Fast ignition and deuterium burn. 3)Space-craft architecture involving mag...

    Epidemiological data on the health effects of A-bomb radiation in Hiroshima and Nagasaki provide the framework for setting limits for radiation risk and radiological protection. However, uncertainty remains in the equivalent dose, because it is generally believed that direct derivation of the relative biological effectiveness (RBE) of neutrons from the epidemiological data on the survivors is difficult. To solve this problem, an alternative approach has been taken. The RBE of polyenergetic neutrons was determined for chromosome aberration formation in human lymphocytes irradiated in vitro, compared with published data for tumor induction in experimental animals, and validated using epidemiological data from A-bomb survivors. The RBE of fission neutrons was dependent on dose but was independent of the energy spectrum. The same RBE regimen was observed for lymphocyte chromosome aberrations and tumors in mice and rats. Used as a weighting factor for A-bomb survivors, this RBE system was superior in eliminating the city difference in chromosome aberration frequencies and cancer mortality. The revision of the equivalent dose of A-bomb radiation using DS02 weighted by this RBE system reduces the cancer risk by a factor of 0.7 compared with the current estimates using DS86, with neutrons weighted by a constant RBE of 10.

  8. Patenting the bomb: nuclear weapons, intellectual property, and technological control.

    2008-03-01

    During the course of the Manhattan Project, the U.S. government secretly attempted to acquire a monopoly on the patent rights for inventions used in the production of nuclear weapons and nuclear energy. The use of patents as a system of control, while common for more mundane technologies, would seem at first glance to conflict with the regimes of secrecy that have traditionally been associated with nuclear weapons. In explaining the origins and operations of the Manhattan Project patent system, though, this essay argues that the utilization of patents was an ad hoc attempt at legal control of the atomic bomb by Manhattan Project administrators, focused on the monopolistic aspects of the patent system and preexisting patent secrecy legislation. From the present perspective, using patents as a method of control for such weapons seems inadequate, if not unnecessary; but at the time, when the bomb was a new and essentially unregulated technology, patents played an important role in the thinking of project administrators concerned with meaningful postwar control of the bomb.

    The American composer John Adams uses opera to dramatize controversial current events. His 1987 work Nixon in China was about the landmark meeting in 1972 between US President Richard Nixon and Chairman Mao Zedong of China; The Death of Klinghoffer (1991) was a musical re-enactment of an incident in 1985 when Palestinian terrorists kidnapped and murdered a wheelchair-bound Jewish tourist on a cruise ship. Adams's latest opera, Doctor Atomic, is also tied to a controversial event: the first atomic-bomb test in Alamogordo, New Mexico, on 16 June 1945. The opera premièred in San Francisco in 2005, had a highly publicized debut at the Metropolitan Opera in New York in 2008, and will have another debut on 25 February - with essentially the same cast - at the English National Opera in London.

    2009-01-01

    Following the London bombings of 7 July 2005 a “screen and treat” program was set up with the aim of providing rapid treatment for psychological responses in individuals directly affected. The present study found that 45% of the 596 respondents to the screening program reported phobic fear of public transport in a screening questionnaire. The screening program identified 255 bombing survivors who needed treatment for a psychological disorder. Of these, 20 (8%) suffered from clinically significant travel phobia. However, many of these individuals also reported symptoms of posttraumatic stress disorder [PTSD]. Comparisons between the travel phobia group and a sex-matched group of bombing survivors with PTSD showed that the travel phobic group reported fewer re-experiencing and arousal symptoms on the Trauma Screening Questionnaire (Brewin et al., 2002). The only PTSD symptoms that differentiated the groups were anger problems and feeling upset by reminders of the bombings. There was no difference between the groups in the reported severity of trauma or in presence of daily transport difficulties. Implications of these results for future trauma response are discussed.

    Was the first Soviet thermonuclear device really a step in the wrong direction? No bomb design has been as much maligned or otherwise disparaged as the first Soviet thermonuclear weapon. Detonated in August 1953, the bomb, officially tested under the name RDS-6s but usually known as Sloika or "layer cake" (the name Andrei Sakharov coined for it), was nothing to sneeze at. Shown in Figure 1 and able to be dropped from aircraft, it released the explosive equivalent, or yield, of almost half a megaton of TNT. The result was a blazing fireball with 20 times the power of the bomb that leveled Nagasaki, Japan.

    Science.gov (United States)

    Berlicki, A.; Heinzel, P.; Avrett, E. H.

    Observations of Ellerman bombs (EBs) show them as short-lived, compact, and spatially localized emissions that are well observable in the wings of the Halpha hydrogen line. The Halpha line profiles of EBs are characterized by deep absorption at the line center and enhanced emission in the wings with maximum around ± 1 Å from the line center, fading beyond ± 5 Å. EBs may also be observed in the chromospheric Ca II lines and in the UV as bright points often located within active regions. Previous work suggests that EBs may be considered as micro-flares and may contribute significantly to the heating of the lower chromosphere in newly emerging magnetic flux regions. However, it is still not clear at what height in the solar atmosphere the emission of EBs originates. In our analysis we used observations of EBs obtained in the Halpha line with the Dutch Open Telescope (DOT) and in the UV range with the TRACE 1600 Å channel. These one-hour long simultaneous sequences obtained with high temporal and spatial resolution were used to analyze the relation between the emission in the Halpha line and at 1600 Å. The observations show fast variations of EB emission in both channels. Comparison between the observed emission in Halpha and at 1600 Å and theoretical calculations allowed us to draw conclusions about the vertical structure of EBs.

  19. Forensic Seismology: constraints on terrorist bombings

    Science.gov (United States)

    Wallace, T. C.; Koper, K. D.

    2002-05-01

    Seismology has long been used as a tool to monitor and investigate explosions, both accidental and intentional. Seismic records can be used to provide a precise chronology of events, estimate the energy release in explosions and produce constraints to test various scenarios for the explosions. Truck bombs are a popular tool of terrorists, and at least two such attacks have been recorded seismically. On August 7, 1998 a truck bomb was detonated near the US embassy in Nairobi, Kenya. The bomb seriously damaging a dozen buildings, injuring more than 4000 people and causing 220 fatalities. The explosion was recorded on a short-period seismometer located north of the blast site; the blast seismogram contained body waves, Rayleigh waves and vibrations associated with the air blast. Modeling of the body and surfaces wave allowed an estimate of the origin time of the bombing, which it turn could be used as a constraint the timing of the air blasts. The speed of the air waves from an explosion depend on the air temperature and the size, or yield, of the explosion. In an effort to fully utilize the seismic recordings from such attacks, we analyzed the seismic records from a series of controlled truck bomb explosions carried out at White Sand Missile Range in New Mexico. We developed a new set of scaling laws that relate seismic and acoustic observations directly to the explosive mass (yield). These relationships give a yield of approximately 3000 kg of TNT equivalent for the Nairobi bomb. The terrorist bombing of the Murrah Federal Building in Oklahoma City in 1995 was also recorded on seismometers. One of these records showed 2 discrete surface wavetrains separated by approximately 10 seconds. Some groups seized on the seismic recordings as evidence that there were 2 explosions, and that the US government was actually behind the bombing. However, the USGS monitored the demolition of the remainder of the Murrah Building and showed that the collapse also produced 2 surface

    2015-01-01

    At the beginning of the 20th century the collective imagination was fascinated and terrified by the discovery of radium. A scientific imagery sprang up around radioactivity and was disseminated by public lectures and newspaper articles discussing the ambiguous power of this strange substance. It was claimed that radium could be used to treat cholera, typhus and tuberculosis, but at the same time there were warnings that it could be used for military purposes. The media and the scientists themselves employed a rich vocabulary influenced by religion, alchemy and magic. The ambivalent power of radioactive elements exerted a great influence on science fiction novelists. This paper will examine some significant works published in Europe, America and Russia during the first decades of the 20th century and their role in the creation of the complex imagery of radioactivity that seized the public imagination long before the invention of the atomic bomb.

    This paper is an expanded version of the author's talk presented at a session of the Physical Sciences Division of the Russian Academy of Sciences celebrating the 100th anniversary of V L Ginzburg's birth. Tamm's Special group was organized in June 1948 with the task to clarify the feasibility of constructing a hydrogen bomb. Having verified and confirmed the calculated results by Ya B Zel'dovich's group, the Tamm group proposed an original hydrogen bomb design, which, following A D Sakharov's idea, consisted of an atomic bomb surrounded spherically by nested uranium and heavy water layers: the heavy water, on V L Ginzburg's suggestion, was replaced by higher-calorie solid lithium-6 deuteride. The ionization implosion of deuterium by uranium, both heated by the atomic bomb's explosion, greatly accelerates nuclear reactions in deuterium and uranium and increases the total energy release. Upon their approval by the KB-11 top researchers, the Atomic project leadership, and the government, the proposals were implemented in the RDS-6s bomb, which was successfully tested on 12 August 1953. Lithium-6 deuteride turned out to be a convenient multipurpose nuclear fuel. The paper highlights the recognition by the leaders of the country and of the Atomic project that fundamental science plays a crucial role in promoting scientists' ideas and proposals.

    Terrorists have used the explosive device successfully globally, with their effects extending beyond the resulting injuries. Suicide bombings, in particular, are being increasingly deployed due to the devastating effect of a combination of high lethality and target accuracy. The aim of this study was to identify trends and analyse the demographics and casualty figures of terrorist bombings worldwide. Analysis of the Global Terrorism Database (GTD) and a PubMed/Embase literature search (keywords "terrorist", and/or "suicide", and/or "bombing") from 1970 to 2014 was performed. 58,095 terrorist explosions worldwide were identified in the GTD. 5.08% were suicide bombings. Incidents per year are increasing (PEurope (13.2%) ranked 4th. The literature search identified 41 publications reporting 167 incidents of which 3.9% detailed building collapse (BC), 60.8% confined space (CS), 23.5% open space (OS) and 11.8% semi-confined space (SC) attacks. 60.4% reported on suicide terrorist attacks. Overall 32 deaths and 180 injuries per incident were seen, however significantly more deaths occurred in explosions associated with a BC. Comparing OS and CS no difference in the deaths per incident was seen, 14.2(SD±17.828) and 15.63 (SD±10.071) respectively. However OS explosions resulted in significantly more injuries, 192.7 (SD±141.147), compared to CS, 79.20 (SD±59.8). Extremity related wounds were the commonest injuries seen (32%). Terrorist bombings continue to be a threat and are increasing particularly in the Middle East. Initial reports, generated immediately at the scene by experienced coordination, on the type of detonation (suicide versus non-suicide), the environment of detonation (confined, open, building collapse) and the number of fatalities, and utilising the Kill:Wounded ratios found in this meta-analysis, can be used to predict the number of casualties and their likely injury profile of survivors to guide the immediate response by the medical services and the

    Nuclear weapons remain for a long time in the hands of the five big powers: USA, Soviet Union, Great Britain, France and China. Things started to change when Israel, and then India acquired the atomic bomb as well. Pakistan took up the race too but Abdul Qadeer Khan, one of the nuclear program maker of the country, took profit of the situation to set up a huge international proliferation network for the spreading of the technologies, tools and materials necessary for weapons fabrication. He offered his services not only to Iran and North Korea, but to Iraq and Libya as well and probably to some other countries. Today, the Iranian nuclear program generates both envy and fear in the Middle East. Who is going to be the next domino of the nuclear game? Egypt, Saudi Arabia, Algeria and Turkey are potential candidates. But while Pakistan sinks into crisis, the terrorists are taking interest in nukes. The author of this book has worked for more than 10 years on this dossier. He has had access to the most sensible documents and to essential testimonies. He now lifts the curtain on the secrets of nuclear proliferation. In this book, where reality sometimes surpasses fiction, he explains how the CIA finally succeeded in infiltrating the 'Khan ring' after having closed its eyes on his deals for a long time. He describes the branches of the Pakistani atomic complex and analyses with lucidity the nuclear terrorism risk.

    An undergraduate-level derivation of the probability that a uranium or plutonium fission bomb will suffer an uncontrolled predetonation due to neutrons liberated in spontaneous fissions in the fissile material is developed. Consistent with what was learned by Los Alamos bomb designers during World War II, it is shown why uncontrolled predetonation was not a problem for a U-235 bomb of the Little Boy "gun" design but necessitated development of implosion engineering for the Pu-239 Trinity and Fat Man bombs where the cores were contaminated with highly spontaneously fissile Pu-240.

    In a letter dated 6 January 2009, the Danish foreign minister, Per Stig Møller, asked DIIS to draw up a report based on the documentary evidence concerning the 1968 crash of a B-52 bomber on the sea ice a few miles from Thule Air Base in Northwestern Greenland. The B-52 had four hydrogen bombs on board. For more than four decades, the official American and Danish explanations have consistently stated that all four nuclear weapons were destroyed in the accident. The foreign minister's initiati...

  17. Determination of calorific values of forest waste biomass by static bomb calorimetry

    Calorific values of forest waste originating from forestry works such as woodland cleaning, reaforestation and, all other silviculture tasks, were measured by static bomb calorimetry. These waste materials, heretofore considered as useless refuse, are beginning to be used as alternative fuels in wide social sectors all over the world. Two of the main forest species, eucalyptus (E. globulus Labill) and pine (P. pinaster Aiton) existing in Galicia (NW Spain), are included in this study. The experimental procedure was based on that proposed by Hubbard et al. [Experimental Thermochemistry, Interscience, New York, 1956, p. 5]. Simultaneously, some other parameters such as elementary chemical composition and heavy metal contents, moisture, density, and ash percentage after combustion in the bomb, were also determined. The experimental results, with calorific values exceeding 20000kJkg{sup -1}, make it advisable to use these materials as alternative fuels. The different parameters were measured using, as main equipment, a bomb calorimeter with an oxygen atmosphere, an elementary analysis equipment, and an atomic absorption spectrophotometer.

    2000-02-01

    The bomb in Omagh on the 15th August 1998 was responsible for the largest loss of life of any single terrorist incident in the whole of the "Troubles" in Northern Ireland. However, the medical response to this tragedy provided an excellent opportunity for the civilian and military agencies to work together. As a consequence of this a number of lessons were drawn which are presented in the paper. Whatever the outcome of the peace process these lessons will have an important role in the future, since history would suggest that there is little possibility of the terrorist threat ever completely.

    This report describes the problems, issues, and history of the H1347 bomb hand truck for the B83 bomb after the bomb was put into stockpile in the mid-1980s. Major issues that were reported in Unsatisfactory Reports (URs) were cracking problems on stacking fixture welds, cracked welds on the caster bracket receptacles on the cradle, cracked caster mounting brackets, casters unlocking from the swivel lock position, and caster tires rubbing and binding on the stacking frame. Resolution of these and other problems is described. The introduction of the H695B storage-only bomb hand truck to alleviate a shortage of bomb hand trucks in the mid-1990s is described. The development and qualification of the H1347A bomb hand truck as a replacement for the H695 B is covered. The results from load test evaluations on the stacking fixture, cradle, and casters for the H1347 are described along with towing results on one and two-high stack configurations of B83 bombs in bomb hand trucks. New towing and truck/trailer transport procedures are described. Development, evaluation, and production recommendations for a stronger caster mounting bracket are described.

  3. Hα features with hot onsets. I. Ellerman bombs

    2016-05-01

    Ellerman bombs are transient brightenings of the wings of the Balmer lines that uniquely mark reconnection in the solar photosphere. They are also bright in strong Ca II and ultraviolet lines and in ultraviolet continua, but they are not visible in the optical continuum and the Na I D and Mg I b lines. These discordant visibilities invalidate all published Ellerman bomb modeling. I argue that the assumption of Saha-Boltzmann lower-level populations is informative to estimate bomb-onset opacities for these diverse diagnostics, even and especially for Hα, and employ such estimates to gauge the visibilities of Ellerman bomb onsets in all of them. They constrain Ellerman bomb formation to temperatures 10 000-20 000 K and hydrogen densities around 1015 cm-3. Similar arguments likely hold for Hα visibility in other transient phenomena with hot and dense onsets.

    2017-03-01

    The modern military battlefields are characterized by the use of nonconventional weapons such as encountered in the conflicts of the Gulf War I and Gulf War II. Recent warfare in Iraq, Afghanistan, and the Balkans has introduced radioactive weapons to the modern war zone scenarios. This presents the military medicine with a new area of radioactive warfare with the potential large scale contamination of military and civilian targets with the variety of radioactive isotopes further enhanced by the clandestine use of radioactive materials in the terrorist radioactive warfare. Radioactive dispersal devices (RDDs), including the "dirty bomb," involve the use of organotropic radioisotopes such as iodine 131, cesium 137, strontium 90, and transuranic elements. Some of the current studies of RDDs involve large-scale medical effects, social and economic disruption of the society, logistics of casualty management, cleanup, and transportation preparedness, still insufficiently addressed by the environmental and mass casualty medicine. The consequences of a dirty bomb, particularly in the terrorist use in urban areas, are a subject of international studies of multiple agencies involved in the management of disaster medicine. The long-term somatic and genetic impact of some from among over 400 radioisotopes released in the nuclear fission include somatic and transgenerational genetic effects with the potential challenges of the genomic stability of the biosphere. The global contamination is additionally heightened by the presence of transuranic elements in the modern warzone, including depleted uranium recently found to contain plutonium 239, possibly the most dangerous substance known to man with one pound of plutonium capable of causing 8 billion cancers. The planning for the consequences of radioactive dirty bomb are being currently studied in reference to the alkaline earths, osteotropic, and stem cell hazards of internally deposited radioactive isotopes, in particular

    2011-07-01

    Full Text Available Abstract Background and Purpose Most information on the dose-response of radiation-induced cancer is derived from data on the A-bomb survivors. Since, for radiation protection purposes, the dose span of main interest is between zero and one Gy, the analysis of the A-bomb survivors is usually focused on this range. However, estimates of cancer risk for doses larger than one Gy are becoming more important for radiotherapy patients. Therefore in this work, emphasis is placed on doses relevant for radiotherapy with respect to radiation induced solid cancer. Materials and methods For various organs and tissues the analysis of cancer induction was extended by an attempted combination of the linear-no-threshold model from the A-bomb survivors in the low dose range and the cancer risk data of patients receiving radiotherapy for Hodgkin's disease in the high dose range. The data were fitted using organ equivalent dose (OED calculated for a group of different dose-response models including a linear model, a model including fractionation, a bell-shaped model and a plateau-dose-response relationship. Results The quality of the applied fits shows that the linear model fits best colon, cervix and skin. All other organs are best fitted by the model including fractionation indicating that the repopulation/repair ability of tissue is neither 0 nor 100% but somewhere in between. Bone and soft tissue sarcoma were fitted well by all the models. In the low dose range beyond 1 Gy sarcoma risk is negligible. For increasing dose, sarcoma risk increases rapidly and reaches a plateau at around 30 Gy.

    Ellerman Bombs (EBs) are thought to arise as a result of photospheric magnetic reconnection. We use data from the Swedish 1 m Solar Telescope to study EB events on the solar disk and at the limb. Both data sets show that EBs are connected to the foot points of forming chromospheric jets. The limb observations show that a bright structure in the Hα blue wing connects to the EB initially fueling it, leading to the ejection of material upwards. The material moves along a loop structure where a newly formed jet is subsequently observed in the red wing of Hα. In the disk data set, an EB initiates a jet which propagates away from the apparent reconnection site within the EB flame. The EB then splits into two, with associated brightenings in the inter-granular lanes. Micro-jets are then observed, extending to 500 km with a lifetime of a few minutes. Observed velocities of the micro-jets are approximately 5–10 km s{sup −1}, while their chromospheric counterparts range from 50 to 80 km s{sup −1}. MURaM simulations of quiet Sun reconnection show that micro-jets with properties similar to those of the observations follow the line of reconnection in the photosphere, with associated Hα brightening at the location of increased temperature.

    Brown, Matthew Rd; Ramirez, Juan D; Farquhar-Smith, Paul

    2014-11-01

    Cancer and its treatment exert a heavy psychological and physical toll. Of the myriad symptoms which result, pain is common, encountered in between 30% and 60% of cancer survivors. Pain in cancer survivors is a major and growing problem, impeding the recovery and rehabilitation of patients who have beaten cancer and negatively impacting on cancer patients' quality of life, work prospects and mental health. Persistent pain in cancer survivors remains challenging to treat successfully. Pain can arise both due to the underlying disease and the various treatments the patient has been subjected to. Chemotherapy causes painful chemotherapy-induced peripheral neuropathy (CIPN), radiotherapy can produce late effect radiation toxicity and surgery may lead to the development of persistent post-surgical pain syndromes. This review explores a selection of the common causes of persistent pain in cancer survivors, detailing our current understanding of the pathophysiology and outlining both the clinical manifestations of individual pain states and the treatment options available.

    Full Text Available Abstract Introduction Critical hospital resources, especially the demand for ICU beds, are usually limited following mass casualty incidents such as suicide bombing attacks (SBA. Our primary objective was to identify easily diagnosed external signs of injury that will serve as indicators of the need for ICU admission. Our secondary objective was to analyze under- and over-triage following suicidal bombing attacks. Methods A database was collected prospectively from patients who were admitted to Hadassah University Hospital Level I Trauma Centre, Jerusalem, Israel from August 2001-August 2005 following a SBA. One hundred and sixty four victims of 17 suicide bombing attacks were divided into two groups according to ICU and non-ICU admission. Results There were 86 patients in the ICU group (52.4% and 78 patients in the non-ICU group (47.6%. Patients in the ICU group required significantly more operating room time compared with patients in the non-ICU group (59.3% vs. 25.6%, respectively, p = 0.0003. For the ICU group, median ICU stay was 4 days (IQR 2 to 8.25 days. On multivariable analysis only the presence of facial fractures (p = 0.014, peripheral vascular injury (p = 0.015, injury ≥ 4 body areas (p = 0.002 and skull fractures (p = 0.017 were found to be independent predictors of the need for ICU admission. Sixteen survivors (19.5% in the ICU group were admitted to the ICU for one day only (ICU-LOS = 1 and were defined as over-triaged. Median ISS for this group was significantly lower compared with patients who were admitted to the ICU for > 1 day (ICU-LOS > 1. This group of over-triaged patients could not be distinguished from the other ICU patients based on external signs of trauma. None of the patients in the non-ICU group were subsequently transferred to the ICU. Conclusions Our results show that following SBA, injury to ≥ 4 areas, and certain types of injuries such as facial and skull fractures, and peripheral vascular injury, can serve

    2017-03-01

    Full Text Available This paper examines an Australian newspaper’s coverage of the bombing of an export port terminal in Bunbury, Western Australia on 19 July, 1976. We wanted to see how The West Australian newspaper framed the story, its precursor events, and the events that followed. We were particularly interested in whether the bombing was reported as an act of terrorism because the then Premier of Western Australia, Sir Charles Court, immediately decried it as “a gross act of terrorism.” We find the newspaper resisted the lure to apply this label, and couched the story in terms of serious criminality. However, it did so before the 1978 Hilton Hotel bombing; an event the news media heralded as the “arrival” of terrorism in Australia. Also, this occurred before what could be argued the sensationalist and politicised reporting of terror-related events became normalised.

    After a brief review of the basics of {sup 14}C bomb-pulse dating, this paper presents two unique forensic applications. Particular attention is dedicated to the use of the {sup 14}C bomb-pulse to establish the time of harvest of illicit drugs such as heroin and opium. Preliminary measurements of {sup 14}C concentrations in milligram samples taken from seized drugs are presented. {sup 14}C bomb-pulse dating can determine whether drug distribution originates from stockpiles or recent manufacture, and support the action of law enforcement authorities against criminal organisations involved in drug trafficking. In addition, we describe the dating of wine vintages for a number of authenticated single label vintage red wines from the Barossa Valley - South Australia. Our results show that radiocarbon dating can be used to accurately determine wine vintages and therefore reveal the addition of unrelated materials of natural and synthetic origin.

    2013-01-01

    Background Experiencing potentially traumatic events is associated with psychological distress. However, some survivors also experience positive personal and psychological changes in the aftermath of trauma. Methods The present study investigated perceived posttraumatic growth in 197 ministerial employees who were present at work during the 2011 Oslo bombing attack. The relationships between trauma-exposure, peritraumatic reactions and posttraumatic growth were studied. Moreover, the adaptive significance of posttraumatic growth was addressed. Results The results showed that higher levels of trauma-exposure and immediate reactions were significantly related to perceived posttraumatic growth. No support for an adaptive significance of posttraumatic growth was found. On the contrary, posttraumatic growth was associated with higher symptom levels of posttraumatic stress. After adjusting for posttraumatic stress symptoms no association was found between perceived growth and work and social adjustment. However, perceived growth was associated with higher levels of life satisfaction. Conclusion The present results are in line with previous findings indicating that perceived growth may be unrelated to psychological adjustment, and suggest that the concept and significance of posttraumatic growth should be interpreted with caution.

  3. Rapid intercontinental air pollution transport associated with a meteorological bomb

    2003-01-01

    Full Text Available Intercontinental transport (ICT of trace substances normally occurs on timescales ranging from a few days to several weeks. In this paper an extraordinary episode in November 2001 is presented, where pollution transport across the North Atlantic took only about one day. The transport mechanism, termed here an intercontinental pollution express highway because of the high wind speeds, was exceptional, as it involved an explosively generated cyclone, a so-called meteorological "bomb''. To the authors' knowledge, this is the first study describing pollution transport in a bomb. The discovery of this event was based on tracer transport model calculations and satellite measurements of NO2, a species with a relatively short lifetime in the atmosphere, which could be transported that far only because of the high wind speeds produced by the bomb. A 15-year transport climatology shows that intercontinental express highways are about four times more frequent in winter than in summer, in agreement with bomb climatologies. The climatology furthermore suggests that intercontinental express highways may be important for the budget of short-lived substances in the remote troposphere. For instance, for a substance with a lifetime of 1 day, express highways may be responsible for about two thirds of the total ICT. We roughly estimate that express highways connecting North America with Europe enhance the average NOx mixing ratios over Europe, due to North American emissions, by about 2-3 pptv in winter.

    Context. Ellerman bombs (EBs) are short-lived, compact, and spatially well localized emission structures that are observed well in the wings of the hydrogen Hα line. EBs are also observed in the chromospheric CaII lines and in UV continua as bright points located within active regions. Hα line profiles of EBs show a deep absorption at the line center and enhanced emission in the line wings with maxima around ±1 Å from the line center. Similar shapes of the line profiles are observed for the CaII IR line at 8542 Å. In CaII H and K lines the emission peaks are much stronger, and EBs emission is also enhanced in the line center. Aims: It is generally accepted that EBs may be considered as compact microflares located in lower solar atmosphere that contribute to the heating of these low-lying regions, close to the temperature minimum of the atmosphere. However, it is still not clear where exactly the emission of EBs is formed in the solar atmosphere. High-resolution spectrophotometric observations of EBs were used for determining of their physical parameters and construction of semi-empirical models. Obtained models allow us to determine the position of EBs in the solar atmosphere, as well as the vertical structure of the activated EB atmosphere Methods: In our analysis we used observations of EBs obtained in the Hα and CaII H lines with the Dutch Open Telescope (DOT). These one-hour long simultaneous sequences obtained with high temporal and spatial resolution were used to determine the line emissions. To analyze them, we used NLTE numerical codes for the construction of grids of 243 semi-empirical models simulating EBs structures. In this way, the observed emission could be compared with the synthetic line spectra calculated for all such models. Results: For a specific model we found reasonable agreement between the observed and theoretical emission and thus we consider such model as a good approximation to EBs atmospheres. This model is characterized by an

    2015-05-01

    Bomb-detecting dogs are trained to detect explosives through their sense of smell and often perform a specific behavior to indicate a possible bomb detection. This behavior is noticed by the dog handler, who confirms the probable explosives, determines the location, and forwards the information to an explosive ordnance disposal (EOD) team. To improve the speed and accuracy of this process and better integrate it with the EOD team's robotic explosive disposal operation, SPAWAR Systems Center Pacific has designed and prototyped an electronic dog collar that automatically tracks the dog's location and attitude, detects the indicative behavior, and records the data. To account for the differences between dogs, a 5-minute training routine can be executed before the mission to establish initial values for the k-mean clustering algorithm that classifies a specific dog's behavior. The recorded data include GPS location of the suspected bomb, the path the dog took to approach this location, and a video clip covering the detection event. The dog handler reviews and confirms the data before it is packaged up and forwarded on to the EOD team. The EOD team uses the video clip to better identify the type of bomb and for awareness of the surrounding environment before they arrive at the scene. Before the robotic neutralization operation commences at the site, the location and path data (which are supplied in a format understandable by the next-generation EOD robots—the Advanced EOD Robotic System) can be loaded into the robotic controller to automatically guide the robot to the bomb site. This paper describes the project with emphasis on the dog-collar hardware, behavior-classification software, and feasibility testing.

    This study examines the types of news stories that include comments by everyday cancer survivors and the messages or information these individuals provide. Even though these non-celebrity survivors increasingly serve on the front lines of cancer prevention and advocacy efforts and often engage with media, the role they play in the media discourse on cancer has not been a focus of research. We conducted a thematic content analysis of print news articles of non-celebrity cancer survivors in 15 leading national daily newspapers for four consecutive months starting in June 2005 to identify the issues or events that included a survivor perspective and the messages or information conveyed by the everyday survivors. Journalists included survivor commentary primarily when covering cancer fundraising events and when focusing on individual survivorship stories. In overall news coverage involving survivors, breast and prostate cancers received the greatest attention, followed by blood and lung cancers. Survivors spoke mainly about the diagnosis experience and life post-cancer. Our analysis of survivors' comments revealed that discussions of the diagnosis experience often convey fear and a lack of confidence in cancer screening practices, while cancer is portrayed as a positive life event. While evidence of a positive and hopeful portrayal of survivorship is an encouraging finding for continued efforts to decrease stigma associated with a cancer diagnosis and for the public understanding of the disease, it is important to consider potential negative implications of an idealized and restricted media discourse on survivorship. The increasing size and capacity of the survivor community offers opportunities for the cancer advocacy community to consider how news media portrayal of cancer and survivorship may contribute in both positive and potentially detrimental ways to public understanding of this disease, its survivors and life after cancer.

    World War II is often seen as a victory for democracy, but at the same time represents the final bankruptcy of those humanistic ideas that seemed so deeply rooted in European tradition. This affected not only the self-perception of the Germans, as obvious, but also that of the winning democracies...... involves questions as: Was the British bombing campaign legitimate to the very end of the war? Do the Germans have any right to commemorate their being victim to the allied air raids, considering the Holocaust and the German conduct towards other countries? How can experiences like this even be remembered......? And which lesson is to be learnt by this – does it affect the European conduct in international conflicts? In order to provide some background information to understand this debate, the paper will give an outline of the background and the extent of the bombings, including the development of the concept...

    The relationship between the Bali (Indonesia) bombings of October 2002 and suicide has not previously been investigated, despite anecdotal evidence of the economic and psychological consequences of these attacks. Suicide rates were calculated over the period 1994-2006 in three Bali regencies to determine whether suicide increased in the period following the first Bali bombings. Poisson regression and time-series models were used to assess the change in suicide rates by sex, age and area in the periods before and after October 2002. Suicide rates (age-adjusted) increased in males from an average of 2.84 (per 100 000) in the period pre-2002 to 8.10 in the period post-2002, and for females from 1.51 to 3.68. The greatest increases in suicide in the post-2002 period were in the age groups 20-29 and 60 years, for both males and females. Tourist arrivals fell significantly after the bombings, and addition of tourism to models reduced relative risk estimates of suicide, suggesting that some of the increase may be attributable to the socio-economic effects of declines in tourism. There was an almost fourfold increase in male suicide risk and a threefold increase in female suicide risk in the period following the 2002 bombings in Bali. Trends in tourism did not account for most of the observed increases. Other factors such as indirect socio-economic effects and Balinese notions of collective guilt and anxieties relating to ritual neglect are important in understanding the rise in suicide in the post-2002 period.

    Zinc chloride (ZnCl2)-based smoke bombs and screens are in use since the Second World War (1939-1945). Many case descriptions on ZnCl2 smoke inhalation incidents appeared since 1945. We provide a comprehensive overview of the clinical symptoms and underlying pathophysiology due to exposure to fumes from ZnCl2 smoke producing bombs. In addition, we give a historical overview of treatment regimens and their outcomes. We performed a literature search on Medline, Scopus and Google Scholar databases using combinations of the following search terms "smoke bomb", "smoke screen", "ZnCl2", "intoxication", "poisoning", "case report", "HE smoke", "hexachloroethane smoke", "smoke inhalation" and "white smoke". We retrieved additional reports based on the primary hits. We collected 30 case reports from the last seven decades encompassing 376 patients, 23 of whom died. Of all the patient descriptions, 31 were of sufficient detail for prudent analysis. Intoxication with clinical signs mainly took place in war situations and in military and fire emergency training sessions in enclosed spaces. Symptoms follow a biphasic course mainly characterised by dyspnoea, coughing and lacrimation, related to irritation of the airways in the first six hours, followed by reappearance of early signs complemented with inflammation related signs and tachycardia from 24 h onwards. Acute respiratory stress syndrome developed in severely affected individuals. Chest radiographs did not always correspond with clinical symptoms. Common therapy comprises corticosteroids, antibiotics and supplemental oxygen or positive pressure ventilation in 64% of the cases. Of the 31 patients included, eight died, three had permanent lung damage and 15 showed complete recovery, whereas in five patients outcome was not reported. Early signs likely relate to caustic reactions in the airway lining, whereas inhaled ZnCl2 particles may trigger an inflammatory response and associated delayed fibrotic lung damage. Smoke bomb

    The Boston Marathon bombing was the first major, modern US terrorist event with multiple, severe lower extremity injuries. First responders, including trained professionals and civilian bystanders, rushed to aid the injured. The purpose of this review was to determine how severely bleeding extremity injuries were treated in the prehospital setting in the aftermath of the Boston Marathon bombing. A database was created and populated by all the Boston Level I trauma centers following the Boston Marathon bombing. Data regarding specific injuries, extremities affected, demographics, prehospital interventions (including tourniquet types), and outcomes were extracted. Of 243 injured, 152 patients presented to the emergency department within 24 hours. Of these 152 patients, there were 66 (63.6% female) experiencing at least one extremity injury, with age ranging from younger than 15 years to 71 years, and with a median Injury Severity Score (ISS) of 10 (range, 1-38). Of the 66 injured patients, 4 had upper limbs affected, 56 had injuries on the lower limbs only, and 6 had combined upper and lower limbs affected. The extremity Abbreviated Injury Scale (AIS) scores had a median of 3 (range, 1-4). There were 17 lower extremity traumatic amputations in 15 patients. In addition, there were 10 patients with 12 lower extremities experiencing major vascular injuries. Of 66 injured patients, 29 patients had recognized extremity exsanguination at the scene. In total, 27 tourniquets were applied: 16 of 17 traumatic amputations, 5 of 12 lower extremities with major vascular injuries, and 6 additional limbs with major soft tissue injury. All tourniquets were improvised, and no commercial, purpose-designed tourniquets were identified. Among all 243 patients, mortality was 0%. After the Boston Marathon bombings, extremity exsanguination at the point of injury was either left untreated or treated with an improvised tourniquet in the prehospital environment.

    Rockfishes (Sebastes spp.) support one of the most economically important fisheries of the Pacific Northwest and it is essential for sustainable management that age estimation procedures be validated for these species. Atmospheric testing of thermonuclear devices during the 1950s and 1960s created a global radiocarbon ({sup 14}C) signal in the ocean environment that scientists have identified as a useful tracer and chronological marker in natural systems. In this study, we first demonstrated that fewer samples are necessary for age validation using the bomb-generated {sup 14}C signal by emphasizing the utility of the time-specific marker created by the initial rise of bomb-{sup 14}C. Second, the bomb-generated {sup 14}C signal retained in fish otoliths was used to validate the age and age estimation methodology of the quillback rockfish (Sebastes maliger) in the waters of southeast Alaska. Radiocarbon values from the first year's growth of quillback rockfish otoliths were plotted against estimated birth year producing a {sup 14}C time series spanning 1950 to 1985. The initial rise of bomb-{sup 14}C from pre-bomb levels ({approx} -90 {per_thousand}) occurred in 1959 {+-} 1 year and {sup 14}C levels rose relatively rapidly to peak {Delta}{sup 14}C values in 1967 (+105.4 {per_thousand}), with a subsequent declining trend through the end of the record in 1985 (+15.4 {per_thousand}). The agreement between the year of initial rise of {sup 14}C levels from the quillback rockfish record and the chronometer determined for the waters of southeast Alaska from yelloweye rockfish (S. ruberrimus) otoliths validated the ageing methodology for the quillback rockfish. The concordance of the entire quillback rockfish {sup 14}C record with the yelloweye rockfish time series demonstrated the effectiveness of this age validation technique, confirmed the longevity of the quillback rockfish up to a minimum of 43 years, and strongly supports higher age estimates of up to 90 years.

  18. Atom Wavelike Nature Solved Mathematically

    Science.gov (United States)

    Sven, Charles

    2010-03-01

    Like N/S poles of a magnet the strong force field surrounding, confining the nucleus exerts an equal force [noted by this author] driving electrons away from the attraction of positively charged protons force fields in nucleus -- the mechanics for wavelike nature of electron. Powerful forces corral closely packed protons within atomic nucleus with a force that is at least a million times stronger than proton's electrical attraction that binds electrons. This then accounts for the ease of electron manipulation in that electron is already pushed away by the very strong atomic N/S force field; allowing electrons to drive photons when I strike a match. Ageless atom's electron requirements, used to drive light/photons or atom bomb, without batteries, must be supplied from a huge, external, super high frequency, super-cooled source, undetected by current technology, one that could exist 14+ billion years without degradation -- filling a limitless space prior to Big Bang. Using only replicable physics, I show how our Universe emanated from that event.

    Although progress has been made in the treatment of childhood brain tumors,work remains to understand the complexities of disease, treatment, and contextual factors that underlie individual differences in outcome. A combination of both an idiographic approach (incorporating observations made by adult survivors of childhood brain tumors) and a nomothetic approach (reviewing the literature for brain tumor survivors as well as childhood cancer survivors) is presented. Six areas of concern are reviewed from both an idiographic and nomothetic perspective, including social/emotional adjustment, insurance, neurocognitive late effects, sexuality and relationships, employment, and where survivors accessed information about their disease and treatment and possible late effects. Guidelines to assist health care professionals working with childhood brain tumor survivors are offered with the goal of improving psychosocial and neurocognitive outcomes in this population.

    2011-09-01

    This paper explores how a computer-generated reconstruction of a church can be adapted to create a panoramic film that is presented in a panoramic viewer and also on a wrap-around projection system. It focuses on the fundamental principles of creating 360º films, not only in 3D modelling software, but also presents how to record 360º video using panoramic cameras inside the heritage site. These issues are explored in a case study of Charles Church in Plymouth, UK that was bombed in 1941 and has never been rebuilt. The generation of a 3D model of the bombed church started from the creation of five spherical panoramas and through the use of Autodesk ImageModeler software. The processed files were imported and merged together in Autodesk 3ds Max where a visualisation of the ruin was produced. A number of historical images were found and this collection enabled the process of a virtual reconstruction of the site. The aspect of merging two still or two video panoramas (one from 3D modelling software, the other one recorded on the site) from the same locations or with the same trajectories is also discussed. The prototype of 360º non-linear film tells a narrative of a wartime wedding that occurred in this church. The film was presented on two 360º screens where members of the audience could make decisions on whether to continue the ceremony or whether to run away when the bombing of the church starts. 3D modelling software made this possible to render a number of different alternati ves (360º images and 360º video). Immersive environments empower the visitor to imagine the building before it was destroyed.

    Traumatic events in one's younger years can have an impact on how an individual copes with later life. One traumatic experience for Jewish individuals was the Holocaust. Some of these people are moving into long-term care facilities. It was within this context that the research question emerged: What are Holocaust survivor residents' perceptions of a life lived as they move into a long-term care facility? For this qualitative study, Holocaust survivors were individually interviewed. Findings emphasize that nursing care needs to ensure that Holocaust survivor residents participate in activities, receive timely health care, and receive recognition of their life experiences.

  13. Science and Security before the Atomic Bomb: The Loyalty Case of Harald U. Sverdrup

    Science.gov (United States)

    Oreskes, Naomi; Rainger, Ronald

    In the summer of 1941, Harald Sverdrup, the Norwegian-born Director of the Scripps Institution of Oceanography (SIO) in La Jolla, California, was denied security clearance to work on Navy-sponsored research in underwater acoustics applied to anti-submarine warfare. The clearance denial embarrassed the world renown oceanographer and Arctic explorer, who repeatedly offered his services to the U.S. government only to see scientists of far lesser reputation called upon to aid the war effort. The official story of Sverdrup's denial was the risk of blackmail over relatives in occupied Norway. Declassified documents tell a different story. Although Sverdrup's integrity was defended on the highest levels of U.S. science, doubt was cast upon him by members of his own institution, who accused him of being a Nazi sympathiser. Personal distrust, rooted in scientific and intellectual disagreement, spilled over into questions about Sverdrup's loyalty and judgement. These doubts were considered sufficient grounds for withholding clearance, until Roger Revelle, a former student of Sverdrup now working within the Navy, was able to obtain a limited clearance for Sverdrup to develop techniques to forecast surf conditions during amphibious assaults. After the war, this work was credited with saving many lives, but at the time it placed Sverdrup out of the mainstream of Navy-sponsored oceanographic research. In being denied access to major areas of scientific work, Sverdrup's position as a leader of American oceanography was undermined. The loyalty case of Harald Sverdrup illustrates the emergence of an institutional apparatus through which the U.S. military began to control and shape the organisation of American science in the twentieth century. Military sponsorship of scientific research, begun during the open conflicts of World War II and continuing into the simmering tensions of the Cold War, involved explicit control by the U.S. military of who had access to critical information. This in turn meant who could do science in conjunction with the military. As the U.S. Navy became the principal sponsor of oceanography in the post-war years, clearance to do military work became to a great extent clearance to do oceanography. Choices about who could be trusted were also choices about who would do science, and what kind of science they would do.

  14. Game of thrown bombs in 3D: using high speed cameras and photogrammetry techniques to reconstruct bomb trajectories at Stromboli (Italy)

    Large juvenile bombs and lithic clasts, produced and ejected during explosive volcanic eruptions, follow ballistic trajectories. Of particular interest are: 1) the determination of ejection velocity and launch angle, which give insights into shallow conduit conditions and geometry; 2) particle trajectories, with an eye on trajectory evolution caused by collisions between bombs, as well as the interaction between bombs and ash/gas plumes; and 3) the computation of the final emplacement of bomb-sized clasts, which is important for hazard assessment and risk management. Ground-based imagery from a single camera only allows the reconstruction of bomb trajectories in a plan perpendicular to the line of sight, which may lead to underestimation of bomb velocities and does not allow the directionality of the ejections to be studied. To overcome this limitation, we adapted photogrammetry techniques to reconstruct 3D bomb trajectories from two or three synchronized high-speed video cameras. In particular, we modified existing algorithms to consider the errors that may arise from the very high velocity of the particles and the impossibility of measuring tie points close to the scene. Our method was tested during two field campaigns at Stromboli. In 2014, two high-speed cameras with a 500 Hz frame rate and a ~2 cm resolution were set up ~350m from the crater, 10° apart and synchronized. The experiment was repeated with similar parameters in 2015, but using three high-speed cameras in order to significantly reduce uncertainties and allow their estimation. Trajectory analyses for tens of bombs at various times allowed for the identification of shifts in the mean directivity and dispersal angle of the jets during the explosions. These time evolutions are also visible on the permanent video-camera monitoring system, demonstrating the applicability of our method to all kinds of explosive volcanoes.

    2011-02-21

    In recent years, a phenomenon of "late effects of the Holocaust" has emerged, with impacts on the psychological and physical health of ageing Holocaust survivors. As Holocaust survivors age, they may experience heightened anxiety around normal processes of ageing, worsened post-traumatic stress disorder with cognitive decline, and fear of the medical system. Holocaust survivors are at increased risk of osteoporosis, cardiometabolic disease due to hypothalamic-pituitary-adrenal axis dysfunction, cancer, and sequelae of Nazi medical experiments. From existing medical literature on this topic, practical principles of management are derived to create a framework for sensitive medical management of Holocaust survivors in Australia. The issues discussed are also relevant to the wider geriatric refugee or prisoner-of-war experience.

  16. Bomb-spike dating of a mummified baboon in Ludwig Cave, Namibia

    2007-01-01

    Full Text Available In 1982 a mummified adult female baboon was discovered on a ledge in Ludwig Cave in Namibia. A toe bone was removed for dating in July 1995. AMS radiocarbon dating of bone collagen, tendon, and skin indicates a post-modern age. Application of the atomic bomb-spike calibration curve suggests death in late 1977 and an age at death of around 19 years. Baboons roost in the cave and the mummified female, along with a mummified juvenile male discovered in 2002 and three rotting corpses discovered in 1995, were probably chased by other baboons or by leopards down a ca. 6 m drop during the rainy season, and were unable to climb the steep and very slippery slope to escape. The large number of baboons trapped in the cave in less than 20 years, and mummification of two individuals on dry, dusty ledges in the cave, may explain why large numbers of baboon skeletons have been discovered in ancient bone breccias (up to 4 Ma old in a number of caves throughout Southern Africa.

    Satisfaction with care is important to cancer survivors' health outcomes. Satisfaction with care is not equal for all cancer survivors, and sexual minority (i.e., lesbian, gay, and bisexual) cancer survivors may experience poor satisfaction with care. Data were drawn from the 2010 LIVESTRONG national survey. The final sample included 207 sexual minority cancer survivors and 4,899 heterosexual cancer survivors. Satisfaction with care was compared by sexual orientation, and a Poisson regression model was computed to test the associations between sexual orientation and satisfaction with care, controlling for other relevant variables. Sexual minority cancer survivors had lower satisfaction with care than did heterosexual cancer survivors (B = -0.12, SE = 0.04, Wald χ(2) = 9.25, pSexual minorities experience poorer satisfaction with care compared to heterosexual cancer survivors. Satisfaction with care is especially relevant to cancer survivorship in light of the cancer-related health disparities reported among sexual minority cancer survivors.

    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.

    1997-03-01

    Positive identification of human remains is one of the most important tasks in mass disaster investigations. Religious and jurisdictional demands in Israel, require the identification process to be completed in the shortest possible time. In the 18 suicidal terrorist bombings that took place in Israel between the years 1993-1996, 127 victims and 19 perpetrators were killed, and their severely fragmented bodies were identified within 24 h. The efficient completion of the identification endeavor was enabled by the implementation of a variety of techniques and the close collaboration in the investigation between the different emergency and forensic agencies. This paper presents the mass disaster identification policy and techniques currently used in Israel. The importance of an interdisciplinary approach for the identification of extremely fragmented human remains from mass disasters and the creation of a central data bank of fingerprints and genetic markers is emphasized.

  5. Detecting body cavity bombs with nuclear quadrupole resonance

    Science.gov (United States)

    Collins, Michael London

    Nuclear Quadrupole Resonance (NQR) is a technology with great potential for detecting hidden explosives. Past NQR research has studied the detection of land mines and bombs concealed within luggage and packages. This thesis focuses on an NQR application that has received less attention and little or no publicly available research: detecting body cavity bombs (BCBs). BCBs include explosives that have been ingested, inserted into orifices, or surgically implanted. BCBs present a threat to aviation and secure facilities. They are extremely difficult to detect with the technology currently employed at security checkpoints. To evaluate whether or not NQR can be used to detect BCBs, a computational model is developed to assess how the dielectric properties of biological tissue affect the radio frequency magnetic field employed in NQR (0.5-5MHz). The relative permittivity of some biological tissue is very high (over 1,000 at 1MHz), making it conceivable that there is a significant effect on the electromagnetic field. To study this effect, the low-frequency approximation known as the Darwin model is employed. First, the electromagnetic field of a coil is calculated in free space. Second, a dielectric object or set of objects is introduced, and the free-space electric field is modified to accommodate the dielectric object ensuring that the relevant boundary conditions are obeyed. Finally, the magnetic field associated with the corrected electric field is calculated. This corrected magnetic field is evaluated with an NQR simulation to estimate the impact of dielectric tissue on NQR measurements. The effect of dielectric tissue is shown to be small, thus obviating a potential barrier to BCB detection. The NQR model presented may assist those designing excitation and detection coils for NQR. Some general coil design considerations and strategies are discussed.

    Full Text Available After a bombing attack, patients were brought into hospital suffering from a combination of injuries caused by the blast, penetrating injuries and burns which as a case of polytrauma. In penetrating thoracoabdominal injuries due to bombing possibility of cardiac injury should be kept in mind. Penetrating cardiac injuries in children are rare but has a high mortality and morbidity. In some cases there may be difficulty in diagnosis of penetrating cardiac injury. In this case we want to share the diagnosis, treatment and follow-up processes of penetrating cardiac and hepatic injury with burns of a politrauma child due to bombing.

  11. Survivor care for pediatric cancer survivors: a continuously evolving discipline.

    Record, Elizabeth O; Meacham, Lillian R

    2015-07-01

    This article summarizes recent findings regarding the prevalence of chronic health conditions, cardiovascular and pulmonary late effects, and second malignancies in childhood cancer survivors (CCSs), and examines facilitators and barriers to survivor care. The estimated cumulative prevalence for a serious chronic disease in CCSs is 80% by age 45. The crude prevalence for cardiac conditions is 56.4% and for pulmonary dysfunction is 65.2%. Research in cardio-oncology is focused on better methods of predicting risk for cardiac dysfunction, and better methods of detection and interventions to prevent cardiac late effects. Pulmonary late effects, recognized to be a significant cause of late mortality, were detected by surveillance tests in more than 50% of CCSs but are often subclinical. Rates of subsequent malignant neoplasm continue to increase as the population ages. All of these factors make it clear that life-long surveillance is required and models of care should consider risk for late effects and socioeconomic and patient-specific factors. It is becoming clear that there is no age after which the occurrence of late effects plateaus and surveillance can be reduced. Survivors should be empowered to advocate for their survivor care and options for follow-up should be tailored to their needs.

    In November 2010, during my seventh trip to North Korea, Pyongyang produced a big surprise--it decided to build its own light-water reactor and uranium enrichment plant. During my first visit I was shown plutonium produced in its Yongbyon nuclear complex to convince me they have the bomb. For nearly 40 years, Pyongyang has moved along parallel paths of nuclear energy and nuclear weapons, opting to chose bombs over electricity. I will discuss how North Korea got the bomb, why it got it, and the prospects of whether or not it will give up the bomb. Finally, I will try to show with photos and stories of how North Korea is not such a hermit kingdom after all.

    2016-01-01

    We examined how the Boston Marathon bombings affected threat perception in the Boston community. In a threat perception task, participants attempted to "shoot" armed targets and avoid shooting unarmed targets. Participants viewing images of the bombings accompanied by affectively negative music and text (e.g., "Terror Strikes Boston") made more false alarms (i.e., more errors "shooting" unarmed targets) compared to participants viewing the same images accompanied by affectively positive music and text (e.g., "Boston Strong") and participants who did not view bombing images. This difference appears to be driven by decreased sensitivity (i.e., decreased ability to distinguish guns from non-guns) as opposed to a more liberal bias (i.e., favouring the "shoot" response). Additionally, the more strongly affected the participant was by the bombings, the more their sensitivity was reduced in the negatively framed condition, suggesting that this framing was particularly detrimental to the most vulnerable individuals in the affected community.

    2006-01-01

    Full Text Available The main aim of the study is to examine effects of bombing on development of early maladaptive schemas in children who live in directly bombed towns in comparison with children who live in towns not directly exposed to bombing. The subjects were twelve years old at the moment of testing (February 2005 meaning that they were at the age of seven during the bombing. Additional aim was to examine gender differences in development of early maladaptive schemas. The theory of Young (1990 provided framework for the study. According to the theory, early maladaptive cognitive schemas, which present basis for psychological disorder later in life, begin to develop in childhood in connection with traumatic experiences and/or other aversive circumstances. The results showed that the early maladaptive schemas are more frequent in children from directly exposed towns; and in male subjects comparing with females.

    Full Text Available There has been a dramatic increase in the number of childhood cancer survivors living to an old age due to improved cancer treatments. However, these survivors are at risk of numerous late effects as a result of their cancer therapy. Engaging in protective health behaviors and limiting health damaging behaviors are vitally important for these survivors given their increased risks. We reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings. We examine the prevalence of a variety of health behaviors among childhood cancer survivors, identify significant risk factors, and describe health behavior interventions for survivors.

    The objective of the study is to explore psychosexual functioning and its relationship with quality of life in survivors of cancer in childhood. Sixty childhood cancer survivors completed two questionnaires: psychosexual and social functioning questionnaire and MOS-SF-36. Psychosexual problems were frequent. About 20% of the survivors felt a limitation in their sexual life due to their illness. Older survivors (> or =25 years) had significantly less experience with sexual intercourse than their age-matched peers in the Dutch population (p = 0.010). Survivors treated in adolescence had a delay in achieving psychosexual milestones compared with those treated in childhood: dating (ppsychosexual problems compared with survivors without these problems. In this cohort of childhood cancer survivors, psychosexual problems were frequent. Treatment in adolescence is a risk factor for a delay in psychosexual development. (c) 2007 John Wiley & Sons, Ltd.

    Little, M P

    2003-01-01

    This paper reviews current knowledge on the deterministic and stochastic risks (the latter including the risk of cancer and of hereditary disease) associated with exposure to ionizing radiation. Particular attention is paid to cancer risks following exposure to man-made low linear energy transfer radiation. Excess cancer risks have been observed in the Japanese atomic bomb survivors and in many medically and occupationally exposed groups. In general, the relative risks among Japanese survivors of atomic-bomb explosions are greater than those among comparable subsets in studies of medically exposed individuals. Cell sterilization largely accounts for the discrepancy in relative risks between these two populations, although other factors may contribute, such as the generally higher underlying cancer risks in the medical series than in the Japanese atomic bomb survivors. Risks among occupationally exposed groups such as nuclear workforces and underground miners are generally consistent with those observed in the Japanese atomic bomb survivors.

    The goal of this study is to describe the imaging features of lower extremity blast injuries in patients encountered in the radiology departments from the Boston Marathon bombings. A total of 115 patients presented to four acute care hospitals on April 15, 2013, 43 of whom presented with lower extremity injuries and were included in this study. The imaging findings of primary, secondary, tertiary, and quaternary blast injuries were evaluated. Forty-one of 43 patients sustained secondary blast injuries to the lower extremities with 31 patients (70 %) having retained shrapnel, seven patients (16 %) having soft tissue lacerations without retained shrapnel, and ten patients (23 %) having lower extremity amputation (7 % double amputees). Eight of these patients (20 %) had lower extremity fractures, and five patients (12 %) had vascular injuries. Two of the 43 patients (5 %) had only tertiary injuries, and five of 43 patients (12 %) were noted to have lower extremity burns, consistent with quaternary blast injury. No primary blast injury occurred in the lower extremities. A vast majority of lower extremity injuries were from secondary blast injury, most commonly from retained shrapnel in 70 % of patients and 23 % of patients sustaining lower extremity amputation. Retained shrapnel in the lower extremity was most commonly ball bearings and pressure cooker fragments, and most injuries affected the leg, followed by the thigh and foot.

    and the number of samples for MIA analysis was insufficient for some months. Hence, unequivocal validation of shortfin mako age estimates has yet to be accomplished. Atmospheric testing of thermonuclear devices in the 1950s and 1960s effectively doubled the natural atmospheric radiocarbon ({sup 14}C). The elevated {sup 14}C levels were first recorded in 1957-58, with a peak around 1963. As a consequence, {sup 14}C entered the ocean through gas exchange with the atmosphere at the ocean surface and in terrestrial runoff. Despite variable oceanographic conditions, a worldwide rise of the bomb {sup 14}C signal entered the ocean mixed layer as dissolved inorganic carbon (DIC) in 1957-58. The large amounts of {sup 14}C released from the bomb tests produced a signature that can be followed through time, throughout the marine food web, and into deeper waters. The marked increase of radiocarbon levels was first measured in the DIC of seawater and in biogenic marine carbonates of hermatypic corals in Florida. Subsequently, this record was documented in corals from other regions and in the thallus of rhodoliths. The accumulation of radiocarbon in the hard parts of most marine organisms in the mixed layer (such as fish otoliths and bivalves) was synchronous with the coral time-series. This technique has been used to validate age estimates and longevity of numerous bony fishes to date, as well as to establish bomb radiocarbon chronologies from different oceans. In the first application of this technique to lamnoid sharks, validated annual band-pair deposition in vertebral growth bands for the porbeagle (Lamna nasus) aged up to 26 years. Radiocarbon values from samples obtained from 15 porbeagle caught in the western North Atlantic Ocean (some of which were known-age) produced a chronology similar in magnitude to the reference carbonate chronology for that region. The observed phase shift of about 3 years was attributed to different sources of carbon between vertebrae and those for

In the Boston cohort, 164 of 264 casualties were transported to level 1 trauma centers, and 22 (13.4%) required ophthalmology consultations. In the West cohort, 218 of 263 total casualties were transported to participating centers, of which 14 (6.4%) required ophthalmology consultations. Boston had significantly shorter mean distances to treating facilities (1.6 miles vs. 53.6 miles; P = 0.004). Overall, rigid eye shields were more likely not to have been provided than to have been provided on the scene (PBoston sustained more lower extremity injuries because of the ground-level bomb. Overall, 27.8% of consultations were called from emergency rooms, whereas the rest occurred afterward. Challenges in logistics and communications were identified. Ocular injuries are common and potentially blinding in mass-casualty incidents. Systemic and ocular polytrauma is the rule in terrorism, whereas isolated ocular injuries are more common in other calamities. Key lessons learned included educating the public to stay away from windows during disasters, promoting use of rigid eye shields by first responders, the importance of reliable communications, deepening the ophthalmology call algorithm, the significance of visual incapacitation resulting from loss of spectacles, improving the rate of early detection of ocular injuries in emergency departments, and integrating ophthalmology services into trauma teams as well as maintaining a voice in hospital-wide and community-based disaster planning.

    Purpose Survival rates for individuals diagnosed with retinoblastoma (RB) exceed 95% in the United States; however, little is known about the long-term psychosocial outcomes of these survivors. Patients and Methods Adult RB survivors, diagnosed from 1932 to 1994 and treated in New York, completed a comprehensive questionnaire adapted from the Childhood Cancer Survivor Study (CCSS), by mail or telephone. Psychosocial outcomes included psychological distress, anxiety, depression, somatization, fear of cancer recurrence, satisfaction with facial appearance, post-traumatic growth, and post-traumatic stress symptoms; noncancer CCSS siblings served as a comparison group. Results A total of 470 RB survivors (53.6% with bilateral RB; 52.1% female) and 2,820 CCSS siblings were 43.3 (standard deviation [SD], 11) years and 33.2 (SD, 8.4) years old at the time of study, respectively. After adjusting for sociodemographic factors, RB survivors did not have significantly higher rates of depression, somatization, distress, or anxiety compared with CCSS siblings. Although RB survivors were more likely to report post-traumatic stress symptoms of avoidance and/or hyperarousal (both P < .01), only five (1.1%) of 470 met criteria for post-traumatic stress disorder. Among survivors, having a chronic medical condition did not increase the likelihood of psychological problems. Bilateral RB survivors were more likely than unilateral RB survivors to experience fears of cancer recurrence (P < .01) and worry about their children being diagnosed with RB (P < .01). However, bilateral RB survivors were no more likely to report depression, anxiety, or somatic complaints than unilateral survivors. Conclusion Most RB survivors do not have poorer psychosocial functioning compared with a noncancer sample. In addition, bilateral and unilateral RB survivors seem similar with respect to their psychological symptoms. PMID:26417002

    This paper describes an interactive multimedia simulator for air transportation bomb threat training. The objective of this project is to improve the air transportation sector s capability to respond to bomb threats received by commercial airports and aircraft. The simulator provides realistic training on receiving and responding to a variety of bomb threats that might not otherwise be possible due to time, cost, or operational constraints. Validation analysis indicates that the use of the simulator resulted in statistically significant increases in individual ability to respond to these types of bomb threats.

    From 1986-9, the Kurdish population of Iraqi Kurdistan was subjected to an intense campaign of military action, and genocide by the central Iraq government. This campaign, referred to as the Anfal, included systematic attacks consisting of aerial bombings, mass deportation, imprisonment, torture, and chemical warfare. It has been estimated that around 200,000 Kurdish people disappeared. To gain a better understanding of current priority mental health and psychosocial problems among Kurdish survivors of the Anfal, and to inform the subsequent design of culturally appropriate and relevant assessment instruments and services to address these problems. The study examined 1) the nature and cause of current problems of survivors of torture and/or civilian attacks and their families, 2) what survivors do to address these problems, and 3) what they felt should be done. We used a grounded theory approach. Free list interviews with a convenience sample (n=42) explored the current problems of Kurdish persons affected by torture. Subsequent key informant interviews (n=21) gathered more detailed information on the priority mental health problem areas identified in the free list interviews. Major mental health problem areas emerging from the free list interviews (and explored in the key informant interviews) included 1) problems directly related to the torture, 2) problems related to the current situation, and 3) problems related to the perception and treatment by others in the community. Problems were similar, but not identical, to Western concepts of depression, anxiety, PTSD and related trauma, and traumatic grief. Iraqi Kurdish torture survivors in Iraq have many mental health and psychosocial problems found among torture survivors elsewhere. The findings suggest that the problems are a result of the trauma experienced as well as current stressors. Development of mental health assessment tools and interventions should therefore address both previous trauma and current

    Objective We discuss the strengths of the medical response to the Boston Marathon bombings that led to the excellent outcomes. Potential shortcomings were recognized, and lessons learned will provide a foundation for further improvements applicable to all institutions. Background Multiple casualty incidents from natural or man-made incidents remain a constant global threat. Adequate preparation and the appropriate alignment of resources with immediate needs remain the key to optimal outcomes. Methods A collaborative effort among Boston’s trauma centers (2 level I adult, 3 combined level I adult/pediatric, 1 freestanding level I pediatric) examined the details and outcomes of the initial response. Each center entered its respective data into a central database (REDCap), and the data were analyzed to determine various prehospital and early in-hospital clinical and logistical parameters that collectively define the citywide medical response to the terrorist attack. Results A total of 281 people were injured, and 127 patients received care at the participating trauma centers on that day. There were 3 (1%) immediate fatalities at the scene and no in-hospital mortality. A majority of the patients admitted (66.6%) suffered lower extremity soft tissue and bony injuries, and 31 had evidence for exsanguinating hemorrhage, with field tourniquets in place in 26 patients. Of the 75 patients admitted, 54 underwent urgent surgical intervention and 12 (22%) underwent amputation of a lower extremity. Conclusions Adequate preparation, rapid logistical response, short transport times, immediate access to operating rooms, methodical multidisciplinary care delivery, and good fortune contributed to excellent outcomes.

  14. Mechanism of Formation of Volcanic Bombs and Achneliths: Insights From Anisotropy of Magnetic Susceptibility Measurements.

    Canon-Tapia, E.

    2016-12-01

    Volcanic bombs and achneliths are a special type of pyroclastic fragments formed by mildly explosive volcanic eruptions. The common explanation for the general shapes of these types of particles is that they are the result of the rush of air acting on a fluid clot during flight. A competing, less commonly quoted model, envisages the shapes of volcanic bombs as the result of forces acting at the moment of ejection of liquid from the magma pool in the conduit, experiencing an almost negligible modification through its travel on the air. Quantitative evidence supporting either of those two models is limited, or might not be directly applicable to all morphological types. In this work, anisotropy of magnetic susceptibility (AMS) is used as a source of information that provides clues concerning the mechanism of formation of volcanic bombs and achneliths in general. AMS results indicate a fundamental difference between two of the most common morphological bomb types, and are used to constraint mechanisms of formation. It is shown that neither of the two most common mechanisms of formation of volcanic bombs seems acceptable on its current form. An alternative, two-step process is therefore outlined. The first step involves ejection of a small volume of magma dragged on top of large bubbles of gas that reach the surface of a magma pool. The second stage involves the disruption of the ejected magma either as the result of the bursting of the gas bubble, or as a consequence of currents of air that further destabilize already formed jets of liquid. This destabilization is not equivalent to the aerodynamic deformation invoked in current models. Finally, the evidence presented by the anisotropy of magnetic susceptibility indicates that some types of volcanic bombs are likely to preserve the initial deformation, whereas some others might loose it completely.

  15. Atom Skimmers and Atom Lasers Utilizing Them

    Atom skimmers are devices that act as low-pass velocity filters for atoms in thermal atomic beams. An atom skimmer operating in conjunction with a suitable thermal atomic-beam source (e.g., an oven in which cesium is heated) can serve as a source of slow atoms for a magneto-optical trap or other apparatus in an atomic-physics experiment. Phenomena that are studied in such apparatuses include Bose-Einstein condensation of atomic gases, spectra of trapped atoms, and collisions of slowly moving atoms. An atom skimmer includes a curved, low-thermal-conduction tube that leads from the outlet of a thermal atomic-beam source to the inlet of a magneto-optical trap or other device in which the selected low-velocity atoms are to be used. Permanent rare-earth magnets are placed around the tube in a yoke of high-magnetic-permeability material to establish a quadrupole or octupole magnetic field leading from the source to the trap. The atoms are attracted to the locus of minimum magnetic-field intensity in the middle of the tube, and the gradient of the magnetic field provides centripetal force that guides the atoms around the curve along the axis of the tube. The threshold velocity for guiding is dictated by the gradient of the magnetic field and the radius of curvature of the tube. Atoms moving at lesser velocities are successfully guided; faster atoms strike the tube wall and are lost from the beam.

    The 11-M Madrid commuter train bombings of 2004 constituted the second biggest terrorist attack to occur in Europe after Lockerbie, while the subsequent investigation became the most complex and wide-ranging forensic case in Spain. Standard short tandem repeat (STR) profiling of 600 exhibits left certain key incriminatory samples unmatched to any of the apprehended suspects. A judicial order to perform analyses of unmatched samples to differentiate European and North African ancestry became a critical part of the investigation and was instigated to help refine the search for further suspects. Although mitochondrial DNA (mtDNA) and Y-chromosome markers routinely demonstrate informative geographic differentiation, the populations compared in this analysis were known to show a proportion of shared mtDNA and Y haplotypes as a result of recent gene-flow across the western Mediterranean, while any two loci can be unrepresentative of the ancestry of an individual as a whole. We based our principal analysis on a validated 34plex autosomal ancestry-informative-marker single nucleotide polymorphism (AIM-SNP) assay to make an assignment of ancestry for DNA from seven unmatched case samples including a handprint from a bag containing undetonated explosives together with personal items recovered from various locations in Madrid associated with the suspects. To assess marker informativeness before genotyping, we predicted the probable classification success for the 34plex assay with standard error estimators for a naïve Bayesian classifier using Moroccan and Spanish training sets (each n = 48). Once misclassification error was found to be sufficiently low, genotyping yielded seven near-complete profiles (33 of 34 AIM-SNPs) that in four cases gave probabilities providing a clear assignment of ancestry. One of the suspects predicted to be North African by AIM-SNP analysis of DNA from a toothbrush was identified late in the investigation as Algerian in origin. The results

    Full Text Available In 1955, the U.S. Information Service (USIS Tokyo produced a thirty-minute documentary film Blessing of Atomic Energy in commemoration of the tenth anniversary of the Atomic bombing of Hiroshima and Nagasaki. The film introduced how the Japanese government, researchers, and companies were using radioisotopes offered by the U.S. Argonne National Laboratory for the “peaceful” purposes in agriculture, medicine, hygiene, industry, and disaster prevention. The film also showed the mechanism of atomic power generation, and explained that it was already put into practice in the U.S. and Europe. The images of Japanese people enjoying the “blessing” of the “peaceful” use of atomic energy, ten years after the traumatic experience of A-bombs, were not only shown all over Japan, but also translated into different languages and shown in many countries, including the UK, Finland, Indonesia, Sudan, and Venezuela. The film was part of some fifty educational and documentary films produced for President Eisenhower’s “Atoms for Peace” campaign – a global information dissemination programs on the U.S. leadership in the civilian use of nuclear energy. This paper will explore the roles USIS films played in disseminating information on the “peaceful” use of nuclear energy in the early Cold War era.

    Suicide bereavement is frequently related to clinically significant psychological distress and affected by stigma. This study was designed to evaluate the relationship between psychological distress by psychopathological domains and stigma, in a sample of individuals bereaved by suicide (suicide survivors). The data were collected between January 2012 and December 2014 and included information on sociodemographic variables (gender, age, marital status and education level) and responses to the Stigma of Suicide Survivor scale (STOSSS) and the Brief Symptom Inventory (BSI). One hundred and fifty-five suicide survivors completed the evaluation and were included in the study. Levels of psychological distress in suicide survivors, as measured by BSI, were positively related to levels of perceived stigma toward suicide survivors, as measured by STOSSS. The association was not affected by age and gender, or by marital status, education level, days from suicide or a personal history of suicide attempt. Participants with higher scores on almost all subscales of the BSI, particularly the interpersonal sensitivity and paranoid ideation subscales, reported the highest levels of perceived stigma toward suicide survivors. Levels of distress in subjects bereaved by the suicide of a relative or friend were positively associated with levels of perceived stigma toward suicide survivors. Specific interventions dedicated to the bereavement of suicide survivors might help to alleviate not only psychological distress but also stigma towards loss by suicide.

    Full Text Available Background: The GRPR-antagonist-based radioligands [67/68Ga/111In/177Lu]NeoBOMB1 have shown excellent theragnostic profiles in preclinical prostate cancer models, while [68Ga]NeoBOMB1 effectively visualized prostate cancer lesions in patients. We were further interested to explore the theragnostic potential of NeoBOMB1 in GRPR-positive mammary carcinoma, by first studying [67Ga]NeoBOMB1 in breast cancer models; Methods: We investigated the profile of [67Ga]NeoBOMB1, a [68Ga]NeoBOMB1 surrogate, in GRPR-expressing T-47D cells and animal models; Results: NeoBOMB1 (IC50s of 2.2 ± 0.2 nM and [natGa]NeoBOMB1 (IC50s of 2.5 ± 0.2 nM exhibited high affinity for the GRPR. At 37 °C [67Ga]NeoBOMB1 strongly bound to the T-47D cell-membrane (45.8 ± 0.4% at 2 h, internalizing poorly, as was expected for a radioantagonist. [67Ga]NeoBOMB1 was detected >90% intact in peripheral mouse blood at 30 min pi. In mice bearing T-47D xenografts, [67Ga]NeoBOMB1 specifically localized in the tumor (8.68 ± 2.9% ID/g vs. 0.6 ± 0.1% ID/g during GRPR-blockade at 4 h pi. The unfavorably high pancreatic uptake could be considerably reduced (206.29 ± 17.35% ID/g to 42.46 ± 1.31% ID/g at 4 h pi by increasing the NeoBOMB1 dose from 10 pmol to 200 pmol, whereas tumor uptake remained unaffected. Notably, tumor values did not decline from 1 to 24 h pi; Conclusions: [67Ga]NeoBOMB1 can successfully target GRPR-positive breast cancer in animals with excellent prospects for clinical translation.

    Adult childhood cancer survivors report high levels of unemployment, although it is unknown whether this is because of health or employability limitations. We examined 2 employment outcomes from 2003 in the Childhood Cancer Survivor Study (CCSS): (1) health-related unemployment and (2) unemployed but seeking work. We compared survivors with a nearest-age CCSS sibling cohort and examined demographic and treatment-related risk groups for each outcome. We studied 6339 survivors and 1967 siblings ≥25 years of age excluding those unemployed by choice. Multivariable generalized linear models evaluated whether survivors were more likely to be unemployed than siblings and whether certain survivors were at a higher risk for unemployment. Survivors (10.4%) reported health-related unemployment more often than siblings (1.8%; Relative Risk [RR], 6.07; 95% Confidence Interval [CI], 4.32-8.53). Survivors (5.7%) were more likely to report being unemployed but seeking work than siblings (2.7%; RR, 1.90; 95% CI, 1.43-2.54). Health-related unemployment was more common in female survivors than males (Odds Ratio [OR], 1.73; 95% CI, 1.43-2.08). Cranial radiotherapy doses ≥25 Gy were associated with higher odds of unemployment (health-related: OR, 3.47; 95% CI, 2.54-4.74; seeking work: OR, 1.77; 95% CI, 1.15-2.71). Unemployed survivors reported higher levels of poor physical functioning than employed survivors, and had lower education and income and were more likely to be publicly insured than unemployed siblings. Childhood cancer survivors have higher levels of unemployment because of health or being between jobs. High-risk survivors may need vocational assistance.

    2016-01-01

    Potential terror events such as "dirty bombs" could have significant public health effects, but little is known about how low-literacy populations perceive dirty bombs, their trust in public health or government officials to provide credible information, and their willingness to comply with recommended actions. We surveyed 50 low-literacy adults from a large urban center; they were mostly members of ethnic minority groups. We used unique social marketing methods-perceptual mapping and vector message modeling-to create 3-dimensional models that reflected respondents' knowledge of what a dirty bomb is, their intended behaviors should one occur, and their concerns about complying with "shelter in place" recommendations. To further understand individual variations in this at-risk group, a k-means cluster analysis was used to identify 3 distinct segments, differing on trust of local authorities and their emergency response, willingness to comply with emergency directives, and trust of information sources. Message strategies targeting each segment were developed to focus on concepts important to moving the groups toward a "shelter in place" behavior, revealing key differences in how best to communicate with risk communication. We discuss how these methods helped elucidate specific differences in each segment's understanding of and likely response during the event of a "dirty bomb" and how these techniques can be used to create more effective message strategies targeted to these groups.

    Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age. A sex-matched and age-matched population-based control cohort was used for comparison (n=45,449). Demographic and socioeconomic data were obtained from national registers and explored by discrete-time Cox regression analyses. Childhood cancer survivors had a reduced rate of cohabitation [rate ratio (RR) 0.78; 95% confidence interval (CI): 0.73-0.83], owing to lower rates among survivors of both noncentral nervous system (CNS) tumors (RR 0.88; 95% CI: 0.83-0.95) and CNS tumors (RR 0.52; 95% CI: 0.45-0.59). Male CNS tumor survivors had a nonsignificantly lower rate (RR 0.47; 95% CI: 0.38-0.58) than females (RR 0.56; 95% CI: 0.47-0.68). The rates of separation were almost identical to those of controls. In conclusion, the rate of cohabitation was lower for all childhood cancer survivors than for the population-based controls, with the most pronounced reduction among survivors of CNS tumors. Mental deficits after cranial irradiation are likely to be the major risk factor.

  4. Future use of tritium in mapping pre-bomb groundwater volumes.

    The tritium input to groundwater, represented as volume-weighted mean tritium concentrations in precipitation, has been close to constant in Tucson and Albuquerque since 1992, and the decrease in tritium concentrations at the tail end of the bomb tritium pulse has ceased. To determine the future usefulness of tritium measurements in southwestern North America, volume-weighted mean tritium levels in seasonal aggregate precipitation samples have been gathered from 26 sites. The averages range from 2 to 9 tritium units (TU). Tritium concentrations increase with site latitude, and possibly with distance from the coast and with site altitude, reflecting local ratios of combination of low-tritium moisture advected from the oceans with high-tritium moisture originating near the tropopause. Tritium used alone as a tool for mapping aquifer volumes containing only pre-bomb recharge to groundwater will become ambiguous when the tritium in precipitation at the end of the bomb tritium pulse decays to levels close to the analytical detection limit. At such a time, tritium in precipitation from the last one to two decades of the bomb pulse will become indistinguishable from pre-bomb recharge. The threshold of ambiguity has already arrived in coastal areas with a mean of 2 TU in precipitation and will follow in the next three decades throughout the study region. Where the mean tritium level is near 5 TU, the threshold will occur between 2025 and 2030, given a detection limit of 0.6 TU. Similar thresholds of ambiguity, with different local timing possible, apply globally. © 2011, The Author(s). Ground Water © 2011, National Ground Water Association.

    We compared the impact of media vs. direct exposure on acute stress response to collective trauma. We conducted an Internet-based survey following the Boston Marathon bombings between April 29 and May 13, 2013, with representative samples of residents from Boston (n = 846), New York City (n = 941), and the remainder of the United States (n = 2,888). Acute stress symptom scores were comparable in Boston and New York [regression coefficient (b) = 0.43; SE = 1.42; 95% confidence interval (CI), -2.36, 3.23], but lower nationwide when compared with Boston (b = -2.21; SE = 1.07; 95% CI, -4.31, -0.12). Adjusting for prebombing mental health (collected prospectively), demographics, and prior collective stress exposure, six or more daily hours of bombing-related media exposure in the week after the bombings was associated with higher acute stress than direct exposure to the bombings (continuous acute stress symptom total: media exposure b = 15.61 vs. direct exposure b = 5.69). Controlling for prospectively collected prebombing television-watching habits did not change the findings. In adjusted models, direct exposure to the 9/11 terrorist attacks and the Sandy Hook School shootings were both significantly associated with bombing-related acute stress; Superstorm Sandy exposure wasn't. Prior exposure to similar and/or violent events may render some individuals vulnerable to the negative effects of collective traumas. Repeatedly engaging with trauma-related media content for several hours daily shortly after collective trauma may prolong acute stress experiences and promote substantial stress-related symptomatology. Mass media may become a conduit that spreads negative consequences of community trauma beyond directly affected communities.

    We propose a methodology for estimating the residence time of groundwater based on bomb-produced (36)Cl. Water samples were collected from 28 springs and 2 flowing wells located around Mt. Fuji, Central Japan. (36)Cl/Cl ratios in the water samples, determined by accelerator mass spectrometry (AMS), were between 43 × 10(-15) and 412 × 10(-15). A reference time series of the above-background (i.e., bomb-derived) (36)Cl concentration was constructed by linearly scaling the background-corrected Dye-3 data according to the estimated total bomb-produced (36)Cl fallout in the Mt. Fuji area. Assuming piston flow transport, estimates of residence time were obtained by comparing the measured bomb-derived (36)Cl concentrations in spring water with the reference curve. The distribution of (36)Cl-based residence times is basically consistent with that of tritium-based estimates calculated from data presented in previous studies, although the estimated residence times differ between the two tracers. This discrepancy may reflect chlorine recycling via vegetation or the relatively small change in fallout rate, approximately since 1975, which would give rise to large uncertainties in (36)Cl-based estimates of recharge for the period, approximately since 1975. Given the estimated ages for groundwater from flowing wells, dating based on a (36)Cl bomb pulse may be more reliable and sensitive for groundwater recharged before 1975, back as far as the mid-1950s. © 2011, The Author(s).

  8. Heisenberg in the atomic age science and the public sphere

    CERN Document Server

    Carson, Cathryn

    2010-01-01

    The end of the Second World War opened a new era for science in public life. Heisenberg in the Atomic Age explores the transformations of science's public presence in the postwar Federal Republic of Germany. It shows how Heisenberg's philosophical commentaries, circulating in the mass media, secured his role as science's public philosopher, and it reflects on his policy engagements and public political stands, which helped redefine the relationship between science and the state. With deep archival grounding, the book tracks Heisenberg's interactions with intellectuals from Heidegger to Habermas and political leaders from Adenauer to Brandt. It also traces his evolving statements about his wartime research on nuclear fission for the National Socialist regime. Working between the history of science and German history, the book's central theme is the place of scientific rationality in public life - after the atomic bomb, in the wake of the Third Reich.

    Full Text Available In recent years, contingent and survivor workers have emerged as a common reality in business activities. Unfortunately, contingent worker has high job insecurity on his employment status. On the other side, downsizing activities can result in decreasing job security of survivor worker. As a consequence, both contingent and survivor workers very potential have low organizational commitment. However, organizations still have an opportunity to give their workers an exclusive treatment for building organizational commitment without ignoring the fact that workers have other commitment foci.

    We demonstrate the feasibility of controlling an atomic scale mechanical device by an external electrical signal. On a germanium substrate, a switching motion of pairs of atoms is induced by electrons that are directly injected into the atoms with a scanning tunneling microscope tip. By precisely controlling the tip current and distance we make two atom pairs behave like the flippers of an atomic-sized pinball machine. This atomic scale mechanical device exhibits six different configurations.

Of the 724 proteins identified at a global false discovery rate of 1%, quantitative information was available for 499. In early-phase ARDS, proteins more abundant in survivors mapped to ontologies indicating a coordinated compensatory response to injury and stress. These included coagulation and fibrinolysis; immune system activation; and cation and iron homeostasis. Proteins more abundant in early-phase non-survivors participate in carbohydrate catabolism and collagen synthesis, with no activation of compensatory responses. The compensatory immune activation and ion homeostatic response seen in early-phase survivors transitioned to cell migration and actin filament based processes in late-phase survivors, revealing dynamic changes in the BALF proteome as the lung heals. Early phase proteins differentiating survivors from non-survivors are candidate biomarkers for predicting survival in ARDS.

    Female survivors of childhood cancer treated with abdominal radiotherapy who manage to conceive are at risk of delivering premature and low-birthweight offspring, but little is known about whether abdominal radiotherapy may also be associated with additional complications during pregnancy and labor. We investigated the risk of developing pregnancy and labor complications among female survivors of childhood cancer in the British Childhood Cancer Survivor Study (BCCSS). Pregnancy and labor complications were identified by linking the BCCSS cohort (n = 17 980) to the Hospital Episode Statistics (HES) for England. Relative risks (RRs) of pregnancy and labor complications were calculated by site of radiotherapy treatment (none/abdominal/cranial/other) and other cancer-related factors using log-binomial regression. All statistical tests were two-sided. A total of 2783 singleton pregnancies among 1712 female survivors of childhood cancer were identified in HES. Wilms tumor survivors treated with abdominal radiotherapy were at threefold risk of hypertension complicating pregnancy (relative risk = 3.29, 95% confidence interval [CI] = 2.29 to 4.71), while all survivors treated with abdominal radiotherapy were at risk of gestational diabetes mellitus (RR = 3.35, 95% CI = 1.41 to 7.93) and anemia complicating pregnancy (RR = 2.10, 95% CI = 1.27 to 3.46) compared with survivors treated without radiotherapy. Survivors treated without radiotherapy had similar risks of pregnancy and labor complications as the general population, except survivors were more likely to opt for an elective cesarean section (RR = 1.39, 95% CI = 1.16 to 1.70). Treatment with abdominal radiotherapy increases the risk of developing hypertension complicating pregnancy in Wilms tumor survivors, and diabetes mellitus and anemia complicating pregnancy in all survivors. These patients may require extra vigilance during pregnancy.

  7. Cigarette smoking in Serbia. Impact of the 78-day NATO bombing campaign.

    2008-01-01

    To estimate short-term and long-term influence of protracted stress caused by the NATO bombing of Serbia on self-reported cigarette smoking, we performed and analyzed smoking survey data. The survey included 320 adult citizens from Sombor, Novi Sad, and Belgrade, three cities that were bombed during the NATO campaign along with other Serbian target cities. We queried participants about their smoking habits before, during, and 8 years after the military intervention. We recorded smoking prevalence rates, intentions to stop smoking, and the age at which smoking began. We also recorded smoking history and cessation attempts. Prior to bombing, 48% of the women and 63% of the men were smokers. During the bombing period, smoking prevalence in male smokers increased significantly. During this period, 32% of the women and 36% of the men increased their smoking by as much as two packs of cigarettes per week. A month after the bombing, the rate of consumption returned to the prewar levels. At present, 44% of the women, and 59% of the men smoke. The average age of current smokers is 43 years (standard deviation /SD/, 14.4) for women and 45 (SD, 16.3) years for men. Female smokers expressed greater interest in quitting smoking than their male counterparts, and they were slightly more successful than men at maintaining abstinence (20 vs. 18%). The participants in our study acknowledged that a compounding factor for successful abstinence was information on depleted uranium (DU) and other pollutants introduced into the environment by the war. Prolonged stress imposed by war causes a short-term increase in smoking prevalence in male smokers and higher cigarette consumption both in male and female smokers. Even though these increases dissipated after the war was over, the prevalence of smoking within the population of urban Serbia remains very high. Counseling and pharmacological support for abstinence relapse in Serbia ere insufficient to sustain smoking cessation during the 8

    Full Text Available Introduction. Injuries caused by aircraft bombs cause severe damages to the human body. They are characterized by massive destruction of injured tissues and organs, primary contamination by polymorph bacterial flora and modified reactivity of the body. Upon being wounded by aircraft bombs projectiles a victim simultaneously sustains severe damages of many organs and organ systems due to the fact that a large number of projectiles at the same time injure the chest, stomach, head and extremities. Case report. We presented a patient, 41 years of age, injured by aircraft bomb with hemo-pneumothorax and destruction of the bone and soft tissue structures of the foot, as well as the treatment result of such heavy injuries. After receiving thoracocentesis and short reanimation, the patient underwent surgical procedure. The team performed thoracotomy, primary treatment of the wound and atypical resection of the left lung. Thoracic drains were placed. The wounds on the lower leg and feet were treated primarily. Due to massive destruction of bone tissue of the right foot by cluster bomb splinters, and impossibility of reconstruction of the foot, guillotine amputation of the right lower leg was performed. Twelve days after the wounding caused by cluster bomb splinters, soft tissue of the left lower leg was covered by Tirsch free transplantant and the defect in the area of the left foot was covered by dorsalis pedis flap. The transplant and flap were accepted and the donor sites were epithelized. Twenty-six days following the wounding reamputation was performed and amputation stump of the right lower leg was closed. The patient was given a lower leg prosthesis with which he could move. Conclusion. Upon being wounded by aircraft bomb splinters, the injured person sustains severe wounds of multiple organs and organ systems due to simultaneous injuries caused by a large number of projectiles. It is necessary to take care of the vital organs first because they

    Full Text Available The majority of childhood cancer survivors and their families will be psychologically healthy, but may desire and benefit from preventive care. A significant portion of the survivor population will be psychosocially distressed in various aspects by their harsh experience of long cancer treatment, and may warrant professional intervention and treatment. Pediatricians should be aware of the late psychological effects that can occur a year or 2 after treatment, possibly in many aspects of a survivor's life. Not only the cancer diagnosis, but also treatments such as chemotherapy, irradiation, and surgical intervention may exert different long-term effects on the psychosocial outcomes of survivors. Pediatricians need to be more concerned with maintaining and improving the psychological health of this growing number of childhood cancer survivors through long-term follow-up clinics, community support, or self-help groups. Research on all of the psychosocial aspects of childhood cancer survivors is important to recognize the reality and problems they face in Korea.

    Background Available data suggest that childhood cancer survivors (CCSs) are comparable to the general population on many lifestyle parameters. However, little is known about minority CCSs. This cross-sectional study describes and compares the body mass index (BMI) and health behaviors of African-American, Hispanic and White survivors to each other and to non-cancer controls. Methods Participants included 452 adult CCS (150 African-American, 152 Hispanic, 150 white) recruited through four childhood cancer treating institutions and 375 ethnically-matched non-cancer controls (125 in each racial/ethnic group) recruited via targeted digit dial. All participants completed a 2-hour in-person interview. Results Survivors and non-cancer controls reported similar health behaviors. Within survivors, smoking and physical activity were similar across racial/ethnic groups. African-American and Hispanic survivors reported lower daily alcohol use than whites, but consumed unhealthy diets and were more likely to be obese. Conclusions This unique study highlights that many minority CCSs exhibit lifestyle profiles that contribute to increased risk for chronic diseases and late effects. Recommendations for behavior changes must consider the social and cultural context in which minority survivors may live. PMID:25564774

    Full Text Available Ann C Mertens, Jordan Gilleland Marchak Aflac Cancer and Blood Disorder Center, Department of Pediatrics, Emory University School of Medicine, Atlanta, GA, USA Abstract: Due to the successful treatment of children with cancer, overall 5-year survival rates now exceed 80%. Because of this success in treating childhood cancer, concerns are now focusing on the potential risk of both physical and psychosocial late effects in these cancer survivors. There is limited data available for clinicians and researchers on the mental health of adolescent survivors of childhood cancers. The goal of this review is to provide a concise evaluation of the content and attributes of literature available on this often overlooked, yet vulnerable, population. Overall, studies on psychological outcomes in adolescent survivors of pediatric cancer suggest that the majority are mentally healthy and do not report significant levels of psychological distress. Several factors were recognized as playing an important role in adverse psychosocial outcomes in these adolescent cancer survivors: to include the diagnosis of a tumor in the central nervous system, central nervous system-directed cancer treatment, and physical late effects. To identify the subset of survivors who may benefit from systematic psychological services, systematic psychological screening of all adolescent cancer survivors during follow-up oncology visits is recommended. Further research into this critical area is needed to help identify other potential risk factors and guide the development of evidence-based support for these vulnerable adolescents.

    The current study aims to determine whether elderly Holocaust survivors are affected differently from non-survivors by the adversity of aging and cancer. Holocaust survivors and non-survivors suffering from cancer, were assessed tapping PTSD, psychiatric symptomatology, psychosocial adjustment to illness and coping with the aftermath of the Holocaust. Findings indicate a significant difference between survivors and non-survivors in post-traumatic symptoms and their intensity, survivors endorsing significantly more PTSD symptoms. Survivors were classified into 3 sub-groups, namely "Victims," "Fighters," and "Those who made it". "Victims" reported the highest percentage of persons who met PTSD, psychiatric symptomatology and difficulty coping with the problems of old age. The diversity of responses points to heterogeneity of long-term adaptation and adjustment among Holocaust survivors and similar response to subsequent adversity.

  13. Case Study: Iran, Islam, the NPT, and the Bomb

    The goals of this case study are: (1) To examine the correlation between Iran's nuclear program and clerical statements; (2) To evaluate the importance of these statements; (3) To understand the relationship between policy and fatwas (Islamic decrees); (4) To address the issue of a 'nuclear fatwa'; and (5) To examine how, if at all, Sharia (Islamic law) has influenced Iran's actions or inactions with respect to the Non-Proliferation Treaty (NPT), the International Atomic Energy Agency (IAEA), and Iran's adherence to its IAEA Safeguards Agreements and the Additional Protocol. The Islamic Republic of Iran (hereinafter Iran) is one of two theocracies in the world, the second being Vatican City. Iran's government derives its constitutional, moral, and political legitimacy from Islam. As a result of this theocratic culture, rules are set and interpreted with a much different calibrator than that of the Western world. Islam affects all aspects of Iranian life. This is further complicated by the fact that Islam is not a nationalistic faith, in that many people all over the world believe in and adhere to Islamic principles. As a result, a political system that derives much of its fervor from being nationalistic is caught between two worlds, one within the land boundaries of Iran and the other within a faith that transcends boundaries. Thus, any understanding of Islamic law must first be understood within this delicate balance of nationalism and transcendence. Iran has found itself on the international stage concerning its nuclear program. Because Iran is a theocratic state, it is imperative to examine its political moves, speeches, rights, and obligations through the lens of Islam. This study will examine how Islam plays a role in Iran's dealing with the International Atomic Energy Agency (IAEA), its understanding of the Nuclear Non-Proliferation Treaty (NPT), including parties obligations under Safeguards Agreements and the Additional

  15. World War II Aerial Bombings of Germany: Fear as Subject of National Socialist Governmental Practices

    Directory of Open Access Journals (Sweden)

    Torben Möbius

    2016-01-01

    Full Text Available This paper highlights how the National Socialist regime in Germany created the so-called «Selbstschutz» («self protection» in civil air defense as an «apparatus of society» (Michel Foucault to educate the German population with regard to the new possibility of aerial bombing. Mechanisms, functions of emotional control and their relationship to concrete practices of the people involved are shown alongside a local example. Regarding the spread and development of fears, this article maintains that practices of «Selbstschutz» had to bridge the temporal gap between future expectations and actual experiences in crucial ways. Before the war, «Selbstschutz» followed its own logic of expectation of danger and risk, as exemplified in aerial-defense simulation exercises, which clashed with the reality of bombs falling on German cities later on.

    Full Text Available We study the problem of decoding secret messages encrypted by the German Army with the M3 Enigma machine after September 15, 1938. We focused our attention on the algorithmization and programming of this problem. A completion and optimization of Zygalski’s sheets method were presented previously. We describe below the missing algorithm solving the problem of the plugboard settings with an algebraic justification. This method is the original idea of the authors, and we can use it for cryptanalysis together with both Zygalski’s sheets method and Rejewski’s bomb method. Next, we present a reconstruction of the cryptologic bomb. We enclose an implementation of both algorithms in Cpp language.

    This article examines the online circulation of a photograph of the immediate aftermath of the 2013 Boston Marathon bombings taken by David Green, a Boston Marathon runner. The photograph fortuitously captured an image of Dzhokhar Tsarnaev, the younger Tsarnaev brother, running from the scene. Initially, Tsarnaev went unnoticed by online message board users and FBI investigators – he was just another face in the urban crowd. However, after he was identified as suspect two, he emerged in the p...

  19. Increased pediatric functional neurological symptom disorders after the Boston marathon bombings: a case series.

    Functional neurological symptom disorders are frequently the basis for acute neurological consultation. In children, they are often precipitated by high-frequency everyday stressors. The extent to which a severe traumatic experience may also precipitate functional neurological abnormalities is unknown. For the 2-week period after the Boston Marathon bombings, we prospectively collected data on patients whose presentation suggested a functional neurological symptom disorder. We assessed clinical and demographic variables, duration of symptoms, extent of educational impact, and degree of connection to the Marathon bombing. We contacted all patients at 6 months after presentation to determine the outcome and accuracy of the diagnosis. In a parallel study, we reported a baseline of 2.6 functional neurological presentations per week in our emergency room. In the week after the Marathon bombings, this frequency tripled. Ninety-one percent of presentations were delayed by 1 week, with onset around the first school day after a city-wide lockdown. Seventy-three percent had a history of a prior psychiatric diagnosis. At the 6 months follow-up, no functional neurological symptom disorder diagnoses were overturned and no new organic diagnosis was made. Pediatric functional neurological symptom disorder may be precipitated by both casual and high-intensity stressors. The 3.4-fold increase in incidence after the Boston Marathon bombings and city-wide lockdown demonstrates the marked effect that a community-wide tragedy can have on the mental health of children. Care providers must be aware of functional neurological symptom disorders after stressful community events in vulnerable patient populations, particularly those with prior psychiatric diagnoses.

    To identify risk factors for adverse psychological outcomes among adult siblings of long-term survivors of childhood cancer. Cross-sectional, self-report data from 3083 adult siblings (mean age 29 years, range 18-56 years) of 5 + year survivors of childhood cancer were analyzed to assess psychological outcomes as measured by the Brief Symptom Inventory-18 (BSI-18). Sociodemographic and health data, reported by both the siblings and their matched cancer survivors, were explored as risk factors for adverse sibling psychological outcomes through multivariable logistic regression. Self-reported symptoms of psychological distress, as measured by the global severity index of the BSI-18, were reported by 3.8% of the sibling sample. Less than 1.5% of siblings reported elevated scores on two or more of the subscales of the BSI-18. Risk factors for sibling depression included having a survivor brother (OR 2.22, 95% CI 1.42-3.55), and having a survivor with impaired general health (OR 2.15, 95% CI 1.18-3.78). Siblings who were younger than the survivor reported increased global psychological distress (OR 1.81, 95% CI 1.05-3.12), as did siblings of survivors reporting global psychological distress (OR 2.32, 95% CI 1.08-4.59). Siblings of sarcoma survivors reported more somatization than did siblings of leukemia survivors (OR 2.07, 95% CI 1.05-3.98). These findings suggest that siblings of long-term childhood cancer survivors are psychologically healthy in general. There are, however, small subgroups of siblings at risk for long-term psychological impairment who may benefit from preventive risk-reduction strategies during childhood while their sibling with cancer is undergoing treatment.

    2004-10-11

    The definitive paper by Stuiver and Polach (1977) established the conventions for reporting of {sup 14}C data for chronological and geophysical studies based on the radioactive decay of {sup 14}C in the sample since the year of sample death or formation. Several ways of reporting {sup 14}C activity levels relative to a standard were also established, but no specific instructions were given for reporting nuclear weapons testing (post-bomb) {sup 14}C levels in samples. Because the use of post-bomb {sup 14}C is becoming more prevalent in forensics, biology, and geosciences, a convention needs to be adopted. We advocate the use of fraction modern with a new symbol F{sup 14}C to prevent confusion with the previously used Fm, which may or may not have been fractionation corrected. We also discuss the calibration of post-bomb {sup 14}C samples and the available datasets and compilations, but do not give a recommendation for a particular dataset.

    A dirty-bomb experiment conducted at the INL is used to evaluate the effectiveness and suitability of three different modes of robot control. The experiment uses three distinct user groups to understand how participants’ background and training affect the way in which they use and benefit from autonomy. The results show that the target mode, which involves automated mapping and plume tracing together with a point and click tasking tool, provides the best performance for each group. This is true for objective performance such as source detection and localization accuracy as well as subjective measures such as perceived workload, frustration and preference. The best overall performance is achieved by the Explosive Ordinance Disposal group which has experience in both robot teleoperation and dirty bomb response. The user group that benefits least from autonomy is the Nuclear Engineers that have no experience with either robot operation or dirty bomb response. The group that benefits most from autonomy is the Weapons of Mass Destruction Civil Response Team that has extensive experience related to the task, but no robot training.

    Major terrorist events, such as the recent attacks in Ankara, Sinai, and Paris, can have profound effects on a nation's values, attitudes, and prejudices. Yet psychological evidence testing the impact of such events via data collected immediately before and after an attack is understandably rare. In the present research, we tested the independent and joint effects of threat (the July 7, 2005, London bombings) and political ideology on endorsement of moral foundations and prejudices among two nationally representative samples (combined N = 2,031) about 6 weeks before and 1 month after the London bombings. After the bombings, there was greater endorsement of the in-group foundation, lower endorsement of the fairness-reciprocity foundation, and stronger prejudices toward Muslims and immigrants. The differences in both the endorsement of the foundations and the prejudices were larger among people with a liberal orientation than among those with a conservative orientation. Furthermore, the changes in endorsement of moral foundations among liberals explained their increases in prejudice. The results highlight the value of psychological theory and research for understanding societal changes in attitudes and prejudices after major terrorist events. © The Author(s) 2015.

    Full Text Available Sustained and stable development of forest resources has been focused on world attention, prevention and control of forest fires have also been widespread attention around the world. To extinguish the fire in the forest-fire spot quickly and effectively, a self-triggering fire-extinguishing bomb fuze sensor is designed, and which properties are simulation and analysis. Simulation results show that fire-extinguishing bomb is being placed in the fire, fusible link burn out quickly in high temperature conditions, compressed spring is released, the firing pin was ejected to impact percussion cap so as to detonate explosives, powder extinguishing agent is uniformly blasted, powder is coated on the combustion source to make it extinguished so that the quick and reliable long-range extinguishment is achieved. The abilities of extinguishing fire bombs are significantly improved, it is not only energy- efficient and environmental but also solving problems about the long-range out fire effectively. Therefore, it has good application value to protect the safety of life and property indeed.

    The aim of this study is to describe the radiologic imaging findings of primary, secondary, tertiary, and quaternary blast injuries in patients injured in the Boston Marathon bombing on April 15, 2013. A total of 43 patients presenting to three acute care hospitals and undergoing radiologic investigation within 7 hours of the time of the bombing on April 15, 2013, were included in this study. The radiographic and CT features of these patients were evaluated for imaging findings consistent with primary, secondary, tertiary, and quaternary blast injury. There were no pulmonary or gastrointestinal manifestations of the primary blast wave on imaging. Secondary blast injuries identified on imaging included a total of 189 shrapnel fragments identified in 32 of the 43 patients. The shrapnel was identified most often in the soft tissues of the leg (36.5%), thigh (31.2%), and pelvis (13.2%). Imaging identified 125 ball bearings, 10 nails, one screw, 44 metal fragments, and nine other (gravel, glass, etc.) foreign bodies. Injuries from the Boston Marathon bombing were predominantly from the secondary blast wave and resulted in traumatic injuries predominantly of the lower extremities. The most common shrapnel found on radiologic evaluation was the ball bearing.

    The aim of this study was to evaluate the imaging findings of head and neck injuries in patients from the Boston Marathon bombing. A total of 115 patients from the Boston Marathon bombing presenting to four hospitals who underwent imaging to evaluate for head and neck injuries were included in the study. Twelve patients with positive findings on radiography or cross-sectional imaging were included in the final analysis. The radiographic, computed tomography (CT), and magnetic resonance (MR) imaging features of these patients were evaluated for the presence of shrapnel and morphological abnormality. Head and neck injuries were seen in 12 out of 115 patients presenting to the four hospitals. There were secondary blast injuries to the head and neck in eight patients, indicated by the presence of shrapnel on imaging. In the four patients without shrapnel, there were two with subgaleal hematomas, one with facial contusion and one with mastoid injury. There were two patients with subarachnoid hemorrhage, one with brain contusion, one with cerebral laceration, and one with globe rupture. There was frontal bone, nasal bone, and orbital wall fracture in one patient each. Imaging identified 26 shrapnel fragments, 21 of which were ball bearings. Injuries to the head and neck region identified on imaging from the Boston Marathon bombing were not common. The injuries seen were predominantly secondary blast injuries from shrapnel, and did not result in calvarial penetration of the shrapnel fragments.

    Identifying patients in need of a life-saving intervention (LSI) during a mass casualty event is a priority. We hypothesized that real-time, instantaneous sample entropy (SampEn) could predict the need for LSI in the Boston Marathon bombing victims. Severely injured Boston Marathon bombing victims (n = 10) had sample entropy (SampEn) recorded upon presentation using a continuous 200-beat rolling average in real time. Treating clinicians were blinded to real-time results. The correlation between SampEn, injury severity, number, and type of LSI was examined. Victims were males (60%) with a mean age of 39.1 years. Injuries involved lower extremities (50.0%), head and neck (24.2%), or upper extremities (9.7%). Sample entropy negatively correlated with Injury Severity Score (r = -0.70; P = .023), number of injuries (r = -0.70; P = .026), and the number and need for LSI (r = -0.82; P = .004). Sample entropy was reduced under a variety of conditions. (Table see text). Sample entropy strongly correlates with injury severity and predicts LSI after blast injuries sustained in the Boston Marathon bombings. Sample entropy may be a useful triage tool after blast injury. © 2013.

    2013-12-01

    This study examined the psychological impact of the Boston Marathon bombing using data from an ongoing longitudinal study of Boston-area veterans with posttraumatic stress disorder (PTSD; N = 71). Participants were assessed by telephone within 1 week of the end of the event; 42.3% of participants reported being personally affected by the bombings and/or the manhunt that followed. The majority of them reported that the bombing reminded them of their own traumas and/or caused other emotional distress. Examination of change in posttraumatic stress disorder (PTSD) symptoms from a prebombing assessment an average of 2 months earlier to 1 week after the event revealed no significant change in symptoms across the sample as a whole. However, examination of patterns of change at the individual level revealed significant correlations (r = .33; p = .005) between distress at the time of the event and change in total PTSD symptom severity, with this effect accounted for primarily by increases in intrusion and avoidance symptoms (rs = .35 and .31, ps = .002 and .008, respectively). Findings of this study should raise awareness of the potential impact of terror attacks, mass shootings, and other events of this type on the well-being of individuals with histories of trauma and/or pre-existing PTSD.

    The Boston Marathon terrorist bombing that occurred on April 15, 2013 illustrates the importance of a cohesive, efficient management for the operating room and perioperative services. Conceptually, emotional intelligence (EI) is a form of social intelligence used by individuals in leadership positions to monitor the feelings and emotions of their team while implementing a strategic plan. To describe the experience of caring for victims of the bombing at a large tertiary care center and provide examples demonstrating the importance of EI and its role in the management of patient flow and overall care. A retrospective review of trauma data was performed. Data regarding patient flow, treatment types, treatment times, and outcomes were gathered from the hospital's electronic tracking system and subsequently analyzed. Analyses were performed to aggregate the data, identify trends, and describe the medical care. Immediately following the bombing, a total of 35 patients were brought to the emergency department (ED) with injuries requiring immediate medical attention. 10 of these patients went directly to the operating room on arrival to the hospital. The first victim was in an operating room within 21 minutes after arrival to the ED. The application of EI in managerial decisions helped to ensure smooth transitions for victims throughout all stages of their perioperative care. EI provided the fundamental groundwork that allowed the operating room manager and nurse leaders to establish the calm and coordinated leadership that facilitated patient care and teamwork.

    Considering the ongoing loss of aquatic habitats, anthropogenic ponds are gaining importance as substitute habitats. It is therefore important to assess their functioning in comparison to their natural precursors. Here we assess the biodiversity value of sodic bomb crater ponds by comparing their gamma diversity to that of natural reference habitats, astatic soda pans, and assess their importance on the landscape level by studying alpha and beta diversity. We studied aquatic organisms ranging from algae to vertebrates in a dense cluster of 54 sodic bomb crater ponds in Central Europe. Despite the overall small area of the pond cluster, gamma diversity was comparable to that found in surveys of natural habitats that encompassed much wider spatial and temporal scales. We also found a considerable number of species shared with reference habitats, indicating that these anthropogenic habitats function as important refuge sites for several species that are associated with the endangered soda pans. Moreover, we found a number of regionally or worldwide rare species. Among the components of beta diversity, species replacement dominated community assembly. Individual ponds contributed similarly to beta diversity in terms of replacement, being equally important for maintaining high gamma diversity and emphasising the role of the pond network rather than individual ponds. This pattern was seen in all studied groups. Bomb crater ponds therefore acted as important contributors to aquatic biodiversity. Considering the tremendous losses of ponds throughout Europe, anthropogenic ponds should be taken into consideration in nature conservation, especially when occurring in pond networks.

    Though about 20% of working age breast cancer survivors do not return to work after treatment, few studies have addressed risk factors for unemployment. The majority of studies on occupational consequences of breast cancer focus on non-employment, which is a mixture of sickness absence, unemployment, retirement pensions and other reasons for not working. Unemployment in combination with breast cancer may represent a particular challenge for these women. The aim of the present study is therefore to analyze the risk for unemployment in the years following diagnosis and treatment for breast cancer. This study included 14,750 women diagnosed with breast cancer in Denmark 2001-2009 identified through a population-based clinical database and linked with information from Danish administrative population based registers for information on labour market affiliation, socio-demography and co-morbid conditions. Multivariable analyses were performed by Cox's proportional hazard models. Two years after treatment, 81% of patients were still part of the work force, 10% of which were unemployed. Increasing duration of unemployment before breast cancer was associated with an adjusted HR = 4.37 (95% CI: 3.90-4.90) for unemployment after breast cancer. Other risk factors for unemployment included low socioeconomic status and demography, while adjuvant therapy did not increase the risk of unemployment. Duration of unemployment before breast cancer was the most important determinant of unemployment after breast cancer treatment.

    With the growing number of childhood cancer survivors in the US, it is important to assess the well-being of these individuals, particularly during the transitional phase of adolescence. Data about adolescent survivors' overall health and quality of life will help identify survivor subgroups most in need of targeted attention to successfully transition to adulthood. This ancillary study to the Childhood Cancer Survivor Study focused on children 15-19 years of age who had been diagnosed with cancer before the age of 4 years. A cohort of siblings of pediatric cancer survivors of the same ages served as a comparison sample. Adolescent health was assessed using the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) survey. The teen survey was sent to 444 survivor teens and 189 siblings. Of these, 307(69%) survivors and 97 (51%) siblings completed and returned the survey. The overall health profiles of siblings and survivors were similar. Among survivors, females scored significantly below males on satisfaction, discomfort, and disorders domains. Survivors diagnosed with central nervous system tumors scored less favorably than leukemia survivors in the global domains of satisfaction and disorders. In general, adolescent survivors fare favorably compared to healthy siblings. However, identification of the subset of pediatric cancer survivors who are more vulnerable to medical and psychosocial disorders in adolescence provides the opportunity for design and implementation of intervention strategies that may improve quality of life.

    Improvised explosive devices (IEDs) such as pipe bombs are weapons used to detrimentally affect people and communities. A readily accessible brand of exploding targets called Tannerite® has been identified as a potential material for abuse as an explosive in pipe bombs. The ability to recover and genotype DNA from such weapons may be vital in the effort to identify suspects associated with these devices. While it is possible to recover DNA from post-blast fragments using short tandem repeat markers (STRs), genotyping success can be negatively affected by low quantities of DNA, degradation, and/or PCR inhibitors. Alternative markers such as insertion/null (INNULs) and single nucleotide polymorphisms (SNPs) are bi-allelic genetic markers that are shorter genomic targets than STRs for amplification, which are more likely to resist degradation. In this study, we constructed pipe bombs that were spiked with known amounts of biological material to: 1) recover "touch" DNA from the surface of the device, and 2) recover traces of blood from the ends of wires (simulated finger prick). The bombs were detonated with the binary explosive Tannerite® using double-base smokeless powder to initiate the reaction. DNA extracted from the post-blast fragments was quantified with the Quantifiler® Trio DNA Quantification Kit. STR analysis was conducted using the GlobalFiler® Amplification Kit, INNULs were amplified using an early-access version of the InnoTyper™ 21 Kit, and SNP analysis via massively parallel sequencing (MPS) was performed using the HID-Ion Ampliseq™ Identity and Ancestry panels using the Ion Chef and Ion PGM sequencing system. The results of this study showed that INNUL markers resulted in the most complete genetic profiles when compared to STR and SNP profiles. The random match probabilities calculated for samples using INNULs were lower than with STRs when less than 14 STR alleles were reported. These results suggest that INNUL analysis may be well suited for

    Because overexpression of the gastrin-releasing peptide receptor (GRPR) has been reported on various cancer types, for example, prostate cancer and breast cancer, targeting this receptor with radioligands might have a significant impact on staging and treatment of GRPR-expressing tumors. NeoBOMB1 is a novel DOTA-coupled GRPR antagonist with high affinity for GRPR and excellent in vivo stability. The purpose of this preclinical study was to further explore the use of NeoBOMB1 for theranostic application by determining the biodistribution of 68Ga-NeoBOMB1 and 177Lu-NeoBOMB1. PC-3 tumor-xenografted BALB/c nu/nu mice were injected with either approximately 13 MBq/250 pmol 68Ga-NeoBOMB1 or a low (∼1 MBq/200 pmol) versus high (∼1 MBq/10 pmol) peptide amount of 177Lu-NeoBOMB1, after which biodistribution and imaging studies were performed. At 6 time points (15, 30, 60, 120, 240, and 360 min for 68Ga-NeoBOMB1 and 1, 4, 24, 48, 96, and 168 h for 177Lu-NeoBOMB1) postinjection tumor and organ uptake was determined. To assess receptor specificity, additional groups of animals were coinjected with an excess of unlabeled NeoBOMB1. Results of the biodistribution studies were used to determine pharmacokinetics and dosimetry. Furthermore, PET/CT and SPECT/MRI were performed. Injection of approximately 250 pmol 68Ga-NeoBOMB1 resulted in a tumor and pancreas uptake of 12.4 ± 2.3 and 22.7 ± 3.3 percentage injected dose per gram (%ID/g) of tissue, respectively, at 120 min after injection. 177Lu-NeoBOMB1 biodistribution studies revealed a higher tumor uptake (17.9 ± 3.3 vs. 11.6 ± 1.3 %ID/g of tissue at 240 min after injection) and a lower pancreatic uptake (19.8 ± 6.9 vs. 105 ± 13 %ID/g of tissue at 240 min after injection) with the higher peptide amount injected, leading to a significant increase in the absorbed dose to the tumor versus the pancreas (200 pmol, 570 vs. 265 mGy/MBq; 10 pmol, 435 vs. 1393 mGy/MBq). Using these data to predict patient dosimetry, we found a

    Little is known about differences by sexual orientation in explanatory factors of breast cancer survivors' quality of life, anxiety, and depression. Survivors were recruited from a cancer registry and additional survivors recruited through convenience methods. Data were collected via telephone survey from all 438 survivors, who were disease free and diagnosed with non-metastatic breast cancer an average of 5 years earlier. To explain quality of life, anxiety, and depression, we focused on sexual orientation as the primary independent factors, in addition, considering demographic, psychosocial, clinical, and functional factors as correlates. Sexual orientation had indirect associations with each of the outcomes, through disease-related and demographic factors as well as psychosocial and coping resources. The various explanatory models explain between 36% and 50% of the variance in outcomes and identified areas of strengths and vulnerabilities in sexual minority compared with heterosexual survivors. This study's findings of strengths among specific subgroups of sexual minority compared with heterosexual survivors require further explorations to identify the reasons for this finding. Most of the identified vulnerabilities among sexual minority compared with heterosexual survivors of breast cancer are amenable to change by interventions.

    A nanoscale , microfabricated waveguide structure can in - principle be used to trap atoms in well - defined locations and enable strong photon-atom interactions . A neutral - atom platform based on this microfabrication technology will be prealigned , which is especially important for quantum - control applications. At present, there is still no reported demonstration of evanescent - field atom trapping using a microfabricated waveguide structure. We described the capabilities established by our team for future development of the waveguide atom - trapping technology at SNL and report our studies to overcome the technical challenges of loading cold atoms into the waveguide atom traps, efficient and broadband optical coupling to a waveguide, and the waveguide material for high - power optical transmission. From the atomic - physics and the waveguide modeling, w e have shown that a square nano-waveguide can be utilized t o achieve better atomic spin squeezing than using a nanofiber for first time.

    Work with individual atoms and molecules aims to demonstrate that miniaturized electronic, optical, magnetic, and mechanical devices can operate ultimately even at the level of a single atom or molecule. As such, atomic and molecular manipulation has played an emblematic role in the development of the field of nanoscience. New methods based on the use of the scanning tunnelling microscope (STM) have been developed to characterize and manipulate all the degrees of freedom of individual atoms and molecules with an unprecedented precision. In the meantime, new concepts have emerged to design molecules and substrates having specific optical, mechanical and electronic functions, thus opening the way to the fabrication of real nano-machines. Manipulation of individual atoms and molecules has also opened up completely new areas of research and knowledge, raising fundamental questions of "Optics at the atomic scale", "Mechanics at the atomic scale", Electronics at the atomic scale", "Quantum physics at the atomic sca...

    Psychological quality of life (QOL), health-related QOL (HRQOL), and life satisfaction outcomes and their associated risk factors are reviewed for the large cohort of survivors and siblings in the Childhood Cancer Survivor Study (CCSS). This review includes previously published manuscripts that used CCSS data focused on psychological outcome measures, including the Brief Symptom Inventory (BSI-18), the Medical Outcomes Survey Short Form-36 (SF-36), the Cantril Ladder of Life, and other self-report questionnaires. Comparisons and contrasts are made between siblings and survivors, and to normative data when available, in light of demographic/health information and abstracted data from the medical record. These studies demonstrate that a significant proportion of survivors report more symptoms of global distress and poorer physical, but not emotional, domains of HRQOL. Other than brain tumor survivors, most survivors report both good present and expected future life satisfaction. Risk factors for psychological distress and poor HRQOL are female sex, lower educational attainment, unmarried status, annual household income less than $20,000, unemployment, lack of health insurance, presence of a major medical condition, and treatment with cranial radiation and/or surgery. Cranial irradiation impacted neurocognitive outcomes, especially in brain tumor survivors. Psychological distress also predicted poor health behaviors, including smoking, alcohol use, fatigue, and altered sleep. Psychological distress and pain predicted use of complementary and alternative medicine. Overall, most survivors are psychologically healthy and report satisfaction with their lives. However, certain groups of childhood cancer survivors are at high risk for psychological distress, neurocognitive dysfunction, and poor HRQOL, especially in physical domains. These findings suggest targeting interventions for groups at highest risk for adverse outcomes and examining the positive growth that remains

    In 2009, the American College of Sports Medicine convened an expert roundtable to issue guidelines on exercise for cancer survivors. This multidisciplinary group evaluated the strength of the evidence for the safety and benefits of exercise as a therapeutic intervention for survivors. The panel concluded that exercise is safe and offers myriad benefits for survivors including improvements in physical function, strength, fatigue, quality of life (QOL), and possibly recurrence and survival. Recommendations for situations in which deviations from the US Physical Activity Guidelines for Americans are appropriate were provided. Here, we outline a process for implementing the guidelines in clinical practice, and provide recommendations for how the oncology care provider can interface with the exercise and physical therapy community.

    Three waves of resilience research have resulted in resilience-enhancing educational and therapeutic interventions. In the first wave of inquiry, researchers explored the traits and environmental characteristics that enabled people to overcome adversity. In the second wave, researchers investigated the processes related to stress and coping. In the third wave, studies examined how people grow and are transformed following adverse events, often leading to self-actualize, client creativity and spirituality. In this article the authors examined data from a study, "Forgiveness, Resiliency, and Survivorship among Holocaust Survivors" funded by the John Templeton Foundation ( Greene, Armour, Hantman, Graham, & Sharabi, 2010 ). About 65% of the survivors scored on the high side for resilience traits. Of the survivors, 78% engaged in processes considered resilient and felt they were transcendent or had engaged in behaviors that help them grow and change over the years since the Holocaust, including leaving a legacy and contributing to the community.

    This study investigates how cancer survivors construct their identities and the impact on their psychological health, as measured by depression and survivor self-efficacy. Fourteen young adult survivors of pediatric cancer participated in a customized social networking and video blog intervention program, the LIFECommunity, over a 6-month period. Survivors were asked to share their stories on various topics by posting video messages. Those video blog postings, along with survey data collected from participants, were analyzed to see how cancer survivors expressed their identities, and how these identities are associated with survivors' psychosocial outcomes. In survivors who held negative stereotypes about cancer survivors, there was a positive relationship with depression while positive stereotypes had a marginal association with cancer survivor efficacy. Findings indicate that although pediatric cancer survivors often do not publicly discuss a "cancer survivor identity," they do internalize both positive and negative stereotypes about cancer survivorship. It is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.

    This volume introduces readers to the structured conflict analysis as a tool of social science research and uses this instrument exemplarily to analyze systematically and on a broad basis the various conflicts that are associated with Iran both domestically and in foreign policy - beyond popular stereotypes such as the ''bomb''. The 13 contributions draw a complex picture of the conflicts with and in Iran and reflect the various aspects of these conflicts from different perspectives and at a high methodological and theoretical level. The nuclear program is examined, inter alia through the eyes of four major theories of International Relations. In addition, the analyses are concerned with the regional security dimension, the relationship USA-Iran, the role of national preferences, and the effect of national processes to the Iranian foreign policy.

    To determine if attendance at a specialized clinic for adult survivors of childhood cancer is associated with better rates of adherence to the Children's Oncology Group (COG) Long-term Follow-up (LTFU) guidelines for cardiomyopathy screening. We conducted a retrospective population-based study using administrative data in Ontario, Canada of 5-year survivors diagnosed between 1986 and 2005 at risk of therapy-related late cardiomyopathy. Patients were classified into three groups based on the recommended frequency of screening: annual, every 2 years, and every 5 years. Of 1811 eligible survivors followed for median 7.8 years (range 0-14.0), patients were adherent to screening for only 8.6% of their period of follow-up. Survivor clinic utilization had the strongest association with increased rates of adherence: when compared to no attendance, ≥ 5 clinic visits/10-year period had RR of adherence of 10.6 (95% CI 5.7-19.5) in the annual group, 3.3 (95% CI 2.3-4.8) in the every 2-year group, and 2.3 (95% CI 1.6-3.2) in the every 5-year group. Additional factors associated with increased adherence after adjusting for clinic attendance included annual assessment by a general practioner, female sex, diagnosis prior to 2003, and living in a rural area. In a model of specialized survivor care, increased clinic utilization is associated with improved patient adherence to COG LTFU cardiomyopathy screening guidelines. Specialized survivor clinics may improve health outcomes in survivors through improved adherence to screening. However, rates of adherence remain suboptimal and further multifacetted strategies need to be explored to improve overall rates of screening in adult survivors of childhood cancer.

    To assess the frequency of fibromyalgia among a population of Holocaust survivors in Israel as well as the occurrence of post-traumatic stress disorder (PTSD) and concurrent psychiatric symptoms, including depression and anxiety among survivors. Eighty-three survivors of the Nazi Holocaust and 65 age-matched individuals not exposed to Nazi occupation were recruited. Physical examination and manual tender point assessment was performed for the establishment of the diagnosis of fibromyalgia and information was collected regarding quality of life (SF-36), physical function and health (FIQ), psychiatric symptoms (SCL-90) and PTSD symptoms (CAPS). Significantly increased rates of fibromyalgia were identified among Holocaust survivors compared with controls (23.81% vs. 10.94, p<0.05). Significantly increased rates of posttraumatic symptoms and measures of mental distress were also identified among survivors. The results indicate a significantly increased prevalence of fibromyalgia among Holocaust survivors six decades after the end of the Second World War. This finding furthers our knowledge regarding the long-term effect of stress on the development of fibromyalgia.

  16. Adult survivors of childhood sexual abuse: survivor's disclosure and nurse therapist's response.

    1994-12-01

    Recent literature pertinent to adult survivors suggests that childhood sexual abuse is a serious problem, and that disclosure is on the rise. The aftereffects of childhood sexual abuse can cause dysfunction in various aspects of the survivor's physical and mental health. Understanding the traumagenic dynamics of childhood sexual abuse and its aftereffects provides direction for the nurse therapist during both the client's disclosure and intervention planning. This knowledge assists the therapist in promoting mental health and healing, as well as providing comfort for the therapist. The nurse therapist's reactions to the client's disclosure can affect the way the client feels about disclosure and the therapeutic relationship. If a negative message is conveyed to the survivor at the time of disclosure, the feelings of betrayal, stigmatization, and powerlessness that the survivor experienced as a child will be replicated. This can damage the therapeutic relationship and delay the healing process. When disclosure is received and acted upon in a sensitive, therapeutic manner, the survivor is empowered and can enter with the nurse therapist into an effective therapeutic alliance. Nurse therapists should gain awareness of the types of emotional responses that can be engendered in the health professional during disclosure. Awareness of these emotional reactions can lead to the identification of coping strategies useful to both the therapist and the adult survivor. Coping strategies useful to the therapist include maintaining adequate boundaries, understanding oneself and one's responses to sexual-abuse issues, utilizing ongoing consultation or supervision, and preventing burnout.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose Survivors of childhood cancer may experience financial burden as a result of health care costs, particularly because these patients often require long-term medical care. We sought to evaluate the prevalence of financial burden and identify associations between a higher percentage of income spent on out-of-pocket medical costs (≥ 10% of annual income) and issues related to financial burden (jeopardizing care or changing lifestyle) among survivors of childhood cancer and a sibling comparison group. Methods Between May 2011 and April 2012, we surveyed an age-stratified, random sample of survivors of childhood cancer and a sibling comparison group who were enrolled in the Childhood Cancer Survivor Study. Participants reported their household income, out-of-pocket medical costs, and issues related to financial burden (questions were adapted from national surveys on financial burden). Logistic regression identified associations between participant characteristics, a higher percentage of income spent on out-of-pocket medical costs, and financial burden, adjusting for potential confounders. Results Among 580 survivors of childhood cancer and 173 siblings, survivors of childhood cancer were more likely to have out-of-pocket medical costs ≥ 10% of annual income (10.0% v 2.9%; P report spending a higher percentage of their income on out-of-pocket medical costs, which may influence their health-seeking behavior and potentially affect health outcomes. Our findings highlight the need to address financial burden in this population with long-term health care needs.

    On April 15, 2013, at approximately 2:49 p.m. EDT, two improvised explosive devices detonated near the finish line of the 117th Boston Marathon. Patients were transported from the scene to several trauma centers, including the authors' institution. Plastic surgical assessment of patients began in the Emergency Department and then rapidly expanded as the scope of the incident became clear. Daily interdisciplinary meetings involving the acute care surgery, orthopedic surgery, plastic surgery, and nursing services were convened in order to coordinate operating room schedules and treatment plans. An interdisciplinary weekly clinic continued until all patient goals had been reached. Twenty-four patients were treated at Beth Israel Deaconess Medical Center within the first 24 hours of the Boston Marathon bombing. Seven were triaged directly to the operating room from the Emergency Department. The Division of Plastic Surgery was directly involved with the care of 11 patients, all of whom were treated surgically within 24 hours of the bombing. Patients were aged 23 to 50 years old. All 11 patients sustained lower extremity injuries with gross contamination. Four patients also sustained significant upper extremity trauma. Injuries included extremity amputations and fractures, soft-tissue loss, impaction of nails and other debris, burns, ocular injury, and ruptured tympanic membranes. Twenty-four patients received acute care at Beth Israel Deaconess Medical Center following the Boston Marathon bombing. Institution of dedicated interdisciplinary daily rounds, protected operating room block time, and joint follow-up clinic allowed for efficient early diagnosis and treatment of patients' injuries.

    Turell, S C; Armsworth, M W

    2000-02-01

    This study was an exploratory analysis of the variables which differentiated incest survivors who self-mutilate from those who do not. A sample of women incest survivors (N = 84) were divided into two groups based on the presence or absence of self-mutilation. Participants included both community and clinical populations. A packet consisting of a demographic questionnaire, Sexual Attitudes Survey, Diagnostic Inventory of Personality and Symptoms, Dissociative Events Scale and the Beck Depression Inventory was completed by each participant. Demographic, incest, and family of origin variables distinguished the self-mutilating women from those who did not. These include ethnicity and educational experiences; duration, frequency, and perpetrator characteristics regarding the incest; and multiple abuses, instability, birth order, and loss of mother in one's family of origin. Psychological and physical health concerns also differentiated between the two groups. Many variables may differentiate between women incest survivors who self-mutilate from those who do not. A rudimentary checklist to describe the lives of incest survivors who self-mutilate resulted from these findings. The importance of the concept of embodiment is also discussed.

  6. Endocrine sequelae in childhood cancer survivors.

    Science.gov (United States)

    Casano Sancho, Paula

    2017-11-01

    Thanks to the advances in cancer treatment, the five-year survival rate after childhood cancer has increased up to 80%. Therefore 1/500 young adults will be a survivor. Endocrine sequelae are most common, affecting 40-60% of survivors. The most frequent sequelae include growth failure and gonadal and thyroid diseases. Sequelae occur more frequently in survivors from central nervous system tumors, leukemia, and lymphoma. Their development will depend on the type of cancer, its location, age at diagnosis, and treatment administered. Treatments associated to more endocrine sequels are cranial radiotherapy and hematopoietic cell transplantation. Because of the high prevalence of endocrine sequelae, international guidelines recommend endocrinologists to prospectively evaluate the survivors. As some of these endocrine changes will not develop until adult life, transition programs should be implemented, and active investigation should be made to decrease the endocrine consequences of cancer treatment.

    Full Text Available The electronic damage feasibility and the operational characteristics of the high power electromagnetic pulse bomb shot by shipboard gun are analyzed. As the destruction of the electronic components caused by the high power electromagnetic pulse is hard to evaluate, the spatial distribution of the anti-ship missiles is analyzed, and the strategic model for the continuous fire is built. Aimed at the maximum damage effectiveness, the crux of the lasted shift shooting tactics is a TSP problem. The genetic algorithm is applied in the TSP problem. Simulation experiments demonstrate that the model and the algorithm are effective.

  10. Technical approaches to on-person bomb detection for counter-terrorism

    Science.gov (United States)

    Alonso, Steve

    2004-09-01

    Western democracies can reasonably expect an increase in homicide bombings as a major terrorist weapon of choice causing fear and economic damage far in excess of the actual loss of life and property caused by the explosives. The terrorists will strike at public venues (transportation, shopping, sporting events, schools, and governmental facilities) greatly multiplying the complexity and cost of effective defense. The author argues for accelerated research in multiple electromagnetic and passive technologies and fielding single and multi-sensor fixed, mobile and manportable systems to attempt to stay one step ahead of the growing reality of global terrorism.

    A growing literature concludes that terrorism impacts the economy, yet less is known about its impact on utility. This paper estimates the impact of the 2013 Boston Marathon Bombing on well-being, by exploiting representative U.S. daily data. Using both a regression discontinuity and an event study design, whereby the 2012 Boston marathon serves as a counterfactual, we find a sharp reduction in well-being, equivalent to a two percentage point rise in annual unemployment.

    Hayashi, Shigeru; Koito, Atsushi; Hishiki, Manabu

    1992-01-01

    The size distribution of water test sprays generated by a prefilming airblast atomizer used for aeroengines was measured in swirling and non-swirling flows with the well established laser scattering particle sizing technique. Atomizing air velocity (or pressure difference) was varied in a range wider than the conditions of actual engines. The Sauter Mean Diameter (SMD) decreased at approximately a 1.5 power of the atomizing air velocity, being a higher velocity index than the previously reported values of 1 to 1.2. It was unexpectedly found that the effect of the liquid/air flow ratio was small. Since swirling flow increased the SMD at lower air velocities yet decreased it at higher ones, it is suggested that the reverse flow near the nozzle pintle adversely affects atomization.

  14. Single atom electrochemical and atomic analytics

    Science.gov (United States)

    Vasudevan, Rama

    In the past decade, advances in electron and scanning-probe based microscopies have led to a wealth of imaging and spectroscopic data with atomic resolution, yielding substantial insight into local physics and chemistry in a diverse range of systems such as oxide catalysts, multiferroics, manganites, and 2D materials. However, typical analysis of atomically resolved images is limited, despite the fact that image intensities and distortions of the atoms from their idealized positions contain unique information on the physical and chemical properties inherent to the system. Here, we present approaches to data mine atomically resolved images in oxides, specifically in the hole-doped manganite La5/8Ca3/8MnO3, on epitaxial films studied by in-situ scanning tunnelling microscopy (STM). Through application of bias to the STM tip, atomic-scale electrochemistry is demonstrated on the manganite surface. STM images are then further analyzed through a suite of algorithms including 2D autocorrelations, sliding window Fourier transforms, and others, and can be combined with basic thermodynamic modelling to reveal relevant physical and chemical descriptors including segregation energies, existence and strength of atomic-scale diffusion barriers, surface energies and sub-surface chemical species identification. These approaches promise to provide tremendous insights from atomically resolved functional imaging, can provide relevant thermodynamic parameters, and auger well for use with first-principles calculations to yield quantitative atomic-level chemical identification and structure-property relations.

  15. Complexities in the Use of Bomb-Curve Radiocarbon to Determine Time Since Death of Human Skeletal Remains

    Energy Technology Data Exchange (ETDEWEB)

    Ubelaker, D H; Buchholz, B A

    2005-04-26

    Atmospheric testing of nuclear weapons during the 1950s and early 1960s doubled the level of radiocarbon ({sup 14}C) in the atmosphere. From the peak in 1963, the level of {sup 14}CO{sub 2} has decreased exponentially with a mean life of about 16 years, not due to radioactive decay, but due to mixing with large marine and terrestrial carbon reservoirs. Since radiocarbon is incorporated into all living things, the bomb-pulse is an isotopic chronometer of the past half century. The absence of bomb radiocarbon in skeletonized human remains generally indicates a date of death before 1950. Comparison of the radiocarbon values with the post 1950 bomb-curve may also help elucidate when in the post 1950 era, the individual was still alive. Such interpretation however, must consider the age at death of the individual and the type of tissue sampled.

    Survivors of childhood cancer are at considerable risk of experiencing treatment-related adverse health outcomes. To provide survivors with specialized care focused on these risks during adulthood, the government of Ontario funded a provincial network of specialized survivor clinics in 1999. The aim of this study was to determine whether prior attendance at survivor clinics by adult survivors of childhood cancer was associated with rates of emergency department (ED) visits. This was a population-based, retrospective cohort study using multiple linked administrative health databases. The cohort consisted of all adult survivors of childhood cancer diagnosed between January 1, 1986 and December 31, 2005 in Ontario, Canada. A recurrent event regression model was used to evaluate the association between prior attendance at survivor clinics and the rate of ED visits; adjustments were made for individual, demographic, treatment, and provider characteristics. The study consisted of 3912 adult survivors of childhood cancer. Individuals who had at least 1 prior visit to a survivor clinic had a 19% decreased rate of ED visits in comparison with individuals who had not visited a survivor clinic (adjusted relative rate, 0.81; 95% confidence interval, 0.78-0.85). Each additional prior visit to a survivor clinic was associated with a 5% decrease in the rate of ED visits (adjusted relative rate, 0.95; 95% confidence interval, 0.93-0.96). These results were independent of whether or not survivors received care from a primary care physician. Attendance at a specialized survivor clinic was significantly associated with decreased ED visits among adult survivors of childhood cancer. © 2015 American Cancer Society.

    2009-11-01

    A nuclear bomb particle from Thule containing Pu and U was analyzed using X-ray spectrometry in combination with γ-ray spectrometry and non-destructive α-spectrometry. The main objective was to investigate the possibility to determine the 239Pu and 240Pu isotope ratios. Previously, X-ray spectrometry together with the above-mentioned methods has been successfully applied for radiochemically processed samples, but not for individual particles. In the present paper we demonstrate the power of non-destructive analysis. The 239Pu/( 239Pu+ 240Pu) atom ratio for the Thule particle was determined, using two different approaches, to be 0.93±0.07 and 0.91±0.05. These results are consistent with weapons-grade material and the results obtained by other investigators.

    The survival of Ewing sarcoma (ES) patients has improved since the 1970s but is associated with considerable future health risks. The study population consisted of long-term (> or =5-year) survivors of childhood ES diagnosed before age 21 from 1970 to 1986. Cause-specific mortality was evaluated in eligible survivors (n = 568), and subsequent malignant neoplasms, chronic health conditions, infertility, and health status were evaluated in the subset participating in the Childhood Cancer Survivor Study (n = 403). Outcomes were compared with the US population and sibling control subjects (n = 3899). Logistic, Poisson, or Cox proportional hazards models, with adjustments for sex, age, race/ethnicity, and potential intrafamily correlation, were used. Statistical tests were two-sided. Cumulative mortality of ES survivors was 25.0% (95% confidence interval [CI] = 21.1 to 28.9) 25 years after diagnosis. The all-cause standardized mortality ratio was 13.3 (95% CI = 11.2 to 15.8) overall, 23.1 (95% CI = 17.6 to 29.7) for women, and 10.0 (95% CI = 7.9 to 12.5) for men. The nonrecurrence-progression non-external cause standardized mortality ratio (subsequent non-ES malignant neoplasms and cardiac and pulmonary causes potentially attributable to ES treatment) was 8.7 (95% CI = 6.2 to 12.0). Twenty-five years after ES diagnosis, cumulative incidence of subsequent malignant neoplasms, excluding nonmelanoma skin cancers, was 9.0% (95% CI = 5.8 to 12.2). Compared with siblings, survivors had an increased risk of severe, life-threatening, or disabling chronic health conditions (relative risk = 6.0, 95% CI = 4.1 to 9.0). Survivors had lower fertility rates (women: P = .005; men: P < .001) and higher rates of moderate to extreme adverse health status (P < .001). Long-term survivors of childhood ES exhibit excess mortality and morbidity.

    Médecins Sans Frontières (MSF) has been providing healthcare in Afghanistan since 1981 including specialized health services for trauma patients in Kunduz Trauma Center (KTC) from 2011. On October 3rd, 2015, a US airstrike hit the KTC, killing 42 people including 14 MSF staff. This study aims to demonstrate the impact on healthcare provision, after hospital destruction, by assessing the extent of care provided for trauma and injuries by the MSF KTC and to report on treatment outcomes from January 2014 to June 2015, three months prior to the bombing. This is a descriptive, retrospective review of hospital records. All patients with traumatic injuries registered in the Emergency Department (ED) or hospitalized in In-Patients Department (IPD) and/or Intensive Care Unit (ICU) of KTC between January 2014 and June 2015 were included in the study. A total of 35647 patients were registered in KTC during the study period. 3199 patients registered in the ED were children aged wound surgery followed by orthopedic surgery (27.0%). This study highlights the high burden of traumatic injuries in Kunduz province and MSF Trauma Center's contribution to saving lives, preventing disabilities and alleviating suffering among adults and children within the region. The bombing and destruction of KTC has resulted in a specific gap in critical healthcare services for the local communities in the health system of this war-ravaged region. This suggests the urgent need for reconstruction and re-opening of the center.

    Background Penetrating brain injuries caused by explosions are survived in extremely rare cases only. However, potential casualties of such cases may be encountered by regular physicians even outside a war zone, e.g., due to an assault or terror blast. There is very limited literature to this end; therefore, we report the successful neurosurgical management of a penetrating head injury due to a pipe bomb explosion. Case Description A 19-year-old man was brought to the ER with a swollen, bleeding right orbit, and a severely injured left hand after having sustained an unwitnessed explosion from a self-made pipe bomb. He presented with a GCS (Glasgow Coma Scale) of 15 at time of admission, work-up revealed an intracranial retained metal fragment measuring 5 × 1 × 0.2 cm lodged retro-orbitally and in the skull base. The patient underwent emergent right temporal craniotomy and temporal lobectomy and simultaneous right enucleation before the petrous bone and sphenoid wing lodged metal fragment was successfully removed. Conclusion This case underscores the importance of having a high suspicion for the presence of an intracranial injury and a retained foreign body in the setting of a penetrating head injury. Aggressive and timely workup as well as expeditious surgical management are crucial in these settings and can generate exceptionally good outcomes despite a major trauma. PMID:21246061

    The aim of this study is to describe the imaging findings of abdominal and pelvic injuries in victims of the Boston Marathon bombing. A retrospective review of 87 patients following the Boston Marathon bombing was performed to evaluate for abdominal and pelvic injuries on plain radiography or CT scans of the abdomen and pelvis. Imaging exams were evaluated for shrapnel, soft tissue injury, visceral damage, vascular disruption, and fractures. The injuries were classified as primary, secondary, tertiary, and quaternary blast injuries. Eleven of the 87 patients had positive findings in the abdomen or pelvis (M:F = 7:4, average age 34.6 years). There were 22 ball bearings, two nails, one screw, and two irregular metal fragments in the 11 patients with secondary blast (shrapnel) injuries. There was no peritoneal penetration or visceral injury seen in any of the patients. One patient had multiple transverse process fractures, representing tertiary blast injury. All but one patient had superficial penetrating abdominal or pelvic injuries secondary to shrapnel. There were no cases of bowel or solid visceral organ injuries due to the lack of peritoneal violation from the relatively low-powered explosions. Absence of peritoneal penetration by shrapnel indicates no need for laparotomy following low-powered explosions.

    The role of repeated exposure to collective trauma in explaining response to subsequent community-wide trauma is poorly understood. We examined the relationship between acute stress response to the 2013 Boston Marathon bombings and prior direct and indirect media-based exposure to three collective traumatic events: the September 11, 2001 (9/11) terrorist attacks, Superstorm Sandy, and the Sandy Hook Elementary School shooting. Representative samples of residents of metropolitan Boston (n = 846) and New York City (n = 941) completed Internet-based surveys shortly after the Boston Marathon bombings. Cumulative direct exposure and indirect exposure to prior community trauma and acute stress symptoms were assessed. Acute stress levels did not differ between Boston and New York metropolitan residents. Cumulative direct and indirect, live-media-based exposure to 9/11, Superstorm Sandy, and the Sandy Hook shooting were positively associated with acute stress responses in the covariate-adjusted model. People who experience multiple community-based traumas may be sensitized to the negative impact of subsequent events, especially in communities previously exposed to similar disasters. © The Author(s) 2015.

    Age validation of bluenose Hyperoglyphe antarctica was sought using the independent bomb chronometer procedure. Radiocarbon ((14) C) levels were measured in core micro-samples from 12 otoliths that had been aged using a zone count method. The core (14) C measurement for each fish was compared with the value on a surface water reference curve for the calculated birth year of the fish. There was good agreement, indicating that the line-count ageing method described here is not substantially biased. A second micro-sample was also taken near the edge of nine of the otolith cross-sections to help define a bomb-carbon curve for waters deeper than 200-300 m. There appears to be a 10 to 15 year lag in the time it takes the (14) C to reach the waters where adult H. antarctica are concentrated. The maximum estimated age of this species was 76 years, and females grow significantly larger than males. Von Bertalanffy growth curves were estimated, and although they fit the available data reasonably well, the lack of aged juvenile fish results in the K and t(0) parameters being biologically meaningless. Consequently, curves that are likely to better represent population growth were estimated by forcing t(0) to be -0·5. © 2010 NIWA.

Se intenta mostrar como la resistencia de los gobiernos y los ejecutivos aprueba índices críticos en las leyes antiterroristas. A la luz de una reciente encuesta sobre legislación antiterrorista mundial, los casos donde la legislación antiterrorista ha sido bloqueada ha llegado a ser verdaderamente crítica. A este fin, este artículo se pregunta por qué la legislación antiterrorista se bloquea cuando esto sucede. Para responder a esta cuestión, se han testado tres variables: la composición de los gobiernos, la opinión pública-basada en los niveles de terror en sus medios, y el nivel de acuerdos ejecutivos. Para testar estas variables, se han evaluado dos casos: la evolución de la legislación antiterrorista antes de los ataques de la ciudad de Oklahoma en 1995 y antes de los atentados de Londres de 2005. En la evaluación de los casos, los debates legislativos y ejecutivos han ocurrido antes de los ataques terroristas examinados y luego se han comparado los dos casos con el Reino Unido en 1974 y los Estados Unidos en 2001 cuando la legislación antiterrorista inicia su camino. Este artículo concluye que el nivel de acuerdos ejecutivos y la composición de los gobiernos tiene el mayor poder de explicación en determinadas decisiones antiterroristas que llevarán a secundar la legislación antiterrorista o no.Palabras clave: ataques terroristas a Londres, legislación antiterrorista, Estados Unidos, Reino Unido___________________________ABSTRACT:This article scrutinizes the legislative reactions to the Oklahoma City Bombing and the 2005 London Bombings to try to decipher why counter-terror legislation was substantially blocked after these attacks.  It finds that the partisan composition of the government and

    Much of our understanding of physics in the last 30-plus years has come from research on atoms, photons, and their interactions. Collecting information previously scattered throughout the literature, Modern Atomic Physics provides students with one unified guide to contemporary developments in the field. After reviewing metrology and preliminary material, the text explains core areas of atomic physics. Important topics discussed include the spontaneous emission of radiation, stimulated transitions and the properties of gas, the physics and applications of resonance fluorescence, coherence, cooling and trapping of charged and neutral particles, and atomic beam magnetic resonance experiments. Covering standards, a different way of looking at a photon, stimulated radiation, and frequency combs, the appendices avoid jargon and use historical notes and personal anecdotes to make the topics accessible to non-atomic physics students. Written by a leader in atomic and optical physics, this text gives a state-of-the...

    We show that aberration-corrected scanning transmission electron microscopy operating at low accelerating voltages is able to analyze, simultaneously and with single atom resolution and sensitivity, the local atomic configuration, chemical identities, and optical response at point defect sites in monolayer graphene. Sequential fast-scan annular dark-field (ADF) imaging provides direct visualization of point defect diffusion within the graphene lattice, with all atoms clearly resolved and identified via quantitative image analysis. Summing multiple ADF frames of stationary defects produce images with minimized statistical noise and reduced distortions of atomic positions. Electron energy-loss spectrum imaging of single atoms allows the delocalization of inelastic scattering to be quantified, and full quantum mechanical calculations are able to describe the delocalization effect with good accuracy. These capabilities open new opportunities to probe the defect structure, defect dynamics, and local optical properties in 2D materials with single atom sensitivity.

    A Greek philosopher called DEMOCRITUS (c. 460-370 BC) first introduced the concept of atoms (which means indivisible). His atoms do not precisely correspond to our atoms of today, which are not indivisible, but made up of a nucleus (protons with positive charge and neutrons which have no charge) and orbiting electrons (with negative charge). Indeed, in the solar atmosphere, the temperature is suc...

    The British Childhood Cancer Survivor Study (BCCSS) provides the first detailed investigation of employment and occupation to be undertaken in a large population-based cohort. Previous studies have been limited by design issues such as using small numbers of survivors with specific diagnoses, and involved limited assessment of employment status and occupational level. The BCCSS includes 17,981 5-year survivors of childhood cancer. Employment status and occupational level were ascertained by questionnaire from eligible survivors (n = 14,836). Multivariate logistic regression was used to explore factors associated with employment and occupation, and to compare survivors to their demographic peers in the general population. Employment status was available for 10,257 survivors. Gender, current age, cancer type, radiotherapy, age at diagnosis and epilepsy were consistently associated with being: employed; unable to work; in managerial or non-manual occupations. Overall, survivors were less likely to be working than expected (OR (99% CI): 0.89 (0.81-0.98)), and this deficit was greatest for irradiated CNS neoplasm survivors (0.34 (0.28-0.41)). Compared to the general population, survivors were fivefold more likely to be unable to work due to illness/disability; the excess was 15-fold among CNS neoplasm survivors treated with radiotherapy. Overall survivors were less likely to be in managerial occupations than expected (0.85 (0.77-0.94)). However, bone sarcoma survivors were more likely to be in these occupations than expected (1.37 (1.01-1.85)) and also similarly for non-manual occupations (1.90 (1.37-2.62)). Survivors of retinoblastoma (1.55 (1.20-2.01)) and 'other' neoplasm group (1.62 (1.30-2.03)) were also more likely to be in non-manual occupations than expected. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    This study aims to evaluate physical, psychosocial, and spiritual factors associated with happiness in breast cancer survivors during the reentry period. It is a cross-sectional study with 283 nonmetastatic breast cancer survivors who completed treatment within 1 year. We included survivors who completed questionnaires on happiness and health-related quality of life (QoL) 2 years after cancer diagnosis. Happiness and QoL was measured using the Subjective Happiness Scale and EORTC QLQ-C30, respectively. Multivariable logistic regression was used to find factors associated with happiness. The mean age of the study participants was 48.5 ± 7.8 years. Among the 283 survivors, 14.5%, 43.8%, 32.5%, and 2.1% reported being "very happy," "happy," "neutral," and "not happy at all," respectively. Happy survivors reported a better general health status and QoL (67.6 vs 49.6; P Happy survivors were more likely to feel certain about the future (27.2% vs 11.9%, P happiness. During the reentry period, breast cancer survivors who are hopeful and have a clear purpose in life are more likely to be happy than those who are not.

    Quality health care for survivors of cancer must evaluate and manage symptoms that are reported at the surveillance visit but are not linked to a cancer recurrence or a new cancer. At present, this does not always occur. This article analyzes quality of health care for survivors of cancer, taking empirical evidence and clinical expertise into consideration. Although emotional distress on the part of the survivor of cancer may exacerbate or even explain the presence of experienced symptoms, there are other potential explanations as well. When survivors present with persistent symptoms (even if unexplained) after cancer diagnosis and treatment, the symptoms can impact the survivor's function and well-being. Oncologists and other providers need to assess and directly target these symptoms for appropriate triage to those who can best help these survivors reduce the symptoms and their impact.

    Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

  20. Reduced male fertility in childhood cancer survivors

    Directory of Open Access Journals (Sweden)

    Sun Hee Lee

    2013-12-01

    Full Text Available With advances in cancer treatment, more pediatric cancer patients have increased their life expectancy. Because cancer-related therapy causes various physical and psychological problems, many male survivors experience later problems with thyroid and sexual functions, and with growth. As outcomes have improved, more survivors need to maintain their reproductive function to maximize their long-term quality of life. Cancer and cancer-related treatment can impair fertility by damage to the testes, to the hypothalamic-pituitary-gonadal axis, or to the genitourinary organs. Prior radiation therapy to the testes, the use of alkylating agents, and central hypogonadism further impair fertility in male survivors of childhood cancer. Following any course of chemotherapy, peripubertal maturation, any testicular volume changes, and symptoms of androgen deficiency should be monitored systematically. If patients request fertility testing, spermatogenesis status can be evaluated either directly by semen analysis or indirectly by determination of the levels of testosterone/gonadotropins and by monitoring any changes in testicular volume. According to the patient's condition, semen cryopreservation, hormonal therapy, or assisted reproduction technologies should be provided.

    Pastoral work with survivors of domestic violence may reveal theological struggles. Understandings of scripture that reinforce a sense of powerlessness and alienation from God may contribute to an impaired relationship and limit resources for healing. One framework for re-imaging a relationship with God is process theology. This framework was applied to a case study for one survivor. The application resulted in a line of inquiry that may assist survivors in their healing process.

    To investigate school absenteeism among childhood cancer survivors and their siblings and examine factors related to absenteeism in survivors. A cross-sectional study was conducted among consecutive cancer survivors attending a large pediatric cancer survivor clinic. Absenteeism rates were obtained for survivors and their closest in age sibling from school report cards. Absenteeism was compared with a population control group of 167752 students using 1-sample t tests. The Child Vulnerability Scale, Pediatric Quality of Life Inventory, and Behavior Assessment System for Children were administered to survivors. Univariate and multiple regression analyses assessed variables associated with days absent. One hundred thirty-one survivors (median age at assessment: 13.4 years, range 8.0-19.2; median age at diagnosis: 9.4 years, range 4.3-17.3) and 77 siblings (median age at assessment: 13 years, age range 7-18) participated. Survivors and siblings missed significantly more school days than the population control group (mean ± SD: 9.6 ± 9.2 and 9.9 ± 9.8 vs 5.0 ± 5.6 days, respectively, P sibling pairs (N = 77), there was no difference in absenteeism (9.6 ± 9.2 vs 9.9 ± 9.8 days, P = .85). Absenteeism in survivors was significantly associated with a low Pediatric Quality of Life Inventory Physical Health Summary Score (P = .01). Parents' perception of their child's vulnerability and emotional and social functioning were not associated with absenteeism. Childhood cancer survivors and siblings miss more school than the general population. The only predictor of absenteeism in survivors is poor physical quality of health. More research should be devoted to school attendance and other outcomes in siblings of childhood cancer survivors. Copyright © 2013 Mosby, Inc. All rights reserved.

    There are limited data on health care use among survivors of young adult cancers. We aimed to describe patterns of hospitalization among a cohort of long-term survivors compared with noncancer controls. Persons diagnosed between the ages of 20 and 44 years with malignancies in Ontario, Canada, from 1992 to 1999, who lived at least 5 years recurrence free, were identified using the Ontario Cancer Registry and matched to noncancer controls. Hospitalizations were determined using hospital discharges, and rates were compared between survivors and controls. The absolute excess rate of hospitalizations was determined for each type of malignancy in survivors per 100 person-years of follow-up. The cohort included 20,275 survivors and 101,344 noncancer controls. During the study period, 6,948 (34.3%) survivors were admitted to the hospital and the adjusted relative rate (ARR) of hospitalizations in survivors compared with controls was 1.51 (95% CI, 1.48 to 1.54). The rate of hospitalization was highest for survivors of upper GI, leukemia, and urologic malignancies. The hospitalization rate (per person) for survivors significantly decreased from 0.22 in the first time period examined (5 to 8 years after diagnosis) to 0.15 in the last time period examined (18 to 20 years after diagnosis, P < .0001). However, at all time periods, survivors were more likely to be hospitalized than controls (ARR at 5 to 8 years, 1.67 [95% CI, 1.57 to 1.81]; ARR at 18 to 20 years, 1.22 [95% CI, 1.08 to 1.37]). Survivors of young adult cancers have an increased rate of hospitalization compared with controls. The rate of hospitalization for 20-year survivors did not return to baseline, indicating a substantial and persistent burden of late effects among this generally young population. © 2015 by American Society of Clinical Oncology.

    Stroke leads to a substantial societal economic burden. Loss of productivity among stroke survivors is a significant contributor to the indirect costs associated with stroke. We aimed to characterize productivity and factors associated with employability in stroke survivors. We used the Canadian Community Health Survey 2011-2012 to identify stroke survivors and employment status. We used multivariable logistic models to determine the impact of stroke on employment and on factors associated with employability, and used Heckman models to estimate the effect of stroke on productivity (number of hours worked/week and hourly wages). We included data from 91,633 respondents between 18 and 70 years and identified 923 (1%) stroke survivors. Stroke survivors were less likely to be employed (adjusted OR 0.39, 95% CI 0.33-0.46) and had hourly wages 17.5% (95% CI 7.7-23.7) lower compared to the general population, although there was no association between work hours and being a stroke survivor. We found that factors like older age, not being married, and having medical comorbidities were associated with lower odds of employment in stroke survivors in our sample. Stroke survivors are less likely to be employed and they earn a lower hourly wage than the general population. Interventions such as dedicated vocational rehabilitation and policies targeting return to work could be considered to address this lost productivity among stroke survivors. © 2016 S.

    Background Childhood cancer survivors develop gastrointestinal malignancies more frequently and at a younger age than the general population, but risk factors for their development have not been well characterized. Objective To determine the risk and associated risk factors for gastrointestinal subsequent malignant neoplasms (SMN) in childhood cancer survivors. Design Retrospective cohort study. Setting The Childhood Cancer Survivor Study, a multi-center study of childhood cancer survivors diagnosed between 1970 and 1986. Patients 14,358 survivors of a malignancy diagnosed at cancer survivors than the general population (95% confidence interval [CI]: 3.5-6.1). Colorectal cancer SIR was 4.2 (95% CI: 2.8-6.3). The highest gastrointestinal SMN risk was associated with abdominal radiation (SIR=11.2, 95% CI: 7.6-16.4). However, survivors not exposed to radiation had a significantly increased risk (SIR=2.4, 95% CI-1.4-3.9). In addition to abdominal radiation, high dose procarbazine (RR=3.2, 95% CI 1.1-9.4) and platinum drugs (RR 7.6, 95% CI: 2.3-25.5) independently increased the gastrointestinal SMN risk. Limitations This cohort has not yet attained an age at which gastrointestinal malignancy risk is greatest. Conclusions Childhood cancer survivors, particularly those exposed to abdominal radiation, are at increased risk for gastrointestinal SMN. These findings suggest that surveillance of at-risk childhood cancer survivors should commence at a younger age than recommended for the general population. PMID:22665813

    Adult survivors of childhood brain tumors experience multiple, significant, lifelong deficits as a consequence of their malignancy and therapy. Current survivorship literature documents the substantial impact such impairments have on survivors' physical health and quality of life. Psychosocial reports detail educational, cognitive, and emotional limitations characterizing survivors as especially fragile, often incompetent, and unreliable in evaluating their circumstances. Anecdotal data suggest some survivors report life experiences similar to those of healthy controls. The aim of our investigation was to determine whether life satisfaction in adult survivors of childhood brain tumors differs from that of healthy controls and to identify potential predictors of life satisfaction in survivors. This cross-sectional study compared 78 brain tumor survivors with population-based matched controls. Chi-square tests, t tests, and linear regression models were used to investigate patterns of life satisfaction and identify potential correlates. Results indicated that life satisfaction of adult survivors of childhood brain tumors was similar to that of healthy controls. Survivors' general health expectations emerged as the primary correlate of life satisfaction. Understanding life satisfaction as an important variable will optimize the design of strategies to enhance participation in follow-up care, reduce suffering, and optimize quality of life in this vulnerable population. © 2014 by Association of Pediatric Hematology/Oncology Nurses.

  14. The carcinogenic risks of low-LET and high-LET ionizing radiations

    Energy Technology Data Exchange (ETDEWEB)

    Fabrikant, J.I. (Lawrence Berkeley Lab., CA (USA))

    1989-08-01

    New information is available concerning the carcinogenic effects of radiation and the implications for risk assessment and risk management. This information comes from further follow-up of the epidemiological studies of the Japanese atomic bomb survivors, patients irradiated medically for cancer and allied conditions, and workers exposed in various occupations. In the Japanese atomic bomb survivors the carcinogenic risks are estimated to be somewhat higher than previously, due to the reassessment of the atomic-bomb dosimetry, further follow-up with increase in the number of excess cancer deaths, particularly in survivors irradiated early in life, and changes in the methods of analysis to compute the age-specific risks of cancer. Because of the characteristics of the atomic bomb survivor series as regards sample size, age and sex distribution, duration for follow-up, person-years at risk, and type of dosimetry, the mortality experience of the atomic bomb survivors was selected by the UNSCEAR Committee and the BEIR V Committee as the more appropriate basis for projecting risk estimates for the general population. In the atomic bomb survivors, the dose-effect relationship for overall cancer mortality other than leukemia is consistent with linearity below 3 Gy, while the dose-effect relationship for leukemia, excluding chronic lymphatic leukemia, conforms best to a linear-quadratic function. The shape of the dose-incidence curve at low doses still remains uncertain, and the data do not rule out the possible existence of a threshold for an neoplasm. The excess relative risk of mortality from all cancers combined is estimated to be 1.39 per Gy (shielded kerma), which corresponds to an absolute risk of 10.0 excess cancer deaths per 10,000 PYGy; the relative risks is 1.41 at 1 Gy (organ-absorbed dose), and an absolute risk of 13.07 excess cancer deaths per 10,000 PYGy. 19 refs.

    There is growing interest in potential long-term outcomes following intensive care, but few researchers have studied the prevalence of multiple symptoms or the association between pain and other symptoms. To investigate the prevalence of anxiety, depression, fatigue, sleep disturbance and post-traumatic stress symptoms (PTSS) among intensive care survivors 3 months and 1 year after being discharged from an intensive care unit (ICU) and to determine whether pain is associated with higher prevalence of these symptoms 3 months and 1 year after ICU stay. Exploratory, longitudinal cohort of intensive care survivors from two mixed ICUs in a tertiary referral hospital in Norway. Intensive care survivors completed surveys at 3 months (n = 118) and 1 year (n = 89) after ICU discharge. Clinical Trials: NCT02279212. Prevalence rates of intensive care survivors' symptoms were pain 58 (49·2%), anxiety/depression 24/118 (20·8%), fatigue 18/118(15·3%), PTSS 15 (12·8%) and sleep disturbance 58/118 (49·2%) at 3 months after ICU discharge (n = 118). Prevalence rates at 1 year (n = 89) changed only slightly to pain 34 (38·2%), anxiety/depression 17 (20·0%), fatigue 12 (13·8%), PTSS 13 (15·1%) and sleep disturbance 40/89 (46·5%). Associations were strong between pain and presence of sleep disturbance, anxiety/depression, PTSS and fatigue. Intensive care survivors have multiple symptoms and the prevalence rates of these symptoms remained almost unchanged from 3 months to 1 year after ICU discharge. The presence of pain was associated with high odds for the presence of sleep disturbance, anxiety/depression, PTSS and fatigue, compared to a no-pain group. ICU survivors may benefit from targeted interventions designed to alleviate the symptom burden. Knowledge about ICU survivor's prevalence and risk for having multiple symptoms may help health care professionals to give better care, if needed, to the ICU survivors. © 2017 British Association of Critical Care

In order to facilitate the consolidation of the material covered, various problems are included, together with complete solutions. The emphasis on theory enables the reader to appreciate the fundamental assumptions underlying standard theoretical constructs and to embark on independent research projects. The fourth edition of Theoretical Atomic Physics contains an updated treatment of the sections involving scattering theory and near-threshold phenomena manifest in the behaviour of cold atoms (and molecules). Special attention is given to the quantization of weakly bound states just below the continuum threshold and to low-energy scattering and quantum reflection just above. Particular emphasis is laid on the fundamen...

  1. Atomic diffusion in stars

    CERN Document Server

    Michaud, Georges; Richer, Jacques

    2015-01-01

    This book gives an overview of atomic diffusion, a fundamental physical process, as applied to all types of stars, from the main sequence to neutron stars. The superficial abundances of stars as well as their evolution can be significantly affected. The authors show where atomic diffusion plays an essential role and how it can be implemented in modelling.  In Part I, the authors describe the tools that are required to include atomic diffusion in models of stellar interiors and atmospheres. An important role is played by the gradient of partial radiative pressure, or radiative acceleration, which is usually neglected in stellar evolution. In Part II, the authors systematically review the contribution of atomic diffusion to each evolutionary step. The dominant effects of atomic diffusion are accompanied by more subtle effects on a large number of structural properties throughout evolution. One of the goals of this book is to provide the means for the astrophysicist or graduate student to evaluate the importanc...

  2. Maximally Atomic Languages

    Directory of Open Access Journals (Sweden)

    Janusz Brzozowski

    2014-05-01

    Full Text Available The atoms of a regular language are non-empty intersections of complemented and uncomplemented quotients of the language. Tight upper bounds on the number of atoms of a language and on the quotient complexities of atoms are known. We introduce a new class of regular languages, called the maximally atomic languages, consisting of all languages meeting these bounds. We prove the following result: If L is a regular language of quotient complexity n and G is the subgroup of permutations in the transition semigroup T of the minimal DFA of L, then L is maximally atomic if and only if G is transitive on k-subsets of 1,...,n for 0 <= k <= n and T contains a transformation of rank n-1.

  3. The Chemical Time Bomb: How to Predict when it Will Go off

    Directory of Open Access Journals (Sweden)

    Bourg A. C. M.

    2014-07-01

    Full Text Available The Chemical Time Bomb Concept (CTB refers to “events resulting in the delayed occurrence of harmful effects due to the mobilization of chemicals stored in soils and sediments”. Why do some ecosystems accept contaminants with no (little impact? If soils and sediments are sinks for metallic contaminants it is because their hydrogeochemical environment is favorable. Why do they release them at some point? Oversaturation of the ecosystem is often suggested as the cause. We propose here a new approach to this now well accepted concept. The soil or sediment retains its metallic pollutants as long as the controlling parameters, i.e. mostly pH and Eh, are stable. The pH or Eh buffer capacity of the solid is therefore the controlling parameter to avoid the release of metallic contaminants to the hydrosphere. Examples of natural and contaminated systems will be presented.

  4. Superradiance energy extraction, black-hole bombs and implications for astrophysics and particle physics

    CERN Document Server

    Brito, Richard; Pani, Paolo

    2015-01-01

    This volume gives a unified picture of the multifaceted subject of superradiance, with a focus on recent developments in the field, ranging from fundamental physics to astrophysics. Superradiance is a radiation enhancement process that involves dissipative systems. With a 60 year-old history, superradiance has played a prominent role in optics, quantum mechanics and especially in relativity and astrophysics. In Einstein's General Relativity, black-hole superradiance is permitted by dissipation at the event horizon, which allows energy extraction from the vacuum, even at the classical level. When confined, this amplified radiation can give rise to strong instabilities known as "blackhole bombs'', which have applications in searches for dark matter, in physics beyond the Standard Model and in analog models of gravity. This book discusses and draws together all these fascinating aspects of superradiance.

  5. Plastic surgeons and the management of trauma: from the JFK assassination to the Boston Marathon bombing.

    Luce, Edward A; Hollier, Larry H; Lin, Samuel J

    2013-11-01

    The fiftieth anniversary of the death by assassination of President John Kennedy is an opportunity to pay homage to his memory and also reflect on the important role plastic surgeons have played in the management of trauma. That reflection included a hypothetical scenario, a discussion of the surgical treatment of Kennedy (if he survived) and Governor Connally. The scenario describes the management of cranioplasty in the presence of scalp soft-tissue contracture, reconstruction of the proximal trachea, reconstitution of the abdominal wall, and restoration of a combined radius and soft-tissue defect. The development of diagnostic and therapeutic advances over the past 50 years in the care of maxillofacial trauma is described, including the evolution of imaging, timing of surgery, and operative techniques. Finally, contemporary measures of triage in situations involving mass casualties, as in the Boston Marathon bombings, complete the dedication to President Kennedy.

  6. Psychiatry department response to the Boston Marathon bombings within a level-1 trauma center.

    Oser, Megan; Shah, Sejal B; Gitlin, David

    2015-01-01

    In this article we present how the consultation-liaison and psychology divisions of an academic medical center's Department of Psychiatry responded in the first week after the Boston Marathon bombings, specifically in the context of disaster response guidelines and evidence-based approaches to acute trauma. Since the department had to address several complicated matters at multiple levels within the hospital system, we highlight unexpected issues unique to this particular event as they arose within the primary domains of our involvement. This article aims to (1) provide a descriptive analysis of how we enacted disaster and trauma guidelines and evidence-based care within a hospital setting, (2) shed light on the unique and unexpected administrative and systemic issues encountered in our response, and (3) discuss lessons learned, including opportunities to improve trauma-related care.

    Samples originating from the time period after 1950 can be radiocarbon dated utilising the 14C bomb peak as a calibration curve. The applicability of "radiocarbon dating" of recent organic human material for the determination of the time of death of humans was tested. The radiocarbon results from hair and lipid samples from individuals with known date of death were compared with the results from two individuals with unknown time of death. An estimate of the year of death for the unknowns could be derived by this way. Due to the long turnover time of collagen in human bones it is not possible to use the radiocarbon content of bone collagen for a reliable estimate. In order to study the time dependence of the collagen turnover we tested "soft" chemical methods for the isolation of collagen from the bone matrix. First radiocarbon results of this investigation are presented.

    2014-01-01

    Background Terrorist attacks have been shown to precipitate posttraumatic stress disorder (PTSD) symptomatology in children and adolescents, particularly among youths with high exposure to media coverage surrounding such events. Media exposure may be particularly likely to trigger PTSD symptoms in youths with high physiological reactivity to stress or with prior psychopathology or exposure to violence. We examined the interplay between media exposure, preattack psychopathology, autonomic nervous system (ANS) reactivity, and prior violence exposure in predicting PTSD symptom onset following the terrorist attack at the 2013 Boston Marathon. Methods A community sample of 78 adolescents (mean age = 16.7 years, 65% female) completed a survey about the bombings, including media exposure to the event and PTSD symptoms. All respondents participated in a study assessing psychopathology prior to the attack, and sympathetic and parasympathetic reactivity to a laboratory-based stressor was assessed in a subset (N = 44) of this sample. We examined the associations of media exposure, ANS reactivity, preattack psychopathology, and prior violence exposure with onset of PTSD symptoms related to the bombings. Results Media exposure, preattack psychopathology, and prior violence exposure were associated with PTSD symptoms. Moreover, media exposure interacted with sympathetic reactivity to predict PTSD symptom onset, such that adolescents with lower levels of sympathetic reactivity developed PTSD symptoms only following high exposure to media coverage of the attack. Conclusions We provide novel evidence that physiological reactivity prior to exposure to an unpredictable traumatic stressor predicts PTSD symptom onset. These findings have implications for identifying youths most vulnerable to PTSD following wide-scale trauma. PMID:24995832

  9. Lessons in posttraumatic stress disorder from the past: Venezuela floods and Nairobi bombing.

    Science.gov (United States)

    Carlos Otero, Juan; Njenga, Frank G

    2006-01-01

    Identification and treatment of posttraumatic stress disorder (PTSD) are important following a disaster. Insights into how these aims can be achieved may be obtained from previous disasters. This article describes mental health initiatives following the 1999 flooding in Vargas State, Venezuela, and the 1998 U.S. Embassy bombing in Nairobi, Kenya. Following the Vargas State floods, a specialist mental health center devoted to the diagnosis, treatment, and follow-up of PTSD was established. Awareness and acceptance of the clinic was promoted by media campaigns and community-based activities. After 18 months, approximately 5000 people had been screened, of whom 62% were diagnosed with PTSD and treated. Moreover, the clinic's activities had expanded to include treatment of other medical conditions and assistance with nonmedical needs. Following the Nairobi bombing, a mass media campaign was initiated to create awareness of PTSD symptoms and help victims come to terms with their experience. This campaign was found to be well received and helpful. In addition, counselors were trained to support people living or working close to the blast. These examples show that mental health initiatives are feasible after a disaster and highlight a number of issues: (1) The intervention should be tailored to the needs of the target population; (2) Communication should be simple and appropriate; (3) Community-based activities are valuable in promoting awareness and acceptance of mental health initiatives; (4) Reducing the stigma often associated with mental health problems is important; and (5) The mass media can be helpful in promoting awareness of mental health issues following major trauma.

    2013-01-01

    Nueva Luz is an English and Spanish quality of life (QOL) intervention developed to address the educational needs of Latina breast cancer survivors and provide strategies to assist in their transition into survivorship. A qualitative approach was used to evaluate the English and Spanish educational intervention (Nueva Luz). A purposive sample of eight Latina breast cancer survivors was selected from the group who received the intervention to participate in a digitally recorded interview. Data was analyzed using thematic analysis. Findings provide evidence that the one-on-one tailored approach is a feasible and acceptable method of providing a bilingual psychosocial intervention. The provision of printed bilingual information along with the verbal instruction from a bilingual and culturally competent health care provider can be effective in helping Latina breast cancer survivor's transition successfully into survivorship, improve QOL and contribute to better patient outcomes. The study informs our understanding of the cultural context in patient education content and delivery of psychosocial interventions. The findings may also have relevance for other ethnic minority cancer survivors.

    In the aftermath of a potentially traumatic event, people may experience a range of mental health outcomes, including subclinical symptoms and distress. There is growing evidence that trauma survivors with subclinical symptoms are at increased risk of developing later psychiatric disorders, and this is especially the case with severe injury survivors. There is a need to develop evidence-based, early, brief interventions for those who are at risk of developing trauma-related psychopathology. To date, interventions for this at-risk group have largely been derived from expert consensus. This study therefore aimed to understand the early psychosocial difficulties and perceived needs from the perspective of trauma survivors to further inform intervention development. Forty-three survivors of a serious injury, identified as high risk for developing trauma-related psychopathology, were interviewed and qualitative methods (Thematic Analysis) were used to synthesize the data gathered. Participants described 5 main stressors: trauma-related psychological reactions, relationship stress, unsatisfactory services and support systems, reduced functioning, and negative thoughts and emotions in relation to recovery. In addition, participants described 3 main factors that were helpful in recovery: positive coping, professional support, and social support. These findings can inform posttrauma intervention development for those at risk of later psychological symptoms. In particular, the results support approaches focusing on promoting activity, supporting social relationships, stress and arousal management, and cognitive restructuring. In addition, future interventions might helpfully target rumination, worry, and reexperiencing symptoms. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Survivors of pediatric cancer have elevated risks of mortality and morbidity. Many late adverse effects associated with cancer treatment (eg, second cancers and cardiac and pulmonary disease) are also associated with cigarette smoking, and this suggests that survivors who smoke may be at high risk for these conditions. This study examined the self-reported smoking status for 9397 adult survivors of childhood cancer across 3 questionnaires (median time interval, 13 years). The smoking prevalence among survivors was compared with the smoking prevalence among siblings and the prevalence expected on the basis of age-, sex-, race-, and calendar time-specific rates in the US population. Multivariable regression models examined characteristics associated with longitudinal smoking patterns across all 3 questionnaires. At the baseline, 19% of survivors were current smokers, whereas 24% of siblings were current smokers, and 29% were expected to be current smokers on the basis of US rates. Current smoking among survivors dropped to 16% and 14% on follow-up questionnaires, with similar decreases in the sibling prevalence and the expected prevalence. Characteristics associated with consistent never-smoking included a higher household income (relative risk [RR], 1.16; 95% confidence interval [CI], 1.08-1.25), higher education (RR, 1.32; 95% CI, 1.22-1.43), and receipt of cranial radiation therapy (RR, 1.08; 95% CI, 1.03-1.14). Psychological distress (RR, 0.86; 95% CI, 0.80-0.92) and heavy alcohol drinking (RR, 0.64; 95% CI, 0.58-0.71) were inversely associated. Among ever-smokers, a higher income (RR, 1.17; 95% CI, 1.04-1.32) and education (RR, 1.23; 95% CI, 1.10-1.38) were associated with quitting, whereas cranial radiation (RR, 0.86; 95% CI, 0.76-0.97) and psychological distress (RR, 0.80; 95% CI, 0.72-0.90) were associated with not having quit. The development of adverse health conditions was not associated with smoking patterns. Despite modest declines in smoking prevalence

  14. Poststroke spasticity: sequelae and burden on stroke survivors and caregivers.

    Zorowitz, Richard D; Gillard, Patrick J; Brainin, Michael

    2013-01-15

    Among the estimated 20% to 40% of stroke survivors who develop spasticity, the burden of this condition on patients, caregivers, and society is substantial. Stroke survivors with spasticity may experience reductions in their ability to perform activities of daily living and in their health-related quality of life. The occurrence of spasticity in stroke survivors may also result in an increased burden on their caregivers, who exhibit poorer physical and emotional health as compared with the general population. The responsibilities that caregivers have to the stroke survivor--in terms of providing medical care, protecting from falls, and assisting with feeding and hygiene, among other tasks of daily living--must be balanced with their responsibilities to other family members and to themselves. Caregivers of stroke survivors often report a feeling of confinement with little opportunity for relief, and although social support can be helpful, it is frequently limited in its availability. In terms of the socioeconomic burden of spasticity after stroke, recent data point to a 4-fold increase in health care costs associated with stroke survivors with spasticity compared with stroke survivors without spasticity. Thus, it is important to reduce the burden of spasticity after stroke. Consequently, effective spasticity treatment that reduces spasticity and the level of disability experienced by stroke survivors will likely increase their functioning and their health-related quality of life and will also result in a diminished burden on their caregivers.

    Stroke is a leading cause of disability and sequelae may include physical, emotional, and cognitive impairments. The methods employed to cope with distress, both emotional and cognitive, have not been evaluated in individuals post-stroke. However, research in traumatic brain injury (TBI) suggests that executive function is positively correlated with adaptive coping and negatively correlated with maladaptive coping strategies (Krpan et al., 2007). Examination of these constructs post-stroke may assist with enriching our understanding of cognitive and emotional symptomatology and optimize rehabilitation strategies. The present study aimed to assess the association between executive function and coping strategies in a sample of chronic stroke survivors. The researchers hypothesized that executive function would be positively correlated with adaptive coping strategies and negatively correlated with maladaptive coping strategies. Fifteen stroke survivors were administered a battery of cognitive tests assessing executive function and also completed the Ways of Coping Questionnaire (WAYS), a self-report coping measure. Analyses indicated that executive function deficits were related to increased avoidant coping. Contrary to expectations, executive function was not significantly related to active coping. In addition, post hoc analyses revealed that executive function was a significant predictor of avoidant coping after controlling for demographics. Our data, in accordance with prior work in TBI, suggests that executive function and aspects of coping are associated. Rehabilitation strategies that improve executive function may also lead to utilization of adaptive coping strategies. Research has shown that aerobic exercise increases activation in the frontal lobe and improves executive function (Colcombe & Kramer, 2003; Colcombe et al., 2004). Future studies should examine whether aerobic exercise positively affects executive function and coping in stroke survivors.

    We want to introduce an atomic pendulum whose driving force (torque) is due to the quantum vacuum fluctuations. Applying the well-known Casimir-Polder effect to a special configuration (a combined structure of an atomic nanostring and a conducting plate), an atomic pendulum (Casimir atomic pendulum) is designed. Using practically acceptable data corresponding to the already known world of nanotechnology and based on reasonable/reliable numerical estimates, the period of oscillation for the pendulum is computed. This pendulum can be considered as both a new micro(nano)-electromechanical system and a new simple vacuum machine. Its design may be considered as a first step towards realizing the visualized vacuum (Casimir) clock{exclamation_point}.

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen. Discussion of the classical hydrogen...

    This systematic literature review assesses the evidence regarding benefits of peer support services for bereaved survivors of sudden or unexpected death. Reports were included that addressed peer support services for adults who experienced death of a family member, close friend, or coworker. Of the 32 studies meeting all inclusion criteria, most showed evidence that peer support was helpful to bereaved survivors, reducing grief symptoms and increasing well-being and personal growth. Studies also showed benefits to providers of peer support, including increased personal growth and positive meaning in life. Several studies addressed the growing trend of Internet-based peer support programs, finding that these are beneficial in part due to their easy accessibility. Peer support appears to be especially valuable for survivors of suicide loss, a result that may be related to stigma and lack of support from family and friends experienced by many suicide survivors. The reviewed studies provide consistent evidence that peer support is beneficial to bereaved survivors.

    Drawing from trauma theory, psychodynamic conceptualization, developmental psychology, clinical data, and personal experience, this article portrays a life haunted by tragedy predating its victims. Healthy child development is outlined, with particular attention to socialization and theological perspectives. Key characteristics of trauma are delineated, highlighting the nuances of trauma that are most harmful. As is the case with general trauma, Holocaust survivors are described as evincing survivor's guilt and paranoia in response to their experiences. Divergent disorders resulting from the Holocaust are described for 1st-generation and 2nd-generation survivors, respectively. Primary trauma responses and pervasive attitudes of survivors are shown to have harmful ramifications on their children's personality and worldview as well as on their interpersonal and theistic object relations. These limitations translate into problems in the adult lives of second generation survivors.

Preference of Wave Atoms on other transformations has been due to its sparser expansion, adaptability to the direction of local pattern, and sharp frequency localization. In this scheme, we had tried to spread the watermark in an image so that the information at one place is very small and undetectable. In order to extract the...

  16. Hirshfeld atom refinement.

    Hirshfeld atom refinement (HAR) is a method which determines structural parameters from single-crystal X-ray diffraction data by using an aspherical atom partitioning of tailor-made ab initio quantum mechanical molecular electron densities without any further approximation. Here the original HAR method is extended by implementing an iterative procedure of successive cycles of electron density calculations, Hirshfeld atom scattering factor calculations and structural least-squares refinements, repeated until convergence. The importance of this iterative procedure is illustrated via the example of crystalline ammonia. The new HAR method is then applied to X-ray diffraction data of the dipeptide Gly-l-Ala measured at 12, 50, 100, 150, 220 and 295 K, using Hartree-Fock and BLYP density functional theory electron densities and three different basis sets. All positions and anisotropic displacement parameters (ADPs) are freely refined without constraints or restraints - even those for hydrogen atoms. The results are systematically compared with those from neutron diffraction experiments at the temperatures 12, 50, 150 and 295 K. Although non-hydrogen-atom ADPs differ by up to three combined standard uncertainties (csu's), all other structural parameters agree within less than 2 csu's. Using our best calculations (BLYP/cc-pVTZ, recommended for organic molecules), the accuracy of determining bond lengths involving hydrogen atoms from HAR is better than 0.009 Å for temperatures of 150 K or below; for hydrogen-atom ADPs it is better than 0.006 Å(2) as judged from the mean absolute X-ray minus neutron differences. These results are among the best ever obtained. Remarkably, the precision of determining bond lengths and ADPs for the hydrogen atoms from the HAR procedure is comparable with that from the neutron measurements - an outcome which is obtained with a routinely achievable resolution of the X-ray data of 0.65 Å.

    Since the theoretical works of L. De Broglie (1924) and the famous experiment of Davisson and Germer (1927), we know that a wave is linked with any particle of mass m by the relation {lambda} = h/(mv), where {lambda} is the wavelength, v the particle velocity and h is the Planck constant. The basic principle of the interferometry of any material particle, atom, molecule or aggregate is simple: using a simple incident wave, several mutually consistent waves (with well-defined relative phases) are generated and controllable phase-shifts are introduced between them in order to generate a wave which is the sum of the previous waves. An interference figure is obtained which consists in a succession of dark and bright fringes. The atomic interferometry is based on the same principle but involves different techniques, different wave equations, but also different beams, sources and correlations which are described in this book. Because of the small possible wavelengths and the wide range of possible atomic interactions, atomic interferometers can be used in many domains from the sub-micron lithography to the construction of sensors like: inertial sensors, gravity-meters, accelerometers, gyro-meters etc. The first chapter is a preliminary study of the space and time diffraction of atoms. The next chapters is devoted to the description of slit, light separation and polarization interferometers, and the last chapter treats of the properties of Bose-Einstein condensates which are interesting in atomic interferometry.

    Cancer survivors often experience cognitive difficulties after treatment completion. Although chemotherapy enhances risk for cognitive problems, it is likely only one piece of a complex puzzle that explains survivors' cognitive functioning. Loneliness may be one psychosocial risk factor. The current studies included both subjective and objective cognitive measures and tested whether lonelier breast cancer survivors would have more concentration and memory complaints and experience more concentration difficulties than their less lonely counterparts. The relationship between loneliness and cognitive function was tested among three samples of breast cancer survivors. Study 1 was a sample of breast cancer survivors (n = 200) who reported their concentration and memory problems. Study 2a was a sample of breast cancer survivors (n = 185) and noncancer controls (n = 93) who reported their concentration and memory problems. Study 2b was a subsample of Study 2a breast cancer survivors (n = 22) and noncancer controls (n = 21) who completed a standardized neuropsychological test assessing concentration. Studies 1 and 2a revealed that lonelier women reported more concentration and memory problems than less lonely women. Study 2b utilized a standardized neuropsychological continuous performance test and demonstrated that lonelier women experienced more concentration problems than their less lonely counterparts. These studies demonstrated that loneliness is linked to concentration and memory complaints and the experience of concentration problems among breast cancer survivors. The results were also highly consistent across three samples of breast cancer survivors. These data suggest that loneliness may be a risk factor for cognitive difficulties among cancer survivors.

    The prevalence of osteoporosis was statistically significantly higher among female Holocaust survivors than among those who were not exposed to the Holocaust. These findings support the importance of nutrition and environmental conditions during childhood and adolescence on BMD in older adults. Holocaust survivors during childhood and adolescence experienced undernutrition and lack of exercise and sunlight. The study aimed to establish if Holocaust survivors have higher prevalence of osteoporosis than subjects who were not Holocaust survivors. Seventy-three female Jewish Holocaust survivors > or = 60 years old and 60 female European-born Jews > or =60 years old who were not in the Holocaust were examined. BMD was measured using DXA of the lumbar spine and hips. The Cochran-Armitage trend test was used to test for an increasing trend in decreased BMD in the Holocaust survivors versus controls. Among Holocaust survivors 54.8% had osteoporosis, 39.7% osteopenia, and 5.5% normal BMD, whereas among controls 25.0% had osteoporosis, 55.0% osteopenia, and 20.0% normal BMD (p = 0.0001). In those who were Holocaust survivors 58.0% had osteoporosis, 34.0% osteopenia, and 8.0% normal BMD, whereas among controls 20.0% had osteoporosis, 57.8% osteopenia, and 22.2% normal BMD (p = 0.0003). In those > or =17 years old in 1945, among Holocaust survivors 47.8% had osteoporosis, 52.2% osteopenia and none had normal BMD, whereas among controls 40.0% had osteoporosis, 46.7% osteopenia, and 13.3% normal BMD (p = 0.28). The prevalence of osteoporosis was significantly higher among Holocaust survivors.
