    Imtiaz, Salman; Qayyum, Shahid; Kafouri, Hala; Al Khoiter, Mohammad; Askar, Akram

    2011-07-01

    We report a 20-year-old man who presented to our emergency room with a history of polyuria, weakness, constipation, nausea, and vomiting of two months duration. History and clinical examination revealed a significant weight loss and mild hepatomegaly. Laboratory investigations revealed hypokalemia, hypernatremia, and severe metabolic acidosis and anemia. Ultra-sound of the abdomen revealed enlarged kidneys without hydronerphrosis. The patient developed paralysis due to further decline in serum potassium level, which improved after an aggressive fluid and electrolyte management. He was investigated extensively for polyuria and type of acidosis. The kidney biopsy showed interstitial leukemic infiltration. He was managed accordingly and recovered from the condition. This case demonstrates an unusual presentation of a hematological malignancy, which was a diagnostic as well as a management challenge.

    Full Text Available Reactive arthritis is a form of seronegative spondyloarthritis temporally triggered by an apparent infection, usually gastroenteritis or urethritis. This arthritis typically starts within a few weeks of the inciting infection. It commonly affects young adults and is strongly associated with the MHC class I antigen HLA-B27. Here we present an interesting case of young man with HLA-B27 positive reactive arthritis in whom the presumptive diagnosis was reached early in the course of his illness.

    A 32-year old man was referred to our institution for transthoracic echocardiography (TTE) following detection of an incidental murmur on physical examination before blood donation. He was asymptomatic with no significant medical history. Physical examination revealed dual heart sounds with a grade II/VI systolic murmur heard in the left sternal border. An ECG was in normal sinus rhythm. TTE was performed (figure 1A-C, online supplementary videos 1-4) followed by cardiac CT angiography (CTA) (figure 1D,E).heartjnl;heartjnl-2018-313223v1/F1F1F1Figure 1(A) Transthoracic echocardiography, parasternal left ventricular long axis view.

    2017-01-01

    A 19-year-old man presented with a fever, convulsions, and loss of consciousness at our hospital. The patient had a Glasgow Coma Scale score of 12. Influenza B virus infection was diagnosed using the rapid test kit, and an eight-fold increase in the serum levels of anti-influenza B virus antibody was confirmed using the complement fixation test. Brain magnetic resonance imaging showed multifocal high-signal lesions, and an electroencephalogram showed diffuse slowing of the background activity, indicating acute encephalopathy. After treatment with peramivir and methylprednisolone for 3 days, the patient was discharged without any neurological impairment. This was a case of influenza B infection associated with acute encephalopathy in a healthy young man.

  10. "Man points": masculine capital and young men's health.

    2013-01-01

    Health behaviors are important resources for the development and display of masculine identity. The aim of this mixed-method study was to examine how "masculine capital" is accrued via traditionally masculine behaviors and used to permit nonmasculine behavior. An online survey assessing personal importance of gender identity, gender role stereotypes, and beliefs about the gender of various health behaviors was completed by 731 university students. Interviews were conducted with a purposive sample of 16 of these men and women. Quantitative data showed significant positive associations between perceived masculinity and engagement in a greater number of traditionally masculine health behaviors. Such patterns were clearest among young men and women who endorsed gender role stereotypes and gave greater importance to their own gender identity. Qualitative data supported the quantitative data: participants with more traditional gender role beliefs had more strict beliefs about the masculinity of various health behaviors. When asked about their own experiences, many men described having engaged in traditionally masculine health-related behaviors so as to accrue masculine capital or use it to permit nonmasculine (or feminine) behavior. The novel use of a gender-relations approach in this mixed-method study of young men and women expanded on earlier smaller scale studies of men and masculine capital. The findings add to understanding of the concept of "masculine capital" and suggest how it may aid efforts to better understand and improve young men's health. Young men's concerns about masculinity could be harnessed to encourage healthy "masculine" behavior. However, such approaches may not be effective for men who eschew traditional definitions of masculinity. Furthermore, failure to question socially constructed definitions of gender may reinforce stereotypes that restrict men's and women's opportunities.

    Headache with normal examinations and imaging, occurring during an airplane flight has been rarely reported. We present a young patient with a new type of headache that appeared during flights: take-off and landing of a plane and was not associated with other conditions. This airplane headache is rather rare in population and the pathophysiology of this type is not clear. Secondary causes must be ruled out before the diagnosis of a primary headache is made.

    A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0.10 ng/mL (normal <0.04 ng/mL). A CT angiogram (CTA) was obtained showing a normal-appearing aorta and no abnormal extracardiac findings. Urgent coronary angiography was performed; images are shown in figure 1A-C.

  16. Telangiectatic osteosarcoma of femur in a young man

    International Nuclear Information System (INIS)

    Mita-Alban, Luis Carlos; Alvarez-Ramirez, Rodrigo; Alvarado-Acosta, Fernando

    2004-01-01

    Telangiectatic osteosarcoma is a rare malignant lesion that is about 2,5 % of all primary osteosarcomas. This osteosarcoma has been associated with a more aggressive course than the conventional osteosarcoma, in large clinical series. By its clinical behavior, radiological and histopathological aspects, it is very similar to other benign tumours, such as aneurysmal bone cyst. A case of a male patient aged 24, healthy, with chronic pain in his left knee as the only symptom is presented. He was diagnosed with this rare form of osteosarcoma and amputated. The patient received a regimen of 6 months of chemotherapy, after which there were found metastases and chest wall. It is important to recognize this variant of osteosarcoma and to differentiate from benign lesions because only resection, treatment, carries a reserved prognosis, while if chemotherapy is added, life expectancy improves. Besides this, also it is important to remember this entity in the differential diagnosis of the painful member in healthy and young people. (author) [es

  17. Subacute neuronopathy in a young man: a possible association with tetracycline treatment

    Directory of Open Access Journals (Sweden)

    Magnus Vrethem

    2011-11-01

    Full Text Available A young man with subacute neuronopathy following tetracycline treatment is described. The symptoms started as a sensory dorsal root affection but by time also involved motor nerves. He developed a severe sensory ataxia with pseudoathetotic movements. Other possible aetiologies were scrutinized and excluded. Tetracycline induced neuronopathy is hitherto not reported in the literature. We propose a possible association between treatment with tetracycline and the development of sensory neuronopathy in this patient.

  18. Haemophilus parainfluenzae Endocarditis Associated With Maxillary Sinusitis and Complicated by Cerebral Emboli in a Young Man

    Directory of Open Access Journals (Sweden)

    Anthony E. Duzenli MD

    2017-04-01

    Full Text Available HACEK endocarditis is often difficult to diagnose given the slow-growing characteristics of the organisms involved. Haemophilus parainfluenzae, one of the HACEK organisms, is an uncommon cause of endocarditis. We describe a case of a previously healthy young man with H parainfluenzae endocarditis that was associated with maxillary sinusitis and severe systemic complications, including septic cerebral emboli and mitral valve perforation. Previously reported cases have also described a predilection for younger people, cardiac valve pathology, and a high prevalence of stroke.

    Pancreatic cancer in young adults is very rare. We report a case of young-onset poorly differentiated pancreatic ductal adenocarcinoma with rapid progression and poor prognosis in a 31-year-old Japanese man with no obvious family history of malignancy. Preoperative examinations revealed a mass lesion in the body of the pancreas, accompanied by a slightly dilated main pancreatic duct distal to the mass lesion. Pancreatic cancer with acute pancreatitis was suspected because of an elevation of serum pancreatic enzyme and tumor marker, along with imaging findings. Distal pancreatectomy with resection of the common hepatic artery and splenectomy along with lymph node dissection was performed. Microscopically, the tumor was mainly composed of poorly differentiated ductal adenocarcinoma. The postoperative course was uneventful, but the patient had multiple liver metastases 2 months postoperatively, in spite of adjuvant chemotherapy, and died 8 months postoperatively. This case may represent a rare instance of young-onset poorly differentiated ductal adenocarcinoma with rapid progression and may indicate potential risk factors of pancreatic cancer in young adults.

    2015-01-01

    Full Text Available Cat scratch disease is a benign clinical syndrome manifested as lymphadenopathy, fever and sometimes with atypical symptom of blurring of vision. It occurs following cat ’s bites or scratches. This case report presented a healthy young man presented with left eye blurring of vision for 1 month duration preceeded by history of recurrent low grade fever with previous history of being scratched by cat. Examination revealed optic disc edema with macula star. Thorough investigations were done and shown positive titre towards Bartonella henselae. He responded well with intravenous ceftazidime, oral doxycycline and rifampicin. His vision improved to 6/9 and 6/6 with pinhole after 3 months.

  1. Corneal arcus: an indicator of severe coronary artery disease in a young adult man.

    Science.gov (United States)

    Sucu, Murat; Davutoglu, Vedat

    2009-01-01

    A 32-year-old man was transferred to our emergency service with the diagnosis of sudden cardiopulmonary arrest. During eye examination, a typical corneal arcus was observed. The patient underwent the primary percutaneous coronary intervention. Coronary angiography showed a total occlusion of proximal left anterior descending artery. Primary coronary balloon angioplasty was successfully performed. Independently of total cholesterol, serum high-density lipoprotein cholesterol and smoking, corneal arcus has been suggested as a predictor of coronary heart disease among hyperlipidemic men. Physical examination can yield valuable diagnostic clues in a patient suspected of ischaemic heart disease. In summary, the appearance of corneal arcus in young adult men might be an indicator of severe coronary artery disease and should be screened by means of physical examination especially in the setting of cardiopulmonary arrest (Fig. 1, Ref. 4).

    Dietary supplementation of arginine has been used by numerous world-class athletes and professional bodybuilders over the past 30 years. L-Arginine indeed enhances muscular power and general performance via maintaining ATP level. However, L-arginine is also known to induce acute pancreatitis in murine models. We report the case of young man presenting with upper abdominal pain and increased serum lipase levels. Contrast-enhanced computed tomography confirms a mild acute pancreatitis. Common etiologies have been ruled out and toxicological anamnestic screening reveals the intake of protein powder. This is, to the best of our knowledge, the second case in human of arginine-induced acute pancreatitis. This case report suggests that every patient presenting with acute pancreatitis without obvious etiology should be evaluated for the intake of toxics other than alcohol, including L-arginine.

  3. Actinomyces graevenitzii Pulmonary Abscess Mimicking Tuberculosis in a Healthy Young Man

    Directory of Open Access Journals (Sweden)

    Smaranda Gliga

    2014-01-01

    Full Text Available Pulmonary actinomycosis is a rare disease that is often misdiag-nosed as tuberculosis or lung cancer. Actinomyces graevenitzii is a relatively new recognized Actinomyces species isolated from various clinical samples. The authors report a case of pulmonary actinomycosis caused by A graevenitzii. A computed tomography examination revealed an excavated consolidation in the middle right lobe of a previously healthy young man who presented with a long history of moderate cough. Cultures of the bronchoalveolar lavage fluid confirmed the diagnosis of pulmonary abscess caused by A gravenitzii. At the three-month follow-up consultation and, after six weeks of high-dose amoxicillin, the pulmonary lesion had completely disappeared.

    2011-08-01

    We present the case of an 18-year-old man, previously healthy, who presented with acute quadriplegia and respiratory failure. Physical examination was compatible with a high cervical anterior spinal cord lesion. We plan to evaluate the cause of such a neurological presentation in a healthy young man. American University Medical Center, Beirut, Lebanon. The patient underwent routine blood hematological and chemistry work-up, hypercoagulable profile studies, genetic profile for thrombophelias, radiographic studies of the brain and cervical cord, cerebrospinal analysis and extensive electrophyisological studies. Magnetic resonance imaging and magnetic resonance angiogram of the brain, carotid and intracranial vessels were normal. Cerebral angiography was normal. Magnetic resonance imaging of the cervical cord revealed lesion of the anterior segment of the cervical cord between C2 and C5 levels. Hypercoagulable profile studies were normal. Electrophysiological studies confirmed an isolated lesion of the descending cortico-spinal tracts. DNA analysis revealed the presence of a G20210A mutation-causing hyperprothrombinemia. We conclude that a G20210A mutation causing-hyperprothrombinemia can cause anterior spinal artery thrombosis and anterior spinal cord infarction with the resultant neurological deficits in otherwise healthy patients.

  5. Prostatic stromal tumor with fatal outcome in a young man: histopathological and immunohistochemical case presentation

    Directory of Open Access Journals (Sweden)

    Piergiuseppe Colombo

    2010-10-01

    Full Text Available Stromal tumors of the prostate are rare and only a few cases have been described in the literature, including exceptional cases of stromal tumors with unknown malignant potential (STUMP and a fatal outcome in young patients. Morphologically distinguishing a STUMP from a stromal sarcoma of the prostate (PSS is still a challenge. We describe the histopathological and immunohistochemical findings in a 34-year-old man with a malignant specialized cell stromal tumor of the prostate that was diagnosed initially as STUMP, and he developed lung metastases within a few months. The patient attended our hospital because of lower urinary tract symptoms, after having excreted tissue through the urethra a few months before. Ultrasonography and urethrocystoscopy examinations showed a mass arising from the verumontanum, and a transurethral resection (TUR revealed a high-grade spindle cell sarcoma reminiscent of a phyllode tumor of the breast. The tumor cells were immunoreactive for vimentin, progesterone receptor and, focally, CD34. The preliminary histo­logical findings were subsequently confirmed after radical prostatectomy. The patient developed bilateral lung metastases and died 25 months after the initial diagnosis. Although rare in young patients, the challenging differential diagnosis of STUMP and PSS means that a prostate STUMP diagnosis made on the basis of biopsy or TUR specimens also requires urethrocystoscopic monitoring for the early detection of any progression to PSS. Radical prostatectomy should also be carefully considered.

    Miller, S.C.

    1985-01-01

    The overall objective of this research program is to predict the risk to humans following exposure to 239 Pu. The beagle was originally selected for this program because it is relatively long-lived and has skeletal functions and structure analogous to young adults humans, simulating that of a young adult radium dial painter or occupationally exposed person. Young adult (17 month-old) beagles from the moderately inbred colony at the University of Utah were administered one intravenous injection of 239 Pu (0.0007-2.88 μCi/kg in 238 dogs) or 226 Ra (0.007-10.4 μCi/kg in 119 dogs), and compared to appropriate age-matched control beagles. All beagles have been and are being observed clinically throughout their expected 12 to 15 year post-injection lifespan. A thorough clinical and post-mortem survey is conducted to determine causes of death or lesions at death. The clinical findings are being encoded using SNOMED terminology and entered into a computerized database. All beagles in the 226 Ra study are dead and the data are being analyzed and published. The shape of the curve for dose vs. bone tumor incidence is highly linear up to average skeletal doses of 2200 rads. In higher dose groups, the time to tumor appearance is decreased and skeletal tumors occur in almost all animals. The 226 Ra response is being compared with the 239 Pu response in beagles. This toxicity ratio will allow use of the bone tumor response in the radium dial painters to predict the toxicity of plutonium for bone tumor induction in man

  10. Growing up as "man of the house": adultification and transition into adulthood for young men in economically disadvantaged families.

    2014-03-01

    Many children in economically disadvantaged communities assume adult roles in their families. Negotiating the responsibilities and expectations associated with becoming what some young men describe as "man of the house" has important implications for how adolescent boys move into adulthood. In this study, we share insights from field work and life-history interviews with low-income, young African American men and Salvadoran men in the Washington, DC/Baltimore region to illustrate how adultification may deliver contradictory expectations for adolescents. The findings also show how the accelerated responsibilities that accompany the experience of adultification create difficulties in the young men's transition into adulthood. These findings indicate that the age period of emerging adulthood may begin earlier for economically disadvantaged young men. © 2014 Wiley Periodicals, Inc.

    Full Text Available A Portrait of the Artist as a Young Man, written in 1916, is an authobiography and the first novel of the great Irish writer, James Joyce. It's written in Modernist style. So it can be contain of some category of realism, naturalism, and Marxism which aroused in mid-to late nineteenth century. But it mostly included realistic style because of the begining date of this literary school. By reading all works of James Joyce is maybe committing ownself to a  outstanding trickary world of  "chaosmos" (Finnegans Wake, p. 118.21, which stands for poetic mystery that few writers have acheived. In this study attempted is made to survey the main Protagonist in A Portrait of the Artist as a Young Man, and Ulysses, Stephen Dedalus, and its relationship to the author.

    A Portrait of the Artist as a Young Man is the first novel of stream of consciousness in western literature history, it mainly shows the protagonist, Stephen Dedalus's journeys from childhood to adulthood. This paper aims at a better understand-ing of Stephen Dedalus, and it analyzes his character traits in literature analysis method, textual analysis method and Freud's theory of personality structure and is useful for further study.

  13. Studying A Portrait of the Artist as a Young Man through Heterogeneous Philosophy of Georges Bataille

    Directory of Open Access Journals (Sweden)

    Shataw Naseri

    2014-09-01

    Full Text Available Georges Bataille believes that most of his contemporary discourses were spiritual and/or intellectual ones. They were, for him, vegetation-like discourses looking upward and underlining the role of head and thinking in their paradigms. He, instead, introduced the notion of "base materialism" which highlights the role of the lower parts of the body; it is here that Bataille raises the notion of "Acéphale" who has beheaded himself with a dagger in his right hand, and thus has beheaded the ruling head of his own body as well as the heads of his surrounding social discourses. For George Bataille, humans are linguistic being entrapped forever in a language system. However, he believes that this system is full of fissures and that through transgressive moments one can experience these voids within language. Through transgression one can look directly in the abyss of language, though he/she cannot see the extremity of these voids and thus Bataille believes that one cannot reach any signified, and therefore, any Bataillean "Impossible." As one can witness, linguistic human being is entrapped within narratives of language system defining him in terms of cause and effect and their related items namely linear time and space. Georges Bataille believes that any heterogeneous element which crosses the defined taboos of the body of self and society at some transgressive moments is regarded as a "foreign body" and an "alterity." This foreign body, as he regards, at the instants of transgression experiences "sovereignty" which means that he is at the epic of being a "sovereign being," of course momentarily, because he at those moments has stepped upon any ruling borders and is bound with no taboo and thus is the "sovereign" of instants. The present study endeavors to analyze Stephen Dedalus in A Portrait of the Artist as a Young Man and his Bataillean experiences in terms of narrative and language. A Portrait will be concentrated in the light of the

    Although tragic, the plight of Terri Schiavo provides a valuable case study. The conflicts and misunderstandings surrounding her situation offer important lessons in medicine, law, and ethics. Despite media saturation and intense public interest, widespread confusion lingers regarding the diagnosis of persistent vegetative state, the judicial processes involved, and the appropriateness of the ethical framework used by those entrusted with Terri Schiavo's care. First, the authors review the current medical understanding of persistent vegetative state, including the requirements for patient examination, the differential diagnosis, and the practice guidelines of the American Academy of Neurology regarding artificial nutrition and hydration for patients with this diagnosis. Second, they examine the legal history, including the 2000 trial, the 2002 evidentiary hearing, and the subsequent appeals. The authors argue that the law did not fail Terri Schiavo, but produced the highest-quality evidence and provided the most judicial review of any end-of-life guardianship case in U.S. history. Third, they review alternative ethical frameworks for understanding the Terri Schiavo case and contend that the principle of respect for autonomy is paramount in this case and in similar cases. Far from being unusual, the manner in which Terri Schiavo's case was reviewed and the basis for the decision reflect a broad medical, legal, and ethical consensus. Greater clarity regarding the persistent vegetative state, less apprehension of the presumed mysteries of legal proceedings, and greater appreciation of the ethical principles at work are the chief benefits obtained from studying this provocative case.

    Articles from many of the main contributors to recent progress in stochastic analysis are included in this volume, which provides a snapshot of the current state of the area and its ongoing developments. It constitutes the proceedings of the conference on "Stochastic Analysis and Applications" held at the University of Oxford and the Oxford-Man Institute during 23-27 September, 2013. The conference honored the 60th birthday of Professor Terry Lyons FLSW FRSE FRS, Wallis Professor of Mathematics, University of Oxford. Terry Lyons is one of the leaders in the field of stochastic analysis. His introduction of the notion of rough paths has revolutionized the field, both in theory and in practice.  Stochastic Analysis is the branch of mathematics that deals with the analysis of dynamical systems affected by noise. It emerged as a core area of mathematics in the late 20th century and has subsequently developed into an important theory with a wide range of powerful and novel tools, and with impressive applications ...

    Young adult (YA) dystopia, a genre which is led almost exclusively by young female protagonists, has gained much scholarly attention in recent years. While most of the academic discussions focus, rightly, on portrayals of female characters and gender performance, portrayals of masculinity have failed to elicit the same scholarly response. This…

    O'Neill, E C

    2012-02-01

    BACKGROUND: Cranial nerve palsies has several etiologies including vascular insufficiency, neoplasm, trauma and inflammation. Isolated sixth nerve palsy is an extremely rare presenting feature of leukemia. AIM: We describe an unusual ocular presentation of a bilateral progressive sixth nerve palsy in a young male with a preceding head injury. CONCLUSION: Acquired sixth nerve palsies in young adults may be due to trauma but in the absence of a definitive history other systemic processes must be outruled. We describe a case of bilateral sixth nerve palsy in a patient with ALL with no obvious CNS involvement. Potential etiological mechanisms are discussed.

    We describe a case of exercise-induced acute compartment syndrome (ACS) in a 23-year-old man who presented to his primary care physician 48 hours after he attempted to run a 5K race. He noticed searing pain in his left leg after the first half mile but had no other symptoms. He was referred to the emergency department and diagnosed with ACS, and a fasciotomy was done. A presentation of limb pain that is out of proportion to a known or suspected injury should prompt consideration of ACS. Early recognition and surgical management are essential to achieving the best possible outcome.

    2013-11-05

    A 21-year-old man presented with headache, hypotonia, hypothermia, and somnolence, deteriorating to a Glasgow Coma Scale score of 3 within days. Hormonal testing revealed panhypopituitarism. His cerebral MRI showed a gadolinium-enhancing lesion in the pituitary gland with adjacent changes to the hypothalamus, midbrain, and basal ganglia (figures 1 and 2). Therapy with prednisolone resulted in rapid improvement. Ma2 antibodies were found in the patient's serum and CSF. FDG-PET demonstrated a tumor mass in the superior mediastinum and histology revealed a mediastinal seminoma. Ma2 antibody-mediated paraneoplastic disease has to be considered as a rare differential diagnosis in patients presenting with acute panhypopituitarism.(1.)

    Full Text Available Abstract Introduction Autonomic innervation of the bladder is complex and regulated by a hierarchy of mechanisms of the central nervous system. Any dysfunction in these regulatory mechanisms can lead to acute urinary retention. Case presentation A 36-year-old Caucasian man presented with acute urinary retention following extensive bowel irrigation. His urinary bladder was decompressed and his normal voiding mechanism was restored thereafter. Conclusion We postulate that prolonged anorectal and sigmoid dilatation can stimulate the recto-vesicourethral reflex and lead to acute urinary retention via autonomic dysfunction.

    Abdominal aortic aneurysms (AAAs) are very rare in Marfan syndrome. We present a case with a young nonsmoking and normotensive male with Marfan syndrome, who developed an infrarenal AAA that presented with rupture to the retroperitoneal cavity causing life-threatening bleeding shock. The patient had acute aortic surgery and survived. Five months before this incident, the patient had uneventful elective aortic root replacement (ad modum David) due to an enlarged aortic root. At that time, his abdominal aorta was assessed with a routine ultrasound scan that showed a normal-sized abdominal aorta. This documents that the aneurysm had evolved very rapidly despite young age and absence of risk factors. Copyright © 2018 Elsevier Inc. All rights reserved.

    We report the case of a 20-year-old man with a 2-month history of anal pain and bloody rectal discharge. He was referred to our clinic of gastroenterology for suspected inflammatory bowel disease (IBD). The colonoscopy showed mucosal nodularities on the rectum and an anal tag. Because the colonoscopic findings were not consistent with the typical manifestations of IBD, we took an additional sexual history and performed studies for infectious proctitis, including serologic tests for Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum. He had homosexual experience, and the serologic tests and PCR of a rectal swab were positive for C. trachomatis infection. Finally he was diagnosed as having chlamydial proctitis and was treated with intramuscular ceftriaxone 250 mg in a single dose and doxycycline 100 mg orally twice daily for 7 days. After 2 months, he had no lower abdominal symptoms and his endoscopic findings were improved.

    Although Plasmodium ovale is considered the cause of only mild malaria, a case of severe malaria due to P. ovale with acute respiratory distress syndrome is reported. A 37-year old Caucasian man returning home from Angola was admitted for ovale malaria to the National Institute for Infectious Diseases Lazzaro Spallanzani in Rome, Italy. Two days after initiation of oral chloroquine treatment, an acute respiratory distress syndrome was diagnosed through chest X-ray and chest CT scan with intravenous contrast. Intravenous artesunate and oral doxycycline were started and he made a full recovery. Ovale malaria is usually considered a tropical infectious disease associated with low morbidity and mortality. However, severe disease and death have occasionally been reported. In this case clinical failure of oral chloroquine treatment with clinical progression towards acute respiratory distress syndrome is described.

    Anabolic androgenic steroid (AAS) abuse has increased among athletes in recent years. However, AAS abuse can increase hypercoagulopathy and cause cerebrovascular disease. We report a case of a 27-year-old man who had right hemiparalysis, hemianopia, dysarthria, and double vision in the middle of muscle training. He suspected acute disseminated encephalomyelitis at first, because of a preceding respiratory infection. However, extensive work-up was performed, including brain magnetic resonance imaging, transcranial Doppler and transesophageal echocardiography, confirming the final diagnosis of cardioembolic stroke. Physicians should be aware that cerebrovascular disease may be a side effect of AAS, even in younger populations. Copyright © 2012 National Stroke Association. Published by Elsevier Inc.

    2007-12-01

    In this paper, a novel ARM-based mechatronics control technique applied in terry rapier loom was presented. Electronic weft selection, electronic fluff, electronic let-off and take-up motions system, which consists of position and speedcontrolled servomechanisms, were studied. The control system configuration, operation principle, and mathematical models of electronic drives system were analyzed. The synchronism among all mechanical motions and an improved intelligent control algorithm for the warp let-off tension control was discussed. The result indict that, by applying electronic and embedded control techniques and the individual servomechanisms, the electronic weft selection, electronic let-off device and electronic take-up device in HGA732T terry rapier loom have greatly simplified the initial complicated mechanism, kept the warp tension constant from full to empty beam, set the variable weft density, eliminated the start mark effectively, promoted its flexibility, reliability and properties, and improved the fabric quality.

    2007-01-01

    This book is a compilation of 12 reports presented at the St-Ursanne workshop. The workshop was dedicated to the scientific community of the Mont Terri partner organisations, their management and scientific/technical staff, involved research organisations and key contractors. The purpose of the event was to acknowledge the excellent research work that has been performed over the last decade, to evaluate and discuss the present state of knowledge in selected research areas and to explore the potential for future research activities. The topical areas addressed in the workshop are of particular importance with regard to deep geological disposal of radioactive waste and focused on the issues of coupled phenomena and transport processes in argillaceous rock and the demonstration (in underground rock laboratories) of disposal feasibility. After showing the history of the Mont Terri project and the general geology of Northwestern Switzerland, the different presentations are distributed into 3 topics: (a) Coupled phenomena in argillaceous rock, (b) Transport processes in argillaceous rock, and (c) Demonstration of disposal feasibility in underground rock laboratories. The last chapter describes the research still needed and the Mont Terri rock laboratory

    Male adolescents and young men benefit when their mental health care is specialized to match their unique gendered and developmental needs. Sensitivity to the social circumstances of this population is important; additionally, the emerging ability to tailor care through knowledge gleaned from the intersection of psychiatry, neurology, and endocrinology informs care. This article summarized the views of six experts in the area of the adolescent and young adult male mental health. These experts were select members of the World Federation of Societies of Biological Psychiatry's Task Force on Men's Mental Health. They convened to present two symposia on the topic of men's mental health at the 13th World Congress of Biological Psychiatry (WCBP) in Copenhagen, Denmark in 2017. In these works, a special focus is paid to addictive disorders, disruptive behavior disorders, aggression, and brain development. Collectively, the authors present an argument for the merits of a male-specific model of mental health care to advance the overall well-being of this population. Men's mental health should be recognized as a social issue as much as a medical issue, with special attention paid to problems such as unemployment, familial disruption, and substance abuse. These problems, and especially those of major societal impact including violence and suicide which are much more frequently the product of male youth and men, should have more male-tailored options for service provision that respond to men's mental health needs.

    A 34-year-old man presented to a hospital with a 7-day history of nausea, vertigo, ataxia and frontal headache. Examination revealed ipsilateral cerebellar signs. CT of the brain demonstrated left cerebellar hypodensity suggestive of ischaemic stroke or space occupying lesion. Full blood count showed a markedly raised haemoglobin (219 g/L) and haematocrit (0.56). Admission urinalysis was performed but the results not reviewed. Owing to patient deterioration, an arterial blood gas was performed. This showed profound metabolic acidosis. Repeat urinalysis was positive for glucose and ketones. MRI of the brain confirmed ischaemic stroke. The underlying cause of this was hyperviscosity secondary to relative polycythaemia, resulting from undiagnosed diabetic ketoacidosis as a first presentation of diabetes. This case report highlights ischaemic stroke as an unusual presenting feature of diabetic ketoacidosis. Notably, the underlying diagnosis of diabetic ketoacidosis was initially missed, thereby emphasising the importance of performing an admission urinalysis and acting on the results. 2014 BMJ Publishing Group Ltd.

  11. A young man with hemoptysis: Rare association of idiopathic pulmonary hemosiderosis, celiac disease and dilated cardiomyopathy

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare cause of recurrent diffuse alveolar hemorrhage (DAH with no specific treatment. Herein, we discuss a case of hemoptysis, who had IPH and other rare associations. A 19-year-old man presented with recurrent hemoptysis, generalized weakness and progressive dyspnea for 3 years. Earlier, he was diagnosed with anemia and was treated with blood transfusions and hematinics. On examination he had pallor, tachycardia and was underweight. Investigations revealed low level of hemoglobin (7.8 g/dl and iron deficiency. An electrocardiography (ECG showed sinus tachycardia, interventricular conduction delay and T-wave inversion. Echocardiography revealed dilated cardiomyopathy with left ventricular dysfunction. Computed tomography of the chest demonstrated bilateral diffuse ground glass opacity suggestive of pulmonary hemorrhage. Pulmonary function tests showed restrictive pattern with increased carbon monoxide diffusion. Bronchoalveolar lavage and transbronchial lung biopsy showed hemosiderin-laden macrophages. Patient could recall recurrent episodes of diarrhea in childhood. Serum antitissue transglutamase antibodies were raised (291.66 IU/ml, normal <30 IU/ml. Duodenal biopsy showed subtotal villous atrophy consistent with celiac disease. He was started on gluten-free diet, beta blockers and diuretics. After two years of treatment, he has been showing consistent improvement. Screening for CD is important in patients with IPH. Cardiomyopathy forms rare third association. All three show improvement with gluten-free diet.

    Full Text Available Objective. To report a case of refractory status epilepticus (SE as an unusual early manifestation of H1N1 influenza infection. Introduction. H1N1 neurological complications have been reported and consist mainly of seizures or encephalopathy occurring in children. However, we only found a single report of an adult developing complex partial SE with H1N1 infection. Case Report. A 21-year-old previously healthy man was brought to the emergency room (ER after a witnessed generalized tonic clonic seizure (GTCS. He was fully alert and afebrile upon ER arrival, but a second GTCS prompted treatment with Lorazepam and Fosphenytoin. The initial EEG showed diffuse slowing, but a repeat one requested as the patient failed to regain consciousness revealed recurrent focal seizures of independent bihemispheric origin, fulfilling the criteria for nonconvulsive SE. Chest X-ray, followed by chest CT scan, showed a left upper lobe consolidation. H1N1 infection was confirmed with PCR on bronchoalveolar lavage material. Despite aggressive treatment with Midazolam, Propofol, and multiple high dose antiepileptic drugs, the electrographic seizures recurred at every attempt to reduce the intravenous sedative drugs. The patient died two weeks after his initial presentation. Conclusion. H1N1 should be added to the list of rare causes of refractory SE, regardless of the patient’s age.

    Full Text Available Although osteoporosis is defined as being a painless and progressive condition, one special subtype of osteoporosis is reversible and painful. Because it isn’t permanent and is obvious in the hip joint, this condition is called transient osteoporosis of the hip. Typically, the paitents are women in the third trimester of pregnancy and middle-aged men who are seen initially with acute progressive pain, antalgic gait, and severe functional disability involving the affected extremity. Its aetiology remains a matter of speculation, and the same remains true for its treatment. Many researchers have proposed different surgical and non-surgical treatment strategies; but the conservative approach, which takes the form of analgesics, intermittent traction, range of motion exercises, abductor strengthening exercises and restricted weight bearing, is preferred. In this paper we report a 22 years old man with transient osteoporosis of the hip who showed excellent recovery following a conservative approach. (From the World of Osteoporosis 2008;14:35-9

  14. Two Metachronous Neoplasms in the Radiotherapy Fields of a Young Man With Familial Adenomatous Polyposis

    Patrick A. Williams BS

    2013-04-01

    Full Text Available Background: It is recognized that various radiation-induced malignancies often follow childhood radiotherapy. Radiation-induced neoplasms have been shown to occur with increased frequency in syndromes due to mutated tumor suppressor genes. There exist no recommendations for the management of cancer patients with germline APC gene mutations. Preclinical data suggest that APC gene mutations cause enhanced radiosensitivity, but no clinical observations exist that show that patients with this mutation are at higher risk for radiation-induced malignancies. Results: We report the case of a 32-year-old man with a genetic diagnosis of familial adenomatous polyposis (FAP who initially presented at age 10 with a medulloblastoma treated with radiotherapy and surgery. Radiation-induced papillary thyroid carcinoma followed 13 years later. Finally, radiation-induced soft tissue osteosarcoma occurred with widespread metastasis 20 years thereafter. Conclusions: This is the first report of 2 malignancies in the prior radiotherapy fields of a patient with a genetic diagnosis of FAP. More important, this suggests that APC-defective cells are at an enhanced sensitivity to the carcinogenic effects of radiotherapy compared with APC-proficient cells. This could argue for genetic screening in affected members of these families and for creation of treatment recommendations to more seriously consider the risks of radiation therapy.

  15. Spontaneous Acute Mesenteroaxial Gastric Volvulus Diagnosed by Computed Tomography Scan in a Young Man.

    2016-04-26

    Acute gastric volvulus is a surgical emergency that requires early recognition and treatment. Acute idiopathic mesenteroaxial gastric volvulus is a rare sub-type and there are few cases reported in children and there are even fewer reports in adults. We report a rare case of a 23-year-old man who presented with a 1-day history of vomiting, epigastric pain, distention, and constipation. The diagnosis for mesenteroaxial type gastric volvulus was confirmed by abdominal radiography and computed tomography. The patient was successfully treated by laparotomy with resection of the ischemic stomach wall and anastomosis. Acute spontaneous mesenteroaxial gastric volvulus is rare in adults and early diagnosis is challenging due to non-specific symptoms. A missed or delayed diagnosis may result in serious complications due to gastric obstruction. A patient presenting with severe epigastric pain and clinical evidence of gastric outlet obstruction should be considered as a surgical emergency to rule out gastric volvulus. High index of suspicion, early diagnosis and prompt surgical management are important for favorable outcome in patients with acute spontaneous gastric volvulus.

    2014-03-01

    Full Text Available Over the four decades, a significant decrease has been observed in age-related mortality caused by cardiovascular disease. People in developing countries suffer from CAD at a relatively younger age and about half of MI occurs under the age of fifty years. Abuse of anabolic steroids is one of the less common causes of atherosclerosis. In this report, a 23-year-old body builder male referred to emergency department (ED with myocardial infarction (MI following chronic Trenbolone acetate consumption. It seems that a comprehensive history of steroid consumption in young patients referred to ED with the chief complaint of chest pain or its equivalents is necessary in adjunct to other cardiac risk factors.

    Carrasco Cubero, Carmen; Chamizo Carmona, Eugenio

    Systemic mastocytosis (SM) is a clonal disease of mast cell progenitors from the bone marrow. The clinical picture varies from asymptomatic forms (indolent) to a highly aggressive form with a very short (mast cell leukemia) survival. Between 28-34% of patients with SM are related to bone condition at the time of diagnosis and 16% have symptomatic fractures. The presentation of SM as clinical vertebral fractures in young men is rare. Here, we describe a case of established osteoporosis as the only manifestation of SM.

  18. SINGLE PHASE ANALYTICAL MODELS FOR TERRY TURBINE NOZZLE

    Energy Technology Data Exchange (ETDEWEB)

    Zhao, Haihua; Zhang, Hongbin; Zou, Ling; O' Brien, James

    2016-11-01

    All BWR RCIC (Reactor Core Isolation Cooling) systems and PWR AFW (Auxiliary Feed Water) systems use Terry turbine, which is composed of the wheel with turbine buckets and several groups of fixed nozzles and reversing chambers inside the turbine casing. The inlet steam is accelerated through the turbine nozzle and impacts on the wheel buckets, generating work to drive the RCIC pump. As part of the efforts to understand the unexpected “self-regulating” mode of the RCIC systems in Fukushima accidents and extend BWR RCIC and PWR AFW operational range and flexibility, mechanistic models for the Terry turbine, based on Sandia National Laboratories’ original work, has been developed and implemented in the RELAP-7 code to simulate the RCIC system. RELAP-7 is a new reactor system code currently under development with the funding support from U.S. Department of Energy. The RELAP-7 code is a fully implicit code and the preconditioned Jacobian-free Newton-Krylov (JFNK) method is used to solve the discretized nonlinear system. This paper presents a set of analytical models for simulating the flow through the Terry turbine nozzles when inlet fluid is pure steam. The implementation of the models into RELAP-7 will be briefly discussed. In the Sandia model, the turbine bucket inlet velocity is provided according to a reduced-order model, which was obtained from a large number of CFD simulations. In this work, we propose an alternative method, using an under-expanded jet model to obtain the velocity and thermodynamic conditions for the turbine bucket inlet. The models include both adiabatic expansion process inside the nozzle and free expansion process out of the nozzle to reach the ambient pressure. The combined models are able to predict the steam mass flow rate and supersonic velocity to the Terry turbine bucket entrance, which are the necessary input conditions for the Terry Turbine rotor model. The nozzle analytical models were validated with experimental data and

    Clindamycin is used to treat various bacterial infections, but its administration can cause anaphylaxis, liver reactions, pseudomembranous colitis, and peripheral blood cytopenias (anemia, neutropenia, and thrombocytopenia), alone or in combination. We report the case of a patient with a recurrent infection of the tonsils who received clindamycin. Pancytopenia, a previously unreported hematological disorder related to clindamycin use, was observed in conjunction with the infection and clindamycin treatment. One month prior to hospitalization, a 22-year-old man of Hispanic origin had a tonsillar infection and cough and began to have anal pain. These conditions became exacerbated three weeks later, coinciding with a new tonsillar infection, frequent nonproductive cough, and febrile syndrome. He received clindamycin for four days prior to his admission, without improvement. While hospitalized, he was found to have fever, tonsillar abscess, hemorrhoid thrombosis, and anal fissure; the latter was immediately resected under general anesthesia. Before surgery, our patient's blood count showed intense leukoneutropenia and mild thrombocytopenia that increased 12 hours later, along with the establishment of anemia. A bone marrow study showed decreased cell content, micromegakaryocytes, and an interruption of the differentiation of granulocytes and erythroblasts. Post-surgery, our patient received metronidazole, meropenem, and amikacin along with acetaminophen, ketoprofen, omeprazole, and pegfilgrastim, with resulting clinical and hematological improvement. Our experience with this patient establishes that well-documented clinical cases should be the basis for identifying and publicizing unknown or uncommon undesirable effects of drugs. We report that, in some individuals, clindamycin can cause pancytopenia, a complication that in our patient's case was caused by direct injury of his hematopoietic tissue.

  20. Masculinities, 'guy talk' and 'manning up': a discourse analysis of how young men talk about sexual health.

    Sexually transmitted infection testing rates among young men remain low, and their disengagement from sexual health services has been linked to enactments of masculinity that prohibit or truncate discussions of sexual health. Understanding how men align with multiple masculinities is therefore important for tailoring interventions that appropriately respond to their needs. We draw on 32 in-depth interviews with 15-24-year-old men to explore the discourses that facilitate or shut down sexual health communication with peers and sex partners. We employ a critical discourse analysis to explore how men's conversations about sexual health are constituted by masculine hierarchies (such as the ways in which masculinities influence men's ability to construct or challenge and contest dominant discourses about sexual health). Men's conversations about sexual health focused primarily around their sexual encounters - something frequently referred to as 'guy talk'. Also described were situations whereby participants employed a discourse of 'manning up' to (i) exert power over others with disregard for potential repercussions and (ii) deploy power to affirm and reify their own hyper-masculine identities, while using their personal (masculine) power to help others (who are subordinate in the social ordering of men). By better understanding how masculine discourses are employed by men, their sexual health needs can be advanced. © 2012 The Authors.

    Antithrombin and protein C are two crucial members in the anticoagulant system and play important roles in hemostasis. Mutations in SERPINC1 and PROC lead to deficiency or dysfunction of the two proteins, which could result in venous thromboembolism (VTE). Here, we report a Chinese 22-year-old young man who developed recurrent and serious VTE in cerebral veins, visceral veins, and deep veins of the lower extremity. Laboratory tests and direct sequencing of PROC and SERPINC1 were conducted for the patient and his family members. Coagulation tests revealed that the patient presented type I antithrombin deficiency combined with decreased protein C activity resulting from a small insertion mutation c.848_849insGATGT in SERPINC1 and a short deletion variant c.572_574delAGA in PROC. This combination of the two mutations was absent in 400 healthy subjects each from southern and northern China. Then, we summarized all the mutations of the SERPINC1 and PROC gene reported in the Chinese Han population. This study demonstrates that the combination of antithrombin deficiency and decreased protein C activity can result in severe VTE and that the coexistence of different genetic factors may increase the risk of VTE.

    This article contributes to a more systematic understanding of the role of mainstream media in deliberative processes by analyzing how inclusive local newspapers are of diverse perspectives on the Terri Schiavo case. Using both Pearson's chi-square test and multinomial logistic regression, we assess how ownership, state political ideology, geographic location, and news format affect what ideas are included in the debate over whether Terri Schiavo's hydration and nutrition tubes should be removed as well as the tone with which these ideas are discussed. We find that mainstream newspapers are relatively inclusive of diverse ideas and perspectives-regardless of whether the newspaper is independently or corporately owned, the political leanings of the target audience, and the geographic location of the outlet. However, we also find that local newspapers do significantly differ from one another in terms of the frequency and tone with which they include diverse viewpoints. Our research suggests that local outlets downplay ideas that are likely to be regarded as controversial by their target audiences. We conclude with a discussion of the implications of this research for understanding the role of media in deliberative democratic processes in the United States.

    A Künstlerroman is a literary genre that focuses on the psychological and moral growth of the protagonist from youth to adulthood, and in which character change is thus extremely important. A portrait of the artist as a young man as a Künstlerro-man also shows the growth process of the protagonist from childhood to youth. The paper aims to point out the growth process of the protagonist focusing on the text. Especially, from the two aspects:content and form. The content and the form together re-flect the growth process of the protagonist and the development of his personality, so we also see the protagonist was destined to be mature and at last decided to escape his home, exile himself and began his new life with the purpose of art.

    Students with profound intellectual disabilities disorders (IDDs) have the right to participate in educational opportunities that recognize their unique resources and needs, as do all children. Because of their specific communication challenges, positive relationships with attentive communication partners are critical for success. In fact, the power of positive relationships in schools is recognized to be connected to student well-being more broadly. This article examines the case of one young man with profound IDD and his relationship with his music therapist using a duo-ethnographic informed paradigmatic case study. Video analysis based on multi-voice perspectives is used to generate hermeneutic phenomenological findings to closely examine the relationship between a young man with profound IDD and a music therapist. The voices of four allied health researchers were also gathered to inform the authors’ construction of an informed commentary on the phenomenon. The results suggest that the essence lay in a combination of attentive, responsive and creative being with the other person over time. Four principles of musical engagement were identified in the video footage as critical to the meaningful relationships through music: the music therapist listens; the music therapist takes responsibility for structure; spontaneous initiation is sought from the young person; and the relationship is built over time. These concepts are contextualized within a discussion of student well-being that is underpinned by positive relationships and leads to students achieving their full potential within diverse school contexts.

    This article examines media discourse surrounding the Chelsea and England footballer John Terry and argues that his iconicity embodies multiple anxieties about Englishness and English football in the era of neoliberalism. In a nostalgic culture in search of ‘traditional’ English heroes, Terry is celebrated for his physicality and traditionally ‘English’ style of play; yet, his off-field behaviour is seen to be both emblematic and symptomatic of a celebrity culture considered to betray the val...

  10. Biopolitics, Terri Schiavo, and the sovereign subject of death.

    2008-12-01

    Humanity does not gradually progress from combat to combat until it arrives at universal reciprocity, where the rule of law finally replaces warfare; humanity installs each of its violences in a system of rules and thus proceeds from domination to domination. (Foucault, 1984, 85) In this essay, I take a note from Michel Foucault regarding the notion of biopolitics. For Foucault, biopolitics has both repressive and constitutive properties. Foucault's claim is that with the rise of modern government, the state became exceedingly concerned about the body politic, the bodies that make up the polis, including the health of those bodies. However, Giorgio Agamben claims that Foucault and all western political philosophy misses the relationship between power and Sovereignty, with disastrous results and totalizing tendencies. I explore the case of Terri Schiavo claiming that the social conservatives have attempted to politicize bare life in its legal maneuverings, but I also show how the social liberals open an uncontrollable space between life and death. Both the left and the right miss the aporia at the heart of western political philosophy, and bioethics is complicit in the totalizing effects of contemporary medicine.

    Document available in extended abstract form only. Shrinkage structures in the Opalinus Clay, related to seasonal changes in temperature and humidity, are observed on the tunnel walls of the Mont Terri Rock Laboratory. The structures open in winter, when relative humidity in the tunnel decreases to 65%. In summer the cracks close again because of the increase in the clay volume when higher humidity causes rock swelling. Shrinkage structures are monitored in the Mont Terri Rock Laboratory at two different sites within the undisturbed rock matrix and a major fault zone. The relative movements of the rock on both sides of the cracks are monitored in three directions and compared to the fluctuations in ambient relative humidity and temperature. The cyclic deformations (CD) experiment aims to quantify the variations in crack opening in relation to the evolution of climatic conditions and to identify the processes underlying these swell and shrinkage cycles. It consists of the following tasks: - Measuring and quantifying the long-term (now up to three yearly cycles) opening and closing and, if present, the associated shear displacements of selected shrinkage cracks along an undisturbed bedding plane as well as within a major fault zone ('Main Fault'). The measurements are accompanied by temperature and humidity records as well as by a long-term monitoring of tunnel convergence. - Analysing at the micro-scale the surfaces of the crack planes to identify potential relative movements, changes in the rock fabric on the crack surfaces and the formation of fault gouge material as observed in closed cracks. - Processing and analysing measured fluctuations of crack apertures and rock deformation in the time series as well as in the hydro-meteorological variables, in particular relative humidity Hr(t) and air temperature. - Studying and reconstructing the opening cycles on a drill-core sample under well-known laboratory conditions and observing potential propagation of

    Despite the high prevalence of pulmonary tuberculosis worldwide, extrapulmonary tuberculosis especially cutaneous and osteoarticular tuberculosis occurs rarely, both of which are often difficult to be recognized since their symptoms mimic those of many other cutaneous and osteoarticular diseases. Here, we present a rare case of cutaneous tuberculosis potentially accompanied by osteroarticular tuberculosis in a 36-year-old Chinese man who presented with multiple persistent skin ulcers for one year and were nonresponsive to multiple therapeutic approaches. A single anti-tuberculous regimen with rifampicin resulted in healing of all skin lesions and excellent recovery of the general condition. © 2018 Wiley Periodicals, Inc.

    A 37-year-old obese man who was a social drinker was admitted to our hospital to undergo a detailed examination for liver injury with anti-mitochondrial antibody positivity. Abdominal ultrasonography revealed moderate fatty liver. A histological analysis showed steatosis of approximately 30% of the hepatocytes, focal necrosis, a few ballooning hepatocytes and lobular inflammation suggestive of steatohepatitis, epithelioid granuloma and irregularity of the sequence of the bile duct epithelium accompanied by lymphocyte infiltration suggestive of chronic cholangitis. He was diagnosed with non-alcoholic steatohepatitis complicated with primary biliary cholangitis. His liver injury was improved by weight loss and high-dose ursodeoxycholic acid treatment.

    Full Text Available Introduction. Unruptured sinus of valsalva aneurysm (SVA is a rare congenital anomaly, particularly, when it coexists with a ventricular septal defect (VSD and aortic regurgitation due to the prolapse of the elongated aortic cusp into the VSD. In this report, we present the case of a 19-year-old young man with VSD challenging in spite of dyspnea and lower limb edema. Presentation of Case. Its diagnosis was made on the basis of transthoracic echocardiography results. Surgical management consisted of replacing the SVA with mechanical valve prosthesis. A Gore-Tex patch repaired the VSD. Discussion. In the follow-up periods, clinical and echocardiographic tests showed that the patient was in excellent status. Conclusion. SVA requires a surgical procedure due to its high risk of mortality in unoperated patients and a good safety of surgery.

    A 28-year-old man arrived for an outpatient cardiac MRI (CMR) study to evaluate cardiac structure. At the age of 24 the patient presented with acute onset expressive aphasia and was diagnosed with ischaemic stroke. Echocardiography at that time was reported as 'apical wall thickening consistent with apical hypertrophic cardiomyopathy'. CMR revealed a moderately dilated left ventricle with abnormal appearance of the left ventricular (LV) apical segments. Further evaluation was consistent with a diagnosis of LV non-compaction (LVNC) cardiomyopathy with a ratio of non-compacted to compacted myocardium measuring 3. There was extensive delayed hyperenhancement signal involving multiple segments representing a significant myocardial scar which is shown to have a prognostic role. Our patient, with no significant cerebrovascular risk factors, would likely have had an embolic stroke. This case demonstrates the role of CMR in accurately diagnosing LVNC in a patient with young stroke where prior echocardiography was non-diagnostic. 2014 BMJ Publishing Group Ltd.

    Safety and long-term behaviour of underground permanent repositories depend on a combination of several engineered and geological barriers. The properties of the geological barriers are the natural conditions of the formation, while the performance of the engineered barriers is a result of their design and construction. The properties of the engineered barriers are deeply influenced by the interactions between both geological and engineered barriers in response to the conditions expected in a high level waste repository. These interactions need to be identified and fully understood to allow their input in models describing the behaviour of the near field to predict reliably the long-term performance and safety of a repository. The Heating Experiment (HE) project, which is taking place at the Mont-Terri underground laboratory in Switzerland, is conceived as a research project to learn more about the coupled thermo-hydro-mechanical processes in a clay formation around a heat source similar to those in a potential repository, with special emphasis on the interaction between the clay host rock and the bentonite buffer that is part of the engineered barrier, under saturated conditions. This project is co-funded by the European Commission and performed as part of the fifth EURATOM framework programme, key action Nuclear Fission (1998-2002). For that purpose, a central vertical borehole of 300 mm diameter and 7 m deep was drilled and an electrical heater surrounded with a Spanish bentonite buffer was installed inside. More than seventeen boreholes were instrumented for measuring parameters such as temperatures, total pressures, radial displacements, gas/water release and for performing geo-electric tomography. A total of 112 instruments were installed. The complexity of the issues involved requires a multi-partner approach and there exists a mutual interest of national research organisations to co-operate on a European level: two national agencies, which are responsible

    A 24-year-old man, who was late attaining developmental milestones and tested in the severely mentally retarded range, had incurred third- and fourth-degree burns at 2.5 years that resulted in a deformed, anesthetic, and useless distal left upper limb. Following wrist disarticulation, he was fitted with a cosmetic prosthesis that he accepted enthusiastically. It permitted him to use his left upper limb as an effective assister. Attempts to wear and use a functional prosthesis were not successful because the bulbous stump was covered with abnormal skin that ulcerated whenever he wore the prosthesis. At present, he resides at home with his mother and has all self-care skills. He attends a day treatment program and helps his mother with household chores as well as neighborhood errands. The prognosis for continued functional improvement is good, even though he remains severely mentally retarded.

    Ventricular tachycardia (VT) is life-threatening subgroup of wide QRS complex tachycardia (WCT). VT is usually associated with structural heart diseases, but it can occur in the absence of any cardiovascular diseases. Adverse cardiac effect of sodium bicarbonate in healthy subjects is not well described. A 30-year-old healthy man with excessive intake of sodium bicarbonate-related VT is presented. He was using sodium bicarbonate during last 2 months to lose weight. He has no risk factors and any cardiovascular or systemic diseases. After intravenous administration of amiodarone, tachycardia ended and his rhythm converted to sinus rhythm with normal electrocardiogram. Patient is asymptomatic, and no VT was observed without any medications at 1 year of follow-up.

    2014-01-01

    Twenty-five same-sex-attracted rural young Thai men were interviewed three times to investigate how their sexual subjectivity changed over an 18-month period after they completed high school and moved into a new life-phase. Many young men grew up with strong gender-based understandings of homosexuality, in which a masculine (top) partner is seen as complementing a feminine (bottom) partner. The discursive division between the masculine and feminine domains became increasingly blurred in the actual practice of dating, forcing the young men to develop new understandings of homosexuality and same-sex relations. The shift from a rural to urban environment, the use of the Internet and the experience of falling in love played important roles in this experimentation with new, increasingly masculine presentations of the self, also influenced by a modern urban masculine aesthetic. The paper concludes that the encounter between 'traditional' gender-based homosexuality and new ideas, in which masculine object-choice is important in defining sexual identity leads to a variety of fluid ideas and expressions. This process created confusion among some, and opportunities for exploration of new ways of defining sexual subjectivities among others.

    The relationship between obesity and suicide risk is still unclear with controversial research results. The aim of this study is to investigate the relationship between obesity and suicide risk for men and women in a population-based study of young adults. This is a cross-sectional population-based study that identified young adults between 18 and 35 years of age. Suicide risk was investigated through the structured clinical interview Mini. Weight and height were assessed, and participants were classified as normal-weight body mass index (BMI obese (BMI > 30). The prevalence of obesity was of 19.9% of the total sample (n = 1953). Obesity was more prevalent among women and participants between 27 and 35 years of age. Suicide risk was present in 13.0% of the sample and more prevalent among women. In our study we found an association between obesity and suicide risk for women, but not for men. Obesity was associated with a higher prevalence of suicide risk in women. Given the strength of the relationship between BMI and suicide, identifying the mechanisms associated with obesity, especially for women, can lead to new insights into the prevention of suicide risk.

    Full Text Available Abstract A 27 year-old man who presented to the hospital with progressive lower extremity weakness, developed an acute ST elevation myocardial infarction on his second hospital day. Primary angioplasty to the left anterior descending coronary artery was performed. Due to persistent dyspnea, the patient underwent a diagnostic chest computed tomography which confirmed multiple small pulmonary emboli. Laboratory analysis revealed a megaloblastic anemia with a reduced vitamin B12 level and positive titers for antibodies against intrinsic factor, establishing a diagnosis of pernicious anemia. Screening for hypercoaguable markers documented an isolated severely elevated homocysteine levels (105 μmol/l. No other significant risk factors for coronary artery disease including a family history of premature atherosclerosis were identified. This case illustrates the importance of testing for hyperhomocysteinemia as part of a workup for atherothrombotic disease, especially in patients without other significant risk factors. The severity of hyperhomocysteinemia found in our patient is unusual for patients with vitamin B12 malabsorption and raises the question of whether the widely practiced folic acid fortification in the United States may mask or even worsen vitamin B12 deficiency over time, leading to more severe cases of vitamin B12 deficiency and hyperhomocysteinemia than seen in the past.

    There is growing evidence of an association between ADHD and rule-breaking behaviour and that subjects with ADHD are more likely to be involved in the legal system. However, the research on ADHD as a risk factor not only for delinquency but also for recidivism is scarce and findings are controversial. Therefore, we explored the impact of ADHD on the course of delinquency in a sample of incarcerated young men. We conducted a 15-year follow-up study by investigating the criminal records of 106 former youth prisoners. Criminal recidivism was operationalized through three variables: criminal recidivism; frequency of recidivism; and time to recidivism. The incremental predictive validity of ADHD was analysed using survival analysis and controlled for confounders associated with recidivism. Offenders with ADHD (n = 74) reoffended 2.5 times faster and showed a higher rate of recidivism and further incarcerations compared to non-ADHD offenders (n = 33), even when controlling for general risk factors such as antisocial personality disorder. Median survival rate ranged between 6 and 7 months in the ADHD groups and 25 months in the non-ADHD group. Our results revealed that ADHD has an incremental predictive power on criminal recidivism, even above general risk factors. Moreover, the criminogenic influence of ADHD appeared to be crucial in terms of the interplay of childhood ADHD, irrespectively of the persistence of the symptomatology into later life. Our findings therefore highlight the importance of early intervention and consequently prevention.

    Full Text Available Abstract Background Gastrointestinal stromal tumors (GIST are uncommon intra-abdominal tumors. These tumors tend to present with higher frequency in the stomach and small bowel. In fewer than 5% of cases, they originate primarily from the mesentery, omentum, or peritoneum. Furthermore, these extra-gastrointestinal tumors (EGIST tend to be more common in patients greater than 50 years of age. Rarely do EGIST tumors present in those younger than 40 years of age. Case presentation We report a case of a large EGIST in a 27-year-old male. An abdominal pelvic computerized tomography imaging demonstrated an intra-abdominal mass of 22 cm, without invasion of adjacent viscera or liver lesions. This mass was resected en bloc with its fused omentum and an adherent portion of sigmoid colon. Pathology results demonstrated a malignant gastrointestinal stromal tumor with positive CD117 (c-kit staining, and negative margins of resection, and no continuity of tumor with the sigmoid colon. Due to the malignant and aggressive nature of this patient's tumor, he was started on STI-571 as adjuvant chemotherapy. Conclusion Stromal tumors of an extra-gastrointestinal origin are rare. Of the reported omental and mesenteric EGISTs in four published series, a total of 99 tumors were studied. Of the 99 patients in these series only 8 were under 40 years of age, none were younger than 30 years old; and only 5 were younger than 35 years old. Our patient's age is at the lower end of the age spectrum for the reported EGISTs. Young patients who present with an extra-gastrointestinal stromal tumor (EGIST, who have complete resection with negative margins, have a good prognosis. There is little data to support the role of STI-571 in adjuvant or neoadjuvant therapy after curative resection. Given the lack of data, the use of STI-571 must be individualized.

    For constructing a nuclear waste repository and for ensuring the safety requirements are met over very long time periods, thorough knowledge about the safety-relevant processes occurring in the coupled system of waste containers, engineered barriers, and the host rock is indispensable. For respectively targeted research work, the Mont Terri rock laboratory is a unique facility where repository research is performed in a clay rock environment. It is run by 16 international partners, and a great variety of questions are investigated. Some of the work which GRS as one of the Mont Terri partners is involved in is presented in this article. The focus is on thermal, hydraulic and mechanical behaviour of host rock and/or engineered barriers.

    Microbiological studies related to the geological disposal of radioactive waste have been conducted at the Mont Terri rock laboratory in Opalinus Clay, a potential host rock for a deep geologic repository, since 2002. The metabolic potential of microorganisms and their response to excavation-induced effects have been investigated in undisturbed and disturbed claystone cores and in pore- (borehole) water. Results from nearly 15 years of research at the Mont Terri rock laboratory have shown that microorganisms can potentially affect the environment of a repository by influencing redox conditions, metal corrosion and gas production and consumption under favourable conditions. However, the activity of microorganisms in undisturbed Opalinus Clay is limited by the very low porosity, the low water activity, and the largely recalcitrant nature of organic matter in the claystone formation. The presence of microorganisms in numerous experiments at the Mont Terri rock laboratory has suggested that excavation activities and perturbation of the host rock combined with additional contamination during the installation of experiments in boreholes create favourable conditions for microbial activity by providing increased space, water and substrates. Thus effects resulting from microbial activity might be expected in the proximity of a geological repository i.e., in the excavation damaged zone, the engineered barriers, and first containments (the containers).

    This report presents the effort to extend the single-phase analytical Terry turbine model to cover two-phase off-design conditions. The work includes: (1) adding well-established two-phase choking models – the Isentropic Homogenous Equilibrium Model (IHEM) and Moody’s model, and (2) theoretical development and implementation of a two-phase nozzle expansion model. The two choking models provide bounding cases for the two-phase choking mass flow rate. The new two-phase Terry turbine model uses the choking models to calculate the mass flow rate, the critical pressure at the nozzle throat, and steam quality. In the divergent stage, we only consider the vapor phase with a similar model for the single-phase case by assuming that the liquid phase would slip along the wall with a much slower speed and will not contribute the impulse on the rotor. We also modify the stagnation conditions according to two-phase choking conditions at the throat and the cross-section areas for steam flow at the nozzle throat and at the nozzle exit. The new two-phase Terry turbine model was benchmarked with the same steam nozzle test as for the single-phase model. Better agreement with the experimental data is observed than from the single-phase model. We also repeated the Terry turbine nozzle benchmark work against the Sandia CFD simulation results with the two-phase model for the pure steam inlet nozzle case. The RCIC start-up tests were simulated and compared with the single-phase model. Similar results are obtained. Finally, we designed a new RCIC system test case to simulate the self-regulated Terry turbine behavior observed in Fukushima accidents. In this test, a period inlet condition for the steam quality varying from 1 to 0 is applied. For the high quality inlet period, the RCIC system behaves just like the normal operation condition with a high pump injection flow rate and a nominal steam release rate through the turbine, with the net addition of water to the primary system; for

    A 250 m-deep inclined well, the Mont Terri BDB-1, was drilled through the Jurassic Opalinus Clay and its bounding formations at the Mont Terri rock laboratory (NW Switzerland). For the first time, a continuous section from (oldest to youngest) the topmost members of the Staffelegg Formation to the basal layers of the Hauptrogenstein Formation is now available in the Mont Terri area. We extensively studied the drill core for lithostratigraphy and biostratigraphy, drawing upon three sections from the Mont Terri area. The macropaleontological, micropaleontological, and palynostratigraphical data are complementary, not only spatially but they also cover almost all biozones from the Late Toarcian to the Early Bajocian. We ran a suite of geophysical logs to determine formational and intraformational boundaries based on clay content in the BDB-1 well. In the framework of an interdisciplinary study, analysis of the above-mentioned formations permitted us to process and derive new and substantial data for the Mont Terri area in a straightforward way. Some parts of the lithologic inventory, stratigraphic architecture, thickness variations, and biostratigraphic classification of the studied formations deviate considerably from occurrences in northern Switzerland that crop out further to the east. For instance, with the exception of the Sissach Member, no further lithostratigraphic subdivision in members is proposed for the Passwang Formation. Also noteworthy is that the ca. 130 m-thick Opalinus Clay in the BDB-1 core is 20 m thinner than that equivalent section found in the Mont Terri tunnel. The lowermost 38 m of the Opalinus Clay can be attributed chronostratigraphically solely to the Aalensis Zone (Late Toarcian). Deposition of the Opalinus Clay began at the same time farther east in northern Switzerland (Aalensis Subzone, Aalensis Zone), but in the Mont Terri area the sedimentation rate was two or three orders of magnitude higher.

    “On postmodernism which refused to be deconstructed” Since 1991, the work of Terry Farrell has been connected with Asia. His saying “I am not afraid of looking backwards, as well as forwards” was again put to trial. There he had to join his contextual principles of architecture with the futuristic ambition of Asiatic investors: although the British Consulate in Hong Kong was called “very British”, its facade echoes both Hong Kong’s architecture and that of European Coliseum.

    The 20 papers in this Special Issue address questions related to the safe deep geological disposal of radioactive waste. Here we summarize the main results of these papers related to issues such as: formation of the excavation damaged zone, self-sealing processes, thermo-hydro-mechanical processes, anaerobic corrosion, hydrogen production and effects of microbial activity, and transport and retention processes of radionuclides. In addition, we clarify the question of transferability of results to other sites and programs and the role of rock laboratories for cooperation and training. Finally, we address the important role of the Mont Terri rock laboratory for the public acceptance of radioactive waste disposal. (author)

    Nuclear waste programs outside of the US have focused on different host rock types for geological disposal of high-level radioactive waste. Several countries, including France, Switzerland, Belgium, and Japan are exploring the possibility of waste disposal in shale and other clay-rich rock that fall within the general classification of argillaceous rock. This rock type is also of interest for the US program because the US has extensive sedimentary basins containing large deposits of argillaceous rock. LBNL, as part of the DOE-NE Used Fuel Disposition Campaign, is collaborating on some of the underground research laboratory (URL) activities at the Mont Terri URL near Saint-Ursanne, Switzerland. The Mont Terri project, which began in 1995, has developed a URL at a depth of about 300 m in a stiff clay formation called the Opalinus Clay. Our current collaboration efforts include two test modeling activities for the FE heater test and the HG-A leak-off test. This report documents results concerning our current modeling of these field tests. The overall objectives of these activities include an improved understanding of and advanced relevant modeling capabilities for EDZ evolution in clay repositories and the associated coupled processes, and to develop a technical basis for the maximum allowable temperature for a clay repository.

  3. The Origin of The Piz Terri-Lunschania zone (Central Alps, Switzerland)

    2017-04-01

    The Piz Terri-Lunschania zone (PTLZ) represents a band of metasedimentary rocks embedded in a crucial knot at the NE border of the Lepontine dome, at the intersection of the Gotthard, Lucomagno, Simano, Adula and Grava nappes. Its origin and its position in the tectonostratigraphy of the Central Alps are still not completely understood. A better understanding of this sedimentary zone and its tectonic position could shed lights on the Helvetic-Penninic connection and facilitate the disentanglement of the Lepontine dome tectonics. In this study we combine structural and stratigraphic observations with detrital zircon (DZ) and detrital rutile (DR) U-Pb geochronology as well as mineral trace element data from Permian, Triassic and Jurassic sandstones. We compare these data with those from adjacent tectonic units and coeval strata in other portions of the Alpine chain. Maximal depositional ages, abrupt changes in provenances and stratigraphic correlations based on new DZ and DR U-Pb and trace element data allow for a better understanding of the sedimentary evolution of the Terri basin and its palaeogeographic position along the northern margin of the Alpine Tethys. In particular the DZ U-Pb signatures, with its abundant 260-280 Ma zircons and the scarcity of 290-350 Ma zircons, corroborates an Ultra-Adula origin of the PTLZ as proposed by Galster et al (2010; 2012) based on stratigraphic arguments and reinforces the notion of a Briançonnais influence on the stratigraphic record of this complex zone, a fact that has important tectonic and Palaeogeographic implications.

    Geologic repositories for radioactive waste are designed as multi-barrier disposal systems that perform a number of functions including the long-term isolation and containment of waste from the human environment, and the attenuation of radionuclides released to the subsurface. The rock laboratory at Mont Terri (canton Jura, Switzerland) in the Opalinus Clay plays an important role in the development of such repositories. The experimental results gained in the last 20 years are used to study the possible evolution of a repository and investigate processes closely related to the safety functions of a repository hosted in a clay rock. At the same time, these experiments have increased our general knowledge of the complex behaviour of argillaceous formations in response to coupled hydrological, mechanical, thermal, chemical, and biological processes. After presenting the geological setting in and around the Mont Terri rock laboratory and an overview of the mineralogy and key properties of the Opalinus Clay, we give a brief overview of the key experiments that are described in more detail in the following research papers to this Special Issue of the Swiss Journal of Geosciences. These experiments aim to characterise the Opalinus Clay and estimate safety-relevant parameters, test procedures, and technologies for repository construction and waste emplacement. Other aspects covered are: bentonite buffer emplacement, high-pH concrete-clay interaction experiments, anaerobic steel corrosion with hydrogen formation, depletion of hydrogen by microbial activity, and finally, release of radionuclides into the bentonite buffer and the Opalinus Clay barrier. In the case of a spent fuel/high-level waste repository, the time considered in performance assessment for repository evolution is generally 1 million years, starting with a transient phase over the first 10,000 years and followed by an equilibrium phase. Experiments dealing with initial conditions, construction, and waste

    Clay-rich formations are considered to be a natural barrier for radionuclides or fluids (water, hydrocarbons, CO2) migration. However, little is known about the architecture of faults affecting clay formations because of their quick alteration at the Earth's surface. The Mont Terri Underground Research Laboratory provides exceptional conditions to investigate an un-weathered, perfectly exposed clay fault zone architecture and to conduct fault activation experiments that allow explore the conditions for stability of such clay faults. Here we show first results from a detailed geological model of the Mont Terri Main Fault architecture, using GoCad software, a detailed structural analysis of 6 fully cored and logged 30-to-50m long and 3-to-15m spaced boreholes crossing the fault zone. These high-definition geological data were acquired within the Fault Slip (FS) experiment project that consisted in fluid injections in different intervals within the fault using the SIMFIP probe to explore the conditions for the fault mechanical and seismic stability. The Mont Terri Main Fault "core" consists of a thrust zone about 0.8 to 3m wide that is bounded by two major fault planes. Between these planes, there is an assembly of distinct slickensided surfaces and various facies including scaly clays, fault gouge and fractured zones. Scaly clay including S-C bands and microfolds occurs in larger zones at top and bottom of the Mail Fault. A cm-thin layer of gouge, that is known to accommodate high strain parts, runs along the upper fault zone boundary. The non-scaly part mainly consists of undeformed rock block, bounded by slickensides. Such a complexity as well as the continuity of the two major surfaces are hard to correlate between the different boreholes even with the high density of geological data within the relatively small volume of the experiment. This may show that a poor strain localization occurred during faulting giving some perspectives about the potential for

    Friction experiment was conducted on samples from the Main Fault of Mont Terri Rock Laboratory, Switzerland and then micro-textures of deformed gouges were observed using a scanning electron microscope JCM-6000 and JXA-8530F. Samples were taken at the depths of 47.2m and 37.3m of borehole BSF-1, and at 36.7m, 37.1m, 41.4m and 44.6m of borehole BSF-2, which were drilled from the drift floor at 260m depth from the surface. Friction experiment was conducted on above 6 samples using a rotary shear low to high-velocity friction apparatus at the Institute of Geology, China Earthquake Administration in Beijing at a normal stress of 3.95 to 4.0 MPa and at slip rates ranging 0.2 microns/s to 2.1mm/s. Cylindrical specimens of Ti-Al-V alloy, exhibiting similar behaviors as the host rock specimen, were used as rotary and stationary pistons of 40 mm diameter. A Teflon sleeve was used around the piston to confine the sample during the test. Main results are summarized as follows. 1) Mud rocks in Mont Terri drill holes (BFS-1, BFS-2) had steady-state or nearly steady-state friction coefficient μss in the range of 0.1 0.3 for wet gouges and 0. 5 0.7 for dry gouges. Friction coefficients of dry gouges were approximately twice as large as those of wet gouges. However, the fault rock (37.3 m, BFS-1) with scaly fabric showed no difference between wet and dry conditions : μss (wet): 0.50 0.77, μss (dry): 0.45 0.78. This is probably because the clay contents of this rock is less ( 33 %) than those in other rocks (67 73 %) (Shimamoto, 2017). 2) Deformed gouges are characterized by well-developed slip zones adjacent to the rotary and stationary pistons, accompanied by slickenside surfaces with clear striations. Such slickenside surfaces are similar to those developed in the drill core samples used in our experiments. 3) Multiple slip zones were observed in the 37.3m of BFS-1 and the 36.7m of BFS-2 samples under dry condition, suggesting that a slip occurred in the interior of the gouge

    The international Mont Terri project started in January 1996. Research is carried out in the Mont Terri rock laboratory, an underground facility near the security gallery of the Mont Terri motorway tunnel (vicinity of St-Ursanne, Canton of Jura, Switzerland). The aim of the project is the geological, hydrogeological, geochemical and geotechnical characterisation of a clay formation, specifically of the Opalinus Clay. Twelve Partners from European countries and Japan participate in the project. These are ANDRA, BGR, CRIEPI, ENRESA, GRS, HSK, IRSN, JAEA, NAGRA, OBAYASHI, SCK.CEN and swisstopo. Since 2006, swisstopo acts as operator of the rock laboratory and is responsible for the implementation of the research programme decided by the partners. The three following reports are milestones in the research history of the Mont Terri project. It was the first time that an in-situ heating test with about 20 observation boreholes over a time span of several years was carried out in a clay formation. The engineered barrier emplacement experiment has been extended due to very encouraging measurement results and is still going on. The ventilation test was and is a challenge, especially in the very narrow microtunnel. All three projects were financially supported by the European Commission and the Swiss State Secretariat for Education and Research. The three important scientific and technical reports, which are presented in the following, have been provided by a number of scientists, engineers and technicians from the Partners, but also from national research organisations and private contractors. Many fruitful meetings where held, at the rock laboratory and at other facilities, not to forget the weeks and months of installation and testing work carried out by the technicians and engineers. The corresponding names and organisations are listed in detail in the reports. Special thanks are going to the co-ordinators of the three projects for their motivation of the team during

    As part of the efforts to understand the unexpected “self-regulating” mode of the RCIC (Reactor Core Isolation Cooling) systems in Fukushima accidents and extend BWR RCIC and PWR AFW (Auxiliary Feed Water) operational range and flexibility, mechanistic models for the Terry turbine, based on Sandia’s original work [1], have been developed and implemented in the RELAP-7 code to simulate the RCIC system. In 2016, our effort has been focused on normal working conditions of the RCIC system. More complex off-design conditions will be pursued in later years when more data are available. In the Sandia model, the turbine stator inlet velocity is provided according to a reduced-order model which was obtained from a large number of CFD (computational fluid dynamics) simulations. In this work, we propose an alternative method, using an under-expanded jet model to obtain the velocity and thermodynamic conditions for the turbine stator inlet. The models include both an adiabatic expansion process inside the nozzle and a free expansion process outside of the nozzle to ambient pressure. The combined models are able to predict the steam mass flow rate and supersonic velocity to the Terry turbine bucket entrance, which are the necessary input information for the Terry turbine rotor model. The analytical models for the nozzle were validated with experimental data and benchmarked with CFD simulations. The analytical models generally agree well with the experimental data and CFD simulations. The analytical models are suitable for implementation into a reactor system analysis code or severe accident code as part of mechanistic and dynamical models to understand the RCIC behaviors. The newly developed nozzle models and modified turbine rotor model according to the Sandia’s original work have been implemented into RELAP-7, along with the original Sandia Terry turbine model. A new pump model has also been developed and implemented to couple with the Terry turbine model. An input

    Document available in extended abstract form only. The Full-Scale Emplacement (FE) Experiment at the Mont Terri underground research laboratory (URL) is a full-scale heater test in a clay-rich formation. It simulates the construction, waste emplacement and backfilling of a spent fuel (SF) / vitrified high-level waste (HLW) repository tunnel as realistically as possible. The entire experiment implementation as well as the post-closure THM(C) evolution will be monitored using several hundred sensors. These are distributed in the host rock in the near- and far-field, the tunnel lining, the engineered barrier system and on the heaters. The aim of this experiment is to investigate HLW repository-induced thermo-hydro-mechanical (THM) coupled effects on the host rock and the validation of existing coupled THM models. A further aim is the verification of the technical feasibility of constructing a 50 m repository section at full scale with all relevant components using standard industrial equipment. Finally, the experiment will demonstrate the canister and buffer emplacement procedures for underground conditions based on the Swiss disposal concept. Experimental layout The FE experiment is based on the Swiss disposal concept for SF / HLW. The 50 m long test gallery, at the end of the former MB test tunnel in the Mont Terri URL, will be realised with a diameter of approx. 3 m. In the experiment gallery, 3 heaters with dimensions similar to those of waste canisters will be emplaced on top of abutments built of bentonite blocks. The remaining space will be backfilled with compacted bentonite pellets. The experiment will be sealed off towards the start niche with a concrete plug holding the buffer in place and reducing air and water fluxes. The first scoping calculations and design modelling for the 'far-field' instrumentation have been completed; these works have been carried out using CodeBRIGHT and the multiphase flow simulator TOUGH2. With an initial heat output of 1500 W

    The paper presents an overview of the behaviour of Opalinus Clay under thermal loading as observed in three in situ heating tests performed in the Mont Terri rock laboratory: HE-B, HE-D and HE-E. The three tests are summarily described; they encompass a broad range of test layouts and experimental conditions. Afterwards, the following topics are examined: determination of thermal conductivity, thermally-induced pore pressure generation and thermally-induced mechanical effects. The mechanisms underlying pore pressure generation and dissipation are discussed in detail and the relationship between rock damage and thermal loading is examined using an additional in situ test: SE-H. The paper concludes with an evaluation of the various thermo-hydro-mechanical (THM) interactions identified in the heating tests. (authors)

    We appreciate Terry and Goff's thoughtful comment in response to our proposed atoll development model. Flank collapse of reef-built slopes likely does affect plan-form atoll morphology in some locations and potentially poses a tsunami hazard to low-lying Pacific islands (Terry and Goff, 2013). However, given the often rapid rates of lagoon infill (> 1 mm/yr; Montaggioni, 2005), such failure events would likely need to be frequent and widespread in order to leave a morphologic imprint on modern western Pacific atoll lagoon depths. Few atoll flank collapse features have been dated but many of the arcuate bight-like structures (ABLS) identified could be inherited from scars incised into the initial volcanic edifice (e.g. Terry and Goff, 2013 and refs. therein) — submarine mass wasting has been extensively documented on young hotspot islands (e.g. Hawaiian Islands: Moore et al., 1989; Reunion: Oehler et al., 2008). Atolls in the Marshall Islands, where our main study site Enewetak Atoll is located, are likely ~ 50–100 million years old (Larson et al., 1995) and dating of adjacent deep-water turbidite aprons in the Nauru Basin (DSDP Site 462; Schlanger and Silva, 1986) suggests that large atoll flank collapse events have been relatively infrequent there since the mid-Miocene (wasting events, will be essential for exploring the plan-form and 3D shapes of atolls. To our knowledge, no quantitative model of long-term atoll development has explicitly linked lagoon restriction/sedimentation to episodic flank collapse events (e.g. Montaggioni et al., 2015; Paterson et al., 2006; Quinn, 1991; Warrlich et al., 2002). Testing Terry and Goff's proposed conceptual model for how rim failure processes affect atoll morphology in a numerical context will require deep drilling along arcuate bight-like structures, as well as adjacent, unaffected, rim and lagoon areas, in order quantify how often failures occur and how quickly the rim/lagoon is rebuilt afterwards.

    Increase in extramarital sex among youths, gender-based violence, lack of contraceptive knowledge among newly married couples and lack of knowledge of protection against diseases like STIs/HIV are the information and service needs of young people that need to be addressed urgently in order to make them future knowledgeable, responsible, and non-violent partners. In addressing these needs the gatekeepers, including parents, formal and informal community leaders and teachers, play a critical role, by facilitating/hindering access to appropriate and correct information about sexual and reproductive health to young people. The study was conducted in a district of Uttaranchal, India. The specific objective was to understand the social context and gatekeepers' views on family planning and sexual and reproductive health needs of young men. Thirty-two in-depth interviews and four focus group discussions were conducted with parents, formal and informal community leaders, teachers, and selected development officials. The findings indicate that gatekeepers are worried about rapid changes in the aspiration, expectation, and behavior of young men. Most of them were seriously concerned about the increasing drinking habit, use of drugs, and changing values of sexuality leading to various risk behaviors among young men. They felt that many of these changes are consequences of wider societal changes, rising aspirations, explosion of electronic media, and globalization of a new youth culture where extramarital sex, alcohol consumption, and violence are expressions of different facets of masculinity and symbols of the affluent class. Overall, there was a feeling that TV/films and their peers now influence more the socialization of young people and parents are losing control in guidance and mentoring of their children.

    Fusobacterium nucleatum is a strict anaerobic microorganism that causes disease entities such as periodontal and soft tissue abscesses, pulmonary and intraabdominal infections and very rarely intracerebral infections. Here, we report the rare case of a previously healthy 25-year-old German man with a cerebellar abscess caused by Fusobacterium nucleatum that resulted in rapid brain death. Toxicological screening showed positivity for amphetamines and cannabis. The diagnosis was obtained by polymerase chain reaction amplification of bacterial deoxyribonucleic acid in cerebrospinal fluid. In drug users clinicians should think about rare causes of brain abscesses/meningitis. Early diagnosis is necessary and justifies the use of molecular techniques.

    Between December 2001 and May 2004, a ventilation experiment (VE) was performed in the Mont Terri Underground Research Laboratory (URL) and co-financed by the Commission of the European Communities. The objective was to investigate the desaturation of consolidated clay formations in consequence of the ventilation of underground openings of a repository in such a formation. The results of the geoelectric measurements performed in the second phase of the Mont Terri ventilation test can be summarized as follows: Geoelectric tomography has been found suitable for monitoring ventilation-induced saturation changes in the Opalinus clay. During ventilation with dry air a desaturation down to below 50% could be detected in both desaturation cycles. The desaturated zone extends less than 0.5 m into the rock around the microtunnel. During the second resaturation phase, ventilation with humid air led to quick resaturation at the tunnel surface, while resaturation of the rock mass took months. The still ongoing third resaturation phase seems to imply that resaturation of the rock mass may take years with no air circulation in the tunnel. The laboratory investigations on the Opalinus clay included the determination of water retention capacity, swelling pressure, free swelling/shrinking strains induced by moisture changes, and response of normal and large hollow clay samples to the ventilation of the central boreholes at different air humidity values. The Opalinus clay has a high water absorption capacity. The amount of water uptake in unconstraint conditions is much higher than the water content in the naturally confined state, indicating that the pore water in the natural clay rock is predominantly bound on clay minerals. The swelling pressure induced by wetting with vapour is very close to the major lithostatic stress at the sampling location. Water uptake from vapour causes a large free expansion of up to 12% over 8 months and even a breakdown along bedding planes. Release of

    Full Text Available The very public death of Terri Schiavo in 2005 alerted Americans to what is a growing ethical, medical, and social crisis: the status of end-of-life issues and decisions in the United States. Currently, Oregon is the only state to give terminally ill patients the right to end their lives, with physicians’ help, if they so choose. Public opinion data from 1977 to the present show that Americans support greater rights for individuals facing end-of-life decisions--up to and including physician-assisted suicide and euthanasia. This paper considers the status of end-of-life issues in the United States after Terri Schiavo’s death and examines the opportunities for advocacy by social workers who serve clients and families encountering this complex and controversial issue.

    Two experiments have been installed at Mont Terri in 2004 and 2009 that allowed gas circulation within a borehole at a pressure between 1 and 2 bar. These experiments made it possible to observe the natural gases that were initially dissolved in pore-water degassing into the borehole and to monitor their content evolution in the borehole over several years. They also allowed for inert (He, Ne) and reactive (H{sub 2}) gases to be injected into the borehole with the aim either to determine their diffusion properties into the rock pore-water or to evaluate their removal reaction kinetics. The natural gases identified were CO{sub 2}, light alkanes, He, and more importantly N{sub 2}. The natural concentration of four gases in Opalinus Clay pore-water was evaluated at the experiment location: N{sub 2} 2.2 mmol/L ± 25%, CH{sub 4} 0.30 mmol/L ± 25%, C{sub 2}H{sub 6} 0.023 mmol/L ± 25%, C{sub 3}H{sub 8} 0.012 mmol/L ± 25%. Retention properties of methane, ethane, and propane were estimated. Ne injection tests helped to characterize rock diffusion properties regarding the dissolved inert gases. These experimental results are highly relevant towards evaluating how the fluid composition could possibly evolve in the drifts of a radioactive waste disposal facility. (authors)

    To study associations between crime and psychiatric disorders among adolescent males in a representative population-based cohort study. The sample includes 2,712 Finnish boys born in 1981. Information on criminality consists of offenses registered in the Finnish National Police Register 1998-2001. Crime was classified according to frequency and type (drug, violent, property, traffic, and drunk driving offenses). Information on psychiatric diagnoses between 1999 and 2004 was collected from the Finnish National Military Register. Of the 2,712 boys, 22% had a crime registration during the 4-year period, and 10% had at least one psychiatric disorder according to the Military Register. Those with psychiatric disorders accounted for 49% of all crimes. Of those with more than five crimes (n = 98), 59% had psychiatric diagnoses. After adjusting for other crime types and childhood socio-economic status, property crime was independently associated with several diagnoses: antisocial personality (APD), substance use (SUD), psychotic, anxiety, and adjustment disorders. Drug offending was independently associated with APD, SUD, and psychotic disorder, and traffic offenses with APD. Youth crime is predominantly associated with antisocial personality and substance use disorders. Crime prevention efforts should focus on boys showing a risk for antisocial and substance use problems. In particular, property, drug, and repeat offenders need mental health and substance use assessment. There is a need to develop integrated mental health and substance use treatment services for young offenders within or alongside the criminal justice system.

    Document available in extended abstract form only. Argillaceous formations of low permeability are considered in several countries as potential host rocks for the disposal of high level radioactive wastes (HLRW). In order to determine their suitability for waste disposal, evaluations of the hydro-geochemistry and transport mechanisms from such geologic formations to the biosphere must be undertaken. The migration of radionuclides through the geosphere will occur predominantly in the aqueous phase, and hence the pore water chemistry plays an important role in determining ion diffusion characteristics in argillaceous formations. Consequently, a great effort has been made to characterise the pore water chemistry in clay-rocks formations. In the last 10 years various techniques were developed for determining pore water composition of clay-rocks including both direct and indirect methods: 1) In situ pore water sampling (water and gas) from sealed boreholes (Pearson et al., 2003; Vinsot et al. 2008); 2) Laboratory pore water sampling from unaltered core samples by the squeezing technique at high pressures (Fernandez et al., 2009); and 3) Characterization of the water chemistry by geochemical modelling (Gaucher et al. 2009). Pore water chemistry in clay-rocks and extraction techniques were documented and reviewed in different studies (Sacchi et al., 2001). Recovering pristine pore water from low permeable and low water content systems is very difficult and sometimes impossible. Besides, uncertainties are associated to each method used for the pore water characterization. In this paper, a review about the high pressure squeezing technique applied to indurate clay-rocks was performed. For this purpose, the experimental work on Opalinus Clay at the Mont Terri Research Laboratory during the last ten years was evaluated. A complete discussion was made about different issues such as: a) why is necessary to obtain the pore water by squeezing in the context of radioactive waste

    The Cement-Opalinus Clay Interaction (CI) Experiment at the Mont Terri rock laboratory is a long-term passive diffusion-reaction experiment between contrasting materials of relevance to engineered barrier systems/near-field for deep disposal of radioactive waste in claystone (Opalinus Clay). Reaction zones at interfaces of Opalinus Clay with two different types of concrete (OPC and 'low-pH'/ESDRED) were examined by sampling after 2.2 and 4.9 years. Analytical methods included element mapping (SEM, EPMA), select spot analysis (EDAX), 14C-MMA impregnation for radiography, and powder methods (IR, XRD, clay-exchanger characterisation) on carefully extracted miniature samples (mm). The presence of aggregate grains in concrete made the application of all methods difficult. Common features are a very limited extent of reaction within claystone, and a distinct and regularly zoned reaction zone within the cement matrix that is more extensive in the low-alkali cement (ESDRED). Both interfaces feature a de-calcification zone and overprinted a carbonate alteration zone thought to be mainly responsible for the observed porosity reduction. While OPC shows a distinct sulphate enrichment zone (indicative of ingress from Opalinus Clay), ESDRED displays a wide Mg-enriched zone, also with claystone pore-water as a source. A conclusion is that substitution of OPC by low-alkali cementitious products is not advantageous or necessary solely for the purpose of minimizing the extent of reaction between claystone and cementitious materials. Implications for reactive transport modelling are discussed. (authors)

    Opalinus Clay is currently being assessed as the host rock for a deep geological repository for high-level and low- and intermediate-level radioactive wastes in Switzerland. Within this framework, the 'Full-Scale Emplacement' (FE) experiment was initiated at the Mont Terri rock laboratory close to the small town of St-Ursanne in Switzerland. The FE experiment simulates, as realistically as possible, the construction, waste emplacement, backfilling and early post-closure evolution of a spent fuel/vitrified high-level waste disposal tunnel according to the Swiss repository concept. The main aim of this multiple heater test is the investigation of repository-induced thermo-hydro-mechanical (THM) coupled effects on the host rock at this scale and the validation of existing coupled THM models. For this, several hundred sensors were installed in the rock, the tunnel lining, the bentonite buffer, the heaters and the plug. This paper is structured according to the implementation timeline of the FE experiment. It documents relevant details about the instrumentation, the tunnel construction, the production of the bentonite blocks and the highly compacted 'granulated bentonite mixture' (GBM), the development and construction of the prototype 'backfilling machine' (BFM) and its testing for horizontal GBM emplacement. Finally, the plug construction and the start of all 3 heaters (with a thermal output of 1350 Watt each) in February 2015 are briefly described. In this paper, measurement results representative of the different experimental steps are also presented. Tunnel construction aspects are discussed on the basis of tunnel wall displacements, permeability testing and relative humidity measurements around the tunnel. GBM densities achieved with the BFM in the different off-site mock-up tests and, finally, in the FE tunnel are presented. Finally, in situ thermal conductivity and temperature measurements recorded during the first heating months

    Knowledge of the pore water chemistry in clay rock formations plays an important role in determining radionuclide migration in the context of nuclear waste disposal. Among the different in situ and ex-situ techniques for pore water sampling in clay sediments and soils, squeezing technique dates back 115 years. Although different studies have been performed about the reliability and representativeness of squeezed pore waters, more of them were achieved on high porosity, high water content and unconsolidated clay sediments. A very few of them tackled the analysis of squeezed pore water from low-porosity, low water content and highly consolidated clay rocks. In this work, a specially designed and fabricated one-dimensional compression cell two directional fluid flow was used to extract and analyse the pore water composition of Opalinus Clay core samples from Mont Terri (Switzerland). The reproducibility of the technique is good and no ionic ultrafiltration, chemical fractionation or anion exclusion was found in the range of pressures analysed: 70-200 MPa. Pore waters extracted in this range of pressures do not decrease in concentration, which would indicate a dilution of water by mixing of the free pore water and the outer layers of double layer water (Donnan water). A threshold (safety) squeezing pressure of 175 MPa was established for avoiding membrane effects (ion filtering, anion exclusion, etc.) from clay particles induced by increasing pressures. Besides, the pore waters extracted at these pressures are representative of the Opalinus Clay formation from a direct comparison against in situ collected borehole waters. (Author)

    The paper represents a summary about our research projects conducted between 2003 and 2015 related to the mechanical behaviour of Opalinus Clay at Mont Terri. The research summarized covers a series of laboratory and field tests that address the brittle failure behaviour of Opalinus Clay, its undrained and effective strength, the dependency of petro-physical and mechanical properties on total suction, hydro-mechanically coupled phenomena and the development of a damage zone around excavations. On the laboratory scale, even simple laboratory tests are difficult to interpret and uncertainties remain regarding the representativeness of the results. We show that suction may develop rapidly after core extraction and substantially modifies the strength, stiffness, and petro-physical properties of Opalinus Clay. Consolidated undrained tests performed on fully saturated specimens revealed a relatively small true cohesion and confirmed the strong hydro-mechanically coupled behaviour of this material. Strong hydro-mechanically coupled processes may explain the stability of cores and tunnel excavations in the short term. Pore-pressure effects may cause effective stress states that favour stability in the short term but may cause longer-term deformations and damage as the pore-pressure dissipates. In-situ observations show that macroscopic fracturing is strongly influenced by bedding planes and faults planes. In tunnel sections where opening or shearing along bedding planes or faults planes is kinematically free, the induced fracture type is strongly dependent on the fault plane frequency and orientation. A transition from extensional macroscopic failure to shearing can be observed with increasing fault plane frequency. In zones around the excavation where bedding plane shearing/shearing along tectonic fault planes is kinematically restrained, primary extensional type fractures develop. In addition, heterogeneities such as single tectonic fault planes or fault zones

    Transport and retardation parameters of radionuclides, which are needed to perform a safety analysis for a deep geological repository for radioactive waste in a compacted claystone such as Opalinus Clay, must be based on a detailed understanding of the mobility of nuclides at different spatial scales (laboratory, field, geological unit). Thanks to steadily improving experimental designs, similar tracer compositions in different experiments and complementary small laboratory-scale diffusion tests, a unique and large database could be compiled. This paper presents the main findings of 20 years of diffusion and retention experiments at the Mont Terri rock laboratory and their impact on safety analysis. (authors)

    Document available in extended abstract form only. The study of the interactions of steel pieces with an argillaceous rock is the aim of the IC experiment carried out in the Mont Terri Rock Laboratory (Switzerland). More precisely, the IC experiment consists in monitoring the corrosion rate of various steel (Inconel 690, 316L stainless steel, 2 carbon steels one representative of Andra concept and another of Nagra concept) at 80 deg. C, in anaerobic condition, in contact with the Opalinus clay formation. The corrosion rate monitoring is based on Electrochemical Impedance Spectroscopy (EIS). This method is not disturbing for the corrosion process i.e. the corrosion rate doesn't change during the electrochemical measurement. The main drawback of this method is that the corrosion process must be in stationary or quasi stationary state: EIS can only measure corrosion rates which do not change quickly with time. This method is well adapted for long term corrosion monitoring because long term corrosion rate evolves slowly. A special design of the experimental setup was developed to allow optimal interactions between rock and steel samples. It consists in mounting the steel samples inside of a bore-core section. This section is then placed at the extremity of the borehole equipment. The equipment is inserted in a vertical descending borehole and sealed by a large packer. Another particularity of the experimental setup is the possibility of heating the experimental section up to 80 deg. C. Finally, the equipment was built in such a way that such that it will be retrievable from the borehole after several years of experiment, in order to perform further analyses on the reacting materials (core and steel samples). A circulation loop links the experimental interval to the sampling, measuring various parameters (pH, Eh, electrical conductivity, dissolved oxygen and hydrogen) and control equipment installed in a cabinet, in the gallery of the underground laboratory.

    Document available in extended abstract form only. Because of their favourable hydraulic and retention properties that limit the migration of radionuclides, indurated clays are being considered as potential host rocks for radioactive waste disposal. Migration of radionuclides by diffusion and retention is thereby one of the main concerns for safety assessment and therefore carefully investigated at different scales. The transfer from dispersed sorption batch and diffusion data from lab experiments to field scale is however not always straightforward. Thus, combined sorption and diffusion experiments at both lab and field scale are instrumental for a critical verification of the applicability of such sorption and diffusion data. The present migration field experiment 'DR' (Diffusion and Retention experiment) at the Mont Terri Rock Laboratory (Switzerland) is the continuation of a series of successful diffusion experiments. The design is based on these previous diffusion experiments and has been extended to two diffusion chambers in a single borehole drilled perpendicular to the bedding plane. The radionuclides were injected as a pulse in both upper and lower loops where artificial pore water is circulating. The injected tracers were tritium, iodide, bromide, sodium-22, strontium-85, caesium (stable) for the lower diffusion chamber and deuterium caesium-137, barium-133, cobalt-60, europium-152, selenium (stable) and selenium-75 for the lower diffusion chamber. Their decrease in the circulation fluid - as they diffuse into the clay - is continuously monitored by online?-detection and regular sampling. The goals are fourfold (i) obtain diffusion and retention data for moderately to strongly sorbing tracers and to verify the corresponding data obtained on small-scale lab samples, (ii) improve diffusion data for the rock anisotropy, (iii) quantify effects of the borehole-disturbed zone for non-reactive tracers and (iv) improve data for long term diffusion.

The THM evolution in the host rock (near- and far-field), tunnel lining and the engineered barrier system will be monitored by several hundred conventional sensors. In addition to thermo-resistive conventional temperature sensors fiber-optic cables amend the temperature monitoring. In the host rock 45 m long inclinometer casings are equipped with fiber-optic cables to observe the longitudinal temperature evolution above the tunnel. The temperature distribution at the interface engineered barrier - tunnel lining is planned to be monitored by fiber-optic cables covering the surface of the tunnel lining. The fiber-optics in combination with the conventional temperature sensors will result in detailed insights into non-uniformity of heat transport within the engineered barrier and the host rock caused by spatial and temporal variability of thermal conductivity and therewith saturation and porosity.

    This article summarizes recent findings in a case study of exceptional longevity. CM, a resident of San Rafael, California, was 114 years old in August 1996. He is the first properly verified case of a 114-year-old man in human history (although a few women have been known to live longer). Our...... is accurate. Based on the available information, it also seems a reasonable conjecture that he may be the oldest man alive today and perhaps the oldest man who has ever lived. This study documents an extreme example of human longevity and records characteristics of the man's life that may provide clues about...

  17. On the contemporary – and contemporary art history. A review of Terry Smith, What Is Contemporary Art

    Directory of Open Access Journals (Sweden)

    Anthony Gardner

    2011-06-01

    Full Text Available This analysis of Terry Smith’s 'What Is Contemporary Art?' evaluates Smith’s ongoing project to theorise contemporary art around the theme of multiple, interconnected temporalities. It questions how this ‘contemporaneity’ differs from the classic teleologism of modernism and postmodern relativism and suggests that Smith’s categories may be valuable for understanding other cultural areas, such as contemporary music. It then raises methodological problems associated with charting the terrain of contemporary art and how they overlap with economic considerations, arguing that the task implies particular forms of privilege that may threaten the autonomy of critical analysis, but that Smith’s work goes some way toward exposing this problem.

  18. Microbial investigations in Opalinus clay from Mont Terri and in Callovo-Oxfordian argillite from Meuse/Haute-Marne

    The subject of this Ph.D. thesis deals with research achieved in the context of the Axis 2 of the law Bataille voted on December 30, 1991 about the possibility of building a deep geological repository for medium or high activity and long living nuclear waste. Nearby such a site, some microorganisms may influence the mobility of radionuclides coming from the waste canisters. This work consisted in looking for autochthonous microorganisms in the Opalinus clay formation from Mont Terri (Switzerland) and in the Callovo-Oxfordian argillite from Meuse/Haute-Marne (France). Microbial Investigations in these unknown unperturbed environments suggested very low microbial densities in the clayey sediments. However, new bacterial species could be isolated from those samples. In addition, a part of the allochthonous population, which has been introduced by air and human activity, could be identified in the Meuse/Haute-Marne underground research laboratory. (author)

    2008-01-01

    The EC Integrated Project, IP ESDRED (Engineering Studies and Demonstration of Repository Designs) was commissioned to establish a sound technical basis for demonstrating the safety of disposing of spent fuel and long-lived radioactive wastes in deep geological formations and to underpin the development of a common European view on the main issues related to the management and disposal of radioactive waste. The in situ development of non-intrusive monitoring techniques is included within the programme as an important component of the overall ESDRED programme. Monitoring will play an important role in providing information to the repository operator and to society in general and to support decision-making about if and when, to move from one phase to the next. The challenges, when constructing engineered barrier systems (EBS) to isolate the waste, is the ability to monitor the waste and the barriers, once isolated. Conventional monitoring systems depend upon wires or cable s to transfer information from the monitoring sensors outside the barriers. Monitoring sensors also have a limited lifetime and new sensors cannot be emplaced without disturbing the barrier. The development of non-intrusive monitoring systems which do not rely upon 'hard-wired' connection, thus providing the opportunity for continued monitoring after isolation. The ESDRED partners developed a programme utilising cross-hole seismic tomography to monitor an experimental demonstration by Nagra at Mont Terri Underground Research Laboratory (URL). The work programme includes PhD studies to conduct full seismic waveform analysis and to develop algorithms to address natural anisotropy in the Opalinus clay at Mont Terri. Following on from the ESDRED developments, some of ESDRED partner organisations identified a further opportunity for developing in situ monitoring techniques utilising the construction and testing programme of a low pH shotcrete plug being constructed in granite at the Grimsel Test Site

    For the safe disposal of high-level radioactive waste, different host rocks are currently considered. The favorable properties of claystone are low permeability, retention capacity for some radionuclides, and the ability to self-seal cracks, e.g. by swelling or time-dependent compaction creep. For the understanding of the long-term behavior of clay host rocks, the interaction between mechanical behavior, micro fabric, and mineral composition has to be understood (Bock et al., 2010). In the international research project Mont Terri (Switzerland) the Opalinus Clay (Jurassic Formation) is investigated in an underground rock laboratory (URL). In the present study the relationship between mechanical, mineralogical and micro fabric properties were studied on representative samples of the sandy and shaly facies of the Opalinus Clay (OPA) from Mont Terri. The mineral composition of all samples was analysed by using a complex mineral phase analysis. Therefore, the results of the X-ray diffraction, X-ray fluoreszence, organic and inorganic carbonate analysis (LECO) were adjusted with each other. In the case of the sandy facies (OPA) the mechanical strength inrcreases with increasing carbonate content. Here small carbonate particles form the matrix and act as stabilisator. The carbonates of the shaly facies (OPA), on the other hand, are mainly fossil fragments (e.g. shells) aligned parallel to bedding. These large carbonate particles are acting as predetermined breaking surfaces. Hence, in the case of shaly facies (OPA) the mechanical strength decreases with increasing carbonate content. Image Analyses (Fiji registered ) of scattering electron microscope images of polished sections proved the determined microstructural differences. Besides, carbonate particles in the sandy facies are mostly isometric, in contrast carbonates of the shaly facies show different shapes. This is explained further in terms of the aspect ratio. The mechanical tests were carried out as triaxial

    To make real and accurate dose assessment method so far, it is necessitated to provide ''Reference Japanese Man'' based on anotomical, physiological and biochemical data of Japanese people instead of the Reference Man presented in ICRP Publications 23 and 30. This review describes present status of researched for the purpose of establishing of Reference Japanese Man. The Reference Japanese Man is defined as a male or female adult who lives in Japan with a Japanese life-style and food custom. His stature and body weight, and the other data was decided as mean values of male or female people of Japan. As for food custom, Japanese people take significantly smaller amount of meat and milk products than Western people, while larger intake amount of cereals and marine products such as fish or seaweeds. Weight of organs is a principal factor for internal dose assessment and mean values for living Japanese adult has been investigated and the value employable for dose assessment for organs and tissues are shown. To employ these values of Reference Japanese Man, it should be taken into account of age. Metabolic parameters should also be considered. Iodine metabolism in Japanese is quite different from that of Western people. The above-mentioned data are now tentatively employing in modification of table of MIRD method and others. (Takagi, S.)

  8. Symbolism in prehistoric man.

    The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

    The VE (ventilation) test carried out at the Mont Terri underground laboratory in Switzerland intended to evaluate in situ the behaviour of a consolidated clay formation when subjected to alternate periods of flow of wet and dry air during several months. For that, a 10-m gallery was excavated in the Opalinus Clay formation and carefully instrumented. Before and after a second ventilation phase boreholes were drilled. Samples were taken from the drill cores and were analysed from mineralogical and geochemical points of view. Also, the retention curves of these samples were determined in the laboratory following drying paths performed under free volume conditions at 20 degree centigrade, what is the content of this report. Although there are not large differences in the WRC of samples taken from different boreholes, at different distances from the gallery wall or before or after ventilation, those samples taken near the gallery wall and after ventilation tend to show a higher water retention capacity. This has been correlated to the higher salinity of the pore water of these samples, what increases their osmotic suction. This effect is attenuated towards high suctions. (Author) 10 refs.

    The present study reports on elemental and Sr isotopic analyses of calcite and associated celestite infillings of various microtectonic features collected mostly in the Main Fault of the Opalinus Clay from Mont Terri rock laboratory. Based on a detailed microstructural description of veins, slickensides, scaly clay aggregates and gouges, the geochemical signatures of the infillings were compared to those of the leachates from undeformed Opalinus Clay, and to the calcite from veins crosscutting Hauptrogenstein, Passwang and Staffelegg Formations above and below the Opalinus Clay. Vein calcite and celestite from Main Fault yield identical {sup 87}Sr/{sup 86}Sr ratios that are also close to those recorded in the Opalinus Clay matrix inside the Main Fault, but different from those of the diffuse Opalinus Clay calcite outside the fault. These varied {sup 87}Sr/{sup 86}Sr ratios of the diffuse calcite evidence a lack of interaction among the associated connate waters and the flowing fluids characterized by a homogeneous Sr signature. The {sup 87}Sr/{sup 86}Sr homogeneity at 0.70774 ± 0.00001 (2σ) for the infillings of most microstructures in the Main Fault, as well as of veins from nearby limestone layer and sediments around the Opalinus Clay, claims for an 'infinite' homogeneous marine supply, whereas the gouge infillings apparently interacted with a fluid chemically more complex. According to the known regional paleogeographic evolution, two seawater supplies were inferred and documented in the Delémont Basin: either during the Priabonian (38-34 Ma ago) from western Bresse graben, and/or during the Rupelian (34-28 Ma ago) from northern Rhine Graben. The Rupelian seawater that yields a mean {sup 87}Sr/{sup 86}Sr signature significantly higher than those of the microstructural infillings seems not to be the appropriate source. Alternatively, Priabonian seawater yields a mean {sup 87}Sr/{sup 86}Sr ratio precisely matching that of the leachates from diffuse

  17. Experiments on thermo-hydro-mechanical behaviour of Opalinus Clay at Mont Terri rock laboratory, Switzerland

    Full Text Available Repositories for deep geological disposal of radioactive waste rely on multi-barrier systems to isolate waste from the biosphere. A multi-barrier system typically comprises the natural geological barrier provided by the repository host rock – in our case the Opalinus Clay – and an engineered barrier system (EBS. The Swiss repository concept for spent fuel and vitrified high-level waste (HLW consists of waste canisters, which are emplaced horizontally in the middle of an emplacement gallery and are separated from the gallery wall by granular backfill material (GBM. We describe here a selection of five in-situ experiments where characteristic hydro-mechanical (HM and thermo-hydro-mechanical (THM processes have been observed. The first example is a coupled HM and mine-by test where the evolution of the excavation damaged zone (EDZ was monitored around a gallery in the Opalinus Clay (ED-B experiment. Measurements of pore-water pressures and convergences due to stress redistribution during excavation highlighted the HM behaviour. The same measurements were subsequently carried out in a heater test (HE-D where we were able to characterise the Opalinus Clay in terms of its THM behaviour. These yielded detailed data to better understand the THM behaviours of the granular backfill and the natural host rock. For a presentation of the Swiss concept for HLW storage, we designed three demonstration experiments that were subsequently implemented in the Mont Terri rock laboratory: (1 the engineered barrier (EB experiment, (2 the in-situ heater test on key-THM processes and parameters (HE-E experiment, and (3 the full-scale emplacement (FE experiment. The first demonstration experiment has been dismantled, but the last two ones are on-going.

    Carbon steel is widely considered as a candidate material for the construction of spent fuel and high-level waste disposal canisters. In order to investigate corrosion processes representative of the long term evolution of deep geological repositories, two in situ experiments are being conducted in the Mont Terri rock laboratory. The iron corrosion (IC) experiment, aims to measure the evolution of the instantaneous corrosion rate of carbon steel in contact with Opalinus Clay as a function of time, by using electrochemical impedance spectroscopy measurements. The Iron Corrosion in Bentonite (IC-A) experiment intends to determine the evolution of the average corrosion rate of carbon steel in contact with bentonite of different densities, by using gravimetric and surface analysis measurements, post exposure. Both experiments investigate the effect of microbial activity on corrosion. In the IC experiment, carbon steel showed a gradual decrease of the corrosion rate over a period of 7 years, which is consistent with the ongoing formation of protective corrosion products. Corrosion product layers composed of magnetite, mackinawite, hydroxychloride and siderite with some traces of oxidising species such as goethite were identified on the steel surface. Microbial investigations revealed thermophilic bacteria (sulphate and thiosulphate reducing bacteria) at the metal surface in low concentrations. In the IC-A experiment, carbon steel samples in direct contact with bentonite exhibited corrosion rates in the range of 2 µm/year after 20 months of exposure, in agreement with measurements in absence of microbes. Microstructural and chemical characterisation of the samples identified a complex corrosion product consisting mainly of magnetite. Microbial investigations confirmed the limited viability of microbes in highly compacted bentonite. (authors)

    Repository concepts in clay or crystalline rock involve bentonite-based buffer or seal systems to provide containment of the waste and limit advective flow. A thorough understanding of buffer and seal evolution is required to make sure the safety functions are fulfilled in the short and long term. Experiments at the real or near-real scale taking into account the interaction with the host rock help to make sure the safety-relevant processes are identified and understood and to show that laboratory-scale findings can be extrapolated to repository scale. Three large-scale experiments on buffer and seal properties performed in recent years at the Mont Terri rock laboratory are presented in this paper: The 1:2 scale HE-E heater experiment which is currently in operation, and the full-scale engineered barrier experiment and the Borehole Seal experiment which have been completed successfully in 2014 and 2012, respectively. All experiments faced considerable difficulties during installation, operation, evaluation or dismantling that required significant effort to overcome. The in situ experiments show that buffer and seal elements can be constructed meeting the expectations raised through small-scale testing. It was, however, also shown that interaction with the host rock caused additional effects in the buffer or seal that could not always be quantified or even anticipated from the experience of small-scale tests (such as re-saturation by pore-water from the rock, interaction with the excavation damaged zone in terms of preferential flow or mechanical effects). This led to the conclusion that testing of the integral system buffer/rock or seal/rock is needed. (authors)

"I" play a role shifting from a calm narrator to a furious one, and the last recovering to a mild one, which offers a multiple visual angle to observe humanity. In sum, by means of continuous changes of my inner feelings in the poem, Pablo Neruda reveals the paradoxical humanity .

    The discussion of cultural and sociological consequences of computer evolution is hindered by human prejudice. For example the sentence 'a computer is at best as intelligent as its programmer' veils actual developments. Theoretical limits of computer intelligence are the limits of intelligence in general. Modern computer systems replace not only human labour, but also human decision making and thereby human responsibility. The historical situation is unique. Human head-work is being automated and man is loosing function. (orig.) [de

    Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

  7. Man-machine supervision

    2005-01-01

    Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

    The excavation damaged zone (EDZ) around the backfilled underground structures of a geological repository represents a release path for radionuclides, which needs to be addressed in the assessment of long-term safety. Additionally, the EDZ may form a highly efficient escape route for corrosion and degradation gases, thus limiting the gas overpressures in the backfilled repository structures. The efficiency of this release path depends not only on the shape and extent of the EDZ, but also on the self-sealing capacity of the host rock formation and the prevailing state conditions, such as in situ stresses and pore pressure. The hydro-mechanical and chemico-osmotic phenomena associated with the formation and temporal evolution of the EDZ are complex, thus precluding a detailed representation of the EDZ in conventional modelling tools for safety assessment. Therefore, simplified EDZ models, able to mimic the safety-relevant functional features of the EDZ in a traceable manner are required. In the framework of the Mont Terri Project, a versatile modelling approach has been developed for the simulation of flow and transport processes along the EDZ with the goal of capturing the evolution of hydraulic significance of the EDZ after closure of the backfilled underground structures. The approach draws on both empirical evidence and experimental data, collected in the niches and tunnels of the Mont Terri rock laboratory. The model was benchmarked with a data set from an in situ self-sealing experiment at the Mont Terri rock laboratory. This paper summarises the outcomes of the benchmark exercise that comprises relevant empirical evidence, experimental data bases and the conceptual framework for modelling the evolution of the hydraulic significance of the EDZ around a backfilled tunnel section during the entire re-saturation phase.

    The Full-Scale Emplacement (FE) Experiment at the Mont Terri underground research laboratory in Switzerland is a full-scale heater test in a clay-rich formation (Opalinus Clay). Based on the Swiss disposal concept it simulates the construction, emplacement, backfilling, and post-closure thermo-hydro-mechanical (THM) evolution of a spent fuel / vitrified high-level waste (SF / HLW) repository tunnel in a realistic manner. The main aim of this experiment is to investigate SF / HLW repository-induced THM coupled effects mainly in the host rock but also in the engineered barrier system (EBS), which consists of bentonite pellets and blocks. A further aim is to gather experience with full-scale tunnel construction and associated hydro-mechanical (HM) processes in the host rock. The entire experiment implementation (in a 50 m long gallery with approx. 3 m diameter) as well as the post-closure THM evolution will be monitored using a network of several hundred sensors (state-of-the-art sensors and measurement systems as well as fiber-optic sensors). The sensors are distributed in the host rock's near- and far-field, the tunnel lining, the EBS, and on the heaters. The heater emplacement and backfilling has not started yet, therefore only the host rock instrumentation is installed at the moment and is currently generating data. We will present the instrumentation concept and rationale as well as the first monitoring results of the excavation and ventilation phase. In particular, we investigated the excavation induced hydraulic response of the host rock. Therefore, the spatiotemporal evolution of porewater-pressure time series was analyzed to get a better understanding of HM coupled processes during and after the excavation phase as well as the impact of anisotropic geomechanic and hydraulic properties of the clay-rich formation on its hydraulic behavior. Excavation related investigations were completed by means of inclinometer data to characterize the non-elastic and time

  16. Pathways to man

    Harley, J.H.

    1980-01-01

    The study of radionuclide pathways leading to man generally has the goal of allowing us to predict human exposure from measurements of the radionuclide concentration in some segment of the environment. This modelling process provides a valuable tool in both the regulatory and health protection fields. However, most of the models in the regulatory field and in the health physics profession were designed to maximize exposure estimates. It is preferable to have scientifically defensible estimates and to add suitable safety factors at the end. Thus we are still faced with the development and validation of suitable models for many of the radionuclides of interest. The most useful models will include means of assessing variability and uncertainty. In this case variability might be considered as the differences in behavior due to age, sex or other factors in animals or man and those differences among plant species or animal species that determine their uptake factors. The uncertainty, on the other hand, would be the estimate of possible error in the experimental measurements. Model parameters would always have some variability even for site-specific cases and broad averages for population groups would have to include a factor expressing the possible variabilty and uncertainity. Thus any exposure calculation would have to be expressed with some range and valid assessments of this range are required

    A new and exciting discipline of human ecology is in the making. It has not, perhaps fortunately, found its bearings yet and remains to date overly dependent upon the limitations of sociology, biology, engineering and the sciences for its general theory, approaches, and philosophy. A new discipline with a world view and focussed on the human being and his habitat will hopefully emerge from a rich dialectic among scientists, humanists and policy makers educated and experienced in a variety of fields and committed to man's welfare. This new discipline and its practitioner must always be open to the revelations their knowledge will bring to man through the environmental processes. The implications of public policy, science and technology of industrial and post-industrial nations are all in need of considered re-examination by us all. Since their early application in these western societies we have witnessed the general downgrading of the world's environment. An ungrading in social priorities for the development of adequate housing, jobs, medical care and education which is almost always lower in rank than they should be is needed. The role of local groups, involving a well-informed and participating citizenship, in this process of changing priorities will always remain of prime importance, but no long-range goal in a rapidly-changing landscape is possible without broad national and local planning which contains ways and means of implementation.

    This article described the 2 opposing views in 1958 regarding how the big Montreal refinery market should be served. While the president of Imperial Oil expressed that Montreal refineries should not be forced to use domestic feedstocks, Alberta Premier Ernest Manning urged the Borden Commission to take immediate measures to expand the market for Canadian crude oil into Montreal. Manning argued that the dependence on Venezuelan crude in the Montreal refining market would pose a danger to the stability and development of the oil industry; loss of revenue for municipal, provincial and federal governments; and, an adverse effect on Canada's trade balance with the United States. The Premier suggested that these problems could be avoided by expanding the market for Canadian crude in Ontario and Quebec, in the U.S. Midwest, and in the Pacific Northwest. In 1958, the Canadian oil industry was divided on the Montreal market issue. Other key events in 1958 were listed. Waterton was characterized as Canada's biggest gas field, with reserves of 3 trillion cubic feet. A gas discovery at Berland River was considered the largest single-well exploration find in the world, flowing 27 million cubic feet per day on 1 drillstem. Two new refineries near Vancouver and Toronto were built to raise Canadian refining capacity to 813,000 barrels per day. 1 tab., 1 fig

    The ventilation of the underground drifts during the construction and operation of a radioactive waste repository could produce the partial desaturation of the rock around the drifts, modifying its thermo-hydro-mechanical properties, especially in clayey rocks. This change of rock properties may have an impact on the design of the repositories (drifts spacing and repository size), which depends on the thermal load that the clay barrier and the rock can accept. To evaluate 'in situ' and better understand the desaturation process of a hard clay formation, the Ventilation Experiment (VE) has been carried out at the Mont Terri underground laboratory (Switzerland), generating a flow of dry air during several months along a section of a microtunnel. Specifically, the VE test has been performed, under practically isothermal conditions (T {approx_equal} 15-16 {sup o}C), in a 10 m long section of a non-lined horizontal microtunnel (diameter = 1.3 m), excavated in 1999 in the shaly facies of the Opalinus Clay of Mont Terri. The microtunnel is oriented perpendicular to the bedding strike direction of the rock (mean value of the bedding dip {approx_equal} 25{sup o}). The VE experiment real data and its modelling have shown that the desaturation of clayey rocks of low hydraulic conductivity (K < 10{sup -12} m/s) due to ventilation is very small. Under real repository conditions, the thermal and hydro-mechanical rock characteristics will not be practically affected by the ventilation. Specifically, the monitoring of the VE test (mainly the hygrometer data, confirmed also by the geoelectrical measurements) indicates that, after about 5 months of ventilation with almost dry air, the rock relative humidity (and then the degree of saturation) was less than 95% only in a ring of thickness less than 40 cm. Nevertheless, a suction state (subatmospheric liquid pressures) developed up to a distance of about 2 m, but it should be kept in mind that a clayey rock such as the

    Document available in extended abstract form only. The Mont Terri rock laboratory was extended from mid October 2007 to end 2008 with the goal to allow the project partners to continue their cooperative research on the long term. The extension of the underground laboratory by the excavation of an additional 165 metres long access tunnel (Gallery 08) with four niches was taken as opportunity to conduct an instrumented mine-by test in one of the niches (Niche 2/Niche MB). The measurements during the bedding parallel excavation provided a large amount of data as a basis to understand the hydro-mechanical (HM) coupled behaviour of Opalinus Clay around the excavated niche. BGR was involved in the in-situ investigations (seismic measurements) as a member of the experiment team consisting of five organisations (incl. NAGRA, ANDRA, GRS, Obayashi). An important issue for BGR is the application of the numerical code RockFlow (RF) for HM coupled simulations in order to understand the behaviour of Opalinus Clay by the use of the gained measuring data for validation. Under the management of NAGRA a blind prediction was carried out for a group of modelers belonging to some of the experiment team organisations. After a first comparison between the numerical results of different HM coupled models during the prediction meeting of the teams in June 2009 the measurement data are provided by NAGRA in order to validate the numerical models. Basically the model predictions have already shown the correct tendencies and ranges of observed deformation and pore water pressure evolution besides some under- or overestimations. The future RF validation results after having done some slight parameter adjustments are intended to be presented in the paper. The excavation of Niche 2 was done from 13 October to 7 November 2008 with a constant excavation rate of 1.30 m per day. The orientation of the niche follows the bedding strike, which amounts 60 deg.. The bedding planes have an average dip of

    This paper is reassessment of an old method improved by well-directed application of well-known maneuvers of laryngo-pharyngeal function. Although not as visually attractive as a dedicated laryngogram (now hardly ever requested), it does render similarly reliable diagnostic information, which, supported, as occasionally necessary, by conventional tomography, can even surpass that given by the older technique. Its main advantage lies in providing cheap, quick, noninvasive studies with minimal descomfort for the patient. Should further investigation be necessary, for analysis of deep extension, modern cross-sectional imaging methods (especially MR) far surpass even dedicated laryngography in diagnostic value and can be based adequately on 'poor mans's laryngography'. Ways in which this method may be optimised, especially those involving laryngopharyngeal function, are briefly presented - with emphasis on relevant practical aspects - as are normal and abnormal findings.

    Document available in extended abstract form only. Exploration of deep subsurface microbial life has increased for very diverse motives. One of them is that these environments are potential host rocks for radioactive waste repositories and that microorganisms may influence geochemical conditions around such sites and migration properties of radionuclides. The pore water Chemistry experiment (PC) was conducted at the Mont Terri-RL to measure in situ the pH, Eh, and other geochemical parameters within the pore water of the Opalinus Clay formation. The borehole for PC was drilled with N 2 under clean but not aseptic conditions, filled immediately with synthetic pore water, which was circulated and monitored for five years. Soon after initiation of PC it was evident that microbial activity affected the borehole water geochemistry. Microbial analyses, including molecular biology and culturing methods, were performed repeatedly during PC (2003-2006), with detailed analysis of water and over-core clay upon termination in 2007. Results indicated the presence of heterotrophic aerobes and anaerobes, nitrate-reducers, iron-reducers, sulphate-reducers and Archaea, which together with geochemical data suggested a reducing environment with sulphate reduction in the water and adjacent clay. A black precipitate containing pyrite and a strong H 2 S smell confirmed the occurrence of sulphate reduction. Specific species identified (> 98% similarity) in PC water included Pseudomonas stutzeri, Bacillus licheniformis, and Desulfosporosinus sp., with similar and additional species (e.g., Trichococcus sp.; Koccuria sp.) in the clay. The origin of these (mostly anaerobic) species cannot be determined with certainty. Some species likely resulted from contamination, but others could be revived species indigenous in the Opalinus Clay. The microbial processes that occurred in PC are not representative of the processes in the undisturbed formation but illustrate the potential for microbial

    Böse, Margot; Brande, Arthur

    2010-10-01

    The Bäke creek valley is part of the young morainic area in Berlin. Its origin is related to meltwater flow and dead-ice persistence resulting in a valley with a lake-creek system. During the Late Glacial, the slopes of the valley were affected by solifluction. A Holocene brown soil developed in this material, whereas parts of the lakes were filled with limnic-telmatic sediments. The excavation site at Goerzallee revealed Bronze Age and Iron Age burial places at the upper part of the slope, as well as a fireplace further downslope, but the slope itself remained stable. Only German settlements in the 12th and 13th centuries changed the processes in the creek-lake system: the construction of water mills created a retention system with higher ground water levels in the surrounding areas. On the other hand, deforestation on the till plain and on the slope triggered erosion. Therefore, in medieval time interfingering organic sediments and sand layers were deposited in the lower part of the slope on top of the Holocene soil. The new soil which formed on top of these sediments was transformed by ploughing until the 19th century.

  10. REMO poor man's reanalysis

    Reanalyses depict the state of the atmosphere as a best fit in space and time of many atmospheric observations in a physically consistent way. By essentially solving the data assimilation problem in a very accurate manner, reanalysis results can be used as reference for model evaluation procedures and as forcing data sets for different model applications. However, the spatial resolution of the most common and accepted reanalysis data sets (e.g. JRA25, ERA-Interim) ranges from approximately 124 km to 80 km. This resolution is too coarse to simulate certain small scale processes often associated with extreme events. In addition, many models need higher resolved forcing data ( e.g. land-surface models, tools for identifying and assessing hydrological extremes). Therefore we downscaled the ERA-Interim reanalysis over the EURO-CORDEX-Domain for the time period 1989 to 2008 to a horizontal resolution of approximately 12 km. The downscaling is performed by nudging REMO-simulations to lower and lateral boundary conditions of the reanalysis, and by re-initializing the model every 24 hours ("REMO in forecast mode"). In this study the three following questions will be addressed: 1.) Does the REMO poor man's reanalysis meet the needs (accuracy, extreme value distribution) in validation and forcing? 2.) What lessons can be learned about the model used for downscaling? As REMO is used as a pure downscaling procedure, any systematic deviations from ERA-Interim result from poor process modelling but not from predictability limitations. 3.) How much small scale information generated by the downscaling model is lost with frequent initializations? A comparison to a simulation that is performed in climate mode will be presented.

    The characteristics of opalinus clay have been studied in the last years for its capacity to retain radionuclide transport as a low permeable rock. This formation presents thereby suitable properties for hosting repository sites of radioactive waste. The Mont Terri underground rock laboratory (Switzerland) has been excavated in opalinus clay layer in order to develop experiences improving the knowledge on the physico-chemical properties of the rock. The study of electrical properties furnishes information on the rock structure, its anisotropy and the changes of these properties with time (Nicollin et al., 2010 ; Thovert et al., 2011). Here the three dimensional reconstruction of the electrical resistivity aims at monitoring the temporal evolution of the excavation damaged zone. Three rings of electrodes have been set-up around the gallery and voltage is measured between two electrodes while a current is injected between two others (Gibert et al., 2006). Measurements have been achieved from July 2004 until April 2008 before, during and after the excavation of the gallery 04. In this study we develop a computational approach to reconstruct three dimensional images of the resistivity in the vicinity of the electrodes. A finite element model is used to represent the complex geometry of the gallery. The measurements inferred from a given resistivity distribution are estimated using the software EIDORS (Adler and Lionheart, 2006), this constitutes the forward problem. The reconstruction of the media resistivity is then implemented by fitting the estimated to the measured data, via the resolution of an inverse problem. The parameters of this inverse problem are defined by mapping the forward problem elements into a coarser mesh. This allows to reduce drastically the number of unknowns and so increases the robustness of the inversion. The inversion is executed with the conjugate gradient method regularised by an analysis of the Jacobian singular values. The results show an

    The present study tested and extended Lane and Terry (2000) conceptual model of mood-performance relationships using a large dataset from an online experiment. Methodological and theoretical advances included testing a more balanced model of pleasant and unpleasant emotions, and evaluating relationships among emotion regulation traits, states and beliefs, psychological skills use, perceptions of performance, mental preparation, and effort exerted during competition. Participants ( N = 73,588) completed measures of trait emotion regulation, emotion regulation beliefs, regulation efficacy, use of psychological skills, and rated their anger, anxiety, dejection, excitement, energy, and happiness before completing a competitive concentration task. Post-competition, participants completed measures of effort exerted, beliefs about the quality of mental preparation, and subjective performance. Results showed that dejection associated with worse performance with the no-dejection group performing 3.2% better. Dejection associated with higher anxiety and anger scores and lower energy, excitement, and happiness scores. The proposed moderating effect of dejection was supported for the anxiety-performance relationship but not the anger-performance relationship. In the no-dejection group, participants who reported moderate or high anxiety outperformed those reporting low anxiety by about 1.6%. Overall, results showed partial support for Lane and Terry's model. In terms of extending the model, results showed dejection associated with greater use of suppression, less frequent use of re-appraisal and psychological skills, lower emotion regulation beliefs, and lower emotion regulation efficacy. Further, dejection associated with greater effort during performance, beliefs that pre-competition emotions did not assist goal achievement, and low subjective performance. Future research is required to investigate the role of intense emotions in emotion regulation and performance.

    Document available in extended abstract form only. In the Mont Terri Underground Rock Laboratory, the excavation of the new gallery Ga08 provided a unique opportunity to monitor the excavation damaged zone (EDZ) in the Opalinus clay, at time scales ranging from hours to months. The excavation of the gallery Ga08 has started from the northern end of the URL and has progressed towards the South, ending by the junction with the end of the gallery Ga04. Several geophysical and geochemical methods were performed from the end face of the gallery Ga04, to observe the evolution of the rock mass located in the so-called EZ-G08 section during the progress of the excavation. Thus, electrical resistivity measurements were performed, with electrodes placed both on the Ga04 face and in boreholes perpendicular to the face. These experiments revealed a strong anisotropy of the electrical resistivity of the rock mass, and they allowed to study the temporal evolution of the electrical resistivity in the EDZ. An array of more than 700 electrodes was installed on the rough face according to a square mesh with a mean side of 30 cm. On each line of the mesh, the electrodes were equally spaced every 15 cm. 4 horizontal boreholes, 8 m long and 56 mm in diameter, were equipped with lines of 64 electrodes equally spaced every 5 cm. Finally, 2 groups of 4 boreholes, 1 m long and spaced about 20 cm, were equipped with lines of 16 electrodes equally spaced every 5 cm. Using the electrode array of the face, Wenner profiles were acquired along both the horizontal and the vertical lines, highlighting a strong anisotropy of electrical resistivity since the values depend on the direction in which they are measured. In order to characterize this anisotropy, other measurements were done using the array of the face and the lines of the short boreholes, with the so-called square array configuration where the electrodes are located at the corners of squares with different orientations.

    The Engineered Barrier (EB) experiment was a full-scale test for the demonstration, in a horizontal drift, of an emplacement technics of the clay barrier, using a granular bentonite material in the upper part of this barrier and bentonite blocks at the bottom. The test has been carried out in a 6 m long section of a niche excavated in Opalinus Clay of the Mont Terri underground laboratory. A steel dummy canister, with the same dimensions and weight as the real reference canisters, was placed on top of a bed of highly compacted bentonite blocks (in turn lying on a concrete bed), and the rest of the clay barrier volume was backfilled with a Granular Bentonite Material (GBM), made of very highly compacted pellets of different sizes. Hydro-mechanical instrumentation and an artificial hydration system (to accelerate the saturation of the clay barrier) were installed, and the test section sealed with a concrete plug. The evolution of the hydro-mechanical parameters along the hydration, both in the barrier and in the clayey rock formation, has been monitored during about 1.5 years, and modelled using the CODE-BRIGHT code. The EB experiment has proved that fully automated production of a Granular Bentonite Material (GBM) is possible and large quantities can be produced in due time in the required quality. Only minor modifications of existing production lines in industry for other applications were necessary to achieve this result. In the EB test section, a dry density of 1.36 g/cm 3 of the emplaced GBM has been obtained. With this value it is estimated that the hydraulic conductivity of this material is lower than 5 x 10 -12 m/s and the swelling pressure is about 1.3 MPa. Even though the EB test section conditions are now not considered as representative of a true demonstration, it is deemed that the model emplacement testing results (dry density of about 1.40 g/cm 3 ) serve well to demonstrate the achievable densities expected in the real world setting.

    Highlights: > Equilibrium models of water-rock reactions in clay rocks are reviewed. > Analyses of pore waters of the Opalinus Clay from boreholes in the Mont Terri URL, Switzerland, are tabulated. > Results of modelling with various mineral controls are compared with the analyses. > Best agreement results with calcite, dolomite and siderite or daphnite saturation, Na-K-Ca-Mg exchange and/or kaolinite, illite, quartz and celestite saturation. > This approach allows calculation of the chemistry of pore water in clays too impermeable to yield water samples. - Abstract: The chemistry of pore water (particularly pH and ionic strength) is an important property of clay rocks being considered as host rocks for long-term storage of radioactive waste. Pore waters in clay-rich rocks generally cannot be sampled directly. Instead, their chemistry must be found using laboratory-measured properties of core samples and geochemical modelling. Many such measurements have been made on samples from the Opalinus Clay from the Mont Terri Underground Research Laboratory (URL). Several boreholes in that URL yielded water samples against which pore water models have been calibrated. Following a first synthesis report published in 2003, this paper presents the evolution of the modelling approaches developed within Mont Terri URL scientific programs through the last decade (1997-2009). Models are compared to the composition of waters sampled during dedicated borehole experiments. Reanalysis of the models, parameters and database enabled the principal shortcomings of the previous modelling efforts to be overcome. The inability to model the K concentrations correctly with the measured cation exchange properties was found to be due to the use of an inappropriate selectivity coefficient for Na-K exchange; the inability to reproduce the measured carbonate chemistry and pH of the pore waters using mineral-water reactions alone was corrected by considering clay mineral equilibria.

    The German Federal Government has announced that research and development activities concerning final repositories for high-level waste are to focus on clay formations as host rock in order to investigate alternatives to salt rock which is favoured in the current reference concept. Within the scope of design calculations for a final repository in clay formations, thermohydro-mechanical interaction effects have thus been studied, but only based on numerical calculation. The currently preferred disposal concept is based on the emplacement of heat-generating waste in vertical boreholes with a depth of 50 m maximum. How strongly thermally induced interaction between adjacent emplacement boreholes affects a system of vertical boreholes in claystone has not yet been investigated in-situ. However, these interaction effects need to be considered as in a real repository the emplacement boreholes are drilled successively and, depending on the delivery and necessary cooling-off time of the containers at the interim storage facility, are filled at corresponding intervals. The main goal of the suggested in-situ experiment is to investigate the THM interaction of two adjacent emplacement boreholes that are filled and heated at different times. The project is to be planned and carried out jointly by DBE TECHNOLOGY GmbH and GRS. The Federal Institute for Geosciences and Natural Resources (GBR) has declared its interest in participating. A location for this experiment has been found at the underground research laboratory in Mont Terri, Switzerland, which is located in an Opalinus-clay formation. The project has been presented to the Mont Terri consortium, and a positive vote to carry out the experiment was obtained. The exact location of the experiment has been set within the so-called ''sandy facies'' of the rock lab which is similar to the German part of the Opalinus clay. Since time and costs involved in such a major project cannot be reliably estimated

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason.

Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analog...

    Full Text Available The attitudes and beliefs that archaeologists bring to their profession can have important impacts upon the manner in which they approach their work; therefore, studying an archaeologist’s life can shed light on archaeological history. An investigation of the early life of the Mexican archaeologist Alberto Ruz Lhuillier provides fascinating evidence of just how life experiences can have an impact on attitudes and theoretical approaches. Ruz was the archaeologist who, in 1952, discovered the magnificent tomb of the Classic Maya King of Palenque, Mexico, K’inich Janaab’ Pakal I. Research into Ruz’s early life sheds light on why he had negative opinions about the United States (US, and highlights the experiences that caused them, and explains how they changed. When Ruz moved to Cuba in the 1930s, and learned about the impact of American interference in Cuban affairs, he became deeply involved in the socialist revolution to oust Cuba’s US puppet dictators and to free his country from ‘yanqui’ imperialism. In addition, these early student life experiences exposed him to other students who espoused the theories and ideas of Karl Marx. Later Ruz would use some of these theories to explain the development and fall of ancient Maya civilization.

    Full Text Available Friedebert Tuglas’ Felix Ormusson and James Joyce’s Portrait of the Artist as a Young Man were finished in the same year – 1914, but the writing of both novels took the writers almost a decade, a time of searching and exile for both of them. Joyce completely rewrote the initial draft of his novel, entitled Stephen Hero, experimenting with basic forms, such as the short prose piece he called the ”epiphany”. Tuglas’ Felix Ormusson was initially conceived as a three-volume picaresque novel, which was distilled into a single volume of prose fragments arranged as a diary novel: the rest was left unfinished, and exists only in the form of two novella-length fragments. A comparative juxtaposition of the two novels is suggestive, not just because of parallels between the authors’ life trajectories and creative biographies, nor because of similarities between the protagonists, not even by the somewhat deceptive placement in the rubric of the 'Künstlerroman'. Both novels partake of ironic autobiography, and both resonate with the subgenre of the ”diary novel”, increasingly in vogue in European literature of the fin-de-siècle, modelled in turn on the published journal intime. Felix Ormusson and Stephen Dedalus were their authors’ long-time fictional fellow travellers, alter ego’s, in whose confessions one can read the pressing desire to emerge from the provinces and peripheries of Europe toward broader, metropolitan cultural horizons. The protagonists’ quests open onto the problematics of modernism – the split between life and literature, and the burden of ”overreflexivity” which obstructed literary creation and sentimental education. Behind the aesthetic polemics of both novels are shadows of the politics of the era: for Felix Ormusson, the aftermath of the 1905 revolution and political exile, and in the milieu of young Stephen Dedalus, the entanglement of national politics and the Catholic church.

    Several years ago, GRS performed laboratory investigations on the suitability of clay/mineral mixtures as optimized sealing materials in underground repositories for radioactive wastes /JOC 00/ /MIE 03/. The investigations yielded promising results so that plans were developed for testing the sealing properties of those materials under representative in-situ conditions in the Mont Terri Rock Laboratory (MTRL). The project was proposed to the ''Projekttraeger Wassertechnologie und Entsorgung (PtWT+E)'', and finally launched in January 2003 under the name SB-project (''Self-sealing Barriers of Clay/Mineral Mixtures in a Clay Repository''). The project was divided in two parts, a pre-project running from January 2003 until June 2004 under contract No. 02E9713 /ROT 04/ and the main project running from January 2004 until June 2012 under contract No. 02E9894 with originally PtWT+E, later renamed as PTKA-WTE. In the course of the pre-project it was decided to incorporate the SB main project as a cost shared action of PtWT+E and the European Commission (contract No. FI6W-CT-2004-508851) into the EC Integrated Project ESDRED (Engineering Studies and Demonstrations of Repository Designs) performed by 11 European project partners within the 6th European framework programme. The ESDRED project was terminated prior to the termination of the SB project. Interim results were reported by mid 2009 in two ESDRED reports /DEB09/ /SEI 09/. This report presents the results achieved in the whole SB-project comprising preceding laboratory investigations for the final selection of suited material mixtures, the conduction of mock-up tests in the geotechnical laboratory of GRS in Braunschweig and the execution of in-situ experiments at the MTRL.

    At the Mont Terri rock laboratory (Switzerland), an in situ experiment is being carried out to examine the fate of nitrate leaching from nitrate-containing bituminized radioactive waste, in a clay host rock for geological disposal. Such a release of nitrate may cause a geochemical perturbation of the clay, possibly affecting some of the favorable characteristics of the host rock. In this in situ experiment, combined transport and reactivity of nitrate is studied inside anoxic and water-saturated chambers in a borehole in the Opalinus Clay. Continuous circulation of the solution from the borehole to the surface equipment allows a regular sampling and online monitoring of its chemical composition. In this paper, in situ microbial nitrate reduction in the Opalinus Clay is discussed, in the presence or absence of additional electron donors relevant for the disposal concept and likely to be released from nitrate-containing bituminized radioactive waste: acetate (simulating bitumen degradation products) and H{sub 2} (originating from radiolysis and corrosion in the repository). The results of these tests indicate that - in case microorganisms would be active in the repository or the surrounding clay - microbial nitrate reduction can occur using electron donors naturally present in the clay (e.g. pyrite, dissolved organic matter). Nevertheless, non-reactive transport of nitrate in the clay is expected to be the main process. In contrast, when easily oxidizable electron donors would be available (e.g. acetate and H{sub 2}), the microbial activity will be strongly stimulated. Both in the presence of H{sub 2} and acetate, nitrite and nitrogenous gases are predominantly produced, although some ammonium can also be formed when H{sub 2} is present. The reduction of nitrate in the clay could have an impact on the redox conditions in the pore-water and might also lead to a gas-related perturbation of the host rock, depending on the electron donor used during denitrification

    We studied gouge from an upper-crustal, low-offset reverse fault in slightly overconsolidated claystone in the Mont Terri rock laboratory (Switzerland). The laboratory is designed to evaluate the suitability of the Opalinus Clay formation (OPA) to host a repository for radioactive waste. The gouge occurs in thin bands and lenses in the fault zone; it is darker in color and less fissile than the surrounding rock. It shows a matrix-based, P-foliated microfabric bordered and truncated by micrometer-thin shear zones consisting of aligned clay grains, as shown with broad-ion-beam scanning electron microscopy (BIB-SEM) and optical microscopy. Selected area electron diffraction based on transmission electron microscopy (TEM) shows evidence for randomly oriented nanometer-sized clay particles in the gouge matrix, surrounding larger elongated phyllosilicates with a strict P foliation. For the first time for the OPA, we report the occurrence of amorphous SiO2 grains within the gouge. Gouge has lower SEM-visible porosity and almost no calcite grains compared to the undeformed OPA. We present two hypotheses to explain the origin of gouge in the Main Fault: (i) authigenic generation consisting of fluid-mediated removal of calcite from the deforming OPA during shearing and (ii) clay smear consisting of mechanical smearing of calcite-poor (yet to be identified) source layers into the fault zone. Based on our data we prefer the first or a combination of both, but more work is needed to resolve this. Microstructures indicate a range of deformation mechanisms including solution-precipitation processes and a gouge that is weaker than the OPA because of the lower fraction of hard grains. For gouge, we infer a more rate-dependent frictional rheology than suggested from laboratory experiments on the undeformed OPA.

    The available evidence on the effects of radiation on man and the predictions that have been made of possible low level effects are reviewed. Data from United Nations Scientific Committee of the Effects of Atomic Radiation (UNSCEAR) and the committee on the Biological Effects of Ionising Radiation (BEIR) is used to illustrate the acute, delayed and hereditary effects of high dose levels. The effects of low dose levels are discussed on the assumption that both somatic and hereditary effects can be predicted on the basis of linear extrapolation from high dose effects. (U.K.)

    Full Text Available In an attempt to test the conceptual model by Lane and Terry, the purposes of this study were 1 to assess mood states in non-depressed and depressed young karate athletes; 2 to assess mood states in relation to performance in young karate athletes. The participants were recruited from the 2004 Malaysian Games (72 males, 19.20 ± 1.16 years; 37 females, 18.78 ± 0.88 years. The athletes were divided into winners (medalists and losers. The Brunel Mood Scale (BRUMS was administered prior to the start of competition. MANOVA was employed to treat the data, while Pearson correlations were calculated for mood states in each depressed mood group and by gender. In terms of non-depressed and depressed mood, tension in the females was higher in the depressed group (5.61 ± 3.02 vs. 3.11 ± 1.90, p = 0.026, eta2 = 0.133, as was fatigue (3.64 ± 2.61 vs. 0.89 ± 1.69, p = 0.006, eta2 = 0.199. Tension in the males was higher in the depressed group (4.41 ± 2.52 vs. 1.50 ± 1.55, p < 0.001, eta2 = 0.215, as was anger (1.43 ± 1.88 vs. 0.25 ± 1.00, p = 0.019, eta2 = 0.076. The highest associations among mood subscales were between anger and depression (r = 0.57, and between depression and fatigue ( r = 0.55 in depressed males. The female winning karateka scored higher on anger (3.08 ± 2.96 vs. 1.29 ± 2.24, p = 0.046, eta2 = 0.109. The highest correlations between mood dimensions in depressed females were between depression and anger (r = 0.85 and between depression and confusion (r = 0.85. Contrary to previous research on the influence of depression on anger, only the female winners scored higher on anger. Several negative mood dimensions were higher in both male and female depressed groups, lending some support to the conceptual model advanced by Lane and Terry

    Marie Curie was awarded the Nobel Prize in chemistry 1911. During the preceding year a rumour had circulated in Stockholm that she had had an affaire with one of her assistants. She received a letter, in which she was told that there had been strong opposition to her election not on scientific but moral grounds, and that she should not go to Stockholm, because nobody could forsee what reactions her appearance at the prize ceremony could evoke. Emil Kleen, a man of violent temper and radical opinions, reacted strongly to these rumours. He wrote a paper, with a violent attack on Gustaf Retzius, previous professor of Histology at Karolinska Institutet. Rightly or wrongly he suspected him to be the author of the infamous letter. Retzius is described as a dilletant in scientific matters, as a "sexual hyena" and a garroulus old man. This portrait of Retzius is of course most unfair, but the portrait of Emil Kleen by the famous swedish artist Bruno Liljefors is a masterpiece and one of the most valuable of the Swedish Medical Association.

  14. The rights of man and animal experimentation.

    Science.gov (United States)

    Martin, J

    1990-01-01

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity. PMID:2135948

The conciliation assembly highlights the contributions made by two specific documents: the Religious Liberty Decree and the Declaration regarding Non-Christian Religions. The assembly also suggests some lines to reflect about religious liberty in a discussion among diverse religious organizations.

  16. Physico-chemical characterisation and sorption measurements of Cs, Sr, Ni, Eu, Th, Sn and Se on Opalinus clay from Mont Terri

    2000-12-01

    Opalinus Clay is currently under investigation as a potential host rock for the disposal of high level and long-lived intermediate radioactive waste. A throughout physico-chemical characterisation was carried out on a bore core sample from the underground rock laboratory Mont Terri (Canton Jura). The results of these investigations indicate that the major characteristics (mineralogy, cation exchange capacity, cation occupancies, selectivity coefficients, chloride and sulphate inventories) were very similar to a different core sample, previously used for pore water modelling studies. It was concluded that the pore water compositions derived in the earlier studies were reliable and could be used in this work. The organic matter which dissolved from the Opalinus Clay rock was not humic or fulvic acids and the concentration remaining in the liquid phase in the sorption experiments was < 0.5 ppm C. The organic matter is therefore considered to have little or no influence on the sorption behaviour of the studied radionuclides. Redox potential measurements of the Opalinus Clay/synthetic pore water system inside the glove boxes indicated anoxic conditions. The main focus of the experimental work presented here is on the sorption behaviour of Cs (I), Sr (II), Ni (II), Eu (III), Th (IV), Sn (IV) and Se (IV) on Opalinus Clay equilibrated with synthetic pore waters at pH 6.3 and 8. Sorption isotherms were measured for Cs, Ni, Eu, Th and Se. Single point data were measured for Sr and Sn. For all radionuclides studied the sorption kinetics were measured first. The times required to complete the sorption on the Opalinus Clay varied between one day for Th and one month for Ni and Se. Within the concentration ranges under study the uptake of Cs, Ni, Eu and Se on Opalinus Clay was non-linear, whereas for Th a linear sorption behaviour was observed. For Ni, Eu and Th the sorption increased with increasing pH. For Cs a pH independent sorption behaviour was observed. The concentration

    Data pertinent to pore-water composition in Opalinus Clay in the Mont Terri and Mont Russelin anticlines have been collected over the last 20 years from long-term in situ pore-water sampling in dedicated boreholes, from laboratory analyses on drill cores and from the geochemical characteristics of vein infills. Together with independent knowledge on regional geology, an attempt is made here to constrain the geochemical evolution of the pore-waters. Following basin inversion and the establishment of continental conditions in the late Cretaceous, the Malm limestones acted as a fresh-water upper boundary leading to progressive out-diffusion of salinity from the originally marine pore-waters of the Jurassic low-permeability sequence. Model calculations suggest that at the end of the Palaeogene, pore-water salinity in Opalinus Clay was about half the original value. In the Chattian/Aquitanian, partial evaporation of sea-water occurred. It is postulated that brines diffused into the underlying sequence over a period of several Myr, resulting in an increase of salinity in Opalinus Clay to levels observed today. This hypothesis is further supported by the isotopic signatures of SO{sub 4}{sup 2-} and {sup 87}Sr/{sup 86}Sr in current pore-waters. These are not simple binary mixtures of sea and meteoric water, but their Cl{sup -} and stable water-isotope signatures can be potentially explained by a component of partially evaporated sea-water. After the re-establishment of fresh-water conditions on the surface and the formation of the Jura Fold and Thrust Belt, erosion caused the activation of aquifers embedding the low-permeability sequence, leading to the curved profiles of various pore-water tracers that are observed today. Fluid flow triggered by deformation events during thrusting and folding of the anticlines occurred and is documented by infrequent vein infills in major fault structures. However, this flow was spatially focussed and of limited duration and so did not

    Full text of publication follows: The Pore water Chemistry (PC-)experiment was initially designed to determine the processes that control the redox properties of pore water in the Opalinus Clay at the Mont Terri URL. However, changes in isotopic data and chemical parameters such as pH, alkalinity, dissolved methane, acetate and sulphate concentrations indicated unexpected microbial activity. The origin of the bacteria is not clear. In the light of published data, an indigenous origin cannot be ruled out. A combined biological and reactive transport model has been developed with the parallel PHAST software to simulate the processes that determine pore water chemistry. The influence of bacterial activity on the system is successfully modelled by considering different reaction pathways scenarios including aceto-genesis, methano-genesis, and methane/acetate oxidation coupled to sulphate reduction. Several conclusions can be clearly stated in the light of the simulation results: - The measured redox potentials (redox electrode) are in line with the S(-II)/S(+VI) redox system. - In the undisturbed pore water, S(-II) and S(+VI) activities are controlled by a mineral assemblage containing pyrite and a Fe carbonate (siderite or ankerite). pH is buffered by mineral phases and SO 4 2- concentration is inherited from the marine sedimentary rock. - Some local redox potentials in the sedimentary rock do not correspond to the measured redox potential; for instance, organic matter/HCO 3 - and CH 4 /HCO 3 - systems are not at equilibrium with the measured redox potential. - Redox disequilibrium can be exploited by micro-organisms as a source of energy for their metabolism. In this experiment CH 4 , acetate and other organic acids were produced and SO 4 2- was reduced to HS - . The redox properties of the system are then governed by kinetics rather than by thermodynamic equilibrium. The unexpected persistence of acetate in the borehole water is one of the consequences of these

    2011-01-01

    Cosmic muons are produced in cascade processes following the interactions of cosmic rays with the atmosphere. Muons are fundamental particles with a mass 200 times higher than electrons. Their low interaction probability with matter allows them to cross the atmosphere and even the first kilometers of the Earth crust. The muons flux is attenuated through a media as function of the quantity of matter crossed. The study of the muon flux attenuation allows then to obtain a direct measurement of the rock opacity. This opacity corresponds to the media density, integrated along the muon path through rock. Muons' trajectory is indeed considered to be straight when crossing rock. It is then possible to realise geophysical tomographies by setting a sensor network around geological objects in order to determine the internal structures geometry inside these objects. An underground muon flux model is developed herein from flux models estimated at surface and a model of muon flux attenuation through rock. A feasibility equation of the muon tomography is then established in order to determine the minimum time of data acquisition to distinguish heterogeneities. Four muons telescopes have been built during this thesis and conditioned to bear field installation, notably in tropical media. These telescopes are made by two or three matrices of detection constituted of scintillating bars linked to photomultipliers. The modeling of the telescopes detection capacity and angular resolution is realised as function of their geometrical configuration. A calibration method is also established in order to correct the signal from any distortion. Moreover, arrangements to reduce the backward noise produced by low energy particles are set up and evaluated. The development of this new tomographic method is then illustrated by two geophysical applications. The measurements realised in the Mont Terri underground laboratory (Switzerland) allowed us to benefit from stable acquisition conditions to

    1981-01-01

    Called a madman by some, a genius by others, and an enigma by nearly everyone, Nikola Tesla created astonishing, world-transforming devises that were virtually without theoretical precedent. Tesla not only discovered the rotating magnetic field, the basis of most alternating current machinery, but also introduced the fundamentals of robotry, computers, and missile science and helped pave the way for such technologies as satellites, microwaves, beam weapons, and nuclear fusion. Almost supernaturally gifted, Tesla was also unusually erratic, flamboyant, and neurotic. He was J. P. Morgan's client, counted Mark Twain as a friend, and considered Thomas Edison an enemy. But above all, he was the hero and mentor to many of the last century's most famous scientists. In a meticulously researched, engagingly written biography, Margaret Cheney presents the many different dimensions of this extraordinary man, capturing his human qualities and quirks as she chronicles a lifetime of discoveries that continue to alter our ...

    2012-07-01

    We introduce a framework for 3D object deformation with primary focus on man-made objects. Our framework enables a user to deform a model while preserving its defining characteristics. Moreover, our framework enables a user to set constraints on a model to keep its most significant features intact after the deformation process. Our framework supports a semi-automatic constraint setting environment, where some constraints could be automatically set by the framework while others are left for the user to specify. Our framework has several advantages over some state of the art deformation techniques in that it enables a user to add new features to the deformed model while keeping its general look similar to the input model. In addition, our framework enables the rotation and extrusion of different parts of a model.

    The Assistant Bishop of Manila, Philippines, comments on Pope John Paul II teachings and former Pope Paul VI's Humanae Vitae. The Roman Catholic Church over the past twenty five years has not accepted modern contraception. Lay Catholics are confused over the appropriate behavior regarding family planning, are ignorant of the Church's teachings, or have followed their conscience. Critics say that the teachings are obsolete and unheeded. Church officials respond that the Church is run by divine inspiration and not majority rule. The Church position is based on reason and on God himself, who prohibits man-made contraception. Paul VI revealed that the conjugal act was the link between unitive and procreative meanings, and man did not have the right to break the link on his own initiative. John Paul II reaffirms this position by stating that human beings do not have "absolute dominion over the conjugal act" and are not the final arbiters of the creation of life. Humans are servants of the creation of new life as collaborators and procreators. Humans act like Gods when they deprive the conjugal act of procreative meaning through contraceptive use. Natural family planning does not violate this divine prerogative. The Pope's teachings are verified. There is evidence of declines in conjugal infidelity, the lowering of moral standards, increased abortion, and the demise of demographic imperialism. The Church recognizes the problem of overpopulation, and the Catholic Bishops Conference of the Philippines acknowledges the responsibility of all sectors of society to solve the problem. Catholics in the Philippines are opposed to the Ramos' administration's aggressive birth control program. The opposition is due to the government's lack of provision of sufficient information about the side effects of modern contraceptives and the neglect of natural family planning, which is the only morally legitimate form of contraception sanctioned by Roman Catholics.

  3. Biosafety in manned space flight

    2006-01-01

    The main goal of manned exploration is to achieve a prolonged stay in space, for example in an orbital station (such as the International Space Station (ISS)) or in planetary bases on the Moon and/or Mars. It goes without saying that such missions can only be realized when the astronaut's health and well-being is secured. In this respect, the characterization of the microbiological contamination on board spacecraft and orbital stations and the influence of cosmic radiation and microgravity are of paramount importance. Microbial contamination may originate from different sources and includes the initial contamination of space flight materials during manufacturing and assembly, the delivery of supplies to the orbital station, the supplies themselves, secondary contamination during the lifetime of the orbital station, the crew and any other biological material on board e.g. animals, plants, micro-organisms used in scientific experiments. Although most microorganisms do not threaten human health, it has been reported that in a confined environment, such as a space cabin, microorganisms may produce adverse effects on the optimal performance of the space crew and the integrity of the spacecraft or habitat. These effects range from infections, allergies, and toxicities to degradation of air and water supplies. Biodegradation of critical materials may result in system failure and this may jeopardize the crew. The research aims at monitoring the biological airborne and surface contamination during manned space flight. The ISS has been selected as primary test bed for this study. The majority of the investigations are being done by the Russian Institute of Biomedical Problems (IBMP), which is responsible for monitoring the biological contamination in the habitable compartments of the ISS for safety and hygienic reasons. Within the frame of a collaboration between IBMP and the European Space Agency (ESA), SCK-CEN is able to participate in the analyses

  4. Memory of the Present: Empathy and Identity in Young Adult Fiction

    2014-11-01

    Full Text Available Recent studies in cognitive literary criticism have provided scholars of literature with new, stimulating approaches to literary texts and neuroscientists with new insights about human emotions, empathy, and memory through evidence from fiction. What have so far been largely neglected are the implications of cognitive criticism for the study of literature targeting a young audience, whose theory of mind and empathic skills are not yet fully developed. A cognitive approach to children's and young adult literature has to meet several challenges less relevant in general fiction. Firstly, how is a young fictional character's consciousness represented by an author whose cognitive and affective skills are ostensibly superior? Secondly, how do texts instruct their young readers to employ theory of mind in order to assess both the young protagonist's emotions and their understanding of other characters' emotions (higher-order mind-reading? Thirdly, how can fiction support young people's development of their theory of mind? The paper will discuss these issues with a particular focus on memory and identity, expressed textually through tense and narrative perspective. Drawing on work by Lisa Zunshine (2006 and Blackey Vermeule (2010, the predominantly theoretical argument will be illustrated by a contemporary young adult novel, Slated (2012, by Teri Terry.

As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed intently across the swaying grass which rose in wave-like billows across the distant hills. What was that dust - a herd of buffalo, a band of hunters, or were coyotes chasing the antelope again? After watching for a while he started again to chip the flint with a rapid twisting motion of the bone in his right hand. The little chips of flint fell in the grass before him. It is the same hill but the scene has changed. Seated on the same rock, holding the reins of a saddle horse, a man dressed in buckskin took the fur cap off his head and wiped his brow. He was looking intently across a brown and desolate landscape at a cloud of dust on the far horizon. Was it the hostile tribe of Indians? It could be buffalo. Nervously he kicked at the ground with the deerhide moccasin, pushing the flint chips out of the way. He wiped the dust from his long rifle. What a terrible place - no water, practically no grass, everything bare and brown. Now at sunset, slanting across the hills green with springtime, a cowman sits on a big rock, pushes his sombrero back on his head, and looks across the valley at a large but quiet herd of stock, moving slowly as each steer walks from one lush patch of grass to another, nibbling. Suddenly he stood up. Far on the horizon some dark objects were moving. Is it the sheepmen? Could it be the stage coach from Baggs to the Sweetwater Crossing?Same hill - a gray truck was grinding slowly toward the summit. It pulled up near a small fenced enclosure where there were some instruments painted a bright silver color. A man stepped out of the truck and turned to his younger companion, "You've never found an arrowhead? Maybe you have never thought about it correctly. If you want to find where an Indian camped long

  6. The man and the universe

    The universe has always aroused people's curiosity. It fascinates and at the same time scares in its vastness. Encourages us to reflect of the meaning of human life. This begs the questions: whether there is a life beyond Earth? Whether is it possible that the man is alone in such a large space? These questions still remain unanswered, and topics concerning "the cosmos" constantly evoke many emotions. It is especially fascinating for the youngest students. Quite often, preschoolers can flawlessly name the planets according to their order of appearance in relation to the sun. They are happy to take the fun inspired by journeys into space. Teaching through action is extremely important for the development of the child-man* (Piaget, 2006). The thinking originates primarily from the action. Therefore, students should undertake independent research activities, perform experiments and conduct observations and thus raise questions about the world, looking for meanings and solutions. Adults (a teacher, a person with a passion) are to be the support in the search for knowledge, its processing and cleaning. Its role is to ensure a proper development of environment that is conducive to research activity. The answer to these requirements was to create in the oldest technical school in Poland (Railway Technical College, now Technical College No. 7) the astronomical observatory, which can be used by pupils of Warsaw's kindergartens and schools. There are organized activities for children and youth in this school, as well as trainings for teachers. Younger students during such an interdisciplinary courses are, among others, the opportunity to get acquainted with the construction of the telescope, they can build their own rockets and organize their racing or create your own star constellations. Older students as a result of observations and experiments may confirm or refute the hypothesis that the universe is within each of us. The classes are enriched using applications on

    Two frameworks for the study of man are discussed. The Cartesian model views man as a physical object. A dialectic framework, with the emphasis on the self, grew out of nineteenth century romanticism and reflects the theories of Hegel. Both models have had an effect on social psychology and the study of interpersonal communication. (BH)

    Full Text Available Brain iron is tightly regulated by a multitude of proteins to ensure homeostasis. Iron dyshomeostasis has become a molecular signature associated with aging which is accompanied by progressive decline in cognitive processes. A common theme in neurodegenerative diseases where age is the major risk factor, iron dyshomeostasis coincides with neuroinflammation, abnormal protein aggregation, neurodegeneration, and neurobehavioral deficits. There is a great need to determine the mechanisms governing perturbations in iron metabolism, in particular to distinguish between physiological and pathological aging to generate fruitful therapeutic targets for neurodegenerative diseases. The aim of the present review is to focus on the age-related alterations in brain iron metabolism from a cellular and molecular biology perspective, alongside genetics, and neuroimaging aspects in man and rodent models, with respect to normal aging and neurodegeneration. In particular, the relationship between iron dyshomeostasis and neuroinflammation will be evaluated, as well as the effects of systemic iron overload on the brain. Based on the evidence discussed here, we suggest a synergistic use of iron-chelators and anti-inflammatories as putative anti-brain aging therapies to counteract pathological aging in neurodegenerative diseases.

    Transfer to man of transuranic element contamination may occur by the inhalation or ingestion pathways. The measurements of globally dispersed fall-out radioactivity have provided pertinent data on the environmental behaviour of plutonium. Additional data may eventually become available for americium. From the measured and inferred concentrations of fall-out plutonium, the inhalation intake has been determined and the ICRP Task Group lung model used to estimate deposition in the lung and transfer to other body organs. The computed body burden reached a maximum of 4pCi in 1964 and is currently about 2.5pCi. A complete diet sampling has been conducted to determine ingestion intake. Plutonium concentration in food ranged from 0.01pCi/kg in shellfish to undetected (less than 0.0003pCi/kg) in milk. Annual intake in total diet is estimated to have been 1.6pCi in 1972. Low uptake by the gastrointestinal tract makes contribution to organ burdens from ingestion negligible. Long-term pathway considerations include plant uptake from the cumulative deposit in soil and resuspension. Downward movement in soil may limit the significance of these long-term pathway components.

    Nicogossian, A. E.

    1984-01-01

    Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

    Document available in extended abstract form only. At the Mont Terri Underground Rock Laboratory, the gallery Ga08 was excavated in August 2008 to join the end-face of the pre-existing gallery Ga04. The Excavation Damaged Zone (EDZ) induced during the gallery construction was monitored from the instrumented face of Ga04. The EZ-G08 experiments required original acquisition setups, specifically designed to be installed in small boreholes and to ensure long term measurements. Different geophysical methods have been experimented for the EZ-G08 project and specific design of the experiments were required in order to coordinate multiple and simultaneous acquisitions, including acoustic emission (AE) acquisition setup (16 acoustic receivers), manufacturing of a combined electrical (256 electrodes) and acoustic tomography setup (64 receivers) to be introduced in horizontal boreholes with small diameters (56 mm), design of an acoustic source, design and manufacturing of a combined electrical tomography (64 lead electrodes) and self-potential measurements (64 un-polarizable electrodes). Other arrays of electrodes have also been placed at the end-face of Ga04 (715 inox electrodes and an array of 16 un-polarizable electrodes). The self-potential (SP) monitoring took place in the borehole BEZ-G5 equipped in mid- February 2008 with a specific device on which custom-made electrodes were fixed. To avoid polarisation effect and guaranty a satisfactorily signal-to-noise ratio, SP was measured with 64 un-polarizable electrodes, with an offset of 15 cm made of a metallic wire in chemical equilibrium with a surrounding solution containing a salt of the same metal. The electrical contact between the solution and the natural medium is ensured by a porous material. The electrodes were mounted upward on a half-cylinder fixed onto an inflatable pipe and introduced in BEZ-G5. The internal pipe was inflated to ensure a good electrical contact between the electrodes and the borehole wall. The

    The long-term safety of permanent underground repositories relies on a combination of engineered and geological barriers, so that the interactions between the barriers in response to conditions expected in a high-level waste repository need to be identified and fully understood. Co-financed by the European Community, a heater experiment was realized on a pilot plant scale at the underground laboratory in Mont Terri, Switzerland. The experiment was accompanied by an extensive programme of continuous monitoring, experimental investigations on-site as well as in laboratories, and numerical modelling of the coupled thermo-hydro-mechanical processes. Heat-producing waste was simulated by a heater element of 10 cm diameter, held at a constant surface temperature of 100 C. The heater element (length 2 m) operated in a vertical borehole of 7 m depth at 4 to 6 m depth. It was embedded in a geotechnical barrier of pre-compacted bentonite blocks (outer diameter 30 cm) that were irrigated for 35 months before the heating phase (duration 18 months) began. The host rock is a highly consolidated stiff Jurassic clay stone (Opalinus Clay). After the heating phase, the vicinity of the heater element was explored by seismic, hydraulic, and geotechnical tests to investigate if the heating had induced changes in the Opalinus Clay. Additionally, rock mechanic specimens were tested in the laboratory. Finally, the experiment was dismantled to provide laboratory specimens of post - heating buffer and host rock material. The bentonite blocks were thoroughly wetted at the time of the dismantling. The volume increase amounted to 5 to 9% and was thus below the bentonite potential. Geo-electrical measurements showed no decrease of the water content in the vicinity of the heater during the heating phase. Decreasing energy input to the heater element over time suggests hence, that the bentonite dried leading to a decrease of its thermal conductivity. Gas release during the heating period occurred

    Document available in extended abstract form only. In the Underground Research Laboratory (URL) at Mont Terri, a new gallery G08 was planned to be excavated in 2008 following an original process: the excavation process allowed to monitor the Excavation Damaged Zone (EDZ) from geophysical measurements designed and installed at the end of face of the EZ-G04 gallery during the excavation from the other side, i.e. the end face of the EZ-G08 gallery. The objectives of the project concern spatio-temporal changes of the EDZ: among the methodological developments adapted for the EZG08 project to provide complementary information, acoustic experiments have been prepared in horizontal boreholes to perform the continuous acoustic monitoring of the Excavation Damaged Zone (EDZ). The acoustic measurements, performed on acoustic arrays of several receivers, have been recorded during one month, following two main steps: - Active acoustic surveys: a source is introduced in a central borehole (BEZG5) allowing tomography experiments in the far field and in the near field, i.e. close to and far from BEZG5, respectively. - Acoustic emissions: during the excavation process, numerous acoustic emissions can be detected and associated to micro-seismic events due to rapid crack propagation, generated by the rock relaxation, or simply associated to the excavation process. From the tomography measurements, the acoustic wave velocity field can be estimated, with P and S-wave velocities roughly equal to 2500 m/s-3500 m/s, and 1500 m/s, respectively. The acoustic setup does not show variations of P-wave velocity during the campaign, but spatial variations which could be associated to anisotropic elastic properties of the rock with the maximum P-wave velocities close to the bedding plane. An original method based on a multifrequency approach puts in evidence a frequency dependence of the velocity, with a striking phenomena since the wave velocity decreases with increasing frequency.

    Birth and development of the man-made gemstones in the 20th century are outlined. Manufacturing gemstones was initiated by the invention of corundum production, followed by production of rubies and sapphires. In 1950 GE Co. synthesized diamonds, after that, most gemstones were manufactured consequently by progress of technologies of single crystal growing and ceramic manufacturing. In the 21st century, steep growth in demand is not expected but it seems to keep steady growth and the importance and necessity of man-made gemstones may be increased because of global environmental issues. Man-made gemstones seem to have both personality and variety of characteristics. (NEDO)

    The first major man-made environmental problem was the soil acidification, caused primarily by the massive industrial emissions of sulphur dioxide. Then came the problem of ozone depletion, caused by the emissions of man-made halocarbons. More recently, the possibility of man-made climate change has received a lot of attention. These three man-made problems are interconnected in fundamental ways and require for their solution interdisciplinary and international approach. Narrowing of the scientific uncertainties connected with the problems mentioned above can be expected through international `Global Change` programmes such as the World Climate Research Programme (WCRP) and the International Geosphere-Biosphere Programme (IGBP). Periodic assessments of the type produced by the IPCC will clearly be needed. Also in the future such assessments should form the scientific basis for international negotiations and conventions on the climate change issue

    'Nuclear Fuel ' The Thinking Man's Alternative' is the title of the 55th Melchett Lecture given by Neville Chamberlain, Chief Executive of British Nuclear Fuels plc. This article is based on the address, the essence of which is that the case for nuclear power should be based upon an appreciation of the totality and sophistication of man's handling of his energy needs - not on a glib catch-phase or on a simple political dogma or on an economic argument. Arguments in favour of nuclear power were discussed. The conclusion was that nuclear energy is the thinking man's alternative because only thinking man could have and can develop it; secondly, only thinking men should be authorized to exploit and control it; thirdly, a thinking person will appreciate that, properly thought out and controlled, it must be the most important source of future energy for the benefit of mankind.

    1979-01-01

    Numerous studies of the atomic bomb survivors in Hiroshima and Nagasaki have provided no definite evidence of radiation-induced acceleration of aging in man, but several suggestive effects involving tissue markers of the aging process have been demonstrated. The effects have generally been more marked in those persons who were young at the time of exposure. In several studies which were conducted in both cities the age-related radiation effects were greater in Hiroshima than in Nagasaki. (Auth.)

  3. Geomechanical analysis of excavation-induced rock mass behavior of faulted Opalinus clay at the Mont Terri underground rock laboratory (Switzerland)

    Clay rock formations are potential host rocks for deep geological disposal of nuclear waste. However, they exhibit relatively low strength and brittle failure behaviour. Construction of underground openings in clay rocks may lead to the formation of an excavation damage zone (EDZ) in the near-field area of the tunnel. This has to be taken into account during risk assessment for waste-disposal facilities. To investigate the geomechanical processes associated with the rock mass response of faulted Opalinus Clay during tunnelling, a full-scale ‘mine-by’ experiment was carried out at the Mont Terri Underground Rock Laboratory (URL) in Switzerland. In the ‘mine-by’ experiment, fracture network characteristics within the experimental section were characterized prior to and after excavation by integrating structural data from geological mapping of the excavation surfaces and from four pre- and post-excavation boreholes.The displacements and deformations in the surrounding rock mass were measured using geo-technical instrumentation including borehole inclinometers, extensometers and deflectometers, together with high-resolution geodetic displacement measurements and laser scanning measurements on the excavation surfaces. Complementary data was gathered from structural and geophysical characterization of the surrounding rock mass. Geological and geophysical techniques were used to analyse the structural and kinematic relationships between the natural and excavation-induced fracture network surrounding the ‘mine-by’ experiment. Integrating the results from seismic refraction tomography, borehole logging, and tunnel surface mapping revealed that spatial variations in fault frequency along the tunnel axis alter the rock mass deformability and strength. Failure mechanisms, orientation and frequency of excavation-induced fractures are significantly influenced by tectonic faults. On the side walls, extensional fracturing tangential to the tunnel circumference was the

    imaging of pore space at high resolution. The first of them is to use ion beam milling tools able to prepare smooth, damage free cross-sectioned surfaces. Two main ion source are available: (1) a broad ion beam (BIB, up to 3.5 mA) is suitable to produce large polished cross-sections area of few mm 2 , while the focused ion beam (FIB, 1 pA - 45 nA) is better used for fine and precise polished cross-sections area of about few μm 2 . The second alternative is to preserve the in-situ nanostructures of wet clay-stones by using cryogenic techniques in order to stabilize in-situ fluids at temperature of liquid nitrogen. A FIB/BIB-cryo- SEM instrument combines cryo-techniques to preserve wet samples, in-situ sample preparation by ion beam cross-sectioning (BIB or FIB) and observations of the stabilized microstructure at high resolution (SEM). Since the ion beam is directly embedded into the SEM, this instrument offers a unique way to get a direct access of the pore space in 3D by using a 'slice and view' procedure equivalent to nano-serial sectioning. This procedure allows us investigating the natural in-situ pore space as a 3D matrix. This contribution reports on a study of Boom and Opalinus clays from reference sites for research (respectively at Mol site, Belgium and Mont Terri, Switzerland) using cryo-SEM at cryogenic temperature, with ion beam cross-sectioning to prepare smooth, damage free surfaces. Pores commonly have crack-like tips, preferred orientation parallel to bedding and power law size distribution. We define a number of pore types depending on shape and location in the microstructure. 3-D reconstruction by serial cross-sectioning shows 3-D connectivity of the pore space and provide natural pore matrix for simulation of permeability using Lattice Boltzmann method. These findings offer a new insight into the morphology of pores and quantification of porosity down to nano-scale and provide the basis for microstructure-based models of transport in clays

    This is the case of a young man presenting with urethritis despite a negative infectious work-up. Careful history taking elucidated a strong correlation between symptom onset and a recent dose escalation of isotretinoin for treatment of his refractory cystic acne. The urethral symptoms quickly resolved with dose reduction, suggesting urethritis as a rare adverse reaction of isotretinoin.

  8. Some consideration of Japanese standard man value

    1976-01-01

    Numerical values of standard man or reference man is important problem in the field of radiation protection and safety. The standard man values given by ICRP were obtained from European and North American adult data. For that reason, there are some theoretical problems in the application of standard man values to Japanese. The purpose of the present paper is to consider the difference of values between Japanese and standard man. The standard man values are divided into three categories. The first category is the size and weight of the body or organ, the second is the values of elementary composition, and the third is the numerical factors related to metabolic kinetics. It is natural that some values of the second and the third categories have little difference between Japanese and European. On the other hand, there are some differences in the value of the first category, but the differences can calculation in proportional allotment to the body weight. The values concerning the thyroid gland and iodine metabolism are important for radiation protection. It has been foreseen that these values of Japanese are significantly different from standard man. A survey of past reports was carried out with a view to search for normal values of the weight, iodine content, and iodine uptake rate of the thyroid of Japanese. The result of the survey showed that the weight of thyroid are about 19g for adult male and 17g for adult female and that the iodine contents are 12-22mg and iodine uptake rate (fw) is about 0.2.

  10. Happy alone? Sad young men in East Asian gay cinema.

    Science.gov (United States)

    Berry, C

    2000-01-01

    This essay chooses as its texts three films representing contemporary gay male subjects from each of the "three" China's: HK, Taiwan, and the Mainland. Relocating the homoerotic image of the "sad young man," a trope popular from Hollywood rebellion films of the 1950s and 1960s, to contemporary China, I discuss how this masculine icon has been transformed from one of heroic rebellion to one of existential isolation. Indeed, as the politics of both the outmoded Confucian family and fractured Chinese nationhood intersect, what the sad young (gay) man rebels against is a political fluctuation which is no longer fixed; as the young man's opposition is no longer fixed, so too does he become alienated even from his own rebellious cause.

  11. The influence of radiation on fertility in man

    International Nuclear Information System (INIS)

    1980-01-01

    Increasing numbers of young people are now being cured of certain neoplasms by radiotherapy and chemotherapy. Such people will naturally wish to lead a normal life and possibly to have children. Therefore the question of the effect of radiation and cytotoxic drugs on the reproductive capacity of these patients has become important. The purpose of this report is to review the information available on the effect of radiation on fertility in man. Direct information on radiation effects on human fertility is available from reports on therapeutic exposure and deliberate experimental exposure. Although the total number of cases involved is small, a number of general principles emerge. In males, fractionated irradiation of the testes may be more harmful than acute, at least up to total doses of about 600 cGy(rad). Fractionated doses greater than 35 cGy cause aspermia, the time taken for recovery increasing with dose, and after more than 200 cGy aspermia may be permanent. In females, response varies with age as well as dose. For example, 400 cGy may cause a 30% incidence of sterility in young women, but in women aged above 40 years it results in 100% sterility. However, individuals of either sex show a degree of variation in their response to irradiation. (author)

  14. Oedipus king: preparing man for the polis

    José Joaquim Pereira Melo

    2013-09-01

    Full Text Available Having Sophoclean play Oedipus King as a frame of reference, the purpose of this paper is to discuss the educative proposal conceived to the Greek Man as preparation for life in the polis. Although not intentionally, Sophocles pointed out an ideal of Man which, in his perspective, would fulfill Greek societal demands of that time. Such society was divided between myth and rationality and, as a result, Man found Himself in conflict and lacking direction for His life. Given that, Oedipus’ character represented the ideal behavior of that society, and it also made it possible for citizens to reflect and to discuss social, economic and political transformations taking place at that period. Thus Sophocles came up with a hero who was an educational model and a citizen’s as well. Furthermore, such hero differed from that one of the archaic Greek thought.

    Six healthy young subjects (aged 23-32 years), six healthy elderly subjects (over 60 years) and six hospitalized long-stay geriatric subjects over 60 years received single oral doses of acetanilide. Acetanilide clearance was similar in the fit and frail elderly subjects at 26.4 +/- 2.5 and 26.3 +/- 3.6 l/h and significantly lower (p less than 0.05) than in the young subjects at 39.0 +/- 1.9 l/h. Liver volumes, measured by ultrasound, were significantly less in the elderly than in the young subjects, whether expressed in absolute terms or per unit body weight (p less than 0.05). When acetanilide clearance was expressed per unit volume of liver, no change occurred with age or frailty. These results suggest that a reduced liver size may be an important contributor to the reduced elimination of capacity limited drugs in elderly man.

    2007-01-01

    Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

    Sizewell B is the latest nuclear power station to be constructed in the United Kingdom: its Man-Machine Interfaces are therefore, by definition, the state-of-the-art. This paper discusses the principal Man-Machine Interfaces used in the operation of the station, and the systems that implement them. The Man-Machine Interface facilities discussed are: in the Main Control Room, which is used for normal operation and shutdown of the plant: in the Auxiliary Shutdown Room, which allows shutdown of the reactor if evacuation of the main Control Room is necessary: and in the Technical Support Centre, which is used for remote monitoring of the plant. The Man-Machine Interfaces that are described are parts of a station-wide group of interlinked computer systems called the Data Processing and Control System. This system collects data from the plant and displays it to the operators via discrete devices and on graphical computer displays. It also acquires control inputs from the operators via switches, which are then used to provide remote manual control, modulating control and sequence control. The computer system that handles the plant process data and alarm information displays uses a windowing interface with keyboard and trackerball navigation to allow easy retrieval and viewing of information. It is this system that is the main topic of this paper. (author)

  2. From the rights of man to the human rights: Man - nation - humanity

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available The insistence on the fact that human rights and the rights of man (codified in The Universal Declaration of Human Rights and Declaration of the Rights of Man and of the Citizen, respectively are not one and the same, which could be deduced from the notion of man common to both terms, is the key thesis of this text. By developing this motive, I try to determine the following: that the notion of man, by definition inclusive and abstractly non-discriminative term, is in fact established on tacit exclusions in the time of its inception (Enlightenment revolutinary era, and it was only upon these exclusions that the term man could have signified "the free and equal". Although the parallel or simultaneous evolution and implementation of the rights of man and national rights might seem contradictory, I seek to demonstrate that this paradox is only ostensible, arguing that the notion of man is itself limited and exclusionary, and is therefore compatible with the exclusivity which is the conditio sine qua non of nation. The consequences of nationalism - World Wars, primarily - proved that the conception of liberty and equality, based on the conception of fraternity of men (white European males, and of partial democracy pretending to be universal, cannot be maintained any further. Codification of universal human rights represents a reaction to this internal discrepancy inasmuch as it is a reaction to the destructiveness of all kinds of nationalisms. The notion of life, developed in this text, corresponds to the fundamental requirement for the right to life (as the first and the most basic of all human rights, which no longer belongs to "man", but to everyone.

  3. Hydrogeologic characterization and evolution of the 'excavation damaged zone' by statistical analyses of pressure signals: application to galleries excavated at the clay-stone sites of Mont Terri (Ga98) and Tournemire (Ga03)

    2010-01-01

    Document available in extended abstract form only. This paper presents methods of statistical analysis and interpretation of hydrogeological signals in clayey formations, e.g., pore water pressure and atmospheric pressure. The purpose of these analyses is to characterize the hydraulic behaviour of this type of formation in the case of a deep repository of Mid- Level/High-Level and Long-lived radioactive wastes, and to study the evolution of the geologic formation and its EDZ (Excavation Damaged Zone) during the excavation of galleries. We focus on galleries Ga98 and Ga03 in the sites of Mont Terri (Jura, Switzerland) and Tournemire (France, Aveyron), through data collected in the BPP- 1 and PH2 boreholes, respectively. The Mont Terri site, crossing the Aalenian Opalinus clay-stone, is an underground laboratory managed by an international consortium, namely the Mont Terri project (Switzerland). The Tournemire site, crossing the Toarcian clay-stone, is an Underground Research facility managed by IRSN (France). We have analysed pore water and atmospheric pressure signals at these sites, sometimes in correlation with other data. The methods of analysis are based on the theory of stationary random signals (correlation functions, Fourier spectra, transfer functions, envelopes), and on multi-resolution wavelet analysis (adapted to nonstationary and evolutionary signals). These methods are also combined with filtering techniques, and they can be used for single signals as well as pairs of signals (cross-analyses). The objective of this work is to exploit pressure measurements in selected boreholes from the two compacted clay sites, in order to: - evaluate phenomena affecting the measurements (earth tides, barometric pressures..); - estimate hydraulic properties (specific storage..) of the clay-stones prior to excavation works and compare them with those estimated by pulse or slug tests on shorter time scales; - analyze the effects of drift excavation on pore pressures

    Document available in extended abstract form only. Seven different boreholes in the Opalinus Clay formation of the Mont Terri Underground Rock Laboratory (URL Mont Terri) have been investigated by the Clausthal University of Technology (TUC) in cooperation with different partners with time, namely the National Cooperative for the Disposal of Radioactive Waste (NAGRA), the Federal Institute for Geosciences and Natural Resources (BGR) as well as the Swiss Federal Institute of Technology Zurich (ETHZ) and the Swiss Federal Nuclear Safety Inspectorate (ENSI). Aim of the investigations was to gain a large amount of high-quality and significant information on rock mass behaviour that can be used to increase knowledge about and improve understanding of time-dependent load-bearing and deformation behaviour of Opalinus Clay including pore water influences. For this purpose, an axial borehole camera and a three-arm calliper have been used. High-quality information on the load-bearing and deformation behaviour of the investigated boreholes was generated by the measurement and monitoring techniques used in the research project. The recordings reveal great as well as occasionally unexpected differences regarding the load-bearing behaviour as well as differences regarding the hydro-mechanical behaviour of the observed boreholes. While most of the boreholes have proved to be rather stable with only partial failure of the borehole wall in some areas, a complete borehole wall collapse occurred in two of the observed boreholes. The differences regarding the borehole wall stability and also the differences between the appearances of the occurring failure mechanisms are very likely due to the different orientation, the different locations within the URL Mont Terri, and the different facies the boreholes are located in. Figure 1 shows the time-dependent development of a borehole wall instability in one of the observed boreholes in a borehole section where an increase of moisture could

Revisiting the case, and the responses the mystery of his person have elicited, enables a special historical insight into Australia’s postwar society, and the ways in which the past is continually reshaped by the subjectivities of the present. Further, an unsolved case such as this provides for a unique kind of historical project. The limitations of a history without a coherent centre are myriad, yet so are the possibilities. In this article, I explore the possibilities of an ‘unsolved history’, a history of dead ends, and argue that it is the very unknowable-ness of the Somerton Man that allows for a perception of history as multi-dimensional and complex.

    The field of man-machine systems is introduced with its subareas and a short outline of its history of 45 years. Three current lines of development in university and industrial research are emphasized. Today, the human problem solving activities are experimentally investigated and analytically described more vigorously than the control activities. Further, improved information presentations and decision support are made possible through new technologies of computer graphics and expert systems. At last, work on a general design methodology for man-machine systems is in progress. The aim is to better support human operators of dynamic technological systems as well as designers of graphics for visual display units and of dialogue styles. Thereby, safety and availability of the complete system can be increased. (orig.) [de

    2013-01-01

    From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

  11. Man-midwifery history: 1730-1930.

    Science.gov (United States)

    Shelton, D C

    2012-11-01

    This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.

    Eliminating middlemen from security protocols helps less than one would think. EMV electronic payments, for example, can be made fairer by adding an electronic attorney - a middleman which mediates access to a customer’s card. We compare middlemen in crypto protocols and APIs with those in the real world, and show that a man-in-the-middle defence is helpful in many circumstances. We suggest that the middleman has been unfairly demonised.

Attempts at eliminating such rodents by increasing predation (including traps, microbiological agents, toxicants) have been relatively unsuccessful. Management by environmental manipulation must be basic. This then can be supplemented with predation at critical points where public health, use practices, or imperfections in the system demand. Society mores, practices, and economic considerations also have significant impact on the management system

  6. The effects of ionizing radiation on man

    International Nuclear Information System (INIS)

    Watson, G.M.

    1975-08-01

    This paper describes the major effects of ionizing radiation on man and the relationship between such effects and radiation dose, with the conclusion that standards of radiological safety must be based on the carcinogenetic and mutagenic properties of ionizing radiation. Man is exposed to radiation from natural sources and from man-made sources. Exposure from the latter should be regulated but, since there is little observational or experimental evidence for predicting the effects of the very small doses likely to be required for adequate standards of safety, it is necessary to infer them from what is seen at high doses. Because the formal relationship between dose and effect is not fully understood, simplifying assumptions are necessary to estimate the effects of low doses. Two such assumptions are conventionally used; that there is a linear relationship between dose and effect at all levels of dose, and that the rate at which a dose of radiation is given does not alter the magnitude of the effect. These assumptions are thought to be conservative, that is they will not lead to an underestimation of the effects of small radiation doses although they may give an over-estimate. (author)

    In any complex system, the interesting problems occur at the interface of dissimilar subsystems. Control of the Mirror Fusion Test Facility (MFTF) begins with the US Congress, which controls the dollars, which control the people, who control the nine top-level minicomputers, which control the 65 microprocessors, which control the hardware that controls the physics experiment. There are many interesting boundaries across which control must pass, and the one that this paper addresses is the man-machine one. For the MFTF, the man-machine interface consists of a system of seven control consoles, each allowing one operator to communicate with one minicomputer. These consoles are arranged in a hierarchical manner, and both hardware and software were designed in a top-down fashion. This paper describes the requirements and the design of the console system as a whole, as well as the design and operation of the hardware and software of each console, and examines the possible form of a future man-machine interface

  8. Pathways of evolution for man and machine

    1983-01-01

    A simplified model of the future is introduced in order to examine the relations between man, machine, and extraterrestrial intelligence. The observed lack of extraterrestrials on earth is used as a boundary condition for the model. Two exobiological conclusions are obtained: (1) advanced extraterrestrials exist but are difficult to observe or to distinguish from natural phenomena, (2) lower level, man-like extraterrestrials, which are potentially observable, are rare in the Universe because they are rapidly replaced in the evolutinary sequence by the intelligent machines which they create. The decline of man is inferred and may take place as soon as 100 years from now or as long as 100,000 years from the present time. Thus, we are a short-lived species, having a life expectancy of only a million years. A note is appended on the rationale and methods of the search for extraterrestrial intelligence in light of the above calculations. The Tau Ceti and Epsilon Eridani systems present favourable opportunities for a radio-search experiment in 1987 and 1988, respectively.

    Full Text Available Objective. Ewing’s sarcoma of the kidney is rare and is usually found in young adults. We present here a single case study of Ewing's sarcoma found in an elderly man. Material and methods. A 73-year-old man underwent routine surgery for hydrocoele of the testis. He developed urinary obstruction symptoms, and radiological examinations revealed a tumour in the right kidney. Results. Microscopical, immunohistochemical, and molecular pathological analysis of the tumour was consistent with Ewing's sarcoma. FISH showed rearrangement of chromosomes 22q12 (EWSR1. The patient subsequently underwent nephrectomy followed by 6 adjuvant chemotherapy cycles. Follow-up after 7 months shows no recurrence. Conclusion. This case report presents not only the rare finding of Ewing's sarcoma in the kidney, but also the occurrence of this tumour entity in an elderly patient. Treatment options for the different types of renal tumours are vastly different and the need for a correct diagnosis is, therefore, vital.

    2006-12-01

    Full Text Available Abstract Background Phylogenetic analysis of large, multiple-gene datasets, assembled from public sequence databases, is rapidly becoming a popular way to approach difficult phylogenetic problems. Supermatrices (concatenated multiple sequence alignments of multiple genes can yield more phylogenetic signal than individual genes. However, manually assembling such datasets for a large taxonomic group is time-consuming and error-prone. Additionally, sequence curation, alignment and assessment of the results of phylogenetic analysis are made particularly difficult by the potential for a given gene in a given species to be unrepresented, or to be represented by multiple or partial sequences. We have developed a software package, TaxMan, that largely automates the processes of sequence acquisition, consensus building, alignment and taxon selection to facilitate this type of phylogenetic study. Results TaxMan uses freely available tools to allow rapid assembly, storage and analysis of large, aligned DNA and protein sequence datasets for user-defined sets of species and genes. The user provides GenBank format files and a list of gene names and synonyms for the loci to analyse. Sequences are extracted from the GenBank files on the basis of annotation and sequence similarity. Consensus sequences are built automatically. Alignment is carried out (where possible, at the protein level and aligned sequences are stored in a database. TaxMan can automatically determine the best subset of taxa to examine phylogeny at a given taxonomic level. By using the stored aligned sequences, large concatenated multiple sequence alignments can be generated rapidly for a subset and output in analysis-ready file formats. Trees resulting from phylogenetic analysis can be stored and compared with a reference taxonomy. Conclusion TaxMan allows rapid automated assembly of a multigene datasets of aligned sequences for large taxonomic groups. By extracting sequences on the basis of

    Full Text Available This article draws on research with a gay Hmong young man to illustrate the ways in which coming out discourses fail to take into account the central importance of family and kinship forgay Hmong Americans. It draws on the narratives of a gay Hmong man that emphasizes the importance of family reputation and family bonds to offer an alternative discourse to coming out narratives. It advances understandings of gay identity and experiences by explicating the ways in which family and community are important for a gay Hmong American man. This research significantly contributes to the dearth of research on Asian American LGBT experiences ingeneral and those of LGBT Hmong Americans in particular.

    Li, Zhijie

    2016-07-01

    Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

    A conjunction class split/sprint manned Mars exploration mission was studied to evaluate tradeoffs in performance characteristics of nuclear thermal rockets. A Particle Bed Reactor-based nuclear thermal rocket was found to offer a 38% to 52% total mass savings compared with a NERVA-based nuclear thermal rocket for this mission. This advantage is primarily due to the higher thrust-to-weight ratio of the Particle Bed Reactor nuclear rocket. The mission is enabled by nuclear thermal rockets. It cannot be performed practically using chemical propulsion

    Nuclear power is accepted as a reality in this description of the nature of radioactivity, its presence in the operation of a nuclear reactor, how and why some of the radioactivity is introduced into the environment in a controlled manner, and how these processes should be judged. The didactic approach makes the account an informative one rather than argumentative. The basic properties of radioactivity and its interaction with matter are described in the first chapter. Subsequent chapters deal with the radiation background, radiation and man, nuclear reactors and their fuel cycles, radioactive wastes and the public, environmental behavior and effects, and the acceptability of future discharges. 10 references, 41 figures, 57 tables.

    1. The effect of calcitonin, a large amount of calcium given orally, pentagastrin and glucagon on plasma 47Ca radioactivity curves in subjects pretreated with 47Ca was examined. 2. A sudden increase of plasma radioactivity after intravenous administration of calcitonin and pentagastrin and after the oral calcium load was observed in normal subjects; the intravenous infusion of glucagon was less effective. 3. Two thyroparathyroidectomized patients who responded to the calcitonin infusion did not respond to the oral calcium load. 4. These data may be considered to offer indirect evidence of endogenous calcitonin secretion in man.

    A method has been established for determining the fractional absorption of uranium directly in man. Measurements are made of the urinary excretion rates of uranium for individuals whose drinking water has a high 234 U to 238 U activity ratio and is the primary source of 234 U in their diets. For two individuals, the values obtained for the fractional absorption of 234 U were 0.004 and 0.006. The values obtained for the fractional absorption of 238 U, using a literature value for the 238 U intake from food, were 0.008 and 0.015. The present ICRP value is 0.20. 7 references, 1 table

    Benton, A.R. Jr.; Snell, W.W.

    1979-01-01

    The paper examines the monitoring of man's impact in the coastal zone. Color infrared photography shows destroyed or degraded wetlands or beaches, and makes possible relevant linear or aerial measurements with aerial photography. It can also categorize the environmental impacts which have accrued as the result of completion of water development projects. Aerial photography of the Texas coastal zone illustrates the nature and degree of damage likely to occur as a result of construction or maintenance projects. It is concluded that the method of assigning realistic values to unit areas of wetlands and beaches will make it feasible to incorporate the cost of estuarine damages into the cost estimates of water development schemes

    This work reports the development of a Man Machine Interface based on speech recognition. The system must recognize spoken commands, and execute the desired tasks, without manual interventions of operators. The range of applications goes from the execution of commands in an industrial plant's control room, to navigation and interaction in virtual environments. Results are reported for isolated word recognition, the isolated words corresponding to the spoken commands. For the pre-processing stage, relevant parameters are extracted from the speech signals, using the cepstral analysis technique, that are used for isolated word recognition, and corresponds to the inputs of an artificial neural network, that performs recognition tasks.

    2010-05-01

    A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining may account for incipient activations in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, though damages of workings themselves do not happen, but intensive shaking on surface calls for intent study of so dangerous phenomena. In 2009 replicates of the experiment on research of seismic activations in area of before investigated lavas have been conducted

    Analysis methods based on theories for action regulation provide essential information about the origin of operators' failures. Preventive measures based on this are adaptive training and pinpointed support by computer-aided information and calculation systems. Such systems do not meet their purpose by the fact that they employ high-performance equipment and there are some displays in the control room but only if they are substantially oriented towards man - subordinate to his thought and action structures. Some proposals are given with regard to those problems. (orig.) [de

    Ewing's sarcoma usually arises in the bones of children and adolescents. We herein report a 74-year-old man with Ewing's sarcoma in the adrenal gland. The diagnosis was confirmed by a genetic test, pathological studies, and several imaging studies. He already had multiple liver metastases when he was transferred to our hospital and died on the 37th day. The diagnosis was further confirmed by autopsy studies. Adrenal Ewing's sarcoma is very rare, and our patient was older than other reported cases. Ewing's sarcoma should be considered even in elderly patients with adrenal tumors.

    Listeriosis is a food-borne illness leading to bacteriemia or central nervous system infection especially in pregnant women or high-risk patients. It is rarely a localized infection. Breast contamination has rarely been reported in lactating women. We report a breast abscess in man. A 80 year old man, hypertensive and arrhythmic, was explored for weakness and dehydration. Type 2 diabetes and chronic lymphocytic leukemia were diagnosed. Clinical examination disclosed a breast abcess related to L monocytogenes infection. Histopathological study also revealed a breast subcutaneous infiltration by chronic lymphocytic leukemia. Listeriosis sometimes uncover an unknown immunosuppression, especially in the elderly. Breast is a non-sterile tissue containing a stable microbiome partly from digestive origin. It can thereby be contaminated by Listeria. The specific cutaneous infiltrate of chronic lymphocytic leukemia can create the conditions for a local infection. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

    The Great East Japan Earthquake that occurred on 11 March 2011 generated a series of large tsunami waves that caused serious damage to the Fukushima Dai-ichi Nuclear Power Station, following which a large amount of radioactive material was discharged from the nuclear power plant into the environment. Airborne radiation measurements using a manned helicopter were applied to measure the radiation distribution immediately after accident as technique to quickly measure the radiation distribution over a wide area. In Japan, this technique was researched and developed in the 1980s. However, this technique and system were not applied immediately after the accident because standardization of analysis was not established and the Japanese system became deteriorated. This technique is important for post-accident studies at a nuclear facility. We summarized the methods of the airborne radiation measurement using a manned helicopter. In addition, measurement results of the dose rate distribution at the Fukushima Dai-ichi Nuclear Power Station are given in this paper. (author)

    Present methods for quantifying radiation exposure rely on a standardized reference man (75 kg) with defined average anatomical and physiological data. But individual person actually exposed differs from this idealized standard man. Therefore the focus of investigations at the Institute for Radiation Research (Institut fuer Strahlenforschung, ISF) which was founded at Karlsruhe Institute of Technology (Karlsruher Institut fuer Technologie, KIT) in 2009 is based on the vision to place the exposed individual with its anatomical and physiological particularities, under consideration of age, gender, body height, body shape and environment, in the centre of an individual-related quantification of the external and internal radiation exposure. Research work at the ISF is aiming at quantifying radiation exposure by improved determination of doses essentially caused by external radiation fields and the intake of radionuclides into the body. The three main topics of the institute are - external dosimetry (e.g. using a (voxel) model of the hand to simulate skin dose distribution); - internal dosimetry (e.g. body size related efficiency calibration of in-vivo counting equipment); - numerical methods/modeling (e.g. development of a mathematical/voxel-hybrid model of the human body).

    1997-01-01

    The ever-changing climate shapes the Arctic landscape, influences life conditions for plants and animals and alters the availability of the living resources that play such and important part in the economy of Arctic peoples. It is essential that we try to understand the nature of climatic change and its effects on man and his environment. Only this way can we hope to be able to predict future changes that may have great consequences for the well-being of northern residents. In recent years many research projects have been addressing the subject and important advances have been made. At the same time it has become increasingly evident that the complexity of the whole issue calls for an integration of scientific approaches and for interdisciplinary collaboration. The seminar 'Climate and Man in the Arctic' provided an opportunity both to highlight important areas of climate related research and to discuss more general aspects of arctic research. Eight papers presented at the seminar are published in this volume. (au) 22 refs

  13. Adaptive myelination from fish to man.

    Science.gov (United States)

    Baraban, Marion; Mensch, Sigrid; Lyons, David A

    2016-06-15

    Myelinated axons with nodes of Ranvier are an evolutionary elaboration common to essentially all jawed vertebrates. Myelin made by Schwann cells in our peripheral nervous system and oligodendrocytes in our central nervous system has been long known to facilitate rapid energy efficient nerve impulse propagation. However, it is now also clear, particularly in the central nervous system, that myelin is not a simple static insulator but that it is dynamically regulated throughout development and life. New myelin sheaths can be made by newly differentiating oligodendrocytes, and mature myelin sheaths can be stimulated to grow again in the adult. Furthermore, numerous studies in models from fish to man indicate that neuronal activity can affect distinct stages of oligodendrocyte development and the process of myelination itself. This begs questions as to how these effects of activity are mediated at a cellular and molecular level and whether activity-driven adaptive myelination is a feature common to all myelinated axons, or indeed all oligodendrocytes, or is specific to cells or circuits with particular functions. Here we review the recent literature on this topic, elaborate on the key outstanding questions in the field, and look forward to future studies that incorporate investigations in systems from fish to man that will provide further insight into this fundamental aspect of nervous system plasticity.

  14. Abstraction of man-made shapes

    Man-made objects are ubiquitous in the real world and in virtual environments. While such objects can be very detailed, capturing every small feature, they are often identified and characterized by a small set of defining curves. Compact, abstracted shape descriptions based on such curves are often visually more appealing than the original models, which can appear to be visually cluttered. We introduce a novel algorithm for abstracting three-dimensional geometric models using characteristic curves or contours as building blocks for the abstraction. Our method robustly handles models with poor connectivity, including the extreme cases of polygon soups, common in models of man-made objects taken from online repositories. In our algorithm, we use a two-step procedure that first approximates the input model using a manifold, closed envelope surface and then extracts from it a hierarchical abstraction curve network along with suitable normal information. The constructed curve networks form a compact, yet powerful, representation for the input shapes, retaining their key shape characteristics while discarding minor details and irregularities. © 2009 ACM.

    Online Mendelian Inheritance In Man (OMIM) is a public database of bibliographic information about human genes and genetic disorders. Begun by Dr. Victor McKusick as the authoritative reference Mendelian Inheritance in Man, it is now distributed electronically by the National Center for Biotechnology Information (NCBI). Material in OMIM is derived from the biomedical literature and is written by Dr. McKusick and his colleagues at Johns Hopkins University and elsewhere. Each OMIM entry has a full text summary of a genetic phenotype and/or gene and has copious links to other genetic resources such as DNA and protein sequence, PubMed references, mutation databases, approved gene nomenclature, and more. In addition, NCBI's neighboring feature allows users to identify related articles from PubMed selected on the basis of key words in the OMIM entry. Through its many features, OMIM is increasingly becoming a major gateway for clinicians, students, and basic researchers to the ever-growing literature and resources of human genetics.

    2018-04-01

    Terrorism, whether it is group-related or performed as lone actor terrorism, is a predominantly male phenomenon. Generally and throughout history, young males have been the main protagonists of criminal and political violence.This article aims to contribute, from different perspecives, to the question of what makes young men violent. These include neurobiological aspects, such as sex differences in the brain that predispose males to physical aggression and violence; gender role aspects, with regard to aggression and violence being basic components for demonstrating and reconstructing masculinity; demographic aspects of male youth bulges as potential breeding grounds for terrorism; aspects of group dynamics and identity fusion in the process of radicalization; and psychosocial characteristics of lone actor terrorists, which differ from group-related terrorists.It is concluded that in addition to ideological, political, economic, regional, demographic, or psychosocial causes, experiences of threatened masculinity may be an underlying factor and driving force for terrorism.

    2018-04-01

    Red man syndrome (RMS) is a well-known hypersensitivity reaction caused by intravenous administration of vancomycin, with symptoms ranging from flushing, erythematous rash, pruritus, mild to profound hypotension, and even cardiac arrest. RMS has not previously been described from local application of vancomycin powder in a surgical wound, a technique increasingly utilized for infection prophylaxis in many surgical disciplines including neurosurgery. We describe the first reported case of RMS as a result of local intra-wound application of vancomycin powder for infection prophylaxis. A 73-year-old male with a history of Parkinson's disease underwent 2-stage deep brain stimulation implantation surgeries. Vancomycin powder was applied locally in the surgical wounds for infection prophylaxis during both of the surgeries. The patient developed a well-demarcated, geometric erythematous pruritic rash following the second surgery that was clinically diagnosed as RMS and resolved without sequelae.

The books are Sur l'homme et le développement de ses facultés and Du systeme social et des lois qui le régissent. Both reveal that Quetelet's ideas are permeated by explanatory strategies drawn from physics and astronomy, and also by discursive strategies drawn from theology and religion. The stability of the mean as opposed to the dispersion of individual characteristics and events provided the basis for the use of statistics in social sciences and medicine.

    This book is an attempt to describe briefly the nature of radioactivity, how it arises in the day-to-day operation of a nuclear reactor, how and why a small fraction is introduced into the environment in a controlled manner, and on what basis such judgements are made. It is an account of current practice, and an attempt to be didactic rather than polemic. As a general subject area it is one which involves many disciplines and therein lies its particular scientific interest, especially for the ecologist. It is also a subject area of continuing research and one of increasing public awareness. The chapters are entitled: radioisotopes - their characterization and interaction with matter; the radiation background; radiation and man; nuclear reactors and their fuel cycles; radioactive wastes and the public; environmental behaviour and effects; the future.

    Full Text Available “The Preface” was finished after the work on “Reflections of a unpolitical Man” and explains the reasons behind its creation. Thomas Mann decided that armed conflict between Germany and the West was the result of different perspectives. Democracy damages the world order and German values. The greatest advocate of democracy among Germans is the civilization’s man of letters. Mann undermines the value of his art and gives reasons for the disagreements with this revolutio-nary knowledge, which he calls “The new Pathos”. He develops the theory of the greatness of Germans as a nonpolitical nationality, recognizing Martin Luther as a reflection of this theory. He mentions the great minds of the 18th and 19th centuries to emphasize the most crucial differen- ces, seeing in himself a child of the 19th century. In conclusion, Mann claims that his opposition to democracy hastens its victory.

    Fixed cutaneous sporotrichosis is a differential diagnosis that can be considered in diabetic patients who present with a poorly healing ulcer. Although its prevalence is low, it can occur in patients with immunocompromised status. Here we report a case of a 70-year-old man with diabetes mellitus who presented with a 1-month history of an unhealed ulcer over the tip of his left middle finger. He experienced a cat bite over his left middle finger 1 month prior to the appearance of the lesion. A skin biopsy revealed the presence of Sporothrix schenckii . Oral itraconazole 200 mg twice daily was started empirically and the patient showed marked improvement in the skin lesion after 2 months of therapy.

    1981-10-01

    This paper provides an elementary discussion of the problems of verification and validation in the context of the empirical evaluation of designs for man-machine systems. After a definition of the basic terms, a breakdown of the major parts of the process of evaluation is given, with the purpose of indicating where problems may occur. This is followed by a discussion of verification and validation, as two distinct concepts. Finally, some of the practical problems of ascertaining validity are discussed. The general conclusion is that rather than rely blindly on a well-established procedure or rule, one should pay attention to the meaningfulness of the aspects which are selected for observation, and the degree of systematism of the methods of observation and analysis. A qualitative approach is thus seen as complementary to a quantitative approach, rather than antithetical to it. (author)

    The Calysto: Risk Management for Commercial Manned Spaceflight study analyzes risk management in large enterprises and how to effectively communicate risks across organizations. The Calysto Risk Management tool developed by NASA's Kennedy Space Center's SharePoint team is used and referenced throughout the study. Calysto is a web-base tool built on Microsoft's SharePoint platform. The risk management process at NASA is examined and incorporated in the study. Using risk management standards from industry and specific organizations at the Kennedy Space Center, three methods of communicating and elevating risk are examined. Each method describes details of the effectiveness and plausibility of using the method in the Calysto Risk Management Tool. At the end of the study suggestions are made for future renditions of Calysto.

  11. Biomedical support of man in space

    Science.gov (United States)

    Pendergast, D. R.; Olszowka, A. J.; Rokitka, M. A.; Farhi, L. E.

    In its broadest sense, biomedical support of man in space must not be limited to assisting spacecraft crew during the mission; such support should also ensure that flight personnel be able to perform properly during landing and after leaving the craft. Man has developed mechanisms that allow him to cope with specific stresses in his normal habitat; there is indisputable evidence that, in some cases, the space environment, by relieving these stresses, has also allowed the adaptive mechanisms to lapse, causing serious problems after re-entry. Inflight biomedical support must therefore include means to simulate some of the normal stresses of the Earth environment. In the area of cardiovascular performance, we have come to rely heavily on complex feedback mechanisms to cope with two stresses, often combined: postural changes, which alter the body axis along which gravitational acceleration acts, and physical exercise, which increases the total load on the system. Unless the appropriate responses are reinforced continuously during flight, crew members may be incapacitated upon return. The first step in the support process must be a study of the way in which changes in g, even of short duration, affect these responses. In particular we should learn more about effects of g on the "on" and "off" dynamics, using a variety of approaches: increased acceleration on one hand at recumbency, immersion, lower body positive pressure, and other means of simulating some of the effects of low g, on the other. Once we understand this, we will have to determine the minimal exposure dose required to maintain the response mechanisms. Finally, we shall have to design stresses that simulate Earth environment and can be imposed in the space vehicle. Some of the information is already at hand; we know that several aspects of the response to exercise are affected by posture.

  12. Measurement of total body radioactivity in man

    Naversten, Y.

    1982-01-01

    Techniques for the determination of whole-body radioactivity in man using uncollimated NaI(Tl) detectors have been studied. Geometrical effects and photon attenuation effects due to the different shapes of humans as well as due to varying in-vivo radioactivity distributions have been evaluated particularly for scanning-bed geometries and the chair geometry. Theoretically it is shown that the attenuation effects are generally dominating, for full-energy-peak pulse-range methods. For the application in radiation protection a cheap and simple chair-geometry unit has been constructed and used at various places distantly from the home-laboratory, for studies of body activity of Cs-137 in northern Sweden. High body activities were found particularly in reindeer-breeding Lapps. The elimination rate of Cs-137 in man was studied in the stationary whole-body counter in Lund as well as with the field-system. For the study of the performances at low and high photon energies clinical applications of methods for gastro-intestinal absorption of vitamin B12 (Co-57; 122 keV) and total body potassium determination (K-40; 1.46 MeV, K-42; 1.52 MeV) have been evaluated. Theoretical and experimental results as well as experiences of applications in radiation protection and medicine show that the scanning-bed geometry effectively evens out redistributional effects. For optimum results, however, scatter-energy pulse-ranges rather than full-energy-peak ranges should be used. (Auth.)

  13. Two-Man Bobsled Push Start Analysis

    Full Text Available The importance of push start times on bobsled performance was evidenced by some studies, but at this moment there is no article to the authors’ knowledge that describes the bobsled push start. Thus, the objectives of this study were to describe the two-man bobsled push start, analyze the differences between teams, and estimate the most important variable analyzed. We hypothesized that the pilot and brakeman athletes’ movement patterns during a bobsled pushing start can be described. The images used in this study were obtained during the men’s two-man XIV World Championship of Bobsled (2004. Fifteen best teams participating in the championship were recorded, and four start runs for each team were analyzed. The videos were captured by two digital video cameras. The pilot athletes were analyzed during the moment that they touched the lateral push bar of the sled, and the brakemen were analyzed during the first take-off and first landing. The teams were pooled in three groups of five teams using the final ranking of pushing time. We concluded that there was a distinct pattern movement for pilots and brakemen. The initial position of the majority of the pilots was localized slightly behind the bar. After touching the lateral bar, the pilots remained in a semi-squat position, pushing the sled forward in a pattern of marching movement. All brakemen used the board attached to the track as a support for both feet at the start. The brakeman gave the greatest contribution to break the inertia of the sled. There was no significant difference of movement between the three groups analyzed for the pilot and the brakeman.

    MAN Nutzfahrzeuge AG (Munich, Federal Republic of Germany) always is eager to offer products for the respective markets whereby the products are interesting for the customer under economic criteria. Additionally, the products shall not lack in the travelling comfort under consideration of the legal emission borders. Thus, a AdBlue {sup registered} free technology for all MAN series was already offered before the legal introduction of EURO IV. This technology is based on an internal-motor solution with external, cooled AGR and a PM-Cat {sup registered} -filter. This solution is esteemed highly by our customers because apart from the well-known advantages in relation to a SCR technology there were no losses with the operating cost. With EURO V which is inserted in some countries MAN Nutzfahrzeuge AG returns to a long-term experience with SCR technology. The motivation for the development of a AdBlue {sup registered} free solution was the positive feedback of our customers on the basis of MAN EURO IV AGR/PM Cat technology. With the developed EURO V AGR solution, other EURO IV solutions in line with market conditions for the 'Emerging markets' can be derived with which a technology without exhaust post-treatment can be offered worldwide for our customers. This technology presents the basis for a platform concept EURO IV/V and EURO VI. In this concept, EURO IV can be presented without subsequent treatment of exhaust gases, EURO V in connection with an Oxicat and EURO VI with a SCRT system. Here, the vehicle/engine concept presents the most important components for the individual series in particular. By means of these components, the goal EURO V was achieved internal-motor without losses of operating cost and life span in relation to SCR technologies.

  16. Operational Philosophy Concerning Manned Spacecraft Cabin Leaks

    Science.gov (United States)

    DeSimpelaere, Edward

    2011-01-01

    The last thirty years have seen the Space Shuttle as the prime United States spacecraft for manned spaceflight missions. Many lessons have been learned about spacecraft design and operation throughout these years. Over the next few decades, a large increase of manned spaceflight in the commercial sector is expected. This will result in the exposure of commercial crews and passengers to many of the same risks crews of the Space Shuttle have encountered. One of the more dire situations that can be encountered is the loss of pressure in the habitable volume of the spacecraft during on orbit operations. This is referred to as a cabin leak. This paper seeks to establish a general cabin leak response philosophy with the intent of educating future spacecraft designers and operators. After establishing a relative definition for a cabin leak, the paper covers general descriptions of detection equipment, detection methods, and general operational methods for management of a cabin leak. Subsequently, all these items are addressed from the perspective of the Space Shuttle Program, as this will be of the most value to future spacecraft due to similar operating profiles. Emphasis here is placed upon why and how these methods and philosophies have evolved to meet the Space Shuttle s needs. This includes the core ideas of: considerations of maintaining higher cabin pressures vs. lower cabin pressures, the pros and cons of a system designed to feed the leak with gas from pressurized tanks vs. using pressure suits to protect against lower cabin pressures, timeline and consumables constraints, re-entry considerations with leaks of unknown origin, and the impact the International Space Station (ISS) has had to the standard Space Shuttle cabin leak response philosophy. This last item in itself includes: procedural management differences, hardware considerations, additional capabilities due to the presence of the ISS and its resource, and ISS docking/undocking considerations with a

  17. Manned in Situ Confirmation of Lunar Ice

    Gerené, S. P. B.; Hummeling, R. W. J.; Ockels, W. J.

    A study is performed to investigate the feasibility of a manned expedition to the Moon using the European Ariane-5 launcher. The primary objective of this lunar mission is to confirm the presence of water at the South-Pole craters. It is believed that these permanently shadowed craters contain water in the form of ice. Secondary objective is to perform lunar surface science and making a first step towards a lunar outpost. Early results show that a minimum of two Ariane-5 launches is required. In this `two Ariane' scenario the first launch will bring a Lunar Landing Vehicle (LLV) into low lunar orbit. The second will launch two astronauts in a Crew Transfer Vehicle into a rendez- vous trajectory with the LLV. Arrived at the Moon, the astronauts will enter the LLV, undock from the CTV and land at the designated site located near the rim of the South-Pole Shackleton crater. The transfer strategy for both spacecraft will be the so-called direct transfer, taking about four days. At arrival the LLV will start mapping the landing site at a ground resolution of one meter. As a consequence of the polar orbit, the CTV has to arrive fourteen days later and surface operations can take about twelve days, accumulating in a total mission-duration of 36 days. 32 days for the CTV and 22 days for the LLV. In case a `two Ariane' flight does not posses sufficient capabilities also a `three Ariane' scenario is developed, in which the LLV is split-up into two stages and launched separately. These two will dock at the Moon forming a descent stage and an ascent stage. The third launch will be a CTV. During surface operations, astronauts will set up a solar power unit, install the sample retrieval system and carry out surface science. Samples of the crater floor will be retrieved by means of a probe or robot guided along a cable suspended over the crater rim. Also, this paper shows the way in which European astronauts can be brought to the Moon for other future missions, like the

  13. The Walk-Man Robot Software Architecture

    Directory of Open Access Journals (Sweden)

    Mirko Ferrati

    2016-05-01

    Full Text Available A software and control architecture for a humanoid robot is a complex and large project, which involves a team of developers/researchers to be coordinated and requires many hard design choices. If such project has to be done in a very limited time, i.e., less than 1 year, more constraints are added and concepts, such as modular design, code reusability, and API definition, need to be used as much as possible. In this work, we describe the software architecture developed for Walk-Man, a robot participant at the Darpa Robotics Challenge. The challenge required the robot to execute many different tasks, such as walking, driving a car, and manipulating objects. These tasks need to be solved by robotics specialists in their corresponding research field, such as humanoid walking, motion planning, or object manipulation. The proposed architecture was developed in 10 months, provided boilerplate code for most of the functionalities required to control a humanoid robot and allowed robotics researchers to produce their control modules for DRC tasks in a short time. Additional capabilities of the architecture include firmware and hardware management, mixing of different middlewares, unreliable network management, and operator control station GUI. All the source code related to the architecture and some control modules have been released as open source projects.

  14. Environmental pathways of radioactivity to man

    International Nuclear Information System (INIS)

    Johns, T.F.

    1979-12-01

    The report reviews and discusses the environmental pathways by which radioactive materials can lead to the irradiation of man, in a way that should be understood by non-specialists who have neither the time nor the knowledge to study all of the relevant literature on this subject. The role of these environmental pathways in the general structure of radiological protection is considered, and the various mechanisms which lead to the dispersion or re-concentration of radioactive materials are discussed at some length. Particular groups of radionuclides from the nuclear power industry are considered in some detail. Similarly the question of the corresponding pathways from naturally-occurring radioactive materials is covered. The doses to animals and plants resulting from the nuclear industry are examined, and it is concluded that there is no reason to expect that these doses will lead to significant harm. Finally a summary is presented, and it is noted that it has been possible to obtain a very extensive knowledge of the behaviour of radionuclides in the environment only because of the extreme sensitivity of the techniques available for their detection, identification and assay. As a result a fund of knowledge has been built up about the behaviour of radioactive materials in the environment which is far more extensive than our knowledge of the behaviour of many highly toxic chemicals which are also discharged into the environment.

  15. Radiation-induced cancers in man

    International Nuclear Information System (INIS)

    Hirose, Fumio

    1978-01-01

    Radiation-induced cancers in man were divided into three groups, a group in which cancers occurred after atomic bomb exposure, a group in which cancers occurred in radiologists and other medical specialists, and a group in which cancers occurred after exposure to diagnostic radiation, and they were summarized. In atomic bomb survivors leukemia, thyroid cancer, salivary gland cancer, lung cancer, and breast cancer occurred so frequently. In addition to them, mortality ratios by malignant lymphoma, stomach cancer, esophageal cancer, and by cancer of urinary tract were increased. The incidence of leukemia was decreased in those who treated radiation owing to the development of the protection of occupational exposure, and the incidence of radiation-induced cancers was decreased in patients owing to the improvement of therapy. However, a new problem has arisen as to the occurrence of cancers after medical exposure, such as various histological types of cancers after the treatment of skin diseases on the head, and breast cancer after the treatment of pneumothorax. Dose-to-effect relation, hereditary factors, effect of age, immunological influences and endocrine actions were also studied in each radiation-induced cancer. (Ichikawa, K.)

  16. Metabolic studies in man using stable isotopes

    Faust, H.; Jung, K.; Krumbiegel, P.

    1993-01-01

    In this project, stable isotope compounds and stable isotope pharmaceuticals were used (with emphasis on the application of 15 N) to study several aspects of nitrogen metabolism in man. Of the many methods available, the 15 N stable isotope tracer technique holds a special position because the methodology for application and nitrogen isotope analysis is proven and reliable. Valid routine methods using 15 N analysis by emission spectrometry have been demonstrated. Several methods for the preparation of biological material were developed during our participation in the Coordinated Research Programme. In these studies, direct procedures (i.e. use of diluted urine as a samples without chemical preparation) or rapid isolation methods were favoured. Within the scope of the Analytical Quality Control Service (AQCS) enriched stable isotope reference materials for medical and biological studies were prepared and are now available through the International Atomic Energy Agency. The materials are of special importance as the increasing application of stable isotopes as tracers in medical, biological and agricultural studies has focused interest on reliable measurements of biological material of different origin. 24 refs

  17. Design options for advanced manned launch systems

    Freeman, Delma C.; Talay, Theodore A.; Stanley, Douglas O.; Lepsch, Roger A.; Wilhite, Alan W.

    1995-03-01

    Various concepts for advanced manned launch systems are examined for delivery missions to space station and polar orbit. Included are single-and two-stage winged systems with rocket and/or air-breathing propulsion systems. For near-term technologies, two-stage reusable rocket systems are favored over single-stage rocket or two-stage air-breathing/rocket systems. Advanced technologies enable viable single-stage-to-orbit (SSTO) concepts. Although two-stage rocket systems continue to be lighter in dry weight than SSTO vehicles, advantages in simpler operations may make SSTO vehicles more cost-effective over the life cycle. Generally, rocket systems maintain a dry-weight advantage over air-breathing systems at the advanced technology levels, but to a lesser degree than when near-term technologies are used. More detailed understanding of vehicle systems and associated ground and flight operations requirements and procedures is essential in determining quantitative discrimination between these latter concepts.

  18. When does "economic man" dominate social behavior?

    Science.gov (United States)

    Camerer, Colin F; Fehr, Ernst

    2006-01-06

    The canonical model in economics considers people to be rational and self-regarding. However, much evidence challenges this view, raising the question of when "Economic Man" dominates the outcome of social interactions, and when bounded rationality or other-regarding preferences dominate. Here we show that strategic incentives are the key to answering this question. A minority of self-regarding individuals can trigger a "noncooperative" aggregate outcome if their behavior generates incentives for the majority of other-regarding individuals to mimic the minority's behavior. Likewise, a minority of other-regarding individuals can generate a "cooperative" aggregate outcome if their behavior generates incentives for a majority of self-regarding people to behave cooperatively. Similarly, in strategic games, aggregate outcomes can be either far from or close to Nash equilibrium if players with high degrees of strategic thinking mimic or erase the effects of others who do very little strategic thinking. Recently developed theories of other-regarding preferences and bounded rationality explain these findings and provide better predictions of actual aggregate behavior than does traditional economic theory.

  19. Bladder necrosis: 'A man without a bladder'.

    2018-02-17

    Since the use of antibiotics, bladder necrosis has become a rare condition. We report a case of bladder necrosis in a 90-year-old man following urinary retention. After insertion of a transurethral catheter (TUC), 2 L of urine was evacuated. In the following days, the TUC became intermittently blocked. Adequate bladder drainage could not be obtained despite intensive rinsing and placement of a suprapubic catheter. On surgical exploration necrosis of almost the entire bladder wall, except for the trigone, was encountered. Surgical debridement of the non-viable bladder wall without opening the abdominal cavity was conducted, and a TUC was placed in the Retzius cavity to ensure evacuation of urine. Since the patient was haemodynamically unstable, construction of a urinary diversion was waived and urinary drainage of the Retzius cavity by the TUC was accepted, resulting in adequate urinary drainage without compromising renal function. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

  20. NASA Laboratory Analysis for Manned Exploration Missions

    Krihak, Michael K.; Shaw, Tianna E.

    2014-01-01

    The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability Element under the NASA Human Research Program. ELA instrumentation is identified as an essential capability for future exploration missions to diagnose and treat evidence-based medical conditions. However, mission architecture limits the medical equipment, consumables, and procedures that will be available to treat medical conditions during human exploration missions. Allocated resources such as mass, power, volume, and crew time must be used efficiently to optimize the delivery of in-flight medical care. Although commercial instruments can provide the blood and urine based measurements required for exploration missions, these commercial-off-the-shelf devices are prohibitive for deployment in the space environment. The objective of the ELA project is to close the technology gap of current minimally invasive laboratory capabilities and analytical measurements in a manner that the mission architecture constraints impose on exploration missions. Besides micro gravity and radiation tolerances, other principal issues that generally fail to meet NASA requirements include excessive mass, volume, power and consumables, and nominal reagent shelf-life. Though manned exploration missions will not occur for nearly a decade, NASA has already taken strides towards meeting the development of ELA medical diagnostics by developing mission requirements and concepts of operations that are coupled with strategic investments and partnerships towards meeting these challenges. This paper focuses on the remote environment, its challenges, biomedical diagnostics requirements and candidate technologies that may lead to successful blood-urine chemistry and biomolecular measurements in future space exploration missions.

  1. Environmental pathways of radioactivity to man

    Johns, T.F.

    1983-01-01

    An attempt has been made to discuss environmental pathways and their significance in a way which will be understood by non-specialists. The role of these pathways in the general structure of radiological protection is explained and the more important pathways to man from releases into the air and the aquatic environment are discussed generally. The various mechanisms which lead to the dispersion or reconstruction of radioactive materials are discussed and their importance stressed. The more important pathways for particular groups of radionuclides from the nuclear power industry are dealt with in detail and information resulting from many theoretical and practical studies of the situations at particular locations summarized. There is detailed discussion about the doses to local population groups and about worldwide doses as a result of the release of certain long-lived radioactive species. The corresponding pathways and resulting doses from natural radiation are detailed to illustrate that the doses from the nuclear power industry are small in comparison, and brief consideration is given to animal and plant doses from the industry.

  2. Man-machine interface versus full automation

    International Nuclear Information System (INIS)

    Hatton, V.

    1984-01-01

    As accelerators grow in size and complexity of operation there is an increasing economical as well as an operational incentive for the controls and operations teams to use computers to help the man-machine interface. At first the computer network replaced the traditional controls racks filled with knobs, buttons and digital displays of voltages and potentiometer readings. The computer system provided the operator with the extension of his hands and eyes. It was quickly found that much more could be achieved. Where previously it was necessary for the human operator to decide the order of the actions to be executed by the computer as a result of a visual indication of malfunctioning of the accelerator, now the operation is becoming more and more under the direct control of the computer system. Expert knowledge is programmed into the system to help the non-specialist make decision and to safeguard the equipment. Machine physics concepts have been incorporated and critical machine parameters can be optimised easily by the physicists or operators without any detailed knowledge of the intervening medium or of the equipment being controlled. As confidence grows and reliability improves, more and more automation can be added. How far can this process of automation replace the skilled operator. Can the accelerators of tomorrow be run like the ever increasing robotic assembly plants of today. How is the role of the operator changing in this new environment

  4. Vestibular-ocular accommodation reflex in man

    Science.gov (United States)

    Clark, B.; Randle, R. J.; Stewart, J. D.

    1975-01-01

    Stimulation of the vestibular system by angular acceleration produces widespread sensory and motor effects. The present paper studies a motor effect which has not been reported in the literature, i.e., the influence of rotary acceleration of the body on ocular accommodation. The accommodation of 10 young men was recorded before and after a high-level deceleration to zero velocity following 30 sec of rotating. Accommodation was recorded continuously on an infrared optometer for 110 sec under two conditions: while the subjects observed a target set at the far point, and while they viewed the same target through a 0.3-mm pinhole. Stimulation by high-level rotary deceleration produced positive accommodation or a pseudomyopia under both conditions, but the positive accommodation was substantially greater and lasted much longer during fixation through the pinhole. It is hypothesized that this increase in accommodation is a result of a vestibular-ocular accommodation reflex.

    1978-01-01

    A radioimmunoassay (RIA) for oxytocin (OT) in urine is described. 125 I-OT was prepared, and antibodies were raised in rabbits against OT coupled to bovine serumalbumine. This allowed us to set up a RIA for OT which limit of detection is 1.25 pg/tube (0.6 μU). The use of an extraction procedure using CG 50 Amberlite is essential. The recovery after extraction reaches 70.5 %. pH 5 is the optimum pH were urine samples must be stored. The superposition of the elution peak of endogenous OT on that of exogenous hormone is an argument in favour of the validity of such an extraction procedure. Daily urinary excretion of OT reaches 9.58 mU +- 3.48 in 18 healthy young men [fr

    2011-02-01

    From a statutory standpoint, the decision-making capacity of adolescents differs significantly from that of adults because adolescents are considered to lack the experience and judgment necessary to make legally binding decisions. Furthermore, in the case of minors, the principle of protection of life tends to outweigh the principle of autonomy. Here we present the hypothetical case of a 16-year-old boy with spinalmuscular atrophy type II who was admitted to the intensive care unit for severe respiratory distress. We focus on the tension that developed among the patient, his parents, and his physicians when the need for emergency mechanical ventilation became apparent. We review the legal and ethical premises under which adolescents are permitted to make legally binding decisions, ie, the emancipated minor and the mature minor doctrines. Finally, we discuss the concepts of protectionism and liberationism as they apply to adolescents' decision-making capacity.

    Full Text Available Introduction: The skin of modern people is exposed daily to a number of irritants like stress, consequences of inadequate diet, exposure to chemicals and plastics. Those factors can pose a challenge not only for delicate skin of a child, or a woman, but also for more resistant skin of men. Every type of complexion requires individual care, adjusted to different conditions and life circumstances. The choice of proper skin care products should be based on basic skin type and also one's gender. Objectives: Evaluation of differences in students' knowledge about skin care in relation to their gender. Material and methods: Evaluation of students' knowledge concerning proper skin care guidelines was conducted among 210 students (150 women and 60 men using anonymous survey. Results: Majority of male respondents determined their skin type as a normal one (56.6%, majority of female respondents as a combination type (51.3%. Men in contrast to women are more often unable to evaluate the type of their own skin (16.7% vs 4.0%.  Acne was the most common skin condition students of both sexes complained about. Daily skin care activities are performed by 96.6% interviewed women and 63.3% men. The regular use of face skin care products was reported by 87.3% of women and 31.6% of men. Conclusions: 1. Majority of women evaluate their basic skin type as combination one, most men regarded their skin type as normal . 2. Women more often than men take care of their skin and use adequate skin care products. 3. Facial moisturizing lotion is the most frequently chosen skin care product by both women and men.

    Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT scan was performed that a malrotation was identified. The predominant appearances of malrotation are the siting of the ascending colon, caecum (and appendix) in the left side of the abdomen and the right-sided placement of the duodenojejunal junction

    This is the case of a 17-year-old male student who presented to an outpatient clinic with a 3-year episode of increasing anxiety and amotivation related to attending school. Initially affecting only his school work and attendance, the amotivation grew to affect his activities of daily living such as personal hygiene maintenance. There were no discernible psychosocial stressors. The patient did not report any bullying at school or any sort of abuse. At the time of presentation, there were also some depressive symptoms and visual perceptual abnormalities; both appeared subsequent to the amotivation. Escitalopram treated the depressive symptoms and risperidone minimised the perceptual disturbances; methylphenidate was not effective for this patient. The medications did not improve the patient's motivation. At the time of writing, the patient remained in stable state in terms of mood but unable to return to school.

    Nocardiosis is a rare but severe pyogenic or granulomatous disease and caused by Nocardia that mainly infects immunocompromised patients. We report here a case of an immunocompetent 24-year-old male student with community-acquired pneumonia with asymptomatic disseminated cerebral abscess by Brasiliensis nocardiosis. The patient was fully recovered after receiving optimized antimicrobial therapy without relapse. This case suggests the health professionals such as the physicians of pulmonary, infection, neurology department and et al should always think about unusual cause of community acquired pneumonia, even in immunocompetent patients and when having pulmonary nocardiosis we should do a radiological neurological work up, even with the absence of neurological finding or symptom.

    Full Text Available We report a case of a male patient with stroke caused by atrial fibrillation (AF due to thyrotoxicosis. At hospital admission, he presented hypertension and AF. Magnetic resonance imaging confirmed a right-side ischemic area. The thyrotoxicosis was confirmed by thyroid function and thyroid scintigraphy that showed goiter with diffuse hypercaptation. The patient was treated with tapazole and total thyroidectomy, and pathological findings suggested Graves’ disease. Hyperthyroidism is associated with increased supraventricular ectopic activity in patients with a normal heart, and may be an important causal link between hyperthyroidism and AF. The patient experienced significant clinical improvement, but presented long-term neuropsychiatric disorders.

    Full Text Available In order to help the student as a young individual to be manifested into an adult, there is a concern from guidance and counseling sides to the development of this capabilities so that the student could live decently in the future. Effort from guidance and counseling in realizing this educational function, focusing on expanding, internalizing, updating and integrating this value into self-reliable attitude. In such efforts, there are many possibilities from guidance and counseling to utilizing various methods, approaches and techniques, to understand and facilitate the individual development which rests and leads to the human development according to its existensial nature. Because of the cultural diversity that grows and flourished in society, one of the communication approach in counseling which could be implemented is cross-cultural counseling. This research tries to explore and analyzed the data related to the cross cultural counseling conducted by the teacher at Madrasah Aliah Negeri (MAN 2 Brebes towards students with Sundanese ethnic and Javanese ethnic background. This research is a fieldobservational research based, with the type of its data is interview, observation, and documentation. Data reduction techniques, data presentation and conclusion techniques is conducted to analyze the data. Result shows that: firstly, there were similarities of cross-cultural communication conducted by the teacher towards students with Java and Sundanese ethnic background. This similarities are: Bahasa as the same medium in communication, in a specific case using clinical approach, communication skill as empathy, asking, assertiuve and confrontation, posited teachers as a friend and even student’s parent. Secondly, if there is a difference between these two sundanese and Javanese ethnic occurred, it is on rational-emotive approach which is using on Javanese ethnic student, meanwhile non-directive approach is conducted on Sundanese ethnic student.

    Marfan syndrome is a rare connective tissue disorder with a prevalence of approximately 2 to 3 per 10,000 individuals. There have been some reports of young patients with Marfan syndrome developing arteriovenous thromboembolism. These events were unprovoked and recurrent. Owing to its rarity, hypercoagulopathy and other metabolic derangement in patients with Marfan syndrome remains largely unknown. Herein, we report a case of a young man with Marfan syndrome who had myocardial infarction and pulmonary embolism. We hope that this case adds to the scant body of knowledge about this patient population.

    Quantitative description of the physical, and metabolic parameters of the human body is the very basic for internal dosimetry. Compilation of anatomical and other types of data Asian populations for internal (and external) dosimetry is of grate significance because of the potential spread of nuclear energy use in the Asian region and the major contribution of the region to the world population (about 58%). It has been observed that some differences exist for habitat, race, body sizes and pattern of food consumption. In the early stage of revision of ICRP Reference man by the Task Group, Characteristics of the human body of non-European populations received considerable attention as well as those of the European populations of different sexes and ages. In this context, an IAEA-RCA Co-ordinated Research Program on Compilation of Anatomical, Physiological and Metabolic Characteristics for a Reference Asian Man endorsed. In later stages of reference Man revision, anatomical data for Asians was discusses together with those of European populations, presumably due to ICRP's decision of unanimous use of the Reference Man for radiation protection. Reference man models for adults and 15, 10, 5, 1, 0 year-old males and females of Asian populations were developed for use in internal and external dosimetry. Based on the concept of ICRP Reference Man (Publication 23), the reference values were derived from the normal organ mass data for Japanese and statistical data on the physique and nutrition of Japanese and Chinese. Also incorporated were variations in physical measurements, as observed in the above mentioned IAEA-RCA Co-ordinated Research Program. The work was partly carried out within the activities of the ICRP Task Group on Reference Man. The weight of the skeleton was adjusted following the revised values in Publication 70. This paper will report basic shared and non-shared characteristics of Reference Man' for Asians and ICRP Reference Man. (author)

    The development of a completely new series of gas turbines requires significant capital, resources and know-how. MAN Diesel and Turbo strategically decided to create a small gas turbine in the 6 MW-class. The construction of the Gas Turbine has been on the basis of opportunities in current and future markets and the positioning of the competition, this has determined the characteristics and technical parameters which have been optimised in the 6 MW design. The construction uses extremely high precision engineering so that the assembly of sub-components to modules is a smooth flowing process and can guarantee the high standards both quality and performance which MAN Diesel and Turbo are operating to. The individual components must be tested and thoroughly validated many months before actual assembly of the first machine. These include in particular the compressor of the gas turbine and the combustion chamber. The combustion system required special attention, since the emissions are strongly focused to satisfy stringent environmental requirements. The planned tests are a prerequisite for the construction of such a prototype and must be successfully completed before the Gas Turbine will be accepted into service. (orig.)

  8. A Rich Man, Poor Man Story of S-Adenosylmethionine and Cobalamin Revisited.

    Bridwell-Rabb, Jennifer; Grell, Tsehai A J; Drennan, Catherine L

    2018-06-20

    S-adenosylmethionine (AdoMet) has been referred to as both "a poor man's adenosylcobalamin (AdoCbl)" and "a rich man's AdoCbl," but today, with the ever-increasing number of functions attributed to each cofactor, both appear equally rich and surprising. The recent characterization of an organometallic species in an AdoMet radical enzyme suggests that the line that differentiates them in nature will be constantly challenged. Here, we compare and contrast AdoMet and cobalamin (Cbl) and consider why Cbl-dependent AdoMet radical enzymes require two cofactors that are so similar in their reactivity. We further carry out structural comparisons employing the recently determined crystal structure of oxetanocin-A biosynthetic enzyme OxsB, the first three-dimensional structural data on a Cbl-dependent AdoMet radical enzyme. We find that the structural motifs responsible for housing the AdoMet radical machinery are largely conserved, whereas the motifs responsible for binding additional cofactors are much more varied.

    Full Text Available ”Det man hører, er man selv” er Danmarks Radios P3s yderst velkendte slogan. Det dukkede op i begyndelsen af (2000’erne som opfindsom og populær afspejling af en moderne forståelse af den rolle musik og medieforbrug spiller for den voksne dansker. Denne artikel handler ikke om P3 som musikkanal, men går bag om det populære slogan og undersøger hvordan musik og identitet spiller sammen. Hvilke (musikpsykologiske teorier belyser musikkens rolle i identitetsdannelsen? Hvordan forskes der i emnet, og hvilke resultater kan der peges på? Forskningen dokumenterer bl.a., at musik bruges aktivt af mange mennesker som en ressource til at konstruere selv-identitet og gruppe-identitet, og til at skabe, opretholde og regulere en mangfoldighed af følelser. Denne oversigtsartikel giver via præsentation af udvalgte teorier og konkrete undersøgelser en bred introduktion til emnet og viser, hvordan musikforskere gennem arbejde med interviews, dagbøger og (musikalske selvbiografier samt feltarbejde kan beskrive musik som en ofte meget vigtig brik i identitetsdannelsen.

    It is well known, that the president of the first Moldavian Parliament in 1918 was Ion Inculetz (borne on 5 april, 1884, Rezeni vill., Lapusna county, Basarabia - died on 19 november 1940, Bucharest, regraved in Barnova, near Iasi). On 24 January 1918 this Parliament claimed the independence of Basarabia from the Russia (The Democratic Republic of Moldova). On 27 march of the same year in a solennele session the Parliament claimed "The Democratic Republic of Moldova (Basarabia) in its borders between Prut, Dniester rivers, Black Sea, and old borders with Austria, rupted by Russia more than one hundred years from the body of old Moldova, due to the historical right and due to the right of the selfdetermination of peoples, is unifying forever with She's mother Romania ". After the Unification Ion Inculetz activated as representative of Basarabia in the Romanian Parliament. He was a man of democratic views, a partisan of social-democracy in Russia, as well as in Romania after the unification. The progress of peoples was one of His main political goals. It is less known, however, that Inculetz was a remarkable physicist. This is the subject of the conference. After the finish of the secondary studies in Chisinau, He entered to Jur'ev (actually Tartu- Estonia) University Medecine Department, but after one year of studies He moved to Sankt-Petersburg Imperial University, where He specialized in physics and mathematics. After the finish of the Physical Mathematical Department he became private-docent (Associate Professor). Concomittantly He taught methematics at one of the comercial schhols in Sankt Petersburg. In the same time he was a Scientific Secretary of the journal "Nauchnoie Obozrenie" ("Scientific Review") and a researcher at the Meteorological Observatory in Sankt-Petersburg (since 1914). Since 1912 till 1917 He published a series of papers in the fields of physics and meteorology, particularly concerned to anodic rays, Krooks tubes, radiactivity, Doppler effect

  13. Moon manned missions radiation safety analysis

    Tripathi, R. K.; Wilson, J. W.; de Anlelis, G.; Badavi, F. F.

    An analysis is performed on the radiation environment found on the surface of the Moon, and applied to different possible lunar base mission scenarios. An optimization technique has been used to obtain mission scenarios minimizing the astronaut radiation exposure and at the same time controlling the effect of shielding, in terms of mass addition and material choice, as a mission cost driver. The optimization process has been realized through minimization of mass along all phases of a mission scenario, in terms of time frame (dates, transfer time length and trajectory, radiation environment), equipment (vehicles, in terms of shape, volume, onboard material choice, size and structure), location (if in space, on the surface, inside or outside a certain habitats), crew characteristics (number, gender, age, tasks) and performance required (spacecraft and habitat volumes), radiation exposure annual and career limit constraint (from NCRP 132), and implementation of the ALARA principle (shelter from the occurrence of Solar Particle Events). On the lunar surface the most important contribution to radiation exposure is given by background Galactic Cosmic Rays (GCR) particles, mostly protons, alpha particles, and some heavy ions, and by locally induced particles, mostly neutrons, created by the interaction between GCR and surface material and emerging from below the surface due to backscattering processes. In this environment manned habitats are to host future crews involved in the construction and/or in the utilization of moon based infrastructure. Three different kinds of lunar missions are considered in the analysis, Moon Base Construction Phase, during which astronauts are on the surface just to build an outpost for future resident crews, Moon Base Outpost Phase, during which astronaut crews are resident but continuing exploration and installation activities, and Moon Base Routine Phase, with long-term shifting resident crews. In each scenario various kinds of habitats

    The high impulse of electric propulsion makes it an attractive option for manned interplanetary missions such as a manned mission to Mars. This option is, however, dependent on the availability of high energy sources for propulsive power in addition to that required for the manned interplanetary transit vehicle. Two power system technologies are presented: nuclear and solar. The ion thruster technology for the interplanetary transit vehicle is described for a typical mission. The power management and distribution system components required for such a mission must be further developed beyond today's technology status. High voltage-high current technology advancements must be achieved. These advancements are described. In addition, large amounts of waste heat must be rejected to the space environment by the thermal management system. Advanced concepts such as the liquid droplet radiator are discussed as possible candidates for the manned Mars mission. These thermal management technologies have great potential for significant weight reductions over the more conventional systems

  19. Man and Cosmos from the Christian Theology perspective

    Directory of Open Access Journals (Sweden)

    Marin BUGIULESCU

    2017-06-01

    Full Text Available The purpose of this paper is to analyse the theological reflection on the relationship between man and cosmos. The origin of the world and man is connected to God; God is the Creator and consequently the Author of them both. Unlike dualistic materialistic thinking, according to the Christian conception the whole cosmos is created by God. In search for the cosmos an important chapter was granted for man, considered to be a synthesis of the world. Man, from the theological perspective, is the personal, rational, free, and speaking being that has – through the image of God according to which he has been created –, the tension after perfection. But it pertains exclusively to the relationship with Christ in the light of Whom he really knows himself, and by knowing himself he recognizes the infinite beauty of the Archetype. This is the existential-theological truth, which the content of this paper emphasizes, according to the Bible and patristic teaching.

    We measured cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) during light sleep (stage 2) in 8 young healthy volunteers using the Kety-Schmidt technique with 133Xe as the inert gas. Measurements were performed during wakefulness and light sleep as verified by standard...... polysomnography. Unlike our previous study in man showing a highly significant 25% decrease in CMRO2 during deep sleep (stage 3-4) we found a modest but statistically significant decrease of 5% in CMRO2 during stage 2 sleep. Deep and light sleep are both characterized by an almost complete lack of mental activity....... They differ in respect of arousal threshold as a stronger stimulus is required to awaken a subject from deep sleep as compared to light sleep. Our results suggest that during non-rapid eye movement sleep cerebral metabolism and thereby cerebral synaptic activity is correlated to cerebral readiness rather than...

  13. [Knowledge of Man Returns: Some Considerations on Spirituality and Resilience].

    Science.gov (United States)

    Kumakura, Nobuhiro

    2015-01-01

    Over the last decade,"spirituality" and "resilience" have jointly become a topic in psychiatry. The aim of this paper is to discuss the future of psychiatry suggested by this topic. It may be related to what Jaspers, K. called "Knowledge of Man (die Erkenntnis des Menschen)". Knowledge of man in psychiatry can be learned only through clinical experince: e. g., clinical observations and case studies. Modern academic psychiatry seems to be suffering a loss of knowledge of man, which returns periodically in clinical practice. Hence, I will call the re-discovery of the topic in psychiatry as "Return of Man". Since WW II, there have been three eras in which psychiatrists showed deep concern regarding knowledge of man. Firstly, psychopathology and psychotherapy widely developed, when the destructive impulses of mankind were revealed in the nuclear weapons of WW II. Secondly, in the 1970's, the reforms of psychiatric services and legal systems took place somewhat successfully, when social reforms were concerns of the younger generations. Lastly, over the last decade, the topic again returned as spirituality and resilience, when scientists seemed to be powerless in the aftermath of the West Japan Earthquake. Regarding the definition of health made by the WHO in 1946, I further discuss that "Return of Man" in psychiatry is the necessary dynamism between negative and positive health, or between disease control and health promotion. There is an underlying dynamism between "Knowledge of Man" and natural sciences, which is constantly changing. So long as any theory can exist only as a part of dynamism, the Return of Man may re-surface whenever clinical theories do not fit with clinical realities.

    A manned Mars mission will involve a small crew and many complex tasks. The productivity of the crew and the entire mission will depend significantly on effective automation of these tasks and the ease with which the crew can interface with them. The technology to support a manned Mars mission is available today; however, evolving software and electronic technology are enabling many interesting possibilities for increasing productivity and safety while reducing life cycle cost. Some of these advanced technologies are identified.

    137 Cs has been determined in man with the aid of a whole-body counter. It is shown that the specific 137 Cs content (as related to the potassium content in man) continuously decreased from 1965 through 1974. After a slight increase in 1975, possibly caused by a Chinese atmospheric nuclear test in June 1974, the 137 Cs content again decreased in the following years. (author)

    Quantitative description of physical and other characteristics of the human body provides basic data for the estimation of radiation risk and the establishment of dose equivalent in line with the International Commission on Radiological Protection recommendations. ICRP Reference Man is based essentially on data reported on populations in rather limited areas in the world although Committee 2 of ICRP concedes that ''it is neither feasible nor necessary to specify Reference Man as representative of a well-defined population group''. ICRP Reference Man is not necessarily based on the most recent available data. In order to be more realistic and quantitative in dose equivalent estimation in Japan, it is necessary to consider populations which are largely different from those of European and North American countries in physical dimensions and other aspects. Therefore, standard or reference values of mass and size of organs, body and organ content and metabolic parameters of some elements have been studied. These are compared with the values of ICRP Reference Man authorized up to now, with the intention of establishing ''Reference Japanese Man'' and contributing to the improvement of models of man used in radiation protection. Dose equivalent commitment and annual limit of intake have been calculated using the obtained data for the general population in Japan,for some nuclides. (H.K.)

  20. Emblem for the third manned Skylab mission - Skylab 4

    This is the emblem for the third manned Skylab mission. It will be a mission of up to 56 days. The symbols in the patch refer to the three major areas of investigation proposed in the mission. The tree represents man's natural environment and relates directly to the Skylab mission objectives of advancing the study of Earth resources. The hydrogen atom, as the basic building block of the universe, represents man's exploration of the physical world, his application of knowledge, and his development of technology. Since the Sun is composed primarily of hydrogen, it is appropriate that the symbol refers to the solar physics mission objectives. The human silhouette represents mankind and the human capacity to direct technology with a wisdom tempered by regard for his natural environment. It also directly relates to the Skylab medical studies of man himself. The rainbow, adopted from the Biblical story of the flood, symbolizes the promise that is offered man. It embraces man and extends to t
